In connection with her retirement, the Company and Ms. Hodges are entering into a transition and retirement agreement to provide for the smooth and orderly transition of Ms. Hodges’ duties. During such transition period, of up to six months, the Company will pay Ms. Hodges her current base salary and other benefits. Thereafter, Ms. Hodges has agreed to serve as a special advisor to the Company’s Chief Executive Officer for a period of up to twenty-four months (the “Special Advisor Term”). During the first twelve months of the Special Advisor Term, Ms. Hodges will be paid at her current base salary rate, which will be reduced by 50% for the remainder of the Special Advisor Term, and she will otherwise remain eligible for employee benefits during the Special Advisor Term, including annual bonus and equity grant opportunities. Ms. Hodges’ equity awards will continue to remain outstanding and vest under the existing terms and conditions set forth in the governing plan documents and applicable equity agreements through the end of the Special Advisor Term.

In accordance with the succession planning processes of the Board of Directors of the Company (the “Board”), the Board has appointed Nathaniel “Nate” Sisitsky, as Chief Legal Officer, to succeed Ms. Hodges as Chief Legal Officer and Corporate Secretary, effective as of the Effective Date.

A copy of the press release issued in connection with the transition described above is furnished with this Current Report on Form 8-K (the “Form 8-K”) as Exhibit 99.1.
