Explanation of Responses:

*	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)	Represents distributions by the Martin Cohen 1998 Family Trust as part of Mr. Cohen's long-term estate planning, consisting of 400,000 shares distributed on May 17, 2017 and the remaining 940,701 shares distributed on April 26, 2019, in each case, to the named beneficiaries of such trust, who are members of Mr. Cohen's family. The distribution of 400,000 shares on May 17, 2017 was previously not reported as a separate transaction on Form 4, but the balance of shares held by the Martin Cohen 1998 Family Trust since that time has reflected such distribution. A member of Mr. Cohen's family serves as trustee of the trust. Mr. Cohen disclaims beneficial ownership of these shares, and the filing of this Form 4 is not an admission that Mr. Cohen was the beneficial owner of these shares for purposes of Section 16 or for any other purpose.
(2)	Shares held by the Martin Cohen 2018 Revocable Trust. Mr. Cohen and a member of his family serve as trustees of the trust. Mr. Cohen disclaims beneficial ownership of these shares except to the extent of his pecuniary interest.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
