 SEMGROUP CORPORATION 

SEVERANCE AGREEMENT 

THIS AGREEMENT dated as of the      day of June, 2010 (the “Agreement Date”) is made by and between
SemGroup Corporation, a corporation incorporated under the laws of the State of Delaware (“SemGroup”, together with its subsidiaries, affiliates and successors thereto), and
                             (“Executive”). 

RECITALS 

The Board of Directors of SemGroup has determined that it is in the best interests of SemGroup and its stockholders to encourage and
motivate the Executive to devote his full attention to the performance of his assigned duties without the distraction of concerns regarding his involuntary or constructive termination of employment for the reasons specified in this Agreement. The
Executive is employed by SemGroup or a Subsidiary and may from time to time be employed by one or more Subsidiaries. SemGroup and its Subsidiaries believe that it is in the best interest of the Executive, their customers, the communities they serve,
and the stockholders of SemGroup to provide financial assistance through severance payments and other benefits to Executive if Executive is involuntarily or constructively terminated for the reasons specified in this Agreement. This Agreement is
intended to accomplish these objectives.

Executive’s Base Salary that is accrued but not yet paid as of the Termination Date, other than amounts Executive has elected to defer.

Annual Bonus, any accrued but unpaid vacation, and any other amounts and benefits which are then due to be paid or provided to Executive by SemGroup, but have not yet been paid or provided (as applicable), provided no payments will be accelerated if
such acceleration would violate Code Section 409A. 
 1.4 “Affiliate” means any Person (including a
Subsidiary) that directly or indirectly, through one or more intermediaries, controls, or is controlled by or is under common control with SemGroup. For purposes of this definition the term “control” with respect to any Person means the

ending on the second anniversary of the Agreement Date. Notwithstanding anything herein to the contrary, with respect to a Post-Change Period, the Agreement Term shall end at the end of the Severance Period (as defined in Section 2.1(c)) if
applicable, or if there is no such Severance Period, the earliest of the following: (a) the second anniversary of the Change Date, or (b) the Termination Date; provided that: (i) the obligations, if any, of SemGroup to make payments
under this Agreement due to a Separation from Service which occurred during the Agreement Term shall continue beyond the Agreement Term until all such obligations are fully satisfied, and (ii) the obligations of Executive under this Agreement

Section 1.21. 
 1.7 “Annual Bonus” means the opportunity to receive payment of a cash annual incentive.

 (a) Executive’s conviction of or plea of nolo contendere to a felony or
other crime involving fraud, dishonesty or moral turpitude;

(iii) any act or omission with respect to which a determination could properly have been made by the Board that Executive
had satisfied the applicable standard of conduct for indemnification or reimbursement under SemGroup’s certificate of incorporation, by-laws, Board resolutions, any applicable indemnification agreement, or applicable law, in each case as in
effect at the time of such act or omission; or 
 (iv) during a Post-Change Period, failure to meet performance
goals, objectives or measures following good faith efforts to meet such goals, objectives or measures; and 
 further provided that, for
purposes of clauses (b) through (e) if an act, or a failure to act, which was done, or omitted to be done, by Executive in good faith and with a reasonable belief, after reasonable investigation, that Executive’s act, or failure to
act, was in the best interests of SemGroup, the Subsidiary or an Affiliate or was required by applicable law or administrative regulation, such breach shall not constitute Cause if, within 10 business days after Executive is given written notice of
such breach that specifically refers to this Section, Executive cures such breach to the fullest extent that it is curable. With respect to the above definition of “cause”, no act or conduct by Executive will constitute “cause”
if Executive acted: (i) in accordance with the instructions or advice of counsel representing SemGroup or if there was a conflict such that Executive could not consult with counsel representing SemGroup, other qualified counsel, or (ii) as
required by legal process. 
 1.14 “Cause Determination” see Section 2.3(b)(iv). 

1.15 “Change Date” means the date on which a Change in Control first occurs during the Agreement Term.

