ARTICLE II. CREDIT FACILITY

Section 2.1. Term Loans.

Subject to the terms and conditions hereof, on the Effective Date, each Lender severally and not jointly agrees to make a Term Loan to the Borrower in the principal amount equal to the amount of such Lender’s Commitment. No later than 1:00 p.m. on the Effective Date, each Lender will make available for the account of its applicable Lending Office to the Agent at the Principal Office, in immediately available funds, the proceeds of the Term Loan to be made by such Lender. Subject to satisfaction of the applicable conditions set forth in Article V. for such borrowing, the Agent will make the proceeds of such borrowing available to the Borrower no later than 2:00 p.m. on the Effective Date and in the manner specified by the Borrower in the

request referred to in Section 5.1.(a)(xvi). The Borrower may not reborrow any portion of the Term Loans once repaid.

Section 2.2. Rates and Payment of Interest on Loans.

(a) Rates. The Borrower promises to pay to the Agent for the account of each Lender interest on the unpaid principal amount of the Term Loan made by such Lender for the period from and including the date of the making of such Loan to but excluding the date such Loan shall be paid in full, at the following per annum rates:

(i) during such periods as such Loan is a Base Rate Loan, at the Base Rate (as in effect from time to time) plus the Applicable Margin; and

(ii) during such periods as such Loan is a LIBOR Loan, at the Adjusted Eurodollar Rate for such Loan for the Interest Period therefor plus the Applicable Margin.

Notwithstanding the foregoing, during the continuance of an Event of Default, the Borrower shall pay to the Agent for the account of each Lender interest at the Post-Default Rate on the outstanding principal amount of any Loan made by such Lender, and on any other amount payable by the Borrower hereunder or under the Note held by such Lender to or for the account of such Lender (including without limitation, accrued but unpaid interest to the extent permitted under Applicable Law).

(b) Payment of Interest. Accrued interest on each Loan shall be payable (i) in the case of a Base Rate Loan, monthly in arrears on the first day of each calendar month, (ii) in the case of a LIBOR Loan, on the last day of each Interest Period therefor, and, if such Interest Period is longer than three months, at three-month intervals following the first day of such Interest Period, and (iii) in the case of any Loan, upon the payment, prepayment or Continuation thereof or the Conversion of such Loan to a Loan of another Type (but only on the principal amount so paid, prepaid, Continued or Converted). Interest payable at the Post-Default Rate shall be payable from time to time on demand. Promptly after the determination of any interest rate provided for herein or any change therein, the Agent shall give notice thereof to the Lenders to which such interest is payable and to the Borrower. All determinations by the Agent of an interest rate hereunder shall be conclusive and binding on the Lenders and the Borrower for all purposes, absent manifest error.

(c) Ratings Change. If the Applicable Margin shall change as a result of a change in the Borrower’s Credit Rating and then within a 90-day period change back to the Applicable Margin in effect at the beginning of such period as a result of another change in such Credit Rating, and (i) if the initial change in the Applicable Margin were an increase, then the Borrower will receive as a credit against its Obligations any incremental interest expense with respect to the Loans for the period during which the increase existed and (ii) if the initial change in the Applicable Margin were a decrease, then the Borrower shall promptly pay to the Agent for the ratable benefit of the Lenders additional interest with respect to the Loans for the period during which the increase existed determined as if such decrease had not occurred.

Section 2.3. Number of Interest Periods.

There may be no more than 3 different Interest Periods outstanding at the same time (for which purpose Interest Periods described in different lettered clauses of the definition of the term “Interest Period” shall be deemed to be different Interest Periods even if they are coterminous).

Section 2.4. Repayment of Loans.

The Borrower shall repay the entire outstanding principal amount of, and all accrued but unpaid interest on, the Term Loans on the Termination Date.

Section 2.5. Prepayments.

Except as otherwise provided in this Section, the Borrower may prepay the Term Loans, in whole or in part, at any time without premium or penalty. The Borrower shall give the Agent at least one Business Day’s prior written notice of the prepayment of the Term Loans. If any of the outstanding principal amount of the Term Loans is prepaid at any time prior to August 25, 2005, the Borrower shall pay to the Agent for the account of the Lenders (a) an amount equal to the following (calculated for the period commencing on the date of such prepayment and ending on August 25, 2005): (i) the principal amount of the Term Loans so prepaid times (ii) a per annum rate equal to the Applicable Margin for LIBOR Loans in effect at the time of such prepayment and (b) any amounts payable pursuant to Section 4.4. in connection with such prepayment. The Borrower acknowledges and agrees that the amount payable by it in connection with the prepayment of the Term Loans is a reasonable calculation of the Lenders’ lost profits in view of the difficulties and impracticality of determining actual damages resulting from the prepayment of the Term Loans.

Section 2.6. Continuation.

So long as no Default or Event of Default shall have occurred and be continuing, the Borrower may on any Business Day, with respect to any LIBOR Loan, elect to maintain such LIBOR Loan or any portion thereof as a LIBOR Loan by selecting a new Interest Period for such LIBOR Loan. Each new Interest Period selected under this Section shall commence on the last day of the immediately preceding Interest Period. Each selection of a new Interest Period shall be made by the Borrower giving to the Agent a Notice of Continuation not later than 11:00 a.m. on the third Business Day prior to the date of any such Continuation. Such notice by the Borrower of a Continuation shall be by telephone or telecopy, confirmed immediately in writing if by telephone, in the form of a Notice of Continuation, specifying (a) the proposed date of such Continuation, (b) the LIBOR Loans and portions thereof subject to such Continuation and (c) the duration of the selected Interest Period, all of which shall be specified in such manner as is necessary to comply with all limitations on Loans outstanding hereunder. Each Notice of Continuation shall be irrevocable by and binding on the Borrower once given. Promptly after receipt of a Notice of Continuation, the Agent shall notify each Lender by telecopy, or other similar form of transmission, of the proposed Continuation. If the Borrower shall fail to select in a timely manner a new Interest Period for any LIBOR Loan in accordance with this Section, or if a Default or Event of Default shall have occurred and be continuing, such Loan will

automatically, on the last day of the current Interest Period therefor, Convert into a Base Rate Loan notwithstanding the first sentence of Section 2.7. or the Borrower’s failure to comply with any of the terms of such Section.

Section 2.7. Conversion.

So long as no Default or Event of Default shall have occurred and be continuing, the Borrower may on any Business Day, upon the Borrower’s giving of a Notice of Conversion to the Agent, Convert all or a portion of a Loan of one Type into a Loan of another Type. Any Conversion of a LIBOR Loan into a Base Rate Loan shall be made on, and only on, the last day of an Interest Period for such LIBOR Loan and, upon Conversion of a Base Rate Loan into a LIBOR Loan, the Borrower shall pay accrued interest to the date of Conversion on the principal amount so Converted. Each such Notice of Conversion shall be given not later than 11:00 a.m. on the Business Day prior to the date of any proposed Conversion into Base Rate Loans and on the third Business Day prior to the date of any proposed Conversion into LIBOR Loans. Promptly after receipt of a Notice of Conversion, the Agent shall notify each Lender by telecopy, or other similar form of transmission, of the proposed Conversion. Subject to the restrictions specified above, each Notice of Conversion shall be by telephone (confirmed immediately in writing) or telecopy in the form of a Notice of Conversion specifying (a) the requested date of such Conversion, (b) the Type of Loan to be Converted, (c) the portion of such Type of Loan to be Converted, (d) the Type of Loan such Loan is to be Converted into and (e) if such Conversion is into a LIBOR Loan, the requested duration of the Interest Period of such Loan. Each Notice of Conversion shall be irrevocable by and binding on the Borrower once given.

Section 2.8. Notes.

(a) Note. The Term Loan made by a Lender shall, in addition to this Agreement, also be evidenced by a promissory note of the Borrower substantially in the form of Exhibit E (each a “Note”), payable to the order of such Lender in a principal amount equal to the amount of its Commitment as originally in effect and otherwise duly completed.

(b) Records. The date, amount, interest rate, Type and duration of Interest Periods (if applicable) of each Loan made by each Lender to the Borrower, and each payment made on account of the principal thereof, shall be recorded by such Lender on its books and such entries shall be binding on the Borrower absent manifest error.

(c) Lost, Stolen, Destroyed or Mutilated Notes. Upon receipt by the Borrower of (i) written notice from a Lender that a Note of such Lender has been lost, stolen, destroyed or mutilated, and (ii) (A) in the case of loss, theft or destruction, an unsecured agreement of indemnity from such Lender in form reasonably satisfactory to the Borrower, or (B) in the case of mutilation, upon surrender and cancellation of such Note, the Borrower shall at its own expense execute and deliver to such Lender a new Note dated the date of such lost, stolen, destroyed or mutilated Note.

Section 2.9. Additional Term Loans.

With the prior consent of the Agent (which consent shall not be unreasonably withheld), the Borrower shall have the right at any time to request increases in the aggregate amount of the Term Loans by providing written notice to the Agent, which notice shall be irrevocable once given. Each such increase in the aggregate amount of the Term Loans must be in an aggregate minimum amount of $10,000,000 and integral multiples of $5,000,000 in excess thereof; provided, that after giving effect to any such increases pursuant to this Section, the aggregate outstanding principal amount of the Term Loans may not exceed $350,000,000. Any such increase shall be effected either by an existing Lender increasing the principal amount of its Term Loan or by a Person becoming a Lender hereunder and making a Term Loan to the Borrower. No existing Lender shall be required to increase the amount of its Term Loan hereunder and any Person becoming a Lender under this Agreement in connection with any such requested increase must be an Eligible Assignee. No increase in the aggregate outstanding principal amount of the Term Loans may be effected under this Section if (x) a Default or Event of Default shall be in existence on the effective date of such increase or (y) any representation or warranty made or deemed made by the Borrower or any other Loan Party in any Loan Document to which any such Loan Party is a party is not (or would not be) true or correct on the effective date of such increase (except for representations or warranties which expressly relate solely to an earlier date). In connection with any increase in the aggregate amount of the Term Loans pursuant to this subsection, (a) any Lender becoming a party hereto shall execute such documents and agreements as the Agent may reasonably request and (b) the Borrower shall make appropriate arrangements so that each new Lender, and any existing Lender increasing the amount of its Term Loan, receives a new or replacement Note, as appropriate, in the amount of such Lender’s Term Loan within 2 Business Days of the effectiveness of the applicable increase.

ARTICLE III. PAYMENTS, FEES AND OTHER GENERAL PROVISIONS

Section 3.1. Payments.

Except to the extent otherwise provided herein, all payments of principal, interest and other amounts to be made by the Borrower under this Agreement or any other Loan Document shall be made in Dollars, in immediately available funds, without deduction, set-off or counterclaim, to the Agent at its Principal Office, not later than 2:00 p.m. on the date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). Subject to Sections 3.2. and 3.3., the Agent, or any Lender for whose account any such payment is made, may (but shall not be obligated to) debit the amount of any such payment which is not made by such time from any special or general deposit account of the Borrower with the Agent or such Lender, as the case may be (with notice to the Borrower, the other Lenders and the Agent). The Borrower shall, at the time of making each payment under this Agreement or any Note, specify to the Agent the amounts payable by the Borrower hereunder to which such payment is to be applied. Each payment received by the Agent for the account of a Lender under this Agreement or any Note shall be paid to such Lender at the applicable Lending Office of such Lender no later than 5:00 p.m. on the date of receipt. If the Agent fails to pay such amount to a Lender as provided in the previous sentence, the Agent shall pay interest on such amount until paid at a rate per annum equal to the Federal Funds Rate from time to time in effect. If the due date of any payment

under this Agreement or any other Loan Document would otherwise fall on a day which is not a Business Day such date shall be extended to the next succeeding Business Day and interest shall be payable for the period of such extension.

Except to the extent otherwise provided herein: (a) each payment or prepayment of principal of Term Loans by the Borrower (including any fees payable under Section 2.5. in connection with any prepayment) shall be made for the account of the Lenders pro rata in accordance with the respective unpaid principal amounts of the Term Loans held by them; (b) each payment of interest on Term Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the amounts of interest on such Loans then due and payable to the respective Lenders; and (c) the Conversion and Continuation of Term Loans of a particular Type (other than Conversions provided for by Section 4.6.) shall be made pro rata among the Lenders according to the amounts of their respective Loans and the then current Interest Period for each Lender’s portion of each Loan of such Type shall be coterminous.

Section 3.3. Sharing of Payments, Etc.

If a Lender shall obtain payment of any principal of, or interest on, any Loan made by it to the Borrower under this Agreement, or shall obtain payment on any other Obligation owing by the Borrower or a Loan Party through the exercise of any right of set-off, banker’s lien or counterclaim or similar right or otherwise or through voluntary prepayments directly to a Lender or other payments made by the Borrower to a Lender not in accordance with the terms of this Agreement and such payment should be distributed to the Lenders pro rata in accordance with Section 3.2. or Section 10.3., as applicable, such Lender shall promptly purchase from the other Lenders participations in (or, if and to the extent specified by such Lender, direct interests in) the Loans made by the other Lenders or other Obligations owed to such other Lenders in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that all the Lenders shall share the benefit of such payment (net of any reasonable expenses which may be incurred by such Lender in obtaining or preserving such benefit) pro rata in accordance with Section 3.2. or Section 10.3. To such end, all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans or other Obligations owed to such other Lenders may exercise all rights of set-off, banker’s lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower.

Section 3.4. Several Obligations.

No Lender shall be responsible for the failure of any other Lender to make a Loan or to perform any other obligation to be made or performed by such other Lender hereunder, and the failure of any Lender to make a Loan or to perform any other obligation to be made or performed

by it hereunder shall not relieve the obligation of any other Lender to make any Loan or to perform any other obligation to be made or performed by such other Lender.

Section 3.5. Minimum Amounts.

(a) Borrowings and Conversions. Each borrowing of Base Rate Loans shall be in an aggregate minimum amount of $1,000,000 and integral multiples of $500,000 in excess thereof. Each borrowing and each Conversion of LIBOR Loans shall be in an aggregate minimum amount of $5,000,000 and integral multiples of $1,000,000 in excess of that amount.

(b) Prepayments. Each voluntary prepayment of Term Loans shall be in an aggregate minimum amount of $1,000,000 and integral multiples of $500,000 in excess thereof (or, if less, the aggregate principal amount of Term Loans then outstanding).

Section 3.6. Computations.

