                                                                    ------------



                            INDEMNIFICATION AGREEMENT

    THIS INDEMNIFICATION AGREEMENT (the "Agreement") is entered into as of
October 9, 1996, by and between Equity Office Properties Trust ("EOP"), a
Maryland real estate investment trust, and Samuel Zell (the "Indemnitee").

    WHEREAS, the Indemnitee is an officer or a member of the Board of Trustees
of EOP and in such capacity is performing a valuable service for EOP;

    WHEREAS, the law of EOP's state of organization permits EOP to enter into
contracts with its officers or members of its Board of Trustees with respect to
indemnification of such persons; and

    WHEREAS, to induce the Indemnitee to continue to provide services to EOP as
an officer or a member of the Board of Trustees, and to provide the Indemnitee
with specific contractual assurance that indemnification will be available to
the Indemnitee regardless of, among other things, any amendment to or revocation
of EOP's Amended and Restated Declaration of Trust ("Declaration of Trust"), or
any acquisition transaction relating to EOP, EOP desires to provide the
Indemnitee with protection against personal liability.

    NOW, THEREFORE, in consideration of the premises and the covenants contained
herein, EOP and the Indemnitee hereby agree as follows:

1.  DEFINITIONS.

    For purposes of this Agreement:

    (A)  "Change in Control" shall mean a change in the possession, directly or
         indirectly, of the power to direct or cause the direction of the
         management and policies of EOP, or any successor in interest thereto,
         whether through the ownership of voting securities, by contract or
         otherwise, including but not limited to a change which would be
         required to be reported under Item 6(e) of Schedule 14A of Regulation
         14A promulgated under the Securities Exchange Act of 1934 as in effect
         on the date hereof (the "Exchange Act") or as may otherwise be
         determined pursuant to a resolution of the Board of Trustees. A
         rebuttable presumption of a Change in Control shall be created by any
         of the following which first occur after the date hereof and EOP shall
         have the burden of proof to overcome such presumption:

         i.    the ability of any "Person" (as such term is defined in Sections
               13(d) and 14(d) of the Exchange Act) together with an "Affiliate"
               or "Associate" (as defined in Rule 12b-2 of the Exchange Act) or
               "Group" (within the meaning of Section 13(d)(3) of the Exchange
               Act) to exercise or direct the exercise of 20% or more of the
               combined voting power of all outstanding shares of beneficial
               interest of EOP in the election of its trustees ("Interested
               Party") (provided, however, "Interested Party" shall not include
               an agent, broker, nominee, custodian or trustee, solely in their
               capacity as such, for one or more persons who do not individually
               or as a group possess such power),

         ii.   during any period of two consecutive years, individuals who at
               the beginning of such period constitute the Board of Trustees of
               EOP cease for any reason to constitute at least a majority
               thereof, unless the election of each trustee who was not a
               trustee at the beginning of such period has been approved in
               advance by the trustees representing two-thirds of the trustees
               then in office who were the trustees at the beginning of the
               period,

         iii.  the approval of the shareholders of EOP of:

               (a)  a merger or consolidation of EOP with any Interested Party,

               (b)  any sale, lease, exchange, mortgage, pledge, transfer, or
                    other disposition, to or with any Interested Party in any
                    transaction or series of transactions, of EOP's assets or
                    the assets of any subsidiary of EOP having a market value
                    equal to 10% or more of the aggregate market value of all
                    assets of EOP determined on a consolidated basis, all
                    outstanding shares of beneficial interest of EOP, or the
                    earning power or net income of EOP, determined on a
                    consolidated basis,

               (c)  the issuance or transfer by EOP, or any subsidiary thereof,
                    to any Interested Party in any transaction or a series of
                    transactions, of capital securities with a value equal to 5%
                    or more of the aggregate market value of the then
                    outstanding voting shares of beneficial interest of EOP
                    other than the issuance or transfer of such shares of
                    beneficial interest to all EOP shareholders on a pro rata
                    basis,

               (d)  the adoption of any plan or proposal for the partial or
                    complete liquidation or dissolution of EOP proposed by an
                    Interested Party or pursuant to any agreement, arrangement
                    or understanding, whether or not in writing, with any
                    Interested Party, or

               (e)  any reclassification of securities, including, without
                    limitation, any share split, share dividend, or other
                    distributions of shares, or any reverse share split,
                    recapitalization of EOP, or any merger or consolidation of
                    EOP with any subsidiary thereof, or any other transaction
                    proposed by, or pursuant to, any agreement, arrangement, or
                    understanding, whether or not in writing, with any
                    Interested Party which has the effect, directly or
                    indirectly, of increasing the proportionate voting shares of
                    beneficial interest of EOP directly or indirectly owned by
                    any such Interested Party, or

         iv.   any receipt by any Interested Party, directly or indirectly, of
               any loans, advances, guarantees, pledges or other financial
               assistance, or any tax credits or other tax advantages provided
               by or through EOP other than the receipt of such advantages which
               are provided to all EOP shareholders on a pro rata basis.

