Revolving Credit Note Agreement among Grubb & Ellis Company (the "Company") and
The Prudential Insurance Company of America ("Prudential"), dated as of November
2, 1992 (as amended from time to time, the "Agreement"), pursuant to which
Prudential (i) purchased an aggregate of $10,000,000 in principal amount of the
Company's 9.90% Senior Notes due November 1, 1996 (the "Senior Notes") and an
aggregate of $10,000,000 in principal amount of the Company's 10.65%
Subordinated Payment-in-Kind Notes due November 1, 1999 (the "PIK Notes") and
(ii) agreed to make revolving credit loans to the Company in the aggregate
principal amount of $5,000,000.  Capitalized terms used herein and not defined
shall have the meanings given such terms in the Agreement.

                                    RECITALS

     A.  The Company has informed Prudential that the Company believes it will
need additional working capital to fulfill its financial plans.

consummation of the Rights Offering, Prudential has agreed, among other things,

such amendments, and hereafter neither the Company nor Prudential shall have any
liability under such provisions of the Preliminary Agreement or any such other
agreements; PROVIDED, HOWEVER, that nothing herein shall supersede, replace or
