Explanation of Responses:

( 1 )Starboard Value LP ("Starboard") serves as the investment manager or manager of certain managed accounts and private investment funds (collectively, the "Starboard Accounts"), which hold the securities reported herein and as such may be deemed to beneficially own such securities. The Reporting Person, as a Managing Member of Starboard, may be deemed to beneficially own the securities directly held by the Starboard Accounts for purposes of Section 16 of the Securities Exchange Act of 1934, as amended. The Reporting Person expressly disclaims beneficial ownership of such securities except to the extent of his pecuniary interest therein. ( 2 )Each deferred share unit ("DSU") represents the economic equivalent of one RBA common share. ( 3 )Following the reporting person ceasing to hold any position as a director of RBA or any of its subsidiaries and not otherwise being employed by RBA or any of its subsidiaries ("Termination"), a lump sum cash payment will be made by RBA to the reporting person, net of tax withholding, calculated by multiplying the number of DSUs by the fair market value of one RBA common share as of (i) the 24th business day after the first publication by or on behalf of RBA of interim financial statements and MD&A for the fiscal quarter of the corporation following such Termination or (ii) where the Termination occurs in RBA's fourth fiscal quarter, the 24th business day (or such fewer number of business days as may be determined by the Committee) after the first publication by or on behalf of RBA of annual financial statements and MD&As for such fiscal year of RBA. ( 4 )The dividend equivalent rights accrued in respect of the reporting person's DSUs, and become exercisable and payable concurrently with the DSUs. Each dividend equivalent right represents a contingent right to receive the economic equivalent of one RBA common share. ( 5 )Pursuant to the terms of the Articles of Amendment setting forth the rights, preferences and privileges of the Series A Senior Preferred Shares, without par value (the "Series A Preferred Shares"), holders of the Series A Preferred Shares have the right to convert their Series A Preferred Shares any time or times on or after February 1, 2023, into a number of Common Shares, without par value (the "Common Shares") equal to the face amount of such Series A Preferred Shares multiplied by the then-applicable conversion rate (the "Conversion Rate"). The current Conversion Rate is 0.0139696 Common Shares per $1.00 face amount of Series A Preferred Shares, subject to customary anti-dilution adjustment provisions. The Series A Preferred Shares have no stated maturity.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
