As used in this Agreement, the term &#8220;Affiliate&#8221; shall have the same<br \/>\nmeaning as such term is defined in Rule 405 promulgated under the Securities<br \/>\nAct.<\/p>\n<p>                2.12 Employee Benefits. As used herein, the term &#8220;Employee Plan&#8221;<br \/>\nincludes any pension, retirement, savings, disability, medical, dental, health,<br \/>\nlife, death benefit, group insurance, profit sharing, deferred compensation,<br \/>\nstock option, bonus, incentive, vacation pay, tuition reimbursement, severance<br \/>\npay, or other employee benefit plan, trust, agreement, contract, agreement,<br \/>\npolicy or commitment (including, without limitation, any pension plan, as<br \/>\ndefined in Section 3(2) of the Employee Retirement Income Security Act of 1974,<br \/>\nas amended, and the rules and regulations promulgated thereunder (&#8220;ERISA&#8221;)<br \/>\n(&#8220;Pension Plan&#8221;), and any welfare plan as defined in Section 3(1) of ERISA<br \/>\n(&#8220;Welfare Plan&#8221;)), whether any of the foregoing is funded, insured or<br \/>\nself-funded, written or oral, (i) sponsored or maintained by Beacon or its<br \/>\nSubsidiaries (each a &#8220;Controlled Group Member&#8221;) and covering any Controlled<br \/>\nGroup Member&#8217;s active or former employees (or their beneficiaries), (ii) to<br \/>\nwhich any Controlled Group Member is a party or by which any Controlled Group<br \/>\nMember (or any of the rights, properties or assets thereof) is bound or (iii)<br \/>\nwith respect to which any current Controlled Group Member may otherwise have any<br \/>\nmaterial liability (whether or not such Controlled Group Member still maintains<br \/>\nsuch Employee Plan). Each Employee Plan is listed on Schedule 2.12 to the Beacon<br \/>\nDisclosure Letter. With respect to the Employee Plans:<\/p>\n<p>                (a) Except as proposed in Schedule 2.12(a) to the Beacon<br \/>\nDisclosure Letter, no Controlled Group Member has any continuing liability<br \/>\nunder any Welfare Plan which provides for continuing benefits or coverage for<br \/>\nany participant or any beneficiary of a participant after such participant&#8217;s<br \/>\ntermination of employment, except as may be required by Section 4980B of the<br \/>\nCode or Section 601 (et seq.) of ERISA, or under any applicable state law, and<br \/>\nat the expense of the participant or the beneficiary of the participant.<\/p>\n<p>                (b) Each Employee Plan complies in all material respects with<br \/>\nthe applicable requirements of ERISA and any other applicable law governing such<br \/>\nEmployee Plan, and, to the best Knowledge of Beacon, each Employee Plan has at<br \/>\nall times been properly administered in all material respects in accordance with<br \/>\nall such requirements of law, and in accordance with its terms and the terms of<br \/>\nany applicable collective bargaining agreement to the extent consistent with all<br \/>\nsuch requirements of law. Each Pension Plan which is intended to be qualified is<br \/>\nqualified under Section 401(a) of the Code, has received a favorable<br \/>\ndetermination letter from the IRS stating that such Plan meets the requirements<br \/>\nof Section 401(a) of the Code and that the trust associated with such Plan is<br \/>\ntax-exempt under Section 501(a) of the Code and, to the best Knowledge of<br \/>\nBeacon, no event has occurred which would jeopardize the qualified status of any<br \/>\nsuch plan or the tax exempt status of any such trust under Sections 401(a) and<br \/>\nSection 501(a) of the<\/p>\n<p>                                      -21-<\/p>\n<p>   30<\/p>\n<p>Code, respectively. No lawsuits, claims (other than routine claims for<br \/>\nbenefits) or complaints to, or by, any person or governmental entity have been<br \/>\nfiled, are pending, to the best Knowledge of Beacon, threatened with respect to<br \/>\nany Employee Plan and, to the best Knowledge of Beacon, there is no fact or<br \/>\ncontemplated event which would be expected to give rise to any such lawsuit,<br \/>\nclaim (other than routine claims for benefits) or complaint with respect to any<br \/>\nPension Plan. Without limiting the foregoing, the following are true with<br \/>\nrespect to each Employee Plan:<\/p>\n<p>                 (i)   all Controlled Group Members have complied