 Exhibit 10.3 

INTERIM INVESTORS AGREEMENT 

This Interim Investors Agreement (this “Agreement”) is made as of February 19, 2015, by and among Arc Terminals Joliet
Holdings LLC, a Delaware limited liability company (“Buyer”), Arc Logistics Partners LP, a Delaware limited partnership (“Arc”), and EFS-S LLC, a Delaware limited liability company (“GE”). Arc and
GE are each referred to herein as an “Investor” and collectively as the “Investors”. Capitalized terms used but not defined herein shall have the meanings given thereto in the Purchase Agreement (as defined below)
unless otherwise specified herein. 
 RECITALS 

1. On the date hereof, Buyer is entering into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with
Centerpoint Properties Trust, a Maryland real estate investment trust (“Seller”), pursuant to which Buyer has agreed to purchase from Seller all of the limited liability company interests of Joliet Bulk, Barge & Rail LLC, a
Delaware limited liability company (the “Company”) subject to the terms and conditions thereof (the “Transaction”). 

2. On the date hereof, Arc and Aircraft Services Corporation, a Nevada corporation (“ASC”), an affiliate of GE, are
simultaneously executing a letter agreement in favor of Buyer under which such parties have agreed, subject to the terms and conditions set forth therein, to make (either directly or indirectly) an equity investment in Buyer in connection with the
transactions contemplated by the Purchase Agreement (each, an “Equity Commitment Letter”, and, collectively, the “Equity Commitment Letters”), copies of which are attached as Exhibit A hereto. 

3. On the date hereof, a subsidiary of Arc is simultaneously causing to be delivered to Seller a letter of credit in support of certain
obligations of Buyer pursuant to the Purchase Agreement (the “Letter of Credit”), a copy of which is attached as Exhibit B hereto. 

4. The parties hereto wish to agree to certain terms and conditions that will govern the actions of Buyer and the relationship among the
Investors, including with respect to the Purchase Agreement, the Equity Commitment Letters, the Letter of Credit, and the transactions contemplated by each of the foregoing. 

Therefore, the parties hereto hereby agree as follows: 
  

	1.	AGREEMENTS AMONG THE INVESTORS. 

 1.1 Pre-Closing Decisions. 

1.1.1 All decisions to be made with respect to the following issues shall require the unanimous consent of the Investors in each
Investor’s sole discretion: (a) amending or modifying the Purchase Agreement or waiving any of Buyer’s rights thereunder, (b) waiving any of the conditions set forth in Article 8 of the Purchase Agreement (the “Closing
Conditions”), (c) enforcing any remedies of Buyer under the Purchase Agreement on account of or due to Seller’s breach or threatened breach of any of Seller’s representations, warranties or covenants made therein,
(d) determining that there has occurred a breach by Seller of its representations, warranties or covenants contained in the Purchase Agreement, (e) prior to Closing, except as set 

 
forth in Section 1.2 below or as contemplated by clause (f) of this Section 1.1.1, the negotiation or entry by Buyer into any contract, agreement, arrangement or understanding
(whether written or oral) other than agreements with respect to any regulatory filings contemplated by the Purchase Agreement, or (f) prior to Closing, the taking of any other action by Buyer, other than to prepare for and consummate, and to
negotiate, prepare, execute and deliver all documents, agreements, instruments and certificates as shall be necessary to consummate, the Transaction (and the other transactions contemplated by the Purchase Agreement) in a manner contemplated by the
Purchase Agreement. Notwithstanding anything to the contrary provided herein, Arc shall have sole authority and be solely responsible for (and GE will have no authority with respect to) making any and all decisions with respect to
(i) negotiating, entering into and borrowing under definitive agreements relating to any indebtedness to be provided to Arc or a subsidiary thereof in connection with Arc’s direct or indirect financing of the Transaction, including with
respect to the debt commitment letter attached as Exhibit C hereto (the “Debt Commitment Letter”) or (ii) negotiating, entering into and taking any and all actions with respect to the issuance and sale (in one or a
series of transactions) of any equity securities by Arc in connection with Arc’s direct or indirect financing of the Transaction (the “Arc Equity Offering”). 

1.1.2 Each Investor agrees that it will comply with, or shall cause its affiliate party thereto to comply with, the respective obligations
under such Investor’s Equity Commitment Letter and will also use its reasonable best efforts, subject to the terms and conditions in the Purchase Agreement, to cause the Buyer to comply with its obligations under the Purchase Agreement. 

1.1.3 Notwithstanding any provision of this Agreement to the contrary, from and after the time an Investor becomes a Failing Investor (as
defined below), the approval or consent of such Failing Investor shall not be required for any purposes under Section 1.1 or Section 1.3.1 of this Agreement. For the avoidance of doubt, any provision of Section 1.1 or
Section 1.3.1 that requires the consent or approval of the Investors shall be deemed to require only the consent or approval of the non-Failing Investor. 

1.2 Limited Liability Company Agreement. Each Investor agrees to negotiate in good faith with respect to the matters set forth on
Exhibit D and agrees to enter into (or cause a wholly-owned subsidiary thereof to enter into), concurrently with the Closing, one or more definitive agreements with respect to such matters; provided that such definitive agreements shall be
consistent with Exhibit D or, if inconsistent with Exhibit D, shall be approved by the unanimous consent of the Investors. 

1.3 Equity Commitments; Indemnification. 

1.3.1 Each Investor hereby acknowledges and agrees that it is bound by, or its affiliate is bound by, the respective provisions set forth in
each Equity Commitment Letter (each, a “Commitment”), in each case subject to the terms and conditions thereof, and that Buyer shall be entitled to enforce the provisions of each Equity Commitment Letter on the terms and conditions
set forth therein. Buyer shall not attempt to enforce either Equity Commitment Letter until (i) the Investors have unanimously determined the Closing Conditions and the other conditions set forth in the Equity Commitment Letters have been
satisfied or validly waived as permitted hereunder or (ii) a court of competent jurisdiction finally determines that Buyer is required to enforce the provisions of the Equity Commitment Letters pursuant to the terms of the Purchase Agreement.

  
 2 

 1.3.2 Notwithstanding anything to the contrary in this Agreement or the Equity Commitment
Letters, each Investor acknowledges and agrees that in the event of (x) such Investor’s breach in any material respect of its obligations under this Agreement, or its failure to fund, or cause its affiliate party thereto to fund, the
respective Commitment as and when required under the Equity Commitment Letters or (y) by reason of the final determination of a court of competent jurisdiction that Buyer breached the Purchase Agreement, and such breach by Buyer resulted from
such Investor individually causing the Closing to not occur (or otherwise preventing it from occurring) when Buyer was obligated to close the Transaction, such Investor (in the case of either clause (x) or (y), a “Failing
Investor”) shall be responsible for, and shall indemnify and hold harmless Buyer and the other Investor from and pay and reimburse Buyer and the other Investor for (in each case promptly upon demand), Seller drawing upon the Deposit Letter
of Credit and any and all other losses, liabilities, damages, judgments, settlements and expenses, including reasonable attorneys’ fees arising or resulting from such breach by the Failing Investor or Buyer (collectively,
“Losses”). To the extent that an Investor makes a determination, in its sole discretion, that one or more of the Closing Conditions have not been satisfied, the other Investor may, at such other Investor’s option, provide the
Investor making such determination and Buyer with a written irrevocable notice that it is prepared to fund, or cause its affiliate party thereto to fund, the respective Commitment under the Equity Commitment Letters (a “Funding
Notice”) and such Funding Notice shall serve as conclusive evidence, as among the Investors and Buyer, that the Investor providing the Funding Notice stood willing and ready to consummate the Transaction and fund its Commitment. No Investor
shall have any liability to Buyer or the other Investor by reason of exercising its rights to refuse to waive any Closing Condition that has not been satisfied prior to Closing or its correct determination that a Closing Condition to the obligations
of Buyer under the Purchase Agreement has not been fulfilled. 
 1.3.3 Notwithstanding anything to the contrary contained in this Agreement,
including Section 1.3.2 hereof, in the event that the Seller shall draw on all or any portion of the funds available to it under the Deposit Letter of Credit for any reason whatsoever (including on account of the receipt of notice from the
issuing bank that it will not renew the Deposit Letter of Credit, or otherwise), other than on account of the Closing having failed to occur as a result of Arc being a Failing Investor or the intentional and wrongful misconduct on the part of Arc
(or its affiliate that is not an Investor) to consummate the transactions contemplated by the Debt Commitment Letter or the Arc Equity Offering (or both), GE agrees that it shall reimburse Arc, promptly upon demand, for forty percent (40%) of
the amount drawn under such Deposit Letter of Credit; provided, however, that Arc shall reimburse GE for forty percent (40%) of any funds in respect of the Deposit Letter of Credit that are subsequently returned to or recovered by
Arc or Buyer promptly upon receipt of such returned or recovered funds.

 1.4 Expense Sharing. 

1.4.1 Arc will be responsible for sixty percent (60%) of and GE will be responsible for forty percent (40%) of all out-of pocket
expenses incurred in connection with the Transaction (including any due diligence investigation) by Buyer and each Investor (or their respective affiliates) prior to the Closing (or, in the case of expenses incurred by a Failing Investor, prior to
such Investor becoming a Failing Investor), including, without limitation, the reasonable fees, expenses and disbursements of lawyers, accountants, consultants and other advisors that may have been retained by Buyer or any Investor (or their
respective affiliates), as identified in a separate letter agreement entered into by Arc and GE on or prior to the date hereof (as such letter agreement may be amended or modified from time to time in writing by Arc and GE) (all such fees and
expenses, in the aggregate, the “Investor Expenses”). Notwithstanding the foregoing, if the Purchase Agreement is terminated, then the foregoing cost sharing provisions will cease to apply as to costs incurred thereafter unless
otherwise agreed by the Investors in writing. If the Transaction is consummated, then the Investors may jointly elect to have the Buyer pay such expenses instead of the Investors reimbursing each other, and if the Investors jointly make such
election, then each Investor shall make an equity contribution to the Buyer corresponding to its reimbursement obligation. 
 1.4.2 Prior to
making any payment of Investor Expenses hereunder of the other Investor, the paying Investor shall be entitled to receive and review reasonable documentation of such fees and expenses. Further, each Investor shall be entitled to receive and review
all work product relating to any due diligence investigation in connection with the Transaction made by, or procured by a third party for, Buyer and/or each Investor (or their respective affiliates) promptly upon request. The obligations under this
Section 1.4 shall be valid and binding as against an Investor whether or not the Transaction is consummated, and shall survive the termination of the other terms of this Agreement subject to the last two sentences of Section 1.4.1,
provided in each case that such fees, expenses or liabilities are not paid directly by Buyer. 
 1.5 Notice of Closing; Receipt of
Notices Pursuant to Purchase Agreement. Buyer will use its reasonable best efforts to provide each Investor with at least fifteen (15) days prior notice of the Closing Date under the Purchase Agreement; provided that the failure to
provide such notice will not relieve an Investor of its obligations under this Agreement. Any notices or correspondence received by Buyer under, in connection with, or related to the Purchase Agreement shall be promptly provided to each Investor at
the address set forth in the Equity Commitment Letters (in the case of notice to be provided to GE pursuant to this sentence, notice to ASC at the address set forth in its Equity Commitment Letter shall be sufficient), or any other address
designated by such Investor in writing to Buyer. 
 1.6 Representations, Warranties and Covenants. 

1.6.1 Each Investor hereby represents and warrants to the other Investor that such Investor has (i) the full power and authority to carry
on its businesses as now conducted and to enter into and perform its obligations under this Agreement and (ii) authorized the execution, delivery and performance of this Agreement and such other documents, instruments and agreements to which it
is a party in connection with the transactions contemplated by this Agreement. 

  
 4 

 1.6.2 Each Investor hereby represents, warrants and covenants to the other Investor that the
information supplied in writing by such Investor, if any, in connection with filings or notifications under, or relating to, the Antitrust Laws is and will be accurate and complete in all material respects. 

1.6.3 Each Investor hereby represents and warrants to the other Investor that it has not entered into any agreement, arrangement or
understanding with Seller with respect to the subject matter of this Agreement and the Purchase Agreement, other than the agreements expressly contemplated by this Agreement and the Purchase Agreement and that it has provided (or made available)
true and complete copies of such agreements (and any amendments, supplements or other material communications relating thereto) to the other Investor. 

1.7 Antitrust; Other Matters. Each Investor shall use its reasonable best efforts to supply and provide information that is accurate in
all material respects to any Governmental Authority requesting such information in connection with any filing or notifications under, or relating to, applicable Laws. If any Governmental Authority asserts any objections under the HSR Act or any
other applicable Laws with respect to the Transaction and such objections relate to the activities or investments of an Investor or such Investor’s Affiliates prior to the Closing Date (the “Affected Investor”), such
Affected Investor will use its reasonable best efforts (at its sole expense, including paying any Investor Expenses in respect thereof, and not subject to any reimbursement under Section 1.4) to enable Buyer to resolve such objections,
including using such Affected Investor’s reasonable best efforts to vigorously contest and resist any action, suit or proceeding that prohibits, prevents or restricts the consummation of the Transaction. Notwithstanding the foregoing, in no
event shall any Affected Investor be required to agree to or comply with any order, restriction, prohibition or limitation in connection with regulatory and competition matters. 

