               (3) Upon receipt of a Notice of Borrowing in proper form requesting LIBOR Advances under subparagraph (1) or (2) above, Administrative Agent shall deliver a copy thereof (by facsimile) to each Lender by noon (San Francisco time) on the same day of Administrative Agent’s receipt thereof and shall determine the LIBOR Rate applicable to the Interest Period for such LIBOR Advances, and shall, two (2) Business Days prior to the beginning of such Interest Period, give (by facsimile) a Fixed Rate Notice in respect thereof to Borrower and the Lenders; provided, however, that failure to give such notice to Borrower shall not affect the validity of such rate. Each determination by Administrative Agent of the LIBOR Rate shall be conclusive and binding upon the parties hereto in the absence of manifest error.

               (4) If Borrower does not make a timely election to convert all or a portion of a LIBOR Advance into a new LIBOR Advance in accordance with Section 2.1(a)(i)(B)(2) such LIBOR Advance shall be automatically converted to a Base Rate Advance upon expiration of the Interest Period applicable to such LIBOR Advance.

               (5) Notwithstanding the foregoing or any other provision hereof to the contrary, in addition to the number of Advances permissible monthly under the Commitment pursuant to subsection (1) above, Borrower shall be permitted to borrow under the Swing Line multiple times during any calendar month, provided that (A) the Notice of Borrowing with respect to any Swing Line Advance shall be given by Borrower to Administrative Agent no later than 11:00 A.M. (San Francisco time) on the proposed Funding Date of such Swing Line Advance and shall designate such Advance as a Swing Line Advance; and (B) each requested Advance under the Swing Line shall equal Two Hundred Fifty Thousand Dollars ($250,000) or an integral multiple of Ten Thousand Dollars ($10,000) in excess thereof. The obligation of Administrative Agent (as the Swing Line Lender) to fund Swing Line Advances in accordance with Section 2.1(a)(iii) below shall not be subject to Section 10.3(a) or (b). The other Lenders have no obligation under Section 10.3(c) to fund their Pro Rata Share of any Swing Line Advance (but do have an obligation to fund an Advance to replace such Swing Line Advance in accordance with such Section 10.3(a)), and the Administrative Agent alone (as the Swing Line Lender) shall fund all Swing Line Advances. Except as provided in Section 2.1(a)(iii) below, in the preceding sentences of this Section 2.1(a)(i)(B)(5), in Section 2.6(a) or in Section 10.3, all other provisions of this Agreement shall apply to any such Swing Line Advance.

               (ii) Bid Facility.

          (A) Bid Advances. Each Lender severally agrees that,

               (1) subject to the conditions that at the time of Borrower’s submission of the relevant Competitive Bid Request, (a) Borrower’s Long Term Unsecured Senior Debt Rating is equal to or higher than BBB-/Baa3 and (b) no Event of Default or Unmatured Event of Default has occurred and is continuing, Borrower may, in accordance with this Section 2.1(a)(ii) and the other relevant provisions of the Loan Documents, from time to time request that the Lenders, at any time before the 32nd day prior to the Maturity Date, submit Competitive Bids to make Bid Advances to Borrower; provided, however, that (A) at no time shall the aggregate principal amount of all outstanding Bid Advances cause the aggregate principal amount of all outstanding Advances (taking into account any repayments of Advances with the proceeds thereof) to exceed the applicable dollar limitations of Sections 2.1(a)(i) above; (B) at no time shall the aggregate outstanding principal amount of all Bid Advances (taking into account any repayments of Advances with the proceeds thereof) exceed the Bid Advance Limit; (3) at no time may the number of Fixed Rate Periods of then outstanding Fixed Rate Bid Advances and Absolute Rate Bid Advances exceed eight, in each case giving effect to any Bid Advances then requested; and (C) Borrower shall not issue a Competitive Bid Request for a Bid Advance having a term of other than 30, 60 or 90 days or a maturity date subsequent to the Maturity Date.

               (2) The Lenders may, but shall not be obligated to, submit Competitive Bids in response to any Competitive Bid Request, and Borrower may, but shall not be obligated to, accept any such offers. Subject to other provisions of this Section 2.1, the obligation of a Lender to fund its Pro Rata Share of Advances shall be unaffected by its making of any Bid Advances, even if such Lender makes Bid Advances in an aggregate amount in excess of its Pro Rata Share of the Commitment.

               (3) On the last day of each Fixed Rate Period applicable to any Bid Advances, Borrower shall pay to Administrative Agent, for the respective accounts of the Lenders making such Bid Advances, the full amount of the principal of such Bid Advances. Borrower shall not prepay all or any portion of the principal balance of any Bid Advance (i.e., make any payment of principal on any Bid Advance prior to the end of the Fixed Rate Period applicable to such Bid Advance) without the prior written consent of the Lender which made such Bid Advance (which consent may be withheld in the sole and absolute discretion of such Lender).

          (B) Type of Bid Advances. Bid Advances made under this Section 2.1(a)(ii) may be Absolute Rate Bid Advances or Fixed Rate Bid Advances, subject, however, to Section 2.4(j).

          (C) Bid Advance Borrowings.

               (1) When Borrower desires to effect one or more borrowings consisting of one or more Bid Advances, but not more often than once in any period of thirty (30) consecutive days, Borrower shall notify Administrative Agent by telephone (followed

Page 35

promptly by a facsimile of the related Competitive Bid Request) no later than 8:00 A.M. (California time), (x) in the case of a Fixed Rate Auction, five Business Days prior to the proposed Funding Date of the requested borrowings, or (y) in the case of an Absolute Rate Auction, two Business Days prior to the proposed Funding Date of the requested borrowing(s), in each case, together with a fee payable to Administrative Agent as provided in a separate agreement between Administrative Agent and Borrower, specifying (together with the other information required to be provided pursuant to the Competitive Bid Request):

               (a) the Funding Date of such borrowing(s), which shall be a Business Day;

               (b) the aggregate amount of such borrowing(s), which, subject to the following proviso, shall be in a minimum amount (subject to the limitations set forth in other provisions of the Loan Documents) of $15,000,000 and in integral multiples of $1,000,000 in excess thereof, provided that the aggregate amount of all Fixed Rate Bid Advances with the same Fixed Rate Period shall be in a minimum amount of $15,000,000 and integral multiples of $1,000,000 in excess thereof;

               (c) whether the requested borrowing(s) is/are to be made as either (1) one or more Fixed Rate Bid Advances or (2) one or more Absolute Rate Bid Advances; and

               (d) the duration of the requested Fixed Rate Period (subject to the limitation that Borrower may request no more than three Fixed Rate Periods in any single Competitive Bid Request).

Borrower’s right to request Competitive Bids for Bid Advances, and each Lender’s obligation to fund any Bid Advance pursuant to any Competitive Bid accepted by Borrower, and all Bid Advances made from time to time, shall be subject in all respects to the provisions of Section 2.4(j).

               (2) On the same day that it receives a Competitive Bid Request, Administrative Agent shall send a copy thereof to each of the Lenders by facsimile, attaching thereto notice of the date and time (as specified in Section 2.1(a)(ii)(C)(3) below) by which responses must be received in order to be considered by Borrower. The Competitive Bid Request shall not constitute an offer by Borrower, but merely an invitation to the Lenders to submit Competitive Bids with respect to the requested borrowing(s).

               (3) (A) Each Lender may, in its sole and absolute discretion, submit a Competitive Bid, substantially in the form attached hereto as Exhibit B-3, containing an offer or offers to make Bid Advances in response to any Competitive Bid Request. Each Competitive Bid must comply with the provisions of this Section 2.1(a)(ii)(C)(3) and must be submitted to Administrative Agent (or, in the case of a Competitive Bid being submitted by Administrative Agent in its capacity as a Lender, to Borrower), by

Page 36

facsimile, no later than 7:00 A.M. (or, in the case of a Competitive Bid by Administrative Agent, in its capacity as Lender, 6:30 A.M.), California time, (1) in the case of a Fixed Rate Auction, three Business Days prior to the Funding Date of the proposed Borrowing(s), or (2) in the case of an Absolute Rate Auction, on the Funding Date. Each Competitive Bid so submitted (subject only to the provisions of Section 2.1(a)(ii)(A)(1) above and to the satisfaction of all other conditions precedent to the requested Bid Advance(s)) shall be irrevocable, unless Borrower otherwise agrees in writing.

                    (B) Each Competitive Bid shall identify and be signed on behalf of the submitting Lender, shall specify the date of the proposed borrowing(s) specified in the Competitive Bid Request to which the submitting Lender is responding and shall specify:

               (1) the principal amount of each Bid Advance for which a Competitive Bid is being made (which shall not be limited by the submitting Lender’s Pro Rata Share of the Commitment, but which shall be in an amount, no greater than the amount of the requested borrowing, equal to $5,000,000 or an integral multiple of $1,000,000 in excess thereof); and

               (2) (aa) in the case of a Fixed Rate Auction, the LIBOR Bid Margin offered by the submitting Lender, or (bb) in the case of an Absolute Rate Auction, the Absolute Rate offered by the submitting Lender.

A Competitive Bid may include up to three separate offers by the submitting Lender with respect to each Fixed Rate Period specified in the Competitive Bid Request to which it responds. Any Competitive Bid that (X) does not include all the information required by this Section, (Y) contains language that qualifies or conditions the submitting Lender’s offer to make the Bid Advance(s) described therein or to otherwise make such an offer revocable or proposes terms other than (or in addition to) the terms proposed in the relevant Competitive Bid Request other than by setting an aggregate limit on the principal amount of Bid Advances for which offers being made by the submitting Lender may be accepted, or (Z) is received by Administrative Agent (or Borrower, as applicable) after the time set forth in this Section (unless amended to bring it into compliance with respect to any noncompliance described in clause (X) or (Y), in either case prior to the time set forth in this Section) shall be disregarded.

               (4) Promptly upon receipt, but not later than 8:00 A.M. (California time) on the date by which Competitive Bids are required to have been submitted with respect to a Competitive Bid Request, Administrative Agent shall notify Borrower of (i)(A) the terms of each Competitive Bid (other than one that is to be disregarded as described above) received in response to the Competitive Bid Request, and (B) the identity of the Lender submitting such Competitive Bid, and (ii)(A) the aggregate principal amount of Bid Advances for which Competitive Bids have been received for each Fixed Rate Period requested in the Competitive Bid Request, and (B) the respective principal amounts and LIBOR Bid Margins or Absolute Rates, as the case may be, so offered.

Page 37

               (5) No later than 8:30 A.M. (California time) on the date by which Competitive Bids are required to have been submitted with respect to a Competitive Bid Request, Borrower shall notify Administrative Agent, by means of a notice reasonably acceptable to Administrative Agent in form, of its acceptance or rejection of the offers notified to it as provided in Section 2.1(a)(ii)(C)(4) above. Borrower shall have no obligation to accept any such offer, and may choose to reject all of them. If Borrower has failed to timely notify Administrative Agent of its acceptance or rejection of any one or more offers by the time specified in this Section, Borrower shall be deemed to have rejected such offer(s). Borrower may accept any Competitive Bid (other than one that is to be disregarded as provided above) in whole or in part, provided that:

               (a) the aggregate principal amount of the Competitive Bids so accepted may not exceed the aggregate amount of the borrowing(s) requested in the relevant Competitive Bid Request;

               (b) (i) subject to the provisions set forth below with respect to multiple offers at the same LIBOR Bid Margin or Absolute Rate, the principal amount of each accepted Competitive Bid must be in an amount equal to $5,000,000 or an integral multiple of $1,000,000 in excess thereof and (ii) Competitive Bids must be accepted with respect to an aggregate principal amount of at least $15,000,000 or an integral multiple of $1,000,000 in excess thereof; and

               (c) with respect to each Fixed Rate Period for which Competitive Bids were requested, Borrower shall accept offers solely on the basis of ascending LIBOR Bid Margins or Absolute Rates, as the case may be (provided that Borrower may, to the extent necessary to comply with the preceding subparagraph (b), accept only part of an offer at a particular LIBOR Bid Margin or Absolute Rate and accept all or part of one or more offers at a higher LIBOR Bid Margin or Absolute Rate).

If Borrower chooses to accept one or more offers, Borrower shall deliver a notice to Administrative Agent by not later than 8:30 A.M. (California time), in such form as Administrative Agent may from time to time reasonable request), specifying the aggregate principal amount of offers with respect to each requested Fixed Rate Period that it chooses to accept. If two or more Lenders offer the same LIBOR Bid Margin or Absolute Rate for an aggregate principal amount greater than the amount for which such offers were requested (or greater than the remaining portion of such offers that has not been allocated to offers at lower Fixed Rate Bid Margins or Absolute Rates) with respect to any requested Fixed Rate Period, Borrower shall allocate the principal amount of the affected Bid Advances among such Lenders as nearly as possible (in such multiples, not less than $1,000,000, as Borrower may deem appropriate) in proportion to the aggregate principal amounts to which their respective offers related. Borrower’s allocation, in the absence of manifest error, shall be conclusive.

               (6) Promptly upon receipt of the notice from Borrower pursuant to Section 2.1(a)(ii)(C)(5) above, Administrative Agent shall promptly notify each Lender having submitted a Competitive Bid whether its offer has been accepted and, if its offer

Page 38

has been accepted, of the amount of the Bid Advance(s) to be made by it on the date of the relevant borrowing(s).

               (7) Promptly (but no later than one Business Day) following each borrowing of one or more Bid Advances, Administrative Agent shall notify each Lender (whether or not such Lender submitted a Competitive Bid with respect to such borrowing) of the ranges of Competitive Bids submitted and the highest and lowest Competitive Bids accepted for each Fixed Rate Period requested by Borrower and of the aggregate amount of the Bid Advances made pursuant to such Borrowing.

               (8) Upon receipt of a Competitive Bid Request in proper form requesting Competitive Bids to make a Bid Advance that is a Fixed Rate Advance under Section 2.1(a)(ii)(C)(1) above, Administrative Agent shall determine the LIBOR Rate applicable to each of the Fixed Rate Periods specified in the Competitive Bid Request, and shall, two Business Days prior to the beginning of such Fixed Rate Period, send a written notice specifying such rate (or rates, as the case may be) to Borrower and the Lenders; provided, however, that failure to give such notice to any Person shall not affect the validity of such rate.

               (9) Not later than 10:00 A.M. (California time) on the date specified in such notice as the Funding Date, each Lender that submitted a Competitive Bid that was accepted by Borrower, subject to the terms and conditions hereof, shall make its Bid Advance available, in immediately available funds, to Administrative Agent.

          (D) Funding of Bid Advances. Subject to and upon satisfaction of the applicable conditions set forth in Article 3, as determined by Administrative Agent, Administrative Agent shall make the proceeds of the requested Bid Advances available to Borrower in Dollars in immediately available funds in Borrower’s deposit account referred to in Section 2.1(b).

                    (iii) Swing Line Advances.

          (A) There is hereby established a sub-facility (the “Swing Line”), in the amount of Twenty Million Dollars ($20,000,000), under and as a part of the Commitment. The Swing Line shall not for any purpose be an addition to the Commitment, but shall be a sub-feature thereunder. All Advances requested to be made pursuant to the Swing Line shall be subject to the same terms and conditions applicable to other Advances under the Commitment, and all outstanding Swing Line Advances shall likewise be subject to the same terms and conditions applicable to other outstanding Advances under the Commitment, except as expressly provided in (1) the following Section 2.1(a)(iii)(B), (2) Section 2.1(a)(i)(B)(5) with respect to the number of Borrowings permitted in any calendar month, the time within which the Notice of Borrowing for Swing Line Advances must be given, the minimum and incremental amounts applicable to Swing Line Advances and the interest rate applicable thereto, (3) Section 2.6(a) with respect to prepayments of Swing Line Advances, and (4) Section 10.3(c).

          (B) The Swing Line Lender hereby agrees to make Advances to Borrower from time to time during the period from the Closing Date to the date seven (7) Business Days prior to the Maturity Date, in an aggregate principal amount not exceeding at any one time the lesser of

Page 39

(1) the Loan Availability less the outstanding principal of all Advances other than Swing Line Advances, and (2) Twenty Million Dollars ($20,000,000). The Swing Line Lender’s obligation to fund Swing Line Advances shall be unaffected by its making of any other Loans, notwithstanding that the sum of the Swing Line Advances plus the Swing Line Lender’s Pro Rata Share of the aggregate principal amount of the outstanding Commitment other than Swing Line Advances may exceed the Swing Line Lender’s Commitment.

          (C) Any Swing Line Advance which is not repaid (either by Borrower funds or by a Borrower requested Advance under the Loan) within five (5) Business Days after such Swing Line Advance’s date of funding shall, in accordance with the provisions of Section 10.3(c) hereof and for purposes of determining availability of Swing Line Advances, be converted to an Advance under the Loan (and no longer considered a Swing Line Advance), which Advance shall accrue interest at the Base Rate.

               (iv) Letters of Credit.

          (A) Letters of Credit. Subject to the terms and conditions of this Agreement, the Administrative Agent, on behalf of the Lenders, agrees to issue for the account of the Borrower during the period from and including the Closing Date to, but excluding, the L/C Maturity Date one or more standby letters of credit (each a “Letter of Credit”) up to a maximum aggregate Stated Amount at any one time outstanding not to exceed the L/C Commitment Amount.

