(1) This Registration Statement shall also cover any additional shares of Common
Stock that become issuable in connection with the shares registered hereby by
reasons of any stock dividend, stock split, recapitalization or other similar
transaction effected without the receipt of consideration that results in an
increase in the number of the Company's outstanding shares of Common Stock.


     (2) On March 12, 2001, the Registrant filed the Registration Statement on
Form S-3 to register 29,245 shares of Common Stock and paid a registration fee
of $380.00 based on a proposed maximum offering price of $1,502,462, or $51.375
per share, which was the average of the high and low sale prices of Common Stock
reported on the Nasdaq National Market on March 7, 2001. This Amendment to the
Registration Statement registers an additional 442,602 shares of Common Stock.
The proposed maximum offering price per share and proposed maximum aggregate
offering price of those additional shares are estimated in accordance with Rule
457(c) solely for the purpose of calculating the additional registration fee
based on a price of $ 46.61 per share, which was the average of the high and low
sale prices of Common Stock on the Nasdaq National Market on April 24, 2001.


(3) Prior to the occurrence of certain events, purchase rights for Common Stock
will not be evidenced separately from the Common Stock.

     THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL

STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF

         We were organized in August 1989 to acquire certain banking and thrift

traditional business was established in 1966 by United Data Processing, Inc.,
the predecessor of the banking and thrift data processing operations of ADP.
Together with our predecessors, we have provided outsourcing solutions to the

                                  RISK FACTORS

         You should carefully consider the following risk factors, together with
the other information in this Prospectus, before you make a decision on whether
to purchase any shares of common stock offered by this Prospectus.

         This Prospectus contains forward-looking statements. These statements
are identified by words like "believe", "will", "intend", "expect", "should",
"could", "anticipate", "estimate" and "project". Our actual results could differ
materially from these statements due to risks and uncertainties, including the
ones described below:

                          RISKS RELATED TO OUR BUSINESS

THE FINANCIAL SERVICES MODERNIZATION ACT OF 1999 COULD ADVERSELY IMPACT OUR
BUSINESS BY EXPANDING THE POWERS OF OUR BANKING CLIENTS AND REDUCING THEIR
OUTSOURCING.

         The adoption of the Financial Services Modernization Act of 1999
repeals key provisions of the Glass-Steagall Act and lifts many restrictions
limiting banks from the underwriting and distribution of securities. As a
result of these regulatory changes, we expect that some of our bank customers
with proprietary mutual funds may, over time, internalize certain distribution
functions that we currently provide. If that were to happen, it could have a
material adverse impact on our business and results of operations.

OUR BUSINESS CAN BE SIGNIFICANTLY AFFECTED BY DIRECT AND INDIRECT GOVERNMENTAL
REGULATION, WHICH REDUCES OUR FLEXIBILITY AND INCREASES THE COSTS OF DOING
BUSINESS.

         Our business is affected by federal, state and foreign regulations. Our
noncompliance with these regulations could result in the suspension or
revocation of our licenses or registrations, including broker/dealer licenses
and registrations and insurance producer licenses and registrations. Regulatory
authorities could also impose on us civil fines and criminal penalties for
noncompliance.

         Some of our subsidiaries are registered with the Securities and
Exchange Commission as broker-dealers. Much of the federal regulation of
broker-dealers has been delegated to self-regulatory organizations, principally
the National Association of Securities Dealers, Inc. and the national
securities exchange. Broker-dealers are subject to regulations which cover all
aspects of their securities business, including, for example:

                                       5
   8
                  -        sales methods;

                  -        trading practices;

                  -        use and safekeeping of customers' funds and
                           securities;

                  -        capital structure;

                  -        recordkeeping; and

                  -        the conduct of directors, officers and employees.

The operations of our broker-dealers and their profitability could be affected
by:

                  -        federal and state legislation;

                  -        changes in rules and regulations of the SEC, banking
                           and other regulatory agencies, and self-regulatory
                           agencies; and

                  -        changes in the interpretation or enforcement of
                           existing laws, rules and regulations.

