2.1 Manner of Filing

preparation and filing of a Combined Return, including, without limitation, (i) making elections and adopting accounting methods, (ii) filing all extensions of time, including

and exclusive responsibility for the preparation and filing of, and shall prepare and file or cause to be prepared and filed, all Tax Returns of the Partnership Group Members that are not Combined Returns. 

(c) DBE shall have sole discretion to include, or cause to be included, in a Combined Return for any Tax any member of the
Partnership Group for which inclusion in such Combined Return is elective; provided, however, that the Partnership Group Combined Tax Liability for any period shall not exceed the aggregate of (x) each such elective Partnership Group
Member’s liability for such Tax for such period, computed as if such Partnership Group Member were not included in such Combined Return and (y) the Partnership Group Combined Tax Liability calculated for the Partnership Group Members for

 2.2 Franchise Tax Taxable Period. References to “taxable period” for any franchise or
other doing business Tax shall mean 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

 ARTICLE III 

Allocation of Taxes 
 3.1
Liability of the Partnership Group for Combined Taxes. For each Tax for each taxable period that includes or begins on or after the Effective Date and for which a Combined Return is filed, the Partnership Group Members included in such
Combined Return shall be liable to DBE for an amount equal to the Partnership Group Combined Tax Liability in respect of such Tax. 
 3.2
Partnership Group Combined Tax Liability. With respect to each Tax for each taxable period that includes or begins on or after the Effective Date and for which a member of the Partnership Group is included in a Combined Return, the
Partnership Group Combined Tax Liability for such Tax for such taxable period shall be the Tax for such taxable period as determined on a Partnership Group Pro Forma Combined Return prepared: 

(a) by including only the Tax Items of the members of the Partnership Group that are included in the Combined Return and computing the
liability of the Partnership Group Members for such Tax as if such Partnership Group Members were included in a separate combined, consolidated or unitary return that includes only the Partnership Group Members; 

(b) except as provided in Section 3.2(e) hereof, using all elections, accounting methods and conventions used on the Combined Return for
such period; 

  
 5 

 (c) applying the Tax rate in effect for the Combined Return of the Combined Group for such
taxable period; 
 (d) assuming that the Partnership Group elects not to carry back any net operating losses; and 

(e) assuming that the Partnership Group’s utilization of any Tax Attribute carryforward or carryback is limited to the Tax Attributes of
the Partnership Group that would be available if the Partnership Group Combined Tax Liability for each taxable period ending after the Effective Date were determined in accordance with this Section 3.2. 

3.3 Preparation and Delivery of Pro Forma Tax Returns. Not later than 90 days following the date on which a Combined Return is
filed with the appropriate Tax Authority, DBE shall prepare and deliver to the Partnership the related Partnership Group Pro Forma Combined Return calculating the Partnership Group Combined Tax Liability attributable to the period covered by such
filed Combined Return. 
 3.4 Payment of Tax. DBE shall timely pay (or shall cause to be timely paid) any Tax reflected on a
Combined Return and hold the Partnership harmless for all liability for such Tax. In the event DBE is required to make an estimated payment or deposit of any Tax of any Combined Group which includes any member of the Partnership Group, DBE shall
calculate the portion, if any, of such estimated payment or deposit attributable to the Partnership Group using a methodology similar to that described in Section 3.2 (the “Partnership Group Deposit”) and shall present
such calculation to the Partnership. Within 5 days thereafter, the Partnership shall pay the Partnership Group Deposit to DBE. Within 30 days after delivery by DBE of a Partnership Group Pro Forma Combined Return to the Partnership calculating the
Partnership Group Combined Tax Liability with respect to a Combined Return, the Partnership shall pay to DBE such Partnership Group Combined Tax Liability less the amount of any Partnership Group Deposit relating to the same Combined Return. 

3.5 Subsequent Changes in Treatment of Tax Items. With respect to any Combined Return for any taxable period beginning on or
after the Effective Date, in the event of a change in the treatment of any Tax Item of any member of a Combined Group as a result of a Final Determination, within 30 days following such Final Determination (i) DBE shall calculate the change, if
any, to the Partnership Group Combined Tax Liability resulting from such change, (ii) DBE shall pay any decrease in the Partnership Group Combined Tax Liability to the Partnership and (iii) the Partnership shall pay any increase in the
Partnership Group Combined Tax Liability to DBE. 
 ARTICLE IV

handling, settling or contesting any Tax Controversy involving a Tax Return for which it has filing responsibility under this Agreement as well as all Tax Returns for all taxable periods ending before the Effective Date. The Partnership shall have
full responsibility and discretion in handling, settling or contesting any Tax Controversy 

