                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements and Notes thereto
appearing elsewhere in this Prospectus. Investors should carefully consider the
risk factors related to the purchase of Class B Common Stock of the Company.
See "Risk Factors."
 
                                  THE COMPANY
 
  Tier Technologies, Inc. ("Tier" or the "Company") provides information
technology ("IT") consulting, application development and software engineering
services that facilitate the migration of clients' enterprise-wide systems and
applications to leading edge technologies. To adapt to change and remain
competitive, large corporations and government entities have sought to harness
their intellectual and informational capital by investing in advanced IT
systems. The Tier Migration Solution is a methodology developed to evaluate or
"score" the efficacy of a client's existing embedded IT capital. This approach
allows the Company to supplement and replace IT systems incrementally, preserve
viable components of the framework and integrate advanced technologies to meet
the client's specific business needs.
 
  Applying the Tier Migration Solution, the Company first assesses a client's
existing business processes and defines the scope of the project, including a
determination of the client's expectations for quantifiable business
improvement. The Company then analyzes the client's existing IT system to
determine which areas would benefit the most from the application of new
technologies. When this assessment is completed, Tier develops a specific IT
strategy that uses a system architecture consistent with the client's existing
environment. Tier then implements the recommended IT strategy. The Company
applies the Tier Migration Solution to all client projects in combination with
a formal internal risk assessment program that enables the Company to manage
and benchmark projects on an on-going basis.
   
  Through its ten offices located in the United States, the United Kingdom and
Australia, the Company works closely with its clients to determine, evaluate
and implement an IT strategy that allows the Company to rapidly adopt, deploy
and transfer emerging technologies in a cost-effective manner. Tier combines
its significant understanding of enterprise-wide IT systems with expertise in
vertical industries, such as healthcare, financial services and government
services, to provide clients with rapid and flexible migration solutions. The
Company's clients consist primarily of Fortune 1000 companies with information-
intensive businesses and government entities with large volume information and
technology needs, including Kaiser Foundation Health Plan, Inc., Equifax Europe
(UK) Ltd., the State of Missouri and the Commonwealth of Australia.     
 
  The Company seeks to become the leading provider of comprehensive IT
migration solutions to Fortune 1000 companies and large government entities.
The Company's strategy includes the following elements: (i) concentrate on
migration opportunities; (ii) develop strategic partnerships; (iii) pursue
strategic acquisitions; (iv) expand into key vertical markets; (v) expand its
geographic presence; and (vi) attract highly skilled employees. This strategy
has allowed the Company to increase revenues from $11.8 million in the nine
months ended September 30, 1996 to $22.5 million in the nine-month fiscal year
ended September 30, 1997. The Company's workforce has grown from 54 on January
1, 1995 to 231 on September 30, 1997.
   
  From December 1996 through September 1997, Tier acquired five IT service
providers for a total cost of $2.7 million, excluding future contingent
payments, to broaden its client base, acquire additional technical expertise
and supplement human resources in key vertical markets. The Company believes
these acquisitions have enabled it to gain access to international labor
markets and to compete effectively for highly skilled employees who have
particular geographic preferences.

                                 RISK FACTORS
 
  The following risk factors should be considered carefully in addition to the
other information in this Prospectus before purchasing the Class B Common
Stock offered by this Prospectus. Except for the historical information
contained herein, the discussion in this Prospectus contains certain forward-
looking statements that involve risks and uncertainties. When used in this
Prospectus, the words "believes," "expects," "anticipates," "intends,"
"estimates," "should," "will likely" and similar expressions are intended to
identify such forward-looking statements. The cautionary statements made in
this Prospectus should be read as being applicable to all related forward-
looking statements wherever they appear in this Prospectus. The Company's
actual results could differ materially from those discussed here. Important
factors that could cause or contribute to such differences include those
discussed below, as well as those discussed elsewhere herein.
 
  Variability of Quarterly Operating Results. The Company's revenues and
operating results are subject to significant variation from quarter to quarter
due to a number of factors, including the number, size and scope of projects
in which the Company is engaged; the contractual terms and degree of
completion of such projects; competitive pressures on pricing of the Company's
services; any delays incurred in connection with, or early termination of, a
project; employee utilization rates; the adequacy of provisions for losses;
the accuracy of estimates of resources required to complete ongoing projects;
demand for the Company's services generated by strategic partnerships and
certain prime contractors; the Company's ability to increase both the number
and size of engagements from existing clients; and economic conditions in the
vertical and geographic markets served by the Company. Due to the relatively
long sales cycles for the Company's services in the government services
market, the timing of revenue is difficult to forecast. In addition, the
achievement of anticipated revenues is substantially dependent on the
Company's ability to attract, on a timely basis, and retain skilled personnel.
A high percentage of the Company's operating expenses, particularly personnel
and rent, are fixed in advance. Changes in the number, scope, duration or
progress toward completion, of the Company's projects or in employee
utilization rates would cause significant variations in operating results in
any particular quarter. In addition, the Company typically reaches the annual
limitation on its FICA contributions for many of its consultants before the
end of the calendar year. As a result, payroll taxes as a component of cost of
sales will vary from quarter to quarter during the fiscal year and will
generally be higher at the beginning of the calendar year. Therefore, the
Company believes that period-to-period comparisons of its operating results
are not necessarily meaningful, should not be relied upon as indications of
future performance and may result in volatility in the price of the Class B
Common Stock. Due to the foregoing factors, among others, the Company's
operating results will from time to time be below the expectations of the
analysts and investors. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
   
  Concentration of Revenues; Dependence on Large Projects; Risk of
Termination. The Company has derived, and believes that it will continue to
derive, a significant portion of its revenues from a limited number of large
client projects. For the nine-month fiscal year ended September 30, 1997, the
State of Missouri, Kaiser Foundation Health Plan, Inc. ("Kaiser") and Unisys
Corporation ("Unisys") accounted for 22.3%, 21.1% and 19.7% of the Company's
revenues, respectively. Kaiser accounted for 59.3% and 68.1% of the Company's
revenues in 1996 and 1995, respectively, while Unisys accounted for 14.6% of
the Company's revenues in 1996. The volume of work performed for specific
clients is likely to vary from year to year, and a major client in one year
may not use the Company's services in a subsequent year. Most of the Company's
contracts are terminable by the client following limited notice and without
significant penalty to the client. The completion, cancellation or significant
reduction in the scope of a large project could have a material adverse effect
on the Company's business, financial condition and results of operations. In
addition, the amount of the Company's services required by any of its clients
can be adversely affected by a number of factors, including technological
developments and the internal budget cycles of such clients. As a result of
the Company's focus in specific vertical markets, economic and other
conditions that affect these industries could lead to a reduction in capital
spending on IT     
 
                                       6
<PAGE>
 
projects, government spending cuts or general budgetary constraints, any of
which would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and "Business -
Clients."
   
  Need to Attract and Retain Professional Staff. The Company's success will
depend in large part upon its ability to attract, retain, train, manage and
motivate skilled employees, particularly project managers and other senior
technical personnel. There is significant competition for employees with the
skills required to perform the services the Company offers. In particular,
qualified project managers and senior technical and professional staff are in
great demand worldwide and competition for such persons is likely to increase.
In addition, the Company requires that a significant number of its employees
travel to client sites to perform services on its behalf, which may make a
position with the Company less attractive to potential employees. There can be
no assurance that a sufficient number of skilled employees will continue to be
available to the Company, or that the Company will be successful in training,
retaining and motivating current or future employees. The Company's inability
to attract, retain and train skilled employees or failure of its employees to
achieve expected levels of performance could impair the Company's ability to
adequately manage and staff its existing projects and to bid for or obtain new
projects, which would have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business --
 Human Resources."     
   
  Dependence on Key Personnel. The Company's success will depend in large part
upon the continued services of a number of key employees, including its Chief
Executive Officer and Chairman of the Board of Directors, James L. Bildner,
and its President and Chief Operating Officer, William G. Barton. The loss of
the services of either of Messrs. Bildner or Barton or of one or more of the
Company's other key personnel could have a material adverse effect on the
Company's business. Although the Company has entered into employment
agreements with each of Messrs. Bildner and Barton, either of them may
terminate their employment agreement at any time. If one or more of the
Company's key employees resigns from the Company to join a competitor or to
form a competing company, the loss of such personnel and any resulting loss of
existing or potential clients to any such competitor could have a material
adverse effect on the Company's business, financial condition and results of
operations. In the event of the loss of any such personnel, there can be no
assurance that the Company would be able to prevent the unauthorized
disclosure or use of its technical knowledge, practices or procedures by such
personnel. See "Business -- Intellectual Property Rights" and "Management --
 Employment Agreements."     
   
  Control by Principal Shareholders; Voting Trust. All of the holders of Class
A Common Stock have entered into a voting trust (the "Voting Trust") with
respect to their shares of Class A Common Stock, which represents 69.6% of the
Common Stock voting power after this offering. All power to vote shares held
in the Voting Trust has been vested in the Voting Trust's trustees, Messrs.
Bildner and Barton. As a result, Messrs. Bildner and Barton will be able to
control the outcome of all corporate actions requiring shareholder approval,
including the election of a majority of the Company's directors, proxy
contests, mergers involving the Company, tender offers, open-market purchase
programs or other purchases of Common Stock that could give holders of the
Company's Class B Common Stock the opportunity to realize a premium over the
then-prevailing market price for their shares of Class B Common Stock. The
concentration of voting control could have the effect of delaying or
preventing a change in control of the Company and may affect the market price
of the Class B Common Stock. The holders of the Class A Common Stock also hold
a number of shares of Class B Common Stock that will represent 45.4% of the
shares of Class B Common Stock outstanding after this offering. If such
holders vote their shares of Class B Common Stock as a block, it is likely
they will initially be able to elect all of the directors to be elected solely
by the holders of the Class B Common Stock. In addition, as authorized by the
California Corporations Code and based upon provisions in the Company's
Amended and Restated Bylaws (the "Bylaws") and the concentration of voting
control, Messrs. Bildner and Barton may take any action which may be taken at
any meeting of shareholders, subject to certain exceptions related to the
election of     
 
                                       7
<PAGE>
 
   
directors, by written consent without formally convening a meeting of
shareholders. In addition, the Articles and Bylaws currently permit
shareholders to require cumulative voting in connection with the election of
directors, subject to certain requirements; however, the Articles and Bylaws
also provide that cumulative voting will be eliminated effective as of the
first record date for an annual meeting that the Company has equity securities
listed on Nasdaq and has 800 or more holders of its equity securities. See
"Description of Capital Stock."     
   
  Benefits of this Offering to Existing Shareholders. The existing
shareholders of the Company will benefit from the creation of a public market
for the shares of Class B Common Stock held by them after the closing of this
offering. There can be no assurance that an active public market for the Class
B Common Stock will develop after this offering or that the market price of
the Class B Common Stock will not decline below the initial public offering
price. The Selling Shareholders will receive gross proceeds of approximately
$6.8 million from the sale of 675,000 shares of Class B Common Stock offered
by them hereby at an assumed initial public offering price of $10.00 per
share, which will result in an aggregate gain of approximately $6.6 million
over the acquisition price of such shares. Following the closing of this
offering, the existing shareholders of the Company will hold a total of
5,395,953 shares of Class A and Class B Common Stock having an estimated
aggregate value equal to approximately $54.0 million at the closing of this
offering, assuming a public offering price of $10.00 per share, which will
result in an estimated aggregate unrealized gain at that time of approximately
$49.4 million over the acquisition price of such shares. See "-- No Prior
Public Market; Potential Volatility of Stock Price" and "Dilution."     
   
  Risks Associated with Rapid Technological Advances. The Company's success
will depend in part on its ability to develop IT solutions that keep pace with
continuing changes in technology, evolving industry standards and changing
client preferences. There can be no assurance that the Company will be
successful in developing such IT solutions in a timely manner or that if
developed the Company will be successful in the marketplace. Delay in
developing or failure to develop new IT solutions would have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Strategy."     
   
  Risks Associated with Possible Acquisitions. A principal component of the
Company's business strategy is to grow by acquiring additional businesses to
expand its presence in new or existing markets. From December 1996 through
September 1997, the Company acquired five businesses. There can be no
assurance that the Company will be able to identify, acquire or profitably
manage additional businesses or to integrate successfully any acquired
businesses into the Company without substantial expense, delay or other
operational or financial problems. Acquisitions may also involve a number of
special risks, including diversion of management's attention, failure to
retain key personnel, amortization of acquired intangible assets, client
dissatisfaction or performance problems with an acquired firm, assumption of
unknown liabilities, or other unanticipated events or circumstances, any of
which could have a material adverse effect on the Company's business,
financial condition and results of operations. There can be no assurance that
any acquired business will achieve anticipated revenues and operating results.
The failure of the Company to manage its acquisition strategy successfully
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Acquisitions," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business -- Strategy."     
   
  Management of Growth. The Company's growth has placed, and is expected to
continue to place, significant demands on its management, financial, staffing
and other resources. The Company has expanded geographically by opening new
offices domestically and abroad, and intends to open additional offices. The
Company's ability to manage its growth effectively will require it to continue
to develop and improve its operational, financial and other internal systems,
as well as its business development capabilities, and to train, motivate and
manage its employees. In addition, the Company's future success will depend in
large part upon its ability to continue to estimate project parameters
accurately, to maintain employee utilization rates and project quality and to
meet delivery dates, particularly if the average size and number of the
Company's projects continues to increase. If the Company is unable to manage
its     
 
                                       8
<PAGE>
 
growth and projects effectively, such inability would have a material adverse
effect on the quality of the Company's services, its ability to retain key
personnel, and its business, financial condition and results of operations.
There can be no assurance that the Company's rate of growth will continue or
that the Company will be successful in managing any such growth. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
   
  Risks Associated with Partnerships; Risk of Termination or
Nonperformance. The Company has entered into written arrangements or
understandings with certain technology and service providers pursuant to which
the providers have agreed that the Company is, or will be, the exclusive, or
one of a small number of, preferred systems integrators for that provider's
clients within specific market segments or geographic areas. These
arrangements are typically of limited duration, include broad exceptions to
each party's obligations and are terminable by either party following limited
notice and without significant penalty. Certain of these arrangements contain
provisions whereby the provider agrees to utilize a specified number of the
Company's consultants or agrees to provide the Company with business
opportunities resulting in specified revenues. There can be no assurance that
any of these arrangements will result in the future utilization of the
Company's consultants, additional business opportunities or additional
revenues. There also can be no assurance that any business opportunities that
do result from these arrangements will be on terms ultimately satisfactory or
profitable to the Company. The cancellation or a significant reduction in the
scope of any of these arrangements, or the refusal or inability of a provider
to meet its obligations under the relevant arrangement, would have a material
adverse effect on the Company's business, financial condition and results of
operations. In addition, in the government services market, the Company often
joins with another organization, such as Unisys, to obtain engagements. In
these engagements, the Company is a subcontractor to the prime contractor of
the engagement. There can be no assurance that actions or failures
attributable to the prime contractor of such engagements will not also
negatively affect the Company's business, financial condition or results of
operations. See "Business -- Strategy" and "-- Clients."     
   
  Project Risks; Liability to Clients; Client Dissatisfaction. Many of the
Company's engagements involve projects which are critical to the operations of
its clients' businesses and provide benefits that may be difficult to
quantify. The failure of the Company, or of the prime contractor on an
engagement in which the Company is a subcontractor, to meet a client's
expectations in the performance of its services could damage the Company's
reputation and adversely affect its ability to attract new business, and could
have a material adverse effect upon its business, financial condition and
results of operations. The Company has undertaken, and may in the future
undertake, projects in which the Company guarantees performance based upon
defined operating specifications or guaranteed delivery dates. Unsatisfactory
performance or unanticipated difficulties or delays in completing such
projects may result in client dissatisfaction and a reduction in payment to,
or payment of damages (as a result of litigation or otherwise) by, the
Company, which could have a material adverse effect upon its business,
financial condition and results of operations. In addition, unanticipated
delays could necessitate the use of more resources than initially budgeted by
the Company for a particular project, which also could have a material adverse
effect upon its business, financial condition and results of operations. Any
failure in a client's system could result in a claim for substantial damages
against the Company, regardless of the Company's responsibility for such
failure. There can be no assurance that the limitations of liability set forth
in the Company's service contracts will be enforceable or will otherwise
protect the Company from liability for damages. Although the Company maintains
general liability insurance coverage, including coverage for errors or
omissions, there can be no assurance that such coverage will continue to be
available on reasonable terms, will be available in sufficient amounts to
cover one or more claims or that the insurer will not disclaim coverage as to
any future claim. The successful assertion of one or more claims against the
Company that exceed available insurance coverage or changes in the Company's
insurance policies, including premium increases or the imposition of large
deductible or co-insurance requirements, would adversely affect the Company's
business, financial condition and results of operations. See "Business --
 Representative Engagements" and "-- Clients."     
 
                                       9
<PAGE>
 
   
  Reliance on Government Contracts; Risk of Termination. For the nine-month
fiscal year ended September 30, 1997, 45.1% of the Company's revenues were
derived from sales to government agencies. A significant reduction in
government funds available for agencies or departments to which Tier supplies
IT services, either due to budget cuts or the imposition of budgetary
constraints, or a determination by the particular federal, state or foreign
government that funding of such agencies or departments should be reduced or
discontinued, would have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, the loss of a
major government client, or any significant reduction or delay in orders by
such client, would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Sales and
Marketing" and "-- Clients."     
   
  Fixed Price Contracts; Budget Overruns. During fiscal 1996 and the nine-
month fiscal year ended September 30, 1997, 1.4% and 12.4%, respectively, of
the Company's revenues were generated on a fixed price basis, rather than on a
time and materials basis. The Company's failure to estimate accurately the
resources required for a fixed price project or its failure to complete its
contractual obligations in a timely manner consistent with the project plan
upon which its fixed price contract is based could have a material adverse
effect on the Company's business, financial condition and results of
operations. In addition, the Company may establish prices before project
design specifications are finalized, which could result in a fixed price that
proves to be too low and therefore adversely affects the Company's business,
financial condition and results of operations. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."     
   
  Substantial Competition. The IT services market is highly competitive and is
served by numerous international, national and local firms. Market
participants include systems consulting and integration firms, including
national accounting firms and related entities, the internal information
systems groups of its prospective clients, professional services companies,
hardware and application software vendors, and divisions of large integrated
technology companies and outsourcing companies. Many of these competitors have
significantly greater financial, technical and marketing resources, generate
greater revenues and have greater name recognition than the Company. In
addition, there are relatively low barriers to entry into the IT services
market, and the Company has faced, and expects to continue to face, additional
competition from new entrants into the IT services market.     
   
  The Company believes that the principal competitive factors in the IT
services market include reputation, project management expertise, industry
expertise, speed of development and implementation, technical expertise,
competitive pricing, and the ability to deliver results on a fixed price as
well as a time and materials basis. The Company believes that its ability to
compete also depends in part on a number of competitive factors outside its
control, including the ability of its clients or competitors to hire, retain
and motivate project managers and other senior technical staff; the ownership
by competitors of software used by potential clients; the price at which
others offer comparable services; the ability of its clients to perform the
services themselves; and the extent of its competitors' responsiveness to
client needs. There can be no assurance that the Company will be able to
compete effectively on pricing or other requirements with current and future
competitors or that competitive pressures will not cause the Company's
revenues or income to decline or otherwise materially adversely affect its
business, financial condition and results of operations. See "Business --
 Competition."     
   
  Intellectual Property Rights; Limited Protection; Inability to Resell or
Reuse Rights. The Company relies on a combination of trade secrets,
nondisclosure and other contractual arrangements, and copyright and trademark
laws to protect its intellectual property rights. The Company enters into
confidentiality agreements with its employees, generally requires that its
consultants and clients enter into such agreements and limits access to its
proprietary information. There can be no assurance that the steps taken by the
Company in this regard will be adequate to avoid the loss or misappropriation
of its proprietary information, or that the Company will able to detect
unauthorized use of such information and take appropriate steps to enforce its
intellectual property rights.     
 
  A portion of the Company's business involves the development of software
applications for specific client engagements. Ownership of such software is
the subject of negotiation with each particular client
 
                                      10
<PAGE>
 
and is typically assigned to the client. The Company also develops software
application frameworks, and may retain ownership or marketing rights to these
application frameworks, which may be adapted through further customization for
future client projects. Certain clients have prohibited the Company from
marketing the software and application frameworks developed for them entirely
or for specified periods of time or to specified third parties, and there can
be no assurance that clients will not demand similar or other restrictions in
the future. Issues relating to the ownership of and rights to use software and
application frameworks can be complicated, and there can be no assurance that
disputes will not arise that affect the Company's ability to resell or reuse
such software and application frameworks.
   
  Although the Company believes that its services and products do not infringe
on the intellectual property rights of others, there can be no assurance that
such a claim will not be asserted against the Company in the future, or that
if asserted, any such claim will be successfully defended. See "Business --
Intellectual Property Rights."     
   
  Risks of Conducting International Operations. International operations in
Australia and the United Kingdom accounted for 13.7% of the Company's total
revenues for the nine-month fiscal year ended September 30, 1997. In addition,
a significant portion of the Company's sales are to large multinational
companies. To meet the needs of such companies, both domestically and
internationally, the Company must provide worldwide services, either directly
or indirectly. As a result, the Company intends to expand its existing
international operations and enter additional international markets, which
will require significant management attention and financial resources and
could adversely affect the Company's operating margins and earnings. In order
to expand international operations, the Company will need to hire additional
personnel and develop relationships with potential international clients
through acquisition or otherwise. To the extent that the Company is unable to
do so on a timely basis, any growth of the Company in international markets
would be limited, and the Company's business, financial condition and results
of operations would be materially and adversely affected.     
 
  The Company's international business operations are subject to a number of
risks, including, but not limited to, difficulties in building and managing
foreign operations, enforcing agreements and collecting receivables through
foreign legal systems, longer payment cycles, fluctuations in the value of
foreign currencies and unexpected regulatory, economic or political changes in
foreign markets. The Company does not currently engage in hedging
transactions. There can be no assurance that these factors will not have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
   
  Shares Eligible for Future Sale. Sales of substantial amounts of Class B
Common Stock in the public market following this offering could have a
material adverse effect on the market price of the Class B Common Stock. The
3,400,000 shares of Class B Common Stock offered hereby will be freely
tradable without restriction under the Securities Act of 1993, as amended (the
"Securities Act"). Each of the Selling Shareholders, who will, upon the
closing of the offering, hold an aggregate of 779,762 shares of Class A Common
Stock and 2,288,572 shares of Class B Common Stock, and options to purchase a
total of 410,000 shares of Class B Common Stock, has agreed that they will not
offer, sell, contract to sell or otherwise dispose of any shares of Common
Stock owned beneficially by them for 365 days after the date of this
Prospectus, subject to certain exceptions. Each executive officer, director,
current shareholder or optionee, other than the Selling Shareholders, who
will, upon the closing of this offering, hold an aggregate of 860,000 shares
of Class A Common Stock and 1,467,619 shares of Class B Common Stock and
options to purchase a total of 20,000 shares of Class A Common Stock and a
total of 1,303,075 shares of Class B Common Stock, has agreed that they will
not offer, sell, contract to sell or otherwise dispose of any shares of Common
Stock owned beneficially by them for a period of 180 days after the date of
this Prospectus, subject to certain exceptions. To the extent that a
significant portion of such shares are sold by the holders thereof, such sales
may adversely affect the market price of the Class B Common Stock. Pursuant to
an agreement between the Company and the holders of 420,953 shares of Class B
Common Stock, such holders are entitled to certain demand and piggyback
registration rights with respect to such     
 
                                      11
<PAGE>
 
   
shares. If such holders, by exercising their demand registration rights, cause
a large number of shares to be registered and sold in the public market, such
sales could have an adverse effect on the market price for the Class B Common
Stock. If the Company were required to include in a Company-initiated
registration shares held by such holders pursuant to the exercise of their
piggyback registration rights, such sales may have an adverse effect on the
Company's ability to raise needed capital. After completion of this offering,
the Company intends to file a Form S-8 registration statement under the
Securities Act to register all shares of Class B Common Stock issuable under
the Company's Amended and Restated 1996 Equity Incentive Plan and the Employee
Stock Purchase Plan. See "Description of Capital Stock -- Registration Rights"
and "Shares Eligible for Future Sale."     
 
  Unspecified Use of Proceeds. The principal purposes of this offering are to
increase the Company's working capital and financial flexibility, to repay
certain indebtedness, to facilitate future access by the Company to public
equity markets and to provide increased visibility, credibility and name
recognition for the Company in a marketplace where many of its competitors are
publicly held companies. The Company has not yet identified specific uses for
a majority of the net proceeds, and, pending such uses, the Company expects
that it will invest such net proceeds in short-term, interest-bearing
investment-grade securities. Accordingly, the Company's management will have
broad discretion as to the use of such net proceeds without any action or
approval of the Company's shareholders. See "Use of Proceeds."
 
  No Prior Public Market; Potential Volatility of Stock Price. Prior to this
offering there has been no public market for the Class B Common Stock. There
can be no assurance that an active public market for the Class B Common Stock
will develop after this offering or that the market price of the Class B
Common Stock will not decline below the initial public offering price.
 
  The market for securities of early stage companies has been highly volatile
in recent years as a result of factors often unrelated to a company's
operations. Factors such as quarterly variations in operating results,
announcements of technological innovations or new products or services by the
Company or its competitors, general conditions in the IT industry or the
industries in which Tier's clients compete, changes in earnings estimates by
securities analysts and general economic conditions such as recessions or high
interest rates could contribute to the volatility of the price of the Class B
Common Stock and could cause significant fluctuations. Further, in the past,
following periods of volatility in the market price of a company's securities,
securities class action litigation has often been instituted against the
issuing company. Such litigation could result in substantial costs and a
diversion of management's attention and resources, which could have a material
adverse effect on the Company's business, financial condition and results of
operations. Any adverse determination in such litigation could also subject
the Company to significant liabilities. There can be no assurance that such
litigation will not be instituted in the future with respect to the Company.
   
  Issuance of Preferred Stock; Potential Adverse Effects to Holders of Common
Stock. The Board of Directors has the authority to issue Preferred Stock and
to determine the preferences, limitations and relative rights of shares of
Preferred Stock and to fix the number of shares constituting any series and
the designation of such series, without any further vote or action by the
Company's shareholders. The Preferred Stock could be issued with voting,
liquidation, dividend and other rights superior to the rights of the Class B
Common Stock. The potential issuance of Preferred Stock may delay or prevent a
change in control of the Company, discourage bids for the Class B Common Stock
at a premium over the market price and adversely affect the market price and
the voting and other rights of the holders of the Common Stock. See
"Description of Capital Stock -- Preferred Stock."     
   
  Immediate and Substantial Dilution. Based on an assumed initial public
offering price of $10.00 per share, investors who purchase shares of Class B
Common Stock in this offering will incur immediate dilution in pro forma net
tangible book value of $6.95 per share. See "Dilution."     
 
  No Dividends. The Company has never declared or paid cash dividends on its
capital stock and does not anticipate paying any cash dividends in the
foreseeable future. See "Dividend Policy."

                                  THE COMPANY
 
  Tier was incorporated in the State of California in 1991. The Company
maintains its principal executive offices at 1350 Treat Boulevard, Suite 250,
Walnut Creek, California 94596. The Company's telephone number is (510) 937-

                                 ACQUISITIONS
   
  From December 1996 through September 1997, the Company made five strategic
acquisitions for a total cost of $2.7 million, excluding future contingent
payments, all of which were structured and accounted for as asset purchases.
Acquisition prices were determined based on arm's length negotiations with
unaffiliated third parties. Factors considered by the Company in making such
determinations included geographic opportunities, consulting resources and
strategic client relationships offered through the acquisition.     
 
  On December 16, 1996, the Company acquired certain assets and liabilities of
Chicago Consulting Alliance, LLC ("CCA"). CCA was based in Chicago, Illinois
and provided consulting services for the custom design of software and
computer systems for business applications. The CCA acquisition allowed the
Company to expand its geographic and client base into the Chicago market. The
cost of the acquisition was $170,000.
 
  On December 31, 1996, the Company acquired certain assets and liabilities of
Encore Consulting, Inc. ("Encore"), a Missouri-based corporation, which
provided consulting services for computer systems integration under a
government contract. The Encore acquisition added to Tier's established state
government IT practice. The cost of the acquisition totalled $934,000. A
$150,000 contingent payment is payable by the Company upon the second year's
renewal of this contract.
 
  On January 2, 1997, the Company acquired certain assets and liabilities of
Five Points Consulting, LLC, ("Five Points") which was based in Atlanta,
Georgia. Five Points provided custom designed software and computer systems
for special business applications. Tier acquired Five Points for its
technological expertise with Java, as well as to expand into the southeastern
United States. The cost of the acquisition totalled $284,000.
   
  On March 10, 1997 the Company acquired certain assets and liabilities of
Tangent Group, Pty, Limited, ("Tangent Group") an Australian entity which
provided computer systems consulting services. The Tangent Group acquisition
provided Tier with a local base to support its Australian IT practice and a
foundation for Tier's resource and recruiting needs for a project being
conducted for the Australian federal government. The cost of the acquisition
totalled $488,000. In addition, the Company will pay at least $120,000 in
royalties over the first two-year period following the acquisition. The
royalty is based on 3.0% of the Company's gross revenues generated by its
Australian operations. The maximum amount of royalties to be paid over the
first three-year period following the acquisition is approximately $240,000.
    
  On July 11, 1997, the Company acquired certain assets and liabilities of
Albanycrest Limited, ("Albanycrest"), a United Kingdom private limited
company, which provided information and management consulting services on the
design of software and computer systems. The Albanycrest acquisition added to
Tier's financial services expertise and provided a platform for the expansion
of Tier's international practice into the United Kingdom and Europe. The
purchase price totalled $868,000. Contingent payments of up to $407,000 will
be paid if certain performance criteria are met.
 
  While the Company in the ordinary course of business regularly evaluates and
enters into negotiations relating to potential acquisition opportunities, as
of the date of this Prospectus, there are no existing commitments or
agreements with respect to any future acquisitions.

                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 2,725,000 shares of
Class B Common Stock offered by the Company hereby at an assumed initial
public offering price of $10.00 per share, after deducting the estimated
underwriting discounts and estimated offering expenses payable by the Company,
are estimated to be approximately $24.2 million. The Company will not receive
any proceeds from the sale of shares by the Selling Shareholders. See
"Principal and Selling Shareholders."     
   
  The Company intends to use a portion of the net proceeds from this offering
to repay all borrowings under its credit facility, which totaled $3.5 million
at November 10, 1997 (borrowings totaled $2.8 million at September 30, 1997).
The revolving and term components of the current credit facility bear interest
at the bank's prime rate plus 1.50% and 1.75% per annum, respectively, and
mature in December 1998. Following such repayment, the Company will maintain
the credit facility through its term to fund future financing requirements.
The Company has used the proceeds from borrowings to fund working capital
requirements, the growth of the business and selective acquisitions. For a
description of the terms of the credit facility, see "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources." The Company intends to use the remaining net proceeds from
this offering for working capital and other general corporate purposes, which
may include the acquisition of capital equipment and leasehold improvements
totaling approximately $800,000. In the normal course of business, the Company
evaluates potential acquisitions of businesses that would complement or expand
the Company's business. A portion of the net proceeds may be used for one or
more such acquisitions, although the Company has no present commitments or
agreements with respect to any such acquisitions and no portion of the net
proceeds has been allocated for any specific acquisition. Pending such uses,
the Company intends to invest the remaining net proceeds of this offering in
investment-grade securities, including short-term, interest-bearing money
market funds.     
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid cash dividends on its Common Stock.
The Company's credit facility contains restrictions on the Company's ability
to pay cash dividends. The Company currently intends to retain future
earnings, if any, to fund the development and growth of its business and does
not anticipate paying any cash dividends in the foreseeable future.

                                   DILUTION
 
  The pro forma net tangible book value of the Common Stock as of September
30, 1997 was approximately $2.5 million or $0.41 per share. Pro forma net
tangible book value per share represents the Company's total tangible assets
less total liabilities, divided by the total number of shares of Common Stock
outstanding assuming the conversion of the outstanding shares of Series A
Preferred Stock into shares of Class B Common Stock.
   
  After giving effect to the sale of the 2,725,000 shares of Class B Common
Stock by the Company offered hereby and the receipt of the net proceeds
therefrom, the pro forma net tangible book value of the Company as of
September 30, 1997 would have been approximately $26.8 million or $3.05 per
share. This represents an immediate increase in pro forma net tangible book
value of $2.64 per share to existing shareholders and an immediate dilution in
pro forma net tangible book value of $6.95 per share to purchasers of Class B
Common Stock in this offering. The following table illustrates the per share
dilution as of September 30, 1997:

(1) Includes 30,000 shares to be issued upon the exercise of options by
    certain Selling Shareholders prior to this offering at an exercise price
    of $3.25 per share.
 
  At September 30, 1997, there were outstanding options to purchase 20,000
shares of Class A Common Stock at an exercise price of $3.58 per share and
1,713,075 shares of Class B Common Stock at a weighted average exercise price
of $3.94 per share. To the extent such options are exercised, there will be
dilution to new shareholders.
 
  The sale of Class B Common Stock by the Selling Shareholders in this
offering will reduce the pro forma number of shares held by existing
shareholders as of September 30, 1997 to 5,395,953, or approximately 61.3% of
the total number of shares of Common Stock outstanding immediately after this
offering (58.0% if the underwriters over-allotment option is exercised in
full), and will increase the number of shares to be purchased by new
shareholders to 3,400,000, or approximately 38.7% of the total number of
shares of Common Stock outstanding immediately after this offering (42.0% if
the underwriters over-allotment option is exercised in full). See "Principal

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
   
  Tier provides IT consulting, application development and software
engineering services that facilitate the migration of clients' enterprise-wide
systems and applications to leading edge technologies. Through its ten offices
located in three countries, the Company works closely with its Fortune 1000,
government and other clients to determine, evaluate and implement an IT
strategy that allows it to rapidly adopt, deploy and transfer emerging
technologies while preserving viable elements of the client's installed IT
base. From its founding in 1991 through 1994, the Company provided third party
IT services through a workforce consisting primarily of independent
contractors hired to staff particular engagements. In 1995, the Company began
employing more full-time, salaried IT consultants. As of September 30, 1997,
75.6% of the Company's IT consultants were salaried employees, with the
remaining consultants being hourly contractors. The composition of its
workforce provides the Company with staffing flexibility. Revenues increased
from $11.8 million in the nine months ended September 30, 1996 to $22.5
million in the nine-month fiscal year ended September 30, 1997. The Company's
workforce has grown from 54 on January 1, 1995 to 231 on September 30, 1997.
       
  The Company's revenues are derived primarily from professional fees billed
to clients on either a time and materials or a fixed price basis. Time and
materials revenues are recognized as services are performed. Fixed price
revenues are recognized using the percentage-of-completion method, based upon
the ratio of costs incurred to total estimated project costs. During fiscal
1996 and the nine-month fiscal year ended September 30, 1997, 1.4% and 12.4%,
respectively, of the Company's revenues were generated on a fixed price basis.
The Company's risk management committee monitors all material projects,
focusing primarily on factors such as size of revenue and credit exposure to
the Company, number of resources employed, progress against defined project
milestones, clarity of user expectations and definition of project scope.
Substantially all of Tier's contracts are terminable by the client following
limited notice and without significant penalty to the client. To date, the
Company has generally been able to obtain an adjustment in its fees following
a significant change in the assumptions upon which the original estimate was
made, but there can be no assurance that the Company will be successful in
obtaining adjustments in the future.     
 
  The Company has derived, and believes that it will continue to derive, a
significant portion of its revenue from a small number of large clients. For
many of these clients, the Company performs a number of different projects
pursuant to multiple contracts or purchase orders. For fiscal 1997, the State
of Missouri, Kaiser and Unisys accounted for 22.3%, 21.1% and 19.7% of the
Company's revenues, respectively.
 
  Personnel and rent expenses represent a significant percentage of the
Company's operating expenses and are relatively fixed in advance of any
particular quarter. Senior management manages the Company's personnel
utilization rates by carefully monitoring its needs and basing most personnel
increases on specific project requirements. To the extent revenues do not
increase at a rate commensurate with these additional expenses, the Company's
results of operations could be materially and adversely affected.
 
  From December 1996 through September 1997, the Company made five
acquisitions for a total cost of $2.7 million, excluding future contingent
payments, all of which were structured and accounted for as asset purchases.
These acquisitions helped to expand the Company's operations in the United
States, to establish the Company's operations in Australia and the United
Kingdom, to broaden the Company's client base and technical expertise and to
supplement its access to human resources. International operations accounted
for 13.7% of fiscal 1997 revenues. International operations may subject the
Company to foreign currency translation adjustments and transaction gains and
losses for amounts denominated in foreign currencies. The Company does not
currently engage in hedging transactions.
 
  In September 1997, the Company changed its fiscal year end to September 30.
Fiscal year 1997 is comprised of the nine months ended September 30, 1997.

</TABLE>
 
NINE-MONTH FISCAL YEAR ENDED SEPTEMBER 30, 1997 AND THE NINE MONTHS ENDED
SEPTEMBER 30, 1996
   
  Revenues. Revenues increased 90.7% to $22.5 million for the nine-month
fiscal year ended September 30, 1997 from $11.8 million in the nine months
ended September 30, 1996. This increase resulted primarily from revenues
associated with the five acquisitions completed since December 1996, internal
growth, including $2.1 million from a significant new contract, and an
increase in billing rates for the Company's IT consultants.     
   
  Gross Profit. Cost of revenues consists of those costs directly attributable
to providing service to a client, including consultant salaries, benefits and
travel expenses. Gross profit increased 142.3% to $7.6 million for the nine-
month fiscal year ended September 30, 1997 from $3.1 million in the nine
months ended September 30, 1996. Gross margin increased to 33.6% for the nine-
month fiscal year ended September 30, 1997 from 26.5% in the nine months ended
September 30, 1996. The improvement in gross margin was primarily attributable
to an increased use of salaried employees as opposed to hourly employees,
higher billing rates, larger contracts and an increased use of fixed price
contracts.     
 
  Selling and Marketing. Selling and marketing expenses consist primarily of
personnel costs, sales commissions, product literature and participation in
conferences and trade shows. Selling and marketing expenses increased 218.2%
to $1.8 million for the nine-month fiscal year ended September 30, 1997 from
$577,000 in the nine months ended September 30, 1996. As a percentage of
revenues, selling and marketing expenses increased to 8.1% for the nine-month
fiscal year ended September 30, 1997 from 4.9% in the nine months ended
September 30, 1996. This increase was primarily attributable to the addition
of sales and marketing personnel and the Company's increased participation in
conferences and trade shows.
   
  General and Administrative. General and administrative expenses consist
primarily of personnel costs related to general management functions, human
resources, recruiting, finance, accounting and information systems, as well as
professional fees related to legal, audit, tax and recruiting matters. General
and administrative expenses increased 147.9% to $4.4 million for the nine-
month fiscal year ended September 30, 1997 from $1.8 million in the nine
months ended September 30, 1996. As a percentage of revenues, general and
administrative expenses increased to 19.6% for the nine-month fiscal year
ended September 30, 1997 from 15.0% in the nine months ended September 30,
1996. This increase was primarily attributable to building the infrastructure
to support, manage and control the Company's growth. The Company believes that
general and administrative expenses will continue to increase as the Company
grows     
 
                                      19
<PAGE>
 
   
but that such expenses will decrease as a percentage of revenues as the
Company realizes economies of scale from its administrative infrastructure.
       
  Depreciation and Amortization. Depreciation and amortization consists
primarily of costs associated with the straight line method depreciation of
equipment and improvements and amortization of certain other intangible assets
resulting from acquisitions. Depreciation and amortization increased 389.3% to
$274,000 for the nine-month fiscal year ended September 30, 1997 from $56,000
in the nine months ended September 30, 1996. As a percentage of revenues,
depreciation and amortization increased to 1.2% for the nine-month fiscal year
ended September 30, 1997 from 0.5% in the nine months ended September 30,
1996. The increase in depreciation and amortization expense was primarily due
to the depreciation associated with increased capital expenditures and the
amortization of increased intangible assets.     
   
  Interest Income and Interest Expense, Net. Interest income and interest
expense, net increased 98.0% to a net expense of $99,000 for the nine-month
fiscal year ended September 30, 1997 from a net expense of $50,000 in the nine
months ended September 30, 1996. This increase was primarily attributable to
the increase in borrowings under the Company's bank lines of credit to fund
working capital, capital expenditures and acquisitions.     
 
  Provision for Income Taxes. Provision for income taxes increased 44.4% to
$384,000 for the nine-month fiscal year ended September 30, 1997 from $266,000
in the nine months ended September 30, 1996. The effective tax rate for fiscal
1997 was 40.2%, compared to 40.0% for the nine months ended September 30,
1996.
 
FISCAL YEARS ENDED DECEMBER 31, 1996 AND DECEMBER 31, 1995
 
  Revenues. Revenues increased 30.9% to $16.2 million for fiscal 1996 from
$12.4 million in fiscal 1995. This increase was primarily attributable to an
increase in billing rates, an increase in revenue from government service
contracts and the overall growth of the business.
 
  Gross Profit. Gross profit increased 38.5% to $4.6 million for fiscal 1996
from $3.3 million in fiscal 1995. Gross margin increased to 28.3% for fiscal
1996 from 26.7% in fiscal 1995. This increase was primarily attributable to an
increased use of salaried employees rather than hourly employees, higher
billing rates, larger contracts and an increased use of fixed price contracts.
 
  Selling and Marketing. Selling and marketing expenses increased 55.5% to
$975,000 for fiscal 1996 from $627,000 in fiscal 1995. As a percentage of
revenues, selling and marketing expenses increased to 6.0% for fiscal 1996
from 5.0% in fiscal 1995. This increase was primarily attributable to the
hiring of additional sales and marketing employees during the period.
 
  General and Administrative. General and administrative expenses increased
65.0% to $2.6 million for fiscal 1996 from $1.6 million in fiscal 1995. As a
percentage of revenues, general and administrative expenses increased to 15.9%
for fiscal 1996 from 12.6% in fiscal 1995. This increase was primarily
attributable to building the infrastructure to support, manage and control the
Company's growth.
 
  Depreciation and Amortization. Depreciation and amortization increased 77.8%
to $80,000 for fiscal 1996 from $45,000 in fiscal 1995. This increase was
primarily due to increased capital expenditures and the associated
depreciation.
   
  Interest Income and Interest Expense, Net. Interest income and interest
expense, net increased 21.3% to a net expense of $74,000 for fiscal 1996 from
a net expense of $61,000 in fiscal 1995. This increase was primarily
attributable to an increase in borrowings.     
 
  Provision for Income Taxes. Provision for income taxes decreased 38.4% to
$351,000 for fiscal 1996 from $570,000 in fiscal 1995. The effective tax rate
for fiscal 1996 was 40.0% from 56.2% for fiscal 1995. The decrease in the
effective tax rate was primarily attributable to a one-time tax expense of
$165,000 taken in 1995 related to the Company's recording of deferred income
taxes upon dissolution of Tier Group, a partnership, and the transfer of
assets to the Company. Excluding this one-time tax expense, the effective tax
rate for fiscal 1995 would have been 40.0%.

  The Company's revenues and operating results are subject to significant
variation from quarter to quarter due to many factors, including the number,
size and scope of projects in which the Company is engaged; the contractual
terms and degree of completion of such projects; competitive pressures on the
pricing of the Company's services; any delays incurred in connection with, or
early termination of, a project; employee utilization rates; the adequacy of
provisions for losses; the accuracy of estimates of resources required to
complete ongoing projects; demand for the Company's services generated by
strategic partnerships and certain prime contractors; the Company's ability to
increase both the number and size of engagements from existing clients; and
economic conditions in the vertical and geographic markets served by the
Company. Due to the relatively long sales cycles for the Company's services in
the government services market, the timing of revenue is difficult to
forecast. In addition, the achievement of anticipated revenues is
substantially dependent on the Company's ability to attract, on a timely
basis, and retain skilled personnel.
 
  A high percentage of the Company's operating expenses, particularly
personnel and rent, are fixed in advance. Changes in the number, scope,
duration or progress toward completion, of the Company's projects or in
employee utilization rates would cause significant variations in operating
results in any particular quarter. In addition, the Company typically reaches
the annual limitation on its FICA contributions for many of its consultants
before the end of the calendar year. As a result, payroll taxes as a component
of cost of revenues will vary from quarter to quarter during the fiscal year
and will generally be higher at the beginning of the calendar year. As a
result, the Company believes that period-to-period comparisons of its
operating results are not necessarily meaningful, should not be relied upon as
indications of future performance and may result in volatility in the price of
the Company's Class B Common Stock in the public market. Due to the foregoing
factors, among others, the Company's operating results will from time to time
be below the expectations of the public market analysts and investors.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  To date, the Company has financed its operations principally through cash
flows from operating activities, the private placement of equity securities
and proceeds from borrowings under asset-based lines of credit.
   
  The Company's principal capital requirement is to fund working capital to
support its growth. The Company utilizes asset-based loan facilities to fund
working capital requirements. In November 1997, the Company entered into a
$5.0 million credit facility (the "New Credit Facility") that matures in
December 1998. The revolving portion of this facility allows the Company to
borrow the lesser of the sum of 80% of eligible accounts receivable or $4.5
million. The New Credit Facility also allows for up to $500,000 of borrowings
for equipment through a term facility. The New Credit Facility is secured by
all of the Company's assets and contains certain restrictive covenants,
including limitations on amounts of loans the Company may extend to officers
and employees and the incurrence of additional debt. Certain executive
officers have personally guarantied the New Credit Facility. The guarantees
terminate upon completion of this offering if the Company obtains certain debt
to tangible net worth ratios, which it expects to do. The New Credit Facility
requires the maintenance of certain financial ratios, including minimum
tangible net worth and a limit on the ratio of total liabilities to total
tangible net worth.     
   
  As of November 10, 1997, the principal amount outstanding under the New
Credit Facility, excluding outstanding checks and deposits that have been
included in the New Credit Facility balance in the Company's Consolidated
Financial Statements, was approximately $3.5 million and approximately
$600,000 remained available for borrowing. The revolving and term components
of the New Credit Facility bear interest at the bank's prime rate plus 1.50%
and 1.75% per annum, respectively. The Company intends to repay all of the
borrowings under the New Credit Facility with a portion of the proceeds from
this offering. Following such repayment, the Company will maintain the New
Credit Facility through its maturity in December 1998 to fund future financing
requirements.     
 
 
                                      22
<PAGE>
 
   
  As of September 30, 1997, prior to obtaining the New Credit Facility, the
Company had a $4.3 million credit facility (the "Old Credit Facility"). The
revolving portion of this facility allowed the Company to borrow the lesser of
the sum of 85% of eligible receivables (approximately $3.1 million as of
September 30, 1997) or $3.75 million. This facility allowed for the financing
of acquisitions up to $1.5 million. The Old Credit Facility also allowed for
up to $500,000 of borrowings for equipment and software. The Old Credit
Facility was secured by all of the Company's assets and contained certain
restrictive covenants, including limitations on amounts of loans the Company
may extend to officers and employees, the incurrence of additional debt and
the payment of dividends on the Company's common or preferred stock. Certain
executive officers had personally guarantied the Old Credit Facility. The
agreement required the maintenance of certain financial ratios, including
minimum tangible net worth and a limit on the ratio of total liabilities to
total tangible net worth. At September 30, 1997, the Company was not in
compliance with the covenant limiting annual capital expenditures and had
received a letter from the bank waiving such noncompliance.     
   
  As of September 30, 1997, the principal amount outstanding under the Old
Credit Facility was $2.8 million, and approximately $900,000 remained
available for borrowing. The revolving and acquisition line components of the
Old Credit Facility, bore interest at the bank's prime rate plus 1.50% and
1.75%, per annum respectively. All borrowings under the Old Credit Facility
were repaid in November 1997 through borrowings under the New Credit Facility
and the Old Credit Facility is no longer in effect.     
   
  The Company currently plans to make additional investments in equipment and
leasehold improvements of approximately $800,000 in fiscal 1998, principally
for leasehold improvements, furniture, software, personal computers and other
technology equipment, which the Company intends to fund through working
capital, borrowings under its New Credit Facility or proceeds from this
offering.     
   
  Net cash (used in) provided by operating activities was $(177,000) in fiscal
1995, $491,000 in fiscal 1996 and $(1.7) million in the nine-month fiscal year
ended September 30, 1997. Throughout these periods, the Company experienced
increases in receivables as a result of increases in the Company's sales
volume, which were partially offset by increases in accounts payable and
accrued expenses in those periods.     
 
  Net cash used in investing activities totaled $116,000, $297,000, and $2.9
million for fiscal 1995, fiscal 1996 and the nine-month fiscal year ended
September 30, 1997, respectively. These activities consisted primarily of
purchases of equipment and leasehold improvements in fiscal 1995 and fiscal
1996. In the nine-month fiscal year ended September 30, 1997, the Company made
several acquisitions in addition to the purchase of property and equipment.
   
  Net cash provided from financing activity totaled $271,000, $112,000, and
$4.4 million for fiscal 1995, fiscal 1996 and the nine-month fiscal year ended
September 30, 1997, respectively. In the nine-month fiscal year ended
September 30, 1997, the Company raised gross proceeds of $2.2 million through
the issuance of 420,953 shares of Series A Preferred Stock and increased its
borrowing by $2.1 million under its Old Credit Facility.     
 
  The Company anticipates that its existing capital resources, including cash
provided by operating activities and available bank borrowings, together with
the anticipated net proceeds from this offering, will be adequate to fund the
Company's operations for at least the next 12 months. There can be no
assurance that changes will not occur that would consume available capital
resources before such time. The Company's capital requirements depend on
numerous factors, including potential acquisitions, the timing of the receipt
of accounts receivable and employee growth. To the extent that the Company's
existing capital resources, together with the anticipated net proceeds of this
offering, are insufficient to meet its capital requirements, the Company will
have to raise additional funds. There can be no assurance that additional
funding, if necessary, will be available on favorable terms, if at all.

                                   BUSINESS
   
  Tier Technologies, Inc. ("Tier" or the "Company") provides information
technology ("IT") consulting, application development and software engineering
services that facilitate the migration of clients' enterprise-wide systems and
applications to leading edge technologies. Tier provides IT migration
solutions by applying the Tier Migration Solution, a methodology by which the
Company evaluates or "scores" the efficacy of a client's existing imbedded IT
capital against its business goals. Through its ten offices located in three
countries, the Company works closely with its Fortune 1000, government and
other clients to determine, evaluate and implement an IT strategy that allows
it to rapidly adopt, deploy and transfer emerging technologies while
preserving viable elements of the client's installed IT base. Tier combines
significant understanding of enterprise-wide IT systems with expertise in
vertical industries such as healthcare, financial services and government
services to provide clients with rapid and flexible migration solutions. By
helping clients maintain their core IT systems, Tier provides high value,
cost- effective, flexible solutions that minimize the risks associated with
migration to new technologies.     
 
BACKGROUND
 
  Today, large corporations and government agencies often face a number of
challenges, including a rapidly changing operating environment, intense
competitive pressures and accelerating technological change. To adapt to
change and remain competitive, these organizations have sought to harness
their intellectual and informational capital by investing in advanced IT
systems. As these organizations have become increasingly dependent on more
complex IT systems, their ability to integrate advanced technologies in a
rapid, reliable and cost-effective manner has become critical to their
success.
 
  The migration of enterprise-wide IT systems, which is the process of
incrementally supplementing and replacing IT system components to integrate
advanced technologies, has become a key competitive strategy. This process
enables an organization to preserve the imbedded capital in its installed base
of IT systems, to obtain the benefits of technological innovations and to
mitigate some of the risks, costs and delays inherent in full system
replacements. Several forces are driving the increased use of rapid migration
strategies. As a result of the increasing pace of technological change along
with rapid changes in competitive and business environments, the useful lives
of new technologies have tended to shorten dramatically. To capture more of
the benefits of these technologies, IT projects must be designed and completed
relatively quickly or they risk being out of date upon completion.
Organizations are re-using existing IT components both to preserve the
significant imbedded capital represented by those systems and to achieve new
functionality. For example, mainframe computers are now being used as high
volume servers in distributed computing environments because of their data
storage capacity and transaction processing speeds. As the length and scope of
an IT project expands, so too does the likelihood that the project will fail
to satisfy time, cost or functionality expectations. Consequently,
organizations seek high-impact IT solutions that can be implemented quickly.
   
  Given the complex and mission-critical nature of IT systems, many
organizations choose to outsource the development and eventual migration of
these systems to new technologies. According to Dataquest Incorporated, the
worldwide market for IT professional services was estimated to be $133 billion
in 1997, with a projected annual growth rate of over 16% through the year
1999. The Company believes that successful IT service providers will be
characterized by (i) significant experience in the migration of enterprise-
wide IT systems; (ii) an ability to adopt, deploy and transfer relevant,
emerging technologies rapidly and reliably; (iii) an understanding of the
client's industry, business and existing IT environments; (iv) successful
management of the risks inherent in large system projects; and (v) the ability
to deliver services on a global basis.

THE TIER MIGRATION SOLUTION
   
  Tier works closely with its clients to determine, evaluate and implement an
IT strategy that allows it to rapidly adopt, deploy and transfer emerging
technologies while preserving viable elements of the client's installed IT
base. Tier combines its significant understanding of enterprise-wide IT
systems with its expertise in vertical industries, such as healthcare,
financial services and government services, to provide clients with rapid and
flexible migration solutions to their IT needs. By helping clients to maintain
their core IT systems, Tier believes it provides high value, cost effective,
flexible solutions that minimize the risks associated with system
improvements.     
 
  The Tier Migration Solution is applied to all of the Company's projects.
Initially, the Company assesses a client's existing business processes and
clearly defines the scope of the project, including a determination of the
client's expectations for quantifiable business improvement. The Company then
analyzes the client's existing IT system to determine which areas would
benefit the most from the application of new technologies. When this
assessment is completed, Tier develops a specific IT strategy that uses a
system architecture consistent with the client's existing environment. Tier
then implements the recommended IT strategy. Throughout all phases, Tier's
risk management committee regularly evaluates the risks inherent in the
project. If the risk management committee detects areas of concern, it
investigates the matter at an early stage and takes appropriate corrective
action to mitigate potential costs and delays.
 
STRATEGY
 
  The Company seeks to become the leading provider of comprehensive IT
migration solutions to Fortune 1000 companies and large government entities.
The Company's strategy includes the following elements:
 
  Concentrate on Migration Opportunities. The Company focuses on the migration
of enterprise-wide IT systems to leading edge technologies for Fortune 1000
companies and large government entities. The Company maintains proficiency in
relevant mainstream and legacy technologies, while also developing expertise
in high demand, emerging technologies that are expected to facilitate the
Company's development and deployment of IT solutions. This strategy allows
Tier to function effectively in open architecture IT environments and to
rapidly adopt, deploy and transfer emerging technologies within existing IT
systems.
 
  Develop Strategic Partnerships. The Company develops strategic partnerships
with service and technology providers pursuant to which Tier becomes the
exclusive or preferred system integrator related to that provider's products
or services within specific market segments or geographic areas. These
relationships offer Tier identifiable revenue opportunities. The Company
believes these relationships provide a number of competitive advantages,
including (i) enabling the Company to broaden its client base; (ii)
maintaining the Company's technological leadership through the deployment of
leading edge applications; and (iii) allowing the Company to project its
staffing needs and more fully maximize employee utilization.
   
  Pursue Strategic Acquisitions. Tier considers potential acquisitions which
may expand the Company's presence in key geographic or vertical marketplaces,
supplement the Company's technical scope or industry expertise or allow it to
acquire additional human resources or strategic client relationships. Given
the highly fragmented nature of the IT services marketplace, the Company
believes significant acquisition opportunities exists. Since December 1996,
Tier has acquired five IT service providers in order to add three domestic and
two international locations, broaden the Company's technical expertise in
areas such as Java and expand its professional resources by 73 IT consultants.
    
  Expand in Key Vertical Markets. The Company intends to increase its client
base and leverage its expertise by focusing its sales, marketing and
development efforts on high-value opportunities in certain vertical markets,
such as healthcare, government services, financial services, transportation
and
 
                                      25
<PAGE>
 
   
telecommunications. Within those markets, Tier has developed expertise in
areas such as child welfare services, child support services and procurement
processes. The Company believes that large organizations with intensive
information processing needs provide the best near-term market opportunities
for the Company's services.     
   
  Expand Geographic Presence. The Company intends to expand its operations by
opening additional branches in targeted domestic and international locations
to augment its current operations in the United States, Australia and the
United Kingdom. Tier integrates domestic and multi-national resources to
deliver timely, cost-effective IT solutions on a local level. By expanding its
geographic presence, the Company has increased its access to international
labor markets and is able to compete more effectively for highly skilled
employees who have particular geographic preferences. The Company believes
that the local delivery of services is a significant differentiating factor
among IT service providers.     
 
  Attract Highly Skilled Employees. The Company maintains programs and
personnel to identify, hire, train and retain highly skilled IT professionals
because it believes these professionals are a critical element in its ability
to deliver high quality services to clients. The Company offers competitive
compensation and benefits including stock option and other stock-based awards,
and has developed a career advancement program that offers employees career
enrichment opportunities, individualized up-training and cross-training
programs, on-the-job learning opportunities and annual training allowances.
 
SERVICES AND METHODOLOGY
 
  The Company provides IT consulting, application development and software
engineering services which facilitate the migration of its clients' existing
IT systems to leading edge technologies. These services are typically provided
on an enterprise-wide basis. Tier's methodology for providing migration
services combines the ability to evaluate or "score" the efficacy of the
client's imbedded IT capital in comparison to its stated business goals, with
a formal risk assessment program to manage and benchmark projects on an on-
going basis. Tier maintains a high level of vertical market and industry
expertise. As a result the Company is able to understand the environment and
business rules in which its clients operate. This approach allows Tier to
retain, reuse, repeat and distribute its experiential knowledge throughout the
Company and to achieve significant improvements in cost, quality and time to
deployment on client projects.
 
 Services
 
  The Company seeks to rapidly implement cost-effective IT solutions through a
flexible combination of one or more of the following services:
 
  Custom Build. The Company often custom builds an IT solution or component
for the client. The Company has developed custom applications in several
vertical markets, including healthcare, financial services, transportation and
consumer products, using advanced languages such as Java, Forte, PowerBuilder
and Composer. The Company's technical professionals have implemented custom
applications on a variety of platforms and working environments, such as
mainframe, UNIX and Windows NT, using a number of databases, including Oracle,
Sybase, DB2 and Informix. Tier has also developed Internet/intranet, data
warehousing and e-commerce applications, as well as applications in the more
established mainframe and client/server environments.
 
  Repeatable Transfer Solution. In some situations, the Company identifies
existing, transferable IT applications or components that satisfy a portion of
the client's needs. Tier addresses the client's remaining functional elements
through either custom built applications or packaged software. Transfer
solutions greatly shorten the development cycle by providing a working system
as the starting point for the IT solution. For example, between government
agencies, the Company has successfully transferred components of IT systems
that it has built to solve complex child support and welfare requirements.
 
                                      26
<PAGE>
 
  Packaged Software. When the most appropriate solution for a client is a
commercially available application package, the Company evaluates, recommends,
implements and integrates enterprise-level package applications from providers
such as NovaSoft Systems, Inc., Ariba Technologies, Inc. and Requisite
Technology, Inc. The Company has developed expertise with commercial
applications in areas such as workflow process management, document
management, operations resource management, e-commerce and procurement. Tier's
package implementation practices are organized around specific application
areas such as healthcare, financial services, transportation and procurement.
 
 Methodology
 
  The Company has developed the Tier Migration Solution over numerous client
engagements and relies on this methodology to provide services in various
industries and technical environments. The four-phase scaleable, repeatable
and leverageable methodology is modular in design and the various phases can
be tailored depending on the scope of a client's needs.
   
