The value of such Restricted Securities shall not bear any interest owing to the passage of time.

10. Payment of Taxes. To the extent that the receipt, vesting or settlement of the Restricted Securities results in compensation income or wages to you for federal, state, local and/or foreign tax purposes, you shall make arrangements satisfactory to the Company for the satisfaction of obligations for the payment of withholding taxes and other tax obligations relating to the Restricted Securities, which arrangements include the delivery of cash or cash equivalents, Class C Shares and/or OpCo Units (including previously owned Class C Shares and/or OpCo Units, net settlement, net early settlement, a broker-assisted sale, or other cashless withholding or reduction of the amount of Class C Shares and/or OpCo Units otherwise issuable or delivered pursuant to the Restricted Securities), other property, or any other legal consideration the Board deems appropriate. If such tax obligations are satisfied through net settlement, net early settlement or the surrender of previously owned Class C Shares and/or OpCo Units, the maximum number of Class C Shares and/or OpCo Units that may be so withheld (or surrendered) shall be the number of Class C Shares and/or OpCo Units that have an aggregate Fair Market Value (as defined below) on the date of withholding or surrender equal to the aggregate amount of such tax liabilities determined based on the greatest withholding rates for federal, state, local and/or foreign tax purposes, including payroll taxes, that may be utilized without creating adverse accounting treatment for the Sponsors or the Company with respect to the Restricted Securities, as determined by the Board. You acknowledge that there may be adverse tax consequences upon the receipt, vesting or settlement of the Restricted Securities or disposition of the underlying shares and/or units and that you have been advised, and hereby are advised, to consult a tax advisor. You represent that you are in no manner relying on the Board, the Sponsors, DPM, the Corporation or OpCo or any of their respective affiliates or any of their respective managers, directors, officers, employees or authorized representatives (including, without limitation, attorneys, accountants, consultants, bankers, lenders, prospective lenders and financial representatives) for tax advice or an assessment of such tax consequences.

11. Acknowledgement. You acknowledge and agree that (a) you are not relying upon any determination by the Sponsors, DPM, the Corporation or OpCo, their respective affiliates, or any of their respective employees, directors, officers, attorneys, or agents (collectively, the “Company Parties”) of the Fair Market Value (as defined below) of the Class C Shares and OpCo Units on the Effective Date, (b) you are not relying upon any written or oral statement or representation of the Company Parties regarding the tax effects associated with your execution of this Agreement and your receipt, holding, and vesting of the Restricted Securities, and (c) in deciding to enter into this Agreement, you are relying on your own judgment and the judgment of the professionals of your choice with whom you have consulted. You hereby release, acquit and forever discharge the Company Parties from all actions, causes of actions, suits, debts, obligations, liabilities, claims, damages, losses, costs, and expenses of any nature whatsoever, known or unknown, on account of, arising out of, or in any way related to the tax effects associated with your execution of the Agreement and your receipt, holding and exercise of the Restricted Securities. For purposes of this Agreement, “Fair Market Value” means, as of any specified date, the amount determined by the Board in its discretion in such manner as it deems appropriate, taking into consideration all factors the Board deems appropriate including without limitation.

12. Compliance with Securities Law. Notwithstanding any provision of this Agreement to the contrary, the issuance of Class C Shares and/or OpCo Units (including the Restricted Securities) will be subject to compliance with all applicable requirements of federal, state, or foreign law with respect to such securities and with the requirements of any stock exchange or market system upon which the Class C Shares and/or OpCo Units (or any security into which such securities may be exchanged) may then be listed. No Class C Shares and/or OpCo Units will be issued hereunder if such issuance would constitute a violation of any applicable federal, state, or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Class C Shares and/or OpCo Units (or any security into which such securities may be exchanged) may then be listed. In addition, Class C Shares and OpCo Units will not be issued hereunder unless (a) a registration statement under the Securities Act of 1933, as amended (the “Act”), is at the time of issuance in effect with respect to the shares issued or (b) in the opinion of legal counsel to the Company, the shares issued may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares and units subject to this Agreement will relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority has not been obtained. As a condition to any issuance hereunder, the Company may require you to satisfy any qualifications that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect to such compliance as may be requested by the Company. From time to time, the Board and appropriate officers of the Company are authorized to undertake (or cause to be undertaken) the actions necessary and appropriate to file required documents with governmental authorities, stock exchanges, and other appropriate persons to make Class C Shares and/or OpCo Units available for issuance.

13. Legends. The Company or OpCo, as applicable, shall place, or cause to be placed, legends referencing the restrictions imposed on the Restricted Securities pursuant to this Agreement on all certificates (or book-entry notations) representing Restricted Securities issued with respect to this Agreement.

14. No Right to Continued Employment. Nothing in this Agreement confers upon you the right to remain employed by the Company or any of its affiliates, or interfere in any way with the rights of the Company or such affiliate to terminate your employment relationship at any time.

15. Furnish Information. You agree to furnish to the Sponsors or the Company, as applicable, all information requested by the Sponsors or the Company to enable it to comply with any reporting or other requirements imposed upon the Sponsors or the Company by or under any applicable statute or regulation.

The Company may require you or your legal representative, heir, legatee, or distributee, as a condition precedent to such payment or issuance, to execute a release and receipt therefor in such form as it shall determine.

24. Severability.
