27.3 Dividends.

(a) Dividends. No dividends shall accrue or be payable to holders of the Series A Preferred Shares except as set forth in Articles 27.3(b) and (c).

(b) Participating Cash Dividends. If the Company declares, makes or pays any cash dividend or distribution in respect of all or substantially all holders of Common Shares (a “Common Dividend”), each shareholder holding Series A Preferred Shares shall receive a dividend (a “Participating Cash Dividend”) in the same amount in respect of each Preferred Share held thereby, at the same time as holders of Common Shares, as such holders of Series A Preferred Shares would have received if, immediately prior to the record date of such Common Dividend, they had held the number of Common Shares issuable upon the Mandatory Conversion Date. If and to the extent that the Company does not for any reason pay the entire Participating Cash Dividend when the Common Dividend is paid to the holders of Common Shares, during the period in which such Participating Cash Dividend remains unpaid, an additional dividend (the “Participating Cash Penalty Dividends”) shall be payable at an annual rate equal to 8.75% compounded annually on the amount of the unpaid Participating Cash Dividend through the daily addition of such Participating Cash Penalty Dividends to the Purchase Price (whether or not such Participating Cash Penalty Dividends are declared by the board).

If the Company distributes shares, evidences of its indebtedness or other assets, securities or property, including rights to acquire assets, securities or property, to all or substantially all holders of Common Shares (an “In-Kind Common Dividend”), including without limitation any spin-off of one or more subsidiaries or businesses of the Company but excluding: (I) dividends or distributions referred to in Article 27.6(f)(i); and (II) cash dividends with respect to which holders of Series A Preferred Shares are entitled to Participating Cash Dividends, then such shareholders shall receive in such distribution or other transaction, at the same time and in the same manner as holders of Common Shares, the same type and amount of consideration (the “Participating In-Kind Dividend” and, together with the Participating Cash Dividend, the “Participating Dividends”) as holders of Series A Preferred Shares would have received if, immediately prior to the record date of such In-Kind Common Dividend, they had held the number of Common Shares issuable upon the Mandatory Conversion Date. To the extent that the Company establishes or adopts a shareholder rights plan or agreement (i.e., a “poison pill”) (each, a “Shareholder Rights Plan”), the Company shall ensure that such shareholders will receive, as a Participating In-Kind Dividend, rights under the Shareholder Rights Plan with respect to any Common Shares that at the time of such distribution would be issuable upon conversion of the Preferred Shares. If and to the extent that the Company does not for any reason pay the entire Participating In-Kind Dividend when the In-Kind Common Dividend is paid to the holders of Common Shares, during the period in which such Participating In-Kind Dividend remains unpaid, an additional dividend (the “Participating In-Kind Penalty Dividends” and, together with Participating Cash Penalty Dividends, the “Participating Penalty Dividends”) shall be payable at an annual rate equal to 8.75% on the amount of the unpaid Participating In-Kind Dividend through the daily addition of such Participating In-Kind Penalty Dividends to the Purchase Price (whether or not such Participating In-Kind Penalty Dividends are declared by the board).

27.4 Liquidation Preference.

(a) Upon any Liquidation Event, each Series A Preferred Share entitles the holders thereof to receive and to be paid out of the assets of the Company legally available for distribution to the Company’s shareholders, before any distribution or payment may be made to a holder of any Junior Securities, an amount in cash per share equal to an amount the holders of such share would have received upon such Liquidation Event had such shareholder converted

such Series A Preferred Share into Common Shares (or Reference Property, to the extent applicable) upon the Mandatory Conversion Date.

(b) If upon any such Liquidation Event, the assets of the Company legally available for distribution to all shareholders of the Company are insufficient to pay the holders of Series A Preferred Shares the full Liquidation Preference and the holders of all Parity Securities the full liquidation preferences to which they are entitled, the shareholders of the Series A Preferred Shares and the holders of such Parity Securities will share ratably in any such distribution of the assets of the Company in proportion to the full respective amounts to which they are entitled.