1.8 Deposit Letter of Credit. In the event the Investors decide unanimously that their obligations to fund, or cause its affiliate
party thereto to fund, their respective Commitments under the Equity Commitment Letters have not been met and therefore to not fund their respective Commitments, the Investors shall cooperate in defending any claim that the Seller is entitled to
draw upon the Deposit Letter of Credit. 
 1.9 Publicity. Each party hereto will coordinate in good faith any and all press releases
and other public relations matters with respect to the Transaction and the transactions contemplated hereby. Unless otherwise required by law or the rules of any stock exchange or regulatory authority, no party hereto may issue any press release or
otherwise make any public announcement or comment on the Transaction and the transactions contemplated hereby without the unanimous consent of the Investors; provided, however, that nothing contained herein shall prohibit the Investors
from communicating directly with their respective limited partners or investors; and, provided, further, that nothing contained in this Section 1.9 shall restrict Arc from discussing Buyer and its subsidiaries (including the Company) and their
respective businesses (including assets, liabilities, prospects and condition, financial or otherwise, of any thereof) from and after the Closing, including on earnings calls, in earnings releases, and otherwise. 

1.10 Side Agreements. Buyer will not enter into any agreement with an Investor that has the effect of discriminating against the other
Investor in a manner that is adverse to such 

  
 5 

 
other Investor without such other Investor’s consent, except to the extent explicitly permitted or required by the terms of this Agreement. No Investor shall enter into any agreement with
Buyer that has the effect of discriminating against the other Investor without such Investor’s consent. Buyer shall provide the Investors with a copy of any agreement to be entered into with any Investor prior to the execution of such
agreement. 
  

	2.	MISCELLANEOUS.

the date hereof and shall terminate upon the earliest of (i) the Closing pursuant to the Purchase Agreement, and (ii) the termination of the Purchase Agreement; provided, however, that any liability for failure to comply with
the terms of this Agreement shall survive any such termination. Notwithstanding the foregoing, Article 2, Section 1.3.1, Section 1.3.2, Section 1.3.3 and Sections 1.4, 1.5, 1.6 and 1.8 of this Agreement shall survive indefinitely
(subject to applicable statute of limitations) following the termination of this Agreement.

 EXECUTION VERSION 

ARC LOGISTICS PARTNERS LP 

February 19, 2015 
 Arc Terminals Joliet Holdings
LLC 
 c/o Arc Logistics Partners LP 
 725 Fifth Avenue, 19th
Floor 
 New York, NY 10022 
 Ladies and Gentlemen: 

This letter agreement sets forth the commitment of Arc Logistics Partners LP (“Sponsor”), on the terms and
subject to the conditions described below, to purchase, or cause the purchase of, the equity of Arc Terminals Joliet Holdings LLC, a Delaware limited liability company (“Buyer”) in connection with the transaction contemplated
by that certain Membership Interest Purchase Agreement dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Purchase Agreement”) and entered into concurrently herewith
by and among Buyer and CenterPoint Properties Trust (“Seller”), pursuant to which Buyer has agreed, subject to and in accordance with the terms and conditions thereof, to purchase from Seller all of Seller’s right, title
and interest in all of the issued and outstanding limited liability company interests of Joliet Bulk, Barge & Rail LLC, a Delaware limited liability company (the “Company”; and such acquisition, the
“Transaction”). Each capitalized term used but not defined in this letter agreement will have the meaning ascribed to it in the Purchase Agreement, except as otherwise provided below. 

1. Commitment. In connection with the execution of the Purchase Agreement, Buyer has received separate equity commitment
letters, each dated the date hereof (each, a “Co-Sponsor Equity Commitment Letter”), from each of the persons listed on Schedule A, other than the undersigned Sponsor (such persons, collectively, the
“Co-Sponsors”), wherein each Co-Sponsor has agreed that at Closing, subject to the terms and conditions set forth in its respective Co-Sponsor Equity Commitment Letter, it will contribute or cause to be contributed to Buyer
the amount of equity set forth therein (collectively, the “Co-Sponsor Equity Commitment”), which amount shall be used by Buyer to consummate the Transaction. Sponsor hereby agrees, on the terms and subject to the conditions
set forth in this letter agreement, to purchase (or cause the purchase of) at the Closing equity securities of Buyer (the “Buyer Securities”) for an aggregate cash purchase price (in cash in immediately available funds) of
not less than the amount set forth next to the Sponsor’s name on Schedule A (the “Commitment”), for the purpose of providing a portion of the cash required to fund a portion of, and together with the Co-Sponsor Equity
Commitments, providing all of the cash required to fund, the Purchase Price and to pay the related expenses of Buyer. Notwithstanding anything to the contrary contained herein, in no event shall the aggregate liability of Sponsor hereunder exceed
the amount of the Commitment. Sponsor may effect the purchase of the Buyer Securities directly or indirectly through one or more affiliated entities or other co-investors designated by it 

 
and may structure the funding of such amounts into Buyer through one or more intermediate entities; however, no such action will reduce the amount of the Commitment or otherwise affect the
obligations of Sponsor under this letter agreement. In the event Buyer does not require all of the equity with respect to which Sponsor has made this Commitment in order to consummate the Transaction, the amount to be funded under this letter
agreement may be reduced as determined by Sponsor; provided that such reduction does not and will not, directly or indirectly, cause or result in the failure of any condition to the Debt Financing, and no such reduction shall (i) relieve the
Sponsor of its obligations under this letter agreement or any Co-Sponsor under such Co-Sponsor’s Co-Sponsor Equity Commitment Letter or (ii) prevent or materially impair or delay the consummation of the Transaction. 

2. Conditions. The obligation of Sponsor to fund or cause the funding of the Commitment shall be subject only to (i) the
satisfaction, or, to the extent legally permissible, waiver by Buyer, of each of the conditions to Buyer’s obligations to consummate the Transaction set forth in Section 8.1 of the Purchase Agreement (other than those conditions that, by
their nature, are to be satisfied at the Closing, but subject to their satisfaction at the Closing, or those conditions that are not satisfied in accordance with the terms of the Purchase Agreement), (ii) the Debt Financing (including any
Substitute Financing) has been funded in accordance with the terms thereof or will be funded on the date Closing is required to occur pursuant to the Purchase Agreement if the Equity Financing is funded at such date and (iii) the concurrent
consummation of the Closing in accordance with the terms of the Purchase Agreement.  
 3. Enforceability. Subject to
the immediately following sentence, this letter agreement may only be enforced by Buyer, and nothing set forth in this letter shall be construed to confer upon or give to Seller or any other Person (including Buyer’s and Seller’s direct
and indirect creditors other than, for the avoidance of doubt, Seller as a creditor of Buyer), other than the parties hereto and their respective successors and permitted assigns, any benefits, rights or remedies under or by reason of this letter
agreement, or any rights to enforce the Commitment or to cause Buyer to enforce the Commitment. Subject to all terms and conditions of the Purchase Agreement, including Section 11.3 of the Purchase Agreement, Seller is hereby made a third party
beneficiary of the rights granted hereby only for the purpose of seeking specific performance of Buyer’s right to cause the Commitment to be funded (solely to the extent that Buyer can enforce the Commitment in accordance with the terms
hereof). Any exercise of such third party beneficiary rights are subject to Seller’s prior delivery of written notice to Buyer and Sponsor stating Seller’s unqualified acceptance of, and agreement to comply with, the provisions and
limitations of this letter agreement. The exercise by Buyer or Seller of any right to enforce this letter agreement does not give rise to any other remedies, monetary or otherwise. This letter agreement is being entered into by Buyer and Sponsor to
induce the Seller to enter into the Purchase Agreement. The Sponsor hereby waives any defense to specific performance that a remedy at law would be adequate or that, absent specific performance, no irreparable harm would be suffered and any
requirement under applicable law to post a bond or other security as a prerequisite to obtaining equitable relief. 
 4. No
Modification; Entire Agreement. This letter agreement may not be amended or otherwise modified without the prior written consent of Buyer, Sponsor and Seller. A written release or waiver by a party hereto of any rights hereunder shall be
deemed an amendment or modification hereof. This letter agreement constitutes the sole agreement, and 

  
 2 

 
supersedes all prior agreements, understandings and statements, written or oral, between Sponsor or any of its Affiliates, on the one hand, and Buyer or any of its Affiliates, on the other, with
respect to the transactions contemplated hereby. 
 5. Governing Law; Submission to Jurisdiction; Waiver of Jury Trial 

(a) This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York without giving effect to
any choice or conflict of law provision or rule (whether of such state or any other jurisdiction) that would cause the application of the Law of any jurisdiction other than those of the State of New York. 

(b) EACH OF THE PARTIES IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF NEW YORK STATE OR THE UNITED STATES FEDERAL COURTS
SITTING IN NEW YORK COUNTY, STATE OF NEW YORK FOR THE PURPOSES OF ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF OR RELATING TO THIS LETTER AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY. EACH OF THE PARTIES IRREVOCABLY AND UNCONDITIONALLY
WAIVES ANY OBJECTION TO THE LAYING OF VENUE OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS LETTER AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN THE COURTS OF NEW YORK STATE OR THE UNITED STATES FEDERAL COURTS SITTING IN
NEW YORK COUNTY, STATE OF NEW YORK AND WAIVES ANY CLAIM THAT SUCH SUIT OR PROCEEDING HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. EACH PARTY AGREES THAT LIABILITY ARISING OUT OF OR RELATING TO THIS LETTER AGREEMENT OR ANY TRANSACTION CONTEMPLATED
HEREBY SHALL BE DETERMINED SOLELY BY A FINAL AND UNAPPEALABLE JUDGMENT IN ANY ACTION OR PROCEEDING (OR A SETTLEMENT TANTAMOUNT THERETO), AND ANY SUCH FINAL AND UNAPPEALABLE JUDGMENT SHALL BE CONCLUSIVE AND MAY BE ENFORCED BY SUIT ON THE JUDGMENT IN
ANY JURISDICTION WITHIN OR OUTSIDE THE UNITED STATES OR IN ANY OTHER MANNER PROVIDED IN LAW OR IN EQUITY.

February 19, 2015 
 Arc Terminals Joliet Holdings
LLC 
 c/o Arc Logistics Partners LP 
 725 Fifth Avenue, 19th
Floor 
 New York, NY 10022 
 Ladies and Gentlemen: 

This letter agreement sets forth the commitment of Aircraft Services Corporation (“Sponsor”), on the terms and subject
to the conditions described below, to purchase, or cause the purchase of, the equity of Arc Terminals Joliet Holdings LLC, a Delaware limited liability company (“Buyer”) in connection with the transaction contemplated by that
certain Membership Interest Purchase Agreement dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Purchase Agreement”) and entered into concurrently herewith by and
among Buyer and CenterPoint Properties Trust (“Seller”), pursuant to which Buyer has agreed, subject to and in accordance with the terms and conditions thereof, to purchase from Seller all of Seller’s right, title and
interest in all of the issued and outstanding limited liability company interests of Joliet Bulk, Barge & Rail LLC, a Delaware limited liability company (the “Company”; and such acquisition, the
“Transaction”). Each capitalized term used but not defined in this letter agreement will have the meaning ascribed to it in the Purchase Agreement, except as otherwise provided below. 

1. Commitment. In connection with the execution of the Purchase Agreement, Buyer has received separate equity commitment
letters, each dated the date hereof (each, a “Co-Sponsor Equity Commitment Letter”), from each of the persons listed on Schedule A, other than the undersigned Sponsor (such persons, collectively, the
“Co-Sponsors”), wherein each Co-Sponsor has agreed that at Closing, subject to the terms and conditions set forth in its respective Co-Sponsor Equity Commitment Letter, it will contribute or cause to be contributed to Buyer
the amount of equity set forth therein (collectively, the “Co-Sponsor Equity Commitment”), which amount shall be used by Buyer to consummate the Transaction. Sponsor hereby agrees, on the terms and subject to the conditions
set forth in this letter agreement, to purchase (or cause the purchase of) at the Closing equity securities of Buyer (the “Buyer Securities”) for an aggregate cash purchase price (in cash in immediately available funds) of
not less than the amount set forth next to the Sponsor’s name on Schedule A (the “Commitment”), for the purpose of providing a portion of the cash required to fund a portion of, and together with the Co-Sponsor Equity
Commitments, providing all of the cash required to fund, the Purchase Price and to pay the related expenses of Buyer. Notwithstanding anything to the contrary contained herein, in no event shall the aggregate liability of Sponsor hereunder exceed
the amount of the Commitment. Sponsor may effect the purchase of the Buyer Securities directly or indirectly through one or more affiliated entities or other co-investors designated by it 

 
and may structure the funding of such amounts into Buyer through one or more intermediate entities; however, no such action will reduce the amount of the Commitment or otherwise affect the
obligations of Sponsor under this letter agreement. In the event Buyer does not require all of the equity with respect to which Sponsor has made this Commitment in order to consummate the Transaction, the amount to be funded under this letter
agreement may be reduced as determined by Sponsor; provided that such reduction does not and will not, directly or indirectly, cause or result in the failure of any condition to the Debt Financing, and no such reduction shall (i) relieve the
Sponsor of its obligations under this letter agreement or any Co-Sponsor under such Co-Sponsor’s Co-Sponsor Equity Commitment Letter or (ii) prevent or materially impair or delay the consummation of the Transaction. 

