- 28 -

SemCAMS has become liable, as applicable, together with interest on each relevant amount at the Interest Rate from and including the date on which the relevant amount, value or benefit was received by SemGroup or its Affiliate, or SemCAMS became liable for the relevant Taxes, as applicable, until (but excluding) the date of payment in full to SemCAMS or the Corporation, as applicable, under this Section 4.4(c); and

(iii) SemGroup shall promptly provide to KKR reasonable evidence of repayment of the amounts referenced in paragraph (ii) above.

Notwithstanding any other provision of this Agreement:

(d) For the purposes of this Section 4.4, value shall be deemed to have been removed from SemCAMS if and to the extent that SemCAMS repays Indebtedness owing by it to SemGroup or any of its Affiliates using cash.

4.5 Adjustments to the KKR Contribution and Consideration Cash

(a) The KKR Contribution and the Consideration Cash amount shall be increased by 49% of the amount of any capital contributions made by SemGroup to SemCAMS from and after the Effective Date until the receipt of the Regulatory Approvals

- 29 -

(excluding any refunds, reimbursements or other payments made pursuant to Section 4.4(c)) plus an amount equal to the interest on such portion of such capital contribution at the Interest Rate, calculated daily but not compounded for the period from (and including) the date such contribution was made to (but excluding) the date on which the Contribution Closing occurs. SemGroup shall promptly provide written notice of any such capital contribution to KKR, which notice shall include a description of the amount of such capital contribution, proposed use of proceeds and the number of Contributed Shares issued in respect thereof. The number of Common Shares to be issued to KKR and SemGroup at the Contribution Closing shall be correspondingly adjusted (provided that no adjustment shall be made in respect of any amount paid on account of interest), 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.

(b) The KKR Contribution and the Consideration Cash shall be: (i) increased by 49% of the amount, if any, by which the Net Value Adjustment as of December 31, 2018 exceeds zero dollars; or (ii) decreased by 49% of the amount, if any, by which the Net Value Adjustment as of December 31, 2018 is less than zero dollars, provided that the foregoing adjustments shall be based on the Net Value Adjustment set forth in the Working Capital Statement as prepared and delivered by SemGroup pursuant to Section 4.6 (such amount, the “Estimated Net Value Adjustment”). 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.

(c) 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:

(i) 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

(ii) 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.

(d) 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

- 30 -

agreement by the Closing Time, to the extent that the Corporation requires additional funding in order to pay the Additional Transaction Expenses, such funding will be provided by way of additional equity contributions by KKR and SemGroup to the Corporation at the Contribution Closing. In either case, (i) the KKR Contribution shall be increased by 49% of the amount, if any, of the aggregate amount of the Additional Transaction Expenses that will be funded by shareholder contributions (and KKR shall be issued one (1) Common Share for each $1.00 of contribution so made by it), and (ii) the Consideration Cash shall be decreased by 51% of the amount, if any, of the aggregate amount of the Additional Transaction Expenses that will be funded by shareholder contributions (and SemGroup shall be issued one (1) Common Share for each $1.00 of contribution so made by it). Unless otherwise agreed by Extraordinary Resolution (as defined in the Unanimous Shareholder Agreement), any Additional Transaction Expenses payable after the Closing Time will be funded through debt facilities available to the Corporation.

4.6 Working Capital Statement

(a) 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.

(b) 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.

(c) 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.

- 31 -

4.7 Acceptance or Dispute of the Working Capital Statement

(a) 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”).

(b) 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.

(c) 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

- 32 -

subject to appeal, absent manifest error, and the calculations of the Net Value Adjustment, the adjusted KKR Contribution and the adjusted Consideration Cash as determined by the Independent Accountant will be final and binding for purposes of the payments referred to in Section 4.5. For greater certainty, no Party may appeal a determination made by the Independent Accountant or 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 that determination or the payments referred to in Section 4.5 by making a Claim for Losses under Article 10. The Independent Accountant, in its sole and absolute discretion, shall determine the proportion of its fees and expenses to be paid by SemGroup, on the one hand, and KKR, on the other hand, based primarily on the degree to which the Independent Accountant has accepted the positions of the respective Parties in relation to the disputed matters.