        [Graphic: A representation of the Tier migration solution methodology,
        indicating each of its four phases, Business Assessment and Scoping,
        Application Effectiveness Scoping, IT Strategy, Architecture and
        Prototyping and Information Technology Implementation.]    

   
  Phase I - Business Assessment and Scoping. The Company establishes the scope
of each project and determines expectations for quantifiable business
improvement. The Company assesses the client's current business processes,
identifies improvement opportunities and inventories the existing IT
applications and systems. Tier consultants bring industry and technical
expertise to each engagement and employ current business engineering
techniques, such as workflow analysis, process mapping, use-case analysis and
business rules definition. Typically, Tier consultants interview key
management personnel, lead group discussions, conduct workshops, review
existing business process documentation and inventory the existing application
portfolio. The work product is a business requirements and scope document that
provides a clear charter for the project and a risk management assessment map
to measure project performance throughout the project's life cycle.     
 
                                      27
<PAGE>
 
  Phase II - Application Effectiveness Scoring. The Company develops a
technology portfolio analysis to determine how best to leverage the client's
capital investment in its existing IT system. Tier conducts an in-depth
analysis of the existing IT application portfolio using a qualitative method
of "scoring" to determine which areas would benefit most from the application
of new technologies. The resulting matrix correlates the client's business
functions with the most suitable IT solution. Once agreed to by the client,
the application scoring matrix becomes a roadmap to assist in determining
whether to replace or re-use components of the client's existing IT system.
 
  Phase III - IT Strategy, Architecture and Prototyping. The Company develops
a specific IT strategy to address the development, transfer or acquisition of
new IT solutions and their integration into the client's existing business
environment. Tier analyzes "buy versus build" opportunities, evaluates
potential commercial software products and identifies appropriate software
development techniques. Tier may model critical business rules to test the
underlying assumptions of the IT solution and often prepares an early look-
and-feel prototype to allow the user to visualize the resulting integrated IT
environment. Ultimately, Tier provides clients with a defined IT architecture
designed to meet the client's expectations specified at the beginning of the
engagement.
 
  Phase IV - Information Technology Implementation. Tier implements the IT
solution. The Company employs rapid IT processes and incorporates the
Company's collective experience in managing enterprise-wide IT projects in
areas such as packaged software implementation, custom software development,
quality assurance and testing, systems integration, client testing and
acceptance, implementation and help desk support. The output of this final
phase is an implemented IT solution set. Following installation, the Company
and the client conduct a post-project assessment to evaluate the effectiveness
of the new IT solution against the business improvement goals established in
Phase I. In addition, the Company provides post-implementation services, such
as on-going software maintenance and enhancements, help desk support and
training of end users and in-house IT staff.
 
  Across all four phases of its methodology, Tier employs a comprehensive risk
management process. The Company believes that its emphasis on risk management
is a critical component of its methodology, particularly in a market that
increasingly demands service providers to undertake large scale projects while
maintaining a high success rate. Given the importance of this process, the
Company's risk management committee (the "Committee") includes the Company's
Chief Executive, Operating and Financial Officers. Using the risk management
assessment map developed in Phase I of Tier's Migration Solution, the
Committee evaluates projects on a regular basis against a checklist of risk
factors and assigns a status that determines the frequency of intervention and
review required. The Committee focuses on the following risk factors: size of
revenue and credit exposure to the Company, number of resources employed,
progress against defined project milestones, clarity of user expectations,
definition of project scope, use of new technology, effectiveness of project
management personnel and other quantitative and qualitative measures as may be
appropriate to a particular project. If the Committee detects areas of
concern, it investigates the matter at an early stage and takes appropriate
corrective action to mitigate potential costs and delays.
 
REPRESENTATIVE ENGAGEMENTS
 
  The following are examples of Tier's IT migration engagements:
   
  Healthcare Process Improvement. In an engagement for a national HMO, Tier
completed the implementation of a Medicare compliance system that reduced the
HMO's application process cycle time from six weeks to two days, which in turn
accelerated its Medicare collections. By adding an improved input and analysis
"front end" to the HMO's existing insurance claims processing system, Tier
leveraged the most beneficial components of the HMO's existing technology
infrastructure. In a second project for the HMO, Tier developed an enterprise-
wide budget development system to allow the HMO's nationwide staff of
controllers, analysts and cost center managers to run financial simulations
and receive real-time feedback.     
 
                                      28
<PAGE>
 
The project increased the quality of the client's budgets and significantly
reduced their development time. The new system was integrated with the HMO's
existing accounting and finance applications to provide a financial control
solution at a fraction of the cost of a complete system replacement. Over a
four-year period, Tier has completed more than a dozen strategic projects for
the HMO.
   
  International Risk Management Application. Tier is currently performing a
multi-national engagement for a worldwide financial services and information
company to develop a global check authorization system. This $10 million, 18-
month project encompasses the redesign of business processes, a full migration
of application software, specifications for the selective replacement of
system hardware and the creation of a data warehouse for decision support.
Tier was chosen over its competitors for its industry expertise in process
redesign, simulation modeling, technical architecture, database design, rapid
application development, project management and its ability to rapidly
implement this complex project.     
 
  Child Welfare Case Management Solution. Tier, in conjunction with Unisys,
developed and implemented an integrated child welfare case management system
for a state government's health and human services department. By focusing on
improved workflow, integrated data management and the use of distributed
client/server technology, the Company believes the case management system will
increase the amount of time available for the case worker to work directly
with families, while also improving the quality and timeliness of information.
The case management system supports the state's child protective services
intake hotline, report investigation, case planning and outcome management and
financial and staff management.
 
  Transportation System Solutions. Tier successfully completed a multi-phased
$1.3 million migration project for a state's department of transportation to
develop a fleet management system, including a preventive maintenance program
and a mechanized warranty system. The Company's IT solution utilized an
advanced client/server technology and leveraged components from two existing
mainframe systems. The system provides complete fleet management services to
over 200 users throughout the state. The client performed an extensive cost-
benefit analysis prior to developing the system and determined that the
improved service of the equipment will pay for the system within two years.
Tier is currently performing an $8.8 million, multi-phased client/server
project to redesign the department's multiple legacy transportation management
systems into one highly integrated decision making tool.
 
SALES AND MARKETING
   
  The Company markets and sells its services through a direct sales force. As
of September 30, 1997, Tier employed ten full-time, dedicated sales and
marketing staff. In addition, the Company's senior management is closely
involved in a significant portion of the Company's sales and marketing
activities. Most of the Company's sales professionals have extensive work
experience in the IT industry, often as strategic IT consultants or managers.
In order to more clearly define the delivery of its services and to reflect
the needs of its clients, the Company has organized its sales and marketing
effort into three strategic business units ("SBUs"): (i) Commercial Services,
which targets custom software development and transfer solutions for
commercial markets; (ii) Government Services, which targets custom software
development and transfer solutions in the fast-growing health and human
services and state strategic IT markets; and (iii) Business Solutions, which
targets packaged software implementation services for both commercial and
governmental markets.     
 
  The Company's focus on the vertical markets defined by these SBUs broadens
its knowledge and expertise in these selected industries and generates
additional client engagements. As a result of its focused sales channel
approach, the Company believes that it is able to penetrate markets quickly
and with lower sales acquisition costs.
 
  The sales team derives leads through (i) strategic partnerships with
software providers under which the Company delivers services on an exclusive
or preferred basis within specific geographic or vertical markets; (ii)
industry networking and referrals from existing clients; (iii) government
requests for proposals; (iv) directed sales activities identified by other
strategic business units within the Company; and (v) a national marketing
program. The Company believes that its use of these multiple sales and
marketing activities results in a shorter sales cycle than generally
experienced by other providers.

  The Company's marketing program includes targeted software industry trade
shows; joint marketing with software providers through strategic partnership
arrangements; participation in user groups; provision of speakers to
technology conferences; publication of white papers, articles and direct
client newsletters; and distribution of marketing materials through print
advertising, direct mail, media and public relations announcements.
 
CLIENTS
   
  The Company's clients consist primarily of Fortune 1000 companies with
information-intensive businesses and government entities with large volume
information and technology needs. Tier's sales and marketing objective is to
develop relationships with clients which result in both repeat and long-term
engagements. Of the Company's clients with revenues in excess of $50,000 in
fiscal 1996, 88% (15 of 17) were clients in the nine-month fiscal year ended
September 30, 1997 and generated revenues in excess of $50,000 in such
subsequent period.     
   
  Tier has derived, and believes that it will continue to derive, a
significant portion of its revenues from a small number of large clients, many
of which engage the Company on a number of projects. For the nine-month fiscal
year ended September 30, 1997, the State of Missouri, Kaiser and Unisys
Corporation accounted for 22.3%, 21.1% and 19.7% of the Company's revenues,
respectively. Kaiser accounted for 59.3% and 68.1% of the Company's revenues
in 1996 and 1995, respectively, while Unisys accounted for 14.6% of the
Company's revenues in 1996.

* Indicates that the Company was engaged as a subcontractor for certain
  project engagements for the client.
 
  In its Government Services SBU, the Company sometimes obtains project
engagements through prime contractors such as Unisys. For example, in a
project for the State of Arizona, Tier was responsible for the complete IT
strategy, architecture, design, software development and testing as a
subcontractor to Unisys, which was engaged by the State to implement a new
child welfare system. The Company believes that it has been able to secure
large, complex government projects with low acquisition costs by capitalizing
on the reputation, marketing infrastructure and government relationships of
these prime contractors, while
 
                                      30
<PAGE>
 
at the same time allowing the prime contractors to leverage Tier's IT
competency in their bid proposals. When Unisys bid for the Australian National
Child Support System, Unisys relied on Tier as an integral part of the team
responsible for securing the engagement. The Tier/Unisys team ultimately was
awarded the contract for the entire system. The Company will continue to seek
subcontracting relationships with parties such as Unisys.
 
  Until fiscal 1997, Company revenues were generated primarily through Tier's
domestic operations. In the nine-month fiscal year ended September 30, 1997,
the Company's operations in Australia and the United Kingdom represented 9.1%
and 4.6% of revenues, respectively. See Note 10 to Notes to Consolidated
Financial Statements.
 
HUMAN RESOURCES
 
  Tier's approach to managing human resources has allowed the Company to meet
its staffing needs while also achieving a low level of employee turnover. As
of September 30, 1997, the Company had a workforce of 231, including 146
salaried IT consultants, ten sales/marketing employees and 28
administrative/accounting employees. In addition to its employee IT
consultants, the Company has retained 47 hourly contractors to supplement its
IT workforce. As of September 30, 1997, approximately 75.6% of the Company's
IT consultants were salaried and the remaining 24.4% were hourly contractors.
Of the Company's total workforce, 80.1%, 10.8% and 9.1% are located in the
United States, Australia and the United Kingdom, respectively.
   
  The Company employs two Senior Directors of Recruiting and seven full-time
recruiters who pursue a three level employee-sourcing strategy. The primary
sources include employee referrals, job fairs, Internet job postings and
direct recruiting. Tier also has established national and international
sources through preferred-rate partnerships with recruiting suppliers. If peak
staffing demand exceeds these resources, the Company engages recruiting
agencies on a contingent basis at market rates. The Company attracts and
retains employees by offering significant technical training opportunities, a
stock option award program and a competitive benefits and compensation
package. Given the rapid pace of technological evolution, the Company
recognizes that skill obsolescence is a fundamental concern for IT
professionals. As a key component of the Company's employee retention program,
Tier has developed a program that enables each employee to specify their
career goals and develop a plan to achieve those goals. The program includes
specific career enrichment opportunities, individualized up-training and
cross-training, on-the-job learning opportunities and challenging assignments.
As part of the program, each consultant works under the guidance of a practice
manager and senior technology expert within their practice. All employees
receive annual training allowances which can be utilized for an array of
career development needs such as internal and external seminars and computer-
based training. The Company believes that there is a shortage of, and
significant competition for, IT professionals and that its future success is
highly dependent upon its ability to attract, train, motivate and retain
skilled IT consultants with the advanced technical skills necessary to perform
the services offered by the Company.     
 
COMPETITION
 
  The IT services market is highly competitive and is served by numerous
international, national and local firms. Market participants include systems
consulting and integration firms, including national accounting firms and
related entities, the internal information systems groups of its prospective
clients, professional services companies, hardware and application software
vendors, and divisions of large integrated technology companies and
outsourcing companies. Many of these competitors have significantly greater
financial, technical and marketing resources, generate greater revenues and
have greater name recognition than the Company. In addition, there are
relatively low barriers to entry into the IT services market, and the Company
has faced, and expects to continue to face, additional competition from new
entrants into the IT services market.
 
                                      31
<PAGE>
 
  The Company believes that the principal competitive factors in the IT
services market include reputation, project management expertise, industry
expertise, speed of development and implementation, technical expertise,
competitive pricing and the ability to deliver results on a fixed price as
well as a time and materials basis. The Company believes that its ability to
compete also depends in part on a number of competitive factors outside its
control, including the ability of its clients or competitors to hire, retain
and motivate project managers and other senior technical staff; the ownership
by competitors of software used by potential clients; the price at which
others offer comparable services; the ability of its clients to perform the
services themselves; and the extent of its competitors' responsiveness to
client needs. There can be no assurance that the Company will be able to
compete effectively on pricing or other requirements with current and future
competitors or that competitive pressures will not cause the Company's
revenues or income to decline or otherwise materially adversely affect its
business, financial condition and results of operations.
 
INTELLECTUAL PROPERTY RIGHTS
 
  Tier's success has resulted, in part, from its methodologies and other
proprietary intellectual property rights. The Company relies upon a
combination of nondisclosure and other contractual arrangements and trade
secret, copyright and trademark laws to protect its proprietary rights and the
proprietary rights of third parties from whom the Company licenses
intellectual property. The Company enters into confidentiality agreements with
its employees and limits distribution of proprietary information. There can be
no assurance that the steps taken by the Company in this regard will be
adequate to deter the misappropriation of proprietary information or that the
Company will be able to detect unauthorized use of this information and take
appropriate steps to enforce its intellectual property rights.
 
  Software developed by Tier in connection with a client engagement is
typically assigned to the client. In limited situations, the Company may
retain ownership, or obtain a license from its client, which permits Tier or a
third party to market the software for the joint benefit of the client and
Tier or for the sole benefit of Tier.
 
FACILITIES
   
  Tier's principal executive offices are located at 1350 Treat Boulevard,
Suite 250, Walnut Creek, California. The Company's lease on these premises
covers approximately 9,745 square feet and expires November 30, 2001. The
Company also leases facilities in Atlanta, Georgia; Boston, Massachusetts;
Chicago, Illinois; Jacksonville, Florida; Jefferson City, Missouri; Phoenix,
Arizona; Birmingham, England; Canberra, Australia; and Sydney, Australia. Tier
anticipates that additional space will be required as its business expands and
believes that it will be able to obtain suitable space as needed.     
 
LEGAL PROCEEDINGS
 
  The Company is not currently a party to any legal proceedings.

EMPLOYMENT AGREEMENTS
   
  In December 1996, the Company entered into a three-year employment agreement
with James L. Bildner, the Company's Chairman of the Board and Chief Executive
Officer. The agreement provides for an annual base salary of $325,000,
quarterly incentive compensation totaling at least $100,000 per year upon the
achievement of certain targeted levels of earnings by the Company, and
benefits under the Company's benefit plans. Mr. Bildner is also entitled to a
$50,000 relocation loan, which bears interest at 5.75% per annum and is
forgivable over a three-year period beginning on December 31, 1996 (the
"Relocation Loan"), and a monthly housing allowance of $2,750 (for a three-
year period beginning December 31, 1996), payable in advance upon request of
Mr. Bildner. The agreement also provides, among other things, that if Mr.
Bildner's employment with the Company is terminated (i) by the Company for
cause (as defined in the agreement), other than Mr. Bildner's conviction of a
felony, the Company will pay to Mr. Bildner his base salary and benefits for a
period of 24 months from the date of termination; or (ii) by the Company
without cause or by Mr. Bildner for good reason (as defined in the agreement),
the outstanding principal balance and accrued interest under the Relocation
Loan will be forgiven, all outstanding unvested options held by Mr. Bildner
will immediately vest and the Company will pay Mr. Bildner a lump sum amount
equal to the discounted present value of 24 months of a base salary plus 100%
of the maximum amount of incentive compensation Mr. Bildner could have earned
during the year in which the termination occurs. Benefits substantially
similar to those set forth in clause (ii) above are provided in the event of
termination of Mr. Bildner's employment due to death or disability and, upon
any event of termination, the Company will take all action required to release
Mr. Bildner from any personal guaranties of Company indebtedness. Pursuant to
this agreement Mr. Bildner also received an option to purchase 80,000 shares
of Class A Common Stock and 120,000 shares of Class B Common Stock at an
exercise price equal to 100% of the fair market value of such stock on the
date of grant, which vested immediately. He also received an option for
120,000 shares of Class A Common Stock and 180,000 shares of Class B Common
Stock, which vests ratably on the first three annual anniversaries of the date
of grant, except that 33.3% of the option vests upon completion of this
offering (the "Bildner Repurchaseable Option"). The Bildner Repurchaseable
Option was exercised by Mr. Bildner prior to vesting and is subject to a right
of repurchase by the Company at its exercise price until vested. Mr. Bildner's
employment agreement was amended in September 1997 to extend its term through

  In December 1996, the Company entered into a three-year employment agreement
with William G. Barton, the Company's President and Chief Operating Officer.
The agreement provides for an annual base salary of $225,000, quarterly
incentive compensation totaling at least $75,000 per year upon the achievement
of certain targeted levels of earnings by the Company, and benefits under the
Company's benefit plans. Mr. Barton is also entitled to an education loan up
to $50,000, which bears interest at 5.75% per annum and is forgivable over
approximately three years (the "Education Loan"). The agreement also provides,
among other things, that if Mr. Barton's employment with the Company is
terminated (i) by the Company for cause (as defined in the agreement), other
than Mr. Barton's conviction of a felony, the Company will pay to Mr. Barton
his base salary and benefits for a period of 24 months from the date of
termination; or (ii) by the Company without cause or by Mr. Barton for good
reason (as defined in the agreement), the outstanding principal balance and
accrued interest under the Education Loan will be forgiven, all outstanding
unvested options held by Mr. Barton will immediately vest and the Company will
pay Mr. Barton a lump sum amount equal to the discounted present value of 24
months of a base salary plus 100% of the maximum amount of incentive
compensation Mr. Barton could have earned during the year in which the
termination occurs. Benefits substantially similar to those set forth in
clause (ii) above are provided in the event of termination of Mr. Barton's
employment due to death or disability and, upon any event of termination, the
Company will take all action required to release Mr. Barton from any personal
guaranties of Company indebtedness. Pursuant to this agreement, Mr. Barton
received an option to purchase 120,000 shares of Class A Common Stock and
180,000 shares of Class B Common Stock, at an exercise price equal to 110% of
the fair market value of such stock on the date of grant, which vests ratably
on the first three annual anniversaries of the date of grant, except that
33.3% of the option vests upon completion of this offering (the "Barton
Repurchaseable Option"). The Barton Repurchaseable Option was exercised by Mr.
Barton prior to vesting and is subject to a right of repurchase by the Company
at its exercise price until vested. Mr. Barton's employment agreement was
amended in September 1997 to extend its term through August 1, 2001. See "--
 Executive Compensation" and "Certain Transactions."     
   
  In February 1997, the Company entered into an employment agreement with
George K. Ross, the Company's Senior Vice President and Chief Financial
Officer. The agreement terminates August 1, 2001 and provides for an annual
base salary of $175,000 and quarterly incentive compensation totaling at least
$25,000 per year upon the achievement of certain targeted levels of earnings
by the Company. In the event the agreement is terminated by Mr. Ross for good
reason (as defined in the agreement) or by the Company other than for cause
(as defined in the agreement), Mr. Ross will be entitled to receive his full
salary for a period of six months from the date of such termination and a pro
rata portion of the incentive compensation for which he could be eligible
during the year the termination occurs. The agreement also provides that the
Company offer an unsecured relocation loan of up to $20,000, bearing simple
interest at 5.81% per annum, which amount shall be forgiven over three years
so long as Mr. Ross remains employed by the Company. Pursuant to this
agreement, Mr. Ross received an option to purchase 105,000 shares of Class B
Common Stock, at an exercise price equal to 100% of the fair market value of
such stock on the date of grant, which option vests ratably on the first three
annual anniversaries of the grant. In the event of a sale of substantially all
of the assets of the Company, a change in control of the Company or upon the
termination of James L. Bildner as Chief Executive Officer of the Company, the
option fully vests immediately. See "-- Executive Compensation" and "Certain
Transactions."

       OPTION GRANTS IN THE TWELVE-MONTH PERIOD ENDED SEPTEMBER 30, 1997
 
 
- --------
(1) Based on an aggregate of 2,783,075 options granted to employees in the
    twelve-month period ended September 30, 1997, including options granted to
    the Named Executive Officers.
   
(2) The exercise price equals or exceeds the fair market value of the stock as
    of the grant date as determined by the Board of Directors after
    consideration of a number of factors, including, but not limited to, the
    Company's financial performance, the price of shares of equity securities
    sold to or purchased by outside investors and third-party appraisals.     
   
(3) The amounts shown are hypothetical gains based on the indicated assumed
    rates of appreciation of the Class B Common Stock based on an assumed
    initial public offering price of $10.00 per share, compounded annually for
    the term of the option. Actual gains, if any, on stock option exercises
    are dependent on the future performance of the Class B Common Stock and
    overall stock market conditions. There can be no assurance that the Class
    B Common Stock will appreciate at any particular rate, or at all, in
    future years.     
(4) Options vest 40% on the date of grant and then 20% on each of the first
    three anniversaries of the date of grant; provided, however, that 20% vest
    upon completion of this offering. Certain of these options were exercised
    in advance of vesting, subject to a right of repurchase by the Company at
    such option's exercise price.
(5) Options vest 33.3% on each of the first three anniversaries of the date of
    the option; provided, however, that 33.3% vest immediately upon completion
    of this offering with the remaining shares vesting over the scheduled
    period. Certain of these options were exercised in advance of vesting,
    subject to a right of repurchase by the Company at such option's exercise
    price.
(6) Options vest 25% on each of the first four anniversaries of the date of
    grant.
(7) Options vest 33.3% on each of the first three anniversaries of the date of
    grant.
(8) Options vest 25% on each of the first four anniversaries of the date of
    grant.

(1) The value realized is based on the difference between the market price at
    the time of exercise of the options and the applicable exercise price.
   
(2) The value of unexercised in-the-money options is calculated based on an
    assumed initial public offering price of $10.00 per share. Amounts
    reflected are based on such estimated fair market value minus the
    aggregate exercise price and do not necessarily reflect that the optionee
    sold such stock.     
 
INCENTIVE PLANS
 
  Amended and Restated 1996 Equity Incentive Plan. The Company's Amended and
Restated 1996 Equity Incentive Plan (the "Plan") provides for grants to
employees of incentive stock options within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended, and for grants to employees,
directors and consultants of non-qualified stock options, restricted stock and
stock bonuses. The purposes of the Plan are to attract and retain the best
available personnel for positions of substantial responsibility, to provide
additional incentives to the employees and consultants of the Company and to
promote business.
 
  In October 1997, the Company amended the Plan to authorize a total of
2,989,333 shares of Class B Common Stock for issuance pursuant to the Plan. As
of September 30, 1997, options to purchase 1,713,075 shares of Class B Common
Stock were outstanding at a weighted average exercise price of $3.94, and upon
the closing of this offering 1,246,258 shares will be available for future
grant under the Plan.
   
  The Plan is administered by the Compensation Committee of the Board of
Directors. The Compensation Committee has the power to determine the terms of
the options granted, including the exercise price, the number of shares
subject to the option and the exercisability thereof, and the form of
consideration payable upon exercise. Except as permitted by the Compensation
Committee, options granted under the Plan are not transferable by the
optionee, and each option is exercisable during the lifetime of the optionee
only by such optionee. The exercise price of all incentive stock options
granted under the Plan must be at least equal to the fair market value of the
Class B Common Stock on the date of grant. The exercise price of non-qualified
stock options may not be less than 85% of the fair market value of a share of
Class B Common Stock on the date of grant. With respect to any optionee who
owns 10% or more of the Company's outstanding capital stock, the exercise
price of any incentive stock option granted to such optionee must equal or
exceed 110% of the fair market value of the Class B Common Stock on the grant
date and the term of the option must not exceed five years. The aggregate fair
market value of the Class B Common Stock (determined at the time the option is
granted) with respect to which incentive stock options granted to an
individual first become exercisable in any calendar year shall not exceed
$100,000. No more than 100,000     
 
                                      39
<PAGE>
 
   
shares may be granted pursuant to options to any one person under the Plan in
any single fiscal year. The term of all options (other than options granted to
any optionee who owns 10% or more of the Company's outstanding capital stock)
may not exceed ten years.     
 
  The Compensation Committee may grant restricted shares, i.e., shares of Class
B Common Stock which are subject to transfer restrictions determined by the
Compensation Committee and subject to substantial risk of forfeiture unless and
until specific conditions established by the Compensation Committee at the time
of grant are met. Such conditions may be based on continuing employment or
achievement of pre-established performance goals, or both, as determined by the
Compensation Committee.
 
  The Plan also authorizes the Compensation Committee to award or to offer
bonuses of shares of Class B Common Stock, either restricted or unrestricted,
and as current or deferred compensation, in lieu of all or any portion of the
cash compensation to which the employee is entitled, for a number of shares
having a value on the grant date equal to the amount of such cash compensation.
 
  Stock options and performance-based restricted stock granted under the Plan
are intended to be "performance-based compensation" and therefore not subject
to the deduction limitation of Code Section 162(m).
 
  The Company accounts for employee stock options in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" and
in the year ended December 31, 1996 adopted the disclosure-only alternative
described in Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation." Restricted and unrestricted stock bonuses under
the Plan would, however, involve an earnings charge.
   
  The Plan was approved by the Board of Directors and shareholders and became
effective on February 10, 1997. Unless terminated sooner, the Plan will
terminate automatically on February 9, 2007. The Board of Directors has the
authority to amend, suspend or terminate the Plan, subject to any required
shareholder approval under applicable law. Notwithstanding the foregoing, no
amendment, suspension or termination of the Plan shall alter or impair an
interest granted to a beneficiary under the Plan without such beneficiary's
written consent.     
 
  Employee Stock Purchase Plan. In October 1997, the Company adopted an
Employee Stock Purchase Plan (the "Purchase Plan"). A total of 100,000 shares
of Class B Common Stock is reserved for issuance under the Purchase Plan. The
Purchase Plan, which is intended to qualify as an "employee stock purchase
plan" under Section 423 of the Internal Revenue Code, permits eligible
employees to purchase shares of Class B Common Stock through payroll
deductions. Eligible employees may select a rate of payroll deduction between
1% and 10% of their cash compensation, but not more than 500 shares may be
purchased per participant on any purchase date. The price of stock purchased
under the purchase plan will be 85% of the lower of the fair market value of
the Common Stock at the beginning or the end of the six-month purchase period.
Employees will generally be eligible to participate if they are employed by the
Company on the beginning of a purchase period. Employees may end their
participation in the Purchase Plan at any time, and participation ends
automatically on termination of employment with the Company.
   
  The Board of Directors may amend, suspend or terminate the Purchase Plan at
any time, to be effective immediately after the close of any purchase period.
However, the Board of Directors may not, without shareholder approval,
materially increase the number of shares of Class B Common Stock available for
issuance, alter the purchase price formula so as to reduce the purchase price
payable for shares of Class B Common Stock, or materially modify the
eligibility requirements for participation. The Purchase Plan will in all
events terminate on September 30, 2007, unless terminated earlier by the Board
of Directors.     
 
  401(k) Plan. The Company maintains a 401(k) profit-sharing and deferred
contribution plan (the "401(k) Plan"). All employees of the Company who have
reached 21 years of age and who have
 
                                       40
<PAGE>
 
completed one month of employment are eligible to participate in the 401(k)
Plan, pursuant to which each participant may contribute up to 15% of eligible
compensation (up to a statutorily prescribed annual limit of $9,500 in 1997).
Although the Company is permitted to contribute to the 401(k) Plan, it has not
made such contributions in the past. Participants vest in Company
contributions, if any, ratably on the third through seventh anniversaries of
the Company's contribution. All amounts contributed by employee participants
and earnings on these contributions are fully vested at all times. Employee
participants may elect to invest their contributions in various established
funds.

                             CERTAIN TRANSACTIONS
 
  The Company retained the consulting services of Argus Corporation ("Argus"),
a consulting firm for which the Company's Chairman of the Board and Chief
Executive Officer, James L. Bildner, was then a principal, for payments
aggregating $198,890 for services rendered during the year ended December 31,
1996.
   
  The Company has made loans to certain employees in connection with their
exercise of stock options, the payment of taxes associated with those
exercises, relocation and housing expenses, educational expenses and personal
purposes. All loans are made pursuant to full-recourse, interest-bearing
promissory notes and certain notes are secured by a pledge of Common Stock
held by the employee. Interest rates range from 5.75% to 9.00% and vary based
on the term of the loan and its date of origination. The loans have ten-year
terms, with the exception of forgivable loans which have three-year terms and
are typically forgiven ratably over the note's term so long as the employee
remains with the Company. Loans to Mr. Bildner total $1,859,302, of which
amount $135,250 plus accrued interest may be forgiven. Loans to Mr. Barton
total $1,164,558, of which amount $47,677 plus accrued interest may be
forgiven. Loans to Mr. Ross total $20,000, which amount plus accrued interest
may be forgiven in its entirety. Loans to Mr. Latham total $10,000, which
amount plus accrued interest may be forgiven in its entirety. See
"Management -- Employment Agreements."     
   
  The Company has entered into employment agreements with Mr. Bildner, Mr.
Barton, its President and Chief Operating Officer, and Mr. Ross, its Senior
Vice President and Chief Financial Officer. See "Management -- Employment
Agreements."     
   
  In July 1997, certain officers, directors and more than 5% shareholders
participated in the private placement of shares of the Company's Series A
Preferred Stock (the "Private Placement"). Messrs. Barton, Cabot, Ross and
Rossetti purchased 9,524, 3,810, 4,762 and 9,524 shares of Series A Preferred
Stock, respectively, at a price of $5.25 per share, which price was determined
based on arm's length negotiations with unaffiliated third parties. The
Private Placement was made pursuant to Rule 506 of Regulation D under the Act.
Upon the closing of this offering, these shares will automatically convert
into an equal number of shares of Class B Common Stock. These shareholders
have identical registration rights to those of other purchasers in the Private
Placement. See "Description of Capital Stock -- Registration Rights."     
   
  In August 1997, the Company entered into an agreement (the "Direct Sale
Agreement") with AH&H Partners Fund Limited Partnership, Wilson Hitchings (who
served as a director of the Company until September 1997), Leon Normand (who
served as a director of the Company until September 1997), Robert Butorac,
James Hinson and Greg Bowen (the "Selling Founders"), wherein the Selling
Founders agreed to sell a total of 95,238 shares of their Class A Common Stock
(which, upon the consummation of the sale converted to an equal number of
shares of Class B Common Stock) to the AH&H Partners Fund Limited Partnership.
Messrs. Hitchings and Normand each received approximately $113,636, before
payment of expenses associated with the transaction. The purchase price was
determined based on arm's length negotiations with unaffiliated third parties.
    
  The Company has entered into indemnification agreements with each of its
directors and executive officers. These agreements provide such persons with
indemnification, to the maximum extent permitted by the Company's Articles or
Bylaws or by the California General Corporation Law, against all expenses,
claims, damages, judgments and other amounts (including amounts paid in
settlement) for which such persons become liable as a result of acting in any
capacity on behalf of the Company, subject to certain limitations.
   
  In August 1996, the Company repurchased 5,000 shares of its common stock
from one of its directors, William C. Lavin, upon his resignation, for a total
of $74,970, which price was determined based on book value per share in
accordance with the terms of his stock purchase agreement. This amount is     
 
                                      42

payable to Mr. Lavin pursuant to the terms of a promissory note. The note
bears interest at 8.25% per annum over five years and principal and interest
thereunder are payable monthly. The description of this transaction does not
reflect the Company's recapitalization, pursuant to which each outstanding
share of common stock was exchanged for 40 shares of Class A Common Stock and
60 shares of Class B Common Stock.

                         DESCRIPTION OF CAPITAL STOCK
   
  The authorized capital stock of the Company consists of 2,304,762 shares of
Class A Common Stock, without par value, 42,600,000 shares of Class B Common
Stock, without par value, and 4,579,047 shares of Preferred Stock. As of
September 30, 1997, there were 2,284,762 shares of Class A Common Stock
outstanding held by ten holders of record, and 3,786,191 shares of Class B
Common Stock outstanding held by 43 holders of record.     
 
CLASS A AND CLASS B COMMON STOCK
   
  Voting Rights. Each share of Class A Common Stock entitles the holder to ten
votes and each share of Class B Common Stock entitles the holder to one vote
on all matters submitted to a vote of the shareholders. Except as described
below, holders of the Class A Common Stock and Class B Common Stock vote
together as a single class on all matters presented for a vote of the
shareholders. However, holders of the Class B Common Stock, voting as a
separate class, elect that number of Directors which is the largest integral
number which is less than 50% of the authorized number of Directors (i.e. two
of the present five directors) (the "Class B Specified Voting Right"). The
holders of Class A and Class B Common Stock, voting together, elect the
remaining members of the Board (i.e. three of the present five directors).
Immediately following this offering, the holders of Class A Common Stock will
retain effective control, and will continue to direct the business, management
and policies of the Company through holding 69.6% of the combined voting power
of the outstanding Class A and Class B Common Stock and the ability to elect
three of the currently authorized five members of the Board of Directors. The
holders of the Class A Common Stock also hold a number of shares of Class B
Common Stock that will represent 45.4% of the shares of Class B Common Stock
outstanding after this offering.     
   
  Directors may be removed with or without cause by the holders of the class
of stock that elected them or, to the extent permitted by applicable law, with
cause by the Board of Directors. A vacancy on the Board created by the removal
or resignation of a director or an increase in the authorized number of
directors may be filled either by directors in office or, if the directors
have not filled the vacancy, by the shareholders. Elections or appointments
for any such vacancies shall be made in accordance with the Class B Specified
Voting Right.     
   
  Voting Trust. All of the current holders of Class A Common Stock (the
"Beneficiaries") have transferred their Class A Common Stock into a Voting
Trust. James L. Bildner and William G. Barton are the trustees of the Voting
Trust (the "Trustees") and have the exclusive right to vote all shares of
Class A Common Stock held in the Voting Trust. Shares held in the Voting Trust
are evidenced by a voting trust certificate. The Voting Trust has a term of
ten years and is renewable by consent of the Beneficiaries and the Trustees
during the last two years of the original or an extended term. The Voting
Trust terminates upon the earlier of the expiration of the original or an
extended term or in the event of (i) an agreement of the Trustees to
terminate; or (ii) the death of the sole remaining Trustee, leaving no
incumbent or identified successor.     
   
  Shares of Class A Common Stock transferred between Messrs. Bildner and
Barton remain within the Voting Trust. Shares of Class A Common Stock
transferred by any other Beneficiary, other than transfers of Class A Common
Stock into the Voting Trust or a transfer of such shares from the Voting Trust
back to the person or entity which transferred the shares into the Voting
Trust, will result in the conversion of such shares into an equal number of
shares of Class B Common Stock.     
   
  Buy-Sell Agreement. Messrs. Bildner and Barton have entered into a buy-sell
agreement ("Buy-Sell Agreement") respecting their ownership of shares of Class
A Common Stock. Under the terms of the Buy-Sell Agreement, they each agree,
(i) that for five years from the date of the Buy-Sell Agreement they will not
voluntarily transfer their shares of Class A Common Stock, or their voting
trust certificates, if the transfer would result in a conversion of Class A
Common Stock to Class B Common Stock, and that after five years from the date
of the Buy-Sell Agreement, they grant each other a right of first refusal on
such shares on any such transfer;     
 
                                      45
<PAGE>
 
   
(ii) that on the death of one of them, the other has an obligation to purchase
the shares of Class A Common Stock (or the voting trust certificate for such
shares) of the deceased party; (iii) that they will maintain life insurance
policies at their own expense on each others' lives to fund in part the
obligation to purchase the shares at the death of the other; (iv) that the
Buy-Sell Agreement terminates on the termination of the Voting Trust or if
earlier, on the death of both parties; (v) that the price for the shares of
Class A Common Stock (or the voting trust certificates) is the market price of
the shares of Class B Common Stock on the date that the right or obligation to
purchase arises; and (vi) that there is no restriction on the parties' ability
to amend the Buy-Sell Agreement without the consent of any other person.     
   
  Dividends. Holders of Class A and Class B Common Stock are entitled to
receive dividends at the same rate if, as and when declared by the Board of
Directors of the Company out of any funds legally available therefore, subject
to the dividend rights of any Preferred Stock that may be issued and
outstanding. If a dividend is declared on either class of Common Stock, a
proportionate dividend must be paid to the other. No dividend may be declared
or paid in shares of Class A Common Stock.     
       
  Convertibility. Each share of Class A Common Stock is convertible at any
time at the option of the holder into Class B Common Stock on a share-for-
share basis. Shares of Class A Common Stock will be automatically converted
into shares of Class B Common Stock on the happening of certain transfers
described below. Transfers of shares of Class A Common Stock are also subject
to the terms of the Voting Trust Agreement. The Class B Common Stock has no
conversion rights.
 
  Each share of Class A Common Stock shall automatically be converted into
Class B Common Stock, on a share-for-share basis, in the event that the
beneficial or record ownership of such share of Class A Common Stock shall be
transferred (including, without limitation, by way of gift, settlement, will
or intestacy) to any person or entity except for (i) transfers between Messrs.
Bildner and Barton; or (ii) a transfer of Class A Common Stock into the Voting
Trust, or a transfer of such shares from the Voting Trust back to the person
or entity which transferred the shares into the Voting Trust.
 
  Liquidation Rights. In the event of the liquidation of the Company, after
satisfaction of amounts payable to creditors and distribution to the holders
of outstanding Preferred Stock, if any, of amounts to which they may be
preferentially entitled, holders of the Class A Common Stock and Class B
Common Stock are entitled to share ratably in the assets available for
distribution to the shareholders.
 
  Other Provisions. There are no preemptive rights to subscribe to any
additional securities which the Company may issue and there are no redemption
provisions or sinking fund provisions applicable to the Class A or Class B
Common Stock, nor is either class subject to calls or assessments by the
Company. All outstanding shares are, and all shares to be outstanding upon
completion of this offering will be, legally issued, fully paid and
nonassessable.
 
PREFERRED STOCK
 
  Upon the closing of this offering, all outstanding shares of Series A
Preferred Stock will be converted into 420,953 shares of Class B Common Stock.
See Note 7 of Notes to Consolidated Financial Statements for a description of
currently outstanding Preferred Stock. Following the conversion, the shares
converted will be retired from the number of authorized shares of Preferred
Stock.
 
  Under the Articles of Incorporation, as amended and restated upon the
closing of this offering (the "Restated Articles"), the Board of Directors
shall have the authority, without further action by the shareholders, to issue
up to 4,579,047 shares of Preferred Stock in one or more series and to fix the
rights, preferences, privileges and restrictions granted to or imposed upon
any unissued shares of Preferred Stock and to fix the number of shares
constituting any series and the designations of such series. The issuance of
Preferred Stock with voting or conversion rights could adversely affect the
voting power or other rights of the holders of Common Stock and the likelihood
that such holders will receive dividend payments and payments upon liquidation
may have the effect of delaying, deferring or preventing a change in control
of the Company. The Company has no present intention to issue any Preferred
Stock.

BYLAW PROVISIONS
   
  The Company's Bylaws provide that special meetings of the shareholders may
be called only by the Board of Directors, the Chairman of the Board, the
President, the Chief Executive Officer of the Company, or by one or more
shareholders holding shares entitled to cast not less than 10% of the
aggregate votes entitled to be cast at such meeting. The Bylaws also provide
that any action which may be taken at any meeting of shareholders, subject to
certain exceptions relating to the election of directors, may be taken without
a meeting if written consents approving the action are signed by the holders
of outstanding shares having not less than the minimum number of votes that
would be necessary to take such action at a meeting of shareholders.
Accordingly, immediately following this offering, the holders of Class B
Common Stock will have insufficient voting power, in the aggregate, to call
special meetings of shareholders and the holders of the Class A Common Stock
may take certain actions by written consent without formally convening a
meeting of shareholders and without giving prior notice to the holders of the
Class B Common Stock. The Bylaws provide that shareholders may not bring
business before or nominate directors at a meeting of shareholders unless
certain advance notice requirements are satisfied. In addition, the Articles
and Bylaws provide for the automatic elimination of the cumulative voting
rights of shareholders in the election of directors as soon as the Company has
800 shareholders of record. Without cumulative voting, the holders of a
majority of the voting power of the Common Stock can determine the composition
of the Board of Directors.     
 
REGISTRATION RIGHTS
   
  The holders ("Registration Rights Holders") of 420,953 shares of Class B
Common Stock (upon the conversion of all outstanding shares of Series A
Preferred Stock into an equal number of shares of Class B Common Stock upon
completion of this offering) are entitled to certain rights with respect to
registration of such shares under the Securities Act, pursuant to an
Investors' Rights Agreement dated July 28, 1997. In particular, under certain
circumstances and subject to certain conditions, the Registration Rights
Holders can require the Company to register shares under the Act, which right
becomes exercisable one year from the closing of this offering. The
Registration Rights Holders were also granted certain "piggy-back"
registration rights, whereby on two occasions during the period beginning on
July 28, 1997 and ending on July 27, 2002, they may include shares in any
Company registration of shares of Common Stock under the Securities Act, other
than a registration relating solely to employee benefit plans or a
registration on a form which does not permit the registration of shares by
selling shareholders, and subject to the ability of the Underwriters to limit
the participation of the Registration Rights Holders due to marketing
concerns. All Registration Rights Holders have waived registration rights with
respect to this offering.     
 
TRANSFER AGENT AND REGISTRAR
   
  The transfer agent and registrar for the Class B Common Stock is ChaseMellon
Shareholder Services ("Chase"). Chase's address is 235 Montgomery Street, 23rd

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of substantial numbers of shares of Class B Common Stock of the
Company in the public market following this offering could adversely affect
the market price of the Class B Common Stock. Upon completion of this
offering, the Company will have outstanding 1,639,762 shares of Class A Common
Stock and 7,156,191 shares of Class B Common Stock. The Class A Common Stock

only be sold in compliance with Rule 144.
 
  The 1,639,762 shares of Class A Common Stock and the remaining 3,756,191

by the Company in private transactions in reliance upon exemptions under the
Securities Act. The Restricted Shares generally may be sold in the public
market only if registered under the Securities Act or sold in compliance with

public market in reliance on Rule 144(k) immediately following the closing of
this offering and an additional 1,002,350 shares of Class A Common Stock and
1,300,920 shares of Class B Common Stock will be eligible for sale in the
public market pursuant to Rule 144 and Rule 701 under the Securities Act

Hill, Inc.; or (ii) a transfer of any or all of such Common Stock either (A)
during his or her lifetime, by bona fide gift, (B) upon his or her death, by
will or intestacy, or (C) to a trust, the beneficiaries of which are
exclusively the transferor or members of his or her immediate family, provided
that such transferee agrees in writing to be bound by the foregoing
restrictions.
 
  Each executive officer, director, current shareholder or optionee, other
than the Selling Shareholders, who will, upon the closing of this offering,
hold an aggregate of 860,000 shares of Class A Common Stock and 1,467,619

  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including persons deemed to be affiliates of the
Company, whose Restricted Shares have been fully paid for and held for at
least a year from the later of the date of the issuance by the Company or
acquisition from an affiliate of the Company, may sell such securities in
brokers' transactions or directly to market makers beginning approximately 90
days after the date of this Prospectus, provided the number of shares sold in
any three-month period does not exceed the greater of 1% of the then

based on the number of shares to be outstanding
 
                                      48

after this offering) or the average weekly trading volume in the public market
during the four calendar weeks preceding the filing of the seller's Form 144.
Sales under Rule 144 are also subject to certain notice of sale requirements
and availability of current public information concerning the Company. After
two years have elapsed from the later of the issuance of Restricted Shares by
the Company or their acquisition from an affiliate of the Company, such shares
may be sold without limitation, pursuant to Rule 144(k), by persons who have
not been affiliates of the Company for at least three months. Rule 144 also
provides that affiliates who are selling shares that are not Restricted Shares
must nonetheless comply with the same restrictions applicable to Restricted
Shares with the exception of the holding period requirement.
 
  Restricted Shares that have been issued in reliance on Rule 701 (such as
shares of Class B Common Stock issued under the Plan) may be resold by persons
other than affiliates of the Company, beginning approximately 90 days after
the date of this Prospectus, subject only to the manner of sale provisions of
Rule 144, and may be resold by affiliates of the Company under Rule 144
without compliance with its one-year holding period requirement.
 
  Rule 144A under the Securities Act would permit, subject to certain
conditions, the sale by the current holders of Restricted Shares of all or a
portion of their shares to certain "qualified institutional buyers," as
defined in Rule 144A.
 
  Certain shareholders of the Company hold registration rights. See
"Description of Capital Stock - Registration Rights." If such holders exercise
their demand registration rights and cause a large number of shares to be
registered and sold in the public market, such sales may have a material
adverse effect on the market price of the Class B Common Stock. If the Company
is required in a Company-initiated registration to register the shares held by
such holders pursuant to the exercise of their piggyback registration rights,
such sales may have a material adverse effect on the Company's ability to
raise needed capital.
   
  At September 30, 1997, the Company had outstanding options to purchase
20,000 shares of Class A Common Stock and 1,713,075 shares of Class B Common
Stock, of which 20,000 shares of Class A Common Stock and 177,498 of Class B
Common Stock were exercisable. After the completion of this offering, the
Company intends to file a Form S-8 registration statement under the Securities
Act to register all shares of Class B Common Stock issuable under the Plan and
the Purchase Plan. The S-8 registration statement will become effective
immediately upon filing. Shares of Class B Common Stock issued pursuant to the
S-8 registration statement will be eligible for resale in the public market,
subject to the Rule 144 limitations applicable to affiliates of the Company.
    
  Prior to this offering there has been no public market for the Class B
Common Stock of the Company and no prediction can be made as to the effect, if
any, that market sales of shares or the availability of shares for sale will
have on the market price of the Class B Common Stock prevailing from time to
time. Sales of substantial numbers of shares of Class B Common Stock in the
public market could adversely affect the market price of the Class B Common
Stock and could impair the Company's ability to raise capital through a sale
of its equity securities.

  Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all shares offered hereby, if
any are taken.
 
  The Underwriters propose to offer the shares of Class B Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus, and in part to certain securities dealers at
such price less a concession not in excess of $   per share. The Underwriters
may allow, and such dealers may reallow, a concession not in excess of $   per
share to certain brokers and dealers. After the shares of Class B Common Stock
are released for sale to the public, the offering price and other selling
terms may from time to time be varied by the Representatives.
 
  The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of 510,000
additional shares of Class B Common Stock to cover over-allotments, if any. If
the Underwriters exercise their over-allotment option, the Underwriters have
severally agreed, subject to certain conditions, to purchase approximately the
same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the 3,400,000 shares of Class
B Common Stock offered hereby. The Underwriters may exercise such option only
to cover over-allotments in connection with the sale of the 3,400,000 shares
of Class B Common Stock offered hereby.
 
  The Company, all of the executive officers and directors of the Company, all
of the holders of Common Stock and certain of the option holders have agreed,
subject to certain exceptions, not to offer, sell, contract to sell or
otherwise dispose of any shares of Common Stock for a period of 180 days after
the date of this Prospectus without the prior written consent of Adams,
Harkness & Hill, Inc. All Selling Shareholders have agreed, subject to certain
exceptions, not to offer, sell, contract to sell or otherwise dispose of any
shares of Common Stock for a period of 365 days after the date of this
Prospectus without the prior written consent of Adams, Harkness & Hill, Inc.
 
  The Representatives of the Underwriters have advised the Company that the
Underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.

  In order to facilitate the offering of the Class B Common Stock, the
Underwriters may engage in transactions that stabilize, maintain or otherwise
affect the price of the Class B Common Stock. Specifically, the Underwriters
may over-allot the Class B Common Stock in connection with this offering,
creating a short position in the Class B Common Stock for their own account.
In addition, to cover over-allotments or to stabilize the price of the Class B
Common Stock, the Underwriters may bid for, and purchase, shares of the Class
B Common Stock in the open market. The Underwriters may also reclaim selling
concessions allowed to an underwriter or a dealer for distributing Class B
Common Stock in this offering, if the Underwriters repurchase previously
distributed the Class B Common Stock in transactions to cover their short
positions, in stabilization transactions or otherwise. Finally, the
Underwriters may bid for, and purchase, shares of the Class B Common Stock in
market making transactions and impose penalty bids. These activities may
stabilize or maintain the market price of the Class B Common Stock above the
market level that may otherwise prevail. The Underwriters are not required to
engage in these activities, and may terminate any such activities at any time.
 
  Prior to this offering, there has been no public market for the Class B
Common Stock. The initial public offering price will be negotiated among the
Company and the Representatives. Among the factors to be considered in
determining the initial public offering price of the Common Stock, in addition
to prevailing market conditions, will be the Company's historical performance,
estimates of the business potential and earnings prospects of the Company, an
assessment of the Company's management and the consideration of the above
factors in relation to market valuation of companies in related businesses.
 
  The Class B Common Stock has been approved for listing, subject to official
notice of issuance, on the Nasdaq National Market under the symbol "TIER."
 
  The Company and the Selling Shareholders have agreed to indemnify the
several Underwriters against, or contribute to losses arising out of, certain
liabilities, including liabilities under the Securities Act.
   
  In July 1997, the Company issued 420,953 shares of Series A Preferred Stock,
resulting in aggregate proceeds of approximately $2.2 million. Certain
employees of Adams, Harkness & Hill, Inc., one of the Representatives,
purchased an aggregate of 38,574 shares of the Company's Series A Preferred
Stock for an aggregate purchase price of approximately $203,000, which upon
the closing of this offering, will convert into 38,574 shares of the Company's
Class B Common Stock. For services as placement agent in connection with the
Series A Preferred Stock financing, Adams, Harkness & Hill, Inc. received
approximately $100,000 (approximately $68,000 net of certain expenses). In
August 1997, AH&H Partners Fund Limited Partnership, a related party to Adams,
Harkness & Hill, Inc., purchased 95,238 shares of the Company's Class B Common
Stock from certain of the Company's shareholders for an aggregate purchase
price of approximately $500,000. See "Certain Transactions."

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
Tier Technologies, Inc.
 
  We have audited the accompanying consolidated balance sheets of Tier
Technologies, Inc. as of December 31, 1996 and September 30, 1997, and the
related consolidated statements of income, shareholders' equity, and cash
flows for the years ended December 31, 1995 and 1996 and for the nine month
period ended September 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Tier Technologies, Inc. at
December 31, 1996 and September 30, 1997, and the results of its operations
and its cash flows for the years ended December 31, 1995 and 1996 and for the
nine month period ended September 30, 1997 in conformity with generally
accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 The Company
 
  Tier Technologies, Inc. (the "Company") provides information technology
consulting, application development and software engineering services to large
companies and government entities.
   
  The Company was formerly owned by Tier Group (a partnership) and its
partners. In November 1995, the partners of Tier Group transferred all of the
assets of the partnership to the Company and simultaneously dissolved the
partnership. In conjunction with this dissolution, certain partners assumed
the outstanding liabilities of Tier Group and other partners contributed
additional capital in the form of notes payable to the Company. As a result of
the transaction, the shares owned by Tier Group were retired and the partners
of Tier Group retained identical ownership and voting percentages. The
transferred assets and liabilities of Tier Group were recorded at historical
cost.     
 
 Basis of Presentation
 
  The accompanying financial statements include the accounts of the Company
and its wholly owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated. The Company translates the accounts of its
foreign subsidiaries using the local foreign currency as the functional
currency. The assets and liabilities of the foreign subsidiaries are
translated into U.S. dollars using exchange rates in effect at the balance
sheet date, revenues and expenses are translated using the average exchange
rate for the period, and gains and losses from this translation process are
credited or charged to shareholders' equity. Foreign currency transaction
gains and losses have not been material.
 
  In September 1997, the Company changed its fiscal year end to September 30.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported results of operations during the reporting period.
Actual results could differ from those estimates.
 
 Interim Financial Information
 
  The interim financial statements for the nine months ending September 30,
1996 are unaudited but have been prepared on the same basis as the audited
financial statements and include all adjustments, consisting only of normal
recurring adjustments, that the Company considers necessary for a fair
presentation of its results of operations and cash flows for this period.
Operating results for the nine months ended September 30, 1996 and 1997 are
not necessarily indicative of the results that may be expected for any future
periods.
 
 Revenue Recognition
   
  The majority of the Company's revenues are from time and material contracts
and are recognized as services are performed. Revenues from fixed price
contracts are recognized using the percentage-of-completion method of contract
accounting based on the ratio of incurred costs to total estimated costs.
Losses on contracts are recognized when they become known. Actual results of
contracts may differ from management's estimates and such differences could be
material. Most of the Company's contracts are terminable by the client
following limited notice and without significant penalty to the client. The
completion, cancellation or significant reduction in the scope of a large
project could have a material adverse effect on the Company's business,
financial condition and results of operations. Unbilled receivables were $0
and $676,021 at December 31, 1996 and September 30, 1997, respectively.
Unbilled receivable for one client accounted for 11% of total accounts
receivables at September 30, 1997.

  REVENUE RECOGNITION - (CONTINUED)
 
  Revenues derived from sales to governmental agencies were $799,211,
$2,709,706 and $10,133,147 for the years ended December 31, 1995 and 1996 and
the nine month period ending September 30, 1997, respectively.
   
 Credit Evaluations and Significant Clients     
   
  The Company extends credit based on an evaluation of its client's financial
condition and does not require collateral. The Company's historical credit
losses have not been significant.     
   
  During the nine months ending September 30, 1997, sales to three clients
totaled $5,019,140, $4,734,373 and $4,436,656, which represented 22%, 21% and
20% of total revenues, respectively. Accounts receivable balances at September
30, 1997 relating to these three clients amounted to $1,610,627. During 1996,
sales to two clients totaled $9,471,534 and $2,338,730, which represented 59%
and 15% of total revenues, respectively. Accounts receivable balances at
December 31, 1996 relating to these two clients amounted to $1,727,702. During
1995, sales to one client totaled $8,423,946, which represented approximately
68% of total revenues.     
 
 Equipment and Improvements
   
  Equipment and improvements are stated at cost. Depreciation and amortization
are computed using the straight-line method over the shorter of the estimated
useful life of the asset or the lease term, which range from three to five
years.     
 
 Long-Lived Assets
 
  The Company records impairment losses on long-lived assets used in
operations, such as equipment and improvements, and intangible assets when
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by those assets are less than the carrying amount of the
assets.
 
 Deferred Financing Costs
 
  Deferred financing costs represent costs incurred in connection with this
proposed initial public offering of the Company's Class B common stock. This
amount will be recorded as a reduction of shareholders' equity upon the
successful completion of the initial public offering of Class B common stock.
 
 Stock-Based Compensation
 
  The Company accounts for employee stock options in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB 25") and in the year ended December 31, 1996 adopted the
disclosure-only alternative described in Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" ("FAS 123").
 
 Income Taxes
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 "Accounting for Income Taxes," ("FAS
109"), which requires the use of the liability method in accounting for income
taxes. Under this method, deferred income tax assets and liabilities are
determined based on differences between financial reporting and tax bases of
assets and liabilities and are measured using enacted tax rules and laws that
are expected to be in effect when the differences are expected to reverse.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)
 
 Net Income Per Share
 
  Except as noted below, net income per share is computed using the weighted
average number of common shares outstanding. Common equivalent shares from
stock options (using the treasury stock method) have been included in the
computation only when dilutive. Pursuant to applicable Securities and Exchange
Commission ("SEC") Staff Accounting Bulletins, common and common equivalent
shares (stock options and preferred stock) issued during the period commencing
12 months prior to the initial filing of a proposed public offering at prices
below the assumed public offering price have been included in the calculation
as if they were outstanding for all periods presented (using the treasury
stock method for stock options and warrants and the as-if-converted method for
preferred stock at the estimated initial public offering price).
 
 Pro Forma Shareholders' Equity (unaudited)
 
  The Company's pro forma shareholders' equity as of September 30, 1997 gives
effect to the automatic conversion of all preferred stock outstanding into an
aggregate of 420,953 shares of Class B common stock, effective upon the
closing of the Company's initial public offering.
 
 Reclassifications
 
  Certain reclassifications have been made to the prior years' financial
statements to conform to the current year presentation.
 
 Impact of Recently Issued Accounting Standards
 
  In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings per Share" ("FAS 128"), which is required to be adopted in
fiscal year 1998. At that time the Company will be required to change the
method currently used to compute earnings per share and to restate earnings
per share for all prior periods.
 
  Under the new requirements for calculating basic (primary) earnings per
share, the dilutive effect of common stock equivalents will be excluded.
Diluted earnings per share will include the dilutive effect of common stock
equivalents. The impact of FAS 128 will not be significant to the calculation
of primary or fully diluted earnings per share.
 
  In June 1997, the Financial Accounting Standards Board issued Statement No.
130 "Reporting Comprehensive Income," ("FAS 130"), and Statement No. 131
"Disclosure about Segments of an Enterprise and Related Information" ("FAS
131"). The Company is required to adopt these Statements in fiscal year 1999.
FAS 130 establishes new standards for reporting and displaying comprehensive
income and its components. FAS 131 requires disclosure of certain information
regarding operating segments, products and services, geographic areas of
operation and major customers. Adoption of these Statements is expected to
have no impact on the Company's consolidated financial position, results of
operations or cash flows.

  The Company has a credit agreement with a bank which provides for lines of
credit of up to $2,250,000 for general corporate purposes and $1,500,000 for
acquisition purposes (including up to $500,000 for stand-by letters of

1997, the outstanding borrowings were $555,532 and $2,417,813, respectively.
Interest payments are due monthly. At May 31, 1998 all outstanding principal
and remaining interest borrowed under the $2,250,000 line of credit becomes
due and payable. At December 31, 1997 all outstanding principal and remaining
interest borrowed under the $1,500,000 line of credit will convert into a term
loan to be repaid over four years.     
 
  The Company also has an equipment line of credit agreement with the same
bank. Under the agreement, the Company may borrow up to $399,500 through May
31, 1998 at variable interest rates of 1.75% above the bank's prime rate. At

7. SHAREHOLDERS' EQUITY
 
 Common Stock
 
  In February 1997, the Company's Board of Directors authorized two classes of
common stock, Class A common stock (2,400,000 shares authorized) and Class B
common stock (12,600,000 shares authorized). Each then outstanding share of
common stock was converted into 40 shares of Class A common stock and 60
shares of Class B common stock. All share and per share information in the
accompanying financial statements has been retroactively adjusted to reflect
this conversion.
   
  The holders of Class A and Class B common stock have 10 votes and 1 vote,
respectively. Each Class A common stock will convert into one share of Class B
common stock upon transfer, except in limited circumstances. Upon conversion
of shares of Class A common stock into shares of Class B common stock, such
Class A common stock shares are retired from the authorized shares and are not
reissuable by the Company. As a result of such conversions, the number of
authorized shares of Class A common stock is 2,304,762 at September 30, 1997.
    