(c) After payment to the holders of the Series A Preferred Shares of the full Liquidation Preference to which they are entitled, such shareholders, as such, will have no right or claim to any of the assets of the Company.

(d) The value of any property not consisting of cash that is distributed by the Company to the holders of the Series A Preferred Shares will equal the fair market value thereof (as determined in good faith by the board) on the date of distribution.

(e) No holder of Junior Securities shall receive any cash upon a Liquidation Event unless the entire Liquidation Preference in respect of the Series A Preferred Shares has been paid in cash. To the extent that there is insufficient cash available to pay the entire Liquidation Preference in respect of the Series A Preferred Shares and any liquidation preference in respect of Parity Securities in full in cash upon a Liquidation Event, the holders of the Series A Preferred Shares and the holders of such Parity Securities will share ratably in any cash available for distribution in proportion to the full respective amounts to which they are entitled upon such Liquidation Event.

(f) For the avoidance of doubt, a Transaction or Fundamental Change shall not be treated as a Liquidation Event for the purpose of this Article 27.4 (unless in connection therewith, the liquidation, dissolution or winding up of the Company is specifically approved), but shall be treated as provided for in Article 27.6(c) hereof.

27.5. Voting Rights. The Series A Preferred Shares shall not have the right to vote on any matters except as required by law, including under the British Columbia Business Corporations Act. Where such vote is required by law, as of any record date or other determination date, each shareholder holding Series A Preferred Shares shall be entitled to the number of votes such shareholder would have had if all Series A Preferred Shares held by such shareholder on such date would be converted into Common Shares on the Mandatory Conversion Date.

27.6. Conversion. Each Series A Preferred Share is convertible into Common Shares (or Reference Property, to the extent applicable) as provided in this Article 27.6.

(a) Conversion at the Option of Holders of Series A Preferred Shares. Subject to Article 27.6(b) hereof, each holder of Series A Preferred Shares is entitled to convert any or all outstanding Series A Preferred Shares held by such shareholder and receive therefor the property described in Article 27.6(c) upon such conversion in the event of (A) a transaction that involves a fundamental transfer of value to the Common Shares by means of a distribution, event or other transaction in which the Preferred Shares do not have the right to pursuant to Articles 27.3(b) or (c), or (B) a Fundamental Change. In order to convert Series A Preferred Shares into Common Shares (or Reference Property, to the extent applicable), the holder of the Series A Preferred Shares must surrender the certificates representing such Series A Preferred Shares at the office of the Company’s transfer agent for the Series A Preferred Shares (or at the registered and records

office of the Company, if the Company serves as its own transfer agent), together with (x) written notice that such shareholder elects to convert all or part of the Series A Preferred Shares represented by such certificates as specified therein, (y) a written instrument or instructions of transfer or other documents and endorsements reasonably acceptable to the transfer agent or the Company, as applicable (if reasonably required by the transfer agent or the Company, as applicable), and (z) funds for any stock transfer, documentary, stamp or similar taxes, if payable by the shareholder pursuant to Article 27.6(e)(i). Except as provided in Article 27.6(b), the date the transfer agent or the Company, as applicable, receives such certificates, together with such notice and any other documents and amounts required to be paid by the holders of Series A Preferred Shares pursuant to this Article 27.6(a), will be the date of conversion (the “Optional Conversion Date”).

