      TeleCommunication Systems, Inc. Reports Second Quarter 2004 Results



   Record $40 Million Revenue Yields Basic Earnings Per Share of $0.03 for

  Quarter, or $0.14 Per Share Adjusted for $0.11 Non-cash Charges Per Share


    ANNAPOLIS, Md., July 29 /PRNewswire-FirstCall/ -- TeleCommunication
Systems, Inc. (TCS) (Nasdaq: TSYS), a global leader in mission-critical
wireless data technology, today announced results for the quarter ended June
30, 2004.

    (Logo:  http://www.newscom.com/cgi-bin/prnh/20030618/TSYSLOGO )

    TCS reported total revenue for the quarter of $40.4 million vs. $20.1
million a year ago.  The increase includes $11.3 million from the Enterprise
segment acquired effective January 1, 2004 and $9.0 million, or a 45%
increase, from stronger results generated by both the Wireless Carrier and
Government segments in 2004.  Second quarter 2004 revenue was up $7.7 million
or 24% from the first quarter's $32.8 million on higher Wireless Carrier
software and Government revenue.

    Net income for the quarter ended June 30, 2004 was $0.9 million, or $0.03
per basic share and $0.02 per diluted share, versus a net loss of $11.4
million, or ($0.38) per share basic and diluted, in the second quarter of
2003.  Non-cash charges in Q2-04 were $3.6 million, including $0.6 million of
debt financing amortization related to the private placement completed during
the first quarter, vs. Q2-03's $10.0 million, which included a $7.0 million
accelerated amortization charge, and $3.3 million in the first quarter of
2004.

    The company's second quarter 2004 Adjusted Operating Income/loss, which is
a non-GAAP measure, was a record $0.14 per share (basic) vs. a loss of ($0.05)
per share in 2003, and a loss of $(0.01) in the first quarter of 2004.
Management believes that Adjusted Operating Income/(Loss), computed before
non-cash charges, is a useful measure in assessing operating performance and
generation of cash in addition to but not as a substitute for earnings
measured in accordance with generally accepted accounting principles, because
it is indicative of the availability of discretionary funds and the capacity
to service debt.

    As of June 30, 2004, we had unfulfilled orders, or backlog, of
approximately $83 million, of which we expect to realize approximately $34
million in the balance of this year and $52 million in the next twelve months.

    "This quarter's results represent profitability in three of the last four
quarters and positive second quarter profit for the first time as a public
company, reflecting solid execution of the company's business plan," commented
Maurice B. Tose, TCS' Chairman, President and CEO.  "As the second half of the
year is historically stronger for us than the first, management is optimistic
about full year results."

    "When we began the second quarter we were uncertain about the timing of
carrier customer purchases of messaging license capacity, and we are pleased
that such major procurements have been made sooner rather than later. Year to
date revenues are on track to meet our goals for the year, and our initiatives
in all three of our market segments should lead to higher serial quarterly
revenues," concluded Tose.


    OPERATIONAL HIGHLIGHTS

    Government Segment

    * We introduced the latest model in the SwiftLink suite of products, the
      SWIFTLINK(R) 1400.  This product is a highly portable reach-back
      communications terminal that provides encrypted access to classified or
      sensitive information from the field.  With support for both wire line
      and wireless infrastructure, the 1400 is the smallest in the SwiftLink
      product line with a footprint equivalent to a notebook computer.

    * Substantial progress was made during the quarter in rebuilding and
      expanding our communications engineering service business under multi-
      year contracts.

    Wireless Carrier Segment

    * Inquam affiliate, RadioMovel, selected TCS for its Xypoint Location
      Platform software and we signed an agreement to supply its first Code
      Division Multiple-Access (CDMA) Assisted Global Positioning Systems
      (AGPS) precise location solution throughout Europe.  Initially to be
      deployed in Portugal, TCS' solution will allow Inquam to offer a variety
      of Location-Based Services (LBS) to its growing subscriber base.

    * We are now deploying Phase II E9-1-1 for precise location information
      for Golden State Cellular in their local California market serving the
      central Sierras of California, including Yosemite, Mariposa, Sonora,
      Angels Camp, and Jackson.  Golden State Cellular was already using TCS'
      E9-1-1 Phase II Hosted Position Determining Entity (HPDE) service.

    * CommPartners has contracted with TCS to provide its E9-1-1 Voice Over
      Internet Protocol (VoIP) service, a set of comprehensive capabilities
      meant to address the broad range of challenges for emergency services
      which are posed by current VoIP technologies.

    Enterprise Segment

    * Progress was made during the quarter toward entering into new reseller
      arrangements for Blackberry mobile office device users in addition to
      the data network service that we currently provide our customers.

