Provided BISYS has satisfied the milestones for years 1 through 3 and that OSI
has satisfied its obligations pursuant to sections 7, 9, 10 and 11 hereof, then
BISYS agrees that the number of conversions for Year 4 and Year 5 shall be 22
and 25, respectively, and further agrees to a Minimum Required License &
Maintenance Fees pursuant to Sections 8(a) and (b) for Years 4 and 5 at amounts
to be mutually agreed that represent the retail sales rates and corresponding
fees of OSI in effect at such time. It is the intent of the parties to evaluate
the terms of this Agreement at the end of such five-year period, including the
extension thereof. The foregoing notwithstanding, OSI shall not have the right
to convert such rights to nonexclusive where BISYS has (i) entered into new
Outsourcing Services and/or Facilities Management agreements with Financial
Institutions representing at least [**] of the number required above for the
periods indicated and (ii) achieved or prepaid the above required minimum
License and Maintenance Fees within 30 days of the end of each annual period.
Provided OSI is not in breach of its obligations under this Agreement, BISYS
shall pay the minimum required fees for the periods indicated above to OSI
(i.e., a total of [**]) in consideration of the exclusivity agreement. Any
amounts paid by BISYS to OSI to satisfy the foregoing minimum obligations and
not otherwise due pursuant to Sections 8(a) and 8(b) hereof shall be treated as
prepaid License and Maintenance Fees under such Sections and shall be applied as
a credit against future amounts due and owing thereunder.

(b)   From the date hereof, BISYS shall be the preferred Facilities Manager for
a licensed System installed at a Financial Institution's facilities (i.e., where
the Financial Institution has been granted a license to use the System in-house
at its facilities and elects to seek a Facilities Manager to operate the
System). Notwithstanding the foregoing, no provision in this agreement shall be
construed as prohibiting a Financial Institution licensed to use the System from
independently retaining a Named Competitor or Excluded Licensee to serve as its
Facilities Manager.



(c)   OSI represents and warrants as of the Effective Date that it has not
granted any license for use of the System to provide Outsourcing Services or to
serve as Facilities Manager to any entity other than BISYS. Unless specifically
prohibited by contract, OSI will provide written notice to BISYS upon the grant
of any license permitted pursuant to the foregoing subparagraph (a). In
addition, OSI agrees to provide an annual certification from its independent
auditors on or before the date it files such financial statements with the
Securities and Exchange Commission and otherwise the 120th day following the end
of each of its fiscal years, in conjunction with issuance of its annual
financial statements, identifying all license grants made pursuant to
subparagraph (a) in effect as of the end of such fiscal year.

(d)   MOST FAVORED CUSTOMER. OSI represents and warrants that all prices,
warranties, benefits and other terms being provided hereunder are equivalent to
or better than the terms being offered by OSI to other similarly situated
entities under similar circumstances. If, during the term of this Agreement,
OSI enters into a licensing agreement with a Permitted Licensee pursuant to and
in  accordance with subparagraph (a) hereof providing such entity with more
favorable terms, then this Agreement will be deemed appropriately amended to
provide such terms to BISYS, and OSI shall promptly provide BISYS with any
refunds or credits thereby created; if applicable, calculated from the
affective date of such other agreement(s).

(e)   EQUITY INVESTMENT. As a condition of the grant of exclusivity and as a
condition to any license grant by OSI to a Permitted Licensee hereunder, BISYS
and OSI shall complete the documentation necessary for BISYS to make, and BISYS
shall promptly thereupon make, the equity investment in OSI described in
Schedule 4(e) to this Agreement.

(f)   REASONABLE COMMERCIAL EFFORTS & NON-COMPETE. BISYS shall use reasonable
commercial efforts in seeking agreements to provide Outsourcing Services and
services as Facilities Manager utilizing the System. Based on OSI's efforts
pursuant to Sections 7, 9, 10 and 11 hereunder, BISYS would expect to convert
an existing T0TALPLUS(TM) system host based client to the System within 12
months of the Effective Date. Successful achievement of this conversion
within the expected time frame is expected to facilitate the development and
refinement of related conversion programs, completion of required development
and the integration into the System of the BISYS provided "wrap-around"
products and services identified in the following Section 5. BISYS agrees to
provide an annual certification from its independent auditors, on or before
such time as it files its

                                      7

<PAGE>

annual financial statements with the Securities and Exchange Commission,
certifying as to the BISYS Customers that entered into Outsourcing Services
or Facilities Management agreements with BISYS during the prior fiscal year.
BISYS recognizes that it is in the parties' best interest that the reputation
of the System be upheld and, accordingly, it shall make commercially
reasonable efforts to provide quality sales and service to its Customers.
Notwithstanding the above and without limiting BISYS right to provide its
host-based T0TALPLUS(R) system outsourcing solution, BISYS shall utilize OSI
as the exclusive provider of client/server core data processing for BISYS
during the term of this agreement. This includes development of a
client/server core processing system by BISYS or the purchase of another
product from an OSI Named Competitor as identified in Section 1.11. A breach
of the foregoing shall be deemed a material breach under the Agreement. BISYS
shall have the opportunity to cure any such breach upon notice as provided in
Section 21 herein.