Unless otherwise expressly set forth herein, any accrued interest on any Loan, any Fees or any other Obligations due hereunder shall be computed on the basis of a year of 360 days and the actual number of days elapsed.

Section 3.7. Usury.

In no event shall the amount of interest due or payable on the Loans or other Obligations exceed the maximum rate of interest allowed by Applicable Law and, if any such payment is paid by the Borrower or received by any Lender, then such excess sum shall be credited as a payment of principal, unless the Borrower shall notify the respective Lender in writing that the Borrower elects to have such excess sum returned to it forthwith. It is the express intent of the parties hereto that the Borrower not pay and the Lenders not receive, directly or indirectly, in any manner whatsoever, interest in excess of that which may be lawfully paid by the Borrower under Applicable Law.

Section 3.8. Agreement Regarding Interest and Charges.

The parties hereto hereby agree and stipulate that the only charge imposed upon the Borrower for the use of money in connection with this Agreement is and shall be the interest specifically described in Section 2.2.(a)(i) and (ii). Notwithstanding the foregoing, the parties hereto further agree and stipulate that all agency fees, syndication fees, closing fees, underwriting fees, default charges, late charges, funding or “breakage” charges, prepayment fees, increased cost charges, attorneys’ fees and reimbursement for costs and expenses paid by the Agent or any Lender to third parties or for damages incurred by the Agent or any Lender, are charges made to compensate the Agent or any such Lender for underwriting or administrative services and costs or losses performed or incurred, and to be performed or incurred, by the Agent and the Lenders in connection with this Agreement and shall under no circumstances be deemed to be charges for the use of money. All charges other than charges for the use of money shall be fully earned and nonrefundable when due.

Section 3.9. Statements of Account.

The Agent will account to the Borrower monthly with a statement of Loans, accrued interest, charges and payments made pursuant to this Agreement and the other Loan Documents, and such account rendered by the Agent shall be deemed conclusive upon Borrower absent manifest error. The failure of the Agent to deliver such a statement of accounts shall not relieve or discharge the Borrower from any of its obligations hereunder.

Section 3.10. Defaulting Lenders.

If for any reason any Lender (a “Defaulting Lender”) shall fail or refuse to perform any of its obligations under this Agreement or any other Loan Document to which it is a party within the time period specified for performance of such obligation or, if no time period is specified, if such failure or refusal continues for a period of two Business Days after notice from the Agent, then, in addition to the rights and remedies that may be available to the Agent or the Borrower under this Agreement or Applicable Law, such Defaulting Lender’s right to participate in the administration of the Loans, this Agreement and the other Loan Documents, including without limitation, any right to vote in respect of, to consent to or to direct any action or inaction of the Agent or to be taken into account in the calculation of the Requisite Lenders, shall be suspended during the pendency of such failure or refusal. If a Lender is a Defaulting Lender because it has failed to make timely payment to the Agent of any amount required to be paid to the Agent hereunder (without giving effect to any notice or cure periods), in addition to other rights and remedies which the Agent or the Borrower may have under the immediately preceding provisions or otherwise, the Agent shall be entitled (i) to collect interest from such Defaulting Lender on such delinquent payment for the period from the date on which the payment was due until the date on which the payment is made at the Federal Funds Rate, (ii) to withhold or setoff and to apply in satisfaction of the defaulted payment and any related interest, any amounts otherwise payable to such Defaulting Lender under this Agreement or any other Loan Document and (iii) to bring an action or suit against such Defaulting Lender in a court of competent jurisdiction to recover the defaulted amount and any related interest. Any amounts received by the Agent in respect of a Defaulting Lender’s Loans shall not be paid to such Defaulting Lender and shall be held uninvested by the Agent and either applied against the purchase price of such Loans under the following subsection (b) or paid to such Defaulting Lender upon the Defaulting Lender’s curing of its default.

Section 3.11. Taxes.

(a) Taxes Generally. All payments by the Borrower of principal of, and interest on, the Loans and all other Obligations shall be made free and clear of and without deduction for any present or future excise, stamp or other taxes, fees, duties, levies, imposts, charges, deductions, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding (i) franchise taxes, (ii) any taxes (other than withholding taxes) that would not be imposed but for a connection between the Agent or a Lender and the jurisdiction imposing such taxes (other than a connection arising solely by virtue of the activities of the Agent or such Lender pursuant to or in respect of this Agreement or any other Loan Document), (iii) any taxes imposed on or measured by any Lender’s assets, net income, receipts or branch profits, (iv) any taxes arising after the Agreement Date solely as a result of or attributable to a Lender changing

its designated Lending Office after the date such Lender becomes a party hereto, and (v) any taxes, fees, duties, levies, imposts, charges, deductions, withholdings or other charges to the extent imposed as a result of the failure of the Agent or a Lender, as applicable, to provide and keep current (to the extent legally able) any certificates, documents or other evidence required to qualify for an exemption from, or reduced rate of, any such taxes fees, duties, levies, imposts, charges, deductions, withholdings or other charges or required by the immediately following subsection (c) to be furnished by the Agent or such Lender, as applicable (such non-excluded items being collectively called “Taxes”). If any withholding or deduction from any payment to be made by the Borrower hereunder is required in respect of any Taxes pursuant to any Applicable Law, then the Borrower will:

(i) pay directly to the relevant Governmental Authority the full amount required to be so withheld or deducted;

(ii) promptly forward to the Agent an official receipt or other documentation satisfactory to the Agent evidencing such payment to such Governmental Authority; and

(iii) pay to the Agent for its account or the account of the applicable Lender, as the case may be, such additional amount or amounts as is necessary to ensure that the net amount actually received by the Agent or such Lender will equal the full amount that the Agent or such Lender would have received had no such withholding or deduction been required.

(b) Tax Indemnification. If the Borrower fails to pay any Taxes when due to the appropriate Governmental Authority or fails to remit to the Agent, for its account or the account of the respective Lender, as the case may be, the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and the Lenders for any incremental Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. For purposes of this Section, a distribution hereunder by the Agent or any Lender to or for the account of any Lender shall be deemed a payment by the Borrower.

(c) Tax Forms. Prior to the date that any Lender or participant organized under the laws of a jurisdiction outside the United States of America becomes a party hereto, such Person shall deliver to the Borrower and the Agent such certificates, documents or other evidence, as required by the Internal Revenue Code or Treasury Regulations issued pursuant thereto (including Internal Revenue Service Forms W-8ECI and W-8BEN, as applicable, or appropriate successor forms), properly completed, currently effective and duly executed by such Lender or participant establishing that payments to it hereunder and under the Notes are (i) not subject to United States Federal backup withholding tax or (ii) not subject to United States Federal withholding tax under the Internal Revenue Code because such payment is either effectively connected with the conduct by such Lender or participant of a trade or business in the United States or totally exempt from United States Federal withholding tax by reason of the application of the provisions of a treaty to which the United States is a party or such Lender is otherwise wholly exempt. In addition, any such Lender or participant shall deliver to the Borrower and the Agent further copies of any such certificate, document or other evidence on or before the date that any such certificate, document or other evidence expires or becomes obsolete and after the

occurrence of any event requiring a change in the most recent form previously delivered by it, in each case establishing that payments to it hereunder and under the Notes are (i) not subject to United States Federal backup withholding tax or (ii) not subject to United States Federal withholding tax under the Internal Revenue Code because such payment is either effectively connected with the conduct by such Lender or participant of a trade or business in the United States or totally exempt from United States Federal withholding tax by reason of the application of the provisions of a treaty to which the United States is a party or such Lender or participant, as applicable, is otherwise wholly exempt, unless an event (including, without limitation, any change in Applicable Law) has occurred prior to the date on which any such delivery would otherwise be required which renders all such certificates, documents and other evidence wholly inapplicable or which would prevent such Lender or participant, as applicable, from duly completing and delivering any such certificates, documents or other evidence form with respect to it, and such Lender or participant, as applicable, so advises the Borrower and the Agent in writing.

ARTICLE IV. YIELD PROTECTION, ETC.

Section 4.1. Additional Costs; Capital Adequacy.

(a) Additional Costs. The Borrower shall promptly pay to the Agent for the account of a Lender from time to time such amounts as such Lender may determine to be necessary to compensate such Lender for any costs incurred by such Lender that it determines are attributable to its making or maintaining of any LIBOR Loans or its obligation to make any LIBOR Loans hereunder, any reduction in any amount receivable by such Lender under this Agreement or any of the other Loan Documents in respect of any of such Loans or such obligation or the maintenance by such Lender of capital in respect of its Loans (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from any Regulatory Change that: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any of the other Loan Documents in respect of any of such Loans (other than taxes, fees, duties, levies, imposts, charges, deductions, withholdings or other charges which are excluded from the definition of Taxes pursuant to the first sentence of Section 3.11.(a)); or (ii) imposes or modifies any reserve, special deposit or similar requirements (other than Regulation D of the Board of Governors of the Federal Reserve System or other reserve requirement to the extent utilized in the determination of the Adjusted Eurodollar Rate for such Loan) relating to any extensions of credit or other assets of, or any deposits with or other liabilities of, such Lender, or any commitment of such Lender (including, without limitation, the Commitment of such Lender hereunder); or (iii) has or would have the effect of reducing the rate of return on capital of such Lender to a level below that which such Lender could have achieved but for such Regulatory Change (taking into consideration such Lender’s policies with respect to capital adequacy).

(b) Lender’s Suspension of LIBOR Loans. Without limiting the effect of the provisions of the immediately preceding subsection (a), if, by reason of any Regulatory Change, any Lender either (i) incurs Additional Costs based on or measured by the excess above a specified level of the amount of a category of deposits or other liabilities of such Lender that includes deposits by reference to which the interest rate on LIBOR Loans is determined as

provided in this Agreement or a category of extensions of credit or other assets of such Lender that includes LIBOR Loans or (ii) becomes subject to restrictions on the amount of such a category of liabilities or assets that it may hold, then, if such Lender so elects by notice to the Borrower (with a copy to the Agent), the obligation of such Lender to make or Continue, or to Convert any other Type of Loans into, LIBOR Loans hereunder shall be suspended until such Regulatory Change ceases to be in effect (in which case the provisions of Section 4.6. shall apply).

(c) Notification and Determination of Additional Costs. Each of the Agent and each Lender agrees to notify the Borrower of any event occurring after the Agreement Date entitling the Agent or such Lender to compensation under any of the preceding subsections of this Section as promptly as practicable; provided, however, the failure of the Agent or any Lender to give such notice shall not release the Borrower from any of its obligations hereunder; provided, however, that notwithstanding the foregoing provisions of this Section, the Agent or a Lender, as the case may be, shall not be entitled to compensation for any such amount relating to any period ending more than six months prior to the date that the Agent or such Lender, as applicable, first notifies the Borrower in writing thereof or for any amounts resulting from a change by any Lender of its Lending Office (other than changes required by Applicable Law). The Agent and or such Lender agrees to furnish to the Borrower a certificate setting forth the basis and amount of each request by the Agent or such Lender for compensation under this Section. Absent manifest error, determinations by the Agent or any Lender of the effect of any Regulatory Change shall be conclusive, provided that such determinations are made on a reasonable basis and in good faith.

Section 4.2. Suspension of LIBOR Loans.

Anything herein to the contrary notwithstanding, if, on or prior to the determination of any Adjusted Eurodollar Rate for any Interest Period:

(a) the Agent reasonably determines (which determination shall be conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Adjusted Eurodollar Rate for such Interest Period, or

(b) the Agent reasonably determines (which determination shall be conclusive) that the Adjusted Eurodollar Rate will not adequately and fairly reflect the cost to the Lenders of making or maintaining LIBOR Loans for such Interest Period;

then the Agent shall give the Borrower and each Lender prompt notice thereof and, so long as such condition remains in effect, the Lenders shall be under no obligation to, and shall not, make additional LIBOR Loans, Continue LIBOR Loans or Convert Loans into LIBOR Loans and the Borrower shall, on the last day of each current Interest Period for each outstanding LIBOR Loan, either repay such Loan or Convert such Loan into a Base Rate Loan.

Section 4.3. Illegality.

Notwithstanding any other provision of this Agreement, if it becomes unlawful for any Lender to honor its obligation to make or maintain LIBOR Loans hereunder, then such Lender shall promptly notify the Borrower thereof (with a copy to the Agent) and such Lender’s obligation to make or Continue, or to Convert Loans of any other Type into, LIBOR Loans shall be suspended until such time as such Lender may again make and maintain LIBOR Loans (in which case the provisions of Section 4.6. shall be applicable).

Section 4.4. Compensation.

The Borrower shall pay to the Agent for the account of each Lender, upon the request of such Lender through the Agent, such amount or amounts as shall be sufficient (in the reasonable opinion of such Lender) to compensate it for any loss, cost or expense that such Lender determines is attributable to:

(a) any payment or prepayment (whether mandatory or optional) of a LIBOR Loan, or Conversion of a LIBOR Loan, made by such Lender for any reason (including, without limitation, acceleration) on a date other than the last day of the Interest Period for such Loan; or

(b) any failure by the Borrower for any reason (including, without limitation, the failure of any of the applicable conditions precedent specified in Article V. to be satisfied) to borrow a LIBOR Loan from such Lender on the date for such borrowing, or to Convert a Base Rate Loan into a LIBOR Loan or Continue a LIBOR Loan on the requested date of such Conversion or Continuation.

Upon the Borrower’s request, any Lender requesting compensation under this Section shall provide the Borrower with a statement setting forth the basis for requesting such compensation and the method for determining the amount thereof. Absent manifest error, determinations by any Lender in any such statement shall be conclusive, provided that such determinations are made on a reasonable basis and in good faith.

Section 4.5. Affected Lenders.

