Exhibit 99.1

GREAT LAKES REIT REPORTS $0.11 EPS AND $0.44 FFO PER
COMMON SHARE FOR SECOND QUARTER 2003

Great Lakes REIT Second Quarter Highlights

OAK BROOK, ILLINOIS, August 7, 2003 - Great Lakes REIT (NYSE: GL), a real estate investment trust which holds a portfolio of Midwestern office and medical office properties, today announced second quarter 2003 net income of $1.8 million, or $0.11 per common share, and funds from operations (FFO) of $7.0 million, or $0.44 per common share. This compares to net income of $5.2 million, or $0.31 per common share, which included gain on sale of properties of $1.0 million, and FFO of $9.1 million or $0.55 per common share, for the second quarter of 2002. Results for the quarter ended June 30, 2003 were reduced due to one-time costs associated with the termination of certain employee share loans in the amount of $0.5 million, or $0.03 per common share. FFO represents a non-GAAP (generally accepted accounting principles) financial measure. A table reconciling FFO to the GAAP measure the Company believes to be most directly comparable, net income applicable to common shares, is included in this release. Although not a GAAP measure, the Company believes that the inclusion of information regarding funds from operations (FFO) provides important information to shareholders and potential investors. The GAAP measure, net income applicable to common shares, includes depreciation and amortization expenses, gains or losses on property sales and minority interests. In presenting FFO, the Company eliminates substantially all of these items in order to provide an indication of the results from the Company’s property operations. FFO is a widely recognized measure in the Company’s business and is presented by nearly all publicly traded REITs. The Company’s calculation of FFO may differ from the methodology for calculating FFO utilized by other real estate companies.

For the six months ended June 30, 2003, the Company reported net income of $4.5 million, or $0.28 per common share, compared to $9.4 million, or $0.57 per common share, for the comparable period of 2002 (including $1.0 million of gain on sale of properties for the six months ended June 30, 2002). There were no property sales during the six months ended June 30, 2003. Funds from operations totaled $14.9 million, or $0.92 per common share, for the six months ended June 30, 2003, as compared to FFO of $18.1 million, or $1.10 per common share for the comparable period of 2002. Results for the six months ended June 30, 2003 were reduced due to one-time costs associated with the termination of certain employee share loans in the amount of $0.5 million, or $0.03 per common share.

“The level of leasing activity, while challenging during the first six months of 2003, was somewhat better than expectations. Year to date we have averaged 40,000 square feet per month of new leases against a budget of 30,000 square feet per month. However, we expect that the leasing environment in our markets will remain difficult during the second half of 2003 and we continue to expect 30,000 square feet per month of new leasing for second half of 2003” commented Dick May, Great Lakes REIT’s Chairman and CEO. “The good news is, after averaging 20% per year average lease expirations over the last 3 years, our expiring leases average only 13% per year over the next 3 years. In addition, after 11 consecutive quarters of declining occupancies in our markets, occupancies improved by 0.2% since the first quarter”.

Based on current market conditions, the Company expects earnings per common share in the range of $0.55 to $0.70 and 2003 FFO per common share in the range of $1.70 to $1.80. This guidance assumes continued softness in the economy and office markets in which the Company operates. The Company does not anticipate acquiring any additional properties during the remainder of 2003 and, accordingly, has revised its guidance for 2003.

Portfolio Performance

Total revenues increased by 6% to $26.9 million in the second quarter of 2003 from $25.5 million in last year’s second quarter. Revenues increased primarily due to the acquisition of eight medical office properties on October 1, 2002. Same store sales decreased 17% (cash basis) for the three months ended June 30, 2003, as compared to the second quarter of 2002 primarily as a result of the decline in occupancy quarter over quarter.

Total revenues increased by $3.8 million, or 7.6%, to $54.0 million for the six months ended June 30, 2003, from $50.2 million for the comparable period of 2002. Revenues increased primarily due to the acquisition of eight medical office properties on October 1, 2002. Same store sales decreased 14.5% (cash basis) for the six months ended June 30, 2003, as compared to the six months ended June 30, 2002, primarily as a result of the decline in occupancy.

