The Loans.

Advances. (a) Subject to the terms and conditions of this Agreement, each Lender severally agrees to make Loans to the Borrower from time to time during the Draw Period not to exceed an amount at any one time outstanding equal to the difference between such Lender’s Lender Commitment and the outstanding principal amount of such Lender’s Loans. Each such request for a Loan shall be deemed a request for a Loan from each Lender equal to such Lender’s Percentage of the aggregate amount so requested, and such aggregate amount shall be in an amount at least equal to $1,000,000.00 and equal to a multiple of $100,000.00, or the difference between the Commitment and the aggregate outstanding principal amount of all Loans, whichever is less. Each repayment of the Loans shall be deemed a repayment of each Lender’s Loans equal to such Lender’s Percentage of the amount so repaid. The obligations of the Lenders hereunder are several and not joint, and the preceding two sentences will give rise to certain inappropriate results if special provisions are not made to accommodate the failure of a Lender to fund a Loan as and when required by this Agreement; therefore, notwithstanding anything herein to the contrary, (A) no Lender shall be required to make Loans at any one time outstanding in excess of such Lender’s Percentage of the Commitment, and (B) if a Lender fails to make a Loan as and when required hereunder and Borrower subsequently makes a repayment on the Loans, such repayment shall be split among the non-defaulting Lenders ratably in accordance with their respective Percentages until each Lender has its Percentage of all of the outstanding Loans, and the balance of such repayment shall be divided among all of the Lenders in accordance with their respective Percentages. The Loans shall be evidenced by Notes substantially in the form of Exhibit C attached hereto. Anything contained herein to the contrary notwithstanding, any amounts repaid or prepaid for any reason in respect of the Loans may not be reborrowed.

(b) Borrower shall give the Agent notice of each borrowing of a Loan to be made hereunder as provided in Section 3.1, and the Agent shall deliver same to each Lender promptly thereafter. Not later than 12:00 noon (New York, New York time) on the date specified for each such borrowing of a Loan hereunder, each Lender shall make available the amount of the Loan, if any, to be made by it on such date to the Agent at the Agent’s principal office in New York, New York, in immediately available funds, for the account of Borrower. Such amounts received by the Agent will be held in Agent’s general ledger account. The amounts so received by the Agent shall, subject to the terms and conditions of this Agreement, be made available to the Borrower by wiring or otherwise transferring, in immediately available funds not later than 1:00 p.m., New York, New York time, such amount to an account designated by the Borrower and maintained with ▇▇▇▇▇ Fargo Bank, N.A. or any other account or accounts which the Borrower may from time to time designate to the Agent by a written notice as the account or accounts to which borrowings hereunder are to be wired or otherwise transferred.

Payments.

Except to the extent otherwise provided herein, all payments of principal, interest and other amounts to be made by Borrower hereunder, under the Notes and under the other Credit Documents shall be made in immediately available funds to the Agent at its principal office in New York, New York (or in the case of a successor Agent, at the principal office of such successor Agent in the United States), not later than 1:00 p.m., New York, New York time on the date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day).

The Borrower hereby unconditionally promises to pay to the Agent, for the account of each Lender, the then aggregate unpaid principal amount of the Loans on the Maturity Date.

The Borrower may, at its option, prepay the Loans, in whole or in part, without premium or penalty (other than any Funding Losses as provided below), at any time and from time to time by notifying the Agent in writing by 12:00 noon, New York, New York time, (i) on the proposed prepayment date in the case of Loans consisting of Base Rate Borrowings and (ii) at least two (2) Business Days prior to the proposed prepayment date in the case of Loans consisting of Eurodollar Rate Borrowings, in each case specifying the amount to be prepaid and the date of prepayment. Each such notice shall be irrevocable and the amount specified in such notice shall be due and payable on the date specified, together with accrued and unpaid interest to the date of such payment on the amount prepaid. Upon receipt of any such notice, the Agent shall promptly notify each Lender of the contents thereof. Partial prepayments of the Loans pursuant to this Section 2.2(c) shall be in an aggregate minimum principal amount of $5,000,000.00 or such amount plus a whole multiple of $1,000,000.00 in excess thereof, or, if less, the aggregate

outstanding principal balance of all Loans. The Borrower shall pay any Funding Losses resulting from any optional prepayment pursuant to this Section 2.2(c).

In the event, and on each occasion, that Net Offering Proceeds are received by the Parent or the Borrower in the form of cash, the Borrower shall (i) by 12:00 noon, New York, New York time, on the date that is one (1) Business Day after such Net Offering Proceeds are so received, deliver to the Agent a notice of the mandatory prepayment required pursuant to this Section 2.2(d), and (ii) on the date that is three (3) Business Days after such Net Offering Proceeds are so received, prepay the Loans in an aggregate principal amount equal to the lesser of (x) the aggregate amount of such Net Offering Proceeds so received in cash and (y) the aggregate outstanding principal amount of the Loans, in each case together with accrued and unpaid interest to the date of such payment on the amount prepaid. Upon receipt of any notice from the Borrower pursuant to the immediately preceding sentence, the Agent shall promptly notify each Lender of the contents thereof. If, and to the extent that, the aggregate outstanding principal amount of the Loans is less than the aggregate amount of such Net Offering Proceeds so received, the Commitment shall be reduced, on the date the mandatory prepayment under this Section 2.2(b) is required to be made, by an amount equal to the excess of the aggregate amount of such Net Offering Proceeds over the aggregate outstanding principal amount of the Loans, such reduction to be applied ratably to the Lender Commitment of each Lender based on its Percentage. The Borrower shall pay any Funding Losses resulting from any mandatory prepayment pursuant to this Section 2.2(d).

The Borrower may, at the time of making each payment hereunder, under any Note or under any other Credit Document, specify to the Agent the Loans or other amounts payable by the Borrower hereunder or thereunder to which such payment is to be applied (and in the event that it fails so to specify, such payment shall be applied to the Loans or, if no Loans are outstanding, to other amounts then due and payable, provided that if no Loans or other amounts are then due and payable or an Event of Default has occurred and is continuing, the Agent may apply such payment to the Obligations in such order as it may elect in its sole discretion, but subject to the other terms and conditions of this Agreement, including without limitation Section 2.3 hereof). Each payment received by the Agent hereunder, under any Note or under any other Credit Document for the account of a Lender shall be paid promptly to such Lender, in immediately available funds. If the Agent receives a payment for the account of a Lender prior to 1:00 p.m., New York, New York time, such payment must be delivered to the Lender on that same day and if it is not so delivered due to the fault of the Agent, the Agent shall pay to the Lender entitled to the payment the interest accrued on the amount of the payment pursuant to said Lender’s Note from the date the Agent receives the payment to the date the Lender received the payment.

If the due date of any payment hereunder or under any Note falls on a day which is not a Business Day or a Eurodollar Business Day, as the case may be, the due date for such payments shall be extended to the next succeeding Business Day or Eurodollar Business Day, respectively, and interest shall be payable for any principal so extended for the period of such extension; provided, however, that with respect to Eurodollar Rate Borrowings if such extension would cause the Eurodollar Business Day of payment to fall in another calendar month, the payment shall be due on the Eurodollar Business Day next preceding the due date of the payment.

All payments by the Borrower hereunder or under any other Credit Documents shall be made free and clear of and without deduction for or on account of any Taxes, including withholding and other charges of any nature whatsoever imposed by any taxing authority excluding in the case of each Lender taxes imposed on or measured by its net income or franchise taxes imposed in lieu of net income taxes by the jurisdiction in which it is organized or through which it acts for purposes of this Agreement. If any withholding or deduction from any payment to be made to, or for the account of, a Lender by the Borrower hereunder or under any other Credit Document is required in respect of any Taxes pursuant to any applicable law, rule, or regulation, then the Borrower will (i) pay to the relevant authority the full amount required to be so withheld or deducted; (ii) to the extent available, promptly forward to the Agent an official receipt or other documentation satisfactory to the Agent evidencing such payment to such authority; and (iii) pay to the Agent, for the account of each affected Lender, such additional amount or amounts as are necessary to ensure that the net amount actually received by such Lender will equal the full amount such Lender would have received had no such withholding or deduction been required. Each Lender shall determine such additional amount or amounts payable to it (which determination shall, in the absence of manifest error, be conclusive and binding on the Borrower). If a Lender becomes aware that any such withholding or deduction from any payment to be made by the Borrower hereunder or under any other Credit Document is required, then such Lender shall promptly notify the Agent and the Borrower thereof stating the reasons therefor and the

additional amount required to be paid under this Section. Each Lender shall execute and deliver to the Agent and Borrower such forms as it may be required to execute and deliver pursuant to subsection (h) below. To the extent that any such withholding or deduction results from the failure of a Lender to provide a form required by subsection (h) below (unless such failure is due to some prohibition under applicable Legal Requirements), the Borrower shall have no obligation to pay the additional amount required by clause (iii) above. Anything in this Section notwithstanding, if any Lender elects to require payment by the Borrower of any material amount under this Section, the Borrower may, within 60 days after the date of receiving notice thereof and so long as no Default shall have occurred and be continuing, elect to terminate such Lender as a party to this Agreement; provided that, concurrently with such termination the Borrower shall (1) if the Agent and each of the other Lenders shall consent, pay that Lender all principal, interest and fees and other amounts owed to such Lender through such date of termination or (2) have arranged for another institution approved by the Agent (such approval not to be unreasonably withheld) as of such date, to become a substitute Lender for all purposes under this Agreement in the manner provided in Section 9.5; provided further that, prior to substitution for any Lender, the Borrower shall have given written notice to the Agent of such intention and the Lenders shall have the option, but no obligation, for a period of 60 days after receipt of such notice, to increase their Commitments pro rata based on their Lender Commitments in order to replace the affected Lender in lieu of such substitution.

With respect to each Lender which is organized under the laws of a jurisdiction outside the United States, on the day of the initial borrowing from each such Lender hereunder and from time to time thereafter if requested by the Borrower or the Agent, such Lender shall provide the Agent and the Borrower with the forms prescribed by the Internal Revenue Service of the United States certifying as to such Lender’s status for purposes of determining exemption from United States withholding taxes with respect to all payments to be made to such Lender hereunder or other documents satisfactory to such Lender and the Agent indicating that all payments to be made to such Lender hereunder are not subject to United States withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty. Unless the Borrower and the Agent shall have received such forms or such documents indicating that payments hereunder are not subject to United States withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty, the Borrower or the Agent shall withhold taxes from such payments at the applicable statutory rate in the case of payments to or for any Lender organized under the laws of a jurisdiction outside the United States.

Pro Rata Treatment. Except to the extent otherwise provided herein: (a) each borrowing from the Lenders under Section 2.1(a) hereof shall be made ratably from the Lenders on the basis of their respective Percentages; (b) each payment of the Facility Fee shall be made for the account of the Lenders, and shall be applied, pro rata, according to the Lenders’ respective Lender Commitment; and (c) each payment by the Borrower of principal or interest on the Loans, of any other sums advanced by the Lenders pursuant to the Credit Documents, and of any other amount owed to the Lenders other than the Facility Fee, or any other sums designated by this Agreement as being owed to a particular Lender, shall be made to the Agent for the account of the Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans held by the Lenders.

