Borrowings are classified for purposes of this Agreement either by reference to the pricing of Loans comprising such Borrowing (e.g., a “Fixed Rate Borrowing” is a Euro-Dollar Borrowing or a Money Market Borrowing (excluding any such Borrowing consisting of Money Market LIBOR Loans bearing interest at the Base Rate pursuant to Article VIII), and a “Euro-Dollar Borrowing” is a Borrowing comprised of Euro-Dollar Loans) or by reference to the provisions of Article II under which participation therein is determined (i.e., a “Committed Borrowing” is a Borrowing under Section 2.1 in which all Banks participate in proportion to their Commitments, while a “Money Market Borrowing” is a Borrowing under Section 2.3 in which a Bank’s share is determined on the basis of its bid in accordance therewith, and a “Swingline Borrowing” is a Borrowing under Section 2.16 in which only the Swingline Lender participates (subject to the provisions of said Section 2.16)).

ARTICLE II

THE CREDITS

SECTION 2.1 Commitments to Lend. Each Bank severally agrees, on the terms and conditions set forth in this Agreement, to make Committed Loans to the Borrower pursuant to this Article from time to time during the term hereof in amounts such that the aggregate principal amount of Committed Loans plus such Bank’s Pro Rata Share of Swingline Loans by such Bank at any one time outstanding shall not exceed the amount of its Commitment. Each Borrowing outstanding under this Section 2.1 shall be in an aggregate principal amount of $3,000,000, or an integral multiple of $100,000 in excess thereof (except that any such Borrowing may be in the aggregate amount available in accordance with Section 3.2(b), or in any amount required to repay the Swingline Lender the amount of any Swingline Loan) and, other than with respect to Money Market Loans and Swingline Loans, shall be made from the several Banks

ratably in proportion to their respective Commitments. In no event shall the aggregate Loans outstanding at any time exceed $500,000,000, as the same may be reduced from time to time as a result of cancellation of Commitments by Borrower or pursuant to Section 2.10 hereof. Subject to the limitations set forth herein, any amounts repaid may be reborrowed.

SECTION 2.2 Notice of Borrowing. The Borrower shall give Administrative Agent notice not later than 11:30 a.m. (New York time) (x) one Domestic Business Day before each Base Rate Borrowing, or (y) three Euro-Dollar Business Days before each Euro-Dollar Borrowing, specifying:

(i) the date of such Borrowing, which shall be a Domestic Business Day in the case of a Base Rate Borrowing or a Euro-Dollar Business Day in the case of a Euro-Dollar Borrowing,

(ii) the aggregate amount of such Borrowing,

(iii) whether the Loans comprising such Borrowing are to be Base Rate Loans or Euro-Dollar Loans, and

(iv) in the case of a Euro-Dollar Borrowing, the duration of the Interest Period applicable thereto, subject to the provisions of the definition of Interest Period.

SECTION 2.3 Money Market Borrowings.

(a) The Money Market Option. From time to time during the Term, and provided that at such time the Borrower maintains an Investment Grade Rating from both S&P and Xxxxx’x, the Borrower may, as set forth in this Section 2.3, request the Banks during the Term to make offers to make Money Market Loans to the Borrower, not to exceed, at such time, the lesser of (i) fifty percent (50%) of the aggregate Commitments, and (ii) the aggregate Commitments less all Loans then outstanding. Subject to the provisions of this Agreement, the Borrower may repay any outstanding Money Market Loan on any day which is a Euro-Dollar Business Day and any amounts so repaid may be reborrowed, up to the amount available under this Section 2.3 at the time of such Borrowing, until the Domestic Business Day next preceding the Maturity Date. The Banks may, but shall have no obligation to, make such offers and the Borrower may, but

shall have no obligation to, accept any such offers in the manner set forth in this Section 2.3.

(b) Money Market Quote Request. When the Borrower wishes to request offers to make Money Market Loans under this Section, it shall transmit to the Administrative Agent by facsimile transmission a request substantially in the form of Exhibit B hereto (a “Money Market Quote Request”) so as to be received not later than 10:30 A.M. (New York time) on (x) the fourth Euro-Dollar Business Day prior to the date of Borrowing proposed therein, in the case of a LIBOR Auction or (y) the Domestic Business Day next preceding the date of Borrowing proposed therein, in the case of an Absolute Rate Auction (or, in either case, such other time or date as the Borrower and the Administrative Agent shall have mutually agreed and shall have notified to the Banks not later than the date of the Money Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for which such change is to be effective) specifying:

1. the proposed date of Borrowing, which shall be a Euro-Dollar Business Day in the case of a LIBOR Auction or a Domestic Business Day in the case of an Absolute Rate Auction,

2. the aggregate amount of such Borrowing, which shall be $3,000,000 or a larger multiple of $100,000,

3. the duration of the Interest Period applicable thereto (which shall not be less than 7 days or more than 90 days), subject to the provisions of the definition of Interest Period, and

4. whether the Money Market Quotes requested are to set forth a Money Market Margin or a Money Market Absolute Rate.

The Borrower may request offers to make Money Market Loans for more than one Interest Period in a single Money Market Quote Request. No Money Market Quote Request shall be given within four Euro-Dollar Business Days (or such other number of days as the Borrower and the Administrative Agent may agree) of any other Money Market Quote Request. Together with the delivery of each Money Market Quote Request, Borrower shall pay to the Administrative Agent, a fee equal to $2,500.

(c) Invitation for Money Market Quotes. Promptly upon receipt of a Money Market Quote Request, the Administrative Agent shall send to the Banks by facsimile or electronic transmission a copy thereof, which shall constitute an invitation by the Borrower to each Bank to submit Money Market Quotes offering to make the Money Market Loans to which such Money Market Quote Request relates in accordance with this Section (an “Invitation for Money Market Quotes”).

(d) Submission and Contents of Money Market Quotes.

1. Each Bank may submit a Money Market Quote containing an offer or offers to make Money Market Loans in response to any Invitation for Money Market Quotes. Each Money Market Quote must comply with the requirements of this subsection (d) and must be submitted to the Administrative Agent by facsimile transmission at its offices specified in or pursuant to Section 9.1 not later than (x) 10:00 A.M. (New York time) on the third Euro-Dollar Business Day prior to the proposed date of Borrowing, in the case of a LIBOR Auction or (y) 9:30 A.M. (New York time) on the proposed date of Borrowing, in the case of an Absolute Rate Auction (or, in either case, such other time or date as the Borrower and the Administrative Agent shall have mutually agreed and shall have notified to the Banks not later than the date of the Money Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for which such change is to be effective); provided that Money Market Quotes submitted by the Bank serving as the Administrative Agent (or any affiliate of the Bank serving as the Administrative Agent) in the capacity of a Bank may be submitted, and may only be submitted, if the Bank serving as the Administrative Agent or such affiliate notifies the Borrower of the terms of the offer or offers contained therein not later than (x) one hour prior to the deadline for the other Banks, in the case of a LIBOR Auction or (y) 15 minutes prior to the deadline for the other Banks, in the case of an Absolute Rate Auction. Subject to Articles III and VI, any Money Market Quote so made shall be irrevocable except with the written consent of the Administrative Agent given on the instructions of the Borrower. Such Money Market Loans may be funded by such Bank’s Designated Lender (if any) as provided in Section 9.6(d), however, such Bank shall not be required to specify in its Money Market Quote whether such Money Market Loans will be funded by such Designated Lender.

2. Each Money Market Quote shall be in substantially the form of Exhibit D hereto and shall in any case specify:

(a) the proposed date of Borrowing,

(b) the principal amount of the Money Market Loan for which each such offer is being made, which principal amount (w) may be greater than or less than the Commitment of the quoting Bank, (x) must be $3,000,000 or a larger multiple of $100,000, (y) may not exceed the principal amount of Money Market Loans for which offers were requested and (z) may be subject to an aggregate limitation as to the principal amount of Money Market Loans for which offers being made by such quoting Bank may be accepted,

(c) in the case of a LIBOR Auction, the margin above or below the applicable Euro-Dollar Rate (the “Money Market Margin”) offered for each such Money Market Loan, expressed as a percentage (specified to the nearest 1/10,000th of 1%) to be added to or subtracted from such base rate,

(d) in the case of an Absolute Rate Auction, the rate of interest per annum (specified to the nearest 1/10,000th of 1%) (the “Money Market Absolute Rate”) offered for each such Money Market Loan, and

(e) the identity of the quoting Bank.

A Money Market Quote may set forth up to five separate offers by the quoting Bank with respect to each Interest Period specified in the related Invitation for Money Market Quotes.

3. Any Money Market Quote shall be disregarded if it:

(a) is not substantially in conformity with Exhibit D hereto or does not specify all of the information required by subsection (d)(2) above;

(b) contains qualifying, conditional or similar language (except for an aggregate limitation as provided in subsection (d)(2)(b) above);

(c) proposes terms other than or in addition to those set forth in the applicable Invitation for Money Market Quotes(except for an aggregate limitation as provided in subsection (d)(2) above); or

(d) arrives after the time set forth in subsection (d)(1).

(e) Notice to Borrower. The Administrative Agent shall promptly (and in any event no later than 10:30 A.M. (New York time) on the third Euro-Dollar Business Day prior to the date of the proposed Borrowing) notify the Borrower in writing of the terms (x) of any Money Market Quote submitted by a Bank that is in accordance with subsection (d) and (y) of any Money Market Quote that amends, modifies or is otherwise inconsistent with a previous Money Market Quote submitted by such Bank with respect to the same Money Market Quote Request. Any such subsequent Money Market Quote shall be disregarded by the Administrative Agent unless such subsequent Money Market Quote is submitted solely to correct a manifest error in such former Money Market Quote or modifies the terms of such previous Money Market Quote to provide terms more favorable to Borrower. The Administrative Agent’s notice to the Borrower shall specify (A) the aggregate principal amount of Money Market Loans for which offers have been received for each Interest Period specified in the related Money Market Quote Request, (B) the respective principal amounts and Money Market Margins or Money Market Absolute Rates, as the case may be, so offered and (C) if applicable, limitations on the aggregate principal amount of Money Market Loans for which offers in any single Money Market Quote may be accepted.

(f) Acceptance and Notice by Borrower. Not later than 11:00 A.M. (New York time) on (x) the third Euro-Dollar Business Day prior to the proposed date of Borrowing, in the case of a LIBOR Auction or (y) the proposed date of Borrowing, in the case of an Absolute Rate Auction (or, in either case, such other time or date as the Borrower and the Administrative Agent shall have mutually agreed and shall have notified to the Banks not later than the date of the Money Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for which such change is to be effective), the Borrower shall notify the Administrative Agent of its acceptance or non-acceptance of the offers so notified to it pursuant to subsection (e). In the case of acceptance, such notice (a “Notice of Money Market Borrowing”) shall specify the aggregate principal amount of offers for each Interest Period that are accepted. The

Borrower may accept any Money Market Quote in whole or in part; provided that:

1. the aggregate principal amount of each Money Market Borrowing may not exceed the applicable amount set forth in the related Money Market Quote Request;

2. the principal amount of each Money Market Borrowing must be $3,000,000 or a larger multiple of $100,000;

3. acceptance of offers may only be made on the basis of ascending Money Market Margins or Money Market Absolute Rates, as the case may be; and

4. the Borrower may not accept any offer that is described in subsection (d)(3) or that otherwise fails to comply with the requirements of this Agreement.

(g) Allocation by Administrative Agent. If offers are made by two or more Banks with the same Money Market Margins or Money Market Absolute Rates, as the case may be, for a greater aggregate principal amount than the amount in respect of which such offers are permitted to be accepted for the related Interest Period, the principal amount of Money Market Loans in respect of which such offers are accepted shall be allocated by the Administrative Agent among such Banks as nearly as possible (in multiples of $100,000, as the Administrative Agent may deem appropriate) in proportion to the aggregate principal amounts of such offers. The Administrative Agent shall promptly (and in any event within one (1) Domestic Business Day after such offers are accepted) notify the Borrower and each such Bank in writing of any such allocation of Money Market Loans. Determinations by the Administrative Agent of the allocation of Money Market Loans shall be conclusive in the absence of manifest error.

