2.3    If by an Employer for Cause.

(a)    Termination for Cause. If the Executive has a Separation from Service for Cause, SemGroup Parties’ sole obligation to Executive under this ARTICLE II shall be to pay Executive a lump-sum cash amount equal to all Accrued Obligations determined as of the Termination Date, and any other minimum amounts required by applicable employment standards legislation.

(b)    Change in Control: Procedural Requirements for Termination for Cause. For any Separation from Service for Cause during any part of a Post-Change Period, SemGroup Parties shall strictly observe each of the following substantive and procedural provisions:

(i)    The Board shall call a meeting for the stated purpose of determining whether Executive’s acts or omissions satisfy the requirements of the definition of “Cause” and, if so, whether to terminate Executive’s employment for Cause.

(ii)    Not less than 15 days prior to the date of such meeting, the Board shall provide or cause to be provided Executive and each member of the Board written notice (a “Notice of Consideration”) of: (A) a detailed description of the acts or omissions alleged to constitute Cause, (B) the date of such meeting of the Board, and (C) Executive’s rights under clauses (iii) and (iv) below.

(iii)    Executive shall have the opportunity to present to the Board a written response to the Notice of Consideration, but shall not have the right to appear in person or by counsel before the Board.

(iv)    Executive’s employment may be terminated for Cause only if: (A) the acts or omissions specified in the Notice of Consideration did in fact occur and such actions or omissions do constitute Cause as defined in this Agreement, (B) the Board, by affirmative vote of a simple majority of its members, makes a specific determination to such effect and to the effect that Executive’s employment should be terminated for Cause (“Cause Determination”), and (C) SemGroup thereafter provides Executive with a Notice of Termination that specifies in specific detail the basis of such Separation from Service for Cause and which Notice shall be consistent with the reasons set forth in the Notice of Consideration.

(v)    In the event that the existence of Cause shall become an issue in any action or proceeding between Executive, on the one hand, and any one or more of the Company Parties, on the other hand, the Cause Determination shall be final and binding on all parties, except as provided in Section 2.3(c) below.

Nothing in this Section 2.3(b) shall preclude the Board, by majority vote, from suspending Executive from his duties, with pay, at any time.

(c)    Change in Control: Standard of Review. In the event that the existence of Cause during a Post-Change Period shall become an issue in any action or proceeding between Executive, on the one hand, and any one or more of SemGroup Parties on the other hand, SemGroup Parties, as applicable, shall, notwithstanding the Cause Determination, have the burden of establishing that the actions or omissions specified in the Notice of Consideration did in fact occur and do constitute Cause and that SemGroup Parties have satisfied all applicable substantive and procedural requirements of this Section.

2.4    If Voluntarily by the Executive Other Than for Good Reason. If the Executive has a Separation from Service initiated by the Executive other than for Good Reason, the Executive may voluntarily terminate this Agreement and the employment of the Executive by providing SemGroup Parties with sixty (60) days' prior written notice of the same. After receiving such notice from the Executive, SemGroup Parties may either require the Executive to continue to perform the Executive's duties or dismiss the Executive at any time by paying the Executive the amounts which otherwise would have been payable to the Executive throughout the remainder of the sixty (60) day notice period by the Executive to the Company Parties, and any other amount required by applicable employment standards legislation.

2.5    If by Death or Disability. If Executive dies or if Executive has a Separation from Service by reason of Executive’s Disability, the Company Parties’ sole obligation to Executive under this ARTICLE II shall be to pay Executive a lump-sum cash amount equal to all Accrued Obligations determined as of the Termination Date and any other amounts or entitlements required by applicable employment standards legislation, except that if the termination of the Executive's employment would impair the Executive's ability to receive long term disability benefits in whole or in part the Executive shall, in lieu of termination, be placed on an unpaid leave of absence, it being understood that the Executive shall not be entitled to re-employment by SemGroup Parties after such leave of absence or when the Executive ceases to be in receipt of such benefits. The Executive agrees that if SemGroup

Parties terminate the Executive for Disability, this Agreement will have been frustrated and, in any event, that accommodating a Disability would impose undue hardship on SemGroup Parties.

