Exhibit 10.1


                            FOURTH AMENDMENT TO THE
             AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP
                           OF GREAT LAKES REIT, L.P.


     This Fourth Amendment to the Amended and Restated Agreement of Limited
Partnership of Great Lakes REIT, L.P., a Delaware limited partnership (the
"Partnership"), is made and entered into as of the 23rd day of December, 1998 by
Great Lakes REIT, a Maryland real estate investment trust ("GLREIT").

                                   RECITALS:

     WHEREAS, GLREIT is the sole general partner of the Partnership, the
business and affairs of which are conducted in accordance with the terms and
conditions of the Agreement of Limited Partnership of the Partnership dated
September 27, 1996, as amended and restated by the Amended and Restated
Agreement of Limited Partnership dated as of December 19, 1996 and as further
amended by the First Amendment to the Amended and Restated Agreement of Limited
Partnership of the Partnership dated February 6, 1997, the Second Amendment to
the Amended and Restated Agreement of Limited Partnership of the Partnership
dated February 10, 1997 and the Third Amendment to the Amended and Restated
Agreement of Limited Partnership of the Partnership dated May 22, 1998
(collectively, the "Partnership Agreement"); and

     WHEREAS, Sections 4.2(c) and 13.1(b)(iii) of the Partnership Agreement
expressly provide that the General Partner shall amend the Partnership Agreement
to set forth the designations, rights, powers and duties, and preferences of the
Preferred Units in one or more Preferred Unit Designations without the consent
of the Limited Partners; and

     WHEREAS, the Partnership Agreement provides that a holder of such 
Preferred Units shall have such rights to the allocations of Profits and 
Losses as specified in Article VI of the Partnership Agreement and to 
distributions pursuant to Section 5.1 of the Partnership Agreement;

     WHEREAS, in connection with GLREIT's issuance and sale on the date 
hereof of 1,500,000 9 3/4% Series A Cumulative Redeemable Preferred Shares of 
Beneficial Interest, $.01 par value per share ("Series A Preferred Shares"), 
and GLREIT's contribution to the Partnership of the Required Funds obtained 
from the issuance and sale of the Series A Preferred Shares, the Partnership 
hereby assumes the expenses (including the applicable underwriter discounts) 
incurred by GLREIT in connection with raising such Required Funds and issues 
to GLREIT Preferred Units to reflect GLREIT's contribution of such funds, 
which Preferred Units have the economic rights, including, distribution, 
redemption and conversion rights and sinking funds provisions, set forth 
herein; and

     WHEREAS, GLREIT, as the sole general partner of the Partnership, desires to
amend the Partnership Agreement to reflect the issuance of the Series A
Preferred Units and to set forth the applicable designation, rights, powers,
duties and preferences thereof;

     NOW THEREFORE, the Partnership Agreement shall be amended as follows:

     1.   A series of Preferred Units, designated the 9 3/4% Series A Cumulative
          Redeemable Preferred Units (the "Series A Preferred Units"), is hereby
          established. The number of authorized Series A Preferred Units is
          1,500,000.



     2.   The Required Funds obtained from the sale of the Series A Preferred
          Shares shall be contributed to the Partnership as Contributed Funds.

     3.   The Series A Preferred Units shall, with respect to distribution
          rights and rights upon liquidation, dissolution or winding up of the
          Partnership, rank (a) senior to all classes or series of Partnership
          Units, and to all Units issued by the Partnership ranking junior to
          such Series A Preferred Units; (b) on a parity with all other Units
          issued by the Partnership, the terms of which specifically provide
          that such equity securities rank on a parity with the Series A
          Preferred Units; and (c) junior to all Units issued by the
          Partnership, the terms of which specifically provide that such equity
          securities rank senior to the Series A Preferred Units.

     4.   DISTRIBUTIONS.  Section 5.1 of the Partnership agreement is hereby
amended to incorporate the following distribution provisions relating to the 
Series A Preferred Units:

          a.   Holders of the then outstanding Series A Preferred Units shall be
               entitled to receive, when and as authorized by the General
               Partner, out of Available Cash Flow, cumulative preferential cash
               distributions at the rate of  9 3/4% of the $25.00 liquidation
               preference per annum (equivalent to a fixed annual amount of
               $2.4375 per Series A Preferred Unit). Such distributions shall be
               cumulative from the first date on which any Series A Preferred
               Units are issued and shall be payable quarterly in arrears on or
               before March 1, June 1, September 1 and December 1 of each year
               or, if not a business day, the next succeeding business day
               (each, a "Series A Partnership Distribution Payment Date"). The
               first distribution, which will be paid on March 1, 1999, will
               cover the period from the date of issuance of the Series A
               Preferred Units to March 1, 1999. Such distribution and any
               distribution payable on the Series A Preferred Units for any
               partial distribution period will be computed on the basis of a
               360-day year consisting of twelve 30-day months. Distributions
               will be payable to holders of record as they appear in the
               records of the Partnership at the close of business on the
               applicable record date, which shall be the fifteenth day of the
               calendar month immediately preceding the calendar month in which
               the applicable Series A Partnership Distribution Payment Date
               falls or on such other date designated by the General Partner as
               the record date for the payment of distributions on the Series A
               Preferred Shares that is not more than 30 nor less than 10 days
               prior to such Partnership Distribution Payment Date (each, a
               "Series A Partnership Record Date").

          b.   No distributions on Series A Preferred Units shall be authorized
               by the General Partner or paid or set apart for payment by the
               General Partner at such time as the terms and provisions of
               any agreement of the Partnership, including any agreement
               relating to its indebtedness, prohibits such authorization,
               payment or setting apart for payment or provides that such
               authorization, payment or setting apart for payment would
               constitute a breach thereof or a default thereunder, or if such
               authorization or payment shall be restricted or prohibited by
               law.


                                      2


          c.   Notwithstanding the foregoing, distributions on the Series A
               Preferred Units shall accrue whether or not the terms and
               provisions set forth in Paragraph 4.b. hereof at any time
               prohibit the current payment of distributions, whether or not the
               Partnership has Available Cash Flow, whether or not there are
               funds legally available for the payment of such distributions and
               whether or not such distributions are declared. Accrued but
               unpaid distributions on the Series A Preferred Units will
               accumulate as of the Series A Partnership Distribution Payment
               Date on which they first become payable.

          d.   Except as provided in Paragraph 4.e. below, no distributions will
               be declared or paid or set apart for payment on any Partnership
               Units or any other series of Preferred Units ranking, as to
               distributions, on a parity with or junior to the Series A
               Preferred Units (other than a distribution in the Partnership
               Units or in any other class of Units ranking junior to the Series
               A Preferred Units as to distributions and upon liquidation) for
               any period unless full cumulative distributions have been or
               contemporaneously are declared and paid or declared and a sum
               sufficient for the payment thereof is set apart for such payment
               on the Series A Preferred Units for all past distribution periods
               and the then current distribution period.

          e.   When distributions are not paid in full (and a sum sufficient for
               such full payment is not so set apart) upon the Series A
               Preferred Units and any other series of Preferred Units ranking
               on a parity as to distributions with the Series A Preferred
               Units, all distributions declared upon the Series A Preferred
               Units and any other series of Preferred Units ranking on a parity
               as to distributions with the Series A Preferred Units shall be
               declared pro rata so that the amount of distributions declared
               per Series A Preferred Units and such other series of Preferred
               Units shall in all cases bear to each other the same ratio that
               accrued distributions per Series A Preferred Units and such other
               series of Preferred Units (which shall not include any accrual in
               respect of unpaid distributions for prior distribution periods if
               such Preferred Units do not have a cumulative distribution) bear
               to each other. No interest, or sum of money in lieu of interest,
               shall be payable in respect of any distribution payment or
               payments on Series A Preferred Units that may be in arrears.

          f.   Except as provided in the immediately preceding paragraph, unless
               full cumulative distributions on the Series A Preferred Units
               have been or contemporaneously are declared and paid or declared
               and a sum sufficient for the payment thereof is set apart for
               payment for all past distribution periods and the then current
               distribution period, no distributions (other than in Partnership
               Units or other Units ranking junior to the Series A Preferred
               Units as to distributions and upon liquidation) shall be declared
               or paid or set aside for payment, nor shall any other
               distribution be declared or made, upon the Partnership Units or
               any other Units of the Partnership ranking junior to or on a
               parity with the Series A Preferred Units as to distributions or
               upon liquidation, nor shall any Partnership 


                                      3


               Units, or any other Units of the Partnership ranking junior to 
               or on a parity with the Series A Preferred Units as to 
               distributions or upon liquidation be redeemed, purchased or 
               otherwise acquired for any consideration (or any monies be 
               paid to or made available for a sinking fund for the 
               redemption of any such shares) by the Partnership (except by 
               conversion into or exchange for other Units of the Partnership 
               ranking junior to the Series A Preferred Units as to 
               distributions and upon liquidation)

          g.   Holders of the Series A Preferred Units shall not be entitled to
               any distribution, whether payable in cash, property or shares in
               excess of full cumulative distributions on the Series A Preferred
               Units as described above.  Any distribution payment made on the
               Series A Preferred Units shall first be credited against the
               earliest accrued but unpaid distribution due with respect to such
               shares that remains payable. 

