obtained a release (the "Release") (and provided to Seller) from the current
holder of the beneficial interest (the "Holder") of a certain Covenant to Grant
Easement, dated March 19, 1985, and recorded as Recorder's Fee No. 85012768 in

right, title, interest and claim that the Holder may have in or with respect to
the Easement, provided, however, that the Closing Date shall not be later than
July 10, 1996.  The Closing shall be at the office of Title Insurer, in
Portland Oregon, at which time Seller shall deliver possession of the Property
to Purchaser, provided, however, that so long as Purchaser is not in default
hereunder, Purchaser shall have two (2) options to extend the Closing Date for
purposes of a 1031 Exchange (see Paragraph 18) to July 17, 1996 and August 16,
1996, respectively, by (a) giving written notice to Seller of the exercise of

the applicable option to extend no later than five (5) business days prior to
the then applicable Closing Date (as the same may have been extended) and (b)
depositing in each instance at least five (5) business days prior to the then
applicable Closing Date (as the same may have been extended) an amount equal to
Twenty-Five Thousand and No/100 Dollars with the Title Insurer, which sum(s)
shall be part of and included in the definition of "Earnest Money" and shall be
governed by the terms of the Escrow Agreement.  This transaction shall be
closed through an escrow with Title Insurer, in accordance with the general
provisions of the usual and customary form of deed and money escrow for similar
transactions in Oregon, provided, however, that in any instance, the sale
proceeds shall not be disbursed from such escrow unless and until the Title
Insurer shall be unconditionally committed to issuing the Title Policy.  All
closing and escrow fees shall be divided equally between the parties hereto."

7.   (a) Paragraph 2 of the Escrow Agreement is hereby amended and restated to
read in its entirety as follows:

     "On or before July 1, 1996 Purchaser may deliver to Escrow Agent a notice
in the form of Schedule 1 attached hereto that Purchaser has elected to
terminate the Agreement pursuant to the terms of that certain Second Amendment
to Agreement of Sale and Escrow Agreement dated as of June 13, 1996 (the "Due
Diligence Termination Notice").  In the event that Purchaser shall deliver to
Escrow Agent the Due Diligence Termination Notice on or before July 1, 1996,
Escrow Agent shall promptly deliver to Purchaser the Earnest Money, together
with all interest earned thereon, and thereafter this Escrow Agreement shall be
null and void." 

     (b)  Paragraph 3 of the Escrow Agreement is hereby amended and restated to
read in its entirety as follows:

     "The Closing Date shall be the date established pursuant to Paragraph 8 of
the Agreement.  Unless terminated pursuant to Paragraph 2 above, on the Closing
Date, or at such other date as Seller and Purchaser may, in writing, advise
Escrow Agent, Escrow Agent shall deliver all funds then held in the escrow to
Seller.  However, if Purchaser has delivered an Affidavit of Seller's Default
to Escrow Agent, on or before the Closing Date, in substantially the form of
Schedule 2, subscribed and sworn to by Purchaser, specifying in detail the
default or defaults of Seller, then Escrow Agent shall not deliver the funds to
Seller, but shall continue to hold the funds until advised in writing by both
Seller and purchaser or until directed by judicial order to disburse the
funds."

8.   The Purchaser hereby directs the Escrow Agent that the funds together with
interest thereon (if any) that were (i) heretofore deposited with Escrow Agent
by Purchaser and (ii) subsequently directed to be returned to Purchaser
pursuant to the Termination, shall be held as, and shall constitute, the
Earnest Money, as provided in the Agreement and the Escrow Agreement.

9.   This Amendment may be executed by facsimile and in counterparts, each of
which shall be deemed an original, but all of which, when taken together shall
constitute one and the same instrument.

                          [EXECUTION PAGE TO FOLLOW]

     IN WITNESS WHEREOF, the parties have executed this Amendment as of the
date first set forth above.
