    2.    REGISTRATION
      RIGHTS.

     

    2.1 Demand
      Registration.

     

    2.1.1 Request
      for Registration.
      At any
      time and from time to time on or after the Release Date, the holders of not
      less
      than a majority of any class of the Registrable Securities held by the Investors
      or the transferees of the Investors, may make a written demand for registration
      under the Securities Act of all or part of their Registrable Securities (a
      “Demand Registration”). Any demand for a Demand Registration 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
      Registrable Securities of the demand, and 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 2.1.4 and the provisos set forth in Section 3.1.1. The
      Company shall not be obligated to effect more than an aggregate of two (2)
      Demand Registrations under this Section 2.1.1 in respect of Registrable
      Securities.

     

    2.1.2 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      stop order or injunction is removed, rescinded or otherwise terminated, and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; provided, further, that the Company shall not be obligated to file
      a
      second Registration Statement until a Registration Statement that has been
      filed
      is counted as a Demand Registration or is terminated or withdrawn.

     

    2.1.3 Underwritten
      Offering.
      If not
      less than a majority interest of the Demanding Holders so elect and such holders
      so advise the Company as part of their written demand for a Demand Registration,
      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 a majority-in-interest of the holders initiating the Demand
      Registration.

    2.1.4 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 Ordinary Shares
      or other securities which the Company desires to sell and the Ordinary Shares,
      if any, as to which registration has been requested pursuant to written
      contractual piggy-back registration rights held by other shareholders 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 of Registrable Securities which such
      Demanding Holder has requested be included in such registration, regardless
      of
      the number of shares of Registrable Securities held by each Demanding Holder)
      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 Ordinary Shares 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 Ordinary Shares 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; and (v) fourth, to the extent that
      the
      Maximum Number of Shares have not been reached under the foregoing clauses
      (i),
      (ii), and (iii), the Ordinary Shares that other shareholders desire to sell
      that
      can be sold without exceeding the Maximum Number of Shares.

     

    2.1.5 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 such registration shall not count as a Demand Registration
      provided for in this Section 2.1.

    2.2 Piggy-Back
      Registration.

     

    2.2.1 Piggy-Back
      Rights.
      If at
      any time on or after the Release Date the Company proposes to file a
      Registration Statement under the Securities 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 shareholders of the Company for their account (or by the
      Company and by shareholders of the Company including, without limitation,
      pursuant to Section 2.1), 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
      shareholders, (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 to be included 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.

     

    2.2.2 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 Ordinary Shares which
      the Company desires to sell, taken together with Ordinary Shares, 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 2.2, and the Ordinary Shares, if any, as to which
      registration has been requested pursuant to the written contractual piggy-back
      registration rights of other shareholders of the Company, exceeds the Maximum
      Number of Shares, then the Company shall include in any such
      registration:

     

    (i) If
      the
      registration is undertaken for the Company’s account: (A) first, the Ordinary
      Shares or other securities that the Company desires to
      sell
      that can be sold without exceeding the Maximum Number of Shares; (B) second,
      to
      the extent that the Maximum Number of Shares has not been reached under the
      foregoing clause (A), the Ordinary Shares, if any, including the Registrable
      Securities, as to which registration has been requested pursuant to written
      contractual piggy-back registration rights of security holders (pro rata in
      accordance with the number of Ordinary Shares which each such person has
      actually requested to be included in such registration, regardless of the number
      of Ordinary Shares with respect
      to which such persons have the
      right
      to request such inclusion) that can be sold without exceeding the Maximum Number
      of Shares; and 

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

     

    (ii) If
      the
      registration is a “demand” registration
      undertaken at the demand of persons other than the holders of Registrable
      Securities pursuant to written contractual
      arrangements with such persons, (A) first, the Ordinary Shares 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 has
      not
      been reached under the foregoing clause (A), the Ordinary Shares or other
      securities that the Company desires to sell 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) and (B),
      the Registrable Securities as to which registration has been requested under
      this Section 2.2 (pro rata in accordance with the number of shares of
      Registrable Securities held by each such holder); 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 Ordinary Shares, if any, as to which registration
      has been requested pursuant to written contractual piggy-back registration
      rights which other shareholders desire to sell that can be sold without
      exceeding the Maximum Number of Shares.

     

    2.2.3 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 may also elect to
      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 3.3.

     

    2.3 Registrations
      on Form F-3.
      The
      holders of Registrable Securities may at any time and from time to time, request
      in writing that the Company register the resale of any or all of such
      Registrable Securities on Form F-3 or any similar short-form registration which
      may be available at such time (“Form F-3”); provided, however, that the Company
      shall not be obligated to effect such request through an underwritten offering.
      Upon receipt of such written request, the Company will promptly give written
      notice of the proposed registration to all other holders of Registrable
      Securities, and, as soon as practicable thereafter, effect the registration
      of
      all or such portion of such holder’s or holders’ Registrable Securities as are
      specified in such request, together with all or such portion of the Registrable
      Securities of any other holder or holders joining in such request as are
      specified in a written request given within fifteen (15) days after receipt
      of
      such written notice from the Company; provided, however, that the Company shall
      not be obligated to effect any such registration pursuant to this Section 2.3:
      (i) if Form F-3 is not available for such offering; or (ii) if the holders
      of
      the Registrable Securities, together with the holders of any other securities
      of
      the Company entitled to inclusion in such registration, propose to sell
      Registrable Securities and such other securities (if any) at any aggregate
      price
      to the public of less than $500,000. Registrations effected pursuant to this
      Section 2.3 shall not be counted as Demand Registrations effected pursuant
      to
      Section 2.1.

     

    3.    REGISTRATION
      PROCEDURES.

     

    3.1 Filings;
      Information.
      Whenever the Company is required to effect the registration of any Registrable
      Securities pursuant to Section 2, the Company shall use its best efforts to
      effect the registration and sale of such Registrable Securities in accordance
      with the intended method(s) of distribution thereof as expeditiously as
      practicable, and in connection with any such request:

    3.1.1 Filing
      Registration Statement.
      The
      Company shall, as expeditiously as possible and in any event within sixty (60)
      days after receipt of a request for a Demand Registration pursuant to Section
      2.1, prepare and file with the Commission a Registration Statement on any form
      for which the Company then qualifies or which counsel for the Company shall
      deem
      appropriate and which form shall be available for the sale of all Registrable
      Securities to be registered thereunder in accordance with the intended method(s)
      of distribution thereof, and shall use its best efforts to cause such
      Registration Statement to become and remain effective for the period required
      by
      Section 3.1.3; provided, however, that the Company shall have the right to
      defer
      any Demand Registration for up to thirty (30) days, and any Piggy-Back
      Registration for such period as may be applicable to deferment of any demand
      registration to which such Piggy-Back Registration relates, in each case if
      the
      Company shall furnish to the holders a certificate signed by the Chief Executive
      Officer of the Company stating that, in the good faith judgment of the Board
      of
      Directors of the Company, it would be materially detrimental to the Company
      and
      its shareholders for such Registration Statement to be effected at such time;
      provided further, however, that the Company shall not have the right to exercise
      the right set forth in the immediately preceding proviso more than once in

      amendment or supplement thereto, furnish without charge to the holders of
      Registrable Securities included in such registration, and such holders’ legal
      counsel, copies of such Registration Statement as proposed to be filed, each
      amendment and supplement to such Registration Statement (in each case including
      all exhibits thereto and documents incorporated by reference therein), the
      prospectus included in such Registration Statement (including each preliminary
      prospectus), and such other documents as the holders of Registrable Securities
      included in such registration or legal counsel for any such holders may request
      in order to facilitate the disposition of the Registrable Securities owned
      by
      such holders.

