                             CONTRIBUTION AGREEMENT

        THIS CONTRIBUTION AGREEMENT (including all exhibits, hereinafter
referred to as this "Agreement") is made and entered into as of November 11,
2002 by and between Maguire Properties, L.P., a Maryland limited partnership
(the "Operating Partnership"), and William Thomas Allen, an individual
("Contributor").

                                    RECITALS

        A. The Operating Partnership desires to consolidate the ownership of a
portfolio of office and other properties (the "Participating Properties")
located in Southern California and Texas through a series of transactions (the
"Formation Transactions") whereby the Operating Partnership will acquire either
(i) direct interests in the Participating Properties (the "Property Interests"),
or (ii) directly or indirectly, some or all of the interests in certain limited
partnerships, certain limited liability companies and certain other entities
(collectively, the "Participating Partnerships") which currently own directly or
indirectly the Participating Properties, or a combination of the foregoing.

        B. The Formation Transactions relate to the proposed initial public
offering (the "Public Offering") of the common stock of Maguire Properties,
Inc., a Maryland corporation (the "Company"), which will operate as a
self-administered and self-managed real estate investment trust ("REIT") within
the meaning of Section 856 of the Internal Revenue Code of 1986, as amended (the
"Code") and which is the sole general partner of the Operating Partnership.

        C. The owners of the Property Interests and the partners and members of
the Participating Partnerships will either transfer their unencumbered Property
Interests or unencumbered interests in the Participating Partnerships, as
applicable, to the Operating Partnership in exchange for cash or contribute such
unencumbered interests directly to the Operating Partnership in exchange for
units of limited partnership interest ("Partnership Units") in the Operating
Partnership.

        D. Pursuant to that certain letter agreement, dated as of January 1,
1996, among Robert F. Maguire III, Contributor, and Maguire Partners
Development, Ltd. (formerly Maguire/Thomas Partners Development, Ltd.) and other
side letters and ancillary agreements entered into in connection therewith (the
"Executive Equity Agreements"), Contributor owns interests in certain of the
Participating Partnerships as set forth on Exhibit A (each, a "Partnership", and
collectively, the "Partnerships") which Partnerships own directly or indirectly
interests in certain of the Participating Properties or "Projects" (as defined
in the Executive Equity Agreements) as set forth on Exhibit A (each, a
"Property" and together the "Properties"). As used herein, "Partnership
Agreement" means the respective partnership agreement, limited liability company
agreement or membership agreement, as applicable, under which each Partnership
was formed (including all amendments or restatements).





                                       1
<PAGE>

        E. Contributor may also participate in that certain Equity Participation
Program of Maguire Thomas Partners Development Ltd. effective as of January 1,
1989, and the Participation Acknowledgement Agreement executed by Contributor in
connection therewith (the "Equity Participation Program"). In consideration of
this Agreement, Contributor is releasing his rights, claims and interests, if
any, in, to and under, the Equity Participation Program.

        F. Contributor desires to, and the Operating Partnership desires
Contributor to, contribute to the Operating Partnership, all of its right, title
and interest, free and clear of all Liens (as defined in Exhibit D), as a
partner or member in each of the Partnerships, including, without limitation,
all of its voting rights and interests in the capital, profits and losses of the
Partnerships or any property distributable therefrom, constituting all of its
interests in and to the Partnerships (such right, title and interest in and to
the Partnerships are hereinafter collectively referred to as the "Partnership
Interests"), in exchange for either Partnership Units or cash, on the terms and
subject to the conditions set forth herein.

        G. Contributor acknowledges that the Operating Partnership may decide
that, rather than acquiring all of the direct and indirect interests in the
entity that owns a certain Property or acquiring a Partnership Interest by
direct transfer, it is more desirable for the Operating Partnership to acquire a
particular Property by a direct contribution of such Property from the
Partnership that owns such Property (a "Direct Contribution"), or by a merger of
the Contributor (if Contributor is an entity) or a Partnership with and into the
Company, the Operating Partnership or an affiliate of either of them (a
"Merger"), or to divide a Partnership into more than one partnership to
facilitate the Formation Transactions (a "Division"); and Contributor desires to
give the Operating Partnership the right, in the Operating Partnership's sole
discretion, to engage in any Direct Contribution, Merger or Division on the
terms and conditions described herein without the need to seek any further
consent or action of the Contributor, and will give hereby an irrevocable power
of attorney as set forth in Article 6 hereof and irrevocable consents as set
forth in Section 5.4 hereof, subject to the terms and conditions of this
Agreement.

        H. The parties acknowledge that the Operating Partnership's acquisition
of the Partnership Interests and Contributor's contribution or sale of its
Partnership Interests is in connection with and are subject to the consummation
of the Formation Transactions and the Public Offering. It is understood that the
Operating Partnership may acquire interests in additional properties with the
proceeds of the Public Offering.

        NOW, THEREFORE, for and in consideration of the foregoing premises, and
the mutual undertakings set forth below, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:



                                       2

                               TERMS OF AGREEMENT

                                   ARTICLE 1.
                      CONTRIBUTION OF PARTNERSHIP INTERESTS
                   AND EXCHANGE FOR PARTNERSHIP UNITS OR CASH

      Section 1.1 Contribution Transaction.

          At the Closing (as defined in Section 2.2 herein) and subject to the
  terms and conditions contained in this Agreement, Contributor shall
  contribute, transfer, assign, convey and deliver to the Operating Partnership,
  absolutely and unconditionally and free and clear of all Liens, all of its
  Partnership Interests, including all of Contributor's rights and interests to
  the Partnerships or any Projects under the Executive Equity Agreement (which
  are not the subject of the RFM Option Agreement) and all rights to
  indemnification in favor of the Contributor under the agreements pursuant to
  which Contributor or its affiliates acquired the Partnership Interests
  transferred pursuant to this Agreement. The contribution of Contributor's
  Partnership Interests shall be evidenced by a Contribution and Assumption
  Agreement in substantially the form of Exhibit B attached hereto. Furthermore,
  Contributor shall execute or shall cause each of its individual constituent
  partners and/or members (as applicable) to execute and have duly acknowledged
  an individual quitclaim deed for each Property in the form of Exhibit C
  quitclaiming to the Operating Partnership any direct or indirect ownership
  interest in and to the Properties. The parties shall take such additional
  actions and execute such additional documentation as may be required by each
  relevant Partnership Agreement and the Amended and Restated Agreement of
  Limited Partnership of the Operating Partnership (the "OP Agreement") or as
  requested in the reasonable judgment of counsel to the Operating Partnership
  in order to effect the transactions contemplated hereby.

      Section 1.2 Consideration and Exchange of Partnership Units.

          Subject to Section 1.3, the Operating Partnership shall, in exchange
  for the Partnership Interests, transfer to Contributor the number of
  Partnership Units having a value, based on one Partnership Unit being equal in
  value to the Public Offering price for one share of the Company's common
  stock, equal to the value of Contributor's Total Consideration indicated on
  Exhibit A. The transfer of the Partnership Units to Contributor shall be
  evidenced by either an amendment (the "Amendment") to the OP Agreement or by
  certificates relating to such Partnership Units (the "Certificates") in either
  case, as determined by the Operating Partnership, in such form as shall be
  reasonably acceptable to Contributor. The parties shall take such additional
  actions and execute such additional documentation as may be required by the
  relevant Partnership Agreements and the OP Agreement in order to effect the
  transactions contemplated hereby. Notwithstanding the foregoing, the Operating
  Partnership reserves the right, at its option, to be exercised in the
  Operating Partnership's sole and absolute discretion, to acquire the
  Partnership Interests for a cash payment, equal to the value of Contributor's
  Total Consideration indicated on Exhibit A, effectuated by wire-transfer at
  Closing in lieu of the transfer of Partnership Units (the "Cash-Out Option").
  If the Operating Partnership elects to exercise this Cash-Out Option, it shall
  notify Contributor at least one day prior to the Closing Date of its intention
  to pay Contributor cash at Closing.