2.6    SemCAMS Disaggregation. In the event there is a SemCAMS Disaggregation and, for certainty, SemCAMS or its successor or any of their affiliates does not assume all of SemGroup or its Affiliates’ obligations under this Agreement then, provided Executive does not continue employment (other than in circumstance where Cause exists) with SemGroup or its Affiliates, or SemCAMS or its successor or any of their affiliates for one (1) year following such SemCAMS Disaggregation, Executive shall receive those amounts and entitlements set out in Section 2.2.

2.7    Waiver and Release. Notwithstanding anything herein to the contrary, and subject to compliance with applicable employment standards legislation, in the event that Executive’s employment terminates pursuant to Section 2.1 or 2.2, no Company Party shall have any obligation to Executive under Sections 2.1(a)-(e) or 2.2(a)-(d), as the case may be, unless and until Executive executes and delivers to SemGroup within 60 days after Separation from Service a release and waiver of SemGroup, the Employer and their Affiliates, in a form acceptable to SemGroup.

2.8    Breach of Covenants. If a court determines that Executive has breached any non- competition, non-solicitation, non-disparagement, confidential information or intellectual property covenant entered into at any time between Executive (on the one hand) and SemGroup, the Employer, or any Affiliate (on the other hand), including the Restrictive Covenants in ARTICLE IV, then, except for any minimum amounts or entitlements required by applicable employment standards legislation, and to the extent permitted by applicable law, (a) no Company Party shall have any obligation to pay or provide any severance or benefits under ARTICLE II (b) all of Executive’s unexercised Stock Options shall terminate as of the date of the breach, (c) all of Executive’s unvested Restricted Shares, Restricted Units and Performance Shares shall be forfeited as of the date of the breach, (d) Executive shall reimburse a Company Party for any amount already paid under ARTICLE II, and (e) Executive shall repay to SemGroup an amount equal to the aggregate “spread” (as defined below) on all Stock Options, if any, exercised in the one year period prior to the first date on which Executive breached any such covenant (“Breach Date”). For purposes of this Section 2.8, “spread” in respect of any Stock Option shall mean the product of the number of shares as to which such Stock Option has been exercised during the one year period prior to the Breach Date multiplied by the difference between the closing price of the Class A common stock on the exercise date (or if the Class A common stock did not trade on the exercise date on the principal stock exchange on which the Class A common stock is then listed

or if not so listed in the over-the-counter market, the most recent date on which the Class A common stock did so trade) and the exercise price of the Stock Options. The Executive agrees that the foregoing provisions represent a bona fide estimate of damage that SemGroup will suffer if the Executive breaches the Executive’s obligations as set out above, and are not and are not to be construed as a penalty clause.

3.1    No Set-off by SemGroup. Executive’s right to receive when due the payments and other benefits provided for under this Agreement is absolute, unconditional and subject to no set-off, counterclaim, recoupment, or other claim, right or action that any Company Party may have against Executive or others, except as expressly provided in this Section or as specifically otherwise provided in this Agreement. Notwithstanding the prior sentence, any Company Party shall have the right to deduct any amounts outstanding on any loans or other extensions of credit to Executive from a Company Party from Executive’s payments and other benefits (if any) provided for under this Agreement. Notwithstanding any provision of this Agreement to the contrary, Executive acknowledges that any incentive-based compensation paid to the Executive under this Agreement may be subject to recovery by SemGroup Party under any clawback policy which a Company Party may adopt from time to time, including, without limitation, any policy which a Company Party may be required to adopt under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the rules and regulations of the SEC thereunder or the requirements of any national securities exchange on which a Company Party’s common stock may be listed. The Executive agrees to promptly return any such incentive-based compensation which a Company Party determines it is required to recover from the Executive under any such clawback policy. Time is of the essence in the performance by SemGroup Parties of their respective obligations under this Agreement. Notwithstanding any of the foregoing, the Executive shall not receive less than the minimum amounts and other entitlements required by applicable employment standards legislation.