 Convertible Preferred Stock
 
  In July 1997, the Company issued 420,953 shares of Series A preferred stock
at $5.25 per share resulting in net proceeds of approximately $1.9 million.
Each holder of Series A preferred stock may convert such holder's preferred
stock to shares of Class B common stock. The Series A preferred stock has the
same voting rights as the Class B common stock. Series A preferred stock is
initially convertible into one share of the Class B common stock, subject to
certain antidilution provisions. Additionally, Series A preferred stock is
automatically converted upon the earlier of the completion of an underwritten
public offering of common stock or as of June 30, 2003.

stock are entitled to receive an amount of $5.25 per share prior and in
preference to any distribution of the Company assets to holders of Class A and
Class B common stock.

  For the year ended December 31, 1996, the Company issued options to purchase
440,000 shares of Class A common stock and 660,000 shares of Class B common
stock. The options were issued to two officers of the Company at exercise
prices ranging from $0.12 to $1.82 per share. Options for 200,000 shares of
Class A common stock and 300,000 shares of Class B common stock vested upon
grant. The remaining options vest ratably over a three year period, except
that 33.3% of the options vest upon completion of this offering. The Company
has the right of first refusal under certain limited circumstances to
repurchase any unvested common stock purchased under these options for a five
year period from the date of grant at the respective exercise price. These
same two officers were granted options in February 1997 to purchase an
additional 240,000 shares of Class A common stock at an exercise price of
$3.58 per share. As of September 30, 1997, options for 660,000 shares of Class
A and 660,000 shares of Class B common stock had been exercised at prices
ranging from $0.12 to $3.58 per share (weighted average exercise price of
$1.66 per share) and options for 20,000 shares of Class A common stock at an
exercise price of $3.58 per share remain outstanding. These outstanding
options will expire in 2002. The weighted average fair value of options
granted to these two employees during the year ended December 31, 1996 and the
nine months ended September 30, 1997 were $0.18 and $0.48 per share,
respectively. At September 30, 1997 820,000 shares of nonvested stock issued
pursuant to exercises were subject to repurchase.     
       
 1996 Equity Incentive Plan
 
  In February 1997, the Company adopted the Plan, under which the Board of
Directors may issue Class B incentive stock options to employees and
nonstatutory stock options, stock bonuses or the right to purchase restricted
stock to employees, consultants and outside directors. Upon the adoption of
the Plan, the Company reserved 1,250,000 shares of Class B common stock for
issuance under the Plan, of which 100,000 shares are reserved for outside
directors. The Board of Directors determines who shall receive awards, the
number of shares and the exercise price (which cannot be less than the fair
market value at date of grant for incentive stock options and other awards, or
85% of the fair market value for nonstatutory stock options). Options granted
under the Plan expire no more than 10 years from the date of grant and must
vest at a rate of at least 20% per year over 5 years from date of grant. The
Company has the right of first refusal with respect to common stock purchased
under these options for a five year period from the date of purchase and also
has the right to repurchase shares of Class B common stock acquired under the
Plan within ninety days of the termination of the participant's employment at
a repurchase price equal to the greater of the fair market value of the common
stock on the date of termination or the exercise price. Such right of first
refusal and repurchase right expire upon an initial public offering. In July
1997, the Plan was amended to increase the number of shares authorized for
issuance under the Plan to 1,811,714.

  At September 30, 1997, options to acquire 207,498 Class B common shares had
vested and no shares of nonvested stock issued pursuant to exercises of
options were subject to repurchase. The weighted average fair value of options
granted to employees under the Plan during the nine-month period ended
September 30, 1997 was $0.85 per share. At September 30, 1997 options to
purchase 68,639 shares of Class B common stock were available for grant. The
weighted average remaining life of outstanding options under the Plan at
September 30, 1997 is 9.00 years.     
 
 Pro Forma Disclosures of the Effect of Stock-Based Compensation
 
  The Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under FAS 123 requires the use
of option valuation models that were not developed for use in valuing employee
stock options. Under APB 25, because the exercise price of the Company's
employee stock options has equaled or exceeded the market price of the
underlying common stock on the grant date, no compensation expense has been
recorded.
 
 Pro forma Disclosures of the Effect of Stock Based Compensation - (continued)
 
  Pro forma information regarding net income and net income per share is
required by FAS 123, which also requires that the information be determined as
if the Company has accounted for its employee stock options granted subsequent
to December 31, 1994 under the fair value method of FAS 123. Under this
method, the estimated fair value of the options is amortized to expense over
the options' vesting period. The effect of applying FAS 123 fair value method
to the Company's stock-based awards results in net income and net income per
share are as follows:

7. SHAREHOLDERS' EQUITY - (CONTINUED)     
 
  The fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions:
 
<TABLE>   
<CAPTION>
                                                                    NINE MONTH

                                                      ------------ -------------
     <S>                                              <C>          <C>
     Expected dividend yield.........................         0%            0%

     Risk-free interest rate.........................      5.78%         6.48%
     Expected life of the option.....................  1-4 years     1-5 years
</TABLE>    
 
  The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions, including the expected stock price volatility.
Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in
the subjective input assumptions can materially affect the fair value
estimates, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock
options.
 
  Because FAS 123 is applicable only to options granted subsequent to December
31, 1994, its adjusted effect will not be fully reflected until 1999.
 
8. ACQUISITIONS
 
  On December 16, 1996, the Company acquired certain assets and liabilities of

11. INCOME TAXES - (CONTINUED)     
 
  Effective January 1, 1996, the Company changed from the cash to the accrual
method of accounting for income tax purposes. Differences in income tax basis
existing at that date are being amortized to taxable income over a four year
period.
 
  Significant components of the provision for income taxes are as follows:

  Prior to December 31, 1994, earnings of the Company accrued to Tier Group
for income tax purposes through consulting and management agreements. Any U.S.
federal and state income taxes on the earnings of the partnership were payable
by the partners and, accordingly, no provision for U.S. federal or state
income taxes was made for those years, with the exception of minimum state
franchise taxes. Effective January 1, 1995, the Company terminated its
consulting and management agreements with Tier Group. In connection with the
dissolution of Tier Group and the transfer of all of its assets and
liabilities, the Company recorded deferred income taxes related to temporary
differences associated with the transfer of assets and liabilities. The
recording of such deferred income taxes resulted in a charge to the provision
for income taxes of approximately $165,000 in the year ended December 31,
1995.
 
12. RETIREMENT PLAN
 
  The Company maintains a savings plan under Section 401(k) of the Internal
Revenue Code (the "401(k) Plan"). Under the 401(k) Plan, participating
employees may defer a portion of their pretax earnings up to the Internal
Revenue Service annual contribution limit. The Company's contributions to the
401(k) Plan are discretionary. The Company has not contributed any amounts to
the 401(k) Plan to date.

13. SUBSEQUENT EVENTS
 
 Proposed Public Offering of Common Stock
 
  On October 1, 1997, the Board of Directors authorized the Company to proceed
with an initial public offering of the Company's Class B common stock. If the
offering is consummated under the terms presently anticipated, all of the
outstanding shares of convertible preferred stock at September 30, 1997 will
automatically convert into shares of Class A common stock. In addition, the
Board of Directors authorized an increase in the number of authorized Class B
common shares to 42,600,000, subject to shareholder approval.
 
 1996 Equity Incentive Plan
 
  On October 1, 1997, the Board of Directors increased the authorized shares
of Class B Common Stock for issuance under the Plan to 2,989,333, subject to
shareholder approval, to be effective upon the Company's initial public
offering of Class B common stock.
 
 Employee Stock Purchase Plan
 
  On October 1, 1997, the Company's Employee Stock Purchase Plan was adopted
by the Board of Directors, subject to shareholder approval, to be effective
upon the completion of the Company's initial public offering of its common
stock. The Company has reserved a total of 100,000 shares of Class B common
stock for issuance under the plan. Eligible employees may purchase common
stock at 85% of the lesser of the fair market value of the Company's Class B
common stock on the first day or the last day of the applicable purchase
period.
 
 Voting Trust
 
  All of the current Class A shareholders (the "Beneficiaries") have
transferred their Class A common stock into a voting trust. The Company's
Chief Executive Officer and President are the trustees of the voting trust
(the "Trustees") and have the exclusive right to vote all shares of Class A
common stock held in the voting trust. The voting trust has a term of 10 years
and is renewable by consent of the Beneficiaries and the Trustees during the
last 2 years of the original or an extended term. The voting trust terminates
upon the earlier of the expiration of the term or in the event of (i) an
agreement of the Trustees to terminate or (ii) the death of the sole remaining
Trustee, leaving no incumbent or identified successor.
   
14.  LINE OF CREDIT     
   
  In November 1997, the Company entered into a credit agreement which provides
for a revolving line of credit of up to $4,500,000 for general corporate
purposes and an equipment line of up to $500,000 which will periodically
convert to term loans, and simultaneously paid off all outstanding borrowings
under the bank line of credit discussed in Note 4. The new credit agreement
matures in December 1998. Borrowings under the revolving line are limited to
the lesser of $4,500,000 or 80% of eligible accounts receivable and are
secured by the Company's assets. Borrowings under the equipment line are
limited to the lesser of $500,000 or 80% of the cost of the equipment
purchased. The revolving line and equipment line bear interest at the bank's
prime rate plus 1.50% and 1.75% per annum, respectively. Certain executive
officers have personally guaranteed these lines of credit. The guarantees
terminate upon the completion of this offering if the Company achieves certain
debt to tangible net worth ratios. The lines of credit require the Company to
maintain certain minimum financial ratios.

1. ACCOUNTING POLICIES
 
 Organization and Basis of Presentation
 
  Encore Consulting, Inc. ("Encore") was established on April 15, 1996 to
provide custom software development and information technology consulting
services. During the period from April 15, 1996 (inception) through December
31, 1996, all of Encore's revenues were derived from a contract with the State
of Missouri. Encore does not require collateral for receivables and invoices
are generally due within 45 days.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Cash Equivalents
 
  Encore considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
 Income Taxes
 
  The shareholders have elected under Subchapter S of the Internal Revenue
Code to include Encore's taxable income in their personal income tax returns
for federal and state income tax purposes. Accordingly, Encore was not subject
to federal and state income taxes during the period presented.
 
 Revenue Recognition
 
  Encore revenues are from time and materials contracts, which are recognized
as services are performed.
 
2. PRO FORMA STATEMENT OF INCOME DATA (UNAUDITED)
 
  The accompanying statement of income for the period from April 15, 1996
through December 31, 1996 includes an unaudited pro forma adjustment for
income taxes which would have been recorded if the Company had not been an S
corporation, based on the tax laws in effect during the period.
 
  The pro forma income tax provision consists of the following for the period
from April 15, 1996 through December 31, 1996:

</TABLE>
 
3. BANK LINE OF CREDIT
 
  Encore has a credit agreement with a bank which provided for a revolving
line of credit of up to $850,000 through September 1, 1997. Borrowings under
the line of credit bore interest payable quarterly at the bank's prime rate
plus 1.5% (9.75% at December 31, 1996). Borrowings are secured by
substantially all of Encore's assets. Borrowings are guaranteed by the
shareholders of Encore. At December 31, 1996, outstanding borrowings under the
line of credit were $440,713.
 
4. LEASE COMMITMENT
 
  Encore leases its principal facilities under an operating lease which
expires in October 1997. The lease may be renewed for up to two successive
terms of one year each at Encore's option, subject to 2% annual rent
increases. Future minimum lease payments for this noncancellable lease for the
year ending December 31, 1997 total $7,917. Rent expense for the period from
April 15, 1996 (inception) through December 31, 1996 was $1,583.
 
5. SUBSEQUENT EVENT
 
  Effective December 31, 1996, Encore entered into an asset sale agreement
under which it sold substantially all of its net assets and assigned its
rights to its contract with the State of Missouri to Tier Technologies, Inc.
The financial statements do not include any adjustments to the recorded
amounts of assets and liabilities which may result from this transaction.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
Albanycrest Limited
 
  We have audited the accompanying balance sheet of Albanycrest Limited as of
June 30, 1997 and the related statements of income, shareholders' equity and
cash flows for the period from inception (November 13, 1996) to June 30, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements
based on our audit.
 
  We conducted our audit in accordance with United Kingdom auditing standards
which do not differ in any significant respect from United States generally
accepted auditing standards. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Albanycrest Limited at
June 30, 1997 and the results of its operations and its cash flows for the
period from inception (November 13, 1996) to June 30, 1997 in conformity with
United States generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1 BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
 Organization and Basis of Presentation
 
  Albanycrest Limited ("Albanycrest") provides information technology ("IT')
consulting, conforming applications development and systems integration
services.
 
  Albanycrest was incorporated in November 1996 under the laws of England and
Wales as a private limited company.
 
  On July 11, 1997, the shareholders and directors of Albanycrest entered into
an agreement with Tier Technologies, Inc., a California corporation, for the
sale of Albanycrest's business. The accompanying financial statements do not
reflect any adjustments arising from this agreement.
 
  The accompanying financial statements have been prepared in accordance with
United States generally accepted accounting principles ("US GAAP').
 
  These financial statements do not comprise statutory accounts of Albanycrest
within the meaning of section 240 of the Companies Act 1985, as amended, of
Great Britain. Albanycrest has not prepared any such accounts.
 
 Concentrations
 
  Sales to one customer accounted for 100% of Albanycrest's revenue from the
date of inception to June 30, 1997. The loss of this customer would have a
material adverse effect on Albanycrest's business, financial condition and
results of operations.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with US GAAP requires
management to make estimates and assumptions that affect the amounts reported
in the financial statements and accompanying notes. Actual results could
differ from those estimates.
 
 Revenue Recognition
 
  Revenue is derived from time and material contracts and recognized during
the period in which the services are provided.
 
 Income Taxes
 
  Income taxes are computed using the liability method, in accordance with
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes." Under this method, deferred income tax assets and liabilities are
determined based on temporary differences between the financial reporting and
tax bases of assets and liabilities and are measured using enacted tax rates
and laws.
 
 
2 ACCRUED AND OTHER LIABILITIES
 
  Accrued and other liabilities consist of the following:

  NOTES TO THE SELECTED UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL
                                  INFORMATION
   
  Pro forma and offering adjustments for statement of operations for the nine
months ended September 30, 1997 are as follows:     
 
    (1) The Albanycrest condensed statement of operations is presented after
  translation using the local currency as the functional currency.
 
    (2) Reflects the amortization of intangible assets acquired in the
  Albanycrest acquisition recorded at $565,628 amortized over a six year
  period.
 
    (3) Net income per share is computed using the weighted average number of
  shares of common stock outstanding plus common equivalent shares from
  convertible preferred stock, that will be converted upon the closing of the
  Company's proposed initial public offering (using the if-converted method).
  Pursuant to the Securities and Exchange Commission Staff Accounting
  Bulletins, common and common equivalent shares issued by the Company at
  proceeds below the assumed public offering price for the twelve-month
  period prior to the offering have been included in the computation as if
  they were outstanding for all periods presented (using the treasury stock
  method at the estimated initial public offering price).
 
  See Note 8 of the Tier Technologies, Inc. Consolidated Financial Statements
regarding contingent payments related to the Albanycrest acquisition.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article IV of the Registrant's Amended and Restated Articles of
Incorporation (see Exhibit 3.1) provides for the indemnification of the
officers and directors of the Registrant to the fullest extent permissible
under California law. In addition, Article IX, Section 1 of the Registrant's
Amended and Restated Bylaws (see Exhibit 3.2) requires that the Registrant
indemnify, and, in certain instances, advance expenses to, its agents, with
respect to certain costs, expenses, judgments, fines, settlements and other
amounts incurred in connection with any proceeding, to the full extent
permitted by applicable law. Pursuant to its Articles and Bylaws, the
Registrant has entered into indemnification agreements with each of its
officers and directors, the form of which is filed as Exhibit 10.24.
 
  Section 317(b) of the California Corporations Code (the "Corporations Code")
provides that a corporation may indemnify any person who was or is a party or
is threatened to be made a party to any "proceeding" (as defined in Section
317(a) of the Corporations Code), other than an action by or in the right of
the corporation to procure a judgment in its favor, by reason of the fact that
such person is or was a director, officer, employee or other agent of the
corporation (collectively, an "Agent"), against expenses, judgments, fines,
settlements and other amounts actually and reasonably incurred in connection
with such proceeding if the Agent acted in good faith and in a manner the
Agent reasonably believed to be in the best interest of the corporation and,
in the case of a criminal proceeding, had no reasonable cause to believe the
conduct was unlawful.
 
  Section 317(c) of the Corporations Code provides that a corporation shall
have power to indemnify any Agent who was or is a party or is threatened to be
made a party to any threatened, pending or completed action by or in the right
of the corporation to procure a judgment in its favor by reason of the fact
that such person is or was an Agent, against expenses actually and reasonably
incurred by the Agent in connection with the defense or settlement of such
action if the Agent acted in good faith and in a manner such Agent believed to
be in the best interest of the corporation and its shareholders.
 
                                     II-1
<PAGE>
 
  Section 317(c) further provides that no indemnification may be made
thereunder for any of the following: (i) in respect of any claim, issue or
matter as to which the Agent shall have been adjudged to be liable to the
corporation, unless and only to the extent that the court in which such
proceeding is or was pending shall determine that such Agent is fairly and
reasonably entitled to indemnity for expenses, (ii) of amounts paid in
settling or otherwise disposing of a pending action without court approval and
(iii) of expenses incurred in defending a pending action which is settled or
otherwise disposed of without court approval.
 
  Section 317(d) of the Corporations Code requires that an Agent be
indemnified against expenses actually and reasonably incurred to the extent
the Agent has been successful on the merits in the defense of proceedings
referred to in subdivisions (b) or (c) of Section 317.
 
  Except as provided in Section 317(d), and pursuant to Section 317(e),
indemnification under Section 317 shall be made by the corporation only if
specifically authorized and upon a determination that indemnification is
proper in the circumstances because the Agent has met the applicable standard
of conduct set forth in Section 317(b) or (c), by any of the following: (i) a
majority vote of a quorum consisting of directors who are not parties to the
proceeding, (ii) if such a quorum of directors is not obtainable, by
independent legal counsel in a written opinion, (iii) approval of the
shareholders, provided that any shares owned by the Agent may not vote
thereon, or (iv) the court in which such proceeding is or was pending.
 
  Pursuant to Section 317(f) of the Corporations Code, the corporation may
advance expenses incurred in defending any proceeding upon receipt of an
undertaking by the Agent to repay such amount if it is ultimately determined
that the Agent is not entitled to be indemnified.
 
  Section 317(h) provides, with certain exceptions, that no indemnification
shall be made under Section 317 where it appears that it would be inconsistent
with a provision of the corporation's articles, bylaws, a shareholder
resolution or an agreement which prohibits or otherwise limits
indemnification, or where it would be inconsistent with any condition
expressly imposed by a court in approving a settlement.
 
  Section 317(i) authorizes a corporation to purchase and maintain insurance
on behalf of an Agent for liabilities arising by reason of the Agent's status,
whether or not the corporation would have the power to indemnify the Agent
against such liability under the provisions of Section 317.
 
  Section 10 of the Underwriting Agreement between the Underwriters, the
Registrant and the Selling Shareholders (see Exhibit 1.1), provides that the
Underwriters shall indemnify and hold harmless the Selling Shareholders, the
Registrant from and against any liability caused by any materially misleading
or untrue statement or omission in the Registration Statement or Prospectus
furnished to the Registrant by the Underwriters for use therein.
 
  In addition, Article IX, Section 1 of the Bylaws of the Registrant
authorizes the Registrant to purchase and maintain insurance on behalf of any
person indemnified by the Company. The Registrant currently maintains a
directors and officers liability insurance policy in the amount of $3,000,000.

ITEM 17. UNDERTAKINGS.
 
  (a) The undersigned registrant hereby undertakes to provide to the
underwriters at the closing specified in the underwriting agreement
certificates in such denominations and registered in such names as required by
the underwriters to permit prompt delivery to each purchaser.
 
  (b) 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 hereunder, 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.
 
  (c) The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, 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 Securities 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 Securities Act
  of 1933, 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.

with your representatives and those of the Company, and while they have not
independently verified and are not passing upon and do not assume the
responsibility for, the accuracy, fairness or completeness of the statements
contained in the Registration Statement or the Prospectus, nothing has come to
such counsel's attention which gives them reason to believe that, as of its
effective date, the Registration Statement or any further amendment thereto made
by the Company prior to such Time of Delivery (other than the financial
statements, including the notes and schedules thereto, or any other financial or
accounting information as set forth or referred to therein, as to which such
counsel need express no opinion) contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading or that, as of its date,
the Prospectus or any further amendment or supplement thereto made by the
Company prior to such Time of Delivery (other than the financial statements,

information as set forth or referred to therein, as to which such counsel need
express no opinion) contained an untrue statement of a material fact or omitted
to state a material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading or that, as of such
Time of Delivery, either the Registration Statement or the Prospectus or any
further amendment or supplement thereto made by the Company prior to such Time
of Delivery (other than the financial statements, including the notes and
schedules thereto, or any other financial or accounting information as set forth
or referred to therein, as to which such counsel need express no opinion)
contains an untrue statement of a material fact or omits to state a material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading; and they do not know of any
amendment to the Registration Statement required to be filed which is not filed
as required.

effective under the Act.  To the best of such counsel's knowledge, no stop order
suspending the effectiveness of the Registration Statement has been issued by
the Commission nor has any proceeding been instituted or contemplated for that
purpose under the Act.  The Prospectus has been filed with the Commission
pursuant to Rule 424(b) of the Rules and Regulations under the Act within the
time period required thereby.

to state securities or Blue Sky laws or as to compliance with the antifraud
provisions of federal and state securities laws);

Shares (as to which such counsel need express no opinion) and such as have been
obtained or made under the Act or the rules and regulations thereunder;

          (II)   Immediately prior to the date hereof, based solely on the
examination of the Company's stock record books and a certificate from each

Shareholder in accordance with its terms, except insofar as indemnification
provisions may be limited by applicable law and except as enforceability may be

relating to or affecting creditors' rights generally or by general equitable
principles and limitations on the availability of equitable remedies.

Statement and the effective date of the most recently filed post-effective
amendment to the Registration Statement and also at each Time of Delivery, Ernst
& Young LLP shall have furnished to you a letter or letters, dated the

10.  INDEMNIFICATION AND CONTRIBUTION.

     (A)  The Company will indemnify and hold harmless each Underwriter and each
person, if any, who controls such Underwriter against any losses, claims,
damages or liabilities, joint or several, to which such Underwriter or
controlling person may become subject, under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or the
omission or alleged omission to state in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement thereto
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they were made, not
misleading, and will reimburse each Underwriter for any legal or other expenses
reasonably incurred by such Underwriter in connection with investigating or
defending any such action or claim as such expenses are incurred; provided,
however, that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in any Preliminary Prospectus, the Registration Statement or the Prospectus
or any such amendment or supplement in reliance upon and in conformity with
written information furnished to the Company by any Underwriter through you
expressly for use therein.

     (B)  Each Selling Shareholder, severally and not jointly, will indemnify
and hold harmless each Underwriter and each person, if any, who controls such
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter or controlling person may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i) a
breach of such Selling Shareholder's representations and

                                      23.
<PAGE>
 
warranties contained in Section 2, (ii) an untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or (iii) the omission or alleged omission to state in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or any amendment or
supplement thereto a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances in which they were
made, not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in any Preliminary Prospectus, the Registration Statement or
the Prospectus, or any amendment or supplement thereto in reliance upon and in
conformity with written information furnished to the Company by such Selling
Stockholder expressly for use therein, and will reimburse each Underwriter for
any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim as such
expenses are incurred; and, provided further, that the liability of the Selling
Shareholders under the indemnity agreement in this Section 10 shall not exceed
the total initial public offering price of the Shares sold by the Selling
Shareholders under this Agreement, less underwriters' discounts.

     (C)  Each Underwriter will indemnify and hold harmless the Company and the
Selling Shareholders against any losses, claims, damages or liabilities to which
the Company or the Selling Shareholders may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in any Preliminary Prospectus, the Registration Statement or the Prospectus
or any such amendment or supplement in reliance upon and in conformity with
written information furnished to the Company by such Underwriter through you
expressly for use therein; and will reimburse the Company and the Selling
Shareholders for any legal or other expenses reasonably incurred by the Company
or the Selling Shareholders in connection with investigating or defending any
such action or claim as such expenses are incurred.

     (D)  Promptly after receipt by an indemnified party under subsection (a),
(b) or (c) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection to the

                                      24.
<PAGE>
 
extent prejudiced by failure to notify. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of any indemnified party. No indemnifying party shall be liable for
the settlement of any action or claim affected without its written consent.

     (E)  If the indemnification provided for in this Section 10 is unavailable
to or insufficient to hold harmless an indemnified party under subsection (a),
(b) or (c) above in respect of any losses, claims, damages or liabilities (or
actions in respect thereof) referred to therein, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Shareholders on the one hand and the
Underwriters on the other from the offering of the Shares.  If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (d) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Selling Shareholders on the one hand and the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations.  The relative
benefits received by the Company and the Selling Shareholders on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses) received
by the Company and the Selling Shareholders, respectively, bear to the total
underwriting discounts and

                                      25.
<PAGE>
 
commissions received by the Underwriters, in each case as set forth in the table
on the cover page of the Prospectus. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Selling Shareholders on
the one hand or the Underwriters on the other and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company, the Selling Shareholders and the
Underwriters agree that it would not be just and equitable if contributions
pursuant to this subsection (e) were determined by pro rata allocation (even if
the Underwriters were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to above in this subsection (e). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this subsection (e) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this subsection (e), no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Shares underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No Selling Stockholder
shall be liable for contribution under this Section 10 in circumstances where
such Selling Stockholder would not be required to provide indemnification if
indemnification were available. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (e) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

     (F)  The obligations of the Company and the Selling Shareholders under this
Section 10 shall be in addition to any liability which the Company and the
Selling Shareholders may otherwise have and shall extend, upon the same terms
and conditions, to each person, if any, who controls any Underwriter within the
meaning of the Act; and the obligations of the Underwriter under this Section 10
shall be in addition to any liability which the respective Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company and to each person, if any, who controls the
Company or any Selling Shareholder within the meaning of the Act.

11.  TERMINATION.

     (A)  If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your

                                      26.
<PAGE>
 
discretion arrange for you or another party or other parties to purchase such
Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such Shares,
then the Company and the Selling Shareholders shall be entitled to a further
period of thirty-six hours within which to procure another party or other
parties satisfactory to you to purchase such Shares on such terms. In the event
that, within the respective prescribed periods, you notify the Company that you
have so arranged for the purchase of such Shares, or the Company and the Selling
Shareholders notify you that they have so arranged for the purchase of such
Shares, you or the Company and the Selling Shareholders shall have the right to
postpone such Time of Delivery for a period of not more than seven days, in
order to effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees to file promptly any amendments to the
Registration Statement or the Prospectus which in your opinion may thereby be
made necessary. The term "Underwriter" as used in this Agreement shall include
any person substituted under this Section with like effect as if such person had
originally been a party to this Agreement with respect to such Shares.

     (B)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased does not exceed one-eleventh of the aggregate number of all
the Shares to be purchased at such Time of Delivery, then the Company and the
Selling Shareholders shall have the right to require each non-defaulting
Underwriter to purchase the number of Shares which such Underwriter agreed to
purchase hereunder at such Time of Delivery and, in addition, to require each
non-defaulting Underwriter to purchase its pro rata share (based on the number
of Shares which such Underwriter agreed to purchase hereunder) of the Shares of
such defaulting Underwriter or Underwriters for which such arrangements have not
been made; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

     (C)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased exceeds one-eleventh of the aggregate number of all the
Shares to be purchased at such Time of Delivery, or if the Company and the
Selling Shareholders shall not exercise the right described in subsection (b)
above to require non-defaulting Underwriters to purchase Shares of a defaulting
Underwriter or Underwriters, then this Agreement (or, with respect to the Second
Time of Delivery, the obligations of the Underwriters to purchase and of the
Company to sell the Optional Shares) shall thereupon terminate, without
liability on the part of any non-defaulting Underwriter or the Company or the
Selling Shareholders, except for the expenses to be borne by the Company and the
Selling Shareholders and the Underwriters as provided in Section 8 hereof and
the indemnity and

                                      27.
<PAGE>
 
contribution agreements in Section 10 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

12.  SURVIVAL.  The respective indemnities, agreements, representations,
warranties and other statements of the Company and the several Underwriters, as
set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of any Underwriter or any controlling person of any Underwriter, or the
Company, or any officer or director or controlling person of the Company and
shall survive delivery of and payment for the Shares.

13.  EXPENSES OF TERMINATION.  If this Agreement shall be terminated pursuant to
Section 11 hereof, the Company or the Selling Shareholders shall not then be
under any liability to any Underwriter except as provided in Section 8 and
Section 10 hereof; but, if for any other reason this Agreement is terminated,
the Company will reimburse the Underwriters through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Underwriters in making preparations for the
purchase, sale and delivery of the Shares not so delivered, but the Company and
the Selling Shareholders shall then be under no further liability to any
Underwriter in respect of the Shares not so delivered except as provided in
Section 8 and Section 10 hereof.

14.  NOTICE.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Adams, Harkness & Hill, Inc. on behalf of you as the
Representatives; and in all dealing with any Selling Shareholders hereunder, you
and the Company shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of such Selling Shareholders made or given by any
or all of the Attorneys-in-Fact for such Selling Shareholders.

     All statements, requests, notices and agreements hereunder shall be in

or sent by mail, telex or facsimile transmission to such Underwriter at its
address set forth in its Underwriter's Questionnaire or telex constituting such
Questionnaire, which address will be supplied to

the Company by you on request. Any such statements, requests, notices or
agreements shall take effect upon receipt thereof.

15.  MISCELLANEOUS.

Company and each person who controls the Company and the Selling Shareholders or
any Underwriter, and their respective heirs, executors, administrators,
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement.  No purchaser of any of the Shares from
any Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

original, but all such counterparts shall together constitute one and the same
instrument.

                                    ANNEX I


     Pursuant to Section 9(f) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

     (i)    They are independent certified public accountants with respect to
the Company and its subsidiaries within the meaning of the Act and the
applicable published rules and regulations thereunder;

     (ii)   In their opinion, the consolidated financial statements and any
supplementary financial information and schedules (and, if applicable,
prospective financial statements and/or pro forma financial information)
examined by them and included in the Prospectus or the Registration Statement
comply as to form in all material respects with the applicable accounting
requirements of the Act and the related published rules and regulations
thereunder; and, if applicable, they have made a review in accordance with
standards established by the American Institute of Certified Public Accountants
of the unaudited consolidated interim financial statements, selected
consolidated financial data, pro forma financial information, prospective
financial statements and/or condensed financial statements derived from audited
consolidated financial statements of the Company for the periods specified in
such letter, as indicated in their reports thereon, copies of which have been
furnished to the representatives of the Underwriters (the "Representatives");

     (iii)  The unaudited selected financial information with respect to the
consolidated results of operations and financial position of the Company for the
five most recent fiscal years included in the Prospectus agrees with the
corresponding amounts (after restatements where applicable) in the audited
consolidated financial statements for such five fiscal years;

     (iv)   On the basis of limited procedures, not constituting an examination
in accordance with generally accepted auditing standards, consisting of a
reading of the unaudited consolidated financial statements and other information
referred to below, a reading of the latest available interim consolidated
financial statements of the Company and its subsidiaries, inspection of the
minute books of the Company and its subsidiaries since the date of the latest
audited consolidated financial statements included in the Prospectus, inquiries
of officials of the Company and its subsidiaries responsible for financial and
accounting matters and such other inquiries and procedures as may be specified
in such letter, nothing came to their attention that caused them to believed
that:

     (A)    the unaudited consolidated statements of income, consolidated
balance sheets and consolidated statements of cash flows included in the
Prospectus do not

                                      33.
<PAGE>
 
comply as to form in all material respects with the applicable accounting
requirements of the Act and the related published rules and regulations
thereunder, or are not in conformity with generally accepted accounting
principles applied on a basis substantially consistent with the basis for the
audited consolidated statements of income, consolidated balance sheets and
consolidated statements of cash flows included in the Prospectus;

     (B)  any other unaudited consolidated income statement data and
consolidated balance sheet items included in the Prospectus do not agree with
the corresponding items in the unaudited consolidated financial statements from
which such data and items were derived, and any such unaudited data and items
were not determined on a basis substantially consistent with the basis for the
corresponding amounts in the audited consolidated financial statements included
in the Prospectus;

     (C)  the unaudited consolidated financial statements which were not
included in the Prospectus but from which were derived any unaudited condensed
consolidated financial statements referred to in Clause (A) and any unaudited
consolidated income statement data and consolidated balance sheet items included
in the Prospectus and referred to in Clause (B) were not determined on a basis
substantially consistent with the basis for the audited consolidated financial
statements included in the Prospectus;

     (D)  any unaudited pro forma consolidated condensed financial statements
included in the Prospectus do not comply as to form in all material respects
with the applicable accounting requirements of the Act and the published rules
and regulations thereunder or the pro forma adjustments have not been properly
applied to the historical amounts in the compilation of those statements;

                                      OF

                            TIER TECHNOLOGIES, INC.


     James L. Bildner and George K. Ross do hereby certify that:

                    Chief Financial Officer, respectively, of TIER TECHNOLOGIES,
                    INC., a California corporation (the "Corporation").

     SECOND:        The Articles of Incorporation of this corporation are
                    amended and restated in full to read as follows:

                                   ARTICLE I

     The name of the Corporation is TIER TECHNOLOGIES, INC.

                                  ARTICLE II

     The purpose of the Corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business, or the
practice of a profession permitted to be incorporated by the California
Corporations Code.

                                  ARTICLE III

     A.   AUTHORIZED CAPITALIZATION. The Corporation is authorized to issue
three classes of shares designated "Class A Common Stock," "Class B Common
Stock" and "Preferred Stock," respectively. The total number of shares of all
classes of stock that the Corporation shall have authority to issue is forty-
nine million, nine hundred four thousand, seven hundred sixty-two (49,904,762)
shares. The number of shares of Class A Common Stock that the Corporation is
authorized to issue is two million, three hundred four thousand, seven hundred
sixty-two (2,304,762) shares. The number of shares of Class B Common Stock that
the Corporation is authorized to issue is forty-two million, six hundred
thousand (42,600,000) shares. The number of shares of Preferred Stock that the
Corporation is authorized to issue is five million (5,000,000) shares.

     B.   PREFERRED STOCK.

          1.   The Preferred Stock may be issued from time to time in one or
more series. Except as otherwise provided in this Article III, the Board of
Directors is hereby
<PAGE>
 
authorized to determine and alter the rights, preferences, privileges and
restrictions granted to or imposed upon any wholly unissued series of Preferred
Stock, and to fix the number of shares of any such series of Preferred Stock,
and the designation of any such series of Preferred Stock. The Board of
Directors, within the limits and restrictions stated in this Article III or any
resolution of the Board of Directors originally fixing the number of shares
constituting any series, may increase or decrease (but not below the number of
shares of such series then outstanding) the number of any series subsequent to
the issuance of shares of that series.

          2.   RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS OF THE SERIES A
CONVERTIBLE PREFERRED STOCK.

               (A)  Four Hundred Twenty Thousand Nine Hundred and Fifty Three
(420,953) shares of Preferred Stock are designated Series A Convertible
Preferred Stock (the "Series A Preferred") with the rights, preferences and
privileges specified herein.

               (B)  (I)  Dividend Provisions. Subject to the rights of series of
                         -------------------  
preferred stock which may from time to time come into existence, the holders of
shares of the Series A Preferred shall be entitled to receive dividends on the
Series A Preferred, when, as and if declared by the Board of Directors, out of
any assets legally available therefor, in proportion to the number of shares of
Series A Preferred which is held by each such holder. Such dividends shall not
be cumulative.

                    (II) Liquidation Preference. Upon the dissolution,
                         ----------------------    
liquidation or winding-up of the Corporation and upon the completion of any
other distribution that may be required with respect to series of preferred
stock that may from time to time come into existence, if assets remain in the
Corporation, the holders of the Series A Preferred shall be entitled to receive,
prior and in preference to any distribution of any of the assets of the
Corporation to the holders of common stock by reason of their ownership thereof,
an amount equal to $5.25 for each outstanding share of Series A Preferred. If
upon the occurrence of such event, the assets and funds thus distributed among
the holders of the Series A Preferred shall be insufficient to permit the
payment to such holders of the full aforesaid preferential amounts, then,
subject to the rights of series of preferred stock that may from time to time
come into existence, the entire assets and funds of the Corporation legally
available for distribution shall be distributed ratably among the holders of the
Series A Preferred in proportion to the amount of such stock owned by each such
holder.

               (C)  Class A Common Stock and Class B Common Stock.  Upon the
                    ---------------------------------------------           
completion of the distribution to the holders of Series A Preferred required by
subparagraph (b)(ii) of this Section 2 and any other distribution that may be
required with respect to series of preferred stock that may from time to time
come into existence, if assets remain in the Corporation, the holders of the
Class A Common Stock and the Class B Common Stock (collectively, the "Common
Stock") shall be entitled to share all of the remaining assets of the
Corporation ratably.

               (D)  (I)  Conversion.  Each share of Series A Preferred shall be
                         ----------                                            
convertible, at the option of the holder thereof, at any time after the date of
issuance of such 

                                       2
<PAGE>
 
share, at the office of the Corporation or any transfer agent for the Series A
Preferred, into such number of fully paid and non-assessable shares of Class B
Common Stock as is determined by dividing $4.75 by the Conversion Price
applicable to such share, determined as hereinafter provided, in effect on the
date the certificate is surrendered for conversion. The price at which shares of
Class B Common Stock shall be deliverable upon conversion of such shares of
Series A Preferred (the "Conversion Price") shall initially be $4.75 per share
of Class B Common Stock. Such initial Conversion Price shall be adjusted as
hereinafter provided.

                    (II)  Automatic Conversion. Each share of Series A Preferred
                         --------------------     
shall be automatically converted into such number of fully paid and non-
assessable shares of Class B Common Stock as is determined by dividing $4.75 by
the then-effective Conversion Price applicable to such share: (i) on June 30,
2003; or (ii) immediately upon the closing of the sale of any class of the
Corporation's common stock in a firm commitment, underwritten public offering
registered under the Securities Act of 1933, as amended (the "Act").

                    (III) Fractional Shares. No fractional shares of Class B
                          -----------------   
Common Stock shall be issued upon conversion of shares of Series A Preferred. In
lieu of any fractional shares to which the holder would otherwise be entitled,
the Corporation shall pay cash equal to such fraction multiplied by the then
effective Conversion Price.

                    (IV)  Mechanics of Conversion.
                          ----------------------- 

                         (A)  In order for a holder of shares of Series A
Preferred to convert any such shares into shares of Class B Common Stock, such
holder shall surrender the certificate or certificates for such shares of Series
A Preferred, at the office of the transfer agent for the Series A Preferred (or
at the principal office of the Corporation if the Corporation serves as its own
transfer agent), together with written notice that such holder elects to convert
all or any number of shares of Series A Preferred represented by such
certificate or certificates. Such notice shall state such holder's name or the
names of the nominees in which such holder wishes the certificate or
certificates for shares of Class B Common Stock to be issued. If required by the
Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by a written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or his
or its attorney duly authorized in writing. The date of receipt of such
certificates and notice by the transfer agent (or by the Corporation if the
Corporation serves as its own transfer agent) shall be the conversion date
("Conversion Date"). The Corporation shall, as soon as practicable after the
Conversion Date, issue and deliver at such office to such holder of shares of
Series A Preferred, or to his or its nominees, a certificate or certificates for
the number of shares of Class B Common Stock to which such holder shall be
entitled, together with cash in lieu of any fraction of a share.

                         (B)  The Corporation shall at all times when shares of
Series A Preferred shall be outstanding, reserve and keep available out of its
authorized but unissued shares, for the purpose of effecting the conversion of
all of the shares of Series A Preferred, such number of its duly authorized
shares of Class B Common Stock as shall from time to time be sufficient to
effect the conversion of all outstanding shares of Series A Preferred.

                                       3
<PAGE>
 
                         (C)  Upon any such conversion, no adjustment to the
Conversion Price shall be made for any declared but unpaid dividends on the
shares of Series A Preferred surrendered for conversion or on the shares of
Class B Common Stock delivered upon conversion.

                         (D)  All shares of Series A Preferred which shall have
been surrendered for conversion as provided by subparagraph (d)(i) in this
Section 2 or which are converted automatically as provided by subparagraph
(d)(ii) of this Section 2, shall no longer be deemed to be outstanding and all
rights with respect to such shares, including the rights, if any, to receive
notices and to vote, shall immediately cease and terminate on the Conversion
Date, except only the right of the holders thereof to receive shares of Class B
Common Stock in exchange therefor and payment of any dividends declared but
unpaid thereon. Any shares of Series A Preferred so converted shall be retired
and canceled and shall not be reissued, and the Corporation (without the need
for shareholder action) may from time to time take such appropriate action as
may be necessary to reduce the authorized shares of Series A Preferred
accordingly.

                         (E)  The Corporation shall pay any and all issue and
other taxes that may be payable in respect of any issuance or delivery of shares
of Class B Common Stock upon conversion of shares of Series A Preferred pursuant
to this Section 2. The Corporation shall not, however, be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and
delivery of shares of Class B Common Stock in a name other than that in which
the shares of Series A Preferred so converted were registered, and no such
issuance or delivery shall be made unless and until the person or entity
requesting such issuance has paid to the Corporation the amount of any such tax
or has established, to the satisfaction of the Corporation, that such tax has
been paid.

                         (F)  (1)  Adjustments to Conversion Price for Certain
                                   -------------------------------------------
Diluting Issues: For purposes of this Subsection (d)(iv)(F) of this Section 2,

                                   (I)   "Options" shall mean rights, options or

or Convertible Securities, excluding options described in subsection

                                   (III) "Convertible Securities" shall mean any
                                          ----------------------

                                   (IV)  "Additional Common Shares" shall mean
                                          ------------------------     
all shares of Common Stock issued (or, pursuant to Subsection (d)(iv)(F)(3) of
this Section 2, deemed to be issued) by the Corporation after the Original Issue
Date, other than:

                                         (AA)  shares of Common Stock issued or
issuable as a dividend or distribution on shares of Series A Preferred;

                                         (BB)  shares of Common Stock issued or
issuable upon conversion of Series A Preferred;

                                         (CC)  options or shares of Common Stock
that may be issued from time to time to employees or directors of, or
consultants to, the Corporation or its subsidiaries pursuant to options granted
under one or more stock option plans or stock purchase plans or agreements
approved by the Board of Directors of the Corporation; subject in the case of
Messrs. James L. Bildner and William G. Barton to an aggregate limit of 750,000
shares of Common Stock of the Corporation (net of any repurchases of shares or
cancellations or expirations of options) so granted during the period beginning
on the Original Issue Date and ending on the closing of a firm-commitment
underwritten public offering of the Corporation's common stock registered under
the Act, and as adjusted for all subdivisions and combinations;

                                         (DD)  options, convertible securities
or shares of Common Stock that may be issued from time to time in connection
with acquisitions of stock or assets or other business combinations;

                                         (EE)  shares of Common Stock for which
adjustment of the Conversion Price is made pursuant to Subsections (d)(iv)(G),
(H) and (I)(2) of this Section 2; and

                                         (FF)  shares of Common Stock issuable
upon exercise of options which are outstanding on the Original Issue Date.

                              (2)  No Adjustment of Conversion Price.
                                   ---------------------------------  
Notwithstanding anything in this Section 2 to the contrary, no adjustment in the
number of shares of Class B Common Stock into which the shares of Series A
Preferred are convertible shall be made, by adjustment in the Conversion Price
thereof: (a) unless the consideration per share (determined pursuant to
Subsection (d)(iv)(F)(V) of this Section 2) for an Additional Common Share
issued or deemed to be issued by the Corporation is less than the Conversion
Price in effect on the date of, and immediately prior to, the issuance of such
Additional Common Shares, or (b) if prior to such issuance, the Corporation
receives written notice from the holders of at least a majority of the then
outstanding shares of Series A Preferred agreeing that no such adjustment shall
be made as the result of the issuance of Additional Common Shares.

                              (3)  (I)  Deemed Issue of Additional Common
Shares. If the Corporation at any time or from time to time after the Original
Issue Date shall issue any Options or Convertible Securities, then the maximum
number of shares of

                                       5
<PAGE>
 
Common Stock (as set forth in the instrument relating thereto without regard to
any provision contained therein designed to protect against dilution) issuable
upon the exercise of such Options or, in the case of Convertible Securities and
Options therefor, the conversion or exchange of such Convertible Securities,
shall be deemed to be Additional Common Shares issued as of the time of such
issue, provided that Additional Common Shares shall not be deemed to have been
issued unless the consideration per share (determined pursuant to Subsection
(d)(iv)(F)(v) of this Section 2 hereof) of such Additional Common Shares would
be less than the Conversion Price in effect on the date of and immediately prior
to such issue, as the case may be, and provided further that in any such case in
which Additional Common Shares are deemed to be issued: (II) No further
adjustment in the Conversion Price shall be made upon the subsequent issue of
Convertible Securities or shares of Common Stock issued upon the exercise of
such Options or conversion or exchange of such Convertible Securities;

                                   (II)  No further adjustment in the Conversion
Price shall be made upon the subsequent issue of Convertible Securities or
shares of Common Stock issued upon the exercise of such Options or conversion or
exchange of such Convertible Securities;

                                   (III) If such Options or Convertible
Securities by their terms provide, with the passage of time or otherwise, for
any increase or decrease in the consideration payable to the Corporation, or
decrease or increase in the number of shares of Common Stock issuable upon the
exercise, conversion or exchange thereof, the Conversion Price computed upon the
original issue thereof, and any subsequent adjustments based thereon, shall,
upon any such increase or decrease becoming effective, be recomputed to reflect
such increase or decrease insofar as it affects such Options or the rights of
conversion or exchange under such Convertible Securities (provided, however,
that no such adjustment of the Conversion Price shall effect an adjustment of
the Class B Common Stock previously issued upon conversion of the Series A
Preferred);

                                   (IV)  Upon the expiration or termination of
any unexercised Option or Convertible Security, the Conversion Price computed
upon the original issue thereof shall be readjusted to reflect such expiration
or termination; and

                                   (V)   No readjustment pursuant to
subparagraphs III or IV above shall have the effect of increasing the Conversion
Price to an amount which exceeds the lower of (i) the Conversion Price on the
original adjustment date, or (ii) the Conversion Price that would have resulted
from any issuances of Additional Common Shares between the original adjustment
date and such readjustment date.

                              (4)  Adjustment of Conversion Price Upon Issuance
                                   --------------------------------------------
of Additional Common Shares. In the event the Corporation, at any time after the
- ---------------------------
Original Issue Date, shall issue Additional Common Shares (including Additional
Common Shares deemed to be issued pursuant to Subsection (d)(iv)(F)(3) of this
Section 2), without consideration or for a consideration per share less than the
Conversion Price in effect on the date of and immediately prior to such issue,
then and in such event, such Conversion Price shall be reduced, concurrently
with such issue, to a price (calculated to the nearest cent) determined by
multiplying such Conversion Price by a fraction, (A) the numerator of which
shall be the number of shares of Common Stock outstanding immediately prior to
such issue plus the number of

                                       6
<PAGE>
 
shares of Common Stock which the aggregate consideration received or to be
received by the Corporation for the total number of Additional Common Shares so
issued would purchase at such Conversion Price in effect immediately prior to
such issuance; and (B) the denominator of which shall be the number of shares of
Common Stock outstanding immediately prior to such issue plus the number of
Additional Common Shares so issued. For the purposes of the above calculation,
the number of shares of Common Stock outstanding immediately prior to such issue
shall be calculated on a fully diluted basis, as if all shares of Series A
Preferred and all Convertible Securities had been fully converted into shares of
Common Stock immediately prior to such issuance and any outstanding options or
other rights for the purchase of shares of stock or convertible securities had
been fully exercised immediately prior to such issuance (and the resulting
securities fully converted into shares of Common Stock, if so convertible) as of
such date, but not including in such calculation any additional shares of Common
Stock issuable with respect to shares of Series A Preferred, Convertible
Securities, or outstanding options, warrants or other rights for the purchase of
shares of stock or convertible securities, solely as a result of the adjustment
of the respective Conversion Prices (or other conversion ratios) resulting from
the issuance of the Additional Common Shares causing the adjustment in question.

                              
                              (5)  Determination of Consideration. For purposes
                                   ------------------------------
of this Subsection (d)(iv)(F)(5) of this Section 2, the consideration received
by the Corporation for the issue of any Additional Common Shares shall be
computed as follows:

                                   (I)  Cash and Property:  Such consideration
                                        -----------------                     
shall:

                                        (AA) insofar as it consists of cash, be
computed at the aggregate of cash received by the Corporation, excluding amounts
paid or payable for accrued interest or accrued dividends;

                                        (BB) insofar as it consists of property
other than cash, be computed at the fair market value thereof at the time of
such issue, as determined in good faith by the Board of Directors; and

                                        (CC) in the event Additional Common
Shares are issued together with other shares or securities or other assets of
the Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (aa) and (bb) above,
as determined in good faith by the Board of Directors.

                                   (II) Options and Convertible Securities. The
                                        ----------------------------------
consideration per share received by the Corporation for Additional Common Shares
deemed to have been issued pursuant to Subsection (d)(iv)(F)(3) of this Section
2, relating to Options and Convertible Securities, shall be determined by
dividing,

                                        (AA) the total amount, if any, received
or receivable by the Corporation as consideration for the issue of such Options
or Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set

                                       7
<PAGE>
 
forth in the instruments relating thereto, without regard to any provision
contained therein designed to protect against dilution) payable to the
Corporation upon the exercise of such Options or the conversion or exchange of
such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                                         (BB) the maximum number of shares of
Common Stock (as set forth in the instruments relating thereto, without regard
to any provision contained therein designed to protect against dilution)
issuable upon the exercise of such Options or the conversion or exchange of such
Convertible Securities.

                                   (III) Multiple Closing Dates. In the event
                                         ----------------------
the Corporation shall issue on more than one date Additional Common Shares which
are comprised of shares of the same series or class of preferred shares, and
such issuance dates occur within a period of no more than 120 days, then the
Conversion Price shall be adjusted only once on account of such issuances, with
such adjustment to occur upon the final such issuance and to give effect to all
such issuances as if they occurred on the date of the final such issuance.

                         (G)  Adjustment for Share Splits and Combinations. If
                              --------------------------------------------
the Corporation at any time or from time to time after the Original Issue Date
shall effect a subdivision of the outstanding shares of Common Stock, the
Conversion Price then in effect immediately before that subdivision shall be
proportionately decreased. If the Corporation shall at any time or from time to
time after the Original Issue Date combine the outstanding shares of Common
Stock, the Conversion Price then in effect immediately before the combination
shall be proportionately increased. Any adjustment under this paragraph shall
become effective at the close of business on the date the subdivision or
combination becomes effective.

                         (H)  Adjustment for Certain Dividends and
                              ------------------------------------
Distributions. In the event the Corporation at any time, or from time to time
- -------------     
after the Original Issue Date shall make or issue, or fix a record date for the
determination of holders of shares of Common Stock entitled to receive, a
dividend or other distribution payable in additional shares of Common Stock,
then and in each such event the Conversion Price then in effect shall be
decreased as of the time of such issuance or, in the event such a record date
shall have been fixed, as of the close of business on such record date, by
multiplying the Conversion Price then in effect by a fraction:

                              (1)  the numerator of which shall be the total
number of shares of Common Stock issued and outstanding immediately prior to the
time of such issuance or the close of business on such record date, and

                              (2)  the denominator of which shall be the total
number of shares of Common Stock issued and outstanding immediately prior to the
time of such issuance or the close of business on such record date plus the
number of shares of Common Stock issuable in payment of such dividend or
distribution; provided, however, if such record date shall have been fixed and
such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Conversion Price shall be recomputed accordingly as of
the

                                       8
<PAGE>
 
close of business on such record date and thereafter the Conversion Price shall
be adjusted pursuant to this paragraph as of the time of actual payment of such
dividends or distributions; and provided further, however, that no such
adjustment shall be made if the holders of shares of Series A Preferred
simultaneously receive a dividend or other distribution of shares of Common
Stock in a number equal to the number of shares of Common Stock as they would
have received if all outstanding shares of Series A Preferred had been converted
into shares of Common Stock on the date of such event.

                         (I)  Adjustments for Other Dividends and Distributions.
                              -------------------------------------------------
In the event the Corporation at any time or from time to time after the Original
Issue Date shall make or issue, or fix a record date for the determination of
holders of shares of Common Stock entitled to receive, a dividend or other
distribution payable in securities of the Corporation other than shares of
Common Stock, then and in each such event provision shall be made so that the
holders of shares of Series A Preferred shall receive upon conversion thereof in
addition to the number of shares of Common Stock receivable thereupon, the
amount of securities of the Corporation that they would have received had the
shares of Series A Preferred been converted into shares of Common Stock on the
date of such event and had they thereafter, during the period from the date of
such event to and including the conversion date, retained such securities
receivable by them as aforesaid during such period, giving application to all
adjustments called for during such period under this paragraph with respect to
the rights of the holders of shares of Series A Preferred; and provided further,
however, that no such adjustment shall be made if the holders of shares of
Series A Preferred simultaneously receive a dividend or other distribution of
such securities in an amount equal to the amount of such securities as they
would have received if all outstanding shares of Series A Preferred had been
converted into shares of Common Stock on the date of such event.

                              (1)  Adjustment for Reclassification, Exchange, or
                                   ---------------------------------------------
Substitution. If the shares of Class B Common Stock issuable upon the conversion
- ------------
of the shares of Series A Preferred shall be changed into the same or a
different number of any class or classes of shares, whether by capital
reorganization, reclassification, or otherwise (other than a subdivision or
combination of shares or stock dividend provided for above), then and in each
such event the holder of each such share of Series A Preferred shall have the
right thereafter to convert such share into the kind and amount of capital stock
and other securities and property receivable upon such reorganization,
reclassification, or other change, by holders of the number of shares of Class B
Common Stock into which each such share of Series A Preferred might have been
converted immediately prior to such reorganization, reclassification, or change,
all subject to further adjustment as provided herein.

                              (2)  Adjustment for Consolidation or Merger. In
                                   --------------------------------------
case of any consolidation or merger of the Corporation with or into another
corporation (except one in which the holders of capital shares of the
Corporation immediately prior to such merger or consolidation continue to hold
at least a majority by voting power of the capital shares of the surviving
corporation) or the sale of all or substantially all of the assets of the
Corporation to another corporation, each share of Series A Preferred shall
thereafter be convertible (or shall be converted into a security which shall be
convertible) into the kind and amount of shares or other

                                       9
<PAGE>
 
securities or property to which a holder of the number of shares of Class B
Common Stock of the Corporation deliverable upon conversion of such shares of
Series A Preferred would have been entitled upon such consolidation, merger or
sale; and, in such case, appropriate adjustment (as determined in good faith by
the Board of Directors) shall be made in the application of the provisions in
this Section 2 set forth with respect to the rights and interest thereafter of
the holders of shares of Series A Preferred, to the end that the provisions set
forth in this Section 2 (including provisions with respect to changes in and
other adjustments of the Conversion Price) shall thereafter be applicable, as
nearly as reasonably may be, in relation to any capital shares or other property
thereafter deliverable upon the conversion of the shares of Series A Preferred.

                         (J)  No Impairment. The Corporation will not, by
                              -------------    
amendment of its Articles of Incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 2 and in the taking of all such action as may
be necessary or appropriate in order to protect the Conversion Rights of the
holders of shares of Series A Preferred against impairment.

                         (K)  Certificate as to Adjustments. Upon the occurrence
                              -----------------------------  
of each adjustment or readjustment of the Conversion Price pursuant to this
Section 2, the Corporation at its expense shall promptly compute such adjustment
or readjustment in accordance with the terms hereof and furnish to each holder
of Series A Preferred a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of Series A Preferred, furnish or cause to be furnished to
such holder a similar certificate setting forth (i) such adjustments and
readjustments, (ii) the Conversion Price then in effect, and (iii) the number of
shares of Class B Common Stock and the amount, if any, of other property which
then would be received upon the conversion of the Series A Preferred.

                         (L)  Notice of Record Date.  In the event:
                              ---------------------                

                              (1)  that the Corporation declares a dividend (or
any other distribution) on its Class B Common Stock payable in shares of Common
Stock or other securities of the Corporation;

                              (2)  that the Corporation subdivides or combines
its outstanding shares of Class B Common Stock;

                              (3)  of any reclassification of the Class B Common
Stock (other than a subdivision or combination of its outstanding Class B Common
Stock or a share dividend or share distribution thereon), or of any
consolidation or merger of the Corporation into or with another corporation, or
of the sale of all or substantially all of the assets of the Corporation; or

                                       10
<PAGE>
 
                              (4)  of the involuntary or voluntary dissolution,
liquidation or winding up of the Corporation; then the Corporation shall cause
to be filed at its principal office or at the office of the transfer agent of
the Series A Preferred, and shall cause to be mailed to the holders of the
Series A Preferred at their last addresses as shown on the records of the
Corporation or such transfer agent, at least ten days prior to the date
specified in (I) below or twenty days before the date specified in (II) below, a
notice stating

                                   (I)  the record date of such dividend,
distribution, subdivision or combination, or, if a record is not to be taken,
the date as of which the holders of Class B Common Stock of record to be
entitled to such dividend, distribution, subdivision or combination are to be
determined, or

                                   (II) the date on which such reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up is expected
to become effective, and the date as of which it is expected that holders of
Class B Common Stock of record shall be entitled to exchange their shares of
Class B Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, dissolution or winding up.

               (E)  Voting Rights.  In addition to possessing any voting rights
                    -------------                                              
provided for by the California Corporations Code, the holders of the Series A
Preferred shall vote as a class with the holders of the Class B Common Stock on
all matters and shall have the same voting rights as the holders of the Class B
Common Stock, based upon the number of shares of Class B Common Stock into which
each holder's shares of Series A Preferred are convertible.

               (F)  Status of Converted Series A Preferred. In the event any
                    --------------------------------------  
shares of Series A Preferred shall be converted pursuant to Section 2 hereof,
the Shares so converted shall be canceled and shall not be reissuable by the
Corporation.

     C.   CLASS A COMMON STOCK. The shares of Class A Common Stock and shares of
Class B Common Stock shall be identical in all respects and shall have equal
rights and privileges, except as set forth in this paragraph C and in paragraph
D of this Article III. Upon dissolution of the Corporation, the Class A Common
Stock and Class B Common Stock are entitled to share ratably in the assets
thereof that may be available for distribution after satisfaction of creditors
and the payment of any liquidation preference of any outstanding shares of
Preferred Stock.

               1.   DIVIDENDS.

               (A)  Subject to the rights of the Series A Preferred set forth in
Section B.2.(b)(i) of this Article III, and subject to the provisions of Section
C.1(b) below with respect to dividends or distributions in shares of Class A
Common Stock or shares of Class B Common Stock: (i) such dividends or
distributions as may be determined from time to time may be declared and paid or
made upon each share of Class A Common Stock out of any source at the time
lawfully available for the payment of dividends, provided that concurrently
identical dividends or distributions are declared and paid or made upon each
share of Class B Common

                                       11
<PAGE>
 
Stock and (ii) such dividends or distributions as may be determined from time to
time may be declared and paid or made upon each share of Class B Common Stock
out of any source at the time lawfully available for the payment of dividends,
provided that concurrently identical dividends or distributions are declared and
paid or made upon each share of Class A Common Stock.

