notice by the Borrower pursuant to this Section 2.02(a) must be confirmed promptly by delivery to the Administrative Agent of a written Loan
Notice, appropriately completed and signed by a Responsible Officer of General Partner, in its capacity as the sole general partner of the Borrower. Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall be in a principal
amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof or in the amount of the unused Commitments of all the Lenders. Except as provided in Section 2.03(c), each Borrowing of or conversion to Base Rate Loans shall be in
a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or in the amount of the unused Commitments of all the Lenders. Each Loan Notice (whether telephonic or written) shall specify (i) whether the Borrower is
requesting a Borrowing, a conversion of Loans from one Type to the other, or a continuation of Eurodollar Rate Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day),
(iii) the principal amount of Loans to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or to which existing Loans are to be converted, and (v) if applicable, the duration of the Interest Period with respect
thereto. If the Borrower fails to specify a Type of Loan in a Loan Notice or if the Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loans shall be made as, or converted to, Base Rate Loans. Any
such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loans. If the Borrower requests a Borrowing of, conversion to, or continuation of
Eurodollar Rate Loans in any such Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month. 
 (b) Following receipt of a Loan Notice, the Administrative Agent shall promptly notify each Lender of the amount of its Applicable
Percentage of the applicable Loans, and if no timely notice of a conversion or continuation is provided by the Borrower, the Administrative Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans described in the
preceding subsection. In the case of a Borrowing, each Lender shall make the amount of its Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 1:00 p.m. on the Business
Day specified in the applicable Loan Notice. Upon satisfaction of the applicable conditions set forth in Section 4.02 (and, if such Borrowing is the initial Credit Extension, Section 4.01), the Administrative Agent shall make
all funds so received available to the Borrower in like funds as received by the Administrative Agent either by (i) crediting the account of the Borrower on the books of Wachovia Bank with the amount of such funds or (ii) wire transfer of
such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) the Administrative Agent by the Borrower; provided, however, that if, on the date the Loan Notice with respect to such Borrowing is
given by the Borrower, there are L/C Borrowings outstanding, then the proceeds of such Borrowing, first, shall be applied to the payment in full of any such L/C Borrowings, and second, shall be made available to the Borrower as
provided above. 
 (c) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted
only on the last day of an Interest Period for such Eurodollar Rate Loan. During the existence of a Default, no Loans may be requested as, converted to or continued as Eurodollar Rate Loans without the consent of the Required Lenders. 
  


					
		 	29	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (d) The Administrative Agent shall promptly notify the Borrower and the Lenders of the
interest rate applicable to any Interest Period for Eurodollar Rate Loans upon determination of such interest rate. At any time that Base Rate Loans are outstanding, the Administrative Agent shall notify the Borrower and the Lenders of any change in
Wachovia Bank’s prime rate used in determining the Base Rate promptly following the public announcement of such change. 
 (e) After giving effect to all Borrowings, all conversions of Loans from one Type to the other, and all continuations of Loans as the same Type, there shall not be more than ten Eurodollar Rate Loans outstanding at any time. 
 2.03 Letters of Credit. 
 (a) The Letter of Credit Commitment. 
 (i) Subject to the terms and conditions set forth herein: (A) the
L/C Issuer agrees, in reliance upon the agreements of the Lenders set forth in this Section 2.03, (1) from time to time on any Business Day during the period from the Closing Date until the Letter of Credit Expiration Date, to issue
Letters of Credit upon the request of the Borrower for the account of the Borrower or any Restricted Subsidiary, and to amend Letters of Credit previously issued by it, in accordance with subsection (b) below, and (2) to honor drawings
under the Letters of Credit; (B) the Lenders severally agree to participate in Letters of Credit issued for the account of the Borrower or any Restricted Subsidiary and any drawings thereunder; provided that, after taking such Letter of Credit
into account, (x) the Total Outstandings shall not exceed the Aggregate Commitments of all the Lenders, (y) the aggregate Outstanding Amount of the Loans of any Lender, plus such Lender’s Applicable Percentage of the
Outstanding Amount of all L/C Obligations, plus such Lender’s Applicable Percentage of the Outstanding Amount of all Swing Line Loans shall not exceed such Lender’s Commitment and (z) the Outstanding Amount of the L/C
Obligations shall not exceed the Letter of Credit Sublimit. Each request by the Borrower for the issuance or amendment of a Letter of Credit shall be deemed to be a representation by the Borrower that the L/C Credit Extension so requested complies
with the conditions set forth in the proviso to the preceding sentence. Within the foregoing limits, and subject to the terms and conditions hereof, the Borrower’s ability to obtain Letters of Credit shall be fully revolving, and accordingly
the Borrower may, during the foregoing period, obtain Letters of Credit for the account of the Borrower or any Restricted Subsidiary to replace Letters of Credit that have expired or that have been drawn upon and reimbursed. 
 (ii) The L/C Issuer shall not issue any Letter of Credit if the expiry date of such requested Letter of Credit would occur after the
Letter of Credit Expiration Date, unless all the Lenders have approved such expiry date. The L/C Issuer shall not be under any obligation to issue any Letter of Credit, unless (A) such Letter of Credit expires on or prior to 365 days after the
date of issuance, is in a face amount, in the aggregate with all other Letters of Credit outstanding at any one time under this clause (A), that does not to exceed the Letter of Credit Sublimit, is used to secure or assure the performance of surety
bonds, performance bonds, statutory obligations and other obligations of a like nature

incurred in the ordinary course of business of the Borrower or any of its Subsidiaries or other general corporate purposes of Borrower or any of its
Subsidiaries and is in such form as shall be acceptable to Administrative Agent and L/C Issuer in their sole and absolute discretion and (B) such Letter of Credit is in such other form, terms and purposes as shall be acceptable to
Administrative Agent and L/C Issuer in their sole and absolute discretion. 
 (iii) The L/C Issuer shall not be under any
obligation to issue any Letter of Credit if: 
 (A) any order, judgment or decree of any Governmental Authority or arbitrator
shall by its terms purport to enjoin or restrain the L/C Issuer from issuing such Letter of Credit, or any Law applicable to the L/C Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with
jurisdiction over the L/C Issuer shall prohibit, or request that the L/C Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon the L/C Issuer with respect to such Letter of
Credit any restriction, reserve or capital requirement (for which the L/C Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon the L/C Issuer any unreimbursed loss, cost or expense which was not
applicable on the Closing Date and which the L/C Issuer in good faith deems material to it; 
 (B) the issuance of such
Letter of Credit would violate one or more policies of the L/C Issuer; 
 (C) except as otherwise agreed by the
Administrative Agent and the L/C Issuer, such Letter of Credit is in an initial stated amount less than $25,000; 
 (D) such
Letter of Credit is to be denominated in a currency other than Dollars; 
 (E) such Letter of Credit contains any provisions
for automatic reinstatement of the stated amount after any drawing thereunder; or 
 (F) a default of any Lender’s
obligations to fund under Section 2.03(c) exists or any Lender is at such time a Defaulting Lender hereunder, unless the L/C Issuer has entered into satisfactory arrangements with the Borrower or such Lender to eliminate the L/C
Issuer’s risk with respect to such Lender. 
 (iv) The L/C Issuer shall not amend any Letter of Credit if the L/C Issuer
would not be permitted at such time to issue such Letter of Credit in its amended form under the terms hereof. 
 (v) The L/C
Issuer shall be under no obligation to amend any Letter of Credit if (A) the L/C Issuer would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter
of Credit does not accept the proposed amendment to such Letter of Credit. 
  


