Without limiting the generality of the foregoing, Parent and Callco each covenant and agree that it will use commercially reasonable efforts to take all such actions and do all such things as are reasonably necessary or desirable to make such filings and seek such regulatory consents and approvals as are reasonably necessary so that the Parent Shares to be issued or delivered to the Holder by Parent or Callco pursuant to the terms of the Exchangeable Share Provisions and this Agreement may be resold publicly in compliance with the Securities Act and all applicable state securities Laws and applicable provincial and territorial securities Laws in Canada, and will use commercially reasonable efforts to ensure that the Parent Shares will not be subject to any “hold period” resale restriction under National Instrument 45-102 – Resale of Securities of the Canadian securities regulatory authorities. The Holder acknowledges and agrees that Parent Shares issued to it will not be issued in a registered transaction, and may only be resold pursuant to the Registration Statement or in another registered transaction, and only if also qualified or registered under any applicable state Law, or in a transaction exempt from the Securities Act and any applicable state Laws, and any

Parent Shares issued to the Holder may bear, or have associated with them, a legend to such effect.
(b)It shall be a condition precedent to the obligations of the Parent to take any action pursuant to this Section 2.5 that the Holder shall furnish to Parent such information regarding the Holder, the Parent securities held by it, and any other information that is reasonably required to effect the registration of such Holder’s registrable Parent Shares, including the completion of a customary a selling security holder questionnaire.
(c)Notwithstanding anything to the contrary contained herein, Parent may, upon written notice to all holders of registered Parent Shares included in the Registration Statement, suspend the use of the Registration Statement, including any prospectus that forms a part of the Registration Statement, if the Parent determines (i) that it would be required to make disclosure of material information in the Registration Statement that the Parent has a bona fide business purpose for preserving as confidential, (ii) it must amend the Registration Statement to include recast or other historical financial statements or financial information, whether due to a fundamental change (within the meaning of Item 512 of the SEC’s Regulation S-K) or otherwise, or (iii) it must otherwise amend or supplement the Registration Statement or the related prospectus (an “Allowed Delay”); provided, however, that Parent may not suspend the Registration Statement (x) more than two (2) times during any 12-month period, (y) more 30 consecutive days on any single occasion (or 60 days in the event of an amendment pursuant to clause (c)(ii)), and (z) more than 60 days in the aggregate during any 12-month period (or 120 days in the event of an amendment pursuant to clause (c)(ii)). Parent shall use commercially reasonable efforts to minimize the length of Allowed Delays.
(d)Parent shall promptly notify the Holder of: (i) (A) when a Registration Statement, a Prospectus or any prospectus supplement or pre- or post-effective amendment to the Registration Statement is filed, (B) when the SEC notifies Parent whether there will be a “review” of such Registration Statement and whenever the SEC comments in writing on such Registration Statement, and if requested by the Holder, furnish to it a copy of such comments and Parent’s responses thereto, and (C) with respect to the Registration Statement or any post-effective amendment filed by Parent, when the same has become effective; (ii) of any request by the SEC or any other United States Federal or state governmental authority for amendments or supplements to the Registration Statement or Prospectus or for additional information of Parent; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement covering any or all of the Parent Shares or the initiation of any legal proceedings for that purpose; (iv) of the receipt by Parent of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Parent Shares of Parent for sale in any jurisdiction, or the initiation or threatening of any legal

proceeding for such purpose; and (v) of the occurrence of any event that makes any statement made in the Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.
(e)Parent shall use commercially reasonable efforts to cause all Parent Shares relating to the Registration Statement to be listed on any securities exchange, quotation system or market, if any, on which similar securities issued by Parent are then listed or traded.
(f)Upon the occurrence of any event contemplated by Section 2.5(d), Parent shall use commercially reasonable efforts to, as promptly as practicable, prepare a supplement or amendment, including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither the Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.
(g)All reasonable fees and expenses incident to the performance of or compliance with Section 2.5 by Parent (excluding underwriters’ discounts and commissions) shall be borne by Parent whether or not a Registration Statement is filed by Parent or becomes effective and whether or not any Parent Shares are sold pursuant to a Registration Statement.

