cause Parent to register such Shareholders' Parent Shares (as defined herein)
for distribution to the public.

inducement to, and in consideration of, Parent's willingness to consummate the
transactions contemplated by the Merger Agreement.

    Registration"). Upon the written request of a Strategic Partner made to
    Parent within 15 business days of the receipt of such notice from Parent,
    Parent shall include in such Company Registration the requested number of
    Parent Shares held by such Strategic Partner (complying with the provisions
    of this Article 5) all in accordance with and subject to the terms of this
    Agreement.

       one of the Strategic Partners has exercised its Registration Rights in
       accordance with Article 4, Article 5 or Article 9 hereof, as the case may
       be, to include Parent Shares in such Company Registration, Parent shall
       furnish prompt (but in any event no later than 25 days prior to the
       filing of the applicable Registration Statement) written notice to each
       of the Tantau Shareholders of its intention to effect such a Company
       Registration and the intended method of distribution in connection
       therewith. Such notice shall offer the Tantau Shareholders the
       opportunity to qualify or register (on the same terms and conditions) all
       or part of the Parent Shares that were issued to each of them in
       connection with the Merger (subject to Section 6.1(b)) the transfer of
       which is not then prohibited by the Resale Restriction Agreement
       (collectively, "Tantau Qualified Parent Shares"), subject to the
       provisions of this Agreement (in this Article 6, a "Piggyback
       Registration"). Upon the written request of a Tantau Shareholder made to
       Parent within 15 business days after the receipt of such notice by
       Parent, Parent shall include in such Company Registration the requested
       number of Tantau Qualified Parent Shares, subject to the provisions
       hereof and other customary terms, conditions and limitations relating to
       the registration of securities generally.

    (b) Notwithstanding the foregoing, Parent shall not be required to register
       any Tantau Qualified Parent Shares the transfer of which is restricted by
       the terms of the Resale Restriction Agreement, or that are held in escrow
       in accordance with the Escrow Agreement (as that term is defined in the
       Merger Agreement), provided however that, if a Company Registration is
       effected prior to the day which is three months from the Effective Time
       (as defined in the Merger Agreement), the Tantau Shareholders may request
       that Parent include up to 15% of such Tantau Shareholder's Tantau
       Qualified Parent Shares in such Company Registration. In the event that a
       Tantau Shareholder makes such a request, the number of Tantau Qualified
       Parent Shares that are ultimately included in such Company Registration
       shall be deducted from the number of Tantau Qualified Parent Shares
       released from the Resale Restriction (as defined in the Resale
       Restriction Agreement) after the Three Month Reference Date (as defined
       in and in accordance with Section 2(b)(i) of the Resale Restriction
       Agreement).

    (c) If, in the opinion of counsel to Parent, the Tantau Qualified Parent
       Shares are not permitted to be included in a Company Registration in
       accordance with Section 6.1(a) hereof, either because of the rules and
       regulations of an applicable Securities Regulator, or because of written
       or oral directives of an applicable Securities Regulator to such effect,
       then Parent shall use reasonable efforts to cause the lead managing
       underwriter(s) of the offering to offer and sell the Tantau Qualified
       Parent Shares concurrently with, and at the same price and terms as
       applicable to, the sale of Parent Shares by the Founding Shareholder
       and/or Strategic Partner(s) that are participating in such Company
       Registration. Parent shall not be deemed to breach this Agreement if it
       effects such Registration notwithstanding the refusal of the lead
       managing underwriter(s) of the offering to take the actions described in
       the previous sentence. If an applicable Securities Regulator precludes or
       imposes substantial disclosure requirements with respect to the inclusion
       of the Tantau Qualified Parent Shares in such offering, then Parent will
       be deemed to have used reasonable efforts without further requirement
       that the Tantau Qualified Parent Shares be so included in the
       underwritten offering.

    (d) For the purposes of Section 6.1(c) hereof, the Tantau Shareholders shall
       use the same underwriter used by Parent for the offering in question, and
       shall cooperation and coordinate

                                       13
<PAGE>
       their efforts in good faith with those of Parent with a view to avoiding
       disruption or regulatory impediments to the Company Registration.

6.2 TERMINATION OF REGISTRATION RIGHTS

    All rights granted to the Tantau Shareholders pursuant to Section 6.1 shall
    terminate with respect to any Tantau Qualified Parent Shares held by a
    Tantau Shareholder upon the earliest to occur of (i) January 27, 2004, being
    the date which is four years from Parent's initial public offering;
    (ii) the acquisition of the Tantau Qualified Parent Shares by any person
    from a Tantau Shareholder in accordance with Section 12.2(c) hereof; or
    (iii) the Tantau Shareholder in question then holds: (x) with respect to the
    90 day period commencing on the date hereof, less than 50,000 Tantau
    Qualified Parent Shares; or (y) with respect to the period thereafter, less
    than 300,000 Tantau Qualified Parent Shares.

                                   ARTICLE 7
                  RULES RELATING TO DEMAND REGISTRATION RIGHTS

7.1 CONTENTS OF DEMAND REGISTRATION REQUEST

    (a) Any request for a Demand Registration shall specify the number of
       securities proposed to be sold by the Initiating Party(ies) and the
       intended method of disposition thereof (i.e. registration only, "best
       efforts" or firm underwriting). Parent shall not be obligated to effect a
       Demand Registration unless the Demand Registration is in respect of at
       least the lesser of: (i) 1,000,000 Parent Shares; and (ii) 25% of the
       Parent Shares then held by the Initiating Party(ies).

    (b) A Demand Registration shall not require a shelf registration or a shelf
       prospectus.

7.2 MINIMUM OFFERING SIZE FOR DEMAND REGISTRATION

    Notwithstanding the initiation of a Demand Registration, and in addition to
    the limitations set forth in Section 7.1(a), Parent shall not be obligated
    to effect such Demand Registration if:

    (a) Parent determines, after consultation with the proposed underwriters for
       the offering, that the aggregate expected gross proceeds in respect of:
       (i) the Parent Shares requested to be included in an offering pursuant to
       a Registration Request; and (ii) the Parent Shares and/or the Tantau
       Qualified Parent Shares requested to be included in such offering
       pursuant to the exercise of Piggyback Registration rights under
       Sections 4.2, 5.2 or 6.1 hereof, as the case may be, will be less than US
       $20,000,000 (the "Minimum Threshold"), unless the Initiating Party(ies)
       agree(s) to sell additional securities (to the extent that it retains any
       securities of Parent) to make up the deficiency; or

    (b) pursuant to the advisement of the lead managing underwriter(s) as
       contemplated in Section 10.2(b), there is a reduction in the number of
       Parent Shares (inclusive of all shares being sold in the offering by
       Parent and the Shareholders) to be included in the offering such that the
       reduced number of Parent Shares would not generate proceeds that are
       equal to or that exceed the Minimum Threshold;

    provided, however, that if the Initiating Party(ies) are proposing to sell
    all of their remaining securities of Parent, the Minimum Threshold
    requirement shall not apply. In addition, subject to the immediately
    preceding sentence, if a Demand Registration is not implemented because the
    Minimum Threshold has not been met, the Initiating Party(ies) shall be
    entitled to re-initiate such requested Demand Registration at a later time
    in accordance with the provisions of this Agreement.

                                       14
<PAGE>
7.3 NO OBLIGATION TO EFFECT DEMAND REGISTRATION RIGHT

    Notwithstanding anything to the contrary contained in this Agreement:

    (a) Parent shall not be obligated to effect a Founding Shareholder Demand
       Registration if, as of the date that such demand is delivered to the
       Company, the Founding Shareholder had the opportunity to utilize its
       Piggyback Registration rights in connection with a Registration of Parent
       Shares that became effective within the immediately preceding six month
       period and did not at that time exercise such rights by a request to have
       included in such Piggyback Registration at least 100,000 Parent Shares
       (it being acknowledged that as a result of the priority allocation rules
       contained herein, such request might not have been honored in full);

    (b) Parent shall not be obligated to effect any Demand Registration: (i) if
       Parent has, within the nine month period immediately preceding the
       delivery of the Registration Request, already caused a Registration
       Statement relating to a Demand Registration for the Initiating Party(ies)
       to be declared effective; or (ii) in any jurisdiction in which Parent
       would be required to qualify generally to do business or to execute a
       general consent to service of process in effecting such Registration,
       except to the extent required by applicable law of Canada, the United
       States or a political subdivision thereof in connection with the
       particular offering; and

    (c) Parent shall not be obligated to effect, or to take any action to
       effect, any Demand Registration: (i) during the period starting with the
       date 60 days prior to Parent's good faith estimate of the date of filing
       of, and ending on a date 180 days after the effective date of, a Company
       Registration; provided that Parent is actively employing in good faith
       all reasonable efforts to cause such Registration Statement to become
       effective; or (ii) if the Initiating Party(ies) proposes to dispose of
       Parent Shares that may be distributed pursuant to a Short-Form Offering
       pursuant to a request made pursuant to Article 9 hereof.

7.4 ABILITY OF PARENT TO SUSPEND A DEMAND REGISTRATION

    In addition, if, in connection with a Registration Request, Parent shall, no
    later than five days prior to the effectiveness of a Registration Statement,
    furnish to the Initiating Party(ies), a certificate signed by the Chief
    Financial Officer of Parent stating that, in the good faith judgment of the
    Board of Directors of Parent, it would be seriously detrimental to Parent
    and its shareholders to file a Registration Statement pursuant to such
    Registration Request and it is therefore essential to defer the filing of
    such Registration Statement, Parent shall have the right to defer taking
    action with respect to such filing for a period of not more than 120 days
    after receipt of the Registration Request of the Initiating Party(ies);
    provided, however, that Parent may utilize this right only once in respect
    of a Founding Shareholder Demand Registration and only once in respect of a
    Strategic Partner Demand Registration.

