The funds used to make such loans and acquire beneficial ownership of the shares reported herein were composed of the investment capital of the applicable Funds.

The information set forth in Items 3 and 6 of this Statement is hereby incorporated by reference into this Item 4.

The Reporting Persons acquired the securities reported herein for investment purposes and intend to review their investments in the Company on a continuing basis. Depending on various factors, including but not limited to the Company’s financial position and strategic direction, price levels of the Common Stock, conditions in the securities markets, various laws and regulations applicable to the Company and companies in its industry and the Reporting Persons’ ownership in the Company and position as lender to the Company, and general economic and industry conditions, the Reporting Persons may in the future take actions with respect to their investment in the Company as they deem appropriate, including changing their current intentions, with respect to any or all matters required to be disclosed herein. Without limiting the foregoing, and subject to any applicable limitations described in Item 6 below, the Reporting Persons may, from time to time, acquire or cause affiliates to acquire additional shares of Common Stock or other securities of the Company (including any combination or derivative thereof), dispose, or cause affiliates to dispose, of some or all of their Common Stock or other securities of the Company or continue to hold, or cause affiliates to hold, Common Stock or other securities of the Company.

In addition, the Reporting Persons have had and intend to continue having discussions, from time to time, with management and the board of directors of the Company, and may engage with other stockholders or securityholders of the Company and other relevant parties, or take other actions concerning, the Company’s business, lines of business, operations, strategy, previously announced restructuring, plans and prospects; any extraordinary corporate transactions (including, but not limited to, a merger, reorganization or liquidation); sales of a material amount of assets or divestitures; a change in the board of directors or management; a material change in the capitalization or dividend policies; other material changes in the Company’s business, lines of business, or corporate structure; or similar actions.

Except as set forth herein, or as would occur upon completion of any of the matters discussed herein, the Reporting Persons have no present plans, proposals or intentions which would result in or relate to any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Although the foregoing reflects activities presently contemplated by the Reporting Persons and each other individuals named in Item 2 with respect to the Company, the foregoing is subject to change at any time.

(a)-(b) The information contained on the cover pages of this Schedule 13D is incorporated herein by reference.

The Reporting Persons beneficially own in the aggregate 67,966,548 shares of Common Stock, which represents approximately 63.4% of the outstanding shares of Common Stock. All calculations of percentage ownership in this Schedule 13D are based on 107,205,172 shares of Common Stock outstanding.

Madryn, as the investment manager for each of the Funds, and the Advisors, as the general partners for each of the Funds, may be deemed to have the shared power to direct the voting and disposition of shares of Common Stock beneficially owned by the Funds and, consequently, Madryn and the Advisors may be deemed to possess indirect beneficial ownership of such shares. Madryn and the Advisors disclaim beneficial ownership of such shares for all other purposes.

The responses of the Reporting Persons to rows 7, 8, 9, 10, 11 and 13 on the cover pages of this Statement are incorporated herein by reference.

To the knowledge of the Reporting Persons, none of the Covered Persons directly owns any shares of Common Stock; provided, however, that because of each Covered Persons’ status as a director, executive officer, manager, member or partner of a Reporting Person, a Covered Person may be deemed to be the beneficial owner of the shares of Common Stock beneficially owned by such Reporting Person. Except to the extent of their pecuniary interest, each of the Covered Persons disclaims beneficial ownership of the shares of the Common Stock reported herein and the filing of this Schedule 13D shall not be construed as an admission that any such Covered Person is the beneficial owner of any securities covered by this statement.

(c) Except as described herein, none of the Reporting Persons or, to their knowledge, none of the Covered Persons, has had any transactions in the Common Stock during the past 60 days.

(d) Except as set forth herein, to the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any shares of Common Stock.

Certificate No. 1

THIS IS TO CERTIFY that Madryn Health Partners II, LP and its transferees, successors and assigns (the “Holder”) shall have the right (but not the obligation) to convert the Outstanding Amount of Loans owing to the Holder under the Credit Agreement, up to the Maximum Conversion Amount then available, into common shares, without par value (the “Common Shares”) in the capital of Greenbrook TMS Inc., a corporation incorporated under the laws of the Province of Ontario (the “Company”), at the initial conversion price of $1.90 per Common Share (the “Conversion Price”), at any time after the date of issuance listed above (the “Commencement Date”) and expiring on the Expiration Date. This Twelfth Amended and Restated Common Share Conversion Instrument (this “Instrument”) is issued subject to the Organization Documents of the Company and under and pursuant to that certain Credit Agreement, dated as of July 14, 2022, by and among the Company, the Holder, and the other parties thereto (as amended, modified or supplemented from time to time, the “Credit Agreement”). Capitalized terms used herein shall have the meanings ascribed to such terms in Section 13 hereof unless otherwise defined herein.

This Instrument amends, restates and replaces in its entirety that certain Eleventh Amended and Restated Common Share Conversion Instrument dated as of December 19, 2023, issued by the Company to the Holder.

SECTION 1. The Instrument; Transfer and Exchange.

(a) The Instrument. This Instrument and the rights and privileges of the Holder hereunder may be exercised in whole or in part as provided herein and, as more fully set forth in Section 1(b) and Section 7 hereof, may, subject to applicable securities laws and the terms of this Instrument, be transferred by the Holder to any other Person or Persons who meet the requirements set forth herein at any time or from time to time, in whole or in part.

(b) Transfer and Exchanges. The Company shall initially record this Instrument in a register maintained by the Company for that purpose and subject to Section 7 hereof, from time to time thereafter shall reflect the transfer of this Instrument on such register when surrendered for transfer in accordance with the terms hereof and properly endorsed, accompanied by appropriate instructions, and further accompanied by payment in cash or by check, bank draft or money order payable to the order of the Company, in United States currency, of

an amount equal to any stamp or other tax or governmental charge or fee required to be paid in connection with the transfer thereof. Upon any such transfer, a new conversion instrument or conversion instruments shall be issued to and in the name of the transferee and the Holder (in the event this Instrument is only partially transferred or in connection with any concurrent partial transfer and partial exercise) and the surrendered conversion instrument shall be canceled and the Company shall update the register accordingly. This Instrument may be exchanged at the option of the Holder, when surrendered at the Principal Office of the Company, for another conversion instrument or other conversion instruments of like tenor and representing in the aggregate the right to convert a like amount of the Outstanding Amount of Loans owing to the Holder under the Credit Agreement, up to the Maximum Conversion Amount then available, into a like number of Common Shares at the Conversion Price (as such number may be adjusted upon adjustment of the Conversion Price as provided in Section 5).

SECTION 2. Exercise.

(a) Right to Exercise. At any time after the Commencement Date and on or before the Expiration Date, the Holder, in accordance with applicable securities laws and the terms hereof, shall be entitled to exercise the conversion rights under this Instrument, in whole at any time or in part from time to time, by delivering this Instrument to the Company during normal business hours on any Business Day at the Company’s Principal Office, together with the Notice of Conversion (with a copy to the Administrative Agent), in the form attached hereto as Exhibit A and made a part hereof (the “Notice of Conversion”), duly executed. The Holder shall not be required to deliver the original of this Instrument in order to effect an exercise hereunder. Subject to Section 2(c), the aggregate number of Conversion Shares to be subscribed for by the Holder pursuant to the applicable Notice of Conversion shall be equal to the amount calculated by dividing (i) the Aggregate Conversion Amount by (ii) the Conversion Price then in effect.

(b) Conversion of the Aggregate Conversion Amount. For any exercise, in whole or in part, of the conversion rights under this Instrument, payment of the Aggregate Conversion Amount shall be made to the Company by (i) automatically reducing the Outstanding Amount of the Loans owing to the Holder under the Credit Agreement by an amount equal to the Aggregate Conversion Amount or (ii) a Net Exercise as provided in Section 2(c). Other than in the case of a Net Exercise in accordance with Section 2(c), simultaneously with the allotment and issuance of Conversion Shares, or the payment of the applicable Cash Settlement Amount, as the case may be, pursuant to Section 2(e), the Outstanding Amount of the Loans in an amount equal to the Aggregate Conversion Amount shall be deemed repaid under the Credit Agreement in accordance with Section 2.14 thereof. Following any exercise, in whole or in part, of the conversion rights under this Instrument, the Maximum Conversion Amount available for any subsequent exercise of the conversion rights under this Instrument shall be reduced by the Aggregate Conversion Amount paid by the Holder in connection with such exercise.

(c) Net Exercise. The Holder shall have the right to pay all or a portion of the Aggregate Conversion Amount by making a net exercise (“Net Exercise”), in which case the portion of the Aggregate Conversion Amount to be so paid shall be paid by reducing the number of Conversion Shares otherwise issuable pursuant to the Notice of Exercise by an amount equal to (i) the Aggregate Conversion Amount to be so paid, divided by (ii) the Fair Market Value Per Common Share. For the avoidance of doubt, in the case of a Net Exercise by the Holder, no amount of the Outstanding Amount of the Loans owing to the Holder under the Credit Agreement shall be reduced or deemed repaid.

(d) Cash Settlement.

(i) Notwithstanding any other provision of this Instrument, if, following the exercise of the conversion rights under this Instrument, (A) the applicable rules of the Toronto Stock Exchange (“TSX”) or The Nasdaq Stock Market LLC (“Nasdaq”) require approval by TSX or Nasdaq, as applicable, for any allotment or issuance of any number of Conversion Shares by the Company with respect to all or any portion of the Aggregate Conversion Amount, and the Company is unable to obtain such approval by using commercially reasonable efforts, (B) on or prior to the Share Delivery Date, the Company makes a written request to satisfy its obligations under this Instrument by means other than such allotment and

2

issuance of such number of Conversion Shares, and the Holder, in its sole and absolute discretion, accepts such request, or (C) the Company fails for any reason to allot and issue the applicable number of Conversion Shares with respect to all or any portion of the Aggregate Conversion Amount on or prior to the Share Delivery Date, and the Holder, in its sole and absolute discretion, elects to require the Company to satisfy its obligations under this Instrument by means other than such allotment and issuance of such applicable number of Conversion Shares (any such portion of the Aggregate Conversion Amount referred to in Section 2(d)(i)(A), (B) or (C), the “Non-Share Settled Portion”), then, in each case, the Company shall, in lieu of allotting and issuing to the Holder the applicable number of Conversion Shares with respect to the Non-Share Settled Portion, pay the applicable Cash Settlement Amount to the Holder for such Non-Share Settled Portion. Notwithstanding the foregoing, in the case of any Automatic Exercise pursuant to Section 2(i), the Company shall not be permitted to satisfy its obligations under this Instrument by means of payment of the applicable Cash Settlement Amount to the Holder, other than payment of the Cash Settlement Amount for the Non-Share Settled Portion referred to in Section 2(d)(i)(A).

(ii) The cash settlement amount (the “Cash Settlement Amount”) for any Non-Share Settled Portion shall be calculated as of the date of exercise of this Instrument and shall be equal to the product of (A) the Fair Market Value Per Common Share, multiplied by (B) the number of Conversion Shares which would, but for the occurrence of any event referred to in Section 2(d)(i)(A), (B) or (C), have been issuable to the Holder upon exercise of the conversion rights under this Instrument with respect to such Non-Share Settled Portion.

(iii) The Company shall be required to pay any Cash Settlement Amount to the Holder on or before the following applicable date (each, a “Cash Settlement Date”): (A) if such payment is required under Section 2(d)(i)(A), the Share Delivery Date; (B) if such payment is required under Section 2(d)(i)(B), the fifth (5^th) Business Day following the date of the Holder’s acceptance of the written request of the Company referred to in Section 2(d)(i)(B); or (C) if such payment is required under Section 2(d)(i)(C), the third (3^rd) Business Day following the date of the Holder’s election referred to Section 2(d)(i)(C). Notwithstanding the foregoing, the Cash Settlement Date (other than the Cash Settlement Date in connection with any Cash Settlement Amount to be paid upon any Automatic Exercise) shall be extended by up to five (5) Business Days in the event the Company is required to adjust the Conversion Price in accordance with Section 5.

(iv) The Company covenants and agrees that, after the date of issuance set forth above, it shall not, without the prior written consent of the Holder, enter into or agree to become subject to specific or direct contractual term, condition, provision or agreement that would specifically prohibit the performance of the Company’s obligations to pay the applicable Cash Settlement Amount under this Section 2(d).

(e) Issuance of Conversion Shares or Payment of Cash Settlement Amount Upon Exercise. Upon (x) receipt by the Company of a Notice of Conversion at its Principal Office in proper form for exercise or (y) any Net Exercise as provided in Section 2(c) or any Automatic Exercise as provided in Section 2(i), the Company shall:

(i) allot and issue to the Holder, without delay and in any case on or prior to the Share Delivery Date, the number of Conversion Shares specified in the Notice of Conversion as set forth in Exhibit B hereto; or

(ii) if applicable, pay to the Holder the applicable Cash Settlement Amount in accordance with Section 2(d),

and, in each case, simultaneously deliver to the Holder, without duplication, all Distributed Property that the Holder is entitled to receive pursuant to Section 5(a)(ii).

3

(f) Fractional Shares. If any fraction of a Conversion Share would be deliverable upon an exercise of this Instrument, the Company may, in lieu of delivering such fraction of a Conversion Share, make a cash payment to the Holder in an amount equal to the same fraction of the Fair Market Value Per Common Share determined as of the date of exercise of this Instrument.

(g) Partial Exercise. In the event that the Holder exercises this Instrument in part from time to time, there shall be no restriction on the number of times the Holder may exercise its conversion rights under this Instrument to subscribe for Conversion Shares or the minimum number of Conversion Shares that the Holder shall be required to subscribe for upon any partial exercise of its conversion rights under this Instrument. Upon any partial exercise of this Instrument, the Company shall issue and deliver to the Holder a new conversion instrument in like form for the unexercised portion thereof which has not expired.

(h) Common Shares. The Common Shares issued pursuant to this Instrument shall:

(i) rank equally in all respects from the effective date of issue with the Common Shares then in issue (if any);

(ii) be entitled to all dividends and distributions declared or paid on any date or by reference to any date on or after the date on which the relevant Notice of Conversion is delivered to the Principal Office (or at such other address as the Company may designate by notice in writing to the Holder in accordance with the terms hereof); and

(iii) otherwise have the rights and privileges under applicable law and as prescribed in the Organization Documents of the Company from time to time.

(i) Automatic Exercise. Unless the Holder has expressly notified the Company in writing at least five (5) Business Days prior to the Expiration Date that such Holder either (a) elects not to exercise the conversion rights under this Instrument and that such Holder will instead let this Instrument expire on the Expiration Date or (b) will exercise the conversion rights under this Instrument on or prior to the Expiration Date by a method other than as set forth in this Section 2(i), if the Fair Market Value Per Common Share determined as of the Expiration Date is greater than the Conversion Price then in effect, the Holder shall be deemed, without further act by the Holder (and, for avoidance of doubt, without any delivery of this Instrument or the Notice of Conversion to the Company), for all purposes of this Instrument, to have automatically exercised in full, by a Net Exercise in accordance with Section 2(c), its conversion rights under this Instrument on the Expiration Date (an “Automatic Exercise”). If the Expiration Date is expected to occur pursuant to clause (b) of the definition thereof, the Company shall deliver the Holder a written notice of such expected occurrence of such Expiration Date at least ten (10) Business Days prior to such expected occurrence of such Expiration Date with the view to allowing the Holder sufficient time to opt out of any Automatic Exercise on such expected Expiration Date.

(j) Company’s Failure to Timely Deliver Securities or Pay Cash Settlement Amount.

(i) The Company understands that a delay in the delivery of the Conversion Shares after the Share Delivery Date or payment of the Cash Settlement Amount after the applicable Cash Settlement Date could result in economic loss to the Holder. As compensation to the Holder for such loss, if the Company fails to (A) cause the Transfer Agent to transmit to the Holder the Conversion Shares on or before the Share Delivery Date in accordance with the provisions of Exhibit B pursuant to an exercise of the conversion rights under this Instrument (other than a failure caused by incorrect or incomplete information provided by the Holder to the Company) or (B) pay the Cash Settlement Amount to the Holder on or before the applicable Cash Settlement Date, the Company agrees to pay (as liquidated damages and not as a penalty) to the Holder for late issuance of the Conversion Shares the proportionate amount of $100 per Trading Day (increasing to $200 per Trading Day after the tenth (10^th) Trading Day) after the Share Delivery Date or the applicable Cash Settlement Date, as applicable, for each $10,000 of Aggregate Conversion Amount for which the conversion rights under this Instrument is exercised which are not

4

timely delivered or paid, respectively. Notwithstanding anything to the contrary contained in this Instrument, the Company shall not be required to pay any amounts under this Section 2(j) during the first five (5) Trading Days of any late issuance or delivery of Conversion Shares or Cash Settlement Amounts, as applicable, in connection with an Automatic Exercise.

(ii) Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Conversion Shares upon exercise of the conversion rights under this Instrument. The Company shall pay any payments incurred under this Section 2(j) in immediately available funds upon demand.

(k) Securities Law Legend(s). The Holder agrees and acknowledges, by receipt of this Instrument, that this Instrument, and any Conversion Shares issuable upon conversion hereof, shall bear a securities law legend substantially similar to the legend on the facing page of this Instrument, to the extent required by applicable securities laws. The Company acknowledges and agrees that Conversion Shares issuable upon exercise of the conversion rights under this Instrument shall not be required to contain any legend while a registration statement (including the Registration Statement) covering the resale of such Conversion Shares is effective under the Securities Act.

(l) Administrative Agent’s Acknowledgement. The Administrative Agent acknowledges the terms of this Instrument and agrees that, upon exercise of the conversion rights under this Instrument, the Administrative Agent shall perform its duties and exercise its rights and powers under the Credit Agreement, including, without limitation, in accordance with the terms of Section 2.14 thereof, to give effect to any corresponding deemed repayment of the Outstanding Amount of Loans under the Credit Agreement in an amount equal to the Aggregate Conversion Amount.

