Explanation of Responses:

( 1 )The number of Market Share Units (Common Stock equivalents) (MSUs) has been corrected to report the actual number of MSUs acquired upon certified vesting of MSUs awarded to the reporting person on October 14, 2013. The original report incorrectly reported the acquisition of 722 MSUs. The vested MSUs will be settled by issuance of shares of Common Stock not later than November 15, 2016. ( 2 )The total reported as of the transaction date included 990.007 shares held in the WD-40 Company Profit Sharing Plan (Company Stock Fund) account. The total also included 1,547 Restricted Stock Units (Common Stock equivalents) (RSUs), all of which are subject to future vesting, 1,585 MSUs (target number) awarded to the reporting person in 2014 and 2015, all of which are subject to future vesting, 1,083 vested MSUs and 190 vested Deferred Performance Units (Common Stock equivalents) (DPUs). The vested DPUs will be settled solely with Issuer Common Stock following termination of employment. The total reported as of October 10, 2016 does not include the award of RSUs on October 11, 2016 that were included on the original Form 4 report filed on October 12, 2016.
