     acquire Registrable Securities or any assignee thereof in accordance with
     Section 1.12 of this Agreement;

          (e) The term "FORM F-3" means such form under the Securities Act as in

     1.2 REQUEST FOR REGISTRATION

          (a) If, at any time following the nine-month anniversary of, and until
     the seven-year anniversary of, the date of Closing of the Securities
     Purchase Agreement, the Company shall receive a written request from the
     Initiating Holders that the Company file a registration statement under the
     Securities Act covering the registration of Registrable Securities where
     the anticipated aggregate offering price, net of underwriting discounts and
     commissions, of Registrable Securities to be sold is at least $3,000,000,
     then the Company shall, within 10 days of the receipt thereof, give written
     notice of such request to all Holders and shall, subject to the limitations
     of subsection 1.2(b), use its best efforts to effect as soon as
     practicable, and in any event within one hundred and twenty (120) days of
     the receipt of such request, the registration under the Securities Act of
     all Registrable Securities which the Holders request to be registered
     within 20 days of the mailing of such notice by the Company in accordance
     with Section 3.4.

          (b) If the Initiating Holders intend to distribute the Registrable
     Securities covered by their request by means of an underwriting, they shall
     so advise the Company as a part of their request made pursuant to this
     Section 1.2 and the Company shall include such information in the written
     notice referred to in subsection 1.2(a). The underwriter will be selected
     by a majority in interest of the Initiating Holders and shall be reasonably
     acceptable to the Company. In such event, the right of any Holder to
     include his Registrable Securities in such registration shall be
     conditioned upon such Holder's participation in such underwriting and the
     inclusion of such Holder's Registrable Securities in the underwriting
     (unless otherwise mutually agreed by a majority in interest of the
     Initiating Holders and such Holder) to the extent provided herein. All
     Holders proposing to distribute their securities through such underwriting
     shall (together with the Company as provided in subsection 1.5(e)) enter
     into an underwriting agreement in customary form with the underwriter or
     underwriters selected for such underwriting. Notwithstanding any other
     provision of this Section 1.2, if the underwriter advises the Initiating
     Holders in writing that marketing factors require a limitation of the
     number of shares to be underwritten, then the Initiating Holders shall so
     advise all Holders of Registrable Securities which would otherwise be
     underwritten pursuant hereto, and the number of shares of Registrable
     Securities that may be included in the underwriting shall be allocated
     among all Holders thereof, including the Initiating Holders, in proportion
     (as nearly as practicable) to the amount of Registrable Securities of the
     Company initially sought to be registered by each Holder; PROVIDED,
     HOWEVER, that the number of shares of Registrable Securities to be included
     in such underwriting shall not be reduced unless all other securities are
     first entirely excluded from the underwriting.


                                       2
<PAGE>


          (c) Notwithstanding the foregoing, if the Company shall furnish to
     Holders requesting a registration statement pursuant to this Section 1.2, a
     certificate signed by the Chief Executive Officer of the Company stating
     that in the good faith judgment of the Board of Directors of the Company,
     it would be seriously detrimental to the Company and its stockholders for
     such registration statement to be effective at such time, the Company shall
     have the right to defer such filing for a period of not more than 120 days
     after receipt of the request of the Initiating Holders; PROVIDED, HOWEVER,
     that the Company may not utilize this right more than once in any
     twelve-month period.

          (d) In addition, the Company shall not be obligated to effect, or to
     take any action to effect, any registration pursuant to this Section 1.2:

               (i) After the Company has effected two registrations pursuant to
          this Section 1.2 and such registrations have been declared or ordered
          effective and maintained effective for at least 120 days (or less if
          the distribution contemplated in the registration statement has been
          completed);

               (ii) During the period ending (A) 12 months after the effective
          date of a registration subject to Section 1.2 hereof or (B) 180 days
          after the effective date of any other registration statement
          pertaining to Ordinary Shares of the Company, or such shorter periods
          if such shorter periods are acceptable to the underwriters of such
          offering;

               (iii) In any jurisdiction in which the Company would be required
          to execute a general consent to service of process in effecting such
          registration, qualification or compliance, unless the Company is
          already subject to service in such jurisdiction and except as may be
          required by the Securities Act or applicable rules or regulations
          thereunder; or

               (iv) If such request does not cover shares representing a market
          value at the time of such request equal to a minimum of $3,000,000.