If (a) a Lender requests compensation pursuant to Section 3.11. or 4.1., and the Requisite Lenders are not also doing the same, or (b) the obligation of any Lender to make LIBOR Loans or to Continue, or to Convert Base Rate Loans into, LIBOR Loans shall be suspended pursuant to Section 4.1.(b) or 4.3. but the obligation of the Requisite Lenders shall not have been suspended under such Sections, then, so long as there does not then exist any Default or Event of Default, the Borrower may either (i) demand that such Lender (the “Affected Lender”), and upon such demand the Affected Lender shall promptly, assign its Term Loan to an Eligible Assignee subject to and in accordance with the provisions of Section 12.5.(d) for a purchase price equal to the aggregate principal balance of Loans then owing to the Affected Lender plus any accrued but unpaid interest thereon and accrued but unpaid fees owing to the Affected Lender, or (ii) pay to the Affected Lender the aggregate principal balance of Loans then owing to the Affected Lender plus any accrued but unpaid interest thereon and accrued but unpaid fees owing to the Affected

Lender, whereupon the Affected Lender shall no longer be a party hereto or have any rights or obligations hereunder or under any of the other Loan Documents. Each of the Agent and the Affected Lender shall reasonably cooperate in effectuating the replacement of such Affected Lender under this Section, but at no time shall the Agent, such Affected Lender nor any other Lender be obligated in any way whatsoever to initiate any such replacement or to assist in finding an Eligible Assignee. The exercise by the Borrower of its rights under this Section shall be at the Borrower’s sole cost and expenses and at no cost or expense to the Agent, the Affected Lender or any of the other Lenders. The terms of this Section shall not in any way limit the Borrower’s obligation to pay to any Affected Lender compensation owing to such Affected Lender pursuant to Section 3.11. or 4.1.

Section 4.6. Treatment of Affected Loans.

If the obligation of any Lender to make LIBOR Loans or to Continue, or to Convert Base Rate Loans into, LIBOR Loans shall be suspended pursuant to Section 4.1.(b), 4.2. or 4.3., then such Lender’s LIBOR Loans shall be automatically Converted into Base Rate Loans on the last day(s) of the then current Interest Period(s) for LIBOR Loans (or, in the case of a Conversion required by Section 4.1.(b) or 4.3., on such earlier date as such Lender may specify to the Borrower with a copy to the Agent) and, unless and until such Lender gives notice as provided below that the circumstances specified in Section 4.1. or 4.3. that gave rise to such Conversion no longer exist:

(a) to the extent that such Lender’s LIBOR Loans have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Lender’s LIBOR Loans shall be applied instead to its Base Rate Loans; and

(b) all Loans that would otherwise be made or Continued by such Lender as LIBOR Loans shall be made or Continued instead as Base Rate Loans, and all Base Rate Loans of such Lender that would otherwise be Converted into LIBOR Loans shall remain as Base Rate Loans.

If such Lender gives notice to the Borrower (with a copy to the Agent) that the circumstances specified in Section 4.1. or 4.3. that gave rise to the Conversion of such Lender’s LIBOR Loans pursuant to this Section no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist) at a time when LIBOR Loans made by other Lenders are outstanding, then such Lender’s Base Rate Loans shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) for such outstanding LIBOR Loans, to the extent necessary so that, after giving effect thereto, all Loans held by the Lenders holding LIBOR Loans and by such Lender are held pro rata (as to principal amounts, Types and Interest Periods) in accordance with their respective Commitment Percentages.

Section 4.7. Change of Lending Office.

Each Lender agrees that it will use reasonable efforts to designate an alternate Lending Office with respect to any of its Loans affected by the matters or circumstances described in Sections 3.11., 4.1. or 4.3. to reduce the liability of the Borrower or avoid the results provided thereunder, so long as such designation is not disadvantageous to such Lender as determined by

such Lender in its sole discretion, except that such Lender shall have no obligation to designate a Lending Office located in the United States of America.

Section 4.8. Assumptions Concerning Funding of LIBOR Loans.

Calculation of all amounts payable to a Lender under this Article IV. shall be made as though such Lender had actually funded LIBOR Loans through the purchase of deposits in the relevant market bearing interest at the rate applicable to such LIBOR Loans in an amount equal to the amount of the LIBOR Loans and having a maturity comparable to the relevant Interest Period; provided, however, that each Lender may fund each of its LIBOR Loans in any manner it sees fit and the foregoing assumption shall be used only for calculation of amounts payable under this Article IV.

Neither the Borrower, any Subsidiary nor any other Loan Party is in default under its articles of incorporation, bylaws, partnership agreement or other similar organizational documents, and no event has occurred, which has not been remedied, cured or waived: (i) which constitutes a Default or an Event of Default; or (ii) which constitutes, or which with the passage of time, the giving of notice, a determination of materiality, the satisfaction of any condition, or any combination of the foregoing, would constitute, a default or event of default by the Borrower, any Subsidiary or any other Loan Party under any agreement (other than this Agreement) or judgment, decree or order to which the Borrower or any Subsidiary or other Loan Party is a party or by which the Borrower or any Subsidiary or other Loan Party or any of their respective properties may be bound where such default or event of default could, individually or in the aggregate, have a Material Adverse Effect.

(p) Environmental Laws. Each of the Borrower, its Subsidiaries and the other Loan Parties has obtained all Governmental Approvals which are required under Environmental Laws and is in compliance with all terms and conditions of such Governmental Approvals which the failure to obtain or to comply with could reasonably be expected to have a Material Adverse Effect.

Each of the Borrower and each Subsidiary owns or has the right to use, under valid license agreements or otherwise, all material patents, licenses, franchises, trademarks, trademark rights, trade names, trade name rights, trade secrets and copyrights (collectively, “Intellectual Property”) necessary to the conduct of its businesses as now conducted and as contemplated by the Loan Documents, without known conflict with any patent, license, franchise, trademark, trade secret, trade name, copyright, or other proprietary right of any other Person. The Borrower and each such Subsidiary have taken all such steps as

they deem reasonably necessary to protect their respective rights under and with respect to such Intellectual Property. No material claim has been asserted by any Person with respect to the use of any Intellectual Property by the Borrower or any Subsidiary, or challenging or questioning the validity or effectiveness of any Intellectual Property. The use of such Intellectual Property by the Borrower, its Subsidiaries and the other Loan Parties, does not infringe on the rights of any Person, subject to such claims and infringements as do not, in the aggregate, give rise to any liabilities on the part of the Borrower and its Subsidiaries that could reasonably be expected to have a Material Adverse Effect.

(u) Business. As of the Agreement Date, the Borrower and its Subsidiaries are engaged substantially in the business of owning, operating and developing office and industrial assets, together with other business activities incidental thereto, as currently in use at the Properties.

(w) Accuracy and Completeness of Information. No written information, report or other papers or data (excluding financial projections and other forward looking statements) furnished to the Agent or any Lender by, on behalf of, or at the direction of, the Borrower, any Subsidiary or any other Loan Party in connection with or relating in any way to this Agreement, contained any untrue statement of a fact material to the creditworthiness of the Borrower, any Subsidiary or any other Loan Party or omitted to state a material fact necessary in order to make such statements contained therein, in light of the circumstances under which they were made, not misleading. All financial statements furnished to the Agent or any Lender by, on behalf of, or at the direction of, the Borrower, any Subsidiary or any other Loan Party in connection with or relating in any way to this Agreement, present fairly, in accordance with GAAP consistently applied throughout the periods involved, the financial position of the Persons involved as at the date thereof and the results of operations for such periods.

Section 10.2. Remedies Upon Event of Default.

Upon the occurrence of an Event of Default the following provisions shall apply:

(a) Acceleration; Termination of Facilities.

(i) Automatic. Upon the occurrence of an Event of Default specified in Sections 10.1.(f) or 10.1.(g), (A) the principal of, and all accrued interest on, the Loans

and the Notes at the time outstanding, and (B) all of the other Obligations of the Borrower, including, but not limited to, the other amounts owed to the Lenders and the Agent under this Agreement, the Notes or any of the other Loan Documents shall become immediately and automatically due and payable by the Borrower without presentment, demand, protest, or other notice of any kind, all of which are expressly waived by the Borrower.

(ii) Optional. If any other Event of Default shall have occurred and be continuing, the Agent shall, at the direction of the Requisite Lenders (A) declare the principal of, and accrued interest on, the Loans and the Notes at the time outstanding, and (B) all of the other Obligations, including, but not limited to, the other amounts owed to the Lenders and the Agent under this Agreement, the Notes or any of the other Loan Documents to be forthwith due and payable, whereupon the same shall immediately become due and payable without presentment, demand, protest or other notice of any kind, all of which are expressly waived by the Borrower.

(b) Loan Documents. The Requisite Lenders may direct the Agent to, and the Agent if so directed shall, exercise any and all of its rights under any and all of the other Loan Documents.

(c) Applicable Law. The Requisite Lenders may direct the Agent to, and the Agent if so directed shall, exercise all other rights and remedies it may have under any Applicable Law.

(d) Appointment of Receiver. To the extent permitted by Applicable Law, the Agent and the Lenders shall be entitled to the appointment of a receiver for the assets and properties of the Borrower and its Subsidiaries, without notice of any kind whatsoever and without regard to the adequacy of any security for the Obligations or the solvency of any party bound for its payment, to take possession of all or any portion of the business operations of the Borrower and its Subsidiaries and to exercise such power as the court shall confer upon such receiver.

Section 10.3. Allocation of Proceeds.

If an Event of Default shall have occurred and be continuing and maturity of any of the Obligations has been accelerated, all payments received by the Agent under any of the Loan Documents, in respect of any principal of or interest on the Obligations or any other amounts payable by the Borrower hereunder or thereunder, shall be applied in the following order and priority:

(a) amounts due to the Agent and the Lenders in respect of fees and expenses due under Section 12.2.;

Section 10.4. Performance by Agent.

If the Borrower shall fail to perform any covenant, duty or agreement contained in any of the Loan Documents, the Agent may perform or attempt to perform such covenant, duty or agreement on behalf of the Borrower after the expiration of any cure or grace periods set forth herein. In such event, the Borrower shall, at the request of the Agent, promptly pay any amount reasonably expended by the Agent in such performance or attempted performance to the Agent, together with interest thereon at the applicable Post-Default Rate from the date of such expenditure until paid. Notwithstanding the foregoing, neither the Agent nor any Lender shall have any liability or responsibility whatsoever for the performance of any obligation of the Borrower under this Agreement or any other Loan Document.

Section 10.5. Rights Cumulative.

The rights and remedies of the Agent and the Lenders under this Agreement and each of the other Loan Documents shall be cumulative and not exclusive of any rights or remedies which any of them may otherwise have under Applicable Law. In exercising their respective rights and remedies the Agent and the Lenders may be selective and no failure or delay by the Agent or any of the Lenders in exercising any right shall operate as a waiver of it, nor shall any single or partial exercise of any power or right preclude its other or further exercise or the exercise of any other power or right.

ARTICLE XI. THE AGENT

Section 11.1. Authorization and Action.

Each Lender hereby appoints and authorizes the Agent to take such action as contractual representative on such Lender’s behalf and to exercise such powers under this Agreement and the other Loan Documents as are specifically delegated to the Agent by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. Not in limitation of the foregoing, each Lender authorizes and directs the Agent to enter into the Loan Documents for the benefit of the Lenders. Each Lender hereby agrees that, except as otherwise set forth herein, any action taken by the Requisite Lenders in accordance with the provisions of this Agreement or the Loan Documents, and the exercise by the Requisite Lenders of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders. Nothing herein shall be construed to deem the Agent a

trustee or fiduciary for any Lender nor to impose on the Agent duties or obligations other than those expressly provided for herein. At the request of a Lender, the Agent will forward to such Lender copies or, where appropriate, originals of the documents delivered to the Agent pursuant to this Agreement or the other Loan Documents. The Agent will also furnish to any Lender, upon the request of such Lender, a copy of any certificate or notice furnished to the Agent by the Borrower, any Loan Party or any other Affiliate of the Borrower, pursuant to this Agreement or any other Loan Document not already delivered to such Lender pursuant to the terms of this Agreement or any such other Loan Document. As to any matters not expressly provided for by the Loan Documents (including, without limitation, enforcement or collection of any of the Obligations), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Requisite Lenders (or all of the Lenders if explicitly required under any other provision of this Agreement), and such instructions shall be binding upon all Lenders and all holders of any of the Obligations; provided, however, that, notwithstanding anything in this Agreement to the contrary, the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to this Agreement or any other Loan Document or Applicable Law. Not in limitation of the foregoing, the Agent shall not exercise any right or remedy it or the Lenders may have under any Loan Document upon the occurrence of a Default or an Event of Default unless the Requisite Lenders have so directed the Agent to exercise such right or remedy.

Section 11.2. Agent’s Reliance, Etc.

Notwithstanding any other provisions of this Agreement or any other Loan Documents, neither the Agent nor any of its directors, officers, agents, employees or counsel shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for its or their own gross negligence or willful misconduct. Without limiting the generality of the foregoing, the Agent: (a) may treat the payee of any Note as the holder thereof until the Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to the Agent; (b) may consult with legal counsel (including its own counsel or counsel for the Borrower or any other Loan Party), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender or any other Person and shall not be responsible to any Lender or any other Person for any statements, warranties or representations made by any Person in or in connection with this Agreement or any other Loan Document; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of any of this Agreement or any other Loan Document or the satisfaction of any conditions precedent under this Agreement or any Loan Document on the part of the Borrower or other Persons or inspect the property, books or records of the Borrower or any other Person; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Loan Document, any other instrument or document furnished pursuant thereto or any collateral covered thereby or the perfection or priority of any Lien in favor of the Agent on behalf of the Lenders in any such collateral; and (f) shall incur no liability under or in respect of this Agreement or any other Loan Document by acting upon any notice, consent,

certificate or other instrument or writing (which may be by telephone or telecopy) believed by it to be genuine and signed, sent or given by the proper party or parties.

Section 11.3. Notice of Defaults.

The Agent shall not be deemed to have knowledge or notice of the occurrence of a Default or Event of Default unless the Agent has received notice from a Lender or the Borrower referring to this Agreement, describing with reasonable specificity such Default or Event of Default and stating that such notice is a “notice of default.” If any Lender (excluding the Lender which is also serving as the Agent) becomes aware of any Default or Event of Default, it shall promptly send to the Agent such a “notice of default.” Further, if the Agent receives such a “notice of default”, the Agent shall give prompt notice thereof to the Lenders.

Section 11.4. Wachovia as Lender.

Wachovia, as a Lender, shall have the same rights and powers under this Agreement and any other Loan Document as any other Lender and may exercise the same as though it were not the Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include Wachovia in each case in its individual capacity. Wachovia and its affiliates may each accept deposits from, maintain deposits or credit balances for, invest in, lend money to, act as trustee under indentures of, serve as financial advisor to, and generally engage in any kind of business with, the Borrower, any other Loan Party or any other affiliate thereof as if it were any other bank and without any duty to account therefor to the other Lenders. Further, the Agent and any affiliate may accept fees and other consideration from the Borrower for services in connection with this Agreement and otherwise without having to account for the same to the other Lenders.

Section 11.5. Approvals of Lenders.

