Participant pursuant to Section 7.1(a) and the Participant’s obligation to indemnify EMCLP pursuant to Section 7.2(a) shall be applicable only if the Participant’s Net or EMCLP’s Losses, as applicable, are in excess of

$58,670,789 (the “EMCLP Maximum Indemnity Limit”) and, in addition to not exceeding the Participant Maximum Indemnity Limit or EMCLP Maximum Indemnity Limit, as applicable: 

(a) EMCLP’s obligation to indemnify the Participant for Losses suffered or incurred as result of any inaccuracy or

$18,189,598 (the “Participant Reduced Indemnity Limit”). 
 - 45 - 







 



 
  
 If the
aggregate of all of the Participant’s Losses or all of EMCLP’s Losses, as applicable, exceeds the Threshold, the Participant or EMCLP, as applicable, shall be obliged to indemnify the other for all of those Losses, including the amount of
the Threshold, but only up to Participant Maximum Indemnity Limit or EMCLP Maximum Indemnity Limit, as applicable, or, to the extent that Section 7.3(l)(a) or 7.3(l)(b) applies, only up to the EMCLP Reduced Indemnity Limit or Participant
Reduced Indemnity Limit, as applicable. 
 (2) Subject to Section 7.3(1), only items or Claims exceeding
$25,000 shall be included in the calculation of Losses for the purpose of the Threshold, except that for the purpose of determining whether a Party is entitled to indemnification under this Agreement, a group of related matters resulting in Losses
arising out of the same or a similar event or occurrence or a series of related or similar events or occurrences shall be deemed to be one item or Claim. 
 (3) The provisions of Sections 7.3(1) and 7.30 shall not apply in respect of any inaccuracy or breach of a representation or warranty involving fraud or fraudulent misrepresentation.

 (4) For the purposes of this Section 7.3:

aware of any circumstances which have given or could give rise to a Claim of indemnification under this Article 7, the Party claiming indemnification (the “Indemnified Party”) shall notify the other Party (the “Indemnifying
Party”) of those circumstances. That notice shall specify whether the Losses arise as a result of a Claim by a Person (other than a Party) against the Indemnified Party (a “Third Party Claim”) or whether the Losses do not so arise (a
“Direct Claim”), and shall also specify with reasonable particularity (to the extent the information is available) the factual basis for the Claim and the amount of the Losses, if known. 

(2) If through the fault of the Indemnified Party, the Indemnifying Party does not receive notice of any Claim in time to
contest effectively the determination of any liability susceptible of being contested, the Indemnifying Party shall be entitled to set off against the amount claimed by the Indemnified Party the amount of any Losses incurred by the Indemnifying
Party resulting from the Indemnified Party’s failure to give that notice on a timely basis. 
 7.5 Direct
Claims. With respect to any Direct Claim, following receipt of notice from the Indemnified Party of the Direct Claim, the Indemnifying Party shall have 60 days to make such investigation of the Direct Claim as is considered necessary or desirable.

 - 46 - 







 



 
  
 exclusive
basis the information relied on by the Indemnified Party to substantiate the Direct Claim, together with such information as the Indemnifying Party may reasonably request. If the Parties agree at or prior to the expiry of this 60 day period (or to
any agreed extension of this period) to the validity and amount of that Direct Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full amount as agreed to by the Parties of the Direct Claim, For clarity, (i) the
Participant shall be deemed to have incurred or suffered Losses as of and from the Effective Time as a consequence of any reduction in the value of the SD Transfer Rights resulting from an inaccuracy or breach of any representation or warranty by
EMCLP under this Agreement and (ii) EMCLP shall be deemed to have incurred or suffered Losses as of and from the Effective Time as a consequence of any reduction in the value of the BR Swap Rights resulting from an inaccuracy or breach of any
representation or warranty by the Participant under this Agreement. 
 7.6 Third Party Claims. 

(1) With respect to any Third Party Claim, the Indemnifying Party shall be entitled (but not required), at its expense, to
participate in or assume the conduct of the negotiations, settlement or defence of the Third Party Claim and, if it does, the Indemnifying Party shall reimburse the Indemnified Party for all of the Indemnified Party’s out-of-pocket expenses as
a result of that participation or assumption, 
 (2) If the Indemnifying Party elects to assume the conduct of
the negotiations, settlement or defence of the Third Party Claim, the Indemnifying Party shall be entitled to retain counsel on behalf of the Indemnified Party who is acceptable to the Indemnified Party, acting reasonably, to represent the
Indemnified Party in the negotiation, settlement or defence of that Third Party Claim. In any Third Party Claim for which the Indemnifying Party elects to assume that conduct, the Indemnified Party shall have the right to participate in the
negotiation, settlement or defence of that Third Party Claim and to retain separate counsel to act on its behalf but the fees and disbursements of that counsel shall be at the expense of the Indemnified Party unless: 

