Catapult Communications to Be Acquired by Ixia

MOUNTAIN VIEW, CA, May 11 (MARKET WIRE) --
Catapult Communications Corporation (NASDAQ: CATT) announced today that
it has signed a definitive agreement with Ixia (NASDAQ: XXIA) under which
Ixia will acquire Catapult for $9.25 per share in cash. This represents a
39% premium to the average share price over the three months ended
Friday, May 8, 2009. The transaction is valued at approximately $105
million.

The acquisition will be conducted by means of a tender offer for all of
the outstanding shares of common stock of Catapult, followed by a
second-step merger. The board of directors of Catapult has unanimously
recommended that the stockholders of Catapult accept the offer, and
Richard A. Karp and Nancy Karp have entered into a support agreement to
tender their shares, which represent approximately 37% of shares
outstanding. The offer, which is expected to commence within the next ten
business days, will be subject to customary conditions, including the
tender of at least a majority of the shares outstanding on a fully
diluted basis and receipt of regulatory approvals. The tender offer is
expected to close by the end of June 2009 and the merger is expected to
close early in the third quarter.

"Based on a thorough evaluation of strategic alternatives, Catapult's
board of directors believes that this transaction provides both excellent
value and liquidity for our shareholders," said Richard A. Karp, Chairman
and CEO of Catapult Communications. "The combination of Catapult's
wireless expertise with Ixia's multiplay IP capabilities will offer the
market a single, powerful test solution that will benefit our customers
and employees."
