(g) Other than in the ordinary course of business consistent with past practice, Peak will not, and will not permit any of its Subsidiaries to, make any loans, advances or

(i) Peak will use its commercially reasonable efforts to cause the current insurance (or re-insurance) policies maintained by Peak or any of its Subsidiaries, including directors’ and officers’ insurance, not to be cancelled or terminated and to prevent any of the coverage thereunder from lapsing, unless simultaneously with such termination, cancellation or lapse, replacement policies underwritten by insurance or re-insurance companies of nationally recognized standing having comparable deductions and providing coverage equal to or greater than the coverage under the cancelled, terminated or lapsed policies for substantially similar premiums are in full force and effect; provided that, subject to the provisions of Section 7.9, none of Peak or any of its Subsidiaries will obtain or renew any insurance (or re-insurance) policy for a term exceeding 12 months.

Section 5.2. Pre-Acquisition Transactions

(a) Subject to the provisions of Section 5.2(d), prior to the Effective Time, Peak agrees to (i) at Parent’s expense, cooperate with and provide reasonable assistance to Parent in connection with Parent’s planning for and implementation of any such reorganizations of the business, operations, assets or corporate structure of Peak and its Subsidiaries as Parent may request, acting reasonably (each a “Pre-Acquisition Transaction”), and (ii) at Parent’s expense, use commercially reasonable efforts to implement in advance of the Effective Time any Pre-Acquisition Transaction as reasonably requested by Parent. At Parent’s option, such Pre-Acquisition Transactions may include, without limitation, (i) formation of new Peak Subsidiaries, (ii) merger, amalgamation or consolidation of existing Peak Subsidiaries, (iii) transfer of securities in, or assets held by, existing Peak Subsidiaries either by sale, dividend or contribution, and (iv) filing of any elections required or permitted under applicable Tax Laws relating to such transactions.

(b) Subject to the provisions of Section 5.2(d), to the extent that a Pre-Acquisition Transaction requires approval of the Peak Shareholders under the ABCA, Peak shall at Parent’s expense, (i) seek approval of the Peak Shareholders for such Pre-Acquisition Transaction at the Peak Meeting, (ii) include in the Peak Circular a form of special resolution of the Peak Shareholders (the “Transaction Resolution”) approving such Pre-Acquisition Transaction in form and substance acceptable to Parent, acting reasonably, either included within the Arrangement Resolution or separate from the Arrangement Resolution if so requested by Parent, and (iii) include in the Peak Circular the unanimous recommendation of the Board that the Peak Shareholders vote in favour of the Transaction Resolution, provided

that Parent and Purchaser agree to amend the provisions of this Agreement requiring Peak to take certain action by specified times, including such provisions contained in Sections 2.1 and 2.3, to the extent necessary to facilitate the foregoing. Subject to the provisions of this Section 5.2, the provisions in Article II regarding Peak’s obligations respecting the approval of the Arrangement Resolution shall, save and except for the last sentence of Section 2.5, apply mutatis mutandis to the approval of the Transaction Resolution.

(c) Subject to the provisions of Sections 5.2(a), 5.2(b) and 5.2(d), the Parties will work cooperatively and use commercially reasonable efforts to prepare prior to the Effective Time all documentation necessary and do such other acts and things as are necessary to give effect to any Pre-Acquisition Transactions. Subject to the provisions of Sections 5.2(a), 5.2(b) and 5.2(d), the Parties shall give effect to any Pre-Acquisition Transactions immediately before the Effective Time and shall seek to have them become effective immediately before the Effective Time (but after Parent shall have confirmed that all conditions in Sections 6.1 and 6.2 have been satisfied or waived by Parent and Peak shall have confirmed that all conditions in Sections 6.1 and 6.3 have been satisfied or waived by Peak). In no event shall completion of any Pre-Acquisition Transaction be a condition to completion of the Arrangement.

(d) Notwithstanding the foregoing, Peak shall not be required to take any action with respect to a Pre-Acquisition Transaction unless it determines to its satisfaction, acting reasonably, that: (A) such implementation will not delay or prevent consummation of the Arrangement (including by giving rise to litigation by third parties); (B) such implementation will not have an adverse impact on the Peak Shareholders; (C) such implementation will not have an adverse impact on Peak should the Arrangement not be consummated for any reason; (D) the Arrangement will be consummated and the Effective Time will occur immediately following the completion of such Pre-Acquisition Transaction; (E) any proposed Pre-Acquisition Transaction shall not require Peak to contravene any Laws, its organizational documents or any Contract material to Peak and its Subsidiaries taken as a whole; and (F) Peak and its Subsidiaries and their respective officers, directors, employees, agents, advisors and representatives shall have received an indemnity, in form and substance satisfactory to Peak, acting reasonably, from Parent from and against any and all liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments and penalties suffered or incurred by any of them in connection with or as a result of any Pre-Acquisition Transaction. The determination as to whether the conditions set out in (A) to (F) have or will be satisfied shall be solely that of Peak, acting reasonably.