2. Conditions. The obligation of Sponsor to fund or cause the funding of the Commitment shall be subject only to (i) the
satisfaction, or, to the extent legally permissible, waiver by Buyer, of each of the conditions to Buyer’s obligations to consummate the Transaction set forth in Section 8.1 of the Purchase Agreement (other than those conditions that, by
their nature, are to be satisfied at the Closing, but subject to their satisfaction at the Closing, or those conditions that are not satisfied in accordance with the terms of the Purchase Agreement), (ii) the Debt Financing (including any
Substitute Financing) has been funded in accordance with the terms thereof or will be funded on the date Closing is required to occur pursuant to the Purchase Agreement if the Equity Financing is funded at such date and (iii) the concurrent
consummation of the Closing in accordance with the terms of the Purchase Agreement. 
 3. Enforceability. Subject to the
immediately following sentence, this letter agreement may only be enforced by Buyer, and nothing set forth in this letter shall be construed to confer upon or give to Seller or any other Person (including Buyer’s and Seller’s direct and
indirect creditors other than, for the avoidance of doubt, Seller as a creditor of Buyer), other than the parties hereto and their respective successors and permitted assigns, any benefits, rights or remedies under or by reason of this letter
agreement, or any rights to enforce the Commitment or to cause Buyer to enforce the Commitment. Subject to all terms and conditions of the Purchase Agreement, including Section 11.3 of the Purchase Agreement, Seller is hereby made a third party
beneficiary of the rights granted hereby only for the purpose of seeking specific performance of Buyer’s right to cause the Commitment to be funded (solely to the extent that Buyer can enforce the Commitment in accordance with the terms
hereof). Any exercise of such third party beneficiary rights are subject to Seller’s prior delivery of written notice to Buyer and Sponsor stating Seller’s unqualified acceptance of, and agreement to comply with, the provisions and
limitations of this letter agreement. The exercise by Buyer or Seller of any right to enforce this letter agreement does not give rise to any other remedies, monetary or otherwise. This letter agreement is being entered into by Buyer and Sponsor to
induce the Seller to enter into the Purchase Agreement. The Sponsor hereby waives any defense to specific performance that a remedy at law would be adequate or that, absent specific performance, no irreparable harm would be suffered and any
requirement under applicable law to post a bond or other security as a prerequisite to obtaining equitable relief. 
 4. No
Modification; Entire Agreement. This letter agreement may not be amended or otherwise modified without the prior written consent of Buyer, Sponsor and Seller. A written release or waiver by a party hereto of any rights hereunder shall be
deemed an amendment or modification hereof. This letter agreement constitutes the sole agreement, and 

  
 2 

 
supersedes all prior agreements, understandings and statements, written or oral, between Sponsor or any of its Affiliates, on the one hand, and Buyer or any of its Affiliates, on the other, with
respect to the transactions contemplated hereby. 
 5. Governing Law; Submission to Jurisdiction; Waiver of Jury Trial 

(a) This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York without giving effect to
any choice or conflict of law provision or rule (whether of such state or any other jurisdiction) that would cause the application of the Law of any jurisdiction other than those of the State of New York. 

(b) EACH OF THE PARTIES IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF NEW YORK STATE OR THE UNITED STATES FEDERAL COURTS
SITTING IN NEW YORK COUNTY, STATE OF NEW YORK FOR THE PURPOSES OF ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF OR RELATING TO THIS LETTER AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY. EACH OF THE PARTIES IRREVOCABLY AND UNCONDITIONALLY
WAIVES ANY OBJECTION TO THE LAYING OF VENUE OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS LETTER AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN THE COURTS OF NEW YORK STATE OR THE UNITED STATES FEDERAL COURTS SITTING IN
NEW YORK COUNTY, STATE OF NEW YORK AND WAIVES ANY CLAIM THAT SUCH SUIT OR PROCEEDING HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. EACH PARTY AGREES THAT LIABILITY ARISING OUT OF OR RELATING TO THIS LETTER AGREEMENT OR ANY TRANSACTION CONTEMPLATED
HEREBY SHALL BE DETERMINED SOLELY BY A FINAL AND UNAPPEALABLE JUDGMENT IN ANY ACTION OR PROCEEDING (OR A SETTLEMENT TANTAMOUNT THERETO), AND ANY SUCH FINAL AND UNAPPEALABLE JUDGMENT SHALL BE CONCLUSIVE AND MAY BE ENFORCED BY SUIT ON THE JUDGMENT IN
ANY JURISDICTION WITHIN OR OUTSIDE THE UNITED STATES OR IN ANY OTHER MANNER PROVIDED IN LAW OR IN EQUITY. 
 (c) EACH PARTY ACKNOWLEDGES AND
AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS LETTER AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT
OF ANY LEGAL ACTION ARISING DIRECTLY OR INDIRECTLY OUT OF OR RELATING TO THIS LETTER AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY TO THIS LETTER AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY MAKES THIS WAIVER
VOLUNTARILY, AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS LETTER AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 5.

applicable rules of any national securities exchange (including, without limitation, a summary description thereof in the documents filed or furnished by Seller with the U.S. Securities and Exchange Commission) or (iii) in connection with any

Acquisition Credit Facility 

Commitment Letter 
 Ladies and Gentlemen: 

Arc Terminals Holdings LLC (the “Company” or “you”) has advised SunTrust Bank and SunTrust
Robinson Humphrey, Inc. (the “Lead Arranger” and, together with SunTrust Bank, “SunTrust” or “we”) that the Company is seeking certain amendments (collectively, the
“Amendment”) to that certain Second Amended and Restated Revolving Credit Agreement, dated as of November 12, 2013 (as amended to date, the “Existing Credit Agreement”), by and among the Company,
the lenders from time to time party thereto (collectively, the “Existing Lenders”) and SunTrust Bank, as administrative agent for the Existing Lenders (in such capacity, the “Administrative Agent”),
which Amendment shall, among other things, (a) permit the acquisition (the “Acquisition”) by the Company, either directly or indirectly, of sixty percent (60%) of the membership interests of Joliet Bulk,
Barge & Rail LLC (the “Acquired Business”) pursuant to that certain Membership Interest Purchase Agreement, dated as of February 19, 2015 (as amended, supplemented or otherwise modified, the “Purchase
Agreement”), between Arc Terminals Joliet Holdings LLC, a subsidiary of the Company (the “Buyer”), and CenterPoint Properties Trust (the “Seller”) and (b) provide incremental
financing to fund a portion of the Acquisition. 
 This letter agreement and the Summary of Principal Terms and Conditions attached hereto
as Annex I (the “Incremental Term Sheet”) describes the general terms and conditions for an incremental senior secured credit facility, which will be comprised of an increase to the revolving credit facility set forth
in the Existing Credit Agreement (such increase, the “Incremental Facility”) in up to an amount such that the aggregate amount of all outstanding loans and commitments under the Existing Credit Agreement (as amended by the
Amendment) will not exceed $275,000,000. In addition, you have requested that SunTrust Bank provide an underwritten commitment for a backstop senior secured credit facility of up to $275,000,000 (the “Backstop Facility” and,
together with the Incremental Facility (or either individually, as the context shall require), the “Acquisition Credit Facility”) to be provided to the Company in order to refinance the Existing Credit Agreement in the event
that the Company is unable to obtain the consents of the requisite Existing Lenders for the Amendment, as more fully described in the Summary of Principal Terms and Conditions attached hereto as Annex II (the “Backstop Term
Sheet” and, together with the Incremental Term Sheet, the “Term Sheet”). The Company further intends to raise an amount to be determined in common equity (the “Arc Equity Contribution”),
which will be directly or indirectly contributed to the Buyer. In addition, an affiliate of General Electric Capital Corporation (“GE Capital”) intends to contribute an amount to be determined to the Buyer (the “GE
Equity Contribution”)

in connection with the consummation of the Acquisition. All transactions described above, together with the financing contemplated hereby, shall be referred to herein as the
“Transactions”. Capitalized terms used in this letter but not defined herein shall have the meanings given to them in the Incremental Term Sheet or the Backstop Term Sheet, as applicable. 

 

	A.	Commitment 

 SunTrust Bank is pleased to commit to provide 100% of the principal
amount of each of the Acquisition Credit Facilities described and defined in the Term Sheet, subject to the terms and conditions set forth in this letter and the Term Sheet (collectively, this “Commitment Letter”). 

 

	B.	Syndication 

 The Lead Arranger reserves the right, before or after the execution
of the definitive documentation for the Acquisition Credit Facility (collectively, the “Financing Documentation”), to syndicate all or a portion of SunTrust Bank’s commitments to one or more other financial institutions
reasonably acceptable to the Company that will become parties to the Financing Documentation (such financial institutions, together with the Existing Lenders, the “Lenders”); provided that, notwithstanding SunTrust
Bank’s right to syndicate the Acquisition Credit Facility and receive commitments with respect thereto, (x) SunTrust shall not be relieved, released or novated from its obligations hereunder (including its obligation to fund the
Acquisition Credit Facility on the Closing Date) in connection with any syndication, assignment or participation of the Acquisition Credit Facility, including its commitments in respect thereof, until after the Closing Date has occurred, (y) no
assignment or novation shall become effective with respect to all or any portion of SunTrust Bank’s commitments in respect of the Acquisition Credit Facility until the initial funding thereof and (z) unless SunTrust and the Company
otherwise agree in writing, SunTrust Bank shall retain exclusive control over all rights and obligations with respect to its commitments in respect of the Acquisition Credit Facility, including all rights with respect to consents, modifications,
supplements, waivers and amendments, until a Successful Syndication (as defined in the Fee Letter (as defined below)) has occurred. The Company understands that the Lead Arranger intends to commence such syndication efforts promptly and the Lead
Arranger may elect to appoint one or more agents to assist it in such syndication efforts. 
 You hereby appoint SunTrust Robinson Humphrey,
Inc. to act, and the Lead Arranger agrees to act, as lead arranger and book manager for the Acquisition Credit Facility, subject to the terms and conditions of this Commitment Letter. The Lead Arranger will manage all aspects of the syndication of
the Acquisition Credit Facility in consultation with the Company, including the timing of all offers to potential Lenders, the determination of all amounts offered to potential Lenders, the selection of Lenders (subject to the approval of the
Company, such approval not to be unreasonably withheld), the allocation of commitments among the Lenders, and the determination of compensation and titles (such as co-agent, managing agent, etc.), if any, to be given such Lenders. It is agreed that
no other agents, co-agents or arrangers will be appointed, or other titles conferred, except as mutually agreed to by the Company and by the Lead Arranger, and that no Lender will receive any compensation for its commitment to, or participation in,
the Acquisition Credit Facility or the Amendment except as expressly set forth in the Term Sheet or the Fee Letter or as otherwise mutually agreed to by the Company and by the Lead Arranger. 

Without limiting the Company’s obligations to assist with the marketing and syndication efforts as set forth herein, it is understood
that SunTrust Bank’s commitments hereunder are not conditioned upon the syndication of, or receipt of commitments from other Lenders in respect of, the Acquisition Credit Facility and in no event shall the commencement or successful completion
of syndication of the Acquisition Credit Facility constitute a condition to the availability of the Acquisition Credit Facility on the Closing Date. 

