(ii) No step has been taken, no event has occurred and no condition or circumstance exists that has resulted in or could reasonably be expected to result in any Cedara Plan being ordered or required to be terminated or wound up in whole or in part or having its registration under applicable Laws refused or revoked, or being placed under the administration of any trustee or receiver or regulatory authority or being required to pay any material Taxes, fees, penalties or levies under applicable Laws. There are no actions, suits, claims (other than routine claims for payment of benefits in the ordinary course), trials, demands, investigations, arbitrations or other proceedings which are pending or threatened in respect of any of Cedara Plans or their assets which individually or in the aggregate would have a Material Adverse Effect on Cedara or a Cedara Material Subsidiary.

To the knowledge of Cedara, no fact or circumstance exists that could adversely affect the existing tax status of a Cedara Plan.

(v) All obligations of Cedara or a Cedara Subsidiary regarding Cedara Plans have been satisfied in all material respects. All contributions or premiums required to be made by Cedara and/or a Cedara Material Subsidiary, as the case may be, under the terms of each Cedara Plan or by applicable Laws have been made in a timely fashion in accordance with applicable Laws and the terms of the Cedara Plans.

(vii) There have been no improper withdrawals, applications or transfers of assets from any Cedara Plan or the trusts or other funding media relating thereto that remain outstanding and unremedied, and neither Cedara, nor any Cedara Subsidiary, nor any of their respective agents has been in breach of any fiduciary obligation with respect to the administration of Cedara Plans or the trusts or other funding media relating thereto.

(viii) No insurance policy or any other contract or agreement affecting any Cedara Plan requires or permits a retroactive increase in premiums or payments due thereunder.

(ix) All Cedara Plans intended to be tax-qualified in the United States have been the subject of determination letters from the United States Internal Revenue Service to the effect that such Cedara Plans are qualified and exempt from United States Federal income taxes under sections 401(a) and 501(a), respectively, of the Code, and no such determination letter has been revoked nor, to the knowledge of Cedara, has revocation been threatened, nor has any such Cedara Plan been amended since the date of its most recent determination letter or application therefor in any respect

that would adversely affect its qualification or materially increase its costs and, to the knowledge of Cedara, nothing has occurred since the date of such letter that could reasonably be expected to affect the qualified status of such plan.

(x) Except as set forth in Section 3.1(l) of the Cedara Disclosure Letter, no amount that could be received (whether in cash or property or the vesting of property) as a result of the transactions contemplated by this Agreement or the Arrangement by any employee, officer or director of Cedara or any of its affiliates who is a “disqualified individual” (as such term is defined in proposed United States Treasury Regulation Section 1.280G-1) under any employment, severance or termination agreement, other compensation arrangement or Cedara Plan currently in effect will fail to be deductible for United States federal income tax purposes by virtue of Section 280G of the Code.

(xi) Except as set forth in Section 3.1(l) of the Cedara Disclosure Letter, none of Cedara Plans is a “multiemployer plan” within the meaning of section 4001(a)(3) of ERISA or any other applicable Laws, nor has Cedara or any Cedara Subsidiary been obligated to contribute to any such multiemployer plan at any time within the past five years.

(xii) Except as set forth in Section 3.1(l) of the Cedara Disclosure Letter, none of the Cedara Plans provides for payment of a benefit, the increase of a benefit amount, the payment of a contingent benefit or the acceleration of the payment or vesting of a benefit by reason of the execution of or the consummation of the transactions contemplated by this Agreement or the Arrangement.

As of December 31, 2004, there is no significant deficiency or material weaknesses in the design or operation of Merge’s internal control over financial reporting and, to the knowledge of Merge, the attestation report of Merge’s auditors for the fiscal year ended December 31, 2004 will not indicate a significant deficiency or

material weakness in the design or operation of Merge’s internal control over financial reporting.

(q) Pension and Employee Benefits.

