Pursuant to the Company's automatic grant program for non-employee directors under the 2009 Share Option/Share Issuance Plan (the "Plan"), on April 10, 2013, the effective date of his appointment, Mr. Owyang was granted an option to purchase 5,000 common shares ("Common Shares") of the Company (the "Option"). The exercise price of the Option is $9.19, which represents the closing sales price of the Common Shares on The NASDAQ Global Market on such date. The Option will be immediately exercisable for any or all shares. However, any unvested shares underlying the Option are subject to the Company's repurchase rights under the Plan. The shares underlying the Option will vest, and the Company's repurchase right will lapse, on the date of the next succeeding regular annual shareholder's meeting following the grant date if he continues his Board service through such annual meeting date. The Option has a term of 10 years from the grant date, subject to early termination following his cessation of Board service.

On April 12, 2013, the Company issued a press release announcing the appointment of Dr. Owyang, a copy of which is attached as Exhibit 99.1 hereto and incorporated herein by reference. The foregoing description of the terms of the Option is only a summary and qualified in its entirety by the Plan, a copy of which is filed as Exhibit 10.3 to the Registration Statement on Form F-1 filed on March 31, 2010.