    * The Enterprise group's newest product, marketStream(TM), is now in
      trials with more than 100 companies globally.  The marketStream(TM)
      service provides global, real-time streaming access to equity security
      prices and volume, foreign exchange rates, futures, commodities and
      fixed income prices, as well as news and charts via any Java(TM)-based
      Blackberry handheld and is compatible with mobile phones and PDAs
      including the Sony Ericsson P800 and P900 and wireless-enabled PocketPC
      devices.

    * Corporate Express has now deployed more than one-third of its vehicles
      and distribution centers with TCS' 20/20 Delivery(TM) logistics
      management/point-of-delivery solution.

    FINANCIAL DETAILS

    Revenue and Gross Profit (revenue minus direct cost of revenue):


    Total revenue was $40.4 million in the second quarter of 2004, up 24% from
$32.8 million in the first quarter, and up 101% from $20.1 million in the
second quarter of 2003.  The addition of revenue from the acquired Enterprise
segment added $11.3 million to year-over-year results and both the Wireless
Carrier and Government segments contributed significantly higher year-over-
year results.


    The composition of second quarter revenue was as follows:

                                           Wireless
       ($ millions)          Government     Carrier    Enterprise      Total

    Service bureau and subscriber  $-         $9.6        $10.5        $20.1
    Software systems                -          8.2          0.8          9.1
    Network solutions            11.3            -            -         11.3
                   Total        $11.3        $17.8        $11.3        $40.4


    This compares to first quarter revenue of:

                                           Wireless
       ($ millions)          Government     Carrier    Enterprise      Total

    Service bureau and subscriber  $-         $9.1        $11.6        $20.7
    Software systems                -          3.5          1.0          4.5
    Network solutions             7.5            -            -          7.5
                   Total         $7.5        $12.6        $12.6        $32.8


    Total gross profit (revenue minus direct cost of revenue) was $17.5
million for the quarter, including $2.9 million contributed by the new
Enterprise segment, up $9.2 million from second quarter 2003's $8.3 million.
The company's overall gross margin was 43% in the most recent quarter, vs. 41%
a year ago, as high Wireless Carrier software license revenue in the quarter
just ended more than offset the effect of including the lower average margin
on Enterprise business. Compared to first quarter 2004 gross profit of $12.9
million, the $4.6 million improvement reflects Wireless Carrier software
license revenue and higher Government volume.


    Service bureau and subscriber revenue, substantially all of which is
    month-after-month charges to customers, was $20.1 million in the second
    quarter of 2004, down $0.6 million or 3% from Q1-04.  The expected $0.5
    million quarter-to-quarter increase in service bureau revenue was more
    than offset by the expected subscriber churn in low-margin Blackberry
    mobile office subscribers.  Our Blackberry business is transitioning to a
    market of multiple carrier alternatives, and in some cases, TCS now earns
    commissions on Blackberry placements in lieu of reseller margins.

    The gross profit from TCS service bureau and subscriber business was $7.4
    million, or 37% of revenue in the second quarter, consistent with $7.5
    million or 36% reported in Q1-04.

    Software systems revenue was $9.1 million in the second quarter of 2004,
    up 100% from $4.5 million in the first quarter, and up almost three-fold
    from second quarter 2003 revenue of $2.3 million.  Software systems
    revenue was comprised of over $8 million from the Wireless Carrier segment
    including a large purchase of messaging license capacity, and almost $1
    million from the recently acquired Enterprise segment.

    The gross profit from software systems was $5.9 million, or 65% of
    revenue, in the most recent quarter, up $3.7 million from $2.1 million, or
    47% of revenue, reported last quarter, and up $4.9 million from the $0.9
    million, or 41% of revenue in the second quarter of last year.  Revenue
    from the second quarter of this year was comprised of a higher proportion
    of higher-margin license revenue than was reported in prior comparative
    periods.

    Government Network Solutions revenue from systems integration and digital
    communications projects largely for government customers was $11.3 million
    in the second quarter, up from $7.5 million in the first quarter of 2004,
    and $9.5 million in the second quarter of 2003.

    The gross profit from Government Network Solutions was $4.2 million, or
    38% of revenue, vs. $3.3 million and 44% of revenue last quarter, and $3.0
    million or 32% of revenue in the second quarter of 2003.  The fluctuation
    in margins is attributable to changes in the Government Network Solutions
    sales mix.

    Operating Expenses:


    Second quarter 2004 cash operating expenses (R&D, sales and marketing, and
G&A) were $12.6 million, slightly down from $12.7 million in the prior
quarter, and up $3.1 million from the second quarter of 2003.  The increase
from prior year arises predominantly as a result of expenses associated with
the Enterprise segment.

    Research and development expenses for the quarter were $4.6 million. This
spending level compares to R&D investments of $5.0 million in the preceding
quarter and $4.7 million in the second quarter of 2003.

    Sales and marketing expenses totaled $3.3 million, up slightly from $3.2
million in the previous quarter, and from $2.2 million in the prior year.

