(c) A certificate of the Bank setting forth a reasonably detailed calculation of the amount or amounts necessary to compensate the Bank or its holding company, as the case may be, as specified in sections 2.7(a) or 2.7(b) shall be delivered to the Borrower and shall be conclusive absent demonstrable error. The Borrower shall pay the Bank the amount shown as due on any such certificate (absent demonstrable error in such certificate) within 10 Business Days after receipt thereof by the Borrower.

more than 270 days prior to the date that the Borrower receives the applicable certificate pursuant to section 2.11(c); provided further that, if the Change in Law giving rise to such amount or amounts is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

8. Guaranty.

8.1 Guaranty. Each of the Loan Guarantors hereby agrees that it is jointly and severally liable for, and, as primary obligor and not merely as surety, absolutely and unconditionally guarantees to the Bank the prompt payment when due, whether at stated maturity, upon acceleration or otherwise, and at all times thereafter, of the Obligations (the “Guaranteed Obligations”). Each of the Loan Guarantors further agrees that the Guaranteed Obligations may be extended or renewed in whole or in part without notice to or further assent from it, and that it remains bound upon its guarantee notwithstanding any such extension or renewal. All terms of this apply to and may be enforced by or on behalf of any domestic or foreign branch or Affiliate of the Bank that extended any portion of the Guaranteed Obligations.

8.2 Guaranty of Payment. This Loan Guaranty is a guaranty of payment and not of collection. Each of the Loan Guarantors waives any right to require the Bank to ▇▇▇ the Borrower or any of the other Loan Guarantors, any other guarantor, or any other person obligated for all or any part of the Guaranteed Obligations (each, an “Obligated Party” and collectively, the “Obligated Parties”), or otherwise to enforce its payment against any collateral securing all or any part of the Guaranteed Obligations.

8.3 No Discharge or Diminishment of Loan Guaranty.

(a) Except as otherwise provided for herein, the obligations of each of the Loan Guarantors hereunder are unconditional and absolute and not subject to any reduction, limitation, impairment or termination for any reason (other than the payment in full in cash of the Guaranteed Obligations), including: (i) any claim of waiver, release, extension, renewal, settlement, surrender, alteration, or compromise of any of the Guaranteed Obligations, by operation of law or otherwise; (ii) any change in the corporate existence, structure or ownership of the Borrower, any other of the Loan Guarantors or any other guarantor of or other person liable for any of the Guaranteed Obligations; (iii) any insolvency, bankruptcy, winding up, liquidation, reorganization or other similar proceeding affecting any of the Obligated Parties, or such Obligated Party’s property or any resulting release or discharge of any obligation of any of the Obligated Parties; or (iv) the existence of any claim, setoff or other rights which any Loan Guarantor may have at any time against any Obligated Party, the Bank or any other person, whether in connection herewith or in any unrelated transactions.

(b) The obligations of each of the Loan Guarantors hereunder are not subject to any defense or setoff, counterclaim, recoupment, or termination whatsoever by reason of the invalidity, illegality, or unenforceability of any of the Guaranteed Obligations or otherwise, or any provision of applicable law or regulation purporting to prohibit payment by any of the Obligated Parties, of the Guaranteed Obligations or any part thereof.

(c) Further, the obligations of any of the Loan Guarantors hereunder are not discharged or impaired or otherwise affected by: (i) the failure of the Bank to assert any claim or demand or to enforce any remedy with respect to all or any part of the Guaranteed Obligations; (ii) any waiver or modification of or supplement to any provision of any agreement relating to the Guaranteed Obligations (other than any of the foregoing in which the Bank expressly modifies the obligations of any Loan Guarantor hereunder); (iii) any release, non-perfection, or invalidity of any indirect or direct security for the obligations of the Borrower or of all or any part of the Guaranteed Obligations or any obligations of any other guarantor of or other person liable for any of the Guaranteed Obligations; (iv) any action or failure to act by the Bank with respect to any collateral securing any part of the Guaranteed Obligations (other than actions or failures to act by the Bank or any of its Affiliates constituting gross negligence or willful misconduct); or (v) any default, failure or delay, willful or otherwise, in the payment or performance of any of the Guaranteed Obligations, or any other circumstance, act, omission or delay that might in any manner or to any extent vary the risk of such Loan Guarantor or that would otherwise operate as a discharge of any of the Loan Guarantors as a matter of law or equity (other than the payment in full in cash of the Guaranteed Obligations or actions or failures to act by the Bank or any of its Affiliates constituting gross negligence or willful misconduct).