          (B) Terms of Letters of Credit. At the time of issuance, the amount, form, terms and conditions of each Letter of Credit shall be subject to approval by the Administrative Agent and the Borrower. All Letters of Credit shall be issued in United States Dollars. Notwithstanding the foregoing, in no event may (i) the expiration date of any Letter of Credit extend beyond the L/C Maturity Date, (ii) any Letter of Credit have an initial duration in excess of one year, or (iii) any Letter of Credit contain an automatic renewal provision which (x) would allow such Letter of Credit to be renewed more often than annually or (y) would allow, after giving effect to all renewal periods, the expiration date of such Letter of Credit to extend beyond the L/C Maturity Date. The initial Stated Amount of each Letter of Credit shall be at least $1,000,000.

          (C) Requests for Issuance of Letters of Credit. The Borrower shall give the Administrative Agent written notice at least five (5) Business Days prior to the requested date of issuance of a Letter of Credit, such notice to describe in reasonable detail the proposed terms of such Letter of Credit and the nature of the transactions or obligations proposed to be supported by such Letter of Credit, and in any event shall set forth with respect to such Letter of Credit (i) the proposed initial Stated Amount, (ii) the beneficiary, and (iii) the expiration date. The Borrower shall also execute and deliver such customary applications and agreements for standby letters of credit, and other forms as requested from time to time by the Administrative Agent. Provided the Borrower has timely given the notice prescribed by the first sentence of this subsection and delivered such application and agreements referred to in the preceding sentence, and provided that Administrative Agent and the proposed beneficiary of the requested Letter of Credit have agreed upon the form of such Letter of Credit, subject to the other terms and conditions of this Agreement, including the satisfaction of any applicable conditions precedent set forth in Article 3, the Administrative Agent shall issue the requested Letter of Credit on the

Page 40

requested date of issuance for the benefit of the stipulated beneficiary but in no event prior to the date five (5) Business Days following the date after which the Administrative Agent has received all of the items required to be delivered to it under this subsection. Upon the written request of the Borrower, the Administrative Agent shall deliver to the Borrower a copy of (x) any Letter of Credit proposed to be issued hereunder prior to the issuance thereof and (y) each issued Letter of Credit within a reasonable time after the date of issuance thereof. To the extent any term of a Letter of Credit Document is inconsistent with a term of any Loan Document, the term of such Loan Document shall control. In no event shall Borrower request that a Letter of Credit be issued on a date that is less than thirty (30) days prior to the Maturity Date.

          (D) Reimbursement Obligations. Upon receipt by the Administrative Agent from the beneficiary of a Letter of Credit of any demand for payment under such Letter of Credit, the Administrative Agent shall promptly notify the Borrower of the amount to be paid by the Administrative Agent as a result of such demand and the date on which payment is to be made by the Administrative Agent to such beneficiary in respect of such demand. The Borrower hereby absolutely, unconditionally and irrevocably agrees to pay and reimburse the Administrative Agent for the amount of each demand for payment under such Letter of Credit at or prior to the date on which payment is to be made by the Administrative Agent to the beneficiary thereunder, without presentment, demand, protest or other formalities of any kind. Upon receipt by the Administrative Agent of any payment in respect of any Reimbursement Obligation, the Administrative Agent shall, to the extent such amount was previously funded by the Lenders, promptly pay to each Lender such Lender’s Pro Rata Share of such payment.

          (E) Manner of Reimbursement. Upon its receipt of a notice referred to in the immediately preceding subsection (D), the Borrower shall advise the Administrative Agent whether or not the Borrower intends to borrow hereunder to finance its obligation to reimburse the Administrative Agent for the amount of the related demand for payment and, if it does, the Borrower shall submit a timely Notice of Borrowing as provided in Section 2.1(a)(i)(B). If the Borrower fails to so advise the Administrative Agent, or if the Borrower fails to reimburse the Administrative Agent for a demand for payment under a Letter of Credit by the date of such payment, then (i) if the applicable conditions contained in Article 3 have been satisfied, the Borrower shall be deemed to have requested an Advance (which shall be a Base Rate Advance) in an amount equal to the unpaid Reimbursement Obligation and the Administrative Agent shall give each Lender prompt notice of the amount of the Advance to be made available to the Administrative Agent not later than 11:00 A.M. (California time) and (ii) if the conditions to Article III have not been satisfied, the provisions of subsection (J) of this Section shall apply.

          (F) Effect of Letters of Credit on Commitments. Upon the issuance by the Administrative Agent of any Letter of Credit and until such Letter of Credit shall have expired or been terminated, the Commitment of each Lender shall be deemed to be utilized for all purposes of this Agreement in an amount equal to the product of (i) such Lender’s Pro Rata Share and (ii) the sum of (A) the Stated Amount of such Letter of Credit plus (B) any related Reimbursement Obligations then outstanding.

          (G) Administrative Agent’s Duties Regarding Letters of Credit; Unconditional Nature of Reimbursement Obligation. In examining documents presented in connection with drawings under Letters of Credit and making payments under such Letters of Credit against such

Page 41

documents, the Administrative Agent shall only be required to use the same standard of care as it uses in connection with examining documents presented in connection with drawings under letters of credit in which it has not sold participations and making payments under such letters of credit. The Borrower assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing, neither the Administrative Agent nor any of the Lenders shall be responsible for (i) the form, validity, sufficiency, accuracy, genuineness or legal effects of any document submitted by any party in connection with the application for and issuance of or any drawing honored under any Letter of Credit even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit, or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) failure of the beneficiary of any Letter of Credit to comply fully with conditions required in order to draw upon such Letter of Credit; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telex, telecopy or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any Letter of Credit, or of the proceeds thereof; (vii) the misapplication by the beneficiary of any Letter of Credit, or of the proceeds of any drawing under any Letter of Credit; or (viii) any consequences arising from causes beyond the control of the Administrative Agent or the Lenders. None of the above shall affect, impair or prevent the vesting of any of the Administrative Agent’s rights or powers hereunder. Any action taken or omitted to be taken by the Administrative Agent under or in connection with any Letter of Credit, if taken or omitted in the absence of gross negligence or willful misconduct, shall not create against the Administrative Agent any liability to the Borrower or any Lender. In this connection, the obligation of the Borrower to reimburse the Administrative Agent for any drawing made under any Letter of Credit shall be absolute, unconditional and irrevocable and shall be paid strictly in accordance with the terms of this Agreement or any other applicable Letter of Credit Document under all circumstances whatsoever, including without limitation, the following circumstances: (A) any lack of validity or enforceability of any Letter of Credit Document or any term or provisions therein; (B) any amendment or waiver of or any consent to departure from all or any of the Letter of Credit Documents; (C) the existence of any claim, setoff, defense or other right which the Borrower may have at any time against the Administrative Agent, any Lender, any beneficiary of a Letter of Credit or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or in the Letter of Credit Documents or any unrelated transaction; (D) any breach of contract or dispute between the Borrower, the Administrative Agent, any Lender or any other Person; (E) any demand, statement or any other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein or made in connection therewith being untrue or inaccurate in any respect whatsoever; (F) any non-application or misapplication by the beneficiary of a Letter of Credit or of the proceeds of any drawing under such Letter of Credit; (G) payment by the Administrative Agent under the Letter of Credit against presentation of a draft or certificate which does not strictly comply with the terms of the Letter of Credit; and (H) any other act, omission to act, delay or circumstance whatsoever that might, but for the provisions of this Section, constitute a legal or equitable defense to or discharge of the Borrower’s Reimbursement Obligations.

Page 42

          (H) Amendments, Etc. The issuance by the Administrative Agent of any amendment, supplement or other modification to any Letter of Credit shall be subject to the same conditions applicable under this Agreement to the issuance of new Letters of Credit (including, without limitation, that the request therefor be made through the Administrative Agent), and no such amendment, supplement or other modification shall be issued unless either (i) the respective Letter of Credit affected thereby would have complied with such conditions had it originally been issued hereunder in such amended, supplemented or modified form or (ii) the Requisite Lenders shall have consented thereto. In connection with any such amendment, supplement or other modification, the Borrower shall pay the fees, if any, payable under the last sentence of Section 2.5(e).

          (I) Lenders’ Participation in Letters of Credit. Immediately upon the issuance by the Administrative Agent of any Letter of Credit each Lender shall be deemed to have absolutely, irrevocably and unconditionally purchased and received from the Administrative Agent, without recourse or warranty, an undivided interest and participation to the extent of such Lender’s Pro Rata Share of the liability of the Administrative Agent with respect to such Letter of Credit and each Lender thereby shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and shall be unconditionally obligated to the Administrative Agent to pay and discharge when due, such Lender’s Pro Rata Share of the Administrative Agent’s liability under such Letter of Credit. In addition, upon the making of each payment by a Lender to the Administrative Agent in respect of any Letter of Credit pursuant to the immediately following subsection (J), such Lender shall, automatically and without any further action on the part of the Administrative Agent or such Lender, acquire (i) a participation in an amount equal to such payment in the Reimbursement Obligation owing to the Administrative Agent by the Borrower in respect of such Letter of Credit and (ii) a participation in a percentage equal to such Lender’s Pro Rata Share in any interest or other amounts payable by the Borrower in respect of such Reimbursement Obligation (other than the fees payable to the Administrative Agent pursuant to the last sentence of Section 2.5(e)).

          (J) Payment Obligation of Lenders. Each Lender severally agrees to pay to the Administrative Agent on demand in immediately available funds the amount of such Lender’s Pro Rata Share of each drawing paid by the Administrative Agent under each Letter of Credit to the extent such amount is not reimbursed by the Borrower pursuant to Subsection (D) above of this Section. Each such Lender’s obligation to make such payments to the Administrative Agent under this subsection, and the Administrative Agent’s right to receive the same, shall be absolute, irrevocable and unconditional and shall not be affected in any way by any circumstance whatsoever, including without limitation, (i) the failure of any other Lender to make its payment under this subsection, (ii) the financial condition of the Borrower, the REIT, or any other Consolidated Entity, (iii) the existence of any Unmatured Event of Default or Event of Default, including any Event of Default described in Section 9.1(g) or Section 9.1(h), or (iv) the termination of the Commitments. Each such payment to the Administrative Agent shall be made without any offset, abatement, withholding or deduction whatsoever.

          (K) Information to Lenders. Promptly following any change in the Stated Amount of Letters of Credit outstanding, the Administrative Agent shall deliver to each Lender and the Borrower a notice describing the aggregate amount of all Letters of Credit outstanding at such time. Upon the request of any Lender from time to time, the Administrative Agent shall deliver

Page 43

any other information reasonably requested by such Lender with respect to each Letter of Credit then outstanding. Other than as set forth in this subsection, the Administrative Agent shall have no duty to notify the Lenders regarding the issuance or other matters regarding Letters of Credit issued hereunder. The failure of the Administrative Agent to perform its requirements under this subsection shall not relieve any Lender from its obligations under Subsection (J) of this Section.

          (b) Making of Advances. Subject to Section 10.3 or as otherwise provided herein, Administrative Agent shall deposit the proceeds of each new Advance in Borrower’s account number 001-223275 at the Beverly Hills Office of City National Bank, in accordance with a separate, fully executed “Funds Transfer Agreement” on Administrative Agent’s standard form.

          (c) Term. The outstanding balance of the Advances shall be payable in full on the earliest to occur of, (i) April 30, 2009 (as such date may be extended pursuant to Section 2.1(d), (ii) the acceleration of the Advances pursuant to Section 9.2(a), or (iii) Borrower’s written notice to Administrative Agent (pursuant to Section 2.8) of Borrower’s election to prepay all accrued Obligations and terminate the Commitment (said earliest date referred to herein as the “Maturity Date”).

          (d) Extension of the Maturity Date. No less than ninety (90) days prior to the Maturity Date, Borrower may elect to extend the Maturity Date for one (1) year by delivering written notice of such election to Administrative Agent. Within five (5) Business Days after Administrative Agent’s receipt of such written election, Administrative Agent shall deliver a copy of such written election to each Lender. Such extension shall become effective only if (i) both at the time of such written election, and as of the original Maturity Date, no Event of Default or Unmatured Event of Default has occurred and is continuing, and (ii) Borrower pays the extension fee required by Section 2.5(d). If such requested extension becomes effective in accordance with the preceding sentence, the original Maturity Date shall be extended to April 30, 2010. In all other cases, the original Maturity Date shall not be extended. Administrative Agent may, in its discretion, increase the Capitalization Rate applicable during the extension term from eight and one-quarter percent (8.25%) to eight and one-half percent (8.50%) if such increase is made by Administrative Agent in good faith and on a basis consistent with capitalization rates that Administrative Agent is then generally applying to Office Properties in the relevant markets; provided, however, that no such increase in the Capitalization Rate during the extension term shall become effective unless the Administrative Agent notifies the Borrower of such increase not later than thirty (30) days following a written request therefor by Borrower, which request may be made by Borrower within one hundred fifty (150) days prior to, but not later than forty-five (45) days prior to, the original Maturity Date.

          (e) Prior Loan.

          (i) Effective as of the Closing Date, all Indebtedness and Obligations of Borrower relating to the Prior Loan and arising under the Prior Credit Agreement, the Prior Notes and any other Prior Loan Documents are hereby amended and restated in full by this Agreement, the Notes and the Loan Documents. On the Closing Date, the Prior Notes shall be canceled and promptly thereafter returned to Borrower. In the event that any Lender does not return its note or notes within twenty (20) days after the Closing

Page 44

Date, Borrower shall be entitled to receive a lost note affidavit in customary form from the Lender, including an indemnity agreement reasonably satisfactory to Borrower, with respect to the unreturned note or notes. Without limiting the generality of the foregoing, effective as of the Closing Date, the commitment of the Prior Lenders to make additional Advances under (and as defined in) the Prior Credit Agreement shall automatically terminate, and Borrower acknowledges and agrees that, effective as of the Closing Date, no Prior Lender (or any Lender) shall have any further obligations to Borrower under the Prior Credit Agreement, the Prior Notes or any other Prior Loan Document.

(ii) Effective as of July ___, 2005, certain of the Lenders shall purchase, and certain of the Lenders shall sell, to one another, the percentage interest in the Commitment as reflected in Schedule 2.1(e) hereto, in order to reallocate the Carryover Principal Balance under the Notes among the Lenders to correspond to the Pro Rata Shares of the Lenders specified in Schedule 1.1 hereto. The applicable purchase price payments are specified in Schedule 2.1(e) hereto and are referred to herein as the “Adjusting Purchase Payments”. The Adjusting Purchase Payments shall be made to Administrative Agent by the applicable purchasing Lender by Federal Reserve wire transfer initiated by the payor no later than 8:00 A.M. (California time) on July ___, 2005. Upon receipt of all such payments, Administrative Agent shall promptly send appropriate portions thereof to the selling Lenders by Federal Reserve wire transfer. The parties to this Agreement acknowledge that the Adjusting Purchase Payments do not include interest or fees, which Borrower is obligated pursuant to the terms of Section 3.1(i) to pay through and including July ___, 2005.

     2.2. Authorization to Obtain Advances. Schedule 2.2 sets forth the names of those employees of Borrower authorized by Borrower to sign Notices of Borrowing and requests for Letters of Credit, and Administrative Agent and Lenders shall be entitled to rely on such Schedule until notified in writing by Borrower of any change(s) of the persons so authorized. Administrative Agent shall be entitled to act on the instructions of anyone identifying himself or herself as one of the Persons authorized to execute a Notice of Borrowing, and Borrower shall be bound thereby in the same manner as if such Person were actually so authorized. Borrower agrees to indemnify, defend and hold Lenders and Administrative Agent harmless from and against any and all Liabilities and Costs which may arise or be created by the acceptance of instructions in any Notice of Borrowing, unless caused by the gross negligence or willful misconduct of the Person to be indemnified.

     2.3. Lenders’ Accounting. Administrative Agent shall maintain a loan account (the “Loan Account”) on its books in which shall be recorded (a) the names and addresses and the Pro Rata Shares of the Commitment of each of the Lenders, and the principal amount of Advances owing to each Lender from time to time, and (b) all Advances and repayments of principal and payments of accrued interest, as well as payments of fees required to be paid pursuant to this Agreement, and prepayments under the Swing Line. All entries in the Loan Account shall be made in accordance with Administrative Agent’s customary accounting practices as in effect from time to time. Monthly or at such other interval as is customary with Administrative Agent’s practice, Administrative Agent will render a statement of the Loan Account to Borrower and will deliver a copy thereof to each Lender. Each such statement shall be deemed final,

Page 45

binding and conclusive upon Borrower in all respects as to all matters reflected therein (absent manifest error).

     2.4. Interest on the Advances.

          (a) Base Rate Advances; Swing Line Advances. Subject to Section 2.4(f), all Base Rate Advances shall bear interest on the daily unpaid principal amount thereof from the date made until paid in full at a fluctuating rate per annum equal to the Base Rate. Base Rate Advances shall be made in minimum amounts of Two Hundred Fifty Thousand Dollars ($250,000). All Swing Line Advances shall bear interest on the daily unpaid principal amount thereof from the date made until paid in full at a rate per annum equal to the Base Rate in effect during such time period less the Applicable Swing Line Advance Margin.

          (b) LIBOR Advances. Subject to Sections 2.4(f) and 2.4(j), LIBOR Advances shall bear interest on the unpaid principal amount thereof during the Interest Period applicable thereto at a rate per annum equal to the sum of the LIBOR Rate for such Interest Period plus the Applicable LIBOR Rate Margin. LIBOR Advances shall be in amounts of One Million Dollars ($1,000,000) or Fifty Thousand Dollars ($50,000) increments in excess thereof. No more than eight (8) LIBOR Advances shall be outstanding at any one time. Notwithstanding anything to the contrary contained herein and subject to the default interest provisions contained in Section 2.4(f), if an Event of Default occurs and as a result thereof the Commitment is terminated and the Loan thereby accelerated, then all LIBOR Advances shall be converted to Base Rate Advances upon the date of such acceleration, and Borrower shall pay Lenders any Fixed Rate Price Adjustment in connection therewith.

