future, will provide) the Executive with access to “Trade Secrets” or “Confidential or Proprietary Information” (each, as defined in Section 4(e) hereof), (ii) the Company is engaged in a highly competitive enterprise,

anything in Section 4(c)(i) hereof, the Executive agrees that he owes the Company and such Persons, during the Employment Period and thereafter, a duty to hold all such Information in the strictest confidence and, except with the prior written
authorization of the Company, or as required by law, Governmental Authority or court order, not to disclose such Information to any Person (except as necessary in carrying out the Executive’s duties for the Company consistent with the

(iv) All memoranda, notes, lists, records and other documents or papers (and all copies thereof), including but not limited to, such
items stored in computer memories, on microfiche, electronically, or by any other means, made or compiled by or on behalf of the Executive, or made available to the Executive or in the Executive’s possession concerning or in any way relating to

other Person.

Company or any of its Affiliates, as long as such Person’s engagement by the Executive does not interfere or conflict with the provision of services to the Company or an Affiliate by such Person.

may own or hold, solely as passive investments, securities of Persons engaged in any business that would otherwise be included in Section 4(d)(i) or (ii), as long as with respect to each such investment, the securities held by the Executive do

Further Acknowledgements; Severability.

(v) If any covenant, provision, or agreement contained herein is found by a court having jurisdiction to be unreasonable in duration,
scope or character of restrictions, or otherwise to be unenforceable, such covenant, provision or agreement shall not be rendered unenforceable thereby, but rather the duration, scope or character of restrictions of such covenant, provision or
agreement shall be deemed reduced or modified with retroactive effect to render such covenant, provision or agreement reasonable or otherwise enforceable (as the case may be), and such covenant, provision or agreement shall be enforced as modified.
If the court having jurisdiction will not review the covenant, provision or agreement, the parties hereto shall mutually agree to a revision having an effect as close as permitted by applicable law to the provision declared unenforceable. The
parties hereto agree that if a court having jurisdiction determines, despite the express intent of the parties hereto, that any portion of the covenants, provisions or agreements contained herein are not enforceable, the remaining covenants,
provisions and agreements herein shall be valid and enforceable. Moreover, to the extent that any provision is declared unenforceable, the Company shall have any and all rights under applicable statutes or common law to enforce its rights with
respect to any and all Trade Secrets or Confidential or Proprietary Information or unfair competition by the Executive.

 5. Termination. 

(a) General. The employment of the Executive hereunder (and the Employment Period) shall terminate (or may be terminated) in
accordance with the provisions of this Section 5. 
 (b) Termination Upon Mutual Agreement. The Company and the
Executive may, by mutual written agreement, terminate this Agreement and/or the employment of the Executive (and the Employment Period) at any time. 
 (c) Death or Disability of the Executive. 
 (i) The employment of the
Executive hereunder (and the Employment Period) shall terminate (A) upon the death of the Executive, and (B) at the option of the Company, upon not less than thirty (30) days prior written notice to the Executive or his personal
representative or guardian, if the Executive suffers a “Total Disability” (as defined in Section 5(c)(ii) below). Upon termination for death or Total Disability, the Company shall pay to the Executive’s guardian or personal
representative, as the case may be, in addition to any insurance or disability benefits to which he may be entitled hereunder, the “Accrued Rights” (as defined in Section 5(h) hereof). Notwithstanding the foregoing, to the extent that
the payment of any amount under this Section 5(c) on account of the Executive’s Total Disability is deemed to constitute deferred compensation for purposes of Section 409A of the Code, and such Total Disability does not constitute a
“disability” under Section 409A(a)(2)(C) of the Code, then payment of such amount shall be deferred and made on the first business day following the expiration of the six (6) month period following the Executive’s Separation
from Service (as defined in Section 6(j)). 
 (ii) For purposes of this Agreement, “Total Disability” shall mean
(A) if the Executive is subject to a legal decree of incompetency (the date of such decree being deemed the date on which such disability occurred), (B) the written determination by a physician selected by the Company that, because of a
medically determinable disease, injury or other physical or mental disability, the Executive is unable substantially to perform each of the material duties of the Executive required hereby, and that such disability has lasted for the immediately
preceding ninety (90) days and is, as of the date of determination, reasonably expected to last an additional six (6) months or longer after the date of determination, in each case based upon medically available reliable information, or
(C) qualification by the Executive for benefits under the Company’s long-term disability coverage, if any. 
 (iii)
The date of any legal decree of incompetency or written opinion which is conclusive as to the Total Disability of the Executive shall be deemed the date on which such Total Disability occurred. Any leave on account of illness or temporary disability
which is short of Total Disability shall not constitute a breach of this Agreement by the Executive, and in no event shall any party be entitled to terminate this Agreement for Good Cause due to any such leave. All physicians selected hereunder
shall be board-certified in the specialty most closely related to the nature of the disability alleged to exist. In conjunction with determining mental and/or physical disability for purposes of this Agreement, the Executive consents to any such
examinations which are relevant to a determination of whether he is mentally and/or physically 

  
 12 

 
disabled, and which are required by the aforesaid Company physician, and to furnish such medical information as may be reasonably requested, and to waive any applicable physician patient
privilege that may arise because of such examination. 
 (d) Termination For Good Cause. 

(i) The Company may, upon action of the Board in accordance with Section 5(d)(iii) hereof, terminate the employment of the
Executive (and the Employment Period) at any time for “Good Cause” (as defined below). 
 (ii) For purposes of this
Agreement, “Good Cause” means: 
 (A) A material failure by the Executive to comply with any material
obligation imposed by this Agreement (including, without limitation, any violation of Sections 4 hereof); 
 (B)
The Executive’s continued material failure, after being provided notice specifying the nature of such failure, to comply with a direction of the Executive Chairman or Board with respect to a material act, omission or failure to act on the part
of the Executive; 
 (C) A material breach of the Executive’s fiduciary obligations to the Company;

 (D) Gross negligence, willful misconduct or willful malfeasance by the Executive in connection with the
performance of any material duty for the Company; 
 (E) A violation by the Executive of any legal requirement
or obligation relating to the Company that the Board of Directors, acting in good faith, reasonably determines is likely to have a material adverse impact on the Company (unless the Executive had a reasonable good faith belief that the act, omission
or failure to act in question was not a violation of such legal requirement or obligation); 
 (F) The
Executive’s indictment for, conviction of, or plea of guilty or nolo contendere to a felony involving theft, embezzlement, bribery, kickback, fraud, or dishonesty; 

(G) Theft, embezzlement, bribery, kickback, or fraud by the Executive in connection with the performance of his duties
for the Company; 
 (H) A material failure to comply with any lawful direction of the Executive Chairman or
Board of Directors of the Company; 
 (I) A material violation of the Company’s Standards of Conduct or any
other published Company policy; and 

