Deferred Share Agreement, dated May 20, 2008



 Exhibit 10(hh) 
 DEFERRED SHARE AGREEMENT 
 This Deferred Share Agreement, dated as of
May 20, 2008 (this “Agreement”) by and among Energy Future Holdings Corp. (“Parent”) and David A. Campbell (the “Executive”). 

WHEREAS, the Executive is employed by Parent and Luminant Holding Company LLC (“Luminant”), a subsidiary of Parent,
pursuant to an employment agreement dated May 9, 2008 (the “Employment Agreement”); 
 WHEREAS, in
connection with Executive’s continued employment with Parent and Luminant, Parent has agreed to deliver 500,000 shares of common stock, no par value, of Parent (“Shares”) on the Distribution Date, as defined below; 

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in
this Agreement, and intending to be legally bound hereby, the parties hereto agree as follows: 
 ARTICLE I

 DEFERRED SHARE AWARD 
 1.1 Number of Shares. Parent shall deliver 500,000 Shares to the Executive on the Distribution Date; provided, however, that if, after the date hereof and prior to the Distribution Date, there is a
merger, spin-off, stock dividend, recapitalization, reorganization, stock split or other similar event that results in an adjustment to an outstanding Share, the number of Shares to be delivered on the Distribution Date pursuant to Section 1.1
shall be adjusted by the Board of Directors of Parent (or a committee thereof) in a manner which is necessary to reflect the effect of such event on the Shares, consistent with the treatment of stockholders of Parent. 

1.2 Distribution Date. 
 (a) The Shares shall be delivered to the Executive on the “Distribution Date”, which, subject to Section 3.3 below, shall be the earlier of the following dates: 

(1) the occurrence of Executive’s separation of service for any reason, or, if necessary to meet the distribution requirement of
Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), the date that is six months and one day following such separation; and 
 (2) the later of January 2, 2009 or the occurrence of a change in the ownership or effective control of Parent, or in the ownership of a substantial portion of the assets of Parent; 

in each case within the meaning of, and interpreted in a manner consistent with regulations under, Section 409A of the Code. 







 (b) In the event of the Executive’s death, any distribution to which the Executive
would be entitled shall be made to the Executive’s estate or in accordance with the Executive’s will, the designated beneficiary. 
 1.3 Dividends. If there is any dividend or distribution in respect of outstanding Shares, the Executive shall be entitled to receive a payment in respect of the Shares in the amount and form, and
at the time, that such payment would have been made had the Executive actually held the underlying Shares, subject to applicable withholding taxes. 
 1.4 Right to Diversify. If, prior to the Distribution Date, any of the Shares, had they been delivered to the Executive, would be released from the transfer restrictions contained in the Management
Stockholders Agreement and could have been sold by the Executive without violation of applicable law or Parent’s trading policy, then upon and following the time of such release, the Executive shall have the right (a “Diversification
Right”), exercisable by written notice to Parent and subject to reasonable administrative limitations, to convert his right to receive any or all of the Shares on the Distribution Date into a right to receive cash on the Distribution Date.
In addition, the Executive shall have a Diversification Right with respect to any Shares that he would have been permitted to sell under the Sale Participation Agreement had he actually owned the Shares. In the event the Executive exercises a
Diversification Right with respect to any Shares, the cash to be delivered to him on the Distribution Date shall equal the Fair Market Value (as defined in the Management Stockholders Agreement) of the Shares as to which the Diversification Right
was exercised on the date of such exercise, as subsequently credited with investment returns based on notional investments as selected by the Executive from time to time following exercise of the Diversification Right from among those that Parent
shall make available from among those notional investments under any nonqualified deferred compensation plan then maintained by Parent (or, if no such notional investments are made available, with compound annual interest equal to the prevailing
prime rate plus 2 percentage points, but in no event shall it exceed Parent’s borrowing rate). 
 ARTICLE II

 ADDITIONAL AGREEMENTS 
 2.1 Additional Agreements. Simultaneously with the execution of this Agreement, the parties shall execute a Management Stockholders Agreement and a Sale Participation Agreement each of which shall
apply to the Shares subject to this Agreement 
 2.2 Special Put Right. If the Executive’s employment with Parent
and Luminant terminates for any reason prior to January 31, 2009, other than for Cause (as defined in the Employment Agreement), he shall have the right (but not the obligation) to sell to Parent all (but not less than all) of the Shares
delivered pursuant to Section 1.2 for a purchase price of $2,500,000 (the “Special Put Right”). In the event the Executive intends to exercise the Special Put Right, he shall send written notice, postmarked on or prior to the
sixtieth day following termination of his employment, to Parent of his intention to sell the Shares in exchange for the applicable purchase price (“Put Option Notice”). The completion of the purchase shall take place at the
principal office of Parent no later than the twentieth business day (such date to be determined by Parent) after the giving of the Put Option Notice. The applicable purchase price shall be paid by delivery to the Executive of a check payable to the
order of the Executive against delivery of duly executed stock powers transferring the Shares.

 ARTICLE III 

TAX MATTERS 
 3.1 Tax Withholding and Reporting. Upon any Distribution Date, Parent shall be entitled to withhold from any payment or distribution to the Executive an amount necessary to satisfy applicable
withholding taxes that become due by reason of such payment or distribution. Parent acknowledges that for income tax purposes, the Executive will not include into income any amount payable on the Distribution Date until payment is actually made on
the Distribution Date. Parent shall report and file all Parent tax returns and information reports (including Form W-2) consistent with such position. 
 3.2 Delivery Before Liquidity. If, on the Distribution Date, (i) Shares are to be delivered to the Executive, and (ii) the Executive cannot resell promptly within a reasonable time
thereafter such Shares either because there is no public market for the Shares, or the Executive is restricted under the Management Stockholders Agreement, Parent trading policies or applicable securities law from selling the Shares, Parent shall,
immediately repurchase such number of Shares that, on the Distribution Date, have a Fair Market Value equal to the minimum statutory tax withholding obligation attributable to delivery of the Shares. 

3.3 Tax Assessment Prior to Distribution Date. If there is a final tax assessment against the Executive that any amount otherwise
payable under this Agreement is taxable in a year prior to the year that includes the Distribution Date, Parent shall immediately pay or distribute the cash or Shares that otherwise would have been paid or delivered on the Distribution Date, and if
the Executive cannot promptly within a reasonable time thereafter resell such Shares either because there is no public market for the Shares, or the Executive is restricted under the Management Stockholders Agreement, Parent trading policies or
applicable securities law from selling the Shares, Parent shall immediately repurchase such number of Shares that, on the Distribution Date, have a Fair Market Value equal to the amount of such tax assessment (or, if such assessment exceeds the Fair
Market Value of all of the Shares, then all of the Shares will be repurchased). 
 ARTICLE IV