“Related Party”), becomes the Beneficial Owner of 30% or more of the common stock of SemGroup or of Voting Securities representing 30% or more of the combined voting 

 

 3 

 
power of all Voting Securities of SemGroup, except that no Change in Control shall be deemed to have occurred solely by reason of such beneficial ownership by a Person with respect to which both
more than 70% of the common stock of such Person and Voting Securities representing more than 70% of the combined voting power of the Voting Securities of such Person are then owned, directly or indirectly, by the persons who were the direct or
indirect owners of the common stock and Voting Securities of SemGroup immediately before such acquisition, in substantially the same proportions as their ownership, immediately before such acquisition, of the common stock and Voting Securities of
SemGroup, as the case may be; or 
 (b) SemGroup Incumbent Directors (determined using the Agreement Date as the
baseline date) cease for any reason to constitute at least a majority of the directors of SemGroup then serving; or 

(c) consummation of a merger, reorganization, recapitalization, consolidation, or similar transaction (any of the
foregoing, a “Reorganization Transaction”), other than a Reorganization Transaction that results in the Persons who were the direct or indirect owners of the outstanding common stock and Voting Securities of SemGroup immediately before
such Reorganization Transaction becoming, immediately after the consummation of such Reorganization Transaction, the direct or indirect owners, of both at least 60% of the then-outstanding common stock of the Surviving Corporation and Voting
Securities representing at least 60% of the combined voting power of the then-outstanding Voting Securities of the Surviving Corporation, in substantially the same respective proportions as such Persons’ ownership of the common stock and Voting
Securities of SemGroup immediately before such Reorganization Transaction; or 
 (d) approval by the stockholders
of SemGroup of a plan or agreement for the sale or other disposition of all or substantially all of the consolidated assets of SemGroup or a plan of complete liquidation of SemGroup, other than any such transaction that would result in: (i) a
Related Party owning or acquiring more than 50% of the assets owned by SemGroup immediately prior to the transaction, or (ii) the Persons who were the direct or indirect owners of the outstanding common stock and Voting Securities of SemGroup
immediately before such transaction becoming, immediately after the consummation of such transaction, the direct or indirect owners, of more than 50% of the assets owned by SemGroup immediately prior to the transaction. 

Notwithstanding the occurrence of any of the foregoing events, a Change in Control shall not occur with respect to Executive if, in
advance of such event, Executive agrees in writing that such event shall not constitute a Change in Control. Upon the Board’s determination that a sale or other disposition of all or substantially all of the consolidated assets of SemGroup or a
plan of complete liquidation of SemGroup that was approved by stockholders, as described in Section 1.16(d), will not occur, a Change in Control shall be deemed not to have occurred from such date of determination forward, and this Agreement
shall continue in effect as if no Change in Control had occurred except to the extent termination requiring payments under this Agreement occurs prior to such Board determination.

1.28 “Notice of Consideration” see Section 2.3(b)(ii).

 1.35 “Section” means,
unless the context otherwise requires, a section of this Agreement. 
 1.36 “SemGroup” see the introductory
paragraph of this Agreement. 
 1.37 “SemGroup Incumbent Directors” means, determined as of any date by
reference to any baseline date: 
 (a) the members of the Board on the date of such determination who have been
members of the Board since such baseline date, and 
 (b) the members of the Board on the date of such
determination who were appointed or elected after such baseline date and whose election, or nomination for election by stockholders of SemGroup or the Surviving Corporation, as applicable, was approved by a vote or written consent of two-thirds of
the directors comprising the SemGroup Incumbent Directors on the date of such vote or written consent, but excluding each such member whose initial assumption of office was in connection with (i) an actual or threatened election contest,
including a consent solicitation, relating to the election or removal of one or more members of the Board, (ii) a “tender offer” (as such term is used in Section 14(d) of the Exchange Act), or (iii) a proposed Reorganization
Transaction. 
 1.38 “SemGroup Parties” means SemGroup and Executive’s Employer. 

1.39 “Separation from Service” means an Executive’s termination or deemed termination from employment with SemGroup
and its Subsidiaries. For purposes of determining whether a Separation from Service has occurred, the employment relationship is treated as continuing intact while the Executive is on military leave, sick leave or other bona fide leave of absence if
the period of such leave does not exceed six months, or if longer, so long as the Executive retains a right to reemployment with his employer under an applicable statute or by contract. For this purpose, a leave of absence constitutes a bona fide
leave of absence only if there is a reasonable expectation that the Executive will return to perform services for his employer. If the period of leave exceeds six months and the Executive does not retain a right to reemployment under an applicable
statute or by contract, the employment relationship will be 
  