(b) Mandatory Conversion. In the event that any holder of Series A Preferred Shares has not elected to convert the Series A Preferred Shares held by such holder pursuant to Article 27.6(a) on or before the Mandatory Conversion Date, then such shareholder’s Series A Preferred Shares shall be automatically converted (without any further action by the shareholder and whether or not the certificates representing the Series A Preferred Shares are surrendered), in whole and not in part, into the property described in Article 27.6(c), effective as of the Mandatory Conversion Date. As promptly as practicable (but in no event more than five (5) business days) following the Mandatory Conversion Date, the Company shall deliver a notice to any shareholder whose Series A Preferred Shares have been converted pursuant to this Article 27.6(b), informing such shareholder of the number of Common Shares into which such Series A Preferred Shares have been converted, together with certificates evidencing such Common Shares. Notwithstanding the foregoing, any notice delivered by the Company in compliance with this Article 27.6(b) shall be conclusively presumed to have been duly given, whether or not such holder of Series A Preferred Shares actually receives such notice, and neither the failure of a shareholder to actually receive such notice given as aforesaid nor any immaterial defect in such notice shall affect the validity of the proceedings for the conversion of the Series A Preferred Shares as set forth in this Article 27.6(b).

(c) Amounts Received Upon Conversion. Upon a conversion of Series A Preferred Shares pursuant to Articles 27.6(a) or 27.6 (b), the holder of such converted Series A Preferred Shares shall, subject to the limitations and adjustments pursuant to the first paragraph of Article 27.6, receive in respect of each Series A Preferred Share:

(i) a number of Common Shares (or Reference Property, to the extent applicable) equal to the amount determined by dividing (A) the Purchase Price for the Series A Preferred Share to be converted plus an amount equal to 8.75% of the Purchase Price per annum compounded annually including, in the case of a conversion pursuant to Article 27.6(a), as if the Mandatory Conversion Date had occurred irrespective of the timing of such conversion (the “Liquidation Preference”) by (B) the Conversion Price in effect at the time of conversion;

(ii) cash in an amount equal to the amount of any accrued but unpaid Participating Cash Dividends (to the extent not included in the Purchase Price) on the Series A Preferred Shares being converted; provided that, to the extent the Company is prohibited by law or by contract from paying such amount, then the Company shall provide written notice to the applicable holder of such inability to pay, and at the written election of the shareholder (which written election shall be delivered to the Company within five (5) business days of receipt of such written notice from the Company), the Company shall either pay such amount as soon as payment is no longer so prohibited or issue Common Shares (or Reference Property, to the extent applicable) in the manner specified in Article 27.6(c)(i) as if the amount of such accrued but unpaid Participating Cash Dividends were added to the Purchase Price; and

(iii) any accrued and unpaid Participating In-Kind Dividends.

(d) Fractional Shares. No fractional shares of Common Shares (or fractional shares in respect of Reference Property, to the extent applicable) will be issued upon conversion of the Series A Preferred Shares. In lieu of fractional shares, the Company shall pay cash in respect of each fractional share equal to such fractional amount multiplied by the Daily VWAP of the Common Shares over the thirty (30) consecutive Trading Day period ending on the Trading Day immediately preceding the Optional Conversion Date or the Mandatory Conversion Date, as the case may be (each, a “Conversion Date”). If more than one Series A Preferred Share is being converted at one time by the same holder thereof, then the number of full shares issuable upon conversion will be calculated on the basis of the aggregate number of Series A Preferred Shares converted by such shareholder at such time.

(e) Mechanics of Conversion.

(i) As soon as reasonably practicable after the Conversion Date (and in any event within four (4) Trading Days after either such date), the Company shall issue and deliver to such shareholder one or more certificates for the number of Common Shares (or Reference Property, to the extent applicable) to which such holder of Series A Preferred Shares is entitled, together with, at the option of the shareholder, a certified cheque or wire transfer of immediately available funds for payment of fractional shares and any payment required by Article 27.6(c)(ii) in exchange for the certificates representing the converted Series A Preferred Shares. Such conversion will be deemed to have been made on the Conversion Date, and the Person entitled to receive the Common Shares (or Reference Property, to the extent applicable) issuable upon such conversion shall be treated for all purposes as the record holder of such Common Shares (or Reference Property, to the extent applicable) on such date. The delivery of Common Shares upon conversion of Series A Preferred Shares shall be made, at the option of the applicable shareholder, in certificated form or by book-entry. Any such certificate or certificates shall be delivered by the Company to the appropriate shareholder on a book-entry basis or by mailing certificates evidencing the shares to the holders of the Series A Preferred Shares at their respective addresses as set forth in the conversion notice. In cases where fewer than all the Series A Preferred Shares represented by any such certificate are to be converted, a new certificate shall be issued representing the unconverted Series A Preferred Shares. The Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of Common Shares (or Reference Property, to the extent applicable) upon conversion or due upon the issuance of a new certificate for any Series A Preferred Shares not converted to the converting shareholder; provided that the Company shall not be required to pay any such amounts, and any such amounts shall be paid by the converting shareholder, in the event that such Common Shares or Series A Preferred Shares are issued in a name other than the name of the converting shareholder.

