Upon commencement of services to the Board, Dr. Arienzo will be appointed to the Audit Committee of the Board.

Dr. Arienzo has more than three decades of technical and managerial experience in technology industries, including the semiconductor and power-electronics industries. Since 2013 she has served as vice president of operations at Fujifilm Dimatix, Inc., a leading supplier of piezoelectric industrial print heads. Previously, she was CEO and a director of ArrayPower, a developer of software-defined inverter technology for solar-energy systems. Her prior experience includes a series of executive and technical roles at NXP Semiconductors (and its predecessor, Philips Semiconductor), IBM Corp. and AT&T Bell Laboratories, among others.

Upon commencement of services to the Board, and in consideration of services to the Company as a director, Dr. Arienzo will be granted an equity award in the form of restricted stock units of the Company’s common stock (the “Initial Grant”) under the Power Integrations 2007 Equity Incentive Plan (the “2007 Plan”) with an aggregate fair value of approximately $25,000. The Initial Grant will vest on the date of the Company’s next annual meeting of stockholders (currently scheduled for May 19, 2017), provided Dr. Arienzo is still serving as a director on that date. Notwithstanding the foregoing, the Initial Grant would be deemed fully vested upon the occurrence of a Change of Control (as defined in the 2007 Plan). Beginning on July 1, 2017, Dr. Arienzo will receive annual equity compensation to the Directors Equity Compensation Program consistent with the Company’s other non-employee directors, which is a grant of a stock option or restricted stock units, at her election, under the 2007 Plan with an aggregate value of $100,000, which would vest in full effective immediately prior to the commencement of the Company’s first annual meeting of stockholders in the year following the year of the grant date, provided that the recipient is still providing services to the Company as a director and provided, further, that 50% of the shares subject to such equity award would be deemed fully vested upon the occurrence of a “Change of Control”, as such term is defined in the 2007 Plan.

As a non-employee director, Dr. Arienzo will also receive $9,000 per quarter for service on the Board. In addition, as a member of the Audit Committee, Dr. Arienzo will receive an additional $2,000 per quarter to serve on the committee.
