5.6 Delivery of Merge Common Shares; Effect of Exercise

Promptly after the receipt of the certificates representing the Exchangeable Shares which the Beneficiary desires Merge to purchase under the Exchange Right, together with such documents and instruments of transfer and a duly completed form of notice of exercise of the Exchange Right (and payment of taxes, if any payable as contemplated by section 5.8 or evidence thereof), duly endorsed for transfer to Merge, the Trustee shall notify Merge and Matsub of its receipt of the same, which notice to Merge and Matsub shall constitute exercise of the Exchange Right by the Trustee on behalf of the holder of such Exchangeable Shares, and Merge shall deliver or cause to be delivered to the Trustee, for delivery to the Beneficiary of such Exchangeable Shares (or to such other persons, if any, properly designated by such Beneficiary) the number of Merge Common Shares issuable in connection with the exercise of the Exchange Right, and on the applicable payment date cheques for the balance, if any, of the total purchase price therefor without interest (but less any amounts withheld pursuant to section 5.13); provided, however, that no such delivery shall be made unless and until the Beneficiary requesting the same shall have paid (or provided evidence satisfactory to the Trustee, Matsub and Merge of the payment of) the taxes (if any) payable as contemplated by section 5.8 of this Agreement. Immediately upon the giving of notice by the Trustee to Merge and Matsub of the exercise of the Exchange Right as provided in this section 5.6, the closing of the transaction of purchase and sale contemplated by the Exchange Right shall be deemed to have occurred and the holder of such Exchangeable Shares shall be deemed to have transferred to Merge all of such holder’s right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate and shall cease to be a holder of such Exchangeable Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive his proportionate part of the total purchase price therefor, unless the requisite number of Merge Common Shares is not allotted, issued and delivered by Merge to the Trustee within five Business Days of the date of the giving of such notice by the Trustee or the balance of the purchase price, if any, is not paid by Merge on the applicable payment date therefor, in which case the rights of the Beneficiary shall remain unaffected until such Merge Common Shares are so allotted, issued and delivered, and the balance of the purchase price, if any, has been paid, by Merge. Upon delivery by Merge to the Trustee of such Merge Common Shares, and the balance of the purchase price, if any, the Trustee shall deliver such Merge Common Shares to such Beneficiary (or to such other persons, if any, properly designated by such Beneficiary). Concurrently with such Beneficiary ceasing to be a holder of Exchangeable Shares, the Beneficiary shall be considered and deemed for all purposes to be the holder of the Merge Common Shares delivered to it pursuant to the Exchange Right.

5.7 Exercise of Exchange Right Subsequent to Retraction

In the event that a Beneficiary has exercised its right under Article 6 of the Share Provisions to require Matsub to redeem any or all of the Exchangeable Shares held by the Beneficiary (the “Retracted Shares” ) and is notified by Matsub pursuant to section 6.6 of the Share Provisions that Matsub will not be permitted as a result of solvency requirements of applicable law to redeem all such Retracted Shares, and provided that Merge Newco shall not have exercised the Retraction Call Right with respect to the Retracted Shares and that the Beneficiary has not revoked the retraction request delivered by the Beneficiary to Matsub pursuant to section 6.1 of the Share Provisions and provided further that the Trustee has received written notice of same from Matsub or Merge, the retraction request will constitute and will be deemed to constitute notice from the Beneficiary to the Trustee instructing the Trustee to exercise the Exchange Right with respect to those Retracted Shares that Matsub is unable to redeem. In any such event, Matsub hereby agrees with the Trustee and in favour of the Beneficiary promptly to forward or cause to be forwarded to the Trustee all relevant materials delivered by the Beneficiary to Matsub or to the transfer agent of the Exchangeable Shares (including without limitation, a copy of the retraction request delivered pursuant to section 6.1 of the Share Provisions) in connection with such proposed redemption of the Retracted Shares and the Trustee will thereupon exercise the Exchange Right with respect to the Retracted Shares that Matsub is not permitted to redeem and will require Merge to purchase such shares in accordance with the provisions of this Article 5.

