ARTICLE 2

MANAGEMENT OF CORPORATION

2.1 Agreement Respecting Voting/Credit Agreement Debt

For so long as this Agreement remains in effect, each Shareholder agrees to vote any and all Shares held by it from time to time so as to elect and maintain in office the Francisco Partners Nominees (as defined in Section 2.2) and the Xxxxxxxx Nominees (as defined in Section 2.2) as members of the Board of Directors, and to cause the Corporation to act in compliance with all of

- 5 -

the provisions of this Agreement and in particular to vote to approve any Transfer which is permitted and otherwise made in compliance with this Agreement; provided, however, that no Shareholder shall be subject to the voting agreements in this Section 2.1 or elsewhere in this Agreement if such Shareholder is PTIC or if such Shareholder, together with its Affiliates, holds less than 3% of the Common Shares (calculated on an as-if converted to Common Shares basis). It is acknowledged and agreed that no Shareholder shall be bound to vote in respect of any matter in the same manner as its nominee director voted in respect of such matter in his or her capacity as a director on the Board of Directors. The Shareholders agree that the Credit Agreement Debt constitutes “Designated Debt” as defined in the Articles of Amendment.

2.2 Francisco Partners Nominees and Xxxxxxxx Nominees on the Board of Directors

The Board of Directors will be composed of nine members unless a change to the number of directors is approved by Francisco Partners II (Cayman), L.P. as the Controlling Shareholder of Arsenal Holdco I, S.a.r.l. The number of directors to be nominated by Francisco Partners II (Cayman), L.P. (each, a “Francisco Partners Nominee”) shall be equal to the product of the number of directors the Board of Directors is composed of and the number of Common Shares owned by the holders of Class 1 Shares (calculated on an as-if converted to Common Shares basis) divided by the number of outstanding Common Shares (calculated on an as-if converted into Common Shares basis) and rounded up to the nearest whole number; provided, however, that Francisco Partners II (Cayman), L.P. shall be entitled to nominate at least one director so long as the Francisco Partners Group holds at least 5% of the Common Shares (calculated on as-if converted to Common Shares basis); and provided, further, however, that Francisco Partners II (Cayman), L.P. shall not be entitled to nominate more than four directors unless the Francisco Partners Group holds at least 55% of the Common Shares (calculated on as-if converted to Common Shares basis). The number of directors to be nominated by Xxxxxxxx (each, a “Xxxxxxxx Nominee”) shall be equal to the product of the number of directors the Board of Directors is composed of and the number of Common Shares owned by the Xxxxxxxx Group (calculated on an as-if converted to Common Shares basis) divided by the number of outstanding Common Shares (calculated on an as-if converted into Common Shares basis) and rounded up to the nearest whole number. Accordingly, each of the Shareholders agrees to act and vote from time to time so that on any election of directors by the shareholders of the Corporation, the Francisco Partners Nominees and the Xxxxxxxx Nominees to the Board of Directors are elected in accordance with this Section 2.2. The remaining directors of the Board of Directors shall be independent directors nominated by the Board of Directors. For the avoidance of doubt, as of the date of this Agreement, Francisco Partners II (Cayman), L.P. shall initially nominate four directors and Xxxxxxxx shall initially nominate three directors. In the event that Francisco Partners II (Cayman), L.P. requests that a Francisco Partners Nominee be removed or replaced as a director of the Corporation or that Xxxxxxxx requests that a Xxxxxxxx Nominee be removed or replaced as a director of the Corporation, then each of the Shareholders agrees to act and vote for such removal in accordance with this Section 2.2. Each Shareholder hereby grants Francisco Partners II (Cayman), L.P. and Xxxxxxxx a proxy, which shall be irrevocable to the fullest extent permissible by law and is coupled with an interest, to vote such Shareholder’s Shares in accordance with this Section 2.2. Notwithstanding the foregoing, no Shareholder shall be subject to the voting agreements in this Section 2.2 or elsewhere in this Agreement and the grant of proxy pursuant to this Section 2.2 shall become void if such Shareholder is PTIC or if such Shareholder, together with its Affiliates, holds less than 3% of the Common Shares (calculated on an as-if converted to Common Shares basis).

- 6 -

Each of the Francisco Partners Nominees and the Xxxxxxxx Nominees shall be an individual who is not disqualified under applicable law from acting as a director.

