Except as provided by Law, during the period commencing on the Closing Date and ending on the second anniversary of the Closing Date, neither Sellers nor their Affiliates shall directly or indirectly solicit any person who was an employee or subcontractor of any of the NGX/Shorcan Companies or the Business on the date hereof or the Closing Date (a “Restricted Person”) to terminate his or her employment with, or otherwise cease his or her relationship with, any of the NGX/Shorcan Companies or the Business or to become an employee of any Seller or any of its Affiliates; provided that nothing in this Section 6.5 ‎shall prohibit Sellers or any of their Affiliates from (A) engaging in general solicitations to the public or general advertising not targeted at any Restricted Person, (B) soliciting any Restricted Person whose employment or engagement has been terminated by any NGX/Shorcan Company following the Closing other than as a response to any inducement or encouragement by any Seller or any of its Affiliates or (C) soliciting any Restricted Person whose employment or engagement with any NGX/Shorcan Company has been terminated by the Restricted Person following the Closing other than as a response to any inducement or encouragement by any Seller or any of its Affiliates (but only after at least ninety (90) days have passed since the date of termination of employment or engagement).

SECTION 6.6    Further Assurances. After the Closing Date, Sellers and Purchaser shall use their commercially reasonable efforts from time to time to do, make, execute and deliver, or cause to be done, made, executed and delivered, at the reasonable request of the other Party, such further acts, assurances, additional documents and instruments (including any assignments, bills of sale, assumption agreements, consents and other similar instruments in addition to those required by this Agreement) as may be reasonably required to give effect to this Agreement and the transactions contemplated hereby, and to provide whatever documents or other evidence of ownership as may be reasonably requested by Purchaser to confirm Purchaser’s ownership of the NGX/Shorcan Companies.

SECTION 6.7    Intercompany Agreements; Intercompany Accounts.

(a)    Except as set forth in Section 6.7 of the Sellers Disclosure Letter or as otherwise expressly set forth in this Agreement or the Related Agreements, Sellers shall, and

shall cause their Affiliates to, immediately prior to the Closing, execute and deliver such releases, termination agreements and discharges (in forms reasonably acceptable to Purchaser) as are necessary to release and discharge each NGX/Shorcan Company from any and all Liabilities owed to either Seller or any of their Affiliates (other than any NGX/Shorcan Company). In addition, Sellers shall, and shall cause their Affiliates to, immediately prior to the Closing, execute and deliver such releases, termination agreements and discharges (in a form reasonably acceptable to Purchaser) as are necessary to (i) release and discharge Sellers and each of their Affiliates (other than the NGX/Shorcan Companies) from any and all obligations owed to any NGX/Shorcan Company and (ii) terminate all arrangements, commitments, contracts and understandings among Sellers and any of their Affiliates, on the one hand, and any NGX/Shorcan Company, on the other hand, in each case other than those set forth on Section 6.7 of the Sellers Disclosure Letter or as otherwise expressly set forth in this Agreement or the Related Agreements.

(b)    On or prior to the Closing Date, all intercompany accounts between either Seller and/or any of their Subsidiaries (other than any NGX/Shorcan Company), on the one hand, and any NGX/Shorcan Company, on the other hand, shall be settled or otherwise eliminated (other than intercompany accounts that arise out of services performed pursuant to Contracts identified in Section 4.15(a)(xiv) of the Sellers Disclosure Letter, which shall remain outstanding in accordance with their terms). Intercompany accounts between and among the NGX/Shorcan Companies shall not be affected by this provision.

SECTION 6.8    Transfer of Intellectual Property Assets. Prior to the Closing, Seller shall, and shall cause its Affiliates to, validly and effectively assign, at no cost, all right, title and interest in and to the Intellectual Property listed in Section 6.8 of the Sellers Disclosure Letter to an NGX/Shorcan Entity.

SECTION 6.9    Retained Business Assets. If, within twelve (12) months following the Closing, any right, property, asset or interest forming part of the Business, which would have needed to be directly or indirectly assigned, transferred or otherwise provided to a NGX/Shorcan Entity in order for the representation and warranty set forth in Section 4.20(b) to be true, is identified by Purchaser or Sellers, then the applicable Party shall notify the other in writing, and, upon the request of Purchaser, (i) to the extent such right, property, asset or interest exclusively forms part of the Business, Sellers shall assign and transfer, or shall cause their applicable Affiliate to assign and transfer, at no cost, all of such right, property, asset or interest as soon as practicable to Purchaser or an Affiliate of Purchaser as designated by Purchaser and (ii) to the extent such right, property, asset or interest does not exclusively form part of the Business, Sellers shall provide, or shall cause their applicable Affiliate to provide, at no cost, all of the rights, benefits and enjoyment of such right, property, asset or interest as soon as practicable to Purchaser or an Affiliate of Purchaser as designated by Purchaser; provided, however, that this Section 6.9 shall not apply to any service that is provided or that reasonably could have been provided as an Additional Service (as defined in the Transition Services Agreement) under the Transition Services Agreement.

SECTION 6.10    Employee Matters.

(a)    For the one year period following the Closing Date, Purchaser will provide, or cause one of its Affiliates to provide, each Business Employee who is employed as of the Closing (each a “Continuing Employee”), for so long as he/she remains employed with Purchaser or one of its Affiliates (including any NGX/Shorcan Company) during such one year period, with (A) base salary at least equal to the base salary provided to the Continuing Employees immediately prior to the Closing and (B) benefits (other than equity compensation or defined benefit pension benefits) that, taken as a whole, are comparable in the aggregate to those provided to Continuing Employees immediately prior to the Closing.

(b)    Except to the extent necessary to avoid the duplication of benefits, Purchaser shall recognize the service of each Continuing Employee with any NGX/Shorcan Company before the Closing Date as if such service had been performed with Purchaser or its Affiliates (i) for all purposes under the Company Benefit Plans maintained by Purchaser or its Affiliates after the Closing Date (to the extent such plans, programs, or agreements are delivered to Continuing Employees), (ii) for purposes of eligibility and vesting under any employee benefit plans and programs of Purchaser or its Affiliates other than the Company Benefit Plans (the “New Benefit Plans”) in which the Continuing Employee participates after the Closing Date, and (iii) for benefit accrual purposes under any New Benefit Plan that is a vacation or severance plan in which the Continuing Employee participates after the Closing Date.

(c)    With respect to any welfare plan maintained by Purchaser or its Affiliates in which Continuing Employees are eligible to participate after the Closing, Purchaser and its Affiliates shall use commercially reasonable efforts to (i) waive all limitations as to preexisting conditions and exclusions with respect to participation and coverage requirements applicable to such employees to the extent such conditions and exclusions were satisfied or did not apply to such employees under the welfare plans maintained by the NGX/Shorcan Companies prior to the Closing and (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid prior to the Closing in satisfying any analogous deductible or out-of-pocket requirements to the extent applicable under any such plan.

