nine month periods ended March 31, 2005. A copy of the press release is being
furnished as Exhibit 99.1 to this Form 8-K and is incorporated herein by
reference in its entirety.

         The information furnished in this Form 8-K, including Exhibit 99.1,
shall not be deemed to be "filed" for purposes of Section 18 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to
the liabilities of that Section, nor shall it be deemed incorporated by
reference in any filing under the Securities Act of 1933, as amended, or the
Exchange Act.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

         This Current Report on Form 8-K contains forward-looking statements,
including those pertaining to LeCroy's belief that demand is continuing to
escalate for low- and mid-range oscilloscopes and protocol solutions, LeCroy's
optimism concerning its new high-performance digital oscilloscopes and the
Company's prospects in the high end oscilloscope market, LeCroy's expectations
relating to shipping, launching and performance of its new products, LeCroy's
expectation that Protocol Solutions will comprise 10-15 percent of its revenues
on an ongoing basis, LeCroy's belief that it is entering into the final phase of
its patent dispute litigation and that it is in the Company's best interest to
try its patent dispute, LeCroy's expectation that its patent dispute will be
brought to conclusion as a result of a November 2005 trial, LeCroy's expectation
that its legal expenses will increase in connection with the patent dispute,
LeCroy's cautious optimism regarding the Company's fourth quarter of fiscal
2005, LeCroy's expectation that the Company will see greater than 20 percent
growth in its fiscal fourth quarter with revenues of approximately $42 to $44
million, LeCroy's expectation that the Company will experience fourth quarter
seasonally higher expenses and legal expenses, and LeCroy's anticipation that
the Company will see pro forma operating income of approximately $4.5 to $5.5
million in the fourth quarter. These and other factors that could cause actual
results to differ materially, are discussed in more detail in the Company's
Annual Report on Form 10-K filed with the Securities and Exchange Commission on