2.3 Notice of Directors Meetings

Notice of directors meetings shall be given, in writing, in accordance with the by-laws of the Corporation, and such notice shall also contain a statement as to the nature of the business proposed to be transacted at such meeting. Such notice shall be accompanied by all relevant documentation or information required for directors to make an informed decision regarding the business to be transacted.

2.4 Expenses of Directors

The Corporation shall reimburse all directors for all reasonable out-of-pocket expenses incurred in attending meetings of the Board of Directors or of any committee of the Board of Directors.

2.5 Board of Directors Committees

The Board of Directors shall maintain a standing committee to be known as the “Audit Committee” and a standing committee to be known as the “Compensation Committee”. At the option of Francisco Partners so long as the Francisco Partners Group is entitled to nominate at least one director to the Board of Directors pursuant to Section 2, at least one of the members of the Audit Committee, at least one of the members of the Compensation Committee, and at least one member of any other standing or ad hoc committee of the Board of Directors, shall be a Francisco Partners Nominee so long as the Francisco Partners Group holds 1/8th or more of the Shares subject to this Agreement.

2.6 Directors’ Liability Insurance

The Corporation will maintain directors’ liability insurance for each of the directors of the Corporation with coverage acceptable to the Board of Directors. The Corporation will not assign, transfer, dispose of, surrender, borrow upon or in any way encumber such insurance.

2.7 Board of Directors Observer

Each of Francisco Partners, Xxxxxxxx, Xxxxxx Xxxxxxx and EdgeStone, as the case may be, shall have the option at its sole discretion, at any time and from time to time, to designate an observer representative to receive notice of and attend meetings of the Board of Directors and meetings of any committee of the Board of Directors (the “Observer”), provided the Observer agrees to be bound by the confidentiality obligations set forth in Section 10.1. The Observer shall have no right to vote as a director of the Corporation with respect to any matter and shall not be included in any determination as to whether a quorum for any particular meeting exists. The minutes of each meeting of the Board of Directors or any such committee at which the Observer is present shall record that the Observer was present and acting in the capacity as an observer and not as a director. The Corporation shall pay the Observer’s reasonable out of pocket expenses incurred to attend any meeting of the Board of Directors or any committee of the Board of Directors. The rights of Francisco Partners in this Section 2.7 shall terminate once Francisco Partners is no longer entitled to nominate a director under Section 2.2, and the rights of

- 7 -

Xxxxxxxx in this Section 2.7 shall terminate once Xxxxxxxx is no longer entitled to nominate a director under Section 2.2. The rights of EdgeStone in this Section 2.7 shall terminate once the EdgeStone Group no longer holds at least 50% of the Common Shares (calculated on an as-if converted to Common Shares basis) held by the EdgeStone Group on the date hereof and reflected on Schedule D. The rights of Xxxxxx Xxxxxxx in this Section 2.7 shall terminate once the MS Investors no longer hold at least 25% of the Common Shares (calculated on an as-if converted to Common Shares basis) held by them on the date hereof and reflected on Schedule D.

2.8 Certain Matters Requiring Investors Majority Approval

Provided that members of the Francisco Partners Group hold, in the aggregate, at least 5% of the Common Shares (calculated on an as-if converted to Common Shares basis), notwithstanding any other provision of this Agreement, in addition to any other approvals that may be required by law or pursuant to the articles, by-laws or other organizational documents of the Corporation or any of the Subsidiaries, without the prior written consent of an Investors Majority, neither the Corporation shall nor shall it cause or permit any of the Subsidiaries to at any time take or agree or commit to take any action referred to in Appendix 2. It is acknowledged by the Parties that the provisions referenced in Appendix 2 are for the benefit of the Investors and may be amended or waived by the mutual agreement of the Corporation and an Investors Majority at any time.

2.9 Annual Budget

At least 30 days prior to the Corporation’s fiscal year-end, the Corporation shall submit the annual budget and business plan of the Corporation, including a detailed operating budget and a capital budget and the sources of financing thereof, with detailed supporting assumptions, to the Board of Directors for approval and thereafter from time to time as appropriate, any restatements or updates or deviations thereto to the extent they contain items or amounts not consistent with the normal course operations of the Business and previously approved budgets.

(c) The rights of the Investors and EdgeStone in this Section 2.10 shall terminate after a Qualified IPO. In addition, and if earlier, the rights of EdgeStone in this Section 2.10 shall terminate in the event that the EdgeStone Group no longer holds at least 50% of the Common Shares (calculated on an as-if converted to Common Shares basis) held by the EdgeStone Group on the date hereof and reflected on Schedule A.

