                  WHEREAS, the Borrower, the Agent and the Securities
Intermediary have discovered several errors in the Control Agreement and have
agreed that such errors should be corrected, effective as of the Original
Effective Date; and

                  WHEREAS, the parties desire to amend the Control Agreement in
certain other respects, as more particularly set forth herein.

                  NOW, THEREFORE, in consideration of the foregoing, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, and intending to be legally bound, the parties hereto agree
as follows

                  1.       Effective retroactively as of the Original Effective
Date, clause (b) of Section 2 of the Control Agreement is amended in its
entirety to read as follows:

                           "(b) All financial assets credited to a Collateral
                           Account shall be registered in the name of the
                           Securities Intermediary, endorsed to the Securities
                           Intermediary or in blank or credited to another
                           securities account maintained in the name of the
                           Securities Intermediary and in no case will any
                           financial asset credited to any Collateral Account be
                           registered in the name of XLReB, payable to the order
                           of XLReB or specially endorsed to XLReB except to the
                           extent the foregoing have been specially endorsed to
                           the Securities Intermediary or in blank."

                  2.       Effective as of the Original Effective Date, clause
(a) of Section 3 of the Control Agreement is amended by adding the following at
the end thereof:

                           "Notwithstanding the foregoing, the parties agree
                           that Control Collateral shall not include assets
                           pledged as collateral for futures contracts entered
                           into by XLReB,



                           which assets are custodied elsewhere but are
                           reflected in the Collateral Account for recordkeeping
                           purposes only (the "Subject Assets"). The Securities
                           Intermediary's records with respect to the Collateral
                           Account shall identify the Subject Assets as being
                           reflected in the account for recordkeeping purposes
                           only."

                  3.       Effective as of the date hereof, Section 4 of the
Control Agreement is amended by adding the following sentence after the first
sentence thereof:

                           "Without limiting the foregoing, if requested in
                           writing by the Agent and at all times following the
                           Securities Intermediary's receipt of a Notice of
                           Exclusive Control, the Securities Intermediary shall
                           promptly deliver to the Agent copies of each of the
                           "custom reports" which are prepared by the Securities
                           Intermediary for purposes of assisting the Borrower
                           in determining if the assets in the Collateral
                           Accounts constitute Borrowing Base Eligible Assets.

                  4.       Effective as of the date hereof, Section 5 of the
Control Agreement is amended by adding the following sentence at the end
thereof:

                           "For the avoidance of doubt, each of the parties
                           acknowledges and agrees that nothing in this
                           Agreement (i) shall be deemed to impose upon the
                           Securities Intermediary any obligation to determine
                           if any asset of the Borrower constitutes a Borrowing
                           Base Eligible Asset, or (ii) shall impose upon the
                           Securities Intermediary any liability for the failure
                           of any asset of the Borrower which has been
                           designated by the Borrower as a Borrowing Base
                           Eligible Asset in any report prepared by the Borrower
                           failing to, at any time, constitute a Borrowing Base
                           Eligible Asset."

                  5.       The Borrower represents and warrants to the Agent,
Citibank, CAFCO, CRC, CHARTA and CIESCO that immediately after giving effect to
this Agreement of Amendment (except to the extent that any such representations
or warranties expressly relate to an earlier date), (i) the representations and
warranties of the Borrower set forth in the Credit Agreement are true and
correct in all material respects, and (ii) no Default or Event of Default shall
be continuing.

                  6.       This Agreement of Amendment may be executed in any
number of counterparts, each of which when so executed shall be deemed to be an
original and all of which when taken together shall constitute one and the same
agreement.

                                       2


                  7.       THIS AGREEMENT OF AMENDMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                  8.       All references in any Program Document to the Control
Agreement on and after the date hereof shall be deemed to refer to the Control
Agreement as amended hereby, and the parties hereto agree that on and after the
date hereof, the Control Agreement, as amended hereby, is in full force and
effect.
