    2.1.           Demand
      Registration.

     

    2.1.1                      Request
      for Registration.  At any time commencing ninety (90) days prior
      to, and from time to time on or after a Release Date, the Investor or, if the
      Investor does not own any Registrable Securities, holders of at least 50.1%
      of
      the Registrable Securities, on an as-converted to Common Stock basis, may make
      a
      written demand for registration under the Securities Act of all or part of
      the
      related 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 in writing 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
      three (3) 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 material 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, (a) such
      stop order or injunction is removed, rescinded or otherwise terminated, and
      (b)
      a majority-in-interest of the Demanding Holders thereafter elects 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.

    
       

      
        
          
          

        

        
          3

          
            

          

        

        
          
          

        

      

    2.1.3                      Underwritten
      Offering.  If a majority-in-interest of the Demanding Holders so
      elects 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 advise(s) 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: (a) 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 Holders
      have 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; (b) second, to the extent that the Maximum Number of Shares
      has not been reached under the foregoing clause (a), 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; (c) third, to the extent that the
      Maximum Number of Shares has not been reached under the foregoing clauses (a)
      and (b), 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; and (d) fourth, to the extent that
      the
      Maximum Number of Shares have not been reached under the foregoing clauses
      (a),
      (b) and (c), the shares of Common Stock that other shareholders desire to sell
      that can be sold without exceeding the Maximum Number of Shares to the extent
      that the Company, in its sole discretion, wishes to permit such sales pursuant
      to this clause (d).

     

    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 Section 2.1, provided that the
      majority-in-interest of the Demanding Holders electing to so withdraw from
      the
      offering pays all costs and expenses incurred by the Company in connection
      with
      such withdrawn Demand Registration.

    
           

       

      
        2.1.6      
Permitted
          Delays.  The Company shall be entitled to postpone the filing of any
          Registration Statement under this Section 2.1 (a) until the applicable
          Release
          Date, or (b) for up to sixty (60) days, if (i) at any time prior to the
          filing
          of such Registration Statement the Company’s Board of Directors determines, in
          its good faith business judgment, that such registration and offering would
          materially and adversely affect any financing, acquisition, corporate
          reorganization, or other material transaction involving the Company, and
          (ii)
          the Company delivers to the Demanding Holders written notice thereof within
          five
          (5) business days of the date of receipt of such request for Demand
          Registration.

    2.2.           Piggy-Back
      Registration.

     

    2.2.1                      Piggy-Back
      Rights.  If at any time on or after a 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 stockholders of the Company for their account
      (or by the Company and by stockholders of the Company including, without
      limitation, pursuant to Section 2.1), then the Company
      shall (a) 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 (b) 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 ten (10) 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
      commercially reasonable 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.

     

    2.2.2                      Reduction
      of Offering.  If the managing Underwriter or Underwriters for a
      Piggy-Back Registration that is to be an underwritten offering advise(s) 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 2.2, 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:

     

    (a)        If

    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 (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
      without thereby incurring any liability to the holders of Registrable
      Securities. 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.

     

    2.2.4                      Permitted
      Delays.  The Company shall be entitled to postpone, for up to
      sixty (60) days (but not for more than one hundred eighty (180) days in any
      calendar year), the filing of any Registration Statement under this Section
      2.2,
      if (a) at any time prior to the filing of such Registration Statement the
      Company’s Board of Directors determines, in its good faith business judgment,
      that such registration and offering would materially and adversely affect any
      financing, acquisition, corporate reorganization, or other material transaction
      involving the Company, and (b) the Company delivers to the holder of Registrable
      Securities requesting a Piggy-Back Registration written notice thereof within
      five (5) business days of the date of receipt by the Company of such request
      for
      Piggy-Back Registration.

     

    2.3.           Registrations
      on Form S-3.  At any time on or after a Release Date, 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 S-3 or any similar short-form registration which may be
      available at such time (“Form S-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:
      (a)
      if Form S-3 is not available for such offering; or (b) 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.

