| Awards |

The Amended 2018 LTIP provides for the grant of ISOs, NQSOs, SARs, restricted shares, RSUs, performance bonus awards, performance share units awards, other share or cash-based awards, and dividend equivalents. All awards under the Amended 2018 LTIP are set forth in award agreements, which detail all terms and conditions of the awards, including any applicable vesting and payment terms and post-termination exercise limitations. No fractional shares may be issued or delivered pursuant to the Amended 2018 LTIP or any award thereunder.

Options . Options provide for the purchase of ordinary shares in the future at an exercise price set on the grant date. ISOs, by contrast to NQSOs, may provide tax deferral beyond exercise and favorable capital gains tax treatment to their holders if certain holding period and other requirements of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), are satisfied.

The exercise price of an SAR may not be less than 100% of the fair market value of the underlying share on the date of grant (except with respect to certain substitute SARs granted in connection with a corporate transaction) and the term of an SAR may not be longer than ten years. Vesting conditions determined by the plan administrator may apply to SARs and may include continued service, performance and/or other conditions. SARs will be settled in cash or ordinary shares
