 (b) The
Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article II, including,
without limitation, the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without

of calculating the aggregate liability of Parent under Section 2.1(a), Parent will be deemed to have incurred any such liability when incurred or paid (and such liability shall be applied toward the $7,500,000 limitation on liability set forth
in Section 2.2), regardless of the status of any insurance claims in respect thereof, and such liability (and the application thereof toward the $7,500,000 limitation on liability set forth in Section 2.2) will be reduced when any
insurance proceeds in respect thereof are actually received by Parent to the extent that Parent is not required to pay such proceeds over to any of the Partnership Entities.

 (e) The date on which notification of a claim for indemnification is received by the Indemnifying Party
shall determine whether such claim is timely made.

right to submit to Management Company a proposal to reduce the amount of the Administrative Fee for the current year if the Partnership believes, in good faith, that the G&A Services performed by the Management Company for the preceding year do
not justify payment of the full Administrative Fee for the current year. If the Partnership submits such a proposal to Management Company, Management Company agrees that it will negotiate in good faith with the Partnership to determine if the
Administrative Fee for the current year should be reduced.

Partnership Group Members, and SMEP hereby grant to Parent a right of first refusal on any proposed Transfer (other than a grant of a security interest to a bona fide third party lender or a Transfer to another Partnership Group Member) of any
Storage Tank Asset; provided, that Parent agrees to pay or to cause another Parent Entity to pay no less than 100% of the purchase price offered by a bona fide third party prospective acquiror (a “Proposed
Transferee”). 
 (b) Subject to Section 5.1(c), for so long as the Terminalling and Storage Agreement is in effect, Parent,
on behalf of itself and the other Parent Entities, and SemMaterials hereby grant to the Partnership a right of first refusal on any proposed Transfer (other than a grant of a security interest to a bona fide third party lender or a Transfer to
another Parent Entity) of any Asphalt Processing Asset; provided, in each case, that the Partnership agrees to pay or to cause another Partnership Group Member to pay no less than 100% of the purchase price offered by a Proposed Transferee.

 (c) The Parties acknowledge that any potential Transfer of assets pursuant to this Article V (such assets, the “ROFR
Assets”) shall be subject to, conditioned on and in compliance with obtaining any and all necessary consents of equityholders, noteholders or other securityholders, governmental authorities, lenders or other third parties. 

5.2 Procedures. 
 (a)
If a Partnership Group Member proposes to Transfer any ROFR Assets to a Proposed Transferee (a “Partnership Acquisition Proposal”), then the General Partner shall promptly give written notice (a “Partnership
Disposition Notice”) thereof to Parent. The Partnership Disposition Notice shall set forth the following information in respect of the proposed Transfer: (i) the name and address of the Proposed Transferee, (ii) the ROFR
Asset(s) subject to the Partnership Acquisition Proposal, (iii) the purchase price offered by such Proposed Transferee (the “Partnership Offer Price”), (iv) reasonable detail concerning any non-cash portion

 16 

 Transferee’s offer consists of consideration other than cash (or in addition to cash), the Partnership Offer Price
shall be deemed equal to the amount of any such cash plus the fair value of such non-cash consideration. No later than 45 days after Partnership’s delivery of the Partnership Disposition Notice (the “Parent Acceptance

(a) below, or (ii) Parent has elected to purchase the applicable ROFR Assets on the terms set forth in the Partnership Disposition Notice (subject to the proviso set forth in Section 5.1(a), including without limitation the
requirement to pay the Partnership Offer Price). If the Transfer by the Partnership Group Member to the Proposed Transferee is not consummated in accordance with the terms of the Partnership Acquisition Proposal within the later of
(A) 180 days after the Parent Acceptance Deadline, and (B) 10 days after the satisfaction of all consent, governmental approval or filing requirements, if any, the Partnership Acquisition Proposal shall be deemed to lapse, and
the Partnership Group Member may not Transfer any of the ROFR Assets described in the Partnership Disposition Notice without complying again with the provisions of this Article V if and to the extent then applicable. 
 (b) If a Parent Entity proposes to Transfer any ROFR Assets to a Proposed Transferee (a “Parent Acquisition Proposal”), then
Parent shall promptly give written notice (a “Parent Disposition Notice”) thereof to the General Partner. The Parent Disposition Notice shall set forth the following information in respect of the proposed Transfer:
(i) the name and address of the Proposed Transferee, (ii) the ROFR Asset(s) subject to the Parent Acquisition Proposal, (iii) the purchase price offered by such Proposed Transferee (the “Parent Offer
Price”), (iv) reasonable detail concerning any non-cash portion of the proposed consideration, if any, to allow the General Partner to reasonably determine the fair value of such non-cash consideration, (v) Parent’s
estimate of the fair value of any non-cash consideration, and (vi) all other material terms and conditions of the Parent Acquisition Proposal that are then known to Parent. To the extent the Proposed Transferee’s offer consists of
consideration other than cash (or in addition to cash) the Parent Offer Price shall be deemed equal to the amount of any such cash plus the fair value of such non-cash consideration. No later than 45 days after Parent’s delivery of the Parent
Disposition Notice (the “Partnership Acceptance Deadline”), the General Partner shall notify Parent in writing that either (i) the General Partner has elected, with the approval of the Conflicts Committee, not to cause a
Partnership Group Member to purchase the applicable ROFR Assets on the terms set forth in the Parent Disposition Notice, in which case the Parent Entities may own, operate or Transfer the applicable ROFR Assets without any further obligation to
offer such ROFR Assets to the Partnership, other than any re-offer of the same ROFR Assets pursuant to the terms set forth in this paragraph (b) below, or (ii) the General Partner has elected, with approval of the Conflicts Committee, to
cause a Partnership Group Member to purchase the applicable ROFR Assets on the terms set forth in the Parent Disposition Notice (subject to the proviso set forth in Section 5.1(b), including without limitation the requirement to pay the Parent
Offer Price). If the Transfer by the Parent Entity to the Proposed Transferee is not consummated in accordance with the terms of the Parent Acquisition Proposal within the later of (A) 180 days after the Partnership Acceptance Deadline,
and (B) 10 days after the satisfaction of all consent, governmental approval or filing requirements, if any, the Parent Acquisition Proposal shall be 
  