There are no actions, suits, claims (other than routine claims for payment of benefits in the ordinary course), trials, demands, investigations, arbitrations or other proceedings which are pending or threatened in respect of any of the Merge Plans or their assets which individually or in the aggregate would have a Material Adverse Effect on Merge or a Merge Material Subsidiary. Further, there exists no state or facts which after notice or lapse of time or both could reasonably be expected to give rise to any such action, suit, claim, trial, demand, investigation, arbitration or other proceeding.

(iii) Merge has made available to Cedara true, correct and complete copies of all of the Merge Plans as amended (or, in the case of any unwritten Merge Plan, a description thereof) together with all related documentation including, without limitation, funding agreements, actuarial reports, funding and financial information returns and statements and material correspondence with regulatory authorities with respect to each Merge Plan, and current plan summaries, booklets and personnel manuals.

To the knowledge of Merge, no fact or circumstance exists that could adversely affect the existing tax status of a Merge Plan.

(v) All obligations of Merge or a Merge Subsidiary regarding Merge Plans have been satisfied in all material respects. All contributions or premiums required to be made by Merge and/or a Merge Material Subsidiary, as the case may be, under the terms of each Merge Plan or by applicable Laws have been made in a timely fashion in accordance with applicable Laws and the terms of the Merge Plans.

(vi) Other than as set forth in Section 3.2(q) of the Merge Disclosure Letter or Publicly Disclosed by Merge, each Merge Plan is fully insured or fully funded and in good standing with such regulatory authorities as may be applicable pursuant to the actuarial assumptions in and, as of the date hereof, no notice of under-funding, non-compliance, failure to be in good standing or otherwise has been received by Merge or its Subsidiaries from any such regulatory authority. All liabilities of Merge and the Merge Material Subsidiaries (whether accrued, absolute, contingent or otherwise) related to the Merge Plans have been fully and accurately disclosed in accordance with GAAP in Merge’s financial statements.

(vii) There have been no improper withdrawals, applications or transfers of assets from any Merge Plan or the trusts or other funding media relating thereto that remain outstanding and unremedied, and neither Merge, nor any Merge Subsidiary, nor any of their respective agents has been in breach of any fiduciary obligation with respect to the administration of Merge Plans or the trusts or other funding media relating thereto.

(viii) No insurance policy or any other contract or agreement affecting any Merge Plan requires or permits a retroactive increase in premiums or payments due thereunder.

(ix) All Merge Plans intended to be tax-qualified in the United States have been the subject of determination letters from the United States Internal Revenue Service to the effect that such Merge Plans are qualified and exempt from United States Federal income taxes under sections 401(a) and 501(a), respectively, of the Code, and no such determination letter has

been revoked nor, to the knowledge of Merge, has revocation been threatened, nor has any such Merge Plan been amended since the date of its most recent determination letter or application therefor in any respect that would adversely affect its qualification or materially increase its costs and, to the knowledge of Merge, nothing has occurred since the date of such letter that could reasonably be expected to affect the qualified status of such plan.

(x) Except as set forth in Section 3.2(q) of the Merge Disclosure Letter, no amount that could be received (whether in cash or property or the vesting of property) as a result of the transactions contemplated by this Agreement or the Arrangement by any employee, officer or director of Merge or any of its affiliates who is a “disqualified individual” (as such term is defined in proposed United States Treasury Regulation Section 1.280G-1) under any employment, severance or termination agreement, other compensation arrangement or Merge Plan currently in effect will fail to be deductible for United States federal income tax purposes by virtue of Section 280G of the Code.

(xi) Except as set forth in Section 3.2(q) of the Merge Disclosure Letter, none of Merge Plans is a “multiemployer plan” within the meaning of section 4001(a)(3) of ERISA or any other applicable Laws, nor has Merge or any Merge Subsidiary been obligated to contribute to any such multiemployer plan at any time within the past five years.