(d)    Notwithstanding anything in this Section 6.10 to the contrary, nothing contained herein, whether express or implied, shall be treated as an amendment or other modification of any Company Benefit Plan or any employee benefit plan of Purchaser or its Affiliates, or shall limit the right of Purchaser or its Affiliates to amend, terminate or otherwise modify any such Company Benefit Plan or employee benefit plan of Purchaser or its Affiliates following the Closing in accordance with the terms and conditions of such plans. If (i) a party other than the Parties makes a claim or takes other action to enforce any provision in this Agreement as an amendment to any such plan, and (ii) such provision is deemed to be an amendment to such plan even though not explicitly designated as such in this Agreement, then, solely with respect to such plan, such provision shall lapse retroactively and shall have no amendatory effect with respect thereto. The Parties acknowledge and agree that all provisions contained in this Section 6.10 are included for the sole benefit of the Parties, and that nothing in this Agreement, whether express or implied, shall create any third-party beneficiary or other

rights (A) in any other Person, including, without limitation, any Continuing Employee, any participant in any Company Benefit Plan or any employee benefit plan of Purchaser or its Affiliates, or any dependent or beneficiary thereof, or (B) to continued employment with Purchaser or any of its Affiliates.

SECTION 6.11    Directors’ and Officers’ Indemnification.

(a)    For a period of six (6) years from and after the Closing, Purchaser shall cause the NGX/Shorcan Companies to indemnify and hold harmless, and provide advancement of expenses to, all past and present directors and officers of any NGX/Shorcan Company as of the date hereof and anyone who becomes a director or officer of any NGX/Shorcan Company during the period from the date of this Agreement through the Closing (in such capacities) (the “D&O Indemnified Persons”) for all acts and omissions occurring at or prior to the Closing to the same extent such D&O Indemnified Persons are indemnified or have the right to advancement of expenses as of the date of this Agreement by the NGX/Shorcan Companies pursuant to the organizational documents of any applicable NGX/Shorcan Company as in existence on the date hereof, in each case, to the fullest extent that such indemnification and advancement is permitted by applicable Law. Purchaser shall cause the organizational documents of the NGX/Shorcan Companies to contain provisions with respect to indemnification, advancement of expenses and limitation of director and officer liability that are no less favorable to the D&O Indemnified Persons with respect to acts or omission occurring at or prior to the Closing than those set forth in the organizational documents of the NGX/Shorcan Companies as of the date of this Agreement, which provisions thereafter shall, subject to applicable Law, not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of any D&O Indemnified Persons for a period of six (6) years from and after the Closing. From and after the Closing, Purchaser shall cause the NGX/Shorcan Companies to honor, in accordance with their respective terms, each of the covenants contained in this Section 6.11.

(b)    If Purchaser, the NGX/Shorcan Companies or any of its or their successors or assigns (i) shall consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or other entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any Person, then, in each such case, proper provisions shall be made so that the successors and assigns of Purchaser or the NGX/Shorcan Companies, as the case may be, shall assume all of the obligations set forth in this Section 6.11.

(c)    The obligations of Purchaser, the NGX/Shorcan Companies and any successors thereto under this Section 6.11 shall not be terminated or modified in such a manner as to adversely affect any D&O Indemnified Person to whom this Section 6.11 applies without the consent of such affected D&O Indemnified Person (it being expressly agreed that the D&O Indemnified Persons to whom this Section 6.11 applies shall be third-party beneficiaries of this Section 6.11).

SECTION 6.12    Backstop Agreements. Each Party shall use its commercially reasonable efforts to procure the satisfaction of Section 7.1(d) in respect of the backstop agreements specified in Section 6.12 of the Sellers Disclosure Letter (the “Backstop Agreements”); provided that if any alternative arrangement referenced in Section 7.1(d)(ii) (a) would require Sellers or their Affiliates to make any payment or incur any third-party costs (except if Purchaser agrees to reimburse such payment or costs), (b) would reasonably be expected to require any material clearance, consent, approval, order, license or authorization of, or declaration, registration or filing with, or notice to, or permit issued by, any Governmental Authority which cannot reasonably be expected to be made or procured by Sellers and their Affiliates, or (c) cannot reasonably be achieved within 45 days of the date of this Agreement (which time period, for the avoidance of doubt, includes the time required to make or procure any clearance, consent, approval, order, license or authorization of, or declaration, registration or filing with, or notice to, or permit issued by, any Governmental Authority), then Purchaser shall not pursue such alternative arrangement and shall use its commercially reasonable efforts to procure the satisfaction of Section 7.1(d)(i) in respect of the applicable Backstop Agreement.

SECTION 6.13    Sublease Agreement. Sellers shall use their commercially reasonable efforts, and shall cause TSX Venture Exchange Inc. to use its commercially reasonable efforts, to obtain the consent (the “Landlords’ Consent”) of The Great-West Life Assurance Company and ASET Properties Inc. (together, the “Landlords”) to enter into a sublease agreement with NGX substantially in the form attached as Exhibit C (a “Sublease Agreement”). If, prior to the Closing, Sellers have obtained the Landlords’ Consent to enter into a Sublease Agreement, then Sellers shall cause TSX Ventures Exchange Inc. and NGX to enter into a Sublease Agreement (with such changes reasonably requested by the Landlords and consented to by the Purchaser, such consent not to be unreasonably withheld, conditioned or delayed) with effect as of the Closing. If Sellers have not obtained the Landlords’ Consent prior to the Closing, then from and after the Closing (i) for a period not to exceed 100 days in total (including the time prior to the Closing) (A) Sellers shall continue to use their commercially reasonable efforts, and shall cause TSX Venture Exchange Inc. to use its commercially reasonable efforts, to obtain the Landlords’ Consent and (B) once the Landlords’ Consent has been obtained, Sellers shall cause TSX Venture Exchange Inc. and Purchaser shall cause NGX to enter into a Sublease Agreement (with such changes reasonably requested by the Landlords and consented to by the Purchaser, such consent not to be unreasonably withheld, conditioned or delayed) and (ii) Sellers shall provide the space that would have been subleased pursuant to the terms of such a sublease agreement as an Additional Service (as defined in the Transition Services Agreement) to Purchaser under the Transition Services Agreement, and Purchaser shall pay the per square foot per annum price for such space pursuant to the Sublease Agreement, until the earlier date of (A) the date on which the Landlords’ Consent has been obtained and such a Sublease Agreement has become effective and (B) October 30, 2020.

SECTION 6.14    Preservation of Privilege. Recognizing that Wilmer Cutler Pickering Hale and Dorr LLP and the other law firms specified in Section 6.14 of the Sellers Disclosure Letter (“Seller Counsel”) has acted as legal counsel to Sellers and their Affiliates

(including the NGX/Shorcan Companies) in connection with the negotiation, execution and delivery of this Agreement and the consummation of the Sale (the “Pre-Closing Representation”), and that Seller Counsel intends to or may continue to act as legal counsel to Sellers and their Affiliates after the Closing (which Affiliates shall not include the NGX/Shorcan Companies after the Closing), the Parties hereby agree that after the Closing any attorney-client privilege attaching to communications between Sellers, Sellers’ Affiliates or the NGX/Shorcan Companies, on the one hand, and Seller Counsel, on the other hand, to the extent such communications relate to the Pre-Closing Representation, shall belong to and be controlled by Sellers, and following the Closing, none of Purchaser nor its Affiliates (which Affiliates shall include the NGX/Shorcan Companies after the Closing) shall knowingly access any such privileged communications.