  
 13 

 (J) Any act, omission or failure to act on the part of the Executive
(including an act, omission or failure to act prior to the commencement of the Executive’s employment with the Company) that results in the inability of the Executive to secure or maintain security clearances necessary or appropriate to
Executive’s position as President and Chie Executive Officer and the conduct of the Company’s business; and 
 (K) The misappropriation of any material business opportunity. 
 “Good
Cause” shall be based only on material matters and not on matters of minor importance. 
 (iii) The Executive may be
terminated for Good Cause only in accordance with a resolution duly adopted by an absolute majority of the entire number of the non-management directors of the Company finding that, in the good faith opinion of the Board, the Executive engaged in
conduct justifying a termination for Good Cause and specifying the particulars of the conduct motivating the Board’s decision to terminate the Executive for Good Cause, and provided that the Executive has been provided the time and opportunity
to cure any act or omission susceptible to cure as hereinafter provided. Such resolution may be adopted by the Board only after the Board has provided to the Executive (A) advance written notice of a meeting of the Board called for the purpose
of determining Good Cause for termination of the Executive, (B) a statement setting forth the alleged grounds for termination, and (C) an opportunity for the Executive, and, if the Executive so desires, the Executive’s counsel to be
heard before the Board. Prior to such meeting of the Board, the Executive shall be given a reasonable time period and opportunity to cure any act or omission which the Board, in its reasonable judgment, determines is susceptible of cure. The action
required to cure the act or omission, and the time period in which cure must be effected, shall be communicated to the Executive in writing. The Board’s delay in providing such notice shall not be deemed to be a waiver of any such Good Cause
nor does the failure to terminate for one Good Cause prevent any later Good Cause termination for a similar or different reason. 
 (e) Termination For Good Reason. 
 (i) The Executive may resign, and
thereby terminate his employment (and the Employment Period), within six (6) months following the initial existence of “Good Reason” (as defined below). Following a Change in Control (as defined below) the Executive may resign for
Good Reason within twelve (12) months following the Change in Control Date. Before resigning, the Executive must provide the Company prior written notice to the Company of his intent to resign to for Good Reason. Such notice must be provided at
least thirty (30) days’ prior to the Executive’s resignation date and must specify in reasonable detail the Good Reason for the Executive’s resignation. The Company shall have a reasonable opportunity to cure any such Good Reason
(that is susceptible of cure) within thirty (30) days after the Company’s receipt of such notice. The Executive’s delay in providing such notice shall not be deemed to be a waiver of any such Good Reason, nor does the failure to
resign for one Good Reason prevent any later Good Reason resignation for a similar or different reason. 

  
 14 

 (ii) For purposes of this Agreement, “Good Reason” means the occurrence of any of
the following circumstances without the Executive’s written consent: 
 (A) A material failure by the
Company to comply with any material obligation imposed by this Agreement; 
 (B) The Executive’s demotion
from the position of President and Chief Executive Officer of the Company (as the parties recognize that any such demotion would be material); 
 (C) A material diminution in the Executive’s authority, duties or responsibilities; 
 (D) A material diminution in the budget over which the Executive retains authority resulting from an action of the Executive Chairman or the Board not directly related to Company performance; or

 (E) A material change in the geographic location at which the Executive must perform his services hereunder,
such that the Company requires the Executive to be based (excluding travel responsibilities in the ordinary course of business) at any office or location more than fifty (50) miles from the current location of the main office of the Company,
which is at 1100 N. Glebe Road, Arlington, Virginia 22201; or 
 (F) A material reduction in the
Executive’s base compensation, or his bonus or benefits opportunities. 
 (iii) Following the date on which a Change of
Control event is legally consummated and legally binding upon the parties (the “Change of Control Date”), Good Reason shall also include the occurrence of any of the following circumstances without the Executive’s written consent:

 (A) The Executive ceases to be an “Executive Officer” (as such term is defined by the Securities
Exchange Act of 1933); or 
 (B) The failure by any successor to the Company to expressly assume all obligations
of the Company under this Agreement. 
 Notwithstanding anything herein to the contrary, in no event shall any action otherwise meeting the
definition of Good Reason under clauses 5(e)(ii) above taken by the Company for Good Cause, constitute, or be deemed to constitute, grounds for Good Reason termination hereunder. 

(f) Resignation other than for Good Reason. The Executive may resign and thereby terminate his employment (and the Employment
Period) under this Agreement at any time upon not less than thirty (30) days’ prior written notice. 

  
 15 

 (g) Termination without Good Cause. The Company may, for any or no reason, terminate
the employment of the Executive (and the Employment Period) under this Agreement at any time upon not less than thirty (30) days’ prior written notice. In the event the Company does not offer to extend Employment Period beyond the third
anniversary of the Effective Date or any Successive Term, then the termination of the Executive’s employment at the end of the Employment Period shall be treated as a termination by the Company without Good Cause for purposes of
Section 5.8(h). 
 (h) Payments Upon Termination. 

(i) Without Good Cause (Not In Connection With A Change In Control). In the event the Executive’s employment is terminated
by the Company without “Good Cause,” or by the Executive for “Good Reason,” prior to, or more than twelve (12) months following a Change in Control Date, then the following provisions shall apply: 

(A) The Company shall pay to the Executive an amount equal to twenty-four (24) months of the Executive’s
“Current Base Salary.” For this purpose, the Executive’s “Current Base Salary” shall be deemed to be the highest Base Salary paid to the Executive at any time during the thirty-six (36) months prior to termination of
the Executive’s employment. Such payment shall be made in a single lump sum within fifteen (15) days following the Executive’s execution of the release provided for in Section 5(h)(iv). 

(B) The Executive shall continue to participate in, and be covered under, the Company’s health care coverage for a
period of one (1) year following the termination of the Executive’s employment (the “Medical Benefits Continuation Period”) on the same basis as other senior executives of the Company. Notwithstanding the foregoing, if the
Executive accepts employment with another entity that provides health care coverage during the Medical Benefits Continuation Period, the Company shall not provide the Executive with health care coverage under this Section (but the Executive shall
retain any rights to continuation coverage that he may have under applicable law). For purposes of the Executive’s continuation coverage rights under Section 601 et. seq. of the Employee Retirement Income Security Act, Section 4980B
of the Code, or any similar state or local law, the continuation period shall be deemed to have commenced as of the beginning of the period for which the Company has agreed to continue benefits following the Executive’s termination of
employment. To the extent that the coverage provided to the Executive is taxable for federal income tax purposes, then the Executive shall pay the full cost of coverage during the Medical Benefits Continuation Period and the Company shall pay the
Executive (in cash, less required withholding) an amount equal to (i) the cost of such coverage, less any amount that would have been payable by the Executive if he were actively employed by the Company, plus (ii) an additional amount
designed to cover all estimated applicable local, state and federal income and payroll taxes imposed on the Executive with respect to such additional payment. Any additional amount payable in accordance with this Section 5(h)(i)(B) shall be
paid to the Executive in cash (less required withholding), on a monthly basis, at the same time that the underlying medical coverage benefit is provided to the Executive. In determining the amount of such payment the

  
 16 

 
Executive shall be deemed to pay federal income tax at the highest marginal rate applicable to individuals in the calendar year in which the payment is made and to pay state and local income
taxes at the highest effective rate in the state or locality in which such payment is taxable. All payments made under this Section 5(h)(i)(B) shall be made in accordance with the provisions of Treas. Reg. §1.409A-3(i)(1). 

(C) The Company shall pay to the Executive, without duplication, (i) the Base Salary through the date of
termination, (ii) any incentive compensation earned but unpaid as of the date of termination for any fiscal year prior to the year in which such termination occurs; (iii) reimbursement for any unreimbursed business expenses properly
incurred by the Executive prior to the date of termination (in accordance with Section 3(c) hereof); and (iv) such employee benefits and accrued leave, if any, to which the Executive is entitled under the employee benefit plans and
arrangements of the Company (in accordance with Section 3(d)(i), (ii) and (iii) hereof) (the amounts described in clauses (i) through (iv) hereof being referred to as the “Accrued Rights”). 

(ii) Without Good Cause (In Connection With A Change In Control). In the event the Executive’s employment is terminated by
the Company without “Good Cause,” or by the Executive for “Good Reason,” within twelve (12) months following a Change in Control, then the following provisions shall apply: 

(A) The Company shall pay to the Executive an amount equal to twenty-four (24) months of the Executive’s
Current Base Salary (as defined in Section 5(h)(i)(A) above). Such payment shall be made in a single lump sum within fifteen (15) days following the Executive’s execution of the release provided for in Section 5(h)(iv).