(xii) Except as set forth in Section 3.2(q) of the Merge Disclosure Letter, none of the Merge Plans provides for payment of a benefit, the increase of a benefit amount, the payment of a contingent benefit or the acceleration of the payment or vesting of a benefit by reason of the execution of or the consummation of the transactions contemplated by this Agreement or the Arrangement.

Neither Merge nor any Merge Material Subsidiary is aware of any Health Laws to which Merge or such Merge Material Subsidiary is subject which requires or may require any work, repairs, construction, change in business practices or operations, or expenditures, including capital expenditures for facility upgrades. Neither Merge nor any Merge Material Subsidiary is aware of any demand, notice

or inspection report with respect to the breach of or liability under any Health Laws applicable to Merge or any Subsidiary.

Except as set forth in Section 3.2(s) of the Merge Disclosure Letter or Publicly Disclosed by Merge, there is no agreement, judgment, injunction, order or decree binding upon Merge or any Merge Subsidiary that has or could reasonably be expected to have the effect of prohibiting, restricting or materially impairing any business practice of Merge or any Merge Material Subsidiary, any acquisition of property by Merge or any Merge Material Subsidiary or the conduct of business by Merge or any Merge Material Subsidiary as currently conducted other than such agreements, judgments, injunctions, orders or decrees which would not, individually or in the aggregate, have a Material Adverse Effect on Merge.

Such notice shall include a description of the material terms and conditions of any proposal, the identity of the Person making such proposal, inquiry or contact and provide such other details of the proposal, inquiry or contact as Merge may reasonably request. Cedara shall (i) keep Merge fully informed of the status including any change to the material terms of any such Cedara Acquisition Proposal or inquiry and (ii) provide to Merge as soon as practicable after receipt or delivery thereof with copies of all correspondence and other written material sent or provided to Cedara or any Cedara Material Subsidiary from any Person in connection with any Cedara Acquisition Proposal or sent or provided by Cedara to any Person in connection with any Cedara Acquisition Proposal.

(iii) If Cedara receives a request for material non-public information from a Person who has made an unsolicited bona fide written Cedara Acquisition Proposal and Cedara is permitted, as contemplated under the second sentence of Section 4.5(a)(i), to negotiate the terms of such Cedara Acquisition Proposal, then, and only in such case, the Board of Directors of Cedara may, subject to the execution by such Person of a confidentiality agreement containing confidentiality and standstill provisions substantially similar to those contained in the Confidentiality Agreement, provide such Person with access to information regarding Cedara; provided, however, that the Person making the Cedara Acquisition Proposal shall not be precluded under such confidentiality agreement from making the Cedara Acquisition Proposal (but not any material amendment thereto) and provided further that Cedara sends a copy of any such confidentiality agreement to Merge promptly upon its execution and Merge is provided with a list of or copies of the information provided to such Person and immediately provided with access to similar information to which such person was provided.

(iv) Cedara shall ensure that its officers, directors and employees and its Subsidiaries and their officers, directors and employees and any financial advisors or other advisors or representatives retained by it are aware of the provisions of this section 4.5(a), and it shall be responsible for any breach of this section 4.5(a) by its officers, directors, employees, financial advisors or other advisors or representatives.

(b) Merge Covenants.