(b)Each of Parent, Callco and the Company agrees that, for so long as there are any Exchangeable Shares issued and outstanding, it shall use reasonable efforts to take all such actions and to do all such things as are reasonably necessary or desirable to ensure that each Exchangeable Share shall at all times be equal in all respects to the Parent Shares (whether economically, financially or otherwise) into which such Exchangeable Share could be converted, on the basis and as if any such Parent Shares were issued to the Holder and as if the Holder held such Parent Shares.

Such notice shall include a brief description of the automatic exchange of Exchangeable Shares for Parent Shares provided for in this Section 3.2(a).
(b)Immediately prior to the effective date of a Liquidation Event (the “Liquidation Event Effective Date”), each of the then outstanding Exchangeable Shares not owned by Parent or its Subsidiaries shall be automatically exchanged for Exchangeable Share Consideration. To effect such automatic exchange, Parent shall be deemed to have purchased each Exchangeable Share outstanding on the Liquidation Event Effective Date held by the Holder, and the Holder shall be deemed to have sold all, but not less than all, of the Exchangeable Shares held by it at such time to Parent, for an amount per share equal to the Exchangeable Share Price immediately prior to the Liquidation Event Effective Date, which price shall be satisfied in full by Parent delivering to the Holder the Exchangeable Share Consideration representing such Exchangeable Share Price. The Holder shall upon delivery of the Exchangeable Share Consideration cease to have any rights to be paid by the Company any amount in respect of declared and unpaid dividends.
(c)On the Liquidation Event Effective Date, the closing of the transaction of purchase and sale contemplated by the automatic exchange of Exchangeable Shares shall be deemed to have occurred, and the Holder shall be deemed to have transferred to Parent all of the Holder’s right, title and interest in and to such Exchangeable Shares and the Automatic Exchange Rights attaching thereto, except that the Holder shall have the right to receive the Exchangeable Share Consideration payable to the Holder by Parent upon presentation and surrender by the Holder of Exchangeable Share certificates (if any), duly endorsed in blank and accompanied by such instruments of transfer as Parent may reasonably require. Concurrently with such Holder ceasing to hold Exchangeable Shares, the Holder shall be considered and deemed for all purposes to be the holder of the Parent

Shares issued to it as part of the Exchangeable Share Consideration pursuant to the automatic exchange of Exchangeable Shares and Parent shall promptly deliver or cause to be delivered to the Holder evidence that the Parent Shares have been issued to the Holder by Parent pursuant to such automatic exchange.
ARTICLE 4
Article 4 PARENT SUCCESSORS
4.1 Certain Requirements in Respect of Combination, etc.
Subject to Section 7 of the Exchangeable Share Provisions and Article 5 hereof with respect to a Parent Extraordinary Transaction, so long as any Exchangeable Shares not owned by Parent or its Subsidiaries are outstanding, Parent shall not enter into any transaction (whether by way of reorganization, consolidation, arrangement, amalgamation, merger, business combination, transfer, sale, lease or otherwise) whereby all or substantially all of its undertaking, property and assets would become the property of any other person or, in the case of an amalgamation, merger or combination, of the continuing corporation resulting therefrom, provided that it may do so if:
(a)such other person or continuing corporation (the “Parent Successor”) by operation of Law, becomes, without more, bound by the terms and provisions of this Agreement or, if not so bound, executes, prior to or contemporaneously with the consummation of such transaction, an agreement supplemental hereto and such other instruments (if any) as are necessary or advisable to evidence the assumption by the Parent Successor of liability for all moneys payable and property deliverable hereunder and the covenant of such Parent Successor to pay and deliver or cause to be paid and delivered the same and its agreement to observe and perform all the covenants and obligations of Parent under this Agreement; and
(b)such transaction shall be upon such terms and conditions as to preserve and not to impair any of the rights, duties, powers and authorities of the other Parties hereunder or the holders of the Exchangeable Shares.
4.2 Vesting of Powers in Successor
Whenever the conditions of Section 4.1 have been duly observed and performed, the Parties, if required by Section 4.1, shall execute and deliver the supplemental agreement provided for in Section 4.1(a) and thereupon the Parent Successor and such other person that may then be the issuer of the Parent Shares shall possess and from time to time may exercise each and every right and power of Parent under this Agreement in the name of Parent or otherwise and any act or proceeding by any provision of this Agreement required to be done or performed by the board of directors of Parent or any officers of Parent may be done and performed with like force and effect by the directors or officers of such Parent Successor.