3.2    No Mitigation. Executive shall not have any duty to mitigate the amounts payable by any Company Party under this Agreement by seeking new employment or self-employment following termination. Except as specifically otherwise provided in this Agreement, all amounts payable pursuant to this Agreement shall be paid without reduction regardless of any amounts of salary, compensation or other amounts which may be paid or payable to Executive as the result of Executive’s employment by another employer or self-employment.

4.1    Confidential and Proprietary Information. The Executive acknowledges that in the course of performing services for SemGroup and its Affiliates, Executive may create (alone or with others), learn of, have access to, or receive Confidential and Proprietary Information (as defined in Section 1.18). The Executive recognizes that all such Confidential and Proprietary Information is the sole and exclusive property of SemGroup and its Affiliates or of third parties to which SemGroup or an Affiliate owes a duty of confidentiality, that it is SemGroup’s policy to safeguard and keep confidential all such Confidential and Proprietary Information, and that disclosure of Confidential and Proprietary Information to an unauthorized third party would cause irreparable damage to SemGroup and its Affiliates. Executive agrees that, except as required by the duties of Executive’s employment with SemGroup or any of its Affiliates and except in connection with enforcing Executive’s rights under this Agreement or if compelled by a court or governmental agency, in each case provided, to the extent permitted by applicable law, that prior written notice is given to SemGroup, Executive will not, without the written consent of SemGroup, willfully disseminate or otherwise disclose, directly or indirectly, any Confidential and Proprietary Information disclosed to Executive or otherwise obtained by Executive during his employment with SemGroup or its Affiliates, and will take all necessary precautions to prevent disclosure, to any unauthorized individual or entity (whether or not such individual or entity is employed or engaged by, or is otherwise affiliated with, SemGroup or any Affiliate), and will use the Confidential and Proprietary Information solely for the benefit of SemGroup and its Affiliates and will not use the Confidential and Proprietary Information for the benefit of any other Person nor permit its use for the benefit of Executive. These obligations shall continue during and after the termination of Executive’s employment for any reason and for so long as the Confidential and Proprietary Information remains Confidential and Proprietary Information. In addition, the Executive shall deliver all documents, notes, drawings and analyses containing or reflecting such Confidential and Proprietary Information to SemGroup or its Affiliates at any time upon request of SemGroup or its Affiliates, and in any event shall deliver all such documents, notes, drawings and analyses to SemGroup or its Affiliates upon the termination of the Executive’s employment regardless of whether or not expressly requested to do so at the time employment or engagement pursuant to this Agreement ceases. The Executive may, however, use or disclose:

(a)    Confidential and Proprietary Information (except personal information) that (i) is or becomes public, other than through a breach of this Agreement; or (ii) is known to the Executive

prior to employment or engagement by SemGroup and with respect to which the Executive does not have any obligation of confidentiality; or

(b)    Confidential and Proprietary Information that is required to be disclosed, or the disclosure of which to regulators is protected, by law, whether under an order of a court or government tribunal, statutory provision or other legal process, provided that, where such disclosure is required of the Executive, the Executive informs the Company of such requirement as soon as the Executive becomes aware of the requirement and in sufficient time to allow SemGroup to take such steps as are lawfully available to SemGroup to avoid or limit such disclosure by the Executive.

