Item 1.01 Entry into a Material Definitive Agreement.

     (i) On December 21, 2004, the Compensation Committee of our Board of Trustees awarded to one of our non-management Trustees, Wyche Fowler, 747 “restricted” common shares in payment of a pro rata portion of his Trustee compensation. The form of restricted share agreement with Mr. Fowler is attached to this Current Report on Form 8-K as Exhibit 10.1. Other than the date of the award agreement and the number of shares covered by the award agreement, the form of the award agreement is identical to the form of award agreement attached to our Quarterly Report on Form 10-Q filed on August 6, 2004 that we entered into with our other non-management Trustees.

     (ii) On December 21, 2004, our Board of Trustees adopted the Executive Deferred Compensation Plan (the “Plan”), which will become effective January 1, 2005. Under the Plan, Brandywine Realty Trust will provide employees and non-employee trustees who are eligible to participate in the Plan with the opportunity to defer compensation. The Plan continues the deferral opportunity that we previously offered under a deferred compensation adopted in 2000. In connection with new requirements imposed on deferred compensation plans by the American Jobs Creation Act of 2004 and the regulations to be issued thereunder ("AJCA"), we froze the prior plan to new deferrals and adopted the Plan, which is intended to comply with the AJCA. The amount of compensation to be deferred by each participating employee or non-employee trustee will be based on elections by each participant. Deferred compensation will be credited to participants’ account balances under the Plan. Account balances of employee participants will be credited with income, gains and losses based on the performance of investment funds that are made available for participant investment direction under the Plan. Participants will be eligible to receive distributions of the amounts credited to their account balances at a time or times established under the rules of the Plan on a basis consistent with applicable tax law principles. A copy of the Plan is attached as Exhibit 10.2 to this Current Report on Form 8-K.

Item 5.05 Amendments to the Registrant’s Code of Ethics, or waiver of a Provision of the Code of Ethics.

     In connection with its annual review of Board committee charters and our corporate governance principles, on December 21, 2004, our Board approved clarifying amendments to our Code of Business Ethics and Conduct. Together with our Board committee charters and Corporate Governance Principles, our revised Code of Business Conduct and Ethics (which we attach as Exhibit 14.1 to this Current Report on Form 8-K) may be found on our internet website at http://www.brandywinerealty.com.

Item 8.01 Other Events.

     We are filing, as Exhibit 99.1, a description of the material U.S. federal income tax consequences relating to the taxation of us as a REIT and the ownership and disposition of our common shares. This description replaces and supersedes prior descriptions of the material federal income tax treatment of us and our shareholders to the extent that they are inconsistent with the description contained in this Current Report on Form 8-K. The description of material U.S. federal

income tax consequences includes forward-looking statements. These forward-looking statements are identified by using words such as “anticipate”, “believe”, “intend”, “may be” and “will be” and similar words or phrases, or the negative thereof. Important factors that could cause actual results to differ materially from those reflected in such forward-looking statements include, among others, the factors discussed in the risk factors included in our Form 10-K for the year ended December 31, 2003. For all forward-looking statements contained herein, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Effective January 1, 2005

ARTICLE 1

PURPOSE

In recognition of the services provided by certain key employees, the Board of Trustees of Brandywine Realty Trust (the “Board”) has adopted the Brandywine Realty Trust Executive Deferred Compensation Plan, effective January 1, 2005 (the “Effective Date”).

Prior to the Effective Date, the Pre-2005 Brandywine Realty Trust Executive Deferred Compensation Plan (the “Pre-2005 EDCP”) was in effect. In order to preserve the favorable tax treatment available to deferrals under the Pre-2005 EDCP due to the American Jobs Creation Act of 2004, the regulations and Internal Revenue guidance issued thereunder (collectively, the “AJCA”), the Board froze the Pre-2005 EDCP with respect to amounts earned and vested on and after the Effective Date. Amounts earned and vested prior to the Effective Date are and will remain subject to the terms of the Pre-2005 EDCP.

All amounts earned and vested on and after the Effective Date are subject to the terms of the Plan. The Plan retains many of the attributes of the Pre-2005 EDCP, but is modified so as to achieve compliance with the requirements of the AJCA. The Board reserves the right to amend the Plan, either retroactively or prospectively, in whatever respect is required to achieve compliance with the requirements of the AJCA.

ADMINISTRATION OF THE PLAN AND DISCRETION

3.1.      The Committee, as Plan Administrator, shall have full power and authority to interpret the Plan, to prescribe, amend and rescind any rules, forms and procedures as it deems necessary or appropriate for the proper administration of the Plan and to make any other determinations and to take any other such actions as it deems necessary or advisable in carrying out its duties under the Plan. All action taken by the Plan Administrator arising out of, or in connection with, the administration of the Plan or any rules adopted thereunder, shall, in each case, lie within its sole discretion, and shall be final, conclusive and binding upon the Company, the Board, all Employees and Trustees, all Beneficiaries and all persons and entities having an interest therein.

Any action by the Committee assigning any of its responsibilities to specific persons who are all trustees, officers, or employees of the Company shall not constitute delegation of the Committee’s responsibility but rather shall be treated as the manner in which the Committee has determined internally to discharge such responsibility.

3.2.      The Plan Administrator shall serve without compensation for its services unless otherwise determined by the Board. All expenses of administering the Plan shall be paid by the Company.

3.3.      The Company shall indemnify and hold harmless the Plan Administrator from any and all claims, losses, damages, expenses (including counsel fees) and liability (including any amounts paid in settlement of any claim or any other matter with the consent of the Board) arising from any act or omission of such member, except when the same is due to gross negligence or willful misconduct.

3.4.      Any decisions, actions or interpretations to be made under the Plan by the Company, the Board or the Plan Administrator shall be made in its respective sole discretion, not as a fiduciary and need not be uniformly applied to similarly situated individuals and shall be final, binding and conclusive on all persons interested in the Plan.

ARTICLE 4

PARTICIPATION

4.1.      Election to Participate.

(a)      Timing of Election to Participate. Any Eligible Employee or Trustee may enroll in the Plan effective as of the first day of a Plan Year by filing a completed and fully executed Enrollment Agreement with the Plan Administrator by a date set by the Plan Administrator.

(i)      Base Salary/Board Remuneration. With respect to the deferral of Compensation that is classified by the Company as base salary or the deferral of Board Remuneration, an executed Enrollment Agreement must be filed by December 31 of the Plan Year preceding the Plan Year in which such base salary or Board Remuneration is to be earned, or such earlier time as may be established by the Plan Administrator.

(ii)      Bonus.

(A)      With respect to the deferral of Compensation that is classified by the Company as bonus, an executed Enrollment Agreement must be filed by December 31 of the Plan Year preceding the Plan Year in which such bonus is earned, or such earlier time as may be established by the Plan Administrator.

(B)      The Board may, as a condition of a bonus award, require that it be deferred under the Plan and may prescribe vesting and investment provisions with respect to such award, and may establish separate deadlines by which Enrollment Agreements may be filed with respect to such an award.

(iii)      Revocation of Election. Once each Plan Year, a Participant may cancel his deferral election with respect to all Compensation and Board Remuneration, other than Compensation that is classified by the Company as bonus, provided that such cancellation is communicated to the Company in writing and shall be effective for all base salary and Board Remuneration earned for the remainder of the Plan Year. Elections with respect to bonuses are irrevocable.

(b)      Amount of Deferral. Pursuant to said Enrollment Agreement, the Eligible Employee or Trustee shall irrevocably elect the percentages by which (as a result of payroll deduction) an amount equal to any whole percentage of the Participant’s Compensation or Board Remuneration will be deferred. Up to 85 percent (85%) of base salary, 100 percent (100%) of bonus and one hundred percent (100%) of Board Remuneration may be deferred; provided however, that deferrals will be made after required non-deferrable payroll tax deductions and any deductions elected by the Participant (including, but not limited to, deductions for payment of health insurance premiums). The Plan Administrator may establish minimum amounts that may be deferred under this Section 4.1 and may change such standards from time to time. Any such limit shall be communicated by the Plan Administrator to the Participants prior to the commencement of a Plan Year.

-9-

(c)      Accounts to Which Amounts Credited. Pursuant to said Enrollment Agreement, the Eligible Employee shall elect the Distribution Option Accounts to which such amounts will be credited, and shall provide such other information as the Plan Administrator shall require. Board Remuneration will only be credited to the Deferred Board Remuneration Account.

(d)      Form of Distribution from Accounts. The first Enrollment Agreement filed by an Eligible Employee during any Distribution Option Period must also set forth the Participant’s election as to the time and manner of distribution from the In-Service Distribution Account and of amounts credited for that Distribution Option Period. The first Enrollment Agreement filed by an Eligible Employee must set forth the time and manner of distribution with respect to amounts credited to the Retirement Distribution Account. The first Enrollment Agreement filed by a Trustee must set forth the manner of distribution with respect to amounts credited to the Deferred Board Remuneration Account.

4.2.      Special Rules for Filing of Elections.

(a)      New Hires. The Plan Administrator may, in its discretion, permit an Employee who first becomes an Eligible Employee after the beginning of a Plan Year due to such Employee’s commencement of Service, to enroll in the Plan for that Plan Year by filing a completed and fully executed Enrollment Agreement, in accordance with Section 4.1, as soon as practicable following the date the Employee becomes an Eligible Employee but, in any event, not later than 30 days after such date.

(b)      In its discretion, the Company may make Matching Contributions, which, if made, shall be credited to a Participant’s Retirement Distribution Account. equal to the matching contributions which would have been made on behalf of the Participant under the Brandywine Realty Trust 401(k) Profit Sharing Plan but for statutory limitations.

5.6.      Statement of Accounts. The Plan Administrator shall provide to each Participant, not less frequently than quarterly, a statement in such form as the Plan Administrator deems desirable for setting forth the balance standing to the credit of each Participant in each of his Distribution Option Accounts.