4.3 Wholly-Owned Subsidiaries
Nothing herein shall be construed as preventing (a) the amalgamation, merger or combination of any wholly-owned direct or indirect subsidiary of Parent (other than the Company or Callco) with or into Parent, (b) the winding-up, liquidation or dissolution of any wholly-owned direct or indirect subsidiary of Parent (other than the Company or Callco), provided that all of the assets of such subsidiary are transferred to Parent or another wholly-owned direct or indirect subsidiary of Parent, (c) any other distribution of the assets of any wholly-owned direct or indirect subsidiary of Parent (other than the Company or Callco) among the shareholders of such subsidiary for the purpose of winding up its affairs, and (d) any such transactions are expressly permitted by this Article 4.
4.4 Successorship Transaction
Notwithstanding the foregoing provisions of this Article 4, in the event of a Parent Extraordinary Transaction:
(a)in which Parent merges, combines or amalgamates with, or in which all or substantially all of the then outstanding Parent Shares are acquired by, one or more other corporations to which Parent is, immediately before such merger, combination, amalgamation or acquisition, “related” within the meaning of the Tax Act (otherwise than by virtue of a right referred to in paragraph 251(5)(b) thereof);
(b)which does not result in an acceleration of the Redemption Date in accordance with paragraph (iii) of the definition of Redemption Date in the Exchangeable Share Provisions; and
(c)in which all or substantially all of the then outstanding Parent Shares are converted into or exchanged for shares or rights to receive such shares (the “Other Shares”) of another corporation (the “Other Corporation”) that, immediately after such Parent Extraordinary Transaction, owns or controls, directly or indirectly, Parent;
then all references herein to “Parent” shall thereafter be deemed to be references to “Other Corporation” and all references herein to “Parent Shares” shall thereafter be and be deemed to be references to “Other Shares” (with appropriate adjustments if any, as are required to result in a holder of Exchangeable Shares on the exchange, redemption or retraction of such shares pursuant to the Exchangeable Share Provisions or this Agreement including the exchange of such shares pursuant to this Agreement immediately subsequent to the Parent Extraordinary Transaction being entitled to receive that number of Other Shares equal to the number of Other Shares such holder of Exchangeable Shares would have received if the exchange, redemption or retraction of such shares pursuant to the Exchangeable Share Provisions or this Agreement including the exchange of such shares pursuant to this Agreement had occurred immediately prior to the Parent Extraordinary Transaction and the Parent Extraordinary Transaction was

completed) but subject to subsequent adjustments to reflect any subsequent changes in the share capital of the issuer of the Other Shares, including without limitation, any subdivision, consolidation or reduction of share capital, without any need to amend the terms and conditions of the Exchangeable Shares and without any further action required.
ARTICLE 5
Article 5 CERTAIN RIGHTS OF PARENT AND CALLCO TO ACQUIRE EXCHANGEABLE SHARES
5.1 Liquidation Call Right
In addition to the rights contained in the Exchangeable Share Provisions, Parent, Callco and the holders of the Exchangeable Shares shall have the following rights and obligations in respect of the Exchangeable Shares:
(a)Subject to the proviso in Section 5.1(b) that Callco shall only be entitled to exercise the Liquidation Call Right with respect to those Exchangeable Shares, if any, in respect of which Parent has not exercised the Liquidation Call Right, Parent and Callco shall each have the overriding right (the “Liquidation Call Right”), in the event of and notwithstanding the proposed liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, or any other distribution of the assets of the Company among its shareholders for the purpose of winding up its affairs, to purchase from all but not less than all of the holders of the Exchangeable Shares (other than any holder of Exchangeable Shares which is Parent or any of its Subsidiaries) on the Liquidation Date all but not less than all of the Exchangeable Shares held by each such holder upon payment by Parent or Callco, as the case may be, to each such holder of an amount per share equal to the Exchangeable Share Price (payable in the form of the Exchangeable Share Consideration) applicable on the last Business Day prior to the Liquidation Date (the “Liquidation Call Purchase Price”) in accordance with Sections 5.1(c) and (d). In the event of the exercise of the Liquidation Call Right by Parent or Callco, as the case may be, each such holder of Exchangeable Shares (other than Parent and its Subsidiaries) shall be obligated to sell all of the Exchangeable Shares held by the holder to Parent or Callco, as the case may be, on the Liquidation Date upon payment by Parent or Callco, as the case may be, to such holder of the Liquidation Call Purchase Price (payable in the form of Exchangeable Share Consideration) for each such share, and the Company shall have no obligation to pay any Liquidation Amount to the holders of such shares so purchased.
(b)Callco shall only be entitled to exercise the Liquidation Call Right with respect to those Exchangeable Shares, if any, in respect of which Parent has not exercised the Liquidation Call Right. To exercise the Liquidation Call Right, Parent or Callco, as the case may be, must notify the Company of its intention to exercise such right (i) in the case of a voluntary liquidation, dissolution or winding-up of the Company or any other voluntary distribution of the assets of the Company among its shareholders for the purpose of winding up its affairs, at fifteen (15)

