      having

      such capacity, the “Administrative
      Agent”).

    


    


    W I T N E S S E T H:

    


    WHEREAS,
      MAGUIRE
      PROPERTIES-3161 MICHELSON, LLC,
      a
      Delaware limited liability company (“3161”),
      MAGUIRE PROPERTIES-PARK PLACE PS2, LLC, a Delaware limited liability company
      (“PS2”),
      and
      MAGUIRE PROPERTIES-PARK PLACE PS5, LLC, a Delaware limited liability company
      (“PS5”)
      (individually and collectively, jointly and severally, “Borrower”),
      certain lenders (collectively, the “Lenders”)
      and
      the Administrative Agent are parties to a Construction Loan Agreement dated
      as
      of the date hereof (said Construction Loan Agreement, as modified, amended,
      supplemented and in effect from time to time, being herein called the
“Loan
      Agreement”;
      and,
      except as otherwise herein expressly provided, all terms defined in the Loan
      Agreement are being used herein as defined therein), which Loan Agreement
      provides, among other things, for Loans to be made by the Lenders to Borrower
      in
      an aggregate principal amount not exceeding $240,000,000
      in
      connection with the Project, such Loans to be (i) evidenced by, and repayable
      with interest thereon in accordance with, various Notes to be executed and
      delivered to the respective order of the Lenders and (ii) secured by, among
      other things, the Mortgage;

    


    WHEREAS,
      Guarantor owns one hundred percent (100%) of the ownership in Borrower and
      as a
      result shall directly benefit from the making of the Loans by the Lenders to
      Borrower; and

    


    WHEREAS,
      the Lenders are unwilling to make the Loans unless this Guaranty is executed
      by
      Guarantor and delivered to the Administrative Agent and the Lenders.


    


    NOW,
      THEREFORE, in order to induce the Lenders to make the Loans, and for other
      good
      and valuable consideration, the receipt and sufficiency of which are hereby
      acknowledged, Guarantor hereby agrees to guarantee the Guaranteed Obligations
      (as hereinafter defined) upon the following terms:

    


    Section
      1. Guaranty.

    


    1.01. Guaranteed
      Obligations.
      Guarantor hereby absolutely, unconditionally and irrevocably guarantees to
      the
      Administrative Agent (on behalf of the Lenders) the payment in full of the
      unpaid amount of the Delayed Equity Contribution, which obligations shall be
      paid: (1) when due by Borrower under the Loan Agreement or (2) immediately
      upon
      the occurrence and continuance of an “Event of Default” (as such term is defined
      in the Loan Agreement), 


    
      
         

        
        

      

      
        
        

        
          

        

      

      
        
        

      

    


    


    regardless
      of whether the unpaid amounts of the Delayed Equity Contribution are then due
      by
      Borrower under the Loan Agreement or whether all conditions (including, without
      limitation, any condition requiring the disbursement by the Lenders of Loans
      in
      a like amount) applicable to the payment of such sums by Borrower under the
      Loan
      Agreement have been satisfied (collectively, the "Guaranteed
      Obligations").
      The
      Guarantors hereby further agree that if the Borrower shall fail to pay in full
      when due (whether at stated maturity, by acceleration or otherwise) any of
      the
      Guaranteed Obligations, the Guarantors will immediately pay the same, upon
      demand. All payments by the Guarantors on account of this Guaranty shall be
      paid
      in Dollars. Each and every default under the Loan Documents shall give rise
      to a
      separate cause of action hereunder by the Lenders and separate suits may be
      brought hereunder as each such cause of action arises.

    


    1.02. Obligations
      Unconditional.
      The
      obligations of Guarantor under this Guaranty are absolute and unconditional,
      irrespective of the value, genuineness, validity, regularity or enforceability
      of the Loan Documents, or any substitution, release or exchange of any other
      guaranty of or security for any of the Guaranteed Obligations or the Loans,
      and,
      to the fullest extent permitted by Applicable Law, irrespective of any other
      circumstance whatsoever which might otherwise constitute a legal or equitable
      discharge or defense of a surety or guarantor, it being the intent of this
      Section
      1.02
      that the
      obligations of Guarantor hereunder shall be absolute and unconditional under
      any
      and all circumstances and shall not be released, discharged or in any way
      affected or impaired by any thing, event, happening, matter, circumstance or
      condition whatsoever (whether or not Guarantor shall have any knowledge or
      notice thereof or shall consent thereto). In furtherance of the foregoing and
      without limiting the generality thereof, Guarantor agrees as
      follows:

    


    (a) This
      Guaranty is a guaranty of payment and performance when due and not of
      collection.

    


    (b) The
      obligations of Guarantor hereunder are independent of the obligations of
      Borrower or Guarantor under the other Loan Documents to which they are a party
      and the obligations of any other guarantor of the obligations of Borrower under
      the Loan Documents, and a separate action or actions may be brought and
      prosecuted against Guarantor whether or not any action is brought against
      Borrower or any other guarantors and whether or not Borrower is joined in any
      such action or actions.