8.4 Defenses Waived. To the fullest extent permitted by applicable law, each of the Loan Guarantors hereby waives any defense based on or arising out of any defense of the Borrower or any of the Loan Guarantors or the unenforceability of all or any part of the Guaranteed Obligations from any cause, or the cessation from any cause of the liability of the Borrower or any of the Loan Guarantors, other than the payment in full in cash of the Guaranteed Obligations or any defense arising from the gross negligence or willful misconduct of the Bank or any of its Affiliates. Without limiting the generality of the foregoing, each of the Loan Guarantors irrevocably waives acceptance hereof, presentment, demand, protest and, to the fullest extent permitted by law, any notice not provided for herein, as well as any requirement that at any time any action be taken by any person against any of the other Obligated Parties, or any other person. The Bank may, at its election, foreclose on any collateral securing the Obligations held by it by one or more judicial or nonjudicial sales, accept an assignment of any such collateral in lieu of foreclosure or otherwise act or fail to act with respect to any collateral securing all or a part of the Guaranteed Obligations, compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with any of the Obligated Parties or exercise any other right or remedy available to it against any of the Obligated Parties, without affecting or impairing in any way the liability of such Loan Guarantor under this Loan Guaranty except to the extent the Guaranteed Obligations have been fully paid in cash or to the extent the Bank or any of its Affiliates acts or fails to act in a manner constituting gross negligence or willful misconduct. To the fullest extent permitted by applicable law, each of the Loan Guarantors waives any defense arising out of any such election even though that election may operate, pursuant to applicable law, to impair or extinguish any right of reimbursement or subrogation or other right or remedy of any of the Loan Guarantors against any of the Obligated Parties or any security.

8.5 Rights of Subrogation. No Loan Guarantor will assert any right, claim or cause of action, including, without limitation, a claim of subrogation, contribution or indemnification that it has against any of the Obligated Parties, or any collateral, until the Loan Parties and the Loan Guarantors have fully performed all their obligations to the Bank hereunder, under the Loan Documents and under any agreement, document or instrument evidencing Related Rate Management Transactions.

8.6 Reinstatement; Stay of Acceleration. If at any time any payment of any portion of the Guaranteed Obligations is rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, or reorganization of the Borrower, each of the Loan Guarantors’ obligations under this Loan Guaranty with respect to that payment shall be reinstated at such time as though the payment had not been made and whether or not the Bank is in possession of this Loan Guaranty. If acceleration of the time for payment of any of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or reorganization of the Borrower, all such amounts otherwise subject to acceleration under the terms of any agreement relating to the Guaranteed Obligations shall nonetheless be payable by the Loan Guarantors forthwith on demand by the Bank.

8.7 Information. Each of the Loan Guarantors assumes all responsibility for being and keeping itself informed of the Borrower’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that each of the Loan Guarantors assumes and incurs under this Loan Guaranty, and agrees that the Bank shall not have any duty to advise any of the Loan Guarantors of information known to it regarding those circumstances or risks.

8.8 Termination. The Bank may continue to make loans or extend credit to the Borrower based on this Loan Guaranty until five days after it receives written notice of termination from any of the Loan Guarantors. Notwithstanding receipt of any such notice, each of the Loan Guarantors will continue to be liable to the Bank for any Guaranteed Obligations created, assumed or committed to prior to the fifth day after receipt of the notice, and all subsequent renewals, extensions, modifications and amendments with respect to, or substitutions for, all or any part of the Guaranteed Obligations. Any Loan Guarantor’s liability under this Agreement (including, without limitation, under this Loan Guaranty) shall automatically cease if such Loan Guarantor ceases to be a Subsidiary as the result of a transaction or series of related transactions that are not prohibited by this Agreement, and the Bank agrees to deliver to the Borrower such instruments of release or other documentation as the Borrower may reasonably request to evidence any such cessation of liability.

All payments of the Guaranteed Obligations will be made giving effect to the section 2.8.

8.9 Maximum Liability. The provisions of this Loan Guaranty are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any of the Loan Guarantors under this Loan Guaranty would otherwise be held or determined to be void, voidable, avoidable, invalid or unenforceable on account of the amount of such Loan Guarantor’s liability under this Loan Guaranty, then, notwithstanding any other provision of this Loan Guaranty to the contrary, the amount of such liability shall, without any further action by the Loan Guarantors or the Bank, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest amount determined

hereunder being the relevant Loan Guarantor’s “Maximum Liability”). This section with respect to the Maximum Liability of each of the Loan Guarantors is intended solely to preserve the rights of the Bank to the maximum extent not subject to avoidance under applicable law, and no Loan Guarantor nor any other person or entity shall have any right or claim under this section with respect to such Maximum Liability, except to the extent necessary so that the obligations of any of the Loan Guarantors hereunder shall not be rendered voidable under applicable law. Each of the Loan Guarantors agrees that the Guaranteed Obligations may at any time and from time to time exceed the Maximum Liability of each of the Loan Guarantors without impairing this Loan Guaranty or affecting the rights and remedies of the Bank hereunder; provided that, nothing in this sentence shall be construed to increase any of the Loan Guarantors’ obligations hereunder beyond its Maximum Liability.