     

    3.1.3 Amendments
      and Supplements.
      The
      Company shall prepare and file with the Commission such amendments, including
      post-effective amendments, and supplements to such Registration Statement and
      the prospectus used in connection therewith as may be necessary to keep such
      Registration Statement effective and in compliance with the provisions of the
      Securities Act until all Registrable Securities and other securities covered
      by
      such Registration Statement have been disposed of in accordance with the
      intended method(s) of distribution set forth in such Registration Statement
      (which period shall not exceed the sum of one hundred eighty (180) days plus
      any
      period during which any such disposition is interfered with by any stop order
      or
      injunction of the Commission or any governmental agency or court) or such
      securities have been withdrawn.

      After
      the filing of a Registration Statement, the Company shall promptly, and in
      no
      event more than two (2) business days after such filing, notify the holders
      of
      Registrable Securities included in such Registration Statement of such filing,
      and shall further notify such holders promptly and confirm such advice in
      writing in all events within two (2) business days of the occurrence of any
      of
      the following: (i) when such Registration Statement becomes effective; (ii)
      when
      any post-effective amendment to such Registration Statement becomes effective;
      (iii) the issuance or threatened issuance by the Commission of any stop order

      for any amendment or supplement to such Registration Statement or any prospectus
      relating thereto or for additional information or of the occurrence of an event
      requiring the preparation of a supplement or amendment to such prospectus so
      that, as thereafter delivered to the purchasers of the securities covered by
      such Registration Statement, such prospectus will not contain an untrue
      statement of a material fact or omit to state any material fact required to
      be
      stated therein or necessary to make the statements therein not misleading,
      and
      promptly make available to the holders of Registrable Securities included in
      such Registration Statement any such supplement or amendment; except that before
      filing with the Commission a Registration Statement or prospectus or any
      amendment or supplement thereto, including documents incorporated by reference,
      the Company shall furnish to the holders of Registrable Securities included
      in
      such Registration Statement and to the legal counsel for any such holders,
      copies of all such documents proposed to be filed sufficiently in advance of
      filing to provide such holders and legal counsel with a reasonable opportunity
      to review such documents and comment thereon, and the Company shall not file
      any
      Registration Statement or prospectus or amendment or supplement thereto,
      including documents incorporated by reference, to which such holders or their
      legal counsel shall object.

     

    3.1.5 State
      Securities Laws Compliance.
      The
      Company shall use its best efforts to (i) register or qualify the Registrable
      Securities covered by the Registration Statement under such securities or “blue
      sky” laws of such jurisdictions in the United States as the holders of
      Registrable Securities included in such Registration Statement (in light of
      their intended plan of distribution) may request and (ii) take such action
      necessary to cause such Registrable Securities covered by the Registration
      Statement to be registered with or approved by such other Governmental
      Authorities as may be necessary by virtue of the business and operations of
      the
      Company and do any and all other acts and things that may be necessary or
      advisable to enable the holders of Registrable Securities included in such
      Registration Statement to consummate the disposition of such Registrable
      Securities in such jurisdictions; provided, however, that the Company shall
      not
      be required to qualify generally to do business in any jurisdiction where it
      would not otherwise be required to qualify but for this paragraph 3.1.5 or
      subject itself to taxation in any such jurisdiction.

     

    3.1.6 Agreements
      for Disposition.
      The
      Company shall enter into customary agreements (including, if applicable, an
      underwriting agreement in customary form) and take such other actions as are
      reasonably required in order to expedite or facilitate the disposition of such
      Registrable Securities. The representations, warranties and covenants of the
      Company in any underwriting agreement which are made to or for the benefit
      of
      any Underwriters, to the extent applicable, shall also be made to and for the
      benefit of the holders of Registrable Securities included in such registration
      statement. No holder of Registrable Securities included in
      such
      registration statement shall be required to make any representations or
      warranties in the underwriting agreement except, if applicable, with respect
      to
      such holder’s organization, good standing, authority, title to Registrable
      Securities, lack of conflict of such sale with such holder’s material agreements
      and organizational documents, and with respect to written information relating
      to such holder that such holder has furnished in writing expressly for inclusion
      in such Registration Statement.

    3.1.7 Cooperation.
      The
      principal executive officer of the Company, the principal financial officer
      of
      the Company, the principal accounting officer of the Company and all other
      officers and members of the management of the Company shall cooperate fully
      in
      any offering of Registrable Securities hereunder, which cooperation shall
      include, without limitation, the preparation of the Registration Statement
      with
      respect to such offering and all other offering materials and related documents,
      and participation in meetings with Underwriters, attorneys, accountants and
      potential investors.

     

    3.1.8 Records.
      The
      Company shall make available for inspection by the holders of Registrable
      Securities included in such Registration Statement, any Underwriter
      participating in any disposition pursuant to such registration statement and
      any
      attorney, accountant or other professional retained by any holder of Registrable
      Securities included in such Registration Statement or any Underwriter, all
      financial and other records, pertinent corporate documents and properties of
      the
      Company, as shall be necessary to enable them to exercise their due diligence
      responsibility, and cause the Company’s officers, directors and employees to
      supply all information requested by any of them in connection with such
      Registration Statement.

     

    3.1.9 Opinions
      and Comfort Letters.
      The
      Company shall furnish to each holder of Registrable Securities included in
      any
      Registration Statement a signed counterpart, addressed to such holder, of (i)
      any opinion of counsel to the Company delivered to any Underwriter and (ii)
      any
      comfort letter from the Company’s independent public accountants delivered to
      any Underwriter. In the event no legal opinion is delivered to any Underwriter,
      the Company shall furnish to each holder of Registrable Securities included
      in
      such Registration Statement, at any time that such holder elects to use a
      prospectus, an opinion of counsel to the Company to the effect that the
      Registration Statement containing such prospectus has been declared effective
      and that no stop order is in effect.

     

    3.1.10 Earnings
      Statement.
      The
      Company shall comply with all applicable rules and regulations of the Commission
      and the Securities Act, and make available to its shareholders, as soon as
      practicable, an earnings statement covering a period of twelve (12) months,
      beginning within three (3) months after the effective date of the registration
      statement, which earnings statement shall satisfy the provisions of Section
      11(a) of the Securities Act and Rule 158 thereunder.

     

    3.1.11 Listing.
      The
      Company shall use its best efforts to cause all Registrable Securities included
      in any registration to be listed on such exchanges or otherwise designated
      for
      trading in the same manner as similar securities issued by the Company are
      then
      listed or designated or, if no such similar securities are then listed or
      designated, in a manner satisfactory to the holders of a majority of the
      Registrable Securities included in such registration.

     

    3.2 Obligation
      to Suspend Distribution.
      Upon
      receipt of any notice from the Company of the happening of any event of the
      kind
      described in Section 3.1.4(iv), or, in the case of a resale registration on
      Form
      F-3 pursuant to Section 2.3 hereof, upon any suspension by the Company, pursuant
      to a written insider trading compliance program adopted by the Company’s Board
      of Directors, of the ability of all “insiders” covered by such program to
      transact in the Company’s securities because of the existence of material
      non-public information, each holder of Registrable Securities included in any
      registration shall immediately discontinue disposition of such Registrable
      Securities pursuant to the Registration Statement covering such Registrable
      Securities until such holder receives the supplemented or amended prospectus
      contemplated by Section 3.1.4(iv) or the restriction on the ability of
“insiders” to transact in the Company’s securities is removed, as applicable,
      and, if so directed by the
      Company,
      each such holder will deliver to the Company all copies, other than permanent
      file copies then in such holder’s possession, of the most recent prospectus
      covering such Registrable Securities at the time of receipt of such
      notice.