     5.   LIQUIDATION PREFERENCE.

          a.   Upon any voluntary or involuntary liquidation, dissolution or
               winding up of the affairs of the Partnership, the holders of
               Series A Preferred Units then outstanding are entitled to be paid
               out of the assets of the Partnership legally available for
               distribution to its unitholders a liquidation preference of
               $25.00 per share, plus an amount equal to any accrued and unpaid
               distributions to the date of payment, before any distribution of
               assets is made to holders of Partnership Units or any other class
               or series of Units of the Partnership that ranks junior to the
               Series A Preferred Units as to liquidation rights.

          b.   In the event that, upon such voluntary or involuntary
               liquidation, dissolution or winding up, the available assets of
               the Partnership are insufficient to pay the amount of the
               liquidating distributions on all outstanding Series A Preferred
               Units and the corresponding amounts payable on all shares of
               other classes or series of Units of the Partnership ranking on a
               parity with the Series A Preferred Units in the distribution of
               assets, then the holders of the Series A Preferred Units and all
               other such classes or series of Units shall share ratably in any
               such distribution of assets in proportion to the full liquidating
               distributions to which they would otherwise be respectively
               entitled.

          c.   After payment of the full amount of the liquidating distributions
               to which they are entitled, the holders of Series A Preferred
               Units will have no right or claim to any of the remaining assets
               of the Partnership.

          d.   Written notice of any such liquidation, dissolution or winding up
               of the Partnership, stating the payment date or dates when, and
               the place or places where, the amounts distributable in such
               circumstances shall be payable, shall be given by first class
               mail, postage pre-paid, not less than 30 nor more than 60 days
               prior to the payment date stated therein, to each record holder
               of the Series A Preferred Units (other than the General 


                                      4


               Partner) at the respective addresses of such holders as the 
               same shall appear on the unit transfer records of the 
               Partnership.

          e.   In determining whether a distribution (other than upon voluntary
               or involuntary liquidation), by distribution, redemption or other
               acquisition of units of the Partnership or otherwise, is
               permitted under Delaware law, amounts that would be needed, if
               the Partnership were to be dissolved at the time of the
               distribution, to satisfy the preferential rights upon dissolution
               of holders of Series A Preferred Units will not be added to the
               Partnership's total liabilities.

     6.   REDEMPTION.

          a.   RIGHT OF OPTIONAL REDEMPTION. The Series A Preferred Units are
               not redeemable prior to December 16, 2003. On and after
               December 16, 2003, the Partnership, at its option and upon not
               less than 30 nor more than 60 days written notice, may redeem the
               Series A Preferred Units, in whole or in part, at any time or
               from time to time, for cash at a redemption price of $25.00 per
               Series A Preferred Unit, plus all accrued and unpaid
               distributions thereon to the date fixed for redemption (except as
               provided in Section 5(c) below), without interest. If less than
               all of the outstanding Series A Preferred Units are to be
               redeemed, the Series A Preferred Units to be redeemed shall be
               selected pro rata (as nearly as may be practicable without
               creating fractional units) or by any other equitable method
               determined by the Partnership.

          b.   LIMITATIONS ON REDEMPTION.

               i.   The redemption price of the Series A Preferred Units (other
                    than the portion thereof consisting of accrued and unpaid
                    distributions) is payable solely out of the contribution 
                    to the Partnership by GLREIT of the sale proceeds of other
                    shares of beneficial interest of GLREIT, which may include
                    other series of Preferred Shares, and from no other
                    source. For purposes of the preceding sentence, "shares of
                    beneficial interest" means any equity securities (including
                    Common Shares and Preferred Shares), shares, interest,
                    participation or other ownership interests (however
                    designated) and any rights (other than debt securities
                    convertible 


                                      5


                    into or exchangeable for equity securities) or options to 
                    purchase any of the foregoing.

               ii.  Unless full cumulative distributions on all Series A
                    Preferred Units shall have been or contemporaneously are
                    declared and paid or declared and a sum sufficient for the
                    payment thereof set apart for payment for all past
                    distribution periods and the then current distribution
                    period, no Series A Preferred Units shall be redeemed unless
                    all outstanding Series A Preferred Units are simultaneously
                    redeemed, and the Partnership shall not redeem any Series A
                    Preferred Units (except by exchange for Units of the
                    Partnership ranking junior to the Series A Preferred Units
                    as to distributions and upon liquidation); PROVIDED,
                    HOWEVER, that the foregoing will not prevent the 
                    redemption of Series A Preferred Units pursuant to a
                    purchase or exchange offer made on the same terms to holders
                    of all outstanding Series A Preferred Units.