                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 commercially reasonable 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 commercially reasonable efforts to cause such Registration
      Statement to become and remain effective for the period required by Section
      3.1.3; provided, however, 

    
      
        
        

      

      
        6

        
          

        

      

      
        
        

      

    

     

    
      that
        the
        Company shall have the right to defer any Demand Registration for up to sixty
        (60) 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 or Chairman of the Company stating
        that,
        in the good faith judgment of the Board, it would be materially detrimental
        to
        the Company and its stockholders for such Registration Statement to be effected
        at such time; provided, further, that the
        Company shall not have
        the
        right to exercise the right set forth in the immediately preceding proviso
        more
        than once in any three hundred sixty five (365) day period in respect of
        a
        Demand Registration hereunder.

    

     

    3.1.2                      Copies.  The
      Company shall, prior to filing a Registration Statement or prospectus, or any
      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.

     

    3.1.4                      Notification.  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 within two (2) business days of the
      occurrence of any of the following: (a) when such Registration Statement becomes
      effective; (b) when any post-effective amendment to such Registration Statement
      becomes effective; (c) the issuance or threatened issuance by the Commission
      of
      any stop order (and the Company shall take all commercially reasonable actions
      required to prevent the entry of such stop order or to remove it if entered);
      and (d) any request by the Commission 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 commercially
      reasonable efforts to (a) 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 (b) take such action necessary to cause such
      Registrable Securities covered by the

        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 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.

      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

      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.

      period of twelve (12) months, beginning within three (3) months after the
      effective date of the registration statement, which earnings statement shall

      thereunder.

      Company shall use commercially reasonable 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

        the
        case of a resale registration on Form S-3 pursuant
        to Section 2.3 hereof, upon any suspension by the Company, pursuant to a
        written
        insider trading compliance program adopted by the Board, 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(d)
        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

      (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
      in
      connection with the listing of the Registrable Securities as required by Section
      3.1.11; (vi) Financial Industry Regulatory Authority fees; (vii) fees and
      disbursements of counsel for the Company and fees and expenses for independent

      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 (1) legal counsel selected by the holders of a

      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 stockholders 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.

      the 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 (within the meaning
      of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) an
      Investor and each other holder of Registrable Securities (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

      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.

    

     

    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
      selling holder and each other Person, if any, who controls another selling
      holder 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 other selling holder or 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.

     

    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.

     

    4.4.3                      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.

    5.1.           Rule
      144.  The Company covenants that it shall file any 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 Securities without registration under the Securities
      Act within the limitation of the exemptions provided by Rule 144 under the
      Securities Act, as such Rules may be amended from time to time, or any similar
      Rule or regulation hereafter adopted by the Commission.

    6.1.           Other
      Registration Rights.  The Company represents and warrants that no
      Person, other than a holder of the Registrable Securities, has any right to
      require the Company to register any shares of the Company’s capital stock for
      sale or to include shares of the Company’s capital stock in any registration
      filed by the Company for the sale of shares of capital stock for its own account
      or for the account of any other Person.

     

    6.2.           Assignment;
      No Third Party Beneficiaries.  This Agreement and the rights,
      duties and obligations of the Company hereunder may not be assigned or delegated
      by the Company in whole or in part. This Agreement and the rights, duties and
      obligations of the holders of Registrable Securities hereunder may be freely
      assigned or delegated by such holder of Registrable Securities in conjunction
      with and to the extent of any transfer of Registrable Securities held by any
      such holder. This Agreement and the provisions hereof shall be binding upon
      and
      shall inure to the benefit of each of the parties hereto and their respective
      permitted successors and assigns. Except as otherwise expressly set forth
      herein, this Agreement is not intended to confer any rights or benefits on
      any
      Persons that are not party hereto other than as expressly set forth in Article
      4
      and this Section 6.2.