          (c) Absolute Rate Bid Advances. Subject to Section 2.4(f) and Section 2.4(j), all Absolute Rate Bid Advances shall bear interest on the unpaid principal amount thereof during the Fixed Rate Period applicable thereto at a fixed rate per annum equal to the Absolute Rate quoted by the Lender making such Bid Advance pursuant to Section 2.1(a)(ii)(C)(3) and accepted by Borrower pursuant to Section 2.1(a)(ii)(C)(5).

          (d) Fixed Rate Bid Advances. Subject to Sections 2.4(f) and 2.4(j), Fixed Rate Bid Advances shall bear interest on the unpaid principal amount thereof during the Fixed Rate Period applicable thereto at a fixed rate per annum equal to the LIBOR Rate plus or minus the LIBOR Bid Margin quoted by the Lender making such Bid Advance pursuant to Section 2.1(a)(ii)(C)(3) and accepted by Borrower pursuant to Section 2.1(a)(ii)(C)(5).

          (e) Interest Payments. Subject to Section 2.4(f), interest accrued on all Advances (other than Advances in respect of which interest is determined on the basis of LIBOR) shall be payable by Borrower, in the manner provided in Section 2.6(b) in arrears on the first Business Day of the first calendar month following the Closing Date, the first Business Day of each succeeding calendar month thereafter, and on the Maturity Date. Interest on LIBOR based Advances shall be payable in the manner provided in Section 2.6(b) in arrears at the end of the Interest Period applicable to such Advance, but in no event less frequently than once every three months with respect to each Interest Period.

Page 46

          (f) Default Interest. Notwithstanding the rates of interest specified in Sections 2.4(a) and 2.4(b) and the payment dates specified in Section 2.4(e), effective at the option of Requisite Lenders following the occurrence and during the continuance of any Event of Default, the principal balance of all Advances then outstanding and, to the extent permitted by applicable law, any interest payments not paid when due, shall bear interest, payable upon demand, at a rate which is three percent (3%) per annum in excess of the rate(s) of interest otherwise payable from time to time under this Agreement. Notwithstanding anything to the contrary in any of the other Loan Documents, all other amounts due Administrative Agent or the Lenders (whether directly or for reimbursement) under this Agreement or any of the other Loan Documents if not paid when due, or if no time period is expressed, if not paid within ten (10) days after written demand, shall bear interest from and after demand at the rate set forth in this Section 2.4(f).

          (g) Intentionally Omitted.

          (h) Computation of Interest. Interest shall be computed on the basis of the actual number of days elapsed in the period during which interest or fees accrue and a year of three hundred sixty (360) days, except that interest on Base Rate Advances shall be calculated on the basis of the actual number of days in the applicable calendar year (i.e., 365 or 366, as applicable). In computing interest on any Advance, subject to Section 2.6(b), the date of the making of the Advance shall be included and the date of payment shall be excluded; provided, however, that if an Advance is repaid on the same day on which it is made, one (1) day’s interest shall be paid on that Advance. Notwithstanding any provision in this Section 2.4, interest in respect of any Advance shall not exceed the maximum rate permitted by applicable law.

          (i) Changes; Legal Restrictions. In the event that, after the Closing Date, (A) the adoption of or any change in any law, treaty, rule, regulation, guideline or determination of a court or Governmental Authority or any change in the interpretation or application thereof by a court or Governmental Authority, or (B) compliance by Administrative Agent or any Lender with any request or directive made or issued after the Closing Date (whether or not having the force of law and whether or not the failure to comply therewith would be unlawful) from any central bank or other Governmental Authority or quasi-governmental authority:

          (i) subjects Administrative Agent or any Lender to any tax, duty or other charge of any kind with respect to the Commitment, this Agreement or any of the other Loan Documents, including the Notes or the Advances, or changes the basis of taxation of payments to Administrative Agent or such Lender of principal, fees, interest or any other amount payable hereunder, except for net income, gross receipts, gross profits or franchise taxes imposed by any jurisdiction and not specifically based upon loan transactions (all such non-excepted taxes, duties and other charges being hereinafter referred to as “Lender Taxes”);

          (ii) imposes, modifies or holds applicable, in the determination of Administrative Agent or any Lender, any reserve, special deposit, compulsory loan, FDIC insurance, capital allocation or similar requirement against assets held by, or deposits or other liabilities in or for the account of, advances or loans by, or other credit extended by, or any other acquisition of funds by, Administrative Agent or such Lender

Page 47

or any applicable lending office (except to the extent that the reserve and FDIC insurance requirements are reflected in the “Base Rate” or in determining the LIBOR Rate);

          (iii) imposes on Administrative Agent or any Lender any other condition materially more burdensome in nature, extent or consequence than those in existence as of the Closing Date; or

          (iv) imposes, modifies or deems applicable any tax, reserve, special deposit, capital adequacy or similar requirement against or with respect to or measured by reference to Letters of Credit, then, upon demand by the Administrative Agent or such Lender,

and the result of any of the foregoing is to increase the cost to Administrative Agent or any Lender of making, renewing, maintaining or participating in the Advances or to reduce any amount receivable thereunder (or the cost of issuing (or any Lender of purchasing participations in) or maintaining its obligation hereunder to issue (or purchase participations in) any Letter of Credit or reduce any amount receivable by the Administrative Agent or any Lender hereunder in respect of any Letter of Credit); then in any such case, Borrower shall promptly pay to Administrative Agent or such Lender, as applicable, within seven (7) days after Borrower’s receipt of written demand, such amount or amounts (based upon a reasonable allocation to this Agreement and directly related to the change in circumstances set forth in this Section 2.4(i)) as may be necessary to compensate Administrative Agent or such Lender for any such additional cost incurred or reduced amounts received. Administrative Agent or such Lender shall deliver to Borrower and in the case of a delivery by such Lender, such Lender shall also deliver to Administrative Agent, a written statement of the claimed additional costs incurred or reduced amounts received and the basis therefor as soon as reasonably practicable after such Lender obtains knowledge thereof. If Administrative Agent or any Lender subsequently recovers any amount of Lender Taxes previously paid by Borrower pursuant to this Section 2.4(i), whether before or after termination of this Agreement, then, upon receipt of good funds with respect to such recovery, Administrative Agent or such Lender will refund such amount to Borrower if no Event of Default or Unmatured Event of Default then exists or, if an Event of Default or Unmatured Event of Default then exists, such amount will be credited to the Obligations in the manner determined by Administrative Agent or such Lender.

          (j) Certain Provisions Regarding LIBOR Advances, Fixed Rate Bid Advances and Absolute Rate Bid Advances.

          (i) Certain Lending Unlawful. If any Lender shall determine (which determination shall, upon notice thereof to Borrower and Administrative Agent, be conclusive and binding on the parties hereto) that after the Closing Date the introduction of or any change in or in the interpretation of any law makes it unlawful, or any central bank or other Governmental Authority asserts that it is unlawful, for such Lender to make or maintain any Advance as a LIBOR Advance, Fixed Rate Bid Advance or Absolute Rate Bid Advance, (A) the obligations of such Lender to make or maintain any Advances as LIBOR Advances, Fixed Rate Bid Advances or Absolute Rate Bid Advances shall, upon such determination, forthwith be suspended until such Lender shall notify Administrative Agent that the circumstances causing such suspension no longer exist

Page 48

(and such Lender shall give notice if such circumstances no longer exist), and (B) if required by such law or assertion, the existing LIBOR Advances, Fixed Rate Bid Advances or Absolute Rate Bid Advances of such Lender shall automatically convert into Base Rate Advances.

          (ii) Deposits Unavailable. If Administrative Agent shall have determined in good faith that adequate means do not exist for ascertaining the interest rate applicable hereunder to LIBOR Advances, Fixed Rate Bid Advances or Absolute Rate Bid Advances, then, upon notice from Administrative Agent to Borrower the obligations of all the Lenders to make or maintain Advances as LIBOR Advances, Fixed Rate Bid Advances or Absolute Rate Bid Advances shall forthwith be suspended until Administrative Agent shall notify Borrower that the circumstances causing such suspension no longer exist. Administrative Agent will give such notice when it determines, in good faith, that such circumstances no longer exist; provided, however, that neither Administrative Agent nor any Lender shall have any liability to any Person with respect to any delay in giving such notice.

          (iii) Fixed Rate Price Adjustment. Borrower acknowledges that prepayment or acceleration of a LIBOR Advance, Fixed Rate Bid Advance or Absolute Rate Bid Advance during an Interest Period shall result in the Lenders incurring additional costs, expenses and/or liabilities and that it is extremely difficult and impractical to ascertain the extent of such costs, expenses and/or liabilities. (For all purposes of this subparagraph (iii), any Advance not being made as a LIBOR Advance, Fixed Rate Bid Advance or Absolute Rate Bid Advance in accordance with the Notice of Borrowing therefor, as a result of Borrower’s cancellation thereof, shall be treated as if such LIBOR Advance, Fixed Rate Bid Advance or Absolute Rate Bid Advance had been prepaid.) Therefore, on the date a LIBOR Advance, Fixed Rate Bid Advance or Absolute Rate Bid Advance is prepaid or the date all sums payable hereunder become due and payable, by acceleration or otherwise (“Price Adjustment Date”), Borrower shall pay to Administrative Agent, for the account of each Lender (or the applicable Lender in the case of a Fixed Rate Bid Advance or Absolute Rate Bid Advance), in addition to all other sums then owing, an amount (“Fixed Rate Price Adjustment”) equal to the then present value of (A) the amount of interest that would have accrued on the LIBOR Advance, Fixed Rate Bid Advance or Absolute Rate Bid Advance for the remainder of the Interest Period at the rate applicable to such LIBOR Advance, Fixed Rate Bid Advance or Absolute Rate Bid Advance, less (B) the amount of interest that would accrue on the same LIBOR Advance, Fixed Rate Bid Advance or Absolute Rate Bid Advance for the same period if the LIBOR Rate were set on the Price Adjustment Date. The present value shall be calculated by using as a discount rate the LIBOR Rate quoted on the Price Adjustment Date.

By initialing this provision where indicated below, Borrower confirms that Lenders’ agreement to make the Loan at the interest rates and on the other terms set forth herein and in the other Loan Documents constitutes adequate and valuable consideration, given individual weight by Borrower, for this agreement.

BORROWER’S INITIALS: /s/ RSD

Page 49

Within seven (7) days after Borrower’s receipt of written notice from Administrative Agent, Borrower shall immediately pay to Administrative Agent, for the account of the Lenders, the Fixed Rate Price Adjustment as calculated by Administrative Agent. Such written notice (which shall include calculations in reasonable detail) shall, in the absence of manifest error, be conclusive and binding on the parties hereto.

          (iv) Borrower understands, agrees and acknowledges the following: (A) no Lender has any obligation to purchase, sell and/or match funds in connection with the use of the LIBOR Rate as a basis for calculating the rate of interest on a LIBOR Rate Advance or a Fixed Rate Price Adjustment; (B) the LIBOR Rate is used merely as a reference in determining such rate and/or Fixed Rate Price Adjustment; and (C) Borrower has accepted the LIBOR Rate as a reasonable and fair basis for calculating such rate and a Fixed Rate Price Adjustment. Borrower further agrees to pay the Fixed Rate Price Adjustment and Lender Taxes, if any, whether or not a Lender elects to purchase, sell and/or match funds.

          (k) Withholding Tax Exemption. At least five (5) Business Days prior to the first day on which interest or fees are payable hereunder for the account of any Lender, each Lender that is not incorporated under the laws of the United States of America, or a state thereof, agrees that it will deliver to Administrative Agent and Borrower two (2) duly completed copies of United States Internal Revenue Service Form W-8BEN or Form W-8ECI (and any necessary Form W-8IMY), certifying in either case that such Lender is entitled to receive payments under this Agreement without any deduction or withholding of any United States federal income taxes and a valid and duly completed and executed Internal Revenue Service Form W-8 or W-9. Each Lender which so delivers a Form W-8BEN or Form W-8ECI further undertakes to deliver to Administrative Agent and Borrower two (2) additional copies of such form (or any applicable successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent forms so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by Administrative Agent or Borrower, in each case certifying that such Lender is entitled to receive payments under this Agreement without any deduction or withholding of any United States federal income taxes, unless an event (including, without limitation, any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender advises Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income taxes. If any Lender cannot deliver such form or delivers one or more such forms indicating that such Lender is entitled to only a partial exemption from withholding, then Borrower may withhold from such payments such amounts as are required by the Code.

     2.5. Fees.

          (a) Fees. Borrower shall pay to Administrative Agent the fees in respect of the Commitment pursuant to a separate agreement between Administrative Agent and Borrower.

Page 50

          (b) Facility Fee. Until the Obligations are paid in full and this Agreement is terminated or, if sooner, the date the Commitment terminates, and subject to Section 10.4(b), Borrower shall pay to Administrative Agent, for the account of each Lender, a fee (the “Facility Fee”) in an amount equal to (i) the Commitment multiplied by (ii) the Applicable Facility Fee Rate. The Facility Fee shall be payable, in the manner provided in Section 2.5(e), in arrears on the first Business Day of each Fiscal Quarter, and shall be payable on the Maturity Date or, if sooner, the date the Commitment terminates or on the date of payment in full of all Obligations. The Facility Fee shall be prorated for any period of less than a full Fiscal Quarter.

          (c) Agency Fees. Borrower shall pay Administrative Agent such fees as are provided for in the agency fee agreement between Administrative Agent and Borrower, as in existence from time to time.

          (d) Extension Fee. Borrower shall pay to Administrative Agent, for distribution to each Lender which holds a Pro Rata Share of the Commitment, a fee in an amount equal to, as applicable, (i) 0.25% of the Commitment payable to each such Lender with a Pro Rata Share of the Commitment equal to or greater than $50,000,000, or (ii) 0.15% of the Commitment payable to each such Lender with a Pro Rata Share of the Commitment of less than $50,000,000. Such fee shall be due and payable by Borrower to Administrative Agent for the benefit of the Lenders concurrently with Borrower’s delivery of its written election to extend the Maturity Date pursuant to Section 2.1(d).

          (e) Letter of Credit Fees. The Borrower agrees to pay to the Administrative Agent for the ratable benefit of the Lenders a letter of credit fee in respect of each outstanding Letter of Credit at a rate per annum equal to the greater of (i) the sum of the Applicable LIBOR Rate Margin and the Applicable Facility Fee from time to time in effect multiplied by the Stated Amount of such Letter of Credit or (ii) $1,000. Such letter of credit fee shall be payable quarterly in arrears (for the respective number of days outstanding) on the first Business Day of each Fiscal Quarter during the term of such Letter of Credit, provided that the full amount of such fee shall be immediately due and payable upon any early termination of a Letter of Credit. The Borrower shall pay directly to the Administrative Agent a fronting fee and an issuing fee for its account with respect to each Letter of Credit issued as provided for in a separate agreement between Administrative Agent and borrower, together with, from time to time, on demand all commissions, charges, costs and expenses in the amounts customarily charged by the Administrative Agent from time to time in like circumstances with respect to the issuance of each Letter of Credit, drawings, amendments and other transactions relating thereto.

          (f) Payment of Fees. The fees described in this Section 2.5 represent compensation for services rendered and to be rendered separate and apart from the lending of money or the provision of credit and do not constitute compensation for the use, detention or forbearance of money, and the obligation of Borrower to pay the fees described herein shall be in addition to, and not in lieu of, the obligation of Borrower to pay interest, other fees and expenses otherwise described in this Agreement. All fees shall be payable when due in immediately available funds and shall be nonrefundable when paid. If Borrower fails to make when due, or if no time period is expressed, if not paid within ten (10) days after written demand therefor, any payment of fees or expenses specified or referred to in this Agreement due to Administrative Agent or the Lenders, including without limitation those referred to in this Section 2.5, in

Page 51

Section 11.1, or otherwise under this Agreement or any separate fee agreement between Borrower and Administrative Agent or any Lender relating to this Agreement, such amount shall bear interest from and after demand until paid at the rate specified in Section 2.4(f) (but not to exceed the maximum rate permitted by applicable law), and shall constitute part of the Obligations. The Facility Fee shall be calculated on the basis of a 360-day year and the actual number of days elapsed.

     2.6. Payments.

          (a) Voluntary Prepayments. Subject to Section 2.1(a)(ii)(A)(3), Borrower may, upon prior written notice to Administrative Agent delivered not later than 11:00 A.M. (San Francisco time) not less than one (1) Business Day prior to the proposed prepayment date, at any time and from time to time, prepay any Advances in whole or in part, provided that, notwithstanding the foregoing, Borrower may, upon written notice given not later than 11:00 A.M. (San Francisco time) on the proposed date of repayment, prepay Swing Line Advances in whole or in part on such date. If, at the time of prepayment of the Advances, there are outstanding any Swing Line Advances, such prepayment shall be applied first to the prepayment of outstanding Swing Line Advances, and second to the prepayment of other Advances. Any notice of prepayment given to Administrative Agent under this Section 2.6(a) shall specify the date of prepayment and the aggregate principal amount of the prepayment. In the event of a prepayment of LIBOR Advances, Borrower shall pay any Fixed Rate Price Adjustment payable in respect thereof in accordance with Section 2.4(j). Administrative Agent shall provide to each Lender a confirming copy of such notice on the same Business Day such notice is received.