 (B) The Company shall pay to the Executive a prorated portion of the cash incentive
(including, for this purpose, the annual component and any partial quarterly component) otherwise payable to the Executive for the fiscal year of termination under the Annual Incentive Plan (or any replacement bonus arrangement covering the
Executive). Such amount shall be determined based on Company performance consistent with the cash incentive paid under the Annual Incentive Plan to comparable active executives in good standing who meet expectations and remained on the payroll and
eligible for a bonus. The amount payable shall be determined by multiplying the cash incentive that the Executive would have received had his employment not terminated, by a fraction, the numerator of which is the number of months in the fiscal year
(in the case of the annual component) or fiscal quarter (in the case of the quarterly component) during which Executive was employed (including the month in which the termination occurs) and the denominator of which is twelve (in the case of the
annual component) or three (in the case of the quarterly component). The amount payable to the Executive in accordance with this Section shall be paid in a lump sum on the date on which the Company pays bonuses for the fiscal year of termination to
actively employed senior executives; provided, however, in no event shall such payment be made more than 2 1/2 months following the close of the fiscal year of the Company to which such bonus relates. 

  
 17 

 (C) The Company shall pay to the Executive an amount equal to two
(2) times the average cash incentive (including, for this purpose, any quarterly and annual components) actually paid to the Executive under the Annual Incentive Plan for the five (5) fiscal years immediately preceding the year of
termination. Such payment shall be made in a single lump sum within fifteen (15) days following the Executive’s execution of the release provided for in Section 5(h)(iv). 

(D) The Executive shall be entitled to the payments and benefits described in Section 5(h)(i)(B) and 5(h)(i)(C)
above. 
 (iii) Good Cause. In the event the Executive’s employment is terminated (i) by the Company for Good
Cause, or (ii) by the Executive without Good Reason, then the Company shall have no duty to make any payments or provide any benefits to the Executive pursuant to this Agreement (other than the Accrued Rights). 

(iv) Release. As a condition of receiving the payment provided for in Sections 5(h)(i)(A) and 5(h)(ii)(A) and (C), the Executive
agrees to release the Company and its Affiliates, officers, directors, stockholders, employees, agents, representatives, and successors from and against any and all claims that the Executive may have against any such Person relating to the
Executive’s employment by the Company and the termination thereof, such release to be in form and substance reasonably satisfactory to the Company and shall be furnished by the Company to the Executive within thirty (30) days following the
termination of his employment and executed by the Executive within thirty (30) days following his receipt of the release. 

(i) No Disparaging Comments. During the Employment Period and at all times thereafter, the Executive shall refrain from making any
disparaging remarks about the businesses, services, products, members, managers, officers, directors, employees or other personnel of the Company and/or its Affiliates. 
 6. Miscellaneous. 
 (a) ARBITRATION. SUBJECT TO THE RIGHTS UNDER
SECTION 4(e) TO SEEK INJUNCTIVE OR OTHER EQUITABLE RELIEF AS SPECIFIED IN THIS AGREEMENT, ANY DISPUTE BETWEEN THE PARTIES HERETO ARISING UNDER OR RELATING TO THIS AGREEMENT (INCLUDING, BUT NOT LIMITED TO, THE AMOUNT OF DAMAGES, THE NATURE OF THE
EXECUTIVE’S TERMINATION OR THE CALCULATION OF ANY BONUS OR OTHER AMOUNT OR BENEFIT DUE) SHALL BE RESOLVED IN ACCORDANCE WITH THE MODEL EMPLOYMENT ARBITRATION PROCEDURES OF THE AMERICAN ARBITRATION ASSOCIATION. ANY RESULTING HEARING SHALL BE
HELD IN THE JURISDICTION APPROPRIATE TO THE PRINCIPAL LOCATION AT WHICH THE EXECUTIVE PROVIDED HIS SERVICES HEREUNDER (CURRENTLY ARLINGTON, VIRGINIA). THE RESOLUTION OF ANY DISPUTE ACHIEVED THROUGH SUCH ARBITRATION SHALL BE BINDING AND ENFORCEABLE
BY A COURT OF COMPETENT JURISDICTION. COSTS AND FEES INCURRED IN CONNECTION WITH SUCH ARBITRATION SHALL BE BORNE BY THE PARTIES AS DETERMINED BY THE ARBITRATION. 

  
 18 

 (b) Indemnification and Insurance. The Company and the Executive are parties to an
Indemnification Agreement dated August 6, 2011 (the “Indemnification Agreement”), which shall remain in full force and effect accordance with, and subject to, its terms. During the Employment Period, the Company shall provide
directors’ and officers’ liability insurance covering the Executive and errors and omissions insurance covering the activities of the Executive in the exercise of the Executive’s duties in the interest of the Company comparable to and
no less favorable to the Executive than similar insurance provided by the Company to or for other senior executives of the Company. 
 (c) Entire Agreement. This Agreement and the agreements, schedules and exhibits incorporated herein by reference contain the entire agreement between the Executive and the Company with respect to
the subject matter hereof, and supersede any and all prior understandings or agreements, whether written or oral, including, without limitation, the Severance Compensation Agreement between the Company and the Executive. However, this Agreement does
not affect or supersede the terms of the SERP or the Indemnification Agreement. No modification or addition hereto or waiver or cancellation of any provision hereof shall be valid except by a writing signed by the party to be charged therewith.

 (d) Waiver. No waiver by either party hereto of any of the requirements imposed by this Agreement on, or any breach of
any condition or provision of this Agreement to be performed by, the other party shall be deemed a waiver of a similar or dissimilar requirement, provision or condition of this Agreement at the same or any prior or subsequent time. Any such waiver
shall be express and in writing, and there shall be no waiver by conduct. Pursuit by either party of any available remedy, either in law or equity, or any action of any kind, does not constitute waiver of any other remedy or action. Such remedies
are cumulative and not exclusive. 
 (e) Governing Law. The validity, interpretation, construction and performance of
this Agreement shall be governed by the laws of the Commonwealth of Virginia applicable to contracts executed by, and to be performed entirely within, said State, without regard to principles of conflict of laws. 

(f) Successors and Assigns; Binding Agreement. The rights and obligations of the parties under this Agreement shall be binding
upon and inure to the benefit of the parties hereto and their heirs, personal representatives, successors and permitted assigns. This Agreement is a personal contract, and, except as specifically set forth herein, the rights and interests of the
Executive herein may not be sold, transferred, assigned, pledged or hypothecated by any party without the prior written consent of the others. As used herein, the term “successor” as it relates to the Company, shall include, but not be
limited to, any successor by way of merger, consolidation, sale of all or substantially all of such Person’s assets or equity interests. The Company may only assign this Agreement with the Executive’s consent. 

(g) Representation by Counsel. Each of the parties hereto acknowledges that (i) it or he has read this Agreement in its
entirety and understands all of its terms and conditions, (ii) it or he has had the opportunity to consult with any individuals of its or his choice regarding its or his agreement to the provisions contained herein, including legal counsel of
its or his choice, and any decision not to was his or its alone, and (iii) it or he is entering into this Agreement of its or his own free will, without coercion from any source. 

  
 19 

 (h) Interpretation. The parties and their respective legal counsel actively
participated in the negotiation and drafting of this Agreement, and in the event of any ambiguity or mistake herein, or any dispute among the parties with respect to the provisions hereto, no provision of this Agreement shall be construed
unfavorably against any of the parties on the ground that he, it, or his or its counsel was the drafter thereof. 
 (i)
Notices. All notices and communications hereunder shall be in writing and shall be deemed properly given and effective when received, if sent by facsimile or telecopy, or by postage prepaid by registered or certified mail, return receipt
requested, or by other delivery service which provides evidence of delivery, as follows: 
 If to the Company, to: 

CACI International Inc 
 1100 N. Glebe Road 
 16th Floor 

Arlington, Virginia 22201 
 Attention: General Counsel 
 If to the Executive, to: 