SECTION 6.15    Exclusivity. From the date of this Agreement until the Closing, or the earlier termination of this Agreement in accordance with its terms, Sellers shall not, and Sellers shall procure that their representatives, Affiliates (including the NGX/Shorcan Companies) and Affiliates’ representatives will not, directly or indirectly: (a) solicit, initiate, or encourage the submission of any proposal or offer from any Person relating to, or enter into or consummate any transaction relating to, the acquisition of any Securities in the NGX/Shorcan Companies or any merger, recapitalization, share exchange, sale of all or substantially all of the NGX/Shorcan Companies’ assets (other than sales of inventory in the Ordinary Course) or any similar transaction or any other alternative to the Sale or (b) participate in any substantive discussions or negotiations regarding, furnish any information with respect to, assist or participate in, or facilitate in any other manner, any effort or attempt by any Person to do or seek any of the foregoing. Sellers shall, and shall cause their Affiliates and their and their Affiliates’ representatives to, immediately discontinue any conduct that would if continued after the date hereof violate any aspect of the immediately preceding sentence.

SECTION 6.16    Notification of Certain Matters. From the date of this Agreement until the earlier of the Closing Date and the termination of this Agreement in accordance with its terms, Sellers shall promptly deliver to Purchaser notice (including a reasonably detailed description) of any fact, circumstance or development that constitutes (or would reasonably be expected to constitute or result in) any breach of any representation, warranty or covenant set forth herein that would result in the non-satisfaction of any condition set forth in Article VII. No such notice shall be deemed to avoid or cure any breach of representation, warranty or covenant or constitute an amendment of any representation, warranty, covenant or condition in this Agreement or the Sellers Disclosure Letter.

SECTION 6.17    NGX Consent. Prior to the Closing, Sellers shall cause the board of directors of NGX to approve the transfer of one hundred percent (100%) of the equity interests in NGX pursuant to the terms of this Agreement.

SECTION 7.1    Conditions of All Parties to Closing. The respective obligations of each Party hereunder to consummate the Sale shall be subject to the fulfillment (or, if legally permissible, mutual waiver by Sellers and Purchaser), prior to or at the Closing, of each of the following conditions:

(a)    No Injunction. No Order that prohibits the consummation of the Sale shall have been entered and shall continue to be in effect.

All conditions required to be satisfied pursuant to Article VII of the Trayport Agreement shall have been either satisfied (other than those conditions that by their nature are to be satisfied at the Closing (as defined in the Trayport Agreement)) or waived (if permissible).

(d)    Backstop Agreements. With respect to each Backstop Agreement, either (i) (A) Purchaser shall have substituted itself or had one of its Affiliates substituted for Sellers and any of their Affiliates (other than any NGX/Shorcan Company), and for Sellers and any of their Affiliates (other than any NGX/Shorcan Company) to be released, effective as of the Closing, in respect of all obligations of Sellers and any of their Affiliates (other than any NGX/Shorcan Company) under such Backstop Agreement (in a form reasonably acceptable to Purchaser and Sellers) and (B) any consent or approval by a counterparty to such Backstop Agreement required in connection with the consummation of the transactions contemplated by this Agreement shall have been received, or (ii) subject to Section 6.12, Purchaser shall have replaced such Backstop Agreement with an alternative arrangement reasonably acceptable to Purchaser and Sellers.

on and as of the Closing Date and (iii) the other representations and warranties of Sellers contained in Article IV shall be true and correct (without giving effect to any limitation as to “materiality,” “Material Adverse Effect” or similar materiality qualifiers set forth therein) as of the date hereof and as of the Closing Date as though made on and as of the Closing Date (except that those representations and warranties which address matters only as of a particular date shall be true and correct only as of such particular date), except in the case of this clause (iii), where the failure to be so true and correct would not have, and would not reasonably be expected to have, a Business Material Adverse Effect.

(b)    The covenants and agreements of Sellers to be complied with on or prior to the Closing pursuant to the terms of this Agreement shall have been complied with in all material respects.

(c)    Purchaser shall have received at the Closing a certificate dated the Closing Date and validly executed on behalf of each Seller by an appropriate executive officer of such Seller certifying that the conditions specified in Section 7.2(a) and Section 7.2(b) have been satisfied.

(b)    Purchaser covenants to pay or cause to be paid an amount equal to, or shall be liable for, and shall indemnify, defend and hold Sellers and their Affiliates harmless from and against (i) any and all liabilities for Taxes with respect to the NGX/Shorcan Companies other than Excluded Taxes that are the responsibility of Sellers under Section 8.1(a), including any reasonable out-of-pocket fees, costs and expenses of any outside attorneys, accountants or other external tax advisors with respect thereto, and (ii) any and all Damages incurred by Sellers or any of their Affiliates to the extent arising out of or resulting from the breach of an agreement or covenant made in this Article VIII by Purchaser.

(c)    Payment in full of any amount due from Sellers or Purchaser under this Section 8.1 shall be made to the affected party in immediately available funds within fifteen (15) days after written demand is made for such payment; provided, however, that no such amounts due are required to be paid prior to three (3) Business Days before such amounts are required to be paid to the relevant Taxing Authority.

SECTION 8.2    Preparation and Filing of Tax Returns.

(a)    Sellers shall timely prepare or shall cause to be timely prepared (i) any combined, consolidated or unitary Tax Return that includes Sellers or any of their Affiliates and

(ii) any Tax Return of any NGX/Shorcan Company for any taxable period that ends on or before the Closing Date. Subject to Section 8.5, and except as otherwise provided in Section 8.2(g)(ii), Sellers shall deliver to Purchaser for its review, comment and approval (which approval shall not be unreasonably withheld) a copy of such proposed Tax Return (x) in the case of Tax Returns prepared less frequently than on a quarterly basis, at least ten (10) Business Days prior to the due date (giving effect to any validly obtained extension thereof) and (y) in the case of Tax Returns prepared on a quarterly or more frequent basis, at least five (5) Business Days prior to the due date thereof (giving effect to any validly obtained extension thereof). If Purchaser does not approve of the filing of any Tax Return described in this Section 8.2(a), Purchaser shall provide written notice to Sellers at least three (3) Business Days prior to the anticipated filing date of such Tax Return, and any such dispute shall be subject to the dispute procedures set forth in Section 8.2(h). Subject to Section 8.2(h) with respect to any disputed item, Sellers shall timely file or shall cause to be timely filed any Tax Return described in clause (i) of the first sentence of this Section 8.2(a) and shall deliver to Purchaser, and Purchaser shall timely file or cause to be timely filed in the manner prepared by Sellers, any Tax Returns described in clause (ii) of the first sentence of this Section 8.2(a). Except to the extent specifically reflected as a Tax liability in the determination of the Closing Working Capital, Sellers shall pay, or cause to be paid, to the appropriate Taxing Authority any amounts shown as due on the Tax Returns described in this Section 8.2(a).

(b)    Purchaser shall, except to the extent that such Tax Returns are the responsibility of Sellers under Section 8.2(a), timely prepare and file or shall cause to be timely prepared and filed all Tax Returns with respect to any NGX/Shorcan Company.