7.5 ASSIGNMENT OF FOUNDING SHAREHOLDER AND STRATEGIC PARTNER REGISTRATION RIGHTS

    (a) The Founding Shareholder shall be entitled to assign its Registration
       Rights relating to any of its Parent Shares being sold to any person
       (without prejudice to the Registration Rights attaching to the Parent
       Shares that the Founding Shareholder continues to hold), provided,
       however that:

        (i) the Founding Shareholder Demand Registration rights under
            Section 4.1 hereof may only be assigned in whole, and not in part,
            and the Founding Shareholder shall not retain any part of the
            Founding Shareholder Demand Registration rights once they have been
            assigned;

        (ii) the Founding Shareholder Piggyback Registration rights under
             Section 4.2 hereof may only be assigned if the purchaser of its
             Parent Shares acquires at least 5% of the issued and outstanding
             equity shares of Parent at the date of the transaction pursuant to
             which

                                       15
<PAGE>
             such purchaser first becomes a Shareholder and such Piggyback
             Registration rights may be exercised by such assignee as if it was
             a member of the Founding Shareholder (including in conjunction with
             the exercise of a Founding Shareholder Demand Registration);

       (iii) Parent is, within a reasonable time after such transfer, furnished
             with written notice of the name and address of such transferee or
             assignee and the securities with respect to which such registration
             rights are being assigned; and

        (iv) such transferee or assignee agrees in writing to be bound by and
             subject to the terms and conditions of this Agreement.

       For greater certainty, subject to Section 12.1(c) hereof, any assignee of
       the Founding Shareholder Registration Rights under this Section 7.5(a)
       shall have the same rights and benefits, and shall be subject to the same
       limitations and restrictions, applicable to the Founding Shareholders
       hereunder including, without limitation, Sections 4.4 and 9.4 hereof and
       the 300,000 Parent Shares threshold below which the Founding
       Shareholder's Piggyback Registration rights expire.

    (b) Subject to Section 12.2 and this Section 7.5(b), the Strategic Partner
       Demand Registration rights are meant to be exercised, collectively, by
       all Strategic Partners from time to time and no interest therein may
       accrue to the benefit of or be exercised by any other person. Any person
       who acquires from one or more Strategic Partners in a particular
       transaction (or series of related transactions) at least 5% of the
       outstanding equity shares of Parent at the date of such acquisition,
       accompanied by an assignment of Registration Rights hereunder in
       accordance with Section 12.2 hereof, shall be entitled to participate in
       a Strategic Partner Demand Registration under Article 5 hereof and a
       Short-Form Offering Registration initiated by a Strategic Partner under
       Article 9, and to exercise the Piggyback Registration rights under
       Article 5, as if it was a Strategic Partner (including in conjunction
       with the exercise of a Strategic Partner Demand Registration), provided
       that, subject to Section 12.1(c), any such person shall have the same
       rights and benefits, and shall be subject to the same limitations and
       restrictions applicable to Strategic Partners hereunder including,
       without limitation, Sections 5.4 and 9.4 hereof and the 300,000 Parent
       Shares threshold below which a Strategic Partner's Piggyback Registration
       rights expire.

    For greater certainty, subject to the provisions of the Agreement
    (including, without limitation, Section 5.4 and 9.4 hereof), the
    Registration Rights of a Strategic Partner hereunder shall remain unaffected
    and in full force and effect with respect to such Strategic Partner's
    remaining Parent Shares in the event of such an acquisition by a person of
    at least 5% of the outstanding equity shares of Parent.

                                   ARTICLE 8
                   PRIORITIES RELATING TO REGISTRATION RIGHTS

8.1 PRIORITIES FOR OFFERINGS INITIATED BY PARENT

    If a proposed Piggyback Registration relates to an underwritten primary
    registration on behalf of Parent and the lead managing underwriter(s)
    advises Parent in writing that, in its opinion, the number of Registrable
    Securities requested to be included in the Registration (inclusive of the
    securities proposed to be sold by Parent) exceeds the number which can be
    sold in such offering without adversely affecting the price of the
    Registrable Securities to be sold, then Parent shall include in such
    Registration, in order of priority: (i) first, the securities Parent
    proposes to sell; (ii) second, all (or a portion, as the case may be) of the
    Registrable Securities requested to be included in such Piggyback
    Registration by the Founding Shareholder, the Strategic Partners and the
    Tantau Shareholders, PRO RATA based upon the number of Registrable
    Securities requested by

                                       16
<PAGE>
    them to be included in such Piggyback Registration, except to the extent any
    of them may agree to a lower priority; and (iii) third, other securities of
    Parent requested to be included in such Registration.

8.2 PRIORITIES FOR OFFERINGS INITIATED BY THE FOUNDING SHAREHOLDER OR THE
    STRATEGIC PARTNERS

    If a Demand Registration relates to an underwritten offering and the lead
    managing underwriter(s) advise(s) Parent in writing that, in its opinion,
    the number of Registrable Securities requested to be included in such
    Registration (inclusive of all proposed Piggyback Registrations) exceeds the
    number which can be sold in such offering without adversely affecting the
    price of the Registrable Securities to be sold, then Parent shall include in
    such Registration, in order of priority: (i) first, securities Parent wishes
    to sell, to the extent of gross proceeds of US$25,000,000; (ii) second, all
    or a portion (as the case may be) of the Registrable Securities requested to
    be included in such offering by the Founding Shareholder and the Strategic
    Partners (whether pursuant to their Demand Registration Rights or their
    Piggyback Registration rights) and the Tantau Shareholders (pursuant to
    their Piggyback Registration rights), PRO RATA based upon the number of
    Registrable Securities requested by them to be included in such
    Registration, except to the extent any of them may agree to a lower
    priority; (iii) third, the balance of the securities Parent proposes to
    sell, if any; and (iv) fourth, other securities of Parent requested to be
    included in such Registration; provided, however, that if Parent's exercise
    of its priority causes the number of shares registrable by the Initiating
    Party(ies) to be reduced by more than 25%, then such Registration shall not
    be counted as a Registration for purposes of Sections 4.1, 5.1 or 9.3, as
    the case may be, and the Initiating Party(ies) shall retain its/their rights
    with respect to such Demand Registration.

8.3 PRIORITIES FOR OFFERINGS INITIATED BY A THIRD PARTY

    If a Piggyback Registration relates to an underwritten secondary offering on
    behalf of holders of Parent Shares (other than the Founding Shareholder
    under Article 4 or the Strategic Partners under Article 5 or the Tantau
    Shareholders under Article 6) and the lead managing underwriter(s) advise(s)
    Parent in writing that, in its opinion, the number of Registrable Securities
    requested to be included in such Registration (inclusive of all proposed
    Piggyback Registrations) exceeds the number which can be sold in such
    offering without adversely affecting the price of the Registrable Securities
    to be sold, then Parent shall include in such Registration, in order of
    priority: (i) first, securities Parent wishes to sell, to the extent of
    gross proceeds of US$25,000,000; (ii) second, the securities proposed to be
    sold by the sellers on whose behalf the offering was initiated;
    (iii) third, all or a portion (as the case may be) of the Registrable
    Securities requested to be included in such offering by the Founding
    Shareholder, the Strategic Partners and the Tantau Shareholders PRO RATA
    based upon the number of Registrable Securities requested by them to be
    included in such Registration, except to the extent any of them may agree to
    a lower priority; (iv) fourth, the balance of the securities Parent proposes
    to sell, if any; and (v) fifth, other securities of Parent requested to be
    included in such Registration.

                                   ARTICLE 9
                   FORM S-3, F-3, SHORT-FORM F-10, FORM S-10
                    AND SHORT-FORM PROSPECTUS REGISTRATIONS

9.1 PARENT'S OBLIGATIONS

    With a view to making available to the Founding Shareholder and the
    Strategic Partners acting collectively (each an "S-3 Seller") the benefits
    of Rule 144 promulgated under the Securities Act and any other rule or
    regulation of the U.S. Securities Regulator that may at any time permit an
    S-3 Seller to sell securities of Parent to the public without registration
    or pursuant to a registration on Form S-3, Form F-3, a short-form prospectus
    using Form F-10 and Form S-10 or other similar

                                       17
<PAGE>
    simplified offering documents under the applicable U.S. Securities Laws or
    the benefits of a short-form prospectus or similar simplified offering
    document pursuant to the National Policy No. 47 "Prompt Offering
    Qualification System" and, once in force, National Instrument 44-101 and
    analogous rules and policies applicable under Canadian Securities Laws
    (collectively, "Short-Form Offerings"), Parent agrees to:

    (a) make and keep public information available and current, as those terms
       are understood and defined in Rule 144(c) promulgated under the
       Securities Act, at all times that any party hereto may still exercise its
       registration rights hereunder;

    (b) take such action, including the filing of such reports and other
       documents as may be required under Section 12 of the Exchange Act, as is
       necessary to enable the S-3 Sellers to utilize Short-Form Offerings for
       the sale of Parent Shares, such action to be taken as soon as practicable
       after December 31, 2000 (the end of the fiscal year in which the first
       Registration Statement filed by Parent for the offering of its securities
       to the general public in the United States was declared effective);

    (c) file with the U.S. Securities Regulator in a timely manner all reports
       and other documents required to be filed by Parent under Sections 13, 14
       or 15(d) under the Exchange Act;

    (d) furnish to any S-3 Seller, so long as it owns any Parent Shares,
       forthwith upon request: (i) a written statement by Parent that it has
       complied with the reporting requirements of Rule 144(c) promulgated under
       the Securities Act (at any time that any party hereto may still exercise
       its Registration Rights hereunder) 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 a
       Short-Form Offering (at any time after it so qualifies); (ii) a copy of
       the most recent annual or quarterly report of Parent and such other
       reports and documents so filed by Parent pursuant to the Exchange Act;
       and (iii) such other information as may be reasonably requested in
       availing any S-3 Seller of any rule or regulation of the U.S. Securities
       Regulator or U.S. Securities Laws which permits the selling of any such
       securities without registration or pursuant to such simplified
       Registration Statements; and

    (e) file with the Canadian Securities Regulators an Annual Information Form
       under the "Prompt Offering Prospectus System" (and, once in force,
       National Instrument 44-101) and thereafter file renewal Annual
       Information Forms and all required continuous disclosure and other
       documents required for Parent to make use of the "Prompt Offering
       Qualification System" as soon as it is otherwise eligible to do so (in
       which case the provisions of this Article 9 shall apply MUTATIS
       MUTANDIS).