(i) Subject to section 4.6(b), Merge shall not, directly or indirectly, through any officer, director, employee, representative or agent of Merge or any of its Subsidiaries, (i) solicit, initiate or encourage (including by way of furnishing information or entering into any form of agreement, arrangement or understanding) the initiation of any inquiries or proposals regarding a Merge Acquisition Proposal, (ii) participate in any discussions or negotiations regarding any Merge Acquisition Proposal, (iii) withdraw or modify in a manner adverse to Cedara the approval of the Board of Directors of Merge of the transactions contemplated hereby, (iv) approve or recommend any Merge Acquisition Proposal or (v) enter into any agreement, arrangement or understanding related to any Merge Acquisition Proposal. Notwithstanding the preceding part of this section 4.5(b)(i) and any other provision of this Agreement, nothing shall prevent the Board of Directors of Merge prior to the issuance of the Final Order from considering, participating in any discussions or negotiations, or entering into a confidentiality agreement and providing information pursuant to section 4.5(b)(iii), regarding an unsolicited bona fide written Merge Acquisition Proposal that did not otherwise result from a breach of this section 4.5(b) and that the Board of Directors of Merge determines in good faith, after consultation with financial advisors and outside counsel, is reasonably likely to result in a Merge Superior Proposal; provided, however, that prior to taking such action, the Board of Directors of Merge must receive advice of outside counsel that the taking of such action by the Board of Directors is consistent with the proper discharge of its fiduciary duties. Merge shall not consider, negotiate, accept, approve or recommend a Merge Acquisition Proposal after the date of the issuance of the Final Order. Merge shall, and shall cause the officers, directors, employees, representatives and agents of Merge and its Subsidiaries to, cease immediately all discussions and negotiations regarding any proposal that constitutes, or may reasonably be expected to lead to, a Merge Acquisition Proposal.

(ii) Merge shall promptly notify Cedara, at first orally and then in writing, of any Merge Acquisition Proposal and any inquiry that could lead to a Merge Acquisition Proposal, or any amendments to the foregoing, or any request for non-public information relating to Merge or any Merge Material Subsidiary in connection with a Merge Acquisition Proposal or

for access to the properties, books or records of Merge or any Merge Material Subsidiary by any Person that informs Merge or such Merge Material Subsidiary that it is considering making, or has made, a Merge Acquisition Proposal. Such notice shall include a description of the material terms and conditions of any proposal, the identity of the Person making such proposal, inquiry or contact and provide such other details of the proposal, inquiry or contact as Cedara may reasonably request. Merge shall (i) keep Cedara fully informed of the status including any change to the material terms of any such Merge Acquisition Proposal or inquiry and (ii) provide to Cedara as soon as practicable after receipt or delivery thereof with copies of all correspondence and other written material sent or provided to Merge or any Merge Material Subsidiary from any Person in connection with any Merge Acquisition Proposal or sent or provided by Merge to any Person in connection with any Merge Acquisition Proposal.

(iii) If Merge receives a request for material non-public information from a Person who has made an unsolicited bona fide written Merge Acquisition Proposal and Merge is permitted, as contemplated under the second sentence of Section 4.5(b)(i), to negotiate the terms of such Merge Acquisition Proposal, then, and only in such case, the Board of Directors of Merge may, subject to the execution by such Person of a confidentiality agreement containing confidentiality and standstill provisions substantially similar to those contained in the Confidentiality Agreement, provide such Person with access to information regarding Merge; provided, however, that the Person making the Merge Acquisition Proposal shall not be precluded under such confidentiality agreement from making the Merge Acquisition Proposal (but not any material amendment thereto) and provided further that Merge sends a copy of any such confidentiality agreement to Cedara promptly upon its execution and Cedara is provided with a list of or copies of the information provided to such Person and immediately provided with access to similar information to which such person was provided.

(iv) Merge shall ensure that its officers and directors and its Subsidiaries and their officers and directors and any financial advisors or other advisors or representatives retained by it are aware of the provisions of this section 4.5(b), and it shall be responsible for any breach of this section 4.5(b) by its officers, directors, employees, financial advisors or other advisors or representatives.

4.6 Notice of Superior Proposal Determination

(a) Cedara Covenants.

