ITEM 1.  BUSINESS

OVERVIEW

     ProBusiness is a leading provider of employee administrative services 
for large employers. The Company's primary service offerings are payroll 
processing, payroll tax filing, benefits administration, including the 
enrollment and processing of flexible benefits plans and COBRA programs, and 
human resources software. The Company's proprietary PC-based payroll system 
offers the cost-effective benefits of outsourcing and high levels of client 
service, while providing the flexibility, control, customization and 
integration of an in-house system. As of June 30, 1998, the Company provided 
services to approximately 1,400 clients. As of June 30, 1998, the Company 
provided payroll processing services to approximately 510 clients with an 
aggregate of approximately 575,000 active employees and an average of 
approximately 1,100 employees. For the quarter ended June 30, 1998, the 
Company processed 4.3 million checks for the Company's payroll clients. In 
addition to providing tax filing services for its payroll clients, as of June 
30, 1998 the Company provided national tax filing services to 72 clients with 
an aggregate of approximately 1.1 million employees and an average of more 
than 15,200 employees. 

     The Company differentiates itself from its competitors through its
proprietary PC-based technology, high quality, responsive and professional
client service, and focus on the needs of large employers. ProBusiness develops
a business partnership with each client by assessing each client's payroll
processing needs, reengineering and designing the client's payroll systems and
processes and implementing a cost-effective solution. The Company maintains an
ongoing relationship with each client using a strategic team of specialists led
by a personal account manager who proactively manages each client's account and
marshals the resources of the team to meet the client's specific needs.
ProBusiness maintains a low client-to-account manager ratio to offer clients
accessible and responsive account management. The Company believes that its low
client-to-account manager ratio and its focus on client service are key factors
in enabling the Company to achieve a high payroll client retention rate, which
was approximately 92% for fiscal year 1998. 

     The Company provides large employers with the cost-effective benefits of 
outsourcing and high levels of client service, while providing the 
flexibility, system control, customization and integration of an in-house 
system. The Company combines its PC-based technology and personalized client 
service to provide a broad range of service offerings, including payroll 
processing, payroll tax filing, benefits administration and human resources 
software. 

     The Company's objective is to be the premier provider of employee
administrative services for large employers. The Company's strategy is to
continue providing clients with high levels of personal service and developing a
comprehensive and fully integrated suite of employee administrative services.
The Company also intends to expand its client base and provide additional
services to its existing clients. 

     The Company was incorporated in California in October 1984 and 
reincorporated in Delaware in September 1997. The Company's executive offices 
are located at 4125 Hopyard Road, Pleasanton, California 94588, and its 
telephone number is (925) 737-3500.

                                       3



SERVICE OFFERINGS

     The Company provides a broad range of employee administrative services,
including payroll processing, tax filing, benefits administration and human
resources software. The Company intends to expand its service offerings through
future acquisitions, alliances and investments and to develop enhancements to
its existing services internally. 

PAYROLL PROCESSING.  The Company processes time and attendance data to calculate
and produce employee paychecks, direct deposits and reports for its clients.
Clients receive paychecks and reports within 24 to 48 hours of the Company's
receipt of the data electronically submitted from the client. The Company's
system is highly configurable to meet the specialized needs of each client yet
maintains the ability to provide high volume processing. The system integrates
easily with the client's general ledger, human resources and time and attendance
systems. In addition, the Company offers many sophisticated features, including
the automatic enrollment and tracking of paid time off, proration of
compensation for new hires and integrated garnishment processing. 

PAYROLL TAX FILING.  The Company collects contributed employer and employee tax
funds from clients, deposits such funds with tax authorities when due, files all
tax returns and reconciles the client's account. The Company will also represent
the client before tax authorities in disputes or inquiries. Substantially all
existing payroll clients utilize the Company's payroll tax service. In addition,
as of June 30, 1998, the Company provided national tax services to 72 clients
with an aggregate of more than 1.1 million employees and an average of more than
15,200 employees. 

BENEFITS ADMINISTRATION.  The Company's benefits administration services include
flexible benefits enrollment and processing, COBRA administration and
consolidated billing and eligibility tracking. Employees can enroll in and
choose their flexible spending benefits through traditional paper-based forms or
through Internet-accessible enrollment sites using the Company's Enrollnet-TM-
service. 