9.2 SHORT-FORM REGISTRATION

    In case Parent shall receive from an S-3 Seller a written request or
    requests that Parent effect the qualification of, or registration for, a
    Short-Form Offering and any related qualification or compliance with respect
    to all or a portion of the Parent Shares owned by the proposed S-3 Seller,
    Parent will:

    (a) promptly give written notice of the proposed Registration, and any
       related qualification or compliance, to the Founding Shareholder, the
       Strategic Partners and the Tantau Shareholders; and

    (b) as soon as practicable, effect such qualification or registration and
       all such qualifications and compliance as may be so requested and as
       would permit or facilitate the sale and distribution of all or such
       portion of the proposed S-3 Seller's Parent Shares as are specified in
       such request, together with all or such portion of the Parent Shares of
       any other Shareholder joining in such request as are specified in a
       written request given within 15 days after receipt of such written notice
       from Parent.

                                       18
<PAGE>
9.3 LIMITS TO PARENT'S OBLIGATION TO EFFECT A SHORT-FORM REGISTRATION

    Parent shall not be obligated to effect any such Registration pursuant to
    this Article 9:

    (a) if the initiating S-3 Seller is not eligible for a Short-Form Offering;

    (b) if the initiating S-3 Seller, together with the holders of any other
       equity securities of Parent entitled to inclusion in such Registration,
       propose to sell Parent Shares at an aggregate price to the public (net of
       any underwriters' discounts or commissions) of less than
       U.S. $15,000,000;

    (c) if Parent shall, no later than five days prior to the effectiveness of
       such Registration, furnish to the initiating S-3 Seller a certificate
       signed by the Chief Financial Officer of Parent stating that, in the good
       faith judgement of the Board of Directors of Parent, it would be
       seriously detrimental to Parent and its shareholders for such Short-Form
       Offering Registration to be effected at such time, in which event Parent
       shall have the right to defer the filing of the Short-Form Offering
       Registration Statement for a period of not more than 60 days after
       receipt of the request of the initiating S-3 Seller; provided, however,
       that Parent shall not utilize this right more than once in any 12 month
       period;

    (d) if Parent has, within the 180 day period immediately preceding the
       request of the initiating S-3 Seller, caused a Registration Statement
       (for greater certainty including a Short-Form Offering) to be declared
       effective;

    (e) in any particular jurisdiction in which Parent 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
       except to the extent required by applicable law of Canada, the United
       States or a political subdivision thereof in connection with the
       particular offering; or

    (f) pursuant to a shelf registration or a shelf prospectus.

9.4 EXPIRY OF SHORT-FORM REGISTRATION RIGHTS

    Notwithstanding any of the foregoing provisions, Parent shall not be
    required to effect registration pursuant to this Article 9:

    (a) if the request of the S-3 Seller is made at any time after January 27,
       2004, being the date which is four years from Parent's initial public
       offering; or

    (b) if, with respect to S-3 Seller: (I) such securities have become freely
       tradable pursuant to Rule 144 promulgated under the Securities Act
       (i.e. are no longer subject to the volume and manner of sale restrictions
       applicable to "affiliates" of Parent (within the meaning of the
       U.S. Securities Laws), and have become freely tradable upon the
       expiration of any otherwise applicable hold period under Canadian
       Securities Laws (or any similar provision under applicable Securities
       Laws); and (II) an offering of such securities would not be deemed to
       constitute a "distribution" within the meaning of clause (c) of
       Subsection 1(1) of the Securities Act (Ontario) (or equivalent provisions
       of Canadian securities laws); and (III) the applicable S-3 Seller holds
       less than 2.5% of the issued and outstanding equity shares of Parent at
       the date of the request.

    (c) Subject to the foregoing, Parent shall file a Registration Statement
       covering the Parent Shares so requested as soon as practicable after
       receipt of the request of the initiating S-3 Seller. All Registration
       Expenses incurred in connection with a registration requested pursuant to
       this Article 9, including (without limitation) all registration, filing,
       qualification, printer's and accounting fees and the reasonable fees and
       disbursements of one United States and one Canadian counsel for the
       initiating S-3 Seller or other Selling Shareholder(s) in addition to
       counsel for Parent, but excluding any underwriters' discounts or
       commissions associated with such disposition of Parent Shares, shall be
       paid by Parent.

    The provisions of Articles 7, 8, 10, and 11 shall apply, MUTATIS MUTANDIS,
    to such Short Form Offerings.

                                   ARTICLE 10
               GENERAL PROVISIONS RELATING TO REGISTRATION RIGHTS

10.1 CONDITIONS PRECEDENT TO PARENT'S OBLIGATIONS

    It shall be a condition precedent to the obligation of Parent to include any
    Registrable Securities in a Registration Statement pursuant this Agreement
    that a Selling Shareholder shall furnish to Parent such information
    regarding itself, the Registrable Securities held by it, and the intended
    method of disposition of such securities as shall be reasonably requested in
    writing by Parent and required pursuant to the Securities Laws to effect the
    Registration of the Registrable Securities held by such Selling Shareholder.
    Any such information, or any comments on any such information included in a
    draft of a Registration Statement provided to such Selling Shareholder for
    its comment, shall be provided to Parent within any reasonable time period
    requested by Parent.

10.2 PARTICIPATION IN UNDERWRITTEN REGISTRATION

    (a) A Selling Shareholder shall not participate in any underwritten
       Registration hereunder and Parent shall not be required to register any
       of Shareholder's Registrable Securities in connection with such an
       underwritten Registration unless such Selling Shareholder: (i) agrees to
       sell such Selling Shareholder's Registrable Securities on the basis
       provided in any underwriting arrangements approved by the person or
       persons entitled hereunder to approve such arrangements; (ii) accepts the
       underwriters selected by Parent; (iii) subject to sections 10.5 and 10.6
       below, executes an underwriting agreement with such underwriters
       containing provisions that are customary in an underwritten Registration
       (including a market stand-off agreement consistent with, and subject to
       the restrictions applicable to, the terms of Section 10.11 hereof, if
       required by such underwriters) that includes Parent Shares held by a
       Shareholder; and (ii) completes and executes all questionnaires, powers
       of attorney, indemnities, escrow agreements and other documents
       reasonably required and which are acceptable to such Selling Shareholder
       acting reasonably and in good faith under the terms of such underwriting
       arrangements and consistent with the provisions of this Agreement.

    (b) Registrable Securities shall be sold in such underwritten Registration
       only in such quantity as the lead managing underwriter(s) determine(s),
       in its sole discretion, will not jeopardize the success of the offering
       by Parent. To the extent that the lead managing underwriter(s) advised
       Parent in writing that, in its opinion, the number of securities proposed
       to be included in the offering exceeds the number that can be sold in
       such offering without adversely affecting the price of the securities to
       be sold, then the securities to be included shall be apportioned in
       accordance with the priorities described in Article 8. If a Selling
       Shareholder disapproves of the terms of any such underwriting, such
       Selling Shareholder may elect to withdraw therefrom by written notice to
       Parent and the underwriter(s), delivered at least five business days
       prior to the effective date of the Registration Statement. Any
       Registrable Securities excluded or withdrawn from such underwriting shall
       be excluded and withdrawn from the Registration.

    (c) If by the withdrawal of such Registrable Securities a greater number of
       Registrable Securities held by other Shareholders may be included in such
       Registration up to the maximum of any limitation imposed by the lead
       managing underwriter(s), then Parent shall offer to all Shareholders who
       have included Registrable Securities in the registration or to all, if
       any, whose Parent Shares have been excluded from the registration by
       Article 8 the right to include additional Registrable Securities in the
       same proportion used in determining priorities under Article 8.

10.3 REGISTRATION EXPENSES

    (a) Unless prohibited by applicable law, all Registration Expenses will be
       borne by Parent; provided, however, that Parent shall not be required to
       pay for any expenses of any Registration or prospectus process initiated
       pursuant to a Demand Registration if the Registration Request is
       subsequently withdrawn at the request of the Initiating Party, in which
       case, the particular Shareholder whose withdrawal resulted in the
       withdrawal of the Registration Request shall reimburse Parent for all
       such expenses, unless at the time of such withdrawal the Initiating Party
       indicates that since the date of the Registration Request, it has learned
       of a material adverse change of the condition, business or prospects of
       Parent from that known to the Initiating Party at the time of the
       Registration Request and provided that the Initiating Party withdraws the
       request with reasonable promptness following disclosure by Parent of such
       material adverse change (whereupon the Initiating Party shall not be
       required to pay any of such Registration Expenses).