(d) 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:

(i) 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

(ii) 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.

4.8 Section 116 Compliance

(a) 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.

- 33 -

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

(c) 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.

(d) 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.

(e) 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.

4.9 Post-Closing Adjustments for K3 Cogen Facility

KKR, SemGroup and the Corporation agree that if the Corporation reaches a positive Final Investment Decision in respect of the K3 Cogen Facility on or before May 31, 2019:

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

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

(c) 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.

To the fullest extent permitted under Applicable Laws, for all purposes (including tax purposes), the Parties shall treat the transactions under this Section 4.9 as an adjustment to the purchase price paid by the Corporation in exchange for the KKR Contribution and the SemGroup Contribution, effective as of the date of the Contribution Closing.

For the avoidance of doubt, no Party shall be obligated to amend the Unanimous Shareholder Agreement in any manner which it determines in its sole discretion would adversely impact its legal, commercial, financial or other interests.

5.8 Initial Approved Annual Budget

Following execution of this Agreement, the Parties shall in good faith work cooperatively to develop the Initial Approved Annual Budget and the Initial Approved Business Plan prior to the Closing Time. If the Parties cannot agree on the final versions thereof by the Closing Time, the budget and business plan attached as Schedule “I” will, together, be deemed to be the Initial Approved Annual Budget for purposes of the Unanimous Shareholder Agreement, and expenditures made by the Corporation in accordance therewith will be deemed to be Budgeted Expenditures; provided, however, until a replacement Initial Approved Annual Budget is approved by Extraordinary Resolution, the Corporation shall not be permitted to make any Capital Calls for such Budgeted Expenditures (other than Compliance Expenditures and Emergency Expenditures in accordance with the terms of the Unanimous Shareholder Agreement).

Subject to the other provisions of this Article 10 and such other limitations set out elsewhere in the Agreement, from and after the Contribution Closing, SemGroup shall indemnify and as a separate covenant, save the Corporation and the KKR Indemnitees harmless from and against all Losses suffered or incurred by any of them to the extent it is a result of or arising directly or indirectly from, out of, with respect to or in connection with any of the following:

(a) the implementation, completion, effect or any other aspect of the Required Transactions;

(b) the failure to make any withholdings on or with respect to any payments made by SemCAMS to SemGroup Corporation or interest expenses of SemGroup Corporation allocated to SemCAMS;

(c) the failure of the Corporation to withhold and remit on a timely basis sufficient amount under Part XIII of the Tax Act in respect of the SemGroup Contribution; or

(d) a breach or non-fulfillment of any agreement, term or covenant on the part of SemGroup made or to be observed or performed under this Agreement or any other agreement or document delivered pursuant hereto.

10.2 Indemnity by KKR

Subject to the other provisions of this Article 10 and such other limitations set out elsewhere in the Agreement, from and after the Contribution Closing, KKR shall indemnify and as a separate covenant, save the Corporation and the SemGroup Indemnitees harmless from and against all Losses suffered or incurred by any of them to the extent it is a result of or arising directly or indirectly from, out of, with respect to or in connection with any of the following:

(a) any warranties or representations made on the part of KKR in this Agreement being untrue; or

(b) a breach or non-fulfillment of any agreement, term or covenant on the part of KKR made or to be observed or performed under this Agreement or any other agreement or document delivered pursuant hereto.

Each Party will act as the trustee to its Representatives and other related indemnified Persons to the extent indemnified under this Agreement and accepts this trust and will hold and enforce the covenants herein on behalf of such Representatives and other related indemnified Persons.

- 75 -

10.4 Limitation of Liability

(a) 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.