In no event shall the Corporation be required to disclose information that it is prohibited from disclosing by contract (unless the applicable Investor enters into a confidentiality agreement that has the effect of eliminating such prohibition) or otherwise by law. The rights of the Investors and EdgeStone in this Section 2.11 shall terminate after a Qualified IPO. In addition, and if earlier, the rights of EdgeStone in this Section 2.11 shall terminate in the event that the EdgeStone Group no longer holds at least 50% of the Common Shares (calculated on an as-if converted to Common Shares basis) held by the EdgeStone Group on the date hereof and reflected on Schedule A.

Each Investor hereby grants Francisco Partners a proxy, which shall be irrevocable to the fullest extent permissible by law and is coupled with an interest, to vote such Investor’s Shares in accordance with this provision for so long as the Francisco Partners Group, excluding any Person to which Francisco Partners shall transfer all or substantially all of its assets, holds at least 30% of the Class 1 Shares.

ARTICLE 4

PRE-EMPTIVE RIGHTS

4.1 Exercise of Pre-Emptive Rights

(a) In the event that the Corporation or any Subsidiary proposes to undertake an issuance of New Securities (in a single transaction or a series of related transactions), it shall give to each Principal Shareholder (as such term is defined below) written notice of its intention to issue New Securities (the “Pre-Emptive Right Notice”), describing the amount and the type of New Securities and the price and the proposed closing date, upon which the Corporation proposes to issue the New Securities. For the purposes of this Section 4.1, the term “Principal Shareholders” means (i) each Shareholder who is a Shareholder on the date hereof, or any Permitted Transferee of such Shareholder, and (ii) each other Shareholder who, together with its Affiliates, holds not less than five percent (5%) of the Common Shares then outstanding (calculated on an as-if converted to Common Shares basis).

(b) Each Principal Shareholder shall have 15 Business Days from the date of receipt of any such Pre-Emptive Right Notice (the “Pre-Emptive Right Acceptance Period”) to agree in writing (i) to purchase up to its Pro Rata Share (as nearly as may be determined without division into fractions) of the New Securities (which for the purpose of this Article 4 shall be calculated based on holdings on the day immediately prior to the date of delivery by the Corporation of the Pre-Emptive Right Notice) for the price and on the other terms specified in the Pre-Emptive Right Notice and (ii) to purchase more than its Pro Rata Share (if available) up to a maximum number of the New Securities to be specified by such Principal Shareholder. Such right to purchase its Pro Rata Share of New Securities and, if desired, more than its Pro Rata Share shall be exercised by a Principal Shareholder by giving written notice (a “Pre-Emptive Right Acceptance Notice”) to the Corporation of such intention and stating therein the maximum number of New Securities it is willing to purchase (which number may be greater or less than its Pro Rata Share). If a Principal Shareholder fails to deliver such notice to the Corporation within the Pre-Emptive Right Acceptance Period, it shall be deemed to have declined to exercise its right to purchase any New Securities. If any Principal Shareholder does not give a Pre-Emptive Right Acceptance Notice within the Pre-Emptive Right Acceptance Period or specifies in its Pre-Emptive Right Acceptance Notice a number of Shares less than its Pro Rata Share, the resulting unaccepted New Securities shall be deemed to have been offered by the Corporation to such of the Principal Shareholders who specified in their respective Pre-Emptive Right Acceptance Notices a desire to acquire a number of the New Securities greater than their Pro Rata Share, and each such Principal Shareholder is, subject to the maximum number of the New Securities specified in its Pre-Emptive Right Acceptance Notice, entitled to acquire its Pro Rata Share (calculated relative to each of the Principal Shareholders wishing to purchase more than its Pro Rata Share) of the unaccepted New Securities based upon the number of Shares (calculated on an as-if converted to Common Shares basis) owned by such Principal Shareholders (calculated based on holdings on the

- 10 -

day immediately prior to the delivery of the Pre-Emptive Right Notice), as between themselves, or in such other proportion as such Principal Shareholders may agree in writing.

(c) The Corporation shall, from time to time, when requested to do so, advise each of the Principal Shareholders promptly of the names of the other Principal Shareholders who have accepted the Corporation’s offer as contained in a Pre-Emptive Right Notice and the number of New Securities in respect of which each such Principal Shareholder has accepted such offer.