HUMAN RESOURCES SOFTWARE.  The Company's human resources software tracks and 
reports general employee information, including compensation, benefits, 
skills, performance, training, job titles and medical history. For clients 
that also use the Company's payroll service, the human resources data can be 
transferred to the payroll services system, thus eliminating the need for 
duplicate data entry. 

     The Company continually evaluates the addition of add-on service 
offerings to expand the breadth of its solution through alliances, 
acquisitions or internal development. Such additional services include 
administrative services related to time and attendance, travel and 
entertainment, unemployment insurance and 401(k) plans. 

CLIENT SERVICE

     The Company believes that its focus and dedication to providing high levels
of client service is a competitive advantage in the large employer market.
ProBusiness develops a business partnership with each client by assessing each
client's payroll processing needs, reengineering and designing the client's
payroll system and process and implementing a value-added solution. The Company
maintains an ongoing relationship with each client using a strategic team that 



                                          4


includes a sales representative, a sales analyst, an implementation manager, 
an account manager and numerous functional, regulatory and technical support 
specialists. The Company intends to continue providing its clients with a 
high level of service by hiring professionals who are experienced in their 
fields. Most service personnel have experience in payroll, accounting, human 
resources or financial services industries, and many hold Certified Public 
Accountant or Certified Payroll Professional accreditations. 

     The Company continually monitors the quality of its service through client
feedback mechanisms. The Company obtains valuable insights into the needs of its
clients through its partnership with each client and from client responses to
surveys, which are conducted semi-annually. The Company uses this information to
help develop, identify and optimize new service offerings provided to existing
clients and improve the level of service provided to clients. The Company also
uses client feedback as a basis for incentive compensation and recognition of
achievements. 

SALES.  The Company believes that client service begins with the sales process.
A sales representative and a sales analyst work together to assess a potential
client's payroll processing needs. Based on this assessment, the sales team then
identifies opportunities to reengineer the prospective client's payroll
processes and to design a payroll solution that integrates effectively with its
other systems. The payroll sales cycle typically ranges from three to twelve
months or longer. 

IMPLEMENTATION.  Upon engagement by a client, the Company assigns a team of
technical support specialists, headed by an implementation manager who leads the
transition from the client's former payroll system to the Company's system. The
implementation manager works with the client, the sales analyst and technical
support specialists to integrate the Company's payroll system with the client's
other systems and to customize the system to improve the client's payroll
processes. The Company uses its systems integration expertise to facilitate the
integration of its payroll processing system with the client's existing hardware
and software. The implementation process generally takes three to nine months or
longer, depending on the complexity of the client's payroll processes and
systems and the size of the client. 

ACCOUNT MANAGEMENT.  An account manager is assigned to each client during the
implementation process and serves as the client's day-to-day contact at the
Company. The account manager coordinates the efforts of the Company's
functional, regulatory and technical support specialists as necessary. The
account manager visits each client regularly and establishes an annual business
plan with the client that details scheduled payroll events such as open
enrollment periods for employee benefits plans or software system changes. This
annual business plan allows the Company to provide clients with uninterrupted
payroll services during these periods. Account managers use the Company's
proprietary CallLog system to record and track all client calls, record client
feedback and help ensure that the client's needs are addressed promptly and
thoroughly. The Company maintains a low client-to-account manager ratio to offer
clients accessible and responsive account management. 

SUPPORT SPECIALISTS.  The Company supports each client with functional and
regulatory specialists in payroll, payroll tax and employee benefits, as well as
pay data interfaces, general ledger interfaces, paid-time-off, report writing
and system integration. Each of these specialists is available to speak directly
with clients as needed, meet with clients onsite or support clients indirectly
through the account manager. 

TECHNOLOGY

     The Company's proprietary PC-based technology for its payroll services
provides a platform for delivering high levels of service together with the
flexibility and control of an in-house system. The Company creates a mirrored
version of each client's system, which allows the Company's account managers to
access client information using the same data, programs and screens as the
client uses on its PC network. This enables the Company to quickly and easily
identify client problems or modify application programs in response to client
requests. The client maintains control by having direct access to all
calculation programs and all historical and transactional data, which also
provides the client with flexibility to respond quickly to employee and
third-party inquiries, to fully analyze payroll data and to generate management
reports. The Company's intuitive Windows-based interface makes navigation simple
and allows new users to be trained quickly. The Company is developing a new
suite of online self-service administrative services applications accessible 


                                          5


through the Internet that enable clients' employees to view paychecks and other
compensation and benefits data. 