                                       3
<PAGE>

      Section 1.3 Adjusted Consideration.

          The Operating Partnership reserves the right not to acquire any
  particular interest that constitutes part of the Partnership Interests, if in
  good faith the Operating Partnership determines that the ownership of such
  interest or the underlying Property would be inappropriate for the Operating
  Partnership. Contributor acknowledges that, in such event, Contributor's Total
  Consideration as calculated based on the formula on Exhibit A may be adversely
  affected.

          The risk of loss relating to Contributor's Partnership Interests and
  the underlying Properties prior to Closing shall be borne by Contributor. If,
  prior to the Closing, any Property is destroyed or damaged by fire or other
  casualty, then the Operating Partnership may, at its option, determine not to
  acquire the particular interest in the Partnership that directly or indirectly
  owns the Property that has been destroyed or damaged. After the occurrence of
  any such casualty affecting a Property, the Operating Partnership may also, at
  its option, elect to (a) acquire the Contributor's particular interest in any
  such Partnership that directly or indirectly owns the affected Property, (b)
  direct Contributor to pay or cause to be paid to the Operating Partnership any
  sums collected under any policies of insurance relating to such casualty and
  otherwise assign to the Operating Partnership all rights to collect such sums
  as may then be uncollected, and (c) adjust or settle any insurance claim.
  Under such circumstances, the Contributor acknowledges that the Total
  Consideration will likely be adversely affected based on the formula set forth
  on Exhibit A. Insurance on the transferred Partnership Interests shall be
  assigned to the Operating Partnership at the Closing.

      Section 1.4 Tax Treatment of Transaction.

          To the extent the transfer, assignment and exchange effectuated
  pursuant to this Agreement occurs in exchange for (a) Partnership Units (i.e.,
  the Cash-Out -- Option is not exercised), such transaction shall constitute a
  "Capital Contribution" to the Operating Partnership pursuant to Article 4 of
  the OP Agreement and is intended to be governed by Section 721(a) of the Code;
  or (b) cash (i.e., the Cash-Out Option is exercised), such transaction shall
  constitute a sale by Contributor (or any other transferor as provided
  hereunder) to the Operating Partnership with the tax consequences set forth in
  Section 741 of the Code; and Contributor (or such other transferor) hereby
  consents to such treatment. In the event the Cash-Out Option is exercised, the
  Operating Partnership agrees to pay all transfer taxes arising from the sale
  of Contributor's Partnership Interests to the Operating Partnership.

      Section 1.5 Allocation of Total Consideration.

          The Total Consideration shall be allocated in a manner reasonably
  determined by the Operating Partnership. The Operating Partnership and
  Contributor agree to (i) be bound by the allocation, (ii) act in accordance
  with the allocation in the preparation of financial statements and filing of
  all tax returns and in the course of any tax audit, tax review or tax
  litigation relating thereto and (iii) take no position and cause their
  affiliates to take no position inconsistent with the allocation for income tax
  purposes.



                                       4
<PAGE>

      Section 1.6 Term of Agreement.

          If the Closing does not occur by June 30, 2003 (the "Termination
  Date"), this Agreement shall be deemed terminated and shall be of no further
  force and effect and neither the Operating Partnership nor the Contributor
  shall have any further obligations hereunder except as specifically set forth
  herein.

      Section 1.7 Final Year Allocations.

          To the extent a Partnership Agreement does not provide for final year
  tax allocations, the parties hereto agree to use the "interim closing of the
  books" method as provided in Section 706 of the Code to allocate income and
  loss for the year.

                                   ARTICLE 2.
                                     CLOSING

      Section 2.1 Conditions Precedent.

          The effectiveness of the Company's registration statement to be filed

authority or instrumentality that prohibits the



                                       5
<PAGE>

consummation of the transactions contemplated hereby, and no litigation or
governmental proceeding seeking such an order shall be pending or threatened;

        (f) There shall not have occurred between the date hereof and the
Closing Date any material adverse change in any of the assets, business,
financial condition, results of operation or prospects of each Partnership;

        (g) The contribution of the Partnership Interests and equity interests
in the other Participating Partnerships is approved by their respective partners
and members to the extent such approval is required by the applicable limited
partnership agreements and limited liability company operating agreements; and

        (h) Contributor shall have entered into an option agreement with Robert
F. Maguire III granting Robert F. Maguire III an option to acquire for cash
certain properties, partnership interests and any other rights and interests
under the Executive Equity Agreements or the Equity Participation Program not
included in the Properties or Partnerships subject to this Agreement (the "RFM
Option Agreement").

          The foregoing conditions may be waived by the Operating Partnership in
  its sole and absolute discretion.

          The obligation of the Contributor to effect the transactions
  contemplated hereby is subject to the following condition precedent: (i) no
  order, statute, rule, regulation, executive order, injunction, stay, decree or
  restraining order shall have been enacted, entered, promulgated or enforced by
  any court of competent jurisdiction or governmental or regulatory authority or
  instrumentality that prohibits the consummation of the transactions
  contemplated hereby; and (ii) the concurrent closing of the transactions under
  the RFM Option Agreement.

      Section 2.2 Time and Place.

          The date, time and place of the transactions contemplated hereunder
  shall be the day the Operating Partnership receives the proceeds from the
  Public Offering from the underwriter(s), at 10:00 a.m. in the office of Latham
  & Watkins, 633 West Fifth Street, Sixth Floor, Los Angeles, California (the
  "Closing" or "Closing Date"). The transfers described in Article 1 of this
  Agreement, all closing deliveries and the consummation of the Public Offering
  shall be deemed concurrent for all purposes.

      Section 2.3 Closing Deliveries.

      Section 3.1 Representations and Warranties of the Operating Partnership.

          The Operating Partnership hereby represents and warrants to and
  covenants with Contributor that:

        (a) Organization; Authority. The Operating Partnership has been duly
formed and is validly existing under the laws of the jurisdiction of its

all necessary action of the Operating Partnership. This Agreement and each
agreement, document and instrument executed and delivered by or on behalf of the

Offering and the consummation of the Formation Transactions, no consent, waiver,
approval or authorization of any third party or governmental authority or agency

        (d) The covenants in this Section 4.1 shall not apply to the actions or
conduct of Contributor taken in his capacity as an employee of Maguire Partners
Development, Ltd. (or its affiliate) provided such actions or conduct are
performed within the course and scope of Contributor's employment and with
proper authority.

<PAGE>

        MATERIALLY AFFECTED THE SETTLEMENT WITH THE
        DEBTOR.

        Section 5.4 Waiver of Rights Under Partnership Agreements, the Executive
Equity Agreements and the Equity Participation Program; Consents With Respect to
Partnership Interests.

