each Company Shareholder shall make such election by depositing with the Depositary, prior to the Election Deadline, a duly and properly completed Letter of Transmittal and Election Form indicating such holder’s election, together with certificates representing such holder’s Company Shares; and

any Company Shareholder who does not deposit with the Depositary a duly and properly completed Letter of Transmittal and Election Form prior to the Election Deadline, or otherwise fails to comply with the requirements of Section 3.3(a) and the Letter of Transmittal and Election Form or to elect to receive Cash Elected Consideration, Combination Elected Consideration or Unit Elected Consideration in respect of their Company Shares, shall be deemed to have elected to receive Combination Elected Consideration.

With respect to the exchange of Company Shares effected pursuant to Section 3.1(i)(i)3.1(i)(i):

each Company Shareholder shall receive, in respect of each Company Share held, the Consideration, subject to Sections 5.8 and 5.9 and Article 6 [Withholdings]; and

any Letter of Transmittal and Election Form, once deposited with the Depositary, shall be irrevocable and may not be withdrawn by a Company Shareholder.

Each registered Company Shareholder may exercise Dissent Rights with respect to the Company Shares held by such registered Company Shareholder in connection with the Arrangement. Dissenting Shareholders shall be deemed to have transferred the Company Shares held by them and in respect of which Dissent Rights have been validly exercised free and clear of all Liens as provided in Section 3.1 and if they:

are ultimately entitled to be paid fair value for their Company Shares, shall: (i) be deemed not to have participated in the transactions in Section 3.1, other than the transaction in Section 3.1(b) pursuant to which such Company Shares are transferred to, and acquired by, the Company; (ii) be entitled to be paid an amount equal to such fair value by the Company; and (iii) not be entitled to any other payment or consideration, including any payment that would be payable under the Arrangement had such Dissenting Shareholders not exercised their Dissent Rights in respect of such Company Shares; or

are ultimately not entitled, for any reason, to be paid fair value for their Company Shares, shall be deemed to have: (i) participated in the Arrangement, as of the Effective Time, on the same basis as a Company Shareholder who did not exercise its Dissent Rights and thereby to have transferred such Company Shares to the Purchaser; and (ii) elected, for the purposes of Section 3.1(i)(i), to receive Combination Elected Consideration.

The fair value of the Company Shares for the purposes of Section 4.1(a) shall be determined as of the close of business on the last Business Day immediately prior to the day on which the Arrangement Resolution is approved by the Company Shareholders.

In no event shall the Purchaser or the Company be required to recognize any Dissenting Shareholder as a Company Shareholder after the Effective Time and the names of such holders shall be removed from the register of Company Shareholders as at the Effective Time.

In no circumstances shall the Company or the Purchaser Parties or any other Person be required to recognize a Person exercising Dissent Rights unless such Person is the registered holder of those Company Shares in respect of which such rights are sought to be exercised. For greater certainty, Company Incentive Holders shall not be entitled to exercise Dissent Rights in respect of their Company Incentives.

For greater certainty, in addition to any other restrictions in section 191 of the ABCA, any Person who has voted (including by way of instructing a proxy holder to vote) their Company Shares in favour of the Arrangement Resolution shall not be entitled to exercise Dissent Rights. A registered Company Shareholder may only exercise Dissent Rights in respect of all, and not less than all, of its Company Shares.

Notwithstanding subsection 191(5) of the ABCA, the written notice setting forth such registered Company Shareholder’s objection to the Arrangement Resolution must be received in accordance with the Interim Order by no later than 5:00 p.m. (Calgary time) on the fifth Business Day immediately prior to the date of the Company Meeting (as it may be adjourned or postponed from time to time).

Deposit of Consideration

Delivery of Consideration by Depositary

Promptly following the Effective Time, upon receipt of the irrevocable direction and the cash delivered by the Purchaser Parties pursuant to Section 5.1, the Depositary shall cause a cheque or wire transfer representing the aggregate Cash Consideration and one or more certificates representing the Consideration Units that a Company Shareholder has the right to receive under the Arrangement for Company Shares, less any amounts withheld pursuant to Article 6, to be forwarded to those Persons who have deposited with the Depositary the certificates for Company Shares, if any, a Letter of Transmittal and Election Form and such documents and instruments as the Depositary may reasonably require.