(ii) For the purpose of effecting the conversion of Series A Preferred Shares, the Company shall: (A) at all times reserve and keep available, free from any preemptive rights, out of its treasury or authorized but unissued Common Shares (or Reference Property, to the extent applicable) the full number of Common Shares (or Reference Property, to the extent applicable) deliverable upon the conversion of all outstanding Series A Preferred Shares after taking into account any adjustments to the Conversion Price from time to time pursuant to the terms of this Article 27.6 and any increases to the Purchase Price from time to time and assuming for the purposes of this calculation that all outstanding Series A Preferred Shares are held by one holder) and (B) without prejudice to any other remedy at law or in equity any holder of Series A Preferred Shares may have as a result of such default, take all actions reasonably required to amend its Notice of Articles or Articles, as expeditiously as reasonably practicable, to increase the authorized and available amount of Common Shares (or Reference Property, to the extent applicable) if at any time such amendment is necessary in order for the Company to be able to satisfy its obligations under this Article 27.6.

(iii) From and after the Conversion Date, the Series A Preferred Shares converted on such date, will no longer be deemed to be outstanding and all rights of the holder thereof including the right to receive Dividends, but excluding the right to receive from the Company the Common Shares (or Reference Property, to the extent applicable) or any cash payment upon conversion, and except for any rights of shareholders holding Series A Preferred Shares (including any voting rights) pursuant to this Article 27.6 which by their express terms continue following conversion or, for the avoidance of doubt, rights which by their express terms continue following conversion pursuant to the Subscription Agreement, shall immediately and automatically cease and terminate with respect to such Series A Preferred Shares; provided that, in the event that a Series A Preferred Share is not converted due to a default by the Company or because the Company is otherwise unable to issue the requisite Common Shares (or Reference Property, to the extent applicable), such Series A Preferred Share will, without prejudice to any other remedy at law or in equity any shareholder holding Series A Preferred Shares may have as a result of such default, remain outstanding and will continue be entitled to all of the rights attendant to such Series A Preferred Share as provided herein.

(v) The Company shall comply with all federal, provincial and state laws, rules and regulations and applicable rules and regulations of the Exchange on which Common Shares (or Reference Property, to the extent applicable) are then listed. If any Common Shares (or Reference Property, to the extent applicable) to be reserved for the purpose of conversion of Series A Preferred Shares require registration with or approval of any Person or group (as such term is defined in Section 13(d)(3) of the Exchange Act) under any federal or state law or the rules and regulations of the Exchange on which Common Shares (or Reference Property, to the extent applicable) are then listed before such shares may be validly issued or delivered upon conversion, then the Company will, as expeditiously as reasonably practicable, use commercially reasonable efforts to secure such registration or approval, as the case may be. So long as any Common Shares (or Reference Property, to the extent applicable) into which the Series A Preferred Shares are then convertible is then listed on an Exchange, the Company will list and keep listed on any such Exchange, upon official notice of issuance, all Common Shares (or Reference Property, to the extent applicable) issuable upon conversion.

