*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Each PSU represents a contingent right to receive one RBA common share or the economic equivalent thereof.
(2)	The RBA Compensation Committee determined that the PSUs, previously granted to the reporting person, are eligible for vesting because certain performance criteria were satisfied.
(3)	The PSUs vest on 3/01/2019. The common shares underlying vested PSUs or the cash value thereof (as determined by the Committee in accordance with the RBA Senior Executive Performance Share Unit Plan) will be paid to the reporting person, net of tax, as soon as practicable following the end of the month in which the PSUs vest.
(4)	Each dividend equivalent right represents a contingent right to receive one RBA common share or the economic equivalent thereof. DERs accrued in respect of the 2016 PSUs vest and become exercisable concurrently with the PSUs to which they relate.
