8

(b) Response to Registration Request. Upon receipt of the written notice of the Initiating Holder pursuant to Section 3.1(a), the Corporation shall:

(i) promptly, and in any event, within three Business Days of receipt, give written notice of the proposed Demand Registration to the other Holders to provide the other Holders with the opportunity to participate in such registration with respect to the Registrable Securities held by such other Holders; and

(ii) as soon as practicable, but in any event within 60 days (or 120 days in the case of an Initial Offering) after receipt of the request from the Initiating Holder, file with the applicable Commissions and use its commercially reasonable efforts to effect the registration, qualification or compliance (including, without limitation, filing post-effective amendments, appropriate qualifications under applicable blue sky or other state securities Laws and appropriate compliance with applicable Securities Laws and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or that portion of the Registrable Securities as are specified in the Initiating Holder’s request, together with all or that portion of the Registrable Securities of the other Holders, if joining in that request and as are specified in a written request received by the Corporation within five Business Days after receipt by such other Holders of the written notice from the Corporation referred to in Section 3.1(b)(i).

(c) Limitations on Registration Obligations. The Corporation shall not be required to effect more than two Demand Registrations pursuant to this Section 3.1; provided, for greater certainty, that participating in a registration pursuant to the exercise of piggy-back rights by a Holder shall not constitute a Demand Registration; and provided further, subject to Section 3.2, that a registration shall not constitute a Demand Registration requested under this Section 3.1 unless and until it has become effective and the Initiating Holders are able to register and sell at least 90% of the Registrable Securities requested to be included in such registration. In addition, the Corporation will not be obligated to take any action to effect any registration pursuant to this Section 3.1 if the Corporation furnishes to the Initiating Holder a certificate signed by the Chief Executive Officer of the Corporation stating that (a) in the good faith judgment of the Board of Directors of the Corporation, acting reasonably, any such action to effect a registration in the immediate future would materially interfere with a material bona fide financing, acquisition or other transaction being considered at the time of receipt of the request from the Initiating Holder or would require disclosure ofnon-public information, the premature disclosure of which could materially adversely affect the Corporation or materially interfere with such transaction; or (b) the Corporation is engaged in an issuer bid, self-tender or exchange offer and the proposed registration would cause a violation of applicable Securities Laws (each of (a) and (b), a “Delay Certificate”), then the Corporation’s obligation to file a registration statement under this Section 3.1 may be deferred, and any time periods with respect to filing

9

or effectiveness thereof shall be tolled accordingly, for a period not to exceed 90 days from the date the Corporation would have been required to file such registration statement after its receipt of the written request to file such registration statement from the Initiating Holder, provided that the Corporation may not exercise this deferral right more than once in any consecutive12-month period. The Corporation shall not be required to effect any Demand Registration pursuant to this Section 3.1 (i) if such request is made within 180 days after the Corporation effects the Initial Offering; (ii) if the Corporation delivers notice to the holders of Registrable Securities within 30 days of receipt of such request of the Corporation’s intent to file a registration statement for the Initial Offering within 90 days of such notice; (iii) if such securities become eligible for sale in the U.S. pursuant to Rule 144 under the U.S. Securities Act (“Rule 144”) without the volume ormanner-of-sale restrictions and without the requirement for the Corporation to be in compliance with the current public information requirement under Rule 144(c)(1); or (iv) if such Demand Registration will not cover Registrable Securities having an anticipated aggregate gross offering price of at least US$50,000,000 (before deduction of underwriters’ commissions and expenses).

(d) Underwriting.

(i) If the Initiating Holder intends to dispose of the Registrable Securities for which a Demand Registration has been requested under Section 3.1(a) by means of an underwriting, the Initiating Holder shall so advise the Corporation as part of its request pursuant to Section 3.1(a) and the Corporation will advise the other Holders as part of the notice given pursuant to Section 3.1(b)(i) that the right of the other Holders to registration pursuant to Section 3.1 will be conditioned upon that Holder’s participation in the underwriting arrangements required by this Section 3.1(d), and the inclusion of that Holder’s Registrable Securities in the underwriting to the extent requested will be limited to the extent provided in this Agreement.

(ii) The Holders of a majority of the Registrable Securities included in any Demand Registration (on anAs-Converted Basis) will have the right to select the investment banker(s), underwriter(s), and manager(s) to administer the offering, subject to prior consultation with the Corporation.

