Limitation on the Corporation’s Business

Governance

Share Purchase Agreement

The Parties acknowledge that, concurrently with the execution of this Agreement, the Corporation has entered into the Share Purchase Agreement and the Debt Commitment Letter.

Each of KKR and SemGroup shall (to the extent within its control) cause the Corporation to use its commercially reasonable efforts to consummate the Meritage Closing as soon as reasonably practicable after the date of this Agreement on the terms described in the Share Purchase Agreement, which shall include (to the extent within its control) causing the Corporation to: (i) maintain in full force and effect the Share Purchase Agreement; (ii) comply with the obligations of the Corporation under the Share Purchase Agreement; (iii) satisfy on a timely basis all conditions in the Share Purchase Agreement that are within its control; and (iv) fully enforce the Corporation’s rights under the Share Purchase Agreement, in each case unless otherwise agreed to in writing by KKR and SemGroup. If the conditions to the

The Corporation shall provide to KKR and SemGroup prompt notice of: (i) any breach or threatened breach by any party of the Share Purchase Agreement of which the Corporation becomes aware; (ii) any termination or threatened termination of the Share Purchase Agreement; and (iii) any material dispute or disagreement between or among any parties to the Share Purchase Agreement. As soon as reasonably practicable, KKR and SemGroup shall provide any information reasonably requested by any Party and that is reasonably available to KKR or SemGroup, as applicable, relating to any circumstance referred to in clause (i), (ii) or (iii) of the immediately preceding sentence. Each Party shall keep the other Parties informed on a reasonably current basis and in reasonable detail of all material developments concerning the status of the Meritage Closing and provide such other Parties with copies of the information and documentation available to them as shall be reasonably requested by such other Parties for purposes of monitoring the progress of the Meritage Closing. No Party shall permit any amendment, modification or supplement to be made to, or any waiver of, any provision or remedy under the Share Purchase Agreement, without the prior written consent of each other Party.

Payment of SPA Deposit

The Parties acknowledge that: (i) concurrently with, or promptly after, the execution of the Share Purchase Agreement, SemGroup and KKR, respectively, have paid, or shall pay within the timeframe contemplated by the terms thereof, the SemGroup Deposit Amount and the KKR Deposit Amount to the Escrow Agent on account of the Corporation’s obligation to pay the SPA Deposit pursuant to the Share Purchase Agreement; and (ii) such payments were made, or shall be made, on the direction of the Corporation and constitute, or shall constitute, capital contributions to the Corporation by KKR and SemGroup, respectively, in respect of which each Party was, or shall be, issued one (1) Common Share for each $1.00 of contribution it made.

Subject to Sections 3.2(c) and 3.2(d), if the Meritage Closing does not occur and the SPA Deposit is returned (in whole or in part) to the Corporation, any amount of the SPA Deposit received by the Corporation (including any interest earned on the SPA Deposit while held by the Escrow Agent) shall forthwith be returned to KKR and SemGroup by way of return of capital to the extent possible and then by way of a dividend of 51% such amount to SemGroup and 49% of such amount to KKR, in their respective capacities as holders of Common Shares. If, for any reason, KKR or SemGroup is in receipt of any amounts in excess of that which it would otherwise be entitled to pursuant to the foregoing sentence, it shall forthwith make the necessary payments to the other of them such that each of them shall have received their pro rata entitlements to the amount of the SPA Deposit and interest earned on the SPA Deposit while held by the Escrow Agent returned to the Corporation.

In the event that the Meritage Closing does not occur as a result of a breach by KKR of its representations, warranties or covenants under this Agreement (including circumstances where SemGroup does not complete the Contribution Closing because the conditions set forth in Section 6.1 or 6.3 are not satisfied as a result of a breach by KKR of its representations, warranties or covenants under this Agreement), and all or a portion of the SPA Deposit is retained by Meritage pursuant to the Share Purchase Agreement, KKR shall pay to SemGroup an amount equal to the SemGroup Deposit Amount as liquidated damages and not as a penalty as a result of the Meritage Closing and the Contribution Closing not occurring. The remedy set forth in the immediately preceding sentence shall be the sole and exclusive remedy of any Party against KKR in the event of termination of this Agreement.