All communications from the Agent to any Lender requesting such Lender’s determination, consent, approval or disapproval (a) shall be given in the form of a written notice to such Lender, (b) shall be accompanied by a description of the matter or issue as to which such determination, approval, consent or disapproval is requested, or shall advise such Lender where information, if any, regarding such matter or issue may be inspected, or shall otherwise describe the matter or issue to be resolved, (c) shall include, if reasonably requested by such Lender and to the extent not previously provided to such Lender, written materials and a summary of all oral information provided to the Agent by the Borrower in respect of the matter or issue to be resolved, and (d) shall include the Agent’s recommended course of action or determination in respect thereof. Each Lender shall reply promptly, but in any event within 10 Business Days (or such lesser or greater period as may be specifically required under the Loan Documents) of receipt of such communication. Except as otherwise provided in this Agreement and except with respect to items requiring the unanimous consent or approval of the Lenders under Section 12.6., unless a Lender shall give written notice to the Agent that it specifically objects to the recommendation or determination of the Agent (together with a written explanation of the reasons behind such objection) within the applicable time period for reply, such Lender shall be deemed to have conclusively approved of or consented to such recommendation or determination.

Section 11.6. Lender Credit Decision, Etc.

Each Lender expressly acknowledges and agrees that neither the Agent nor any of its officers, directors, employees, agents, counsel, attorneys-in-fact or other affiliates has made any representations or warranties as to the financial condition, operations, creditworthiness, solvency or other information concerning the business or affairs of the Borrower, any other Loan Party, any Subsidiary or any other Person to such Lender and that no act by the Agent hereafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any such representation or warranty by the Agent to any Lender. Each Lender acknowledges that it has, independently and without reliance upon the Agent, any other Lender or counsel to the Agent, or any of their respective officers, directors, employees and agents, and based on the financial statements of the Borrower, the Subsidiaries or any other Affiliate thereof, and inquiries of such Persons, its independent due diligence of the business and affairs of the Borrower, the Loan Parties, the Subsidiaries and other Persons, its review of the Loan Documents, the legal opinions required to be delivered to it hereunder, the advice of its own counsel and such other documents and information as it has deemed appropriate, made its own credit and legal analysis and decision to enter into this Agreement and the transaction contemplated hereby. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, any other Lender or counsel to the Agent or any of their respective officers, directors, employees and agents, and based on such review, advice, documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking or not taking action under the Loan Documents. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Agent under this Agreement or any of the other Loan Documents, the Agent shall have no duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, financial and other condition or creditworthiness of the Borrower, any other Loan Party or any other Affiliate thereof which may come into possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or other Affiliates. Each Lender acknowledges that the Agent’s legal counsel in connection with the transactions contemplated by this Agreement is only acting as counsel to the Agent and is not acting as counsel to such Lender.

Section 11.7. Indemnification of Agent.

Each Lender agrees to indemnify the Agent (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so) pro rata in accordance with such Lender’s respective Commitment Percentage, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may at any time be imposed on, incurred by, or asserted against the Agent (in its capacity as Agent but not as a Lender) in any way relating to or arising out of the Loan Documents, any transaction contemplated hereby or thereby or any action taken or omitted by the Agent under the Loan Documents (collectively, “Indemnifiable Amounts”); provided, however, that no Lender shall be liable for any portion of such Indemnifiable Amounts to the extent resulting from the Agent’s gross negligence or willful misconduct or if the Agent fails to follow the written direction of the Requisite Lenders unless such failure is pursuant to the reasonable advice of counsel of which the Lenders have received notice. Without limiting the generality of the foregoing but subject to the preceding proviso,

each Lender agrees to reimburse the Agent (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so) promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees of the counsel(s) of the Agent’s own choosing) incurred by the Agent in connection with the preparation, negotiation, execution, or enforcement of, or legal advice with respect to the rights or responsibilities of the parties under, the Loan Documents, any suit or action brought by the Agent to enforce the terms of the Loan Documents and/or collect any Obligations, any “lender liability” suit or claim brought against the Agent and/or the Lenders, and any claim or suit brought against the Agent and/or the Lenders arising under any Environmental Laws. Such out-of-pocket expenses (including counsel fees) shall be advanced by the Lenders on the request of the Agent notwithstanding any claim or assertion that the Agent is not entitled to indemnification hereunder upon receipt of an undertaking by the Agent that the Agent will reimburse the Lenders if it is actually and finally determined by a court of competent jurisdiction that the Agent is not so entitled to indemnification. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder or under the other Loan Documents and the termination of this Agreement. If the Borrower shall reimburse the Agent for any Indemnifiable Amount following payment by any Lender to the Agent in respect of such Indemnifiable Amount pursuant to this Section, the Agent shall share such reimbursement on a ratable basis with each Lender making any such payment.

Section 11.8. Successor Agent.

The Agent may resign at any time as Agent under the Loan Documents by giving written notice thereof to the Lenders and the Borrower. The Agent may be removed as Agent under the Loan Documents for good cause by all of the Lenders (other than the Lender then acting as the Agent) upon 30 days’ prior notice. Upon any such resignation or removal, the Requisite Lenders (other than the Lender then acting as Agent, in the case of the removal of the Agent under the immediately preceding sentence) shall have the right to appoint a successor Agent which appointment shall, provided no Default or Event of Default shall have occurred and be continuing, be subject to the Borrower’s approval, which approval shall not be unreasonably withheld or delayed (except that the Borrower shall, in all events, be deemed to have approved each Lender and its affiliates as a successor Agent). If no successor Agent shall have been so appointed in accordance with the immediately preceding sentence, and shall have accepted such appointment, within 30 days after the resigning Agent’s giving of notice of resignation or the Lenders’ removal of the resigning Agent, then the resigning or removed Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a Lender, if any Lender shall be willing to serve, and otherwise shall be a commercial bank having total combined assets of at least $50,000,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under the Loan Documents. After any Agent’s resignation or removal hereunder as Agent, the provisions of this Article XI. shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents.

Section 11.9. Titled Agents.

Each of the Titled Agents in each such respective capacity, assumes no responsibility or obligation hereunder, including, without limitation, for servicing, enforcement or collection of any of the Loans, nor any duties as an agent hereunder for the Lenders. The titles of “Sole Lead Arranger”, “Syndication Agent”, “Co-Documentation Agent” and “Managing Agent” are solely honorific and imply no fiduciary responsibility on the part of the Titled Agents to the Agent, the Borrower or any Lender and the use of such titles does not impose on the Titled Agents any duties or obligations greater than those of any other Lender or entitle the Titled Agents to any rights other than those to which any other Lender is entitled.

or, as to each party at such other address as shall be designated by such party in a written notice to the other parties delivered in compliance with this Section. All such notices and other communications shall be effective (i) if mailed, when received; (ii) if telecopied, when transmitted; or (iii) if hand delivered, when delivered. Notwithstanding the immediately preceding sentence, all notices or communications to the Agent or any Lender under Article II

shall be effective only when actually received. Neither the Agent nor any Lender shall incur any liability to the Borrower (nor shall the Agent incur any liability to the Lenders) for acting upon any telephonic notice referred to in this Agreement which the Agent or such Lender, as the case may be, believes in good faith to have been given by a Person authorized to deliver such notice or for otherwise acting in good faith hereunder.

Section 12.2. Expenses.

The Borrower agrees (a) to pay or reimburse the Agent for all of its reasonable out-of-pocket costs and expenses incurred in connection with the preparation, negotiation and execution of, and any amendment, supplement or modification to, any of the Loan Documents (including due diligence expenses and travel expenses relating to closing), and the consummation of the transactions contemplated thereby, including the reasonable fees and disbursements of counsel to the Agent, (b) to pay or reimburse the Agent and the Lenders for all their costs and expenses incurred in connection with the enforcement or preservation of any rights under the Loan Documents, including the reasonable fees and disbursements of their respective counsel (including the allocated fees and expenses of in-house counsel) and any payments in indemnification or otherwise payable by the Lenders to the Agent pursuant to the Loan Documents, (c) to pay, and indemnify and hold harmless the Agent and the Lenders from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any failure to pay or delay in paying, documentary, stamp, excise and other similar taxes, if any, which may be payable or determined to be payable in connection with the execution and delivery of any of the Loan Documents, or consummation of any amendment, supplement or modification of, or any waiver or consent under or in respect of, any Loan Document and (d) to the extent not already covered by any of the preceding subsections, to pay or reimburse the Agent and the Lenders for all their costs and expenses incurred in connection with any bankruptcy or other proceeding of the type described in Sections 10.1.(f) or 10.1.(g), including the reasonable fees and disbursements of counsel to the Agent and any Lender, whether such fees and expenses are incurred prior to, during or after the commencement of such proceeding or the confirmation or conclusion of any such proceeding. If the Borrower shall fail to pay any amounts required to be paid by it pursuant to this Section, the Agent and/or the Lenders may pay such amounts on behalf of the Borrower and either deem the same to be Loans outstanding hereunder or otherwise Obligations owing hereunder.

Section 12.3. Setoff.

Subject to Section 3.3. and in addition to any rights now or hereafter granted under Applicable Law and not by way of limitation of any such rights, the Agent, each Lender and each Participant is hereby authorized by the Borrower, at any time or from time to time during the continuance of an Event of Default, without prior notice to the Borrower or to any other Person, any such notice being hereby expressly waived, but in the case of a Lender or Participant subject to receipt of the prior written consent of the Agent exercised in its sole discretion, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other indebtedness at any time held or owing by the Agent, such Lender or any affiliate of the Agent or such Lender, to or for the credit or the account of the Borrower against and on account of any of the Obligations, irrespective of whether or not any or all of the Loans and all

other Obligations have been declared to be, or have otherwise become, due and payable as permitted by Section 10.2., and although such obligations shall be contingent or unmatured. Promptly following any such set-off the Agent shall notify the Borrower thereof and of the application of such set-off, provided that the failure to give such notice shall not invalidate such set-off.

Section 12.4. Litigation; Jurisdiction; Other Matters; Waivers.

(a) EACH PARTY HERETO ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE LENDERS, THE AGENT AND THE BORROWER HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO ARISING OUT OF THIS AGREEMENT, THE NOTES, OR ANY OTHER LOAN DOCUMENT OR BY REASON OF ANY OTHER SUIT, CAUSE OF ACTION OR DISPUTE WHATSOEVER BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS OF ANY KIND OR NATURE.

(b) EACH OF THE BORROWER, THE AGENT AND EACH LENDER HEREBY AGREES THAT THE FEDERAL DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK OR ANY STATE COURT LOCATED IN NEW YORK, NEW YORK, SHALL HAVE NONEXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS, PERTAINING DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE LOANS, THE NOTES OR ANY OTHER LOAN DOCUMENT OR TO ANY MATTER ARISING HEREFROM OR THEREFROM. THE BORROWER AND EACH OF THE LENDERS EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS. EACH PARTY FURTHER WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM AND EACH AGREES NOT TO PLEAD OR CLAIM THE SAME. THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY THE AGENT OR ANY LENDER OR THE ENFORCEMENT BY THE AGENT OR ANY LENDER OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY OTHER APPROPRIATE JURISDICTION.

(c) THE PROVISIONS OF THIS SECTION HAVE BEEN CONSIDERED BY EACH PARTY WITH THE ADVICE OF COUNSEL AND WITH A FULL UNDERSTANDING OF THE LEGAL CONSEQUENCES THEREOF, AND SHALL SURVIVE THE PAYMENT OF THE LOANS AND ALL OTHER AMOUNTS PAYABLE

HEREUNDER OR UNDER THE OTHER LOAN DOCUMENTS, AND THE TERMINATION OF THIS AGREEMENT.

Section 12.5. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, except that the Borrower may not assign or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of all Lenders and any such assignment or other transfer to which all of the Lenders have not so consented shall be null and void.

(b) Any Lender may make, carry or transfer Loans at, to or for the account of any of its branch offices or the office of an affiliate of such Lender except to the extent such transfer would result in increased costs to the Borrower.

(c) Any Lender may at any time grant to one or more banks or other financial institutions (each a “Participant”) participating interests in the Obligations owing to such Lender. Except as otherwise provided in Section 12.3., no Participant shall have any rights or benefits under this Agreement or any other Loan Document. In the event of any such grant by a Lender of a participating interest to a Participant, such Lender shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement pursuant to which any Lender may grant such a participating interest shall provide that such Lender shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided, however, such Lender may agree with the Participant that it will not, without the consent of the Participant, agree to (i) increase, or extend the term or extend the time or waive any requirement for the reduction or termination of, such Lender’s Term Loan, (ii) extend the date fixed for the payment of principal of or interest on the Loans or portions thereof owing to such Lender, (iii) reduce the amount of any such payment of principal, (iv) reduce the rate at which interest is payable thereon or (v) release any Guarantor (except as otherwise permitted under Section 7.12.(b)). An assignment or other transfer which is not permitted by subsection (d) or (e) below shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this subsection (c).

(d) Any Lender may with the prior written consent of the Agent and, so long as no Default or Event of Default shall have occurred and be continuing, the Borrower (which consent, in each case, shall not be unreasonably withheld), assign to one or more Eligible Assignees (each an “Assignee”) all or a portion of the Term Loan owing to such Lender and its other rights and obligations under this Agreement and the Notes; provided, however, (i) no such consent by the Borrower shall be required in the case of any assignment by a Lender to (A) any affiliate of such Lender, (B) another Lender, or (C) any affiliate of another Lender; (ii) any partial assignment shall be in an amount at least equal to $1,000,000 and integral multiples of $1,000,000 in excess thereof and after giving effect to such assignment the assigning Lender, holds a Note having an aggregate outstanding principal balance, of at least $1,000,000 and integral multiples of

$1,000,000 in excess thereof; provided, however, the amount limitations of this clause (ii) shall not apply to any assignment by a Lender to (A) any affiliate of such Lender, (B) another Lender, (C) any affiliate of another Lender or (D) an Approved Fund; and (iii) each such assignment shall be effected by means of an Assignment and Acceptance Agreement. Upon execution and delivery of such instrument and payment by such Assignee to such transferor Lender of an amount equal to the purchase price agreed between such transferor Lender and such Assignee, such Assignee shall be deemed to be a Lender party to this Agreement as of the effective date of the Assignment and Acceptance Agreement and shall have all the rights and obligations of a Lender with a Term Loan as set forth in such Assignment and Acceptance Agreement, and the transferor Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this subsection (d), the transferor Lender, the Agent and the Borrower shall make appropriate arrangements so that new Notes are issued to the Assignee and such transferor Lender, as appropriate. In connection with any such assignment, the transferor Lender shall pay to the Agent an administrative fee for processing such assignment in the amount of $3,500.