EBITDA decreased $1.3 million, or 5%, to $26.5 million for the six months ended June 30, 2003, as compared to $27.8 million for the comparable period in 2002. Cash provided by operating activities decreased slightly to $15.4 million for the six months ended June 30, 2003, from $15.6 million for the comparable period of 2002. Cash flow from operations for the six months ended June 30, 2003, slightly exceeded common and preferred share dividends paid for the same period.

EBITDA, a non-GAAP financial measure, represents net income before allocation to minority interests plus interest expense, federal income tax expense (if any) and depreciation and amortization expense. A table reconciling EBITDA to the GAAP measure the Company believes to be directly comparable, cash provided by operating activities, is included in this release. EBITDA is presented solely as a supplemental disclosure because the Company believes it provides useful information regarding the Company’s ability to service or incur debt. Because all companies do not calculate EBITDA the same way, the presentation of EBITDA may not be comparable to similarly titled measures of other companies.

Balance Sheet, Market Value and Liquidity

EBITDA coverage of interest expense was 3.0 times for the six months ended June 30, 2003 as compared to 3.7 times for the same period of 2002 and EBITDA coverage of interest plus preferred dividends was 2.5 times for the six months ended June 30, 2003 as compared to 3.0 times for the same period of 2002. Cash provided by operating activities (before interest expense) coverage of interest expense was 2.7 times for the six months ended June 30, 2003 as compared to 3.0 times for the comparable period of 2002. Cash provided by operating activities (before interest expense) coverage of interest expense plus preferred dividends was 2.3 times for the six months ended June 30, 2003 as compared to 2.5 times for the comparable period of 2002.

The Company has provided EBITDA and the related non-GAAP coverage ratios as supplemental disclosure because the Company believes such disclosure provides useful information regarding the Company’s ability to service or incur debt. Included with the reconciliation of EBITDA to the GAAP measure the Company believes to be directly comparable, cash provided by operating activities, are the coverage calculations for EBITDA coverage of interest expense, EBITDA coverage of interest plus preferred dividends, cash provided by operating activities (before interest expense) coverage of interest expense and cash provided by operating activities (before interest expense) coverage of interest expense plus preferred dividends.

The Company had $315.0 million of total debt outstanding at June 30, 2003. The interest rate on approximately 94% of this debt was fixed at an weighted average interest rate of 5.76%. At June 30, 2003, Great Lakes REIT had $45 million available for future borrowings under two secured lines of credit that the Company utilizes for acquisitions, development activities, capital improvements, tenant improvements, leasing costs and working capital needs.

Dividends

In May, June and July 2003, the Company paid regular monthly cash dividends of $0.135 per common share.

Leasing For the quarter ended June 30, 2003, the Company signed 124,000 square feet of new leases bringing the total for the year to 241,000 square feet. Net rental rates on new leases and leases renewed for the quarter were 9% lower than net rents on the expiring leases.

As expected, the occupancy rate for the Company’s portfolio of properties declined to 80.2% at July 1, 2003 from 80.9% at April 1, 2003. The Company believes that the trend of vacancy increases is slowing, but the Company anticipates that the difficult leasing environment that currently exists in its markets will persist throughout 2003.

At July 1, 2003, Great Lakes REIT had 497,000 square feet of leases, or 8% of the portfolio, expiring during the balance of 2003. The Company currently expects to retain or renew 240,000 to 260,000 square feet of the remaining 497,000 square feet of leases rolling over during 2003. Although the Company has leased approximately 40,000 square feet of new space per month through June 30, it anticipates it will average 30,000 per month of new leasing activity for the balance of 2003, basically the same level as was experienced in the very difficult environment of 2002. Based on the tenant retention and new leasing activity expectations noted above, the Company expects that average portfolio occupancy during 2003 will be in the range of 79% to 80%. Occupancy at January 1, 2004 is expected to be in the range of 77% to 79% assuming no significant tenant defaults occur during the remainder of the year.

Lease expirations for the years 2001, 2002 and 2003 averaged approximately 20% of total year end portfolio square footage each year, while lease expirations for 2004, 2005 and 2006 are expected to be 16%, 13% and 9% of total portfolio square footage, respectively. The Company believes the economic impact of new leasing activity will be less pronounced over the next several years.

Property Dispositions

On July 8, 2003, the Company sold its properties located at 165 and 175 Hansen Court, Wood Dale, Illinois, for a contract price of $3.9 million. The gain on sale of properties for this transaction of approximately $1.7 million will be recognized in the third quarter of 2003. The proceeds from sale were used for retirement of long-term debt ($2.3 million) with the balance for working capital ($1.5 million).