 17 

 deemed to lapse, and the Parent Entity may not Transfer any of the ROFR Assets described in the Parent Disposition Notice
without complying again with the provisions of this Article V if and to the extent then applicable. 
 (c) If requested by the
transferee Party, the transferor Party shall use commercially reasonable efforts to obtain financial statements with respect to any ROFR Assets Transferred pursuant to this Article V as required under Regulation S-X promulgated by the Securities and
Exchange Commission or any successor statute. The Parent Entities and the Partnership Group shall cooperate in good faith in obtaining all necessary consents of equityholders, noteholders or other securityholders, governmental authorities, lenders
or other third parties.

interest at the Interest Rate from the date that payment is due until paid in full. Customer will pay all of Owner’s costs (including reasonable attorney’s fees and court costs) of collecting past due payments and late payment
charges, whether or not suit is brought.
 3.3 Customer will pay any and all taxes, fees or other charges and assessments imposed on the
Services, including sales or other excise taxes on the storage and throughput services. Customer will also pay any ad valorem or property ownership taxes, if any, on Customer’s Product located at the Terminals or in the Storage Tanks and

Storage Tank that Customer is otherwise ready, willing and able to deliver (a “Reduced Minimum Use Commitment Period”), then upon written notice by Customer to Owner, the Minimum Use Commitments will be reduced
proportionately during the Reduced Minimum Use Commitment Period, and Customer shall be entitled to receive a credit or refund to the extent the payments made by Customer in respect of the Reduced Minimum Use Commitment Period exceed the reduced
Minimum Use Commitments.
 Section 4. Operations, Receipts and Deliveries.
 4.1 Receipts and deliveries of Product will be handled within the normal business hours of the Terminals. Owner may, with Customer’s prior approval,
make temporary changes in the business hours of a Terminal or temporarily close any Terminal or Storage Tank because of an extraordinary event. Owner will notify Customer of such temporary changes or closure in advance, or as soon after
implementation as is practicable. Owner will not be responsible for the payment of any costs incurred by Customer or its transportation carrier for any delay in receiving or delivering Product or any other costs or fees, except to the extent
such delays are attributable to Owner’s inability to provide the Services other than an event of Force Majeure covered by Section 10 hereof.
 4.2 Customer must arrange for and pay all Third Party costs related to the delivery of Customer’s Product to the Terminals and from the Storage Tanks. Owner is not responsible for such Third Party costs. Unless
otherwise provided by Owner in writing, Customer must provide notice reasonably acceptable to Owner containing all necessary instructions, including without limitation, the identity and quantity and any other specifications of the Product and the
tentative date of delivery to the Terminals (the “Scheduling Notice”). Each Scheduling Notice delivered hereunder by Customer for deliveries of Product to a Terminal shall be sent to those individuals that Owner has specified
to Owner to receive such Scheduling Notice for the applicable Terminal with respect to such Product delivery. 
 4.3 Subject to the
restrictions of Attachment “A”, Owner will deliver to Customer, or to such Third Parties as Customer may direct, the Product held by Owner in the Storage Tanks for the account of Customer. Customer is responsible for providing
to Owner documentation required to authorize deliveries for or on its behalf from the Storage Tanks.
  

 5 

 4.4 Owner will provide the Services to Customer only with respect to Product. Customer will have access
to the Terminals and Storage Tanks for other products only with prior written notice to and consent by Owner. Any other product approved by Owner will then become part of “Product” as defined in this Agreement. If a
special method of providing the Services is required for Product, then Customer must notify Owner in sufficient time to enable Owner to consider whether, in Owner’s sole discretion, it will accept the proposed changes in the method of
delivering the Services and to take the necessary preparatory measures if it agrees with such changes. Absent such notice and absent Owner’s written approval with respect to changes in the Product or the method of delivering the Services,
Owner will not be liable for losses or damage incurred during the terminalling and storage of Product (except for losses and damages resulting from Product Loss), nor will Owner be obligated to provide such special Service. It is understood that the
cost of any additional or special equipment required by Customer or of alterations made necessary by the nature of Product will be for the account of Customer, and Customer will be responsible for the expense of any necessary cleaning and
restoration to their previous condition of the Terminals and Storage Tanks, including, without limitation, pumps, and loading facilities, unless otherwise explicitly stated in this Agreement. All fixtures, equipment and appurtenances attached
to the Storage Tanks will be installed by the Owner and will remain the property of Owner.
 4.5 Upon a change in the Product to be
terminalled and stored during the Term of this Agreement, or upon termination of this Agreement, Customer shall remove all liquid Product from the Terminals and Storage Tanks that can be safely pumped with existing equipment. Customer shall have a
reasonable amount of time to remove all liquid Product from the Terminals and Storage Tanks. Customer agrees to reimburse Owner for the actual costs of such removal, plus a ten percent (10%) administrative fee, should Customer fail to
remove its liquid Product within a reasonable time period. 
 4.6 If any Governmental Authority requires installation of any improvement,
alteration or addition to any Terminal or Storage Tank for purposes of compliance with Applicable Law, and if the installation would require Owner to make substantial and unanticipated capital expenditures, other than continued maintenance and
capital expenditures not affected by such requirement, Owner will be entitled to impose a reasonable service surcharge (which surcharge may include the Owner’s cost of capital) in addition to the fees set out in Attachment “A”.
Owner will notify Customer of (i) the cost of making any such improvement, alteration or addition, after Owner’s efforts to mitigate such costs, (ii) when such improvement, alteration or addition must be completed and (iii) the
Owner’s reasonable estimate of the service surcharge related to the capital expenditure to be paid by Customer over the remaining Term. Owner will not be required to make any improvements, alterations or additions to the Terminals or the
Storage Tanks in such circumstance, unless Customer agrees to pay the surcharge. If Customer elects, after negotiation with Owner in good faith, not to pay the surcharge and the Owner chooses not to pay for such improvement, alteration or
addition, Owner may direct the affected Product to a mutually acceptable Storage Tank at the same Terminal, another Terminal or at other facilities owned by Owner or its Affiliates. If Customer elects not to pay the surcharge, and if Owner does not
direct the Product to mutually acceptable alternate facilities, either Party may terminate this Agreement as to the Services provided at the affected Terminals and/or Storage Tanks from this Agreement, with an equivalent reduction of the fees set
out on Attachment “A”, including the Minimum Use Commitments, by giving the other Party notice of its intention no later than thirty (30) days after Owner’s receipt of notice of Customer’s election not to pay the
service surcharge. If Customer elects to pay the service surcharge, Owner shall proceed with the installation of the required improvement, alteration or addition. Owner will calculate the surcharge required to recover the portion of
Owner’s costs for the improvement, alteration or addition attributable to Customer’s use of the impacted portion of the Terminals and/or Storage Tanks. The portion of Owner’s costs to be recovered through the surcharge to Customer
shall equal the percentage of total revenues from the impacted segment of the Terminals and/or Storage Tanks attributable to Customer’s use of such Terminal or Storage Tank segment for the six (6) full Months preceding the date of
Owner’s notice to Customer of the cost of the improvement, alteration or addition. 
  

