For purposes hereof: “Prime Rate” shall mean, at any time, the rate of interest per annum publicly announced or otherwise identified from time to time by Wells Fargo at its principal office in San Francisco, California as its prime rate.

Any change in the Alternate Base Rate due to a change in any of the foregoing will become effective on the effective date of such change in the Federal Funds Rate, the Prime Rate or LIBOR for an Interest Period of one (1) month. Notwithstanding anything contained herein to the contrary, to the extent that any of the determinations described in Section 2.9 are made by the applicable parties, clause (c) hereof shall not be in effect and the Alternate Base Rate shall be the greater of (i) the Prime Rate in effect on such day and (ii) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%.

ARTICLE II

THE LOAN; AMOUNT AND TERMS

Section 2.1 Loan.

(a) Amount of Loan. Subject to the terms and conditions hereof and in reliance upon the representations and warranties set forth herein, each Lender severally, but not jointly, agrees to make available to the Borrower (through the Administrative Agent) on the Closing Date such Lender’s Loan Commitment Percentage of a Loan in Dollars (the “Loan”) in the aggregate principal amount of SEVENTY MILLION DOLLARS ($70,000,000) (the “Loan Committed Amount”) for the purposes hereinafter set forth (such facility, the “Loan Facility”). The Borrower shall request the Loan by submitting a Notice of Borrowing, in substantially the form of Exhibit 1.1(e), to the Administrative Agent no less than three (3)& nbsp;Business Days prior to the date requested for borrowing of the Loan, which borrowing date shall be a Business Day. Upon receipt by the Administrative Agent of the proceeds of the Loan, such proceeds will then be made available to the Borrower by the Administrative Agent by crediting the account of the Borrower on the books of the Administrative Agent with the aggregate of such proceeds made available to the Administrative Agent by the Lenders and in like funds as received by the Administrative Agent (or by crediting such other account(s) as directed by the Borrower). The Loan may consist of Alternate Base Rate Loans or LIBOR Rate Loans, as the Borrower may request in a writing delivered to the Administrative Agent; provided, however, that the Loan made on the Closing Date or any of the three (3) Business Days following the Closing Date may only consist of Alternate Base Rate Loans, unless otherwise agreed by the Administrative Agent and the Lenders, as such agreement shall be evidenced by the Administrative Agent’s acceptance of a funding indemnity letter in connection therewith. LIBOR Rate Loans shall be made by each Lender at its LIBOR Lending Office and Alternate Base Rate Loans at its Domestic Lending Office. Amounts repaid or prepaid on the Loan may not be reborrowed.

(b) Repayment of Loan. The principal amount of the Loan shall be repaid in accordance with Schedule 2.1. On the Maturity Date, the remaining principal balance of the Loan and all accrued but unpaid interest and all other amounts payable with respect to the Loan shall be repaid in full.

(i) Alternate Base Rate Loans. During such periods as the Loan shall be comprised of Alternate Base Rate Loans, each such Alternate Base Rate Loan shall bear interest at a per annum rate equal to the sum of the Alternate Base Rate plus the Applicable Percentage; and

(ii) LIBOR Rate Loans. During such periods as the Loan shall be comprised of LIBOR Rate Loans, each such LIBOR Rate Loan shall bear interest at a per annum rate equal to the sum of the LIBOR Rate plus the Applicable Percentage.

Interest on the Loan shall be payable in arrears on each Interest Payment Date.

(d) Notes; Covenant to Pay. The Borrower’s obligation to pay each Lender shall be evidenced by this Agreement and, upon such Lender’s request, by a duly executed promissory note of the Borrower to such Lender in substantially the form of Exhibit 2.1(d). The Borrower covenants and agrees to pay the Loan in accordance with the terms of this Agreement.

Section 2.2 Fees.

The Borrower agrees to pay to (i) the Administrative Agent (for its own account) the annual Administrative Fee (as such term is defined in the Engagement Letter) and (ii) the Administrative Agent (for the account of WFS) the Structuring Fee (as such term is defined in the Engagement Letter).

Section 2.3 Prepayments.

(a) Optional Prepayments. The Borrower shall have the right to prepay the Loan in whole but not in part at any time after the Closing Date, in each case on an Interest Payment Date; provided, prepayment shall also require payment of (i) all accrued, but unpaid, interest on the Loan, (ii) the applicable Prepayment Fee and (iii) all other fees, costs, expenses or other amounts then due and owing or accrued, but unpaid, pursuant to the Credit Documents. The Borrower shall give irrevocable notice of prepayment of the Loan to the Administrative Agent not later than 11:00 a.m. (New York, New York time) three (3) Business Days prior to the date of such prepayment (and the Administrative Agent shall notify the Lenders thereof as soon as practicable). To the extent that the Borrower elects to prepay the Loan, amounts prepaid under this Section shall be (i) applied in accordance with Section 2.7(a) (if no Event of Default has occurred and is continuing) or in accordance with Section 2.7(b) (if an Event of Default has occurred and is continuing) and (ii) applied to the Loan of the Lenders in accordance with their respective Loan Commitment Percentages. All prepayments under this Section shall be subject to Section 2.11 and shall otherwise require the payment of all amounts referenced in the first sentence of this Section 2.3(a).

(b) Mandatory Prepayments.

(i)�� Mortgaged Property Disposition. Promptly following any Mortgaged Property Disposition, the Borrower shall prepay the Loan in an aggregate amount equal to one hundred percent (100%) of (A) the outstanding principal balance of the Allocated Loan Amount applicable to the Mortgaged Property being disposed of, (B) the accrued, unpaid interest on that portion of the Loan applicable to the Mortgaged Property being disposed of, (C) the applicable Prepayment Fee pro rated with respect to the Mortgage

Property being disposed of, and (D) any and all other accrued, unpaid amounts under any of the Credit Documents with respect to the Loan applicable to the Mortgaged Property being disposed of. After such Mortgaged Property Disposition, the Loan shall continue as to the other Mortgaged Property and the balance of the Loan. Such prepayment shall be made on the Interest Payment Date next following the Mortgaged Property Disposition. The Borrower shall give irrevocable notice of prepayment of the Loan to the Administrative Agent not later than 11:00 a.m. (New York, New York time) three (3) Business Days prior to the date of such prepayment (and the Administrative Agent shall notify the Lenders thereof as soon as practicable).

(ii) Application of Mandatory Prepayments. All amounts required to be paid pursuant to this Section 2.3(b) shall be applied in accordance with Section 2.7(b). All prepayments under this Section shall be subject to Section 2.11 and be accompanied by interest on the principal amount prepaid through the date of prepayment.

(c) Hedging Obligations Unaffected. Any repayment or prepayment made pursuant to this Section shall not affect the Borrower’s obligation to continue to make payments under any Secured Hedging Agreement, which shall remain in full force and effect notwithstanding such repayment or prepayment, subject to the terms of such Secured Hedging Agreement.

Section 2.4 Default Rate and Payment Dates.

(a) If all or a portion of the principal amount of the Loan which is a LIBOR Rate Loan shall not be paid when due or continued as a LIBOR Rate Loan in accordance with the provisions of Section 2.5 (whether at the stated maturity, by acceleration or otherwise), such overdue principal amount of the Loan shall be converted to an Alternate Base Rate Loan at the end of the Interest Period applicable thereto.

(b) Upon the occurrence of an Event of Default, the principal of and, to the extent permitted by law, interest on the Loan and any other amounts owing hereunder or under the other Credit Documents shall automatically bear interest, payable on demand, at a per annum rate which is equal to the Default Rate. Regarding any LIBOR Rate Loan in effect upon the occurrence of an Event of Default, such LIBOR Rate Loan shall automatically (without the need for further action) be converted to an Alternate Base Rate Loan at the end of the Interest Period for such LIBOR Rate Loan.

(c) Interest on the Loan shall be payable in arrears on each Interest Payment Date; provided that interest accruing pursuant to paragraph (b) of this Section shall be payable from time to time on demand.

Section 2.5 Conversion/Continuation Options.

