     This FIRST AMENDMENT TO UNSECURED REVOLVING CREDIT AGREEMENT (this
"Amendment") is made as of this 19th day of June, 1998 by and among GREAT LAKES

Administrative Agent, THE FIRST NATIONAL BANK OF CHICAGO ("First Chicago"),
individually and as Documentation Agent, DRESDNER BANK AG, NEW YORK AND GRAND

     A.   Borrower, Bank of America, First Chicago, Dresdner, US Bank and
LaSalle are parties to an Unsecured Revolving Credit Agreement dated as of April
6, 1998 (the "Original Credit Agreement").  All capitalized terms used in this
Amendment and not otherwise defined herein shall have the meanings ascribed to
such terms in the Original Credit Agreement.

     B.   Pursuant to the terms of the Original Credit Agreement, the Lenders
agreed to provide Borrower with a revolving credit facility in an aggregate
principle amount of up to $150,000,000.  The parties hereto desire to amend the
Original Credit Agreement in order to, among other things, modify certain
financial covenants contained therein.

     NOW, THEREFORE, in consideration of the foregoing Recitals and for other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

                                      AGREEMENTS

     1.   The foregoing Recitals to this Amendment are hereby incorporated into
and made a part of this Amendment.

     2.   From and after the Effective Date, as defined below, the undersigned
agree that if Borrower falls out of compliance with the Pre-existing Covenants,
as defined below, then commencing as of the date the first such non-compliance
occurs and continuing only until the earlier of (i) 180 days after the Effective
Date, and (ii) the date on which Borrower comes back into compliance with both
(a) Consolidated Total Indebtedness is less than or equal to 50% of the Gross
Asset Value, and (b) Consolidated Unsecured Debt is less than or equal to 50% of
the Value of Unencumbered Assets (such covenants being referred to jointly, as
the "Pre-existing Covenants"):

          a)   Section 7.2 of the Original Credit Agreement shall be deemed to
          have been deleted in its entirety and replaced with the following:

               "7.2 MAXIMUM CONSOLIDATED LEVERAGE RATIO.  As 


<PAGE>

               of the end of any fiscal quarter, permit Consolidated Total
               Indebtedness to exceed 55% of The Gross Asset Value."

          b)   Section 7.5 of the Original Credit Agreement shall be deemed to
          have been deleted in its entirety and replace with the following:

               "7.5 MAXIMUM UNENCUMBERED ASSET COVERAGE RATIO.  As of the end of
               any fiscal quarter, permit Consolidated Unsecured Debt to exceed
               55% of the Value of Unencumbered Assets."

From and after the earlier of (a) 180 days after the Effective Date, and (b) the
date on which Borrower comes back into compliance with the Pre-existing
Covenants, all of the provisions of this Section 2 shall be automatically null
and void.

     3.   The "Effective Date" shall be the date on which all of the following
conditions shall have been fulfilled (or waived by the Lenders):

          a)   no Default or Event of Default then exists;

          b)   Borrower shall have executed and delivered, or caused to be
          executed and delivered, to Administrative Agent (i) a certificate
          dated as of the Effective Date signed by Borrower and Great Lakes
          REIT, Inc. ("General Partner") representing and warranting that (w)
          the Loan Documents are then in full force and effect and that, to the
          best of their knowledge, Borrower and General Partner then have no
          defenses or offsets to, or claims or counterclaims relating to, their
          obligations under the Loan Documents; (x) each of the representations
          and warranties contained in the Original Credit Agreement are true and
          correct, as and to the extent set forth in the Original Credit
          Agreement, (y) no Default or Event of Default has occurred and is
          continuing under the Loan Documents; and (z) no change in the
          financial condition of Borrower or the General Partner that would have

          certificate or certificates dated as of the Effective Date signed by a
          Qualified Officer of Borrower and each Guarantor that no changes have
          been made to the organizational documents or incumbency certificate of
          the Borrower or such Guarantor since the date of the Original Credit
          Agreement (or attaching certified copies of such changes); and (iii)
          opinions of counsel regarding the due authorization and enforceability
          of this Amendment and each Amendment to Guaranty, together with
          supporting resolutions and other evidence of authority, all
          satisfactory to the Administrative Agent;

          c)   Each Guarantor shall have executed and delivered to
          Administrative Agent a First Amendment to Guaranty in the form
          attached hereto as EXHIBIT A.

          d)   Borrower shall have paid to Administrative Agent the fees
          specified in the side letter of even date herewith between Borrower
          and Administrative Agent.

     If the Effective Date has not occurred by June 30, 1998, either Borrower or
Administrative Agent may elect to terminate this Amendment whereupon this
Amendment and all First Amendments to Guaranty shall have no further force or
effect and the Original Credit Agreement and Guaranties shall continue as if
such amendments have not been executed.

     4.   From and after the Effective Date, and continuing only until the
earlier of (i) 180 days after the Effective Date, and (ii) the date on which
Borrower comes into compliance with the Pre-existing Covenants, Section 2.6 of
the Original Credit Agreement shall be amended by deleting the table contained