5.7.      Distributions from Accounts. Any distribution made to or on behalf of a Participant from one or more of his Distribution Option Accounts in an amount which is less than the entire balance of any such Account shall be made pro rata from each of the Earnings Crediting Options to which such Account is then allocated. For purposes of any provision of the Plan relating to distribution of benefits to Participants or Beneficiaries, the value of a Participant’s Distribution Option Accounts shall be determined as of a date as soon as reasonably practicable preceding the distribution date, as determined by the Plan Administrator in its sole discretion. In the case of any benefit payable in the form of a cash lump sum, the value of a Participant’s Distribution Option Accounts, as determined pursuant to this Section 5.7, shall be distributed. In the case of any benefit payable in the form of annual installments, as of any payment date, the amount of each installment payment shall be determined as the quotient of (a) the value of the Participant’s Distribution Option Account subject to distribution, as determined pursuant to this Section 5.7, divided by (b) the number of remaining annual installments immediately preceding the payment date.

ARTICLE 11

MISCELLANEOUS

11.1.      Amendment and Termination. The Plan may be amended, suspended, discontinued or terminated at any time by the Plan Administrator; provided, however, that no such amendment, suspension, discontinuance or termination shall reduce or in any manner adversely affect the rights of any Participant with respect to benefits that are payable or may become payable under the Plan based upon the balance of the Participant’s Accounts as of the effective date of such amendment, suspension, discontinuance or termination.

11.2.      Change of Control.

(a)      Notwithstanding Section 11.1, in the event of a Change of Control, Brandywine Realty Trust, or its successor, shall have the discretion, with respect to amounts standing to the credit of Participants’ Distribution Option Accounts, to modify and/or completely override Participants’ elections regarding the timing and/or form of distribution from such Distribution Option Accounts, including providing for a complete or partial distribution of all amounts due such Participants in the form of immediate lump sum payments. This Section 11.2(a) shall be applied consistent with and to the extent permitted by the AJCA.

(b)      In the event of a Change of Control in which Shares are converted into cash or equity, amounts deemed invested in the Employer Stock Fund as of such Change of Control shall be deemed to be converted in the same manner as Shares; provided if holders of Shares are given a choice between forms of consideration, the amounts deemed invested in the Employer Stock Fund as of such Change of Control shall be deemed converted into that form of consideration chosen by the majority of the holders of Shares.

11.3.      Claims Procedure.

(a)      Claim. A person who believes that he is being denied a benefit to which he is entitled under the Plan (hereinafter referred to as a “Claimant”) may file a written request for such benefit with the Plan Administrator, setting forth the claim.

(b)      Claim Decision. Upon receipt of a claim, the Plan Administrator shall advise the Claimant within ninety (90) days of receipt of the claim whether the claim is denied. If special circumstances require more than ninety (90) days for processing, the Claimant will be notified in writing within ninety (90) days of filing the claim that the Plan Administrator requires up to an additional ninety (90) days to reply. The notice will explain what special circumstances make an extension necessary and indicate the date a final decision is expected to be made.

If the Claimant does not receive a written denial notice or notice of an extension within ninety (90) days, the Claimant may consider the claim denied and may then request a review of denial of the claim, as described below.

If the claim is denied in whole or in part, the Claimant shall be provided a written opinion, using language calculated to be understood by the Claimant, setting forth:

-23-

(i)      The specific reason or reasons for such denial;

(ii)      The specific reference to pertinent provisions of this Plan on which such denial is based;

(iii)      A description of any additional material or information necessary for the Claimant to perfect his claim and an explanation why such material or such information is necessary;

(iv)      Appropriate information as to the steps to be taken if the Claimant wishes to submit the claim for review; and

(v)      The time limits for requesting a review under subsection (c) and for review under subsection (d) hereof.

(c)      Request for Review. Within sixty (60) days after the receipt by the Claimant of the written opinion described above, the Claimant may request in writing that the Plan Administrator review its determination. The Claimant or his duly authorized representative may, but need not, review the pertinent documents and submit issues and comments in writing for consideration by the Plan Administrator. If the Claimant does not request a review of the initial determination within such sixty (60) day period, the Claimant shall be barred and estopped from challenging the determination.

(d)      Review of Decision. Within sixty (60) days after the Plan Administrator’s receipt of a request for review, it will review the initial determination. After considering all materials presented by the Claimant, the Plan Administrator will render a written opinion, written in a manner calculated to be understood by the Claimant, setting forth the specific reasons for the decision and containing specific references to the pertinent provisions of this Agreement on which the decision is based. If special circumstances require that the sixty (60) day time period be extended, the Plan Administrator will so notify the Claimant and will render the decision as soon as possible, but no later than one hundred twenty (120) days after receipt of the request for review.

11.4.      Designation of Benefit. Each Participant may designate a Beneficiary or Beneficiaries (which Beneficiary may be an entity other than a natural person) to receive any payments which may be made following the Participant’s death. Such designation may be changed or canceled at any time without the consent of any such Beneficiary. Any such designation, change or cancellation must be made in a form approved by the Plan Administrator and shall not be effective until received by the Plan Administrator, or its designee. If no Beneficiary has been named, or the designated Beneficiary or Beneficiaries shall have predeceased the Participant, the Beneficiary shall be the Participant’s estate. If a Participant designates more than one Beneficiary, the interests of such Beneficiaries shall be paid in equal shares, unless the Participant has specifically designated otherwise.

11.5.      Limitation of Participant’s Right. Nothing in this Plan shall be construed as conferring upon any Participant any right to continue in Service or to continue to serve as a Trustee, nor shall it interfere with the rights of the Company to terminate the employment of any Participant and/or to take any personnel action affecting any Participant without regard to the effect which such action may have upon such Participant as a recipient or prospective recipient

-24-

of benefits under the Plan. Any amounts payable hereunder shall not be deemed salary or other compensation to a Participant for the purposes of computing benefits to which the Participant may be entitled under any other arrangement established by the Employer for the benefit of its employees.

11.6.      No Limitation on Company Actions. Nothing contained in the Plan shall be construed to prevent the Company from taking any action which is deemed by it to be appropriate or in its best interest. No Participant, Beneficiary, or other person shall have any claim against the Company as a result of such action.

11.7.      Obligations to Company. If a Participant becomes entitled to a distribution of benefits under the Plan, and if at such time the Participant has outstanding any debt, obligation, or other liability representing an amount owing to the Employer, then the Employer may offset such amount owed to it against the amount of benefits otherwise distributable. Such determination shall be made by the Plan Administrator.

11.8.      Nonalienation of Benefits. Except as expressly provided herein, no Participant or Beneficiary shall have the power or right to transfer (otherwise than by will or the laws of descent and distribution), alienate, or otherwise encumber the Participant’s or Beneficiary’s interest under the Plan. The Company’s obligations under this Plan are not assignable or transferable, except to (a) any corporation or partnership which acquires all or substantially all of the Company’s assets or (b) any corporation or partnership into which the Company may be merged or consolidated. A Participant’s or Beneficiary’s interest under the Plan is not assignable or transferable pursuant to a domestic relations order. The provisions of the Plan shall inure to the benefit of each Participant and the Participant’s Beneficiaries, heirs, executors, administrators or successors in interest.

11.9.      Protective Provisions. Each Participant shall cooperate with the Company by furnishing any and all information requested by the Company in order to facilitate the payment of benefits hereunder, taking such physical examinations as the Company may deem necessary and taking such other relevant action as may be requested by the Company. If a Participant refuses to cooperate, the Company shall have no further obligation to the Participant under the Plan, other than payment to such Participant of the then current balance of the Participant’s Distribution Option Accounts in accordance with his prior elections.

11.10.      Taxes. The Company may make such provisions and take such action as it may deem appropriate for the withholding of any taxes which the Company is required by any law or regulation of any governmental authority, whether Federal, state or local, to withhold in connection with any benefits under the Plan, including, but not limited to, the withholding of appropriate sums from any amount otherwise payable to the Participant (or his Beneficiary). Each Participant, however, shall be responsible for the payment of all individual tax liabilities relating to any such benefits.

11.11.      Unfunded Status of Plan. The Plan is an “unfunded” plan for tax and Employee Retirement Income Security Act purposes. This means that the value of a Participant’s Distribution Option Accounts is based on the value assigned to a hypothetical bookkeeping account, which is invested in hypothetical shares of investments funds available under the Plan. As the nature of the investment fund which forms the “index” or “meter” for the

valuation of the bookkeeping account changes, the valuation of the bookkeeping account changes as well. The amount owed to a Participant is based on the value assigned to the bookkeeping account. Brandywine Realty Trust may decide to use a “rabbi trust” to anticipate its potential Plan liabilities, and it may attempt to have Plan investments mirror the hypothetical investments deemed credited to the bookkeeping accounts. However, the liability to pay the benefits is Brandywine Realty Trusts’, and the assets of the rabbi trust are potentially available to satisfy the claims of non-participant creditors of Brandywine Realty Trust.

11.12.      Severability. If any provision of this Plan is held unenforceable, the remainder of the Plan shall continue in full force and effect without regard to such unenforceable provision and shall be applied as though the unenforceable provision were not contained in the Plan.

11.13.      Governing Law. The Plan shall be construed in accordance with and governed by the laws of the Commonwealth of Pennsylvania, without reference to the principles of conflict of laws.

11.14.      Headings. Headings are inserted in this Plan for convenience of reference only and are to be ignored in the construction of the provisions of the Plan.

11.15.      Gender, Singular and Plural. All pronouns and any variations thereof shall be deemed to refer to the masculine, feminine, or neuter, as the identity of the person or persons may require. As the context may require, the singular may read as the plural and the plural as the singular.

11.16.      Notice. Any notice or filing required or permitted to be given to the Plan Administrator under the Plan shall be sufficient if in writing and hand delivered, or sent by registered or certified mail, to Brandywine Realty Trust, 401 Plymouth Road, Suite 500, Plymouth Meeting, PA 19462, Attention: Chief Accounting Officer, or to such other entity as the Plan Administrator may designate from time to time. Such notice shall be deemed given as to the date of delivery, or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification.

Exhibit 14.1

BRANDYWINE REALTY TRUST
CODE OF BUSINESS CONDUCT AND ETHICS

Introduction

This Code of Business Conduct and Ethics covers a wide range of business practices and procedures. It does not cover every issue that may arise, but it sets out basic principles to guide employees, officers and trustees of the Company. All of our employees, officers and trustees must conduct themselves accordingly and seek to avoid even the appearance of improper behavior.

If a law conflicts with a policy in this Code, you must comply with the law; however, if a local custom or policy conflicts with this Code, you must comply with the Code. If you have any questions about these conflicts, you should ask your supervisor how to handle the situation.

