Exhibit 10

FISERV, INC.

STOCK OPTION PLAN

(as amended and restated as of February 11, 2003)

Section 1. Purpose. The purpose of the Fiserv, Inc. Stock Option Plan (the “Plan”) is to promote the interest of Fiserv, Inc. (the “Company”) and its Subsidiaries (the Company and each such Subsidiary being herein each referred to as a “Fiserv Group Company”) by (a) providing an incentive to employees, and to directors who are not employees, of the Fiserv Group Companies which will attract, retain and motivate persons who are able to make important contributions to the Company’s growth, profitability and long-term success, and (b) furthering the identity of interests of the Optionees with those of the Company’s shareholders through stock ownership opportunities. Options to be issued under the Plan may be “incentive stock options” as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or “non-qualified stock options” (“NQSOs”), which do not qualify as “incentive stock options” (“ISOs”), but the Company makes no representation or warranty as to the qualification of any Option as an incentive stock option under the Code.

Section 2. Definitions. For purposes of this Plan, the following terms used herein shall have the following meanings, unless a different meaning is clearly required by the context.

understanding: (A) arises solely from a revocable proxy or consent given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations under the Act and (B) is not also then reportable on Schedule 13D under the Act (or any comparable or successor report); or

Section 6. Terms and Conditions of Options.

Subject to the Plan, the terms and conditions of each Option granted under the Plan shall be specified by the Committee (the Board of Directors with respect to grants to Non-Employee Directors) and shall be set forth in an option agreement between the Company and the Optionee in such form as the Committee shall approve. The terms and conditions of any Option granted hereunder need not be identical to those of any other Option granted hereunder.

The terms and conditions of each Option shall include the following:

6.1 The option price shall be fixed by the Committee, provided, however, that in the case of an ISO, the option price may not be less than the fair market value of the shares of Common Stock subject to the Option on the date the Option is granted, and provided, further, however, that if at the time an ISO is granted, the Optionee owns (or is deemed to own under Section 424(d) of the Code) stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, any of its Subsidiaries or a Parent, the option price of such ISO shall not be less than 110% of the fair market value of the Common Stock subject to such ISO on the date of grant. In addition, with respect to at least 95% of the number of shares of Common Stock for which Options may be granted under this Plan as of February 14, 2000, the option price may not be less than the fair market value of the shares of Common Stock subject to the Option on the date the Option is granted.

6.2 Options shall not be transferable otherwise than by will or the laws of descent and distributions, and during an Optionee’s lifetime, an option shall be exercisable only by the Optionee or the Optionee’s legal guardian.

6.3 The Committee shall fix the term of all Options granted pursuant to the Plan (including the date on which such Option shall expire and the conditions under which it terminates earlier), provided, however, that the term of an ISO may not exceed ten years from the date such Option is granted, and provided, further, however, that if at the time an ISO is granted, the Optionee owns (or is deemed to own under Section 424(d) of the Code) stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, any of its Subsidiaries or a Parent, the

term of such ISO may not exceed five years from the date of grant. Each Option shall be exercisable in such amount or amounts, under such conditions, and at such times or intervals or in such installments as shall be determined by the Committee. The Committee may, in its sole discretion, establish a vesting provision for any Option relating to the time or the circumstances when the Option may be exercised by the Optionee.

6.4 Payment of the option price of an Option may be made in cash, with shares of Common Stock held by the Optionee for more than six months prior to payment or otherwise in accordance with law as the Committee may determine from time to time. In the event that any Fiserv Group Company is required to withhold any Federal, state or local taxes or other amounts in respect of any income realized by the Optionee in respect of an Option granted hereunder, in respect of any shares acquired pursuant to the exercise of an Option or in respect of the disposition of an Option or any shares acquired pursuant to the exercise of an Option, the Company may deduct (or require the Fiserv Group Company to deduct) from any payments of any kind otherwise due to such Optionee cash or with the consent of the Committee (in the stock option contract or otherwise) shares of the Company’s Common Stock the aggregate amount of such Federal, state or local taxes and other amounts required to be so withheld. Alternatively, the Company may require such Optionee to pay to the Company in cash, promptly on demand, or make other arrangements satisfactory to the Company regarding payment to the Company of, the aggregate amount of any such taxes and other amounts.

6.5 The aggregate fair market value (determined at the time the Option is granted) of the shares of Common Stock for which an eligible employee may be granted ISOs under the Plan or any other plan of the Company, any of its Subsidiaries or a Parent which are exercisable for the first time by such employee during any calendar year shall not exceed $100,000. Such limitation shall be applied by taking ISOs into account in the order in which they were granted. Any Option (or portion thereof) granted in excess of such amount shall be treated as an NQSO.

6.6 In no case may a fraction of a share be exercised or acquired pursuant to the Plan.

6.7 Without prior approval of the Company’s shareholders, Options issued under this Plan will not be repriced, replaced or regranted through cancellation or by lowering the option price of a previously granted Option.

Section 7. Effect of Changes in Capitalization or Change of Control.