					
		 	31	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (vi) The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of
Credit issued by it and the documents associated therewith, and the L/C Issuer shall have all of the benefits and immunities (A) provided to the Administrative Agent in Article IX with respect to any acts taken or omissions suffered by
the L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and Issuer Documents pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in Article IX included
the L/C Issuer with respect to such acts or omissions, and (B) as additionally provided herein with respect to the L/C Issuer. 
 (b) Procedures for Issuance and Amendment of Letters of Credit. 
 (i) Each Letter of Credit shall be issued
or amended, as the case may be, upon the request of the Borrower for the account of the Borrower or any Restricted Subsidiary, as the case may be, delivered to the L/C Issuer (with a copy to the Administrative Agent) in the form of a Letter of
Credit Application, appropriately completed and signed by a Responsible Officer of General Partner, in its capacity as the sole general partner of the Borrower, making such request. Such Letter of Credit Application must be received by the L/C
Issuer and the Administrative Agent not later than noon at least one Business Day (or such later date and time as the Administrative Agent and the L/C Issuer may agree in a particular instance in their sole discretion) prior to the proposed issuance
date or date of amendment, as the case may be. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the L/C Issuer: (A) the proposed issuance
date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such
beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as the L/C Issuer may require. In the case of a request
for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the L/C Issuer (A) the Letter of Credit to be amended; (B) the proposed date of amendment thereof
(which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as the L/C Issuer may require. Additionally, the Borrower shall furnish to the L/C Issuer and the Administrative Agent such other
documents and information pertaining to such requested Letter of Credit issuance or amendment, including any Issuer Documents, as the L/C Issuer or the Administrative Agent may require. 
 (ii) Promptly after receipt of any Letter of Credit Application, the L/C Issuer will confirm with the Administrative Agent (by telephone
or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, the L/C Issuer will provide the Administrative Agent with a copy thereof. Unless the L/C Issuer has received written
notice from any Lender, the Administrative Agent or any Restricted Subsidiary, at least one Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions contained in
Article IV shall not then be satisfied, then, subject to the terms and conditions hereof, the L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of the Borrower or the applicable Restricted 

  


					
		 	32	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
Subsidiary, as the case may be, or enter into the applicable amendment, as the case may be, in each case in accordance with the L/C Issuer’s usual and
customary business practices. Immediately upon the issuance of such Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, severally purchase from the L/C Issuer a risk participation in all Letters of
Credit issued for the account of the Borrower or any Restricted Subsidiary and any drawings thereunder in an amount equal to the product of such Lender’s Applicable Percentage times the amount of such Letter of Credit. 
 (iii) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto
or to the beneficiary thereof, the L/C Issuer will also deliver to the Borrower and the Administrative Agent a true and complete copy of such Letter of Credit or amendment. 
 (c) Drawings and Reimbursements; Funding of Participations. 
 (i) Upon receipt from the beneficiary of any Letter of Credit issued for the account of the Borrower or any Restricted Subsidiary of any
notice of a drawing under such Letter of Credit, the L/C Issuer shall notify the Borrower and the Administrative Agent thereof. Not later than 11:00 a.m. on the date of any payment by the L/C Issuer under a Letter of Credit (each such date, an
“Honor Date”), the Borrower shall reimburse the L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower fails to so reimburse the L/C Issuer by such time, the Administrative
Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Lender’s Applicable Percentage thereof. In such event, the Borrower shall be
deemed to have requested a Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.02 for the principal amount of
Base Rate Loans, but subject to the amount of the unutilized portion of the Aggregate Commitments and the conditions set forth in Section 4.02 (other than the delivery of a Loan Notice). Any notice given by the L/C Issuer or the
Administrative Agent pursuant to this Section 2.03(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding
effect of such notice. 
 (ii) Each Lender shall make funds available to the Administrative Agent for the account of the L/C
Issuer at the Administrative Agent’s Office in an amount equal to its Applicable Percentage of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the
provisions of Section 2.03(c)(v), each Lender that so makes funds available shall be deemed to have made a Loan which is a Base Rate Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the
L/C Issuer. 
 (iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Borrowing of Base Rate Loans
because the conditions set forth in Section 4.02 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from 

  


					
		 	33	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand
(together with interest) and shall bear interest at the Default Rate. In such event, each Lender’s payment to the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.03(c)(iv) shall be deemed payment in
respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.03(c). 
 (iv) Until each Lender funds its Loan or L/C Advance pursuant to this Section 2.03(c) to reimburse the L/C Issuer for any
amount drawn under any Letter of Credit, interest in respect of such Lender’s Applicable Percentage of such amount shall be solely for the account of the L/C Issuer. 
 (v) Each Lender’s obligation to make Loans or L/C Advances to reimburse the L/C Issuer for amounts drawn under Letters of Credit, as
contemplated by this Section 2.03(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against
the L/C Issuer, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided,
however, that each Lender’s obligation to make Loans pursuant to this Section 2.03(c) is subject to the conditions set forth in Section 4.02 (other than delivery by the Borrower of a Loan Notice). No such making
of an L/C Advance shall relieve or otherwise impair the obligation of the Borrower to reimburse the L/C Issuer for the amount of any payment made by the L/C Issuer under any Letter of Credit, together with interest as provided herein. 
 (vi) If any Lender fails to make available to the Administrative Agent for the account of the L/C Issuer any amount required to be paid by
such Lender pursuant to the foregoing provisions of this Section 2.03(c) by the time specified in Section 2.03(c)(ii), the L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent), on
demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the L/C Issuer at a rate per annum equal to the greater of the Federal Funds Rate and a
rate determined by the L/C Issuer in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the L/C Issuer in connection with the foregoing. If such Lender pays
such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Loan included in the relevant Borrowing or L/C Advance in respect of the relevant L/C Borrowing, as the case may be. A certificate of the L/C
Issuer submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error. 
  


					
		 	34	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (d) Repayment of Participations. 
 (i) At any time after the L/C Issuer has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C
Advance in respect of such payment in accordance with Section 2.03(c), if the Administrative Agent receives for the account of the L/C Issuer any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly
from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Applicable Percentage thereof (appropriately adjusted, in the case of
interest payments, to reflect the period of time during which such Lender’s L/C Advance was outstanding) in the same funds as those received by the Administrative Agent. 
 (ii) If any payment received by the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.03(c)(i) is
required to be returned under any of the circumstances described in Section 10.05 (including pursuant to any settlement entered into by the L/C Issuer in its discretion), each Lender shall pay to the Administrative Agent for the account
of the L/C Issuer its Applicable Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate
from time to time in effect. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement. 
 (e) Obligations Absolute. The obligation of the Borrower to reimburse the L/C Issuer for each drawing under each Letter of
Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement regardless of any circumstances, including any of the following: 
 (i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other Loan Document; 
 (ii) the existence of any claim, counterclaim, setoff, defense or other right that the Borrower or any Restricted Subsidiary may have at
any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the L/C Issuer or any other Person, whether in connection with this Agreement, the
transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction; 
 (iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit; 
 (iv) any payment by the L/C Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the L/C
Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee
of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law; or 
  


					
		 	35	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (v) any other circumstance or happening whatsoever, whether or not similar to any of the
foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any Restricted Subsidiary. 
 The Borrower or the applicable Restricted Subsidiary that is the account party thereon, as the case may be, shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it
and, in the event of any claim of noncompliance with the Borrower’s or such Restricted Subsidiary’s instructions or other irregularity, the Borrower or such Restricted Subsidiary will immediately notify the L/C Issuer. The Borrower and any
such Restricted Subsidiary shall be conclusively deemed to have waived any such claim against the L/C Issuer and its correspondents unless such notice is given as aforesaid. 
 (f) Role of L/C Issuer. Each Lender and the Borrower agree that, in paying any drawing under a Letter of Credit, the L/C Issuer
shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the
authority of the Person executing or delivering any such document. None of the L/C Issuer, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of the L/C Issuer shall be liable to any
Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Issuer Document. The Borrower and each Loan Party hereby assume all risks of the acts or
omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower or a Loan Party, as the case may be, pursuing
such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the L/C Issuer, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or
assignee of the L/C Issuer shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.03(e); provided, however, that anything in such clauses to the contrary
notwithstanding, the Borrower or a Loan Party, as the case may be, may have a claim against the L/C Issuer, and the L/C Issuer may be liable to the Borrower or a Loan Party, as the case may be, to the extent, but only to the extent, of any direct,
as opposed to consequential or exemplary, damages suffered by the Borrower or such Loan Party, as the case may be, which the Borrower or such Loan Party proves were caused by the L/C Issuer’s willful misconduct or gross negligence or the L/C
Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in
limitation of the foregoing, the L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the L/C Issuer shall not be
responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason. The L/C Issuer shall deliver to the Borrower or a Restricted Subsidiary, as the case may be, copies of any documents purporting to assign or transfer a Letter of Credit issued for the account of the Borrower or
such Restricted Subsidiary. The failure of L/C Issuer to deliver such documents will not relieve the Borrower or any Restricted Subsidiary of its obligations hereunder. 
  


