                             CONTRIBUTION AGREEMENT

            THIS CONTRIBUTION AGREEMENT (including all exhibits, hereinafter
referred to as this "Agreement") is made and entered into as of November 5, 2002
by and between Maguire Properties, L.P., a Maryland limited partnership (the
"Operating Partnership"), and Maguire Partners -- Master Investments, LLC, a
California limited liability company (the "Contributor"), and for purposes of
Articles IV, V and VI only, Robert F. Maguire III, an individual, Nelson C.
Rising, an individual ("Rising"), Richard I. Gilchrist, an individual
("Gilchrist") and Edward D. Fox, Jr. an individual ("Fox") (each, also a
"Contributor" as the context requires for purposes of Articles IV, V and VI and
collectively, the "Contributors").

                                    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 and certain limited liability companies (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. 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 also set forth on Exhibit A (each, a
"Property" and together the "Properties"). As used herein, "Partnership
Agreement" means the respective partnership agreement or limited liability
company agreement, as applicable, under which each Partnership was formed
(including all amendments or restatements).

            E. 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,

                                       1
<PAGE>

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 Partnership Units, on the terms
and subject to the conditions set forth herein.

            F. Each 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
a another Person or a Partnership with and into the Company, the Operating
Partnership or an Affiliate (as defined in Exhibit D) of either of them (a
"Merger"), or to divide a Partnership into more than one partnership to
facilitate the Formation Transactions (a "Division"); and, so long as the
Operating Partnership agrees to hold each Contributor harmless for any
additional adverse tax consequences to such Contributor or additional costs or
liabilities incurred by such Contributor as a result of any restructuring
pursuant to this Recital F as provided in Section 5.4 hereof, each 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 any 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.

            G. The parties acknowledge that the Operating Partnership's
acquisition of the Partnership Interests and the Contributor's contribution of
its Partnership Interests is in connection with and 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:

                               TERMS OF AGREEMENT

                                   ARTICLE I.
                      CONTRIBUTION OF PARTNERSHIP INTERESTS
                       AND EXCHANGE FOR PARTNERSHIP UNITS

      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, but without recourse,
representation or warranty except as expressly set forth herein (including
Exhibit D hereto), all of its Partnership Interests, including all of
Contributor's rights

                                       2
<PAGE>

and interests to the Partnerships and all rights to indemnification in favor of
Contributor under the agreements pursuant to which Contributor or its Affiliates
acquired the Partnership Interests transferred pursuant to this Agreement. The
contribution of the Partnership Interests shall be evidenced by a Contribution
and Assumption Agreement in substantially the form of Exhibit B attached hereto.
Furthermore, Contributor shall execute and upon the Operating Partnership's
request shall cause each of its individual constituent partners, members and/or
beneficiaries (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
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 (without, however, the expenditure
of any additional money or the incurring of any additional liability by
Contributor not contemplated herein (including Exhibit D hereto) unless advanced
such money or held harmless from such additional liability by the Operating
Partnership by agreement in form and substance reasonably acceptable to
Contributor).

      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 the Contributor the aggregate 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 the 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 the
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.

      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 it would be inappropriate
for the Operating Partnership to own the underlying Property.

            The risk of loss relating to the Partnership Interests and the
underlying Properties prior to Closing shall be borne by Contributor. If, prior
to the Closing, any Property is materially destroyed or damaged by fire or other
casualty, then the Operating Partnership may, at its option, determine not to
acquire a particular Property, including Contributor's interest in the
Partnership that directly or indirectly owns such Property, that has been
destroyed or damaged. Under such circumstances, Contributor acknowledges that
the Total Consideration will likely be correspondingly reduced. After the
occurrence of any such casualty affecting a Property, the Operating Partnership
may also, at its option, elect to (a) acquire Contributor's interest in any

                                       3
<PAGE>

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.

      Section 1.4 Tax Treatment of Transaction.

            The transfer, assignment and exchange effectuated pursuant to this
Agreement 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 and each Contributor (or such other transferor)
hereby consents to such treatment.

      Section 1.5 Allocation of Total Consideration.

            The Total Consideration shall be allocated among the Partnership
Interests in a manner reasonably determined by the Operating Partnership. The
Operating Partnership and Contributor agrees 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.

      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 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.

      Section 1.8 Sale Limitations and Debt Guarantees.

            In connection with the Formation Transactions, the Operating
Partnership has agreed to certain limitations on its ability to sell its direct
or indirect interests in the Participating Properties and to use commercially
reasonable efforts to make certain debt available to be guaranteed by
Contributor, as set forth on Exhibit G.

                                   ARTICLE II.

                 REPRESENTATIONS AND WARRANTIES AND INDEMNITIES

      Section 3.1 Representations and Warranties of the Operating Partnership.

            The Operating Partnership hereby represents and warrants to and
covenants with Contributor that as of the date hereof and as of the Closing
Date:

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

                                       7
<PAGE>

power and authority to enter this Agreement, each agreement contemplated hereby
and to carry out the transactions contemplated hereby and thereby, and own,
lease or operate its property and to carry on its business as presently
conducted and, to the extent required under applicable law, is qualified to do
business and is in good standing in each jurisdiction in which the nature of its
business or the character of its property make such qualification necessary.