 6 

 Customer may pay the surcharge in equal monthly installments over the remaining Term. In such a case, the amount of
the monthly installment will be increased by an interest component calculated on the surcharge at a rate of 1% over the prime lending rate as reported in the Wall Street Journal on the date of completion of such installation. Within thirty
(30) days after completion of the required improvement, addition or alteration, Customer may elect to pay the surcharge for the remaining Term in one lump sum. Owner shall calculate the cost of the improvement, alteration or addition and the
surcharge using reasonable assumptions and estimates. In addition to actual capital and installation costs, the costs to be recovered through the surcharge will include engineering and interest expense (at a rate of 1% over the prime lending rate as
reported in the Wall Street Journal on the date of completion of such installation) and subsequent reasonable expenses, if any, of operating or maintaining such installation as reasonably determined by Owner. 
 4.7 When the Product is specifically identified and kept separate from the product of other customers (“Segregated Service”),
Customer will be responsible for providing all tank bottoms and in all other cases, Customer will be responsible for providing its proportional share of tank bottoms. Customer will retain ownership of any portion or all of the tank bottoms it
provides. 
 Section 5. Product Quality Standards and Requirements.
 5.1 Customer warrants to Owner that all Product tendered by or for the account of Customer for receipt into the Terminals and Storage Tanks will conform
to the specifications for such Product set forth in Attachment “B”, attached to this Agreement and included in it for all purposes by this reference, and will comply with industry standards and all Applicable Law. Owner may
rely upon the specifications and representations of Customer, if any, set forth in the Scheduling Notice described in Section 4.2 as to Product quality. Owner will not be obligated to receive Product into the Terminals and Storage
Tanks that is contaminated or that otherwise fails to meet the specifications set forth on Attachment “B”, nor will Owner be obligated to accept Product that fails to meet Product grade, if any, set forth in the Scheduling Notice.
Should Owner remove or dispose of or otherwise treat the Product for any water or other material or contaminants in or associated with the Product at any time, Customer shall pay or reimburse all costs and expense associated with such removal,
disposal or treatment.
 5.2 The quality of Product tendered into the Terminals and Storage Tanks for Customer’s account may be verified
either by Customer’s laboratory analysis, or by an Independent Inspector’s analysis indicating that the Product so tendered meets minimum Product specifications, if any, set forth in the Scheduling Notice. Such analysis may be
conducted on a periodic basis in accordance with a quality compliance program implemented by Customer, which program shall be subject to the approval of Owner, which approval shall not be unreasonably withheld. All costs associated with such
compliance program shall be borne by Customer. Upon reasonable notice to Customer, Owner, at its expense, may sample any Product tendered to Owner for Customer’s account for the purpose of confirming the accuracy of the
analysis.
 5.3 Unless Owner has provided Segregated Service for the Product, Owner may commingle fungible Products received from or on
behalf of Customer with those fungible products of other Third Parties using the Storage Tanks. Each Party may at all reasonable times conduct appropriate tests to determine whether Product meets the applicable specifications set forth in the
Scheduling Notice. Owner will be liable to Customer by reason of contamination of Product occurring at the Terminals or in the Storage Tanks that causes the Product to fail to meet specifications, but only to the extent such contamination
involves a Product Loss. In all other cases, Customer shall indemnify Owner for any Liability incurred by Owner to parties who purchase Product from Customer. 
  