4.2    Non-Competition. During the period beginning on the Agreement Date and ending on the first anniversary of the Termination Date, regardless of the reason for Executive’s Separation from Service, whether with or without cause or by resignation, the Executive shall not, directly or indirectly, within Canada:

(a)    engage or participate in, becoming employed by, serve as a director of, or render advisory or consulting or other services in connection with, any Competitive Business; provided, however, that after Executive’s Separation from Service, this Section 4.2 shall not preclude Executive from: (i) being an employee of, or consultant to, any business unit of a Competitive Business if: (A) such business unit does not qualify as a Competitive Business in its own right, and (B) Executive does not have any direct or indirect involvement in, or responsibility for, any operations of such Competitive Business that cause it to qualify as a Competitive Business, or (ii) with the approval of SemGroup, being a consultant to, an advisor to, a director of, or an employee of a Competitive Business; or

(b)    make or retain any financial investment, whether in the form of equity or debt, or own any interest, in any Competitive Business. Nothing in this subsection (b) shall, however, restrict Executive from making an investment in any Competitive Business if such investment does not: (i) represent more than 1% of the aggregate market value of the outstanding capital stock or debt (as applicable) of such Competitive Business, (ii) give Executive any right or ability, directly or indirectly, to control or influence the policy decisions or management of such Competitive Business, or (iii) create a conflict of interest between Executive’s duties to SemGroup and its Affiliates or under this Agreement and his interest in such investment.

4.3    Non-Solicitation. During the period beginning on the Agreement Date and ending on the first anniversary of the Termination Date, regardless of the reason for Executive’s Separation from Service, whether with or without Cause or by resignation, Executive shall not, directly or indirectly:

(a)    other than in connection with the good-faith performance of his duties as an officer of SemGroup or its Affiliates, cause or attempt to cause any employee, director or consultant of SemGroup or an Affiliate (or who was an employee, director or consultant of SemGroup or an Affiliate within the prior 12 months to the Termination Date) to terminate his relationship with SemGroup or an Affiliate;

(b)    solicit the employment or engagement as a consultant or adviser, of any employee of SemGroup or an Affiliate (or who was an employee, consultant or adviser of SemGroup or an Affiliate within the prior 12 months to the Termination Date), other than by SemGroup or its Affiliates, or cause or attempt to cause any Person to do any of the foregoing;

(c)    solicit, approach, contact, call upon or canvass (or attempt to do any of the foregoing), in connection with any undertaking that is in whole or in part a Competitive Business, any customer, client or distributor of SemGroup or an Affiliate to whom, at any time within the 12 month period prior to the Termination Date, the Executive in the course of performing the Executive’s duties had direct and personal contact if the purpose or effect or intended effect of such solicitation would be/is to reduce the actual or potential business of SemGroup to/from/with such customer, client or distributor.

4.4    Intellectual Property.

(a)    During the period of Executive’s employment with SemGroup or any Affiliate, and thereafter upon SemGroup’s request, regardless of the reason for Executive’s Separation from Service, Executive shall disclose immediately to SemGroup all Work Product that: (i) relates to the business of SemGroup or any Affiliate or any customer or supplier to SemGroup or an Affiliate or any of the products or services being developed, manufactured, sold or otherwise provided by SemGroup or an Affiliate or that may be used in relation therewith; or (ii) results from tasks or projects assigned to Executive by SemGroup or an Affiliate; or (iii) results from the use of the premises or personal property (whether tangible or intangible) owned, leased

or contracted for by SemGroup or an Affiliate. Executive agrees that any Work Product shall be the property of SemGroup. Executive hereby assigns, and agrees to assign, to SemGroup all right, title and interest in and to the Work Product and all copies thereof, and all copyrights, patent rights, trademark rights, trade secret rights and all other proprietary and intellectual property rights in the Work Product, without further consideration, free from any claim, lien for balance due, or rights of retention thereto on the part of Executive.

(b)    Notwithstanding the foregoing, SemGroup agrees and acknowledges that the provisions of Section 4.4(a) relating to ownership and disclosure of Work Product do not apply to any inventions or other subject matter for which no equipment, supplies, facility, or trade secret information of SemGroup or an Affiliate was used and that are developed entirely on Executive’s own time, unless: (i) the invention or other subject matter relates: (A) to the business of SemGroup or an Affiliate, or (B) to the actual or demonstrably anticipated research or development of SemGroup or any Affiliate, or (ii) the invention or other subject matter results from any work performed by Executive for SemGroup or any Affiliate.

