      the counsel to the Company pursuant to a written opinion letter to such

      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 with the Commission a form of prospectus
      pursuant to Rule 424(b)(5).
            (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 30 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 unless any
      such amendment requires updated financial information in which case, the
      Company may file a pre-effective amendment and respond to comments at any
      time up to the sooner of the date that is 45 days after the end of the
      previous fiscal quarter or 90 days after the end of the previous fiscal
      year, 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
      not permitted to utilize the Prospectus therein to resell such Registrable
      Securities for 20 consecutive Trading Days but no more than an aggregate
      of 30 Trading Days during any 12-month period (which need not be
      consecutive Trading 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 30 calendar day period is exceeded, or for purposes of clause
      (v) the date on which such 20 or 30 Trading 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
                                       3
      (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 0.5%
      of the aggregate purchase price paid by such Holder pursuant to the
      Purchase Agreement for any Registrable Securities then held by such
      Holder. 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 10% 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.
      3. Registration Procedures
      In connection with the Company's registration obligations hereunder, the
Company shall:
            (a) Not less than five Trading Days prior to the filing of each
      Registration Statement or 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 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 such documents except that if the Company is unable to file a
      Registration Statement after having received any such objection, and
      provided that the Company is working diligently to respond to such
      objections, then no penalty shall be assessed against the Company under
      Section 2(b) if any such failure results in occurrence of an Event. Each
      Holder agrees to furnish to the Company a completed Questionnaire in the
      form attached to this Agreement as Annex B (a "Selling Shareholder
      Questionnaire") not less than two Trading Days prior to the Filing Date or
      by the end of the fourth Trading Day following the date on which such
      Holder receives draft materials in accordance with this Section.
            (b) (i) 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
                                       4
      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; 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.
            (c) Notify the Holders of Registrable Securities to be sold (which
      notice shall, pursuant to clauses (ii) 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 five Trading Days 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 (the Company shall provide true and complete copies
      thereof and all written responses thereto to each of the Holders); 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.
                                       5
            (d) 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.
            (e) 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 all exhibits to the extent requested by such Person
      (including those previously furnished or incorporated by reference)
      promptly after the filing of such documents with the Commission.
            (f) Promptly deliver to each Holder, without charge, as many copies
      of the Prospectus or Prospectuses (including each form of prospectus) and
      each amendment or supplement thereto as such Persons may reasonably
      request in connection with resales by the Holder of Registrable
      Securities. Subject 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 on any notice
      pursuant to Section 3(c).
            (g) If NASDR Rule 2710 requires any broker-dealer to make a filing
      prior to executing a sale by a Holder, make an Issuer Filing with the
      NASDR, Inc. Corporate Financing Department pursuant to NASDR Rule
      2710(b)(10)(A)(i) and respond within five Trading Days to any comments
      received from NASDR in connection therewith, and pay the filing fee
      required in connection therewith.
            (h) 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.
                                       6
            (i) 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.
            (j) 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 (ii) through (vi) of Section 3(c) 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(j) 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
      120 days (which need not be consecutive days) in any 12 month period.
            (k) Comply with all applicable rules and regulations of the
      Commission.
            (l) 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
      person thereof that has 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.
      4. 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, fees and expenses (A) with respect to filings
required to be made with the Trading Market on which the Common Stock is then
listed for trading, (B) in compliance with applicable state securities or Blue
Sky laws reasonably agreed to by the Company in writing (including, without
limitation, fees and disbursements of counsel for the Company in connection with
Blue Sky qualifications or exemptions of the Registrable Securities and
                                       7
determination of the eligibility of the Registrable Securities for investment
under the laws of such jurisdictions as requested by the Holders) 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
retained by the Company in connection with the consummation of the transactions
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 or, except to the extent
provided for in the Transaction Documents, any legal fees or other costs of the
Holders.
      5. Indemnification
            (a) Indemnification by the Company. The Company shall,
      notwithstanding any termination of this Agreement, indemnify and hold
      harmless each Holder, the officers, directors, 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 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, agents and employees 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 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,
      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
                                       8
      Section 3(c)(ii)-(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(c). 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 (1)
      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 (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 (2) in the case of an occurrence of an event of the
      type specified in Section 3(c)(ii)-(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(c).
