Exhibit A

EQUITY COMPENSATION

Following the Commencement Date, you will be granted options to acquire certain number of common shares of the Company (“Pre-IPO Options”) on the date of completion of the IPO (“Grant Date”) under the Company’s 2010 Equity Incentive Plan (the “2010 Equity Incentive Plan”) and in accordance with the following key terms:

Number of Shares:		US$2,000,000/IPO price per share.

Exercise price:		30% of the IPO price per share.

Vesting Schedule:		60% of the Pre-IPO Options: 1 year from the Grant Date
		20% of the Pre-IPO Options: 2 years from the Grant Date
		20% of the Pre-IPO Options: 3 years from the Grant Date

The Executive represents that he understands and agrees that, although the Company is actively preparing an IPO, the occurrence of the IPO is also dependent on market and other external factors and therefore cannot be guaranteed. Notwithstanding the foregoing Vesting Schedule, no Pre-IPO Options shall vest before the completion of the IPO. For the avoidance of doubt, upon the completion of the IPO, the Pre-IPO Options shall vest and become exercisable in accordance with the Vesting Schedule. In the event that the Employment is terminated for any reason pursuant to the terms of this Agreement before the completion of the IPO, the Executive shall not be granted the Pre-IPO Options as provided herein.

Any unvested options as of the date of the Executive’s departure from the Company will automatically be cancelled and will revert to the Company.

Notwithstanding anything to the contrary and without prejudice to the other rights and remedies of the Company under this Agreement, in the event that the Executive leaves the Company to join a competitor of the Company (as the Company may determine) during the Employment Term, any unexercised options (vested and unvested) will be immediately cancelled and will revert to the Company on the date of resignation.
