any provision of this Deed is held to be invalid or unenforceable, then such provision shall (so far as it is invalid or unenforceable) be given no effect and shall be deemed not
to be included in this Deed but without invalidating any of the remaining provisions of this Deed. In such event, the parties shall co-operate and negotiate in good faith to agree
provisions (to replace those which are invalid or unenforceable) which are not invalid or unenforceable, or which can otherwise be put into effect and which, as far as possible, are legally and

Shareholders pursuant to this Agreement, on or before the Shelf Filing Deadline, the Company shall file with the Commission a Shelf Registration Statement relating to the offer and sale of the
Registrable Securities by the Shareholders from time to time in accordance with the methods of distribution elected by such Shareholders and set forth in the Shelf Registration Statement and,
thereafter, shall use its reasonable best efforts to cause such Shelf Registration Statement to be declared effective under the Securities Act by the commencement of the Shelf Period. If, on the Shelf
Filing Deadline, the Company does not qualify to file a Shelf Registration Statement under the Securities Act for any reason other than as a result of any failure by any Shareholder to provide
information required for such qualification, then the provisions of Section 2.2 shall apply; provided,  however, that, if, at any time after the Shelf
Filing Deadline and prior to the expiration of the Shelf Period), the Company does so qualify, it shall,

        (c)    Suspension of Registration.    In the event that, in the reasonable judgment of the Company, it is advisable to
suspend use of a Prospectus included in a Shelf Registration Statement due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company
believes public disclosure would be detrimental to the Company, the Company may, upon giving prompt written notice of such action to all Selling Shareholders, suspend use of the Shelf Registration
Statement (a "Shelf Suspension"); provided, however,
that the Company shall not be permitted to exercise a Shelf Suspension (i) more than two (2) times during the Shelf Period, or (ii) for a period exceeding sixty (60) days
on any one (1) such occasion. In the case of a Shelf Suspension, the Selling Shareholders agree to suspend use of the applicable Prospectus in connection with any sale or purchase of, or offer
to sell or purchase, Registrable Securities, upon receipt of the notice referred to above. The Company shall promptly (but in all events within three (3) Business Days) notify the Selling
Shareholders upon the termination of any Shelf Suspension, amend or supplement the Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Selling
Shareholders such numbers of copies of the Prospectus as so amended or supplemented as the Selling Shareholders may reasonably request. The Company agrees, if necessary, to supplement or make
amendments to the Shelf Registration Statement, if required by the Registration form used by the Company for the Shelf Registration or by the instructions applicable to such Registration form or by
the Securities Act or the rules or regulations promulgated thereunder. 

        (d)    Unavailability of Shelf Registration.    If, on or at any time during the Shelf Period, the Shelf Registration
Statement is not effective under the Securities Act or is not available for use by the Shareholders for a period exceeding 30 days (except in the case of a Shelf Suspension), then at any time
thereafter the provisions of Section 2.2 shall apply. 

        (e)    Underwritten Offering; Selection of Managing Underwriter.    If the holders of not less than a majority of the
Registrable Securities included in any offering pursuant to such Shelf Registration Statement so elect, such offering of Registrable Securities shall be in the form of an Underwritten Offering, and
the Company shall amend or supplement the Shelf Registration Statement for such purpose. The holders of a majority of such Registrable Securities included in such Underwritten Offering shall have the
right to select the managing underwriter or underwriters to administer such offering; provided that such managing underwriter or underwriters shall be
reasonably acceptable to the Company.

	2.2
	Demand Registration. 

        (a)    Demand by Shareholders.    Subject to Section 2.2(e), at (i) any time from the date of expiration
of the Shelf Period until the fifth (5th) anniversary of the date hereof and (ii) any time during the Shelf Period if the Shelf Registration Statement is not effective under the
Securities Act or is not available for use by the Shareholders for a period exceeding thirty (30) days other than for the reasons set forth in Section 2.1(c), holders (the
"Initiating Holders") of not less than fifty percent (50%) of the Registrable Securities then outstanding may request, in writing, that the Company
effect a Registration of Registrable Securities on a Registration Statement on Form F-1 (or any successor form) or Form F-3 (or any successor form), as selected
by the Company (a "Demand Registration Statement"); provided that such Registrable Securities have an aggregate value of at least $10,000,000 (based on
the then current public market price). Subject to the receipt by the Company of any information or documents required to be provided by Initiating Shareholders pursuant to this Agreement, the Company
shall (i) file a Demand Registration Statement within forty-five (45) days of a request for a Demand Registration, (ii) use its reasonable best efforts to cause
such Demand Registration Statement to promptly be declared effective under the Securities Act and the "Blue Sky" laws of such jurisdictions as any holder of Registrable Securities being registered
under such Registration or any underwriter, if any, reasonably requests and (iii) cause such Demand Registration Statement to remain effective for such period of up to ninety (90) days
as requested by the Initiating Holders. 

