Tai, and Michael J. Zak is a managing member of Charles River XI GP, LLC. Accordingly, each of Charles River XI GP, LP, Charles River XI GP, LLC and Messrs. Armony, Baldwin, Burnes, Dintersmith, Sachs, Tai, and Zak (collectively, the "Management Persons") may be deemed to beneficially own the securities owned by the Partnerships. Each of the Management Persons disclaims beneficial ownership of the securities reported herein held by the Partnerships, except to the extent of such person's pecuniary interest in each applicable Partnership, if any.
10. The filing of this statement by any reporting person shall not be deemed an admission that such person is, for purposes of Section 16 of the Securities Exchange Act of 1934 or otherwise, the beneficial owner of any equity securities covered by this statement.
Remarks:
Charles River Partnership XI, LP, Charles River Friends XI-A, LP, Charles River Friends XI-B, LP, Charles River XI GP, LP, and Charles River XI GP, LLC are also reporting persons. Because the SEC's filing system will not accept CIK and CCC codes from more than ten joint filers of a report, such persons filed a separate Form 3, as amended. Such other Form 3, as amended, and this amended Form 3 (collectively, the "Amended Form 3") relate to the same securities and transactions. Thus, in total, there are eleven (11) joint filers: Charles River Partnership XI, LP, Charles River Friends XI-A, LP, Charles River Friends XI-B, LP, Charles River XI GP, LP, Charles River XI GP, LLC, Izhar Armony, Christopher Baldwin, Richard M. Burns, Jr., Ted R. Dintersmith, William P. Tai, and Michael J. Zak. Bruce I. Sachs files separately with respect to BigBand Network, Inc. The Amended Form 3 amends the Form 3 filed March 14, 2007 (the "Initial Form 3"), which did not include the Management Persons as reporting persons. A Form 4 was filed on March 22, 2007 relating to the securities reported on the Initial Form 3, which also did not include the Management Persons as reporting persons.