(vi) All Common Shares (or Reference Property, to the extent applicable) issued upon conversion of the Series A Preferred Shares will, upon issuance by the Company, be duly and validly issued, fully paid and nonassessable, not issued in violation of any preemptive or similar rights arising under law or contract and free from all taxes, liens and charges with respect to the issuance thereof, and the Company shall take no action which will cause a contrary result.

(f) Adjustments to Conversion Price.

(i) Common Stock Dividends, Splits and Combinations. The Conversion Price shall be adjusted if the Company issues Common Shares as a dividend or distribution on its Common Shares, or if the Company effects a share split or share combination with respect to Common Shares, the Conversion Price based on the following formula:

where,

CP0 = the Conversion Price in effect immediately prior to the open of business on the Ex-Date for such dividend or distribution, or the open of business on the effective date of such share split or share combination, as the case may be;

CP1 = the Conversion Price in effect immediately after the open of business on the Ex-Date for such dividend or distribution, or the open of business on the effective date of such share split or share combination, as the case may be;

OS0 = the number of Common Shares outstanding immediately prior to the open of business on the Ex-Date for such dividend or distribution, or the open of business on the effective date of such share split or share combination, as the case may be; and

OS1 = the number of Common Shares outstanding immediately after such dividend or distribution, or such share split or share combination, as the case may be.

Any adjustment made under this Article 27.6(f)(i) shall become effective immediately after the open of business on the Ex-Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this Article 27.6(f)(i) is declared but not so paid or made, or any share split or combination of the type described in this Article 27.6(f)(i) is announced but the outstanding Common Shares are not split or combined, as the case may be, the Conversion Price shall be immediately readjusted, effective as of the date the board determines not to pay such dividend or distribution, or not to split or combine the outstanding Common Shares, as the case may be, to the Conversion Price that would then be in effect if such dividend, distribution, share split or share combination had not been declared or announced.

(ii) Impact of Conversion. Notwithstanding anything in this Article 27.6(f) to the contrary, if a Conversion Price adjustment becomes effective pursuant to Article 27.6(f)(i) on any Ex-Date as described above, and a shareholder holding Series A Preferred Shares that converts its Series A Preferred Shares on or after such Ex-Date and on or prior to the related record date would be treated as the record holder of Common Shares as of the related Conversion Date based on an adjusted Conversion Price for such Ex-Date and participate on an adjusted basis in the related dividend or other event giving rise to such adjustment, then, notwithstanding the foregoing Conversion Price adjustment provisions, the Conversion Price adjustment relating to such Ex-Date will not be made for such converting shareholder. Instead, such shareholder will be treated as if such shareholder were the record owner of the Common Shares on an un-adjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(iii) Reference Property. In the case of any recapitalization, reclassification or change of the Common Shares (other than changes resulting from a subdivision or combination described in Article 27.6(f)(i)), a consolidation, merger or combination involving the Company, a sale, lease or other transfer to a third party of all or substantially all of the assets of the Company (or the Company and its subsidiaries on a consolidated basis), or any statutory share exchange, in each case as a result of which the Common Shares would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any of the foregoing, a “Transaction”), then, at the effective time of the Transaction, the right to convert each Series A Preferred Share will be changed into a right to convert such Series A Preferred Share into the kind and amount of shares of stock, other securities, other property or assets (including cash or any combination thereof) (the “Reference Property”) that a holder of Series A Preferred Shares would have received in respect of the Common Shares issuable upon conversion of such Series A Preferred Shares immediately prior to such Transaction. In the event that holders of Common Shares have the opportunity to elect the form of consideration to be received in the Transaction, the Company shall make adequate provision whereby

the holders of Series A Preferred Shares shall have a reasonable opportunity to determine the form of consideration into which Series A Preferred Shares shall be convertible from and after the effective date of the Transaction. Any such determination by the holders of Series A Preferred Shares shall be subject to any limitations to which all holders of Common Shares are subject, such as pro rata reductions applicable to any portion of the consideration payable in the Transaction, and shall be conducted in such a manner as to be completed at approximately the same time as the time elections are made by holders of Common Shares. The provisions of this Article 27.6(f)(iii) and any equivalent thereof in any such securities similarly shall apply to successive Transactions. The Company shall not become a party to any Transaction unless its terms are in compliance with the foregoing.