(e) Parent agrees that the planning for and implementation of any Pre-Acquisition Transaction at Parent’s request in advance of the Effective Time will not be considered a breach of any covenant under this Agreement and will not be considered in determining whether a representation or warranty of Peak under this Agreement has been breached. For greater certainty, Peak shall not be liable for any failure to properly implement any Pre-Acquisition Transaction or for the failure of Parent or Purchaser to benefit from any anticipated tax efficiency.

Section 5.3. Covenants of Peak Regarding the Arrangement

Peak will perform, and will cause its Subsidiaries to perform, all obligations required or desirable to be performed by Peak or any of its Subsidiaries under this Agreement, co-operate with Parent and Purchaser in connection therewith, and do all such other acts and things as may be necessary or desirable in order to consummate and make effective, as soon as reasonably practicable, the transactions contemplated by this Agreement and, without limiting the generality of the foregoing, Peak will and, where appropriate, will cause its Subsidiaries to:

(a) except as specifically permitted by Section 7.2, use all commercially reasonable efforts to obtain the Required Vote;

(b) unless this Agreement has been terminated in accordance with Section 8.2, submit the Arrangement to the Peak Shareholders at the Peak Meeting even if the Board has withdrawn, amended, modified or qualified its recommendation of the Arrangement;

(d) use its commercially reasonable efforts to effect all necessary registrations, filings and submissions of information required by Governmental Entities from Peak or any of its Subsidiaries relating to the Arrangement;

(e) apply for and use all commercially reasonable efforts to obtain all Regulatory Approvals relating to Peak or any of its Subsidiaries which are typically applied for by a Person being acquired and, in doing so, keep Parent reasonably informed as to the status of the proceedings related to obtaining the Regulatory Approvals, including providing Parent with copies of all related applications and notifications (other than confidential information contained in such applications and notifications), in draft form, in order for Parent to provide its comments thereon; provided, however, that nothing in this Agreement shall require Peak or its Affiliates to divest or hold separate or otherwise take or commit to take any action with respect to any asset, property or agreement of Peak or any of its Subsidiaries in order to obtain any such Regulatory Approval;

(f) use its commercially reasonable efforts to defend all lawsuits or other legal, regulatory or other proceedings against Peak or any of its Subsidiaries challenging or affecting this Agreement or the consummation of the transactions contemplated hereby;

(g) subject to applicable Laws relating to the exchange of information, and subject to the terms of the Confidentiality Agreement, upon request by Parent, furnish Parent with all information concerning (i) itself and its Subsidiaries (including information concerning their respective businesses, operations, markets, customers, suppliers and others they have business relations with) and (ii) historical and pro forma financial statements, in connection with Parent’s financing (including syndication efforts) for the transactions contemplated by this Agreement, provided that in no event shall the Confidential Information (as defined in the Confidentiality Agreement) of Peak be disclosed (except as provided in the Confidentiality Agreement) to any Person without the prior written consent of Peak. Notwithstanding the foregoing, Parent agrees that Peak will not be liable for any failure of Parent or Purchaser to obtain financing for the transactions contemplated by this Agreement; and

(h) abide by the terms of the Confidentiality Agreement.

Section 5.4. Covenants of Parent

Parent will perform, and will cause Purchaser to perform, all obligations required or desirable to be performed by it under this Agreement, co-operate with Peak in connection therewith, and do all such other acts and things as may be necessary or desirable in order to consummate and make effective, as soon as reasonably practicable, the transactions contemplated by this Agreement and, without limiting the generality of the foregoing, Parent will, and where appropriate will cause Purchaser to:

(a) apply for and use all commercially reasonable efforts to obtain all Regulatory Approvals relating to it and relating to Peak or any of Peak’s Subsidiaries which are typically applied for by an acquiror (including those referenced in Schedule C) and, in doing so, keep Peak reasonably informed as to the status of the proceedings related to obtaining the Regulatory Approvals, including providing Peak with copies of all related applications and notifications in draft form (other than confidential information contained in such applications and notifications), in order for Peak to provide its reasonable comments thereon; provided, however, that nothing in this Agreement shall require Parent or its Affiliates to divest or hold separate or otherwise take or commit to take any action with respect to any asset, property or agreement of Parent or any of its Subsidiaries in order to obtain any such Regulatory Approval;

(b) use its commercially reasonable efforts to effect all necessary registrations, filings and submissions of information required by Governmental Entities from Purchaser or any of its Subsidiaries relating to the Arrangement;

(c) use its commercially reasonable efforts to ensure that Purchaser will continue to have available the required funds to consummate the Arrangement at the Effective Time;

(d) use its commercially reasonable efforts to defend all lawsuits or other legal, regulatory or other proceedings against Parent or Purchaser challenging or affecting this Agreement or the consummation of the transactions contemplated hereby;

(e) abide by the terms of the Confidentiality Agreement; and

(f) on and after the Effective Time, provide for the continuing employees of Peak and its Subsidiaries credit under the relevant Parent Plans for the period of their employment by Predecessor, Peak or their Subsidiaries and permit them to participate in Parent’s employee stock purchase plan if they wish to do so. Peak’s continuing management employees will also be entitled to participate in a cash bonus arrangement similar to Parent’s management incentive plan (“MIP”) on terms similar to comparable management employees of Parent and its Subsidiaries, provided that separate EBITDA goals for Peak will be established based on the Peak’s performance during the stub period beginning on the Effective Time and ending on December 31, 2011.