     1.3 COMPANY REGISTRATION. If (but without any obligation to do so) at any
time until the seven-year anniversary of the date of Closing of the Securities
Purchase Agreement the Company proposes to register (including for this purpose
a registration effected by the Company for shareholders other than the Holders)
any of its shares under the Securities Act in connection with the public
offering of such securities solely for cash (other than a registration statement
on Form S-4 or S-8 or any successor forms thereto or any registration statement
filed in connection with an exchange offer of securities solely to the Company's
existing security holders), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within 20 days after mailing of such notice by the Company in
accordance with Section 3.4, the Company shall, subject to the provisions of
Section 1.8, cause to be registered under the Securities Act all of the
Registrable Securities that each such Holder has requested to be registered.

     If the Company shall receive at any time until the seven-year anniversary
of the date of Closing of the Securities Purchase Agreement a written request
from the Initiating Holders that the Company file a registration statement on
Form F-3 (or any successor form thereto) for a public offering of Registrable
Securities, the Company will:

          (a) promptly give written notice of the proposed registration to all
     other Holders; and

          (b) as soon as practicable, effect such registration and all such
     qualifications and compliances as may be so requested and as would permit
     or facilitate the sale and distribution of all or such portion of such
     Holders' Registrable Securities as are specified in such request, together
     with all or such portion of the Registrable Securities of any other Holder
     or Holders joining in such request as are specified in a written request
     given within 15 days after receipt of such written notice from the Company;
     PROVIDED, HOWEVER, that the Company shall not be obligated to effect any
     such registration, qualification or compliance, pursuant to this Section
     1.4: (i) if Form F-3 is not available for such offering by the Holders;
     (ii) if the Holders, together with the holders of any other securities of
     the Company entitled to inclusion in such registration, propose to sell
     Registrable Securities and such other securities (if any) at an aggregate
     price to the public (net of any underwriters' discounts or commissions) of
     less than $1,500,000; (iii) if the Company shall furnish to the Holders a
     certificate signed by the President of the Company stating that in the good
     faith judgment of the Board of Directors of the Company, it would be
     seriously detrimental to the Company and its stockholders for such Form F-3
     Registration to be effected at such time, in which event the Company shall
     have the right to defer the filing of the Form F-3 registration statement
     for a period of not more than 120 days after receipt of the request of the
     Holder or Holders under this Section 1.4; PROVIDED, HOWEVER, that the
     Company shall not utilize this right more than once in any twelve month
     period; (iv) if the Company has, within the twelve (12) month period
     preceding the date of such request, already effected two registrations on
     Form F-3 for the Holders pursuant to this Section 1.4; (v) in any
     particular jurisdiction in which the Company would be required to qualify
     to do business or to execute a general consent to service of process in
     effecting such registration, qualification or compliance; or (vi) during
     the period ending 90 days after the effective date of any registration
     statement pertaining to Ordinary Shares of the Company (or such shorter
     period if such shorter period is acceptable to the underwriters of such
     offering).

          (c) Subject to the foregoing, the Company shall file a registration
     statement covering the Registrable Securities and other securities so
     requested to be registered as soon as practicable after receipt of the
     request or requests of the Holders. Registrations effected pursuant to this

days) from the effective date of such registration as may be requested by the
underwriters.

     Act, with respect to which registration, qualification or compliance has
     been effected pursuant to this Agreement, and each underwriter, if any, and
     each person who controls any underwriter within the meaning of Section 15
     of the Securities Act, against all expenses, claims, losses, damages and
     liabilities (or actions in respect thereof), including any of the foregoing

     circumstances in which they were made, not misleading, (ii) any violation
     by the Company of any rule or regulation promulgated under the Securities

     omission or alleged untrue statement or omission, made in reliance upon and
     in conformity with written information furnished to the Company by an
     instrument duly executed by such Holder or underwriter and stated to be
     specifically for use therein, (ii) the failure of such Holder to provide to
     the Company information necessary for the registration statement after
     written request therefor by the Company, or (iii) the failure of such