(a) The Borrower may elect from time to time for the Loan to be either an Alternate Base Rate Loan in its entirety or a LIBOR Rate Loan in its entirety; provided, the Loan shall not at any time be apportioned as part Alternate Base Rate Loan and part LIBOR Rate Loan. The Borrower may elect from time to time to convert the entire Loan from an Alternate Base Rate Loan to a LIBOR Rate Loan by delivering a Notice of Conversion/Extension to the Administrative Agent at least three (3) Business Days prior to the proposed date of conversion. In addition, the Borrower may elect from time to time to convert the entire Loan from a LIBOR Rate Loan to an Alternate Base Rate Loan by giving the Administrative Agent irrevocable written notice thereof by 11:00 a.m. ( New York, New York time) one (1) Business Day prior to the

proposed date of conversion. If the date upon which an Alternate Base Rate Loan is to be converted to a LIBOR Rate Loan is not a Business Day, then such conversion shall be made on the next succeeding Business Day and during the period from such initially intended conversion date to such succeeding Business Day the Loan shall bear interest as if it were an Alternate Base Rate Loan. LIBOR Rate Loans may only be converted to Alternate Base Rate Loans on the last day of the applicable Interest Period. If the date upon which a LIBOR Rate Loan is to be converted to an Alternate Base Rate Loan is not a Business Day, then such conversion shall be made on the next succeeding Business Day and during the period from such last day of an Interest Period to such succeeding Business Day the Loan shall bear interest as if it were an Alternate Base Rate Loan. The entire Loan when such is in the for m of an Alternate Base Rate Loan may be converted as provided herein; provided that the Loan may not be converted into a LIBOR Rate Loan when any Default or Event of Default has occurred and is continuing. The entire Loan when such is in the form of a LIBOR Rate Loan may be converted as provided herein.

(b) Any LIBOR Rate Loan may be continued as such upon the expiration of an Interest Period with respect thereto by compliance by the Borrower with the notice provisions (regarding conversions of Alternate Base Rate Loans to LIBOR Rate Loans) contained in Section 2.5(a); provided, that no LIBOR Rate Loan may be continued as such when any Default or Event of Default has occurred and is continuing, in which case such LIBOR Rate Loan shall be automatically converted to an Alternate Base Rate Loan at the end of the applicable Interest Period with respect thereto. If the Borrower shall fail to give timely notice of an election to continue a LIBOR Rate Loan, or the continuation of LIBOR Rate Loans is not permitted hereunder, such LIBOR Rate Loan shall be automatically conv erted to an Alternate Base Rate Loan at the end of the applicable Interest Period with respect thereto.

Section 2.6 Computation of Interest and Fees; Usury.

(a) Interest payable hereunder with respect to any Alternate Base Rate Loan based on the Prime Rate shall be calculated on the basis of a year of 365 days (or 366 days, as applicable) for the actual days elapsed. All other fees, interest and all other amounts payable hereunder shall be calculated on the basis of a 360-day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of each determination of a LIBOR Rate on the Business Day of the determination thereof. Any change in the interest rate on a Loan resulting from a change in the Alternate Base Rate shall become effective as of the opening of business on the day on which such change in the Alternate Base Rate shall become effective. The A dministrative Agent shall as soon as practicable notify the Borrower and the Lenders of the effective date and the amount of each such change.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the computations used by the Administrative Agent in determining any interest rate.

(c) It is the intent of the Lenders and the Credit Parties to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between the Lenders and the Credit Parties are hereby limited by the provisions of this subsection which shall override and control all such agreements, whether now existing or hereafter arising and whether written or oral. In no way, nor in any event or contingency (including, without limitation, but not limited to, prepayment or acceleration of the maturity of any Credit Party Obligation), shall the interest taken, reserved, contracted for, charged, or received under this

Agreement, under the Notes or otherwise, exceed the maximum nonusurious amount permissible under applicable law. If, from any possible construction of any of the Credit Documents or any other document, interest would otherwise be payable in excess of the maximum nonusurious amount, any such construction shall be subject to the provisions of this paragraph and such interest shall be automatically reduced to the maximum nonusurious amount permitted under applicable law, without the necessity of execution of any amendment or new document. If any Lender shall ever receive anything of value which is characterized as interest on the Loan under applicable law and which would, apart from this provision, be in excess of the maximum nonusurious amount, an amount equal to the amount which would have been excessive interest shall, without penalty, be applied to the reduction of the principal amount owing o n the Loan and not to the payment of interest, or refunded to the Borrower or the other payor thereof if and to the extent such amount which would have been excessive exceeds such unpaid principal amount of the Loan. The right to demand payment of the Loan or any other Indebtedness evidenced by any of the Credit Documents does not include the right to receive any interest which has not otherwise accrued on the date of such demand, and the Lenders do not intend to charge or receive any unearned interest in the event of such demand. All interest paid or agreed to be paid to the Lenders with respect to the Loan shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full stated term (including, without limitation, any renewal or extension) of the Loan so that the amount of interest on account of such Indebtedness does not exceed the maximum nonusurious amount permitted by applicable law.

Section 2.7 Pro Rata Treatment and Payments.

(a) Allocation of Payments Prior to Occurrence of Event of Default. If no Event of Default has occurred and is continuing, each payment under any of the Credit Documents or in respect of the Collateral, including, without limitation, any optional prepayment of the Loan pursuant to Section 2.3(a) but excluding any mandatory prepayment of the Loan pursuant to Section 2.3(b), shall be applied as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including, without limitation, reasonable attorneys’ fees) of the Administrative Agent under the Credit Documents and any protective advances made by the Administrative Agent with respect to the Collateral under or pursuant to the terms of the Security Documents;

SECOND, to the payment of any fees owed to the Administrative Agent pursuant to the Credit Documents;

THIRD, to the payment of all of the Credit Party Obligations consisting of accrued fees and interest, and including, without limitation, with respect to any Secured Hedging Agreement, any fees, premiums and scheduled periodic payments due under such Secured Hedging Agreement and any interest accrued thereon;

FOURTH, to the payment of the outstanding principal amount of the Credit Party Obligations, and including, without limitation, with respect to any Secured Hedging Agreement, any breakage, termination or other payments due under such Secured Hedging Agreement and any interest accrued thereon;

FIFTH, to all other Credit Party Obligations and other obligations which shall have become due and payable under the Credit Documents or otherwise and not repaid pursuant to clauses “FIRST” through “FOURTH” above; and

SIXTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category and (b) each of the Lenders and any Hedging Agreement Provider shall receive an amount equal to its pro rata share (based on the proportion that the then outstanding portion of the Loan held by such Lender or the outstanding obligations payable to such Hedging Agreement Provider bears to the aggregate then outstanding Loan and obligations payable under all Secured Hedging Agreements) of amounts available to be applied pursuant to clauses “THIRD”, “FOURTH” and “FIFTH” above. Prepayment under Section 2.3(a) shall be applied first to Alternate Base Rate Loans on a ratable basis and then to LIBOR Rate Loans (if any) in inverse order of Interest Period maturities.

Each mandatory prepayment of the Loan shall be applied to the Loan on a pro rata basis in accordance with Section 2.7(b).