Section 5.5. Mutual Covenants

Each of the Parties covenants and agrees that, except as contemplated in this Agreement, during the period from the date of this Agreement until the earlier of the Effective Time and the time that this Agreement is terminated in accordance with its terms:

(a) it will, and will cause its Subsidiaries to, use commercially reasonable efforts to satisfy (or cause the satisfaction of) the conditions precedent to its obligations hereunder as set forth in Article VI to the extent the same is within its control and to take, or cause to be taken, all other action and to do, or cause to be done, all other things necessary, proper or advisable under all applicable Laws to consummate the Arrangement, including using its commercially reasonable efforts to: (i) oppose, lift or rescind any injunction or restraining order against it or other order or action against it seeking to stop, or otherwise adversely affecting its ability to make and complete, the Arrangement; and (ii) co-operate with the other Parties in connection with the performance by it and its Subsidiaries of their obligations hereunder and

(b) it will not (i) take any action, (ii) refrain from taking any commercially reasonable action, or (iii) permit any action to be taken or any commercially reasonable action to not be taken, which is inconsistent with this Agreement or which would reasonably be expected to significantly impede the consummation of the Arrangement or to prevent or materially delay the consummation of the transactions contemplated hereby.

ARTICLE VII.
ADDITIONAL AGREEMENTS

Section 7.1. Notice Provisions

(a) Each of Peak and Parent will give prompt notice to the other of the occurrence, or failure to occur, at any time from the date hereof until the earlier to occur of the termination of this Agreement and the Effective Time of any event or state of facts which occurrence or failure would, or would be likely to:

(i) cause any of the representations or warranties of such Party contained herein to be untrue or inaccurate in any material respect on the date hereof or at the Effective Time; or

(ii) result in the failure to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by such Party hereunder prior to the Effective Time.

(b) Each of Peak and Parent will promptly notify the other Party of (i) any communication from any Person alleging that the consent of such Person (or another Person) is or may be required in connection with the transactions contemplated by this Agreement (and the response thereto from such Party, its Subsidiaries or its representatives), (ii) any material communication from any Governmental Entity in connection with the transactions contemplated by this Agreement (and the response thereto from such Party, its Subsidiaries or its representatives), and (iii) any material Legal Actions threatened or commenced against or otherwise affecting such Party or any of its Subsidiaries that are related to the transactions contemplated by this Agreement.

Section 7.2. Non-Solicitation

(a) Except as expressly provided in this Article VII, Peak will not, directly or indirectly, through any officer, director, employee, representative (including any financial or other advisor) or agent of Peak or any of its Subsidiaries, take any action of any kind which might, directly or indirectly, interfere with the successful completion of the Arrangement, including any action to (i) solicit, assist, initiate, knowingly facilitate or encourage (including by way of furnishing or providing access to any information or permitting any visit to any facilities or properties of Peak or any of its Subsidiaries, or entering into any form of Contract) the initiation of any inquiries, proposals or offers regarding an Acquisition Proposal, (ii) participate in any discussions or negotiations with any Person (other than Parent or Purchaser and their Affiliates and advisors) regarding an actual or potential Acquisition Proposal, (iii)

accept, approve, endorse or recommend or remain neutral with respect to, or propose publicly to approve, endorse or recommend or remain neutral with respect to, any Acquisition Proposal, or (iv) accept or enter into, or publicly propose to accept or enter into, any Contract in respect of an Acquisition Proposal (other than a confidentiality agreement permitted by Section 7.2(d)).

(b) Peak will, and will cause the officers, directors, employees, representatives and agents of Peak and its Subsidiaries to, immediately terminate any existing solicitations, discussions or negotiations with any Person (other than Parent or Purchaser and their Affiliates and advisors) that has made, indicated any interest to make or may reasonably be expected to make, an Acquisition Proposal and will cease to provide to any such Person any information or access to any information, concerning Peak or any of its Subsidiaries. Peak agrees not to release any third party from, waive any provision of, forebear in the enforcement of, or terminate any confidentiality agreement or standstill agreement to which it is a party. Peak will promptly request the return or destruction of all information provided to any third party which, at any time since January 1, 2009, has entered into a confidentiality agreement with Predecessor or Peak relating to a potential Acquisition Proposal to the extent that such information has not previously been returned or destroyed, and will use all commercially reasonable efforts to ensure that such requests are honoured in accordance with the terms of such agreement. For greater certainty, Peak will not permit any Person other than Parent, Purchaser and their lenders and advisors to access any virtual data room established except as permitted under Section 7.2(d)(D).