 7 

 Section 6. Title and Custody of Product.
 6.1 Title to the Product will remain with Customer at all times subject to any lien in favor of Owner created pursuant to the terms of this Agreement or
under Applicable Law. Owner will assume custody of the Product beginning when such Product passes the flange connection between the rail car, barge, ship, or vehicle and Owner’s receiving hose at the Terminals and custody will pass back to
Customer at the time such Product passes the outlet flange of each Storage Tank. 
 6.2 Owner shall indemnify Customer for damages, losses,
or injury caused by Owner’s gross negligence or intentional misconduct. Owner shall otherwise have no responsibility for any loss, damage or injury to persons or property (including the Product) arising out of possession or use of the Product,
except to the extent that such loss, damage or injury involves a Product Loss. Customer shall indemnify Owner for any Liability incurred by Owner to Third Parties arising out of Owner’s possession or use of the Product for which Owner is not
liable under this paragraph and for any Liability to Third Parties arising out of or pertaining to the Product before its delivery by Customer to the Terminals and after its receipt by Customer from the Storage Tanks. 
 Section 7. Limitation of Liability and Damages.
 7.1 The maximum Liability of Owner for Product Loss will not exceed, and is strictly limited to, the market value of the Product at the time of the Product Loss or immediately prior to its contamination, plus the costs and expenses
actually, reasonably and necessarily incurred by Customer or Customer’s immediate purchaser in damage to equipment into which such Product was delivered from the Storage Tanks, plus any fines and penalties actually levied or imposed by anyone
including federal, state or local governments against Customer or Customer’s immediate purchaser by reason of such fault on Owner’s part. Owner may, in lieu of payment for Product, replace such Product with Product of like grade and
quality.
 7.2 EXCEPT FOR THE PARTIES’ INDEMNIFICATION OBLIGATIONS WITH RESPECT TO CLAIMS OF THIRD PARTIES, AND EXCEPT FOR
CUSTOMER’S MINIMUM USE COMMITMENTS, THE PARTIES’ LIABILITY FOR DAMAGES HEREUNDER IS LIMITED TO DIRECT, ACTUAL DAMAGES ONLY, AND NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR SPECIFIC PERFORMANCE, LOST PROFITS OR OTHER BUSINESS
INTERRUPTION DAMAGES, OR SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES, IN TORT, CONTRACT OR OTHERWISE, OF ANY KIND, ARISING OUT OF OR IN ANY WAY CONNECTED WITH THE PERFORMANCE, THE SUSPENSION OF PERFORMANCE, THE
FAILURE TO PERFORM, OR THE TERMINATION OF THIS AGREEMENT. EACH PARTY ACKNOWLEDGES ITS DUTY TO MITIGATE DAMAGES HEREUNDER.
 Section 8.
Product Measurement.
 8.1 Quantities of Product delivered to the Terminals and redelivered from the Storage Tanks shall be
determined for deliveries and receipts by truck, rail, ship and barge volumes and shall be measured by one of the following methods: meter, scale weights, bills of lading, barge and ship gauges or terminal tank gauges. Absent fraud or manifest
error, the quantities of Product in the Storage Tanks at any time will be determined from inventory records of receipts and deliveries. Unless indicated otherwise, quantity determinations will be based on a Barrel or Ton of Product and shall be
determined in accordance with the latest established API/ASTM standards for the method of delivery. Gauging of Product received, delivered and in storage will be taken jointly by representatives of the Parties; provided, that if Customer does not
have representatives present for gauging, Owner’s gauging will be conclusive, absent fraud or manifest error. Customer may use an Independent Inspector at its own expense.
  

 8 

 8.2 Storage Tank meters and gauges will be calibrated periodically and after each completion of a repair
or replacement of a meter. Such repairs and replacements shall be at Owner’s expense. Such calibration shall be in accordance with the latest applicable API/ASTM standards. If a meter or gauge is determined by either Party to be
defective or inoperative, such Party shall immediately notify the other Party, and it will be the responsibility of the Owner to promptly make repairs or replacements. In the event that Product was received into Storage Tanks having a faulty
meter or gauge, the Parties will determine the correct volume of Product received. If the Parties are unable to determine and agree on the correct volume of Product received, they will appoint a mutually acceptable Independent Inspector to determine
the correct quantity, and the findings of the Independent Inspector shall be final and binding on the Parties except for fraud or manifest error. The Parties shall share equally the cost of the Independent Inspector under this
Section 8.2.
 Section 9. Product Loss and Product Gain.
 9.1 During such time as Owner has custody of the Product pursuant to Section 6, Owner will indemnify Customer against, and is responsible for,
any Product Loss that occurs while the Product is located at the Terminals or remains in the Storage Tanks. In the event of the foregoing Product Losses, the total Barrels of net Product Loss each calendar quarter will be determined and will be
replaced by Owner, or Owner will reimburse Customer the cost of such Product. 
 9.2 Each calendar quarter, Owner will use the measurement
procedures set out in Section 8 to determine the net gain or loss of Product in the Storage Tanks, excluding any loss resulting in Product Loss. Owner shall not be liable for any net loss (other than Product Loss) and may retain any
net gain during the Term of this Agreement. 
 Section 10. Force Majeure.
 10.1 If either Party is unable to perform or is delayed in performing, wholly or in part, its obligations under this Agreement, other than the obligation
to pay funds when due, as a result of an event of Force Majeure, that Party may be excused from such performance by giving the other Party prompt written notice of any event that is or could become an event of Force Majeure with reasonably full
particulars thereof. The obligations of the Party giving notice, so far as such obligations are affected by the event of Force Majeure, will be suspended during, but not longer than, the continuance of the event of Force Majeure beginning with
the time that the event first occurs. The affected Party must act with commercially reasonable diligence to overcome or remedy the event of Force Majeure and resume performance as quickly as possible. Once the event of Force Majeure is remedied, the
affected Party shall notify the other Party that the event of Force Majeure no longer affects such obligations. If Owner is excused from providing service pursuant to this Agreement due to an event of Force Majeure, the fees hereunder, not
already due and payable, and the Minimum Use Commitments, if any, that are directly affected by such Force Majeure event will be excused or proportionately reduced, on a daily basis, for so long as the Owner’s performance is excused due to the
event of Force Majeure.
 10.2 The requirement that any Force Majeure event be remedied with all reasonable diligence shall not require the
settlement of strikes, lockouts, or other labor difficulty by the Party claiming excuse due to an event of Force Majeure contrary to its wishes.
 10.3 If either Party is rendered unable to perform by reason of an event of Force Majeure for a period in excess of one year, then either Party may terminate this Agreement with respect to the portion of the Terminals and the Storage Tanks
affected by such Force Majeure event upon written notice to the other Party.