    3.3 Registration
      Expenses.
      The
      Company shall bear all costs and expenses incurred in connection with any Demand
      Registration pursuant to Section 2.1, any Piggy-Back Registration pursuant
      to
      Section 2.2, and any registration on Form F-3 effected pursuant to Section
      2.3,
      and all expenses incurred in performing or complying with its other obligations
      under this Agreement, whether or not the Registration Statement becomes
      effective, including, without limitation: (i) all registration and filing fees;
      (ii) fees and expenses of compliance with securities or “blue sky” laws
      (including fees and disbursements of counsel in connection with blue sky
      qualifications of the Registrable Securities); (iii) printing expenses; (iv)
      the
      Company’s internal expenses (including, without limitation, all salaries and
      expenses of its officers and employees); (v) the fees and expenses incurred

      3.1.11; (vi) National Association of Securities Dealers, Inc. fees; (vii) fees
      and disbursements of counsel for the Company and fees and expenses for
      independent certified public accountants retained by the Company (including
      the
      expenses or costs associated with the delivery of any opinions or comfort
      letters requested pursuant to Section 3.1.9); (viii) the fees and expenses
      of
      any special experts retained by the Company in connection with such registration
      and (ix) the fees and expenses of one legal counsel selected by the holders
      of a
      majority-in-interest of the Registrable Securities included in such
      registration. The Company shall have no obligation to pay any underwriting
      discounts or selling commissions attributable to the Registrable Securities
      being sold by the holders thereof, which underwriting discounts or selling
      commissions shall be borne by such holders. Additionally, in an underwritten
      offering, all selling shareholders and the Company shall bear the expenses
      of
      the underwriter pro rata in proportion to the respective amount of shares each
      is selling in such offering.

     

    3.4 Information.
      The
      holders of Registrable Securities shall provide such information as may
      reasonably be requested by the Company, or the managing Underwriter, if any,
      in
      connection with the preparation of any Registration Statement, including
      amendments and supplements thereto, in order to effect the registration of
      any
      Registrable Securities under the Securities Act pursuant to Section 2 and in
      connection with the Company’s obligation to comply with federal and applicable
      state securities laws.

    4.    INDEMNIFICATION
      AND CONTRIBUTION.

     

    4.1 Indemnification
      by the Company.
      The
      Company agrees to indemnify and hold harmless each Investor and each other
      holder of Registrable Securities, and each of their respective officers,
      employees, affiliates, directors, partners, members, attorneys and agents,
      and
      each person, if any, who controls an Investor and each other holder of
      Registrable Securities (within the meaning of Section 15 of the Securities
      Act
      or Section 20 of the Exchange Act) (each, an “Investor Indemnified Party”), from
      and against any expenses, losses, judgments, claims, damages or liabilities,
      whether joint or several, arising out of or based upon any untrue statement
      (or
      allegedly untrue statement) of a material fact contained in any Registration
      Statement under which the sale of such Registrable Securities was registered
      under the Securities Act, any preliminary prospectus, final prospectus or
      summary prospectus contained in the Registration Statement, or any amendment
      or
      supplement to such Registration Statement, or arising out of or based upon
      any
      omission (or alleged omission) to state a material fact required to be stated
      therein or necessary to make the statements therein not misleading, or any
      violation by the Company of the Securities Act or any rule or regulation
      promulgated thereunder applicable to the Company and relating to action or
      inaction required of the Company in connection with any such registration;
      and
      the Company shall promptly reimburse the Investor Indemnified Party for any
      legal and any other expenses reasonably incurred by such Investor Indemnified
      Party in connection with investigating and defending any such expense, loss,
      judgment, claim, damage, liability or action; provided, however, that the
      Company will not be liable in any such case to the extent that any such expense,
      loss, claim, damage or liability arises out of or is based upon any untrue
      statement or allegedly untrue statement or omission or alleged omission made
      in
      such Registration Statement, preliminary prospectus, final prospectus, or
      summary prospectus, or any such amendment or supplement, in reliance upon and
      in
      conformity with information furnished to the Company, in writing, by such
      selling holder expressly for use therein. The Company also shall indemnify
      any
      Underwriter of the Registrable Securities, their officers, affiliates,
      directors, partners, members and agents and each person who controls such
      Underwriter on substantially the same basis as that of the indemnification
      provided above in this Section 4.1.

     

    4.2 Indemnification
      by Holders of Registrable Securities.
      Each
      selling holder of Registrable Securities will, in the event that any
      registration is being effected under the Securities Act pursuant to this
      Agreement of any Registrable Securities held by such selling holder, indemnify
      and hold harmless the Company, each of its directors and officers and each
      underwriter (if any), and each other person, if any, who controls the company
      or
      such underwriter within the meaning of the Securities Act, against any losses,
      claims, judgments, damages or liabilities, whether joint or several, insofar
      as
      such losses, claims, judgments, damages or liabilities (or actions in respect
      thereof) arise out of or are based upon any untrue statement or allegedly untrue
      statement of a material fact contained in any Registration Statement under
      which
      the sale of such Registrable Securities was registered under the Securities
      Act,
      any preliminary prospectus, final prospectus or summary prospectus contained
      in
      the Registration Statement, or any amendment or supplement to the Registration
      Statement, or arise out of or are based upon any omission or the alleged
      omission to state a material fact required to be stated therein or necessary
      to
      make the statement therein not misleading, if the statement or omission was
      made
      in reliance upon and in conformity with information furnished in writing to
      the
      Company by such selling holder expressly for use therein, and shall reimburse
      the Company, its directors and officers, and each such controlling person for
      any legal or other expenses reasonably incurred by any of them in connection
      with investigation or defending any such loss, claim, damage, liability or
      action. Each selling holder’s indemnification obligations hereunder shall be
      several and not joint and shall be limited to the amount of any net proceeds
      actually received by such selling holder.

    
      
        
        

      

      
        11

        
          

        

      

      
        
        

      

    

     