(c) Peak will promptly (and in any event within 24 hours of receipt by Peak) notify Parent, at first orally and thereafter in writing, of any proposal, inquiry, offer (or any amendment thereto) or request relating to or constituting an Acquisition Proposal, or that could be reasonably expected to lead to an Acquisition Proposal, in each case received after the date hereof, of which any of its directors, officers, representatives or agents are or become aware, or any amendments to the foregoing, any request for discussions or negotiations, any request for representation on the Board, or any request for non-public information relating to Peak or any of its Subsidiaries in connection with an Acquisition Proposal or for access to the properties, books or records of Peak or any of its Subsidiaries by any Person that informs Peak or such Subsidiary that it is considering making, or has made, an Acquisition Proposal or any amendment thereto; and Peak will promptly provide to Parent a description of the material terms and conditions of any such Acquisition Proposal or, inquiry, offer or request, together with a copy of all documentation relating to any such Acquisition Proposal or inquiry, offer or request, the identity of the Person making such proposal, inquiry, offer or request, and any other details of the Acquisition Proposal, contract, documents or negotiations as Parent may reasonably request. Peak will keep Parent informed of any change to the material terms of any such Acquisition Proposal or proposal, inquiry, offer or request.

(d) Notwithstanding the foregoing provisions of this Section 7.2 or any other provision of this Agreement, the Board will be permitted to (i) postpone or adjourn the Peak Meeting; (ii) withdraw, amend, modify or qualify (or propose to withdraw, amend, modify or qualify) in a manner adverse to Parent or Purchaser the approval or recommendation of this Agreement or the Arrangement; and (iii) participate in any discussions with, or furnish

information to any Person in response to an Acquisition Proposal by such Person, if and only to the extent that:

(A) Peak has received an unsolicited bona fide written Acquisition Proposal from such Person and the Board has determined that such Acquisition Proposal (which Acquisition Proposal, for greater clarity, may contain a due diligence condition) could reasonably be expected to lead to a Superior Proposal;

(B) Peak will have complied with all other requirements of this Section 7.2 (other than Section 7.2(g));

(C) the Board, after consultation with and based upon the advice of its outside legal counsel, determines in good faith that the failure to take such action would be inconsistent with its fiduciary duties under all applicable Laws;

(D) in the case of clause (iii) of this Section 7.2(d), prior to providing any information or data to such Person in connection with such Acquisition Proposal, the Board receives from such Person an executed confidentiality agreement having substantially the same terms as the Confidentiality Agreement (except that all “no-shop” provisions may be omitted) and, taken as a whole, being no less favourable to Peak than the Confidentiality Agreement (provided that such confidentiality agreement, if not existing on the date hereof, may not preclude Peak from complying with the provisions of this Agreement and may not include any provision calling for an exclusive right to negotiate with Peak and may not prohibit Peak from providing information to Parent regarding the Acquisition Proposal), and Peak sends a copy of any such confidentiality agreement to Parent promptly upon its execution and Parent is immediately provided with a list of, or in the case of information that was not previously made available to Parent, copies of or access to, any information provided to such Person; and

(E) in the case of clause (iii) of this Section 7.2(d), prior to providing any information or data to any such Person or entering into discussions with any such Person who has made an Acquisition Proposal, Peak has complied with Section 7.2(c).

(e) Nothing contained in this Section 7.2 will prohibit the Board from making any disclosure to Peak Shareholders prior to the Effective Time if, in the good faith judgment of the Board, after consultation with outside legal counsel, such disclosure is necessary for the Board to act in a manner consistent with its fiduciary duties or is otherwise required under applicable Law.

(f) Peak will, within five (5) Business Days, promptly publicly reaffirm its recommendation of this Agreement and the Arrangement after any Acquisition Proposal that is not a Superior Proposal is publicly announced or made.

(g) Nothing contained in this Section 7.2 will limit in any way the obligation of Peak to convene and hold the Peak Meeting in accordance with Section 2.2 of this Agreement unless this Agreement is terminated in accordance with Article VIII.

Section 7.3. Right to Match

(a) Subject to Section 7.3(b), Peak covenants that it will not accept, approve, recommend or enter into any agreement, understanding, arrangement or Contract in respect of a Superior Proposal (other than a confidentiality agreement permitted by Section 7.2(d)) unless:

(i) Peak has complied with its obligations under Section 7.2 and the other provisions of this Article VII; and

(ii) a period (the “Response Period”) of three Business Days will have elapsed from the date on which Parent received written notice from the Board that the Board determined, subject only to compliance with this Section 7.3, to accept, approve, recommend or enter into a binding agreement to proceed with the Superior Proposal. In the event that Peak provides Parent with the notice contemplated in this Section on a date that is less than three Business Days prior to the Peak Meeting, Peak will be entitled to adjourn the Peak Meeting to a date that is not more than three Business Days after the date of such notice.