SECTION 3. Payment of Taxes. The Company shall promptly pay any and all stamp, documentary, registration or similar tax or taxes in connection with the entry into, performance, enforcement or admissibility in evidence of this Instrument or attributable to the initial issuance of Conversion Shares or other securities issuable upon the exercise of the conversion rights under this Instrument or issuable pursuant to Section 5 hereof, excluding any tax or taxes which may be payable because of the transfer involved in the issuance or delivery of any certificates for Conversion Shares or other securities in a name other than that of the Holder in respect of which such Conversion Shares or securities are issued. Any and all payments by or on account of any obligation of the Company hereunder (whether paid in cash or otherwise) shall be made free and clear of and without deduction or withholding for any taxes except as required by applicable law; provided that, if the Company is required to deduct or withhold any taxes hereunder then (a) the amount payable shall be increased as necessary so that, after making all required deductions or withholdings (including deductions or withholdings applicable to additional amounts payable under this Section 3), the Holder receives an amount (in cash or otherwise) equal to the amount it would have received had no such deduction or withholding been made; provided, that no gross-up shall be required in respect of Day 1 U.S. Federal Withholding Taxes, (b) the Company shall make such required deduction or withholding, and (c) the Company shall pay to the relevant taxation authority the full amount deducted or withheld in accordance with, and within the time limits prescribed by, applicable law. The Company shall provide the Holder with copies of receipts or other communications relating to the remittance of such withheld amount or the filing of such forms received from such taxation authority promptly after receipt thereof. The Company shall indemnify the Holder, within ten (10) days after written demand therefor, for the full amount of any taxes (other than taxes computed by reference to net income of the Holder) paid or payable by the Holder, on or with respect to any payment (whether paid in cash or otherwise) by or on account of any obligation of the Company hereunder (including taxes (other than taxes computed by reference to net income of the Holder) imposed or asserted on or attributable to amounts payable under this Section 3) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such taxes were correctly or legally imposed or asserted by the relevant taxation authority.

5

SECTION 4. Replacement Instrument. In case this Instrument is mutilated, lost, stolen or destroyed, the Company shall issue and deliver in exchange and substitution for and upon cancellation of the mutilated Instrument, or in lieu of and in substitution for the Instrument lost, stolen or destroyed, a new Instrument of like tenor and representing an equivalent right or interest, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of such Instrument and upon receipt of indemnity reasonably satisfactory to the Company; provided, that if the Holder is a financial institution, business development company or other institutional or fund investor, its own agreement shall be satisfactory.

SECTION 5. Adjustments to the Conversion Price.

Under certain conditions, the Conversion Price is subject to adjustment as set forth in this Section 5.

(a) Adjustments. The Conversion Price, after taking into consideration any prior adjustments pursuant to this Section 5, shall be subject to adjustment from time to time as follows and, thereafter, as adjusted, shall be deemed to be the then applicable Conversion Price hereunder, subject to further adjustment.

(i) Common Share Distributions. Subdivisions and Combinations. In case at any time or from time to time the Company shall:

(A) issue to the holders of its Common Shares a dividend payable in, or other distribution of, Common Shares, bonus shares or other Equity Interests of the Company (a “Share Distribution”),

(B) subdivide its issued Common Shares into a larger number of Common Shares, including without limitation, by means of a stock split (a “Share Subdivision”), or

(C) combine its issued Common Shares into a smaller number of Common Shares (a “Share Combination”),

then the Conversion Price shall be (x) proportionately decreased in the case of a Share Distribution or a Share Subdivision and (y) proportionately increased in the case of a Share Combination. In the event the Company shall declare or pay, without consideration, any dividend on the Common Shares payable in any right to acquire Common Shares for no consideration, then the Company shall be deemed to have made a Share Distribution in an amount of Common Shares equal to the maximum number of Common Shares issuable upon exercise of such rights to acquire Common Shares. Any adjustment under this Section 5(a) shall become effective at the close of business on the date the Share Subdivision or Share Combination becomes effective, or upon the making of any Share Distribution.

(ii) Distributions. If the Company, at any time while this Instrument is outstanding, distributes to all holders of Common Shares for no consideration (A) evidence of its indebtedness, (B) any security (other than a Share Distribution), (C) rights or warrants to subscribe for or purchase any security (other than any deemed Share Distribution referred to in Section 5(a)(i)), or (D) any other asset, including cash or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction (in each case, “Distributed Property”), then, upon any exercise of the conversion rights under this Instrument that occurs after the record date fixed for determination of shareholders entitled to receive such distribution, the Holder shall be entitled to receive, in addition to the Conversion Shares otherwise issuable upon such exercise (if applicable), the Distributed Property that such Holder would have been entitled to receive in respect of such number of Conversion Shares had the Holder been the record holder of such Conversion Shares in respect of the then-unexercised portion of this Instrument immediately prior to such record date without regard to any limitation on exercise contained therein.

6

(b) Fundamental Transactions. If, at any time while this Instrument is outstanding, the Company effects a Fundamental Transaction, then, to the extent then permitted under applicable laws, rules and regulations (including the rules of the Principal Market (or such other national securities exchange on which the Common Shares are then listed and traded), upon any subsequent exercise of the conversion rights under this Instrument, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash, assets or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Conversion Shares then issuable upon exercise in full of the conversion rights under this Instrument without regard to any limitations on exercise contained herein, subject to adjustments from and after the consummation date as nearly equivalent as possible to the adjustments provided for in this Section 5 (the “Alternate Consideration”). The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the consummation thereof, any successor to the Company or surviving entity shall have (i) assumed, by written instrument delivered to the Holder, the obligation to deliver to the Holder, such Alternate Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to receive, and the other obligations under this Instrument, and (ii) delivered to the Holder an opinion of counsel for such corporation or entity, satisfactory to the Holder, which opinion shall state that all of the terms of this Instrument applicable in respect of such Alternative Consideration shall be enforceable against the Company and such successor or surviving entity in accordance with the terms hereof and thereof, together with such other matters as the Holder may reasonably request. In any such case, appropriate provisions shall be made with respect to the rights and interest of the Holder so that the provisions hereof shall thereafter be applicable with respect to such Alternate Consideration deliverable upon exercise of the conversion rights hereunder, and appropriate equitable adjustments shall be made to the Conversion Price payable hereunder; provided that the Maximum Conversion Amount shall remain the same (and, for the avoidance of doubt, this Instrument shall be exclusively exercisable for such Alternate Consideration from and after the consummation of such Fundamental Transaction). The provisions of this Section 5(b) shall similarly apply to subsequent transactions analogous to a Fundamental Transaction.

(c) Notices.

(i) Notice of Proposed Actions. The Company shall give to the Holder advance written notice of any proposed action by the Company or any of its Subsidiaries pursuant to which an adjustment to the Conversion Price may occur pursuant to this Section 5 as promptly as practicable and in any event within five (5) Business Days after the approval of such action or entry into any agreement to give effective to such action, which written notice shall specify the proposed date on which a record is to be taken for the purposes of any Share Distribution or distribution of any Distributed Property, or the proposed date on which any reclassification, reorganization, consolidation, merger, stock exchange, sale, transfer, disposition, liquidation, dissolution, winding up, Fundamental Transaction or other transaction is to take place and the date of participation therein by the holders of Common Shares of the Company, if any such date is to be fixed, or the proposed date on which the transfer of Common Shares is to occur, and shall also set forth such facts with respect thereto as shall be necessary to indicate the effect of such action on the Common Shares and on the Conversion Price after giving effect to any adjustment which will be required as a result of such action.

(ii) Adjustment Notice. Whenever the Conversion Price is to be adjusted pursuant to this Section 5, unless otherwise agreed by the Holder, the Company shall promptly (and in any event within five (5) Business Days after the event requiring the adjustment) prepare and deliver to the Holder a certificate signed by the chief financial officer of the Company, setting forth, in reasonable detail, the event requiring the adjustment and the method by which such adjustment is to be calculated. The certificate shall set forth, if applicable, a description of the basis on which the Board in good faith determined, as applicable, the equitable nature of any adjustment under Section 5(b) hereof and the new Conversion Price, as applicable.

7

SECTION 6. No Dilution or Impairment. The Company will not, by amendment of its Organization Documents or through any reorganization, recapitalization, transfer of assets, consolidation, merger, share exchange, dissolution or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Instrument, including, without limitation, the adjustments required under Section 5 hereof, if any, and will at all times in good faith assist in the carrying out of all such terms and in taking of all such action as may be necessary or appropriate to protect the rights of the Holder against dilution or other impairment, subject to compliance with applicable securities laws and stock exchange rules and regulations. Without limiting the generality of the foregoing and notwithstanding any other provision of this Instrument to the contrary (including by way of implication), the Company will take all such action as may be necessary or appropriate so that the Company may validly and legally issue Conversion Shares to the Holder upon the exercise of the conversion rights under this Instrument.

SECTION 7. Transfers of this Instrument.

(a) Generally. Subject to the restrictions set forth in this Section 7, the Holder may, at any time and from time to time, assign or transfer this Instrument and the Conversion Shares, in each case in whole or in part, without the prior written consent of the Company. The transferor shall be deemed to remain the holder of this Instrument until the name of the transferee is entered in the Company register in respect of this Instrument. This Instrument has not been, and the Conversion Shares at the time of their issuance may not be, registered under the Securities Act or qualified or registered under any applicable Canadian securities laws. Accordingly, the Company’s obligation to issue Conversion Shares upon exercise of this Instrument by any such transferee shall be subject to compliance with applicable securities laws, and the Company reserves the right to obtain such information from the transferee as it may reasonably request to confirm the applicability of an available exemption from registration or qualification under applicable securities laws, including, without limitation, confirmation of representations and warranties substantially similar to those set forth in Section 12. This Instrument and the Conversion Shares are issued or issuable subject to the provisions and conditions contained herein and in the Credit Agreement and to the provisions and conditions contained in the Organization Documents of the Company, and the Holder by accepting the same agrees with the Company to such provisions and conditions, and represents to the Company that this Instrument has been acquired and the Conversion Shares will be acquired for the account of the Holder for investment and not with a view to or for sale in connection with any distribution thereof.

(b) Compliance with Securities Laws. The Holder agrees that this Instrument and the Conversion Shares may not be sold or otherwise disposed of except pursuant to (i) an effective registration statement under the Securities Act covering the re-sale by the Holder of the Conversion Shares, and applicable U.S. state securities laws or pursuant to an applicable exemption from the registration requirements of the Securities Act and such U.S. state securities laws, and (ii) a prospectus filed under applicable Canadian securities laws covering the sale by the Holder of the Conversion Shares or pursuant to an applicable exemption from such Canadian securities law requirements.

(c) No Transfer to Non-Lenders. The Holder agrees that this Instrument may not be assigned, transferred or sold to any Person who is not a Lender under the Credit Agreement.

SECTION 8. Confidentiality. The Holder hereby agrees to comply with and be bound by, and agrees to require a transferee permitted hereby to be bound by, the confidentiality provisions in Section 11.07 of the Credit Agreement and acknowledges and agrees that (a) any information provided to the Holder or its representatives pursuant to this Instrument, (b) any other information provided to the Holder or its representatives that a reasonable person would deem to be confidential under the circumstances, and (c) any other information provided to the Holder or its representatives pursuant to this Instrument and is clearly identified at the time of delivery as confidential shall, in each case, be deemed Information (as defined in the Credit Agreement) and subject to the confidentiality provisions in Section 11.07 of the Credit Agreement.

8

SECTION 9. Covenants. The Company hereby covenants and undertakes to the Holder that for so long as the Holder holds this Instrument, any interest created under this Instrument or any Conversion Shares:

(a) Validly Issued Shares. All Conversion Shares issuable upon exercise of the conversion rights under this Instrument and full conversion of the Aggregate Conversion Amount (including those issued pursuant to adjustments as required pursuant to Section 5 hereof) shall, upon delivery by the Company, be duly authorized and validly issued, fully paid and nonassessable, free from all stamp taxes, liens and charges with respect to the issue or delivery thereof and otherwise free of all other security interests, encumbrances and claims (other than security interests, encumbrances and claims to which the Holder is subject prior to or upon the issuance of the applicable Conversion Shares or pursuant to the Credit Agreement, restrictions under applicable federal, provincial, territorial and/or state securities laws and other transfer restrictions described herein).

(b) Reservation of Shares. The Company shall at all times reserve and keep available for issue out of the aggregate of its authorized but unissued share capital, free of preemptive rights, such number of its duly authorized Common Shares as shall be required to enable the Company to issue Conversion Shares in the full amount required upon exercise in full of the conversion rights under this Instrument. If any Common Shares reserved or to be reserved for the purpose of the exercise of the conversion rights under this Instrument, or any shares or other securities reserved or to be reserved for the purpose of issuance pursuant to Section 5 hereof, require registration with or approval of any Governmental Authority under any federal or state law (other than securities laws) before such shares or other securities may be validly delivered upon exercise of the conversion rights under this Instrument, then the Company covenants that it will, at its sole expense, promptly secure such registration or approval, as the case may be (including, but not limited to, approvals or expirations of waiting periods required under the Hart Scott Rodino Antitrust Improvements Act).

(c) No Effect Upon Lending Relationship. Notwithstanding anything herein to the contrary, nothing contained in this Instrument shall affect, limit or impair the rights and remedies of the Holder or any of its Affiliates in its capacity as a lender to the Company pursuant to any agreement under which the Company has borrowed money from the Holder or any of its Affiliates. Without limiting the generality of the foregoing, the Holder, for itself or in any capacity with respect to any of its Affiliates in exercising its or its Affiliates’ respective rights as a lender, including making its decision on whether to foreclose on any collateral security, will have no duty to consider (i) its status or the status of any of its Affiliates as a direct or indirect equity holder of the Company, (ii) the equity of the Company or (iii) any duty it may have to any other direct or indirect equity holder of the Company, except as may be required under the Credit Agreement or by commercial law applicable to creditors generally, or as may be required under applicable securities laws.

(d) Compliance with Rule 144. The Company shall timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date of issuance set forth above pursuant to the Exchange Act. As long as the Holder owns any Conversion Securities, if the Company is not required to file reports pursuant to such securities laws, it will prepare and furnish to the Holder and make publicly available in accordance with Rule 144 such information as is required for the Holder to sell Conversion Securities under Rule 144. For so long as the Conversion Shares are not registered under an effective registration statement, the Company further covenants that it will take such further action as the Holder may reasonably request and cooperate in all respects with the Holder, including using its best efforts to provide instructions to the Transfer Agent in order to facilitate a sale or transfer of Conversion Shares, cause its legal counsel to issue a legal opinion to the Transfer Agent for such Conversion Shares if required by the Transfer Agent to effect the removal of the legend hereunder or procure the removal of any restrictive legend applicable to the Conversion Shares, all to the extent required from time to time to enable the Holder to sell such Conversion Shares without registration under the Securities Act in accordance with the requirements of the applicable exemptions provided by Rule 144, if available.

(e) Certain Amendments. The Company shall not adopt any amendment or modification of the Organization Documents of the Company that would adversely affect the Holder (in its capacity solely as a holder of this Instrument) without prior written consent of the Holder.

9

(f) Limitation on Certain Restrictions. The Company shall not, and will not permit or cause any of its Subsidiaries, directly or indirectly, to create or otherwise cause or suffer to exist or become effective any restriction or encumbrance (other than the Credit Agreement) on the ability of the Company and any such Subsidiaries to perform and comply with their respective obligations under this Instrument.

(g) Regulatory Requirements and Restrictions. In the event of any reasonable determination by the Holder that, by reason of any existing or future national, federal or state law, statute, rule, regulation, guideline, order, court or administrative ruling, request or directive (whether or not having the force of law and whether or not failure to comply therewith would be unlawful) including bank holding company related laws (collectively, a “Regulatory Requirement”), the Holder is effectively restricted or prohibited from holding this Instrument or the Conversion Shares (including any shares of capital stock or other securities distributable to the Holder in any merger, reorganization, readjustment or other reclassification), or otherwise realizing upon or receiving the benefits intended under this Instrument, the Company shall, and shall use its reasonable best efforts to take such action as the Holder and the Company shall jointly agree in good faith to be necessary to permit the Holder to comply with such Regulatory Requirement; provided, that, no action shall be required to be taken by the Company that would (i) require the Company or any of its Subsidiaries to change its line of business or effect any transactions involving the Company or any of its Subsidiaries (including, but not limited to, any corporate reorganization); (ii) materially interfere or would reasonably be expected to materially interfere with any financing, acquisition, corporate reorganization, merger, tender offer or other significant transaction involving the Company; (iii) require the Company to obtain shareholder approval; (iv) require the Company or any of its Subsidiaries to re-incorporate under the laws of any other jurisdiction or to register pursuant to the rules or regulations of any regulatory agency; or (v) result in any adverse tax consequences to the Company or any of its Subsidiaries. The reasonable costs of taking such action, whether by the Company, any of its Subsidiaries, the Holder or otherwise, shall be borne in full by the Holder.

SECTION 10. Registration Rights.

(a) As soon as reasonably possible, but in any event, no later than twelve (12) calendar months following the Commencement Date (and subject to satisfaction of the Registration Conditions), the Company shall prepare and file a shelf registration statement with the Commission to permit the public resale of the Registrable Securities (the “Registration Statement”). The Registration Statement required to be filed with the Commission pursuant to this Section 10(a) shall be on Form F-3 or Form F-10, or, if neither Form F-3 nor Form F-10 is then available to the Company, on Form F-1, Form S-3, Form S-1 or such other form of registration statement as is then available to effect a registration for resale of the Registrable Securities, covering the Registrable Securities, and shall contain a prospectus in such form as to permit any the Holder to sell the Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect, or in the case of Form F-10, any similar provision under Canadian securities laws) at any time beginning on the effective date for such Registration Statement. The Company shall use its best efforts to cause a Registration Statement filed pursuant to this Section 10(a) to be declared effective by the Commission as soon as possible, but in any event, within one hundred twenty (120) calendar days after the filing of the Registration Statement. A Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holder, including by way of an underwritten offering, if so elected by the Holder, subject to a minimum offering size of $3,000,000. During the Effectiveness Period, the Company shall use its best efforts to cause a Registration Statement filed pursuant to this Section 10(a) to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another registration statement is available for the resale of the Registrable Securities until the Registration Termination Time. The Company shall prepare and file a listing application with the Principal Market for the Company’s Common Shares (including Nasdaq and TSX, if applicable, or such other national securities exchange on which the Company’s Common Shares are then listed and traded, in each case, to the extent required by the rules and regulations of such exchange) to list all Conversion Shares issuable upon exercise of the conversion rights under this Instrument covered by a Registration Statement and shall have such Conversion Shares issuable upon exercise of the conversion rights under this Instrument promptly approved for listing on such Principal Market (including Nasdaq and TSX, if applicable, or such other national securities

10

exchange on which the Common Shares are then listed and traded, in each case, to the extent required by the rules and regulations of such exchange) by the effective date of such Registration Statement, subject only to official notice of issuance. Within two (2) Business Days of the effective date of a Registration Statement, the Company shall notify the Holder of the effectiveness of such Registration Statement.