(b) Allocation of Proceeds from Mandatory Prepayments or Payments After Occurrence of Event of Default. Proceeds from any mandatory prepayment of the Loan under Section 2.3(b) and proceeds arising after the occurrence and during the continuation of any Event of Default, all amounts collected or received by the Administrative Agent or any Lender on account of the Credit Party Obligations or any other amounts outstanding under any of the Credit Documents or in respect of the Collateral shall be paid over or delivered as follows (irrespective of whether the following costs, expenses, fees, interest, premiums, scheduled periodic payments or Credit Party Obligations are allowed, permitted or recognized as a claim in any proceeding resulting from the occurrence of a Bankruptcy Event):

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including, without limitation, reasonable attorneys’ fees) of the Administrative Agent in connection with enforcing the rights of the Lenders under the Credit Documents and any protective advances made by the Administrative Agent with respect to the Collateral under or pursuant to the terms of the Security Documents;

SECOND, to the payment of any fees owed to the Administrative Agent pursuant to the Credit Documents;

THIRD, to the payment of all reasonable out-of-pocket costs and expenses (including, without limitation, reasonable attorneys’ fees) of each of the Lenders in connection with enforcing its rights under the Credit Documents or otherwise with respect to the Credit Party Obligations owing to such Lender;

FOURTH, to the payment of all of the Credit Party Obligations consisting of accrued fees and interest, and including, without limitation, with respect to any Secured Hedging Agreement, any fees, premiums and scheduled periodic payments due under such Secured Hedging Agreement and any interest accrued thereon;

FIFTH, to the payment of the outstanding principal amount of the Credit Party Obligations, and including, without limitation, with respect to any Secured Hedging Agreement, any breakage, termination or other payments due under such Secured Hedging Agreement and any interest accrued thereon;

SIXTH, to all other Credit Party Obligations and other obligations which shall have become due and payable under the Credit Documents or otherwise and not repaid pursuant to clauses “FIRST” through “FIFTH” above; and

SEVENTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category and (b) each of the Lenders and any Hedging Agreement Provider shall receive an amount equal to its pro rata share (based on the proportion that the then outstanding portion of the Loan held by such Lender or the outstanding obligations payable to such Hedging Agreement Provider bears to the aggregate then outstanding Loan and obligations payable under all Secured Hedging Agreements) of amounts available to be applied pursuant to clauses “THIRD”, “FOURTH”, “FIFTH” and “SIXTH” above. Prepayment under Section 2.3(b) shall be applied first to Alternate Base Rate Loans on a ratable basis and then to LIBOR Rate Loans (if any) in inverse order of Interest Period m aturities.

(c) Payments - General Terms. All payments (including, without limitation, prepayments) to be made by the Borrower on account of principal, interest and fees shall be made without defense, set-off or counterclaim and shall be made to the Administrative Agent for the account of the Lenders at the Administrative Agent’s office specified in Section 9.2 in Dollars and in immediately available funds not later than 1:00 p.m. (New York, New York time) on the date when due. The Administrative Agent shall distribute such payments to the Lenders entitled thereto promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the LIBOR Rate Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day, and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension. If any payment on a LIBOR Rate Loan becomes due and payable on a day other than a Business Day, such payment date shall be extended to the next succeeding Business Day (and with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension) unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day.

Section 2.8 Non-Receipt of Funds by the Administrative Agent.

(a) Funding by Lenders; Presumption by the Administrative Agent. Unless the Administrative Agent shall have received written notice from a Lender prior to the proposed date of any Extension of Credit that such Lender will not make available to the Administrative Agent such Lender’s share of such Extension of Credit, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with this Agreement and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Extension of Credit available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including, without limitation, the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by the

Borrower, the interest rate applicable to Alternate Base Rate Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Extension of Credit to the Administrative Agent, then the amount so paid shall constitute such Lender’s portion of the Loan included in such Extension of Credit. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(b) Payments by Borrower; Presumptions by the Administrative Agent. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender, with interest thereon, for each day from and including, without limitation, the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

A notice of the Administrative Agent to any Lender or the Borrower with respect to any amount owing under subsections (a) and (b) of this Section shall be conclusive, absent manifest error.

(c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the Administrative Agent funds for any portion of the Loan to be made by such Lender as provided in this Article II, and such funds are not made available to the Borrower by the Administrative Agent because the conditions to the applicable Extension of Credit set forth in Article IV are not satisfied or waived in accordance with the terms thereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make the Loan and to make payments pursuant to Section 9.5(c) are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any such payment under Section 9.5(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 9.5(c).

(e) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any portion of the Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any portion of the Loan in any particular place or manner.

Section 2.9 Inability to Determine Interest Rate.

Notwithstanding any other provision of this Agreement, if (a) the Administrative Agent shall reasonably determine (which determination shall be conclusive and binding absent manifest error) that, by reason of circumstances affecting the relevant market, reasonable and adequate means do not exist for

ascertaining the LIBOR Rate for such Interest Period, or (b) the Required Lenders shall reasonably determine (which determination shall be conclusive and binding absent manifest error) that the LIBOR Rate does not adequately and fairly reflect the cost to such Lenders of funding LIBOR Rate Loans that the Borrower has requested be outstanding as a LIBOR Tranche during such Interest Period, the Administrative Agent shall forthwith give telephone notice of such determination, confirmed in writing, to the Borrower, and the Lenders at least two (2) Business Days prior to the first day of such Interest Period. Unless the Borrower shall have notified the Administrative Agent upon receipt of such telephone notice that it wishes to rescind or modify its request regarding such LIBOR Rate Loan, any portion of the Loan that was requested to be made as a LIBOR Rate Loan shall be made as an Alternate Base Rat e Loan and any portion of the Loan that was requested to be converted into or continued as a LIBOR Rate Loan shall remain as or be converted into an Alternate Base Rate Loan. Until any such notice has been withdrawn by the Administrative Agent, no further portion of the Loan shall be made as, continued as, or converted into, a LIBOR Rate Loan for the Interest Periods so affected.

Section 2.10 Yield Protection.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the LIBOR Rate);

(ii) subject any Lender to any tax of any kind whatsoever with respect to this Agreement or any LIBOR Rate Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 2.12 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender); or

(iii) impose on any Lender or the London interbank market any other condition, cost or expense affecting this Agreement or LIBOR Rate Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any LIBOR Rate Loan (or of maintaining its obligation to make any such LIBOR Rate Loan), or to increase the cost to such Lender or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or any other amount) then, upon request of such Lender, the Borrower will pay to such Lender, as the case may be, such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered, as a consequence of any of the Credit Documents or any Loan made by such Lender.

(b) Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any lending office of such Lender or such Lender’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, or the Loan made by such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation.

Section 2.11 Indemnity; Eurocurrency Liabilities.

(a) The Borrower hereby agrees to indemnify each Lender and to hold such Lender harmless from any funding loss or expense which such Lender may sustain or incur as a consequence of (i) the failure by the Borrower to pay the principal amount of or interest on any Loan by such Lender in accordance with the terms hereof, (ii) the failure by the Borrower to accept a borrowing after the Borrower has given a notice in accordance with the terms hereof, (iii) default by the Borrower in making any prepayment after the Borrower has given a notice in accordance with the terms hereof, and/or (iv) the making by the Borrower of a prepayment of the Loan or any portion thereof, or the conversion thereof, on a day which is not the last day of the Interest Period with respect there to, in each case including, without limitation, any such loss or expense arising from interest or fees payable by such Lender to lenders of funds obtained by it in order to maintain its portion of the Loan hereunder. A certificate setting forth in reasonable detail as to any additional amounts payable pursuant to this Section submitted by any Lender, through the Administrative Agent, to the Borrower shall be conclusive in the absence of manifest error. The agreements in this Section shall survive termination of this Agreement and payment of the Credit Party Obligations.

(b) The Borrower shall pay to each Lender, as long as such Lender shall be required to maintain reserves under Regulation D with respect to “Eurocurrency liabilities” within the meaning of Regulation D, or under any similar or successor regulation with respect to Eurocurrency liabilities or Eurocurrency funding, additional interest on the unpaid principal amount of each LIBOR Loan equal to the actual costs of such reserves allocated to such LIBOR Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive), which shall be due and payable on each date on which interest is payable on such LIBOR Loan, provided the Borrower shall have received at least fifteen (15) days prior notice (with a copy to the Administrative Agent) of such additional interest from such Lender. If a Lender fails to give notice fifteen (15) days prior to the relevant interest payment date, such additional interest shall be due and payable fifteen (15) days from receipt of such notice.