(c)    Executive agrees that, upon disclosure of Work Product to SemGroup, Executive will, during his employment by SemGroup or an Affiliate and at any time thereafter, at the request and cost of SemGroup, execute all such documents and perform all such acts as SemGroup or an Affiliate (or their respective duly authorized agents) may reasonably require: (i) to apply for, obtain and vest in the name of SemGroup alone (unless SemGroup otherwise directs) letters patent, copyrights or other intellectual property protection in any country throughout the world, and when so obtained or vested to renew and restore the same; and (ii) to prosecute or defend any opposition proceedings in respect of such applications and any opposition proceedings or petitions or applications for revocation of such letters patent, copyright or other intellectual property protection, or otherwise in respect of the Work Product.

(d)    In the event that SemGroup is unable, after reasonable effort, to secure Executive’s execution of such documents as provided in Section 4.4(c), whether because of Executive’s physical or mental incapacity or for any other reason whatsoever, Executive hereby irrevocably designates and appoints SemGroup and its duly authorized officers and agents as his agent and attorney-in-fact, to act for and on his behalf to execute and file any such application or applications and to do all other lawfully permitted acts to further the prosecution, issuance

and protection of letters patent, copyright and other intellectual property protection with the same legal force and effect as if personally executed by Executive.

4.5    Non-Disparagement.

(a)    Executive agrees not to make, or cause to be made, any statement, observation or opinion, or communicate any information (whether oral or written, directly or indirectly) that: (i) accuses or implies that SemGroup and/or any of its Affiliates, together with their respective present or former officers, directors, partners, stockholders, employees and agents, and each of their predecessors, successors and assigns, engaged in any wrongful, unlawful or improper conduct, whether relating to Executive’s employment (or the termination thereof), the business or operations of SemGroup, or otherwise; or (ii) disparages, impugns or in any way reflects adversely upon the business or reputation of SemGroup and/or any of its Affiliates, together with their respective present or former officers, directors, partners, stockholders, employees and agents, and each of their predecessors, successors and assigns.

(b)    SemGroup agrees not to authorize any statement, observation or opinion, or communicate any information (whether oral or written, direct or indirect) that: (i) accuses or implies that Executive engaged in any wrongful, unlawful or improper conduct relating to Executive’s employment or termination thereof with SemGroup, or otherwise; or (ii) disparages, impugns or in any way reflects adversely upon the reputation of Executive.

(c)    Notwithstanding anything contained herein to the contrary, nothing herein shall be deemed to preclude or limit (i) Executive or SemGroup from providing truthful testimony or information pursuant to subpoena, court order or other similar legal or regulatory process, provided, that to the extent permitted by applicable law, Executive will promptly inform SemGroup of any such obligation prior to participating in any such proceedings or (ii) Executive from (A) filing a charge or complaint with any Government Agency, (B) communicating with any Government Agency or otherwise participating in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to SemGroup, or (C) receiving an award for information provided to any Government Agency.

4.6    Reasonableness of Restrictive Covenants.

(a)    Executive acknowledges that the covenants contained in this Agreement are reasonable in the scope of the activities restricted, the geographic area covered by the restrictions, and the duration of the restrictions, and that such covenants are reasonably necessary to protect SemGroup’s legitimate interests in its Confidential and Proprietary Information, its proprietary work, and in its relationships with its employees, customers, suppliers and agents.

(b)    SemGroup has, and Executive has had an opportunity to, consult with their respective legal counsel and to be advised concerning the reasonableness and propriety of such covenants. Executive acknowledges that his observance of the covenants contained herein will not deprive Executive of the ability to earn a livelihood or to support his dependents.

(c)    Executive understands he is bound by the terms of this ARTICLE IV, whether or not he receives severance payments under this Agreement or otherwise.