					
		 	36	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (g) Cash Collateral. Upon the request of the Administrative Agent, (i) if the
L/C Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing and the conditions set forth in Section 4.02 to a Borrowing cannot be met, or (ii) if, as of the
Letter of Credit Expiration Date, any L/C Obligation for any reason remains outstanding, the Borrower shall, in each case, immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations. Sections 2.05 and
8.02(c) set forth certain additional requirements to deliver Cash Collateral hereunder. For purposes of this Section 2.03, Section 2.05 and Section 8.02(c), “Cash Collateralize” means to
pledge and deposit with or deliver to the Administrative Agent, for the benefit of the L/C Issuer and the Lenders, as Collateral for the L/C Obligations, cash or deposit account balances pursuant to documentation in form and substance satisfactory
to the Administrative Agent and the L/C Issuer (which documents are hereby consented to by the Lenders). Derivatives of such term have corresponding meanings. The Borrower hereby grants to the Administrative Agent, for the benefit of the L/C Issuer
and the Lenders, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Cash Collateral shall be maintained in blocked, non-interest bearing deposit accounts at Wachovia Bank and may be
invested in Cash Equivalents. If at any time during which Cash Collateral is required to be maintained in respect of L/C Obligations, the Administrative Agent determines that any funds held as Cash Collateral are subject to any right or claim of any
Person other than the Administrative Agent or that the total amount of such funds is less than the aggregate Outstanding Amount of all L/C Obligations, the Borrower will, forthwith upon demand by the Administrative Agent, pay to the Administrative
Agent, as additional funds to be deposited as Cash Collateral, an amount equal to the excess of (x) such aggregate Outstanding Amount over (y) the total amount of funds, if any, then held as Cash Collateral that the Administrative Agent
determines to be free and clear of any such right and claim. Upon the drawing of any Letter of Credit for which funds are on deposit as Cash Collateral, such funds shall be applied, to the extent permitted under applicable Laws, to reimburse the L/C
Issuer. To the extent that the amount of any Cash Collateral exceeds the then Outstanding Amount of L/C Obligations and so long as no Event of Default has occurred and is continuing, the excess shall be refunded to the Borrower. 
 (h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the L/C Issuer and the Borrower, when a Letter of Credit is
issued, (i) the Borrower may specify that either the rules of the ISP or the rules of the Uniform Customs and Practice for Documentary Credits (“UCP”), as most recently published by the International Chamber of Commerce at the time of
issuance, apply to each standby Letter of Credit, and (ii) the rules of the UCP shall apply to each commercial Letter of Credit. 
 (i) Conflict with Issuer Documents. In the event of any conflict between the terms hereof and the terms of any Issuer Document, the terms hereof shall control. 
 (j) Letters of Credit Issued for Restricted Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder
is in support of any obligations of, or is for the account of, a Restricted Subsidiary, the Borrower shall be obligated to reimburse the L/C 

  


					
		 	37	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
Issuer hereunder for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the
account of Restricted Subsidiaries inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of such Restricted Subsidiaries. 
 2.04 Swing Line Loans. 
 (a) The Swing Line. Subject to the terms and conditions set forth herein, the Swing Line Lender agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.04, to make loans (each such loan, a
“Swing Line Loan”) to the Borrower from time to time on any Business Day during the Availability Period in an aggregate amount not to exceed at any time outstanding the amount of the Swing Line Sublimit, notwithstanding the fact
that such Swing Line Loans, when aggregated with the Applicable Percentage of the Outstanding Amount of Loans and L/C Obligations of the Lender acting as Swing Line Lender, may exceed the amount of such Lender’s Commitment; provided,
however, that after giving effect to any Swing Line Loan, (i) the Total Outstandings shall not exceed the Aggregate Commitments of all the Lenders, and (ii) the aggregate Outstanding Amount of the Loans of any Lender, plus
such Lender’s Applicable Percentage of the Outstanding Amount of all L/C Obligations, plus such Lender’s Applicable Percentage of the Outstanding Amount of all Swing Line Loans shall not exceed such Lender’s Commitment, and
provided, further, that the Borrower shall not use the proceeds of any Swing Line Loan to refinance any outstanding Swing Line Loan. Within the foregoing limits, and subject to the other terms and conditions hereof, the Borrower may
borrow under this Section 2.04, prepay under Section 2.05, and reborrow under this Section 2.04. Each Swing Line Loan shall be a Base Rate Loan. Immediately upon the making of a Swing Line Loan, each Lender shall
be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swing Line Lender a risk participation in such Swing Line Loan in an amount equal to the product of such Lender’s Applicable Percentage times the
amount of such Swing Line Loan. 
 (b) Borrowing Procedures. Each Swing Line Borrowing shall be made upon the
Borrower’s irrevocable notice to the Swing Line Lender and the Administrative Agent, which may be given by telephone. Each such notice must be received by the Swing Line Lender and the Administrative Agent not later than 1:00 p.m. on the
requested borrowing date, and shall specify (i) the amount to be borrowed, which shall be a minimum of $100,000, and (ii) the requested borrowing date, which shall be a Business Day. Each such telephonic notice must be confirmed promptly
by delivery to the Swing Line Lender and the Administrative Agent of a written Swing Line Loan Notice, appropriately completed and signed by a Responsible Officer of General Partner, in its capacity as the sole general partner of the Borrower.
Promptly after receipt by the Swing Line Lender of any telephonic Swing Line Loan Notice, the Swing Line Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has also received such Swing Line
Loan Notice and, if not, the Swing Line Lender will notify the Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swing Line Lender has received notice (by telephone or in writing) from the Administrative Agent
(including at the request of any Lender) prior to 2:00 p.m. on the date of the proposed Swing Line Borrowing (A) directing the Swing Line Lender not to make such Swing Line Loan as a result of the limitations set forth in the proviso to
the first sentence of Section 2.04(a), or (B) that one or more of the applicable conditions specified in Article IV is 

  


					
		 	38	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
not then satisfied, then, subject to the terms and conditions hereof, the Swing Line Lender will, not later than 3:00 p.m. on the borrowing date specified in
such Swing Line Loan Notice, make the amount of its Swing Line Loan available to the Borrower at its office by crediting the account of the Borrower on the books of the Swing Line Lender in immediately available funds. 
 (c) Refinancing of Swing Line Loans. 
 (i) The Swing Line Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swing Line Lender to so request on its behalf), that each
Lender make a Base Rate Loan in an amount equal to such Lender’s Applicable Percentage of the amount of Swing Line Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Loan Notice for
purposes hereof) and in accordance with the requirements of Section 2.02, without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion of the Aggregate
Commitments and the conditions set forth in Section 4.02. The Swing Line Lender shall furnish the Borrower with a copy of the applicable Loan Notice promptly after delivering such notice to the Administrative Agent. Each Lender shall
make an amount equal to its Applicable Percentage of the amount specified in such Loan Notice available to the Administrative Agent in immediately available funds for the account of the Swing Line Lender at the Administrative Agent’s Office not
later than 1:00 p.m. on the day specified in such Loan Notice, whereupon, subject to Section 2.04(c)(ii), each Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the Borrower in such amount. The
Administrative Agent shall remit the funds so received to the Swing Line Lender. 
 (ii) If for any reason any Swing Line Loan
cannot be refinanced by such a Borrowing in accordance with Section 2.04(c)(i), the request for Base Rate Loans submitted by the Swing Line Lender as set forth herein shall be deemed to be a request by the Swing Line Lender that each of
the Lenders fund its risk participation in the relevant Swing Line Loan and each Lender’s payment to the Administrative Agent for the account of the Swing Line Lender pursuant to Section 2.04(c)(i) shall be deemed payment in respect
of such participation. 
 (iii) If any Lender fails to make available to the Administrative Agent for the account of the Swing
Line Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.04(c) by the time specified in Section 2.04(c)(i), the Swing Line Lender shall be entitled to recover from such
Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swing Line Lender at a rate per
annum equal to the greater of the Federal Funds Rate and a rate determined by the Swing Line Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the
Swing Line Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Loan included in the 

  


					
		 	39	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
relevant Borrowing or funded participation in the relevant Swing Line Loan, as the case may be. A certificate of the Swing Line Lender submitted to any
Lender (through the Administrative Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error. 
 (iv) Each Lender’s obligation to make Loans or to purchase and fund risk participations in Swing Line Loans pursuant to this Section 2.04(c) shall be absolute and unconditional and shall not be
affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swing Line Lender, the Borrower or any other Person for any reason whatsoever, (B) the
occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Loans pursuant to this
Section 2.04(c) is subject to the conditions set forth in Section 4.02. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swing Line Loans, together with interest
as provided herein. 
 (d) Repayment of Participations. 
 (i) At any time after any Lender has purchased and funded a risk participation in a Swing Line Loan, if the Swing Line Lender receives any
payment on account of such Swing Line Loan, the Swing Line Lender will distribute to such Lender its Applicable Percentage thereof in the same funds as those received by the Swing Line Lender. 
 (ii) If any payment received by the Swing Line Lender in respect of principal or interest on any Swing Line Loan is required to be
returned by the Swing Line Lender under any of the circumstances described in Section 10.05 (including pursuant to any settlement entered into by the Swing Line Lender in its discretion), each Lender shall pay to the Swing Line Lender
its Applicable Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the Federal Funds Rate. The Administrative Agent will make
such demand upon the request of the Swing Line Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement. 
 (e) Interest for Account of Swing Line Lender. The Swing Line Lender shall be responsible for invoicing the Borrower for interest
on the Swing Line Loans. Until each Lender funds its Base Rate Loan or risk participation pursuant to this Section 2.04 to refinance such Lender’s Applicable Percentage of any Swing Line Loan, interest in respect of such Applicable
Percentage shall be solely for the account of the Swing Line Lender. 
 (f) Payments Directly to Swing Line Lender. The
Borrower shall make all payments of principal and interest in respect of the Swing Line Loans directly to the Swing Line Lender. 
  