(h) Notification by Administrative Agent. Upon receipt of the Borrower’s Notice of Money Market Borrowing in accordance with Section 2.3(f) hereof, the Administrative Agent shall, on the date such Notice of Money Market Borrowing is received by the Administrative Agent, promptly notify each Bank (and such Notice of Money Market Borrowing shall not thereafter be revocable by the Borrower) (i) of the principal amount of the Money Market Borrowing accepted by the Borrower, and (ii) of such Bank’s share (if any) of such Money Market Borrowing. A Bank who is notified that it

has been selected to make a Money Market Loan may designate its Designated Lender (if any) to fund such Money Market Loan on its behalf, as described in Section 9.6(d). Any Designated Lender which funds a Money Market Loan shall on and after the time of such funding become the obligee under such Money Market Loan and be entitled to receive payment thereof when due. No Bank shall be relieved of its obligation to fund a Money Market Loan, and no Designated Lender shall assume such obligation, prior to the time the applicable Money Market Loan is funded.

(i) Funding of Committed Loans Not Affected. Notwithstanding anything to the contrary contained herein, each Bank shall be required to fund its Pro Rata Share of Committed Loans in accordance with Section 2.1 hereof despite the fact that any Bank’s Commitment may have been or may be exceeded as a result of such Bank’s making of Money Market Loans.

SECTION 2.4 Notice to Banks; Funding of Loans.

(a) Upon receipt of a Notice of Borrowing from Borrower in accordance with Section 2.2 hereof, the Administrative Agent shall, on the date such Notice of Borrowing is received by the Administrative Agent, promptly notify each Bank of the contents thereof and of such Bank’s share of such Borrowing, of the interest rate determined pursuant thereto and the Interest Period(s) (if different from those requested by the Borrower) and such Notice of Borrowing shall not thereafter be revocable by the Borrower, unless Borrower shall pay any applicable expenses pursuant to Section 2.13.

(b) Not later than 1:00 p.m. (New York time) on the date of each Borrowing as indicated in the Notice of Borrowing, each Bank shall (except as provided in subsection (c) of this Section) make available its share of such Borrowing in Federal funds immediately available in New York, to the Administrative Agent at its address referred to in Section 9.1.

(c) Not later than 3:00 p.m. (New York time) on the date of each Swingline Borrowing as indicated in the applicable Notice of Borrowing, the Swingline Lender shall make available such Swingline Borrowing in Federal funds immediately available in New York, NY, to the Administrative Agent at its address referred to herein.

(d) Unless the Administrative Agent shall have received notice from a Bank prior to the date of any Borrowing that such Bank will not make available to the Administrative Agent such Bank’s share of such Borrowing, the Administrative Agent may assume that such Bank has made such share available to the Administrative Agent on the date of such Borrowing in accordance with subsection (b) of this Section 2.4 and the Administrative Agent may, in reliance upon such assumption, but shall not be obligated to, make available to the Borrower on such date a corresponding amount on behalf of such Bank. If and to the extent that such Bank shall not have so made such share available to the Administrative Agent, such Bank and the Borrower severally agree to repay to the Administrative Agent forthwith on demand, and in the case of the Borrower one (1) Domestic Business Day after demand, such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, a rate per annum equal to the interest rate applicable thereto pursuant to Section 2.7 and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Bank’s Loan included in such Borrowing as of the date of such Borrowing for purposes of this Agreement.

SECTION 2.5 Notes.

(a) The Loans of each Bank shall be evidenced by a single Note payable to the order of such Bank for the account of its Applicable Lending Office.

(b) Each Bank may, by notice to the Borrower and the Administrative Agent, request that its Loans of a particular type (including Swingline Loans and Money Market Loans) be evidenced by a separate Note in an amount equal to the aggregate unpaid principal amount of such Loans. Any additional costs incurred by the Administrative Agent, the Borrower or the Banks in connection with preparing such a Note shall be at the sole cost and expense of the Bank requesting such Note. In the event any Loans evidenced by such a Note are paid in full prior to the Maturity Date, any such Bank shall return such Note to Borrower. Each such Note shall be in substantially the form of Exhibit A-2 hereto with appropriate modifications to reflect the fact that it evidences solely Loans of the relevant type. Upon the execution and delivery of any such Note, any existing

Note payable to such Bank shall be replaced or modified accordingly. Each reference in this Agreement to the “Note” of such Bank shall be deemed to refer to and include any or all of such Notes, as the context may require.

(c) Upon receipt of each Bank’s Note pursuant to Section 3.1(a), the Administrative Agent shall forward such Note to such Bank. Each Bank shall record the date, amount, type and maturity of each Loan made by it and the date and amount of each payment of principal made by the Borrower with respect thereto, and may, if such Bank so elects in connection with any transfer or enforcement of its Note, endorse on the appropriate schedule appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that the failure of any Bank to make any such recordation or endorsement shall not affect the obligations of the Borrower hereunder or under the Notes. Each Bank is hereby irrevocably authorized by the Borrower so to endorse its Note and to attach to and make a part of its Note a continuation of any such schedule as and when required.

(d) The Committed Loans shall mature, and the principal amount thereof shall be due and payable, on the Maturity Date. The Swingline Loans shall mature, and the principal amount thereof shall be due and payable, in accordance with Section 2.16(b)(iii).

(e) Each Money Market Loan included in any Money Market Borrowing shall mature, and the principal amount thereof shall be due and payable, together with accrued interest thereon, on the earlier to occur of (i) last day of the Interest Period applicable to such Borrowing or (ii) the Maturity Date.

(f) There shall be no more than ten (10) Euro-Dollar Groups of Loans outstanding at any one time.

SECTION 2.6 Method of Electing Interest Rates.

(a) The Loans included in each Committed Borrowing shall bear interest initially at the type of rate specified by the Borrower in the applicable Notice of Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Group of Loans (subject in each case to the provisions of Article VIII), as follows:

(i) if such Loans are Base Rate Loans, the Borrower may elect to convert all or any portion of such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day;

(ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to convert all or any portion of such Loans to Base Rate Loans and/or elect to continue all or any portion of such Loans as Euro-Dollar Loans for an additional Interest Period or additional Interest Periods, in each case effective on the last day of the then current Interest Period applicable to such Loans, or on such other date designated by Borrower in the Notice of Interest Rate Election provided Borrower shall pay any losses pursuant to Section 2.13.

Each such election shall be made by delivering a notice (a “Notice of Interest Rate Election”) to the Administrative Agent at least three (3) Euro-Dollar Business Days before the conversion or continuation selected in such notice is to be effective. A Notice of Interest Rate Election may, if it so specifies, apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group of Loans, (ii) the portion to which such Notice of Interest Rate Election applies, and the remaining portion to which it does not apply, are each $500,000 or any larger multiple of $100,000, (iii) there shall be no more than ten (10) Euro-Dollar Groups of Loans outstanding at any time, (iv) no Committed Loan may be continued as, or converted into, a Euro-Dollar Loan when any Event of Default has occurred and is continuing, and (v) no Interest Period shall extend beyond the Maturity Date.

(b) Each Notice of Interest Rate Election shall specify:

(i) the Group of Loans (or portion thereof) to which such notice applies;

(ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable clause of subsection (a) above;

(iii) if the Loans comprising such Group of Loans are to be converted, the new type of Loans and, if

such new Loans are Euro-Dollar Loans, the duration of the initial Interest Period applicable thereto; and

(iv) if such Loans are to be continued as Euro-Dollar Loans for an additional Interest Period, the duration of such additional Interest Period.

Each Interest Period specified in a Notice of Interest Rate Election shall comply with the provisions of the definition of Interest Period.

(c) Upon receipt of a Notice of Interest Rate Election from the Borrower pursuant to subsection (a) above, the Administrative Agent shall notify each Bank the same day as it receives such Notice of Interest Rate Election of the contents thereof, the interest rates determined pursuant thereto and the Interest Periods (if different from those requested by the Borrower) and such notice shall not thereafter be revocable by the Borrower. If the Borrower fails to deliver a timely Notice of Interest Rate Election to the Administrative Agent for any Group of Loans which are Euro-Dollar Loans, such Loans shall be converted into Base Rate Loans on the last day of the then current Interest Period applicable thereto.

(d) If the Borrower shall fail to pay any principal of or interest on any Money Market Loan when due, such Money Market Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Base Rate until (in the case of a failure to pay interest) such failure shall become an Event of Default and thereafter (or immediately in the case of a failure to pay principal) at a rate per annum equal to the sum of 4% plus the Base Rate for such day.

SECTION 2.7 Interest Rates.

(a) Each Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the date such Loan is made until the date it is repaid or converted into a Euro-Dollar Loan pursuant to Section 2.6 or at the Maturity Date, at a rate per annum equal to the Base Rate plus the Applicable Margin for Base Rate Loans for such day. Such interest shall be payable on the first Domestic Business Day of each month.

(b) Subject to Section 8.1, each Euro-Dollar Loan shall bear interest on the outstanding principal amount

thereof, for each day during the Interest Period applicable thereto, at a rate per annum equal to the sum of the Applicable Margin for Euro-Dollar Loans for such day plus the Euro-Dollar Rate applicable to such Interest Period. Such interest shall be payable on the last day of each Interest Period or on the first Domestic Business Day of each month, if sooner, as well as on the date of any prepayment of any such Euro-Dollar Loan.

(c) Subject to Section 8.1, each Money Market LIBOR Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the sum of the Euro-Dollar Rate for such Interest Period (determined in accordance with Section 2.7(b) as if the related Money Market LIBOR Borrowing were a Euro-Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the Bank making such Loan in accordance with Section 2.3. Each Money Market Absolute Rate Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the Money Market Absolute Rate quoted by the Bank making such Loan in accordance with Section 2.3. Such interest shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than one month, at intervals of one month after the first day thereof. Any overdue principal of or interest on any Money Market Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Base Rate until (in the case of a failure to pay interest) such failure shall become an Event of Default and thereafter (or immediately in the case of the failure to pay principal) at a rate per annum equal to the sum of 4% plus the Base Rate for such day.

(d) In the event that, and for so long as, any Event of Default shall have occurred and be continuing, the outstanding principal amount of the Loans, and, to the extent permitted by applicable law, overdue interest in respect of all Loans, shall bear interest at the annual rate equal to the sum of the Base Rate and four percent (4%) (the “Default Rate”).

(e) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder. The Administrative Agent shall give prompt notice to the Borrower and the Banks of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of demonstrable error.

SECTION 2.8 Fees.

(a) Unused Fee. If at any time from and after July 13, 2006 and on or prior to December 15, 2006, Borrower shall fail to maintain an average outstanding balance of Loans of not less than $100,000,000, then the Borrower shall pay to the Administrative Agent for the account of the Banks ratably in proportion to their respective Commitments an unused fee (the “Unused Fee”) equal to 0.45% per annum of the amount by which the average outstanding Loans during such period are less than $100,000,000. The Unused Fee shall be payable, in arrears, on September 30, 2006 and December 31, 2006 or on the Maturity Date, if sooner.

(b) Facility Fee. Commencing as of December 16, 2006, the Borrower shall pay to the Administrative Agent for the account of the Banks ratably in proportion to their respective Commitments a facility fee (the “Facility Fee”) equal to 0.15% per annum on the aggregate Commitments. The facility fee shall be payable in arrears on September 30, December 31, March 31, and June 30 during the Term, and on the Maturity Date.

(c) Fees Non-Refundable. All fees set forth in this Section 2.8 shall be deemed to have been earned on the date payment is due in accordance with the provisions hereof and shall be non-refundable. The obligation of the Borrower to pay such fees in accordance with the provisions hereof shall be binding upon the Borrower and shall inure to the benefit of the Administrative Agent and the Banks regardless of whether any Loans are actually made.

SECTION 2.9 Maturity Date. The term (the “Term”) of the Commitments (and each Bank’s obligations to make Loans) shall terminate and expire on the Maturity Date. Upon the date of the termination of the Term, any Loans then outstanding (together with accrued interest thereon and all other Obligations) shall be due and payable on such date.

SECTION 2.10 Mandatory Prepayment. If at any time the Revolving Credit Agreement, dated as of April 1, 2005, among the Borrower, the Administrative Agent and the banks party thereto shall be amended or amended and restated or replaced so as to increase the aggregate commitments thereunder, Borrower shall pay to the Administrative Agent, for the account of the Banks, on or before the earlier to occur of (x) thirty (30) days after the date of such amendment

or replacement, and (y) the end of any Interest Period occurring after such amendment or replacement (but only to the extent of the Loans maturing at the end of any such Interest Period), an amount equal to the increase in the aggregate commitments thereunder (but in no event more than the outstanding balance of the Loans). Borrower shall make such prepayment together with interest accrued to the date of the prepayment on the principal amount prepaid. In connection with the prepayment of a Euro-Dollar Loan prior to the maturity thereof, the Borrower shall also pay any applicable expenses pursuant to Section 2.13. Each such prepayment shall be applied to prepay ratably the Loans of the Banks. Amounts prepaid pursuant to this Section 2.10 may not be reborrowed and the Commitments shall be deemed to have been reduced accordingly.