Section 2.12 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Credit Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if the Borrower shall be required by applicable law to deduct any Indemnified Taxes (including, without limitation, any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including, without limitation, deductions applicable to additional sums payable under this Section) the Administrative Agent or any Lender, as the case may be, receives an amount equal to the sum it

would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) Payment of Other Taxes by the Borrower. Without limiting the provisions of paragraph (a) above, the Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent and each Lender, within fifteen (15) days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including, without limitation, Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent or such Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

In addition, any Lender, if requested by the Borrower or the Administrative Agent, sh all deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

(f) Foreign Lenders. Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States, any Foreign Lender shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

(i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party,

(ii) duly completed copies of Internal Revenue Service Form W-8ECI,

(iv) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower to determine the withholding or deduction required to be made.

(g) Treatment of Certain Refunds. If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

Section 2.13 Illegality.

Notwithstanding any other provision of this Agreement, if any Change in Law shall make it unlawful for such Lender or its LIBOR Lending Office to make or maintain LIBOR Rate Loans as contemplated by this Agreement or to obtain in the interbank eurodollar market through its LIBOR Lending Office the funds with which to make such LIBOR Rate Loans, (a) such Lender shall promptly notify the Administrative Agent and the Borrower thereof, (b) the commitment of such Lender hereunder to make LIBOR Rate Loans or continue LIBOR Rate Loans as such shall forthwith be suspended until the Administrative Agent shall give notice that the condition or situation which gave rise to the suspension shall no longer exist, and (c) such Lender’s portion of the Loan then outstanding as LIBOR Rate Loans, if any, shall be converted on the last day of the Interest Period for such LIBOR Rate Loans or wit hin such earlier period as required by law into Alternate Base Rate Loans. The Borrower hereby agrees to promptly pay any Lender, upon its demand, any additional amounts necessary to compensate such Lender for actual and direct costs (but not including, without limitation, anticipated profits) reasonably incurred by such Lender in making any repayment in accordance with this Section including, without limitation, any interest or fees payable by such Lender to lenders of funds obtained by it in order to make or maintain its LIBOR Rate Loans hereunder. A certificate (which certificate shall include a description of the basis for the computation) as to any additional amounts payable pursuant to this Section submitted by such Lender, through the Administrative Agent, to the Borrower shall be conclusive in the absence of manifest error. Each Lender agrees to use reasonable efforts (including, without limitation, reasonable efforts to change its LIBOR Lending Office) to avoid or to mini mize any amounts which may otherwise be payable

pursuant to this Section; provided, however, that such efforts shall not cause the imposition on such Lender of any additional costs or legal or regulatory burdens deemed by such Lender in its sole discretion to be material.

Section 2.14 No New Extension of Credit After Closing Date.

After the initial Extension of Credit on the Closing Date, the Lenders shall have no obligation to provide any additional advance pursuant to this Agreement; provided, notwithstanding the foregoing, there shall be additional Extensions of Credit after the Closing Date in the form of conversions and continuations of the Loan pursuant to Section 2.5.

If all or any part of the Improvements at any Mortgaged Property is destroyed or damaged, said Improvements can be legally reconstructed (whether as a legal non-conforming use or otherwise) to substantially the same condition prior to such damage or destruction (except in the case of an approved legal non-conforming Mortgaged Property), and thereafter exist for the same use without violating any zoning or other ordinances applicable thereto and without the necessity of obtaining any variances or special permits, unless a change in any applicable Requirement of Law provides otherwise.

Neither the zoning nor any other right to construct, use or operate any Mortgaged Property is in any way dependent upon or related to any property other than any Mortgaged Property, except that the Maryland Mortgaged Property is located in a parking lot district and therefore no parking for the Maryland Mortgaged Property is required to be on-site but is instead supported by public garages and public transportation, and the land use and zoning approvals associated with the Maryland Mortgaged Property have been issued with respect to the Maryland Mortgaged Property and the property located at 1110 S pring Street, Silver Spring, Maryland 20910, owned in fee simple by the Borrower and generally referred to by the Borrower as the “Phase IIB property”.

To the knowledge of the Credit Parties and their Subsidiaries, there exists no material structural, mold or other material defects or damages in any Mortgaged Property, as a result of a casualty or otherwise, and whether latent or otherwise. No Credit Party has received written notice from any insurance company or bonding company of any defects or inadequacies in any Mortgaged Property, or any part thereof, which would adversely affect the insurability of the same or cause the imposition of extraordinary premiums or charges thereon or of any termination or threatened termination of any policy of insurance or bond.

(g) Boundaries. Except to the extent affirmatively insured over under the title policies, (i) none of the Improvements which were included in determining the appraised value of any Mortgaged Property lie outside the boundaries and building restriction lines of any Mortgaged Property to any material extent, and (ii) no improvements on adjoining properties encroach upon any Mortgaged Property and no easements or other encumbrances upon any Mortgaged Property encroach upon any of the Improvements so as to materially affect the value or marketability of any Mortgaged Property.

(h) Reciprocal Easement Agreements. Neither a Credit Party nor a Subsidiary thereof has given or received any written notice with respect to any alleged or current default under any of the terms and conditions of a REA as described in any title commitment for a Mortgage Policy.

same has been completed), remain in full force and effect and have not been released, terminated, extinguished or discharged by agreement or otherwise. All material sums due and owing by a Credit Party or any of its Subsidiaries to other parties to any REA (or, to the Credit Parties’ knowledge, by the other parties to each REA to a Credit Party) pursuant to the terms of such REA (including, without limitation, all sums, charges, fees, assessments, costs and expenses in connection with any taxes, site preparation and construction, non-shareholder contributions, and common area and other property management activities) have been paid, and no Lien has attached on any Mortgaged Property (or to the knowledge of the Credit Parties or their Subsidiaries, threat thereof has been made) for failure to pay any of the foregoing.

(l) Notices Related to Mortgaged Properties. No Credit Party has, on or after the date hereof, been notified in writing by any Governmental Authority or any other Person that such party has rescinded or not renewed, or is reasonably likely to rescind or not renew, any material permit, license, certification, authorization, approval, consent or agreement granted to it or to which it is a party. No Credit Party has received written notice from any insurance company or bonding company of any defects or inadequacies in any Mortgaged Property, or any part thereof, which would materially and adversely affect the insurability of the same or cause the imposition of extraord inary premiums or charges thereon or of any termination or threatened termination of any policy of insurance or bond.

(m) Modifications/Alterations to Mortgaged Properties subject to Lien of Credit Documents. Each Credit Party affirms that (i) title with respect to any and all modifications and alterations to any Mortgaged Property shall automatically (and without the need for further action) vest with the Borrower and (ii) any and all such modifications and alterations to any Mortgaged Property shall automatically (and without the need for further action) be subject to the Lien of the Credit Documents in favor of the Administrative Agent.

Each Subsidiary, designated as a Material Subsidiary by the Borrower (as described in the definition of “Material Subsidiary”), shall for all purposes of this Agreement and the other Credit Documents immediately be a Material Subsidiary and a Guarantor from the time of such designation.

Concurrent with its delivery of the Guaranty Agreement, the initial Guarantor shall: (a) execute and deliver (i) the Initial Guarantor Joinder Agreement, in form and substance reasonably satisfactory to the Administrative Agent, pursuant to which the initial Guarantor shall become a Guarantor and shall join as a party to this Agreement and the Environmental Indemnity and (ii) an officer’s certificate in the form attached hereto as Exhibit 4.1(b), with the appropriate exhibits thereto, in form and substance reasonably satisfactory to the Administrative Agent, and (b) cause to be delivered to the Administrative Agent a legal opinion regarding the initial Guarantor, the Guaranty Agreement, the Initial Guarantor Joinder Agreement and the Environmental Indemnity, substantially in the form of the legal opinions delivered on behalf of the Borrower on the Closing Da te, addressed to the Administrative Agent and the Lenders. The Guaranty Agreement, the Initial Guarantor Joinder Agreement, the officer’s certificate and the legal opinion shall all be delivered on or prior to the date sixty (60) days after the Closing Date to the Administrative Agent.

