Certain terms of the Notes will be established pursuant to an Officers Certificate to the Base Indenture (together with

The Operating Partnership understands that the Underwriters propose to make a public offering of the Notes on the terms and in the manner set forth herein and as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Operating Partnership and Federal Realty Investment Trust (the “Company”), a Maryland real estate investment trust and the owner of 100% of the limited liability company interests of Federal Realty GP LLC (the “General Partner”), the sole general partner of the Operating Partnership, have jointly prepared and filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (File No. 333-262016 and 333-262016 -01), including a prospectus, dated January 5, 2022 (the “Base Prospectus”), which registration statement became effective upon filing under Rule 462(e) of the rules and regulations of the Commission (the “1933 Act Regulations”) under the Securities Act of 1933, as amended (the “1933 Act”).

Except as disclosed in or contemplated by the Registration Statement, the General Disclosure Package and the Prospectus (including with respect to restrictions on transfer of property or assets pursuant to the terms of mortgage debt on any properties held directly or indirectly by the Operating Partnership or pursuant to the express terms of any joint venture arrangement of the Operating Partnership or any of its subsidiaries), no subsidiary of the Operating Partnership is currently prohibited, directly or indirectly, from paying any distributions to the Operating Partnership to the extent permitted by applicable law, from making any other distribution on the equity held by the Operating Partnership, or from repaying to the Operating Partnership any loans or advances made by the Operating Partnership to any such subsidiary.

(23)    REIT Qualification. With respect to all tax periods regarding which the Internal Revenue Service is or will be entitled to assert any claim, the Company has met the requirements for qualification as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and the Company’s present and contemplated operations, assets and income meet and will enable it to continue to meet such requirements.

(24)    Operating Partnership Tax Status. Since it became a subsidiary of the Company, the Operating Partnership has been and will continue to be classified as a disregarded entity or a partnership that is not a “publicly traded partnership” taxable as a corporation for U.S. federal income tax purposes.

(26)    Tax Compliance.

12

taxes as (i) are not yet due, (ii) are being contested in good faith by appropriate proceedings diligently conducted and for which adequate reserves are being maintained in accordance with GAAP, or (iii) could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(27)    Possession of Licenses and Permits. The Federal Entities hold all material licenses, certificates and permits from governmental authorities which are necessary to the conduct of their respective businesses; and none of the Federal Entities have infringed any patents, patent rights, trade names, trademarks or copyrights, which infringement is material to the business of the Federal Entities, considered as one enterprise.

(29)    Environmental Laws. Although the Company and the Operating Partnership are aware of the presence of hazardous substances, hazardous materials, toxic substances or waste materials (“Hazardous Materials”) on certain of the properties of the Federal Entities, nothing has come to the attention of the Company or the Operating Partnership which, at this time, would lead the Company or the Operating Partnership to believe that the presence of such Hazardous Materials, when considered in the aggregate, would materially adversely affect the financial condition of the Operating Partnership. In connection with the construction on or operation and use of the properties owned or leased by the Federal Entities, the Company and the Operating Partnership represent that, as of the date hereof, it has no knowledge of any material failure by the Federal Entities to comply with all applicable local, state and federal environmental laws, regulations, ordinances and administrative and judicial orders relating to the generation, recycling, reuse, sale, storage, handling, transport and disposal of any Hazardous Materials.

13

(33)    Foreign Corrupt Practices Act. None of the Federal Entities nor, to the knowledge of the Company or the Operating Partnership, any director, trustee, officer, agent, employee or other person associated with or acting on behalf of any Federal Entity, has violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977, as amended, or the Bribery Act 2010 of the United Kingdom, and the Federal Entities have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

(34)    Money Laundering Laws. The operations of the Federal Entities are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the money laundering statutes and the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving any Federal Entity with respect to the Money Laundering Laws is pending or, to the knowledge of the Company or the Operating Partnership, threatened.

(35)    OFAC. None of the Federal Entities nor, to the knowledge of the Company or the Operating Partnership, any director, trustee, officer, agent, employee or affiliate of any Federal Entity is (i) currently subject to any sanctions administered or enforced by the U.S. Government (including, without limitation, the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”) or other relevant sanctions authority (collectively, “Sanctions”)); or (ii) located, organized or resident in a country or territory that is, or whose government is, the subject of Sanctions, including, without limitation, Cuba, Iran, North Korea, Russia, Syria, the Crimea region of Ukraine and the non-government controlled areas of the Zaporizhzhia and Kherson Regions of Ukraine, the so-called Donetsk People’s Republic, and the so-called Luhansk People’s Republic, that broadly prohibit dealings with that country or territory (each, a “Sanctioned Country”); and the Federal Entities will not directly or indirectly use the proceeds of the offering of the Notes hereunder, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any Sanctions.