 8 

 
deemed to terminate on the first date immediately following such six month period. Notwithstanding the foregoing, if a leave of absence is due to any medically determinable physical or mental
impairment that can be expected to result in death or can be expected to last for a continuous period of not less than six months, and such impairment causes the Executive to be unable to perform the duties of the Executive’s position of
employment or any substantially similar position of employment, a 29 month period of absence shall be substituted for such six month period. For purposes of this Agreement, a Separation from Service occurs at the date as of which the facts and
circumstances indicate either that, after such date: (A) the Executive and SemGroup reasonably anticipate the Executive will perform no further services for SemGroup and its Subsidiaries (whether as an employee or an independent contractor), or
(B) that the level of bona fide services the Executive will perform for SemGroup and its Affiliates (whether as an employee or independent contractor) will permanently decrease to no more than 20% of the average level of bona fide services
performed over the immediately preceding 36 month period or, if the Executive has been providing services to SemGroup and its Subsidiaries for less than 36 months, the full period over which the Executive has rendered services, whether as an
employee or independent contractor. The determination of whether a Separation from Service has occurred shall be governed by the provisions of Treasury Regulation § 1.409A-1, as amended, taking into account the objective facts and circumstances
with respect to the level of bona fide services performed by the Executive after a certain date.

 ARTICLE II 

 SEMGROUP’S OBLIGATIONS UPON SEPARATION FROM SERVICE 

2.1 If By Executive for Good Reason or By an Employer Other Than for Cause, Disability, Death or Disqualifying Disaggregation During
the Post-Change Period. If Executive has a Separation from Service for Good Reason or there is an Employer-initiated Separation from Service of the Executive for any reason other than Cause, Disability, Death or a Disqualifying Disaggregation
during the Post-Change Period, then in addition to payment of all Accrued Obligations, which shall be payable no later than 10 business days after the Termination Date, SemGroup’s and the Employer’s sole obligations to Executive under this
Article II shall be as follows: 
 (a) Severance Payments. Executive shall be paid a lump-sum cash amount
equal to the sum of the following, on the first business day following six months after Executive’s Separation from Service: 

(i) Annual Bonus for Fiscal Year Prior to Year of Termination. If the Termination Date occurs after the end of a
fiscal year but before the Annual Bonus with respect to such fiscal year is fully paid out, the Annual Bonus for such prior fiscal year shall be paid to Executive, but the payment shall be reduced (but not below zero) by the amount of any Annual
Bonus previously paid to Executive with respect to such prior fiscal year; and 
  

 10 

 (ii) Multiple of Salary and Bonus. An amount equal to two
(2) times the sum of: (A) Base Salary plus (B) the Target Annual Bonus, each determined as of the Termination Date; provided, however, that any reduction in Executive’s Base Salary or Target Annual Bonus that would qualify as
Good Reason shall be disregarded for this purpose. 
 (b) Stock Incentive Awards. All of Executive’s
Stock Options and Restricted Shares then outstanding shall only vest and payout in accordance with the applicable award agreements for such Stock Options and Restricted Shares. 

(c) Continuation of Welfare Benefits. During the lesser of the period during which Executive or a qualifying
beneficiary (as defined in Section 607 of ERISA) has in effect an election for post-termination continuation coverage or conversion rights to welfare benefits under applicable law, including Section 4980 of the Code (“COBRA”), or
the period ending on the 18-month anniversary of the Termination Date (“Severance Period”), Executive (or, if applicable, the qualifying beneficiary) shall be entitled to such coverage at an out-of-pocket premium cost that does not exceed
the out-of-pocket premium cost applicable to similarly situated active employees (and their eligible dependents); provided, however, that if Executive is eligible to retiree benefits provided under any welfare benefit plan, program, policy, practice
or procedure of the SemGroup Parties, Executive shall be entitled to receive such retiree benefits in lieu of the COBRA coverage provided by this Section 2.1(c). 

(d) Outplacement. Executive shall be reimbursed for reasonable fees and costs for outplacement services incurred by
Executive within six months after the Separation from Service, promptly upon presentation of reasonable documentation of such fees and costs, subject to a maximum of $10,000. All requests of Executive for reimbursement must be submitted to SemGroup
within one year of Separation from Service and SemGroup shall make the reimbursement of reasonable requests no later than 30 days after such request, but in all events within 15 months of Separation from Service. 

(e) Directors’ and Officers’ Liability Insurance. For a period of six years after the Termination Date
(or for any known longer applicable statute of limitations period), the Executive shall be entitled to coverage under a directors’ and officers’ liability insurance policy in an amount no less than, and on the same terms as those provided
to peer executive officers and directors of the Employer. 
  

