    2.
       Shelf
      Registration

    


    (a) On
      or
      prior to each Filing Date, the Company shall prepare and file with the
      Commission a “Shelf” Registration Statement covering the resale of 130% of the
      Registrable Securities on such Filing Date for an offering to be made on a
      continuous basis pursuant to Rule 415. The Registration Statement shall be
      on
      Form S-3 (except if the Company is not then eligible to register for resale
      the
      Registrable Securities on Form S-3, in which case such registration shall be
      on
      another appropriate form in accordance herewith) and shall contain (unless
      otherwise directed by at least an 85% majority in interest of the Holders)
      substantially the “Plan
      of Distribution”
      attached hereto as Annex
      A.
      Subject
      to the terms of this Agreement, the Company shall use its best efforts to cause
      a Registration Statement to be declared effective under the Securities Act
      as
      promptly as possible after the filing thereof, but in any event prior to the
      applicable Effectiveness Date, and shall use its best efforts to keep such
      Registration Statement continuously effective under the Securities Act until
      all
      Registrable Securities covered by such Registration Statement have been sold,
      or
      may be sold without volume restrictions pursuant to Rule 144(k), as determined
      by the counsel to the Company pursuant to a written opinion letter to such
      effect, addressed and acceptable to the Company’s transfer agent and the
      affected Holders (the “Effectiveness
      Period”).
      The
      Company shall telephonically request effectiveness of a Registration Statement
      as of 5:00 pm Eastern Time on a Trading Day. The Company shall immediately
      notify the Holders via facsimile of the effectiveness of a Registration
      Statement on the same Trading Day that the Company telephonically confirms
      effectiveness with the Commission, which shall be the date requested for
      effectiveness of a Registration Statement. The Company shall, by 9:30 am Eastern
      Time on the Trading Day after the Effective Date (as defined in the Purchase
      Agreement), file a final Prospectus with the Commission as required by Rule
      424.
      Failure to so notify the Holder within 1 Trading Day of such notification of
      effectiveness or failure to file a final Prospectus as aforesaid shall be deemed
      an Event under Section 2(b).

    (b) If:
      (i) a
      Registration Statement is not filed on or prior to its Filing Date (if the
      Company files a Registration Statement without affording the Holders the
      opportunity to review and comment on the same as required by Section 3(a),
      the
      Company shall not be deemed to have satisfied this clause (i)), or (ii) the
      Company fails to file with the Commission a request for acceleration in
      accordance with Rule 461 promulgated under the Securities Act, within five
      Trading Days of the date that the Company is notified (orally or in writing,
      whichever is earlier) by the Commission that a Registration Statement will
      not
      be “reviewed,” or not subject to further review, or (iii) prior to its
      Effectiveness Date, the Company fails to file a pre-effective amendment and
      otherwise respond in writing to comments made by the Commission in respect
      of
      such Registration Statement within 10 calendar days after the receipt of
      comments by or notice from the Commission that such amendment is required in
      order for a Registration Statement to be declared effective, or (iv) a
      Registration Statement filed or required to be filed hereunder is not declared
      effective by the Commission by its Effectiveness Date, or (v) after the
      Effectiveness Date, a Registration Statement ceases for any reason to remain
      continuously effective as to all Registrable Securities for which it is required
      to be effective, or the Holders are otherwise not permitted to utilize the
      Prospectus therein to resell such Registrable Securities for more than 10
      consecutive calendar days or more than an aggregate of 15 calendar days during
      any 12-month period (which need not be consecutive calendar days) (any such
      failure or breach being referred to as an “Event”,
      and
      for purposes of clause (i) or (iv) the date on which such Event occurs, or
      for
      purposes of clause (ii) the date on which such five Trading Day period is
      exceeded, or for purposes of clause (iii) the date which such 10 calendar day
      period is exceeded, or for purposes of clause (v) the date on which such 10
      or
      15 calendar day period, as applicable, is exceeded being referred to as
“Event
      Date”),
      then
      in addition to any other rights the Holders may have hereunder or under
      applicable law, on each such Event Date and on each monthly anniversary of
      each
      such Event Date (if the applicable Event shall not have been cured by such
      date)
      until the applicable Event is cured, the Company shall pay to each Holder an
      amount in cash, as partial liquidated damages and not as a penalty, equal to
      2%
      of the aggregate purchase price paid by such Holder pursuant to the Purchase
      Agreement for any Registrable Securities then held by such Holder, up to a
      maximum of 36% per Holder of the aggregate purchase price paid by such Holder
      pursuant to the Purchase Agreement. If the Company fails to pay any partial
      liquidated damages pursuant to this Section in full within seven days after
      the
      date payable, the Company will pay interest thereon at a rate of 18% per annum
      (or such lesser maximum amount that is permitted to be paid by applicable law)
      to the Holder, accruing daily from the date such partial liquidated damages
      are
      due until such amounts, plus all such interest thereon, are paid in full. The
      partial liquidated damages pursuant to the terms hereof shall apply on a daily
      pro-rata basis for any portion of a month prior to the cure of an
      Event.

      Procedures.