               (B)  No dividend may be declared or paid or made upon any share
of the Corporation in shares of Class A Common Stock. Subject to the rights of
the Series A Preferred set forth in Section B.2.(b)(i) of this Article III: (i)
in the event that a dividend or distribution is declared and paid or made upon
shares of Class A Common Stock in shares of Class B Common Stock, concurrently
an identical dividend or distribution must be declared and paid or made upon
each share of Class B Common Stock in shares of Class B Common Stock and (ii) in
the event that a dividend or distribution is declared and paid or made upon
shares of Class B Common Stock in shares of Class B Common Stock, concurrently
an identical dividend or distribution must be declared and paid or made upon
each share of Class A Common Stock in shares of Class B Common Stock.

          2.   STOCK COMBINATIONS AND SUBDIVISIONS.  The Corporation shall not
effect a combination (reverse stock split) or a subdivision (stock split) of
either the Class A Common Stock or the Class B Common Stock except in compliance
with the following: (i) the Class A Common Stock shall not be combined or
subdivided unless at the same time there is a proportionate combination or
subdivision of the Class B Common Stock, (ii) the Class B Common Stock shall not
be combined or subdivided unless at the same time there is a proportionate
combination or subdivision of the Class A Common Stock and (iii) neither the
Class A Common Stock nor the Class B Common Stock shall be combined or
subdivided unless an amendment to these Amended and Restated Articles of
Incorporation is approved by (in addition to any other approval by holders of
shares of the Corporation which may be required) the holders of shares of Class
B Common Stock as provided in subsection D.3(c) of this Article III.

          3.   VOTING.  Subject to the provisions of subsections B.2(e) and D.3
of this Article III and except as otherwise required by applicable law related
to class voting rights, the holders of Class A Common Stock shall vote together
with the holders of Class B Common Stock as a single class, provided that the
holders of Class A Common Stock shall have ten (10) votes per share and the
holders of Class B Common Stock shall have one (1) vote per share on all matters
that may be submitted to a vote or consent of the shareholders.  Without
limiting the generality of the foregoing:

               (A)  With respect to the election of Directors (whether such
election is by vote at a meeting of shareholders or by written consent of
shareholders), the holders of Class A Common Stock, Class B Common Stock and
Series A Preferred shall be entitled, voting as a single class to elect the
remaining Directors not subject to the priority right of the holders of Class B
Common Stock to elect one or more Directors as set forth in Subsection D.3(a) of
this Article III. Vacancies on the Board of Directors created by (i) the death,
resignation or removal of a Director who was elected by the holders of Class A
Common Stock, Class B Common Stock

                                       12
<PAGE>
 
and Series A Preferred voting as a single class or (ii) by an increase in the
authorized number of Directors if such vacancy is not to be filled by the
holders of Class B Common Stock voting as a separate class in accordance with
Section D.3(a) of this Article III, may be filled by those Directors (acting by
majority vote, though less than a quorum, or by the act of a sole remaining
Director) who were elected by the holders of Class A Common Stock, Class B
Common Stock and Series A Preferred voting as a single class.

               (B)  Except as may otherwise be required by law, any Director
elected by the holders of Class A Common Stock, Class B Common Stock and Series
A Preferred voting as a single class, or who was elected by those Directors who
were elected by the holders of Class A Common Stock, Class B Common Stock and
Series A Preferred Stock voting as a single class to fill a vacancy, may be
removed from office with or without cause by the holders of shares of Class A
Common Stock, Class B Common Stock and Series A Preferred voting as a single
class, provided that, to the extent permitted by applicable law, any such
Director may be removed for cause by the Board of Directors.

          4.   CONVERSION UPON TRANSFER.

               (A)  Each share of Class A Common Stock shall automatically be
converted into one share of Class B Common Stock in the event that the record or
beneficial ownership of such share of Class A Common Stock shall be transferred
in any manner or for any reason, voluntarily or involuntarily, by operation of
law or otherwise, provided, however, that if the beneficial or record ownership
                  ------------------                                           
of such share of Class A Common Stock is transferred (i) by any holder of Class
A Common Stock to a voting trust created for the holders of Class A Common Stock
("Voting Trust"), (ii) from such Voting Trust to the holder that transferred
such share of Class A Common Stock into the Voting Trust, or (iii) by any person
who was the beneficial holder of fifteen percent (15%) or more of the issued and
outstanding shares of Class A Common Stock (and who was also either the record
holder of such shares of Class A Common Stock or the record holder of one or
more voting trust certificates ("Voting Trust Certificates") for such shares of
Class A Common Stock held in the Voting Trust) as of the date of filing of these
Amended and Restated Articles of Incorporation with the California Secretary of
State (the "Filing Date"), regardless of the number of such shares of Class A
Common Stock, if any, held by such person on any subsequent date (each such
person being referred to as a "15% Class A Holder") to any other 15% Class A
Holder, (including, for purposes of this clause (iii), transfers among 15% Class
A Holders which occur by means of a transfer of record or beneficial ownership
of one or more Voting Trust Certificates), then such share of Class A Common
Stock which is transferred as described in clause (i), (ii) or (iii) shall not
be converted into a share of Class B Common Stock, and provided, further, that
                                                   ----------------------     
any share of Class A Common Stock which is transferred as described in clause
(i), (ii) or (iii) shall remain subject to the provisions of this Section C.4 of
Article III.  A pledge of Class A Common Stock as security for an obligation of
a holder of such stock shall not be considered a transfer for purposes of this
paragraph, unless and until beneficial ownership is transferred to the
pledgeholder.  The conversion into Class B Common Stock shall be deemed to have
occurred (whether or not certificates representing such shares are surrendered)
as of the close of business on the date of transfer, and the person or persons
entitled to receive shares of Class B Common Stock issuable upon such conversion
shall 

                                       13
<PAGE>
 
be treated for all purposes as the record holder or holders of such shares of
Class B Common Stock on that date. For purposes of this Section C.4 of
Article III, "beneficial ownership" shall be determined in accordance with Rule
13d-3 promulgated under the Securities Exchange Act of 1934, as amended, as in
effect on the Filing Date.

               (B)  Before any shares of Class B Common Stock shall be delivered
upon conversion, the holder of shares of Class A Common Stock whose shares have
been converted into Class B Common Stock shall deliver the certificate(s)
representing such shares to the Corporation or its duly authorized agent (or if
such certificates have been lost, stolen or destroyed, such holder shall execute
an agreement satisfactory to the Corporation to indemnify the Corporation from
any loss incurred by it in connection with such conversion), specifying the
place where the Common Stock issued in conversion thereof shall be sent. The
endorsement of the certificates shall be in a form satisfactory to the
Corporation or such agent, as the case may be.

               (C)  The Corporation shall, at all times, reserve and keep
available out of the authorized and unissued shares of Class B Common Stock,
solely for the purpose of effecting the conversion of the outstanding Class A
Common Stock, such number of shares of Class B Common Stock as shall from time
to time be sufficient to effect the conversion of all of the outstanding Class A
Common Stock and if, at any time, the number of authorized and unissued shares
of Class B Common Stock shall not be sufficient to effect conversion of the then
outstanding Class A Common Stock, the Corporation shall take such corporate
action as may be necessary to increase the number of authorized and unissued
shares of Class B Common Stock to such number as shall be sufficient for such
purposes.

               (D)  The Corporation shall pay any and all issuance and other
taxes that may be payable in respect of any issuance or delivery of shares of
Class B Common Stock on conversion of Class A Common Stock. The Corporation
shall not, however, be required to pay any tax which may be payable with respect
to the issuance of any Class B Common Stock in a name other than that in which
the Class A Common Stock so converted was registered, and no such issuance or
delivery shall be made unless and until the person requesting such issuance has
paid to the Corporation the amount of any such tax, or has established, to the
satisfaction of the Corporation, that such tax has been paid.

               (E)  All shares of Class B Common Stock which may be issued upon
conversion of the shares of Class A Common Stock will, upon issuance by the
Corporation, be validly issued, fully paid and non-assessable and free from all
taxes, liens and charges with respect to the issuance thereof.

               (F)  All certificates representing shares of Class A Common Stock
surrendered for conversion or otherwise acquired by the Corporation (all such
shares being referred to as "Converted Shares") shall be appropriately canceled
on the books of the Corporation.  Such shares shall not be reissuable by the
Corporation and the authorized number of shares of Class A Common Stock of the
Corporation shall be reduced by such amount.  Within ninety (90) days after each
anniversary of the Filing Date referred to in subsection C.4(a) 

                                       14
<PAGE>
 
of this Article III the Corporation shall file with the California Secretary of
State an amendment (a "Reduction Amendment") to these Amended and Restated
Articles of Incorporation to reflect the reduction in the authorized number of
shares of Class A Common Stock by an amount equal to the number of Converted
Shares which have become Converted Shares since the most recent to occur of the
Filing Date or the date of filing of the immediately prior Reduction Amendment
or other amendment to these Amended and Restated Articles of Incorporation
("Other Amendment") (such shares being referred to as "New Converted Shares"),
provided that, (i) the Corporation shall not be required to file a Reduction
- -------------
Amendment unless the number of New Converted Shares shall equal at least 50,000
(adjusted for any stock dividends, combinations or subdivisions subsequent to
the Filing Date), (ii) if on any occasion the Corporation shall elect to file an
Other Amendment, then it shall include in such Other Amendment provisions to
reflect any reduction in the authorized number of shares of Class A Common Stock
due to such shares having become New Converted Shares since the most recent to
occur of the Filing Date or the date of filing of the immediately prior
Reduction Amendment or Other Amendment, and (iii) if one or more Reduction
Amendments cannot be filed with the California Secretary of State without
obtaining approval of some or all of the shareholders of the Corporation, the
Corporation shall not be required to file such Reduction Amendments, and in that
case it shall follow the procedure indicated in clause (ii) above, and when all
of the authorized shares of Class A Common Stock have been converted or
otherwise reacquired by the Corporation the Class A Common Stock shall be
automatically eliminated and these Amended and Restated Articles of
Incorporation shall be amended to eliminate any statement of rights,
preferences, privileges and restrictions relating solely to the Class A Common
Stock.

     D.   CLASS B COMMON STOCK.

          1.   DIVIDENDS AND DISTRIBUTIONS.  Subject to the provisions of
Sections B.2(b)(i) and C.1 of this Article III, dividends and distributions may
be declared and paid or made upon the Class B Common Stock as may be permitted
by applicable law.

          2.   STOCK COMBINATIONS AND SUBDIVISIONS. Subject to the provisions of
paragraph C.2 of this Article III, the Class B Common Stock may be combined or
subdivided in such manner as may be permitted by applicable law.

          3.   VOTING.  The holders of the Class B Common Stock shall have the
voting rights set forth below in addition to the rights set forth in Section C.3
of this Article III:

               (a)  With respect to the election of the Board of Directors
(whether such election is by vote at a meeting of shareholders or by written
consent of shareholders), the holders of Class B Common Stock, voting as a
separate class, shall be entitled to elect that number of Directors which is the
largest integral number which is less than fifty percent (50%) of the authorized
number of Directors. Such election shall be from a slate of Director nominees
separate from a slate of Director nominees from which holders of Class A Common
Stock, Class B Common Stock and Series A Preferred voting as a single class
shall elect Directors. Vacancies on the Board of Directors created by (i) the
death, resignation or removal of a Director who was elected by the holders of
Class B Common Stock or (ii) by an increase in the authorized

                                       15
<PAGE>
 
number of Directors, if such vacancy is to be filled by the holders of Class B
Common Stock voting as a separate class in accordance with the immediately
preceding sentence, may be filled by those Directors (acting by majority vote,
though less than a quorum, or by the act of a sole remaining Director) who were
elected by the holders of Class B Common Stock.

               (b)  The holders of Class B Common Stock will be entitled to vote
as a separate class on the removal, with or without cause, of any Director
elected by the holders of Class B Common Stock; provided that, to the extent
permitted by applicable law, any such Director may be removed for cause by the
Board of Directors.

               (c)  The Corporation shall not, without the vote or written
consent by the holders of a majority of the then outstanding shares of Class B
Common Stock, voting together as a single class:

                    (i)  increase the total number of authorized shares of Class
A Common Stock; or

                    (ii) amend these Amended and Restated Articles of
Incorporation or the Corporation's Bylaws if such amendment would change any of
the rights, preferences or privileges provided for the benefit of the Class B
Common Stock or would increase the rights, preferences or privileges of the
Class A Common Stock.

               (d)  At any meeting of the Corporation's shareholders at which
directors are elected or at which a vote is taken on the removal of a director
or directors elected by the holders of Class B Common Stock pursuant to
subsection D.3(a) of this Article III, then, in addition to any other quorum
requirement which must be satisfied, the presence, either in person or by proxy,
of the holders of a majority of the then outstanding shares of Class B Common
Stock shall be required to constitute a quorum for such meeting.

     E.   VOTING RIGHTS IF ONLY ONE CLASS OUTSTANDING. Notwithstanding anything
in these Amended and Restated Articles of Incorporation to the contrary, the
holders of Class B Common Stock shall have exclusive voting power on all matters
at any time when no shares of Class A Common Stock or Preferred Stock are issued
and outstanding, the holders of Class A Common Stock shall have exclusive voting
power on all matters at any time when no shares of Class B Common Stock or
Preferred Stock are issued and outstanding, and the holders of Preferred Stock
shall have exclusive voting power on all matters at any time when no shares of
Class A Common Stock or Class B Common Stock are issued and outstanding.

                                  ARTICLE IV

     A.   LIABILITY FOR MONETARY DAMAGES. The liability of the directors of the
Corporation for monetary damages shall be eliminated to the fullest extent

indemnification of agents (as defined in Section 317 of the California
Corporations Code) for breach of duty to the

                                       16
<PAGE>
 
Corporation and its shareholders through bylaw provisions or through agreements
with the agents, or through shareholder resolutions, or otherwise, in excess of
the indemnification otherwise permitted by Section 317 of the Corporations Code,
subject to the limits on such excess indemnification set for in Section 204 of
the Corporations Code.

                                   ARTICLE V

     Effective on the first date when the Corporation has outstanding securities
designated as qualified for trading as a national market system security on the
National Association of Securities Dealers Automated Quotation System (or any
successor national market system) and has at least 800 holders of its equity
securities as of the record date for the Corporation's most recent annual
meeting of shareholders, the ability of shareholders to cumulate votes in the
election of directors shall be automatically eliminated.

     THIRD:  The foregoing Amended and Restated Articles of Incorporation have
been duly approved by the Board of Directors.

     FOURTH: The foregoing Amended and Restated Articles of Incorporation have
been duly approved by the required vote of shareholders in accordance with
Sections 902 and 903 of the California Corporations Code. The total number of
outstanding shares of each class entitled to vote with respect to the Amended
and Restated Articles of Incorporation is 2,284,762 shares of Class A Common
Stock, 3,335,238 shares of Class B Common Stock and 420,953 shares of Preferred
Stock. The number of shares of each class voting in favor of the Amended and
Restated Articles of Incorporation equaled or exceeded the vote required. The
percentage vote required of each class entitled to vote was a majority of the
shares of Class A Common Stock, a majority of the shares of Class B Common
Stock, a majority of the shares of Preferred Stock and a majority of all such
shares voting together as a class.

     SECTION 1.  PRINCIPAL OFFICE.  The principal executive office of the
corporation shall be located at such place as the Board of Directors may from
time to time authorize. If the principal executive office is located outside
this state, and the corporation has one or more business offices in this state,
the board of directors shall fix and designate a principal business office in

     SECTION 2.  OTHER OFFICES.  Additional offices of the corporation shall be
located at such place or places, within or outside the State of California, as
the Board of Directors may from time to time authorize.

                    SHAREHOLDERS' MEETINGS AND VOTING RIGHTS

     SECTION 1.  PLACE OF MEETINGS.  Meetings of shareholders shall be held at
the principal executive office of the corporation, or at any other place, within
or outside the State of California, which may be fixed either by the Board of
Directors or by the written consent of all persons entitled to vote at such
meeting, given either before or after the meeting and filed with the Secretary
of the Corporation.

     SECTION 2.  ANNUAL MEETING.  The annual meeting of the shareholders of the
corporation shall be held on any date and time which may from time to time be
designated by the Board of Directors. At such annual meeting, directors shall be
elected and any other business may be transacted which may properly come before
the meeting.

     SECTION 3.  POSTPONEMENT OF ANNUAL MEETING.  The Board of Directors and the
Chairman of the Board and the President shall each have authority to hold at an
earlier date and/or time, or to postpone to a later date and/or time, the annual

     SECTION 4.  SPECIAL MEETINGS.

          (a)  Special meetings of the shareholders, for any purpose or
purposes, may be called only by the Board of Directors, the Chairman of the
Board, the President, the Chief Executive Officer, or the holders of shares
entitled to cast not less than ten percent (10%) of the voting power at the
meeting. In calculating "voting power" for purposes of these bylaws, special
voting rights set forth in the corporation's Articles of Incorporation, as
amended or restated, shall be taken into account, giving effect to separate
class or series votes as applicable.

          (b)  Upon written request to the Chairman of the Board of Directors,
the President, any vice president or the Secretary of the corporation by any
person or persons (other than the Board of Directors) entitled to call a special

given to the shareholders entitled to vote, that a meeting will be held at a
time requested by the person or persons calling the meeting, such time to be not
less than thirty-five (35) nor more than sixty (60) days after receipt of such
request.  If such notice is not given 

                                       1
<PAGE>
 
within twenty (20) days after receipt of such request, the person or persons
calling the meeting may give notice thereof in the manner provided by law or in
these bylaws. Nothing contained in this Section 4 shall be construed as
limiting, fixing or affecting the time or date when a meeting of shareholders
called by action of the Board of Directors may be held.

     SECTION 5.  NOTICE OF MEETINGS.  Except as otherwise may be required by law
and subject to subsection 4(b) above, written notice of each meeting of
shareholders shall be given to each shareholder entitled to vote at that meeting
(as provided in Section 12 below), by the Secretary, assistant secretary or
other person charged with that duty, not less than ten (10) (or, if sent by
third class mail, thirty (30)) nor more than sixty (60) days before such

which a director has an interest);

               (2)  a proposal to approve a transaction within the provisions of

               (4)  a proposal to approve a transaction within the provisions of
California Corporations Code, Section 1900 (winding up and dissolution);

               (5)  a proposal to approve a plan of distribution within the
provisions of California Corporations Code, Section 2007 (relating to certain
plans providing for distribution not in accordance with the liquidation rights
of preferred shares, if any).

          At a special meeting, notice of which has been given in accordance
with this Section, action may not be taken with respect to business, the general
nature of which has not 

                                       2
<PAGE>
 
been stated in such notice. At an annual meeting, action may be taken with
respect to business stated in the notice of such meeting, given in accordance
with this Section, and, subject to subsection 5(d) above and subsections 5(e)
and 5(f) below, with respect to any other business as may properly come before
the meeting.

          (e)  Only persons who are nominated in accordance with the following
procedures shall be eligible for election as directors of the corporation.
Nominations of persons for election to the Board of Directors may be made at any
annual meeting of shareholders (x) by or at the direction of the Board of
Directors (or any duly authorized committee thereof) or (y) by any shareholder
of the corporation (i) who is a shareholder of record on the date of the giving
of the notice provided for in this subsection 5(e) and on the record date for
the determination of shareholders entitled to vote at such annual meeting and
(ii) who complies with the notice procedures set forth in this subsection 5(e).

          In addition to any other applicable requirements, for a nomination to
be made by a shareholder, such shareholder must have given timely notice thereof
in proper written form to the Secretary of the corporation.

          To be timely, a shareholder's notice to the Secretary must be
delivered to or mailed and received at the principal executive offices of the
corporation not less than sixty (60) days nor more than ninety (90) days prior
to the date of the annual meeting; provided, however, that in the event that
                                   --------  -------                        
less than seventy (70) days' notice or prior public disclosure of the date of
the annual meeting is given or made to shareholders, notice by the shareholder
in order to be timely must be so received not later than the close of business
on the tenth (10th) day following the day on which such notice of the date of
the annual meeting was mailed or such public disclosure of the date of the
annual meeting was made, whichever first occurs.

          To be in proper written form, a shareholder's notice to the Secretary
must set forth (a) as to each person whom the shareholder proposes to nominate
for election as a director (i) the name, age, business address and residence
address of the person, (ii) the principal occupation of employment of the
person, (iii) the class or series and number of shares of capital stock of the
corporation which are owned beneficially or of record by the person and (iv) any
other information relating to the person that would be required to be disclosed
in a proxy statement or other filings required to be made in connection with
solicitations of proxies for election of directors pursuant to Section 14 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules
and regulations promulgated thereunder; and (b) as to the shareholder giving the
notice (i) the name and record address of such shareholder, (ii) the class or
series and number of shares of capital stock of the corporation which are owned
beneficially or of record by such shareholder, (iii) a description of all
arrangements or understandings between such shareholder and each proposed
nominee and any other person or persons (including their names) pursuant to
which the nomination(s) are to be made by such shareholder, (iv) a
representation that such shareholder intends to appear in person or by proxy at
the meeting to nominate the persons named in its notice, (v) if the shareholder
intends to solicit proxies in support of such shareholder's nominee(s), a
representation to that effect, and (vi) any other information relating to such
shareholder that would be required to be disclosed in a proxy 

                                       3
<PAGE>
 
statement or other filings required to be made in connection with solicitations
of proxies for election of directors pursuant to Section 14 of the Exchange Act
and the rules and regulations promulgated thereunder. Such notice must be
accompanied by a written consent of each proposed nominee to being named as a
nominee and to serve as a director if elected.

          Compliance by a shareholder with the notice provisions and other
requirements of this subsection 5(e) shall not create a duty of the corporation
to include the shareholder's nominee(s) in the corporation's proxy statement or
proxy and the corporation shall retain any discretion it has to omit such
nominee(s) from the corporation's proxy statement and proxy.

          No person shall be eligible for election as a director of the
corporation unless nominated in accordance with the procedures set forth in this
subsection 5(e).  If the Chairman of the annual meeting determines that a
nomination was not made in accordance with the foregoing procedures, the
Chairman shall declare to the meeting that the nomination was defective and such
defective nomination shall be disregarded.

          (f)  No business may be transacted at an annual meeting of
shareholders, other than business that is either (x) specified in the notice of
meeting (or any supplement thereto) given by or at the direction of the Board of
Directors (or any duly authorized committee thereof), (y) otherwise properly
brought before the annual meeting by or at the direction of the Board of
Directors (or any duly authorized committee thereof) or (z) otherwise properly
brought before the annual meeting by any shareholder of the corporation (i) who
is a shareholder of record on the date of the giving of the notice provided for
in this Section 5(f) and on the record date for the determination of
shareholders entitled to vote at such annual meeting and (ii) who complies with
the notice procedures set forth in this subsection 5(f).

          In addition to any other applicable requirements, for business to be
properly brought before an annual meeting by a shareholder, such shareholder
must have given timely notice thereof in proper written form to the Secretary of
the Corporation.

          To be timely, a shareholder's notice to the Secretary must be
delivered to or mailed and received at the principal executive offices of the
corporation not less than sixty (60) days nor more than ninety (90) days prior
to the date of the annual meeting; provided, however, that in the event that
                                   --------  -------                        
less than seventy (70) days' notice or prior public disclosure of the date of
the annual meeting is given or made to shareholders, notice by the shareholder
in order to be timely must be so received not later than the close of business
on the tenth (10th) day following the day on which such notice of the date of
the annual meeting was mailed or such public disclosure of the date of the
annual meeting was made, whichever first occurs.

          To be in proper written form, a shareholder's notice to the Secretary
must set forth as to each matter such shareholder proposes to bring before the
annual meeting (i) a brief description of the business desired to be brought
before the annual meeting and the reasons for conducting such business at the
annual meeting, (ii) the name and record address of such shareholder, (iii) the
class or series and number of shares of capital stock of the corporation which
are owned beneficially or of record by such shareholder, (iv) a description of

<PAGE>
 
(including their names) in connection with the proposal of such business by such
shareholder and any material interest of such shareholder in such business, (v)
a representation that such shareholder intends to appear in person or by proxy
at the annual meeting to bring such business before the meeting, and (vi) if the
shareholder intends to solicit proxies in support of such shareholder's
proposal, a representation to that effect.

          No business shall be conducted at the annual meeting of shareholders
except business brought before the annual meeting in accordance with the
procedures set forth in this subsection 5(f), provided, however, that, once
                                              --------  -------            
business has been properly brought before the annual meeting in accordance with
such procedures, nothing in this subsection 5(f) shall be deemed to preclude the
discussion by any shareholder of any such business.  If the Chairman of an
annual meeting determines that business was not properly brought before the
annual meeting in accordance with the foregoing procedures, the Chairman shall
declare to the meeting that the business was not properly brought before the
meeting and such business shall not be transacted.

     SECTION 6.  MANNER OF GIVING NOTICE.  Notice of any meeting of shareholders
shall be given either personally or by first-class mail, or, if the corporation
has outstanding shares held of record by 500 or more persons (determined as
provided in California Corporations Code Section 605) on the record date for
such meeting, notice may be sent by third-class mail, or by telegraphic or other
written communication, addressed to the shareholder at the address of that
shareholder appearing on the books of the corporation or given by the
shareholder to the corporation for the purpose of notice. If no such address
appears on the corporation's books or is given, notice shall be deemed to have
been given if sent to that shareholder by first-class mail or telegraphic or
other written communication to the corporation's principal executive office, or
if published at least once in a newspaper of general circulation in the county
where that office is located. Notice shall be deemed to have been given at the
time when delivered personally or deposited in the mail or sent by telegram or
other means of written communication.

     If any notice addressed to a shareholder at the address of that shareholder
appearing on the books of the corporation is returned to the corporation by the
United States Postal Service marked to indicate that the United States Postal
Service is unable to deliver the notice to the shareholder at that address, all
future notices shall be deemed to have been duly given without further mailing
if they shall be available to the shareholder on written demand by the
shareholder at the principal executive office of the corporation for a period of
one year from the date of the giving of the notice.

     SECTION 7.  QUORUM AND TRANSACTION OF BUSINESS.

          (a)  Where a separate vote by class or series is required with respect
to any matter pursuant to the corporation's Articles of Incorporation, as
amended or restated, the holders of shares entitled to cast a majority of the
votes which would be cast by all shares of such class or series entitled to vote
thereon shall be required in order to constitute a quorum at any meeting of the
shareholders.  With respect to any other matter, the holders of shares entitled
to cast a majority of the votes which could be voted thereon shall constitute a
quorum.  If a quorum is present, the affirmative vote of the majority of the
voting power represented at the meeting on 

                                       5
<PAGE>
 
any matter shall be the act of the shareholders, except as otherwise required by
law or by the Articles of Incorporation, and except as provided in
subsection (b) below.

          (b)  The shareholders present at a duly called or held meeting of the
shareholders at which a quorum is present may continue to do business until
adjournment, notwithstanding the withdrawal of enough shareholders to leave less
than a quorum, provided that any action taken (other than adjournment) is
approved by at least a majority of the voting power required to constitute a
quorum.

          (c)  In the absence of a quorum, no business other than adjournment
may be transacted, except as described in subsection (b) above.

          SECTION 8.  ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS.  Any meeting
of shareholders may be adjourned from time to time, whether or not a quorum is
present, by the affirmative vote of a majority of shares represented at such
meeting either in person or by proxy and entitled to vote at such meeting.

     In the event any meeting is adjourned, it shall not be necessary to give
notice of the time and place of such adjourned meeting pursuant to Sections 5
and 6 above; provided that if any of the following three events occur, such
notice must be given:

          (a)  announcement of the adjourned meeting's time and place is not
made at the meeting at which the adjournment is taken or

          (b)  such meeting is adjourned for more than forty- five (45) days or

          (c)  after the adjournment, a new record date is fixed for the
adjourned meeting.

     At the adjourned meeting, the corporation may transact any business which
might have been transacted at the original meeting.

     SECTION 9.  WAIVER OF NOTICE, CONSENT TO MEETING OR APPROVAL OF MINUTES.

          (a)  Subject to subsection (b) of this Section 9, the transactions of
any meeting of shareholders, however called and noticed, and wherever held,
shall be as valid as though made at a meeting duly held after regular call and
notice, if a quorum is present either in person or by proxy, and if, either
before or after the meeting, each of the persons entitled to vote but not
present in person or by proxy signs a written waiver of notice or a consent to
holding of the meeting or an approval of the minutes thereof.

          (b)  A waiver of notice, consent to the holding of a meeting or
approval of the minutes thereof need not specify the business to be transacted
at, nor the purpose of the meeting; provided that in the case of proposals
described in subsection (d) of Section 5 above, the general nature of such
proposals must be described in any such waiver of notice and such proposals can
only be approved by waiver of notice, not by consent to holding of the meeting
or approval of the minutes.

                                       6
<PAGE>
 
          (c)  All waivers, consents and approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

          (d)  A person's attendance at a meeting shall constitute waiver of
notice of and presence at such meeting, except when such person objects at the
beginning of the meeting to transaction of any business because the meeting is
not lawfully called or convened and except that attendance at a meeting is not a
waiver of any right to object to the consideration of matters which are required
by law or these bylaws to be in such notice (including those matters described
in subsection (d) of Section 5 above), but are not so included if such person
expressly objects to consideration of such matter or matters at any time during
the meeting.

     SECTION 10.  ACTION BY WRITTEN CONSENT WITHOUT A MEETING.  Any action which
may be taken at any meeting of shareholders may be taken without a meeting and
without prior notice if written consents setting forth the action so taken are
signed by the holders of the outstanding shares having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted.

     Directors may not be elected by written consent except by unanimous written
consent of all shares entitled to vote for the election of directors; provided
that any vacancy on the Board of Directors (other than a vacancy created by
removal) which has not been filled by the board of directors may be filled by
the written consent of a majority of the voting power entitled to vote for the
election of directors.

     Any written consent may be revoked pursuant to California Corporations Code
Section 603(c) prior to the time that written consents of the number of shares
required to authorize the proposed action have been filed with the Secretary.
Such revocation must be in writing and will be effective upon its receipt by the
Secretary.

     If the consents of all shareholders entitled to vote have not been
solicited in writing, and if the unanimous written consent of all such
shareholders shall not have been received, the Secretary shall give prompt
notice of any corporate action approved by the shareholders without a meeting to
those shareholders entitled to vote on such matters who have not consented
thereto in writing. This notice shall be given in the manner specified in
Section 6 above. In the case of approval of (i) a transaction within the
provisions of California Corporations Code, Section 310 (relating to certain
transactions in which a director has an interest), (ii) a transaction within the
provisions of California Corporations Code, Section 317 (relating to
indemnification of agents of the corporation), (iii) a transaction within the
provisions of California Corporations Code, Sections 181 and 1201 (relating to
reorganization), and (iv) a plan of distribution within the provisions of
California Corporations Code, Section 2007 (relating to certain plans providing
for distribution not in accordance with the liquidation rights of preferred
shares, if any), the notice shall be given at least ten (10) days before the
consummation of any action authorized by that approval.

     SECTION 11.  VOTING.  Voting at any meeting of shareholders need not be by
ballot; provided, however, that elections for directors must be by ballot if
balloting is demanded by a shareholder at the meeting and before the voting
begins.

                                       7
<PAGE>
 
     Every person entitled to vote at an election for directors may cumulate the
votes to which such person is entitled, i.e., such person may cast a total
number of votes equal to the number of directors to be elected by the class or
series of stock held by such person multiplied by the number of votes to which
such person's shares are entitled, and may cast said total number of votes for
one or more candidates in such proportions as such person thinks fit; provided,
                                                                      --------
however, no shareholder shall be entitled to so cumulate such shareholder's
- -------
votes unless the candidates for which such shareholder is voting have been
placed in nomination prior to the voting and a shareholder has given notice at
the meeting, prior to the vote, of an intention to cumulate votes; provided,
                                                                   --------
further, that effective on the first date when the corporation has outstanding
- -------------
securities designated as qualified for trading as a national market system
security on the National Association of Securities Dealers Automated Quotation
System (or any successor national market system) and has at least 800 holders of
its equity securities as of the record date for its most recent annual meeting
of shareholders, the ability of shareholders to cumulate votes in the election
of directors shall be automatically eliminated. In any election of directors,
the candidates receiving the highest number of votes, up to the number of
directors to be elected, shall be elected.

     Each shareholder shall be entitled to that number of votes for each share
held as is set forth in the Articles of Incorporation of the corporation, as
amended or restated, except as may otherwise be required by law.

     Any shareholder may vote part of such shareholder's shares in favor of a
proposal and refrain from voting the remaining shares or vote them against the
proposal, other than elections to office, but, if the shareholder fails to
specify the number of shares such shareholder is voting affirmatively, it will
be conclusively presumed that the shareholder's approving vote is with respect
to all shares such shareholder is entitled to vote.

     No shareholder approval, other than unanimous approval of those entitled to
vote, will be valid as to proposals described in subsection 5(d) above, unless
the general nature of such business was stated in the notice of meeting or in
any written waiver of notice.

     SECTION 12.  PERSONS ENTITLED TO VOTE OR CONSENT.  The Board of Directors
may fix a record date pursuant to Section 3 of Article VIII of these bylaws to
determine which shareholders are entitled to notice of and to vote at a meeting
or consent to corporate actions, as provided in Sections 10 and 11 above. Only
persons in whose name shares otherwise entitled to vote stand on the stock
records of the corporation on such date shall be entitled to vote or consent.

     If no record date is fixed:

          (a)  The record date for determining shareholders entitled to notice
of or to vote at a meeting of shareholders shall be at the close of business on
the business day next preceding the day notice is given or, if notice is waived,
at the close of business on the business day next preceding the day on which the
meeting is held;

                                       8
<PAGE>
 
          (b)  The record date for determining shareholders entitled to give
consent to corporate action in writing without a meeting, when no prior action
by the Board of Directors has been taken, shall be the day on which the first
written consent is given;

          (c)  The record date for determining shareholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto, or the sixtieth (60th) day
prior to the date of such other action, whichever is later.

     A determination of shareholders of record entitled to notice of or to vote
at a meeting of shareholders shall apply to any adjournment of the meeting
unless the Board of Directors fixes a new record date for the adjourned meeting;
provided, however, that the Board of Directors shall fix a new record date if
the meeting is adjourned for more than forty-five (45) days from the date set
for the original meeting.

     Shares of the corporation held by its subsidiary or subsidiaries (as
defined in California Corporations Code, Section 189(b)) are not entitled to
vote in any matter.

     SECTION 13.  PROXIES.  Every person entitled to vote or execute consents
may do so either in person or by one or more agents authorized to act by a
written proxy executed by the person or such person's duly authorized agent and
filed with the Secretary of the corporation; provided that no such proxy shall
be valid after the expiration of eleven (11) months from the date of its
execution unless otherwise provided in the proxy. The manner of execution,
suspension, revocation, exercise and effect of proxies is governed by law.

     SECTION 14.  INSPECTORS OF ELECTION.  Before any meeting of shareholders,
the Board of Directors may appoint any persons, other than nominees for office,
to act as inspectors of election at the meeting or its adjournment. If no
inspectors of election are so appointed, the chairman of the meeting may, and on
the request of any shareholder or a shareholder's proxy shall, appoint
inspectors of election at the meeting. The number of inspectors shall be either
one (1) or three (3). If inspectors are appointed at a meeting on the request of
one or more shareholders or proxies, the majority of shares represented in
person or proxy shall determine whether one (1) or three (3) inspectors are to
be appointed. If any person appointed as inspector fails to appear or fails or
refuses to act, the chairman of the meeting may, and upon the request of any
shareholder or a shareholder's proxy shall, appoint a person to fill that
vacancy.

     These inspectors shall:

          (a)  Determine the number of shares outstanding and the voting power
of each, the shares represented at the meeting, the existence of a quorum, and
the authenticity, validity, and effect of proxies;

          (b)  Receive votes, ballots, or consents;

          (c)  Hear and determine all challenges and questions in any way
arising in connection with the right to vote;

                                       9
<PAGE>
 
          (d)  Count and tabulate all votes or consents;
          
          (e)  Determine when the polls shall close;

          (f)  Determine the result; and

          (g)  Do any other acts that may be proper to conduct the election or
vote with fairness to all shareholders.


                                  ARTICLE III
                               BOARD OF DIRECTORS

     SECTION 1.  POWERS.  Subject to the provisions of law or any limitations in
the Articles of Incorporation or these bylaws, as to action required to be
approved by the shareholders or by the outstanding shares, the business and
affairs of the corporation shall be managed and all corporate powers shall be
exercised, by or under the direction of the Board of Directors. The Board of
Directors may delegate the management of the day-to-day operation of the
business of the corporation to a management company or other person, provided
that the business and affairs of the corporation shall be managed and all
corporate powers shall be exercised under the ultimate direction of the Board of
Directors.

     SECTION 2.  NUMBER OF DIRECTORS.  The authorized number of directors of the
corporation shall be not less than a minimum of five (5) nor more than a maximum
of nine (9) (which maximum number in no case shall be greater than two times
said minimum, minus one) and the number of directors presently authorized is
five (5). The exact number of directors shall be set within these limits from
time to time (a) by approval of the Board of Directors, or (b) by the
affirmative vote of a majority of the voting power represented and voting at a
duly held meeting at which a quorum is present (which shares voting
affirmatively also constitute at least the required quorum) or by the written
consent of shareholders pursuant to Section 10 of Article II, above.

     Any amendment of these bylaws changing the maximum or minimum number of
directors may be adopted only by the affirmative vote of a majority of the
voting power; provided, an amendment reducing the minimum number of directors to
less than five (5), cannot be adopted if votes cast against its adoption at a
meeting or the shares not consenting to it in the case of action by written
consent are equal to more than 16-2/3 percent of the outstanding voting power.

     No reduction of the authorized number of directors shall remove any
director prior to the expiration of such director's term of office.

     SECTION 3.  ELECTION OF DIRECTORS, TERM, QUALIFICATIONS.  The directors
shall be elected at each annual meeting of shareholders to hold office until the
next annual meeting. Each director, including a director elected or appointed to
fill a vacancy, shall hold office either until the expiration of the term for
which elected or appointed and until a successor has been elected 

                                       10
<PAGE>
 
and qualified, or until his or her death, resignation or removal. Directors need
not be shareholders of the corporation.

     SECTION 4.  RESIGNATIONS.  Any director of the corporation may resign
effective upon giving written notice to the Chairman of the Board, the
President, the Secretary or the Board of Directors of the corporation, unless
the notice specifies a later time for the effectiveness of such resignation. If
the resignation specifies effectiveness at a future time, a successor may be
elected pursuant to Section 6 below, to take office on the date that the
resignation becomes effective.

     SECTION 5.  REMOVAL.  The Board of Directors may declare vacant the office
of a director who has been declared of unsound mind by an order of court or who
has been convicted of a felony.

     The entire Board of Directors or any individual director may be removed
from office without cause by the affirmative vote of a majority of the voting
power with respect to such removal; provided, however, that until such time as
cumulative voting is eliminated pursuant to Section 11 of Article II of these
Bylaws and Article V of the Articles of Incorporation, unless the entire Board
is removed, no individual director may be removed when the votes cast against
such director's removal, or not consenting in writing to such removal, would be
sufficient to elect that director if voted cumulatively at an election at which
the same total number of votes cast were cast (or, if such action is taken by
written consent, all shares entitled to vote were voted) and the entire number
of directors authorized at the time of such director's most recent election were
then being elected; provided, further, that if, in accordance with the
corporation's Articles of Incorporation, as amended or restated, the holders of
the shares of any class or series, voting as a class or series, are entitled to
elect one or more directors, any director so elected may be removed as set forth
in the Articles of Incorporation, except or as may otherwise be required by
applicable law.

     SECTION 6. VACANCIES.  Vacancies created by the death, resignation or
removal of a director may be filled as follows:

          (A)  Vacancies on the Board of Directors created by the death,
resignation or removal of a director who was elected by the holders of Class B
Common Stock may be filled by those directors (acting by majority vote, though
less than a quorum, or by the act of a sole remaining director) who were elected
by the holders of Class B Common Stock.

          (B)  Vacancies on the Board of Directors created by the death,
resignation or removal of a director who was elected by the holders of Class A
Common Stock, Class B Common Stock and Series A Convertible Preferred Stock, if
any, voting as a single class, may be filled by those directors (acting by
majority vote, though less than a quorum, or by the act of a sole remaining
director) who were elected by the holders of Class A Common Stock, Class B
Common Stock and Series A Convertible Preferred Stock, if any), voting as a
single class.

     Vacancies created by an increase in the authorized number of directors, or
a failure by the shareholders to elect the full authorized number of directors,
or any other reason that causes there to be fewer directors than the full
authorized number, may be filled by those directors (acting by 

                                       11
<PAGE>
 
majority vote, though less than a quorum, or by the act of a sole remaining
director) who were elected by the holders of such class (or classes) of shares
as would then be entitled to elect an additional director pursuant to the
corporation's Articles of Incorporation.

     The shareholders may elect a director at any time to fill any vacancy not
filled by the directors. Except as otherwise provided in the corporation's
Articles of Incorporation or as otherwise required by law, any such election by
written consent, other than to fill a vacancy created by removal, requires the
consent of a majority of the voting power with respect to such director. Except
as otherwise provided in the corporation's Articles of Incorporation or as
otherwise required by law, any such election by written consent to fill a
vacancy created by removal requires the consent of all of the voting power with
respect to such director.

     If, after the filling of any vacancy by the directors, the directors then
in office who have been elected by the shareholders constitute less than a
majority of the directors then in office, any holder or holders of an aggregate
of five percent (5%) or more of the voting power at that time and having the
right to vote for such directors may call a special meeting of shareholders to
be held to elect directors. The term of office of any director shall terminate
upon such election of a successor.

     SECTION 7.  REGULAR MEETINGS.  Immediately after each annual meeting of
shareholders, and at such place fixed by the Board of Directors, or if no such
place is fixed at the place of the annual meeting, the Board of Directors shall
hold a regular meeting for the purposes of organization, the appointment of
officers and the transaction of other business. Other regular meetings of the
Board of Directors shall be held at such times, places and dates as fixed in
these bylaws or by the Board of Directors; provided, however, that if the date
for such a meeting falls on a legal holiday, then the meeting shall be held at
the same time on the next succeeding full business day. Regular meetings of the
Board of Directors held pursuant to this Section 7 may be held without notice.

     SECTION 8.  PARTICIPATION BY TELEPHONE.  Members of the Board of Directors
may participate in a meeting through use of conference telephone or similar
communications equipment, so long as all members participating in such meeting
can hear one another. Such participation constitutes presence in person at such
meeting.

     SECTION 9.  SPECIAL MEETINGS.  Special meetings of the Board of Directors
for any purpose may be called by the Chairman of the Board or the President or
any vice president or the Secretary of the corporation or any two (2) directors.

     SECTION 10.  NOTICE OF MEETINGS.  Notice of the date, time and place of all
meetings of the Board of Directors, other than regular meetings held pursuant to
Section  7 above shall be delivered personally, orally or in writing, or by
telephone or telegraph to each director, at least forty-eight (48) hours before
the meeting, or sent in writing to each director by first-class mail, charges
prepaid, at least four (4) days before the meeting. Such notice may be given by
the Secretary of the corporation or by the person or persons who called a
meeting. Such notice need not specify the purpose of the meeting. Notice of any
meeting of the Board of Directors need not be given to any director who signs a
waiver of notice of such meeting, or a consent to holding the 

                                       12
<PAGE>
 
meeting or an approval of the minutes thereof, either before or after the
meeting, or who attends the meeting without protesting prior thereto or at its
commencement such director's lack of notice. All such waivers, consents and
approvals shall be filed with the corporate records or made a part of the
minutes of the meeting.

     SECTION 11.  PLACE OF MEETINGS.  Meetings of the Board of Directors may be
held at any place within or without the state which has been designated in the
notice of the meeting or, if not stated in the notice or there is no notice,
designated in the bylaws or by resolution of the Board of Directors.

     SECTION 12.  ACTION BY WRITTEN CONSENT WITHOUT A MEETING.  Any action
required or permitted to be taken by the Board of Directors may be taken without
a meeting, if all members of the Board of Directors individually or collectively
consent in writing to such action. Such written consent or consents shall be
filed with the minutes of the proceedings of the Board of Directors. Such action
by written consent shall have the same force and effect as a unanimous vote of
such directors.

     SECTION 13.  QUORUM AND TRANSACTION OF BUSINESS.  A majority of the
authorized number of directors shall constitute a quorum for the transaction of
business. Every act or decision done or made by a majority of the authorized
number of directors present at a meeting duly held at which a quorum is present
shall be the act of the Board of Directors, unless applicable law, the Articles
of Incorporation or these bylaws specifically require a greater number. A
meeting at which a quorum is initially present may continue to transact
business, notwithstanding withdrawal of directors, if any action taken is
approved by at least a majority of the number of directors constituting a quorum
for such meeting. In the absence of a quorum at any meeting of the Board of
Directors, a majority of the directors present may adjourn the meeting, as
provided in Section 14 below.

     SECTION 14.  ADJOURNMENT.  Any meeting of the Board of Directors, whether
or not a quorum is present, may be adjourned to another time and place by the
affirmative vote of a majority of the directors present. If the meeting is
adjourned for more than twenty-four (24) hours, notice of such adjournment to
another time or place shall be given prior to the time of the adjourned meeting
to the directors who were not present at the time of the adjournment.

     SECTION 15.  ORGANIZATION.  The Chairman of the Board shall preside at
every meeting of the Board of Directors, if present. If there is no Chairman of
the Board or if the Chairman is not present, a Chairman chosen by a majority of
the directors present shall act as chairman. The Secretary of the corporation
or, in the absence of the Secretary, any person appointed by the Chairman shall
act as secretary of the meeting.

     SECTION 16.  COMPENSATION.  Directors and members of committees may receive
such compensation, if any, for their services, and such reimbursement for
expenses, as may be fixed or determined by the Board of Directors.

     SECTION 17. COMMITTEES. The Board of Directors may, by resolution adopted
by a majority of the authorized number of directors, designate one or more
committees, each

                                       13
<PAGE>
 
consisting of two (2) or more directors, to serve at the pleasure of the Board
of Directors. The Board of Directors, by a vote of the majority of authorized
directors, may designate one or more directors as alternate members of any
committee, to replace any absent member at any meeting of such committee. Any
such committee shall have authority to act in the manner and to the extent
provided in the resolution of the Board of Directors, and may have all the
authority of the Board of Directors in the management of the business and
affairs of the corporation, except with respect to:

          a.  the approval of any action for which shareholders' approval or
approval of the outstanding shares also is required by the California
Corporations Code;

          b.  the filling of vacancies on the Board of Directors or any of its
committees;

          c.  the fixing of compensation of directors for serving on the Board
of Directors or any of its committees;

          d.  the adoption, amendment or repeal of these bylaws;

          e.  the amendment or repeal of any resolution of the Board of
Directors which by its express terms is not so amendable or repealable;

          f.  a distribution to shareholders, except at a rate or in a periodic
amount or within a price range determined by the Board of Directors; or

          g.  the appointment of other committees of the Board of Directors or
the members thereof.

     Any committee may from time to time provide by resolution for regular
meetings at specified times and places.  If the date of such a meeting falls on
a legal holiday, then the meeting shall be held at the same time on the next
succeeding full business day.  No notice of such a meeting need be given.  Such
regular meetings need not be held if the committee shall so determine at any
time before or after the time when such meeting would otherwise have taken
place.  Special meetings may be called at any time in the same manner and by the
same persons as stated in Sections 8 and 9, above for meetings of the Board of
Directors.  The provisions of Sections 7, 10, 11, 12, 13 and 14 above shall
apply to committees, committee members and committee meetings as if the words
"committee" and "committee member" were substituted for the word "Board of
Directors," and "director," respectively, throughout such sections.

                                  ARTICLE IV
                                   OFFICERS

     SECTION 1.  OFFICERS. The corporation shall have a Chairman of the Board,
Chief Executive Officer, President, Chief Operating Officer, Chief Financial
Officer, Secretary and such other officers with such titles and duties as the
Board of Directors may determine. Any two or more offices may be held by the
same person.

                                       14
<PAGE>
 
     SECTION 2.  APPOINTMENT. All officers shall be chosen and appointed by the
Board of Directors; provided, however, the Board of Directors may empower the
chief executive officer of the corporation to appoint such officers, other than
Chairman of the Board, President, Secretary or Chief Financial Officer, as the
business of the corporation may require. All officers shall serve at the
pleasure of the Board of Directors, subject to the rights, if any, of an officer
under a contract of employment.

     SECTION 3.  INABILITY TO ACT. In the case of absence or inability to act of
any officer of the corporation or of any person authorized by these bylaws to
act in such officer's place, the Board of Directors may from time to time
delegate the powers or duties of such officer to any other officer, or any
director or other person whom it may select, for such period of time as the
Board of Directors deems necessary.

     SECTION 4.  RESIGNATIONS. Any officer may resign at any time upon written
notice to the corporation, without prejudice to the rights, if any, of the
corporation under any contract to which such officer is a party. Such
resignation shall be effective upon its receipt by the Chairman of the Board,
the Chief Executive Officer or President, the Secretary or the Board of
Directors, unless a different time is specified in the notice for effectiveness
of such resignation. The acceptance of any such resignation shall not be
necessary to make it effective unless otherwise specified in such notice.

     SECTION 5.  REMOVAL. Any officer may be removed from office at any time,
with or without cause, but subject to the rights, if any, of such officer under
any contract of employment, by the Board of Directors or by any committee to
whom such power of removal has been duly delegated, or, with regard to any
officer who has been appointed by the chief executive officer pursuant to
Section 2 above, by the chief executive officer or any other officer upon whom
such power of removal may be conferred by the Board of Directors.

     SECTION 6.  VACANCIES. A vacancy occurring in any office for any cause may
be filled by the Board of Directors, in the manner prescribed by this Article of
the bylaws for initial appointment to such office.

     SECTION 7.  CHAIRMAN OF THE BOARD. The Chairman of the Board, if there be
such an officer, shall, if present, preside at all meetings of the Board of
Directors and shall exercise and perform such other powers and duties as may be
assigned from time to time by the Board of Directors or prescribed by these
bylaws. If no Chief Executive Officer or President is appointed, the Chairman of
the Board is the general manager and chief executive officer of the corporation,
and shall exercise all powers of the Chief Executive Officer or President
described in Section8 below.

     SECTION 8.  CHIEF EXECUTIVE OFFICER. Subject to such powers, if any, as may
be given by the Board of Directors to the Chairman of the Board, if there be
such an officer, the Chief Executive Officer (or the President, if so titled)
shall be the general manager and chief executive officer of the corporation and
shall have general supervision and control over the business and affairs of the
corporation, subject to the control of the Board of Directors. The Chief

               CONTRACTS, LOANS, BANK ACCOUNTS, CHECKS AND DRAFTS

     SECTION 1.  EXECUTION OF CONTRACTS AND OTHER INSTRUMENTS. Except as these
bylaws may otherwise provide, the Board of Directors or its duly appointed and
authorized committee may authorize any officer or officers, agent or agents, to
enter into any contract or execute and deliver any instrument in the name of and
on behalf of the corporation, and such authorization may be general or confined
to specific instances. Except as so authorized or otherwise expressly provided
in these bylaws, no officer, agent, or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or in any amount.

     SECTION 2.  LOANS. No loans shall be contracted on behalf of the
corporation and no negotiable paper shall be issued in its name, unless and
except as authorized by the Board of Directors or its duly appointed and
authorized committee. When so authorized by the Board of Directors or such
committee, any officer or agent of the corporation may effect loans and advances
at any time for the corporation from any bank, trust company, or other
institution, or from any firm, corporation or individual, and for such loans and
advances may make, execute and deliver promissory notes, bonds or other
evidences of indebtedness of the corporation and, when authorized as aforesaid,
may mortgage, pledge, hypothecate or transfer any and all stocks, securities and
other property, real or personal, at any time held by the corporation, and to
that end endorse, assign and deliver the same as security for the payment of any
and all loans, advances, indebtedness, and liabilities of the corporation. Such
authorization may be general or confined to specific instances.

     SECTION 3.  BANK ACCOUNTS. The Board of Directors or its duly appointed and
authorized committee from time to time may authorize the opening and keeping of
general and/or special bank accounts with such banks, trust companies, or other
depositories as may be selected by the Board of Directors, its duly appointed
and authorized committee or by any officer or officers, agent or agents, of the
corporation to whom such power may be delegated from time to time by the Board
of Directors. The Board of Directors or its duly appointed and authorized
committee 

                                       18
<PAGE>
 
may make such rules and regulations with respect to said bank accounts, not
inconsistent with the provisions of these bylaws, as are deemed advisable.

     SECTION 4.  CHECKS, DRAFTS, ETC. All checks, drafts or other orders for the
payment of money, notes, acceptances or other evidences of indebtedness issued
in the name of the corporation shall be signed by such officer or officers,
agent or agents, of the corporation, and in such manner, as shall be determined
from time to time by resolution of the Board of Directors or its duly appointed
and authorized committee. Endorsements for deposit to the credit of the
corporation in any of its duly authorized depositories may be made, without
countersignature, by the President or any vice president or the Chief Financial
Officer or any assistant financial officer or by any other officer or agent of
the corporation to whom the Board of Directors or its duly appointed and
authorized committee, by resolution, shall have delegated such power or by hand-
stamped impression in the name of the corporation.

                                   ARTICLE VI
                   CERTIFICATES FOR SHARES AND THEIR TRANSFER

     SECTION 1.  CERTIFICATE FOR SHARES. Every holder of shares in the
corporation shall be entitled to have a certificate signed in the name of the
corporation by the Chairman or Vice Chairman of the Board or the President or a
Vice President and by the Chief Financial Officer or an assistant financial
officer or by the Secretary or an assistant secretary, certifying the number of
shares and the class or series of shares owned by the shareholder. Any or all of
the signatures on the certificate may be facsimile. In case any officer,
transfer agent or registrar who has signed or whose facsimile signature has been
placed upon a certificate shall have ceased to be such officer, transfer agent
or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if such person were an officer, transfer
agent or registrar at the date of issue.

     In the event that the corporation shall issue any shares as only partly
paid, the certificate issued to represent such partly paid shares shall have
stated thereon the total consideration to be paid for such shares and the amount
paid thereon.

     SECTION 2.  TRANSFER ON THE BOOKS.  Upon surrender to the Secretary or
transfer agent (if any) of the corporation of a certificate for shares of the
corporation duly endorsed, with reasonable assurance that the endorsement is
genuine and effective, or accompanied by proper evidence of succession,
assignment or authority to transfer and upon compliance with applicable federal
and state securities laws and if the corporation has no statutory duty to
inquire into adverse claims or has discharged any such duty and if any
applicable law relating to the collection of taxes has been complied with, it
shall be the duty of the corporation, by its Secretary or transfer agent, to
cancel the old certificate, to issue a new certificate to the person entitled
thereto and to record the transaction on the books of the corporation.

     SECTION 3.  LOST, DESTROYED AND STOLEN CERTIFICATES. The holder of any
certificate for shares of the corporation alleged to have been lost, destroyed
or stolen shall notify the corpora-

                                       19
<PAGE>
 
tion by making a written affidavit or affirmation of such fact. Upon receipt of
said affidavit or affirmation the Board of Directors, or its duly appointed and
authorized committee or any officer or officers authorized by the board so to
do, may order the issuance of a new certificate for shares in the place of any
certificate previously issued by the corporation and which is alleged to have
been lost, destroyed or stolen. However, the Board of Directors or such
authorized committee, officer or officers may require the owner of the allegedly
lost, destroyed or stolen certificate, or such owner's legal representative, to
give the corporation a bond or other adequate security sufficient to indemnify
the corporation and its transfer agent and/or registrar, if any, against any
claim that may be made against it or them on account of such allegedly lost,
destroyed or stolen certificate or the replacement thereof. Said bond or other
security shall be in such amount, on such terms and conditions and, in the case
of a bond, with such surety or sureties as may be acceptable to the Board of
Directors or to its duly appointed and authorized committee or any officer or
officers authorized by the Board of Directors to determine the sufficiency
thereof. The requirement of a bond or other security may be waived in particular
cases at the discretion of the Board of Directors or its duly appointed and
authorized committee or any officer or officers authorized by the Board of
Directors so to do.

     SECTION 4.  ISSUANCE, TRANSFER AND REGISTRATION OF SHARES.  The Board
of Directors may make such rules and regulations, not inconsistent with law or
with these bylaws, as it may deem advisable concerning the issuance, transfer
and registration of certificates for shares of the capital stock of the
corporation.  The Board of Directors may appoint a transfer agent or registrar
of transfers, or both, and may require all certificates for shares of the
corporation to bear the signature of either or both.

                                  ARTICLE VII
                        INSPECTION OF CORPORATE RECORDS

     SECTION 1.  INSPECTION BY DIRECTORS.  Every director shall have the
absolute right at any reasonable time to inspect and copy all books, records,
and documents of every kind of the corporation and any of its subsidiaries and
to inspect the physical properties of the corporation and any of its
subsidiaries.  Such inspection may be made by the director in person or by agent
or attorney, and the right of inspection includes the right to copy and make
extracts.

     SECTION 2.  INSPECTION BY SHAREHOLDERS.

          A.  INSPECTION OF CORPORATE RECORDS.

              i.  A shareholder or shareholders holding at least five percent in
the aggregate of the outstanding voting shares of the corporation or who hold at
least one percent of such voting shares and have filed a Schedule 14A with the
United States Securities and Exchange Commission relating to the election of
directors of the corporation shall have an absolute right to do either or both
of the following:

                                       20
<PAGE>
 
                    (1)  Inspect and copy the record of shareholders' names and
addresses and shareholdings during usual business hours upon five business days'
prior written demand upon the corporation; or

                    (2)  Obtain from the transfer agent, if any, for the
corporation, upon five business days' prior written demand and upon the tender
of its usual charges for such a list (the amount of which charges shall be
stated to the shareholder by the transfer agent upon request), a list of the
shareholders' names and addresses who are entitled to vote for the election of
directors and their shareholdings, as of the most recent record date for which
it has been compiled or as of a date specified by the shareholder subsequent to
the date of demand.

               ii.  The record of shareholders shall also be open to inspection
and copying by any shareholder or holder of a voting trust certificate at any
time during usual business hours upon written demand on the corporation, for a
purpose reasonably related to such holder's interest as a shareholder or holder
of a voting trust certificate.

               iii. The accounting books and records and minutes of proceedings
of the shareholders and the Board of Directors and of any committees of the
Board of Directors of the corporation and of each of its subsidiaries shall be
open to inspection, copying and making extracts upon written demand on the
corporation of any shareholder or holder of a voting trust certificate at any
reasonable time during usual business hours, for a purpose reasonably related to
such holder's interests as a shareholder or as a holder of such voting trust
certificate.

               iv.  Any inspection, copying, and making of extracts under this
subsection (a) may be done in person or by agent or attorney.

          B.   INSPECTION OF BYLAWS.  The original or a copy of these bylaws
shall be kept as provided in Section12 of ArticleIV of these bylaws and shall
be open to inspection by the shareholders at all reasonable times during office
hours.  If the principal executive office of the corporation is not in
California, and the corporation has no principal business office in the state of
California, a current copy of these bylaws shall be furnished to any shareholder
upon written request.

     SECTION 3.  WRITTEN FORM. If any record subject to inspection pursuant to
Section2 above is not maintained in written form, a request for inspection is
not complied with unless and until the corporation at its expense makes such
record available in written form.

                                  ARTICLE VIII
                                 MISCELLANEOUS

     SECTION 1.  FISCAL YEAR. Unless otherwise fixed by resolution of the Board
of Directors, the fiscal year of the corporation shall end on the 30th day of
September in each calendar year.