(b) 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

- 76 -

Corporation agree and confirm that, notwithstanding any provisions of this Agreement, it will take commercially reasonable steps required by law to mitigate such Losses upon and after becoming aware of any event which would reasonably be expected to give rise to any such Losses, including if a Claim may be reduced by any recovery under or pursuant to any insurance coverage (and Purchaser will provide prompt notice to the insurer of applicable Losses that would apply towards satisfaction of such retention amount), taking commercially reasonable steps to enforce such recovery. For certainty, the commercially reasonable efforts of each of KKR and the Corporation pursuant to this Section 10.4(b) shall not include any efforts which, in its reasonable opinion, will materially adversely impact its business.

10.5 Exclusive Remedies

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

(i) 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);

(ii) 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

(iii) 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

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

(i) 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;

(ii) 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

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

- 77 -

10.6 Notice of Claim

(a) 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.

(b) 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.

10.7 Defence of Third Party Claims

(a) 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).

- 78 -

(b) 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.

(c) 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:

(i) 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

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

in which case the Indemnifying Party shall be bound by the results obtained by the Indemnified Party with respect to such Third Party Claim but shall have the right to participate in the negotiations, settlement or defence of such Third Party Claim and to retain counsel to act on its behalf and at its expense.

(d) 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.

(e) 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.

10.8 Settlement of Third Party Claims

Whether or not the Indemnifying Party assumes control of the negotiation, settlement or defence of any Third Party Claim pursuant to Section 10.7, the Indemnified Party shall not settle or pay any Third Party Claim without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, delayed or conditioned. The Indemnified Party and the Indemnifying Party shall consult and cooperate fully with each other on a timely basis with respect to Third Party Claims, and shall keep each other fully advised with respect thereto (including supplying copies of all relevant documentation promptly as it becomes available). The Indemnified Party shall make available to the Indemnifying Party or its Representatives, on a timely basis, all documents, records and other materials in the possession of the Indemnified Party which are reasonably required by the Indemnifying Party for its use in connection herewith, all at the cost and expense of the Indemnifying Party.

- 79 -

10.9 Reductions and Subrogation

(a) 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.

(b) 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.

(c) 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.

10.10 Payment and Interest

All amounts to be paid by an Indemnifying Party under this Article 10 will bear interest at a rate per annum equal to the Interest Rate, calculated and payable monthly, both before and after judgment, with interest on overdue interest at the same rate, from the date that the Indemnified Party gave notice of a Claim to the date of payment by the Indemnifying Party to the Indemnified Party.

10.11 No Double Recovery

An Indemnified Party shall not be entitled to double recovery for any Losses even though the Losses may have resulted from the breach of more than one of the representations, warranties, indemnities and covenants made or given by the Indemnifying Party in this Agreement.

- 80 -

10.12 Net Benefit

No Indemnifying Party shall be liable under this Section 10.12 in respect of any Losses suffered by any Indemnified Person to the extent there are any offsetting savings by or net financial benefits to such Indemnified Person arising from such Losses or the facts, matters, events or circumstances giving rise to such Losses. Without limiting the generality of the foregoing, in calculating the amount of any Losses indemnifiable hereunder, there shall be deducted an amount equal to the amount of the Tax deduction or Tax credit, as the case may be, multiplied by 5%.

10.13 Tax Gross Up

If any indemnity payment hereunder is subject to Tax, the Indemnity Payment shall be increased as may be necessary so that the relevant Indemnified Party will receive a net amount (after deducting such Taxes) equal to the amount otherwise payable under this Article 10.

10.14 Treatment of Indemnification Payments

To the fullest extent permitted under Applicable Laws, for all purposes (including tax purposes), the Parties shall treat any indemnification payment made under this Article 10 by KKR or SemGroup to the Corporation in respect of a misrepresentation or breach of representation or warranty as an adjustment to the purchase price paid by the Corporation in exchange for the KKR Contribution or the SemGroup Contribution, respectively. For greater certainty, the foregoing shall not result in any adjustment in the respective equity interests of shareholders in the Corporation or the number of shares issued to KKR or SemGroup in exchange for the KKR Contribution or the SemGroup Contribution, respectively.