(e) The Agent shall maintain at the Principal Office a copy of each Assignment and Acceptance Agreement delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Term Loan of each Lender from time to time (the “Register”). The Agent shall give each Lender and the Borrower notice of the assignment by any Lender of its rights as contemplated by this Section. The Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register and copies of each Assignment and Acceptance Agreement shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice to the Agent. Upon its receipt of an Assignment and Acceptance Agreement executed by an assigning Lender, together with each Note subject to such assignment, the Agent shall, if such Assignment and Acceptance Agreement has been completed and if the Agent receives the processing and recording fee described in subsection (d) above, (i) accept such Assignment and Acceptance Agreement, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower.

(f) In addition to the assignments and participations permitted under the foregoing provisions of this Section, any Lender may assign and pledge all or any portion of its Loans and its Notes to any Federal Reserve Bank as collateral security pursuant to Regulation A and any Operating Circular issued by such Federal Reserve Bank, and such Loans and Notes shall be fully transferable as provided therein. No such assignment shall release the assigning Lender from its obligations hereunder.

(g) A Lender may furnish any information concerning the Borrower, any other Loan Party or any of their respective Subsidiaries in the possession of such Lender from time to time to Assignees and Participants (including prospective Assignees and Participants) subject to compliance with Section 12.8.

(h) Anything in this Section to the contrary notwithstanding, no Lender may assign or participate any interest in any Loan held by it hereunder to the Borrower, any other Loan Party or any of their respective Affiliates or Subsidiaries.

(i) Each Lender agrees that, without the prior written consent of the Borrower and the Agent, it will not make any assignment hereunder in any manner or under any circumstances that would require registration or qualification of, or filings in respect of, any Loan or Note under the Securities Act or any other securities laws of the United States of America or of any other jurisdiction.

Section 12.6. Amendments.

Except as otherwise expressly provided in this Agreement, any consent or approval required or permitted by this Agreement or any other Loan Document to be given by the Lenders may be given, and any term of this Agreement or of any other Loan Document may be amended, and the performance or observance by the Borrower or any other Loan Party or any Subsidiary of any terms of this Agreement or such other Loan Document or the continuance of any Default or Event of Default may be waived (either generally or in a particular instance and either retroactively or prospectively) with, but only with, the written consent of the Requisite Lenders (and, in the case of an amendment to any Loan Document, the written consent of the Borrower). Notwithstanding the foregoing, no amendment, waiver or consent shall, unless in writing, and signed by all of the Lenders (or the Agent at the written direction of the Lenders), do any of the following: (i) increase the principal amount of a Lender’s Term Loan (except for any increase in the amount of a Lender’s Term Loan effectuated pursuant to Section 2.9.), or increase the aggregate amount of the Term Loans in excess of the limit set forth in Section 2.9., or otherwise subject the Lenders to any additional obligations; (ii) reduce the principal of, or interest rates that have accrued or that will be charged on the outstanding principal amount of, any Loans or Fees or other Obligations; (iii) reduce the amount of any Fees payable hereunder; (iv) postpone any date fixed for any payment of any principal of, or interest on, any Loans or any other Obligations; (v) change the Commitment Percentages (except as a result of any increase in the aggregate amount of the Term Loans effectuated pursuant to Section 2.9. or as a result of the Borrower’s exercise of its rights under Section 4.5.) or amend or otherwise modify the provisions of Section 3.2.; (vi) amend Section 9.1.(e) or waive any Default or Event of Default occurring under Section 10.1.(c) resulting from a violation of such Section; (vii) amend the definition of “Unencumbered Asset Value” (or any of the definitions used in such definition or the percentages or rates used in the calculation thereof); (viii) modify the definition of the term “Requisite Lenders” or, except as otherwise provided in the immediately following clause (x), modify in any other manner the number or percentage of the Lenders required to make any determinations or waive any rights hereunder or to modify any provision hereof, including without limitation, any modification of this Section if such modification would have such effect; or (ix) release any Guarantor from its obligations under the Guaranty (except as otherwise permitted under Section 7.12.(b)). In addition, no amendment, waiver or consent shall, unless in writing, and signed by the Supermajority Lenders (or the Agent at the written direction of the Supermajority Lenders), do any of the following: (x) amend or otherwise modify the provisions of, or waive any Event of Default occurring under, Section 10.1.(m) or (y) modify the definition of the term “Supermajority Lenders”. Further, no amendment, waiver or consent unless in

writing and signed by the Agent, in addition to the Lenders required hereinabove to take such action, shall affect the rights or duties of the Agent under this Agreement or any of the other Loan Documents. No waiver shall extend to or affect any obligation not expressly waived or impair any right consequent thereon and any amendment, waiver or consent shall be effective only in the specific instance and for the specific purpose set forth therein. No course of dealing or delay or omission on the part of the Agent or any Lender in exercising any right shall operate as a waiver thereof or otherwise be prejudicial thereto. Except as otherwise explicitly provided for herein or in any other Loan Document, no notice to or demand upon the Borrower shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

Section 12.7. Nonliability of Agent and Lenders.

The relationship between the Borrower and the Lenders and the Agent shall be solely that of borrower and lender. Neither the Agent nor any Lender shall have any fiduciary responsibilities to the Borrower and no provision in this Agreement or in any of the other Loan Documents, and no course of dealing between or among any of the parties hereto, shall be deemed to create any fiduciary duty owing by the Agent or any Lender to any Lender, the Borrower, any Subsidiary or any other Loan Party. Neither the Agent nor any Lender undertakes any responsibility to the Borrower to review or inform the Borrower of any matter in connection with any phase of the Borrower’s business or operations.

Section 12.8. Confidentiality.

Except as otherwise provided by Applicable Law, the Agent and each Lender shall utilize all non-public information obtained pursuant to the requirements of this Agreement which has been identified as confidential or proprietary by the Borrower in accordance with its customary procedure for handling confidential information of this nature and in accordance with safe and sound banking practices but in any event may make disclosure: (a) to any of their respective affiliates (provided they shall agree to keep such information confidential in accordance with the terms of this Section); (b) as reasonably requested by any bona fide Assignee, Participant or other transferee in connection with the contemplated transfer of any Term Loan or participations therein as permitted hereunder (provided they shall agree to keep such information confidential in accordance with the terms of this Section); (c) as required or requested by any Governmental Authority or representative thereof or pursuant to legal process or in connection with any legal proceedings; (d) to the Agent’s or such Lender’s independent auditors and other professional advisors (provided they shall be notified of the confidential nature of the information); (e) after the happening and during the continuance of an Event of Default, to any other Person, in connection with the exercise by the Agent or the Lenders of rights hereunder or under any of the other Loan Documents; and (f) to the extent such information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Agent or any Lender on a nonconfidential basis from a source other than the Borrower or any Affiliate.

Section 12.9. Indemnification.

(a) The Borrower shall and hereby agrees to indemnify, defend and hold harmless the Agent, any affiliate of the Agent and each of the Lenders and their respective directors, officers, shareholders, agents, employees and counsel (each referred to herein as an “Indemnified Party”)

from and against any and all losses, costs, claims, damages, liabilities, deficiencies, judgments or expenses of every kind and nature (including, without limitation, amounts paid in settlement, court costs and the fees and disbursements of counsel incurred in connection with any litigation, investigation, claim or proceeding or any advice rendered in connection therewith, but excluding losses, costs, claims, damages, liabilities, deficiencies, judgments or expenses indemnification in respect of which is specifically covered by Section 3.11. or 4.1. or expressly excluded from the coverage of such Sections) incurred by an Indemnified Party in connection with, arising out of, or by reason of, any suit, cause of action, claim, arbitration, investigation or settlement, consent decree or other proceeding (the foregoing referred to herein as an “Indemnity Proceeding”) which is in any way related directly or indirectly to: (i) this Agreement or any other Loan Document or the transactions contemplated thereby; (ii) the making of any Loans hereunder; (iii) any actual or proposed use by the Borrower of the proceeds of the Loans; (iv) the Agent’s or any Lender’s entering into this Agreement; (v) the fact that the Agent and the Lenders have established the credit facility evidenced hereby in favor of the Borrower; (vi) the fact that the Agent and the Lenders are creditors of the Borrower and have or are alleged to have information regarding the financial condition, strategic plans or business operations of the Borrower and the Subsidiaries; (vii) the fact that the Agent and the Lenders are material creditors of the Borrower and are alleged to influence directly or indirectly the business decisions or affairs of the Borrower and the Subsidiaries or their financial condition; (viii) the exercise of any right or remedy the Agent or the Lenders may have under this Agreement or the other Loan Documents; provided, however, that the Borrower shall not be obligated to indemnify any Indemnified Party for any acts or omissions of such Indemnified Party in connection with matters described in this clause (viii) to the extent that such acts or omissions constitute gross negligence or willful misconduct of such Indemnified Person; or (ix) any violation or non-compliance by the Borrower or any Subsidiary of any Applicable Law (including any Environmental Law) including, but not limited to, any Indemnity Proceeding commenced by (A) the Internal Revenue Service or state taxing authority or (B) any Governmental Authority or other Person under any Environmental Law, including any Indemnity Proceeding commenced by a Governmental Authority or other Person seeking remedial or other action to cause the Borrower or its Subsidiaries (or its respective properties) (or the Agent and/or the Lenders as successors to the Borrower) to be in compliance with such Environmental Laws.

(b) The Borrower’s indemnification obligations under this Section shall apply to all Indemnity Proceedings arising out of, or related to, the foregoing whether or not an Indemnified Party is a named party in such Indemnity Proceeding. In this connection, this indemnification shall cover all costs and expenses of any Indemnified Party in connection with any deposition of any Indemnified Party or compliance with any subpoena (including any subpoena requesting the production of documents). This indemnification shall, among other things, apply to any Indemnity Proceeding commenced by other creditors of the Borrower or any Subsidiary, any shareholder of the Borrower or any Subsidiary (whether such shareholder(s) are prosecuting such Indemnity Proceeding in their individual capacity or derivatively on behalf of the Borrower), any account debtor of the Borrower or any Subsidiary or by any Governmental Authority.

(c) This indemnification shall apply to any Indemnity Proceeding arising during the pendency of any bankruptcy proceeding filed by or against the Borrower and/or any Subsidiary.

(d) All out-of-pocket fees and expenses of, and all amounts paid to third-persons by, an Indemnified Party shall be advanced by the Borrower at the request of such Indemnified Party notwithstanding any claim or assertion by the Borrower that such Indemnified Party is not entitled to indemnification hereunder upon receipt of an undertaking by such Indemnified Party that such Indemnified Party will reimburse the Borrower if it is actually and finally determined by a court of competent jurisdiction that such Indemnified Party is not so entitled to indemnification hereunder.

(e) An Indemnified Party may conduct its own investigation and defense of, and may formulate its own strategy with respect to, any Indemnified Proceeding covered by this Section and, as provided above, all costs and expenses incurred by such Indemnified Party shall be reimbursed by the Borrower. No action taken by legal counsel chosen by an Indemnified Party in investigating or defending against any such Indemnified Proceeding shall vitiate or in any way impair the obligations and duties of the Borrower hereunder to indemnify and hold harmless each such Indemnified Party; provided, however, that (i) if the Borrower is required to indemnify an Indemnified Party pursuant hereto and (ii) the Borrower has provided evidence reasonably satisfactory to such Indemnified Party that the Borrower has the financial wherewithal to reimburse such Indemnified Party for any amount paid by such Indemnified Party with respect to such Indemnified Proceeding, such Indemnified Party shall not settle or compromise any such Indemnified Proceeding without the prior written consent of the Borrower (which consent shall not be unreasonably withheld or delayed).

(f) If and to the extent that the obligations of the Borrower hereunder are unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment and satisfaction of such obligations which is permissible under Applicable Law.

(g) The Borrower’s obligations hereunder shall survive any termination of this Agreement and the other Loan Documents and the payment in full in cash of the Obligations, and are in addition to, and not in substitution of, any other of their obligations set forth in this Agreement or any other Loan Document to which it is a party.

Section 12.10. Termination; Survival.

At such time as all Obligations (other than obligations which survive as provided in the following sentence) have been paid and satisfied in full, this Agreement shall terminate. The indemnities to which the Agent and the Lenders are entitled under the provisions of Sections 3.11., 4.1., 4.4., 11.7., 12.2. and 12.9. and any other provision of this Agreement and the other Loan Documents, and the provisions of Section 12.4., shall continue in full force and effect and shall protect the Agent and the Lenders (i) notwithstanding any termination of this Agreement, or of the other Loan Documents, against events arising after such termination as well as before and (ii) at all times after any such party ceases to be a party to this Agreement with respect to all matters and events existing on or prior to the date such party ceased to be a party to this Agreement.

Section 12.11. Severability of Provisions.

Any provision of this Agreement which 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 remainder of such provision or the remaining provisions or affecting the validity or enforceability of such provision in any other jurisdiction.

Section 12.12. GOVERNING LAW.

THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED, AND TO BE FULLY PERFORMED, IN SUCH STATE.

Section 12.13. Counterparts.

This Agreement and any amendments, waivers, consents or supplements may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all of which counterparts together shall constitute but one and the same instrument.

Section 12.14. Obligations with Respect to Loan Parties.

The obligations of the Borrower to direct or prohibit the taking of certain actions by the other Loan Parties as specified herein shall be absolute and not subject to any defense the Borrower may have that the Borrower does not control such Loan Parties.

Section 12.15. Limitation of Liability.

Neither the Agent nor any Lender, nor any affiliate, officer, director, employee, attorney, or agent of the Agent or any Lender shall have any liability with respect to, and the Borrower hereby waives, releases, and agrees not to sue any of them upon, any claim for any special, indirect, incidental, or consequential damages suffered or incurred by the Borrower in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents. The Borrower hereby waives, releases, and agrees not to sue the Agent or any Lender or any of the Agent’s or any Lender’s affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or financed hereby.

Section 12.16. Entire Agreement.

This Agreement, the Notes, and the other Loan Documents referred to herein embody the final, entire agreement among the parties hereto and supersede any and all prior commitments, agreements, representations, and understandings, whether written or oral, relating to the subject matter hereof and thereof and may not be contradicted or varied by evidence of prior,

contemporaneous, or subsequent oral agreements or discussions of the parties hereto. There are no oral agreements among the parties hereto.