Those who violate the standards in this Code will be subject to disciplinary action which may include immediate termination. If you are in a situation which you believe may violate or lead to a violation of this Code, follow the procedures described in Sections 14-16 of this Code.

1.     Compliance with Laws

Obeying the law, both in letter and in spirit, is the foundation on which this Company’s ethical standards are built. All employees, officers and trustees must obey the laws of the United States and the cities and states in which we operate. Although not all employees are expected to know the details of these laws, it is important to know enough to determine when to seek advice from supervisors.

2.     Ethical Conduct

Beyond compliance with laws, the Company requires that all its employees, officers, and trustees act in a manner which meets the highest standards of ethical behavior. The honesty and integrity of our business conduct must not be compromised. The Company will not condone ethical violations for the sake of personal gain, personal advantage, expediency, or perceived business advantage.

3.     Accounting and Auditing Matters

The Company’s requirement that employees, officers, and trustees follow the highest ethical standards applies directly to all actions which involve business accounting, financial reporting, internal accounting controls, auditing matters, and public disclosure obligations.

The Audit Committee of the Company has adopted special procedures for the receipt, retention, and treatment of complaints regarding accounting, internal accounting controls, or auditing matters. These procedures are set out in Sections 15 and 16 of this Code.

4.     Conflicts of Interest

A “conflict of interest” exists when a person’s private interest may or does interfere with the interests of the Company. A conflict can arise when an employee, officer or trustee takes actions or has interests that may make it difficult to perform his or her Company work objectively and effectively. Conflicts of interest may also arise when an employee, officer or trustee, or member of his or her family, receives improper personal benefits as a result of his or her position with the Company.

It is almost always a conflict of interest for a Company employee to work simultaneously for a competitor, customer or supplier. Employees are not allowed to work for a competitor as a consultant or board member. The best policy is to avoid any direct or indirect business connection with our competitors, customers or suppliers, except on our behalf. Conflicts of interest are prohibited as a matter of Company policy, except in circumstances approved by the Board of Trustees or the Audit Committee of the Board.

Conflicts of interest may not always be clear-cut, so if you have a question, you should consult with higher levels of management or the Company’s General Counsel. Any employee, officer or trustee who becomes aware of a conflict or potential conflict should bring it to the attention of a supervisor or follow the procedures described in Section 13 of this Code.

Employees, officers and trustees owe a duty to the Company to advance its legitimate interests when the opportunity to do so arises. In particular:

                      •      No payments, loans, employment or promises of employment, investment opportunities, vacation trips, gifts or entertainment (other than entertainment conforming to generally accepted business practices or gifts of nominal value not reasonably calculated to influence a decision) may be offered to or accepted by any employee, officer or trustee or a relative of such a person as a condition of the initial or continued engagement of a consultant, broker, vendor or third party working for the Company.

                     •      No payments (other than fees for services), loans, employment or promises of employment, investment opportunities, vacation trips, gifts or entertainment (other than entertainment conforming to generally accepted business practices or gifts of nominal value not reasonably calculated to influence a decision) may be offered to or accepted by any consultant, broker, vendor, government official or a relative of such third party in connection with any services being performed for the Company.

               •      No employee, officer or trustee may recommend any third party for work for the Company on a project or development of the Company where the third party's compensation is paid on the basis of any kickback or fee sharing arrangement with the employee, officer or trustee, nor may an employee, officer or trustee recommend any third party without full disclosure and written approval by the President and Chief Executive Officer or Senior Vice President, if such third party has any familial or pre-existing monetary relationship with the employee, officer or trustee or if such employee, officer or trustee has an equity or stock ownership position in such third party.

-2-

                    •      No employee shall use or appropriate materials, property, equipment, systems and procedures (if proprietary in nature) owned by the Company for his or her own personal financial gain except to the extent necessary for the performance of his or her duties for the Company.

In short, the purpose of business entertainment and gifts in a commercial setting is to create good will and sound working relationships, not to gain unfair advantage with customers. No gift or entertainment should be offered, given, provided or accepted by any Company employee, family member of an employee unless it: (1) is not a cash gift, (2) is consistent with customary business practices, (3) is not excessive in value, (4) cannot be construed as a bribe and is not reasonably calculated to influence a decision and (5) does not violate any laws or regulations. Please discuss with your supervisor any gifts or proposed gifts which you are not certain are appropriate.

                    •      No employee shall purchase or obtain any goods or services from any of the Company’s vendors or suppliers for personal use without the prior written approval of the President and Chief Executive Officer of the Company.

5.     Insider Trading

Employees, officers and trustees who have access to confidential information are not permitted to use or share that information for stock trading purposes or for any other purpose except the conduct of our business and in strict conformance with all applicable laws and SEC regulations. All non-public information about the Company should be considered confidential information. To use non-public information for personal financial benefit or to “tip” others who might make an investment decision on the basis of this information is not only unethical but also illegal. The Company’s policy on insider trading is set forth more fully in the “Policy Statement on Dealing with Company Information, Including Inside Information and Securities Insider Trading” furnished to all employees, officers and trustees. If you have any questions, please consult the Company’s General Counsel.

6.     Competition and Fair Dealing

We seek to outperform our competition fairly and honestly. We seek competitive advantages through superior performance, never through unethical or illegal business practices. Stealing proprietary information, possessing trade secret information that was obtained without the owner’s consent, or inducing such disclosures by past or present employees of other companies is prohibited. Each employee should endeavor to respect the rights of and deal fairly with the Company’s customers, suppliers, competitors and employees. No employee should take unfair advantage of anyone through manipulation, concealment, abuse of privileged information, misrepresentation of material facts, or any other intentional unfair-dealing practice.

7.     Discrimination, Harassment and Retaliation

The diversity of the Company’s employees is a tremendous asset. We are firmly committed to providing equal opportunity in all aspects of employment and will not tolerate discrimination, harassment or retaliation. The Company’s policy against discrimination applies

-3-

to any legally protected status including race, color, gender, religion, national origin, disability, veteran status, and age. This policy also prohibits discrimination against any person who provides information to a federal regulatory or law enforcement agency, a member of Congress or any committee of Congress, or to a supervisor concerning conduct which the employee reasonably believes constitutes a violation of securities laws or any provision of federal law relating to fraud against shareholders. The Company also prohibits discriminatory harassment of any employee covered by the policy against discrimination.

No employee, officer or trustee may retaliate against an individual for bringing a complaint of discrimination or for participating in an investigation or proceeding involving a complaint of discrimination.

No one may take any action harmful to any person for providing to a law enforcement officer any truthful information relating to the commission or possible commission of any federal offense.

8.     Health and Safety

The Company strives to provide each employee with a safe and healthful work environment. Each employee has responsibility for maintaining a safe and healthy workplace for all employees by following safety and health rules and practices and reporting accidents, injuries and unsafe conditions.

Violence and threatening behavior are not permitted. Employees should report to work in condition to perform their duties, free from the influence of illegal drugs or alcohol. The use of illegal drugs in the workplace will not be tolerated.

9.     Record-Keeping

The Company requires honest and accurate recording and reporting of information in order to make responsible business decisions. For example, only the true and actual number of hours worked should be reported.

Many employees regularly use business expense accounts, which must be documented and recorded accurately. If you are not sure whether a certain expense is legitimate, ask your supervisor or your controller.

All of the Company’s books, records, accounts and financial statements must be maintained in reasonable detail, must appropriately reflect the Company’s transactions and must conform both to applicable legal requirements and to the Company’s system of internal controls.

Business records and communications often become public, and we should avoid exaggeration, derogatory remarks, guesswork, or inappropriate characterizations of people and companies that can be misunderstood. This applies equally to e-mail, internal memos, and formal reports. Records should always be retained or destroyed according to the Company’s record retention policies. In accordance with those policies, in the event of litigation or governmental investigation please consult the Company’s General Counsel.

-4-

10.     Confidentiality

Employees must maintain the confidentiality of the information entrusted to them by the Company or its suppliers or customers, except when disclosure is authorized by the President and Chief Executive Officer, a Senior Vice President, the Company’s General Counsel, or required by law. Confidential information includes all non-public information that might be of use to competitors, or harmful to the Company or its suppliers or customers, if disclosed. It also includes information that suppliers and customers have entrusted to us. The obligation to preserve confidential information continues even after employment ends.

11.     Protection and Proper Use of Company Assets

All employees should endeavor to protect the Company’s assets and ensure their efficient use. Theft, carelessness and waste have a direct impact on the Company’s profitability. Any suspected incident of fraud or theft should be immediately reported for investigation.

The obligation of employees to protect the Company’s assets includes the Company’s proprietary information. Proprietary information includes business, marketing and service plans, records, salary information and any unpublished financial data and reports. Unauthorized use or distribution of this information would violate Company policy. It could also be illegal and result in civil or even criminal penalties.

12.     Payments to Government Personnel

The U.S. Foreign Corrupt Practices Act prohibits giving anything of value, directly or indirectly, to officials of foreign governments or foreign political candidates in order to obtain or retain business. It is strictly prohibited to make illegal payments to government officials of any country. In addition, the U.S. government has a number of laws and regulations regarding business gratuities which may be accepted by U.S. government personnel. The promise, offer or delivery to an official or employee of the U.S. government of a gift, favor or other gratuity in violation of these rules would not only violate Company policy but could also be a criminal offense. State and local governments, as well as foreign governments, may have similar rules. The Company’s General Counsel can provide guidance to you in this area.

13.     Waivers of the Code of Business Conduct and Ethics

Any waiver of this Code for executive officers or trustees may be made only by the Board or the Audit Committee and will be promptly disclosed as required by law or stock exchange regulation.

14.     Personal Responsibility

We must all work to ensure prompt and consistent action against violations of this Code. However, in some situations it is difficult to know right from wrong. Since we cannot anticipate every situation that will arise, it is important that we have a way to approach a new question or problem. These are the steps to keep in mind:

-5-

• Make sure you have all the facts. In order to reach the right solutions, we must be as fully informed as possible.

• Ask yourself: What specifically am I being asked to do? Does it seem unethical or improper? This will enable you to focus on the specific question you are faced with, and the alternatives you have. Use your judgment and common sense; if something seems unethical or improper, it probably is.

