If the termination is by reason of the death or Permanent Disability of the Executive, the Executive also shall be entitled to receive his annual bonus prorated through the Date of Termination (offset by any proceeds received from any insurance coverages provided by the Company or any of its affiliates). For such purposes, the annual bonus shall not be less than the average annual bonus received for the preceding three years (if Executive has not yet received bonuses for three years, he shall receive a prorated portion of the average of the bonuses received, if any, but not less than a prorated portion of 90% of his Base Salary).

Any copyrightable <Page> -8- work prepared in whole or in part by the Executive during the Employment Period will be deemed "a work made for hire" under Section 201(b) of the Copyright Act of 1976, as amended, and the Company will own all of the rights comprised in the copyright therein. The Executive will promptly and fully disclose all Intellectual Property and will cooperate with the Company to protect the Company's interests in and rights to such Intellectual Property (including providing reasonable assistance in securing patent protection and copyright registrations and executing all documents as reasonably requested by the Company, whether such requests occur prior to or after termination of Executive's employment hereunder).

ARTICLE 9 NONCOMPETITION AND NONSOLICITATION SECTION 9.01. NONCOMPETITION. The Executive acknowledges that during his employment with the Company, he will become familiar with trade secrets and other Confidential Information concerning the Company, its Subsidiaries and their respective predecessors, and that his services will be of special, unique and extraordinary value to the Company.

Notwithstanding the foregoing, if such termination is by the Company without Cause or by the Executive for Good Reason, the Noncompetition Period shall extend for the period during which severance is paid under Section 5.02. If such termination is due to the Company or the Executive giving written notice pursuant to Section 5.01 of their intention not <Page> -9- to extend the Employment Period, the Noncompetition Period shall be for a period of up to twenty four (24) months following the date of termination if the Company elects in writing to pay the Executive the sum of Base Salary and target annual bonus set forth in Section 4.02 for such period, such amount to be payable in monthly installments over such period.