         Banks and other depository institutions with whom we do business are
also subject to extensive regulation at the federal and state levels under laws
and regulations applicable to regulated financial institutions. They are also
subject to extensive examination and oversight by federal and state regulatory
agencies. Changes in the laws, rules and regulations affecting our client banks
and financial institutions and the examination of their activities by applicable
regulatory agencies could adversely affect our results of operations.

         Some of our subsidiaries, and officers and employees of these
subsidiaries, are required to be licensed as insurance producers in various
jurisdictions in which we conduct our insurance services business. They are
subject to regulation under the insurance laws and regulations of these
jurisdictions. Changes in the laws, rules and regulations affecting licensed
insurance producers could adversely affect our operations.

OUR REVENUES AND EARNINGS ARE SUBJECT TO CHANGES IN THE SECURITIES MARKET.

         A significant portion of our earnings are derived from fees based on
the average daily market value of the assets we administer for our clients. A
sharp rise in interest rates or a sudden decline in the securities market could
influence an investor's decision whether to invest or maintain an investment in
a mutual fund. As a result, fluctuations could occur in the amount of assets
which we administer. If investors were to seek alternatives to mutual fund
investments, it could have a negative impact on our revenues by reducing the
amount of assets we administer.

                                       6
   9
CONSOLIDATION IN THE BANKING AND FINANCIAL SERVICES INDUSTRY COULD ADVERSELY
IMPACT OUR BUSINESS BY ELIMINATING THE NUMBER OF EXISTING AND POTENTIAL CLIENTS.

         There has been and continues to be merger, acquisition and
consolidation activity in the banking and financial services industry. Mergers
or consolidations of banks and financial institutions in the future could reduce
the number of our clients or potential clients. A smaller market for our
services could have a material adverse impact on our business and results of
operations. Also, it is possible that the larger banks or financial institutions
which result from mergers or consolidations could decide to perform themselves
some or all of the services which we currently provide or could provide. If that
were to occur, it could have a material adverse impact on our business and our
results of operations.

OUR ACQUISITION STRATEGY SUBJECTS US TO RISKS, INCLUDING INCREASED DEBT,
ASSUMPTION OF UNFORESEEN LIABILITIES AND DIFFICULTIES IN INTEGRATING OPERATIONS.

         In the past several years, we have acquired a number of other
companies. We may make additional acquisitions. We cannot predict if or when any
additional acquisitions will occur or whether they will be successful.

         Acquiring a business involves many risks, including:

                  -        incurrence of debt;

                  -        incurrence of unforeseen obligations or liabilities;

                  -        difficulty in integrating the acquired operations and
                           personnel;

                  -        difficulty in maintaining uniform controls,
                           procedures and policies;

                  -        possible impairment of relationships with employees
                           and customers as a result of the integration of new
                           personnel;

                  -        risk of entering markets in which we have minimal
                           prior experience;

                  -        decrease in earnings as a result of non-cash charges;
                           and

                  -        dilution to existing stockholders from the issuance
                           of our common stock to make or finance acquisitions.

OUR SYSTEMS MAY BE SUBJECT TO INFILTRATION BY UNAUTHORIZED PERSONS.


         We maintain and process data on behalf of our clients, some of which is
critical to the business operations of our clients. For example, our Information
Services Group maintains account information for our bank and insurance company
clients it services and our Investment Services Group maintains transfer agency
records and processes trades for our mutual fund clients. If our systems were
infiltrated and damaged by unauthorized persons, our clients could experience
data loss, financial loss and significant business interruption. If that were to
occur, it could have a material adverse effect on our business, financial
condition and results of operations.


WE FACE SIGNIFICANT COMPETITION FROM OTHER COMPANIES.

         We face significant competition from other companies. Many of our
competitors are well-established companies, and some of them have greater
financial, technical and operating resources than we do. Competition in our
business is based primarily upon pricing, quality of products and services,
breadth of products and services, new product development and the ability to
provide technological solutions.


WE DEPEND ON KEY MANAGEMENT PERSONNEL, MOST OF WHOM DO NOT HAVE LONG-TERM
EMPLOYMENT AGREEMENTS.


