*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Restricted stock award granted to reporting person under the Issuer's Second Amended and Restated 2012 Omnibus Incentive Plan. The award will vest in three equal annual installments beginning on August 20, 2017. The original Form 4 filing inadvertently overstated the number of shares of restricted stock granted to the reporting person.
(2)	Reflects the correct amount of shares of common stock beneficially owned directly by the reporting person following this transaction, which otherwise was reported accurately in the original Form 4 filing.
(3)	Represents interests in trusts and limited partnerships held for the benefit of members of the reporting person's immediate family and others. The reporting person disclaims beneficial ownership of stock in the trusts and limited partnerships except to the extent of his pecuniary interest therein. This indirect beneficial ownership was reported accurately in the original Form 4 filing.
(4)	The original Form 4 filing inadvertently omitted information with respect to this grant of options to the reporting person.
(5)	These options vest in four equal annual installments beginning on August 20, 2017.