(c)    For any Straddle Period Tax Return of any NGX/Shorcan Company that is the responsibility of Purchaser under Section 8.2(b), except as otherwise provided in Section 8.2(f), (1) such Straddle Period Tax Returns shall be prepared consistent with the past practice of the NGX/Shorcan Companies immediately prior to the Closing Date (after taking into account any actions taken pursuant to Section 8.2(g)), and (2) Purchaser shall deliver to Sellers for their review, comment and approval (which approval shall not be unreasonably withheld) a copy of such proposed Tax Return (accompanied by an allocation between the Pre-Closing Period and the Post-Closing Period of the Taxes shown to be due on such Tax Return) (i) in the case of Tax Returns prepared less frequently than on a quarterly basis, at least ten (10) Business Days prior to the due date (giving effect to any validly obtained extension thereof) and (ii) in the case of Tax Returns prepared on a quarterly or more frequent basis, at least five (5) Business Days prior to the due date thereof (giving effect to any validly obtained extension thereof). Sellers shall pay to Purchaser the amount of Taxes shown as due on such Tax Returns that are Excluded Taxes within three (3) Business Days of the due date of such Tax Returns.

(d)    Except to the extent required by applicable Law, Purchaser shall not, and shall cause its Subsidiaries not to, amend any Tax Return of any NGX/Shorcan Company for any Pre-Closing Period or for any Straddle Period without the consent of Sellers, which consent shall not be unreasonably withheld, conditioned or delayed.

(e)    The Parties agree that this Article VIII expressly permits and contemplates that Purchaser shall file such Tax Returns (including, for the avoidance of doubt, the making of any business registrations to facilitate the filing of any such Tax Returns or the receipt or delivery of any other form of Tax certificate) that Purchaser determines should be filed with respect to taxable periods beginning after the Closing Date, and the Parties expressly acknowledge that this Article VIII permits and contemplates that the filing of such Tax Returns and making of such business registrations, and the manner in which such Tax Returns are completed and filed, may be inconsistent with the past practice of the NGX/Shorcan Companies prior to the Closing Date. Accordingly, any such filing or registration shall not cause any Taxes imposed on or payable with respect to the NGX/Shorcan Companies (including any Taxes imposed as a transferee or successor or by Contract) in respect of any Pre-Closing Period to fail to constitute Excluded Taxes under this Agreement.

(f)    Without limiting Section 8.2(e), for a period of eighteen (18) months following the Closing Date, to the extent Purchaser intends to take a position on any Tax Return with respect to any taxable period ending after the Closing Date that materially departs from the past practice of the NGX/Shorcan Companies immediately prior to the Closing Date (after taking into account any actions taken pursuant to Section 8.2(g) or any determinations of the Tax Referee pursuant to Section 8.2(h)), Purchaser shall use commercially reasonable efforts to notify Sellers in writing as soon as reasonably practicable of such intention. If (x) Sellers reasonably object in writing to any such position within five (5) Business Days of the date such notification is sent by Purchaser, and (y) within ten (10) Business Days of the date such notification is sent by Purchaser, Sellers provide written advice from a nationally or internationally recognized law firm or a “Big Four” accounting firm, in each case experienced as to such matters, that Sellers’ proposed position with respect any such disputed item is at least more likely than not to be sustained under applicable Tax Law, such matter shall be subject to the dispute procedures set forth in Section 8.2(h). If Sellers either (i) do not provide written notice objecting to the taking of any such position within five (5) Business Days of the date such notification is sent to Sellers or (ii) do not provide written advice from a nationally or internationally recognized law firm or a “Big Four” accounting firm within ten (10) Business Days of the date such notification is sent to Sellers, Sellers shall be deemed to have consented to the position set forth in such notification. Subject to Section 8.2(h) in the case of any disputed item, Purchaser shall deliver to Sellers for their review and comment a copy of any such proposed Tax Return described in this Section 8.2(f) (i) in the case of Tax Returns prepared less frequently than on a quarterly basis, at least ten (10) Business Days prior to the due date (giving effect to any validly obtained extension thereof) and (ii) in the case of Tax Returns prepared on a quarterly or more frequent basis, at least five (5) Business Days prior to the due date thereof (giving effect to any validly obtained extension thereof). Purchaser shall consider in good faith any comments received by Sellers at least three (3) Business Days prior to the due date for such Tax Return.

(g)    

(i)    Prior to the Closing Date, Sellers shall take the following actions as are necessary in order to remedy or adjust certain Tax filing positions taken by the NGX/Shorcan Companies with respect to Pre-Closing Periods:

(1)    Sellers shall use commercially reasonable efforts to review the Tax positions taken by each of the NGX/Shorcan Companies in each U.S. federal, state and local and Canadian federal, provincial and local jurisdiction in which each of the NGX/Shorcan Companies is currently not registered with applicable Taxing Authorities to determine whether registration is likely required for any Taxes in such jurisdiction.

(2)    Sellers shall cause each of the NGX/Shorcan Companies to register with applicable Taxing Authorities for all U.S. federal, state and local and Canadian federal, provincial and local Taxes for which such NGX/Shorcan Company is currently not registered, in each case where Purchaser and Sellers agree at least twenty (20) Business Days prior to the Closing Date that registration is likely required (or that are determined by the Tax Referee pursuant to Section 8.2(h) at least twenty (20) Business Days prior to the Closing Date to be likely required).

(3)    Sellers shall use commercially reasonable efforts to contact the customers of the NGX/Shorcan Companies to obtain tax exemption certificates (resale exemptions/manufacturing exemptions or other applicable exemption certificates) from any such customers that may be eligible for an exemption and for which an exemption certificate may be required. Sellers shall provide copies of any such exemptions certificates to Purchaser promptly upon receipt. Sellers shall take into account any comments received by Purchaser in assessing the validity of any such exemption certificates.

(4)    Sellers shall use commercially reasonable efforts to provide to Purchaser a list of “end user” customers that may be liable for U.S. federal, state and local or Canadian federal, provincial or local Taxes on the sale of commodities or services, which Taxes would be required to be collected from such customers by any of the NGX/Shorcan Companies, and the Parties shall cooperate to determine how to communicate any changes to customers regarding the taxability of any transactions with customers and the timing for imposing any Tax with respect to such transactions.

(5)    Sellers shall use commercially reasonable efforts to provide Purchaser with the notional value of commodities or services sold to U.S. customers, by state and local Tax jurisdiction.

(ii)    Purchaser and Sellers shall reasonably cooperate with each other in taking the actions set forth in Section 8.2(g)(i). Prior to submitting any Tax Return or other information to any Taxing Authority with respect to U.S. federal, state and local or Canadian federal, provincial or local Taxes of any NGX/Shorcan Company in a

jurisdiction in which such NGX/Shorcan Company (a) has not previously filed a Tax Return with respect to such Taxes or (b) has previously filed but is not currently filing a Tax Return with respect to such Taxes, Sellers shall use commercially reasonable efforts to deliver to Purchaser for its review and comment a copy of any such proposed Tax Return or information (1) in the case of Tax Returns required to be prepared less frequently than on a quarterly basis, at least ten (10) Business Days prior to the anticipated filing date for such Tax Return or the anticipated date for submitting such other information and (2) in the case of Tax Returns required to be prepared on a quarterly or more frequent basis, at least five (5) Business Days prior to the anticipated filing date for such Tax Return or the anticipated date for submitting such other information. Sellers shall consider in good faith any comments received by Purchaser at least three (3) Business Days prior to the anticipated filing date for such Tax Return or the anticipated date for submitting such other information. If, with respect to any action set forth in this Section 8.2(g)(ii) that could adversely impact Purchaser or its Affiliates (including, after the Closing Date, the NGX/Shorcan Companies) following the Closing Date, (x) Purchaser reasonably objects in writing to the filing of any such Tax Return (including with respect to any item of information contained in any such Tax Return or the positions set forth on any such Tax Return) or providing such information described in this Section 8.2(g)(ii) at least five (5) Business Days prior to the anticipated filing date for such Tax Return or the anticipated date for submitting such other information and (y) Purchaser provides written advice from a nationally or internationally recognized law firm or “Big Four” accounting firm, in each case experienced as to such matters, that both (1) Purchaser’s proposed position with respect any such disputed item is at least more likely than not to be sustained under applicable Tax Law and (2) Sellers’ proposed position with respect to such disputed item is not at least more likely than not be sustained under applicable Tax Law, such matter shall be subject to the dispute procedures set forth in Section 8.2(h).