    


    (c) Payment,
      performance or completion by Guarantor, or any other guarantor, of a portion,
      but not all, of the Guaranteed Obligations shall in no way limit, affect, modify
      or abridge Guarantor’s liability for any portion of the Guaranteed Obligations
      which has not been paid, performed or completed. Without limiting the generality
      of the foregoing, if the Administrative Agent (or any of the Lenders) is awarded
      a judgment in any suit brought to enforce Guarantor’s covenant to pay, perform
      or complete a portion of the Guaranteed Obligations, such judgment shall not
      be
      deemed to release Guarantor from its covenant to pay, perform or complete the
      portion of the Guaranteed Obligations that is not the subject of such suit,
      and
      such judgment shall not, except to the extent satisfied by Guarantor, limit,
      affect, modify or abridge any other guarantor’s liability in respect of the
      Guaranteed Obligations.

    



    
      
         

        
        

      

      
        2

        
          

        

      

      
        
        

      

    


    


    (d) The
      Administrative Agent on behalf of the Lenders (subject to the terms of the
      Loan
      Documents), upon such terms as it deems appropriate, without notice or demand
      and without affecting the validity or enforceability of this Guaranty or giving
      rise to any reduction, limitation, impairment, discharge or termination of
      Guarantor’s liability hereunder, from time to time may (i) renew, extend,
      accelerate, increase the rate of interest on, or otherwise change the time,
      place, manner or terms of payment or performance under the Loan Documents,
      (ii)
      settle, compromise, release or discharge, or accept or refuse any offer of
      performance with respect to, or substitutions for, the Guaranteed Obligations
      or
      any Loan Document and/or subordinate the payment of the same to the payment
      of
      any other obligations; (iii) request and accept other guaranties of any of
      Borrower’s obligations under the Loan Documents and take and hold security for
      the payment or performance of this Guaranty or the Loan Documents; (iv) release,
      surrender, exchange, substitute, compromise, settle, rescind, waive,
fail
      to perfect its security interest in, alter,
      subordinate or modify, with or without consideration, any security for payment
      or performance of Borrower’s obligations under the Loan Documents, any other
      guaranties of the Loans, or any other obligation of any Person (including any
      other guarantor) with respect to the Loans; (v) enforce and apply any security
      now or hereafter held by or for the benefit of the Administrative Agent and
      the
      Lenders in respect of this Guaranty or the Loans and direct the order or manner
      of sale thereof, and to bid at any such sale, or exercise any other right or
      remedy that the Administrative Agent or the Lenders may have against any such
      security, in each case as in its discretion may determine consistent with any
      applicable security agreement, including foreclosure on any such security
      pursuant to one or more judicial or nonjudicial sales, even though such action
      operates to impair or extinguish any right of reimbursement or subrogation
      or
      other right or remedy of Guarantor against Borrower or any security for the
      Guaranteed Obligations; (vi) apply any payments or recoveries from Borrower,
      Guarantor or any other source, and any proceeds of any security, to the
      Guaranteed Obligations in such manner, order and priority as the Administrative
      Agent may elect (whether or not those obligations are guaranteed by this
      Guaranty or secured at the time of the application); and (vii) exercise any
      other rights available to it under the Loan Documents. The Administrative Agent
      may take any of the foregoing actions upon any terms and conditions as the
      Administrative Agent may elect, without giving notice to Guarantor or obtaining
      the consent of Guarantor and without affecting the liability of Guarantor to
      the
      Administrative Agent or the Lenders.

    


    (e) This
      Guaranty and the obligations of Guarantor hereunder shall be valid and
      enforceable and shall not be subject to any reduction, limitation, impairment,
      discharge or termination for any reason (other than payment in full of the
      outstanding Loans, together with all other amounts due to the Administrative
      Agent and the Lenders under the Loan Documents and the termination of any
      remaining Commitments, or performance in full of the Guaranteed Obligations),
      including, without limitation, the occurrence of any of the following, whether
      or not Guarantor shall have had notice or knowledge of any of them: (i) any
      failure or omission to assert or enforce or agreement or election not to assert
      or enforce, or the stay or enjoining, by order of court, by operation of law
      or
      otherwise, of the exercise or enforcement of, any claim or demand or any right,
      power or remedy (whether arising under the Loan Documents, at law, in equity
      or
      otherwise) with respect to the Guaranteed Obligations or the Loan Documents,
      or
      with respect to any other guaranty of or security for the payment or performance
      of the Guaranteed Obligations or the Loans; (ii) any rescission, waiver,
      amendment or modification of, or any consent to departure from, any of the
      terms
      or provisions (including, without limitation,

