Enforcement. The parties hereto agree that irreparable damage would occur for which there is not an adequate remedy at law in the event of a breach or threatened breach of this Letter Agreement, that the damages resulting from any such breach or threatened breach would be material but not readily susceptible to being measured in monetary terms, and that any remedy at law (including the payment of damages) would be inadequate as a result of such breach or threatened breach.

Severability. The invalidity or unenforceability of any provision or provisions of this Letter Agreement shall not affect the validity or enforceability of any other provision of this Letter Agreement. If any of the provisions of this Letter Agreement shall be determined to be invalid under the laws of any applicable jurisdiction, such invalidity shall not invalidate all of the provisions of this Letter Agreement, but rather the Letter Agreement shall be construed insofar as the laws of that jurisdiction are concerned, as not containing invalid or contravening provisions, and the rights and obligations of the parties shall otherwise be enforced to the fullest extent possible. If, however, any such invalid or contravening provisions relate to Sections 9 or 10, then such Sections shall be construed as providing for the maximum protections available to an employer or service recipient which the laws of that jurisdiction permit.

This Letter Agreement shall be interpreted in accordance with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and any Treasury Regulations or other Department of Treasury guidance issued thereunder (“Section 409A”). The parties intend that any amounts payable hereunder will be compliant with or exempt from Section 409A.

Excess Parachute Payments. Notwithstanding anything in this Letter Agreement to the contrary, and subject to the application of this Section 14, if any of the payments or benefits provided or to be provided by EGH, WME or any member of the Employer Group to Employee or for Employee’s benefit pursuant to the terms of this Letter Agreement or otherwise (“Covered Payments”) are determined to constitute “excess parachute payments” within the meaning of Section 280G of the Code and would, but for this Section 14 be subject to the excise tax imposed under Section 4999 of the Code (or any successor provision thereto) or any similar tax imposed by state or local law or any interest or penalties with respect to such taxes (collectively, the “Excise Tax”), then the Covered Payments shall be reduced (but not below zero) to the minimum extent necessary to ensure that no portion of the Covered Payments is subject to the Excise Tax; provided, however, that EGH or, as applicable, WME, agrees to, and agrees to cause any other relevant member of the Employer Group to, submit to a stockholder vote your right to receive the Covered Payments and use commercially reasonable best efforts to obtain shareholder approval of any payments or benefits in excess of the safe harbor level in accordance with Q&A #7 of Section 280G of the Code (the “Shareholder Approval Exception”), to the extent applicable and available, such that there will be no such loss of deductibility under Code Section 280G or imposition of tax under Section 4999 of the Code.

IN FURTHERANCE OF THE FOREGOING, THE INTERNAL LAW OF THE STATE OF DELAWARE WILL CONTROL THE INTERPRETATION AND CONSTRUCTION OF THIS LETTER AGREEMENT, EVEN IF UNDER SUCH JURISDICTION’S CHOICE OF LAW OR CONFLICT OF LAWS ANALYSIS, THE SUBSTANTIVE LAW OF SOME OTHER JURISDICTION WOULD ORDINARILY APPLY.

This Letter Agreement may not be amended, modified, rescinded or waived except in writing executed by the parties hereto.

Other than Section 7, this Letter Agreement shall automatically terminate upon the effective termination of the Merger Agreement, and shall be void ab initio and shall have been of no force or effect in the event the Merger Agreement is terminated or the Closing otherwise does not occur.

Waiver. Failure of you or any member of the Employer Group to enforce any provision or provisions of this Letter Agreement shall not in any way be construed as a waiver of any provision or provisions, or prevent you or any member of the Employer Group from thereafter enforcing each and every other provision of this Letter Agreement.

All notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally or by commercial delivery service, or sent via telecopy (receipt confirmed) to the parties at the following addresses or facsimile numbers (or at such other address or telecopy numbers for a party as shall be specified by like notice):

Taxes.

Set Off. Other than as set forth in Section 5, EGH, EOC and/or WME’s obligation to pay you the amounts provided and to make the arrangements provided hereunder shall be subject to set-off, counterclaim or recoupment of any fixed and determined amounts owed and payable within the next six months by you to the Employer Group, except to the extent any such set-off, counterclaim or recoupment would violate, or result in the imposition of a tax under Section 409A, in which case such right shall be null and void.

Advice of Counsel and Construction. You acknowledge that you had the opportunity to be represented by counsel in the negotiation and execution of this Letter Agreement. Accordingly, the rule of construction of contract language against the drafting party is hereby waived by each party to this Letter Agreement.

Successors and Assigns. This Letter Agreement is personal to you and without the prior written consent of EGH, EOC and/or WME, as applicable, shall not be assignable by you otherwise than by will or the laws of descent and distribution (except that the applicable governing equity documentation will provide that the rights in respect of any Equity Interests that are transferred to any of your Permitted Transferees may be enforced by such Permitted Transferees, but solely in respect of such transferred Equity Interests). This Letter Agreement shall be assignable by EGH, EOC, and/or WME, as applicable, to any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Employer Group.

EGH will (or shall cause an affiliate to) reimburse you for any reasonable travel and out-of-pocket expenses incurred by you in providing such cooperation and, to the extent the Employer Group is not otherwise continuing to pay you, EGH shall (or shall cause an affiliate to) pay you at a daily rate equal to $23,077. Furthermore, any such cooperation occurring after the termination of your services shall be scheduled to the extent reasonably practicable so as not to unreasonably interfere with your business or personal affairs.

Allocations. For U.S. federal income tax purposes, EOC shall continue its historic practice with respect to partnership liability allocations in a manner that would not reasonably be expected to result in a net decrease to your direct or indirect share of partnership liabilities following the Effective Time to the maximum extent permitted by law and applicable treasury regulations other than as a result of a net decrease in EOC’s liabilities or a net decrease in a partner’s direct or indirect interest in EOC.