In the event that the Meritage Closing does not occur as a result of a breach by SemGroup of its representations, warranties or covenants under this Agreement (including circumstances where KKR does not complete the Contribution Closing because the conditions set forth in Section 6.1 or 6.2 are not satisfied as a result of a breach by SemGroup of its representations, warranties or covenants under this Agreement), and all or a portion of the SPA Deposit is retained by Meritage pursuant to the Share Purchase Agreement, SemGroup shall pay to KKR an amount equal to the KKR Deposit Amount as liquidated damages and not as a penalty as a result of the Meritage Closing and the Contribution Closing not occurring. The remedy set forth in the immediately preceding sentence shall be the sole and exclusive remedy of any Party against SemGroup in the event of termination of this Agreement.

In the event that the Meritage Closing does not occur as a result of circumstances such that a payment is required under both of Sections 3.2(c) and 3.2(d), then neither SemGroup nor KKR shall be entitled to claim for damages. For greater certainty, in such circumstances, Section 3.2(b) would continue to apply to the return of all or any part of the SPA Deposit to the Corporation.

Except as a result of a breach of this Agreement, in no event shall the Corporation or any other Party be liable to KKR or SemGroup for any interest on the KKR Deposit Amount or the SemGroup Deposit Amount, respectively, or for any amount of the SPA Deposit not returned by Meritage.

The obligations of the Parties in this Section 3.2 shall survive termination of this Agreement.

The number of Common Shares to be issued to KKR and SemGroup at the Contribution Closing shall be correspondingly adjusted, having regard to the principle that each of SemGroup and KKR are to be issued Common Shares on a $1.00 per share basis for the net value contributed by each of them, respectively.

Within five (5) Business Days after the date on which the amounts specified in the Working Capital Statement are finally determined pursuant to Section 4.7:

if the Net Value Adjustment specified in the Working Capital Statement as finally determined pursuant to Section 4.7 is less than the Estimated Net Value Adjustment, SemGroup shall pay or cause to be paid to the Corporation by wire transfer of immediately available funds an amount equal to the difference as a decrease in respect of the Consideration Cash; and

if the Net Value Adjustment specified in the Working Capital Statement as finally determined pursuant to Section 4.7 is greater than the Estimated Net Value Adjustment, the Corporation shall pay or cause to be paid to SemGroup by wire transfer of immediately available funds an amount equal to the difference as an increase in respect of the Consideration Cash.

The Parties shall work together in good faith to assess and agree upon whether to fund the Additional Transaction Expenses payable by the Corporation at the Closing Time by increasing the amount drawn on debt facilities at the Debt Financing Closing or through additional equity contributions by KKR and SemGroup to the Corporation. In the event that the Parties are unable to reach

Working Capital Statement

As soon as practicable and in any event no later than February 15, 2019, SemGroup shall prepare and deliver to KKR a statement which includes calculations of the Net Value Adjustment as of December 31, 2018, based on actual amounts, and any required adjustment to the KKR Contribution and the Consideration Cash in accordance with Section 4.5 (the “Working Capital Statement”). Each amount included in the Working Capital Statement shall be calculated in accordance with this Agreement and be accompanied by reasonable supporting detail to evidence SemGroup’s calculations, explanations and assumptions for the calculation of such amounts.

Following receipt of the Working Capital Statement, KKR will have thirty (30) days to review it (the “Review Period”). During the Review Period, SemGroup shall assist KKR in reviewing and verifying the Working Capital Statement and make any revisions thereto reasonably required as a result of such review and shall ensure that KKR and its Representatives are given full access, upon every reasonable request, to the supporting documentation of SemGroup prepared in connection with the preparation of the Working Capital Statement to verify the accuracy, presentation and other matters relating to the preparation of the Working Capital Statement, and to enable KKR to exercise its rights under Section 4.7.