                                       21
<PAGE>
 
     SECTION 2.  ANNUAL REPORT.

          a.  Subject to the provisions of subsection(b) below, the Board of
Directors shall cause an annual report to be sent to each shareholder of the
corporation in the manner provided in Section 6 of Article II of these bylaws
not later than one hundred twenty (120) days after the close of the
corporation's fiscal year.  Such report shall include a balance sheet as of the
end of such fiscal year and an income statement and statement of changes in
financial position for such fiscal year, accompanied by any report thereon of
independent accountants or, if there is no such report, the certificate of an
authorized officer of the corporation that such statements were prepared without
audit from the books and records of the corporation.  When there are more than
100 shareholders of record of the corporation's shares, as determined by Section
605 of the California Corporations Code, additional information as required by
Section 1501(b) of the California Corporations Code shall also be contained in
such report, provided that if the corporation has a class of securities subject
to the reporting requirements of Section13 of the Exchange Act, that Act shall
take precedence.  Such report shall be sent to shareholders at least fifteen
(15) days prior to the next annual meeting of shareholders after the end of the
fiscal year to which it relates.

          b.  If and so long as there are fewer than 100 holders of record of
the corporation's shares, the requirement of sending of an annual report to the
shareholders of the corporation is hereby expressly waived.

     SECTION 3.  RECORD DATE.  The Board of Directors may fix a time in the
future as a record date for the determination of the shareholders entitled to
notice of or to vote at any meeting or entitled to receive payment of any
dividend or other distribution or allotment of any rights or entitled to
exercise any rights in respect of any change, conversion or exchange of shares
or entitled to exercise any rights in respect of any other lawful action.  The
record date so fixed shall not be more than sixty (60) days nor less than ten
(10) days prior to the date of the meeting nor more than sixty (60) days prior
to any other action or event for the purpose of which it is fixed.  If no record
date is fixed, the provisions of Section11 of Article II of these bylaws shall
apply with respect to notice of meetings, votes, and consents and the record
date for determining shareholders for any other purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolutions
relating thereto, or the sixtieth (60th) day prior to the date of such other
action or event, whichever is later.

     Only shareholders of record at the close of business on the record date
shall be entitled to notice and to vote or to receive the dividend, distribution
or allotment of rights or to exercise the rights, as the case may be,
notwithstanding any transfer of any shares on the books of the corporation after
the record date, except as otherwise provided in the Articles of Incorporation,
by agreement or by law.

     SECTION 4.  BYLAW AMENDMENTS. Except as otherwise provided by law or
Section2 of ArticleIII of these bylaws, these bylaws may be amended or
repealed by the Board of Directors or by the affirmative vote of a majority of
the voting power; provided, however, after issuance of shares, a bylaw
specifying or changing a fixed number of directors or the maximum or minimum

                                       22
<PAGE>
 
number or changing from a fixed to a variable board or vice versa may only be
adopted by approval of the outstanding voting power as provided herein.

     SECTION 5.  CONSTRUCTION AND DEFINITION.  Unless the context requires
otherwise, the general provisions, rules of construction, and definitions
contained in the California Corporations Code shall govern the construction of
these bylaws.  Without limiting the foregoing, "shall" is mandatory and "may" is
permissive.

     SECTION 6.  CORPORATE SEAL. If the Board of Directors adopts a corporate
seal such seal shall have inscribed thereon the name of the corporation and the
state and date of its incorporation. If and when a seal is adopted by the Board
of Directors, such seal may be engraved, lithographed, printed, stamped,
impressed upon, or affixed to any contract, conveyance, certificate for shares,
or other instrument executed by the corporation.

                                   ARTICLE IX
                                INDEMNIFICATION

     SECTION 1.  INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND OTHER
AGENTS. 

          (a)  Directors. The corporation shall indemnify its directors to the
fullest extent not prohibited by the California General Corporation Law;
provided, however, that the corporation may limit the extent of such
indemnification by individual contracts with its directors; and, provided,
further, that the corporation shall not be required to indemnify any director in
connection with any proceeding (or part thereof) initiated by such person or any
proceeding by such person against the corporation or its directors, officers,
employees or other agents unless (i)such indemnification is expressly required
to be made by law, (ii)the proceeding was authorized by the board of directors
of the corporation, or (iii)such indemnification is provided by the
corporation, in its sole discretion, pursuant to the powers vested in the
corporation under the California General Corporation Law.

          (b)  Officers, Employees and Other Agents.  The corporation shall have
power to indemnify its officers, employees and other agents as set forth in the
California General Corporation Law.

          (c)  Determination by the Corporation.  Promptly after receipt of a
request for indemnification hereunder (and in any event within 90 days thereof)
a reasonable, good faith determination as to whether indemnification of the
director is proper under the circumstances because each director has met the
applicable standard of care shall be made by:

               (1)  a majority vote of a quorum consisting of directors who are
not parties to such proceeding;

               (2)  if such quorum is not obtainable, by independent legal
counsel in a written opinion; or

                                       23
<PAGE>
 
               (3)  approval or ratification by the affirmative vote of a
majority of the voting power represented and voting at a duly held meeting at
which a quorum is present (which shares voting affirmatively also constitute at
least the required quorum) or by written consent of a majority of the voting
power; where in each case the shares owned by the person to be indemnified shall
not be considered entitled to vote thereon.

          (d)  Good Faith.
          
               (1)  For purposes of any determination under this bylaw, a
director shall be deemed to have acted in good faith and in a manner he or she
reasonably believed to be in the best interests of the corporation and its
shareholders, and, with respect to any criminal action or proceeding, to have
had no reasonable cause to believe that his or her conduct was unlawful, if his
or her action is based on information, opinions, reports and statements,
including financial statements and other financial data, in each case prepared
or presented by:

                    (1)  one or more officers or employees of the corporation
whom the director believed to be reliable and competent in the matters
presented;

                    (2)  counsel, independent accountants or other persons as to
matters which the director believed to be within such person's professional
competence; and

                    (3)  a committee of the Board upon which such director does
not serve, as to matters within such committee's designated authority, which
committee the director believes to merit confidence; so long as, in each case,
the director acts without knowledge that would cause such reliance to be
unwarranted. 

               (2)  The termination of any proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere or its equivalent shall
not, of itself, create a presumption that the person did not act in good faith
and in a manner which he or she reasonably believed to be in the best interests
of the corporation and its shareholders or that he or she had reasonable cause
to believe that his conduct was unlawful.

               (3)  The provisions of this paragraph(d) shall not be deemed to
be exclusive or to limit in any way the circumstances in which a person may be
deemed to have met the applicable standard of conduct set forth by the
California General Corporation Law.

          (e)  Expenses.  The corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by any director in connection with such proceeding upon receipt of an
undertaking by or on behalf of such person to repay said amounts if it shall be
determined ultimately that such person is not entitled to be indemnified under
this bylaw or otherwise.

          (f)  Enforcement.  Without the necessity of entering into an express
contract, all rights to indemnification and advances to directors under this
bylaw shall be deemed to be contractual rights and be effective to the same
extent and as if provided for in a contract between the corporation and the
director.  Any right to indemnification or advances granted by this bylaw 

                                       24
<PAGE>
 
to a director shall be enforceable by or on behalf of the person holding such
right in the forum in which the proceeding is or was pending or, if such forum
is not available or a determination is made that such forum is not convenient,
in any court of competent jurisdiction if (i)the claim for indemnification or
advances is denied, in whole or in part, or (ii)no disposition of such claim is
made within ninety (90) days of request therefor. The claimant in such
enforcement action, if successful in whole or in part, shall be entitled to be
paid also the expense of prosecuting his or her claim. The corporation shall be
entitled to raise as a defense to any such action (other than an action brought
to enforce a claim for expenses incurred in connection with any proceeding in
advance of its final disposition when the required undertaking has been tendered
to the corporation) that the claimant has not met the standards of conduct that
make it permissible under the California General Corporation Law for the
corporation to indemnify the claimant for the amount claimed. Neither the
failure of the corporation (including its board of directors, independent legal
counsel or its shareholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in the California General Corporation Law, nor an actual determination
by the corporation (including its board of directors, independent legal counsel
or its shareholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct.

          (g)  Non-Exclusivity of Rights. To the fullest extent permitted by the
corporation's Articles of Incorporation and the California General Corporation
Law, the rights conferred on any person by this bylaw shall not be exclusive of
any other right which such person may have or hereafter acquire under any
statute, provision of the Articles of Incorporation, bylaws, agreement, vote of
shareholders or disinterested directors or otherwise, both as to action in his
or her official capacity and as to action in another capacity while holding
office. The corporation is specifically authorized to enter into individual
contracts with any or all of its directors, officers, employees or agents
respecting indemnification and advances, to the fullest extent permitted by the
California General Corporation Law and the corporation's Articles of
Incorporation.

          (h)  Survival of Rights.  The rights conferred on any person by this
bylaw shall continue as to a person who has ceased to be a director and shall
inure to the benefit of the heirs, executors and administrators of such a
person.
          (i)  Insurance.  The corporation, upon approval by the board of
directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this bylaw.

          (j)  Amendments.  Any repeal or modification of this bylaw shall only

suit or proceeding, whether civil, criminal, administrative, arbitrative or

was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this bylaw with respect to the resulting or surviving corporation as he or

================================================================================

PRINCIPAL AMOUNT: $2,250,000.00  INITIAL RATE: 9.750%    DATE OF NOTE: MARCH 13,
1997

PROMISE TO PAY.  TIER TECHNOLOGIES, INC. ("BORROWER") PROMISES TO PAY TO
WESTAMERICA BANK ("LENDER"), OR ORDER, IN LAWFUL MONEY OF THE UNITED STATES OF
AMERICA, THE PRINCIPAL AMOUNT OF TWO MILLION TWO HUNDRED FIFTY THOUSAND & 00/100
DOLLARS ($2,250,000.00) OR SO MUCH AS MAY BE OUTSTANDING, TOGETHER WITH INTEREST
ON THE UNPAID OUTSTANDING PRINCIPAL BALANCE OF EACH ADVANCE.  INTEREST SHALL BE
CALCULATED FROM THE DATE OF EACH ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT.  BORROWER WILL PAY THIS LOAN ON DEMAND, OR IF NO DEMAND IS MADE, IN ONE
PAYMENT OF ALL OUTSTANDING PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON MAY 31,
1998.  IN ADDITION, BORROWER WILL PAY REGULAR MONTHLY PAYMENTS OF ACCRUED UNPAID
INTEREST BEGINNING MARCH 31, 1997, AND ALL SUBSEQUENT INTEREST PAYMENTS ARE DUE
ON THE LAST DAY OF EACH MONTH AFTER THAT.  Interest on this Note is computed on
a 365/360 simple interest basis; that is, by applying the ratio of the annual
interest rate over a year of 360 days, multiplied by the outstanding principal
balance, multiplied by the actual number of days the principal balance is
outstanding.  Borrower will pay Lender at Lender's address shown above or at
such other place as Lender may designate in writing.  Unless otherwise agreed or
required by applicable law, payments will be applied first to accrued unpaid
interest, then to principal, and any remaining amount to any unpaid collection
costs and late charges.

VARIABLE INTEREST RATE.  The interest rate on this Note is subject to change
from time to time based on changes in an index which is the Westamerica Bank
Index Rate (the "Index").  THE BANK'S INDEX RATE IS ESTABLISHED BY BANK IN ITS
SAN RAFAEL HEADQUARTERS OFFICE AS OF THE DATE OF THIS NOTE, AND AS OF EACH DATE
THAT BANK MAY ADJUST SUCH INDEX RATE.  LOANS MAY BE MADE BY BANK AT, ABOVE OR
BELOW THE INDEX RATE.  Lender will tell Borrower the current Index rate upon
Borrower's request.  Borrower understands that Lender may make loans based on
other rates as well.  The interest rate change will not occur more often than
each Day.  THE INDEX CURRENTLY IS 8.250% PER ANNUM.  THE INTEREST RATE TO BE
APPLIED TO THE UNPAID PRINCIPAL BALANCE OF THIS NOTE WILL BE AT A RATE OF 1.500
PERCENTAGE POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 9.750% PER
ANNUM.  NOTICE: Under no circumstances will the interest rate on this Note be
more than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE.  Borrower agrees that all loan fees and
other prepaid finance charges are earned fully as of the date of the loan and
will not be subject to refund upon early payment (whether voluntary or as a
result of default), except as otherwise required by law. In any event, even upon
full prepayment of this Note, Borrower understands that Lender is entitled to a
minimum Interest charge of $50.00. Other than Borrower's obligation to pay any
minimum interest charge, Borrower may pay all or a portion of the amount owed
earlier than it is due.  Early payments will not, unless agreed to by Lender in
writing, relieve Borrower of Borrower's obligation to continue to make payments
under the payment schedule.  Rather, they will reduce the principal balance due
and may result in Borrower's making fewer payments.

DEFAULT.  Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Borrower defaults under any loan, extension of credit,
security agreement, purchase or sales agreement, or any other agreement, in
favor of any other creditor or person that may materially affect any of
Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents. (d) Any
representation or statement made or furnished to Lender by Borrower or on
Borrower's behalf is false or misleading in any material

================================================================================

respect either now or at the time made or furnished. (e) Borrower becomes
insolvent, a receiver is appointed for any part of Borrower's property, Borrower
makes an assignment for the benefit of creditors, or any proceeding is commenced
either by Borrower or against Borrower under any bankruptcy or insolvency laws.
(f) Any creditor tries to take any of Borrower's property on or in which Lender
has a lien or security interest. This includes a garnishment of any of
Borrower's accounts with Lender. (g) Any guarantor dies or any of the other
events described in this default section occurs with respect to any guarantor of
this Note. (h) A material adverse change occurs in Borrower's financial
condition, or Lender believes the prospect of payment or performance of the
Indebtedness is impaired.

LENDER'S RIGHTS.  Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount.  Upon Borrower's failure to pay
all amounts declared due pursuant to this section, including failure to pay upon
final maturity, Lender, at its option, may also, if permitted under applicable
law, increase the variable interest rate on this Note to 5.500 percentage points
over the Index.  Lender may hire or pay someone else to help collect this Note
if Borrower does not pay.  Borrower also will pay Lender that amount.  This
includes, subject to any limits under applicable law, Lender's attorneys' fees
and Lender's legal expenses whether or not there is a lawsuit, including
attorneys' fees and legal expenses for bankruptcy proceedings (including efforts
to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgment collection services.  Borrower also will pay any court
costs, in addition to all other sums provided by law.  THIS NOTE HAS BEEN
DELIVERED TO LENDER AND ACCEPTED BY LENDER IN THE STATE OF CALIFORNIA.  IF THERE
IS A LAWSUIT, BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE
JURISDICTION OF THE COURTS OF MARIN COUNTY, THE STATE OF CALIFORNIA.  LENDER AND
BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR
COUNTERCLAIM BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER.  THIS NOTE
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
CALIFORNIA.

DISHONORED ITEM FEE.  Borrower will pay a fee to Lender of $15.00 if Borrower
makes a payment on Borrower's loan and the check or preauthorized charge with
which Borrower pays is later dishonored.

COLLATERAL.  This Note is secured by THAT CERTAIN COMMERCIAL SECURITY AGREEMENT
DATED MARCH 13,1997.

LINE OF CREDIT.  This Note evidences a revolving line of credit.  Advances under
this Note may be requested either orally or in writing by Borrower or by an
authorized person.  Lender may, but need not, require that all oral requests be
confirmed in writing.  All communications, instructions, or directions by
telephone or otherwise to Lender are to be directed to Lender's office shown
above.  The following party or parties are authorized to request advances under
the line of credit until Lender receives from Borrower at Lender's address shown
above written notice of revocation of their authority: WILLIAM G. BARTON,
PRESIDENT; JAMES L. BILDNER, CHAIRMAN; AND GEORGE ROSS, SVP/CFO.  Borrower
agrees to be liable for all sums either: (a) advanced in accordance with the
instructions of an authorized person or (b) credited to any of Borrower's
accounts with Lender.  The unpaid principal balance owing on this Note at any
time may be evidenced by endorsements on this Note or by Lender's internal
records, including daily computer print-outs.  Lender will have no obligation to
advance funds under this Note if: (a) Borrower or any guarantor is in default
under the terms of this Note or any agreement that Borrower or any guarantor has
with Lender, including any agreement made in connection with the signing of this
Note; (b) Borrower or any guarantor ceases doing business or is insolvent; (c)
any guarantor seeks, claims or otherwise attempts to limit, modify or revoke
such guarantor's guarantee of this Note or any other loan with Lender; or (d)
Borrower has applied funds provided pursuant to this Note for purposes other
than those authorized by Lender.

LOAN NO 704-00488                      (CONTINUED)

================================================================================

ATTORNEYS' FEES INCLUDE, WITHOUT LIMITATION, ATTORNEYS' FEES WHETHER OR NOT
THERE IS A LAWSUIT, AND IF THERE IS A LAWSUIT, ANY FEES AND COSTS FOR TRIAL AND
APPEALS.

The above limitation on liability is not a restriction on the amount of the
Indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative.  This Guaranty shall not (unless specifically provided
below to the contrary) affect or invalidate any such other guaranties.  The
liability of Guarantor will be the aggregate liability of Guarantor under the
terms of this Guaranty and any such other unterminated guaranties.

NATURE OF GUARANTY.  Guarantor's liability under this Guaranty shall be open and
continuous for so long as this Guaranty remains in force.  Guarantor intends to
guarantee at all times the performance and prompt payment when due, whether at
maturity or earlier by reason of acceleration or otherwise, of all Indebtedness
within the limits set forth in the preceding section of this Guaranty.
Accordingly, no payments made upon the Indebtedness will discharge or diminish
the continuing liability of Guarantor in connection with any remaining portions
of the Indebtedness or any of the Indebtedness which subsequently arises or is
thereafter incurred or contracted.  Any married person who signs this Guaranty
hereby expressly agrees that recourse under this agreement may be had against
both his or her separate property and community property, whether now owned or
hereafter acquired.

DURATION OF GUARANTY.  This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by Lender of any notice of revocation shall have been
fully and finally paid and satisfied and all other obligations of Guarantor
under this Guaranty shall have been performed in full.  If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing.  Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at the address
of Lender listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by Lender of Guarantor's written
revocation.  For this purpose and without limitation, the term "new
Indebtedness" does not include Indebtedness which at the time of notice of
revocation is contingent, unliquidated, undetermined or not due and which later
becomes absolute, liquidated, determined or due.  This Guaranty will continue to
bind Guarantor for all Indebtedness incurred by Borrower or committed by Lender
prior to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness.  All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness.  This Guaranty shall
bind the estate of Guarantor as to Indebtedness created both before and after
the death or incapacity of Guarantor, regardless of Lender's actual notice of
Guarantor's death.  Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect.  Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty.  A revocation received by Lender from any one or more Guarantors shall
not affect the liability of any remaining Guarantors under this Guaranty.  IT IS
ANTICIPATED THAT FLUCTUATIONS MAY OCCUR IN THE AGGREGATE AMOUNT OF INDEBTEDNESS
COVERED BY THIS GUARANTY, AND IT IS SPECIFICALLY ACKNOWLEDGED AND AGREED BY
GUARANTOR THAT REDUCTIONS IN THE AMOUNT OF INDEBTEDNESS, EVEN TO ZERO DOLLARS
($0.00), PRIOR TO WRITTEN REVOCATION OF THIS GUARANTY BY GUARANTOR SHALL NOT
CONSTITUTE A TERMINATION OF THIS GUARANTY.  THIS GUARANTY IS BINDING UPON
GUARANTOR AND GUARANTOR'S HEIRS, SUCCESSORS AND ASSIGNS SO LONG AS ANY OF THE
GUARANTEED INDEBTEDNESS REMAINS UNPAID AND EVEN THOUGH THE INDEBTEDNESS
GUARANTEED MAY FROM TIME TO TIME BE ZERO DOLLARS ($0.00).

GUARANTOR'S AUTHORIZATION TO LENDER.  GUARANTOR AUTHORIZES LENDER, EITHER BEFORE
OR AFTER ANY REVOCATION HEREOF, WITHOUT NOTICE OR DEMAND AND WITHOUT LESSENING
GUARANTOR'S LIABILITY UNDER THIS GUARANTY, FROM TIME TO TIME:  (A) PRIOR TO
REVOCATION AS SET FORTH ABOVE, TO MAKE ONE OR MORE ADDITIONAL SECURED OR
UNSECURED LOANS TO BORROWER, TO LEASE EQUIPMENT OR OTHER GOODS TO BORROWER, OR
OTHERWISE TO EXTEND ADDITIONAL CREDIT TO BORROWER; (B) TO ALTER, COMPROMISE,
RENEW, EXTEND, ACCELERATE, OR OTHERWISE CHANGE ONE OR MORE TIMES THE TIME FOR
PAYMENT OR OTHER TERMS OF THE INDEBTEDNESS OR ANY PART OF THE INDEBTEDNESS,
INCLUDING INCREASES AND DECREASES OF THE RATE OF

to Guarantor which would limit or qualify in any way the terms of this Guaranty;
(b) this Guaranty is executed at Borrower's request and not at the request of
Lender; (c) Guarantor has full power, right and authority to enter into this

written consent of Lender, sell, lease, assign, encumber, hypothecate, transfer,
or otherwise dispose of all or substantially all of Guarantor's assets, or any

financial and credit information in form acceptable to Lender, and all such
financial information which currently has been, and all future financial
information which will be provided to Lender is and will be true and correct in
all material respects and fairly present the financial condition of Guarantor as
of the dates the financial information is provided; (g) no material adverse
change has occurred in Guarantor's financial condition since the date of the
most recent financial statements provided to Lender and no event has occurred
which may materially adversely affect Guarantor's financial condition; (h) no
litigation, claim, investigation, administrative proceeding or similar action
(including those for unpaid taxes) against Guarantor is pending or threatened;
(i) Lender has made no representation to Guarantor as to the creditworthiness of
Borrower; and (j) Guarantor has established adequate means of obtaining from
Borrower on a continuing basis information regarding Borrower's financial
condition.  Guarantor agrees to keep adequately informed from such means of any
facts, events, or circumstances which might in any way affect Guarantor's risks
under this Guaranty, and Guarantor further agrees that, absent a request for
information, Lender shall have no obligation to disclose to Guarantor any
information or documents acquired by Lender in the course of its relationship
with Borrower.

GUARANTOR'S WAIVERS.  Except as prohibited by applicable law, Guarantor waives
any right to require Lender to (a) make any presentment, protest, demand, or
notice of any kind, including notice of change of any terms of repayment of the
Indebtedness, default by Borrower or any other guarantor or surety, any action
or nonaction taken by Borrower, Lender, or any other guarantor or surety of
Borrower, or the creation of new or additional Indebtedness; (b) proceed against
any person, including Borrower, before proceeding against Guarantor; (c) proceed
against any collateral for the Indebtedness, including Borrower's collateral,
before proceeding against Guarantor; (d) apply any payments or proceeds received
against the Indebtedness in any order; (e) give notice of the terms, time, and
place of any sale of the collateral pursuant to the Uniform Commercial Code or
any other law governing such sale; (f) disclose any information about the
Indebtedness, the Borrower, the collateral, or any other guarantor or surety, or
about any action or nonaction of Lender; or (g) pursue any remedy or course of
action in Lender's power whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (h)
any disability or other defense of Borrower, any other guarantor or surety or
any other person; (i) the cessation from any cause whatsoever, other than
payment in full, of the Indebtedness; (j) the application of proceeds of the
Indebtedness by Borrower for purposes other than the purposes understood and
intended by Guarantor and Lender; (k) any act of omission or commission by
Lender which directly or indirectly results in or contributes to the discharge
of Borrower or any other guarantor or surety, or the Indebtedness, or the loss
or release of any collateral by operation of law or otherwise; (l) any statute
of limitations in any action under this Guaranty or on the Indebtedness; or (m)

without limitation, the renewal,

================================================================================

extension, acceleration, or other change in the time payment of the Indebtedness
is due and any change in the interest rate, and including any such modification
or change in terms after revocation of this Guaranty on Indebtedness incurred
prior to such revocation.

Guarantor waives all rights and any defenses arising out of an election of
remedies by Lender even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for a guaranteed obligation, has destroyed
Guarantor's rights of subrogation and reimbursement against Borrower by
operation of Section 580d of the California Code of Civil Procedure or
otherwise.

Guarantor waives all rights and defenses that Guarantor may have because
Borrower's obligation is secured by real property.  This means among other
things: (1) Lender may collect from Guarantor without first foreclosing on any
real or personal property collateral pledged by Borrower. (2) If Lender
forecloses on any real property collateral pledged by Borrower: (A) The amount
of Borrower's obligation may be reduced only by the price for which the
collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price. (B) Lender may collect from Guarantor even if Lender, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from Borrower.  This is an unconditional waiver of any
rights and defenses Guarantor may have because Borrower's obligation is secured
by real property.  These rights and defenses include, but are not limited to,
any rights and defenses based upon Section 580a, 580b, 580d, or 726 of the Code
of Civil Procedure.

Guarantor understands and agrees that the foregoing waivers are waivers of
substantive rights and defenses to which Guarantor might otherwise be entitled
under state and federal law.  The rights and defenses waived include, without
limitation, those provided by California laws of suretyship and guaranty, anti-
deficiency laws, and the Uniform Commercial Code.  Guarantor acknowledges that
Guarantor has provided these waivers of rights and defenses with the intention
that they be fully relied upon by Lender.  Until all Indebtedness is paid in
full, Guarantor waives any right to enforce any remedy Lender may have against
Borrower or any other guarantor, surety, or other person, and further, Guarantor
waives any right to participate in any collateral for the Indebtedness now or
hereafter held by Lender.

If now or hereafter (a) Borrower shall be or become insolvent, and (b) the
Indebtedness shall not at all times until paid be fully secured by collateral
pledged by Borrower, Guarantor hereby forever waives and relinquishes in favor
of Lender and Borrower, and their respective successors, any claim or right to
payment Guarantor may now have or hereafter have or acquire against Borrower, by
subrogation or otherwise, so that at no time shall Guarantor be or become a
"creditor' of Borrower within the meaning of 11 U.S.C. section 547(b), or any
successor provision of the Federal bankruptcy laws.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS.  Guarantor warrants and
agrees that each of the waivers set forth above is made with Guarantor's full
knowledge of its significance and consequences and that, under the
circumstances, the waivers are reasonable and not contrary to public policy or
law.  If any such waiver is determined to be contrary to any applicable law or
public policy, such waiver shall be effective only to the extent permitted by
law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR.  Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter created,
shall be prior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent.  Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower.  In the event of insolvency and consequent liquidation of the assets
of Borrower, through bankruptcy, by an assignment for the benefit of creditors,
by voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims of both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the Indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that such assignment shall be effective only for the purpose
of assuring to Lender full payment in legal tender of the Indebtedness.  If
Lender so

================================================================================

requests, any notes or credit agreements now or hereafter evidencing any debts
or obligations of Borrower to Guarantor shall be marked with a legend that the
same are subject to this Guaranty and shall be delivered to Lender. Guarantor
agrees, and Lender hereby is authorized, in the name of Guarantor, from time to
time to execute and file financing statements and continuation statements and to
execute such other documents and to take such other actions as Lender deems
necessary or appropriate to perfect, preserve and enforce its rights under this
Guaranty.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Guaranty:

     INTEGRATION, AMENDMENT. Guarantor warrants, represents and agrees that this
     Guaranty, together with any exhibits or schedules incorporated herein,
     fully incorporates the agreements and understandings of Guarantor with
     Lender with respect to the subject matter hereof and all prior
     negotiations, drafts, and other extrinsic communications between Guarantor
     and Lender shall have no evidentiary effect whatsoever. Guarantor further
     agrees that Guarantor has read and fully understands the terms of this
     Guaranty; Guarantor has had the opportunity to be advised by Guarantor's
     attorney with respect to this Guaranty; the Guaranty fully reflects
     Guarantor's intentions and parol evidence is not required to interpret the
     terms of this Guaranty. Guarantor hereby indemnifies and holds Lender
     harmless from all losses, claims, damages, and costs (including Lender's
     attorneys' fees) suffered or incurred by Lender as a result of any breach
     by Guarantor of the warranties, representations and agreements of this
     paragraph. No alteration or amendment to this Guaranty shall be effective
     unless given in writing and signed by the parties sought to be charged or
     bound by the alteration or amendment.

     APPLICABLE LAW. This Guaranty has been delivered to Lender and accepted by
     Lender in the State of California. If there is a lawsuit, Guarantor agrees
     upon Lender's request to submit to the jurisdiction of the courts of MARIN
     County, State of California. Lender and Guarantor hereby waive the right to
     any jury trial in any action, proceeding, or counterclaim brought by either
     Lender or Guarantor against the other. This Guaranty shall be governed by
     and construed in accordance with the laws of the State of California.

     ATTORNEYS' FEES; EXPENSES. Guarantor agrees to pay upon demand all of
     Lender's costs and expenses, including attorneys' fees and Lender's legal
     expenses, incurred in connection with the enforcement of this Guaranty.
     Lender may pay someone else to help enforce this Guaranty, and Guarantor
     shall pay the costs and expenses of such enforcement. Costs and expenses
     include Lender's attorneys' fees and legal expenses whether or not there is
     a lawsuit, including attorneys' fees and legal expenses for bankruptcy
     proceedings (and including efforts to modify or vacate any automatic stay
     or injunction), appeals, and any anticipated post-judgment collection
     services. Guarantor also shall pay all court costs and such additional fees
     as may be directed by the court.

     NOTICES. All notices required to be given by either party to the other
     under this Guaranty shall be in writing, may be sent by telefacsimile, and,
     except for revocation notices by Guarantor, shall be effective when
     actually delivered or when deposited with a nationally recognized overnight
     courier, or when deposited in the United States mail, first class postage
     prepaid, addressed to the party to whom the notice is to be given at the
     address shown above or to such other addresses as either party may
     designate to the other in writing. All revocation notices by Guarantor
     shall be in writing and shall be effective only upon delivery to Lender as
     provided above in the section titled "DURATION OF GUARANTY." If there is
     more than one Guarantor, notice to any Guarantor will constitute notice to
     all Guarantors. For notice purposes, Guarantor agrees to keep Lender
     informed at all times of Guarantor's current address.

     INTERPRETATION. In all cases where there is more than one Borrower or
     Guarantor, then all words used in this Guaranty in the singular shall be
     deemed to have been used in the plural where the context and construction
     so require; and where there is more than one Borrower named in this
     Guaranty or when this Guaranty is executed by more than one Guarantor, the
     words "Borrower" and "Guarantor" respectively shall mean all and any one or
     more of them. The words "Guarantor," "Borrower," and "Lender" include the
     heirs, successors, assigns, and transferees of each of them. Caption
     headings in this Guaranty are for convenience purposes

     only and are not to be used to interpret or define the provisions of this
     Guaranty. If a court of competent jurisdiction finds any provision of this
     Guaranty to be invalid or unenforceable as to any person or circumstance,
     such finding shall not render that provision invalid or unenforceable as to
     any other persons or circumstances, and all provisions of this Guaranty in
     all other respects shall remain valid and enforceable. If any one or more
     of Borrower or Guarantor are corporations or partnerships, it is not
     necessary for Lender to inquire into the powers of Borrower or Guarantor or
     of the officers, directors, partners, or agents acting or purporting to act
     on their behalf, and any Indebtedness made or created in reliance upon the
     professed exercise of such powers shall be guaranteed under this Guaranty.

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Guaranty unless such waiver is given in writing and signed by Lender. No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender of
     a provision of this Guaranty shall not prejudice or constitute a waiver of
     Lender's right otherwise to demand strict compliance with that provision or
     any other provision of this Guaranty. No prior waiver by Lender, nor any
     course of dealing between Lender and Guarantor, shall constitute a waiver
     of any of Lender's rights or of any of Guarantor's obligations as to any
     future transactions. Whenever the consent of Lender is required under this
     Guaranty, the granting of such consent by Lender in any instance shall not
     constitute continuing consent to subsequent instances where such consent is
     required and in all cases such consent may be granted or withheld in the
     sole discretion of Lender.

EACH UNDERSIGNED GUARANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS
GUARANTY AND AGREES TO ITS TERMS.  IN ADDITION, EACH GUARANTOR UNDERSTANDS THAT
THIS GUARANTY IS EFFECTIVE UPON GUARANTOR'S EXECUTION AND DELIVERY OF THIS
GUARANTY TO LENDER AND THAT THE GUARANTY WILL CONTINUE UNTIL TERMINATED IN THE
MANNER SET FORTH IN THE SECTION TITLED "DURATION OF GUARANTY." NO FORMAL
ACCEPTANCE BY LENDER IS NECESSARY TO MAKE THIS GUARANTY EFFECTIVE.  THIS
GUARANTY IS DATED MARCH 13,1997.

FEES INCURRED IN CONNECTION WITH OR RELATING TO (A) THE COLLECTION OF THE

LOAN NO 704-00488                      (CONTINUED)

================================================================================

ATTORNEYS' FEES INCLUDE, WITHOUT LIMITATION, ATTORNEYS' FEES WHETHER OR NOT
THERE IS A LAWSUIT, AND IF THERE IS A LAWSUIT, ANY FEES AND COSTS FOR TRIAL AND
APPEALS.

The above limitation on liability is not a restriction on the amount of the
Indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative.  This Guaranty shall not (unless specifically provided
below to the contrary) affect or invalidate any such other guaranties.  The
liability of Guarantor will be the aggregate liability of Guarantor under the
terms of this Guaranty and any such other unterminated guaranties.

NATURE OF GUARANTY.  Guarantor's liability under this Guaranty shall be open and
continuous for so long as this Guaranty remains in force.  Guarantor intends to
guarantee at all times the performance and prompt payment when due, whether at
maturity or earlier by reason of acceleration or otherwise, of all Indebtedness
within the limits set forth in the preceding section of this Guaranty.
Accordingly, no payments made upon the Indebtedness will discharge or diminish
the continuing liability of Guarantor in connection with any remaining portions
of the Indebtedness or any of the Indebtedness which subsequently arises or is
thereafter incurred or contracted.  Any married person who signs this Guaranty
hereby expressly agrees that recourse may be had against both his or her
separate property and community property.

DURATION OF GUARANTY.  This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by Lender of any notice of revocation shall have been
fully and finally paid and satisfied and all other obligations of Guarantor
under this Guaranty shall have been performed in full.  If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing.  Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at the address
of Lender listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by Lender of Guarantor's written
revocation.  For this purpose and without limitation, the term "new
Indebtedness" does not include Indebtedness which at the time of notice of
revocation is contingent, unliquidated, undetermined or not due and which later
becomes absolute, liquidated, determined or due.  This Guaranty will continue to
bind Guarantor for all Indebtedness incurred by Borrower or committed by Lender
prior to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness.  All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness.  This Guaranty shall
bind the estate of Guarantor as to Indebtedness created both before and after
the death or incapacity of Guarantor, regardless of Lender's actual notice of
Guarantor's death.  Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect.  Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty.  A revocation received by Lender from any one or more Guarantors shall
not affect the liability of any remaining Guarantors under this Guaranty.  IT IS
ANTICIPATED THAT FLUCTUATIONS MAY OCCUR IN THE AGGREGATE AMOUNT OF INDEBTEDNESS
COVERED BY THIS GUARANTY, AND IT IS SPECIFICALLY ACKNOWLEDGED AND AGREED BY
GUARANTOR THAT REDUCTIONS IN THE AMOUNT OF INDEBTEDNESS, EVEN TO ZERO DOLLARS
($0.00), PRIOR TO WRITTEN REVOCATION OF THIS GUARANTY BY GUARANTOR SHALL NOT
CONSTITUTE A TERMINATION OF THIS GUARANTY.  THIS GUARANTY IS BINDING UPON
GUARANTOR AND GUARANTOR'S HEIRS, SUCCESSORS AND ASSIGNS SO LONG AS ANY OF THE
GUARANTEED INDEBTEDNESS REMAINS UNPAID AND EVEN THOUGH THE INDEBTEDNESS
GUARANTEED MAY FROM TIME TO TIME BE ZERO DOLLARS ($0.00).

GUARANTOR'S AUTHORIZATION TO LENDER.  Guarantor authorizes Lender, either before
or after any revocation hereof, WITHOUT NOTICE OR DEMAND AND WITHOUT LESSENING
GUARANTOR'S LIABILITY UNDER THIS GUARANTY, FROM TIME TO TIME: (A) PRIOR TO
REVOCATION AS SET FORTH ABOVE, TO MAKE ONE OR MORE ADDITIONAL SECURED OR
UNSECURED LOANS TO BORROWER, TO LEASE EQUIPMENT OR OTHER GOODS TO BORROWER, OR
OTHERWISE TO EXTEND ADDITIONAL CREDIT TO BORROWER; (B) TO ALTER, COMPROMISE,
RENEW, EXTEND, ACCELERATE, OR OTHERWISE CHANGE ONE OR MORE TIMES THE TIME FOR
PAYMENT OR OTHER TERMS OF THE INDEBTEDNESS OR ANY PART OF THE INDEBTEDNESS,
INCLUDING INCREASES AND DECREASES OF THE RATE OF

INTEREST ON THE INDEBTEDNESS; EXTENSIONS MAY BE REPEATED AND MAY BE FOR LONGER

IN ALL OR ANY PART OF THE INDEBTEDNESS; AND (H) TO ASSIGN OR TRANSFER THIS
GUARANTY IN WHOLE OR IN PART.

GUARANTOR'S REPRESENTATIONS AND WARRANTIES.  Guarantor represents and warrants
to Lender that (a) no representations or agreements of any kind have been made
to Guarantor which would limit or qualify in any way the terms of this Guaranty;
(b) this Guaranty is executed at Borrower's request and not at the request of
Lender; (c) Guarantor has full power, right and authority to enter into this
Guaranty; (d) the provisions of this Guaranty do not conflict with or result in
a default under any agreement or other instrument binding upon Guarantor and do

written consent of Lender, sell, lease, assign, encumber, hypothecate, transfer,
or otherwise dispose of all or substantially all of Guarantor's assets, or any
interest therein; (f) upon Lender's request, Guarantor will provide to Lender
financial and credit information in form acceptable to Lender, and all such
financial information which currently has been, and all future financial
information which will be provided to Lender is and will be true and correct in
all material respects and fairly present the financial condition of Guarantor as
of the dates the financial information is provided; (g) no material adverse
change has occurred in Guarantor's financial condition since the date of the
most recent financial statements provided to Lender and no event has occurred
which may materially adversely affect Guarantor's financial condition; (h) no
litigation, claim, investigation, administrative proceeding or similar action
(including those for unpaid taxes) against Guarantor is pending or threatened;
(i) Lender has made no representation to Guarantor as to the creditworthiness of
Borrower; and (j) Guarantor has established adequate means of obtaining from
Borrower on a continuing basis information regarding Borrower's financial
condition.  Guarantor agrees to keep adequately informed from such means of any
facts, events, or circumstances which might in any way affect Guarantor's risks
under this Guaranty, and Guarantor further agrees that, absent a request for
information, Lender shall have no obligation to disclose to Guarantor any
information or documents acquired by Lender in the course of its relationship
with Borrower.

GUARANTOR'S WAIVERS.  Except as prohibited by applicable law, Guarantor waives
any right to require Lender to (a) make any presentment, protest, demand, or
notice of any kind, including notice of change of any terms of repayment of the
Indebtedness, default by Borrower or any other guarantor or surety, any action
or nonaction taken by Borrower, Lender, or any other guarantor or surety of
Borrower, or the creation of new or additional Indebtedness; (b) proceed against
any person, including Borrower, before proceeding against Guarantor; (c) proceed
against any collateral for the Indebtedness, including Borrower's collateral,
before proceeding against Guarantor; (d) apply any payments or proceeds received
against the Indebtedness in any order; (e) give notice of the terms, time, and
place of any sale of the collateral pursuant to the Uniform Commercial Code or
any other law governing such sale; (f) disclose any information about the
Indebtedness, the Borrower, the collateral, or any other guarantor or surety, or
about any action or nonaction of Lender; or (g) pursue any remedy or course of
action in Lender's power whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (h)
any disability or other defense of Borrower, any other guarantor or surety or
any other person; (i) the cessation from any cause whatsoever, other than
payment in full, of the Indebtedness; (j) the application of proceeds of the
Indebtedness by Borrower for purposes other than the purposes understood and
intended by Guarantor and Lender; (k) any act of omission or commission by
Lender which directly or indirectly results in or contributes to the discharge
of Borrower or any other guarantor or surety, or the Indebtedness, or the loss
or release of any collateral by operation of law or otherwise; (l) any statute
of limitations in any action under this Guaranty or on the Indebtedness; or (m)
any modification or change in terms of the Indebtedness, whatsoever, including
without limitation, the renewal,

================================================================================

extension, acceleration, or other change in the time payment of the Indebtedness
is due and any change in the interest rate, and including any such modification
or change in terms after revocation of this Guaranty on Indebtedness incurred
prior to such revocation.

Guarantor waives all rights and any defenses arising out of an election of
remedies by Lender even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for a guaranteed obligation, has destroyed
Guarantor's rights of subrogation and reimbursement against Borrower by
operation of Section 580d of the California Code of Civil Procedure or
otherwise.

Guarantor waives all rights and defenses that Guarantor may have because
Borrower's obligation is secured by real property.  This means among other
things: (1) Lender may collect from Guarantor without first foreclosing on any
real or personal property collateral pledged by Borrower. (2) If Lender
forecloses on any real property collateral pledged by Borrower: (A) The amount
of Borrower's obligation may be reduced only by the price for which the
collateral is sold at the foreclosure sale, even it the collateral is worth more
than the sale price. (B) Lender may collect from Guarantor even if Lender, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from Borrower.  This is an unconditional waiver of any
rights and defenses Guarantor may have because Borrower's obligation is secured
by real property.  These rights and defenses include, but are not limited to,
any rights and defenses based upon Section 580a, 580b, 580d, or 726 of the Code
of Civil Procedure.

Guarantor understands and agrees that the foregoing waivers are waivers of
substantive rights and defenses to which Guarantor might otherwise be entitled
under state and federal law.  The rights and defenses waived include, without
limitation, those provided by California laws of suretyship and guaranty, anti-
deficiency laws, and the Uniform Commercial Code.  Guarantor acknowledges that
Guarantor has provided these waivers of rights and defenses with the intention
that they be fully relied upon by Lender.  Until all Indebtedness is paid in
full, Guarantor waives any right to enforce any remedy Lender may have against
Borrower or any other guarantor, surety, or other person, and further, Guarantor
waives any right to participate in any collateral for the Indebtedness now or
hereafter held by Lender.

If now or hereafter (a) Borrower shall be or become insolvent, and (b) the
Indebtedness shall not at all times until paid be fully secured by collateral
pledged by Borrower, Guarantor hereby forever waives and relinquishes in favor
of Lender and Borrower, and their respective successors, any claim or right to
payment Guarantor may now have or hereafter have or acquire against Borrower, by
subrogation or otherwise, so that at no time shall Guarantor be or become a
"creditor" of Borrower within the meaning of 11 U.S.C. section 547(b), or any
successor provision of the Federal bankruptcy laws.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS.  Guarantor warrants and
agrees that each of the waivers set forth above is made with Guarantor's full
knowledge of its significance and consequences and that, under the
circumstances, the waivers are reasonable and not contrary to public policy or
law.  If any such waiver is determined to be contrary to any applicable law or
public policy, such waiver shall be effective only to the extent permitted by
law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR.  Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter created,
shall be prior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent.  Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower.  In the event of insolvency and consequent liquidation of the assets
of Borrower, through bankruptcy, by an assignment for the benefit of creditors,
by voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims of both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that such assignment shall be

================================================================================

effective only for the purpose of assuring to Lender full payment in legal
tender of the Indebtedness. If Lender so requests, any notes or credit
agreements now or hereafter evidencing any debts or obligations of Borrower to
Guarantor shall be marked with a legend that the same are subject to this
Guaranty and shall be delivered to Lender. Guarantor agrees, and Lender hereby
is authorized, in the name of Guarantor, from time to time to execute and file
financing statements and continuation statements and to execute such other
documents and to take such other actions as Lender deems necessary or
appropriate to perfect, preserve and enforce its rights under this Guaranty.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Guaranty:

     INTEGRATION, AMENDMENT. Guarantor warrants, represents and agrees that this
     Guaranty, together with any exhibits or schedules incorporated herein,
     fully incorporates the agreements and understandings of Guarantor with
     Lender with respect to the subject matter hereof and all prior
     negotiations, drafts, and other extrinsic communications between Guarantor
     and Lender shall have no evidentiary effect whatsoever. Guarantor further
     agrees that Guarantor has read and fully understands the terms of this
     Guaranty; Guarantor has had the opportunity to be advised by Guarantor's
     attorney with respect to this Guaranty; the Guaranty fully reflects
     Guarantor's intentions and parol evidence is not required to interpret the
     terms of this Guaranty. Guarantor hereby indemnifies and holds Lender
     harmless from all losses, claims, damages, and costs (including Lender's
     attorneys' fees) suffered or incurred by Lender as a result of any breach
     by Guarantor of the warranties, representations and agreements of this
     paragraph. No alteration or amendment to this Guaranty shall be effective
     unless given in writing and signed by the parties sought to be charged or
     bound by the alteration or amendment.

     APPLICABLE LAW. This Guaranty has been delivered to Lender and accepted by
     Lender in the State of California. If there is a lawsuit, Guarantor agrees
     upon Lender's request to submit to the jurisdiction of the courts of MARIN
     County, State of California. Lender and Guarantor hereby waive the right to
     any jury trial in any action, proceeding, or counterclaim brought by either
     Lender or Guarantor against the other. This Guaranty shall be governed by
     and construed in accordance with the laws of the State of California.

     ATTORNEYS' FEES; EXPENSES. Guarantor agrees to pay upon demand all of
     Lender's costs and expenses, including attorneys' fees and Lender's legal
     expenses, incurred in connection with the enforcement of this Guaranty.
     Lender may pay someone else to help enforce this Guaranty, and Guarantor
     shall pay the costs and expenses of such enforcement. Costs and expenses
     include Lender's attorneys' fees and legal expenses whether or not there is
     a lawsuit, including attorneys' fees and legal expenses for bankruptcy
     proceedings (and including efforts to modify or vacate any automatic stay
     or injunction), appeals, and any anticipated post-judgment collection
     services. Guarantor also shall pay all court costs and such additional fees
     as may be directed by the court.

     NOTICES. All notices required to be given by either party to the other
     under this Guaranty shall be in writing, may be sent by telefacsimile, and,
     except for revocation notices by Guarantor, shall be effective when
     actually delivered or when deposited with a nationally recognized overnight
     courier, or when deposited in the United States mail, first class postage
     prepaid, addressed to the party to whom the notice is to be given at the
     address shown above or to such other addresses as either party may
     designate to the other in writing. All revocation notices by Guarantor
     shall be in writing and shall be effective only upon delivery to Lender as
     provided above in the section titled "DURATION OF GUARANTY." If there is
     more than one Guarantor, notice to any Guarantor will constitute notice to
     all Guarantors. For notice purposes, Guarantor agrees to keep Lender
     informed at all times of Guarantor's current address.

     INTERPRETATION. In all cases where there is more than one Borrower or
     Guarantor, then all words used in this Guaranty in the singular shall be
     deemed to have been used in the plural where the context and construction
     so require; and where there is more than one Borrower named in this
     Guaranty or when this Guaranty is executed by more than one Guarantor, the
     words "Borrower" and "Guarantor" respectively shall mean all and any one or
     more of them. The words "Guarantor," "Borrower," and "Lender" include the
     heirs, successors,

     assigns, and transferees of each of them. Caption headings in this Guaranty
     are for convenience purposes only and are not to be used to interpret or
     define the provisions of this Guaranty. If a court of competent
     jurisdiction finds any provision of this Guaranty to be invalid or
     unenforceable as to any person or circumstance, such finding shall not
     render that provision invalid or unenforceable as to any other persons or
     circumstances, and all provisions of this Guaranty in all other respects
     shall remain valid and enforceable. If any one or more of Borrower or
     Guarantor are corporations or partnerships, it is not necessary for Lender
     to inquire into the powers of Borrower or Guarantor or of the officers,
     directors, partners, or agents acting or purporting to act on their behalf,
     and any Indebtedness made or created in reliance upon the professed
     exercise of such powers shall be guaranteed under this Guaranty.

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Guaranty unless such waiver is given in writing and signed by Lender. No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender of
     a provision of this Guaranty shall not prejudice or constitute a waiver of
     Lender's right otherwise to demand strict compliance with that provision or
     any other provision of this Guaranty. No prior waiver by Lender, nor any
     course of dealing between Lender and Guarantor, shall constitute a waiver
     of any of Lender's rights or of any of Guarantor's obligations as to any
     future transactions. Whenever the consent of Lender is required under this
     Guaranty, the granting of such consent by Lender in any instance shall not
     constitute continuing consent to subsequent instances where such consent is
     required and in all cases such consent may be granted or withheld in the
     sole discretion of Lender.

EACH UNDERSIGNED GUARANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS
GUARANTY AND AGREES TO ITS TERMS.  IN ADDITION, EACH GUARANTOR UNDERSTANDS THAT
THIS GUARANTY IS EFFECTIVE UPON GUARANTOR'S EXECUTION AND DELIVERY OF THIS
GUARANTY TO LENDER AND THAT THE GUARANTY WILL CONTINUE UNTIL TERMINATED IN THE
MANNER SET FORTH IN THE SECTION TITLED "DURATION OF GUARANTY." NO FORMAL
ACCEPTANCE BY LENDER IS NECESSARY TO MAKE THIS GUARANTY EFFECTIVE.  THIS
GUARANTY IS DATED MARCH 13,1997.

     BORROWER.  The word "Borrower" means TIER TECHNOLOGIES, INC..

     GUARANTOR.  The word "Guarantor" means JAMES L. BILDNER.

     GUARANTY. The word "Guaranty" means this Guaranty made by Guarantor for the

     unliquidated, determined or undetermined; whether Borrower may be liable
     individually or jointly with others, or primarily or secondarily, or as
     guarantor or surety; whether recovery on the Indebtedness may be or may
     become barred or unenforceable against Borrower for any reason whatsoever;
     and whether the Indebtedness arises from transactions which may be voidable
     on account of infancy, insanity, ultra vires, or otherwise.

     LENDER.  The word "Lender" means WESTAMERICA BANK, its successors and
     assigns.

     RELATED DOCUMENTS. The words "Related Documents" mean and include without
     limitation all promissory notes, credit agreements, loan agreements,

FEES INCURRED IN CONNECTION WITH OR RELATING TO (A) THE COLLECTION OF THE

LOAN NO 704-00488                      (CONTINUED)

================================================================================

ATTORNEYS' FEES INCLUDE, WITHOUT LIMITATION, ATTORNEYS' FEES WHETHER OR NOT
THERE IS A LAWSUIT, AND IF THERE IS A LAWSUIT, ANY FEES AND COSTS FOR TRIAL AND
APPEALS.

The above limitation on liability is not a restriction on the amount of the
Indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative.  This Guaranty shall not (unless specifically provided
below to the contrary) affect or invalidate any such other guaranties.  The
liability of Guarantor will be the aggregate liability of Guarantor under the
terms of this Guaranty and any such other unterminated guaranties.

NATURE OF GUARANTY.  Guarantor's liability under this Guaranty shall be open and
continuous for so long as this Guaranty remains in force.  Guarantor intends to
guarantee at all times the performance and prompt payment when due, whether at
maturity or earlier by reason of acceleration or otherwise, of all Indebtedness
within the limits set forth in the preceding section of this Guaranty.
Accordingly, no payments made upon the Indebtedness will discharge or diminish
the continuing liability of Guarantor in connection with any remaining portions
of the Indebtedness or any of the Indebtedness which subsequently arises or is
thereafter incurred or contracted.  Any married person who signs this Guaranty
hereby expressly agrees that recourse may be had against both his or her
separate property and community property.

DURATION OF GUARANTY.  This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by Lender of any notice of revocation shall have been
fully and finally paid and satisfied and all other obligations of Guarantor
under this Guaranty shall have been performed in full.  If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing.  Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at the address
of Lender listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by Lender of Guarantor's written
revocation.  For this purpose and without limitation, the term "new
Indebtedness" does not include Indebtedness which at the time of notice of
revocation is contingent, unliquidated, undetermined or not due and which later
becomes absolute, liquidated, determined or due.  This Guaranty will continue to
bind Guarantor for all Indebtedness incurred by Borrower or committed by Lender
prior to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness.  All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness.  This Guaranty shall
bind the estate of Guarantor as to Indebtedness created both before and after
the death or incapacity of Guarantor, regardless of Lender's actual notice of
Guarantor's death.  Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect.  Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty, A revocation received by Lender from any one or more Guarantors shall
not affect the liability of any remaining Guarantors under this Guaranty.  IT IS
ANTICIPATED THAT FLUCTUATIONS MAY OCCUR IN THE AGGREGATE AMOUNT OF INDEBTEDNESS
COVERED BY THIS GUARANTY, AND IT IS SPECIFICALLY ACKNOWLEDGED AND AGREED BY
GUARANTOR THAT REDUCTIONS IN THE AMOUNT OF INDEBTEDNESS, EVEN TO ZERO DOLLARS
($0.00), PRIOR TO WRITTEN REVOCATION OF THIS GUARANTY BY GUARANTOR SHALL NOT
CONSTITUTE A TERMINATION OF THIS GUARANTY.  THIS GUARANTY IS BINDING UPON
GUARANTOR AND GUARANTOR'S HEIRS, SUCCESSORS AND ASSIGNS SO LONG AS ANY OF THE
GUARANTEED INDEBTEDNESS REMAINS UNPAID AND EVEN THOUGH THE INDEBTEDNESS
GUARANTEED MAY FROM TIME TO TIME BE ZERO DOLLARS ($0.00).

GUARANTOR'S AUTHORIZATION TO LENDER.  Guarantor authorizes Lender, either before
or after any revocation hereof, WITHOUT NOTICE OR DEMAND AND WITHOUT LESSENING
GUARANTOR'S LIABILITY UNDER THIS GUARANTY, FROM TIME TO TIME: (A) PRIOR TO
REVOCATION AS SET FORTH ABOVE, TO MAKE ONE OR MORE ADDITIONAL SECURED OR
UNSECURED LOANS TO BORROWER, TO LEASE EQUIPMENT OR OTHER GOODS TO BORROWER, OR
OTHERWISE TO EXTEND ADDITIONAL CREDIT TO BORROWER; (B) TO ALTER, COMPROMISE,
RENEW, EXTEND, ACCELERATE, OR OTHERWISE CHANGE ONE OR MORE TIMES THE TIME FOR
PAYMENT OR OTHER TERMS OF THE INDEBTEDNESS OR ANY PART OF THE INDEBTEDNESS,
INCLUDING INCREASES AND DECREASES OF THE RATE OF

to Lender that (a) no representations or agreements of any kind have been made
to Guarantor which would limit or qualify in any way the terms of this Guaranty;
(b) this Guaranty is executed at Borrower's request and not at the request of
Lender; (c) Guarantor has full power, right and authority to enter into this

written consent of Lender, sell, lease, assign, encumber, hypothecate, transfer,
or otherwise dispose of all or substantially all of Guarantor's assets, or any

financial and credit information in form acceptable to Lender, and all such

information which will be provided to Lender is and will be true and correct in
all material respects and fairly present the financial condition of Guarantor as
of the dates the financial information is provided; (g) no material adverse
change has occurred in Guarantor's financial condition since the date of the
most recent financial statements provided to Lender and no event has occurred
which may materially adversely affect Guarantor's financial condition; (h) no
litigation, claim, investigation, administrative proceeding or similar action
(including those for unpaid taxes) against Guarantor is pending or threatened;
(i) Lender has made no representation to Guarantor as to the creditworthiness of
Borrower; and (j) Guarantor has established adequate means of obtaining from
Borrower on a continuing basis information regarding Borrower's financial
condition.  Guarantor agrees to keep adequately informed from such means of any
facts, events, or circumstances which might in any way affect Guarantor's risks
under this Guaranty, and Guarantor further agrees that, absent a request for
information, Lender shall have no obligation to disclose to Guarantor any
information or documents acquired by Lender in the course of its relationship
with Borrower.

GUARANTOR'S WAIVERS.  Except as prohibited by applicable law, Guarantor waives
any right to require Lender to (a) make any presentment, protest, demand, or
notice of any kind, including notice of change of any terms of repayment of the
Indebtedness, default by Borrower or any other guarantor or surety, any action
or nonaction taken by Borrower, Lender, or any other guarantor or surety of
Borrower, or the creation of new or additional Indebtedness; (b) proceed against
any person, including Borrower, before proceeding against Guarantor; (c) proceed
against any collateral for the Indebtedness, including Borrower's collateral,
before proceeding against Guarantor; (d) apply any payments or proceeds received
against the Indebtedness in any order; (e) give notice of the terms, time, and
place of any sale of the collateral pursuant to the Uniform Commercial Code or
any other law governing such sale; (f) disclose any information about the
Indebtedness, the Borrower, the collateral, or any other guarantor or surety, or
about any action or nonaction of Lender; or (g) pursue any remedy or course of
action in Lender's power whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (h)
any disability or other defense of Borrower, any other guarantor or surety or
any other person; (i) the cessation from any cause whatsoever, other than
payment in full, of the Indebtedness; (j) the application of proceeds of the
Indebtedness by Borrower for purposes other than the purposes understood and
intended by Guarantor and Lender; (k) any act of omission or commission by
Lender which directly or indirectly results in or contributes to the discharge
of Borrower or any other guarantor or surety, or the Indebtedness, or the loss
or release of any collateral by operation of law or otherwise; (l) any statute
of limitations in any action under this Guaranty or on the Indebtedness; or (m)

extension, acceleration, or other change in the time payment of the Indebtedness
is due and any change in the interest rate, and including any such modification
or change in terms after revocation of this Guaranty on Indebtedness incurred
prior to such revocation.

Guarantor waives all rights and any defenses arising out of an election of
remedies by Lender even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for a guaranteed obligation, has destroyed
Guarantor's rights of subrogation and reimbursement against Borrower by
operation of Section 580d of the California Code of Civil Procedure or
otherwise.

Guarantor waives all rights and defenses that Guarantor may have because
Borrower's obligation is secured by real property.  This means among other
things: (1) Lender may collect from Guarantor without first foreclosing on any
real or personal property collateral pledged by Borrower. (2) If Lender
forecloses on any real property collateral pledged by Borrower: (A) The amount
of Borrower's obligation may be reduced only by the price for which the
collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price. (B) Lender may collect from Guarantor even if Lender, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from Borrower.  This is an unconditional waiver of any
rights and defenses Guarantor may have because Borrower's obligation is secured
by real property.  These rights and defenses include, but are not limited to,
any rights and defenses based upon Section 580a, 580b, 580d, or 726 of the Code
of Civil Procedure.

Guarantor understands and agrees that the foregoing waivers are waivers of
substantive rights and defenses to which Guarantor might otherwise be entitled
under state and federal law.  The rights and defenses waived include, without
limitation, those provided by California laws of suretyship and guaranty, anti-
deficiency laws, and the Uniform Commercial Code.  Guarantor acknowledges that
Guarantor has provided these waivers of rights and defenses with the intention
that they be fully relied upon by Lender.  Until all Indebtedness is paid in
full, Guarantor waives any right to enforce any remedy Lender may have against
Borrower or any other guarantor, surety, or other person, and further, Guarantor
waives any right to participate in any collateral for the Indebtedness now or
hereafter held by Lender.