(h)    Any dispute between the Parties with respect to the matters set forth in Section 8.2(a), Section 8.2(f) or Section 8.2(g) shall be resolved by the procedures set forth in this Section 8.2(h). In the event that a Party reasonably objects in writing to the filing of any Tax Return or the submission of any information (such Party, the “Disputing Party”) by the other Party pursuant to the requirements set forth in Section 8.2(a), Section 8.2(f) or Section 8.2(g), the Parties shall negotiate in good faith to resolve such disagreement by mutual agreement or to determine whether to seek a ruling from an applicable Taxing Authority with respect to the disputed item. If the Parties are unable to reach such mutual agreement within ten (10) Business Days of the date the Disputing Party provided written notice of such dispute to the other Party, and the Parties determine to not seek a ruling from an applicable Taxing Authority (or are unable to agree on a mutually satisfactory manner for seeking a ruling from an applicable Taxing Authority), such dispute shall be resolved by a nationally or internationally recognized expert in the relevant area (i.e., that is either a law firm or KPMG or PricewaterhouseCoopers) (the “Tax Referee”), chosen and mutually acceptable to both Sellers and the Purchaser within five (5) days of the date on which the need to choose the Tax Referee arises. The Tax Referee shall resolve any disputed items and determine which of Sellers’ or Purchaser’s positions is more likely to be sustained under applicable Tax Law within ten (10) Business Days of having the item referred to

it pursuant to such procedures as it may require. In the event of a dispute governed by this Section 8.2(h), to the extent the Parties are required to take a position prior to the resolution of such disputed item, the Parties shall take positions with respect to such disputed item in a manner consistent with the past practice of the NGX/Shorcan Companies prior to the Closing Date (after taking into account any actions taken pursuant to Section 8.2(g)), and the Parties shall file such amended Tax Returns or other filings as are necessary to reflect the determination of the Tax Referee. The costs of the Tax Referee, and any penalties and interest resulting from any actions that were taken or not taken pursuant to the immediately preceding sentence, shall be borne by the party whose position was not sustained. The Parties agree that this Article VIII expressly permits and contemplates that such Tax Returns filed or information submitted to an applicable Taxing Authority pursuant to this Section 8.2(h), whether by mutual agreement or as a result of a determination of a Tax Referee, are expressly permitted and contemplated under this Article VIII, and that the filing of such Tax Returns or submission of such information, and the manner in which such Tax Returns or information are completed, filed or submitted, may be inconsistent with the past practice of the NGX/Shorcan Companies prior to the Closing Date. Accordingly, any actions taken by Purchaser pursuant to this Section 8.2(h) shall not prejudice Purchaser’s rights to indemnification from Sellers with respect to any Excluded Taxes.

SECTION 8.3    Refunds, Credits and Carrybacks.

(a)    Subject to Section 8.3(c), Sellers shall be entitled to any refunds or credits of or against any Excluded Taxes actually received by the Purchaser or the NGX/Shorcan Companies, net of any Taxes or other reasonable out-of-pocket fees, costs and expenses of any outside attorneys, accountants or external other tax advisors with respect to any such refunds or credits, except to the extent such refund or credit is reflected in the determination of Closing Working Capital. Any such Tax refunds or credits for a Straddle Period shall be apportioned between the Pre-Closing Period and the Post-Closing Period pursuant to the principles described in the definition of Excluded Taxes for allocating Taxes with respect to a Straddle Period. Purchaser shall be entitled to any refunds or credits of or against any Taxes other than refunds or credits of or against Excluded Taxes that are described in the first sentence of this Section 8.3(a).

(b)    Purchaser shall, and shall cause the NGX/Shorcan Companies to, promptly forward to Sellers or reimburse Sellers for any refunds or credits due Sellers (pursuant to the terms of this Article VIII) after receipt thereof, and Sellers shall promptly forward to Purchaser or reimburse Purchaser for any refunds or credits due Purchaser (pursuant to the terms of this Article VIII) after receipt thereof.

(c)    Purchaser agrees that, to the extent permitted by law, none of the NGX/Shorcan Companies shall elect to carry back any item of loss, deduction or credit which arises in any taxable period ending after the Closing Date (“Subsequent Loss”) into any taxable period ending on or before the Closing Date. If a Subsequent Loss is carried back into any taxable period ending on or before the Closing Date, (i) Sellers shall be entitled to any refund of Taxes realized as a result thereof to the extent such Subsequent Loss relates to or affects any Excluded Taxes or that is carried back to a Seller Group Tax Return and (ii) Purchaser shall be entitled to any other refund of Taxes resulting from such Subsequent Loss.

Section 8.4    Tax Contests.

(a)    If any Taxing Authority asserts a Tax Claim, then the Party first receiving notice of such Tax Claim promptly shall provide written notice thereof to the other Parties; provided, however, that the failure of such Party to give such prompt notice shall not relieve the other Party of any of its obligations under this Article VIII, except to the extent that the other Party is actually prejudiced thereby. Such notice shall specify in reasonable detail the basis for such Tax Claim and shall include a copy of the relevant portion of any correspondence received from the Taxing Authority.

(b)    Sellers shall have the right to control, at their own expense, any audit, examination, contest, litigation or other proceeding by or against any Taxing Authority (a “Tax Proceeding”) in respect of any NGX/Shorcan Company that relates solely to a taxable period that ends on or before the Closing Date; provided, however, that (i) Sellers shall provide Purchaser with a timely and reasonably detailed account of each stage of such Tax Proceeding, (ii) Sellers shall consult with Purchaser and offer Purchaser an opportunity to comment before submitting any written materials prepared or furnished in connection with such Tax Proceeding, (iii) Sellers shall defend such Tax Proceeding diligently and in good faith as if they were the only party in interest in connection with such Tax Proceeding, (iv) Purchaser shall be entitled to participate, at its own expense, in such Tax Proceeding and receive copies of any written materials relating to such Tax Proceeding received from the relevant Taxing Authority, and (v) Sellers shall not settle, compromise or abandon any such Tax Proceeding without obtaining the prior written consent of Purchaser, which consent shall not be unreasonably withheld.

