      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 and not less than two Trading Day prior to the
      filing of any related amendment or supplement thereto, the Company shall,
      furnish to each Holder the selling stockholder and plan of distribution
      sections made a part thereof, along with any other section that
      specifically references a Holder. Each Holder agrees to be named in the
      Registration Statement and to carry out the offer and sale of Registrable
      Securities held by such Holder in a conformance with the Plan of
      Distribution attached hereto as Annex A, as modified by the Company as
      necessary to conform to comments from the Commission. 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") by
      the end of the fourth Trading Day following the date on which such Holder
      receives the Selling Shareholder Questionnaire and draft materials in
      accordance with this Section. The Company shall ensure that each
      Registration Statement (including any amendments or supplements thereto
      and prospectuses contained therein) shall not contain any 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 the case of
      prospectuses, in the light of the circumstances in which they were made)
      not misleading.

            (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, except for periods
      based on events described in Section 3(c), (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
      promptly to any comments received from the Commission with respect to a
      Registration Statement or any amendment thereto; and (iv) comply in all
      material respects with the provisions of the Securities Act and the
      Exchange Act applicable to the Company with respect to the disposition of
      all Registrable Securities covered by a Registration Statement during the
      applicable period in accordance 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 (iv) 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 (i) with
      respect to a Registration Statement or any post-effective amendment, when
      the same has become effective; (ii) of the issuance by the Commission or
      any other federal or state governmental authority of any stop order
      suspending the

                                     - 3 -

<PAGE>

      effectiveness of a Registration Statement covering any or all of the
      Registrable Securities; (iii) 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 (iv) 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.
      Any and all of such information contemplated by subparagraphs (i) through
      (iv) shall remain confidential to each Holder until such information
      otherwise becomes public, unless disclosure by a Holder is required by
      law.

            (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 final Prospectus and each final amendment or supplement
      thereto, promptly after the filing of such documents with the Commission,
      for Holder's delivery in connection with a sale of the Registrable
      Securities.

            (f) Subject to the terms of this Agreement, the Company hereby
      consents to the use of each Prospectus and each amendment or supplement
      thereto, provided by the Company pursuant to subpart (e) above, 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).

            (g) 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.

                                     - 4 -

            (h) 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 Securities Act, 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.

            (i) 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 (iv) 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.

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

            (k) The Company may require each selling Holder to furnish to the
      Company a certified statement as to (i) the number of shares of Common
      Stock beneficially owned by such Holder, (ii) the natural persons thereof
      that have voting and dispositive control over the shares of Common Stock,
      and (iii) any affiliation between the Holder and either the Company's
      independent accountants or any member of the NASD.

            (l) The Company shall use its best efforts either to cause all of
      the Registrable Securities covered by a Registration Statement to be
      listed on the primary securities exchange or stock market on which
      securities of the same class or series issued by the Company are then
      listed, if any, if the listing of such Registrable Securities is then
      permitted under the rules of such exchange or stock market.

            (m) If requested by a Holder, the Company shall as soon as
      practicable (i) incorporate in a prospectus supplement or post-effective
      amendment such information as a Holder reasonably requests to be included
      therein relating to the sale and distribution of Registrable Securities,
      including, without limitation, information with respect to the number of
      Registrable Securities being offered or sold, the purchase price being
      paid therefor and any other terms of the offering of the Registrable
      Securities to be sold in such offering; (ii) make all required filings of
      such prospectus supplement or post-effective amendment after being
      notified of the matters to be incorporated in such prospectus supplement
      or post-effective amendment; and (iii) supplement or make amendments to
      any Registration Statement if reasonably requested by a Holder holding any
      Registrable Securities.

                                     - 5 -

      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 any Trading Market on which the Common Stock is then
listed for trading, and (B) in compliance with applicable state securities or
Blue Sky laws reasonably agreed to by the Company in writing), (ii) printing

printing certificates for Registrable Securities, (iii) messenger, telephone and
delivery expenses incurred by the Company, (iv) fees and disbursements of

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

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.

      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, members, partners,
      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, members, shareholders,
      partners, 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 (1) any 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 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, (2) any 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

                                     - 6 -

<PAGE>

      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), (ii) in the case of an
      occurrence of an event of the type specified in Section 3(c)(ii)-(iv), 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), or (iii) any such untrue statement,
      omission or violation is directly related to and primarily the result of a
      material breach of this Agreement or violation of law by Holder; or (3)
      any violation of this Agreement.