(b) When effective, a Registration Statement (including the documents incorporated therein by reference) shall comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made).

(c) Without limiting Section 10(a), the Company agrees that it shall notify the Holder in writing at least five (5) Business Days prior to the filing of any registration statement under the Securities Act for purposes of a proposed public offering of Common Shares (including, without limitation, registration statements relating to secondary offerings of securities of the Company, but excluding (i) any registration statement relating to any employee benefit plan; (ii) with respect to any corporate reorganization or transaction under Rule 145 promulgated under the Securities Act, any registration statement related solely to the issuance or resale of securities issued in such a transaction; (iii) any registration statement related solely to Common Shares issued upon conversion of convertible debt securities; (iv) any registration statement filed under Rule 462(b) promulgated under the Securities Act; or (v) any registration statement on Form S-4, Form F-4 or Form S-8 not contemplated by clauses (i) through (iv) hereof) that would be filed at any time during which this Instrument is still outstanding and the Holder (together with the Holder’s Affiliates who are holders of the other conversion instruments forming the same series with this Instrument) continues to hold or beneficially own Registrable Securities that comprise at least one percent (1%) of the Common Shares then outstanding, and the Company will afford the Holder an opportunity to include in such registration statement all or part of the Registrable Securities, subject to the provisions hereof (such registration statement, the “Piggyback Registration Statement”). If the Holder desires to include in any such Piggyback Registration Statement all or any part of the Registrable Securities held by it, the Holder shall, within three (3) Business Days after the above-described notice from the Company, so notify the Company in writing and shall thereafter furnish the Company with such information as the Company reasonably requires to include such Registrable Securities in such offering; provided that, if such Registrable Securities represent Conversion Shares that have not yet been issued upon exercise of this Instrument, then the Holder shall also include a Notice of Conversion in respect of such Registrable Securities, it being understood that in no event shall the Company be obligated to include in any such Piggyback Registration Statement any Conversion Shares that have not been, or will not be, actually issued prior to the closing of the applicable offering due solely to the Holder’s failure to timely deliver such Notice of Conversion to the Company. The Company will use its commercially reasonable efforts to cause such Registrable Securities as to which inclusion shall have been so requested to be included in the Piggyback Registration Statement, subject to the second proviso in the next sentence. The Holder shall be entitled to sell the Registrable Securities included in a Piggyback Registration Statement in accordance with the method of distribution contemplated in the Piggyback Registration Statement; provided that, if the Piggyback Registration Statement relates to an underwritten offering, then (A) the Company shall be entitled to select the underwriters in its sole discretion and (B) the Holder must sell all Registrable Securities included on the Piggyback Registration Statement in such underwritten offering pursuant to an underwriting agreement containing terms and conditions that are customary for secondary offerings; and provided, further, that if the number of Registrable Securities requested by the Holder, together with the number of Common Shares that other persons that have duly requested to be included in such Piggyback Registration Statement pursuant to “piggyback rights” evidenced by another agreement (including, without limitation, the Existing Registration Rights Agreement) (collectively, “Requested Shares”), exceeds the maximum number of securities that may be sold in the applicable offering under such Piggyback Registration Statement without adversely affecting the success of such offering, as advised by the managing underwriters for such offering, then the number of Requested Shares to be included in such Piggyback Registration Statement will be allocated first, to such other persons party to the Existing Registration Rights Agreement; second, to the Holder; and third, to any other such persons. The Company may withdraw a Piggyback Registration Statement prior to its being declared effective

11

without incurring any liability to the Holder and shall not be required to keep a Piggyback Registration Statement effective for longer than the period contemplated by the intended manner of distribution for the securities of the Company to be sold by the Company as described in the prospectus included in the Piggyback Registration Statement.

(d) For the avoidance of doubt, the rights to cause the Company to register Registrable Securities granted to the Holder by the Company under this Section 10 shall be fully assignable and transferrable to the same extent as this Instrument and the Conversion Shares are assignable and transferrable pursuant to Section 7 hereof, and any assignee or transferee of any Conversion Securities shall have all of the rights of the Holder to cause the Company to register Registrable Securities as set forth in this Section 10.

(e) The Holder (or any assignee or transferee) shall cooperate with the Company by, with reasonable promptness, supplying information and executing documents relating to such Holder (or transferee or assignee) or the securities of the Company owned by such Holder (or transferee or assignee) in connection with such registration under this Section 10 which are customary for offerings of this type or are required by applicable laws or regulations, including, but not limited to, furnishing to the Company a completed questionnaire in the form attached to this Instrument as Exhibit C. In the event the Holder does not comply with the immediately preceding sentence within a reasonable time prior to the initial filing in connection with such registration, the Company shall be permitted to exclude the Holder as a selling securityholder in connection therewith. In addition, the right of the Holder to include any of its Registrable Securities in any underwritten offering pursuant to a Piggyback Registration Statement will be subject to the execution and delivery by such Holder or its duly authorized representative or attorney-in-fact, of any related underwriting agreement and such other agreements or instruments (including customary “lock-up” agreements, custody agreements and powers of attorney), if any, as may be reasonably requested (to the same extent any such request is also made to the Company’s directors or officers and/or other selling shareholders in such offering) by the managing underwriters for such offering.

(f) Notwithstanding the foregoing provisions of this Section 10, the Company may, at any time, (i) delay the filing or delay or suspend the effectiveness of a Registration Statement, Piggyback Registration Statement or any pending or potential offering thereunder; (ii) without suspending such effectiveness, instruct the Holder not to sell any securities included in a Registration Statement or Piggyback Registration Statement; or (iii) delay the filing of any amendment or supplement to any Registration Statement or Piggyback Registration Statement, if, in the case of any of clause (i), (ii) or (iii), the Board has determined and promptly delivers a notice (a “Suspension Notice”) to the Holder in writing that in its reasonable good faith judgment (A) a material event has occurred or is likely to occur with respect to the Company that has not been publicly disclosed and, if disclosed, could reasonably be expected to materially and adversely affect the Company and its ability to consummate the registration of the resale of the Registrable Securities or (B) such registration could reasonably be expected to materially interfere with any material financing, acquisition, corporate reorganization, merger, tender offer or other significant transaction involving the Company (a “Suspension Period”), by providing the Holder with written notice of such Suspension Period and the reasons therefor.

PROCEDURES FOR ISSUANCE OF CONVERSION SHARES UPON EXERCISE

The procedures, rights and obligations set forth in this Exhibit B shall apply to the issuance and settlement of Conversion Shares pursuant to any Notice of Conversion delivered by the Holder or any Automatic Exercise, as applicable, pursuant to the attached Instrument, unless the Cash Settlement Amount is paid or proposed to be paid in accordance with Section 2(d) of the attached Instrument. Capitalized terms used but not otherwise defined herein have the meanings ascribed thereto in the attached Instrument.

(a) (x) Unless otherwise designated by the Holder in the applicable Notice of Conversion, on or before the fifth (5^th) Trading Day following the date on which the Company has received such Notice of Conversion; provided, that, such date shall be extended by up to five (5) Trading Days in the event the Company is required to adjust the Conversion Price in accordance with Section 5 of the attached Instrument, or (y) following any Automatic Exercise, on the Expiration Date (as applicable, the “Share Delivery Date”), the Company shall:

(i) if (A) there is an effective registration statement filed pursuant to the Securities Act covering the resale of such Conversion Shares by the Holder and (B) it is not otherwise deemed necessary under applicable securities laws for a restrictive legend to be affixed on such Conversion Shares upon issuance to the Holder, and, in each case, the Transfer Agent is participating in The Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program (“FAST”), upon the request of the Holder, credit such aggregate number of Conversion Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system; or

(ii) if (A) there is no effective registration statement filed pursuant to the Securities Act covering the resale of such Conversion Shares by the Holder, (B) it is deemed necessary under applicable securities laws for a restrictive legend to be affixed on such Conversion Shares upon issuance to the Holder, and/or (C) if the Transfer Agent is not then participating in the DTC’s FAST, upon the request of the Holder, issue and deliver (via reputable overnight courier) to the address as specified in the Notice of Conversion (or, in the case of an Automatic Exercise, to any address specified by the Holder in writing), a Direct Registration System statement, registered in the name of the Holder or its designee, for the number of Conversion Shares to which the Holder shall be entitled pursuant to such exercise, and if applicable, including a restrictive legend thereon.

If any restrictive legend is placed on Conversion Shares, the Company agrees that, as promptly as practicable following the Legend Removal Date (as defined below) in respect of such Conversion Shares, it will, subject to receipt of such representations and covenants of the Holder and the Holder’s executing broker, if any, as the Company or the Transfer Agent may reasonably require in connection therewith, deliver or cause to be delivered to the Holder a book entry position representing such Conversion Shares that is free from any restrictive legend (and the Company shall cause to be issued any legal opinion required by the Transfer Agent with respect thereto). The Company shall not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this section, except as may be required under applicable securities laws. To the extent that book entry positions are issued representing the Conversion Shares, such book entry positions subject to legend removal hereunder shall be delivered by the Transfer Agent to the Holder by issuing to the Holder by electronic delivery at the applicable balance account at DTC, the Transfer Agent or any custodian of the Holder, as applicable, at the Holder’s election. Any fees (with respect to the Transfer Agent, the Company’s counsel or otherwise) associated with the issuance of such opinion or the removal of such legend shall be borne by the Company. “Legend Removal Date”, in respect of any Conversion Shares, means the earliest of the date that (A) the

Company has received appropriate notice from the Holder that such Conversion Shares have been or are being sold or transferred pursuant to an effective registration statement under the Securities Act, (B) the Company has received appropriate notice from the Holder that such Conversion Shares have been or are being sold or transferred pursuant to Rule 144 (if the transferor is not an affiliate of the Company); or (C) the Company has received appropriate notice from the Holder that such Conversion Shares are eligible for resale under Rule 144 without volume or manner-of-sale restrictions.

(b) Upon delivery of a Notice of Conversion or any Automatic Exercise, as applicable, the Holder shall be deemed to have become the registered legal and beneficial owner of the Conversion Shares with respect to which the conversion rights under this Instrument have been exercised, irrespective of the date such Conversion Shares are credited to the Holder’s DTC account or the date of delivery of the certificate(s) evidencing such Conversion Shares (as the case may be). If the attached Instrument is submitted in connection with any exercise of the conversion rights pursuant to Section 2(e) of the attached Instrument and the Maximum Conversion Amount then available for conversion into Conversion Shares is greater than the Aggregate Conversion Amount being converted into Conversion Shares upon such exercise, then, at the request of the Holder, the Company shall as soon as practicable and in no event later than two (2) Business Days after the date of settlement pursuant to Section 2(e) of the attached Instrument and, at its own expense, issue and deliver to the Holder (or its designee) a new conversion instrument representing the right to convert the newly calculated maximum amount, after giving effect to such exercise, of the Outstanding Amount of Loans owing to the Holder for subscription for Conversion Shares (such newly calculated maximum amount being an amount equal to (i) the Maximum Conversion Amount which was available for conversion immediately prior to such exercise, minus (ii) the Aggregate Conversion Amount for such exercise).

(c) The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation, fees and expenses of the Transfer Agent) that may be payable with respect to the issuance of Conversion Shares upon exercise of the conversion rights under the attached Instrument (but not any subsequent transfer of Conversion Shares so issued).

(d) Notwithstanding any other provision in this Agreement, the Holder may elect, at its sole discretion, to receive unregistered Conversion Shares issued in response to a Notice of Conversion or any Automatic Exercise instead of Conversion Shares registered pursuant to any registration statement filed with the Commission to register the Conversion Shares. In such case, the Holder agrees and acknowledges that any such unregistered Conversion Shares shall bear a securities law legend substantially similar to the legend on the facing page of the attached Instrument, to the extent required by applicable securities laws.

TWELFTH AMENDED AND RESTATED COMMON SHARE CONVERSION INSTRUMENT

Amended and Restated: December 30, 2023

Date of Issuance: July 14, 2022

Series No. 2022-A

Certificate No. 2

THIS IS TO CERTIFY that Madryn Health Partners II (Cayman Master), LP and its transferees, successors and assigns (the “Holder”) shall have the right (but not the obligation) to convert the Outstanding Amount of Loans owing to the Holder under the Credit Agreement, up to the Maximum Conversion Amount then available, into common shares, without par value (the “Common Shares”) in the capital of Greenbrook TMS Inc., a corporation incorporated under the laws of the Province of Ontario (the “Company”), at the initial conversion price of $1.90 per Common Share (the “Conversion Price”), at any time after the date of issuance listed above (the “Commencement Date”) and expiring on the Expiration Date. This Twelfth Amended and Restated Common Share Conversion Instrument (this “Instrument”) is issued subject to the Organization Documents of the Company and under and pursuant to that certain Credit Agreement, dated as of July 14, 2022, by and among the Company, the Holder, and the other parties thereto (as amended, modified or supplemented from time to time, the “Credit Agreement”). Capitalized terms used herein shall have the meanings ascribed to such terms in Section 13 hereof unless otherwise defined herein.

This Instrument amends, restates and replaces in its entirety that certain Eleventh Amended and Restated Common Share Conversion Instrument dated as of December 19, 2023, issued by the Company to the Holder.

SECTION 1. The Instrument; Transfer and Exchange.

(a) The Instrument. This Instrument and the rights and privileges of the Holder hereunder may be exercised in whole or in part as provided herein and, as more fully set forth in Section 1(b) and Section 7 hereof, may, subject to applicable securities laws and the terms of this Instrument, be transferred by the Holder to any other Person or Persons who meet the requirements set forth herein at any time or from time to time, in whole or in part.

(b) Transfer and Exchanges. The Company shall initially record this Instrument in a register maintained by the Company for that purpose and subject to Section 7 hereof, from time to time thereafter shall reflect the transfer of this Instrument on such register when surrendered for transfer in accordance with the terms hereof and properly endorsed, accompanied by appropriate instructions, and further accompanied by payment in cash or by check, bank draft or money order payable to the order of the Company, in United States currency, of

an amount equal to any stamp or other tax or governmental charge or fee required to be paid in connection with the transfer thereof. Upon any such transfer, a new conversion instrument or conversion instruments shall be issued to and in the name of the transferee and the Holder (in the event this Instrument is only partially transferred or in connection with any concurrent partial transfer and partial exercise) and the surrendered conversion instrument shall be canceled and the Company shall update the register accordingly. This Instrument may be exchanged at the option of the Holder, when surrendered at the Principal Office of the Company, for another conversion instrument or other conversion instruments of like tenor and representing in the aggregate the right to convert a like amount of the Outstanding Amount of Loans owing to the Holder under the Credit Agreement, up to the Maximum Conversion Amount then available, into a like number of Common Shares at the Conversion Price (as such number may be adjusted upon adjustment of the Conversion Price as provided in Section 5).

SECTION 2. Exercise.

(a) Right to Exercise. At any time after the Commencement Date and on or before the Expiration Date, the Holder, in accordance with applicable securities laws and the terms hereof, shall be entitled to exercise the conversion rights under this Instrument, in whole at any time or in part from time to time, by delivering this Instrument to the Company during normal business hours on any Business Day at the Company’s Principal Office, together with the Notice of Conversion (with a copy to the Administrative Agent), in the form attached hereto as Exhibit A and made a part hereof (the “Notice of Conversion”), duly executed. The Holder shall not be required to deliver the original of this Instrument in order to effect an exercise hereunder. Subject to Section 2(c), the aggregate number of Conversion Shares to be subscribed for by the Holder pursuant to the applicable Notice of Conversion shall be equal to the amount calculated by dividing (i) the Aggregate Conversion Amount by (ii) the Conversion Price then in effect.

(b) Conversion of the Aggregate Conversion Amount. For any exercise, in whole or in part, of the conversion rights under this Instrument, payment of the Aggregate Conversion Amount shall be made to the Company by (i) automatically reducing the Outstanding Amount of the Loans owing to the Holder under the Credit Agreement by an amount equal to the Aggregate Conversion Amount or (ii) a Net Exercise as provided in Section 2(c). Other than in the case of a Net Exercise in accordance with Section 2(c), simultaneously with the allotment and issuance of Conversion Shares, or the payment of the applicable Cash Settlement Amount, as the case may be, pursuant to Section 2(e), the Outstanding Amount of the Loans in an amount equal to the Aggregate Conversion Amount shall be deemed repaid under the Credit Agreement in accordance with Section 2.14 thereof. Following any exercise, in whole or in part, of the conversion rights under this Instrument, the Maximum Conversion Amount available for any subsequent exercise of the conversion rights under this Instrument shall be reduced by the Aggregate Conversion Amount paid by the Holder in connection with such exercise.

(c) Net Exercise. The Holder shall have the right to pay all or a portion of the Aggregate Conversion Amount by making a net exercise (“Net Exercise”), in which case the portion of the Aggregate Conversion Amount to be so paid shall be paid by reducing the number of Conversion Shares otherwise issuable pursuant to the Notice of Exercise by an amount equal to (i) the Aggregate Conversion Amount to be so paid, divided by (ii) the Fair Market Value Per Common Share. For the avoidance of doubt, in the case of a Net Exercise by the Holder, no amount of the Outstanding Amount of the Loans owing to the Holder under the Credit Agreement shall be reduced or deemed repaid.

(d) Cash Settlement.

