Deferred Vesting of Equity Awards

On January 14, 2014, the Board of Directors (the “Partnership Board”) of Crosstex Energy GP, LLC, the general partner of Crosstex Energy, L.P. (the “Partnership”), and the Board of Directors (the “Corporation Board”) of Crosstex Energy, Inc. (the “Corporation” and, together with the Partnership, the “Crosstex Companies”), upon the recommendation of their respective compensation committees, authorized the Crosstex Companies to approach certain employees of the Crosstex Companies, including Messrs. William W. Davis and Stan Golemon (each of whom is a named executive officer), to propose that they waive their right to accelerated vesting with respect to 50% of their currently unvested equity awards (the “Waiver Awards”) granted under the Crosstex Energy GP, LLC Long-Term Incentive Plan, as amended and restated on May 9, 2013 (the “GP LTIP”), and the Crosstex Energy, Inc. 2009 Long-Term Incentive Plan, as amended and restated on May 9, 2013 (the “Corporation LTIP”).  Eligible employees who agree to the waiver are referred to herein as “Electing Employees.”

The Crosstex Companies’ proposal regarding the Waiver Awards was made pursuant to the terms of (i) the Agreement and Plan of Merger, dated as of October 21, 2013 (the “Merger Agreement”), by and among the Corporation, EnLink Midstream, LLC, a new holding company (formerly known as New Public Rangers, L.L.C.) (“EnLink Midstream”), Devon Energy Corporation (“Devon”) and certain other wholly-owned subsidiaries of Devon, pursuant to which, among other things, a wholly-owned subsidiary of EnLink Midstream will merge with and into the Corporation, with the Corporation surviving as a wholly-owned subsidiary of EnLink Midstream (the “Crosstex merger”), and (ii) the Contribution Agreement, dated as of October 21, 2013 (the “Contribution Agreement”), by and among the Partnership, Devon and certain of their wholly-owned subsidiaries.

Each Electing Employee’s Waiver Awards will be amended, effective immediately prior to the closing (the “Closing”) of the Crosstex merger to provide that such awards will not vest at such time but will vest on the second anniversary of the Closing.  Upon vesting, the Waiver Awards will entitle the Electing Employee to (i) the number of Partnership common units equal to the number of Partnership common units subject to such Waiver Awards and/or (ii) the number of EnLink Midstream common units equal to the number of shares of the Corporation’s common stock (the “Common Stock”) subject to the Waiver Awards, as applicable.

Pursuant to the Merger Agreement and the Contribution Agreement, and in accordance with the change in control provisions of the Corporation LTIP and the GP LTIP, the remaining 50% of the unvested equity awards in the Crosstex Companies held by each Electing Employee will vest immediately prior to the Closing.

As consideration for agreeing to waive the right to accelerated vesting with respect to the Waiver Awards, each Electing Employee will receive (i) a new restricted incentive units award under the GP LTIP for a number of Partnership common units equal to 50% of the Partnership

2

common units subject to the applicable Waiver Awards (rounded up, as necessary, to the nearest whole number of Partnership common units) and (ii) a new restricted incentive units award under the EnLink Midstream, LLC 2014 Long-Term Incentive Plan, which is expected to be adopted by the Board of Directors of the manager of EnLink Midstream and approved by the unitholder of EnLink Midstream prior to the Closing, for a number of EnLink Midstream common units equal to (1) 50% of the shares of Common Stock subject to the applicable Waiver Awards plus (2) an amount of EnLink Midstream common units to be determined by dividing (x) the product of the per share cash consideration to be paid to the Corporation’s stockholders pursuant to the Crosstex merger (which consideration will be equal to $100,000,000 divided by the number of shares of Common Stock issued and outstanding immediately prior to the Closing) and the number of shares of Common Stock subject to the applicable Waiver Awards by (y) the closing price of the EnLink Midstream common units on the first day of trading following the Closing (in each case rounded up, as necessary, to the nearest whole number of EnLink Midstream common units) (collectively, the “New Awards”).  The New Awards will be awarded following the Closing and will vest on the second anniversary of the Closing (unless a qualifying termination (as defined in the applicable award agreement) occurs during such two-year period).  Eligible employees must elect whether to agree to the terms of the waiver no later than January 31, 2014.

Messrs. Barry E. Davis, Michael J. Garberding and Joe A. Davis, each of whom is a named executive officer, previously agreed to waive the right to accelerated vesting with respect to their awards under the GP LTIP and the Corporation LTIP.  The following are the approximate, current cash values of the equity awards that Messrs. Barry E. Davis, Michael J. Garberding and Joe A. Davis waived, respectively: $6,867,993; $5,214,979; and $3,047,359.  These values assume a price per common unit of the Partnership equal to $26.55 and a price per share of common stock of the Corporation equal to $32.49, each of which is the average closing price per common unit or share of common stock, as applicable, over the five business days following the public announcement of the transactions with Devon.   These individuals will not receive the waiver consideration to be provided to Electing Employees described above. Instead, on January 14, 2014, the Partnership Board and the Corporation Board, upon the recommendation of their respective compensation committees, approved and authorized the Crosstex Companies to fund a cash bonus pool to provide cash awards to Messrs. Barry E. Davis, Joe A. Davis and Michael J. Garberding as consideration for such waivers. The aggregate amount to be awarded pursuant to this bonus pool is approximately $600,000 and will be allocated among these individuals prior to the Closing. Allocations of any bonus amounts to Mr. Barry E. Davis will be made by the compensation committees, and allocations to Messrs. Michael J. Garberding and Joe A. Davis will be subject to the review and approval of the compensation committees and the Partnership Board and the Corporation Board, as applicable.  Any such cash bonus awards will be contingent upon the Closing.

Transaction Bonus Plan

Also on January 14, 2014, the Partnership Board, upon the recommendation of its compensation committee, approved and authorized the Partnership to fund a cash bonus plan in an aggregate amount of up to $10.0 million (the “Transaction Bonus Plan”) to reward a broad base of employees, including the named executive officers of the Crosstex Companies, for the transactions with Devon.  Any awards made under the Transaction Bonus Plan will be contingent upon the Closing.  The final amount of the Transaction Bonus Plan will be determined prior to the Closing and then will be

3

allocated among such employees.  Allocations of any bonus amounts to Mr. Barry E. Davis under the Transaction Bonus Plan will be made by the compensation committee of the Partnership Board, and allocations to the other named executive officers will be subject to the review and approval of the compensation committee of the Partnership Board and the Partnership Board.