 Section 11. Inspection of and Access to the Storage Tanks.
 11.1 Customer shall have the right during Owner’s normal business hours and after reasonable notice to Owner so as not to disrupt the operations of
the Terminals or the Storage Tanks or Owner’s other operations (i) to make periodic operational inspections of the Terminals and Storage Tanks, (ii) to conduct audits of any pertinent books and records, including those related to
receipts, deliveries and inventories of Product, and (iii) to conduct physical verifications of the amount of Product delivered to the Terminals and stored in the Storage Tanks. Customer’s right and that of its authorized
representatives to inspect the Terminals and Storage Tanks will be exercised by Customer in a way that will not interfere with or diminish Owner’s control over or its operation of the Terminals or Storage Tanks and will be subject to reasonable
rules and regulations promulgated by Owner.
 11.2 Customer acknowledges that any grant of the right of access to the Terminals and
Storage Tanks under this Agreement or under any document related to this Agreement is a grant of a license only and shall convey no interest in or to the Terminals or Storage Tanks or any part of it, and may be withdrawn by Owner at its discretion
at any time.
 Section 12. Assignment.
 This Agreement shall be binding upon and shall inure to the benefit of the successors and assigns of Owner. Customer covenants that it will not by operation of law or otherwise assign, hypothecate, pledge, encumber or mortgage this
Agreement, or any part of or right or obligation under it, without the prior written consent of Owner in each instance; provided, however, (i) Customer shall be allowed to pledge and hypothecate its interest hereunder to the lenders under its
credit facilities and (ii) Owner recognizes that the Customer intends to contract with Third Parties related to the storage and terminalling of Product which will require the use of the Owner’s services, and the foregoing limitation shall
not prevent such activities, but in no event shall such activities give any Third Party any rights against Owner, and the Third Parties shall look solely to Customer for performance. For purposes of this Section, “assign” will be
considered to include any change in the majority ownership or control of Customer or Owner, as applciable. The foregoing limitation on the right to assign is intended to be not only a covenant but a full and absolute withholding of the power
and authority to assign, transfer, hypothecate, encumber or mortgage this Agreement, and any attempt by Customer to assign, transfer, hypothecate, encumber or mortgage this Agreement will be null and void and need not be recognized by Owner for any
purpose. Owner may, however, ignore any such attempt to assign, transfer, hypothecate, encumber or mortgage this Agreement and may continue to deal with Customer as if such attempt had never been made and continue to look to and demand of Customer
full performance of all terms, conditions and provisions of this Agreement, including the Minimum Use Commitment. The consent by Owner to any assignment, hypothecation, pledge, encumbrance, mortgage or use of this Agreement will not constitute a
waiver of Owner’s right to withhold its consent to any other or further assignment, hypothecation, pledge, encumbrance, mortgage or use of the Agreement. The absolute and unconditional prohibitions contained in this Section and
Customer’s agreement to them are material inducements to Owner to enter into this Agreement, and any breach of them will constitute a material default under this Agreement permitting Owner to exercise all remedies provided for in this Agreement
or by law.
 Notwithstanding anything hereinabove to the contrary, Owner shall be permitted to sell or otherwise transfer all or part of the
Terminals and Storage Tanks to an Affiliate, whether by sale or by operation of law, provided, such Affiliate agrees to be bound the terms and conditions of this Agreement with respect to the Terminals and Storage Tanks transferred to it. Owner
shall likewise be permitted to 
  

 10 

 sell or otherwise transfer all or part of the Terminals or the Storage Tanks to a non-Affiliate, provided, such
non-Affiliate agrees to be bound the terms and conditions of this Agreement with respect to the Terminals and Storage Tanks transferred to it, provided, further, that such sale or transfer to a non-Affiliate shall not be permitted if (i) such
sale or transfer would have a material adverse effect on the transactions contemplated under this Agreement or (ii) such sale or transfer is made to a Third Party that Customer reasonably deems to be unacceptable based upon a review of such
Third Party’s creditworthiness, financial capabilities, and ability to operate the Terminals and Storage Tanks. Owner shall give Customer written notice of any proposed sale or other transfer at least sixty (60) days prior to the sale or
other transfer and, in the case of a transfer to a Third Party, shall set out the name and sufficient background information about the proposed transferee to allow the Customer to reasonably determine whether the transfer would have a material
adverse effect on the transactions under the Agreement. Customer will, before the end of the sixty (60) days, deliver its written consent to the transfer to Owner, not to be unreasonably withheld, or else give notice of its objection to the
transfer and the reason or reasons for its objection. 
 Section 13. Notice.
 Any notice required under this Agreement must be in writing and will be deemed received when actually received and delivered by (i) United States
mail, certified or registered, return receipt requested, (ii) confirmed overnight courier service, or (iii) confirmed facsimile transmission properly addressed or transmitted to the address of the Party indicated in Attachment
“A” or to such other address or facsimile number as one Party shall provide to the other Party in accordance with this provision. Unless provided otherwise herein, all statements, payments and other documents to be delivered pursuant
to this Agreement shall also be delivered to the address of the Party indicated in Attachment “A”.
 Section 14. Compliance with
Law and Safety.
 14.1 Customer warrants that the Product tendered by it has been produced, transported and handled in full compliance
with all Applicable Law. Owner warrants that the services provided by it under this Agreement are in full compliance with all Applicable Law. Each Party also warrants that it may lawfully receive and handle the Product, and it will furnish to
the other Party any evidence required to provide compliance with Applicable Law and to file with applicable Governmental Authorities reports evidencing such compliance with Applicable Law.
 14.2 Customer will furnish Owner with information (including material safety data sheets) concerning the safety and health aspects of the Product
terminalled or stored under this Agreement. Owner will communicate such information to all persons who may be exposed to or may handle such Product, including without limitation, Owner’s agents and contractors.
 Section 15. Default, Waiver and Remedies.
 15.1 The occurrence of any of the following events shall constitute an “Event of Default” hereunder:
 (a)
either Party fails to pay any sum owed by it to the other Party under this Agreement within fifteen (15) Business Days of the delivery to the defaulting Party of a notice of default;
 (b) either Party fails to satisfy any obligation or render any performance to the other Party or breaches any covenant made to the Party under this
Agreement, which breach of obligation, performance or covenant, if capable of being cured, is not cured to the reasonable satisfaction of the other Party within fifteen (15) Business Days from the date that such Party receives notice that
corrective action is needed;
  