    General and administrative expenses were $4.8 million in the second
quarter of 2004, up from $4.5 million last quarter, and from $2.7 million in
the second quarter of 2003, with the increase primarily associated with the
Enterprise segment and expenses associated with Sarbanes-Oxley 404 compliance.

    Net income for the second quarter 2004 was $0.9 million, or $0.03 per
basic share and $0.2 per diluted share, compared to a loss of $3.4 million, or
($0.11) per share, basic and diluted, in the first quarter of 2004 and a loss
of $11.4 million or ($0.38), basic and diluted, in the second quarter of 2003.
Basic per share figures were computed on the basis of 32.6 million, 31.9
million, and 29.6 million weighted average outstanding shares, respectively,
in Q2-04, Q1-04, and Q2-03. Diluted weighted average shares outstanding were
36.6 million during the quarter ended June 30, 2004.

    The company's cash and cash equivalents balance was approximately $16
million at June 30, 2004 versus $20 million at March 31, 2004. Our
aforementioned operating earnings before non-cash charges of $0.14 per share
equates to $4.5 million.  The net use of cash during the quarter was primarily
to fund the larger working capital balance associated with higher revenue, and
for capital expenditures associated with our E9-1-1 business.  Approximately
$7 million was available under the Company's bank line of credit at June 30.

    This press release discloses the Company's adjusted net income/(loss)
before non-cash charges (depreciation, amortization, and other non-cash
expenses), which may be considered a non-GAAP financial measure.  As used
herein, "GAAP" refers to generally accepted accounting principles in the
United States.  Generally, a non-GAAP financial measure is a numerical measure
of a company's performance, financial position, or cash flows that either
excludes or includes amounts that are not normally excluded or included in the
most directly comparable measure calculated and presented in accordance with
GAAP.  The Company believes that Adjusted operating income/loss is an
appropriate measure of evaluating its operating performance and liquidity
because the measure is indicative of the Company's availability of
discretionary funds and its capacity to service its debt, and thereby provides
additional useful information to investors regarding its financial condition
and results of operations.  This measure, however, should be considered in
addition to, and not as a substitute or superior to, operating income, cash
flows, or other measures of financial performance prepared in accordance with
GAAP.  The non-GAAP measure included in the Company's press release has been
reconciled to the nearest GAAP measure as is required under the rules of the
Securities and Exchange Commission regarding the use of non-GAAP financial
measures.

    This announcement contains forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of
the Securities and Exchange Act of 1934, as amended.  These statements are
based upon TCS' current expectations and assumptions that are subject to a
number of risks and uncertainties that would cause actual results to differ
materially from those anticipated.  The words, "believe," "expect," "intend,"
"anticipate," and variations of such words, and similar expressions identify
forward-looking statements, but their absence does not mean that the statement
is not forward-looking.  Statements in this announcement that are forward-
looking include, but are not limited to, Mr. Tose's comments that the Company
is optimistic about full year results, year-to-date revenues are on track to
meet goals for the year, and that its initiatives should lead to higher serial
quarterly revenues.

    Our backlog at any given time may be affected by a number of factors,
including contracts being renewed or new contracts being signed before
existing contracts are completed, and some of our backlog could be cancelled
for causes such as late delivery, poor performance and other factors.
Accordingly, a comparison of backlog from period to period is not necessarily
meaningful and may not be indicative of eventual actual revenue.

    The actual results realized by the Company could differ materially from
the statements made herein, depending in particular upon the risks and
uncertainties described in the Company's filings with the Securities and
Exchange Commission (SEC).  These include without limitation risks and
uncertainties relating to the Company's financial results and the ability of
the Company to (i) sustain profitability, (ii) continue to rely on its
customers and other third parties to provide additional products and services
that create a demand for its products and services, (iii) conduct its business
in foreign countries, (iv) adapt and integrate new technologies into its
products, (v) expand its sales and business offerings in the wireless data
industry, (vi) develop software without any errors or defects, (vii) have
sufficient capital resources to fund the company's operations, (viii) protect
its intellectual property rights, (ix) implement its sales and marketing
strategy, and (x) successfully integrate the assets and personnel of acquired
entities, such as the Enterprise net assets acquired from Aether Systems, Inc.
Existing and prospective investors are cautioned not to place undue reliance
on these forward-looking statements, which speak only as of the date hereof.
The Company undertakes no obligation to update or revise the information in
this press release, whether as a result of new information, future events or
circumstances, or otherwise.

    Management believes that Adjusted Operating Income/(Loss), excluding non-
cash charges, in conjunction with the complete Statement of Operations, is
helpful in assessing the operating performance of the Company. It is
calculated by adjusting GAAP net income/(loss) to exclude the effects of non-
cash compensation expense, depreciation and amortization, amortization of
software development costs, amortization of identifiable purchased intangible
assets, and non-cash interest expense.  A reconciliation to net income/(loss)
follows:
