Each DM Public Unit, upon being converted into the right to receive the Merger Consideration pursuant to Section 2.1(c)(i) or Section 2.1(c)(ii), as applicable, shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each Holder of such DM Public Units immediately prior to the Effective Time shall thereafter cease to be a limited partner of DM or have any rights with respect to such DM Public Units, (A) except the right to receive the Merger Consideration, and (B) the right to receive any dividends, distributions and

12

Fractional Share Payments to which former Holders of DM Public Units become entitled, all in accordance with this Article II upon the Surrender of uncertificated DM Public Units represented by book-entry form (“Book-Entry DM Public Units”), and receipt of such other documents in accordance with Section 2.2.

(iv) Treatment of DM-Owned Units, Parent-Owned Partnership Interests and Non-Converting Series A Holders. Any DM Units that are owned immediately prior to the Effective Time by DM shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange for such canceled DM Units. The (A) DM General Partner Interest, (B) DM Incentive Distribution Rights, (C) DM Units that are not DM Public Units and are not cancelled pursuant to the preceding sentence, and (D) DM Public Series A Preferred Units held by Non-Converting Series A Holders shall, in each case, remain outstanding as partnership interests in the Surviving Entity, unaffected by the Merger.

(v) Equity of Merger Sub. The outstanding limited liability company interest in Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into an aggregate number of DM Common Units equal to the number of DM Public Units that are converted into the right to receive the Merger Consideration pursuant to Section 2.1(c)(i) and Section 2.1(c)(ii), and the holder of such DM Common Units shall be admitted as a limited partner of DM. At the Effective Time, the books and records of DM shall be revised to reflect the cancellation and retirement of all DM Public Units and the conversion of the limited liability company interest in Merger Sub to DM Common Units, the admission of the sole member of Merger Sub as a limited partner of DM and the existence of DM (as the Surviving Entity) shall continue without dissolution.

(d) Other Effects of the Merger. The Merger shall be conducted in accordance with and shall have the effects set forth in this Agreement and the applicable provisions of DRULPA and DLLCA. At the Effective Time, (i) the certificate of limited partnership of DM shall continue as the certificate of limited partnership of the Surviving Entity, and (ii) the DM Partnership Agreement shall remain unchanged and shall continue as the agreement of limited partnership of the Surviving Entity.

(e) No Fractional Shares. Notwithstanding any other provision of this Agreement, (i) no certificates or scrip representing fractional shares of Parent Common Stock shall be issued in the Merger and (ii) each registered Holder of DM Public Units exchanged pursuant to the Merger who would otherwise have been entitled to receive a fractional share of Parent Common Stock (after taking into account all DM Public Units held by such Holder immediately prior to the Effective Time) shall receive from Parent, in lieu of such fractional share, an amount (a “Fractional Share Payment”) in cash (payable in dollars, without interest) equal to the product of (A) such fraction, multiplied by (B) the average of the closing price of Parent Common Stock as reported on the NYSE Composite Transactions Tape (as reported by Bloomberg Financial Markets or such other source as the parties shall agree in writing) over the five trading day period ending on the third trading day immediately preceding the Effective Time. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares of Parent Common Stock was not separately bargained-for consideration but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience to Parent that would otherwise be caused by the issuance of fractional shares of Parent Common Stock.

13

(f) Certain Adjustments. If between the Execution Date and the Effective Time, whether or not permitted pursuant to the terms of this Agreement, the number of outstanding DM Common Units or shares of Parent Common Stock shall be changed into a different number of units, shares or other securities (including any different class or series of securities) by reason of any dividend or distribution payable in partnership interests, voting securities, equity interests or Rights, subdivision, reclassification, split, split-up, combination, merger, consolidation, reorganization, exchange or other similar transaction, or any such transaction shall be authorized, declared or agreed upon with a record date at or prior to the Effective Time, then the Merger Consideration, and any other similarly dependent items shall be appropriately adjusted to reflect fully the effect of such transaction and to provide to DM, Merger Sub and the Holders of DM Restricted Unit Awards and DM Public Units the same economic effect as contemplated by this Agreement prior to such event, and thereafter, all references in this Agreement to the Merger Consideration, and any other similarly dependent items shall be references to the Merger Consideration, and any other similarly dependent items, as so adjusted; provided, however, that nothing in this Section 2.1(f) shall be deemed to permit or authorize any party hereto to effect any such dividend or distribution payable in equity securities or Rights, subdivision, reclassification, split, split-up, combination, merger, consolidation, reorganization, exchange or other similar transaction, or the authorization, declaration or agreement to do such transaction that it is not otherwise authorized or permitted to be undertaken pursuant to this Agreement; provided, further, for the avoidance of doubt, that no adjustment to the Merger Consideration shall be made relating to the merger pursuant to the SCANA Merger Agreement.

SECTION 2.2 Exchange of DM Public Units.

(a) Exchange Agent. Prior to the Effective Time, Parent shall appoint Equiniti Trust Company to act as exchange agent (the “Exchange Agent”) for the payment of the Merger Consideration and any dividends or distributions payable pursuant to Section 2.2(c) and any Fractional Share Payment. At or prior to the Effective Time, Parent shall (A) deposit with the Exchange Agent, for the benefit of the Holders of DM Public Units, an amount of cash sufficient to effect the delivery of the estimated aggregate Fractional Share Payment and, if the Effective Time occurs on or after the record date for the Parent First Quarter Dividend, an amount of cash sufficient to effect the payment of the Parent First Quarter Dividend to Holders of DM Public Units in accordance with Section 2.1(c) (the “Exchange Fund”), (B) reserve with the Exchange Agent the shares of Parent Common Stock to be issued pursuant to Section 2.1(c)(i) and Section 2.1(c)(ii), and (C) authorize the Exchange Agent to exchange shares of Parent Common Stock in accordance with this Section 2.2. In addition, Parent shall deposit with the transfer agent an amount of cash sufficient to effect the delivery of any declared but unpaid DM distributions payable pursuant to Section 2.2(d) in the ordinary course. Parent shall deposit with the Exchange Agent any additional cash or other consideration as applicable in excess of the Exchange Fund as and when necessary to pay any dividends or distributions payable pursuant to Section 2.2(c), any Fractional Share Payment and other amounts required to be paid under this Agreement. Parent shall pay all costs and fees of the Exchange Agent and all expenses associated with the exchange process. Any shares of Parent Common Stock, and any remaining amount of the Exchange Fund or other funds deposited shall be returned to Parent after the earlier to occur of (x) payment in full of all amounts due to the Holders of DM Public Units and (y) the expiration of the period specified in Section 2.2(e).

