exercise of the Repurchase Option pursuant to subsection (a) above, the Escrow
Holder shall tender to the Company at its principal offices the certificate or
certificates representing the Shares which the Company has elected to purchase,
duly endorsed in blank by the Employee or with duly endorsed stock powers
attached thereto, all in form suitable for the transfer of such Shares to the
Company. Upon its receipt of such certificate or certificates, the Company shall

Repurchase Price therefor.

the Company for transfer to the Company pursuant to subsection (b) above, the

with respect to such Shares, but shall, insofar as permitted by law, treat the
Company as the owner of such Shares.

in cancellation of all or a portion of any outstanding indebtedness of the
Employee to the Company or in cash (by check) or both.

(b) Notwithstanding the foregoing, the Employee may transfer Shares to
or for the benefit of any spouse, child, or grandchild, or to a trust for the
benefit, provided that any Unvested Shares shall remain subject to this
Agreement (including without limitation the restrictions on transfer set forth
in this Section 5 and the Repurchase Option), and such permitted transferee
shall, as a condition to such transfer, deliver to the Company a written
instrument

confirming that such transferee shall be bound by all of the terms and
conditions of this Agreement.

5.7 Effect of Prohibited Transfer. The Company shall not be required (a)
to transfer on its books any of the Shares which shall have been sold or
transferred in violation of any of the provisions set forth in this Agreement,
or (b) to treat as owner of such Shares or to pay dividends to any transferee to
whom any such Shares shall have been so sold or transferred.

Shares shall have affixed thereto a legend in substantially the following form,