    


    In
      connection with the Company’s registration obligations hereunder, the Company

    (a) Not
      less
      than 5 Trading Days prior to the filing of each Registration Statement and
      not
      less than 1 Trading Day prior to the filing of any related Prospectus or any
      amendment or supplement thereto (including any document that would be
      incorporated or deemed to be incorporated therein by reference), the Company
      shall, (i) furnish to each Holder copies of all such documents proposed to
      be
      filed, which documents (other than those incorporated or deemed to be
      incorporated by reference) will be subject to the review of such Holders, and
      (ii) cause its officers and directors, counsel and independent certified public
      accountants to respond to such inquiries as shall be necessary, in the
      reasonable opinion of respective counsel to each Holder to conduct a reasonable
      investigation within the meaning of the Securities Act. The Company shall not
      file a Registration Statement or any such Prospectus or any amendments or
      supplements thereto to which the Holders of a majority of the Registrable
      Securities shall reasonably object in good faith, provided that, the Company
      is
      notified of such objection in writing no later than 5 Trading Days after the
      Holders have been so furnished copies of a Registration Statement or 1 Trading
      Day after the Holders have been so furnished copies of any related Prospectus
      or
      amendment or supplement thereto. Each Holder agrees to furnish to the Company

      Prepare and file with the Commission such amendments, including post-effective
      amendments, to a Registration Statement and the Prospectus used in connection
      therewith as may be necessary to keep a Registration Statement continuously
      effective as to the applicable Registrable Securities for the Effectiveness
      Period and prepare and file with the Commission such additional Registration
      Statements in order to register for resale under the Securities Act all of
      the
      Registrable Securities; (ii) cause the related Prospectus to be amended or
      supplemented by any required Prospectus supplement (subject to the terms of
      this
      Agreement), and as so supplemented or amended to be filed pursuant to Rule
      424;
      (iii) respond as promptly as reasonably possible to any comments received from
      the Commission with respect to a Registration Statement or any amendment thereto
      and as promptly as reasonably possible provide the Holders true and complete
      copies of all correspondence from and to the Commission relating to a
      Registration Statement (provided that the Company may excise any information
      contained therein which would constitute material non-public information as
      to
      any Holder which has not executed a confidentiality agreement with the Company);
      and (iv) comply in all material respects with the provisions of the Securities
      Act and the Exchange Act with respect to the disposition of all Registrable
      Securities covered by a Registration Statement during the applicable period
      in
      accordance (subject to the terms of this Agreement) with the intended methods
      of
      disposition by the Holders thereof set forth in such Registration Statement
      as
      so amended or in such Prospectus as so supplemented.

    



    
      
         

      

      
        6

        
          

        

      

      
         

      

    


    (c) If
      during
      the Effectiveness Period, the number of Registrable Securities at any time
      exceeds 90% of the number of shares of Common Stock then registered in a
      Registration Statement, then the Company shall file as soon as reasonably
      practicable but in any case prior to the applicable Filing Date, an additional
      Registration Statement covering the resale by the Holders of not less than
      130%
      of the number of such Registrable Securities.

    


    (d) Notify
      the Holders of Registrable Securities to be sold (which notice shall, pursuant
      to clauses (iii) through (vi) hereof, be accompanied by an instruction to
      suspend the use of the Prospectus until the requisite changes have been made)
      as
      promptly as reasonably possible (and, in the case of (i)(A) below, not less
      than
      1 Trading Day prior to such filing) and (if requested by any such Person)
      confirm such notice in writing no later than one Trading Day following the
      day
      (i)(A) when a Prospectus or any Prospectus supplement or post-effective
      amendment to a Registration Statement is proposed to be filed; (B) when the
      Commission notifies the Company whether there will be a “review” of such
      Registration Statement and whenever the Commission comments in writing on such
      Registration Statement; and (C) with respect to a Registration Statement or
      any
      post-effective amendment, when the same has become effective; (ii) of any
      request by the Commission or any other Federal or state governmental authority
      for amendments or supplements to a Registration Statement or Prospectus or
      for
      additional information; (iii) of the issuance by the Commission or any other
      federal or state governmental authority of any stop order suspending the
      effectiveness of a Registration Statement covering any or all of the Registrable
      Securities or the initiation of any Proceedings for that purpose; (iv) of the
      receipt by the Company of any notification with respect to the suspension of
      the
      qualification or exemption from qualification of any of the Registrable
      Securities for sale in any jurisdiction, or the initiation or threatening of
      any
      Proceeding for such purpose; (v) of the occurrence of any event or passage
      of
      time that makes the financial statements included in a Registration Statement
      ineligible for inclusion therein or any statement made in a Registration
      Statement or Prospectus or any document incorporated or deemed to be
      incorporated therein by reference untrue in any material respect or that
      requires any revisions to a Registration Statement, Prospectus or other
      documents so that, in the case of a Registration Statement or the Prospectus,
      as
      the case may be, it will not contain any 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, in light of the circumstances under which they
      were
      made, not misleading; and (vi) the occurrence or existence of any pending
      corporate development with respect to the Company that the Company believes
      may
      be material and that, in the determination of the Company, makes it not in
      the
      best interest of the Company to allow continued availability of a Registration
      Statement or Prospectus; provided that any and all of such information shall
      remain confidential to each Holder until such information otherwise becomes
      public, unless disclosure by a Holder is required by law; provided,
      further,
      notwithstanding each Holder’s agreement to keep such information confidential,
      the Holders make no acknowledgement that any such information is material,
      non-public information.

