9.

Clause (iv) of Section 4(a) of the Original Agreement is hereby amended and restated in its entirety to provide as follows:

     (iv) With respect to all options to purchase Common Stock held by the Executive pursuant to an NOI stock option plan on or prior to the Date of Termination that were vested on or before December 31, 2004, irrespective of whether such options are then exercisable, the Executive shall have the right, during the sixty (60) day period after the Date of Termination, to elect to surrender all or part of such options in exchange for a cash payment by the Company to the Executive in an amount equal to the number of shares of Common Stock subject to the Executive’s option multiplied by the difference between (x) and (y) where (x) equals the purchase price per share covered by the option and (y) equals the highest reported sale price of a share of Common Stock in any transaction reported on the New York Stock Exchange during the sixty (60) day period prior to and including the Executive’s Date of Termination. Such cash payments shall be made within thirty (30) days after the date of the Executive’s election; provided, however, that if the Executive’s Date of Termination is within six months after the date of grant of a particular option held by the Executive and the Executive is subject to Section 16(b) of the Securities Exchange Act of 1934, as amended, any cash payments related thereto shall be made on the date which is six months and one day after the date of grant of such option to the extent necessary to prevent the imposition of the disgorgement provisions under Section 16(b).

     Any options outstanding as of the Date of Termination and not then exercisable shall become fully exercisable as of the Executive’s Date of Termination, and to the extent the Executive does not elect to surrender any options that were vested on or before December 31, 2004 for a cash payment as provided above, such options shall remain exercisable for one year after the Executive’s Date of Termination, until the stated expiration of the stated term thereof, or until the 10^th anniversary of the original date of grant thereof, whichever is shorter; any restrictions imposed by NOI or the Company that are applicable to any shares of Common Stock granted to the Executive by NOI or the Company shall lapse, as of the date of the Executive’s Date of Termination;

A new Paragraph (g) shall be added immediately following Paragraph (f) of Section 11 of the Original Agreement to provide as follows:

     (g) This Agreement is intended to meet the requirements of Section 409A of the Code and shall be administered in a manner that is intended to meet those requirements and shall be construed and interpreted in accordance with such intent. To the extent that a payment, or the settlement or deferral thereof, is subject to Section 409A of the Code, except as the Board of Directors and Executive otherwise determine in writing, the payment shall be paid, settled or deferred in a manner that will meet the requirements of Section 409A of the Code, including regulations or other guidance issued with respect thereto, such that the payment, settlement or deferral shall not be subject to the additional tax or interest applicable under Section 409A of the Code. Any provision of this Agreement that would cause the payment, settlement or deferral thereof to fail to satisfy Section 409A of the Code shall be amended (in a manner that as closely as practicable achieves the original intent of this Agreement) to comply with Section 409A of the Code on a timely basis, which may be made on a retroactive basis, if permitted under the regulations and other guidance issued under Section 409A of the Code. In the event additional regulations or other guidance is issued under Section 409A of the Code or a court of competent jurisdiction provides additional authority concerning the application of Section 409A with respect to the payments described hereunder, then the

provisions regarding such payments shall be amended to permit such payments to be made at the earliest time allowed under such additional regulations, guidance or authority that is practicable and achieves the original intent of this Agreement.

Certain capitalized terms used herein that are not otherwise defined are defined in the Original Agreement, and the terms defined in this First Amendment shall be incorporated in the Original Agreement with the same meanings as set forth herein.

19.

The validity, interpretation, construction and enforceability of this First Amendment shall be governed by the laws of the State of Texas, without reference to principles of conflict of laws.

20.

Except as amended by this First Amendment, the Original Agreement shall remain in full force and effect.

21.

This First Amendment may be executed in one or more counterparts, and by the parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which shall constitute one and the same agreement.