(b) During the Response Period, Parent will have the right, but not the obligation, to offer to amend the terms of this Agreement. The Board will review any such proposal by Parent to amend the terms of this Agreement, including an increase in, or modification of, the consideration to be received by the Peak Shareholders, to determine whether the Acquisition Proposal to which Parent is responding would be a Superior Proposal when assessed against the Arrangement as it is proposed by Parent to be amended. If the Board determines that the Acquisition Proposal would no longer be a Superior Proposal if the Arrangement was so amended and Parent and Purchaser enter into an amendment to this Agreement incorporating the terms of the amended offer, the Board will promptly publicly reaffirm its recommendation of the Arrangement. If the Board determines in good faith after consultation with its financial advisors, that the Acquisition Proposal continues to be a Superior Proposal and, after consultation with and based upon the advice of its outside legal counsel, determines in good faith that the failure to accept such Superior Proposal would be inconsistent with its fiduciary duties under all applicable Laws, Peak may approve, recommend, accept or enter into an agreement, understanding or arrangement to proceed with the Superior Proposal.

(c) Each successive amendment to any Acquisition Proposal that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by the Peak Shareholders will constitute a new Acquisition Proposal for the purposes of this Section 7.3 and Parent will be afforded a new Response Period in respect of each such Acquisition Proposal.

(d) Peak shall use its commercially reasonable efforts to ensure that the directors and officers of Peak and each of its Subsidiaries and any investment bankers, counsel or other advisors, representatives or agents retained by Peak are aware of, and abide by, the provisions of Sections 7.2 and 7.3.

Section 7.4. Agreement as to Damages

(a) Notwithstanding any other provision relating to the payment of fees or expenses, in the event of termination of this Agreement and the Plan of Arrangement under the various circumstances set forth below, either Peak or Parent shall owe the other Party a termination fee and/or reimbursement of expenses, if any, as follows:

(i) if Parent terminates this Agreement pursuant to

(A) Section 8.2(c)(i) [Board fails to recommend, etc.], or

(B) Section 8.2(c)(ii) [breach by Peak],

Peak will pay to Parent a termination fee of $5.3 million (the “Peak Termination Fee”) within two Business Days of such termination, plus Parent’s Expense Reimbursement Costs not to exceed $2.0 million as provided in Section 7.4(c) below; provided, however, that if Parent terminates this Agreement pursuant to Section 8.2(c)(ii) based upon a failure of one or more of Peak’s representations and warranties contained in Section 3.1 to be true and correct as of the Closing Date and such failure was not the result of a willful breach of this Agreement by Peak, Peak will be obligated to pay Parent’s Expense Reimbursement but will not be obligated to pay the Peak Termination Fee;

(ii) if

(A) after the date hereof and prior to the termination of this Agreement, a bona fide Acquisition Proposal will have been made or proposed to Peak or otherwise publicly announced (which has not been withdrawn), or a Person has publicly announced an intention to do so (which has not been withdrawn),

(B) this Agreement is terminated by either Parent or Peak pursuant to Section 8.2(b)(ii) [Required Vote not obtained], and

Peak will pay to Parent, within two Business Days of the consummation of such Acquisition Proposal, Parent’s Expense Reimbursement Costs not to exceed $2.0 million as provided in Section 7.4(c) below; or

(iii) if Peak terminates this Agreement pursuant to Section 8.2(d)(i) [Board approves agreement for Superior Proposal], Peak will pay to Parent the Peak Termination Fee before or concurrently with such termination (and payment of the Peak Termination Fee will be a condition to the effectiveness of such termination), plus Parent’s Expense Reimbursement Costs not to exceed $2.0 million as provided in Section 7.4(c) below.

(b) If Peak terminates this Agreement pursuant to Section 8.2(d)(ii) [Parent’s breach], Parent will pay to Peak a termination fee of $3.0 million within two Business Days of

such termination, plus Peak’s Expense Reimbursement Costs not to exceed $1.5 million as provided under Section 7.4(c) below.

(c) Expense Reimbursement Costs shall be paid not later than two Business Days after delivery to the Party responsible for such payment of notice of demand for payment and documented itemization setting forth in reasonable detail all Expense Reimbursement Costs (which itemization may be supplemented and updated from time to time until the thirtieth day after delivery of the first notice of demand for payment), provided that no notice of demand for payment may be made more than 60 calendar days following the termination of this Agreement.

(d) The Parties acknowledge that the agreements contained in this Section 7.4 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, neither Parent nor Peak would have entered into this Agreement; accordingly, if Peak or Parent fails to timely pay any amount due pursuant to this Section 7.4 and, in order to obtain the payment, the Party who is owed such payment commences a suit which results in a judgment against the other Party for the payment set forth in this Section 7.4, the defaulting Party shall pay to the other Party its reasonable costs and expenses (including reasonable attorneys’ fees) in connection with such suit, together with interest on the amount due from each day for which payment is due until the date of the payment at the prime rate of the Bank of Canada in effect on the date such payment was required to be made.

Section 7.5. Fees and Expenses

Except as provided in Section 7.4, each Party will pay all fees, costs and expenses incurred by such Party in connection with this Agreement and the Arrangement. For such purposes, the filing fees paid to Governmental Entities in connection with applicable filings under the Competition Act and any applicable antitrust laws of other jurisdictions shall be shared equally by Parent and Peak.