 Arc Terminals Holdings LLC

 Until the later of (i) the Closing Date and (ii) the earlier of (A) the date
upon which a Successful Syndication is achieved and (B) 90 days after the Closing Date, the Company agrees to actively assist the Lead Arranger in attempting to complete a timely syndication of the Acquisition Credit Facility and shall take all
action as the Lead Arranger may reasonably request related thereto. The Company’s assistance shall include (i) making available senior management, representatives and advisors of the Company, Arc Logistics Partners LLP (the
“MLP”), Arc Logistics GP LLC (together with the MLP, the “MLP Affiliates”) and their respective subsidiaries (and shall request the Seller to make available its senior management, representatives and
advisors involved in the Transactions or otherwise substantively involved in the development of the Acquired Business) to participate in meetings with potential Lenders and to provide information to potential Lenders at such times and places as are
mutually agreed upon; (ii) ensuring that the syndication effort benefits from the existing lending relationships of the Company, the MLP Affiliates and their respective subsidiaries, and using commercially reasonable efforts to ensure that the
syndication effort benefits from the existing lending relationships, if any, of the Acquired Business; (iii) assisting in the preparation of customary marketing materials (which may include an information memorandum, if requested by the Lead
Arranger) to be used in connection with the syndication, in form and substance reasonably acceptable to the Lead Arranger and the Company, at least 20 days prior to the closing of the Acquisition Credit Facility; (iv) preparing and providing to
the Lead Arranger (and requesting the Seller, with respect to the Acquired Business, to prepare and provide to the Lead Arranger) all information with respect to the Company, the Acquired Business, their respective subsidiaries and the Transactions,
including, without limitation, all financial information and projections (the “Projections”), reasonably requested by the Lead Arranger that is usual and customary in financings of this type; and (v) furnishing to us an
electronic version of the Company’s trademarks, service marks and corporate logo for use in marketing materials for the purpose of facilitating the syndication of the Acquisition Credit Facility; provided that such license shall be used
solely for the purpose described above, is granted without any fee and may not be assigned or transferred. 
 For the avoidance of doubt,
the Company will not be required to provide any information to the extent that the provision thereof would violate any law, rule or regulation, or any obligation of confidentiality binding upon the Company, the Acquired Business or any of their
respective affiliates. Notwithstanding anything herein to the contrary, the only financial statements that shall be required to be provided to SunTrust with respect to the Acquired Business in connection with the syndication of the Acquisition
Credit Facility shall be such financial statements, if any, made available to the Company pursuant to the Purchase Agreement. 
 To ensure
an orderly and effective syndication of the Acquisition Credit Facility, the Company agrees that, until the earlier of (A) the date upon which a Successful Syndication is achieved and (B) 90 days after the Closing Date, the Company and the
Guarantors (as defined in the Existing Credit Agreement) shall not, and shall not permit their respective subsidiaries to, arrange, sell, syndicate or issue any credit facilities or debt security (including any renewals thereof) except with the
prior written consent of the Lead Arranger (excluding any indebtedness outstanding under the Existing Credit Agreement and excluding the ongoing ordinary course short-term working capital facilities and ongoing ordinary course capital lease,
purchase money and equipment financings of the Company and its subsidiaries and any other indebtedness permitted to be borrowed under the Existing Credit Agreement (other than the Qualified Senior Notes (as defined therein))).

	C.	Conditions Precedent 

 The undertakings and obligations of SunTrust under this
Commitment Letter and the commitment hereunder to fund the Acquisition Credit Facility on the Closing Date are subject only to (i) the accuracy in all material respects of all Specified Acquisition Representations and Specified Representations;
(ii) a closing of the Acquisition Credit Facility on or prior to May 18, 2015 unless mutually extended by the Company and SunTrust; and (iii) the satisfaction of the other conditions precedent set forth (x) in the case of the
Incremental Facility, in the Incremental Term Sheet under the section “Conditions to Closing” and (y) in the case of the Backstop Facility, in the Backstop Term Sheet under the section “Conditions to Closing”; and upon
satisfaction (or waiver by SunTrust) of such conditions, the initial funding of the Acquisition Credit Facility shall occur. It is understood and agreed that there are no other conditions (implied or otherwise) to the commitment hereunder to fund
the Acquisition Credit Facility, including compliance with any other terms of this Commitment Letter, the Fee Letter or the Financing Documentation. 

Notwithstanding anything in this Commitment Letter, the Fee Letter, the Financing Documentation or any other letter agreement or other
undertaking concerning the financing of the Acquisition to the contrary, (i) the only representations with respect to the Company, the Acquired Business and their respective subsidiaries and their respective businesses and assets, the accuracy
of which shall be a condition to the availability of the Acquisition Credit Facility on the Closing Date, shall be (A) such of the representations with respect to the Acquired Business in the Purchase Agreement as are material to the interests
of the Lenders, but only to the extent that the Buyer has the right to terminate its obligations under the Purchase Agreement as a result of a breach of one or more of such representations in the Purchase Agreement (the “Specified
Acquisition Representations”) and (B) the Specified Representations (as defined below) in the Financing Documentation and (ii) the terms of the Financing Documentation shall be in a form such that they do not impair the
availability of the Acquisition Credit Facility on the Closing Date if the applicable conditions set forth in the section entitled “Conditions to Closing” in the applicable Term Sheet are satisfied (the “Certain Funds
Provisions”). For purposes hereof, “Specified Representations” means the representations and warranties of the Company and its affiliates set forth in the Financing Documentation (which such representations and
warranties will be substantially the same as those set forth in the Existing Credit Agreement, subject to the Documentation Principles) relating to legal existence; power and authority, due authorization, execution and delivery, validity and
enforceability, in each case, related to the entering into and performance of the Financing Documentation; no conflicts of the Financing Documentation with respect to organizational documents; solvency on the Closing Date of the Company and its
subsidiaries; Federal Reserve margin regulations; the Investment Company Act; the PATRIOT Act; and creation, validity and perfection of security interests in the equity interests of the Buyer owned, directly or indirectly, by the Company. 

 

	D.	Information Requirements 

 You represent and warrant to SunTrust that (i) all
written information, other than in connection with the Projections and other than information of a general economic or industry specific nature, that has been or will be made available to SunTrust or any of the Lenders by the Company and its
subsidiaries or any of their respective representatives (or on your or their behalf) in connection with the Acquisition Credit Facility or the Financing Documentation (such written information, collectively, the
“Information”), when taken as a whole, is or will be when furnished correct in all material respects and does not or will not, when furnished and when taken as a whole (and when taken as a whole with all information in
respect of the MLP as filed with the Securities Exchange Commission under any current or 

 Arc Terminals Holdings LLC 

February 19, 2015 
 Page 5 

 

 
periodic report), contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not materially misleading in light
of the circumstances under which such statements are made (giving effect to all supplements and updates thereto prior to the Closing Date and, in the case of Information supplemented or updated after the Closing Date, prior to when a Successful
Syndication is achieved); and (ii) the Projections have been or will be prepared in good faith based upon assumptions believed by you to be reasonable at the time furnished; it being understood that the Projections are as to future events and
are not to be viewed as facts, the Projections are subject to significant uncertainties and contingencies, many of which are beyond your control, that no assurance can be given that any particular Projections will be realized and that actual results
during the period covered by any such Projections may differ from the projected results and such differences may be material. You agree that if, at any time prior to the later of (i) the Closing Date and (ii) the earlier of (A) the
date a Successful Syndication is achieved and (B) 90 days after the Closing Date, you become aware that any of the representations and warranties in the preceding sentence would be incorrect if the Information and the Projections were being
furnished, and such representations were being made, at such time, then you will use commercially reasonable efforts to supplement the Information and the Projections so that (with respect to the Information relating to the Acquired Business and its
subsidiaries, to the best of your knowledge) the representation and warranty contained in this paragraph remains correct in all material respects. In issuing the commitments and undertakings hereunder and in arranging and syndicating the Acquisition
Credit Facility, SunTrust Bank and the Lead Arranger are relying on the accuracy of the Information and the Projections without independent verification thereof. 
  

	E.	Fees and Expenses; Indemnification  

 1. Fees and Expenses. In addition to
the fees described in the Term Sheet, you will pay at the times specified therein the fees set forth in that certain letter agreement dated as of the date hereof, executed by SunTrust Bank and the Lead Arranger and acknowledged and agreed to by the
Company relating to this Commitment Letter (the “Fee Letter”). You also agree to pay or reimburse SunTrust on demand for any other fees mutually agreed to by the Company and SunTrust and all reasonable and documented
out-of-pocket costs and expenses incurred by SunTrust (whether incurred before or after the date hereof) in connection with the Acquisition Credit Facility, the preparation of the Financing Documentation and the syndication thereof, including,
without limitation, reasonable fees and disbursements of its counsel, regardless of whether the Acquisition Credit Facility closes. You will also pay all documented out-of-pocket costs and expenses of SunTrust (including, without limitation,
reasonable fees and disbursements of its counsel) incurred in connection with the enforcement of any of its rights and remedies hereunder, in each case on terms substantially the same as those set forth in the Existing Credit Agreement. 

2. Indemnification. You will indemnify and hold harmless the Lead Arranger, SunTrust Bank, their respective affiliates and their
respective directors, officers, employees, agents, representatives, legal counsel and consultants (each, an “Indemnified Person”) against, and to reimburse each Indemnified Person upon its demand for, any losses, claims,
damages, liabilities or other reasonable and documented out-of-pocket expenses (“Losses”) incurred by such Indemnified Person or asserted against such Indemnified Person by the Company, the Acquired Business, any of their
subsidiaries or affiliates or any other person or party arising out of or in connection with this Commitment Letter, the Fee Letter, the Financing Documentation, the Acquisition Credit Facility, the use of the proceeds thereof, the Acquisition or
any related transaction, or any claim, litigation, investigation or proceeding relating to any of the foregoing, and to reimburse each Indemnified Person upon demand for any reasonable and documented out-of-pocket legal or other expenses (limited to
one primary counsel for the Indemnified Persons collectively and, if necessary in the Indemnified Persons’ reasonable determination, one local counsel in each appropriate jurisdiction and one regulatory counsel and, solely, in the event of a
conflict of interest,

one additional primary counsel (and, if necessary, one additional local counsel in each appropriate jurisdiction and one additional regulatory counsel)) incurred in connection with investigating
or defending any of the foregoing; provided, however, that the foregoing indemnity will not, as to any Indemnified Person, apply to Losses to the extent resulting from (x) the gross negligence or willful misconduct of such
Indemnified Person, (y) a claim brought solely between or among Indemnified Persons (other than a claim against the Administrative Agent or the Lead Arranger acting pursuant to this Commitment Letter or in their capacity as such or any of their
respective affiliates or their respective directors, officers, employees, agents, representatives, legal counsel or consultants) not arising from any act or omission by you or any of your affiliates or (z) a claim brought by the Company or any
of its subsidiaries against an Indemnified Person for a material or bad faith breach of such Indemnified Person’s material obligations hereunder (in each case of the foregoing clauses (x), (y) and (z), as determined by a court of competent
jurisdiction in a final and non-appealable judgment). 
 The Company shall not, without the prior written consent of any Indemnified Person,
effect any settlement of any pending or threatened proceeding in respect of which such Indemnified Person is a party and indemnity has been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such
Indemnified Person from all liability on claims that are the subject matter of such indemnity. The Company shall not be liable for any settlement of any pending or threatened proceeding effected without the Company’s written consent (such
consent not to be unreasonably withheld or delayed). No Indemnified Person shall be responsible or liable for any damages arising from the use by others of the Information or other materials obtained through electronic telecommunications or other
information transmission systems (other than as a result of willful misconduct, bad faith or gross negligence of such Indemnified Person). Neither any Indemnified Person nor the Company shall be liable for any special, indirect, punitive, exemplary
or consequential damages that may be alleged as a result of this Commitment Letter, the Fee Letter, the Financing Documentation, the Acquisition Credit Facility, the use of proceeds thereof, the Acquisition or any related transaction. Neither any
Indemnified Person nor the Company shall be liable for any indirect or consequential damages in connection with its activities related to the Acquisition Credit Facility or the Financing Documentation.

brought in any such court and any claim that any such suit, action or proceeding has been brought in an inconvenient forum. A final judgment in any such suit, action or proceeding brought in any such court may be enforced in any other courts to
whose jurisdiction the Company or SunTrust are or may be subject, by suit upon judgment. Service of any process, summons, notice or document on the Company may be made by registered mail addressed to the Company at the address appearing at the

promptly thereof) or (iv) upon the request or demand of any regulatory authority having jurisdiction over the Company or any of its affiliates (in which case the Company, to the extent not prohibited by law, agrees to inform SunTrust promptly

			 •       
		If and to the extent GE has a regulatory issue, meaning any set of facts or circumstances in which the ownership by GE of the acquired interest gives rise to a material violation of applicable law that is not capable of
being cured within a reasonable period of time without undue harm or further liability to GE as a result of such violation, or gives rise to a reasonable belief by GE (based upon advice of counsel having requisite experience in such matters) that
such violation will arise, or gives rise to a requirement under applicable law, including banking regulations and applicable securities laws, that such acquired interests be transferred to a third party, then GE shall be permitted to transfer the
ownership interest to an unaffiliated transferee (other than a transferee that is a “material competitor” or “material customer” (in each case as defined in the LLC Agreement) of ARC or a subsidiary thereof, unless ARC shall have

			 •       
		GE will notify Arc of its intent to sell. Arc will have the right to provide a price within 30-days, after which GE will have 30 days to accept or reject; if GE rejects, GE will have 180-days to sell to a third-party at

		Buyer shall maintain capital accounts in compliance with Treas. Reg. § 1.704-1(b). Liquidating distributions shall be made (after paying off creditors) in accordance with the distribution waterfall (i.e., 40% and
60% for GE and Arc, respectively).
			
