90017 (Attention: Mark Minsky -- Telephone No. (213) 484-0855 and Facsimile No.
(213) 484-0417) (the "Escrow Holder"), by depositing therein a fully-executed,
original of this Agreement.  Buyer and Seller shall execute any further standard

          -----------------

other than non-delinquent real estate taxes and assessments, shall be removed

vested in Buyer; provided, and if available, Buyer shall have the option of
obtaining additional ALTA title insurance coverage and any

                                       2

for the ALTA Policy and satisfies the Title Company's requirements in connection
therewith, if any.

manager to permit such property manager to accompany any such entry.  Buyer
hereby assumes all risk and expense relating to such entry, and hereby agrees to
indemnify, defend (with counsel reasonably acceptable to Seller), protect and
hold Seller, as well as Seller's principals, members, officers, directors,
partners (either general or limited), employees, agents and representatives