14

(b) Exchange Procedures. Each Holder of record of one or more Book-Entry DM Public Units shall upon receipt by the Exchange Agent of an “agent’s message” in customary form (it being understood that the Holders of Book-Entry DM Public Units shall be deemed to have Surrendered such DM Public Units upon receipt by the Exchange Agent of such “agent’s message” or such other evidence, if any, as the Exchange Agent may reasonably request) be entitled to receive, and Parent shall cause the Exchange Agent to pay and deliver as promptly as practicable after the Effective Time, (A) a cash amount in immediately available funds equal to (1) any dividends and other distributions such Holder has the right to receive pursuant to Section 2.2(c) plus (2) any cash in lieu of any Fractional Share Payment such Holder has the right to receive pursuant to Section 2.1(e) plus (3) if the Effective Time occurs after the record date for the Parent First Quarter Dividend, an amount of cash sufficient to effect payment of the Parent First Quarter Dividend to Holders of DM Common Units in accordance with Section 2.1(c), and (B) the number of whole shares of Parent Common Stock, in uncertificated book-entry form, such Holder has the right to receive pursuant to Section 2.1(c).

(c) Dividends and Distributions with Respect to Unexchanged DM Public Units. No dividends or other distributions with respect to shares of Parent Common Stock issued in the Merger with a record date after the Effective Time shall be paid to the Holder of any Book-Entry DM Public Units not Surrendered with respect to such shares of Parent Common Stock issuable in respect thereof until the Surrender of such Book-Entry DM Public Units in accordance with this Section 2.2. Subject to the effect of applicable Laws, Parent shall pay, or cause the Exchange Agent to pay, to each Holder of Book-Entry DM Public Units, without interest, (i) at the time of Surrender of such Book-Entry DM Public Units, the amount of dividends or other distributions previously paid with respect to the whole shares of Parent Common Stock issuable with respect to such Book-Entry DM Public Units that have a record date after the Effective Time and a payment date on or prior to the time of Surrender and (ii) at the appropriate payment date, the amount of dividends and distributions payable with respect to such whole shares of Parent Common Stock with a record date after the Effective Time and prior to such Surrender and a payment date subsequent to such Surrender.

(d) No Further Ownership Rights in DM Public Units. All Merger Consideration issued upon the Surrender for exchange of Book-Entry DM Public Units in accordance with the terms of this Article II (including any Fractional Share Payment) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the DM Public Units heretofore represented by such Book-Entry DM Public Units, subject, however, to Parent’s obligation, notwithstanding the conversion of DM Public Units pursuant to this Agreement, with respect to DM Public Units outstanding immediately prior to the Effective Time, to pay (or cause DM to pay) to the Holder of DM Public Units as of the applicable record date any dividends and distributions with a record date at or prior to the Effective Time that may have been declared or made by DM or the DM General Partner with respect to such DM Common Units in accordance with the terms of the DM Partnership Agreement on or prior to the Effective Time and that remain unpaid at the Effective Time.

15

(e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the Holders of the Book-Entry DM Public Units for twelve months after the Closing Date shall be delivered to Parent, upon demand, and any Holders of the Book-Entry DM Public Units who have not theretofore complied with this Section 2.2 shall thereafter look only to Parent and only as general creditors thereof for payment of their claim for the Merger Consideration, any Fractional Share Payment and any dividends and distributions with respect to DM Common Units or shares of Parent Common Stock to which such Holders may be entitled.

(f) No Liability. To the extent permitted by applicable Law, none of Parent, Merger Sub, DM, DM General Partner or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration, distribution or Fractional Share Payment properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Book-Entry DM Public Units shall not have been Surrendered immediately prior to such date on which any Merger Consideration, any Fractional Share Payment or any dividends and distributions with respect to DM Common Units or shares of Parent Common Stock in respect of such Book-Entry DM Public Units would escheat to or become the property of any Governmental Entity, any such units, cash or distributions in respect of such Book-Entry DM Public Units shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(g) Withholding Rights. Parent, Merger Sub and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, without duplication, such amounts, which may include shares of Parent Common Stock, as Parent, Merger Sub or the Exchange Agent reasonably deems to be required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Entity by Parent, Merger Sub or the Exchange Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made by Parent, Merger Sub or the Exchange Agent, as the case may be.

(h) No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement.

SECTION 2.3 Treatment of DM Restricted Unit Awards.

(a) At the Effective Time, each DM Restricted Unit Award that is not vested and does not vest in accordance with its terms (as set forth in an applicable award agreement) as a result of the transactions contemplated by this Agreement and that is outstanding as of immediately prior to the Effective Time, shall cease to represent an award with respect to DM Common Units and shall be converted into an award with respect to shares of Parent Common Stock (a “Parent Award”), subject to the same vesting and forfeiture provisions as were applicable under such DM Restricted Unit Award immediately prior to the Effective Time, with the number of shares of Parent Common Stock subject to each such Parent Award to be equal to the number of DM Common Units subject to each such DM Restricted Unit Award immediately prior to the Effective Time multiplied by the Exchange Ratio (such product, rounded to the nearest whole share), with any corresponding accrued but unpaid DERs (as defined in the ▇▇ ▇▇▇▇-Term Incentive Plan) with respect to any DM Restricted Unit Awards to be assumed, remain outstanding and continue to represent an obligation with respect to the applicable Parent Award.

