The registration rights granted to certain of the Selling Stockholders
generally provide that the Company and the Selling Stockholders indemnify each
other against certain liabilities, including liabilities under the Securities
Act. In the opinion of the Commission, such indemnification is against public
policy and is, therefore unenforceable.
