SEMGROUP CORPORATION
SEVERANCE AGREEMENT

THIS AGREEMENT dated as of the ____ day of _________, 20___ (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.

(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

2

--------------------------------------------------------------------------------

(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.

of the Exchange Act), other than an Affiliate of SemGroup or any employee
benefit plan (or any related trust) sponsored or maintained by SemGroup or any
of its Affiliates (a “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 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

3

--------------------------------------------------------------------------------

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.

1.17    “Code” means the Internal Revenue Code of 1986, as amended.

1.18    “Competitive Business” means, as of any date, any individual or entity

the gathering, transportation, storage, distribution, blending and/or marketing

commencing on or after Executive’s Termination Date, more than 5% of the gross
revenue of SemGroup, and, in either case, which is located (x) anywhere in the
United States, or (y) anywhere outside of the United States where SemGroup is
then engaged in, or proposes as of the Termination Date to engage in to the
knowledge of the Executive, any of such activities.

engaged, or (ii) any information obtained by SemGroup or any of its Affiliates

Notwithstanding the foregoing, “Confidential and Proprietary Information” shall
not include: (i) information that is or becomes generally known to the public

basis from a third party other than SemGroup or any Affiliate, which third party

Information” shall include the execution of this Agreement by the Executive and
the terms and conditions contained herein.

impairment of Executive where he: (a) is unable to engage in any substantial

employment with SemGroup and/or its Affiliates during the Post-Change Period due

first actual knowledge of such act or omission; and

(iii)    Unless SemGroup or the Employer fails to cure such act or omission
within the 30 day period after receiving the Notice of Termination.

(c)    No act or omission shall constitute grounds for “Good Reason”, if
Executive has consented in writing to such act or omission in a document that
makes specific reference to this Section.

1.26    “including” means including without limitation.

1.27    “IRS” means the Internal Revenue Service of the United States of
America.

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

1.29    “Notice of Termination” means a written notice of a Separation from

(a) the specific termination provision in this Agreement relied on by the party
giving such notice, (b) in reasonable detail the specific facts and

units, deferred stock or similar awards.

6

--------------------------------------------------------------------------------

(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

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 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.

1.40    “Severance Period” see Section 2.1(c).

1.41    “Stock Options” means stock options, stock appreciation rights or
similar awards.

1.42    “Subsidiary” means a corporation, trade or business, if it and SemGroup
are members of a controlled group of corporations as defined in Code Section
414(b) or under common control as defined under Code Section 414(c); the
standard of control under Code Sections 414(b) and 414(c) shall be deemed to be
“at least 80%” and all determinations shall be made in accordance with Code
Section 409A and the applicable guidance thereunder.

1.43    “Surviving Corporation” means the parent corporation resulting from a
Reorganization Transaction or, if securities representing at least 50% of the
aggregate voting power of all Voting Securities

7

--------------------------------------------------------------------------------

of a corporation affected by a Change in Control, which is not a Reorganization
Transaction, are directly or indirectly owned by another corporation, such other
corporation.

1.44    “Target Annual Bonus” means, as of any date, the amount equal to the
product of Executive’s Base Salary determined as of such date multiplied by the
percentage of such Base Salary to which Executive would have been entitled
immediately prior to such date under any Annual Bonus arrangement for the fiscal
year for which the Annual Bonus is awarded if the performance goals established
pursuant to such Annual Bonus were achieved at the 100% level as of the end of
the fiscal year; provided, however, that if Executive’s Annual Bonus is

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

(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)    Equity Awards. All of Executive’s equity awards then outstanding shall
only vest and payout in accordance with the applicable award agreements for such
equity awards, including, but not limited to, Stock Options, Restricted Shares,
Restricted Units and Performance 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

9

--------------------------------------------------------------------------------

less than, and on the same terms as those provided to peer executive officers
and directors of the Employer.

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)    Equity Awards. All of Executive’s equity awards then outstanding shall
only vest and payout in accordance with the applicable award agreements for such
equity awards, including, but not limited to, Stock Options, Restricted Shares,
Restricted Units and Performance 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.

(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.

10

--------------------------------------------------------------------------------

(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.

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.

11

--------------------------------------------------------------------------------

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, Restricted Units and Performance 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 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 set-off, 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. 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 a SemGroup Party
under any clawback policy which a SemGroup Party may adopt from time to time,
including, without limitation, any policy which a SemGroup 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 SemGroup Party’s
common stock may be listed. The Executive agrees to promptly return any such
incentive-based compensation which a SemGroup Party determines it is required to
recover from the Executive under any such clawback policy. Time is of the
essence in the performance by the SemGroup Parties of their respective
obligations under this Agreement.

12

--------------------------------------------------------------------------------

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 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. Pursuant to Section 7 of the Defend Trade Secrets Act of 2016
(which added 18 U.S.C. § 1833(b) to the United States Code), Executive
acknowledges that Executive shall not have criminal or civil liability under any
federal or state trade secret law for the disclosure of a trade secret that
(a) is made (i) in confidence to a federal, state, or local government official,
either directly or indirectly, or to an attorney and (ii) solely for the purpose
of reporting or investigating a suspected violation of law; or (b) is made in a
complaint or other document filed in a lawsuit or other proceeding, if such
filing is made under seal.  Further, if Executive files a lawsuit for
retaliation by Employer for reporting a suspected violation of law, Executive
may disclose the trade secret to the attorney of Executive and use the trade
secret information in the court proceeding, if Executive files any document
containing the trade secret under seal and does not disclose the trade secret,
except pursuant to court order.  Nothing in this Agreement is intended to
conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade
secrets that are expressly allowed by such Section.