Upon any sale of Exchangeable Shares to Merge pursuant to the Exchange Right or the Automatic Exchange Rights, the share certificate or certificates representing Merge Common Shares to be delivered in connection with the payment of the total purchase price therefor shall be issued in the name of the Beneficiary of the Exchangeable Shares so sold or in such names as such Beneficiary may otherwise direct in writing without charge to the holder of the Exchangeable Shares so sold; provided, however, that such Beneficiary (a) shall pay (and none of Merge, Matsub or the Trustee shall be required to pay) any documentary, stamp, transfer or other taxes that may be payable in respect of any transfer involved in the issuance or delivery of such shares to a person other than such Beneficiary or (b) shall have evidenced to the satisfaction of the Trustee, Merge and Matsub that such taxes, if any, have been paid.

As soon as practicable following the occurrence of an Insolvency Event or any event that with the giving of notice or the passage of time or both would be an Insolvency Event, Matsub and Merge shall give written notice thereof to the Trustee. As soon as practicable following the receipt of notice from Matsub and Merge of the occurrence of an Insolvency Event, or upon the Trustee becoming aware of an Insolvency Event, the Trustee will mail to each Beneficiary, at the expense of Merge (such funds to be received in advance), a notice of such Insolvency Event in the form provided by Merge, which notice shall contain a brief statement of the rights of the Beneficiaries with respect to the Exchange Right.

5.10 Qualification of Merge Common Shares

Merge covenants that if any Merge Common Shares to be issued and delivered pursuant to the Exchange Right or the Automatic Exchange Rights require registration or qualification with or approval of or the filing of any document, including any prospectus or similar document, or the taking of any proceeding with or the obtaining of any order, ruling or consent from any governmental or regulatory authority under any Canadian or United States federal, provincial or state law or regulation or pursuant to the rules and regulations of any regulatory authority or the fulfillment of any other Canadian or United States federal, provincial or state legal requirement before such shares may be issued and delivered by Merge to the initial holder thereof or in order that such shares may be freely traded thereafter (other than any restrictions of general application on transfer by reason of a holder being a “control person” of Merge for purposes of Canadian provincial securities law or an “affiliate” of Merge for purposes of United States federal or state securities law), Merge will in good faith expeditiously take all such actions and do all such things as are necessary or desirable to cause such Merge Common Shares to be and remain duly registered,

qualified or approved. Merge will in good faith expeditiously take all such actions and do all such things as are reasonably necessary or desirable to cause all Merge Common Shares to be delivered pursuant to the Exchange Right or the Automatic Exchange Rights to be listed, quoted or posted for trading on all stock exchanges and quotation systems on which outstanding Merge Common Shares have been listed by Merge and remain listed and are quoted or posted for trading at such time.

Merge will provide or cause to be provided to the Trustee such legal opinions, certificates, documents and other instruments as the Trustee may from time to time reasonably request to demonstrate compliance with this section 5.10.

Merge hereby represents, warrants and covenants that the Merge Common Shares issuable as described herein will be duly authorized and validly issued as fully paid and non-assessable and shall be free and clear of any lien, claim or encumbrance.

5.11 Merge Common Shares

5.12 Automatic Exchange on Liquidation of Merge

(a)
Merge will give the Trustee written notice of each of the following events at the time set forth below:

(i)
in the event of any determination by the Board of Directors of Merge to institute voluntary liquidation, dissolution or winding-up proceedings with respect to Merge or to effect any other distribution of assets of Merge among its shareholders for the purpose of winding up its affairs, at least 60 days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; and

(ii)
as soon as practicable following the earlier of (A) receipt by Merge of notice of, and (B) Merge otherwise becoming aware of, any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of Merge or to effect any other distribution of assets of Merge among its shareholders for the purpose of winding up its affairs, in each case where Merge has failed to contest in good faith any such proceeding commenced in respect of Merge within 30 days of becoming aware thereof.

(b)
As soon as practicable following receipt by the Trustee from Merge of notice of any event (a “Liquidation Event” ) contemplated by section 5.12 (a) (i) or 5.12 (a) (ii) above, the Trustee will give notice thereof to the Beneficiaries. Such notice shall be provided to the Trustee by Merge and shall include a brief description of the automatic exchange of Exchangeable Shares for Merge Common Shares provided for in section 5.12(c).