    (e) Use
      its
      best efforts to avoid the issuance of, or, if issued, obtain the withdrawal
      of
      (i) any order suspending the effectiveness of a Registration Statement, or
      (ii)
      any suspension of the qualification (or exemption from qualification) of any
      of
      the Registrable Securities for sale in any jurisdiction, at the earliest
      practicable moment.

    


    (f) Furnish
      to each Holder, without charge, at least one conformed copy of each such
      Registration Statement and each amendment thereto, including financial
      statements and schedules, all documents incorporated or deemed to be
      incorporated therein by reference to the extent requested by such Person, and

      furnished or incorporated by reference) promptly after the filing of such
      documents with the Commission.

      to the terms of this Agreement, the Company hereby consents to the use of such
      Prospectus and each amendment or supplement thereto by each of the selling
      Holders in connection with the offering and sale of the Registrable Securities
      covered by such Prospectus and any amendment or supplement thereto, except
      after
      the giving of any notice pursuant to Section 3(d).

    


    (h) If

      sale
      by a Holder, the Company shall (i) make an Issuer Filing with the NASDR, Inc.
      Corporate Financing Department pursuant to proposed NASDR Rule
      2710(b)(10)(A)(i), (ii) respond within five Trading Days to any comments
      received from NASDR in connection therewith, and (iii) pay the filing fee
      required in connection therewith.

    


    (i) Prior
      to
      any resale of Registrable Securities by a Holder, use its commercially
      reasonable efforts to register or qualify or cooperate with the selling Holders
      in connection with the registration or qualification (or exemption from the
      Registration or qualification) of such Registrable Securities for the resale
      by
      the Holder under the securities or Blue Sky laws of such jurisdictions within
      the United States as any Holder reasonably requests in writing, to keep each
      registration or qualification (or exemption therefrom) effective during the
      Effectiveness Period and to do any and all other acts or things reasonably
      necessary to enable the disposition in such jurisdictions of the Registrable
      Securities covered by each Registration Statement; provided, that the Company
      shall not be required to qualify generally to do business in any jurisdiction
      where it is not then so qualified, subject the Company to any material tax
      in
      any such jurisdiction where it is not then so subject or file a general consent
      to service of process in any such jurisdiction.

    


    (j) If
      requested by the Holders, cooperate with the Holders to facilitate the timely
      preparation and delivery of certificates representing Registrable Securities
      to
      be delivered to a transferee pursuant to a Registration Statement, which
      certificates shall be free, to the extent permitted by the Purchase Agreement,
      of all restrictive legends, and to enable such Registrable Securities to be
      in
      such denominations and registered in such names as any such Holders may
      request.

    (k) Upon
      the
      occurrence of any event contemplated by this Section 3, as promptly as
      reasonably possible under the circumstances taking into account the Company’s
      good faith assessment of any adverse consequences to the Company and its
      stockholders of the premature disclosure of such event, prepare a supplement
      or
      amendment, including a post-effective amendment, to a Registration Statement
      or
      a supplement to the related Prospectus or any document incorporated or deemed
      to
      be incorporated therein by reference, and file any other required document
      so
      that, as thereafter delivered, neither a Registration Statement nor such
      Prospectus will contain an untrue statement of a material fact or omit to state
      a material fact required to be stated therein or necessary to make the
      statements therein, in light of the circumstances under which they were made,
      not misleading. If
      the
      Company notifies the Holders in accordance with clauses (iii) through (vi)
      of
      Section 3(d) above to suspend the use of any Prospectus until the requisite
      changes to such Prospectus have been made, then the Holders shall suspend use
      of
      such Prospectus. The Company will use its best efforts to ensure that the use
      of
      the Prospectus may be resumed as promptly as is practicable. The Company shall
      be entitled to exercise its right under this Section 3(k) to suspend the
      availability of a Registration Statement and Prospectus, subject to the payment
      of partial liquidated damages pursuant to Section 2(b), for a period not to
      exceed 60 calendar days (which need not be consecutive days) in any 12 month
      period.

    


    (l) Comply
      with all applicable rules and regulations of the Commission.

    


    (m) The
      Company may require each selling Holder to furnish to the Company a certified
      statement as to the number of shares of Common Stock beneficially owned by
      such
      Holder and, if required by the Commission, the natural persons thereof that
      have
      voting and dispositive control over the Shares. During any periods that the
      Company is unable to meet its obligations hereunder with respect to the
      registration of the Registrable Securities solely because any Holder fails
      to
      furnish such information within three Trading Days of the Company’s request, any
      liquidated damages that are accruing at such time as to such Holder only shall
      be tolled and any Event that may otherwise occur solely because of such delay
      shall be suspended as to such Holder only, until such information is delivered
      to the Company.