(d) Any New Securities not accepted by the Principal Shareholders pursuant to Section 4.1(b) may be offered and sold by the Corporation to third parties for a period not to exceed 60 Business Days following the end of the Pre-Emptive Right Acceptance Period at the same or higher price and upon non-price terms not more favorable to the purchasers thereof than as specified in the Pre-Emptive Right Notice. In the event that the Corporation has not issued and sold such New Securities within such 60 Business Day period, then the Corporation shall not thereafter issue or sell any New Securities without again first offering such New Securities to the Principal Shareholders pursuant to this Article 4. If the Corporation offers any New Securities not taken up by Principal Shareholders pursuant to Section 4.1(b), the Corporation shall promptly notify the Principal Shareholders upon entering into one or more binding purchase agreement(s) during the 60 Business Day period referred to herein, including as to (i) the number of New Securities, if any, that the Corporation will issue (specifying respective numbers to be purchased by the Principal Shareholders on the one hand (if any) and by other Person(s) on the other hand), (ii) the material terms of such issuance(s) and (iii) the name(s) of the purchaser(s) of any New Securities to be issued (other than the Principal Shareholders).

(e) All sales of New Securities pursuant to this Section 4.1 shall be consummated contemporaneously at the offices of the Corporation as soon as is reasonably practicable on such date as the Board of Directors and the persons purchasing New Securities pursuant to this Section 4.1 may reasonably determine, but in no event later than the later of (i) 60 Business Days following the end of the Pre-Emptive Right Acceptance Period; or (ii) the fifth Business Day following the expiration or termination of all waiting periods under any competition or anti-combines legislation applicable to such issuance. The delivery of certificates or other instruments evidencing such New Securities shall be made by the Corporation on such date against payment of the purchase price therefor.

(f) The Corporation may issue New Securities without complying with the provisions of this Section 4.1 if the New Securities are Permitted Additional Securities.

4.2 Future Shares

The Corporation agrees that, as a condition precedent to the grant or issuance of any securities (including Convertible Securities) to a Person that, giving effect to such grant or issuance, would hold in excess of 2.5% of the outstanding Common Shares (calculated on as-if converted to Common Shares basis), whether now authorized or not, it will require that the

- 11 -

holder of such securities sign an Assumption Agreement and if the purchaser is a corporate entity, such agreement will also be signed by any Person who Controls such corporation; provided, however, that if any such grant or issuance is pursuant to the exercise or conversion of any Convertible Security granted or issued prior to the date of this Agreement, the Corporation shall only be required to use its commercially reasonable efforts to comply with the foregoing covenant.

ARTICLE 5

ARTICLE 6

RIGHTS OF FIRST REFUSAL, TAG-ALONG, AND DRAG-ALONG RIGHTS

6.1 Transfer Notice

In the event that any Shareholder (the “Transferring Shareholder”) receives from any Person, acting as principal and dealing at arm’s length with such Shareholder (the “Third Party Offeror”), a bona fide written offer to purchase (other than pursuant to a Transfer permitted by Section 5.2) Shares or Convertible Securities or other equity securities held by the Transferring Shareholder (the “Third Party Offer”), which the Transferring Shareholder wishes to accept (subject to compliance with Section 6.2 and 6.3), the Transferring Shareholder will give notice (the “Transfer Notice”) to the Corporation and to each of the Shareholders (other than any Shareholder that is also a Transferring Shareholder) (the “Other Shareholders”) setting forth:

(a) the identity of the Third Party Offeror;

(b) if the Third Party Offeror is a corporation, the names of the principal shareholders, directors and officers of the Third Party Offeror;

(c) the number and classes of Shares or Convertible Securities or other equity securities proposed to be sold by the Transferring Shareholder (the “Offeror’s Securities”);

(d) the price of and terms of payment for the Offeror’s Securities; and

(e) a summary of any other material terms for such sale including the proposed closing date.

The Transfer Notice shall contain an offer to sell all of the Offeror’s Securities to the Corporation first and then the Other Shareholders (as set out in Section 6.2) at the price and on the terms set forth in the Transfer Notice. The Transfer Notice shall include a full and complete copy of the written offer delivered by the Third Party Offeror. In all circumstances the proposed consideration for any Offeror’s Securities must be in cash and/or Marketable Securities. The offer contained in the Transfer Notice shall be irrevocable except with the consent of Corporation or the Other Shareholders, as applicable, and shall be open for acceptance for a

- 14 -

period of 19 Business Days after the date upon which the Transfer Notice was received by the Corporation and 20 Business Days after the date upon which the Transfer Notice was received by the Other Shareholders (each, an “Acceptance Period”).