 11 

 (c) either Party files a petition in bankruptcy or otherwise becomes subject to the jurisdiction of a
bankruptcy court;
 (d) either Party to this Agreement shall repudiate, deny or disaffirm its obligations under this Agreement;
 (e) this Agreement is cancelled, terminated, revoked or rescinded without the express prior consent of the other Party (except for a termination under
Section 10.3 hereof), or any proceeding shall have been commenced by any person (other than either Party) seeking to cancel, revoke, rescind or disaffirm the obligations of any Party to this Agreement (unless such Party is contesting the
proceeding in good faith and such proceeding is withdrawn or dismissed with prejudice within 15 days); or 
 (f) the failure to provide an
assurance of future performance under Section 17.2. 
 15.2 The waiver by the non-defaulting Party of any right under this
Agreement will not operate to waive any other such right nor operate as waiver of that right at any future date upon another default by either Party under this Agreement, and a single or partial exercise of any right, power or privilege by one Party
in the event of the other Party’s default will not preclude any subsequent or further exercise of that right, power, or privilege or the exercise of any other right, power, or privilege. Nothing in this Section 15.2 is intended
in any way to limit or prejudice any other rights or remedies the non-defaulting Party may have under this Agreement, under Applicable Law or in equity. The remedies provided in this Agreement are not exclusive and, except as otherwise
expressly limited by this Agreement, are in addition to all other remedies of the non-defaulting Party at law or in equity. Acceptance by Owner of any payment from Customer for any charge or service after termination of this Agreement shall not
be deemed a renewal of this Agreement under any circumstances. Notwithstanding any provision in this Agreement to the contrary, if Customer is not then in default, Customer shall be entitled to remove its Product from the Terminals and Storage
Tanks at any time if Owner is in default under this Agreement.
 15.3 Upon the occurrence and during the continuance of an Event of Default,
and at any time thereafter, the non-defaulting Party may, by delivery of written notice to the defaulting Party, take any or all of the following actions, without prejudice to the rights of the non-defaulting Party to enforce its claims against the
defaulting Party and to enforce any other remedies provided by law: (a) withhold or suspend its performance under this Agreement without prior notice; (b) immediately terminate this Agreement in whole or in part; and (c) enforce
any and all rights and interests created and existing under this Agreement or arising under Applicable Law, including, without limitation, all rights and remedies existing under any security documents and all rights of setoff. The enumeration
of the foregoing rights is not intended to be exhaustive and the exercise of any right shall not preclude the exercise of any other rights, all of which shall be cumulative.
 Section 16. Insurance.
 16.1 Workers’ Compensation Insurance. At all times
during the term of this Agreement, each Party shall carry and maintain in force, workers’ compensation insurance, with policy limits equal to or greater than the statutory requirements of the states in which the Storage Tanks are located and
employers’ liability insurance with policy limits equal to or greater than $3,000,000 for each accident, $3,000,000 for each employee and $3,000,000 as to each disease. In the event either Party leases employees, then lessee Party shall cause
lessor Party to carry workers’ compensation and/or employer’s liability insurance at the levels set forth above. 
  

 12 

 16.2 General Liability Insurance. At all times during the term of this Agreement, each Party shall
carry and maintain in force, comprehensive general liability insurance, with a minimum $3,000,000 combined single limit. The Owner’s commercial general liability insurance shall include coverage for Product Loss for Product in the care, custody
and control of Owner and shall cover “sudden and accidental pollution” events. 
 16.3 Automobile and Truck Insurance. At
all times during the term of this agreement, each Party shall carry and maintain in force, commercial automobile liability insurance with a minimum $3,000,000 combined single limit per occurrence for owned, hired and non-owned automotive equipment.

– Truckers, or an endorsement that offers similar or greater coverage. 
 16.4 Customer’s Product Insurance. Insurance on
Customer’s Product, if any, that may be desired by Customer, shall be carried by Customer at Customer’s expense. Should Customer elect to carry Product insurance, then each policy of insurance shall be endorsed to provide a waiver of
subrogation rights in favor of Owner and its affiliates. 
 16.5 Miscellaneous Insurance Provisions. 
 (a) The above stipulated levels of insurance coverage may be satisfied through primary insurance or a combination of primary and excess or umbrella
liability insurance. 
 (b) Either Party may elect to self-insure for the coverages required by this Section 16 upon written
approval by other Party. 
 (c) Either Party may elect deductibles to the coverages required by this Section 16 upon the written
approval by other Party. 
 (d) The mere purchase and existence of insurance coverage shall not reduce or release either Party from any
liabilities incurred or assumed under this Agreement. 
 Section 17. Security and Credit. 
 17.1 If Customer fails to pay the sums owed by it to Owner pursuant to this Agreement when due, Owner shall provide Customer with notice of default as
provided in this Agreement and an opportunity to cure such default within a period of fifteen (15) days from delivery of such notice. If Customer has not cured such default within such fifteen (15) day cure period, Owner may exercise
any of the remedies provided in Section 15.3 or proceed in accordance with Applicable Law to recover its damages, including, without limitation, all costs, reasonable attorney fees, and expenses incurred by Owner in the recovery of fees
owed to Owner by Customer.
 17.2 If at any time Owner believes in good faith that the ability of the Customer to perform under this
Agreement has been impaired or is unsatisfactory, advance cash payment or other assurance of future performance acceptable to Owner, including letters of credit, will be given by Customer upon demand by Owner to cover fees that are reasonably
anticipated to become due under this Agreement over the remaining Term. Failure to provide an assurance of future performance pursuant to this paragraph shall be deemed an Event of Default under Section 15.1. 
  