(iv) Rules of Calculation; Treasury Shares. All calculations will be made to the nearest one-hundredth of a cent or to the nearest one-ten thousandth of a share. Except as explicitly provided herein, the number of Common Shares (or Reference Property, to the extent applicable) outstanding will be calculated on the basis of the number of issued and outstanding Common Shares (or Reference Property, to the extent applicable), not including shares held in the treasury of the Company. The Company shall not pay any dividend on or make any distribution to Common Shares (or Reference Property, to the extent applicable) held in treasury.

(v) Notice of Record Date. In the event of:

(A) any event described in Article 27.6(f)(i);

(B) any Transaction to which Article 27.6(f)(iii) applies; or

then the Company shall mail to the holders of the Series A Preferred Shares at their last addresses as shown on the records of the Company, at least twenty (20) days prior to the record date specified in (A) below or twenty (20) days prior to the date specified in (B) below, as applicable, a notice stating:

(A) the record date for the dividend, other distribution, stock split or combination or, if a record is not to be taken, the date as of which the holders of record of Common Shares to be entitled to such dividend, other distribution, stock split or combination; or

(B) the date on which such reclassification, change, dissolution, liquidation, winding-up or other event constituting a Transaction, is reasonably anticipated to become effective or otherwise occur, and the date as of which it is expected that holders of Common Shares of record will be entitled to exchange their Common Shares for Reference Property, other securities or other property deliverable upon such reclassification, change, liquidation, dissolution, winding-up or a Transaction is reasonably anticipated to occur.

(vi) Certificate of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Article 27.6, the Company at its expense shall as promptly as reasonably practicable compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Series A Preferred Shares a certificate, signed by an officer of the Company (in his or her capacity as such and not in an individual capacity), setting forth (A) the calculation of such adjustments and readjustments in reasonable detail, (B) the facts upon which such adjustment or readjustment is based, (C) the Conversion Price then in effect, and (D) the number of

Common Shares (or Reference Property, to the extent applicable) and the amount, if any, of the shares, other securities or other property (including but not limited to cash and evidences of indebtedness) which then would be received upon the conversion of a Series A Preferred Share.

(vii) No Impairment. The Company will not, except with any approval required by Article 27.5 hereof and applicable law, by amendment of the Articles of the Company or through any reorganization, recapitalization, transfer of assets, merger, consolidation, dissolution, issue or sale of shares or other securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Article 27.6 and in the taking of all such actions as may be necessary or appropriate in order to protect the conversion rights of the holders of the Series A Preferred Shares against impairment; provided, however, that nothing in this Article 27.6 shall serve to limit or otherwise affect the right of the Company to enter into a Transaction or effect a Fundamental Change.

(f) No Other Conversion Rights. The holders of Series A Preferred Shares shall have no rights of conversion other than as specifically set forth herein.

2.1.4 In the event that any Shareholder Designee resigns, dies, becomes incapacitated or otherwise ceases to be a director prior to the expiration of his or her term as a director, such vacancy shall be filled in accordance with the provisions of section 5 of Part 28 of the Articles. The Company shall use all commercially reasonable steps, promptly upon receipt by it of a written notice from the Shareholder identifying a Shareholder Designee to fill such vacancy and in any event no later than five (5) business days following receipt of such written notice, as are necessary to call

a meeting of the board of directors to vote on the appointment of such Shareholder Designee to fill such vacancy (or to obtain a vote of the directors by way of unanimous written resolution) and take all such other steps as are required by the Articles and the Act with respect to such appointment.