(i) Notwithstanding any other provision of this Instrument, if, following the exercise of the conversion rights under this Instrument, (A) the applicable rules of the Toronto Stock Exchange (“TSX”) or The Nasdaq Stock Market LLC (“Nasdaq”) require approval by TSX or Nasdaq, as applicable, for any allotment or issuance of any number of Conversion Shares by the Company with respect to all or any portion of the Aggregate Conversion Amount, and the Company is unable to obtain such approval by using commercially reasonable efforts, (B) on or prior to the Share Delivery Date, the Company makes a written request to satisfy its obligations under this Instrument by means other than such allotment and

2

issuance of such number of Conversion Shares, and the Holder, in its sole and absolute discretion, accepts such request, or (C) the Company fails for any reason to allot and issue the applicable number of Conversion Shares with respect to all or any portion of the Aggregate Conversion Amount on or prior to the Share Delivery Date, and the Holder, in its sole and absolute discretion, elects to require the Company to satisfy its obligations under this Instrument by means other than such allotment and issuance of such applicable number of Conversion Shares (any such portion of the Aggregate Conversion Amount referred to in Section 2(d)(i)(A), (B) or (C), the “Non-Share Settled Portion”), then, in each case, the Company shall, in lieu of allotting and issuing to the Holder the applicable number of Conversion Shares with respect to the Non-Share Settled Portion, pay the applicable Cash Settlement Amount to the Holder for such Non-Share Settled Portion. Notwithstanding the foregoing, in the case of any Automatic Exercise pursuant to Section 2(i), the Company shall not be permitted to satisfy its obligations under this Instrument by means of payment of the applicable Cash Settlement Amount to the Holder, other than payment of the Cash Settlement Amount for the Non-Share Settled Portion referred to in Section 2(d)(i)(A).

(ii) The cash settlement amount (the “Cash Settlement Amount”) for any Non-Share Settled Portion shall be calculated as of the date of exercise of this Instrument and shall be equal to the product of (A) the Fair Market Value Per Common Share, multiplied by (B) the number of Conversion Shares which would, but for the occurrence of any event referred to in Section 2(d)(i)(A), (B) or (C), have been issuable to the Holder upon exercise of the conversion rights under this Instrument with respect to such Non-Share Settled Portion.

(iii) The Company shall be required to pay any Cash Settlement Amount to the Holder on or before the following applicable date (each, a “Cash Settlement Date”): (A) if such payment is required under Section 2(d)(i)(A), the Share Delivery Date; (B) if such payment is required under Section 2(d)(i)(B), the fifth (5^th) Business Day following the date of the Holder’s acceptance of the written request of the Company referred to in Section 2(d)(i)(B); or (C) if such payment is required under Section 2(d)(i)(C), the third (3^rd) Business Day following the date of the Holder’s election referred to Section 2(d)(i)(C). Notwithstanding the foregoing, the Cash Settlement Date (other than the Cash Settlement Date in connection with any Cash Settlement Amount to be paid upon any Automatic Exercise) shall be extended by up to five (5) Business Days in the event the Company is required to adjust the Conversion Price in accordance with Section 5.

(iv) The Company covenants and agrees that, after the date of issuance set forth above, it shall not, without the prior written consent of the Holder, enter into or agree to become subject to specific or direct contractual term, condition, provision or agreement that would specifically prohibit the performance of the Company’s obligations to pay the applicable Cash Settlement Amount under this Section 2(d).

(e) Issuance of Conversion Shares or Payment of Cash Settlement Amount Upon Exercise. Upon (x) receipt by the Company of a Notice of Conversion at its Principal Office in proper form for exercise or (y) any Net Exercise as provided in Section 2(c) or any Automatic Exercise as provided in Section 2(i), the Company shall:

(i) allot and issue to the Holder, without delay and in any case on or prior to the Share Delivery Date, the number of Conversion Shares specified in the Notice of Conversion as set forth in Exhibit B hereto; or

(ii) if applicable, pay to the Holder the applicable Cash Settlement Amount in accordance with Section 2(d),

and, in each case, simultaneously deliver to the Holder, without duplication, all Distributed Property that the Holder is entitled to receive pursuant to Section 5(a)(ii).

3

(f) Fractional Shares. If any fraction of a Conversion Share would be deliverable upon an exercise of this Instrument, the Company may, in lieu of delivering such fraction of a Conversion Share, make a cash payment to the Holder in an amount equal to the same fraction of the Fair Market Value Per Common Share determined as of the date of exercise of this Instrument.

(g) Partial Exercise. In the event that the Holder exercises this Instrument in part from time to time, there shall be no restriction on the number of times the Holder may exercise its conversion rights under this Instrument to subscribe for Conversion Shares or the minimum number of Conversion Shares that the Holder shall be required to subscribe for upon any partial exercise of its conversion rights under this Instrument. Upon any partial exercise of this Instrument, the Company shall issue and deliver to the Holder a new conversion instrument in like form for the unexercised portion thereof which has not expired.

(h) Common Shares. The Common Shares issued pursuant to this Instrument shall:

(i) rank equally in all respects from the effective date of issue with the Common Shares then in issue (if any);

(ii) be entitled to all dividends and distributions declared or paid on any date or by reference to any date on or after the date on which the relevant Notice of Conversion is delivered to the Principal Office (or at such other address as the Company may designate by notice in writing to the Holder in accordance with the terms hereof); and

(iii) otherwise have the rights and privileges under applicable law and as prescribed in the Organization Documents of the Company from time to time.

(i) Automatic Exercise. Unless the Holder has expressly notified the Company in writing at least five (5) Business Days prior to the Expiration Date that such Holder either (a) elects not to exercise the conversion rights under this Instrument and that such Holder will instead let this Instrument expire on the Expiration Date or (b) will exercise the conversion rights under this Instrument on or prior to the Expiration Date by a method other than as set forth in this Section 2(i), if the Fair Market Value Per Common Share determined as of the Expiration Date is greater than the Conversion Price then in effect, the Holder shall be deemed, without further act by the Holder (and, for avoidance of doubt, without any delivery of this Instrument or the Notice of Conversion to the Company), for all purposes of this Instrument, to have automatically exercised in full, by a Net Exercise in accordance with Section 2(c), its conversion rights under this Instrument on the Expiration Date (an “Automatic Exercise”). If the Expiration Date is expected to occur pursuant to clause (b) of the definition thereof, the Company shall deliver the Holder a written notice of such expected occurrence of such Expiration Date at least ten (10) Business Days prior to such expected occurrence of such Expiration Date with the view to allowing the Holder sufficient time to opt out of any Automatic Exercise on such expected Expiration Date.

(j) Company’s Failure to Timely Deliver Securities or Pay Cash Settlement Amount.

(i) The Company understands that a delay in the delivery of the Conversion Shares after the Share Delivery Date or payment of the Cash Settlement Amount after the applicable Cash Settlement Date could result in economic loss to the Holder. As compensation to the Holder for such loss, if the Company fails to (A) cause the Transfer Agent to transmit to the Holder the Conversion Shares on or before the Share Delivery Date in accordance with the provisions of Exhibit B pursuant to an exercise of the conversion rights under this Instrument (other than a failure caused by incorrect or incomplete information provided by the Holder to the Company) or (B) pay the Cash Settlement Amount to the Holder on or before the applicable Cash Settlement Date, the Company agrees to pay (as liquidated damages and not as a penalty) to the Holder for late issuance of the Conversion Shares the proportionate amount of $100 per Trading Day (increasing to $200 per Trading Day after the tenth (10^th) Trading Day) after the Share Delivery Date or the applicable Cash Settlement Date, as applicable, for each $10,000 of Aggregate Conversion Amount for which the conversion rights under this Instrument is exercised which are not timely delivered or paid, respectively. Notwithstanding anything to the contrary contained in this Instrument, the Company shall not be required to pay any amounts under this Section 2(j) during the first five (5) Trading Days of any late issuance or delivery of Conversion Shares or Cash Settlement Amounts, as applicable, in connection with an Automatic Exercise.

4

(ii) Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Conversion Shares upon exercise of the conversion rights under this Instrument. The Company shall pay any payments incurred under this Section 2(j) in immediately available funds upon demand.

(k) Securities Law Legend(s). The Holder agrees and acknowledges, by receipt of this Instrument, that this Instrument, and any Conversion Shares issuable upon conversion hereof, shall bear a securities law legend substantially similar to the legend on the facing page of this Instrument, to the extent required by applicable securities laws. The Company acknowledges and agrees that Conversion Shares issuable upon exercise of the conversion rights under this Instrument shall not be required to contain any legend while a registration statement (including the Registration Statement) covering the resale of such Conversion Shares is effective under the Securities Act.

(l) Administrative Agent’s Acknowledgement. The Administrative Agent acknowledges the terms of this Instrument and agrees that, upon exercise of the conversion rights under this Instrument, the Administrative Agent shall perform its duties and exercise its rights and powers under the Credit Agreement, including, without limitation, in accordance with the terms of Section 2.14 thereof, to give effect to any corresponding deemed repayment of the Outstanding Amount of Loans under the Credit Agreement in an amount equal to the Aggregate Conversion Amount.

SECTION 3. Payment of Taxes. The Company shall promptly pay any and all stamp, documentary, registration or similar tax or taxes in connection with the entry into, performance, enforcement or admissibility in evidence of this Instrument or attributable to the initial issuance of Conversion Shares or other securities issuable upon the exercise of the conversion rights under this Instrument or issuable pursuant to Section 5 hereof, excluding any tax or taxes which may be payable because of the transfer involved in the issuance or delivery of any certificates for Conversion Shares or other securities in a name other than that of the Holder in respect of which such Conversion Shares or securities are issued. Any and all payments by or on account of any obligation of the Company hereunder (whether paid in cash or otherwise) shall be made free and clear of and without deduction or withholding for any taxes except as required by applicable law; provided that, if the Company is required to deduct or withhold any taxes hereunder then (a) the amount payable shall be increased as necessary so that, after making all required deductions or withholdings (including deductions or withholdings applicable to additional amounts payable under this Section 3), the Holder receives an amount (in cash or otherwise) equal to the amount it would have received had no such deduction or withholding been made; provided, that no gross-up shall be required in respect of Day 1 U.S. Federal Withholding Taxes, (b) the Company shall make such required deduction or withholding, and (c) the Company shall pay to the relevant taxation authority the full amount deducted or withheld in accordance with, and within the time limits prescribed by, applicable law. The Company shall provide the Holder with copies of receipts or other communications relating to the remittance of such withheld amount or the filing of such forms received from such taxation authority promptly after receipt thereof. The Company shall indemnify the Holder, within ten (10) days after written demand therefor, for the full amount of any taxes (other than taxes computed by reference to net income of the Holder) paid or payable by the Holder, on or with respect to any payment (whether paid in cash or otherwise) by or on account of any obligation of the Company hereunder (including taxes (other than taxes computed by reference to net income of the Holder) imposed or asserted on or attributable to amounts payable under this Section 3) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such taxes were correctly or legally imposed or asserted by the relevant taxation authority.

5

SECTION 4. Replacement Instrument. In case this Instrument is mutilated, lost, stolen or destroyed, the Company shall issue and deliver in exchange and substitution for and upon cancellation of the mutilated Instrument, or in lieu of and in substitution for the Instrument lost, stolen or destroyed, a new Instrument of like tenor and representing an equivalent right or interest, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of such Instrument and upon receipt of indemnity reasonably satisfactory to the Company; provided, that if the Holder is a financial institution, business development company or other institutional or fund investor, its own agreement shall be satisfactory.

SECTION 5. Adjustments to the Conversion Price.

Under certain conditions, the Conversion Price is subject to adjustment as set forth in this Section 5.

(a) Adjustments. The Conversion Price, after taking into consideration any prior adjustments pursuant to this Section 5, shall be subject to adjustment from time to time as follows and, thereafter, as adjusted, shall be deemed to be the then applicable Conversion Price hereunder, subject to further adjustment.

(i) Common Share Distributions. Subdivisions and Combinations. In case at any time or from time to time the Company shall:

(A) issue to the holders of its Common Shares a dividend payable in, or other distribution of, Common Shares, bonus shares or other Equity Interests of the Company (a “Share Distribution”),

(B) subdivide its issued Common Shares into a larger number of Common Shares, including without limitation, by means of a stock split (a “Share Subdivision”), or

(C) combine its issued Common Shares into a smaller number of Common Shares (a “Share Combination”),

then the Conversion Price shall be (x) proportionately decreased in the case of a Share Distribution or a Share Subdivision and (y) proportionately increased in the case of a Share Combination. In the event the Company shall declare or pay, without consideration, any dividend on the Common Shares payable in any right to acquire Common Shares for no consideration, then the Company shall be deemed to have made a Share Distribution in an amount of Common Shares equal to the maximum number of Common Shares issuable upon exercise of such rights to acquire Common Shares. Any adjustment under this Section 5(a) shall become effective at the close of business on the date the Share Subdivision or Share Combination becomes effective, or upon the making of any Share Distribution.

(ii) Distributions. If the Company, at any time while this Instrument is outstanding, distributes to all holders of Common Shares for no consideration (A) evidence of its indebtedness, (B) any security (other than a Share Distribution), (C) rights or warrants to subscribe for or purchase any security (other than any deemed Share Distribution referred to in Section 5(a)(i)), or (D) any other asset, including cash or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction (in each case, “Distributed Property”), then, upon any exercise of the conversion rights under this Instrument that occurs after the record date fixed for determination of shareholders entitled to receive such distribution, the Holder shall be entitled to receive, in addition to the Conversion Shares otherwise issuable upon such exercise (if applicable), the Distributed Property that such Holder would have been entitled to receive in respect of such number of Conversion Shares had the Holder been the record holder of such Conversion Shares in respect of the then-unexercised portion of this Instrument immediately prior to such record date without regard to any limitation on exercise contained therein.

6

(b) Fundamental Transactions. If, at any time while this Instrument is outstanding, the Company effects a Fundamental Transaction, then, to the extent then permitted under applicable laws, rules and regulations (including the rules of the Principal Market (or such other national securities exchange on which the Common Shares are then listed and traded), upon any subsequent exercise of the conversion rights under this Instrument, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash, assets or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Conversion Shares then issuable upon exercise in full of the conversion rights under this Instrument without regard to any limitations on exercise contained herein, subject to adjustments from and after the consummation date as nearly equivalent as possible to the adjustments provided for in this Section 5 (the “Alternate Consideration”). The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the consummation thereof, any successor to the Company or surviving entity shall have (i) assumed, by written instrument delivered to the Holder, the obligation to deliver to the Holder, such Alternate Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to receive, and the other obligations under this Instrument, and (ii) delivered to the Holder an opinion of counsel for such corporation or entity, satisfactory to the Holder, which opinion shall state that all of the terms of this Instrument applicable in respect of such Alternative Consideration shall be enforceable against the Company and such successor or surviving entity in accordance with the terms hereof and thereof, together with such other matters as the Holder may reasonably request. In any such case, appropriate provisions shall be made with respect to the rights and interest of the Holder so that the provisions hereof shall thereafter be applicable with respect to such Alternate Consideration deliverable upon exercise of the conversion rights hereunder, and appropriate equitable adjustments shall be made to the Conversion Price payable hereunder; provided that the Maximum Conversion Amount shall remain the same (and, for the avoidance of doubt, this Instrument shall be exclusively exercisable for such Alternate Consideration from and after the consummation of such Fundamental Transaction). The provisions of this Section 5(b) shall similarly apply to subsequent transactions analogous to a Fundamental Transaction.

(c) Notices.

(i) Notice of Proposed Actions. The Company shall give to the Holder advance written notice of any proposed action by the Company or any of its Subsidiaries pursuant to which an adjustment to the Conversion Price may occur pursuant to this Section 5 as promptly as practicable and in any event within five (5) Business Days after the approval of such action or entry into any agreement to give effective to such action, which written notice shall specify the proposed date on which a record is to be taken for the purposes of any Share Distribution or distribution of any Distributed Property, or the proposed date on which any reclassification, reorganization, consolidation, merger, stock exchange, sale, transfer, disposition, liquidation, dissolution, winding up, Fundamental Transaction or other transaction is to take place and the date of participation therein by the holders of Common Shares of the Company, if any such date is to be fixed, or the proposed date on which the transfer of Common Shares is to occur, and shall also set forth such facts with respect thereto as shall be necessary to indicate the effect of such action on the Common Shares and on the Conversion Price after giving effect to any adjustment which will be required as a result of such action.

(ii) Adjustment Notice. Whenever the Conversion Price is to be adjusted pursuant to this Section 5, unless otherwise agreed by the Holder, the Company shall promptly (and in any event within five (5) Business Days after the event requiring the adjustment) prepare and deliver to the Holder a certificate signed by the chief financial officer of the Company, setting forth, in reasonable detail, the event requiring the adjustment and the method by which such adjustment is to be calculated. The certificate shall set forth, if applicable, a description of the basis on which the Board in good faith determined, as applicable, the equitable nature of any adjustment under Section 5(b) hereof and the new Conversion Price, as applicable.

7

SECTION 6. No Dilution or Impairment. The Company will not, by amendment of its Organization Documents or through any reorganization, recapitalization, transfer of assets, consolidation, merger, share exchange, dissolution or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Instrument, including, without limitation, the adjustments required under Section 5 hereof, if any, and will at all times in good faith assist in the carrying out of all such terms and in taking of all such action as may be necessary or appropriate to protect the rights of the Holder against dilution or other impairment, subject to compliance with applicable securities laws and stock exchange rules and regulations. Without limiting the generality of the foregoing and notwithstanding any other provision of this Instrument to the contrary (including by way of implication), the Company will take all such action as may be necessary or appropriate so that the Company may validly and legally issue Conversion Shares to the Holder upon the exercise of the conversion rights under this Instrument.

SECTION 7. Transfers of this Instrument.

(a) Generally. Subject to the restrictions set forth in this Section 7, the Holder may, at any time and from time to time, assign or transfer this Instrument and the Conversion Shares, in each case in whole or in part, without the prior written consent of the Company. The transferor shall be deemed to remain the holder of this Instrument until the name of the transferee is entered in the Company register in respect of this Instrument. This Instrument has not been, and the Conversion Shares at the time of their issuance may not be, registered under the Securities Act or qualified or registered under any applicable Canadian securities laws. Accordingly, the Company’s obligation to issue Conversion Shares upon exercise of this Instrument by any such transferee shall be subject to compliance with applicable securities laws, and the Company reserves the right to obtain such information from the transferee as it may reasonably request to confirm the applicability of an available exemption from registration or qualification under applicable securities laws, including, without limitation, confirmation of representations and warranties substantially similar to those set forth in Section 12. This Instrument and the Conversion Shares are issued or issuable subject to the provisions and conditions contained herein and in the Credit Agreement and to the provisions and conditions contained in the Organization Documents of the Company, and the Holder by accepting the same agrees with the Company to such provisions and conditions, and represents to the Company that this Instrument has been acquired and the Conversion Shares will be acquired for the account of the Holder for investment and not with a view to or for sale in connection with any distribution thereof.