Business Days before the Liquidation Date, or (ii) in the case of an involuntary liquidation, dissolution or winding-up of the Company or any other involuntary distribution of the assets of the Company among its shareholders for the purpose of winding up its affairs, at least five (5) Business Days before the Liquidation Date. The Company will notify the holders of the Exchangeable Shares as to whether or not Parent and/or Callco has exercised the Liquidation Call Right forthwith after the expiry of the period during which Parent or Callco may exercise the Liquidation Call Right, to ensure each such holder shall be able to exercise its Liquidation Put Right in accordance with Section 5.1(d). If Parent and/or Callco exercises the Liquidation Call Right, then on the Liquidation Date, Parent and/or Callco, as the case may be, will purchase and the holders of the Exchangeable Shares (other than any holder of Exchangeable Shares which is Parent or any of its Subsidiaries) will sell, all of the Exchangeable Shares held by such holders on such date for a price per share equal to the Liquidation Call Purchase Price (payable in the form of Exchangeable Share Consideration).
(c)For the purposes of completing the purchase and sale of the Exchangeable Shares pursuant to the exercise of the Liquidation Call Right, Parent or Callco, as the case may be, shall deliver or cause to be delivered to each holder of Exchangeable Shares (other than the Parent and its Subsidiaries), at the address of such holder recorded in the securities register of the Company or holding for pick-up by such holder at the registered office of the Company, on or before the Liquidation Date, the Exchangeable Share Consideration representing the Liquidation Call Purchase Price to which such holder is entitled, less any amounts withheld pursuant to Section 6.1, upon presentation and surrender of a certificate or certificates representing such Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under the Act and the articles of the Company, as applicable, and such additional documents, instruments and payments as the Company may reasonably require, at the registered office of the Company. Provided that such Exchangeable Share Consideration has been so delivered, the holders of the Exchangeable Shares (other than Parent and its Subsidiaries) shall cease to be holders of the Exchangeable Shares on and after the Liquidation Date and, from and after such date, shall not be entitled to exercise any of the rights of holders in respect thereof other than the right to receive their proportionate part of the aggregate Liquidation Call Purchase Price, without interest, upon presentation and surrender by the holder of certificates representing the Exchangeable Shares held by such holder and the holder shall on and after the Liquidation Date be considered and deemed for all purposes to be the holder of the Parent Shares which such holder is entitled to receive.
(d)If neither Parent nor Callco exercises the Liquidation Call Right in the manner and timing described above, each holder of Exchangeable Shares will, at the holder’s discretion, be entitled to demand (by way of notice given to the Company or the Parent) that the Parent exercise (or cause Callco to exercise) the Liquidation