			 •       
		After giving effect to certain special allocations, net profits and net losses generally shall be allocated, for all tax purposes including the calculation of capital accounts of the members, in accordance with the
distribution waterfall (i.e. 40% and 60% for GE and ARC, respectively). Loss allocations shall be limited to the extent they would cause a member to have a capital account deficit. Certain special allocations may be required, inter alia, if a member
has a capital account deficit.

and each Purchaser hereby agrees, severally and not jointly, to purchase from the Partnership, its respective Purchased Units, and each Purchaser agrees, severally and not jointly, to pay the Partnership the Common Unit Price for each Purchased
Unit, in each case as set forth in Section 2.1(b). The respective obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the
performance of the obligations of any other Purchaser under this Agreement. Except as otherwise provided herein, the failure or waiver of performance under this Agreement by any Purchaser, or on its behalf, does not excuse performance by any other
Purchaser or by the Partnership with respect to the other Purchasers. Nothing contained herein and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or
any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Except as otherwise provided in this Agreement
or in the Registration Rights Agreement, each Purchaser shall be entitled to independently protect and enforce its rights, including the rights arising out of this Agreement or out of the Registration Rights Agreement, and it shall not be necessary
for any other Purchaser to be joined as an additional party in any proceeding for such purpose. It is expressly understood and agreed that each provision contained in this Agreement is between the Partnership and a Purchaser, solely, and not between
the Partnership and the Purchasers collectively and not between and among the Purchasers.

date for the distribution to the Partnership’s holders of Common Units with respect to the quarter ending March 31, 2015, the Common Unit Price shall be reduced by an amount equal to such per unit distribution and the number of Common

financial matters generally so as to be capable of evaluating the merits and risks of the prospective investment in the Purchased Units, is able to bear the economic risk of such investment and, at the present time, would be able to afford a
complete loss of such investment. 
 Section 4.9 Receipt of Information. Such Purchaser acknowledges that it has (a) had access
to the Partnership SEC Documents, (b) had access to information regarding the JBBR Acquisition and its potential effect on the Partnership’s operations and financial results and (c) been provided a reasonable opportunity to ask
questions of and receive answers from Representatives of the Partnership regarding such matters including matters with respect to the JBBR Acquisition. 

Section 4.10 Restricted Securities. Such Purchaser understands that the Purchased Units it is purchasing are characterized as
“restricted securities” under the federal securities Laws inasmuch as they are being acquired from the Partnership in a transaction not involving a public offering and that under such Laws and applicable regulations such securities may be
resold without registration under the Securities Act only in certain limited circumstances. In this connection, such Purchaser represents that it is knowledgeable with respect to Rule 144 of the Commission promulgated under the Securities Act. 

Section 4.11 Legend. Such Purchaser understands that the book-entry account maintained by the transfer agent evidencing ownership of
the Purchased Units will bear the legend or restrictive notation required by the Partnership Agreement as well as the following legend or restrictive notation: “These securities have not been registered under the Securities Act of 1933, as
amended (the “Securities Act”). These securities may not be sold, offered for sale, pledged or hypothecated in the absence of a registration statement in effect with respect to the securities under the Securities Act or pursuant to an
exemption from registration thereunder, in each case in accordance with all applicable securities laws of the states or other jurisdictions, and, in the case of a transaction exempt from registration, such securities may only be transferred if the
transfer agent for such securities has received documentation satisfactory to it that such transaction does not require registration under the Securities Act.” 

  
 17 

 Section 4.12 Short Selling. Such Purchaser represents that it has not entered into any
Short Sales of the Common Units owned by it since the time it first began discussions with the Partnership or the Placement Agent about the transactions contemplated by this Agreement; provided, however, subject to such Purchaser’s compliance
with its obligations under the U.S. federal securities laws and its internal policies, the above shall not apply, in the case of a Purchaser that is a large multi-unit investment or commercial banking organization, to activities in the normal course
of trading units of such Purchaser; provided, further, that subject to such Purchaser’s compliance with its obligations under the U.S. federal securities laws and its internal policies: (a) such Purchaser, for purposes hereof, shall not be
deemed to include any employees, subsidiaries or Affiliates that are effectively walled off by appropriate “Chinese Wall” information barriers approved by such Purchaser’s legal or compliance department (and thus have not been privy
to any information concerning this transaction) (a “Walled Off Person”) and (b) the foregoing representations in this paragraph shall not apply to any transaction by or on behalf of such Purchaser that was effected by a Walled
Off Person in the ordinary course of trading without the advice or participation of such Purchaser or receipt of confidential or other information regarding this transaction provided by such Purchaser to such entity. 

ARTICLE V  
 COVENANTS

 Section 5.1 Taking of Necessary Action. Each of the Parties hereto shall use its commercially reasonable efforts promptly to
take or cause to be taken all action and promptly to do or cause to be done all things necessary, proper or advisable under applicable Law and regulations to consummate and make effective the transactions between the Partnership and the Purchasers
contemplated by this Agreement related specifically to the acquisition of the Purchased Units; provided, that nothing contained herein shall require the Partnership to consummate the JBBR Acquisition. Without limiting the foregoing, the Partnership
and each Purchaser shall use its commercially reasonable efforts to make all filings and obtain all consents of Governmental Authorities that may be necessary or, in the reasonable opinion of the Purchasers or the Partnership, as the case may be,
advisable for the consummation of the transactions contemplated by this Agreement and the other Operative Documents. 
 Section 5.2
Disclosure; Interim Public Filings. The Partnership shall, as soon as practicable following execution of this Agreement, issue a press release disclosing all material terms of the transactions contemplated herein and in the other Operative
Documents. On or before the fourth Business Day following the date hereof, the Partnership shall file a Current Report on Form 8-K with the Commission (the “Form 8-K Filing”) describing the terms of the transactions contemplated by
the Operative Documents and the JBBR Purchase Agreement and including as exhibits to the Form 8-K the Operative Documents and the JBBR Purchase Agreement, in the form required by the Exchange Act. 

Section 5.3 Use of Proceeds. The Partnership shall use the collective proceeds from the sale of the Purchased Units to partially
finance the JBBR Acquisition. If the transactions contemplated by the JBBR Purchase Agreement are not closed concurrently with the Closing or within two Business Days thereafter or if any of the conditions set forth in Section 2.4 have not been
satisfied and a Purchaser paid its Commitment Amount in advance of the Closing, the 

  
 18 

 
Partnership shall return the Commitment Amount paid to the Partnership to the applicable Purchasers within two Business Days of receipt thereof and the transfer agent shall thereafter cancel the
Purchased Units. 
 Section 5.4 Certain Special Allocations of Book and Taxable Income. To the extent that the Common Unit Price
differs from the Per Unit Capital Amount as of the Closing Date for a then Outstanding Common Unit after taking into account the issuance of the Purchased Units, the General Partner intends to specially allocate Partnership items of book and taxable
income, gain, loss or deduction to the Purchasers so that the Per Unit Capital Amount with respect to their Purchased Units are equal to the Per Unit Capital Amounts with respect to other Common Units (and thus to assure fungibility of all Common
Units). Such special allocations will occur upon the earlier to occur of any taxable period of the Partnership ending upon, or after, (i) an event described in Section 5.5(d) of the Partnership Agreement or a sale of all or substantially
all of the assets of the Partnership occurring after the date of the issuance of the Purchased Units or (ii) the transfer of Purchased Units to a Person that is not an Affiliate of the Purchaser, in which case, such allocation shall be made
only with respect to the Purchased Units so transferred. A Purchaser holding a Purchased Unit shall be required to provide notice to the General Partner of the transfer of a Purchased Unit to a Person that is not an Affiliate of the Purchaser no
later than the last Business Day of the calendar year during which such transfer occurred, unless by virtue of the application of clause (i) above the General Partner has determined that the Purchased Units are consistent, on a per-unit basis,
with the capital accounts of the other holders of Common Units other than Purchased Units; provided, that such Purchaser may cure any failure to provide such notice by providing such notice within 20 days of the last Business Day of such calendar
year; provided, further, that the sole and exclusive remedy for any Purchaser’s failure to provide any such notice shall be the enforcement of the remedy of specific performance against such Purchaser and there will be no monetary damages. To
the maximum extent permissible under the Partnership Agreement or under applicable law, including under the Treasury Regulations issued under Section 704(b) of the Internal Revenue Code, the special allocations resulting from clause
(i) will be made through allocations of Unrealized Gain. 
 Section 5.5 Expenses. The Partnership shall pay up to $75,000 of
legal fees of Latham & Watkins LLP, counsel to the Purchasers, incurred in connection with the negotiation, execution, delivery and performance of this Agreement and the Registration Rights Agreement and the transactions contemplated hereby
and thereby, provided that any request for such payment is accompanied by a satisfactory written invoice for such expenses. If any action at law or equity is necessary to enforce or interpret the terms of any Operative Document, the prevailing Party
shall be entitled to reasonable attorney’s fees, costs and necessary disbursements in addition to any other relief to which such Party may be entitled. Any legal fees of Latham & Watkins LLP in excess of $75,000 shall be paid pro rata
by all the Purchasers in proportion to the aggregate number of Purchased Units purchased by each. 
 Section 5.6 Lock-Up Period.
Without the consent of those Purchasers entitled to, or who are the holders of, a majority of the Purchased Units, the Partnership shall not offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is
designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Partnership, or any affiliated company of the Partnership)
directly or indirectly, including through the filing (or 

  
 19 

 
participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position
within the meaning of Section 16 of the Exchange Act and the rules and regulations of the Commission promulgated thereunder with respect to, any Common Units or any securities convertible into, or exercisable, or exchangeable for, Common Units,
or publicly announce an intention to effect any such transaction, during the period commencing on the date of this Agreement and ending on the date that is 90 days after the Closing Date (the “Restricted Period”), provided, however,
that issuances of Common Units or any securities convertible into, or exercisable, or exchangeable for, Common Units pursuant to the Arc Logistics GP LLC Long-Term Incentive Plan or the Partnership’s Registration Statement required to be filed
with the Commission pursuant to the Registration Rights Agreement, are excluded from the foregoing; and provided, further, that nothing contained in this Section 5.6 shall prohibit the Partnership from issuing Common Units during the Restricted
Period provided that (i) such issuance occurs to fund (or to repay borrowings used to fund) an acquisition (including through the issuance of Common Units directly to a seller involved in such acquisition), (ii) the price per Common Unit
(before underwriting discounts and commissions and offering expenses) to the investor(s) or seller, as the case may be, is equal to or greater than $18.00 per Common Unit and (iii) the Board of Directors of the General Partner has determined in
good faith that the acquisition is expected to result in an increase, on a pro forma basis, in the amount of Distributable Cash Flow generated by the Partnership on a per-unit basis over the four succeeding quarter period (starting with the first
full quarter following the closing of such acquisition) taken as a whole as compared to the anticipated Distributable Cash Flow per unit excluding the effect of the acquisition; for purposes of this Section 5.6, “Distributable Cash
Flow” has the meaning assigned to that term in the Partnership’s Form 10-Q for the quarter ended September 30, 2014 as filed with the Commission. 

Section 5.7 Amendment of the Terminal Services Agreement and TSA Amendment. During the period commencing on the date hereof and ending
at the time of the Closing, the Partnership shall not, and shall not permit any of its Subsidiaries to, agree to the amendment or termination of (partially or completely), or consent to the waiver or relinquishment of any right under, the Terminal
Services Agreement (as defined in the JBBR Purchase Agreement) or the TSA Amendment (as defined in the JBBR Purchase Agreement), to the extent the Partnership or such Subsidiary has the right to agree to such amendment or termination or the right to
consent to the waiver or relinquishment of such right pursuant to the provisions of the JBBR Purchase Agreement, if such amendment, termination, consent, waiver or relinquishment would be materially adverse to the Partnership unless the
Purchasers entitled to a majority of the Purchased Units consent in writing. 
 ARTICLE VI 

INDEMNIFICATION, COSTS AND EXPENSES 

Section 6.1 Indemnification by the Partnership. The Partnership agrees to indemnify each Purchaser and its Representatives
(collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in
connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, 

  
 20 

 
losses, liabilities, damages or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses
incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any way related to the breach of any of the
representations, warranties or covenants of the Partnership contained herein; provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of such representation or warranty; and
provided further, that no Purchaser Related Party shall be entitled to recover special, consequential (including lost profits) or punitive damages. Notwithstanding anything to the contrary, consequential damages shall not be deemed to include
diminution in value of the Purchased Units, which is specifically included in damages covered by Purchaser Related Parties indemnification. 

Section 6.2 Indemnification by Purchasers. Each Purchaser agrees, severally and not jointly, to indemnify the Partnership and its
respective Representatives (collectively, the “Partnership Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and
causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including, without limitation, the
reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a
result of, arising out of or in any way related to the breach of any of the representations, warranties or covenants (other than Section 5.4) of such Purchaser contained herein; provided that such claim for indemnification relating to a breach
of any representation or warranty is made prior to the expiration of such representation or warranty; and provided further, that no Partnership Related Party shall be entitled to recover special, consequential (including lost profits) or punitive
damages; provided further, (a) that absent fraud, bad faith, gross negligence or willful misconduct on the part of a Purchaser and (b) other than with respect to any breach of the representations and warranties of Sections 4.7 and 4.8, in
no event will such Purchaser be liable under this Section 6.2 for any amount in excess of its Commitment Amount. 
 Section 6.3
Indemnification Procedure. Promptly after any Partnership Related Party or Purchaser Related Party, as the case may be (hereinafter, the “Indemnified Party”), has received notice of any indemnifiable claim hereunder, or the
commencement of any action, suit or proceeding by a third person that the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying
Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party
hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and
settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to
defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all 

  
 21 

 
commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books,
records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying
Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any
additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the
defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (B) if the
defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or
in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select one
separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying
Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party (which consent shall not be unreasonably withheld, delayed or
conditioned), unless the settlement thereof imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and includes a complete release from liability of, the Indemnified Party. 