          (b) Mandatory Prepayment. To the extent Borrower at any time and for any reason is not in compliance with Section 2.1(a)(i)(A)(2), Borrower shall promptly, but in any event within five (5) Business Days, repay Advances outstanding hereunder in an amount sufficient to cause compliance with such Section 2.1(a)(i)(A)(2). All payments under this subsection (b) shall be applied to pay all amounts of excess principal outstanding on the applicable Advances and any applicable Reimbursement Obligations and the remainder, if any, shall be deposited into the Letter of Credit Collateral Account for application to any Reimbursement Obligations as and when due. Provided there is not then existing an Event of Default or an Unmatured Event of Default, the Administrative Agent shall, at the request of the Borrower, release any amounts deposited into the Letter of Credit Collateral Account pursuant to this Section 2.6(b), at such time as Borrower shall regain borrowing capacity pursuant to Section 2.1.

          (c) Manner and Time of Payment. All payments of principal, interest and fees hereunder payable to Administrative Agent or the Lenders shall be made without condition or reservation of right and free of set-off or counterclaim, in Dollars and by wire transfer (pursuant to Administrative Agent’s written wire transfer instructions) of immediately available funds, to Administrative Agent, for the account of each Lender entitled thereto not later than 11:00 A. M. (San Francisco time) on the date due; and funds received by Administrative Agent after that time and date shall be deemed to have been paid on the next succeeding Business Day.

          (d) Payment on Non-Business Days. Whenever any payment to be made by Borrower hereunder shall be stated to be due on a day which is not a Business Day, such

Page 52

payment shall be made on the next succeeding Business Day and such extension of time shall be included in the computation of the payment of interest hereunder and of any of the fees specified in Section 2.5, as the case may be.

     2.7. Notice of Increased Costs. Each Lender agrees that, as promptly as reasonably practicable after it becomes aware of the occurrence of an event or the existence of a condition which would cause it to be affected by any of the events or conditions described in Section 2.4(i) or (j), it will notify Borrower, and provide a copy of such notice to Administrative Agent, of such event and the possible effects thereof, provided that the failure to provide such notice shall not affect such Lender’s rights to reimbursement provided for herein. Provided no Event of Default or Unmatured Event of Default has occurred and is continuing, Borrower shall have the right (the “Payoff Right”) to pay to such Lender all principal, accrued and unpaid interest and any other amounts (collectively, the “Payoff Amount”) due such Lender under this Agreement and the other Loan Documents (including amounts due such Lender under Section 2.4(i)). Borrower may exercise the Payoff Right only by delivering written notice of Borrower’s exercise of such Payoff Right to such Lender, the Administrative Agent and the other Lenders within fifteen (15) days after Borrower’s receipt of written notice from such Lender that Borrower owes amounts under Section 2.4(i) and thereafter paying, in immediately available funds, the Payoff Amount to such Lender within such 15-day period. Upon such Lender’s receipt of the Payoff Amount, such Lender’s Pro Rata Share of the Commitment shall be terminated, the Commitment shall be reduced by an amount equal to such Lender’s Pro Rata Share of the Commitment and the Pro Rata Shares of the Commitment of the remaining Lenders shall be adjusted and the Administrative Agent shall give written notice to each of the Lenders of the adjusted Pro Rata Shares.

     2.8. Voluntary Termination or Reduction of Commitment. At any time prior to the Maturity Date, Borrower may, upon not less than five (5) Business Days’ prior written notice to the Administrative Agent, terminate the Commitment in effect or permanently reduce the Commitment in effect by an aggregate minimum amount of Twenty Million Dollars ($20,000,000) or any multiple of Five Million Dollars ($5,000,000) in excess thereof, provided, however, that no such termination or reduction shall be permitted if, after giving effect thereto and to any prepayment of Advances made on the effective date of such termination or reduction, as the case may be, the then outstanding principal amount of the Advances would exceed the Commitment in effect; provided further, however, that once terminated or reduced in accordance with this Section 2.8, the Commitment in effect may not thereafter be reinstated or increased (provided that, if the Commitment is reduced (but not terminated) pursuant to this Section 2.8, the Commitment may thereafter be increased pursuant to Section 2.9) and provided further, however, that although the Commitment in effect may be terminated entirely pursuant to this Section 2.8, no partial termination shall result in the Commitment being reduced to below One Hundred Million Dollars ($100,000,000). All accrued and unpaid fees due under Section 2.5 with respect to the portion of the Commitment in effect being terminated or reduced shall be paid to the Administrative Agent on the funding date of such termination or reduction.

     2.9. Optional Increase to the Commitment.

          (a) Provided that no Event of Default or Unmatured Event of Default then exists, Borrower may, in accordance with the provisions of this Section 2.9 and on no more than two (2)

Page 53

occasions prior to the date occurring ninety (90) days prior to the original Maturity Date, request in writing that the then effective Commitment be increased up to $400,000,000 minus the amount of any reductions to the Commitment pursuant to Section 2.7 and/or Section 2.8 and the amount of any previous increase in Commitment pursuant to this Section 2.9, provided, however, that no such request shall be for an increase amount less than $20,000,000. Any request under this Section shall be submitted by Borrower to the Lenders through Administrative Agent not less than thirty (30) days prior to the proposed increase, specify the proposed effective date and amount of such increase and be accompanied by (i) an Officer’s Certificate of the REIT stating that no Event of Default or Unmatured Event of Default exists as of the date of the request or will result from the requested increase, (ii) a written consent to the increase in the amount of the Commitment executed by the REIT (in its capacity as “Guarantor” under the Guaranty), and (iii) the satisfaction of all conditions precedent specified in Section 3.2. As a condition to the effectiveness of any such increase, Borrower shall execute such new or replacement Notes as may be requested by Administrative Agent to evidence such increase in the Commitment. Borrower may also specify any fees offered to those Lenders which agree to an increase in the amount of their respective Pro Rata Shares of the Commitment (which fees may be variable based upon the amount which any such Lender is willing to assume as an increase to the amount of its Pro Rata Share of the increased Commitment). The consent of the Lenders, as such, shall not be required for an increase in the amount of the Commitment pursuant to this Section, and this Agreement may be amended for the purpose of implementing any increase of the Commitment in accordance with this Section 2.9 without the consent of any Lender, but subject to Section 2.9(e) below.

          (b) Each Lender may approve or reject a request for an increase in the amount of its Pro Rata Share of the Commitment in its sole and absolute discretion and, absent an affirmative written response within fifteen (15) days after receipt of such request, shall be deemed to have rejected the request. The rejection of such a request by any number of Lenders shall not affect Borrower’s right to increase the Commitment pursuant to this Section as a result of, and with respect to the Pro Rata Shares of, those Lenders that approve such increase and such additional Lenders that join this Agreement in accordance with clause (e) of this Section. Notwithstanding any other provision hereof, no Lender which rejects a request for an increase in the Commitment shall be (i) subject to removal as a Lender, (ii) obligated to lend any amount greater than its original Pro Rata Share of the original Commitment, or (iii) deemed to be in default in any respect hereunder.

          (c) In responding to a request under this Section, each Lender which is willing to increase the amount of its Pro Rata Share of the increased Commitment shall specify the amount of the proposed increase which it is willing to assume. Each consenting Lender shall be entitled to participate ratably (based on its Pro Rata Share of the Commitment before such increase) in any resulting increase in the Commitment, subject to the right of Administrative Agent to adjust allocations of the increased Commitment so as to result in the amounts of the Pro Rata Shares of the Lenders being in integral multiples of $1,000,000.

          (d) If the aggregate principal amount offered to be assumed by the consenting Lenders is less than the amount requested, Borrower may (i) reject the proposed increase in its entirety, (ii) accept the offered amounts or (iii) designate new lenders who qualify as eligible assignees under Section 11.20 and which are reasonably acceptable to Administrative Agent as

Page 54

additional Lenders hereunder in accordance with clause (e) of this Section (each, a “New Lender”), which New Lenders may assume the amount of the increase in the Commitment that has not been assumed by the consenting Lenders.

          (e) Each New Lender designated by Borrower and reasonably acceptable to Administrative Agent shall become an additional party hereto as a New Lender concurrently with the effectiveness of the proposed increase in the Commitment upon its execution of an instrument of joinder to this Agreement which is in form and substance acceptable to Administrative Agent and which, in any event, contains the representations, warranties, indemnities and other protections afforded to Administrative Agent and the other Lenders which would be granted or made by an eligible assignee under Section 11.20 by means of the execution of an Assignment and Assumption.

          (f) Subject to the foregoing, any increase to the Commitment requested under this Section shall be effective as of the date proposed by Borrower and shall be in the principal amount equal to (i) the amount which consenting Lenders are willing to assume as increases to the amount of their respective Pro Rata Shares plus (ii) the amount offered by any New Lenders. Upon the effectiveness of any such increase, Borrower shall issue replacement Notes to each affected Lender and new Notes to each New Lender, and the percentage Pro Rata Share of each Lender will be adjusted, higher or lower as needed, to give effect to the increase in the Commitment and set forth in a new Schedule 1.1 issued by Administrative Agent. On or prior to such effective date and as applicable, certain of the Lenders shall purchase, and certain of the Lenders shall sell, to one another, the percentage interest in the Commitment as necessary in order to reallocate the principal balance under the Notes among the Lenders to correspond to the Pro Rata Shares of the Lenders set forth in the new Schedule 1.1 referred to above.

     2.10. Expiration or Maturity Date of Letters of Credit Past Maturity Date.

     If on the date the Commitments are terminated (whether voluntarily, by reason of the occurrence of an Event of Default or otherwise), there are any Letters of Credit outstanding hereunder, the Borrower shall, on such date, pay to the Administrative Agent an amount of money equal to the Stated Amount of such Letter(s) of Credit for deposit into the Letter of Credit Collateral Account. If a drawing pursuant to any such Letter of Credit occurs on or prior to the expiration date of such Letter of Credit, the Borrower authorizes the Administrative Agent to use the monies deposited in the Letter of Credit Collateral Account to make payment to the beneficiary with respect to such drawing or the payee with respect to such presentment. If no drawing occurs on or prior to the expiration date of such Letter of Credit, the Administrative Agent shall pay to the Borrower (or to whomever else may be legally entitled thereto) the monies deposited in the Letter of Credit Collateral Account (together with any accrued interest thereon) with respect to such outstanding Letter of Credit on or before the date thirty (30) days after the expiration date of such Letter of Credit.

     2.11. Funds Transfer Disbursements. (a) Borrower hereby authorizes Administrative Agent to disburse any Advance pursuant to the Loan Documents, as requested by an authorized representative of Borrower, to any of the account(s) to be designated in the form attached hereto as Exhibit J. Borrower agrees to be bound by any transfer request: (i) authorized or transmitted by Borrower; or (ii) made in Borrower’s name and accepted by Administrative Agent in good

Page 55

faith and in compliance with these transfer instructions, even if not properly authorized by Borrower. Borrower further agrees and acknowledges that Administrative Agent may rely solely on any bank routing number or identifying bank account number or name provided by Borrower to effect a wire or funds transfer even if the information provided by Borrower identifies a different bank or account holder than named by Borrower. Administrative Agent is not obligated or required in any way to take any actions to detect errors in information provided by Borrower. If Administrative Agent takes any actions in an attempt to detect errors in the transmission or content of transfer or requests or takes any actions in an attempt to detect unauthorized funds transfer requests, Borrower agrees that no matter how many times Administrative Agent takes these actions, Administrative Agent will not in any situation be liable for failing to take or correctly perform these actions in the future, and such actions shall not become any part of the transfer disbursement procedures authorized under this provision, the Loan Documents or any agreement between Administrative Agent and Borrower. Borrower agrees to notify Administrative Agent of any errors in the transfer of any funds or of any unauthorized or improperly authorized transfer requests within fourteen (14) days after Administrative Agent’s confirmation to Borrower of such transfer.

          (b) Administrative Agent will, in its sole discretion, determine the funds transfer system and the means by which each transfer will be made. Administrative Agent may delay or refuse to accept a funds transfer request if the transfer would: (i) violate the terms of this authorization, (ii) require use of a bank unacceptable to Administrative Agent or prohibited by government authority, (iii) cause Administrative Agent to violate any Federal Reserve Board or other regulatory risk control program or guideline, or (iii) otherwise cause Administrative Agent to violate any applicable law or regulation.

          (c) Administrative Agent shall not be liable to Borrower or any other parties for (i) errors, acts or failures to act of others, including other entities, banks, communications carriers or clearinghouses, through which Borrower’s transfers may be made or information received or transmitted, and no such entity shall be deemed an agent of Administrative Agent, (ii) any loss, liability or delay caused by fires, earthquakes, wars, civil disturbances, power surges or failures, acts of government, labor disputes, failures in communications networks, legal constraints or other events beyond Administrative Agent’s control, or (iii) any special, consequential, indirect or punitive damages, whether or not (A) any claim for these damages is based on tort or contract or (B) Administrative Agent or Borrower knew or should have known the likelihood of these damages in any situation. Administrative Agent makes no representations or warranties other than those expressly made in this Agreement.

     2.12. Electronic Document Delivery. Documents required to be delivered pursuant to the Loan Documents shall, if available, be delivered by electronic communication and delivery, including, the Internet, e-mail or intranet websites to which the Administrative Agent and each Lender have access (including a commercial, third-party website such as www.Edgar.com <http://www.Edgar.com> or a website sponsored or hosted by the Administrative Agent or the Borrower) provided that the foregoing shall not apply to (A) notices to Administrative Agent or any Lender (or the Issuing Bank) pursuant to Section 2.1 and (B) any Lender that has notified the Administrative Agent and Borrower that it cannot or does not want to receive electronic communications. Notwithstanding the provisions of Section 11.6, the Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it

Page 56

hereunder by electronic delivery pursuant to procedures approved by it for all or particular notices or communications. Documents or notices delivered electronically shall be deemed to have been delivered twenty-four (24) hours after the date and time on which the Administrative Agent or Borrower posts such documents or the documents become available on a commercial website and the Administrative Agent or Borrower notifies each Lender of said posting and provides a link thereto provided if such notice or other communication is not sent or posted during the normal business hours of the recipient, said posting date and time shall be deemed to have commenced as of 9:00 a.m. on the opening of business on the next Business Day for the recipient. Notwithstanding anything contained herein, in every instance the Borrower shall be required to provide paper copies of the Compliance Certificate to the Administrative Agent and shall deliver paper copies of any documents to the Administrative Agent or to any Lender that requests such paper copies until a written request to cease delivering paper copies is given by the Administrative Agent or such Lender. Except for the Compliance Certificate, the Administrative Agent shall have no obligation to request the delivery of or to maintain paper copies of the documents delivered electronically, and in any event shall have no responsibility to monitor compliance by the Borrower with any such request for delivery. Each Lender shall be solely responsible for requesting delivery to it of paper copies and maintaining its paper or electronic documents.

ARTICLE 4
REPRESENTATIONS AND WARRANTIES

     4.1. Representations and Warranties as to Borrower, Etc. In order to induce the Lenders to make the Advances, Borrower hereby represents and warrants to Administrative Agent and the Lenders as follows:

          (a) Organization; Partnership Powers. Borrower (i) is a limited partnership duly organized, validly existing and in good standing under the laws of Maryland, (ii) is duly qualified to do business as a foreign limited partnership and in good standing under the laws of California and each other jurisdiction in which it owns or leases real property or in which the nature of its business requires it to be so qualified, except for those jurisdictions where failure to

Page 59

so qualify and be in good standing would not have a Material Adverse Effect on Borrower, and (iii) has all requisite partnership power and authority to own, operate and encumber its Property and assets and to conduct its business as presently conducted and as proposed to be conducted in connection with and following the consummation of the transactions contemplated by the Loan Documents.

          (b) Authority. Borrower has the requisite partnership power and authority to execute, deliver and perform each of the Loan Documents to which it is a party. The execution, delivery and performance thereof, and the consummation of the transactions contemplated thereby, have been duly authorized by all necessary actions. Each of the Loan Documents to which Borrower is a party has been duly and validly executed and delivered by Borrower and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, subject to bankruptcy, insolvency and other laws affecting creditors’ rights generally and general equitable principles.

          (c) Ownership of Borrower. All of the Partnership Units of Borrower are validly issued and non-assessable and as of the Closing Date are owned of record by the REIT or by the Persons (and in the amounts) set forth on Schedule 4.1(c), as amended from time to time. As of December 31, 2004, the REIT owns 66,325,709 Partnership Units of Borrower, free and clear of any Liens. Such Partnership Units were offered and sold in compliance in all material respects with all Requirements of Law (including, without limitation, federal and state securities laws). Except as set forth in Schedule 4.1(c), as of the Closing Date there are no outstanding securities convertible into or exchangeable for Partnership Units of Borrower, or options, warrants or rights to purchase any such Partnership Units, or commitments of any kind for the issuance of additional Partnership Units or any such convertible or exchangeable securities or options, warrants or rights to purchase such Partnership Units. The REIT is the sole general partner of Borrower.

          (d) No Conflict. The execution, delivery and performance by Borrower of the Loan Documents to which it is or will be a party, and each of the transactions contemplated thereby, do not and will not (i) conflict with or violate Borrower’s limited partnership agreement or certificate of limited partnership or other organizational documents, as the case may be, or (ii) conflict with, result in a breach of or constitute (with or without notice or lapse of time or both) a default under any Requirement of Law, Contractual Obligation or Court Order of or binding upon Borrower, which would have a Material Adverse Effect on Borrower or (iii) require termination of any Contractual Obligation, which termination would have a Material Adverse Effect on Borrower or (iv) result in or require the creation or imposition of any Lien whatsoever upon any of the Properties or assets of Borrower (other than Permitted Liens).

          (e) Consents and Authorizations. Borrower has obtained all consents and authorizations required pursuant to its Contractual Obligations with any other Person, and shall have obtained all consents and authorizations of, and effected all notices to and filings with, any Governmental Authority, as may be necessary to allow Borrower to lawfully execute, deliver and perform its obligations under the Loan Documents to which Borrower is a party, except to the extent that failure to obtain any such consent or authorization or to effect such notice or filing would not have a Material Adverse Effect on Borrower.

