                                   THE COMPANY

         Fiserv,  with  operations in 75 cities,  including 15 cities in Canada,
England and  Singapore,  is a leading  independent  provider of  financial  data
processing systems and related  information  management services and products to
banks, credit unions,  mortgage banks,  savings institutions and other financial
intermediaries.  These services and products are based  primarily on proprietary
software  developed  by Fiserv  and  maintained  on  computers  located  at data
processing  centers  throughout  the  United  States.  Fiserv  is  ranked as the
nation's leading data processing provider for banks and savings  institutions in
terms of total clients served and is the nation's second leading data processing
provider for credit unions and mortgage banks.  Fiserv directly supports account
and transaction  processing  software systems for approximately  3,383 financial
institutions;  maintaining  approximately  50 million  service bureau  accounts.
Fiserv  delivers  this  account and  transaction  processing  in all four of the
traditional  delivery modes:  service bureau;  facilities  management;  resource
management;  and in-house  solutions.  Fiserv also provides  electronic  banking
services,  which  include  Automated  Teller  Machine  ("ATM")/Electronic  Funds
Transfer   ("EFT")   services  to   financial   institutions,   and   processing
approximately 200 million ATM transactions annually.  Fiserv also provides check
and share draft remittance and back-office processing to financial institutions,
handling  approximately  over 3.6 billion  prime pass items per year through its
regional item processing centers located in over 45 cities in North America.  In
addition,  Fiserv  provides  trust  administration  services  for IRAs and other
retirement plans, and furnishes microcomputer software to financial institutions
for executive  information and decision support  systems.  The total client base
served by  Fiserv  includes  more  than  5,000  financial  institutions.  Fiserv
believes that its focus on customer  service and the  contractual  nature of its
business, combined with its historical renewal experience,  provide a high level
of recurring revenues.

         Since  Fiserv's  formation  in 1984,  it has  expanded  its  operations
through  over 60  acquisitions  and  internally  through  the growth of existing
clients.  From 1988 to 1996,  Fiserv's revenues increased from $125.0 million to
$798.3  million,  its operating  income  increased  from $15.5 million to $123.6
million and its net income grew from $9.2 million to $61.7 million.  During this
period, net income per common and common equivalent share increased from $.33 to
$1.34.

                               RECENT DEVELOPMENTS

         On March 2, 1997,  Fiserv  announced  that it had  signed a  definitive
agreement to acquire BHC Financial,  Inc. ("BHC") pursuant to a  stock-for-stock
merger under which Fiserv will acquire all of the outstanding  shares of BHC for
$33.50 per  share,  subject  to  receiving  pooling  accounting  treatment.  The
exchange  ratio will be determined by taking the average of the closing price of
Fiserv  Common  Stock for the last 20 trading days ending two trading days prior
to  closing.  The  agreement  is  subject to all  normal  conditions  of closing
including  receipt of all  necessary  regulatory  consents  and BHC  shareholder
approval.

         BHC, based in Philadelphia,  provides securities processing and support
services to banks,  insurance  companies,  brokerage  firms,  money managers and
mutual fund companies.  It currently processes  approximately  10,000 integrated
trade executions and clearings per day. In 1996, BHC reported  revenues of $81.2
million, net income of $18.0 million and earnings per share of $2.69,  increases
of 24%, 29% and 39%, respectively, over the previous year's levels.








                                 USE OF PROCEEDS

         All  proceeds  from the sale of the Shares to be sold  pursuant to this
Prospectus  will  be  for  the  account  of  the  Selling  Shareholders.   As  a
consequence,  the Company  will not receive  any  proceeds  from the sale of the
Shares offered by the Selling Shareholders.

                                 DIVIDEND POLICY

         The  Company  has not paid cash  dividends  on its  Common  Stock.  The
Company intends to retain earnings for use in its business and, therefore,  does
not  anticipate  paying  any  cash  dividends  in the  foreseeable  future.  The
Company's  existing long-term debt instruments  contain provisions  limiting the
amount of cash dividends the Company can pay.

DISTRIBUTION The Shares may be sold from time to time by the Selling Shareholders or by pledgees, donees, transferees or other successors in interest. Such sales may be made in any one or more transactions (which may involve block transactions) in the over-the-counter market, on NASDAQ, and any exchange in which the Common Stock may then be listed, or otherwise in negotiated transactions or a combination of such methods of sale, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The Selling Shareholders may effect such transactions by selling Shares to or through broker-dealers, and such broker-dealers may sell the Shares as agent or may purchase such Shares as principal and resell them for their own account pursuant to this prospectus. Such broker-dealers may receive compensation in the form of underwriting discounts, concessions or commissions from the Selling Shareholders and/or purchasers of Shares from whom they may act as agent (which compensation may be in excess of customary commissions). The Company has informed the Selling Shareholders that the anti-manipulative rules under the Securities Exchange Act of 1934 (Regulation M) may apply to their sales of Shares in the market. Also, the Company has informed the Selling Shareholders of the need for delivery of copies of the Prospectus in connection with any sale of securities registered hereunder in accordance with applicable prospectus delivery requirements. In connection with such sales, the Selling Shareholders and any participating brokers and dealers may be deemed to be "underwriters" as defined in the Securities Act. In addition, any of the Shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this Prospectus. In order to comply with certain state securities, laws, if applicable, the Common Stock will not be sold in a particular state unless such securities have been registered or qualified for sale in such state or an exemption from registration or qualification is available and complied with. LEGAL MATTERS The validity of the issuance of the shares of the Common Stock offered hereby will be passed upon for the Company by Charles W. Sprague, Esq., Executive Vice President, General Counsel and Secretary of the Company.

The following table sets forth the various expenses in connection with the sale and distribution of the securities being registered, other than underwriting discounts and commissions.

Item Amount ---- ------ SEC registration fee $7,109.45 NASDAQ listing fee 2,000.00 Legal fees and expenses 1,000.00 Accounting fees and expenses 2,000.00 Miscellaneous 1,090.55 ========== Total $13,200.00 ========== ITEM 15. 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 other cases, the Wisconsin statute 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. 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 it 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 Corporation 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 undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Act, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act), 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. Insofar as indemnification for liabilities arising under the Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 15 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue. The undersigned Registrant hereby further undertakes that: (1) For purposes of determining any liability under the Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Act shall be deemed to be part of this registration statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Act, each post-effective amendment that contains a form of prospectus 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. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Amendment No.1 to the Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Brookfield, State of Wisconsin, on the 16th day of May 1997.

Dear Sirs:

relating to the proposed  resales of up to 631,951  shares of its Common  Stock,
$.01 par value (the "Shares"), by certain Selling Shareholders.

         In that connection,  I have examined originals,  or copies certified or
otherwise  identified to our satisfaction of such documents,  corporate  records
and other  instruments as I have deemed necessary or appropriate for purposes of
this opinion, including the Articles of Incorporation,  as amended, and By-Laws,
as amended, of Fiserv.

         Based upon the foregoing, I am of the opinion that:

         1. The  Company  has been  duly  organized  and is  validly  existing
            as a  corporation  under  the laws of the State of Wisconsin.

         2. The Shares  have been duly authorized  and are validly issued
            and fully paid and nonassessable.

Registration  Statement and to the reference to me under "Legal  Matters" in the
Prospectus  comprising  a part of the  Registration  Statement.  By  giving  the
foregoing  consent,  I do not admit that I come  within the  category of persons
whose consent is required under Section 7 of the Act.

Very truly yours,