    provisions
      relating to events of default) of the Loan Documents, Project Documents, the
      Plans and Specifications, the Construction Schedule, the Budget or of any other
      guaranty or security for the Guaranteed Obligations or the Loans, in each case
      whether or not in accordance with the terms of the Loan Documents or any
      agreement relating to such other guaranty or security; (iii) any Loan Document
      at any time being found to be illegal, invalid or unenforceable with respect
      to
      Borrower; (iv) the application of payments received from any source (other
      than
      payments received pursuant to this Guaranty or the other Loan Documents or
      from
      the proceeds of any security for the Guaranteed Obligations or the Notes except
      to the extent such security also serves as collateral for indebtedness other
      than the Guaranteed Obligations or the Notes) to the payment of indebtedness
      other than the Loans, even though the Administrative Agent and/or the Lenders
      might have elected to apply such payment to any part or all of the Loans; (v)
      the Administrative Agent’s consent to the change, reorganization or termination
      of the ownership structure or existence of Borrower or any of its Affiliates
      and
      to any corresponding restructuring of the Loans, including, without limitation,
      the Guaranteed Obligations; (vi) any failure to perfect or continue perfection
      of a security interest in any collateral which secures any of the Loans,
      including, without limitation, the Guaranteed Obligations; (vii) any defenses,
      set-offs or counterclaims that Borrower may assert against the Administrative
      Agent or any of the Lenders in respect of the Loans, including, without
      limitation, the failure of consideration, breach of warranty, payment, statute
      of frauds, statute of limitations, accord and satisfaction and usury, other
      than
      payment or performance of such obligations under the Loan Documents to the
      extent encompassed in the Guaranteed Obligations; (viii) the acquisition or
      transfer of title to the Project to the Administrative Agent, any of the
      Lenders, any Affiliate of the Lenders or any designee of the Administrative
      Agent or the Lenders (including, without limitation, any purchaser through
      foreclosure, deed in lieu or otherwise); (ix) any act or event which might
      otherwise discharge, reduce, limit or modify Guarantor’s obligations under this
      Guaranty; (x) any waiver, extension, modification, forbearance, delay or other
      act or omission of the Administrative Agent or the Lenders, or their failure
      to
      proceed promptly or otherwise as against Borrower, Guarantor or any security;
      (xi) any action, omission or circumstance which might increase the
      likelihood that Guarantor may be called upon to perform under this Guaranty
      or
      which might affect the rights or remedies of Guarantor as against Borrower;
      or
      (xii) any dealings occurring at any time between Borrower and the Administrative
      Agent or any Lender, whether relating to the Guaranteed Obligations or
      otherwise; and any other thing or omission, or delay to do any other act or
      thing, which may or might in any manner or in any extent vary the risk of
      Guarantor as an obligor in respect of the Guaranteed Obligations.

    


    (f) Whether
      or not Guarantor’s obligations under this Guaranty are subject to any maximum
      dollar amount or any other limitation expressly set forth in this Guaranty,
      Guarantor’s liability under this Guaranty shall not be impaired, reduced or
      affected by reason of Administrative Agent’s and/or any Lender’s application of
      any payments received from any source (i) to the payment of any obligation
      or
      indebtedness of Borrower which is not part of the Guaranteed Obligations, even
      though Administrative Agent and/or any such Lender might lawfully have elected
      to apply such payment to any part or all of the Guaranteed Obligations or (ii)
      to the payment of any of the Guaranteed Obligations (whether or not such payment
      might reduce the outstanding amount of the Guaranteed Obligations to a sum
      that
      is less than the maximum dollar liability, if any, of Guarantor expressly set
      forth herein), unless and until such payment shall have become indefeasible,
      the
      amount so paid shall no longer be available for

    future
      advance under the Loans, and the Loans and all other Guaranteed Obligations
      shall have been indefeasibly paid and performed in full; it being the intention
      of the parties that, notwithstanding any payments applied in reduction of the
      Guaranteed Obligations from any source, Guarantor shall be and remain fully
      liable for the payment of all of the Guaranteed Obligations until the Loans
      and
      all other Guaranteed Obligations have been indefeasibly paid and performed
      in
      full and the Lenders shall have no further or continuing obligation to make
      any
      additional advances of the Loans to Borrower. As used herein, an “indefeasible”
payment shall mean and refer to a payment that is no longer subject to potential
      disaffirmance, impairment, set aside, offset, recoupment, defeasance, recovery,
      disallowance, or recapture pursuant to the provisions of any federal or state
      law, regulation or order applicable to or governing creditors’ rights, including
      without limitation Title 11 of the United States Code, as amended, either by
      reason of the passage of time following such payment or the final judgment
      of a
      court of competent jurisdiction establishing the unassailable right of the
      party
      receiving such payment to retain such payment without reduction, offset, or
      other impairment.

    


    1.03. Waivers
      by Guarantor.
      Guarantor hereby waives, for the benefit of the Administrative Agent and the
      Lenders:

    


    (a) any
      right
      to require the Administrative Agent or the Lenders, as a condition of payment
      or
      performance by Guarantor, to (i) proceed against Borrower, any other guarantor
      of the Guaranteed Obligations or any other Person, (ii) proceed against or
      exhaust any security held from Borrower, any such other guarantor or any other
      Person, (iii) proceed against or have resort to any balance of any deposit
      account or credit on the books of the Lenders in favor of Borrower or any other
      Person, or (iv) pursue any other remedy in the power of the Administrative
      Agent
      or any of the Lenders whatsoever;

    


    (b) any
      defense arising by reason of the incapacity, lack of authority or any disability
      or other defense of Borrower, including, without limitation, any defense based
      on or arising out of the lack of validity or the unenforceability of the
      Guaranteed Obligations or any agreement or instrument related thereto or by
      reason of the cessation of the liability of Borrower from any cause other than
      payment and performance in full of the Guaranteed Obligations;

    


    (c) any
      defense based upon any statute or rule of law which provides that the obligation
      of a surety must be neither larger in amount nor in other respects more
      burdensome than that of the principal;

    


    (d) any
      defense based upon the Administrative Agent’s or any of the Lender’s errors or
      omissions in the administration of the Loans, including, without limitation,
      the
      Guaranteed Obligations;

    