16

(b) Prior to the Effective Time, DM and DM General Partner shall take all action necessary to effectuate the provisions of this Section 2.3. DM and DM General Partner shall ensure that, as of immediately following the Effective Time, no holder of a DM Restricted Unit Award or participant in the ▇▇ ▇▇▇▇-Term Incentive Plan shall have any rights thereunder to acquire, or other rights in respect of, the equity of DM, the Surviving Entity or any of the DM Subsidiaries.

(c) Parent shall reserve for issuance a number of shares of Parent Common Stock at least equal to the number of shares of Parent Common Stock that will be subject to the Parent Awards as a result of the actions contemplated by this Section 2.3. As soon as practicable following the Effective Time, Parent shall, to the extent legally required, file a registration statement on Form S-8 (or any successor form, or if Form S-8 is not available, other appropriate forms, including Form S-3) with respect to the shares of Parent Common Stock subject to such Parent Awards and shall use its reasonable best efforts to maintain the effectiveness of any such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Parent Awards remain outstanding and the offering with respect thereto is required to be registered.

All of such DM Common Units, DM Series A Preferred Units, and DM Incentive Distribution Rights and the limited partner interests represented thereby have been duly authorized and validly issued in accordance with the DM Partnership Agreement, and are fully paid (to the extent required under the DM Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the DRULPA and the DM Partnership Agreement). The DM General Partner is the sole owner of the DM General Partner Interest and the DM General Partner Interest has been duly authorized and validly issued in accordance with the DM Partnership Agreement. As of the Execution Date, 3,000,000 DM Common Units were reserved for issuance under the ▇▇ ▇▇▇▇-Term Incentive Plan, of which 10,424 DM Common Units were subject to outstanding restricted unit awards (the “DM Restricted Unit Awards”) and no DM Common Units were subject to outstanding options, unit appreciation rights, phantom units, or equity awards of

19

any other kind. All DM Common Units reserved for issuance under the ▇▇ ▇▇▇▇-Term Incentive Plan, when issued in accordance with the respective terms thereof, are or will be duly authorized, validly issued, fully paid and non-assessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the DRULPA and the DM Partnership Agreement).

Except as set forth in the DM Partnership Agreement as in effect on the Execution Date, there are no outstanding obligations of DM or any DM Group Entity to repurchase, redeem or otherwise acquire any DM Units or other partnership interests, voting securities or equity interests or any Rights of DM or any DM Group Entity. There are no outstanding bonds, debentures, notes or other indebtedness, the holders of which have the right to vote (or which are convertible or exchangeable into or exercisable for securities having the right to vote) with the limited partners of DM on any matter.

(b) As of the Execution Date, all of the outstanding shares of capital stock or other equity or voting interests of each DM Subsidiary owned directly or indirectly by the DM Parties (i) are owned, beneficially and of record free and clear of all Liens and (ii) have been duly authorized and are validly issued, fully paid (with respect to DM Subsidiaries that are limited liability companies or limited partnerships, to the extent required under the limited liability company agreement or limited partnership agreement of the applicable DM Subsidiary) and, except for any general partner interest in a DM Subsidiary, nonassessable (with respect to DM Subsidiaries that are limited liability companies or limited partnerships, except as such nonassessability may be affected by Sections 18-607 and 18-804 of the DLLCA or by Sections 17-303, 17-607 and 17-804 of the DRULPA and the Governing Documents of the applicable entity).

SECTION 3.5 SEC Documents; Internal Controls.

(a) Since January 1, 2017, all reports, including but not limited to the Annual Reports on Form 10-K, the Quarterly Reports on Form 10-Q and the Current Reports on Form 8-K (whether filed on a voluntary basis or otherwise), forms, schedules, certifications, prospectuses, registration statements and other documents required to be filed or furnished by DM or any DM Subsidiary with or to the SEC (the “DM SEC Reports”) have been filed or furnished. For a period of at least twelve calendar months immediately prior to the Execution Date, all DM SEC Reports have been filed in a timely manner. The DM SEC Reports shall not include any reports required to be filed or furnished by any entity prior to such entity becoming a DM Subsidiary. Each of the DM SEC Reports (i) complied in all material respects with the requirements of applicable Law (including the Exchange Act, the Securities Act and the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002, as amended, and the rules and regulations promulgated thereunder (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”)), and (ii) as of its effective date (in the case of DM SEC Reports that are registration statements filed pursuant to the requirements of the Securities Act) and as of its filing date did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except for any statements (x) in any DM SEC Report that may have been modified by an amendment to such report or a subsequent report filed with the SEC prior to the Execution Date or (y) with respect to information supplied in writing by or on behalf of Parent, as to which DM makes no representation or warranty.

20

(b) Except as set forth on Section 3.5(b) of the DM Disclosure Letter, no DM Subsidiary is required to file reports, forms or other documents with the SEC pursuant to the Exchange Act. There are no outstanding comments from, or unresolved issues raised by, the staff of the SEC with respect to the DM SEC Reports. No enforcement action has been initiated against DM relating to disclosures contained or omitted from any DM SEC Report.

(c) DM makes and keeps books, records, and accounts and has devised and maintains a system of internal controls, in each case, as required pursuant to Section 13(b)(2) under the Exchange Act. DM has established and maintains disclosure controls and procedures and internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act and the applicable listing standards of the NYSE. Such disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by DM in the reports that it files under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to its management as appropriate to allow timely decisions regarding required disclosure. DM General Partner’s principal executive officer and its principal financial officer have disclosed, based on their most recent evaluation, to DM’s auditors and the audit committee of the DM Board (x) all significant deficiencies in the designation or operation of internal controls which could adversely affect DM’s ability to record, process, summarize and report financial data and have identified for DM’s auditors any material weakness in internal controls and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in DM’s internal controls.

(d) Since January 1, 2017, the principal executive officer and principal financial officer of the DM General Partner have made all certifications (without qualification or exceptions to the matters certified, except as to Knowledge) required by the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, and the statements contained in any such certifications are complete and correct, and none of such entities or its officers have received notice from any Governmental Entity questioning or challenging the accuracy, completeness, form or manner of filing or submission of such certification. As of the Execution Date, and except as disclosed in a DM SEC Report filed with the SEC prior to the Execution Date, none of such entities has any Knowledge of any material weaknesses in the design or operation of such internal controls over financial reporting.

