The Employer and Executive shall share equally the costs of any appraisers.

8. Representations and Warranties of the Employer. The Employer hereby represents and warrants to Executive as follows:

(d) Executive further agrees in no event to make any disposition of all or any part of the Vested Shares unless and until (i) Executive shall have notified the Employer of the proposed disposition; (ii) Executive shall have received an opinion of counsel to the effect that such disposition will not require the registration or qualification of the Vested Shares under