Each Subsidiary (other than such which is already a party to the Guaranty Agreement as a direct party thereto or pursuant to a prior Joinder Agreement) designated as a Material Subsidiary shall execute a Joinder Agreement, in form and substance reasonably satisfactory to the Administrative Agent, evidencing that such Subsidiary has been joined as a Guarantor; provided, notwithstanding any failure or delay in the execution of such Joinder Agreement, each such Subsidiary shall be a Guarantor from the time of such designation as a Material Subsidiary. Concurrent with its delivery of the above-referenced Joinder Agreement, each such Material Subsidiary shall also execute an officer’s certificate in the form attached hereto as Exhibit 4.1(b), with the appropriate exhibits thereto, in form and substance reasonably satisfactory to the Administrative Agent. The Joind er Agreement and the officer’s certificate shall all be delivered promptly (and in any event within twenty (20) Business Days after the date of designation of such Subsidiary as a Material Subsidiary) to the Administrative Agent.

For purposes of this Agreement and the other Credit Documents, “Material Subsidiary” shall mean any Subsidiary (a) the revenues of which for the most recent period of four fiscal quarters of the Borrower were greater than 5% of the Borrower’s consolidated revenues for such period or (b) the assets of which as of the last day of the most recently completed period of four fiscal quarters of the Borrower were greater than 5% of Borrower’s consolidated assets as of such date; provided, that if at any time (i) the aggregate amount of the revenues of all Subsidiaries that are not Material Subsidiaries exceeds 10% of the Borrower’s consolidated revenues for the most recent period of four fiscal quarters of the Borrower or (ii) the aggregate amount of the assets of all Subsidiaries that are not Material Subsidiaries exceeds 10% of the Borrower& #146;s consolidated assets as of the last day of the most recently completed period of four fiscal quarters of the Borrower, then the Borrower shall designate sufficient Subsidiaries as “Material Subsidiaries” to eliminate such excess. For purposes of making the determinations required by this definition, revenues and assets of Foreign Subsidiaries shall be converted into Dollars at the rates used in preparing the consolidated balance sheet of the Borrower included in the applicable financial statements of the Borrower. The Borrower agrees that it will promptly notify Administrative Agent in writing if and when any other existing or future Subsidiaries of the Borrower should be added as Guarantors in order to meet the Guarantee Requirement and which Subsidiaries have been so added as Material Subsidiaries.

Notwithstanding the foregoing, and provided no Default or Event of Default shall have occurred and be continuing, if the Borrower provides the Administrative Agent with an officer’s certificate from a Responsible Officer within twenty (20) Business Days after the last day of any fiscal quarter certifying that the Guarantee Requirement and the requirements set forth for a “Material Subsidiary” in the preceding paragraph shall continue to be satisfied at all times notwithstanding the release of a Subsidiary from its status as a “Guarantor”, then the Administrative Agent shall promptly provide a letter in favor of such Subsidiary and the Borrower releasing such Subsidiary from its status as a “Guarantor”.

Each of the Lenders hereby irrevocably appoints Wells Fargo to act on its behalf as the Administrative Agent hereunder and under the other Credit Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent and the Lenders, and neither the Borrower nor any other Credit Party shall have rights as a third party beneficiary of any of such provisions.

Section 8.2 Nature of Duties.

Anything herein to the contrary notwithstanding, none of the bookrunners, arrangers or other agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Credit Documents, except in its capacity, as applicable, as the Administrative Agent or a Lender. Without limiting the foregoing, none of the Lenders or other Persons so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders or other Persons so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as the Administrative Agent.

Section 8.3 Exculpatory Provisions.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Credit Documents. Without limiting the generality of the foregoing, the Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Credit Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Credit Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Credit Document or applicable law; and

(c) shall not, except as expressly set forth herein and in the other Credit Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Credit Party or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 7.2 and 9.1) or (ii) in the absence of its own gross negligence or willful misconduct.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Credit Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Credit Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

Section 8.4 Reliance by the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including, without limitation, any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of any portion of the Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have

received notice to the contrary from such Lender prior to the making of any portion of the Loan. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 8.5 Notice of Default.

The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Administrative Agent has received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give prompt notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; provided, however, that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders except to the extent that this Agreement expressly requires that such action be taken, or not taken, only with the consent or upon the authorization of the Required Lenders, or all of the Lenders, as the case may be.

Section 8.6 Non-Reliance on the Administrative Agent and Other Lenders.

Each Lender expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representation or warranty to it and that no act by the Administrative Agent hereinafter taken, including, without limitation, any review of the affairs of any Credit Party, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of thei r Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Credit Document or any related agreement or any document furnished hereunder or thereunder.

Section 8.7 Indemnification.

The Lenders agree to indemnify the Administrative Agent in its capacity hereunder and its Affiliates and their respective officers, directors, agents and employees (to the extent not reimbursed by the Credit Parties and without limiting the obligation of the Credit Parties to do so), ratably according to their respective ratable portion of the Loan in effect on the date on which indemnification is sought under this Section, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including, without limitation, at any time following the payment of the Credit Party Obligations) be imposed on, incurred by or asserted against any such indemnitee in any way relating to or arising out of any Credit Document or any documents contemplated by or referred to herein or therei n or the transactions contemplated hereby or thereby or any action taken or omitted by any such indemnitee under or in connection with any of the foregoing; provided, however, that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements to the extent resulting from such indemnitee’s gross negligence or willful misconduct, as determined by a court of competent jurisdiction by final and nonappealable

judgment. The agreements in this Section shall survive the termination of this Agreement and payment of the Notes and all other amounts payable hereunder.

Section 8.8 The Administrative Agent in Its Individual Capacity.

The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Credit Parties or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 8.9 Successor Administrative Agent.

The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, or an Affiliate of any such bank. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) ;the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Credit Documents (except that in the case of any Collateral held by the Administrative Agent on behalf of the Lenders under any of the Credit Documents, the retiring Administrative Agent shall continue to hold such Collateral until such time as a successor Administrative Agent is appointed) and (b) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor the Administrative Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as the Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) the Administrative Agent, and the retiring Administrative Agent shall be discha rged from all of its duties and obligations hereunder or under the other Credit Documents (if not already discharged therefrom as provided above in this paragraph). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Credit Documents, the provisions of this Article and Section 9.5 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as the Administrative Agent.

Section 8.10 Collateral and Guaranty Matters.

(a) The Lenders and the Hedging Agreement Providers irrevocably authorize and direct the Administrative Agent:

(i) to release any Lien on any Collateral granted to or held by the Administrative Agent under any Credit Document (A) upon payment in full of all Credit

Party Obligations (other than contingent indemnification obligations for which no claim has been made or cannot be reasonably identified by an Indemnitee based on the then-known facts and circumstances), (B) that is transferred or to be transferred as part of or in connection with any sale or other disposition permitted under Section 6.2, or (C) subject to Section 9.1, if approved, authorized or ratified in writing by the Required Lenders;

(b) In connection with a termination or release pursuant to this Section, the Administrative Agent shall promptly execute and deliver to the applicable Credit Party, at the Borrower’s expense, all documents that the applicable Credit Party shall reasonably request to evidence such termination or release. Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of Collateral, or to release any Guarantor from its obligations under the Guaranty pursuant to this Section.

Section 8.11 Secured Hedging Agreements.

No Hedging Agreement Provider that obtains the benefits of Sections 2.11 and 7.2, any Guaranty or any Collateral by virtue of the provisions hereof or of any Guaranty or any Collateral Document shall have any right to notice of any action or to consent to, direct or object to any action hereunder or under any other Credit Document or otherwise in respect of the Collateral (including, without limitation, the release or impairment of any Collateral) other than in its capacity as a Lender and, in such case, only to the extent expressly provided in the Credit Documents. The Administrative Agent shall not be required to verify the payment of, or that other satisfactory arrangements have been made with respect to, Credit Party Obligations arising under Secured Hedging Agreements unless the Administrative Agent has received written notice of such Credit Party Obligations, together with such supp orting documentation as the Administrative Agent may request, from the applicable Hedging Agreement Provider.

A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.12 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.12 as though it were a Lender.