(a) the Indemnified Party determines, acting reasonably, that actual or potential of conflicts of interests exist which
make representation chosen by the Indemnifying Party not advisable (such as where the named parties to that Third Party Claim include both the Indemnifying Party and the Indemnified Party, and the defences available to the Indemnified Party are
different or in addition to those available to the Indemnifying Party); or 
 (b) the Indemnifying Party has
authorized the retention of that counsel; 
 in each of which cases the fees and disbursements of such counsel
shall be at the expense of the Indemnifying Party. 
 (3) If the Indemnifying Party, having elected to assume
that conduct, thereafter fails to defend the Third Party Claim diligently, the Indemnified Party shall be entitled to assume that conduct, and the Indemnifying Party shall be bound by the results obtained by the Indemnified Party with respect to
that Third Party Claim. If any Third Party Claim is of a 
 - 47 - 







 



 
  
 nature
such that the Indemnified Party is required by Applicable Law to make a payment to any Person (a “Third Party”) with respect to the Third Party Claim before the completion of settlement negotiations or related legal proceedings, the
Indemnified Party shall provide prior written notice of that payment to the Indemnifying Party and thereafter may make that payment and the Indemnifying Party shall, forthwith after demand by the Indemnified Party, reimburse the Indemnified Party
for that payment. If the amount of any liability of the Indemnified Party under the Third Party Claim in respect of which that payment was made, as finally determined, is less than the amount that was paid by the Indemnifying Party to the
Indemnified Party, the Indemnified Party shall, forthwith after receipt of the difference from the Third Party, pay the amount of that difference to the Indemnifying Party. 
 7.7 Settlement of Third Party Claims. If the Indemnifying Party fails to assume conduct of the defence of any Third Party Claim, the Indemnified Party shall have the exclusive right to
contest, settle or pay the amount claimed. Whether or not the Indemnifying Party assumes conduct of the negotiation, settlement or defence of any Third Party Claim, the Indemnifying Party shall not settle any Third Party Claim without the written
consent of the Indemnified Party, which consent cannot be unreasonably withheld or delayed, and the liability of the Indemnifying Party to the Indemnified Party shall be limited to the amount of the Indemnified Party’s liability under any
proposed settlement that could have been effected for which the Indemnified Party’s consent was not obtained. 
 7.8 Co-Operation. The Indemnified Party and the Indemnifying Party shall co-operate fully with each other with respect to Third Party Claims, and shall keep each other fully advised with
respect to Third Party Claims (including supplying copies of all relevant documentation promptly as it becomes available). Where the defence of a Third Party Claim is being undertaken and conducted by the Indemnifying Party, the Indemnified Party
shall use all reasonable efforts to make available to the Indemnifying Party, at the request and expense of the Indemnifying Party, those employees of the Indemnified Party whose assistance, testimony or presence is reasonably necessary to assist
the Indemnifying Party in evaluating and defending that Third Party Claim. 
 7.9 Gross-up. If an Indemnified
Party is subject to Tax in respect of the receipt of an amount pursuant to this Article 7, after taking into account any offsetting deduction or tax credit available in respect of the applicable Losses, then the amount payable by the Indemnifying
Party shall be increased by an amount (the “Increased Amount”) such that the Indemnified Party shall be in the same position after paying Tax on the amount received hereunder, including any Taxes payable on the Increased Amount, as the
Indemnified Party would have been in had the Losses giving rise to such payment not arisen and had such amount not been payable. 
 7.10 Exclusivity. Unless otherwise provided in this Agreement, the provisions of this Article 7 shall apply to any Claim for breach of covenants, representation, warranty or other
obligation or provision of this Agreement or any Contract, instrument, certificate or other document delivered pursuant to this Agreement (other than a Claim for specific performance or injunctive relief) and to any and all other indemnities
provided in this Agreement or in any Contract, instrument, certificate or other document delivered pursuant to this Agreement with the intent 
 - 48 -

Party shall make any public statement or issue any press release concerning the Transactions except as agreed by the Parties acting reasonably or as may be necessary, in the opinion of counsel to the Party making that disclosure, to comply with the
requirements of all Applicable Law or the rules of any securities exchange or securities regulatory body having jurisdiction over the Party or its Affiliates. If any public statement or release is so required, the Party making the disclosure shall

agreement between the Parties pertaining to the subject matter of this Agreement and the Other Agreements and supersede all prior correspondence, agreements, negotiations, discussions and understandings, written or oral. Except as specifically set
out in this Agreement or the Other Agreements, there are no representations, warranties, conditions or other agreements or acknowledgements, whether direct or collateral, express or implied, written or oral, statutory or otherwise, that form part of
or affect this Agreement or the Other Agreements or which induced any Party to enter into this Agreement or the Other Agreements. No reliance is placed on any representation, warranty, opinion, advice or assertion of fact made either prior to,

right under this Agreement shall operate as a waiver of that right. No single or partial exercise of any such right shall preclude any other or further exercise of that right or the exercise of any other right.

the province of Alberta.

shall have any knowledge or notice thereof) which might otherwise constitute a legal or equitable discharge or defence of a guarantor; provided that any claim hereunder against EMCLP’s Guarantor shall be subject to, and EMCLP’s Guarantor