SECTION 2.11 Optional Prepayments and Optional Decreases and Termination.

(a) The Borrower may, upon at least one (1) Domestic Business Day’s notice to the Administrative Agent (which shall promptly notify each of the Banks), prepay any Group of Loans which are Base Rate Loans(or any Money Market Borrowing bearing interest at the Base Rate pursuant to Section 8.1), in whole at any time, or from time to time in part in amounts aggregating One Million Dollars ($1,000,000) or any larger multiple of One Hundred Thousand Dollars ($100,000), by paying the principal amount to be prepaid. The Borrower may, from time to time on any Domestic Business Day so long as prior notice is given to the Administrative Agent and Swingline Lender no later than 2:00 p.m. (New York time) on the day on which Borrower intends to make such prepayment, prepay any Swingline Loans in whole or in part in amounts aggregating $100,000 or a higher integral multiple of $100,000 (or, if less, the aggregate outstanding principal amount of all Swingline Loans then outstanding) by paying the principal amount to be prepaid no later than 3:00 p.m. (New York time) on such day. Each such optional prepayment shall be applied to prepay ratably the Loans of the several Banks included in such Group of Loans or Borrowing(or the Swingline Lender in the case of Swingline Loans) included in such Group of Loans or Borrowing.

(b) The Borrower may, upon at least one (1) Euro-Dollar Business Day’s notice to the Administrative Agent (which shall promptly notify each of the Banks), prepay any Euro-Dollar Loan as of the last day of the Interest Period

applicable thereto. Except as provided in Article VIII and except with respect to any Euro-Dollar Loan which has been converted to a Base Rate Loan pursuant to Section 8.2, 8.3 or 8.4 hereof, the Borrower may not prepay all or any portion of the principal amount of any Euro-Dollar Loan prior to the end of the Interest Period applicable thereto unless the Borrower shall also pay any applicable expenses pursuant to Section 2.13. Any such prepayment shall be upon at least three (3) Euro-Dollar Business Days’ notice to the Administrative Agent. Each such optional prepayment shall be in the amounts set forth in Section 2.11(a) above and shall be applied to prepay ratably the Loans of the Banks included in any Group of Loans which are Euro-Dollar Loans, except that any Euro-Dollar Loan which has been converted to a Base Rate Loan pursuant to Section 8.2, 8.3 or 8.4 hereof may be prepaid without ratable payment of the other Loans in such Group of Loans which have not been so converted.

(d) Intentionally Omitted.

(e) The Borrower may at any time and from time to time cancel all or any part of the Commitments. If there are Loans then outstanding or, if there are no Loans outstanding at such time as to which the Commitments with respect thereto are being cancelled, upon at least one (1) Domestic Business Day’s notice to the Administrative Agent (which shall promptly notify each of the Banks), whereupon, in either event, all or such portion of the Commitments, as applicable, shall terminate as to the Banks, pro rata on the date set forth in such notice of cancellation, and, if there are any Loans then outstanding, Borrower shall prepay, as applicable, all or such portion of Loans outstanding on such date in accordance with the requirements of Section 2.11(a) and (b). Borrower shall be permitted to designate in its notice of cancellation which Loans, if any, are to be prepaid. A reduction of the Commitments pursuant to this Section 2.11(e) shall not effect a reduction in the Swingline Commitment (unless so elected by the Borrower) until the aggregate Commitments have been reduced to an amount equal to or less than the Swingline Commitment.

(f) Any amounts so prepaid pursuant to Section 2.11 (a), (b), (c) or (d) may be reborrowed. In the event Borrower elects to cancel all or any portion of the Commitments and the Swingline Commitment pursuant to Section 2.11(e) hereof, such amounts may not be reborrowed.

(g) The Borrower may not prepay any portion of a Money Market Loan except with the prior consent of the Bank or Designated Lender holding such Money Market Loan.

SECTION 2.12 General Provisions as to Payments.

(a) The Borrower shall make each payment of interest on the Loans and of fees hereunder, not later than 1:00 p.m. (New York time) on the date when due, in Federal or other funds immediately available in New York, to the Administrative Agent at its address referred to in Section 9.1. The Administrative Agent will promptly (and if received prior to 1:00 p.m., on the same Domestic Business Day, if received after 1:00 p.m. on the immediately following Domestic Business Day) distribute to each Bank its ratable share (or applicable share with respect to Money Market Loans) of each such payment received by the Administrative Agent for the account of the Banks. If and to the extent that the Administrative Agent shall receive any such payment for the account of the Banks on or before 1:00 p.m. (New York time) on any Domestic Business Day, and Administrative Agent shall not have distributed to any Bank its applicable share of such payment on such Domestic Business Day, Administrative Agent shall distribute such amount to such Bank together with interest thereon, for each day from the date such amount should have been distributed to such Bank until the date Administrative Agent distributes such amount to such Bank, at the Federal Funds Rate. Whenever any payment of principal of, or interest on the Base Rate Loans or Swingline Loans or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. Whenever any payment of principal of, or interest on, the Money Market Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time.

(b) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Borrower shall not have so made such payment, each Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Administrative Agent, at the Federal Funds Rate.

SECTION 2.13 Funding Losses. If the Borrower makes any payment of principal with respect to any Euro-Dollar Loan or Money Market LIBOR Loan or Money Market Absolute Rate Loan (pursuant to Article II, VI or VIII or otherwise) on any day other than the last day of the Interest Period applicable thereto, or if the Borrower fails to borrow, continue or convert to any Euro-Dollar Loans or Money Market LIBOR Loans or Money Market Absolute Rate Loans after notice has been given to any Bank in accordance with Section 2.4(a) or 2.6, or if Borrower shall deliver a Notice of Interest Rate Election specifying that a Euro-Dollar Loan or Money Market LIBOR Loan or Money Market Absolute Rate Loan shall be converted on a date other than the first (lst) day of the then current Interest Period applicable thereto, the Borrower shall reimburse each Bank within 15 days after certification of such Bank of such loss or expense (which shall be delivered by each such Bank to Administrative Agent for delivery to Borrower) for any resulting loss or expense incurred by it (or by an existing Participant in the related Loan), including (without limitation) any loss incurred in obtaining, liquidating or employing deposits from third parties, but excluding loss of margin for the period after any such payment or failure to borrow, continue or convert, provided that such Bank shall have delivered to Administrative Agent and Administrative Agent shall have delivered to the Borrower a certification as to the amount of such loss or expense, which certification shall set forth in reasonable detail the basis for and calculation of such loss or expense and shall be conclusive in the absence of demonstrable error.

SECTION 2.14 Computation of Interest and Fees. All interest and fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day).

SECTION 2.15 Use of Proceeds. The Borrower shall use the proceeds of the Loans for general corporate purposes, including, without limitation, the acquisition of real property to be used in the Borrower’s existing business and for general working capital needs of the Borrower; provided, however, that no Swingline Loan shall be used more than once for the purpose of refinancing another Swingline Loan, in whole or part.

SECTION 2.16 Swingline Loan Subfacility.

(a) Swingline Commitment. Subject to the terms and conditions of this Section 2.16, the Swingline Lender, in its individual capacity, agrees to make certain revolving credit loans to the Borrower (each a “Swingline Loan” and, collectively, the “Swingline Loans”) from time to time during the term hereof; provided, however, that the aggregate amount of Swingline Loans outstanding at any time shall not exceed the lesser of (i) ten percent (10%) of the aggregate Commitments, and (ii) the aggregate Commitments less all Loans then outstanding (the “Swingline Commitment”). Subject to the limitations set forth herein, any amounts repaid in respect of Swingline Loans may be reborrowed.

(b) Swingline Borrowings.

(i) Notice of Borrowing. With respect to any Swingline Borrowing, the Borrower shall give the Swingline Lender and the Administrative Agent notice in writing in the form attached hereto as Exhibit C, which is received by the Swingline Lender and Administrative Agent not later than 2:00 p.m. (New York time) on the proposed date of such Swingline Borrowing (and confirmed by telephone by such time), specifying (A) that a Swingline Borrowing is being requested, (B) the amount of such Swingline Borrowing, (C) the proposed date of such Swingline Borrowing, which shall be a Domestic Business Day, and (D) stating that no Default or Event of Default has occurred and is continuing both before and after giving effect to such Swingline Borrowing. Such notice shall be irrevocable.

(ii) Minimum Amounts. Each Swingline Borrowing shall be in a minimum principal amount of $1,000,000, or an integral multiple of $100,000 in excess thereof.

(iii) Repayment of Swingline Loans. Each Swingline Loan shall be due and payable on the earliest of (A) 5 Domestic Business Days from the date of the applicable Swingline Borrowing, (B) the date of the next Committed Borrowing or (C) the Maturity Date. In addition, in no event shall Swingline Loans be outstanding for more than ten (10) Domestic Business Days in any calendar month. If, and to the extent, any Swingline Loans shall be outstanding on the date of any Committed Borrowing, such Swingline Loans shall first be repaid from the proceeds of such Committed Borrowing prior to the disbursement of the same to the Borrower. If, and to the extent, a Committed Borrowing is not requested prior to the Maturity Date or the end of the 5-Domestic Business Day period after a Swingline Borrowing, the Borrower shall be deemed to have requested a Committed Borrowing comprised entirely of Base Rate Loans in the amount of the applicable Swingline Loan then outstanding, the proceeds of which shall be used to repay such Swingline Loan to the Swingline Lender. In addition, the Swingline Lender may, at any time, in its sole discretion, by written notice to the Borrower and the Administrative Agent, demand repayment of its Swingline Loans by way of a Committed Borrowing, in which case the Borrower shall be deemed to have requested a Committed Borrowing comprised entirely of Base Rate Loans in the amount of such Swingline Loans then outstanding, the proceeds of which shall be used to repay such Swingline Loans to the Swingline Lender. Any Committed Borrowing which is deemed requested by the Borrower in accordance with this Section 2.16(b)(iii) is hereinafter referred to as a “Mandatory Borrowing”. Each Bank hereby irrevocably agrees to make Committed Loans promptly upon receipt of notice from the Swingline Lender of any such deemed request for a Mandatory Borrowing in the amount and in the manner specified in the preceding sentences and on the date such notice is received by such Bank (or the next Domestic Business Day if such notice is received after 1:00 P.M. (New York time)) notwithstanding (I) the amount of the Mandatory Borrowing may not comply with the minimum amount of Committed Borrowings otherwise required hereunder, (II) whether any conditions specified in Section 3.2 are then satisfied, (III) whether a Default or an Event of Default then exists, (IV) failure of any such deemed request for a Committed Borrowing to be made by the time otherwise required in Section 2.2, (V) the date of such Mandatory

Borrowing (provided that such date must be a Domestic Business Day), or (VI) any termination of the Commitments immediately prior to such Mandatory Borrowing or contemporaneously therewith; provided, however, that no Bank shall be obligated to make Committed Loans in respect of a Mandatory Borrowing if a Default or an Event of Default then exists and the applicable Swingline Loan was made by the Swingline Lender without receipt of a written Notice of Borrowing in the form specified in subclause (i) above or after Administrative Agent has delivered a notice of Default or Event of Default which has not been rescinded.

(iv) Purchase of Participations. In the event that any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation , as a result of the commencement of a proceeding under the Bankruptcy Code with respect to the Borrower), then each Bank hereby agrees that it shall forthwith, upon demand, purchase (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payment received from the Borrower on or after such date and prior to such purchase) from the Swingline Lender such participations in the outstanding Swingline Loans as shall be necessary to cause each such Bank to share in such Swingline Loans ratably based upon its Pro Rata Share (determined before giving effect to any termination of the Commitments pursuant hereto), provided that (A) all interest payable on the Swingline Loans with respect to any participation shall be for the account of the Swingline Lender until but excluding the day upon which the Mandatory Borrowing would otherwise have occurred, and (B) in the event of a delay caused by any purchasing Bank between the day upon which the Mandatory Borrowing would otherwise have occurred and the time any purchase of a participation pursuant to this sentence is actually made, such purchasing Bank shall be required to pay to the Swingline Lender interest on the principal amount of such participation for each day from and including the day upon which the Mandatory Borrowing would otherwise have occurred to but excluding the date of payment for such participation, at the rate equal to the Federal Funds Rate, for the two (2) Domestic Business Days after the date the Mandatory Borrowing would otherwise have occurred, and thereafter at a rate equal to the Base Rate. Notwithstanding the foregoing, no Bank shall be obligated to purchase a participation in any Swingline Loan if a Default or an Event of Default then exists and such Swingline Loan was made by the Swingline Lender without receipt of a written Notice of Borrowing in the form

specified in subclause (i) above or after Administrative Agent has delivered a notice of Default or Event of Default which has not been rescinded.