SemGroup and KKR shall each bear their own fees and expenses, including the fees and expenses of their respective accountants, in preparing or reviewing, as the case may be, the Working Capital Statement. If a dispute regarding the Working Capital Statement is submitted for determination to the Independent Accountant under Section 4.7, the fees and expenses of the Parties and the Independent Accountant will be paid in accordance with Section 4.7.

Acceptance or Dispute of the Working Capital Statement

Following receipt of the Working Capital Statement as contemplated by Section 4.6, if KKR objects in good faith to any item on the Working Capital Statement, KKR shall so notify SemGroup delivering to SemGroup a written Notice to that effect (the “Notice of Objection”) prior to the end of the Review Period. The Notice of Objection must set out the reasons for KKR’s objection, each item and amount in dispute and reasonable details of the calculation of that amount. If KKR does not object to any item of the Working Capital Statement, KKR may so notify SemGroup by delivering a written Notice to that effect (the “Notice of Acceptance”).

If KKR does not deliver a Notice of Objection or Notice of Acceptance to SemGroup prior to the end of the Review Period, KKR will be deemed to have delivered a Notice of Acceptance to SemGroup the last day of the Review Period and the Working Capital Statement will be deemed to be final and binding for purposes of the payments referred to in Section 4.5. For greater certainty, no Party may attempt to dispute, recover, recoup, duplicate or adjust any amount which that Party is required to pay or entitled to receive as a result of the payments referred to in Section 4.5 by making a Claim for Losses under Article 10.

If KKR delivers a Notice of Objection, the Parties shall work expeditiously and in good faith to resolve all of the items in dispute set out in the Notice of Objection within thirty (30) days following delivery of the Notice of Objection. Any items in dispute (and only such items) that are not resolved by the end of that thirty (30) day period will be submitted by the Parties for determination to an independent accounting firm mutually agreed to by the Parties or, if the Parties are unable to agree on the independent accounting firm within a further three (3) Business Days, to PricewaterhouseCoopers in their Calgary, Alberta offices. In making its determination, the selected accounting firm (the “Independent Accountant”) will act as expert and not as arbitrator, must only consider the items in dispute submitted to it, and must make all reasonable efforts to determine the items in dispute no later than twenty (20) Business Days of the matter being submitted to the Independent Accountant. Each Party’s submissions to the Independent Accountant shall be made in writing and delivered to the Independent Accountant (with simultaneous copy to the other Party) within ten (10) Business Days of the matter being submitted to the Independent Accountant. There shall be no ex parte communications between a Party, on the one hand, and the Independent Accountant, on the other hand, relating to those matters in dispute, other than the initial written submissions by each Party of their respective positions on the matters in dispute and written answers by a Party to written questions from the Independent Accountant, with simultaneous copies to each Party. With respect to each disputed line item, the Independent Accountant’s determination, if not in accordance with the position of one of the Parties, shall not be in excess of the highest nor less than the lowest of the amounts advocated in any Notice of Objection or in the Working Capital Statement with respect to such disputed line item. The determination of the Independent Accountant will be final and binding upon the Parties and will not be

Notwithstanding Article 11, the procedure set out in this Section 4.7 for resolving disputes with respect to the Working Capital Statement is the sole and exclusive method of resolving those disputes, absent manifest error or Fraud. However, this Section 4.7 will not:

prohibit a Party from commencing litigation to compel specific performance of this Section 4.7 or to enforce the determination of the Independent Accountant; or

prohibit a Party from exercising its rights under Article 11, if the basis of the dispute could also entitle that Party to make a Claim for Losses under Article 10 and (a) that Claim is not discovered until after the delivery of the Working Capital Statement under Section 4.6 that Claim involves the Fraudulent act of the other Party.