 11 

 2.2 If By an Employer Other Than for Cause, Disability or Death Prior to the Post-Change
Period. If there is an Employer-initiated Separation from Service of the Executive for any reason other than Cause, Disability or Death prior to the Post-Change Period, then in addition to payment of all Accrued Obligations, which shall be
payable no later than 30 business days after the Termination Date, SemGroup’s and the Employer’s sole obligations to Executive under this Article II shall be as follows: 

(a) Severance Payments. Executive shall be paid a lump-sum cash amount equal to the sum of the following, on the
first business day following six months after Executive’s Separation from Service: 
 (i) Annual Bonus
for Fiscal Year Prior to Year of Termination. If the Termination Date occurs after the end of a fiscal year but before the Annual Bonus with respect to such fiscal year is fully paid out, the Annual Bonus for such prior fiscal year shall be paid
to Executive, but the payment shall be reduced (but not below zero) by the amount of any Annual Bonus previously paid to Executive with respect to such prior fiscal year; and 

(ii) Multiple of Salary and Bonus. An amount equal to one (1) times the sum of: (A) Base Salary plus
(B) the Target Annual Bonus, each determined as of the Termination Date. 
 (b) Stock Incentive
Awards. All of Executive’s Stock Options and Restricted Shares then outstanding shall only vest and payout in accordance with the applicable award agreements for such Stock Options and Restricted Shares. 

(c) Outplacement. Executive shall be reimbursed for reasonable fees and costs for outplacement services incurred by
Executive within six months after the Separation from Service, promptly upon presentation of reasonable documentation of such fees and costs, subject to a maximum of $10,000. All requests of Executive for reimbursement must be submitted to SemGroup
within one year of Separation from Service and SemGroup shall make the reimbursement of reasonable requests no later than 30 days after such request, but in all events within 15 months of Separation from Service. 

(d) Directors’ and Officers’ Liability Insurance. For a period of six years after the Termination Date
(or for any known longer applicable statute of limitations period), the Executive shall be entitled to coverage under a directors’ and officers’ liability insurance policy in an amount no less than, and on the same terms as those provided
to peer executive officers and directors of the Employer. 
 2.3 If by the Employer for Cause. 

(a) Termination for Cause. If the Executive has a Separation from Service for Cause, the 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. 
  

 12 

 (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, the 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 SemGroup 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 the SemGroup Parties on the other hand, the 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 the SemGroup Parties have satisfied all applicable substantive and
procedural requirements of this Section. 
  

 13 

 2.4 If by an Executive Other Than for Good Reason. If Executive has a Separation from
Service initiated by the Executive other than for Good Reason, Disability or death, the sole obligation of the SemGroup Parties 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. 
 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 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. 
 2.6 Waiver and Release. Notwithstanding anything herein to the contrary, in the event that
Executive’s employment terminates pursuant to Section 2.1 or 2.2, no SemGroup 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 Affiliates, in substantially the same form as attached hereto as Exhibit A, or as otherwise mutually acceptable. 

2.7 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, (a) no SemGroup 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 shall be forfeited as of the date of the breach, (d) Executive shall reimburse a SemGroup 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 2.7, “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. 

2.8 Code Section 280G Cutback. Notwithstanding any provision of this Agreement to the contrary, if any amount or benefit to
be paid under Section 2.1 of this Agreement would be an “excess parachute payment” (within the meaning of Section 280G of the Code, or any successor provision thereto) but for the application of this sentence, then the payment to
be paid or provided under this Agreement will be reduced to the minimum extent necessary (but in no event to less than zero) so that no portion of any such payment, as so reduced, constitutes an excess parachute payment. Whether requested by
Executive or the Company, the determination of whether any reduction in such payment or benefit to be provided under this Agreement or 

 

 14 

 
otherwise is required pursuant to the preceding sentence will be made at the expense of the Company by the Company’s independent accountants. The fact that Executive’s right to payment
or benefit may be reduced by reason of the limitations contained in this Section 2.8 will not of itself limit or otherwise affect any rights Executive has other than pursuant to this Agreement. In the event that any payment or benefit intended
to be provided under this Agreement is required to be reduced pursuant to this Section 2.8, the Company will reduce Executive’s payment and/or benefit, to the extent required, in the following order: (i) the lump sum payment described
in Section 2.1(a), (ii) the health continuation benefits set forth in Section 2.1(c), and (iii) the outplacement benefit described in Section 2.1(d). 

ARTICLE III 

NO SET-OFF OR MITIGATION 

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 setoff, counterclaim, recoupment, or other claim, right or action that any SemGroup 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 SemGroup Party shall have the right to deduct any amounts outstanding on any loans or other extensions of credit to Executive from a SemGroup Party from Executive’s
payments and other benefits (if any) provided for under this Agreement. Time is of the essence in the performance by the SemGroup Parties of their respective obligations under this Agreement. 