    4.3 Conduct
      of Indemnification Proceedings.
      Promptly after receipt by any person of any notice of any loss, claim, damage
      or
      liability or any action in respect of which indemnity may be sought pursuant
      to
      Section 4.1 or 4.2, such person (the “Indemnified Party”) shall, if a claim in
      respect thereof is to be made against any other person for indemnification
      hereunder, notify such other person (the “Indemnifying Party”) in writing of the
      loss, claim, judgment, damage, liability or action; provided, however, that
      the
      failure by the Indemnified Party to notify the Indemnifying Party shall not
      relieve the Indemnifying Party from any liability which the Indemnifying Party
      may have to such Indemnified Party hereunder, except and solely to the extent
      the Indemnifying Party is actually prejudiced by such failure. If the
      Indemnified Party is seeking indemnification with respect to any claim or action
      brought against the Indemnified Party, then the Indemnifying Party shall be
      entitled to participate in such claim or action, and, to the extent that it
      wishes, jointly with all other Indemnifying Parties, to assume control of the
      defense thereof with counsel satisfactory to the Indemnified Party. After notice
      from the Indemnifying Party to the Indemnified Party of its election to assume
      control of the defense of such claim or action, the Indemnifying Party shall
      not
      be liable to the Indemnified Party for any legal or other expenses subsequently
      incurred by the Indemnified Party in connection with the defense thereof other
      than reasonable costs of investigation; provided, however, that in any action
      in
      which both the Indemnified Party and the Indemnifying Party are named as
      defendants, the Indemnified Party shall have the right to employ separate
      counsel (but no more than one such separate counsel) to represent the
      Indemnified Party and its controlling persons who may be subject to liability
      arising out of any claim in respect of which indemnity may be sought by the
      Indemnified Party against the Indemnifying Party, with the fees and expenses
      of
      such counsel to be paid by such Indemnifying Party if, based upon the written
      opinion of counsel of such Indemnified Party, representation of both parties
      by
      the same counsel would be inappropriate due to actual or potential differing
      interests between them. No Indemnifying Party shall, without the prior written
      consent of the Indemnified Party, consent to entry of judgment or effect any
      settlement of any claim or pending or threatened proceeding in respect of which
      the Indemnified Party is or could have been a party and indemnity could have
      been sought hereunder by such Indemnified Party, unless such judgment or
      settlement includes an unconditional release of such Indemnified Party from
      all
      liability arising out of such claim or proceeding.

     

    4.4
      Contribution.

     

    4.4.1 If
      the
      indemnification provided for in the foregoing Sections 4.1, 4.2 and 4.3 is
      unavailable to any Indemnified Party in respect of any loss,
      claim,
      damage, liability or action referred to herein, then each such Indemnifying
      Party, in lieu of indemnifying such Indemnified Party, shall contribute to
      the
      amount paid or payable by such Indemnified Party as a result of such loss,
      claim, damage, liability or action in such proportion as is appropriate to
      reflect the relative fault of the Indemnified Parties and the Indemnifying
      Parties in connection with the actions or omissions which resulted in such
      loss,
      claim, damage, liability or action, as well as any other relevant equitable
      considerations. The relative fault of any Indemnified Party and any Indemnifying
      Party shall be determined by reference to, among other things, whether the
      untrue or alleged untrue statement of a material fact or the omission or alleged
      omission to state a material fact relates to information supplied by such
      Indemnified Party or such Indemnifying Party and the parties’ relative intent,
      knowledge, access to information and opportunity to correct or prevent such
      statement or omission.

     

    4.4.2 The
      parties hereto agree that it would not be just and equitable if contribution
      pursuant to this Section 4.4 were determined by pro rata allocation or by any
      other method of allocation which does not take account of the equitable
      considerations referred to in the immediately preceding Section 4.4.1. The
      amount paid or payable by an Indemnified Party as a result of any loss, claim,
      damage, liability or action referred to in the immediately preceding paragraph
      shall be deemed to include, subject to the limitations set forth above, any
      legal or other expenses incurred by such Indemnified Party in connection with
      investigating or defending any such action or claim. Notwithstanding the
      provisions of this Section 4.4, no holder of Registrable Securities shall be
      required to contribute any amount in excess of the dollar amount of the net
      proceeds (after payment of any underwriting fees, discounts, commissions or
      taxes) actually received by such holder from the sale of Registrable Securities
      which gave rise to such contribution obligation. No person guilty of fraudulent
      misrepresentation (within the meaning of Section 11(f) of the Securities Act)
      shall be entitled to contribution from any person who was not guilty of such
      fraudulent misrepresentation.

    5.    UNDERWRITING
      AND DISTRIBUTION.

     

    5.1 Rule
      144.
      The
      Company covenants that it shall file all reports required to be filed by it
      under the Securities 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

    6.10
      Remedies.

     

    6.10.1 Specific
      Performance.
      Each of
      the parties acknowledges and agrees that the other parties would be damaged
      irreparably in the event any of the provisions of this Agreement are not
      performed in accordance with their specific terms or otherwise are breached.
      Accordingly, each of the parties agrees that the other parties shall be entitled
      to an injunction or injunctions (without the necessity of posting a bond or
      other security) to prevent breaches of the provisions of this Agreement and
      to
      enforce specifically this Agreement and the terms and provisions hereof in
      any
      action instituted in any court of the United States or any state or other
      foreign court or governmental body having jurisdiction over the parties and
      the
      matter, in addition to any other remedy to which they may be entitled, at law
      or
      in equity.

     

    6.10.2 Repurchase
      Obligation.
      In the
      event that the Company breaches its obligations under Section 2 or Section
      3 of
      this Agreement, the Investors shall have the right to cause the Company to
      purchase the Registrable Securities that were the subject of such breach (the
      “Repurchase Right”), as follows:

     

    (a) In
      the
      event an Investor wishes to exercise its Repurchase Right, the Investor shall
      notify the Company in writing of the alleged breach of Section 2 or Section
      3
      and the Registrable Securities that were the subject of such
      breach.

     

    (b) In
      the
      event that the Company does not remedy or cure such breach within thirty (30)
      days of the receipt of the written notice set out in Section 6.10.2(a) above,
      then the Company shall be irrevocably obligated to purchase from the Investor
      the Registrable Securities that were the subject of such breach. The closing
      of
      such repurchase shall take place within sixty (60) days of such
      notice.

     

    
      
        
        

      

      
        15

        
          

        

      

      
        
        

      

    

     

    (c) The
      purchase price for the Registrable Securities to be repurchased pursuant to
      the
      exercise of this Repurchase Right shall be equal to the average of the closing
      prices for the applicable Registrable Securities for the last 20 trading days
      prior to the day that the closing of the repurchase of such Registrable
      Securities is to occur hereunder.

     

    (d) If
      the
      Company is unable to purchase all Registrable Securities required to be
      purchased hereunder due to legal or contractual restrictions (as evidenced
      by
      the opinion letter of outside counsel to the Company acceptable to the Investors
      which shall attach the relevant law, regulation and/or contract), Registrable
      Securities shall be repurchased (on a pro rata basis from the holders of the
      Registrable Securities based upon the Ordinary Share equivalents) from time
      to
      time within thirty (30) days after such legal or contractual restriction is
      lifted, to the extent the Company is legally permitted to do so, and the
      obligations of the Company under this Section 6.10.2 will be a continuing
      obligation until the Company’s repurchase of all such Registrable
      Securities.

     

    (e) On
      each
      date (including any subsequent purchase closing date if multiple purchases
      result from the application of Section 6.10.2(d)) that a purchase is to occur
      hereunder, the closing shall occur at the Company’s principal office. At the
      closing, to the extent applicable, the Investor shall deliver the Registrable
      Securities being sold, duly endorsed in blank, accompanied by such supporting
      documents as may be necessary to pass to the Company good title to the
      Registrable Securities, free and clear of all liens (other than restrictions
      under applicable securities laws). In consideration therefor, the Company shall
      deliver to the Investor immediately available funds equal to the aggregate
      purchase price as determined hereunder. If the Company fails to purchase the
      Registrable Securities on any closing date, it shall pay interest to each
      Investor for the period commencing on the date of such closing and ending on
      the
      date such purchase is made equal to the US dollar prime rate by Citibank N.A.
      for such period (broker down to shorter periods if relevant) plus four percent
      (4%).

     

    (f) At
      any
      time prior to the sale of any Registrable Securities under this Section 6.10.2,
      the Investor may withdraw its notice, without impairing its right to exercise
      its rights pursuant to this Section 6.10.2 at a later date.

