(d) The parties hereto shall take such additional actions and execute such additional documentation as may be required by the Organizational Documents, the OP Agreement or, in the reasonable judgment of counsel to the Operating Partnership, in order to effect fully the transactions contemplated hereby, including, without limitation, amendments to the Organizational Documents as required to admit the Operating Partnership or its designee as the owner of the Titleholder Interests in lieu of an Opportunity Partnership. 1.2 CALCULATION OF UNITS TO BE ISSUED. Subject to Section 1.3 below, the Operating Partnership shall at Closing, in consideration for the Contributed Opportunity Partnership Assets or the Management Business, as the case may be, transfer to each Contributor a number of Units equal to the product of: (x) the quotient of (i) the Adjusted Consideration (as defined below) for each such Contributor divided by (ii) the sum of the Adjusted Consideration for all Contributors (without regard to the proceeds from the IPO) multiplied by (y) the excess of (i) the quotient of (A) the number of shares of beneficial interest (without regard to any overallotment option) of Equity Office Properties Trust, a Maryland real estate investment trust (the 'Company' and the 'Common Shares') sold to the public in the initial public offering of such shares, when and if it occurs (the 'IPO') divided by (B) the fractional ownership interest (expressed in decimal form) in the Operating Partnership that the Common Shares sold in the IPO represent upon their issuance (without regard to any overallotment option) over (ii) the number of Common Shares sold in the IPO (without regard to any overallotment option). 3 1.3 ADJUSTED CONSIDERATION. (a) The 'Initial Consideration' for the real and tangible personal property interests included in each Opportunity Partnership's Contributed Opportunity Partnership Assets has been determined and fixed, on a collective basis, as of December 31, 1996 (the 'Initial Valuation Date') to be the dollar amount so designated on Exhibit A-1, A-2, A-3 or A-4. In order to determine the final valuation amount (the 'Adjusted Consideration') for each Opportunity Partnership's contribution to the Operating Partnership, its Initial Consideration amount shall be increased or decreased as of the last day of the calendar month first preceding the month in which the preliminary prospectus used in connection with the IPO is dated (the 'Final Valuation Date') as follows: first: by adding the amount of its cash then on hand (exclusive of cash held for the account of third parties) after deduction of (x) the sum which the Contributor estimates to be required to be distributed to its partners in order to make any Required REIT Distribution and (y) any additional sum which the Contributor elects to distribute thereafter to its partners from the proceeds of its prior sale of non-office assets; second: by adding the value (which shall be determined in good faith by the Operating Partnership and reasonably acceptable to such Contributor) of all intangible non-real estate assets (exclusive of cash and accounts receivable) to be contributed by such Contributor hereunder; third: by adding or deducting, as appropriate, a credit or charge (determined in good faith by the Operating Partnership and reasonably acceptable to the Contributor) reflective of the amount by which the terms of the Contributor's mortgage indebtedness are above or below prevailing market terms; fourth: by deducting the principal amount of all then-outstanding mortgage indebtedness of such Contributor (exclusive of such indebtedness having a remaining term of less than one year); fifth: by adding or deducting, as appropriate, the Net Proration Amount; sixth: by deducting the amount of any unexpended capital transaction proceeds paid to the Opportunity Partnership after the Initial Valuation Date and prior to the Final Valuation Date as a result of an insurance recovery or condemnation or assignment in lieu of condemnation; seventh: by adding or deducting, as appropriate, the amount by which the Consolidation Expenses paid or reserved by such Contributor exceeded or was less than such Contributor's proportionate share of all such Consolidation Expenses which were paid or reserved prior to the Final Valuation Date by all of the Contributors (calculated in the same proportion as its Initial Consideration amount bears to the aggregate of all Initial Consideration amounts) (each Contributor's 'Proportionate Expense Allocation Adjustment:); eighth: by deducting, in the case of Opportunity Partnership I, the Initial Consideration amounts for any Properties sold subsequent to the Initial Valuation Date and prior to the Final Valuation Date (being the aggregate sum of $66,625,000 for Barton Oaks and 8383 Wilshire); and ninth: by adding the gross purchase price for any Properties acquired by such Contributor subsequent to the Initial Valuation Date and prior to the Final Valuation Date. The parties agree that, inasmuch as Properties acquired or optioned subsequent to the Final Valuation Date will be purchased, in part, from cash balances reflected in clause first above and are not included in the Initial Consideration amounts, no adjustment is required to be made in the calculation of the Adjusted Consideration for Properties that may be acquired or optioned subsequent to the Final Valuation Date, notwithstanding that those Properties shall be included within the definition of the Opportunity Partnership's Contributed Opportunity Partnership Assets and in the determination of such Opportunity Partnership's Titleholder Interests. 4 (b) The 'Adjusted Consideration' for the Management Business is One Hundred Sixty Million Dollars ($160,000,000) and shall not be subject to adjustment, except only for any required Proportionate Expense Allocation Adjustment which Equity Office does not pay in cash at or prior to Closing. 1.4 TREATMENT AS CONTRIBUTION. The transfer, assignment and exchange of interests effectuated with respect to the Operating Partnership pursuant to this Contribution Agreement shall constitute a 'Capital Contribution' pursuant to Article IV of the OP Agreement and is intended to be governed by Section 721(a) of the Internal Revenue Code of 1986, as amended (the 'Code'). 2.