(36)    Cybersecurity. (i) To the knowledge of the Company and the Operating Partnership, there has been no security breach or incident, unauthorized access or disclosure, or other compromise relating to any Federal Entity’s information technology and computer systems, networks, hardware, software, data and databases (including the data and information of their respective customers, employees, suppliers, vendors and any third party data maintained, processed or stored by any Federal Entity, and any such data processed or stored by third parties on behalf of any Federal Entity), equipment or technology (collectively, “IT Systems and Data”); (ii) no Federal Entity has been notified of, and neither the Company nor the Operating Partnership has knowledge of any event or condition that could result in, any security breach or incident, unauthorized access or disclosure or other compromise to any Federal Entity’s IT Systems and Data; and (iii) the Federal Entities have implemented appropriate controls, policies, procedures, and

technological safeguards to maintain and protect the integrity, continuous operation, redundancy and security of their IT Systems and Data reasonably consistent with industry standards and practices, or as required by applicable regulatory standards, except, in each case with respect to clauses (i) and (ii) above, as would not, individually or in the aggregate, have a Material Adverse Effect, and except, in the case of clause (iii) above, where the failure to do so would not, individually or in the aggregate, have a Material Adverse Effect. The Federal Entities are presently in material compliance with all applicable laws or statutes and all judgments, orders, rules and regulations of any court or arbitrator or governmental or regulatory authority, internal policies and contractual obligations relating to the privacy and security of IT Systems and Data and to the protection of such IT Systems and Data from unauthorized use, access, misappropriation or modification, except where the failure to be so in material compliance would not, individually or in the aggregate, have a Material Adverse Effect.

(b)    Officers’ Certificates. Any certificate signed by any officer of the Company or the Operating Partnership or any authorized representative of the Company or the Operating Partnership delivered to the Representatives or to counsel for the Underwriters in connection with the offering of the Notes shall be deemed a representation and warranty by the Company or the Operating Partnership, as the case may be, to each Underwriter as to the matters covered thereby on the date of such certificate and, unless subsequently amended or supplemented, at each Representation Date subsequent thereto.

SECTION 3    Covenants of the Operating Partnership.

The Operating Partnership covenants with each Underwriter as follows:

(a)    Compliance with Securities Regulations and Commission Requests; Payment of Filing Fees. The Operating Partnership, subject to Section 3(e), will comply with the requirements of Rule 430B and during the period a prospectus relating to the Notes is (or, but for the exception afforded by Rule 172 of the 1933 Act Regulations would be) required by the 1933 Act to be delivered in connection with any sales of the Notes, will notify the Representatives immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement or new registration statement relating to the Notes shall become effective, or any supplement to the Prospectus or any amended Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or the filing of a new registration statement or any amendment or supplement to the Prospectus or any document incorporated by reference therein or otherwise deemed to be a part thereof or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or such new registration statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Notes for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Operating Partnership becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Notes. The Operating Partnership will effect the filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Operating Partnership will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment. The Operating Partnership shall pay the required Commission filing fees relating to the Notes within the time required by Rule 456(b)(1) (i) of the 1933 Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the 1933 Act Regulations (including, if applicable, by updating the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b)).

16

(b)    Delivery of Registration Statements. The Operating Partnership has furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, signed copies of the Original Registration Statement and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein or otherwise deemed to be a part thereof) and signed copies of all consents and certificates of experts, and will also deliver to the Representatives, without charge, a conformed copy of the Original Registration Statement and of each amendment thereto (without exhibits) for each of the Underwriters. The copies of the Original Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(c)    Delivery of Prospectus(es). The Operating Partnership has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Operating Partnership has delivered to each Underwriter, without charge, as many copies of each Issuer Free Writing Prospectus, if any, as such Underwriter reasonably requested, and the Operating Partnership hereby consents to the use of such copies of each preliminary prospectus and each Issuer Free Writing Prospectus, if any, for purposes permitted by the 1933 Act. The Operating Partnership will furnish to each Underwriter, without charge, during the period when a prospectus is required to be delivered under the 1933 Act in connection with sales of the Notes, such number of copies of the prospectus, as amended or supplemented, as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. The Operating Partnership, during the period when the Prospectus is required to be delivered under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the rules and regulations of the Commission thereunder.