8.10 Contribution. In the event any of the Loan Guarantors (a “Paying Guarantor”) shall make any payment or payments under this Loan Guaranty or shall suffer any loss as a result of any realization upon any collateral granted by it to secure its obligations under this Loan Guaranty, each of the other Loan Guarantors (each a “Non-Paying Guarantor”) shall contribute to such Paying Guarantor an amount equal to such Non-Paying Guarantor’s “Applicable Percentage” of such payment or payments made, or losses suffered, by such Paying Guarantor. For purposes of this section 8.10, each Non-Paying Guarantor’s “Applicable Percentage” with respect to any such payment or loss by a Paying Guarantor shall be determined as of the date on which such payment or loss was made by reference to the ratio of (a) such Non-Paying Guarantor’s Maximum Liability as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder) or, if such Non-Paying Guarantor’s Maximum Liability has not been determined, the aggregate amount of all monies received by such Non-Paying Guarantor from the Borrower after the date hereof (whether by loan, capital infusion or by other means) to (b) the aggregate Maximum Liability of all Loan Guarantors hereunder (including such Paying Guarantor) as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder), or to the extent that a Maximum Liability has not been determined for any Loan Guarantor, the aggregate amount of all monies received by such Loan Guarantors from the Borrower after the date hereof (whether by loan, capital infusion or by other means). Nothing in this provision shall affect any of the Loan Guarantors’ several liability for the entire amount of the Guaranteed Obligations (up to such Loan Guarantor’s Maximum Liability). Each of the Loan Guarantors covenants and agrees that its right to receive any contribution under this Loan Guaranty from a Non-Paying Guarantor shall be subordinate and junior in right of payment to the payment in full in cash of the Guaranteed Obligations. This provision is for the benefit of the Bank and the Loan Guarantors and may be enforced by any one, or more, or all of them in accordance with the terms hereof.

8.11 Liability Cumulative. The liability of each of the Loan Parties as one of the Loan Guarantors under this Article 8 is in addition to and shall be cumulative with all liabilities of each of the Loan Parties to the Bank under this Agreement and the other Loan Documents to which such Loan Party is a party or in respect of any obligations or liabilities of the other Loan Parties, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

9. Miscellaneous.

9.1 Survival of Representations and Warranties. The representations and warranties contained in section 3 hereof and in the other Loan Documents shall survive closing and execution and delivery of the Notes.

9.2 Indemnification. Except as incurred as a result of the Bank’s willful misconduct or gross negligence, each of the Loan Parties agrees to defend, indemnify and hold harmless the Bank, its directors, officers, employees and agents from and against any and all loss, cost, expense or liability (including reasonable attorneys’ fees) incurred in connection with any and all claims or proceedings (whether brought by a private party or Governmental Authority) as a result of, or arising out of or relating to:

(a) bodily injury, property damage, abatement or remediation, environmental damage or impairment or any other injury or damage resulting from or relating to any Hazardous Materials located on or migrating into, from or through property previously, now or hereafter owned or occupied by any of the Loan Parties, which the Bank may incur due to the making of the Loans, the exercise of any of its rights under the Collateral Documents, or otherwise;

(b) any transaction financed or to be financed, in whole or in part, directly or indirectly, with the proceeds of any Loan; or

This indemnity will survive foreclosure of any security interest or mortgage or conveyance in lieu of foreclosure and the repayment of the Notes and the discharge and release of any Collateral Documents.

Notwithstanding the foregoing, the foregoing indemnity shall not be available to the extent that such losses, costs, expenses or liabilities result from a claim brought by any of the Loan Parties against any indemnitee for breach of the Bank’s or its Affiliates’ respective obligations hereunder or under any other Loan Document, if the applicable Loan Party has obtained a final judgment in its favor on such claim as determined by a court or other tribunal of competent jurisdiction.