Non-Receipt of Funds by the Agent. Unless the Agent shall have been notified by a Lender or the Borrower (the “Payor”) prior to the date on which such Lender is to make payment to the Agent of the proceeds of a Loan to be made by it hereunder or the Borrower is to make a payment to the Agent for the account of one or more of the Lenders, as the case may be (such payment being herein called the “Required Payment”), which notice shall be effective upon receipt, that the Payor does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient on such date and, if the Payor has not in fact made the Required Payment to the Agent, the recipient of such payment shall, on demand, pay to the Agent the amount made available by the Agent together with interest thereon in respect of the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to (a) the Base Rate for such period plus the Applicable Margin if the recipient returning a Required Payment is the Borrower, or (b) the Federal Funds Effective Rate for such period if the recipient returning a Required Payment is the Agent or a Lender.

Sharing of Payments, Etc. The Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers’ lien or counterclaim a Lender may otherwise have, each Lender shall be entitled, at its option, to offset balances held by it for the account of the Borrower at any of its offices, against any principal of or interest on

any of such Lender’s Loans to the Borrower hereunder, or other Obligations of the Borrower hereunder, which is not paid (regardless of whether such balances are then due to the Borrower), in which case it shall promptly notify the Borrower and the Agent thereof, provided that such Lender’s failure to give such notice shall not affect the validity thereof. If a Lender shall obtain payment of any principal of or interest on any Loan made by it under this Agreement, or other Obligation then due to such Lender hereunder, through the exercise of any right of set-off, banker’s lien, counterclaim or similar right, or otherwise, it shall promptly purchase from the other Lenders portions of the Loans made or other Obligations held by the other Lenders in such amounts, and make such other adjustments from time to time as shall be equitable to the end that all the Lenders shall share the benefit of such payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such benefit) pro rata in accordance with the unpaid principal and interest on the Obligations then due to each of them. To such end all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower.

Facility Fees. The Borrower shall pay a facility fee (the “Facility Fee”) to the Agent for the account of each Lender equal to the following percentage per annum multiplied by (i) during the Draw Period, the Commitment (as it may be reduced from time to time in accordance with this Agreement), and (ii) after the end of the Draw Period, the aggregate outstanding principal amount of all Loans, which will be in effect whenever and for so long as the Borrower has received the corresponding Credit Rating (the method of determining the Credit Rating based on multiple ratings to be the same as set forth and used to determine the Credit Rating for the definition of Applicable Margin):


CREDIT RATING	FACILITY FEE
A-/A3 or better		0.100	%
BBB+/Baa1		0.125	%
BBB/Baa2		0.150	%
BBB-/Baa3		0.200	%

If the Credit Rating is worse than BBB-/Baa3, or if there is no Credit Rating, then for that calendar quarter and for so long thereafter as the Credit Rating is worse than BBB-/Baa3 or if there is no Credit Rating, the Facility Fee will be equal to the daily unused amount of the Commitment multiplied by 0.250% per annum. The Facility Fee is payable in arrears on or before the tenth (10th) day of each January, April, July and October prior to termination or expiration of the Commitment, and on demand thereafter. The Facility Fee shall not be refundable (except as required by Section 3.1(c) of this Agreement). Any portion of the Facility Fee which is not paid by the Borrower when due shall bear interest at the Past Due Rate from the date due until the date paid by the Borrower. The Fee shall be calculated on the actual number of days elapsed in a year deemed to consist of 360 days.

Reduction of Commitment.

Unless previously terminated, the Commitment shall terminate at the end of the Draw Period.

The Borrower may from time to time reduce or terminate the Commitment; provided that (i) each reduction in the Commitment shall be a minimum of $50,000,000, and (ii) no reduction in the Commitment will be allowed if a Default is then in existence.

The Borrower shall notify the Agent of any election to reduce the Commitment under Section 2.7(b) at least two (2) Business Days prior to the effective date of such reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Agent shall advise the Lenders of the contents thereof. Each notice delivered pursuant to this Section shall be irrevocable. Any reduction of the Commitment shall be permanent. Each reduction in the Commitment shall be made ratably among the Lenders in accordance with their respective Lender Commitments.

Unless previously terminated, the Commitment shall be automatically reduced by the aggregate principal amount of any prepayment of the Loans.

Unless previously terminated, the Commitment shall be mandatorily reduced as, and to the extent, provided in Section 2.2 (d).

Any reduction of the Commitment pursuant to this Section 2.7 shall be permanent and shall be made ratably among the Lenders in accordance with their respective Lender Commitments.

Additional Guarantees. From time to time, certain of the direct or indirect owners of legal interests in the Borrower may request to guarantee collection of the unpaid balance of the Loans remaining after application of other recoveries against the Loans by the Agent and the Lenders. If the Borrower notifies the Agent of such a guarantee request and (a) supplies the Agent with the Organizational Documents of the proposed guarantor and any other information regarding the proposed guarantor as reasonably requested by the Agent or any of the Lenders, including any information that the Agent is required to obtain for any guarantor pursuant to applicable Legal Requirements, and (b) so long as the acceptance of the guarantee from the proposed guarantor does not violate any Legal Requirement applicable to the Agent or any of the Lenders, the Agent agrees, on behalf of the Lenders, to accept a guarantee from such proposed guarantor in the form attached hereto as Exhibit G.

All Loans. The obligation of any Lender to make any Loan is subject to the accuracy of all representations and warranties of the Borrower on the date of such Loan, to the performance by the Borrower of its obligations under the Credit Documents and to the satisfaction of the following further conditions: (a) the Agent shall have received the following, all of which shall be duly executed and in Proper Form: (1) a Request for Loan (i) by 12:00 noon, New York, New York time, one (1) Business Day before the date (which shall also be a Business Day) of the proposed Loan which is to be a Base Rate Borrowing, or (ii) by the Rate Designation Date of the proposed Loan which is to be a Eurodollar Rate Borrowing; and (2) such other documents as the Agent may reasonably require to satisfy itself or the request of any Lender; (b) no Default or Event of Default shall have occurred and be continuing; (c) the making of the Loan shall not be prohibited by any Legal Requirement (in which event the applicable portion of the Facility Fee will not be charged to the Borrower); (d) the Borrower shall have paid all legal fees and expenses of the type described in Section 5.10 hereof through the date of such Loan; and (e) the Agent shall have received an Officer’s Certificate certifying the information set forth therein as of the end of the immediately preceding fiscal quarter.

Unless a Request for Loan to the contrary is received as provided in this Agreement, each Eurodollar Rate Borrowing will convert to a Base Rate Borrowing after the expiration of the Interest Period.

Special Provisions Applicable to Eurodollar Rate Borrowings.

If the adoption of any applicable Legal Requirement or any change in any applicable Legal Requirement or in the interpretation or administration thereof by any Governmental Authority or compliance by the Lenders with any request or directive (whether or not having the force of law) of any central bank or other Governmental Authority shall at any time make it unlawful or impossible for any Lender to permit the establishment of or to maintain any Eurodollar Rate Borrowing, the commitment of the Lenders to establish or maintain such Eurodollar Rate Borrowing shall forthwith be suspended until such condition shall cease to exist and Borrower shall forthwith, upon demand by Agent to Borrower, (1) convert the Eurodollar Rate Borrowing with respect to which such demand was made to a Base Rate Borrowing; (2) pay all accrued and unpaid interest to date on the amount so converted; and (3) pay any amounts required to compensate the Lenders for any additional cost or expense which the Lenders may incur as a result of such adoption of or change in such Legal Requirement or in the interpretation or administration thereof and any Funding Loss which the Lenders may incur as a result of such conversion. If, when Agent so notifies Borrower pursuant to this Section 3.5(a) that an adoption of or change in Legal Requirements has occurred with the effects described herein, Borrower has given a Request for Loan specifying a Eurodollar Rate Borrowing but the selected Interest Period has not yet begun, such Request for Loan shall be deemed to be of no force and effect, as if never made, and the balance of the Loans specified in such Request for Loan shall bear interest at the Base Rate until a different available Interest Option shall be designated in accordance herewith.

	(1)		subject any Lender (or make it apparent that any Lender is subject) to any Taxes, or any deduction or withholding for any Taxes, on or from any payment due under any Eurodollar Rate Borrowing or other amount due hereunder, other than income and franchise taxes of the United States and its political subdivisions; or

	(2)		change the basis of taxation of payments due from Borrower to any Lender under any Eurodollar Rate Borrowing (otherwise than by a change in the rate of taxation of the overall net income of a Lender); or

	(3)		impose, modify, increase or deem applicable any reserve requirement (excluding that portion of any reserve requirement included in the calculation of the applicable interest rate), special deposit requirement or similar requirement (including, but not limited to, state law requirements and Regulation D) imposed, modified, increased or deemed applicable by any Governmental Authority against assets held by any Lender, or against deposits or accounts in or for the account of any Lender, or against loans made by any Lender, or against any other funds, obligations or other property owned or held by any Lender; or

	(4)		impose on any Lender any other condition regarding any Eurodollar Rate Borrowing;

and the result of any of the foregoing is to increase the cost to any Lender of agreeing to make or of making, renewing or maintaining such Eurodollar Rate Borrowing, or reduce the amount of principal or interest received by any Lender, then, upon demand by Agent, Borrower shall pay to such Lender, from time to time as specified by such Lender, additional amounts which shall compensate such Lender for such increased cost or reduced amount. Agent will promptly notify Borrower in writing of any event which will entitle any Lender to additional amounts pursuant to this paragraph. A Lender’s determination of the amount of any such increased cost, increased reserve requirement or reduced amount shall be prima facie evidence thereof. Borrower shall have the right, if it receives from Agent any notice referred to in this paragraph, upon three Business Days’ notice to Agent, either (i) to repay in full (but not in part) any borrowing with respect to which such notice was given, together with any accrued interest thereon, or (ii) to convert the Eurodollar Rate Borrowing which is the subject of the notice to a Base Rate Borrowing; provided, that any such repayment or conversion shall be accompanied by payment of (x) the amount required to compensate a Lender for the increased cost or reduced amount referred to in the preceding paragraph; (y) all accrued and unpaid interest to date on the amount so repaid or converted, and (z) any Funding Loss which any Lender may incur as a result of such repayment or conversion.

If for any reason with respect to any Interest Period Agent shall have determined (which determination shall be prima facie evidence thereof) that:

(1) Agent is unable through its customary general practices to determine any applicable Eurodollar Rate, or

(2) by reason of circumstances affecting the applicable market generally, Agent is not being offered deposits in United States dollars in such market, for the applicable Interest Period and in an amount equal to the amount of any applicable Eurodollar Rate Borrowing requested by Borrower, or

(3) any applicable Eurodollar Rate will not adequately and fairly reflect the cost to the Lenders of making and maintaining such Eurodollar Rate Borrowing hereunder for any proposed Interest Period,

then Agent shall give Borrower notice thereof and thereupon, (A) any Request for Loan previously given by Borrower designating the applicable Eurodollar Rate Borrowing which has not commenced as of the date of such notice from Agent shall be deemed for all purposes hereof to be of no force and effect, as if never given, and (B) until Agent shall notify Borrower that the circumstances giving rise to such notice from Agent no longer exist, each Request for Loan requesting the applicable Eurodollar Rate shall be deemed a request for a Base Rate Borrowing, and any applicable Eurodollar Rate Borrowing then outstanding shall be converted, without any notice to or from Borrower, upon the termination of the Interest Period then in effect with respect to it, to a Base Rate Borrowing.

Borrower shall indemnify the Agent and each Lender against and hold the Agent and each Lender harmless from any Funding Loss. The indemnification in this Section 3.5(d) shall survive the payment of the Notes. A certificate as to any additional amounts payable pursuant to this subsection and setting forth the reasons for the Funding Loss submitted by Agent to Borrower shall be prima facie evidence thereof.

The Borrower shall pay to the Agent or a Lender the Eurodollar Reserve Requirement incurred by that Lender within thirty (30) days after written demand by Agent to the Borrower. The demand setting forth the Eurodollar Reserve Requirement shall be prima facie evidence thereof.

