     made on a continuous basis pursuant to Rule 415. The Registration Statement

     effective under the Securities Act as promptly as possible after the filing

     its best efforts to keep the Registration Statement continuously effective
     under the Securities Act until the earlier of (i) two years following the
     Effectiveness Date and (ii) such time as all Registrable Securities covered
     by the Registration Statement have been sold or may be sold without volume

     Company pursuant to a written opinion letter to such effect, addressed and

     2(b).

          (b) If: (i) the Registration Statement is not filed on or prior to the
     Filing Date (if the Company files the 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 the Registration Statement will not be "reviewed," or not subject to
     further review, or (iii) prior to the 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 the 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 the Registration
     Statement to be declared effective, or (iv) the Registration Statement
     filed or required to be filed hereunder is not declared effective by the
     Commission by the Effectiveness Date, or (v) after the Effectiveness Date,
     the 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 calendar
     days but no more than an aggregate of 30 calendar 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 calendar day
     period, as applicable, is exceeded being referred to as "Event Date"), then
     in addition to any other rights the Holders may have hereunder or under
     applicable law, on each such Event Date and on each monthly anniversary of
     each such Event Date (if the applicable Event shall not have been cured by
     such date) until the applicable Event is cured, the Company shall pay to
     each Holder an amount in cash, as partial liquidated damages and not as a
     penalty, equal to 1.5% 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


                                        3

<PAGE>

     payable, the Company will pay interest thereon at a rate of 18% per annum
     (or such lesser maximum amount that is permitted to be paid by applicable
     law) to the Holder, accruing daily from the date such partial liquidated
     damages are due until such amounts, plus all such interest thereon, are
     paid in full. The partial liquidated damages pursuant to the terms hereof
     shall apply on a daily pro-rata basis for any portion of a month prior to
     the cure of an Event.

     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 the
     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 the 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. 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 the Registration Statement and the
     Prospectus or, if necessary, a new Registration Statement, used in
     connection therewith as may be necessary to keep the Registration Statement
     continuously effective as to the applicable Registrable Securities for the
     Effectiveness Period and prepare and file with the Commission such
     additional Registration Statements in order to register for resale under
     the Securities Act all of the Registrable Securities; (ii) cause the
     related Prospectus to be amended or supplemented by any required Prospectus
     supplement (subject to the terms of this Agreement), and as so supplemented
     or amended to be filed pursuant to Rule 424; (iii) respond as promptly as
     reasonably possible to any comments received from the Commission with
     respect to the 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 the
     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


                                        4

<PAGE>

     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) [RESERVED].

          (d) 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 the Registration
     Statement is proposed to be filed; (B) when the Commission notifies the
     Company whether there will be a "review" of the Registration Statement and
     whenever the Commission comments in writing on the 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 the
     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
     the 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
     the 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 the Registration Statement ineligible for inclusion therein or any
     statement made in the 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 the Registration
     Statement, Prospectus or other documents so that, in the case of the
     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
     in good faith may be material and that, in the good faith determination of
     the Company, makes it not in the best interest of the Company to allow
     continued availability of the Registration Statement or Prospectus;
     provided that any and all of such information shall remain confidential to
     each Holder until such information otherwise becomes public, unless
     disclosure by a Holder is required by law; provided, further,
     notwithstanding each Holder's agreement to keep such information
     confidential, the Holders make no acknowledgement that any such information
     is material, non-public information.

          (e) Use its best efforts to avoid the issuance of, or, if issued,
     obtain the withdrawal of (i) any order suspending the effectiveness of the
     Registration Statement, or


                                        5

<PAGE>

     (ii) any suspension of the qualification (or exemption from qualification)
     of any of the Registrable Securities for sale in any jurisdiction, at the
     earliest practicable moment.

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

          (g) 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 of any notice pursuant to Section 3(d).

