, or in a combination of both, as determined by the plan administrator .

Restricted Shares . A restricted share award is an award of nontransferable ordinary shares that remain forfeitable unless and until specified vesting conditions are met. Vesting conditions applicable to restricted shares may be based on continuing service, the attainment of performance goals and/or such other conditions as the plan administrator may determine. In general, restricted shares may not be sold or otherwise transferred until restrictions are removed or expire. Participants holding restricted shares will have voting rights and will have the right

to receive dividends; however, dividends may not be paid until the applicable restricted shares vest.

Restricted Share Units . RSUs are contractual promises to deliver ordinary shares (or the fair market value of such shares in cash) in the future, which may also remain forfeitable unless and until specified vesting conditions are met. RSUs generally may not be sold or transferred until vesting conditions

are removed or expire. The shares underlying RSUs will not be issued until the RSUs have vested, and recipients of RSUs generally will have no voting or dividend rights prior to the time the RSUs are settled in shares. Delivery of the shares underlying RSUs may be deferred under the terms of the award or at the election of the participant, if the plan administrator permits such a deferral. On the settlement date or dates, we will issue to the participant one unrestricted, fully transferable ordinary share (or the fair market value of one such share in cash) for each vested and non-forfeited RSU.

Performance Share Units and Performance Bonus Awards . Performance share unit awards are denominated in shares or unit equivalents, and performance bonus awards are denominated in cash. Each may be linked to one or more performance or other criteria as determined by the plan administrator.

Other Share or Cash Based Awards . Other share or cash based awards are awards of cash, fully vested ordinary shares, and other awards valued wholly or partially by referring to, or otherwise based on, our ordinary shares. Other share or cash based awards may be granted to participants and may also be available as a payment form in the settlement of other awards, as standalone payments or as payment in lieu of base salary, bonus, fees, or other cash compensation otherwise payable to any individual who is eligible to receive awards. The plan administrator will determine the terms and conditions of other share or cash based awards, which may include vesting conditions based on continued service, performance, and/or other conditions.

Dividend Equivalents . Dividend equivalents represent the right to receive
