The aggregate purchase price of the 326,654 Shares held in the Starboard Value LP Accounts is approximately $21,231,489, excluding brokerage commissions.

Item 4.

Purpose of Transaction.

The Reporting Persons purchased the Shares based on the Reporting Persons’ belief that the Shares, when purchased, were substantially undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

The Reporting Persons believe there is a substantial opportunity to improve the Issuer’s operating margins given the large disparity in the Issuer’s margins versus its best-in class peers. Based on recent press reports, the Reporting Persons understand that the Issuer may be working with investment bankers to explore a sale of the Issuer. The Reporting Persons believe that if the Issuer runs a legitimate, robust process to explore strategic alternatives, there would be significant strategic and financial buyer interest in such sale process.

Starboard Value LP has retained D. Jamie Macdonald to consult with the Reporting Persons regarding the pharmaceutical and healthcare services industries, including the Issuer. Mr. Macdonald has substantial experience as an industry executive, including as CEO of INC Research and SVP and Head of Global Project Management of Quintiles, where he helped to significantly improve operating margins. Starboard Value LP entered into an Advisor Agreement with Mr. Macdonald defined and described in Item 6 below.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis.