     The Company's system architecture is designed to distribute payroll
processing tasks to multiple low cost, high performance PCs, which enables the
Company to scale its system continually to handle increasing transaction
volumes. The Company's PC-based application software supports the development of
customized solutions for each client that can be easily upgraded and integrated
with a client's other systems. In addition, multiple networked PCs facilitate
exception processing and rapid response that large employers require. 

CLIENTS

     The Company targets large companies with complex and changing business 
needs in diverse industries. As of June 30, 1998, the Company provided 
services to approximately 1,400 clients. Of these clients, approximately 510 
were payroll processing clients, with an aggregate of approximately 575,000 
active employees and an average of approximately 1,100 employees. For the 
quarter ended June 30, 1998, the Company processed 4.3 million payroll checks 
for the Company's payroll clients. The Company began providing national tax 
filing services to clients in 1996 and, as of June 30, 1998, provided these 
services to 72 clients with an aggregate of more than 1.1 million employees 
and an average of more than 15,000 employees. Substantially all existing 
payroll clients utilize the Company's payroll tax filing service. For fiscal 
1998, no client accounted for more than 4% of the Company's revenue

     The Company believes that its low client-to-account manager ratio and its
focus on client service are key factors in enabling the Company to achieve a
high payroll client retention rate, which was approximately 92% for fiscal 1998.
Historically, the Company's client retention rates have been negatively impacted
primarily due to clients ceasing to use the Company's services following a
merger or sale of the client. The Company does not have long-term contracts with
its clients, and the Company's existing contracts do not have significant
penalties for cancellation. 

SALES AND MARKETING

     The Company employs a direct sales force to gain new payroll and payroll
tax clients and increase the number of services provided to existing clients.
The Company currently targets large employers through direct marketing, trade
shows and active participation in local chapters of the American Payroll
Association. The Company uses a team selling approach, whereby sales analysts
and sales representatives collaborate to assess a potential client's needs and
develop a cost-effective solution. The payroll sales cycle typically ranges from
three to twelve months or longer. The Company primarily utilizes insurance
brokers to attract new benefits administration clients. 

     The Company seeks to attract and retain experienced industry sales
representatives. The Company believes that its long-term competitiveness depends
on increasing further its national presence. The Company believes that
continuing to add direct sales representatives in major metropolitan areas
throughout the United States is the most effective means of increasing its
national client base. Over the past two years, the Company has added sales and
implementation representatives covering major metropolitan areas, including
Atlanta, Chicago, Dallas, New York and Seattle. To support its sales growth in
the eastern United States, the Company intends to open a satellite sales and
implementation center in New Jersey during the fourth quarter of calendar 1998. 

     The Company's marketing department provides support materials and marketing
communications to sales representatives, promotes public relations, conducts
direct mail campaigns, manages trade show participation, and develops and
manages corporate Web sites. 

     As part of its strategy to provide a comprehensive suite of employee
administrative services, the Company has recently entered into strategic
alliances with two industry leaders. The Company has formed an alliance with SAP
AG, a leading provider of enterprise business solutions, to offer customers high
levels of flexibility in managing payroll and payroll tax processes by linking
the Company's payroll and tax solution to SAP's HR System. The Company has also
formed an alliance to provide services to clients jointly with Sheakly
UniService, a leading provider of unemployment cost control services. 


                                          6


RESEARCH AND DEVELOPMENT

     The Company intends to continue investing substantial resources to further
develop a comprehensive and fully integrated suite of employee administrative
services and extend the functionality of its proprietary payroll processing
systems. For example, the Company is developing a new suite of online
self-service administrative services applications accessible through the
Internet that enable clients' employees to view paychecks as well as other
compensation and benefits data. In addition, the Company expects to introduce an
integrated payroll and human resources system utilizing client/server technology
that will run on Windows 95 and Windows NT. 