          (b) Each Holder will, severally and not jointly, if Registrable
     Securities held by such Holder are included in the securities as to which
     such registration, qualification or compliance is being effected, indemnify
     the Company, each of its directors and officers, stockholders, employees
     and agents (including its legal counsel and independent accountants), each
     underwriter, if any, of the Company's securities covered by such a
     registration statement, each person who controls the Company or such
     underwriter within the meaning of Section 15 of the Securities Act, and
     each other such Holder, each of its officers and directors and each person
     controlling such Holder within the meaning of Section 15 of the Securities
     Act, against all claims, losses, damages and liabilities (or actions in
     respect thereof), including any of the foregoing incurred in settlement of
     any litigation, arising out of or based on (i) any untrue statement (or
     alleged untrue statement) of a material fact contained in any such
     registration statement, prospectus, offering circular or other document, or
     any omission (or alleged omission) to state therein a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, in each case to the extent, but only to the extent, that
     such untrue statement (or alleged untrue statement) or omission (or alleged
     omission) is made in such registration statement, prospectus, offering
     circular or other document in reliance upon and in conformity with written
     information furnished to the Company by an instrument duly executed by such
     Holder and stated to be specifically for use therein, (ii) any violation by
     the Company of any rule or regulation promulgated under the Securities Act
     applicable to the Company and relating to action or inaction required of
     the Company in connection with any such registration, qualification or
     compliance, in each case to the extent, but only to the extent, that such
     violation occurred solely as a result of the use, in such registration
     statement, prospectus, offering circular or other document of written
     information furnished to the Company by an instrument duly executed by such
     Holder and stated to be specifically for use therein, or (iii) provided
     that the Company has complied with its obligations under Section 1.5(c) of
     this Agreement, any failure to effectively cause the prospectus delivery
     requirement of the Securities Act to be satisfied; and each Holder will
     reimburse the Company, such Holders, such directors, officers,
     stockholders, employees and agents (including its legal counsel and
     independent accountants), underwriters or control persons for any legal or
     any other expenses reasonably incurred in connection with investigating or
     defending any such claim, loss, damage, liability or action for which such
     Holder is obligated to provide indemnification pursuant to clauses (i),
     (ii) or (iii); PROVIDED, HOWEVER, that the obligations of such Holders
     hereunder shall be limited to an amount equal to the gross proceeds before
     expenses and commissions to each such Holder of Registrable Securities sold
     as contemplated herein.

          (c) Each party entitled to indemnification under this Section 1.10
     (the "INDEMNIFIED PARTY") shall give notice to the party required to
     provide indemnification (the "INDEMNIFYING PARTY") promptly after such
     Indemnified Party has knowledge of any claim as to which indemnity may be
     sought, and shall permit the Indemnifying Party to assume the defense of
     any such claim or any litigation resulting therefrom; PROVIDED that counsel
     for the Indemnifying Party, who shall conduct the defense of such claim or
     litigation, shall be approved by the Indemnified Party (whose approval
     shall not be unreasonably withheld), and the Indemnified Party may
     participate in such defense at such party's expense; and PROVIDED FURTHER
     that the failure of any Indemnified Party to give notice as provided herein
     shall not relieve the Indemnifying Party of its obligations under this
     Agreement, except to the extent, but only to the extent, that the
     Indemnifying Party's ability to defend against such claim or litigation is
     materially adversely affected as a result of such failure to give notice.
     No Indemnifying Party, in the defense of any such claim or litigation,
     shall, except with the consent of each Indemnified Party, consent to entry
     of any judgment or enter into any settlement which does not include as an
     unconditional term thereof the giving by the claimant or plaintiff to such
     Indemnified Party of a release from all liability in respect to such claim
     or litigation.