       Registration
      Expenses.
      All
      fees and expenses incident to the performance of or compliance with this
      Agreement by the Company shall be borne by the Company whether or not any
      Registrable Securities are sold pursuant to a Registration Statement. The fees
      and expenses referred to in the foregoing sentence shall include, without
      limitation, (i) all registration and filing fees (including, without limitation,

      disbursements of counsel for the Company in connection with Blue Sky
      qualifications or exemptions of the Registrable Securities) and (C) if not
      previously paid by the Company in connection with an Issuer Filing, with respect
      to any filing that may be required to be made by any broker through which a
      Holder intends to make sales of Registrable Securities with NASD Regulation,
      Inc. pursuant to the NASD Rule 2710, so long as the broker is receiving no
      more
      than a customary brokerage commission in connection with such sale, (ii)
      printing expenses (including, without limitation, expenses of printing
      certificates for Registrable Securities and of printing prospectuses if the
      printing of prospectuses is reasonably requested by the holders of a majority of
      the Registrable Securities included in a Registration Statement), (iii)
      messenger, telephone and delivery expenses, (iv) fees and disbursements of
      counsel for the Company, (v) Securities Act liability insurance, if the Company
      so desires such insurance, and (vi) fees and expenses of all other Persons

      contemplated by this Agreement. In addition, the Company shall be responsible
      for all of its internal expenses incurred in connection with the consummation
      of
      the transactions contemplated by this Agreement (including, without limitation,
      all salaries and expenses of its officers and employees performing legal or
      accounting duties), the expense of any annual audit and the fees and expenses
      incurred in connection with the listing of the Registrable Securities on any
      securities exchange as required hereunder. In no event shall the Company be
      responsible for any broker or similar commissions of any Holder or, except
      to
      the extent provided for in the Transaction Documents, any legal fees or other
      costs of the Holders.

    (a) Indemnification
      by the Company.
      The
      Company shall, notwithstanding any termination of this Agreement, indemnify
      and
      hold harmless each Holder, the officers, directors, members, partners, agents,
      brokers (including brokers who offer and sell Registrable Securities as
      principal as a result of a pledge or any failure to perform under a margin
      call
      of Common Stock), investment advisors and employees (and any other Persons
      with
      a functionally equivalent role of a Person holding such titles, notwithstanding
      a lack of such title or any other title) of each of them, each Person who
      controls any such Holder (within the meaning of Section 15 of the Securities
      Act
      or Section 20 of the Exchange Act) and the officers, directors, members,
      shareholders, partners, agents and employees (and any other Persons with a
      functionally equivalent role of a Person holding such titles, notwithstanding
      a
      lack of such title or any other title) of each such controlling Person, to
      the
      fullest extent permitted by applicable law, from and against any and all losses,
      claims, damages, liabilities, costs (including, without limitation, reasonable
      attorneys’ fees) and expenses (collectively, “Losses”),
      as
      incurred, arising out of or relating to (1) any untrue or alleged untrue
      statement of a material fact contained in a Registration Statement, any
      Prospectus or any form of prospectus or in any amendment or supplement thereto
      or in any preliminary prospectus, or arising out of or relating to any omission
      or alleged omission of a material fact required to be stated therein or
      necessary to make the statements therein (in the case of any Prospectus or
      form
      of prospectus or supplement thereto, in light of the circumstances under which
      they were made) not misleading, or (2) any violation or alleged violation by
      the
      Company of the Securities Act, Exchange Act or any state securities law, or
      any
      rule or regulation thereunder, in connection with the performance of its
      obligations under this Agreement, except to the extent, but only to the extent,
      that (i) such untrue statements or omissions are based solely upon information
      regarding such Holder furnished in writing to the Company by such Holder
      expressly for use therein, or to the extent that such information relates to
      such Holder or such Holder’s proposed method of distribution of Registrable
      Securities and was reviewed and expressly approved in writing by such Holder
      expressly for use in a Registration Statement, such Prospectus or such form
      of
      Prospectus or in any amendment or supplement thereto (it being understood that
      the Holder has approved Annex A hereto for this purpose) or (ii) in the case
      of
      an occurrence of an event of the type specified in Section 3(d)(iii)-(vi),
      the
      use by such Holder of an outdated or defective Prospectus after the Company
      has
      notified such Holder in writing that the Prospectus is outdated or defective
      and
      prior to the receipt by such Holder of the Advice contemplated in Section 6(d).
      The Company shall notify the Holders promptly of the institution, threat or
      assertion of any Proceeding arising from or in connection with the transactions
      contemplated by this Agreement of which the Company is aware.

