Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On September 29, 2014, Engaged Capital delivered an open letter (the “Letter”) to the Board of Directors of the Issuer (the “Board”). The Letter detailed a myriad of strategic, operational, communication and financial failures under the current Board and management team, which have resulted in the continued underperformance of the Issuer and material destruction of shareholder value. Among the Issuer’s continued missteps, Engaged Capital cited the Issuer’s bloated expense structure, value-destructive capital allocation, flailing corporate strategy, wildly inconsistent investor communications and excessive executive compensation.

Accordingly, Engaged Capital concluded the current Board and management team are no longer the appropriate custodians of the Issuer’s assets. Engaged Capital insisted that the Board immediately add shareholder representatives and begin a parallel process to evaluate strategic alternatives and conduct a CEO search for candidates with a history of driving profitability and extracting value from medical device assets in the event the Issuer remains an independent company.

The foregoing description of the Letter is qualified in its entirety by reference to the full text of the Letter, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.