    (b) All Selling Expenses will be borne by the Selling Shareholders PRO RATA
       on the basis of the number of shares Registered.

10.4 PARENT'S OBLIGATIONS

    If and whenever Parent is required to effect the Registration of any
    Registrable Securities under the applicable Securities Laws pursuant to this
    Agreement, Parent will, as expeditiously as possible:

    (a) prepare and file with the Securities Regulators the requisite
       Registration Statement to effect such Registration and thereafter use its
       best efforts to cause such Registration Statement to become effective;

    (b) prepare and file with the Securities Regulators such amendments and
       supplements to such Registration Statement as may be necessary to keep
       such Registration Statement effective (subject to the provisions of
       Section 7.1(b)) and to comply with the provisions of the applicable
       Securities Laws with respect to the disposition of all Registrable
       Securities offered by such Registration Statement until such time as all
       of such Registrable Securities have been disposed of in accordance with
       the intended methods of disposition by the Selling Shareholders set forth
       in such Registration Statement;

    (c) furnish to each Selling Shareholder such number of conformed copies of
       such Registration Statement and of each such amendment and supplement
       thereto (in each case including all exhibits and documents incorporated
       by reference, appropriately legended in the case of those exhibits filed
       on a confidential basis), and, so long as Parent is required to keep such
       Registration Statement effective pursuant to paragraph (b) above, such
       number of copies of the prospectus contained in such Registration
       Statement (including each preliminary prospectus and any summary
       prospectus) and any other prospectus filed pursuant to the applicable
       Securities Laws, in conformity with the requirements of the applicable
       Securities Laws, and such other documents, as such Selling Shareholder
       may reasonably request;

    (d) use its best efforts (x) to register or qualify all Registrable
       Securities offered by such Registration Statement under such other state
       or "blue sky" Securities Laws of such jurisdiction where an exemption is
       not available and as any Selling Shareholder shall reasonably request,
       (y) to keep such Registration or qualification in effect for so long as
       such Registration Statement remains in effect and (z) to take any other
       action that may be necessary or advisable to enable such Selling
       Shareholders to consummate the disposition in such jurisdictions of the
       Registrable Securities to be sold by such Selling Shareholders, except
       that Parent shall not for any such purpose be required to: (i) qualify
       generally to do business as a foreign corporation in any jurisdiction
       wherein it would not, but for the requirements of

                                       21
<PAGE>
       this paragraph, be obligated to be so qualified; (ii) become subject to
       taxation in any jurisdiction where it would not then be so subject; or
       (iii) take any action that would subject it to general service of process
       in any such jurisdiction (except to the extent required by the applicable
       laws of a particular jurisdiction in connection with the particular
       offering);

    (e) use its reasonable best efforts to cause all Registrable Securities
       offered by such Registration Statement to be registered with or approved
       by such other federal, provincial or state governmental agencies or
       authorities as may be necessary in the opinion of counsel to Parent and
       counsel to the Selling Shareholders to enable the Selling Shareholders to
       consummate the disposition of such Registrable Securities;

    (f) furnish at the effective date of such Registration Statement and the
       date of closing of the sale of the Registrable Securities (whether or not
       such sale is underwritten), to each Selling Shareholder, and each Selling
       Shareholder's underwriters, if any, a signed counterpart of:

        (i) an opinion of counsel for Parent, dated the effective date of such
            Registration Statement (or such date of closing, as applicable), and

        (ii) a "comfort" letter signed by the independent public accountants who
             have certified Parent's financial statements included or
             incorporated by reference in such Registration Statement,

       covering substantially the same matters with respect to such Registration
       Statement (and the prospectus included therein) and, in the case of the
       accountants' comfort letter, with respect to events subsequent to the
       date of such financial statements, as are customarily covered in opinions
       of issuer's counsel and in accountants' comfort letters delivered to the
       underwriters in underwritten public offerings of securities;

    (g) notify each Selling Shareholder at any time when a prospectus relating
       to the Registration is required to be delivered under the Securities
       Laws, upon discovery that, or upon the happening of any event known to
       Parent as a result of which, the prospectus included in such Registration
       Statement, as then in effect, includes an untrue statement of a material
       fact or omits to state any material fact required to be stated therein or
       necessary to make the statements therein not misleading, in the light of
       the circumstances under which they were made, and promptly prepare and
       furnish to each Selling Shareholder a reasonable number of copies of a
       supplement to or any amendment of such prospectus as may be necessary so
       that, as thereafter delivered to the purchasers of such securities, such
       prospectus shall not include 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 not misleading in the light of the
       circumstances under which they were made;

    (h) otherwise use its reasonable best efforts to comply with all applicable
       rules and regulations of the Securities Laws and, if required, make
       available to its Shareholders, as soon as reasonably practicable, an
       earnings statement covering the period of at least twelve months, but not
       more than eighteen months, beginning with the first full calendar month
       after the effective date of such Registration Statement, which earnings
       statement shall satisfy the provisions of Securities Laws;

    (i) permit any Selling Shareholder to participate in the preparation of such
       Registration Statement and to include therein material, furnished to
       Parent in writing, which in the reasonable judgement of the Selling
       Shareholder should be included and which is reasonably acceptable to
       Parent;

    (j) if any proposed Registration Statement refers to a Selling Shareholder
       by name or otherwise as the holder of any securities of Parent then:
       (i) upon reasonable request Parent shall be

                                       22
<PAGE>
       required to insert therein language, in form and substance reasonably
       satisfactory to such Selling Shareholder, Parent and the lead managing
       underwriter(s), to the effect that the ownership by such Selling
       Shareholder of such securities is not to be construed as a recommendation
       by such Selling Shareholder as to the investment quality of Parent's
       securities offered thereby and that such ownership does not imply that
       such Selling Shareholder will assist in meeting any future financial
       requirements of Parent; or (ii) in the event that such reference to such
       Selling Shareholder by name or otherwise is not required by the
       applicable Securities Laws, any similar federal, provincial or state
       statute, or any rule or regulation of any other regulatory body having
       jurisdiction over the offering, then in force, Parent shall be required
       at the request of such Selling Shareholder to delete the reference to
       such Selling Shareholder;

    (k) provide and cause to be maintained a transfer agent and registrar for
       all Registrable Securities offered by such Registration Statement; and

    (l) use its best efforts to list all Registrable Securities covered by such
       Registration Statement on any securities exchange or trading market on
       which Parent's Registrable Securities are then listed.

    The Shareholders shall not have any right to obtain or seek an injunction
    restraining or otherwise delaying any registration as the result of any
    controversy that might arise with respect to the interpretation or
    implementation of this Section 10.4.

10.5 DEMAND REGISTRATION -- UNDERWRITING AGREEMENT/REPRESENTATIONS AND
     WARRANTIES

    If requested by the underwriters for any underwritten offering of
    Registrable Securities pursuant to a Demand Registration, Parent will use
    all reasonable efforts to enter into an underwriting agreement with such
    underwriters for such Demand Registration, such agreement to be reasonably
    satisfactory in substance and form to Parent, the Selling Shareholders and
    the underwriters and to contain such representations and warranties by
    Parent and such other terms as are customary in agreements of that type,
    including, without limitation, indemnities to the effect and to the extent
    provided in Article 11 hereof. The Selling Shareholders will reasonably
    cooperate with Parent in the negotiation of the underwriting agreement. Such
    Selling Shareholders shall be parties to such underwriting agreement. All of
    the representations and warranties by, and the other agreements on the part
    of, Parent to and for the benefit of such underwriters shall also be made to
    and for the benefit of such Selling Shareholders and any or all of the
    conditions precedent to the obligations of such underwriters under such
    underwriting agreement shall also be conditions precedent to the obligations
    of such Selling Shareholders. No Selling Shareholder shall be required to
    make any representations or warranties to or agreements with Parent other
    than representations, warranties or agreements regarding such Selling
    Shareholder, matters pertaining to the Selling Shareholder's contractual or
    other arrangements with Parent, such Selling Shareholder's Registrable
    Securities and such Selling Shareholder's intended method of distribution or
    any other representations required by the applicable Securities Laws.

10.6  PIGGYBACK REGISTRATION -- UNDERWRITING AGREEMENT/REPRESENTATIONS AND
     WARRANTIES

    If requested by the underwriters for any underwritten offering of
    Registrable Securities pursuant to a Piggyback Registration, the Selling
    Shareholders shall be parties to the underwriting agreement between Parent
    and such underwriters. All of the representations and warranties by, and the
    other agreements on the part of, Parent to and for the benefit of such
    underwriters shall also be made to and for the benefit of the Selling
    Shareholders, and any or all of the conditions precedent to the obligations
    of such underwriters under such underwriting agreement shall also be
    conditions precedent to the obligations of the Selling Shareholders. No
    Selling Shareholder shall be required

                                       23
<PAGE>
    to make any representations and warranties to, or agreements with, Parent or
    such underwriters other than those representations, warranties or agreements
    regarding the Selling Shareholder, matters pertaining to the Selling
    Shareholder's contractual or other arrangements with Parent, the Selling
    Shareholder's Securities, the Selling Shareholder's intended method of
    distribution and any other representations required by the applicable
    Securities Laws.

