Adopting Employers are listed on Schedule 1." 2. Section 1.1(w) of the Plan is hereby amended by deleting such section in its entirety and substituting the following: "(w) Executive: Any person who, on or after the Effective Date, is classified as an executive officer of the Company covered by a bonus arrangement and who is receiving remuneration for personal services rendered to the Company (or would be receiving such remuneration except for an Authorized Leave of Absence), and any other officer of the Company (or an Adopting Employer) designated by the Chief Executive Officer of the Company as eligible to participate in the Plan and who is listed on an Appendix attached hereto." 3.

This Plan shall create only a contractual obligation on the part of the Obligated Employer and Participants shall have the status of general unsecured creditors of the Obligated Employer under the Plan with respect to amounts of Compensation they defer hereunder or any other obligation of the Obligated Employer to pay benefits pursuant hereto. Any funds of the Obligated Employer available to pay benefits pursuant to the Plan shall be subject to the claims of general creditors of the Obligated Employer, and may be used for any purpose by the Obligated Employer. Notwithstanding the preceding paragraph, the Obligated Employer may at any time transfer assets to a trust for purposes of paying all or any part of its obligations under this Plan. However, to the extent provided in the trust only, such transferred amounts shall remain subject to the claims of general creditors of the Obligated Employer. To the extent that assets are held in a trust when a Participant's benefits under the Plan become payable, the Plan Administrator shall direct the trustee to pay such benefits to the Participant from the assets of the trust." 5. Article XII of the Plan is hereby amended by adding the following new section 12.8: "12.8 Guarantee of Performance: In consideration of each Participant's performance of valuable services that inure to the financial benefit of the Company, the Company does hereby agree to perform all of the obligations and responsibilities and pay any benefits due and owing to a Participant under the Plan if the Obligated Employer (as defined in Article X) designated to perform such obligations and responsibilities or pay such benefits fails or is unable to do so." 6. The Plan is hereby amended by incorporating the following as Schedule 1: "Schedule 1 Adopting Employers North Bros, Inc. National Service Industries, Inc. of Georgia NSI Enterprises, Inc.