All Transfer Notices and Drag-Along Offers (as defined in Section 6.4) given under this Article 6 must be given concurrently to all Other Shareholders and the Corporation.

6.2 Rights of First Refusal

Upon receipt of a Transfer Notice and subject to all of the provisions of this Section 6.2, the Corporation and the Other Shareholders shall have the following rights and options:

(a) The Corporation shall have the first right to purchase any or all of the Offeror’s Securities if it gives a notice in writing (an “Acceptance Notice”) accepting the offer contained in the Transfer Notice and specifying the number of the Offeror’s Securities it wishes to acquire.

(b) If the Corporation does not give an Acceptance Notice to purchase any or all of the Offeror’s Securities at least one Business Day prior to the expiration of the Acceptance Period, each of the Other Shareholders shall have the right to purchase up to its Pro Rata Share of the Offeror’s Securities not to be purchased by the Corporation at the price and on the terms and conditions contained in the Transfer Notice.

(c) Subject to Sections 6.2(a) and (b), within the Acceptance Period, each of the Other Shareholders may give to the Transferring Shareholder an Acceptance Notice accepting the offer contained in the Transfer Notice and specifying the maximum number of the Offeror’s Securities not to be purchased by the Corporation that it wishes to acquire (which number may be greater than or less than its Pro Rata Share). Each of the Other Shareholders shall have the right to purchase up to its Pro Rata Share of the Offeror’s Securities not to be purchased by the Corporation (which for purposes of this Section 6.2 shall be calculated based on holdings on the day immediately prior to the delivery of the Transfer Notice), as nearly as may be determined without division into fractions and, if available, a number of the Offeror’s Securities not to be purchased by the Corporation greater than its Pro Rata Share up to a stated maximum. Any Other Shareholder who does not give an Acceptance Notice within the Acceptance Period shall be deemed to have declined to purchase any of the Offeror’s Securities. If any Other Shareholder does not give an Acceptance Notice within the Acceptance Period or specifies in its Acceptance Notice a number of Shares less than its Pro Rata Share, the resulting unaccepted Offeror’s Securities shall be deemed to have been offered by the Transferring Shareholder to such of the Other Shareholders who specified in their respective Acceptance Notices a desire to acquire a number of the Offeror’s Securities not to be purchased by the Corporation greater than their Pro Rata Share, and each such Other Shareholder is, subject to the maximum number of the Offeror’s Securities specified in its Acceptance Notice, entitled to acquire its Pro Rata Share (calculated relative to each of the other Shareholders wishing to purchase more than its Pro Rata Share) of the unaccepted Offeror’s Securities based upon the number of Shares

- 15 -

(calculated on an as-if converted to Common Shares basis) owned by such Other Shareholders (calculated based on holdings on the day immediately prior to the delivery of the Transfer Notice), as between themselves, or in such other proportion as such Other Shareholders may agree in writing. If (i) the Corporation gives notice pursuant to Section 6.2(a) to purchase all of the Offeror’s Securities or (ii) the Other Shareholders, or any of them, give Acceptance Notices within the Acceptance Period confirming their agreement to purchase all of the Offeror’s Securities not to be purchased by the Corporation, the sale of the Offeror’s Securities to the Corporation and/or such Other Shareholders shall be completed within 15 Business Days of the expiry of the Acceptance Period.

(d) If both (i) the Corporation does not give an Acceptance Notice to purchase all of the Shares at least one Business Day prior to the expiry of the Acceptance Period and (ii) the Other Shareholders do not give notice of acceptance prior to the expiry of the Acceptance Period which would result in the purchase of all, but not less than all, of the Offeror’s Securities not to be purchased by the Corporation, the Transferring Shareholder will, notwithstanding any notices of acceptance of the Offeror’s Securities by the Corporation or any Other Shareholders, subject to the provisions of Section 6.3, have the right to sell the Offeror’s Securities to the Third Party Offeror for a period of 60 Business Days from the expiration of the Acceptance Period for a price not less than that provided for in the Transfer Notice and on terms and conditions not materially more favorable to the Third Party Offeror than those set out in the Transfer Notice, provided that such Third Party Offeror first executes and delivers to the Corporation an Assumption Agreement. If such Transfer is not consummated within such 60 Business Day period, the Transferring Shareholder will not Transfer any of the Offeror’s Securities without again complying with all of the provisions of Section 6.1 and Section 6.2.

