| 3) | For eligible executive officers of TSMC: The maximum number of RSAs that may be vested in each year will be set as 110%, among which 100% will be subject to a calculation based on TSMC’s relative Total Shareholder Return (“TSR”, including capital gains and dividends) achievement to determine the number of RSAs to be vested; this number will be further subject to a modifier to increase or decrease up to 10% based on the Compensation Committee’s (rename to Compensation and People Development Committee from February 14, 2023) evaluation of TSMC’s Environmental, Social, and Governance (“ESG”) achievements. The number of shares so calculated should be rounded down to the nearest integral.
