The Board of Trustees of EOP and the Board of Directors of Beacon deem it advisable and in the best interests of their respective shareholders, upon the terms and subject to the conditions contained herein, that Beacon shall merge with and into EOP (the "Merger"). B. Upon the terms and subject to the conditions set forth herein, EOP and Beacon shall execute Articles of Merger (the "Articles of Merger") in substantially the form attached hereto as Exhibit A and shall file such Articles of Merger in accordance with Maryland law to effectuate the Merger. C. EOP, as the managing general partner of EOP Partnership, and Beacon, as the sole general partner of Beacon Partnership, deem it advisable and in the best interests of their respective limited partners, subject to the conditions and other provisions contained herein, that Beacon Partnership shall merge with and into EOP Partnership (or a limited liability company owned entirely, directly and/or indirectly, by EOP Partnership, or a limited partnership owned entirely, directly and/or indirectly, by EOP Partnership, as determined by EOP and EOP Partnership), with the holders of partnership interests in Beacon Partnership receiving in any event units of limited partnership interest in EOP Partnership, as set forth herein (the "Partnership Merger" and, together with the Merger, the "Mergers"). D. Upon the terms and subject to the conditions set forth herein, EOP Partnership and Beacon Partnership shall execute a Certificate of Merger (the "Certificate of Merger") in substantially the form attached hereto as Exhibit B and shall file such Certificate of Merger in accordance with Delaware law to effectuate the Partnership Merger. E. For federal income tax purposes, it is intended that the Merger shall qualify as a tax-free reorganization under Section 368 of the Internal Revenue Code of 1986, as amended (the "Code"), and that this Agreement shall constitute a plan of reorganization under Section 368 of the Code. F. For federal income taxes, it is intended that the Partnership Merger, regardless of form, be treated as a contribution by Beacon Partnership of all of its 10 assets to EOP Partnership in exchange for partnership interests in EOP Partnership, as provided for herein, under Section 721 of the Code, and a distribution of such partnership interests by Beacon Partnership to its partners under Section 731 of the Code. G. EOP and Beacon have each received a fairness opinion relating to the transactions contemplated hereby as more fully described herein. H. EOP, EOP Partnership, Beacon and Beacon Partnership desire to make certain representations, warranties and agreements in connection with the Mergers. I.

("EOP Management Corp.") or its assigns. J.

(c) Exchange Procedure. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding Beacon Common Shares and Beacon Preferred Shares (the "Certificates") whose shares were converted into the right to receive the Merger Consideration pursuant to Section 1.10 (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in a form and have such other provisions as EOP may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by EOP, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration into which the Beacon Common Shares or Beacon Preferred Shares, as applicable, theretofore represented by such Certificate shall have been converted pursuant to Section 1.10, as well as any dividends or other distributions to which such holder is entitled pursuant to Section 1.14(d), and the Certificate so surrendered shall forthwith be canceled.

Until surrendered as contemplated by this Section 1.14, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration, without interest, into which the Beacon Common Shares or Beacon Preferred Shares, as applicable, theretofore represented by such Certificate shall have been converted pursuant to Section 1.10, and any dividends or other distributions to which such holder is entitled pursuant to Section 1.14(d). No interest will be paid or will accrue on the Merger Consideration upon the surrender of any Certificate or on any cash payable pursuant to Section 1.14(d) or Section 1.14(g). -7- 16 (d) Record Dates for Final Dividends; Distributions with Respect to Unexchanged Shares. (i) To the extent necessary to satisfy the requirements of Section 857(a)(1) of the Code for the taxable year of Beacon ending at the Effective Time (and avoid the payment of tax with respect to undistributed income), Beacon shall declare a dividend (the "Final Company Dividend") to holders of Beacon Common Shares, the record date for which shall be the close of business on the last business day prior to the Effective Time, in an amount equal to the minimum dividend sufficient to permit Beacon to satisfy such requirements. If Beacon determines it necessary to declare the Final Company Dividend, it shall notify EOP at least ten (10) days prior to the date for the Beacon Shareholders Meeting (as defined in Section 5.1), and EOP shall declare a dividend per share to holders of EOP Common Shares, the record date for which shall be the close of business on the last business day prior to the Effective Time, in an amount per EOP Common Share equal to the quotient obtained by dividing (x) the Final Company Dividend per Beacon Common Share paid by Beacon by (y) the Exchange Ratio. The dividends payable hereunder to holders of Beacon Common Shares shall be paid upon presentation of the certificates of Beacon Common Shares for exchange in accordance with this Section 1.14. (ii) No dividends or other distributions with respect to EOP Common Shares with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of EOP Common Shares represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 1.14(g), in each case until the surrender of such Certificate in accordance with this Section 1.14.

(e) No Further Ownership Rights in Beacon Common Shares and Beacon Preferred Shares. All Merger Consideration paid upon the surrender of Certificates in accordance with the terms of this Section 1.14 (and any cash paid pursuant to Section 1.14(g)) shall be deemed to have been paid in full satisfaction of all rights pertaining to the Beacon Common Shares or Beacon Preferred Shares, as -8- 17 applicable, theretofore represented by such Certificates; provided, however, that Beacon shall transfer to the Exchange Agent cash sufficient to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or made by Beacon on such Beacon Common Shares or Beacon Preferred Shares, as applicable, in accordance with the terms of this Agreement or prior to the date of this Agreement and which remain unpaid at the Effective Time and have not been paid prior to such surrender, and there shall be no further registration of transfers on the stock transfer books of Beacon of the Beacon Common Shares and Beacon Preferred Shares which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to EOP for any reason, they shall be canceled and exchanged as provided in this Section 1.14. (f) No Liability. None of Beacon, EOP or the Exchange Agent shall be liable to any person in respect of any Merger Consideration or dividends delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. Any portion of the Exchange Fund delivered to the Exchange Agent pursuant to this Agreement that remains unclaimed for twelve (12) months after the Effective Time shall be redelivered by the Exchange Agent to EOP, upon demand, and any holders of Certificates who have not theretofore complied with Section 1.14(c) shall thereafter look only to EOP for delivery of the Merger Consideration and any unpaid dividends, subject to applicable escheat and other similar laws. (g) No Fractional Shares (i) No certificates or scrip representing fractional EOP Common Shares shall be issued upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote, to receive dividends or to any other rights of a shareholder of EOP. (ii) No fractional EOP Common Shares shall be issued pursuant to this Agreement. In lieu of the issuance of any fractional EOP Common Shares pursuant to this Agreement, each holder of Beacon Common Shares upon surrender of a Certificate for exchange shall be paid an amount in cash (without interest), rounded to the nearest cent, determined by multiplying (i) the average closing price of one EOP Common Share on the New York Stock Exchange (the "NYSE") on the five trading days immediately preceding the Closing Date (the "Fair Market Value") by (ii) the fractional amount of the EOP Common Shares which such holder would otherwise be entitled to receive under this Section 1.14. (h) Except for the provisions relating to the Exchange Agent, certificates and the exchange procedure (which shall not be applicable), all other provisions of this Section 1.14 shall apply to Beacon Partnership, EOP Partnership and the Beacon OP Units with respect to the Partnership Merger. -9- 18 ARTICLE 2 REPRESENTATIONS AND WARRANTIES OF BEACON Except as set forth in the letter of even date herewith signed by the President and Chief Executive Officer or the Executive Vice President and Chief Operating Officer of Beacon and delivered to EOP prior to the execution hereof (the "Beacon Disclosure Letter"), Beacon and Beacon Partnership represent and warrant to EOP and EOP Partnership as follows: 2.1 Organization, Standing and Power of Beacon.