3.2 No Mitigation. Executive shall not have any duty to mitigate the amounts payable by any SemGroup 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. 

ARTICLE IV 

RESTRICTIVE COVENANTS 

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 1.19). 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 

 

 15 

 
a court or governmental agency, in each case provided 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. 

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, Executive agrees that without the written consent of SemGroup Executive shall not at any time, directly or indirectly, in any capacity: 

(a) engage or participate in, become 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, 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 to terminate his relationship with SemGroup or an Affiliate; 
  

 16 

 (b) solicit the employment or engagement as a consultant or adviser, of any
employee of SemGroup or an Affiliate (other than by SemGroup or its Affiliates), or cause or attempt to cause any Person to do any of the foregoing; 

(c) establish (or take preliminary steps to establish) a business with, or cause or attempt to cause others to establish
(or take preliminary steps to establish) a business with, any employee of SemGroup or an Affiliate, if such business is or will be a Competitive Business; or 

(d) solicit the purchase or sale of goods, services or combination of goods and services from the established customers of
SemGroup or an Affiliate. For the purpose of this provision, “established customers” shall be deemed to include any entity or person which has been a customer or supplier of SemGroup or an Affiliate within twelve (12) months of the
date of cessation of Executive’s employment with SemGroup or an Affiliate. 
 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 and, if subject to copyright, shall be considered a “work made for hire” within the meaning of the Copyright Act of 1976, as amended. If and to the extent that any such Work Product is not a “work made for
hire” within the meaning of the Copyright Act of 1976, as amended, 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. 
  

 17 

 (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 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 law, Executive will promptly inform SemGroup of any such obligation
prior to participating in any such proceedings. 
  

 18 

 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 to be issued by a court of competent jurisdiction, to restrain any breach, or threatened breach, of any provision of this Agreement
without the necessity of posting a bond or other security therefor, and Executive hereby waives any right to assert any claim or defense that SemGroup has an adequate remedy at law for any such breach. 

(b) If a court determines that any covenant included in this Article IV is unenforceable in whole or in part because of
such covenant’s duration or geographical or other scope, 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. 

(c) 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 2.7, 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
ERISA) after the Termination Date if Executive has materially breached any of Executive’s obligations under this Agreement. 
  

 19 

 ARTICLE V 

NON-EXCLUSIVITY OF RIGHTS 

5.1 Waiver of Certain Other Rights. To the extent that Executive shall have received severance payments or other severance
benefits under any other plan, program, policy, practice or procedure or agreement of any SemGroup Party prior to receiving severance payments or other severance benefits pursuant to Article II, the severance payments or other severance benefits
under such other plan, program, policy, practice or procedure or agreement shall reduce (but not below zero) the corresponding severance payments or other benefits to which Executive shall be entitled under Article II. To the extent that Executive
accepts payments made pursuant to Article II, he shall be deemed to have waived his right to receive a corresponding amount of future severance payments or other severance benefits under any other plan, program, policy, practice or procedure or
agreement of any SemGroup Party. 
 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 SemGroup 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 SemGroup 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. 

ARTICLE VI 

CLAIMS PROCEDURE 

6.1 Filing a Claim. 

(a) Each individual eligible for benefits under this Agreement (“Claimant”) may submit his application for
benefits (“Claim”) to SemGroup (or to such other person as may be designated by SemGroup) in writing in such form as is provided or approved by SemGroup. A Claimant shall have no right to seek review of a denial of benefits, or to bring
any action in any court to enforce a Claim, prior to his filing a Claim and exhausting his rights to review under Sections 6.1 and 6.2.

 ARTICLE VII 

MISCELLANEOUS 

7.1 No Assignability. This Agreement is personal to Executive and without the prior written consent of SemGroup shall not be
assignable by Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by Executive’s legal representatives.

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. Any successor to the business or assets of SemGroup (or any
Employer) which assumes or agrees to perform this Agreement by operation of law, contract, or otherwise shall be jointly and severally liable with SemGroup (or the Employer) under this Agreement as if such successor were SemGroup (or the Employer).
If Executive’s employment is transferred from SemGroup to a Subsidiary, or from a Subsidiary to SemGroup or another

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. 
 7.5 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. 

