by payment of the Exercise Price in the manner specified in the Warrant
Agreement (hereinafter defined). The number of Warrants evidenced by this
Warrant Certificate (and the number of Common Units which may be purchased upon
exercise thereof) set forth above, and the Exercise Prices per Common Unit set
forth above, are the number and Exercise Prices as of March 1, 2003 (the

such date, unless this Warrant Certificate is being issued after the Effective
Date pursuant to any provision for such issuance contained in the Warrant
Agreement, in which case such figures are based upon the Common Units of the
Company as constituted at the time of such issuance.

         As provided in the Warrant Agreement, the Exercise Price, the number of
Common Units which may be purchased upon the exercise of the Warrants evidenced
by this Warrant Certificate and the number of Warrants are, upon the happening
of certain events, subject to modification and adjustment.

         The "EXPIRATION DATE" is defined in the Warrant Agreement as five years

reference and made a part hereof and to which Warrant Agreement reference is
hereby made for a full description of the rights, limitations of rights,
obligations, duties and immunities hereunder of the Warrant Agent, the Company
and the Holders of the Warrant Certificates. Copies of the Warrant Agreement are
on file at the above-mentioned principal office of the Warrant Agent. To the
extent of any inconsistency between this Warrant Certificate and the Warrant
Agreement, the terms and conditions of the Warrant Agreement shall govern.

designated for such purpose at EquiServe Trust Company, N.A. c/o EOTT Energy
LLC, Transfer Operations, 150 Royal Street, Canton, MA 02021, (781) 575-2726 may

tenor and date evidencing Warrants entitling the Holder to purchase a like
aggregate number of Common Units as the Warrants evidenced by the Warrant
Certificate or Warrant Certificates surrendered shall have entitled such Holder
to purchase. If this Warrant Certificate shall be exercised in part, the Holder
shall be entitled to receive upon surrender hereof, another Warrant Certificate
or Warrant Certificates for the number of whole Warrants not exercised.

         At the option of the Company, no fractional Common Units will be issued
upon the exercise of any Warrant or Warrants evidenced hereby nor will Warrants
to purchase fractional Common Units be issued, but in lieu thereof a cash
payment will be made, as provided in the Warrant Agreement.

         No Holder of this Warrant Certificate shall be entitled to vote or
receive distributions or be deemed for any purpose the holder of Common Units or
of any other securities of the Company which may at any time be issuable on the
exercise hereof, nor shall anything contained in the Warrant Agreement or herein
be construed to confer upon the Holder hereof, as such, any of the rights of a
holder of the Common Units of the Company or any right to vote upon any matter
submitted to holders of the Common Units at any meeting thereof, or to give or
withhold consent to any Company action (whether upon any recapitalization,
issuance of Units, reclassification of Units, consolidation, merger, conveyance,
or otherwise) or, except as provided in the Warrant Agreement, to receive notice
of meetings, or to receive distributions or subscription rights or otherwise,
until the Warrant or Warrants evidenced by this Warrant Certificate shall have
been exercised as provided in the Warrant Agreement.

         This Warrant Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by the Warrant Agent.
