                               AMENDMENT TO LEASE

     This agreement is entered into this 26th day of February, 1999, by and
between Biloxi Casino Corp. ("Biloxi") and Gary Gollott, Tommy Gollott and

     WHEREAS, on November 23, 1992, Biloxi and the Gollotts entered into an
agreement whereby Biloxi agreed to lease a thirty (30) foot by three hundred
(300) foot parcel of real property located south of U.S. Highway 90 in Biloxi,
Mississippi (the document shall hereinafter be referred to as the "Lease" and
the land subject to the Lease as the "Leasehold Estate"); and

     WHEREAS, on December 31, 1997, the Gollotts through an agreement with
Secretary of State Eric Clark in his capacity as Trustee of the Public Trust
Tidelands, confirmed the ownership of the Gollotts to a certain parcel of land
abutting the Leasehold Estate ("Confirmed Parcels'); and

     WHEREAS, a portion of the Confirmed Parcels were previously leased by
Biloxi from the State of Mississippi through Secretary of State Clark and not
from the Gollotts; and

     WHEREAS, the Confirmed Parcels are described on Exhibit A; and

     WHEREAS, the Parties now desire to amend the Lease by added the Confirmed
Parcels to the Leasehold Estate and by providing for an additional lease payment
from Biloxi to the Gollotts.

     NOW, THEREFORE, in consideration of the mutual promises and agreements set
forth herein, the sufficiency of which is acknowledged by the Gollotts and
Biloxi, the Parties agree as follows:

     1.   The above recitals are true and each is hereby incorporated as if
          fully set forth herein.

     2.   The Lease shall be amended only as follows:

          (i)  The Confirmed Parcel shall be added to the Leasehold Estate;

<PAGE>

          (ii)  Commencing in June 1998, Biloxi shall pay the Gollotts annually
                the sum of $3,000 as and for the lease of the Confirmed Parcel,
                with such sum to be adjusted annually by the CPI.

          (iii) The Gollotts, through the term of the Lease, agree to execute
                any and all documents relating to the Leasehold Estate that may
                be required by Biloxi or its affiliates in conjunction with any
                third party business transaction, including but not limited to
                estoppel certificates and landlord consents required for any
                loans with Bank of America, so long as the execution of any such
                document does not subordinate title to the Leasehold Estate or
                the right of the Gollotts to receive any lease payment
                therefore.

     3.   Other than as amended herein and except for provision 33 therein, all
          provisions of the Lease shall remain in full force and effect.

                                                  Biloxi Casino Corp.

RE: Convertible Promissory Note Restructure – RateXchange Option 
 
Dear Mr. Weiss: 
 
This letter will set forth our understanding and agreement regarding the restructure of the Convertible Promissory Note
between RateXchange Corporation (“RTX”) and Forsythe McArthur Associates, Inc. (“FMA”) dated, September 1, 2001: 
 

	 	1.	 	FMA currently holds a Convertible Promissory Note with principal sum of $5,949,042 and accruing interest at a rate equal to 9.0% per annum. Interest on the
Convertible Promissory Note is payable quarterly. 

 

	 	2.	 	RTX will pay interest on the Convertible Promissory Note for the fourth quarter of year 2002. RTX will not accrue or pay additional interest on the Convertible
Promissory Note for the period from January 1, 2003 through June 30, 2003, as described further below. 

 

	 	3.	 	RTX will purchase an option from FMA in exchange for 500,000 shares of RTX’s Common Stock and registration rights on those shares (the “Option”). The
Option will have a term beginning on the date first set forth above and ending on June 30, 2003. Upon RTX’s exercise of the Option, the Convertible Promissory Note will be cancelled and FMA will receive the following restructured consideration
in full and complete satisfaction of all obligations owed to it by RTX: 

 
a.  $500,000 in cash; 
b.  2,000,000 shares of RTX’s common stock, including demand registration rights; and 
c.  A new Promissory Note of principal sum equal to $1,000,000 bearing interest at 3.5% per annum payable
quarterly in cash, maturing on December 31, 2005. 
 

	 	4.	 	The 2,000,000 shares of RTX’s common stock will include a registration rights agreement wherein FMA will receive both piggyback and demand rights. RTX will file
the appropriate registration statement with the Securities and Exchange Commission on or before June 30, 2003. The registration statement will include the 500,000 shares granted to FMA for the Option and the interest shares earned by FMA under the
Restructure Agreement of October 4, 2001. The 2,000,000 shares included in the restructure consideration will be registered for resale if RTX exercises the Option. 

Letter to Mr. Weiss 
November 20, 2002 
Page 2 
 

	 	5.	 	Beginning on January 1, 2003 and ending on June 30, 2003, RTX will pay quarterly interest in cash to FMA based upon the terms of the new Promissory Note, i.e. 3.5%
per annum against the principal sum of $1,000,000. Should RTX exercise the Option, no interest will be due or payable under the Convertible Promissory Note subsequent to December 31, 2002 and the restructure terms set forth in Paragraph 3, will
apply and continue through maturity of the new Promissory Note. RTX may pre-pay its obligation under the new Promissory Note at anytime prior to maturity without penalty. Should RTX not exercise the Option; the amount of interest paid to FMA during
the Option Period will be credited against interest payments owed under the Convertible Promissory Note which will be paid on June 30, 2003. 

 

	 	6.	 	This Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements, restructures,
leases, understandings and negotiations, both written and oral, among any of the parties with respect to the subject matter of this restructure agreement.