    (e) (i)
      any
      principles or provisions of law, statutory or otherwise, which are or might
      be
      in conflict with the terms of this Guaranty and any legal or equitable discharge
      of Guarantor’s obligations hereunder (other than payment, performance and
      completion of the Guaranteed Obligations or the Loans in full), (ii) the benefit
      of any statute of limitations affecting Guarantor’s liability hereunder or the
      enforcement hereof, (iii) any rights to set-offs, recoupments and counterclaims
      and (iv) promptness, diligence and any requirement that the 


    
      
         

        
        

      

      
        5

        
          

        

      

      
        
        

      

    


    


    Administrative
      Agent or any of the Lenders protect, secure, perfect or insure any security
      interest or lien or any property subject thereto;

    


    (f) notices,
      demands, presentments, protests, notices of protest, notices of dishonor and
      notices of any action or inaction, notices of default under the other Loan
      Documents or any agreement or instrument related thereto, notices of any
      renewal, extension or modification of the Guaranteed Obligations or any
      agreement related thereto, notices of any extension of credit to Borrower and
      any right to consent to any thereof. Guarantor acknowledges that Borrower has
      the right to extend the Maturity Date of the Loans for the First Extension
      Period, the Second Extension Period and the Third Extension Period on the terms
      and conditions set forth in the Loan Agreement; hereby consents to the extension
      of the Maturity Date for each of such periods; and hereby agree that no further
      consent is required from Guarantor in connection with any such extension.
      Guarantor’s obligations hereunder shall not be affected in any way by any such
      extension, and shall continue to apply with respect to all Guaranteed
      Obligations of Borrower under the Loan Documents during any such extension;
      

    


    (g) any
      release, discharge, modification, impairment or limitation of the liability
      of
      Borrower to the Administrative Agent or the Lenders, whether consented to by
      the
      Administrative Agent or the Lenders, consensual or arising by operation of
      law
      or any proceedings in bankruptcy, insolvency or reorganization, or from any
      other cause;

    


    (h) any
      defense based on any rejection or disaffirmance of the Guaranteed Obligations,
      or any part thereof, or any security held therefor, in any such proceedings
      in
      bankruptcy, insolvency or reorganization;

    


    (i) any
      defense based on any action taken or omitted by the Administrative Agent or
      the
      Lenders in any proceedings in bankruptcy or insolvency involving Borrower,
      including any election to have their claim allowed as being secured, partially
      secured or unsecured, any extension of credit by the Administrative Agent or
      the
      Lenders to Borrower in any proceedings in bankruptcy or insolvency, and taking
      and holding by the Administrative Agent or the Lenders of any security for
      any
      such extension of credit; and

    


    (j) any
      defense or benefits that may be derived from or afforded by law which limit
      the
      liability of or exonerate guarantors or sureties, or which may conflict with
      the
      terms of this Guaranty, other than payment or performance of such obligations
      under the Loan Documents.

    


    1.04. Additional
      Waivers.
      Guarantor further agrees as follows:

    


    (a) Guarantor
      agrees that on Borrower’s
      default, the
      Administrative Agent
      may
      elect to foreclose either nonjudicially or judicially against any real or
      personal property security (including, without limitation, the Property) it
      holds for the obligations of Borrower under the Loan Documents, or any part
      thereof, or accept an assignment of any such security in lieu of foreclosure,
      or
      compromise or adjust any part of such obligations, or make any other
      accommodation with Borrower
      or
      Guarantor, or exercise any other remedy against Borrower
      or any
      security. No such action by the
      Administrative Agent
      will
      release or limit the liability of 


    
      
         

        
        

      

      
        6

        
          

        

      

      
        
        

      

    


    


    Guarantor
      to the
      Administrative Agent or any Lender,
      who
      shall remain liable under this Guaranty after the action, even if the effect
      of
      that action is to deprive Guarantor of the right to collect reimbursement from
      Borrower
      or any
      other person for any sums paid to the
      Administrative Agent
      or any
      Lender, or Guarantor’s rights of subrogation, contribution, or indemnity against
Borrower
      or any
      other person. Without limiting the foregoing, it is understood and agreed that
      on any foreclosure or assignment in lieu of foreclosure of any security held
      by
the
      Administrative Agent,
      such
      security will no longer exist, and that any right that Guarantor might otherwise
      have, on full payment of the obligations of Borrower under the Loan Documents
      by
      Guarantor, to participate in any such security or to be subrogated to any rights
      of the
      Administrative Agent
      or any
      Lender with respect to any such security will be nonexistent; nor shall
      Guarantor by deemed to have any right, title, interest or claim under any
      circumstances in or to any real or personal property held by the
      Administrative Agent, any Lender
      or any
      third party following any foreclosure or assignment in lieu of foreclosure
      of
      any such security.