Funding Offices; Adjustments Automatic. Any Lender may, if it so elects, fulfill its obligation as to any Eurodollar Rate Borrowing by causing a branch or affiliate of such Lender to make such Loan and may transfer and carry such Loan at, to, or for the account of, any branch office or affiliate of such Lender; provided, that in such event for the purposes of this Agreement such Loan shall be deemed to have been made by such Lender and the obligation of Borrower to repay such Loan shall nevertheless be to such Lender and shall be deemed held by it for the account of such branch or affiliate. Without notice to Borrower or any other person or entity, each rate required to be calculated or determined under this Agreement shall automatically fluctuate upward and downward in accordance with the provisions of this Agreement.

Funding Sources, Payment Obligations. Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled to fund and maintain its funding of all or any part of the Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Lender had actually funded and maintained each Eurodollar Rate Borrowing during each Interest Period through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the interest rate for such Interest Period. Notwithstanding the foregoing, Funding Losses, increased costs and other obligations relating to Eurodollar Rate Borrowings described in Section 3.5 of this Agreement will only be paid by the Borrower as and when actually incurred by the Lenders.

Mitigation, Non-Discrimination. Each Lender will notify the Borrower through the Agent of any event occurring after the date of this Agreement which will require or enable such Lender to take the actions described in Sections 3.5(a) or (b) of this Agreement as promptly as practicable after it obtains knowledge thereof and determines to request such action, and (if so requested by the Borrower through the Agent) will designate a different lending office of such Lender for the applicable Eurodollar Rate Borrowing or will take such other action as the Borrower reasonably requests if such designation or action is consistent with the internal policy of such Lender and legal and regulatory restrictions, can be undertaken at no additional cost, will avoid the need for, or reduce the amount of, such action and will not, in the sole opinion of such Lender, be disadvantageous to such Lender (provided that such Lender will have no obligation to designate a different lending office which is located in the United States of America).

None of the Lenders shall be able to pass through to the Borrower changes and costs under Section 3.5 of this Agreement on a discriminating basis, such that such changes and costs are not also passed through by each Lender to other customers of such Lender similarly situated where such customer is subject to documents providing for such pass through.

If any Lender elects under Section 3.5 of this Agreement to suspend or terminate the availability of Eurodollar Rate Borrowings for any material period of time, and the event giving rise to such election is not generally applicable to all of the Lenders, the Borrower may within sixty (60) days after notification of such Lender’s election, and so long as no Event of Default is then in existence, either (i) demand that such Lender, and upon such demand, such Lender shall promptly, assign its Lender Commitment to another financial institution subject to and in accordance with the provisions of Section 9.5 of this Agreement for a purchase price equal to the unpaid balance of principal, accrued interest, the unpaid balance of the Facility Fee and expenses owing to such Lender pursuant to this Agreement, or (ii) pay such Lender the unpaid balance of principal, accrued interest, the unpaid balance of the Facility Fee and expenses owing to such Lender pursuant to this Agreement, whereupon, such Lender shall no longer be a party to this Agreement or have any rights or obligations hereunder or under any other Credit Documents, and the Commitment shall immediately and permanently be reduced by an amount equal to the Lender Commitment of such Lender.

All necessary permits, registrations and consents for such making and performance have been obtained except where the lack thereof could not reasonably be expected to have a Material Adverse Effect.

Other Debt. The Borrower is not in default in the payment of any other Indebtedness or under any agreement, mortgage, deed of trust, security agreement or lease to which it is a party which default could reasonably be expected to have a Material Adverse Effect.

Litigation. There is no litigation or administrative proceeding pending or, to the knowledge of the Borrower, threatened against, or any outstanding judgment, order or decree affecting, the Borrower before or by any Governmental Authority which is not adequately covered by insurance or which, if determined adversely to the Borrower could reasonably be expected to have a Material Adverse Effect. The Borrower is not in default with respect to any judgment, order or decree of any Governmental Authority which default could reasonably be expected to have a Material Adverse Effect.

Taxes. The Borrower has filed all tax returns required to have been filed and paid all taxes shown thereon to be due, except those for which extensions have been obtained, those which are being contested in good faith and those for which the Borrower’s failure to file a return or pay could not reasonably be expected to have a Material Adverse Effect.

Regulation U. None of the proceeds of any Loan or Letter of Credit will be used for the purpose of purchasing or carrying directly or indirectly any margin stock or for any other purpose that would constitute this transaction a “purpose credit” within the meaning of Regulation U of the Board of Governors of the Federal Reserve System.

Securities Act of 1933. Other than the Agent’s efforts in syndicating the Loans (for which the Agent is responsible) neither the Borrower nor any agent acting for it has offered the Notes or any similar obligation of the Borrower for sale to or solicited any offers to buy the Notes or any similar obligation of the Borrower from any

Person other than the Agent or any Lender, and neither the Borrower nor any agent acting for it will take any action which would subject the sale of the Note to the provisions of Section 5 of the Securities Act of 1933, as amended.

Notwithstanding the foregoing, the Borrower shall not be charged with any cost or expense incurred by the Agent or any Lender relating to disputes or claims among or between the Agent, the Lenders, or any of them unless during the continuance of an Event of Default and related to details of enforcement of the Lenders’ rights under the Credit Documents.

Borrower’s Performance. If the Borrower should fail to comply with any of the agreements, covenants or obligations of the Borrower under this Agreement or any other Credit Document which requires the payment of money, then the Agent (in the Borrower’s name or in Agent’s name) may, if such payment has not been made within ten (10) days after written request from Agent and after expiration of any grace or cure periods provided in any Credit Document, perform or cause to be performed such agreement, covenant or obligation, for the account of the Borrower and at the Borrower’s sole expense, but shall not be obligated to do so. Any and all reasonable expenses thus incurred or paid by the Agent and by any Lender shall be the Borrower’s demand obligations to the Agent or such Lender and shall bear interest from the date of demand therefor until the date that the Borrower repays it to the Agent or the applicable Lender at the Past Due Rate. Upon making any such payment or incurring any such expense, the Agent or the applicable Lender shall be fully subrogated to all of the rights of the Person receiving such payment. Any amounts owing by the Borrower to the Agent or any Lender pursuant to this provision or any other provision of this Agreement shall automatically and without notice be secured by collateral, if any, provided by the Credit Documents.

Professional Services. Promptly upon the Agent’s request to satisfy itself or the request of any Lender, the Borrower shall: (a) allow an inspection and/or appraisal of the Borrower’s Property to be made by a Person approved by the Agent in its sole discretion; and (b) if the Agent believes that an Event of Default has occurred or is about to occur, cause to be conducted or prepared any other written report, summary, opinion, inspection, review, survey, audit or other professional service relating to the Borrower’s Property or any operations in connection with it (all as designated in the Agent’s request), including, without limitation, any accounting, auctioneering, architectural,

consulting, engineering, design, legal, management, pest control, surveying, title abstracting or other technical, managerial or professional service relating to such property or its operations. So long as no Event of Default has occurred and is continuing, the foregoing shall not be at the Borrower’s expense.

Capital Adequacy.

If after the date of this Agreement, the Agent or any Lender shall have determined that the adoption or effectiveness of any applicable law, rule or regulation regarding capital adequacy of general applicability, or any change therein, 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 the Agent or any Lender with any request or directive regarding capital adequacy of general applicability (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on the Agent’s or any Lender’s capital as a consequence of its obligations hereunder to a level below that which the Agent or such Lender could have achieved but for such adoption, change or compliance (taking into consideration the Agent’s or such Lender’s policies with respect to capital adequacy) by an amount deemed by the Agent or such Lender to be material, then from time to time, the Borrower shall pay to the Agent or such Lender such additional amount or amounts as will compensate the Agent or such Lender for such reduction.

A certificate of the Agent or such Lender setting forth such amount or amounts as shall be necessary to compensate the Agent or such Lender as specified in Section 5.14(a) hereof and making reference to the applicable law, rule or regulation shall be delivered as soon as practicable to the Borrower and shall be prima facie evidence thereof. The Borrower shall pay the Agent or such Lender the amount shown as due on any such certificate within fourteen (14) Business Days after the Agent or such Lender delivers such certificate. In preparing such certificate, the Agent or such Lender may employ such assumptions and allocations of costs and expenses as it shall in good ▇▇▇▇▇ ▇▇▇▇ reasonable and may use any reasonable averaging and attribution method.

Property Pool.

The Borrower (or a Subsidiary of the Borrower or a Subsidiary of a QRS Entity if the conditions in clause (b) below are satisfied) will at all times own fee simple title to a pool (the “Pool”) of Real Property that is not subject to any Lien other than Permitted Encumbrances (the “Pool Real Estate”) and except as permitted by Section 6.5, and is not subject to or affected by any Limiting Agreement except as permitted by Section 6.5, with an aggregate Pool Value of at least one hundred fifty percent (150%) of the Borrower’s Indebtedness other than Secured Debt outstanding from time to time.

If requested by the Agent, the Borrower will provide to the Agent written assessments from third party independent environmental consultants for all Pool Real Estate acquired after the date of this Agreement. If Super Majority Lenders determine that there are material environmental conditions existing on or risks to such properties, the properties will be excluded from the Pool.

Notwithstanding the foregoing, (i) the maximum Pool Value that can be attributable to the Value of land not improved for multifamily use (not including land that is either under development for multifamily use or planned for commencement of development for multifamily use within three (3) years after the date of acquisition) is five percent (5%) of the Pool Value after adding the effect of said land; and (ii) the maximum Pool Value that can be attributable to the Value (in the aggregate) of Real Property that is under construction or development, that has not reached the Calculation Date, that has reached the Calculation Date but the Occupancy Level is less than eighty percent (80%), unimproved land that is planned for commencement of development within three (3) years after the date of acquisition, and land not improved for multifamily use, is twenty-five percent (25%) of the Pool Value after adding the effect of said Real Property and land.

If any Pool Real Estate is owned by a Subsidiary of the Borrower or of a QRS Entity, then it may be included in the Pool only if:

the owner of the Pool Real Estate is either (1) a wholly owned Subsidiary of the Borrower or of a QRS Entity or (2) if not a wholly owned Subsidiary of the Borrower or of a QRS Entity, then (x) the value of the Pool Real Estate owned by such Subsidiary (“Partial Subsidiary Real Estate”) to be used in the calculation in clause (a) above shall be as provided in clause (a) multiplied by the cumulative percentage interest of the Subsidiary legally owned by the Borrower or such QRS Entity, as the case may be, and (y) the Borrower or such QRS Entity, as the case may be controls the right to create a Lien on the Partial Subsidiary Real Estate to secure the Borrower’s Indebtedness, and to sell, transfer or otherwise dispose of the Partial Subsidiary Real Estate;

the owner of the Pool Real Estate (1) has no Indebtedness other than Non-recourse Debt, and other than Indebtedness to the Borrower subordinated to the Indebtedness incurred under this Agreement on terms satisfactory to the Agent; and (2) would not at any time be in default of Sections 7.1(g), (h), (i), (j), or (k), if said subsections were applicable to said owner; and

the indicia of ownership of the Subsidiary of the Borrower (or of its owners if not a direct Subsidiary of the Borrower) or of the QRS Entity is not subject to a Lien (other than Permitted Encumbrances).

DC Holdings. The Borrower shall maintain at least 99.5% aggregate ownership of the indicia of ownership of each DC Holdings Entity, and shall maintain management and control of each DC Holdings Entity.

Negative Covenants.

