Item 4 — Purpose of Transaction
Except as described in this Item 4, Dr. Huang has no present plans or proposals that relate to or would result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Form Schedule 13D.

In his capacity as a director and senior executive officer of the Issuer, Dr. Huang participates in deliberations of the Issuer's senior management and directors in the normal course of the Issuer's business that could involve any of the matters set forth in subparagraphs (a)-(j) of the instructions to Item 4 from time to time, and, consistent with his fiduciary duties as an officer, may make proposals or recommendations to the Issuer's board of directors that could involve such matters from time to time. In addition, as a member of the Issuer's senior management, Dr. Huang participates in Issuer compensatory plans, including plans pursuant to which awards of equity securities are made (including, from time to time, to Dr. Huang), in the ordinary course of business, generally on an annual basis.