(e) Any Transfer entered into in connection with this Section 6.2 shall not provide a Collateral Benefit to any Shareholder or any Affiliate or Related Party thereof.

(f) For greater certainty, no rights shall arise under this Article 6 in respect of any purchases by Other Shareholders pursuant to the exercise of rights under this section.

(g) The provisions of Section 6.1 and 6.2 shall not apply to the Transfer of any Shares or Convertible Securities pursuant to the provisions of Section 6.3 or 6.4 and which are exercised in accordance with the terms thereof.

(h) Each Other Shareholder may assign its right to exercise its right of first refusal under this 6.2, in whole or in part, to any of its Affiliates, or, in the case of the Francisco Partners Group, the MS Investors, the Xxxxxxxx Group or the EdgeStone Group to any member or members of the Francisco Partners Group or the MS Investors or any MS Affiliate or the Xxxxxxxx Group or the EdgeStone Group, as applicable, provided such member or members (and Controlling Persons in the case of the Xxxxxxxx Group) have first entered into an Assumption Agreement.

- 16 -

6.3 Tag-Along Rights

Upon receipt of a Transfer Notice, any Other Shareholder(s) may elect to participate in the proposed Transfer by delivering written notice to the Corporation and Transferring Shareholder within the Acceptance Period. Each of the Other Shareholders so electing will be entitled to sell in the contemplated Transfer, the same proportion (calculated on an as-if-converted to Common Shares basis) of the Shares and Convertible Securities held by each such Other Shareholder, respectively, as the proportion of the Transferring Shareholder’s total holdings which the Transferring Shareholder proposes to sell pursuant to the Transfer Notice (calculated on an as-if-converted to Common Shares basis), on the same terms (other than price) set forth in the Transfer Notice, and at a price determined as follows:

(a) if the Transferring Shareholder is proposing to sell Common Shares:

(i) any Common Shares to be sold by an Other Shareholder shall be sold at the same price per share as the Common Shares proposed to be sold by the Transferring Shareholder, as set forth in the Transfer Notice;

(ii) any Class 1 Shares to be sold by an Other Shareholder shall be sold at a price per share equal to the TR Value calculated based on a value per share equal to the price per Common Share proposed by the Transferring Shareholder;

(iii) any Convertible Securities to be sold by an Other Shareholder shall be sold at a price per Convertible Security equal to: (A) the value of the Common Shares underlying such Convertible Security, where such Common Shares are valued at the same price per share as the Common Shares proposed to be sold by the Transferring Shareholder, as set forth in the Transfer Notice, less (B) any amount payable by the holder of the Convertible Securities on the exercise, exchange or conversion thereof;

(b) if the Transferring Shareholder is proposing to sell Class 1 Shares:

(i) any Common Shares to be sold by an Other Shareholder shall be valued at a price per share equal to the price per Class 1 Share proposed to be sold by the Transferring Shareholder, as set forth in the Transfer Notice, divided by the number of Common Shares into which a Class 1 Share could convert at the Conversion Value for the Class 1 Shares then in effect (the “Notional Common Share Value”);

(ii) any Class 1 Shares to be sold by an Other Shareholder shall be sold at the same price per share as the Class 1 Shares proposed to be sold by the Transferring Shareholder, as set forth in the Transfer Notice; and

(iii) any Convertible Securities to be sold by an Other Shareholder shall be sold at a price per Convertible Security equal to: (A) the Notional Common Share Value multiplied by the number of Common Shares underlying such Convertible Security, less (B) any amount payable by the holder of the Convertible Securities on the exercise, exchange or conversion thereof.

- 17 -

(c) if the Transferring Shareholder is proposing to sell Convertible Securities (other than Class 1 Shares), only Shareholders holding the same type of Convertible Securities with identical provisions (other than the number of underlying securities in respect of which the Convertible Securities are exercisable, exchangeable or convertible) as the Convertible Securities which are the subject of the Transfer Notice may exercise tag-along rights pursuant to this Section 6.3, and any such Convertible Securities shall be sold at the same price for each of the Convertible Securities (based on a unit basis) proposed to be sold by the Transferring Shareholder, as set forth in the Transfer Notice. The Shareholders shall have no right to exercise tag-along rights pursuant to this Section 6.3(c) in respect of Common Shares, Class 1 Shares or other Convertible Securities which are not identical to the Convertible Securities which are the subject of the Transfer Notice.