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)

13

--------------------------------------------------------------------------------

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;

(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

14

--------------------------------------------------------------------------------

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

15

--------------------------------------------------------------------------------

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 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 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.

16

--------------------------------------------------------------------------------

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.

(b)    When a Claim has been filed properly, it shall be evaluated and the
Claimant shall be notified of the approval or the denial of the Claim within 30
days after the receipt of such Claim. A Claimant shall be given a written notice
in which the Claimant shall be advised as to whether the Claim is granted or
denied, in whole or in part. If a Claim is denied, in whole or in part, the
notice shall contain: (i) the specific reasons for the denial, (ii) references
to pertinent provisions of this Agreement on which the denial is based, (iii) a
description of any additional material or information necessary to perfect the
Claim and an explanation of why such material or information is necessary, (iv)
the Claimant’s right to seek review of the denial and a description of the
procedures for such review, and (v) a statement regarding Claimant’s right to
bring a civil action under Section 502(a) of ERISA following an adverse decision
on appeal.

17

--------------------------------------------------------------------------------

6.2    Review of Claim Denial. If a Claim is denied, in whole or in part, or if
a Claim is neither approved nor denied within the 30-day period specified
Section 6.1(b), the Claimant (or his authorized representative) shall have the
right at any time to: (a) request that SemGroup (or such other person as shall
be designated in writing by SemGroup) review the denial or the failure to
approve or deny the Claim, (b) review pertinent documents, and (c) submit issues
and comments in writing. Within 30 days after such a request is received,
SemGroup shall complete its review and give the Claimant written notice of its
decision. Upon request and without charge, the Claimant will be provided
reasonable access to and copies of all documents, records and other information
relevant to the claim. SemGroup shall include in its notice to Claimant: (i) the
specific reasons for its decision, (ii) references to provisions of this
Agreement on which its decision is based, (iii) a statement that the Claimant is
entitled to receive, upon request and free of charge, reasonable access to and
copies of all documents, records and other information relevant to the claim,
and (iv) a statement regarding the Claimant’s right to bring a civil action
under ERISA Section 502(a) within 180 days of receipt of notice of denial on
appeal.

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.

7.2    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. 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
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.

7.3    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.

7.4    Non-Alienation of Benefits. 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.

18

--------------------------------------------------------------------------------

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
Agreement intend that this Agreement meet the requirements of Code Section 409A
and recognize that it may be necessary to modify this Agreement to reflect
guidance under Code Section 409A issued by the Internal Revenue Service.

7.7    Notices. All notices and other communications under this Agreement shall
be in writing and delivered by hand, by nationally-recognized delivery service

the addressee.

7.8    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.

7.9    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.

7.10    Governing Law. This Agreement shall be interpreted and construed in
accordance with the laws of the State of Delaware, without regard to its choice
of law principles, except to the extent such law is preempted by ERISA or other
applicable federal law.

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

7.12    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.

NOW THEREFORE, in consideration for receiving benefits and severance under the
Severance Agreement and in consideration of the representations, covenants and
mutual promises set forth in this Agreement, the parties agree as follows:

the Executive’s termination of employment with the Company including, but not
limited to, any and all claims or demands pursuant to Title VII of the Civil
Rights Act of 1964 as amended by the Civil Rights Act of 1991, which prohibits
discrimination in employment based on race, color, national origin, religion or
sex; the Civil Rights Act of 1866, 42 U.S.C. §2000e, et seq., 42 U.S.C. §1981,

was to avoid payment of such benefits or payments, and that, as a result of his

behalf of the Company or by any person employed by or representing the Company,
except for the written provisions and promises contained in this Agreement.

3.    Damages. The parties agree that damages incurred as a result of a breach
of this Agreement will be difficult to measure. It is, therefore, further agreed
that, in addition to any other remedies, equitable relief will be available in
the case of a breach of this Agreement. It is also agreed that, in the event
Executive files a claim against the Company with respect to a claim released by
Executive herein (other than a proceeding before the EEOC), the Company may
withhold, retain, or require reimbursement of all or any portion of the benefits
and severance payments under the Severance Agreement until such claim is
withdrawn by Executive.

the following:

(a)    Executive has read this Agreement, and understands its legal and binding
effect. Executive is acting voluntarily and of Executive’s own free will in
executing this Agreement.

this Agreement will not be effective until after the seven-day period has
expired.

5.    Severability. If all or any part of this Agreement is declared by any
court or governmental authority to be unlawful or invalid, such unlawfulness or
invalidity shall not invalidate any other portion of this Agreement. Any section
or a part of a section declared to be unlawful or invalid shall, if possible, be
construed in a manner which will give effect to the terms of the section to the
fullest extent possible while remaining lawful and valid.

6.    Amendment. This Agreement shall not be altered, amended, or modified
except by written instrument executed by the Company and the Executive. A waiver
of any portion of this Agreement shall not be deemed a waiver of any other
portion of this Agreement.

7.    Counterparts. This Agreement may be executed in several counterparts, each
of which shall be deemed to be an original, but all of which together will
constitute one and the same instrument.

8.    Headings. The headings of this Agreement are not part of the provisions
hereof and shall not have any force or effect.

9.    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.
