WHEREAS, on the date of this Addendum HCR and ALS have entered into an Agreement of Purchase and Sale (Construction Residences) (the "Construction Purchase Agreement") and an Agreement of Purchase and Sale (Operating Residences) (the "Operating Purchase Agreement" and, together with the Construction Purchase Agreement, the "Agreements"); WHEREAS, the parties wish to set forth in this Addendum certain agreements they have reached with respect to certain changes they shall make to the Agreements after the date hereof, notwithstanding anything to the contrary set forth in the Agreements. NOW, THEREFORE, intending to be legally bound, the parties agree as follows: 1. Terms designated with an initial capital letter and not otherwise defined herein shall have the meanings ascribed to such terms in the respective Agreements amended hereby. 2. Within thirty (30) days after the date hereof, the parties shall amend and/or restate the Agreements to provide as follows: A. Development Fees. In consideration of development services rendered by HCR and/or its subsidiaries with respect to the Construction Residences up to and including December 31, 1998, ALS shall pay to HCR, at the time of the first Residence Closing (whether for a Construction Residence or Operating Residence) development fees of $4,000,000. In addition, in consideration of development services to be rendered by HCR and/or its subsidiaries with respect to the Construction Residences after December 31, 1998 and until the completion thereof and rendered with respect to the Operating Residences, ALS shall pay to HCR aggregate development fees of $6,000,000, which shall be payable upon the Residence Closing of each Construction Residence (with the proportion of such $6,000,000 payable upon any such Residence Closing being equal to its proportionate share of the aggregate purchase price for all Construction Residences as indicated on Annex 1 hereto). B. Withdrawal Fee. In the event that any Operating Residence or Construction Residence is not sold by Seller to Purchaser and a Withdrawal Condition (as hereinafter defined) exists with respect thereto, Seller shall promptly pay to Purchaser a "Withdrawal Fee" with respect to such Residence in the amount set forth opposite such Residence's name on Annex 1 hereto. A "Withdrawal Condition" shall be deemed to exist if any of the following occur: (i) One or more conditions to Purchaser's obligation to close is not satisfied (and is not waived by Purchaser) and such Residence is withdrawn pursuant to Sections 14.C or 14.D of the applicable Agreement (unless Purchaser and Seller agree upon a substitute residence therefor in accordance with Section 14.D of the applicable Agreement); 2 (ii) Purchaser breaches its obligation to purchase, or Seller breaches its obligation to sell, such Residence under the applicable Agreement; or (iii) Such Residence is not sold by Purchaser to Seller for any reason (unless Purchase and Seller agree upon a substitute residence therefor in accordance with Section 14.D of the applicable Agreement). C. Liquidated Damages. The liquidated damages payable by Purchaser upon any breach of its obligation to purchase an Operating Residence or Construction Residence under the applicable Agreement shall be an amount equal to the product of $5,000,000 times the amount of the allocated purchase price for such Residence as set forth on Annex 1 hereof divided by $185,000,000, unless no Residence Closings occur under either Agreement, in which event liquidated damages shall be $9,000,000 for all of the Residences. D. Purchase Price. The purchase price for the Operating Residences and the Construction Residences pursuant to the Agreements shall be as set forth in Annex 2 hereto. 3. Pending the amendment and/or restatement of the Agreements in the manner contemplated by paragraph 2 hereof, this Addendum shall constitute an amendment of each of the Agreements effective as of the date hereof.
