Exchange Act of 1934; or (x) any action similar to any of those enumerated
above.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

     (a) The Reporting Person beneficially owns 3,588,139 shares of common stock

directors nominated by Cascade. The Voting Letter Agreement shall terminate on
the earlier of the date that Cascade and its affliates own less than 10% of the
Issuer's securities and the date the Reporting Person is not an officer,
director or employee of the Issuer or its subsidiaries.

LOCK-UP AGREEMENT

In connection with the issuance of the Series A Preferred Stock, Reporting
Person, certain other stockholders of Issuer (each a "Stockholder"), the Issuer
and Cascade entered into a Lock-Up Agreement (the "Lock-Up Agreement"). The