(d)    Notice and Effect of Material Events. The Operating Partnership will comply with the 1933 Act and the rules and regulations of the Commission thereunder, the 1934 Act and the rules and regulations of the Commission thereunder and the 1939 Act and the rules and regulations of the Commission thereunder so as to permit the completion of the distribution of the Notes as contemplated in this Agreement and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Notes, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Operating Partnership, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or to file a new registration statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the rules and regulations thereunder, the Operating Partnership will promptly prepare and file with the

17

Commission, subject to Section 5(a) hereof, such amendment, supplement or new registration statement as may be necessary to correct such statement or omission or to comply with such requirements, the Operating Partnership will use its reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable (if it is not an automatic shelf registration statement with respect to the Notes) and the Operating Partnership will furnish to the Underwriters such number of copies of such amendment, supplement or new registration statement as the Representatives may reasonably request. If, during the time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Notes and following issuance of an Issuer Free Writing Prospectus, there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement (or any other registration statement relating to the Notes) or the Statutory Prospectus or any preliminary prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Operating Partnership will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(e)    Filing of Amendments and 1934 Act Documents; Preparation of the Final Term Sheet. From the Applicable Time to the Closing Time, the Operating Partnership will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement or new registration statement relating to the Notes or any amendment, supplement or revision to either any preliminary prospectus (including any prospectus included in the Original Registration Statement or amendment thereto at the time it became effective) or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, and the Operating Partnership will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object. The Operating Partnership has given the Representatives notice of any filings made pursuant to the 1934 Act or the Commission’s regulations thereunder within forty-eight hours prior to the Applicable Time. The Operating Partnership will prepare a final term sheet (the “Final Term Sheet”) reflecting the final terms of the Notes, substantially in the form set forth on Schedule 4 hereto, and shall file such Final Term Sheet as an “issuer free writing prospectus” pursuant to Rule 433 prior to the close of business two business days after the date hereof; provided that the Operating Partnership shall furnish the Representatives with copies of such Final Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall reasonably object.

(f)    Blue-Sky Qualifications. The Operating Partnership shall use its best efforts, in cooperation with the Underwriters, to qualify the Notes for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Underwriters may designate and to maintain such qualifications in effect for a period of not less than one year from the date of this Agreement; provided, however, that the Operating Partnership shall not be obligated to file any general consent to service of process or to qualify or register as a foreign partnership or as a dealer in securities in any jurisdiction in which it is not so qualified or registered, or provide any undertaking or make any change in its charter or by-laws that the

18

Board of Trustees of the Company reasonably determines to be contrary to the best interests of the Operating Partnership and its unitholders or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Notes have been so qualified or registered, the Operating Partnership shall file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the date of this Agreement. The Operating Partnership will also supply the Underwriters with such information as is necessary for the determination of the legality of the Notes for investment under the laws of such jurisdictions as the Underwriters may request.

(g)    Stop Order by State Securities Commission. The Operating Partnership shall advise the Underwriters promptly and, if requested by any Underwriter, to confirm such advice in writing, of the issuance by any state securities commission of any stop order suspending the qualification or exemption from qualification of any of the Notes for offering or sale in any jurisdiction, or the initiation of any proceeding for such purpose by any state securities commission or other regulatory authority. The Operating Partnership shall use its reasonable best efforts to prevent the issuance of any stop order or order suspending the qualification or exemption of any of the Notes under any state securities or Blue Sky laws, and if at any time any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption of any of the Notes under any state securities or Blue Sky laws, the Operating Partnership shall use its reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time.

(h)    Earnings Statement. The Operating Partnership shall timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement (in form complying with Rule 158 of the 1933 Act Regulations) for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(i)    Reporting Requirements. The Operating Partnership, during the period when a prospectus is required to be delivered (or but for Rule 172 of the 1933 Act Regulations would be required to be delivered) under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations.

(j)    Issuer Free Writing Prospectuses. The Operating Partnership represents and agrees that, unless it obtains the prior written consent of the Underwriters, and each Underwriter represents and agrees that, unless it obtains the prior written consent of the Operating Partnership and the other Underwriters, it has not made and will not make any offer relating to the Notes that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, in each case required to be filed with the Commission; provided, however, that prior to the preparation of the Final Term Sheet in accordance with Section 3(e) hereof, the Underwriters are authorized to use the information with respect to the final terms of the Notes in communications conveying information relating to the offering to investors. Any such free writing prospectus consented to by the Operating Partnership and the Underwriters is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Operating Partnership represents that it has treated or agrees that it

19

will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

(k)    REIT Qualification. For any taxable years in which the Closing Time occurs, the Company will use its best efforts to continue to meet the requirements to qualify as a “real estate investment trust” under the Code, and the Operating Partnership will use its best efforts to maintain its classification for U.S. federal income tax purposes as a disregarded entity or partnership that is not a “publicly traded partnership” taxable as a corporation, in each case until any such time that the board of trustees of the Company determines that it is no longer in the best interests of the Company to so qualify or for the Operating Partnership to maintain such classification.