    


    (b) Guarantor
      understands and acknowledges that if the
      Administrative Agent
      forecloses judicially or nonjudicially against any real property security for
      the Borrower’s
      obligations, such foreclosure could impair or destroy any right or ability
      that
      Guarantor may have to seek reimbursement, contribution, or indemnification
      for
      any amounts paid by such Guarantor under this Guaranty. Guarantor further
      understands and acknowledges that in the absence of this waiver such potential
      impairment or destruction of Guarantor’s rights, if any, may entitle such
      Guarantor to assert a defense to this Guaranty based on Code of Civil Procedure
      §580d as interpreted in Union
      Bank v. Gradsky,
      (1968)
      265 CA 2d 40, 71 CR 64, on the grounds, among others, that a lender
      should
      be estopped from pursuing a guarantor because the lender’s
      election to foreclose may impair or destroy the subrogation, reimbursement,
      contribution, or indemnification rights of the guarantor. By execution of this
      Guaranty, Guarantor intentionally, freely, irrevocably, and unconditionally:
      (i)
      waives and relinquishes that defense and agrees that such Guarantor will be
      liable under this Guaranty even though the
      Administrative Agent
      had
      foreclosed judicially or nonjudicially against any real or personal property
      collateral for Borrower’s
      obligations; (ii) agrees that such Guarantor will not assert that defense in
      any
      action or proceeding in which the
      Administrative Agent
      or any
      Lender seeks to enforce this Guaranty; and (iii) acknowledges and agrees that
      the rights and defenses waived by such Guarantor in this Guaranty include any
      right or defense that such Guarantor may have or be entitled to assert based
      on
      or arising out of any one or more of Code of Civil Procedure §§580a, 580b, 580d,
      or 726, or Civil Code §2848. 

    


    (c) Guarantor
      intentionally, freely, irrevocably and unconditionally waives and relinquishes
      all rights which may be available to it under any provision of California law
      or
      under any California judicial decision, including, without limitation, Section
      580a and 726(b) of the California Code of Civil Procedure, to limit the amount
      of any deficiency judgment or other judgment which may be obtained against
      such
      Guarantor under this Guaranty to not more than the amount by which the unpaid
      obligations of Borrower under the Loan Documents guaranteed hereby plus all
      other indebtedness due from Borrower
      under
      the Loan
      Documents
      exceeds
      the fair market value or fair value of any real or personal property securing
      said obligations of Borrower under the Loan Documents and any other indebtedness
      due from Borrower
      under
      the Loan
      Documents,
      including, without limitation, all rights to an appraisement of, judicial or
      other hearing on, or other determination of the value of said property.
      Guarantor acknowledges and 


    
      
         

        
        

      

      
        7

        
          

        

      

      
        
        

      

    


    


    agrees
      that, as a result of the foregoing waiver, the
      Administrative Agent
      and the
      Lenders may be entitled to recover from such Guarantor an amount which, when
      combined with the value of any real or personal property foreclosed upon by
      the
      Administrative Agent
      (or the
      proceeds of the sale of which have been received by the
      Administrative Agent or the Lenders)
      and any
      sums collected by the
      Administrative Agent
      and the
      Lenders from Borrower
      or other
      persons, might exceed the amount of the obligations of Borrower under the Loan
      Documents guaranteed hereby plus all other indebtedness due from Borrower
      under
      the Loan
      Documents.

    


    (d) Guarantor
      waives all rights and defenses that Guarantor may have because Borrower’s debt
      is secured by real property; this means, among other things: (i) the
      Administrative Agent and the Lenders may collect from Guarantor without first
      foreclosing on any real or personal property collateral pledged by Borrower;
      and
      (ii) if the Administrative Agent or the Lenders foreclose on any real property
      collateral pledged by Borrower: (A) the amount of the Obligations may be
      reduced only by the price for which that collateral is sold at the foreclosure
      sale, even if the collateral is worth more than the sale price; and (B) the
      Administrative Agent and the Lenders may collect from Guarantor even if the
      Administrative Agent, by foreclosing on the real property collateral, has
      destroyed any right Guarantor may have to collect from Borrower. This is an
      unconditional and irrevocable waiver of any rights and defenses Guarantor may
      have because the Guaranteed Obligations are secured by real property. These
      rights and defenses include, but are not limited to, any rights or defenses
      based upon Section 580a, 580b, 580d, or 726 of the California Code of Civil
      Procedure. Guarantor specifically waives any right to a fair value hearing,
      and
      any and all other rights it may have under Section 580a of the California Code
      of Civil Procedure.

    


    (e) Guarantor
      waives all rights and defenses arising out of an election of remedies by the
      Administrative Agent and the Lenders, even though that election of remedies,
      such as a nonjudicial foreclosure with respect to security for the Guaranteed
      Obligations, has destroyed Guarantor’s rights of subrogation and reimbursement
      against the principal by the operation of Section 580d of the California Code
      of
      Civil Procedure or otherwise.

    


    (f) Guarantor
      waives all rights and defenses which might otherwise be available to Guarantor
      under any guarantor, suretyship or other defenses under any law of the State
      of
      California, including, without limitation, California Civil Code Sections 2787
      to 2855, inclusive, 2899 and 3433.

    


    (g) Guarantor
      agrees that if the maturity of any Guaranteed Obligation is accelerated by
      bankruptcy, insolvency or otherwise, such maturity shall also be deemed
      accelerated for the purpose of this Guaranty without demand on or notice to
      Guarantor, and Guarantor hereby waives any such demand or notice.