Section 116 Compliance

Provided that the Contribution Closing occurs, SemGroup shall be liable for and, as a separate and independent covenant, agrees to defend, indemnify and hold harmless and release the KKR Indemnitees and the Corporation from and against, any Taxes due and owing by, and all Taxes imposed on or incurred by, SemGroup pursuant to section 116 of the Tax Act resulting from the completion of the Required Transactions and the Contribution Transaction (“SemGroup Taxes”), including any liability imposed or that may be imposed upon the KKR Indemnitees or the Corporation or both pursuant to section 116 of the Tax Act in connection therewith, including any interest or penalties that arise in connection with a failure to withhold and remit SemGroup Taxes within the timeframe prescribed by section 116(5) of the Tax Act or within the timeframe indicated by the CRA in circumstances where a comfort letter has previously been provided that extended the timeframe prescribed by section 116(5) of the Tax Act. Any payment made by SemGroup in respect of the foregoing shall not give rise to any financial or ownership interest of the SemGroup in the Corporation and shall not be an adjustment to the contributed value of the Contributed Shares and Section 10.13 shall apply to such payment, mutatis mutandis.

Concurrent with the Contribution Closing, SemGroup shall deliver to the Corporation the SemGroup Performance Guarantee (the “Security”).

The Security shall be immediately returned to SemGroup promptly following the date that SemGroup provides to KKR (i) one or more Section 116 Certificates with an aggregate certificate limit that is equal to or greater than the cost to the Corporation of the Contributed Shares (taking into account the adjustment contemplated by Sections 4.5 and 4.9 and any other adjustment hereunder to the purchase price paid by the Corporation in exchange for the SemGroup Contribution) or (ii) a certificate issued under subsection 116(4) of the Tax Act in respect of the SemGroup Contribution.

Neither the Corporation nor KKR shall withhold any amounts in respect of Taxes in respect of the SemGroup Contribution excluding amounts paid pursuant to Article 10 and excluding any withholding required under Part XIII of the Tax Act.

The Parties agree that the form and content of each of the Section 116 Certificates and the certificate issued under subsection 116(4) of the Tax Act in respect of the SemGroup Contribution, as applicable, shall be satisfactory to KKR, acting reasonably.

Post-Closing Adjustments for K3 Cogen Facility

the KKR Contribution and the Consideration Cash amount shall be increased by the amount of CAD $14,700,000 (the “KKR Additional Contribution”);

KKR shall promptly pay the Corporation the KKR Additional Contribution and the Corporation shall issue 14,700,000 Common Shares to KKR; and

as additional consideration for the SemGroup Contribution (i) in settlement of the adjustment to the Consideration Cash pursuant to Section 4.9(a), the Corporation shall pay an amount (the “K3 Adjustment Cash”) equal to the KKR Additional Contribution to SemGroup and (ii) the Corporation shall issue 15,300,000 Common Shares to SemGroup.

Enforcement by Indemnitees

Limitation of Liability

Notwithstanding any other provision contained herein, from and after the Contribution Closing, SemGroup has no Liability for, or any obligation to make any payment for, Losses (for indemnification or otherwise) in respect of the representations and warranties set forth in this Agreement, including all provisions in Section 7.2, or the other Contribution Documents, being untrue, inaccurate or incorrect, and for the purpose of Section 10.1, a breach or non-fulfillment of any agreement, term or covenant does not include that a representation or warranty made on the part SemGroup in this Agreement being untrue. KKR shall cause the representation and warranty insurance policies issued by Chubb Insurance Company of Canada, Euclid Transactional, LLC and Ethos Specialty Insurance Services, LLC in favour of the KKR Indemnitees in respect of the Contribution Transaction (the “R&W Insurance Policy”) (the cost of which shall be for the sole account of the Corporation) to be issued at the Contribution Closing (in accordance with the terms of the binder thereof) and remain in full force and effect for the term of such R&W Insurance Policy. Notwithstanding anything to the contrary contained herein, (i) the KKR Indemnitees shall not have any recourse to SemGroup for Losses as a result of, arising out of, or related to any breach of or inaccuracy in any representation or warranty of SemGroup in this Agreement or the other Contribution Documents, other than claims for Fraud, and (ii) the sole and exclusive remedy and recourse of the KKR Indemnitees and the Corporation for Losses as a result of, arising out of, or related to any breach of or inaccuracy in any representation or warranty of SemGroup in this Agreement or the other Contribution Documents, other than claims for Fraud, shall be to recover under the R&W Insurance Policy. The R&W Insurance Policy shall expressly provide that the insurer(s) issuing the R&W Insurance Policy shall waive or otherwise not pursue any subrogation rights against SemGroup and any of SemGroup’s Affiliates or any of their respective equityholders or Representatives, except in the case of Fraud, as applicable. From and after the date hereof, neither KKR nor the Corporation shall (and shall cause their respective Affiliates to not) grant any right of subrogation or otherwise amend, modify, terminate, or waive any term or condition of the R&W Insurance Policy in a manner inconsistent with the immediately preceding sentence or otherwise in a manner adverse to SemGroup, any of SemGroup’s Affiliates or any of their respective equityholders or Representatives. To the extent that SemGroup would be liable for Losses under Section 10.1 and such Losses would also be covered by the R&W Insurance Policy then KKR and the Corporation shall seek recovery under the R&W Insurance Policy first prior to making any Claims against SemGroup in respect of such matters pursuant to any right of indemnification against SemGroup arising under Section 10.1.

