                 CATAPULT COMMUNICATIONS REPORTS RECORD REVENUES
                  AND INCOME FOR SECOND QUARTER OF FISCAL 2004

Mountain View, CA--April 15, 2004--Catapult Communications Corporation (Nasdaq:
CATT) today reported record quarterly revenues and net income for its second
fiscal quarter ended March 31, 2004. Total revenues for the quarter were $17.2
million, a 23 percent increase over revenues of $14.0 million reported in the
second quarter of fiscal 2003. Net income for the second fiscal quarter was a
record $4.5 million or $0.32 per diluted share. This compares to net income of
$1.7 million or $0.13 per diluted share in the second fiscal quarter of 2003.

Strong positive cash flow improved the Company's cash and short-term investment
position to $38.2 million, a $5.2 million increase over the first quarter of
fiscal year 2004.

"As a result of purchases by Japanese customers ahead of their March 31 fiscal
year end, our second quarter is typically the strongest of our fiscal year,"
said Dr. Richard A. Karp, Catapult's Chairman and CEO. "This year, for the
second quarter in a row, we saw increased demand in all our major regions: North
America, Europe and Japan. This increase was not fully reflected in revenue in
the second quarter because we gave shipping priority to Japanese fiscal year end
orders. As a result, 65 percent of our revenue in the second fiscal quarter was
generated in Japan, but we entered the third quarter with an uncharacteristic
backlog of North American and European orders."

BUSINESS OUTLOOK
"Our third fiscal quarter is historically sequentially lower due to slower sales
in Japan following their fiscal year end," Karp continued. "We currently expect
that our revenues in the third fiscal quarter will be $13.5 million, a 27
percent increase from the $10.6 million in the same quarter of fiscal 2003, and
that our diluted net income per share will be $0.15, a 50 percent improvement
from our net income of $0.10 per diluted share in the same quarter last year."