Except as disclosed in the Beacon SEC Documents, (a) none of Beacon, any of the Beacon Subsidiaries or, to Beacon's Knowledge, any other Person has caused or permitted the unlawful presence of any hazardous substances, hazardous materials, toxic substances or waste materials (collectively, "Hazardous Materials") on or under any of the Beacon Properties and none of Beacon nor any of the Beacon Subsidiaries has any knowledge of the presence of any Hazardous Materials on or under any of the Beacon Properties or (b) none of Beacon, any of the Beacon Subsidiaries, or to Beacon's Knowledge, any other Person, has caused or permitted any unlawful spills, releases, discharges or disposal of Hazardous Materials to have occurred or be presently occurring on or from the Beacon Properties as a result of any construction on or operation and use of such properties and none of Beacon nor any of the Beacon Subsidiaries has any knowledge of any spills, releases, discharges or disposal of Hazardous Materials to have occurred or be presently occurring on, under or from the Beacon Properties as a result of any construction on or operation and use of such properties, in each of the foregoing cases, which presence or occurrence would, individually or in the aggregate, have a Beacon Material Adverse Effect; and in connection with the construction on or operation and use of the Beacon Properties, Beacon and the Beacon Subsidiaries have not failed to comply in any material respect 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, except to the extent such failure to comply, individually or in the aggregate, would not have a Beacon Material Adverse Effect. Beacon has previously delivered or made available to EOP complete copies of all final versions of environmental investigations and testing or analysis made by or on behalf of Beacon or any of the Beacon Subsidiaries that are in the possession of any of them with respect to the environmental condition of the Beacon Properties. 2.11 Related Party Transactions.

Such documents, copies of all of which have previously been delivered -20- 29 or made available to EOP, are listed in Schedule 2.11 to the Beacon Disclosure Letter. As used in this Agreement, the term "Affiliate" shall have the same meaning as such term is defined in Rule 405 promulgated under the Securities Act. 2.12 Employee Benefits. As used herein, the term "Employee Plan" includes any pension, retirement, savings, disability, medical, dental, health, life, death benefit, group insurance, profit sharing, deferred compensation, stock option, bonus, incentive, vacation pay, tuition reimbursement, severance pay, or other employee benefit plan, trust, agreement, contract, agreement, policy or commitment (including, without limitation, any pension plan, as defined in Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended, and the rules and regulations promulgated thereunder ("ERISA") ("Pension Plan"), and any welfare plan as defined in Section 3(1) of ERISA ("Welfare Plan")), whether any of the foregoing is funded, insured or self-funded, written or oral, (i) sponsored or maintained by Beacon or its Subsidiaries (each a "Controlled Group Member") and covering any Controlled Group Member's active or former employees (or their beneficiaries), (ii) to which any Controlled Group Member is a party or by which any Controlled Group Member (or any of the rights, properties or assets thereof) is bound or (iii) with respect to which any current Controlled Group Member may otherwise have any material liability (whether or not such Controlled Group Member still maintains such Employee Plan). Each Employee Plan is listed on Schedule 2.12 to the Beacon Disclosure Letter. With respect to the Employee Plans: (a) Except as proposed in Schedule 2.12(a) to the Beacon Disclosure Letter, no Controlled Group Member has any continuing liability under any Welfare Plan which provides for continuing benefits or coverage for any participant or any beneficiary of a participant after such participant's termination of employment, except as may be required by Section 4980B of the Code or Section 601 (et seq.) of ERISA, or under any applicable state law, and at the expense of the participant or the beneficiary of the participant. (b) Each Employee Plan complies in all material respects with the applicable requirements of ERISA and any other applicable law governing such Employee Plan, and, to the best Knowledge of Beacon, each Employee Plan has at all times been properly administered in all material respects in accordance with all such requirements of law, and in accordance with its terms and the terms of any applicable collective bargaining agreement to the extent consistent with all such requirements of law. Each Pension Plan which is intended to be qualified is qualified under Section 401(a) of the Code, has received a favorable determination letter from the IRS stating that such Plan meets the requirements of Section 401(a) of the Code and that the trust associated with such Plan is tax-exempt under Section 501(a) of the Code and, to the best Knowledge of Beacon, no event has occurred which would jeopardize the qualified status of any such plan or the tax exempt status of any such trust under Sections 401(a) and Section 501(a) of the -21- 30 Code, respectively. No lawsuits, claims (other than routine claims for benefits) or complaints to, or by, any person or governmental entity have been filed, are pending, to the best Knowledge of Beacon, threatened with respect to any Employee Plan and, to the best Knowledge of Beacon, there is no fact or contemplated event which would be expected to give rise to any such lawsuit, claim (other than routine claims for benefits) or complaint with respect to any Pension Plan. Without limiting the foregoing, the following are true with respect to each Employee Plan: (i) all Controlled Group Members have complied in all material respects with the reporting and disclosure requirements of ERISA, the Code, or both, with respect to each Employee Plan and no Controlled Group Member has incurred any material liability in connection with such reporting or disclosure; (ii) all contributions and payments with respect to Employee Plans that are required to be made by a Controlled Group Member with respect to periods ending on or before the Closing Date (including periods from the first day of the current plan or policy year to the Closing Date) have been, or will be, made or accrued before the Closing Date in accordance with the appropriate plan document, actuarial report, collective bargaining agreements or insurance contracts or arrangements or as otherwise required by ERISA or the Code; and (iii) with respect to each such Employee Plan, to the extent applicable, Beacon has delivered to or has made available to EOP true and complete copies of (A) plan documents, or any and all other documents that establish the existence of the plan, trust, arrangement, contract, policy or commitment and all amendments thereto, (B) the most recent determination letter, if any, received from the IRS, (C) the three most recent Form 5500 Annual Reports (and all schedules and reports relating thereto) and actuarial reports and (D) all related trust agreements, insurance contract or other funding agreements that implement each such Employee Plan. (c) With respect to each Employee Plan, to the best Knowledge of Beacon, there has not occurred, and no person or entity is contractually bound to enter into, any "prohibited transaction" within the meaning of Section 4975(c) of the Code or Section 406 of ERISA, which transaction is not exempt under Section 4975(d) of the Code or Section 408 of ERISA and which could subject Beacon or any Controlled Group Member to material liability. (d) Except as disclosed in Schedule 2.12(d) to the Beacon Disclosure Letter, no Controlled Group Member has maintained or been obligated to contribute to any Employee Plan subject to Code Section 412 or Title IV of -22- 31 ERISA. No Employee Plan subject to Code Section 412 or Title IV of ERISA has been terminated. (e) With respect to each pension plan maintained by any Controlled Group Member, such Plans provide the Plan Sponsor the authority to amend or terminate the Plan at any time, subject to applicable requirements of ERISA and the Code. 2.13 Employee Policies. No employee handbook of Beacon or any of the Beacon Subsidiaries is currently in effect. Schedule 2.13 to the Beacon Disclosure Letter fairly and accurately summarizes all material employee policies, vacation policies and payroll policies. 