CHARLTON, MA-- (June 5).

FiberCore (OTC-BB: FBCE), a leading manufacturer of optical fiber and preform
for the telecommunication and data communications market, today announced that
it has signed a multi-purpose agreement with Tyco Electronics Corporation, a
unit of Tyco International Ltd. (NYSE:TYC; LSE:TYI; DSX:TYC).

Under the agreement, Tyco Electronics will exercise its warrants and convert all
convertible notes and debt instruments of FiberCore held by Tyco Electronics to
common stock of FiberCore and terminate its shareholder voting agreement in
favor of a two year standstill agreement by Tyco Electronics. The agreement also
provides for possible future sales support arrangements and for exploring the
possibility for technology collaboration between FiberCore and Tyco Electronics.

Specifically, Tyco Electronics converted approximately $2.46 million into 3.4
million shares pursuant to the terms of its convertible note issued in April
1995. Pursuant to an early exercise of its warrants, issued in November 1996,
Tyco Electronics purchased approximately 2.8 million shares for $2 million. In
addition, Tyco Electronics converted the $4.13 million balance of its term loan
into approximately 1.03 million shares of FiberCore and released its liens on
all collateral.
