For purposes of this paragraph, no act, or failure to act, on the Executive's part shall be considered "willful" unless done, or omitted to be done, by the Executive not in good faith and without reasonable belief that his action or omission was in the best interest of the Company.

Therefore, during the period of his employment, except for illness, reasonable vacation periods and reasonable leaves of absence, the Executive shall devote all of his business time, attention, skill and efforts to the faithful performance of his duties under this Agreement. However, the Executive may devote a small but reasonable amount of time to pursue and monitor personal investments and charitable or community services and, with the approval of the Board, from time to time, the Executive may serve or continue to serve on the boards of directors of and hold any other offices or position in companies or organizations that in the Board's reasonable judgment will not present any Conflict of Interest with the Company or any of its Affiliates or materially affect the performance of the Executive's duties under this Agreement.

For each calendar year during the term of this Agreement the Executive shall be entitled to earn a bonus of between 0% and 90% of the Executive's Minimum Annual Salary for such year upon attaining goals established annually by the Compensation Committee. The goals shall be established by the Compensation Committee, after consultation with the Executive, shall be consistent with the Company's standards, and shall be established to produce a reasonable expectation in the sole judgment of the Compensation Committee that the Executive will receive a target bonus for each year equal to 60% of the Executive's Minimum Annual Salary for such year. Bonus factors and other provisions related to the bonus for calendar year 1997 (which will be consistent with the Executive's position in the Company and with other executives) will be addressed by the Compensation Committee at its meeting on February 11, 1997. The Cash Incentive Compensation earned by the Executive for any calendar year to the extent not deferred pursuant to Section 6.3, will be paid to the Executive within 90 days following the end of such calendar year. 6.3 DEFERRAL ARRANGEMENT. The Executive will be permitted to defer some or all of the Cash Incentive Compensation and up to 50% of the Minimum Annual Salary under the ENSERCH Corporation Deferred Compensation Plan (or comparable plan of the Company), the terms of which have been provided to the Executive. 6.4 STOCK OPTIONS. On or promptly after the Effective Date, the Company shall grant to the Executive an initial signing bonus award of Stock Options to acquire 1,000,000 shares of the common stock of the Company with an exercise price based on the average of the high and low prices on the date of grant and granted as follows: An option for 500,000 of the shares will be granted by the Compensation Committee pursuant to the Stock Incentive Plan and shall be conditioned upon the execution by the Executive of a stock option agreement substantially in the form as attached hereto as Exhibit A, and an option with substantially identical terms for the remaining 500,000 shares will be granted by the Board by special award and shall be conditioned upon the execution by the Executive of a stock option agreement substantially in the form as attached hereto as Exhibit B. Not later than sixty (60) days following each anniversary of the Effective Date during the term of this Agreement (provided the Executive continues to be employed by the Company), the Company shall grant to the Executive a Stock Option to acquire a number of additional shares of the common stock of the Company with the grant in 1998 to be calculated as follows: at least the number derived from dividing three (3) times the Executive's Minimum Annual Salary by the fair market value on the last trading date preceding the day that the Compensation Committee or Board takes action to grant the Option. Grants in subsequent years shall be made in an amount equal to 115% of the Executive's Minimum Annual Salary, in accordance with a valuation methodology selected by the Compensation Committee, after consultation with the Executive and which appropriately aligns the compensation that the Executive may receive through stock price growth with the value received by shareholders from the Company's performance. The exercise price per share under such option shall be the fair market value of the stock as of the date of the grant of such option. The Options granted to the Executive during the term of this Agreement beyond the initial grant shall be Non-Qualified Stock Options and shall be pursuant to, and conditioned upon the execution by the Executive of, stock option agreements with terms and conditions consistent with those between the Company's other senior executives and the Company and substantially in the form as attached hereto as Exhibit C. No Stock Options shall be granted subsequent to termination of employment. The Company shall use its best efforts to cause a registration statement on form S-8 (or comparable successor form) covering all shares subject to Stock Options granted to the Executive to remain effective until sixty (60) days after the later of exercise or termination of all Stock Options granted to the Executive. 6.5 RESTRICTED STOCK BONUSES. On or promptly after the Effective Date, the Company shall award to the Executive an initial Restricted Stock Bonus for 100,000 shares of performance-based restricted stock of the Company pursuant to its Stock Incentive Plan and conditioned upon the execution by the Executive of a Restricted Stock Agreement substantially in the form attached hereto as Exhibit D. Not later than sixty (60) days following each anniversary of the Effective Date during the term of this Agreement (provided the Executive continues to be employed by the Company), the Company shall award to the Executive a Restricted Stock Bonus for additional shares of performance-based restricted stock of the Company having a value equal to 35% of the Executive's Minimum Annual Salary (with performance requirements as determined by the Compensation Committee that may vary from the initial award but that are consistent with performance requirements for awards of performance-based restricted stock to other senior executives of the Company). Such shares shall be restricted so that no share may be transferred or alienated in any way (except through passage under will or by the laws of descent and distribution upon the Executive's death) until the shares are vested, at which time the restriction will lapse with respect to the vested shares. Such awards shall be granted pursuant to, and conditioned upon, execution by the Executive of restricted stock agreements with terms and conditions consistent with those of other senior executives of the Company and substantially in the form attached hereto as Exhibit E. No Restricted Stock Bonuses shall be granted subsequent to termination of employment. The Company shall use its best efforts to cause a registration statement on form S-8 (or comparable successor form) covering all shares of restricted stock granted to the Executive as Restricted Stock Bonuses to remain effective until sixty (60) days after the lapse of all restrictions on the shares of restricted stock granted to the Executive as Restricted Stock Bonuses. 6.6 LONG TERM INCENTIVE AWARDS.

Within 30 days following the date that the Executive (i) makes a Section 83(b) election with respect to any Restricted Stock Bonus received by the Executive or (ii) such Restricted Stock Bonus becomes fully vested, upon request by the Executive the Company will lend the Executive an amount equal to the estimated federal, state and local tax liability the Executive will incur in connection with making a Section 83(b) election or becoming fully vested in any Restricted Stock Bonus. The loan will be on a full recourse basis and secured in accordance with the terms of a security agreement (in a form mutually agreed upon by the Executive and Company) collateralized with Restricted Stock Bonuses, Stock Options to acquire Company stock, deferred compensation and other amounts owing but unpaid by the Company to the Executive. The loan will bear interest at the prime rate in effect at that time at the Chase Manhattan Bank or other comparable bank as approved by the Compensation Committee.