2.14 Taxes. (a) Each of Beacon and the Beacon Subsidiaries (A) has filed all Tax returns and reports required to be filed by it (after giving effect to any filing extension properly granted by a Governmental Entity having authority to do so) and all such returns and reports are accurate and complete in all material respects, and (B) has paid (or Beacon has paid on its behalf) all Taxes (as defined below) shown on such returns and reports as required to be paid by it, except those where the failure to file such tax returns and reports or pay such Taxes would not have a Beacon Material Adverse Effect. The most recent audited financial statements contained in the Beacon SEC Documents reflect an adequate reserve for all material Taxes payable by Beacon and the Beacon Subsidiaries for all taxable periods and portions thereof through the date of such financial statements. Since the Beacon Financial Statement Date, Beacon has incurred no liability for taxes under Sections 857(b), 860(c) or 4981 of the Code, including without limitation any tax arising from a prohibited transaction described in Section 857(b)(6) of the Code, and neither Beacon nor any Beacon Subsidiary has incurred any material liability for taxes other than in the ordinary course of business. No event has occurred, and no condition or circumstance exists, which presents a material risk that any material Tax described in the preceding sentence will be imposed upon Beacon. To the Knowledge of Beacon, no deficiencies for any Taxes have been proposed, asserted or assessed against Beacon or any of the Beacon Subsidiaries, and no requests for waivers of the time to assess any such Taxes are pending. As used in this Agreement, "Taxes" shall include all federal, state, local and foreign income, property, sales, franchise, employment, excise and other taxes, tariffs or governmental charges of any nature whatsoever, together with penalties, interest or additions to Tax with respect thereto. (b) Beacon and BeaMetFed, Inc. ("BeaMet") (i) for all taxable years commencing with 1994 (or, in the case of BeaMet, 1995) through December 31, 1996 has been subject to taxation as a real estate investment trust (a "REIT") within the meaning of Section 856 of the Code and has satisfied all requirements to -23- 32 qualify as a REIT for such years, (ii) has operated since December 31, 1996 to the date of this representation, and intends to continue to operate, in such a manner as to qualify as a REIT for the taxable year ending December 31, 1997 and for the taxable year of Beacon ending on the Closing Date (or, in the case of BeaMet, on December 31, 1998), and (iii) has not taken or omitted to take any action which would reasonably be expected to result in a challenge to its status as a REIT and, to Beacon's Knowledge, no such challenge is pending or threatened. Each Beacon Subsidiary which is a partnership, joint venture or limited liability company (i) has been since its formation and continues to be treated for federal income tax purposes as a partnership and not as a corporation or an association taxable as a corporation and (ii) has not since the later of its formation or the acquisition by Beacon of a direct or indirect interest therein, owned any assets (including, without limitation, securities) that would cause Beacon to violate Section 856(c)(5) of the Code. No Beacon Subsidiary (other than BeaMet, the Management Company, the Design Company and the Construction Company) is a corporation (or an entity that would, under applicable federal income tax principles, be classified as an association taxable as a corporation). Beacon Partnership is not a publicly traded partnership within the meaning of Section 7704 of the Code. Neither Beacon nor any Beacon Subsidiary holds any asset (x) the disposition of which would be subject to rules similar to Section 1374 of the Code as a result of a notice under IRS Notice 88-19 or (y) which is subject to a consent filed pursuant to Section 341(f) of the Code and the regulations thereunder. 2.15 No Payments to Employees, Officers or Directors. Schedule 2.15 to the Beacon Disclosure Letter contains a true and complete list of all arrangements, agreements or plans pursuant to which cash and non-cash payments which will become payable (and the maximum aggregate amount which may be payable thereunder) to each employee, officer or director of Beacon or any Beacon Subsidiary as a result of the Merger or a termination of service subsequent to the consummation of the Merger. Except as described in Schedule 2.15 to the Beacon Disclosure Letter, or as otherwise provided for in this Agreement, there is no employment or severance contract, or other agreement requiring payments, cancellation of indebtedness or other obligation to be made on a change of control or otherwise as a result of the consummation of any of the transactions contemplated by this Agreement or as a result of a termination of service subsequent to the consummation of any of the transactions contemplated by this Agreement, with respect to any employee, officer or director of Beacon or any Beacon Subsidiary. 2.16 Broker; Schedule of Fees and Expenses. No broker, investment banker, financial advisor or other person, other than Morgan Stanley & Co., Incorporated, the fees and expenses of which are described in the engagement letter dated September 12, 1997, between Morgan Stanley & Co., Incorporated and Beacon, a true, correct and complete copy of which has previously been given to EOP, is entitled to any broker's, finder's, financial advisor's or other similar fee or -24- 33 commission in connection with the transactions contemplated hereby based upon arrangements made by or on behalf of Beacon or any Beacon Subsidiary. 2.17 Compliance with Laws.

(a) Neither Beacon nor any Beacon Subsidiary has received a written notice that Beacon or any Beacon Subsidiary is in violation of or in default under (nor to the Knowledge of Beacon does there exist any condition which upon the passage of time or the giving of notice or both would cause such a violation of or default under) any material loan or credit agreement, note, bond, mortgage, indenture, lease, permit, concession, franchise, license or any other material contract, agreement, arrangement or understanding, to which it is a party or by which it or any of its properties or assets is bound, nor to the Knowledge of Beacon does such a violation or default exist, except to the extent that such violation or default, individually or in the aggregate, would not have a Beacon Material Adverse Effect. (b) Except for any of the following expressly identified in Beacon SEC Documents, Schedule 2.18(b) to the Beacon Disclosure Letter sets forth a list of each material loan or credit agreement, note, bond, mortgage, indenture and any other agreement or instrument pursuant to which any Indebtedness (as defined below) of Beacon or any of the Beacon Subsidiaries, other than Indebtedness payable to Beacon or a Beacon Subsidiary is outstanding or may be incurred. For purposes of this Section 2.18, "Indebtedness" shall mean (i) indebtedness for borrowed money, whether secured or unsecured, (ii) obligations under conditional sale or other title retention agreements relating to property purchased by such person, (iii) capitalized lease obligations, (iv) obligations under interest rate cap, swap, collar or similar transaction or currency hedging transactions (valued at the termination value thereof) and (v) guarantees of any such indebtedness of any other person. (c) To the extent not set forth in response to the requirements of Section 2.18(b), Schedule 2.18(c) to the Beacon Disclosure Letter sets forth each interest rate cap, interest rate collar, interest rate swap, currency hedging transaction, and any other agreement relating to a similar transaction to which Beacon or any Beacon Subsidiary is a party or an obligor with respect thereto. -25- 34 (d) Except as set forth in Schedule 2.18(d) of the Beacon Disclosure Letter, neither Beacon nor any of the Beacon Subsidiaries is a party to any agreement which would restrict any of them from prepaying any of their Indebtedness without penalty or premium at any time or which requires any of them to maintain any amount of Indebtedness with respect to any of the Beacon Properties.

(g) Beacon has delivered to EOP prior to the date of this Agreement a true and complete capital budget relating to budgeted construction. Schedule 2.18(g) to the Beacon Disclosure Letter lists all material agreements entered into by Beacon or any of the Beacon Subsidiaries relating to the development or construction of, or additions or expansions to, any Beacon Real Properties (or any properties with respect to which Beacon has executed as of the date of this Agreement a purchase agreement or other similar agreement) which are currently in effect and under which Beacon or any of the Beacon Subsidiaries currently has, or expects to incur, an obligation in excess of $250,000. True, correct and complete copies of such agreements have previously been delivered or made available to EOP. (h) Schedule 2.18(h) to the Beacon Disclosure Letter lists all agreements entered into by Beacon or any Beacon Subsidiary providing for the sale of, or option to sell, any Beacon Properties or the purchase of, or option to purchase, by Beacon or any Beacon Subsidiary, on the one hand, or the other party thereto, on the other hand, any real estate which are currently in effect. (i) Except as set forth in Schedule 2.18(i) to the Beacon Disclosure Letter, neither Beacon nor any Beacon Subsidiary has any material continuing contractual liability (A) for indemnification or otherwise under any agreement relating to the sale of real estate previously owned, whether directly or indirectly, by Beacon or any Beacon Subsidiary or (B) to pay any additional purchase price for any of the Beacon Properties.

EOP and EOP Operating Partnership have filed all required reports, schedules, forms, statements and other documents with the SEC since July 8, 1997 through the date hereof (the "EOP SEC Documents"). Schedule 3.6(a) to the EOP Disclosure Letter contains a complete list of all EOP SEC Documents filed by EOP under the Exchange Act since July 8, 1997 and on or prior to the date of this Agreement. All of the EOP SEC Documents (other than preliminary material), as of their respective filing dates, complied in all material respects with all applicable requirements of the Securities Act and the Exchange Act and, in each case, the rules and regulations promulgated thereunder applicable to such EOP SEC Documents. None of the EOP SEC Documents at the time of filing contained any untrue statement of -32- 41 a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except to the extent such statements have been modified or superseded by later EOP SEC Documents filed and publicly available prior to the date of this Agreement.