     

    6.11 Remedies
      Cumulative.
      In the
      event that the Company fails to observe or perform any covenant or agreement
      to
      be observed or performed under this Agreement, the Investor or any other holder
      of Registrable Securities may proceed to protect and enforce its rights by
      suit
      in equity or action at law, whether for specific performance of any term
      contained in this Agreement or for an injunction against the breach of any
      such
      term or in aid of the exercise of any power granted in this Agreement or to
      enforce any other legal or equitable right, or to take any one or more of such
      actions, without being required to post a bond. None of the rights, powers
      or
      remedies conferred under this Agreement shall be mutually exclusive, and each
      such right, power or remedy shall be cumulative and in addition to any other
      right, power or remedy, whether conferred by this Agreement or now or hereafter
      available at law, in equity, by statute or otherwise.

     

    6.12 Governing
      Law.
      This
      Agreement shall be governed by, interpreted under, and construed in accordance
      with the internal laws of the State of New York applicable to agreements made
      and to be performed within the State of New York, without giving effect to
      any
      choice-of-law provisions thereof that would compel the application of the
      substantive laws of any other jurisdiction.

    6.13 Waiver
      of Trial by Jury.
      Each
      party hereby irrevocably and unconditionally waives the right to a trial by
      jury
      in any action, suit, counterclaim or other proceeding (whether based on
      contract, tort or otherwise) arising out of, connected with or relating to
      this
      Agreement, the transactions contemplated hereby, or the actions of the Investor
      in the negotiation, administration, performance or enforcement
      hereof.

        18REVOLVING
      LINE OF CREDIT AGREEMENT

     

    This
      Revolving Line of Credit Agreement (this “Agreement”)
      is
      made as of August 14, 2007 by and among Hambrecht Asia Acquisition Corp., a
      Cayman Islands company (“Borrower”),
      and
      each other signatory hereto (each a “Lender”
and
      collectively, the “Lenders”),
      with
      reference to the following facts.

     

    (a) Borrower
      has been organized for the purpose of effecting a merger, capital stock
      exchange, asset acquisition or other similar business combination with an
      operating business (a “Business
      Combination”).

     

    (b) Borrower
      proposes to: (a) make a public offering (the “Public
      Offering”)
      of its
      securities pursuant to a registration statement (the “Registration
      Statement”)
      filed
      with and declared effective by the Securities and Exchange Commission (the
      “SEC”);
      (b)
      deposit the proceeds from the Public Offering into a trust account (the
“Trust
      Account”)
      for
      the benefit of the purchasers of securities in the Public Offering, net of
      offering costs, underwriting discounts and a financial advisory fee, to be
      held
      and disbursed in accordance with the terms of the Investment Management Trust
      Agreement to be entered into between Borrower and Continental Stock Transfer
      & Trust Company as trustee (the “Trust
      Agreement”);
      and
      (c) utilize the funds in the Trust Account in connection with a Business
      Combination.

     

    (c) Borrower
      may need funds to pay costs and expenses prior to consummation of a Business
      Combination.

     

    (d) On
      the
      terms and subject to the conditions set forth in this Agreement, Lenders are
      willing to make available to Borrower a revolving line of credit to pay certain
      costs and expenses that may arise prior to a Business Combination.

     

    AGREEMENT

     

    1.    The
      Loans

     

    1.1 Subject
      to the terms and conditions of this Agreement, during the period from the date
      hereof until the Termination Date, each Lender severally, but not jointly,
      agrees, to make advances (each advance, a “Loan”
and
      collectively, the “Loans”)
      to
      Borrower in an aggregate amount not to exceed such Lender’s Commitment, and
      Borrower agrees to repay such Loans, from time to time in accordance with the
      terms and conditions of this Agreement and the revolving line of credit notes
      (each, a “Note”
and
      collectively, the “Notes”)
      issued
      in connection herewith, a form of which is attached hereto as Exhibit A;
      provided, however, that notwithstanding anything herein to the contrary, at
      no
      time shall any Lender be required to make Loans in excess of such Lender’s Pro
      Rata Share of the amount by which the Commitments of Lenders exceeds the
      outstanding Loans. This Agreement and the Notes are sometimes referred to in
      this Agreement individually as a “Loan
      Document,”
and
      are sometimes collectively referred to as the “Loan
      Documents.”
The
      term “Commitment”
shall
      mean, with respect to a Lender, the principal amount set forth beside such
      Lender’s name under the heading “Commitment” on the signature pages to this
      Agreement, as such Commitment may be adjusted from time to time in accordance
      with section 8.5 herein and the term “Commitments”
shall
      mean, collectively, the aggregate
      amount of the commitments of all of the Lenders. The term “Pro
      Rata Share”
shall
      mean, with respect to a Lender, the percentage obtained by dividing (a) such
      Lender’s Commitment by (b) the sum of all of the Lenders’ Commitments, or if the
      Commitments are terminated, the percentage obtained by dividing (1) the
      Obligations owing to such Lender by (2) the sum of all of the Lenders’
Obligations. The term “Obligations”
shall
      mean all amounts, obligations, liabilities, covenants and duties of every type
      and description owing by Borrower to any Lender arising out of, under, or in
      connection with, any Loan Document, whether direct or indirect (regardless
      of
      whether acquired by assignment), absolute or contingent, due or to become due,
      whether liquidated or not, now existing or hereafter arising and however
      acquired, and whether or not evidenced by any instrument or for the payment
      of
      money, including, without duplication, (a) all Loans, (b) all interest, whether
      or not accruing after the filing of any petition in bankruptcy or after the
      commencement of any insolvency, reorganization or similar proceeding, and
      whether or not a claim for post-filing or post-petition interest is allowed
      in
      any such proceeding, and (c) all other fees, expenses (including fees, charges
      and disbursement of counsel), interest, commissions, charges, costs,
      disbursements, indemnities and reimbursement of amounts paid and other sums
      chargeable to Borrower under any Loan Document. The term “Termination
      Date”
shall
      mean the earliest of (a) the occurrence of a Business Combination, (b) the
      declaration of Holder upon the occurrence of an Event of Default as provided
      in
      Section 7.2 hereof, (c) the second anniversary of the Registration Statement
      and
      (d) three (3) years from the date hereof.

     

    
      
        
        

      

      
        1

        
          

        

      

      
        
        

      

    

     

    1.2 Each
      Lender’s obligation to make advances shall expire, and all Obligations shall be
      payable, on the Termination Date.

     

    2.    Conditions
      of Advances.
      Subject
      to the terms and conditions of this Agreement, upon Borrower having provided
      to
      each Lender reasonable notice of a request (a “Borrowing Request”) for a
      borrowing of Loans hereunder (a “Borrowing”), each Lender shall advance to
      Borrower its Pro Rata Share of such Borrowing, provided that all of the
      following conditions are satisfied:

     

    2.1 The
      Borrowing Request shall be in writing and shall provide (i) the amount of the
      Borrowing, (ii) each Lender’s Pro Rata Share of such Borrowing, expressed as
      both a percentage and the amount of the Loan requested to be made by each
      Lender, (iii) the aggregate amount of all Borrowings made hereunder, taking
      into
      effect the Loans to be made pursuant to the current Borrowing Request, (iv)
      the
      aggregate amount of all Loans owing to each Lender, taking into effect the
      Loans

    3.    Borrower
      Representations

     

    3.1 Borrower
      represents and warrants as follows:

     

    3.1.1 Borrower
      has full power and authority to execute and deliver this Agreement and the
      other
      Loan Documents to be executed and delivered by it pursuant hereto and to perform
      its obligations hereunder and thereunder. This Agreement and such Loan Documents
      constitute the valid and legally binding obligations of Borrower and are
      enforceable against Borrower in accordance with their terms.