            (b) Due Authorization. The execution, delivery and performance of
this Agreement by the Operating Partnership has been duly and validly authorized
by all necessary action of the Operating Partnership. This Agreement and each
agreement, document and instrument executed and delivered by or on behalf of the
Operating Partnership pursuant to this Agreement constitutes, or when executed
and delivered will constitute, the legal, valid and binding obligation of the
Operating Partnership, each enforceable against the Operating Partnership in
accordance with its terms, as such enforceability may be limited by bankruptcy
or the application of equitable principles.

            (c) Consents and Approvals. Except in connection with the Public
Offering and the consummation of the Formation Transactions, no consent, waiver,
approval or authorization of any third party or governmental authority or agency
is required to be obtained by the Operating Partnership in connection with the
execution, delivery and performance of this Agreement and the transactions
contemplated hereby, except any of the foregoing that shall have been satisfied
prior to the Closing Date.

            (d) Brokers. The Operating Partnership has not employed or made any
agreement with any broker, finder or similar agent or firm which will result in
the obligation of the Contributor to pay any finder's fees, brokerage fees or
commissions or similar payments in connection with the transactions contemplated
by this Agreement.

            (e) Knowledge of Properties. The Operating Partnership is a
sophisticated real estate investor. The Operating Partnership is relying upon
its own independent analysis and assessment, and the advice of such the
Operating Partnership's advisors, and not upon that of Contributor or any of
Contributor's Affiliates, for purposes of evaluating, entering into, and
consummating the transactions contemplated by this Agreement.

            (f) No Violation. None of the execution, delivery or performance of
this Agreement, any agreement contemplated hereby between the parties to this
Agreement and the transactions contemplated hereby 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 Contributor of (A) the organizational documents of
the Operating Partnership, or (B) any term or provision of any judgment, order,
writ, injunction, or decree binding on the Operating Partnership, or, other than
in connection with the Offering and the Formation Transactions, require any
approval, consent or waiver of, or make any filing with, any person or
governmental or regulatory authority or under any foreign, federal, state, local
or other law binding on the Operating Partnership (or its assets or properties).

            (g) Partnership Units. The Partnership Units to be issued to the
Contributor pursuant to this Agreement will have been duly authorized and, when
issued against the

                                       8
<PAGE>

consideration therefor, will, subject to the terms of the OP Agreement, be
validly issued to the Contributor by the Operating Partnership free and clear of
all Liens created by the Operating Partnership.

            (h) OP Agreement. As of the date hereof, the Operating Partnership
has delivered to counsel for Contributor the Partnership Agreement of the
Operating Partnership as well as a current draft of the proposed amended and
restated OP Agreement, which is in substantially the form in which it will be
executed by the parties at the Closing, other than for such changes that may be
made after the date hereof that are not disproportionately adverse to
Contributor as opposed to other limited partners (including Robert F. Maguire
III).

            (i) Material Agreements. None of the execution, delivery or
performance of this Agreement, any agreement contemplated hereby between the
parties to this Agreement and the transactions contemplated hereby between the
parties to this Agreement does or will, with or without the giving of notice,
lapse of time, or both 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 Contributor of any
material agreement, document or instrument to which the Operating Partnership is
a party or by which its property or interests are bound.

      Section 3.2 Representations and Warranties of Contributor.

            Contributor represents and warrants to and covenants with the
Operating Partnership as provided in Exhibit D attached hereto, and acknowledges
and agrees to be bound by the indemnification provisions contained therein.
Contributor hereby agrees promptly to give the Operating Partnership written
notice upon obtaining actual knowledge of any information which makes any
representation or warranty made by Contributor hereunder untrue, and in any
event to give written notice within five (5) business days of obtaining actual
knowledge of such information.

      Section 3.3 Indemnification.

            The Operating Partnership shall indemnify and hold harmless each
Contributor and its directors, beneficiaries, officers, employees, agents,
representatives and Affiliates (each of which is an "Indemnified Contributor
Party") from and against any and all charges, complaints, claims, actions,
causes of action, losses, damages, liabilities and expenses of any nature
whatsoever, 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") arising out of or relating to, asserted
against, imposed upon or incurred by the Indemnified Contributor Party in
connection with: (i) any breach of a representation, warranty or covenant of the
Operating Partnership contained in this Agreement (including, without
limitation, any breach of the Power of Attorney as set forth in Article VI
below), (ii) all fees, costs and expenses of the Operating Partnership in
connection with the transactions contemplated by this Agreement, including
without limitation any and all costs associated with the transfers contemplated
herein, and (iii) the Partnerships, except in each case for matters arising from
the breach by Contributor of any representation, warranty, covenant or
obligation under this Agreement, any Partnership Agreement, or any agreement
contemplated by this Agreement or

                                       9
<PAGE>

from Contributor's gross negligence or willful misconduct. The notice and
defense requirements set forth in Section 3.4 of Exhibit D attached hereto shall
apply mutatis mutandis to this Section 3.3; provided, however, that if the
Operating Partnership is required to retain counsel, any such counsel shall be
selected by the Operating Partnership. Notwithstanding anything to the contrary
in this Agreement, this Section 3.3 shall be the sole and exclusive remedy of
each Contributor for breach by the Operating Partnership of any of its
representations, warranties and covenants contained in this Agreement, or in any
Schedule, certificate or affidavit delivered by it pursuant hereto.
Notwithstanding anything contained herein to the contrary, no Indemnified
Contributor Party shall have the right to receive or recover punitive damages
against the Operating Partnership by reason of any breach under or in connection
with this Agreement or any schedule, exhibit, certificate or affidavit or any
other document delivered by the Operating Partnership pursuant to this
Agreement, and each Indemnified Contributor Party hereby waives any and all
right to receive such punitive damages.

