                         CATAPULT COMMUNICATIONS REPORTS
                     THIRD FISCAL QUARTER FINANCIAL RESULTS

Mountain View, CA--July 24, 2003--Catapult Communications Corporation (Nasdaq:
CATT) today reported that revenues for its third fiscal quarter ended June 30,
2003 were $10.6 million, compared to $8.0 million in the same quarter the prior
year. Net income for the third fiscal quarter of 2003 was $1.4 million or $0.10
per diluted share. This compares to net income of $1.9 million and earnings of
$0.14 per diluted share for the third fiscal quarter of 2002.

"In the quarter just completed, although most of our earnings came from a
reversal of the tax provision, operating income remained positive and we
generated $2.4 million in cash and short-term investments," noted Dr. Richard A.
Karp, Catapult's Chairman and CEO.

BUSINESS OUTLOOK

"We continue to believe that our top line is stable and we are not losing
significant sales to competition," Karp continued, "but our experience in this
past quarter indicates that it is still too early to look for revenues to
recover. In these conditions, we could no longer afford to keep our expenses at
last quarter's level, and thus reduced our staff by 15% earlier this week. This
action will result in a one-time charge for termination costs of approximately
$750,000 or six cents per share in the current quarter and will produce an
ongoing reduction in costs of approximately $3.8 million per annum.

 "For the fourth fiscal quarter, we are projecting that revenues will remain
sequentially flat at $10.5 million. This would represent an increase of 17% over
the same quarter in the previous fiscal year. We are projecting that diluted
earnings per share for the fourth fiscal quarter on a GAAP basis will be zero
cents, given that the cost savings available in the remainder of the quarter
from the staff reduction are expected to be offset by the charge for termination
costs. We are projecting diluted earnings per share of six cents per share for
the fourth fiscal quarter on a pro forma basis excluding the charge for
termination costs," concluded Karp.
