to as the "Prior Form S-8s", are incorporated herein by reference. Unless
otherwise specified, capitalized terms herein shall have the meanings ascribed
to them in the Prior Form S-8s.

         On June 5, 2006, the Registrant's stockholders approved the amendment
and restatement of the 1997 Stock Plan. As amended and restated, the 1997 Stock
Plan provides that the maximum aggregate number of shares with respect to which
awards may be made under the 1997 Stock Plan after the effective date of the
amendment and restatement is the sum of (a) 2,300,000 shares, plus (b) any
shares returned (or that would have otherwise returned) to the 1997 Stock Plan
on or after the date of approval by the Registrant's Board of Directors (the
"Board") of the amendment and restatement of the 1997 Stock Plan as a result of
termination of options or repurchase of shares issued under such plan prior to
the date of the Board's approval of the amendment and restatement of the 1997
Stock Plan, plus (c) any shares returned (or that would have otherwise returned)
to the Registrant's 1998 Director Option Plan on or after the date of the
Board's approval of the amendment and restatement of the 1997 Stock Plan as a
result of termination of options or repurchase of shares issued under such plan.

         At the time of the approval of the 1997 Stock Plan by the Registrant's
stockholders, there were 1,582,289 shares of the Registrant's Common Stock that
had been previously registered under the Prior Form S-8s and that were available
for issuance under the 1997 Stock Plan. The Registrant is registering an
additional 717,711 shares (the difference between the 2,300,000 share number set
forth in the amended and restated 1997 Stock Plan and the 1,582,289 previously
registered and available shares at the effective date of the amended and
restated 1997 Stock Plan) of its Common Stock under this Registration Statement
all of which are reserved for issuance under the Registrant's 1997 Stock Plan.
Under the Prior Form S-8s, the Registrant previously registered an aggregate of
10,169,952 shares of its Common Stock for issuance under the 1997 Stock Plan.

         On June 5, 2006, the Registrant's stockholders approved the amendment
and restatement of the 1997 Stock Plan. As amended and restated, the 1997 Stock
Plan provides that the maximum aggregate number of shares with respect to which
awards may be made under the 1997 Stock Plan after the effective date of the
amendment and restatement is the sum of (a) 2,300,000 shares, plus (b) any
shares returned (or that would have otherwise returned) to the 1997 Stock Plan
on or after the date of approval by the Registrant's Board of Directors (the
"Board") of the amendment and restatement of the 1997 Stock Plan as a result of
termination of options or repurchase of shares issued under such plan prior to
the date of the Board's approval of the amendment and restatement of the 1997
Stock Plan, plus (c) any shares returned (or that would have otherwise returned)
to the Registrant's 1998 Director Option Plan on or after the date of the
Board's approval of the amendment and restatement of the 1997 Stock Plan as a
result of termination of options or repurchase of shares issued under such plan.

         At the time of the approval of the 1997 Stock Plan by the Registrant's
stockholders, there were 1,582,289 shares of the Registrant's Common Stock that
had been previously registered under the Prior Form S-8s and that were available
for issuance under the 1997 Stock Plan. The Registrant is registering an
additional 717,711 shares (the difference between the 2,300,000 share number set
forth in the amended and restated 1997 Stock Plan and the 1,582,289 previously
registered and available shares at the effective date of the amended and
restated 1997 Stock Plan) of its Common Stock under this Registration Statement
all of which are reserved for issuance under the Registrant's 1997 Stock Plan.
Under the Prior Form S-8s, the Registrant previously registered an aggregate of
10,169,952 shares of its Common Stock for issuance under the 1997 Stock Plan.