Page 60

          (f) Governmental Regulation. Neither Borrower nor the REIT is subject to regulation under the Public Utility Holding Company Act of 1935, the Federal Power Act, the Interstate Commerce Act, the Investment Company Act of 1940 or any other federal or state statute or regulation such that its ability to incur indebtedness is limited or its ability to consummate the transactions contemplated by the Loan Documents is materially impaired.

          (g) Financial Statements; Projections and Forecasts. Each of the financial statements to be delivered to Administrative Agent pursuant to Section 5.1(b) and Section 5.1(c) (i) has been, or will be, as applicable, prepared in accordance with the books and records of the REIT and the Consolidated Entities on a consolidated basis, and (ii) either fairly present in all material respects, or will fairly present in all material respects, as applicable, the financial condition of the REIT and the Consolidated Entities on a consolidated basis, at the dates thereof (and, if applicable, subject to normal year-end adjustments) and the results of its operations and cash flows, on a consolidated basis, for the period then ended. Each of the projections delivered to Administrative Agent prior to the date hereof and each of the projected consolidated cash flows to be delivered to Administrative Agent pursuant to Section 5.1(e), (A) has been, or will be, as applicable, prepared by the REIT in light of the past business and performance of the REIT or its predecessors in interest on a consolidated basis and (B) represent, or will represent, as of the date thereof, the reasonable good faith estimates of the REIT’s financial personnel as of their respective dates.

          (h) Prior Operating Statements. Each of the operating statements pertaining to each of the Unencumbered Assets in the Unencumbered Pool prepared by Borrower and delivered to Administrative Agent prior to the date hereof was prepared in accordance with GAAP in effect on the date such operating statement of each such Unencumbered Asset was prepared and fairly presents the results of operations of such Unencumbered Asset for the period then ended; provided, however, that no representation is made with respect to any period prior to the ownership of such Unencumbered Asset by Borrower.

          (i) Unencumbered Pool Statements and Projections. Each of the Unencumbered Pool Statements to be delivered to Administrative Agent pursuant to Section 5.1(f) (i) has been or will be, as applicable, prepared in accordance with the books and records of the applicable Unencumbered Asset and (ii) fairly presents or will fairly present in all material respects, as applicable, the results of operations of such Unencumbered Asset for the period then ended; provided, however, that no representation is made with respect to any period prior to the ownership of such Unencumbered Asset by Borrower.

          (j) Litigation; Adverse Effects.

          (i) Except as otherwise disclosed on Schedule 4.1(j), there is no action, suit, proceeding, governmental investigation or arbitration, at law or in equity, or before or by any Governmental Authority, pending or, to the best of Borrower’s knowledge, threatened against Borrower or any Property of Borrower which would result in a Material Adverse Effect on Borrower.

          (ii) Borrower is not (A) in violation of any applicable law, which violation has a Material Adverse Effect on Borrower, or (B) subject to or in default with

Page 61

respect to any Court Order which has a Material Adverse Effect on Borrower. There are no material Proceedings pending or, to the best of Borrower’s knowledge, threatened against Borrower or any Unencumbered Asset which would have a Material Adverse Effect on Borrower.

          (k) No Material Adverse Change. Since December 31, 2004, (i) there has occurred no event which has a Material Adverse Effect on Borrower, and (ii) no material adverse change in Borrower’s ability to perform its obligations under the Loan Documents to which it is a party or the transactions contemplated thereby has occurred.

          (l) Payment of Taxes. All tax returns and reports to be filed by Borrower have been timely filed, and all taxes, assessments, fees and other governmental charges shown on such returns or otherwise payable by Borrower have been paid when due and payable (other than real property taxes, which may be paid prior to delinquency so long as no penalty or interest shall attach thereto), except such taxes, if any, as are reserved against in accordance with GAAP and are being contested in good faith by appropriate proceedings or such taxes, the failure to make payment of which when due and payable will not have, in the aggregate, a Material Adverse Effect on Borrower. Borrower has no knowledge of any proposed tax assessment against Borrower that will have a Material Adverse Effect on Borrower, which is not being actively contested in good faith by Borrower.

          (m) Material Adverse Agreements. Borrower is not a party to or subject to any Contractual Obligation or other restriction contained in its limited partnership agreement, certificate of limited partnership or similar governing documents which has a Material Adverse Effect on Borrower.

          (n) Performance. Borrower is not in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in any Contractual Obligation applicable to it, and no condition exists which, with the giving of notice or the lapse of time or both, would constitute a default under such Contractual Obligation, except where the consequences, direct or indirect, of such default or defaults, if any, will not have a Material Adverse Effect on Borrower.

          (o) Federal Reserve Regulations. No part of the proceeds of the Advances hereunder will be used to purchase or carry any “margin security” as defined in Regulation U or for the purpose of reducing or retiring any indebtedness which was originally incurred to purchase or carry any margin security or for any other purpose which might constitute this transaction a “purpose credit” within the meaning of said Regulation U. Neither Borrower nor the REIT is engaged primarily in the business of extending credit for the purpose of purchasing or carrying out any “margin stock” as defined in Regulation U. No part of the proceeds of the Advances hereunder will be used for any purpose that violates, or which is inconsistent with, the provisions of Regulation X or any other regulation of the Federal Reserve Board.

          (p) Disclosure. The representations and warranties of Borrower contained in the Loan Documents and all certificates, financial statements and other documents delivered to Administrative Agent in connection therewith, do not contain any untrue statement of a material fact or omit to state a material fact necessary, in order to make the statements contained herein or

Page 62

therein, in light of the circumstances under which they were made and when taken together with all other information provided by Borrower, not materially misleading; provided no representation is made as to any information in the financial reports for any Real Property prior to its ownership by Borrower. The factual information in any document, certificate or written statement furnished to the Administrative Agent by or on behalf of the REIT or any other Consolidated Entity with respect to the business, assets, prospects, results of operations or financial condition of the REIT, Borrower or any other Consolidated Entity, including operating statements, lease status reports and Rent Rolls for periods when the Real Property covered by such statements or Rent Rolls is owned by Borrower, for use in connection with the transactions contemplated by this Agreement, was true and correct in all material respects as of the applicable date. To the best knowledge of the REIT, Borrower or any Consolidated Entity, there is no occurrence that has had a Material Adverse Effect on Borrower or the REIT or could reasonably be expected to have a Material Adverse Effect on Borrower or the REIT, which has not been disclosed herein or in such other documents, certificates and statements. Notwithstanding the foregoing, with respect to any representations and warranties relating to projections of Borrower’s future performance, such representations and warranties are made in good faith as of the date thereof (it being understood that assumptions as to future results are inherently subject to uncertainty and contingencies, many of which are beyond Borrower’s control, and no assurance can be given that any particular projections will be realized).

          (q) Requirements of Law. The REIT and the Consolidated Entities are in compliance with all Requirements of Law (including without limitation the Securities Act and the Securities Exchange Act, and the applicable rules and regulations thereunder, state securities law and “Blue Sky” laws) applicable to it and its respective businesses, in each case, where the failure to so comply will have a Material Adverse Effect on the REIT or the Borrower. The REIT has obtained all consents of the Commission and has made or will make within the required time periods, all filings required under the Securities Act and the Securities Exchange Act in connection with the execution, delivery and performance by the REIT of the Loan Documents.

          (r) Patents, Trademarks, Permits, Etc. The REIT and the Borrower own, are licensed or otherwise have the lawful right to use, or have, all permits and other governmental approvals, patents, trademarks, trade names, copyrights, technology, know-how and processes used in or necessary for the conduct of each such Person’s business as currently conducted, the absence of which would have a Material Adverse Effect upon Borrower or the REIT. The use of such permits and other governmental approvals, patents, trademarks, trade names, copyrights, technology, know-how and processes by each such Person does not infringe on the rights of any Person subject to such claims and infringements as do not, in the aggregate, give rise to any liability on the part of any such Person which would have a Material Adverse Effect on Borrower or the REIT.

          (s) Environmental Matters. Except as set forth on Schedule 4.1(s) or in any phase I environmental or other reports delivered to Administrative Agent, to the best knowledge of Borrower (i) the operations of the REIT and Borrower comply in all material respects with all applicable, local, state and federal environmental, health and safety Requirements of Law (“Environmental Laws”); (ii) none of the Unencumbered Assets or operations thereon are subject to any Remedial Action or other Liabilities and Costs arising from the Release or threatened

Page 63

Release of a Contaminant into the environment in violation of any Environmental Laws, which Remedial Action or other Liabilities and Costs would have a Material Adverse Effect on Borrower and/or the REIT; (iii) neither the REIT nor Borrower has filed any notice under applicable Environmental Laws reporting a Release of a Contaminant into the environment in violation of any Environmental Laws, except as the same may have been heretofore remedied or would not have a Material Adverse Effect; (iv) there is not now on or in any Unencumbered Assets (except in compliance in all material respects with all applicable Environmental Laws): (A) any underground storage tanks, (B) any asbestos-containing material, or (C) any polychlorinated biphenyls (PCB’s) used in hydraulic oils, electrical transformers or other equipment owned by such Person; and (v) neither the REIT nor Borrower has received any notice or claim to the effect that it is or may be liable to any Person as a result of the Release or threatened Release of a Contaminant into the environment which would have a Material Adverse Effect on Borrower or the REIT.

          (t) Solvency. Borrower is and will be Solvent after giving effect to the disbursements of the Advances and the payment and accrual of all fees then payable.

          (u) Title to Assets. Borrower has good, indefeasible and merchantable title to, or a valid leasehold interest in, all Properties, including, without limitation, all Unencumbered Assets, owned or leased by it.

          (v) Management Agreements. Except as disclosed on Schedule 4.1(v) or as otherwise permitted under the Loan Documents, Borrower is not a party or subject to any management or “ground” leasing agreement with respect to any of the Properties included within the Unencumbered Pool.

     4.2. Representations and Warranties as to the REIT. In order to induce Lenders to make the Advances, Borrower hereby represents and warrants to Administrative Agent and the Lenders as follows:

          (a) Organization: Corporate Powers. The REIT (i) is a corporation duly organized, validly existing and in good standing under the laws of Maryland, (ii) is duly qualified to do business as a foreign corporation and in good standing under the laws of each jurisdiction in which it owns or leases real property or in which the nature of its business requires it to be so qualified, except for those jurisdictions where failure to so qualify and be in good standing will not have a Material Adverse Effect on the REIT, and (iii) has all requisite corporate power and authority to own, operate and encumber its property and assets and to conduct its business as presently conducted and as proposed to be conducted in connection with and following the consummation of the transactions contemplated by the Loan Documents.

          (b) Authority. The REIT has the requisite corporate power and authority to execute, deliver and perform each of the Loan Documents to which it is a party. The execution, delivery and performance thereof, and the consummation of the transactions contemplated thereby, have been duly authorized by the Board of Directors of the REIT, and no other corporate proceedings on the part of the REIT are necessary to consummate such transactions. Each of the Loan Documents to which the REIT is a party has been duly executed and delivered by the REIT and constitutes its legal, valid and binding obligation, enforceable against it in

Page 64

accordance with its terms, subject to bankruptcy, insolvency and other laws affecting creditors’ rights generally and general equitable principles.

          (c) No Conflict. The execution, delivery and performance by the REIT of the Loan Documents to which it is party, and each of the transactions contemplated thereby, do not and will not (i) conflict with or violate its articles of incorporation, by-laws or other organizational documents, (ii) conflict with, result in a breach of or constitute (with or without notice or lapse of time or both) a default under any Requirement of Law, Contractual Obligation or Court Order of or binding upon the REIT, which would have a Material Adverse Effect on the REIT, (iii) require termination of any Contractual Obligation, which termination would have a Material Adverse Effect on the REIT, (iv) result in or require the creation or imposition of any Lien whatsoever upon any of the Properties or assets of the REIT, or (v) require any approval of the stockholders of the REIT.

          (d) Consents and Authorizations.

          (e) Capitalization. All of the capital stock of the REIT has been issued in compliance in all material respects with all applicable Requirements of Law.

Notwithstanding the foregoing, with respect to any representations and warranties relating to projections of the REIT’s future performance, such representations and warranties are made in good faith and based on assumptions believed by the REIT to be reasonable as of the date thereof (it being understood that assumptions as to future results are inherently subject to uncertainty and contingencies, many of which are beyond the REIT’s control, and no assurance can be given that any particular projections will be realized).

Page 85

shall immediately terminate, and/or (ii) declare the unpaid principal amount of, any and all accrued and unpaid interest on the Advances and all of the other Obligations, and an amount equal to all Letter of Credit Liabilities for deposit into the Letter of Credit Collateral Account, to be, and the same shall thereupon be, immediately due and payable with all additional interest from time to time accrued thereon and without presentment, demand, or protest or other requirements of any kind (including without limitation, valuation and appraisement, diligence, presentment, notice of intent to demand or accelerate and of acceleration), all of which are hereby expressly waived by Borrower. Without limiting Administrative Agent’s authority hereunder, on or after the Maturity Date, Administrative Agent shall, at the request, or may, with the consent, of Requisite Lenders exercise any or all rights and remedies under the Loan Documents or applicable law or in equity.

          (b) Access to Information. If an Event of Default then exists, Administrative Agent shall have, in addition to and not by way of a limitation on any other rights and remedies contained in this Agreement or in the other Loan Documents, the right within forty-eight (48) hours after notice to Borrower to obtain access to Borrower’s and the REIT’s records (including computerized information, files and supporting software) relating to the Unencumbered Assets, and its accounting information relating to the Unencumbered Assets, and to use all of the foregoing and the information contained therein in any manner Administrative Agent deems appropriate which is related to the collection of the Obligations. Borrower hereby irrevocably authorizes any accountant or management agent employed by Borrower to deliver such items and information to Administrative Agent. Notwithstanding anything to the contrary contained in the Loan Documents, upon the occurrence of and during the continuance of an Event of Default, Administrative Agent shall be entitled to request and receive, by or through Borrower or appropriate legal process, any and all information concerning operations, business affairs and financial condition of the REIT, Borrower, or any Property of either of them, which is reasonably available to or obtainable by Borrower.

          (d) Waivers, Amendments and Remedies.

Page 86

     9.3. Rescission. If, at any time after acceleration of the maturity of the Advances, Borrower shall pay all arrears of interest and all payments on account of principal of the Advances which shall have become due otherwise than by acceleration (with interest on principal and, to the extent permitted by law, on overdue interest, at the rates specified in this Agreement) and all Events of Default and Unmatured Events of Default (other than nonpayment of principal of and accrued interest on the Advances due and payable solely by virtue of acceleration) shall be remedied or waived pursuant to Section 11.4, then by written notice to Borrower, the Requisite Lenders may elect, in their sole discretion, to rescind and annul the acceleration and its consequences; but such action shall not affect any subsequent Event of Default or Unmatured Event of Default or impair any right or remedy consequent thereon. The provisions of the preceding sentence are intended merely to bind the Lenders to a decision which may be made at the election of the Requisite Lenders; they are not intended to benefit Borrower and do not give Borrower the right to require the Lenders to rescind or annul any acceleration hereunder, even if the conditions set forth herein are met. Borrower shall have no right to enforce this Section 9.3, or to make any claim hereunder, directly, or as a third party beneficiary, or otherwise.

     9.4. Letter of Credit Collateral Account.

          (a) As collateral security for the prompt payment in full when due of all Letter of Credit Liabilities, the Borrower hereby pledges and grants to the Administrative Agent, for the benefit of the Administrative Agent and the Lenders as provided herein, a security interest in all of its right, title and interest in and to the Letter of Credit Collateral Account established pursuant to the requirements of Section 2.10, and the balances from time to time in the Letter of Credit Collateral Account (including the investments and reinvestments therein provided for below), and Borrower shall execute such documents and instruments as requested by Administrative Agent to evidence and/or permit Administrative Agent to perfect such security interest. The balances from time to time in the Letter of Credit Collateral Account shall not constitute payment of any Letter of Credit Liabilities until applied by the Administrative Agent as provided herein. Anything in this Agreement to the contrary notwithstanding, funds held in the Letter of Credit Collateral Account shall be subject to withdrawal only as provided in this Section and in Section 2.10.

          (b) So long as no Unmatured Event of Default or Event of Default exists, the Administrative Agent shall, from time to time, at the request of the Borrower, deliver to the Borrower, against receipt but without any recourse, warranty or representation whatsoever, such of the balances in the Letter of Credit Collateral Account as exceed the aggregate amount of Letter of Credit Liabilities at such time. When all of the Obligations shall have been indefeasibly paid in full and no Letters of Credit remain outstanding, the Administrative Agent shall deliver to the Borrower, against receipt but without any recourse, warranty or representation whatsoever, the balances remaining in the Letter of Credit Collateral Account.

          (c) In the event that the Letter of Credit Collateral Account is funded, the Borrower shall pay to the Administrative Agent from time to time such fees as the Administrative Agent normally charges for similar services in connection with the Administrative Agent’s administration of the Letter of Credit Collateral Account and investments and reinvestments of funds therein.

In performing its functions and duties under this Agreement, Administrative Agent shall act solely as Administrative Agent of the Lenders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for Borrower or any other Person.