Call Right in respect of the shares covered by the notice, it being understood that any notice right or other notification requirement set out in this Section 5.1 shall not apply in such circumstances (the “Liquidation Put Right”).
5.2 Retraction Call Right
In addition to the rights contained in the Exchangeable Share Provisions, Parent and Callco shall have the following rights and obligations in respect of the Exchangeable Shares:
(a)In the event that a holder of Exchangeable Shares delivers a Retraction Request pursuant to Section 6(a) of the Exchangeable Share Provisions, and subject to the limitations set forth in Section 6(b) of the Exchangeable Share Provisions that Callco shall only be entitled to exercise the Retraction Call Right with respect to those Exchangeable Shares, if any, in respect of which Parent has not exercised the Retraction Call Right, and notwithstanding the proposed redemption of the Exchangeable Shares by the Company pursuant to the Exchangeable Share Provisions, Parent and Callco shall each have an overriding right (the “Retraction Call Right”) to purchase from such holder on the Retraction Date all but not less than all of the Retracted Shares held by such holder on payment by Parent or Callco, as the case may be, of an amount per share equal to the Exchangeable Share Price (payable in the form of the Exchangeable Share Consideration) applicable on the last Business Day prior to the Retraction Date (the “Retraction Call Right Purchase Price”), which price shall be satisfied in full by Parent or Callco, as the case may be, delivering or causing to be delivered to such holder the Exchangeable Share Consideration in satisfaction of the Retraction Call Right Purchase Price in accordance with Sections 5.2(c) and (e). Upon the exercise of the Retraction Call Right in respect of Retracted Shares, the holder of such Retracted Shares shall be obligated to sell all of such Retracted Shares to Parent or Callco, as the case may be, on the Retraction Date on payment by Parent or Callco, as the case may be, of the aggregate Retraction Call Right Purchase Price in respect of such Retracted Shares as set forth in this Section 5.2(a).
(b)Callco shall only be entitled to exercise its Retraction Call Right with respect to those holders of Retracted Shares, if any, in respect of which Parent has not exercised its Retraction Call Right. To exercise its Retraction Call Right, Parent or Callco, as the case may be, must notify the Company in writing of its intention to exercise the Retraction Call Right (a “Retraction Call Notice”) within five (5) Business Days after the Company notifies Callco or Parent of its right to do so. If neither Parent nor Callco so notifies the Company within such five (5) Business Day period, the Company shall notify the holder as soon as possible thereafter that neither Callco nor Parent will exercise the Retraction Call Right, to ensure each such holder shall be able to exercise its Retraction Put Right in accordance with Section 5.2(e). If one or both of Parent and Callco delivers a Retraction Call Notice within such five (5) Business Day period and duly exercises its Retraction Call Right in accordance with this Section 5.2(b), or the holder has exercised a Retraction Put Right in relation to the Retracted Shares, the obligation of the

Company to redeem shall terminate and, provided that the Retraction Request is not revoked by the holder of such Retracted Shares in the manner specified in Section 6(d) of the Exchangeable Share Provisions, Parent or Callco, as the case may be, shall purchase from such holder and such holder shall sell to Parent or Callco, as the case may be, on the Retraction Date the Retracted Shares for an amount per share equal to the Retraction Call Right Purchase Price (payable in the form of the Exchangeable Share Consideration). Provided that the aggregate Retraction Call Right Purchase Price has been so deposited as provided in Section 5.2(c), the closing of the purchase and sale of the Retracted Shares pursuant to the Retraction Call Right shall be deemed to have occurred as at the close of business on the Retraction Date and, for greater certainty, no redemption by the Company of such Retracted Shares shall take place on the Retraction Date.
(c)For the purpose of completing a purchase of Retracted Shares pursuant to the exercise of the Retraction Call Right, Parent or Callco, as the case may be, shall deliver or cause to be delivered to the holder of such Retracted Shares, at the address of the holder recorded in the securities register of the Company for the Exchangeable Shares or at the address specified in the holder’s Retraction Request or by holding for pick-up by the holder at the registered office of the Company, the Exchangeable Share Consideration representing the Retraction Call Right Purchase Price to which such holder is entitled and such delivery of Exchangeable Share Consideration on behalf of Parent or Callco, as the case may be, shall be deemed to be payment of and shall satisfy and discharge all liability for the Retraction Call Right Purchase Price, unless any cheque comprising part of such Exchangeable Share Consideration is not paid on due presentation.
(d)On and after the close of business on the Retraction Date, the holder of the Retracted Shares shall cease to be a holder of such Retracted Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive the aggregate Retraction Call Right Purchase Price in respect thereof, unless payment of the aggregate Retraction Call Right Purchase Price payable to such holder shall not be made upon presentation and surrender of share certificates and other required documents in accordance with the foregoing provisions, in which case the rights of such holder shall remain unaffected until such aggregate Retraction Call Right Purchase Price has been paid in the manner hereinbefore provided. On and after the close of business on the Retraction Date, provided that presentation and surrender of certificates and payment of such aggregate Retraction Call Right Purchase Price has been made in accordance with the foregoing provisions, the holder of the Retracted Shares so purchased by Parent or Callco, as the case may be, shall thereafter be considered and deemed for all purposes to be a holder of the Parent Shares delivered to such holder.
(e)If neither Parent nor Callco exercises the Retraction Call Right in the manner and timing described therein, each holder of Exchangeable Shares will, at the holder’s discretion, be entitled to demand (by way of notice given to the Company or the