        (b)    Demand Notice.    Upon receipt of any request for a Demand Registration, the Company shall, within ten
(10) days of receipt of such request, give written notice of such proposed Registration to all other Shareholders. Such Shareholders shall have the right, by giving written notice to the
Company within ten (10) days after the Company provides its notice, to elect to have included in such Registration those Registrable Securities as such Shareholders may request in such notice
of election, subject in the case of an Underwritten Offering to the approval of the managing underwriter or underwriters (as selected pursuant to Section 2.2(c)). Thereupon, the Company shall
use its reasonable best efforts to effect the Registration as soon as practicable of all Registrable Securities which the Company has been requested to so Register. 

        (c)    Underwritten Offering; Selection of Managing Underwriter.    If the Initiating Holders of a Demand Registration
so elect, such Demand Registration shall be in the form of an Underwritten Offering. The Initiating Holders of such Underwritten Offering shall have the right to select the managing underwriter to
administer such offering from among a group of five (5) potential underwriters (which shall include Credit Suisse First Boston Corporation or its successor) identified by the Company and, if it
is appropriate in the reasonable judgment of the Initiating Holders that a co-managing underwriter be named, the Company shall have the right to select such co-managing
underwriter; provided that such selections shall be reasonably acceptable to the Company and the Initiating Holders. 

I-5

 

        (d)    Priority of Securities Registered Pursuant to Demand Registrations.    Notwithstanding any other provision of
this Section 2.2, if the managing underwriter or underwriters of a proposed Underwritten Offering of the Registrable Securities included in a Demand Registration determines (or, in the case of
a Demand Registration not being underwritten, the Initiating Holders determine) that the inclusion of all Registrable Securities requested by Shareholders to be registered would adversely affect on
the offering, the Initiating Holders may limit (in the manner set forth in the following sentence) the number of Registrable Securities to be included in such Registration. The Initiating Holders
shall advise all Shareholders requesting participation in the Demand Registration of such limitation, and the securities to be included in the Registration shall be allocated  pro rata among the
Shareholders that have requested to participate in such Demand Registration on the basis of the relative number of Registrable
Securities then held by each such Shareholder, to the extent necessary to reduce the total number of Registrable Securities to be included in such offering to the number recommended by the managing
underwriter or underwriters, or the Initiating Holders, as the case may be (and, if any such allocations exceed that which a Shareholder has requested, the excess may reallocated in a similar manner,
as reasonably determined by the Initiating Holders). The Company shall not permit any Other Holders to participate in any Demand Registration hereunder without the prior written consent of the
Initiating Holders. 

        (e)    Limitation on Demand Registrations; Demand Withdrawal.    If, as of the date the Shelf Period expires, the
Initial Shareholders and their Affiliates that are Shareholders hold twenty percent (20%) or more of the Registrable Securities outstanding as of the date hereof, the Company shall not be required to
effect more than two (2) Demand Registrations after the Shelf Period; and, if, as of the date the Shelf Period expires, the Initial Shareholders and their Affiliates that are Shareholders hold
less than twenty percent (20%) of the Registrable Securities outstanding as of the date hereof, the Company shall not be required to effect more than one (1) Demand Registration after the Shelf
Period. In addition, if the Company initiates a Registration under Section 2.3, Shareholders shall not be entitled to request a Demand Registration under this Section 2.2 until the
expiration of a period of ninety (90) days following the consummation of the offering pursuant to such Registration. For purposes of this Section 2.2(e), a Registration Statement shall
not be counted until such time as such Registration Statement has been declared effective by the Commission (unless the Initiating Holders withdraw their request for such Registration (other than as a
result of material information concerning the business or financial condition of the Company which is made known to the Shareholders after the date on which such Registration was requested) and elect
not to pay the Registration Expenses therefor pursuant to Section 2.7). 

