    DALLAS--(BUSINESS WIRE)--Oct. 24, 2007--Tyler Technologies, Inc.
(NYSE:TYL) today reported the following financial results for the

    --  Total revenues were $54.9 million, up 9.6 percent compared to
        $50.1 million in the same period last year. Software-related

        maintenance) grew in the aggregate 11.1 percent for the
        quarter.

    --  Operating income was $7.9 million, a 19.6 percent increase
        compared with operating income of $6.6 million in the same
        quarter of 2006.

        quarter ended September 30, 2006. Sequentially, gross margin
        for the third quarter improved from 37.6 percent in the second
        quarter of 2007.

    --  Selling, general and administrative expenses were $12.7

        including $198.2 million of software-related backlog and $27.6
        million of appraisal services backlog.

    --  Tyler is debt-free and ended the third quarter of 2007 with
        $48.7 million in cash and short-term investments. For the nine
        months ended September 30, 2007, the Company repurchased
        889,120 shares of its common stock at a cost of $11.1 million.

    Revenues for the nine months ended September 30, 2007 increased
10.6 percent to $159.4 million from $144.1 million in 2006. Operating
income for the first nine months of 2007 was $17.2 million, compared
to $15.5 million in the first nine months of 2006. Net income for the
nine months ended September 30, 2007 was $11.3 million, or $0.27 per
diluted share, compared to net income of $10.2 million, or $0.24 per
diluted share, for the comparable period of 2006.

    "Tyler continued to execute our business plan well and achieved
results for the third quarter that showed improvement in line with our
expectations," commented John S. Marr, Jr., Tyler's president and
chief executive officer. "We reached new quarterly highs in several
key measures, including total revenues, operating income, free cash
flow and backlog.

    "We are pleased that total revenues increased by nearly ten
percent to $55 million, even as we added to the base of recurring
revenues from customers who have selected our subscription-based
options, rather than purchasing the software under a traditional
perpetual license arrangement. These 'software as a service'
arrangements result in lower license revenues in the initial year as
compared to traditional perpetual license sales, but generate higher
overall revenues over the term of the contract. Although the number of
clients choosing our subscription-based options in the third quarter
represents a relatively small percentage of our new customers, the
average size of those contracts was larger than in prior quarters. In
fact, our two largest financial management system deals of the quarter
were application service provider contracts with the Fort Worth
Independent School District and the City of Richmond, California.

    "While this does not represent a fundamental change in our
business model, we provide our solutions to clients under a variety of
innovative options that address their specific needs. Government is
relatively deliberate in its pace of change, but over time, we expect
to generate significant subscription-based revenue. Our annualized
revenue run rate in the third quarter for these subscription services
is approximately $8.5 million, which is included in software services
revenue on our income statements, and we expect the new subscription
contracts signed in the third quarter will increase the annualized run
rate in future quarters to more than $10.8 million," continued Mr.
Marr.

    "This contract mix, coupled with contract terms on some existing
projects that dictate deferral of license revenue recognition until
certain milestones are achieved, contributed to a 21 percent decline
in license revenues from last year's third quarter. However, software
services revenues increased 26 percent, primarily driven by staffing
increases that enabled us to deliver more services associated with
implementations of our Odyssey courts and justice products, as well as
a higher level of subscription-based services revenues. In addition,
maintenance revenues increased 17 percent, reflecting our continued
growth in our customer base from new sales, coupled with extremely
high customer retention. Annual recurring revenues, including
subscription-based services as well as maintenance and support,
comprised approximately 45% of our total revenues in the third quarter
of 2007.

    "Free cash flow for the third quarter grew 34 percent over the
same period last year and for the first nine months of the year is
nearly double GAAP net income," added Mr. Marr. "For the trailing
twelve months ended September 30, 2007, Tyler posted $15.5 million in
earnings, or $0.37 per diluted share, on revenues of $210.5 million,
while generating $25.1 million of free cash flow (cash provided by
operating activities of $28.7 million minus capital expenditures of
$3.6 million). With total cash and investments of $48.7 million as of
September 30, we have the resources to invest in growing our business.

    "We continue to spend aggressively on product development, with
more than 420 developers working to maintain our competitive edge
through improving existing products and building new products. We have
also invested $9.0 million in cash in 'tuck-in' acquisitions this
year, including the purchase of EDP Enterprises, Inc. in September,
which significantly increased our presence in the public schools
market in Texas.

    "Our guidance for the full year 2007 remains generally consistent
with our communications last quarter. The markets we compete in
continue to be active, and in some cases robust. We believe the
Company is well-positioned to continue to execute our business model,
with attractive long-term revenue growth and margin expansion
opportunities," Mr. Marr concluded.

    Annual Guidance for 2007

    Total revenues for 2007 are currently expected to be in the range
of $217 million to $220 million. Tyler expects to have diluted
earnings per share of approximately $0.38 to $0.41 for the full year
2007. These estimates include assumed pretax expense for the year of
approximately $2.3 million, or $0.04 per share after taxes, related to
stock options and the Company's stock purchase plan. The Company
currently estimates that its effective income tax rate for 2007 will
be approximately 39 percent.

    Tyler expects that free cash flow for the year 2007 will be
between $25 million and $28 million (cash provided by operations of
$29 million to $31 million minus capital expenditures of between $3.5
million and $4.0 million).

    Non-GAAP Measures:

    This press release discloses the financial measures of EBITDA and
free cash flow. These financial measures are not prepared in
accordance with generally accepted accounting principles (GAAP) and
are therefore considered non-GAAP financial measures. The non-GAAP
measures should be considered in addition to, and not as a substitute
for, or superior to, operating income, cash flows, or other measures
of financial performance prepared in accordance with GAAP. The
non-GAAP measures used by Tyler Technologies may be different from
non-GAAP measures used by other companies. We believe the presentation
of these non-GAAP financial measures provides useful information to
users of our financial statements and is helpful to fully understand
our past financial performance and prospects for the future. We
believe these measures are widely used by investors, analysts, and
other users of our financial statements to analyze operating
performance and to compare our results to those of other companies,
and they provide a more complete understanding of our underlying
operational results and trends, as well as our marketplace performance
and our ability to generate cash. In addition, we internally monitor
and review these non-GAAP financial measures on a consolidated basis
as some of the primary indicators management uses to evaluate Company
performance and for planning and forecasting future periods.
Management believes that EBITDA and free cash flow provide meaningful
supplemental information to the investor to fully assess the financial
performance, trends and future prospects of Tyler's core operations.