Except for liabilities and obligations set forth in the EOP SEC Documents or in Schedule 3.6(b) to the EOP Disclosure Letter, neither EOP nor any EOP Subsidiary has any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise) required by GAAP to be set forth on a consolidated balance sheet of EOP or in the notes thereto and which, individually or in the aggregate, would have an EOP Material Adverse Effect. 3.7 Absence of Certain Changes or Events. Except as disclosed in the EOP SEC Documents or in Schedule 3.7 to the EOP Disclosure Letter, since the date of the most recent audited financial statements included in the EOP SEC Documents (the "EOP Financial Statement Date"), EOP and the EOP Subsidiaries have conducted their business only in the ordinary course (taking into account prior practices, including the acquisition of properties and issuance of securities) and there has not been (a) any material adverse change in the business, financial condition or results of operations of EOP and the EOP Subsidiaries taken as a whole (a "EOP Material Adverse Change"), nor has there been any occurrence or circumstance that with the passage of time would reasonably be expected to result in an EOP Material Adverse Change, (b) except for regular quarterly distributions (in the case of EOP) not in excess of $.30 per EOP Common Share, subject to rounding adjustments as necessary and with customary record and payment dates, any authorization, declaration, setting aside or payment of any dividend or other distribution (whether in cash, stock or property) with respect to any of EOP's shares of beneficial interest, (c) any split, combination or reclassification of any of EOP's shares of beneficial interest, (d) any damage, destruction or loss, whether or not covered by insurance, that has or would have an EOP Material Adverse Effect or (e) any change made prior to the date of this Agreement in accounting methods, principles or practices by EOP or any EOP Subsidiary materially affecting its -33- 42 assets, liabilities or business, except insofar as may have been disclosed in the EOP SEC Documents or required by a change in GAAP. 3.8 Litigation. Except as disclosed in the EOP SEC Documents or in Schedule 3.8 to the EOP Disclosure Letter, and other than personal injury and other routine tort litigation arising from the ordinary course of operations of EOP and the EOP Subsidiaries (a) which are covered by adequate insurance or (b) for which all material costs and liabilities arising therefrom are reimbursable pursuant to common area maintenance or similar agreements, there is no suit, action or proceeding pending (in which service of process has been received by an employee of EOP or an EOP Subsidiary) or, to the Knowledge of EOP (as defined in Section 3.19), threatened in writing against or affecting EOP or any EOP Subsidiary that, individually or in the aggregate, could reasonably be expected to (i) have an EOP Material Adverse Effect or (ii) prevent the consummation of any of the transactions contemplated by this Agreement, nor is there any judgment, decree, injunction, rule or order of any Governmental Entity or arbitrator outstanding against EOP or any EOP Subsidiary having, or which, insofar as reasonably can be foreseen, in the future would have, any such effect. 3.9 Properties. (a) Except as set forth in Schedule 3.9(a) to the EOP Disclosure Letter, EOP or one of the EOP Subsidiaries owns fee simple title to each of the real properties listed in the EOP SEC Filings as owned by it (the "EOP Properties"), except where the failure to own such title would not have an EOP Material Adverse Effect. (b) The EOP Properties are not subject to any Encumbrances or Property Restrictions which reasonably could be expected to cause an EOP Material Adverse Effect. (c) Valid policies of title insurance have been issued insuring EOP's or the applicable EOP Subsidiary's fee simple title or leasehold estate, as the case may be, to the EOP Properties in amounts which are, except in the case of San Felipe Plaza, at least equal to the purchase price thereof paid by EOP or the applicable EOP Subsidiaries therefor, except where the failure to obtain such title insurance would not have an EOP Material Adverse Effect. (d) EOP has no Knowledge (i) that it has failed to obtain a certificate, permit or license from any governmental authority having jurisdiction over any of the EOP Properties where such failure would have an EOP Material Adverse Effect or of any pending threat of modification or cancellation of any of the same which would have an EOP Material Adverse Effect, (ii) of any written notice of any violation of any federal, state or municipal law, ordinance, order, rule, regulation or requirement affecting any of the EOP Properties issued by any -34- 43 governmental authorities which would have an EOP Material Adverse Effect or (iii) of any structural defects relating to EOP Properties, EOP Properties whose building systems are not in working order, physical damage to any EOP Property for which there is no insurance in effect covering the cost of restoration, any current renovation or uninsured restoration, except such structural defects, building systems not in working order, physical damage, renovation and restoration which, in the aggregate, would not have an EOP Material Adverse Effect. (e) Except as set forth in Schedule 3.9(e) to the EOP Disclosure Letter, neither EOP nor any of the EOP Subsidiaries has received any written or published notice to the effect that (i) any condemnation or rezoning proceedings are pending or threatened with respect to any of the EOP Properties or (ii) any zoning, building or similar law, code, ordinance, order or regulation is or will be violated by the continued maintenance, operation or use of any buildings or other improvements on any of the EOP Properties or by the continued maintenance, operation or use of the parking areas, other than such notices which, in the aggregate, would not have an EOP Material Adverse Effect. (f) All work to be performed, payments to be made and actions to be taken by EOP or the EOP Subsidiaries prior to the date hereof pursuant to any agreement entered into with a governmental body or authority in connection with a site approval, zoning reclassification or similar action relating to any EOP Properties (e.g., Local Improvement District, Road Improvement District, Environmental Mitigation), has been performed, paid or taken, as the case may be, except where the failure to do so would, in the aggregate, not have an EOP Material Adverse Effect, and EOP has no Knowledge of any planned or proposed work, payments or actions that may be required after the date hereof pursuant to such agreements. (g) The rent roll previously provided by EOP to Beacon (the "EOP Rent Roll") lists each EOP Space Lease (as defined below) in effect as of the respective dates in August 1997 indicated in the EOP Rent Roll. "EOP Space Lease" means each lease or other right of occupancy affecting or relating to a property in which EOP Partnership (or an entity in which it directly or indirectly has an interest) is the landlord, either pursuant to the terms of the lease agreement or as successor to any prior landlord, but excluding any ground lease. EOP has made available to Beacon true, correct and complete copies of all EOP Space Leases, including all amendments, modifications, supplements, renewals, extensions and guarantees related thereto, as of the date hereof. Except for discrepancies that, either individually or in the aggregate, would not reasonably be expected to have an EOP Material Adverse Effect, all information set forth in the EOP Rent Roll is true, correct, and complete as of the date thereof. Except as set forth in a delinquency report made available to EOP, neither EOP nor any EOP Subsidiary, on the one hand, nor, to the Knowledge of EOP or EOP Partnership, any other party, on the other hand, is in monetary -35- 44 default under any EOP Space Lease, except for such defaults that would not reasonably be expected to have a Material Adverse Effect. 3.10 Environmental Matters. Except as disclosed in the EOP SEC Documents or on Schedule 3.10 to the EOP Disclosure Letter, (a) none of EOP, any of the EOP Subsidiaries or, to EOP's Knowledge, any other Person has caused or permitted the unlawful presence of any Hazardous Materials on or under any of the EOP Properties or (b) any unlawful spills, releases, discharges or disposal of Hazardous Materials to have occurred or be presently occurring on, under or from the EOP Properties as a result of any construction on or operation and use of such properties, which presence or occurrence would, individually or in the aggregate, have an EOP Material Adverse Effect; and in connection with the construction on or operation and use of the EOP Properties, EOP and the EOP Subsidiaries have not failed to comply in any material respect 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, except to the extent such failure to comply, individually or in the aggregate, would not have an EOP Material Adverse Effect. 3.11 Taxes. (a) Each of EOP and the EOP Subsidiaries (i) has filed all Tax returns and reports required to be filed by it (after giving effect to any filing extension properly granted by a Governmental Entity having authority to do so), and all such returns and reports are accurate and complete in all material respects, and (ii) has paid (or EOP has paid on its behalf) all Taxes shown on such returns and reports as required to be paid by it except where the failure to file such tax returns or reports and failure to pay such Taxes would not have an EOP Material Adverse Effect. The most recent audited financial statements contained in the EOP SEC Documents reflect an adequate reserve for all material Taxes payable by EOP and the EOP Subsidiaries for all taxable periods and portions thereof through the date of such financial statements. Since the EOP Financial Statement Date, EOP has incurred no liability for taxes under Sections 857(b), 860(c) or 4981 of the Code, including without limitation any tax arising from a prohibited transaction described in Section 857(b)(6) of the Code, and neither EOP nor any EOP Subsidiary has incurred any material liability for taxes other than in the ordinary course of business. No event has occurred, and no condition or circumstance exists, which presents a material risk that any material Tax described in the preceding sentence will be imposed upon EOP. To the Knowledge of EOP, no deficiencies for any Taxes have been proposed, asserted or assessed against EOP or any of the EOP Subsidiaries, and no requests for waivers of the time to assess any such Taxes are pending. (b) EOP (i) has operated, and intends to continue to operate, in such a manner as to qualify as a REIT within the meaning of Section 856 of the -36- 45 Code for the taxable year ending December 31, 1997 and intends to continue to operate in such a manner as to qualify as a REIT for the taxable year that includes the Closing Date and (ii) has not taken or omitted to take any action which would reasonably be expected to result in a challenge to its status as a REIT, and to EOP's Knowledge, no such challenge is pending or threatened. Each EOP Subsidiary which is a partnership, joint venture or limited liability company (i) has been treated since its formation and continues to be treated for federal income tax purposes as a partnership and not as a corporation or as an association taxable as a corporation and (ii) has not since the later of its formation or the acquisition by EOP of a direct or indirect interest therein, owned any assets (including, without limitation, securities) that would cause EOP to violate Section 856(c)(5) of the Code. Each EOP Subsidiary which is a corporation (other than EOP Management Corp.) has been since its formation a qualified REIT subsidiary under Section 856(i) of the Code. EOP Partnership is not a publicly traded partnership within the meaning of Section 7704 of the Code. Except as set forth in Schedule 3.11 to the EOP Disclosure Letter neither EOP nor any EOP Subsidiary holds any asset (x) the disposition of which would be subject to rules similar to Section 1374 of the Code as a result of a notice under IRS Notice 88-19 or (y) which is subject to a consent filed pursuant to Section 341(f) of the Code and the regulations thereunder. 3.12 Brokers; Schedule of Fees and Expenses. No broker, investment banker, financial advisor or other person, other than J.P. Morgan Securities Inc. and Merrill Lynch & Co., the fees and expenses of which will be paid by EOP and are described in the respective engagement letters with J.P. Morgan Securities Inc. and Merrill Lynch & Co., true, correct and complete copies of which have previously been given to Beacon, is entitled to any broker's, finder's, financial advisor's or other similar fee or commission in connection with the transactions contemplated hereby based upon arrangements made by or on behalf of EOP or any EOP Subsidiary. 3.13 Compliance with Laws. Neither EOP nor any of the EOP Subsidiaries has violated or failed to comply with any statute, law, ordinance, regulation, rule, judgment, decree or order of any Governmental Entity applicable to its business, properties or operations, except to the extent that such violation or failure would not have an EOP Material Adverse Effect. 3.14 Contracts; Debt Instruments. Neither EOP nor any EOP Subsidiary has received a written notice that EOP or any EOP Subsidiary is in violation of or in default under (nor to the Knowledge of EOP does there exist any condition which upon the passage of time or the giving of notice or both would cause such a violation of or default under) any material loan or credit agreement, note, bond, mortgage, indenture, lease, permit, concession, franchise, license or any other material contract, agreement, arrangement or understanding, to which it is a party or by which it or any of its properties or assets is bound, nor to the Knowledge of EOP does such a violation or default exist, except to the extent such violation or -37- 46 default, individually or in the aggregate, would not have an EOP Material Adverse Effect, except as set forth in the EOP SEC Documents or in Schedule 3.14 to the EOP Disclosure Letter. 3.15 Opinion of Financial Advisor. EOP has received the oral opinion of J.P. Morgan Securities Inc., satisfactory to EOP, to the effect that the consideration to be paid by EOP and EOP Partnership in connection with the Mergers is fair, from a financial point of view, to EOP and EOP Operating Partnership. 3.16 State Takeover Statutes. EOP has taken all action necessary to exempt transactions between EOP and Beacon and its Affiliates from the operation of Takeover Statutes. 3.17 Investment Company Act of 1940. Neither EOP nor any of the EOP Subsidiaries is, or at the Effective Time will be, required to be registered under the 1940 Act. 3.18 Definition of Knowledge of EOP. As used in this Agreement, the phrase "Knowledge of EOP" (or words of similar import) means the knowledge of those individuals identified in Schedule 3.19 to the EOP Disclosure Letter. 3.19 EOP Not an Interested Stockholder. EOP is not an "interested stockholder" of Beacon or an "affiliate of an interested stockholder" of Beacon within the meaning of Section 3-601 of the MGCL.

Prior to the Effective Time, Beacon agrees, for itself and in its capacity as general partner of the Beacon Partnership, that: (a) neither it nor any of the Beacon Subsidiaries shall invite, initiate, solicit or encourage, directly or indirectly, any inquiries, proposals, discussions or negotiations or the making or implementation of any proposal or offer (including, without limitation, any proposal or offer to its shareholders) with respect to a merger, acquisition, tender offer, exchange offer, transaction resulting in the issuance of securities representing 10% or more of the outstanding equity securities of Beacon, consolidation, share exchange, business combination, sale, lease, exchange, mortgage, pledge, transfer or other disposition of 10% or more of the assets or equity securities (including, without limitation, partnership interests and units) of Beacon or Beacon Partnership, other than the transactions contemplated by this Agreement (any such proposal or offer being hereinafter referred to as an "Acquisition Proposal") or engage in any discussions or negotiations concerning or provide any confidential or non-public information or data to, or have any discussions with, any person relating to an Acquisition Proposal, or otherwise facilitate any effort or attempt to make or implement an Acquisition Proposal; (b) neither it nor any of the Beacon Subsidiaries will permit any of its officers, directors, employees, affiliates, agents, investment bankers, financial advisors, attorneys, accountants, brokers, finders or other representative retained by Beacon to engage in any of the activities described in Section 4.3(a); (c) it and the Beacon Subsidiaries will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any of the foregoing and will take the necessary steps to inform the individuals or entities referred to in Section 4.3(b) of the obligations undertaken in this Section 4.3; and -44- 53 (d) it will notify EOP immediately if Beacon or any of the Beacon Subsidiaries receives any such inquiries or proposals, or any requests for such information, or if any such negotiations or discussions are sought to be initiated or continued with it; provided, however, that nothing contained in this Section 4.3 shall prohibit the Board of Directors of Beacon (including with respect to Beacon's capacity as general partner of Beacon Partnership) from (i) furnishing information to or entering into discussions or negotiations with, any person or entity that makes an unsolicited Acquisition Proposal, if, and only to the extent that (A) a majority of the Board of Directors of Beacon determines in good faith, based upon the advice of its outside counsel, that such action is required for the Board of Directors of Beacon to comply with its duties to shareholders imposed by applicable law and (B) prior to furnishing such information to, or entering into discussions or negotiations with, such person or entity, Beacon provides written notice to EOP to the effect that it is furnishing information to, or entering into discussions with, such person or entity; and (ii) making any disclosure required by applicable law with regard to an Acquisition Proposal. Nothing in this Section 4.3 shall (x) permit Beacon to terminate this Agreement (except as specifically provided in Article 7 hereof), (y) permit Beacon to enter into an agreement for an Acquisition Proposal during the term of this Agreement or (z) affect any other obligation of Beacon under this Agreement; provided, however, that a majority of the Board of Directors of Beacon may approve and recommend a Superior Acquisition Proposal and, in connection therewith, withdraw or modify its approval or recommendation of this Agreement and the Merger in accordance with Section 5.1(e). Any disclosure that the Board of Directors of Beacon may be compelled to make with respect to the receipt of an Acquisition Proposal in order to comply with its duties to shareholders imposed by applicable law or Rule 14d-9 or 14e-2 of the Exchange Act will not constitute a violation of this Section 4.3. As used herein, "Superior Acquisition Proposal" means a bona fide Acquisition Proposal made by a third party which a majority of the members of the Board of Directors of Beacon resolves in good faith to be in the best interests of and more favorable to Beacon's shareholders than the Merger and which the Board of Directors of Beacon determines is reasonably capable of being consummated. 