The Borrower covenants and agrees with the Agent and the Lenders that prior to the termination of this Agreement it will not do any of the following:

Mergers, Consolidations and Acquisitions of Assets. In any single transaction or series of related transactions, directly or indirectly: (a) liquidate or dissolve; (b) be a party to any merger or consolidation other than a merger or consolidation in which (i) the Borrower is the surviving entity after such merger or consolidation, or (ii) the individuals constituting the Borrower’s Board of Trustees immediately prior to such merger or consolidation represent a majority of the surviving entity’s Board of Directors or Board of Trustees after such merger or consolidation; or (c) sell, convey or lease all or substantially all of its assets.

Redemption. At any time redeem, retire or otherwise acquire, directly or indirectly, any shares of its capital stock if such action would cause the Borrower to not be in compliance with this Agreement.

Nature of Business. Change its primary business, which is and will be the ownership, operation, development and redevelopment of multi-family residential properties, and may include other business initiatives, investments and activities which are related, but incidental, to Borrower’s primary business; provided, however, that the aggregate value of the specific loans and investments described below (“Specified Permitted Holdings”) shall not at any time exceed thirty percent (30%) of the Total Asset Value after giving effect to the Specified Permitted Holdings. “Specified Permitted Holdings” shall mean the following: securities received in settlement of liabilities created in the ordinary course of business;

investments in Unconsolidated Affiliates that are engaged primarily in Borrower’s primary business as described in this Section;

loans, advances, and extensions of credit to Persons (who are not Affiliates of the Borrower);

investments in Persons not included in any other Specified Permitted Holdings;

investments in income producing Real Property that is not primarily multifamily residential property (property will be considered as primarily multifamily residential property even if it includes other non-primary uses which are incidental to the residential use, such as retail or office);

investments in land not improved for multifamily use (not including land that is either under development or planned for commencement of development within three (3) years after the date of acquisition); and

investments of any kind not included in any other Specified Permitted Holdings and which are not incidental to Borrower’s primary business as described in this Section.

Transactions with Related Parties. Enter into any transaction or agreement with any officer, director, or holder of more than five percent (5%) (based on voting rights) of the issued and outstanding capital stock of the Borrower (or any Affiliate of the Borrower), unless the same is upon terms substantially similar to those obtainable from qualified wholly unrelated sources, and, if such transaction or series of related transactions has a value in excess of $10,000,000.00, is approved by the majority of the Borrower’s non-interested trustees.

Limiting Agreements. Neither Borrower nor any of its Subsidiaries has entered into, and after the date hereof, neither Borrower nor any of its Subsidiaries shall enter into, any Limiting Agreements; provided that so long as the Borrower has received a Credit Rating from two of Standard & Poor’s Rating Services, ▇▇▇▇▇’▇ Investors Service, Inc. or Fitch equal to a Credit Rating from Fitch that is BBB or better, an S&P Rating that is BBB or better or a ▇▇▇▇▇’▇ Rating that is Baa2 or better, up to five percent (5%) of the Pool Value (after adding the effect of said property) may be subject to debt-related agreements (but not the related mortgages or pledges) that require the owner of the project to mortgage and pledge the project to secure Indebtedness if any of the Borrower’s Credit Ratings are below BBB-/Baa3, or the equivalent.

Parent Negative Covenants. The Parent will not (a) have any Subsidiary that is a “qualified REIT subsidiary” under Section 856 of the Code other than the QRS Entities; (b) own any Property other than the ownership interests of the Borrower, and the Parent’s ownership interests as of October 31, 2001 in the QRS Entities; (c) give or allow any Lien on any of its Property including the ownership interests of the Borrower; and (d) except for the Guaranty, create, incur, suffer or permit to exist, or assume or guarantee, directly or indirectly, contingently or otherwise, or become or remain liable with respect to (i) any Indebtedness if the aggregate of such Indebtedness and the Indebtedness of the Borrower would violate Sections 5.3(a), (b), or (c) if such aggregate Indebtedness is treated as the Borrower’s Indebtedness, and (ii) any Indebtedness of a Person other than the Parent.

Events of Default and Remedies.

Events of Default. If any of the following events shall occur, then, as to the events described in Sections 7.1(b), (c), and (d), if the event has not been waived, cured or remedied within twenty (20) days after the Agent gives the Borrower notice of such event, at any time thereafter, and as to all of the other events described herein, at any time, the Agent may do any or all of the following: (1) without notice to the Borrower, declare the Notes to be, and thereupon the Notes shall forthwith become, immediately due and payable, together with all accrued interest thereon, without notice of any kind, notice of acceleration or of intention to accelerate, presentment and demand or protest, all of which are hereby expressly waived; (2) without notice to the Borrower, terminate the Commitment; (3) exercise, as may any other Lender, its rights of offset against each account and all other Property of the Borrower in the possession of the Agent or any such Lender, which right is hereby granted by the Borrower to the Agent and each Lender; and (4) exercise any and all other rights pursuant to the Credit Documents:

The Borrower shall fail to pay or prepay any principal of or interest on the Notes or any fee or any other obligation hereunder within five (5) days after it was due; or

The Borrower or the Parent shall fail to pay when due (whether on the scheduled maturity date or otherwise), or within any applicable period of grace, any principal of or interest on any other Indebtedness, other than Disqualified Stock, in excess of $50,000,000.00 in principal amount; or

Any written representation or warranty made in any Credit Document by or on behalf of the Borrower, when taken as a whole shall prove to have been incorrect, false or misleading in any material respect; or

Default shall occur in the punctual and complete performance of any covenant of the Borrower or any other Person other than the Agent or the Lenders contained in any Credit Document not specifically set forth in this Section; or

A final judgment or judgments in the aggregate for the payment of money in excess of $50,000,000.00 shall be rendered against the Borrower or the Parent (other than any judgment as to which, and only to the extent, an insurance company having a rating of “A-” or better by A.M. Best Co. in Best’s Rating Guide, has acknowledged coverage of such claim in writing), and the same shall remain undischarged for a period of thirty (30) days during which execution shall not be effectively stayed; or

The Borrower shall not be in compliance with any provision of Section 6.3 during the period covered by an Officer’s Certificate and such non-compliance remains in existence on the date the next Officer’s Certificate is required to be presented to the Agent under Section 5.2(c) of this Agreement; provided, however, that such right to defer compliance shall be available to the Borrower for each such provision no more than once every twelve (12) months; or

Any order shall be entered in any proceeding against the Borrower or the Parent decreeing the dissolution, liquidation or split-up thereof, and such order shall remain in effect for more than thirty (30) days; or

The Borrower or the Parent shall make a general assignment for the benefit of creditors or shall petition or apply to any tribunal for the appointment of a trustee, custodian, receiver or liquidator of all or any substantial part of its business, estate or assets or shall commence any proceeding under any bankruptcy, reorganization, arrangement, insolvency, readjustment of debt, dissolution or liquidation law of any jurisdiction, whether now or hereafter in effect; or

Any such petition or application shall be filed or any such proceeding shall be commenced against the Borrower or the Parent and the Borrower or the Parent by any act or omission shall indicate approval thereof, consent thereto or acquiescence therein, or an order shall be entered appointing a trustee, custodian, receiver or liquidator of all or any substantial part of the assets of such Person or granting relief to such Person or approving the petition in any such proceeding, and such order shall remain in effect for more than ninety (90) days; or

The Borrower or the Parent shall fail generally to pay its debts as they become due or suffer any writ of attachment or execution or any similar process to be issued or levied against it or any substantial part of its Property which is not released, stayed, bonded or vacated within thirty (30) days after its issue or levy; or

The Borrower or the Parent shall have concealed, removed, or permitted to be concealed or removed, any part of its Property, with intent to hinder, delay or defraud its creditors or any of them, or made or suffered a transfer of any of its Property which may be fraudulent under any bankruptcy, fraudulent conveyance or similar law; or shall have made any transfer of its Property to or for the benefit of a creditor at a time when other creditors similarly situated have not been paid.

Remedies Cumulative. No remedy, right or power conferred upon the Agent or the Lenders is intended to be exclusive of any other remedy, right or power given hereunder or now or hereafter existing at law, in equity, or otherwise, and all such remedies, rights and powers shall be cumulative.

Guaranty Proceeds.

Notwithstanding any other provision of any Credit Document to the contrary, any funds, claims, or distributions actually received by Agent for the account of any Lender as a result of the enforcement of, or pursuant to, the Guaranty, net of Agent’s and Lenders’ expenses of collection thereof (such net amount, “Guaranty Proceeds”), shall be made available for distribution equally and ratably (in proportion to the aggregate amount of principal, interest and other amounts then owed in respect of the Obligations or of an issuance of Public Debt (as defined below), as the case may be) among the Agent, the Lenders and the trustee or trustees of any Indebtedness not subordinated to the Obligations (or to the holders thereof), issued by Borrower, before or after the date of this Agreement, in offerings registered under the Securities Act of 1933, as amended, or in transactions exempt from

registration pursuant to rule 144A thereof (“Public Debt”). Agent is hereby authorized by Borrower, by each Lender and by the Parent (by its execution and delivery of the Guaranty) to make such Guaranty Proceeds so available. No Lender shall have any interest in any amount paid over by Agent to the trustee or trustees in respect of any Public Debt (or to the holders thereof) pursuant to the foregoing authorization. This Section 7.3(a) shall apply (i) solely to Guaranty Proceeds and not to any payments, funds, claims or distributions received by Agent or Lenders directly or indirectly from Borrower or any other Person other than from the Parent pursuant to the Guaranty, and (ii) as to Public Debt issued after December 20, 2000, only if the documents governing the Public Debt provide for the same sharing with the Lenders of guaranty proceeds recovered to pay the Public Debt. Borrower is aware of the terms of the Guaranty, and specifically understands and agrees with Agent and the Lenders that, to the extent Guaranty Proceeds are distributed to holders of Public Debt or their respective trustees, the Parent has agreed that the Obligations will not be deemed reduced by any such distributions, and the Parent shall continue to make payments pursuant to the Guaranty until such times as the Obligations have been paid in full (and the Commitment has been terminated and any LC Exposure reduced to zero), after taking into account any such distributions of Guaranty Proceeds in respect of Indebtedness other than the Obligations.

Nothing contained herein shall be deemed (i) to limit, modify, or alter the rights of Agent and Lenders under the Guaranty, (ii) to subordinate the Obligations to any Public Debt, or (iii) to give any holder of Public Debt (or any trustee for such holder) any rights of subrogation.

This Agreement and the Guaranty are for the sole benefit of Agent and the Lenders and their respective successors and assigns. Nothing contained herein or in the 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 Agent or Lenders any fiduciary duties, obligations or responsibilities to the holder of any Public Debt or their trustees (including, but not limited to, any duty to pursue the Parent for payment under the Guaranty).

The Agent.

Appointment, Powers and Immunities.