7.1 Changes in Stock. If the outstanding shares of Common Stock are increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason of any recapitalization, reclassification, stock split, reverse split, combination of shares, exchange of shares, stock dividend or other distribution payable in capital stock, or other increase or decrease in those shares effected without receipt of consideration by the Company occurring after the date an Option is granted, a proportionate and appropriate adjustment will be made by the Company in the number and kind of shares subject to the Option, so that the proportionate interest of the Optionee immediately following that, to the extent

practicable, will be the same as immediately prior to that event. Any such adjustment in the Option will not change the total exercisable price with respect to shares subject to the unexercisable portion of the Option but will include a corresponding proportionate adjustment in the exercise price per share. In the event of any distribution to the Company’s shareholders of securities of any other entity or other assets (other than dividends payable in cash or stock of the Company) without receipt of consideration by the Company, the Company, in the manner the Board of Directors or the Committee deems appropriate, will adjust (i) the number and kind of shares subject to the Option and/or (ii) the exercise price of the Option to reflect that distribution.

7.2 Reorganization in Which the Company is the Surviving Company. Subject to Subsection 7.3, if the Company is the surviving Company in any reorganization, merger, or consolidation of the Company with one or more other companies or other entities, each Option will pertain to and apply to the securities to which a holder of the number of shares of stock subject to the Option would have been entitled immediately following that reorganization, merger or consolidation, with a corresponding proportionate adjustment of the exercise price per share so that the aggregate exercise price after that event will be the same as the aggregate exercise price of the shares remaining subject to the Option immediately before that reorganization, merger, or consolidation.

7.3 Change of Control. If a Change in Control of the Company occurs, the Board of Directors may (i) make provisions for the continuation of each Option, (ii) reach an agreement with the acquiring or surviving entity that the acquiring or surviving entity will assume the obligation of the Company under each Option, (iii) reach an agreement with the acquiring or surviving entity that the acquiring or surviving entity will convert each Option into an option of at least equal value, determined as of the date of the transaction, to purchase stock of the acquiring or surviving entity, (iv) terminate all Options outstanding under the Plan effective at the date of the applicable transaction and, within 60 days after the date of the applicable transaction, make a cash payment to each Optionee equal to the difference between the exercise price of the Optionee’s Option and the fair market value, as of the date of the applicable transaction, of the shares subject to the Option (all of which shall be vested as of the date of the applicable transaction) or (v) vest all shares subject to the Options and allow them to be immediately exercisable at least 30 days immediately prior to the date of the applicable transaction. The Board of Directors must determine that any such modification in clause (i), (ii) or (iii) above does not have a substantial adverse economic impact on the Optionee, as determined at the time of the transaction.

7.4 Adjustments. Adjustments required by this Section relating to the Common Stock will be made by the Board of Directors, whose determination in that respect will be final, binding and conclusive. No fractional shares of Common Stock will be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall be eliminated in each case by rounding downward to the nearest whole share.

Section 8. Effect of the Plan on Employment Relationship. Neither this Plan nor any Option granted hereunder shall be construed as conferring upon any Optionee any right to continue in the employ of any Fiserv Group Company or limit in any respect any right of any Fiserv Group Company to terminate such Optionee’s employment at any time without liability, or to continue as a Non-Employee Director.

Section 9. Amendment of the Plan. The Board of Directors may amend or restate the Plan from time to time as it deems desirable, provided, however, that, without the approval of the holders of a majority of the shares of Common Stock of the Company present, or represented, and entitled to vote at any meeting duly held in accordance with the applicable laws of the State of Wisconsin, the Board of Directors may not (a) increase the maximum number of shares of Common Stock for which Options may be granted under this Plan (other than increases due to adjustment in accordance with Section 7 hereof), (b) materially increase the benefits accruing to participants under the Plan, (c) change the eligibility requirements to receive Options hereunder or (d) make any change for which applicable law requires shareholder approval.

Section 10. Termination of the Plan. The Board of Directors may terminate the Plan at any time. No Option may be granted hereunder after termination of the Plan. No ISO may be granted under the Plan more than ten years after the date on which the Plan was adopted. The termination or amendment of the Plan shall not alter or impair any rights or obligations under any Option theretofore granted under the Plan, without the consent of the Optionee.

Section 11. Effective Date of the Plan. This Plan (and as amended or restated from time to time) will become effective on the date on which it is approved by the Board of Directors. This Plan if amended or restated in any material respect is subject to approval by the holders of the majority of the shares of Common Stock of the Company present, or represented, and entitled to vote at the next meeting duly held in accordance with the applicable laws of the State of Wisconsin. No Option granted hereunder may be exercised prior to such approval, provided, however, that the date of grant of any Option shall be determined as if the Plan had not been subject to such approval. Notwithstanding the foregoing, if any material amendment or restatement is not approved by a vote of shareholders within 12 months after it is adopted by the Board of Directors, the amendment or restatement, as the case may be, shall be null and void, the Plan as in effect prior to such amendment or restatement, as the case may be, shall continue in full force and effect and any Options granted pursuant to such amendment or restatement, as the case may be, shall terminate.

Section 12. Governing Law. This Plan, the Options and all related matters shall be governed by, and construed in accordance with, the laws of the State of Wisconsin, without regard to choice of law provisions. Neither the Plan nor any agreement pursuant to the Plan shall be construed or interpreted with any presumption against any Fiserv Group Company by reason of the Fiserv Group Company having drafted or adopted the Plan or agreement. The invalidity, illegality or unenforceability of any provision in the Plan or in any agreement pursuant to the Plan shall not affect the validity, legality or enforceability of any other provision, all of which shall be valid, legal and enforceable to the fullest extent permitted by applicable law.

Board of Directors approved: February 11, 2003