          c.   RIGHTS TO DISTRIBUTIONS ON SHARES CALLED FOR REDEMPTION.
               Immediately prior to any redemption of Series A Preferred Units,
               the Partnership shall pay, in cash, any accumulated and unpaid
               distributions through the redemption date, unless a redemption
               date falls after a Series A Partnership Record Date and prior to
               the corresponding Series A Partnership Distribution Payment Date,
               in which case each holder of Series A Preferred Units at the
               close of business on such Series A Partnership Record Date shall
               be entitled to the distribution payable on such shares on the
               corresponding Series A Partnership Distribution Payment Date
               notwithstanding the redemption of such shares before such Series
               A Partnership Distribution Payment Date. Except as provided
               above, the Partnership will make no payment or allowance for
               unpaid distributions, whether or not in arrears, on Series A
               Preferred Units that are redeemed.

          d.   PROCEDURES FOR REDEMPTION.

               i.   Notice of redemption will be mailed by the Partnership,
                    postage prepaid, not less than 30 nor more than 60 days
                    prior to the redemption date, addressed to the respective
                    holders of record of the Series A Preferred Units (other
                    than the General Partner) to be redeemed at their respective
                    addresses as they appear on the unit transfer records of the
                    Partnership.  No failure to give such notice or any defect
                    therein or in the mailing thereof shall affect the validity
                    of the proceedings for the redemption of any Series A
                    Preferred Units except as to the holder to whom notice was
                    defective or not given.

               ii.  Such notice shall state: (A) the redemption date; (B) the
                    redemption price; (C) the number of Series A Preferred Units
                    to be 


                                      6


                    redeemed; (D) the place or places where the Series A
                    Preferred Units are to be surrendered for payment of the
                    redemption price; and (E) that distributions on the units
                    to be redeemed will cease to accrue on such redemption date.
                    If less than all of the Series A Preferred Units held by any
                    holder are to be redeemed, the notice mailed to such holder
                    shall also specify the number of Series A Preferred Units
                    held by such holder to be redeemed.

               iii. If notice of redemption of any Series A Preferred Units has
                    been given and if the funds necessary for such redemption
                    have been set aside by the Partnership in trust for the
                    benefit of the holders of any Series A Preferred Units so
                    called for redemption, then from and after the redemption
                    date distributions will cease to accrue on such Series A
                    Preferred Units, such Series A Preferred Units shall no
                    longer be deemed outstanding and all rights of the holders
                    of such units will terminate, except the right to receive
                    the redemption price. Holders of Series A Preferred Units to
                    be redeemed shall surrender such Series A Preferred Units at
                    the place designated in such notice and, upon surrender in
                    accordance with said notice of the certificates evidencing
                    Series A Preferred Units so redeemed (properly endorsed or
                    assigned for transfer, if the Partnership shall so require
                    and the notice shall so state), such Series A Preferred
                    Units shall be redeemed by the Partnership at the redemption
                    price plus any accrued and unpaid distributions payable upon
                    such redemption. In case less than all the Series A
                    Preferred Units evidenced by any such certificate are
                    redeemed, a new certificate or certificates shall be issued
                    evidencing any unredeemed Series A Preferred Units without
                    cost to the holder thereof.

               iv.  The deposit of funds with a bank or trust corporation for
                    the purpose of redeeming Series A Preferred Units shall be
                    irrevocable except that:

                    (A)  the Partnership shall be entitled to receive from such
                         bank or trust corporation the interest or other
                         earnings, if any, earned on any money so deposited in
                         trust, and the holders of any shares redeemed shall
                         have no claim to such interest or other earnings; and

                    (B)  any balance of monies so deposited by the Partnership
                         and unclaimed by the holders of the Series A Preferred
                         Units entitled thereto at the expiration of two years
                         from the applicable redemption dates shall be repaid,
                         together with any interest or other earnings thereon,
                         to the Partnership, and after any such repayment, the
                         holders of the shares entitled to the funds so repaid
                         to the Partnership shall look 


                                      7


                         only to the Partnership for payment without interest 
                         or other earnings.

     7.   The Series A Preferred Units are not convertible into or exchangeable
          for any other property or securities of the Partnership.

     8.   Except as set forth above, no other provision of the Partnership
          Agreement shall be affected, amended or modified except to the extent
          necessary to conform to the above amendment.  Unless defined herein,
          all capitalized terms used herein shall have the definitions provided