            (b) Indemnification by Holders. Each Holder shall, severally and not
      jointly, indemnify and hold harmless the Company, its directors, officers,
      agents, attorneys 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, attorneys 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, (y) a
      material breach of this Agreement or violation of law by Holder, or (z)
      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 (iii) in the case
      of an occurrence of an event of the type specified in Section
      3(c)(ii)-(iv), 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

                                     - 7 -

<PAGE>

      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 such failure shall have prejudiced the Indemnifying
      Party.

            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 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.

            Subject to the terms of this Agreement, all reasonable fees and
      expenses of the Indemnified Party owing under this Section 5 (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.

            (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
      statement of a material fact or 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. Reports Under the 1934 Act.

            With a view to making available to the Holders the benefits of Rule
144 promulgated under the Securities Act or any other similar rule or regulation
of the Commission that may at any time permit the Holders to sell securities of
the Company to the public without registration ("Rule 144"), the Company agrees
to:

            (a) make and keep public information available, as those terms are
understood and defined in Rule 144;

            (b) file with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Securities Exchange Act of 1934, as amended (the "1934 Act") so long as the
Company remains subject to such requirements and the filing of such reports and
other documents is required for the applicable provisions of Rule 144; and

            (c) furnish to each Holder so long as such Holder owns Registrable
Securities, promptly upon request, (i) a written statement by the Company, if
true, that it has complied with the reporting requirements of Rule 144, the
Securities Act and the 1934 Act, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested to
permit the Holders to sell such securities pursuant to Rule 144 without
registration.

      7. Miscellaneous

            (a) Piggyback on Registrations. The Company and its security holders
      (other than the Holders in such capacity pursuant hereto) designated by
      the Company may include securities of the Company in the Registration
      Statement in addition to the Registrable Securities.

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

                                     - 9 -

<PAGE>

            (c) 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(c), 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.

            (d) 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 the Holders of at least a majority the then outstanding
      Registrable Securities. 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.

            (e) 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, as the case may be.

            (f) 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 (except by merger) or obligations
      hereunder without the prior written consent of at least a majority of the
      Holders of the then-outstanding Registrable Securities. The rights under
      this Agreement shall be automatically assignable by any Holder to any
      transferee of 50% or more of such Holder's Registrable Securities if: (i)
      such Holder agrees in writing with the transferee or assignee to assign
      such rights and a copy of such agreement is furnished to the Company
      promptly after such assignment; (ii) the Company is, promptly after such
      transfer or assignment, furnished with written notice of (a) the name and
      address of such transferee or assignee and (b) the securities with respect
      to which such registration rights are being transferred or assigned; (iii)
      immediately following such transfer or assignment the further disposition
      of such securities by the transferee or assignee is restricted under the
      Securities Act and applicable state securities laws; (iv) at or before the
      time the Company receives the written notice contemplated by clause (ii)
      of this sentence the transferee or assignee agrees in writing with the
      Company to be bound by all of the provisions contained herein; and (v)
      such transfer shall have been made in accordance with the applicable
      requirements of the Purchase Agreement.

            (g) 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.

            (h) 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.

            (i) Governing Law. All questions concerning the construction,
      validity, enforcement and interpretation of this Agreement shall be
      governed by and construed and enforced in accordance with the internal
      laws of the State of Nevada, without regard to the principles of conflicts
      of law thereof. Each party agrees that all legal proceedings concerning
      the interpretations, enforcement and defense of the transactions
      contemplated by this Agreement (whether brought against a party hereto or
      its respective affiliates, directors, officers, shareholders, employees or
      agents) shall be commenced exclusively in the state and federal courts
      sitting in the State of Nevada. The parties hereby waive all rights to a
      trial by jury. If either party shall commence an action or proceeding to
      enforce any provisions of this Agreement, then the prevailing party in
      such action or proceeding shall be reimbursed by the other party for its
      reasonable attorneys' fees and other costs and expenses incurred with the
      investigation, preparation and prosecution of such action or proceeding.

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

            (k) 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.

            (l) 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.

            (m) 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

      The selling stockholders may, from time to time, sell any or all of their
shares of common stock on any stock exchange, market or trading facility on
which the shares are traded or in private transactions. These sales may be at
fixed prices, at prevailing market prices at the time of the sale, at varying
prices determined at the time of sale, or at negotiated prices. The selling
stockholders 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;

    -   short sales;

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

    -   a combination of any such methods of sale; and

    -   any other method permitted pursuant to applicable law.