(l)    Use of Proceeds. The Operating Partnership shall use the net proceeds received by it from the sale of the Notes in the manner specified in the General Disclosure Package and the Prospectus under “Use of Proceeds.”

(m)    Limitations on Sales of Substantially Similar Notes During the period beginning on and including the date of this Agreement and continuing through the Closing Time, the Operating Partnership will not offer, sell, contract to sell, pledge or otherwise issue any debt securities of the Operating Partnership which mature more than one year after such Closing Time and which are substantially similar to such Notes, without the prior written consent of the Representatives.

SECTION 4    Payment of Expenses.

(a)    Expenses. The Operating Partnership covenants and agrees with the several Underwriters that the Operating Partnership will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Operating Partnership’s counsel and accountants in connection with the registration of the Notes under the 1933 Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, any preliminary prospectus, Permitted Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any Agreement Among Underwriters, this Agreement, any Indenture, any Blue Sky and legal investment surveys and any other documents in connection with the offering, purchase, sale and delivery of the Notes; (iii) all expenses in connection with the qualification of the Notes for offering and sale under state securities laws as provided in Section 3(g) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky and legal investment surveys; (iv) any fees charged by securities rating services for rating the Notes; (v) any filing fees incident to any required review by FINRA of the terms of the sale of the Notes; (vi) the fees and expenses of any Trustee and any agent of any Trustee and the fees and disbursements of counsel for any Trustee in connection with any Indenture and the Notes; (vii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section 4; (viii) the costs and expenses (including without limitation any damages or other amounts payable in connection with legal or

(b)    Termination of Agreement.

SECTION 6    Indemnification.

(a)    Indemnification of Underwriters. The Operating Partnership, agrees to indemnify and hold harmless each Underwriter, its affiliates, its directors, its officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, any preliminary prospectus supplement, Issuer Free Writing Prospectus, the Registration Statement (including the Rule 430B Information), the Prospectus, as amended or supplemented, or any other prospectus relating to the Notes, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Operating Partnership shall not be liable in any such case to the extent that any such loss, claim, damage or liability (or actions in respect thereof) arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus, any preliminary prospectus supplement, Issuer Free Writing Prospectus, the Registration Statement, the Prospectus, as amended or supplemented, or any other prospectus relating to the Notes, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Operating Partnership by any Underwriter of the Notes through the Representatives expressly for use therein.

(b)    Indemnification of Operating Partnership. Each Underwriter, severally and not jointly, will indemnify and hold harmless the Operating Partnership, its officers who signed the

24

Registration Statement and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities to which any of the foregoing persons in this subsection (b) may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, any preliminary prospectus supplement, Issuer Free Writing Prospectus, the Registration Statement, the Prospectus, as amended or supplemented, or any other prospectus relating to the Notes, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any preliminary prospectus, any preliminary prospectus supplement, Issuer Free Writing Prospectus, the Registration Statement, the Prospectus, as amended or supplemented, or any other prospectus relating to the Notes, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Operating Partnership by such Underwriter through the Representatives expressly for use therein; and will reimburse such foregoing persons for any legal or other expenses reasonably incurred thereby in connection with investigating or defending any such action or claim as to which such foregoing persons shall be entitled to indemnification under this subsection (b) as such expenses are incurred. The Operating Partnership hereby acknowledges that the only information furnished to the Operating Partnership by any Underwriter through the Representatives expressly for use in any preliminary prospectus, any preliminary prospectus supplement, Issuer Free Writing Prospectus, the Registration Statement, the Prospectus, as amended or supplemented, or any other prospectus relating to the Notes, or any such amendment or supplement are the statements set forth in (i) the names of the Underwriters contained on the cover page and on the back page of the Prospectus and in the table under the caption “Underwriting (Conflicts of Interest)” in the Prospectus and (ii) the seventh, ninth and tenth paragraph under the caption “Underwriting (Conflicts of Interest)” in the Prospectus.

(c)    Actions Against Parties; Notification. Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel (unless separate counsel is required due to conflict of interest) or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of

25

investigation. No indemnifying party shall, without written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

SECTION 7    Contribution.

