Please be advised that beginning on Friday, May 11, 2001, a number of changes 
to the NYMEX End of Week post-close trading session rule that were recently

Specifically, beginning on Friday, May 11, 2001 and continuing for subsequent 
Friday post-close sessions (and post-close sessions the day before a mid-week 
Exchange holiday) the following changes will be in effect:

(1) Contract months eligible for trading in these sessions will be expanded 
from the first four to the first 12 consecutive listed contract months.

(2) The sessions will be 5 minutes in duration.

(3) The trading range for these sessions will be expanded by adding the 
following ticks above (below) the
daily high (low) for the applicable contract month (provided that this 
expanded trading range does not violate the maximum permissible price 
fluctuation limits then in effect):

Crude Oil  20 ticks
Heating Oil   50 ticks
Unleaded Gas   50 ticks
Natural Gas  50 ticks

AMENDMENTS TO NYMEX RULE 6.57(&POST-CLOSE TRADING SESSION8) AND
NYMEX RULE 6.57A (&END OF WEEK TRADING SESSION8)

(Asterisks indicate additions; brackets indicate deletions.)

Rule 6.57A.  END OF WEEK TRADING SESSION

On the last trading day of the calendar week, and, in any week when an 
Exchange holiday falls on a Tuesday, Wednesday or Thursday on the trading day 
preceding such midweek Exchange holiday, there shall be no post-close trading 
session provided on the trading floor pursuant to Rule 6.57.  Instead, on 
such dates, an end of week trading session (the &End of Week Session'') shall 
commence on the trading floor pursuant to this rule and subsequent to the 
close.  Except as otherwise provided by the President or the President,s 
designee for a particular trade date, such End of Week Session shall commence 
twenty (20) minutes after the close of trading in all futures contracts and 
shall continue for a period of [ten (10)]  * five
 (5) * minutes in all energy and metals futures contracts, subject to the 
following conditions:

(A) Trading during the End of Week Session shall be limited to the first 
[four] * twelve * listed delivery months;

(B) Trades occurring during the End of Week Session for a particular contract 
month of a futures contract shall be executed openly and competitively at a 
price within the daily trading range of the applicable contract month for 
that futures contract * and as further expanded above the daily high and 
below the daily low only for the contracts listed below provided however that 
no such expanded trading range may exceed the price fluctuation limits in 
effect for the applicable contract as of the end of the RTH session:

Contract    Additional Ticks

Crude Oil    20 ticks
Natural Gas    50 ticks
Unleaded Gasoline   50 ticks
Heating Oil    50 ticks *

(C) During the End of Week Session, Floor Members, Floor Brokers and their 
customers may participate in the same manner as trading occurring during the 
regular RTH session, except that any order submitted during the RTH session, 
including but not limited to resting orders such as stop orders, limit orders 
and good until cancelled (GTC) orders, will be deemed to have expired as of 
the end of RTH for purposes of this End of Week Session.  Accordingly, in the 
event that a market participant with such an expired order seeks to 
participate in the End of Week Session, a new order must be submitted.

(D) Prices for trades executed during the End of Week Session shall  be 
reported on public ticker services;

(E) Current market prices and trades executed during the End of Week Session 
shall not be considered in determining any settlement price; and

(F) Floor Members executing trades during the End of Week Session shall mark 
a line across their trading cards prior to the entry of an End of Week 
Session trade.