         Our success depends upon the continued services of our key senior
management personnel including our executive officers and the senior managers of
our businesses. None of our executive officers have employment agreements with
us and substantially all of our other senior management personnel do not have
employment agreements with us. The loss or unavailability of these individuals
could have a material adverse effect on our business prospects.



WE DEPEND ON OUR ABILITY TO ATTRACT AND RETAIN SKILLED PERSONNEL.



         Our success depends on our ability to attract and retain highly
skilled personnel in all areas of our business, including our information
processing, fund management and insurance services businesses. We cannot assure
that we will be able to attract and retain personnel on acceptable terms in the
future. Our inability to attract and retain highly skilled personnel could have
an adverse effect on our business prospects.


                       RISKS RELATED TO OUR COMMON STOCK

WE DO NOT INTEND TO PAY DIVIDENDS.

         We have never paid cash dividends to stockholders and do not anticipate
paying cash dividends in the foreseeable future. In


                                       8
   11
addition, our existing credit facility limits our ability to pay cash dividends.

OUR STOCK PRICE HAS BEEN AND IS LIKELY TO CONTINUE TO BE VOLATILE.

         The market price of our common stock has been volatile. From January 1,
1999 to April 24, 2001, the last sale price of our common stock ranged from a
low of $20.98 per share to a high of $56.88 per share.




FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE.

         Sales of a substantial number of shares of our common stock in the
public market, or the appearance that such shares are available for sale, could
adversely affect the market price for our common stock. As of February 23, 2001,
we had 57,440,316 shares of common stock outstanding. As of February 23, 2001,
we also had options to purchase 7,225,247 shares of our common stock outstanding
and 4,351,208 shares of our common stock reserved for issuance pursuant to
options available for issuance under our stock option plans and employee stock
purchase plan.

ANTI-TAKEOVER EFFECTS OF CERTAIN BY-LAW PROVISIONS, DELAWARE LAW, AND OUR
SHAREHOLDER RIGHTS PLAN COULD DISCOURAGE, DELAY OR PREVENT A CHANGE IN CONTROL.

         We have a shareholder rights plan. Under the plan, each holder of
shares of our common stock will receive a right to buy one share of our common
stock at an exercise price of $175. If a person or group were to acquire, or to
announce the intention to acquire, 15% or more of our outstanding shares of
common stock, and in some cases 10%, each right would entitle the holder, other
than the acquiring person or group, to purchase shares of our common stock at
the exercise price of the right with a value of twice the exercise price. This
plan could have the effect of discouraging, delaying or preventing persons from
attempting to acquire us.

                                       9
   12
         In addition, the Delaware General Corporation Law, to which we are
subject, prohibits, except under circumstances specified in the statute, a
corporation from engaging in any mergers, significant sales of stock or assets
or business combinations with any stockholder or group of stockholders who own
at least 15% of our common stock.


                                 USE OF PROCEEDS


         We will not receive any of the proceeds from the sale of the shares
offered in this Prospectus. All of the proceeds from the sale of the shares will
be paid directly to the selling stockholders.



                              SELLING STOCKHOLDERS



                  All of the shares offered by this Prospectus are to be sold
for the account of the selling stockholders shown below.



                  Bruce Andrew Harrison, a selling stockholder, is the former
sole stockholder of P. J. Robb Variable Corp. In connection with our acquisition
of P. J. Robb Variable Corp., he represented to us that he was acquiring shares
of our common stock without any present intention of effecting a distribution of
those shares and agreed that he would not sell or otherwise dispose of the
shares other than pursuant to an effective registration statement under the
Securities Act or pursuant to an exemption from the registration requirements of
the Securities Act.



                 The other selling stockholders are the former stockholders of
Boston Institutional Group, Inc. In connection with our acquisition of Boston
Institutional Group, Inc., they represented to us that they were acquiring
shares of our common stock without any present intention of effecting a
distribution of those shares and agreed that they would not sell or otherwise
dispose of the shares other than pursuant to an effective registration statement
under the Securities Act or pursuant to an exemption from the registration
requirements of the Securities Act.