    (B)  "Corporate Status" describes the status of a person who is or was a
         trustee, officer, employee, agent or fiduciary of EOP or of any other
         corporation, partnership, joint venture, trust, employee benefit plan
         or other enterprise (whether conducted for profit or not for profit)
         which such person is or was serving at the request of EOP.

    (C)  "Disinterested Trustee" means a trustee of EOP who is not and was not a
         party to the Proceeding (as hereinafter defined) in respect of which

    (D) "Effective Date" means the date of this Agreement as set forth above.

    (E)  "Expenses" shall include all attorneys and paralegals' fees, retainers,

    (F)  "Independent Counsel" means a law firm, or a member of a law firm, that
         is experienced in matters of corporation law and neither presently is,

         Indemnitee pursuant to paragraph 8 of this Agreement to enforce such
         Indemnitee's rights under this Agreement.

2.  INDEMNIFICATION--GENERAL

    The Indemnitee shall be entitled to the rights of indemnification provided
    in this paragraph 2 and under applicable law, the Amended and Restated
    Declaration of Trust, EOP's Bylaws, any agreement, a vote of shareholders or
    resolution of the Board of Trustees or otherwise if, by reason of such
    Indemnitee's Corporate Status, such Indemnitee is, or is threatened to be
    made, a party to any threatened, pending, or completed Proceeding, including
    a Proceeding by or in the right of EOP. Unless prohibited by paragraph 13
    hereof, the Indemnitee shall be indemnified against Expenses, judgments,
    penalties, fines, and settlement amounts actually and reasonably incurred by
    or on behalf of such Indemnitee in connection with such Proceeding or any
    claim, issue or matter therein.

3.  EXPENSES OF A SUCCESSFUL PARTY

    Without limiting the effect of any other provision of this Agreement, to the
    extent that the Indemnitee is, by reason of such Indemnitee's Corporate
    Status, a party to and is successful, on the merits or otherwise, in any
    Proceeding pursuant to a final non-appealable order, such Indemnitee shall
    be indemnified against all Expenses actually and reasonably incurred by or
    on behalf of such Indemnitee in connection therewith. If the Indemnitee is
    not wholly successful in such Proceeding pursuant to a final non-appealable
    order but is successful, on the merits or otherwise, as to one or more but
    less than all claims, issues, or matters in such Proceeding pursuant to a
    final non-appealable order, EOP shall indemnify the Indemnitee against all
    Expenses actually and reasonably incurred by or on behalf of 



                                       3



<PAGE>   4

    such Indemnitee in connection with each successfully resolved claim, issue
    or matter. For purposes of this paragraph and without limitation, the
    termination of any claim, issue or matter in such Proceeding by dismissal,
    with or without prejudice, shall be deemed to be a successful result as to
    such claim, issue or matter.

4.  WITNESS EXPENSES

    Notwithstanding any other provision of this Agreement, to the extent that
    the Indemnitee is, by reason of such Indemnitee's Corporate Status, a
    witness for any reason in any Proceeding to which such Indemnitee is not a
    party, such Indemnitee shall be indemnified against all Expenses actually
    and reasonably incurred by or on behalf of such Indemnitee in connection
    therewith.

5.  ADVANCES

    EOP shall advance all reasonable Expenses incurred by or on behalf of the
    Indemnitee in connection with any Proceeding within twenty (20) days after
    the receipt by EOP of a statement from the Indemnitee requesting such
    advance from time to time, whether prior to or after final disposition of
    such Proceeding. Such statement shall reasonably evidence the Expenses
    incurred by the Indemnitee and shall include or be preceded or accompanied
    by an undertaking by or on behalf of the Indemnitee to repay any Expenses
    advanced if it shall ultimately be determined that the Indemnitee is not
    entitled to be indemnified against such Expenses.

6.  DETERMINATION OF ENTITLEMENT TO INDEMNIFICATION

    (A)  To obtain indemnification under this Agreement, the Indemnitee shall
         submit to EOP a written request, including therewith such documentation
         and information reasonably necessary to determine whether and to what
         extent the Indemnitee is entitled to indemnification.