Tenant Credit Issues As of July 1, 2003, several tenants were in default under their leases for failure to make rent payments. Several other tenants that are not currently in default are experiencing financial difficulties which may lead to lease defaults. These tenant defaults may adversely impact the Company’s results of operations in 2003.

Legion Insurance Company, which leases 58,000 square feet of space at Milwaukee Center and represented 1.53% of the Company’s aggregate portfolio annualized base rent as of December 31, 2002, was placed in rehabilitation by the Pennsylvania Department of Insurance on April 1, 2002. After completing its review, the Pennsylvania Department of Insurance has recommended to the Commonwealth Court that Legion Insurance Company be liquidated. The Commonwealth Court approved the recommendation of the Pennsylvania Department of Insurance on July 28, 2003. Based on currently available information, the Company believes it is more likely than not that Legion will fulfill all terms of its lease in 2003. Legion Insurance Company is current on its rental payments to date. The Legion lease specifies a termination date of February 28, 2006.

Alternatives to Improve Shareholder Value

The Company’s Board of Trustees has engaged a real estate advisor and an investment banker to assist it in analyzing alternatives to improve shareholder value. These alternatives may include a sale of some or all of the Company’s properties, or a business combination or other similar transaction. Such activities are ongoing, and there can be no assurance that any such transaction will occur.

Non-GAAP Financial Measures

Although not a GAAP measure, the Company believes that the inclusion of information regarding funds from operations (FFO) provides important information to shareholders and potential investors. The GAAP measure, net income applicable to common shares, includes depreciation and amortization expenses, gains or losses on property sales and minority interests. In presenting FFO, the Company eliminates substantially all of these items in order to provide an indication of the results from the Company’s property operations. FFO is a widely recognized measure in the Company’s business and is presented by nearly all publicly traded REITs. The Company’s calculation of FFO may differ from the methodology for calculating FFO utilized by other real estate companies.

EBITDA and Cash Provided by Operating Activities and Related Coverage Ratios March 31, 2003 (dollars in thousands)

EBITDA, a non-GAAP financial measure, represents net income before allocation to minority interests plus interest expense, federal income tax expense (if any) and depreciation and amortization expense.

EBITDA is not intended to represent cash flow for the period, is not presented as a an alternative to operating income as an indicator of operating performance, should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP and is not indicative of operating income or cash provided by operating activities as determined under GAAP.

EBITDA is presented solely as a supplemental disclosure because the Company believes it provides useful information regarding the Company’s ability to service or incur debt. Because all companies do not calculate EBITDA the same way, the presentation of EBITDA may not be comparable to similarly titled measures of other companies.

The Company believes that cash provided by operating activities is the financial measure calculated and presented in accordance with GAAP that is most directly comparable to EBITDA. The following is a reconciliation of EBITDA to cash provided by operating activities for each of the periods for which EBITDA is presented in this earnings release:

The Company has included the coverage calculations for EBITDA coverage of interest expense and EBITDA coverage of interest plus preferred dividends, which are non-GAAP financial measures, as well as the GAAP ratio that the Company believes to be most directly comparable, cash provided by operating activities (before interest expense) coverage of interest expense and cash provided by operating activities (before interest expense) coverage of interest expense plus preferred dividends. The Company has provided both calculations so that investors may evaluate both the non-GAAP and GAAP ratios together, and the Company is providing such ratios as supplemental disclosure with respect to liquidity because the Company believes such ratios provide useful information regarding the Company’s ability to service or incur debt.

Great Lakes REIT
Reconciliation of Same Store Net Operating Income to Income Before Allocation
    to Minority Interests (unaudited)
(Dollars in thousands)

     The Company provides same store net operating income which is the net operating income of properties owned in both the three and six months ended June 30, 2003 and 2002. Same store net operating income is considered a non-GAAP financial measure because it does not include depreciation and amortization, interest expense and general and administrative expenses. The Company provides same store net operating income as it allows investors to compare the results of property operations for the three and six months ended June 30, 2003 and 2002. The Company also provides a reconciliation of these amounts to the most comparable GAAP measure, income before allocation to minority interests.