(c)
In order that the Beneficiaries will be able to participate on a pro rata basis with the holders of Merge Common Shares in the distribution of assets of Merge in connection with a Liquidation Event, on the fifth Business Day prior to the effective date (the “Liquidation Event Effective Date” ) of a Liquidation Event all of the then outstanding Exchangeable Shares shall be automatically exchanged for Merge Common Shares. To effect such automatic exchange, Merge shall purchase on the fifth Business Day prior to the Liquidation Event Effective Date each Exchangeable Share then outstanding and held by Beneficiaries, and each Beneficiary shall sell the Exchangeable Shares held by it at such time, for a purchase price per share

equal to (a) the Current Market Price of a Merge Common Share on the fifth Business Day prior to the Liquidation Event Effective Date, which shall be satisfied in full by Merge issuing to the Beneficiary one Merge Common Share, and (b) to the extent not paid by Matsub, an additional amount equal to and in satisfaction of the full amount of all declared and unpaid dividends on each such Exchangeable Share held by such holder on any dividend record date which occurred prior to the date of the exchange (less any applicable withholding taxes). Merge shall provide the Trustee with an Officer’s Certificate in connection with each automatic exchange setting forth the calculation of the purchase price for each Exchangeable Share.

(d)
On the fifth Business Day prior to the Liquidation Event Effective Date, the closing of the transaction of purchase and sale contemplated by the automatic exchange of Exchangeable Shares for Merge Common Shares shall be deemed to have occurred, and each Beneficiary shall be deemed to have transferred to Merge all of the Beneficiary’s right, title and interest in and to such Beneficiary’s Exchangeable Shares and the related interest in the Trust Estate, any right of each such Beneficiary to receive declared and unpaid dividends from Matsub shall be deemed to be satisfied and discharged and each such Beneficiary shall cease to be a holder of such Exchangeable Shares and Merge shall issue to the Beneficiary the Merge Common Shares issuable upon the automatic exchange of Exchangeable Shares for Merge Common Shares and on the applicable payment date shall deliver to the Trustee for delivery to the Beneficiary a cheque for the balance, if any, of the total purchase price for such Exchangeable Shares without interest but less any amounts withheld pursuant to section 5.13. Concurrently with such Beneficiary ceasing to be a holder of Exchangeable Shares, the Beneficiary shall be considered and deemed for all purposes to be the holder of the Merge Common Shares issued pursuant to the automatic exchange of Exchangeable Shares for Merge Common Shares and the certificates held by the Beneficiary previously representing the Exchangeable Shares exchanged by the Beneficiary with Merge pursuant to such automatic exchange shall thereafter be deemed to represent Merge Common Shares issued to the Beneficiary by Merge pursuant to such automatic exchange. Upon the request of a Beneficiary and the surrender by the Beneficiary of Exchangeable Share certificates deemed to represent Merge Common Shares, duly endorsed in blank and accompanied by such instruments of transfer as Merge may reasonably require, Merge shall deliver or cause to be delivered to the Beneficiary certificates representing Merge Common Shares of which the Beneficiary is the holder.

5.13 Withholding Rights

Merge, Matsub and the Trustee shall be entitled to deduct and withhold from any consideration otherwise payable under this Agreement to any holder of Exchangeable Shares or Merge Common Shares such amounts as Merge, Matsub or the Trustee is required to deduct and withhold with respect to such payment under the Income Tax Act (Canada), the United States Internal Revenue Code of 1986 or any provision of provincial, state, local or foreign tax law, in each case as amended or succeeded. The Trustee may act on the advice of counsel with respect to such matters. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes as having been paid to the holder of the shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. To the extent that the amount so required to be deducted or withheld from any payment to a holder exceeds the cash portion of the consideration otherwise payable to the holder, Merge, Matsub and the Trustee are hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to Merge, Matsub or the Trustee, as the case may be, to enable it to comply with such deduction or withholding requirement and Merge, Matsub or the Trustee shall notify the holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale. Merge represents and warrants that, based upon facts currently known to it, it has no current intention, as at the date of this Agreement, to deduct or withhold from any dividend paid to holders of Exchangeable Shares any amounts under the United States Internal Revenue Code of 1986.

ARTICLE 6

taking such other actions and doing such other things as are specifically provided in this Agreement.

