       K.  O. Andreas Halvorsen, David C. Ott and Rose S. Shabet
          (a)  Amount beneficially owned: 37,231,342
          (b)  Percent of class: 61.0%
          (c)  Number of shares as to which such person has:
                  (i)    sole power to vote or to direct the vote

                         of 37,231,342

	  The percentages used herein and in this Item 4 are calculated based
	  upon the Issuer's Current Report on Form 8-K filed on February 9, 2018,
	  which states that as of January 22, 2018 there were 60,989,395 shares
	  of Common Stock outstanding.

	  The Reporting Persons do not directly own any shares of Common Stock.
	  Roivant Sciences Ltd. ("Roivant") directly holds the 37,231,342 shares
	  of Common Stock reported herein as beneficially owned by the
	  Reporting Persons. As shareholders of Roivant, the Reporting Persons
	  are filing this Schedule 13G/A because they may be deemed to have
	  dispositive power and, therefore, beneficial ownership, over the shares
	  of Common Stock directly held by Roivant by virtue of governance
	  arrangements in Roivant's bye-laws, namely, the appointment of one
	  or more independent directors (within the meaning of that term under
	  Roivant's bye-laws) to Roivant's board of directors. The filing of
	  this statement should not be deemed an admission that the
	  Reporting Persons are, for the purposes of Section 13 of the Securities
	  Exchange Act of 1934, as amended (the "Act"), the beneficial owners
	  of any securities covered by this statement.

	  Rose S. Shabet was appointed as an Executive Committee Member
	  of VGPL (as defined below), VGP, VLFGP and Opportunities GP
	  as of July 1, 2017. Therefore, Ms. Shabet now beneficially
	  owns the shares of Common Stock described herein.

	  O. Andreas Halvorsen, David C. Ott and Rose S. Shabet are
	  Executive Committee Members of certain management entities, including
	  Viking Global Partners LLC, the general partner of VGI ("VGPL"), VGP,
	  VLFGP and Opportunities GP, the sole owner of Opportunities Portfolio GP.
	  VGI provides managerial services to various investment funds, including
	  VGE, VGEII, VGEIII, VLFM and Opportunities Fund. VGP is the general partner
	  of VGE and VGEII and the investment manager of VGEIII.  VLFGP serves as
	  the investment manager of VLFM. Opportunities GP serves as the sole member
	  of Opportunities Portfolio GP. Opportunities Portfolio GP serves as the
	  general partner of Opportunities Fund.

ITEM 5.   OWNERSHIP OF FIVE PERCENT OR LESS OF A CLASS.
          If this statement is being filed to report the fact that as of the
          date hereof the Reporting Persons has ceased to be the beneficial
          owner of more than five percent of the class of securities,
          check the following.[X]

	  Daniel S. Sundheim ceased serving as an Executive Committee Member
	  of VGPL, VGP, VLFGP and Opportunities GP as of June 14, 2017.
	  Therefore, Mr. Sundheim no longer beneficially owns any of the shares
	  of Common Stock described herein.

ITEM 6.   OWNERSHIP OF MORE THAN FIVE PERCENT ON BEHALF OF ANOTHER PERSON.
          Yes, see Item 4.

ITEM 7.   IDENTIFICATION AND CLASSIFICATION OF THE SUBSIDIARY WHICH ACQUIRED
          THE SECURITY BEING REPORTED ON BY THE PARENT HOLDING COMPANY.
	  Not applicable.

ITEM 8.   IDENTIFICATION AND CLASSIFICATION OF MEMBERS OF THE GROUP.
	  Not applicable.

ITEM 9.   NOTICE OF DISSOLUTION OF GROUP.
	  Not applicable.

ITEM 10.  CERTIFICATION.
          Not applicable.