Parent) that the Parent exercise (or cause Callco to exercise), the Retraction Call Right in respect of the shares covered by the notice, it being understood that any notice right or other notification requirement set out in this Section 5.2 shall not apply in such circumstances (the “Retraction Put Right”).
5.3 Redemption Call Right
In addition to the rights contained in the Exchangeable Share Provisions, Parent and Callco shall have the following rights and obligations in respect of the Exchangeable Shares:
(a)Subject to the proviso in Section 5.3(b) that Callco shall only be entitled to exercise the Redemption Call Right with respect to those Exchangeable Shares, if any, in respect of which Parent has not exercised the Redemption Call Right, and notwithstanding the proposed redemption of the Exchangeable Shares by the Company pursuant to the Exchangeable Share Provisions, Parent and Callco shall each have the overriding right (the “Redemption Call Right”) to purchase from all but not less than all of the holders of the Exchangeable Shares (other than any holder of Exchangeable Shares which is Parent or any of its Subsidiaries) on the Redemption Date all but not less than all of the Exchangeable Shares held by each such holder upon payment by Parent or Callco, as the case may be, to each such holder of the Exchangeable Share Price (payable in the form of the Exchangeable Share Consideration) applicable on the last Business Day prior to the Redemption Date (the “Redemption Call Purchase Price”) in accordance with Sections 5.3(c) and (d). In the event of the exercise of the Redemption Call Right by Parent or Callco, as the case may be, each such holder of Exchangeable Shares shall be obligated to sell all of the Exchangeable Shares held by the holder to Parent or Callco, as the case may be, on the Redemption Date upon payment by Parent or Callco, as the case may be, to such holder of the Redemption Call Purchase Price (payable in the form of Exchangeable Share Consideration), and the Company shall have no obligation to redeem, or to pay the redemption price otherwise payable by the Company in respect of the Exchangeable Shares so purchased.
(b)Callco shall only be entitled to exercise the Redemption Call Right with respect to those Exchangeable Shares, if any, in respect of which Parent has not exercised the Redemption Call Right. To exercise the Redemption Call Right, Parent or Callco, as the case may be, must notify the Company of its intention to exercise such right (i) in the case of a redemption occurring in connection with a Parent Extraordinary Transaction, as soon as possible and in any event within a reasonable period prior to the Redemption Date in order to ensure holders of Exchangeable Shares shall be able to exercise their Redemption Put Rights in accordance with Section 5.3(d), and (ii) in any other case, at least fifteen (15) Business Days before the Redemption Date. The Company will notify the holders of the Exchangeable Shares as to whether or not Parent and/or Callco has exercised the Redemption Call Right as soon as possible in the case of the foregoing (i) and forthwith after the expiry of the period during which Parent or