If the indemnification provided for in Section 6 is unavailable to or insufficient to hold harmless an indemnified party under subsection 6(a) or 6(b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Operating Partnership on the one hand and the Underwriters on the other from the offering of the Notes to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under SECTION 6(c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Operating Partnership on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations.

The relative benefits received by the Operating Partnership on the one hand and such Underwriters on the other, in connection with the offering of the Notes pursuant to this Agreement, shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes (before deducting expenses) received by the Operating Partnership, and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate initial public offering price of the Notes.

The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Operating Partnership on the one hand or such Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Operating Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.

26

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

The obligations of the Underwriters in this Section 7 to contribute are several in proportion to their respective underwriting obligations with respect to the Notes and not joint.

The obligations of the Operating Partnership under this Section 7 shall be in addition to any liability which the Operating Partnership may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of the Underwriters under this Section 7 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer of the Operating Partnership who signed the Registration Statement, and to each person, if any, who controls the Operating Partnership within the meaning of the 1933 Act.

SECTION 8    Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Operating Partnership or the Company, or authorized representatives of the Operating Partnership or the Company submitted pursuant hereto shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or its affiliates or selling agents, any person controlling any Underwriter, its officers or directors or any person controlling the Operating Partnership or the Company, and (ii) delivery of and payment for the Notes.

SECTION 9    Termination.

(a)    Termination; General. The Representatives may terminate this Agreement, by notice to the Operating Partnership, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement, any Material Adverse Effect, whether or not arising in the ordinary course of business, the effect of which is such as to make it, in the reasonable judgment of the Underwriters, impracticable or inadvisable to proceed with the offering or delivery of the Notes as contemplated in the Registration Statement, the Prospectus or the General Disclosure Package, or (ii) if there has occurred (A) any material adverse change in the financial markets in the United States or the international financial markets, (B) any outbreak of hostilities or escalation thereof or other calamity or crisis, (C) a declaration by the United States of a national emergency or war, or (D) any change or development involving a prospective change in national or international political, financial, or economic conditions, in each case, the

27

effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Notes or to enforce contracts for the sale of the Notes, or (iii) (x) if trading in any securities of the Company or the Operating Partnership has been suspended or materially limited by the Commission or the NYSE, or (y) if trading generally on the NYSE, the Nasdaq Global Market or the NYSE American or in the over-the-counter market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal, New York or Delaware authorities, or (v) a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred, or (vi) if the rating assigned by any nationally recognized statistical rating organization to any debt securities of the Operating Partnership as of the date hereof shall have been downgraded, or withdrawn, since such date or if any such rating organization shall have publicly announced that it has placed any series of debt securities of the Operating Partnership under surveillance or review as to the rating of such debt securities or any of the Operating Partnership’s other securities, which does not indicate affirmation or improvement in the rating.

(b)    Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided, further, that Sections 1, 6, 7, 8, 9, 13 and 14 hereof shall survive such termination and remain in full force and effect.

SECTION 10    Default by One or More of the Underwriters.

(a)    Effect of Default by One or More of the Underwriters. If any Underwriter shall default in its obligation to purchase the Notes which it has agreed to purchase at the Closing Time under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Notes on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Notes, then the Operating Partnership shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Notes on such terms. In the event that, within the respective prescribed period, the Representatives notify the Operating Partnership that they have so arranged for the purchase of such Notes, or the Operating Partnership notifies the Representatives that it has so arranged for the purchase of such Notes, the Representatives or the Operating Partnership shall have the right to postpone the Closing Time for such Notes for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, as amended or supplemented, or in any other documents or arrangements, and the Operating Partnership agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such Notes.

(b)    Effect of Default to Non-Defaulting Underwriter. If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the Representatives and the Operating Partnership as provided in subsection (a) above, the aggregate

28

principal amount of such Notes which remains unpurchased does not exceed one-tenth of the aggregate principal amount of the Notes to be purchased at the Closing Time, then the Operating Partnership shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes which such Underwriter agreed to purchase at the Closing Time under this Agreement relating to such Notes and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Notes which such Underwriter agreed to purchase under this Agreement) of the Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made, but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c)    Termination Pursuant to Default. If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the Representatives and the Operating Partnership as provided in subsection (a) above, the aggregate principal amount of Notes which remains unpurchased exceeds one-tenth of the aggregate principal amount of the Notes to be purchased at the Closing Time, as referred to in subsection (b) above, or if the Operating Partnership shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Notes of a defaulting Underwriter or Underwriters, then, in the case of a failure to purchase Notes at the Closing Time, this Agreement relating to such Notes shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Operating Partnership, except for the expenses to be borne by the Operating Partnership and the Underwriters as provided in Section 4(a) hereof and the indemnity and contribution agreements in Section 6 and Section 7 hereof, but nothing herein shall relieve a defaulting Underwriter from liability for its default.