					
		 	40	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 2.05 Prepayments. 
 (a) The Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay Loans made to it in
whole or in part, without premium or penalty; provided that (i) such notice must be received by the Administrative Agent not later than noon: (A) three Business Days prior to any date of prepayment of Eurodollar Rate Loans and
(B) on the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof or, if less, the Outstanding Amount of such
Loans; (iii) any prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall
specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid and, if Eurodollar Rate Loans are to be prepaid, the Interest Period(s) of such Loans. The Administrative Agent will promptly notify each Lender of its receipt of
each such notice, and the amount of such Lender’s Applicable Percentage of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest on the amount prepaid, together with any additional amounts required pursuant to Section 3.05. Each such
prepayment shall be applied to the Loans of the Lenders in accordance with their respective Applicable Percentages. 
 (b) The
Borrower may, upon notice to the Swing Line Lender (with a copy to the Administrative Agent), at any time or from time to time, voluntarily prepay Swing Line Loans in whole or in part without premium or penalty; provided that (i) such
notice must be received by the Swing Line Lender and the Administrative Agent not later than 1:00 p.m. on the date of the prepayment, and (ii) any such prepayment shall be in a minimum principal amount of $100,000 or, if less, the entire
principal amount of Swing Line Loans then outstanding. Each such notice shall specify the date and amount of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such
notice shall be due and payable on the date specified therein. 
 (c) If for any reason the Outstanding Amount of all Loans at
any time exceeds the Aggregate Commitments of all the Lenders then in effect, the Borrower shall within one Business Day following demand by the Administrative Agent prepay the Revolver Loans in an aggregate amount equal to such excess. 

(d) Any Net Cash Proceeds that are Excess Sale Proceeds shall be immediately applied as a mandatory prepayment on the Loans.

 (e) Any Extraordinary Receipts shall be immediately applied as a mandatory prepayment on the Loans; provided,
however, that prepayments under this Section 2.05(e) shall not be required until the aggregate amount of unapplied Extraordinary Receipts exceeds $2,000,000. 
  


					
		 	41	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (f) If, for any reason, the Initial Public Offering is not consummated on the Business
Day immediately following the Closing Date, (i) the Borrower shall immediately make a mandatory prepayment on the Loans in an amount equal to the Outstanding Amount of the Loans at such time and (ii) the Aggregate Commitments hereunder
shall be terminated. 
 (g) Each prepayment of the Loans under Section 2.05(c), (d), (e) or
(f) shall be accompanied by all interest then accrued and unpaid on the principal so prepaid, together with any additional amounts required pursuant to Section 3.05. Any principal or interest prepaid pursuant to this Section
shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. Each such prepayment shall be applied to the Revolver Loans of the Lenders in accordance with their
respective Applicable Percentage. 
 (h) Each prepayment under Section 2.05(c), (d) or
(e) shall be applied ratably as follows: (i) first to prepay the Outstanding Amount of the Loans and (ii) second, to repay the Outstanding Amount of the Swing Line Loans. 
 (i) The Aggregate Commitments shall be reduced, dollar for dollar, by the amount of all prepayments of the Loans under
Section 2.05(d), or (e). 
 2.06 Termination or Reduction of Commitments. The Borrower may, upon notice to the
Administrative Agent, terminate the Aggregate Commitments, or from time to time permanently reduce the Aggregate Commitments; provided that (i) any such notice shall be received by the Administrative Agent not later than noon three
Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $1,000,000 or any whole multiple of $500,000 in excess thereof, (iii) the Borrower shall not terminate or
reduce the Aggregate Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Outstandings would exceed the Aggregate Commitments of all the Lenders and (iv) if, after giving effect to any reduction of
the Aggregate Commitments, the Letter of Credit Sublimit or the Swing Line Sublimit exceeds the amount of the Aggregate Commitments, such Sublimit shall be automatically reduced by the amount of such excess. The Administrative Agent will promptly
notify the Lenders of any such notice of termination or reduction of the Aggregate Commitments. Any reduction of the Aggregate Commitments shall be applied to the Commitment of each Revolver Lender according to its Applicable Percentage. All fees
accrued up to the effective date of any termination of the Aggregate Commitments shall be paid on the effective date of such termination. Notwithstanding anything in this Section 2.06 to the contrary, the Borrower may rescind any notice
of termination in full of the Aggregate Commitments of all the Lenders under this Section 2.06 not later than 1:00 p.m. on the Business Day before such termination was scheduled to take place if such termination would have resulted from
a refinancing of the Loans, which financing shall not be consummated or shall otherwise be delayed. 
  


					
		 	42	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 2.07 Repayment of Loans. The Borrower shall repay on the Maturity Date the aggregate principal
amount of Revolver Loans outstanding on such date. The Borrower shall repay each Swing Line Loan on the earlier to occur of (i) the date ten Business Days after such Loan is made and (ii) the Maturity Date. 
 2.08 Interest. 
 (a)
Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Eurodollar Rate for such Interest
Period plus the Applicable Rate; (ii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate and
(iii) each Swing Line Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate with respect to Base Rate Loans. 
 (b) (i) If any amount of principal of any Loan is not paid when due (without regard to any applicable grace periods), whether an
installment, at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws. 

(ii) If any amount (other than principal of any Loan) payable by the Borrower under any Loan Document is not paid when due (without
regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then upon the request of the Required Lenders, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal
to the Default Rate to the fullest extent permitted by applicable Laws. 
 (iii) Upon the request of the Required Lenders,
while any Event of Default exists, the Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by
applicable Laws. 
 (iv) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be
due and payable upon demand. 
 (c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date
applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any Insolvency Proceeding. The
covenant to pay interest at the rates provided hereunder shall not merge in any judgment relating to the Obligations. 
 2.09 Fees.

 (a) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the account of each Lender in
accordance with its Applicable Percentage a Letter of Credit fee 

  


					
		 	43	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
(the “Letter of Credit Fee”) for each Letter of Credit issued for the account of the Borrower or a Restricted Subsidiary, as the case may
be, equal to the Applicable Rate with respect to Eurodollar Rate Loans times the daily amount available to be drawn under such Letter of Credit. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the
amount of such Letter of Credit shall be determined in accordance with Section 1.06. Letter of Credit Fees shall be (i) computed on a quarterly basis in arrears and (ii) due and payable within fifteen (15) days of the last
Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand. If there is any change in the
Applicable Rate during any quarter, the daily amount available to be drawn under each Letter of Credit shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.
Notwithstanding anything to the contrary contained herein, upon the request of the Administrative Agent or the Required Lenders, while any Obligation bears interest at the Default Rate pursuant to Section 2.08(b), all Letter of Credit
Fees shall accrue at the Default Rate. 
 (b) Fronting Fee and Documentary and Processing Charges Payable to L/C
Issuer. The Borrower shall pay directly to the L/C Issuer for its own account a fronting fee with respect to each Letter of Credit issued for the account of the Borrower or a Restricted Subsidiary, as the case may be, equal to the greater
of (i) $150 or (ii) one-eighth percent (0.125%) per annum, computed on the daily amount available to be drawn under such Letter of Credit on a quarterly basis in arrears. Such fronting fee shall be due and payable within fifteen
(15) days of the last Business Day of each March, June, September and December in respect of the most recently-ended quarterly period (or portion thereof, in the case of the first payment), commencing with the first such date to occur after the
issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined
in accordance with Section 1.06. In addition, the Borrower shall pay directly to the L/C Issuer for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the
L/C Issuer relating to letters of credit as from time to time in effect. Such customary fees and standard costs and charges are due and payable within fifteen (15) days after demand therefore and are nonrefundable. 
 (c) Administrative Agent’s Fees. In addition to all other amounts due to Administrative Agent under the Loan Documents, the
Borrower will pay fees to Administrative Agent as described in the Fee Letter. 
 (d) Commitment Fees. The
Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Applicable Percentage, a commitment fee equal to the Applicable Rate with respect to Commitment Fees times the actual daily amount by which
the Aggregate Commitments of all the Lenders exceed the Outstanding Amount of Loans and L/C Obligations (but excluding, for the avoidance of doubt, the Swing Line Loans). The commitment fees shall accrue at all times during the Availability Period
including at any time during which one or more of the conditions in Article IV are not met, and shall be due and payable quarterly in arrears within fifteen (15) days of the last Business Day of each March, June, September and December,
commencing with the first such date to occur after the Closing 