10.7  ABILITY OF SELLING SHAREHOLDER TO PARTICIPATE IN DUE DILIGENCE

    In connection with the preparation and filing of each Registration Statement
    under the Securities Laws, Parent will give the Selling Shareholders,
    provided such Selling Shareholder is not a Tantau Shareholder, their
    underwriters, if any, and their respective counsel the opportunity to
    participate in the preparation of such Registration Statement, each
    prospectus included therein or filed with the Securities Regulators, and
    each amendment thereof or supplement thereto, and will give each of them
    such reasonable access to the books and records of Parent and such
    opportunities to discuss the business of Parent with its officers and the
    independent public accountants who have certified its financial statements
    as shall be necessary, in the opinion of such holders, and such underwriters
    and their respective counsel, to conduct a reasonable investigation. Parent
    shall promptly notify such holders and their counsel of any stop order
    issued or threatened by the Securities Regulators and take all reasonable
    actions required to prevent the entry of such stop order or to remove it if
    entered.

10.8  CONTINUOUS DISCLOSURE OBLIGATIONS OF PARENT

    If Parent becomes subject to the reporting requirements of a jurisdiction
    where the Registrable Securities become qualified, Parent will use its best
    efforts to file with the applicable Securities Regulators such information
    as the applicable Securities Regulators may require in a timely fashion; and
    in such event, Parent shall use its best efforts to take all action as may
    be required in order to maintain the Registration of such Registrable
    Securities in good standing and not in default. Parent shall furnish to the
    Selling Shareholders forthwith upon request: (i) a written statement by
    Parent as to its compliance with the reporting requirements of applicable
    Securities Regulators; (ii) a copy of the most recent annual or quarterly
    report of Parent as filed with the applicable Securities Regulators; and
    (iii) such other reports and documents as the Selling Shareholders may
    reasonably request in availing themselves of any rule or regulation of the
    Securities Regulators allowing the Selling Shareholders to sell any such
    Registrable Securities without qualifying a prospectus or completing a
    registration.

10.9  RIGHT TO SUSPEND A REGISTRATION RIGHT

    Parent may suspend a Registration Right at any time prior to such
    Registration Statement becoming effective if Parent determines in good faith
    (and, as soon as reasonably practicable, so certifies in writing to such
    Selling Shareholder) that the public disclosure requirements imposed on
    Parent under the applicable Securities Laws in connection with the
    Registration Statement would require disclosure of any activity or
    transaction or preparations or negotiations for any activity or transaction
    (the "Parent Activity") that Parent in good faith desires to keep
    confidential for business reasons, or during which there exists any other
    material non-public information relating to Parent which Parent determines
    in good faith should not be disclosed; provided that: (i) Parent shall use
    commercially reasonable efforts to minimize the length of any such period of
    suspension; and (ii) any such suspension shall be applied in the same manner
    to all other security holders included in such Registration Statements and
    to any other Registration Statement or proposed offering of Parent's
    securities proposed or then in effect.

                                       24
<PAGE>
10.10  SELLING SHAREHOLDER DUTY TO UPDATE

    A Selling Shareholder shall notify Parent, at any time when a prospectus is
    required to be delivered under applicable Securities Laws, of the happening
    of any event as a result of which the prospectus included in the applicable
    Registration Statement, as then in effect, with respect to information
    provided or confirmed by such Shareholder in writing, includes an untrue
    statement of a material fact or omits to state a material fact required to
    be stated therein or necessary to make the statements therein not misleading
    in light of the circumstances then existing. Such Selling Shareholder shall
    immediately upon the occurrence of any such event cease using such
    prospectus. If so requested by Parent, such Selling Shareholder shall
    promptly return to Parent any copies of any prospectus in its possession
    (other than permanent file copies) that contains an untrue statement of a
    material fact or omits to state a material fact required to be stated
    therein or necessary to make the statements therein not misleading in light
    of the circumstances then existing, and shall not sell any Parent Shares
    pursuant to such Registration Statement until it receives from Parent a
    Registration Statement that cures such untrue statement or omission.

10.11  MARKET STAND-OFF

    (a) The Shareholders each hereby agree that, during the period of duration
       specified in writing by the lead managing underwriter(s) of Parent
       Shares, commencing two trading days prior to the establishment of the
       proposed pricing range for the offering and following the effective date
       of a Company Registration filed under applicable Securities Laws, each of
       them shall not, to the extent requested by such underwriter(s), directly
       or indirectly sell, offer to sell, contract to sell (including, without
       limitation, any short sale), grant any option to purchase or otherwise
       transfer or dispose of (other than to donees who agree to be similarly
       bound) any securities of Parent held by it at any time during such period
       except Parent Shares included in such Registration; provided, however,
       that:

        (i) such agreement shall be applicable only to the first of such
            underwritten Company Registrations; and

        (ii) such agreement shall not apply unless Parent and, if requested by
             the underwriter(s), all officers and directors of Parent and all
             other persons with Registration Rights (whether or not pursuant to
             this Agreement) enter into similar agreements;

       (iii) such agreement shall not provide for a market stand-off time period
             which exceeds 90 days from the effectiveness of the Registration
             Statement; and

        (iv) any such agreement shall be substantially in the form of the
             lock-up undertaking delivered by the Strategic Partners at the time
             of Parent's initial public offering.

       Parent shall provide the Shareholders with reasonable notice of when the
       establishment of the proposed pricing range for the offering is expected
       to occur. In order to enforce the foregoing covenant, Parent may impose
       stop-transfer instructions with respect to the Parent Shares of the
       Founding Shareholder and the Strategic Partners and Tantau Shareholders
       until the end of such period.

    (b) Notwithstanding the provisions of Section 10.11(a) hereof, the
       provisions of this Section 10.11 shall apply to a Selling Shareholder
       each time such Selling Shareholder elects to participate in an
       underwritten Registration hereunder and has complied with the
       requirements of Section 10.2(a) hereof.

                                       25
<PAGE>
10.12  ABILITY OF PARENT TO GRANT ADDITIONAL REGISTRATION RIGHTS

    (a) Parent may grant additional ranking or PARI PASSU registration rights
       only with the prior written agreement of the Founding Shareholder and
       each of the Strategic Partners whose Registration Rights have not expired
       or terminated in accordance with the terms of this Agreement, provided
       that such additional registration rights do not affect the Piggyback
       Registration rights of the Tantau Shareholders under Section 6.1 hereof
       in a manner different than the Piggyback Registration rights of the
       Founding Shareholder and of the Strategic Partners under Sections 4.2 and
       5.2 hereof, respectively. If the later proviso is not satisfied, then the
       granting of such additional registration rights shall require the consent
       of the Tantau Shareholders whose Registration Rights have not expired or
       terminated in accordance with the terms of this Agreement and who hold
       more than 50% of the Tantau Qualified Parent Shares held by all such
       Tantau Shareholders.

    (b) Notwithstanding the provisions of Section 10.12(a), Parent may grant
       registration rights PARI PASSU to those granted to the Shareholders under
       this Agreement to its directors and senior management and the directors
       and senior management of its Subsidiaries with the consent of the
       Founding Shareholder and each of the Strategic Partners.

    (c) Notwithstanding the provisions of Section 10.12(a), Parent may, without
       the consent of any of the Shareholders, grant ranking registration rights
       in respect of equity securities issued on a private placement basis to
       securityholders of a company or business acquired by Parent, where the
       contractual right and entitlement to a distribution or registration on
       From F-1 or F-3 (or Form S-1 or S-3, or similar short-form prospectus or
       registration statement), is granted to such equity holders at the time
       and in conjunction with such acquisition. For greater certainty, the
       exercise of such ranking registration rights shall be considered to be a
       Company Registration such that the Shareholders shall be entitled to
       exercise their Piggyback Registration rights under Sections 4.2, 5.2 or
       6.1, as the case may be, in connection therewith.

                                   ARTICLE 11
           INDEMNIFICATION PROVISIONS RELATING TO REGISTRATION RIGHTS

11.1  PARENT INDEMNITY OBLIGATION

    In connection with any Registration, Parent agrees to indemnify, to the full
    extent permitted by law, each Selling Shareholder, each other person or
    entity which participates as an underwriter in the offering or sale of such
    Registrable Securities and each other person or entity which controls such
    Selling Shareholder or any such underwriter, and their respective directors,
    officers, partners, agents and Affiliates, against all losses, claims,
    damages, liabilities and expenses (including legal fees and disbursements on
    a solicitor and client basis) to which such Selling Shareholder or
    underwriter or any such director, officer, partner, agent, Affiliate or
    controlling person or entity may become subject under applicable law or
    otherwise, insofar as such losses, claims, damages or liabilities arise out
    of or are based upon any untrue or alleged untrue statement of a material
    fact contained in any Registration Statement (or any amendment or supplement
    thereto) or any omission or alleged omission to state therein a material
    fact required to be stated therein or necessary to make the statements
    therein, in the light of the circumstances under which they were made, not
    misleading, except insofar as the same are caused by any untrue statement or
    alleged untrue statement or any such omission or alleged omission if
    (i) such untrue statement or omission is completely corrected in an
    amendment or supplement to such Registration Statement prepared in a timely
    fashion by Parent and Parent has furnished such Selling Shareholder (or
    underwriter, if any) with a sufficient number of copies of the same, the
    Selling Shareholder (or underwriter, if any) having an obligation under the
    Securities Laws to deliver a prospectus or prospectus supplement in
    connection with such sale of Registrable Securities thereafter fails to
    deliver such

                                       26
<PAGE>
    prospectus or prospectus supplement as so amended or supplemented prior to
    or concurrently with the sale of Registrable Securities to the person
    asserting such loss, claim, damage or liability, or (ii) such untrue
    statement or omission is caused by or contained in any information with
    respect to any Selling Shareholder which was furnished in writing to Parent
    by the Selling Shareholder expressly for use therein, or caused by the
    Selling Shareholder's failure to deliver (contrary to the requirements of
    the applicable Securities Laws or contrary to an undertaking given by the
    Selling Shareholder) to a prospective purchaser a copy of the Registration
    Statement or any amendment or supplement thereto. Such indemnity shall
    remain in full force and effect regardless of any investigation made by or
    on behalf of such Selling Shareholder or any such director, officer,
    partner, employee, agent, Affiliate or controlling person and shall survive
    the transfer of Registrable Securities by such Selling Shareholder (or
    underwriter, if any).