Section 12.17. Construction.

The Agent, the Borrower and each Lender acknowledge that each of them has had the benefit of legal counsel of its own choice and has been afforded an opportunity to review this Agreement and the other Loan Documents with its legal counsel and that this Agreement and the other Loan Documents shall be construed as if jointly drafted by the Agent, the Borrower and each Lender.

SECTION 12.18. LIABILITY OF TRUSTEES, ETC.

THE PARTIES HERETO ACKNOWLEDGE AND AGREE AS FOLLOWS:

THE AMENDED AND RESTATED DECLARATION OF TRUST ESTABLISHING THE BORROWER, DATED JULY 1, 1994, A COPY OF WHICH, TOGETHER WITH ALL AMENDMENTS THERETO (THE “DECLARATION”), IS DULY FILED IN THE OFFICE OF THE STATE DEPARTMENT OF ASSESSMENTS AND TAXATION OF MARYLAND, PROVIDES THAT THE NAME “HRPT PROPERTIES TRUST” REFERS TO THE TRUSTEES UNDER THE DECLARATION COLLECTIVELY AS TRUSTEES, BUT NOT INDIVIDUALLY OR PERSONALLY, AND THAT NO TRUSTEE, OFFICER, SHAREHOLDER, EMPLOYEE OR AGENT OF THE BORROWER SHALL BE HELD TO ANY PERSONAL LIABILITY, JOINTLY OR SEVERALLY, FOR ANY OBLIGATION OF, OR CLAIM AGAINST, THE BORROWER. ALL PERSONS DEALING WITH THE BORROWER, IN ANY WAY, SHALL LOOK ONLY TO THE ASSETS OF THE BORROWER FOR THE PAYMENT OF ANY SUM OR THE PERFORMANCE OF ANY OBLIGATION. THE PROVISIONS OF THIS SECTION SHALL NOT LIMIT ANY OBLIGATIONS OF ANY LOAN PARTY OTHER THAN THE BORROWER.

FORM OF OPINION OF COUNSEL

[LETTERHEAD OF BORROWER’S COUNSEL]

February 25, 2004

Wachovia Bank, National Association, as Agent

for the Lenders under the Term Loan Agreement referred to below

301 South College Street, NC0172

Charlotte, North Carolina 28288

The Additional Addressees set

forth on Schedule I hereto

Ladies and Gentlemen:

This opinion is delivered to you pursuant to Section 5.1(a)(iv) of the Term Loan Agreement dated as of February 25, 2004 (the “Term Loan Agreement”) by and among HRPT Properties Trust, a real estate investment trust organized under the laws of the State of Maryland (the “Borrower”), the Lenders party thereto, Wachovia Bank, National Association, as Agent, and the other parties thereto. We have acted as counsel for the Borrower and each of the Guarantors listed on Schedule II hereto (collectively with Borrower, the “Loan Parties”) in connection with the Term Loan Agreement and the other Loan Documents identified below. Capitalized terms used in this opinion, unless otherwise defined herein, shall have the meanings assigned thereto in the Term Loan Agreement.

For purposes of the opinions expressed below, we have examined executed counterparts of:

(i) the Term Loan Agreement;

(ii) the Notes; and

(iii) the Guaranty.

The Term Loan Agreement, the Notes and the Guaranty are collectively referred to herein as the “Loan Documents”.

In addition, we have examined the originals or copies of the declaration of trust, limited partnership agreement, articles of incorporation, articles of organization, by-laws and operating agreements, as applicable, of each Loan Party (collectively, the “Organizational Documents” for such Loan Party), certain resolutions of the board of directors or other governing body of each Loan Party

F-1-1

and such other records, agreements and instruments of the Loan Parties, certificates of public officials and of officers of the Loan Parties and such other documents and records, and such matters of law, as we have deemed necessary as a basis for the opinions hereinafter expressed.

In connection with this opinion, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies, which facts we have not independently verified. As to various facts material to the opinions set forth herein, we have relied without independent verification upon factual representations made by the Borrower in the Term Loan Agreement, upon certificates of public officials and upon facts certified to us by officers of the Loan Parties, as the case may be.

For purposes of the opinions expressed herein, we have assumed that (i) each Lender and Titled Agent, each Loan Party organized under the laws of a jurisdiction other than Delaware, New York or Massachusetts and each other party (other than Loan Parties organized under the laws of Delaware, New York or Massachusetts) to the Loan Documents and to all other documents, agreements and instruments examined by us (A) are corporations or other entities validly existing under the laws of the jurisdiction of its organization and (B) have all requisite power and authority (corporate and other), and have taken all necessary action to enter into and perform all of its obligations under the Loan Documents or such other documents, agreements and instruments to which they are a party, and (ii) each Loan Document and each such other document, agreement and instrument are and will be the valid, binding and enforceable obligations of each party thereto, other than the Loan Parties. We express no opinion upon the application of any federal, state or local statute, law, rule or regulation (including without limitation any Federal or state banking, truth-in-lending or other similar credit statute, law, rule or regulation) to the authority of any Lender or Titled Agent to enter into and to carry out its respective obligations under the Loan Documents.

Statements herein as to the truth of certain matters “to our knowledge” or as to matters “known to us” and similar statements refer to the knowledge consciously held by the individual lawyers in our firm who have participated in the negotiation and drafting of the Loan Documents without independent investigation and do not necessarily refer to such knowledge as might be acquired by a review of all of our files with respect to matters involving the Loan Parties or by interviews with all present and former members and associates of our firm. Without limiting the generality of the foregoing, please be advised that in connection with the opinions expressed in paragraphs 6 and 8 below, we have not conducted any searches of dockets of any courts or other Governmental Authorities.

Barry M. Portnoy is a trustee of the Borrower, a trustee and/or director of the Guarantors and a director and 50% shareholder of REIT Management & Research Inc. (“RMR”), a Delaware corporation which is the Borrower’s advisor. Jennifer B. Clark is a Senior Vice President of the Borrower and an officer of several of the Guarantors and of RMR. Mr. Portnoy and Ms. Clark are retired members of this firm. Inquiries concerning matters which may be known to Mr. Portnoy or Ms. Clark should be directed to them.

F-1-2

This opinion is limited to the laws of the Commonwealth of Massachusetts, the laws of the State of New York (with respect to paragraphs 5 and 11 only), the General Corporation Law and the Revised Uniform Limited Partnership Act of the State of Delaware and the federal laws of the United States of America, and we express no opinions with respect to the law of any other jurisdiction. We express no opinion as to the effect of the law of any jurisdiction other than the State of New York wherein any Lender Party may be located or wherein enforcement of the Term Loan Agreement or any of the other Loan Documents may be sought that limits the rates of interest legally chargeable or collectible.

Our opinions set forth in paragraphs 1 and 3 below with respect to the existence, good standing or qualification of the Borrower and the Guarantors in various jurisdictions, other than the Guarantors which, as set forth on Schedule II hereto, are Massachusetts “nominee trusts,” are based solely on certificates to that effect issued by the Secretaries of State of such jurisdictions and heretofore delivered to the Agent. Our opinion set forth in paragraph 2 below with respect to the existence of each Guarantor which, as set forth on Schedule II hereto, is a Massachusetts “nominee trust,” is based solely on a certificate to such effect from its trustee or trustees heretofore delivered to the Agent.

Our opinions set forth below are subject to the following general qualifications:

(a) Our opinion set forth in paragraph 5 below is subject to (i) the effect of applicable bankruptcy, insolvency, receivership, reorganization, moratorium, liquidation or other similar laws (including, without limitation, all laws relating to fraudulent transfers) relating to or affecting creditors’ rights generally, and (ii) general principles of equity (including the availability of equitable remedies and further including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing), regardless of whether considered in a proceeding in equity or at law. Further, pursuant to such equitable principles, Section 3 of the Guaranty, which provides, among other things, that the liability of the Guarantors shall not be affected by amendments to or other changes in the Loan Documents, might be enforceable only to the extent that such amendments or other changes were not so material as to constitute a new contract among the parties.

(b) We express no opinion as to provisions granting indemnity or rights of contribution (to the extent limited by federal or state securities laws or public policy).

(c) We express no opinion as to (i) any provision of a Loan Document to the effect that provisions therein may only be amended or waived in writing, to the extent that an oral agreement modifying such provisions has been entered into, or (ii) any provision of any Loan Document for the payment of an increased rate of interest after maturity or a default, late charges or similar payments (or any guaranty thereof) to the extent such interest, charges or payments constitute a penalty or for the payment of interest after judgment in excess of any applicable statutory rate (or any guaranty thereof).

(d) The enforceability of the Loan Documents may be limited (i) by general principles of contract law that where less than all of an agreement is enforceable, the balance is

F-1-3

enforceable only when the unenforceable portion is not an essential part of the agreed exchange, and (ii) by the exercise of judicial discretion regarding the determination of damages and entitlement to attorneys’ fees and other costs.

(e) We express no opinion as to whether any of the Guarantors may guarantee or otherwise become liable for indebtedness incurred by the Borrower or another Loan Party except to the extent that the guaranteeing Guarantor may be determined to have benefited from the incurrence of such indebtedness by such other entity, and we express no opinion as to whether the amount of such benefit may be determined by any measure other than the extent to which proceeds of the indebtedness incurred by such other entity are directly or indirectly made available to such Guarantor for its corporate, partnership or analogous purposes. For purposes of this opinion, we have relied on the certification of each Loan Party that the transactions contemplated by the Loan Documents are necessary or convenient to the conduct, promotion or attainment of the business of such Loan Party.

(f) We express no opinion as to (i) whether a state court outside of the State of New York or a Federal court would give effect to the choice of New York law provided for in the Loan Documents or to the provisions of Section 12.4(b) of the Term Loan Agreement or Section 17(b) of the Guaranty (or any comparable provision of any other Loan Document), or (ii) the provisions of Section 12.4(b) of the Term Loan Agreement or Section 17(b) of the Guaranty (or any comparable provision of any other Loan Document) to the extent they relate to the subject matter jurisdiction of any Federal court.

Based upon and subject to the foregoing, we are of the opinion that:

1. Each Guarantor which, as set forth on Schedule II hereto, is a corporation or limited partnership organized under the laws of the State of Delaware or the Commonwealth of Massachusetts (i) is validly existing and in good standing as a corporation or limited partnership under the laws of the State of Delaware or the Commonwealth of Massachusetts, as the case may be, and (ii) has the corporate or partnership (as the case may be) power to execute and deliver, and to perform its obligations under, the Guaranty, and to own and use its material assets and conduct its business in all material respects as presently conducted.

2. Each Guarantor which, as set forth on Schedule II hereto, is a Massachusetts “nominee trust” (i) exists as a trust under the laws of the Commonwealth of Massachusetts and (ii) has the trust power to execute, deliver and perform the Guaranty and to own and lease its material assets and conduct its business in all material respects as presently conducted.

3. The Borrower is qualified to transact business as a foreign real estate investment trust or business trust in the jurisdictions listed beside its name on Schedule III hereto. Each Guarantor is qualified to transact business as a foreign real estate investment trust, business trust, corporation or limited partnership, as applicable, in the respective jurisdictions listed beside its name on such Schedule III.

F-1-4

4. The execution and delivery of the Guaranty by each Guarantor which is organized under the laws of the State of Delaware or the Commonwealth of Massachusetts and the performance by such Guarantor of its obligations thereunder have been duly authorized by all necessary corporate, partnership or trust (as the case may be) action on the part of such Guarantor.

5. Each Loan Party has duly executed and delivered the Loan Documents to which it is a party, and each Loan Document is a valid and binding obligation of each Loan Party which is a party thereto, enforceable against each such Loan Party in accordance with its terms.

6. The execution and delivery by each of the Loan Parties of the Loan Documents to which it is a party and the consummation by such Loan Parties of the transactions thereunder do not, and if each of the Loan Parties were now to perform its obligations under such Loan Documents in accordance with the terms thereof, such performance would not, result in any material:

(a) violation of such Loan Party’s respective Organizational Documents;

(b) violation of any existing federal, Massachusetts or New York constitution or statute or any existing federal, Massachusetts or New York governmental regulation or rule to which such Loan Party or its assets are subject;

(c) breach or violation of or default under any of the agreements, instruments, indentures or other documents listed on Schedule 6.1(g) or Schedule 6.1(h) to the Term Loan Agreement to which such Loan Party is a party or by which such Loan Party or its assets is bound;

(d) creation or imposition of any contractual lien or security interest in, on or against the assets of any Loan Party under any of the agreements, instruments, indentures or other documents listed on Schedule 6.1(g) or Schedule 6.1(h) to the Term Loan Agreement to which such Loan Party is a party or by which such Loan Party or its respective assets is bound; or

(e) violation of any judicial or administrative decree, writ, judgment or order to which, to our knowledge, any Loan Party or its respective assets are subject.

7. The execution, delivery and performance by each of the Loan Parties of each Loan Document to which it is a party, and the consummation by the Loan Parties of the transactions thereunder, do not and will not require any registration with, consent or approval of, or notice to, or other action to, with or by, any Governmental Authority of the United States of America, the Commonwealth of Massachusetts or the State of New York or by any Governmental Authority of the State of Delaware pursuant to the General Corporation Law or the Revised Uniform Limited Partnership Act of the State of Delaware.

8. To our knowledge there is no (i) undischarged judgment which has been entered against any Loan Party, the satisfaction of which, or (ii) action, suit, proceeding or investigation before or by any federal or state court, agency or other governmental or administrative board or body, pending or threatened, against any of the Loan Parties in which an unfavorable decision, ruling or finding, would

F-1-5

materially adversely affect the business or properties or financial condition of the Loan Parties, considered as a consolidated whole, or the validity or enforceability of any of the Loan Documents.

9. None of the Loan Parties is, or, after giving effect to the Loans, if made on the date hereof, would be, subject to regulation under the Public Utility Holding Company Act of 1935, the Federal Power Act or the Investment Company Act of 1940, each as amended, or to any federal or Massachusetts statute or regulation specifically limiting its ability to incur indebtedness for borrowed money.

10. Assuming that Borrower applies the proceeds of the Loans as provided in the Term Loan Agreement, the transactions contemplated by the Loan Documents do not violate the provisions of Regulations T, U or X of the Federal Reserve Board.

11. The consideration to be paid to the Lender for the financial accommodations to be provided to the Loan Parties pursuant to the Term Loan Agreement does not violate any law of the State of New York relating to interest and usury.