Each Lender hereby irrevocably appoints and authorizes the Agent to act as its agent hereunder and under the other Credit Documents with such powers as are specifically delegated to the Agent by the terms hereof and thereof, together with such other powers as are reasonably incidental thereto. The Agent (i) shall not have any duties or responsibilities except those expressly set forth in this Agreement and the other Credit Documents, and shall not by reason of this Agreement or any other Credit Document be a trustee for any Lender; (ii) shall not be responsible to any Lender for any recitals, statements, representations or warranties contained in this Agreement or any other Credit Document, or in any certificate or other document referred to or provided for in, or received by any of them under, this Agreement or any other Credit Document, or for the value, validity, effectiveness, genuineness, enforceability, execution, filing, registration, collectibility, recording, perfection, existence or sufficiency of this Agreement or any other Credit Document or any other document referred to or provided for herein or therein or any property covered thereby or for any failure by any Party or any other Person to perform any of its obligations hereunder or thereunder, and shall not have any duty to inquire into or pass upon any of the foregoing matters; (iii) shall not be required to initiate or conduct any litigation or collection proceedings hereunder or any other Credit Document except to the extent requested by the Majority Lenders; (iv) SHALL NOT BE RESPONSIBLE FOR ANY MISTAKE OF LAW OR FACT OR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY IT HEREUNDER OR UNDER ANY OTHER CREDIT DOCUMENT OR ANY OTHER DOCUMENT OR INSTRUMENT REFERRED TO OR PROVIDED FOR HEREIN OR THEREIN OR IN CONNECTION HEREWITH OR THEREWITH, INCLUDING, WITHOUT LIMITATION, PURSUANT TO ITS OWN NEGLIGENCE, BUT NOT INCLUDING AND EXCEPT FOR THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT; (v) shall not be bound by or obliged to recognize any agreement among or between the Borrower, the Agent, and any Lender other than this Agreement and the other Credit Documents, regardless of whether the Agent has knowledge of the existence of any such agreement or the terms and provisions thereof; (vi) shall not be charged with notice or knowledge of any fact or information not herein set out or provided to the Agent in accordance with the terms of this Agreement or any other Credit Document; (vii) shall not be responsible for any delay, error, omission or default of any mail, telegraph, cable or wireless agency or operator, and (viii) shall not be responsible for the acts or edicts of any Governmental Authority. The Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care.

Without the prior written consent of Agent and all of the Lenders, Agent shall not (i) modify or amend in any respect whatsoever the interest rate provisions of the Credit Documents, (ii) increase the Commitment, (iii) extend the Maturity Date, (iv) extend or reduce the due date for, or change the amount of, the scheduled payments of principal or interest on the Loans, the LC Disbursements or the fees set forth in Section 2.6, (v) amend the definitions of Majority Lenders or Super Majority Lenders or any requirement that certain actions be taken only with the consent of a certain number of the Lenders, (vi) amend or waive any provisions of Section 5.15 of this Agreement, or (vii) release the Parent from the Guaranty. From time to time upon Agent’s request, each Lender shall execute and deliver such documents and instruments as may be reasonably necessary to enable Agent to effectively administer and service the Loan in its capacity as lead lender and servicer and in the manner contemplated by the provisions of this Agreement.

Without the prior written consent of the Majority Lenders, Agent shall not modify, amend or waive in any respect whatsoever the provisions of (i) Section 5.3 or the definitions of the financial covenants (or any component thereof) described in Section 5.3, (ii) Section 5.11(c)(i), or (iii) Section 6.1.

All information provided to the Agent under or pursuant to the Credit Documents, and all rights of the Agent to receive or request information, or to inspect information or Property, shall be by the Agent on behalf of the Lenders. If any Lender requests that it be able to receive or request such information, or make such inspections, in its own right rather than through the Agent, the Borrower will cooperate with the Agent and such Lender in order to obtain such information or make such inspection as such Lender may reasonably require.

The Borrower shall be entitled to rely upon a written notice or a written response from the Agent as being pursuant to concurrence or consent of the Majority Lenders unless otherwise expressly stated in the Agent’s notice or response.

Reliance. The Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by telephone, telex, facsimile, telegram or cable) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (which may be counsel for the Borrower), independent accountants and other experts selected by the Agent. The Agent shall not be required in any way to determine the identity or authority of any Person delivering or executing the same. As to any matters not expressly provided for by this Agreement or any other Credit Document, the Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and thereunder in accordance with instructions of the Majority Lenders, and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. If any order, writ, judgment or decree shall be made or entered by any court affecting the rights, duties and obligations of the Agent under this Agreement or any other Credit Document, then and in any of such events the Agent is authorized, in its sole discretion, to rely upon and comply with such order, writ, judgment or decree which it is advised by legal counsel of its own choosing is binding upon it under the terms of this Agreement, the relevant Credit Document or otherwise; and if the Agent complies with any such order, writ, judgment or decree, then it shall not be liable to any Lender or to any other Person by reason of such compliance even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated.

Defaults. The Agent shall not be deemed to have constructive knowledge of the occurrence of a Default (other than the non-payment of principal of or interest on Loans) unless it has received notice from a Lender or the Borrower specifying such Default and stating that such notice is a “Notice of Default”. In the event that the Agent receives such a notice of the occurrence of a Default, or whenever the Agent has actual knowledge of the occurrence of a Default, the Agent shall give prompt written notice thereof to the Lenders (and shall give each Lender prompt notice of each such non-payment). The Agent shall (subject to Section 8.7 hereof) take such action with respect to such Default as shall be directed by the Majority Lenders and within its rights under the Credit Documents and at law or in equity, provided that, unless and until the Agent shall have received such directions, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, permitted hereby with respect to such Default as it shall deem advisable in the best interests of the Lenders and within its rights under the Credit Documents in order to preserve, protect or enhance the collectibility of the Loans, at law or in equity.

Rights as a Lender. With respect to the Commitment and the Loans made, Agent, in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the same

as though it were not acting in its agency capacity, and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent may (without having to account therefor to any other Lender) as a Lender, and to the same extent as any other Lender, accept deposits from, lend money to and generally engage in any kind of banking, trust, letter of credit, agency or other business with the Borrower (and any of its Affiliates) as if it were not acting as the Agent but solely as a Lender. The Agent may accept fees and other consideration from the Borrower (in addition to the fees heretofore agreed to between the Borrower and the Agent) for services in connection with this Agreement or otherwise without having to account for the same to the Lenders.

Indemnification. The Lenders agree to indemnify the Agent, its officers, directors, agents and Affiliates, ratably in accordance with each Lender’s respective Percentage, for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of this Agreement or any other Credit Document or any other documents contemplated by or referred to herein or therein, or the transactions contemplated hereby or thereby (including, without limitation, interest, penalties, reasonable attorneys’ fees and amounts paid in settlement in accordance with the terms of this Section 8, but excluding, unless a Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its agency duties hereunder) or the enforcement of any of the terms hereof or thereof or of any such other documents, provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the party to be indemnified, or from the Agent’s default in the express obligations of the Agent to the Lenders provided for in this Agreement. The obligations of the Lenders under this Section 8.5 shall survive the termination of this Agreement and the repayment of the Obligations.

Non-Reliance on Agent and Other Lenders. Each Lender agrees that it has received current financial information with respect to the Borrower and that it has, independently and without reliance on the Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Borrower and decision to enter into this Agreement and that it will, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement or any of the other Credit Documents. The Agent shall not be required to keep itself informed as to the performance or observance by any Party of this Agreement or any of the other Credit Documents or any other document referred to or provided for herein or therein or to inspect the properties or books of the Borrower or any Party except as specifically required by the Credit Documents. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Agent hereunder or the other Credit Documents, the Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower or any other Party (or any of their affiliates) which may come into the possession of the Agent. Each Lender assumes all risk of loss in connection with its Percentage in the Loans to the full extent of its Percentage therein. The Agent assumes all risk of loss in connection with its Percentage in the Loans to the full extent of its Percentage therein.

Failure to Act. Except for action expressly required of the Agent, as the case may be, hereunder, or under the other Credit Documents, the Agent shall in all cases be fully justified in failing or refusing to act hereunder and thereunder unless it shall receive further assurances to its satisfaction by the Lenders of their indemnification obligations under Section 8.5 hereof against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.

Resignation of Agent. Subject to the appointment and acceptance of a successor Agent as provided below, the Agent may resign at any time by giving notice thereof to the Lenders and the Borrower. The Agent shall resign if it has assigned all of its Lender Commitment and Loans and is not an Issuing Bank. Upon any such resignation, (i) the Majority Lenders with the consent of the Borrower, so long as no Default is in existence, shall have the right to appoint a successor Agent so long as such successor Agent is also a Lender at the time of such appointment and (ii) the Majority Lenders shall have the right to appoint a successor Agent that is not a Lender at the time of such appointment so long as the Borrower consents to such appointment (which consent shall not be unreasonably withheld). If no successor Agent shall have been so appointed by the Majority Lenders and accepted such appointment within 30 days after the retiring Agent’s giving of notice of resignation, then the retiring Agent may, on behalf of the Lenders, and with the consent of the Borrower which shall not be unreasonably withheld, appoint a

successor Agent. Any successor Agent shall be a bank which has an office in the United States and a combined capital and surplus of at least $500,000,000.00. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations as Agent thereafter arising hereunder and under any other Credit Documents, but shall not be discharged from any liabilities for its actions as Agent prior to the date of discharge. Such successor Agent shall promptly specify by notice to the Borrower its principal office referred to in Section 2.1 and Section 2.2 hereof. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 8 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Agent.

No Partnership. Neither the execution and delivery of this Agreement nor any of the other Credit Documents nor any interest the Lenders, the Agent or any of them may now or hereafter have in all or any part of the Obligations shall create or be construed as creating a partnership, joint venture or other joint enterprise between the Lenders or among the Lenders and the Agent. The relationship between the Lenders, on the one hand, and the Agent, on the other, is and shall be that of principals and agent only, and nothing in this Agreement or any of the other Credit Documents shall be construed to constitute the Agent as trustee or other fiduciary for any Lender or to impose on the Agent any duty, responsibility or obligation other than those expressly provided for herein and therein.

Miscellaneous.

No Waiver, Amendments. No waiver of any Default shall be deemed to be a waiver of any other Default. No failure to exercise or delay in exercising any right or power under any Credit Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power preclude any further or other exercise thereof or the exercise of any other right or power. Except as may be prohibited by Section 8.1 hereof, no amendment, modification or waiver of any Credit Document shall be effective unless the same is in writing and signed by the Borrower and the Majority Lenders. No notice to or demand on the Borrower or any other Person shall entitle the Borrower or any other Person to any other or further notice or demand in similar or other circumstances.

Notices. All notices under the Credit Documents shall be in writing and either (i) delivered against receipt therefor, or (ii) mailed by registered or certified mail, return receipt requested, in each case addressed as set forth herein, or to such other address as a party may designate. Notices shall be deemed to have been given (whether actually received or not) when delivered (or, if mailed, on the next Business Day). Provided, however, that as between the Agent and the Lenders and among the Lenders, notice may be given by telecopy or facsimile effective upon the earlier of actual receipt or confirmation of receipt by telephone.

Submission to Jurisdiction. THE BORROWER AND PARENT EACH HEREBY IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, TO BORROWER OR PARENT, AS THE CASE MAY BE, AT THE ADDRESS ESTABLISHED PURSUANT TO SECTION 10.2 HEREOF. THE BORROWER AND PARENT EACH HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS IN ▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇ LOCATED IN NEW YORK COUNTY, OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIMS THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. THE BORROWER AND THE PARENT EACH (A) AGREES TO DESIGNATE AND MAINTAIN AN AGENT FOR SERVICE OF PROCESS IN THE STATE OF NEW YORK IN CONNECTION WITH ANY SUCH SUIT, ACTION OR PROCEEDING AND TO DELIVER TO THE

AGENT EVIDENCE THEREOF AND (B) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH SUIT, ACTION OR PROCEEDING BY PROVIDING SUCH SERVICE OF PROCESS TO SUCH AGENT FOR SERVICE OF PROCESS. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE AGENT OR THE LENDERS TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE BORROWER OR PARENT IN ANY JURISDICTION OR TO SERVE PROCESS IN ANY MANNER PERMITTED BY APPLICABLE LAW. THE BORROWER AND THE PARENT EACH HEREBY IRREVOCABLY AGREES THAT ANY SUIT, ACTION OR PROCEEDING AGAINST THE AGENT OR ANY LENDER ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR THE OTHER CREDIT DOCUMENTS SHALL BE BROUGHT AND MAINTAINED IN THE COURTS OF THE STATE OF NEW YORK LOCATED IN NEW YORK COUNTY, OR THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK.