                  We granted registration rights to the selling stockholders
under registration rights agreements between the stockholders and us, because
they wish to be able to sell some or all of their shares when they deem it
appropriate.



                  We agreed to file at our expense a registration statement with
the SEC covering the shares held by the selling stockholders and to use our best
efforts to keep the registration statement effective (a) in the case of Mr.
Harrison, until the earlier to occur of the sale of all of his shares covered by
the registration statement or March 1, 2002, which is the first anniversary of
the effective date of our acquisition of P. J. Robb Variable Corp. and (b) in
the case of the former stockholders of Boston Institutional Group, Inc., until
the earlier to occur of the sale of all of their shares covered by the
registration statement or April 11, 2002, which is the first anniversary of the
effective date of our acquisition of Boston Institutional Group, Inc. We will
prepare and file at our expense any amendments and/or supplements to the
registration statement as may be necessary until all of the shares have been
sold pursuant to the registration statement or until our registration
obligations have ended.



         The following table sets forth information, as of the date of this
Prospectus, with respect to the selling stockholders:

                              PLAN OF DISTRIBUTION


         We are registering the shares for the selling stockholders. As used
herein, "selling stockholders" includes donees or pledgees selling shares
received from a selling stockholder after the date of this Prospectus and
persons selling shares received from a selling stockholder after the date of
this Prospectus by will or the laws of descent and distribution. We will bear
all costs, expenses and fees in connection with the registration of the shares
offered hereby. The selling stockholders will be responsible to pay brokerage
commissions and similar selling expenses, if any, attributable to the sale of
shares.



         The selling stockholders may offer and sell their shares at various
times in one or more of the following transactions:


         -        on the Nasdaq National Market;

         -        in the over-the-counter market;

         -        in negotiated transactions;

         -        through short sales of shares;

         -        through put or call transactions; or

         -        in a combination of any of the above transactions.


         The selling stockholders may sell their shares at market prices
prevailing at the time of sale or at negotiated prices.



         The selling stockholders may effect transactions by selling shares
directly to purchasers or to or through broker-dealers, which may act as agents
or principals. Those broker-dealers may receive compensation in the form of
discounts, concessions, or commissions from the selling stockholders and/or the
purchasers of shares for whom those broker-dealers may act as agents or to whom
they sell as principal, or both. The compensation could, as to a particular
broker-dealer, be in excess of customary commissions.



         The selling stockholders may enter into hedging transactions with
broker-dealers or other financial institutions. In connection with those
transactions, broker-dealers or other financial institutions may engage in short
sales of our common stock in the course of hedging the positions they assume
with those selling stockholders. The selling stockholders may also enter into
options or other transactions with broker-dealers or other financial
institutions which require the delivery to those broker-dealers or other
financial institutions of shares offered hereby, which shares the broker-dealers
or other financial institutions may resell pursuant to this Prospectus (as
supplemented or amended to reflect the transactions).



         The selling stockholders and any broker-dealers or agents that act in
connection with the sale of shares may be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act. Any discounts or commissions
received by broker-dealers and any profit on the resale of the shares sold by
them while acting as principals might be deemed to be underwriting discounts or
commissions under the Securities Act.



         We have agreed to indemnify the selling stockholders against certain
liabilities, including liabilities arising under the Securities Act. The selling
stockholders may agree to indemnify any agent, dealer, or broker-dealer that
participates in transactions involving sales of the shares against certain
liabilities, including liabilities arising under the Securities



                                       12
   15

Act. The selling stockholders have agreed to indemnify us against certain
liabilities, including liabilities arising under the Securities Act.



         Because the selling stockholders may be deemed to be an "underwriters"
within the meaning of Section 2(11) of the Securities Act, the selling
stockholders will be subject to the prospectus delivery requirements of the
Securities Act. The selling stockholders may also be subject to the
anti-manipulative provisions of Regulation M under the Securities Exchange Act
as it may apply to their sales in the market. These provisions may limit the
timing of purchases and sales.



