                                  AMENDMENT TO
                         AGREEMENT TO PURCHASE AND SELL


     WHEREAS, JCC Fulton Development, L.L.C., a Louisiana limited liability
company ("Seller"), and WI Acquisition Corporation, a Delaware corporation
("Purchaser"), did enter into that certain Agreement to Purchase and Sell dated
February 14, 2000 (the "Agreement"), for the sale of Lot 3CP, Second Municipal
District of the City of New Orleans, Orleans Parish, Louisiana, on terms and
conditions more fully set forth therein;

     WHEREAS, Purchaser did assign to 3CP Associates, L.L.C., a Louisiana
limited liability company (now substituted as "Purchaser") all of its right,
title and interest in and to the Agreement by that certain Assignment and
Assumption of Agreement to Purchase and Sell effective as of April 17, 2000;

     WHEREAS, Seller and Purchaser have extended the expiration of the
Inspection Period (as defined in the Agreement) from time to time to July 20,
2000, and desire to further extend the Inspection Period as hereinafter set
forth; and

     WHEREAS, Seller and Purchaser also desire to amend this Agreement in
certain particulars as hereinafter set forth;

     NOW, THEREFORE, in consideration of the mutual covenants and warranties
hereinafter set forth, and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, Seller and Purchaser
hereby agree as follows:

     1) Capitalized terms utilized herein and not otherwise defined herein shall
have the meaning ascribed to them in the Agreement.

     2) Section 6.4 of the agreement, "Lender Consent," is hereby deleted in its
entirety as written, and amended to read as follows:

     "6.4 Lender Consent. (A) Seller shall take all reasonable efforts to obtain
     the Lender Consent on or before December 31, 2000 (the "Lender Consent
     Deadline"). Seller and Purchaser shall each have the option of extending
     the Lender Consent Deadline one or more times to a date not later than June
     30, 2001. If either party elects to extend the Lender Consent Deadline as
     described in the preceding sentence, such party shall give the other party
     written notice of such extension in accordance with Section 14.3 of the
     Agreement, prior to the expiration of the Lender Consent Deadline (as the
     same may be extended from time to time). If the Lender Consent Deadline is
     extended as provided in this Section 6.4, the definition of "Lender Consent
     Deadline" shall be automatically revised to mean the date specified in any
     such notice made in compliance with this Section 6.4(A).


(B) If Seller fails to obtain timely the Lender Consent, either Purchaser or
Seller may terminate this Agreement upon written notice to the other party, and
if either party so elects to terminate this Agreement, Purchaser shall be
entitled to a return of the Deposit and the Additional Deposit, if any, and, in
addition, Seller shall reimburse Purchaser for all of Purchaser's actual,
out-of-pocket expenses incurred in connection with the Transaction in the amount
set forth on Exhibit "A" attached hereto and made a part hereof. Seller's
obligation to reimburse Purchaser for such expenses shall be subject to
Sellers's audit and verification of

invoices for expenses incurred in connection with the Transaction as shown on
Exhibit "A" attached hereto.

         3) Section 8.1 of the Agreement, "Purchaser's Inspections," is hereby
deleted in its entirety as written, and amended to read as follows:

         "8.1 Purchaser's Inspections. Seller agrees that Purchaser shall have
         forty-five (45) days after (i) receipt of notice from Seller that the
         Lender Consent has been obtained or (ii) the Lender Consent Deadline,
         whichever is earlier, to conduct inspections of the Property
         ("Inspection Period"), including, without limitation, environmental
         audits, wetlands determinations, appraisals, zoning, economic and
         engineering feasibility studies, soil tests, and such other inspections
         as Purchaser deems necessary to satisfy itself with respect to Seller's
         title and the condition of the Property. Seller understands and agrees
         that Purchaser and its respective employees, agents, and
         representatives may find it appropriate to contact Governmental
         Authorities in connection with the result of Purchaser's Inspections to
         the Property. Purchaser's sole remedy for any defects in the Property
         discovered during the Inspection Period will be its termination rights
         established in Section 8.5."

         4) The "Effective Date" of this Amendment shall be the date on which
this Amendment is last executed by either Seller or Purchaser.

         5) Except as specifically amended hereby, all other terms and
provisions of the Agreement, as previously amended, remain in full force and
effect and are hereby ratified and confirmed in all respects.

         This Amendment may be executed in multiple identical counterparts. If
so executed, each such counterpart is to be deemed an original for all
purposes, and all such counterparts shall collectively constitute one agreement.