Section 7.6. Liquidated Damages, Injunctive Relief and No Liability of Others

Parent and Peak acknowledge that all of the payment amounts set out in Section 7.4 are payments of liquidated damages which are a genuine pre-estimate of the damages Parent or Peak will suffer or incur as a result of the event giving rise to such payment and the resultant termination of this Agreement and are not penalties. Parent and Peak irrevocably waive any right to raise as a defense that any such liquidated damages are excessive or punitive. For greater certainty, the Parties agree that, subject to Section 7.4, payment of the amount determined pursuant to this Article in the manner provided in respect thereof is the sole monetary remedy of the Party receiving such payment. Nothing contained herein will preclude a Party from seeking injunctive relief in accordance with Section 9.3 to restrain any breach or threatened breach of the covenants or agreements set forth in this Agreement or the Confidentiality Agreement or otherwise to obtain specific performance of any of such acts, covenants or agreements, without the necessity of posting a bond or security in connection therewith. In the event that either Parent or Peak become liable to make a payment under Section 7.4, there will be no liability of any shareholder, director, officer, employee, advisor or representative of Parent or Peak or any Affiliate thereof, whether to the other Party or any other Person (including any shareholder,

director, officer, employee, advisor or representative thereof) in connection with any liability or other obligation of the Parent or Peak, and whether hereunder or otherwise in connection with the transactions contemplated hereby.

Section 7.7. Access to Information; Confidentiality

(a) From the date hereof until the earlier of the Effective Time and the termination of this Agreement, subject to compliance with applicable Law and the terms of any existing Contracts, Peak will, and will cause its Subsidiaries and their respective officers, directors, employees, independent auditors, accounting advisers and agents to, afford to Parent and to its officers, employees, agents, representatives and advisers such access as Parent may reasonably request at all reasonable times, including for the purpose of facilitating integration business planning, to their officers, employees, agents, properties, books, records and Contracts, and will furnish Parent with all data and information as Parent may reasonably request. Without limiting the foregoing, Parent and its representatives (including its financing sources) will, upon reasonable prior notice, have the right to conduct appraisal and environmental and engineering inspections of each of the Properties, and to contact any third party to a Material Contract to which Peak or any of its Subsidiaries is a party; provided, that no such inspections will be conducted in a manner which disrupts in any material respect the normal course of business of Peak at the applicable Property. Parent and Peak acknowledge and agree that information furnished pursuant to this Section 7.7(a) will be subject to the terms and conditions of the Confidentiality Agreement. All such access and all requests for information shall be coordinated through the President and Chief Executive Officer of Peak.

(b) No investigation conducted pursuant to Section 7.7(a) shall affect or be deemed to modify any representation or warranty made by Peak hereunder, and nothing in Section 7.7(a) shall require Peak to permit any inspection, or to disclose any information, that in the reasonable judgment of Peak would result in (i) a violation of any of its obligations with respect to confidentiality if Peak shall have used reasonable efforts to obtain the consent of any third party to such inspection or (ii) any violation of Laws relating to the sharing of information between competitors, it being understood that (A) Peak will provide extracts, or summaries, or aggregations or other information to the greatest extent practicable in a manner that does not result in any such violation or improper disclosure and (B) Peak will provide certain information in accordance with, and subject to, the confidentiality provisions of the Clean Team Agreement.

Section 7.8. Privacy Compliance

(a) For purposes of this Section 7.8:

(i) “Disclosed Personal Information” means any Personal Information disclosed to Purchaser or Parent by Peak or its advisors;

(ii) “Personal Information” means information about an identifiable individual, but does not include an individual’s name, position name or title, business telephone number, business address, business email or business fax number.

(b) Before the Effective Time, none of the Parties shall use the Disclosed Personal Information for any purposes other than those related to the performance of this Agreement and the completion of the Arrangement.

(c) Each of the Parties acknowledges and confirms that the disclosure of Personal Information is necessary for the purposes of determining if the Parties shall proceed with the Arrangement, and that the disclosure of Personal Information relates solely to the carrying on of Peak’s business or the completion of the Arrangement.

(e) Purchaser and Parent undertake, after the Effective Time, to utilize the Disclosed Personal Information only for those purposes for which the Disclosed Personal Information was initially collected by Purchaser and Parent.

(f) If the Effective Time does not occur, Purchaser and Parent shall forthwith cease all use of the Disclosed Personal Information in connection with this Agreement and will return to Peak or, at Peak’s request, destroy in a secure manner, the Disclosed Personal Information (and any copies thereof) and provide Peak with a certificate confirming that destruction.