(c) Interest Rate. Each Swingline Loan shall bear interest on the outstanding principal amount thereof, for each day from the date such Swingline Loan is made until the date it is repaid, at a rate per annum equal to the Federal Funds Rate for such day, plus the Applicable Margin for Euro-Dollar Loans.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES

In order to induce the Administrative Agent and each of the Banks which is or may become a party to this Agreement to make the Loans, the Borrower makes the following representations and warranties as of the Closing Date. Such representations and warranties shall survive the effectiveness of this Agreement, the execution and delivery of the other Loan Documents and the making of the Loans.

SECTION 4.1 Existence and Power. The Borrower is a limited partnership, duly formed and validly existing as a limited partnership under the laws of the

State of Illinois and has all powers and all material governmental licenses, authorizations, consents and approvals required to own its property and assets and carry on its business as now conducted or as it presently proposes to conduct and has been duly qualified and is in good standing in every jurisdiction in which the failure to be so qualified and/or in good standing is likely to have a Material Adverse Effect. EQR is a real estate investment trust, duly formed, validly existing and in good standing as a real estate investment trust under the laws of the State of Maryland and has all powers and all material governmental licenses, authorizations, consents and approvals required to own its property and assets and carry on its business as now conducted or as it presently proposes to conduct and has been duly qualified and is in good standing in every jurisdiction in which the failure to be so qualified and/or in good standing is likely to have a Material Adverse Effect.

SECTION 4.2 Power and Authority. The Borrower has the partnership power and authority to execute, deliver and carry out the terms and provisions of, and to consummate the transactions contemplated by, each of the Loan Documents to which it is a party and has taken all necessary partnership action, if any, to authorize the execution and delivery on behalf of the Borrower and the performance by the Borrower of, and the consummation of the transactions contemplated by, such Loan Documents. The Borrower has duly executed and delivered each Loan Document to which it is a party in accordance with the terms of this Agreement, and each such Loan Document constitutes the legal, valid and binding obligation of the Borrower, enforceable in accordance with its terms, except as enforceability may be limited by applicable insolvency, bankruptcy or other laws affecting creditors’ rights generally, or general principles of equity, whether such enforceability is considered in a proceeding in equity or at law. EQR has the power and authority to execute, deliver and carry out the terms and provisions, and the consummation of the transactions contemplated by, each of the Loan Documents on behalf of the Borrower to which the Borrower is a party and has taken all necessary action to authorize the execution and delivery on behalf of the Borrower and the performance by the Borrower of such Loan Documents.

SECTION 4.3 No Violation. Neither the execution, delivery or performance by or on behalf of the Borrower of the Loan Documents to which it is a party, nor compliance by

the Borrower with the terms and provisions thereof nor the consummation of the transactions contemplated by the Loan Documents, (i) will materially contravene any applicable provision of any law, statute, rule, regulation, order, writ, injunction or decree of any court or governmental instrumentality, (ii) will materially conflict with or result in any breach of any of the terms, covenants, conditions or provisions of, or constitute a default under, or result in the creation or imposition of (or the obligation to create or impose) any Lien upon any of the property or assets of the Borrower or any of its Consolidated Subsidiaries pursuant to the terms of, any indenture, mortgage, deed of trust, or other agreement or other instrument to which the Borrower (or of any partnership of which the Borrower is a partner) or any of its Consolidated Subsidiaries is a party or by which it or any of its property or assets is bound or to which it is subject, or (iii) will cause a material default by the Borrower under any organizational document of any Person in which the Borrower has an interest, or cause a material default under the Borrower’s agreement or certificate of limited partnership, the consequences of which conflict, breach or default would have a Material Adverse Effect, or result in or require the creation or imposition of any Lien whatsoever upon any Property (except as contemplated herein).

SECTION 4.4 Financial Information.

(a) The consolidated balance sheet of the Borrower and its Consolidated Subsidiaries, dated as of December 31, 2005, and the related consolidated statements of Borrower’s financial position for the fiscal year then ended, reported on by Ernst & Young LLP, a copy of which has been delivered to each of the Banks, fairly present, in conformity with GAAP, the consolidated financial position of the Borrower and its Consolidated Subsidiaries as of such date and their consolidated results of operations and cash flows for such fiscal year.

(b) The consolidated balance sheet of EQR, dated as of December 31, 2005, and the related consolidated statements of EQR’s financial position for the fiscal year then ended, reported on by Ernst & Young LLP and set forth in the EQR 2005 Form 10-K, a copy of which has been delivered to each of the Banks, fairly present, in conformity with GAAP, the consolidated financial position of EQR and its Consolidated Subsidiaries as of such date and

their consolidated results of operations and cash flows for such fiscal year.

(c) Since March 31, 2006, (i) except as may have been disclosed in writing to the Banks, nothing has occurred prior to the Closing Date having a Material Adverse Effect, and (ii) except as previously disclosed to the Banks, neither the Borrower nor EQR has incurred any material indebtedness or guaranty on or before the Closing Date.

SECTION 4.5 Litigation. Except as previously disclosed by the Borrower in writing to the Banks prior to the date hereof, there is no action, suit or proceeding pending against, or to the knowledge of the Borrower threatened against or affecting, nor, to the knowledge of the Borrower, any investigation of, (i) the Borrower, EQR or any of their Consolidated Subsidiaries, (ii) the Loan Documents or any of the transactions contemplated by the Loan Documents or (iii) any of their assets, before any court or arbitrator or any governmental body, agency or official in which there is a reasonable possibility of an adverse decision which could, individually or in the aggregate, have a Material Adverse Effect or which in any manner draws into question the validity or enforceability of this Agreement or the other Loan Documents.

SECTION 4.6 Compliance with ERISA. The transactions contemplated by the Loan Documents will not constitute a nonexempt prohibited transaction (as such term is defined in Section 4975 of the Code or Section 406 of ERISA) that could subject the Administrative Agent or the Banks to any tax or penalty for prohibited transactions imposed under Section 4975 of the Code or Section 502(i) of ERISA.

SECTION 4.7 Environmental Matters. The Borrower and EQR each conducts reviews of the effect of Environmental Laws on the business, operations and properties of the Borrower, EQR and Consolidated Subsidiaries of either or both when necessary in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently owned, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any license, permit or contract, any related constraints on operating activities, and any actual or potential liabilities to third

parties, including employees, and any related costs and expenses). On the basis of this review, the Borrower and EQR each has reasonably concluded that such associated liabilities and costs, including the costs of compliance with Environmental Laws, are unlikely to have a Material Adverse Effect.

SECTION 4.8 Taxes. United States Federal income tax returns of the Borrower, EQR and their Consolidated Subsidiaries have been prepared and filed through the fiscal year ended December 31, 2004. The Borrower, EQR and their Consolidated Subsidiaries have filed all United States Federal income tax returns and all other material tax returns which are required to be filed by them and have paid all taxes due pursuant to such returns or pursuant to any assessment received by the Borrower, EQR or any Consolidated Subsidiary, except such taxes, if any, as are reserved against in accordance with GAAP, such taxes as 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. The charges, accruals and reserves on the books of the Borrower, EQR and their Consolidated Subsidiaries in respect of taxes or other governmental charges are, in the opinion of the Borrower, adequate.

SECTION 4.9 Full Disclosure. All information heretofore furnished by the Borrower to the Administrative Agent or any Bank for purposes of or in connection with or pursuant to this Agreement or any transaction contemplated hereby or thereby is true and accurate in all material respects on the date as of which such information is stated or certified. The Borrower has disclosed to the Administrative Agent, in writing any and all facts existing on the Closing Date which have or may have (to the extent the Borrower can now reasonably foresee) a Material Adverse Effect.

SECTION 4.10 Solvency. On the Closing Date and after giving effect to the transactions contemplated by the Loan Documents occurring on the Closing Date, the Borrower will be Solvent.

SECTION 4.11 Use of Proceeds; Margin Regulations. All proceeds of the Loans will be used by the Borrower only in accordance with the provisions hereof. No part of the proceeds of any Loan will be used by the Borrower to purchase or carry any Margin Stock or to extend credit to

others for the purpose of purchasing or carrying any Margin Stock in any manner that might violate the provisions of Regulations T, U or X of the Federal Reserve Board. Neither the making of any Loan nor the use of the proceeds thereof will violate or be inconsistent with the provisions of Regulations T, U or X of the Federal Reserve Board.

SECTION 4.12 Governmental Approvals. No order, consent, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, any governmental or public body or authority, or any subdivision thereof, is required to authorize, or is required in connection with the execution, delivery and performance of any Loan Document or the consummation of any of the transactions contemplated thereby other than those that have already been duly made or obtained and remain in full force and effect or those which, if not made or obtained, would not have a Material Adverse Effect.

SECTION 4.13 Investment Company Act; Public Utility Holding Company Act.

which it is a party or by which it or any of its property is bound in any respect, the existence of which default is likely to result in a Material Adverse Effect.

SECTION 4.17 Compliance With Law. To the Borrower’s knowledge, the Borrower and each of the Real Property Assets are in compliance with all laws, rules, regulations, orders, judgments, writs and decrees, including, without limitation, all building and zoning ordinances and codes, the failure to comply with which is likely to have a Material Adverse Effect.

SECTION 4.18 Organizational Documents. The documents delivered pursuant to Section 3.1(f) constitute, as of the Closing Date, all of the organizational documents (together with all amendments and modifications thereof) of the Borrower and EQR. The Borrower represents that it has delivered to the Administrative Agent true, correct and complete copies, as of the Closing Date, of each of the documents set forth in this Section 4.18, except for exhibits to the Borrower’s partnership agreement identifying the current list of partners which, with the permission of the Banks, have been omitted therefrom.

Except as set forth in Sections 7.8 and 7.9 hereof, the provisions of this Article VII are solely for the benefit of Administrative Agent and the Banks, and Borrower shall not have any right to rely on or enforce any of the provisions of this Article VII. In performing its functions and duties under this Agreement, Administrative Agent shall act solely as an agent of the Banks and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for the Borrower.

SECTION 7.2 Agency and Affiliates. JPMorgan Chase Bank, N.A. shall have the same rights and powers under this Agreement as any other Bank and may exercise or refrain from exercising the same as though it were not the Administrative Agent, and JPMorgan Chase Bank, N.A. and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower, EQR or any Subsidiary or affiliate of the Borrower as if it were not the Administrative Agent hereunder, and the term “Bank” and “Banks” shall include JPMorgan Chase Bank, N.A. in its individual capacity.

be administrative in nature. Subject to the provisions of Sections 7.1, 7.5 and 7.6, Administrative Agent shall administer the Loans in the same manner as it administers its own loans.

SECTION 7.4 Consultation with Experts. As between Administrative Agent and the Banks, the Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

SECTION 7.5 Liability of Administrative Agent. As between Administrative Agent and the Banks, neither the Administrative Agent nor any of its affiliates nor any of its directors, officers, agents or employees, shall be liable for any action taken or not taken by any of them in connection herewith (i) with the consent or at the request of the Required Banks or (ii) in the absence of its own gross negligence or wilful misconduct. As between Administrative Agent and the Banks, neither the Administrative Agent nor any of its directors, officers, agents or employees, shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements of the Borrower, except with respect to payment of principal and interest; (iii) the satisfaction of any condition specified in Article III, except receipt of items required to be delivered to the Administrative Agent; or (iv) the validity, effectiveness or genuineness of this Agreement, the other Loan Documents or any other instrument or writing furnished in connection herewith.