This opinion is furnished to you solely for your benefit in connection with the consummation of the transactions contemplated by the Term Loan Agreement and may not be relied upon by any other person or entity, other than an Assignee of a Lender, or for any other purpose without our express, prior written consent. All of the opinions set forth herein are rendered as of the date hereof, and we assume no obligation to update such opinions to reflect any facts or circumstances which may hereafter come to our attention or any changes in the law which may hereafter occur.

Very truly yours,

Re: HRPT Properties Trust: $250,000,000 Senior Unsecured Term Loan

Ladies and Gentlemen:

We have served as counsel for HRPT Properties Trust, a Maryland real estate investment trust (the “Borrower”), and [Update following list of Guarantors as needed] Hub Acquisition Trust, Hub LA Properties Trust, Hub Properties Trust, Hub RI Properties Trust, Hub Woodmont Investment Trust, 1735 Market Street Properties Trust, Nine Penn Center Properties Trust, Research Park Properties Trust, and Rosedale Properties Trust, each a Maryland real estate investment trust and a wholly owned direct or indirect subsidiary of the Borrower (collectively, the “Trust Subsidiaries”), Hub Realty College Park I, LLC, a Maryland limited liability company and a wholly owned indirect subsidiary of the Borrower (the “LLC”), and Nine Penn Center Associates, L.P., a Pennsylvania limited partnership and an indirect subsidiary of the Borrower (the “LP,” and, together with the Trust Subsidiaries and the LLC, collectively referred to as the “Guarantors”), in connection with certain matters of Maryland and Pennsylvania law arising out of the Term Loan Agreement, dated as of February 25, 2004 (the “Term Loan Agreement”), by and among the Borrower, the Lenders named therein (collectively, the “Lenders”), Wachovia Bank, National Association, as Administrative Agent (the “Agent”), and the other Financial Institutions party thereto, pursuant to which the Agent and the Lenders are making available to the Borrower $250,000,000 senior unsecured term loans. This firm did not participate in the negotiation or drafting of the Loan Documents (as defined herein).

F-2-1

This opinion is being delivered to you in connection with Section 5.1(a)(iv) of the Term Loan Agreement. Unless otherwise defined herein, capitalized terms used herein have the meanings given to them in the Term Loan Agreement.

In connection with our representation of the Borrower and the Guarantors (collectively referred to herein as the “Loan Parties”), and as a basis for the opinion hereinafter set forth, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (hereinafter collectively referred to as the “Documents”):

14. The Term Loan Agreement, certified as of the date hereof by an officer of the Borrower;

15. [ ] Notes, dated as of February 25, 2004 (the “Notes”), made by the Borrower to various Lenders, certified as of the date hereof by an officer of the Borrower;

16. The Guaranty, dated as of February 25, 2004 (the “Guaranty,” and together with the Term Loan Agreement and the Notes, collectively referred to as the “Loan Documents”), made by the Guarantors in favor of the Agent, certified as of the date hereof by an officer of each of the Guarantors;

17. A Certificate executed by an officer of the Borrower, an officer of each of the Trust Subsidiaries and an officer of the Manager, dated as of the date hereof; and

18. Such other documents and matters as we have deemed necessary or appropriate to express the opinion set forth below, subject to the assumptions, limitations and qualifications stated herein.

In expressing the opinion set forth below, we have assumed the following:

1. Each individual executing any of the Documents, whether on behalf of such

individual or another person, is legally competent to do so.

2. Each individual executing any of the Documents on behalf of a party (other than the

Loan Parties, excluding the Manager on behalf of the LLC) is duly authorized to do so.

F-2-3

3. Each of the parties (other than the Loan Parties) executing any of the Documents has duly and validly executed and delivered each of the Documents to which such party is a signatory, and such party’s obligations set forth therein are legal, valid and binding and are enforceable in accordance with all stated terms.

4. Any Documents submitted to us as originals are authentic. Any Documents submitted to us as certified or photostatic copies conform to the original documents. All signatures on all Documents are genuine. All public records reviewed or relied upon by us or on our behalf are true and complete. All representations, warranties, statements and information contained in the Documents are true and complete. There has been no oral or written modification of or amendment to any of the Documents, and there has been no waiver of any provision of any of the Documents, by action or omission of the parties or otherwise.

5. All necessary action has been taken under Delaware law and the organizational documents of the Manager to validly authorize the execution, delivery and performance by the Manager, in its capacity as the managing member of the LLC, of the Loan Documents to which the LLC is a party.

The phrase “known to us” is limited to the actual knowledge, without independent inquiry, of the lawyers at our firm who have performed legal services in connection with the issuance of this opinion.

Based upon the foregoing, and subject to the assumptions, limitations and qualifications stated herein, it is our opinion that:

1. The Borrower is a real estate investment trust duly organized and validly existing under and by virtue of the laws of the State of Maryland and is in good standing with the SDAT. The Borrower has trust power to execute and deliver, and to perform its obligations under, the Loan Documents to which it is a party, and to conduct the business of owning and leasing commercial office properties.

2. Each of the Trust Subsidiaries is a real estate investment trust duly organized and validly existing under and by virtue of the laws of the State of Maryland and is in good standing with the SDAT. Each of the Trust Subsidiaries has trust power to execute and deliver, and to perform its obligations under, the Loan Documents to which it is a party, and to conduct the business of owning and leasing commercial office properties.

3. The LLC is a limited liability company duly formed and validly existing under and by virtue of the laws of the State of Maryland and is in good standing with the SDAT. The LLC has limited liability company power to execute and deliver, and to perform its obligations under, the Loan Documents to which it is a party, and to conduct the business of owning and leasing commercial office properties.

F-2-4

4. The LP is a limited partnership duly formed and validly subsisting under the laws of the Commonwealth of Pennsylvania. The LP has limited partnership power to execute and deliver, and to perform its obligations under, the Loan Documents to which it is a party, and to conduct the business of owning and leasing commercial office properties.

5. Each of the Loan Parties has duly authorized the execution and delivery of the Loan Documents to which it is a party and the performance of such Loan Party’s obligations thereunder. Each of the Loan Parties has duly executed and, so far as is known to us, delivered, the Loan Documents to which it is a party.

6. Neither (a) the execution and delivery by the Borrower of the Loan Documents to which it is a party nor (b) the performance of its obligations thereunder will violate any Maryland law or any existing Maryland governmental regulation or rule to which the Borrower or its assets are subject or the Declaration of Trust or Bylaws of the Borrower.

7. Neither (a) the execution and delivery by each Trust Subsidiary of the Loan Documents to which it is a party nor (b) the performance of its obligations thereunder will violate any Maryland law or any existing Maryland governmental regulation or rule to which such Trust Subsidiary or its assets are subject or the Declaration of Trust or Bylaws of such Trust Subsidiary.

8. Neither (a) the execution and delivery by the LLC of the Loan Documents to which it is a party nor (b) the performance of its obligations thereunder will violate any Maryland law or any existing Maryland governmental regulation or rule to which the LLC or its assets are subject or the Articles of Organization or the Operating Agreement.

9. Neither (a) the execution and delivery by the LP of the Loan Documents to which it is a party nor (b) the performance of its obligations thereunder will violate any Pennsylvania law or any existing Pennsylvania governmental regulation or rule to which the LP or its assets are subject or the Partnership Certificate or the Partnership Agreement.

10. No consent or approval of, registration with, notice to or other action by, any Maryland governmental authority which has not been obtained, made or waived, if any, is required for any Loan Party’s execution and delivery of, or performance of its obligations under, the Loan Documents to which it is a party.

11. No consent or approval of, registration with, notice to or other action by, any Pennsylvania governmental authority which has not been obtained, made or waived, if any, is required for the LP’s execution and delivery of, or performance of its obligations under, the Loan Documents to which it is a party.

We draw to your attention the existence of the following two Pennsylvania statutes in connection with the fact that loans under the Term Loan Agreement bear floating rates of interest:

(i) Section 911 of the Pennsylvania “Crime Code,” 18 Pa. C.S.A. § 911, enacted by the Act of December 6, 1972, P.L. 1482. Section 911 of the Crime Code bears a close resemblance to certain of the provisions of the Federal Racketeer Influenced and Corrupt Organizations Act of 1970, 18 U.S.C. §§1961-1968, commonly known as RICO, and is referred to hereinafter as the “Pennsylvania RICO Act.” The Pennsylvania RICO Act provides, among other things, that it is a criminal offense, punishable as a felony, to “use or invest, directly or indirectly...in the acquisition of any interest in, or the establishment or operation of, any enterprise...” any income collected in full or partial satisfaction of a loan made “at a rate of interest exceeding 25% per annum....”

(ii) The Act of December 29, 1982, P.L. 1671, 18 Pa. C.S.A. § 4806.1 et seq. (superseded volume) (the “Criminal Usury Statute”). The Criminal Usury Statute provides, among other things, that it is a criminal offense, punishable as a felony, to engage in, “charging, taking or receiving any money...on the loan...of any money...at a rate exceeding thirty-six percent per annum....”

The Criminal Usury Statute may have been repealed, but the manner in which the repeal was enacted leaves the matter subject to uncertainty.

Both the Pennsylvania RICO Act and the Criminal Usury Statute appear to be intended by the legislature to apply only to racketeering and loan sharking type activities, and not to the type of commercial loan transaction evidenced by the Loan Documents. Nevertheless, in view of the plain language of the statutes, and the fact that the matter has not been considered by the Pennsylvania courts, we cannot say that the ultimate resolution of this issue is free from doubt.

The foregoing opinion is limited to the substantive laws of the State of Maryland and the Commonwealth of Pennsylvania (collectively, the “States”) and we do not express any opinion herein concerning any other law. We express no opinion as to the applicability or effect of federal or state securities laws, including the securities laws of the States, or as to federal or state laws regarding fraudulent transfers. We note that Section 12.12 of the Term Loan Agreement provides that the Term Loan Agreement shall be governed by the laws of the State of New York. To the extent that any matter as to which our opinion is expressed herein would be governed by the laws of any jurisdiction other than the States, we do not express any opinion on such matter. Our opinion expressed in paragraphs 6, 7, 8 and 9 above is based upon our consideration of only those laws, governmental regulations or rules of the States, which, in our experience, are normally applicable to the transactions of the type contemplated under the Term Loan Agreement. Our opinion expressed in paragraphs 10 and 11 above is based upon our consideration of only those consents, approvals, registrations, notices or other actions required by the States, if any, which, in our experience, are normally applicable to the transactions of the type contemplated under the Term Loan Agreement. The opinion expressed herein is subject to the effect of any judicial decision which may permit the introduction of parol evidence to modify the terms or the interpretation of agreements.

F-2-6

We assume no obligation to supplement this opinion if any applicable law changes after the date hereof or if we become aware of any fact that might change the opinion expressed herein after the date hereof.

This opinion is being furnished to you solely for your benefit in connection with the Term Loan Agreement. Accordingly, it may not be relied upon by, quoted in any manner to, or delivered (except delivery by the Lenders (a) to regulatory authorities, (b) in connection with any litigation involving any of the Loan Documents or this opinion or (c) as otherwise required by law) to any other person or entity without, in each instance, our prior written consent, except that a financial institution that is an Assignee (as defined in the Term Loan Agreement) of a Lender may rely on this opinion as if addressed to it on the date hereof.

Very truly yours,

FORM OF GUARANTY

THIS GUARANTY dated as of February 25, 2004, executed and delivered by each of the undersigned and the other Persons from time to time party hereto pursuant to the execution and delivery of an Accession Agreement in the form of Annex I hereto (all of the undersigned, together with such other Persons each a “Guarantor” and collectively, the “Guarantors”) in favor of (a) WACHOVIA BANK, NATIONAL ASSOCIATION, in its capacity as Agent (the “Agent”) for the Lenders under that certain that certain Term Loan Agreement dated as of February 25, 2004 (as amended, restated, supplemented or otherwise modified from time to time, the “Term Loan Agreement”), by and among HRPT Properties Trust (the “Borrower”), the financial institutions party thereto and their assignees under Section 12.5 thereof (the “Lenders”), the Agent, and the other parties thereto, and (b) the Lenders.

WHEREAS, pursuant to the Term Loan Agreement, the Agent and the Lenders have agreed to make available to the Borrower certain financial accommodations on the terms and conditions set forth in the Term Loan Agreement;

WHEREAS, the Borrower owns, directly or indirectly, at least a majority of the issued and outstanding Equity Interests in each Guarantor;

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

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

WHEREAS, each Guarantor’s execution and delivery of this Guaranty is a condition to the Agent and the Lenders making, and continuing to make, such financial accommodations to the Borrower.

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

Section 1. Guaranty. Each Guarantor hereby absolutely, irrevocably and unconditionally guaranties the due and punctual payment and performance when due, whether at stated maturity, by acceleration or otherwise, of all of the following (collectively referred to as the “Guarantied

H-1

Obligations”): (a) all indebtedness and obligations owing by the Borrower to any Lender or the Agent under or in connection with the Term Loan Agreement and any other Loan Document, including without limitation, the repayment of all principal of the Term Loans and the payment of all interest, Fees, charges, attorneys’ fees and other amounts payable to any Lender or the Agent thereunder or in connection therewith; (b) any and all extensions, renewals, modifications, amendments or substitutions of the foregoing; (c) all expenses, including, without limitation, reasonable attorneys’ fees and disbursements, that are incurred by the Lenders and the Agent in the enforcement of any of the foregoing or any obligation of such Guarantor hereunder; and (d) all other Obligations.

Section 2. Guaranty of Payment and Not of Collection. This Guaranty is a guaranty of payment, and not of collection, and a debt of each Guarantor for its own account. Accordingly, neither the Lenders nor the Agent shall be obligated or required before enforcing this Guaranty against any Guarantor: (a) to pursue any right or remedy any of them may have against the Borrower, any other Guarantor or any other Person or commence any suit or other proceeding against the Borrower, any other Guarantor or any other Person in any court or other tribunal; (b) to make any claim in a liquidation or bankruptcy of the Borrower, any other Guarantor or any other Person; or (c) to make demand of the Borrower, any other Guarantor or any other Person or to enforce or seek to enforce or realize upon any collateral security held by the Lenders or the Agent which may secure any of the Guarantied Obligations.