4.4 Affiliates. Prior to the Effective Time, Beacon shall cause to be prepared and delivered to EOP a list (reasonably satisfactory to counsel for EOP) identifying all persons who, at the time of the Beacon and EOP Shareholders Meetings, may be deemed to be "affiliates" of Beacon as that term is used in paragraphs (c) and (d) of Rule 145 under the Securities Act (the "Affiliates"). Beacon shall use its reasonable best efforts to cause each person who is identified as an Affiliate in such list to deliver to EOP on or prior to the Effective Time a written agreement, in the form previously approved by the parties hereto, that such Affiliate will not sell, pledge, transfer or otherwise dispose of any EOP Common -45- 54 Shares issued to such Affiliate pursuant to the Merger, except pursuant to an effective registration statement under the Securities Act or in compliance with paragraph (d) of Rule 145 or as otherwise permitted by the Securities Act. EOP shall be entitled to place legends as specified in such written agreements on the certificates representing any EOP Common Shares to be received pursuant to the terms of this Agreement by such Affiliates who have executed such agreements and to issue appropriate stop transfer instructions to the transfer agent for the EOP Common Shares issued to such Affiliates, consistent with the terms of such agreements. The Surviving Trust shall timely file the reports required to be filed by it under the Exchange Act and the rules and regulations adopted by the SEC thereunder, and it will take such further action as any Affiliate of Beacon or EOP may reasonably request, all to the extent required from time to time to enable such Affiliate to sell shares of beneficial interest of the Surviving Trust received by such Affiliate in the Merger without registration under the Securities Act pursuant to (i) Rule 145(d)(1) under the Securities Act, as such rule may be amended from to time, or (ii) any successor rule or regulation hereafter adopted by the SEC. 4.5 Other Actions. Each of Beacon and Beacon Partnership on the one hand and EOP and EOP Partnership on the other hand shall not, and shall use commercially reasonable efforts to cause their respective subsidiaries and joint ventures not to take, any action that would result in (i) any of the representations and warranties of such party (without giving effect to any "knowledge" qualification) set forth in this Agreement that are qualified as to materiality becoming untrue, (ii) any of such representations and warranties (without giving effect to any "knowledge" qualification) that are not so qualified becoming untrue in any material respect or (iii) except as contemplated by Section 4.3, any of the conditions to the Merger set forth in Article 6 not being satisfied. ARTICLE 5 ADDITIONAL COVENANTS 5.1 Preparation of the Registration Statement and the Proxy Statement; Beacon Shareholders Meeting, Beacon Unitholders Consent Solicitation and EOP Shareholders Meeting. (a) As promptly as practicable after execution of this Agreement, (i) each of Beacon and EOP shall prepare and file with the SEC (with appropriate requests for confidential treatment, unless the parties hereto otherwise agree) under the Exchange Act, (x) one or more joint proxy statements/prospectuses and forms of proxies (such joint proxy statement(s)/prospectus(es) together with any amendments to supplements thereto, the "Proxy Statement") relating to the stockholder meetings of each of Beacon and EOP, the vote of the stockholders of Beacon and EOP with respect to the Merger, and the consent, if any, of partners of Beacon Partnership and EOP Partnership in connection with any required Partner -46- 55 Approvals and (y) an information statement/prospectus relating to the issuance of EOP Preferred Shares pursuant to the Merger and (ii) following clearance by the SEC of the Proxy Statement, EOP shall within two business days prepare and file with the SEC under the Securities Act a registration statement on Form S-4 (such registration statement, together with any amendments or supplements thereto, the "Form S-4"), in which the Proxy Statement and any information statement/prospectus described in clause (y) above will be included, as one or more prospectuses in connection with the registration under the Securities Act of the EOP Common Shares, EOP Preferred Shares and EOP OP Units to be distributed to the holders of Beacon Common Shares, Beacon Preferred Stock and Beacon OP Units in the Merger. The respective parties will cause the Proxy Statement and the Form S-4 to comply as to form in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the rules and regulations thereunder. Each of Beacon, Beacon Partnership, EOP and EOP Partnership shall furnish all information about itself and its business and operations and all necessary financial information to the other as the other may reasonably request in connection with the preparation of the Proxy Statement and the Form S-4. EOP shall use its reasonable best efforts, and Beacon will cooperate with it, to have the Form S-4 declared effective by the SEC as promptly as practicable (including clearing the Proxy Statement with the SEC), taking into account EOP's permitted activities hereunder and applicable legal requirements. Each of Beacon and Beacon Partnership, on the one hand, and EOP and EOP Partnership, on the other hand, agree promptly to correct any information provided by it for use in the Proxy Statement and the Form S-4 if and to the extent that such information shall have become false or misleading in any material respect, and each of the parties hereto further agrees to take all steps necessary to amend or supplement the Proxy Statement and the Form S-4 and to cause the Proxy Statement and the Form S-4 as so amended or supplemented to be filed with the SEC and to be disseminated to their respective stockholders and partners, in each case as and to the extent required by applicable federal and state securities laws. Each of Beacon, Beacon Partnership, EOP and EOP Partnership agrees that the information provided by it for inclusion in the Proxy Statement or the Form S-4 and each amendment or supplement thereto, at the time of mailing thereof and at the time of the respective meetings of stockholders of Beacon and EOP and at the time of the respective taking of consents, if any, of partners of Beacon Partnership and EOP Partnership, will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. EOP will advise and deliver copies (if any) to Beacon, promptly after it receives notice thereof, of any request by the SEC for amendment of the Proxy Statement or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information (regardless whether such requests relate to EOP or EOP Partnership, on the one hand, and Beacon or Beacon Partnership, on the other hand), and EOP shall promptly notify Beacon of (i) the time when the Form S-4 has become -47- 56 effective, (ii) or any supplement or amendment thereto has been filed, (iii) the issuance of any stop order, and (iv) the suspension of the qualification and registration of the EOP Common Shares, EOP Preferred Shares and EOP OP Units issuable in connection with the Mergers. (b) Each of Beacon, Beacon Partnership, EOP and EOP Partnership shall use its reasonable best efforts to timely mail the joint proxy statement/prospectus contained in the Form S-4 to its stockholders. It shall be a condition to the mailing of the joint proxy statement/prospectus that (i) EOP and EOP Partnership shall have received a "comfort" letter from Coopers & Lybrand, LLP, independent public accountants for Beacon and Beacon Partnership, of the kind contemplated by the Statement of Auditing Standards with respect to Letters to Underwriters promulgated by the American Institute of Certified Public Accountants (the "AICPA Statement"), dated as of the date on which the Form S-4 shall become effective and as of the Effective Time, addressed to EOP and EOP Partnership, in form and substance reasonably satisfactory to EOP and EOP Partnership, concerning the procedures undertaken by Coopers & Lybrand, LLP with respect to the financial statements and information of Beacon, Beacon Partnership and their subsidiaries contained in the Form S-4 and the other matters contemplated by the AICPA Statement and otherwise customary in scope and substance or letters delivered by independent public accountants in connection with transactions such as those contemplated by this Agreement and (ii) Beacon shall have received a "comfort" letter from Ernst & Young LLP, independent public accountants for EOP and EOP Partnership, of the kind contemplated by the AICPA Statement, dated as of the date on which the Form S-4 shall become effective and as of the Effective Time, addressed to Beacon and Beacon Partnership, in form and substance reasonably satisfactory to Beacon, concerning the procedures undertaken by Ernst & Young, LLP with respect to the financial statements and information of EOP, EOP Partnership and their subsidiaries contained in the Form S-4 and the other matters contemplated by the AICPA Statement and otherwise customary in scope and substance for letters delivered by independent public accountants in connection with transactions such as those contemplated by this Agreement. (c) EOP will duly call and as soon as practicable following the date of this Agreement (but in no event sooner than 20 business days following the date the Proxy Statement is mailed to the shareholders of EOP), give notice of, convene and hold a meeting of its shareholders (the "EOP Shareholders Meeting") for the purpose of obtaining the EOP Shareholder Approvals. EOP will, through its Board of Trustees, recommend to its shareholders approval of this Agreement, the Merger, and the transactions contemplated by this Agreement. (d) On or before September 22, 1997, EOP and EOP Partnership shall deliver to Beacon and Beacon Partnership (i) a list of all information to be provided by Beacon or Beacon Partnership that is required to be -48- 57 included in the Proxy Statement in accordance with the applicable provisions of the Securities Act, the Exchange Act and the rules and regulations thereunder and (ii) an irrevocable letter of credit in the face amount of $10,000,000 issued by a bank reasonably acceptable to the parties, naming Beacon Partnership as beneficiary, expiring no sooner than June 1, 1998 and payable at site upon presentation of a sight draft and an affidavit of Beacon Partnership stating that all conditions to a draw under the letter of credit pursuant to this Section 5.1(d) have been met and the beneficiaries are entitled to draw the full amount thereunder. In addition, in the event that EOP and EOP Partnership shall fail to file the Proxy Statement with the SEC within fifteen (15) days after EOP and EOP Partnership have received all information requested pursuant to clause (i) above substantially in final form, EOP and EOP Partnership shall deliver to Beacon and Beacon Partnership another irrevocable letter of credit in the face amount of $5,000,000 and otherwise satisfying the requirements of clause (ii) above. In the event Beacon shall terminate this Agreement pursuant to Section 7.1(e), and provided that Beacon shall not have breached in any material respect its obligations under this Agreement in any manner that shall have caused the occurrence of either of the events