No Material Litigation

1. In re United Therapeutics Corp. Derivative Litigation, Court of Chancery for the State of Delaware, Consolidated Civil Action No. 4946-CC

Per United Therapeutics’ Quarterly Report on Form 10-Q for the period ending September 30, 2010, as filed via EDGAR on October 28, 2010 (pages 17-18 and 31):

As previously disclosed in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2010 and June 30, 2010, purported shareholders Jeffrey Benison IRA, the Retirement Board of Allegheny County and the Police & Fire Retirement System of the City of Detroit jointly filed a consolidated amended derivative complaint on May 4, 2010 against certain of our directors and named executive officers and us as a nominal defendant. The complaint alleged, among other things, that the individual defendants breached their fiduciary duties to the Company in connection with the adoption of the STAP, the 2008 modification of awards granted under the STAP and the exchange of certain stock options granted under our Amended and Restated Equity Incentive Plan. The plaintiffs sought unspecified monetary damages, purportedly for United Therapeutics Corporation, as w ell as attorneys’ fees and costs and injunctive relief.

On October 25, 2010, the parties entered into a stipulation of settlement. The stipulation provides among other things that, in consideration for the full settlement and release of all of the plaintiffs’ claims, we will: (i) not reprice awards granted under our Amended and Restated Equity Incentive Plan or the STAP in the future without shareholder approval, (ii) cancel 165,214 options granted to our Chief Executive Officer, and (iii) adopt certain corporate governance practices. In connection with the settlement, plaintiffs’ counsel will seek an award of attorneys’ fees from us. The parties have not agreed on the amount of fees, if any, to be awarded to plaintiffs’ counsel, but resolution of this issue is not a condition to settling the claims. The parties will continue to negotiate over attorneys’ fees and, if they do not reach an agreement, w ill seek a decision from the court on this issue. The stipulation of settlement and any proposed award of fees to the plaintiffs’ counsel will be subject to court approval. The court has scheduled a hearing for January 21, 2011 to consider whether to approve the settlement and any proposed fee award. The court also approved the form of Notice of Pendency and Settlement of Action, which is filed as Exhibit 99.1 to this Quarterly Report on Form 10-Q. There can be no assurance that the stipulation of settlement or the fee award, if any, agreed upon by the parties, will be approved by the court. The contemplated settlement is not expected to have a material impact on our statements of financial position or operations.

2. Lifewatch Services, Inc., and Card Guard Scientific Survival, Ltd. v. Medicomp, Inc., and United Therapeutics Corporation, Case No. 6:09-cv-1909-Orl-31DAB

Nature of the Litigation. On November 6, 2009, Lifewatch Services, Inc. and Card Guard Scientific Survival, Ltd. (together, “Lifewatch”) filed a complaint for patent infringement against

Medicomp, Inc., a wholly-owned subsidiary of United Therapeutics Corporation (“Medicomp”). Lifewatch claims that Medicomp’s wireless event monitor device, the CardioPal SAVI wireless, infringes certain claims contained in two patents owned by Lifewatch (U.S. Patent Nos. 7,542,878 B2 and 5,730,143). In addition to its complaint for patent infringement, on November 10, 2009, Lifewatch filed a Motion for Preliminary Injunction to prevent Medicomp from providing services with or selling the CardioPal SAVI wireless device while the patent infringement lawsuit is pending. Lifewatch is seeking to prevent Medicomp from using the device with its event monitoring clients, unspecified damages, other unspecified costs and expenses, and attorneys’ fees and other costs related to litigation.

Progress of the Litigation to Date. Shortly after the lawsuit was filed, Medicomp requested an extension of time to respond to the preliminary injunction motion and in return agreed to delay commercial launch of the CardioPal SAVI wireless device (which was scheduled for January 2010) until the Court ruled on the Motion for Preliminary Injunction. On December 16, 2009, we filed an answer to the complaint and a counterclaim seeking a declaratory judgment that the asserted patent claims were not infringed, were invalid and/or unenforceable. On December 16, 2009, we also filed a response to the Motion for Preliminary Injunction. On January 29, 2010, a hearing on the Motion for Preliminary Injunction was held, and on February 10, 2010 the judge denied Lifewatch’s Motion for Preliminary Injunction. We subsequently requested and were granted a stay of the litigation pending the outcome of reexaminations of all claims of both patents-in-suit by the United States Patent and Trademark Office. The litigation remains stayed and the reexaminations of both patents-in-suit are pending at this time.

Mortgaged Property Modifications

Maryland Mortgaged Property

The United Therapeutics project will include two office buildings, 1040 Spring Street (delivered 12/2009) and 1110 Spring Street (to be delivered 12/2011), each building being ninety feet (90’) high, one on the southwest corner of Cameron Street at its intersection with Spring Street and one at the southeast corner of Cameron Street at its intersection of Spring Street. United Therapeutics has received, through the volumetric abandonment of space in air rights above the public road, rights to construct a connector across Cameron Street to connect the 6th floor of each of the two office buildings.

The building connector will be a private interior conditioned space connecting corridor spanning Cameron Street at the sixth floor between the two office buildings allowing for safe and efficient flow of people working and visiting the project across Cameron Street. This connector enables the two office buildings and the adjacent laboratory facility to function as an integrated whole, effectively transforming two small urban parcels that are divided by a public street into a viable campus for a single owner/user. Each parcel individually would be too small for United Therapeutics’ project requirements; however, the sixth floor connector makes possible the efficient movement and access necessary to support the varying internal functions and requirements of a growing biotechnology company, including stringent “clean room” laboratory environmental controls. With the connector, the two sites function together to support the operational needs of the company.

North Carolina Mortgaged Property

The Phase II Facility Expansion project will expand existing operations in RTP to include additional GMP warehousing space, manufacturing/packaging space, office space, a daycare center and parking deck, along with a mechanical penthouse and various support spaces.

The expansion provides a 3-story building configuration at the Daycare/Office Area and a 2-story building configuration at the manufacturing area with roof level penthouse, all contained in approximately 184,599 square feet of space. In addition to the building expansion, this project will include converting the northern most bay of the existing packaging area currently used as offices into packaging halls (approximately 4,315 square feet). As part of this conversion, limited expansion of the existing second floor mechanical area across this third bay will be included (approximately 3,612 square feet). First and second floor connecting corridors will provide access between the existing and new areas of the facility. The total square footage of work area including new building addition, renovation of existing third bay and new mechanical platform at the second floor level of third bay is approximatel y 192,486 square feet.

The building expansion will also include the addition of a parking deck that will accommodate existing and future UT employee parking demand. This parking deck will accommodate approximately 388 automobiles and is expected to be of a pre-cast design and will include

ground and 4-elevated levels of parking with dual, gated entrance/exit locations, elevator and architectural features that will allow the deck to blend into the building expansion. The parking deck will be located in the area presently occupied by the north parking lots.

The intent of the design will be to provide a cGMP compliant design for the warehouse and manufacturing/packaging areas as well as architecturally blend the new building addition and parking deck with the existing building architecture and match the design features of the original building. Elements of the expansion include:

· The new GMP Warehouse will include an ASRS capable of providing approximately 2,000 pallet storage spaces. The warehouse area will also accommodate secure cage storage areas for labels, clinical and reject products.

· New shipping/receiving area with open office area.

· Eight (8) new packaging halls design with unidirectional flow of materials and low air returns in shared chases between rooms. Support spaces including a new central gowning, restrooms and shower facilities to accommodate new packaging halls and existing manufacturing area, new break room and vending area. Second floor future manufacturing space also included.

· The Daycare Center and outside playground area will be designed to accommodate up to 58 students ranging from infants to afterschool care.

· New office areas designed to accommodate approximately 190 staff that will include restroom facilities, central file storage area, data center, training room, printer room, conference rooms and various gathering seating areas and circular staircase at center of “horseshoe” communicating with all three levels.

· Roof terrace located above second floor office area.

· Rain water collection system that will be used as a source of irrigation for the site. The rain water is expected to be directed to the east side of the site and collected in a 10,000 gallon above ground tank.

· The addition of a fourth 1,000 ton chiller/cooling tower set, including chilled water pump, condenser water pump and controls, process waste neutralization system capable of processing waste from the existing facility and the new expansion and a new 100KW solar panel system planned to be installed above the upper level of the parking deck.