     The foregoing information contains forward-looking statements that involve
risks and uncertainties. Actual events could differ materially from those
anticipated in these forward-looking statements, as a result of certain factors
including those discussed in the paragraph below.

COMPETITION

     The market for the Company's services is intensely competitive, subject to
rapid change and significantly affected by new service introductions and other
market activities of industry participants. The Company primarily competes with
several public and private payroll service providers such as Automatic Data
Processing, Inc., Ceridian Corporation and Paychex, Inc., as well as smaller,
regional competitors. Many of these companies have longer operating histories,
greater financial, technical, marketing and other resources, greater name
recognition and a larger number of clients than the Company. In addition,
certain of these companies offer more services or features than the Company and
have processing facilities located throughout the United States. The Company
also competes with in-house employee services departments and, to a lesser
extent, banks and local payroll companies. With respect to benefits
administration services, the Company competes with insurance companies, benefits
consultants and other local benefits outsourcing companies. The Company may also
compete with marketers of related products and services that may offer payroll
or benefits administration services in the future. The Company has experienced,
and expects to continue to experience, competition from new entrants into its
markets. Increased competition could result in pricing pressures, loss of market
share and loss of clients, any of which could have a material adverse effect on
the Company's business, financial condition and results of operations. 

     The Company believes that the principal competitive factors affecting its
market include client service, system functionality and performance, system
scalability, reputation, system cost and geographic location. The failure of the
Company to compete successfully would have a material adverse effect on the
Company's business, financial condition and results of operations. 

PROPRIETARY RIGHTS

     The Company's success is dependent in part upon its proprietary software
technology. The Company relies on a combination of contract, copyright and trade
secret laws to establish and protect its proprietary technology. The Company has
no patents, patent applications or registered copyrights. The Company
distributes its services under software license agreements that grant clients
licenses to use the Company's services and contain various provisions protecting
the Company's ownership and the confidentiality of the underlying technology.
The Company generally enters into confidentiality and/or license agreements with
its employees and existing and potential clients, and limits access to and
distribution of its software, documentation and other proprietary information.
There can be no assurance that the steps taken by the Company in this regard
will be adequate to deter misappropriation or independent third-party
development of the Company's technology. 

     There can be no assurance that the Company's services and technology do not
infringe any existing patents, copyrights or other proprietary rights or that
third parties will not assert infringement claims in the future. If any such
claims are asserted and upheld, the costs of defense could be substantial and
any resulting liability to the Company could have a material adverse effect on
the Company's business, financial condition 


                                          7


and results of operations.

EMPLOYEES

     As of June 30, 1998, the Company had 500 full-time employees. The Company
believes that its relations with its employees are good. 

ITEM 2. PROPERTIES

     The Company's headquarters are located in Pleasanton, California and 
consist of approximately 130,000 square feet of office space leased through 
September 2008. The Company has signed a lease for a building to be built 
adjacent to its headquarters which will consist of approximately 70,000 
square feet, of which approximately 35,000 square feet is expected to be 
available in mid-1999, and the remaining is expected to be available mid-2000. 

     The Company also has a sales, implementation and production facility and 
a back-up payroll facility in Irvine, California, where it leases 
approximately 14,000 square feet under a lease which terminates May 2002. In 
addition, the Company has a sales office in Kettering, Ohio pursuant to a 
lease which terminates in July 1999. The Company intends to open a satellite 
sales and implementation center in New Jersey. 

     The Company's benefits administration processing operations are located in
Bellevue, Washington, where the Company leases approximately 6,500 square feet
under a lease that will terminate in June 2003. The Company is currently
negotiating a lease for a new building in Bellevue to house the Company's
benefits administration processing operations. Such lease is expected to
commence in early 1999. 

     The Company believes that its existing facilities are adequate for its
current needs and that additional facilities can be leased to meet future needs.

ITEM 3.  LEGAL PROCEEDINGS

     There are no material pending legal proceedings.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS 

     No matter was submitted to a vote of security holders, through the
solicitation of proxies or otherwise, during the fourth quarter of the fiscal
year ended June 30, 1998.

giving effect to the stock split effected on August 7, 1998). Prior to 
September 19, 1997, there was no public trading market for the Common Stock. 



