(ii) the GP Board determines in good faith, after consultation with its outside legal and financial advisors, that such Partnership Acquisition Proposal constitutes, or would reasonably be expected to lead to, a Superior Proposal and that, based on the advice of outside counsel, the failure to take such action would be inconsistent with its fiduciary duties under applicable Laws and the Partnership Agreement;

(iii) prior to providing any information or data in respect of any of the Partnership Entities or the Partnership Subsidiaries, the Partnership receives from the

Person making the Partnership Acquisition Proposal an executed confidentiality agreement that contains provisions that are not less favourable to the Partnership than those contained in the Confidentiality Agreement including a standstill provision and the Partnership Entities promptly and in any event not less than 24 hours after its execution send a copy of any such confidentiality agreement to the Purchaser; and

The GP Board will review any written definitive proposal by the Purchaser to amend the terms of the Arrangement in order to determine, in good faith in the exercise of its fiduciary duties and consistent with Section 4.13(a), whether the Purchaser’s written definitive proposal to amend the Arrangement would result in the Partnership Acquisition Proposal not being a Superior Proposal compared to the proposed amendment to the terms of the Arrangement. If the GP Board determines that a Partnership Acquisition Proposal is not a Superior Proposal as compared to the proposed written definitive amendment to the terms of the Arrangement, it will promptly enter into the proposed written definitive amendment to the Arrangement.

(i) the Cash Consideration; or

(ii) the Share Consideration,

as elected or deemed to be elected by the Partnership Unitholder pursuant to Section 2.5, but subject in all respects to adjustment pursuant to Section 2.4. If a Partnership Unitholder is deemed pursuant to Section 2.4 to receive both cash and Purchaser Shares in exchange for its Partnership Units, the cash and Purchaser Shares payable to such holder shall be allocated equally among each Partnership Unit transferred to the Purchaser.

2.4 Maximum Cash Amount and Maximum Share Amount.

(a) With respect to the Cash Consideration, the aggregate amount of cash available is limited to $506,513,834 (the “ Aggregate Cash Maximum ”). If the Aggregate Cash Elected exceeds the Aggregate Cash Maximum, notwithstanding any election to receive the Cash Consideration, the aggregate amount of cash paid to each Partnership Unitholder that made an election to receive the Cash Consideration and to CPLP if it made an election to receive the Cash Consideration shall be pro-rated (based on the

fraction equal to the Aggregate Cash Maximum divided by the Aggregate Cash Elected) so that the aggregate amount of cash payable (excluding the amount payable pursuant to Section 2.3(k)) to all such Partnership Unitholders and CPLP shall be equal to the Aggregate Cash Maximum (the amount of the reduction in cash payable to any Partnership Unitholder or CPLP being the “ Cash Reduction ” in respect of such holder). In lieu of the amount of cash equal to the Cash Reduction in respect of a Partnership Unitholder or CPLP, each such Partnership Unitholder and CPLP shall receive a number of Purchaser Shares equal to the product of (i) the Cash Reduction divided by the Cash Consideration per Partnership Unit and (ii) the Exchange Ratio.

If the Aggregate Shares Elected exceeds the Aggregate Share Maximum, notwithstanding any election (or deemed election under Section 2.5(b)) to receive the Share Consideration, the aggregate number of Purchaser Shares issued to each Partnership Unitholder that made or was deemed to make an election to receive the Share Consideration and to CPLP if it made or was deemed to make an election to receive the Share Consideration shall be pro-rated (based on the fraction equal to the Aggregate Share Maximum divided by the Aggregate Shares Elected) so that the aggregate number of Purchaser Shares issuable to all such Partnership Unitholders and CPLP shall be equal to the Aggregate Share Maximum (the reduction in the number of Purchaser Shares payable to any Partnership Unitholder or CPLP being the “ Share Reduction ” in respect of such holder). In lieu of the number of Purchaser Shares equal to the Share Reduction in respect of a Partnership Unitholder or CPLP, each such Partnership Unitholder and CPLP shall receive an amount of cash equal to the product of (i) the Share Reduction divided by the Exchange Ratio and (ii) the Cash Consideration per Partnership Unit.

(c) If CPLP elects to receive Share Consideration, it shall receive that number of Purchaser Shares equal to (i) the product of (A) the Exchange Ratio and (B) the number of Partnership Units held by the Corporation and GP at the Effective Time, (ii) less the product of (Y) the principal amount of the Purchaser Note divided by the Cash Consideration per Partnership Unit and (Z) the Exchange Ratio;

course dividends), consolidation, reorganization, recapitalization or other like change with respect to Purchaser Shares, Partnership Units or Corporation Shares occurring after the date of the Arrangement Agreement and prior to the Effective Time.
