          Preferred Stock Purchase Rights attached to the shares may be adjusted
          in  accordance  with the  provisions  of the Plan in the  event  that,
          during  the  period  the Plan is in  effect,  the  number of shares of
          Common  Stock are  increased or decreased or changed into or exchanged
          for a different  number or kind of shares of stock or other securities
          of  the  Company  through  reorganization,  merger  or  consolidation,

          Common Stock stated above, an indeterminate  number of shares which by
          reason  of any  such  events  may be  issued  in  accordance  with the
          provisions of the Plan.

     (3)  Estimated  solely for the purpose of calculating the  registration fee
          pursuant to Rule 457 under the Securities Act of 1933, as amended (the
          "Securities Act") and based upon the average of the high and low sales

          shares  were  registered  and a filing fee in the amount of $6,699 was
          previously paid to register these shares.

     (4)  The value  attributable  to the  Preferred  Stock  Purchase  Rights is
          reflected  in the market price of the Common Stock to which the Rights
          are attached.

Item 4. Description of Securities

     Not applicable.

Item 5. Interests of Named Experts and Counsel.

     Certain legal matters in connection  with the securities  registered  under
this  Registration  Statement  will be passed upon by Charles W. Sprague,  Esq.,
Executive  Vice  President,  General  Counsel and Secretary of the Company.  Mr.
Sprague  beneficially  owns 84,697 shares of Fiserv  Common Stock,  which number
includes vested but unexercised stock options.

Item 6. Indemnification of Directors and Officers

     In  general,  the  Wisconsin  Business  Corporation  Law  provides  that  a
corporation shall indemnify  directors and officers for all reasonable  expenses
incurred  in  connection  with the  successful  defense  of  actions  arising in
connection with their service as directors and officers of the  corporation.  In
proceedings  in which the director or officer is not  successful  in the defense
thereof,  the Wisconsin  Business  Corporation Law provides that the corporation
shall indemnify a director or officer against  liability  unless the director or
officer  breached or failed to perform a duty owed to the  corporation  and such
breach or failure meets certain  specified  criteria  constituting,  in general,
some act of misconduct.  The Wisconsin  Business  Corporation  Law  specifically
states that it is the policy of Wisconsin  to require or permit  indemnification
in connection with a proceeding  involving securities  regulation,  as described
therein,  to the extent  required or permitted as described  above. In addition,
the  corporation  may  reimburse  a director  or  officer  for his  expenses  in
defending  against actions as they are incurred upon the director's or officer's
written  request  accompanied by a written  affirmation of his good faith belief
that he has not breached or failed to perform his duties to the  corporation and
a written  undertaking to repay amounts advanced if it is ultimately  determined
that  indemnification is not required under the Wisconsin  Business  Corporation
Law. A court of law may order that the corporation provide  indemnification to a
director or officer if the court finds that the  director or officer is entitled
thereto under the  applicable  statutory  provision or is fairly and  reasonably
entitled thereto in view of all the relevant circumstances,  whether or not such
indemnification is required under the applicable statutory provision.

     The  Wisconsin  Business   Corporation  Law  specifies  various  procedures
pursuant  to  which  a  director  or  officer   may   establish   his  right  to
indemnification.

     Provided that it is not determined by or on behalf of the corporation  that
the  director  or  officer  breached  or  failed  to  perform a duty owed to the
corporation  and  such  breach  or  failure  meets  certain  specified  criteria
constituting,  in general,  some act of misconduct,  a Wisconsin corporation may
provide additional rights to indemnification under its articles of incorporation
or by-laws, by written agreement,  by resolution of its board of directors or by
a vote of the holders of a majority of its outstanding shares.

     The  Registrant's  By-laws provide for  indemnification  and advancement of
expenses  of  directors  and  officers  to the  fullest  extent  provided by the
Wisconsin  Business Law. This  provision is not exclusive of any other rights to
indemnification  or the  advancement  of expenses to which a director or officer
may be entitled under any written  agreement,  resolution of directors,  vote of
shareholders,  by  law  or  otherwise.  The  general  effect  of  the  foregoing
provisions may be to reduce the  circumstances  which an officer or director may
be  required  to bear the  economic  burden  of the  foregoing  liabilities  and
expenses.

Item 7. Exemption from Registration Claimed

     Not applicable.