    (b) Indemnification
      by Holders.
      Each
      Holder shall, severally and not jointly, indemnify and hold harmless the
      Company, its directors, officers, agents and employees, each Person who controls
      the Company (within the meaning of Section 15 of the Securities Act and Section
      20 of the Exchange Act), and the directors, officers, agents or employees of
      such controlling Persons, to the fullest extent permitted by applicable law,
      from and against all Losses, as incurred, to the extent arising out of or based
      solely upon: (x) such Holder’s failure to comply with the prospectus delivery
      requirements of the Securities Act or (y) any untrue or alleged untrue statement
      of a material fact contained in any Registration Statement, any Prospectus,
      or
      any form of prospectus, or in any amendment or supplement thereto or in any
      preliminary prospectus, or arising out of or relating to any omission or alleged
      omission of a material fact required to be stated therein or necessary to make
      the statements therein not misleading (i) to the extent, but only to the extent,
      that such untrue statement or omission is contained in any information so
      furnished in writing by such Holder to the Company specifically for inclusion
      in
      such Registration Statement or such Prospectus or (ii) to the extent that such
      information relates to such Holder’s proposed method of distribution of
      Registrable Securities and was reviewed and expressly approved in writing by
      such Holder expressly for use in a Registration Statement (it being understood
      that the Holder has approved Annex A hereto for this purpose), such Prospectus
      or such form of Prospectus or in any amendment or supplement thereto or (ii)
      in
      the case of an occurrence of an event of the type specified in Section
      3(d)(iii)-(vi), the use by such Holder of an outdated or defective Prospectus
      after the Company has notified such Holder in writing that the Prospectus is
      outdated or defective and prior to the receipt by such Holder of the Advice
      contemplated in Section 6(d). In no event shall the liability of any selling
      Holder hereunder be greater in amount than the dollar amount of the net proceeds
      received by such Holder upon the sale of the Registrable Securities giving
      rise
      to such indemnification obligation.

    


    (c) Conduct
      of Indemnification Proceedings.
      If any
      Proceeding shall be brought or asserted against any Person entitled to indemnity
      hereunder (an “Indemnified
      Party”),
      such
      Indemnified Party shall promptly notify the Person from whom indemnity is sought
      (the “Indemnifying
      Party”)
      in
      writing, and the Indemnifying Party shall have the right to assume the defense
      thereof, including the employment of counsel reasonably satisfactory to the
      Indemnified Party and the payment of all fees and expenses incurred in
      connection with defense thereof; provided, that the failure of any Indemnified
      Party to give such notice shall not relieve the Indemnifying Party of its
      obligations or liabilities pursuant to this Agreement, except (and only) to
      the
      extent that it shall be finally determined by a court of competent jurisdiction
      (which determination is not subject to appeal or further review) that such
      failure shall have prejudiced the Indemnifying Party.

    



    
      
         

      

      
        12

        
          

        

      

      
         

      

    


    An
      Indemnified Party shall have the right to employ separate counsel in any such
      Proceeding and to participate in the defense thereof, but the fees and expenses
      of such counsel shall be at the expense of such Indemnified Party or Parties
      unless: (1) the Indemnifying Party has agreed in writing to pay such fees and
      expenses; (2) the Indemnifying Party shall have failed promptly to assume the
      defense of such Proceeding and to employ counsel reasonably satisfactory to
      such
      Indemnified Party in any such Proceeding; or (3) the named parties to any such
      Proceeding (including any impleaded parties) include both such Indemnified
      Party
      and the Indemnifying Party, and counsel to the Indemnified Party shall
      reasonably believe that a material conflict of interest is likely to exist
      if
      the same counsel were to represent such Indemnified Party and the Indemnifying
      Party (in which case, if such Indemnified Party notifies the Indemnifying Party
      in writing that it elects to employ separate counsel at the expense of the
      Indemnifying Party, the Indemnifying Party shall not have the right to assume
      the defense thereof and the reasonable fees and expenses of no more than one
      separate counsel shall be at the expense of the Indemnifying Party). The
      Indemnifying Party shall not be liable for any settlement of any such Proceeding
      effected without its written consent, which consent shall not be unreasonably
      withheld or delayed. No Indemnifying Party shall, without the prior written
      consent of the Indemnified Party, effect any settlement of any pending
      Proceeding in respect of which any Indemnified Party is a party, unless such
      settlement includes an unconditional release of such Indemnified Party from
      all
      liability on claims that are the subject matter of such Proceeding.

    


    Subject
      to the terms of this Agreement, all reasonable fees and expenses of the
      Indemnified Party (including reasonable fees and expenses to the extent incurred
      in connection with investigating or preparing to defend such Proceeding in
      a
      manner not inconsistent with this Section) shall be paid to the Indemnified
      Party, as incurred, within ten Trading Days of written notice thereof to the
      Indemnifying Party; provided, that the Indemnified Party shall promptly
      reimburse the Indemnifying Party for that portion of such fees and expenses
      applicable to such actions for which such Indemnified Party is judicially
      determined to be not entitled to indemnification hereunder.

    (d) Contribution.
      If the
      indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified
      Party or insufficient to hold an Indemnified Party harmless for any Losses,
      then
      each Indemnifying Party shall contribute to the amount paid or payable by such
      Indemnified Party, in such proportion as is appropriate to reflect the relative
      fault of the Indemnifying Party and Indemnified Party in connection with the
      actions, statements or omissions that resulted in such Losses as well as any
      other relevant equitable considerations. The relative fault of such Indemnifying
      Party and Indemnified Party shall be determined by reference to, among other
      things, whether any action in question, including any untrue or alleged untrue
      statement of a material fact or omission or alleged omission of a material
      fact,
      has been taken or made by, or relates to information supplied by, such
      Indemnifying Party or Indemnified Party, and the parties’ relative intent,
      knowledge, access to information and opportunity to correct or prevent such
      action, statement or omission. The amount paid or payable by a party as a result
      of any Losses shall be deemed to include, subject to the limitations set forth
      in this Agreement, any reasonable attorneys’ or other fees or expenses incurred
      by such party in connection with any Proceeding to the extent such party would
      have been indemnified for such fees or expenses if the indemnification provided
      for in this Section was available to such party in accordance with its
      terms.