7.6 Amendments. This Agreement shall not be amended or modified except by written instrument executed by SemGroup and Executive;
provided however that notwithstanding the terms of this Agreement to the contrary, the terms of this Agreement shall be administered in such a way to comply with Code Section 409A as reasonably deemed appropriate by SemGroup; provided further
however that notwithstanding anything to the contrary herein, SemGroup shall have the unilateral right to modify or amend this Agreement as it reasonably deems appropriate related to compliance with Code Section 409A. The parties to this

 EXHIBIT 10.14 

SemManagement LLC

THIS RETENTION AWARD AGREEMENT (this “Agreement”) is made effective as of
                    , 2010 (the “Date of Grant”) by and among SemGroup Corporation, a Delaware corporation
(“SemGroup”), SemManagement LLC, a Delaware limited liability company (the “Company”), and                     
(the “Employee”). 
 R E C I T A L S: 

WHEREAS, SemGroup, the Company’s parent, has adopted the SemGroup Corporation Equity Incentive Plan (the “Plan”),
which Plan, as it may be amended from time to time, is incorporated herein by reference and made a part of this Agreement. Capitalized terms not otherwise defined herein shall have the same meanings as ascribed to them in the Plan; and 

WHEREAS, the Company has recently emerged from bankruptcy with new management and a new and changing ownership structure at a time of
general economic uncertainty; and 
 WHEREAS, the various changes in the Company and economic uncertainties have resulted in the
departure of key employees and the consideration by other key employees of employment opportunities outside the Company; and 

WHEREAS, the Company believes that it is in the best interests of the Company, its affiliates and SemGroup stockholders to provide the
Employee with an incentive to continue his or her employment with the Company and to motivate the Employee to maximize the value of the Company and its affiliates for SemGroup stockholders; and 

WHEREAS, SemGroup and the Company have determined that it would be in the best interests of SemGroup, the Company, its affiliates and
SemGroup stockholders to grant the Retention Award described below pursuant to the Plan in accordance with the Plan and the terms set forth herein. 

NOW THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties agree as follows: 

1. Retention Award. Subject to the terms and conditions of the Plan and this Agreement, the Company hereby grants to the Employee
a Retention Award (“the Award”) of $                    , which shall vest and be payable in accordance with Section 2
hereof. 

 2. Vesting and Payment of Award. 

(a) Vesting Schedule. Subject to the Employee’s continued Service through the vesting date, the Award shall fully vest on
that date which is 18 months following the Date of Grant. 
 (b) Termination Due to Death. If the Employee’s Service
terminates due to the Employee’s death prior to payment of the Award, the Award shall vest on the Employee’s date of death. 

(c) Involuntary Termination of Service Other Than for Cause. If the Employee’s Service is involuntarily terminated for any
reason other than for Cause, the Award shall vest upon such termination. For this purpose, “Cause” shall mean, with respect to the Employee, one or more of the following: (i) the plea of guilty or nolo contendere to, or
conviction of, the commission of a felony offense (ii) any act of willful fraud, dishonesty or moral turpitude that causes a material harm to SemGroup, the Company or any Subsidiary or Affiliate, (iii) gross negligence or gross misconduct
with respect to SemGroup, the Company or any Subsidiary or Affiliate, (iv) willful and deliberate failure to perform his or her employment duties in any material respect, or (v) breach of a material written employment policy of SemGroup,
the Company or any Subsidiary or Affiliate, provided, however, that in the case of an Employee who has an employment agreement with SemGroup, the Company or any Subsidiary or Affiliate in which “Cause” is defined,
“Cause” shall be determined in accordance with such definition. 
 (d) Other Termination of Service. If the
Employee’s Service terminates prior to payment of the Award for any reason other than as described in Section 2(b) or Section 2(c) above, then the Award shall be forfeited by the Employee without any consideration.

 (e) Payment of Award. The Award, net of amounts withheld pursuant to this subsection and Section 7 below,
shall be paid upon vesting to the Employee or the Employee’s beneficiary or legal representative in cash or Shares, at the discretion of the Company, within 74 days following vesting, Shares that become payable under this Agreement will be paid
either (i) by book entry in the stock records of the SemGroup recording ownership by the Employee or the Employee’s beneficiary of, or (ii) by the delivery to the Employee, or the Employee’s beneficiary or legal representative,
of one or more certificates (or other indicia of ownership) representing, Shares equal in number to the dollar amount of the Award divided by the Fair Market Value of a Share at the close of business on the day the Award vests, less the number of
Shares having a Fair Market Value, as of the date the withholding tax obligation arises, equal to the minimum statutory withholding requirements. No fractional shares will be issued, but shall instead be paid out in equivalent cash value.