(iii) The Corporation (together with the Holders proposing or required to distribute their Registrable Securities through such underwriting) shall enter into an underwriting agreement in customary form with the underwriters selected for that underwriting by the Corporation, acting reasonably, such agreement to be in form and substance satisfactory to the Holders requesting such registration, acting reasonably, and to contain such representations and warranties and indemnity and contribution provisions by the Corporation and such other terms as are customarily contained in agreements of that type. Each Holder shall be a party to such underwriting agreement and may, at its option, require that any or all of the representations and warranties by,

10

and the other agreements on the part of, the Corporation to and for the benefit of such underwriters shall also be made to and for the benefit of each Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of each Holder. No Holder requesting a Demand Registration shall be required to make any representations or warranties to or agreements with the Corporation or the underwriters other than representations, warranties or agreements regarding such Holder and its intended method of distribution and any other representation required by the applicable Securities Laws.

(iv) Notwithstanding any other provision of this Section 3.1, if the underwriters, acting reasonably and in good faith, determine in writing that, in their opinion, the number of securities to be included in a Demand Registration exceeds the number of securities that can be sold in the offering relating to such Demand Registration and that the number of securities proposed to be included in the offering in respect of such Demand Registration would adversely affect the price per security to be sold in such offering in respect of such Demand Registration, the underwriters may exclude some or all of the Registrable Securities from the registration. The Corporation will advise the Holders of Registrable Securities of this exclusion and the number and estimated dollar value of Registrable Securities that may be included in the registration. The underwriting will be allocated (i) first, among the Holders of Registrable Securities, in respect of their Registrable Securities, on a pro rata basis based on the number of Registrable Securities held by all such Holders calculated on anAs-Converted Basis, or in such manner as they otherwise agree, (ii) second, to the Corporation if it elects to participate in such registration, and (iii) third, among any other holders of the securities to be included in such offering, allocated among such holders pro rata based on the number of securities held by all such holders calculated on an as converted basis or in such manner as they may otherwise agree. In no event shall any Registrable Securities be excluded from such underwriting unless all other securities are first excluded.

(v) If each of the Holders has included all of the Registrable Securities which such Holder desires to include in that registration, then the Corporation may include additional securities in the registration for sale for the Corporation’s account on the same terms as the Holders’ Registrable Securities, provided the underwriters advise the Corporation and the Holders in writing that the inclusion does not adversely affect the marketing and the orderly sale of the Holders’ Registrable Securities included in that registration at a price range acceptable to the Holders, acting reasonably. If the Corporation determines to include Registrable Securities to be sold by it in any registration requests pursuant to this Section 3.1, such registration shall be deemed to have been a Piggy-Back Registration under Section 3.3, and not a Demand Registration under this Section 3.1. To facilitate the allocation of Registrable Securities in accordance with the above provisions, the Corporation or the underwriters may round the number of Registrable Securities allocated to any Holder to the nearest appropriate “round number” integral.

11

(vi) If any Holder disapproves of the terms of the underwriting, such Holder may elect to withdraw from the underwriting and registration by written notice to the Corporation and the Initiating Holders. Those Registrable Securities of such withdrawing Holder shall continue to be subject to the terms of this Agreement.

3.2 Short Form Registrations

(a) Request for Registration. If, at any time while the Corporation is eligible to complete a Short Form Registration, the Corporation shall receive from any one or more of the Holders (in this Section 3.2, the “Initiating Holder”) a written request or requests that the Corporation effect a Short Form Registration with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Corporation shall:

(i) promptly, and in any event, within three Business Days of receipt, give written notice of the proposed Short Form Registration to the other Holders offering them the opportunity to participate in such registration with respect to the Registrable Securities held by such other Holders; and

(ii) as soon as practicable, but in any event within 45 days after receipt of the request from the Initiating Holder, file with the applicable Commissions and use its best efforts to effect the registration, qualification or compliance (including, without limitation, filing post-effective amendments, appropriate qualifications under applicable blue sky or other state securities Laws and appropriate compliance with applicable Securities Laws and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or that portion of the Registrable Securities as are specified in the Initiating Holder’s request, together with all or that portion of the Registrable Securities of the other Holders (if any) joining in that request as are specified in a written request received by the Corporation within five Business Days after receipt by the other Holders of the written notice from the Corporation referred to in Section 3.1(b)(i). The Corporation shall use its best efforts to keep such registration effective until the earlier of 120 days from the date of effectiveness or until the Holders have completed the distribution described in such registration statement.