(i) Notwithstanding section 4.5(a), Cedara may accept, approve, recommend or enter into any agreement, understanding or arrangement in respect of a

Cedara Superior Proposal if, and only if, (i) it has provided Merge with a copy of the Cedara Superior Proposal document, (ii) five Business Days shall have elapsed from the later of the date Merge received written notice advising Merge that Cedara’s Board of Directors has resolved, subject only to compliance with this section 4.6(a) and termination of this Agreement, to accept, approve, recommend or enter into an agreement in respect of such Cedara Superior Proposal, specifying the terms and conditions of such Cedara Superior Proposal and identifying the Person making such Cedara Superior Proposal, and the date Merge received a copy of such Cedara Superior Proposal and (iii) it has previously or concurrently will have (A) paid to Merge the break fee, if any, payable under section 6.4 and (B) terminated this Agreement pursuant to section 6.3. Any information provided by Cedara to Merge pursuant to this section 4.6(a) or pursuant to section 4.5(a) shall constitute “Information” under section 4.7(b).

(ii) During such five Business Day period, Cedara agrees that Merge shall have the right, but not the obligation, to offer to amend the terms of this Agreement. The Board of Directors of Cedara will review any offer by Merge to amend the terms of this Agreement in good faith in order to determine, in its discretion in the exercise of its fiduciary duties, whether Merge’s offer upon acceptance by Cedara would result in such Cedara Superior Proposal ceasing to be a Cedara Superior Proposal. If the Board of Directors of Cedara so determines, it will enter into an amended agreement with Merge reflecting Merge’s amended proposal. If the Board of Directors of Cedara continues to believe, in good faith and after consultation with financial advisors and outside counsel, that such Cedara Superior Proposal remains a Cedara Superior Proposal and therefore rejects Merge’s amended proposal, Cedara may terminate this Agreement pursuant to section 6.3(c)(iv); provided, however, that Cedara must concurrently pay to Merge the break fee payable, if any, to Merge under section 6.4 and must concurrently with termination enter into a definitive agreement with respect to such Cedara Acquisition Proposal. Cedara acknowledges and agrees that payment of the break fee, if any, payable under section 6.4 is a condition to valid termination of this Agreement under section 6.3(c)(iv) and this section 4.6(a). Cedara also acknowledges and agrees that each successive modification of any Cedara Acquisition Proposal shall constitute a new Cedara Acquisition Proposal for purposes of this section 4.6(a) to initiate an additional five Business Day notice period.

(b) Merge Covenants.

(i) Notwithstanding section 4.5(b), Merge may accept, approve, recommend or enter into any agreement, understanding or arrangement in respect of a Merge Superior Proposal if, and only if, (i) it has provided Cedara with a

copy of the Merge Superior Proposal document, (ii) five Business Days shall have elapsed from the later of the date Cedara received written notice advising Cedara that Merge’s Board of Directors has resolved, subject only to compliance with this section 4.6(b) and termination of this Agreement, to accept, approve, recommend or enter into an agreement in respect of such Merge Superior Proposal, specifying the terms and conditions of such Merge Superior Proposal and identifying the Person making such Merge Superior Proposal, and the date Cedara received a copy of such Merge Superior Proposal and (iii) it has previously or concurrently will have (A) paid to Cedara the break fee, if any, payable under section 6.4 and (B) terminated this Agreement pursuant to section 6.3. Any information provided by Merge to Cedara pursuant to this section 4.6(b) or pursuant to section 4.5(b) shall constitute “Information” under section 4.7(b).

(ii) During such five Business Day period, Merge agrees that Cedara shall have the right, but not the obligation, to offer to amend the terms of this Agreement. The Board of Directors of Merge will review any offer by Cedara to amend the terms of this Agreement in good faith in order to determine, in its discretion in the exercise of its fiduciary duties, whether Cedara’s offer upon acceptance by Merge would result in such Merge Superior Proposal ceasing to be a Merge Superior Proposal. If the Board of Directors of Merge so determines, it will enter into an amended agreement with Cedara reflecting Cedara’s amended proposal. If the Board of Directors of Merge continues to believe, in good faith and after consultation with financial advisors and outside counsel, that such Merge Superior Proposal remains a Merge Superior Proposal and therefore rejects Cedara’s amended proposal, Merge may terminate this Agreement pursuant to section 6.3(c)(vi); provided, however, that Merge must concurrently pay to Cedara the break fee payable, if any, to Cedara under section 6.4 and must concurrently with termination enter into a definitive agreement with respect to such Merge Acquisition Proposal. Merge acknowledges and agrees that payment of the break fee, if any, payable under section 6.4 is a condition to valid termination of this Agreement under section 6.3(c)(vi) and this section 4.6(b). Merge also acknowledges and agrees that each successive modification of any Merge Acquisition Proposal shall constitute a new Merge Acquisition Proposal for purposes of this section 4.6(b) to initiate an additional five Business Day notice period.

