Item 1.01 Entry into a Material Definitive Agreement

On August 8, 2011 LeCroy Corporation entered into a new $75,000,000 Credit Agreement (the “Credit Agreement”) with the lenders listed therein and RBS Citizens, N.A. as administrative agent for such lenders. The Credit Agreement will mature on August 8, 2016. The Credit Agreement replaces LeCroy’s Amended and Restated Agreement. RBS Citizens, N.A. is acting as sole lead arranger and sole book runner in connection with syndicating the credit facility.

The terms of the Credit Agreement provide LeCroy with a $75,000,000 revolving credit facility, which includes a $7,500,000 letter of credit subfacility. LeCroy has the right to increase the total revolving commitment to $90,000,000 at any time prior to the Revolving Maturity Date of the Credit Agreement upon meeting certain conditions. The performance by LeCroy of its obligations under the Credit Agreement is secured by all of the assets of LeCroy and its domestic subsidiaries, and is guaranteed by LeCroy’s domestic subsidiaries.

The proceeds of the borrowings under the Credit Agreement have and will be used to refinance existing debt, including the ability to retire the outstanding convertible notes in October 2011, fund short-term and long-term working capital, for issuance of Letters of Credit and general corporate purposes.

Borrowings under the Revolving Credit Agreement will bear interest at variable rates equal to, at LeCroy’s election, (a) a rate based on LIBOR or (b) Base Rate, plus a margin based on the Total Leverage Ratio. The Credit Agreement contains, among other things, conditions precedent, affirmative and negative covenants, representations and warranties and events of default customary for facilities of this size, type and purpose. Under certain conditions, the lending commitments under the Credit Agreement may be terminated by the lenders and amounts outstanding under the Credit Agreement may be accelerated.

The foregoing summary is qualified in its entirety by reference to the Credit Agreement, which is attached as Exhibit 10.1. The representations and warranties of the Company in the Credit Agreement were made only for purposes of that agreement and as of specific dates and were solely for the benefit of the lender party thereto. The Credit Agreement is a contractual document that establishes and governs the legal relations among the parties thereto and is not intended to be a source of factual, business, or operational information about the Company and its subsidiaries. The representations and warranties made by the Company in the Credit Agreement may be subject to the standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, investors and security holders should not rely on such representations and warranties as characterizations of the actual state of facts or circumstances.

The lenders under the Credit Agreement and its affiliates have provided and may continue to provide investment banking, commercial banking, financial services, or other services to the Company and its affiliates. They have received, and may in the future receive, customary fees and commissions for their services.

On August 8, 2011, LeCroy Corporation terminated its Amended and Restated Credit Agreement that was entered into on July 29, 2010.