     10.2. Nature of Duties. Administrative Agent shall not have any duties or responsibilities except those expressly set forth in this Agreement or in the other Loan Documents. The duties of Administrative Agent shall be administrative in nature. Subject to the provisions of Sections 10.5 and 10.7, Administrative Agent shall administer the Advances in the same manner as it administers its own loans. Promptly following the effectiveness of this Agreement, Administrative Agent shall send to each Lender its originally executed Note and the executed original, to the extent the same are available in sufficient numbers, of each other Loan Document other than the Notes in favor of the other Lenders and filed or recorded security documents or instruments, with the latter to be held and retained by Administrative Agent for the benefit of all the Lenders. Administrative Agent shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender. Nothing in this Agreement or any of the other Loan Documents, expressed or implied, is intended or shall be construed to impose upon Administrative Agent any obligation in respect of this Agreement or any of the other Loan Documents except as expressly set forth herein or therein. Each Lender shall make its own independent investigation of the financial condition and affairs of the REIT and Borrower in connection with the making and the continuance of the Advances hereunder and shall make its own appraisal of the creditworthiness of the REIT and Borrower, and, except as specifically provided herein, Administrative Agent shall not have any duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before the Closing Date or at any time or times thereafter.

     10.3. Disbursements of Advances.

          (a) Promptly, but in any event not later than 5:00 P.M. (San Francisco time) on the same Business Day on which Administrative Agent receives a Notice of Borrowing, Administrative Agent shall send a copy thereof by facsimile to each other Lender and shall otherwise notify each Lender of the proposed Advance and the Funding Date. Each Lender shall make available to Administrative Agent (or the funding bank or entity designated by Administrative Agent), the amount of such Lender’s Pro Rata Share of such Advance in immediately available funds not later than the times designated in Section 10.3(b). Unless Administrative Agent shall have been notified by any Lender not later than the close of business (San Francisco time) on the Business Day immediately preceding the Funding Date in respect of any Advance that such Lender does not intend to make available to Administrative Agent such Lender’s Pro Rata Share of such Advance, Administrative Agent may assume that such Lender shall make such amount available to Administrative Agent. If any Lender does not notify Administrative Agent of its intention not to make available its Pro Rata Share of such Advance as described above, but does not for any reason make available to Administrative Agent such Lender’s Pro Rata Share of such Advance, such Lender shall pay to Administrative Agent forthwith on demand such amount, together with interest thereon at the Federal Funds Rate. In any case where a Lender does not for any reason make available to Administrative Agent such Lender’s Pro Rata Share of such Advance, Administrative Agent, in its sole discretion, may, but shall not be obligated to, fund to Borrower such Lender’s Pro Rata Share of such Advance. If Administrative Agent funds to Borrower such Lender’s Pro Rata Share of such Advance and if such Lender subsequently pays to Administrative Agent such corresponding amount, such amount so paid shall constitute such Lender’s Pro Rata Share of such Advance. Nothing in this Section 10.3(a) shall alter the respective rights and obligations of the parties hereunder in respect of a Defaulting Lender or a Non-Pro Rata Advance.

          (b) Requests by Administrative Agent for funding by the Lenders of Advances will be made by telecopy. Each Lender shall make the amount of its Advance available to Administrative Agent in Dollars and in immediately available funds, to such bank and account, in El Segundo, California as Administrative Agent may designate, not later than 9:00 A.M. (San Francisco time) on the Funding Date designated in the Notice of Borrowing with respect to such Advance, but in no event earlier than two (2) Business Days following such Lender’s receipt of the applicable Notice of Borrowing.

          (c) Swing Line Advances.

               (i) With respect to Swing Line Advances, if,

          (A) as of 10:00 A.M. (San Francisco time) on the fourth (4^th) Business Day after the Swing Line Lender has funded any Swing Line Advance (the date such Swing Line Advance was funded, the “Swing Line Funding Date”), Borrower has neither (1) repaid such Swing Line Advance in full, nor (2) notified the Swing Line Lender in writing that Borrower intends to repay such Swing Line Advance in full on the next Business Day, nor (3) timely delivered a Notice of Borrowing requesting a proposed Funding Date, no later than the fifth (5^th) Business Day after such Swing Line Funding Date, with respect to an Advance in a principal amount sufficient to repay such Swing Line Advance in full; or

Page 89

          (B) as of 11:00 A.M. on the fifth (5^th) Business Day after such Swing Line Funding Date, (1) Borrower has not repaid such Swing Line Advance in full, or (2) the conditions precedent to any requested Advance the proceeds of which were to have been used (in whole or in part) to repay such Swing Line Advance have not been satisfied; or

          (C) at any time prior to the repayment of any Swing Line Advance, an Event of Default shall have occurred or the Advances shall be accelerated, or the Maturity Date shall occur, for any reason whatsoever; then

               the Swing Line Lender shall promptly (or, if an Event of Default has occurred but the Advances have not been accelerated and the Maturity Date has not occurred, may) notify each Lender by telephone (confirmed promptly by telex, facsimile transmission or cable), telex, facsimile transmission, or cable of the amount of such Swing Line Advance; and each Lender shall (1) in a case described in clause (A) above, before 10:00 A.M. (San Francisco time) on the next Business Day, or (2) in a case described in clause (B) or clause (C) above, before 12:00 noon (San Francisco time) on the date of such notice, pay to the Swing Line Lender, to such bank and account in El Segundo, California (or to such bank and account in such other place) as the Swing Line Lender may designate, in immediately available funds, such Lender’s Pro Rata Share of the principal amount of such Swing Line Advance.

               (ii) Upon funding in accordance with clause (i) above, each Lender shall be deemed to have acquired from the Swing Line Lender (and the Swing Line Lender shall be deemed to have assigned to each such Lender) a percentage interest in such Swing Line Advance equal to such Lender’s Pro Rata Share, and, for purposes of determining the availability of Swing Line Advances or Advances, such Swing Line Advance shall be deemed an Advance (and no longer a Swing Line Advance); provided that the obligations of the Lenders under this Section 10.3(c) shall not be subject to the notice or amount requirements, or to satisfaction of conditions precedent, otherwise applicable to the making of Advances.

               (iii) Each Lender’s obligation to fund, and to purchase from the Swing Line Lender, its Pro Rata Share of a Swing Line Advance pursuant to this Section 10.3(c) shall be absolute and unconditional under any and all circumstances (including, without limitation, irrespective of any intervening bankruptcy of Borrower or acceleration of the Advances).

               (iv) It is not the parties’ intent that the obligations of the Lenders under this Section 10.3(c) constitute guaranties or obligations of suretyship. If and to the extent, however, that the obligations of any Lender under this Section 10.3(c) are determined to be those of a guarantor or surety, such Lender, with full knowledge of the consequences thereof, hereby expressly waives the benefit of each and every right or defense of a guarantor or surety the effect of which would relieve such Lender of all or any portion of its obligations under this Section 10.3(c).

               (v) In the event that any Lender fails to pay to the Swing Line Lender when due any amount it is required to fund under this Section 10.3(c), such Lender and

Page 90

Borrower severally agree to pay to the Swing Line Lender , on demand, the amount such Lender has failed to so pay, together with interest thereon for each day from the date on which such payment was due until the date such amount is repaid to the Administrative Agent, at (A) in the case of Borrower, the Base Rate, or (B) in the case of such Lender, the Federal Funds Rate. Any such repayment by Borrower shall be without prejudice to any rights it may have against the Lender that has failed to pay when due any such amount.

          (d) Nothing in this Section 10.3 shall be deemed to relieve any Lender of its obligation (subject only to Section 2.1(b)(iii) in respect of the initial funding of Swing Line Advances) hereunder to make its Pro Rata Share of any Advance on the applicable Funding Date, nor shall any Lender be responsible for the failure of any other Lender to perform its obligations to make any Advance hereunder, and the Pro Rata Share of any Lender shall not be increased or decreased as a result of the failure by any other Lender to perform its obligation to make an Advance.

     10.4. Distribution and Apportionment of Payments.

          (a) Subject to Section 10.4(b), payments actually received by Administrative Agent for the account of the Lenders shall be paid to them promptly after receipt thereof by Administrative Agent, but in any event within one (1) Business Day, provided that Administrative Agent shall pay to the Lenders interest thereon, at the Federal Funds Rate, from the Business Day following receipt of such funds by Administrative Agent until such funds are paid in immediately available funds to the Lenders. Subject to Section 10.4(b) all payments of principal and interest in respect of outstanding Advances, all payments of the fees described in this Agreement, and all payments in respect of any other Obligations shall be allocated among such Lenders as are entitled thereto, in proportion to their respective Pro Rata Shares or otherwise as provided herein. Administrative Agent shall promptly distribute, but in any event within one (1) Business Day after it receives the same, to each Lender at its primary address set forth on the appropriate signature page hereof or on the Assignment and Assumption, or at such other address as a Lender may request in writing, such funds as it may be entitled to receive; provided that Administrative Agent shall in any event not be bound to inquire into or determine the validity, scope or priority of any interest or entitlement of any Lender and may suspend all payments and seek appropriate relief (including, without limitation, instructions from Requisite Lenders or all the Lenders, as applicable, or an action in the nature of interpleader) in the event of any doubt or dispute as to any apportionment or distribution contemplated hereby. The order of priority herein is set forth solely to determine the rights and priorities of the Lenders as among themselves and may at any time or from time to time be changed by the Lenders as they may elect, in writing in accordance with Section 11.4, without necessity of notice to or consent of or approval by Borrower or any other Person. All payments or other sums received by Administrative Agent for the account of the Lenders (including, without limitation, principal and interest payments) shall not constitute property or assets of the Administrative Agent and shall be held by Administrative Agent, solely in its capacity as Administrative Agent for itself and the other Lenders, subject to the Loan Documents.

          (b) Notwithstanding any provision hereof to the contrary, until such time as a Defaulting Lender has funded its Pro Rata Share of any Advance which was previously a Non-

Page 91

Pro Rata Advance, or all the other Lenders have received payment in full (whether by repayment or prepayment) of the principal and interest due in respect of such Non-Pro Rata Advance, all of the Obligations owing to such Defaulting Lender hereunder shall be subordinated in right of payment, as provided in the following sentence, to the prior payment in full of all principal, interest and fees in respect of all Non-Pro Rata Advances in which the Defaulting Lender has not funded its Pro Rata Share (such principal, interest and fees being referred to as “Senior Loans”). All amounts paid by Borrower and otherwise due to be applied to the Obligations owing to the Defaulting Lender pursuant to the terms hereof shall be distributed by Administrative Agent to the other Lenders in accordance with their respective Pro Rata Shares (recalculated for purposes hereof to exclude the Defaulting Lender’s Pro Rata Share of the Commitment), until all Senior Loans have been paid in full. This provision governs only the relationship among Administrative Agent, each Defaulting Lender and the other Lenders; nothing hereunder shall limit the obligation of Borrower to repay all Advances in accordance with the terms of this Agreement, nor create an Event of Default if payments are not made to a Defaulting Lender. The provisions of this Section shall apply and be effective regardless of whether an Event of Default occurs and is then continuing, and notwithstanding (i) any other provision of this Agreement to the contrary, (ii) any instruction of Borrower as to its desired application of payments or (iii) the suspension of such Defaulting Lender’s right to vote on matters which are subject to the consent or approval of the Requisite Lenders or all the Lenders. No Facility Fee shall accrue in favor of, or be payable to, such Defaulting Lender from the date of any failure to fund Advances or reimburse Administrative Agent for any Liabilities and Costs as herein provided until such failure has been cured, and Administrative Agent shall be entitled to (A) withhold or setoff, and to apply to the payment of the defaulted amount and any related interest, any amounts to be paid to such Defaulting Lender under this Agreement, and (B) bring an action or suit against such Defaulting Lender in a court of competent jurisdiction to recover the defaulted amount and any related interest. In addition, the Defaulting Lender shall indemnify, defend and hold Administrative Agent and each of the other Lenders harmless from and against any and all Liabilities and Costs, plus interest thereon at the Default Rate, which they may sustain or incur by reason of or as a direct consequence of the Defaulting Lender’s failure or refusal to abide by its obligations under this Agreement.

     10.5. Rights, Exculpation, Etc. Neither Administrative Agent, any Affiliate of Administrative Agent, nor any of their respective officers, directors, employees, agents, attorneys or consultants, shall be liable to any Lender for any action taken or omitted by them under this Agreement or under any of the other Loan Documents, or in connection herewith or therewith, except that Administrative Agent shall be liable for its gross negligence or willful misconduct. Administrative Agent shall not be responsible to any Lender for any recitals, statements, representations or warranties herein or for the execution, effectiveness, genuineness, validity, enforceability, collectability or sufficiency of this Agreement, or any of the other Loan Documents, or any of the transactions contemplated hereby and thereby; or for the financial condition of the REIT, Borrower or any of their Affiliates. Administrative Agent shall not be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement or any of the other Loan Documents or the financial condition of the REIT, Borrower or any of their Affiliates, or the existence or possible existence of any Unmatured Event of Default or Event of Default.

Page 92

     10.6. Reliance. Administrative Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents, telecopies or any telephone message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and with respect to all matters pertaining to this Agreement or any of the other Loan Documents and its duties hereunder or thereunder, upon advice of legal counsel (including counsel for Borrower), independent public accountants and other experts selected by it.

     10.7. Indemnification. To the extent that Administrative Agent is not reimbursed and indemnified by Borrower, the Lenders will reimburse, within ten (10) Business Days after notice from Administrative Agent, and indemnify and defend Administrative Agent from and against any and all Liabilities and Costs which may be imposed on, incurred by, or asserted against it in any way relating to or arising out of its role as Administrative Agent under this Agreement, or any of the other Loan Documents or any action taken or omitted by Administrative Agent under this Agreement, or any of the other Loan Documents, in proportion to each Lender’s Pro Rata Share; provided that no Lender shall be liable for any portion of such Liabilities and Costs resulting from Administrative Agent’s gross negligence or willful misconduct. The obligations of the Lenders under this Section 10.7 shall survive the payment in full of all Obligations and the termination of this Agreement. In the event that after payment and distribution of any amount by Administrative Agent to the Lenders, any Lender or third party, including Borrower, any creditor of Borrower or a trustee in bankruptcy, recovers from Administrative Agent any amount found to have been wrongfully paid to Administrative Agent or disbursed by Administrative Agent to the Lenders, then the Lenders, in proportion to their respective Pro Rata Shares, shall reimburse Administrative Agent for all such amounts. Notwithstanding the foregoing, Administrative Agent shall not be obligated to advance Liabilities and Costs and may require the deposit by each Lender of its Pro Rata Share of any material Liabilities and Costs reasonably anticipated by Administrative Agent before they are incurred, made or payable.

     10.8. Administrative Agent Individually. With respect to its Pro Rata Share of the Commitment and the Advances made by it, Administrative Agent shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set forth herein for any other Lender. Administrative Agent and any Lender and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of banking, trust or other business with the REIT, Borrower or any of their respective Affiliates as if it were not acting as Administrative Agent or a Lender pursuant hereto.

     10.9. Successor Administrative Agent; Resignation of Administrative Agent; Removal of Administrative Agent.

          (a) Administrative Agent may resign from the performance of all its functions and duties hereunder at any time by giving at least thirty (30) Business Days’ prior written notice to the Lenders and Borrower, and shall automatically cease to be Administrative Agent hereunder in the event a petition in bankruptcy shall be filed by or against Administrative Agent or the Federal Deposit Insurance Corporation or any other Governmental Authority shall assume control of Administrative Agent or Administrative Agent’s interests under this Agreement and the other Loan Documents. Further, the Requisite Lenders (other than Administrative Agent) may remove Administrative Agent at any time based upon Administrative Agent’s gross negligence or willful misconduct by giving at least thirty (30) Business Days’ prior written

Page 93

notice to Administrative Agent, Borrower and all other Lenders. Such resignation or removal shall take effect upon the acceptance by a successor Administrative Agent of appointment pursuant to subsection (b) or (c) below.

          (b) Upon any such notice of resignation by or removal of Administrative Agent, the Requisite Lenders shall appoint a successor Administrative Agent which appointment shall be subject to Borrower’s consent (other than upon the occurrence and during the continuance of any Event of Default), which shall not be unreasonably withheld or delayed. Any successor Administrative Agent must be a Lender (i) the senior debt obligations of which (or such Lender’s parent’s senior unsecured debt obligations) are rated not less than Baa-2 by Moody’s Investors Service, Inc. or a comparable rating by a rating agency acceptable to the Requisite Lenders and (ii) which has total assets in excess of Ten Billion Dollars ($10,000,000,000). Such successor Administrative Agent shall separately confirm in writing with Borrower the fee to be paid to such Administrative Agent pursuant to Section 2.5(c).

          (c) If a successor Administrative Agent shall not have been so appointed within said thirty (30) Business Day period, the retiring or removed Administrative Agent, with the consent of Borrower (other than upon the occurrence and during the continuance of any Event of Default)(which may not be unreasonably withheld or delayed), shall then appoint a successor Administrative Agent who shall meet the requirements described in subsection (b) above and who shall serve as Administrative Agent until such time, if any, as the Requisite Lenders, with the consent of Borrower (other than upon the occurrence and during the continuance of any Event of Default), appoint a successor Administrative Agent as provided above.

          (d) Each successor Administrative Agent appointed pursuant to this Section 10.9 shall concurrently assume the rights and obligations of the Swing Line Lender under this Agreement (including the Swing Line Lender’s commitment to fund Swing Line Advances and its interest in outstanding advances under the Swing Line) and the rights and obligations of Administrative Agent with respect to the Letters of Credit. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent and Swing Line Lender, and the retiring Administrative Agent and Swing Line Lender shall be discharged from its duties and obligations under this Administrative Agreement. Notwithstanding any provision of Section 11.20 to the contrary, the commitment of the Swing Line Lender to fund Swing Line Advances and the Swing Line Lender’s interest in outstanding Swing Line Advances may not be assigned to any Person other than a Person who concurrently becomes both a successor Administrative Agent pursuant to this Section 10.9 and the Swing Line Lender.