      The selling stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

      The selling stockholders may also engage in puts and calls and other
transactions in our securities or derivatives of our securities and may sell or
deliver shares in connection with these trades.

      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. The selling stockholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved. Any
profits on the resale of shares of common stock by a broker-dealer acting as
principal might be deemed to be underwriting discounts or commissions under the
Securities Act. Discounts, concessions, commissions and similar selling
expenses, if any, attributable to the sale of shares will be borne by a selling
stockholder. The selling stockholders may agree to indemnify any agent, dealer
or broker-dealer that participates in transactions involving sales of the shares
if liabilities are imposed on that person under the Securities Act. In
connection with sales of the shares of common stock or otherwise, the selling
stockholders may enter into hedging transactions with broker-dealers, which may
in turn engage in short sales of the shares of common stock in the course of
hedging in positions they assume. The selling stockholders may also sell shares
of common stock short and deliver shares of common stock covered by this

                                     - 15 -

<PAGE>

prospectus to close out short positions and to return borrowed shares in
connection with such short sales. The selling stockholders may also loan or
pledge shares of common stock to broker-dealers that in turn may sell such
shares.

      The selling stockholders may from time to time pledge or grant a security
interest in some or all of the shares of common stock owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell the shares of common stock from time to time under
this prospectus after we have filed a supplement to this prospectus under Rule
424(b)(3) or other applicable provision of the Securities Act of 1933 amending
the list of selling stockholders to include the pledgee, transferee or other
successors in interest as selling stockholders under this prospectus.

      The selling stockholders also may transfer the shares of common stock in
other circumstances, in which case the transferees, pledgees or other successors
in interest will be the selling beneficial owners for purposes of this
prospectus and may sell the shares of common stock from time to time under this
prospectus after we have filed a supplement to this prospectus under Rule
424(b)(3) or other applicable provision of the Securities Act of 1933 amending
the list of selling stockholders to include the pledgee, transferee or other
successors in interest as selling stockholders under this prospectus.

      The selling stockholders and any broker-dealers or agents that are
involved in selling the shares of common stock 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 of common stock purchased by them may
be deemed to be underwriting commissions or discounts under the Securities Act.

      We are required to pay all fees and expenses incident to the registration
of the shares of common stock. We have agreed to indemnify the selling
stockholders against certain claims, damages and liabilities, including
liabilities under the Securities Act.

      The selling stockholders have advised us that they have not entered into
any agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their shares of common stock, nor is there
an underwriter or coordinating broker acting in connection with a proposed sale
of shares of common stock by any selling stockholder. If we are notified by any
selling stockholder that any material arrangement has been entered into with a
broker-dealer for the sale of shares of common stock, if required, we will file
a supplement to this prospectus. If the selling stockholders use this prospectus
for any sale of the shares of common stock, they will be subject to the
prospectus delivery requirements of the Securities Act.

      Under the securities laws of some states, the shares of common stock may
be sold in such states only through registered or licensed brokers or dealers.
In addition, in some states the shares of common stock may not be sold unless
such shares have been registered or qualified for sale in such state or an
exemption from registration or qualification is available and is complied with.

      There can be no assurance that any selling stockholder will sell any or
all of the shares of common stock registered pursuant to the shelf registration
statement, of which this prospectus forms a part.

                                     - 16 -

<PAGE>

      The selling stockholders and any other person participating in such
distribution will be subject to applicable provisions of the Securities Exchange
Act of 1934, as amended, and the rules and regulations thereunder, including,
without limitation, Regulation M of the Exchange Act, which may limit the timing
of purchases and sales of any of the shares of common stock by the selling
stockholders and any other participating person. Regulation M may also restrict
the ability of any person engaged in the distribution of the shares of common
stock to engage in market-making activities with respect to the shares of common
stock. All of the foregoing may affect the marketability of the shares of common
stock and the ability of any person or entity to engage in market-making
activities with respect to the shares of common stock.

      Once sold under the shelf registration statement, of which this prospectus
forms a part, the shares of common stock will be freely tradable in the hands of
persons other than our affiliates.

                 SELLING SECURITYHOLDER NOTICE AND QUESTIONNAIRE