  

 2 

 3. No Right to Continued Service. The granting of the Award evidenced hereby and this
Agreement shall impose no obligation on SemGroup, the Company or any Affiliate or Subsidiary to continue the Service of the Employee and shall not lessen or affect any right that SemGroup, the Company or any Affiliate or Subsidiary may have to
terminate the Service of such Employee. 
 4. Certificates. In the event the Award is paid in Shares, a certificate or
certificates representing Shares shall be issued by SemGroup and shall be registered in the name of the Employee on the stock transfer books of SemGroup promptly following issuance. Each certificate representing the Shares shall bear such legends as
SemGroup deems advisable pursuant to Section 6 below. 
 5. Rights as a Stockholder. The Employee shall have
none of the rights of a Stockholder of SemGroup unless and until Shares are issued. 
 6. Securities Laws; Legend on
Certificates. The issuance and delivery of Shares shall comply with all applicable requirements of law, including (without limitation) the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, state securities
laws and regulations, and the regulations of any stock exchange or other securities market on which SemGroup’s securities may then be traded. If SemGroup deems it necessary to ensure that the issuance of Shares under the Plan is not required to
be registered under any applicable securities laws, each Employee to whom such Shares would be issued shall deliver to the Company an agreement or certificate containing such representations, warranties and covenants as SemGroup may request which
satisfies such requirements. The certificates representing the Shares shall be subject to such stop transfer orders and other restrictions as the Committee may deem reasonably advisable, and the Committee may cause a legend or legends to be put on
any such certificates to make appropriate reference to such restrictions. 
 7. Withholding. The Employee agrees that
(a) he or she will pay to the Company or any applicable Affiliate or Subsidiary, as the case may be, or make arrangements satisfactory to the Company or such Affiliate or Subsidiary regarding the payment of any foreign, federal, state, or local
taxes of any kind required by law to be withheld by the Company or such Affiliate or Subsidiary with respect to the Award, and (b) the Company, or such Affiliate or Subsidiary, shall, to the extent permitted by law, have the right to deduct
from any payments of any kind otherwise due to the Employee any foreign, federal, state, or local taxes of any kind required by law to be withheld with respect to any Shares issued. 

8. Notices. Any notification required by the terms of this Agreement shall be given in writing and shall be deemed effective upon
personal delivery or within three (3) days of deposit with the United States Postal Service (or in the case of a non-U.S. Employee, the foreign postal service of the country in which the Employee resides), by registered or certified mail, with
postage and fees prepaid. A notice shall be addressed to SemGroup or the Company, Attention: General Counsel, at the Company’s principal executive office and to the Employee at the address that he or she most recently provided to the Company.

 9. Entire Agreement. This Agreement and the Plan constitute the entire contract
between the parties hereto with regard to the subject matter hereof. They supersede any other agreements, representations or understandings (whether oral or written and whether express or implied) which relate to the subject matter hereof.

 10. Waiver. No waiver of any breach or condition of this Agreement shall be deemed to be a waiver of any other or
subsequent breach or condition whether of like or different nature. 
 11. Employee Undertaking. The Employee agrees to
take whatever additional action and execute whatever additional documents the Company may deem necessary or advisable to carry out or effect one or more of the obligations or restrictions imposed on either the Employee or the Shares pursuant to this
Agreement. 
 12. Designation of Beneficiary. An Employee’s beneficiary for receipt of any payment made under this
Agreement in the event of the Employee’s death shall be the person(s) designated as the Employee’s beneficiary(ies) for life insurance benefits under the Company’s fully Company-paid life insurance benefits plan unless the Employee
designates a different beneficiary on a form prescribed by the Company. If no beneficiary is designated, upon the death of the Employee, payment shall be made to the Employee’s estate. 

