Such opportunities should provide an increased incentive for these employees to contribute to the future success and prosperity of theCompany, thus enhancing the value of the stock for the benefit of the stockholders, and increase the ability of the Company to attract and retain individuals of exceptional skill upon whom, in large measure, its sustained progress, growth andprofitability depend. 

Pursuant to the Plan, options to purchase the Company’s Common Stock (“Options”) and StockAppreciation Rights may be granted and Restricted Stock may be awarded by the Company. Options granted under the Plan may be either incentive stock options, as defined in Section 422(b) of the Internal Revenue Code of 1986, as amended (the“Code”), or options which do not meet the requirements of said Section 422(b) of the Code, herein referred to as non-qualified stock options. 

It is intended, except as otherwise provided herein, that incentive stock options may be granted under the Plan and that such incentive stock options shall conform to the requirements of Section 422 and 424 ofthe Code and to the provisions of this Plan and shall otherwise be as determined by the Committee (as hereinafter defined) and, to the extent provided in the last sentence of Section 2 hereof, approved by the Board of Directors. The terms“subsidiaries” and “subsidiary corporation” shall have the meanings given to them by Section 424 of the Code. All section references to the Code in this Plan are intended to include any amendments or substitutionstherefor subsequent to the adoption of the Plan.

The Committee shall have full authority to grant Options and StockAppreciation Rights, and make Restricted Stock awards, to interpret the Plan and to make such rules and regulations and establish such procedures as it deems appropriate for the administration of the Plan, taking into consideration therecommendations of management. The decisions of the Committee shall be binding and conclusive for all purposes and upon all persons unless and except to the extent that the Board of Directors of the Company shall have previously directed that all orspecified types of decisions of the Committee shall be subject to approval by the Board of Directors. Notwithstanding the foregoing and anything else in the Plan to the contrary, the Committee, in its sole discretion, may delegate theCommittee’s authority and duties under the Plan to the Chairman of the Board of Directors and Chief Executive Officer of the Company, as a Board of Directors committee of one under Delaware law, or to any other committee of the Board of

Directors, under such conditions and limitations as the Board of Directors or the Committee may from time to time establish, except that only the Committeemay make any determinations regarding awards to participants who are subject to Section 16 of the Exchange Act. 

**Section 3. Numberof Shares****.** The total number of shares which may be sold or awarded under the Plan and with respect to which Stock Appreciation Rights may be exercised shall not exceed 65,000,000 shares of the Company’s Common Stock.

Shares with respect to which Options or Stock Appreciation Rights are not exercised prior to termination of theOption and shares that are part of a Restricted Stock award which are forfeited before the restrictions lapse shall be available for Options and Stock Appreciation Rights thereafter granted and for Restricted Stock thereafter awarded under the Plan,to the fullest extent permitted by Rule 16b-3 under the Exchange Act (if applicable at the time). 

**Section 4.

**Section 5. Terms and Conditions of Options****.** The terms and conditions of each Option and each Stock Appreciation Right shall be set forth in an agreement or agreements between the Company and theoptionee. For purposes of Section 5(a)-(g) and Section 5(i), each reference to an Option shall also be a reference to a Stock Appreciation Right.

The right todeliver in full or partial payment of such Option Price any consideration other than cash shall be limited to such frequency as the Committee shall determine in its absolute discretion.

(iii) Concurrently with the time of termination by the Company or one of itssubsidiaries of the optionee’s employment for deliberate gross misconduct, determined in the sole discretion of the Committee (for purposes only of this subparagraph (iii) an Option shall be deemed to be exercised when the optionee hasreceived the stock certificate representing the shares for which the Option was exercised); or 

(iv) Concurrently with thetime of termination by the employee of his or her employment with the Company or one of its subsidiaries for reasons other than Retirement, Disability or death.

sole discretion, allow for transfer of Options (other than incentive stock options, unless such transferability would not adversely affect incentive stockoption tax treatment) to other persons or entities, subject to such conditions or limitations as it may establish to ensure that transactions with respect to Options intended to be exempt from Section 16(b) of the Exchange Act pursuant to Rule16b-3 under the Exchange Act do not fail to maintain such exemption as a result of the Committee causing Options to be transferable, or for other purposes; providedfurther, however, that for any Option that is transferred,other than by the laws of descent and distribution, any related Stock Appreciation Right shall be extinguished. 

(i) **Applicable Laws orRegulations.** The Company’s obligation to sell and deliver stock under the Option is subject to such compliance as the Company deems necessary or advisable with federal and state laws, rules and regulations.