If any or all of the indebtedness under the Documents becomes due and payable or any or all of the other obligations under the Documents are not fully satisfied, each of the Guarantors unconditionally promises to pay such indebtedness and to perform such obligations to or in favor of the Beneficiaries or to their respective order, on demand, together with any and all reasonable expenses which may be incurred by the Beneficiaries in collecting or enforcing any of the Credit Party Obligations. The guaranty set forth in this Guaranty Agreement is a guaranty of timely payment and performance and not of collection.& #160; The word

“indebtedness” is used in this Guaranty Agreement in its most comprehensive sense and includes, without limitation, any and all advances, debts, obligations and liabilities of the Credit Parties under the Documents, including, without limitation, specifically all Credit Party Obligations, arising in connection with any of the Documents, in each case, heretofore, now, or hereafter made, incurred or created under the Documents, whether voluntarily or involuntarily, absolute or contingent, liquidated or unliquidated, determined or undetermined, whether or not such indebtedness under the Documents is from time to time reduced, or extinguished and thereafter increased or incurred, whether any Credit Party may be liable individually or jointly with others under the Documents, whether or not recovery upon such indebtedness under the Documents may be or hereafter become barred by any statute of limitations, a nd whether or not such indebtedness under the Documents may be or hereafter become otherwise unenforceable.

Notwithstanding any provision to the contrary contained in this Guaranty Agreement or in any of the Documents, to the extent the obligations of any Guarantor shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances or transfers) then the obligations of each such Guarantor hereunder shall be limited to the maximum amount that is permissible under applicable law (whether federal or state and including, without limitation, the Bankruptcy Code).

2. No Discharge. The obligations of each of the Guarantors hereunder are absolute, unconditional and irrevocable and will not be discharged by, and this Guaranty Agreement shall remain in full force and effect notwithstanding: (a) the assignment, conveyance or other transfer by any Beneficiary of any or all of its interest under the Documents; or (b) any insolvency, bankruptcy, reorganization, arrangement, composition, liquidation, dissolution, or similar proceedings with respect to any Credit Party; or any other occurrence whatsoever, except timely payment and timely performance in full of all Credit Party Obliga tions in accordance with the terms and conditions of the Documents; or (c) any other circumstances whatsoever which might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety, or which might otherwise limit recourse against any of the Guarantors.

3. Bankruptcy. Additionally, each of the Guarantors unconditionally and irrevocably guarantees jointly and severally the payment and performance of any and all Credit Party Obligations to the Beneficiaries whether or not due, owing or payable upon the occurrence of any Bankruptcy Event or any such event with regard to any Subsidiary or any Guarantor and unconditionally promises to pay and perform such Credit Party Obligations to the Beneficiaries or for the benefit of the Beneficiaries, as applicable (provided, if any such Credit Party Obligation that is a payment obligation is owing to a Lender, such payment shall b e made to the Administrative Agent for the account of the Lender), or order, on demand, in lawful money of the United States. Each of the Guarantors further agrees that to the extent that a Credit Party shall make a payment, perform an obligation or otherwise make a transfer of an interest in any property to or for the benefit of any Beneficiary, which payment, performance or transfer or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, or otherwise is avoided, and/or required to be repaid to the Credit Party, the estate of the Credit Party, a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then to the extent of such avoidance or repayment, the obligation or part thereof intended to be satisfied shall be revived and continued in full force and effect as if said payment, performance or transfer had not been made or effected.

4. Nature of Liability. The liability of each of the Guarantors hereunder is exclusive and independent of any security for or other guaranty of the Credit Party Obligations whether executed by any Guarantor or by any other party, and no Guarantor’s liability hereunder shall be affected or impaired by (a) any direction as to application of payment by any Credit Party or by any other party, or (b) any other continuing or other guaranty, undertaking or maximum liability of a Guarantor or of any other party as to the Credit Party Obligations, or (c) any payment or performance on or in reduction of any such o ther

guaranty or undertaking, or (d) any dissolution, termination or increase, decrease or change in personnel by any Credit Party or by any other party, or (e) any payment or performance made to or for the benefit of any Beneficiary on the Credit Party Obligations which the Beneficiary repays any Credit Party pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and each of the Guarantors waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding.

5. No Subrogation. No Guarantor shall be entitled to be subrogated to any of the rights of any of the Beneficiaries against any Credit Party or any collateral, security or guarantee or right of set-off held by any of the Beneficiaries for the payment or performance of any of the Credit Party Obligations, nor shall any of the Guarantors seek or be entitled to seek any reimbursement from the Credit Parties in respect of payment or performance made by any of the Guarantors hereunder, until all of the Credit Party Obligations are paid and performed in full.

6. Severability. Any provision of this Guaranty Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

7. Independent Obligation. The obligations of each of the Guarantors hereunder are independent of the obligations of any other Credit Party, and a separate action or actions may be brought and prosecuted against each of the Guarantors whether or not action is brought against any other Credit Party and whether or not any other Credit Party is joined in any such action or actions.

8. Authorization. Each of the Guarantors authorizes each of the Beneficiaries without notice or demand (except as shall be required by applicable statute and cannot be waived), and without affecting or impairing its liability hereunder, from time to time to (a) renew, compromise, extend, increase, accelerate or otherwise change the time for payment of, or otherwise change the terms of the Credit Party Obligations or any part thereof in accordance with the Documents, including, without limitation, any increase or decrease of the rate of interest thereon, (b) take and hold security from any of the Guarantors or any other party for the payment and performance of this Guaranty Agreement or the Credit Party Obligations and exchange, enforce waive and release any such security, (c) apply such security and direct the order or manner of sale thereof in accordance with the Documents, (d) release or substitute any one or more endorsers, Guarantors, the Borrower or other obligors and (e) to the extent otherwise permitted herein, release or substitute any Collateral.

9. Reliance. It is not necessary for any Beneficiary to inquire into the capacity or powers of any Credit Party or the officers, directors, members, partners or agents acting or purporting to act on its behalf, and any Credit Party Obligations made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

10. Waiver.

(a) Each of the Guarantors waives any right (except as shall be required by applicable statute and cannot be waived) to require any Beneficiary to (i) proceed against any other Credit Party or any other party, (ii) proceed against or exhaust any security held from any other Credit Party or any other party, or (iii) pursue any other remedy in the Beneficiary’s power whatsoever. Each of the Guarantors waives any defense based on or arising out of any defense of any other Credit Party or any other party other than payment and performance in full of the Credit Party, including, without limitation, any defense based on or arising out of the disability of any

other Credit Party or any other party, or the unenforceability of the Credit Party Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any Credit Party other than payment and performance in full of the Credit Party Obligations. The Administrative Agent may, at its election, foreclose on any security held by any Beneficiary, by one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable (to the extent such sale is permitted by applicable law), or exercise any other right or remedy the Administrative Agent or any other Beneficiary may have against any Credit Party or any other party, or any security, without affecting or impairing in any way the liability of any of the Guarantors hereunder except to the extent the Credit Party Obligations have been paid and performed in full and the Loan Commitments h ave been terminated. Each of the Guarantors waives any defense arising out of any such election by any Beneficiary, even though such election operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of any Guarantor against any other Credit Party or any other party or any security.

(b) Each of the Guarantors waives all presentments, demands for performance, protests and notices, including, without limitation, notices of nonperformance, notice of protest, notices of dishonor, notices of acceptance of this Guaranty Agreement, and notices of the existence, creation or incurring of new or additional Credit Party Obligations. Each of the Guarantors assumes all responsibility for being and keeping itself informed of the financial condition and assets of the Credit Parties, and of all other circumstances bearing upon the risk of nonpayment of the Credit Party Obligations and the nature, scope and extent of the risks which such Guarantor assumes and incurs hereunder, and agrees that no Beneficiary shall have any duty to advise such Guarantor of information known to it regarding such circumstances or risks.