    


    The
      parties hereto agree that it would not be just and equitable if contribution
      pursuant to this Section 5(d) were determined by pro rata allocation or by
      any
      other method of allocation that does not take into account the equitable
      considerations referred to in the immediately preceding paragraph.
      Notwithstanding the provisions of this Section 5(d), no Holder shall be required
      to contribute, in the aggregate, any amount in excess of the amount by which
      the
      proceeds actually received by such Holder from the sale of the Registrable
      Securities subject to the Proceeding exceeds the amount of any damages that
      such
      Holder has otherwise been required to pay by reason of such untrue or alleged
      untrue statement or omission or alleged omission, except in the case of fraud
      by
      such Holder.

    


    The
      indemnity and contribution agreements contained in this Section are in addition
      to any liability that the Indemnifying Parties may have to the Indemnified
      Parties.

    


    6.
       Miscellaneous

    


    (a) Remedies.
      In the
      event of a breach by the Company or by a Holder, of any of their respective
      obligations under this Agreement, each Holder or the Company, as the case may
      be, in addition to being entitled to exercise all rights granted by law and
      under this Agreement, including recovery of damages, will be entitled to
      specific performance of its rights under this Agreement. The Company and each
      Holder agree that monetary damages would not provide adequate compensation
      for
      any losses incurred by reason of a breach by it of any of the provisions of
      this
      Agreement and hereby further agrees that, in the event of any action for
      specific performance in respect of such breach, it shall not assert or shall
      waive the defense that a remedy at law would be adequate.

    (b) No
      Piggyback on Registrations.
      Neither
      the Company nor any of its security holders (other than the Holders in such
      capacity pursuant hereto) may include securities of the Company in the initial
      Registration Statement other than the Registrable Securities. The Company shall
      not file any registration statement which include Piggyback Shares or any other
      registration statements until (i) the initial Registration Statement required
      hereunder is declared effective by the Commission and (ii) the additional
      Registration Statements required under Section 3(c) are declared effective
      by
      the Commission, provided that this Section 6(b) shall not prohibit the Company
      from filing amendments to registration statements already filed.

    


    (c) Compliance.
      Each
      Holder covenants and agrees that it will comply with the prospectus delivery
      requirements of the Securities Act as applicable to it in connection with sales
      of Registrable Securities pursuant to a Registration Statement.

    


    (d) Discontinued
      Disposition.
      Each
      Holder agrees by its acquisition of Registrable Securities that, upon receipt
      of
      a notice from the Company of the occurrence of any event of the kind described
      in Section 3(d)(iii) through (vi), such Holder will forthwith discontinue
      disposition of such Registrable Securities under a Registration Statement until
      it is advised in writing (the “Advice”)
      by the
      Company that the use of the applicable Prospectus (as it may have been
      supplemented or amended) may be resumed. The Company will use its best efforts
      to ensure that the use of the Prospectus may be resumed as promptly as it
      practicable. The Company agrees and acknowledges that any periods during which
      the Holder is required to discontinue the disposition of the Registrable
      Securities hereunder shall be subject to the provisions of Section
      2(b).

    


    (e) Piggy-Back
      Registrations.
      If at
      any time during the Effectiveness Period there is not an effective Registration
      Statement covering all of the Registrable Securities and the Company shall
      determine to prepare and file with the Commission a registration statement
      relating to an offering for its own account or the account of others under
      the
      Securities Act of any of its equity securities, other than on Form S-4 or Form
      S-8 (each as promulgated under the Securities Act) or their then equivalents
      relating to equity securities to be issued solely in connection with any
      acquisition of any entity or business or equity securities issuable in
      connection with the stock option or other employee benefit plans, then the
      Company shall send to each Holder a written notice of such determination and,
      if
      within fifteen days after the date of such notice, any such Holder shall so
      request in writing, the Company shall include in such registration statement
      all
      or any part of such Registrable Securities such Holder requests to be
      registered; provided,
      however,
      that,
      the Company shall not be required to register any Registrable Securities
      pursuant to this Section 6(e) that are eligible for resale pursuant to Rule
      144(k) promulgated under the Securities Act or that are the subject of a then
      effective Registration Statement.

    (f) Amendments
      and Waivers.
      The
      provisions of this Agreement, including the provisions of this sentence, may
      not
      be amended, modified or supplemented, and waivers or consents to departures
      from
      the provisions hereof may not be given, unless the same shall be in writing
      and
      (a) if any Registrable Securities are held by one or more Qualified Investors,
      signed by each Qualified Investor holding Registrable Securities and the Company
      or (b) if no Registrable Securities are held by any Qualified Investor, signed
      by each Purchaser holding Registrable Securities and the Company.
      Notwithstanding the foregoing, a waiver or consent to depart from the provisions
      hereof with respect to a matter that relates exclusively to the rights of
      Holders and that does not directly or indirectly affect the rights of other
      Holders may be given by Holders of all of the Registrable Securities to which
      such waiver or consent relates; provided,
      however,
      that
      the provisions of this sentence may not be amended, modified, or supplemented
      except in accordance with the provisions of the immediately preceding sentence.
      