SECTION 3.6 Financial Statements; Undisclosed Liabilities.

(a) The consolidated financial statements of DM included in the DM SEC Documents (the “DM Financial Statements”) as of their respective dates (if amended, as of the date of the last such amendment) comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared in accordance with GAAP applied on a consistent basis throughout the periods covered thereby (except as may be indicated in the notes thereto) and present fairly in all material respects the consolidated financial position of DM and its consolidated Subsidiaries as of such dates and the

21

consolidated results of operations and cash flows of DM for such periods, except as otherwise noted therein. Except as set forth in the DM Financial Statements, there are no off-balance sheet arrangements that would, individually or in the aggregate, have a DM Material Adverse Effect. DM has not had any disagreement with its independent public accounting firm that required disclosure in the DM SEC Reports.

(b) There are no liabilities or obligations of DM, DM General Partner or the DM Subsidiaries (whether known or unknown and whether accrued, absolute, contingent or otherwise), other than (i) liabilities or obligations reflected or reserved against in the DM Financial Statements, (ii) current liabilities incurred in the ordinary course of business since December 31, 2017, (iii) liabilities and obligations incurred under or in accordance with this Agreement or in connection with the transactions contemplated by this Agreement, and (iv) liabilities or obligations (whether known or unknown and whether accrued, absolute, contingent or otherwise) that would not, individually or in the aggregate, have a DM Material Adverse Effect.

SECTION 3.7 Litigation; Laws and Regulations. Except as would not, individually or in the aggregate, have a DM Material Adverse Effect:

(a) There are no (i) civil, criminal, regulatory or administrative actions, suits, claims, hearings, arbitrations, inquiries, subpoenas, investigations or proceedings (“Proceedings”) pending or, to the Knowledge of the DM Parties, threatened against or affecting the DM Group Entities, their assets, or any of the operations of the DM Group Entities related thereto or (ii) judgments, orders, decrees or injunctions of any Governmental Entity, whether at law or in equity (“Orders”), against or affecting the DM Group Entities, their assets, or any of the operations of the DM Group Entities related thereto.

(b) None of the DM Group Entities (i) is in violation of or in default under its Governing Documents or (ii) is in violation of any applicable Law, except in the case of each of clause (i) and (ii) for such violations or defaults that would not, individually or in the aggregate, have a DM Material Adverse Effect.

SECTION 3.8 No Adverse Changes. Except as disclosed in the DM SEC Reports or described in the DM Financial Statements, as applicable, with respect to the DM Group Entities:

(a) since December 31, 2017, there has not been a DM Material Adverse Effect; and

(b) since December 31, 2017, there has not been any material damage, destruction or loss to any material portion of the assets of the DM Group Entities, whether or not covered by insurance.

(c) since December 31, 2017, neither DM nor any other DM Group Entity has taken any action described in Section 5.1(a) that, if taken after the date of this Agreement and prior to the Effective Time without the prior written consent of Parent, would violate such provisions.

SECTION 3.9 Taxes.

SECTION 4.4 Capitalization.

(a) The authorized capital stock of Parent consists of 1,000,000,000 shares of Parent Common Stocks and 20,000,000 shares of preferred stock (such preferred stock, the “Parent Preferred Stock”). At the close of business on November 23, 2018, there were (A) 656,473,401 shares of Parent Common Stock issued and outstanding and (B) no shares of Parent Preferred Stock issued or outstanding. Except as set forth in the immediately preceding sentence, at the close of business on November 23, 2018, no shares of capital stock or other voting securities of Parent were issued or outstanding. Since November 23, 2018 to the date of this Agreement, (x) there have been no issuances by Parent of shares of capital stock or other voting securities of Parent other than pursuant to the exercise or vesting of equity awards under any Parent equity award plans or pursuant to Parent’s dividend reinvestment and direct stock purchase plan (“Dominion Energy Direct”), in each case, outstanding as of November 23, 2018 and (y) except as set forth on Section 4.4(a) of the Parent Disclosure Letter, there have been no issuances by Parent of options, warrants, other rights to acquire shares of capital stock of Parent or other rights that give the holder thereof any economic interest of a nature accruing to the Holders of Parent Common Stock. All outstanding shares of Parent Common Stock are, and all such shares of Parent Common Stock that may be issued prior to the Effective Time will be when issued, duly authorized, validly issued, fully paid and non-assessable and not subject to preemptive rights.

(b) As of the Execution Date, all of the outstanding capital stock, voting securities or other equity interests of each Parent Subsidiary owned directly or indirectly by the Parent Parties (i) are owned, beneficially and of record free and clear of all Liens and (ii) have been duly authorized and are validly issued, fully paid (with respect to Parent Subsidiaries that are limited liability companies or limited partnerships, to the extent required under the limited liability company agreement or limited partnership agreement of the applicable Parent Subsidiary) and nonassessable (with respect to Parent Subsidiaries that are limited liability companies or limited partnerships, except as such nonassessability may be affected by Sections 18-607 and 18-804 of the DLLCA or by Sections 17-303, 17-607 and 17-804 of the DRULPA and the Governing Documents of the applicable entity).

SECTION 4.5 SEC Documents; Internal Controls.

(a) Since January 1, 2017, all reports, including but not limited to the Annual Reports on Form 10-K, the Quarterly Reports on Form 10-Q and the Current Reports on Form 8-K (whether filed on a voluntary basis or otherwise), forms, schedules, certifications, prospectuses, registration statements and other documents required to be filed or furnished by Parent or any Parent Subsidiary with or to the SEC (the “Parent SEC Reports”) have been timely filed or furnished. For a period of at least twelve calendar months immediately prior to the Execution Date, all Parent SEC Reports have been filed in a timely manner. The Parent SEC Reports shall not include any reports required to be filed or furnished by any entity prior to such entity becoming a Parent Subsidiary. Each of the Parent SEC Reports (i) complied in all material respects with the requirements of applicable Law (including the Exchange Act, the Securities Act and the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act), and (ii) as of its effective date (in the case of Parent SEC Reports that are registration statements filed pursuant to the Securities Act) and as of its filing date did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except for any statements (x) in any Parent SEC Report that may have been modified by an amendment to such report or a subsequent report filed with the SEC prior to the Execution Date or (y) with respect to information supplied in writing by or on behalf of DM, as to which Parent makes no representation or warranty.