     10.10. Consent and Approvals.

          (a) In addition to any other term or provision of this Agreement which requires the consent or approval of, or other action by, the Requisite Lenders, each consent, approval, amendment, modification or waiver specifically enumerated in this Section 10.10(a) shall require the consent of the Requisite Lenders:

Page 94

               (i) Approval of any amendment of organizational documents (to the extent required by Section 7.2);

               (ii) Acceleration following an Event of Default (Section 9.2(a)) or rescission of such acceleration (Section 9.3);

               (iii) Approval of the exercise of rights and remedies under the Loan Documents following an Event of Default (Section 9.2(a));

               (iv) Approval of a change in the method of calculation of any financial covenants, standards or terms as a result of a change in GAAP (Section 11.3); and

               (v) Except as referred to in subsection (b) below, approval of any amendment, modification or termination of this Agreement, or waiver of any provision herein.

          (b) Each consent, approval, amendment, modification or waiver specifically enumerated in Section 11.4 shall require the consent of all the Lenders.

          (c) In addition to the required consents or approvals referred to in subsection (a) above, Administrative Agent may at any time request instructions from Requisite Lenders with respect to any actions or approvals which, by the terms of this Agreement or of any of the Loan Documents, Administrative Agent is permitted or required to take or to grant without instructions from Lenders and if such instructions are promptly requested, Administrative Agent shall be absolutely entitled to refrain from taking any action or to withhold any approval and shall not be under any liability whatsoever to any Person for refraining from taking any action or withholding any approval under any of the Loan Documents until it shall have received such instructions from the Requisite Lenders. Without limiting the foregoing, no Lender shall have any right of action whatsoever against Administrative Agent as a result of Administrative Agent acting or refraining from acting under this Agreement, or any of the other Loan Documents in accordance with the instructions of the Requisite Lenders or, where applicable, all the Lenders. Administrative Agent shall promptly notify each Lender at any time that the Requisite Lenders have instructed Administrative Agent to act or refrain from acting pursuant hereto.

          (d) Each Lender agrees that any action taken by Administrative Agent at the direction or with the consent of the Requisite Lenders in accordance with the provisions of this Agreement or any Loan Document, and the exercise by Administrative Agent at the direction or with the consent of the Requisite Lenders of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all the Lenders, except for actions specifically requiring the approval of all the Lenders. All communications from Administrative Agent to the Lenders requesting Lenders’ determination, consent, approval or disapproval (i) shall be given in the form of a written notice to each Lender, (ii) shall be accompanied by a description of the matter or thing as to which such determination, approval, consent or disapproval is requested, or shall advise each Lender where such matter or thing may be inspected, or shall otherwise describe the matter or issue to be resolved, (iii) shall include, if reasonably requested by a Lender and to the extent not previously provided to such Lender, written materials and a summary of all oral information provided to Administrative

Page 95

Agent by Borrower in respect of the matter or issue to be resolved, and (iv) shall include Administrative Agent’s recommended course of action or determination in respect thereof. Each Lender shall reply promptly, but in any event within ten (10) Business Days or such other applicable response period as expressly set forth in this Agreement (the “Lender Reply Period”). Unless a Lender shall give written notice to Administrative Agent that it objects to the recommendation or determination of Administrative Agent (together with a written explanation of the reasons behind such objection) within the Lender Reply Period, such Lender shall be deemed to have approved of or consented to such recommendation or determination and Borrower and each other Lender may rely on such approval as if given. With respect to decisions requiring the approval of the Requisite Lenders or all the Lenders, Administrative Agent shall submit its recommendation or determination for approval of or consent to such recommendation or determination to all the Lenders and upon receiving the required approval or consent shall follow the course of action or determination recommended to the Lenders by Administrative Agent or such other course of action recommended by the Requisite Lenders, and each non-responding Lender shall be deemed to have concurred with such recommended course of action.

     10.11. Certain Agency Provisions Relating to Enforcement. Should Administrative Agent (i) employ counsel for advice or other representation (whether or not any suit has been or shall be filed) with respect to any of the Loan Documents, or (ii) commence any proceeding or in any way seek to enforce its rights or remedies under the Loan Documents, each Lender, upon demand therefor from time to time, shall contribute its share (based on its Pro Rata Share) of the reasonable costs and/or expenses of any such advice or other representation or enforcement, including, but not limited to, court costs, title company charges, filing and recording fees, appraisers’ fees and fees and expenses of attorneys to the extent not otherwise reimbursed by Borrower, provided that Administrative Agent shall not be entitled to reimbursement of its attorneys’ fees and expenses incurred in connection with the resolution of disputes between Administrative Agent and other Lenders unless Administrative Agent shall be the prevailing party in any such dispute. Any loss of principal and/or interest resulting from any Event of Default shall be shared by the Lenders in accordance with their respective Pro Rata Shares. It is understood and agreed that in the event Administrative Agent determines it is necessary to engage counsel for the Lenders from and after the occurrence of an Event of Default, said counsel shall be selected by Administrative Agent.

     10.12. Ratable Sharing. Subject to Sections 10.3 and 10.4 the Lenders agree among themselves that (i) with respect to all amounts received by them which are applied to the payment of the Obligations, equitable adjustment will be made so that, in effect, all such amounts will be shared among them ratably in accordance with their Pro Rata Shares, whether received by voluntary payment, by counterclaim or cross action or by the enforcement of any or all of the Obligations, (ii) if any of them shall by voluntary payment or by the exercise of any right of counterclaim or otherwise, receive payment of a proportion of the aggregate amount of the Obligations held by it which is greater than its Pro Rata Share of the payments on account of the Obligations, the one receiving such excess payment shall purchase, without recourse or warranty, an undivided interest and participation (which it shall be deemed to have done simultaneously upon the receipt of such payment) in such Obligations owed to the others so that all such recoveries with respect to such Obligations shall be applied ratably in accordance with their Pro Rata Shares; provided, that if all or part of such excess payment received by the

Page 96

purchasing party is thereafter recovered from it, those purchases shall be rescinded and the purchase prices paid for such participations shall be returned to that party to the extent necessary to adjust for such recovery, but without interest except to the extent the purchasing party is required to pay interest in connection with such recovery. Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 10.12 may, to the fullest extent permitted by law, exercise all its rights of payment with respect to such participation as fully as if such Lender were the direct creditor of Borrower in the amount of such participation. No Lender shall exercise any setoff, banker’s lien or other similar right in respect to any Obligations without the prior written approval by Administrative Agent.

     10.13. Delivery of Documents. Administrative Agent shall, as soon as reasonably practicable, distribute to each Lender at its primary address set forth on the appropriate counterpart signature page hereof, or at such other address as a Lender may request in writing, (i) copies of all documents to which such Lender is a party or of which such Lender is a beneficiary, (ii) all documents of which Administrative Agent receives copies from Borrower pursuant to Sections 5.1 and 11.6, (iii) all other documents or information which Administrative Agent is required to send to the Lenders pursuant to the terms of this Agreement, (iv) all other information or documents received by Administrative Agent at the request of any Lender, and (v) all notices received by Administrative Agent pursuant to Section 5.2. In addition, within fifteen (15) Business Days after receipt of a request in writing from a Lender for written information or documents provided by or prepared by Borrower, the REIT or any Consolidated Entity, Administrative Agent shall deliver such written information or documents to such requesting Lender if Administrative Agent has possession of such written information or documents in its capacity as Administrative Agent or as a Lender.

     10.14. Notice of Events of Default. Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Unmatured Event of Default or Event of Default (other than nonpayment of principal of or interest on the Advances) unless Administrative Agent has received notice in writing from a Lender or Borrower describing such event or condition and expressly stating that such notice is a notice of an Unmatured Event of Default or Event of Default. Should Administrative Agent receive such notice of the occurrence of an Unmatured Event of Default or Event of Default, or should Administrative Agent send Borrower a notice of Unmatured Event of Default or Event of Default, Administrative Agent shall promptly give notice thereof to each Lender. If any individual employed by any Lender who is responsible for managing, or otherwise involved in, the relationship between such Lender and Borrower in connection with this Agreement or such Lender and Administrative Agent in connection with this Agreement, has or acquires actual knowledge of an Unmatured Event of Default or Event of Default, such Lender shall promptly give written notice thereof to Administrative Agent.

     10.15. Documentation and Syndication Agents. Notwithstanding anything contained herein which may be construed to the contrary, the Documentation Agents and Syndication Agents shall not exercise any of the rights or have any of the responsibilities of the Administrative Agent hereunder, or any other rights or responsibilities other than their respective rights and responsibilities as Lenders hereunder.

     11.2. Indemnity. Borrower further agrees to defend, protect, indemnify and hold harmless Administrative Agent, each and all of the Lenders, each of their respective Affiliates and each of the respective officers, directors, employees, agents, attorneys and consultants (including, without limitation, those retained in connection with the satisfaction or attempted satisfaction of any of the conditions set forth in Article 3) of each of the foregoing (collectively called the “Indemnitees”) from and against any and all Liabilities and Costs imposed on, incurred by, or asserted against such Indemnitees (whether based on any federal or state laws or other statutory regulations, including, without limitation, securities and commercial laws and regulations, under common law or in equity, and based upon contract or otherwise, including any liability and costs arising as a result of a “prohibited transaction” under ERISA to the extent arising from or in connection with the past, present or future operations of the REIT or Borrower or their respective predecessors in interest) in any manner relating to or arising out of this Agreement or the other Loan Documents, or any act, event or transaction related or attendant

Page 98

thereto, the making of and participation in the Advances and the management of the Advances, or the use or intended use of the proceeds of the Advances (collectively, the “Indemnified Matters”); provided, however, that Borrower shall have no obligation to an Indemnitee hereunder with respect to (a) matters for which such Indemnitee has been compensated pursuant to any provision of this Agreement, and (b) Indemnified Matters to the extent caused by or resulting from the willful misconduct or gross negligence of that Indemnitee, as determined by a court of competent jurisdiction. To the extent that the undertaking to indemnify, pay and hold harmless set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, Borrower shall contribute the maximum portion which it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Matters incurred by the Indemnitees.

     11.3. Change in Accounting Principles and “Funds from Operations” Definition. Except as otherwise provided herein, if any changes in accounting principles from those used in the preparation of the most recent financial statements delivered to Administrative Agent pursuant to the terms hereof are hereafter required or permitted by the rules, regulations, pronouncements and opinions of the Financial Accounting Standards Board or the American Institute of Certified Public Accountants (or successors thereto or agencies with similar functions) and are adopted by the REIT or Borrower with the agreement of its Accountants and such changes result in a change in the method of calculation of any of the financial covenants, standards or terms found herein, the parties hereto agree to enter into negotiations in order to amend such provisions so as to equitably reflect such changes with the desired result that the criteria for evaluating the financial condition of the REIT and the Consolidated Entities shall be the same after such changes as if such changes had not been made; provided, however, that no change in GAAP that would affect the method of calculation of any of the financial covenants, standards or terms shall be given effect in such calculations until such provisions are amended, in a manner satisfactory to the Requisite Lenders, to so reflect such change in accounting principles. The definition of “Funds from Operations” set forth in Article 1 is based upon the definition of “Funds From Operations” promulgated by the National Association of Real Estate Investment Trusts and effective as of April 5, 2002 (the “NAREIT Definition”). If the NAREIT Definition is modified after the date of this Agreement, the parties hereto agree to enter into negotiations if any party so requests in order to amend the definition of “Funds from Operations” set forth in this Agreement to make it consistent with the modified NAREIT Definition; provided, however, that no change in such definition of “Funds from Operations” shall be given effect until such definition is amended, in a manner satisfactory to Requisite Lenders, to so reflect such modification in the NAREIT Definition of “Funds From Operations”.

     11.4. Amendments and Waivers.

          (a) No amendment or modification of any provision of this Agreement shall be effective without the written agreement of Requisite Lenders and Borrower (except for amendments to Section 10.4(a) which do not require the consent of Borrower), and (b) no termination or waiver of any provision of this Agreement, or consent to any departure by Borrower therefrom, shall in any event be effective without the written concurrence of the Requisite Lenders (after notice to all the Lenders), which the Requisite Lenders shall have the right to grant or withhold at their sole discretion, except that

Page 99

          (A) the following amendments, modifications or waivers shall require the consent of Requisite Lenders (which Requisite Lenders must include Wells Fargo):

               (i) changing any provision contained in Section 8.2, Section 8.5 or in Section 8.9; or

               (ii) changing the definitions of “Total Liabilities,” “Gross Asset Value,” “Unencumbered Asset Value,” “Unencumbered Pool,” or “Debt”, or the definition of any defined term used in any of the foregoing definitions; or

               (iii) subject to clause (B)(ix) below, amending or otherwise modifying the Guaranty; and

          (B) the following amendments, modifications or waivers shall require the consent of all the Lenders:

               (i) increasing or reducing the Commitment and/or any Lender’s Pro Rata Share of the Commitment, except as otherwise provided in, and subject to the terms and conditions of Section 2.8, Section 2.9 or Section 11.20;

               (ii) changing the principal amount or final maturity of the Advances or otherwise changing the Maturity Date, except as otherwise provided in, and subject to the terms and conditions of Section 2.1(d) or Section 2.8;

               (iii) reducing the interest rates applicable to the Advances;

               (iv) reducing the rates on which fees payable pursuant hereto are determined;

               (v) forgiving or delaying any amount payable or receivable under Article 2;

               (vi) changing the definition of “Requisite Lenders” or “Pro Rata Shares”;

               (vii) changing any provision contained in this Section 11.4;

               (viii) releasing any obligor under any Loan Document, unless such release is otherwise required or permitted by the terms of this Agreement;

               (ix) extending the expiration date of any Letter of Credit beyond the Maturity Date;

               (x) materially amending or otherwise materially modifying the Guaranty; or

               (xi) consenting to assignment by Borrower of all of its duties and Obligations hereunder pursuant to Section 11.14.

Page 100

     No amendment, modification, termination or waiver of any provision of Article 10 or any other provision referring to Administrative Agent shall be effective without the written concurrence of Administrative Agent, but only if such amendment, modification, termination or waiver alters the obligations or rights of Administrative Agent. Any waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given. No notice to or demand on Borrower in any case shall entitle Borrower to any other further notice or demand in similar or other circumstances. Any amendment, modification, termination, waiver or consent effected in accordance with this Section 11.4 shall be binding on each assignee, transferee or recipient of Administrative Agent’s or any Lender’s Pro Rata Share of the Commitment under this Agreement or the Advances at the time outstanding. Borrower shall be entitled to rely on any amendment or waiver executed by the Administrative Agent on behalf of the Lenders provided that Administrative Agent certifies to Borrower that Administrative Agent obtained the approvals or consents required under this Agreement of the Requisite Lender or all the Lenders, as the case may be.

          (b) In connection with (i) any proposed amendment, modification or waiver for which the unanimous consent of the Lenders is required, and such consents have been obtained from Lenders whose Pro Rata Shares, in the aggregate, are at least eighty-five percent (85%), or (ii) any payments that are requested by a Lender (an “Increased Cost Lender”) pursuant to Section 2.4(i), the Borrower may identify an assignee to which a non-consenting Lender or Increased Cost Lender shall assign its rights and obligations under this Agreement (including, without limitation, its Pro Rata Share of the Commitment and the Advances owing to it) and the other Loan Documents at par value pursuant to an Assignment and Assumption substantially in the form attached as Exhibit A, subject to the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed).

     11.5. Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or be otherwise within the limitations of, another covenant shall not avoid the occurrence of an Event of Default or Unmatured Event of Default if such action is taken or condition exists, and if a particular action or condition is expressly permitted under any covenant, unless expressly limited to such covenant, the fact that it would not be permitted under the general provisions of another covenant shall not constitute an Event of Default or Unmatured Event of Default if such action is taken or condition exists.

     11.6. Notices and Delivery. Except as set forth in Section 2.12 or as otherwise specifically provided herein, any consent, notice or other communication herein required or permitted to be given shall be in writing and may be personally served, telecopied or sent by courier service or United States mail and shall be deemed to have been given when delivered in person or by courier service, upon receipt of a telecopy (or on the next Business Day if such telecopy is received on a non-Business Day or after 5:00 P.M. on a Business Day) or four (4) Business Days after deposit in the United States mail (registered or certified, with postage prepaid and properly addressed). Notices to Administrative Agent pursuant to Article 2 shall not be effective until received by Administrative Agent. For the purposes hereof, the addresses of the parties hereto (until notice of a change thereof is delivered as provided in this Section 11.6) shall be as set forth below each party’s name on the signature pages hereof, or, as to each party, at such other address as may be designated by such party in a written notice to all of the other

Page 101

parties. All deliveries to be made to Administrative Agent for distribution to the Lenders shall be made to Administrative Agent at the address specified for notice on the signature page hereto and in addition, a sufficient number of copies of each such delivery shall be delivered to Administrative Agent for delivery to each Lender at the address specified for deliveries on the signature page hereto or such other address as may be designated by Administrative Agent in a written notice.

     11.7. Survival of Warranties, Indemnities and Agreements. All agreements, representations, warranties and indemnities made or given herein shall survive the execution and delivery of this Agreement and the other Loan Documents and the making and repayment of the Advances hereunder and such indemnities shall survive termination hereof.

     11.8. Failure or Indulgence Not Waiver: Remedies Cumulative. No failure or delay on the part of Administrative Agent or any Lender in the exercise of any power, right or privilege under any of the Loan Documents shall impair such power, right or privilege or be construed to be a waiver of any default or acquiescence therein, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege. All rights and remedies existing under the Loan Documents are cumulative to and not exclusive of any rights or remedies otherwise available.