For purposes of this Section 3.2, the term 'material agreement' shall be defined with reference to the Property to which such agreement relates.

(p) Trademarks and Tradenames; Proprietary Rights. (i) There are no actions or other judicial or administrative proceedings involving the Opportunity Partnership, the Titleholders, or the Properties pending, or threatened in writing, that concern any copyrights, copyright application, trademarks, trademark registrations, trade names, service marks, service mark registrations, trade names and trade name registrations or any trade secrets being transferred to the Operating Partnership hereunder (the 'Proprietary Rights').

(r) No Brokers. Neither the Opportunity Partnership nor any of its general partners or the respective officers, directors or employees thereof has employed or made any agreement with any broker, finder or similar agent or any person or firm which will result in the obligation of the Operating Partnership or any of its affiliates to pay any finder's fee, brokerage fees or commissions or similar payment in connection with the transactions contemplated by this Contribution Agreement.

Except as set forth in such financial statements, neither any Contributor nor any 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 the Contributor or in the notes thereto and which, individually or in the aggregate, would have a Material Adverse Effect. 3.3 REPRESENTATIONS AND WARRANTIES OF EQUITY OFFICE. Each of EOH and EGI makes the following representations and warranties to the Operating Partnership solely with respect to itself and the Management Business contributed by it hereunder: (a) Organization; Authority. Each of EOH and EGI is duly formed, validly existing and in good standing (to the extent applicable) under the laws of the jurisdiction of its formation, and has all requisite power and authority to own, lease or operate its property and to carry on its business as presently conducted and, to the extent required under applicable law, is qualified to do business and is in good standing in each jurisdiction in which the nature of its business or the character of its property make such qualification necessary. (b) Due Authorization. The execution, delivery and performance of this Contribution Agreement by each of EOH and EGI has been duly and validly authorized by all necessary action of each of them. The Contribution Agreement has been duly executed and delivered by each of EOH and EGI and constitutes a legal, valid and binding obligation of each of them enforceable against each of them in accordance with its terms, as such enforceability may be limited by bankruptcy or the application of equitable principles. (c) Consents and Approvals. No consent, waiver, approval or authorization of any third party is required to be obtained by EOH or EGI in connection with the execution, delivery and performance by any of them of the Contribution Agreement and the transactions contemplated hereby, except for any of the foregoing that shall have been obtained prior to the Closing Date. (d) Ownership of the Management Business. Each of EOH and EGI is the sole owner of the Management Business to be contributed by it and has not pledged, assigned, hypothecated or otherwise encumbered such Management Business. EOH is the successor owner to all portions of the Management Business previously owned by its subsidiary entities, Equity Captial Holdings, L.L.C. and Equity Office Properties, L.L.C. (e) Management Contracts. A true and correct copy of all of the contracts or other written understandings, to which each of EOH and EGI is a party or by which EOH and EGI is bound that relate to its Management Business except for contracts or understandings that are not material to the business and operations of the Management Business (collectively, the 'Management Contracts') has been delivered to or made available to the Operating Partnership. Each of the Management Contracts is valid and binding and in full force and effect in all material respects. No party to the Management Contracts has breached or defaulted under the terms of any Management Contract, except for such breaches or defaults that would not have a material adverse effect on the condition, financial or otherwise, or on the earnings, assets, business affairs or business prospects of the Management Business. (f) Permits. To the Knowledge of EOH and EGI, each has such franchises, certificates, licenses, permits and other authorizations from governmental political subdivisions or regulatory authorities (collectively 'Permits') as are necessary for the ownership, use, operation and licensing of the Management Business, except for any Permits for which the failure to possess would not have a material adverse effect on the condition, financial or otherwise, or on the earnings, assets, business affairs or business prospects of the Management Business, and neither EOH nor EGI is in violation of any such material Permit in any material respect. (g) Non-Foreign Status. Neither EOH nor EGI is a foreign person, foreign corporation, foreign partnership, foreign trust or foreign estate (as defined in the Code), and none of them is, therefore, subject to the provisions of the Code relating to the withholding of sales proceeds to foreign persons. 