These shares were not sold by the Reporting Person but were instead offset from the total number of vested shares received by the Reporting Person from the Issuer. The original deferred restricted stock unit grant was for 12,500 restricted stock units on November 10, 2010. The units vested and converted into shares of common stock (on a 1-for-1 basis) at a rate of 1/4 on 12/10/2011; 1/4 on 11/10/2012; 1/4 on 11/10/2013 and 1/4 on 11/10/2014. The Reporting Person elected to defer receipt of the common stock for 10 years after each tranche vesting. Until vested, the restricted stock unit shall be subject to forfeiture in the event of termination of employment or service with the Issuer. Kathleen K. Hollenbeck, Attorney-in-Fact 2021-12-13
