The class of securities to which this Statement relates
is the common stock, par value $.10 per share (the "Stock"), of

the Schedule 13D originally filed on December 28, 1998 on behalf
of the John R. Simplot Self-Declaration of Revocable Trust dated
December 21, 1989 (the "Trust"). The Trust is an inter vivos
revocable trust of which Mr. J.R. Simplot ("Mr. Simplot") is the
trustee and beneficiary. Mr. Simplot is a U.S. citizen. Mr.
Simplot is Chairman Emeritus of, and a consultant to, J.R.
Simplot Company, 999 Main Street, Boise, Idaho 83702.
The purpose of this Amendment is to report additional
purchases of Stock.

Item 5 with personal funds of the Trust and with funds provided
pursuant to customary margin arrangements between the Trust and
Merrill Lynch.

4,737,300 shares of Stock. As trustee of the Trust, Mr. Simplot
has the sole power to vote and dispose of such shares. Mr.
Simplot also shares voting and dispositive power with his son,
Don Simplot, for 60,000 shares of Stock held in a joint account
for the benefit of Don Simplot. Mr. Simplot disclaims any
beneficial interest in such shares.
Based upon information contained in the Quarterly

Exchange Commission for the quarter ended September 30, 1998 (the
