Departure of Michael Chu from Board of Directors

On April 23, 2016, Michael Chu notified Restoration Hardware Holdings, Inc. (the “Company”) of his decision to resign from the board of directors (the “Board”) effective as of April 28, 2016. Mr. Chu informed the Company of his need to resign due the increased responsibilities he now holds as co-CEO of L Catterton, following the recently announced merger between Catterton and L Capital Partners (an investment group affiliated with luxury product maker LVMH and major LVMH shareholder Groupe Arnault).

Mr. Chu’s decision to resign from the Board is not related to any disagreement on any matter relating to the Company’s operations, policies or practices.

Restoration Hardware’s Chairman and Chief Executive Officer, Gary Friedman, said, “Michael Chu is one of the most exceptional individuals that I have had the pleasure of working with in my long career in retail. Michael has made outstanding contributions to the Company during his eight years of service on the Board – well beyond Catterton’s ownership in RH – and has been a great partner to the management team and the rest of the Board. On behalf of myself, the Board and the entire RH team, I want to express our sincere thanks to Michael for his vision and his support to help us build RH into one of the great consumer businesses of our time. He will be greatly missed.”

Appointment of Keith Belling to Board of Directors

The Board has appointed Keith Belling to fill the vacancy created by the departure of Michael Chu effective on April 28, 2016. Keith Belling will serve as a Class III director with a term expiring at the Company’s 2018 annual meeting of stockholders.

Mr. Belling is a successful entrepreneur, operator and marketing professional, who has developed, launched, led and provided strategic counsel to emerging and established businesses. Mr. Belling is the Founder and Chairman and former Chief Executive Officer of the award winning snack company popchips. Mr. Belling also serves as an advisor to several other innovative companies that range from next generation food, nutrition and specialty ingredients company TerraVia (formerly Solazyme), startup Modern Meadow, and real estate company LBA Realty. Mr. Belling also founded and served as Chief Executive Officer of e-commerce company AllBusiness.com, which was acquired by NBCi.

Mr. Friedman said, “We are thrilled to have Keith join the RH Board. His passion as a founder and creator of new business concepts aligns exceptionally well with our continuing focus on innovation at RH. We believe Keith is a perfect fit as we continue our pursuit of becoming one of the most admired brands in the world.”

Mr. Belling previously entered into an advisory services agreement with the Company dated April 10, 2015. Pursuant to such agreement, Mr. Belling provided advisory services to the Company and the Board of Directors. Mr. Belling received annual compensation pursuant to the advisory services agreement generally in alignment with the level of compensation paid by the Company to outside directors on its Board of Directors including an annual fee of $120,000, a fee of $1,500 or $2,500 for each Board meeting attended and an annual grant of restricted stock units with an aggregate value equal to $125,000 at the time of grant. The advisory agreement will be replaced by Mr. Belling’s compensation as a member of the Board.

Notice of Intended Departure from Board by Thomas Mottola

Thomas Mottola notified the Company on April 26, 2016, that he intends to resign from the Board effective on the earlier of (i) such time as the Board has identified and has approved the appointment to the Board of another independent director under applicable rules of the New York Stock Exchange who is able to assume the vacancy in the Board that will be created by the resignation of Mr. Mottola, and (ii) immediately prior to the opening for business on the day of the Company’s 2016 annual meeting of stockholders. Mr. Mottola cited as the reason for his departure the competing demands on his time from other professional and business ventures in which he is involved. The Board is actively searching for an independent director in order to replace Mr. Mottola. Mr. Mottola’s decision to resign from the Board does not involve any disagreement on any matter relating to the Company’s operations, policies or practices.

Gary Friedman, commented, “On behalf of myself, the Board and the entire RH team, I want to thank Tommy for his leadership and guidance in support of the Company. He has made important contributions to shaping the brand and business we are today.”