If now or hereafter (a) Borrower shall be or become insolvent, and (b) the
Indebtedness shall not at all times until paid be fully secured by collateral
pledged by Borrower, Guarantor hereby forever waives and relinquishes in favor
of Lender and Borrower, and their respective successors, any claim or right to
payment Guarantor may now have or hereafter have or acquire against Borrower, by
subrogation or otherwise, so that at no time shall Guarantor be or become a
"creditor" of Borrower within the meaning of 11 U.S.C. section 547(b), or any
successor provision of the Federal bankruptcy laws.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS.  Guarantor warrants and
agrees that each of the waivers set forth above is made with Guarantor's full
knowledge of its significance and consequences and that, under the
circumstances, the waivers are reasonable and not contrary to public policy or
law.  If any such waiver is determined to be contrary to any applicable law or
public policy, such waiver shall be effective only to the extent permitted by
law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR.  Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter created,
shall be prior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent.  Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower.  In the event of insolvency and consequent liquidation of the assets
of Borrower, through bankruptcy, by an assignment for the benefit of creditors,
by voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims of both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the Indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that such assignment shall be effective only for the purpose
of assuring to Lender full payment in legal tender of the Indebtedness.  If
Lender so requests, any notes or credit agreements now or hereafter evidencing
any debts or obligations of Borrower to

appropriate to perfect, preserve and enforce its rights under this Guaranty.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Guaranty:

   INTEGRATION, AMENDMENT.  Guarantor warrants, represents and agrees that this
   Guaranty, together with any exhibits or schedules incorporated herein, fully
   incorporates the agreements and understandings of Guarantor with Lender with
   respect to the subject matter hereof and all prior negotiations, drafts, and
   other extrinsic communications between Guarantor and Lender shall have no
   evidentiary effect whatsoever.  Guarantor further agrees that Guarantor has
   read and fully understands the terms of this Guaranty; Guarantor has had the
   opportunity to be advised by Guarantor's attorney with respect to this
   Guaranty; the Guaranty fully reflects Guarantor's intentions and parol
   evidence is not required to interpret the terms of this Guaranty.  Guarantor
   hereby indemnities and holds Lender harmless from all losses, claims,
   damages, and costs (including Lender's attorneys' fees) suffered or incurred
   by Lender as a result of any breach by Guarantor of the warranties,
   representations and agreements of this paragraph.  No alteration or amendment
   to this Guaranty shall be effective unless given in writing and signed by the
   parties sought to be charged or bound by the alteration or amendment.

   APPLICABLE LAW.  This Guaranty has been delivered to Lender and accepted by
   Lender in the State of California.  It there is a lawsuit, Guarantor agrees
   upon Lender's request to submit to the jurisdiction of the courts of MARIN
   County, State of California.  Lender and Guarantor hereby waive the right to
   any jury trial in any action, proceeding, or counterclaim brought by either
   Lender or Guarantor against the other.  This Guaranty shall be governed by
   and construed in accordance with the laws of the State of California.

   ATTORNEYS' FEES; EXPENSES.  Guarantor agrees to pay upon demand all of
   Lender's costs and expenses, including attorneys' fees and Lender's legal
   expenses, incurred in connection with the enforcement of this Guaranty.
   Lender may pay someone else to help enforce this Guaranty, and Guarantor
   shall pay the costs and expenses of such enforcement.  Costs and expenses
   include Lender's attorneys' fees and legal expenses whether or not there is a
   lawsuit, including attorneys' fees and legal expenses for bankruptcy
   proceedings (and including efforts to modify or vacate any automatic stay or
   injunction), appeals, and any anticipated post-judgment collection services.
   Guarantor also shall pay all court costs and such additional fees as may be
   directed by the court.

   NOTICES.  All notices required to be given by either party to the other under
   this Guaranty shall be in writing, may be sent by telefacsimile, and, except
   for revocation notices by Guarantor, shall be effective when actually
   delivered or when deposited with a nationally recognized overnight courier,
   or when deposited in the United States mail, first class postage prepaid,
   addressed to the party to whom the notice is to be given at the address shown
   above or to such other addresses as either party may designate to the other
   in writing.  All revocation notices by Guarantor shall be in writing and
   shall be effective only upon delivery to Lender as provided above in the
   section titled "DURATION OF GUARANTY." If there is more than one Guarantor,
   notice to any Guarantor will constitute notice to all Guarantors.  For notice
   purposes, Guarantor agrees to keep Lender informed at all times of
   Guarantor's current address.

   INTERPRETATION.  In all cases where there is more than one Borrower or
   Guarantor, then all words used in this Guaranty in the singular shall be
   deemed to have been used in the plural where the context and construction so
   require; and where there is more than one Borrower named in this Guaranty or
   when this Guaranty is executed by more than one Guarantor, the words
   "Borrower' and "Guarantor" respectively shall mean all and any one or more of
   them.  The words "Guarantor," "Borrower," and "Lender" include the heirs,
   successors, assigns, and transferees of each of them.  Caption headings in
   this Guaranty are for convenience purposes only and are not to be used to
   interpret or define the provisions of this Guaranty.  If a court of competent

================================================================================

   jurisdiction finds any provision of this Guaranty to be invalid or
   unenforceable as to any person or circumstance, such finding shall not render
   that provision invalid or unenforceable as to any other persons or
   circumstances, and all provisions of this Guaranty in all other respects
   shall remain valid and enforceable.  If any one or more of Borrower or
   Guarantor are corporations or partnerships, it is not necessary for Lender to
   inquire into the powers of Borrower or Guarantor or of the officers,
   directors, partners, or agents acting or purporting to act on their behalf,
   and any Indebtedness made or created in reliance upon the professed exercise
   of such powers shall be guaranteed under this Guaranty.

   WAIVER.  Lender shall not be deemed to have waived any rights under this
   Guaranty unless such waiver is given in writing and signed by Lender.  No
   delay or omission on the part of Lender in exercising any right shall operate
   as a waiver of such right or any other right.  A waiver by Lender of a
   provision of this Guaranty shall not prejudice or constitute a waiver of
   Lender's right otherwise to demand strict compliance with that provision or
   any other provision of this Guaranty.  No prior waiver by Lender, nor any
   course of dealing between Lender and Guarantor, shall constitute a waiver of
   any of Lender's rights or of any of Guarantor's obligations as to any future
   transactions.  Whenever the consent of Lender is required under this
   Guaranty, the granting of such consent by Lender in any instance shall not
   constitute continuing consent to subsequent instances where such consent is
   required and in all cases such consent may be granted or withheld in the sole
   discretion of Lender.

EACH UNDERSIGNED GUARANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS
GUARANTY AND AGREES TO ITS TERMS.  IN ADDITION, EACH GUARANTOR UNDERSTANDS THAT
THIS GUARANTY IS EFFECTIVE UPON GUARANTOR'S EXECUTION AND DELIVERY OF THIS
GUARANTY TO LENDER AND THAT THE GUARANTY WILL CONTINUE UNTIL TERMINATED IN THE
MANNER SET FORTH IN THE SECTION TITLED "DURATION OF GUARANTY." NO FORMAL
ACCEPTANCE BY LENDER IS NECESSARY TO MAKE THIS GUARANTY EFFECTIVE.  THIS
GUARANTY IS DATED MARCH 13,1997.

03-13-1997                      COMMERCIAL GUARANTY
LOAN NO 704-00488                   (CONTINUED)

================================================================================

The above limitation on liability is not a restriction on the amount of the
Indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative.  This Guaranty shall not (unless specifically provided
below to the contrary) affect or invalidate any such other guaranties.  The
liability of Guarantor will be the aggregate liability of Guarantor under the
terms of this Guaranty and any such other unterminated guaranties.

NATURE OF GUARANTY.  Guarantor's liability under this Guaranty shall be open and
continuous for so long as this Guaranty remains in force.  Guarantor intends to
guarantee at all times the performance and prompt payment when due, whether at
maturity or earlier by reason of acceleration or otherwise, of all Indebtedness
within the limits set forth in the preceding section of this Guaranty.
Accordingly, no payments made upon the Indebtedness will discharge or diminish
the continuing liability of Guarantor in connection with any remaining portions
of the Indebtedness or any of the Indebtedness which subsequently arises or is
thereafter incurred or contracted.  Any married person who signs this Guaranty
hereby expressly agrees that recourse may be had against both his or her
separate property and community property.

DURATION OF GUARANTY.  This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by Lender of any notice of revocation shall have been
fully and finally paid and satisfied and all other obligations of Guarantor
under this Guaranty shall have been performed in full.  If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing.  Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at the address
of Lender listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by Lender of Guarantor's written
revocation.  For this purpose and without limitation, the term "new
Indebtedness" does not include Indebtedness which at the time of notice of
revocation is contingent, unliquidated, undetermined or not due and which later
becomes absolute, liquidated, determined or due.  This Guaranty will continue to
bind Guarantor for all Indebtedness incurred by Borrower or committed by Lender
prior to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness.  All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness.  This Guaranty shall
bind the estate of Guarantor as to Indebtedness created both before and after
the death or incapacity of Guarantor, regardless of Lender's actual notice of
Guarantor's death.  Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect.  Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty.  A revocation received by Lender from any one or more Guarantors shall
not affect the liability of any remaining Guarantors under this Guaranty.  IT IS
ANTICIPATED THAT FLUCTUATIONS MAY OCCUR IN THE AGGREGATE AMOUNT OF INDEBTEDNESS
COVERED BY THIS GUARANTY, AND IT IS SPECIFICALLY ACKNOWLEDGED AND AGREED BY
GUARANTOR THAT REDUCTIONS IN THE AMOUNT OF INDEBTEDNESS, EVEN TO ZERO DOLLARS
($0.00), PRIOR TO WRITTEN REVOCATION OF THIS GUARANTY BY GUARANTOR SHALL NOT
CONSTITUTE A TERMINATION OF THIS GUARANTY.  THIS GUARANTY IS BINDING UPON
GUARANTOR AND GUARANTOR'S HEIRS, SUCCESSORS AND ASSIGNS SO LONG AS ANY OF THE
GUARANTEED INDEBTEDNESS REMAINS UNPAID AND EVEN THOUGH THE INDEBTEDNESS
GUARANTEED MAY FROM TIME TO TIME BE ZERO DOLLARS ($0.00).

GUARANTOR'S AUTHORIZATION TO LENDER.  Guarantor authorizes Lender, either before
or after any revocation hereof, WITHOUT NOTICE OR DEMAND AND WITHOUT LESSENING
GUARANTOR'S LIABILITY UNDER THIS GUARANTY, FROM TIME TO TIME: (A) PRIOR TO
REVOCATION AS SET FORTH ABOVE, TO MAKE ONE OR MORE ADDITIONAL SECURED OR
UNSECURED LOANS TO BORROWER, TO LEASE EQUIPMENT OR OTHER GOODS TO BORROWER, OR
OTHERWISE TO EXTEND ADDITIONAL CREDIT TO BORROWER; (B) TO ALTER, COMPROMISE,
RENEW, EXTEND, ACCELERATE, OR OTHERWISE CHANGE ONE OR MORE TIMES THE TIME FOR
PAYMENT OR OTHER TERMS OF THE INDEBTEDNESS OR ANY PART OF THE INDEBTEDNESS,
INCLUDING INCREASES AND DECREASES OF THE RATE OF INTEREST ON THE INDEBTEDNESS;
EXTENSIONS MAY BE REPEATED AND MAY BE FOR LONGER THAN THE ORIGINAL LOAN TERM;
(C) TO TAKE AND HOLD SECURITY FOR THE PAYMENT OF THIS GUARANTY OR THE
INDEBTEDNESS, AND EXCHANGE, ENFORCE, WAIVE,

to Lender that (a) no representations or agreements of any kind have been made
to Guarantor which would limit or qualify in any way the terms of this Guaranty;
(b) this Guaranty is executed at Borrower's request and not at the request of
Lender; (c) Guarantor has full power, right and authority to enter into this

written consent of Lender, sell, lease, assign, encumber, hypothecate, transfer,

financial and credit information in form acceptable to Lender, and all such

all material respects and fairly present the financial condition of Guarantor as
of the dates the financial information is provided; (g) no material adverse
change has occurred in Guarantor's financial condition since the date of the
most recent financial statements provided to Lender and no event has occurred
which may materially adversely affect Guarantor's financial condition; (h) no
litigation, claim, investigation, administrative proceeding or similar action
(including those for unpaid taxes) against Guarantor is pending or threatened;
(i) Lender has made no representation to Guarantor as to the creditworthiness of
Borrower; and (j) Guarantor has established adequate means of obtaining from
Borrower on a continuing basis information regarding Borrower's financial
condition.  Guarantor agrees to keep adequately informed from such means of any
facts, events, or circumstances which might in any way affect Guarantor's risks
under this Guaranty, and Guarantor further agrees that, absent a request for
information, Lender shall have no obligation to disclose to Guarantor any
information or documents acquired by Lender in the course of its relationship
with Borrower,

GUARANTOR'S WAIVERS.  Except as prohibited by applicable law, Guarantor waives
any right to require Lender to (a) make any presentment, protest, demand, or
notice of any kind, including notice of change of any terms of repayment of the
Indebtedness, default by Borrower or any other guarantor or surety, any action
or nonaction taken by Borrower, Lender, or any other guarantor or surety of
Borrower, or the creation of new or additional Indebtedness; (b) proceed against
any person, including Borrower, before proceeding against Guarantor; (c) proceed
against any collateral for the Indebtedness, including Borrower's collateral,
before proceeding against Guarantor; (d) apply any payments or proceeds received
against the Indebtedness in any order; (e) give notice of the terms, time, and
place of any sale of the collateral pursuant to the Uniform Commercial Code or
any other law governing such sale; (f) disclose any information about the
Indebtedness, the Borrower, the collateral, or any other guarantor or surety, or
about any action or nonaction of Lender; or (g) pursue any remedy or course of
action in Lender's power whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (h)
any disability or other defense of Borrower, any other guarantor or surety or
any other person; (i) the cessation from any cause whatsoever, other than
payment in full, of the Indebtedness; (j) the application of proceeds of the
Indebtedness by Borrower for purposes other than the purposes understood and
intended by Guarantor and Lender; (k) any act of omission or commission by
Lender which directly or indirectly results in or contributes to the discharge
of Borrower or any other guarantor or surety, or the Indebtedness, or the loss
or release of any collateral by operation of law or otherwise; (l) any statute
of limitations in any action under this Guaranty or on the Indebtedness; or (m)

================================================================================

interest rate, and including any such modification or change in terms after
revocation of this Guaranty on Indebtedness incurred prior to such revocation.

Guarantor waives all rights and any defenses arising out of an election of
remedies by Lender even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for a guaranteed obligation, has destroyed
Guarantor's rights of subrogation and reimbursement against Borrower by
operation of Section 580d of the California Code of Civil Procedure or
otherwise.

Guarantor waives all rights and defenses that Guarantor may have because
Borrower's obligation is secured by real property.  This means among other
things: (1) Lender may collect from Guarantor without first foreclosing on any
real or personal property collateral pledged by Borrower. (2) If Lender
forecloses on any real property collateral pledged by Borrower: (A) The amount
of Borrower's obligation may be reduced only by the price for which the
collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price. (B) Lender may collect from Guarantor even if Lender, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from Borrower.  This is an unconditional waiver of any
rights and defenses Guarantor may have because Borrower's obligation is secured
by real property.  These rights and defenses include, but are not limited to,
any rights and defenses based upon Section 580a, 580b, 580d, or 726 of the Code
of Civil Procedure.

Guarantor understands and agrees that the foregoing waivers are waivers of
substantive rights and defenses to which Guarantor might otherwise be entitled
under state and federal law.  The rights and defenses waived include, without
limitation, those provided by California laws of suretyship and guaranty, anti-
deficiency laws, and the Uniform Commercial Code.  Guarantor acknowledges that
Guarantor has provided these waivers of rights and defenses with the intention
that they be fully relied upon by Lender.  Until all Indebtedness is paid in
full, Guarantor waives any right to enforce any remedy Lender may have against
Borrower or any other guarantor, surety, or other person, and further, Guarantor
waives any right to participate in any collateral for the Indebtedness now or
hereafter held by Lender.

If now or hereafter (a) Borrower shall be or become insolvent, and (b) the
Indebtedness shall not at all times until paid be fully secured by collateral
pledged by Borrower, Guarantor hereby forever waives and relinquishes in favor
of Lender and Borrower, and their respective successors, any claim or right to
payment Guarantor may now have or hereafter have or acquire against Borrower, by
subrogation or otherwise, so that at no time shall Guarantor be or become a
"creditor" of Borrower within the meaning of 11 U.S.C. section 547(b), or any
successor provision of the Federal bankruptcy laws.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS.  Guarantor warrants and
agrees that each of the waivers set forth above is made with Guarantor's full
knowledge of its significance and consequences and that, under the
circumstances, the waivers are reasonable and not contrary to public policy or
law.  If any such waiver is determined to be contrary to any applicable law or
public policy, such waiver shall be effective only to the extent permitted by
law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR.  Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter created,
shall be prior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent.  Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower.  In the event of insolvency and consequent liquidation of the assets
of Borrower, through bankruptcy, by an assignment for the benefit of creditors,
by voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims of both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the Indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that such assignment shall be effective only for the purpose
of assuring to Lender full payment in legal tender of the Indebtedness.  If
Lender so requests, any notes or credit agreements now or hereafter evidencing
any debts or obligations of Borrower to

Guarantor shall be marked with a legend that the same are subject to this

is authorized, in the name of Guarantor, from time to time to execute and file
financing statements and continuation statements and to execute such other
documents and to take such other actions as Lender deems necessary or
appropriate to perfect, preserve and enforce its rights under this Guaranty.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Guaranty:

   INTEGRATION, AMENDMENT.  Guarantor warrants, represents and agrees that this
   Guaranty, together with any exhibits or schedules incorporated herein, fully
   incorporates the agreements and understandings of Guarantor with Lender with
   respect to the subject matter hereof and all prior negotiations, drafts, and
   other extrinsic communications between Guarantor and Lender shall have no
   evidentiary effect whatsoever.  Guarantor further agrees that Guarantor has
   read and fully understands the terms of this Guaranty; Guarantor has had the
   opportunity to be advised by Guarantor's attorney with respect to this
   Guaranty; the Guaranty fully reflects Guarantor's intentions and parol
   evidence is not required to interpret the terms of this Guaranty.  Guarantor
   hereby indemnifies and holds Lender harmless from all losses, claims,
   damages, and costs (including Lender's attorneys' fees) suffered or incurred
   by Lender as a result of any breach by Guarantor of the warranties,
   representations and agreements of this paragraph.  No alteration or amendment
   to this Guaranty shall be effective unless given in writing and signed by the
   parties sought to be charged or bound by the alteration or amendment.

   APPLICABLE LAW.  This Guaranty has been delivered to Lender and accepted by
   Lender in the State of California.  If there is a lawsuit, Guarantor agrees
   upon Lender's request to submit to the jurisdiction of the courts of MARIN
   County, State of California.  Lender and Guarantor hereby waive the right to
   any jury trial in any action, proceeding, or counterclaim brought by either
   Lender or Guarantor against the other.  This Guaranty shall be governed by
   and construed in accordance with the laws of the State of California.

   ATTORNEYS' FEES; EXPENSES.  Guarantor agrees to pay upon demand all of
   Lender's costs and expenses, including attorneys' fees and Lender's legal
   expenses, incurred in connection with the enforcement of this Guaranty.
   Lender may pay someone else to help enforce this Guaranty, and Guarantor
   shall pay the costs and expenses of such enforcement.  Costs and expenses
   include Lender's attorneys' fees and legal expenses whether or not there is a
   lawsuit, including attorneys' fees and legal expenses for bankruptcy
   proceedings (and including efforts to modify or vacate any automatic stay or
   injunction), appeals, and any anticipated post-judgment collection services.
   Guarantor also shall pay all court costs and such additional fees as may be
   directed by the court.

   NOTICES.  All notices required to be given by either party to the other under
   this Guaranty shall be in writing, may be sent by telefacsimile, and, except
   for revocation notices by Guarantor, shall be effective when actually
   delivered or when deposited with a nationally recognized overnight courier,
   or when deposited in the United States mail, first class postage prepaid,
   addressed to the party to whom the notice is to be given at the address shown
   above or to such other addresses as either party may designate to the other
   in writing.  All revocation notices by Guarantor shall be in writing and
   shall be effective only upon delivery to Lender as provided above in the
   section titled "DURATION OF GUARANTY." If there is more than one Guarantor,
   notice to any Guarantor will constitute notice to all Guarantors.  For notice
   purposes, Guarantor agrees to keep Lender informed at all times of
   Guarantor's current address.

   INTERPRETATION.  In all cases where there is more than one Borrower or
   Guarantor, then all words used in this Guaranty in the singular shall be
   deemed to have been used in the plural where the context and construction so
   require; and where there is more than one Borrower named in this Guaranty or
   when this Guaranty is executed by more than one Guarantor, the words
   "Borrower" and "Guarantor" respectively shall mean all and any one or more of
   them.  The words "Guarantor," "Borrower," and "Lender" include the heirs,
   successors, assigns, and transferees of each of them.  Caption headings in
   this Guaranty are for convenience purposes only and are not to be used to
   interpret or define the provisions of this Guaranty.  If a court of competent

================================================================================

   jurisdiction finds any provision of this Guaranty to be invalid or
   unenforceable as to any person or circumstance, such finding shall not render
   that provision invalid or unenforceable as to any other persons or
   circumstances, and all provisions of this Guaranty in all other respects
   shall remain valid and enforceable.  If any one or more of Borrower or
   Guarantor are corporations or partnerships, it is not necessary for Lender to
   inquire into the powers of Borrower or Guarantor or of the officers,
   directors, partners, or agents acting or purporting to act, on their behalf,
   and any Indebtedness made or created in reliance upon the professed exercise
   of such powers shall be guaranteed under this Guaranty.

   WAIVER.  Lender shall not be deemed to have waived any rights under this
   Guaranty unless such waiver is given in writing and signed by Lender.  No
   delay or omission on the part of Lender in exercising any right shall operate
   as a waiver of such right or any other right.  A waiver by Lender of a
   provision of this Guaranty shall not prejudice or constitute a waiver of
   Lender's right otherwise to demand strict compliance with that provision or
   any other provision of this Guaranty.  No prior waiver by Lender, nor any
   course of dealing between Lender and Guarantor, shall constitute a waiver of
   any of Lender's rights or of any of Guarantor's obligations as to any future
   transactions.  Whenever the consent of Lender is required under this
   Guaranty, the granting of such consent by Lender in any instance shall not
   constitute continuing consent to subsequent instances where such consent is
   required and in all cases such consent may be granted or withheld in the sole
   discretion of Lender.

EACH UNDERSIGNED GUARANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS
GUARANTY AND AGREES TO ITS TERMS.  IN ADDITION, EACH GUARANTOR UNDERSTANDS THAT
THIS GUARANTY IS EFFECTIVE UPON GUARANTOR'S EXECUTION AND DELIVERY OF THIS
GUARANTY TO LENDER AND THAT THE GUARANTY WILL CONTINUE UNTIL TERMINATED IN THE
MANNER SET FORTH IN THE SECTION TITLED "DURATION OF GUARANTY." NO FORMAL
ACCEPTANCE BY LENDER IS NECESSARY TO MAKE THIS GUARANTY EFFECTIVE.  THIS
GUARANTY IS DATED MARCH 13,1997.

     refinancings of, consolidations of and substitutions for the note or credit
     agreement.

     RELATED DOCUMENTS.  The words "Related Documents" mean and include without
     limitation all promissory notes, credit agreements, loan agreements,
     environmental agreements, guaranties, security agreements, mortgages, deeds
     of trust, and all other instruments, agreements and documents, whether now
     or hereafter existing, executed in connection with the Indebtedness.

OBLIGATIONS OF GRANTOR.  Grantor warrants and covenants to Lender as follows:

  PERFECTION OF SECURITY INTEREST.  Grantor agrees to execute such financing
  statements and to take whatever other actions are requested by Lender to
  perfect and continue Lender's security interest in the Collateral.  Upon
  request of Lender, Grantor will deliver to Lender any and all of the documents
  evidencing or constituting the Collateral, and Grantor will note Lender's
  interest upon any and all chattel paper if not delivered to Lender for
  possession by Lender.  Grantor hereby appoints Lender as its irrevocable
  attorney-in-fact for the purpose of executing any documents necessary to
  perfect or to continue the security interest granted in this Agreement.
  Lender may at any time, and without further authorization from Grantor, file a
  carbon, photographic or other reproduction of any financing statement or of
  this Agreement for use as a financing statement.  Grantor will reimburse
  Lender for all expenses for the perfection and the continuation of the
  perfection of Lender's security interest in the Collateral.  Grantor promptly
  will notify Lender before any change in Grantor's name including any change to
  the assumed business names of Grantor.  THIS IS A CONTINUING SECURITY
  AGREEMENT AND WILL CONTINUE IN EFFECT EVEN THOUGH ALL OR ANY PART OF THE
  INDEBTEDNESS IS PAID IN FULL AND EVEN THOUGH FOR A PERIOD OF TIME GRANTOR MAY
  NOT BE INDEBTED TO LENDER.

  NO VIOLATION.  The execution and delivery of this Agreement will not violate
  any law or agreement governing Grantor or to which Grantor is a party, and its
  certificate or articles of incorporation and bylaws do not prohibit any term
  or condition of this Agreement.

  ENFORCEABILITY OF COLLATERAL.  To the extent the Collateral consists of
  accounts, chattel paper, or general intangibles, the Collateral is enforceable
  in accordance with its terms, is genuine, and complies with applicable laws
  concerning form, content and manner of preparation and execution, and all
  persons appearing to be obligated on the Collateral have authority and
  capacity to contract and are in fact obligated as they appear to be on the
  Collateral.  At the time any account becomes subject to a security interest in
  favor of Lender, the account shall be a good and valid account representing an
  undisputed, bona fide indebtedness incurred by the account debtor, for
  merchandise held subject to delivery instructions or theretofore shipped or
  delivered pursuant to a contract of sale, or for services theretofore
  performed by Grantor with or for the account debtor;

03-13-1997                 COMMERCIAL SECURITY AGREEMENT
LOAN NO 704-00488                   (CONTINUED)

================================================================================

  there shall be no setoffs or counterclaims against any such account; and no
  agreement under which any deductions or discounts may be claimed shall have
  been made with the account debtor except those disclosed to Lender in writing.

  LOCATION OF THE COLLATERAL.  Grantor, upon request of Lender, will deliver to
  Lender in form satisfactory to Lender a schedule of real properties and
  Collateral locations relating to Grantor's operations, including without
  limitation the following: (a) all real property owned or being purchased by
  Grantor; (b) all real property being rented or leased by Grantor; (c) all
  storage facilities owned, rented, leased, or being used by Grantor; and (d)
  all other properties where Collateral is or may be located.  Except in the
  ordinary course of its business, Grantor shall not remove the Collateral from
  its existing locations without the prior written consent of Lender.

  REMOVAL OF COLLATERAL.  Grantor shall keep the Collateral (or to the extent
  the Collateral consists of intangible property such as accounts, the records
  concerning the Collateral) at Grantor's address shown above, or at such other
  locations as are acceptable to Lender.  Except in the ordinary course of its
  business, including the sales of inventory, Grantor shall not remove the
  Collateral from its existing locations without the prior written consent of
  Lender.  To the extent that the Collateral consists of vehicles, or other
  titled property, Grantor shall not take or permit any action which would
  require application for certificates of title for the vehicles outside the
  State of California, without the prior written consent of Lender.

  TRANSACTIONS INVOLVING COLLATERAL.  Except for inventory sold or accounts
  collected in the ordinary course of Grantor's business, Grantor shall not
  sell, offer to sell, or otherwise transfer or dispose of the Collateral.
  While Grantor is not in default under this Agreement, Grantor may sell
  inventory, but only in the ordinary course of its business and only to buyers
  who qualify as a buyer in the ordinary course of business.  A sale in the
  ordinary course of Grantor's business does not include a transfer in partial
  or total satisfaction of a debt or any bulk sale.  Grantor shall not pledge,
  mortgage, encumber or otherwise permit the Collateral to be subject to any
  lien, security interest, encumbrance, or charge, other than the security
  interest provided for in this Agreement, without the prior written consent of
  Lender.  This includes security interests even if junior in right to the
  security interests granted under this Agreement.  Unless waived by Lender, all
  proceeds from any disposition of the Collateral (for whatever reason) shall be
  held in trust for Lender and shall not be commingled with any other funds;
  provided however, this requirement shall not constitute consent by Lender to
  any sale or other disposition.  Upon receipt, Grantor shall immediately
  deliver any such proceeds to Lender.

  TITLE.  Grantor represents and warrants to Lender that it holds good and
  marketable title to the Collateral, free and clear of all liens and
  encumbrances except for the lien of this Agreement.  No financing statement
  covering any of the Collateral is on file in any public office other than
  those which reflect the security interest created by this Agreement or to
  which Lender has specifically consented.  Grantor shall defend Lender's rights
  in the Collateral against the claims and demands of all other persons.

  COLLATERAL SCHEDULES AND LOCATIONS.  As often as Lender shall require, and
  insofar as the Collateral consists of accounts and general intangibles,
  Grantor shall deliver to Lender schedules of such Collateral, including such
  information as Lender may require, including without limitation names and
  addresses of account debtors and agings of accounts and general intangibles.
  Insofar as the Collateral consists of inventory and equipment, Grantor shall
  deliver to Lender, as often as Lender shall require, such lists, descriptions,
  and designations of such Collateral as Lender may require to identify the
  nature, extent, and location of such Collateral.  Such information shall be
  submitted for Grantor and each of its subsidiaries or related companies.

  MAINTENANCE AND INSPECTION OF COLLATERAL.  Grantor shall maintain all tangible
  Collateral in good condition and repair.  Grantor will not commit or permit
  damage to or destruction of the Collateral or any part of the Collateral.
  Lender and its designated representatives and agents shall have the right at
  all reasonable times to examine, inspect, and audit the Collateral wherever
  located.  Grantor shall immediately notify Lender of all cases involving the
  return, rejection, repossession, loss or damage of or to any Collateral; of
  any request for credit or adjustment or of any other dispute arising with
  respect to the Collateral; and generally of all happenings and events
  affecting the Collateral or the value or the amount of the Collateral.

LOAN NO 704-00488                   (CONTINUED)

================================================================================

  TAXES, ASSESSMENTS AND LIENS.  Grantor will pay when due all taxes,
  assessments and liens upon the Collateral, its use or operation, upon this
  Agreement, upon any promissory note or notes evidencing the Indebtedness, or
  upon any of the other Related Documents.  Grantor may withhold any such
  payment or may elect to contest any lien if Grantor is in good faith
  conducting an appropriate proceeding to contest the obligation to pay and so
  long as Lender's interest in the Collateral is not jeopardized in Lender's
  sole opinion.  If the Collateral is subjected to a lien which is not
  discharged within fifteen (15) days, Grantor shall deposit with Lender cash, a
  sufficient corporate surety bond or other security satisfactory to Lender in
  an amount adequate to provide for the discharge of the lien plus any interest,
  costs, attorneys' fees or other charges that could accrue as a result of
  foreclosure or sale of the Collateral.  In any contest Grantor shall defend
  itself and Lender and shall satisfy any final adverse judgment before
  enforcement against the Collateral.  Grantor shall name Lender as an
  additional obligee under any surety bond furnished in the contest proceedings.

  COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS.  Grantor shall comply promptly with
  all laws, ordinances, rules and regulations of all governmental authorities,
  now or hereafter in effect, applicable to the ownership, production,
  disposition, or use of the Collateral.  Grantor may contest in good faith any
  such law, ordinance or regulation and withhold compliance during any
  proceeding, including appropriate appeals, so long as Lender's interest in the
  Collateral, in Lender's opinion, is not jeopardized.

  HAZARDOUS SUBSTANCES.  Grantor represents and warrants that the Collateral
  never has been, and never will be so long as this Agreement remains a lien on
  the Collateral, used for the generation, manufacture, storage, transportation,
  treatment, disposal, release or threatened release of any hazardous waste or
  substance, as those terms are defined in the Comprehensive Environmental
  Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C.
  Section 9601, et seq. ("CERCLA"), the Superfund Amendments and Reauthorization
  Act of 1986, Pub.  L. No. 99-499 ("SARA"), the Hazardous Materials
  Transportation Act, 49 U.S.C. Section 1801, et seq., the Resource Conservation
  and Recovery Act, 42 U.S.C. Section 6901, et seq., Chapters 6.5 through 7.7 of
  Division 20 of the California Health and Safety Code, Section 25100, et seq.,
  or other applicable state or Federal laws, rules, or regulations adopted
  pursuant to any of the foregoing.  The terms "hazardous waste" and "hazardous
  substance" shall also include, without limitation, petroleum and petroleum by-
  products or any fraction thereof and asbestos.  The representations and
  warranties contained herein are based on Grantor's due diligence in
  investigating the Collateral for hazardous wastes and substances.  Grantor
  hereby (a) releases and waives any future claims against Lender for indemnity
  or contribution in the event Grantor becomes liable for cleanup or other costs
  under any such laws, and (b) agrees to indemnify and hold harmless Lender
  against any and all claims and losses resulting from a breach of this
  provision of this Agreement.  This obligation to indemnify shall survive the
  payment of the Indebtedness and the satisfaction of this Agreement.

  MAINTENANCE OF CASUALTY INSURANCE.  Grantor shall procure and maintain all
  risks insurance, including without limitation fire, theft and liability
  coverage together with such other insurance as Lender may require with respect
  to the Collateral, in form, amounts, coverages and basis reasonably acceptable
  to Lender and issued by a company or companies reasonably acceptable to
  Lender.  Grantor, upon request of Lender, will deliver to Lender from time to
  time the policies or certificates of insurance in form satisfactory to Lender,
  including stipulations that coverages

  PREFERENCE PAYMENTS. Any monies Lender pays because of an asserted preference
  claim in Borrower's bankruptcy will become a part of the Indebtedness and, at
  Lender's option, shall be payable by Borrower as provided above in the
  "EXPENDITURES BY LENDER" paragraph.

  SEVERABLLITY.  If a court of competent jurisdiction finds any provision of
  this Agreement to be invalid or unenforceable as to any person or
  circumstance, such finding shall not render that provision invalid or
  unenforceable as to any other persons or circumstances.  If feasible, any such
  offending provision shall be deemed to be modified to be within the limits of
  enforceability or validity; however, if the offending provision

================================================================================

  cannot be so modified, it shall be stricken and all other provisions of this
  Agreement in all other respects shall remain valid and enforceable.

  SUCCESSOR INTERESTS.  Subject to the limitations set forth above on transfer
  of the Collateral, this Agreement shall be binding upon and inure to the
  benefit of the parties, their successors and assigns.

  WAIVER.  Lender shall not be deemed to have waived any rights under this
  Agreement unless such waiver is given in writing and signed by Lender.  No
  delay or omission on the part of Lender in exercising any right shall operate
  as a waiver of such right or any other right.  A waiver by Lender of a
  provision of this Agreement shall not prejudice or constitute a waiver of
  Lender's right otherwise to demand strict compliance with that provision or
  any other provision of this Agreement.  No prior waiver by Lender, nor any
  course of dealing between Lender and Grantor, shall constitute a waiver of any
  of Lender's rights or of any of Grantor's obligations as to any future
  transactions.  Whenever the consent of Lender is required under this
  Agreement, the granting of such consent by Lender in any instance shall not
  constitute continuing consent to subsequent instances where such consent is
  required and in all cases such consent may be granted or withhold in the sole
  discretion of Lender.

  WAIVER OF CO-OBLIGOR'S RIGHTS.  If more than one person is obligated for the
  Indebtedness, Borrower irrevocably waives, disclaims and relinquishs all
  claims against such other person which Borrower has or would otherwise have by
  virtue of payment of the Indebtedness or any part thereof, specifically
  including but not limited to all rights of indemnity, contribution or
  exoneration.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL SECURITY
AGREEMENT, AND GRANTOR AGREES TO ITS TERMS.  THIS AGREEMENT IS DATED MARCH
13.1997.

================================================================================

INSURANCE REQUIREMENTS.  TIER TECHNOLOGIES, INC. ("Grantor') understands that
insurance coverage is required in connection with the extending of a loan or the
providing of other financial accomodations to Grantor by Lender.  These
requirements are set forth in the security documents.  The following minimum
insurance coverages must be provided on the following described collateral (the
"Collateral"):

COLLATERAL:  ALL INVENTORY AND EQUIPMENT.
   TYPE.  All risks, including fire, theft and liability.
   AMOUNT.  Full insurable value.
   BASIS.  Replacement value.
   ENDORSEMENTS.  Lender's loss payable clause with stipulation that coverage
   will not be canceled or diminished without a minimum of thirty (30) days'
   prior written notice to Lender.

INSURANCE COMPANY.  Grantor may obtain insurance from any insurance company
Grantor may choose that is reasonably acceptable to Lender.  Grantor understands
that credit may not be denied solely because insurance was not purchased through
Lender.

FAILURE TO PROVIDE INSURANCE.  Grantor agrees to deliver to Lender, on or before
closing, evidence of the required insurance as provided above, with an effective
date of March 13, 1997, or earlier.  Grantor acknowledges and agrees that if
Grantor fails to provide any required insurance or fails to continue such
insurance in force, Lender may do so at Grantor's expense as provided in the
applicable security document.  The cost of any such insurance, at the option of
Lender, shall be payable on demand or shall be added to the indebtedness as
provided in the security document. GRANTOR ACKNOWLEDGES THAT IF LENDER SO
PURCHASES ANY SUCH INSURANCE, THE INSURANCE WILL PROVIDE LIMITED PROTECTION
AGAINST PHYSICAL DAMAGE TO THE COLLATERAL, UP TO THE BALANCE OF THE LOAN;
HOWEVER, GRANTOR'S EQUITY IN THE COLLATERAL MAY NOT BE INSURED.  IN ADDITION,
THE INSURANCE MAY NOT PROVIDE ANY PUBLIC LIABILITY OR PROPERTY DAMAGE
INDEMNIFICATION AND MAY NOT MEET THE REQUIREMENTS OF ANY FINANCIAL
RESPONSIBILITY LAWS.

AUTHORIZATION.  For purposes of insurance coverage on the Collateral, Grantor
authorizes Lender to provide to any person (including any insurance agent or
company) all information Lender deems appropriate, whether regarding the

Loan No 704-00488                         (CONTINUED)

================================================================================

   CAPTION HEADINGS.  Caption headings in this Agreement are for convenience
   purposes only and are not to be used to interpret or define the provisions of
   this Agreement.

   MULTIPLE PARTIES; CORPORATE AUTHORITY. All obligations of Borrower under this
   Agreement shall be joint and several, and all references to Borrower shall
   mean each and every Borrower. This means that each of the persons signing
   below is responsible for all obligations in this Agreement.

   CONSENT TO LOAN PARTICIPATION.  Borrower agrees and consents to Lender's sale
   or transfer, whether now or later, of one or more participation interests in
   the Loans to one or more purchasers, whether related or unrelated to Lender.
   Lender may provide, without any limitation whatsoever, to any one or more
   purchasers, or potential purchasers, any information or knowledge Lender may
   have about Borrower or about any other matter relating to the Loan, and
   Borrower hereby waives any rights to privacy it may have with respect to such
   matters.  Borrower additionally waives any and all notices of sale of
   participation interests, as well as all notices of any repurchase of such
   participation interests.  Borrower also agrees that the purchasers of any
   such participation interests will be considered as the absolute owners of
   such interests in the Loans and will have all the rights granted under the
   participation agreement or agreements governing the sale of such
   participation interests.  Borrower further waives all rights of offset or
   counterclaim that it may have now or later against Lender or against any
   purchaser of such a participation interest and unconditionally agrees that
   either Lender or such purchaser may enforce Borrower's obligation under the
   Loans irrespective of the failure or insolvency of any holder of any interest
   in the Loans.  Borrower further agrees that the purchaser of any such
   participation interests may enforce its interests irrespective of any
   personal claims or defenses that Borrower may have against Lender.

   COSTS AND EXPENSES. Borrower agrees to pay upon demand all of Lender's
   expenses, including without limitation attorneys' fees, incurred in
   connection with the preparation, execution, enforcement, modification and
   collection of this Agreement or in connection with the Loans made pursuant to
   this Agreement. Lender may pay someone else to help collect the Loans and to
   enforce this Agreement, and Borrower will pay that amount. This includes,
   subject to any limits under applicable law, Lender's attorneys' fees and
   Lender's legal expenses, whether or not there is a lawsuit, including
   attorneys' fees for bankruptcy proceedings (including efforts to modify or
   vacate any automatic stay or injunction), appeals, and any anticipated post-
   judgment collection services. Borrower also will pay any court costs, in
   addition to all other sums provided by law.

   NOTICES.  All notices required to be given under this Agreement shall be
   given in writing, may be sent by telefacsimile, and shall be effective when
   actually delivered or when deposited with a nationally recognized overnight
   courier or deposited in the United States mail, first class, postage prepaid,
   addressed to the party to whom the notice is to be given at the address shown
   above.  Any party may change its address for notices under this Agreement by
   giving formal written notice to the other parties, specifying that the
   purpose of the notice is to change the party's address.  To the extent
   permitted by applicable law, if there is more than one Borrower, notice to
   any Borrower will constitute notice to all Borrowers.  For notice purposes,
   Borrower will keep Lender informed at all times of Borrower's current
   address(es).

   SEVERABILITY.  If a court of competent jurisdiction finds any provision of
   this Agreement to be invalid or unenforceable as to any person or
   circumstance, such finding shall not render that provision invalid or
   unenforceable as to any other persons or circumstances.  If feasible, any
   such offending provision shall be deemed to be modified to be within the
   limits of enforceability or validity; however, if the offending provision
   cannot be so modified, it shall be stricken and all other provisions of this
   Agreement in all other respects shall remain valid and enforceable.

   SUBSIDIARIES AND AFFILIATES OF BORROWER. To the extent the context of any
   provisions of this Agreement makes it appropriate, including without
   limitation any representation, warranty or covenant, the word "Borrower" as
   used herein shall include all subsidiaries and affiliates of Borrower.
   Notwithstanding the foregoing however, under no circumstances shall this
   Agreement be construed to require Lender to make any Loan or other financial
   accommodation to any subsidiary or affiliate of Borrower.

Loan No 704-00488                         (CONTINUED)

================================================================================

   SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or on
   behalf of Borrower shall bind its successors and assigns and shall inure to
   the benefit of Lender, its successors and assigns. Borrower shall not,
   however, have the right to assign its rights under this Agreement or any
   interest therein, without the prior written consent of Lender.

   SURVIVAL. All warranties, representations, and covenants made by Borrower in
   this Agreement or in any certificate or other instrument delivered by
   Borrower to Lender under this Agreement shall be considered to have been
   relied upon by Lender and will survive the making of the Loan and delivery to
   Lender of the Related Documents, regardless of any investigation made by
   Lender or on Lender's behalf.

   TIME IS OF THE ESSENCE. Time is of the essence in the performance of this
   Agreement.

   WAIVER.  Lender shall not be deemed to have waived any rights under this
   Agreement unless such waiver is given in writing and signed by Lender. No
   delay or omission on the part of Lender in exercising any right shall operate
   as a waiver of such right or any other right. A waiver by Lender of a
   provision of this Agreement shall not prejudice or constitute a waiver of
   Lender's right otherwise to demand strict compliance with that provision or
   any other provision of this Agreement. No prior waiver by Lender, nor any
   course of dealing between Lender and Borrower, or between Lender and any
   Grantor, shall constitute a waiver of any of Lender's rights or of any
   obligations of Borrower or of any Grantor as to any future transactions.
   Whenever the consent of Lender is required under this Agreement, the granting
   of such consent by Lender in any instance shall not constitute continuing
   consent in subsequent instances where such consent is required, and in all
   cases such consent may be granted or withheld in the sole discretion of
   Lender.

BORROWER ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS LOAN AGREEMENT, AND
BORROWER AGREES TO IT TERMS.  THIS AGREEMENT IS DATED AS OF MARCH 13,1997.

BORROWER:  TIER TECHNOLOGIES, INC.             LENDER:  WESTAMERICA BANK

================================================================================

PRINCIPAL AMOUNT: $1,500,000.00   INITIAL RATE: 10.000%  DATE OF NOTE:  MARCH

PROMISE TO PAY. TIER TECHNOLOGIES, INC. ("BORROWER") PROMISES TO PAY TO
WESTAMERICA BANK ("LENDER"), OR ORDER, IN LAWFUL MONEY OF THE UNITED STATES OF
AMERICA, THE PRINCIPAL AMOUNT OF ONE MILLION FIVE HUNDRED THOUSAND & 00/100
DOLLARS ($1,500,000.00) OR SO MUCH AS MAY BE OUTSTANDING, TOGETHER WITH INTEREST
ON THE UNPAID OUTSTANDING PRINCIPAL BALANCE OF EACH ADVANCE. INTEREST SHALL BE
CALCULATED FROM THE DATE OF EACH ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN ON DEMAND, OR IF NO DEMAND IS MADE, IN ONE
PAYMENT OF ALL OUTSTANDING PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON
DECEMBER 31, 1997. IN ADDITION, BORROWER WILL PAY REGULAR MONTHLY PAYMENTS OF
ACCRUED UNPAID INTEREST BEGINNING MARCH 31, 1997, AND ALL SUBSEQUENT INTEREST
PAYMENTS ARE DUE ON THE LAST DAY OF EACH MONTH AFTER THAT. Interest on this Note
is computed on a 365/360 simple interest basis; that is, by applying the ratio
of the annual interest rate over a year of 360 days, multiplied by the
outstanding principal balance, multiplied by the actual number of days the
principal balance is outstanding. Borrower will pay Lender at Lender's address
shown above or at such other place as Lender may designate in writing. Unless
otherwise agreed or required by applicable law, payments will be applied first
to accrued unpaid interest, then to principal, and any remaining amount to any
unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an index which is the Westamerica Bank Index
Rate (the "Index"). THE BANK'S INDEX RATE IS ESTABLISHED BY BANK IN ITS SAN
RAFAEL HEADQUARTERS OFFICE AS OF THE DATE OF THIS NOTE, AND AS OF EACH DATE THAT
BANK MAY ADJUST SUCH INDEX RATE. LOANS MAY BE MADE BY BANK AT, ABOVE OR BELOW
THE INDEX RATE. Lender will tell Borrower the current Index rate upon Borrower's
request. Borrower understands that Lender may make loans based on other rates as
well. The interest rate change will not occur more often than each Day. THE
INDEX CURRENTLY IS 8.250% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE
UNPAID PRINCIPAL BALANCE OF THIS NOTE WILL BE AT A RATE OF 1.750 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 10.000% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Note be more than
the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. Borrower agrees that all loan fees and
other prepaid finance charges are earned fully as of the date of the loan and
will not be subject to refund upon early payment (whether voluntary or as a
result of default), except as otherwise required by law. In any event, even upon
full prepayment of this Note, Borrower understands that Lender is entitled to a
MINIMUM INTEREST CHARGE OF $50.00. Other than Borrower's obligation to pay any
minimum interest charge, Borrower may pay all or a portion of the amount owed
earlier than it is due. Early payments will not, unless agreed to by Lender in
writing, relieve Borrower of Borrower's obligation to continue to make payments
under the payment schedule. Rather, they will reduce the principal balance due
and may result in Borrower's making fewer payments.

DEFAULT.  Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Borrower defaults under any loan, extension of credit,
security agreement, purchase or sales agreement, or any other agreement, in
favor of any other creditor or person that may materially affect any of
Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents. (d) Any
representation or

================================================================================

statement made or furnished to Lender by Borrower or on Borrower's behalf is
false or misleading in any material respect either now or at the time made or
furnished. (e) Borrower becomes insolvent, a receiver is appointed for any part
of Borrower's property, Borrower makes an assignment for the benefit of
creditors, or any proceeding is commenced either by Borrower or against Borrower
under any bankruptcy or insolvency laws. (f) Any creditor tries to take any of
Borrower's property on or in which Lender has a lien or security interest. This
includes a garnishment of any of Borrower's accounts with Lender. (g) Any
guarantor dies or any of the other events described in this default section
occurs with respect to any guarantor of this Note. (h) A material adverse change
occurs in Borrower's financial condition, or Lender believes the prospect of
payment or performance of the Indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon Borrower's failure to pay
all amounts declared due pursuant to this section, including failure to pay upon
final maturity, Lender, at its option, may also, if permitted under applicable
law, increase the variable interest rate on this Note to 5.750 percentage points
over the Index. Lender may hire or pay someone else to help collect this Note if
Borrower does not pay. Borrower also will pay Lender that amount. This includes,
subject to any limits under applicable law, Lender's attorneys' fees and
Lender's legal expenses whether or not there is a lawsuit, including attorneys'
fees and legal expenses for bankruptcy proceedings (including efforts to modify
or vacate any automatic stay or injunction), appeals, and any anticipated post-
judgment collection services. Borrower also will pay any court costs, in
addition to all other sums provided by law. THIS NOTE HAS BEEN DELIVERED TO
LENDER AND ACCEPTED BY LENDER IN THE STATE OF CALIFORNIA. IF THERE IS A LAWSUIT,
BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE
COURTS OF MARIN COUNTY, THE STATE OF CALIFORNIA. LENDER AND BORROWER HEREBY
WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM
BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER. THIS NOTE SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
CALIFORNIA.

DISHONORED ITEM FEE.  Borrower will pay a fee to Lender of $15.00 if Borrower
makes a payment on Borrower's loan and the check or preauthorized charge with
which Borrower pays is later dishonored.

COLLATERAL.  This Note is secured by THAT CERTAIN COMMERCIAL SECURITY AGREEMENT
DATED MARCH 13,1997.

LINE OF CREDIT. This Note evidences a straight line of credit. Once the total
amount of principal has been advanced, Borrower is not entitled to further loan
advances. Advances under this Note may be requested either orally or in writing
by Borrower or by an authorized person. Lender may, but need not, require that
all oral requests be confirmed in writing. All communications, instructions, or
directions by telephone or otherwise to Lender are to be directed to Lender's
office shown above. The following party or parties are authorized to request
advances under the line of credit until Lender receives from Borrower at
Lender's address shown above written notice of revocation of their authority:
WILLIAM G. BARTON, PRESIDENT; JAMES L. BILDNER, CHAIRMAN; AND GEORGE K. ROSS,
SVP/CFO. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Note at any time may be evidenced by endorsements on this Note or by Lender's
internal records, including daily computer print-outs. Lender will have no
obligation to advance funds under this Note if: (a) Borrower or any guarantor is
in default under the terms of this Note or any agreement that Borrower or any
guarantor has with Lender, including any agreement made in connection with the
signing of this Note: (b) Borrower or any guarantor ceases doing business or is
insolvent; (c) any guarantor seeks, claims or otherwise attempts to limit,
modify or revoke such guarantor's guarantee of this Note or any other loan with
Lender; or (d) Borrower has applied funds provided pursuant to this Note for
purposes other than those authorized by

================================================================================

INSURANCE REQUIREMENTS.  TIER TECHNOLOGIES, INC. ("Grantor") understands that
insurance coverage is required in connection with the extending of a loan or the
providing of other financial accomodations to Grantor by Lender.  These
requirements are set forth in the security documents.  The following minimum
insurance coverages must be provided on the following described collateral (the
"Collateral"):

COLLATERAL:    ALL INVENTORY AND EQUIPMENT.
               TYPE.  All risks, including fire, theft and liability.
               AMOUNT.  Full insurable value.
               BASIS.  Replacement value.
               ENDORSEMENTS. Lender's loss payable clause with stipulation that
               coverage will not be cancelled or diminished without a minimum of
               thirty (30) days' prior written notice to Lender.

INSURANCE COMPANY. Grantor may obtain insurance from any insurance company
Grantor may choose that is reasonably acceptable to Lender. Grantor understands
that credit may not be denied solely because insurance was not purchased through
Lender.

FAILURE TO PROVIDE INSURANCE. Grantor agrees to deliver to Lender, on or before
closing, evidence of the required insurance as provided above, with an effective
date of March 13, 1997, or earlier. Grantor acknowledges and agrees that if
Grantor fails to provide any required insurance or fails to continue such
insurance in force, Lender may do so at Grantor's expense as provided in the
applicable security document. The cost of any such insurance, at the option of
Lender, shall be payable on demand or shall be added to the indebtedness as
provided in the security document. GRANTOR ACKNOWLEDGES THAT IF LENDER SO
PURCHASES ANY SUCH INSURANCE, THE INSURANCE WILL PROVIDE LIMITED PROTECTION
AGAINST PHYSICAL DAMAGE TO THE COLLATERAL, UP TO THE BALANCE OF THE LOAN;
HOWEVER, GRANTOR'S EQUITY IN THE COLLATERAL MAY NOT BE INSURED. IN ADDITION, THE
INSURANCE MAY NOT PROVIDE ANY PUBLIC LIABILITY OR PROPERTY DAMAGE
INDEMNIFICATION AND MAY NOT MEET THE REQUIREMENTS OF ANY FINANCIAL
RESPONSIBILITY LAWS.

AUTHORIZATION. For purposes of insurance coverage on the Collateral, Grantor
authorizes Lender to provide to any person (including any insurance agent or
company) all information Lender deems appropriate, whether regarding the
Collateral, the loan or other financial accomodations, or both.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS AGREEMENT TO PROVIDE
INSURANCE AND AGREES TO ITS TERMS.  THIS AGREEMENT IS DATED MARCH 13,1997.

================================================================================
 
AMOUNT OF GUARANTY.  THE PRINCIPAL AMOUNT OF THIS GUARANTY IS FOUR MILLION THREE
HUNDRED THOUSAND & 00/100 DOLLARS ($4,300,000.00).

CONTINUING GUARANTY.  FOR GOOD AND VALUABLE CONSIDERATION, BRADLEY H. NICKELS
("GUARANTOR") ABSOLUTELY AND UNCONDITIONALLY GUARANTEES AND PROMISES TO PAY TO
WESTAMERICA BANK ("LENDER") OR ITS ORDER, ON DEMAND, IN LEGAL TENDER OF THE
UNITED STATES OF AMERICA, THE INDEBTEDNESS (AS THAT TERM IS DEFINED BELOW) OF
TIER TECHNOLOGIES, INC. ("BORROWER") TO LENDER ON THE TERMS AND CONDITIONS SET
FORTH IN THIS GUARANTY.  THE OBLIGATIONS OF GUARANTOR UNDER THIS GUARANTY ARE
CONTINUING.

DEFINITIONS.  The following words shall have the following meanings when used in
this Guaranty:

   BORROWER.  The word "Borrower" means TIER TECHNOLOGIES, INC..

   GUARANTOR.  The word "Guarantor" means BRADLEY H. NICKELS.

   GUARANTY.  The word "Guaranty" means this Guaranty made by Guarantor for the
   benefit of Lender dated May 31, 1997.

   INDEBTEDNESS.  The word "Indebtedness" is used in its most comprehensive
   sense and means and includes any and all of Borrower's liabilities,
   obligations, debts, and indebtedness to Lender, now existing or hereinafter
   incurred or created, including, without limitation, all loans, advances,
   interest, costs, debts, overdraft indebtedness, credit card indebtedness,
   lease obligations, other obligations, and liabilities of Borrower, or any of
   them, and any present or future judgments against Borrower, or any of them;
   and whether any such Indebtedness is voluntarily or involuntarily incurred,
   due or not due, absolute or contingent, liquidated or unliquidated,
   determined or undetermined; whether Borrower may be liable individually or
   jointly with others, or primarily or secondarily, or as guarantor or surety;
   whether recovery on the Indebtedness may be or may become barred or
   unenforceable against Borrower for any reason whatsoever; and whether the
   Indebtedness arises from transactions which may be voidable on account of
   infancy, insanity, ultra vires, or otherwise.

   LENDER.  The word "Lender" means WESTAMERICA BANK, its successors and
   assigns.

   RELATED DOCUMENTS.  The words "Related Documents' mean and include without
   limitation all promissory notes, credit agreements, loan agreements,

   of trust, and all other instruments, agreements and documents, whether now or
   hereafter existing, executed in connection with the Indebtedness.

MAXIMUM LIABILITY.  THE MAXIMUM LIABILITY OF GUARANTOR UNDER THIS GUARANTY SHALL
NOT EXCEED AT ANY ONE TIME THE SUM OF THE PRINCIPAL AMOUNT OF $4,300,000.00,
PLUS ALL INTEREST THEREON, PLUS ALL OF LENDER'S COSTS, EXPENSES, AND ATTORNEYS'
FEES INCURRED IN CONNECTION WITH OR RELATING TO (A) THE COLLECTION OF THE
INDEBTEDNESS, (B) THE COLLECTION AND SALE OF ANY COLLATERAL FOR THE INDEBTEDNESS
OR THIS GUARANTY, OR (C) THE ENFORCEMENT OF THIS GUARANTY.

05-31-1997                         COMMERCIAL GUARANTY
Loan No 704-00491                       (CONTINUED)

================================================================================

ATTORNEYS' FEES INCLUDE, WITHOUT LIMITATION, ATTORNEYS' FEES WHETHER OR NOT
THERE IS A LAWSUIT, AND IF THERE IS A LAWSUIT, ANY FEES AND COSTS FOR TRIAL AND
APPEALS.

The above limitation on liability is not a restriction on the amount of the
Indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative. This Guaranty shall not (unless specifically provided below
to the contrary) affect or invalidate any such other guaranties. The liability
of Guarantor will be the aggregate liability of Guarantor under the terms of
this Guaranty and any such other unterminated guaranties.

NATURE OF GUARANTY.  Guarantor's liability under this Guaranty shall be open and
continuous for so long as this Guaranty remains in force.  Guarantor intends to
guarantee at all times the performance and prompt payment when due, whether at
maturity or earlier by reason of acceleration or otherwise, of all Indebtedness
within the limits set forth in the preceding section of this Guaranty.
Accordingly, no payments made upon the Indebtedness will discharge or diminish
the continuing liability of Guarantor in connection with any remaining portions
of the Indebtedness or any of the Indebtedness which subsequently arises or is
thereafter incurred or contracted.  Any married person who signs this Guaranty
hereby expressly agrees that recourse under this agreement may be had against
both his or her separate property and community property, whether now owned or
hereafter acquired.

DURATION OF GUARANTY.  This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by Lender of any notice of revocation shall have been
fully and finally paid and satisfied and all other obligations of Guarantor
under this Guaranty shall have been performed in full.  If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing.  Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at the address
of Lender listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by Lender of Guarantor's written
revocation.  For this purpose and without limitation, the term "new
Indebtedness" does not include Indebtedness which at the lime of notice of
revocation is contingent, unliquidated, undetermined or not due and which later
becomes absolute, liquidated, determined or due.  This Guaranty will continue to
bind Guarantor for all Indebtedness incurred by Borrower or committed by Lender
prior to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness.  All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness.  This Guaranty shall
bind the estate of Guarantor as to Indebtedness created both before and after
the death or incapacity of Guarantor, regardless of Lender's actual notice of
Guarantor's death.  Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect.  Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty.  A revocation received by Lender from any one or more Guarantors shall
not affect the liability of any remaining Guarantors under this Guaranty.  IT IS
ANTICIPATED THAT FLUCTUATIONS MAY OCCUR IN THE AGGREGATE AMOUNT OF INDEBTEDNESS
COVERED BY THIS GUARANTY, AND IT IS SPECIFICALLY ACKNOWLEDGED AND AGREED BY
GUARANTOR THAT REDUCTIONS IN THE AMOUNT OF INDEBTEDNESS, EVEN TO ZERO DOLLARS
($0.00), PRIOR TO WRITTEN REVOCATION OF THIS GUARANTY BY GUARANTOR SHALL NOT
CONSTITUTE A TERMINATION OF THIS GUARANTY.  THIS GUARANTY IS BINDING UPON
GUARANTOR AND GUARANTOR'S HEIRS, SUCCESSORS AND ASSIGNS SO LONG AS ANY OF THE
GUARANTEED INDEBTEDNESS REMAINS UNPAID AND EVEN THOUGH THE INDEBTEDNESS
GUARANTEED MAY FROM TIME TO TIME BE ZERO DOLLARS ($0.00).

