Dear Sync Research Shareholder:

Our Annual Meeting of shareholders is scheduled to be held at 10:00 a.m.
local time, on Wednesday, August 30, 2000, at the Newport Beach Marriott
Suites, 500 Bayview Circle, Newport Beach, California. As most of you are
aware, Sync has entered into a merger agreement with Osicom Technologies,
Inc. (which we will refer to as "Parent"), a publicly held New Jersey
corporation (Nasdaq:FIBR), to acquire a wholly-owned subsidiary of Parent
doing business as Entrada Networks (which we will refer to as "Entrada").

In order to complete the merger, the holders of a majority of the shares of
Sync common stock and Series A Preferred Stock voting at the meeting must
vote in person or by proxy to authorize the issuance of shares of Sync common
stock under the merger agreement. As part of the merger, stockholders are
also being asked for approval to change Sync's name to "Entrada Networks,
Inc."

REMEMBER: FAILURE TO VOTE IS THE SAME AS A VOTE AGAINST THE PROPOSALS.

Only stockholders who held shares of Sync common stock or Series A Preferred
Stock at the close of business on July 18, 2000 will be entitled to vote at
the annual meeting.

YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
RECOMMENDS THAT YOU VOTE FOR THE MERGER PROPOSALS.

Quick and easy telephone and Internet voting instructions are enclosed.
Please take a brief moment to vote your Sync Research shares NOW.