(b) Compliance with Securities Laws. The Holder agrees that this Instrument and the Conversion Shares may not be sold or otherwise disposed of except pursuant to (i) an effective registration statement under the Securities Act covering the re-sale by the Holder of the Conversion Shares, and applicable U.S. state securities laws or pursuant to an applicable exemption from the registration requirements of the Securities Act and such U.S. state securities laws, and (ii) a prospectus filed under applicable Canadian securities laws covering the sale by the Holder of the Conversion Shares or pursuant to an applicable exemption from such Canadian securities law requirements.

(c) No Transfer to Non-Lenders. The Holder agrees that this Instrument may not be assigned, transferred or sold to any Person who is not a Lender under the Credit Agreement.

SECTION 8. Confidentiality. The Holder hereby agrees to comply with and be bound by, and agrees to require a transferee permitted hereby to be bound by, the confidentiality provisions in Section 11.07 of the Credit Agreement and acknowledges and agrees that (a) any information provided to the Holder or its representatives pursuant to this Instrument, (b) any other information provided to the Holder or its representatives that a reasonable person would deem to be confidential under the circumstances, and (c) any other information provided to the Holder or its representatives pursuant to this Instrument and is clearly identified at the time of delivery as confidential shall, in each case, be deemed Information (as defined in the Credit Agreement) and subject to the confidentiality provisions in Section 11.07 of the Credit Agreement.

8

SECTION 9. Covenants. The Company hereby covenants and undertakes to the Holder that for so long as the Holder holds this Instrument, any interest created under this Instrument or any Conversion Shares:

(a) Validly Issued Shares. All Conversion Shares issuable upon exercise of the conversion rights under this Instrument and full conversion of the Aggregate Conversion Amount (including those issued pursuant to adjustments as required pursuant to Section 5 hereof) shall, upon delivery by the Company, be duly authorized and validly issued, fully paid and nonassessable, free from all stamp taxes, liens and charges with respect to the issue or delivery thereof and otherwise free of all other security interests, encumbrances and claims (other than security interests, encumbrances and claims to which the Holder is subject prior to or upon the issuance of the applicable Conversion Shares or pursuant to the Credit Agreement, restrictions under applicable federal, provincial, territorial and/or state securities laws and other transfer restrictions described herein).

(b) Reservation of Shares. The Company shall at all times reserve and keep available for issue out of the aggregate of its authorized but unissued share capital, free of preemptive rights, such number of its duly authorized Common Shares as shall be required to enable the Company to issue Conversion Shares in the full amount required upon exercise in full of the conversion rights under this Instrument. If any Common Shares reserved or to be reserved for the purpose of the exercise of the conversion rights under this Instrument, or any shares or other securities reserved or to be reserved for the purpose of issuance pursuant to Section 5 hereof, require registration with or approval of any Governmental Authority under any federal or state law (other than securities laws) before such shares or other securities may be validly delivered upon exercise of the conversion rights under this Instrument, then the Company covenants that it will, at its sole expense, promptly secure such registration or approval, as the case may be (including, but not limited to, approvals or expirations of waiting periods required under the Hart Scott Rodino Antitrust Improvements Act).

(c) No Effect Upon Lending Relationship. Notwithstanding anything herein to the contrary, nothing contained in this Instrument shall affect, limit or impair the rights and remedies of the Holder or any of its Affiliates in its capacity as a lender to the Company pursuant to any agreement under which the Company has borrowed money from the Holder or any of its Affiliates. Without limiting the generality of the foregoing, the Holder, for itself or in any capacity with respect to any of its Affiliates in exercising its or its Affiliates’ respective rights as a lender, including making its decision on whether to foreclose on any collateral security, will have no duty to consider (i) its status or the status of any of its Affiliates as a direct or indirect equity holder of the Company, (ii) the equity of the Company or (iii) any duty it may have to any other direct or indirect equity holder of the Company, except as may be required under the Credit Agreement or by commercial law applicable to creditors generally, or as may be required under applicable securities laws.

(d) Compliance with Rule 144. The Company shall timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date of issuance set forth above pursuant to the Exchange Act. As long as the Holder owns any Conversion Securities, if the Company is not required to file reports pursuant to such securities laws, it will prepare and furnish to the Holder and make publicly available in accordance with Rule 144 such information as is required for the Holder to sell Conversion Securities under Rule 144. For so long as the Conversion Shares are not registered under an effective registration statement, the Company further covenants that it will take such further action as the Holder may reasonably request and cooperate in all respects with the Holder, including using its best efforts to provide instructions to the Transfer Agent in order to facilitate a sale or transfer of Conversion Shares, cause its legal counsel to issue a legal opinion to the Transfer Agent for such Conversion Shares if required by the Transfer Agent to effect the removal of the legend hereunder or procure the removal of any restrictive legend applicable to the Conversion Shares, all to the extent required from time to time to enable the Holder to sell such Conversion Shares without registration under the Securities Act in accordance with the requirements of the applicable exemptions provided by Rule 144, if available.

(e) Certain Amendments. The Company shall not adopt any amendment or modification of the Organization Documents of the Company that would adversely affect the Holder (in its capacity solely as a holder of this Instrument) without prior written consent of the Holder.

9

(f) Limitation on Certain Restrictions. The Company shall not, and will not permit or cause any of its Subsidiaries, directly or indirectly, to create or otherwise cause or suffer to exist or become effective any restriction or encumbrance (other than the Credit Agreement) on the ability of the Company and any such Subsidiaries to perform and comply with their respective obligations under this Instrument.

(g) Regulatory Requirements and Restrictions. In the event of any reasonable determination by the Holder that, by reason of any existing or future national, federal or state law, statute, rule, regulation, guideline, order, court or administrative ruling, request or directive (whether or not having the force of law and whether or not failure to comply therewith would be unlawful) including bank holding company related laws (collectively, a “Regulatory Requirement”), the Holder is effectively restricted or prohibited from holding this Instrument or the Conversion Shares (including any shares of capital stock or other securities distributable to the Holder in any merger, reorganization, readjustment or other reclassification), or otherwise realizing upon or receiving the benefits intended under this Instrument, the Company shall, and shall use its reasonable best efforts to take such action as the Holder and the Company shall jointly agree in good faith to be necessary to permit the Holder to comply with such Regulatory Requirement; provided, that, no action shall be required to be taken by the Company that would (i) require the Company or any of its Subsidiaries to change its line of business or effect any transactions involving the Company or any of its Subsidiaries (including, but not limited to, any corporate reorganization); (ii) materially interfere or would reasonably be expected to materially interfere with any financing, acquisition, corporate reorganization, merger, tender offer or other significant transaction involving the Company; (iii) require the Company to obtain shareholder approval; (iv) require the Company or any of its Subsidiaries to re-incorporate under the laws of any other jurisdiction or to register pursuant to the rules or regulations of any regulatory agency; or (v) result in any adverse tax consequences to the Company or any of its Subsidiaries. The reasonable costs of taking such action, whether by the Company, any of its Subsidiaries, the Holder or otherwise, shall be borne in full by the Holder.

SECTION 10. Registration Rights.

(a) As soon as reasonably possible, but in any event, no later than twelve (12) calendar months following the Commencement Date (and subject to satisfaction of the Registration Conditions), the Company shall prepare and file a shelf registration statement with the Commission to permit the public resale of the Registrable Securities (the “Registration Statement”). The Registration Statement required to be filed with the Commission pursuant to this Section 10(a) shall be on Form F-3 or Form F-10, or, if neither Form F-3 nor Form F-10 is then available to the Company, on Form F-1, Form S-3, Form S-1 or such other form of registration statement as is then available to effect a registration for resale of the Registrable Securities, covering the Registrable Securities, and shall contain a prospectus in such form as to permit any the Holder to sell the Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect, or in the case of Form F-10, any similar provision under Canadian securities laws) at any time beginning on the effective date for such Registration Statement. The Company shall use its best efforts to cause a Registration Statement filed pursuant to this Section 10(a) to be declared effective by the Commission as soon as possible, but in any event, within one hundred twenty (120) calendar days after the filing of the Registration Statement. A Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holder, including by way of an underwritten offering, if so elected by the Holder, subject to a minimum offering size of $3,000,000. During the Effectiveness Period, the Company shall use its best efforts to cause a Registration Statement filed pursuant to this Section 10(a) to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another registration statement is available for the resale of the Registrable Securities until the Registration Termination Time. The Company shall prepare and file a listing application with the Principal Market for the Company’s Common Shares (including Nasdaq and TSX, if applicable, or such other national securities exchange on which the Company’s Common Shares are then listed and traded, in each case, to the extent required by the rules and regulations of such exchange) to list all Conversion Shares issuable upon exercise of the conversion rights under this Instrument covered by a Registration Statement and shall have such Conversion Shares issuable upon exercise of the conversion rights under this Instrument promptly approved for listing on such Principal Market (including Nasdaq and TSX, if applicable, or such other national securities exchange on which the Common Shares are then listed and traded, in each case, to the extent required by the rules and regulations of such exchange) by the effective date of such Registration Statement, subject only to official notice of issuance. Within two (2) Business Days of the effective date of a Registration Statement, the Company shall notify the Holder of the effectiveness of such Registration Statement.

10

(b) When effective, a Registration Statement (including the documents incorporated therein by reference) shall comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made).

(c) Without limiting Section 10(a), the Company agrees that it shall notify the Holder in writing at least five (5) Business Days prior to the filing of any registration statement under the Securities Act for purposes of a proposed public offering of Common Shares (including, without limitation, registration statements relating to secondary offerings of securities of the Company, but excluding (i) any registration statement relating to any employee benefit plan; (ii) with respect to any corporate reorganization or transaction under Rule 145 promulgated under the Securities Act, any registration statement related solely to the issuance or resale of securities issued in such a transaction; (iii) any registration statement related solely to Common Shares issued upon conversion of convertible debt securities; (iv) any registration statement filed under Rule 462(b) promulgated under the Securities Act; or (v) any registration statement on Form S-4, Form F-4 or Form S-8 not contemplated by clauses (i) through (iv) hereof) that would be filed at any time during which this Instrument is still outstanding and the Holder (together with the Holder’s Affiliates who are holders of the other conversion instruments forming the same series with this Instrument) continues to hold or beneficially own Registrable Securities that comprise at least one percent (1%) of the Common Shares then outstanding, and the Company will afford the Holder an opportunity to include in such registration statement all or part of the Registrable Securities, subject to the provisions hereof (such registration statement, the “Piggyback Registration Statement”). If the Holder desires to include in any such Piggyback Registration Statement all or any part of the Registrable Securities held by it, the Holder shall, within three (3) Business Days after the above-described notice from the Company, so notify the Company in writing and shall thereafter furnish the Company with such information as the Company reasonably requires to include such Registrable Securities in such offering; provided that, if such Registrable Securities represent Conversion Shares that have not yet been issued upon exercise of this Instrument, then the Holder shall also include a Notice of Conversion in respect of such Registrable Securities, it being understood that in no event shall the Company be obligated to include in any such Piggyback Registration Statement any Conversion Shares that have not been, or will not be, actually issued prior to the closing of the applicable offering due solely to the Holder’s failure to timely deliver such Notice of Conversion to the Company. The Company will use its commercially reasonable efforts to cause such Registrable Securities as to which inclusion shall have been so requested to be included in the Piggyback Registration Statement, subject to the second proviso in the next sentence. The Holder shall be entitled to sell the Registrable Securities included in a Piggyback Registration Statement in accordance with the method of distribution contemplated in the Piggyback Registration Statement; provided that, if the Piggyback Registration Statement relates to an underwritten offering, then (A) the Company shall be entitled to select the underwriters in its sole discretion and (B) the Holder must sell all Registrable Securities included on the Piggyback Registration Statement in such underwritten offering pursuant to an underwriting agreement containing terms and conditions that are customary for secondary offerings; and provided, further, that if the number of Registrable Securities requested by the Holder, together with the number of Common Shares that other persons that have duly requested to be included in such Piggyback Registration Statement pursuant to “piggyback rights” evidenced by another agreement (including, without limitation, the Existing Registration Rights Agreement) (collectively, “Requested Shares”), exceeds the maximum number of securities that may be sold in the applicable offering under such Piggyback Registration Statement without adversely affecting the success of such offering, as advised by the managing underwriters for such offering, then the number of Requested Shares to be included in such Piggyback Registration Statement will be allocated first, to such other persons party to the Existing Registration Rights Agreement; second, to the Holder; and third, to any other such persons. The Company may withdraw a Piggyback Registration Statement prior to its being declared effective without incurring any liability to the Holder and shall not be required to keep a Piggyback Registration Statement effective for longer than the period contemplated by the intended manner of distribution for the securities of the Company to be sold by the Company as described in the prospectus included in the Piggyback Registration Statement.

11

(d) For the avoidance of doubt, the rights to cause the Company to register Registrable Securities granted to the Holder by the Company under this Section 10 shall be fully assignable and transferrable to the same extent as this Instrument and the Conversion Shares are assignable and transferrable pursuant to Section 7 hereof, and any assignee or transferee of any Conversion Securities shall have all of the rights of the Holder to cause the Company to register Registrable Securities as set forth in this Section 10.

(e) The Holder (or any assignee or transferee) shall cooperate with the Company by, with reasonable promptness, supplying information and executing documents relating to such Holder (or transferee or assignee) or the securities of the Company owned by such Holder (or transferee or assignee) in connection with such registration under this Section 10 which are customary for offerings of this type or are required by applicable laws or regulations, including, but not limited to, furnishing to the Company a completed questionnaire in the form attached to this Instrument as Exhibit C. In the event the Holder does not comply with the immediately preceding sentence within a reasonable time prior to the initial filing in connection with such registration, the Company shall be permitted to exclude the Holder as a selling securityholder in connection therewith. In addition, the right of the Holder to include any of its Registrable Securities in any underwritten offering pursuant to a Piggyback Registration Statement will be subject to the execution and delivery by such Holder or its duly authorized representative or attorney-in-fact, of any related underwriting agreement and such other agreements or instruments (including customary “lock-up” agreements, custody agreements and powers of attorney), if any, as may be reasonably requested (to the same extent any such request is also made to the Company’s directors or officers and/or other selling shareholders in such offering) by the managing underwriters for such offering.

(f) Notwithstanding the foregoing provisions of this Section 10, the Company may, at any time, (i) delay the filing or delay or suspend the effectiveness of a Registration Statement, Piggyback Registration Statement or any pending or potential offering thereunder; (ii) without suspending such effectiveness, instruct the Holder not to sell any securities included in a Registration Statement or Piggyback Registration Statement; or (iii) delay the filing of any amendment or supplement to any Registration Statement or Piggyback Registration Statement, if, in the case of any of clause (i), (ii) or (iii), the Board has determined and promptly delivers a notice (a “Suspension Notice”) to the Holder in writing that in its reasonable good faith judgment (A) a material event has occurred or is likely to occur with respect to the Company that has not been publicly disclosed and, if disclosed, could reasonably be expected to materially and adversely affect the Company and its ability to consummate the registration of the resale of the Registrable Securities or (B) such registration could reasonably be expected to materially interfere with any material financing, acquisition, corporate reorganization, merger, tender offer or other significant transaction involving the Company (a “Suspension Period”), by providing the Holder with written notice of such Suspension Period and the reasons therefor. The Company will use its reasonable best efforts to provide such Suspension Notice at least ten (10) Business Days prior to the commencement of such a Suspension Period; provided, however, that in any event the Company will provide such notice no later than the commencement of such Suspension Period; provided, further, that in no event will a Suspension Period exceed thirty (30) days and in no event shall the total number of days subject to a Suspension Period during any consecutive twelve (12) month period exceed forty-five (45) days. Any Suspension Period will not be deemed to have ended until the Holder has received a notice from the Company stating that such Suspension Period has ended. The Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a Suspension Notice from the Company, such Holder will forthwith discontinue any offers and sales of such Registrable Securities under a Registration Statement or a Piggyback Registration Statement until such Holder’s receipt of the copies of the applicable supplemented prospectus and/or amended registration statement or until it is advised in writing by the Company that the use of the prospectus under the applicable Registration Statement or Piggyback Registration Statement, as applicable, may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such prospectus or amended registration statement. The Company and the Holder acknowledge and agree that in no way shall this Section 10(f) limit the Holder’s ability to sell securities without using a Registration Statement or a Piggyback Registration Statement.

12

(g) The Company shall pay all reasonable Registration Expenses.

SECTION 11. Representations and Warranties of the Company. The Company hereby represents and warrants to the Holder as of the Commencement Date, that:

No shareholder or equityholder approvals are required under the Organization Documents of the Company or any of its Subsidiaries, any instrument or agreement to which the Company or any of its Subsidiaries is a party, or under the rules of the Principal Market on which the Common Shares are traded (including Nasdaq and TSX, if applicable) in connection with the issuance of this Instrument or the Conversion Shares issuable upon exercise of the conversion rights under this Instrument.

(d) Neither the Company nor any of its Subsidiaries is insolvent or bankrupt or unable to pay its debts as they fall due and neither the Company nor any of its Subsidiaries has stopped or suspended payment of its debts or indicated its intention to do so, nor has any analogous procedure or step been taken or proposed in any jurisdiction in relation to the Company or any of its Subsidiaries, nor has the Company or any of its Subsidiaries commenced negotiations with one or more of its creditors with a view to rescheduling or restructuring any of its indebtedness. No steps have been taken or proposed for the winding-up, bankruptcy, administration, examinership, insolvency, dissolution or reorganization of the Company or any of its Subsidiaries.

(f) The Conversion Shares have been duly and validly authorized and reserved for issuance by the Company and, when issued upon exercise of the conversion rights under this Instrument in accordance with its terms, will be fully paid and nonassessable, and the issuance of the Conversion Shares, if any, will not be subject to any statutory or contractual preemptive right, right of first refusal or other similar rights; the Conversion Shares when issued and delivered against payment therefor as provided for in this Instrument will be free of any restriction upon the voting or transfer thereof pursuant to the Company’s Organization Documents or any agreement or other instrument to which the Company or any of its Subsidiaries is a party other than the restrictions on ownership and transfer set forth in the Company’s Organization Documents, if any, and applicable securities laws.