      Agreement shall be deemed severable, and the invalidity or unenforceability
      of
      any term or provision hereof shall not affect the validity or enforceability

      representations, understandings, negotiations and discussions between the

    6.7.           Modifications
      and Amendments.  No amendment, modification or termination of this
      Agreement shall be binding upon any party unless executed in writing by such

    6.8.           Titles
      and Headings.  Titles and headings of sections of this Agreement

      and Extensions.  Any party to this Agreement may waive any right,
      breach or default which such party has the right to waive,
provided that such waiver will not be effective against the
      waiving party unless it is in writing, is signed by such party, and specifically
      refers to this Agreement. Waivers may be made in advance or after the right
      waived has arisen or the breach or default waived has occurred. Any waiver
      may
      be conditional. No waiver of any breach of any agreement or provision herein
      contained shall be deemed a waiver of any preceding or succeeding breach thereof

      a
      waiver or extension of the time for performance of any other obligations or
      acts.

     

    6.10.                      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.

     

    6.11.                      Governing
      Law.  This Agreement shall for all purposes be deemed to be made
      under and shall be construed in accordance with the laws of the State of New
      York, without giving effect to conflicts of law principles that would result
      in
      the application of the substantive laws of another jurisdiction. The parties
      hereto agree that any action, proceeding or claim against it arising out of
      or
      relating in any way to this Agreement shall be brought and enforced in the
      courts of the State of New York or the United States District Court for the
      Southern District of New York, and irrevocably submit to such jurisdiction,
      which jurisdiction shall be exclusive. The parties hereby waive any objection
      to
      such exclusive jurisdiction and that such courts represent an inconvenient
      forum.

     

    6.12.                      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 any Investor in the negotiation,
      administration, performance or enforcement hereof.

    PLACEMENT WARRANT
      PURCHASE AGREEMENT

     

    THIS
      PLACEMENT WARRANT PURCHASE AGREEMENT (the
“Agreement”) made as of this [●]
      day of [●],
      2007, among NRDC Acquisition Corp., a Delaware corporation (the
“Company”), and NRDC Capital Management, LLC,
      a Delaware limited liability company (the
“Purchaser”).

     

    WHEREAS,
      the Company intends to file with the Securities and Exchange Commission
      (“SEC”) a registration statement on Form S-1 (the
“Registration Statement”), in connection with the Company’s
      initial public offering (the “IPO”) of up to 34,500,000 units
      (including 4,500,000 additional units subject to the underwriters’
over-allotment option), each unit consisting of one share of the Company’s
      common stock, $.0001 par value (the “Common Stock”), and
      (ii) one warrant, each warrant to purchase one share of Common Stock at an
      exercise price of $7.50 per share;

     

    WHEREAS,
      the Company desires to sell to the Purchaser, in a private placement, 8,000,000
      warrants (the “Warrants”) substantially identical to the
      warrants being issued in the IPO pursuant to the terms and conditions hereof
      and
      as set forth in the Registration Statement, except that the Warrants
      (i) may be exercised on a cashless basis so long as they are held by the
      Purchaser, its members, members of its members’ immediate families or their
      controlled affiliates, and (ii) may not be sold or transferred, except in
      limited circumstances, until after the consummation of the Company’s Business
      Combination (as defined below);

     

    WHEREAS,
      the Warrants shall be governed by the Warrant Agreement filed as an exhibit
      to
      the Registration Statement; and

     

    WHEREAS,
      the Purchaser is entitled to registration rights with respect to the Warrants
      and the Common Stock underlying the Warrants on the terms set forth in this
      Agreement.