Callco may exercise the Redemption Call Right in the case of the foregoing (ii). If Parent and/or Callco exercises the Redemption Call Right, such notice from Parent and/or Callco to the Company shall set out the particulars of the Redemption Call Right and the formula for determining the Redemption Call Right Price. If Parent and/or Callco exercises the Redemption Call Right, Parent and/or Callco, as the case may be, will purchase and the holders of the Exchangeable Shares (other than any holder of Exchangeable Shares which is Parent or any of its Subsidiaries) will sell, on the Redemption Date, all of the Exchangeable Shares held by such holders on such date for a price per share equal to the Redemption Call Purchase Price (payable in the form of Exchangeable Share Consideration).
(c)For the purposes of completing the purchase and sale of the Exchangeable Shares pursuant to the exercise of the Redemption Call Right, Parent or Callco, as the case may be, shall deliver or cause to be delivered to each holder of Exchangeable Shares (other than the Parent and its Subsidiaries), at the address of such holder recorded in the securities register of the Company or holding for pick-up by such holder at the registered office of the Company, on or before the Redemption Date, the Exchangeable Share Consideration representing the aggregate Redemption Call Purchase Price to which such holder is entitled, less any amounts withheld pursuant to Section 6.1, upon presentation and surrender of a certificate or certificates representing such Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under the Act and the articles of the Company, as applicable, and such additional documents, instruments and payments as the Company may reasonably require, at the registered office of the Company. Provided that such Exchangeable Share Consideration has been so delivered, the holders of the Exchangeable Shares (other than Parent and its Subsidiaries) shall cease to be holders of the Exchangeable Shares on and after the Redemption Date and, from and after such date, shall not be entitled to exercise any of the rights of holders in respect thereof other than the right to receive their proportionate part of the aggregate Redemption Call Purchase Price, without interest, upon presentation and surrender by the holder of certificates representing the Exchangeable Shares held by such holder and the holder shall on and after the Redemption Date be considered and deemed for all purposes to be the holder of the Parent Shares which such holder is entitled to receive.
(d)If neither Parent nor Callco exercises the Redemption Call Right in the manner and timing described above, each holder of Exchangeable Shares will, at the holder’s discretion, be entitled to demand (by way of notice given to the Company or the Parent) that the Parent exercise (or cause Callco to exercise), the Redemption Call Right in respect of the shares covered by the notice, it being understood that any notice right or other notification requirement set out in this Section 5.3 shall not apply in such circumstances (the “Redemption Put Right”).

ARTICLE 6
Article 6 TAX MATTERS
6.1 Right to Withhold
(a)Each of Parent, the Company, Callco and any other Person that has any withholding obligation with respect to any amount paid, deemed paid or otherwise deliverable to any holder of Exchangeable Shares (any such Person, an “Other Withholding Agent”) shall be entitled to deduct and withhold or direct Parent, the Company, Callco, or any Other Withholding Agent to deduct and withhold on their behalf, from any amount or consideration paid, deemed paid or otherwise deliverable to any holder of Exchangeable Shares such amounts as are required to be deducted or withheld with respect to such payment or deemed payment under the Tax Act or United States Tax Laws or any provision of federal, provincial, territorial, state, local, foreign or other Tax Law, in each case, as amended or succeeded. Parent, the Company, Callco, or any Other Withholding Agent may act and rely on the advice of counsel with respect to such matters. To the extent that amounts are so deducted or withheld, such deducted or withheld amounts shall be treated for all purposes as having been paid to the holder of the Exchangeable Shares to whom such amounts would otherwise have been paid or deemed paid and such deducted or withheld amounts shall be timely remitted to the appropriate Governmental Authority as required by applicable Law.
(b)To the extent that the amount so required to be deducted or withheld from any payment or deemed payment to a holder exceeds the cash portion of the amount or consideration otherwise payable to the holder (such difference, a “Withholding Shortfall”), the holder shall deliver a cash payment to the Parent, the Company, Callco or the Other Withholding Agent, as applicable, equal to such Withholding Shortfall (the “Shortfall Cash Payment”). If a holder fails to deliver a Shortfall Cash Payment, Parent, the Company, Callco, and any Other Withholding Agent are hereby authorized to (A) (i) sell or otherwise dispose of, or direct Parent, the Company, Callco or any Other Withholding Agent to sell or otherwise dispose of, on their own account or through a broker (the “Broker”) and on behalf of the relevant holder or (ii) require such holder to irrevocably direct the sale through a Broker and irrevocably direct the Broker pay the proceeds of such sale to Parent, the Company, Callco or any Other Withholding Agent, as appropriate (and, in the absence of such irrevocable direction, the holder shall be deemed to have provided such irrevocable direction), such portion of the amount or consideration as is necessary to provide sufficient funds (after deducting commissions payable to the Broker and other costs and expenses) to Parent, the Company, Callco or any Other Withholding Agent, as the case may be, to enable it to comply with such deduction or withholding requirement and Parent, the Company, Callco or any Other Withholding Agent, as the case may be, shall notify the holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale or (B) require such holder to deliver a Retraction Request for a number of Exchangeable