2.2 Voting

Unless and until the Shareholder no longer has the right to appoint a Shareholder Designee pursuant to the Articles and provided that the Company is in material compliance with the terms of this Agreement and the Articles, the Shareholder will vote, and will cause its Affiliates to vote, all of the shares of the Company then owned by the Shareholder and its Affiliates:

2.2.1 in favour of:

(a) the election of any person or persons nominated for election to the Board by the Board from time to time in accordance with the Articles, and

2.2.2 against:

(a) the election of any person nominated by anyone other than the Board.

4.2 Confidentiality

The Shareholder agrees that, unless the written consent of the Company is obtained, the Shareholder will not at any time use, disclose or make available, to any Person, any information (herein “Confidential Information”) concerning the business or affairs of the Company acquired pursuant to the provisions of Section 4.1 and

The Company shall provide, and shall cause each of its subsidiaries to provide, such information to the Shareholder as direct and indirect owners of the Shareholder may reasonably require to timely file and maintain a “qualified electing fund” election (as defined in Section 1295(a) of the Code) with respect to any such entity.

For greater certainty, the Company (x) shall not be required to retain a third party solicitation agent, and (y) shall include the name of the RS nominee(s) to stand for election to the board of directors of the Company in the proxy to be delivered to each holder of Company Shares in respect of the Shareholder Meeting.

For the purpose of this Agreement, the “Lock-Up Period” shall mean such period commencing on the date hereof and ending on the earlier of (i) the fourth anniversary of the date hereof, and (ii) the occurrence of any of the events set forth in the Amended and Restated Standstill Agreement that results in the restrictions set forth in Section 3 thereof not applying.

The Shareholder represents and warrants that it is not a party to any agreement or understanding that would cause a breach of this Agreement if it were entered into during the period in which the restrictions set forth herein are effective.

The Shareholder acknowledges that the execution, delivery and performance of this Agreement is a material inducement to the Company to enter into the Subscription Agreement, and the Company shall be entitled to specific performance of the Shareholder’s obligations hereunder.

The Shareholder further agrees to waive any requirement for the

securing or posting of any bond in connection with such remedy. All rights under this Agreement are cumulative, not exclusive, and will be in addition to all rights and remedies available to the Company at law or in equity.

The Shareholder and the Company agree that this Agreement shall automatically terminate and be of no further force or effect if (a) the Company is in material breach of its obligations under Articles 2 or 4 of the Governance Agreement or Part 27 or Part 28 of the Company’s Articles and (b) such breach remains uncured for at least thirty (30) days after notice to the Company thereof.

The Shareholder agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions. In furtherance of the foregoing, the Company and any duly appointed transfer agent for the registration or transfer of the securities described herein are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Agreement.

The Shareholder hereby represents and warrants that the Shareholder has full power and authority to execute, deliver and perform this Agreement. All authority herein conferred or agreed to be conferred and any obligations of the Shareholder shall be binding upon the successors, assigns, heirs or personal representatives of the Shareholder. This Agreement may not be amended or otherwise modified in any respect without the written consent of the Company and the Shareholder.

This Agreement shall become effective only upon the Tier 1 Closing Date.

THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE PROVINCE OF BRITISH COLUMBIA AND THE LAWS OF CANADA APPLICABLE THEREIN, WITHOUT REGARD TO THE CONFLICT OF LAWS PRINCIPLES THEREOF.

Any and all disputes arising under this Agreement, whether as to interpretation, performance or otherwise, shall be subject to the non-exclusive jurisdiction of the courts of the Province of British Columbia and each of the Parties hereby irrevocably attorns to the jurisdiction of the courts of such jurisdiction.

“Lock-up Agreement” means the amended and restated Lock-Up Agreement dated as of the date hereof between the Company and the Shareholder.

“Shareholder Maximum Ownership Percentage” means 49.99% of the outstanding Common Stock, including shares of Common Stock the Shareholder would be entitled to acquire, assuming all Preferred Shares held by the Shareholder on any applicable date were converted into Common Stock as of the Mandatory Conversion Date (as such term is defined in the rights and restrictions attached to the Preferred Shares).