     

    3.1.2 Neither
      the execution and the delivery of the Loan Documents by Borrower, nor the
      consummation of the transactions contemplated by the Loan Documents, nor the
      borrowing by Borrower, will (a) violate any constitution, statute, regulation,
      rule, injunction, judgment, order, decree, ruling, charge, or other restriction
      of any government, governmental agency, or court to which Borrower is subject
      or
      any provision of the Certificate of Incorporation or Bylaws of Borrower, or
      (b)
      conflict with, result in a breach of, constitute a default under, result in
      the
      acceleration of, create in any entity or natural person (each, a “Person”)
      the
      right to accelerate, terminate, modify, or cancel, any agreement, contract,
      lease, license, instrument, or other arrangement to which Borrower is a party
      or
      by which it is bound or to which any of its assets are subject (or result in
      the
      imposition of any security interest upon any of its assets), in each case other
      than where such violation, conflict, breach, default, acceleration or creation
      of right would not reasonably be expected to have a material adverse effect
      on
      the ability of Borrower to repay amounts due under the Notes in accordance
      with
      the terms of the Loan Documents (a “Material
      Adverse Effect”).

     

    3.1.3 Borrower
      does not need to give any notice to, make any filing with, or obtain any
      authorization, permit, certificate, registration, consent, approval or order
      of
      any government or governmental agency in order for the parties to consummate
      the
      transactions contemplated by this Agreement, except where the failure would
      not
      reasonably be expected to have a Material Adverse Effect.

     

    3.1.4 The
      conditions to the obligation of the Lenders to make Loans, as set forth in
      Section 2, shall be satisfied.

     

    3.2 Each
      and
      every representation and warranty made by Borrower in this Agreement shall
      be
      deemed renewed and remade upon the making of each and every Loan or to the
      extent such representation or warranty expressly relates to an earlier date
      on
      and as of such earlier date..

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    4.    Borrower
      Covenants.
      For as
      long as the Lenders shall have a commitment to make Loans or there shall be
      any
      outstanding Obligations, Borrower shall:

     

    4.1 use
      the
      proceeds only for (a) prior to the closing of the Public Offering, costs and
      expenses of the Public Offering, including legal, accounting, printing and
“road
      show” expenses; and (b) after the closing of the Public Offering, ordinary and
      reasonable operating costs and expenses during the period Borrower seeks to
      identify, investigate, negotiate and consummate a Business Combination,
      including Borrower’s reporting obligations with the SEC, the audit and review of
      Borrower’s financial statements, identifying and investigating potential targets
      for a Business Combination, negotiating and closing the Business Combination,
      legal and other professional fees and expenses, fees, salaries and compensation
      for directors, officers, employees, consultants and advisors, and insurance
      premiums;

     

    4.2 within
      fifteen days following the closing of the Public Offering, pay all Obligations
      hereunder;

     

    4.3 not
      declare or pay any dividend or distribution with respect to, or repurchase
      or
      redeem any shares of, the capital stock of Borrower, provided that this shall
      not prohibit payments from the Trust Account to stockholders of Borrower in
      accordance with the Trust Agreement;

     

    4.4 not
      engage in any business other than consummating its Public Offering and
      identifying, investigating, negotiating and closing a Business
      Combination;

     

    4.5 not
      make
      any material capital expenditure or purchase any material property or asset
      (other than office supplies and equipment); and 

     

    4.6 upon
      request of a Lender, provide to such Lender copies of all filings with the
      SEC.

     

    5.    No
      Recourse to Trust Account

     

    Each
      Lender, on behalf of itself and its successors and assigns, hereby acknowledges
      and agrees that under no circumstance shall it have any right, title or interest
      in or to any of the funds in the Trust Account, notwithstanding the fact that
      such funds were received for the purchase and sale of securities of Borrower,
      or
      any funds distributed from the Trust Account to Borrower’s stockholders, and
      that its sole recourse for repayment of any and all amounts due hereunder and
      under the Note issued to it shall be against the assets or properties of
      Borrower never deposited into the Trust Account or distributed to Borrower
      from
      the Trust Account. Each Lender hereby irrevocably waives any claim that it
      might
      have to funds in the Trust Account, at law or in equity, and agrees not to
      make
      any such claim, and agrees to indemnify and hold Borrower harmless from any
      such
      claim made by or on behalf of such Lender.

     

    6.    Events
      of Default.
      The
      occurrence of any of the following shall constitute an event of default (an
      “Event
      of Default”)
      hereunder and under each and every other Loan Document:

     

    6.1 Borrower
      shall fail to pay any principal, interest or any other Obligation as and when
      due and payable under any Loan Document;

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

     

    6.2 Any
      representation or warranty which is made or deemed made in any Loan Document
      by
      Borrower shall prove to have been incorrect or misleading in any material
      respect on or as of the date made or deemed made or remade;

     

    6.3 Borrower
      shall fail to perform or observe any term, provision, covenant, or agreement
      contained in any Loan Document to be performed or observed by Borrower (other
      than any payment obligation) and such failure shall continue more than 20 days
      after notice thereof from any Lender;

     

    6.4 Borrower
      shall (a) generally not, or be unable to, or admit in writing its inability
      to,
      pay its debts as such debts become due; or (b) make an assignment for the
      benefit of creditors, or petition or apply to any tribunal for the appointment
      of a custodian, receiver, or trustee for it or a substantial part of its assets;
      or (c) commence any proceeding under any bankruptcy, reorganization,
      arrangement, readjustment of debt, dissolution, or liquidation law or statute
      of
      any jurisdiction, whether now or hereafter in effect; or (d) have any such
      petition or application filed or any such proceeding commenced against it in
      which an order for relief is entered or adjudication or appointment is made
      and
      which remains undismissed for a period of 30 days or more; or (e) by any act
      or
      omission to act indicate consent to, approval of, or acquiescence in any such
      petition, application, or proceeding, or order for relief, or the appointment
      of
      a custodian, receiver, or trustee for all or any such substantial part of its
      properties; or (f) suffer any such custodianship, receivership, or trusteeship
      for all or any substantial part of its properties; or (g) suffer any such
      custodianship, receivership, or trusteeship to continue undischarged for a
      period of 30 days or more;

     

    6.5 At
      any
      time after execution and delivery of this Agreement, and for any reason at
      no
      fault of any Lender, any Loan Document shall cease to be in full force and
      effect and enforceable in accordance with its terms, or shall be declared null
      and void; or

     

    6.6 The
      adoption of a resolution by the Board of Directors of Borrower authorizing
      or
      approving the dissolution and/or liquidation of Borrower.

     

    7.    Consequences
      of Default.
      If an
      Event of Default shall occur, each Lender:

     

    7.1 shall
      have no further obligation to make Loans; and

     

    7.2 may
      declare its Note, all interest thereon, and all other amounts payable under
      this
      Agreement and any other Loan Document to be forthwith due and payable, whereupon
      the Note, all such interest, and all such amounts shall become and be forthwith
      due and payable, without presentment, demand, protest, or further notice of
      any
      kind, all of which are hereby expressly waived by Borrower, provided, however,
      upon the occurrence of any Event of Default set forth in
      Section 6.4, the Note, all such interest and all such other amounts shall
      automatically become due and payable without any action on the part of
      Lender.