                                                                  High     Low

  FISCAL 1998:
      First Quarter (from September 19, 1997)...............     $12.92   $7.67
      Second Quarter........................................      15.33   12.08
      Third Quarter.........................................      20.00   14.00
      Fourth Quarter........................................      32.58   17.33



     On July 31, 1998, there were 372 holders of record of the Company's Common
Stock. The Company believes that the number of beneficial owners of the Common
Stock is substantially greater than the number of record owners because a large
portion of the Common Stock is held of record in broker "street names." The last
reported sale price per share of the Common Stock on September 21, 1998 on the
Nasdaq National Market was $28.0625.

     (b)  On September 19, 1997, the Company commenced an initial public 
offering, which consisted of 4,312,500 shares of its Common Stock (the 
"Offering") at $7.33 per share pursuant to a registration statement (No. 
333-23189) declared effective by the Securities and Exchange Commission on 
September 19, 1997. As of April 1, 1998, approximately $15.2 million of the 
net proceeds from the Offering were invested in short-term financial 
instruments. From April 1, 1998 to June 30, 1998, the Company used 
approximately $1.4 million of these proceeds from the short-term financial 
instruments, using approximately $1.1 million to repay indebtedness incurred 
in connection with the acquisition of BeneSphere Administrators, Inc. and 
approximately $300,000 for working capital.

     Section 16(a) of the Securities Exchange Act of 1934, as amended, 
requires the Company's executive officers and directors, and persons who own 
more than 10% of a registered class of the Company's equity securities to 
file reports of ownership and changes in ownership with the Securities and 
Exchange Commission ("SEC"). Executive officers, directors and greater than 
10% stockholders are required by SEC rules to furnish the Company with copies 
of all forms they file. Based solely on its review of the copies of such 
forms received by the Company and written representations from certain 
reporting persons, the Company believes that, during fiscal 1998, all Section 
16(a) filing requirements applicable to its executive officers, directors and 
10% stockholders were satisfied, except that the Forms 4 for Leslie Johnson, 
the Senior Vice President, Client Services and Chief Service Officer, for 
September 1997 and for Mitchell Everton, the Senior Vice President, Tax and 
Operations of the Company, for April 1998 were filed late.

Statement in the sections entitled "Executive Officer Compensation" and 
"Election of Class I Director" and is incorporated herein by reference.

ITEM 12. SECURITY OWNERSHIP

     The information required is set forth in the  Company's definitive Proxy

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Between May 1994 and September 1995, Thomas H. Sinton, a Director and
officer of the Company, and his immediate family loaned an aggregate of
$1,040,000 to the Company at interest rates of 10.0% per year. The Company has
paid all such loans in full. 

     On December 5, 1996, the Company loaned $544,000 under a full recourse note
agreement at an interest rate of 6.31% per year to Robert E. Schneider, an
officer of the Company, to permit Mr. Schneider to exercise options to purchase
Common Stock of the Company. All principal and interest is due December 5, 2000.
As of June 30, 1998, Mr. Schneider had not paid any amount on the note. 

     On January 31, 1997, the Company loaned $250,000 under a full recourse note
agreement at an interest rate of 6.1% per year to Jeffrey M. Bizzack, an officer
of the Company, to permit Mr. Bizzack to purchase a residence. Accrued interest
must be paid on a monthly basis beginning two years from the date of the note.
All principal and accrued but unpaid interest is due January 31, 2001 unless
Mr. Bizzack's employment with the Company terminates, in which case, the note
may become due earlier. As of June 30, 1998, Mr. Bizzack had not paid any amount
on the note.

     Thomas H. Sinton and certain affiliates of GAP LLC are the sole
stockholders of InterPro Expense Systems, Inc., a Delaware corporation
("InterPro"), which in April 1998 purchased rights to certain early-stage travel
and entertainment expense processing software. Mr. Sinton is the President,
Chief Executive Officer and Chairman of the Board of the Company. David C.
Hodgson, a Director of the Company, is a managing member of GAP LLC, affiliates
of which hold more than 5% of the Company's outstanding stock. Because Mr.
Sinton and Mr. Hodgson are officers and Directors of the Company, their
investment in InterPro was required to be, and was, approved by the
disinterested directors of the Company. Any future transaction or relationship
between the Company and InterPro would be entered into on an arms-length basis
and would be approved by the Company's disinterested directors.