2. Original Agreement. The Original Agreement is hereby amended and restated in its entirety by this Agreement.

3. Standstill. For a period commencing on the date hereof and ending on the earlier of (i) forty-eight (48) months following the Tier 1 Closing and (ii) the date upon which the Shareholder no longer has the right to nominate at least one (1) director to the Company’s board of directors (the “Board”) pursuant to the Governance Agreement and/or Part 28 of the Company’s Articles, the Shareholder shall not, without the prior written consent of the Company, directly or indirectly:

a. acquire, offer to acquire, or agree to acquire ownership (including, but not limited to, beneficial ownership as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (“Exchange Act”)), by purchase or otherwise, any additional shares of Common Stock, or any rights or options to acquire any such securities or any securities convertible into such securities; provided that, in the event that at any time, whether due to an increase in the total outstanding shares of Common Stock , a sale of shares of Common Stock or Preferred Shares by the Shareholder (made in compliance with the provisions of the Lock-Up Agreement) or otherwise, the Shareholder beneficially owns, directly or indirectly, Common Stock representing less than the Shareholder Maximum Ownership Percentage, the Shareholder may acquire additional shares of Common Stock or rights or options to acquire any such securities or any securities convertible into such securities; provided, further, that the Shareholder’s ownership percentage will not exceed the Shareholder Maximum Ownership Percentage;

b. call or seek to call any meeting of the stockholders of the Company;

e. form or join in a partnership, syndicate or other group, including, without limitations, a “group” as defined under Section 13(d) of the Exchange Act, with respect to the Common Shares, or deposit any Common Shares in a voting trust, arrangement or agreement, except for such actions that may be permitted under the Lock-Up Agreement;

Notwithstanding anything contained in this Agreement to the contrary, the Shareholder shall not be required to dispose of any of its holdings of Preferred Shares or Common Shares if (i) the number of shares of Common Stock is reduced or if the aggregate ownership of the Shareholder is increased solely as a result of a recapitalization or other transaction of the Company and as a

result of such transaction, the Shareholder’s ownership exceeds the Shareholder Maximum Ownership Percentage or (ii) a majority of the members of the Board of the Company (other than the Shareholder nominees) approve a transaction pursuant to which the Shareholder’s ownership exceeds the Shareholder Maximum Ownership Percentage.

The restrictions set forth in this Section 3 shall not apply if any of the following occurs:

a. in the event that the Company enters into a definitive agreement for a merger, consolidation or other business combination transaction as a result of which the stockholders of the Company would own (including, but not limited to, beneficial ownership) voting securities of the resulting corporation having 50% or less of the total voting power of the outstanding voting securities;

b. in the event that a bona fide tender offer or exchange offer for at least a majority of the outstanding voting securities of the Company is commenced by a third person (not involving any breach of this Section 3 by the Shareholder); or

c. the Company solicits from one or more persons or enters into discussions with one or more persons regarding, a proposal with respect to a merger of, or a business combination transaction involving, the Company, in each case without similarly soliciting a proposal from the Shareholder, or the Company makes a public announcement that it is seeking to sell itself and/or explore strategic alternatives which could lead to a sale, restructuring, business combination, merger or other similar transaction and, in such event, such announcement is made with the approval of the Board.

Nothing in this Section 3 shall restrict the Shareholder from (i) making any proposal directly to the Board on a confidential basis; or (ii) voting its Common Stock in any manner the Shareholder determines in its sole discretion; provided that, the Shareholder complies with any voting requirements applicable to the Shareholder set forth in the Governance Agreement and/or the Company’s Articles.

4. Termination. The Shareholder may terminate this Agreement if the Company is in material breach of Articles 2 or 4.2 of the Governance Agreement or Part 27 or Part 28 of the Company’s Articles and such breach remains uncured for at least fifteen (15) days after notice to the Company thereof.