    (B)  Upon such written request pursuant to subparagraph 6(A), a
         determination with respect to the Indemnitee's entitlement thereto
         shall be made in the specific case: (i) if a Change in Control shall
         have occurred, by Independent Counsel in a written opinion to the Board
         of Trustees, a copy of which shall be delivered to the Indemnitee
         (unless the Indemnitee shall request that such determination be made by
         the Board of Trustees or the shareholders of EOP, in which case by the
         person or persons or in the manner provided in clauses (ii) or (iii) of
         this paragraph 6(B)); (ii) if a Change in Control shall not have
         occurred, (A) by the Board of Trustees by a majority vote of a quorum
         consisting of Disinterested Trustees, or (B) if a quorum of the Board
         of Trustees consisting of Disinterested Trustees is not obtainable, or,
         even if obtainable, if such quorum of Disinterested Trustees so
         directs, by Independent Counsel in a written opinion to the Board of
         Trustees, a copy of which shall be delivered to the Trustee, or (C) by
         the shareholders of EOP; or (iii) as provided in paragraph 7(B) of this
         Agreement. If it is so determined that the Indemnitee is entitled to
         indemnification, payment to the Indemnitee shall be made within ten
         (10) days after such determination.

    (C)  The Indemnitee shall cooperate with the person or entity making such
         determination with respect to the Indemnitee's entitlement to
         indemnification, including providing upon 

                                       4


<PAGE>   5

         reasonable advance request any documentation or information which is
         not privileged or otherwise protected from disclosure and which is
         reasonably available to the Indemnitee and reasonably necessary to such
         determination. Any costs or expenses (including attorneys' fees and
         disbursements) incurred by the Indemnitee in so cooperating shall be
         borne by EOP (irrespective of the determination as to the Indemnitee's
         entitlement to indemnification) and EOP hereby indemnifies and agrees
         to hold the Indemnitee's harmless therefrom.

    (D)  In the event the determination of entitlement to indemnification is to
         be made by Independent Counsel pursuant to paragraph 6(B) hereof, the
         Independent Counsel shall be selected as provided in this paragraph
         6(D). If a Change in Control shall not have occurred, the Independent
         Counsel shall be selected by the Board of Trustees, and EOP shall give
         written notice to the Indemnitee advising such Indemnitee of the
         identity of the Independent Counsel so selected. If a Change in Control
         shall have occurred, the Independent Counsel shall be selected by the
         Indemnitee (unless the Indemnitee shall request that such selection be
         made by the Board of Trustees, in which event the preceding sentence
         shall apply), and the Indemnitee shall give written notice to EOP
         advising it of the identity of the Independent Counsel so selected. In
         either event, the Indemnitee, or EOP, as the case may be, may, within
         seven (7) days after such written notice of selection shall have been
         given, deliver to EOP or to the Indemnitee, as the case may be, a
         written objection to such selection. Such objection may be asserted
         only on the grounds that the Independent Counsel so selected does not
         meet the requirements of "Independent Counsel" as defined in paragraph
         1 of this Agreement. If such written objection is made, the Independent
         Counsel so selected may not serve as Independent Counsel until a court
         has determined that such objection is without merit. If, within twenty
         (20) days after submission by the Indemnitee of a written request for
         indemnification pursuant to paragraph 6(A) hereof, no Independent
         Counsel shall have been selected or, if selected, shall have been
         objected to, either EOP or the Indemnitee may petition a court for
         resolution of any objection which shall have been made by EOP or the
         Indemnitee to the other's selection of Independent Counsel and/or for
         the appointment as Independent Counsel of a person selected by the
         court or by such other person as the court shall designate, and the
         person with respect to whom an objection is so resolved or the person
         so appointed shall act as Independent Counsel under paragraph 6(B)
         hereof. EOP shall pay all reasonable fees and expenses of Independent
         Counsel incurred in connection with acting pursuant to paragraph 6(B)
         hereof, and all reasonable fees and expenses incident to the selection
         of such Independent Counsel pursuant to this paragraph 6(D). In the
         event that a determination of entitlement to indemnification is to be
         made by Independent Counsel and such determination shall not have been
         made and delivered in a written opinion within ninety (90) days after
         the receipt by EOP of the Indemnitee's request in accordance with
         paragraph 6(A), upon the due commencement of any judicial proceeding in
         accordance with paragraph 8(A) of this Agreement, Independent Counsel
         shall be discharged and relieved of any further responsibility in such
         capacity.