                                   ARTICLE IV.

Partnership and not otherwise in the Operating Partnership's possession or
control and to cooperate with the Operating Partnership with respect to its
filing of tax returns.

      Section 4.2 Consents.

            Each Contributor shall use its good faith diligent efforts to obtain
any approvals, waivers or other consents of third parties, governmental
authorities and agencies required to effect the transactions contemplated by

<PAGE>

      Section 4.3 Representations/Covenants of Gilchrist, Rising and Fox.

            Each of Gilchrist, Rising and Fox represent and warrant that upon
the consummation of the transactions contemplated by this Agreement such person
will not have any further rights, interests, or claims, of any kind, directly or
indirectly, in or to any of the Properties or any other properties or assets
owned and controlled by Robert F. Maguire III. To the extent that any of
Gilchrist, Rising and Fox may hold any such interests, rights or claims, each of
Gilchrist, Rising and Fox covenant to take all necessary actions to contribute
such interests, rights or claims in any Properties to the Operating Partnership
and any such interests, rights or claims in any other properties or assets owned
and controlled by Robert F. Maguire III to Mr. Maguire or his designee.

                                   ARTICLE V.
                              RELEASES AND WAIVERS

            Each of the releases and waivers enumerated in this Article 5 shall
become effective only upon the Closing of the contribution of the Partnership
Interests pursuant to Articles 1 and 2 herein and the Contributor's receipt of
the Total Consideration.

      Section 5.1 General Release of Operating Partnership.

            As of the Closing, each Contributor irrevocably waives, releases and
forever discharges the Company, the Operating Partnership and each of the
Operating Partnership's direct or indirect subsidiaries, directly or indirectly

Partnership), agents, attorneys, successors and assigns of and from, any and all
obligations, charges, complaints, claims, liabilities, damages, actions, causes
of action, losses and costs of any nature whatsoever existing as of the Closing

unsuspected, arising out of or relating to any Partnership Agreement, the
Partnerships, the Properties or any other matter which exists at the Closing,
except for Contributor Claims arising from the breach of any representation,
warranty, covenant or obligation by the Operating Partnership under this
Agreement, any agreement contemplated hereby or entered into in connection

      Section 5.2 General Release of Contributors.

            As of the Closing, the Operating Partnership (on behalf of itself
and the Company) irrevocably waives, releases and forever discharges each

and from, any and all obligations, charges, complaints, claims, liabilities,
damages, actions, causes of action, losses and costs of any nature whatsoever
existing as of the Closing (collectively, "Operating Partnership Claims"), known
or unknown, suspected or unsuspected, arising out of or relating to any
Partnership Agreement, the Partnerships, the Properties or any other matter
which exists at the Closing, except for Operating Partnership Claims arising
from the breach of any representation, warranty, covenant or obligation by such

      Section 5.3 Waiver of Section 1542 Protections.

            As of the Closing, each Contributor and the Operating Partnership
(on behalf of itself and the Company) expressly acknowledges that it has had, or
has had and waived, the opportunity to be advised by independent legal counsel
and hereby waives and relinquishes all rights and benefits afforded by Section
1542 of the California Civil Code and does so understanding and acknowledging
the significance and consequence of such specific waiver of Section 1542 which
provides:

            A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
            NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING
            THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED THE
            SETTLEMENT WITH THE DEBTOR.

      Section 5.4 Waiver of Rights Under Partnership Agreements; Consents With
Respect to Partnership Interests.

            (a) As of the Closing, each Contributor waives and relinquishes all
rights and benefits otherwise afforded to such Contributor under any Partnership
Agreement 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). Each
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 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 such Contributor represents a direct or indirect
interest, each 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, (ii) cause the Partnership to have authority to
transfer the Partnership Interests or Properties to the Operating Partnership,
and (iii) allow Contributors to receive Partnership Units 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 Contributors contributing their 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 Contributors receiving any amount hereunder from such
Partnership or its subsidiaries making such direct transfer; provided that the
Operating Partnership shall hold each Contributor harmless (by an agreement in
form and substance reasonably acceptable to Contributor and consistent with the
terms of this Section 5.4) for any additional adverse tax consequences to such
Contributor or additional costs or liabilities incurred by such Contributor, in
each case solely as a result of any Conveyance Action and in excess of those
contemplated herein (including Exhibit D) that would have resulted were the
transactions consummated pursuant to the contributions contemplated by
Section 1.1. In

                                       12
<PAGE>
addition, if the Closing occurs this Agreement shall be deemed to be an
amendment to any Partnership Agreement to the extent the terms herein conflict
with the terms thereof, including without limitation, terms with respect to
allocations, distributions and the like. If the Closing does not occur, nothing
in this 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 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, (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 a Contributor hereunder) directly, by Direct Contribution,
Merger, Division or otherwise of its direct or indirect interest in such
Partnership or Property 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 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, 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, 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
such Partnership or Property, any consent necessary or desirable under any
Partnership Agreement, 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 and/or other agreements so that no
provision thereof prohibits, restricts, impairs or interferes with any
Conveyance Action, (ii) to admit the Operating Partnership as a substitute
limited partner or general partner of such Partnership upon the contribution of
a limited or general Partnership Interest, respectively, to the Operating
Partnership 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 of which a Partnership Interest of a Contributor
represents a direct or indirect interest, the waiving of any and all rights that
such 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, 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

                                       13
<PAGE>
Partnership or Property or to sell such Contributor's or other person's direct
or indirect interest therein to another partner, rights to sell such
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. Each Contributor further covenants that it will take no action to
enjoin, or seek damages resulting from, any Conveyance Action permitted
hereunder by any holder of a direct or indirect interest in a Partnership or a
Property in which a Partnership Interest of such 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 VI.
                                POWER OF ATTORNEY

      Section 6.1 Grant of Power of Attorney.