4.7 Access to Information

(a) Subject to sections 4.7(b) and (c) and applicable Laws, upon reasonable notice, Cedara shall (and shall cause each of its Subsidiaries to) afford Merge’s officers, employees, counsel, accountants and other authorized representatives and advisors (“Representatives”) access, during normal business hours from the date

hereof and until the earlier of the Effective Date or the termination of this Agreement, to its properties, books, contracts and records as well as to its management personnel, and, during such period, Cedara shall (and shall cause each of its Subsidiaries to) furnish promptly to Merge all information concerning Cedara’s business, properties and personnel as Merge may reasonably request. Subject to sections 4.7(b) and (c) and applicable laws, upon reasonable notice, Merge shall afford Cedara’s Representatives access, during normal business hours from the date hereof and until the earlier of the Effective Date or the termination of this Agreement, to its properties, books, contracts and records as well as to its management personnel, and, during such period, Merge shall (and shall cause each of its Subsidiaries to) furnish promptly to Cedara all information concerning Merge’s business, properties and personnel as Cedara may reasonably request. Nothing in the foregoing shall require Merge or Cedara to disclose to the other information subject to a written confidentiality agreement with third parties or customer-specific or competitively sensitive information relating to areas or projects where Merge and Cedara are in direct competition.

(b) In accordance with the Confidentiality Agreement, each of Merge and Cedara acknowledges that certain information provided to it under section 4.7(a) above will be non-public and/or proprietary in nature (the “Information”). Except as permitted below, each of Merge and Cedara will keep Information confidential and will not, without the prior written consent of the other, disclose it, in any manner whatsoever, in whole or in part, to any other Person, and will not use it for any purpose other than to evaluate the transactions contemplated by this Agreement. Each of Merge and Cedara will make all reasonable, necessary and appropriate efforts to safeguard the Information from disclosure to anyone other than as permitted hereby and to control the copies, extracts or reproductions made of the Information. The Information may be provided to the Representatives of each of Merge and Cedara who require access to the same to assist it in proceeding in good faith with the transactions contemplated by this Agreement and whose assistance is required for such purposes, provided that it has first informed such Representatives to whom Information is provided that the Representative has the same obligations, including as to confidentiality, restricted use and otherwise, that it has with respect to such Information. This provision shall not apply to such portions of the Information that: (i) are or become generally available to the public otherwise than as a result of disclosure by a party or its Representatives; or (ii) become available to a party on a non-confidential basis from a source other than, directly or indirectly, the other party or its Representatives, provided that such source is not to the knowledge of the first party, upon reasonable inquiry, prohibited from transmitting the Information by a contractual, legal or fiduciary obligation; (iii) were known to a party or were in its possession on a non-confidential basis prior to being disclosed to it by the other party or by someone on its behalf; or (iv) are required by applicable Laws or court order to be disclosed. The provisions of this section 4.7(b) shall survive the termination of this Agreement.

(c) The parties acknowledge that certain Information may be competitively sensitive and that disclosure thereof shall be limited to that which is reasonably necessary for the purpose of (i) preparing submissions or applications in order to obtain the Appropriate Regulatory Approvals, (ii) preparing the Circular, (iii) avoiding conflicts and (iv) integrating the operations of Merge and Cedara.