    


    (g) Notices.
      Any and
      all notices or other communications or deliveries required or permitted to
      be
      provided hereunder shall be delivered as set forth in the Purchase Agreement.
      

    


    (h) Successors
      and Assigns.
      This
      Agreement shall inure to the benefit of and be binding upon the successors
      and
      permitted assigns of each of the parties and shall inure to the benefit of
      each
      Holder. The Company may not assign (except by merger) its rights or obligations
      hereunder without the prior written consent of all of the Holders of the
      then-outstanding Registrable Securities. Each Holder may assign their respective
      rights hereunder in the manner and to the Persons as permitted under the
      Purchase Agreement.

    


    (i) No
      Inconsistent Agreements.
      Neither
      the Company nor any of its Subsidiaries has entered, as of the date hereof,
      nor
      shall the Company or any of its Subsidiaries, on or after the date of this
      Agreement, enter into any agreement with respect to its securities, that would
      have the effect of impairing the rights granted to the Holders in this Agreement
      or otherwise conflicts with the provisions hereof. Except as set forth on
Schedule
      6(i),
      neither
      the Company nor any of its subsidiaries has previously entered into any
      agreement granting any registration rights with respect to any of its securities
      to any Person that have not been satisfied in full.

    


    (j) Execution
      and Counterparts.
      This
      Agreement may be executed in two or more counterparts, all of which when taken
      together shall be considered one and the same agreement and shall become
      effective when counterparts have been signed by each party and delivered to
      the
      other party, it being understood that both parties need not sign the same
      counterpart. In the event that any signature is delivered by facsimile
      transmission or by e-mail delivery of a “.pdf” format data file, such signature
      shall create a valid and binding obligation of the party executing (or on whose
      behalf such signature is executed) with the same force and effect as if such
      facsimile or “.pdf” signature page were an original thereof.

    (k) Governing
      Law.
      All
      questions concerning the construction, validity, enforcement and interpretation
      of this Agreement shall be determined in accordance with the provisions of
      the
      Purchase Agreement.

    


    (l) Cumulative
      Remedies.
      The
      remedies provided herein are cumulative and not exclusive of any other remedies
      provided by law.

    


    (m) Severability.
      If any
      term, provision, covenant or restriction of this Agreement is held by a court
      of
      competent jurisdiction to be invalid, illegal, void or unenforceable, the
      remainder of the terms, provisions, covenants and restrictions set forth herein
      shall remain in full force and effect and shall in no way be affected, impaired
      or invalidated, and the parties hereto shall use their commercially reasonable
      efforts to find and employ an alternative means to achieve the same or
      substantially the same result as that contemplated by such term, provision,
      covenant or restriction. It is hereby stipulated and declared to be the
      intention of the parties that they would have executed the remaining terms,
      provisions, covenants and restrictions without including any of such that may
      be
      hereafter declared invalid, illegal, void or unenforceable.

    


    (n) Headings.
      The
      headings in this Agreement are for convenience only, do not constitute a part
      of
      this Agreement and shall not be deemed to limit or affect any of the provisions
      hereof.

    


    (o) Independent
      Nature of Holders’ Obligations and Rights.
      The
      obligations of each Holder hereunder are several and not joint with the
      obligations of any other Holder hereunder, and no Holder shall be responsible
      in
      any way for the performance of the obligations of any other Holder hereunder.
      Nothing contained herein or in any other agreement or document delivered at
      any
      closing, and no action taken by any Holder pursuant hereto or thereto, shall
      be
      deemed to constitute the Holders as a partnership, an association, a joint
      venture or any other kind of entity, or create a presumption that the Holders
      are in any way acting in concert with respect to such obligations or the
      transactions contemplated by this Agreement. Each Holder shall be entitled
      to
      protect and enforce its rights, including without limitation the rights arising
      out of this Agreement, and it shall not be necessary for any other Holder to
      be
      joined as an additional party in any proceeding for such purpose.

    ANNEX
      A

    


    Plan
      of Distribution

    


    Each
      Selling Stockholder (the “Selling
      Stockholders”)
      of the
      common stock and any of their pledgees, assignees and successors-in-interest
      may, from time to time, sell any or all of their shares of common stock on
      the
      OTC Bulletin Board or any other stock exchange, market or trading facility
      on
      which the shares are traded or in private transactions. These sales may be
      at
      fixed or negotiated prices. A Selling Stockholder may use any one or more of
      the
      following methods when selling shares:

    


    
      	 	
              ·

            	
              ordinary
                brokerage transactions and transactions in which the broker-dealer
                solicits purchasers;

            


    

    


    
      	 	
              ·

            	
              block
                trades in which the broker-dealer will attempt to sell the shares
                as agent
                but may position and resell a portion of the block as principal to
                facilitate the transaction;

            


    

    


    
      	 	
              ·

            	
              purchases
                by a broker-dealer as principal and resale by the broker-dealer for
                its
                account;

            


    

    


    
      	 	
              ·

            	
              an
                exchange distribution in accordance with the rules of the applicable
                exchange;

            


    

    


    
      	 	
              ·

            	
              privately
                negotiated transactions;

            


    

    


    
      	 	
              ·

            	
              settlement
                of short sales entered into after the effective date of the registration
                statement of which this prospectus is a
                part;

            


    

    


    
      	 	
              ·

            	
              broker-dealers
                may agree with the Selling Stockholders to sell a specified number
                of such
                shares at a stipulated price per
                share;

            


    

    


    
      	 	
              ·

            	
              through
                the writing or settlement of options or other hedging transactions,
                whether through an options exchange or otherwise;
                

            


    

    


    
      	 	
              ·

            	
              a
                combination of any such methods of sale;
                or

            


    

    


    
      	 	
              ·

            	
              any
                other method permitted pursuant to applicable
                law.

