     Re:  Registration Statement on Form S-8 (Registration No. 333-56619): 
          Amended and Restated 1997 Equity and Performance Incentive Plan 
          --------------------------------------------------------------------

Ladies and Gentlemen:

     We have served as Maryland counsel to Great Lakes REIT, a Maryland real 
estate investment trust (the "Company"), in connection with certain matters 
of Maryland law arising out of the registration of 1,839,751 common shares 
(the "Shares") of beneficial interest, $.01 par value per share, of the 
Company ("Common Shares") covered by the above-referenced Registration 
Statement (the "Registration Statement"), under the Securities Act of 1933, 
as amended (the "1933 Act").  The Shares are to be issued by the Company 
pursuant to the Company's Amended and Restated 1997 Equity and Performance 
Incentive Plan (the "Plan").  Capitalized terms used but not defined herein 
shall have the meanings given to them in the Registration Statement.

     In connection with our representation of the Company, and as a basis for 
the opinion hereinafter set forth, we have examined originals, or copies 
certified or otherwise identified to our satisfaction, of the following 
documents (hereinafter collectively referred to as the "Documents"):

     1.   The Registration Statement, and all amendments thereto, filed with 
the Securities and Exchange Commission (the "Commission"), pursuant to the 
Securities Act of 1933, as amended (the "1933 Act"), and the related form of 
prospectus in the form in which it will be sent or given to employees of the 
Company in accordance with Rule 428(b)(1) under the 1933 Act;

     2.   The Amended and Restated Declaration of Trust of the Company (the 
"Declaration of Trust"), certified as of a recent date by the State 
Department of Assessments and Taxation of Maryland (the "SDAT");

     3.   The Bylaws of the Company, certified as of the date hereof by its 
Secretary;

     4.   Resolutions adopted by the Board of Trustees of the Company 
relating to (a) the approval of the Plan and (b) the issuance and 
registration of the Shares, certified as of the date hereof by the Secretary 
of the Company;

     5.   The Plan;

     6.   A specimen of the certificate evidencing Common Shares, certified 
as of the date hereof by the Secretary of the Company;

     7.   A certificate of the SDAT as to the good standing of the Company, 
dated as of a recent date;

     8.   A certificate executed by the Secretary of the Company, dated the 
date hereof; and

     9.   Such other documents and matters as we have deemed necessary or 
appropriate to express the opinion set forth in this letter, subject to the 
assumptions, limitations and qualifications stated herein.

     In expressing the opinion set forth below, we have assumed, and so far 
as is known to us there are no facts inconsistent with, the following:

     1.   Each individual executing any of the Documents, whether on behalf 
of such individual or another person, is legally competent to do so.

     2.   Each individual executing any of the Documents on behalf of a party 
(other than the Company) is duly authorized to do so.

     3.   Each of the parties (other than the Company) executing any of the 
Documents has duly and validly executed and  delivered each of the Documents 
to which such party is a signatory, and such party's obligations set forth 
therein are legal, valid and binding and are enforceable in accordance with 
all stated terms.

     4.   Any Documents submitted to us as originals are authentic.  Any 
Documents submitted to us as certified or photostatic copies conform to the 
original documents.  All signatures on all such Documents are genuine.  All 
public records reviewed or relied upon by us or on our behalf are true and 
complete.  All statements and information contained in the Documents are true 
and complete.  There has been no oral or written modification of or amendment 
to any of the Documents, and there has been no waiver of any provision of any 
of the Documents, by action or omission of the parties or otherwise.

     5.   The Shares will not be issued in violation of any restriction or 
limitation contained in the Declaration of Trust.

     The phrase "known to us" is limited to the actual knowledge, without 
independent inquiry, of the lawyers at our firm who have performed legal 
services in connection with the issuance of this opinion.

     Based upon the foregoing, and subject to the assumptions, limitations 
and qualifications stated herein, it is our opinion that:

     1.   The Company is a real estate investment trust duly formed and 
existing under and by virtue of the laws of the State of Maryland and is in 
good standing with the SDAT.

     2.   The Shares have been duly authorized for issuance pursuant to the 
Plan and, when and if issued and delivered against payment therefor and 
otherwise in the manner described in the Resolutions and the Plan, will be 
(assuming that upon any such issuance the total number of Common Shares 
issued and outstanding will not exceed the total number of Common Shares that 
the Company is then authorized to issue under the Declaration of Trust) 
validly issued, fully paid and nonassessable.

     The foregoing opinion is limited to the substantive laws of the State of 
Maryland and we do not express any opinion herein concerning any other law.  
We express no opinion as to compliance with any federal or state securities 
laws, including the securities laws of the State of Maryland.  We assume no 
obligation to supplement this opinion if any applicable law changes after the 
date hereof or if we become aware of any fact that might change the opinion 
expressed herein after the date hereof.