Daniel D. Allen 

20250 Island View Court 
 Potomac Falls, VA 20165 
 or to such other address as one party may provide in writing to the
other party from time to time. 
 (j) Compliance with Section 409A. To the extent that Section 409A of the Code
applies to any election or payment required under this Agreement, such payment or election shall be made in conformance with the provisions of Section 409A of the Code. Certain provisions of this Agreement are intended to constitute a
short-term deferral under Treas. Reg. §1.409A-1(b)(4) or a separation pay arrangement that does not provide for the deferral of compensation subject to Section 409A of the Code (under the short-term deferral exception). In order for the
short-term deferral exception to apply, payments must be completed within two and, if a half months after the close of the year in which Executive’s separation from service occurs. If any such provision is subject to more than one
interpretation or construction, such ambiguity shall be resolved in favor of that interpretation or construction which is consistent with such provisions not being subject to the provisions of Section 409A. The remaining provisions of this
Agreement are intended to comply with the provisions of Section 409A of the Code (to the extent applicable) and, to the extent that Section 409A applies to any provision of this Agreement and such provision is subject to more than one
interpretation or construction, such ambiguity shall be resolved in favor of that interpretation or construction which is consistent with the provision complying with the 

  
 20 

 
applicable provisions of Section 409A of the Code (including, but not limited to the requirement that any payment made on account of the Executive’s separation from service (within the
meaning of Section 409A(a)(2)(A)(i) of the Code and the regulations issued thereunder) (“Separation from Service”), shall not be made earlier than the first business day of the seventh month following the Executive’s Separation
from Service, or if earlier the date of death of the Executive). Any payment that is delayed in accordance with the foregoing sentence shall be made on the first business day following the expiration of such six (6) month period. 

(k) Withholding Taxes. All amounts payable hereunder shall be subject to the withholding of all applicable taxes and deductions
required by any applicable law. 
 (l) Tax Consequences of Payments. Executive understands and agrees that the Company
makes no representations as to the tax consequences of any compensation or benefits provided hereunder (including, without limitation, under Section 409A of the Code, if applicable). Executive is solely responsible for any and all income,
excise or other taxes imposed on Executive with respect to any and all compensation or other benefits provided to Executive. 

(m) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original and all of
which together shall constitute one and the same instrument. 
 (n) Duration. Notwithstanding the Employment Term
hereunder, this Agreement shall continue for so long as any obligations remain under this Agreement. 
 (o) Section
References. The word Section herein shall refer to provisions of this Agreement unless expressly indicated otherwise. 
 (p)
Captions. Section headings are for convenience only and shall not be considered a part of this Agreement. 
 IN WITNESS
WHEREOF, the parties have duly executed this Agreement, intending it as a document under seal, as of the date first above written.

	 	(i)	if the Final Consideration Adjustment Amount as finally determined pursuant to this Section 2.4 is a positive amount, the Partnership shall promptly deliver
to the Contributing Parties, by wire transfer of immediately available funds to the account designated by the Contributing Parties, an amount equal to the Final Consideration Adjustment Amount; 

 

	 	(ii)	if the Final Consideration Adjustment Amount as finally determined pursuant to this Section 2.4 is a negative number, then the Contributing Parties shall
promptly deliver to the Partnership Parties, by wire transfer of immediately available funds to the account designated by the Partnership Parties an amount equal to the lesser of absolute value of the Final Consideration Adjustment Amount or the
Cash Consideration. If the absolute value of the Final Consideration Adjustment Amount is greater than the Cash Consideration, then the Partnership Agreement Amendment will address the satisfaction of such difference; and 

  
 13 

	 	(iii)	if the Final Consideration Adjustment Amount as finally determined pursuant to this Section 2.4 is equal to zero, neither the Partnership nor the
Contributing Parties shall have any further obligation under this Section 2.4.

	 	(a)	 the execution, delivery and performance of this Agreement by each of the Contributing Parties does not, and the execution, delivery and performance of

Contributed Interest to the Partnership. The Contributed Interest is not subject to any agreements or understandings with respect to the voting or transfer of any of the Contributed Interest (except the contribution of the Contributed Interest
contemplated by this Agreement and restrictions 

  
 16 

	 	
under applicable federal and state securities laws). The Contributed Interest has been duly authorized and is validly issued, fully paid (to the extent required under the WOL LLC Agreement) and

LLC Agreement, this Agreement or the CCA Agreement. 

 3.5 Financial Information; Undisclosed Liabilities. 

 

	 	(a)	Disclosure Schedule 3.5(a) sets forth a true and complete copy of the unaudited balance sheets as of December 31, 2010 and 2011 and as of June 30,
2012, and statements of income for the fiscal years ended December 31, 2010 and 2011 and for the six-month periods ended June 30, 2011 and 2012 for the Contributed Entities on a consolidated basis, after reflecting the adjustments set
forth on Disclosure Schedule 3.5(a) (collectively referred to as the “Financial Statements”). The Financial Statements present fairly in all material respects the financial position of the Contributed Entities as of the dates
thereof and the results of operations of the Contributed Entities for the periods presented. Except as set forth in Disclosure Schedule 3.5(a), there are no off-balance sheet arrangements that have or are reasonably likely to have a
Contributed Entity Material Adverse Effect. The Financial Statements have been prepared in accordance with GAAP consistently applied throughout the periods presented, except that the Financial Statements reflect the transactions set forth on
Disclosure Schedule 3.5(a) and do not include any notes. Except as required by GAAP, there were no changes in the method of application of the Contributed Entities’ accounting policies or changes in the method of applying the Contributed
Entities’ use of estimates in the preparation of the Financial Statements as compared with past practice. 

  
 17 

	 	(b)	There are no liabilities or obligations of the Contributed Entities of any nature (whether known or unknown and whether accrued, absolute, contingent or otherwise) and
there are no facts or circumstances that would reasonably be expected to result in any such liabilities or obligations, whether arising in the context of federal, state or local judicial, regulatory, administrative or permitting agency proceedings,
other than (i) liabilities or obligations accrued in the Financial Statements, (ii) current liabilities incurred in the ordinary course of business since January 1, 2012, (iii) liabilities or obligations set forth on
Disclosure Schedule 3.5(b), and (iv) liabilities or obligations (whether known or unknown and whether accrued, absolute, contingent or otherwise) that would not, individually or in the aggregate, reasonably be expected to have a
Contributed Entity Material Adverse Effect. 

 3.6 Internal Controls. 

The system of internal controls over financial reporting to which the Contributed Entities are subject is sufficient to provide reasonable assurance
(a) that transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP consistently applied, (b) that transactions are executed only in accordance with the authorization of management, and
(c) regarding the prevention or timely detection of the unauthorized acquisition, use or disposition of the assets of such Contributed Entities. 
 3.7 Real Property; Rights-of-Way. 
  

	 	(a)	 Each of the Contributed Entities has (i) good and marketable title to all real property it owns in fee simple and the improvements located thereon
(the “Owned Real Property”), (ii) valid leasehold estate in all real property and buildings held under lease by any of the Contributed Entities (the “Leased Real Property”) and (iii) good title to all
tangible personal property that comprises the Contributed Entities Assets, all of which Owned Real Property, Leased Real Property and personal property are sufficient for the operation of such Contributed Entities’ olefins business as presently
conducted, free and clear of all Liens except Permitted Liens, except as would not reasonably be expected to have a Contributed Entity Material Adverse Effect; provided, that, with respect to any real property and buildings held under lease
by any Contributed Entity, such real property and buildings are held under valid and subsisting and enforceable leases with such exceptions as do not materially interfere with the use of the properties of the Contributed Entities taken as a whole as
they have been used consistent with past practice of the Contributed Entities. With respect to the Leased Real Property, except to the extent described to the contrary on Disclosure Schedule 3.7(a), all leases and subleases are in full force
and effect and the Contributed Entities have not received any written 

  
 18 

	 	
notice of a breach or default thereunder, whether actual or alleged and, to the Knowledge of the Contributing Parties, no event has occurred that, with notice or lapse of time or both, would
constitute a breach or default under any such lease or sublease, except for any such breaches or defaults that would not, individually or in the aggregate, reasonably be expected to have a Contributed Entity Material Adverse Effect.