In the cases of Losses suffered, sustained or incurred by the KKR Indemnitees or the Corporation which SemGroup is liable hereunder, each of KKR and the

Exclusive Remedies

Notwithstanding any other provision contained herein, if the Meritage Closing does not occur:

the sole and exclusive monetary remedy of SemGroup for any misrepresentation or breach of a representation, warranty or covenant of KKR contained in any Contribution Document shall be the remedy set forth in Section 3.2(c);

the sole and exclusive monetary remedy of KKR for any misrepresentation or breach of a representation, warranty or covenant of SemGroup contained in any Contribution Document shall be the remedy set forth in Section 3.2(d); and

the Corporation shall not have any monetary liabilities to any other Party for any misrepresentation or breach of a representation, warranty or covenant contained in any Contribution Document; and

Notwithstanding any other provision contained herein, if the Meritage Closing occurs:

other than in the case of fraud by a Party, the liability and indemnification provisions of this Article 10 shall be the sole and exclusive monetary remedy of an Indemnified Party for any misrepresentation or breach of a representation, warranty or covenant of the Indemnifying Party contained in any Contribution Document;

no misrepresentation or breach of a representation, warranty or covenant shall give rise to any right on the part of any Party to rescind this Agreement, any of the Transaction Documents or any of the transactions contemplated hereby or thereby; and

neither KKR nor SemGroup shall have any liability to any Party or any Party’s Representatives under Section 5.3 or 5.4.

Notice of Claim

In the event that a Party (the “Indemnified Party”) becomes aware of any Claim it or any of its Representatives or other related indemnified Persons may have arising out of or in connection with this Agreement or the Contribution Transaction (a “Indemnity Claim”), the Indemnified Party shall promptly give notice thereof (a “Notice of Claim”) to the other Party (the “Indemnifying Party”) from whom it is seeking indemnification hereunder. Such Notice of Claim shall specify whether the Indemnity Claim arises as a result of a Claim by a Person against the Indemnified Party (a “Third Party Claim”) or whether the Indemnity Claim does not so arise, and shall also specify with reasonable particularity (to the extent that the information is available): (i) the factual basis for the Indemnity Claim; and (ii) the amount of the Indemnity Claim, if known. A failure to give prompt notice as provided in this Section 10.3 shall not affect the rights or obligations of any party except and only to the extent that, as a result of such failure, any Party which was entitled to receive such notice was directly prejudiced as a result of such failure, including should it have been deprived of its right to recover any payment under its applicable insurance coverage.

The obligations of an Indemnifying Party hereunder to indemnify the Indemnified Party in respect of any breach or inaccuracy of any representation or warranty are subject to and conditional upon the Indemnified Party providing a Notice of Claim to the Indemnifying Party in accordance with this Section 10.3.