(c) Each of the Guarantors hereby agrees it will not exercise any rights of subrogation which it may at any time otherwise have as a result of this Guaranty Agreement (whether contractual, under Section 509 of the U.S. Bankruptcy Code, or otherwise) to the claims, regarding the Credit Party Obligations, of the Beneficiaries against any other Credit Party and all contractual, statutory or common law rights of reimbursement, contribution or indemnity from any other Credit Party which it may at any time otherwise have as a result of this Guaranty Agreement until such time as the Credit Party Obligations shall have been paid in full and the Loan Commitments have been terminated. Each of the Guarantors hereby further agrees not to exercise any right to enforce any other remedy which any Beneficiary now has or may hereafter have against any Credit Party or any endorser of all or any part of the Credit Party Obligations and any benefit of, and any right to participate in, any security or collateral given to or for the benefit of any Beneficiary to secure payment and performance of the Credit Party Obligations until such time as the Credit Party Obligations shall have been paid and performed in full and the Loan Commitments have been terminated.

(d) The obligations of each of the Guarantors under this Guaranty Agreement shall be paid and performed without demand by any Beneficiary and shall be unconditional irrespective of the genuineness, validity, regularity or enforceability of any of the Documents or any other circumstance which might otherwise constitute a legal or equitable discharge of a surety or a guarantor. Each of the Guarantors hereby waives the benefit of all principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms of this Guaranty Agreement, and agrees that the obligations of each of the Guarantors shall not be affected by any circumstances, whether or not referred to in this Guaranty Agreement, which might oth erwise constitute a legal or equitable discharge of a surety or guarantor. Each of the Guarantors hereby waives the benefits of any right of discharge under any and all statutes or other laws relating to sureties or guarantors and any other rights of sureties and guarantors thereunder. Without

limiting the generality of the foregoing, each of the Guarantors hereby waives diligence, presentment, demand for payment, protest, and all notices which may be required by statute, rule of law or otherwise to preserve intact the Beneficiaries’ rights against each of the Guarantors under this Guaranty Agreement, including, without limitation, notice of acceptance, notice of any amendment of any Document, notice of the occurrence of any default, notice of intent to accelerate, notice of acceleration, notice of dishonor, notice of foreclosure, notice of protest, notice of the incurring by any Credit Party of any of the Credit Party Obligations, and, generally, all demands, notices and other formalities of every kind in connection with this Guaranty Agreement, and all rights to require the Beneficiaries to (i) proceed against the Borrower, (ii) proceed against or exhaust any collateral hel d by any Beneficiary to secure the payment of the Credit Party Obligations, or (iii) pursue any other remedy it may now or hereafter have against any Credit Party.

(e) Without limiting the generality of the foregoing, each of the Guarantors waives all rights and defenses arising out of an election of remedies by any of the Beneficiaries, even though that election of remedies, such as a nonjudicial or judicial foreclosure with respect to security for the Credit Party Obligations, has destroyed each of the Guarantors’ rights of subrogation and reimbursement against the Borrower or any other Credit Party or otherwise. In addition, each of the Guarantors waives all rights and defenses that each of the Guarantors may have because the Credit Party Obligations are secured by real property. This means, among other things:

(i) The Beneficiaries may collect from each of the Guarantors without first foreclosing on any real or personal property collateral pledged by the Borrower.

(ii) If any of the Beneficiaries forecloses on any real property collateral pledged by the Borrower:

(A) The amount of the Credit Party Obligations may be reduced only by the price for which that collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price.

(B) The Beneficiaries may collect from each of the Guarantors even if the Beneficiaries, by foreclosing on the real property collateral, have destroyed any right any of the Guarantors may have to collect from the Borrower.

(f) This is an unconditional and irrevocable waiver of any rights and defenses any of the Guarantors may have because the Credit Party Obligations are secured by real property.

(g) Each of the Guarantors hereby agrees that no Guarantor shall have any right of subrogation or reimbursement against the Borrower or any other Credit Party, no right of subrogation against any collateral or security provided for in the Documents and no right of contribution against any other guarantor or pledgor unless and until the entire Loan and all other amounts and other obligations due and owing or accrued under the Documents have been paid and performed in full. To the extent the waiver by any Guarantor of these rights of subrogation, reimbursement or contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, each of the Guarantors agrees that each of the Guaranto r’s rights of subrogation and reimbursement against the Borrower or any other Credit Party and each of the Guarantor’s right of subrogation against any collateral or security shall be unconditionally junior and subordinate to the Beneficiaries’ rights against the Borrower and the other Credit Parties and to the Beneficiaries’ right, title and interest in such collateral or security, and each of

the Guarantors’ right of contribution against any other guarantor or pledgor shall be unconditionally junior and subordinate to the Beneficiaries’ rights against such other guarantor or Pledgor, unless and until the entire Loan and all other amounts and other obligations due and owing or accrued under the Documents have been paid and performed in full.

11. Limitation on Enforcement. The Beneficiaries agree that this Guaranty Agreement may be enforced only by the action of the Administrative Agent acting upon the instructions of the Required Lenders or, if applicable, the Hedging Agreement Providers (for clarification, the rights of Hedging Agreement Providers shall only arise with respect to obligations under one or more Secured Hedging Agreements that such Hedging Agreement Provider is a party to) and that no Lender or Hedging Agreement Provider shall have any right individually to seek to enforce or to enforce this Guaranty Agreement, it being understood and agreed that such rights and remedies may be exercised solely by the Administrative Agent for the benefit of the Lenders and, if applicable, the Hedging Agreement Providers. The Lenders and the Hedging Agreement Providers further agree that this Guaranty Agreement may not be enforced against any director, officer, employee or stockholder of the Guarantors.

12. Representations and Warranties of each of the Guarantors. Each of the Guarantors hereby represents and warrants as to itself and not as to any other Person that:

(a) it is duly organized and validly existing in good standing under the laws of the jurisdiction of its formation and has the corporate or other such power and authority to carry on its present business and operations, to own or lease its properties and to enter into and perform its obligations under this Guaranty Agreement, and this Guaranty Agreement has been duly authorized, executed and delivered by it and constitutes a legal, valid and binding obligation enforceable against it in accordance with its terms, except as such enforceability may be limited by its bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the rights of creditors generally and by general principles of equity;

(b) the execution and delivery by it of this Guaranty Agreement and compliance by it with all of the provisions hereof do not and will not contravene any law, governmental rule or regulation or any order, writ, injunction or decree of any court or governmental authority or agency applicable to or binding on it or contravene the provisions of, or constitute a default under, its formation documents or any indenture, mortgage, contract or any agreement or instrument to which it is a party or by which it or any of its property may be bound or affected;

(c) no authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body is required for the due execution, delivery or performance by it of this Guaranty Agreement; and

(d) there are no pending or threatened actions or proceedings before any court or administrative agency which could reasonably be expected to have a Material Adverse Effect or otherwise impair its ability to perform its obligations under this Guaranty Agreement.

13. Costs and Expenses. Each of the Guarantors agrees to indemnify and hold each of the Beneficiaries harmless from and against and to pay all actual and reasonable out-of-pocket costs and expenses (including, without limitation, reasonable legal fees and expenses) incurred by or on behalf of any Beneficiary in connection with the collection and/or enforcement of any of the Guarantors’ obligations under this Guaranty Agreement.

14. Miscellaneous. This Guaranty Agreement shall: (a) be binding upon each of the Guarantors, its successors and assigns; (b) inure to the benefit of, and be enforceable by, each of the

Beneficiaries, and its successors and assigns, but shall not, and is not intended to, create rights in any other third parties; (c) not be waived, amended modified, extended, restated, replaced or supplemented without the written consent of each of the Beneficiaries; (d) BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF NEW YORK (WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW); and (e) remain in full force and effect until, and shall be terminated (subject to reinstatement under Section 3 hereof) upon the payment and performance in full by the Borrower of the Credit Party Obligations, in accordance with the terms and provisions of the Documents. All notices to, or requests of, demands on and other communications with any of the Guarantors shall be made in writing and shall be personally delivered, or sent by registered or certified mail, postag e prepaid, or by fax to the following address:
