2.  REGISTRATION RIGHTS.





2.1  Demand Registration .





2.1.1.Request for Registration. 
      At any time and from time to time on or after the Release Date, the holders
      of a
      majority-in-interest of the Registrable Securities held by the Investors or
      the
      transferees of the Investors, may make a written demand for registration under
      the Securities Act of all or part of their Registrable Securities (a
“Demand
      Registration”). 
      Any demand for a Demand Registration shall specify the number of shares of
      Registrable Securities proposed to be sold and the intended method(s) of
      distribution thereof.  The Company will notify all holders of Registrable
      Securities of the demand, and each holder of Registrable Securities who wishes
      to include all or a portion of such holder’s Registrable Securities in the
      Demand Registration (each such holder including shares of Registrable Securities
      in such registration, a “Demanding
      Holder”)
      shall
      so notify the Company within fifteen (15) days after the receipt by the holder
      of the notice from the Company.  Upon any such request, the Demanding
      Holders shall be entitled to have their Registrable Securities included in
      the
      Demand Registration, subject to Section 2.1.4 and the provisos set forth in
      Section 3.1.1.  The Company shall not be obligated to effect more than
      an aggregate of two (2) Demand Registrations under this Section 2.1.1 in
      respect of Registrable Securities.





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      until, (i) such stop order or injunction is removed, rescinded or otherwise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









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





2.1.4.  Reduction of Offering . 
      If the managing Underwriter or Underwriters for a Demand Registration that
      is to
      be an underwritten offering advises the Company and the Demanding Holders in
      writing that the dollar amount or number of shares of Registrable Securities
      which the Demanding Holders desire to sell, taken together with all other 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
      shareholders of the Company who desire to sell, exceeds the maximum dollar
      amount or maximum number of shares that can be sold in such offering without
      adversely affecting the proposed offering price, the timing, the distribution
      method, or the probability of success of such offering (such maximum dollar
      amount or maximum number of shares, as applicable, the “ Maximum
      Number of Shares ”),
      then
      the Company shall include in such registration:  (i) first, the Registrable
      Securities as to which Demand Registration has been requested by the Demanding
      Holders ( pro
      rata in
      accordance with the number of shares of Registrable Securities which such
      Demanding Holder has requested be included in such registration, regardless
      of
      the number of shares of Registrable Securities held by each Demanding Holder)
      that can be sold without exceeding the Maximum Number of Shares; (ii) second,
      to
      the extent that the Maximum Number of Shares has not been reached under the
      foregoing clause (i), the shares of Common Stock or other securities that the
      Company desires to sell that can be sold without exceeding the Maximum Number
      of
      Shares; (iii) third, to the extent that the Maximum Number of Shares has not
      been reached under the foregoing clauses (i) and (ii), the shares of Common
      Stock for the account of other persons that the Company is obligated to register
      pursuant to written contractual arrangements with such persons and that can
      be
      sold without exceeding the Maximum Number of Shares; and (v) fourth, to the
      extent that the Maximum Number of Shares have not been reached under the
      foregoing clauses (i), (ii), and (iii), the shares of Common Stock that other
      shareholders desire to sell that can be sold without exceeding the Maximum
      Number of Shares.





2.1.5.  Withdrawal .
      If a
      majority-in-interest of the Demanding Holders disapprove of the terms of any
      underwriting or are not entitled to include all of their Registrable Securities
      in any offering, such majority-in-interest of the Demanding Holders may elect
      to
      withdraw from such offering by giving written notice to the Company and the
      Underwriter or Underwriters of their request to withdraw prior to the
      effectiveness of the Registration Statement filed with the Commission with
      respect to such Demand Registration.  If the majority-in-interest of the
      Demanding Holders withdraws from a proposed offering relating to a Demand
      Registration, then such registration shall not count as a Demand Registration
      provided for in Section 2.1.1.