          (a) As of the Closing, Contributor waives and relinquishes all rights
and benefits otherwise afforded to Contributor under any Partnership Agreement
or the Executive Equity Agreements including, without limitation, any rights of
appraisal, rights of first offer or first refusal, buy/sell agreements, and any
right to consent to or approve of the sale or contribution by the other partners
or members of each Partnership of their Partnership Interests to the Operating
Partnership, the Company or any direct or indirect subsidiary thereof or any
sale of such Partnership Interests to Robert F. Maguire III (or his designee).
Contributor acknowledges that the agreements contained herein and the
transactions contemplated hereby and any actions taken in contemplation of the
transactions contemplated hereby may conflict with, and may not have been
contemplated by, certain Partnership Agreements or other agreements including
the Executive Equity Agreements among one or more holders of such Partnership
Interests or one or more of the partners of any such Partnership. With respect
to each Partnership and each Property in which a Partnership Interest of
Contributor represents a direct or indirect interest, Contributor expressly
gives all Consents (and any consents necessary to authorize the proper parties
in interest to give all Consents) and Waivers necessary or desirable to (i)
facilitate any Conveyance Action relating to such Partnership or Property or
Project under the Executive Equity Agreements, (ii) cause the Partnership to
have authority to transfer the Partnership Interests or Properties or Project
under the Executive Equity Agreements to the Operating Partnership, and (iii)
allow Contributor to receive Partnership Units and/or cash directly from the
Partnership if the Partnership or one or more of the Partnership's subsidiaries
transfers assets or interests directly to the Operating Partnership (rather than
the Contributor contributing its or his Partnership Interests hereunder) and to
reduce the consideration otherwise payable by the Operating Partnership
hereunder as a result of such direct transfer by the Partnership or its
subsidiaries on account of Contributor receiving any amount reduced hereunder
from such Partnership or its subsidiaries making such direct transfer. In
addition, if the transaction occurs this Agreement shall be deemed to be an
amendment to any Partnership Agreement and the Executive Equity Agreements to
the extent the terms herein conflict with the terms thereof, including without
limitation, terms with respect to allocations, distributions and the like. In
the event the transactions contemplated by this Agreement do not occur, nothing
in this Agreement or the RFM Option Agreement shall be deemed to or construed as
an amendment or modification of, or commitment of any kind to amend or modify,
the Partnership Agreements, Executive Equity Agreements or the Equity
Participation Program, all of which shall remain in full force and effect
without modification.

          (b) As used herein, the term "Conveyance Action" means, with respect
to any Partnership having a direct or indirect ownership interest in any
Property Interest or Project, (i) the transfer, conveyance or agreement to
convey by a partner thereof or by any holder of an indirect interest therein
(whether or not such partner or holder is the Contributor hereunder) directly,
by Direct Contribution, Merger, Division or otherwise of its direct or indirect
interest in such Partnership or Property or Project to the Operating Partnership
or the Company or (ii) the entering into by any such partner or holder any
agreement relating to (x) the formation of the Operating Partnership or the
Company, or (y) the direct or indirect acquisition by the Operating Partnership
or



                                       12
<PAGE>

the Company of any such direct or indirect interest or (iii) the taking by any
such partner or holder of any action necessary or desirable to facilitate any of
the foregoing, including, without limitation, the following (provided that the
same are taken in furtherance of the foregoing): any sale or distribution to any
person of a direct or indirect interest in such Partnership or Property or
Project, the entering into any agreement with any person that grants to such
person the right to purchase a direct or indirect interest in such Partnership
or Property or Project, and the giving of the Consents and Waivers contained in
this Section or consents or waivers similar thereto in form or purpose.

          (c) As used herein, the term "Consents" means, with respect to any
Partnership or Property or Project, any consent necessary or desirable under any
Partnership Agreement, the Executive Equity Agreements, the Equity Participation
Program or any other agreement among all or any of the holders of interests
therein or any other agreement relating thereto or referred to therein (i) to
cause the Partnership to have authority to permit any and all Conveyance Actions
relating to such Partnership or the Property held by such Partnership, or to
amend any such Partnership Agreement, Executive Equity Agreements and/or other
agreements so that no provision thereof prohibits, restricts, impairs or
interferes with any Conveyance Action (such amendments to include, without
limitation, the deletion of provisions which cause a default under such
agreement if interests therein are transferred for cash), (ii) to admit the
Operating Partnership as a substitute limited partner or general partner of such
Partnership upon the Operating Partnership's acquisition of a limited or general
Partnership Interest therein, respectively, and to adopt such amendment as is
necessary or desirable to effect such admission, (iii) to adopt any amendment to
such Partnership Agreement as may be necessary or desirable to facilitate the
transactions contemplated herein, either simultaneously with or immediately
prior to the acquisition of any interest therein, (iv) to continue such
Partnership following the transfer of interest therein to the Operating
Partnership, and (v) to satisfy any requirement of any third party, Title
Company, or governmental authority with respect to the Conveyance Actions.

          (d) As used herein, the term "Waivers" means, with respect to a
Partnership or a Property or a Project of which a Partnership Interest of
Contributor represents a direct or indirect interest, the waiving of any and all
rights that Contributor may have with respect to, and (to the extent possible)
that any other person may have with respect to, or that may accrue to
Contributor or other person upon the occurrence of, a Conveyance Action relating
to such Partnership or Property or Project, including, but not limited to, the
following rights: rights of notice, rights to response periods, rights to
purchase the direct or indirect interests of another partner in such Partnership
or Property or Project or to sell Contributor's or other person's direct or
indirect interest therein to another partner, rights to sell Contributor's or
other person's direct or indirect interest therein at a price other than as
provided herein, or rights to prohibit, limit, invalidate, otherwise restrict or
impair any such Conveyance Action or to cause a termination or dissolution of
such Partnership because of such Conveyance Action. Contributor further
covenants that Contributor will take no action to enjoin, or seek damages
resulting from, any Conveyance Action by any holder of a direct or indirect
interest in a Partnership or a Property or a Project in which a Partnership
Interest of Contributor represents a direct or indirect interest.

          (e) The Waivers and Consents contained in this Section shall terminate
upon the termination of this Agreement, except as to transactions completed
hereunder prior to termination.

                                   ARTICLE 6.
                                POWER OF ATTORNEY

      Section 6.1 Grant of Power of Attorney.

        Contributor hereby irrevocably appoints the Operating Partnership (or
its designee) and any successor thereof from time to time (such Operating
Partnership or designee or any such successor of any of them acting in his, her
or its capacity as attorney-in-fact pursuant hereto, the "Attorney-In-Fact") as
the true and lawful attorney-in-fact and agent of Contributor, to act in the
name, place and stead of Contributor to make, execute, acknowledge and deliver
all such other contracts, orders, receipts, notices, requests, instructions,
certificates, consents, letters and other writings (including without limitation
the execution of any Closing Documents or other documents relating to the
acquisition by the Operating Partnership of Contributor's Partnership Interests
including, but not limited to, any registration rights agreements and any
lock-up agreements), to provide information to the Securities and Exchange
Commission and others about the transactions contemplated hereby and, in
general, to do all things and to take all actions which the Attorney-in-Fact in
its sole discretion may consider necessary or proper in connection with or to
carry out the transactions contemplated by this Agreement, as fully as could
Contributor if personally present and acting (the "Power of Attorney"). Further,
Contributor hereby grants to Attorney-in-Fact a proxy (the "Proxy") to vote
Contributor's Partnership Interests on any matter related to the Formation
Transactions presented to any of the Partnerships' partners for a vote,
including, but not limited to, the transfer of interests in any Partnership by
the other partners.

        Each of the Power of Attorney and Proxy and all authority granted hereby
shall be coupled with an interest and therefore shall be irrevocable and shall
not be terminated by any act of Contributor, by operation of law or by the
occurrence of any other event or events, and if any other such act or events
shall occur before the completion of the transactions contemplated by this
Agreement, the Attorney-in-Fact shall nevertheless be authorized and directed to
complete all such transactions as if such other act or events had not occurred
and regardless of notice thereof. Contributor agrees that, at the request of
Operating Partnership it will promptly execute and deliver to the Operating
Partnership a separate power of attorney and proxy on the same terms set forth
in this Article 6, such execution to be witnessed and notarized. Contributor
hereby authorizes the reliance of third parties on each of the Power of Attorney
and Proxy.