4.7    Right to Injunction: Survival of Undertakings.

(a)    In recognition of the confidential nature of the Confidential and Proprietary Information, and in recognition of the necessity of the limited restrictions imposed by this Agreement, Executive and SemGroup agree that it would be impossible to measure solely in money the damages which SemGroup would suffer if Executive were to breach any of his obligations hereunder. Executive acknowledges that any breach of any provision of this Agreement would irreparably injure SemGroup. Accordingly, Executive agrees that if he breaches any of the provisions of this Agreement, SemGroup shall be entitled, in addition to any other remedies to which SemGroup may be entitled under this Agreement or otherwise, to an injunction, without having to prove damages, to be issued by a court of competent jurisdiction, to restrain any breach, or threatened breach, of any provision of this Agreement by the Executive, or by any or all of the Executive's partners, employers, employees, servants, agents, representatives and any other Persons directly or indirectly acting for, or on behalf of, or with, the Executive, without the necessity of posting a bond or other security therefor. Executive hereby waives any right to assert any claim or defense that SemGroup has an adequate remedy at law for any such breach and agrees that SemGroup shall be entitled to all of its costs and expenses incurred in obtaining such relief. If any covenant or provision of this ARTICLE IV is determined to be void or unenforceable in whole or in part, for any reason,

it shall be deemed not to affect or impair the validity of any other covenant or provision of this Agreement, which shall remain in full force and effect. Further, to the extent any covenant or provision of this ARTICLE IV is determined by a court of competent jurisdiction to be void or unenforceable in whole or in part because of such covenant’s duration or geographical or other scope, then such court shall have the power to modify the duration or scope of such provision, as the case may be, so as to cause such covenant as so modified to be enforceable.

(b)    All of the provisions of this Agreement shall survive any Separation from Service of Executive, without regard to the reasons for such termination. Notwithstanding Section 2.8, in addition to any other rights it may have, neither SemGroup nor any Affiliate shall have any obligation to pay or provide severance or other benefits (except as may be required under applicable law) after the Termination Date if Executive has materially breached any of Executive’s obligations under this Agreement.

5.1    Waiver of Certain Other Rights. Executive agrees that, for as long as this Agreement is in force, the severance payments and severance benefits set out in ARTICLE II, or otherwise within this Agreement, shall govern all of Executive’s entitlements on separation of employment from Employer or SemGroup or its Affiliates, howsoever caused, and that except as set out in this Agreement or otherwise required by applicable employment standards legislation, Executive has no further right to any severance payment, severance benefits, notice of termination, or pay in lieu of notice of termination pursuant to the common law or any other agreement.

5.2    Other Rights. Except as expressly provided in Section 5.1 and as provided in the Recitals to this Agreement, this Agreement shall not prevent or limit Executive’s continuing or future participation in any benefit, bonus, incentive or other plan, program, policy, practice or procedure provided by a Company Party and for which Executive may qualify, nor shall this Agreement limit or otherwise affect such rights as Executive may have under any other agreements with a Company Party. Amounts that are vested benefits or that Executive is otherwise entitled to receive under any plan, program, policy, practice or procedure and any other payment or benefit required by law at or after the Termination Date shall be payable in accordance with such plan, program, policy, practice or procedure or applicable law except as expressly modified by this Agreement.

5.3    No Right to Continued Employment. Nothing in this Agreement shall guarantee the right of Executive to continue in employment, and SemGroup and the Employer retain the right to terminate Executive’s employment at any time for any reason or for no reason.

6.1    No Assignability. This Agreement shall be binding on the Executive and their respective heirs, administrators and executors. The Executive shall not assign or transfer, whether absolutely, by way of security or otherwise, all or any part of the Employee’s rights or obligations under this Agreement without the prior consent of SemGroup, which may be arbitrarily withheld.