(b) Limitations on Short Form Registration Obligations. The Corporation shall not be required to complete any Short Form Registration pursuant to this Section 3.2:

(i) if the Corporation is not eligible to complete a Short Form Registration pursuant to applicable Securities Laws;

12

(ii) if the Holders propose to sell Registrable Securities pursuant to such Short Form Registration such that the aggregate offering price is less than US$5,000,000;

(iii) if the Corporation furnishes a Delay Certificate to the Holders, in which event the Corporation’s obligation to file a registration statement under this Section 3.2 may be deferred for a period not to exceed 90 days from the date of receipt of the written request to file such registration statement from the Initiating Holder, provided that the Corporation may not exercise this deferral right more than once in any consecutive twelve-month period;

(iv) if the Corporation has, within the twelve-month period preceding the date of such request, already effected two Short Form Registrations for the Holders pursuant to this Section 3.2;

(v) if the request is made within 180 days after the Corporation effects the Initial Offering; or

(vi) if such Registrable Securities may be sold pursuant to Rule 144 without the volume ormanner-of-sale restrictions and without the requirement for the Corporation to be in compliance with the current public information requirement under Rule 144(c)(1).

For greater certainty, a registration shall not constitute a Short Form Registration requested under this Section 3.2 unless and until it has become effective and the Initiating Holders are able to register and sell at least 90% of the Registrable Securities requested to be included in such registration.

(c) Underwritings. If the Initiating Holder intends to distribute the Registrable Securities covered by its request by means of an underwriting, it shall so advise the Corporation as a part of its request made pursuant to Section 3.2(a) and the Corporation shall include such information in the written notice referred to in Section 3.2(a)(i). The provisions of Section 3.1(d) shall be applicable to such request mutatis mutandis.

3.3 Piggy-Back Registrations

(a) Notice of Registration. If at any time or from time to time the Corporation determines to register any of its securities (other than pursuant to a Registration Statement on FormS-8, FormS-4 or FormF-4 or their successors or any other form for a similar limited purpose, or any registration statement covering only securities in exchange for securities or assets of another corporation), either for its own account or the account of a security holder or holders or both (other than pursuant to a Demand Registration requested under Section 3.1 or a Short Form Registration required under Section 3.2) including any Initial Offering, on each occasion the Corporation shall:

(i) promptly, and in any event, within three Business Days of such determination, give written notice of the proposed registration to each of the Holders (each such registration, a “Piggy-Back Registration”), provided such notice must be given no later than 30 days prior to the filing of the registration statement by the Corporation in connection with such registration; and

(ii) include in that registration (and any related qualification or compliance under applicable blue sky Laws or other state securities Laws or other Securities Laws), and use its best efforts to include in any underwriting involved in the registration, all or any portion of the Registrable Securities specified in a written request made by any of the Holders and received by the Corporation within 15 Business Days after receipt by such Holder of the written notice delivered by the Corporation pursuant to Section 3.3(a)(i). Such written request may specify that such Holder wishes to include all or a part of the Holder’s Registrable Securities.

(b) Underwriting.

(i) If the Piggy-Back Registration of which the Corporation gives notice pursuant to Section 3.3(a)(i) is for a registered offering involving an underwriting, the Corporation will so advise each of the Holders as a part of such written notice. In such event, the right of any Holder to registration pursuant to this Section 3.3 will be conditioned upon that Holder’s participation in the underwriting arrangements required by this Section 3.3(b) and the inclusion of that Holder’s Registrable Securities in the underwriting to the extent requested will be limited to the extent provided in this Agreement.

(ii) In any Piggy-Back Registration initiated by the Corporation, the Corporation will have the right to select the investment banker(s), underwriter(s), and manager(s) to administer the offering, subject to the approval of the Holders of a majority of the Registrable Securities included in such registration (on anAs-Converted Basis), which in each case will not be unreasonably withheld.