• Clarify your responsibility and role. In most situations, there is shared responsibility. Are your colleagues informed? It may help to get others involved and discuss the problem.

• Discuss the problem with your supervisor. This is the basic guidance for all situations. In many cases, your supervisor will be more knowledgeable about the question, and will appreciate being brought into the decision-making process. Remember that it is your supervisor’s responsibility to help solve problems.

• Seek help from Company resources. In the rare case where it may not be appropriate to discuss an issue with your supervisor, or where you do not feel comfortable approaching your supervisor with your question, discuss it locally with your office manager or with the Director of Human Resources. If that also is not appropriate, call our General Counsel.

• You may report ethical violations in confidence and without fear of retaliation. If your situation requires that your identity be kept secret, your anonymity will be protected. The Company does not permit retaliation of any kind against employees for good faith reports of ethical violations.

• Always ask first, act later: If you are unsure of what to do in any situation, seek guidance before you act.

15.     Reporting/Investigation Procedures

Any employee who reasonably believes that there has been a material violation of this Code of Conduct should report it immediately to the Company’s General Counsel. The General Counsel (or his/her designee) will promptly investigate the matter. The investigation will be handled discreetly and appropriately, and the information will be disclosed to others only on a need to know basis and as required by law. There will be no adverse action taken against employees who report violations of the Code of Conduct or who participate in the investigation. If the investigation leads to a conclusion that a material violation of the Code of Conduct has occurred, the Company will take appropriate corrective action which may include removal from a position as trustee or officer, and dismissal as an employee of the Company.

The Company recognizes the potentially serious impact of a false accusation. Employees are expected as part of the ethical standards required by this Code of Conduct to act responsibly in making complaints. Making a complaint without a good faith basis is itself an ethical violation. Any employee who makes a complaint in bad faith will be subject to appropriate corrective action including dismissal.

-6-

16.     Special Procedures for Reporting/Investigating Complaints Regarding Accounting, Internal Accounting Controls, and Auditing Matters

Any employee who reasonably believes that there has been a material violation of this Code of Conduct caused by questionable accounting or auditing matters has the right to submit a confidential, anonymous complaint to the Company General Counsel. The complaint should be made in written form and provide sufficient information so that a reasonable investigation can be conducted. The complaint should be addressed to the General Counsel of Brandywine Realty Trust.

We also offer a confidential Hotline available to all company employees and others to report suspected violations of this Code of Business Conduct and Ethics, including to a report a concern or complaint regarding the Company’s accounting, internal accounting controls or auditing matters to the confidential Hotline. These concerns and complaints will be referred to the Company’s Audit Committee or General Counsel.

The Hotline for callers from the U.S., Canada and Puerto Rico is:

1-877-888-0002 (toll-free)

Access to the Hotline, which is a service of an outside company, is available 24 hours a day, seven days a week. Calls to the Hotline are directed to a live, trained interviewer. Calls may be made anonymously.

Exhibit 99.1

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

The following discussion describes the material U.S. federal income tax consequences relating to the taxation of Brandywine Realty Trust as a REIT and the ownership and disposition of Brandywine’s common shares.

If Brandywine offers one or more series of preferred shares or debt securities under this prospectus, information about any income tax consequences to holders of those preferred shares or debt securities will be included in an applicable prospectus supplement.

Because this is a summary that is intended to address only material federal income tax consequences relating to the ownership and disposition of Brandywine’s common shares that will apply to all holders, this summary may not contain all the information that may be important to you. As you review this discussion, you should keep in mind that:

the tax consequences to you may vary depending on your particular tax situation;

special rules that are not discussed below may apply to you if, for example, you are a tax-exempt organization, a broker-dealer, a non-U.S. person, a trust, an estate, a regulated investment company, a financial institution, an insurance company, or otherwise subject to special tax treatment under the Code;

this summary does not address state, local or non-U.S. tax considerations (See “ – Other Tax Consequences”);

this summary deals only with our common shareholders that hold common shares as “capital assets” within the meaning of Section 1221 of the Code; and

this discussion is not intended to be, and should not be construed as, tax advice.

You are urged both to review the following discussion and to consult with your own tax advisor to determine the effect of ownership and disposition of our common shares on your individual tax situation, including any state, local or non-U.S. tax consequences.

As used herein, a “U.S. shareholder” means a beneficial owner of our common shares that is for U.S. federal income tax purposes (1) a citizen or resident of the U.S., (2) a corporation or partnership created or organized in or under the laws of the U.S. or any political subdivision thereof, (3) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (4) a trust if it (a) is subject to the primary supervision of a court within the U.S. and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

The information in this summary is based on the Code, current, temporary and proposed Treasury regulations, the legislative history of the Code, current administrative interpretations and practices of the Internal Revenue Service, including its practices and policies as endorsed in private letter rulings, which are not binding on the Internal Revenue Service, and existing court decisions. Future legislation, regulations, administrative interpretations and court decisions could change current law or adversely affect existing interpretations of current law. Any change could apply retroactively. We have not obtained any rulings from the Internal Revenue Service concerning the tax treatment of the matters discussed in this summary. Therefore, it is possible that the Internal Revenue Service could challenge the statements in this summary, which do not bind the Internal Revenue Service or the courts, and that a court could agree with the Internal Revenue Service.

On October 22, 2004, President Bush signed into law the American Jobs Creation Act of 2004 (the “Act”). The Act makes a number of changes to the REIT rules in the Code, generally taking effect in our taxable year beginning January 1, 2005. The following summary includes a discussion of the material changes made by the Act.

Taxation of Brandywine as a REIT

Brandywine first elected to be taxed as a REIT for the taxable year ended December 31, 1986, and has operated and expects to continue to operate in such a manner so as to remain qualified as a REIT for Federal income tax purposes. An entity that qualifies for taxation as a REIT and distributes to its shareholders an amount at least equal to 90% of its REIT taxable income (determined without regard to the deduction for dividends paid and by excluding any net capital gain) plus 90% of its income from foreclosure property (less the tax imposed on such income) is generally not subject to Federal corporate income taxes on net income that it currently distributes to shareholders. This treatment substantially eliminates the “double taxation” (at the corporate and shareholder levels) that generally results from investment in a corporation. However, we will be subject to Federal income tax as follows:

                         1.     We will be taxed at regular corporate rates on any undistributed REIT taxable income, including undistributed net capital gains.

                         2.     Under certain circumstances, we may be subject to the “alternative minimum tax” on our items of tax preference, if any.

                         3.     If we have net income from prohibited transactions (which are, in general, certain sales or other dispositions of property, other than foreclosure property, held primarily for sale to customers in the ordinary course of business) such income will be subject to a 100% tax. See “ – Sale of Partnership Property.”

                         4.     If we should fail to satisfy the 75% gross income test or the 95% gross income test (as discussed below), and nonetheless have maintained our qualification as a REIT because certain other requirements have been met, we will be subject to a 100% tax on the net income attributable to the greater of the amount by which we fail the 75% or 95% test, multiplied by a fraction intended to reflect our profitability.

                         5.     If we should fail to distribute during each calendar year at least the sum of (1) 85% of our REIT ordinary income for such year, (2) 95% of our REIT capital gain net income for such year, and (3) any undistributed taxable income from prior years, we would be subject to a 4% excise tax on the excess of such required distribution over the amounts actually distributed.

                         6.     If we have (1) net income from the sale or other disposition of “foreclosure property” (which is, in general, property acquired by us by foreclosure or otherwise or default on a loan secured by the property) which is held primarily for sale to customers in the ordinary course of business or (2) other nonqualifying income from foreclosure property, we will be subject to tax on such income at the highest corporate rate.

                         7.     If we were to acquire any asset from a taxable “C” corporation in a carry-over basis transaction, we could be liable for specified tax liability inherited from that “C” corporation with respect to that corporation's “built-in gain” in its assets. Built-in gain is the amount by which an asset's fair market value exceeds its adjusted tax basis. We would not be subject to tax on the built in gain, however, if we do not dispose of the acquired property within the 10-year period following acquisition of such property.

Qualification of Brandywine as a REIT

The Code defines a REIT as a corporation, trust or association:

                         1.     that is managed by one or more trustees or directors;

                         2.     the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest;

                         3.     that would be taxable as a domestic corporation but for Sections 856 through 859 of the Code;

                         4.     that is neither a financial institution nor an insurance company subject to certain provisions of the Code;

                         5.     the beneficial ownership of which is held by 100 or more persons;

                         6.     during the last half of each taxable year not more than 50% in value of the outstanding shares of which is owned, directly or indirectly, by five or fewer individuals (as defined in the Code to include specified entities);

                         7.     that makes an election to be taxable as a REIT, or has made this election for a previous taxable year which has not been revoked or terminated, and satisfies all relevant filing and other administrative requirements established by the Internal Revenue Service that must be met to elect and maintain REIT status;

                         8.     that uses a calendar year for federal income tax purposes and complies with the record keeping requirements of the Code and the Treasury Regulations; and

                         9.     that meets other applicable tests, described below, regarding the nature of its income and assets and the amount of its distributions.

Conditions (1) through (4) must be satisfied during the entire taxable year, and condition (5) must be satisfied during at least 335 days of a taxable year of 12 months, or during a proportionate part of a taxable year of less than 12 months. We have previously issued Common Shares in sufficient proportions to allow us to satisfy requirements (5) and (6) (the “100 Shareholder” and “five-or-fewer” requirements). In addition, our Declaration of Trust provides restrictions regarding the transfer of our shares that are intended to assist us in continuing to satisfy the requirements described in conditions (5) and (6) above. See “ – Description of Shares of Beneficial Interest – Restrictions on Transfer.” However, these restrictions may not ensure that we will, in all cases, be able to satisfy the requirements described in conditions (5) and (6) above. In addition, we have not obtained a ruling from the Internal Revenue Service as to whether the provisions of our Declaration of Trust concerning restrictions on transfer and conversion of Common Shares to “Excess Shares” will allow us to satisfy conditions (5) and (6). If we fail to satisfy such share ownership requirements, our status as a REIT will terminate. However, for taxable years beginning on or after January 1, 2005, the Act provides that if the failure to meet the share ownership requirements is due to reasonable cause and not due to willful neglect, we may avoid termination of our REIT status by paying a penalty of $50,000.