6.2    Successors. This Agreement shall inure to the benefit of and be binding upon SemGroup and its successors and assigns. SemGroup will require any successor (whether direct or indirect, by

purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of SemGroup (or the Employer during any Post-Change Period) to assume expressly and agree to perform this Agreement in the same manner and to the same extent that SemGroup (or, if applicable, the Employer) would be required to perform it if no such succession had taken place. If Executive’s employment is transferred from SemGroup to a Subsidiary, or from a Subsidiary to SemGroup or another Subsidiary, the rights and obligations of the Employer (determined prior to such transfer) shall automatically become the rights and obligations of the Employer (determined immediately following such transfer), without requiring the consent of Executive.

6.3    Payments to Beneficiary. If Executive dies before receiving amounts to which Executive is entitled under this Agreement, such amounts shall be paid in a lump sum to one or more beneficiaries designated in writing by Executive (each, a “Beneficiary”). An Executive’s Beneficiary for receipt of any payment made under this Agreement in the event of Executive’s death shall be the person(s) designated as the Executive’s Beneficiary(ies) for life insurance benefits under SemGroup’s fully company-paid life insurance benefits plan unless Executive designates a different Beneficiary on the form prescribed by SemGroup. If no Beneficiary is designated, Executive’s estate shall be his Beneficiary.

6.4    Non-Alienation of Benefits. Except where required by applicable law, benefits payable under this Agreement shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, charge, garnishment, execution or levy of any kind, either voluntary or involuntary, before actually being received by Executive, and any such attempt to dispose of any right to benefits payable under this Agreement shall be void.

6.5    Severability. If any one or more Articles, Sections or other portions of this Agreement are declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not serve to invalidate any Article, Section or other portion not so declared to be unlawful or invalid. Any Article, Section or other portion so declared to be unlawful or invalid shall be construed so as to effectuate the terms of such Article, Section or other portion to the fullest extent possible while remaining lawful and valid.

6.6    Amendments. No amendment of this Agreement shall be effective unless made in writing and signed by the parties.

6.7    Notices. All notices and other communications under this Agreement shall be in writing and delivered by hand, by nationally-recognized delivery service that promises overnight delivery, or by first-class registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

to Executive at his most recent home address on file with SemGroup.

6.8    Joint and Several Liability. In the event that the Employer incurs any obligation to Executive pursuant to this Agreement, such Employer, SemGroup and each Subsidiary, if any, of which such Employer is a subsidiary shall be jointly and severally liable with such Employer for such obligation.

6.9    Counterparts. This Agreement may be executed in 2 or more counterparts, each of which shall be deemed an original, but all of which together constitute one and the same instrument.

6.10    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the Province of Alberta and the laws of Canada applicable in that Province and shall be treated, in all respects, as an Alberta contract.

6.11    Currency. Unless otherwise provided, all dollar amounts referred to in this Agreement are in lawful money of Canada.

6.12    Captions. The captions of this Agreement are not a part of the provisions hereof and shall have no force or effect.

6.13    Rules of Construction. Reference to a specific law shall include such law, any valid regulation promulgated thereunder, and any comparable provision of any future legislation amending, supplementing or superseding such section.

6.14    Number and Gender. Wherever appropriate, the singular shall include the plural, the plural shall include the singular, and the masculine shall include the feminine.

6.15    Tax Withholding. SemGroup may withhold from any amounts payable under this Agreement or otherwise payable to Executive any Taxes SemGroup determines to be required under applicable law or regulation and may report all such amounts payable to such authority as is required by any applicable law or regulation.

6.16    Entire Agreement. This Agreement and the documents expressly referred to herein contain the entire understanding of SemGroup and Executive with respect to severance or benefits in relation to a Change in Control or Separation from Service, and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, with respect to severance or benefits in relation to a Change in Control or Separation from Service.

7.1    Acknowledgement. The Executive acknowledges that:

(a)    the Executive has had sufficient time to review the Agreement thoroughly;

(b)    the Executive has read and understands the terms of the Agreement and the obligations hereunder; and

(c)    the Executive has been given an opportunity to obtain independent legal advice concerning the interpretation and effect of the Agreement.