  


					
		 	44	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
Date, and on the Maturity Date. The commitment fees shall be calculated quarterly in arrears, and if there is any change in the Applicable Rate during any
quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect. 
 (e) Other Fees. 
 (i) The Borrower shall pay to the Arrangers and the Administrative Agent for their own respective accounts fees in the amounts and at the times specified in the Fee Letter. Such fees shall be fully earned when paid
and shall not be refundable for any reason whatsoever. 
 (ii) The Borrower shall pay to the Lenders such fees as shall have
been separately agreed upon in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever. 
 2.10 Computation of Interest and Fees. 
 (a) All computations of interest for Base Rate Loans when the Base Rate is determined by Wachovia Bank’s “prime rate” shall be made on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed. All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day
year). Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same
day on which it is made shall, subject to Section 2.12(a), bear interest for one day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest
error. 
 (b) If, as a result of any restatement of or other adjustment to the financial statements of the Borrower or for any
other reason, the Borrower or the Lenders determine that (i) the Consolidated Leverage Ratio as calculated by the Borrower as of any applicable date was inaccurate and (ii) a proper calculation of the Consolidated Leverage Ratio would have
resulted in higher pricing for such period, the Borrower shall immediately and retroactively be obligated to pay to the Administrative Agent for the account of the Lenders, promptly on demand by the Administrative Agent (or, after the occurrence of
an actual or deemed entry of an order for relief with respect to the Borrower under the Bankruptcy Code of the United States, automatically and without further action by the Administrative Agent, Swing Line Lender, any Lender or the L/C Issuer), an
amount equal to the excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period. This paragraph shall not limit the rights of the Administrative Agent, Swing
Line Lender, any Lender or the L/C Issuer, as the case may be, under Section 2.03(c)(iii), 2.08(b) or 2.09(a) or under Article VIII. The Borrower’s obligations under this paragraph shall survive the termination
of the Aggregate Commitments and the repayment of all other Obligations hereunder. 
  


					
		 	45	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 2.11 Evidence of Debt. 
 (a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the
Administrative Agent in the ordinary course of business in accordance with its usual practice. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Credit
Extensions made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing
with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the
Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Note, which shall
evidence such Lender’s Revolver Loans in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto.

 (b) In addition to the accounts and records referred to in subsection (a), each Lender and the Administrative Agent
shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swing Line Loans. In the event of any conflict between the accounts and records
maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. 
 2.12 Payments Generally; Administrative Agent’s Clawback. 
 (a) General. All payments to be made by the Borrower shall be made without condition or deduction for any counterclaim, defense,
recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative
Agent’s Office in Dollars and in immediately available funds not later than 2:00 p.m. on the date specified herein. The Administrative Agent will promptly distribute to each Lender its Applicable Percentage (or other applicable share as
provided herein) of such payment in like funds as received by wire transfer to such Lender’s Lending Office. All payments received by the Administrative Agent after 2:00 p.m. shall be deemed received on the next succeeding Business Day and any
applicable interest or fee shall continue to accrue. If any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected
in computing interest or fees, as the case may be; except that this sentence shall not apply to the Maturity Date. 
 (b) (i)
Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing of Eurodollar Rate Loans (or, in the case of any Borrowing of Base


  


					
		 	46	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
Rate Loans, prior to 12:00 noon on the date of such Borrowing) that such Lender will not make available to the Administrative Agent such Lender’s share
of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 (or, in the case of a Borrowing of Base Rate Loans, that such Lender has made such share
available in accordance with and at the time required by Section 2.02) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the
applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest
thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the greater of the
Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Administrative Agent in
connection with the foregoing and (B) in the case of a payment to be made by the Borrower, the Applicable Rate with respect to Base Rate Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or
an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the
amount so paid shall constitute such Lender’s Loan included in such Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the
Administrative Agent. 
 (ii) Payments by the Borrower; Presumptions by Administrative Agent. Unless the Administrative
Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the L/C Issuer hereunder that the Borrower will not make such payment, the Administrative
Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the L/C Issuer, as the case may be, the amount due. In such event, if the Borrower
has not in fact made such payment, then each of the Lenders or the L/C Issuer, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the L/C Issuer, in immediately
available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank compensation. 
 A notice of the Administrative Agent to any
Lender or the Borrower with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error. 
 (c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the 

  


					
		 	47	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
foregoing provisions of this Article II, and such funds are not made available to the Borrower by the Administrative Agent because the conditions to
the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without
interest. 
 (d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Loans, to fund
participations in Letters of Credit and Swing Line Loans and to make payments pursuant to Section 10.04(c) are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under
Section 10.04(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to
purchase its participation or to make its payment under Section 10.04(c). 
 (e) Funding Source. Nothing
herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or
manner. 
 2.13 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise,
obtain payment in respect of any principal of or interest on any of the Loans made by it, or the participations in L/C Obligations or in Swing Line Loans held by it resulting in such Lender’s receiving payment of a proportion of the aggregate
amount of such Loans, participations and repayment obligations and accrued interest thereon or fees with respect thereto greater than its Applicable Percentage thereof as provided herein, then the Lender receiving such greater proportion
shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and subparticipations in L/C Obligations and Swing Line Loans of the other Lenders, or make such other
adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them,
provided that: 
 (a) if any such participations or subparticipations are purchased and all or any portion of the
payment giving rise thereto is recovered, such participations or subparticipations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; 
 (b) the provisions of this Section shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in
accordance with the express terms of this Agreement, or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or subparticipations in L/C Obligations or Swing Line Loans to
any assignee or participant, other than to the Borrower or any Restricted Subsidiary thereof (as to which the provisions of this Section shall apply). 
  


					
		 	48	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under
applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct
creditor of such Loan Party in the amount of such participation. 
 2.14 Increase in Commitments. 
 (a) Request for Increase. Provided no Default has occurred and is continuing, upon notice to the Administrative Agent (which shall
promptly notify the Lenders), the Borrower may from time to time request an increase in the Aggregate Commitments of all the Lenders; provided that (i) any such request for an increase shall be in a minimum amount of $5,000,000, (ii) the
Borrower may make a maximum of three such requests during the Availability Period, and (iii) after giving effect to such increase in the Aggregate Commitments, the Aggregate Commitments do not exceed $400,000,000. At the time of sending such
notice, the Borrower may request all or part of such increase from the Lenders and, if it does so, shall specify (in consultation with the Administrative Agent) the time period within which each Revolver Lender who desires to commit to such increase
is requested to respond. 
 (b) Lender Elections to Increase. Each Lender may notify the Administrative Agent within
such time period whether or not it agrees to increase its Commitment and, if so, whether by an amount equal to, greater than, or less than its Applicable Percentage of such requested increase. Any Lender not responding within such time period shall
be deemed to have declined to increase its Commitment. 
 (c) Notification by Administrative Agent; Additional Lenders.
The Administrative Agent shall notify the Borrower and each Lender of the Lenders’ responses to each request made hereunder. To achieve the full amount of a requested increase and subject to the approval of the Administrative Agent and the L/C
Issuer (which approvals shall not be unreasonably withheld), the Borrower may also invite additional Eligible Assignees to become Lenders pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel.
It shall not be a condition to obtaining an increase in the Aggregate Commitments that the full amount of such increase requested by the Borrower be approved by the Lenders or any additional Eligible Assignees. If less than the full amount of the
increase requested by the Borrower is approved by the Lenders and any additional Eligible Assignee, the Borrower may, at its option, accept the amount of the increase so approved, or the Borrower may withdraw its request for such increase, in which
case the Borrower shall be deemed not to have made a request for such increase. 
 (d) Effective Date and Allocations.
If the Aggregate Commitments are increased in accordance with this Section, the Administrative Agent and the Borrower shall determine the effective date (the “Increase Effective Date”) and the final allocation of such increase. The
Administrative Agent shall promptly notify the Borrower and the Lenders of the final amount and allocation of such increase and the Increase Effective Date. 
 (e) Conditions to Effectiveness of Increase. As a condition precedent to such increase, the Borrower shall deliver to the
Administrative Agent a certificate of each Loan Party dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of such Loan Party (i) certifying and attaching the resolutions adopted by


  