ARTICLE VII 

MISCELLANEOUS 

Section 7.1 Interpretation of Provisions. Article, Section, Schedule and Exhibit references are to this Agreement, unless otherwise
specified. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from time to time, unless otherwise
specified. The word “including” shall mean “including but not limited to.” Whenever any party has an obligation under the Operative Documents, the expense of complying with that obligation shall be an expense of such party unless
otherwise specified. Whenever any determination, consent or approval is to be made or given by a Purchaser under this Agreement, such action shall be in such Purchaser’s sole discretion unless otherwise specified in this Agreement. If any
provision in the Operative Documents is held to be illegal, invalid, not binding or unenforceable, such provision shall be fully severable and the Operative Documents shall be construed and enforced as if such illegal, invalid, not binding or
unenforceable provision had never comprised a part of the Operative Documents, and the remaining provisions shall remain in full force and effect. The Operative Documents have been reviewed and negotiated by sophisticated parties with access to
legal counsel and shall not be construed against the drafter. 

  
 22 

 Section 7.2 Survival of Provisions. The representations and warranties set forth in
Sections 3.1, 3.2, 3.5, 3.6, 3.18, 3.20 and 3.21 and Sections 4.5, 4.7, 4.8, 4.10 and 4.11 shall survive the execution and delivery of this Agreement and the Closing indefinitely, and the other representations and warranties set forth in this
Agreement shall survive for a period of twelve months following the Closing Date. The covenants made in this Agreement or any other Operative Document shall survive the Closing of the transactions described herein and remain operative and in full
force and effect regardless of acceptance of any of the Purchased Units and payment therefor and repayment, conversion, exercise or repurchase thereof. All indemnification obligations of the Partnership and the Purchasers pursuant to Article VI of
this Agreement shall remain operative and in full force and effect unless such obligations are expressly terminated in writing by the Parties referencing the particular Article or Section, regardless of any purported general termination of this
Agreement. 
 Section 7.3 No Waiver; Modifications in Writing. 

(a) Delay. No failure or delay on the part of any Party in exercising any right, power or remedy hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and are
not exclusive of any remedies that may be available to a Party at law or in equity or otherwise. 
 (b) Specific
Waiver. Except as otherwise provided in this Agreement or the Registration Rights Agreement, no amendment, waiver, consent, modification or termination of any provision of any Operative Document shall be effective unless signed by each of the
Parties or each of the original signatories thereto affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision of any Operative Document, any waiver of any provision of
this Agreement or any other Operative Document and any consent to any departure by the Partnership or any Purchaser from the terms of any provision of any Operative Document shall be effective only in the specific instance and for the specific
purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on any Party in any case shall entitle any Party to any other or further notice or demand in similar or other circumstances.

 Section 7.4 Binding Effect; Assignment. 

(a) Binding Effect. This Agreement shall be binding upon the Partnership, each Purchaser and their respective successors and
permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the Parties to this Agreement and as provided in Article VI and their respective
successors and permitted assigns. 
 (b) Assignment of Rights. Each Purchaser may assign all or any portion of its rights and
obligations under this Agreement to any Affiliate of such Purchaser without the consent of the Partnership by delivery of an agreement to be bound by the provisions of this Agreement and a revised Schedule A but that no such assignment shall
relieve the assigning Purchaser of its obligations to purchase the Purchased Units to be purchased by it without giving effect to such assignment in the event the assignee fails to purchase all or any portion of such Purchased Units

  
 23 

 
on the Closing Date. Except as expressly permitted by this Section 7.4(b), no portion of the rights and obligations under this Agreement of any Purchaser may be transferred except with the
prior written consent of the Partnership (which consent shall not be unreasonably withheld), in which case the assignee shall be deemed to be a Purchaser hereunder with respect to such assigned rights or obligations and shall agree to be bound by
the provisions of this Agreement. 
 Section 7.5 Confidentiality and Non-Disclosure. Notwithstanding anything herein to the
contrary, to the extent a Purchaser has executed a confidentiality agreement in favor of the Partnership, such Purchaser shall continue to be bound by such confidentiality agreement in accordance with the terms thereof as applicable. 

Section 7.6 Communications. All notices and demands provided for hereunder shall be in writing and shall be given by regular mail,
registered or certified mail, return receipt requested, facsimile, courier guaranteeing overnight delivery, electronic mail or personal delivery to the addresses set forth on Schedule 7.6 hereto or to such other address as the
Partnership or such Purchaser may designate in writing. All notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; at the time of transmittal, if sent via electronic email; upon
actual receipt if sent by registered or certified mail, return receipt requested, or regular mail, if mailed; when receipt acknowledged, if sent via facsimile; and upon actual receipt when delivered to a courier guaranteeing overnight delivery. 

Section 7.7 Removal of Legend. In connection with a sale of the Purchased Units by a Purchaser in reliance on Rule 144, the applicable
Purchaser or its broker shall deliver to the transfer agent and the Partnership a customary broker representation letter providing to the transfer agent and the Partnership any information the Partnership deems reasonably necessary to determine that
the sale of the Purchased Units is made in compliance with Rule 144, including, as may be appropriate, a certification that the Purchaser is not an Affiliate of the Partnership and regarding the length of time the Purchased Units have been held.
Upon receipt of such representation letter, the Partnership shall promptly direct its transfer agent to remove the notation of a restrictive legend in such Purchaser’s book-entry account maintained by the transfer agent, including the legend
referred to in Section 4.11, and the Partnership shall bear all costs associated therewith. After any Purchaser or its permitted assigns has held the Purchased Units for such period as will allow such Purchaser to sell such Purchased Units
without volume restrictions or public company information requirements pursuant to any section of Rule 144 (or any similar provision then in effect), if the book-entry account of such Purchased Units still bears the notation of the restrictive
legend referred to in Section 4.11, the Partnership agrees, upon request of the Purchaser or permitted assignee, to take all steps necessary to promptly effect the removal of the legend described in Section 4.11 from the Purchased Units,
and the Partnership shall bear all costs associated therewith, regardless of whether the request is made in connection with a sale or otherwise, so long as such Purchaser or its permitted assigns provide to the Partnership any information the
Partnership deems reasonably necessary to determine that the legend is no longer required under the Securities Act or applicable state laws, including a certification that the holder is not an Affiliate of the Partnership (and a covenant to inform
the Partnership if it should thereafter become an Affiliate and to consent to the notation of an appropriate restriction) and regarding the length of time the Purchased Units have been held. 

  
 24 

 Section 7.8 Entire Agreement. This Agreement and the Registration Rights Agreement are
intended by the Parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the Parties hereto and thereto in respect of the subject matter contained herein and
therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or therein with respect to the rights granted by the Partnership or a Purchaser set forth herein or therein. This Agreement
and the Registration Rights Agreement supersede all prior agreements and understandings between the Parties with respect to such subject matter. 

Section 7.9 Governing Law. This Agreement will be construed in accordance with and governed by the Laws of the State of New
York. 
 Section 7.10 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different
Parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement. 

Section 7.11 Termination. 

(a) Notwithstanding anything herein to the contrary, this Agreement may be terminated on or any time prior to the Closing by the written
consent of the Purchasers entitled to purchase a majority of the Purchased Units based on their Commitment Amounts upon a breach in any material respect by the Partnership of any covenant or agreement set forth in this Agreement; provided, that such
breach would cause the conditions to the Purchasers’ obligations not to be satisfied and such breach is not cured within 20 days after written notice from the Purchasers. 

(b) Notwithstanding anything herein to the contrary, this Agreement shall automatically terminate on or any time prior to the Closing: 

(i) if the Closing shall not have occurred on or before May 18, 2015; 

(ii) if the JBBR Purchase and Sale Agreement shall have been terminated pursuant to its terms; or 

(iii) if a Law shall have been enacted or promulgated, or if any action shall have been taken by any Governmental Authority of
competent jurisdiction that permanently restrains, precludes, enjoins or otherwise prohibits the consummation of the transactions contemplated by this Agreement or the JBBR Purchase Agreement or makes the transactions contemplated by this Agreement
illegal. 
 (c) In the event of the termination of this Agreement as provided in this Section 7.11, (i) any payments of a
Purchaser’s Commitment Amount received by the Partnership shall be returned to such Purchaser and (ii) the Partnership shall pay each Purchaser its respective Commitment Fee, in each case, within two (2) Business Days of such
termination, and this Agreement shall forthwith become null and void. In the event of such termination, there shall be no liability on the part of any Party hereto, except as set forth in Section 5.5 and Article VI and with respect to the
requirement to comply with any confidentiality agreement in favor of the 

  
 25 

 
Partnership; provided further, that nothing contained in this Section 7.11(c) shall require the Partnership to pay a Purchaser its respective Commitment Fee if such Purchaser shall have
breached its obligation to purchase its Purchased Units on the Closing Date in accordance with the terms hereof. 
 Section 7.12
Recapitalization, Exchanges, etc. Affecting the Purchased Units. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all Common Units of the Partnership or any successor or assign of the
Partnership (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange for or in substitution of, the Purchased Units and shall be appropriately adjusted for combinations, recapitalizations and the
like occurring after the date of this Agreement and prior to the Closing.

 Schedule 7.6 

 EXHIBIT A  

Form of Legal Opinion 

Capitalized terms used but not defined herein have the meanings assigned to such terms in the Unit Purchase Agreement (the
“Purchase Agreement”). The Partnership shall furnish to the Purchasers at the Closing an opinion of Vinson & Elkins L.L.P., counsel for the Partnership, and an opinion of the General Counsel of the General Partner, each
addressed to the Purchasers and dated the Closing Date in form satisfactory to the Purchasers, collectively stating that: 
 (i) Each of
the Partnership and the General Partner has been duly formed and is validly existing as a limited partnership or limited liability company, as applicable, in good standing under the laws of the State of Delaware, with full limited partnership or
limited liability company, as the case may be, power and authority (A) to own or lease and to operate its properties and conduct its business, in each case in all material respects as described in the Partnership SEC Documents, and (B) to
enter into and perform its obligations under the Operative Documents. 
 (ii) Except (A) as described in the Partnership SEC Documents
filed prior to the date of the Purchase Agreement or (B) as provided in the Operative Documents or the Arc Logistics Credit Facility or (C) for awards issued under the Arc Logistics GP LLC Long-Term Incentive Plan, there are no preemptive
rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any limited partner interests in the Partnership arising under any agreement filed with the Commission by the Partnership. 

(iii) The Purchased Units to be issued and sold by the Partnership to each Purchaser pursuant to the Purchase Agreement, and the limited
partner interests represented thereby, have been duly authorized, and, when issued and delivered to each Purchaser against payment therefor in accordance with the terms of the Purchase Agreement, will be validly issued, fully paid (to the extent
required by applicable law and the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act). 

(iv) The General Partner is the sole general partner of the Partnership and owns a non-economic general partner interest in the Partnership;
such general partner interest has been duly authorized and validly issued in accordance with the Partnership Agreement; and the General Partner owns such general partner interest free and clear of all Liens (A) in respect of which a financing
statement under the Uniform Commercial Code of the State of Delaware naming the General Partner as debtor is on file in the office of the Secretary of State of the State of Delaware or (B) otherwise known to us, without independent
investigation, other than (1) restrictions on transferability contained in the Partnership Agreement and (2) those created by or arising under the Delaware LP Act. 

(v) Except for the approvals required by the Commission in connection with the Partnership’s obligations under the Registration Rights
Agreement, no consent, approval, authorization, filing with or order of or with any U.S. federal, New York or Delaware court or 

  
 A-1 

 
governmental agency or body having jurisdiction over any of the Partnership Entities or any of their respective properties is required in connection with the execution, delivery and performance
by the Partnership of the Operative Documents, except (A) such as may be required under the state securities or “Blue Sky” Laws (as to which we do not express any opinion), (B) such as have been obtained or made or (C) such
that the failure to obtain or file would not reasonably be expected to have a Partnership Material Adverse Effect. 
 (vi) Assuming the
accuracy of the representations and warranties of each of the Purchasers and the Partnership contained in the Purchase Agreement, the sale and issuance of the Purchased Units by the Partnership to the Purchasers solely in the manner contemplated by
the Purchase Agreement are exempt from the registration requirements of the Securities Act; provided, that, such counsel will express no opinion as to any subsequent sale. 

(vii) The Partnership is not an “investment company” as such term is defined in the Investment Company Act of 1940, as amended. 

(viii) None of the offering, issuance and sale by the Partnership of the Purchased Units, the execution, delivery and performance of the
Operative Documents by the Partnership or the consummation of the transactions contemplated thereby (A) constitutes or will constitute a breach or violation of, or result or will result in an imposition of any lien, charge or encumbrance upon
any property or assets of the Partnership Entities pursuant to any agreement filed or incorporated by reference as an exhibit to the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2013 or the Partnership’s
Quarterly Reports on Forms 10-Q for the quarters ended March 31, 2014, June 30, 2014 and September 30, 2014 (B) constitutes or will constitute a violation of the Partnership Agreement or (C) results or will result in
any violation of the Delaware LP Act, the Delaware LLC Act or U.S. federal law (it being understood that we do not express an opinion in clause (C) with respect to any securities or other anti-fraud laws), except in the case of clauses
(A) or (C) for such breaches, violations, liens, charges or encumbrances as would not reasonably expected be to have a Partnership Material Adverse Effect. 