      Provisions

              name
                on signature pages to this
                Agreement

            

    

     

    Any
      notice shall be effective and be deemed to have been received (i) if delivered
      by hand, upon personal delivery, (ii) if delivered by overnight courier service,
      one business day after delivery to such courier service, (iii) if delivered

      to time change its address for further Notices hereunder by giving notice to
      the
      other party in the manner prescribed in this Section.

     

    8.2 No
      Waivers; Remedies Cumulative.
      No
      failure or delay by a party in exercising any right, power or privilege
      hereunder shall operate as a waiver thereof, nor shall any single or partial
      exercise thereof preclude any other or further exercise thereof or the exercise
      of any other right, power or privilege. The rights and remedies provided herein
      shall be cumulative and not exclusive of any rights or remedies provided by
      law.

     

    8.3 Successors
      and Assigns of Borrower.
      Borrower may not assign its right or duties hereunder without the prior written
      consent of each Lender, which consent each Lender may deny, withhold or delay
      in
      its sole and absolute discretion.

     

    8.4 Assignments;
      Participations by Lenders.
      Each
      Lender may assign and delegate to one or more Persons (each, an “Assignee”) all
      or any part of the Obligations, the Commitments and the other rights and
      obligations of such Lender hereunder and under the other Loan Documents. Upon
      consummation of the assignment, (i) the Assignee shall be a party hereto and
      shall have the rights and obligations of a Lender hereunder and under the other
      Loan Documents, (ii) the assignor Lender shall, to the extent that rights and
      obligations hereunder and under the other Loan Documents have been assigned
      by
      it, relinquish its rights and be released from its obligations under this
      Agreement, and (iii) this Agreement shall be deemed to be amended to the extent,
      but only to the extent, necessary to reflect the addition of the Assignee and
      the resulting adjustment of the Commitments arising therefrom. The Commitment
      allocated to each Assignee shall reduce such Commitment of the assigning Lender
      pro tanto. Each Lender may from time to time sell or otherwise grant
      participations in any Obligations and the other interests of that Lender
      hereunder and under any of the other Loan Documents. Borrower agrees that each
      such holder may exercise any and all rights of banker’s lien, set-off and
      counterclaim with respect to its participation in the Obligations as fully
      as
      though such Borrower were directly indebted to such holder in the amount of
      such
      participation.

      Law.
      This
      Agreement and the other Loan Documents shall be construed in accordance with
      the
      laws of the State of New York without giving effect to the principles of
      conflicts of law thereof. Any legal action or proceeding with respect to any
      Loan Document may be brought in the courts of the State of New York located
      in
      the City of New York, Borough of Manhattan, or of the United States of America
      for the Southern District of New York and, by execution and delivery of this
      Agreement, Borrower hereby accepts for itself and in respect of its property,
      generally and unconditionally, the jurisdiction of the aforesaid courts. The
      parties hereto hereby irrevocably waive any objection, including any objection
      to the laying of venue or based on the grounds of forum non conveniens, that
      any
      of them may now or hereafter have to the bringing of any such action or
      proceeding in such jurisdictions.

     

    8.6 Service
      of Process.
      Borrower hereby irrevocably waives personal service of any and all legal
      process, summons, notices and other documents and other service of process
      of
      any kind and consents to such service in any suit, action or proceeding brought
      in the United States of America with respect to or otherwise arising out of
      or
      in connection with any Loan Document by any means permitted by applicable
      requirements of law, including by the mailing thereof (by registered or
      certified mail, postage prepaid) to the address of Borrower specified in Section
      8.1 (and shall be effective when such mailing shall be effective, as provided
      therein). Borrower agrees that a final judgment in any such action or proceeding
      shall be conclusive and may be enforced in other jurisdictions by suit on the
      judgment or in any other manner provided by law. Nothing contained in this
      Section 8.7 shall affect the right of any Lender to serve process in any other
      manner permitted by applicable requirements of law or commence legal proceedings
      or otherwise proceed against Borrower in any other jurisdiction.

      ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES
      HERETO HAVE BEEN INDUCED TO ENTER INTO THE LOAN DOCUMENTS, AS APPLICABLE, BY
      THE
      MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.8.

     

    8.8 Prior
      Understandings.
      This
      Agreement supersedes all prior understandings and agreements (whether written,
      oral or otherwise) pertaining to the subject matter hereof, and constitutes
      the
      entire agreement between the parties hereto relating to the subject matter
      hereof and the transactions provided for herein.

     

    8.9 Counterparts.
      This
      Agreement may be executed in any number of counterparts each of which shall
      be
      deemed an original and all of which shall constitute one and the same agreement
      with the same effect as if all parties had signed the same signature page.
      The
      parties shall accept facsimile signatures as the equivalent of original
      ones.

    8.10 Severability.
      If any
      provision of this Agreement or the application of such provision to any Person
      or circumstance will be held invalid, the remainder of this Agreement or the
      application of such provision to Persons or circumstances other than those
      to
      which it is held invalid will not be affected thereby.

     

    8.11 Additional
      Documents and Acts.
      Borrower shall execute and deliver such additional documents and instruments
      and
      shall perform such additional acts as may be necessary or appropriate to
      effectuate, carry out and perform all of the terms, provisions, and conditions
      of this Agreement and the transactions contemplated by this
      Agreement.

     

    8.12 Survival.
      All
      indemnities, rights, remedies, representations and warranties contained herein
      shall survive the expiration or termination of this Agreement, and no
      termination or expiration hereof shall relieve either party from liability
      for
      any breach of this Agreement.

     

    8.13 Payments
      by Borrower.
      All
      payments to be made by Borrower shall be made without set-off, recoupment or
      counterclaim. Except as otherwise expressly provided herein, all payments by
      Borrower shall be made to each Lender, at the account designated by such Lender,
      and shall be made in lawful money of the United States and in immediately
      available funds, no later than 5:00 p.m. (eastern time) on the due date thereof.
      Any payment received later than 5:00 p.m. (eastern time) shall be deemed to
      have
      been received on the following business day and any applicable interest or
      fee
      shall continue to accrue. Whenever any payment is due on a day other than a
      business day, such payment shall be due on the following business day, and
      such
      extension of time shall in such case be included in the computation of interest
      or fees, as the case may be.

     

    8.14 Repayments
      and Prepayments.
      Principal
      and interest payments shall be apportioned ratably among the Lenders and
      payments of any fees and expenses shall, as applicable, be apportioned ratably
      among the Lenders. All payments shall be remitted directly to each Lender.
      All
      such payments not relating to principal or interest of specific Loans, or not
      constituting payment of specific fees and expenses, shall be applied, ratably,
      subject to the provisions of this Agreement, first, to pay any fees or expense
      reimbursements then due to the Lenders from Borrower; second to interest due
      in
      respect of all Loans; third, to pay or prepay principal of the Loans and fourth,
      to the payment of any other Obligation due to any Lender by Borrower. The
      Lenders shall have the continuing and exclusive right to apply and reverse
      and
      reapply any and all such payments to any portion of the
      Obligations.