					
		 	49	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
such Loan Party approving or consenting to such increase, and (ii) in the case of the Borrower, certifying that, before and after giving effect to such
increase, (A) the representations and warranties contained in Article V and the other Loan Documents are true and correct on and as of the Increase Effective Date, except to the extent that such representations and warranties
specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.14, the representations and warranties contained in subsections (a) and
(b) of Section 5.05 shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 6.01, and (B) no Default exists. The Borrower
shall prepay any Revolver Loans outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 3.05) to the extent necessary to keep the outstanding Loans ratable with any revised Applicable
Percentages arising from any nonratable increase in the Commitments under this Section. 
 (f) Conflicting Provisions.
This Section shall supersede any provisions in Sections 2.13 or 10.01 to the contrary. 
 ARTICLE III. 
 TAXES, YIELD PROTECTION AND ILLEGALITY 
 3.01 Taxes. 
 (a) Payments Free of Taxes. Any and all payments by or on account of any obligation of
the Borrower hereunder or under any other Loan Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if the Borrower shall be required by applicable Law to deduct
any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased (and in the case of interest, the amount of interest shall be increased) as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or L/C Issuer, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions and (iii) the Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable Law. 
 (b) Payment of Other Taxes by the Borrower. Without limiting the provisions of subsection (a) above, the Borrower shall timely
pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 
 (c) Indemnification by the
Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and the L/C Issuer, within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes
imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Lender or the L/C Issuer, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or
the L/C Issuer (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender or the L/C Issuer, shall be conclusive absent manifest error. 
  


					
		 	50	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the
return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 
 (e)
Status of Lenders. Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent),
at the time or times prescribed by applicable Law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable Law as will permit such payments to be made without
withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the Borrower or the
Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. 
 Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States, any Foreign Lender
shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter
upon the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable: 
 (i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the
United States is a party, 
 (ii) duly completed copies of Internal Revenue Service Form W-8ECI, 
 (iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code,
(x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section
881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or 
 (iv) any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in United States federal
withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable Law to permit the Borrower to determine the withholding or deduction required to be made. 
  


					
		 	51	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (f) Treatment of Certain Refunds. If the Administrative Agent, any Lender or the
L/C Issuer determines, in its sole discretion, that it has received a credit for, or refund of, any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant
to this Section, it shall pay to the Borrower an amount equal to such credit or refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving
rise to such credit or refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or the L/C Issuer, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect
to such refund), provided that the Borrower, upon the request of the Administrative Agent, such Lender or the L/C Issuer, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Administrative Agent, such Lender or the L/C Issuer in the event the Administrative Agent, such Lender or the L/C Issuer is denied the credit by, or required to repay such refund to, such Governmental
Authority. This subsection shall not be construed to require the Administrative Agent, any Lender or the L/C Issuer to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any
other Person. 
 3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has
asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or to determine or charge interest rates based upon the Eurodollar Rate, or any Governmental Authority has imposed
material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of
such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such
determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans,
either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon
any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted. 
 3.03 Inability
to Determine Rates. If the Required Lenders determine that for any reason in connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the
London interbank eurodollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, (b) adequate and reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period with respect to
a proposed Eurodollar Rate Loan, or (c) the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, the
Administrative Agent will promptly so notify the Borrower and each Lender. Thereafter, the 

  


					
		 	52	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent (upon the instruction of the Required
Lenders) revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a
request for a Borrowing of Base Rate Loans in the amount specified therein. 
 3.04 Increased Costs; Reserves on Eurodollar Rate Loans.

 (a) Increased Costs Generally. If any Change in Law shall: 
 (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against
assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement contemplated by Section 3.04(e)) or the L/C Issuer; 
 (ii) subject any Lender or the L/C Issuer to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any
participation in a Letter of Credit or any Eurodollar Rate Loan made by it, or change the basis of taxation of payments to such Lender or the L/C Issuer in respect thereof (except for Indemnified Taxes or Other Taxes covered by
Section 3.01 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or the L/C Issuer); or 
 (iii) impose on any Lender or the L/C Issuer or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Rate Loans made by such Lender or any Letter of Credit or
participation therein; 
 and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Rate
Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or the L/C Issuer of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue
any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the L/C Issuer hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or the L/C Issuer, the Borrower will
pay to such Lender or the L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer, as the case may be, for such additional costs incurred or reduction suffered. 
 (b) Capital Requirements. If any Lender or the L/C Issuer determines that any Change in Law affecting such Lender or the L/C Issuer
or any Lending Office of such Lender or such Lender’s or the L/C Issuer’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the L/C Issuer’s
capital or on the capital of such Lender’s or the L/C Issuer’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender,
or the Letters of Credit issued by the L/C Issuer, to a level below that which such Lender or the L/C Issuer or such Lender’s or the L/C Issuer’s holding company could have achieved but for such Change in Law (taking into consideration
such Lender’s or the L/C Issuer’s policies and the policies of such Lender’s or 

  


					
		 	53	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
the L/C Issuer’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the L/C Issuer, as
the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer or such Lender’s or the L/C Issuer’s holding company for any such reduction suffered. 
 (c) Certificates for Reimbursement. A certificate of a Lender or the L/C Issuer setting forth the amount or amounts necessary to
compensate such Lender or the L/C Issuer or its holding company, as the case may be, as specified in subsection (a) or (b) of this Section and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such
Lender or the L/C Issuer, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof. 
 (d) Delay in Requests. Failure or delay on the part of any Lender or the L/C Issuer to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of such
Lender’s or the L/C Issuer’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the L/C Issuer pursuant to the foregoing provisions of this Section for any increased costs
incurred or reductions suffered more than nine months prior to the date that such Lender or the L/C Issuer, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or
the L/C Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period
of retroactive effect thereof). 
 (e) Reserves on Eurodollar Rate Loans. The Borrower shall pay to each Lender, as
long as such Lender shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional interest on the
unpaid principal amount of each Eurodollar Rate Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive), which shall be due and
payable on each date on which interest is payable on such Loan, provided the Borrower shall have received at least ten (10) days’ prior notice (with a copy to the Administrative Agent) of such additional interest from such Lender.
If a Lender fails to give notice ten (10) days prior to the relevant Interest Payment Date, such additional interest shall be due and payable ten (10) days from receipt of such notice. 
 3.05 Compensation for Losses. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrower shall promptly
compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of: 
 (a)
any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

 (b) any failure by the Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow,
continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by the Borrower; or 
  


					
		 	54	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (c) any assignment of a Eurodollar Rate Loan on a day other than the last day of the
Interest Period therefor as a result of a request by the Borrower pursuant to Section 10.13; 
 including any loss of anticipated profits and any
loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative
fees charged by such Lender in connection with the foregoing. 
 For purposes of calculating amounts payable by the Borrower to the Lenders under this
Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit or other borrowing in the London interbank eurodollar market for a comparable amount
and for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded. 
 3.06 Mitigation Obligations; Replacement
of Lenders. 
 (a) Designation of a Different Lending Office. If any Lender requests compensation under
Section 3.04, or the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, or if any Lender gives a notice pursuant to
Section 3.02, then such Lender shall use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or
affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04, as the case may be, in the future, or eliminate the need for the
notice pursuant to Section 3.02, as applicable, and (ii) in each case, would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay
all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 
 (b)
Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if any Lender delivers to the Borrower a notice pursuant to Section 3.02, or if the Borrower is required to pay any additional amount
to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, the Borrower may replace such Lender in accordance with Section 10.13. 
 3.07 Survival. All of the Borrower’s obligations under this Article III shall survive termination of the Aggregate Commitments and
repayment of all other Obligations hereunder.

 REPRESENTATIONS AND WARRANTIES 
 The Borrower represents and warrants to the Administrative Agent and the Lenders that:

simple title to or valid leasehold interests in all of its real property, including, without limitation, the Real Estate (all such real property and the nature of the Borrower’s or any of its Restricted Subsidiary’s interest therein is
disclosed on Schedule 5.22, as it may be updated from time to time) and (ii) defensible title to all of its other property (including without limitation, all real and other property in each case as reflected in the financial statements
delivered to the Administrative Agent hereunder), other than properties disposed of in the ordinary course of business or in any manner otherwise permitted under this Agreement since the date of the most recent audited consolidated balance sheet of
the Borrower and its Subsidiaries, and in each case subject to no Liens other than Liens permitted under Section 7.01 and such other defects in title as are minor in nature and such defects do not constitute a Lien that secures

granted, or (ii) any other lease, to the extent such default would reasonably be expected to have a Material Adverse Effect. All of the structures and

Borrower has reasonably concluded that such Environmental Laws and claims could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 5.10 Insurance. The properties of the Borrower and each Subsidiary are insured with financially sound and reputable insurance companies not

payable, except those which are being contested in good faith by appropriate proceedings diligently conducted and for which adequate reserves have been provided in accordance with GAAP. There is no proposed tax assessment against the Borrower or any
Restricted Subsidiary thereof that would, if made, have a Material Adverse Effect. Neither the Borrower nor any Restricted Subsidiary is party to any tax sharing agreement other than as provided in the Borrower’s Partnership Agreement.