        Contributor acknowledges that the Operating Partnership has, and any
designee or successor thereof acting as Attorney-in-Fact may have, an economic
interest in the transactions contemplated by this Agreement.

        The Power of Attorney contained in this Section 6.1 shall expire on the
earlier to occur of the fourth anniversary of the Closing or the termination of
this Agreement. Notwithstanding anything to the contrary contained herein, the
Attorney-in-Fact shall not materially expand Contributor's obligations,
liabilities, representations or warranties beyond those contemplated by this
Agreement, the other documents and agreements contemplated hereby, or as
required to transfer the Partnership Interests to the Operating Partnership, and
the Operating Partnership shall hold the Contributor harmless to the extent of
any such expansion; provided, however, the Operating Partnership shall have no
liability with respect to Contributor's



                                       14
<PAGE>

tax obligations and the Operating Partnership makes no representations or
warranties with respect to the tax consequences to Contributor of the
transactions contemplated herein.

      Section 6.2 Limitation on Liability.

        It is understood that the Attorney-in-Fact assumes no responsibility or
liability to any person by virtue of the Power of Attorney or Proxy granted by
Contributor hereby. The Attorney-in-Fact makes no representations with respect
to and shall have no responsibility for the Formation Transactions or the Public
Offering, or the acquisition of the Partnership Interests by the Operating
Partnership and shall not be liable for any error or judgment or for any act
done or omitted or for any mistake of fact or law except for its own gross
negligence or bad faith. Contributor agrees that the Attorney-in-Fact may
consult with counsel of its own choice (who may be counsel for the Operating
Partnership or its successors or affiliates), and it shall have full and
complete authorization and protection for any action taken or suffered by it
hereunder in good faith and in accordance with the opinion of such counsel. It
is understood that the Attorney-in-Fact may, without breaching any express or
implied obligation to Contributor hereunder, release, amend or modify any other
power of attorney or proxy granted by any other person under any related
agreement.

      Section 6.3 Ratification; Third Party Reliance.

        Contributor hereby ratifies and confirms that the Attorney-in-Fact shall
lawfully do or cause to be done by virtue of the exercise of the powers granted
unto him by Contributor under this Article 6, and Contributor authorizes the
reliance of third parties on this Power of Attorney and waives its rights, if
any, as against any such third party for its reliance hereon.

                                   ARTICLE 7.
                                  MISCELLANEOUS

      Section 7.1 Dispute Resolution.

        The parties hereby agree that, in order to obtain prompt and expeditious
resolution of any disputes under this Agreement, each claim, dispute or
controversy of whatever nature, arising out of, in connection with, or in
relation to the interpretation, performance or breach of this Agreement (or any
other agreement contemplated by or related to this Agreement or any other
agreement between the parties), including without limitation any claim based on
contract, tort or statute, or the arbitrability of any claim hereunder (an
"Arbitrable Claim"), shall be settled by final and binding arbitration conducted
in Los Angeles, California. The arbitrability of any Arbitrable Claims under
this Agreement shall be resolved in accordance with a two-step dispute
resolution process administered by Judicial Arbitration & Mediation Services,
Inc. ("JAMS") involving, first, mediation before a retired judge from the JAMS
panel, followed, if necessary, by final and binding arbitration before the same,
or if requested by either party, another JAMS panelist. Such dispute resolution
process shall be confidential and shall be conducted in accordance with
California Evidence Code Section 1119.

          (i) Mediation. In the event any Arbitrable Claim is not resolved by an
  informal negotiation between the parties within fifteen (15) days after either
  party receives written notice that a Arbitrable Claim exists, the matter shall
  be referred to the



                                       15
<PAGE>

  Los Angeles, California office of JAMS, or any other office agreed to by the
  parties, for an informal, non-binding mediation consisting of one or more
  conferences between the parties in which a retired judge will seek to guide
  the parties to a resolution of the Arbitrable Claims. The parties shall select
  a mutually acceptable neutral arbitrator from among the JAMS panel of
  mediators. In the event the parties cannot agree on a mediator, the
  Administrator of JAMS will appoint a mediator. The mediation process shall
  continue until the earliest to occur of the following: (i) the Arbitrable
  Claims are resolved, (ii) the mediator makes a finding that there is no
  possibility of resolution through mediation, or (iii) thirty (30) days have
  elapsed since the Arbitrable Claim was first scheduled for mediation.

          (ii) Arbitration. Should any Arbitrable Claims remain after the
  completion of the mediation process described above, the parties agree to
  submit all remaining Arbitrable Claims to final and binding arbitration
  administered by JAMS in accordance with the then existing JAMS Arbitration
  Rules. Neither party nor the arbitrator shall disclose the existence, content,
  or results of any arbitration hereunder without the prior written consent of
  all parties. Except as provided herein, the California Arbitration Act shall
  govern the interpretation, enforcement and all proceedings pursuant to this
  subparagraph. The arbitrator is without jurisdiction to apply any substantive
  law other than the laws selected or otherwise expressly provided in this
  Agreement. The arbitrator shall render an award and a written, reasoned
  opinion in support thereof. Such award may include reasonable attorneys' fees
  to the prevailing party. Judgment upon the award may be entered in any court
  having jurisdiction thereof.

          (iii) Costs. The parties shall bear their respective costs incurred in
  connection with the procedures described in this Section 7.1, except that the
  parties shall equally share the fees and expenses of the mediator or
  arbitrator and the costs of the facility for the hearing.

          (iv) Survivability. This dispute resolution process shall survive the
  termination of this Agreement. The parties expressly acknowledge that by
  signing this Agreement, they are giving up their respective right to a jury
  trial.

      Section 7.2 Further Assurances.

        Contributor shall take such other actions and execute such additional
documents following the Closing as the Operating Partnership may reasonably
request in order to effect the transactions contemplated hereby, except that
Contributor shall not be obligated to take any action or execute any document if
the additional actions or documents impose additional liabilities, obligations,
covenants, responsibilities, representations or warranties on the Contributor
which are not contemplated by this Agreement or reasonably inferable by the
terms herein.

      Section 7.3 Counterparts.

        This Agreement may be executed in one or more counterparts, each of

* All or a portion of this Partnership Interest was acquired via a distribution
of assets from Maguire/Thomas Partners - Master Investments, a California

The "Total Consideration" for the above Properties and Partnerships is equal to
the sum of:

(a)      (0.025) X (EV - (PIPE + PO/A + MTPD +TCR)); provided, that in no event
shall the preceding amount be less than $1,000,000 (the "Minimum
Consideration"), nor more than Contributor's "Distribution Maximum" under the
Executive Equity Agreements (as reduced by $422,813 to account for all
distributions to Contributor from and after January 1, 1996 on account of the
Retained Interests (as defined below))

PLUS

(b)      $482,230 together with interest thereon at the rate of six percent (6%)
per annum from July 1, 2002 through the Closing to account of Contributor's
Retained Interests.

WHERE:

EV = Enterprise Value;
PIPE = Pre-Public Offering Indebtedness and Preferred Equity;
PO/A = Project Overhead/Advances;
MTPD = MTP-D Net Proceeds; and
TCR = Transaction Costs and Reserves.

For purposes of the foregoing, the following terms shall have the following
meanings:

prior payments by Robert F. Maguire III on the "Development Term Loan" (as
defined in the Executive Equity Agreements), including accrued interest from the
respective dates of payment at two percent (2%) per annum over the reference
rate announced from time to time by Bank of America, all as determined as of the
Closing Date. The parties agree that as of June 30, 2002, the Development Term
Loan Reimbursement Amount (including accrued interest) was equal to $27,288,191.