27

(b) There are no outstanding comments from, or unresolved issues raised by, the staff of the SEC with respect to the Parent SEC Reports. No enforcement action has been initiated against Parent relating to disclosures contained or omitted from any Parent SEC Report.

(c) Parent makes and keeps books, records, and accounts and has devised and maintains a system of internal controls, in each case, as required pursuant to Section 13(b)(2) under the Exchange Act. Parent has established and maintains disclosure controls and procedures and internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act and the applicable listing standards of the NYSE. Such disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by Parent in the reports that it files under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to its management as appropriate to allow timely decisions regarding required disclosure. Parent’s principal executive officer and its principal financial officer have disclosed, based on their most recent evaluation, to Parent’s auditors and the audit committee of the Parent Board (x) all significant deficiencies in the designation or operation of internal controls which could adversely affect Parent’s ability to record, process, summarize and report financial data and have identified for Parent’s auditors any material weakness in internal controls and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in Parent’s internal controls.

(d) Since January 1, 2017, the principal executive officer and principal financial officer of Parent have made all certifications (without qualification or exceptions to the matters certified, except as to Knowledge) required by the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, and the statements contained in any such certifications are complete and correct, and none of Parent or its officers have received notice from any Governmental Entity questioning or challenging the accuracy, completeness, form or manner of filing or submission of such certification. As of the Execution Date, and except as disclosed in a Parent SEC Report filed with the SEC prior to the Execution Date, Parent has no Knowledge of any material weaknesses in the design or operation of such internal controls over financial reporting.

SECTION 4.6 Financial Statements; Undisclosed Liabilities.

(a) The consolidated financial statements of Parent included in the Parent SEC Documents (the “Parent Financial Statements”) as of their respective dates (if amended, as of the date of the last such amendment) comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared in accordance with GAAP applied on a consistent basis throughout the periods covered thereby (except as may be indicated in the notes thereto) and present fairly in all material respects the consolidated financial position of Parent as of such dates and the consolidated results of operations and cash flows of Parent for such periods, except as otherwise noted therein. Except as set forth in the Parent Financial Statements, there are no off-balance sheet arrangements that would, individually or in the aggregate, have a Parent Material Adverse Effect. Parent has not had any disagreement with its independent public accounting firm that required disclosure in the Parent SEC Reports.

28

(a) There are no (i) Proceedings pending or, to the Knowledge of the Parent Parties, threatened against or affecting the Parent Group Entities, their assets, or any of the operations of the Parent Group Entities related thereto or (ii) Orders against or affecting the Parent Group Entities, their assets, or any of the operations of the Parent Group Entities related thereto.

(b) None of the Parent Group Entities (i) is in violation of or in default under its Governing Documents or (ii) is in violation of any applicable Law, except in the case of each of clause (i) and (ii) for such violations or defaults that would not, individually or in the aggregate, have a Parent Material Adverse Effect.

SECTION 4.8 No Adverse Changes. Except as disclosed in the Parent SEC Reports or described in the Parent Financial Statements, as applicable, with respect to the Parent Group Entities:

(a) since December 31, 2017, there has not been a Parent Material Adverse Effect;

(b) since December 31, 2017, there has not been any material damage, destruction or loss to any material portion of the assets of the Parent Group Entities, whether or not covered by insurance; and

(c) since December 31, 2017, neither Parent nor any other Parent Group Entity has taken any action described in Section 5.1(b) that, if taken after the date of this Agreement and prior to the Effective Time without the prior written consent of DM, would violate such provisions.

SECTION 4.9 Taxes. Except as would not, individually or in the aggregate, have a Parent Material Adverse Effect, (a) all Tax Returns required to be filed by or with respect to Parent or any of the Parent Subsidiaries or their assets have been filed on a timely basis (taking into account all extensions of due dates); (b) all Taxes owed by Parent or any of the Parent Subsidiaries, which are or have become due, have been timely paid in full; (c) there are no Liens on any of the assets of Parent or any of the Parent Subsidiaries that arose in connection with any failure (or alleged failure) to pay any Tax on any of such assets, other than Permitted Liens; (d) there is no pending Proceeding for assessment or collection of Taxes and no Tax assessment, deficiency or adjustment has been asserted or proposed with respect to Parent or any of the Parent Subsidiaries or their assets, and (e) Parent has not constituted either a “distributing corporation” or a “controlled corporation” in a distribution of stock intended to qualify for tax-free treatment under Section 355 of the Code in the two years prior to the date of this Agreement or in a distribution which could otherwise constitute part of a “plan” or “series of related transactions” (within the meaning of Section 355(e) of the Code) in conjunction with the transactions contemplated by this Agreement.

29

SECTION 4.10 Brokers and Other Advisors. No broker, investment banker, financial advisor or other Person is entitled to any broker’s, finder’s or financial advisor’s fee or commission in connection with the Merger and the other transactions contemplated by this Agreement based upon arrangements made by or on behalf of Parent or Merger Sub.

SECTION 4.11 Information Supplied. None of the information supplied (or to be supplied) in writing by or on behalf of Parent specifically for inclusion or incorporation by reference in the Registration Statement will, at the time the Registration Statement, or any amendment or supplement thereto, is filed with the SEC or at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they are made, not misleading. Notwithstanding the foregoing, Parent makes no representation or warranty with respect to information supplied by or on behalf of DM for inclusion or incorporation by reference in any of the foregoing documents.