SECTION 7.6 Indemnification. Each Bank shall, ratably in accordance with its Commitment, indemnify the Administrative Agent and its affiliates and directors,

officers, agents and employees (to the extent not reimbursed by the Borrower), against any cost, expense (including counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitee’s gross negligence or wilful misconduct) that such indemnitee may suffer or incur in connection with its duties as Administrative Agent under this Agreement, the other Loan Documents or any action taken or omitted by such indemnitee hereunder as Administrative Agent. In the event that the Administrative Agent shall, subsequent to its receipt of indemnification payment(s) from Banks in accordance with this Section, recoup any amount from the Borrower, or any other party liable therefor in connection with such indemnification, the Administrative Agent shall reimburse the Banks which previously made the payment(s) pro rata, based upon the actual amounts which were theretofore paid by each Bank. The Administrative Agent shall reimburse such Banks so entitled to reimbursement within two (2) Domestic Business Days after its receipt of such funds from the Borrower or such other party liable therefor.

SECTION 7.7 Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Bank, 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 any action under this Agreement.

SECTION 7.8 Successor Administrative Agent. The Administrative Agent may resign at any time by giving notice thereof to the Banks and the Borrower. Upon any such resignation, the Required Banks shall have the right to appoint a successor Administrative Agent, which successor Administrative Agent shall, provided no Event of Default has occurred and is then continuing, be subject to Borrower’s approval, which approval shall not be unreasonably withheld or delayed. If no successor Administrative Agent shall have been so appointed by the Required Banks and (if required) approved by the Borrower, or, if so appointed, shall not have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall

be the Administrative Agent who shall act until the Required Banks shall appoint a successor Administrative Agent. In any event, the retiring Administrative Agent shall continue to act as Administrative Agent until such time as a successor Administrative Agent shall have been so appointed by the Required Banks, approved by Borrower (if required), and assumed its duties hereunder. Upon the acceptance of its appointment as the Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The rights and duties of the Administrative Agent to be vested in any successor Administrative Agent shall include, without limitation, the rights and duties as Swingline Lender. After any retiring Administrative Agent’s resignation hereunder, the provisions of this Article shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent. For gross negligence or willful misconduct, as determined by the Required Banks (excluding for such determination the Bank serving as Administrative Agent), the Administrative Agent may be removed at any time by giving at least thirty (30) Domestic Business Days prior written notice to the Administrative Agent and Borrower. Such resignation or removal shall take effect upon the acceptance of appointment by a successor Administrative Agent in accordance with the provisions of this Section 7.8.

(10) Domestic Business Days and provide a written explanation of the reasons behind any objection, such Lender shall be deemed to have approved of or consented to, as applicable, the recommendation or determination of the Administrative Agent described in such request. Each Bank shall reply promptly, but in any event within ten (10) Domestic Business Days after receipt of the request therefor from Administrative Agent (the “Bank Reply Period”). Unless a Bank shall give written notice to Administrative Agent that it objects to the recommendation or determination of Administrative Agent within the Bank Reply Period, such Bank shall be deemed to have approved of or consented to such recommendation or determination. With respect to decisions requiring the approval of the Required Banks or all the Banks, Administrative Agent shall submit its recommendation or determination for approval of or consent to such recommendation or determination to all Banks and upon receiving the required approval or consent shall follow the course of action or determination of the Required Banks (and each non-responding Bank shall be deemed to have concurred with such recommended course of action) or all the Banks, as the case may be.

ARTICLE VIII

CHANGE IN CIRCUMSTANCES

SECTION 8.1 Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any Euro-Dollar Borrowing or Money Market LIBOR Loan:

(a) the Administrative Agent determines in good faith that deposits in dollars (in the applicable amounts) are not being offered in the relevant market for such Interest Period, or

(b) Banks having 50% or more of the aggregate amount of the Commitments advise the Administrative Agent that the Euro-Dollar Rate, as determined by the Administrative Agent will not adequately and fairly reflect the cost to each such Bank of funding its Euro-Dollar Loans for such Interest Period,

the Administrative Agent shall forthwith give notice thereof to the Borrower and the Banks, whereupon until the Administrative Agent notifies the Borrower that the

circumstances giving rise to such suspension no longer exist, the obligations of the Banks to make Euro-Dollar Loans shall be suspended. Unless the Borrower notifies the Administrative Agent at least two Domestic Business Days before the date of (i) any Euro-Dollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Base Rate Borrowing, or (ii) any Money Market LIBOR Borrowing for which a Notice of Money Market Borrowing has previously been given, the Money Market LIBOR Loans comprising such Borrowing shall bear interest for each day from and including the first day to but excluding the last day of the Interest Period applicable thereto at the Base Rate for such day. For purposes of Section 8.1(b), in determining whether the Euro-Dollar Rate, as determined by Administrative Agent, will not adequately and fairly reflect the cost to any Bank of funding its Euro-Dollar Loans for such Interest Period, such determination will be based solely on the ability of such Bank to obtain matching funds in the London interbank market at a reasonably equivalent rate.

SECTION 8.2 Illegality. If, on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) made after the Closing Date of any such authority, central bank or comparable agency shall make it unlawful for any Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans, the Administrative Agent shall forthwith give notice thereof to the other Banks and the Borrower, whereupon until such Bank notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Bank in case of the event described above to make Euro-Dollar Loans, shall be suspended. With respect to Euro-Dollar Loans, before giving any notice to the Administrative Agent pursuant to this Section, such Bank shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank shall determine that it may not lawfully continue to maintain and fund any

of its outstanding Euro-Dollar Loans to maturity and shall so specify in such notice, the Borrower shall be deemed to have delivered a Notice of Interest Rate Election and such Euro-Dollar Loan shall be converted as of such date to a Base Rate Loan (without payment of any amounts that Borrower would otherwise be obligated to pay pursuant to Section 2.13 hereof with respect to Loans converted pursuant to this Section 8.2) in an equal principal amount from such Bank (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks), and such Bank shall make such a Base Rate Loan.

If, at any time, it shall be unlawful for any Bank to make, maintain or fund its Euro-Dollar Loans, the Borrower shall have the right, upon five (5) Domestic Business Day’s notice to the Administrative Agent, to either (x) cause a bank, reasonably acceptable to the Administrative Agent, to offer to purchase the Commitments of such Bank for an amount equal to such Bank’s outstanding Loans and all amounts due such Bank hereunder (including, without limitation, interest, Facility Fees, Unused Fees and all amounts payable pursuant to Section 2.13), and to become a Bank hereunder, or obtain the agreement of one or more existing Banks to offer to purchase the Commitments of such Bank for such amount, which offer such Bank is hereby required to accept, or (y) to repay in full all Loans then outstanding of such Bank, together with interest thereon, Facility Fees and all other amounts due such Bank hereunder (including, without limitation, amounts payable pursuant to Section 2.13), upon which event, such Bank’s Commitments shall be deemed to be cancelled pursuant to Section 2.11(e). Any Bank subject to this paragraph shall retain the benefits of Sections 2.16(f), 2.16(g), 8.3, 8.4 and 9.3 for the period prior to such purchase or cancellation.

SECTION 8.3 Increased Cost and Reduced Return.

(a) If, on or after (x) the date hereof in the case of Committed Loans made pursuant to Section 2.1, or (y) the date of the related Money Market Quote, in the case of any Money Market Loan, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Applicable Lending Office) with any request

or directive (whether or not having the force of law) made after the Closing Date of any such authority, central bank or comparable agency, shall impose, modify or deem applicable any reserve (including, without limitation, any such requirement imposed by the Federal Reserve Board (but excluding with respect to any Euro-Dollar Loan any such requirement to the extent reflected in an applicable Euro-Dollar Reserve Percentage)), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Applicable Lending Office) or shall impose on any Bank (or its Applicable Lending Office) or on the London interbank market any other condition materially more burdensome in nature, extent or consequence than those in existence as of the Closing Date affecting such Bank’s Euro-Dollar Loans, its Note, or its obligation to make Euro-Dollar Loans, and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making or maintaining any Euro-Dollar Loan, or to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Note with respect to such Euro-Dollar Loans, by an amount deemed by such Bank to be material, then, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts (based upon a reasonable allocation thereof by such Bank to the Euro-Dollar Loans made by such Bank hereunder) as will compensate such Bank for such increased cost or reduction to the extent such Bank generally imposes such additional amounts on other borrowers of such Bank in similar circumstances.

(b) If any Bank shall have reasonably determined that, after the date hereof, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any law, rule or regulation regarding capital adequacy, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank any request or directive regarding capital adequacy (whether or not having the force of law) made after the Closing Date of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank’s obligations hereunder to a level below that which such Bank (or its Parent) could have achieved but for such adoption, change, request or directive

(taking into consideration its policies with respect to capital adequacy) by an amount reasonably deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank (or its Parent) for such reduction to the extent such Bank generally imposes such additional amounts on other borrowers of such Bank in similar circumstances.

(c) Each Bank will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank shall fail to notify Borrower of any such event within 90 days following the end of the month during which such event occurred, then Borrower’s liability for any amounts described in this Section incurred by such Bank as a result of such event shall be limited to those attributable to the period occurring subsequent to the ninetieth (90th) day prior to the date upon which such Bank actually notified Borrower of the occurrence of such event. A certificate of any Bank claiming compensation under this Section and setting forth a reasonably detailed calculation of the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of demonstrable error. In determining such amount, such Bank may use any reasonable averaging and attribution methods.

(d) If at any time, any Bank shall be owed amounts pursuant to this Section 8.3, the Borrower shall have the right, upon five (5) Domestic Business Day’s notice to the Administrative Agent to either (x) cause a bank, reasonably acceptable to the Administrative Agent, to offer to purchase the Commitments of such Bank for an amount equal to such Bank’s outstanding Loans and all amounts due such Bank hereunder (including, without limitation, interest, Facility Fees and all amounts payable pursuant to Section 2.13 and this Section 8.3), and to become a Bank hereunder, or to obtain the agreement of one or more existing Banks to offer to purchase the Commitments of such Bank for such amount, which offer such Bank is hereby required to accept, or (y) to repay in full all Loans then outstanding of such Bank, together with interest thereon, Facility Fees and all

other amounts due such Bank hereunder (including, without limitation, amounts payable pursuant to Section 2.13 and this Section 8.3), upon which event, such Bank’s Commitment shall be deemed to be cancelled pursuant to Section 2.11(e). Any Bank subject to this Section 8.3(d) shall retain the benefits of Sections 2.16(f), 2.16(g), 8.3, 8.4 and 9.3 for the period prior to such purchase or cancellation.

SECTION 8.4 Taxes.

(a) Any and all payments by the Borrower to or for the account of any Bank or the Administrative Agent hereunder or under any other Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and the Administrative Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Bank or the Administrative Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its income, and franchise or similar taxes imposed on it, by the jurisdiction of such Bank’s Applicable Lending Office or any political subdivision thereof or by any other jurisdiction (or any political subdivision thereof) as a result of a present or former connection between such Bank or Administrative Agent and such other jurisdiction or by the United States (all such non-excluded taxes, duties, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Non-Excluded Taxes”). If the Borrower shall be required by law to deduct any Non-Excluded Taxes from or in respect of any sum payable hereunder or under any Note, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 8.4) such Bank or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 9.1, the original or a certified copy of a receipt evidencing payment thereof.

(b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, or charges or similar levies which arise from any payment made hereunder or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note (hereinafter referred to as “Other Taxes”).

(c) The Borrower agrees to indemnify each Bank and the Administrative Agent for the full amount of Non-Excluded Taxes or Other Taxes (including, without limitation, any Non-Excluded Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 8.4) paid by such Bank or the Administrative Agent (as the case may be) and, so long as such Bank or Administrative Agent has promptly paid any such Non-Excluded Taxes or Other Taxes, any liability for penalties and interest arising therefrom or with respect thereto. This indemnification shall be made within 15 days from the date such Bank or the Administrative Agent (as the case may be) makes demand therefor.

(d) Each Bank organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Bank listed on the signature pages hereof and on or prior to the date on which it becomes a Bank in the case of each other Bank, shall provide the Borrower with an Internal Revenue Service Form W-8BEN or W-8ECI, as appropriate, or any successor form prescribed by the Internal Revenue Service, and shall provide Borrower with two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to Borrower, certifying (i) in the case of a Form 1001, that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States, and (ii) in the case of being under Sections 1442(c)(1) and 1442(a) of the Code, that it is entitled to an exemption from United States backup withholding tax. If the form provided by a Bank at the time such Bank first becomes a party to this Agreement indicates a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be

considered excluded from “Non-Excluded Taxes” as defined in Section 8.4(a).