"Enterprise Value" shall mean the sum, as of the Closing Date, of (a) the
product of (i) all issued and outstanding Common Stock and Partnership Units
(other than unvested Common Stock and Partnership Units issued pursuant to
employee incentive programs and any Common Stock issued or issuable pursuant to
any over-allotment option of the underwriters) and (ii) the initial price per
share of Common Stock in the Public Offering PLUS (b) the amount of Indebtedness
and Preferred Equity of the Company, the Operating Partnership, their
subsidiaries and their affiliates holding direct or indirect equity interests in
the Participating Properties outstanding upon the Closing, after application of
the proceeds of the Public Offering. "Enterprise Value" shall be calculated
without duplication for any Partnership Units, Preferred Equity or Indebtedness
of the Operating Partnership or its subsidiaries issued to the Company and
intended to mirror any outstanding Common Stock, Preferred Equity or
Indebtedness of the Company.

"Indebtedness" shall mean any indebtedness of a specified Person, whether or not
contingent, secured, senior, mezzanine or subordinated: (i) in respect of
borrowed money; (ii) evidenced by bonds, notes, debentures or similar
instruments; (iii) representing capital lease obligations; or (iv) representing
the unpaid balance of the purchase price of any property or asset or any direct
or indirect ownership interest in any Participating Property, except any such
balance that constitutes an accrued expense or trade payable.

                               Exhibit A, Page 3

<PAGE>

"MTP-D Net Proceeds," notwithstanding the meaning ascribed to that term in the
Executive Equity Agreements, shall mean $30,000,000 for purposes of the
foregoing determination.

"Preferred Equity" shall means all preferred equity interests of a specified
Person, including without limitation all capital stock, membership interests or
partnership interests enjoying priority in dividends, distributions,
liquidation, voting rights or otherwise.

"Pre-Public Offering Indebtedness and Preferred Equity" shall mean the total of
(a) all outstanding Indebtedness (including, without limitation, any unpaid
purchase price payable to Arai Pasadena Limited Partnership, ATC Realty, Inc.,
ATC Realty Seventeen, Inc. or to existing partners or members holding direct or
indirect ownership interests or management rights with respect to the
Participating Properties (other than to "Participation Partners" (as defined in
the Executive Equity Agreements)) (including the ownership interests of Gibson
Dunn & Crutcher Revocable Retirement Trust, MAC-WFT, Inc., Crocker Properties,
Inc., Crocker Grande, Inc. and Cushman-Pasadena Ltd.)) and Preferred Equity
relating to the Participating Properties, the Participating Partnerships and
LLCs or the other assets and liabilities contributed to the Company, the
Operating Partnership, their subsidiaries or their affiliates holding direct or
indirect interests in the Participating Properties, determined immediately prior
to the Closing Date, together with (b) all accrued or accumulated interest,
dividends or distributions and all yield or spread maintenance payments,
prepayment penalties, exit fees, and other amounts, costs or expenses payable on
account of the repayment or assumption of any such Indebtedness and the
redemption or prepayment of any such Preferred Equity in connection with the
Formation Transactions or the Closing, less (c) the amount of established
project-level reserves relating to the outstanding Indebtedness and Preferred
Equity described in (a) and (b) of this definition that are not to be held as
reserves after the Closing.

"Project/Overhead Advances" shall have the meaning ascribed to that term in the
Executive Equity Agreements and shall include the interest accrual (two percent
(2%) per annum over the reference rate announced from time to time by Bank of
America) contemplated under the Executive Equity Agreement, determined as of the
Closing Date; provided, however, that the Project/Overhead Advances will be
reduced by the difference between (a) the MTP-D Net Proceeds, and (b) the
Development Term Loan Reimbursement Amount. The parties agree that as of June
30, 2002, the "Project/Overhead Advances" (including accrued interest but not
including the difference between the MTP-D Net Proceeds and the Development Term
Loan Reimbursement Amount) were equal to $57,205,777.

"Retained Interests" shall have the meaning ascribed to that term in the
Amendment to Employment Agreement of William Thomas Allen, dated as of February
11, 1998, between Contributor and Maguire Partners Development, Ltd.

"Transaction Costs and Reserves" shall mean the (a) outstanding third party
payables of the Company, the Operating Partnership, Maguire Properties
Development Ltd. or their subsidiaries or affiliates paid in connection with the
Formation Transactions or the Public Offering, including a reserve not to exceed
$3,500,000 against potential liabilities to IBM in connection with the sale of
MGM Plaza and compensation payable under existing employment or consulting
agreements (including compensation payable to Jeffrey Friedman, but not
including compensation payable to "Partners" of Maguire Partners Development
Ltd. or to Peggi Moretti or Mark Lammas ), but excluding the repayment of the
outstanding balance of the facility from United California Bank (formerly Sanwa
Bank) or payments to other Participation Partners on account of ownership
interests in the Properties, (b) third party fees and expenses incurred by the
Company, the Operating Partnership, Maguire Properties Development Ltd. or their

and filing and qualification fees, (c) third party fees, costs, and reserves
associated with all third party Indebtedness or Preferred Equity obtained by the
Company, the Operating Partnership, Maguire Properties Development Ltd. or their
subsidiaries or affiliates in contemplation of the Formation Transactions or the
Public Offering and (d) the amount of working capital reserves established by
the Company and the Operating Partnership on the Closing Date. The foregoing
Transaction Costs and Reserves shall be computed without duplication, and
without duplication of amounts included in the Project Overhead/Advances or
Original Indebtedness and Preferred Equity.

The calculation of the Total Consideration pursuant to the above formula shall
be performed by, or under the direction of, Richard Gilchrist, who is an officer
of the Company and the Operating Partnership. NOTWITHSTANDING ANYTHING TO THE
CONTRARY IN THIS CONTRIBUTION AGREEMENT, INCLUDING SECTION 7.1 HEREOF, THE
CONTRIBUTOR AGREES THAT, SO LONG AS CONTRIBUTOR RECEIVES THE MINIMUM
CONSIDERATION, THE CALCULATION OF TOTAL CONSIDERATION SHALL BE FINAL AND BINDING
UPON HIM, AND THAT HE SHALL HAVE NO RIGHT TO DISPUTE ANY ASPECT OF THE
CALCULATION WHATSOEVER. CONTRIBUTOR HEREBY IRREVOCABLY WAIVES ANY AND ALL CLAIMS
RELATING TO THE CALCULATION OF THE TOTAL CONSIDERATION.

The Contributor shall be provided with a good faith estimated calculation of
Pre-Public Offering Indebtedness and Preferred Equity, Project
Overhead/Advances, Development Term Loan Reimbursement Amount, and Transaction
Costs and Reserves at least one week prior to the anticipated pricing of the
Public Offering.

                                 OF CONTRIBUTOR

        Except as set forth in the disclosure schedule delivered to the
Operating Partnership on the date hereof specifically noting any exception to
the representations and warranties of Contributor and the particular
representation or warranty of Contributor to which any such exception applies,
Contributor represents and warrants to the Operating Partnership as set forth
below in this Article 2, which representations and warranties are true and
correct as of the date hereof and will be true and correct as of the date of
Closing. Notwithstanding any other provision of the Agreement or this Exhibit D,
Contributor makes representations, warranties and indemnities only with respect
to the interests in each of the Partnerships to be transferred by Contributor
identified on Exhibit A to the Agreement.

        2.1 Organization; Authority. Contributor (A) if a natural person, has
the legal capacity to enter the Agreement, each agreement contemplated thereby
and to carry out the transactions contemplated thereby; if not a natural person,
is duly formed, validly existing and in good standing (to the extent applicable)
under the laws of the jurisdiction of its formation, and (B) has all requisite
power and authority to enter the Agreement, each agreement contemplated thereby
and to carry out the transactions contemplated thereby, and own, lease or
operate its property and to carry on its business as presently conducted and, to
the extent required under



                               Exhibit D, Page 2

<PAGE>

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.