(c)    In the case of a Tax Proceeding for a Straddle Period of any NGX/Shorcan Company, the Controlling Party shall have the right to control, at its own expense, such Tax Proceeding; provided, however, that (i) the Controlling Party shall provide the Non-controlling Party with a timely and reasonably detailed account of each stage of such Tax Proceeding, (ii) the Controlling Party shall consult with the Non-controlling Party and offer the Non-controlling Party an opportunity to comment before submitting any written materials prepared or furnished in connection with such Tax Proceeding, (iii) the Controlling Party shall defend such Tax Proceeding diligently and in good faith as if it were the only party in interest in connection with such Tax Proceeding, (iv) the Non-controlling Party shall be entitled to participate in such Tax Proceeding, at its own expense, if such Tax Proceeding could have an adverse impact on the Non-controlling Party or any of its Affiliates, and (v) the Controlling Party shall not settle, compromise or abandon any such Tax Proceeding without obtaining the prior written consent, which consent shall not be unreasonably withheld, of the Non-controlling Party if such settlement, compromise or abandonment could have an adverse impact on the Non-controlling Party or any of its Affiliates. “Controlling Party” shall mean whichever of Sellers (on the one hand) or Purchaser (on the other hand) is reasonably expected to bear the greater Tax liability in connection with a Straddle Period Tax Proceeding, and “Non-controlling Party” shall mean whichever of Sellers (on the one hand) or Purchaser (on the other hand) is not the Controlling Party with respect to such Straddle Period Tax Proceeding.

(d)    Purchaser shall have the right to control, at its own expense, any Tax Proceeding involving any NGX/Shorcan Company (other than any Tax Proceeding described in Section 8.4(b) or Section 8.4(c)).

(e)    Without limiting Purchaser’s rights under Section 8.2(e) and Section 8.2(f), Purchaser shall not make any voluntary disclosure or initiate any discussions or examinations with any Taxing Authority, in each case with respect to Taxes of any NGX/Shorcan Company for any taxable period that ends on or before the Closing Date without the prior written consent of the Sellers.

Section 8.5    Sellers Consolidated Returns. Notwithstanding any other provision of this Agreement, (a) Sellers shall, subject to this Section 8.5, be entitled to control in all respects, and neither Purchaser nor any of its Affiliates shall be entitled to participate in, any Tax Proceeding with respect to any consolidated, combined or unitary Tax Return that includes Sellers and (b) Sellers shall not be required to provide any Person with any consolidated, combined or unitary Tax Return or copy thereof that includes Sellers; provided, however, that to the extent that such Tax Returns would be required to be delivered to Purchaser and would be subject to Purchaser’s review and approval pursuant to this Agreement but for this Section 8.5, the Person that would be required to deliver such Tax Returns shall instead deliver pro forma Tax Returns relating solely to the relevant NGX/Shorcan Company and allow Purchaser to review and approve such pro forma Tax Returns (such approval not to be unreasonably withheld), and Sellers shall reflect Purchaser’s reasonable comments to such pro forma Tax Returns on the Tax Returns actually filed with Taxing Authorities.

Section 8.6    Cooperation. Each Party shall, and shall cause its Affiliates to, provide to the other Parties such cooperation, documentation and information as either of them reasonably may request in (a) filing any Tax Return, amended Tax Return or claim for refund, (b) determining a liability for Taxes or an indemnity obligation under this Article VIII or a right to refund of Taxes, (c) conducting any Tax Proceeding, (d) determining an allocation of Taxes between a Pre-Closing Period and Post-Closing Period or (e) taking any actions permitted or required to be taken pursuant to Section 8.2(e), Section 8.2(f), Section 8.2(g) or Section 8.2(h). Such cooperation and information shall include providing copies of all relevant portions of relevant Tax Returns, together with all relevant portions of relevant accompanying schedules and relevant work papers, relevant documents relating to rulings or other determinations by Taxing Authorities and relevant records concerning the ownership and Tax basis of property and other information, which any such Party may possess. Each Party will retain all Tax Returns, schedules and work papers, and all material records and other documents relating to Tax matters, of the relevant entities for their respective Tax periods ending on or prior to the Closing Date until the later of (A) the expiration of the statute of limitations for the Tax periods to which the Tax Returns and other documents relate or (B) ten years following the due date (without extension) for such Tax Returns. Thereafter, the Party holding such Tax Returns or other documents may dispose of them after offering the other Party reasonable notice and opportunity to take possession of such Tax Returns and other documents at such other Party’s own expense.

Each Party shall make its employees reasonably available on a mutually convenient basis at its cost to provide explanation of any documents or information so provided.

Section 8.7    Tax Sharing Agreements. Anything in this Agreement or any other agreement to the contrary notwithstanding, all liabilities and obligations (a) between Sellers or any of their Affiliates (other than the NGX/Shorcan Companies) on the one hand and the NGX/Shorcan Companies on the other hand, or (b) at the request of Purchaser, between any of the NGX/Shorcan Companies under any Tax allocation or Tax sharing agreement in effect prior to the Closing Date (other than this Agreement) shall cease and terminate as of the Closing Date as to all past, present and future taxable periods, and the NGX/Shorcan Companies shall thereafter not be bound thereby or have any liability thereunder and all powers of attorney of the NGX/Shorcan Companies with respect to Taxes shall be terminated as of the Closing Date and shall be of no further force of effect.

Section 8.8    Timing Differences.

(a)    Purchaser agrees that if (i) there is an audit adjustment (or adjustment in any other Tax Proceeding) made with respect to any Tax Item by any Taxing Authority with respect to Taxes for which Sellers are liable or responsible (and which liability is actually satisfied by Sellers), and (ii) as a result of such adjustment, Purchaser, the NGX/Shorcan Companies or any of their respective Subsidiaries or Affiliates receives in a Post-Closing Period an actual reduction in cash Tax liability or any Tax refund in cash, in each case, in or prior to the taxable year in which the audit or other Tax Proceeding is concluded or in the succeeding two taxable years, then Purchaser shall pay to Sellers the amount of such reduction or refund within fifteen (15) days of filing the Tax Return in which such reduction or refund is actually realized, except to the extent such reduction or refund is reflected in the determination of Closing Working Capital.

(b)    If Purchaser, the NGX/Shorcan Companies or any of their respective Subsidiaries or Affiliates receives in a Post-Closing Period an actual reduction in cash Tax liability or any Tax refund in cash arising from any deduction arising in respect of any NGX/Shorcan Transaction Expenses that are borne or paid by Sellers, Purchaser acknowledges and agrees that it will pay Sellers the amount of any such reduction or refund that results from such deduction on a Tax Return of Purchaser or any of its Affiliates (including the NGX/Shorcan Companies) in or prior to the taxable year in which the applicable Transaction Expense is paid or in the succeeding two taxable years, which amount shall be paid to Sellers within fifteen (15) days of filing the Tax Return in which such reduction or refund is actually realized, except to the extent such reduction or refund is reflected in the computation of Closing Working Capital and increases the Closing Purchase Price.

Section 8.9    Tax Treatment of Payments. Sellers, Purchaser and their respective Affiliates shall treat any and all payments under this Agreement (including for breach of warranty or representation) as an adjustment to the Closing Purchase Price for Tax purposes unless they are required to treat such payments otherwise by applicable Tax Laws. Accordingly, any reference in this Agreement to an indemnity in respect of a liability for the NGX/Shorcan Entities (or their Subsidiaries) or any obligation of the Parties to make a payment in respect of

the NGX/Shorcan Entities (or their Subsidiaries) shall be construed as a reference to a covenant by Sellers (for themselves and on behalf of its Affiliates) to pay Purchaser (for itself and on behalf of its Affiliates) an amount equal to such liability or payment.