5.    PREFERRED PROVIDER.

OSI shall include BISYS, and its affiliates, as a recommended preferred provider
to deliver the following additional wrap-around services to OSI direct customers
of the System and as applicable to prospective customers:

(a)   ATM/debit card processing.
(b)   Imaging services (including check and remittance imaging) through
      Document Solutions, Inc., as long as this company is owned by BISYS.
(c)   Tele-services (e.g. loan and mortgage information and application
      processes via telecommunication [phone/internet]) through BISYS
      Creative Solutions, Inc. as long as this company is owned by BISYS.
(d)   LAN/WAN services (e.g. design, implementation, consulting, program
      services, server, workstation and network monitoring).

Unless inappropriate, OSI marketing and promotional material identifying
wrap-around services shall identify BISYS as a recommended preferred provider of
the foregoing services.

6.    SALES AND MARKETING.

(a)   TRAINING. OSI shall provide four weeks advance notice of its regularly
scheduled and periodic special internal sales training programs as well as any
other internal training programs for sales and product support, customer
service personnel and systems and software engineers. BISYS shall have the
right to include a reasonable number of its like employees in such training
programs, subject to class-size limitations, on a no-fee basis. BISYS shall be
responsible for the costs of all training materials and other out-of-pocket
costs and expenses directly or indirectly resulting from the participation of
its employees in such training programs as well as all travel and related
costs.

          Confidential portions omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.

                                      8

<PAGE>

(b)   TRADE SHOWS. OSI and BISYS shall provide each other with advance notice of
their scheduled participation or intent to participate in a trade show so that
the parties may jointly participate if so desired.

(c)   DEMONSTRATION. Upon execution of this Agreement, OSI shall provide to
BISYS a copy of OSI's demonstration program for sales and demonstration purposes
and shall provide BISYS with the most current version of such demonstration
program as it may exist from time to time. Unless inappropriate, OSI
demonstration systems demonstrating "wrap-around" services, as described in
Section 5 hereof, shall demonstrate the "wrap around" services offered by BISYS,


(d)   MARKETING MATERIALS. BISYS and OSI shall, promptly following execution of
this Agreement, develop joint marketing material and standard disclosure
relating to each other, the alliance formed hereby and the products and services
to be offered hereunder, that may be used by both parties on an ongoing
unrestricted basis until otherwise agreed. Such material may also include a new
trademark or logo to reflect the alliance. Prior to the development of such
materials, neither party may publish and distribute any materials using the
trade marks or trade names of the other without the prior written consent of the
other, which shall not be unreasonably withheld. OSI will have final approval of
all marketing materials that represent the material functional aspects of the
System. The parties also expect to engage in certain joint sales and marketing
efforts as mutually agreed. Notwithstanding the foregoing, each party reserves
the right to continue to produce non-referencing marketing materials for their
independent use.

(e)   SALES SUPPORT. OSI agrees to participate directly in any sales and
marketing presentations to potential Customers and to otherwise be actively
involved in providing sales support to BISYS through the period until BISYS has
entered into Outsourcing Services agreements or Facilities Management services
agreements for its first five Customers. Thereafter, upon BISYS' reasonable
request, and subject to availability OSI shall provide appropriate sales support
to assist BISYS in its efforts to execute additional Outsourcing Services
agreement employing the System with potential Customers. BISYS shall be
responsible for the reasonable out-of-pocket costs incurred by OSI for such
support.

(f)   LEAD REGISTRATION AND REFERRAL. Where either BISYS or OSI determines
after a customer sales presentation or other qualification process that the
customer has a legitimate interest in the System being provided in the mode
offered by the other (i.e., in an Outsourcing Services or Facilities
Management mode by an OSI customer prospect or in an in-house mode by a BISYS
customer prospect), such party ("Referring Party") shall provide a written
lead registration and referral notice to the other identifying the potential
customer and contact person. The party receiving the notice shall have the
right to call upon that customer either separately or together with the
Referring Party to close the sale. The parties recognize that they may
continue in competition for such business opportunity. Where the party
receiving the notice (i) has not made a sales presentation to the identified
customer within the six-month period prior to receipt of such notice and (ii)

                                      9

<PAGE>

within six months after the notice enters into an agreement with such
customer to provide the System, the Referring Party shall be entitled to the
Referral Fee described in Section 8 hereof.

Other than the lead registration and referral process described in the foregoing
paragraph, neither party shall have an obligation to disclose to the other nor
shall either party be entitled to information relating to the potential
prospects of the other.