in all<br \/>\n          material respects with the reporting and disclosure requirements of<br \/>\n          ERISA, the Code, or both, with respect to each Employee Plan and no<br \/>\n          Controlled Group Member has incurred any material liability in<br \/>\n          connection with such reporting or disclosure;<\/p>\n<p>                 (ii)  all contributions and payments with respect to Employee<br \/>\n          Plans that are required to be made by a Controlled Group Member with<br \/>\n          respect to periods ending on or before the Closing Date (including<br \/>\n          periods from the first day of the current plan or policy year to the<br \/>\n          Closing Date) have been, or will be, made or accrued before the<br \/>\n          Closing Date in accordance with the appropriate plan document,<br \/>\n          actuarial report, collective bargaining agreements or insurance<br \/>\n          contracts or arrangements or as otherwise required by ERISA or the<br \/>\n          Code; and<\/p>\n<p>                 (iii) with respect to each such Employee Plan, to the extent<br \/>\n          applicable, Beacon has delivered to or has made available to EOP true<br \/>\n          and complete copies of (A) plan documents, or any and all other<br \/>\n          documents that establish the existence of the plan, trust,<br \/>\n          arrangement, contract, policy or commitment and all amendments<br \/>\n          thereto, (B) the most recent determination letter, if any, received<br \/>\n          from the IRS, (C) the three most recent Form 5500 Annual Reports (and<br \/>\n          all schedules and reports relating thereto) and actuarial reports and<br \/>\n          (D) all related trust agreements, insurance contract or other funding<br \/>\n          agreements that implement each such Employee Plan.<\/p>\n<p>                 (c) With respect to each Employee Plan, to the best Knowledge<br \/>\nof Beacon, there has not occurred, and no person or entity is contractually<br \/>\nbound to enter into, any &#8220;prohibited transaction&#8221; within the meaning of Section<br \/>\n4975(c) of the Code or Section 406 of ERISA, which transaction is not exempt<br \/>\nunder Section 4975(d) of the Code or Section 408 of ERISA and which could<br \/>\nsubject Beacon or any Controlled Group Member to material liability.<\/p>\n<p>                 (d) Except as disclosed in Schedule 2.12(d) to the Beacon<br \/>\nDisclosure Letter, no Controlled Group Member has maintained or been obligated<br \/>\nto contribute to any Employee Plan subject to Code Section 412 or Title IV of<\/p>\n<p>                                      -22-<br \/>\n   31<br \/>\nERISA. No Employee Plan subject to Code Section 412 or Title IV of ERISA has<br \/>\nbeen terminated.<\/p>\n<p>                (e) With respect to each pension plan maintained by any<br \/>\nControlled Group Member, such Plans provide the Plan Sponsor the authority to<br \/>\namend or terminate the Plan at any time, subject to applicable requirements of<br \/>\nERISA and the Code.<\/p>\n<p>            2.13 Employee Policies. No employee handbook of Beacon or any of the<br \/>\nBeacon Subsidiaries is currently in effect. Schedule 2.13 to the Beacon<br \/>\nDisclosure Letter fairly and accurately summarizes all material employee<br \/>\npolicies, vacation policies and payroll policies.<\/p>\n<p>            2.14 Taxes.<\/p>\n<p>                (a) Each of Beacon and the Beacon Subsidiaries (A) has filed all<br \/>\nTax returns and reports required to be filed by it (after giving effect to any<br \/>\nfiling extension properly granted by a Governmental Entity having authority to<br \/>\ndo so) and all such returns and reports are accurate and complete in all<br \/>\nmaterial respects, and (B) has paid (or Beacon has paid on its behalf) all Taxes<br \/>\n(as defined below) shown on such returns and reports as required to be paid by<br \/>\nit, except those where the failure to file such tax returns and reports or pay<br \/>\nsuch Taxes would not have a Beacon Material Adverse Effect. The most recent<br \/>\naudited financial statements contained in the Beacon SEC Documents reflect an<br \/>\nadequate reserve for all material Taxes payable by Beacon and the Beacon<br \/>\nSubsidiaries for all taxable periods and portions thereof