Item 5.  Other Events.

Public Offering

    On December 18, 1997, Brandywine Realty Trust (the "Company") and 
Brandywine Operating Partnership, L.P. entered into an Underwriting Agreement 
(the "Underwriting Agreement") with Legg Mason Wood Walker, Incorporated (the 
"Underwriter") pursuant to which the Company agreed to sell to the 
Underwriter an aggregate of 751,269 common shares of beneficial interest, 
$.01 par value per share (the "Common Shares").  The Common Shares are to be 
sold pursuant to the Underwriting Agreement at a price to the public of 
$24.625 per share ($23.5169 per share after reduction for underwriting 
discounts and commissions).  The Underwriter intends to deposit the Common 
Shares with the trustee of Legg Mason REIT Trust December 1997 Series (the 
"Trust"), a registered unit investment trust under the Investment Company Act 
of 1940, as amended, in exchange for units of the Trust.

    The Underwriter is acting as sponsor and depositor of the Trust, and is 
therefor considered an affiliate of the Trust. Walter D'Alessio, a member of 
the Company's Board of Trustees, is President of Legg Mason Real Estate 
Services, Inc., a subsidiary of Legg Mason Inc., the parent of the 
Underwriter. In addition, the Underwriter has engaged, and may in the future 
engage, in investment banking activities on behalf of the Company and its 
affiliates for which customary compensation will be received.

    The net proceeds, less expenses estimated at $75,000, will be 
contributed by the Company to the Operating partnership, which will use such 
contribution to make additional acquisitions of office or industrial 
properties and for working capital purposes. Closing of the offering of 
Common Shares pursuant to the Underwriting Agreement is subject to customary 
closing conditions.

Property Acquisition

    As previously reported in a Current Report on Form 8-K filed with the 
Securities and Exchange Commission on December 17, 1997, the Company acquired 
an office property in Valley Forge, PA (the "PECO Building") from PECO Energy 
for a purchase price of $9.5 million. Mr. D'Alessio, a member of the 
Company's Board of Trustees, is a director of PECO Energy. A committee of the 
Board of Trustees, of which Mr. D'Alessio is not a participant, made the 
decision to purchase the PECO Building and negotiated the terms of the 
transaction.