            Each 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 such
Contributor, to act in the name, place and stead of such 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 the
Partnership Interests (including, but not limited to the OP Agreement, as it may
be amended or revised, any registration rights agreements and any lock-up
agreements), to the acquisition of interests in any entity that directly or
indirectly owns a certain Property or Partnership Interests by Direct
Contribution, Merger or Division, and to provide information to the Securities
and Exchange Commission and others about the transactions contemplated hereby,
as fully as could such Contributor if personally present and acting (the "Power
of Attorney"). In addition, each of Gilchrist, Rising and Fox hereby also
irrevocably appoints the Attorney-In-Fact as the true and lawful
attorney-in-fact and agent of such individual, to act in the name, place and
stead of such individual to make, execute, acknowledge and deliver any
documents, assignments, notices, requests, instructions, certificates, consents,
letters and other writings in order to contribute any other interests in the
Properties to the Operating Partnership and any interests in any other
properties owned and controlled by Mr. Maguire to Mr. Maguire or his designee,
as applicable, pursuant to the provisions set forth in Section 4.3 hereof (also,
the "Power of Attorney"). Further, each Contributor hereby grants to
Attorney-in-Fact a proxy (the "Proxy") to vote the Partnership Interests on any
matter related to the Formation Transactions presented to any of the
Partnership' 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 any Contributor, by operation of law or by
the occurrence of any other event or events, and if

                                       14
<PAGE>

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. Each
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. Each Contributor hereby authorizes the reliance
of third parties on each of the Power of Attorney and Proxy.

            Each 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 expand Contributor's covenants, representations
or warranties beyond those contemplated by this Agreement and the other
documents and agreements contemplated hereby, and the Attorney-in-Fact shall
hold each Contributor harmless to the extent of any such expansion.

      Section 6.2 Limitation on Liability.

            It is understood that the Attorney-in-Fact (qua Attorney-in-Fact)
assumes no responsibility or liability to any person by virtue of the Power of
Attorney or Proxy granted by the Contributors hereby. Other than as specifically
set forth in this Agreement, 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. Each 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;
provided that this provision shall in no way alter or limit any of the
obligations of the Operating Partnership (other than in its capacity as
Attorney-in-Fact) otherwise set forth in this Agreement. It is understood that
the Attorney-in-Fact may, without breaching any express or implied obligation to
Contributors 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.

            Each 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 such Contributor under this Article 6, and
each 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 VII.
                                  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, other than as
specifically noted, 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, provided that "Arbitrable Claims"
shall not include any claim, dispute or controversy in connection with Section
7.11 hereof, (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 the
rules and procedures of Judicial Arbitration & Mediation Services, Inc.
("JAMS"). Each Arbitrable Claim shall be resolved pursuant to a two-step dispute
resolution process 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 an Arbitrable
      Claim exists, the matter shall be referred to the 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

      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

                                       16

      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.

            Each 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 no Contributor shall 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 such
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
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

      Section 7.4 Governing Law.

of California, without regard to the choice of laws provisions thereof.

      Section 7.5 Amendment; Waiver.

            Any amendment hereto shall be in writing and signed by all parties
hereto. No waiver of any provisions of this Agreement shall be valid unless in
writing and signed by the party against whom enforcement is sought.

      Section 7.6 Entire Agreement.

            This Agreement and all related agreements referred to herein
constitute the entire agreement and supersede conflicting provisions set forth

the parties with respect to the subject matter hereof.

      Section 7.7 Assignability.

            This Agreement shall be binding upon, and shall be enforceable by
and inure to the benefit of, the parties hereto and their respective heirs,
legal representatives, successors and assigns; provided, however, that this
Agreement may not be assigned (except by operation of law) by any party without
the prior written consent of the other parties, and any attempted assignment
without such consent shall be void and of no effect, except that the Operating
Partnership may assign its rights and obligations hereunder to an Affiliate.

      Section 7.8 Titles.

            The titles and captions of the Articles, Sections and paragraphs of
this Agreement are included for convenience of reference only and shall have no
effect on the construction or meaning of this Agreement.

      Section 7.9 Third Party Beneficiary.

            No provision of this Agreement is intended, nor shall it be
interpreted, to provide or create any third party beneficiary rights or any
other rights of any kind in any customer, Affiliate, stockholder, partner,
member, director, officer or employee of any party hereto or any other person or
entity.

      Section 7.10 Severability.