To monitor compliance with condition (6) above, a REIT is required to send annual letters to its shareholders requesting information regarding the actual ownership of its shares. If we comply with the annual letters requirement and do not know or, exercising reasonable diligence, would not have known of our failure to meet condition (6) above, then we will be treated as having met condition (6) above.

Qualified REIT Subsidiaries

We currently have several wholly-owned subsidiaries which are “qualified REIT subsidiaries” and we may have additional wholly-owned “qualified REIT subsidiaries” in the future. The Code provides that a corporation that is a “qualified REIT subsidiary” shall not be treated as a separate corporation, and all assets, liabilities and items of income, deduction and credit of a “qualified REIT subsidiary” shall be treated as assets, liabilities and items of income, deduction and credit of the REIT. A “qualified REIT subsidiary” is a corporation, other than a taxable REIT subsidiary (discussed below), all of the capital stock of which is owned by the REIT and that has not elected to be a “Taxable REIT Subsidiary.” In applying the requirements described herein, all of our “qualified REIT subsidiaries” will be ignored, and all assets, liabilities and items of income, deduction and credit of such subsidiaries will be treated as our assets, liabilities and items of income, deduction and credit. These subsidiaries, therefore, will not be subject to federal corporate income taxation, although they may be subject to state and local taxation.

Taxable REIT Subsidiaries

We currently have several “taxable REIT subsidiaries,” and may have additional taxable REIT subsidiaries in the future. A REIT may hold any direct or indirect interest in a corporation that qualifies as a “taxable REIT subsidiary” as long as the value of the REIT's holdings of taxable REIT subsidiary securities do not exceed 20% of the value of the REIT's total assets. To qualify as a taxable REIT subsidiary, the subsidiary and the REIT must make a joint election to treat the subsidiary as a taxable REIT subsidiary. A taxable REIT subsidiary also includes any corporation (other than a REIT or a qualified REIT subsidiary) in which a taxable REIT subsidiary directly or indirectly owns more than 35% of the total voting power or value. See “ – Asset Tests” below. A taxable REIT subsidiary will pay tax at regular corporate income rates on any taxable income it earns.

A taxable REIT subsidiary can perform tenant services without causing the REIT to receive impermissible tenant services income under the REIT income tests. However, several provisions regarding the arrangements between a REIT and its taxable REIT subsidiaries ensure that a taxable REIT subsidiary will be subject to an appropriate level of federal income taxation. For example, a taxable REIT subsidiary is limited in its ability to deduct interest payments made to a REIT. In addition, a REIT will be obligated to pay a 100% penalty tax on some payments that it receives or on certain expenses deducted by the taxable REIT subsidiary if the economic arrangements between the REIT, the REIT's tenants and the taxable REIT subsidiary are not comparable to similar arrangements among unrelated parties.

Ownership of Partnership Interests by a REIT

A REIT that is a partner in a partnership is deemed to own its proportionate share of the assets of the partnership and is deemed to receive the income of the partnership attributable to such share. In addition, the character of the assets and gross income of the partnership retains the same character in the hands of the REIT. Accordingly, our proportionate share of the assets, liabilities and items of income of the Operating Partnership are treated as assets, liabilities and items of income of ours for purposes of applying the requirements described herein. Brandywine has control over the Operating Partnership and most of the partnership and limited liability company subsidiaries of the Operating Partnership and intends to operate them in a manner that is consistent with the requirements for qualification of Brandywine as a REIT.

Income Tests

In order to qualify as a REIT, Brandywine must generally satisfy two gross income requirements on an annual basis. First, at least 75% of our gross income (excluding gross income from prohibited transactions) for each taxable year must be derived directly or indirectly from investments relating to real property or mortgages on real property (including “rents from real property” and, in certain circumstances, interest) or from certain types of temporary investments. Second, at least 95% of our gross income (excluding gross income from prohibited transactions) for each taxable year must be derived from the same items which qualify under the 75% gross income test, and from dividends, interest and gain from the sale or disposition of securities.

Rents received by a REIT will qualify as “rents from real property” in satisfying the gross income requirements described above only if several conditions are met. First, the amount of rent must not be based in whole or in part on the income or profits of any person. However, an amount received or accrued generally will not be excluded from the term “rents from real property” solely by reason of being based on a fixed percentage or percentages of gross receipts or sales. Second, subject to certain limited exceptions, rents received from a tenant will not qualify as “rents from real property” in satisfying the gross income tests if the REIT, or a direct or indirect

owner of 10% or more of the REIT, directly or constructively, owns 10% or more of such tenant (a “Related Party Tenant”). Third, if rent attributable to personal property, leased in connection with a lease of real property, is greater than 15% of the total rent received under the lease, then the portion of rent attributable to such personal property will not qualify as “rents from real property.” Finally, in order for rents received with respect to a property to qualify as “rents from real property,” the REIT generally must not operate or manage the property or furnish or render services to tenants, except through an “independent contractor” who is adequately compensated and from whom the REIT derives no income, or through a taxable REIT subsidiary. The “independent contractor” requirement, however, does not apply to the extent the services provided by the REIT are “usually or customarily rendered” in connection with the rental of space for occupancy only, and are not otherwise considered “rendered to the occupant.” In addition, a de minimis rule applies with respect to non-customary services. Specifically, if the value of the non-customary service income with respect to a property (valued at no less than 150% of the direct costs of performing such services) is 1% or less of the total income derived from the property, then all rental income except the non-customary service income will qualify as “rents from real property.” A taxable REIT subsidiary may provide services (including noncustomary services) to a REIT's tenants without “tainting” any of the rental income received by the REIT, and will be able to manage or operate properties for third parties and generally engage in other activities unrelated to real estate.

We do not anticipate receiving rent that is based in whole or in part on the income or profits of any person (except by reason of being based on a fixed percentage or percentages of gross receipts or sales consistent with the rules described above). We also do not anticipate receiving more than a de minimis amount of rents from any related party tenant or rents attributable to personal property leased in connection with real property that will exceed 15% of the total rents received with respect to such real property.

We provide services to our properties that we own through the Operating Partnership, and we believe that all of such services will be considered “usually or customarily rendered” in connection with the rental of space for occupancy only so that the provision of such services will not jeopardize the qualification of rent from the properties as “rents from real property.” In the case of any services that are not “usual and customary” under the foregoing rules, we will employ an “independent contractor” or a taxable REIT subsidiary to provide such services.

The Operating Partnership may receive certain types of income that will not qualify under the 75% or 95% gross income tests. In particular, dividends received from a taxable REIT subsidiary will not qualify under the 75% test. We believe, however, that the aggregate amount of such items and other non-qualifying income in any taxable year will not cause Brandywine to exceed the limits on non-qualifying income under either the 75% or 95% gross income tests.

If Brandywine fails to satisfy one or both of the 75% of 95% gross income tests for any taxable year, Brandywine may nevertheless qualify as a REIT for such year if it is entitled to relief under certain provisions of the Code. These relief provisions will be generally available if (1) the failure to meet such tests was due to reasonable cause and not due to willful neglect, (2) we have attached a schedule of the sources of our income to our return, and (3) any incorrect information on the schedule was not due to fraud with intent to evade tax. In addition, for taxable years beginning on or after January 1, 2005, the Act provides that we must also file a disclosure schedule with the IRS after we determine that we have not satisfied one of the gross income tests. It is not possible, however, to state whether in all circumstances Brandywine would be entitled to the benefit of these relief provisions. As discussed above in “Taxation of Brandywine as a REIT,” even if these relief provisions apply, a tax would be imposed based on the excess net income.

Any gain realized by us on the sale of any property held as inventory or other property held primarily for sale to customers in the ordinary course of business, including Brandywine’s share of this type of gain realized by the Operating Partnership, will be treated as income from a prohibited transaction that is subject to a 100% penalty tax. Under existing law, whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends on all the facts and circumstances of a particular transaction. We intend to hold properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing, owning and operating properties, and to make occasional sales of properties as are consistent with our investment objectives. We cannot provide any assurance, however, that the Internal Revenue Service might not contend that one or more of these sales are subject to the 100% penalty tax.

Asset Tests

At the close of each quarter of each taxable year, Brandywine must satisfy the following tests relating to the nature of our assets:

First, at least 75% of the value of our total assets must be represented by cash or cash items (which generally include receivables), government securities, “real estate assets” (which generally include interests in real property, interests in mortgages on real property and shares of other REITs), or, in cases where we receive proceeds from shares of beneficial interest or publicly offered long-term (at least five-year) debt, temporary investments in stock or debt instruments during the one-year period following our receipt of such proceeds.

Second, of the investments not included in the 75% asset class, the value of any one issuer's securities we own may not exceed 5% of the value of our total assets (“5% test”); and we may not own more than 10% of the vote or value of any one issuer's outstanding securities (“10% test”), except for our interests in the Operating Partnership, noncorporate subsidiaries, taxable REIT subsidiaries and any qualified REIT subsidiaries, and except (with respect to the 10% value test) certain “straight debt” securities.

Effective for taxable years beginning after December 31, 2000, the Act expands the safe harbor under which certain types of securities are disregarded for purposes of the 10% value limitation to include (i) straight debt securities (including straight debt securities that provides for certain contingent payments); (ii) any loan to an individual or an estate; (iii) any rental agreement described in Section 467 of the Code, other than with a “related person”; (iv) any obligation to pay rents from real property; (v) certain securities issued by a State or any political subdivision thereof, or the Commonwealth of Puerto Rico; (vi) any security issued by a REIT; and (vii) any other arrangement that, as determined by the Secretary of the Treasury, is excepted from the definition of a security. In addition, for purposes of applying the 10% value limitation, (a) a REIT’s interest as a partner in a partnership is not considered a security; (b) any debt instrument issued by a partnership is not treated as a security if at least 75% of the partnership’s gross income is from sources that would qualify for the 75% REIT gross income test, and (c) any debt instrument issued by a partnership is not treated as a security to the extent of the REIT’s interest as a partner in the partnership.

Third, not more than 20% of the value of our assets may be represented by securities of one or more taxable REIT subsidiaries.

For purposes of the 75% asset test, the term “interest in real property” includes an interest in land and improvements thereon, such as buildings or other inherently permanent structures, including items that are structural components of such buildings or structures, a leasehold of real property, and an option to acquire real property, or a leasehold of real property.