11.2  SELLING SHAREHOLDER INDEMNITY OBLIGATION

    Each Selling Shareholder agrees to indemnify, to the full extent permitted
    by law, Parent, its directors and officers and each person who controls
    Parent (within the meaning of the Securities Laws) and, in connection with
    an underwritten offering, each underwriter and each person who controls the
    underwriters (within the meaning of the Securities Laws) against any losses,
    claims, damages, liabilities and expenses (including attorneys' fees and
    disbursements) caused by any untrue or alleged untrue statement of a
    material fact contained in any Registration Statement or any omission or
    alleged omission to state therein a material fact required to be stated
    therein or necessary to make the statements therein, in the light of the
    circumstances under which they were made, not misleading, to the extent, but
    only to the extent, that such untrue statement or omission is in conformity
    with and contained in any information with respect to such Selling
    Shareholder so furnished in writing by such Selling Shareholder expressly
    for use therein, provided, however, that (i) such Selling Shareholder shall
    not be liable in any such case to the extent that any such statement or
    omission is completely corrected in the final Registration Statement, in the
    case of a preliminary Registration Statement, or in an amendment or
    supplement to a Registration Statement or Registration Statement supplement
    and (ii) the liability of such Selling Shareholder under this section shall
    be limited to the amount of proceeds received by such Selling Shareholder in
    the offering giving rise to such liability. Such indemnity shall remain in
    full force and effect, regardless of any investigation made by or on behalf
    of Parent or any such director, officer or controlling person and shall
    survive the transfer of Registrable Securities by such Selling Shareholder.

11.3  INDEMNIFICATION -- PROCEDURES

    Any person entitled to indemnification hereunder (the "Indemnified Party")
    agrees to give prompt written notice to the indemnifying party as provided
    at Section 12.11 hereof (the "Indemnifying Party") after the receipt by such
    person of any written notice of the commencement of any action, suit,
    proceeding or investigation or threat thereof made in writing for which such
    person will claim indemnification or contribution pursuant to this Agreement
    (provided, however, that the failure of any Indemnified Party to give such
    notice shall not relieve the Indemnifying Party of its obligations except to
    the extent that the Indemnifying Party is materially prejudiced by such
    failure to give notice) and, unless in the reasonable judgement of such
    Indemnified Party a conflict of interest may exist between such Indemnified
    Party and the Indemnifying Party with respect to such claim, permit the
    Indemnifying Party to assume the defence of such claim with counsel
    reasonably satisfactory to such Indemnified Party. Provided, however, that
    if the Indemnifying Party does not inform the Indemnified Party of its
    decision to defend the claim within five business days after receipt of
    notice of the claim from the Indemnified Party (and as soon as practicable
    thereafter the identity of counsel retained for the defence), or thereafter
    abandons the defence or fails to pursue the defence in good faith, then the
    Indemnified Party (in conjunction with all other Indemnified

                                       27
<PAGE>
    Parties) may retain counsel and conduct the defence of the claim in good
    faith and at the Indemnifying Party's cost and expense. Subject to the
    provisions of the last sentence of this paragraph, in such circumstances the
    Indemnifying Party shall be bound by the results obtained by the Indemnified
    Party (unless and until the Indemnifying Party shall thereafter request to
    participate in the defence of the claim, after which the parties shall
    jointly conduct the defence of the claim). If the Indemnifying Party is not
    entitled to, or elects not to, assume the defence of a claim (or thereafter
    abandons such defence or does not pursue such defence in good faith), it
    will not be obligated to pay the fees and expenses of more than one counsel
    with respect to such claim, unless in the reasonable judgement of any
    Indemnified Party a conflict of interest may exist between such Indemnified
    Party and any other of such Indemnified Parties with respect to such claim,
    in which event the Indemnifying Party shall be obligated to pay the fees and
    expenses of such additional counsel or counsels. The Indemnifying Party will
    not be subject to any liability for any settlement made without its written
    consent, which consent shall not be unreasonably withheld or delayed.

11.4  CONTRIBUTION IN LIEU OF INDEMNITY

    (a) If the indemnification provided for in this Article 11 from an
       Indemnifying Party is unavailable to an Indemnified Party hereunder in
       respect of any losses, claims, damages, liabilities or expenses referred
       to therein, then the Indemnifying Party, in lieu of indemnifying such
       Indemnified Party, shall contribute, subject to the same restrictions and
       limitations applicable to such indemnification to the amount paid or
       payable by such Indemnified Party as a result of such losses, claims,
       damages, liabilities or expenses in such proportion as is appropriate to
       reflect the relative fault of the Indemnifying Party and Indemnified
       Party in connection with the actions which resulted in such losses,
       claims, damages, liabilities or expenses, 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 to
       state a material fact, has been made by, or relates to information
       supplied by, such Indemnifying Party or Indemnified Party, and the
       party's relative intent, knowledge, access to information and opportunity
       to correct or prevent such action.

    (b) The parties hereto agree that it would not be just and equitable if
       contribution pursuant to this Section 11.4 were determined by pro rata
       allocation or by any other method of allocation which does not take into
       account the equitable considerations referred to above. No person guilty
       of fraudulent misrepresentation (as defined in the applicable Securities
       Laws) shall be entitled to contribution from any person who was not
       guilty of such fraudulent misrepresentation.

11.5  TAXES APPLICABLE TO INDEMNIFICATION

    The amount paid or payable by a party as a result of the losses, claims,
    damages, liabilities and expenses referred to above shall be deemed to
    include, subject to the limitations set forth in this Article 11, any legal
    or other fees or expenses reasonably incurred by such party in connection
    with any investigation or proceeding. If an Indemnified Party, acting
    reasonably, determines that any payment in respect of indemnification or
    contribution (the "Payment") made pursuant to this Article 11 is subject to
    taxes payable under the EXCISE TAX ACT (Canada) ("GST") or under any
    provincial or other legislation similar to the EXCISE TAX ACT, or under any
    successor legislation of like or similar effect (collectively, the "ETA"),
    or if any sales or similar tax under any provincial, state or other
    legislation not substantially harmonised with the ETA is applicable to such
    Payment, the amount of the Payment shall be increased by the amount of all
    applicable taxes to the extent necessary to compensate the Indemnified party
    for any net GST or similar tax cost not recoverable as input tax credit or
    similar tax recoveries.

                                       28
<PAGE>
11.6  THIRD PARTY BENEFICIARIES

    The Selling Shareholders shall be deemed to be acting as agent and attorney
    herein for their respective controlling persons or entities, their
    respective underwriters (and persons or entities which control such
    underwriters) and the respective directors, officers, partners, agents and
    Affiliates thereof with respect to the rights of indemnification and
    contribution herein contained.

11.7  SURVIVAL

    The indemnification provisions of this Article 11, shall survive the
    completion of any offering of Registrable Securities in a Registration
    Statement and the termination of this Agreement.

11.8  CONFLICT WITH UNDERWRITING AGREEMENT

    To the extent that the provisions on indemnification and contribution in the
    underwriting agreement entered into in connection with an underwritten
    public offering Registration pursuant to this Agreement, are in conflict
    with this Article 11, the provisions of Article 11 shall prevail. Provided,
    however that the provisions of this Section 11.8 only apply to the relative
    rights of Parent and the Shareholders and shall not affect or amend the
    provisions of the underlying underwriting agreement as they apply to the
    underwriters.

                                   ARTICLE 12
                                 MISCELLANEOUS

12.1 AMENDMENT, MODIFICATION AND WAIVER

    (a) Except as otherwise expressly provided, this Agreement may be amended or
       modified only upon the written consent of the Founding Shareholder and
       all the Strategic Partners, in each case, whose Registration Rights have
       not expired or terminated in accordance with the terms of this Agreement.
       Notwithstanding the foregoing, any amendment that would adversely affect
       the Tantau Shareholders in a manner different than the Founding
       Shareholder and the Strategic Partners shall require the written consent
       of the Tantau Shareholders whose Registration rights have not expired or
       terminated in accordance with the terms of this Agreement and who hold
       more than 50% of the Tantau Qualified Parent Shares held by all such
       Tantau Shareholders.

    (b) Except as otherwise expressly provided herein, the obligations of Parent
       and the rights of the Founding Shareholder and the Strategic Partners,
       under this Agreement may be waived only with the written consent of the
       Founding Shareholder and each Strategic Partner whose Registration Rights
       have not expired or terminated in accordance with the terms of this
       Agreement. Notwithstanding the foregoing, any waiver that would adversely
       affect the Tantau Shareholders in a manner different than the Founding
       Shareholder and the Strategic Partners shall require the written consent
       of the Tantau Shareholders whose Registration Rights have not expired or
       terminated in accordance with the terms of this Agreement and who hold
       more than 50% of the Tantau Qualified Parent Shares held by all such
       Tantau Shareholders.

