-9-

(b) The existence of the Plan and the Stock Incentives granted hereunder shall not affect in any way the right or power of the Board or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of debt or equity securities having any priority or preference with respect to or affecting Common Stock or the rights thereof, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or any other corporate act or proceeding.

(c) The shares with respect to which Stock Incentives may be granted are shares of Common Stock as presently constituted, but, after the Effective Date if, and whenever, prior to the expiration of a Stock Incentive, the Company shall effect a subdivision or consolidation of shares of Common Stock or the payment of a stock dividend on Common Stock without receipt of consideration by the Company, the number of shares of Common Stock with respect to which such Stock Incentive relates or may thereafter be exercised (i) in the event of an increase in the number of outstanding shares shall be proportionately increased, and, as applicable, the purchase price per share shall be proportionately reduced, and (ii) in the event of a reduction in the number of outstanding shares shall be proportionately reduced, and, as applicable, the purchase price per share shall be proportionately increased.

(e) In the event of a Corporate Change, unless an instrument granting the Stock Incentive otherwise provides, as of the Corporate Change Effective Date (i) any outstanding Options shall become immediately vested and fully exercisable or (ii) any restrictions on Restricted Stock Awards shall immediately lapse. A Corporate Change shall be determined solely by reference to the terms of this Plan and shall not be determined by reference to the terms of the Halliburton Plan for any purpose with respect to the Stock Incentives.

(g) Except as hereinbefore expressly provided, the issuance by the Company of shares of stock of any class or securities convertible into shares of stock of any class, for cash, property, labor or services, upon direct sale, upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, and in any case whether or not for fair value, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Common Stock subject to Stock Incentives theretofore granted or the purchase price per share of Common Stock subject to Options.

ARTICLE IX

AMENDMENT OF PLAN

ARTICLE X

MISCELLANEOUS PROVISIONS

10.1 No Right To An Award.

Neither the adoption of the Plan nor any action of the Board or of the Committee shall be deemed to give an employee or a Director any right to be granted a Stock Incentive or any other rights hereunder except as may be evidenced by the document providing for such Stock Incentive, and then only to the extent of and on the terms and conditions expressly set forth therein. The Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of funds or assets to assure the payment of any Stock Incentive.

10.2 Other Laws; Withholding.

The Company shall not be obligated to issue any Common Stock pursuant to any Stock Incentive granted under the Plan at any time when the offering of the shares covered by such Stock Incentive has not been registered under the Securities Act of 1933, such other state and federal laws, rules or regulations, and non-U.S. laws, rules, or regulations as the Company or the Committee deems applicable and, in the opinion of legal counsel for the Company, there is no exemption from the registration requirements of such laws, rules or regulations available for the issuance and sale of such shares. The Company shall have the right to deduct in connection with all Awards any taxes required by law to be withheld and to require any payments necessary to enable it to satisfy its withholding obligations. The Committee may permit a Participant to elect to surrender, or authorize the Company to withhold, shares of Common Stock (valued at their Fair Market Value on the date of surrender or withholding of such shares) in satisfaction of the Company’s withholding obligation, subject to such restrictions as the Committee deems appropriate.

10.3 No Restriction on Corporate Action.

Nothing contained in the Plan shall be construed to prevent the Company or any Subsidiary from taking any corporate action which is deemed by the Company or such Subsidiary to be appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any Stock Incentive made under the Plan. No Participant, beneficiary or other person shall have any claim against the Company or any Subsidiary as a result of any such action.

10.4 Restrictions on Transfer.

Except as otherwise provided herein, a Stock Incentive shall not be sold, transferred, pledged, assigned or otherwise alienated or hypothecated by a Participant other than by will or the laws of descent and distribution or pursuant to a “qualified domestic relations order” as defined by the Code or Title I of the Employee Retirement Income Security Act of 1974, as amended, and shall be exercisable during the lifetime of the Participant only by such Participant, the Participant’s guardian or legal representative, a transferee under a qualified domestic relations order or a transferee as described below. The Committee may prescribe and include in the respective agreements providing for the Stock Incentive hereunder other

-12-

restrictions on transfer. Any attempted assignment or transfer in violation of this Section shall be null and void. Upon a Participant’s death, the Participant’s personal representative or other person entitled to succeed to the rights of the Participant (the “Successor”) may exercise such rights as are provided under the agreement providing for the Stock Incentive. A Successor must furnish proof satisfactory to the Company of his or her rights to exercise the Stock Incentive under the Participant’s will or under the applicable laws of descent and distribution. Notwithstanding the foregoing, the Committee shall have the authority, in its discretion, to permit the transfer of a Stock Incentive by the Participant for no consideration to or for the benefit of the Participant’s Immediate Family, to a trust solely for the benefit of the Participant and his Immediate Family, or to a partnership or limited liability company in which the Participant and members of his or her Immediate Family have at least 99% of the equity, profit and loss interest. A transfer of a Stock Incentive pursuant to this Section shall be subject to such rules and procedures as the Committee may establish. In the event a Stock Incentive is transferred as contemplated in this Section, such Stock Incentive may not be subsequently transferred by the transferee except by will or the laws of descent and distribution, and such Stock Incentive shall continue to be governed by and subject to the terms and limitations of the Plan and the relevant written instrument for the Stock Incentive and the transferee shall be entitled to the same rights as the Participant hereof as if no transfer had taken place. No transfer shall be effective unless and until written notice of such transfer is provided to the Committee, in the form and manner prescribed by the Committee. The consequences of termination of employment shall continue to be applied with respect to the original Participant, following which the Stock Incentive shall be exercised by the transferee only to the extent and for the periods specified in the Plan and the related agreement providing for the Stock Incentive.

10.5 Governing Law.

This Plan shall be construed in accordance with the laws of the State of Texas, except to the extent that it implicates matters which are the subject of the General Corporation Law of the State of Delaware which matters shall be governed by the latter law.

10.6 Section 409A.

Notwithstanding anything in this Plan to the contrary, if any Plan provision or Stock Incentive under the Plan would result in the imposition of an applicable tax under Section 409A of the Code and related regulations and Treasury pronouncements (“Section 409A”), that Plan provision or Stock Incentive will be reformed to avoid imposition of the applicable tax and no action taken to comply with Section 409A shall be deemed to adversely affect the Participant’s rights with respect to a Stock Incentive.