13

(g) The Conversion Shares issuable upon exercise of the conversion rights under this Instrument will conform, in all material respects to the descriptions thereof contained in the reports, schedules, forms, statements and other documents required to be filed by the Company under the Securities Act, the Exchange Act and applicable Canadian securities laws (the foregoing materials, including the exhibits thereto and documents incorporated by reference therein, being collectively referred to herein as the “Public Filings”) and the Organization Documents of the Company. Except as disclosed in the Public Filings, there are no persons with registration or other similar rights to have any equity or debt securities, including securities which are convertible into or exchangeable for equity securities, registered pursuant to any registration statement or otherwise registered by the Company or any of its Subsidiaries under the Securities Act or applicable Canadian securities laws, all of which registration or similar rights are fairly summarized in the Public Filings.

(h) Assuming the accuracy of the representations made by the Holder herein as of the Commencement Date and as of the date of any exercise of such Holder’s conversion rights under this Instrument, as applicable, the offer and sale by the Company of this Instrument to the Holder and the Conversion Shares issuable upon exercise by the Holder of the conversion rights under this Instrument are not required to be registered pursuant to the provisions of Section 5 of the Securities Act, and the first trade in the Conversion Shares issuable upon exercise by the Holder of the conversion rights under this Instrument is exempt from the prospectus requirements of applicable Canadian securities laws, provided that the trade is not a “control distribution” (as such term is defined in National Instrument 45-102 – Resale of Securities).

SECTION 12. Representations and Warranties of the Holder. The Holder hereby represents and warrants to the Company as of the Commencement Date and on each date that any Notice of Conversion is delivered to the Company that the Holder (a) is an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act, (b) is aware that the prospective investment in this Instrument and the Conversion Shares issuable upon exercise of the conversion rights under this Instrument, may involve a high degree of risk, and has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of such investment, (c) can bear the economic risks of its investment in this Instrument and the Conversion Shares issuable upon conversion hereunder, and (d) has had (i) access to representatives of the Company during the course of this transaction, prior to the creation of this Instrument and, if applicable, prior to the exercise of the conversion rights under this Instrument, (ii) the opportunity to ask questions of and receive answers from the Company and its representatives concerning the terms and conditions of this Instrument and the Conversion Shares, and (iii) the opportunity to obtain any additional information necessary to verify the information related to this Instrument, the Conversion Shares or otherwise to the business and proposed activities of the Company. In addition, the Holder is acquiring this Instrument, and any Conversion Shares issuable upon exercise of the conversion rights hereunder, solely for its own account, and such Instrument is being and will be acquired by such Holder solely for the purpose of investment and not with a view to resale of this Instrument (or any Conversion Shares issuable upon conversion hereunder) in connection with a distribution thereof in violation of the Securities Act. The Holder understands and acknowledges that this Instrument, and any Conversion Shares issuable upon conversion hereunder, may not be transferred or sold except pursuant to (A) the registration or qualification provisions of applicable securities laws or pursuant to an available exemption therefrom and (B) the terms of this Instrument. The Holder is not a resident of Canada and is investing in this Instrument as principal for its own account, not for the benefit of any other person, for investment only and not with a view to the resale or distribution of all or any of this Instrument or the Conversion Shares.

PROCEDURES FOR ISSUANCE OF CONVERSION SHARES UPON EXERCISE

The procedures, rights and obligations set forth in this Exhibit B shall apply to the issuance and settlement of Conversion Shares pursuant to any Notice of Conversion delivered by the Holder or any Automatic Exercise, as applicable, pursuant to the attached Instrument, unless the Cash Settlement Amount is paid or proposed to be paid in accordance with Section 2(d) of the attached Instrument. Capitalized terms used but not otherwise defined herein have the meanings ascribed thereto in the attached Instrument.

(a) (x) Unless otherwise designated by the Holder in the applicable Notice of Conversion, on or before the fifth (5^th) Trading Day following the date on which the Company has received such Notice of Conversion; provided, that, such date shall be extended by up to five (5) Trading Days in the event the Company is required to adjust the Conversion Price in accordance with Section 5 of the attached Instrument, or (y) following any Automatic Exercise, on the Expiration Date (as applicable, the “Share Delivery Date”), the Company shall:

(i) if (A) there is an effective registration statement filed pursuant to the Securities Act covering the resale of such Conversion Shares by the Holder and (B) it is not otherwise deemed necessary under applicable securities laws for a restrictive legend to be affixed on such Conversion Shares upon issuance to the Holder, and, in each case, the Transfer Agent is participating in The Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program (“FAST”), upon the request of the Holder, credit such aggregate number of Conversion Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system; or

(ii) if (A) there is no effective registration statement filed pursuant to the Securities Act covering the resale of such Conversion Shares by the Holder, (B) it is deemed necessary under applicable securities laws for a restrictive legend to be affixed on such Conversion Shares upon issuance to the Holder, and/or (C) if the Transfer Agent is not then participating in the DTC’s FAST, upon the request of the Holder, issue and deliver (via reputable overnight courier) to the address as specified in the Notice of Conversion (or, in the case of an Automatic Exercise, to any address specified by the Holder in writing), a Direct Registration System statement, registered in the name of the Holder or its designee, for the number of Conversion Shares to which the Holder shall be entitled pursuant to such exercise, and if applicable, including a restrictive legend thereon.

If any restrictive legend is placed on Conversion Shares, the Company agrees that, as promptly as practicable following the Legend Removal Date (as defined below) in respect of such Conversion Shares, it will, subject to receipt of such representations and covenants of the Holder and the Holder’s executing broker, if any, as the Company or the Transfer Agent may reasonably require in connection therewith, deliver or cause to be delivered to the Holder a book entry position representing such Conversion Shares that is free from any restrictive legend (and the Company shall cause to be issued any legal opinion required by the Transfer Agent with respect thereto). The Company shall not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this section, except as may be required under applicable securities laws. To the extent that book entry positions are issued representing the Conversion Shares, such book entry positions subject to legend removal hereunder shall be delivered by the Transfer Agent to the Holder by issuing to the Holder by electronic delivery at the applicable balance account at DTC, the Transfer Agent or any custodian of the Holder, as applicable, at the Holder’s election. Any fees (with respect to the Transfer Agent, the Company’s counsel or otherwise) associated with the issuance of such opinion or the removal of such legend shall be borne by the Company. “Legend Removal Date”, in respect of any Conversion Shares, means the earliest of the date that (A) the

Company has received appropriate notice from the Holder that such Conversion Shares have been or are being sold or transferred pursuant to an effective registration statement under the Securities Act, (B) the Company has received appropriate notice from the Holder that such Conversion Shares have been or are being sold or transferred pursuant to Rule 144 (if the transferor is not an affiliate of the Company); or (C) the Company has received appropriate notice from the Holder that such Conversion Shares are eligible for resale under Rule 144 without volume or manner-of-sale restrictions.

(b) Upon delivery of a Notice of Conversion or any Automatic Exercise, as applicable, the Holder shall be deemed to have become the registered legal and beneficial owner of the Conversion Shares with respect to which the conversion rights under this Instrument have been exercised, irrespective of the date such Conversion Shares are credited to the Holder’s DTC account or the date of delivery of the certificate(s) evidencing such Conversion Shares (as the case may be). If the attached Instrument is submitted in connection with any exercise of the conversion rights pursuant to Section 2(e) of the attached Instrument and the Maximum Conversion Amount then available for conversion into Conversion Shares is greater than the Aggregate Conversion Amount being converted into Conversion Shares upon such exercise, then, at the request of the Holder, the Company shall as soon as practicable and in no event later than two (2) Business Days after the date of settlement pursuant to Section 2(e) of the attached Instrument and, at its own expense, issue and deliver to the Holder (or its designee) a new conversion instrument representing the right to convert the newly calculated maximum amount, after giving effect to such exercise, of the Outstanding Amount of Loans owing to the Holder for subscription for Conversion Shares (such newly calculated maximum amount being an amount equal to (i) the Maximum Conversion Amount which was available for conversion immediately prior to such exercise, minus (ii) the Aggregate Conversion Amount for such exercise).

(c) The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation, fees and expenses of the Transfer Agent) that may be payable with respect to the issuance of Conversion Shares upon exercise of the conversion rights under the attached Instrument (but not any subsequent transfer of Conversion Shares so issued).

(d) Notwithstanding any other provision in this Agreement, the Holder may elect, at its sole discretion, to receive unregistered Conversion Shares issued in response to a Notice of Conversion or any Automatic Exercise instead of Conversion Shares registered pursuant to any registration statement filed with the Commission to register the Conversion Shares. In such case, the Holder agrees and acknowledges that any such unregistered Conversion Shares shall bear a securities law legend substantially similar to the legend on the facing page of the attached Instrument, to the extent required by applicable securities laws.

SECOND AMENDED AND RESTATED COMMON SHARE CONVERSION INSTRUMENT

Amended and Restated: December 30, 2023

Date of Issuance: July 14, 2022

Series No. 2022-A

Certificate No. 3

THIS IS TO CERTIFY that Madryn Select Opportunities, LP and its transferees, successors and assigns (the “Holder”) shall have the right (but not the obligation) to convert the Outstanding Amount of Loans owing to the Holder under the Credit Agreement, up to the Maximum Conversion Amount then available, into common shares, without par value (the “Common Shares”) in the capital of Greenbrook TMS Inc., a corporation incorporated under the laws of the Province of Ontario (the “Company”), at the initial conversion price of $1.90 per Common Share (the “Conversion Price”), at any time after the date of issuance listed above (the “Commencement Date”) and expiring on the Expiration Date. This Second Amended and Restated Common Share Conversion Instrument (this “Instrument”) is issued subject to the Organization Documents of the Company and under and pursuant to that certain Credit Agreement, dated as of July 14, 2022, by and among the Company, the Holder, and the other parties thereto (as amended, modified or supplemented from time to time, the “Credit Agreement”). Capitalized terms used herein shall have the meanings ascribed to such terms in Section 13 hereof unless otherwise defined herein.

This Instrument amends, restates and replaces in its entirety that certain First Amended and Restated Common Share Conversion Instrument dated as of December 4, 2023, issued by the Company to the Holder.

SECTION 1. The Instrument; Transfer and Exchange.

(a) The Instrument. This Instrument and the rights and privileges of the Holder hereunder may be exercised in whole or in part as provided herein and, as more fully set forth in Section 1(b) and Section 7 hereof, may, subject to applicable securities laws and the terms of this Instrument, be transferred by the Holder to any other Person or Persons who meet the requirements set forth herein at any time or from time to time, in whole or in part.

(b) Transfer and Exchanges. The Company shall initially record this Instrument in a register maintained by the Company for that purpose and subject to Section 7 hereof, from time to time thereafter shall reflect the transfer of this Instrument on such register when surrendered for transfer in accordance with the terms hereof and properly endorsed, accompanied by appropriate instructions, and further accompanied by payment in cash or by check, bank draft or money order payable to the order of the Company, in United States currency, of

an amount equal to any stamp or other tax or governmental charge or fee required to be paid in connection with the transfer thereof. Upon any such transfer, a new conversion instrument or conversion instruments shall be issued to and in the name of the transferee and the Holder (in the event this Instrument is only partially transferred or in connection with any concurrent partial transfer and partial exercise) and the surrendered conversion instrument shall be canceled and the Company shall update the register accordingly. This Instrument may be exchanged at the option of the Holder, when surrendered at the Principal Office of the Company, for another conversion instrument or other conversion instruments of like tenor and representing in the aggregate the right to convert a like amount of the Outstanding Amount of Loans owing to the Holder under the Credit Agreement, up to the Maximum Conversion Amount then available, into a like number of Common Shares at the Conversion Price (as such number may be adjusted upon adjustment of the Conversion Price as provided in Section 5).

SECTION 2. Exercise.

(a) Right to Exercise. At any time after the Commencement Date and on or before the Expiration Date, the Holder, in accordance with applicable securities laws and the terms hereof, shall be entitled to exercise the conversion rights under this Instrument, in whole at any time or in part from time to time, by delivering this Instrument to the Company during normal business hours on any Business Day at the Company’s Principal Office, together with the Notice of Conversion (with a copy to the Administrative Agent), in the form attached hereto as Exhibit A and made a part hereof (the “Notice of Conversion”), duly executed. The Holder shall not be required to deliver the original of this Instrument in order to effect an exercise hereunder. Subject to Section 2(c), the aggregate number of Conversion Shares to be subscribed for by the Holder pursuant to the applicable Notice of Conversion shall be equal to the amount calculated by dividing (i) the Aggregate Conversion Amount by (ii) the Conversion Price then in effect.

(b) Conversion of the Aggregate Conversion Amount. For any exercise, in whole or in part, of the conversion rights under this Instrument, payment of the Aggregate Conversion Amount shall be made to the Company by (i) automatically reducing the Outstanding Amount of the Loans owing to the Holder under the Credit Agreement by an amount equal to the Aggregate Conversion Amount or (ii) a Net Exercise as provided in Section 2(c). Other than in the case of a Net Exercise in accordance with Section 2(c), simultaneously with the allotment and issuance of Conversion Shares, or the payment of the applicable Cash Settlement Amount, as the case may be, pursuant to Section 2(e), the Outstanding Amount of the Loans in an amount equal to the Aggregate Conversion Amount shall be deemed repaid under the Credit Agreement in accordance with Section 2.14 thereof. Following any exercise, in whole or in part, of the conversion rights under this Instrument, the Maximum Conversion Amount available for any subsequent exercise of the conversion rights under this Instrument shall be reduced by the Aggregate Conversion Amount paid by the Holder in connection with such exercise.

(c) Net Exercise. The Holder shall have the right to pay all or a portion of the Aggregate Conversion Amount by making a net exercise (“Net Exercise”), in which case the portion of the Aggregate Conversion Amount to be so paid shall be paid by reducing the number of Conversion Shares otherwise issuable pursuant to the Notice of Exercise by an amount equal to (i) the Aggregate Conversion Amount to be so paid, divided by (ii) the Fair Market Value Per Common Share. For the avoidance of doubt, in the case of a Net Exercise by the Holder, no amount of the Outstanding Amount of the Loans owing to the Holder under the Credit Agreement shall be reduced or deemed repaid.

(d) Cash Settlement.

(i) Notwithstanding any other provision of this Instrument, if, following the exercise of the conversion rights under this Instrument, (A) the applicable rules of the Toronto Stock Exchange (“TSX”) or The Nasdaq Stock Market LLC (“Nasdaq”) require approval by TSX or Nasdaq, as applicable, for any allotment or issuance of any number of Conversion Shares by the Company with respect to all or any portion of the Aggregate Conversion Amount, and the Company is unable to obtain such approval by using commercially reasonable efforts, (B) on or prior to the Share Delivery Date, the Company makes a written request to satisfy its obligations under this Instrument by means other than such allotment and

2

issuance of such number of Conversion Shares, and the Holder, in its sole and absolute discretion, accepts such request, or (C) the Company fails for any reason to allot and issue the applicable number of Conversion Shares with respect to all or any portion of the Aggregate Conversion Amount on or prior to the Share Delivery Date, and the Holder, in its sole and absolute discretion, elects to require the Company to satisfy its obligations under this Instrument by means other than such allotment and issuance of such applicable number of Conversion Shares (any such portion of the Aggregate Conversion Amount referred to in Section 2(d)(i)(A), (B) or (C), the “Non-Share Settled Portion”), then, in each case, the Company shall, in lieu of allotting and issuing to the Holder the applicable number of Conversion Shares with respect to the Non-Share Settled Portion, pay the applicable Cash Settlement Amount to the Holder for such Non-Share Settled Portion. Notwithstanding the foregoing, in the case of any Automatic Exercise pursuant to Section 2(i), the Company shall not be permitted to satisfy its obligations under this Instrument by means of payment of the applicable Cash Settlement Amount to the Holder, other than payment of the Cash Settlement Amount for the Non-Share Settled Portion referred to in Section 2(d)(i)(A).

(ii) The cash settlement amount (the “Cash Settlement Amount”) for any Non-Share Settled Portion shall be calculated as of the date of exercise of this Instrument and shall be equal to the product of (A) the Fair Market Value Per Common Share, multiplied by (B) the number of Conversion Shares which would, but for the occurrence of any event referred to in Section 2(d)(i)(A), (B) or (C), have been issuable to the Holder upon exercise of the conversion rights under this Instrument with respect to such Non-Share Settled Portion.

(iii) The Company shall be required to pay any Cash Settlement Amount to the Holder on or before the following applicable date (each, a “Cash Settlement Date”): (A) if such payment is required under Section 2(d)(i)(A), the Share Delivery Date; (B) if such payment is required under Section 2(d)(i)(B), the fifth (5^th) Business Day following the date of the Holder’s acceptance of the written request of the Company referred to in Section 2(d)(i)(B); or (C) if such payment is required under Section 2(d)(i)(C), the third (3^rd) Business Day following the date of the Holder’s election referred to Section 2(d)(i)(C). Notwithstanding the foregoing, the Cash Settlement Date (other than the Cash Settlement Date in connection with any Cash Settlement Amount to be paid upon any Automatic Exercise) shall be extended by up to five (5) Business Days in the event the Company is required to adjust the Conversion Price in accordance with Section 5.

(iv) The Company covenants and agrees that, after the date of issuance set forth above, it shall not, without the prior written consent of the Holder, enter into or agree to become subject to specific or direct contractual term, condition, provision or agreement that would specifically prohibit the performance of the Company’s obligations to pay the applicable Cash Settlement Amount under this Section 2(d).

(e) Issuance of Conversion Shares or Payment of Cash Settlement Amount Upon Exercise. Upon (x) receipt by the Company of a Notice of Conversion at its Principal Office in proper form for exercise or (y) any Net Exercise as provided in Section 2(c) or any Automatic Exercise as provided in Section 2(i), the Company shall:

(i) allot and issue to the Holder, without delay and in any case on or prior to the Share Delivery Date, the number of Conversion Shares specified in the Notice of Conversion as set forth in Exhibit B hereto; or

(ii) if applicable, pay to the Holder the applicable Cash Settlement Amount in accordance with Section 2(d),

and, in each case, simultaneously deliver to the Holder, without duplication, all Distributed Property that the Holder is entitled to receive pursuant to Section 5(a)(ii).

