ITEM 5.  OTHER EVENTS

         A.  PRESS RELEASE. On October 16, 2001, Teradyne, Inc. (the "Company")
issued a press release regarding its financial results for the Third
Quarter of 2001.  The Company's press release is filed as Exhibit 99.1 to this
Current Report on Form 8-K and incorporated herein by this reference.

         B. LITIGATION MATTERS. On September 5, 2001, a complaint was filed in
the Superior Court in San Diego County, California, naming as defendants the
Company and two of its executive officers. On October 9, 2001, defendants
removed the state court complaint to the U.S. District Court for the District of
Southern California. On October 12, 2001, plaintiffs filed an amended complaint
with the federal court. The amended complaint alleges, among other things, that
the sale of the Company's common stock in connection with the Company's
acquisition of each of Herco Technology Corp., a California company, and
Perception Laminates, Inc., a California company, violated certain California
securities statutes and common law, and that the Company breached certain
contractual obligations in the agreement relating to the acquisition. The
amended complaint seeks unspecified damages, including compensatory,
consequential and punitive damages, and recovery of reasonable attorneys' fees
and costs. The Company disputes the claims and believes they are without merit,
and intends to defend vigorously against the lawsuit.

         On October 16, 2001, a purported class action complaint was filed in

violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, by
making, during the period from July 14, 2000 and October 17, 2000, material
misrepresentations and omissions to the investing public regarding the Company's
business operations and future prospects. The complaint seeks unspecified
damages, including compensatory damages and recovery of reasonable attorneys'
fees and costs. The Company disputes the claims and believes they are without
merit, and intends to defend vigorously against the lawsuit.