Item 8. Exhibits

     See Exhibit Index.

Item 9. Undertakings

     (a)  Rule 415 Offering

     The undersigned registrant hereby undertakes:

          (1) To file,  during  any  period  in which  offers or sales are being
made, a post-effective amendment to this registration statement:

               (i)  To include any  prospectus  required by Section  10(a)(3) of
                    the Securities Act of 1933;

              (ii)  To reflect  in the  prospectus  any facts or events  arising
                    after the effective date of the  registration  statement (or
                    the most recent  post-effective  amendment  thereof)  which,
                    individually  or in the  aggregate,  represent a fundamental
                    change  in the  information  set  forth in the  registration
                    statement.  Notwithstanding  the foregoing,  any increase or
                    decrease  in  volume  of  securities  offered  (if the total
                    dollar  value of  securities  offered  would not exceed that
                    which was registered) and any deviation from the low or high
                    end of the estimated maximum offering range may be reflected
                    in the form of prospectus filed with the Commission pursuant
                    to Rule 424(b) if, in the  aggregate,  the changes in volume
                    and price represent no more than a 20% change in the maximum
                    aggregate  offering price set forth in the  "Calculation  of
                    Registration  Fee"  table  in  the  effective   registration
                    statement;

              (iii) To include  any  material  information  with  respect to the
                    plan  of  distribution  not  previously   disclosed  in  the
                    registration  statement  or  any  material  change  to  such
                    information in the registration statement;

     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section
do not apply if the  information  required to be  included  in a  post-effective
amendment by those  paragraphs  is contained in periodic  reports  filed with or
furnished to the Commission by the registrant  pursuant to Section 13 or Section
15(d) of the Securities  Exchange Act of 1934 that are incorporated by reference
in the registration statement.

          (2) That,  for the  purpose of  determining  any  liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

     (b) Incorporating Subsequent Exchange Act Documents by Reference

     The  undersigned   registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c)  Indemnification  for  Liabilities  arising under the Securities
          Act of 1933

     Insofar as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Commission such  indemnification  is
against  public  policy as expressed in the  Securities  Act and is,  therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

          Plan.

     (2)  The  number  of  shares  of  Common  Stock  to be  registered  and the
          Preferred Stock Purchase Rights attached to the shares may be adjusted
          in  accordance  with the  provisions  of the Plan in the  event  that,
          during  the  period  the Plan is in  effect,  the  number of shares of
          Common  Stock are  increased or decreased or changed into or exchanged
          for a different  number or kind of shares of stock or other securities
          of  the  Company  through  reorganization,  merger  or  consolidation,

          Common Stock stated above, an indeterminate  number of shares which by
          reason  of any  such  events  may be  issued  in  accordance  with the
          provisions of the Plan.

     (3)  Estimated  solely for the purpose of calculating the  registration fee
          pursuant to Rule 457 under the Securities Act of 1933, as amended (the
          "Securities Act") and based upon the average of the high and low sales

          shares  were  registered  and a filing fee in the amount of $6,699 was
          previously paid to register these shares.

     (4)  The value  attributable  to the  Preferred  Stock  Purchase  Rights is
          reflected  in the market price of the Common Stock to which the Rights
          are attached.

Item 4. Description of Securities

     Not applicable.

Item 5. Interests of Named Experts and Counsel.

     Certain legal matters in connection  with the securities  registered  under
this  Registration  Statement  will be passed upon by Charles W. Sprague,  Esq.,
Executive  Vice  President,  General  Counsel and Secretary of the Company.  Mr.
Sprague  beneficially  owns 84,697 shares of Fiserv  Common Stock,  which number
includes vested but unexercised stock options.