I-6

 

        (f)    Delay in Filing; Suspension of Registration.    If the filing, initial effectiveness or continued use of a
Demand Registration Statement at any time would require the Company to disclose any pending material developments or other events that have not yet been publicly disclosed and as to which the Company
believes public disclosure would be detrimental to the Company, the Company may, upon giving prompt written notice of such action to the Selling Shareholders, delay the filing or initial effectiveness
of, or suspend the use of the Demand Registration Statement (each, a "Demand Suspension"); provided,  however,
 that the Company shall not be permitted to exercise a Demand Suspension (i) more than two (2) times during any
12-month period, or (ii) for a period exceeding sixty (60) days on any one (1) such occasion. In the case of a Demand Suspension, the Selling Shareholders agree to
suspend use of the applicable Prospectus in connection with any sale or purchase of, or offer to sell or purchase, Registrable Securities, upon receipt of the notice referred to above. The Company
shall promptly (but in all events within three (3) Business Days) notify the Selling Shareholders upon the termination of any Demand Suspension, amend or supplement the Prospectus, if
necessary, so it does not contain any untrue statement or omission and furnish to the Selling Shareholders such numbers of copies of the Prospectus as so amended or supplemented as the Selling
Shareholders may reasonably request. The Company agrees, if necessary, to supplement or make amendments to the Demand Registration Statement, if required by the registration form used by the Company
for the Demand Registration or by the instructions applicable to such registration form or by the Securities Act or the rules or regulations promulgated thereunder or as may reasonably be requested by
the holders of a majority of the Registrable Securities then outstanding. 

        (g)    Limitation on Demand Registration Following Company Offering.    Notwithstanding anything to the contrary in
this Section 2.2, the Company shall not be required to effect any Demand Registration within ninety (90) days following the consummation of any sale of equity securities by the Company
in an Underwritten Offering. 

	2.3
	Incidental Registration. 

        (a)    Participation.    Whenever the Company proposes to file a Registration Statement (other than a
Registration Statement (i) filed pursuant to Section 2.1 or Section 2.2 or (ii) relating either to the sale of securities to employees of the Company pursuant to a share
option, share purchase or similar plan or a Securities Act Rule 145 transaction) at any time and from time to time, it will, no less than twenty (20) days prior to such filing, give
written notice to all Shareholders of its intention to do so. Upon the written request of a Shareholder or Shareholders given within ten (10) days after the Company provides such notice (which
request shall state the intended method of disposition of such Registrable Securities), the Company shall permit not less than twenty percent (20%) (unless Shareholders request in the aggregate a
lesser amount) of the aggregate value of all securities to be registered in such Registration to be Registrable Securities of Shareholders that request the registration thereof and shall use its
commercially reasonable efforts to cause all Registrable Securities of Shareholders that request the registration thereof, in each case so as to permit the sale or other disposition of such
Registrable Securities in accordance with the intended methods of distribution specified in the request of such Shareholder or Shareholders (such a Registration, an "Incidental
Registration"); provided that the Company shall have the right to postpone or withdraw any Registration effected pursuant to
this Section 2.3 without obligation to any Shareholder but the Company shall remain liable for all expenses incurred in connection with the postponed or withdrawn Registration. Each Shareholder
shall be permitted to withdraw all or part of such holder's Registrable Securities from an Incidental Registration at any time prior to the effective date thereof. 

I-7

  

        (b)    Underwritten Offerings.    If the registration for which the Company gives notice pursuant to
Section 2.3(a) is an Underwritten Offering, the Company shall so advise the Shareholders as a part of the written notice given pursuant to Section 2.3(a). In such event, the right of any
Shareholder to include its Registrable Securities in such Registration pursuant to Section 2.3(a) shall be conditional upon such Shareholder's participation in such underwriting on the terms
set forth herein. All Shareholders proposing to distribute Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or
underwriters thereof; provided, that such underwriting agreement shall not provide for indemnification or contribution obligations on the part of the
participating Shareholders that are materially greater than the obligations of the Shareholders pursuant to Section 2.8 hereof. 