3

(f) Fractional Shares. If any fraction of a Conversion Share would be deliverable upon an exercise of this Instrument, the Company may, in lieu of delivering such fraction of a Conversion Share, make a cash payment to the Holder in an amount equal to the same fraction of the Fair Market Value Per Common Share determined as of the date of exercise of this Instrument.

(g) Partial Exercise. In the event that the Holder exercises this Instrument in part from time to time, there shall be no restriction on the number of times the Holder may exercise its conversion rights under this Instrument to subscribe for Conversion Shares or the minimum number of Conversion Shares that the Holder shall be required to subscribe for upon any partial exercise of its conversion rights under this Instrument. Upon any partial exercise of this Instrument, the Company shall issue and deliver to the Holder a new conversion instrument in like form for the unexercised portion thereof which has not expired.

(h) Common Shares. The Common Shares issued pursuant to this Instrument shall:

(i) rank equally in all respects from the effective date of issue with the Common Shares then in issue (if any);

(ii) be entitled to all dividends and distributions declared or paid on any date or by reference to any date on or after the date on which the relevant Notice of Conversion is delivered to the Principal Office (or at such other address as the Company may designate by notice in writing to the Holder in accordance with the terms hereof); and

(iii) otherwise have the rights and privileges under applicable law and as prescribed in the Organization Documents of the Company from time to time.

(i) Automatic Exercise. Unless the Holder has expressly notified the Company in writing at least five (5) Business Days prior to the Expiration Date that such Holder either (a) elects not to exercise the conversion rights under this Instrument and that such Holder will instead let this Instrument expire on the Expiration Date or (b) will exercise the conversion rights under this Instrument on or prior to the Expiration Date by a method other than as set forth in this Section 2(i), if the Fair Market Value Per Common Share determined as of the Expiration Date is greater than the Conversion Price then in effect, the Holder shall be deemed, without further act by the Holder (and, for avoidance of doubt, without any delivery of this Instrument or the Notice of Conversion to the Company), for all purposes of this Instrument, to have automatically exercised in full, by a Net Exercise in accordance with Section 2(c), its conversion rights under this Instrument on the Expiration Date (an “Automatic Exercise”). If the Expiration Date is expected to occur pursuant to clause (b) of the definition thereof, the Company shall deliver the Holder a written notice of such expected occurrence of such Expiration Date at least ten (10) Business Days prior to such expected occurrence of such Expiration Date with the view to allowing the Holder sufficient time to opt out of any Automatic Exercise on such expected Expiration Date.

(j) Company’s Failure to Timely Deliver Securities or Pay Cash Settlement Amount.

(i) The Company understands that a delay in the delivery of the Conversion Shares after the Share Delivery Date or payment of the Cash Settlement Amount after the applicable Cash Settlement Date could result in economic loss to the Holder. As compensation to the Holder for such loss, if the Company fails to (A) cause the Transfer Agent to transmit to the Holder the Conversion Shares on or before the Share Delivery Date in accordance with the provisions of Exhibit B pursuant to an exercise of the conversion rights under this Instrument (other than a failure caused by incorrect or incomplete information provided by the Holder to the Company) or (B) pay the Cash Settlement Amount to the Holder on or before the applicable Cash Settlement Date, the Company agrees to pay (as liquidated damages and not as a penalty) to the Holder for late issuance of the Conversion Shares the proportionate amount of $100 per Trading Day (increasing to $200 per Trading Day after the tenth (10^th) Trading Day) after the Share Delivery Date or the applicable Cash Settlement Date, as applicable, for each $10,000 of Aggregate Conversion Amount for which the conversion rights under this Instrument is exercised which are not timely delivered or paid, respectively. Notwithstanding anything to the contrary contained in this Instrument, the Company shall not be required to pay any amounts under this Section 2(j) during the first five (5) Trading Days of any late issuance or delivery of Conversion Shares or Cash Settlement Amounts, as applicable, in connection with an Automatic Exercise.

4

(ii) Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Conversion Shares upon exercise of the conversion rights under this Instrument. The Company shall pay any payments incurred under this Section 2(j) in immediately available funds upon demand.

(k) Securities Law Legend(s). The Holder agrees and acknowledges, by receipt of this Instrument, that this Instrument, and any Conversion Shares issuable upon conversion hereof, shall bear a securities law legend substantially similar to the legend on the facing page of this Instrument, to the extent required by applicable securities laws. The Company acknowledges and agrees that Conversion Shares issuable upon exercise of the conversion rights under this Instrument shall not be required to contain any legend while a registration statement (including the Registration Statement) covering the resale of such Conversion Shares is effective under the Securities Act.

(l) Administrative Agent’s Acknowledgement. The Administrative Agent acknowledges the terms of this Instrument and agrees that, upon exercise of the conversion rights under this Instrument, the Administrative Agent shall perform its duties and exercise its rights and powers under the Credit Agreement, including, without limitation, in accordance with the terms of Section 2.14 thereof, to give effect to any corresponding deemed repayment of the Outstanding Amount of Loans under the Credit Agreement in an amount equal to the Aggregate Conversion Amount.

SECTION 3. Payment of Taxes. The Company shall promptly pay any and all stamp, documentary, registration or similar tax or taxes in connection with the entry into, performance, enforcement or admissibility in evidence of this Instrument or attributable to the initial issuance of Conversion Shares or other securities issuable upon the exercise of the conversion rights under this Instrument or issuable pursuant to Section 5 hereof, excluding any tax or taxes which may be payable because of the transfer involved in the issuance or delivery of any certificates for Conversion Shares or other securities in a name other than that of the Holder in respect of which such Conversion Shares or securities are issued. Any and all payments by or on account of any obligation of the Company hereunder (whether paid in cash or otherwise) shall be made free and clear of and without deduction or withholding for any taxes except as required by applicable law; provided that, if the Company is required to deduct or withhold any taxes hereunder then (a) the amount payable shall be increased as necessary so that, after making all required deductions or withholdings (including deductions or withholdings applicable to additional amounts payable under this Section 3), the Holder receives an amount (in cash or otherwise) equal to the amount it would have received had no such deduction or withholding been made; provided, that no gross-up shall be required in respect of Day 1 U.S. Federal Withholding Taxes, (b) the Company shall make such required deduction or withholding, and (c) the Company shall pay to the relevant taxation authority the full amount deducted or withheld in accordance with, and within the time limits prescribed by, applicable law. The Company shall provide the Holder with copies of receipts or other communications relating to the remittance of such withheld amount or the filing of such forms received from such taxation authority promptly after receipt thereof. The Company shall indemnify the Holder, within ten (10) days after written demand therefor, for the full amount of any taxes (other than taxes computed by reference to net income of the Holder) paid or payable by the Holder, on or with respect to any payment (whether paid in cash or otherwise) by or on account of any obligation of the Company hereunder (including taxes (other than taxes computed by reference to net income of the Holder) imposed or asserted on or attributable to amounts payable under this Section 3) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such taxes were correctly or legally imposed or asserted by the relevant taxation authority.

5

SECTION 4. Replacement Instrument. In case this Instrument is mutilated, lost, stolen or destroyed, the Company shall issue and deliver in exchange and substitution for and upon cancellation of the mutilated Instrument, or in lieu of and in substitution for the Instrument lost, stolen or destroyed, a new Instrument of like tenor and representing an equivalent right or interest, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of such Instrument and upon receipt of indemnity reasonably satisfactory to the Company; provided, that if the Holder is a financial institution, business development company or other institutional or fund investor, its own agreement shall be satisfactory.

SECTION 5. Adjustments to the Conversion Price.

Under certain conditions, the Conversion Price is subject to adjustment as set forth in this Section 5.

(a) Adjustments. The Conversion Price, after taking into consideration any prior adjustments pursuant to this Section 5, shall be subject to adjustment from time to time as follows and, thereafter, as adjusted, shall be deemed to be the then applicable Conversion Price hereunder, subject to further adjustment.

(i) Common Share Distributions. Subdivisions and Combinations. In case at any time or from time to time the Company shall:

(A) issue to the holders of its Common Shares a dividend payable in, or other distribution of, Common Shares, bonus shares or other Equity Interests of the Company (a “Share Distribution”),

(B) subdivide its issued Common Shares into a larger number of Common Shares, including without limitation, by means of a stock split (a “Share Subdivision”), or

(C) combine its issued Common Shares into a smaller number of Common Shares (a “Share Combination”),

then the Conversion Price shall be (x) proportionately decreased in the case of a Share Distribution or a Share Subdivision and (y) proportionately increased in the case of a Share Combination. In the event the Company shall declare or pay, without consideration, any dividend on the Common Shares payable in any right to acquire Common Shares for no consideration, then the Company shall be deemed to have made a Share Distribution in an amount of Common Shares equal to the maximum number of Common Shares issuable upon exercise of such rights to acquire Common Shares. Any adjustment under this Section 5(a) shall become effective at the close of business on the date the Share Subdivision or Share Combination becomes effective, or upon the making of any Share Distribution.

(ii) Distributions. If the Company, at any time while this Instrument is outstanding, distributes to all holders of Common Shares for no consideration (A) evidence of its indebtedness, (B) any security (other than a Share Distribution), (C) rights or warrants to subscribe for or purchase any security (other than any deemed Share Distribution referred to in Section 5(a)(i)), or (D) any other asset, including cash or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction (in each case, “Distributed Property”), then, upon any exercise of the conversion rights under this Instrument that occurs after the record date fixed for determination of shareholders entitled to receive such distribution, the Holder shall be entitled to receive, in addition to the Conversion Shares otherwise issuable upon such exercise (if applicable), the Distributed Property that such Holder would have been entitled to receive in respect of such number of Conversion Shares had the Holder been the record holder of such Conversion Shares in respect of the then-unexercised portion of this Instrument immediately prior to such record date without regard to any limitation on exercise contained therein.

6

(b) Fundamental Transactions. If, at any time while this Instrument is outstanding, the Company effects a Fundamental Transaction, then, to the extent then permitted under applicable laws, rules and regulations (including the rules of the Principal Market (or such other national securities exchange on which the Common Shares are then listed and traded), upon any subsequent exercise of the conversion rights under this Instrument, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash, assets or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Conversion Shares then issuable upon exercise in full of the conversion rights under this Instrument without regard to any limitations on exercise contained herein, subject to adjustments from and after the consummation date as nearly equivalent as possible to the adjustments provided for in this Section 5 (the “Alternate Consideration”). The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the consummation thereof, any successor to the Company or surviving entity shall have (i) assumed, by written instrument delivered to the Holder, the obligation to deliver to the Holder, such Alternate Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to receive, and the other obligations under this Instrument, and (ii) delivered to the Holder an opinion of counsel for such corporation or entity, satisfactory to the Holder, which opinion shall state that all of the terms of this Instrument applicable in respect of such Alternative Consideration shall be enforceable against the Company and such successor or surviving entity in accordance with the terms hereof and thereof, together with such other matters as the Holder may reasonably request. In any such case, appropriate provisions shall be made with respect to the rights and interest of the Holder so that the provisions hereof shall thereafter be applicable with respect to such Alternate Consideration deliverable upon exercise of the conversion rights hereunder, and appropriate equitable adjustments shall be made to the Conversion Price payable hereunder; provided that the Maximum Conversion Amount shall remain the same (and, for the avoidance of doubt, this Instrument shall be exclusively exercisable for such Alternate Consideration from and after the consummation of such Fundamental Transaction). The provisions of this Section 5(b) shall similarly apply to subsequent transactions analogous to a Fundamental Transaction.

(c) Notices.

(i) Notice of Proposed Actions. The Company shall give to the Holder advance written notice of any proposed action by the Company or any of its Subsidiaries pursuant to which an adjustment to the Conversion Price may occur pursuant to this Section 5 as promptly as practicable and in any event within five (5) Business Days after the approval of such action or entry into any agreement to give effective to such action, which written notice shall specify the proposed date on which a record is to be taken for the purposes of any Share Distribution or distribution of any Distributed Property, or the proposed date on which any reclassification, reorganization, consolidation, merger, stock exchange, sale, transfer, disposition, liquidation, dissolution, winding up, Fundamental Transaction or other transaction is to take place and the date of participation therein by the holders of Common Shares of the Company, if any such date is to be fixed, or the proposed date on which the transfer of Common Shares is to occur, and shall also set forth such facts with respect thereto as shall be necessary to indicate the effect of such action on the Common Shares and on the Conversion Price after giving effect to any adjustment which will be required as a result of such action.

(ii) Adjustment Notice. Whenever the Conversion Price is to be adjusted pursuant to this Section 5, unless otherwise agreed by the Holder, the Company shall promptly (and in any event within five (5) Business Days after the event requiring the adjustment) prepare and deliver to the Holder a certificate signed by the chief financial officer of the Company, setting forth, in reasonable detail, the event requiring the adjustment and the method by which such adjustment is to be calculated. The certificate shall set forth, if applicable, a description of the basis on which the Board in good faith determined, as applicable, the equitable nature of any adjustment under Section 5(b) hereof and the new Conversion Price, as applicable.

7

SECTION 6. No Dilution or Impairment. The Company will not, by amendment of its Organization Documents or through any reorganization, recapitalization, transfer of assets, consolidation, merger, share exchange, dissolution or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Instrument, including, without limitation, the adjustments required under Section 5 hereof, if any, and will at all times in good faith assist in the carrying out of all such terms and in taking of all such action as may be necessary or appropriate to protect the rights of the Holder against dilution or other impairment, subject to compliance with applicable securities laws and stock exchange rules and regulations. Without limiting the generality of the foregoing and notwithstanding any other provision of this Instrument to the contrary (including by way of implication), the Company will take all such action as may be necessary or appropriate so that the Company may validly and legally issue Conversion Shares to the Holder upon the exercise of the conversion rights under this Instrument.

SECTION 7. Transfers of this Instrument.

(a) Generally. Subject to the restrictions set forth in this Section 7, the Holder may, at any time and from time to time, assign or transfer this Instrument and the Conversion Shares, in each case in whole or in part, without the prior written consent of the Company. The transferor shall be deemed to remain the holder of this Instrument until the name of the transferee is entered in the Company register in respect of this Instrument. This Instrument has not been, and the Conversion Shares at the time of their issuance may not be, registered under the Securities Act or qualified or registered under any applicable Canadian securities laws. Accordingly, the Company’s obligation to issue Conversion Shares upon exercise of this Instrument by any such transferee shall be subject to compliance with applicable securities laws, and the Company reserves the right to obtain such information from the transferee as it may reasonably request to confirm the applicability of an available exemption from registration or qualification under applicable securities laws, including, without limitation, confirmation of representations and warranties substantially similar to those set forth in Section 12. This Instrument and the Conversion Shares are issued or issuable subject to the provisions and conditions contained herein and in the Credit Agreement and to the provisions and conditions contained in the Organization Documents of the Company, and the Holder by accepting the same agrees with the Company to such provisions and conditions, and represents to the Company that this Instrument has been acquired and the Conversion Shares will be acquired for the account of the Holder for investment and not with a view to or for sale in connection with any distribution thereof.

(b) Compliance with Securities Laws. The Holder agrees that this Instrument and the Conversion Shares may not be sold or otherwise disposed of except pursuant to (i) an effective registration statement under the Securities Act covering the re-sale by the Holder of the Conversion Shares, and applicable U.S. state securities laws or pursuant to an applicable exemption from the registration requirements of the Securities Act and such U.S. state securities laws, and (ii) a prospectus filed under applicable Canadian securities laws covering the sale by the Holder of the Conversion Shares or pursuant to an applicable exemption from such Canadian securities law requirements.

(c) No Transfer to Non-Lenders. The Holder agrees that this Instrument may not be assigned, transferred or sold to any Person who is not a Lender under the Credit Agreement.

SECTION 8. Confidentiality. The Holder hereby agrees to comply with and be bound by, and agrees to require a transferee permitted hereby to be bound by, the confidentiality provisions in Section 11.07 of the Credit Agreement and acknowledges and agrees that (a) any information provided to the Holder or its representatives pursuant to this Instrument, (b) any other information provided to the Holder or its representatives that a reasonable person would deem to be confidential under the circumstances, and (c) any other information provided to the Holder or its representatives pursuant to this Instrument and is clearly identified at the time of delivery as confidential shall, in each case, be deemed Information (as defined in the Credit Agreement) and subject to the confidentiality provisions in Section 11.07 of the Credit Agreement.

8

SECTION 9. Covenants. The Company hereby covenants and undertakes to the Holder that for so long as the Holder holds this Instrument, any interest created under this Instrument or any Conversion Shares:

(a) Validly Issued Shares. All Conversion Shares issuable upon exercise of the conversion rights under this Instrument and full conversion of the Aggregate Conversion Amount (including those issued pursuant to adjustments as required pursuant to Section 5 hereof) shall, upon delivery by the Company, be duly authorized and validly issued, fully paid and nonassessable, free from all stamp taxes, liens and charges with respect to the issue or delivery thereof and otherwise free of all other security interests, encumbrances and claims (other than security interests, encumbrances and claims to which the Holder is subject prior to or upon the issuance of the applicable Conversion Shares or pursuant to the Credit Agreement, restrictions under applicable federal, provincial, territorial and/or state securities laws and other transfer restrictions described herein).

(b) Reservation of Shares. The Company shall at all times reserve and keep available for issue out of the aggregate of its authorized but unissued share capital, free of preemptive rights, such number of its duly authorized Common Shares as shall be required to enable the Company to issue Conversion Shares in the full amount required upon exercise in full of the conversion rights under this Instrument. If any Common Shares reserved or to be reserved for the purpose of the exercise of the conversion rights under this Instrument, or any shares or other securities reserved or to be reserved for the purpose of issuance pursuant to Section 5 hereof, require registration with or approval of any Governmental Authority under any federal or state law (other than securities laws) before such shares or other securities may be validly delivered upon exercise of the conversion rights under this Instrument, then the Company covenants that it will, at its sole expense, promptly secure such registration or approval, as the case may be (including, but not limited to, approvals or expirations of waiting periods required under the Hart Scott Rodino Antitrust Improvements Act).