  
 6 

 
involving a Tax Return for which it has filing responsibility under this Agreement. Except as otherwise provided in this Article IV, any costs incurred in handling, settling or contesting any Tax
Controversy shall be borne by the Party having full responsibility and discretion thereof. 
 4.2 Cooperation and Exchange of
Information. 
 (a) Each Party shall cooperate fully at such time and to the extent reasonably requested by any other Party

helpful in connection with the foregoing; (iii) the execution of any document that may be necessary or reasonably helpful in connection with the filing of a Tax Return by DBE, the Partnership or of their respective subsidiaries, or in
connection with any audit, dispute, proceeding, suit or action and (iv) such Party’s commercially reasonable efforts to obtain any documentation from a governmental authority or a third party that may be necessary or reasonably helpful in
connection with any of the foregoing. 
 (b) Each Party shall make its employees and facilities available on a reasonable and mutually
convenient basis in connection with any of the foregoing matters. 
 (c) If any Party fails to provide any information requested pursuant to
Section 4.2 hereof within a reasonable period, as determined in good faith by the Party requesting the information, then the requesting Party shall have the right to engage a public accounting firm to gather such information, provided that 30
days’ prior written notice is given to the unresponsive Party. If the unresponsive Party fails to provide the requested information within 30 days of receipt of such notice, then such unresponsive Party shall permit the requesting Party’s
public accounting firm full access to all appropriate records or other information as reasonably necessary to comply with this Section 4.2 and shall reimburse the requesting Party or pay directly all costs connected with the requesting
Party’s engagement of the public accounting firm.

(iv) the final resolution of any claim made under this Agreement for which such information is relevant. 
 5.6 Continuing
Covenants. Each Party agrees (i) not to take any action reasonably expected to result in a new or changed Tax Item that is detrimental to any other Party and (ii) to take any action reasonably requested by any other Party that
would reasonably be expected to result in a new or changed Tax Item that produces a benefit or avoids a detriment to such other Party; provided that such action does not result in any additional cost not fully compensated for by the requesting
Party. The Parties hereby acknowledge that the preceding sentence is not intended to limit, and therefore shall not apply to, the rights of the Parties with respect to matters otherwise covered by this Agreement.

6.4 Further Assurances. Subject to the provisions hereof, the Parties hereto shall make, execute, acknowledge and deliver such
other instruments and documents, and take all such other actions, as may be reasonably required in order to effectuate the purposes of this Agreement and to consummate the transactions contemplated hereby. Subject to the provisions hereof, each of

in order to be able to comply with the provisions of this sentence.

specifically provided, nothing in this Agreement expressed or implied is intended to confer any right or benefit upon any person, firm or corporation other than the Parties and their respective successors and permitted assigns. 

6.6 Setoff. Except as provided by Section 2.1(c) of this Agreement, all payments to be made under this Agreement shall be
made without setoff, counterclaim or withholding, all of which are expressly waived. 
 6.7 Change of Law. If, due to any
change in applicable law or regulations or the interpretation thereof by any court of law or other governing body having jurisdiction subsequent to the date of this Agreement, performance of any provision of this Agreement or any transaction
contemplated hereby shall become impracticable or impossible, the Parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such provision.

 6.9 Amendments; No Waivers. 

(a) Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case
of an amendment, by DBE and the Partnership, or in the case of a waiver, by the Party against whom the waiver is to be effective. 
 (b) No
failure or delay by any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right,
power or privilege. 

  
 10 

 6.10 Governing Law and Interpretation. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware applicable to agreements made and to be performed in the State of Delaware. 