            If any provision of this Agreement, or the application thereof, is
for any reason held to any extent to be invalid or unenforceable, the remainder
of this Agreement and application of such provision to other persons or
circumstances will be interpreted so as reasonably to effect the intent of the
parties hereto. The parties further agree to replace such void or unenforceable
provision of this Agreement with a valid and enforceable provision that will
achieve, to the extent possible, the economic, business and other purposes of
the void or unenforceable provision and to execute any amendment, consent or
agreement deemed necessary or desirable by the parties to effect such
replacement.

      Section 7.11 Equitable Remedies.

            Each Contributor agrees that irreparable damage would occur to the
Operating Partnership in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the Operating Partnership shall be
entitled to an injunction or injunctions to prevent breaches of this Agreement
by Contributor and to enforce specifically the terms and provisions hereof in
any federal or state court located in California (as to which the parties agree
to submit to jurisdiction for the purposes of such action), this being in
addition to any other remedy to which the Operating Partnership is entitled
under this Agreement or otherwise at law or in equity. Notwithstanding the
foregoing, this Agreement shall not bar any equitable remedies otherwise
available to Contributor pursuant to the terms and provisions contained in
Exhibit G.

prior written approval of the Operating Partnership.

      Section 7.13 Time Of The Essence.

            Time is of the essence with respect to all obligations under this
Agreement.

      Section 7.14 Reliance.

and that it has or will consult with its own advisors.

      Section 7.15 Survival.

            It is the express intention and agreement of the parties hereto that
the representations, warranties and covenants of each Contributor and Operating
Partnership set forth in this Agreement shall survive the consummation of the
transactions contemplated hereby; provided, however, that the representations of
each Contributor shall survive only for the period specified in Exhibit D
attached hereto. The provisions of this Agreement that contemplate performance
after the Closing and the obligations of the parties not fully performed at the
Closing shall survive the Closing and shall not be deemed to be merged into or
waived by the instruments of Closing.

                  ARTICLE 2 -- REPRESENTATIONS AND WARRANTIES
                                 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) 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
applicable law, is qualified to do business and is in good standing in each
jurisdiction in

                                   Exhibit D-2
<PAGE>

which the nature of its business or the character of its property make such
qualification necessary.

            2.2 Due Authorization. The execution, delivery and performance of
the Agreement by Contributor has been duly and validly authorized by all
necessary action of Contributor. 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 the Partnership Interests and owns the Partnership Interests free and
clear of any Liens of any nature and has full power and authority to convey the
Partnership Interests to the Operating Partnership free and clear of any Liens,
and, upon delivery of consideration for the 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 hereby. There are no rights,
subscriptions, warrants, options, conversion rights, preemptive rights,
agreements, instruments or understandings of any kind outstanding to which
Contributor is a party (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. No Contributor, nor any entity which is an Affiliate of
any Contributor, has any equity interest, either direct or indirect, in the
Properties, except for the Partnership Interests which are the subject of this
Agreement, or rights or interests in any other assets owned and controlled,
directly or indirectly by Robert F. Maguire III.

            2.5 No Violation. To the Knowledge of Contributor, 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, including the charters and
bylaws, if any, of Contributor, (B) any material agreement, document or
instrument to which Contributor is a party or any document or instrument by
which the Partnership Interests are bound or (C) any term or provision of any
judgment, order, writ, injunction, or decree binding on Contributor (or its
assets or properties), or

                                   Exhibit D-3
<PAGE>

require any approval, consent or waiver of, or make any filing with, any person
or governmental or regulatory authority or under any foreign, federal, state,
local or other law binding on Contributor (or its assets or properties), which
has or may be reasonably expected to have an adverse effect on Contributor, the
Partnership or any of its 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 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 Contributor contained herein. In furtherance
thereof, Contributor represents and warrants to the Operating Partnership and
the Company as follows:

                2.8.1 Investment. Contributor is acquiring the Partnership Units
solely for 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 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.

                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

                                   Exhibit D-4
<PAGE>

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 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 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

                                   Exhibit D-5
<PAGE>

      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 AMENDMENT AND 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 AMENDMENT AND RESTATEMENT OF THE CORPORATION
      SHALL HAVE THE MEANINGS ASCRIBED TO THEM IN THE ARTICLES OF AMENDMENT AND
      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.

            2.9 No Brokers. Neither the Contributor nor any of the Contributor's
respective officers, directors or employees, to the extent applicable, has
employed or made any agreement with any broker, finder or similar agent or any
person or firm which will result in the

                                  Exhibit D-6
<PAGE>

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. 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 immediately following the transfer of its Partnership Interests to
the Operating Partnership.

            2.11 Taxes. To Contributor's Knowledge, no tax lien or other charge
exists or will exist upon consummation of the transactions contemplated hereby
with respect to the Partnership Interests.

            2.12 Litigation. To 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 such Contributor's ability to enter into and perform all of
its obligations under the Agreement.

            2.13 NASD Affiliation. Each Contributor represents severally that
neither it nor any Affiliate of such Contributor is a member, Affiliate of a
member or person associated with a member of the National Association of
Securities Dealers, Inc. ("NASD"). Each 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) use commercially reasonable efforts
to promptly cure any breach of a representation, warranty or covenant of
Contributor hereunder upon its learning of same.

