                 CATAPULT COMMUNICATIONS REPORTS FOURTH QUARTER
                       FISCAL YEAR 2003 FINANCIAL RESULTS

Mountain View, CA--October 30, 2003--Catapult Communications Corporation
(Nasdaq: CATT) today reported revenues of $10.2 million for its fourth fiscal
quarter ended September 30, 2003, an increase of 13% over the fourth quarter of
fiscal 2002. Net income for the quarter was $0.09 per diluted share, compared
with $0.02 per diluted share in the same quarter the previous year.

In absolute terms, quarterly net income was $1.23 million, after a $730,000
restructuring charge and the recognition of $1.5 million in additional tax
benefits. In the same quarter of the previous year, net income from continuing
operations was $242,000 after a $1.4 million acquisition-related charge.

Revenues for the fiscal year ended September 30, 2003 were $45.2 million, an
increase of 13% over fiscal 2002. Net income for the fiscal year ended September
30, 2003 was $4.4 million or $0.33 per diluted share. This compares to net
income of $9.2 million or $0.69 per diluted share for fiscal year 2002.

"Earnings were positively impacted since our previous published earnings
estimate due to the likely favorable completion of a tax audit by Japanese
taxing authorities," said Dr. Richard A. Karp, Catapult's Chairman and CEO.
"This positive change, which we learned of only in the past few days, resulted
in a favorable adjustment to our estimate of tax payable as at the end of the
fiscal year."

BUSINESS OUTLOOK

"Although my overall feeling is positive, I am not forecasting a return to more
normal revenue growth until we begin to see it occur", continued Karp.
"Therefore, I am projecting that revenues for the first quarter of fiscal 2004
are likely to be comparable to last fiscal year's first quarter at $10.4
million. On the bottom line, I expect that we will be able to achieve diluted
net income per share of $0.04 for the first quarter of fiscal 2004, an
improvement over the $0.01 per share over the first quarter of fiscal 2003."