(iii) The Holders proposing to distribute their securities through such underwriting will (together with the Corporation and the other shareholders distributing their securities through that underwriting) enter into an underwriting agreement in customary form with the underwriters, such agreement to be in form and substance satisfactory to all shareholders requesting such registration, acting reasonably, and to contain such representations and warranties and indemnity and contribution provisions by the Corporation and such other terms as are customarily contained in agreements of that type. Each such shareholder (including the Holders) shall be a party to such underwriting agreement and may, at its option, require that any or all of the representations and warranties by, and the other

14

agreements on the part of, the Corporation to and for the benefit of such underwriters shall also be made to and for the benefit of each such Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of each such Holder. No Holder requesting a registration shall be required to make any representations or warranties to or agreements with the Corporation or the underwriters other than representations, warranties or agreements regarding such Holder and its intended method of distribution and any other representation required by the applicable Securities Laws.

(iv) Notwithstanding any other provision of this Section 3.3, if the underwriters and the Corporation, acting reasonably and in good faith, together determine in writing that, in their opinion, the number of securities to be included in the offering relating to such Piggy-Back Registration exceeds the number of securities that can be sold in such offering and that the number of securities proposed to be included in such offering would adversely affect the price per security to be sold in such offering, the Corporation shall be required to include in the offering only that number of such Registrable Securities that the underwriters and the Corporation determine, acting reasonably and in good faith, will not jeopardize the success of the offering. The Corporation will advise the Holders of Registrable Securities distributing their securities through such underwriting of this exclusion and the number and estimated dollar value of the Holders’ securities that may be included in the registration. The underwriting will be allocated (i) first, to the Corporation (but only if it initiates such offering failing which the priority set forth in Section 3.1(d)(iv) shall apply), (ii) second, among the Holders of Registrable Securities, in respect of their Registrable Securities, on a pro rata basis based on the number of Registrable Securities held by all such Holders calculated on anAs-Converted Basis, or in such manner as they may otherwise agree, and (iii) third, among all other holders of the securities to be included in such offering, allocated among such holders pro rata based on the number of securities held by all such holders calculated on an as converted basis or in such manner as they may otherwise agree; provided in each case that, unless the registration is in respect of the Initial Offering, in no event shall the Registrable Securities owned by the Holders included in such underwriting be reduced below 30% of the total number of securities included in such underwriting. To facilitate the allocation of Registrable Securities in accordance with the above provisions, the Corporation may round the number of Registrable Securities allocated to any Holder to the nearest appropriate “round number” integral.

(v) If a Holder disapproves of the terms of the underwriting, such Holder may elect to withdraw from that underwriting by written notice to the Corporation, the other Holders, the underwriters and the other participating shareholders. Any Registrable Securities of such withdrawing Holder excluded or withdrawn from that underwriting will be withdrawn from registration, and will continue to be subject to the terms of this Agreement.

15

(c) Right to Terminate Registration. The Corporation has the right to terminate or withdraw any registration initiated by it under this Section 3.3 prior to the effectiveness of the registration whether or not any Holder or other shareholder has elected to include securities in that registration. The Corporation shall have no liability to any Holder in respect of such withdrawal other than in respect of the reasonablepro-rata Registration Expenses incurred by any Holder if such Holder has elected to include securities in that registration.

3.4 Transfer of Registration Rights

The rights to cause the Corporation to register securities granted to any Holder under Sections 3.1, 3.2, and 3.3 may (if agreed to by such Holder) be transferred or assigned to a transferee or assignee to whom a Holder transfers or assigns (A) not less than 1,000,000 (subject to adjustments for stock dividends, splits, combinations and similar events) of such Holder’s Registrable Securities (other than a transfer under Rule 144 of the U.S. Securities Act or a registration effected pursuant to this Agreement or any other transfer under which securities will cease to be Registrable Securities), or (B) all or part of such Holder’s Registrable Securities where such transferee or assignee is (i) a Subsidiary or Affiliate of such Holder or, where the Holder is a limited or general partnership, where such transferee or assignee is a constituent Affiliated limited or general partner or retired partner of the Holder or an Affiliated partnership,(ii) a Major Investor, (iii) any member or former member of any Holder, where the Holder is a limited liability company, or (iv) any family member or trust for the benefit of any Holder, where the Holder is an individual; in each case provided, that: (i) the transfer may otherwise be effected in accordance with applicable Securities Laws and the Shareholders Agreement; (ii) the Corporation is given written notice at least three Business Days prior to such transfer stating the name and address of the transferee and identifying the securities with respect to which such registration rights are being transferred; (iii) the transferee agrees in writing to be bound by the provisions of this Agreement and, to the extent required under the Shareholders’ Agreement, by the provisions of the Shareholders Agreement; and (iv) the total number of registrations to be exercised by all persons under this Agreement may not be increased other than in accordance with the terms of this Agreement.