      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.
                                       9
            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) after having received proper
      notice pursuant to Section 6(f) herein, 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 such 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 one
      separate counsel shall be at the expense of the Indemnifying Party)
      provided however, that the Indemnifying Party shall not be obligated to
      reimburse all Indemnified Parties and all Purchasers for more than one
      separate counsel. 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. 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 not entitled to indemnification hereunder,
      determined based upon the relative faults of the parties.
            (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
                                       10
      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 reasonable 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 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 waive the defense that a remedy at law
      would be adequate.
            (b) No Piggyback on Registrations. Except as set forth on Schedule
      6(b) attached hereto, 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. Except as set forth on Schedule 6(b), no
      Person has any right to cause the Company to effect the registration under
      the Securities Act of any securities of the Company. The Company shall not
      file any other registration statements until the initial Registration
      Statement required hereunder is declared effective by the Commission,
      unless otherwise required to do so under an agreement set forth in
      Schedule 6(b), provided that (i) this Section 6(b) shall not prohibit the
      Company from filing amendments to registration statements already filed
      and (ii) nothing shall prohibit the Company from filing a registration
      statement covering the sale of securities issued in connection with a
      financing for which the Holder receives an adjustment under Section 4.14
      of the Purchase Agreement.
                                       11
            (c) Compliance. Each Holder agrees that it will sell securities only
      in those jurisdictions indicated by the Company as being available for
      sale of the Registrable Securities. Each Holder covenants and agrees that
      it will comply with the prospectus delivery requirements of the Securities
      Act and all Blue Sky requirements 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 such Registrable Securities that, upon receipt of a notice from the
      Company of the occurrence of any event of the kind described in Section
      3(c), such Holder will forthwith discontinue disposition of such
      Registrable Securities under a Registration Statement until such Holder's
      receipt of the copies of the supplemented Prospectus and/or amended
      Registration Statement or until it is advised in writing (the "Advice") by
      the Company that the use of the applicable Prospectus may be resumed, and,
      in either case, has received copies of any additional or supplemental
      filings that are incorporated or deemed to be incorporated by reference in
      such Prospectus or Registration Statement. 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 pursuant to a Registration Statement
      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 signed by
      the Company and each Holder of the then outstanding Registrable
      Securities. Notwithstanding the foregoing, a waiver or consent to depart
                                       12
      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 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(b), 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
      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 Agreement. In the event that any signature is delivered by
      facsimile transmission, such signature shall create a valid binding
      obligation of the party executing (or on whose behalf such signature is
      executed) the same with the same force and effect as if such facsimile
      signature were the 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 remedies provided by law.
                                       13
            (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 of
      reference only and shall not limit or otherwise affect the meaning 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
("Common Stock") of Astralis Ltd., a Delaware corporation (the "Company") 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 Trading Market 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:
      o     ordinary brokerage transactions and transactions in which the
            broker-dealer solicits purchasers;
      o     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;
      o     purchases by a broker-dealer as principal and resale by the
            broker-dealer for its account;
      o     an exchange distribution in accordance with the rules of the
            applicable exchange;
      o     privately negotiated transactions;
      o     settlement of short sales entered into after the effective date of
            the registration statement of which this prospectus is a part;
      o     broker-dealers may agree with the Selling Stockholders to sell a
            specified number of such shares at a stipulated price per share;
      o     a combination of any such methods of sale;
      o     through the writing or settlement of options or other hedging
            transactions, whether through an options exchange or otherwise; or
      o     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.
      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.
                                       17
      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. 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. Each Selling
Stockholder has advised us that they have not entered into any written or oral
agreements, understandings or arrangements with any underwriter or broker-dealer
regarding the sale of the resale shares. There is no underwriter or coordinating
broker acting in connection with the proposed sale of the resale shares by the
Selling Stockholders.
      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(e) under the Securities Act or any other rule of similar effect or (ii) all
of the shares have been sold pursuant to the 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.
                                       18
      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 a period of two
business days 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.