For greater certainty, no rights shall arise under this Section 6.3 as a result of any purchases in accordance with the exercise of rights of first refusal under Section 6.2 nor shall the provisions of Sections 6.1 and 6.3 apply to the Transfer of any Shares or Convertible Securities to which the provisions of Section 6.4 apply and which are exercised in accordance with the terms thereof.

Notwithstanding the foregoing, if any transaction or series of transactions contemplated by this Section 6.3 would result in a Change of Control Event, the Shareholders shall not complete the proposed transaction unless the aggregate consideration payable by the Third Party Offeror pursuant to this Section 6.3 is allocated in accordance with the Articles of Amendment as if it were a “Change of Control Event” thereunder.

Any purchase and sale agreement entered into in conjunction with this Section 6.3 shall:

(a) contain only several (not joint and several) representations, warranties and covenants from any holder of Shares or Convertible Securities with recourse limited to that Shareholder’s pro rata portion of the aggregate purchase price to all Shareholders;

(b) contain a limitation on the liability each Shareholder assumes, with respect to all indemnities, if any, provided to the Third Party Offeror, to that Shareholder’s pro rata portion of the aggregate purchase price to all Shareholders;

(c) not require the Shareholders that participate in the transaction pursuant to this Section 6.3 to provide representations or warranties or covenants related to the Corporation but shall require them to provide typical title, ownership and authority to sell representations;

(d) not provide a Collateral Benefit to any Shareholder or any Affiliate or Related Party thereof (other than the right to receive the purchase price calculated in accordance with the provisions above); and

- 18 -

(e) be conditional upon completion of the purchase by the Third Party Offeror of the Shares or Convertible Securities held by the Transferring Shareholder which are subject to the Transfer Notice.

Any Shareholder not giving notice within the Acceptance Period under this Section 6.3 shall be deemed to have declined to exercise its tag-along rights under this Section 6.3

If any of the Other Shareholders exercises its rights hereunder, the purchase and sale of the Shares and Convertible Securities of the Corporation to the Third Party Offeror pursuant to the Transfer Notice shall be completed at the same time as the purchase and sale of the Offeror’s Securities and as part of the same closing.

To the extent that the Other Shareholders do not exercise their rights hereunder, the Transferring Shareholder shall be entitled to sell the Shares specified in the Transfer Notice in accordance with the terms thereof for a period of 60 Business Days after the expiry of the Acceptance Period. If the sale is not completed within such 60 Business Day period, the provisions of Article 6 shall again apply to any proposed sale of Shares and so on from time to time.

6.4 Drag-Along Rights

(a) If any Shareholder receives from a third party (the “Third Party”) acting as principal and dealing at arm’s length with the Transferring Shareholder, a bona fide written offer (the “Third Party Offer”) to purchase all (but not less than all) of the Shares and Convertible Securities (which transaction may include, without limitation, an offer pursuant to a merger, amalgamation, arrangement, capital reorganization, consolidation or similar transaction), and the Third Party Offer is accepted by either (i) Shareholders holding at least 50% of the votes attached to the outstanding Shares and Convertible Securities held by parties to this Agreement (including votes that attach to securities issuable upon exercise of Convertible Securities) so long as the Third Party Offer is a Qualifying Offer (as defined hereinafter), or (ii) an Investors Majority (the “Accepting Shareholders”), the Accepting Shareholders shall be entitled to obtain from the Third Party an offer (a “Drag-Along Offer”) to purchase all of the Shares and Convertible Securities of the Corporation held by the Shareholders other than the Accepting Shareholders (the “Forced Shareholders”) on the same terms and conditions as contained in the Third Party Offer, subject to the provisions of Section 6.4(b). Notwithstanding the foregoing, Xxxxxxxx shall not be required to accept a Drag Along Offer prior to the date one year from the date of this Agreement. If the consideration to be received by the Forced Shareholders in the Drag-Along Offer includes consideration other than cash or cash equivalents, the Drag-Along Offer shall, if necessary, include a valuation prepared in accordance with Section 6.5. The Drag-Along Offer shall be irrevocable. For the purposes of this Agreement, a “Qualifying Offer” means a Third Party Offer: (i) received within two years from the date hereof, and (ii) pursuant to which the holders of the Class 1 Shares purchased by the Investors pursuant to the Subscription Agreement would be entitled to receive aggregate proceeds, payable in cash, equal to not less than $2,000 for each Class 1 Share held by such Persons.