GUARANTOR'S AUTHORIZATION TO LENDER.  Guarantor authorizes Lender, either before
or after any revocation hereof, WITHOUT NOTICE OR DEMAND AND WITHOUT LESSENING
GUARANTOR'S LIABILITY UNDER THIS GUARANTY, FROM TIME TO TIME: (A) PRIOR TO
REVOCATION AS SET FORTH ABOVE, TO MAKE ONE OR MORE ADDITIONAL SECURED LOANS TO
BORROWER, TO LEASE EQUIPMENT OR OTHER GOODS TO BORROWER, OR OTHERWISE TO EXTEND
ADDITIONAL CREDIT TO BORROWER; (B) TO ALTER, COMPROMISE, RENEW, EXTEND,
ACCELERATE, OR OTHERWISE CHANGE ONE OR MORE TIMES THE TIME FOR PAYMENT OR OTHER
TERMS OF THE INDEBTEDNESS OR ANY PART OF THE INDEBTEDNESS, INCLUDING INCREASES
AND DECREASES OF THE RATE OF

INDEBTEDNESS; (F) TO APPLY SUCH SECURITY AND DIRECT THE ORDER OR MANNER OF SALE

TERMS OF THE CONTROLLING SECURITY AGREEMENT OR DEED OF TRUST AS LENDER IN ITS
DISCRETION MAY DETERMINE; (G) TO SELL, TRANSFER, ASSIGN, OR GRANT PARTICIPATIONS
IN ALL OR ANY PART OF THE INDEBTEDNESS; AND (H) TO ASSIGN OR TRANSFER THIS
GUARANTY IN WHOLE OR IN PART.

GUARANTOR'S REPRESENTATIONS AND WARRANTIES.  Guarantor represents and warrants
to Lender that (a) no representations or agreements of any kind have been made
to Guarantor which would limit or qualify in any way the terms of this Guaranty;
(b) this Guaranty is executed at Borrower's request and not at the request of
Lender; (c) Guarantor has full power, right and authority to enter into this
Guaranty; (d) the provisions of this Guaranty do not conflict with or result in
a default under any agreement or other instrument binding upon Guarantor and do
not result in a violation of any law, regulation, court decree or order
applicable to Guarantor; (e) Guarantor has not and will not, without the prior
written consent of Lender, sell, lease, assign, encumber, hypothecate, transfer,
or otherwise dispose of all or substantially all of Guarantor's assets, or any
interest therein; (f) upon Lender's request, Guarantor will provide to Lender
financial and credit information in form acceptable to Lender, and all such
financial information which currently has been, and all future financial
information which will be provided to Lender is and will be true and correct in
all material respects and fairly present the financial condition of Guarantor as
of the dates the financial information is provided; (g) no material adverse
change has occurred in Guarantor's financial condition since the date of the
most recent financial statements provided to Lender and no event has occurred
which may materially adversely affect Guarantor's financial condition; (h) no
litigation, claim, investigation, administrative proceeding or similar action
(including those for unpaid taxes) against Guarantor is pending or threatened;
(i) Lender has made no representation to Guarantor as to the creditworthiness of
Borrower; and (j) Guarantor has established adequate means of obtaining from
Borrower on a continuing basis information regarding Borrower's financial
condition.  Guarantor agrees to keep adequately informed from such means of any
facts, events, or circumstances which might in any way affect Guarantor's risks
under this Guaranty, and Guarantor further agrees that, absent a request for
information, Lender shall have no obligation to disclose to Guarantor any
information or documents acquired by Lender in the course of its relationship
with Borrower.

GUARANTOR'S WAIVERS.  Except as prohibited by applicable law, Guarantor waives
any right to require Lender to (a) make any presentment, protest, demand, or
notice of any kind, including notice of change of any terms of repayment of the
Indebtedness, default by Borrower or any other guarantor or surety, any action
or nonaction taken by Borrower, Lender, or any other guarantor or surety of
Borrower, or the creation of new or additional Indebtedness; (b) proceed against
any person, including Borrower, before proceeding against Guarantor; (c) proceed
against any collateral for the Indebtedness, including Borrower's collateral,
before proceeding against Guarantor; (d) apply any payments or proceeds received
against the Indebtedness in any order; (e) give notice of the terms, time, and
place of any sale of the collateral pursuant to the Uniform Commercial Code or
any other law governing such sale; (f) disclose any information about the
Indebtedness, the Borrower, the collateral, or any other guarantor or surety, or
about any action or nonaction of Lender; or (g) pursue any remedy or course of
action in Lender's power whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (h)
any disability or other defense of Borrower, any other guarantor or surety or
any other person; (i) the cessation from any cause whatsoever, other than
payment in full, of the Indebtedness; 0) the application of proceeds of the
Indebtedness by Borrower for purposes other than the purposes understood and
intended by Guarantor and Lender; (k) any act of omission or commission by
Lender which directly or indirectly results in or contributes to the discharge
of Borrower or any other guarantor or surety, or the Indebtedness, or the loss
or release of any collateral by operation of law or otherwise; (l) any statute
of limitations in any action under this Guaranty or on the Indebtedness; or (m)
any modification or change in terms of the Indebtedness, whatsoever, including
without limitation, the renewal,

================================================================================

extension, acceleration, or other change in the time payment of the Indebtedness
is due and any change in the interest rate, and including any such modification
or change in terms after revocation of this Guaranty on Indebtedness incurred
prior to such revocation.

Guarantor waives all rights and any defenses arising out of an election of
remedies by Lender even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for a guaranteed obligation, has destroyed
Guarantor's rights of subrogation and reimbursement against Borrower by
operation of Section 580d of the California Code of Civil Procedure or
otherwise.

Guarantor waives all rights and defenses that Guarantor may have because
Borrower's obligation is secured by real property.  This means among other
things: (1) Lender may collect from Guarantor without first foreclosing on any
real or personal property collateral pledged by Borrower. (2) If Lender
forecloses on any real property collateral pledged by Borrower: (A) The amount
of Borrower's obligation may be reduced only by the price for which the
collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price. (B) Lender may collect from Guarantor even if Lender, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from Borrower.  This is an unconditional waiver of any
rights and defenses Guarantor may have because Borrower's obligation is secured
by real property.  These rights and defenses include, but are not limited to,
any rights and defenses based upon Section 580a, 580b, 580d, or 726 of the Code
of Civil Procedure.

Guarantor understands and agrees that the foregoing waivers are waivers of
substantive rights and defenses to which Guarantor might otherwise be entitled
under state and federal law.  The rights and defenses waived include, without
limitation, those provided by California laws of suretyship and guaranty, anti-
deficiency laws, and the Uniform Commercial Code.  Guarantor acknowledges that
Guarantor has provided these waivers of rights and defenses with the intention
that they be fully relied upon by Lender.  Until all Indebtedness is paid in
full, Guarantor waives any right to enforce any remedy Lender may have against
Borrower or any other guarantor, surety, or other person, and further, Guarantor
waives any right to participate in any collateral for the Indebtedness now or
hereafter held by Lender.

If now or hereafter (a) Borrower shall be or become insolvent, and (b) the
Indebtedness shall not at all times until paid be fully secured by collateral
pledged by Borrower, Guarantor hereby forever waives and relinquishes in favor
of Lender and Borrower, and their respective successors, any claim or right to
payment Guarantor may now have or hereafter have or acquire against Borrower, by
subrogation or otherwise, so that at no time shall Guarantor be or become a
"creditor" of Borrower within the meaning of I 1 U.S.C. section 547(b), or any
successor provision of the Federal bankruptcy laws.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS.  Guarantor warrants and
agrees that each of the waivers set forth above is made with Guarantor's full
knowledge of its significance and consequences and that, under the
circumstances, the waivers are reasonable and not contrary to public policy or
law.  If any such waiver is determined to be contrary to any applicable law or
public policy, such waiver shall be effective only to the extent permitted by
law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR.  Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter created,
shall be prior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent.  Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower.  In the event of insolvency and consequent liquidation of the assets
of Borrower, through bankruptcy, by an assignment for the benefit of creditors,
by voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims of both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the Indebtedness of Borrower to payment of
the claims of both Lender and Guarantor shall be paid to Lender and shall be
first applied by Lender to the Indebtedness of Borrower to Lender.  Guarantor
does hereby assign to Lender all claims which it may have or acquire against
Borrower or against any assignee or trustee in bankruptcy of Borrower; provided

such assignment shall be effective only for the purpose of assuring to Lender
full payment in legal tender of the Indebtedness. If Lender so requests, any
notes or credit agreements now or hereafter evidencing any debts or obligations
of Borrower to Guarantor shall be marked with a legend that the same are subject
to this Guaranty and shall be delivered to Lender. Guarantor agrees, and Lender
hereby is authorized, in the name of Guarantor, from time to time to execute and
file financing statements and continuation statements and to execute such other
documents and to take such other actions as Lender deems necessary or
appropriate to perfect, preserve and enforce its rights under this Guaranty.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Guaranty:

   INTEGRATION, AMENDMENT.  Guarantor warrants, represents and agrees that this
   Guaranty, together with any exhibits or schedules incorporated herein, fully
   incorporates the agreements and understandings of Guarantor with Lender with
   respect to the subject matter hereof and all prior negotiations, drafts, and
   other extrinsic communications between Guarantor and Lender shall have no
   evidentiary effect whatsoever.  Guarantor further agrees that Guarantor has
   read and fully understands the terms of this Guaranty; Guarantor has had the
   opportunity to be advised by Guarantor's attorney with respect to this
   Guaranty; the Guaranty fully reflects Guarantor's intentions and parol
   evidence is not required to interpret the terms of this Guaranty.  Guarantor
   hereby indemnifies and holds Lender harmless from all losses, claims,
   damages, and costs (including Lender's attorneys' fees) suffered or incurred
   by Lender as a result of any breach by Guarantor of the warranties,
   representations and agreements of this paragraph.  No alteration or amendment
   to this Guaranty shall be effective unless given in writing and signed by the
   parties sought to be charged or bound by the alteration or amendment.
 
   APPLICABLE LAW.  This Guaranty has been delivered to Lender and accepted by
   Lender in the State of California.  If there is a lawsuit, Guarantor agrees
   upon Lender's request to submit to the jurisdiction of the courts of MARIN
   County, State of California.  Lender and Guarantor hereby waive the right to
   any jury trial in any action, proceeding, or counterclaim brought by either
   Lender or Guarantor against the other.  This Guaranty shall be governed by
   and construed in accordance with the laws of the State of California.

   ATTORNEYS' FEES; EXPENSES.  Guarantor agrees to pay upon demand all of
   Lender's costs and expenses, including attorneys' fees and Lender's legal
   expenses, incurred in connection with the enforcement of this Guaranty.
   Lender may pay someone else to help enforce this Guaranty, and Guarantor
   shall pay the costs and expenses of such enforcement.  Costs and expenses
   include Lender's attorneys' fees and legal expenses whether or not there is a
   lawsuit, including attorneys' fees and legal expenses for bankruptcy
   proceedings (and including efforts to modify or vacate any automatic stay or
   injunction), appeals, and any anticipated post-judgment collection services.
   Guarantor also shall pay all court costs and such additional fees as may be
   directed by the court.

   NOTICES.  All notices required to be given by either party to the other under
   this Guaranty shall be in writing, may be sent by telefacsimile, and, except
   for revocation notices by Guarantor, shall be effective when actually
   delivered or when deposited with a nationally recognized overnight courier,
   or when deposited in the United States mail, first class postage prepaid,
   addressed to the party to whom the notice is to be given at the address shown
   above or to such other addresses as either party may designate to the other
   in writing.  All revocation notices by Guarantor shall be in writing and
   shall be effective only upon delivery to Lender as provided above in the
   section titled "DURATION OF GUARANTY." If there is more than one Guarantor,
   notice to any Guarantor will constitute notice to all Guarantors.  For notice
   purposes, Guarantor agrees to keep Lender informed at all times of
   Guarantor's current address.

   INTERPRETATION.  In all cases where there is more than one Borrower or
   Guarantor, then all words used in this Guaranty in the singular shall be
   deemed to have been used in the plural where the context and construction so
   require; and where there is more than one Borrower named in this Guaranty or
   when this Guaranty is executed by more than one Guarantor, the words
   "Borrower" and "Guarantor" respectively shall mean all and any one or more of
   them.  The words "Guarantor," "Borrower," and "Lender" include the heirs,
   successors,

   assigns, and transferees of each of them. Caption headings in this Guaranty
   are for convenience purposes only and are not to be used to interpret or
   define the provisions of this Guaranty. If a court of competent jurisdiction
   finds any provision of this Guaranty to be invalid or unenforceable as to any
   person or circumstance, such finding shall not render that provision invalid
   or unenforceable as to any other persons or circumstances, and all provisions
   of this Guaranty in all other respects shall remain valid and enforceable. If
   any one or more of Borrower or Guarantor are corporations or partnerships, it
   is not necessary for Lender to inquire into the powers of Borrower or
   Guarantor or of the officers, directors, partners, or agents acting or
   purporting to act on their behalf, and any Indebtedness made or created in
   reliance upon the professed exercise of such powers shall be guaranteed under
   this Guaranty.

   WAIVER.  Lender shall not be deemed to have waived any rights under this
   Guaranty unless such waiver is given in writing and signed by Lender.  No
   delay or omission on the part of Lender in exercising any right shall operate
   as a waiver of such right or any other right.  A waiver by Lender of a
   provision of this Guaranty shall not prejudice or constitute a waiver of
   Lender's right otherwise to demand strict compliance with that provision or
   any other provision of this Guaranty.  No prior waiver by Lender, nor any
   course of dealing between Lender and Guarantor, shall constitute a waiver of
   any of Lender's rights or of any of Guarantor's obligations as to any future
   transactions.  Whenever the consent of Lender is required under this
   Guaranty, the granting of such consent by Lender in any instance shall not
   constitute continuing consent to subsequent instances where such consent is
   required and in all cases such consent may be granted or withheld in the sole
   discretion of Lender.

EACH UNDERSIGNED GUARANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS
GUARANTY AND AGREES TO ITS TERMS.  IN ADDITION, EACH GUARANTOR UNDERSTANDS THAT

CONTINUING GUARANTY.  FOR GOOD AND VALUABLE CONSIDERATION, BRYAN D. MCCAUL
("GUARANTOR") ABSOLUTELY AND UNCONDITIONALLY GUARANTEES AND PROMISES TO PAY TO
WESTAMERICA BANK ("LENDER") OR ITS ORDER, ON DEMAND, IN LEGAL TENDER OF THE

   due or not due, absolute or contingent, liquidated or unliquidated,
   determined or undetermined; whether Borrower may be liable individually or
   jointly with others, or primarily or secondarily, or as guarantor or surety;
   whether recovery on the Indebtedness may be or may become barred or

FEES INCURRED IN CONNECTION WITH OR RELATING TO (A) THE COLLECTION OF THE

OR THIS GUARANTY, OR (C) THE ENFORCEMENT OF THIS GUARANTY.

LOAN NO 704-00491              (CONTINUED)

================================================================================

ATTORNEYS' FEES INCLUDE, WITHOUT LIMITATION, ATTORNEYS' FEES WHETHER OR NOT
THERE IS A LAWSUIT, AND IF THERE IS A LAWSUIT, ANY FEES AND COSTS FOR TRIAL AND
APPEALS.

The above limitation on liability is not a restriction on the amount of the
Indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative.  This Guaranty shall not (unless specifically provided
below to the contrary) affect or invalidate any such other guaranties.  The
liability of Guarantor will be the aggregate liability of Guarantor under the
terms of this Guaranty and any such other unterminated guaranties.

NATURE OF GUARANTY.  Guarantor's liability under this Guaranty shall be open and
continuous for so long as this Guaranty remains in force.  Guarantor intends to
guarantee at all times the performance and prompt payment when due, whether at
maturity or earlier by reason of acceleration or otherwise, of all Indebtedness
within the limits set forth in the preceding section of this Guaranty.
Accordingly, no payments made upon the Indebtedness will discharge or diminish
the continuing liability of Guarantor in connection with any remaining portions
of the Indebtedness or any of the Indebtedness which subsequently arises or is
thereafter incurred or contracted.  Any married person who signs this Guaranty
hereby expressly agrees that recourse may be had against both his or her
separate property and community property.

DURATION OF GUARANTY.  This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by Lender of any notice of revocation shall have been
fully and finally paid and satisfied and all other obligations of Guarantor
under this Guaranty shall have been performed in full.  If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing.  Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at the address
of Lender listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by Lender of Guarantor's written
revocation.  For this purpose and without limitation, the term "new
Indebtedness" does not include Indebtedness which at the time of notice of
revocation is contingent, unliquidated, undetermined or not due and which later
becomes absolute, liquidated, determined or due.  This Guaranty will continue to
bind Guarantor for all Indebtedness incurred by Borrower or committed by Lender
prior to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness.  All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness.  This Guaranty shall
bind the estate of Guarantor as to Indebtedness created both before and after
the death or incapacity of Guarantor, regardless of Lender's actual notice of
Guarantor's death.  Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect.  Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty.  A revocation received by Lender from any one or more Guarantors shall
not affect the liability of any remaining Guarantors under this Guaranty.  IT IS
ANTICIPATED THAT FLUCTUATIONS MAY OCCUR IN THE AGGREGATE AMOUNT OF INDEBTEDNESS
COVERED BY THIS GUARANTY, AND IT IS SPECIFICALLY ACKNOWLEDGED AND AGREED BY
GUARANTOR THAT REDUCTIONS IN THE AMOUNT OF INDEBTEDNESS, EVEN TO ZERO DOLLARS
($0.00), PRIOR TO WRITTEN REVOCATION OF THIS GUARANTY BY GUARANTOR SHALL NOT
CONSTITUTE A TERMINATION OF THIS GUARANTY.  THIS GUARANTY IS BINDING UPON
GUARANTOR AND GUARANTOR'S HEIRS, SUCCESSORS AND ASSIGNS SO LONG AS ANY OF THE
GUARANTEED INDEBTEDNESS REMAINS UNPAID AND EVEN THOUGH THE INDEBTEDNESS
GUARANTEED MAY FROM TIME TO TIME BE ZERO DOLLARS ($0.00).

GUARANTOR'S AUTHORIZATION TO LENDER.  Guarantor authorizes Lender, either before
or after any revocation hereof, WITHOUT NOTICE OR DEMAND AND WITHOUT LESSENING
GUARANTOR'S LIABILITY UNDER THIS GUARANTY, FROM TIME TO TIME: (A) PRIOR TO
REVOCATION AS SET FORTH ABOVE, TO MAKE ONE OR MORE ADDITIONAL SECURED OR
UNSECURED LOANS TO BORROWER, TO LEASE EQUIPMENT OR OTHER GOODS TO BORROWER, OR
OTHERWISE TO EXTEND ADDITIONAL CREDIT TO BORROWER; (B) TO ALTER, COMPROMISE,
RENEW, EXTEND, ACCELERATE, OR OTHERWISE CHANGE ONE OR MORE TIMES THE TIME FOR
PAYMENT OR OTHER TERMS OF THE INDEBTEDNESS OR ANY PART OF THE INDEBTEDNESS,
INCLUDING INCREASES AND DECREASES OF THE RATE OF

INTEREST ON THE INDEBTEDNESS; EXTENSIONS MAY BE REPEATED AND MAY BE FOR LONGER

SUE, OR DEAL WITH ANY ONE OR MORE OF BORROWER'S SURETIES, ENDORSERS, OR OTHER
GUARANTORS ON ANY TERMS OR IN ANY MANNER LENDER MAY CHOOSE; (E) TO DETERMINE
HOW, WHEN AND WHAT APPLICATION OF PAYMENTS AND CREDITS SHALL BE MADE ON THE
INDEBTEDNESS; (F) TO APPLY SUCH SECURITY AND DIRECT THE ORDER OR MANNER OF SALE
THEREOF, INCLUDING WITHOUT LIMITATION, ANY NONJUDICIAL SALE PERMITTED BY THE
TERMS OF THE CONTROLLING SECURITY AGREEMENT OR DEED OF TRUST AS LENDER IN ITS
DISCRETION MAY DETERMINE; (G) TO SELL, TRANSFER, ASSIGN, OR GRANT PARTICIPATIONS
IN ALL OR ANY PART OF THE INDEBTEDNESS; AND (H) TO ASSIGN OR TRANSFER THIS
GUARANTY IN WHOLE OR IN PART.

GUARANTOR'S REPRESENTATIONS AND WARRANTIES.  Guarantor represents and warrants
to Lender that (a) no representations or agreements of any kind have been made
to Guarantor which would limit or qualify in any way the terms of this Guaranty;
(b) this Guaranty is executed at Borrower's request and not at the request of
Lender; (c) Guarantor has full power, right and authority to enter into this
Guaranty; (d) the provisions of this Guaranty do not conflict with or result in
a default under any agreement or other instrument binding upon Guarantor and do
not result in a violation of any law, regulation, court decree or order
applicable to Guarantor; (e) Guarantor has not and will not, without the prior
written consent of Lender, sell, lease, assign, encumber, hypothecate, transfer,
or otherwise dispose of all or substantially all of Guarantor's assets, or any
interest therein; (f) upon Lender's request, Guarantor will provide to Lender
financial and credit information in form acceptable to Lender, and all such
financial information which currently has been, and all future financial
information which will be provided to Lender is and will be true and correct in
all material respects and fairly present the financial condition of Guarantor as
of the dates the financial information is provided; (g) no material adverse
change has occurred in Guarantor's financial condition since the date of the
most recent financial statements provided to Lender and no event has occurred
which may materially adversely affect Guarantor's financial condition; (h) no
litigation, claim, investigation, administrative proceeding or similar action
(including those for unpaid taxes) against Guarantor is pending or threatened;
(i) Lender has made no representation to Guarantor as to the creditworthiness of
Borrower; and (j) Guarantor has established adequate means of obtaining from
Borrower on a continuing basis information regarding Borrower's financial
condition.  Guarantor agrees to keep adequately informed from such means of any
facts, events, or circumstances which might in any way affect Guarantor's risks
under this Guaranty, and Guarantor further agrees that, absent a request for
information, Lender shall have no obligation to disclose to Guarantor any
information or documents acquired by Lender in the course of its relationship
with Borrower.

GUARANTOR'S WAIVERS.  Except as prohibited by applicable law, Guarantor waives
any right to require Lender to (a) make any presentment, protest, demand, or
notice of any kind, including notice of change of any terms of repayment of the
Indebtedness, default by Borrower or any other guarantor or surety, any action
or nonaction taken by Borrower, Lender, or any other guarantor or surety of
Borrower, or the creation of new or additional Indebtedness; (b) proceed against
any person, including Borrower, before proceeding against Guarantor; (c) proceed
against any collateral for the Indebtedness, including Borrower's collateral,
before proceeding against Guarantor; (d) apply any payments or proceeds received
against the Indebtedness in any order; (e) give notice of the terms, time, and
place of any sale of the collateral pursuant to the Uniform Commercial Code or
any other law governing such sale; (f) disclose any information about the
Indebtedness, the Borrower, the collateral, or any other guarantor or surety, or
about any action or nonaction of Lender; or (g) pursue any remedy or course of
action in Lender's power whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (h)
any disability or other defense of Borrower, any other guarantor or surety or
any other person; (i) the cessation from any cause whatsoever, other than
payment in full, of the Indebtedness; (j) the application of proceeds of the
Indebtedness by Borrower for purposes other than the purposes understood and
intended by Guarantor and Lender; (k) any act of omission or commission by
Lender which directly or indirectly results in or contributes to the discharge
of Borrower or any other guarantor or surety, or the Indebtedness, or the loss
or release of any collateral by operation of law or otherwise; (l) any statute
of limitations in any action under this Guaranty or on the Indebtedness; or (m)
any modification or change in terms of the Indebtedness, whatsoever, including
without limitation, the renewal,

================================================================================

extension, acceleration, or other change in the time payment of the Indebtedness
is due and any change in the interest rate, and including any such modification
or change in terms after revocation of this Guaranty on Indebtedness incurred
prior to such revocation.

Guarantor waives all rights and any defenses arising out of an election of
remedies by Lender even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for a guaranteed obligation, has destroyed
Guarantor's rights of subrogation and reimbursement against Borrower by
operation of Section 580d of the California Code of Civil Procedure or
otherwise.

Guarantor waives all rights and defenses that Guarantor may have because
Borrower's obligation is secured by real property.  This means among other
things: (1) Lender may collect from Guarantor without first foreclosing on any
real or personal property collateral pledged by Borrower. (2) If Lender
forecloses on any real property collateral pledged by Borrower: (A) The amount
of Borrower's obligation may be reduced only by the price for which the
collateral is sold at the foreclosure sale, even it the collateral is worth more
than the sale price. (B) Lender may collect from Guarantor even if Lender, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from Borrower.  This is an unconditional waiver of any
rights and defenses Guarantor may have because Borrower's obligation is secured
by real property.  These rights and defenses include, but are not limited to,
any rights and defenses based upon Section 580a, 580b, 580d, or 726 of the Code
of Civil Procedure.

Guarantor understands and agrees that the foregoing waivers are waivers of
substantive rights and defenses to which Guarantor might otherwise be entitled
under state and federal law.  The rights and defenses waived include, without
limitation, those provided by California laws of suretyship and guaranty, anti-
deficiency laws, and the Uniform Commercial Code.  Guarantor acknowledges that
Guarantor has provided these waivers of rights and defenses with the intention
that they be fully relied upon by Lender.  Until all Indebtedness is paid in
full, Guarantor waives any right to enforce any remedy Lender may have against
Borrower or any other guarantor, surety, or other person, and further, Guarantor
waives any right to participate in any collateral for the Indebtedness now or
hereafter held by Lender.

If now or hereafter (a) Borrower shall be or become insolvent, and (b) the
Indebtedness shall not at all times until paid be fully secured by collateral
pledged by Borrower, Guarantor hereby forever waives and relinquishes in favor
of Lender and Borrower, and their respective successors, any claim or right to
payment Guarantor may now have or hereafter have or acquire against Borrower, by
subrogation or otherwise, so that at no time shall Guarantor be or become a
"creditor" of Borrower within the meaning of 11 U.S.C. section 547(b), or any
successor provision of the Federal bankruptcy laws.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS.  Guarantor warrants and
agrees that each of the waivers set forth above is made with Guarantor's full
knowledge of its significance and consequences and that, under the
circumstances, the waivers are reasonable and not contrary to public policy or
law.  If any such waiver is determined to be contrary to any applicable law or
public policy, such waiver shall be effective only to the extent permitted by
law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR.  Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter created,
shall be prior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent.  Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower.  In the event of insolvency and consequent liquidation of the assets
of Borrower, through bankruptcy, by an assignment for the benefit of creditors,
by voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims of both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that

================================================================================

such assignment shall be effective only for the purpose of assuring to Lender
full payment in legal tender of the Indebtedness. If Lender so requests, any
notes or credit agreements now or hereafter evidencing any debts or obligations
of Borrower to

Guarantor shall be marked with a legend that the same are subject to this
Guaranty and shall be delivered to Lender.  Guarantor agrees, and Lender hereby
is authorized, in the name of Guarantor, from time to time to execute and file
financing statements and continuation statements and to execute such other
documents and to take such other actions as Lender deems necessary or
appropriate to perfect, preserve and enforce its rights under this Guaranty.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Guaranty:

   INTEGRATION, AMENDMENT.  Guarantor warrants, represents and agrees that this
   Guaranty, together with any exhibits or schedules incorporated herein, fully
   incorporates the agreements and understandings of Guarantor with Lender with
   respect to the subject matter hereof and all prior negotiations, drafts, and
   other extrinsic communications between Guarantor and Lender shall have no
   evidentiary effect whatsoever.  Guarantor further agrees that Guarantor has
   read and fully understands the terms of this Guaranty; Guarantor has had the
   opportunity to be advised by Guarantor's attorney with respect to this
   Guaranty; the Guaranty fully reflects Guarantor's intentions and parol
   evidence is not required to interpret the terms of this Guaranty.  Guarantor
   hereby indemnifies and holds Lender harmless from all losses, claims,
   damages, and costs (including Lender's attorneys' fees) suffered or incurred
   by Lender as a result of any breach by Guarantor of the warranties,
   representations and agreements of this paragraph.  No alteration or amendment
   to this Guaranty shall be effective unless given in writing and signed by the
   parties sought to be charged or bound by the alteration or amendment.

   APPLICABLE LAW.  This Guaranty has been delivered to Lender and accepted by

   define the provisions of this Guaranty. If a court of competent jurisdiction
   finds any provision of this Guaranty to be invalid or unenforceable as to any

   Lender's right otherwise to demand strict compliance with that provision or
   any other provision of this Guaranty.  No prior waiver by Lender, nor any
   course of dealing between Lender and Guarantor, shall constitute a waiver of
   any of Lender's rights or of any of Guarantor's obligations as to any future

   Guaranty, the granting of such consent by Lender in any instance shall not
   constitute continuing consent to subsequent instances where such consent is

FROM JUNE 17, 1997, UNTIL PAID IN FULL.

PAYMENT.  SUBJECT TO ANY PAYMENT CHANGES RESULTING FROM CHANGES IN THE INDEX,
BORROWER WILL PAY THIS LOAN ON DEMAND, OR IF NO DEMAND IS MADE, IN 35 PRINCIPAL
PAYMENTS OF $2,641.94 EACH AND ONE FINAL PRINCIPAL AND INTEREST PAYMENT OF

SUBSEQUENT PRINCIPAL PAYMENTS ARE DUE ON THE LAST DAY OF EACH MONTH AFTER THAT.

INTEREST DUE AS OF EACH PAYMENT DATE.  BORROWER'S FIRST INTEREST PAYMENT IS DUE
JUNE 30, 1997, AND ALL SUBSEQUENT INTEREST PAYMENTS ARE DUE ON THE LAST DAY OF
EACH MONTH AFTER THAT.  BORROWER'S FINAL PAYMENT DUE JUNE 30, 2000, WILL BE FOR
ALL PRINCIPAL AND ACCRUED INTEREST NOT YET PAID.  Interest on this Note is
computed on a 365/360 simple interest basis; that is, by applying the ratio of
the annual interest rate over a year of 360 days, multiplied by the outstanding
principal balance, multiplied by the actual number of days the principal balance
is outstanding.  Borrower will pay Lender at Lender's address shown above or at
such other place as Lender may designate in writing.  Unless otherwise agreed or
required by applicable law, payments will be applied first to accrued unpaid
interest, then to principal, and any remaining amount to any unpaid collection
costs and late charges.

VARIABLE INTEREST RATE.  The interest rate on this Note is subject to change
from time to time based on changes in an index which is the Westamerica Bank
Index Rate (the "Index").  THE BANK'S INDEX RATE IS ESTABLISHED BY BANK IN ITS

more than the maximum rate allowed by applicable law.

this Note, Borrower understands that Lender is entitled to a minimum Interest
charge of $50.00. Other than Borrower's obligation to pay any minimum interest
charge, Borrower may pay all or a portion of the amount owed earlier than it is
due.  Early payments will not, unless agreed to by Lender in writing, relieve
Borrower of Borrower's obligation to continue to make payments under the payment
schedule.  Rather, they will reduce the principal balance due and may result in
Borrower's making fewer payments.

DEFAULT.  Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when

                                       6
<PAGE>
 
                     (ii) as soon as practicable thereafter, use its best
     efforts to effect such registration (including, without limitation, filing
     post-effective amendments, appropriate qualifications under applicable blue
     sky or other state securities laws, and appropriate compliance with the
     Securities Act) and as would permit and facilitate the sale and
     distribution of all or such portion of such Registrable Securities as are
     specified in such request, together with all or such portion of the
     Registrable Securities of any Holder or Holders joining in such request as
     are specified in a written request received by the Company within twenty
     (20) days after such written notice from the Company is mailed or
     delivered.

          The Company shall not be obligated to effect, or to take any action to
     effect, any such registration pursuant to this Section 1.3:

                             (A) In any particular jurisdiction in which the
     Company would be required to execute a general consent to service of
     process in effecting such registration, qualification or compliance, unless
     the Company is already subject to service in such jurisdiction and except
     as may be required by the Securities Act;

                             (B) After the Company has initiated one such
     registration pursuant to this Section 1.3(a) (counting for these purposes
     only a registration which has been declared or ordered effective and
     pursuant to which securities have been sold or a registration which has
     been withdrawn by the Holders as to which the Holders have not elected to
     bear the Registration Expenses pursuant to Section 1.5 hereof and would,
     absent such election, have been required to bear such expenses); or

                                       7
<PAGE>
 
                             (C) During the period starting from the date sixty
     (60) days prior to the Company's good faith estimate of the date of filing
     of, and ending on a date one hundred and eighty (180) days after the date
     of an underwriting agreement relating to, a Company-initiated registration;
     provided that the Company is actively employing in good faith reasonable
     efforts to cause such registration statement to become effective;

                     (D) If the IPO has not taken place, if the Initiating
     Holders do not request such offering be firmly underwritten by an
     underwriter selected by the Initiating Holders (subject to the consent of
     the Company, which consent will not be unreasonably withheld); or

                     (E) If the IPO has not taken place, if the Company and the
     Initiating Holders are unable to obtain the commitment of the underwriter
     described in clause (D) to firmly underwrite the offer.

                (b)  Subject to the foregoing clauses (A) through (E), the
     Company shall file a registration statement covering the Registrable
     Securities so requested to be registered as soon as practicable after
     receipt of the request or requests of the Initiating Holders; provided,
     however, that if (i) in the good faith judgment of the Board of Directors
     of the Company, such registration would be seriously detrimental to the
     Company, and the Board of Directors concludes, as a result, that it is
     essential to defer the filing of such registration statement at such time,
     or in the good faith judgement of the Board of Directors of the Company,
     such registration should be delayed due to the timing of the Company's
     annual audit and (ii) the Company shall furnish to such Holders a

                                       8
<PAGE>
 
     certificate signed by the President or Chief Executive Officer of the
     Company stating that in the good faith judgment of the Board of Directors
     of the Company, it would be seriously detrimental to the Company for such
     registration statement to be filed in the near future and that it is,
     therefore, essential to defer the filing of such registration statement,
     or, that such registration should be delayed due to the timing of the
     Company's annual audit, whichever is applicable, then the Company shall
     have the right to defer such filing for a collective period during any
     single calendar year of not more than one hundred and twenty (120) days
     after the receipt of the request of the Initiating Holders and, provided
     further, that the Company shall not defer its obligations in this manner
     more than twice in any twelve-month period.

          If all the Holders are allowed to include all Registrable Securities
     that such Holders requested be included in the registration statement filed
     pursuant to the request of the Initiating Holders, the registration
     statement filed pursuant to the request of the Initiating Holders may,
     subject to the provisions of this Section 1.3(b) and Section 1.11 hereof,
     include other securities of the Company, with respect to which registration
     rights have been granted, and may include securities of the Company being
     sold for the account of the Company.

          The Company shall pay the reasonable fees and disbursements of one
     counsel selected by a majority in interest of the Holders in connection
     with any registration under this Section 1.3.

                                       9
<PAGE>
 
                (c)  The right of any Holder to registration pursuant to this
     Section 1.3 shall be conditioned upon such Holders' participation in such
     underwriting and the inclusion of such Holder's Registrable Securities in
     the underwriting (unless otherwise mutually agreed by a majority in
     interest of the Initiating Holders and such Holder with respect to such
     participation and inclusion) to the extent provided herein.  A Holder may
     elect to include in such underwriting all or a part of the Registrable
     Securities he holds.

                (d)  If the Company shall request inclusion in any registration
     pursuant to this Section 1.3 of securities being sold for its own account,
     or if other persons shall request inclusion in any registration pursuant to
     this Section 1.3, and if all of the Holders are allowed to include all
     Registrable Securities that such Holders requested to be included in the
     registration statement filed pursuant to the request of the Initiating
     Holders, the Initiating Holders shall, on behalf of all Holders, offer to
     include such securities in the underwriting and may condition such offer on
     their acceptance of the further applicable provisions of this Section
     1(including this Section 1.3).  The Company shall, together with all
     Holders and other persons proposing to distribute their securities through
     such underwriting, enter into an underwriting agreement in customary form
     with the representative of the underwriter or underwriters selected for
     such underwriting by a majority in interest of the Initiating Holders
     (subject to the Company's consent, which shall not be unreasonably
     withheld).  Notwithstanding any other provision of this Section 1.3, if the
     representative of the underwriters advises the Initiating Holders in
     writing that marketing factors require a limitation on the number of shares
     to be underwritten, the number of shares to be included in the underwriting
     or registration shall be allocated as 

                                       10
<PAGE>
 
     set forth in Section 1.11 hereof. If a person who has requested inclusion
     in such registration as provided above does not agree to the terms of any
     such underwriting, such person shall be excluded therefrom by written
     notice from the Company, the underwriter or the Initiating Holders. The
     securities so excluded shall also be withdrawn from registration. Any
     Registrable Securities or other securities excluded or withdrawn from such
     underwriting shall also be withdrawn from such registration. If shares are
     so withdrawn from registration and if the number of shares to be included
     in such registration was previously reduced as a result of marketing
     factors pursuant to this Section 1.3(d), then the Company shall offer to
     all Holders who have retained rights to include securities in the
     registration the right to include additional securities in the registration
     in an aggregate amount equal to the number of shares so withdrawn, with
     such shares to be allocated among such Holders requesting additional
     inclusion in accordance with Section 1.11.

          1.4   Company Registration.
                -------------------- 

                (a)  If the Company shall determine to register any of its
     securities either for its own account or the account of a security holder
     or holders exercising their respective demand registration rights (other
     than pursuant to Section 1.3 hereof), other than a registration relating
     solely to employee benefit plans, or a registration relating to a corporate
     reorganization or other transaction under Rule 145, or a registration on
     any registration form that does not permit secondary sales, then, for a
     period commencing on the Closing Date and ending on the fifth anniversary
     thereof, the Company will:

                                       11
<PAGE>
 
                     (i)  promptly give to each Holder written notice thereof,
     subject to the limitations set forth in Section 1.4(c) hereof; and

                     (ii) use its best efforts to include in such registration
     (and any related qualification under blue sky laws or other compliance),
     except as set forth in Section 1.4(b) and (c) below, and in any
     underwriting involved therein, all the Registrable Securities specified in
     a written request or requests, made by any Holder and received by the
     Company within ten (10) days after the written notice from the Company
     described in clause (i) above is mailed or delivered by the Company. Such
     written request may specify all or a part of a Holder's Registrable
     Securities.

                (b)  If the registration of which the Company gives notice is
     for a registered public offering involving an underwriting, the Company
     shall so advise the Holders as a part of the written notice given pursuant
     to Section 1.4(a)(i). In such event, the right of any Holder to
     registration pursuant to this Section 1.4 shall be conditioned upon such
     Holder's participation in such underwriting and the inclusion of such
     Holder's Registrable Securities in the underwriting to the extent provided
     herein. All Holders proposing to distribute their securities through such
     underwriting shall (together with the Company and the holders of securities
     of the Company with registration rights to participate therein distributing
     their securities through such underwriting) enter into an underwriting
     agreement in customary form with the representative of the underwriter or
     underwriters selected by the Company.

                                       12
<PAGE>
 
                (c)  Holders may participate in a maximum of two registered
     public offerings under the provisions of this Section 1.4.

          Notwithstanding any other provision of this Section 1.4, if the
     representative of the underwriters advises the Company in writing that
     marketing factors require a limitation on the number of shares to be
     underwritten, the representative may (subject to the limitations set forth
     below) exclude all Registrable Securities from, or limit the number of
     Registrable Securities to be included in, the registration and
     underwriting. The Company shall so advise all holders of securities
     requesting registration, and the number of shares of securities that are
     entitled to be included in the registration and underwriting shall be
     allocated first to the Company for securities being sold for its own
     account and thereafter as set forth in Section 1.11. If any person does not
     agree to the terms of any such underwriting, he shall be excluded therefrom
     by written notice from the Company or the underwriter. Any Registrable
     Securities or other securities excluded or withdrawn from such underwriting
     shall be withdrawn form such registration.

          If shares are so withdrawn from the registration or if the number of
     shares of Registrable Securities to be included in such registration was
     previously reduced as a as a result of marketing factors, the Company shall
     then offer to all persons who have retained rights to include securities in
     the registration the right to include additional securities in the
     registration in an aggregate amount equal to the number of shares so
     withdrawn, with such shares to be allocated among the persons so requesting
     additional inclusion in accordance with Section 1.11 hereof.

          1.5   Expenses of Registration. All Registration Expenses incurred in
                ------------------------                            
     connection with any registration, qualification or compliance pursuant to
     Sections 1.3 and 1.4 hereof shall be borne by the Company; provided,
     however, that if the Holders bear the Registration Expenses for any
     registration proceedings begun pursuant to Section 1.3 hereof and
     subsequently withdrawn by the Holders registering shares therein, such
     registration proceeding shall not be counted as the requested registration
     pursuant to Section 1.3 hereof. Conversely, if the Company bears the
     Registration Expenses for any registration proceedings begun pursuant to
     Section 1.3 hereof, and subsequently withdrawn by the Holders registering
     shares therein, other than a withdrawal based on material adverse
     information, as described below, such registration proceeding shall be
     counted as a requested registration pursuant to Section 1.3 hereof.
     Furthermore, in the event that a withdrawal by the Holders is based upon
     material adverse information relating to the Company that is different from
     the information known or available (upon request from the Company or
     otherwise) to the Holders requesting registration at the time of their
     request for registration under Section 1.3, such registration shall not be
     treated as a counted registration for purposes of Section 1.3, even though
     the Holders do not bear the Registration Expenses for such registration.
     All Selling Expenses relating to securities so registered shall be borne by
     the Holders of such securities pro rata on the basis of the number of
     shares of securities so registered on their behalf, as shall any other
     expenses in connection with the registration to be borne by the Holders of
     such securities.

          1.6   Indemnification.  In the event any Registrable Securities are
                ---------------                                              
included in a registration statement under Sections 1.3 or 1.4:

<PAGE>
 
                (a)  By the Company. To the extent permitted by law, the Company
                     --------------    
will indemnify and hold harmless each Holder, the partners, officers and
directors of each Holder, any underwriter for such Holder and each person, if
any, who controls such Holder or underwriter within the meaning of the
Securities Act or the Exchange Act against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation"):

                     (i)   any untrue statement or alleged untrue statement of a
     material fact contained in such registration statement, including any
     preliminary prospectus or final prospectus contained therein or any
     amendments or supplements thereto;

                     (ii)  the omission or alleged omission to state therein a
     material fact required to be stated therein, or necessary to make the
     statements therein not misleading, or

                     (iii) any Violation or alleged Violation by the Company of
     the Securities Act, the Exchange Act, any federal or state securities law
     or any rule or regulation promulgated under the Securities Act, the
     Exchange Act or any federal or state securities law in connection with the
     offering covered by such registration statement;

                                       15
<PAGE>
 
and the Company will reimburse each such Holder, partner, officer or director,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this subsection 1.6(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable in any such
case for any such loss, claim, damage, liability or action to the extent that it
arises out of or in based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by such Holder, partner, officer, director, underwriter
or controlling person of such Holder.

                (b)  By Selling Holders. To the extent permitted by law, each
selling Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company within the meaning of the Securities
Act, any underwriter and any other Holder selling securities under such
registration statement or any of such other Holders' partners, directors or
officers or any person who controls such underwriter or other Holder within the
meaning of the Securities Act or the Exchange Act, against any losses, claims,
damages or liabilities (joint or several) to which the Company or any such
director, officer, controlling person, underwriter or other such Holder, partner
or director, officer or controlling person of such underwriter or other Holder
may become subject under the Securities Act, the Exchange Act or other federal
or state law, insofar as such losses, claims, damages or liabilities (or actions
in respect thereto) arise out of or are

                                       16
<PAGE>
 
based upon any Violation, in each case to the extent (and only to the extent)
that such Violation occurs in reliance upon and in conformity with written
information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or other Holder, partner, officer, director or controlling
person of such other Holder or underwriter in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection 1.6(b) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability or
action if such settlement is effected without the consent of the Holder, which
consent shall not be unreasonably withheld; and provided further that the total
amounts payable in indemnity by a Holder under this Section 1.6(b) in respect of
any Violation shall not exceed the gross proceeds received by such Holder in the
registered offering out of which such Violation arises.

                (c)  Notice. Promptly after receipt by an indemnified party
under this Section 1.6 of notice of the commencement of any action (including
any governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 1.6,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by

                                       17
<PAGE>
 
the counsel retained by the indemnifying party would be inappropriate due to an
actual conflict of interest between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, if prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 1.6, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 1.6.

                (d)  Defect Eliminated in Final Prospectus. The foregoing
indemnity agreements of the Company and Holders are subject to the condition
that, insofar as they relate to any Violation made in a preliminary prospectus
but eliminated or remedied in the amended prospectus on file with the SEC at the
time the registration statement in question becomes effective or the amended
prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "Final
Prospectus"), such indemnity agreement shall not inure to the benefit of any
indemnified party if a copy of the Final Prospectus was furnished to the
indemnified party and the indemnified party was required to, but did not,
furnish the Final Prospectus to the person asserting the loss, liability, claim
or damage at or prior to the time such action is required by the Securities Act.

                (e)  Contribution.  In order to provide for just and equitable
                     ------------                                             
contribution to joint liability under the Securities Act in any case in which
either (i) any Holder exercising rights under this Agreement, or any controlling
person of any such Holder, makes a claim for indemnification pursuant to this
Section 1.6 but it is judicially determined (by the entry 

                                       18
<PAGE>
 
of a final judgment or decree by a court of competent jurisdiction and the
expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 1.6 provides for indemnification in such case, or (ii)
contribution under the Securities Act may be required on the part of any such
selling Holder or any such controlling person in circumstances for which
indemnification is provided under this Section 1.6; then, and in each such case,
the Company and such Holder will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from
others) in such proportion as is appropriate to reflect the relative benefits
and the relative fault of the Company on the one hand and the Holders on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the Holders shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of material fact related to information supplied by the Company
or the Stockholders and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The relative benefits received by a Holder or the Company shall be that portion
represented by the percentage that the public offering price of its Registrable
Securities offered by and sold under the registration statement bears to the
public offering price of all securities offered by and sold under such
registration statement; provided, however, that, in any such case, (A) no such
Holder will be required to contribute more than the gross proceeds received by
such holder from all such Registrable Securities offered and sold by such Holder
pursuant to such registration statement; and (B) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be 

                                       19
<PAGE>
 
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

                (f)  Survival. The obligations of the Company and Holders under
                     -------- 
this Section 1.6 shall survive the completion of any offering of Registrable
Securities pursuant to a registration statement, and otherwise.

          1.7   Information by Holder.  Each Holder of Registrable Securities
                ---------------------                                        
shall furnish to the Company such information regarding such Holder and the
distribution proposed by such Holder as the Company may reasonably request in
writing and as shall be reasonably required in connection with any registration,
qualification, or compliance referred to in this Section 1.

          1.8   Transfer or Assignment of Registration Rights.  The rights to
                ---------------------------------------------                
cause the Company to register securities granted to a Holder by the Company
under this Section 1 may be transferred or assigned by a Holder to a transferee
or assignee who acquires at least the lesser of (i) all of such Holder's
Registrable Securities or (ii) 25,000 shares of Registrable Securities (as
presently constituted and subject to subsequent adjustments for stock splits,
stock dividends, reverse splits and the like), provided that the Company is
given written notice at the time of or within reasonable time after said
transfer or assignment, stating the name and address of the transferee or
assignee and identifying the securities with respect to which such registration
rights are being transferred or assigned, and, provided further, that the
transferee or assignee of such rights assumes in writing the obligations of such
Holder under this Section 1.

          1.9   "Market Stand-Off" Agreement.  Each Holder hereby agrees that it
                 ---------------------------                                    
shall not, to the extent requested by the Company or an underwriter of
securities of the Company, sell or otherwise transfer or dispose of any
Registrable Securities or other shares of stock of the Company then owned by
such Holder (other than to donees or partners of the Holder who agree to be
similarly bound) for up to 180 days following the effective date of a
registration statement of the Company filed under the Securities Act; provided,
however, that:

                (a)  such agreement shall be applicable only to the first such
registration statement of the Company which covers securities to be sold on its
behalf to the public in an underwritten offering but not to Registrable
Securities sold pursuant to such registration statement; and

                (b)  all executive officers and directors of the Company then
holding Common Stock of the Company enter into similar agreements.

     In order to enforce the foregoing covenant, the Company shall have the
right to place restrictive legends on the certificates representing the shares
subject to this Section and to impose stop transfer instructions with respect to
the Registrable Securities and such other shares of stock of each Holder (and
the shares or securities of every other person subject to the foregoing
restriction) until the end of such period. Each Holder further agrees that the
provisions of this Section 1.9 shall be applicable to any transferee of shares
from such Holder and such transferee as a condition of the transfer shall agree
to this Section 1.9 and that this Section 1.9 shall be applicable to all
subsequent transferees.

          1.10  Rule 144 Reporting.  With a view to making available the
                ------------------                                      
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Registrable Securities to the public without
registration, after such time as a public market exists for the Common Stock of
the Company, the Company agrees to:

                (a)  Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date of the first registration under the Securities Act
filed by the Company for an offering of its securities to the general public;

                (b)  Use its reasonable best efforts to file with the Commission
in a timely manner all reports and other documents required of the Company under
the Securities Act and the Exchange Act (at any time after it has become subject
to such reporting requirements); and

                (c)  So long as a Holder owns any Registrable Securities, to
furnish to the Holder forthwith upon request therefrom a written statement by
the Company as to its compliance with the reporting requirements of Rule 144 (at
any time after 90 days after the effective date of the first registration
statement filed by the Company for an offering of its securities to the general
public), and of the Securities Act and the Exchange Act (at any time after it
has become subject to the reporting requirements of the Exchange Act), a copy of
the most recent annual or quarterly report of the Company, and such other
reports and documents of the Company as a Holder may reasonably request in
availing itself of any rule or regulation of

                                       22
<PAGE>
 
the Commission allowing a Holder to sell any such securities without
registration (at any time after the Company has become subject to the reporting
requirements of the Exchange Act).

          1.11  Allocation of Registration Opportunities.  In any circumstance
                ----------------------------------------                      
in which all of the Registrable Securities and other securities of the Company
with registration rights (the "Other Shares") requested to be included in a
registration on behalf of the Holders or other selling stockholders cannot be so
included as a result of limitations of the aggregate number of shares of
Registrable Securities and Other Shares that may be so included, the number of
shares of Registrable Securities and Other Shares that may be so included shall
be allocated among the Holders and other selling stockholders requesting
inclusion of shares pro rata on the basis of the number of shares of Registrable
Securities and Other Shares that would be held by such Holders and other selling
stockholders, assuming conversion; provided, however, that such allocation shall
not operate to reduce the aggregate number of Registrable Securities and Other
Shares to be included in such registration, if any Holder or other selling
stockholder does not request inclusion of the maximum number of shares of
Registrable Securities and Other Shares allocated to him pursuant to the above-
described procedure, the remaining portion of his allocation shall be
reallocated among those requesting Holders and other selling stockholders whose
allocations did not satisfy their requests pro rata on the basis of the number
of shares of Registrable Securities and Other Shares which would be held by such
Holders and other selling stockholders, assuming conversion, and this procedure
shall be repeated until all of the shares of Registrable Securities and Other
Shares which may be included in the registration on behalf of the Holders and
other selling stockholders have been so allocated; and provided further, with
respect to the registration provided in Section 1.3(a), the number of shares of
Registrable Securities that may be so 

                                       23
<PAGE>
 
included shall be allocated: (a) First, among the Holders requesting inclusion
of shares pro rata on the basis of the number of shares of Registrable
Securities that would be held by such Holders, assuming conversion; and (b)
Second, if all of the Holders requesting inclusion are able to include all of
the shares requested to be included by such Holders in such offering, then, the
remainder of the shares that may be so included shall be allocated among the
other selling stockholders requesting inclusion of shares pro rata on the basis
of the number of Other Shares that would be held by such other selling
stockholders, assuming conversion. The Company shall not limit the number of
Registrable Securities to be included in a registration pursuant to this
Agreement in order to include shares held by stockholders with no registration
rights.

          1.12  Delay of Registration.  No Holder shall have any right to take
                ---------------------                                         
any action to restrain, enjoin, or otherwise delay any registration as the
result of any controversy that may arise with respect to the interpretation or
implementation of this Section 1.

          1.13  Termination of Registration Rights.
                ---------------------------------- 

                (a)  No Holder shall be entitled to exercise any right provided
in Section 1.3: (i) prior to the earlier of (A) three (3) years from the Closing
Date or (B) one (1) year after the IPO, and (ii) after the Company has initiated
one such registration pursuant to Section 1.3 (counting for these purposes only
a registration which has been declared effective and pursuant to which
securities have been sold or a registration which has been withdrawn by the
Holders as to which the Holders have not elected to bear Registration Expenses
pursuant to Section 1.5 hereof and would, absent such election, have been
required to bear such expenses).

<PAGE>
 
                (b)  No Holder shall be entitled to exercise any right provided
in Section 1.4 after the first to occur of : (i) five (5) years following the
Closing Date, and (ii) after Holders have participated in two such registrations
pursuant to Section 1.4.

     2.   INVESTOR CONFIDENTIALITY.
          ------------------------ 

          Each Investor hereby agrees to safeguard against disclosure to third
parties all confidential information concerning the business of the Company that
may be disclosed to such Investor by reason of such Investor's access to the
books, records, properties or personnel of the Company before or after the date
hereof (collectively, "Company Confidential Information") by using reasonable
secrecy measures and in no event less than the same degree of care as such
Investor uses for such Investor's own similar proprietary information.  However,
an Investor shall not be obligated to maintain any such Company Confidential
Information in confidence to the extent that: (i) the Company Confidential
Information is or becomes public knowledge other than through the fault of such
Investor; (ii) the Company Confidential Information is or becomes available on
an unrestricted basis to such Investor from a source other than the Company; or
(iii) the Company Confidential Information is required to be disclosed by such
Investor, under a court order or governmental action, provided that such
Investor provides not less than 10 days' prior written notification to the
Company of such obligation and seeks, or allows the Company to seek, an
appropriate protective order, and provided further that disclosure solely
pursuant to this clause (iii) shall not release an Investor from such Investor's
obligation to maintain confidentiality.

all prepared in accordance with generally accepted accounting principles and
practices and audited by the Company's independent certified public accountants;

                (b)  Quarterly Reports.  Furnish to such Investor, as soon as
                     -----------------

unaudited consolidated financial statements, including an unaudited consolidated
Balance Sheet, an unaudited consolidated Statement of Income and an unaudited

Section 3.1 will terminate upon the earliest of (i) the closing of the Company's

                ----------                                                  
exercised reasonable care and prudence under the circumstances in connection

     3.   Representations and Warranties of the Investors.  Each Investor
          -----------------------------------------------                
severally represents and warrants to the Company as follows:

          3.1   Authorization.  Such Investor has full power and authority to
                -------------                                                
enter into this Agreement and the Investors' Rights Agreement, and each such
Agreement constitutes its valid and legally binding obligation, enforceable in
accordance with its terms.

          3.2   Private Offering.  Each Investor understands and acknowledges
                ----------------                                             
that the offering of the Shares pursuant to this Agreement will not be
registered under the Securities Act on the grounds that the offering and sale of
securities contemplated by this Agreement are exempt from registration pursuant
to Section 4(2) of the Securities Act of 1933, as amended (the "Securities
Act"), and Rule 506 of Regulation D promulgated thereunder, and that the
Company's reliance upon such exemption is predicated upon the truth and accuracy
of each Investor's representations set forth in this Agreement and the Offeree
Questionnaire, a copy of which is attached hereto as Exhibit C.
                                                     --------- 

          3.3   Purchase Entirely for Own Account.  This Agreement is made with
                ---------------------------------                              
each Investor in reliance upon such Investor's representation to the Company,
which by such Investor's execution of this Agreement such Investor hereby
confirms, that the Shares to be purchased by such Investor and the Class B
Common Stock issuable upon conversion thereof will be acquired for investment
for such Investor's own account, not as a nominee or agent, and 

                                       11
<PAGE>
 
not with a view to the resale or distribution of any part thereof, and that such
Investor has no present intention of selling, granting any participation in, or
otherwise distributing the same. By executing this Agreement, each Investor
further represents that such Investor does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer or grant
participations to such person or to any third person with respect to any of the
Shares.

          3.4   Restricted Securities.   Each Investor understands that the
                ---------------------                                      
Shares (and any Class B Common Stock issued upon conversion thereof) may not be
sold, transferred, or otherwise disposed of without registration under the
Securities Act or an exemption therefrom, and that in the absence of an
effective registration statement covering the Shares (or the Class B Common
Stock issued on conversion thereof) must be held indefinitely.  In particular,
each Investor is aware that the Shares (and any Class B Common Stock issuable
upon conversion thereof) may not be sold pursuant to Rule 144 promulgated under
the Securities Act unless all of the conditions of the Rule are met.  Among the
conditions for use of Rule 144 may be the availability of current information to
the public about the Company.  Such information is not now available and the
Company may or may not make such information available in the future.

          3.5   Qualifications.   Each Investor represents that: (i) such
                --------------                                           
Investor has such knowledge and experience in financial and business matters as
to be capable of evaluating the merits and risks of such Investor's prospective
investment in the Shares; (ii) such Investor has received all the information it
has requested from the Company and considers necessary or appropriate for
deciding whether to purchase the Shares; (iii) such Investor has the ability to
bear the economic risks of such Investor's prospective investment; (iv) such
Investor is able, without materially impairing its financial condition, to hold
the Shares for an indefinite period of time 

                                       12
<PAGE>
 
and to suffer complete loss on its investment; and (v) such Investor is an
"accredited investor" within the meaning of Rule 501 of Regulation D under the
Securities Act. Each Investor understands that the Shares are not (and any Class
B Common Stock issued upon conversion thereof may not be) registered under the
Securities Act on the ground that the sale provided for in this Agreement and
the issuance of the securities hereunder is exempt from registration under Rule
506 of Regulation D, promulgated under Section 4(2) of the Securities Act. The
Company's reliance on such exemption is predicated upon the Investors'
representations set forth herein and in the Offeree Questionnaire, a copy of
which is attached hereto as Exhibit C . Each Investor realizes that the basis
                            ---------        
for the exemption may not be present if, notwithstanding such representations,
the Investor has in mind merely acquiring the Shares for a fixed or determinable
period in the future, or for a market rise, or for sale if the market does not
rise. No Investor has any such intention.

     4.   Legends.
          ------- 

          (a)  All certificates for the Shares shall bear the following legend:

                    "The Shares represented hereby have not been registered
               under the Securities Act of 1933, as amended, and may not be sold
               or transferred, assigned, pledged or hypothecated unless and
               until registered under such Act or unless the Company has
               received an opinion of counsel or other evidence, satisfactory to
               the Company and its counsel, that such registration is not
               required."

          (b)  The certificates evidencing the Shares shall also bear any legend
required by the Commissioner of Corporations of the State of California or
required pursuant to any state, local or foreign law governing such securities.

                            TIER TECHNOLOGIES, INC.

                         EMPLOYEE STOCK PURCHASE PLAN
                         ----------------------------

     
     I.   PURPOSE OF THE PLAN

          This Employee Stock Purchase Plan is intended to promote the interests
of Tier Technologies, Inc. by providing eligible employees with the opportunity
to acquire a proprietary interest in the Corporation through participation in a
payroll-deduction based employee stock purchase plan.

          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.
      
     II.  ADMINISTRATION OF THE PLAN

          The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423.  Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

     III. STOCK SUBJECT TO PLAN

          A.   The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Class B Common Stock, including shares of
Class B Common Stock purchased on the open market. The maximum number of shares
of Class B Common Stock which may be issued over the term of the Plan shall not
exceed 100,000 shares.

          B.   Should any change be made to the Class B Common Stock by reason
of any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Class B Common
Stock as a class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and class of securities
issuable under the Plan, (ii) the maximum number and class of securities
purchasable per Participant on any one Purchase Date and (iii) the number and
class of securities and the price per share in effect under each outstanding
purchase right in order to prevent the dilution or enlargement of benefits
thereunder.