through the date of<br \/>\nsuch financial statements. Since the Beacon Financial Statement Date, Beacon has<br \/>\nincurred no liability for taxes under Sections 857(b), 860(c) or 4981 of the<br \/>\nCode, including without limitation any tax arising from a prohibited transaction<br \/>\ndescribed in Section 857(b)(6) of the Code, and neither Beacon nor any Beacon<br \/>\nSubsidiary has incurred any material liability for taxes other than in the<br \/>\nordinary course of business. No event has occurred, and no condition or<br \/>\ncircumstance exists, which presents a material risk that any material Tax<br \/>\ndescribed in the preceding sentence will be imposed upon Beacon. To the<br \/>\nKnowledge of Beacon, no deficiencies for any Taxes have been proposed, asserted<br \/>\nor assessed against Beacon or any of the Beacon Subsidiaries, and no requests<br \/>\nfor waivers of the time to assess any such Taxes are pending. As used in this<br \/>\nAgreement, &#8220;Taxes&#8221; shall include all federal, state, local and foreign income,<br \/>\nproperty, sales, franchise, employment, excise and other taxes, tariffs or<br \/>\ngovernmental charges of any nature whatsoever, together with penalties, interest<br \/>\nor additions to Tax with respect thereto.<\/p>\n<p>                (b) Beacon and BeaMetFed, Inc. (&#8220;BeaMet&#8221;) (i) for all taxable<br \/>\nyears commencing with 1994 (or, in the case of BeaMet, 1995) through December<br \/>\n31, 1996 has been subject to taxation as a real estate investment trust (a<br \/>\n&#8220;REIT&#8221;) within the meaning of Section 856 of the Code and has satisfied all<br \/>\nrequirements to<\/p>\n<p>                                      -23-<\/p>\n<p>   32<\/p>\n<p>qualify as a REIT for such years, (ii) has operated since December 31, 1996 to<br \/>\nthe date of this representation, and intends to continue to operate, in such a<br \/>\nmanner as to qualify as a REIT for the taxable year ending December 31, 1997 and<br \/>\nfor the taxable year of Beacon ending on the Closing Date (or, in the case of<br \/>\nBeaMet, on December 31, 1998), and (iii) has not taken or omitted to take any<br \/>\naction which would reasonably be expected to result in a challenge to its status<br \/>\nas a REIT and, to Beacon&#8217;s Knowledge, no such challenge is pending or<br \/>\nthreatened. Each Beacon Subsidiary which is a partnership, joint venture or<br \/>\nlimited liability company (i) has been since its formation and continues to be<br \/>\ntreated for federal income tax purposes as a partnership and not as a<br \/>\ncorporation or an association taxable as a corporation and (ii) has not since<br \/>\nthe later of its formation or the acquisition by Beacon of a direct or indirect<br \/>\ninterest therein, owned any assets (including, without limitation, securities)<br \/>\nthat would cause Beacon to violate Section 856(c)(5) of the Code. No Beacon<br \/>\nSubsidiary (other than BeaMet, the Management Company, the Design Company and<br \/>\nthe Construction Company) is a corporation (or an entity that would, under<br \/>\napplicable federal income tax principles, be classified as an association<br \/>\ntaxable as a corporation). Beacon Partnership is not a publicly traded<br \/>\npartnership within the meaning of Section 7704 of the Code. Neither Beacon nor<br \/>\nany Beacon Subsidiary holds any asset (x) the disposition of which would be<br \/>\nsubject to rules similar to Section 1374 of the Code as a result of a notice<br \/>\nunder IRS Notice 88-19 or (y) which is subject to a consent filed pursuant to<br \/>\nSection 341(f) of the Code and the regulations thereunder.<\/p>\n<p>            2.15 No Payments to Employees, Officers or Directors. Schedule 2.15<br \/>\nto the Beacon Disclosure Letter contains a true and complete list of all<br \/>\narrangements, agreements or plans pursuant to which cash and non-cash payments<br \/>\nwhich will become payable (and the maximum aggregate amount which may be payable<br \/>\nthereunder) to each employee, officer or director of Beacon or any Beacon<br \/>\nSubsidiary as a result of the Merger or a termination of service subsequent to<br \/>\nthe consummation of the Merger. Except as described in Schedule 2.15 to the<br \/>\nBeacon Disclosure Letter, or as otherwise provided for in this Agreement, there<br \/>\nis no employment or severance contract, or other agreement requiring payments,<br \/>\ncancellation of indebtedness or other obligation to be made on a change of<br \/>\ncontrol or otherwise as a result of the consummation of any of the transactions<br \/>\ncontemplated by this Agreement or as a result of a termination of service<br \/>\nsubsequent to the consummation of any of the transactions contemplated by this<br \/>\nAgreement, with respect to any employee, officer or director of Beacon or any<br \/>\nBeacon Subsidiary.