        2.2 Due Authorization. This Agreement and each agreement, document and
instrument executed and delivered by or on behalf of Contributor pursuant to
this Agreement constitutes, or when executed and delivered will constitute, the
legal, valid and binding obligation of Contributor, each enforceable against
Contributor in accordance with its terms, as such enforceability may be limited
by bankruptcy or the application of equitable principles.

        2.3 Consents and Approvals. Except as shall have been satisfied prior to
the Closing Date and in any case as set forth on the disclosure schedule, no
consent, waiver, approval or authorization of any spouse, third party or
governmental authority or agency is required to be obtained by Contributor in
connection with the execution, delivery and performance of the Agreement and the
transactions contemplated thereby between the parties to this Agreement.

        2.4 Ownership of the Partnership Interests. Contributor is the sole
owner of its Partnership Interests beneficially and of record free and clear of
any Liens of any nature and has full power and authority to convey the
Partnership Interests free and clear of any Liens, and, upon delivery of
consideration for such Partnership Interests as herein provided, the Operating
Partnership will acquire good and valid title thereto, free and clear of any
Liens except Liens created in favor of the Operating Partnership by the
transactions contemplated in the Agreement or Liens created by the Executive
Equity Agreements in favor of Robert F. Maguire III or any entity owned or
controlled by Robert F. Maguire III. Contributor's spouse has consented to the
sale of the Partnership Interest as herein provided for the consideration
recited herein and, after the Closing, Contributor and Contributor's spouse will
have no right or interest in the Partnership Interests or the Properties. Except
for purchase rights in favor of Robert F. Maguire or any entity owned or
controlled by Robert F. Maguire III as provided in the Executive Equity
Agreements, there are no rights, subscriptions, warrants, options, conversion
rights, preemptive rights, agreements, instruments or understandings of any kind
outstanding (i) relating to the Partnership Interests or (ii) to purchase,
transfer or to otherwise acquire, or to in any way encumber, any of the
interests which comprise the Partnership Interests or any securities or
obligations of any kind convertible into any of the interests which comprise the
Partnership Interests or other equity interests or profit participation of any
kind in any of the Partnerships. Contributor will not consent to join in or in
any way effect the transfer of any Property Interest or Partnership Interest
prior to the Closing. Except as set forth in the disclosure schedule and other
than with respect to any rights or interests which are the subject of the RFM
Option Agreement, Contributor has no equity interest, either direct or indirect,
in the Properties, except for the Partnership Interests which are the subject of
the Agreement, and no rights or interests in any assets owned, in whole or part,
directly or indirectly by Robert F. Maguire III, including without limitation,
any Projects.

        2.5 No Violation. None of the execution, delivery or performance of the
Agreement, any agreement contemplated thereby between the parties to this
Agreement and the transactions contemplated thereby between the parties to this
Agreement 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, acceleration, cancellation or
other right adverse to the Operating Partnership of (A) the organizational
documents,



                               Exhibit D, Page 3

<PAGE>

including the charters and bylaws, if any, of Contributor, (B) any agreement,
document or instrument to which Contributor is a party or by which Contributor
or its Partnership Interests are bound or (C) any term or provision of any
judgment, order, writ, injunction, or decree, or require any approval, consent
or waiver of, or make any filing with, any person or governmental or regulatory
authority or foreign, federal, state, local or other law binding on Contributor
(or its assets or properties) or, to Contributor's Knowledge, the Partnership
(or its assets or properties), which has or may be reasonably expected to have
an adverse effect on Contributor, the Partnership or any of their respect assets
or properties, or (ii) result in the creation of any Lien upon any of the
Partnership Interests.

        2.6 Non-Foreign Status. Contributor is a United States person (as
defined in Section 7701(a)(30) of the Code), and is, therefore, not subject to
the provisions of the Code relating to the withholding of sales proceeds to
foreign persons, and is not subject to any state withholding requirements.
Contributor will provide affidavits to this effect as provided for in Section
2.3(f) of the Agreement.

        2.7 Withholding. Contributor shall execute at Closing such certificates
or affidavits reasonably necessary to document the inapplicability of any
federal or state withholding provisions, including without limitation those
referred to in Section 2.6 above. If Contributor fails to provide such
certificates or affidavits, the Operating Partnership's sole remedy will be to
withhold a portion of any payments otherwise to be made to Contributor as
required by the Code or applicable state law.

        2.8 Investment Purposes. Contributor acknowledges his, her or its
understanding that the offering and issuance of the Partnership Units to be
acquired pursuant to the Agreement are intended to be exempt from registration
under the Securities Act of 1933, as amended and the rules and regulations in
effect thereunder (the "Act") and that the Operating Partnership's reliance on
such exemptions is predicated in part on the accuracy and completeness of the
representations and warranties of the Contributor contained herein. In
furtherance thereof, Contributor represents and warrants to the Company as
follows:

               2.8.1 Investment. Contributor is acquiring the Partnership Units
solely for his, her or its own account for the purpose of investment and not as
a nominee or agent for any other person and not with a view to, or for offer or
sale in connection with, any distribution of any thereof. Contributor agrees and
acknowledges that he, she or it will not, directly or indirectly, offer,
transfer, sell, assign, pledge, hypothecate or otherwise dispose of
(hereinafter, "Transfer") any of the Partnership Units unless (i) the Transfer
is pursuant to an effective registration statement under the Act and
qualification or other compliance under applicable blue sky or state securities
laws, or (ii) counsel for Contributor (which counsel shall be reasonably
acceptable to the Operating Partnership) shall have furnished the Operating
Partnership with an opinion, reasonably satisfactory in form and substance to
the Operating Partnership, to the effect that no such registration is required
because of the availability of an exemption from registration under the Act and
qualification or other compliance under applicable blue sky or state securities
laws. The term "Transfer" shall not include any redemption of the Partnership
Units or exchange of the Partnership Units for REIT Shares pursuant to Section
8.6 of the OP Agreement. Notwithstanding the foregoing, no Transfer shall be
made unless it is permitted under the OP Agreement.



                               Exhibit D, Page 4

<PAGE>

               2.8.2 Knowledge. Contributor is knowledgeable, sophisticated and
experienced in business and financial matters; Contributor has previously
invested in securities similar to the Partnership Units and fully understands
the limitations on transfer imposed by the Federal securities laws and as
described in the Agreement. Contributor is able to bear the economic risk of
holding the Partnership Units for an indefinite period and is able to afford the
complete loss of his, her or its investment in the Partnership Units;
Contributor has received and reviewed all information and documents about or
pertaining to the Company, the Operating Partnership, the business and prospects
of the Company and the Operating Partnership and the issuance of the Partnership
Units as Contributor deems necessary or desirable, has had cash flow and
operations data for the Properties made available by the Operating Partnership
upon request and has been given the opportunity to obtain any additional
information or documents and to ask questions and receive answers about such
information and documents, the Company, the Operating Partnership, the
Properties, the business and prospects of the Company and the Operating
Partnership and the Partnership Units which Contributor deems necessary or
desirable to evaluate the merits and risks related to his, her or its investment
in the Partnership Units and to conduct its own independent valuation of the
Properties; and Contributor understands and has taken cognizance of all risk
factors related to the purchase of the Partnership Units. Contributor is a
sophisticated real estate investor. Contributor is relying upon its own
independent analysis and assessment (including with respect to taxes), and the
advice of Contributor's advisors (including tax advisors), and not upon that of
the Operating Partnership or any of the Operating Partnership's affiliates, for
purposes of evaluating, entering into, and consummating the transactions
contemplated by the Agreement.

