Item 1.01 Entry into a Material Definitive Agreement

On October 3, 2025, Brandywine Operating Partnership, L.P., a Delaware limited partnership (the "Operating Partnership"), completed its offering and sale (the "Notes Offering") of $300 million in aggregate principal amount of its 6.125% Guaranteed Notes due 2031 (the "Notes"). The Notes Offering was made pursuant to the Operating Partnership's shelf registration statement on Form S-3 (File No. 333-270133) filed with the Securities and Exchange Commission (the "Commission") on February 28, 2023. The material terms of the Notes are described in the base prospectus dated February 28, 2023, as supplemented by a final prospectus supplement dated September 29, 2025.

The Notes were issued under the Indenture, dated as of October 22, 2004 (the "Original Indenture," and, as modified or supplemented from time to time, the "Indenture"), as supplemented by the First Supplemental Indenture dated as of May 25, 2005 (the "First Supplemental Indenture"), and the Third Supplemental Indenture dated as of April 5, 2011 (the "Third Supplemental Indenture"), among Brandywine Realty Trust, a Maryland real estate investment trust (the "Company"), the Operating Partnership and The Bank of New York Mellon (formerly known as The Bank of New York), as trustee.

The Notes bear interest at a rate of 6.125% per year. Interest is payable on the Notes semi-annually on January 15 and July 15 of each year, beginning on January 15, 2026.

The Notes are unsecured obligations of the Operating Partnership and will rank equally with all of its other unsecured unsubordinated indebtedness from time to time outstanding. The Notes will be effectively subordinated to the indebtedness and other liabilities of the consolidated subsidiaries of the Operating Partnership. The Company, which is the sole general partner of the Operating Partnership, has fully and unconditionally guaranteed payment of principal and interest on the Notes.

Prior to December 15, 2030 (one month prior to the Notes' maturity date) (the "Par Call Date"), the Operating Partnership may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Notes to be redeemed, plus in either case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

If certain events of default specified in the Indenture occur and are continuing with respect to a series of the Notes, the Trustee or the holders of not less than 25% in outstanding principal amount of a series of the Notes may declare the principal of and premium, if any, and accrued and unpaid interest on the Notes to be due and payable immediately by written notice thereof to the Operating Partnership and the Company (and to the Trustee if given by the holders).

The net proceeds from the Notes Offering amounted to approximately $296.3 million after deducting the underwriting discount and estimated transaction expenses relating to the Notes Offering and payable by the Operating Partnership and excluding accrued interest paid by the purchasers of the Notes. The Operating Partnership will use the net proceeds from the Notes Offering to repay its consolidated secured debt and for general corporate purposes, which may include the repayment, repurchase or other retirement of other indebtedness.

Affiliates of certain of the Underwriters, and the trustee under the indenture for the notes, are lenders and/or agents under the unsecured revolving credit facility. To the extent that the net proceeds from the offering are used to repay amounts that have been borrowed, may borrow or re-borrow in the future under the unsecured revolving credit facility and term loan facility, those lenders will receive a pro rata portion of any of the proceeds from this offering that are used to repay any such amounts.

The foregoing is a summary of the material terms and conditions of the Indenture and is not a complete discussion. Accordingly, the foregoing is qualified in its entirety by reference to the full text of the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture, and the Notes. The Original Indenture previously was filed with the Commission on October 22, 2004, as Exhibit 4.1 to the Company's Current Report on Form 8-K, and is incorporated into this Item 1.01 by this reference. The First Supplemental Indenture previously was filed with the Commission on May 26, 2005, as Exhibit 4.1 to the Company's Current Report on Form 8-K, and is incorporated into this Item 1.01 by this reference. The Third Supplemental Indenture previously was filed with the Commission on April 5, 2011, as Exhibit 4.1 to the Company's Current Report on Form 8-K, and is incorporated into this Item 1.01 by this reference. A form of Note is included in Exhibit 4.1, to this Current Report on Form 8-K and are incorporated into this Item 1.01 by this reference.

[REVERSE OF NOTE]

**BRANDYWINE OPERATING PARTNERSHIP, L.P.** 

**6.125% Guaranteed Notes Due 2031** 

This Note is one of a duly authorized issue of securities of the Issuer (the "Securities"), issued or to be issued under and pursuant to an Indenture, dated as of October 22, 2004, as supplemented (the "Indenture"), among the Issuer, Brandywine Realty Trust, a Maryland real estate investment trust (the "Parent Guarantor"), and The Bank of New York Mellon, as Trustee (the "Trustee," which term includes any successor Trustee under the Indenture with respect to the series of Securities of which this Note is a part), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Issuer, the Parent Guarantor, the Trustee and the Holders of the Securities and the terms upon which the Securities are to be authenticated and delivered. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), and may otherwise vary as provided in the Indenture. This Note is one of a series of Securities designated as the "6.125% Guaranteed Notes due 2031" of the Issuer (the "Notes"), initially limited in aggregate principal amount to $300,000,000. The Issuer may, from time to time, without the consent of the Holders, issue and sell additional Securities ranking equally with the Notes and otherwise identical in all respects (except for their date of issuance, issue price and the date from which interest payments thereon will accrue) so that such additional Securities will be consolidated and form a single series with the Notes**.**

The Notes are fully and unconditionally guaranteed as to the due and punctual payment of principal of and Make-Whole Amount, if any, and interest on the Notes by the Parent Guarantor.

All terms used in this Note which are defined in the Indenture will have the meanings assigned to them in the Indenture.

Prior to December 15, 2030 (one month prior to their maturity date) (the "Par Call Date"), the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (the "Redemption Price") (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the date fixed for redemption (the "Redemption Date") (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points less (b) interest accrued to the Redemption Date, and (ii) 100% of the principal amount of the Notes to be redeemed (the "Make-Whole Amount"), plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

------

The Issuer's actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption shall be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary's procedures) at least 10 days but not more than 60 days before the Redemption Date to the Holder of Notes to be redeemed.

In the case of a partial redemption, selection of the Notes in definitive form for redemption shall be made by lot. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note shall state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder of the Note upon surrender for cancellation of the original Note. For so long as the notes are held by DTC (or another Depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary, and may be made on a pro rata pass-through distribution of principal basis.

Unless the Issuer defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on this Note or portions thereof called for redemption.

The following terms have the meanings specified below:

"Treasury Rate" means, with respect to any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily)—H.15" (or any successor designation or publication) ("H.15") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("H.15 TCM"). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the "Remaining Life"); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

------

If on the third Business Day preceding the redemption date H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.
