Explanation of Responses:

* 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) These restricted stock units each represent a contingent right to receive one share of Fiserv, Inc. common stock. The restricted stock units vest 100% on the earlier of: (i) the first anniversary of the grant date; or (ii) immediately prior to the first annual meeting of shareholders after the grant date.
(2) Adjusted to reflect the two-for-one split of Fiserv, Inc. common stock distributed at the close of business on March 19, 2018 to holders of record on March 5, 2018.
(3) These deferred compensation notional units were allocated under the Fiserv, Inc. Non-Employee Director Deferred Compensation Plan (the "Plan"), under which director fees otherwise payable in cash may be deferred in exchange for the allocation of notional units under the Plan. The number of notional units credited is calculated by dividing the amount of compensation that is deferred by the closing price of the company's common stock on the date of deferral, or last business day prior. Upon termination of the reporting person's service to the company, each notional unit will be settled in shares of Fiserv, Inc. common stock on a one-for-one basis.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
