Exhibit 10.20

AMENDMENT TO PURCHASE AND SALE AGREEMENT

THIS AMENDMENT TO PURCHASE AND SALE AGREEMENT (this "Amendment") is made and
entered into effective as of the 29 day of July, 2013, by and between COUSINS
TIFFANY SPRINGS MARKETPLACE LLC and CP - TIFFANY SPRINGS INVESTMENTS LLC
(collectively, "Seller"), and AMERICAN REALTY CAPITAL IV, LLC ("Purchaser").

RECITALS

A.    Seller and Purchaser entered into that certain Purchase and Sale Agreement
(the "Sale Agreement") dated as of June 28, 2013, for the sale and purchase of
the Tiffany Springs MarketCenter project in Kansas City, Missouri, as more fully
described in the Sale Agreement.

B.    Seller and Purchaser desire to amend the Sale Agreement as hereinafter
provided.

C.All terms which are defined in the Sale Agreement shall have the same meaning
when used in this Amendment unless specifically provided herein to the contrary.

AGREEMENT

For and in consideration of the foregoing, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
Seller and Purchaser hereby agree as follows:

1.     Inspection Period. The definition of "Inspection Period" set forth in
Article 1 of the Sale Agreement is hereby deleted in its entirety and the
following substituted in lieu thereof:

""Inspection Period" means the period expiring at 5:00 P.M. Eastern Standard
Time on Thursday, August 1, 2013."

2.    Closing. Section 2.6 of the Sale Agreement is hereby deleted in its
entirety and the following substituted in lieu thereof:

"The consummation of the sale by Seller and purchase by Purchaser of the Asset
(the "Closing") will be held on any date on or before Wednesday, August 28, 2013
(the "Closing Date"). Either party shall have the right to extend the Closing
Date for up to thirty (30) days by delivery of written notice of such extension
to the other party and the Title Company on or before the date immediately
preceding the scheduled Closing Date. Once one party has exercised its right to
extend the Closing Date in accordance with this Section 2.6, the other party
shall not have the right to extend the Closing Date to be a date any later than
a total of thirty (30) days from the originally scheduled Closing Date, except
to the extent otherwise expressly set forth in this Agreement. In the event
Purchaser elects to extend the Closing Date pursuant to this Section 2.6,
Purchaser will deliver the

Exhibit 10.20

Second Additional Earnest Money to Escrow Agent in the same manner as the
Initial Earnest Money within three (3) Business Days after the date of delivery
of Purchaser's notice of the extension of the Closing Date, and it is agreed
that the Earnest Money will be non-refundable on the exercise by Purchaser of
such extension right pursuant to this Section 2.6 except (a) in the event of a
default by Seller, or (b) a termination of this Agreement as a result of a
casualty or condemnation pursuant to Article 7 or as a result of the failure of
Seller to deliver the Required Tenant Executed Estoppels by the Closing Date, as
so extended. In addition, if Purchaser extends the Closing Date pursuant to this
Section 2.6, Purchaser will no longer have an extension right pursuant to
Section 4.4(e), and Seller will not be required to obtain any updated Estoppel
Certificates from tenants to the extent those previously received by Seller and
provided to Purchaser are dated more than thirty (30) days prior to the Closing
Date as a result of such extension. The Closing will take place at an office in
the metropolitan Atlanta, Georgia area, or at such specific place, time and
Closing Date designated by Purchaser in a written notice to Seller not less than
three (3) Business Days prior to Closing. If Purchaser fails to give notice of
the Closing Date, the Closing will be at the offices of the Escrow Agent at 2:00
p.m. on the outside date for Closing as provided in this Agreement.
Notwithstanding the foregoing, Seller and Purchaser agree to cooperate with one
another to effect an escrow closing with the documents to be executed by each
party to be delivered to Escrow Agent or to another mutually acceptable escrow
agent so as to obviate the need for the representatives of Seller and Purchaser
to attend the Closing."

3.     Counterpart Execution. This Amendment may be executed in multiple
counterparts, which, when combined together, shall constitute an original of
this Amendment. In addition, facsimile or email signatures of the parties shall
be effective on all counterparts of this Amendment.

4.    Entire Agreement. This Amendment, together with the Sale Agreement,
embodies the entire agreement of the parties hereto, and incorporates all
previous correspondence or communications, whether written or oral. The Sale
Agreement, as amended by this Amendment, can only be further modified or varied
by written instrument subscribed to by all of the parties hereto.