                          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 Contributor hereto shall be liable under this Exhibit D or
the Agreement for monetary

                                  Exhibit D-7
<PAGE>

damages (or otherwise) for breach of any of its representations, warranties and
covenants 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 such 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 all
fees and expenses of Contributor in connection with 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), or at its election, by payment in cash. Any
Partnership Units delivered to an Indemnified Party hereunder shall be valued
based upon the initial public offering price of the Common Stock.
Notwithstanding any provision of the Agreement or this Exhibit D, no Indemnified
Party shall have the right to receive or recover punitive damages against any
Contributor by reason of any breach under or in connection with the Agreement or
any schedule, exhibit, certificate or affidavit or any other document delivered
by such Contributor pursuant to the Agreement, and each Indemnified Party hereby
waives any and all right to receive such punitive damages.

            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 the Contributor, including liabilities or claims to be applied
against 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 the 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

                                   Exhibit D-8
<PAGE>

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 to the extent such payments in the aggregate would exceed the Total
Consideration received by Contributor 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)
and then to any distributions received by Contributor in connection with such
Contributor's Partnership Units. Contributor may make any payments due by it
under this Article 3 in cash.

            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.

            Qualifying Debt: Means indebtedness of the Operating Partnership
that is described in (i), (ii) or (iii) below:

                  (i) In the case of indebtedness secured by any property or
            other asset of the Operating Partnership and not recourse to all of
            the assets of the Operating Partnership, the aggregate amount of all
            indebtedness secured by such property must not exceed seventy-five
            percent (75%) of the fair market value (as determined by the Board
            in its reasonable judgment) of such property at the time that the
            Guarantee Opportunity is first effective. Nonrecourse debt of a
            subsidiary of the Operating Partnership shall be treated as debt of
            the Operating Partnership provided the Operating Partnership
            guarantees such debt and will permit the Contributor to indemnify
            the Operating Partnership from certain losses associated with such
            guarantee on terms which are similar to those set forth in the
            Contributor's Guarantee Agreement and reasonably acceptable to the
            Operating Partnership and the Contributor;

                  (ii) In the case of indebtedness that is recourse to all of
            the assets of the Operating Partnership, the indebtedness is at all
            times the most senior indebtedness recourse to all the assets of the
            Operating Partnership (but there shall not be a prohibition against
            other indebtedness that is pari passu with such indebtedness) and
            the amount of the indebtedness outstanding is at all times at least
            equal to one hundred fifty percent (150%) of the aggregate amount of
            the guarantees provided with respect to such indebtedness; or

                  (iii) Any other indebtedness approved by Robert F. Maguire III
            (or his designee or successor) or the Contributor in each such
            person's sole and absolute discretion.

                                    Exhibit G
<PAGE>

            In addition, debt which satisfies requirement (i) or (ii) above (but
not requirement (iii) above) will not be Qualifying Debt if and when either of
the following occurs:

                  (i) There are other guarantees with respect to the same
            indebtedness that are prior to (i.e., with less economic risk) the
            Guarantee Opportunity provided to the Contributor pursuant hereto;
            or

                  (ii) There are other guarantees with respect to the same
            indebtedness that are pari passu with the Guarantee Opportunity
            provided to the Contributor pursuant hereto, and the amount of all
            such guarantees (including the Contributor's guarantee) exceed
            seventy five percent (75%) of the fair market value of the real
            estate which is security for such indebtedness measured at the time
            any such guarantee is first effective (as determined by the Board in
            its reasonable judgment).

            Notwithstanding the foregoing, there shall be no prohibition on
guarantees of other portions of Qualifying Debt, and the above limitations shall
not apply with respect to any guarantee of such debt by the Company, provided
the Contributor is offered the opportunity to enter into an agreement with the
Company providing that the Contributor will indemnify the Company from certain
losses associated with such debt on terms which are similar to those set forth
in the Contributor's Guarantee Agreement with respect to the debt of the
Operating Partnership.

                ARTICLE 2--SALE RESTRICTION ON PROTECTED PROPERTY

            (a) The Operating Partnership agrees for the benefit of the
Contributor, for the term of the Protected Period, not to directly or indirectly
sell, exchange, or otherwise dispose of any Property or any interest therein
(including without limitation, by way of merger, sale of assets or otherwise)
without the consent of Robert F. Maguire III (or his designee or successor) or
the Contributor, which may be given or withheld in each such person's sole and
absolute discretion.

            (b) Section 2(a) shall not apply to the disposition of a Property if
(i) such disposition qualifies as a like-kind exchange under Section 1031 of the
Code, or an involuntary conversion under Section 1033 of the Code, or other
transaction (including, but not limited to, a contribution of property to any
entity that qualifies for the nonrecognition of gain under Section 721 or
Section 351 of the Code, or a merger or consolidation of the Operating
Partnership with or into another entity that qualifies for taxation as a
"partnership" for federal income tax purposes (a "Successor Partnership")), in
each case that does not result in the recognition of any taxable income or gain
to the Contributor with respect to the Contributor's Partnership Units;
provided, however, that: (1) in the event of a disposition of a Property under
Section 1031 or Section 1033 of the Code or pursuant to another tax deferred
transaction, any property that is acquired in exchange for or as a replacement
for such Property shall thereafter be considered that Property for purposes of
this Exhibit G; (2) if a Property is transferred to another entity in a
transaction in which gain or loss is not recognized, the interest of the
Operating Partnership in such entity shall thereafter be considered that
Property for purposes of this Exhibit G, and if the acquiring entity's
disposition of such Property would cause the Contributor to

                                    Exhibit G
<PAGE>

recognize gain or loss as a result thereof, the transferred Property still shall
be considered that Property for purposes of this Exhibit G; and (3) in the event
of a merger or consolidation involving the Operating Partnership and a Successor
Partnership, the Successor Partnership shall have agreed in writing for the
benefit of the Contributor that all of the restrictions of this Exhibit G shall
apply with respect to each Property; (ii) with respect to the Contributor, the
adjusted taxable basis of the Property has increased in the hands of the
Operating Partnership to fair market value as a result of a taxable disposition
of the Partnership Units received in the Formation Transactions or otherwise,
such that a taxable disposition of such Property by the Operating Partnership
would not result in the allocation of taxable gain to the Contributor pursuant
to Section 704(c) of the Code; or (iii) such disposition is permitted with
respect to all of the "Contributors" under the Robert F. Maguire III
Contribution Agreement pursuant to Section 2(b)(ii) of such agreement.