SECTION 11    Notices.

In all dealings hereunder, the Representatives of the Underwriters of Notes shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in this Agreement.

SECTION 15    Recognition of the U.S. Special Resolution Regimes.

In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Holder in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be on April 15 and October 15 (whether or not a Business Day, as defined below), as the case may be, next preceding such Interest Payment Date at the office or agency of the Company maintained for such purpose; provided, however, that such interest may be paid, at the Company’s option, by mailing a check to such Holder at its registered address or by transfer of funds to an account maintained by such Holder within the United States. Any such

interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date, and may be paid to the Holder in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee referred to on the reverse hereof, notice whereof shall be given to Holders of Notes of this series not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

If any Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, principal, premium, if any, and/or interest payable with respect to such Interest Payment Date or Maturity Date, as the case may be, will be paid on the next succeeding Business Day with the same force and effect as if it were paid on the date such payment was due, and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date or Maturity Date, as the case may be. “Business Day” means any day, other than a Saturday or Sunday, on which banks in The City of New York and the City of Charlotte, State of North Carolina, are not required or authorized by law or executive order to close.

FEDERAL REALTY OP LP

5.375% Note due 2028

This Note is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of September 1, 1998, as amended by the First Supplemental Indenture, dated as of January 5, 2022 (herein called the “Indenture”), between the Company, as successor to Federal Realty Investment Trust, and U.S. Bank Trust Company, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Note is a part), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Note is one of the duly authorized series of Securities designated as “5.375% Notes due 2028” (collectively, the “Notes”), and the aggregate principal amount of the Notes to be issued under such series is limited to $350,000,000 as of the date hereof (except for Notes authenticated and delivered upon transfer of, or in exchange for, or in lieu of other Notes). The Company may, without the consent of the Holders of any Securities, create and issue additional notes in the future having the same terms other than the date of original issuance, the issue price and the date on which interest begins to accrue so as to form a single series with the Notes. The Notes are the unsecured and unsubordinated obligations of the Company and rank equally with all existing and future unsecured and unsubordinated indebtedness of the Company. All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

If an Event of Default, as defined herein, shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

As used herein:

“Event of Default” means any one of the following events (whatever the reason for such Event of Default and whether or not it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1)    default in the payment of any interest upon or any Additional Amounts payable in respect of the Notes when such interest or Additional Amounts becomes due and payable, and continuance of such default for a period of 30 days;

(2)    default in the payment of the principal of (or premium, if any, on) the Notes when it becomes due and payable at its Maturity;

(3)    default in the deposit of any sinking fund payment, when and as due by the terms of the Notes;

(4)    default in the performance, or a breach, of any covenant or agreement by the Company under the Indenture (other than a covenant or agreement a default in whose performance or whose breach is elsewhere in this definition of Event of Default specifically dealt with), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” under the Indenture;

(5)    default under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company (including obligations under leases required to be reflected on the balance sheet of the lessee as financing lease liabilities under generally accepted accounting principles but not including any indebtedness or obligations for which recourse is limited to one or more properties) in an aggregate principal amount in excess of $50,000,000 or under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company (including such leases but not including such indebtedness or obligations for which recourse is limited to one or more properties) in an aggregate principal amount in excess of $50,000,000 by the Company, whether such indebtedness now exists or shall hereafter be created, which default shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable or such obligations being accelerated, without such acceleration having been rescinded or annulled;

(6)    a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(a)    is for relief against the Company or any Significant Subsidiary in an involuntary case,

(b)    appoints a Custodian of the Company or any Significant Subsidiary or for all or substantially all of either of its property, or

(c)    orders the liquidation of the Company or any Significant Subsidiary, and the order or decree remains unstayed and in effect for 90 days; or

(7)    the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(a)    commences a voluntary case or proceeding,

(b)    consents to the entry of an order for relief against it in an involuntary case or proceeding,

(c)    consents to the appointment of a Custodian of it or for all or substantially all of its property, or

5

(d)    makes a general assignment for the benefit of its creditors.

The defeasance and covenant defeasance provisions of the Indenture apply to the Notes. The Notes will not be entitled to the benefits of any sinking fund.

The Notes are subject to redemption at any time, in whole or in part, at the election of the Company.

Prior to April 1, 2028, (the “Par Call Date”), the Company may redeem the Notes, at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus thirty (30) basis points less (b) interest accrued to, but excluding, the date of redemption, and

(2) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

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

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

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on

6

H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

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

Notice of any redemption of the Notes will be given by mail or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) to Holders of Securities, not less than 10 nor more than 60 days prior to the Redemption Date, all as provided in the Indenture.