referred to in clauses (x) and (y) to this Section 5.1(d), then at any time following the expiration of three (3) business days after EOP's receipt of written notice of such termination, Beacon shall be entitled to draw on the letter(s) of credit posted pursuant to this Section 5.1(c) if either of the following events has occurred: (x) EOP and EOP Partnership shall have failed to file the Proxy Statement with the SEC within fifteen (15) days after EOP and EOP Partnership have received all information requested pursuant to clause (i) above substantially in final form or (y) the Form S-4 shall not have been declared effective by the SEC on or before February 27, 1998. The receipt of Beacon and Beacon Partnership of any amounts pursuant to this Section 5.1(d) shall not affect the other remedies, if any, available to such parties. (e) Beacon will duly call and give notice of and, as soon as practicable following the date of this Agreement (but in no event sooner than 20 business days following the date the Proxy Statement is mailed to the shareholders of Beacon), convene and hold a meeting of its shareholders (the "Beacon Shareholders Meeting") for the purpose of obtaining Beacon Shareholder Approvals. Beacon will, through its Board of Directors, recommend to its shareholders approval of this Agreement, the Merger and the transactions contemplated by this Agreement and include such recommendation in the Proxy Statement; provided, however, that prior to the Beacon Shareholders Meeting, such recommendation may be withdrawn, modified or amended if a majority of the Board of Directors of Beacon determines in good faith, based upon the advice of its outside counsel, that such action is required for the Board of Directors of Beacon to comply with its duties to its shareholders imposed by applicable law. (f) EOP and Beacon shall use their best efforts to convene their respective shareholder meetings on the same day, which day, subject to the -49- 58 provisions of Sections 5.1(c), 5.1(d) and 5.3, shall be a day not later than 45 days after the date the Proxy Statement is mailed. (g) If on the date for the EOP Shareholders Meeting and Beacon Shareholders Meeting established pursuant to Section 5.1(f) of this Agreement, either EOP or Beacon has not received duly executed proxies for a sufficient number of votes to approve the Merger (but less than a majority of the outstanding Beacon Common Shares or EOP Common Shares, as the case may be, have voted against the Merger), then both parties shall recommend the adjournment of their respective shareholders meetings until one or more dates not later than the date ten (10) days after the originally scheduled date of the shareholders meetings. (h) Beacon will request written consents for approval by the limited partners of Beacon Partnership of each of the matters described in the definition of Beacon Partner Approvals. Beacon hereby agrees to vote in favor of such matters and to recommend to the limited partners of Beacon Partnership that they approve such matters. EOP will request written consents, if any is required, by the limited partners, of EOP Partnership of each of the matters described in the definition of EOP Partner Approvals. EOP hereby agrees to vote, if any is required, in favor of such matters and to recommend to the limited partners of EOP Partnership that they approve such matters. 5.2 Access to Information; Confidentiality. Subject to the requirements of confidentiality agreements with third parties, each of the parties shall, and shall cause each of its Subsidiaries to, afford to the other parties and to the officers, employees, accountants, counsel, financial advisors and other representatives of such other parties, reasonable access during normal business hours prior to the Effective Time to all their respective properties, books, contracts, commitments, personnel and records and, during such period, each of the parties shall, and shall cause each of its Subsidiaries to, furnish promptly to the other parties (a) a copy of each report, schedule, registration statement and other document filed by it during such period pursuant to the requirements of federal or state securities laws and (b) all other information concerning its business, properties and personnel as such other party may reasonably request. Each of the parties shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to cause its officers, employees, accountants, counsel, financial advisors and other representatives and affiliates to, hold any nonpublic information in confidence. 5.3 Reasonable Best Efforts; Notification. (a) Subject to the terms and conditions herein provided, each of the parties shall: (i) use all reasonable best efforts to cooperate with one another in (A) determining which filings are required to be made prior to the Effective Time -50- 59 with, and which consents, approvals, permits or authorizations are required to be obtained prior to the Effective Time from, governmental or regulatory authorities of the United States, the several states and foreign jurisdictions and any third parties in connection with the execution and delivery of this Agreement, and the consummation of the transactions contemplated hereby and (B) timely making all such filings and timely seeking all such consents, approvals, permits and authorizations; (ii) use all reasonable best efforts (other than the payment of money) to obtain in writing any consents required from third parties to effectuate the Merger, such consents to be in form reasonably satisfactory to each of the parties; and (iii) use all reasonable best efforts to take, or cause to be taken, all other action and do, or cause to be done, all other things necessary, proper or appropriate to consummate and make effective the transactions contemplated by this Agreement. If at any time after the Effective Time any further action is necessary or desirable to carry out the purpose of this Agreement, each party shall take all such necessary action. (b) Beacon and Beacon Partnership shall use all reasonable best efforts to obtain from Coopers & Lybrand, LLP, access to all work papers relating to audits of Beacon and Beacon Partnership performed by Coopers & Lybrand, LLP, and the continued cooperation of Coopers & Lybrand, LLP, with regard to the preparation of consolidated financial statements for the Surviving Trust. (c) Beacon and Beacon Partnership shall give prompt notice to EOP and EOP Partnership, and EOP and EOP Partnership shall give prompt notice to Beacon and Beacon Partnership, (i) if any representation or warranty made by it contained in this Agreement that is qualified as to materiality becomes untrue or inaccurate in any respect or any such representation or warranty that is not so qualified becomes untrue or inaccurate in any material respect or (ii) of the failure by it to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement. 5.4 Tax Treatment. Each of EOP and Beacon shall use its reasonable best efforts before and after the Effective Time to cause the Merger to qualify as a reorganization under the provisions of Sections 368(a) of the Code and to obtain the opinions of counsel referred to in Sections 6.2(e) and 6.3(e). If, based upon the advice of counsel, EOP and Beacon determine that the Partnership Merger could reasonably be expected to create a risk that the Merger would not qualify as a reorganization under the provisions of Section 368(a) of the Code, EOP and Beacon undertake to use reasonable best efforts to negotiate and structure an alternative means to effect the Merger, for EOP to acquire the interest in Beacon Partnership -51- 60 owned by Beacon, and for the holders of Beacon OP Units to receive EOP OP Units (or the economic and tax equivalent thereof) in exchange for their Beacon OP Units. EOP Partnership will use the "traditional method" under Treasury Regulations Section 1.704-3(b) for purposes of making allocations under Section 704(c) of the Code with respect to the properties of or interests in the Beacon Partnership as of the Effective Time (with no curative allocations of gross income with respect to depreciation to offset the effects of the "ceiling rule" but with a curative allocation of gain upon disposition of such properties to offset the effect of the "ceiling rule"). EOP Partnership and Beacon Partnership shall negotiate in good faith to agree upon the "Section 704(c) values" of the properties of Beacon Partnership, effective as of the Closing Date. For purposes of allocating "excess nonrecourse liabilities" of the EOP Partnership pursuant to Treasury Regulations Section 1.752-3(a)(3) following the Closing Date, EOP Partnership shall use a methodology to be agreed upon between EOP Partnership and Beacon Partnership. 5.5 Public Announcements. Each party will consult with each other party before issuing, and provide each other the opportunity to review and comment upon, any press release or other written public statements which address in any manner the transactions contemplated by this Agreement, and shall not issue any such press release or make any such written public statement prior to such consultation, except as may be required by applicable law, court process or by obligations pursuant to any listing agreement with any national securities exchange. The parties agree that the initial press release to be issued with respect to the transactions contemplated by this Agreement will be in the form agreed to by the parties prior to the execution of this Agreement. 