thereof (collectively, the “Transaction

Affiliate hereby agrees not to offer, sell, contract to sell, assign, transfer,
hypothecate, gift, pledge or grant a security interest in, or otherwise dispose
of, or enter into any transaction which is designed to, or might reasonably be

donees thereof agree to be bound in writing by the restrictions set forth
herein, (ii) to any trust for the direct or indirect benefit of the undersigned

subsidiary agrees to be bound in writing by the restrictions set forth herein,
and provided further that any such transfer shall not involve a disposition for
value, or (B) the acquisition or exercise of any stock option issued pursuant to
the Company’s stock option plans, including any exercise effected by the

rights, title or otherwise may be transferred to and inure to the benefit of the
Purchasers.

Agent. The Company is hereby authorized and required to disclose the

agent are hereby authorized and required to decline to make any transfer of the
Common Stock if such transfer would constitute a violation or breach of this

Agreement.