3.5 Co-operation

Each Holder requesting inclusion of Registrable Securities in a registration statement will furnish to the Corporation information regarding such Holder as the Corporation, acting reasonably, may from time to time request in writing, and will do such reasonable acts and things as the Corporation may from time to time request, with respect to any registration, qualification or compliance referred to in this Agreement and in order to permit the Corporation to comply with the requirements of applicable Laws.

16

3.6 Termination of Registration Rights

All obligations of the Corporation (except those pursuant to Article 6) shall terminate and be of no further force and effect on the date which is the earlier of (i) the closing of a Liquidation Event, as such term is defined in the Articles of Incorporation; (ii) such time after the consummation of a Qualified IPO as Rule 144 or another similar exemption under the Securities Act is available for the sale of all such Holder’s shares without limitation during a three-month period without registration,; or (iii) the date which is three years after the date of completion of a Qualified IPO (as such term is defined in the Articles of Incorporation).

3.7 Limitations on Subsequent Registration Rights.

From and after the date of this Agreement, the Corporation shall not, without the prior written consent of the Holders of the majority of Registrable Securities, on anAs-Converted Basis, (i) enter into any other agreement with any holder or prospective holder of any securities of the Corporation which would allow such holder or prospective holder to participate in any registration of securities of the Corporation or (ii) enter into any agreement, take any action, or permit any change to occur, with respect to its securities that violates, subordinates or otherwise affects the rights granted to the Holders of the Registrable Securities in this Agreement.

6.1 Indemnification Provided by the Corporation in Favour of the Holders

In the event any Registrable Securities are included in a registration statement under this Agreement, the Corporation will indemnify, to the extent permitted by applicable law, each Holder that participates in such offering, each of its officers and directors and partners (or, in the case of a Holder that is a limited partnership, each of the partners and the officers and directors of the general partner of the limited partnership and its affiliates), each person controlling any Holder within the meaning of Section 15 of the U.S. Securities Act or Section 20 of the U.S. Exchange Act, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the U.S. Securities Act or Section 20 of the U.S. Exchange Act (collectively, the “Holder Indemnified Parties”), against all expenses, claims, losses, damages and liabilities (or actions in respect of expenses, claims, losses, damages or liabilities), including any of the foregoing incurred in settlement of any litigation, commenced or threatened,arising out of or based on (i) any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular “free writing prospectus” (as defined in

22

Rule 405 under the U.S. Securities Act) or other document, or any amendment or supplement to any document, incident to the registration, qualification or compliance, or (ii) any omission (or alleged omission) to state in a document a material fact required to be stated or necessary to make the statements, in light of the circumstances in which they were made, not misleading, or any violation by the Corporation of the U.S. Securities Laws, the Canadian Securities Laws, or any rule or regulation promulgated under any Laws applicable to the Corporation in connection with any registration, qualification or compliance, andin each case the Corporation will reimburse each of such Holder Indemnified Parties, for any legal and any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating, preparing or defending any such claim, loss, damage, liability or action,provided, however, that the indemnity contained in this Section 6.1 will not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Corporation, which consent will not be unreasonably withheld and provided that the Corporation will not be liable in any case to the extent that any claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Corporation by any Holder, controlling person thereof or underwriter to be specifically for use in any such document; and provided further, however, that the foregoing indemnity is subject to the condition that, insofar as it relates to any untrue statement, alleged untrue statement, omission or alleged omission made in a prospectus on file with the Commissions at the time the registration statement becomes effective or the amended prospectus filed with the SEC pursuant to Rule 424(b) under the U.S. Securities Act (the “Final Prospectus”), that indemnity will not enure to the benefit of any underwriter or any Holder, if there is no underwriter, if any such underwriter or Holder failed to furnish a copy of the Final Prospectus to the person asserting the loss, liability, claim or damage at or prior to the time the action is required by the applicable Securities Laws, and if the Final Prospectus would have cured the defect giving rise to the loss, liability, claim or damage. The indemnification provided for under this Section 6.1 shall remain in full force and effect regardless of any investigation made by or on behalf of any of the Holder Indemnified Parties and shall survive the transfer of the Registrable Securities by the Investors and their transferees.