        (c)    Priority of Securities Registered Pursuant to Incidental Registrations.    Notwithstanding any other provision
of this Section 2.3, if the managing underwriter or underwriters (or, in the case of a Demand Registration that is not an Underwritten Offering, the Company) determines that the inclusion of
all Registrable Securities requested by Shareholders to be registered would adversely affect the offering, the Company may limit (in the manner set forth in the following sentence) the number of
Registrable Securities to be included in such Registration. The Company shall advise all Shareholders requesting participation in the Incidental Registration of such limitation, and the securities to
be included in the Registration shall be allocated with the following priorities: (i) first, securities to be offered by the Company; (ii) second, with respect to all such Shareholders
and Other Shareholders, in proportion to relative values of the securities that each such holder has requested be so registered (and, if any such allocations exceed that which a Shareholder has
requested, the excess may reallocated in a similar manner, as reasonably determined by the Company); provided,  however, that, in all events, the Company
shall, as provided pursuant to Section 2.3(a), permit not less than twenty percent (20%) (unless
Shareholders request in the aggregate a lesser amount) of the aggregate value of all securities to be registered in such Registration to be Registrable Securities of Shareholders that request the
registration thereof. Each Shareholder shall be permitted to withdraw all or part of such holder's Registrable Securities from an Incidental Registration at any time prior to the effective date
thereof. 

	2.4
	Market Black-out Periods

        (a)    Market Black-out Periods for Shareholders.    Until such time as the Registrable Securities held by
any Shareholder or by any Affiliated Group of Shareholders represents five percent (5%) or less of the outstanding Voting Securities of the Company, such Shareholder or Affiliated Group of
Shareholders will, in the event the Company proposed to sell its equity securities in an Underwritten Offering, if requested by the managing underwriter or underwriters in such Underwritten Offering,
agree not to effect any public sale or distribution of any securities (except, in each case, as part of the such Underwritten Offering, to the extent permitted as an Incidental Registration) that are
the same as or similar to those being registered in connection with such sale by the Company, or any securities convertible into or exchangeable or exercisable for such securities, during the period
beginning seven (7) days before, and ending 90 days (or such lesser period as may be permitted by the Company or such managing underwriter or underwriters) after, the effective date of
the Registration Statement filed in connection with such Registration. 

I-8

 

        (b)    Market Black-out Periods for the Company and Others.    In the case of a Registration of
Registrable Securities pursuant to Section 2.1 or Section 2.2 for an Underwritten Offering, the Company agrees, if requested by the holders of a majority of Registrable Securities to be
included in such Registration or the managing underwriter or underwriters, not to effect any public sale or distribution of any securities that are the same as or similar to those being registered, or
any securities convertible into or exchangeable or exercisable for such securities, during the period beginning seven (7) days before, and ending 90 days (or such lesser period as may be
permitted by such Shareholder or such managing underwriter or underwriters) after, the effective date of the Registration Statement filed in connection with such Registration (or, in the case of an
offering under a Shelf Registration Statement, the date of the closing under the underwriting agreement in connection therewith), to the extent timely notified in writing by a holder of Registrable
Securities covered by such Registration Statement or the managing underwriter or underwriters. Notwithstanding the foregoing, the Company may effect a public sale or distribution of securities of the
type described above and during the periods described above if such sale or distribution is made pursuant to Registrations on Form F-4 (or any successor thereto) or
Form S-8 (or any successor thereto). The Company agrees to use its reasonable best efforts to obtain from each holder of one percent (1%) or more of the outstanding equity
securities of the Company an agreement not to effect any public sale or distribution of any restricted securities of the Company that are the same as or similar to the Registrable Securities being
registered, or any restricted securities convertible into or exchangeable or exercisable for any of such securities, during any such period referred to in this paragraph, except as part of any such
Registration, if permitted. Without limiting the foregoing (but subject to Section 2.6), if after the date hereof the Company grants any Person (other than a Shareholder) any rights to demand
or participate in a Registration, the Company agrees that the agreement with respect thereto shall include such Person's agreement to comply with any blackout period required by this Section as if it
were the Company hereunder. 