13. Successors and Assigns. The provisions of this Agreement shall inure to the benefit of, and be binding upon, SemGroup, the
Company and their respective successors and assigns and upon the Employee, the Employee’s assigns and the legal representatives, heirs and legatees of the Employee’s estate, whether or not any such person shall have become a party to this
Agreement and agreed in writing to be joined herein and be bound by the terms hereof. 
 14. Choice of Law; Jurisdiction;
Waiver of Jury Trial. This Agreement shall be governed by the laws of the State of Delaware, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of the Plan to the substantive law
of another jurisdiction. 
 SUBJECT TO THE TERMS OF THIS AGREEMENT, THE PARTIES AGREE THAT ANY AND ALL ACTIONS ARISING UNDER OR IN RESPECT OF
THIS AGREEMENT SHALL BE LITIGATED IN THE FEDERAL OR STATE COURTS IN DELAWARE. BY EXECUTING AND DELIVERING THIS AGREEMENT, EACH PARTY IRREVOCABLY SUBMITS TO THE PERSONAL JURISDICTION OF SUCH COURTS FOR ITSELF, HIMSELF OR HERSELF AND IN RESPECT OF
ITS, HIS OR HER PROPERTY WITH RESPECT TO SUCH ACTION. EACH PARTY AGREES THAT VENUE WOULD BE PROPER 
  

 4 

 
IN ANY OF SUCH COURTS, AND HEREBY WAIVES ANY OBJECTION THAT ANY SUCH COURT IS AN IMPROPER OR INCONVENIENT FORUM FOR THE RESOLUTION OF ANY SUCH ACTION. 

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT
OF OR RELATING TO THIS AGREEMENT. 
 15. Shares Subject to Plan. By entering into this Agreement the Employee agrees
and acknowledges that the Employee has received and read a copy of the Plan. Shares, if any, issued pursuant to this Agreement are subject to the Plan. In the event of a conflict between any term or provision contained herein and a term or provision
of the Plan, the applicable terms and provisions of the Plan will govern and prevail. The Employee has had the opportunity to retain counsel, and has read carefully, and understands, the provisions of the Plan and this Agreement. 

16. Amendment. SemGroup and the Company may amend or alter this Agreement and the Award granted hereunder at any time;
provided, that, subject to Article 11 and Article 12 of the Plan, no such amendment or alteration shall be made without the consent of the Employee if such action would materially diminish any of the rights of the
Employee under this Agreement or with respect to the Award. 
 17. No Section 83(b) Election. The Employee agrees
not to make an election with the Internal Revenue Service under Section 83(b) of the Code with respect to the Shares. 

18. Severability. The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or
otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable. 
 19.
Signature in Counterparts. This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 

20. No Guarantees Regarding Tax Treatment. Employees (or their beneficiaries) shall be responsible for all taxes with respect to
the Shares. Neither SemGroup nor the Company makes any guarantees regarding the tax treatment of the Shares. Neither SemGroup nor the Company has any obligation to take any action to prevent the assessment of any tax under Section 409A of the
Code or Section 457A of the Code or otherwise and none of SemGroup, the Company, any Affiliate or Subsidiary, or any of their respective employees or representatives shall have any liability to an Employee with respect thereto. 

 

 5 

 21. Confidentiality. By signing this Agreement, the Employee agrees that he or she
will not disclose its terms or the Employee’s participation in the Company’s retention program to any person or entity at any time unless ordered to do so by a court of competent jurisdiction or otherwise as required by law. This
Section 21 is in addition to and does not supersede any other confidentiality agreement the Employee has signed or to which the Employee is otherwise a party or any confidentiality policy to which Employee is subject as an employee of
the Company. This Section 21 survives Employee’s termination of employment and the termination of this Agreement. If the Employee violates this Section 21, Employee will forfeit any and all right to an Award and, if any
Award has previously been paid to the Employee, the Employee shall be obligated to return the full amount or value of such Award to the Company together with any earnings thereon. Further, if such violation occurs during Employee’s employment
by the Company, the Company reserves the right to terminate the Employee’s employment and to treat such termination as a termination for Cause under this Agreement as well as under any other agreement or plan of the Company. 

22. Compliance with Section 409A. The Company intends that the Award be structured in compliance with, or to satisfy an
exemption from, Section 409A of the Code and all regulations, guidance, compliance programs and other interpretative authority thereunder (“Section 409A”), such that there are no adverse tax consequences, interest, or penalties under
Section 409A as a result of the granting, vesting or payment of the Award. In the event the Award is subject to Section 409A, the Company may, in its sole discretion, take the actions described in Section 11.1 of the Plan.
Notwithstanding any contrary provision in the Plan or this Agreement, any payment of nonqualified deferred compensation (within the meaning of Section 409A) that is otherwise required to be made under this Agreement to a “specified
employee” (as defined under Section 409A) as a result of his or her separation from service (other than a payment that is not subject to Section 409A) shall be delayed for the first six (6) months following such separation from
service (or, if earlier, the date of death of the specified employee) and shall instead be paid on the date that immediately follows the end of such six (6) month period. A termination of Service shall not be deemed to have occurred for