                                       9

          (d) If the indemnification provided for in paragraphs (a) and (b) of
     this Section 1.10 is unavailable or insufficient to hold harmless an
     Indemnified Party under such paragraphs in respect of any losses, claims,
     damages or liabilities or actions in respect thereof referred to therein,
     then each Indemnifying Party shall in lieu of indemnifying such Indemnified
     Party contribute to the amount paid or payable by such Indemnified Party as
     a result of such losses, claims, damages, liabilities or actions in such
     proportion as appropriate to reflect the relative fault of the Company, on
     the one hand, and the Holders of Registrable Securities, on the other, in
     connection with the statements or omissions which resulted in such losses,
     claims, damages, liabilities or actions as well as any other relevant
     equitable considerations, including the failure to give any notice under
     paragraph (c) of this Section 1.10. The relative fault shall be determined
     by reference to, among other things, whether the untrue or alleged untrue
     statement of a material fact relates to information supplied by the
     Company, on the one hand, or the Holders of Registrable Securities, on the
     other hand, and to the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission. The Company and the Holders of Registrable Securities agree that
     it would not be just and equitable if contributions pursuant to this
     paragraph were determined by pro rata allocation (even if all of the
     Holders of Registrable Securities were treated as one entity for such
     purpose) or by any other method of allocation which did not take account of
     the equitable considerations referred to above in this paragraph. The
     amount paid or payable by an Indemnified Party as a result of the losses,
     claims, damages, liabilities or action in respect thereof, referred to
     above in this paragraph, shall be deemed to include any legal or other
     expenses reasonably incurred by such Indemnified Party in connection with
     investigating or defending any such action or claim. Notwithstanding the
     provisions of this paragraph, the Holders of Registrable Securities shall
     not be required to contribute any amount in excess of the amount of the
     total price at which the ordinary shares sold by each of them was offered
     to the public. No person guilty of fraudulent misrepresentations (within
     the meaning of Section 11(f) of the Securities Act), shall be entitled to
     contribution from any person who is not guilty of such fraudulent
     misrepresentation.

          (e) The indemnification of underwriters provided for in this Section
     1.10 shall be on such other terms and conditions as are at the time
     customary and reasonably required by such underwriters. In that event the
     indemnification of the Holders of Registrable Securities in such
     underwriting shall at the sellers' request be modified to conform to such
     terms and conditions.

     1.11 REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934

     With a view to making available to the Holders the benefits of Rule 144
promulgated under the Securities Act (or any successor provision then in effect)
and any other rule or regulation of the SEC that may at any time permit a Holder
to sell securities of the Company to the public without registration or pursuant
to a registration on Form F-3, the Company agrees to:

          (a) make and keep public information available, as those terms are
     understood and defined in SEC Rule 144 (or any successor provision then in
     effect), at all times after 90 days after the effective date of the first
     registration statement filed by the Company for the offering of its
     securities to the general public so long as the Company remains subject to
     the periodic reporting requirements under Sections 13 or 15(d) of the
     Exchange Act;

          (b) take such action, including the voluntary registration of its
     ordinary shares under Section 12 of the Exchange Act, as is necessary to
     enable the Holders to utilize Form F-3 for the sale of their Registrable
     Securities, such action to be taken as soon as practicable after the end of
     the fiscal year in which the first registration statement filed by the
     Company for the offering of its securities to the general public is
     declared effective;

          (c) file with the SEC in a timely manner all reports and other
     documents required of the Company under the Securities Act and the Exchange
     Act; and

          (d) furnish to any Holder, so long as the Holder owns any Registrable
     Securities, forthwith upon request (i) a written statement by the Company
     that it has complied with the reporting requirements of SEC Rule 144 (or
     any successor provision then in effect) (at any time after 90 days after
     the effective date of the first registration statement filed by the
     Company), the Securities Act and the Exchange Act (at any time after it has
     become subject to such reporting requirements), or that it qualifies as a
     registrant whose securities may be resold pursuant to Form F-3 (at any time
     after it so qualifies), (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 in
     availing any Holder of any rule or regulation of the SEC which permits the
     selling of any such securities without registration or pursuant to such
     form.