 13 

 17.3 If any insolvency, bankruptcy, receivership, or similar proceedings are initiated by or against
Customer, on the day immediately before such event, any fees for services rendered or to be rendered under this Agreement and any fees required to be paid for the remaining Term of this Agreement, will become immediately due and payable, and this
Agreement will terminate, without prejudice to any other rights or remedies it may have under this Agreement or the law. 
 Section 18.
Indemnity.
 18.1 Indemnity. Subject to Section 7, each Party (the “Indemnifying
Party”) shall indemnify and hold the other Party, its Affiliates, and their employees, directors, officers, representatives, agents and contractors (collectively, the “Indemnified Party”) harmless from and
against any and all Liabilities arising from the Indemnifying Party’s (i) breach of this Agreement, (ii) gross negligence or willful misconduct of it, its Affiliates and their employees, directors, officers, representatives, agents or
contractors in connection with the performance of such Party’s obligations under this Agreement, or (iii) failure to comply with Applicable Law with respect to the sale, transportation, storage, handling or disposal of the Product, unless
and to such extent that such Liability results from the Indemnified Party’s breach of this Agreement, gross negligence or willful misconduct, or failure to comply with Applicable Law.
 18.2 No Third Party Rights. The Parties’ obligations to defend, indemnify and hold each other harmless under the terms of this Agreement
shall not vest any rights in or enforceable by any Third Party, whether a Governmental Authority or private entity, nor shall they be considered an admission of liability or responsibility for any purposes other than those enumerated in this
Agreement. The terms of this Agreement are enforceable only by the Parties, and no Third Party, including a member of Owner, shall have a separate right to enforce any provision of this Agreement, or to compel any Party to comply with the terms
of this Agreement.
 18.3 Notice. The Indemnified Party shall notify the Indemnifying Party as soon as practicable after
receiving notice of any claim or proceeding brought against it that might give rise to an indemnity claim under this Agreement (a “Third Party Claim”) and shall furnish to the Indemnifying Party the complete details within
its knowledge. Any delay or failure by the Indemnified Party to give notice to the Indemnifying Party shall not relieve the Indemnifying Party of its obligations except to the extent, if any, that the Indemnifying Party shall have been
materially prejudiced by reason of such delay or failure.
 18.4 Claims. The Indemnifying Party shall have the right to assume
the defense, at its own expense and by its own counsel, of any Third Party Claim; provided, however, that such counsel is reasonably acceptable to the Indemnified Party. Notwithstanding the Indemnifying Party’s appointment of counsel to
represent an Indemnified Party, the Indemnified Party shall have the right to employ separate counsel reasonably acceptable to the Indemnifying Party, and the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate
counsel if in the Indemnified Party’s reasonable judgment (i) the use of counsel chosen by the Indemnifying Party to represent the Indemnified Party would present such counsel with a conflict of interest or defenses are available to the
Indemnified Party that are not available to the Indemnifying Party (ii) the Indemnifying Party shall not have employed counsel to represent the Indemnified Party within a reasonable time after notice of the institution of such Third Party
Claim. If requested by the Indemnifying Party, the Indemnified Party agrees to reasonably cooperate with the Indemnifying Party and its counsel in contesting any claim or proceeding that the Indemnifying Party defends, including, if
appropriate, making any counterclaim or cross-complaint. All reasonably incurred costs and expenses incurred in connection with the Indemnified Party’s cooperation shall be borne by the Indemnifying Party.
  

 14 

 18.5 Settlement. No Third Party Claim may be settled or compromised by (i) the
Indemnified Party without the consent of the Indemnifying Party or (ii) by the Indemnifying Party without the consent of the Indemnified Party. Notwithstanding the foregoing, an Indemnifying Party shall not be entitled to assume
responsibility for and control of any proceeding if such proceeding involves an Event of Default by the Indemnifying Party under this Agreement which shall have occurred and be continuing.
 Section 19. Construction of Agreement.
 19.1 Headings. The headings of the sections and subsections of this Agreement are for convenience only and shall not be used in the interpretation of this Agreement.
 19.2 Amendment or Waiver. This Agreement may not be amended, modified or waived except by written instrument executed by officers or duly
authorized representatives of the respective Parties.
 19.3 Severability. Any provision of this Agreement that is prohibited or
not enforceable in any jurisdiction shall, as to that jurisdiction, be ineffective only to the extent of the prohibition or lack of enforceability without invalidating the remaining provisions of this Agreement, or affect the validity or
enforceability of those provisions in another jurisdiction or the validity or enforceability of this Agreement as a whole.
 19.4 Entire
Agreement and Conflict with Attachments. This Agreement (including Attachments) contains the entire and exclusive agreement between the Parties with respect to the subject matter hereof, and there are no other promises, representations, or
warranties affecting it. The terms of this Agreement may not be contradicted, explained or supplanted by any usage of trade, course of dealing or course of performance and any other representation, promise, statement or warranty made by either
Party or their agents that differs in any way from the terms contained herein will be given no force or effect. In the case of any conflict between the body of this Agreement and any of its Attachments, the terms contained in the Attachments
will govern.
 19.5 Law. This Agreement will be construed and governed by the laws of the State of Oklahoma except the choice of law
rules of that State that may require the application of the laws of another jurisdiction.
 19.6 Counterparts. This Agreement may
be executed in any number of counterparts with the same effect as if all signatory Parties had signed the same document. All counterparts shall be construed together and shall constitute one and the same instrument. 
 19.7 Further Assurances. Subject to the terms and conditions of this Agreement, each of the Parties hereto will use commercially reasonable
efforts to take, or cause to be taken, all action, and to do, or cause to be done, all things necessary under applicable laws and regulations to consummate the transactions contemplated by this Agreement. 
 19.8 No Third-Party Beneficiaries. Nothing contained in this Agreement, expressed or implied, is intended or shall be construed to confer upon or
give to any Person (including any limited partners of SemGroup Energy Partners, L.P.) other than the Parties hereto and their successors or permitted assigns, any rights or remedies under or by reason of this Agreement.

