FOR IMMEDIATE RELEASE

                     NUMEREX REPORTS SECOND QUARTER RESULTS

REVENUE GROWTH EXCEEDS EXPECTATIONS RESULTING IN IMPROVED OPERATING PERFORMANCE

ATLANTA, AUGUST 5, 2004 - NUMEREX CORP. (NASDAQ: NMRX), today announced net
losses of $689 thousand for the second quarter of 2004 and $1.5 million
year-to-date. These results compare to net losses of $854 thousand and $2.0
million for the comparable periods of 2003. Fully diluted losses per share were
$(.06) for the quarter and $(.14) year-to-date. This compares to fully diluted
losses per share of $(.08) and $(.18) for the comparable periods of 2003. Net
sales were $5.8 million for the quarter and $10.5 million year-to-date, compared
to $4.7 million and $9.4 million for the comparable periods of 2003. Please see
attached financial statements for more details.

"Wireless data products and services grew steadily during the second quarter,"
stated Stratton Nicolaides, chairman and CEO of Numerex. "Our overall
Cellemetry-based M2M revenues increased by over 25% compared to the second
quarter of 2003 reflecting a positive trend in wireless network market activity
and a robust opportunity pipeline. Recurring Cellemetry-based M2M service
revenues generated during the quarter grew 28% in a year over year comparison to
second quarter last year. We view these favorable market and growth trends as
strong indicators of the future health of the business. We have also taken steps
to improve the productivity and reduce the ramp-up costs associated with our new
product launches. Specifically, MobileGuardian, our mobile tracking and security
solution, announced a contract with Southwest Dealer Services last month to
market and sell MobileGuardian units to the new car dealer market. As a result,
we expect an immediate reduction in our direct selling costs and anticipate an
improvement in sales performance by the fourth quarter when Southwest's
personnel are fully trained.

VendView, our wireless vending service, continues its successful launch in
Mexico and is on course for its US debut later this year. Unit sales to existing
customers have exceeded the 1000 unit mark, with several additional trials
underway in Mexico and the Caribbean. We expect to secure additional VendView
customers during the third quarter and balance of the year.

Our digital multimedia business experienced a strong quarter. Specifically, the
results for the quarter include the positive impact of an IBM order for video
conferencing equipment that will be used by a K-12 school district. The total
award was for over $1M with less than one-third shipped in the second quarter
leaving a substantial backlog that has recently been incremented by the order of
additional video conferencing equipment from another school district. Our
networking business also had a strong quarter with significant revenues
generated by the installation of equipment that provides E911 services for the
customers of cellular carriers.

As a result of an improvement in operating performance and working capital
efficiencies, specifically related to reduced inventory levels, which have
dropped six straight quarters in a row, Numerex was operating cash flow positive
for the quarter. Only fixed asset expenditures as well as capital lease
principal payments caused a slight decline in cash compared to the balance at
March 31, 2004. As we have noted in prior press releases, we entered into a
$4.5M term note earlier this year, which significantly strengthened our
financial position by both increasing cash and significantly reducing short-term
debt. The term note has delayed repayment terms and will require maximum cash
outlays for both principal and interest of less than $650 thousand during the
last six months of 2004. Actual cash outlays could be lower if the equity
payment feature of the note can be exercised.

Finally, with respect to third quarter of 2004, we estimate that total revenues
will range between $5.5M and $6.0M. As a result of this anticipated growth in
revenues as well as the reduction in overheads associated with new product ramp
costs, we expect a consequent reduction in operating losses in the third
quarter."