7.  PRESUMPTIONS

    (A)  In making a determination with respect to entitlement or
         indemnification hereunder, the person or entity making such
         determination shall presume that the Indemnitee is 



                                       5


<PAGE>   6

         entitled to indemnification under this Agreement and EOP shall have the
         burden of proof to overcome such presumption.

    (B)  If the person or entity making the determination whether the Indemnitee
         is entitled to indemnification shall not have made a determination
         within sixty (60) days after receipt by EOP of the request therefor,
         the requisite determination of entitlement to indemnification shall be
         deemed to have been made and the Indemnitee shall be entitled to such
         indemnification, absent: (i) a misstatement by the Indemnitee of a
         material fact, or an omission of a material fact necessary to make the
         Indemnitee's statement not materially misleading, in connection with
         the request for indemnification, or (ii) a prohibition of such
         indemnification under applicable law. Such sixty (60)-day period may be
         extended for a reasonable time, not to exceed an additional thirty (30)
         days, if the person or entity making said determination in good faith
         requires additional time for the obtaining or evaluating of
         documentation and/or information relating thereto. The foregoing
         provisions of this paragraph 7(B) shall not apply: (i) if the
         determination of entitlement to indemnification is to be made by the
         shareholders and if within fifteen (15) days after receipt by EOP of
         the request for such determination the Board of Trustees resolves to
         submit such determination to the shareholders for consideration at an
         annual or special meeting thereof to be held within seventy-five (75)
         days after such receipt and such determination is made at such meeting,
         or (ii) if the determination of entitlement to indemnification is to be
         made by Independent Counsel pursuant to paragraph 6(B) of this
         Agreement.

    (C)  The termination of any Proceeding or of any claim, issue or matter
         therein, by judgment, order, settlement, or conviction, or upon a plea
         of nolo contendere or its equivalent, shall not (except as otherwise
         expressly provided in this Agreement) of itself adversely affect the
         right of the Indemnitee to indemnification.

8.  REMEDIES

    (A)  In the event that: (i) a determination is made that the Indemnitee is
         not entitled to indemnification under this Agreement, or (ii)
         advancement of Expenses is not timely made pursuant to this Agreement,
         or (iii) payment of indemnification due the Indemnitee under this
         Agreement is not timely made, the Indemnitee shall be entitled to an
         adjudication in an appropriate court of competent jurisdiction of such
         Indemnitee's entitlement to such indemnification or advancement of
         Expenses.

    (B)  In the event that a determination shall have been made pursuant to this
         Agreement that the Indemnitee is not entitled to indemnification, any
         judicial proceeding commenced pursuant to this paragraph 8 shall be
         conducted in all respects as a de novo trial, on the merits and the
         Indemnitee shall not be prejudiced by reason of that adverse
         determination. In any judicial proceeding or arbitration commenced
         pursuant to this paragraph 8, EOP shall have the burden of proving that
         the Indemnitee is not entitled to indemnification or advancement of
         Expenses, as the case may be.

    (C)  If a determination shall have been made or deemed to have been made
         pursuant to this Agreement that the Indemnitee is entitled to
         indemnification, EOP shall be bound by such determination in any
         judicial proceeding commenced pursuant to this paragraph 8, absent: (i)
         a misstatement by the Indemnitee of a material fact, or an 


                                       6



<PAGE>   7

         omission of a material fact necessary to make the Indemnitee's
         statement not materially misleading, in connection with the request for
         indemnification, or (ii) a prohibition of such indemnification under
         applicable law.

    (D)  EOP shall be precluded from asserting in any judicial proceeding
         commenced pursuant to this paragraph 8 that the procedures and
         presumptions of this Agreement are not valid, binding and enforceable
         and shall stipulate in any such court that EOP is bound by all the
         provisions of this Agreement.

    (E)  In the event that the Indemnitee, pursuant to this paragraph 8, seeks a
         judicial adjudication of such Indemnitee's rights under, or to recover
         damages for breach of, this Agreement, if successful in whole or in
         part, the Indemnitee shall be entitled to recover from EOP, and shall
         be indemnified by EOP against, any and all Expenses actually and
         reasonably incurred by such Indemnitee in such judicial adjudication.