               2.8.3 Holding Period. Contributor acknowledges that he, she or it
has been advised that (i) the Partnership Units and the common stock of the
Company (the "Common Stock") into which the Partnership Units may be exchanged
in certain circumstances must be held indefinitely, and Contributor must
continue to bear the economic risk of the investment in the Partnership Units
(and any Common Stock that might be exchanged therefor), unless they are
subsequently registered under the Act or an exemption from such registration is
available (it being understood that the Operating Partnership has no intention
of so registering the Partnership Units), (ii) a restrictive legend in the form
hereafter set forth shall be placed on the certificates representing the
Partnership Units (and any Common Stock that might be exchanged therefor), and
(iii) a notation shall be made in the appropriate records of the Operating
Partnership (and the Company) indicating that the Partnership Units (and any
Common Stock that might be exchanged therefor) are subject to restrictions on
transfer.

               2.8.4 Accredited Investor. Contributor is an "accredited
investor" (as such term is defined in Rule 501 (a) of Regulation D under the
Act). Contributor has previously provided the Operating Partnership with a duly
executed Accredited Investor Questionnaire. No event or circumstance has
occurred since delivery of such Questionnaire to make the statements contained
therein false or misleading.

               2.8.5 Legending. Each certificate representing the Partnership
Units (and any Common Stock that might be exchanged therefor) shall bear the
following legend:

        THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR THE



                                Exhibit D, Page 5

<PAGE>

        SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, TRANSFERRED OR
        OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION, UNLESS THE
        TRANSFEROR DELIVERS TO THE COMPANY AN OPINION OF COUNSEL SATISFACTORY TO
        THE COMPANY, TO THE EFFECT THAT THE PROPOSED SALE, TRANSFER OR OTHER
        DISPOSITION MAY BE EFFECTED WITHOUT REGISTRATION UNDER THE ACT AND UNDER
        APPLICABLE STATE SECURITIES OR "BLUE SKY" LAWS;

               In addition, the Common Stock for which the Partnership Units
might be exchanged shall also bear a legend which generally provides the
following:

        THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
        TO RESTRICTIONS ON BENEFICIAL AND CONSTRUCTIVE OWNERSHIP AND TRANSFER
        FOR THE PURPOSE OF THE CORPORATION'S MAINTENANCE OF ITS STATUS AS A REAL
        ESTATE INVESTMENT TRUST UNDER THE INTERNAL REVENUE CODE OF 1986, AS
        AMENDED (THE "CODE"). SUBJECT TO CERTAIN FURTHER RESTRICTIONS AND EXCEPT
        AS EXPRESSLY PROVIDED IN THE CORPORATION'S ARTICLES OF RESTATEMENT, (i)
        NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF THE
        CORPORATION'S COMMON STOCK IN EXCESS OF 9.8% (BY VALUE OR BY NUMBER OF
        SHARES, WHICHEVER IS MORE RESTRICTIVE) OF THE OUTSTANDING COMMON STOCK
        OF THE CORPORATION; (ii) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY
        OWN SHARES OF COMMON STOCK THAT WOULD RESULT IN THE CORPORATION BEING
        "CLOSELY HELD" UNDER SECTION 856(h) OF THE CODE OR OTHERWISE CAUSE THE
        CORPORATION TO FAIL TO QUALIFY AS A REIT; AND (iii) NO PERSON MAY
        TRANSFER SHARES OF COMMON STOCK IF SUCH TRANSFER WOULD RESULT IN THE
        CAPITAL STOCK OF THE CORPORATION BEING OWNED BY FEWER THAN 100 PERSONS.
        ANY PERSON WHO BENEFICIALLY OR CONSTRUCTIVELY OWNS OR ATTEMPTS TO
        BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF COMMON STOCK IN VIOLATION
        OF THE ABOVE LIMITATIONS MUST IMMEDIATELY NOTIFY THE CORPORATION. IF ANY
        OF THE RESTRICTIONS ON TRANSFER OR OWNERSHIP ARE VIOLATED, THE SHARES OF
        COMMON STOCK REPRESENTED HEREBY WILL BE AUTOMATICALLY TRANSFERRED TO THE
        TRUSTEE OF A TRUST FOR THE BENEFIT OF ONE OR MORE CHARITABLE
        BENEFICIARIES. IN ADDITION, THE CORPORATION MAY REDEEM SHARES UPON THE
        TERMS AND CONDITIONS SPECIFIED BY THE BOARD OF DIRECTORS IN ITS SOLE
        DISCRETION IF THE BOARD OF DIRECTORS DETERMINES THAT OWNERSHIP OR A
        TRANSFER OR OTHER EVENT MAY VIOLATE THE RESTRICTIONS DESCRIBED ABOVE.
        FURTHERMORE, UPON THE OCCURRENCE OF CERTAIN EVENTS, ATTEMPTED TRANSFERS
        IN VIOLATION OF THE RESTRICTIONS DESCRIBED ABOVE MAY BE VOID AB INITIO.
        ALL TERMS IN THIS LEGEND THAT ARE DEFINED IN THE ARTICLES OF RESTATEMENT
        OF THE CORPORATION SHALL HAVE THE MEANINGS ASCRIBED TO THEM IN THE
        ARTICLES OF RESTATEMENT OF THE CORPORATION, AS THE SAME MAY BE AMENDED
        FROM TIME TO TIME, A COPY OF WHICH, INCLUDING THE RESTRICTIONS ON
        TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO EACH HOLDER OF SHARES OF
        COMMON STOCK ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY
        BE DIRECTED TO THE SECRETARY OF THE CORPORATION AT ITS PRINCIPAL OFFICE.



                                Exhibit D, Page 6

<PAGE>

               2.9 No Brokers. Contributor has not 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 the Agreement and
Contributor shall indemnify and hold harmless the Operating Partnership for all
costs and expenses incurred by the Operating Partnership as a result of a breach
of this representation. The provisions of this Section 2.9 shall survive the
Closing or termination of this Agreement.

               2.10 Solvency. Contributor has been and will be solvent at all
times prior to and for the ninety day period immediately following the transfer
of its Partnership Interests to the Operating Partnership.

               2.11 Taxes. To the Contributor's Knowledge, no tax lien or other
charge exists or will exist upon consummation of the transactions contemplated
hereby with respect to any Property, except such tax liens for which the tax is
not due and has been reserved for payment by the Partnership or tax liens or
other charges which individually or in the aggregate would not have a material
adverse effect on the Operating Partnership.

               2.12 Litigation. To the Contributor's Knowledge, there is no
litigation or proceeding, either judicial or administrative, pending or overtly
threatened, affecting all or any portion of Contributor's Partnership Interests
or Contributor's ability to consummate the transactions contemplated hereby.
Contributor knows of no outstanding order, writ, injunction or decree of any
court, government, governmental entity or authority or arbitration against or
affecting all or any portion of its Partnership Interests, which in any such
case would impair Contributor's ability to enter into and perform all of its
obligations under the Agreement.

               2.13 NASD Affiliation. Contributor represents severally that
neither it nor any affiliate of Contributor is a member, affiliate of a member
or person associated with a member of the National Association of Securities
Dealers, Inc. ("NASD"). Contributor further represents severally that neither it
nor any of its affiliates owns any stock or other securities of any NASD member
not purchased in the open market, or has made any outstanding subordinated loans
to a NASD member. (A company or natural person is presumed to control a member
of the NASD and is therefore presumed to constitute an affiliate of such member
if the Company or person is the beneficial owner of 10% or more of the
outstanding securities of a member which is a corporation. Additionally, a
natural person is presumed to control a member of the NASD and is therefore
presumed to constitute an affiliate of such a member if such person has the
power to direct or cause the direction of the management or policies of such
member.)