SECTION 4.12 Waivers and Disclaimers. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT, EXCEPT FOR THE EXPRESS REPRESENTATIONS AND WARRANTIES AND OTHER COVENANTS AND AGREEMENTS MADE BY THE PARENT PARTIES IN THIS AGREEMENT, THE PARENT PARTIES HAVE NOT MADE, DO NOT MAKE, AND SPECIFICALLY NEGATE AND DISCLAIM ANY REPRESENTATIONS, WARRANTIES, PROMISES, COVENANTS, AGREEMENTS OR GUARANTIES OF ANY KIND OR CHARACTER WHATSOEVER, WHETHER EXPRESS, IMPLIED OR STATUTORY, ORAL OR WRITTEN, PAST OR PRESENT REGARDING (A) THE VALUE, NATURE, QUALITY OR CONDITION OF THEIR ASSETS INCLUDING, WITHOUT LIMITATION, THE WATER, SOIL, GEOLOGY OR ENVIRONMENTAL CONDITION OF THEIR ASSETS GENERALLY, INCLUDING THE PRESENCE OR LACK OF HAZARDOUS SUBSTANCES OR OTHER MATTERS ON THEIR ASSETS, (B) THE INCOME TO BE DERIVED FROM THEIR ASSETS, (C) THE SUITABILITY OF THEIR ASSETS FOR ANY AND ALL ACTIVITIES AND USES THAT MAY BE CONDUCTED THEREON, (D) THE COMPLIANCE OF OR BY THEIR ASSETS OR THEIR OPERATION WITH ANY LAWS (INCLUDING WITHOUT LIMITATION ANY ZONING, ENVIRONMENTAL PROTECTION, POLLUTION OR LAND USE LAWS, RULES, REGULATIONS, ORDERS OR REQUIREMENTS), OR (E) THE HABITABILITY, MERCHANTABILITY, MARKETABILITY, PROFITABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF THEIR ASSETS.

THE PROVISIONS OF THIS SECTION 4.12 HAVE BEEN NEGOTIATED BY THE PARTIES AFTER DUE CONSIDERATION AND ARE INTENDED TO BE A COMPLETE EXCLUSION AND NEGATION OF ANY REPRESENTATIONS OR WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, WITH RESPECT TO THE PARENT GROUP ENTITIES, THEIR BUSINESSES OR THEIR ASSETS THAT MAY ARISE PURSUANT TO ANY LAW NOW OR HEREAFTER IN EFFECT, OR OTHERWISE, EXCEPT AS SET FORTH IN THIS AGREEMENT.

Each of the Parent Parties and the DM Parties further agrees that, if it shall become aware prior to the Closing Date of any information that would cause any of the statements in the Registration Statement or the Consent Statement/Prospectus to be false or misleading with respect to any material fact, or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not false or misleading, it will promptly inform the other party thereof and take the necessary steps to correct such information in an amendment or supplement to the Registration Statement or Consent Statement/Prospectus.

34

(c) Each of DM and Parent shall (1) promptly notify the other of receipt of any comments from the SEC or its staff or any other applicable government official and of any requests by the SEC or its staff or any other applicable government official for amendments or supplements to any of the filings with the SEC in connection with the Merger and other transactions contemplated hereby or for additional information and (2) promptly supply the other with copies of all correspondence between DM or any of its representatives, or Parent or any of its representatives, as the case may be, on the one hand, and the SEC or its staff or any other applicable government official, on the other hand, with respect thereto.

From and after the Execution Date, upon the terms and subject to the conditions hereof, each of the parties hereto shall use its reasonable best efforts to (i) take, or cause to be taken, all appropriate action, and to do or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate and make effective the transactions contemplated by this Agreement as promptly as practicable, (ii) defend any lawsuits or other Proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated by this Agreement or seek to have lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby, including the Merger and (iii) obtain promptly all approvals, consents, clearances, expirations or terminations of waiting periods, registrations, permits, authorizations and other confirmations from any Governmental Entity or third party necessary, proper or advisable to consummate the transactions contemplated hereby.

the extent not previously issued or made in accordance with this Agreement) (other than public announcements at industry road shows and conferences or as may be required by applicable Law or by obligations pursuant to any listing agreement with the NYSE, in which event the party making the public announcement or press release shall, to the extent practicable, notify Parent and DM General Partner in advance of such public announcement or press release) without the prior approval of Parent and DM General Partner, which approval shall not be unreasonably withheld, delayed or conditioned.

SECTION 5.7 Regulatory Issues. DM and Parent shall cooperate fully with respect to any filing, submission or communication with a Governmental Entity having jurisdiction over the Merger.

The parties will prepare and file all Tax Returns consistent with the foregoing and will not take any inconsistent position on any Tax Return, or during the course of any audit, litigation or other proceeding with respect to Taxes, except as otherwise required by applicable Law following a final determination by a court of competent jurisdiction or other administrative settlement with or final administrative decision by the relevant Governmental Entity.

SECTION 5.9 D&O Insurance.

(a) For a period of six years after the Effective Time, to the fullest extent permitted under applicable Laws, Parent and the Surviving Entity shall, and shall cause the DM Group Entities to, (i) indemnify and hold harmless each DM D&O Indemnified Party against any reasonable costs or expenses (including reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or

36

participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Proceeding arising from acts or omissions occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement), including any Proceeding relating to a claim for indemnification or advancement brought by a DM D&O Indemnified Party), judgments, fines, losses, claims, damages or liabilities, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) in connection with any actual or threatened Proceeding arising from acts or omissions occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement), and, upon receipt by Parent of an undertaking by or on behalf of the DM D&O Indemnified Party to repay such amount if it shall be determined in a final and non-appealable judgment entered by a court of competent jurisdiction that the DM D&O Indemnified Party is not entitled to be indemnified, provide advancement of expenses with respect to each of the foregoing to, all DM D&O Indemnified Parties and (ii) honor all rights to indemnification, advancement of expenses, elimination of liability and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement) now existing in favor of the DM D&O Indemnified Parties as provided in the Governing Documents of any DM Group Entity, under applicable Delaware Law or otherwise, and shall ensure that the Governing Documents of DM and DM General Partner (or their successor entities) shall, for a period of six years following the Effective Time, contain provisions substantially no less advantageous with respect to indemnification, advancement of expenses, elimination of liability and exculpation of their present and former directors, officers, employees and agents than are set forth in the Governing Documents of DM and DM General Partner as of the Execution Date. Any right of a DM D&O Indemnified Party pursuant to this Section 5.9(a) shall not be amended, repealed, terminated or otherwise modified at any time in a manner that would adversely affect the rights of such DM D&O Indemnified Party as provided herein, and shall be enforceable by such DM D&O Indemnified Party and their respective heirs and representatives against Parent and its respective successors and assigns.

