 Since STAAR PSUs are being converted into Alcon RSUs, the performance conditions applicable to the STAAR PSUs are                                                                                                                                                                                                                                                       
 being eliminated, which impacts vesting. The STAAR PSUs were granted with performance conditions, pursuant to which the PSUs could be earned in up to five tranches through December 2027. Vesting varied based on when the performance conditions were                                                                                                                 
 satisfied for each tranche; once performance was satisfied for a tranche, half of the earned PSUs would vest, with half vesting on the one-year anniversary of such date. As performance is being deemed achieved                                                                                                                                                       
 at 100% of target, the STAAR PSUs that are converted into Alcon RSUs will no longer be subject to the variable vesting of the original PSUs. Instead, these awards will be subject to vesting as to 50% on the 15th day of the second month following the quarter in which the closing occurs, with the remaining 50% vesting on the one-year anniversary of such date. |

 “double-trigger” vesting provision under the terms of the STAAR equity plan, which provide that, following the closing of the Alcon merger, the Alcon RSUs received upon conversion of the STAAR PSUs will be accelerated and vest in full if 
 the award holder’s employment is involuntarily terminated within 12 months following the closing (i) for “good reason” by the award holder or (ii) by the Company other than for “cause”.                                                     |
