Common Stock accepted for payment pursuant to the Offer, the Shares for a
purchase price per share of $9.50 in cash or such greater amount as shall be

at least two business days prior to the Closing Date), of immediately
available funds in an amount equal to the product of the number of Shares

Section 1.04. Proxy. (a) Effective upon such time as Purchaser
------
accepts for payment and pays for, pursuant to the Offer and prior to Closing,
any shares of Company Common Stock pursuant to the Offer, Seller hereby
irrevocably grants to, and appoints, Purchaser and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, or either of
them, and any individual designated in writing by either of them, and each of
them individually, as Seller's proxy and attorney-in-fact (with full power of
substitution), for and in the name, place and stead of Seller, to vote the
Shares or grant a consent or approval in respect of the Shares on any matter in
such proxy's sole discretion. Seller hereby further affirms that such
irrevocable proxy is coupled with an interest and may under no circumstances be
revoked. Seller hereby ratifies and confirms all that such irrevocable proxy
may lawfully do or cause to be done by virtue hereof. Such irrevocable proxy is
executed and intended to be irrevocable in accordance with the provisions of
Section 212(e) of the DGCL.
(b) Seller agrees not to (i) sell, transfer, pledge, assign or
otherwise dispose of (including by gift) (collectively, "Transfer"), or enter

SECTION 1.05. Representations and Warranties of Seller. Seller hereby