(ix) Each of the Operative Documents has been duly authorized, executed and delivered by the Partnership and, assuming the due authorization,
execution and delivery by the Purchasers, constitutes a valid and legally binding agreement of the Partnership, enforceable against the Partnership in accordance with its terms; provided, that, with respect to each agreement described
in this paragraph (viii), as the enforceability thereof may be limited by (A) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws relating to or affecting creditors’ rights generally and by general
principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (B) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and
fair dealing.

ARTICLE II 
 REGISTRATION
RIGHTS 
 Section 2.01 Registration. 

(a) Effectiveness Deadline. No later than 30 days following the Closing Date, the Partnership shall prepare and file a registration
statement under the Securities Act to permit the public resale of Registrable Securities then outstanding from time to time as permitted by Rule 415 (or any similar provision then in effect) under the Securities Act with respect to all of the
Registrable Securities (the “Registration Statement”). The Registration Statement filed pursuant to this Section 2.01(a) shall be on such appropriate registration form of the Commission as shall be selected by the
Partnership so long as it permits the continuous offering of the Registrable Securities pursuant to Rule 415 (or any similar provision then in effect) under the Securities Act at the then prevailing market prices. The Partnership shall use its
commercially reasonable efforts to cause the Registration Statement to become effective on or as soon as practicable after the Closing Date. Any Registration Statement shall provide for the resale pursuant to any method or combination of methods
legally available to, and requested by, the Holders of any and all Registrable Securities covered by such Registration Statement. The Partnership shall use its commercially reasonable efforts to cause the Registration Statement filed pursuant to
this Section 2.01(a) to be effective, supplemented and amended to the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holders until all Registrable Securities covered by such
Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”). The Registration Statement when effective (including the documents 

  
 3 

 
incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the
circumstances under which a statement is made). As soon as practicable following the date that the Registration Statement becomes effective, but in any event within two (2) Business Days of such date, the Partnership shall provide the Holders
with written notice of the effectiveness of the Registration Statement. 
 (b) Failure to Go Effective. If the Registration Statement
required by Section 2.01(a) is not declared effective within 90 days after the Closing Date, then each Holder shall be entitled to a payment (with respect to the Purchased Units of each such Holder), as liquidated damages and not as a
penalty, of 0.25% of the Liquidated Damages Multiplier per 30-day period, that shall accrue daily, for the first 60 days following the 90th day, increasing by an additional 0.25% of the Liquidated Damages Multiplier per 30-day period, that shall
accrue daily, for each subsequent 60 days (i.e., 0.5% for 61-120 days, 0.75% for 121-180 days and 1.0% thereafter), up to a maximum of 1.00% of the Liquidated Damages Multiplier per 30-day period (the “Liquidated Damages”). The
Liquidated Damages payable pursuant to the immediately preceding sentence shall be payable within ten (10) Business Days after the end of each such 30-day period. Any Liquidated Damages shall be paid to each Holder in immediately available
funds; provided, however, if the Partnership certifies that it is unable to pay Liquidated Damages in cash because such payment would result in a breach under a credit facility or other debt instrument, then the Partnership may pay the
Liquidated Damages in kind in the form of the issuance of additional Common Units. Upon any issuance of Common Units as Liquidated Damages, the Partnership shall promptly (i) prepare and file an amendment to the Registration Statement prior to
its effectiveness adding such Common Units to such Registration Statement as additional Registrable Securities and (ii) prepare and file a supplemental listing application with the NYSE (or such other market on which the Registrable Securities
are then listed and traded) to list such additional Common Units. The determination of the number of Common Units to be issued as Liquidated Damages shall be equal to the amount of Liquidated Damages divided by the volume-weighted average price of
the Common Units on the NYSE (or such other market on which the Registrable Securities are then listed and traded) over the consecutive ten (10) trading day period ending on the close of trading on the trading day immediately preceding the date
on which the Liquidated Damages payment is due. The accrual of Liquidated Damages to a Holder shall cease at the earlier of (i) the Registration Statement becoming effective or (ii) when such Holder no longer holds Registrable Securities,
and any payment of Liquidated Damages shall be prorated for any period of less than 30 days in which the payment of Liquidated Damages ceases. If the Partnership is unable to cause a Registration Statement to go effective within 90 days after the
Closing Date as a result of an acquisition, merger, reorganization, disposition or other similar transaction, then the Partnership may request a waiver of the Liquidated Damages, and each Holder must individually consent to such request. 

Section 2.02 Piggyback Rights. 

(a) Participation. If the Partnership proposes to file (i) a shelf registration statement other than the Registration Statement
contemplated by Section 2.01(a), (ii) a prospectus supplement to an effective shelf registration statement, other than the Registration Statement 

  
 4 

 
contemplated by Section 2.01(a) and Holders may be included without the filing of a post-effective amendment thereto or (iii) a registration statement, other than a shelf
registration statement, in each case, for the sale of Common Units in an Underwritten Offering for its own account and/or another Person, then as soon as practicable following the engagement of counsel by the Partnership to prepare the documents to
be used in connection with an Underwritten Offering, the Partnership shall give notice (including, but not limited to, notification by electronic mail) of such proposed Underwritten Offering to each Holder (together with its Affiliates) holding at
least $5.0 million of the then-outstanding Registrable Securities (based on the Common Unit Price) and such notice shall offer such Holders the opportunity to include in such Underwritten Offering such number of Registrable Securities (the
“Included Registrable Securities”) as each such Holder may request in writing; provided, however, that if the Partnership has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for
the benefit of the Holders will have an adverse effect on the price, timing or distribution of the Common Units in the Underwritten Offering, then (A) if no Registrable Securities can be included in the Underwritten Offering in the opinion of
the Managing Underwriter, the Partnership shall not be required to offer such opportunity to the Holders or (B) if any Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, then the
amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.02(b). Any notice required to be provided in this Section 2.02(a) to Holders shall be
provided on a Business Day pursuant to Section 3.01 hereof and receipt of such notice shall be confirmed by the Holder. Each such Holder shall then have two (2) Business Days (or one (1) Business Day in connection with any
overnight or bought Underwritten Offering) after notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no written request for inclusion from a Holder is received within the specified
time, each such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten
Offering, the Partnership shall determine for any reason not to undertake or to delay such Underwritten Offering, the Partnership may, at its election, give written notice of such determination to the Selling Holders, and (x) in the case of a
determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering and (y) in the case of a determination to delay
such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s
request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving written notice to the Partnership of such withdrawal at or prior to the time of pricing of such Underwritten Offering. Any Holder may
deliver written notice (an “Opt-Out Notice”) to the Partnership requesting that such Holder not receive notice from the Partnership of any proposed Underwritten Offering; provided, however, that such Holder may later revoke
any such Opt-Out Notice in writing (which Opt-Out Notice shall be effective as to an Underwritten Offering provided the Partnership received such Opt-Out Notice at least ten (10) Business Days prior to the day of pricing of such Underwritten
Offering (or two (2) Business Days prior to the day of pricing in the case of an overnight or bought Underwritten Offering). Following receipt of an Opt-Out Notice from a Holder (unless subsequently revoked), the Partnership shall not be
required to deliver any notice to such Holder pursuant to this Section 2.02(a) and such Holder 

  
 5 

 
shall no longer be entitled to participate in Underwritten Offerings by the Partnership pursuant to this Section 2.02(a). The Holders indicated on Schedule A hereto as having
opted out shall each be deemed to have delivered an Opt-Out Notice as of the date hereof. 
 (b) Priority. If the Managing
Underwriter of any proposed Underwritten Offering advises the Partnership that the total amount of Registrable Securities that the Selling Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such
offering without being likely to have an adverse effect on the price, timing or distribution of the Common Units offered or the market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number
of Registrable Securities that such Managing Underwriter advises the Partnership can be sold without having such adverse effect, with such number to be allocated (i) first, to the Partnership and (ii) second, pro rata among the Selling
Holders who have requested participation in such Underwritten Offering and any other holder of securities of the Partnership having rights of registration that are neither expressly senior nor subordinated to the Registrable Securities (the
“Parity Securities”). The pro rata allocations for each Selling Holder who has requested participation in such Underwritten Offering shall be the product of (a) the aggregate number of Registrable Securities proposed to be sold
in such Underwritten Offering multiplied by (b) the fraction derived by dividing (x) the number of Registrable Securities owned on the Closing Date by such Selling Holder by (y) the aggregate number of Registrable Securities owned on
the Closing Date by all Selling Holders plus the aggregate number of Parity Securities owned on the Closing Date by all holders of Parity Securities that are participating in the Underwritten Offering. 

(c) Termination of Piggyback Registration Rights. Each Holder’s rights under Section 2.02 shall terminate upon such
Holder (together with its Affiliates) ceasing to hold at least $5.0 million of Registrable Securities (based on the Common Unit Price). 

Section 2.03 Delay Rights. 

Notwithstanding anything to the contrary contained herein, the Partnership may, upon written notice to any Selling Holder whose Registrable
Securities are included in the Registration Statement or other registration statement contemplated by this Agreement, suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement or other registration
statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement or other registration statement contemplated by this Agreement but may settle any previously made sales of
Registrable Securities) if (i) the Partnership is pursuing an acquisition, merger, reorganization, disposition, financing or other similar transaction or other corporate transaction and the Partnership determines in good faith that the
Partnership’s ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in the Registration Statement or other registration statement or (ii) the Partnership
has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of the Partnership, would materially adversely affect the Partnership; provided, however, in no event shall the Selling
Holders be suspended from selling Registrable Securities pursuant to the Registration Statement or other registration statement for a period that exceeds an aggregate of 60 days in any 180-day period or 105 days in any 365-day period, in each case,
exclusive of days covered by any lock-up agreement executed by a Selling Holder in connection with any Underwritten 

  
 6 

 
Offering. Upon disclosure of such information or the termination of the condition described above, the Partnership shall provide prompt notice to the Selling Holders whose Registrable Securities
are included in the Registration Statement and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this
Agreement. 
 If (i) the Selling Holders shall be prohibited from selling their Registrable Securities under the Registration Statement
or other registration statement contemplated by this Agreement as a result of a suspension pursuant to the immediately preceding paragraph in excess of the periods permitted therein or (ii) the Registration Statement or other registration
statement contemplated by this Agreement is filed and declared effective but, during the Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded within 30 days by a
post-effective amendment thereto, a supplement to the prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or l5(d) of the Exchange Act, then, until the suspension is lifted or a post-effective amendment,
supplement or report is filed with the Commission, but not including any day on which a suspension is lifted or such amendment, supplement or report is filed and declared effective, if applicable, the Partnership shall pay the Selling Holders an
amount equal to the Liquidated Damages, following the earlier of (x) the date on which the suspension period exceeded the permitted period and (y) the thirty-first (31st) day after the Registration Statement or other registration
statement contemplated by this Agreement ceased to be effective or failed to be useable for its intended purposes, as liquidated damages and not as a penalty (for purposes of calculating Liquidated Damages, the date in (x) or (y) above
shall be deemed the “90th day,” as used in the definition of Liquidated Damages). For purposes of this paragraph, a suspension shall be deemed lifted on the date that notice that the suspension has been terminated is delivered to the
Selling Holders. Liquidated Damages shall cease to accrue pursuant to this paragraph upon the Purchased Units of such Holder becoming eligible for resale without restriction and without the need for current public information under any section of
Rule 144 (or any similar provision then in effect) under the Securities Act, assuming that such Holder is not an Affiliate of the Partnership, and any payment of Liquidated Damages shall be prorated for any period of less than 30 days in which the
payment of Liquidated Damages ceases. 
 Section 2.04 Underwritten Offerings. 

(a) General Procedures. In connection with any Underwritten Offering under this Agreement, the Partnership shall be entitled to select
the Managing Underwriter. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and the Partnership shall be obligated to enter into an underwriting agreement that
contains such representations and warranties, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Selling Holder may participate in such Underwritten
Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required
under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Partnership to and for the benefit of such
underwriters also be made to and for such Selling Holder’s benefit and 

  
 7 

 
that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. If any Selling Holder
disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to the Partnership and the Managing Underwriter; provided, however, that such withdrawal must be made up to and including the time of
pricing of such Underwritten Offering. No such withdrawal shall affect the Partnership’s obligation to pay Registration Expenses. The Partnership’s management may but shall not be required to participate in a roadshow or similar marketing
effort in connection with any Underwritten Offering. 
 (b) No Demand Rights. Notwithstanding any other provision of this Agreement,
no Holder shall be entitled to any “demand” rights or similar rights that would require the Partnership to effect an Underwritten Offering solely on behalf of the Holders. 