     IV.  PURCHASE PERIODS

          A.   Shares of Class B Common Stock shall be offered for purchase
under the Plan through a series of successive Purchase Periods until such time
as (i) the maximum number of shares of Class B Common Stock available for
issuance under the Plan shall have been purchased or (ii) the Plan shall have
been sooner terminated.
<PAGE>
 
          B.   Each Purchase Period shall be six (6) months in duration, unless
otherwise determined by the Plan Administrator prior to the start date of the
Purchase Period, and provided that the initial Purchase Period shall commence at
the Effective Time and shall terminate on the last business day in May 1998.
The next Purchase Period shall commence on the first business day in June 1998
and shall terminate on the last business day in November 1998; subsequent
Purchase Periods shall commence every six (6) months thereafter on the first
business day in December and June each year, unless otherwise designated by the
Plan Administrator.  The Plan Administrator shall have complete discretion to
change the start date and the duration of a Purchase Period, provided Eligible
Employees are notified prior to the start date of any Purchase Period for which
such change is to be effective and provided, further, that no Purchase Period
shall have a duration exceeding twenty-seven (27) months.

     V.   ELIGIBILITY

          A.   Each Eligible Employee of a Participating Corporation shall be
eligible to participate in the Plan in accordance with the following provisions:

               (i)    An individual who is an Eligible Employee on the start
date of any Purchase Period under the Plan shall be eligible to commence
participation in that Purchase Period on such start date.

               (ii)   An individual who first becomes an Eligible Employee after
the start date of any Purchase Period will not be eligible to commence
participation under the Plan until the start date of the next Purchase Period on
which he/she remains an Eligible Employee.

          B.   To participate in the Plan for a particular Purchase Period, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (which may include a stock purchase agreement and a payroll
deduction authorization form) and file such forms with the Plan Administrator
(or its designate) on or before the start date for the Purchase Period.

     VI.  PAYROLL DEDUCTIONS

          A.   The payroll deduction authorized by the Participant for purposes
of acquiring shares of Class B Common Stock under the Plan may be any multiple
of one percent (1%) of the Cash Compensation paid to the Participant during that
Purchase Period, up to a maximum of ten percent (10%). The deduction rate so
authorized shall continue in effect for the remainder of the Purchase Period,
except to the extent such rate is changed in accordance with the following
guidelines:

               (i)  The Participant may, at any time during the Purchase Period,
reduce his or her rate of payroll deduction to become effective as soon as

Participant may not, however, effect more than one (1) such reduction per
Purchase Period.

<PAGE>
 
               (ii)  The Participant may, prior to the commencement of any new
Purchase Period, increase the rate of his or her payroll deduction by filing the
appropriate form with the Plan Administrator. The new rate (which may not exceed
the ten percent (10%) maximum) shall become effective as of the start date of
the Purchase Period following the filing of such form.

          B.   Payroll deductions shall begin on the first pay day following the
start date for the Purchase Period and shall (unless sooner terminated by the
Participant) continue through the pay day ending with or immediately prior to
the last day of that Purchase Period. The amounts so collected shall be credited
to the Participant's book account under the Plan, but no interest shall be paid
on the balance from time to time outstanding in such account. The amounts
collected from the Participant shall not be held in any segregated account or
trust fund and may be commingled with the general assets of the Corporation and
used for general corporate purposes.

          C.   Payroll deductions shall automatically cease upon the termination
of the Participant's purchase right in accordance with the provisions of the
Plan.

          D.   The Participant's acquisition of Class B Common Stock under the
Plan on any Purchase Date shall neither limit nor require the Participant's
acquisition of Class B Common Stock on any subsequent Purchase Date.

     VII. PURCHASE RIGHTS

          A.   GRANT OF PURCHASE RIGHT.  A Participant shall be granted a
               -----------------------                                   
separate purchase right for each Purchase Period in which he or she
participates. The purchase right shall be granted on the start date of the
Purchase Period and shall provide the Participant with the right to purchase
shares of Class B Common Stock, upon the terms set forth below. The purchase
right shall continue until the end of the Purchase Period, and shall be
automatically exercised on the last business day of the respective Purchase
Period each year (the last business day of May and the last business day of
November) or such other date as may be selected by the Plan Administrator as the
ending date for the Purchase Period). The Participant shall execute a stock
purchase agreement embodying such terms and such other provisions (not
inconsistent with the Plan) as the Plan Administrator may deem advisable.

          Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)), or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any Corporate Affiliate.

          B.   EXERCISE OF THE PURCHASE RIGHT.  Each purchase right shall be
               ------------------------------                               
automatically exercised on the respective Purchase Date, and shares of Class B
Common Stock shall accordingly be purchased on behalf of each Participant (other
than any Participant whose payroll deductions have previously been refunded in
accordance with the Termination of Purchase Right provisions below) on each such
Purchase Date.  The purchase shall be effected by applying the Participant's
payroll deductions for the Purchase Period ending on such Purchase 

                                       3
<PAGE>
 
Date (together with any carryover deductions from the preceding Purchase Period)
to the purchase of whole shares of Class B Common Stock (subject to the
limitation on the maximum number of shares purchasable per Participant on any
one Purchase Date) at the purchase price in effect for the Participant for that
Purchase Date.

          C.   PURCHASE PRICE.  The purchase price per share at which Class B
               --------------                                                
Common Stock will be purchased on the Participant's behalf on each Purchase Date
shall be equal to eighty-five percent (85%) of the lower of (i) the Fair Market
Value per share of Class B Common Stock on the start date for that Purchase
Period or (ii) the Fair Market Value per share of Class B Common Stock on that
Purchase Date.

          D.   NUMBER OF PURCHASABLE SHARES.  The number of shares of Class B
               ----------------------------                                  
Common Stock purchasable by a Participant on each Purchase Date shall be the
number of whole shares obtained by dividing the amount collected from the
Participant through payroll deductions during the Purchase Period ending with
that Purchase Date (together with any carryover deductions from the preceding
Purchase Period) by the purchase price in effect for the Participant for that
Purchase Date.  However, the maximum number of shares of Class B Common Stock
purchasable per Participant on any Purchase Date shall not exceed five hundred
(500) shares, subject to periodic adjustments in the event of certain changes in
the Corporation's capitalization.

          E.   EXCESS PAYROLL DEDUCTIONS.  Any payroll deductions not applied to
               -------------------------                                        
the purchase of shares of Class B Common Stock on any Purchase Date because they
are not sufficient to purchase a whole share of Class B Common Stock shall be
held for the purchase of Class B Common Stock on the next Purchase Date, or at
the option of the Plan Administrator, may be used to buy fractional shares.
However, any payroll deductions not applied to the purchase of Class B Common
Stock by reason of the limitation on the maximum number of shares purchasable by
the Participant on the Purchase Date shall be promptly refunded, without
interest.

          F.   TERMINATION OF PURCHASE RIGHT.  The following provisions shall
               -----------------------------                                 
govern the termination of outstanding purchase rights:

               (i)  A Participant may, at any time prior to the next Purchase
Date , terminate his or her outstanding purchase right by filing the appropriate
form with the Plan Administrator (or its designate), and no further payroll
deductions shall be collected from the Participant with respect to the
terminated purchase right. Any payroll deductions collected during the Purchase
Period in which such termination occurs shall, at the Participant's election, be
immediately refunded, without interest, or held for the purchase of shares on
the next Purchase Date. If no such election is made at the time such purchase
right is terminated, then the payroll deductions collected with respect to the
terminated right shall be refunded as soon as possible, without interest.

               (ii)  The termination of such purchase right shall be
irrevocable, and the Participant may not subsequently rejoin the Purchase Period
for which the terminated purchase right was granted. In order to resume
participation in any subsequent Purchase Period, such 

                                       4
<PAGE>
 
individual must re-enroll in the Plan (by making a timely filing of the
prescribed enrollment forms) on or before the start date for that Purchase
Period.

               (iii) Should the Participant cease to remain an Eligible Employee
for any reason (including death, disability or change in status) while his or
her purchase right remains outstanding, then that purchase right shall
immediately terminate, and all of the Participant's payroll deductions for the
Purchase Period in which the purchase right so terminates shall be immediately
refunded. However, should the Participant cease to remain in active service by
reason of an approved unpaid leave of absence, then the Participant shall have
the election, exercisable up until the last business day of the Purchase Period
in which such leave commences, to (a) withdraw all the funds in the
Participant's payroll account at the time of the commencement of such leave or
(b) have such funds held for the purchase of shares at the end of such Purchase
Period. In no event, however, shall any further payroll deductions be added to
the Participant's account during such leave. Upon the Participant's return to
active service, his or her payroll deductions under the Plan shall automatically
resume at the rate in effect at the time the leave began, provided the
Participant returns to service prior to the expiration date of the Purchase
Period in which such leave began.

          G.   CORPORATE TRANSACTION.  Each outstanding purchase right shall
               ---------------------                                        
automatically be exercised, immediately prior to the effective date of any
Corporate Transaction, by applying the payroll deductions of each Participant
for the Purchase Period in which such Corporate Transaction occurs to the
purchase of whole shares of Class B Common Stock at a purchase price per share
equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value per
share of Class B Common Stock on the start date for the Purchase Period in which
such Corporate Transaction occurs or (ii) the Fair Market Value per share of
Class B Common Stock immediately prior to the effective date of such Corporate
Transaction.  However, the applicable limitation on the number of shares of
Class B Common Stock purchasable per Participant shall continue to apply to any
such purchase.

          The Corporation shall use its best efforts to provide at least ten
(10) days prior written notice of the occurrence of any Corporate Transaction,
and Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Corporate Transaction.

          H.   PRORATION OF PURCHASE RIGHTS.  Should the total number of shares
               ----------------------------                                    
of Class B Common Stock which are to be purchased pursuant to outstanding
purchase rights on any particular date exceed the number of shares then
available for issuance under the Plan, the Plan Administrator shall either (i)
make a pro-rata allocation of the available shares on a uniform and
nondiscriminatory basis, in which case the payroll deductions of each
Participant, to the extent in excess of the aggregate purchase price payable for
the Class B Common Stock pro-rated to such individual, shall be refunded,
without interest, or (ii) increase the number of shares then available for
issuance under the Plan, subject to shareholder approval, by an amount at least
sufficient to permit the purchase of all shares which are to be purchased
pursuant to outstanding purchase rights on such date

                                       5
<PAGE>
 
          I.   ASSIGNABILITY.  During the Participant's lifetime, the purchase
               -------------                                                  
right shall be exercisable only by the Participant and shall not be assignable
or transferable by the Participant.

          J.   SHAREHOLDER RIGHTS.  A Participant shall have no shareholder
               ------------------                                          
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

    VIII. ACCRUAL LIMITATIONS

          A.   No Participant shall be entitled to accrue rights to acquire
Class B Common Stock pursuant to any purchase right outstanding under this Plan
if and to the extent such accrual, when aggregated with (i) rights to purchase
Class B Common Stock accrued under any other purchase right granted under this
Plan and (ii) similar rights accrued under other employee stock purchase plans
(within the meaning of Code Section 423) of the Corporation or any Corporate
Affiliate, would otherwise permit such Participant to purchase more than twenty-
five thousand dollars ($25,000) worth of stock of the Corporation or any
Corporate Affiliate (determined on the basis of the Fair Market Value of such
stock on the date or dates such rights are granted) for each calendar year such
rights are at any time outstanding.

          B.   For purposes of applying such accrual limitations, the following
provisions shall be in effect:

               (i)  The right to acquire Class B Common Stock under each
outstanding purchase right shall accrue on each successive Purchase Date.

               (ii)  No right to acquire Class B Common Stock under any
outstanding purchase right shall accrue to the extent the Participant has
already accrued in the same calendar year the right to acquire Class B Common
Stock under one or more other purchase rights in an amount equal to twenty-five
thousand dollars ($25,000) worth of Class B Common Stock (determined on the
basis of the Fair Market Value of such stock on the date or dates of grant) for
each calendar year such rights were at any time outstanding.

          C.   If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Period, then the payroll
deductions which the Participant made during that Purchase Period with respect
to such purchase right shall be promptly refunded, without interest.

          D.   In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

Participant on any one Purchase Date, except for permissible adjustments in the
event of certain changes in the Corporation's capitalization as provided in
Section III.B hereof, (ii) alter the purchase price formula so as to reduce the

the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to

cause.

     SECTION 2.1.  LINE OF CREDIT.

     (a)  Line of Credit.  Subject to the terms and conditions of this

Agreement, Bank hereby agrees to make advances to Borrower under the Line of
Credit from time to time up to and including December 31, 1998, not to exceed at

Line of Credit shall be evidenced by the Line of Credit Note, all terms of which
are incorporated herein by this reference.

Credit, to a maximum of the principal amount set forth above, shall not at any

Accounts Receivable, as determined by Bank upon receipt and review of all

contingencies

which Bank reasonably believes may affect payment of any portion of the
Companies' accounts, Bank, in its reasonable discretion, may reduce the
foregoing advance rate against Eligible Accounts Receivable to a percentage
appropriate to reflect such additional dilution and/or establish additional

greater than two (2) years and subject to such other terms and conditions as
Bank shall determine at the time requested, and shall be evidenced by an
Equipment Lease in form and substance satisfactory to Bank, in its reasonable
discretion. The amount financed under each Equipment Lease shall be reserved

all principal, interest and fees due under each Credit by charging Borrower's
demand deposit account number 4584-477244 with Bank, or any other demand deposit

adverse effect on such Company.

     SECTION 3.2.   AUTHORIZATION AND VALIDITY.  The Loan Documents have been
duly authorized, and upon their execution and delivery in accordance with the
provisions hereof will constitute legal, valid and binding agreements and

general principles of equity and the effect of bankruptcy, insolvency or similar
laws.

     SECTION 3.3.   NO VIOLATION.  The execution, delivery and performance by
each Company of its respective Loan Documents (a) do not violate any provision
of any law or regulation, (b) contravene any provision of the Articles or
Certificate of Incorporation, Certificate of Registration, By-Laws or other
organizational documents of such Company, or (c) result in any breach of or
default under any contract, obligation, indenture or other instrument to which
any Company is a party or by which any Company may be bound, where such breach
or default gives rise to the right of acceleration of such contract, obligation,
indenture or instrument.

     SECTION 3.4.   LITIGATION.  There are no pending, or to the best of
Borrower's knowledge threatened, actions, claims, investigations, suits or

pending assessments or adjustments of any Company's income tax payable with
respect to any year.

     SECTION 8.8.   SEVERABILITY OF PROVISIONS.  If any provision of this

without invalidating the remainder of such provision or any remaining provisions
of this Agreement.

     SECTION 8.9.   COUNTERPARTS.  This Agreement may be executed in any number

     SECTION 8.11.  ARBITRATION.

     (a)  Arbitration.  Upon the demand of any party, any Dispute shall be
          -----------                                                     
resolved by binding arbitration in accordance with the terms of this Agreement.
A "Dispute" shall mean any action, dispute, claim or controversy of any kind,
whether in contract or tort, statutory or common law, legal or equitable, now
existing or hereafter arising under or in connection with, or in any way
pertaining to, any of the Loan Documents, or any past, present or future
extensions of credit and other activities, transactions or obligations of any
kind related directly or indirectly to any of the Loan Documents, including
without limitation, any of the foregoing arising in connection with the exercise
of any self-help, ancillary or other remedies pursuant to any of the Loan
Documents.  Any party may by summary proceedings bring an action in court to
compel arbitration of a Dispute.  Any party who fails or refuses to submit to
arbitration following a lawful demand by any other party shall bear all costs
and expenses incurred by such other party in compelling arbitration of any
Dispute.

     (b)  Governing Rules.  Arbitration proceedings shall be administered by the
          ---------------                                                       
American Arbitration Association ("AAA") or such other administrator as the
parties shall mutually agree upon in accordance with the AAA Commercial
Arbitration Rules.  All Disputes submitted to arbitration shall be resolved in
accordance with the Federal Arbitration Act (Title 9 of the United States Code),
notwithstanding any conflicting choice of law provision in any of the Loan
Documents.  The arbitration shall be conducted at a location in California
selected by the AAA or other 

                                      -21-
<PAGE>
 
administrator. If there is any inconsistency between the terms hereof and any
such rules, the terms and procedures set forth herein shall control. All
statutes of limitation applicable to any Dispute shall apply to any arbitration
proceeding. All discovery activities shall be expressly limited to matters
directly relevant to the Dispute being arbitrated. Judgment upon any award
rendered in an arbitration may be entered in any court having jurisdiction;
provided however, that nothing contained herein shall be deemed to be a waiver
by any party that is a bank of the protections afforded to it under 12 U.S.C.
(S)91 or any similar applicable state law.

     (c)  No Waiver; Provisional Remedies, Self-Help and Foreclosure.  No
          ----------------------------------------------------------     
provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding.  The exercise of any such remedy shall not waive the right of any
party to compel arbitration or reference hereunder.

     (d)  Arbitrator Qualifications and Powers; Awards.  Arbitrators must be
          --------------------------------------------                      
active members of the California State Bar or retired judges of the state or
federal judiciary of California, with expertise in the substantive laws
applicable to the subject matter of the Dispute.  Arbitrators are empowered to
resolve Disputes by summary rulings in response to motions filed prior to the
final arbitration hearing.  Arbitrators (i) shall resolve all Disputes in
accordance with the substantive law of the state of California, (ii) may grant
any remedy or relief that a court of the state of California could order or
grant within the scope hereof and such ancillary relief as is necessary to make
effective any award, (iii) shall have the power to award recovery of all costs
and fees, to order discovery, to impose sanctions and to take such other actions
as they deem necessary to the same extent a judge could pursuant to the Federal
Rules of Civil Procedure, the California Rules of Civil Procedure or other
applicable law, and (iv) shall not have the power to make any award which is not
supported by substantial evidence or which is based on legal error.  All Dispute
shall be decided by a single arbitrator.

     (e)  Real Property Collateral; Judicial Reference. Notwithstanding anything
          --------------------------------------------                  
herein to the contrary, no Dispute shall be submitted to arbitration if the
Dispute concerns indebtedness secured directly or indirectly, in whole or in
part, by any real property unless (i) the holder of the mortgage, lien or
security interest specifically elects in writing to proceed with the
arbitration, or (ii) all parties to the arbitration waive any 

                                      -22-
<PAGE>
 
rights or benefits that might accrue to them by virtue of the single action rule
statute of California, thereby agreeing that all indebtedness and obligations of
the parties, and all mortgages, liens and security interests securing such
indebtedness and obligations, shall remain fully valid and enforceable. If any
such Dispute is not submitted to arbitration, the Dispute shall be referred to a
referee in accordance with California Code of Civil Procedure Section 638 et
seq., and this general reference agreement is intended to be specifically
enforceable in accordance with said Section 638. A referee with the
qualifications required herein for arbitrators shall be selected pursuant to the
AAA's selection procedures. Judgment upon the decision rendered by a referee
shall be entered in the court in which such proceeding was commenced in
accordance with California Code of Civil Procedure Sections 644 and 645.

     (f)  Miscellaneous.  To the maximum extent practicable, the AAA, the
          -------------                                                  
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the Dispute with the
AAA.  No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulation, or to the extent necessary to exercise any judicial review rights
set forth herein.  If more than one agreement for arbitration by or between the
parties potentially applies to a Dispute, the arbitration provision most
directly related to the Loan Documents or the subject matter of the Dispute
shall control.  This arbitration provision shall survive termination, amendment
or expiration of any of the Loan Documents or any relationship between the
parties.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the day and year first written above.

                              SECURITY AGREEMENT


     1.   GRANT OF SECURITY INTEREST.  For valuable consideration, the
undersigned TIER TECHNOLOGIES, INC. ("Debtor"), hereby grants and transfers to
WELLS FARGO BANK, NATIONAL ASSOCIATION ("Bank") a security interest in all of
the property of Debtor described as follows (collectively, the "Collateral"):

     (a)  all Debtor's accounts, deposit accounts, chattel paper, instruments,
documents and general intangibles (collectively, "Rights to Payment"), now
existing or at any time hereafter, and prior to the termination hereof, arising
(whether they arise from the sale, lease or other disposition of inventory or
from performance of contracts for service, manufacture, construction, repair or
otherwise or from any other source whatsoever), including all securities,
guaranties, warranties, indemnity agreements, insurance policies and other
agreements pertaining to the same or the property described therein, and in all
goods returned by or repossessed from Debtor's customers;

     (b)  all Debtor's inventory, goods held for sale or lease or to be
furnished under contracts for service, goods so leased or furnished, raw
materials, component parts, work in process or materials used or consumed in
Debtor's business (collectively, "Inventory"), and all warehouse receipts, bills
of lading and other documents evidencing goods owned or acquired by Debtor, and
all goods covered thereby, now or at any time hereafter, and prior to the
termination hereof, owned or acquired by Debtor, wherever located, and all
products thereof, whether in the possession of Debtor, warehousemen, bailees or
any other person, or in process of delivery, and whether located at Debtor's
places of business or elsewhere;

     (c)  all Debtor's goods, tools, machinery, furnishings, furniture and other
equipment (collectively, "Equipment"), now or at any time hereafter, and prior
to the termination hereof, owned or acquired by Debtor, wherever located,
whether in the possession of Debtor or any other person and whether located on
Debtor's property or elsewhere, and all improvements, replacements, accessions
and additions thereto;

together with whatever is receivable or received when any of the Collateral or
the proceeds thereof are sold, leased, collected, exchanged or otherwise
disposed of, whether such disposition is voluntary or involuntary, including
without limitation, all Rights to Payment, including returned premiums, with
respect to any insurance relating to any of the foregoing, and all Rights to
Payment with respect to any cause of action affecting or relating to any of the
foregoing (collectively, "Proceeds").
<PAGE>
 
     2.   OBLIGATIONS SECURED.  The obligations secured hereby (the
"Obligations") are the payment and performance of:  (a) all present and future
Indebtedness of Debtor to Bank under or in connection with that certain Credit
Agreement between Debtor and Bank dated as of November 7, 1997, as amended from
time to time (collectively, with all substitutions therefor and replacements
thereof, the "Credit Agreement"); and (b) all obligations and Indebtedness of
Debtor and rights of Bank under this Agreement and the other Loan Documents (as
defined in the Credit Agreement).  The word "Indebtedness" is used herein in its
most comprehensive sense and includes any and all advances, debts, obligations
and liabilities of Debtor heretofore, now or hereafter made, incurred or
created, whether voluntary or involuntary and however arising, whether due or
not due, absolute or contingent, liquidated or unliquidated, determined or
undetermined, and whether Debtor may be liable individually or jointly with
others, or whether recovery upon such Indebtedness may be or hereafter becomes
unenforceable.

     3.   TERMINATION.  This Agreement will terminate upon the performance of
all of the Obligations, and the termination of all commitments of Bank to extend
credit to Debtor under the Credit Agreement or any other Loan Documents existing
at the time Bank receives written notice from Debtor of the termination of this
Agreement.

     4.   OBLIGATIONS OF BANK.  Bank has no obligation to make any loans
hereunder, such obligations, if any, being set forth in the Credit Agreement.
Any money received by Bank in respect of the Collateral may be deposited, at
Bank's option, into a non-interest bearing account over which Debtor shall have
no control, and the same shall, for all purposes, be deemed Collateral
hereunder.

     5.   REPRESENTATIONS AND WARRANTIES.  Debtor represents and warrants to
Bank that:  (a) Debtor is the owner and has possession or control of the
Collateral and Proceeds; (b) Debtor has the right to grant a security interest

Collateral are true and complete in all material respects; (e) no financing
statement covering any of the Collateral or Proceeds, and naming any secured
party other than Bank, is on file in any public office; (f) where Collateral

capacity to contract and are bound as they appear to be, all property subject to

and filed in compliance with law and to perfect the interest of Debtor in such
property, and all such Collateral and Proceeds comply with all applicable laws
concerning form, content and manner of preparation and execution, including

laws; and (g) where the Collateral consists of Equipment, Debtor is not in the
business of selling goods of the kind included within such Collateral, and
Debtor acknowledges that no sale of any such Collateral, including without
limitation, any such Collateral which Debtor may deem to be surplus, has been
consented to or acquiesced in by Bank, except as specifically set forth in

                                      -4-
<PAGE>
 
with an interest, are irrevocable until termination of this Agreement and may be
exercised from time to time by Bank's officers and employees, or any of them:

     (a)  whether or not an Event of Default has occurred: (i) to perform any
obligation of Debtor hereunder in Debtor's name or otherwise if Debtor has
failed to so perform after such notice as is reasonable under the then existing
circumstances; (ii) to give notice to account debtors or others of Bank's rights
in the Collateral and Proceeds; (iii) to release security; (iv) to prepare,

     (b)  after an Event of Default has occurred:  (i) to enforce Bank's rights
and make extension agreements with respect to the Collateral; (ii) to release
persons liable on Collateral or Proceeds and to give receipts and acquittances
and compromise disputes in connection therewith; (iii) to resort to security in
any order; (iv) to take cash, instruments for the payment of money and other

Obligations; (vii) to preserve or release the interest evidenced by chattel

of title incidental thereto; (viii) to exercise all rights, powers and remedies
which Debtor would have, but for this Agreement, with respect to all Collateral
and Proceeds subject hereto; and (ix) to do all acts and things and execute all
documents in the name of Debtor or otherwise, deemed by Bank as necessary,
proper and convenient in connection with the preservation, perfection or
enforcement of its rights hereunder.

     8.   PAYMENT OF PREMIUMS, TAXES, CHARGES, LIENS AND ASSESSMENTS.  Debtor
agrees to pay, prior to delinquency, all insurance premiums, taxes, charges,
liens and assessments against

                                      -5-
<PAGE>
 
the Collateral and Proceeds, and upon the failure of Debtor to do so, Bank at
its option may pay any of them and shall be the sole judge of the legality or
validity thereof and the amount necessary to discharge the same. Any such
payments made by Bank shall be obligations of Debtor to Bank, due and payable
within ten (10) calendar days after receipt of each billing from Bank, together
with interest at a rate determined in accordance with the provisions of Section
15 hereof, and shall be secured by the Collateral and Proceeds, subject to all
terms and conditions of this Agreement.

     9.   EVENTS OF DEFAULT.  The occurrence of any defined Event of Default
under the Credit Agreement shall constitute an "Event of Default" under this
Agreement.

     10.  REMEDIES.  Upon the occurrence of any Event of Default, Bank shall
have the right to declare immediately due and payable all or any of the
Obligations and to terminate any commitments to make loans or otherwise extend
credit to Debtor.  Bank shall have all other rights, powers, privileges and
remedies granted to a secured party upon default under the California Uniform
Commercial Code or otherwise provided by law, including without limitation, the
right to contact all persons obligated to Debtor on any Collateral or Proceeds
and to instruct such persons to deliver all Collateral and/or Proceeds directly
to Bank.  All rights, powers, privileges and remedies of Bank shall be
cumulative.  No delay, failure or discontinuance of Bank in exercising any
right, power, privilege or remedy hereunder shall affect or operate as a waiver
of such right, power, privilege or remedy; nor shall any single or partial
exercise of any such right, power, privilege or remedy preclude, waive or
otherwise affect any other or further exercise thereof or the exercise of any
other right, power, privilege or remedy.  Any waiver, permit, consent or
approval of any kind by Bank of any default hereunder, or any such waiver of any
provisions or conditions hereof, must be in writing and shall be effective only
to the extent set forth in writing.  It is agreed that public or private sales,
for cash or on credit, to a wholesaler or retailer or investor, or user of
property of the types subject to this Agreement, or public auction, are all
commercially reasonable since differences in the sales prices generally realized
in the different kinds of sales are ordinarily offset by the differences in the
costs and credit risks of such sales.  While an Event of Default exists: (a)
Debtor will deliver to Bank from time to time, as requested by Bank, current
lists of all Collateral and Proceeds; (b) Debtor will not dispose of any of the
Collateral or Proceeds except on terms approved by Bank; (c) at Bank's request,
Debtor will assemble and deliver all Collateral and Proceeds, and books and
records pertaining thereto, to Bank at a reasonably convenient place designated
by Bank; and (d) Bank may, without notice to Debtor, enter onto Debtor's
premises and take possession of the Collateral.  With respect to any sale by
Bank of any Collateral

                                      -6-
<PAGE>
 
subject to this Agreement, Debtor hereby expressly grants to Bank the right to
sell such Collateral using any or all of Debtor's trademarks, trade names, trade
name rights and/or proprietary labels or marks.

     11.  DISPOSITION OF COLLATERAL AND PROCEEDS.  Upon the transfer of all or
any part of the Obligations, Bank may transfer all or any part of the Collateral
or Proceeds and shall be fully discharged thereafter from all liability and
responsibility with respect to any of the foregoing so transferred, and the
transferee shall be vested with all rights and powers of Bank hereunder with
respect to any of the foregoing so transferred; but with respect to any
Collateral or Proceeds not so transferred, Bank shall retain all rights, powers,
privileges and remedies herein given.  Any proceeds of any disposition of any of
the Collateral or Proceeds, or any part thereof, may be applied by Bank to the
payment of expenses incurred by Bank in connection with the foregoing, including
reasonable attorneys' fees, and the balance of such proceeds may be applied by
Bank toward the payment of the Obligations in such order of application as Bank
may from time to time elect.

     12.  STATUTE OF LIMITATIONS.  Until all Obligations shall have been paid in
full and all commitments by Bank to extend credit to Debtor have been
terminated, the power of sale and all other rights, powers, privileges and
remedies granted to Bank hereunder shall continue to exist and may be exercised
by Bank at any time and from time to time irrespective of the fact that the
Obligations or any part thereof may have become barred by any statute of
limitations, or that the personal liability of Debtor may have ceased, unless
such liability shall have ceased due to the payment in full of all Obligations.

     13.  MISCELLANEOUS.  (a) The obligations of Debtor are joint and several;
(b) Debtor hereby waives any right (i) to require Bank to make any presentment
or demand, or give any notice of nonpayment or nonperformance, protest, notice
of protest or notice of dishonor hereunder, (ii) to direct the application of
payments or security for any of the Obligations, or any indebtedness of
customers of Debtor, or (iii) to require proceedings against others or to
require exhaustion of security; and (c) Debtor hereby consents to extensions,
forbearances or alterations of the terms of the Obligations, the release or
substitution of security, and the release of any guarantors; provided however,
that in each instance, Bank believes in good faith that the action in question
is commercially reasonable in that it does not unreasonably increase the risk of
nonpayment of the Obligations.  Until all Obligations shall have been paid in
full, Debtor shall not have any right of subrogation or contribution, and Debtor
hereby waives any benefit of or right to participate in any of the Collateral or
Proceeds or any other security now or hereafter held by Bank.

                                      -7-
<PAGE>
 
     14.  NOTICES.  All notices, requests and demands required under this
Agreement must be in writing, addressed to Debtor or to Bank at its address

                            TIER TECHNOLOGIES, INC.
                            VOTING TRUST AGREEMENT
                                        
     THIS AGREEMENT ("Agreement") is entered into as of November 3, 1997,
between James L. Bildner and William G. Barton, as trustees (with any
successors, the "Trustees" or individually, a "Trustee"), and the persons who
have executed this Agreement as Beneficiaries hereof or who become registered
owners of voting trust certificates pursuant to the terms of this Agreement
(individually, a "Beneficiary" and collectively, the "Beneficiaries") for the
purpose of ensuring that, during the term of this Agreement, the shares of Class
A Common Stock of Tier Technologies, Inc., a California corporation (the
"Company"), represented under this Agreement will be voted in a unified and
consistent manner. In the event, and whenever, there shall be only one Trustee
serving under this Agreement, the term "Trustees" shall refer to such Trustee or
to all Trustees together, as appropriate in the context.

     In consideration of the mutual agreements below, the Beneficiaries hereby
create and the Trustee hereby accepts a trust on the terms stated below, and the
parties hereto agree as follows:

1.   EXCHANGE OF SHARES FOR VOTING TRUST CERTIFICATES

     1.1.  Simultaneously with the execution of this Agreement, the
Beneficiaries shall deliver to the Trustees duly endorsed for transfer, or
accompanied by duly executed instruments of transfer, all shares of the Class A
Common Stock of the Company which that Beneficiary now owns or becomes the owner
of in the future. Promptly upon receipt of such shares, the Trustees shall cause
such shares to be registered in the name of the Trustees, and shall file a
duplicate copy of this Agreement with the Secretary of the Company.

     1.2.  The Trustees shall hold the shares transferred to them in trust (the
"Trust"), subject to the terms of this Agreement.

     1.3.  The Trustees shall issue and deliver to each Beneficiary a voting
trust certificate, in the form of Exhibit A hereto ("Certificate"), in respect
of the shares deposited with and held by the Trustees for the benefit of each
Beneficiary under this Agreement.

     1.4.  Until such time as this Agreement shall terminate, all stock
certificates representing shares held by the Trustee pursuant to the Trust shall
bear the following legend:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
     TO THE TERMS OF A VOTING TRUST AGREEMENT. ANY TRANSFEREE OF
     THESE SECURITIES TAKES SUBJECT TO THE TERMS OF SUCH
     AGREEMENT, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF
     THE COMPANY.

     1.5.  The Trustees shall keep at the principal office of the Company a book
(the "Certificate Book") containing the names of all persons who are
Beneficiaries and showing their places of residence, the number of shares
represented by the Certificates held by them, and the time when they became the
owners thereof. The Certificate Book shall be open for inspection by any
shareholder of the Company or any Beneficiary, or the agent of either, upon the
same terms as the record of shareholders of the Company is open to inspection by
such persons.

                                       1
<PAGE>
 
     1.6.  The Certificate shall be transferable only as provided in the
Certificate and this Agreement, and upon payment of any transfer taxes and other
charges. The term "Transfer" shall include, without limitation, any transfer,
sale, assignment, or alienation, regardless of the manner, circumstances,
timing, or nature of such transfer, and whether intervivos or at death. All
Transfers shall be recorded in the Certificate Book and any proper transfer made
of any Certificate shall vest in the transferee all rights of the transferor and
shall subject the transferee to the same limitations as those imposed on the
transferor by the terms of the Certificate transferred and by this Agreement.
Upon Transfer of any Certificate, the Trustees shall deliver a Certificate or
Certificates to the transferee for the number of shares represented by the
Certificate transferred.

     1.7.  If a Certificate shall be lost, stolen, mutilated or destroyed, the
Trustees, in their discretion, may issue a duplicate of such Certificate upon
receipt of (i) evidence of such fact satisfactory to the Trustees, (ii) an
indemnity satisfactory to the Trustees (or the existing Certificate, if
mutilated), and (iii) payment by the holder of the Certificate of all fees and
expenses applicable thereto.

     1.8.  The Trustees shall not be required to recognize any Transfer of a
Certificate not made in accordance with the provisions of the Certificate and
this Agreement. A Certificate is transferable, subject to the provisions of the
Certificate and this Agreement.

           1.8.1.  In the event of any Transfer which, pursuant to the terms of
the Articles of Incorporation of the Company, does not cause a conversion of
Class A Common Stock to Class B Common Stock, the underlying shares of stock
shall remain a part of this Trust and shall continue to be Class A Common Stock
shares. The affected Certificate shall be amended to reflect the Transfer and,
in the event of a Transfer of less than all the shares of the transferor, a new
Certificate shall be issued and delivered to the transferor.

           1.8.2.  In the event of a Transfer which, pursuant to the terms of
the Articles of Incorporation of the Company, causes a conversion of Class A
Common Stock to Class B Common Stock, the Trust shall terminate as to the shares
transferred. Any underlying shares of Class A Common Stock (with 10 votes per
share) which are transferred pursuant to this Section 1.8.2 shall be converted
to an equal number of shares of Class B Common Stock (with 1 vote per share),
consistent with the Company's Articles of Incorporation. Immediately after a
Transfer within the description of this Section 1.8.2, the subject Certificate
shall be surrendered to the Trustees (who shall return an amended Certificate to
the transferor in the event of a Transfer of less than all of the transferor's
shares), the affected shares shall be released from the Trust, and, after the
records of the Company have been properly adjusted to reflect the conversion,
the Trustees shall arrange for the delivery of a Class B Common Stock share
certificate to the transferee.

     1.9.  The Trustees may treat the registered holder of each Certificate (or
when presented duly endorsed by the registered holder with the signature of the
registered holder guaranteed in blank or to a transferee for Transfer, the
bearer or transferee thereof) as the absolute owner and holder thereof and of
all the rights and interests represented thereby for all purposes whatsoever,
and the Trustees shall not be bound or affected by any notice to the contrary.

2.   RECORD DATES

     2.1.  The Trustees may fix, in advance, a record date for the determination
of the Beneficiaries entitled to notice of any meeting of Beneficiaries or to
vote or to receive payment of any dividend or other distribution, or any
allotment of rights, or to exercise rights in respect of any other lawful
action. The record date so fixed shall be not more than 60 nor less than 10 days
prior to the date of the meeting nor more than 60 days prior to any other
action. If the purpose of the record date is a distribution pursuant to Section
4 of this Agreement, the record date shall be fixed so that each Beneficiary
shall receive all amounts to which such Beneficiary is entitled under Section 4.
When a record date is so fixed, only Beneficiaries of record on that date are
entitled to notice of and to vote at the meeting or to receive the dividend,
distribution or allotment of rights, or to exercise the rights, as the case may
be, notwithstanding any transfer of Certificates after the record date. A
determination of Beneficiaries of record entitled to notice of or to vote at a
meeting of Beneficiaries shall apply to any adjournment of the meeting unless
the Trustees fix a new record date for the adjourned meeting. The Trustees shall
fix a new record date if the meeting is adjourned for more than 45 days.

     2.2.  If no record date is fixed by the Trustees, the record date for
determining Beneficiaries entitled to notice of or to vote at a meeting of
Beneficiaries shall be at the close of business on the business day next
preceding the day on which notice is given or, if notice is waived, at the close
of business on the business day next preceding the day on which the meeting is
held. The record date for determining Beneficiaries for any purpose other than
set forth in this Section shall be at the close of business on the day on which
the Trustees adopt the resolution relating thereto, or the 60th day prior to the
date of such other action, whichever is later.

3.   TRUSTEE'S RIGHTS AS SHAREHOLDER OF COMPANY

     3.1.  Voting of Shares. During the existence of this Trust, the Trustees 
           ----------------      
shall have the exclusive right to vote all shares transferred to them in person
or by proxy at all shareholder meetings and in all proceedings in which the vote
or consent of shareholders may be required or authorized, and shall have all the
rights, privileges, and powers of shareholders except as otherwise provided in
this Agreement.

           3.1.1.  The right of the Trustees to vote, assent or consent shall
include, without limitation, the right to vote at any election of directors and
in favor of or in opposition to any dissolution or proposed dissolution,
liquidation or reorganization of the Company, or a sale of all or substantially
all of its assets, or the issuance or creation of additional classes of its
securities, or any action of any character whatsoever which may be presented at
any meeting or require the consent of shareholders of the Company.

           3.1.2.  Whenever there shall be more than one person serving as
Trustee hereunder, the Trustees shall exercise any power or take any action
under this Agreement with the assent of a majority of the Trustees. That assent
may be expressed at a meeting of the Trustees or without a meeting by vote or
resolution or by an instrument or separate instruments in writing signed by a
majority of the Trustees. As to any particular matter, should the Trustees fail
to come to any agreement as to what position or action to take (a "Deadlock"),
all shares in the Trust shall nonetheless be voted uniformly and the provisions
of Section 5.9 of this Agreement shall apply.

                                       3
<PAGE>
 
     3.2.  No Authority to Transfer Shares. The Trustees shall have no
           -------------------------------                            
authority to sell, pledge, hypothecate or otherwise dispose of the shares
deposited pursuant to the terms of this Agreement, except as specifically
provided in Section 3.3 of this Agreement.

     3.3.  Consolidation or Transfer of Shares. In the event that the Company
           -----------------------------------                               
shall merge into or consolidate with another corporation or entity, or in the
event that all or substantially all of the assets or shares of the Company are
transferred to another corporation or entity the shares or equity interests of
which are issued to shareholders of the Company in connection with that
transfer, then the term "Company" shall be construed to include the successor
corporation or entity and the Trustees shall receive and hold under this
Agreement any shares or other equity interests of the successor corporation or
entity received by the Trustees on account of their ownership, as trustees, of
shares held by them hereunder prior to the merger, consolidation or transfer.
Certificates issued and outstanding under this Agreement at the time of the
merger, consolidation or transfer may remain outstanding, but the Trustees may,
in their discretion, substitute therefor new Certificates in appropriate form.

4.   NOTICES AND DISTRIBUTIONS
     
     4.1.  The Trustees shall promptly forward copies of all notices, reports,
statements, and other communications received from the Company to the
Beneficiaries.

     4.2.  The Trustees shall promptly distribute all dividends and other
distributions received from the Corporation to the Beneficiaries.

     4.3.  If any dividend or stock split consists of additional shares having
voting rights, the Trustees shall hold these shares in trust subject to the
terms of this Agreement, and shall issue new voting trust certificates,
representing the additional shares to the Beneficiaries.

     4.4.  The Trustees may, if they deem it desirable to do so, arrange with
the Company for the direct payment by the Company of cash dividends or other
cash distributions to the Beneficiaries on the record date for any such dividend
or other distribution.

     4.5.  There shall be deducted and withheld from every distribution of every
kind under this Agreement any taxes, assessments and/or other amounts that may
be required by any present or future law or laws to be deducted or withheld, as
well as compensation of the Trustee as provided in Section 5.6 and expenses and
charges incurred pursuant to Section 5.5 to the extent that such compensation,
expenses and amounts remain unpaid or unreimbursed.

5.   THE TRUSTEE

     5.1.  Each Trustee by executing this Agreement, and each successor Trustee
upon being appointed as such, accepts the Trust created hereby and agrees to
carry out the terms and provisions of this Agreement. Each Trustee, in the
absence of his resignation, death or incapacity to act, shall serve for the
entire term of this Trust.

     5.2.  In voting shares or in doing any act in respect of the control or
management of the Company or its affairs, as the holders of shares deposited
under this Agreement, the Trustees shall exercise their best judgment, but the
Trustees assume no responsibility in respect of any vote made or act taken by
them or taken by the Company in pursuance of their vote or action as such
holders.

                                       4
<PAGE>
 
     5.3.  Should any question arise upon which the Trustees shall desire the
opinion of the Beneficiaries, a meeting for that purpose may be called by the
Trustees. Written notice of each such meeting shall be given not less than 10
nor more than 60 days before the date of the meeting to each Beneficiary
entitled to vote at it. The notice shall state the place, date and hour of the
meeting and the general nature of the business to be transacted, and no other
business may be transacted. Notice of such meetings shall be given either
personally or by mail, or by other means of written communication, addressed to
each Beneficiary at such Beneficiary's address appearing on the Trustees'
records or given by the Beneficiary to the Trustees for the purpose of notice;
or, if no such address appears or is given, at the place where the principal
executive office of the Company is located or by publication at least once in a
newspaper of general circulation in the county in which the principal executive
office of the Company is located. The notice shall be deemed to have been given
at the time when delivered personally or deposited in the mail or sent by such
other means of written communication. At any such meeting called by the
Trustees, the holders of a majority or more in interest of such Certificates may
determine the manner in which they desire the Trustees to act on the matter
submitted by the Trustees to the Beneficiaries for their determination (but
shall have no right to determine any matters not so submitted to them), and the
Trustees shall be bound to act in the manner so determined; provided, however,
that the Trustees shall not be required to take any action as a result of such a
meeting unless and until the Trustees have been fully and satisfactorily
indemnified against all loss, damage, claim or injury to which the Trustees
might be subjected, either by reason of their action or by reason of their
position as a trustee under this Agreement.

     5.4.  The transactions of any meeting of Beneficiaries, however called and
noticed by the Trustees, and wherever held, are as valid as though had at a
meeting duly held after regular call and notice by the Trustees, if holders of
the requisite amount and interest of Certificates shall have determined the
manner in which they desire the Trustees to act, and if, either before or after
the meeting, each of the persons entitled to vote, not present in person or by
proxy, signs a written waiver of notice, or a consent to the holding of the
meeting or an approval of the minutes thereof. Any action of the Beneficiaries
with respect (but only with respect) to any matter submitted to them by the
Trustees for determination may be taken without a meeting and without prior
notice if a consent in writing, setting forth the actions so taken, shall be
signed by the holders of outstanding Certificates having not less than the
minimum number of votes that would be necessary to authorize or take that action
at a meeting at which all Beneficiaries entitled to vote thereon were present
and voted. In the event of action of Beneficiaries without a meeting, pursuant
to the preceding sentence, the Trustees shall notify in writing all
Beneficiaries who have not consented thereto in writing of the action of
Beneficiaries so taken.

     5.5.  The costs of establishing and maintaining the Trust contemplated
herein shall be borne by the original Trustees.

     5.6.  The Trustees shall not be compensated for their services as the
trustees hereunder.

     5.7.  The rights and duties of any Trustee shall terminate upon his death,
and no interest in any of the property owned or held by the Trust nor any of the
rights or duties of a Trustee may be transferred by will, devise, succession, or
in any other manner except as provided herein. The heirs, administrators and
executors of such Trustee shall, however, have the right and 

                                       5
<PAGE>
 
duty to convey any property held by the Trustee to the remaining or successor
Trustee(s), as the case may be.

     5.8.  Any Trustee may resign by giving notice of resignation to (i) the
remaining Trustee(s), if there is at the time of such resignation more than one
person serving as Trustee, or (ii) to the Beneficiaries. Upon the resignation of
any Trustee, the remaining or successor Trustee(s), as the case may be, may
settle any account or transaction with such resigning Trustee, and obtain or
deliver full release and discharge upon such resignation.

     5.9.  In the event of a Deadlock, the matter(s) responsible for the
Deadlock shall be referred to a person (a "Mediator") who shall be selected by
the Trustees and who shall resolve the Deadlock. In the event that the Trustees
are unable, within 10 days of the occurrence of a Deadlock, to agree upon the
selection of a Mediator, then each Trustee shall appoint a designee, and the two
designees shall together select a Mediator to resolve the Deadlock.

           5.9.1.  Any determination made by a Mediator shall be final.

           5.9.2.  The Trustees jointly and severally hereby agree to indemnify,
defend, and hold any selected Mediator harmless from and against any and all
claims, damages, actions, suits or other charges incurred by or assessed against
the Mediator in the performance of his duties hereunder, except to the extent
resulting from his own gross negligence, fraud, or willful misconduct.

     5.10. In the event of the death, resignation or incapacity to act of the
Trustee or any successor Trustee, and provided that there remains one or more
incumbent Trustees, such incumbent Trustee(s) shall serve as the successor
Trustees.

     5.11. In the event of the death, resignation or incapacity to act of a sole
Trustee, leaving no incumbent or identified successor Trustee, this Agreement
shall terminate.

     5.12. Each successor Trustee shall enjoy all the rights, powers, interests
and immunities of the original Trustee. Notwithstanding any change in the
Trustee, the certificates for shares standing in the name of the Trustee may be
endorsed and transferred by any successor Trustee or Trustees for the time being
with the same effect as if endorsed and transferred by the Trustee who has
ceased to act. The successor Trustee is authorized and empowered to cause any
further transfer of such shares to be made which may be necessary through the
occurrence of any change of persons acting as Trustee hereunder.

     5.13. Whenever there shall be more than one person serving as Trustee
hereunder, the title to any property held by the Trustees shall be held in the
nature of a joint tenancy and not a tenancy in common, and there shall be
survivorship rights among the Trustees upon the death of any of them, and the
title of any Trustee who may die, resign or become incapacitated to act shall,
upon such death, resignation or incapacity, similarly vest in the remaining
Trustee or Trustees.

     5.14. The Trust created by this Agreement is not intended to be, and shall
not be deemed to be, and shall not be treated, as a general partnership, limited
partnership, joint venture, limited liability company, corporation or joint
stock company or association. The relationship of the Beneficiaries to the
Trustees shall be solely that of beneficiaries of the trust created by this
Agreement, and their rights shall be limited to those conferred upon them by
this Agreement.

                                       6
<PAGE>
 
     5.15. The Trustees from time to time may be parties to this Agreement as
Beneficiaries. The Trustees and any corporation, trust, firm, association or
other entity of which the Trustees may be trustees, shareholders, directors,
officers, members, agents or employees may contract with or be or become
pecuniarily interested, directly or indirectly, in any matter or transaction to
which the Company or any subsidiary or controlled or affiliated corporation may
be a party or in which it may be concerned, as fully and freely as though the
Trustees were not Trustees under this Agreement. The Trustees may act as
directors and/or officers of the Company or of any such subsidiary or controlled
or affiliated corporation and may vote the shares held hereunder in favor of
their election as directors and as directors may vote in favor of their election
as officers.

     5.16. The Trustees are authorized and empowered to construe this Agreement,
and the Trustees' reasonable construction made in good faith shall be conclusive
and binding upon the Beneficiaries and upon all parties hereto.

     5.17. The Trustees may consult with legal counsel, which may be counsel to
the Company, and any action under this Agreement taken or suffered in good faith
by the Trustees in accordance with the opinion of counsel shall be conclusive
upon the parties hereto, and the Trustees shall be fully protected and be
subject to no liability in respect thereof.

     5.18. Each Trustee shall not be liable for any error of judgment or for any
act done or omitted, or for any mistake of fact or law or for anything which
such Trustee may do or refrain from doing in good faith, nor shall the Trustee
have any accountability hereunder, except each Trustee shall be responsible for
that Trustee's own gross negligence, fraud, or willful misconduct.

     5.19. No Trustee shall be liable in any event for acts or defaults of any
other Trustee or Trustees or for acts or defaults of any employee, agent, proxy
or attorney in fact of any other Trustee or Trustees. Each Trustee shall always
be protected and free from liability in acting upon any notice, request,
consent, certificate, declaration, fax, telegram, telex, guarantee, affidavit or
other paper or document or signature believed by the Trustee to be genuine and
to have been signed by the proper party or parties or by the party or parties
purporting to have signed the same.

6.   TERMINATION

     6.1.  This Agreement shall terminate ten (10) years after the date of this
Agreement or on any later date to which the term is extended, as provided below,
without notice by or to, or action on the part of, the Trustees or the
Beneficiaries; provided that this Agreement may be terminated on an earlier date
upon the agreement of the Trustees to terminate this Agreement or upon an event
described in this Agreement.

     6.2.  As soon as practicable after termination of this Agreement, the
Trustees (or their heirs, administrators, executors or other representatives)
shall redeliver share certificates representing the appropriate number of
shares, properly endorsed for transfer, to the Beneficiaries, and the
Beneficiaries will surrender to the Trustees their voting trust certificates
properly endorsed. If any such Beneficiary cannot be located or fails or refuses
to surrender Certificates in exchange for share certificates or other securities
as stated above, the Trustees may in their discretion deliver the share
certificates or other securities to the Company or to any bank or trust company
in California for the benefit of the person or persons entitled thereto. 

                                       7
<PAGE>
 
Upon any such delivery, the Trustees shall be fully acquitted and discharged
with respect to the shares or other securities.

     6.3.  The termination of this Agreement shall not affect the rights and
protections of the Trustee set forth in Section 5. Except as otherwise provided
in this Agreement, the trust created by this Agreement is hereby expressly
declared to be irrevocable.

7.   EXTENSION

     7.1.  The term of this Agreement, as prescribed in Section 6, may be
extended from the original termination date of this Agreement or from the
termination date as last extended in accordance with this Section 7, provided
that within two (2) years before the date as originally fixed or as last
extended, the Beneficiaries desiring such extensions, by written agreement, and
with the Trustees' written consent, extend the term of this Agreement for an
additional term not to exceed ten (10) years from the expiration date then in
effect.

     7.2.  In the event of extension, duplicate copies of this Agreement and of
the extension agreement shall be filed with the secretary of the Company and
shall be open for inspection on the same conditions as the Company's record of
shareholders.

     7.3.  No such extension agreement shall affect the rights or obligations of
persons not parties to the extension agreement.

                              BUY-SELL AGREEMENT


          THIS BUY-SELL AGREEMENT ("Agreement") is entered into as of
______________________ ___, 1997 between James L. Bildner ("Bildner") and
William G. Barton ("Barton").

                                   RECITALS
                                   --------

          The holders of Class A Common Stock in Tier Technologies, Inc. (the
"Company") have created a voting trust (the "Trust") pursuant to the Voting
Trust Agreement of even date herewith (the "Voting Trust Agreement"). Bildner
and Barton (individually, a "Shareholder" and collectively, the "Shareholders"),
who are both trustees and beneficiaries of the Trust, seek to articulate, in the
form of this Agreement, procedures for the transfer of their Certificates (as
defined in the Voting Trust Agreement) in respect of shares of the Company
should such transfer become necessary or desirable.

          NOW, THEREFORE, incorporating the foregoing Recitals and in
consideration of the mutual agreements and covenants contained herein, the
parties hereby agree as follows:

                                      1.

                                 APPLICABILITY
                                 -------------

          1.1  Applicability. The terms and procedures set forth in this
Agreement shall apply to the transfer of Certificates either during life
("intervivos"), as set forth in Section 3, or at death, as set forth in Section
4.

                                      2.

                                  ENFORCEMENT
                                  -----------

          2.1  Restriction on Transfer. To accomplish the purposes of this
Agreement and the Voting Trust Agreement, any transfer, sale, assignment,
hypothecation, encumbrance, or alienation, regardless of the manner,
circumstances, timing, or nature or such transfer, whether intervivos or at
death (collectively, "Transfer"), of any Certificate(s) is void and transfers no
right, title, or interest in or to those shares to the purported transferee,
buyer, assignee, pledgee, or encumbrance holder, except as specifically provided
herein.

          2.2  Legend on Certificates. Each Certificate shall have the following
statement conspicuously printed on its face and each party shall cooperate in
the process of printing such statements:

                                       1
<PAGE>
 
               "The transfer, sale, assignment, hypothecation, encumbrance, or
          alienation of this certificate is restricted by a Buy-Sell Agreement
          dated ________, which may be inspected at the offices of the Company
          during normal business hours. All of the terms and provisions of the
          Buy-Sell Agreement are incorporated by this reference and made a part
          of this certificate."

                                      3.

                              INTERVIVOS TRANSFER
                              -------------------

          3.1  Generally. The Articles of Incorporation of the Company provide
that certain Transfers shall cause Class A Common Stock to be converted to Class
B Common Stock (a "Conversion").

               3.1.1  No Conversion. A Transfer of a Certificate that would not
result in a Conversion shall be permitted, with the terms of the Transfer to be
determined by the transferor and the transferee, in their sole discretion.

               3.1.2  Conversion. An intervivos Transfer of a Certificate that
would result in Conversion shall be prohibited for 5 years from the date hereof.
After the expiration of 5 years from the date hereof, such a Transfer would be
permitted, subject to the right of first refusal discussed in Section 3.2
hereof.

               3.1.3  Remain Subject. Any transferred Certificate shall remain
subject to this Agreement.

          3.2  Right of First Refusal. Before either Shareholder makes an
intervivos Transfer of a Certificate which would result in Conversion, the other
shall have the opportunity to purchase the Certificate under the terms of this
Section 3.2. The party desiring to Transfer his Certificate (the "Transferring
Party") shall inform the other party (the "Non-Transferring Party") of his
intent to Transfer. The Non-Transferring Party shall have two (2) days to decide
whether to purchase the Certificate. If the Non-Transferring Party decides not
to purchase the Certificate, or fails to respond to the Transferring Party's
notice, then the Transferring Party may make an intervivos Transfer of his
Certificate subject to the terms of the Voting Trust Agreement. If the Non-
Transferring Party decides to purchase the Certificate, the terms of the
purchase shall be as provided in Sections 3.2.1 and 3.2.2.

               3.2.1  Price. The purchase price for the Transfer described in
Section 3.2, stated on a per share of Class A Common Stock basis, shall be equal
to the market value of a share of Class B Common Stock of the Company on the
date that the Transferring Party notifies the Non-Transferring Party of his
intent to Transfer (pursuant to Section 3.2 hereof). The market value of the
Class B share shall be equal to the average of opening and closing values on the
day of the aforementioned notice. No premium or discount shall be taken for
differences in voting power between the Class A and Class B shares.

                                       2
<PAGE>
 
               3.2.2  Payment. Payment for the Transfer described in Section 3.2
shall be made within thirty (30) days of such Transfer, either in cash or with a
number of Class B Common Stock shares equal to the number of Class A Common
Stock shares represented by the transferred Certificate.

                                      4.

                               TRANSFER AT DEATH
                               -----------------

          4.1  Obligation to Purchase. Upon the death of either Shareholder, the
other (the "Survivor") shall have a fully recourse obligation to purchase the
Certificate of the deceased (the "Deceased"), under the terms set forth in this
Section 4.

          4.2  Price. The purchase price for the Transfer described in Section
4.1, stated on a per share of Class A Common Stock basis, shall be equal to the
market value of a share of Class B Common Stock of the Company on the date of
the Deceased's death. The market value of the Class B share shall be equal to
the average of opening and closing values on the day of the aforementioned
notice. No premium or discount shall be taken for differences in voting power
between the Class A and Class B shares.

          4.3  Payment. Payment for the Transfer described in Section 4.1 shall
be made as follows: As much of the purchase price as possible shall be paid in
cash, using solely the proceeds of the insurance policy described in Section 4.4
below. The remainder shall be paid within one hundred twenty (120) days of
death. The remainder may be paid (i) in cash; or (ii) with one share of Class B
Common Stock for each Class A Common Stock share represented by the transferred
Certificate, or any proportion of (i) and (ii).

          4.4  Insurance. Each Shareholder shall obtain a 10-year level term
life insurance policy on the life of the other, in the amount of $5 million, for
the purpose of making the payment contemplated in Section 4.3 (individually, a
"Policy" and collectively, the "Policies"). Each Shareholder hereby consents to
the acquisition of such policies and agrees to cooperate in the acquisition and
administration of the policies. The details of the policies are set forth in
Exhibit A attached hereto.

          4.5  Implementation. The following procedures shall apply to this
Section 4.

               4.5.1  Beneficiary and Payment. Each Shareholder shall be the
named beneficiary and beneficial owner of the Policy on the life of the other
Shareholder, and shall make premium payments on such Policy to the appropriate
insurance company.


               4.5.2  Transfers. The Shareholders agree that as long as this
Agreement is in effect, they will maintain the Policies and will not exercise
any of the rights, privileges, and benefits accruing under any policy they own
subject to this Agreement, nor will they Transfer any such policy.

                                       3
<PAGE>
 
               4.5.3  Delinquent Payment. The beneficial owner of each Policy
shall file with each insurance company insuring the life of a Shareholder under
this Agreement a request that copies of all delinquent payment notices be sent
to the insured Shareholder. If any premium is not paid in full on or before 10
days before it is due, the insured may pay the premium on behalf of the other
Shareholder. Payment by the insured shall be considered a loan to the other
Shareholder to be repaid on demand of the insured, with interest from the date
of payment at an annual rate equal to the maximum rate established by applicable
law as of such date.

               4.5.4  Proceeds. On the death of either Shareholder, the Survivor
shall collect the proceeds of the Policy on the life of the Deceased and pay
those proceeds over to the authorized legal representative of the Deceased for
the purpose of the payment contemplated in Section 4.3. Any proceeds in excess
of the purchase price provided in Section 4.2 shall be paid to the estate of the
Deceased.

               4.5.5  Release of Certificate. Once the full payment contemplated
by Section 4.3 has been made, the authorized legal representative of the
Deceased shall transfer the Certificate of the Deceased to the Survivor.

          4.6  Death of Both Parties. Upon the death of the second to die of
Bildner and Barton, the Trust terminates and so shall any obligations under this
Agreement terminate.

                                      5.

                               GENERAL PROVISIONS