6.2 Indemnification Provided by the Holders in Favour of the Corporation

In the event any Registrable Securities are included in a registration statement under this Agreement, each Holder will, if Registrable Securities held by that Holder are included in the securities as to which the registration, qualification or compliance is being effected, indemnify, to the extent permitted by applicable law, the Corporation, each of its directors and officers, each underwriter, if any, of the Corporation’s securities covered by that registration statement, each person who controls the Corporation or the underwriter within the meaning of Section 15 of the U.S. Securities Act or Section 20 of the U.S. Exchange Act, and the other Holders selling securities in such registration statement, each of its officers and directors and partners (or, in the case of a Holder that is a limited partnership, each of the partners and the officers and directors of the general partner of the limited partnership and its affiliates) and each person controlling such other Holders within the meaning of Section 15 or Section 20 of the U.S. Securities Act, against all expenses, claims, losses, damages and liabilities (or actions in respect of expenses, claims, losses, damages and liabilities), including any of the foregoing incurred in settlement of any litigation, commenced or threatened,arising out of or based on (i) any untrue statement (or alleged untrue statement), of a material fact contained in any registration statement, prospectus, offering circular, “free writing

23

prospectus” (as defined in Rule 405 under the U.S. Securities Act) or other document, or any amendment or supplement to any document incident to the registration, qualification or compliance, or (ii) any omission (or alleged omission) to state in a document a material fact required to be stated or necessary to make the statements, in light of the circumstances in which they were made, not misleading,in each case to the extent, but only to the extent, that each untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in a registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Corporation by the Holder and to be specifically for use in any such document, andin each case such Holder will reimburse the Corporation, the other Holders, the directors, officers, partners, underwriters or control persons for any legal or any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating or defending any claim, loss, damage, liability or action,provided, however, that the indemnity contained in this Section 6.2 will not apply to amounts paid in settlement of any loss, claim, damage, liability or action if the settlement is effected without the consent of the Holder, which consent will not be unreasonably withheld; provided, that the obligation to indemnify under this Section 6.2 shall be several, not joint and several, for each Holder and shall be limited to the net proceeds (after underwriting fees, commissions or discounts) actually received by such Holder from the sale of the Registrable Securities pursuant to such registration.

6.3 Indemnification Procedure

(a) Each party entitled to indemnification under this Article 6 (the “Indemnified Party”) will give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after that Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and, if the Indemnifying Party acknowledges its liability hereunder, will permit the Indemnifying Party to assume the defense of any claim or any litigation, provided that counsel for the Indemnifying Party, who will conduct the defense of the claim or litigation, will be approved by the Indemnified Party (whose approval will not be unreasonably withheld), and the Indemnified Party may participate in the defense at that party’s expense, and provided further that the failure of any Indemnified Party to give notice as provided in this Agreement will not relieve the Indemnifying Party of its obligations under this Agreement unless the failure to give the notice is materially prejudicial to an Indemnifying Party’s ability ‘to defend that action and provided further, that the Indemnifying Party will not assume the defense for matters in which there is, in the reasonable opinion of outside counsel to the Indemnified Party, a conflict of interest or separate and different defenses. No Indemnifying Party, in the defense of any such claim or any resulting litigation, will, 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 from the claimant or plaintiff to the Indemnified Party of a release from all liability in respect of the claim or litigation.

(b) If the indemnification provided for in this Article 6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying the Indemnified Party hereunder, will contribute to the

24

amount paid or payable by the Indemnified Party as a result of the loss, liability, claim, damage, or expense in the proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in the loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party will be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent the statement or omission, provided however, that, in any case, (i) no Holder will be required to contribute any amount in excess of the gross proceeds of all the Registrable Securities offered and sold by the Holder pursuant to the registration statement that are received by such Holder; and (ii) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the U.S. Securities Act) will be entitled to contribution from any person or entity who was not guilty of fraudulent misrepresentation.

(c) The obligations of the Corporation and the Holders under this Article 6 shall survive the completion of any offering of Registrable Securities in a registration statement under Article 3 of this Agreement.