Item 6. Indemnification of Directors and Officers

     In  general,  the  Wisconsin  Business  Corporation  Law  provides  that  a
corporation shall indemnify  directors and officers for all reasonable  expenses
incurred  in  connection  with the  successful  defense  of  actions  arising in
connection with their service as directors and officers of the  corporation.  In
proceedings  in which the director or officer is not  successful  in the defense
thereof,  the Wisconsin  Business  Corporation Law provides that the corporation
shall indemnify a director or officer against  liability  unless the director or
officer  breached or failed to perform a duty owed to the  corporation  and such
breach or failure meets certain  specified  criteria  constituting,  in general,
some act of misconduct.  The Wisconsin  Business  Corporation  Law  specifically
states that it is the policy of Wisconsin  to require or permit  indemnification
in connection with a proceeding  involving securities  regulation,  as described
therein,  to the extent  required or permitted as described  above. In addition,
the  corporation  may  reimburse  a director  or  officer  for his  expenses  in
defending  against actions as they are incurred upon the director's or officer's
written  request  accompanied by a written  affirmation of his good faith belief
that he has not breached or failed to perform his duties to the  corporation and
a written  undertaking to repay amounts advanced if it is ultimately  determined
that  indemnification is not required under the Wisconsin  Business  Corporation
Law. A court of law may order that the corporation provide  indemnification to a
director or officer if the court finds that the  director or officer is entitled
thereto under the  applicable  statutory  provision or is fairly and  reasonably
entitled thereto in view of all the relevant circumstances,  whether or not such
indemnification is required under the applicable statutory provision.

     The  Wisconsin  Business   Corporation  Law  specifies  various  procedures
pursuant  to  which  a  director  or  officer   may   establish   his  right  to
indemnification.

     Provided that it is not determined by or on behalf of the corporation  that
the  director  or  officer  breached  or  failed  to  perform a duty owed to the
corporation  and  such  breach  or  failure  meets  certain  specified  criteria
constituting,  in general,  some act of misconduct,  a Wisconsin corporation may
provide additional rights to indemnification under its articles of incorporation
or by-laws, by written agreement,  by resolution of its board of directors or by
a vote of the holders of a majority of its outstanding shares.

     The  Registrant's  By-laws provide for  indemnification  and advancement of
expenses  of  directors  and  officers  to the  fullest  extent  provided by the
Wisconsin  Business Law. This  provision is not exclusive of any other rights to
indemnification  or the  advancement  of expenses to which a director or officer
may be entitled under any written  agreement,  resolution of directors,  vote of
shareholders,  by  law  or  otherwise.  The  general  effect  of  the  foregoing
provisions may be to reduce the  circumstances  which an officer or director may
be  required  to bear the  economic  burden  of the  foregoing  liabilities  and
expenses.

Item 7. Exemption from Registration Claimed

     Not applicable.

Item 8. Exhibits

     See Exhibit Index.

Item 9. Undertakings

     (a)  Rule 415 Offering

     The undersigned registrant hereby undertakes:

          (1) To file,  during  any  period  in which  offers or sales are being
made, a post-effective amendment to this registration statement:

               (i)  To include any  prospectus  required by Section  10(a)(3) of
                    the Securities Act of 1933;

              (ii)  To reflect  in the  prospectus  any facts or events  arising
                    after the effective date of the  registration  statement (or
                    the most recent  post-effective  amendment  thereof)  which,
                    individually  or in the  aggregate,  represent a fundamental
                    change  in the  information  set  forth in the  registration
                    statement.  Notwithstanding  the foregoing,  any increase or
                    decrease  in  volume  of  securities  offered  (if the total
                    dollar  value of  securities  offered  would not exceed that
                    which was registered) and any deviation from the low or high
                    end of the estimated maximum offering range may be reflected
                    in the form of prospectus filed with the Commission pursuant
                    to Rule 424(b) if, in the  aggregate,  the changes in volume
                    and price represent no more than a 20% change in the maximum
                    aggregate  offering price set forth in the  "Calculation  of
                    Registration  Fee"  table  in  the  effective   registration
                    statement;

              (iii) To include  any  material  information  with  respect to the
                    plan  of  distribution  not  previously   disclosed  in  the
                    registration  statement  or  any  material  change  to  such
                    information in the registration statement;

     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section
do not apply if the  information  required to be  included  in a  post-effective
amendment by those  paragraphs  is contained in periodic  reports  filed with or
furnished to the Commission by the registrant  pursuant to Section 13 or Section
15(d) of the Securities  Exchange Act of 1934 that are incorporated by reference
in the registration statement.

          (2) That,  for the  purpose of  determining  any  liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

     (b) Incorporating Subsequent Exchange Act Documents by Reference

     The  undersigned   registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c)  Indemnification  for  Liabilities  arising under the Securities
          Act of 1933

     Insofar as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Commission such  indemnification  is
against  public  policy as expressed in the  Securities  Act and is,  therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.