(c) No Effect Upon Lending Relationship. Notwithstanding anything herein to the contrary, nothing contained in this Instrument shall affect, limit or impair the rights and remedies of the Holder or any of its Affiliates in its capacity as a lender to the Company pursuant to any agreement under which the Company has borrowed money from the Holder or any of its Affiliates. Without limiting the generality of the foregoing, the Holder, for itself or in any capacity with respect to any of its Affiliates in exercising its or its Affiliates’ respective rights as a lender, including making its decision on whether to foreclose on any collateral security, will have no duty to consider (i) its status or the status of any of its Affiliates as a direct or indirect equity holder of the Company, (ii) the equity of the Company or (iii) any duty it may have to any other direct or indirect equity holder of the Company, except as may be required under the Credit Agreement or by commercial law applicable to creditors generally, or as may be required under applicable securities laws.

(d) Compliance with Rule 144. The Company shall timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date of issuance set forth above pursuant to the Exchange Act. As long as the Holder owns any Conversion Securities, if the Company is not required to file reports pursuant to such securities laws, it will prepare and furnish to the Holder and make publicly available in accordance with Rule 144 such information as is required for the Holder to sell Conversion Securities under Rule 144. For so long as the Conversion Shares are not registered under an effective registration statement, the Company further covenants that it will take such further action as the Holder may reasonably request and cooperate in all respects with the Holder, including using its best efforts to provide instructions to the Transfer Agent in order to facilitate a sale or transfer of Conversion Shares, cause its legal counsel to issue a legal opinion to the Transfer Agent for such Conversion Shares if required by the Transfer Agent to effect the removal of the legend hereunder or procure the removal of any restrictive legend applicable to the Conversion Shares, all to the extent required from time to time to enable the Holder to sell such Conversion Shares without registration under the Securities Act in accordance with the requirements of the applicable exemptions provided by Rule 144, if available.

(e) Certain Amendments. The Company shall not adopt any amendment or modification of the Organization Documents of the Company that would adversely affect the Holder (in its capacity solely as a holder of this Instrument) without prior written consent of the Holder.

(g) Regulatory Requirements and Restrictions. In the event of any reasonable determination by the Holder that, by reason of any existing or future national, federal or state law, statute, rule, regulation, guideline, order, court or administrative ruling, request or directive (whether or not having the force of law and whether or not failure to comply therewith would be unlawful) including bank holding company related laws (collectively, a “Regulatory Requirement”), the Holder is effectively restricted or prohibited from holding this Instrument or the Conversion Shares (including any shares of capital stock or other securities distributable to the Holder in any merger, reorganization, readjustment or other reclassification), or otherwise realizing upon or receiving the benefits intended under this Instrument, the Company shall, and shall use its reasonable best efforts to take such action as the Holder and the Company shall jointly agree in good faith to be necessary to permit the Holder to comply with such Regulatory Requirement; provided, that, no action shall be required to be taken by the Company that would (i) require the Company or any of its Subsidiaries to change its line of business or effect any transactions involving the Company or any of its Subsidiaries (including, but not limited to, any corporate reorganization); (ii) materially interfere or would reasonably be expected to materially interfere with any financing, acquisition, corporate reorganization, merger, tender offer or other significant transaction involving the Company; (iii) require the Company to obtain shareholder approval; (iv) require the Company or any of its Subsidiaries to re-incorporate under the laws of any other jurisdiction or to register pursuant to the rules or regulations of any regulatory agency; or (v) result in any adverse tax consequences to the Company or any of its Subsidiaries.

SECTION 10. Registration Rights.

(a) As soon as reasonably possible, but in any event, no later than twelve (12) calendar months following the Commencement Date (and subject to satisfaction of the Registration Conditions), the Company shall prepare and file a shelf registration statement with the Commission to permit the public resale of the Registrable Securities (the “Registration Statement”). The Registration Statement required to be filed with the Commission pursuant to this Section 10(a) shall be on Form F-3 or Form F-10, or, if neither Form F-3 nor Form F-10 is then available to the Company, on Form F-1, Form S-3, Form S-1 or such other form of registration statement as is then available to effect a registration for resale of the Registrable Securities, covering the Registrable Securities, and shall contain a prospectus in such form as to permit any the Holder to sell the Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect, or in the case of Form F-10, any similar provision under Canadian securities laws) at any time beginning on the effective date for such Registration Statement. The Company shall use its best efforts to cause a Registration Statement filed pursuant to this Section 10(a) to be declared effective by the Commission as soon as possible, but in any event, within one hundred twenty (120) calendar days after the filing of the Registration Statement. A Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holder, including by way of an underwritten offering, if so elected by the Holder, subject to a minimum offering size of $3,000,000. During the Effectiveness Period, the Company shall use its best efforts to cause a Registration Statement filed pursuant to this Section 10(a) to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another registration statement is available for the resale of the Registrable Securities until the Registration Termination Time. The Company shall prepare and file a listing application with the Principal Market for the Company’s Common Shares (including Nasdaq and TSX, if applicable, or such other national securities exchange on which the Company’s Common Shares are then listed and traded, in each case, to the extent required by the rules and regulations of such exchange) to list all Conversion Shares issuable upon exercise of the conversion rights under this Instrument covered by a Registration Statement and shall have such Conversion Shares issuable upon exercise of the conversion rights under this Instrument promptly approved for listing on such Principal Market (including Nasdaq and TSX, if applicable, or such other national securities

10

exchange on which the Common Shares are then listed and traded, in each case, to the extent required by the rules and regulations of such exchange) by the effective date of such Registration Statement, subject only to official notice of issuance. Within two (2) Business Days of the effective date of a Registration Statement, the Company shall notify the Holder of the effectiveness of such Registration Statement.

(b) When effective, a Registration Statement (including the documents incorporated therein by reference) shall comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made).

(c) Without limiting Section 10(a), the Company agrees that it shall notify the Holder in writing at least five (5) Business Days prior to the filing of any registration statement under the Securities Act for purposes of a proposed public offering of Common Shares (including, without limitation, registration statements relating to secondary offerings of securities of the Company, but excluding (i) any registration statement relating to any employee benefit plan; (ii) with respect to any corporate reorganization or transaction under Rule 145 promulgated under the Securities Act, any registration statement related solely to the issuance or resale of securities issued in such a transaction; (iii) any registration statement related solely to Common Shares issued upon conversion of convertible debt securities; (iv) any registration statement filed under Rule 462(b) promulgated under the Securities Act; or (v) any registration statement on Form S-4, Form F-4 or Form S-8 not contemplated by clauses (i) through (iv) hereof) that would be filed at any time during which this Instrument is still outstanding and the Holder (together with the Holder’s Affiliates who are holders of the other conversion instruments forming the same series with this Instrument) continues to hold or beneficially own Registrable Securities that comprise at least one percent (1%) of the Common Shares then outstanding, and the Company will afford the Holder an opportunity to include in such registration statement all or part of the Registrable Securities, subject to the provisions hereof (such registration statement, the “Piggyback Registration Statement”). If the Holder desires to include in any such Piggyback Registration Statement all or any part of the Registrable Securities held by it, the Holder shall, within three (3) Business Days after the above-described notice from the Company, so notify the Company in writing and shall thereafter furnish the Company with such information as the Company reasonably requires to include such Registrable Securities in such offering; provided that, if such Registrable Securities represent Conversion Shares that have not yet been issued upon exercise of this Instrument, then the Holder shall also include a Notice of Conversion in respect of such Registrable Securities, it being understood that in no event shall the Company be obligated to include in any such Piggyback Registration Statement any Conversion Shares that have not been, or will not be, actually issued prior to the closing of the applicable offering due solely to the Holder’s failure to timely deliver such Notice of Conversion to the Company. The Company will use its commercially reasonable efforts to cause such Registrable Securities as to which inclusion shall have been so requested to be included in the Piggyback Registration Statement, subject to the second proviso in the next sentence. The Holder shall be entitled to sell the Registrable Securities included in a Piggyback Registration Statement in accordance with the method of distribution contemplated in the Piggyback Registration Statement; provided that, if the Piggyback Registration Statement relates to an underwritten offering, then (A) the Company shall be entitled to select the underwriters in its sole discretion and (B) the Holder must sell all Registrable Securities included on the Piggyback Registration Statement in such underwritten offering pursuant to an underwriting agreement containing terms and conditions that are customary for secondary offerings; and provided, further, that if the number of Registrable Securities requested by the Holder, together with the number of Common Shares that other persons that have duly requested to be included in such Piggyback Registration Statement pursuant to “piggyback rights” evidenced by another agreement (including, without limitation, the Existing Registration Rights Agreement) (collectively, “Requested Shares”), exceeds the maximum number of securities that may be sold in the applicable offering under such Piggyback Registration Statement without adversely affecting the success of such offering, as advised by the managing underwriters for such offering, then the number of Requested Shares to be included in such Piggyback Registration Statement will be allocated first, to such other persons party to the Existing Registration Rights Agreement; second, to the Holder; and third, to any other such persons. The Company may withdraw a Piggyback Registration Statement prior to its being declared effective without incurring any liability to the Holder and shall not be required to keep a Piggyback Registration Statement effective for longer than the period contemplated by the intended manner of distribution for the securities of the Company to be sold by the Company as described in the prospectus included in the Piggyback Registration Statement.

11

(d) For the avoidance of doubt, the rights to cause the Company to register Registrable Securities granted to the Holder by the Company under this Section 10 shall be fully assignable and transferrable to the same extent as this Instrument and the Conversion Shares are assignable and transferrable pursuant to Section 7 hereof, and any assignee or transferee of any Conversion Securities shall have all of the rights of the Holder to cause the Company to register Registrable Securities as set forth in this Section 10.

(e) The Holder (or any assignee or transferee) shall cooperate with the Company by, with reasonable promptness, supplying information and executing documents relating to such Holder (or transferee or assignee) or the securities of the Company owned by such Holder (or transferee or assignee) in connection with such registration under this Section 10 which are customary for offerings of this type or are required by applicable laws or regulations, including, but not limited to, furnishing to the Company a completed questionnaire in the form attached to this Instrument as Exhibit C. In the event the Holder does not comply with the immediately preceding sentence within a reasonable time prior to the initial filing in connection with such registration, the Company shall be permitted to exclude the Holder as a selling securityholder in connection therewith. In addition, the right of the Holder to include any of its Registrable Securities in any underwritten offering pursuant to a Piggyback Registration Statement will be subject to the execution and delivery by such Holder or its duly authorized representative or attorney-in-fact, of any related underwriting agreement and such other agreements or instruments (including customary “lock-up” agreements, custody agreements and powers of attorney), if any, as may be reasonably requested (to the same extent any such request is also made to the Company’s directors or officers and/or other selling shareholders in such offering) by the managing underwriters for such offering.

(f) Notwithstanding the foregoing provisions of this Section 10, the Company may, at any time, (i) delay the filing or delay or suspend the effectiveness of a Registration Statement, Piggyback Registration Statement or any pending or potential offering thereunder; (ii) without suspending such effectiveness, instruct the Holder not to sell any securities included in a Registration Statement or Piggyback Registration Statement; or (iii) delay the filing of any amendment or supplement to any Registration Statement or Piggyback Registration Statement, if, in the case of any of clause (i), (ii) or (iii), the Board has determined and promptly delivers a notice (a “Suspension Notice”) to the Holder in writing that in its reasonable good faith judgment (A) a material event has occurred or is likely to occur with respect to the Company that has not been publicly disclosed and, if disclosed, could reasonably be expected to materially and adversely affect the Company and its ability to consummate the registration of the resale of the Registrable Securities or (B) such registration could reasonably be expected to materially interfere with any material financing, acquisition, corporate reorganization, merger, tender offer or other significant transaction involving the Company (a “Suspension Period”), by providing the Holder with written notice of such Suspension Period and the reasons therefor. The Company will use its reasonable best efforts to provide such Suspension Notice at least ten (10) Business Days prior to the commencement of such a Suspension Period; provided, however, that in any event the Company will provide such notice no later than the commencement of such Suspension Period; provided, further, that in no event will a Suspension Period exceed thirty (30) days and in no event shall the total number of days subject to a Suspension Period during any consecutive twelve (12) month period exceed forty-five (45) days. Any Suspension Period will not be deemed to have ended until the Holder has received a notice from the Company stating that such Suspension Period has ended. The Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a Suspension Notice from the Company, such Holder will forthwith discontinue any offers and sales of such Registrable Securities under a Registration Statement or a Piggyback Registration Statement until such Holder’s receipt of the copies of the applicable supplemented prospectus and/or amended registration statement or until it is advised in writing by the Company that the use of the prospectus under the applicable Registration Statement or Piggyback Registration Statement, as applicable, may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such prospectus or amended registration statement. The Company and the Holder acknowledge and agree that in no way shall this Section 10(f) limit the Holder’s ability to sell securities without using a Registration Statement or a Piggyback Registration Statement.

12

(g) The Company shall pay all reasonable Registration Expenses.

5.

and deliver such new conversion instrument to the following address:

EXHIBIT B

PROCEDURES FOR ISSUANCE OF CONVERSION SHARES UPON EXERCISE

The procedures, rights and obligations set forth in this Exhibit B shall apply to the issuance and settlement of Conversion Shares pursuant to any Notice of Conversion delivered by the Holder or any Automatic Exercise, as applicable, pursuant to the attached Instrument, unless the Cash Settlement Amount is paid or proposed to be paid in accordance with Section 2(d) of the attached Instrument. Capitalized terms used but not otherwise defined herein have the meanings ascribed thereto in the attached Instrument.

(a) (x) Unless otherwise designated by the Holder in the applicable Notice of Conversion, on or before the fifth (5^th) Trading Day following the date on which the Company has received such Notice of Conversion; provided, that, such date shall be extended by up to five (5) Trading Days in the event the Company is required to adjust the Conversion Price in accordance with Section 5 of the attached Instrument, or (y) following any Automatic Exercise, on the Expiration Date (as applicable, the “Share Delivery Date”), the Company shall:

(i) if (A) there is an effective registration statement filed pursuant to the Securities Act covering the resale of such Conversion Shares by the Holder and (B) it is not otherwise deemed necessary under applicable securities laws for a restrictive legend to be affixed on such Conversion Shares upon issuance to the Holder, and, in each case, the Transfer Agent is participating in The Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program (“FAST”), upon the request of the Holder, credit such aggregate number of Conversion Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system; or

(ii) if (A) there is no effective registration statement filed pursuant to the Securities Act covering the resale of such Conversion Shares by the Holder, (B) it is deemed necessary under applicable securities laws for a restrictive legend to be affixed on such Conversion Shares upon issuance to the Holder, and/or (C) if the Transfer Agent is not then participating in the DTC’s FAST, upon the request of the Holder, issue and deliver (via reputable overnight courier) to the address as specified in the Notice of Conversion (or, in the case of an Automatic Exercise, to any address specified by the Holder in writing), a Direct Registration System statement, registered in the name of the Holder or its designee, for the number of Conversion Shares to which the Holder shall be entitled pursuant to such exercise, and if applicable, including a restrictive legend thereon.

If any restrictive legend is placed on Conversion Shares, the Company agrees that, as promptly as practicable following the Legend Removal Date (as defined below) in respect of such Conversion Shares, it will, subject to receipt of such representations and covenants of the Holder and the Holder’s executing broker, if any, as the Company or the Transfer Agent may reasonably require in connection therewith, deliver or cause to be delivered to the Holder a book entry position representing such Conversion Shares that is free from any restrictive legend (and the Company shall cause to be issued any legal opinion required by the Transfer Agent with respect thereto). The Company shall not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this section, except as may be required under applicable securities laws. To the extent that book entry positions are issued representing the Conversion Shares, such book entry positions subject to legend removal hereunder shall be delivered by the Transfer Agent to the Holder by issuing to the Holder by electronic delivery at the applicable balance account at DTC, the Transfer Agent or any custodian of the Holder, as applicable, at the Holder’s election. Any fees (with respect to the Transfer Agent, the Company’s counsel or otherwise) associated with the issuance of such opinion or the removal of such legend shall be borne by the Company. “Legend Removal Date”, in respect of any Conversion Shares, means the earliest of the date that (A) the

Company has received appropriate notice from the Holder that such Conversion Shares have been or are being sold or transferred pursuant to an effective registration statement under the Securities Act, (B) the Company has received appropriate notice from the Holder that such Conversion Shares have been or are being sold or transferred pursuant to Rule 144 (if the transferor is not an affiliate of the Company); or (C) the Company has received appropriate notice from the Holder that such Conversion Shares are eligible for resale under Rule 144 without volume or manner-of-sale restrictions.

(b) Upon delivery of a Notice of Conversion or any Automatic Exercise, as applicable, the Holder shall be deemed to have become the registered legal and beneficial owner of the Conversion Shares with respect to which the conversion rights under this Instrument have been exercised, irrespective of the date such Conversion Shares are credited to the Holder’s DTC account or the date of delivery of the certificate(s) evidencing such Conversion Shares (as the case may be). If the attached Instrument is submitted in connection with any exercise of the conversion rights pursuant to Section 2(e) of the attached Instrument and the Maximum Conversion Amount then available for conversion into Conversion Shares is greater than the Aggregate Conversion Amount being converted into Conversion Shares upon such exercise, then, at the request of the Holder, the Company shall as soon as practicable and in no event later than two (2) Business Days after the date of settlement pursuant to Section 2(e) of the attached Instrument and, at its own expense, issue and deliver to the Holder (or its designee) a new conversion instrument representing the right to convert the newly calculated maximum amount, after giving effect to such exercise, of the Outstanding Amount of Loans owing to the Holder for subscription for Conversion Shares (such newly calculated maximum amount being an amount equal to (i) the Maximum Conversion Amount which was available for conversion immediately prior to such exercise, minus (ii) the Aggregate Conversion Amount for such exercise).

(c) The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation, fees and expenses of the Transfer Agent) that may be payable with respect to the issuance of Conversion Shares upon exercise of the conversion rights under the attached Instrument (but not any subsequent transfer of Conversion Shares so issued).

(d) Notwithstanding any other provision in this Agreement, the Holder may elect, at its sole discretion, to receive unregistered Conversion Shares issued in response to a Notice of Conversion or any Automatic Exercise instead of Conversion Shares registered pursuant to any registration statement filed with the Commission to register the Conversion Shares. In such case, the Holder agrees and acknowledges that any such unregistered Conversion Shares shall bear a securities law legend substantially similar to the legend on the facing page of the attached Instrument, to the extent required by applicable securities laws.