    (c) The Subject to Section 12.1(d) hereof, the consent of persons who have
       purchased Parent Shares from the Founding Shareholder under
       Section 7.5(a) hereof or from one or more Strategic Partners under
       Section 7.5(b), accompanied by an assignment of Registration Rights
       hereunder, (collectively, the "Assignee Shareholders"), shall not be
       required to: (i) amend this Agreement in accordance with 12.1(a) hereof;
       or (ii) waive the obligations of Parent and the rights of the Founding
       Shareholder and the Strategic Partners in accordance with
       Section 12.1(b) hereof or to otherwise consent to any matter with respect
       to this Agreement. Notwithstanding the foregoing, any amendment,
       modification or waiver, as the case may be,

                                       29
<PAGE>
       that would adversely affect the Assignee Shareholders in a manner
       different than the Founding Shareholder and the Strategic Partners shall
       require written consent of the Assignee Shareholders whose Registration
       Rights have not expired or terminated in accordance with this Agreement
       and who hold more than 50% of the Parent Shares held by all such Assignee
       Shareholders.

    (d) In the event that the Founding Shareholder shall assign Registration
       Rights in accordance with the provisions of this Agreement to an
       Affiliate of Gregory Wolfond, such Affiliate shall be treated in a manner
       similar to the Founding Shareholder and the Strategic Partners for the
       purposes of consents required for amendments, modifications and waivers
       under this Section 12.1. Similarly, in the event that a Strategic Partner
       shall assign Registration Rights in accordance with the provisions of
       this Agreement to an Affiliate of such Strategic Partner, such Affiliate
       shall be treated as a Strategic Partner for purposes of consents required
       for amendments, modifications and waivers under this Section 12.1.
       Provided, however, that the immediately preceding two sentences shall
       apply only so long as the assignee remains an Affiliate of the assignor.

12.2 ASSIGNMENT

    (a) This Agreement will be binding upon, and inure to the benefit of, the
       persons or entities who are permitted, by the terms of this Agreement, to
       be successors, assigns and personal representatives of the respective
       parties hereto.

    (b) If any person shall acquire Parent Shares from the Founding Shareholder
       or a Strategic Partner, in any manner, whether by operation of law or
       otherwise, accompanied by a purported assignment of Registration Rights
       hereunder, such shares shall, subject to the provisions of Section 7.5
       hereof, be held subject to all of the terms of this Agreement, and such
       person shall be entitled to receive the benefits hereof, provided that
       such person agrees in writing to be bound by and to perform all of the
       terms and provisions of this Agreement.

    (c) If any person shall acquire Tantau Qualified Parent Shares from a Tantau
       Shareholder, in any manner, whether by operation of law or otherwise,
       such shares shall cease to be subject to the terms of this Agreement and
       all Registration Rights in respect of such shares shall terminate
       effective on the date of such acquisition. The rights and obligations of
       the Tantau Shareholders, under this Agreement are not assignable (whether
       by operation of law or otherwise).

12.3 TERMINATION

    This Agreement shall terminate upon:

    (a) the written agreement of the Founding Shareholder and each of the
       Strategic Partners whose Registration Rights have not expired or
       terminated in accordance with the terms of this Agreement;

    (b) the written agreement of the Tantau Shareholders whose Registration
       Rights have not expired or terminated in accordance with the terms of
       this Agreement, holding more than 50% of the Tantau Qualified Parent
       Shares; and

    (c) the expiry or termination of all the Shareholders' Registration Rights
       hereunder in accordance with the terms of this Agreement.

                                       30
<PAGE>
12.4 RESOLUTION OF DISPUTES

    (a) The following procedure will be adhered to in all disputes arising under
       this Agreement which the parties cannot resolve informally. An aggrieved
       party shall notify Parent, the Board of Directors of Parent, the
       Strategic Partners, the Founding Shareholder and the Tantau Shareholders
       in writing of the nature of the dispute, with as much detail as possible
       with respect thereto. Parent (on behalf of all of the parties hereto
       other than the aggrieved party), on the one hand, and the aggrieved
       party, on the other, shall each appoint a representative to meet (in
       person or by telephone) within seven days after the date of such written
       notification, to attempt to reach an agreement about the nature of the
       dispute and the corrective action to be taken by the respective parties.
       Similarly, if Parent is the aggrieved party, then it, on the one hand,
       and the particular Shareholder(s) in respect of which it has the dispute,
       on the other hand, shall appoint representatives to meet. If the
       respective representatives are unable to agree on corrective action,
       senior executives of the parties to the dispute having authority to
       resolve the dispute without the further consent of any other person shall
       meet or otherwise act to facilitate an agreement within 14 days of such
       written notification. If such senior executives cannot resolve the
       dispute or agree upon a written plan of corrective action to do so within
       seven days after their initial meeting or other action, or if the
       agreed-upon completion dates in the written plan of corrective action are
       exceeded, either party may request arbitration as provided for below.
       Except as otherwise specifically provided, neither party to the dispute
       shall initiate arbitration unless and until this dispute resolution
       procedure has been employed or waived.

    (b) Either party to the dispute shall submit any dispute arising from or
       relating to this Agreement, including any failure to agree on a matter
       requiring agreement, to arbitration in accordance with the provisions of
       Schedule "12.4" hereto.

    (c) No Shareholder shall have any right to obtain or seek an injunction or
       otherwise delay any Company Registration or Demand Registration as a
       result of any controversy that may arise with respect to the
       interpretation or implementation of this Agreement. Provided, however,
       that the provisions of the immediately preceding sentence shall not
       preclude any Shareholder from claiming damages for breach of the
       provisions of this Agreement, provided that such Shareholder has
       otherwise complied with the provisions of this Section "12.4".

12.5 COSTS OF ENFORCEMENT

    If any party to this Agreement seeks to enforce its rights under this
    Agreement by legal proceedings or otherwise, the non-prevailing party will
    pay all costs and expenses incurred by the prevailing party, including,
    without limitation, all reasonable attorneys' and experts' fees.

12.6 COUNTERPART EXECUTION; FACSIMILE DELIVERY

    This Agreement may be executed in several counterparts and delivered by
    facsimile, each of which shall be an original, but all of which together
    shall constitute one and the same agreement.

12.7 INTERPRETATION

    Words importing the singular number shall include the plural and VICE VERSA
    and words importing the use of any gender shall include all genders. The
    division of this Agreement into paragraphs, subparagraphs, sections,
    subsections, clauses and subclauses are for convenience of reference only
    and shall not affect the construction or interpretation of this Agreement.
    Expressions such as "hereof", "herein", "hereto", "hereunder", "hereby" and
    similar expressions shall be construed as referring to this Agreement in its
    entirety and not only to the particular paragraph, subparagraph, section,
    subsection, clause or subclause in which such words appear. Time is of the
    essence.

12.8 ENTIRE AGREEMENT

    This Agreement and the exhibits hereto contains the entire understanding of
    the parties in respect of the subject matter hereof, and supersede all prior
    negotiations and understandings between the parties with respect to such
    subject matter.

12.9 FURTHER ASSURANCES

    Shareholder agrees to execute and deliver, before or after the Effective
    Time (as such term is defined in the Merger Agreement), any additional
    documents reasonably necessary or desirable to carry out the purposes and
    intent of this Agreement.

12.10  GOVERNING LAW

    This Agreement shall be governed by and construed in accordance with the
    laws of the Province of Ontario and the federal laws of Canada applicable
    therein (excluding any conflict of laws rule or principles that might refer

    in all respects, as an Ontario contract. Subject to the provisions of
    Section 12.4 hereof, the parties hereto agree to submit to the exclusive
    jurisdiction of the courts of the Province of Ontario. In any such dispute,
    subject to the provisions of Section 12.4 hereof, the parties shall act
    reasonably and in good faith with a view to having such dispute heard by a
    judge of the Commercial List of the Ontario Superior Court of Justice. EACH
    OF THE PARTIES IRREVOCABLY WAIVES THE RIGHT TO A JURY TRIAL IN CONNECTION
    WITH ANY LEGAL PROCEEDING RELATING TO THIS AGREEMENT OR THE ENFORCEMENT OF
    ANY PROVISION OF THIS AGREEMENT.

    following the resumption of normal mail service, provided that during the
    period that regular mail service shall be interrupted, all Notices shall be
    given by personal delivery or by facsimile transmission.

    Notwithstanding anything to the contrary contained in this Agreement, any
    notice to be given by one or more members of the Founding Shareholder to the
    other Shareholders or Parent shall be deemed to be properly given and
    binding if the Notice is given on behalf of the members of the Founding
    Shareholder by a duly appointed representative of the Founding Shareholder.

12.12  SEVERABILITY

    If any provision of this Agreement is held to be unenforceable for any
    reason, such provision and all other related provisions shall be modified
    rather than voided, if possible, in order to achieve the intent of the
    parties to this Agreement to the extent possible. In any event, all other
    unrelated provisions of this Agreement shall be deemed valid and enforceable
    to the full extent.

12.13  SPECIFIC PERFORMANCE; INJUNCTIVE RELIEF

    The parties hereto acknowledge that Parent will be irreparably harmed and
    that there will be no adequate remedy at law for a violation of any of the
    covenants or agreements of Shareholder set forth herein. Therefore, it is
    agreed that, in addition to any other remedies that maybe available to
    Parent upon any such violation, Parent shall have the right to enforce such
    covenants and agreements by specific performance, injunctive relief or by
    any other means available to Parent at law or in equity and the Shareholder
    hereby waives any and all defenses which could exist in its favor in
    connection with such enforcement and waives any requirement for the security
    or posting of any bond in connection with such enforcement.