Section 3. Guaranty Absolute. Each Guarantor guarantees that the Guarantied Obligations will be paid strictly in accordance with the terms of the documents evidencing the same, regardless of any Applicable Law now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Agent or the Lenders with respect thereto. The liability of each Guarantor under this Guaranty shall be absolute, irrevocable and unconditional in accordance with its terms and shall remain in full force and effect without regard to, and shall not be released, suspended, discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever, including without limitation, the following (whether or not such Guarantor consents thereto or has notice thereof):

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

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

H-2

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

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

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

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

(g) any nonperfection or impairment of any security interest or other Lien on any collateral, if any, securing in any way any of the Obligations;

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

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

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

Section 4. Action with Respect to Guarantied Obligations. The Lenders and the Agent may, at any time and from time to time, without the consent of, or notice to, any Guarantor, and without discharging any Guarantor from its obligations hereunder, take any and all actions described in Section 3 and may otherwise: (a) amend, modify, alter or supplement the terms of any of the Guarantied Obligations, including, but not limited to, extending or shortening the time of payment of any of the Guarantied Obligations or changing the interest rate that may accrue on any of the Guarantied Obligations; (b) amend, modify, alter or supplement the Term Loan Agreement or any other Loan Document; (c) sell, exchange, release or otherwise deal with all, or any part, of any collateral securing any of the Obligations; (d) release any other Loan Party or other Person liable in any manner for the payment or collection of the Guarantied Obligations; (e) exercise, or refrain from exercising, any rights

H-3

against the Borrower, any other Guarantor or any other Person; and (f) apply any sum, by whomsoever paid or however realized, to the Guarantied Obligations in such order as the Lenders shall elect.

Section 5. Representations and Warranties. Each Guarantor hereby makes to the Agent and the Lenders all of the representations and warranties made by the Borrower with respect to or in any way relating to such Guarantor in the Term Loan Agreement and the other Loan Documents, as if the same were set forth herein in full.

Section 6. Covenants. Each Guarantor will comply with all covenants which the Borrower is to cause such Guarantor to comply with under the terms of the Term Loan Agreement or any of the other Loan Documents.

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

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

Section 9. Reinstatement of Guarantied Obligations. If claim is ever made on the Agent or any Lender for repayment or recovery of any amount or amounts received in payment or on account of any of the Guarantied Obligations, and the Agent or such Lender repays all or part of said amount by reason of (a) any judgment, decree or order of any court or administrative body of competent jurisdiction, or (b) any settlement or compromise of any such claim effected by the Agent or such Lender with any such claimant (including the Borrower or a trustee in bankruptcy for the Borrower), then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding on it, notwithstanding any revocation hereof or the cancellation of the Term Loan Agreement, any of the other Loan Documents, or any other instrument evidencing any liability of the Borrower, and such Guarantor shall be and remain liable to the Agent or such Lender for the amounts so repaid or recovered to the same extent as if such amount had never originally been paid to the Agent or such Lender.

Section 10. Subrogation. Upon the making by any Guarantor of any payment hereunder for the account of the Borrower, such Guarantor shall be subrogated to the rights of the payee against the Borrower; provided, however, that such Guarantor shall not enforce any right or receive any payment by way of subrogation or otherwise take any action in respect of any other claim or cause of action such Guarantor may have against the Borrower arising by reason of any payment or performance by such Guarantor pursuant to this Guaranty, unless and until all of the Guarantied Obligations have been

H-4

indefeasibly paid and performed in full. If any amount shall be paid to such Guarantor on account of or in respect of such subrogation rights or other claims or causes of action, such Guarantor shall hold such amount in trust for the benefit of the Agent and the Lenders and shall forthwith pay such amount to the Agent to be credited and applied against the Guarantied Obligations, whether matured or unmatured, in accordance with the terms of the Term Loan Agreement or to be held by the Agent as collateral security for any Guarantied Obligations existing.

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

Section 12. Set-off. In addition to any rights now or hereafter granted under any of the other Loan Documents or Applicable Law and not by way of limitation of any such rights, each Guarantor hereby authorizes the Agent and each Lender, at any time during the continuance of an Event of Default, without any prior notice to such Guarantor or to any other Person, any such notice being hereby expressly waived, but in the case of a Lender subject to receipt of the prior written consent of the Agent exercised in its sole discretion, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other indebtedness at any time held or owing by the Agent, such Lender, or any affiliate of the Agent or such Lender, to or for the credit or the account of such Guarantor against and on account of any of the Guarantied Obligations, although such obligations shall be contingent or unmatured. Each Guarantor agrees, to the fullest extent permitted by Applicable Law, that any Participant may exercise rights of setoff or counterclaim and other rights with respect to its participation as fully as if such Participant were a direct creditor of such Guarantor in the amount of such participation.

Section 13. Subordination. Each Guarantor hereby expressly covenants and agrees for the benefit of the Agent and the Lenders that all obligations and liabilities of the Borrower to such Guarantor of whatever description, including without limitation, all intercompany receivables of such Guarantor from the Borrower (collectively, the “Junior Claims”) shall be subordinate and junior in right of payment to all Guarantied Obligations. If an Event of Default shall have occurred and be continuing, then no Guarantor shall accept any direct or indirect payment (in cash, property or securities, by setoff or otherwise) from the Borrower on account of or in any manner in respect of any Junior Claim until all of the Guarantied Obligations have been indefeasibly paid in full.

Section 14. Avoidance Provisions. It is the intent of each Guarantor, the Agent and the Lenders that in any Proceeding, such Guarantor’s maximum obligation hereunder shall equal, but not exceed, the maximum amount which would not otherwise cause the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders) to be avoidable or

H-5

unenforceable against such Guarantor in such Proceeding as a result of Applicable Law, including without limitation, (a) Section 548 of the Bankruptcy Code of 1978, as amended (the “Bankruptcy Code”) and (b) any state fraudulent transfer or fraudulent conveyance act or statute applied in such Proceeding, whether by virtue of Section 544 of the Bankruptcy Code or otherwise. The Applicable Laws under which the possible avoidance or unenforceability of the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders) shall be determined in any such Proceeding are referred to as the “Avoidance Provisions”. Accordingly, to the extent that the obligations of any Guarantor hereunder would otherwise be subject to avoidance under the Avoidance Provisions, the maximum Guarantied Obligations for which such Guarantor shall be liable hereunder shall be reduced to that amount which, as of the time any of the Guarantied Obligations are deemed to have been incurred under the Avoidance Provisions, would not cause the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders), to be subject to avoidance under the Avoidance Provisions. This Section is intended solely to preserve the rights of the Agent and the Lenders hereunder to the maximum extent that would not cause the obligations of any Guarantor hereunder to be subject to avoidance under the Avoidance Provisions, and no Guarantor or any other Person shall have any right or claim under this Section as against the Agent and the Lenders that would not otherwise be available to such Person under the Avoidance Provisions.

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

Section 16. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED, AND TO BE FULLY PERFORMED, IN SUCH STATE.

SECTION 17. WAIVER OF JURY TRIAL.

(a) EACH PARTY HERETO ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY BETWEEN OR AMONG ANY GUARANTOR, THE AGENT OR ANY OF THE LENDERS WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE LENDERS, THE AGENT AND EACH GUARANTOR HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR BY REASON OF ANY OTHER SUIT, CAUSE OF ACTION OR DISPUTE

H-6

WHATSOEVER BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS OF ANY KIND OR NATURE.

(b) EACH OF THE GUARANTORS, THE AGENT AND EACH LENDER HEREBY AGREES THAT THE FEDERAL DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, ANY STATE COURT LOCATED IN NEW YORK, NEW YORK, SHALL HAVE NONEXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN OR AMONG ANY GUARANTOR, THE AGENT OR ANY OF THE LENDERS, PERTAINING DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE LOANS, THE NOTES OR ANY OTHER LOAN DOCUMENT OR TO ANY MATTER ARISING HEREFROM OR THEREFROM. EACH GUARANTOR AND EACH OF THE LENDERS EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS. EACH PARTY FURTHER WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM AND EACH AGREES NOT TO PLEAD OR CLAIM THE SAME. THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY THE AGENT OR ANY LENDER OR THE ENFORCEMENT BY THE AGENT OR ANY LENDER OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY OTHER APPROPRIATE JURISDICTION.

Section 18. Loan Accounts. The Agent and each Lender may maintain books and accounts setting forth the amounts of principal, interest and other sums paid and payable with respect to the Guarantied Obligations, and in the case of any dispute relating to any of the outstanding amount, payment or receipt of any of the Guarantied Obligations or otherwise, the entries in such books and accounts shall be deemed prima facie evidence of the amounts and other matters set forth herein. The failure of the Agent or any Lender to maintain such books and accounts shall not in any way relieve or discharge any Guarantor of any of its obligations hereunder.

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

H-7

Section 20. Termination. This Guaranty shall remain in full force and effect until indefeasible payment in full of the Guarantied Obligations and the other Obligations and the termination or cancellation of the Term Loan Agreement in accordance with its terms.

Section 21. Successors and Assigns. Each reference herein to the Agent or the Lenders shall be deemed to include such Person’s respective successors and assigns (including, but not limited to, any holder of the Guarantied Obligations) in whose favor the provisions of this Guaranty also shall inure, and each reference herein to each Guarantor shall be deemed to include such Guarantor’s successors and assigns, upon whom this Guaranty also shall be binding. The Lenders may, in accordance with the applicable provisions of the Term Loan Agreement, assign, transfer or sell any Guarantied Obligation, or grant or sell participations in any Guarantied Obligations, to any Person without the consent of, or notice to, any Guarantor and without releasing, discharging or modifying any Guarantor’s obligations hereunder. Each Guarantor hereby consents to the delivery by the Agent or any Lender to any Assignee or Participant (or any prospective Assignee or Participant) of any financial or other information regarding the Borrower or any Guarantor. No Guarantor may assign or transfer its obligations hereunder to any Person without the prior written consent of all Lenders and any such assignment or other transfer to which all of the Lenders have not so consented shall be null and void.

Section 22. JOINT AND SEVERAL OBLIGATIONS. THE OBLIGATIONS OF THE GUARANTORS HEREUNDER SHALL BE JOINT AND SEVERAL, AND ACCORDINGLY, EACH GUARANTOR CONFIRMS THAT IT IS LIABLE FOR THE FULL AMOUNT OF THE “GUARANTIED OBLIGATIONS” AND ALL OF THE OBLIGATIONS AND LIABILITIES OF EACH OF THE OTHER GUARANTORS HEREUNDER.

Section 23. Amendments. This Guaranty may not be amended except in writing signed by the Requisite Lenders (or all of the Lenders if required under the terms of the Term Loan Agreement), the Agent and each Guarantor.

Section 24. Payments. All payments to be made by any Guarantor pursuant to this Guaranty shall be made in Dollars, in immediately available funds to the Agent at the Principal Office, not later than 2:00 p.m. on the date of demand therefor.

Section 25. Notices. All notices, requests and other communications hereunder shall be in writing (including facsimile transmission or similar writing) and shall be given (a) to each Guarantor at its address set forth below its signature hereto, (b) to the Agent or any Lender at its respective address for notices provided for in the Term Loan Agreement, or (c) as to each such party at such other address as such party shall designate in a written notice to the other parties. Each such notice, request or other communication shall be effective (i) if mailed, when received; (ii) if telecopied, when transmitted; or (iii) if hand delivered, when delivered; provided, however, that any notice of a change of address for notices shall not be effective until received.

H-8

Section 26. Severability. In case any provision of this Guaranty shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 27. Headings. Section headings used in this Guaranty are for convenience only and shall not affect the construction of this Guaranty.

Section 28. Trustees, Etc. Not Liable.

IN THE CASE OF ANY GUARANTOR THAT IS A TRUST, NO TRUSTEE, OFFICER, SHAREHOLDER, EMPLOYEE OR AGENT OF SUCH GUARANTOR SHALL BE HELD TO ANY PERSONAL LIABILITY, JOINTLY OR SEVERALLY, FOR ANY OBLIGATION OF, OR CLAIM AGAINST, SUCH GUARANTOR. ALL PERSONS DEALING WITH SUCH GUARANTOR, IN ANY WAY, SHALL LOOK ONLY TO THE ASSETS OF SUCH GUARANTOR FOR THE PAYMENT OF ANY SUM OR THE PERFORMANCE OF ANY OBLIGATION OWING BY SUCH GUARANTOR HEREUNDER. THE PROVISIONS OF THIS SECTION SHALL NOT LIMIT ANY OBLIGATIONS OF ANY LOAN PARTY.

Section 29. Limitation of Liability.

Neither the Agent nor any Lender, nor any affiliate, officer, director, employee, attorney, or agent of the Agent or any Lender, shall have any liability with respect to, and each Guarantor hereby waives, releases, and agrees not to sue any of them upon, any claim for any special, indirect, incidental, or consequential damages suffered or incurred by a Guarantor in connection with, arising out of, or in any way related to, this Guaranty or any of the other Loan Documents, or any of the transactions contemplated by this Guaranty, the Term Loan Agreement or any of the other Loan Documents. Each Guarantor hereby waives, releases, and agrees not to sue the Agent or any Lender or any of the Agent’s or any Lender’s affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with, arising out of, or in any way related to, this Guaranty, the Term Loan Agreement or any of the other Loan Documents, or any of the transactions contemplated by Term Loan Agreement or financed thereby.

Section 30. Definitions. (a) For the purposes of this Guaranty:

“Proceeding” means any of the following: (i) a voluntary or involuntary case concerning any Guarantor shall be commenced under the Bankruptcy Code of 1978, as amended; (ii) a custodian (as defined in such Bankruptcy Code or any other applicable bankruptcy laws) is appointed for, or takes charge of, all or any substantial part of the property of any Guarantor; (iii) any other proceeding under any Applicable Law, domestic or foreign, relating to bankruptcy, insolvency, reorganization, winding-up or composition for adjustment of debts, whether now or hereafter in effect, is commenced relating to any Guarantor; (iv) any Guarantor is adjudicated insolvent or bankrupt; (v) any order of relief or other order approving any such case or proceeding is entered by a court of competent jurisdiction; (vi) any Guarantor makes a general assignment for the benefit of creditors; (vii) any Guarantor shall fail to pay,

H-9

or shall state that it is unable to pay, or shall be unable to pay, its debts generally as they become due; (viii) any Guarantor shall call a meeting of its creditors with a view to arranging a composition or adjustment of its debts; (ix) any Guarantor shall by any act or failure to act indicate its consent to, approval of or acquiescence in any of the foregoing; or (x) any corporate action shall be taken by any Guarantor for the purpose of effecting any of the foregoing.

(b) Terms not otherwise defined herein are used herein with the respective meanings given them in the Term Loan Agreement.