Section 2.05 Sale Procedures. In connection with its obligations under this Article II, the Partnership will, as promptly as
reasonably practicable: 
 (a) prepare and file with the Commission such amendments and supplements to the Registration Statement and the
prospectus or prospectus supplement used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect
to the disposition of all Registrable Securities covered by the Registration Statement; 
 (b) if a prospectus or prospectus supplement will
be used in connection with the marketing of an Underwritten Offering from the Registration Statement and the Managing Underwriter notifies the Partnership in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed
information in such prospectus or prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, the Partnership shall use its commercially reasonable efforts to include such information
in such prospectus or prospectus supplement; 
 (c) furnish to each applicable Holder (i) as far in advance as reasonably practicable
before filing the Registration Statement or any other registration statement contemplated by this Agreement or any amendment or supplement thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed
(including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission) and provide each such Holder the opportunity to object to any information pertaining to such Holder
and its plan of distribution that is contained therein and make the corrections reasonably requested by such Holder with respect to such information prior to filing the Registration Statement or such other registration statement or amendment or
supplement thereto and (ii) such number of copies of the Registration Statement or such other registration statement and the prospectus or prospectus supplement included therein and any amendments and supplements thereto as such Holder may
reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement or other registration statement; 

(d) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Registration
Statement or any other registration statement 

  
 8 

 
contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the applicable Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall
reasonably request; provided, however, that the Partnership will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject
it to general service of process in any jurisdiction where it is not then so subject; 
 (e) promptly notify each Selling Holder, at any
time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of the Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or
prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become
effective; and (ii) the receipt of any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Registration Statement
or any other registration statement or any prospectus or prospectus supplement thereto; 
 (f) immediately notify each Selling Holder of
(i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue
statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus or prospectus supplement contained therein, in the light of the
circumstances under which a statement is made); (ii) the issuance or express threat of issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any other registration statement contemplated by
this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the Partnership of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable
securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Partnership agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the
prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances
then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; 

(g) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal
letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable
Securities; 
 (h) in the case of an Underwritten Offering, furnish upon request, (i) an opinion of counsel for the Partnership dated
the date of the closing under the underwriting agreement and (ii) comfort letter(s) dated the pricing date of such Underwritten Offering and letter(s) of like kind dated the date of the closing under the underwriting agreement, in each case,
signed by the 

  
 9 

 
independent public accountants who have certified the Partnership’s financial statements included or incorporated by reference into the applicable registration statement, and each of the
opinion and the comfort letter shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus and any prospectus supplement included therein) as have been customarily covered in
opinions of issuer’s counsel and in accountants’ letters delivered to the underwriters in Underwritten Offerings of securities by the Partnership and such other matters as such underwriters and Selling Holders may reasonably request; 

(i) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make
available to its security holders, as soon as reasonably practicable, an earnings statement which shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder; 

(j) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and
Partnership personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided, that the Partnership need not disclose any non-public information to any such representative
unless and until such representative has entered into a confidentiality agreement with the Partnership; 
 (k) cause all Registrable
Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Partnership are then listed; 

(l) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental
agencies or authorities as may be necessary by virtue of the business and operations of the Partnership to enable the Selling Holders to consummate the disposition of such Registrable Securities; 

(m) provide a transfer agent for all Registrable Securities covered by such registration statement not later than the effective date of such
registration statement; 
 (n) enter into customary agreements and take such other actions as are reasonably requested by the Selling
Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities; and 
 (o) if
requested by a Selling Holder, (i) incorporate in a prospectus or prospectus supplement or post-effective amendment to the Registration Statement or any other registration statement contemplated by this Agreement such information as such
applicable Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being
paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering and (ii) make all required filings of such prospectus or prospectus supplement or post-effective amendment to the Registration Statement
or any other registration statement contemplated by this Agreement after being notified of the matters to be incorporated in such prospectus or prospectus supplement or post-effective amendment. 

  
 10 

 The Partnership will not name a Holder as an underwriter as defined in Section 2(a)(11) of
the Securities Act in any registration statement without such Holder’s consent. If the staff of the Commission requires the Partnership to name any Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act, and such
Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on the Registration Statement, such Holder shall no longer be entitled to receive Liquidated Damages under this Agreement with respect thereto and
the Partnership shall have no further obligations hereunder with respect to Registrable Securities held by such Holder. 
 Each applicable
Holder, upon receipt of notice from the Partnership of the happening of any event of the kind described in subsection (f) of this Section 2.05, shall forthwith discontinue offers and sales of the Registrable Securities by
means of a prospectus or prospectus supplement until such Holder’s receipt of the copies of the supplemented or amended prospectus or prospectus supplement contemplated by subsection (f) of this Section 2.05 or until it
is advised in writing by the Partnership that the use of the prospectus or prospectus supplement may be resumed and has received copies of any additional or supplemental filings incorporated by reference in the prospectus or prospectus supplement,
and, if so directed by the Partnership, such Holder will, or will request the Managing Underwriter, if any, to deliver to the Partnership all copies in their possession or control of the prospectus or prospectus supplement covering such Registrable
Securities current at the time of receipt of such notice. 
 Section 2.06 Cooperation by Holders. The Partnership shall have no
obligation to include Registrable Securities of a Holder in the Registration Statement or any other registration statement contemplated by this Agreement or in an Underwritten Offering pursuant to Section 2.02(a) who has failed to timely
furnish such information that the Partnership determines, after consultation with counsel, is reasonably required in order for such registration statement or prospectus or prospectus supplement, as applicable, to comply with the Securities Act. 

Section 2.07 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder agrees with the Partnership, if requested by
the underwriters, to enter into a customary lock up agreement with underwriters of an Underwritten Offering providing such Holder will not effect any public sale or distribution of Registrable Securities during the 90 calendar day period beginning
on the date of a prospectus or prospectus supplement filed with the Commission with respect to the pricing of any Underwritten Offering, provided that (a) the duration of the foregoing restrictions shall be no longer than the duration of
the shortest restriction generally imposed by the underwriters on the Partnership or the officers, directors or any other Affiliate of the Partnership on whom a restriction is imposed and (b) the restrictions set forth in this
Section 2.07 shall not apply to any Registrable Securities that are included in such Underwritten Offering by such Holder. In addition, this Section 2.07 shall not apply to any Holder that is not entitled to participate in
such Underwritten Offering, whether because such Holder delivered an Opt-Out Notice prior to receiving notice of the Underwritten Offering or because such Holder holds less than $5.0 million of the then-outstanding Registrable Securities. 

  
 11 

 Section 2.08 Expenses. The Partnership will pay all reasonable Registration Expenses as
determined in good faith, including, in the case of an Underwritten Offering, whether or not any sale is made pursuant to such Underwritten Offering. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any
sale of its Registrable Securities hereunder. In addition, except as otherwise provided in Section 2.09 hereof, the Partnership shall not be responsible for legal fees incurred by Holders in connection with the exercise of such
Holders’ rights hereunder. 
 Section 2.09 Indemnification. 

(a) By the Partnership. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this
Agreement, the Partnership will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, managers, employees and agents and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act
and the Exchange Act, and its directors, officers, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees
and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus or prospectus supplement, in light of the circumstances under
which such statement is made) contained in the Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus
supplement contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in
the case of a prospectus or prospectus supplement, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that the Partnership will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use in the Registration Statement or such other
registration statement contemplated by this Agreement, preliminary prospectus or prospectus supplement, free writing prospectus, final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof. Such indemnity
shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person and shall survive the transfer of such securities by such Selling Holder. 

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Partnership, the
General Partner, its directors, officers, employees and agents and each Person, if any, who controls the Partnership within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same
extent as the foregoing indemnity from the Partnership to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of 

  
 12 

 
such Selling Holder expressly for inclusion in the Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or prospectus supplement,
free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar
amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification. 

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability that it
may have to any indemnified party other than under this Section 2.09. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to
participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to
assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.09 for any legal expenses subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the
indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the
indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the
indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable
expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any indemnified party with respect to
which such indemnified party is entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all
liability of, the indemnified party. 
 (d) Contribution. If the indemnification provided for in this Section 2.09 is
held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on
the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an
aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable 

  
 13 

 
Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata
allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph
shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 

(e) Other Indemnification. The provisions of this Section 2.09 shall be in addition to any other rights to indemnification
or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise. 
 Section 2.10 Rule 144
Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, the Partnership agrees to use its commercially
reasonable efforts to: 
 (a) make and keep public information regarding the Partnership available, as those terms are understood and
defined in Rule 144 under the Securities Act, at all times from and after the date hereof; 
 (b) file with the Commission in a timely
manner all reports and other documents required of the Partnership under the Exchange Act at all times from and after the date hereof; and 

(c) so long as a Holder owns any Registrable Securities, furnish, unless otherwise available via EDGAR, to such Holder forthwith upon request
a copy of the most recent annual or quarterly report of the Partnership, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell
any such securities without registration. 
 Section 2.11 Transfer or Assignment of Registration Rights. The rights to cause the
Partnership to register Registrable Securities granted to the Purchasers by the Partnership under this Article II may be transferred or assigned by any Purchaser to one or more transferees or assignees of Registrable Securities;
provided, however, that (a) unless the transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Purchaser, the amount of Registrable Securities transferred or assigned
to such transferee or assignee shall represent at least $5.0 million of Registrable Securities (based on the Common Unit Price), (b) the Partnership is given written notice prior to any said transfer or assignment, stating the name and address
of each such transferee or assignee and identifying the securities 

  
 14 

 
with respect to which such registration rights are being transferred or assigned and (c) each such transferee or assignee assumes in writing responsibility for its portion of the obligations
of such Purchaser under this Agreement. 
 Section 2.12 Limitation on Subsequent Registration Rights. From and after the date hereof,
the Partnership shall not, without the prior written consent of the Holders of a majority of the Registrable Securities, enter into any agreement with any current or future holder of any securities of the Partnership that would allow such current or
future holder to require the Partnership to include securities in any registration statement filed by the Partnership on a basis other than pari passu with, or expressly subordinate to the rights of, the Holders of Registrable Securities
hereunder.

the full extent set forth herein with respect to any and all securities of the Partnership or any successor or assign of the Partnership (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange
for or in substitution of, the Registrable Securities, and shall be appropriately adjusted for combinations, splits, recapitalizations, pro rata distributions and the like occurring after the date of this Agreement. 

Section 3.05 Aggregation of Registrable Securities. All Registrable Securities held or acquired by Persons who are Affiliates of one
another shall be aggregated together for the purpose of determining the availability of any rights and applicability of any obligations under this Agreement. 

Section 3.06 Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if not
impossible, to ascertain, and it is therefore agreed that each such Person, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent
jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to
grant such an injunction or other equitable relief. The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity that such Person may have. 

Section 3.07 Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate
counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

 Section 3.08 Headings. The headings in this Agreement are for convenience of reference
only and shall not limit or otherwise affect the meaning hereof. 
 Section 3.09 Governing Law. THIS AGREEMENT WILL BE CONSTRUED
IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK. 
 Section 3.10 Severability of Provisions. Any provision
of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or
impairing the validity or enforceability of such provision in any other jurisdiction. 
 Section 3.11 Entire Agreement. This
Agreement is intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are
no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein with respect to the rights granted by the Partnership set forth herein. This Agreement supersedes all prior agreements and understandings between
the parties with respect to such subject matter. 
 Section 3.12 Amendment. This Agreement may be amended only by means of a written
amendment signed by the Partnership and the Holders of a majority of the then outstanding Registrable Securities; provided, however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the
consent of such Holder. 
 Section 3.13 No Presumption. If any claim is made by a party relating to any conflict, omission or
ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel. 

Section 3.14 Obligations Limited to Parties to Agreement. Each of the parties hereto covenants, agrees and acknowledges that no Person
other than the Purchasers (and their permitted transferees and assignees) and the Partnership shall have any obligation hereunder and that, notwithstanding that one or more of the Purchasers may be a corporation, partnership or limited liability
company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith or therewith shall be had against any former, current or future director, officer, employee, agent, general or limited partner, manager,
member, stockholder or Affiliate of any of the Purchasers or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement
of any assessment or by any legal or equitable proceeding, or by virtue of any applicable Law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any former,
current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the Purchasers or any former, current or future director, officer, employee, agent, general or limited partner,
manager, member, stockholder or Affiliate of any of the foregoing, as such, for any obligations of the Purchasers under this 

  
 17 

 
Agreement or any documents or instruments delivered in connection herewith or therewith or for any claim based on, in respect of or by reason of such obligation or its creation, except in each
case for any transferee or assignee of a Purchaser hereunder. 
 Section 3.15 Independent Nature of Purchaser’s Obligations. The
obligations of each Purchaser (and their permitted transferees and assignees) under this Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the
obligations of any other Purchaser under this Agreement. Nothing contained herein, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other
kind of group or entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to
independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. 

Section 3.16 Interpretation. All references to “Articles” and “Sections” shall be deemed references to this
Agreement, unless otherwise specified. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from
time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.” Whenever any determination, consent or approval is to be made or given by a Holder under this Agreement, such action shall
be in such Holder’s sole discretion unless otherwise specified.