                                SCHEDULE "12.4"
                             ARBITRATION PROCEDURES

1.1 DISPUTES COVERED BY THESE RULES

    The disputes to be covered by the provisions of these rules of procedures
    (the "Rules") are those disputes referred to in Section 12.4 of the
    Agreement to which this Schedule 12.4 is attached and which arise out of or
    relate to or are in connection with any of the formation, interpretation,
    application, operation, and enforcement of the Agreement.

1.2 EXCLUSIVE JURISDICTION

    Subject to the provisions of Section 12.10 (Governing Law) of the Agreement,
    it shall be a condition precedent to the bringing of any legal proceedings
    with respect to any dispute arising out of, or relating to, or in connection
    with, any of the formation, interpretation, application, operation and
    enforcement of the Agreement and provided that the settlement procedures set
    forth in Section 12.4 of the Agreement has been pursued, that the settlement
    procedure provided for in these Rules shall have been followed and
    completed.

1.3 APPOINTMENT OF ARBITRATION BOARD

    (a) If any party to the Agreement (a "Party") wishes to have any matter
       under this Agreement arbitrated in accordance with the provisions of this
       Agreement, it shall give notice ("Arbitration Notice") to the other
       Parties specifying particulars of the matter or matters in dispute and
       proposing the name of its nominee.

    (b) Arbitration shall be carried out by an Arbitration Board of three
       persons. If the Parties agree in writing, the Arbitration Board may be
       composed of a single arbitrator.

    (c) Each side to the dispute being arbitrated in accordance with these
       procedures, shall select an independent arbitrator as selected in
       accordance with paragraph (d), and then the two arbitrators shall select
       a third independent arbitrator. If the two arbitrators cannot agree to a
       mutually acceptable third independent arbitrator, who is willing to act,
       within 15 days of the giving of the Arbitration Notice, either Party may
       request an Ontario court of competent jurisdiction to do so. Any Party
       may request that such court, before making such appointment, consult with
       the President of the Computer Law Association as to the identity of
       suitable nominees as Arbitration Board.

    (d) No member of the Arbitration Board may be a director, officer, an
       employee or shareholder of any Party or of any affiliate or associate of
       such Party or any associate of any such director, officer, employee or
       shareholder or any other person who has a direct financial interest in
       such Party or in any associate or affiliate of such Party or of a
       director, officer, employee, or shareholder of such Party or who has a
       direct financial interest in the matter in dispute. The terms "associate"
       and "affiliate" shall have the respective meanings ascribed to such terms
       by the BUSINESS CORPORATIONS ACT (Ontario) on the date hereof.

    (e) Subject to Section 1.8 of this Schedule 12.4, the expenses of the
       Arbitration Board shall be borne equally by the Parties.

1.4 QUALIFICATIONS OF ARBITRATION BOARD.

    The Arbitration Board shall consist of three individuals, one of which shall
    have not less than 10 years experience as a licensed practising corporate or
    securities lawyer, and one of which shall have not less than 10 years
    experience in or with investment or merchant banking for the computer
    software industry. If the Arbitration Board consists of only one person, as
    agreed by the

                                       35
<PAGE>
    Parties, then the sole arbitrator shall have not less than 10 years
    experience in or with corporate or securities law with significant exposure
    to the computer software industry during the previous 5 years and must have
    acted as an arbitrator or mediator within the previous 5 years. Without
    limiting the generality of the foregoing, the Arbitration Board shall be at
    arm's length from both Parties and no member of the Arbitration Board shall
    be a member of the audit or legal firm or firms who advise either Party, nor
    shall he/she be a person who is otherwise regularly retained by such
    Parties.

1.5 SUBMISSION OF WRITTEN STATEMENTS

    (a) Within 20 days of the appointment of the Arbitration Board, the Party
       initiating the arbitration (the "Claimant") shall send the other Parties
       (collectively, the "Respondent") a Statement of Claim setting out in
       sufficient detail the facts and any contentions of law on which it
       relies, and the relief that it claims.

    (b) Within 20 days of the receipt of the Statement of Claim, the Respondent
       shall send the Claimant a Statement of Defence stating in sufficient
       detail which of the facts and contentions of law in the Statement of
       Claim it admits or denies, on what grounds, and on what other facts and
       contentions of law he relies.

    (c) Within 20 days of receipt of the Statement of Defence, the Claimant may
       send the Respondent a Statement of Reply.

    (d) All Statements of Claim, Defence and Reply shall be accompanied by
       copies (or, if they are especially voluminous, lists) of all essential
       documents on which the Party concerned relies and which have not
       previously been submitted by any Party, and (where practicable) by any
       relevant samples.

    (e) After submission of all the Statements, the Arbitration Board will give
       directions for the further conduct of the arbitration.

1.6 MEETINGS AND HEARINGS

    (a) The arbitration shall take place in the City of Toronto, Ontario or in
       such other place as the Claimant and the Respondent shall agree upon in
       writing. The arbitration shall be conducted in English unless otherwise
       agreed by such Parties and the Arbitration Board. Subject to any
       adjournments which the Arbitration Board allows, the final hearing will
       be continued on successive working days until it is concluded.

    (b) All meetings and hearings will be in private unless the Parties
       otherwise agree.

    (c) Any Party may be represented at any meetings or hearings by legal
       counsel.

    (d) Each Party may examine, cross-examine and re-examine all witnesses at
       the arbitration.

1.7 POWERS OF ARBITRATOR

    By submitting a dispute to settlement under these Rules, the Parties shall
    be taken to have conferred on the Arbitration Board the following
    jurisdiction and powers, to be exercised by the Arbitration Board so far as
    the relevant law allows, and in its absolute and unfettered discretion, if
    the Arbitration Board shall judge it to be expedient for the purpose of
    ensuring the just, expeditious, economical and final determination of the
    dispute. The Arbitration Board shall have jurisdiction to:

    (a) determine any question of fact and law;

    (b) determine any question as to its own jurisdiction;

                                       36
<PAGE>
    (c) determine any question of good faith, dishonesty or fraud arising in the
       dispute;

    (d) order any Party to furnish such further details of the Party's case, in
       fact or in law, as it may require;

    (e) proceed notwithstanding the failure or refusal of any Party to comply
       with these Rules or with its orders or directions, or to attend any
       meeting or hearing, but only after giving that Party written notice that
       it intends to do so;

    (f) order the Parties to produce to the Arbitration Board, and to each other
       for inspection, and to supply copies of, any documents in their
       possession or power which it determines to be relevant. Notwithstanding
       the foregoing, the Arbitration Board shall allow discovery only to the
       extent of a single request for production of documents; oral depositions
       or other discovery requests shall not be permitted unless the Arbitration
       Board finds and informs the Parties that denial of such requests would be
       manifestly unjust;

    (g) receive and take into account such written or oral evidence as it shall
       determine to be relevant, whether or not strictly admissible in law;

    (h) hold meetings and hearings (at which the Parties may be represented by
       legal counsel) and consider written and oral evidence and make his/her
       award (including any interim award considered necessary by the
       Arbitration Board, and the final award) in Ontario, and, with the
       concurrence of the Parties thereto, elsewhere; and

    (i) make any other interim or final orders which it considers to be
       appropriate in all the circumstances for any of the above purposes.

    In addition, the Arbitration Board shall have such further jurisdiction and
    powers as may be allowed to it by the INTERNATIONAL COMMERCIAL ARBITRATIONS
    ACT (Ontario), the Agreement, the specific submission referred to herein,
    the Rules of the Institute and the arbitral laws of any place in which it
    holds hearings or in which witnesses attend, and of any place in which it
    gives any directions or makes any orders or any award.

1.8 THE AWARD

    The Arbitration Board shall include in its award an order as to the payment
    of the costs of the proceedings and reasonable counsel fees, and, subject to
    the discretion of the Arbitration Board, costs will follow success unless,
    in the opinion of the Arbitration Board, there is a compelling reason to
    depart from such result. Any Party ordered to pay costs may avail itself of
    any procedure for the taxing of costs, provided, however, that the Parties
    specifically agreed that the officer taxing such costs need not be bound by
    any statutory scale of costs.

    The Arbitration Board will make its decision in writing and, unless the
    Parties otherwise agree, the Arbitration Board's reasons will be set out in
    the award. The Arbitration Board will send such award to the Parties as soon
    as practicable after the conclusion of the proceedings. The award shall be
    final and binding on the Parties and shall not be subject to any appeal or
    review procedure whatsoever, provided that the Arbitration Board followed
    the Rules in good faith. The Arbitration Board shall reconsider its findings
    once at the request and expense of a Party, but in such event shall limit
    the Parties to a single memorandum stating any relevant new evidence, points
    and authorities, unless doing so would be manifestly unjust.

1.9 ACCESS TO COURTS FOR ENFORCEMENT AND INTERIM REMEDIES

    The Parties consent to the award of the Arbitration Board being entered in
    any Court having jurisdiction for the purposes of enforcement. In addition,
    if it appears to any Party that the

                                       37
<PAGE>
    Arbitration Board lacks the power to give effective interim relief, such
    Party may apply to any appropriate Court for such relief.

1.10 CONFIDENTIALITY

    All meetings and hearings of or by the Arbitration Board shall be in
    private. All matters in dispute, all claims, submissions, evidence and
    findings, and the award itself (collectively, the "Information") shall be
    kept confidential by the Arbitration Board, and no information regarding any
    of the foregoing will be released to any third party or otherwise made
    public without the written consent of the Parties, except as otherwise
    contemplated herein and except for such information which is not
    confidential information.