  

	 	(b)	Each of the Contributed Entities has such consents, easements, rights-of-way, permits and licenses from each Person, including Governmental Authorities (collectively,
the “Rights-of-Way” and together with the Owned Real Property and Leased Real Property, the “Real Property”) as are sufficient to conduct the Contributed Entities’ olefins business substantially in accordance
with past practice, except for such Rights-of-Way the absence of which have not had, and would not reasonably be expected to have, individually or in the aggregate, a Contributed Entity Material Adverse Effect. With respect to the Rights-of-Way,
except to the extent described to the contrary on Disclosure Schedule 3.7(b), (i) each of the Contributed Entities has fulfilled and performed all its material obligations thereunder and no default or other event has occurred that
allows, or after notice or lapse of time would allow, revocation or termination thereof or would result in any impairment of the rights of the holder of any of the Rights-of-Way, except for such revocations, terminations and impairments that have
not had, and would not reasonably be expected to have, individually or in the aggregate, a Contributed Entity Material Adverse Effect; and (ii) none of the Rights-of-Way contains any restriction that is materially burdensome to the Contributed
Entities, taken as a whole. 

  

	 	(c)	Except as set forth on Disclosure Schedule 3.7(c), (i) (A) there are no pending proceedings or actions to modify the zoning classification of, or to
condemn or take by power of eminent domain or other similar proceeding, all or any of the Contributed Entities Assets and (B) neither Contributing Party has any Knowledge of any such threatened proceeding or action, which (in either case), if
pursued, would reasonably be expected to have a Contributed Entity Material Adverse Effect, (ii) to the extent located in jurisdictions subject to zoning, the Real Property is properly zoned for the existence, occupancy and use of all of the
improvements located thereon, except as would not reasonably be expected to have a Contributed Entity Material Adverse Effect, and (iii) none of such improvements are subject to any conditional use permits or “permitted non-conforming
use” or “permitted non-conforming structure” classifications or similar permits or classifications, except as would not, either currently or in the case of a rebuilding of or additional construction of improvements, reasonably be
expected to have a Contributed Entity Material Adverse Effect. 

  
 19 

 3.8 Litigation; Laws and Regulations. 
 Except as set forth on Disclosure Schedule 3.8:

Knowledge, pending or threatened investigations by any Governmental Authority against the Contributed Entities, except in each case, for those items that would not, individually or in the aggregate, reasonably be expected to have a Contributed
Entity Material Adverse Effect. 

  

	 	(b)	None of the Contributing Parties or the Contributed Entities is in violation of or in default under any Applicable Law, except as would not, individually or in the
aggregate, reasonably be expected to have a Contributed Entity Material Adverse Effect.

	 	(a)	To the Knowledge of the Contributing Parties, except as would not reasonably be expected to have a Contributed Entity Material Adverse Effect, (i) all Tax Returns

which come from either a crude oil refinery or a natural gas processing facility, or other items of income as to which counsel has opined or will opine are “qualifying income” within the meaning of Section 7704(d) of the Code.

“Associated Employees”) are covered by a collective bargaining agreement. Except as would not result in any liability to the Partnership Parties or the Contributed Entities or as set forth on Disclosure Schedule 3.15(a), there are
no facts or circumstances that have resulted or would reasonably be expected to result in a claim on behalf of an individual or a class in excess of $250,000 for unlawful discrimination, unpaid overtime or any other violation of state or federal

equitable obligation to establish, any compensation or benefit plan, agreement, program or policy (whether written or oral, formal or informal) for the benefit of any present or former directors, officers, employees, agents, consultants or other
similar representatives, including, but not limited to, any “employee benefit plan” as defined in section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) (the foregoing are
hereinafter collectively referred to as “Plans”). All Plans in which Associated Employees participate are sponsored or maintained by a Contributing Party or its Affiliate. 

 

	 	(c)	Except as would not result in any liability to the Partnership Parties or the Contributed Entities, (i) each Plan in which Associated Employees participate and
that is intended to be qualified under Section 401(a) of the Code is and has been so qualified in form, and (ii) each Plan in which Associated Employees participate is and has been operated and maintained in material compliance with its

	 	(d)	 With respect to any Plan that the Contributing Parties (or any entity treated as a single employer with a Contributing Party for purposes of
Section 414 of the Code or Section 4001(a)(14) of ERISA (the “Contributing Parties Aggregated Group”)) has maintained within the last six years or has had any obligation to contribute to within the past six years,
(i) except for an event described in Section 4043(c)(3) of ERISA and except for an event that would not impose any liability on the Partnership Parties or the Contributed Entities, there has been no “reportable event,” as
that term is defined in Section 4043 of ERISA, for which the thirty (30) day reporting requirement has not been waived, and the transactions contemplated by this Agreement will not result in such a “reportable event” for
which a waiver does not apply, (ii) none of the Contributed Entities, the Contributing Parties or any member of the Contributing Parties 

  
 25 

	 	
Aggregated Group has incurred any direct or indirect liability under Title IV of ERISA other than liability for premiums to the Pension Benefit Guaranty Corporation that have been timely paid and
other than any liabilities for which the Contributed Entities have no direct or indirect responsibility or obligation, and (iii) there does not exist any accumulated funding deficiency within the meaning of Section 412 of the Code or
Section 302 of ERISA, whether or not waived that, in either case, would give rise to a Lien on any of the Contributed Entities’ assets or that would reasonably be expected to result in a WOL Material Adverse Effect. None of the Contributed
Entities, the Contributing Parties or any member of the Contributing Parties Aggregated Group contributes to, or has an obligation to contribute to, and has not within six years prior to the Closing Date contributed to, or had an obligation to
contribute to, a “multiemployer plan” within the meaning of Section 3(37) of ERISA (x) that is, or is reasonably expected to be in “critical” or “endangered” status as defined in Section 432 of the
Code or Section 305 of ERISA, or (y) in respect of which a Contributed Entity, a Contributing Party or any member of the Contributing Parties Aggregated Group has or may reasonably be expected to incur any withdrawal liability (as defined
in Section 4201 of ERISA). 

  

	 	(e)	The present value of the aggregate benefit liabilities under all of the Plans of Williams or its Affiliates subject to Title IV of ERISA (other than multiemployer

valuation report for such plan year, did not exceed by more than $300 million the aggregate current value of the assets of all such Title IV Plans allocable to such benefit liabilities. No Title IV Plan is, or is reasonably expected to be within one
year immediately following the Closing, in “at-risk” status (as defined in Section 303(i)(4) of ERISA or Section 430(i)(4) of the Code). The term “benefit liabilities” has the meaning specified in section 4001 of ERISA
and the terms “current value” and “present value” have the meaning specified in section 3 of ERISA. 

  

	 	(f)	Except as would not result in any liability to the Contributed Entities, the execution and delivery of this Agreement and the consummation of the transactions

the incurrence or acceleration of any other obligation related to the Plans or to any employee or former employee of any Contributing Party or any of its Affiliates.

 There is no labor strike, or other material dispute, slowdown or stoppage pending or, to the Knowledge of the Contributing Parties, threatened against any Contributing Party or any Contributed Entity with
respect to any employee that will be providing services to such Contributed Entities. 
 3.17 Transactions with Affiliates. 