Section 7.9. Insurance and Indemnification

(a) If the Arrangement shall become effective, Parent will, or will cause Peak and its Subsidiaries to, maintain in effect without any reduction in scope or coverage for six years from the Effective Time customary policies of directors’ and officers’ liability insurance providing protection equal to or better than the protection provided by the policies maintained by Peak and its Subsidiaries which are in effect immediately prior to the Effective Time and providing protection in respect of claims arising from facts or events which occurred on or prior to the Effective Time; provided, however, that Parent will not be required, in order to maintain such directors’ and officers’ liability insurance policy, to pay, or to cause Peak and its Subsidiaries to pay, an annual premium in excess of 250% of the cost of the existing policies; and provided further that, if equivalent coverage cannot be obtained or can only be obtained by paying an annual premium in excess of 250% of such amount, Parent will only be required to obtain, or to cause Peak and its Subsidiaries to obtain, as much coverage as can be obtained by paying an annual premium equal to 250% of such amount. Furthermore, prior to the Effective Time Peak may, in the alternative, purchase run off directors’ and officers’ liability insurance for a period of up to six years from the Effective Time provided that the premiums will not exceed 250% of the premiums currently charged to Peak for directors’ and officers’ liability insurance.

(b) Parent agrees that it will directly honour all rights to indemnification or exculpation now existing in favour of present and former officers and directors of Predecessor, Peak and their Subsidiaries which will survive the completion of the Arrangement.

(c) The provisions of this Section 7.8 are intended for the benefit of, and will be enforceable by, each insured or indemnified Person described in Section 7.8(a), his or her heirs and his or her legal representatives and, for such purpose, the Parties hereby confirm that, in negotiating and agreeing with the provisions of this Section 7.8, Peak is acting as agent and trustee on their behalf.

Section 7.10. Exchange De-Listing

Parent and Peak will use their commercially reasonable efforts to cause the Peak Common Shares to be de-listed from the TSX promptly following the Effective Time.

Section 7.11. Tax Matters

During the period from the date of this Agreement to the Effective Time, Peak and its Subsidiaries will:

(a) prepare and timely file all Returns (which shall be correct and complete in all respects) required to be filed by them on or before the Effective Time (“Post-Signing Returns”) in a manner consistent, in all material respects, with past practice, except as otherwise required by applicable Laws;

(b) pay, withhold, collect and remit in a timely fashion all amounts of Taxes required to be so paid, withheld, collected or remitted; and

(c) properly reserve (and reflect such reserve in their books and records and financial statements) for all Taxes payable by them for which no Post-Signing Return is due prior to the Effective Time in a manner consistent with past practice.

Section 7.12. Resignations

Subject to confirmation that insurance coverage is maintained as contemplated by Section 7.9, Peak will obtain and deliver to Parent at the Effective Time evidence reasonably satisfactory to Parent of the resignation effective as of the Effective Time of those directors of Peak designated by Parent to Peak in writing at least five calendar days prior to the Effective Time.

This Agreement will be governed, including as to validity, interpretation and effect, by the laws of the Province of Alberta and the laws of Canada applicable therein, and will be construed and treated in all respects as an Alberta contract. Each of the Parties hereby irrevocably attorns to the non-exclusive jurisdiction of the Courts of the Province of Alberta in respect of all matters arising under and in relation to this Agreement and the Arrangement.

Section 9.3. Injunctive Relief

The Parties agree that irreparable harm would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached for which money damages would not be an adequate remedy at law.

Section 9.4. Time of Essence

Time will be of the essence in this Agreement.

Section 9.5. Entire Agreement, Binding Effect and Assignment

(a) Provided it is acceptable to the Court without the imposition of commercially unreasonable conditions or any other conditions that would impede, prevent or materially delay the completion of the transactions contemplated hereby by the Outside Date, Parent and Purchaser may assign all or any part of their respective rights under this Agreement to, and their respective obligations under this Agreement may be assumed by, a Subsidiary or Affiliate of Parent or Purchaser, provided that if such assignment and/or assumption takes place, Parent and Purchaser will continue to be liable jointly and severally with such Subsidiary or Affiliate, as the case may be, for all of their respective obligations hereunder. Without limitation of the foregoing, Parent shall be entitled, subject to the terms and conditions of this Section 9.5(a), to assign prior to the Effective Time, should Parent elect to do so and by providing prompt written notice to the other Parties, to either Parent or any wholly-owned

direct or indirect Subsidiary of Parent the rights and obligations of Purchaser, as the original purchaser under this Agreement and to substitute either itself or such other wholly-owned Subsidiary as the “Purchaser” under the Plan of Arrangement. This Agreement will be binding on and will enure to the benefit of the Parties and their respective successors and permitted assigns.

(b) This Agreement (including the schedules hereto), and the Confidentiality Agreement constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof and thereof. Except as expressly permitted by the terms hereof, neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned by any of the Parties without the prior written consent of all of the other Parties.

Section 9.6. Severability

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law or public policy, all other conditions and provisions of this Agreement will nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties will negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

Section 9.7. No Third Party Beneficiaries

Except as provided in Section 7.9, and except for the rights of the holders of Peak Common Shares and Peak Options to receive the consideration for their Peak Common Shares and Peak Options following the Effective Time pursuant to the Arrangement, which rights are hereby acknowledged and agreed by the Parties, this Agreement is not intended to confer any rights or remedies upon any Person other than the Parties to this Agreement.