Choice of Law. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PERSONS EXECUTING THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED AND TO BE PERFORMED ENTIRELY WITHIN THAT STATE.

Survival; Parties Bound; Successors and Assigns.

All representations, warranties, covenants and agreements made by or on behalf of the Borrower in connection herewith shall survive the execution and delivery of the Credit Documents, shall not be affected by any investigation made by any Person, and shall bind the Borrower and its successors, trustees, receivers and assigns and inure to the benefit of the successors and assigns of the Agent and the Lenders; provided, however, that (i) the Borrower may not assign or transfer any of its rights or obligations hereunder without the prior written consent of the Agent and all of the Lenders, and any such assignment or transfer without such consent shall be null and void, and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Affiliates of each of the Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Lender Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) the Borrower, provided that no consent of the Borrower shall be required if a Default has occurred and is continuing; and

(B) the Agent.

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Lender Commitment or Loans, the amount of the Lender Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Agent) shall not be less than $10,000,000 unless each of the Borrower and the Agent otherwise consent, provided that no such consent of the Borrower shall be required if a Default has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;

(C) the parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption, together with a processing and recordation fee paid by the assigning Lender of $2,500; and

(D) the assignee, if it shall not be a Lender, shall deliver to the Agent an Administrative Questionnaire.

For the purposes of this Section 10.5, the term “Approved Fund” has the following meaning:

“Approved Fund” shall mean any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 3.5, 5.10, 5.11 and 9.7). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices, a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Lender Commitment of, and principal amount of the Loans owing to each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and Borrower, Agent, and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

A Lender may sell participating interests to an Affiliate of the Lender with written notice to the Agent and the Borrower but not any consent of the Agent, the Borrower or any other Lender, and may sell participating interests in any of its Loans to an Approved Fund so long as such participation shall (1) limit the voting rights of the participant, if any, to the ability to vote for changes in the amount of the Commitment, the interest rate on the Loans, and the Maturity Date, (2) if the participant is not an Affiliate of the participating Lender, require the written consent of the Borrower (so long as no Default is in existence) and the Agent, such consent not to be unreasonably withheld, (3) be in a minimum principal amount of at least $10,000,000.00 if participated to a Person not already a Lender, and (4) not reduce the Lender’s Lender Commitment which has not been participated to less than $10,000,000.00. In connection with any sale of a participating interest made in compliance with this Agreement, (i) the participating Lender shall continue to be liable for its Lender Commitment and its other obligations under the Credit Documents, (ii) the Agent, the Borrower and the other Lenders shall continue to deal solely and directly with the participating Lender in connection with such Lender’s rights and obligations under the Credit Documents, and (iii) the participant may not require the participating Lender to take or refrain from taking any action under the Credit Documents that is in conflict with the terms and provisions of the Credit Documents.

Notwithstanding any provision hereof to the contrary, (i) any Lender may assign and pledge all or any portion of its Lender Commitment and Loans to a Federal Reserve Bank; provided, however, that any such assignment or pledge shall not relieve such Lender from its obligations under the Credit Documents; and (ii) the Agent may not assign or participate its Lender Commitment so that its Lender Commitment after such assignment or participation is less than $15,000,000.00, to any Person other than an Affiliate of the Agent without the prior written consent of the Borrower, so long as no Default is in existence.

The term of this Agreement shall be until the final maturity of the Notes and the payment of all amounts due under the Credit Documents.

Counterparts. This Agreement may be executed in several identical counterparts, and by the parties hereto on separate counterparts, and each counterpart, when so executed and delivered, shall constitute an original instrument, and all such separate counterparts shall constitute but one and the same instrument.

Usury Not Intended. It is the intent of the parties in the execution and performance of this Agreement to contract in strict compliance with applicable usury laws from time to time in effect. In furtherance thereof, the Agent, the Lenders and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay for the use, forbearance or detention of money with interest at a rate in excess of an applicable Ceiling Rate, if any. The provisions of this paragraph shall control over all other provisions of the Credit Documents which may be in apparent conflict herewith.

Captions. The headings and captions appearing in the Credit Documents have been included solely for convenience and shall not be considered in construing the Credit Documents.

Severability. If any provision of any Credit Documents shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality and enforceability of the remaining provisions shall not be affected or impaired thereby.

Disclosures. Every reference in the Credit Documents to disclosures of the Borrower to the Agent and the Lenders in writing, to the extent that such references refer to disclosures at or prior to the execution of this Agreement, shall be deemed strictly to refer only to written disclosures delivered to the Agent and the Lenders in an orderly manner concurrently with the execution hereof.

Limitation of Liability. NO OBLIGATION OR LIABILITY WHATSOEVER OF THE BORROWER WHICH MAY ARISE AT ANY TIME UNDER THIS AGREEMENT OR ANY OBLIGATION OR LIABILITY WHICH MAY BE INCURRED BY IT PURSUANT TO ANY OTHER CREDIT DOCUMENT SHALL BE PERSONALLY BINDING UPON, NOR SHALL RESORT FOR THE ENFORCEMENT THEREOF BE HAD TO THE PRIVATE PROPERTY OF, ANY OF THE BORROWER’S TRUSTEES OR SHAREHOLDERS REGARDLESS OF WHETHER SUCH OBLIGATION OR LIABILITY IS IN THE NATURE OF CONTRACT, TORT OR OTHERWISE.

Entire Agreement. THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS TOGETHER REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

WAIVERS OF JURY TRIAL. THE BORROWER, THE PARENT, THE AGENT, THE LENDERS AND ANY OTHER PERSON EXECUTING THIS AGREEMENT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY SUIT, ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

USA Patriot Act. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies the Borrower that pursuant to the

requirements of 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 Lender to identify the Borrower in accordance with the Act.

NOTE


$[ ]		, 2007

FOR VALUE RECEIVED ARCHSTONE-▇▇▇▇▇ OPERATING TRUST, a Maryland real estate investment trust (herein called “Maker”) promises to pay to the order of [ ], a [ ] (“Payee”), at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Senior Funding, Inc., as “Agent” under the Credit Agreement, at [ ], New York, New York ___, or at such other place as the holder (the “Holder”, whether or not Payee is such holder) of this note may hereafter designate in writing, in immediately available funds and in lawful money of the United States of America, the principal sum of [ ] Dollars ($[ ]) (or the unpaid balance of all principal advanced against this note, if that amount is less), together with interest on the unpaid principal balance of this note from time to time outstanding at the Stated Rate and interest on all past due amounts, both principal and accrued interest, at the Past Due Rate; provided, that for the full term of this note the interest rate produced by the aggregate of all sums paid or agreed to be paid to the Holder of this note for the use, forbearance or detention of the debt evidenced hereby (including, but not limited to, all interest on this note at the Stated Rate) shall not exceed the Ceiling Rate.

1. Definitions. Any terms not defined herein shall have the meaning given to them in the Credit Agreement dated as of May 29, 2007 among the Maker, Archstone-▇▇▇▇▇ Trust, the Agent and certain other Lenders (as the same may be amended or modified the “Credit Agreement”).

2. Rates Change Automatically and Without Notice. Without notice to Maker or any other person or entity and to the full extent allowed by applicable law from time to time in effect, the Prime Rate and the Ceiling Rate shall each automatically fluctuate upward and downward as and in the amount by which Agent’s said prime rate, and such maximum nonusurious rate of interest permitted by applicable law, respectively, fluctuate.

3. Calculation of Interest. Interest for Eurodollar Rate Borrowings shall be computed for the actual number of days elapsed in a calendar year (up to 365, or 366 in a leap year) deemed to consist of 360 days. Interest for Base Rate Borrowings shall be computed on the basis of the actual number of days elapsed in the applicable calendar year in which it accrued.

4. Payment Schedule. The principal of this note shall be due and payable on the Maturity Date. Accrued and unpaid interest shall be due and payable on each Interest Payment Date.

5. Prepayment. Maker may prepay this note only as provided in the Credit Agreement.

6. Borrowings. Upon and subject to the terms and conditions of the Credit Agreement and the other provisions of this note, Maker may borrow against this note at any time during the Draw Period unless and until a Default has occurred which the Holder has not declared to have been fully cured or waived, and (except as the Credit Agreement or any of the other Credit Documents may otherwise provide) there is no limit on the number of advances against this note so long as the total unpaid principal of this note at any time outstanding does not exceed the Payee’s Lender Commitment. Interest on the amount of each advance against this note shall be computed on the amount of the unpaid balance of that advance from the date it is made until the date it is repaid. If Maker’s right (if any) to borrow against this note shall ever lapse because of the occurrence of any default, it shall not be reinstated (or construed from any course of conduct or otherwise to have been reinstated) unless and until the Agent shall declare in a signed writing that it has been cured or waived. The unpaid principal balance of this note at any time shall be the total of all principal lent against this note to Maker or for Maker’s account less the sum of all principal payments and permitted prepayments on this note received by the Holder. Absent manifest error, the Holder’s computer records shall on any day conclusively evidence the unpaid balance of this note and its advances and payments history posted up to that day. All loans and advances and all payments and permitted prepayments made on this note may be (but are not required to be) endorsed by the Holder on the schedule attached hereto (which is hereby made a part hereof for all purposes) or otherwise recorded in the Holder’s computer or manual records; provided, that any Holder’s failure to make notation of (a) any principal advance or accrual of interest shall not cancel, limit or otherwise affect Maker’s obligations or any Holder’s rights with respect to that advance or accrual, or (b) any payment or permitted prepayment of principal or interest shall not cancel, limit or otherwise affect Maker’s entitlement to credit for that payment as of the date of its receipt by the Holder.

7. Credit Agreement. This note has been issued pursuant to the terms of the Credit Agreement, to which reference is made for all purposes. Advances against this note by Payee or other Holder hereof shall be governed by the Credit Agreement. Payee is entitled to the benefits of the Credit Agreement. Maker hereby grants to Payee and all other present and future Holders a contractual right of setoff in and to, all property and any and all deposits (general or special, time or demand, provisional or final) at any time held by the Payee or other Holder for any Maker’s credit or account.

8. Defaults and Remedies. Upon the occurrence of any Event of Default the Holder may elect to exercise any or all rights, powers and remedies afforded (a) under the Credit Agreement and all other Credit Documents and (b) by law, including the right to accelerate the maturity of this entire note.

In addition to and cumulative of such rights, the Holder is hereby authorized at any time and from time to time after any such default, at Holder’s option, without notice to Maker or any other person or entity (all rights to any such notice being hereby waived), to set off and apply any and all of any Maker’s deposits at any time held by the Holder, and any other debt at any time owing by the Holder to or for the credit or account of any

Maker, against the outstanding balance of this note, in such order and manner as Holder may elect in its sole discretion.

9. Waivers. Except only for any notices which are specifically required by the Credit Agreement, Maker and any and all co-makers, endorsers, guarantors and sureties severally waive notice (including, but not limited to, notice of intent to accelerate and notice of acceleration, notice of protest and notice of dishonor), demand, presentment for payment, protest, diligence in collecting and the filing of suit for the purpose of fixing liability and consent that the time of payment hereof may be extended and re-extended from time to time without notice to any of them. Each such person agrees that his, her or its liability on or with respect to this note shall not be affected by any release of or change in any guaranty at any time existing or by the partial or complete unenforceability of any guaranty or other surety obligation, in each case in whole or in part, with or without notice and before or after maturity.