Except as otherwise contemplated in this Agreement or as set forth on Disclosure Schedule 3.17, none of the Contributed Entities is a party to, and
immediately after Closing will not be party to, any agreement, contract or arrangement between such Contributed Entity, on the one hand, and any of its Affiliates, on the other hand, other than those entered into (i) in the ordinary course of
business relating to the provision of natural gas liquids and/or olefins processing, transportation, marketing or storage service, the interconnection of the respective pipeline systems of the Contributed Entities and their Affiliates, the provision

Contributed Entities. 
 3.18 Insurance. 
 Except as set forth in Disclosure Schedule 3.18, the Contributed Entities Assets are covered by, and immediately after the Closing will be insured under, insurance policies underwritten by
reputable insurers that include coverages and related limits and deductibles that are customary for companies of similar size and complexity as the Contributing Parties in the natural gas liquids and/or olefins transportation, processing, marketing
and storage industry, and consistent with past practice. All such insurance policies are in full force and effect, and all premiums due and payable on such policies will be paid through the date of Closing. No notice of cancellation of, or
indication of an intention not to renew, any such insurance policy has been received by any Contributing Party other than in the ordinary course of business.  
 3.19 Intellectual Property Rights. 
 Each Contributed Entity owns or has the right to use
all Intellectual Property necessary for or used in the conduct of its business as currently conducted by it, and its products and services do not infringe upon, misappropriate or otherwise violate any Intellectual Property of any third party. All
Intellectual Property owned by any Contributed Entity, if any, is free and clear of all Liens (other than Permitted Liens). Neither the execution or delivery of this Agreement, nor the consummation of the transactions contemplated hereby will, with
or without notice or lapse of time, result in, or give any other Person the right or option to cause or declare, a breach or termination of, or cancellation or reduction in, rights of any Contributed Entity under any contract providing for the
license of any Intellectual Property to such Contributed Entity, except for any such terminations, cancellations or reductions that, individually or in the aggregate, would not have a Contributed Entity Material Adverse Effect. There is no
Intellectual Property-related action, suit, proceeding, hearing, investigation, notice or complaint pending or threatened 

  
 27 

 
by any third party before any court or tribunal (including, without limitation, the United States Patent and Trademark Office or equivalent authority anywhere in the world) relating to any
Contributed Entity or its operations, nor has any claim or demand been made by any third party that alleges any infringement, misappropriation or violation of any Intellectual Property of any third party, or unfair competition or trade practices by
any of the Contributed Entities. Except as would not result in a Contributed Entity Material Adverse Effect, the Contributed Entities have taken reasonable measures to protect the confidentiality of all material trade secrets.

Contributing Parties or the Contributed Entities is, nor immediately after the Closing will be, subject to regulation under the Investment Company Act of 1940, as amended. 
 3.21 Brokerage Arrangements. 
 The Contributing Parties have not entered (directly or
indirectly) into any agreement with any Person that would obligate any Contributing Party to pay any commission, brokerage or “finder’s fee” or other similar fee in connection with this Agreement, the CCA Agreement or the transactions
contemplated hereby or thereby. 
 3.22 Books and Records. 
 Accurate copies of the respective books of account, minute books, stock or other equity record books of each Contributed Entity have been made available for inspection to the Partnership Parties.

Common Units in the Private Equity Placement and the Additional General Partner Units solely for the purpose of investment and not with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act
or state securities laws. The Contributing Parties acknowledge that the Common Units issued in the Private Equity Placement and the Additional General Partner Units will not be registered under the Securities Act or any applicable state securities

exemption therefrom and pursuant to state securities laws and regulations as applicable. The Contributing Parties acknowledge that each certificate representing the Common Units issued in the Private Equity Placement shall bear a legend in
substantially the following form: 
 THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF WILLIAMS PARTNERS L.P. THAT THIS SECURITY MAY

WILLIAMS PARTNERS GP LLC, THE GENERAL PARTNER OF WILLIAMS PARTNERS L.P., MAY IMPOSE ADDITIONAL RESTRICTIONS ON THE TRANSFER OF THIS SECURITY IF IT RECEIVES AN OPINION OF COUNSEL THAT SUCH RESTRICTIONS ARE NECESSARY TO AVOID A SIGNIFICANT RISK OF

ENTERED INTO THROUGH THE FACILITIES OF ANY NATIONAL SECURITIES EXCHANGE ON WHICH THIS SECURITY IS LISTED OR ADMITTED TO TRADING.

the Partnership Parties of any covenant with respect to Taxes in this Agreement. 

  

	 	(c)	 Whenever it is necessary for purposes of this ARTICLE 7 to determine the amount of any Taxes imposed on or incurred by or with respect to the
Contributed Entities or the Contributed Entities Assets for a taxable period beginning before and ending after the Closing Date which is allocable to the period prior to and including the Closing Date, the determination shall be made, in the case of
property or ad valorem taxes or franchise taxes (which are measured by, or based solely upon capital, debt or a combination of capital and debt), on a per diem basis and, in the case of

  
 39 

	 	
other Taxes, by assuming that such pre-Closing Date period constitutes a separate taxable period applicable to the Contributed Entities and by taking into account the actual taxable events
occurring during such period (except that exemptions, allowances and deductions for a taxable period beginning before and ending after the Closing Date that are calculated on an annual or periodic basis, such as the deduction for depreciation, shall
be apportioned to the period prior to and including the Closing Date ratably on a per diem basis). Notwithstanding anything to the contrary herein, any franchise tax paid or payable with respect to the Contributed Entities or the Contributed
Entities Assets shall be allocated to the taxable period during which the income, operations, assets or capital comprising the base of such tax is measured, regardless of whether the right to do business for another taxable period is obtained by the
payment of such franchise tax. 

  

	 	(d)	If any of the Partnership Parties or their Affiliates receives a refund of any Taxes that any of the Contributing Parties are responsible for hereunder, or if the
Contributing Parties or their Affiliates receive a refund of any Taxes that any of the Partnership Parties is responsible for hereunder, the party receiving such refund shall, within ninety (90) days after receipt of such refund, remit it to
the party who has responsibility for such Taxes hereunder. The parties shall cooperate in order to take all necessary steps to claim any such refund. 

 7.2 Tax Returns. 
  

	 	(a)	The Contributing Parties shall cause to be included in the consolidated federal income Tax Returns (and the state income Tax Returns of any state that permits
consolidated, combined or unitary income Tax Returns, if any) of the Williams Tax Group for all periods ending on or before the Closing Date, all the items of income, gain, loss, deduction and credit (“Tax Items”) with respect to
the Contributed Entities or the Contributed Entities Assets which are required to be included therein, shall cause such Tax Returns to be timely filed with the appropriate Taxing Authorities, and shall be responsible for the timely payment (and
entitled to any refund) of all Taxes due with respect to the periods covered by such Tax Returns. 

  

	 	(b)	With respect to any Tax Return covering a taxable period ending on or before the Closing Date that is required to be filed after the Closing Date with respect to the
Contributed Entities or the Contributed Entities Assets that is not described in Section 7.2(a) above, the Contributing Parties shall cause such Tax Return to be prepared, cause to be included in such Tax Return all Tax Items required to
be included therein, cause such Tax Return to be filed timely with the appropriate Taxing Authority, and be responsible for the timely payment (and entitled to any refund) of all Taxes due with respect to the period covered by such Tax Return.

  
 40 

	 	(c)	With respect to any Tax Return covering a taxable period beginning on or before the Closing Date and ending after the Closing Date that is required to be filed after
the Closing Date with respect to the Contributed Entities or the Contributed Entities Assets, the Contributing Parties shall cause such Tax Return to be prepared, cause to be included in such Tax Return all Tax Items required to be included therein,
furnish a copy of such Tax Return to the Partnership Parties, cause such Tax Return to be filed timely with the appropriate Taxing Authority, and be responsible for the timely payment of all Taxes due with respect to the period covered by such Tax
Return (but shall have a right to recover the amount of Tax Losses attributable to the portion of the taxable period occurring after the Closing Date pursuant to Section 7.1(b)). 

 

	 	(d)	With regard to any Tax Return not yet filed for any taxable period that begins before the Closing Date with respect to the Contributed Entities or the Contributed
Entities Assets, the Contributing Parties shall use commercially reasonable efforts to cause such Tax Return to be prepared in accordance with past Tax accounting practices used with respect to the Tax Returns in question (unless such past practices
are no longer permissible under the Applicable Law), and to the extent any items are not covered by past practices, in accordance with reasonable tax accounting practices selected by the filing party with respect to such Tax Return under this
Agreement with the consent (not to be unreasonably withheld or delayed) of the non-filing party. 