(e) For any period with respect to which a Bank has failed to provide the Borrower with the appropriate form pursuant to Section 8.4(d) (unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which a form originally was required to be provided), such Bank shall not be entitled to indemnification under Section 8.4(c) with respect to Non-Excluded Taxes imposed by the United States; provided, however, that should a Bank, which is otherwise exempt from or subject to a reduced rate of withholding tax, become subject to Non-Excluded Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Taxes so long as Borrower shall incur no cost or liability as a result thereof.

(f) If the Borrower is required to pay additional amounts to or for the account of any Bank pursuant to this Section 8.4, then such Bank will change the jurisdiction of its Applicable Lending Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the judgment of such Bank, is not otherwise disadvantageous to such Bank.

(g) If, at any time, any Bank shall be owed amounts pursuant to this Section 8.4, the Borrower shall have the right, upon five (5) Domestic Business Day’s notice to the Administrative Agent to either (x) cause a bank, reasonably acceptable to the Administrative Agent, to offer to purchase the Commitments of such Bank for an amount equal to such Bank’s outstanding Loans and all amounts due such Bank hereunder (including, without limitation, interest, Facility Fees, Unused Fees and all amounts payable pursuant to Section 2.13 and this Section 8.4), and to become a Bank hereunder, or to obtain the agreement of one or more existing Banks to offer to purchase the Commitments of such Bank for such amount, which offer such Bank is hereby required to accept, or (y) to repay in full all Loans then outstanding of such Bank, together with interest thereon, Facility Fees, Unused Fees and all other amounts due such Bank hereunder (including, without limitation, amounts payable pursuant to Section 2.13 and this Section 8.4), upon which event, such Bank’s Commitment shall be deemed to be cancelled pursuant to Section 2.11(c). Any Bank subject to this Section 8.4(d) shall retain the benefits of Sections

2.16(f), 2.16(g), 8.3, 8.4 and 9.3 for the period prior to such purchase or cancellation.

SECTION 8.5 Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Bank to make Euro-Dollar Loans has been suspended pursuant to Section 8.2 or (ii) any Bank has demanded compensation under Section 8.3 or 8.4 with respect to its Euro-Dollar Loans and the Borrower shall, by at least five Euro-Dollar Business Days’ prior notice to such Bank through the Administrative Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer exist:

(a) Borrower shall be deemed to have delivered a Notice of Interest Rate Election with respect to such affected Euro-Dollar Loans and thereafter all Loans which would otherwise be made by such Bank as Euro-Dollar Loans shall be made instead as Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks), and

(b) after each of its Euro-Dollar Loans has been repaid, all payments of principal which would otherwise be applied to repay such Euro-Dollar Loans shall be applied to repay its Base Rate Loans instead, and

(c) Borrower will not be required to make any payment which would otherwise be required by Section 2.13 with respect to such Euro-Dollar Loans converted to Base Rate Loans pursuant to clause (a) above.

(b) The Borrower agrees to indemnify the Administrative Agent and each Bank, their respective affiliates and the respective directors, officers, agents and employees of the foregoing (each an “Indemnitee”) and hold each Indemnitee harmless from and against any and all liabilities, losses, damages, costs and expenses of any kind, including, without limitation, the reasonable fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding that may at any time (including, without limitation, at any time following the payment of the Obligations) be asserted against any Indemnitee, as a result of, or arising out of, or in any way related to or by reason of, (i) any of the transactions contemplated by the Loan Documents or the execution, delivery or performance of any Loan Document, (ii) any

violation by the Borrower, EQR or the Environmental Affiliates of any applicable Environmental Law, (iii) any Environmental Claim arising out of the management, use, control, ownership or operation of property or assets by the Borrower, EQR or any of the Environmental Affiliates, including, without limitation, all on-site and off-site activities of Borrower or any Environmental Affiliate involving Materials of Environmental Concern, (iv) the breach of any environmental representation or warranty set forth herein, but excluding those liabilities, losses, damages, costs and expenses (a) for which such Indemnitee has been compensated pursuant to the terms of this Agreement, (b) incurred solely by reason of the gross negligence, wilful misconduct, bad faith or fraud of any Indemnitee as finally determined by a court of competent jurisdiction, (c) violations of Environmental Laws relating to a Property which are caused by the act or omission of such Indemnitee after such Indemnitee takes possession of such Property or (d) any liability of such Indemnitee to any third party based upon contractual obligations of such Indemnitee owing to such third party which are not expressly set forth in the Loan Documents. In addition, the indemnification set forth in this Section 9.3(b) in favor of any director, officer, agent or employee of Administrative Agent or any Bank shall be solely in his or her respective capacity as such director, officer, agent or employee.

SECTION 9.4 Sharing of Set-Offs. In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence and during the continuance of any Event of Default, each Bank is hereby authorized at any time or from time to time, without presentment, demand, protest or other notice of any kind to the Borrower or to any other Person, any such notice being hereby expressly waived, but subject to the prior consent of the Administrative Agent, to set off and to appropriate and apply any and all deposits (general or special, time or demand, provisional or final) and any other indebtedness at any time held or owing by such Bank (including, without limitation, by branches and agencies of such Bank wherever located) to or for the credit or the account of the Borrower against and on account of the Obligations of the Borrower then due and payable to such Bank under this Agreement or under any of the other Loan Documents, including, without limitation, all interests in

Obligations purchased by such Bank. Each Bank agrees that if it shall by exercising any right of set-off or counterclaim or otherwise (except pursuant to Sections 8.2, 8.3, 8.4 or 9.6), receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Note held by it, the Bank receiving such proportionately greater payment shall purchase such participations in the Notes held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Notes held by the Banks shall be shared by the Banks pro rata; provided that nothing in this Section shall impair the right of any Bank to exercise any right of set-off or counterclaim it may have to any deposits not received in connection with the Loans and to apply the amount subject to such exercise to the payment of indebtedness of the Borrower other than its indebtedness under the Notes. The Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in a Note, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of set-off or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. Notwithstanding anything to the contrary contained herein, any Bank may, by separate agreement with the Borrower, waive its right to set off contained herein or granted by law and any such written waiver shall be effective against such Bank under this Section 9.4.

SECTION 9.5 Amendments and Waivers. Any provision of this Agreement or the Notes or other Loan Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Banks (and, if the rights or duties of the Administrative Agent or the Swingline Lender in its capacity as Administrative Agent or Swingline Lender, as applicable, are affected thereby, by the Administrative Agent or Swingline Lender, as applicable); provided that no such amendment or waiver with respect to this Agreement, the Notes or any other Loan Documents shall, unless signed by all the Banks, (i) increase or decrease the Commitment of any Bank (except for a ratable decrease in the Commitments of all Banks) or subject any Bank to any additional obligation, (ii) reduce the principal of or rate of interest on any Loan or any fees hereunder, (iii) postpone the date fixed for any payment of principal of or interest on any

Loan or any fees hereunder or for any reduction or termination of any Commitment, (iv) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Notes, or the number of Banks, which shall be required for the Banks or any of them to take any action under this Section or any other provision of this Agreement, (v) release the EQR Guaranty or, except as provided below, any Down REIT Guaranty, (vi) modify the definition of “Required Banks”, or (vii) modify the provisions of this Section 9.5. At such time as the Borrower shall sell its interest in any Down REIT Guarantor to an unaffiliated third party in an arms-length transaction, the Down REIT Guaranty of such Down REIT Guarantor shall be deemed to have terminated and released, and the Banks hereby authorize the Administrative Agent to enter into an agreement, confirming the termination and release of such Down REIT Guaranty, at the Borrower’s sole cost and expense.

SECTION 9.6 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign or otherwise transfer any of its rights under this Agreement or the other Loan Documents without the prior written consent of all Banks and the Administrative Agent and any Bank may not assign or otherwise transfer any of its interest under this Agreement except as permitted in subsection (b) and (c) of this Section 9.6.

(b) Any Bank may at any time grant (i) from and after December 15, 2006 and prior to the occurrence of an Event of Default, to an existing Bank or one or more banks, finance companies, insurance companies or other financial institutions in minimum amounts of not less than $5,000,000 (or any lesser amount in the case of participations to an existing Bank or in the case of participations with respect to Money Market Loans only) (it being understood that no Bank may hold Commitments of which less than $10,000,000 in the aggregate is for its own account, unless its Commitments shall have been reduced to zero) and (ii) after the occurrence and during the continuance of an Event of Default, to any Person in any amount (in each case, a “Participant”), participating interests in its Commitment or any or all of its Loans, with (and subject to) the consent of, provided that no Event of Default shall have occurred and be continuing, the Borrower (other than with respect to

Money Market Loans), which consent shall not be unreasonably withheld or delayed. The Administrative Agent shall be notified by any such Bank of any such participation prior to the same becoming effective. Any participation made during the continuation of an Event of Default shall not be affected by the subsequent cure of such Event of Default. In the event of any such grant by a Bank of a participating interest to a Participant, whether or not upon notice to the Borrower and the Administrative Agent, such Bank shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement. Any agreement pursuant to which any Bank may grant such a participating interest shall provide that such Bank shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement described in clause (i), (ii), (iii), (iv) or (v) of Section 9.5 without the consent of the Participant. The Borrower agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Article VIII with respect to its participating interest. An assignment or other transfer which is not permitted by subsection (c) or (d) below shall be given effect for purposes of this Agreement only to the extent of, and subject to the restrictions with respect to, a participating interest granted in accordance with this subsection (b).

(c) Any Bank may at any time assign to (i) from and after December 15, 2006 and prior to the occurrence of an Event of Default, (A) an existing Bank, (B) one or more banks, finance companies, insurance or other financial institutions which (1) has (or, in the case of a bank which is a subsidiary, such bank’s parent has) a rating of its senior debt obligations of not less than Baa-1 by Xxxxx’x or a comparable rating by a rating agency acceptable to Administrative Agent and (2) has total assets in excess of Ten Billion Dollars ($10,000,000,000), or (C) with the prior consent and approval of the Administrative Agent and Borrower, a wholly-owned affiliate of such transferor Bank if such transferor Bank then meets the requirements of clause (i)(B) or, if such transferor Bank’s parent then meets the requirements of clause (i)(B), a wholly-owned

affiliate of such parent, in each case in minimum amounts of not less than Ten Million Dollars ($10,000,000) and integral multiples of One Million Dollars ($1,000,000) thereafter (or any lesser amount in the case of assignments to an existing Bank) (it being understood that no Bank may hold Commitments of less than $10,000,000 in the aggregate, unless its Commitments shall have been reduced to zero) and (ii) after the occurrence and during the continuance of an Event of Default, to any Person in any amount (in each case, an “Assignee”), all or a proportionate part of all, of its rights and obligations under this Agreement, the Notes and the other Loan Documents, and, in either case, such Assignee shall assume such rights and obligations, pursuant to a Transfer Supplement in substantially the form of Exhibit “E” hereto executed by such Assignee and such transferor Bank, with (and subject to) the consent of the Administrative Agent and, provided that no Event of Default shall have occurred and be continuing, the Borrower, which consent shall not be unreasonably withheld or delayed; provided that if an Assignee is an affiliate of such transferor Bank which meets the requirements of clause (i)(B) above or was a Bank immediately prior to such assignment, no such consent shall be required; and provided further that such assignment may, but need not, include rights of the transferor Bank in respect of outstanding Money Market Loans. Upon execution and delivery of such instrument and payment by such Assignee to such transferor Bank of an amount equal to the purchase price agreed between such transferor Bank and such Assignee, such Assignee shall be a Bank party to this Agreement and shall have all the rights and obligations of a Bank with a Commitment as set forth in such instrument of assumption, and no further consent or action by any party shall be required and the transferor Bank shall be released from its obligations hereunder to a corresponding extent. Upon the consummation of any assignment pursuant to this subsection (c), the transferor Bank, the Administrative Agent and the Borrower shall make appropriate arrangements so that, if required, a new Note is issued to the Assignee. In connection with any such assignment, the transferor Bank shall pay to the Administrative Agent an administrative fee for processing such assignment in the amount of $2,500 provided that such fee shall be paid by the Assignee if such assignment is required by Section 8.2, 8.3 or 8.4. If the Assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Administrative Agent certification as to exemption from deduction or withholding of any United States federal income taxes in accordance with Section 8.4.

Any assignment made during the continuation of an Event of Default shall not be affected by any subsequent cure of such Event of Default.