12 (h) Investment Purposes. Each of EOH and EGI acknowledges its understanding that the offering and sale of the Units to be acquired pursuant to the Contribution Agreement are intended to be exempt from registration under the Act. In furtherance thereof, each of EOH and EGI represents and warrants only with respect to itself to the Company that it is an 'accredited investor' (as such term is defined in Rule 501(a) of Regulation D under the Act) and has no intention of engaging in a public distribution of such Units. (i) No Brokers. Neither EOH nor EGI nor any of its respective officers, directors or employees has incurred or will incur any liability for any brokerage fees, commissions or finders' fees that have been paid or may become payable by the Operating Partnership or any of its affiliates to any broker or finder engaged by or on behalf of any of them or any of their officers, directors or employees in connection with the transaction contemplated by this Contribution Agreement. (j) Compliance with Laws. Neither EOH nor EGI has received any written notice of any violation and there are no such violations, of any employment, environmental, or other regulatory law, order, regulation, or requirement relating to the Management Business which, individually or in the aggregate, would have a material adverse effect on the condition, financial or otherwise, or on the earnings, assets, business affairs or business prospects of the Management Business. (k) Insurance. Each of EOH and EGI currently has in place public liability, casualty and other insurance coverage with respect to the Management Business as is usual and customary for the conduct of similar businesses. To the Knowledge of EOH and EGI, each of the insurance policies with respect to the Management Business is in full force and effect. All premiums due and payable in respect to such insurance policies have been fully paid when due. Neither EOH nor EGI has received from any insurance company any notices of cancellation or intent to cancel any insurance. (l) Taxes. No tax lien or other charge exists or will exist upon consummation of the transactions contemplated hereby with respect to the Management Business except such tax liens for which the tax is not yet due and payable or tax liens or other charges which individually or in the aggregate would not have a material adverse effect on the Operating Partnership. (m) No Violation. None of the execution, delivery or performance of this Contribution Agreement and the transactions contemplated hereby does or will, with or without the giving of notice, lapse of time, or both, (i) violate, conflict with, result in a breach of, or constitute a default under or give to others any right of termination or cancellation of (A) the organizational documents of EOH or EGI, (B) any material agreement, document or instrument to which EOH or EGI or its Management Business is bound or (C) any term or provision of any judgment, order, writ, injunction, or decree of any Governmental Entity binding on EOH or EGI or any of its assets or properties or (ii) result in the creation of any Lien, other than Permitted Liens, upon the Management Business. (n) Solvency. Each of EOH and EGI has been and will be solvent at all times prior to and immediately following the transfer of the Management Business to the Operating Partnership.

To Knowledge, no representation, warranty or statement made, or information provided, by EOH, EGI or any Opportunity Partnership in this Contribution Agreement or in any other document or instrument furnished or to be furnished by or on behalf of EOH or EGI or any Opportunity Partnership pursuant hereto (i) contains or will contain any untrue statement of a material fact or (ii) intentionally omits or will intentionally omit to state a material fact necessary to make the statements contained herein or therein not misleading when read together with all other such documents and instruments. (p) Schedule of Liabilities and Assets. The schedule of liabilities and assets which Equity Office hereby agrees to deliver at or prior to Closing, calculated as of the Final Valuation Date in respect to the Management Business, shall be true, correct and complete in all material respects; provided that, for these purposes, a liability which has not been asserted in writing or is otherwise based on a written agreement shall not be deemed to exist 13 unless it is for goods and services provided or agreed to be provided and shall not include liabilities for which the Operating Partnership agrees that there are valid defenses to payment which are reasonably likely to prevail. 3.4 LEGENDING.