    


    1.05. Reinstatement.
      The
      obligations of Guarantor under this Section
      1
      shall be
      automatically reinstated if and to the extent that for any reason any payment
      by
      or on behalf of Borrower or Guarantor in respect of the Guaranteed Obligations
      is rescinded or must be otherwise restored by any holder of the Guaranteed
      Obligations, whether as a result of any proceedings in bankruptcy or insolvency
      or otherwise; and Guarantor agrees that it will indemnify the Administrative
      Agent and the Lenders on demand for all reasonable costs and 


    
      
         

        
        

      

      
        8

        
          

        

      

      
        
        

      

    


    


    expenses
      (including, without limitation, reasonable fees and expenses of counsel)
      incurred by the Administrative Agent or any of the Lenders in connection with
      such rescission or restoration, including any such costs and expenses incurred
      in defending against any claim alleging that such payment constituted a
      preference, fraudulent transfer or similar payment under any bankruptcy,
      insolvency or similar law.

    


    1.06. Guarantor’s
      Rights of Subrogation, Contribution, Etc.
      Guarantor hereby waives, until the later of (a) the Guaranteed Obligations
      shall
      have been indefeasibly paid, performed and completed in full and (b) the Loans
      and all other amounts due under the Loan Documents have been indefeasibly paid
      in full and the Commitments have been terminated, any claim, right or remedy,
      direct or indirect, that Guarantor now has or may hereafter have against
      Borrower or any of its assets in connection with this Guaranty or the
      performance by Guarantor of its obligations hereunder, in each case whether
      such
      claim, right or remedy arises in equity, under contract, by statute, under
      common law or otherwise and, including without limitation, (i) any right of
      subrogation, reimbursement or indemnification that Guarantor now has or may
      hereafter have against Borrower, (ii) any right to enforce, or to participate
      in, any claim, right or remedy that the Administrative Agent or the Lenders
      now
      have or may hereafter have against Borrower, and (iii) any benefit of, and
      any
      right to participate in, any collateral or security now or hereafter held by
      or
      on behalf of the Administrative Agent and/or the Lenders. In addition, until
      the
      Loans have been indefeasibly paid in full and all Commitments have been
      terminated, Guarantor shall withhold exercise of any right of contribution
      which
      Guarantor may have against any other guarantor of the Loans or Guaranteed
      Obligations. Guarantor further agrees that, to the extent the waiver or
      agreement to withhold the exercise of its right of subrogation, reimbursement,
      indemnification and contribution as set forth herein is found by a court of
      competent jurisdiction to be void or voidable for any reason, any rights of
      subrogation, reimbursement or indemnification Guarantor may have against
      Borrower or against any collateral or security, and any rights of contribution
      Guarantor may have against any other guarantor, shall be junior and subordinate
      to any rights the Administrative Agent and/or any of the Lenders may have
      against Borrower, to all right, title and interest the Administrative Agent
      and/or any of the Lenders may have in any such collateral or security, and
      to
      any right the Administrative Agent and/or any of the Lenders may have against
      such other guarantor. If any amount shall be paid to Guarantor on account of
      any
      such subrogation, reimbursement, indemnification or contribution rights at
      any
      time when (A) all Guaranteed Obligations shall not have been paid, performed
      and
      completed in full, (B) all outstanding Loans and all other amounts due under
      the
      Loan Documents shall not have been paid in full or (C) the Commitments shall
      not
      have been fully terminated, such amount shall be held in trust for the
      Administrative Agent (on behalf of the Lenders) and shall forthwith be paid
      over
      to the Administrative Agent (on behalf of the Lenders) to be credited and
      applied against the Guaranteed Obligations, whether matured or unmatured, in
      accordance with the terms hereof.

    


    1.07. Subordination
      of Other Obligations.
      Any
      indebtedness of Borrower now or hereafter held by Guarantor is hereby
      subordinated in right of payment to the Loans and to the payment, performance
      and completion of the Guaranteed Obligations, and any such indebtedness of
      Borrower to Guarantor collected or received by Guarantor after an Event of
      Default (including any Event of Default under any of the Loan Documents) has
      occurred and is continuing shall be held in trust for the Administrative Agent
      (on behalf of the Lenders) and shall forthwith be paid 


    
      
         

        
        

      

      
        9

        
          

        

      

      
        
        

      

    


    


    over
      to
      the Administrative Agent (on behalf of the Lenders) to be credited and applied
      against the Guaranteed Obligations but without affecting, impairing or limiting
      in any manner the liability of Guarantor under any other provision of this
      Guaranty.

    


    1.08. Remedies.

    


    (a) Guarantor
      agrees that, as between Guarantor and the Administrative Agent and the Lenders,
      the obligations of Borrower under any of the Loan Documents may be declared
      to
      be forthwith due and payable as provided in the Loan Documents (and shall be
      deemed to have become automatically due and payable in the circumstances therein
      provided) for purposes of Section
      1.01
      hereof
      notwithstanding any stay, injunction or other prohibition preventing the
      enforcement of such obligations as against Borrower; and that, in the event
      of
      such declaration (or such obligation being deemed to have become automatically
      due and payable), such obligations (whether or not enforceable as against
      Borrower) to the extent they constitute part of the Guaranteed Obligations
      shall
      forthwith become due by Guarantor for purposes of Section
      1.01
      hereof.
      The Administrative Agent (on behalf of the Lenders) may bring and prosecute
      a
      separate action against Guarantor to enforce the Guaranteed Obligations under
      this Guaranty, whether or not any action is brought against Borrower or any
      other Person and whether or not Borrower or any other Person is joined in any
      such action or actions.