(b) For a period of six years after the Effective Time, Parent shall maintain officers’ and directors’ liability insurance with a nationally reputable carrier covering each DM D&O Indemnified Party who is or at any time prior to the Effective Time was covered by the existing officers’ and directors’ liability insurance applicable to the DM Group Entities (“D&O Insurance”), on terms substantially no less advantageous to the DM D&O Indemnified Parties, as applicable, than such existing insurance with respect to acts or omissions, or alleged acts or omissions, at or prior to the Effective Time (whether claims, actions or other Proceedings relating thereto are commenced, asserted or claimed before or after the Effective Time); provided, however, that Parent shall not be required to pay an annual premium for the D&O Insurance for the DM D&O Indemnified Parties in excess of 300% of the current annual premium currently paid by the DM Group Entities for such insurance, but shall purchase as much of such coverage as possible for such applicable amount. Parent shall have the right to cause such coverage to be extended under the applicable D&O Insurance by obtaining a six-year “tail” policy on terms and conditions no less advantageous to the DM D&O Indemnified Parties than the existing D&O Insurance, and such “tail” policy shall satisfy the provisions of this Section 5.9.

37

(c) The provisions of this Section 5.9 shall survive the consummation of the Merger and the other transactions contemplated by this Agreement for a period of six years and expressly are intended to benefit each of the DM D&O Indemnified Parties; provided, however, that in the event that any claim or claims for indemnification or advancement set forth in this Section 5.9 are asserted or made within such six-year period, all rights to indemnification and advancement in respect of any such claim or claims shall continue until disposition of all such claims. The rights of any DM D&O Indemnified Party under this Section 5.9 shall be in addition to any other rights such DM D&O Indemnified Party may have under the Governing Documents of any DM Group Entity or applicable Law.

(d) In the event Parent or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then and in either such case, Parent shall cause proper provision to be made so that its successors and assigns, as the case may be, shall assume the obligations set forth in this Section 5.9.

The DM Parties hereby consent to the Parent Group Entities’ use of and reliance on any audited or unaudited financial statements, including the DM Financial Statements, relating to the DM Group Entities reasonably requested by the Parent Parties to be used in any financing or other activities of the Parent Parties permitted hereby, including any filings that the Parent Parties desire to make with the SEC. In addition, the DM Parties will use reasonable best efforts, at the Parent Parties’ sole cost and expense, to obtain the consents of Deloitte & Touche LLP to the inclusion of the financial statements referenced above in appropriate filings with the SEC. Prior to the Closing, the DM Parties will provide the Parent Parties such information, and make available such personnel, as the Parent Parties may reasonably request in order to assist any of the Parent Group Entities in connection with financing activities permitted hereby, including any public offerings to be registered under the Securities Act or private offerings.

SECTION 5.11 Distributions. After the date of this Agreement until the Effective Time, the DM General Partner shall (and Parent shall directly or indirectly cause its representatives on the DM Board to) determine, declare and cause DM to pay regular quarterly cash distributions on the DM Common Units for each quarter in accordance with the DM Partnership Agreement in the ordinary course and consistent with past practice, including with respect to amount and timing of record dates and payment dates; provided, however, that, subject to applicable Law, any such regular quarterly distribution shall not be less than or exceed the amounts set forth on Section 5.11 of the DM Disclosure Letter without the separate determination and approval of the DM Conflicts Committee made in accordance with the DM Partnership Agreement and their duties as directors of the DM Board. The DM General Partner shall (and Parent shall directly or indirectly cause its representatives on the DM Board to) designate the record and payment dates for the DM Fourth Quarter Distribution so that such record and payment dates precede the Effective Time so as to permit the payment, not later than immediately prior to the Effective Time, of the DM Fourth Quarter Distribution to the Holders of DM Public Units on such record date.

SECTION 5.12 Section 16 Matters. Prior to the Effective Time, the DM Board and the Parent Board shall take all such steps as may be necessary or appropriate to cause the transactions contemplated by this Agreement, including any dispositions of DM Units (including derivative securities with respect to such DM Units) or acquisitions of shares of Parent Common Stock (including derivative securities with respect to such shares Parent Common Stock) resulting from

38

the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to DM, or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

SECTION 5.13 Conflicts Committee. Prior to the Effective Time, none of the DM Group Entities shall, without the consent of the DM Conflicts Committee, eliminate the DM Conflicts Committee, or revoke or diminish the authority of the DM Conflicts Committee, or remove or cause the removal of any director of the DM Board that is a member of the DM Conflicts Committee either as a member of such board or such committee without the affirmative vote of the members of the DM Board, including the affirmative vote of each of the other members of the DM Conflicts Committee. For the avoidance of doubt, this Section 5.13 shall not apply to the filling in accordance with the provisions of the applicable Governing Documents of any vacancies caused by the death, incapacity or resignation of any director.

SECTION 5.14 Takeover Laws. Parent shall not, and shall cause its Subsidiaries not to, take any action that would, or would reasonably be expected to, cause any Takeover Law to become applicable to this Agreement, the Merger, the Parent Stock Issuance or the other transactions contemplated hereby or related thereto. If any Takeover Law shall become applicable to this Agreement, the Merger, the Parent Stock Issuance or the other transactions contemplated hereby or related thereto, Parent and the Parent Board shall grant such approvals and shall use reasonable best efforts to take such actions so that the transactions contemplated hereby, including the Merger and the Parent Stock Issuance, may be consummated as promptly as practicable on the terms contemplated hereby and otherwise use reasonable best efforts to eliminate or minimize the effects of such statute or regulation on the transactions contemplated hereby, including the Merger and the Parent Stock Issuance.