Shares that would entitle such holder to net proceeds greater than or equal to the Withholding Shortfall and withhold the Withholding Shortfall from such net proceeds and remit to such holder any unapplied balance of the net proceeds. None of Parent, the Company, Callco, the Broker or any Other Withholding Agent, as applicable, will be liable for any loss arising out of any sale or other disposal of such consideration, including any loss relating to the manner or timing of such sale or other disposal, the prices at which the consideration is sold or otherwise disposed of or otherwise.
(c)If any of Parent, the Company, Callco, and any Other Withholding Agent intends to deduct or withhold any amount from any payment to be made pursuant to the terms of this Agreement, such Person shall use commercially reasonable efforts to: (a) provide at least ten (10) Business Days’ notice in writing to the holder in respect of which such withholding may be required and include the reasonable legal basis for such withholding and (b) provide such holder with a reasonable opportunity to provide forms or other evidence that would reduce or eliminate any such amounts otherwise required to be deducted and withheld, including relief that may be available under the Income Tax Treaty. In order to substantiate the foregoing entitlement, holders of Exchangeable Shares agree to provide, and update as necessary, properly executed Form W-8s (e.g., Form W-8BEN-E, W-8BEN, etc.), as applicable. Each of Parent, the Company, Callco, the Broker or any Other Withholding Agent, as applicable, shall take into account the Form W-8s provided by the holders of Exchangeable Shares, and shall in reliance on such forms, apply the reduced withholding rate on dividends under Art. X(2)(a) or (b) of the Income Tax Treaty as applicable.
(d)As soon as practicable after any payment of withheld amounts to the appropriate tax authority pursuant to this Section 6.1, the Holder shall be provided with evidence of such payment reasonably satisfactory to the Holder.
ARTICLE 7
Article 7 GENERAL
7.1 Term
This Agreement shall come into force and be effective as of the date hereof and shall terminate and be of no further force and effect at such time as no Exchangeable Shares (or securities or rights convertible into or exchangeable for or carrying rights to acquire Exchangeable Shares) are held by any person other than Parent and any of its Subsidiaries.
7.2 Changes in Capital of Parent and the Company
Notwithstanding the provisions of Section 7.4, at all times after the occurrence of any event contemplated pursuant to Section 2.6 and Section 2.7 or otherwise, as a result of which either Parent Shares or the Exchangeable Shares or both are in any way changed, this Agreement shall forthwith be amended and modified as necessary in order that it shall apply with full force

and effect, mutatis mutandis, to all new securities into which Parent Shares or the Exchangeable Shares or both are so changed and the parties hereto shall execute and deliver an agreement in writing giving effect to and evidencing such necessary amendments and modifications.
7.3 Severability

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner so that the transactions contemplated hereby are fulfilled to the extent possible.
7.4 Amendments, Modifications

7.5 Ministerial Amendments
Notwithstanding the provisions of Section 7.4, the Parties may in writing at any time and from time to time, without the approval of any other holder of Exchangeable Shares, amend or modify this Agreement (approval of the Holder not to be unreasonably withheld or delayed) for the purposes of:
(a)adding to the covenants of any or all of the parties hereto, provided that such additions will not be prejudicial to the rights or interests of the Holder;
(b)evidencing the succession of Parent Successors and the covenants of and obligations assumed by each such Parent Successor in accordance with the provisions of Article 4;
(c)making such amendments or modifications not inconsistent with this Agreement as may be necessary or desirable with respect to matters or questions arising hereunder which, it may be expedient to make, provided that such amendments or modifications will not be prejudicial to the rights or interests of the Holder; or
(d)making such changes or corrections hereto which, on the advice of counsel to Parent, Callco and the Company, are required for the purpose of curing or correcting any ambiguity or defect or inconsistent provision or clerical omission

or mistake or manifest error contained herein, provided that such changes or corrections will not be prejudicial to the rights or interests of the Holder.