2.2  Piggy-Back Registration .





2.2.1.  Piggy-Back Rights . 
      If at any time on or after the Release Date the Company proposes to file a
      Registration Statement under the Securities Act with respect to an offering
      of
      equity securities, or securities or other obligations exercisable or
      exchangeable for, or convertible into, equity securities, by the Company for
      its
      own account or for shareholders of the Company for their account (or by the
      Company and by shareholders of the Company including, without limitation,
      pursuant to Section 2.1), other than a Registration Statement (i) filed in
      connection with any employee stock option or other benefit plan, (ii) for an
      exchange offer or offering of securities solely to the Company’s existing
      shareholders, (iii) for an offering of debt that is convertible into equity
      securities of the Company or (iv) for a dividend reinvestment plan, then
      the Company shall (x) give written notice of such proposed filing to the holders
      of Registrable Securities as soon as practicable but in no event less than
      ten
      (10) days before the anticipated filing date, which notice shall describe the
      amount and type of securities to be included in such offering, the intended
      method(s) of distribution, and the name of the proposed managing Underwriter
      or
      Underwriters, if any, of the offering, and (y) offer to the holders of
      Registrable Securities in such notice the opportunity to register the sale
      of
      such number of shares of Registrable Securities as such holders may request
      in
      writing within fifteen (15) days following receipt of such notice (a
“ Piggy-Back
      Registration ”). 
      The Company shall cause such Registrable Securities to be included in such
      registration and shall use its best efforts to cause the managing Underwriter

      Underwriters of a proposed underwritten offering to permit the Registrable
      Securities requested to be included in a Piggy-Back Registration to be included
      on the same terms and conditions as any similar securities of the Company and
      to
      permit the sale or other disposition of such Registrable Securities in
      accordance with the intended method(s) of distribution thereof.  All
      holders of Registrable Securities proposing to distribute their securities
      through a Piggy-Back Registration that involves an Underwriter or Underwriters
      shall enter into an underwriting agreement in customary form with the
      Underwriter or Underwriters selected for such Piggy-Back
      Registration.









2.2.2.  Reduction of Offering . 
      If the managing Underwriter or Underwriters for a Piggy-Back Registration that
      is to be an underwritten offering advises the Company and the holders of
      Registrable Securities in writing that the dollar amount or number of 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 shareholders
      of
      the Company, exceeds the Maximum Number of Shares, then the Company shall
      include in any such registration:

      has
      actually requested to be included in such registration, regardless of the number
      of shares of Common Stock with respect to which such persons have the right
      to
      request such inclusion) that can be sold without exceeding the Maximum Number
      of
      Shares; and

3.  REGISTRATION PROCEDURES.





3.1  Filings; Information .

      demand registration to which such Piggy-Back Registration relates, in each
      case
      if the Company shall furnish to the holders a certificate signed by the Chief
      Executive Officer of the Company stating that, in the good faith judgment of
      the
      Board of Directors of the Company, it would be materially detrimental to the
      Company and its shareholders for such Registration Statement to be effected
      at
      such time;provided further,however,

      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

      Governmental Authorities as may be necessary by virtue of the business and
      operations of the Company and do any and all other acts and things that may
      be
      necessary or advisable to enable the holders of Registrable Securities included
      in such Registration Statement to consummate the disposition of such Registrable
      Securities in such jurisdictions; provided , however ,
      that
      the Company shall not be required to qualify generally to do business in any

      Registrable Securities.  The representations, warranties and covenants of
      the Company in any underwriting agreement which are made to or for the benefit

      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

      any offering of Registrable Securities hereunder, which cooperation shall
      include, without limitation, the preparation of the Registration Statement
      with
      respect to such offering and all other offering materials and related documents,
      and participation in meetings with Underwriters, attorneys, accountants and
      potential investors.