Laws. Each Plan that is intended to qualify under Section 401(a) of the Code has received a favorable determination letter from the IRS or an 

  


					
		 	63	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
application for such a letter is currently being processed by the IRS with respect thereto and, to the best knowledge of the Borrower, nothing has occurred
which would prevent, or cause the loss of, such qualification. Each Loan Party and each ERISA Affiliate have made all required contributions to each Plan subject to Section 412 of the Code, and no application for a funding waiver or an
extension of any amortization period pursuant to Section 412 of the Code has been made with respect to any Plan.

the Borrower or a Subsidiary in the amounts specified on Part (a) of Schedule 5.13 or disclosed in writing to the Administrative Agent, L/C Issuer and the Lenders free and clear of all Liens other than the Liens created pursuant to
the Loan Documents. The Borrower has no equity investments in any other corporation or entity other than those specifically disclosed in Part (b) of Schedule 5.13 or disclosed in writing to the Administrative Agent, L/C Issuer and the

restrictions to which it or any of its Restricted Subsidiaries is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. No report, financial
statement, certificate or other written information furnished by or on behalf of any Loan Party to the Administrative Agent or any Lender in connection with the transactions contemplated hereby and the negotiation of this Agreement or delivered
hereunder or under any other Loan Document (in each case, as modified or supplemented by other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the

employed, by the Borrower or any Restricted Subsidiary infringes upon any rights held by any other Person. No claim or litigation regarding any of the foregoing is pending or, to the best knowledge of the Borrower, threatened, which, either

Guarantees thereof, shall not exceed the fair market value of such Loan Party’s assets, and (b) each Loan Party’s capital should be adequate for the businesses in which such Loan Party is engaged and intends to be engaged. No Loan

accordance with its terms. The Borrower shall provide updates to Schedule 5.21 upon the reasonable request of Administrative Agent. 
 5.22 Security Documents. The provisions of the Security Documents are effective to create in favor of the Administrative Agent for the benefit of the Secured Parties a legal, valid and enforceable first priority Lien (subject to
Liens permitted by Section 7.01) on all right, title and interest of the respective Loan Parties in the Collateral described therein. Except for filings completed prior to the Closing Date and as contemplated hereby and by the Loan
Documents from time to time, no filing or other action will be necessary to perfect or protect such Liens.

the terms and provisions hereof. In furtherance of the forgoing, each L/C Issuer and Lender acknowledges that certain of the Loan Parties maintain Lender Party Accounts at one or more of the Administrative Agent, L/C Issuer and Lenders as disclosed

L/C Issuer or a Lender of notice from Administrative Agent that it is exercising exclusive control over any Lender Party Account (a “Notice of Exclusive Control”), the Loan Parties are entitled to make withdrawals from the Lender

and is continuing, Administrative Agent shall be the only party entitled to make withdrawals from or otherwise give any entitlement order or other direction with respect to the Lender Party Accounts. To the extent not already occurring, each L/C
Issuer and Lender agrees to transfer, in immediately available funds by wire transfer to Administrative Agent, the amount of the collected funds credited to the deposit accounts which are Lender Party Accounts held by such L/C Issuer or Lender, and
deliver to Administrative Agent all moneys or instruments relating to such Lender Party Accounts or held therein and any other Collateral at any time Administrative Agent demands payment or delivery thereof after a Notice of Exclusive Control has
been delivered to such L/C Issuer or Lender. Each Loan Party agrees that L/C Issuer and each Lender is authorized to immediately deliver all the Collateral to Administrative Agent upon the L/C Issuer’s or Lender’s receipt of a Notice of
Exclusive Control from Administrative Agent. Neither L/C Issuer nor any Lender (other than Administrative Agent acting for the benefit of the L/C Issuer and Lenders) shall exercise any right of set-off or banker lien against any Lender Party
Account; provided that L/C Issuer and Lenders shall be entitled to charge, or set-off against a Lender Party Account and retain for its own account, any customary fees, costs, charges and expenses owed to it in connection with the opening,
operating and maintaining such Lender Party Account and for the amount of any item credited to such Lender Party Account that is subsequently returned for any reason. Notwithstanding anything in this Section 6.18 to the contrary, a
Lender may, upon notice to the Administrative Agent, elect that the accounts of the Loan Parties maintained by such Lender shall not be governed by the provisions of this Section 6.18. Upon Administrative Agent’s receipt of such
notice, such accounts shall cease to be Lender Party Accounts and the maintenance of accounts shall be subject to such account becoming an Approved Account as set forth above.

hereto or revised or updated pursuant hereto, but shall not be deemed to have cured any breach of warranty or misrepresentation resulting from the inaccuracy or incompleteness of any such Schedule(s) as it existed prior to such revision of update

required to be delivered to the Administrative Agent. 
 9.04 Reliance by Administrative Agent. The Administrative Agent shall be
entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other
distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been
made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the
satisfaction of a Lender or the L/C Issuer, the Administrative Agent may presume that such condition is satisfactory to such Lender or the L/C Issuer unless the Administrative Agent shall have received notice to the contrary from such Lender or the
L/C Issuer prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall
not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 
 9.05

The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and
to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities of Administrative Agent.

Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives

		 	92	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
retiring Administrative Agent may on behalf of the Lenders and the L/C Issuer, appoint a successor Administrative Agent meeting the qualifications set forth
above; provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and
(1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders
or the L/C Issuer under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (2) all payments, communications and
determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the L/C Issuer directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for

Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees
payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder
and under the other Loan Documents, the provisions of this Article and Section 10.04 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any
actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent. 
 Any
resignation by Wachovia Bank as Administrative Agent pursuant to this Section shall also constitute its resignation as L/C Issuer and Swing Line Lender. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder,
(a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer and Swing Line Lender, (b) the retiring L/C Issuer and Swing Line Lender shall be discharged from all of
their respective duties and obligations hereunder or under the other Loan Documents, and (c) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or
make other arrangements satisfactory to the retiring L/C Issuer to effectively assume the obligations of the retiring L/C Issuer with respect to such Letters of Credit. 
 9.07 Non-Reliance on Administrative Agent and Other Lenders. Each Lender and the L/C Issuer acknowledges that it has, independently and without reliance upon the Administrative Agent, any other Agent or any
other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the L/C Issuer also acknowledges that it
will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions
in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Issuer hereunder. 
 9.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any Insolvency Proceeding relative
to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent
shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise 
 (a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be
necessary or advisable in order to have the claims of the Lenders, the L/C Issuer and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuer and the
Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the L/C Issuer and the Administrative Agent under Sections 2.03(i), (j) and (k), 2.09 and 10.04) allowed in such

Sections 2.09 and 10.04.

consent to or accept or adopt on behalf of any Lender or the L/C Issuer any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender, the L/C Issuer, or the Swing Line Lender or to
authorize the Administrative Agent to vote in respect of the claim of any Lender, the L/C Issuer, or the Swing Line Lender in any such proceeding.

The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it, provided that approval of such procedures

originals and shall be binding on all Loan Parties, the Administrative Agent, the L/C Issuer and the Lenders. The Administrative Agent may also require that

be entitled to rely and act upon any notices (including telephonic Loan Notices and Swing Line Loan Notices) purportedly given by or on behalf of the Borrower even if (i) such notices were not made in a manner specified herein, were incomplete
or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Borrower shall indemnify the Administrative Agent, the L/C
Issuer, each Lender and the Related Parties of each of them from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of the Borrower. All telephonic notices to and

Person in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law. Neither Administrative Agent
nor any Lender shall be under any obligation to marshal any assets in favor of the Borrower, any Guarantor or any other party or against or in payment of any or all of the Obligations.

operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (v) any actual or prospective claim, litigation, investigation or proceeding relating to any
of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower, any other Loan Party or any Subsidiary thereof, and regardless of whether any Indemnitee is a party thereto, in all cases,
whether or not caused by or arising, in whole or in part, out of the negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or
related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the
Borrower or any other 

  


					
		 	99	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
Loan Party against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower or

 (c) Reimbursement by Lenders. To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under subsection (a) or (b) of this Section to be paid by it to the

Party, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount, provided that the unreimbursed expense or
indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent) or the L/C Issuer in its capacity as such, or against any Related Party of any of
the foregoing acting for the Administrative Agent (or any such sub-agent) or L/C Issuer in connection with such capacity. The obligations of the Lenders under this subsection (c) are subject to the provisions of Section 2.12(d).