(d) Any Bank (each, a “Designating Lender”) may at any time designate one Designated Lender to fund Money Market Loans on behalf of such Designating Lender subject to the terms of this Section 9.6(d) and the provisions in Sections 9.6(b) and (c) shall not apply to such designation. No Bank may designate more than one (1) Designated Lender at any one time. The parties to each such designation shall execute and deliver to the Administrative Agent for its acceptance a Designation Agreement. Upon such receipt of an appropriately completed Designation Agreement executed by a Designating Lender and a designee representing that it is a Designated Lender, the Administrative Agent will accept such Designation Agreement and will give prompt notice thereof to the Borrower, whereupon, (i) the Borrower shall execute and deliver to the Designating Lender a Designated Lender Note payable to the order of the Designated Lender, (ii) from and after the effective date specified in the Designation Agreement, the Designated Lender shall become a party to this Agreement with a right (subject to the provisions of Section 2.3(b)) to make Money Market Loans on behalf of its Designating Lender pursuant to Section 2.3 after the Borrower has accepted a Money Market Loan (or portion thereof) of the Designating Lender, and (iii) the Designated Lender shall not be required to make payments with respect to any obligations in this Agreement except to the extent of excess cash flow of such Designated Lender which is not otherwise required to repay obligations of such Designated Lender which are then due and payable; provided, however, that regardless of such designation and assumption by the Designated Lender, the Designating Lender shall be and remain obligated to the Borrower, the Administrative Agent and the Banks for each and every obligation of the Designating Lender and its related Designated Lender with respect to this Agreement, including, without limitation, any indemnification obligations under Section 7.6 hereof and any sums otherwise payable to the Borrower by the Designated Lender. Each Designating Lender shall serve as the administrative agent of the Designated Lender and shall on behalf of, and to the exclusion of, the Designated Lender: (i) receive any and all payments made for the benefit of the Designated Lender and (ii) give and receive all communications and notices and take all actions hereunder, including, without limitation, votes, approvals, waivers, consents and amendments under or relating to this Agreement

and the other Loan Documents. Any such notice, communication, vote, approval, waiver, consent or amendment shall be signed by the Designating Lender as administrative agent for the Designated Lender and shall not be signed by the Designated Lender on its own behalf and shall be binding upon the Designated Lender to the same extent as if signed by the Designated Lender on its own behalf. The Borrower, the Administrative Agent and the Banks may rely thereon without any requirement that the Designated Lender sign or acknowledge the same. No Designated Lender may assign or transfer all or any portion of its interest hereunder or under any other Loan Document, other than assignments to the Designating Lender which originally designated such Designated Lender or otherwise in accordance with the provisions of Sections 9.6 (b) and (c).

(e) Any Bank may at any time assign all or any portion of its rights under this Agreement and its Note to a Federal Reserve Bank. No such assignment shall release the transferor Bank from its obligations hereunder.

(f) No Assignee, Participant or other transferee of any Bank’s rights shall be entitled to receive any greater payment under Section 8.3 or 8.4 than such Bank would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower’s prior written consent or by reason of the provisions of Section 8.2, 8.3 or 8.4 requiring such Bank to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist.

SECTION 9.7 Collateral. Each of the Banks represents to the Administrative Agent and each of the other Banks that it in good faith is not relying upon any “margin stock” (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement.

SECTION 9.8 Governing Law; Submission to Jurisdiction.

(a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW).

100

(b) Any legal action or proceeding with respect to this Agreement or any other Loan Document and any action for enforcement of any judgment in respect thereof may be brought in the courts of the State of New York or of the United States of America for the Southern District of New York, and, by execution and delivery of this Agreement, the Borrower hereby accepts for itself and in respect of its property, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts and appellate courts from any thereof. The Borrower irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the hand delivery, or mailing of copies thereof by registered or certified mail, postage prepaid, to the Borrower at its address set forth below. The Borrower hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Agreement or any other Loan Document brought in the courts referred to above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum. Nothing herein shall affect the right of the Administrative Agent to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Borrower in any other jurisdiction.

SECTION 9.9 Counterparts; Integration; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective upon receipt by the Administrative Agent and the Borrower of counterparts hereof signed by each of the parties hereto (or, in the case of any party as to which an executed counterpart shall not have been received, receipt by the Administrative Agent in form satisfactory to it of telegraphic or other written confirmation from such party of execution of a counterpart hereof by such party).

SECTION 9.10 WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE ADMINISTRATIVE AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY

101

LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 9.11 Survival. All indemnities set forth herein (including, without limitation, Sections 2.16(g), 8.4 and 9.3) shall survive the execution and delivery of this Agreement and the other Loan Documents and the making and repayment of the Obligations.

SECTION 9.12 Domicile of Loans. Each Bank may transfer and carry its Loans at, to or for the account of any domestic or foreign branch office, subsidiary or affiliate of such Bank.

SECTION 9.13 Limitation of Liability. No claim may be made by the Borrower or any other Person acting by or through Borrower against the Administrative Agent or any Bank or the affiliates, directors, officers, employees, attorneys or agent of any of them for any 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 by the other Loan Documents, or any act, omission or event occurring in connection therewith; and the Borrower hereby waives, releases and agrees not to xxx upon any claim for any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

SECTION 9.14 Recourse Obligation. This Agreement and the Obligations hereunder are fully recourse to the Borrower and to EQR pursuant to the EQR Guaranty and to any Down REIT Guarantor pursuant to any Down REIT Guaranty. Notwithstanding the foregoing, no recourse under or upon any obligation, covenant, or agreement contained in this Agreement shall be had against any officer, director, shareholder or employee of the Borrower or any officer, director, shareholder or employee of EQR except in the event of fraud or misappropriation of funds on the part of such officer, director, shareholder or employee.

SECTION 9.15 Confidentiality. The Administrative Agent and each Bank shall use reasonable efforts to assure that information about Borrower, EQR and its Subsidiaries and Investment Affiliates, and the Properties thereof and their operations, affairs and financial condition, not generally disclosed to the public, which is furnished to Administrative Agent or any Bank pursuant to the provisions hereof or any other Loan Document is used only for the

102

purposes of this Agreement and shall not be divulged to any Person other than the Administrative Agent, the Banks, and their affiliates and respective officers, directors, employees and agents who are actively and directly participating in the evaluation, administration or enforcement of the Loan, this Agreement, the Loan Documents and the extension of credit hereunder, except: (a) to their attorneys and accountants, (b) in connection with the enforcement of the rights and exercise of any remedies of the Administrative Agent and the Banks hereunder and under the other Loan Documents, (c) in connection with assignments and participations and the solicitation of prospective assignees and participants referred to in Section 9.6 hereof, who have agreed in writing to be bound by a confidentiality agreement substantially equivalent to the terms of this Section 9.15, and (d) as may otherwise be required or requested by any regulatory authority having jurisdiction over the Administrative Agent or any Bank or by any applicable law, rule, regulation or judicial process.

SECTION 9.16 Bank’s Failure to Fund.

(a) Unless the Administrative Agent shall have received notice from a Bank prior to the date of any Borrowing that such Bank will not make available to the Administrative Agent such Bank’s share of such Borrowing, the Administrative Agent may assume that such Bank has made such share available to the Administrative Agent on the date of such Borrowing in accordance with subsection (b) of Section 2.4 or Section 2.16(e), and the Administrative Agent may, in reliance upon such assumption, make available to Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made such share available to the Administrative Agent, such Bank and Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, in accordance with the provisions of Section 2.4(c) or Section 2.16(e). If such Bank shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Bank’s Loan included in such Borrowing for purposes of this Agreement as of the date of such Borrowing. Nothing contained in this Section or Sections 2.4(c) or 2.16(e) shall be deemed to reduce the Commitment of any Bank or in any way affect the rights of Borrower with respect to any defaulting Bank or Administrative Agent. The failure of any Bank to make available to the Administrative Agent such Bank’s share of any Borrowing in accordance with Sections 2.4(b) or 2.16(e)

103

shall not relieve any other Bank of its obligations to fund its Commitment, in accordance with the provisions hereof.

(b) If a Bank does not remit to Administrative Agent such Bank’s Pro Rata Share of a Loan in accordance herewith, then neither Administrative Agent nor the other Banks shall be required or obligated to fund such Bank’s Pro Rata Share of such Loan.

(i) “Defaulting Bank” shall mean any Bank which (x) does not remit to the Administrative Agent such Bank’s Pro Rata Share of a Loan in accordance herewith for a period of five (5) Domestic Business Days after notice of such failure from Administrative Agent, (y) shall otherwise fail to perform such Bank’s obligations under the Loan Documents for a period of five (5) Domestic Business Days after notice of such failure from Administrative Agent, or (z) shall fail to pay the Administrative Agent or any other Bank, as the case may be, upon demand, such Bank’s Pro Rata Share of any costs, expenses or disbursements incurred or made by the Administrative Agent and payable by such Bank pursuant to the terms of the Loan Documents for a period of five (5) Domestic Business Days after notice of such failure from Administrative Agent, and in all cases, such failure is not as a result of a good faith dispute as to whether such advance is properly required to be made pursuant to the provisions of this Agreement, or as to whether such other performance or payment is properly required pursuant to the provisions of this Agreement.

(ii) “Junior Creditor” means any Defaulting Bank which has not (x) fully cured each and every default on its part under the Loan Documents and (y) unconditionally tendered to the Administrative Agent such Defaulting Bank’s Pro Rata Share of all costs, expenses and disbursements required to be paid or reimbursed pursuant to the terms of the Loan Documents.

(iii) “Payment in Full” means, as of any date, the receipt by the Banks who are not Junior Creditors of an amount of cash, in lawful currency of the United States, sufficient to indefeasibly pay in full all Senior Debt.

(iv) “Senior Debt” means (x) collectively, any and all indebtedness, obligations and liabilities of the

104

Borrower to the Banks who are not Junior Creditors, or any of them, from time to time, whether fixed or contingent, direct or indirect, joint or several, due or not due, liquidated or unliquidated, determined or undetermined, arising by contract, operation of law or otherwise, whether on open account or evidenced by one or more instruments, and whether for principal, premium, interest (including, without limitation, interest accruing after the filing of a petition initiating any proceeding referred to in Section 6.1(f) or (g)), reimbursement for fees, indemnities, costs, expenses or otherwise, which arise under, in connection with or in respect of the Loans or the Loan Documents, and (y) any and all deferrals, renewals, extensions and refundings of, or amendments, restatements, rearrangements, modifications or supplements to, any such indebtedness, obligation or liability.

(v) “Subordinated Debt” means (x) any and all indebtedness, obligations and liabilities of Borrower to one or more Junior Creditors from time to time, whether fixed or contingent, direct or indirect, joint or several, due or not due, liquidated or unliquidated, determined or undetermined, arising by contract, operation of law or otherwise, whether on open account or evidenced by one or more instruments, and whether for principal, premium, interest (including, without limitation, interest accruing after the filing of a petition initiating any proceeding referred to in Section 6.1(f) or (g)), reimbursement for fees, indemnities, costs, expenses or otherwise, which arise under, in connection with or in respect of the Loans or the Loan Documents, and (y) any and all deferrals, renewals, extensions and refundings of, or amendments, restatements, rearrangements, modifications or supplements to, any such indebtedness, obligation or liability.

(d) Immediately upon a Bank’s becoming a Junior Creditor, no Junior Creditor shall, prior to Payment in Full of all Senior Debt:

(i) accelerate, demand payment of, xxx upon, collect, or receive any payment upon, in any manner, or satisfy or otherwise discharge, any Subordinated Debt, whether for principal, interest or otherwise;

(ii) take or enforce any Liens to secure Subordinated Debt or attach or levy upon any assets of Borrower to enforce any Subordinated Debt;

105

(iii) enforce or apply any security for any Subordinated Debt; or

(iv) incur any debt or liability, or the like, to, or receive any loan, return of capital, advance, gift or any other property from, the Borrower.

(e) In the event of:

(i) any insolvency, bankruptcy, receivership, liquidation, dissolution, reorganization, readjustment, composition or other similar proceeding relating to Borrower;

(ii) any liquidation, dissolution or other winding-up of the Borrower, voluntary or involuntary, whether or not involving insolvency, reorganization or bankruptcy proceedings;

(iii) any assignment by the Borrower for the benefit of creditors;

(iv) any sale or other transfer of all or substantially all assets of the Borrower; or

(v) any other marshaling of the assets of the Borrower;

each of the Banks shall first have received Payment in Full of all Senior Debt before any payment or distribution, whether in cash, securities or other property, shall be made in respect of or upon any Subordinated Debt. Any payment or distribution, whether in cash, securities or other property that would otherwise be payable or deliverable in respect of Subordinated Debt to any Junior Creditor but for this Agreement shall be paid or delivered directly to the Administrative Agent for distribution to the Banks in accordance with this Agreement until Payment in Full of all Senior Debt. If any Junior Creditor receives any such payment or distribution, it shall promptly pay over or deliver the same to the Administrative Agent for application in accordance with the preceding sentence.

