          Tier Signs Agreement to Acquire EPOS Corporation;
     Complementary Offerings Strengthen Presence in Core Markets

    RESTON, Va.--(BUSINESS WIRE)--June 1, 2004--Tier Technologies,
Inc. (Nasdaq:TIER), a leading provider of transaction processing and
packaged software and systems integration solutions for public-sector
clients, announced today that it has signed a definitive agreement to
acquire privately-held EPOS Corporation, a leading supplier of
interactive communications and transaction processing technologies.
    The aggregate purchase price of approximately $19.0 million is
comprised of $4.2 million in Tier Class B common stock, or
approximately 400,000 shares of Class B common stock, with the balance
representing cash and EPOS debt assumed by Tier. Tier projects that
the acquisition will add approximately $4.0 million to its revenue for
the fiscal year ending September 30, 2004, and expects the acquisition
to be neutral to slightly accretive to its fiscal year 2004 fully
diluted earnings per share on both a GAAP and Core basis. Tier
projects the acquisition will add approximately $15.0 million to its
fiscal year 2005 revenue and expects the acquisition to be accretive,
adding $0.03 to $0.04 to Tier's fiscal year 2005 fully diluted
earnings per share on both a GAAP and Core basis. Upon closing, it is
expected that the majority of EPOS' 80 employees will join Tier, and
that EPOS will operate as a business unit within Tier headed by
Michael A. Lawler, Chairman and President of EPOS. The acquisition is
expected to be completed this week.
    Founded in 1982, Auburn, Alabama based EPOS provides
state-of-the-art interactive communications and payment processing
solutions to its base of more than 800 customers. State and local
governments trust secure EPOS systems to store and process sensitive
citizen data. Colleges and universities process millions of
transactions through EPOS systems each semester for fee payment,
financial aid, class scheduling and grade reporting. Utilities rely
upon EPOS Interactive Voice Response (IVR) systems to provide vital
services such as account inquiry and payment and outage reporting.
State unemployment insurance agencies use EPOS IVR systems and call
centers to provide fast and efficient claims processing. Clients in
all markets use EPOS technology to streamline operations, increase
productivity and improve customer service.
    "We are delighted to welcome the strong management team and
experienced staff of EPOS to Tier," said James R. Weaver, Tier's
Chairman and Chief Executive Officer. "This acquisition is consistent
with our growth strategy. EPOS strengthens our position in core
markets such as state and local governments, and augments our
electronic transaction processing services. This enables Tier to offer
our customers an expanded service offering including new,
complementary products and services, and fits our targeted revenue,
profitability and valuation requirements."
    "EPOS fits well within Tier's business model of processing
transactions and implementing packaged software systems," Weaver said.
"Many of our existing child support operations have call center
aspects and we are seeing more child support RFPs that incorporate the
type of call center features that EPOS provides. Strong potential
synergies exist between EPOS' electronic transaction processing
premise-based and ASP solutions and our Official Payments Corp.
subsidiary, a leader in providing electronic payment services for the
IRS, 22 states, and more than 1,500 local governments. And we expect
EPOS' unemployment insurance operations to contribute enhanced
functionality to our strong unemployment insurance offering. EPOS
provides automated solutions for continuing claims processing and call
center solutions for initial claims processing for several large state
unemployment agencies."
    "This acquisition also establishes Tier as a strong player in
education institution transaction processing," Weaver continued. "EPOS
systems process transactions for approximately 450 of the more than
9,200 two and four year U.S. postsecondary educational institutions.
This attractive market is large and growing. For example, the U.S.
Department of Education reports that overall annual spending on
education in the United States, including postsecondary and K-12
education, was estimated to be $745 billion in the 2001-2002 school
year. Additionally, according to a 2002 U.S. Department of Education
report, enrollment in degree-granting postsecondary educational
institutions for the period 2000-2001 to 2011-2012 is projected to
increase from approximately 15.3 million to approximately 17.4 million
students, representing a 14% increase."
    "We are very excited to become part of the Tier team," said
Michael A. Lawler, Chairman and President of EPOS. "Joining Tier
enables us to jointly leverage our strong suite of complementary
offerings, for the ultimate benefit of our combined customer base."
