                                     FORM OF
                               PURCHASE AGREEMENT

            This Purchase Agreement (hereinafter referred to as this "Purchase
Agreement") is entered into as of June __, 2003, among Maguire Properties, L.P.,
a Maryland limited partnership ("Buyer"), RECP Library LLC, a Delaware limited
liability company ("Seller") and New BHE, LLC, a Delaware limited liability
company (the "Company"), Bunker Hill Equity, LLC, a Delaware limited liability
company ("Bunker Hill"), Maguire Partners BGHS, LLC, a Delaware limited
liability company ("BGHS"), Maguire Partners-Hope Place, Ltd., a California
limited partnership ("Hope Place").

                                    RECITALS

            A. Robert F. Maguire III, Maguire Partners and their affiliates are
currently engaged in the process of consolidating the ownership of a portfolio
of office and other properties (the "Participating Properties") located in
Southern California, including the property commonly known as the Library Tower
(the "Property"), through a series of transactions in which Robert F. Maguire
III, Maguire Partners, their affiliates and unrelated third parties shall
contribute the direct or indirect interests in the Participating Properties (the
"Property Interests") or the direct or indirect interests in certain limited
partnerships and certain limited liability companies (collectively, the
"Participating Partnerships"), which currently own, directly or indirectly, the
Participating Properties, to Buyer (the "Formation Transactions"). The Formation
Transactions relate to the proposed initial public offering of the shares of
common stock (the "Offering") of Maguire Properties, Inc., a Maryland
corporation (the "REIT"), the general partner of Buyer, which intends to operate
as a self-administered and self-managed real estate investment trust.

            B. Seller holds a preferred equity interest in the Company (all of
Seller's interest in the Company, including without limitation, all of its
voting rights and interests in the capital, profits and losses of the Company or
any property distributable therefrom are hereinafter collectively referred to as
the "Preferred Equity Interest") pursuant to that certain Limited Liability
Company Agreement of the Company dated _______, 2003 (the "Company Operating
Agreement") between Seller and Bunker Hill. Seller previously held a preferred
equity interest in Bunker Hill pursuant to that certain Limited Liability
Company Agreement of Bunker Hill dated March 27, 2002 (the "Bunker Hill
Operating Agreement," and together with the Company Operating Agreement, the
"Operating Agreements") between Seller, BGHS, Hope Place and Kim E. Lutthans, as
a special member. Robert F. Maguire III, BGHS, Hope Place and Seller also
entered into that certain Option Agreement dated March 27, 2002 (the "Option
Agreement") in connection with the Bunker Hill Operating Agreement whereby
Seller was granted certain put rights and BGHS and Hope Place were granted
certain call rights with respect to Seller's preferred equity interest in Bunker
Hill. Seller's preferred equity interest in Bunker Hill was redeemed by Bunker
Hill in exchange for the Preferred Equity Interest pursuant to that certain
Redemption Agreement between Bunker Hill and Seller dated ________, 2003 (the
"Redemption Agreement").
<PAGE>
            C. In connection with the Formation Transactions, Buyer desires to
acquire from Seller, and Seller desires to sell to Buyer, on the terms and
conditions set forth herein, all of Seller's right, title and interest to the
Preferred Equity Interest.

            D. Seller acknowledges that Buyer may decide that, rather than
acquiring all of the direct and indirect interests in the entity that owns the
Property or acquiring the Preferred Equity Interest by direct transfer, it is
more desirable for Buyer to acquire the Property by a direct contribution of the
Property from the entity that owns the Property (a "Direct Contribution"), or by
a merger of a partnership with and into Buyer (a "Merger"), or to divide a
partnership into more than one partnership to facilitate the Formation
Transactions (a "Division"); and Seller desires to give Buyer the right, in
Buyer's sole discretion, to engage in any Direct Contribution, Merger or
Division concurrently with or immediately prior to the purchase by Buyer of the
Preferred Equity Interest on the terms and conditions described herein without
the need to seek any further consent or action of the Seller and irrevocably
consents to such action as set forth in Section 5.4.

            NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Buyer, Seller and the Company
agree as follows:

                                   ARTICLE I.

Seller hereby agrees to sell, all right, title and interest of Seller in the
Preferred Equity Interest (the "Purchase") upon the terms and conditions set
forth herein.

            1.2 Purchase Price. The purchase price for the Preferred Equity
Interest will be [$_________] (the "Purchase Price"). Buyer and Seller agree
that the Purchase Price constitutes full consideration for the Purchase.

            1.3 Consent of the Company. The Company hereby consents to the
Purchase by Buyer upon the terms and conditions set forth herein.

