REPORTS OF THE REPORTING PERSONS, ITEM 4 (PURPOSE OF TRANSACTION) AND ITEM 5

Item 4.     Purpose of Transaction

	As of June 11, 2012, ValueAct SmallCap Master Fund, the direct owner
of 6,322,187 shares of Common Stock, has undertaken to distribute in kind
such shares to its investors. A total of 55,935 of these shares was held

transferred to ValueAct SmallCap Master fund for no consideration in
connection with the in kind distribution.  Settlement of this in-kind
distribution may occur on or after the date hereof.  The ValueAct SmallCap
Reporting Persons do not intend to make further purchases of Common Stock.

     In pursuing their investment purposes, the ValueAct Master Fund
Reporting Persons may further purchase, hold, vote, trade, dispose or
otherwise deal in the Common Stock at times, and in such manner, as they deem
advisable to benefit from changes in market prices of such Common Stock,
changes in the Issuer's operations, business strategy or prospects, or from
sale or merger of the Issuer.  To evaluate such alternatives, the ValueAct
Master Fund Reporting Persons will routinely monitor the Issuer's operations,
prospects, business development, management, competitive and strategic
matters, capital structure, and prevailing market conditions, as well as
alternative investment opportunities, liquidity requirements of the ValueAct
Master Fund Reporting Persons and other investment considerations.
Consistent with its investment research methods and evaluation criteria, the
ValueAct Master Fund Reporting Persons may discuss such matters with
management or directors of the Issuer, other shareholders, industry analysts,
existing or potential strategic partners or competitors, investment and
financing professionals, sources of credit and other investors.  Such factors
and discussions may materially affect, and result in, the ValueAct Master
Fund Reporting Persons ' modifying their ownership of Common Stock, exchanging
information with the Issuer pursuant to appropriate confidentiality or
similar agreements, proposing changes in the Issuer's operations, governance
or capitalization, or in proposing one or more of the other actions described
in subsections (a) through (j) of Item 4 of Schedule 13D.

      The Reporting Persons reserve the right to formulate other plans and/or
make other proposals, and take such actions with respect to their investment
in the Issuer, including any or all of the actions set forth in paragraphs
(a) through (j) of Item 4 of Schedule 13D, or acquire additional Common Stock
or dispose of all the Common Stock beneficially owned by them, in the public