9.3 Expenses. Each of the Loan Parties agree, whether or not the transaction hereby contemplated shall be consummated, to pay on demand (accompanied by a reasonably detailed calculation of the amount demanded) (a) all out-of-pocket expenses incurred by the Bank in connection with the negotiation, execution, administration, amendment or enforcement of any Loan Document including the reasonable out-of-pocket fees and expenses of the Bank’s legal counsel, and (b) all out-of-pocket expenses, including the reasonable fees and expenses of the Bank’s legal counsel, incurred by the Bank in connection with any litigation, proceeding or dispute in any way related to this Agreement and the other Loan Documents. The Bank agrees to provide written notice to the Loan Parties Representative at any time it has incurred amounts for which it will seek reimbursement under this section 9.3 in an aggregate amount exceeding $25,000; provided that failure to provide such notice shall not affect the obligations of the Loan Parties under this section 9.3. The obligations of each of the Loan Parties under this section 9.3 will survive payment of the Notes.

9.4 Notices. Except as otherwise expressly provided in this Agreement, all notices provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by facsimile or e-mail transmission addressed as follows, or to such other address, facsimile number or e-mail address, as applicable, with respect to either party as such party shall notify the other in writing in accordance herewith; such notices shall be deemed given when received:

9.5 Setoff. As security for payment of the Obligations, each of the Loan Parties grants to the Bank a security interest in and lien on any credit balance or other money now or hereafter owed such Loan Party by the Bank. In addition, each of the Loan Parties agrees that the Bank may, at any time after the occurrence and during the continuance of an Event of Default, without prior notice, set off against any such credit balance or other money all or any part of the Obligations, irrespective of whether the Bank shall have made demand under this Agreement or any Loan Document and although such Obligations may be contingent or unmatured. The Bank agrees to provide prompt written notice of any such setoff to the Borrower, provided that any failure to give any such notice shall not invalidate the applicable setoff.

9.6 Participations. Each of the Loan Parties agree that the Bank may, at its option, sell to another financial institution or institutions participation interests in any Note and, in

connection with each such sale and thereafter, disclose to the purchaser or prospective purchaser of each such interest financial and other information concerning such Loan Party (subject to such purchaser or prospective purchaser agreeing to treat such information as confidential as set forth in section 9.16). In the event of a sale by the Bank of a participating interest to a purchaser, (a) the Bank’s obligations hereunder shall remain unchanged for all purposes and the Bank shall remain solely responsible for the performance of such obligations, (b) each of the Loan Parties shall continue to deal solely and directly with the Bank in connection with the Bank’s rights and obligations hereunder, (c) all amounts payable by any of the Loan Parties shall be paid directly to the Bank, (d) the Bank shall not transfer or grant any participating interest under which the purchaser has the right to approve any amendment to, or any consent or waive with respect to, this Agreement or any of the other Loan Documents, except to (i) extend the final maturity date of the Loans hereunder in which such purchaser is participating, (ii) reduce the interest rate applicable to the Loans hereunder in which such purchaser is participating, (iii) release all or substantially all of the collateral or guaranties (except to the extent expressly provided herein or in any of the Loan Documents) supporting the Loans hereunder in which such purchaser is participating, (iv) postpone the payment of, or reduce the amount of, the interest or fees payable to such purchaser through the Bank (other than a waiver of default interest) or (v) change the amount or due dates of scheduled principal repayments or prepayments or premiums and (e) all amounts payable by any of the Loan Parties hereunder shall (except as set forth below) be determined as if the Bank had not sold such participation. Each of the Loan Parties agree that if any portion of the Obligations are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each such purchaser shall be deemed to have, to the extent permitted by applicable law, the right of setoff in respect of its participating interest to the same extent as if the amount of its participating interest were owed directly to it. Each of the Loan Parties further agree that each such purchaser shall be entitled to the benefits of section 2.7(d) with respect to its participation in the Bank’s obligation to make Loans; provided that no such purchaser shall be entitled to receive any greater amount pursuant to that section than the Bank would have been entitled to receive if no such sale had occurred.

9.7 Titles. The titles of sections in this Agreement are for convenience only and do not limit or construe the meaning of any section.

9.8 Severability. In case any provision or obligation under any Loan Document shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

9.9 Parties Bound; Waiver. The provisions of this Agreement shall inure to the benefit of and be binding upon any successor of any of the parties hereto; provided that none of the rights of any of the Loan Parties under this Agreement are assignable, and provided, further, that the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (a) an Event of Default has occurred and is continuing at the time of such assignment, (b) such assignment is to an Affiliate of the Bank or (c) such assignment occurs with the sale of all or substantially all of the Bank’s assets.

The rights provided for in this Agreement and the other Loan Documents are cumulative and are not exclusive of any other rights, powers, privileges or remedies provided by law or in equity, or under any other instrument, documents or agreement now existing or hereafter arising.
