CIENA Announces Summary Judgement Granted in its Favor in Kimberlin Case

Linthicum, MD — 09/14/1998

A federal district court has dismissed federal securities law claims brought against Ciena Corporation (NASDAQ: CIEN) and certain of its individual directors by investor Kevin Kimberlin and related parties, finding "no violations" of federal securities laws in the Company's or directors' conduct. Kimberlin filed the lawsuit in November 1996 in the U.S. District Court for the Southern District of New York against the company and certain directors, alleging that Kimberlin and other parties controlled by him had been fraudulently denied the opportunity to purchase shares in Ciena in connection with a private offering in December 1995.

In a decision dated September 9, 1998, but received by the Company today following its morning conference call with financial analysts, U.S. District Court Judge Sonia Sotomayor granted Ciena's motion for summary judgement as to the Kimberlin plaintiffs' federal securities claims, finding "no violations of the federal securities laws in [Ciena's and the individually-named board members'] conduct." The Court also dismissed all related state law claims without prejudice, declining to exercise jurisdiction over these claims.

Patrick Nettles, Ciena's President and Chief Executive Officer said, "We are delighted that the court has agreed with our position that there was no basis for these claims, and we are pleased that we can put this distraction behind us and move forward with our business."