    


    (b) All
      of
      the remedies set forth in this Guaranty and/or provided for in any of the Loan
      Documents or at law or in equity shall be equally available to the
      Administrative Agent (on behalf of the Lenders), and the choice by the
      Administrative Agent (on behalf of the Lenders) of one such alternative over
      another shall not be subject to question or challenge by Guarantor or any other
      Person, nor shall any such choice be asserted as a defense, setoff, or failure
      to mitigate damages in any action, proceeding, or counteraction by the
      Administrative Agent (on behalf of the Lenders) to recover or seek any other
      remedy under this Guaranty, nor shall any such choice preclude the
      Administrative Agent (on behalf of the Lenders) from subsequently electing
      to
      exercise a different remedy.

    


    1.09. Default
      Interest.
      Guarantor hereby agrees that in the event it shall fail to pay in full any
      amount owing by it hereunder within five (5) Business Days following delivery
      of
      a written demand by the Administrative Agent for payment of such amount, it
      shall be obligated to pay interest at the Default Rate in respect of any such
      amount for each day during the period from and including the due date thereof
      to
      but excluding the date the same shall be paid in full, such interest to be
      payable upon demand of the Administrative Agent; provided,
      however,
      that
      payment under this Section
      1.09
      shall
      not be in duplication of any payment made by Guarantor or Borrower pursuant
      to
      the Loan Documents.

    


    1.10. Continuing
      Guaranty.
      This
      Guaranty is a continuing guaranty and shall remain in effect until the earlier
      of (a) all of the Guaranteed Obligations shall have been paid, performed and
      completed in full or (b) the Loans and all other amounts due under the Loan
      Documents have been paid in full and the Commitments have been terminated;
      including, without limitation, in either case, the payment of any and all
      expenses which might be incurred by the Administrative Agent or the Lenders
      in
      enforcing any of their rights hereunder (which 


    
      
         

        
        

      

      
        10

        
          

        

      

      
        
        

      

    


    


    expense
      shall be included within the meaning of Guaranteed Obligations) and all interest
      due pursuant to Section
      1.09.

    


    1.11. Enforceability;
      Etc.
      The
      Administrative Agent (on behalf of the Lenders or any other or subsequent
      beneficiary of this Guaranty, but subject to the terms of Section
      14.3
      of the
      Loan Agreement) may enforce the Guaranteed Obligations.

    


    1.12. Assumption
      of Risk Regarding Borrower’s Financial Condition.
      Before
      signing this Guaranty, Guarantor investigated the financial condition and
      business operations of Borrower,
      the
      Project encumbered by the Mortgage, and such other matters as Guarantor deemed
      appropriate to assure itself of Borrower’s
      ability to discharge its obligations under the Loan
      Documents.
      Guarantor assumes full responsibility for keeping fully informed of the
      financial condition of Borrower and all other circumstances affecting Borrower’s
      ability to perform its obligations to the Administrative Agent and the Lenders,
      and agrees that neither the Administrative Agent nor any Lender will have any
      duty to report to Guarantor any information which it receives about Borrower’s
      financial condition or any circumstances bearing on Borrower’s ability to
      perform.

     

    Section
      2. Representations
      and Warranties.
      Guarantor hereby represents and warrants to the Lenders and the Administrative
      Agent that:

    


    2.01. Existence.
      Guarantor (i) is a limited partnership duly organized and validly existing
      under
      the laws of the State of Maryland; (ii) has all requisite partnership
      power, and has all material governmental licenses, authorizations, consents
      and
      approvals necessary to own its assets and carry on its business as now being
      or
      as proposed to be conducted; and (iii) is qualified to do business in all
      jurisdictions in which the nature of the business conducted by it makes such
      qualification necessary.

    


    2.02. No
      Breach.
      The
      execution and delivery of this Guaranty, the consummation of the transactions
      herein contemplated, and Guarantor’s compliance with the terms and provisions
      hereof will not conflict with or result in a breach of, or require any consent
      under, the organizational documents pursuant to which Guarantor is organized,
      or
      any Applicable Law or regulation, or any order, writ, injunction or decree
      of
      any court or Governmental Authority or agency, or any agreement or instrument
      to
      which Guarantor is a party or by which it is bound or to which it is subject,
      or
      constitute a default under any such agreement or instrument, or result in the
      creation or imposition of any lien upon any of the revenues or assets of
      Guarantor pursuant to the terms of any such agreement or
      instrument.

    


    2.03. Action.
      Guarantor has all necessary organizational power and authority, as the case
      may
      be, to execute, deliver and perform its obligations under this Guaranty; the
      execution, delivery and performance by Guarantor of this Guaranty have been
      duly
      authorized by all necessary organizational action, as the case may be, on its
      part; and this Guaranty has been duly and validly executed and delivered by
      Guarantor and constitutes its legal, valid and binding obligation, enforceable
      in accordance with its terms, subject to applicable bankruptcy, insolvency,
      reorganization, moratorium or other similar laws of general application
      affecting the enforcement of creditors’ rights. 

    



    
      
         

        
        

      

      
        11

        
          

        

      

      
        
        

      

    


    


    2.04. Approvals.
      No
      authorizations, approvals or consents of, and no filings or registrations with,
      any governmental or regulatory authority or agency (other than such
      authorizations, approvals or consents already obtained) are necessary for the
      execution, delivery or performance by Guarantor of this Guaranty or for the
      validity or enforceability hereof.