In the exercise of such rights, powers, duties and authorities the Trustee shall have (and is granted) such incidental and additional rights, powers, duties and authority not in conflict with any of the provisions of this Agreement as the Trustee, acting in good faith and in the reasonable exercise of its discretion, may deem necessary,

appropriate or desirable to effect the purpose of the Trust. Any exercise of such discretionary rights, powers, duties and authorities by the Trustee shall be final, conclusive and binding upon all persons.

In connection therewith, the Trustee may obtain the advice and assistance of such experts or advisors as the Trustee considers necessary or advisable (who may be experts or advisors to Merge or Matsub). If requested by the Trustee, Merge or Matsub shall retain qualified experts or advisors for the purpose of providing such tax advice or assistance.

No Beneficiary shall have the right to institute any action, suit or proceeding or to exercise any other remedy authorized by this Agreement for the purpose of enforcing any of its rights or for the execution of any trust or power hereunder unless the Beneficiary has requested the Trustee to take or institute such action, suit or proceeding and furnished the Trustee with the funding, security or indemnity referred to in section 7.6 and the Trustee shall have failed to act within a reasonable time thereafter. In such case, but not otherwise, the Beneficiary shall be entitled to take proceedings in any court of competent jurisdiction such as the Trustee might have taken; it being understood and intended that no one or more Beneficiaries shall have any right in any manner whatsoever to affect, disturb or prejudice the rights hereby created by any such action, or to enforce any right hereunder or the Voting Rights, the Exchange Rights or the Automatic Exchange Rights except subject to the conditions and in the manner herein provided, and that all powers and trusts hereunder shall be exercised and all proceedings at law shall

Merge and Matsub jointly and severally agree to indemnify and hold harmless the Trustee and each of its directors, officers, employees and agents appointed and acting in accordance with this Agreement (collectively, the “Indemnified Parties” ) against all claims, losses, damages, reasonable costs, penalties, fines and reasonable expenses (including reasonable expenses of the Trustee’s legal counsel) which, without fraud, negligence, recklessness, wilful misconduct or bad faith on the part of such Indemnified Party, may be paid, incurred or suffered by the Indemnified Party by reason or as a result of the Trustee’s acceptance or administration of the Trust, its compliance with its duties set forth in this Agreement, or any written or oral instruction delivered to the Trustee by Merge or Matsub pursuant hereto.

In no case shall Merge or Matsub be liable under this indemnity for any claim against any of the Indemnified Parties unless Merge and Matsub shall be notified by the Trustee of the written assertion of a claim or of any action commenced against the Indemnified Parties, promptly after any of the Indemnified Parties shall have received any such written assertion of a claim or shall have been served with a summons or other first legal process giving information as to the nature and basis of the claim. Subject to (ii) below, Merge and Matsub shall be entitled to participate at their own expense in the defence and, if Merge and Matsub so elect at any time after receipt of such notice, either of them may assume the defence of any suit brought to enforce any such claim.

This indemnity shall survive the termination of this Agreement and the resignation or removal of the Trustee.

9.2 Limitation of Liability

The Trustee shall not be held liable for any loss which may occur by reason of depreciation of the value of any part of the Trust Estate or any loss incurred on any investment of funds pursuant to this Agreement, except to the extent that such loss is attributable to the fraud, negligence, recklessness, wilful misconduct or bad faith on the part of the Trustee.

10.3 Successor Trustee

Any successor trustee appointed as provided under this Agreement shall execute, acknowledge and deliver to Merge and Matsub and to its predecessor trustee an instrument accepting such appointment. Thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with the like effect as if originally named as trustee in this Agreement. However, on the written request of Merge and Matsub or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of this Agreement, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon the request of any such successor trustee, Merge, Matsub and such predecessor trustee shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers.

(a)
such other person or continuing corporation (herein called the “Merge Successor” ), by operation of law, becomes, without more, bound by the terms and provisions of this Agreement or, if not so bound, executes, prior to or contemporaneously with the consummation of such transaction, a trust agreement supplemental hereto and such other instruments (if any) as are satisfactory to the Trustee, acting reasonably, and in the opinion of legal counsel to the Trustee are reasonably necessary or advisable to evidence the assumption by the Merge Successor of liability for all moneys payable and property deliverable hereunder and the covenant of such Merge Successor to pay and deliver or cause to be delivered the same and its agreement to observe and perform all the covenants and obligations of Merge under this Agreement; and
