EXHIBIT 10.20 FIRST AMENDMENT TO PURCHASE AGREEMENT THIS FIRST AMENDMENT TO PURCHASE AGREEMENT (this "Amendment") is made and entered into as of the 7th day of October, 1997, by and between BOETTCHER WESTERN PROPERTIES III LTD., a Colorado limited partnership ("Seller"), and M. PHILLIP CARDOZA ("Buyer"). Recitals This Amendment is made with reference to the following facts: A. Pursuant to a Purchase and Sale Agreement and Joint Escrow Instructions dated as of July 17, 1997 (the "Purchase Agreement"), Seller agreed to sell, and Buyer agreed to purchase, the retail center owned by Seller and commonly known as "Venetian Square Shopping Center" located in Stockton, California (the "Center"). B. As contemplated by the Purchase Agreement, Buyer had until August 15, 1997 (the "Financing Contingency Deadline"), to either satisfy certain financing contingencies enabling Buyer to proceed with the purchase of the Center, or terminate the Purchase Agreement. Buyer was unable to satisfy such financing contingencies prior to the expiration of the Financing Contingency Deadline, and consequently terminated the Purchase Agreement in accordance with the terms and conditions thereof. C. Seller and Buyer now desire to revive and reinstate the Purchase Agreement, to amend and modify the Purchase Agreement in certain respects, and to proceed with the purchase and sale of the Center contemplated by the Purchase Agreement, on the terms and subject to the conditions set forth in this Amendment.

The Purchase Agreement, as amended and modified by this Amendment, is hereby revived and reinstated and shall continue in full force and effect as if Buyer had never exercised its right to terminate the Purchase Agreement in accordance with the terms and conditions thereof. 3.

Buyer hereby acknowledges and agrees that all of the conditions to Buyer's obligation to purchase the Property contained in Article 6 of the Purchase Agreement, including, without limitation, Buyer's review of the documents described in Section 6.2 of the Purchase Agreement and the financing and leasing contingencies described in Section 6.3 of the Purchase Agreement, have been duly satisfied or waived by Buyer, and Buyer's right to terminate the Purchase Agreement pursuant to Section 6.4 of the Purchase Agreement is no longer of any force or effect whatsoever. 4.

In the event that either party elects to purchase the Environmental Liability Policy, which policy shall name both Seller and Buyer as insureds, Seller and Buyer shall each pay one-half of the cost of obtaining the Environmental Liability Policy, up to a maximum of $50,000 each; provided, that in the event that the Environmental Liability Policy is not commercially available for a premium of not more than $100,000, Buyer may elect to pay the full amount of the premium in excess of $50,000 in order to obtain the Environmental Liability Policy, such that Seller's contribution towards the cost of obtaining the Environmental Liability Policy shall in no event exceed the lesser of (a) one-half of the premium payable for such policy, or (b) $50,000. In the event of any termination of this Agreement pursuant to this Section 3.4, the Deposit shall be immediately released to Seller and thereafter, the parties shall be relieved from any further obligation or liability to the other pursuant to this Agreement except for those obligations which expressly survive the Closing or earlier termination of this Agreement pursuant to the provisions of Article 9 below; provided, that Buyer shall return all of Seller's Deliveries to Seller and shall provide Seller with copies of all reports, surveys, assessments, analyses or summaries thereof prepared by or on behalf of Buyer in connection with its investigations of the Property pursuant to Article 6 below." 3 The following is hereby added as new clause (iv) of Section 8.3 of the Purchase Agreement, and existing clause (iv) is hereby renumbered as clause (v): "(iv) the amount of Buyer's contribution against the premium payable for the Environmental Liability Policy (if applicable) in accordance with Section 3.4 above,..."