     1.12 ASSIGNMENT OF REGISTRATION RIGHTS

     The rights to cause the Company to register Registrable Securities under
Sections 1.2, 1.3 and 1.4 may be assigned by a Holder to a transferee or
assignee of such Registrable Securities with respect to the Registrable
Securities being assigned or transferred; PROVIDED that (a) such transfer may
otherwise be effected in accordance with applicable securities laws and
restrictions on transfer agreed upon by the Holder and the Company, (b) notice
of such assignment is given to the Company within a reasonable time (not to
exceed 20 days) after such assignment with the name and address of such assignee
and the securities with respect to which such registration rights are being
assigned, (c) such transferee or assignee (i) is a wholly-owned subsidiary or
constituent partner, retired partner, member, retired member or shareholder of
such Holder, or (ii) is an `affiliate' (as that term is defined in Rule 405
promulgated by the Commission under the Securities Act of 1933) of the Holder,
including, without limitation, where a Holder is a limited partnership, an
affiliated limited partnership managed by the same management company or
managing general partner of such Holder or an entity which controls, is
controlled by, or is under common control with, such management company or
managing general partner, or (iii) is a beneficiary of the Holder, where such
Holder is a trust or (iv) is a spouse, ancestor or descendant of such Holder, or
(v) is a trust for the benefit of such Holder or any spouse, ancestor or
descendant of such Holder, or (vi) acquires from such Holder or Holders at least
300,000 Registrable Securities (as appropriately adjusted for share splits,
share combination and the like) in a simultaneous transaction or transactions
and (d) such transferee or assignee agrees to be bound by all provisions of this
Agreement by executing a counterpart signature page hereto (which shall not be
deemed an amendment hereto). Any entity qualifying as a transferee or an
assignee pursuant to subsections (c)(i) to (iii) above is referred to herein as
a "PERMITTED TRANSFEREE").

     1.13 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS

     From and after the date of this Agreement, the Company shall not, without
the prior written consent of the holders of a majority of the Registrable
Securities, enter into any agreement with any holder or prospective holder of
any securities of the Company which would allow such holder or prospective
holder (a) to include such securities in any registration filed under Section
1.2 or Section 1.4 hereof, unless under the terms of such agreement, such holder
or prospective holder may include such securities in any such registration only
to the extent that the inclusion of his securities will not reduce the amount of
the Registrable Securities of the Holders which is included or (b) to make a
demand registration which could result in such registration statement being
declared effective within 180 days of the effective date of any registration
effected pursuant to Section 1.2.

     1.14 REGISTRABLE SECURITIES.

     For the purposes of this Agreement, Registrable Securities will cease to be
Registrable Securities when (i) a registration statement covering such
Registrable Securities has been declared effective under the Securities Act by
the SEC and such Registrable Securities have been disposed of pursuant to such
effective registration statement, (ii) the entire amount of the Registrable
Securities may be sold in a single sale, in the opinion of counsel reasonably
satisfactory to the Company, without any limitation as to volume pursuant to SEC
Rule 144 (or any successor provision then in effect), or (iii) the Registrable
Securities are proposed to be sold or distributed by a person not entitled to
the registration rights granted by this Agreement.

     2.2 SUCCESSORS AND ASSIGNS

     The terms and conditions of this Agreement shall inure to the benefit of
and be binding upon the respective successors and assigns of the parties. None
of the provisions of this Agreement may be assigned by any Shareholder other
than in connection with a due transfer of the relevant shares of the Company by
such Shareholder, provided that any right or limitation provided for the express
benefit of a specifically named Shareholder shall not be assignable by such
party other than to a Permitted Transferee of such Shareholder. The Company
shall not permit the transfer of any Registrable Securities on its books or
issue a new certificate representing any Registrable Securities unless and until
the person to whom such security is to be transferred shall have executed a
counterpart signature page hereto, pursuant to which such person becomes a party
to this Agreement and agrees to be bound by all the provisions hereof as if such

who are the owners of record of at least 75% of the Registrable Securities;
PROVIDED that (i) should such waiver or amendment adversely affect (directly or
indirectly) the rights or privileges granted hereunder to the particular Holder
or group of Holders, in a manner which discriminates such Holder/s against other
Holders (a "DISCRIMINATED CLASS"), such waiver or amendment shall be subject to
the written approval of the Holder/s who are the owners of record of a majority
of the outstanding shares of such Discriminated Class, and (ii) any right or
limitation provided for the express benefit of a specifically named party may
not be amended or waived without the consent of such party. Any amendment or
