LeCroy Strengthens Position in Protocol Solutions with Acquisition of Catalyst Enterprises, Inc.

LeCroy Corporation (NASDAQ: LCRY) announced today that it has acquired Catalyst Enterprises, Inc., a manufacturer of data bus analysis and emulation tools for advanced serial data communications, for $30 million in cash and a $3.5 million note. The cash portion of the purchase price was funded from borrowings under the Company's revolving credit facility. On a non-GAAP basis, LeCroy expects the transaction to be accretive to earnings in the first full quarter of combined operations. The Company also announced preliminary first-quarter fiscal 2007 financial results.

LeCroy expects that acquiring Catalyst will enable it to:

• Broaden its line of Serial Data Protocol Analyzer Products
• Add an immediately accretive business, on a non-GAAP basis, to accelerate its growth
• Capitalize on growing enterprise customer demand in the network storage space
• Penetrate the market for entry-level PCI Express solutions
• Increase penetration of certain new customer and market segments
• Leverage its existing sales channel relationships and direct sales force for Catalyst's products
• Leverage its R&D capabilities to enhance Catalyst's technology

"With Catalyst, we are acquiring a highly complementary business that will be immediately accretive on a non-GAAP basis and will strengthen our position as leaders in protocol analysis," said President and Chief Executive Officer Tom Reslewic. "We intend to build on our successful entry into this market, which began with the acquisition of CATC (now LeCroy's Protocol Solutions Group) two years ago, by adding another engine to drive our growth. Catalyst will be integrated into our Protocol Solutions Group."

"Catalyst's roadmaps, product lines, branding strategies and distribution channels are complementary to LeCroy's," said Reslewic. "We have developed a strong presence in PCI Express and, most recently, PCI Express Gen2 with a successful line of high-end products for the computer space. Catalyst, meanwhile, has been successful penetrating the embedded PCI Express market with products designed for entry-level users. In the network storage market, Catalyst has achieved excellent penetration and developed strong customer relationships with a line of Serial ATA (SATA) and Serial Attached SCSI (SAS) products that focus on enterprise product developers. At the same time, LeCroy's storage solutions have performed well with device and disk drive customers. In addition, Catalyst's pipeline includes technology that is expected to significantly enhance LeCroy's offerings in the USB and Wireless USB markets. By combining the LeCroy and Catalyst roadmaps and product lines and leveraging LeCroy's channel relationships, we expect to significantly expand our footprint in both the computer and storage sides of the protocol analysis space while generating substantial savings in engineering and selling expense."

"In short, Catalyst has done a great job in the last two years of rapidly growing its business by targeting complementary segments with complementary products," said Reslewic. "Together, we will greatly extend the product line and the market reach of the combined entity."

Catalyst founder and CEO Nader Saleh said, "Joining an industry leader like LeCroy is a tremendous opportunity for Catalyst. LeCroy's Protocol Solutions business is a Bay Area corporate neighbor and a respected player in the serial data analysis market on which both our companies have focused since their inceptions. We expect significant short-term benefits for our customers through increased product breadth and feature sets and great long-term benefits due to the outstanding value generated by the combination of our companies. Together, the expectation is that LeCroy and Catalyst can roll out new products and grow faster within this market than either company could on its own." Saleh will remain with LeCroy as the Protocol Solution Group's Vice President of Technology.

Catalyst does not have audited financial statements and its financial statements were not prepared in accordance with U.S. GAAP. For the trailing 12 months ended September 30, 2006, on a cash basis, Catalyst's revenues grew 64.6% to $10.4 million from $6.3 million during the prior 12-month period. Catalyst's historical revenue may not be representative of what it would have been if it had been our subsidiary during that period. As of September 30, 2006, Catalyst had 28 employees.

"Catalyst has an outstanding team of employees and we look forward to welcoming them into the LeCroy family," said Reslewic. "Protocol analysis is an important growth opportunity for LeCroy. The ability to draw upon Catalyst's protocol solutions expertise will significantly enhance our ability to realize this potential. We are excited to be combining two leaders in complementary segments of this market, and we expect this combination to accelerate our growth and enhance our ability to achieve our strategic goals."