            


    

    


    The
      Selling Stockholders may also sell shares under Rule 144 under the Securities
      Act of 1933, as amended (the “Securities
      Act”),
      if
      available, rather than under this prospectus.

    



    
      
         

      

      
        20

        
          

        

      

      
         

      

    


    Broker-dealers
      engaged by the Selling Stockholders may arrange for other brokers-dealers to
      participate in sales. Broker-dealers may receive commissions or discounts from
      the Selling Stockholders (or, if any broker-dealer acts as agent for the
      purchaser of shares, from the purchaser) in amounts to be negotiated, but,
      except as set forth in a supplement to this Prospectus, in the case of an agency
      transaction not in excess of a customary brokerage commission in compliance
      with
      NASDR Rule 2440; and in the case of a principal transaction a markup or markdown
      in compliance with NASDR IM-2440. 

    


    In
      connection with the sale of the common stock or interests therein, the Selling
      Stockholders may enter into hedging transactions with broker-dealers or other
      financial institutions, which may in turn engage in short sales of the Common
      Stock in the course of hedging the positions they assume. The Selling
      Stockholders may also sell shares of the common stock short and deliver these
      securities to close out their short positions, or loan or pledge the common
      stock to broker-dealers that in turn may sell these securities. The Selling
      Stockholders may also enter into option or other transactions with
      broker-dealers or other financial institutions or the creation of one or more
      derivative securities which require the delivery to such broker-dealer or other
      financial institution of shares offered by this prospectus, which shares such
      broker-dealer or other financial institution may resell pursuant to this
      prospectus (as supplemented or amended to reflect such
      transaction).

    


    The
      Selling Stockholders and any broker-dealers or agents that are involved in
      selling the shares may be deemed to be “underwriters” within the meaning of the
      Securities Act in connection with such sales. In such event, any commissions
      received by such broker-dealers or agents and any profit on the resale of the
      shares purchased by them may be deemed to be underwriting commissions or
      discounts under the Securities Act. Each Selling Stockholder has informed the
      Company that it does not have any written or oral agreement or understanding,
      directly or indirectly, with any person to distribute the Common Stock. In
      no
      event shall any broker-dealer receive fees, commissions and markups which,
      in
      the aggregate, would exceed eight percent (8%).

    


    The
      Company is required to pay certain fees and expenses incurred by the Company
      incident to the registration of the shares. The Company has agreed to indemnify
      the Selling Stockholders against certain losses, claims, damages and
      liabilities, including liabilities under the Securities Act. 

    


    Because
      Selling Stockholders may be deemed to be “underwriters” within the meaning of
      the Securities Act, they will be subject to the prospectus delivery requirements
      of the Securities Act including Rule 172 thereunder. In addition, any securities
      covered by this prospectus which qualify for sale pursuant to Rule 144 under
      the
      Securities Act may be sold under Rule 144 rather than under this prospectus.
      There is no underwriter or coordinating broker acting in connection with the
      proposed sale of the resale shares by the Selling Stockholders.

    



    
      
         

      

      
        21

        
          

        

      

      
         

      

    


    We
      agreed
      to keep this prospectus effective until the earlier of (i) the date on which
      the
      shares may be resold by the Selling Stockholders without registration and
      without regard to any volume limitations by reason of Rule 144(k) under the
      Securities Act or any other rule of similar effect or (ii) all of the shares
      have been sold pursuant to this prospectus or Rule 144 under the Securities
      Act
      or any other rule of similar effect. The resale shares will be sold only through
      registered or licensed brokers or dealers if required under applicable state
      securities laws. In addition, in certain states, the resale shares may not
      be
      sold unless they have been registered or qualified for sale in the applicable
      state or an exemption from the registration or qualification requirement is
      available and is complied with.

    


    Under
      applicable rules and regulations under the Exchange Act, any person engaged
      in
      the distribution of the resale shares may not simultaneously engage in market
      making activities with respect to the common stock for the applicable restricted
      period, as defined in Regulation M, prior to the commencement of the
      distribution. In addition, the Selling Stockholders will be subject to
      applicable provisions of the Exchange Act and the rules and regulations
      thereunder, including Regulation M, which may limit the timing of purchases
      and
      sales of shares of the common stock by the Selling Stockholders or any other
      person. We will make copies of this prospectus available to the Selling
      Stockholders and have informed them of the need to deliver a copy of this
      prospectus to each purchaser at or prior to the time of the sale (including
      by
      compliance with Rule 172 under the Securities Act).
