        <footnote id="F1">These deferred compensation notional units were allocated under the Fiserv, Inc. Non-Employee Director Deferred Compensation Plan (the &quot;Plan&quot;), under which director fees otherwise payable in cash may be deferred in exchange for the allocation of notional units under the Plan.  This Form 4 reports the crediting of units under the Plan on June 30, 2009 in respect of $18,000 of deferred comnpensation.  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.  On June 30, 2009, the closing price of Fiserv's common stock was $45.71 per share.  Upon termination of the reporting person's service to the company, each notional unit will be settled in shares of Fiserv common stock on a one-for-one basis.</footnote>