Defence of Third Party Claims

With respect to any Third Party Claim, the Indemnifying Party shall have the right, at its expense, to participate in or assume control of the negotiation, settlement or defence of the Indemnity Claim, provided that the Indemnifying Party has acknowledged its Liability hereunder for the Indemnity Claim and any Losses arising therefrom and has furnished such security or other assurances as the Indemnified Party may reasonably request in connection therewith, and provided further that any such negotiation, settlement or defence is conducted in good faith and with due diligence, and, in such event, the Indemnifying Party shall reimburse the Indemnified Party for all of the Indemnified Party’s out-of-pocket expenses as a result of such participation or assumption. If the Indemnifying Party elects to assume such control, the Indemnified Party shall have the right to participate in the negotiation, settlement or defence of such Third Party Claim and to retain counsel to act on its behalf, provided that the fees and disbursements of such counsel shall be paid by the Indemnified Party unless the Indemnifying Party consents to the retention of such counsel or unless the named parties to any action or proceeding include both the Indemnifying Party and the Indemnified Party and representation of both the Indemnifying Party and the Indemnified Party by the same counsel would be inappropriate due to the actual or potential differing interests between them (such as the availability of different defences).

If the Indemnifying Party, having elected to assume such control, thereafter fails to defend the Third Party Claim within a reasonable time, then the Indemnified Party shall be entitled to assume such control, and the Indemnifying Party shall be bound by the results obtained by the Indemnified Party with respect to such Third Party Claim.

Notwithstanding the foregoing provisions of this Section 10.7, the Indemnified Party shall have the sole and exclusive right to participate in or assume control of the negotiation, settlement or defence of a Third Party Claim if:

the Indemnity Claim for indemnification involves or relates, directly or indirectly and in any manner whatsoever, to any present material customer or supplier of the Corporation; or

the Third Party Claim seeks any injunctive or other relief (other than monetary damages) against the Indemnified Party,

If any Third Party Claim is of a nature such that the Indemnified Party is required by Applicable Laws to make a payment to any Person other than a Party or a Party’s Affiliates and its and their Related Persons (a “Third Party”) with respect to the Third Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may make such payment and the Indemnifying Party shall, forthwith after demand by the Indemnified Party, reimburse the Indemnified Party for such payment.

If the amount of any Liability of the Indemnified Party under the Third Party Claim in respect of which such a 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 such difference to the Indemnifying Party.

Settlement of Third Party Claims

Reductions and Subrogation

If the amount of Losses incurred by an Indemnified Party or any of its Representatives or other related indemnified Persons at any time subsequent to the making of an indemnity payment hereunder is actually reduced by any recovery, settlement or otherwise under any insurance coverage or under any Claim, recovery, settlement or payment by or against any other Person, including under any manufacturer’s or other third party warranty, the Indemnified Party shall promptly repay to the Indemnifying Party the amount of the reduction (less any costs, expenses (including Taxes) or premiums incurred in connection therewith). For greater certainty, no repayment by the Indemnified Party shall be required unless, and to the extent that, the sum of the indemnity payment and the amount received from the Third Party exceeds the total amount of Losses (which was required to be paid by the Indemnified Party subject to the terms of this Agreement) to which the indemnity payment relates.

Each Indemnified Party shall use all commercially reasonable efforts to recover the full amount available to it under any such recovery, settlement or otherwise under any insurance coverage or under any Claim, recovery, settlement or payment by or against any other Person, including under any manufacturer’s or other third party warranty. For certainty, the commercially reasonable efforts of each of KKR and the Corporation pursuant to this Section 10.9(b) shall not include any efforts which, in its reasonable opinion, will materially adversely impact its business.

Upon making a full indemnity payment, the Indemnifying Party will, to the extent of that indemnity payment, be subrogated to all rights of the indemnified Person against any Third Party in respect of the Losses to which the indemnity payment relates, provided that until the Indemnified Party recovers full payment of the Losses to which the indemnity payment relates, any and all claims of the Indemnifying Party against any such Third Party on account of the indemnity payment are hereby expressly made subordinate and subject in right of payment to the Indemnified Party’s rights against such Third Party.