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

          (i) Prior to any resale of Registrable Securities by a Holder, use its
     commercially reasonable efforts to register or qualify or cooperate with
     the selling Holders in connection with the registration or qualification
     (or exemption from the Registration or qualification) of such Registrable
     Securities for the resale by the Holder under the securities or Blue Sky
     laws of such jurisdictions within the United States of America 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 the Registration Statement; provided, that the Company shall not
     be required to qualify generally to do business in any jurisdiction where
     it is not then so qualified, subject the Company to any material tax in any
     such jurisdiction where it is not then so subject or file a general consent
     to service of process in any such jurisdiction.

          (j) If requested by the Holders, cooperate with the Holders to
     facilitate the timely preparation and delivery of certificates representing
     Registrable Securities to be delivered to a transferee pursuant to the
     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.


                                        6

<PAGE>

          (k) Upon the occurrence of any event contemplated by this Section 3,
     as promptly as reasonably possible under the circumstances taking into
     account the Company's good faith assessment of any adverse consequences to
     the Company and its stockholders of the premature disclosure of such event,
     prepare a supplement or amendment, including a post-effective amendment, to
     the 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 the 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(d) above to suspend the use of any Prospectus until the
     requisite changes to such Prospectus have been made, then the Holders shall
     suspend use of such Prospectus. The Company will use its best efforts to
     ensure that the use of the Prospectus may be resumed as promptly as is
     practicable. The Company shall be entitled to exercise its right under this
     Section 3(k) to suspend the availability of the Registration Statement and
     Prospectus, subject to the payment of partial liquidated damages pursuant
     to Section 2(b), for a period not to exceed 60 days (which need not be
     consecutive days) in any 12 month period.

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

          (m) The Company may require each selling Holder to furnish to the
     Company a certified statement as to the number of shares of Common Stock
     beneficially owned by such Holder and, if required by the Commission, the
     person thereof that has voting and dispositive control over such 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 pursuant to Section 2(b) hereof 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 the
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

under the laws of such jurisdictions as requested by the Holders) and (C) if not

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


                                        7

<PAGE>

no more than a customary brokerage commission in connection with such sale, (ii)

     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, but only 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 the Registration Statement or such Prospectus
     or (ii) to the extent, but only to the extent, (1) that 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 the 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(d)(ii)-(vi),
     of the use by such Holder of an outdated or defective Prospectus after the
     Company has notified such Holder in writing that the Prospectus is outdated
     or defective and prior to the receipt by such Holder of the Advice
     contemplated in Section 6(d). In no event shall the liability of any
     selling Holder hereunder be greater in amount than the dollar amount of the
     net proceeds received by such Holder upon the sale of the Registrable
     Securities giving rise to such indemnification obligation.

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


                                        9

<PAGE>

          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 legal counsel for 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). 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, conditioned or delayed. No Indemnifying Party shall,
     without the prior written consent of the Indemnified Party, effect any
     settlement of any pending Proceeding in respect of which any Indemnified
     Party is a party, unless such settlement includes an unconditional release
     of such Indemnified Party from all liability on claims that are the subject
     matter of such Proceeding.

          Subject to the terms of this Agreement, all reasonable fees and
     expenses of the Indemnified Party (including reasonable fees and expenses
     to the extent incurred in connection with investigating or preparing to
     defend such Proceeding in a manner not inconsistent with this Section)
     shall be paid to the Indemnified Party, as incurred, within ten Trading
     Days of written notice thereof to the Indemnifying Party; provided, that
     the Indemnified Party shall promptly reimburse the Indemnifying Party for
     that portion of such fees and expenses applicable to such actions for which
     such Indemnified Party is 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 as a
     result of such Losses, in such proportion as is appropriate to reflect the
     relative fault of the Indemnifying Party and Indemnified Party in
     connection with the actions, statements or omissions that resulted in such
     Losses as well as any other relevant equitable considerations. The relative
     fault of such Indemnifying Party and Indemnified Party shall be determined
     by reference to, among other things, whether any action in question,
     including any untrue or alleged untrue statement of a material fact or
     omission or alleged omission of a material fact, has been taken or made by,
     or relates to information supplied by, such Indemnifying Party or
     Indemnified Party, and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such action, statement or
     omission. The amount paid or payable by a party as a result of any Losses
     shall be deemed to include, subject to the limitations set forth in this
     Agreement, any reasonable attorneys' or other reasonable fees