(g)   NOTICE OF AGREEMENTS WITH CUSTOMERS. BISYS shall provide written notice
of a new Financial Institution client using the System to OSI within 30 days of
the execution of an agreement with such new client.

(h)   PRESS RELEASES. The parties expect to issue a mutually agreed upon joint
press release announcing the alliance formed under this Agreement at the
appropriate time. Prior to such public announcement, neither party shall make
any public disclosure of the existence or terms of this Agreement without the
prior written consent of the other.

7.    CONVERSION AND PRODUCTION SUPPORT.

OSI shall provide the Conversion, programming, operations and training resources
necessary to convert the first three Outsourcing Services Customers in
cooperation with BISYS who shall retain control of the Customer interface. In
consideration of such support, BISYS shall reimburse OSI at cost for reasonable
expenses it incurs in connection therewith. OSI shall prepare the Conversion
plans and provide a copy to BISYS. BISYS shall participate in the Conversions as
a training mechanism and shall be responsible for all subsequent Conversions. At
BISYS' reasonable request, and subject to availability, OSI shall provide
assistance for subsequent Conversions and related production. BISYS shall pay
OSI for such subsequent support services based on OSI's time and materials [**].
In addition, OSI shall provide the technical and operations support required to
establish a production environment at BISYS' initial Outsourcing Services
production facility for the System. At a minimum, OSI shall provide the support
required to deliver production for the initial Conversion from the date of such
Conversion through the 30 days post-Conversion. BISYS shall reimburse OSI its
reasonable out-of-pocket costs for such initial production support. Thereafter,
upon BISYS' request, OSI shall provide additional production/technical support
following such 30-day period and for additional Conversions, and in

OSI shall use reasonable commercial efforts to maintain the System competitive
in its marketplace. A breach of the foregoing shall be deemed a material breach
under the Agreement. OSI shall have the opportunity to cure any such breach
upon notice as provided in Section 21 herein. Appropriate representatives of
OSI and BISYS shall meet at least semi-annually to discuss and review OSI
product development plans and for BISYS to provide input based on competitive
feature and function requirements. At any time during the term of this
Agreement, BISYS shall have the right to request certain development efforts
related to the System. To the extent it is mutually agreed that such
development efforts enhance the overall value, marketability or competitive
position of the system, such efforts shall be funded by OSI. BISYS shall be
given the opportunity to contribute to such efforts either through funding
and/or contribution of application specifications and/or certain technology to
expedite delivery or to address certain customer requirements that may not be
considered to significantly enhance the overall value, marketability or
competitive value of the system. In the event that BISYS develops and offers to
OSI an application mutually agreed to have value to the System, BISYS shall
contribute such application to OSI in consideration of a payment equal to the
lesser of 25% of the development costs of BISYS and $250,000. Payment to BISYS
for any such development shall be made quarterly over a three year period. All
products, derivative works or other intellectual property resulting from such
development efforts and incorporated into the System shall, as incorporated, be
the property of OSI regardless of the manner of funding and regardless of
whether made by OSI or BISYS. As the developer of the System, OSI acknowledges
that it will from time to time engage in certain software and hardware
benchmarking activities. OSI shall provide BISYS with written copies of the
results of all such benchmarking activities within 30 days of any such
benchmarking.

The parties recognize that BISYS has an interest in evaluating the technical
feasibility of integrating certain OSI System modules as replacements and/or
upgrades to its existing mainframe modules or otherwise developing linkages
between the OSI System modules and its mainframe modules. OSI agrees to support
and participate in any such feasibility evaluations which are expected to
include an evaluation of the integration of OSI's client server module to the
BISYS mainframe environment and/or use of the OSI System application code at the
BISYS mainframe level.


OSI, recognizing that modifications to the System designed to enhance its
performance in a multi Financial Institution processing environment will be
beneficial I to BISYS and to the Permitted Licensees and are fundamental to
such persons serving as Outsourcing providers, shall modify the System
accordingly to attain the anticipated benefits within a mutually agreeable
time-frame provided that BISYS pays for 75% of the required investment. BISYS
shall recover from OSI up to one-third of such investment(s) (i.e., 25% of the
total investment such that if fully recovered OSI and BISYS shall have each
invested 50% of the required investment) in the following manner:

(a)   upon the grant of a license to a Permitted Licensee, a credit toward
License and Maintenance Fees payable pursuant to Sections 8(a) and (b) hereof
equal to the total investment made by BISYS multiplied by a fraction the
numerator of which is the number

                                      14

<PAGE>

of clients for which the Permitted Licensee provides outsourcing services and
the denominator is the number of clients for which BISYS provides outsourcing
services; and

(b)   a credit of 50% toward any License and Maintenance Fees payable in excess
of the minimum required License and Maintenance Fees pursuant to Sections 8(a)
and (b) hereof as set forth in the table in Section 4(a) hereof.