In the event of redemption of this Note in part only, a new Note or Notes for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of all Securities issued under the Indenture at the time Outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of not less than a majority of the aggregate principal amount of the Outstanding Securities, on behalf of the Holders of all such Securities, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in

7

the Indenture permit the Holders of not less than a majority of the aggregate principal amount, in certain instances, of the Outstanding Securities of any series to waive, on behalf of all of the Holders of Securities of such series, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and other Notes issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed.

The Company will not, and will not permit any Subsidiary to, incur any Debt (as defined below) if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds thereof, the aggregate principal amount of all outstanding Debt of the Company and its Subsidiaries on a consolidated basis determined in accordance with generally accepted accounting principles is greater than 60% of the sum of (without duplication) (i) Total Assets as of the end of the calendar quarter covered in the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Securities and Exchange Commission (or, if such filing is not permitted under the Securities Exchange Act of 1934, with the Trustee) prior to the incurrence of such additional Debt and (ii) the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or any Subsidiary since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Debt.

In addition to the foregoing limitation on the incurrence of Debt, the Company will not, and will not permit any Subsidiary to, incur any Debt secured by any mortgage, lien, charge, pledge, encumbrance or security interest of any kind upon any property of the Company or any Subsidiary if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds thereof, the aggregate principal amount of all outstanding Debt of the Company and its Subsidiaries on a consolidated basis which is secured by any mortgage, lien, charge, pledge, encumbrance or security interest on property of the Company or any Subsidiary is greater than 40% of the sum of (without duplication) (1) Total Assets as of the end of the calendar quarter covered in the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Securities and Exchange Commission (or, if such filing is not permitted under the Securities Exchange Act of 1934, with the Trustee) prior to the incurrence of such additional Debt and (2) the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or any Subsidiary since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Debt; provided, however, that for purposes of this limitation, the amount of obligations under capital leases shown as a liability on the Company’s consolidated balance sheet shall be deducted from Debt and from Total Assets.

8

Furthermore, the Company will not, and will not permit any Subsidiary to, incur any Debt if the ratio of Consolidated Income Available for Debt Service (as defined below) to the Annual Debt Service Charge (as defined below) for the four consecutive fiscal quarters most recently ended prior to the date on which such additional Debt is to be incurred shall have been less than 1.5 to 1, on an unaudited pro forma basis after giving effect thereto and to the application of the proceeds therefrom, and calculated on the assumption that: (i) such Debt and any other Debt incurred by the Company and its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Debt, had occurred at the beginning of such period; (ii) the repayment or retirement of any other Debt by the Company and its Subsidiaries since the first day of such four-quarter period had been repaid or retired at the beginning of such period (except that, in making such computation, the amount of Debt under any revolving credit facility shall be computed based upon the average daily balance of such Debt during such period); (iii) in the case of Acquired Debt or Debt incurred in connection with any acquisition since the first day of such four-quarter period, the related acquisition had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition being included in such unaudited pro forma calculation; and (iv) in the case of any acquisition or disposition by the Company or its Subsidiaries of any asset or group of assets since the first day of such four-quarter period, whether by merger, stock purchase or sale, or asset purchase or sale, such acquisition or disposition or any related repayment of Debt had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition or disposition being included in such unaudited pro forma calculation.

Furthermore, the Company and its Subsidiaries taken as a whole, will, at all times maintain an Unencumbered Total Asset Value (as defined below) in an amount not less than 150% of the aggregate outstanding principal amount of the unsecured Debt of the Company and its Subsidiaries, taken as a whole.

Ladies and Gentlemen:

We have acted as federal income tax counsel to (i) Federal Realty Investment Trust, a Maryland real estate investment trust (the “Company”), and (ii) Federal Realty OP LP, a Delaware limited partnership (the “Partnership”). You have requested certain opinions regarding the application of U.S. federal income tax laws to the Company in connection with the filing of a prospectus supplement dated April 10, 2023 (the “Prospectus Supplement”) to a prospectus of the Company and the Partnership (the “Base Prospectus”) filed as part of a registration statement on Form S-3 (File No. 333-262016, the “Registration Statement,” which term includes the Base Prospectus, Prospectus Supplement, and all documents incorporated and deemed to be incorporated by reference therein) with the Securities and Exchange Commission.