The 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 the Purchaser.

The Depositary shall register the Consideration Units in the name of each Company Shareholder entitled thereto or otherwise as instructed in the Filed Letter of Transmittal and Election Form deposited by such Company Shareholder.

any and all rights related to Company Shares issued or outstanding prior to the Effective Time; and

any and all rights related to Company Incentives that are outstanding at the Effective Time and the terms and conditions thereof, including the terms and conditions of the applicable Company Incentive Plan and any agreement, certificate or other instrument granting or confirming the grant of, or representing, a Company Incentive.

the rights and obligations of the Company, the Purchaser Parties, the Depositary, the Company Securityholders (including Dissenting Shareholders) and any trustee, transfer agent or other depositary therefor, shall be solely as provided for in this Plan of Arrangement; and

all actions, causes of action, claims or proceedings (actual or contingent, and whether or not previously asserted) based on or in any way relating to any Company Shares or Company Incentives shall be deemed to have been settled, compromised, released and determined without liability except as set forth in this Plan of Arrangement.

Each of the Company , the Purchaser and the Depositary shall be entitled to deduct and withhold from the amounts otherwise payable to any Person under this Plan of Arrangement or any amount contemplated herein, such amounts as it is required, or reasonably believes it is required, to deduct and withhold with respect to such payment under the Income Tax Act (Canada) or any provision of Applicable Law (including any proposed change of Applicable Law and any applicable assessing practices or administrative policies of a Governmental Authority) and remit such deduction and withholding amount to the appropriate Governmental Authority. To the extent that amounts are so properly deducted, withheld and remitted, such deducted, withheld and remitted amounts shall be treated for all purposes of the Arrangement Agreement and the Arrangement as having been paid to such Person in respect of which such deduction and withholding and remittance was made.

The Purchaser Parties and the Company may amend, modify and/or supplement this Plan of Arrangement at any time and from time to time prior to the Effective Time, provided that each such amendment, modification and/or supplement must be: (i) set out in writing; (ii) approved by the Purchaser Parties and the Company; (iii) filed with the Court and, if made following the Company Meeting, approved by the Court subject to Sections 7.4 and 7.5); and (iv) communicated to the Company Securityholders if and as required by the Court.

Any amendment, modification or supplement to this Plan of Arrangement may be proposed by the Purchaser Parties or the Company at any time prior to or at the Company Meeting (provided that the other Parties shall have consented thereto) with or without any other prior notice or communication, and if so proposed and accepted by Persons voting at the Company Meeting (other than as may be required under the Interim Order), shall become part of this Plan of Arrangement for all purposes.

Any amendment, modification or supplement to this Plan of Arrangement that is approved or directed by the Court following the Company Meeting and prior to the Effective Time shall be effective only: (i) if it is consented to in writing by each of the Purchaser Parties and the Company (each acting reasonably); and (ii) if required by the Court, it is consented to by the Company Shareholders, voting in the manner directed by the Court.

Any amendment, modification or supplement to this Plan of Arrangement may be made by the Purchaser Parties and the Company (upon their mutual agreement) without the approval of or communication to the Court or the Company Shareholders, provided that it concerns a matter which, in the reasonable opinion of the Purchaser Parties and the Company, is of an administrative or ministerial nature required to better give effect to the implementation of this Plan of Arrangement and is not materially adverse to the economic interest of any Company Shareholders.

Any amendment, modification or supplement to this Plan of Arrangement may be made following the Effective Date unilaterally by the Purchaser Parties provided that it concerns a matter which, in the reasonable opinion of the Purchaser Parties, is of an administrative or ministerial nature required to better give effect to the implementation of this Plan of Arrangement and is not adverse to the economic interest of any former holder of Company Shares.

Notwithstanding that the transactions and events set out in this Plan of Arrangement shall occur and shall be deemed to occur in the order set out in this Plan of Arrangement without any further act or formality, each of the parties to the Arrangement Agreement shall make, do and execute, or cause to be made, done and executed, all such further acts, deeds, agreements, transfers, assurances, instruments or documents as may reasonably be required by either of them in order to further document, give effect to or evidence any of the transactions or events set out in this Plan of Arrangement or otherwise to carry out the full intent and meaning of this Plan of Arrangement.