	2.5

	2.8
	Indemnification and Contribution. 

I-13

 

        (a)  In
the event of any Registration of any of the Registrable Securities under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless
each Selling Shareholder, each underwriter of such Registrable Securities, and each other person, if any, who controls such Selling Shareholder or underwriter within the meaning of the Securities Act
or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such Selling Shareholder, underwriter or controlling person may become subject under the Securities
Act, the Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in any Registration Statement under which such Registrable Securities were registered under the Securities Act, any preliminary
prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arise out of or are based upon the omission or alleged
omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and the Company will reimburse such Selling Shareholder, underwriter and
each such controlling person for any legal or any other expenses reasonably incurred by such Selling Shareholder, underwriter or controlling person in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in such Registration Statement, preliminary Prospectus
or Prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by or on behalf of such Selling Shareholder, underwriter
or controlling person specifically for use in the preparation thereof provided further, that the Company shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary
Prospectus if the Prospectus would have completely corrected such untrue statement or omission; and provided further, that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged
omission in the Prospectus, if such untrue statement or alleged untrue statement, omission or alleged omission is completely corrected in an amendment or supplement to the Prospectus and if, having
previously been furnished by or on behalf of the Company with copies of the Prospectus as so amended or supplemented, such Selling Shareholder thereafter fails to deliver such Prospectus as so amended
or supplemented prior to or concurrently with the sale of Registrable Securities to the party asserting such loss, claim, damage, liability or expense who purchased such Registrable Securities from
such Selling Shareholder. 

I-14

 

        (b)  In
the event of any Registration of any of the Registrable Securities under the Securities Act pursuant to this Agreement, each Selling Shareholder, severally and not
jointly, will indemnify and hold harmless the Company, each of its directors and each underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning
of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Company, such directors, underwriters or controlling persons may become
subject under the Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Securities were registered under the Securities
Act, any preliminary Prospectus or final Prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any
omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if the statement or omission was made in reliance upon
and in conformity with information relating to such Selling Shareholder furnished in writing to the Company by or on behalf of such Selling Shareholder specifically for use in connection with the
preparation of such Registration Statement, Prospectus, amendment or supplement; provided, however, that
the obligations of a Selling Shareholder hereunder shall be limited to an amount equal to the net proceeds to such Selling Shareholder of Registrable Securities sold in connection with such
Registration. 

        (c)  Each
party entitled to indemnification under this Section 2.8 (the "Indemnified Party") shall give notice to the
party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which
indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom;  provided, that counsel for the Indemnifying Party, who
shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party
(whose approval shall not be unreasonably withheld); and, provided, further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2.8 except to the extent that the Indemnifying Party is
adversely affected by such failure. The Indemnified Party may participate in such defense at such party's expense; provided,  however, that the Indemnifying
Party shall pay such expense if representation of such Indemnified Party by the counsel retained by the Indemnifying
Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding;  provided further that in no
event shall the Indemnifying Party be required to pay the expenses of more than one law firm per jurisdiction as counsel for
the Indemnified Party. The Indemnifying Party also shall be responsible for the expenses of such defense if the Indemnifying Party does not elect to assume such defense. No Indemnifying Party, in the
defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall
consent to entry of any judgment or settle such claim or litigation without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. 

I-15

 

        (d)  In
order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 2.8 is due in accordance with
its terms but for any reason is held to be unavailable to an Indemnified Party in respect to any losses, claims, damages and liabilities referred to herein, then the Indemnifying Party shall, in lieu
of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities to which such party may be subject
in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Selling Shareholders on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Selling Shareholders shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of material fact related to information supplied by the Company or the Selling Shareholders and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Selling Shareholders agree that it would not be just and equitable if
contribution pursuant to this Section 2.8 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to
above. Notwithstanding the provisions of this paragraph of Section 2.8, (a) in no case shall any one Selling Shareholder be liable or responsible for any amount in excess of the net
proceeds received by such Selling Shareholder from the offering of Registrable Securities and (b) the Company shall be liable and responsible for any amount in excess of such proceeds;  provided,
however, that no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Any party entitled to contribution will, promptly
after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this
Section 2.8, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve such
party from any other obligation it or they may have thereunder or otherwise under this Section 2.8. No party shall be liable for contribution with respect to any action, suit, proceeding or
claim settled without its prior written consent, which consent shall not be unreasonably withheld. 