 (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, the Borrower shall not

Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in subsection (b)

of all the other Obligations. 
 10.05 Payments Set Aside. To the extent that any payment by or on behalf of the Borrower is made to
the Administrative Agent, the L/C Issuer or any Lender, or the Administrative Agent, the L/C Issuer or any Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated,
declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent, the L/C Issuer or such Lender in its discretion) to be repaid to a trustee, receiver or any other party,
in connection with any Insolvency Proceeding or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally 

  


					
		 	100	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and
(b) each Lender and the L/C Issuer severally agrees to pay to the Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the
date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders and the L/C Issuer under clause (b) of the preceding sentence shall survive the
payment in full of the Obligations and the termination of this Agreement. 
 10.06 Successors and Assigns. 
 (a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby, except that the Borrower or any other Loan Party may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the
Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of this Section,
(ii) by way of participation in accordance with the provisions of subsection (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) of this Section (and
any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and
assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the L/C Issuer and the Lenders) any legal
or equitable right, remedy or claim under or by reason of this Agreement. 
 (b) Assignments by Lenders. Any Lender may
at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement; provided that 
 (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Aggregate Commitment and the Revolver Loans at the time owing to it or in the case of an assignment to a Lender or
an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Aggregate Commitment (which for this purpose includes Revolver Loans outstanding thereunder) or, if the Aggregate Commitment is not then in effect,
the principal outstanding balance of the Revolver Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if
“Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000 unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower
otherwise consents (each such consent not to be unreasonably withheld or delayed); provided, however, that concurrent assignments to members of an Assignee Group and concurrent assignments from members of an Assignee Group to a single
Eligible Assignee (or to an Eligible Assignee and members of its Assignee Group) will be treated as a single assignment for purposes of determining whether such minimum amount has been met; 
  


					
		 	101	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 (ii) each partial assignment shall be made as an assignment of a proportionate part of
all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned; 
 (iii) any assignment of a Commitment must be approved by the Administrative Agent and the L/C Issuer (such consent not to be unreasonably withheld) unless the Person that is the proposed assignee is itself a Lender (whether or not the
proposed assignee would otherwise qualify as an Eligible Assignee); and 
 (iv) the parties to each assignment shall execute
and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount, if any, required as set forth in Schedule 10.06, and the Eligible Assignee, if it shall not be a Lender, shall
deliver to the Administrative Agent an Administrative Questionnaire. 
 Subject to acceptance and recording thereof by the Administrative Agent pursuant to
subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment
and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this
Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of
Sections 3.01, 3.04, 3.05, and 10.04 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this
Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section. 
 (c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the
Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans and L/C Obligations
owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, any Lender and the L/C Issuer at
any reasonable time and from time to time upon reasonable prior notice. In addition, at any time that a request for a consent for a material or substantive change to the Loan Documents is pending, any Lender may request and receive from the
Administrative Agent a copy of the Register.

 (d) Participations. Any Lender may at any time, without the consent of, or notice
to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of
such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in L/C Obligations) owing to it); provided that (i) such
Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent,
the Lenders and the L/C Issuer shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. 
 Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce
this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any
amendment, waiver or other modification described in the first proviso to Section 10.01 that affects such Participant. Subject to subsection (e) of this Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by Law, each
Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.13 as though it were a Lender. 
 (e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under
Section 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the
Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower is notified of the participation sold to such Participant
and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.01(e) as though it were a Lender. 
 (f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any
pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a
party hereto. 
 (g) Electronic Execution of Assignments. The words “execution,” “signed,”
“signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or
enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable Law, including the Federal Electronic Signatures in Global and National
Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

 (h) Resignation as L/C Issuer or Swing Line Lender after Assignment.
Notwithstanding anything to the contrary contained herein, if at any time Wachovia Bank assigns all of its Commitment and Loans pursuant to subsection (b) above, such L/C Issuer may, (i) upon 30 days’ notice to the Borrower and the
Lenders, resign as L/C Issuer and (ii) upon 30 days’ notice to the Borrower and the Lenders, resign as Swing Line Lender. In the event of any such resignation as L/C Issuer or Swing Line Lender, the Borrower shall be entitled to appoint
from among the Lenders a successor L/C Issuer or Swing Line Lender hereunder; provided, however, that no failure by the Borrower to appoint any such successor shall affect the resignation of Wachovia Bank, as L/C Issuer or Swing Line Lender, as the
case may be. If Wachovia Bank resigns as L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C
Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c)). If Wachovia Bank resigns as Swing Line
Lender, it shall retain all the rights, powers, privileges and duties of the Swing Line Lender hereunder with respect to all Swing Line Loans outstanding as of the effective date of its resignation as Swing Line Lender, including the right to
require the Lenders to make Base Rate Loans or fund risk participations in Swing Line Loans pursuant to Section 2.03(c). Upon the appointment of a successor L/C Issuer and/or Swing Line Lender, (a) such successor shall succeed to and
become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swing Line Lender, as the case may be, and (b) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit,
if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring L/C Issuer to effectively assume the obligations of the retiring L/C Issuer with respect to such Letters of Credit. 
 10.07 Treatment of Certain Information; Confidentiality. Each of the Administrative Agent, the Lenders and the L/C Issuer agrees to maintain the
confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and representatives
(it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority
purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal
process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of
rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement, (ii) to any pledgee referred to in Section 10.06(f) or (iii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower
and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Administrative
Agent, any Lender, the L/C Issuer or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower. 
  


					
		 	104	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 For purposes of this Section, “Information” means all information received from any Loan
Party or any Subsidiary thereof relating to any Loan Party or any Subsidiary thereof or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or the L/C Issuer on a
nonconfidential basis prior to disclosure by the Borrower or any Subsidiary, provided that, in the case of information received from any Loan Party or any Subsidiary thereof after the date hereof, such information is clearly identified at the
time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care
to maintain the confidentiality of such Information as such Person would accord to its own confidential information. 
 Each of the
Administrative Agent, the Lenders and the L/C Issuer acknowledges that (a) the Information may include material non-public information concerning the Borrower or a Subsidiary, as the case may be, (b) it has developed compliance procedures
regarding the use of material non-public information and (c) it will handle such material non-public information in accordance with applicable Law, including federal, state and provincial securities Laws. 
 10.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender, the L/C Issuer and each of their respective
Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any
time held and other obligations (in whatever currency) at any time owing by such Lender, the L/C Issuer or any such Affiliate to or for the credit or the account of the Borrower or any other Loan Party against any and all of the obligations of the
Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender or the L/C Issuer, irrespective of whether or not such Lender or the L/C Issuer shall have made any demand under this Agreement or
any other Loan Document and although such obligations of the Borrower or such Loan Party may be contingent or unmatured or are owed to a branch or office of such Lender or the L/C Issuer different from the branch or office holding such deposit or
obligated on such indebtedness. The rights of each Lender, the L/C Issuer and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the L/C Issuer or their
respective Affiliates may have. Each Lender and the L/C Issuer agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the
validity of such setoff and application. 
 10.09 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any
Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender
shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted
for, charged, or received by the Administrative Agent or a Lender exceeds the 

  


					
		 	105	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or
premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the
Obligations hereunder. 
 10.10 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by
different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents constitute the entire contract
among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall
become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of
an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. 
 10.11 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection
herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the
Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as
long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding. 
 10.12 Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and
the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
 10.13 Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if the Borrower is required to pay any
additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, or if any Lender is a Defaulting Lender or in connection with any proposed amendment, modification, termination, waiver
or consent with respect to any of the provisions hereof as contemplated by Section 10.01, the consent of Required Lenders shall have been obtained but the consent of one or more of such other Lenders whose consent is required shall not
have been obtained, if any other circumstance exists hereunder that gives the Borrower the right to replace a Lender as a party hereto, then the Borrower may, at its sole expense and effort, upon notice to such Lender 

  


					
		 	106	  	[SEMGROUP ENERGY PARTNERS CREDIT AGREEMENT]










 
and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in,
and consents required by, Section 10.06), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment), provided that: 
 (a) the Borrower shall have paid to the Administrative Agent the
assignment fee specified in Section 10.06(b); 
 (b) such Lender shall have received payment of an amount equal to
the outstanding principal of its Loans and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05) from the assignee
(to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts); 
 (c) in the case of any such assignment resulting from a claim for compensation under Section 3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such
compensation or payments thereafter; and 
 (d) such assignment does not conflict with applicable Laws. 
 A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation cease to apply.
