Footnotes (6)

[F1]Pursuant to a reclassification exempt under Rule 16b-7, each share of Class A and B Common Stock and Preferred Stock converted, immediately and automatically, into shares of Common Stock, as part of a recapitalization of the issuer's capital stock structure.
[F2]As of the date original filed, 50% of these shares vested. The remainder of these shares vested and will vest 25% on each of the following dates: October 31, 2010 and October 31, 2011.
[F3]Pursuant to the reclassification discussed in footnote (1), these options now convert to Common Stock instead of Class B Common Stock, only if and when exercised.
[F4]The Convertible Preferred Stock is immediately exercisable and does not have an expiration date.
[F5]These shares were sold in connection with the exercise of an over-allotment option under Rules 16a-7 and Rule 424(b)(4); they were erroneously omitted on Form 4 filed on April 29, 2010, as well as on Form 4A filed on January 11, 2011.
[F6]This note is to clarify two inconsistencies related to the Stephen Allen Skerl Grandchild Trust: (1) on Form 4 filed on April 29, 2010, this Trust was mistakenly named <<Matthew Phillip Skerl Grandchild Trust, Damir S. Skerl, Trustee>>; and (2) on Form 4A filed on January 11, 2011, this Trust was erroneously omitted.