     

    NOW,
      THEREFORE, for and in consideration of the premises and the mutual covenants
      hereinafter set forth, the parties hereto do hereby agree as
      follows:

     

    1.  Purchase
      of Warrants. The Purchaser agrees to purchase from the Company, and the
      Company agrees to sell to the Purchaser, the Warrants at a purchase price of
      $1.00 per Warrant (the “Purchase Price”). The Company and the
      Purchaser agree and acknowledge that the sale by the Company, and the purchase
      and receipt by the Purchaser, of the Warrants pursuant to this Agreement will
      equal (a) an aggregate issuance of 8,000,000 Warrants, and (b) an
      aggregate Purchase Price of $8,000,000.

     

    2.  Closing.
      The closing of the purchase and sale of the Warrants (the
“Closing”) will take place at such time and place as the
      parties may agree, but in any event prior to the completion of the
      IPO (the “Closing Date”). On the Closing Date, the
      Purchaser shall pay the Purchase Price by wire transfer of funds to an account
      maintained by the Company. Immediately prior to the closing of the IPO, the
      Company shall deposit the Purchase Price into the trust account described in
      the
      Registration Statement. The certificates for the Warrants shall be delivered
      to
      the Purchaser promptly after the closing of the IPO.

     

    3.  Lock-Up
      Agreement.

     

    3.1  At
      or
      prior to the Closing, the Purchaser shall enter into a lock-up agreement with
      the representative of the underwriters of the Company’s IPO, Banc of America
      Securities LLC, pursuant to which the Purchaser shall agree to not to sell
      the
      Purchaser’s Warrants until after the consummation of the Company’s Business
      Combination (the “Lock-Up Period”). Such Lock-Up Period will be
      extended for up to 18 days if (i) during the last 17 days of the Lock-Up Period
      the Company issues material news or a material event relating to the Company
      occurs or (ii) before the expiration of the applicable Lock-Up Period the
      Company announces that material news or a material event will occur during
      the
      16-day period beginning on the last day of the applicable Lock-Up
      Period.  For purposes of this Agreement, “Business
      Combination” shall mean the Company’s initial acquisition of one or
      more operating businesses through a merger, capital stock exchange, stock
      purchase, asset

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    acquisition
      or other similar business combination which will require that a majority of
      the
      Company’s shares of common stock voted by the Company’s public stockholders (as
      described in the Registration Statement) are voted in favor of the acquisition
      and less than 30% of the Company’s public stockholders both vote against the
      proposed acquisition and exercise their conversion rights (as described in
      the
      Registration Statement).

     

    3.2  Notwithstanding
      Section 3.1 above, during the Lock-Up Period, the Purchaser shall
      nevertheless have the right to transfer the Purchaser’s Warrants and the shares
      issuable upon the exercise of the Purchaser’s Warrants (a) to members or
      former members, members of their immediate families or their controlled
      affiliates (each, a “Permitted Transferee”), (b) to a
      trust, the beneficiary of which is a member of the immediate family of a
      Permitted Transferee, (c) by virtue of the laws of descent and distribution
      upon death of a Permitted Transferee, (d) to other officers and/or
      directors of the Company, (e) pursuant to a qualified domestic relations
      order, or (f) in the event of the Company’s dissolution prior to the
      Business Combination or the consummation of a liquidation, merger, capital
      stock
      exchange, stock purchase, asset acquisition or other similar transaction which
      results in all of the Company’s stockholders having the right to exchange their
      shares of Common Stock for cash, securities or other property subsequent to
      the
      Company consummating a Business Combination; provided, however, that,
      in connection with each proposed transfer, no such transfer shall be effective
      unless and until the transferee has agreed in writing: (i) to be subject to
      the transfer restrictions set forth in this Section 3, (ii) to waive
      such transferee’s right to participate in any liquidation distribution with
      respect to all shares owned by the transferring Purchaser prior to the IPO
      (but
      not shares acquired in the IPO or in the secondary market) if the Company fails
      to consummate a Business Combination, (iii) to waive such transferee’s
      right to conversion in connection with the Company’s Business Combination,
      (iv) to vote with respect to all shares owned by the transferring Purchaser
      prior to the IPO (but not shares acquired in the IPO or in the secondary market)
      with the majority of public stockholders who vote in connection with the
      Company’s Business Combination, and (v) to vote in favor of an amendment to the
      Company’s Amended and Restated Certificate of Incorporation to provide for the
      Company’s perpetual existence.