     11.9. Payments Set Aside. To the extent that Borrower makes a payment or payments to Administrative Agent or the Lenders, or Administrative Agent or the Lenders exercise their rights of setoff, and such payment or payments or payments or the proceeds of such setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then to the extent of such recovery, the Obligation or part thereof originally intended to be satisfied, and all rights and remedies therefor, shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred.

     11.10. Severability. In case any provision in or obligation under this Agreement or the other Loan Documents shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby, provided, however, that if the rates of interest or any other amount payable hereunder, or the collectability thereof, are declared to be or become invalid, illegal or unenforceable, the Lenders’ obligations to make Advances shall not be enforceable.

     11.11. Headings. Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose or be given any substantive effect.

Page 102

     11.12. Governing Law; Waiver. THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA.

     11.13. Limitation of Liability. To the extent permitted by applicable law and other than with respect to gross negligence or willful misconduct, no claim may be made by Borrower, any Lender or any other Person against Administrative Agent or any Lender, or the affiliates, directors, officers, employees, attorneys or agents of any of them, for any special, indirect, consequential or punitive damages in respect of any claim for breach of contract or any other theory of liability arising out of or related to the transactions contemplated by this Agreement, or any act, omission or event occurring in connection therewith; and Borrower and each Lender hereby waive, release and agree not to sue upon any claim for any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

     11.14. Successors and Assigns. This Agreement and the other Loan Documents shall be binding upon the parties hereto and their respective successors and assigns and shall inure to the benefit of the parties hereto and the successors and permitted assigns of Administrative Agent and the Lenders. The terms and provisions of this Agreement shall inure to the benefit of any permitted assignee or transferee of the Advances and the Pro Rata Shares of the Commitment of the Lenders under this Agreement, and in the event of such transfer or assignment, the rights and privileges herein conferred upon Administrative Agent and the Lenders shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions hereof. Borrower’s and the REIT’s rights and interests hereunder and under the other Loan Documents, and Borrower’s and the REIT’s duties and Obligations hereunder and under the other Loan Documents, shall not be assigned or otherwise transferred without the consent of all the Lenders.

     11.15. Consent to Jurisdiction and Service of Process; Waiver of Jury Trial. ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST BORROWER WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE, AND ALL JUDICIAL PROCEEDINGS BROUGHT BY BORROWER WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT SHALL BE, BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION HAVING SITUS WITHIN THE BOUNDARIES OF THE FEDERAL COURT DISTRICT OF THE SOUTHERN DISTRICT OF CALIFORNIA, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, BORROWER ACCEPTS, FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS, AND IRREVOCABLY AGREES TO BE BOUND BY ANY FINAL JUDGMENT RENDERED THEREBY FROM WHICH NO APPEAL HAS BEEN TAKEN OR IS AVAILABLE. BORROWER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO ITS NOTICE ADDRESS SPECIFIED ON THE SIGNATURE PAGES HEREOF. BORROWER, ADMINISTRATIVE AGENT AND THE LENDERS IRREVOCABLY WAIVE (A) TRIAL BY JURY IN ANY ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, AND (B) ANY OBJECTION (INCLUDING WITHOUT LIMITATION, ANY

Page 103

OBJECTION OF THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS) WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY JURISDICTION SET FORTH ABOVE. NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF ADMINISTRATIVE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST BORROWER IN THE COURTS OF ANY OTHER JURISDICTION.

     11.16. Counterparts; Effectiveness; Inconsistencies. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in counterparts, each of which when so executed and delivered shall be deemed an original, but all of which, taken together, shall constitute but one and the same instrument. This Agreement shall become effective when (i) Borrower, the initial Lenders and Administrative Agent have duly executed and delivered signature pages of this Agreement to each other (delivery by Borrower to the Lenders and by any Lender to Borrower and any other Lender being deemed to have been made by delivery to Administrative Agent) and (ii) Administrative Agent has received all fees due under its separate agreement with Borrower. Administrative Agent shall send written confirmation of the Closing Date to Borrower and each other Lender promptly following the occurrence thereof. This Agreement and each of the other Loan Documents shall be construed to the extent reasonable to be consistent one with the other, but to the extent that the terms and conditions of this Agreement are actually and directly inconsistent with the terms and conditions of any other Loan Document, this Agreement shall govern.

     11.17. Performance of Obligations. Borrower agrees that Administrative Agent may, but shall have no obligation to, make any payment or perform any act required of Borrower under any Loan Document which Borrower has failed to make or do.

     11.18. Construction. The parties to this Agreement acknowledge that each party and its counsel have reviewed and revised this Agreement and that the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement or any amendments or exhibits hereto.

     11.19. Entire Agreement. This Agreement, taken together with all of the other Loan Documents and all certificates and other documents delivered by Borrower to Administrative Agent, embodies the entire agreement and supersede all prior agreements, written and oral, relating to the subject matter hereof.

     11.20. Assignments and Participations.

          (a) After first obtaining the approval of Administrative Agent and Borrower (provided that the approval of Borrower shall not be required upon the occurrence and during the continuance of any Event of Default), which approval shall not be unreasonably withheld or delayed, each Lender may assign to one or more banks or financial institutions, all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Pro Rata Share of the Commitment and the Advances owing to it) and the other Loan Documents; provided, however, that (i) each such assignment shall be of a constant, and not a

Page 104

varying, percentage of the assigning Lender’s rights and obligations under this Agreement and the other Loan Documents, and such percentage of the assigning Lender’s rights and obligations shall be the same percentage with respect to both such Lender’s Pro Rata Share of the Commitment and Advances, (ii) the aggregate amount of the Pro Rata Share of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Assumption with respect to such assignment) shall in no event be less than Ten Million Dollars ($10,000,000), (iii) the parties to each such assignment shall execute and deliver to Administrative Agent, for its approval and acceptance, an Assignment and Assumption, (iv) Administrative Agent shall receive from the assignor a processing fee of Three Thousand Dollars ($3,000) and (v) if such assignment is less than all of the Pro Rata Share of the Commitment of the assigning Lender, after giving effect to such assignment, the aggregate amount of the Pro Rata Share of the Commitment of the assigning Lender shall in no event be less than Fifteen Million Dollars ($15,000,000). Without restricting the right of Borrower or Administrative Agent to reasonably object to any bank or financial institution becoming an assignee of an interest of a Lender hereunder, each proposed assignee must be an existing Lender or a bank or financial institution which (A) has (or, in the case of a bank which is a subsidiary, such bank’s parent has) a rating of its senior unsecured debt obligations of not less than Baa-2 by Moody’s Investors Service, Inc. or a comparable rating by a rating agency acceptable to Administrative Agent and (B) has total assets in excess of Ten Billion Dollars ($10,000,000,000). Unless Administrative Agent or Borrower gives written notice to the assigning Lender that it objects to the proposed assignment that otherwise satisfies the requirements of this Section 11.20(a) (together with a written explanation of the reasons behind such objection) within ten (10) Business Days following receipt of the assigning Lender’s written request for approval of the proposed assignment, Administrative Agent or Borrower, as the case may be, shall be deemed to have approved such assignment. Upon such execution, delivery, approval and acceptance, and upon the effective date specified in the applicable Assignment and Assumption, (X) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Assumption, have the rights and obligations of a Lender hereunder, and (Y) the assigning Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Assumption, relinquish its rights and be released from its obligations under this Agreement.

          (b) By executing and delivering an Assignment and Assumption, the assigning Lender thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Assumption, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or any other Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Loan Document or any other instrument or document furnished pursuant hereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the REIT or Borrower or the performance or observance by the REIT or Borrower of any of their respective obligations under any Loan Document or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Article 4 or delivered pursuant to Article 5 to the date of such assignment and such other Loan Documents and other

Page 105

documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Assumption; (iv) such assignee will, independently and without reliance upon Administrative Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee appoints and authorizes Administrative Agent to take such action as Administrative Agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to Administrative Agent by the terms hereof and thereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

          (c) Administrative Agent shall maintain, at its address referred to on the counterpart signature pages hereof, a copy of each Assignment and Assumption delivered to and accepted by it and shall record in the Loan Account the names and addresses of each Lender and the Pro Rata Share of the Commitment of, and principal amount of the Advances owing to, such Lender from time to time. Borrower, Administrative Agent and the Lenders may treat each Person whose name is recorded in the Loan Account as a Lender hereunder for all purposes of this Agreement.

          (d) Upon its receipt of an Assignment and Assumption executed by an assigning Lender and an assignee approved by Administrative Agent and Borrower as provided in Section 11.20(a), Administrative Agent shall, if such Assignment and Assumption has been properly completed and is in substantially the form of Exhibit A, (i) accept such Assignment and Assumption, (ii) record the information contained therein in the Loan Account, and (iii) give prompt notice thereof to Borrower. Upon request, Borrower will execute and deliver to Administrative Agent an appropriate replacement promissory note or replacement promissory notes in favor of each assignee (and assignor, if such assignor is retaining a portion of its Pro Rata Share of the Commitment and Advances) reflecting such assignee’s (and assignor’s) Pro Rata Share of the Commitment. Upon execution and delivery of such replacement promissory note(s) the original promissory note or notes evidencing all or a portion of the Pro Rata Share of the Commitment and Advances being assigned shall be canceled and returned to Borrower.

          (e) Each Lender may sell participations to one or more banks or other entities in or to all or a portion of its rights and obligations under this Agreement without the consent of any other party to this Agreement (including, without limitation, all or a portion of its Pro Rata Share of the Commitment and the Advances owing to it) and the other Loan Documents; provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its obligation to fund its Pro Rata Share of the Commitment to Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participating banks or other financial institutions shall not be a Lender hereunder for any purpose, (iv) Borrower, Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and with regard to any and all payments to be made under this Agreement, (v) the participation interest shall be expressed as a percentage of the granting Lender’s Pro Rata Share of the Commitment as it then exists and shall not restrict an increase in the Commitment, or in the granting Lender’s Pro Rata Share of the Commitment, so

Page 106

long as the amount of the participation interest is not affected thereby and (vi) the consent of the holder of such participation interest shall not be required for amendments or waivers of provisions of the Loan Documents and the holder of any such participation shall not be entitled to voting rights under their participation agreement except for voting rights with respect to (A) extensions of the Maturity Date beyond the extension option term; and (B) decreases in the interest rates or fees described in this Agreement.

          (f) Borrower will use reasonable efforts to cooperate with Administrative Agent and the Lenders in connection with the assignment of interests under this Agreement or the sale of participations herein.

          (g) Notwithstanding anything in this Agreement to the contrary, and without the need to comply with any of the formal or procedural requirements of this Agreement, including Section 11.20, any Lender may at any time and from time to time pledge and assign all or any portion of its rights under all or any of the Loan Documents to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from its obligations thereunder.

          (h) Notwithstanding anything in this Agreement to the contrary, any Lender may assign all or any portion of its rights and obligations under this Agreement to another branch or Affiliate of such Lender without first obtaining the approval of Administrative Agent and Borrower, provided that (i) at the time of such assignment such Lender is not a Defaulting Lender, (ii) such Lender gives Administrative Agent and Borrower at least fifteen (15) days’ prior written notice of any such assignment, (iii) the parties to each such assignment execute and deliver to Administrative Agent an Assignment and Assumption, and (iv) Administrative Agent receives from assignor a processing fee of Three Thousand Dollars ($3,000).

          (i) No Lender shall be permitted to assign or sell all or any portion of its rights and obligations under this Agreement to Borrower or any Affiliate of Borrower.

          (j) The dissemination or disclosure by any Lender to any prospective assignee or participant of any confidential information obtained by Administrative Agent or the Lenders pursuant to this Agreement or in connection with the Advances is subject to the terms of Section 5.3.

          (k) Wells Fargo agrees that, so long as Well Fargo is the Administrative Agent under this Agreement, it will not assign all or any portion of its rights and obligations under this Agreement if, after giving effect to such assignment or sale, Wells Fargo’s Pro Rata Share of the Commitment would be less than that of the Lender with the next largest Pro Rata Share of the Commitment, provided, however, that in no event shall Wells Fargo be required to increase its Pro Rata Share above that which exists on the Closing Date.

     11.21. Tax Shelter Regulations. Neither Borrower, any guarantor, any non-borrower trustor, nor any subsidiary of any of the foregoing intends to treat or has treated the Loan or transactions contemplated by this Agreement and the other Loan Documents as being a “reportable transaction” (within the meaning of Treasury Regulation Section 1.6011-4). If Borrower or any other party to the Loan determines to take, or has otherwise taken, any action inconsistent with such intention, Borrower will promptly notify the Lenders thereof. If the

Page 107

Borrower so notifies the Lenders, Borrower acknowledges that Lenders may treat the Loan as part of a transaction that is subject to Treasury Regulation Section  ###-###-####-1, and such Lenders will maintain the lists and other records, including the identity of the applicable party to the Loan as required by such Treasury Regulation.

FORM OF BID ADVANCE NOTE

     FOR VALUE RECEIVED, ARDEN REALTY LIMITED PARTNERSHIP, a Maryland limited partnership (“Borrower”), HEREBY PROMISES TO PAY to the order of ______ (“Lender”) the principal sum of ______ DOLLARS ($______) or if less, the aggregate unpaid principal amount of all “Bid Advances” disbursed by Lender under that certain Fourth Amended and Restated Revolving Credit Agreement dated as of July ___, 2005 (as amended, supplemented or modified from time to time, the “Credit Agreement”) entered into among Borrower, the Lenders named therein, Wells Fargo Bank, National Association, as Administrative Agent and Sole Lead Arranger, Deutsche Bank Trust Company Americas, Wachovia Bank, N.A., and JPMorgan Chase Bank, N.A., as Syndication Agents, and PNC Bank, National Association, as Documentation Agent, together with interest on the unpaid principal balance hereof at the rate (or rates) determined in accordance with Section 2.4 of the Credit Agreement from the date such principal is advanced until it is paid in full. It is contemplated that there will be advances and payments under this Bid Advance Note from time to time, but no advances or payments under this Bid Advance Note (including payment in full of the unpaid balance of principal hereof prior to maturity) shall affect or impair the validity or enforceability of this Bid Advance Note as to future advances hereunder.

     This Bid Advance Note is one of the Notes referred to in and governed by the Credit Agreement, which Credit Agreement, among other things, contains provisions for the acceleration of the maturity hereof and for the payment of certain additional sums to Lender upon the happening of certain stated events. Capitalized terms used in this Bid Advance Note without definition have the same meanings as in the Credit Agreement.

     The principal amount of this Bid Advance Note, if not sooner paid as required pursuant to the Credit Agreement, will be due and payable, together with all accrued and unpaid interest and other amounts due and unpaid under the Credit Agreement, on the Maturity Date. Except as provided in Section 2.1(a)(ii)(A)(3), Borrower may not make any voluntary prepayments of all or a portion of this Bid Advance Note.

     Interest on Absolute Rate Bid Advances is payable in arrears on the first Business Day of each month during the respective Fixed Rate Periods relating to the Bid Advances evidenced hereby, commencing with the first Business Day of the first calendar month to begin after the date of this Bid Advance Note. Interest on Fixed Rate Bid Advances shall be payable in arrears at the end of each Interest Period applicable to such Bid Advance, but in no event less frequently than once every three months with respect to such Interest Period. Interest will be computed on the basis of the actual number of days elapsed in the period during which interest accrues and a year of three hundred sixty (360) days. The Credit Agreement provides for the payment by Borrower of various other charges and fees, in addition to the interest charges described in the Credit Agreement, as set forth more fully in the Credit Agreement.

Page 1 of 3

     All payments of any amount becoming due under this Bid Advance Note shall be made in the manner provided in the Credit Agreement, in Dollars.

     Upon and after the occurrence of an Event of Default, unless such Event of Default is waived as provided in the Credit Agreement, this Bid Advance Note may, at the option of Requisite Lenders and without demand, notice or legal process of any kind, be declared by Administrative Agent, and in such case immediately shall become, due and payable. Upon and after the occurrence of certain Events of Default, this Bid Advance Note shall, as provided in the Credit Agreement, without any action by Lenders and without demand, notice or legal process of any kind, automatically and immediately become due and payable.

     Demand, presentment, protest and notice of nonpayment and protest, notice of intention to accelerate maturity, notice of acceleration of maturity and notice of dishonor are hereby waived by Borrower. Subject to the terms of the Credit Agreement, including but not limited to, Section 11.4 of the Credit Agreement, Lender may extend the time of payment of this Bid Advance Note, postpone the enforcement hereof, grant any indulgences, release any party primarily or secondarily liable hereon or agree to any subordination of Borrower’s obligations hereunder without affecting or diminishing such Lender’s right of recourse against Borrower, which right is hereby expressly reserved.

     This Bid Advance Note has been delivered and accepted at Los Angeles, California. This Bid Advance Note shall be interpreted in accordance with, and the rights and liabilities of the parties hereto shall be determined and governed by, the laws of the State of California.

     In no contingency or event whatsoever shall interest charged in respect of the Advances evidenced hereby, however such interest may be characterized or computed, exceed the highest rate permissible under any law that a court of competent jurisdiction shall, in a final determination, deem applicable hereto. If such a court determines that Lender has received interest hereunder in excess of the highest rate applicable hereto, Lender shall, at Lender’s election, either (a) promptly refund such excess interest to Borrower or (b) credit such excess to the principal balance of the outstanding Advances held by that Lender. This provision shall control over every other provision of all agreements between Borrower and Lender.

Page 2 of 3

     Whenever possible each provision of this Bid Advance Note shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Bid Advance Note shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Bid Advance Note.