Section 8.10    Sales and Transfer Taxes. Purchaser shall pay and be responsible for all sales, use, value-added, business, goods and services, transfer, stamp duty, documentary, conveyancing or similar taxes or expenses that may be imposed as a result of the Sale, together with any and all penalties, interest and additions to tax with respect thereto (“Transfer Taxes”), and Sellers and Purchaser shall cooperate in timely making all filings, returns, reports and forms as may be required to comply with the provisions of such Tax Laws.

Section 9.1    Termination. This Agreement may be terminated and the transactions contemplated hereby may be abandoned at any time prior to the Closing:

(a)    by the mutual written consent of Purchaser and Sellers;

(b)    (i) by either Purchaser or Sellers, upon written notification to the non-terminating Party by the terminating Party, if any Order permanently prohibiting the consummation of the Sale shall have been issued and shall have become final and non-appealable, (ii) by Sellers, upon written notification to Purchaser by Sellers, if a Governmental Authority issues an Order that prohibits the consummation of the Sale (other than where such Order is of an interim or temporary nature), and Purchaser does not seek to overturn such Order within thirty (30) days of its issuance, or (iii) by Purchaser, upon written notification to Sellers by Purchaser, if a Governmental Authority issues an Order that prohibits the consummation of the Sale (other than where such Order is of an interim or temporary nature), and Sellers do not seek to overturn such Order within thirty (30) days of its issuance; provided, however, that a Party shall not have the right to terminate this Agreement pursuant to this Section 9.1(b) if the failure by such Party or of any of its Affiliates to perform any of its material covenants or obligation under this Agreement has been the cause of, or has resulted in, such Order;

(c)    by either Purchaser or Sellers, if the Closing has not occurred by the date that is one year from the date of this Agreement (the “Outside Date”); provided, however, that neither Purchaser nor Sellers shall have the right to terminate this Agreement pursuant to this Section 9.1(c) if its failure to perform or breach of any of its material covenants, representations, warranties or obligations under this Agreement has been the cause of, or has resulted in, the failure of the Sale to occur on or before such date;

(d)    by Sellers, if Purchaser shall have breached any of its representations, warranties, covenants or agreements contained in this Agreement that would give rise to the failure of a condition set forth in Section 7.3(a) or Section 7.3(b), which breach cannot be or has not been cured within thirty (30) Business Days after the giving of written notice by Sellers to

Purchaser specifying such breach (provided that in no event shall such thirty (30) Business Day period extend beyond the Outside Date and provided that neither Seller is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement);

(e)    by Purchaser, if Sellers shall have breached any of their representations, warranties, covenants or agreements contained in this Agreement that would give rise to the failure of a condition set forth in Section 7.2(a) or Section 7.2(b), which breach cannot be or has not been cured within thirty (30) Business Days after the giving of written notice by Purchaser to Sellers specifying such breach (provided that in no event shall such thirty (30) Business Day period extend beyond the Outside Date and provided that Purchaser is not then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement);

(f)    by either Purchaser or Sellers, if the Trayport Agreement is terminated pursuant to its terms; or

(g)    by Purchaser, if the Closing has not occurred by the date that is ninety (90) days from the date of this Agreement.

Section 9.2    Effect of Termination. If this Agreement is terminated, no Party (or any of its Affiliates, directors, officers, representatives or agents) will have any liability to any other Party to this Agreement, except for any liability arising out of any knowing or willful breach of this Agreement (which shall in all circumstances include a Party’s or its Affiliate’s failure to consummate the Closing on the date that the Closing should have occurred pursuant to Section 3.1) prior to such termination and except for the obligations set forth in Section 6.3(c)(i), this Section 9.2 and Article X, which shall survive termination. For the avoidance of doubt, in the event of any breach of Purchaser’s obligation to consummate the Closing, Purchaser’s liability will include any Damages (including any diminution in value of the NGX/Shorcan Companies) suffered by Sellers as a result of the failure of the Closing to occur.

Section 10.1    Payments. Any payments to be made under this Agreement shall be made by wire transfer in Canadian dollars (with amounts denominated in currencies other than Canadian dollars being converted to Canadian dollars in accordance with Section 1.2(d)) on the relevant due date with value on that date in immediately available funds and without deducting costs. Payments to Sellers shall be made to the bank account specified in Section 10.1 of the Sellers Disclosure Letter or such other account as may hereafter be designated by Sellers to Purchaser (such account, the “Sellers’ Bank Account”) and payments to Purchaser shall be made to such bank account hereafter designated by Purchaser to Sellers.

Section 10.2    Notices. All notices, demands, and other communications required or permitted to be given to any Party under this Agreement shall be in writing and any such notice, demand or other communication shall be deemed to have been duly given when delivered by hand, courier or overnight delivery service or, if mailed, two (2) Business Days after deposit in the mail, certified or registered mail, return receipt requested and with first-class postage prepaid, or, if sent by electronic mail, when sent if confirmed by reply electronic mail that is not automated, or, in the case of facsimile notice, when sent and transmission is confirmed, and, regardless of method, addressed to the Party at its address or facsimile number set forth below (or at such other address or facsimile number as the Party shall furnish the other Parties in accordance with this Section 10.2):

Section 10.3    Survival of Representations and Warranties and Covenants.

(a)    The representations and warranties set forth in Article IV and Article V shall terminate effective as of the Closing and shall not survive the Closing for any purpose, and thereafter there shall be no liability on the part of, nor shall any claim (whether predicated on breach of contract, warranty, tortious conduct, common law, statute, strict liability or otherwise) be made by, any Party or any of their respective Affiliates in respect thereof or (except as provided for in the last sentence of Section 10.3(b) regarding covenants and agreements contemplating action (or inaction) following the Closing) otherwise in respect of or in connection with this Agreement or transactions contemplated hereby.

(b)    After the Closing, there shall be no liability on the part of, nor shall any claim be made by, any Party or any of their respective Affiliates in respect of any covenant or agreement to be performed prior to the Closing. The covenants and agreements that contemplate actions (or inaction) to be taken (or not taken) after the Closing shall survive in accordance with their terms.

(c)    For the avoidance of doubt, this Section 10.3 shall not in any way limit Purchaser’s rights to indemnification under Article VIII.

Section 10.4    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed entirely within such State, without regard to the conflict of laws principles of such State (other than §§ 5-1401 and 5-1402 of the New York General Obligations Law).

Section 10.5    Jurisdiction; Venue; Consent to Service of Process.

(a)    Each Party hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of courts of the State of New York, County of New York, including the federal courts located therein, should federal jurisdiction requirements exist for any action arising out of or relating to this Agreement. Each of the Parties consents to the jurisdiction of such courts (and of the appropriate appellate courts) in any such action or proceeding and waives any objection to venue laid therein. In addition, each of the Parties irrevocably and unconditionally waives and agrees not to assert by way of motion, as a defense

or otherwise (i) any claim that it is not subject to the jurisdiction of the above courts, (ii) that its property is exempt or immune from attachment or execution in any such action or proceeding in the above-named courts, (iii) that such action or proceeding is brought in an inconvenient forum, and (iv) that such action or proceeding should be transferred or removed to any court other than one of the above-named courts, or should be stayed by reason of the pendency of some other proceeding in any other court other than one of the above-named courts, or that this Agreement or the subject matter hereof may not be enforced in or by such courts. Each of the Parties hereby agrees not to commence any such action or proceeding other than before one of the above-named courts. Each of the Parties also hereby agrees that any final and non-appealable judgment against a Party in connection with any such action or proceeding shall be conclusive and binding on such Party and that such judgment may be enforced in any court of competent jurisdiction, either within or outside of the United States. A certified or exemplified copy of such award or judgment shall be conclusive evidence of the fact and amount of such award or judgment. The foregoing consent to jurisdiction shall not (A) constitute submission to jurisdiction or general consent to service of process in the State of New York, County of New York, for any purpose except with respect to any action or proceeding resulting from, relating to or arising out of this Agreement or (B) be deemed to confer rights on any Person other than the respective Parties to this Agreement.