10. Governing Law, Jurisdiction and Venue. This note shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York.

11. Participations and Assignments. Payee and each other Holder reserves the right, exercisable in such Holder’s discretion and without notice to Maker or any other person, to sell participations, assign interests or both, in all or any part of this note or the debt evidenced by this note, in accordance with the Credit Agreement.

12. Limitation of Liability. No obligation or liability whatsoever of Maker which may arise at any time under this promissory note or any obligation or liability which may be incurred by it pursuant to any other instrument, transaction or undertaking contemplated hereby shall be personally binding upon, nor shall resort for the enforcement thereof be had to the private property of, any of Maker’s trustees or shareholders regardless of whether such obligation or liability is in the nature of contract, tort or otherwise.

13. WAIVERS OF JURY TRIAL. MAKER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY SUIT, ACTION OR PROCEEDING RELATING TO THIS NOTE AND FOR ANY COUNTERCLAIM THEREIN

WHEREAS, the Borrower and Guarantor, though separate legal entities, are mutually dependent on each other in the conduct of their respective businesses as an integrated operation and have determined it to be in their mutual best interests to obtain financing from the Agent and the Lenders through their collective efforts;

WHEREAS, Guarantor acknowledges that it will receive direct and indirect benefits from the Agent and the Lenders making such financial accommodations available to the Borrower under the Credit Agreement and, accordingly, Guarantor is willing to guarantee the Borrower’s obligations to the Agent and the Lenders on the terms and conditions contained herein; and

WHEREAS, Guarantor’s execution and delivery of this Guaranty is one of the conditions precedent to the Agent and the Lenders making, or continuing to make, such financial accommodations to the Borrower.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by Guarantor, Guarantor agrees as follows:

Section 1. Guaranty. Guarantor hereby absolutely and unconditionally guaranties the due and punctual payment and performance of all of the following (collectively referred to as the “Obligations”): (a) all indebtedness and obligations owing by the Borrower to any of the Lenders or the Agent under or in connection with the Credit Agreement and any other Credit Document, including without limitation, the repayment of all principal of the Loans made by the Lenders to the Borrower under the Credit Agreement and the payment of all interest, fees, charges, reasonable attorneys fees and other amounts payable to any Lender or the Agent thereunder or in connection therewith; (b) any and all extensions, renewals, modifications, amendments or substitutions of the foregoing; and (c) all expenses, including, without limitation, reasonable attorneys’ fees and disbursements, that are incurred by the Lenders or the Agent in the enforcement of any of the foregoing or any obligation of Guarantor hereunder.

Section 2. Guaranty of Payment and Not of Collection. This Guaranty is a guaranty of payment, and not of collection, and a debt of Guarantor for its own account. Accordingly, the Lenders and the Agent shall not be obligated or required before enforcing this Guaranty against Guarantor: (a) to pursue any right or remedy the Lenders or the Agent may have against the Borrower, any other guarantor or any other Person or commence any suit or other proceeding against the Borrower, any other guarantor or any other Person in any court or other tribunal; (b) to make any claim in a liquidation or bankruptcy of the Borrower, any other guarantor or any other Person; or (c) to make demand of the Borrower, any other guarantor or any other Person or to enforce or seek to enforce or realize upon any collateral security held by the Lenders or the Agent which may secure any of the Obligations. In this connection, Guarantor hereby waives its right to require any holder of the Obligations to take action against the Borrower as provided by any Legal Requirement.

Section 3. Guaranty Absolute. Guarantor guarantees that the Obligations will be paid strictly in accordance with the terms of the documents evidencing the same, regardless of any Legal Requirement now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Agent or the Lenders with respect thereto.

The liability of Guarantor under this Guaranty shall be absolute and unconditional in accordance with its terms and shall remain in full force and effect without regard to, and shall not be released, suspended, discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever, including without limitation, the following (whether or not Guarantor consents thereto or has notice thereof):

(a) (i) any change in the amount, interest rate or due date or other term of any of the Obligations, (ii) any change in the time, place or manner of payment of all or any portion of the Obligations, (iii) any amendment or waiver of, or consent to the departure from or other indulgence with respect to, the Credit Agreement, any other Credit Document, or any other document or instrument evidencing or relating to any Obligations, or (iv) any waiver, renewal, extension, addition, or supplement to, or deletion from, or any other action or inaction under or in respect of, the Credit Agreement, any of the other Credit Documents, or any other documents, instruments or agreements relating to the Obligations or any other instrument or agreement referred to therein or evidencing any Obligations or any assignment or transfer of any of the foregoing;

(b) any lack of validity or enforceability of the Credit Agreement, any of the other Credit Documents, or any other document, instrument or agreement referred to therein or evidencing any Obligations or any assignment or transfer of any of the foregoing;

(c) any furnishing to the Agent or the Lenders of any security for the Obligations, or any sale, exchange, release or surrender of, or realization on, any collateral security for the Obligations;

(d) any settlement or compromise of any of the Obligations, any security therefor, or any liability of any other party with respect to the Obligations, or any subordination of the payment of the Obligations to the payment of any other liability of the Borrower;

(e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or other like proceeding relating to any other guarantor, the Borrower or any other Person, or any action taken with respect to this Guaranty by any trustee or receiver, or by any court, in any such proceeding;

(f) any nonperfection of any security interest or other Lien on any of the collateral securing any of the Obligations;

(g) any act or failure to act by the Borrower or any other Person which may adversely affect Guarantor’s subrogation rights, if any, against the Borrower to recover payments made under this Guaranty;

(h) any application of sums paid by the Borrower or any other Person with respect to the liabilities of the Borrower to the Agent or the Lenders, regardless of what liabilities of the Borrower remain unpaid;

(i) any defect, limitation or insufficiency in the borrowing powers of the Borrower or in the exercise thereof; or

(j) any other circumstance which might otherwise constitute a defense available to, or a discharge of, Guarantor hereunder.

Section 4. Action with Respect to Obligations. The Lenders and the Agent may, at any time and from time to time, without the consent of, or notice to, Guarantor, and without discharging Guarantor from its obligations hereunder take any and all actions described in Section 3 and may otherwise: (a) amend, modify, alter or supplement the terms of any of the Obligations, including, but not limited to, extending or shortening the time of payment of any of the Obligations or the interest rate that may accrue on any of the Obligations; (b) amend, modify, alter or supplement the Credit Agreement or any other Credit Document; (c) sell, exchange, release or otherwise deal with all, or any part, of any collateral securing any of the Obligations; (d) release any Person liable in any manner for the payment or collection of the Obligations; (e) exercise, or refrain from exercising, any rights against the Borrower or any other Person (including, without limitation, any other guarantor); and (f) apply any sum, by whomsoever paid or however realized, to the Obligations in such order as the Lenders or the Agent shall elect.

Section 5. [Reserved]

Section 6. Covenants. Guarantor specifically agrees that to the extent Guaranty Proceeds (as defined in Section 7.3(a) of the Credit Agreement) are distributed to holders of Public Debt or their respective trustees (as defined in Section 7.3(a) of the Credit Agreement) pursuant to Section 7.3 of the Credit Agreement, the Obligations will not be deemed to be reduced by any such distributions and Guarantor shall continue to make payments under this Guaranty until such time as the Obligations have been paid in full (and the Commitment has been terminated), after taking into account any such distributions of payments hereunder in report of Indebtedness other than the Obligations.

Section 7. Waiver. Guarantor, to the fullest extent permitted by applicable law, hereby waives notice of acceptance hereof or any presentment, demand, protest or notice of any kind, and any other act or thing, or omission or delay to do any other act or thing, which in any manner or to any extent might vary the risk of Guarantor or which otherwise might operate to discharge Guarantor from its obligations hereunder.

Section 8. Inability to Accelerate Loan. If the Agent and/or the Lenders are prevented from demanding or accelerating payment thereof by reason of any automatic stay or otherwise, the Agent and/or the Lenders shall be entitled to receive from Guarantor, upon demand therefor, the sums which otherwise would have been due had such demand or acceleration occurred.

Section 9. Reinstatement of Obligations. Guarantor agrees that this Guaranty shall continue to be effective or be reinstated, as the case may be, with respect to any Obligations if at any time payment of any such Obligations is rescinded or otherwise must be restored by the Agent and/or the Lenders upon the bankruptcy or reorganization of the Borrower or Guarantor or otherwise.

Section 10. Subrogation. Until all of the Obligations shall have been indefeasibly paid in full, Guarantor shall not have any right of subrogation and Guarantor hereby waives any right to enforce any remedy which the Agent and/or the Lenders now have or may hereafter have against the Borrower, and Guarantor hereby waives any benefit of, and any right to participate in, any security or collateral given to the Agent and the Lenders to secure payment or performance of any of the Obligations.

Section 11. Payments Free and Clear. All sums payable by Guarantor hereunder, whether of principal, interest, fees, expenses, premiums or otherwise, shall be paid in full, without set-off or counterclaim or any deduction or withholding whatsoever (including any withholding tax or liability imposed by any Governmental Authority, or any Legal Requirement promulgated thereby), and if Guarantor is required by such Legal Requirement or by such Governmental Authority to make any such deduction or withholding, Guarantor shall pay to the Agent and the Lenders such additional amount as will result in the receipt by the Agent and the Lenders of the full amount payable hereunder had such deduction or withholding not occurred or been required.

Section 12. Set-off. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, each Lender is hereby authorized by Guarantor, at any time or from time to time, without notice to Guarantor or to any other Person, any such notice being hereby expressly waived, but subject to receipt of Agent’s prior written consent, to set-off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other indebtedness at any time held or owing by such Lender or any Affiliate of such Lender, to or for the credit or the account of Guarantor against and on account of any of the Obligations then due and owing after the expiration of any applicable grace periods. Guarantor 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 applicable provisions of the Credit Agreement, may exercise rights of setoff or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of Guarantor in the amount of such participation.

Section 13. Subordination. Guarantor hereby expressly covenants and agrees for the benefit of the Agent and the Lenders that all obligations and liabilities of the Borrower to Guarantor of whatever description, including without limitation, all intercompany receivables of Guarantor from the Borrower (collectively, the “Junior Claims”) shall be subordinate and junior in right of payment to all Obligations. If an Event of Default shall have occurred and be continuing, then Guarantor shall not accept any direct or indirect payment (in cash, property, securities by setoff

or otherwise) from the Borrower on account of or in any manner in respect of any Junior Claim until all of the Obligations have been indefeasibly paid in full.

Section 14. Avoidance Provisions. It is the intent of Guarantor, the Agent and the Lenders that in any Proceeding, Guarantor’s maximum obligation hereunder shall equal, but not exceed, the maximum amount which would not otherwise cause the obligations of Guarantor hereunder (or any other obligations of Guarantor to the Agent and the Lenders) to be avoidable or unenforceable against Guarantor in such Proceeding as a result of applicable law, including without limitation, (a) Section 548 of the Bankruptcy Code of 1978, as amended (the “Bankruptcy Code”) and (b) any state fraudulent transfer or fraudulent conveyance act or statute applied in such Proceeding, whether by virtue of Section 544 of the Bankruptcy Code or otherwise. The applicable laws under which the possible avoidance or unenforceability of the obligations of Guarantor hereunder (or any other obligations of Guarantor to the Agent and the Lenders) shall be determined in any such Proceeding are referred to as the “Avoidance Provisions”. Accordingly, to the extent that the obligations of Guarantor hereunder would otherwise be subject to avoidance under the Avoidance Provisions, the maximum Obligations for which Guarantor shall be liable hereunder shall be reduced to that amount which, as of the time any of the Obligations are deemed to have been incurred under the Avoidance Provisions, would not cause the obligations of Guarantor hereunder (or any other obligations of Guarantor to the Agent and the Lenders), to be subject to avoidance under the Avoidance Provisions. This Section is intended solely to preserve the rights of the Agent and the Lenders hereunder to the maximum extent that would not cause the obligations of Guarantor hereunder to be subject to avoidance under the Avoidance Provisions, and neither Guarantor nor any other Person shall have any right or claim under this Section as against the Agent and the Lenders that would not otherwise be available to such Person under the Avoidance Provisions.