 7.3 Transfer Taxes.

 The Contributing Parties shall file all necessary Tax Returns and other documentation with respect to all transfer, documentary, sales, use,
stamp, registration and other similar Taxes and fees arising out of or in connection with the transactions effected pursuant to this Agreement (the “Transfer Taxes”) and shall be liable for and shall timely pay such Transfer Taxes.
If required by applicable Law, the Partnership Parties shall, and shall cause their Affiliates to, join in the execution of any such Tax Returns and other documentation. 
 7.4 Survival. 
 Anything to the contrary in this Agreement notwithstanding, the
representations, warranties, covenants, agreements, rights and obligations of the parties hereto with respect to any Tax matter covered by this Agreement shall survive the Closing and shall not terminate until the expiration of the applicable
statutes of limitations (including all periods of extension and tolling) applicable to such Tax matter. 
 7.5 Conflict. 

In the event of a conflict between the provisions of this ARTICLE 7 and any other provisions of this Agreement, the provisions of this ARTICLE 7 shall
control. 

  
 41 

 ARTICLE 8 
 TERMINATION 
 8.1 Events of Termination. 

This Agreement may be terminated at any time prior to the Closing Date: 
  

	 	(a)	by mutual written consent of all parties hereto; 

  

	 	(b)	by the Partnership Parties, on the one hand, or the Contributing Parties, on the other hand, in writing after November 30, 2012, if the Closing has not occurred by
such date, provided that as of such date the terminating party is not in default under this Agreement; 

  

	 	(c)	by the Partnership Parties, on the one hand, or the Contributing Parties, on the other hand, in writing without prejudice to other rights and remedies that the
terminating party or its Affiliates may have (provided the terminating party and its Affiliates are not otherwise in material default or breach of this Agreement, or have not failed or refused to close without justification hereunder), if the other
party has breached or failed to perform in any respect any of its representations, warranties, covenants or agreements contained herein and such breach or failure to perform (i) would give rise to the failure of any condition specified in
ARTICLE 6, (ii) cannot be cured or has not been cured within ten (10) days following delivery of written notice from the non-defaulting party of such breach of this Agreement and (iii) has not been waived by the non-defaulting party;

  

	 	(d)	by the Partnership Parties, on the one hand, or the Contributing Parties, on the other hand, in writing, without liability, if there shall be any order, writ,
injunction or decree of any Governmental Authority binding on any of the parties, which prohibits or restrains them from consummating the transactions contemplated hereby, provided that the parties shall have used their commercially reasonable
efforts to have any such order, writ, injunction or decree lifted and the same shall not have been lifted within thirty (30) days after entry by any such Governmental Authority; 

 

	 	(e)	by the Contributing Parties if any of the conditions set forth in Section 6.2 have become incapable of fulfillment, and have not been waived in writing by
the Contributing Parties; or 

  

	 	(f)	by the Partnership Parties if any of the conditions set forth in Section 6.1 have become incapable of fulfillment, and have not been waived in writing by
the Partnership Parties. 

  
 42 

 8.2 Effect of Termination. 
 If a party terminates this Agreement as provided in Section 8.1 above, such termination shall be without liability and none of the provisions of this Agreement shall remain effective or
enforceable, except for those contained in this Section 8.2 and ARTICLE 10. Notwithstanding and in addition to the foregoing, in the event that this Agreement is terminated pursuant to Section 8.1(c) or if any party is
otherwise in breach of this Agreement, (a) such breaching party or parties shall remain liable for its or their obligations under ARTICLE 7 and/or ARTICLE 9, and (b) such termination shall not relieve such breaching party of any liability
for a willful breach of any covenant or agreement under this Agreement or be deemed a waiver of any available remedy (including specific performance, if available) for any such breach. 

ARTICLE 9 

INDEMNIFICATION UPON CLOSING 

9.1 Indemnification of the Partnership Parties. 
 Subject to the limitations set forth in this Agreement, the Contributing Parties, from and after the Closing Date, shall indemnify, defend and hold the Partnership Parties, their subsidiaries and their
respective securityholders, directors, officers, and employees, and the officers, directors and employees of the General Partner, but otherwise excluding the Contributing Parties and its Affiliates (the “Partnership Indemnified
Parties”) harmless from and against any and all Damages suffered or incurred by any Partnership Indemnified Party as a result of or arising out of (i) any breach or inaccuracy of a representation or warranty of the Contributing Parties
in this Agreement or any Contributing Parties Closing Document, (ii) any breach of any agreement or covenant on the part of the Contributing Parties made under this Agreement or any Contributing Parties Closing Document or in connection with
the transaction contemplated hereby or thereby, or (iii) any breach or violation of any Environmental Laws by the Contributed Entities that occurs prior to Closing; provided, however, that with regard to subsection (iii), the
Contributing Parties shall only be required to indemnify the Partnership Indemnified Parties for Damages attributable to the Contributed Interest. For purposes of this Section 9.1, whether the Contributing Parties have breached any of
their representations and warranties herein shall be determined without giving effect to any qualification as to “materiality” (including the word “material” or “Contributed Entity Material Adverse Effect”). 

9.2 Indemnification of the Contributing Parties. 
 Subject to the limitations set forth in this Agreement, the Partnership Parties shall indemnify, defend and hold the Contributing Parties, their Affiliates (other than any of the Partnership Indemnified
Parties) and their respective securityholders, directors, officers, and employees (the “Contributing Indemnified Parties”) harmless from and against any and all Damages suffered or incurred by the Contributing Indemnified Parties as
a result of or arising out of (i) any breach or inaccuracy of a representation or warranty of the Partnership Parties in this Agreement or any Partnership Parties Closing Document, or (ii) any breach of any agreement or covenant on the
part of the Partnership Parties made under this Agreement or any Partnership Parties Closing Document or in connection with the transaction contemplated hereby or thereby. For purposes of this Section 9.2, whether the Partnership Parties
have breached any of their representations and warranties herein shall be determined without giving effect to any qualification as to “materiality” (including the word “material” or “Partnership Material Adverse
Effect”). 

  
 43 

 9.3 Tax Indemnification. 
 With the exception of a breach or inaccuracy of the representations and warranties of the Contributing Parties contained in Section 3.10, nothing in this ARTICLE 9 shall apply to liability
with respect to Taxes, the liability with respect to which shall be as set forth in ARTICLE 7. 
 9.4 Survival. 

All the provisions of this Agreement shall survive the Closing, notwithstanding any investigation at any time made by or on behalf
of any party hereto, provided that the representations and warranties set forth in ARTICLE 3 and ARTICLE 4 and in any certificate delivered in connection herewith with respect to any of those representations and warranties shall terminate and expire
on the first day of the 18th month following the month in
which Closing occurs, except (a) the representations and warranties of the Contributing Parties set forth in Section 3.10 shall survive until 30 days after the expiration of the applicable statutes of limitations (including all
periods of extension and tolling), (b) the representations and warranties of the Contributing Parties set forth in Section 3.11 and Section 3.15 shall terminate and expire on the third anniversary of the Closing Date,
(c) the representations and warranties of the Contributing Parties set forth in Section 3.1, Section 3.2 and Section 3.4 shall survive forever and (d) the representations and warranties of the
Partnership Parties set forth in Section 4.1 and Section 4.2 shall survive forever. After a representation and warranty has terminated and expired, no indemnification shall or may be sought pursuant to this ARTICLE 9 on the
basis of that representation and warranty by any Person who would have been entitled pursuant to this ARTICLE 9 to indemnification on the basis of that representation and warranty prior to its termination and expiration, provided that in the case of
each representation and warranty that shall terminate and expire as provided in this Section 9.4, no claim presented in writing for indemnification pursuant to this ARTICLE 9 on the basis of that representation and warranty prior to its
termination and expiration shall be affected in any way by that termination and expiration. The indemnification obligations under this ARTICLE 9 or elsewhere in this Agreement shall apply regardless of whether any suit or action results solely or in
part from the active, passive or concurrent negligence or strict liability of the indemnified party. The covenants and agreements entered into pursuant to this Agreement to be performed after the Closing shall survive the Closing. 