            (c) Notwithstanding any provision of this Exhibit G, the rights and
remedies of the Contributor for a breach or violation of the covenants set forth
in Section 2(a) shall include a claim for damages (including, without
limitation, incidental, consequential, indirect and special damages, lost
profits, lost revenues and loss of business, whether foreseeable or not) against
the Operating Partnership or any Successor Partnership. All such damages shall
be indemnifiable under Section 3.3 of the Agreement and shall be treated as
"Losses" for purposes thereof. Any claim, dispute or controversy arising out of,
or in connection with, or in relation to the interpretation, performance or
breach of this Exhibit G shall be subject to the provisions of Section 7.1 of
the Agreement.

                      ARTICLE 3--AVAILABILITY OF GUARANTEES

            (a) During the Protected Period, the Operating Partnership shall use
commercially reasonable efforts to make available to the Contributor the
opportunity (a "Guarantee Opportunity") to make a guarantee of Qualifying Debt
of the Operating Partnership pursuant to a Guaranty Agreement in an amount at
least equal to the Guarantee Amount. The Contributor may provide its Guarantee
Agreement provided such agreement shall not expand Contributor's rights
hereunder and shall be subject to the reasonable comments and approval of the
Operating Partnership. During the Protected Period, if Guaranteed Debt is to be
repaid and, immediately after such repayment, the outstanding amount of such
Guaranteed Debt would be less than the Guarantee Amount with respect to such
Guaranteed Debt, the Operating Partnership shall use commercially reasonable
efforts to provide to the Contributor a new Guarantee Opportunity with respect
to Qualifying Debt in an amount equal to the Guaranteed Debt being repaid. In
the event that the Operating Partnership is required to use commercially
reasonable efforts to offer a Guarantee Opportunity pursuant to this Section
3(a), the Operating Partnership will provide the Contributor notice of the type,
amount and other relevant attributes of the Qualifying Debt with respect to
which the Guarantee Opportunity is offered at least ten (10) business days, to
the extent reasonably practicable, but in no event less than five (5) business
days prior to the earlier of the closing of the incurrence of such debt and the
scheduled repayment of the existing Guaranteed Debt. In the event that the
Operating Partnership or a related party repurchases outstanding Guaranteed
Debt, whether or not such debt is retired, the repurchase thereof shall be
treated as a repayment of the Guaranteed Debt for purposes of this Article 3.

                                    Exhibit G
<PAGE>

            (b) The Contributor acknowledges that Guarantee Partners other than
the Contributor have the right to guarantee debt of the Operating Partnership on
terms which are similar to the terms set forth in this Exhibit G. The Operating
Partnership shall use commercially reasonable efforts to offer each Guarantee
Opportunity to the Guarantee Partners (including the Contributor) on a pro rata
basis, based on the proportion of each Guarantee Partner's Guarantee Amount to
the aggregate Guarantee Amounts of all Guarantee Partners, unless the Guarantee
Partners agree to accept Guarantee Opportunities on other than a pro rata basis.

            (c) The Operating Partnership agrees to file its tax returns taking
the position that the Guaranteed Debt is allocable to the Contributor
guaranteeing such debt for purposes of Section 752 of the Code, absent a
determination to the contrary by the Internal Revenue Service. However, the
Operating Partnership makes no representation or warranty to the Contributor
that any guarantee entered into pursuant to Section 3(a) shall be respected for
federal income tax purposes so as to enable the Contributor to be considered to
bear the "economic risk of loss" with respect to the indebtedness thereby
guaranteed by the Contributor for purposes of either Section 752 or Section 465
of the Code.

            (d) Notwithstanding any provision of this Exhibit G, the rights and
remedies of the Contributor for a breach or violation of the covenants set forth
in Section 3(a) shall include a claim for damages (including, without
limitation, incidental, consequential, indirect and special damages, lost
profits, lost revenues, and loss of business, whether foreseeable or not)
against the Operating Partnership or any Successor Partnership. All such damages
shall be indemnifiable under Section 3.3 of the Agreement and shall be treated
as "Losses" for purposes thereof. Any claim dispute or controversy arising out
of, or in connection with, or in relation to the interpretation, performance or
breach of this Exhibit G shall be subject to the provisions of Section 7.1 of
the Agreement.

            (e) The Operating Partnership shall not be obligated to undertake
efforts to maintain any level of indebtedness in excess of the amounts
specifically required to meet the obligations set forth above in this Article 3.