5.6 Listing. EOP shall use all reasonable best efforts to cause the EOP Common Shares and the EOP Preferred Shares to be issued in the Merger and the EOP Common Shares reserved for issuance upon redemption of EOP OP Units issued in the Partnership Merger, to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Effective Time. 5.7 Transfer and Gains Taxes. Each party shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added stock transfer and stamp taxes, any transfer, recording, registration and other fees and any similar taxes which become payable in connection with the transactions contemplated by this Agreement (together with any related interests, penalties or additions to tax, "Transfer and Gains Taxes"). From and after the Effective Time, EOP shall pay or cause EOP Operating Partnership, as appropriate, to pay or cause to be paid, without deduction or withholding from any amounts payable to the holders of EOP Common Shares and EOP Preferred Shares, or EOP OP Units, as applicable, all Transfer and Gains Taxes (which term shall not in any event be construed to include for these purposes any tax imposed under the Code). -52- 61 5.8 Benefit Plans and Other Employee Arrangements. (a) Benefit Plans. After the Effective Time, all employees of Beacon who are employed by the Surviving Trust shall, at the option of the Surviving Trust, either continue to be eligible to participate in an "employee benefit plan", as defined in Section 3(3) of ERISA, of Beacon which is, at the option of the Surviving Trust, continued by the Surviving Trust, or alternatively shall be eligible to participate in the same manner as other similarly situated employees of the Surviving Trust who were formerly employees of EOP in any "employee benefit plan," as defined in Section 3(3) of ERISA, sponsored or maintained by the Surviving Trust after the Effective Time. With respect to each such employee benefit plan, service with Beacon or any Beacon Subsidiary (as applicable) and the predecessor of any of them shall be included for purposes of determining eligibility to participate, vesting (if applicable) and entitlement to benefits. (b) Stock Option Plan. The stock option plan of Beacon shall be discontinued. (c) Beacon Stock Options. As of the Effective Time, each outstanding Beacon Stock Option shall vest and be immediately exercisable, be assumed by EOP, and be deemed to constitute an option to acquire the same number of EOP Common Shares as the holder of such Beacon Stock Option would have been entitled to receive pursuant to the Merger had such holder exercised such Beacon Stock Option in full immediately prior to the Effective Time at a price per share equal to the aggregate exercise price for the Beacon Common Shares subject to such Beacon Stock Option divided by the number of full EOP Common Shares deemed to be purchasable pursuant to such Beacon Stock Option; provided, however, that the number of EOP Common Shares that may be purchased upon exercise of such Beacon Stock Option shall not include any fractional share and, upon the first such exercise of such Beacon Stock Option, a cash payment shall be made for any fractional share calculated in accordance with and in the manner provided for calculations as to be paid in lieu of fractional shares as part of the Merger Consideration under Section 1.10. All such Beacon Stock Options held by directors and officers of Beacon above the office of Vice President shall remain exercisable for one day after the Closing Date and shall expire at 11:59 p.m., New York time, on the day next business day following the Closing Date and all such Beacon Stock Options held by persons other than directors and officers of Beacon above the office of Vice President shall expire on the six month anniversary of the Closing Date if such person's employment does not terminate prior to or during such six-month period; provided, however, that EOP shall use its reasonable best efforts to enable each person who holds Beacon Stock Options as of the Effective Time and who exercises (with no requirement to deliver funds or withholding amounts until settlement) such Beacon Stock Options subsequent to the Effective Time but prior to 11:59 p.m., New York time, on the next business day following the Closing Date to receive (other than from EOP or any EOP Subsidiary), within four (4) business days after the Effective Time, an amount per Beacon Stock Option equal to the excess, if any, of (A) the closing price of one EOP Common Share on the New York Stock Exchange (the "NYSE") on the next business day following the Closing Date, over (B) the sum of (i) the exercise price of such Beacon Stock Option divided by the Exchange Ratio plus (ii) with respect to directors and officers of Beacon above the office of Vice President, an amount equal to any reasonable and customary brokerage commissions payable with respect to the sale of EOP Common Shares in connection with such option exercise; and, if EOP is unsuccessful in enabling each -53- 62 such person to receive such amount, then such Beacon Stock Option shall not expire prior to its stated expiration date and EOP shall use its reasonable best efforts to make other arrangements to enable each such person to receive the full economic benefit of such amount (provided that neither EOP nor any EOP Subsidiary shall have any obligation to pay to any such person any amount of cash or cash equivalents with respect to his or her Beacon Stock Options). (d) Withholding. To the extent required by applicable law, Beacon shall require each employee who exercises a Beacon Stock Option or who receives Beacon Common Shares pursuant to any existing commitment to pay to Beacon in cash or Beacon Common Shares an amount sufficient to satisfy in full Beacon's obligation to withhold Taxes incurred by reason of such exercise or issuance. 5.9 Indemnification. (a) From and after the Effective Time, EOP and EOP Partnership (collectively, the "Indemnifying Parties") shall provide exculpation and indemnification for each person who is now or has been at any time prior to the date hereof or who becomes prior to the Effective Time, an officer or director of Beacon or any Beacon Subsidiary (the "Indemnified Parties") which is the same as the exculpation and indemnification provided to the Indemnified Parties by Beacon and the Beacon Subsidiaries immediately prior to the Effective Time in its charter, Bylaws or in its partnership, operating or similar agreement, as in effect on the date hereof; provided, however, that such exculpation and indemnification covers actions on or prior to the Effective Time, including, without limitation, all transactions contemplated by this Agreement. (b) In addition to the rights provided in Section 5.9(a) above, in the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including without limitation, any action by or on behalf of any or all security holders of Beacon or EOP, or any Beacon Subsidiary or EOP Subsidiary, or by or in the right of Beacon or EOP, or any Beacon Subsidiary or EOP Subsidiary, or any claim, action, suit, proceeding or investigation in which any person who is now, or has been, at any time prior to the date hereof, or who becomes prior to the Effective Time, an officer, employee or director of Beacon or any Beacon Subsidiary (the "Indemnification Parties") is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was an -54- 63 officer, employee or director of Beacon or any of the Beacon Subsidiaries or any action or omission by such person in his capacity as a director, or (ii) this Agreement or the transactions contemplated by this Agreement, whether in any case asserted or arising before or after the Effective Time, EOP, Beacon and the Indemnified Parties, hereby agree to use their reasonable best efforts to cooperate in the defense of such claim, action, suit, proceeding or investigation. The Indemnified Parties shall have the right to select counsel, subject to the consent of the Indemnifying Parties (which consent shall not be unreasonably withheld or delayed). It is understood and agreed that, after the Effective Time, the Indemnifying Parties shall indemnify and hold harmless, as and to the full extent permitted by applicable law, each Indemnified Party against any losses, claims, liabilities, expenses (including reasonable attorneys' fees and expenses), judgments, fines and amounts paid in settlement in accordance herewith in connection with any such threatened or actual claim, action, suit, proceeding or investigation. In addition, after the Effective Time, in the event of any such threatened or actual claim, action, suit, proceeding or investigation, the Indemnifying Parties shall promptly pay and advance reasonable expenses and costs incurred by each Indemnified Person as they become due and payable in advance of the final disposition of the claim, action, suit, proceeding or investigation to the fullest extent and in the manner permitted by law. Notwithstanding the foregoing, the Indemnifying Parties shall not be obligated to advance any expenses or costs prior to receipt of an undertaking by or on behalf of the Indemnified Party to repay any expenses advanced if it shall ultimately be determined that the Indemnified Party is not entitled to be indemnified against such expense. Notwithstanding anything to the contrary set forth in this Agreement, the Indemnifying Parties (i) shall not be liable for any settlement affected without their prior written consent, and (ii) shall not have any obligation hereunder to any Indemnified Party to the extent that a court of competent jurisdiction shall determine in a final and non-appealable order that such indemnification is prohibited by applicable law. In the event of a final and non-appealable determination by a court that any payment of expenses is prohibited by applicable law, the Indemnified Person shall promptly refund to the Indemnifying Parties the amount of all such expenses theretofore advanced pursuant hereto. Any Indemnified Party wishing to claim indemnification under this Section 5.9, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify the Indemnifying Parties of such claim and the relevant facts and circumstances with respect thereto; provided, however, that the failure to provide such notice shall not affect the obligations of EOP except to the extent such failure to notify materially prejudices the Indemnifying Parties ability to defend such claim, action, suit, proceeding or investigation; and provided, further, however, that no Indemnified Party shall be obligated to provide any notification pursuant to this Section 5.9(b) prior to the Effective Time. -55- 64 (c) At or prior to the Effective Time, EOP shall purchase directors' liability insurance policy coverage for Beacon's executive officers for a period of six years which will provide the directors and officers with coverage on substantially similar terms as currently provided by Beacon to such directors and officers. Beacon shall have the right to reasonably review and approve any such policy, which approval shall not be unreasonably withheld. (d) This Section 5.9 is intended for the irrevocable benefit of, and to grant third party rights to, the Indemnified Parties and their successors, assigns and heirs and shall be binding on all successors and assigns of EOP.