Section 9.8. Rules of Construction

The Parties to this Agreement have been represented by counsel during the negotiation and execution of this Agreement and waive the application of any Laws or rule of construction providing that ambiguities in any agreement or other document will be construed against the Party drafting such agreement or other document.

Section 9.9. Counterparts, Execution

This Agreement may be executed in two or more counterparts, each of which will be deemed to be an original but all of which together will constitute one and the same instrument. The Parties will be entitled to rely upon delivery of an executed facsimile or similar executed electronic copy of this Agreement, and such facsimile or similar executed electronic copy will be legally effective to create a valid and binding agreement among the Parties.

After the Effective Time, each certificate formerly representing Peak Common Shares shall represent only the right to receive the Cash Consideration the holder of Peak Common Shares represented by the certificate is entitled to in accordance with the terms of the Arrangement (less any amounts withheld pursuant to section 3.6) upon such holder depositing with the Depositary the certificate and such other documents and instruments as the Depositary may reasonably require.

3.2 Payment of Consideration.

(a) At the Effective Time, Parent and Purchaser shall cause to be deposited, on behalf of Purchaser, with the Depositary and to be held in escrow for the benefit of the holders of Peak Common Shares and holders of Peak Options, cash in the aggregate amount equal to the payments required by section 2.4(a) and section 2.4(c). The cash deposited in respect of the payments required by section 2.4(c) shall constitute the Option Payment

Loan. All cash deposited with the Depositary shall be held in an interest-bearing account and any interest earned on such funds shall be for the account of Purchaser.

(b) Upon surrender to the Depositary for transfer to Purchaser of a certificate which immediately prior to the Effective Time represented Peak Common Shares and in respect of which the holder is entitled to receive Cash Consideration under the Arrangement, together with a duly completed Letter of Transmittal and such other documents and instruments as would have been required to effect the transfer of Peak Common Shares formerly represented by such certificate under the ABCA and the by-laws of Peak, and such additional documents and instruments as the Depositary may reasonably require, the holder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such holder, the Cash Consideration (less any amounts withheld pursuant to Section 3.6), and any certificates so surrendered shall be transferred to Purchaser. No interest shall be paid to holders of certificates that formerly represented Peak Common Shares in respect of the Cash Consideration.

(c) Upon the written instruction of Peak, the Depositary shall deliver to each holder of Peak Options, if any, with an Exercise Price less than the Cash Consideration, the amount of cash such holder, if any, is entitled to under section 2.4(c) (less any amounts withheld pursuant to section 3.6). No interest shall be paid to holders of Peak Options in respect of any cash payable to such holders under section 2.4(c).

3.3 Lost Certificate. If any certificate, which immediately prior to the Effective Time represented Peak Common Shares, has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder of such Peak Common Shares claiming such certificate to be lost, stolen or destroyed, the Depositary, in respect of Peak Common Shares, will issue in exchange for such lost, stolen or destroyed certificate the consideration deliverable to such holder in respect of such lost, stolen or destroyed certificate under section 2.4(a). When authorizing such payment in exchange for any lost, stolen or destroyed certificate, the Person to whom the consideration is to be delivered shall, as a condition precedent to the delivery of such consideration, give a bond satisfactory to Purchaser and the Depositary, acting reasonably, in such sum as Purchaser may direct, or otherwise indemnify Purchaser, Peak and the Depositary, in a manner satisfactory to Purchaser, Peak and the Depositary, acting reasonably, against any claim that may be made against Purchaser, Peak or the Depositary, with respect to the certificate alleged to have been lost, stolen or destroyed.

3.4 Dividends and Other Payments. After the Effective Time, holders of Peak Common Shares shall not be entitled to any interest, dividend, premium or other payment on or with respect to Peak Common Shares other than the consideration which they are entitled to receive pursuant to the terms of the Arrangement.

3.5 Extinguishment of Rights. Any certificate formerly representing Peak Common Shares that is not deposited with all other documents required hereunder on or before the sixth anniversary of the Effective Date shall cease to represent a right or claim of any kind or nature, and the right of the holder of Peak Common Shares represented by any such certificate to receive consideration pursuant to the Arrangement shall be deemed to be surrendered to Parent together with all dividends, distributions and any interest thereon held for such holder.

3.6 Withholding Rights. Peak, Parent, Purchaser and the Depositary shall be entitled to deduct and withhold from any dividend, price or consideration otherwise payable to any holder of Peak Common Shares or Peak Options such amounts as Peak, Parent, Purchaser or the Depositary is required to deduct and withhold with respect to such payment under the Tax Act, or any provision of federal, provincial,

territorial, state, local or foreign tax law, in each case as amended. 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 securities in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. Peak, Parent, Purchaser and the Depositary are hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to Peak, Parent, Purchaser and the Depositary, as the case may be, to enable it to comply with such deduction or withholding requirement, and Peak, Parent, Purchaser or the Depositary shall notify the holder thereof and remit to such holder any unapplied balance of the net proceeds of such sale.
