                           (ii)  The covenants and agreements of the Executive
         contained in Sections 5, 6 and 7 shall survive termination of the

         which shall be paid as soon as practicable after the end of such fiscal
         period, but not later than sixty (60) days thereafter, and except for
         payments pursuant to Section 4(h).

         5. Confidentiality and Non-Disclosure. Executive recognizes that he
will occupy a position of trust with respect to the Company and agrees to use
all Confidential Information solely in connection with the performance of
services for or on behalf of the Company. Executive shall not, during the term
of this Agreement, or at any time after the termination of this Agreement, in
any manner, either directly or indirectly, (i) disseminate, disclose, use or
communicate any Confidential Information to any person or entity, regardless of
whether such Confidential Information is considered to be confidential by third
parties, or (ii) otherwise directly or indirectly misuse any Confidential
Information; provided, however, that (y) none of the provisions of this Section
5 shall apply to disclosures made for valid business purposes of the Company.

         Executive hereby acknowledges and agrees that all personal property and
equipment, relating to the business of the Company, including, without
limitation, all books, manuals, records, reports, notes, contracts, lists,
blueprints, and other documents or materials, or copies thereof (including
computer files), and all other proprietary information relating to the business
of the Company, furnished to or prepared by Executive in the course of or
incident to Executive's employment, belongs to the Company and shall be promptly
returned to the Company within three (3) days after the Termination Date.
Following the Termination Date, Executive will not retain any written or other
tangible material containing any proprietary information of the Company.

         6. Non-Solicitation. Executive hereby covenants and agrees that, during
the term of this Agreement and for a period of one (1) year thereafter,

interfere with the contractual relationship

between the Company and any of its vendors or suppliers or (ii) employ or
solicit for employment any officer or key employee who is employed by the
Company.

         7. Enforcement. It is understood and agreed by the parties that no
amount of money would adequately compensate the Company for damages which the
parties acknowledge would be suffered as a result of a violation by the
Executive of the covenants contained in Sections 5 and 6 above, and that,
therefore, the Company shall be entitled, upon application to a court of
competent jurisdiction, to obtain injunctive relief (without the need to post
bond) to enforce the provisions of Sections 5 and 6, which injunctive relief
shall be in addition to any other rights or remedies available to the Company.

to require performance of any provision hereof in no manner shall affect the
right at a later time to enforce the same. No waiver by either party of a breach
of any term or covenant contained in this Agreement, whether by conduct or
otherwise, in any one or more instances, shall be deemed to be or construed as a
further or continuing waiver of any such breach or waiver of any other term or