(b)    To the extent that any Party has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each of such Seller or Purchaser hereby irrevocably waives such immunity in respect of its obligations with respect to this Agreement.

(c)    Each Party irrevocably consents to service of process in the manner provided for the giving of notices pursuant to Section 10.2 of this Agreement. Nothing in this Section 10.5 shall affect the right of any Party to serve process in any other manner permitted by Law.

Section 10.6    Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the Parties and delivered (by telecopy, electronic delivery or otherwise) to the other Parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Section 10.7    Entire Agreement. This Agreement, together with the Trayport Agreement, the Related Agreements, the Disclosure Letters and the Non-Disclosure Agreement and all annexes and exhibits hereto and thereto, embody the entire agreement of the Parties with respect to the subject matter hereof and supersede all prior agreements with respect thereto.

Section 10.8    Amendment, Modification and Waiver. No amendment to this Agreement shall be effective unless it shall be in writing and signed by each Party. Any failure of a Party to comply with any obligation, covenant, agreement or condition contained in this Agreement may be waived by the Party entitled to the benefits thereof only by a written instrument duly executed and delivered by the Party granting such waiver, but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any prior, subsequent or other failure of compliance.

Section 10.9    Severability. If any provision of this Agreement or the application of any such provision is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement or invalidate or render unenforceable such provision in any other jurisdiction. In the event that any provision hereof would be invalid, illegal or unenforceable, to the extent permitted by applicable Law, the Parties intend that such provision will be construed by modifying or limiting it so as to be valid and enforceable to the maximum extent compatible with, and possible under, applicable Law, and the Parties agree, to the extent lawful and practicable, to use their reasonable efforts to enter into arrangements to reinstate the intended benefits, net of the intended burdens, of any such provision held invalid, illegal or unenforceable.

Section 10.10    Successors and Assigns; No Third-Party Beneficiaries. This Agreement and all its provisions shall be binding solely upon and inure solely to the benefit of the Parties and their respective permitted successors and assigns, each of which such successors and permitted assigns will be deemed to be a party hereto for all purposes hereof. Nothing in this Agreement, whether expressed or implied, will confer on any Person, other than the Parties or their respective permitted successors and assigns, any rights, remedies or Liabilities; provided, that (a) the provisions of Section 6.11 will inure to the benefit of the D&O Indemnified Persons and (b) the provisions of Section 6.11(a) will inure to the benefit of Seller’s Affiliates. No Party may assign its rights or obligations under this Agreement without the prior written consent of the other Parties and any purported assignment without such consent shall be void; provided, that Purchaser may, without the consent of Seller, assign any or all of its rights or obligations hereunder to any of its Subsidiaries that is wholly owned by Purchaser (although no such assignment shall relieve Purchaser of its obligations to Sellers). For the avoidance of doubt, the amalgamation or merger (whether forward or reverse) of any Party to this Agreement with one or more Affiliates of such Party shall not constitute an assignment for purposes of this Section 10.10.

Section 10.11    Publicity. With respect to any information in respect of the transactions contemplated hereby which shall not have been previously issued or disclosed, except as required by Law (including the rules and regulations of any applicable stock exchange), each of Sellers and Purchaser agrees that neither it nor any of its Affiliates will issue a press release or make any other public statement or release any public communication with respect thereto without the prior consultation with the other Party. Purchaser and Sellers agree, to the extent possible and legally permissible, to notify, cooperate and consult with, the other

Party prior to issuing or making any such public statement (and be provided a reasonable opportunity to comment on such public statement).

Section 10.12    WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY LAW, EACH OF THE PARTIES IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM ARISING OUT OF, IN WHOLE OR IN PART, OR RELATING TO THIS AGREEMENT OR ANY OF THE SALE.

Section 10.13    Expenses. Except as otherwise expressly stated in this Agreement, any costs, expenses, or charges incurred by any of the Parties shall be borne by the Party incurring such cost, expense or charge, in each case, whether or not the transactions contemplated hereby shall be consummated. Except as otherwise provided herein, if the Sale is consummated, all costs, expenses and charges incurred and payable by any of the NGX/Shorcan Companies in connection with the negotiation, preparation, execution and delivery of this Agreement and the Related Agreements and the consummation of the Sale will be Transaction Expenses.

Section 10.14    Specific Performance and Other Equitable Relief. The Parties hereby expressly recognize and acknowledge that immediate, extensive and irreparable damage would result, no adequate remedy at law would exist and damages would be difficult to determine if any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached. Each Party further acknowledges that a breach or violation of this Agreement cannot be sufficiently remedied by money damages alone and, accordingly, each Party shall be entitled, without the need to post a bond or other security, in addition to damages and any other remedies provided at law or in equity, to specific performance, injunctive and other equitable relief to enforce or prevent any violation. Each Party agrees not to oppose the granting of such equitable relief, and to waive, and to cause its representatives to waive, any requirement for the securing or posting of any bond in connection with such remedy.

Section 10.15    Guarantee. As a material inducement to Purchaser to enter into this Agreement and in recognition of substantial direct and indirect benefits to Guarantor therefrom, Guarantor hereby absolutely, irrevocably and unconditionally guarantees to Purchaser the due and punctual performance by Sellers of all of Sellers’ obligations and liabilities under or in respect of this Agreement including all of Sellers’ payment obligations hereunder and any obligations or liabilities of Sellers arising from any breach of this Agreement. Guarantor’s liabilities hereunder are absolute, unconditional, irrevocable and continuing irrespective of any modification, amendment or waiver of or any consent to departure from the terms and conditions of this Agreement that may be agreed to by Sellers hereto in accordance with the terms of this Agreement. Guarantor agrees that its obligations hereunder shall not be released or discharged, in whole or in part, or otherwise affected by (a) the failure or delay on the part of Purchaser to assert any claim or demand or to enforce any right or remedy against Sellers or (b) any insolvency, bankruptcy, reorganization or other similar proceeding instituted by or against Sellers. Notwithstanding anything to the contrary contained in this Section 10.15 or otherwise, Purchaser hereby agrees that Guarantor shall have all defenses to its obligations under this

guarantee that would be available to Sellers in respect of this Agreement whether pursuant to the terms of this Agreement or pursuant to any applicable Law in connection therewith.

Section 10.16    Joint and Several Liability of Sellers. Sellers shall be jointly and severally liable for all obligations of each Seller under this Agreement and the Transition Services Agreement.

IN WITNESS WHEREOF, each Party has caused this Stock Purchase Agreement to be duly executed on its behalf as of the day and year first above written.