     

    8.15 Indemnity
      for Returned Payments.
      If
      after receipt of any payment which is applied to the payment of all or any
      part
      of the Obligations, any Lender is for any reason compelled to surrender such
      payment because such payment is invalidated, declared fraudulent, set aside,
      determined to be void or voidable as a preference, impermissible setoff, or
      a
      diversion of trust funds, or for any other reason, then the Obligations or
      part
      thereof intended to be satisfied shall be revived and continued and this
      Agreement shall continue in full force as if such payment or proceeds had not
      been received by such Lender and Borrower shall be liable to pay to such Lender,
      and hereby does indemnify each Lender and hold each Lender harmless for the
      amount of such payment surrendered. The provisions of this Section 8.14
      shall be and remain effective notwithstanding any contrary action which may
      have
      been taken by any Lender in reliance upon such payment, and any such contrary
      action so taken shall be without prejudice to the Lenders’ rights under this
      Agreement and shall be deemed to have been conditioned upon such payment having
      become final and irrevocable. The provisions of this Section 8.14 shall
      survive the termination of this Agreement.

    8.16
      Setoff;
      Sharing of Payments.

     

    8.16.1 Each
      Lender is hereby authorized, without notice or demand (each of which is hereby
      waived by Borrower), at any time and from time to time during the continuance
      of
      any Event of Default and to the fullest extent permitted by applicable
      requirements of law, to set off and apply any and all deposits (whether general
      or special, time or demand, provisional or final) at any time held and other
      indebtedness, claims or other obligations at any time owing by such Lender
      to or
      for the credit or the account of Borrower against any Obligation now or
      hereafter existing, whether or not any demand was made under any Loan Document
      with respect to such Obligation and even though such Obligation may be
      unmatured. Each Lender agrees promptly to notify Borrower and each other Lender
      after any such setoff and application made by such Lender; provided,
      however,
      that
      the failure to give such notice shall not affect the validity of such setoff
      and
      application. The rights under this Section
      8.17.1
      are in
      addition to any other rights and remedies (including other rights of setoff)
      that the Lenders may have.

     

    8.16.2 If
      any
      Lender obtains any payment of any Obligation (whether voluntary, involuntary
      or
      through the exercise of any right of setoff) and such payment exceeds the amount
      such Lender would have been entitled to receive if all payments had gone to,
      and
      been distributed in accordance with the provisions of the Loan Documents, such
      Lender shall purchase for cash from other Lenders such participations in their
      Obligations as necessary for such Lender to share such excess payment with
      such
      other Lenders to ensure such payment is applied as though it had been received
      by each Lender and applied in accordance with this Agreement; provided,
      however,
      that
      (a) if such payment is rescinded or otherwise recovered from such Lender, in
      whole or in part, such purchase shall be rescinded and the purchase price
      therefor shall be returned to such Lender without interest and (b) such Lender
      shall, to the fullest extent permitted by applicable requirements of law, be
      able to exercise all its rights of payment (including the right of setoff)
      with
      respect to such participation as fully as if such Lender were the direct
      creditor of Borrower in the amount of such participation.

     

    8.17 Relation
      Among Lenders.
      The
      Lenders are not partners or co-venturers, and no Lender shall be liable for
      the
      acts or omissions of, or authorized to act for, any other Lender.

     

    8.18 Lenders’
      Failure to Perform.
      All
      Loans shall be made by the Lenders simultaneously and in accordance with their
      Pro Rata Shares. It is understood that (i) no Lender shall be responsible for
      any failure by any other Lender to perform its obligation to make any Loans
      hereunder, nor shall any Commitment of any Lender be increased or decreased
      as a
      result of any failure by any other Lender to perform its obligation to make
      any
      Loans hereunder, (ii) no failure by any Lender to perform its obligation to
      make
      any Loans hereunder shall excuse any other Lender from its obligation to make
      any Loans hereunder and (iii) the obligations of each Lender hereunder shall
      be
      several, not joint and several.

    REVOLVING
      LINE OF CREDIT NOTE

    August
      14, 2007

     

    Not
      to Exceed $210,000 in Principal 

     

    For
      value
      received, the undersigned HAMBRECHT ASIA ACQUISITION CORP., a Delaware
      corporation (“Borrower”),
      promises to pay, in lawful money of the United States, to the order of Robert
      Eu, together with his successors and assigns (“Holder”),
      at
      such address as Holder may direct, the principal sum of Two Hundred Ten Thousand
      Dollars ($210,000) (the “Commitment
      Amount”),
      or so
      much thereof as shall have been advanced and shall remain unpaid hereunder,
      together with interest from date of disbursement at the rate of 4% per annum
      (the “Interest
      Rate”).
      Interest shall be computed at the Interest Rate on the basis of the actual
      number of days during which the principal balance is outstanding, divided by
      365, which shall, for interest computation purposes, be considered one year.
      Notwithstanding anything to the contrary expressed or implied herein, all
      payments made by Borrower hereunder (including, without limitation, any
      prepayments) shall be applied first to pay any fees or expense reimbursement
      then due Holder, second to accrued and unpaid interest due under this Note
      and
      third to the reduction of principal due hereunder.

     

    This
      Note
      is delivered pursuant to, and is subject to all of the terms and conditions
      of,
      that certain Revolving Line of Credit Agreement dated August 14, 2007 (as from
      time to time amended, modified, supplemented and restated, the “Loan
      Agreement”)
      among
      Borrower and Holder. Unless otherwise defined in this Note, capitalized terms
      used in this Note shall have the meanings ascribed to them in the Loan
      Agreement, and in the event of any conflict between the terms of this Note
      and
      the terms of the Loan Agreement, the terms of the Loan Agreement shall
      govern.

     

    Maturity.
      This
      Note shall mature and become due and payable on the Termination
      Date.

     

    Prepayment. Borrower
      may prepay Loans at any time, and reborrow subject to the terms of the Loan
      Agreement.

     

    Event
      of Default.
      Should
      an Event of Default (as defined in the Loan Agreement) occur, Lender shall
      have
      the rights set forth in Section 7 of the Loan Agreement.

     

    Borrower’s
      Acknowledgement.
      Borrower
      acknowledges that Holder is extending the credit contemplated hereby solely
      as
      an accommodation to Borrower, and is willing to do so in reliance upon
      Borrower’s monetary and non-monetary covenants contained herein and in the Loan
      Agreement.

     

    Holder’s
      Acknowledgement.
      The
      Holder acknowledges and agrees that, as specified in Section 5 of the Loan
      Agreement, the Holder has limited recourse against Borrower for repayment of
      any
      and all amounts due and owing under this Note.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    Miscellaneous.
      If this
      Note (or any payment due hereunder) is not paid when due, Borrower promises
      to
      pay all costs and expenses of collection and reasonable attorneys’ fees incurred
      by the
      Holder hereof on account of such collection, plus interest at the rate
      applicable to principal, whether or not suit is filed hereon. Borrower consents
      to renewals, replacements and extensions of time for payment hereof, before,
      at,
      or after maturity, consents to the acceptance, release or substitution of
      security for this Note, and waives demand and protest. The indebtedness
      evidenced hereby shall be payable in lawful money of the United States of
      America. In any action brought under or arising out of this Note and the other
      Loan Documents, Borrower, including successor(s) or assign(s), hereby consents
      to the application of New York law. No single or partial exercise of any power
      hereunder, or under any other Loan Document in connection herewith, shall
      preclude other or further exercises thereof or the exercise of any other such
      power.

     

    IN
      WITNESS WHEREOF, Borrower has executed and delivered this Note as of the date
      first above written.