OSI reserves all right to determine the scope and nature of any and all
development activities that will be performed to the System regardless of the
source of funding.

reasonable commercial efforts to deliver a feasibility assessment with respect
to such additional features, functionality or interfaces in writing within 30
days of receipt of a written request, including but not limited to an assessment
of the time period and resources necessary for, and remuneration to OSI to
satisfy such requirements. Based on such assessment, OSI and BISYS by mutual
agreement shall determine the appropriate course of action to address the
Customer requirements and, if appropriate, to set forth the specifications,
deliverables and costs in a writing mutually agreed and signed by OSI and BISYS.
OSI shall use commercially reasonable efforts to satisfy the requirements set
forth in such written agreement within the agreed time periods. BISYS shall not
make any contractual obligations with respect to such Customer requirements
except as specifically approved in writing by OSI.



12.   THIRD PARTY PRODUCTS.

Subject to limitations with the agreements between OSI and third parties and
applicable law, OS shall split with BISYS on a 50/50 basis all net profit from
the sale of certain third party products, including but not limited to the TPS,
licensed or sold in conjunction with the System to support outsourcing Services
and Facilities Management services provided by BISYS.

(a)   INDEMNIFICATION BY OSI. OSI shall defend, indemnify and hold BISYS and its
officers, directors, agents and employees harmless from and against any and all
claims, suits, damages, liabilities, costs and expenses (including reasonable
attorney's fees) arising out of or resulting from any claim that BISYS' use of
the OSI Proprietary Software or OSI Interface Software infringes a presently
existing United States patent, copyright, or trademark or misappropriates a
trade secret of any third party, provided OSI is:

i)    promptly notified of any and all threats, claims and proceedings related
thereto,
ii)   given reasonable assistance (at OSI's sole cost and expense), and
iii)  given the opportunity to assume sole control over the defense and all
negotiations for a settlement or compromise.

OSI shall not, however, enter into any settlement without BISYS' prior written
consent, which shall not be unreasonably withheld, if such settlement impairs
any material right of BISYS under the Agreement.

Notwithstanding anything to the contrary contained herein, BISYS shall have the
right to defend and settle, at OSI's expense, against any such infringement or
misappropriation claim in the event that OSI fails to assume or reasonably
pursue such defense.

In the event that the OSI Proprietary Software or OSI Interface Software, or any
portion thereof becomes the subject of a claim of infringement or
misappropriation, OSI may, at

                                      20

<PAGE>

its option and its expense, take any of the following steps so that BISYS'
use is not subject to any claim of infringement or misappropriation and BISYS
is provided with functionally equivalent software to the reasonable
satisfaction of BISYS, provided that BISYS' use of the OSI Proprietary
Software or OSI Interface Software conforms with the provisions of the
Agreement:

i)    procure for BISYS the right to continue using the OSI Proprietary Software
or OSI Interface Software; or
ii)   replace or modify the infringing portion of the OSI Proprietary Software
or OSI Interface Software.

The foregoing obligations of OSI do not apply with respect to software and any
other products or portions or components thereof.

i)    which are not the latest available release supplied by OSI to BISYS,
ii)   which are modified by BISYS after shipment by OSI, if the alleged
infringement relates to such modification, unless OSI has consented to the
modification in writing, or such modifications is otherwise authorized,
permitted or provided for under this Agreement, or
iii)  which are combined with other products, processes, hardware or materials
where the alleged infringement relates to such combination, unless OSI has
consented in writing to such combination or such combination is otherwise
authorized, permitted or provided for under this Agreement.

THE FOREGOING STATES THE ENTIRE LIABILITY OF OSI WITH RESPECT TO INFRINGEMENT OF
ANY PATENTS, COPYRIGHTS, TRADEMARKS OR MISAPPROPRIATION OF TRADE SECRETS BY THE
OSI PROPRIETARY SOFTWARE OR OSI INTERFACE SOFTWARE OR ANY PARTS THEREOF. NO
COSTS OR EXPENSES SHALL BE INCURRED FOR THE ACCOUNT OF OSI BY BISYS OR ITS
AGENTS WITHOUT THE PRIOR WRITTEN CONSENT OF OSI.

The provisions of this Section 19 do not apply to any TPS or any OSI Interface
Software licensed by OSI from a third party.

INDEMNIFICATION PROCEDURES. The OSI indemnification obligation under the
foregoing subparagraph (a) shall not apply (I) to the extent that BISYS was
responsible for giving rise to the matter upon which the claim for
indemnification is based, and (ii) unless BISYS promptly notifies OSI of any
matters in respect of which the indemnity may apply and of which BISYS has
knowledge and gives OSI the full opportunity to control the response thereto and
the defense thereof, including without limitation any agreement relating to the