               2.14 Covenant to Remedy Breaches. Contributor covenants to use
all reasonable efforts within its control (a) to prevent the breach of any
representation or warranty of Contributor hereunder, (b) to satisfy all
covenants of Contributor hereunder and (c) to promptly cure any breach of a
representation, warranty or covenant of Contributor hereunder upon its learning
of same.

<PAGE>

                          ARTICLE 3 -- INDEMNIFICATION

        3.1 Survival Of Representations And Warranties; Remedy For Breach.

        (a) Subject to Section 3.6, all representations and warranties contained
in this Exhibit D or in any Schedule or certificate delivered pursuant hereto
shall survive the Closing.

        (b) Notwithstanding anything to the contrary in the Agreement or this
Exhibit D, no party hereto shall be liable under this Exhibit D or the Agreement
for monetary damages (or otherwise) for breach of any of its representations and
warranties contained in this Exhibit D or the Agreement, or in any Schedule,
certificate or affidavit delivered by it pursuant thereto, other than pursuant
to the succeeding provisions of this Section 3.

        3.2 General Indemnification.

        (a) Contributor shall indemnify and hold harmless the Operating
Partnership, the Company, and their affiliates and each of their respective
directors, officers, employees, agents, representatives and affiliates (each of
which is an "Indemnified Party") from and against any and all Claims, losses,
damages, liabilities and expenses, including, without limitation, amounts paid
in settlement, reasonable attorneys' fees, costs of investigation, costs of
investigative, judicial or administrative proceedings or appeals therefrom, and
costs of attachment or similar bonds (collectively, "Losses"), asserted against,
imposed upon or incurred by the Indemnified Party in connection with or as a
result of any breach of a representation, warranty or covenant of Contributor
contained in the Agreement or in any Schedule, Exhibit, certificate or affidavit
or in any other document delivered by Contributor pursuant to the Agreement.

        (b) Contributor shall indemnify and hold harmless the Indemnified
Parties from and against any and all Losses asserted against, imposed upon or
incurred by the Indemnified Parties in connection with or as a result of:

        (i) all fees and expenses of Contributor in connection with the
transactions contemplated by the Agreement; and

        (ii) any liabilities or obligations incurred, arising from or out of, in
connection with or as a result of the failure of Contributor to obtain all
consents required to consummate the transactions contemplated by the Agreement.

        3.3 Payment of Indemnification. Contributor shall (as provided in
Section 3.5(b)) satisfy its obligations hereunder by the prompt delivery (paid
promptly as and when expenses are incurred) to an Indemnified Party of its
Partnership Units (if any). Any Partnership Units delivered to an Indemnified
Party hereunder shall be valued based upon the initial public offering price of
the Company's Common Stock.

        3.4 Notice and Defense of Claims. As soon as reasonably practicable
after receipt by the Indemnified Party of notice of any liability or claim
incurred by or asserted against the Indemnified Party that is subject to
indemnification under this Article 3, the Indemnified Party shall give notice
thereof to Contributor, including liabilities or claims to be applied against



                               Exhibit D, Page 8

<PAGE>

the indemnification baskets established pursuant to Section 3.5 hereof. The
Indemnified Party may at its option demand indemnity under this Article 3 as
soon as a claim has been threatened by a third party, regardless of whether an
actual Loss has 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, a Loss as a result thereof and shall give
notice of such determination to Contributor. The Indemnified Party shall assume
the defense of any such claim by counsel selected by Indemnified Party and
reasonably satisfactory to Contributor, and may settle or otherwise dispose of
the same; PROVIDED, HOWEVER, that the Contributor may at all times participate
in such defense at its own expense, which shall not be reimbursed by Indemnified
Party.

        3.5 Limitations on and Threshold for Indemnification Under Section 3.2.

        (a) Contributor shall not be liable under Section 3.2 hereof unless and
until the total amount recoverable by the Indemnified Parties under Section 3.2
exceeds $100,000; PROVIDED, HOWEVER, that claims for Losses arising out of a
breach of representation or warranty contained in sections 2.1, 2.2, 2.4, 2.6,
2.7, and 2.9 hereof shall not be subject to such threshold amount but shall be
recoverable from the first dollar of Losses; and PROVIDED FURTHER, that once the
total amount recoverable by the Indemnified Parties under Section 3.2 hereof
exceeds $100,000 in the aggregate, Contributor's obligation under Section 3.2
hereof shall be for the full amount of such obligation.

        (b) Notwithstanding anything contained herein to the contrary,
Contributor shall not be liable or obligated to make payments under this Article
3 with respect to any Partnership Interest to the extent such payments in the
aggregate would exceed (i) if the Cash-Out Option is not exercised, the value of
the Partnership Units (based upon the initial public offering price of the
Common Stock) received by Contributor at the Closing or (ii) if the Cash-Out
Option is exercised, the amount of cash consideration received by the
Contributor pursuant to the Agreement at the Closing. Notwithstanding anything
contained herein to the contrary, the Indemnified Parties shall look first to
Contributor's Partnership Units (if any) for indemnification under this Article
3 (and agree to treat any return of Partnership Units as an adjustment to the
consideration delivered to Contributor pursuant to the Formation Transactions),
then to any distributions received by Contributor in connection with
Contributor's Partnership Units and then to any cash consideration paid to
Contributor pursuant to this Agreement.

        3.6 Limitation Period.

        (a) Notwithstanding the foregoing, any claim for indemnification under
Section 3.2 hereof must be asserted in writing by the Indemnified Party, stating
the nature of the Losses and the basis for indemnification therefor:

               (i) within one year after the Closing in the case of a claim
under Section 3.2 hereof (other than a claim under Section 3.2 (a) based upon a
breach of the representations, and warranties of Contributor set forth in
Sections 2.1, 2.2, 2.4, 2.6, 2.7 and 2.9 hereof); and

               (ii) prior to the expiration of the applicable statutes of
limitations in the case of a claim under Section 3.2 (a) based upon a breach of
the representations and warranties of Contributor set forth in Sections 2.1,
2.2, 2.4, 2.6, 2.7 and 2.9 hereof.

        (b) If so asserted in writing within one year after the Closing or prior
to the expiration of the applicable statute of limitation, as applicable, such
claims for indemnification shall survive until resolved by mutual agreement
between Contributor and the Indemnified Party or by judicial determination. Any
claim for indemnification not so asserted in writing within one year after the
Closing or prior to the expiration of the applicable statute of limitation, as
applicable, shall not thereafter be asserted and shall forever be waived.

                             CONTRIBUTION AGREEMENT

                     CERTIFICATION OF NON-FOREIGN STATUS(1)

         Section 1445 of the Internal Revenue Code of 1986, as amended provides
that a transferee of a United States real property interest must withhold tax if
the transferor is a foreign person. To inform the Operating Partnership that the
withholding of tax is not required upon the distribution of Units or payment of
cash to me following the contribution or sale, as applicable, of the Partnership
Interests to the Operating Partnership, I, William Thomas Allen, hereby certify
the following:

         1.  I am not a nonresident alien for purposes of U.S. income taxation;

         2.  My taxpayer identifying number (Social Security number) is
             ###-##-####; and

         3.  My home address is:

                  9221 Canter
                  Dallas, Texas 75231

         I understand that this certification may be disclosed to the Internal
Revenue Service by the Operating Partnership and that any false statement I have
made here could be punishable by fine, imprisonment or both.

         Under penalties of perjury, I declare that I have examined this
certification and, to the best of my knowledge and belief, it is true, correct
and complete.

agree to be bound by the provisions of said Agreement to the extent of any
community property interest that I may have that may be affected thereby.