6.11 Resolution of Certain Disputes. Any disagreement between the Parties with respect to any matter that is the subject of this
Agreement, including, without limitation, any disagreement with respect to any calculation or other determinations by DBE hereunder, which is not resolved by mutual agreement of the Parties, shall be resolved by a nationally recognized independent
accounting firm chosen by and mutually acceptable to the Parties hereto (an “Accounting Referee”). Such Accounting Referee shall be chosen by the Parties within fifteen (15) business days from the date on which one Party
serves written notice on another Party requesting the appointment of an Accounting Referee, provided that such notice specifically describes the calculations to be considered and resolved by the Accounting Referee. In the event the Parties cannot
agree on the selection of an Accounting Referee, then the Accounting Referee shall be any office or branch of the public accounting firm of PricewaterhouseCoopers LLP. The Accounting Referee shall resolve any such disagreements as specified in the
notice within 30 days of appointment; provided, however, that no Party shall be required to deliver any document or take any other action pursuant to this Section 6.11 if it determines that such action would result in the waiver of any legal
privilege or any detriment to its business. Any resolution of an issue submitted to the Accounting Referee shall be final and binding on the Parties hereto without further recourse. The Parties shall share the costs and fees of the Accounting
Referee equally. 
 6.12 Confidentiality. Except to the extent required to protect a Party’s interests in a Tax
Controversy, each Party shall hold and shall cause its consultants and advisors to hold in strict confidence, unless compelled to disclose by judicial or administrative process or, in the opinion of its counsel, by other requirements of law, all
information (other than any such information relating solely to the business or affairs of such Party) concerning another Party or its representatives pursuant to this Agreement (except to the extent that such information can be shown to have been
(i) previously known by the Party to which it was furnished, (ii) in the public domain through no fault of such Party or (iii) later lawfully acquired from other sources by the Party to which it was furnished), and each Party shall
not release or disclose such information to any other person, except its auditors, attorneys, financial advisors, bankers and other consultants and advisors who shall be advised of the provisions of this Agreement. Each Party shall be deemed to have
satisfied its obligation to hold confidential information concerning or supplied by another Party if it exercises the same care as it takes to preserve confidentiality for its own similar information. 

6.13 Costs, Expenses and Attorneys’ Fees. Except as expressly set forth in this Agreement, each Party shall bear its own
costs and expenses incurred pursuant to this Agreement. In the event a Party to this Agreement brings an action or proceeding for the breach or enforcement of this Agreement, the prevailing party in such action, proceeding or appeal, whether or not
such action, proceeding or appeal proceeds to final judgment, shall be entitled to recover as an element of its costs, and not as damages, such reasonable attorneys’ fees as may be 

  
 11 

 
awarded in the action, proceeding or appeal in addition to whatever other relief the prevailing party may be entitled. For purposes of this Section 6.13, the “prevailing party”
shall be the Party who is entitled to recover its costs; a Party not entitled to recover its costs shall not recover attorneys’ fees. No sum for attorneys’ fees shall be counted in calculating the amount of the judgment for purposes of
determining whether a Party is entitled to recover its costs or attorneys’ fees. 
 6.14 Counterparts. This Agreement may
be executed in one or more counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument. 

6.15 Severability. The Parties hereby agree that, if any provision of this Agreement should be adjudicated to be invalid or
unenforceable, such provision shall be deemed deleted herefrom with respect, and only with respect, to the operation of such provision in the particular jurisdiction in which such adjudication was made, and only to the extent of the invalidity, and
any such invalidity or unenforceability in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. All other remaining provisions of this Agreement shall remain in full force and effect for
the particular jurisdiction and all other jurisdictions. 
 6.16 Entire Agreement. 

(a) This Agreement contains the entire agreement between the Parties with respect to the subject matter hereof and supersedes all other
agreements, whether or not written, in respect of any Tax between the DBE Group and the Partnership Group. 
 (b) In the event of any
conflict or inconsistency between the provisions of this Agreement and the provisions of any other agreement between the DBE Group and the Partnership Group, the provisions of this Agreement shall take precedence and to such extent shall be deemed
to supersede such conflicting provisions under the other agreement. 
 6.17 Assignment. This Agreement is being entered into
by DBE and the Partnership on behalf of themselves and each member of the DBE Group and the Partnership Group. This Agreement shall constitute a direct obligation of each such member and shall be deemed to have been readopted and affirmed on behalf
of any entity that becomes a member of the DBE Group or the Partnership Group in the future. Each of DBE and the Partnership hereby guarantee the performance of all actions, agreements and obligations provided for under this Agreement of each member
of the DBE Group and the Partnership Group, respectively. Each of DBE and the Partnership shall, upon the written request of the other, cause any of their respective group members to formally execute this Agreement. This Agreement shall be binding
upon, and shall inure to the benefit of, the successors, assigns and persons controlling any of the entities bound hereby for so long as such successors, assigns or controlling persons are members of the DBE Group or the Partnership Group or their
successors and assigns. 
 6.18 Fair Meaning. This Agreement shall be construed in accordance with its fair meaning and shall
not be construed strictly against the drafter.

 6.19 Titles and Headings. Titles and headings to sections herein are inserted for