	3.	Fees for Storage and Terminalling Services; Reimbursement of Energy Costs 

  

	 	(a)	Storage Service Fees: 

 Minimum Use
Fee: Customer is required to use or pay for storage services on 5,000,000 Barrels per month (“Minimum Storage Commitment”) at charge of $** per Barrel per month (“Base Storage Charge”). The
determination of the number of Barrels stored per month shall be calculated based on the average Barrels stored per day according to Owner’s month end perpetual inventory records (as adjusted by Owner for any physical inventory counts taken).
The Minimum Storage Commitment fees will be payable in full, in cash, on a monthly basis (unless the failure to achieve the Minimum Storage Commitment results from Owner’s inability or failure to provide the services, as specified in this
Agreement). Should the initial month under this Agreement be less than a full month, the Minimum Storage Commitment for that month shall be proportionately reduced to reflect the actual time period. 
 Fees for Additional Storage: To the extent that the number of barrels stored on behalf of Customer exceeds the Minimum Storage Commitment set
forth above in any given Month, Customer shall pay for such services an amount equal to 110% of the Base Storage Charge per Barrel for such excess barrels. This charge will be invoiced and will be payable monthly. 
  

	 	(b)	Terminalling Fees: 

 Minimum Use Fee:
“Throughput” means, for any period, the aggregate quantity of Product moved through Owner’s Storage Tanks on behalf of Customer under this Agreement and such quantity shall be calculated based upon the total quantity of asphalt
products shipped and/ or sold by Customer from the facilities where the Storage Tanks are located with such quantity of asphalt products converted to base asphalt cement Tons based upon agreed to formulas between Owner and Customer. Customer is
required to use or pay for throughput services on ** Tons per calendar quarter (“Minimum Throughput Commitment”) at a charge of $** per Ton. The Minimum Throughput Commitment fees per calendar quarter will be payable in
advance, in full, in cash, on a monthly basis in

 Attachment A-1 

 three equal payments (unless the failure to achieve the Minimum Throughput Commitment results from
Owner’s inability or failure to provide the services, as specified in the Agreement). Should the initial calendar quarter under this Agreement be less than a full calendar quarter, the Minimum Throughput Commitment for that quarter shall
be proportionately reduced to reflect the actual time period. 
 Fees for Additional Throughput: If throughput in any calendar quarter
during the term hereof exceeds the Minimum Throughput Commitment, then Customer shall pay for such services at a charge of $** per Ton for such excess Tons. This charge will be invoiced in the final month of a calendar quarter. 
  

	 	(c)	CPI Index Adjustments of Fees: 

 The fees set forth
in paragraphs (a) and (b) above will be subject to adjustment as of the first day of July of each year beginning on July 1, 2009. The fee then in effect will be adjusted by the percentage increase or decrease in the Consumer Price
Index- All Urban Consumers for the last calendar year compared to the immediately preceding calendar year as published by the United States Department of Labor, Bureau of Labor Statistics, or any other successor or substitute agency or authority;
provided, however, no fee, as adjusted, will ever be less than the original amount of said fee set forth in this Attachment “A”. 
  

	 	(d)	Reimbursement of Energy Costs: 

 Customer shall
reimburse Owner for all direct energy costs (e.g., electricity, natural gas, steam) attributable to the services provided hereunder. Direct energy costs will be based upon usage as determined by metering equipment that serves the facility where the
Storage Tanks are located. Energy costs will be invoiced monthly for the prior month’s energy usage. 
  

	4.	Operating Hours 

 24 Hours per day, 7 days per week.

  

	5.	Terminals 

 Terminals means (i) the asphalt
cement and residual fuel storage Terminals of Owner as listed in Attachment A-1 attached hereto, and as may be amended from time to time, and (ii) any asphalt cement or residual fuel storage terminals as are subsequently acquired or
constructed by the Owner to replace such existing asphalt cement and residual fuel storage terminals, provided, Terminals shall not include any of Customer’s asphalt manufacturing or processing facilities and equipment that are located
at any Terminal. 
  

	6.	Term 

 The initial term of this Agreement (the
“Initial Term”) begins on the Effective Date and ends December 31, 2014. At the end of the Initial Term, this Agreement will automatically extend for successive periods of one Contract Year each (each such period being
an “Extended Term”), unless either Party notifies the other at least twelve Months before the end of the Initial Term or the then-current Extended Term, if any, that it desires to terminate the Agreement effective at the end
of the Initial Term 
  
  

	**	Certain confidential information on this page has been omitted and filed separately with the Securities and Exchange Commission. 

 Attachment A-2 

 or the then current Extended Term, if any. The Initial Term together with all Extended Terms, if any, will be deemed the
“Term” of this Agreement. For a period of two (2) Calendar Years after the termination or expiration of this Agreement, Owner shall have a preferential right to match any bona fide Third Party offer for any storage or
throughput services provided to Customer on the same terms and conditions specified in the Third Party offer. Customer shall not be obligated to accept Owner’s offer to provide such services unless Owner agrees to provide the services to
Customer on the terms and conditions set forth in the Third Party offer.