For purposes of the asset tests, we are deemed to own our proportionate share of the assets of the Operating Partnership, any qualified REIT subsidiary, and each noncorporate subsidiary, rather than our interests in those entities. At least 75% of the value of our total assets have been and will be represented by real estate assets, cash and cash items, including receivables and government securities. In addition, except for our interests in the Operating Partnership, the noncorporate subsidiaries, another REIT, any taxable REIT subsidiary and any qualified REIT subsidiary, we have not owned, and will not own (1) securities of any one issuer the value of which exceeds 5% of the value of our total assets, or (2) more than 10% of the vote or value of any one issuer's outstanding securities. We have not owned, and will not own, securities of taxable REIT subsidiaries with an aggregate value in excess of 20% of the value of our assets.

As noted above, one of the requirements for qualification as a REIT is that a REIT not own more than 10% of the vote or value of any corporation other than the stock of a qualified REIT subsidiary (of which the REIT is required to own all of such stock), a taxable REIT subsidiary and stock in another REIT. The Operating Partnership owns all or substantially all of the voting securities of several entities that have elected to be taxed as corporations and are taxable REIT subsidiaries. We and each taxable REIT subsidiary have jointly made a taxable REIT subsidiary election and, therefore, ownership of such subsidiaries will not violate the 10% test.

We own 100% of the common shares of Atlantic American Properties Trust, a Maryland business trust that has elected to be treated as a real estate investment trust (“AAPT”). Provided that AAPT continues to qualify as a REIT (including satisfaction of the ownership, income, asset and distribution tests discussed herein) the common shares of AAPT will qualify as real estate assets under the 75% test. However, if AAPT fails to qualify as a REIT in any year, then the common shares of AAPT will not qualify as real estate assets under the 75% test. In addition, because we own more than 10% of the common shares of AAPT, Brandywine would not satisfy the 10% test if AAPT were to fail to qualify as a REIT. Accordingly, Brandywine’s qualification as a REIT depends upon the ability of AAPT to continue to qualify as a REIT.

After initially meeting the asset tests at the close of any quarter, Brandywine will not lose its status as a REIT for failure to satisfy the asset tests at the end of a later quarter solely by reason of changes in asset values. If the failure to satisfy the asset tests results from an acquisition of securities or other property during a quarter, the failure can be cured by disposition of sufficient nonqualifying assets within 30 days after the close of that quarter. We intend to maintain adequate records of the value of our assets to ensure compliance with the asset tests, and to take such other action within 30 days after the close of any quarter as may be required to cure any noncompliance. However, there can be no assurance that such other action will always be successful. If we fail to cure any noncompliance with the asset tests within such time period, our status as a REIT would be lost.

For taxable years beginning on or after January 1, 2005, the Act provides relief from certain failures to satisfy the REIT asset tests. If the failure relates to the 5% test or 10% test, and if the failure is de minimis (does not exceed the lesser of $10 million or 1% of our assets as of the end of the quarter), we may avoid the loss of our REIT status by disposing of sufficient assets to cure the failure within 6 months after the end of the quarter in which the failure was identified. For failures to meet the asset tests that are more than a de minimis amount, we may avoid the loss of our REIT status if: the failure was due to reasonable cause, we file a disclosure schedule at the end of the quarter in which the failure was identified, we dispose of sufficient assets to cure the failure within 6 months after the end of the quarter, and we pay a tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated by the non-qualifying assets.

Annual Distribution Requirements

In order to qualify as a REIT, Brandywine is required to distribute dividends (other than capital gain dividends) to our shareholders in an amount at least equal to (1) the sum of (a) 90% of its “REIT taxable income” (computed without regard to the dividends paid deduction and the REIT's net capital gain) and (b) 90% of the net income (after tax), if any, from foreclosure property, minus (2) certain “excess” non-cash income. In addition, if we dispose of a built-in gain asset during the 10 year period following its acquisition, we will be required to distribute at least 90% of the built-in gain (after tax), if any, recognized on the disposition of such asset. Such distributions must be paid in the taxable year to which they relate, or in the following taxable year if declared before Brandywine timely files its tax return for such year and if paid on or before the first regular dividend payment after such declaration. To the extent that we do not distribute all of our net capital gain or we distribute at least 95%, but less than 100%, of our “REIT taxable income,” as adjusted, we will be subject to tax on the undistributed amount at regular corporate tax rates. Furthermore, if we should fail to distribute during each calendar year at least the sum of (1) 85% of our REIT ordinary income for such year, (2) 95% of our REIT net capital gain income for such year and (3) any undistributed taxable income from prior periods, we would be subject to a 4% excise tax on the excess of such required distribution over the amounts actually distributed.

Brandywine intends to make timely distributions sufficient to satisfy the annual distribution requirements. In this regard, the limited partnership agreement of the Operating Partnership authorizes Brandywine, as general partner, to operate the partnership in a manner that will enable it to satisfy the REIT requirements and avoid the imposition of any federal income or excise tax liability. It is possible that we, from time to time, may not have sufficient cash or other liquid assets to meet the 90% distribution requirement due primarily to the expenditure of cash for nondeductible items such as principal amortization or capital expenditures. In order to meet the 90% distribution requirement, we may borrow or may cause the Operating Partnership to arrange for short-term or other borrowing to permit the payment of required distributions or declare a consent dividend, which is a hypothetical distribution to shareholders out of our earnings and profits. The effect of such a consent dividend (which, in conjunction with distributions actually paid, must not be preferential to those shareholders who agree to such treatment) would be that such shareholders would be treated for federal income tax purposes as if they had received such amount in cash, and they then had immediately contributed such amount back to Brandywine as additional paid-in capital. This would result in taxable income to those shareholders without the receipt of any actual cash distribution but would also increase their tax basis in their shares by the amount of the taxable income recognized.

Under certain circumstances, Brandywine may be able to rectify a failure to meet the distribution requirement for a given year by paying “deficiency dividends” to shareholders in a later year that may be included in Brandywine’s deduction for distributions paid for the earlier year. Thus, Brandywine may be able to avoid being taxed on amounts distributed as deficiency dividends; however, Brandywine will be required to pay to the Internal Revenue Service interest based upon the amount of any deduction taken for deficiency dividends.

Failure to Qualify

For taxable years beginning on or after January 1, 2005, the Act provides relief for many failures to satisfy the REIT requirements. In addition to the relief provisions for failures to satisfy the income and asset tests (discussed above), the Act provides additional relief for other failures to satisfy REIT requirements. If the failure is due to reasonable cause and not due to willful neglect, and we elect to pay a penalty of $50,000 for each failure, we can avoid the loss of our REIT status.

If Brandywine fails to qualify for taxation as a REIT in any taxable year and the relief provisions do not apply, it will be subject to tax (including any applicable corporate alternative minimum tax) on its taxable income at regular corporate rates. Distributions to shareholders in any year in which Brandywine fails to qualify will not be deductible to us. In such event, to the extent of Brandywine’s current and accumulated earnings and profits, all distributions to shareholders will be taxable to them as ordinary income, and, subject to certain limitations of the Code, corporate distributees may be eligible for the dividends received deduction. Unless entitled to relief under specific statutory provisions, Brandywine also will be disqualified from taxation as a REIT for the four taxable years following the year during which qualification was lost. It is not possible to state whether in all circumstances Brandywine would be entitled to such statutory relief.

Income Taxation of the Operating Partnership, Subsidiary Partnerships and Their Partners

The following discussion summarizes certain Federal income tax considerations applicable to Brandywine’s investment in the Operating Partnership and the Operating Partnership's subsidiary partnerships and limited liability companies (referred to as the “Subsidiary Partnerships”).

Classification of the Operating Partnership and Subsidiary Partnerships as Partnerships

Brandywine owns all of its Properties or the economic interests therein through the Operating Partnership. Brandywine will be entitled to include in its income its distributive share of the income and to deduct its distributive share of the losses of the Operating Partnership (including the Operating Partnership's share of the income or losses of the Subsidiary Partnerships) only if the Operating Partnership and the Subsidiary Partnerships (collectively, the “Partnerships”) are classified for Federal income tax purposes as partnerships rather than as associations taxable as corporations. For taxable periods prior to January 1, 1997, an organization formed as a partnership was treated as a partnership for Federal income tax purposes rather than as a corporation only if it had no more than two of the four corporate characteristics that the Treasury Regulations used to distinguish a partnership from a corporation for tax purposes. These four characteristics were continuity of life, centralization of management, limited liability and free transferability of interests.

Neither the Operating Partnership nor any of the Subsidiary Partnerships requested a ruling from the Internal Revenue Service that it would be treated as a partnership for Federal income tax purposes.

Effective January 1, 1997, Treasury Regulations eliminated the four-factor test described above and, instead, permit partnerships and other non-corporate entities to be taxed as partnerships for federal income tax purposes without regard to the number of corporate characteristics possessed by such entity. Under those Treasury Regulations, both the Operating Partnership and each of the Subsidiary Partnerships will be classified as partnerships for federal income tax purposes except for any entity for which an affirmative election is made by the

entity to be taxed as a corporation. Under a special transitional rule in the Treasury Regulations, the Internal Revenue Service will not challenge the classification of an existing entity such as the Operating Partnership or a Subsidiary Partnership for periods prior to January 1, 1997 if: (1) the entity has a “reasonable basis” for its classification; (2) the entity and each of its members recognized the federal income tax consequences of any change in classification of the entity made within the 60 months prior to January 1, 1997; and (3) neither the entity nor any of its members had been notified in writing on or before May 8, 1996 that its classification was under examination by the Internal Revenue Service. Neither the Operating Partnership nor any of the Subsidiary Partnerships changed its classification within the 60 month period preceding May 8, 1996, nor was any one of them notified that its classification as a partnership for federal income tax purposes was under examination by the Internal Revenue Service.

If for any reason the Operating Partnership or a Subsidiary Partnership were classified as an association taxable as a corporation rather than as a partnership for Federal income tax purposes, Brandywine would not be able to satisfy the income and asset requirements for REIT status. See “ – Income Tests” and “ – Asset Tests.” In addition, any change in any such Partnership's status for tax purposes might be treated as a taxable event, in which case we might incur a tax liability without any related cash distribution. See “ – Annual Distribution Requirements.” Further, items of income and deduction of any such Partnership would not pass through to its partner (e.g., Brandywine), and its partners would be treated as shareholders for tax purposes. Any such Partnership would be required to pay income tax at corporate tax rates on its net income and distributions to its partners would constitute dividends that would not be deductible in computing such Partnership's taxable income.