<\/p>\n<p>            2.16 Broker; Schedule of Fees and Expenses. No broker, investment<br \/>\nbanker, financial advisor or other person, other than Morgan Stanley &amp; Co.,<br \/>\nIncorporated, the fees and expenses of which are described in the engagement<br \/>\nletter dated September 12, 1997, between Morgan Stanley &amp; Co., Incorporated and<br \/>\nBeacon, a true, correct and complete copy of which has previously been given to<br \/>\nEOP, is entitled to any broker&#8217;s, finder&#8217;s, financial advisor&#8217;s or other similar<br \/>\nfee or <\/p>\n<p>                                      -24-<br \/>\n   33<\/p>\n<p>commission in connection with the transactions contemplated hereby based<br \/>\nupon arrangements made by or on behalf of Beacon or any Beacon Subsidiary.<\/p>\n<p>            2.17 Compliance with Laws.

ordinance, order or regulation is or will<br \/>\nbe violated by the continued maintenance, operation or use of any buildings or<br \/>\nother improvements on any of the EOP Properties or by the continued maintenance,<br \/>\noperation or use of the parking areas, other than such notices which, in the<br \/>\naggregate, would not have an EOP Material Adverse Effect.<\/p>\n<p>                (f) All work to be performed, payments to be made and actions to<br \/>\nbe taken by EOP or the EOP Subsidiaries prior to the date hereof pursuant to any<br \/>\nagreement entered into with a governmental body or authority in connection with<br \/>\na site approval, zoning reclassification or similar action relating to any EOP<br \/>\nProperties (e.g., Local Improvement District, Road Improvement District,<br \/>\nEnvironmental Mitigation), has been performed, paid or taken, as the case may<br \/>\nbe, except where the failure to do so would, in the aggregate, not have an EOP<br \/>\nMaterial Adverse Effect, and EOP has no Knowledge of any planned or proposed<br \/>\nwork, payments or actions that may be required after the date hereof pursuant to<br \/>\nsuch agreements.<\/p>\n<p>                (g) The rent roll previously provided by EOP to Beacon (the &#8220;EOP<br \/>\nRent Roll&#8221;) lists each EOP Space Lease (as defined below) in effect as of the<br \/>\nrespective dates in August 1997 indicated in the EOP Rent Roll.  &#8220;EOP Space<br \/>\nLease&#8221; means each lease or other right of occupancy affecting or relating to a<br \/>\nproperty in which EOP Partnership (or an entity in which it directly or<br \/>\nindirectly has an interest) is the landlord, either pursuant to the terms of<br \/>\nthe lease agreement or as successor to any prior landlord, but excluding any<br \/>\nground lease. EOP has made available to Beacon true, correct and complete<br \/>\ncopies of all EOP Space Leases, including all amendments, modifications,<br \/>\nsupplements, renewals, extensions and guarantees related thereto, as of the<br \/>\ndate hereof. Except for discrepancies that, either individually or in the<br \/>\naggregate, would not reasonably be expected to have an EOP Material Adverse<br \/>\nEffect, all information set forth in the EOP Rent Roll is true, correct, and<br \/>\ncomplete as of the date thereof. Except as set forth in a delinquency report<br \/>\nmade available to EOP, neither EOP nor any EOP Subsidiary, on the one hand,<br \/>\nnor, to the Knowledge of EOP or EOP Partnership, any other party, on the other<br \/>\nhand, is in monetary<\/p>\n<p>                                      -35-<br \/>\n   44<\/p>\n<p>default under any EOP Space Lease, except for such defaults that would not<br \/>\nreasonably be expected to have a Material Adverse Effect.