                                       10

<PAGE>

     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 Registration Statement other than the
     Registrable Securities. Other than the Holders, 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 Registration Statement required hereunder
     is declared effective by the Commission, provided that this Section 6(b)
     shall not prohibit the Company from filing any registration statement on
     Form F-1 or F-4 in connection with the merger between the Company and
     Shellco or amendments to registration statements already filed.

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


                                       11

<PAGE>

          (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(d), such
     Holder will forthwith discontinue disposition of such Registrable
     Securities under the 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 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 F-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 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.


                                       12

<PAGE>

          (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(i),
     neither the Company nor any of its subsidiaries has previously entered into
     any agreement granting any registration rights with respect to any of its
     securities to any Person that have not been satisfied in full.

          (j) Execution and Counterparts. This Agreement may be executed in 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 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.

          (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


                                       13

<PAGE>

     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 Euroseas Ltd., a Marshall Islands 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:

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

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

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

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

          -    privately negotiated transactions;

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

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

          -    a combination of any such methods of sale;

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

          -    any other method permitted pursuant to applicable law.

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

     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


                                       17

<PAGE>

commission in compliance with NASDR Rule 2440; and in the case of a principal
transaction a markup or markdown in compliance with NASDR IM-2440.

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

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

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

     Because Selling Stockholders may be deemed to be "underwriters" within the
meaning of the Securities Act, they will be subject to the prospectus delivery
requirements of the Securities Act. In addition, any securities covered by a
prospectus which qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than under a prospectus. Each Selling
Stockholder has advised us that it has not entered into any written or oral
agreements, understandings or arrangements with any underwriter or broker-dealer
regarding the sale of the Common Stock. There is no underwriter or coordinating
broker acting in connection with the proposed sale of the Common Stock by the
Selling Stockholders.

     We agree to keep a 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 Common Stock will be
sold only through registered or licensed brokers or dealers if required under
applicable state securities laws. In addition, in certain states, the Common
Stock may not be sold unless it has been registered or


                                       18

<PAGE>

qualified for sale in the applicable state or an exemption from the registration
or qualification requirement is available and is complied with.

     Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the Common Stock 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 any prospectus
available to the Selling Stockholders and have informed them of the need to
deliver a copy of a prospectus to each purchaser at or prior to the time of the
sale.

                                  EUROSEAS LTD.

                 SELLING SECURITYHOLDER NOTICE AND QUESTIONNAIRE

     The undersigned beneficial owner of common stock, par value $.01 per share
(the "Common Stock"), of Euroseas Ltd., a Marshall Islands corporation (the
"Company"), (the "Registrable Securities") understands that the Company has
filed or intends to file with the Securities and Exchange Commission (the
"Commission") a registration statement on Form F-1 (the "Registration
Statement") for the registration and resale under Rule 415 of the Securities Act
of 1933, as amended (the "Securities Act"), of the Registrable Securities, in
accordance with the terms of the Registration Rights Agreement, dated as of
August [____, 2005 (the "Registration Rights Agreement"), among the Company and
the Purchasers named therein. A copy of the Registration Rights Agreement is
available from the Company upon request at the address set forth below. All
capitalized terms not otherwise defined herein shall have the meanings ascribed
thereto in the Registration Rights Agreement.

     Certain legal consequences arise from being named as a selling
securityholder in the Registration Statement and the related prospectus.
Accordingly, holders and beneficial owners of Registrable Securities are advised
to consult their own securities law counsel regarding the consequences of being
named or not being named as a selling securityholder in the Registration