Partnership Allocations

Although a partnership agreement will generally determine the allocation of income and losses among partners, such allocations will be disregarded for tax purposes if they do not comply with the provisions of Section 704(b) of the Code and the Treasury Regulations promulgated thereunder, which require that partnership allocations respect the economic arrangement of the partners.

If an allocation is not recognized for Federal income tax purposes, the item subject to the allocation will be reallocated in accordance with the partners' interests in the partnership, which will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the partners with respect to such item. The Operating Partnership's allocations of taxable income and loss are intended to comply with the requirements of Section 704(b) of the Code and the Treasury Regulations promulgated thereunder.

Tax Allocations With Respect to Contributed Properties

We believe that the fair market values of the properties contributed directly or indirectly to the Operating Partnership in various transactions were different than the tax basis of such Properties. Pursuant to Section 704(c) of the Code, items of income, gain, loss and deduction attributable to appreciated or depreciated property that is contributed to a partnership in exchange for an interest in the partnership must be allocated for Federal income tax purposes in a manner such that the contributor is charged with or benefits from the unrealized gain or unrealized loss associated with the property at the time of the contribution. The amount of such unrealized gain or unrealized loss is generally equal to the difference between the fair market value of the contributed property at the time of contribution and the adjusted tax basis of such property at the time of contribution (the “Pre-Contribution Gain or Loss”). The partnership agreement of the Operating Partnership requires allocations of income, gain, loss and deduction attributable to such contributed property to be made in a manner that is consistent with Section 704(c) of the Code. Thus, if the Operating Partnership sells contributed property at a gain or loss, such gain or loss will be allocated to the contributing partners, and away from us, generally to the extent of the Pre-Contribution Gain or Loss.

The Treasury Department has issued final regulations under Section 704(c) of the Code which give partnerships flexibility in ensuring that a partner contributing property to a partnership receives the tax benefits and burdens of any Pre-Contribution Gain or Loss attributable to the contributed property. These regulations permit partnerships to use any “reasonable method” of accounting for Pre-Contribution Gain or Loss. These regulations specifically describe three reasonable methods, including (1) the “traditional method” under current law, (2) the traditional method with the use of “curative allocations” which would permit distortions caused by Pre-Contribution Gain or Loss to be rectified on an annual basis and (3) the “remedial allocation method” which is similar to the traditional method with “curative allocations.” The partnership agreement of the Operating Partnership permits us, as general partner, to select one of these methods to account for Pre-Contribution Gain or Loss.

Depreciation

The Operating Partnership's assets other than cash consist largely of appreciated property contributed by its partners. Assets contributed to a partnership in a tax-free transaction generally retain the same depreciation method and recovery period as they had in the hands of the partner who contributed them to the partnership. Accordingly, the Operating Partnership's depreciation deductions for its real property are based largely on the historic tax depreciation schedules for the properties prior to their contribution to the Operating Partnership. The properties are being depreciated over a range of 15 to 40 years using various methods of depreciation which were determined at the time that each item of depreciable property was placed in service. Any depreciable real property purchased by the Partnerships is currently depreciated over 40 years. In certain instances where a partnership interest rather than real property is contributed to the Partnership, the real property may not carry over its recovery period but rather may, similarly, be subject to the lengthier recovery period.

Section 704(c) of the Code requires that depreciation as well as gain and loss be allocated in a manner so as to take into account the variation between the fair market value and tax basis of the property contributed. Thus, because most of the property contributed to the Operating Partnerships is appreciated, we will generally receive allocations of tax depreciation in excess of our percentage interest in the Operating Partnership. Depreciation with respect to any property purchased by the Operating Partnership subsequent to the admission of its partners, however, will be allocated among the partners in accordance with their respective percentage interests in the Operating Partnership.

As described previously, Brandywine, as a general partner of the Operating Partnership, may select any permissible method to account for Pre-Contribution Gain or Loss. The use of certain of these methods may result in us being allocated lower depreciation deductions than if a different method were used. The resulting higher taxable income and earnings and profits, as determined for federal income tax purposes, should decrease the portion of distributions which may be treated as a return of capital. See “– Taxation of Taxable Domestic Shareholders.”

Basis in Operating Partnership Interest

Our adjusted tax basis in each of the partnerships in which we have an interest generally (1) will be equal to the amount of cash and the basis of any other property contributed to such partnership by us, (2) will be increased by (a) our allocable share of such partnership's income and (b) our allocable share of any indebtedness of such partnership, and (3) will be reduced, but not below zero, by our allocable share of (a) such partnership's loss and (b) the amount of cash and the tax basis of any property distributed to us and by constructive distributions resulting from a reduction in our share of indebtedness of such partnership.

If our allocable share of the loss (or portion thereof) of any partnership in which we have an interest would reduce the adjusted tax basis of our partnership interest in such partnership below zero, the recognition of such loss will be deferred until such time as the recognition of such loss (or portion thereof) would not reduce our adjusted tax basis below zero. To the extent that distributions to us from a partnership, or any decrease in our share of the nonrecourse indebtedness of a partnership (each such decrease being considered a constructive cash distribution to the partners), would reduce our adjusted tax basis below zero, such distributions (including such constructive distributions) would constitute taxable income to us. Such distributions and constructive distributions normally would be characterized as long-term capital gain if our interest in such partnership has been held for longer than the long-term capital gain holding period (currently 12 months).

Sale of Partnership Property

Generally, any gain realized by a partnership on the sale of property held by the partnership for more than 12 months will be long-term capital gain, except for any portion of such gain that is treated as depreciation or cost recovery recapture. However, under requirements applicable to REITs under the Code, our share as a partner of any gain realized by the Operating Partnership on the sale of any property held as inventory or other property held

primarily for sale to customers in the ordinary course of a trade or business will be treated as income from a prohibited transaction that is subject to a 100% penalty tax. See “– Taxation of Brandywine as a REIT.” Such prohibited transaction income will also have an adverse effect upon our ability to satisfy the income tests for REIT status. See “ – Income Tests.” Whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends on all the facts and circumstances with respect to the particular transaction. A safe harbor to avoid classification as a prohibited transaction exists as to real estate assets held for the production of rental income by a REIT if the following requirements are satisfied: (1) the REIT has held the property for at least four years, (2) aggregate expenditures of the REIT during the four-year period preceding the sale which are includible in basis do not exceed 30% of the net selling price of the property, (3) (a) during the taxable year the REIT has made no more than seven sales of property or, in the alternative, (b) the aggregate of the adjusted bases of all properties sold during the year does not exceed 10% of the adjusted bases of all of the REIT's properties during the year, (4) in the case of property, not acquired through foreclosure or lease termination, the REIT has held the property for not less than four years for the production of rental income, and (5) if the requirement of clause (3) (a) is not satisfied, substantially all of the marketing and development expenditures were made through an independent contractor. Brandywine, as general partner of the Operating Partnership, believes that the Operating Partnership intends to hold its properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing, owning, operating and leasing properties and to make such occasional sales of the properties as are consistent with its and the Operating Partnership's investment objectives. No assurance can be given, however, that every property sale by the Partnerships will constitute a sale of property held for investment.

Taxation of Taxable U.S. Shareholders

As long as Brandywine qualifies as a REIT, distributions made to Brandywine’s taxable U.S. shareholders out of current or accumulated earnings and profits (and not designated as capital gain dividends or qualified dividend income) will be dividends taxable to such U.S. shareholders as ordinary income and will not be eligible for the dividends received deduction for corporations. Distributions that are designated as long-term capital gain dividends will be taxed as long-term capital gains (to the extent they do not exceed our actual net capital gain for the taxable year) without regard to the period for which the U.S. shareholder has held its shares of beneficial interest. However, corporate shareholders may be required to treat up to 20% of certain capital gain dividends as ordinary income. For calendar years 2003 through 2008, distributions that are designated as qualified dividend income will be taxed at the same rate as long-term capital gains. We may designate a distribution as qualified dividend income to the extent of (1) qualified dividend income we receive during the current year (for example, dividends received from a taxable REIT subsidiary), and (2) income on which we have been subject to corporate level tax during the prior year (for example, undistributed REIT taxable income) less the tax paid on that income. We expect that ordinary dividends paid by Brandywine generally will not be eligible for treatment as qualified dividend income to any significant extent. Distributions in excess of current and accumulated earnings and profits will not be taxable to a U.S. shareholder to the extent that they do not exceed the adjusted basis of the shareholder's shares, but rather will reduce the adjusted basis of such shares. To the extent that distributions in excess of current and accumulated earnings and profits exceed the adjusted basis of a U.S. shareholder's shares, such distributions will be included in income as long-term capital gain (or short-term capital gain if the shares have been held for 12 months or less) assuming the shares are a capital asset in the hands of the shareholder. In addition, any distribution declared by us in October, November or December of any year payable to a shareholder of record on a specified date in any such month shall be treated as both paid by Brandywine and received by the shareholder on December 31 of such year, provided that the distribution is actually paid by Brandywine not later than the end of January of the following calendar year. Shareholders may not include in their individual income tax returns any of Brandywine’s losses.

In general, a U.S. shareholder will recognize capital gain or loss on the disposition of common shares equal to the difference between the sales price for such shares and the adjusted tax basis for such shares. Gain or loss recognized upon a sale or exchange of common shares by a U.S. shareholder who has held such shares for more than one year will be treated as long-term capital gain or loss, respectively, and otherwise will be treated as short-term capital gain or loss. However, any loss upon a sale or exchange of shares by a U.S. shareholder who has held such shares for six months or less (after applying certain holding period rules) will be treated as a long-term capital loss to the extent such shareholder has received distributions from us required to be treated as long-term capital gain. U.S. shareholders who realize a loss on the sale or exchange of shares may be required to file IRS Form 8886, Reportable Transaction Disclosure Statement, if the loss exceeds certain thresholds (for individual taxpayers, the threshold is $2,000,000 for a loss in a single taxable year). U.S. shareholders should consult with their tax advisors regarding Form 8886 filing requirements.