In rendering the following opinions, we have examined such statutes, regulations, records, certificates and other documents as we have considered necessary or appropriate as a basis for such opinions, including the following: (1) the Registration Statement, (2) the Declaration of Trust of the Company (the “Declaration of Trust”), the Amended and Restated Bylaws of the Company, the Certificate of Limited Partnership of the Partnership, and the Agreement of Limited Partnership of the Partnership (the “Partnership Agreement”), each as amended, restated or supplemented, if applicable, (3) certain written representations of the Company contained in a letter to us dated the date hereof, a copy of which is attached as Schedule 1 hereto, (4) copies of the representative leases entered into by the Company as of the date hereof, and (5) such other documents or information as we have deemed necessary to render the opinions set forth in this letter. In our review, we have assumed, with your consent, that all of the representations and statements set forth in such documents as to factual matters (but not legal conclusions) are true and correct, and all of the obligations imposed by any such documents on the parties thereto, including obligations imposed under the Declaration of Trust and the Partnership Agreement, have been or will be performed or satisfied in accordance with their terms. We also have assumed the genuineness of all signatures, the proper execution of all documents, the authenticity of all documents submitted to us as originals, the conformity to originals of documents submitted to us as copies, and the authenticity of the originals from which any copies were made.

Unless facts material to the opinions expressed herein are specifically stated to have been independently established or verified by us, we have relied as to such facts solely upon the representations made by the Company. To the extent that the representations of the Company are with respect to matters set forth in the Internal Revenue Code of 1986, as amended (the “Code”) or the regulations promulgated thereunder (the “Treasury Regulations”), we have reviewed with the individuals making such representations the relevant provisions of the Code, the applicable Treasury Regulations and published administrative interpretations thereof. We assume that each representation made by the Company is and will be true, correct and complete, and that all representations that speak in the future, or to the intention, or to the best of belief and knowledge of any person(s) or party(ies) are and will be true, correct and complete as if made without such qualification. Nothing has come to our attention which would cause us to believe that any of such representations are untrue, incorrect or incomplete.

Based upon and subject to the foregoing and to the qualifications below, we are of the opinion that (i) the Company qualified as a real estate investment trust, or REIT, under the Code for each of its taxable years ending after December 31, 1986 and before January 1, 2023; and the Company qualified as a REIT under the Internal Revenue Code of 1954 for each of its taxable years ending before January 1, 1987, (ii) the Company is organized in conformity with the requirements for qualification as a REIT under the Code, and its current method of operation and ownership will enable it to meet the requirements for qualification as a REIT for the current (2023) taxable year and for future taxable years, and (iii) the discussions in (x) the Base Prospectus under the caption “Material Federal Income Tax Considerations,” (y) the Prospectus Supplement under the caption “Additional Material Federal Income Tax Considerations,” and (z) the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 under the captions “Risk Factors–Failure to qualify as a REIT for federal income tax purposes would cause the Parent Company to be taxed as a corporation, which would substantially reduce funds available for payment of distributions,” “Risk Factors–We may be required to incur additional debt to qualify as a REIT,” “Risk Factors–To maintain our status as a REIT, we limit the amount of shares any one shareholder of the Parent Company can own,” and “Risk Factors–Legislative, administrative, regulatory or other actions affecting REITs, including positions taken by the IRS, could have a material adverse effect on us and our investors,” which are incorporated by reference into the Registration Statement, to the extent that they discuss matters of law or legal conclusions or purport to describe certain provisions of the federal tax laws, are correct summaries of the matters discussed therein.

The opinions set forth in this letter are based on existing law as contained in the Code, Treasury Regulations (including any Temporary and Proposed Regulations), and

interpretations of the foregoing by the Internal Revenue Service and by the courts in effect (or, in case of certain Proposed Regulations, proposed) as of the date hereof, all of which are subject to change, both retroactively or prospectively, and to possibly different interpretations. Moreover, the Company’s ability to achieve and maintain qualification as a REIT depends upon its ability to achieve and maintain certain diversity of stock ownership requirements and, through actual annual operating results, certain requirements under the Code regarding its income, assets and distribution levels. No assurance can be given as to whether, for any given taxable year, the actual ownership of the Company’s stock and its actual operating results and distributions satisfy the tests necessary to achieve and maintain its status as a REIT.

The foregoing opinions are limited to the specific matters covered thereby and should not be interpreted to imply the undersigned has offered its opinion on any other matter. We assume no obligation to update the opinions set forth in this letter after the date hereof.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. The giving of this consent, however, does not constitute an admission that we are “experts” within the meaning of Section 11 of the Securities Act of 1933, as amended (the “Act”), or within the category of persons whose consent is required by Section 7 of the Act.