     

    4.  Representations
      and Warranties of the Purchaser. The Purchaser hereby represents and
      warrants to the Company that:

     

    4.1  The
      Purchaser is an “accredited investor” as that term is defined in Rule 501 of
      Regulation D promulgated under the Securities Act of 1933, as amended (the
      “Securities Act”).

     

    4.2  The
      Warrants (and the shares issuable upon exercise thereof) are being acquired
      for
      the Purchaser’s own account, only for investment purposes and not with a view
      to, or for resale in connection with, any distribution or public offering
      thereof within the meaning of the Securities Act.

     

    4.3  The
      Purchaser has the full right, power and authority to enter into this Agreement
      and this Agreement is a valid and legally binding obligation of the Purchaser
      enforceable against the Purchaser in accordance with its terms.

     

    4.4  The
      Purchaser acknowledges that the Warrants (and the shares issuable upon exercise
      thereof) will bear a legend in substantially the following form:

     

    “THE
      SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE PROVISIONS OF ANY APPLICABLE
      STATE SECURITIES LAWS. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
      HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE
      SECURITIES UNDER SAID ACT AND LAWS OR AN OPINION OF COUNSEL SATISFACTORY TO
      THE
      COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.”

     

    5.  Registration
      Rights Agreement. At or prior to the Closing, the Company and the Purchaser
      shall enter into a mutually satisfactory registration rights agreement having
      the terms described in the Registration Statement.

    
 

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    6.  Waiver
      of Claims; Indemnification. The Purchaser hereby waives any and all rights
      to assert any present or future claims, including any right of rescission,
      against the Company or Banc of America Securities LLC with respect to the
      Purchaser’s purchase of the Warrants, and the Purchaser agrees to indemnify and
      hold the Company and Banc of America Securities LLC harmless from all losses,
      damages or expenses that relate to claims or proceedings brought against the
      Company or Banc of America Securities LLC by any of the Purchaser’s transferees,
      heirs, successors, assigns or any subsequent holders of the Warrants or
      underlying securities.

     

    7.  Counterparts;
      Facsimile. This Agreement may be executed in any number of counterparts,
      each of which when so executed shall be deemed to be an original and all of
      which taken together shall constitute one and the same instrument. This
      Agreement or any counterpart may be executed via facsimile transmission, and
      any
      such executed facsimile copy shall be treated as an original.

     

    8.  Governing
      Law. This Agreement shall for all purposes be deemed to be made under and
      shall be construed in accordance with the laws of the State of New York. Each
      of
      the parties hereby agrees that any action, proceeding or claim against it
      arising out of or relating in any way to this Agreement shall be brought and
      enforced in the courts of the State of New York or the United States District
      Court for the Southern District of New York, and irrevocably submits to such
      jurisdiction, which jurisdiction shall be exclusive. Each of the parties hereby
      waives any objection to such exclusive jurisdiction and that such courts
      represent an inconvenient forum.

     

    9.  Successors
      and Assigns. This Agreement shall be binding upon and inure to the benefit
      of the parties and their successors and assigns, provided,
however, that the Purchaser shall not have the right to assign any
      of its
      rights hereunder to purchase Warrants to any other person.

     

    10.  Third
      Party Beneficiaries. This Agreement is intended for the benefit of the
      parties hereto and their respective permitted successors and assigns, and is
      not
      for the benefit of, nor may any provision hereof be enforced by, any other
      person; provided that Banc of America Securities LLC, on its own behalf
      and on behalf of the several underwriters in the IPO, shall be a third party
      beneficiary of this Agreement.