Distributions from us and gain from the disposition of shares will not be treated as passive activity income and, therefore, U.S. shareholders will not be able to apply any “passive losses” against such income. Distributions from us (to the extent they do not constitute a return of capital or capital gain dividends) and, on an elective basis, capital gain dividends and gain from the disposition of shares will generally be treated as investment income for purposes of the investment income limitation.

Backup Withholding and Information Reporting

In general, Brandywine will report to its U.S. shareholders and the Internal Revenue Service the amount of distributions paid (unless the U.S. shareholder is an exempt recipient such as a corporation) during each calendar year, and the amount of tax withheld, if any. Under the backup withholding rules, a shareholder may be subject to backup withholding at the rate of 28% with respect to distributions paid unless such shareholder (a) is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact, or (b) provides a taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. A shareholder that does not provide us with his correct taxpayer identification number may also be subject to penalties imposed by the Internal Revenue Service. Any amount paid as backup withholding may be credited against the shareholder's income tax liability. In addition, we may be required to withhold a portion of capital gain distributions to any shareholders who fail to certify their non-foreign status to Brandywine. See “– Taxation of Foreign Shareholders.”

Taxation of Tax-Exempt Shareholders

Distributions by us to a shareholder that is a tax-exempt entity should not constitute “unrelated business taxable income” (“UBTI”), as defined in Section 512(a) of the Code provided that the tax-exempt entity has not financed the acquisition of its shares with “acquisition indebtedness” within the meaning of the Code and the shares are not otherwise used in an unrelated trade or business of the tax-exempt entity.

In the case of a “qualified trust” (generally, a pension or profit-sharing trust) holding shares in a REIT, the beneficiaries of the trust are treated as holding shares in the REIT in proportion to their actuarial interests in the qualified trust, instead of treating the qualified trust as a single individual (the “look-through exception”). A qualified trust that holds more than 10% of the shares of a REIT is required to treat a percentage of REIT dividends as UBTI if the REIT incurs debt to acquire or improve real property. This rule applies, however, only if (1) the qualification of the REIT depends upon the application of the “look through” exception (described above) to the restriction on REIT shareholdings by five or fewer individuals, including qualified trusts (see “Description of Shares of Beneficial Interest – Restrictions on Transfer”) and (2) the REIT is “predominantly held” by qualified trusts, i.e., if either (a) a single qualified trust holds more than 25% by value of the interests in the REIT or (b) one or more qualified trusts, each owning more than 10% by value, holds in the aggregate more than 50% of the interests in the REIT. The percentage of any dividend paid (or treated as paid) to such a qualified trust that is treated as UBTI is equal to the amount of modified gross income (gross income less directly connected expenses) from the unrelated trade or business of the REIT (treating the REIT as if it were a qualified trust), divided by the total modified gross income of the REIT. A de minimis exception applies where the percentage is less than 5%.

Taxation of Non-U.S. Shareholders

The rules governing United States Federal income taxation of nonresident alien individuals, foreign corporations, foreign partnerships and other shareholders that are not U.S. shareholders (collectively, “Non-U.S. Shareholders”) are complex and no attempt will be made herein to provide more than a summary of such rules. Prospective Non-U.S. Shareholders should consult with their own tax advisors to determine the impact of Federal, state and local income tax laws with regard to an investment in our shares, including any reporting requirements.

Distributions made by us that are not attributable to gain from sales or exchanges by us of United States real property interests and not designated by us as capital gains dividends will be treated as dividends of ordinary income to the extent that they are made out of current or accumulated earnings and profits of Brandywine. Such distributions will ordinarily be subject to a withholding tax equal to 30% of the gross amount of the distribution unless an applicable tax treaty reduces or eliminates that tax. However, if income from the investment in our shares is treated as effectively connected with the Non-U.S. Shareholder's conduct of a United States trade or business, the Non-U.S. Shareholder generally will be subject to a tax at graduated rates, in the same manner as U.S. shareholders are taxed with respect to such distributions (and may also be subject to the 30% branch profits tax in the case of a shareholder that is a foreign corporation). We expect to withhold United States income tax at the rate of 30% on the gross amount of any such distributions made to a Non-U.S. Shareholder unless (1) a lower treaty rate applies and the Non-U.S. shareholder files a W-8BEN (or applicable substitute form) or (2) the Non-U.S. Shareholder files an IRS Form W-8ECI with us claiming that the distribution is effectively connected income. Distributions in excess of our current and accumulated earnings and profits will not be taxable to a shareholder to the extent that such distributions do not exceed the adjusted basis of the shareholder's shares, but rather will reduce the adjusted basis of the shareholder in such shares. To the extent that distributions in excess of current and accumulated earnings and profits exceed the adjusted basis of a Non-Shareholder's shares, such distributions will give rise to tax liability if the Non-U.S. Shareholder would otherwise be subject to tax on any gain from the sale or disposition of its shares, as described below. If it cannot be determined at the time a distribution is made whether or not such distribution will be in excess of current and accumulated earnings and profits, the distributions will be subject to withholding at the same rate as dividends. However, amounts thus withheld are refundable to the shareholder if it is subsequently determined that such distribution was, in fact, in excess of our current and accumulated earnings and profits.

For any year in which Brandywine qualifies as a REIT, except as provided below for certain distributions after January 1, 2005, distributions that are attributable to gain from sales or exchanges by us of United States real property interests will be taxed to a Non-U.S. Shareholder under the provisions of the Foreign Investment in Real Property Tax Act of 1980 (“FIRPTA”). Under FIRPTA, distributions attributable to gain from sales of United States real property interests are taxed to a Non-U.S. Shareholder as if such gain were effectively connected with a United States business. Individuals who are Non-U.S. Shareholders will be required to report such gain on a U.S. federal income tax return and such gain will taxed at the normal capital gain rates applicable to U.S. individual shareholders (subject to applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals). Also, distributions subject to FIRPTA may be subject to a 30% branch profits tax in the hands of a foreign corporate shareholder not entitled to treaty relief. Brandywine is required by applicable Treasury Regulations to withhold 35% of any distribution that could be designated by us as a capital gains dividend. The amount is creditable against the Non-U.S. Shareholder's U.S. tax liability.

For distributions after January 1, 2005, the Act provides that distributions attributable to gain from sales or exchanges by us of United States real property interests are treated as ordinary dividends (not subject to FIRPTA) if the distribution is made to a Non-U.S. Shareholder with respect to any class of stock which is “regularly traded” on an established securities market located in the United States and if the Non-U.S. shareholder did not own more than 5% of such class of stock at any time during the taxable year. Accordingly, such distributions will generally be subject to a 30% U.S. withholding tax (subject to reduction under applicable treaty) and a Non-U.S. Shareholder will not be required to report the distribution on a U.S. tax return. In addition, the branch profits tax will not apply to such distributions.

Gain recognized by a Non-U.S. Shareholder upon a sale of shares generally will not be taxed under FIRPTA if Brandywine is a “domestically controlled REIT,” defined generally as a REIT in which at all times during a specified testing period less than 50% in value of the shares of beneficial interest was held directly or indirectly by foreign persons. It is currently anticipated that we will be a “domestically controlled REIT,” and therefore the sale of shares by a Non-U.S. Shareholder will not be subject to taxation under FIRPTA. However, because the shares may be traded, we cannot be sure that we will continue to be a “domestically controlled REIT.” Gain not subject to FIRPTA will be taxable to a Non-U.S. Shareholder if (1) investment in the shares is effectively connected with the Non-U.S. Shareholder's United States trade or business, in which case the Non-U.S. Shareholder will be subject to the same treatment as U.S. shareholders with respect to such gain or (2) the Non-U.S. Shareholder is a nonresident alien individual who was present in the United States for 183 days or more during the taxable year, in which case the nonresident alien individual will be subject to a 30% tax on the individual's capital gains. If the gain on the sale of shares were to be subject to taxation under FIRPTA, the Non-U.S. Shareholder would be subject to the same treatment as U.S. shareholders with respect to such gain (subject to applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals).

If we were not a domestically controlled REIT, a sale of common shares by a Non-U.S. shareholder would not be subject to taxation under FIRPTA as a sale of a U.S. real property interest if (1) our preferred shares or common shares were “regularly traded” on an established securities market within the meaning of applicable Treasury regulations and (2) the Non-U.S. shareholder did not actually, or constructively under specified attribution rules under the Code, own more than 5% of our preferred shares or common shares at any time during the shorter of the five-year period preceding the disposition or the holder’s holding period.

Even if our common shares were not regularly traded on an established securities market, a Non-U.S. shareholder would not be subject to taxation under FIRPTA as a sale of a U.S. real property interest if such Non-U.S. shareholder’s common shares had a fair market value on the date of acquisition that was equal to or less than 5% of our regularly traded class of shares with the lowest fair market value. For purposes of this test, if a Non-U.S. shareholder acquired shares of common shares and subsequently acquired additional shares at a later date, then all such shares would be aggregated and valued as of the date of the subsequent acquisition.

Statement of Share Ownership

Brandywine is required to demand annual written statements from the record holders of designated percentages of our shares disclosing the actual owners of the shares. Brandywine must also maintain, within the Internal Revenue District in which it is required to file its federal income tax return, permanent records showing the information Brandywine has received as to the actual ownership of such shares and a list of those persons failing or refusing to comply with such demand.

Other Tax Consequences

Brandywine, the Operating Partnership, the Subsidiary Partnerships and Brandywine’s shareholders may be subject to state or local taxation in various state or local jurisdictions, including those in which it or they transact business or reside. The state and local tax treatment of Brandywine, the Operating Partnership, the Subsidiary Partnerships and Brandywine’s shareholders may not conform to the Federal income tax consequences discussed above. Consequently, prospective shareholders should consult their own tax advisors regarding the effect of state and local tax laws on an investment in our securities.

Possible Federal Tax Developments

The rules dealing with Federal income taxation are constantly under review by the Internal Revenue Service, the Treasury Department and the Congress. New Federal tax legislation or other provisions may be enacted into law or new interpretations, rulings, Treasury Regulations or court decisions could be adopted, all of which could adversely affect the taxation of Brandywine or of its shareholders. We cannot predict the likelihood of passage of any new tax legislation or other provisions or court decisions either directly or indirectly affecting us or our shareholders. Consequently, the tax treatment described herein may be modified prospectively or retroactively by legislative, judicial or administrative action.