9.  ESTABLISHMENT OF TRUST

    In the event of a Change in Control, EOP shall, upon written request by the
    Indemnitee, create a trust for the benefit of the Indemnitee ("Trust") and
    from time-to-time upon written request by the Indemnitee, shall fund such
    Trust in an amount sufficient to satisfy any and all Expenses, judgments,
    penalties, fines and settlement amounts actually and reasonably incurred by
    or on behalf of such Indemnitee or claimed, reasonably anticipated or
    proposed to be paid in accordance with the terms of this Agreement. The
    amount to be deposited in the Trust pursuant to the foregoing funding
    obligation shall be determined by Independent Counsel. The terms of the
    Trust shall provide that upon a Change in Control: (i) the Trust shall not
    be revoked or the principal thereof invaded, without the prior written
    consent of the Indemnitee, (ii) the trustee of the Trust ("Trustee") shall
    advance, within two business days of a request by the Indemnitee and in
    accordance with paragraph 5 of this Agreement, any and all Expenses to the
    Indemnitee, (iii) the Trust shall continue to be funded by EOP in accordance
    with the funding obligation set forth above, (iv) the Trustee shall promptly
    pay to the Indemnitee all amounts for which the Indemnitee shall be entitled
    to indemnification pursuant to this Agreement or otherwise, and (v) all
    unexpended funds in such Trust shall revert to EOP upon a final
    determination by Independent Counsel that the Indemnitee has been fully
    indemnified under the terms of this Agreement. The Trustee shall be chosen
    by the Indemnitee and agreed to by EOP. Nothing in this Section 9 shall
    relieve EOP of any of its obligations under this Agreement.

10. NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE SUBROGATION

    (A)  The rights of indemnification and to receive advancement of Expenses as
         provided by this Agreement shall not be deemed exclusive of any other
         rights to which the Indemnitee may at any time be entitled under
         applicable law, the Amended and Restated Declaration of Trust, EOP's
         Bylaws, any agreement, a vote of shareholders or a resolution of the
         Board of Trustees, or otherwise. No amendment, alteration or repeal of
         this Agreement or any provision hereof shall be effective as to the
         Indemnitee with respect to any action taken or omitted by the
         Indemnitee as a member of the Board of Trustees prior to such
         amendment, alteration or repeal.

    (B)  To the extent that EOP maintains an insurance policy or policies
         providing liability insurance for trustees of EOP, the Indemnitee shall
         be covered by such policy or policies in accordance with its or their
         terms to the maximum extent of the coverage available and upon any
         "Change in Control" EOP shall obtain continuation and/or "tail"
         coverage for the Indemnitee to the maximum extent obtainable at such
         time.

    (C)  In the event of any payment under this Agreement, EOP shall be
         subrogated to the extent of such payment to all of the rights of
         recovery of the Indemnitee, who shall execute all papers required and
         take all actions necessary to secure such rights, including execution
         of such documents as are necessary to enable EOP to bring suit to
         enforce such rights.

    (D)  EOP shall not be liable under this Agreement to make any payment of
         amounts otherwise indemnifiable hereunder if and to the extent that the
         Indemnitee has otherwise actually received such payment under any
         insurance policy, contract, agreement, or otherwise.

11. CONTINUATION OF INDEMNITY

    All agreements and obligations of EOP contained herein shall continue during
the period the Indemnitee is an officer or a member of the Board of Trustees of
EOP and shall continue thereafter so long as the Indemnitee shall be subject to
any threatened, pending or completed Proceeding by reason of such Indemnitee's
Corporate Status and during the period of statute of limitations for any act or
omission occurring during the Indemnitee's term of Corporate Status. No legal
action shall be brought and no cause of action shall be asserted by or on behalf
of EOP against the Indemnitee, the Indemnitee's spouse, heirs, executors or
personal or legal representatives after the expiration of two (2) years from the
date of accrual of such cause of action, and any claim or cause of action of EOP
shall be extinguished and deemed released unless asserted by the timely filing
of a legal action within such two (2) year period; provided, however, that if
any shorter period of limitations is otherwise applicable to any such cause of
action such shorter period shall govern. This Agreement shall be binding upon
EOP and its successors and assigns and shall inure to the benefit of the
Indemnitee and such Indemnitee's heirs, executors and administrators.

12. SEVERABILITY

    If any provision or provisions of this Agreement shall be held to be
invalid, illegal, or unenforceable for any reason whatsoever, (i) the validity,
legality, and enforceability of the remaining provisions of this Agreement
(including, without limitation, each portion of any paragraph of this Agreement
containing any such provision held to be invalid, illegal, or unenforceable,
that is not itself invalid, illegal, or unenforceable) shall not in any way be
affected or impaired thereby, and (ii) to the fullest extent possible, the
provisions of this Agreement (including, without limitation, each portion of any
paragraph of this Agreement containing any such provision held to be invalid,
illegal, or unenforceable, that is not itself invalid, illegal, or
unenforceable) shall be construed so as to give effect to the intent manifested
by the provisions held invalid, illegal, or unenforceable.