            1.4 Termination of this Agreement. In the event that the Purchase
does not occur, Seller agrees not to treat this Agreement as a "Call Notice"
under the Option Agreement, and specifically that the events set forth in
Sections 3.1(c)(ii), (iii) and (iv) of the Option Agreement shall not be
triggered; provided, however, that Seller shall remain entitled to payment of
costs as set forth in Section 3.1(c)(i) of the Option Agreement.

                                  ARTICLE II.
                              PURCHASE AND CLOSING

            2.1 Purchase and Sale. Seller hereby sells, transfers, assigns, and
conveys to Buyer, and Buyer hereby purchases, for the Purchase Price all right,
title and interest of Seller in the Preferred Equity Interest free and clear of
all Liens. For purposes of this Purchase Agreement, "Liens" shall mean any lien
(statutory or other), pledge, hypothecation, assignment, preference, priority,
security interest, or any other encumbrance or charge on or affecting the


                                       2
<PAGE>
Preferred Equity Interest or the preferred equity interest that Seller
previously held in Bunker Hill.

            2.2 Closing. The parties are hereby delivering the following closing
documents, (i) an Assignment and Assumption Agreement substantially in the form
attached hereto as Exhibit A, (ii) any other documents reasonably necessary to
assign, transfer and convey the Preferred Equity Interest, and (iii) an
affidavit from Seller, stating under penalty of perjury, Seller's United States
Taxpayer Identification Number and that Seller is not a foreign person pursuant
to Section 1445(b)(2) of the Internal Revenue Code of 1986, as amended (the
"Code") and a comparable affidavit satisfying California and any other state
withholding requirements, in the forms attached hereto as Exhibit B. Buyer is
hereby delivering to Seller a cash amount equal to the Purchase Price for the
Preferred Equity Interest in consideration for the sale, transfer, assignment
and conveyance of the Preferred Equity Interest.

            2.3 Option Termination. The Option Agreement, if not earlier
terminated, is hereby terminated and of no further force and effect. Bunker
Hill, BGHS, Hope Place and Seller hereby consent to the termination of the
Option Agreement, including the termination of all put and call rights contained
therein with respect to Seller's preferred equity interest in Bunker Hill
contained therein.

            2.4 Taxes. Buyer agrees to pay all transfer taxes arising from the
sale of the Preferred Equity Interest pursuant to the transfer of the Preferred
Equity Interest hereunder. Buyer and Seller (or any other transferor as provided
hereunder) each agree and consent to treat this transaction as the sale of the
Preferred Equity Interest (or interests of such other transferor) with the tax
consequences set forth in Section 741 of the Code.

            2.5 Further Assurances. Seller and Buyer will, from time to time,
execute and deliver to the other party all such other and further instruments
and documents and take or cause to be taken all such other and further action as
Seller and Buyer may reasonably request in order to effect the transactions
contemplated by this Purchase Agreement, including instruments or documents
reasonably necessary to effect and evidence the conveyance of the Preferred
Equity Interest in accordance with the terms of this Purchase Agreement. Seller
has represented herein that it has no equity interest, either direct or
indirect, in the Property, the Company or Bunker Hill, except for the Preferred
Equity Interest which is the subject of this Purchase Agreement. In the event
that this representation is at any time determined to be inaccurate, Seller
agrees to execute and deliver to Buyer all such other and further instruments
and documents and take or cause to be taken all such other and further action as
Buyer may reasonably request in order to document the transfer hereof of the
Preferred Equity Interest to the Buyer.

                                  ARTICLE III.
                    REPRESENTATIONS, WARRANTIES AND COVENANTS

                     CERTIFICATION OF NON-FOREIGN STATUS(1)

Section 1445 of the Internal Revenue Code of 1986, as amended provides that a
transferee of a United States real property interest must withhold tax if the
transferor is a foreign person. To inform Maguire Properties, L.P., a Maryland
limited partnership ("Buyer") that the withholding of tax is not required upon
the sale of the Preferred Equity Interest by RECP Library LLC, a Delaware
limited liability company (the "Seller") to the Buyer in exchange for the
Purchase Price, the undersigned hereby certifies the following on behalf of the
Seller:

      1.  The Seller is not a foreign corporation, foreign partnership,
foreign trust or foreign estate (as those terms are defined in the Code and
the Treasury Regulations promulgated thereunder);

      2.  The Seller's employer identification number is ______________; and

      3.  The Seller's office address is:

            2121 Avenue of the Stars
            Los Angeles, California 90067

      The undersigned understands that this certification may be disclosed to
the Internal Revenue Service by the Buyer and that any false statement contained
herein could be punishable by fine, imprisonment or both.

      Under penalties of perjury, I declare that I have examined this
certification and, to the best of my knowledge and belief, it is true, correct
and complete, and I further declare that I have authority to sign this document
on behalf of the Seller.