Any claim for indemnification under Sections 5.3 hereof must be asserted in writing by the Indemnified Party, as the case may be, stating the nature of the Losses and the basis for the indemnification therefor within one (1) year from and after the Closing. If so asserted in writing within one (1) year from and after the Closing, such claims for indemnification shall survive until resolved by mutual agreement between the parties to such claim or until final judicial determination.

The Operating Partnership hereby agrees to indemnify and hold harmless each of the Opportunity Partnerships, each of their constituent partners, Equity Office, its members and shareholders and each of their respective directors, members, managers, officers, employees, agents, representatives and affiliates (each an 'Indemnified Contributor Party') of and from and against any and all Losses asserted against, imposed upon or incurred by the Indemnified Contributor Party in connection with: (i) any breach of a representation or warranty of the Operating Partnership contained in this Contribution Agreement; (ii) any liabilities or obligations incurred, arising from or out of, in connection with or as a result of any Claims made or Actions brought by or against the Opportunity Partnership, the Titleholders, the Properties or an Indemnified Contributor Party, that arise from or out of, in connection with or as a result of any Contamination of the Properties regardless of when or how occurring, except to the extent, and only to the extent, such Losses arise from a breach of a representation and warranty of the Indemnified Contributor Party under Section 3.2 hereof; (iii) the operation or ownership of the Properties or the Titleholder Interests, whether before or after Closing (except to the extent such loss is attributable to a breach of a representation or warranty of the Indemnified Contributor Party contained herein); and (iv) all fees, costs and 15 expenses incurred in connection with the actions contemplated by this Contribution Agreement, including without limitation any and all costs associated with the transfers contemplated herein. 5.3 INDEMNIFICATION BY CONTRIBUTORS.

In addition, EOH and EGI hereby agree to indemnify and hold harmless the Operating Partnership from and against any and all Losses asserted against, imposed upon or incurred by the Operating Partnership as a result of its ownership or operation of the Management Business but only to the extent that such Losses are attributable to the period prior to the Closing Date. 5.4 NOTICE AND DEFENSE OF CLAIMS.

The Indemnified Party may at its option demand indemnity under this Section 5 as soon as a claim has been threatened by a third party, regardless of whether any actual Losses have been suffered, so long as the Indemnified Party shall in good faith determine that such claim is not frivolous and that the Indemnified Party may be liable for, or otherwise incur, Losses as a result thereof and shall give notice of such determination to the Contributor. The Indemnified Party shall permit the Contributor, at its option and expense, to assume the defense of any such claim by counsel selected by the Contributor and reasonably satisfactory to the Indemnified Party, and to settle or otherwise dispose of the same; provided, however, that the Indemnified Party may at all times participate in such defense at its expense; and provided further, however, that the Contributor shall not, in defense of any such claim, except with the prior written consent of the Indemnified Party in its sole and absolute discretion, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff in question to the Indemnified Party and its affiliates a release of all liabilities in respect of such claims, or that does not result only in the payment of money damages. If the Contributor shall fail to undertake such defense within 30 days after such notice, or within such shorter time as may be reasonable under the circumstances, then the Indemnified Party shall have the right to undertake the defense, compromise or settlement of such liability or claim on behalf of and for the account of the Contributor. 5.5 LIMITATIONS ON AND THRESHOLD FOR INDEMNIFICATION (a) No Contributor shall be liable under Sections 3.2, 3.3 or 5.3 hereof unless and until the aggregate amount recoverable from Indemnifying Parties under the indemnification provisions set forth in Section 5.3 exceeds $250,000; provided, however, that once the total amount recoverable from Indemnifying Parties exceeds $250,000 in the aggregate, the Contributor's obligation under Section 5.3 hereof shall be for the full amount of such obligation.
