REPURCHASE RIGHT.

FAILURE TO MEET SALES TARGET. Within 105 days of the end of MicroTel's fiscal year, MicroTel shall give to the Remaining Employees by registered or certified mail the Gross Sales together with appropriate backup for such calculation. Upon receipt of such calculation, if the Gross Sales have failed to meet the Sales Target for the second consecutive fiscal year, the Remaining Employees shall have 45 days to give notice to MicroTel by registered or certified mail of their intent to value the Critical Line of Business (the "Appraisal Request"). Within 20 days of MicroTel's receipt of the Appraisal Request, the Remaining Employees and MicroTel shall each select an independent certified appraiser at their own cost and expense who, within 20 days of their selection, shall value the Critical Line of Business.

Thereafter, MicroTel and the Remaining Employees shall utilize reasonable best efforts to consummate the purchase of the Critical Line of Business as quickly as possible. The Remaining Employees shall be able to issue a promissory note in favor of MicroTel for 50% of the Purchase Price. Said note shall bear interest at the prime rate, be secured by the Critical Line of Business and have a maturity of not more than five years. PROPOSED SALE TO THIRD PARTY.

The notice shall identify the entity to whom the transfer is to be made together with a copy of the offer containing all of the terms and conditions, including price, of the intended disposition. The Remaining Employees, for forty-five (45) days after receipt of said notice, shall have the option to purchase the Technology or the Critical Products.