(f) Each Junior Creditor shall file in any bankruptcy or other proceeding of Borrower in which the filing of claims is required by law, all claims relating to Subordinated Debt that such Junior Creditor may have against Borrower and assign to the Banks who are not Junior

106

Creditors all rights of such Junior Creditor thereunder. If such Junior Creditor does not file any such claim prior to forty-five (45) days before the expiration of the time to file such claim, Administrative Agent, as attorney-in-fact for such Junior Creditor, is hereby irrevocably authorized to do so in the name of such Junior Creditor or, in Administrative Agent’s sole discretion, to assign the claim to a nominee and to cause proof of claim to be filed in the name of such nominee. The foregoing power of attorney is coupled with an interest and cannot be revoked. The Administrative Agent shall, to the exclusion of each Junior Creditor, have the sole right, subject to Section 9.5 hereof, to accept or reject any plan proposed in any such proceeding and to take any other action that a party filing a claim is entitled to take. In all such cases, whether in administration, bankruptcy or otherwise, the Person or Persons authorized to pay such claim shall pay to Administrative Agent the amount payable on such claim and, to the full extent necessary for that purpose, each Junior Creditor hereby transfers and assigns to the Administrative Agent all of the Junior Creditor’s rights to any such payments or distributions to which Junior Creditor would otherwise be entitled.

(g) (i) If any payment or distribution of any character or any security, whether in cash, securities or other property, shall be received by any Junior Creditor in contravention of any of the terms hereof, such payment or distribution or security shall be received for the benefit of, and shall promptly be paid over or delivered and transferred to, Administrative Agent for application to the payment of all Senior Debt, to the extent necessary to achieve Payment in Full. In the event of the failure of any Junior Creditor to endorse or assign any such payment, distribution or security, Administrative Agent is hereby irrevocably authorized to endorse or assign the same as attorney-in-fact for such Junior Creditor.

(ii) Each Junior Creditor shall take such action (including, without limitation, the execution and filing of a financing statement with respect to this Agreement and the execution, verification, delivery and filing of proofs of claim, consents, assignments or other instructions that Administrative Agent may require from time to time in order to prove or realize upon any rights or claims pertaining to Subordinated Debt or to effectuate the full benefit of the subordination contained herein) as may, in Administrative Agent’s sole and absolute discretion, be necessary or

107

desirable to assure the effectiveness of the subordination effected by this Agreement.

(h) (i) Each Bank that becomes a Junior Creditor understands and acknowledges by its execution hereof that each other Bank is entering into this Agreement and the other Loan Documents in reliance upon the absolute subordination in right of payment and in time of payment of Subordinated Debt to Senior Debt as set forth herein.

(ii) Only upon the Payment in Full of all Senior Debt shall any Junior Creditor be subrogated to any remaining rights of the Banks which are not Defaulting Banks to receive payments or distributions of assets of the Borrower made on or applicable to any Senior Debt.

(iii) Each Junior Creditor agrees that it will deliver all instruments or other writings evidencing any Subordinated Debt held by it to Administrative Agent, promptly after request therefor by the Administrative Agent.

(iv) No Junior Creditor may at any time sell, assign or otherwise transfer any Subordinated Debt, or any portion thereof, including, without limitation, the granting of any Lien thereon, unless and until satisfaction of the requirements of Section 9.6 above and the proposed transferee shall have assumed in writing the obligation of the Junior Creditor to the Banks under this Agreement, in a form acceptable to the Administrative Agent.

(v) If any of the Senior Debt should be invalidated, avoided or set aside, the subordination provided for herein nevertheless shall continue in full force and effect and, as between the Banks which are not Defaulting Banks and all Junior Creditors, shall be and be deemed to remain in full force and effect.

(vi) Each Junior Creditor hereby irrevocably waives, in respect of Subordinated Debt, all rights (x) under Sections 361 through 365, 502(e) and 509 of the Bankruptcy Code (or any similar sections hereafter in effect under any other Federal or state laws or legal or equitable principles relating to bankruptcy, insolvency, reorganizations, liquidations or otherwise for the relief of debtors or protection of creditors), and (y) to seek or obtain conversion to a different type of proceeding or to seek or obtain dismissal of a proceeding, in each case in relation to a bankruptcy, reorganization, insolvency or

108

other proceeding under similar laws with respect to the Borrower. Without limiting the generality of the foregoing, each Junior Creditor hereby specifically waives (A) the right to seek to give credit (secured or otherwise) to the Borrower in any way under Section 364 of the Bankruptcy Code unless the same is subordinated in all respects to Senior Debt in a manner acceptable to Administrative Agent in its sole and absolute discretion and (B) the right to receive any collateral security (including any “super priority” or equal or “priming” or replacement Lien) for any Subordinated Debt unless the Banks which are not Defaulting Banks have received a senior position acceptable to the Banks in their sole and absolute discretion to secure all Senior Debt (in the same collateral to the extent collateral is involved).

(i) (i) In addition to and not in limitation of the subordination effected by this Section 9.16, the Administrative Agent and each of the Banks which are not Defaulting Banks may in their respective sole and absolute discretion also exercise any and all other rights and remedies available at law or in equity in respect of a Defaulting Bank; and

(ii) The Administrative Agent shall give each of the Banks notice of the occurrence of a default under this Section 9.16 by a Defaulting Bank and if the Administrative Agent and/or one or more of the other Banks shall, at their option, fund any amounts required to be paid or advanced by a Defaulting Bank, the other Banks who have elected not to fund any portion of such amounts shall not be liable for any reimbursements to the Administrative Agent and/or to such other funding Banks.

(j) Notwithstanding anything to the contrary contained or implied herein, a Defaulting Bank shall not be entitled to vote on any matter as to which a vote by the Banks is required hereunder, including, without limitation, any actions or consents on the part of the Administrative Agent as to which the approval or consent of all the Banks or the Required Banks is required under Article VIII, Section 9.5 or elsewhere, so long as such Bank is a Defaulting Bank; provided, however, that in the case of any vote requiring the unanimous consent of the Banks, if all the Banks other than the Defaulting Bank shall have voted in accordance with each other, then the Defaulting Bank shall be deemed to have voted in accordance with such Banks.

109

(k) Each of the Administrative Agent and any one or more of the Banks which are not Defaulting Banks may, at their respective option, (i) advance to the Borrower such Bank’s Pro Rata Share of the Loans not advanced by a Defaulting Bank in accordance with the Loan Documents, or (ii) pay to the Administrative Agent such Bank’s Pro Rata Share of any costs, expenses or disbursements incurred or made by the Administrative Agent pursuant to the terms of this Agreement not theretofore paid by a Defaulting Bank. Immediately upon the making of any such advance by the Administrative Agent or any one of the Banks, such Bank’s Pro Rata Share and the Pro Rata Share of the Defaulting Bank shall be recalculated to reflect such advance. All payments, repayments and other disbursements of funds by the Administrative Agent to Banks shall thereupon and, at all times thereafter be made in accordance with such Bank’s recalculated Pro Rata Share unless and until a Defaulting Bank shall fully cure all defaults on the part of such Defaulting Bank under the Loan Documents or otherwise existing in respect of the Loans or this Agreement, at which time the Pro Rata Share of the Bank(s) which advanced sums on behalf of the Defaulting Bank and of the Defaulting Bank shall be restored to their original percentages.

SECTION 9.17 No Bankruptcy Proceedings. Each of the Borrower, the Banks and the Administrative Agent hereby agrees that it will not institute against any Designated Lender or join any other Person in instituting against any Designated Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under any federal or state bankruptcy or similar law, until the later to occur of (i) one year and one day after the payment in full of the latest maturing commercial paper note issued by such Designated Lender and (ii) the Maturity Date.

SECTION 9.18 Down REIT Guaranties.

(a) Notwithstanding any other provision hereof or of any other Loan Document to the contrary, the Administrative Agent, the Banks and Designated Lenders agree with Borrower that any funds, claims, or distributions actually received by the Administrative Agent for the account of any Bank or Designated Lender as a result of the enforcement of, or pursuant to, any Down REIT Guaranty, net of the Administrative Agent’s and the Banks’ expenses of collection thereof (such net amount, “Down REIT Guaranty Proceeds”), shall be made available for distribution equally and ratably (in proportion to the aggregate amount of

110

principal, interest and other amounts then owed in respect of the Obligations or of an issuance of Public Debt, as the case may be) among the Administrative Agent, the Banks and the Designated Lenders and the trustee or trustees of any Unsecured Debt, not subordinated to the Obligations (or to the holders thereof), issued by Borrower, before or after the Effective Date, in offerings registered under the Securities Act of 1933, as amended, or in transactions exempt from registration pursuant to rule 144A or Regulation 8 thereunder or listed on non-U.S. securities exchanges (“Public Debt”), and the Administrative Agent is hereby authorized by Borrower, by each Bank (on its own behalf and on behalf of its Designated Lender, if any) and by each Down REIT Guarantor by its execution and delivery of a Down REIT Guaranty, to make such Down REIT Guaranty Proceeds so available. No Bank or Designated Lender shall have any interest in any amount paid over by the Administrative Agent to the trustee or trustees in respect of any Public Debt (or to the holders thereof) pursuant to the foregoing authorization. This Section 9.18 shall apply solely to Down REIT Guaranty Proceeds, and not to any payments, funds, claims or distributions received by the Administrative Agent, any Bank or Designated Lender directly or indirectly from Borrower or any other Person other than from a Down REIT Guarantor pursuant to a Down REIT Guaranty. Borrower is aware of the terms of the Down REIT Guaranties, and specifically understands and agrees with the Administrative Agent, the Banks and the Designated Lenders that, to the extent Down REIT Guaranty Proceeds are distributed to holders of Public Debt or their respective trustees, such Down REIT Guarantor has agreed that the Obligations will not be deemed reduced by any such distributions and such Down REIT Guarantor shall continue to make payments pursuant to its Down REIT Guaranty until such time as the Obligations have been paid in full (and the Commitments have been terminated), after taking into account any such distributions of Down REIT Guaranty Proceeds in respect of Indebtedness other than the Obligations.

(b) Nothing contained herein shall be deemed (1) to limit, modify, or alter the rights of the Administrative Agent, the Banks and the Designated Lenders under any Down REIT Guaranty, (2) to subordinate the Obligations to any Public Debt, or (3) to give any holder of Public Debt (or any trustee for such holder) any rights of subrogation.

111

Agent, the Banks and the Designated Lenders and their respective successors and assigns. Nothing contained herein or in any Down REIT Guaranty shall be deemed for the benefit of any holder of Public Debt, or any trustee for such holder; nor shall anything contained herein or therein be construed to impose on the Administrative Agent, any Bank or any Designated Lender any fiduciary duties, obligations or responsibilities to the holders of any Public Debt or their trustees (including, but not limited to, any duty to pursue any Down REIT Guarantor for payment under its Down REIT Guaranty).

SECTION 9.19 USA PATRIOT Act Notice. Each Bank that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Bank) hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Bank or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.

SECTION 9.20 Public/Private Information. The Borrower hereby acknowledges that (a) the Administrative Agent will make available to the Banks materials and/or information provided by or on behalf of the Borrower hereunder (collectively, “Borrower Materials”) by posting the Borrower Materials on IntraLinks or another similar electronic system (the “Platform”) and (b) certain of the Banks may be “public-side” lenders (i.e., Banks that do not wish to receive material non-public information with respect to the Borrower or its securities) (each, a “Public Lender”). The Borrower hereby agrees that (w) all Borrower Materials that are to be made available to Public Lenders shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking Borrower Materials “PUBLIC”, the Borrower shall be deemed to have authorized the Administrative Agent and the Banks to treat such Borrower Materials as not containing any material non-public information with respect to the Borrower or its securities for purposes of United States Federal and state securities laws (provided, however, that to the extent such Borrower Materials constitute Information, they shall be

112

treated as set forth in Section 9.15); (y) all Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform marked “PUBLIC” or through a portion of the Platform designated “Public Investor;” and (z) the Administrative Agent shall be entitled to treat any Borrower Materials that are not marked “PUBLIC” as being suitable only for posting on a portion of the Platform not designated “Public Investor.”