<\/p>\n<p>            3.10 Environmental Matters. Except as disclosed in the EOP SEC<br \/>\nDocuments or on Schedule 3.10 to the EOP Disclosure Letter, (a) none of EOP, any<br \/>\nof the EOP Subsidiaries or, to EOP&#8217;s Knowledge, any other Person has caused or<br \/>\npermitted the unlawful presence of any Hazardous Materials on or under any of<br \/>\nthe EOP Properties or (b) any unlawful spills, releases, discharges or disposal<br \/>\nof Hazardous Materials to have occurred or be presently occurring on, under or<br \/>\nfrom the EOP Properties as a result of any construction on or operation and use<br \/>\nof such properties, which presence or occurrence would, individually or in the<br \/>\naggregate, have an EOP Material Adverse Effect; and in connection with the<br \/>\nconstruction on or operation and use of the EOP Properties, EOP and the EOP<br \/>\nSubsidiaries have not failed to comply in any material respect with all<br \/>\napplicable local, state and federal environmental laws, regulations, ordinances<br \/>\nand administrative and judicial orders relating to the generation, recycling,<br \/>\nreuse, sale, storage, handling, transport and disposal of any Hazardous<br \/>\nMaterials, except to the extent such failure to comply, individually or in the<br \/>\naggregate, would not have an EOP Material Adverse Effect.<\/p>\n<p>            3.11 Taxes.<\/p>\n<p>                 (a) Each of EOP and the EOP Subsidiaries (i) has filed all Tax<br \/>\nreturns and reports required to be filed by it (after giving effect to any<br \/>\nfiling extension properly granted by a Governmental Entity having authority to<br \/>\ndo so), and all such returns and reports are accurate and complete in all<br \/>\nmaterial respects, and (ii) has paid (or EOP has paid on its behalf) all Taxes<br \/>\nshown on such returns and reports as required to be paid by it except where the<br \/>\nfailure to file such tax returns or reports and failure to pay such Taxes would<br \/>\nnot have an EOP Material Adverse Effect. The most recent audited financial<br \/>\nstatements contained in the EOP SEC Documents reflect an adequate reserve for<br \/>\nall material Taxes payable by EOP and the EOP Subsidiaries for all taxable<br \/>\nperiods and portions thereof through the date of such financial statements.<br \/>\nSince the EOP Financial Statement Date, EOP has incurred no liability for taxes<br \/>\nunder Sections 857(b), 860(c) or 4981 of the Code, including without limitation<br \/>\nany tax arising from a prohibited transaction described in Section 857(b)(6) of<br \/>\nthe Code, and neither EOP nor any EOP Subsidiary has incurred any material<br \/>\nliability for taxes other than in the ordinary course of business. No event has<br \/>\noccurred, and no condition or circumstance exists, which presents a material<br \/>\nrisk that any material Tax described in the preceding sentence will be imposed<br \/>\nupon EOP. To the Knowledge of EOP, no deficiencies for any Taxes have been<br \/>\nproposed, asserted or assessed against EOP or any of the EOP Subsidiaries, and<br \/>\nno requests for waivers of the time to assess any such Taxes are pending.<\/p>\n<p>                 (b) EOP (i) has operated, and intends to continue to operate,<br \/>\nin such a manner as to qualify as a REIT within the meaning of Section 856 of<br \/>\nthe <\/p>\n<p>                                      -36-<br \/>\n   45<\/p>\n<p>Code for the taxable year ending December 31, 1997 and intends to continue<br \/>\nto operate in such a manner as to qualify as a REIT for the taxable year that<br \/>\nincludes the Closing Date and (ii) has not taken or omitted to take any action<br \/>\nwhich would reasonably be expected to result in a challenge to its status as a<br \/>\nREIT, and to EOP&#8217;s Knowledge, no such challenge is pending or threatened. Each<br \/>\nEOP Subsidiary which is a partnership, joint venture or limited liability<br \/>\ncompany (i) has been treated since its formation and continues to be treated for<br \/>\nfederal income tax purposes as a partnership and not as a corporation or as an<br \/>\nassociation taxable as a corporation and (ii) has not since the later of its<br \/>\nformation or the acquisition by EOP of a direct or indirect interest therein,<br \/>\nowned any assets (including, without limitation, securities) that would cause<br \/>\nEOP to violate Section 856(c)(5) of the Code. Each EOP Subsidiary which is a<br \/>\ncorporation (other than EOP Management Corp.) has been since its formation a<br \/>\nqualified REIT subsidiary under Section 856(i) of the Code. EOP Partnership is<br \/>\nnot a publicly traded partnership within the meaning of Section 7704 of the<br \/>\nCode. Except as set forth in Schedule 3.11 to the EOP Disclosure Letter neither<br \/>\nEOP nor any EOP Subsidiary holds any asset (x) the disposition of which would be<br \/>\nsubject to rules similar to Section 1374 of the Code as a result of a notice<br \/>\nunder IRS Notice 88-19 or (y) which is subject to a consent filed pursuant to<br \/>\nSection 341(f) of the Code and the regulations thereunder.