    


    2.05. Other
      Agreements.
      Guarantor is not a party to any agreement or instrument or subject to any court
      order, injunction, permit or restriction which could reasonably be expected
      to
      materially and adversely affect Guarantor’s ability to perform its obligations
      hereunder.

    


    2.06 Financial
      Condition.
      The
      consolidated balance sheet with respect to Guarantor as of June 30, 2006,
      heretofore furnished to the Administrative Agent and the Lenders, is materially
      complete and correct and fairly presents the financial condition of Guarantor
      as
      at the date of such balance sheet. As of the date of such balance sheet,
      Guarantor had no material contingent liabilities, liabilities for taxes, unusual
      forward or long-term commitments or unrealized or anticipated losses from any
      unfavorable commitments, except as referred to or reflected or provided for
      in
      said balance sheet. Since the date of such balance sheet, there has been no
      material adverse change in Guarantor’s financial condition.

    


    2.07. Litigation.
      Except
      as disclosed to the Administrative Agent and the Lenders in writing prior to
      the
      date of this Guaranty, there are no legal or arbitration proceedings or any
      proceedings by or before any Governmental Authority, now pending or (to the
      knowledge of Guarantor) threatened against Guarantor which, if adversely
      determined, could have a material adverse effect on Guarantor’s ability to enter
      into or comply with its obligations hereunder.

    


    2.08. Taxes.
      Guarantor has filed all Federal income tax returns and all other material tax
      returns and information statements that are required to be filed by it and
      has
      paid all taxes due pursuant to such returns or pursuant to any assessment
      received by Guarantor.

    


    Section
      3. Covenants.
      Guarantor covenants to each Lender and the Administrative Agent that, until
      the
      payment, performance and completion in full of the Guaranteed
      Obligations:

    


    3.01. Existence,
      Etc.
      Guarantor will preserve and maintain its corporate, limited liability company
      or
      partnership existence, as the case may be, and all of its other material rights,
      privileges and franchises necessary for the maintenance of its existence and
      the
      conduct of its affairs; and comply with the requirements of all applicable
      laws,

      with
      the requirements of Section

      hereof
      on the date of such financial statements; and (iii) that such officer has no

    Notwithstanding

      treatment or amount of such item in accordance with GAAP for Guarantor; and
      (iii) there is no change in the structure or ownership of Guarantor that the
      Administrative Agent concludes in reasonable discretion would require the

      the
      Guarantor.

      and as
      otherwise provided under this Section
      3.04,
      for so
      long as Guarantor maintains a primary credit facility under which Guarantor
      obtains financing for its general corporate purposes (a “Primary
      Credit Facility”)
      that
      includes financial covenants which are based upon the value of the assets of
      Guarantor, and such assets are valued based upon the capitalization of income

      replaced by a Primary Credit Facility that includes financial covenants which
      are based upon the value of the assets of Guarantor, and such assets are valued
      based upon the capitalization of income streams from the assets of Guarantor
      in
      accordance with certain capitalization rates, the Administrative Agent agrees,
      that the capitalization rates utilized in determining the valuation of the
      different classes of assets, the values of which are to be included within
      the
      Total Asset Value of Guarantor, shall be valued based upon the capitalization
      rates set forth in such amended Revolver Credit Agreement or then effective
      Primary Credit

    Facility,
      as the case may be; and (B) in the event that the Revolver Credit Agreement
      or
      the then effective Primary Credit Facility is amended to delete the financial
      covenants which are based upon the value of the assets of Guarantor, and such
      assets are no longer valued based upon the capitalization of income streams
      from
      the assets of Guarantor in accordance with certain capitalization rates, or
      the
      Revolver Credit Agreement or the then effective Primary Credit Facility is
      terminated and not replaced by a new Primary Credit Facility containing
      financial covenants which are based upon the value of the assets of Guarantor,
      and such assets are valued based upon the capitalization of income streams
      from
      the assets of Guarantor in accordance with certain capitalization rates, as
      the
      case may be, the Administrative Agent shall continue to value the Total Asset
      Value of Guarantor based upon the capitalization rates set forth in the
      terminated Revolver Credit Agreement or last effective Primary Credit Facility,
      as the case may be.

      by assignment, gift or creation of a trust or otherwise), other than for fair

      or
      otherwise satisfy at or before maturity or before they become delinquent, as
      the
      case may be, all its recourse Debt obligations of whatever nature, where such
      failure to so pay, discharge or satisfy would, in the aggregate with all such
      failures, reasonably be expected to have a Material Adverse Effect, except
      where
      the amount or validity thereof is currently being contested in good faith by
      appropriate proceedings and reserves in conformity with GAAP with respect
      thereto have been provided on the books of Guarantor.

      order and condition, casualty, condemnation and ordinary wear and tear excepted,
      and promptly repair or replace such property following any damage thereto in
      each case where the failure to do so would, in the aggregate, reasonably be

      of the
      Loan Agreement, maintain, with financially sound and reputable insurance
      companies, insurance in such amounts and against such risks as are customarily

      continuing failure; or

      occurrence of an “Event of Default” under (as such term is defined in) any other
      guaranty delivered by Guarantor to the Administrative Agent for the benefit