4.8 Closing Matters

Each of the Merge Parties and Cedara shall deliver, at the closing of the transactions contemplated hereby, such customary certificates, resolutions and other closing documents as may be required by the other parties hereto, acting reasonably.

4.9 Indemnification

(a) Merge agrees that all rights to indemnification or exculpation now existing in favour of the directors or officers of Cedara or any Subsidiary as provided in its articles of incorporation or by-laws in effect on the date hereof shall survive the Arrangement and shall continue in full force and effect for a period of not less than six years from the Effective Time and Merge hereby assumes, effective upon consummation of the Arrangement, all such liability with respect to any matters arising prior to the Effective Time.

(b) There shall be maintained in effect, for not less than six years from the Effective Time, coverage equivalent to that in effect under the current policies of the directors’ and officers’ liability insurance maintained by Cedara, which is no less advantageous, and with no gaps or lapses in coverages with respect to matters occurring prior to the Effective Time.

4.10 Section 3(a)(10) Exemption.

In the event that, due to an amendment to the 1933 Act, a change in the SEC’s interpretation of the 1933 Act or a decision of a court which provides that orders of Canadian courts such as the Final Order do not qualify under Section 3(a)(10) of the 1933 Act, the exemption from registration under Section 3(a)(10) of the 1933 Act is not available for any reason to exempt the issuance of the Merge Common Shares and Exchangeable Shares in accordance with the Arrangement from the registration requirements of the 1933 Act, then Merge shall take all necessary action to file a registration statement on Form S-4 (or on such other form that may be available to Merge) in order to register the Merge Common Shares and Exchangeable Shares, and shall use its reasonable best efforts to cause such registration statement to become effective at or prior to the Effective Time.

4.11 Board of Directors.

Merge agrees that, in connection with the annual meeting of the holders of Merge Common Shares to be held in 2005, the Board of Directors of Merge shall nominate for election at such meeting each of the Cedara Designees, and shall recommend in the proxy materials distributed to the holders of Merge Common Shares in connection with such meeting that such

holders vote in favor of each of the Cedara Designees. Notwithstanding the foregoing, if at any time, Merge’s Board of Directors receives advice of outside counsel that the taking of any action pursuant to this Section 4.11 would be inconsistent with the proper discharge of its fiduciary duties under applicable Law, Merge’s Board of Directors need not take such action.

4.12 Certain Employment Matters.

On the Effective Time and for a period not less than one year after the Effective Time, employees of Cedara and its Subsidiaries shall be provided employee benefits, plans and programs which are no less favorable in the aggregate than those available to such employees under the Cedara Plans on the date hereof. For purposes of eligibility to participate and vesting, waiting periods, pre-existing conditions and similar purposes (but not benefit accrual attributable to the period before the Effective Time) in all benefits provided to employees, the employees of Cedara and its Subsidiaries will be credited with their years of service with Cedara and its Subsidiaries and prior employers, to the extent such service is taken into account under current plans of Cedara and its Subsidiaries. In addition, the parties shall effect the matters with respect to Cedara employees and directors which are set forth in Schedule G attached hereto. Nothing in this Section 4.12 shall be construed as restricting the ability of Merge or its Subsidiaries to establish such types and levels of compensation and benefits or to modify or terminate such compensation or benefits as they determine to be appropriate from time to time.

6.5 Effect of Break Fee Payment

For greater certainty, the parties hereto agree that if a party pays to another party amounts required by section 6.4 as a result of the occurrence of any of the events referenced in section 6.4, the parties to this Agreement shall have no other remedy for any breach of this Agreement by the party making such payment.

6.6 Remedies

Subject to section 6.5, the parties hereto acknowledge and agree that an award of money damages would be inadequate for any breach of this Agreement by any party or its representatives and any such breach would cause the non-breaching party irreparable harm. Accordingly, the parties hereto agree that, in the event of any breach or threatened breach of this Agreement by one of the parties, the non-breaching party will also be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance. Such remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available at law or equity to each of the parties.