<\/p>\n<p>            3.12 Brokers; Schedule of Fees and Expenses. No broker, investment<br \/>\nbanker, financial advisor or other person, other than J.P. Morgan Securities<br \/>\nInc. and Merrill Lynch &amp; Co., the fees and expenses of which will be paid by EOP<br \/>\nand are described in the respective engagement letters with J.P. Morgan<br \/>\nSecurities Inc. and Merrill Lynch &amp; Co., true, correct and complete copies of<br \/>\nwhich have previously been given to Beacon, is entitled to any broker&#8217;s,<br \/>\nfinder&#8217;s, financial advisor&#8217;s or other similar fee or commission in connection<br \/>\nwith the transactions contemplated hereby based upon arrangements made by or on<br \/>\nbehalf of EOP or any EOP Subsidiary.<\/p>\n<p>            3.13 Compliance with Laws. Neither EOP nor any of the EOP<br \/>\nSubsidiaries has violated or failed to comply with any statute, law, ordinance,<br \/>\nregulation, rule, judgment, decree or order of any Governmental Entity<br \/>\napplicable to its business, properties or operations, except to the extent that<br \/>\nsuch violation or failure would not have an EOP Material Adverse Effect.<\/p>\n<p>            3.14 Contracts; Debt Instruments. Neither EOP nor any EOP Subsidiary<br \/>\nhas received a written notice that EOP or any EOP Subsidiary is in violation of<br \/>\nor in default under (nor to the Knowledge of EOP does there exist any condition<br \/>\nwhich upon the passage of time or the giving of notice or both would cause such<br \/>\na violation of or default under) any material loan or credit agreement, note,<br \/>\nbond, mortgage, indenture, lease, permit, concession, franchise, license or any<br \/>\nother material contract, agreement, arrangement or understanding, to which it is<br \/>\na party or by which it or any of its properties or assets is bound, nor to the<br \/>\nKnowledge of EOP does such a violation or default exist, except to the extent<br \/>\nsuch violation or<\/p>\n<p>                                      -37-<br \/>\n   46<\/p>\n<p>default, individually or in the aggregate, would not have an EOP Material<br \/>\nAdverse Effect, except as set forth in the EOP SEC Documents or in Schedule 3.14<br \/>\nto the EOP Disclosure Letter.<\/p>\n<p>            3.15 Opinion of Financial Advisor. EOP has received the oral opinion<br \/>\nof J.P. Morgan Securities Inc., satisfactory to EOP, to the effect that the<br \/>\nconsideration to be paid by EOP and EOP Partnership in connection with the<br \/>\nMergers is fair, from a financial point of view, to EOP and EOP Operating<br \/>\nPartnership.<\/p>\n<p>            3.16 State Takeover Statutes. EOP has taken all action necessary to<br \/>\nexempt transactions between EOP and Beacon and its Affiliates from the operation<br \/>\nof Takeover Statutes.<\/p>\n<p>            3.17 Investment Company Act of 1940. Neither EOP nor any of the EOP<br \/>\nSubsidiaries is, or at the Effective Time will be, required to be registered<br \/>\nunder the 1940 Act.<\/p>\n<p>            3.18 Definition of Knowledge of EOP. As used in this Agreement, the<br \/>\nphrase &#8220;Knowledge of EOP&#8221; (or words of similar import) means the knowledge of<br \/>\nthose individuals identified in Schedule 3.19 to the EOP Disclosure Letter.<\/p>\n<p>            3.19 EOP Not an Interested Stockholder. EOP is not an &#8220;interested<br \/>\nstockholder&#8221; of Beacon or an &#8220;affiliate of an interested stockholder&#8221; of Beacon<br \/>\nwithin the meaning of Section 3-601 of the MGCL.<\/p>\n<p>                                    ARTICLE 4<\/p>\n<p>                                    COVENANTS<\/p>\n<p>                4.1 Conduct of Beacon&#8217;s and Beacon Partnership&#8217;s Business<br \/>\nPending Merger.