Section 15. Information. Guarantor assumes all responsibility for being and keeping itself informed of the financial condition of the Borrower and of all other circumstances bearing upon the risk of nonpayment of any of the Obligations and the nature, scope and extent of the risks that Guarantor assumes and incurs hereunder, and agrees that none of the Agent or any Lender shall have any duty whatsoever to advise Guarantor of information regarding such circumstances or risks.

Section 16. Governing Law. THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED IN AND TO BE PERFORMED ENTIRELY WITHIN THAT STATE.

Section 17. JURISDICTION, VENUE. GUARANTOR HEREBY IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF THIS GUARANTY OR ANY OF THE OTHER CREDIT DOCUMENTS BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, RETURN RECEIPT REQUESTED, TO GUARANTOR AT THE ADDRESS SET FORTH AFTER ITS SIGNATURE. GUARANTOR HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY OR ANY OF THE OTHER CREDIT DOCUMENTS IN ▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇ LOCATED IN NEW YORK COUNTY, OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIMS THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. GUARANTOR (A) AGREES TO DESIGNATE AND MAINTAIN AN AGENT FOR SERVICE OF PROCESS IN THE STATE OF NEW YORK IN CONNECTION WITH ANY SUCH SUIT, ACTION OR PROCEEDING AND TO DELIVER TO THE AGENT EVIDENCE THEREOF AND (B) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH SUIT, ACTION OR PROCEEDING BY PROVIDING SUCH SERVICE OF PROCESS TO SUCH AGENT FOR SERVICE OF PROCESS. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE AGENT OR THE LENDERS TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST GUARANTOR IN ANY JURISDICTION OR TO SERVE PROCESS IN ANY MANNER PERMITTED BY APPLICABLE LAW. GUARANTOR HEREBY IRREVOCABLY AGREES THAT ANY SUIT, ACTION OR PROCEEDING AGAINST THE AGENT OR ANY LENDER ARISING

OUT OF OR IN CONNECTION WITH THIS GUARANTY OR THE OTHER CREDIT DOCUMENTS SHALL BE BROUGHT AND MAINTAINED IN THE COURTS OF THE STATE OF NEW YORK LOCATED IN NEW YORK COUNTY, OR THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK.

Section 18. Loan Accounts. The Agent may maintain books and accounts setting forth the amounts of principal, interest and other sums paid and payable with respect to the Obligations, and in the case of any dispute relating to any of the outstanding amount, payment or receipt of Obligation or otherwise, the entries in such account shall be binding upon Guarantor as to the outstanding amount of such Obligations and the amounts paid and payable with respect thereto absent manifest error. The failure of the Agent to maintain such books and accounts shall not in any way relieve or discharge Guarantor of any of its obligations hereunder.

Section 19. Waiver of Remedies. No delay or failure on the part of the Agent or the Lenders in the exercise of any right or remedy it may have against Guarantor hereunder or otherwise shall operate as a waiver thereof, and no single or partial exercise by the Agent or the Lenders of any such right or remedy shall preclude other or further exercise thereof or the exercise of any other such right or remedy.

Section 20. Successors and Assigns. Each reference herein to the Agent or the Lenders shall be deemed to include such Person’s respective successors and assigns (including, but not limited to, any holder of the Obligations) in whose favor the provisions of this Guaranty also shall inure, and each reference herein to Guarantor shall be deemed to include the Guarantor’s successors and assigns, upon whom this Guaranty also shall be binding. The Lenders and the Agent may, in accordance with the applicable provisions of the Credit Agreement, assign, transfer or sell any Obligation, or grant or sell participation in any Obligations, to any Person or entity without the consent of, or notice to, Guarantor and without releasing, discharging or modifying Guarantor’s obligations hereunder. Guarantor hereby consents to the delivery by the Agent or any Lender to any assignee, transferee or participant of any financial or other information regarding the Borrower or Guarantor. Guarantor may not assign or transfer its obligations hereunder to any Person.

Section 21. Amendments. This Guaranty may not be amended except as provided in the Credit Agreement.

GUARANTY OF COLLECTION

THIS GUARANTY (this “Guaranty”), dated as of is made by (the “Guarantor”), in favor of (a) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Senior Funding, Inc., in its capacity as Administrative Agent (the “Agent”) for the Lenders under that certain Credit Agreement dated as of May 29, 2007 by and among Archstone-▇▇▇▇▇ Operating Trust (the “Borrower”), Archstone-▇▇▇▇▇ Trust, the financial institutions party thereto and their assignees in accordance therewith (the “Lenders”), and the Agent (as the same may be amended, restated, supplemented, or otherwise modified from time to time in accordance with its terms, the “Credit Agreement”) and (b) the Lenders.

PRELIMINARY STATEMENT. Capitalized terms not otherwise defined herein shall have the respective meanings assigned thereto under the Credit Agreement. The Guarantor is a beneficial common unitholder of the Borrower and therefore the Guarantor has determined that the making of the Loan by the Lenders benefited, directly or indirectly, the Guarantor. If other beneficial common unitholders of the Borrower have entered into similar guaranty agreements (the “Other Guarantees”) with the Agent as this Guaranty, they shall be referred to in this Guaranty as the “Other Guarantors.”

NOW, THEREFORE, in consideration of the premises, the Guarantor hereby agrees as follows:

SECTION 1. Guaranty. This guaranty constitutes a limited guaranty of collection. The Guarantor hereby guarantees the punctual collection when due, on a several basis, whether at stated maturity, by demand, acceleration or otherwise, of (a) that portion of the principal and interest outstanding on the indebtedness of the Borrower under the Credit Agreement that remains outstanding equal to $ ___ [THIS NUMBER IS INTENDED TO BE THE ACTUAL AMOUNT OF GUARANTEE] less such amounts as the Agent has collected upon exercising all rights, assertion of all claims and demands and enforcement of all remedies available to it (other than this Guaranty and the Other Guarantees) under the Credit Documents, and (b) reasonable attorney’s fees and all costs and expenses incurred in enforcing any rights under this Guaranty (such obligations being the “Obligations”). An objective of this guaranty is that the Obligation shall be a “recourse liability” as defined in Treasury Regulation §1.752-1(a)(1), and the Guarantor shall bear the economic risk of loss with respect to such portion of the liabilities as is equal to the Obligations within the meaning of Treasury Regulation §1.752-2.

SECTION 2. Guaranty Absolute. The Guarantor hereby guarantees that the Obligations will be paid strictly in accordance with their terms, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Agent with respect thereto. The liability of the Guarantor under this Guaranty shall be absolute and unconditional irrespective of:

	(a)		Any lack of validity or enforceability of the Credit Agreement or any other Credit Documents or agreement relating thereto or executed in connection therewith;

	(b)		Any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations or any other amendment or waiver of or any consent to any departure from the Credit Agreement, any other Credit Documents or any other documents or agreement relating thereto or executed in connection therewith;

	(c)		Any exchange, release or non-perfection of collateral, if any, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Obligations; or

	(d)		Any other circumstance which might otherwise constitute a defense available to, or a discharge of, the Borrower, any subsidiary of the Borrower or any other person that is a party to the Credit Agreement, any other Credit Documents or any other document or agreement related thereto or executed in connection therewith (including any guarantor) in respect to the Obligations.

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Obligations is rescinded or must otherwise be returned by the Agent or any Lender upon the insolvency, bankruptcy or reorganization of the Borrower or Guarantor or otherwise, all as though such payment had not been made. The obligations of the Guarantor under this Guaranty shall not be subject to reduction, termination or other impairment by reason of any setoff, recoupment, counterclaim or defense or for any other reason. This Guaranty is to be in addition to and is not to prejudice or be prejudiced by any other securities or guaranties (including any guaranty signed by the Guarantor) which the Agent may now or hereafter hold from or on account of the Borrower and is to be binding on the Guarantor as a continuing guaranty notwithstanding any payments from time to time made to the Agent or any settlement of account or disability or incapacity affecting the Guarantor or any other thing whatsoever.

SECTION 3. Representations and Warranties. Guarantor hereby represents and warrants that it has the requisite power and authority to execute and deliver and to carry out this Guaranty and the transactions contemplated herein; and to perform its obligations hereunder. This Guaranty has been duly and validly executed and delivered by the Guarantor and constitutes a valid and legally binding agreement of the Guarantor, enforceable in accordance with its terms.

SECTION 4. Waiver. The Guarantor waives any notice with respect to any of the Obligations and this Guaranty (it being the understanding of the Agent and the Guarantor that this Guaranty is a guaranty of collection and not of payment).

SECTION 5. No Subrogation. The Guarantor will not exercise any rights which it may acquire by way of subrogation under this Guaranty or in respect of any security for the Obligations, by any payment made hereunder or otherwise.

SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guaranty nor consent to any departure by the Guarantor herefrom, shall be effective unless the same is in writing and signed by the Agent and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 7. Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing or by facsimile, telegraph or cable and mailed or sent or delivered as to each party hereto at the address for notices set forth under its name on the signature page hereof or, in the case of each party, at such other address as shall be designated by such party in a written notice to all other parties. All such notices and other communications shall be effective when received, and in the case of notice by facsimile, telegraph or cable, when sent, and upon receipt of an answer back, in each case addressed as set forth above.

SECTION 8. No Waiver; Cumulative Remedies. No failure on the part of the Agent or any Lender to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 9. Absolute and Continuing Guaranty. This Guaranty is an absolute and continuing guaranty and shall (a) remain in full force and effect until full payment of the Obligations or all amounts payable under this Guaranty, (b) be binding upon the Guarantor and its successors and assigns, and (c) inure to the benefit of the Agent and its successors and assigns.

SECTION 10. Savings Clause. Nothing herein is intended to contract for, take, reserve, charge or receive interest or other consideration for the use, forbearance or detention of money at a rate in excess of the highest rate permitted by applicable laws (“Highest Lawful Rate”) nor shall the Guarantor be required to pay unearned interest.

SECTION 11. Governing Law. This Guaranty shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York.

SECTION 12. Release of Claims. Guarantor hereby releases, discharges and acquits forever the Agent, the Lenders and their respective officers, directors, trustees, agents, employees and counsel (in each case, past, present or future) from any and all Claims existing as of the date hereof (or the date of actual execution hereof by Guarantor, if later). As used herein, the term “Claim” shall mean any and all liabilities, claims, defenses, demands, actions, causes of action, judgments, deficiencies, interest, liens, costs or expenses (including court costs, penalties, attorneys’ fees and disbursements, and amounts paid in settlement) of any kind and character whatsoever, including claims for usury, breach of contract, breach of commitment, negligent misrepresentation or failure to act in good faith, in each case whether now known or unknown, suspected or unsuspected, asserted or unasserted or primary or contingent, and whether arising out of written documents, unwritten undertakings, course of conduct, tort, violations of laws or regulations or otherwise.

IN WITNESS WHEREOF, the Guarantor has caused this Guaranty to be duly executed and delivered as of the date first above written.