- 19 -

(b) The Drag-Along Offer shall:

(i) not provide a Collateral Benefit to any Shareholder or any Affiliate or Related Party thereof (other than, to the extent that proceeds are distributed in accordance with the Articles of Amendment, in the case of any holder of Class 1 Shares, the right of such holder to receive the TR Value)

(ii) require each of the Shareholders to provide such representations, warranties and indemnities as are customary and reasonably requested by the Third Party; and

(iii) provide that each such Shareholder’s liability for representations, warranties and indemnities provided to the Third Party shall be, in any event, limited to such Shareholder’s pro rata share of the proceeds received from the transaction.

(c) The Forced Shareholders shall be obliged to accept the Drag-Along Offer (or otherwise take all necessary action to cause the Corporation to consummate the proposed transaction, as applicable) within 3 Business Days of receipt or such other period agreeable to the Accepting Shareholders. The acceptance of the Drag-Along Offer shall be made in writing and a copy of the acceptance (or of the accepted Drag-Along Offer) shall be delivered to the Accepting Shareholders within such 3 Business Day period.

(d) If any of the Forced Shareholders do not deliver an acceptance of the Drag-Along Offer within the 3 Business Day period referred to above, the Secretary of the Corporation (the “Drag-Along Offer Attorney”) shall be entitled to, and the Shareholders acknowledge, agree and authorize the Drag-Along Offer Attorney to, accept the Drag-Along Offer on behalf of such Forced Shareholders and to deliver the acceptance to the Third Party and, for such purpose, each of the Forced Shareholders hereby appoints the Drag-Along Offer Attorney as its attorney, on the terms set forth in Section 11.2, with full power of substitution, in the name of the Forced Shareholder to accept the Drag-Along Offer and to execute and deliver all documents and instruments to give effect to such acceptance and to establish a binding contract of purchase and sale between the Forced Shareholder and the Third Party with respect to all of the Shares and other securities held by the Forced Shareholder and to execute and deliver all deeds, transfers, assignments and assurances necessary to effectively Transfer such Shares to the Third Party. Each of the Shareholders agrees that it will perform the agreement resulting from acceptance of the Drag-Along Offer in accordance with its terms and will ratify and confirm all that the Drag-Along Offer Attorney may do or cause to be done pursuant to the foregoing. Notwithstanding that certificates or instruments evidencing the Shares or Convertible Securities may not have been delivered by any Forced Shareholder to the Third Party, upon completion of the Third Party’s obligations under the Third Party Offer:

(i) the purchase of Shares or Convertible Securities from the Forced Shareholder shall be deemed to have been fully completed and the records of the Corporation may be amended accordingly;

- 20 -

(ii) all right, title, benefit and interest, both at law and in equity, in and to the Shares or Convertible Securities shall be conclusively deemed to have been transferred and assigned to and become vested in the Third Party; and

(iii) all right, title, benefit and interest of such Forced Shareholder and of any other Person (other than the Third Party) having an interest in such Shares, legal or equitable, in any capacity whatsoever shall cease.

(e) The purchase and sale of Shares and Convertible Securities in accordance with the provisions of the Drag-Along Offer shall be completed at the same time and on the same terms as the completion of the purchase and sale of Shares and Convertible Securities and/or other securities between the Accepting Shareholders and the Third Party in accordance with the Third Party Offer and as part of the same closing within 60 Business Days after expiry of the 3 Business Day period referred to in Section 6.4(c).

(f) In the event that a Drag-Along Offer is made in connection with a Third Party Offer and the Shares held by the Accepting Shareholders and the Forced Shareholders constitute less than all of the Shares of the Corporation, the Corporation agrees to take all steps necessary to facilitate the Third Party’s compulsory acquisition pursuant to Part XVII of the CBCA, if applicable, of all Shares of the Corporation not already purchased by the Third Party.

6.5 Valuation of Non-Cash Consideration

Any valuation of non-cash consideration included in a Third Party Offer will be, in the case of: (i) Marketable Securities, calculated based on the weighted average closing price of those securities on the exchange or market on which the securities are primarily traded for the twenty trading days ended at the close of business on the day prior to delivery of the applicable notice, and (ii) other non-cash consideration, the fair market value thereof as determined in good faith by the Board of Directors, provided, that, if any Shareholder objects to any such determination within ten (10) days of receiving notice thereof, such fair market value will be determined by an independent investment banking or business valuation firm mutually agreeable to the Board of Directors and an Investors Majority (the costs of which shall be borne by the Corporation).