      the

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











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




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





3.2  Obligation to Suspend Distribution . 
      Upon receipt of any notice from the Company of the happening of any event of
      the
      kind described in Section 3.1.4(iv), or, in the case of a resale
      registration on Form 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 Company’s Board of Directors, of the ability of all
“insiders” covered by such program to transact in the Company’s securities
      because of the existence of material non-public information and holder would
      be
      deemed an “insider” under such program, each holder of Registrable Securities
      included in any registration shall immediately discontinue disposition of such
      Registrable Securities pursuant to the Registration Statement covering such
      Registrable Securities until such holder receives the supplemented or amended
      prospectus contemplated by Section 3.1.4(iv) or the restriction on the
      ability of “insiders” to transact in the Company’s securities is removed or is
      inapplicable to such holder, 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.

      (including, without limitation, all salaries and expenses of its officers and

      letters requested pursuant to Section 3.1.9); (viii) the fees and
      expenses of any special experts retained by the Company in connection with
      such
      registration and (ix)  the fees and expenses of one legal counsel
      selected by the holders of a majority-in-interest of the Registrable Securities
      included in such registration.  The Company shall have no obligation to pay
      any underwriting discounts or selling commissions or transfer taxes, if any,
      attributable to the Registrable Securities being sold by the holders thereof,
      which underwriting discounts or selling commissions or transfer taxes, if any,
      shall be borne by such holders.  Additionally, in an underwritten offering,
      all selling shareholders and the Company shall bear the expenses of the
      underwriter pro rata in proportion to the respective amount of shares each
      is
      selling in such offering.





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










4.  INDEMNIFICATION AND CONTRIBUTION.





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





4.2  Indemnification by Holders of Registrable Securities . 
      Each selling holder of Registrable Securities will, in the event that any
      registration is being effected under the Securities Act pursuant to this
      Agreement of any Registrable Securities held by such selling holder, indemnify
      and hold harmless the Company, each of its directors and officers and each
      underwriter (if any), and each other person, if any, who controls such 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 such controlling person for any legal or other expenses reasonably
      incurred by any of them in connection with investigation or defending any such
      loss, claim, damage, liability or action.  Each selling holder’s
      indemnification obligations hereunder shall be several and not joint and shall
      be limited to the amount of any net proceeds (after payment of all underwriting
      fees, discounts, commissions and taxes) actually received by such selling holder
      from the sale of Registrable Securities which gave rise to such indemnification
      obligation.





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 reasonably satisfactory to the Indemnified Party.  After notice
      from the Indemnifying Party to the Indemnified Party of its election to assume
      control of the defense of such claim or action, the Indemnifying Party shall
      not
      be liable to the Indemnified Party for any legal or other expenses subsequently
      incurred by the Indemnified Party in connection with the defense thereof other
      than reasonable costs of investigation;provided,however,
      that in
      any action in which both the Indemnified Party and the Indemnifying Party are
      named as defendants, the Indemnified Party shall have the right to employ
      separate counsel (but no more than one such separate counsel) to represent
      the
      Indemnified Party and its controlling persons who may be subject to liability
      arising out of any claim in respect of which indemnity may be sought by the
      Indemnified Party against the Indemnifying Party, with the fees and expenses
      of
      such counsel to be paid by such Indemnifying Party if, based upon the written
      opinion of counsel of such Indemnified Party, representation of both parties
      by
      the same counsel would be inappropriate due to actual or potential differing
      interests between them.  No Indemnifying Party shall, without the prior
      written consent of the Indemnified Party, consent to entry of judgment or effect
      any settlement of any claim or pending or threatened proceeding in respect
      of
      which the Indemnified Party is or could have been a party and indemnity could
      have been sought hereunder by such Indemnified Party, unless such judgment
      or
      settlement includes an unconditional release of such Indemnified Party from
      all
      liability arising out of such claim or proceeding.








4.4  Contribution .





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





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




5.  UNDERWRITING AND DISTRIBUTION.





5.1  Rule 144 . 
      The Company covenants that it shall file 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.