SECTION 8.2 Governing Law; Jurisdiction; Waiver of Jury Trial. To the maximum extent permitted by applicable Law, the provisions of this Agreement shall be governed by and construed and enforced in accordance with the Laws of the State of Delaware, without regard to principles of conflicts of law. Each of the parties hereto agrees that this Agreement involves at least $100,000 and that this Agreement has been entered into in express reliance upon 6 Del. C. § 2708. Each of the parties hereto irrevocably and unconditionally confirms and agrees that it is and shall continue to be (a) subject to the jurisdiction of the courts of the State of Delaware and of the federal courts sitting in the State of Delaware, and (b) subject to service of process in the State of Delaware. Each party hereto hereby irrevocably and unconditionally (i) consents and submits to the exclusive personal jurisdiction and venue of the Delaware Court of Chancery (or, solely if the Delaware Court of Chancery declines to accept jurisdiction over any matter, any federal or state court located in the State of Delaware) (the “Delaware Courts”) for any actions, suits or proceedings arising out of or relating to this Agreement or the transactions contemplated by this Agreement (and agrees not to commence any litigation relating thereto except in such courts), (ii) waives any objection to the laying of venue of any such litigation in the Delaware Courts and agrees not to plead or claim in any Delaware Court that such litigation brought therein has been brought in any inconvenient forum, (c) acknowledges and agrees that any controversy that may arise under this Agreement is likely to involve complicated and difficult issues, and therefore each such party hereby irrevocably and unconditionally waives any right such party may have to a trial by jury in respect of any litigation directly or indirectly arising or relating to this Agreement or the transactions contemplated by this Agreement, and (d) agrees to service of process upon such party in any such action or proceeding shall be effective if such process is given as a notice in accordance with Section 8.1 or in any manner prescribed by the Laws of the State of Delaware. Nothing in this Section 8.2 shall affect the right of any party to serve legal process in any other manner permitted by Law.

SECTION 8.3 Entire Agreement; Amendments, Consents and Waivers. This Agreement, the Support Agreement, and the exhibits and schedules hereto and thereto constitute the entire agreement between and among the parties hereto pertaining to the subject matter hereof and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties, and there are no warranties, representations or other agreements between or among the parties in connection with the subject matter hereof except as set forth specifically herein or contemplated hereby. Except as expressly set forth in this Agreement (including the representations and warranties set forth in Articles III and IV), (a) the parties acknowledge and agree that neither the DM Group Entities nor any other Person has made, and the Parent Group Entities are not relying upon, any covenant, representation or warranty, expressed or implied, as to the DM Group Entities or as to the accuracy or completeness of any information regarding any DM Group Entity furnished or made available to any Parent Group Entity, (b) the parties hereto acknowledge and agree that, except as set forth in this Agreement, neither the Parent Group Entities nor any other Person has made, and the DM Group Entities are not relying upon, any covenant, representation or warranty, expressed or implied, as to the Parent Group Entities or as to the accuracy or completeness of any information regarding any Parent Group Entity furnished or made available to any DM Group Entity, and (c) the DM Parties and the Parent Parties shall not have or be subject to any liability to any Parent Group Entity or any other Person or any DM Group Entity or any other Person, as applicable, or any other remedy in connection herewith, based upon the distribution to any Parent Group Entity or any DM Group Entity of, or any Parent Group Entity’s or any DM Group Entity’s use of or reliance on, any such information or any information,

45

documents or material made available to the Parent Group Parties or DM Group Parties, as applicable, in any “data rooms,” “virtual data rooms,” management presentations or in any other form in expectation of, or in connection with, the transactions contemplated hereby. Subject to compliance with applicable Law, prior to the Effective Time, any provision of this Agreement may be (a) consented to or waived in writing by the party benefited by the provision or (b) amended or modified at any time by an agreement in writing by the parties hereto; provided, however, that, in addition to any other approvals required by the DM Parties’ constituent documents or under this Agreement, the foregoing consents, waivers, amendments or modifications in clauses (a) and (b), and any decision or determination by DM to (x) terminate this Agreement pursuant to Section 7.2 or Section 7.3 or (y) enforce this Agreement (including pursuant to Section 7.8), must be approved by, in the case of consents, waivers, amendments or modifications, or such decisions or determinations, by any DM Party, by the DM Board, and the DM Conflicts Committee. No amendment, supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the parties hereto. The failure of a party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the future. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided.

SECTION 8.4 Binding Effect; No Third-Party Beneficiaries; and Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. Nothing in this Agreement, express or implied, is intended to confer upon any Person other than the parties hereto and their respective permitted successors and assigns, any rights, benefits or obligations hereunder, except (i) as provided in Section 5.9, (ii) for the right of the Holders of DM Units to receive the Merger Consideration, any Fractional Share Payment and any distributions or dividends payable pursuant to Section 2.2(c) or Section 2.2(d) after the Closing (a claim by the Holders of DM Units with respect to which may not be made unless and until the Closing shall have occurred) and (iii) for the right of the Holders of DM Restricted Unit Awards to receive Parent Awards pursuant to Section 2.3 after the Closing (a claim by the Holders of DM Restricted Unit Awards with respect to which may not be made unless and until the Closing shall have occurred). No party hereto may assign, transfer, dispose of or otherwise alienate this Agreement or any of its rights, interests or obligations under this Agreement (whether by operation of law or otherwise). Any attempted assignment, transfer, disposition or alienation in violation of this Agreement shall be null, void and ineffective.

SECTION 8.5 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of applicable Law, or public policy, all other conditions or provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement are not affected in any matter materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the fullest extent possible.

46

SECTION 8.6 Counterparts. This Agreement may be executed in multiple counterparts each of which shall be deemed an original and all of which shall constitute one instrument.