         The selling stockholders also may resell all or a portion of their
shares in open market transactions in reliance upon Rule 144 under the
Securities Act, provided they meet the criteria and conform to the requirements
of that Rule.



         If we are notified by a selling stockholder that any material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, distribution or a purchase by a broker
or dealer, a supplement to this prospectus will be filed, if required, pursuant
to Rule 424(b) under the Securities Act, disclosing:



         -        the name of each selling stockholder and of the participating
                  broker-dealer(s);


         -        the number of shares involved;

         -        the price at which shares were sold;

         -        the commissions paid or discounts or concessions allowed to
                  broker-dealer(s), where applicable;

         -        that the broker-dealer(s) did not conduct any investigation to
                  verify the information set out or incorporated by reference in
                  this Prospectus; and

         -        other facts material to the transaction.


         In addition, if we are notified by a selling stockholder that a donee
or pledgee intends to sell more than 500 shares, a supplement to this prospectus
will be filed.


                                  LEGAL MATTERS

         The validity of the shares offered hereby will be passed upon for us by

All of the foregoing estimated expenses are being borne by The BISYS Group, Inc.
(the "Registrant").

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The Registrant is organized under the laws of the State of Delaware.
Section 145 of the Delaware General Corporation Law permits a Delaware
corporation to indemnify any person who is a party (or is threatened to be made
a party) to any threatened, pending or completed action, suit or proceeding
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) by reason of the fact that he or she is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation or enterprise. A corporation may similarly
indemnify such person in the case of actions or suits brought by or in the right
of the corporation, except (unless otherwise ordered by the court) that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation.

         A corporation may indemnify such person against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. Any indemnification shall be made by the corporation only
as authorized in the specific case upon a determination that indemnification is
proper in the circumstances because the person has met the aforesaid



                                      II-1




   18
standard of conduct. Such determination shall be made (1) by a majority vote of
the directors who were not parties to the action, suit, or proceeding, whether
or not a quorum, or (2) if there are no such directors, or if such directors so
direct, by independent legal counsel in a written opinion, or (3) by the
stockholders. To the extent that a director, officer, employee or agent of a
corporation has been successful on the merits, or otherwise, in defense of any
action, suit or proceeding described above, or in defense of any claim, issue or
matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred in connection therewith. The
statute also provides that it is not exclusive of any other rights to which
those seeking indemnification may be entitled under any bylaws, agreement, vote
of stockholders or disinterested directors, or otherwise. The Registrants'
By-Laws provide for the indemnification of its directors and officers to the
fullest extent permitted by law.

         Section 102(b)(7) of the Delaware General Corporation Law allows a
Delaware corporation to limit or eliminate the personal liability of directors
to the corporation and its stockholders for monetary damages for breach of
fiduciary duty as a director. However, this provision excludes any limitation on
liability (1) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (2) for acts or omissions not in good faith or
which involved intentional misconduct or a knowing violation of law, (3) for
intentional or negligent payment of unlawful dividends or stock purchases or
redemptions or (4) for any transaction from which the director derived an
improper benefit. Moreover, while this provision provides directors with
protection against awards for monetary damages for breaches of their duty of
care, it does not eliminate such duty. Accordingly, this provision will have no
effect on the availability of equitable remedies such as an injunction or
rescission based on a director's breach of his or her duty of care. Finally,
this provision applies to an officer of a corporation only if he or she is a
director of such corporation and is acting in his or her capacity as director,
and does not apply to officers of the corporation who are not directors.

         The Registrant's Certificate of Incorporation provides for the
limitation on liability permitted by Section 102(b)(7). The Registrant maintains
directors and officers' liability insurance.

ITEM 17.  UNDERTAKINGS

         (a)      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 percent change
                           in the maximum aggregate 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) do not
apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and
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.

                                      II-4
   21
                  (2) That, for the purpose of determining any liability under
the Securities Act of 1933, 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) 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) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 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 Securities and
Exchange 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.

         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 Township of Little Falls, State
of New Jersey, on April 26, 2001.