9.5 Demands. 
 Each indemnified party
hereunder agrees that promptly upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise,
by any third party (such claims for indemnity involving third-party claims being collectively referred to herein as the “Indemnity Claim”), with respect to any matter as to which it claims to be entitled to indemnity under the
provisions of this Agreement, it will give prompt notice thereof in writing to the indemnifying party, together with a statement of such information respecting any of the foregoing as it shall have. Such notice shall include a formal demand for
indemnification under this Agreement. 

  
 44 

 If the indemnified party knowingly failed to notify the indemnifying party thereof in accordance with the
provisions of this Agreement in sufficient time to permit the indemnifying party or its counsel to defend against an Indemnity Claim and to make a timely response thereto, the indemnifying party’s indemnity obligation relating to such Indemnity
Claim shall be limited to the extent that such failure has actually prejudiced or damaged the indemnifying party with respect to that Indemnity Claim. 
 9.6 Right to Contest and Defend. 
 The indemnifying party shall be entitled, at its cost
and expense, to contest and defend by all appropriate legal proceedings any Indemnity Claim for which it is called upon to indemnify the indemnified party under the provisions of this Agreement; provided, that notice of the intention to so
contest shall be delivered by the indemnifying party to the indemnified party within twenty (20) days from the date of receipt by the indemnifying party of notice by the indemnified party of the assertion of the Indemnity Claim. Any such
contest may be conducted in the name and on behalf of the indemnifying party or the indemnified party as may be appropriate. Such contest shall be conducted by reputable counsel employed by the indemnifying party and not reasonably objected to by
the indemnified party, but the indemnified party shall have the right but not the obligation to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense. 

The indemnifying party shall have full authority to determine all action to be taken with respect thereto; provided, however, that the
indemnifying party will not have the authority to subject the indemnified party to any obligation whatsoever, other than the performance of purely ministerial tasks or obligations not involving material expense or injunctive relief. If the
indemnifying party does not elect to contest any such Indemnity Claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party assumes the defense of an Indemnity Claim,
the indemnified party shall agree to any settlement, compromise or discharge of an Indemnity Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection
with such Indemnity Claim, which releases the indemnified party completely in connection with such Indemnity Claim and which would not otherwise adversely affect the indemnified party as determined by the indemnified party in its sole discretion.

 Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Indemnity Claim (and shall be liable
for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Indemnity Claim) if the Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the
indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Indemnity Claim can
be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages. 

  
 45 

 9.7 Cooperation. 
 If requested by the indemnifying party, the indemnified party agrees to cooperate with the indemnifying party and its counsel in contesting any Indemnity Claim that the indemnifying party elects to
contest or, if appropriate, in making any counterclaim against the person asserting the Indemnity Claim, or any cross-complaint against any person, and the indemnifying party will reimburse the indemnified party for any expenses incurred by it in so
cooperating. At no cost or expense to the indemnified party, the indemnifying party shall cooperate with the indemnified party and its counsel in contesting any Indemnity Claim. 
 9.8 Right to Participate. 
 The indemnified party agrees to afford the indemnifying party
and its counsel the opportunity to be present at, and to participate in, conferences with all Persons, including Governmental Authorities, asserting any Indemnity Claim against the indemnified party or conferences with representatives of or counsel
for such Persons. 
 9.9 Payment of Damages. 
 The indemnification required hereunder in respect of Indemnity Claims shall be made by periodic payments of the amount of Damages in connection therewith, within ten (10) days as and when reasonably
specific bills are received by, or Damages are incurred and reasonable evidence thereof is delivered to, the indemnifying party. In calculating any amount to be paid by an indemnifying party by reason of the provisions of this Agreement, the amount
shall be reduced by all insurance proceeds and any indemnification reimbursement proceeds received from third parties credited to or received by the indemnified party related to the Damages. 
 9.10 Limitations on Indemnification. 
  

	 	(a)	To the extent that the Partnership Indemnified Parties would otherwise be entitled to indemnification for Damages pursuant to Section 9.1, the Contributing
Parties shall be liable only if (i) the Damages with respect to a claim exceed $825,000 (the “Minimum Claim Amount”) and (ii) the Damages for all claims that exceed the Minimum Claim Amount exceed, in the aggregate,
$24,000,000 (the “Deductible Amount”), and then the Contributing Parties shall be liable only for Damages to the extent of any excess over the Deductible Amount. In no event shall the Contributing Parties’ aggregate liability
to the Partnership Indemnified Parties under Section 9.1 exceed $280,000,000 (the “Ceiling Amount”). Notwithstanding the foregoing, (i) the Deductible Amount shall not apply to breaches or inaccuracies of
representations and warranties contained in Section 3.1, Section 3.2, Section 3.4, Section 3.21 and Section 3.22 and (ii) the Ceiling Amount shall not apply to breaches or inaccuracies
of representations and warranties contained in Section 3.4; provided, that the Contributing Parties’ aggregate liability for a breach or inaccuracy of such Section 3.4 shall not exceed an amount equal to the
Aggregate Consideration minus the amount of all other Damages payable by the Contributing Parties hereunder. 

  
 46 

	 	(b)	To the extent the Contributing Indemnified Parties would otherwise be entitled to indemnification for Damages pursuant to Section 9.2, the Partnership
Parties shall be liable only if (i) the Damages with respect to a claim exceed the Minimum Claim Amount and (ii) the Damages for all claims that exceed the Minimum Claim Amount exceed, in the aggregate, the Deductible Amount, and then the
Partnership Parties shall be liable only for Damages to the extent of any excess over the Deductible Amount. In no event shall the Partnership Parties’ aggregate liability to the Contributing Indemnified Parties under Section 9.2
exceed the Ceiling Amount. Notwithstanding the foregoing, the Deductible Amount shall not apply to breaches or inaccuracies of representations and warranties contained in Section 4.1, Section 4.2 and Section 4.4.

  

	 	(c)	Additionally, neither the Partnership Parties, on the one hand, nor the Contributing Parties, on the other hand, will be liable as an indemnitor under this Agreement
for any consequential, incidental, special, indirect or exemplary damages suffered or incurred by the indemnified party or parties except to the extent resulting pursuant to Indemnity Claims. 

9.11 Sole Remedy. 
 Should the Closing
occur, no party shall have liability under this Agreement, any of the Closing Documents or the transactions contemplated hereby or thereby except as is provided in ARTICLE 7 or this ARTICLE 9 (other than claims or causes of action arising from
intentional fraud). 
 ARTICLE 10 
 MISCELLANEOUS 
 10.1 Expenses. 
 Except as otherwise provided herein and regardless of whether the transactions contemplated hereby are consummated, each party shall pay its own expenses incident to this Agreement and all action taken in
preparation for carrying this Agreement into effect.

10.5 Entire Agreement; Amendments and Waivers. 
  

	 	(a)	This Agreement and the Closing Documents constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements

 10.6 Conflicting Provisions. 
 This Agreement and the Closing Documents, read as a whole, set forth the parties’ rights, responsibilities and liabilities with respect to the transactions contemplated by this Agreement. In this

 10.8 Severability. 
 If any provision of the Agreement is rendered or declared illegal or unenforceable by reason of any existing or subsequently enacted legislation or by decree of a court of last resort, the Partnership
Parties and the Contributing Parties shall promptly meet and negotiate substitute provisions for those rendered or declared illegal or unenforceable, but all of the remaining provisions of this Agreement shall remain in full force and effect.

 It is
expressly agreed by the parties that neither this Agreement nor any of the Closing Documents shall be construed against any party, and no consideration shall be given or presumption made, on the basis of who drafted this Agreement, any Closing
Document or any provision hereof or thereof or who supplied the form of this Agreement or any of the Closing Documents. Each party agrees that this Agreement has been purposefully drawn and correctly reflects its understanding of the transactions

document.

ARTICLE I 

DEFINITIONS 
 1.1 Definitions. The following capitalized terms have the meanings given below.