                       ARTICLE 4-- CALCULATION OF DAMAGES

            The Operating Partnership acknowledges that any breach or violation
by it of its obligations under this Exhibit G would cause substantial harm to
the Contributor, and the Operating Partnership agrees that any calculation of
damages payable to the Contributor based solely on the time value of money would
not adequately compensate the Contributor for the harm caused by any breach by
the Operating Partnership of its obligations pursuant to Articles 2 or Article 3
hereof. In addition, for purposes of determining any damages payable by the
Operating Partnership or a Successor Partnership to the Contributor pursuant to
Articles 2 or 3 hereof, the tax effect on the Contributor of any breach or
violation of this Exhibit G by the Operating Partnership shall be considered.

                                    Exhibit G
<PAGE>

                   ARTICLE 5 -- ACKNOWLEDGEMENT OF CONTRIBUTOR

            The Contributor acknowledges that neither Robert F. Maguire III nor
his heirs, estate or other successors by operation of law shall have any duty or
obligation to the Contributor with respect to any decision made or action taken
by any of them under Exhibit F to the Robert F. Maguire III Contribution
Agreement, including, without limitation, consenting to any sale, accepting
indebtedness as "Qualifying Debt" or any other matter. The Contributor further
acknowledges that it shall not have any claim against Robert F. Maguire III or
his successors or assigns for any adverse tax consequences suffered by the
Contributor as a result of any action taken by Robert F. Maguire III or any of
his heirs, estate or other successors by operation of law under Exhibit F to the
Robert F. Maguire III Contribution Agreement.

                             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
<PAGE>

                               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.

  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.

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

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

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

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

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

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.

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
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

                                       16

      Section 7.4 Governing Law.

California, without regard to the choice of laws provisions thereof.

      Section 7.5 Amendment; Waiver.

        Any amendment hereto shall be in writing and signed by all parties
hereto. No waiver of any provisions of this Agreement shall be valid unless in
writing and signed by the party against whom enforcement is sought.

      Section 7.6 Entire Agreement.

        This Agreement and all related agreements referred to herein constitute
the entire agreement and supersede conflicting provisions set forth in all other
prior agreements and understandings, both written and oral, among the parties
with respect to the subject matter hereof.

      Section 7.7 Assignability.

        This Agreement shall be binding upon, and shall be enforceable by and
inure to the benefit of, the parties hereto and their respective heirs, legal
representatives, successors and assigns; provided, however, that this Agreement
may not be assigned (except by operation of law) by any party without the prior
written consent of the other parties, and any attempted assignment without such
consent shall be void and of no effect, except that the Operating Partnership,
may assign its rights and obligations hereunder to an affiliate.

      Section 7.8 Titles.

        The titles and captions of the Articles, Sections and paragraphs of this
Agreement are included for convenience of reference only and shall have no
effect on the construction or meaning of this Agreement.

      Section 7.9 Third Party Beneficiary.

        No provision of this Agreement is intended, nor shall it be interpreted,
to provide or create any third party beneficiary rights or any other rights of
any kind in any customer, affiliate, stockholder, partner, member, director,
officer or employee of any party hereto or any other person or entity.

      Section 7.10 Severability.

        If any provision of this Agreement, or the application thereof, is for
any reason held to any extent to be invalid or unenforceable, the remainder of
this Agreement and application of such provision to other persons or
circumstances will be interpreted so as reasonably to effect the intent of the
parties hereto. The parties further agree to replace such void or unenforceable
provision of this Agreement with a valid and enforceable provision that will
achieve, to the extent possible, the economic, business and other purposes of
the void or

                                       17
<PAGE>

unenforceable provision and to execute any amendment, consent or agreement
deemed necessary or desirable by the Operating Partnership to effect such
replacement.

      Section 7.11 Equitable Remedies.

        Contributor agrees that irreparable damage would occur to the Operating
Partnership in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the Operating Partnership shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement by Contributor
and to enforce specifically the terms and provisions hereof in any federal or
state court located in California (as to which the parties agree to submit to
jurisdiction for the purposes of such action), this being in addition to any
other remedy to which the Operating Partnership is entitled under this Agreement
or otherwise at law or in equity.

      Section 7.12 Confidentiality.

        All press releases or other public communications of any kind relating
to the Public Offering or the transactions contemplated herein, and the method
and timing of release for publication thereof, will be subject to the prior
written approval of the Operating Partnership.

      Section 7.13 Time Of The Essence.

        Time is of the essence with respect to all obligations of Contributor
under this Agreement.

      Section 7.14 Reliance.

        Each party to this Agreement acknowledges and agrees that it is not
relying on tax advice or other advice from the other party to this Agreement,
and that it has or will consult with its own advisors.

      Section 7.15 Survival.

        It is the express intention and agreement of the parties hereto that the
representations, warranties and covenants of Contributor and Operating
Partnership set forth in this Agreement shall survive the consummation of the
transactions contemplated hereby; provided, however, that the representations of
Contributor shall survive only for the period specified in Exhibit D attached
hereto. The provisions of this Agreement that contemplate performance after the
Closing and the obligations of the parties not fully performed at the Closing
shall survive the Closing and shall not be deemed to be merged into or waived by
the instruments of Closing.

      Section 7.16 Notice.

        Any notice to be given hereunder by any party to the other shall be
given in writing by personal delivery or by registered or certified mail,
postage prepaid, return receipt requested, and shall be deemed communicated as

                                 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.

                          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

                               Exhibit D, Page 9

<PAGE>

               (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.