        2.9    Information by Holder.    Each holder of Registrable Securities agrees that to avail itself of the rights
afforded hereby, such holder shall (i) furnish to the Company such information regarding such holder and the distribution proposed by such holder as the Company may reasonably request in
writing and as shall be required in connection with any Registration, qualification or compliance referred to in this Agreement; (ii) make such representations and warranties and indemnities to
the Company and the underwriters in form, scope and substance as are customarily made by Selling Shareholders in primary underwritten offerings; and (iii) obtain opinions of counsel to such
holder and updates thereof (provided that such opinions shall be at the sole expense of the Company) and addressed to the Company and the underwriter
covering the matters customarily covered in opinions requested in underwritten offerings. 

        2.10    Confidentiality of Notices.    Any Shareholder receiving any written notice from the Company regarding the
Company's plans to file a Registration Statement shall treat such notice confidentially and shall not disclose such information to any person other than as necessary to exercise its rights
under this Agreement. 

        2.11    Rule 144 Requirements.    Upon request of any Shareholder, the Company will furnish a written statement
by the Company as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act and such other reports and documents of the Company as such holder
may reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities without Registration. 

I-16

 

        2.12    Termination.    All of the Company's obligations to register Registrable Securities under Section 2.1,
Section 2.2 or Section 2.3 of this Agreement shall terminate as to any holder of Registrable Securities upon the earlier of (i) the date five (5) years after the date of
this Agreement and (ii) such time as the holder would be permitted under Rule 144 of the Securities Act to sell all of its Registrable Securities in any single three (3) month
period. 

        3.    Transfers of Rights.    This Agreement, and the rights and obligations of each Shareholder hereunder, may be
assigned by such Shareholder to (i) Nortel or any of its Subsidiaries and (ii) to any other Person to which at least ten percent (10%) of the Registrable Securities are transferred by
such Shareholder, and such transferee shall be deemed a "Shareholder" for purposes of this Agreement; provided that the transferee provides written
notice of such assignment to the Company and agrees in writing to be bound hereby. 

I-17

  

	4.
	General. 

        (a)    Severability.    If any term or other provision of this Agreement is invalid, illegal or incapable of being
enforced by any applicable Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not fundamentally changed. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated
hereby be consummated as originally contemplated to the greatest extent possible. 

        (b)    Specific Performance.    In addition to any and all other remedies that may be available at law in the event of
any breach of this Agreement, each Initial Shareholder shall be entitled to specific performance of the agreements and obligations of the Company hereunder and to such other injunctive or other
equitable relief as may be granted by a court of competent jurisdiction. 

        (c)    Governing Law.    This Agreement shall be governed by, and construed in accordance with, the Laws of the State
of New York. This Agreement was negotiated and executed in the State and County of New York. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in a New
York state or federal court sitting in the County of New York, and the parties hereby irrevocably submit to the exclusive jurisdiction of such courts in any such action or proceeding and irrevocably
agree to the laying of venue in such courts and waive the defense of an inconvenient forum to the maintenance of any such Action. 

        (d)    Notices.    All notices, requests, claims, demands and other communications hereunder shall be in writing and
shall be given or made (and shall be deemed to have been duly given or made upon receipt) by delivery in person, by overnight courier service, by cable, by facsimile, by telegram, by telex or by
registered or certified mail (postage prepaid, return receipt requested) to the respective Persons at the following addresses (or at such other address for a party as shall be specified in a notice

        (e)    Complete Agreement.    This Agreement together with the Acquisition Agreement and the other Ancillary

term of this Agreement may be waived with respect to all parties to this Agreement (either generally or in a particular instance and either retroactively or prospectively), with the written consent of
the Company and the holders of a majority of the Registrable Securities held by all of the Shareholders; provided that no such amendment shall unfairly
discriminate against any particular holder of Registrable Securities relative to the other holders thereof. Any action taken under this Section 4(f) shall bind all holders of Registrable
Securities. Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of holders of Registrable Securities whose securities are

different parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an
executed counterpart of a signature page to this Agreement by telecopier shall be as effective as delivery of a manually executed counterpart of this Agreement. 

        (i)    Section Headings.    The headings contained in this Agreement are for reference purposes only and shall not
affect in any way the meaning or interpretation of this Agreement.
