(j) (without limiting any other provision of this Agreement or any Related Document) there shall be any material loss or depreciation in the value of any of the Collateral for any reason, or Agent shall otherwise reasonably deem itself insecure with respect to the Collateral; or, unless expressly permitted by this Agreement or the Related Documents, all or any part of any of the Collateral or any direct, indirect, legal, equitable or beneficial interest therein is assigned, transferred or sold without Secured Party's prior written consent; or

8. DEFAULT REMEDIES.

(a) Notwithstanding any provision of any document or instrument evidencing or relating to any Liability: (i) upon the occurrence and during the continuance of any Event of Default specified in subsections (a)-(j) of the Section entitled "EVENTS OF DEFAULT," Secured Party at its option may declare the Liabilities immediately due and payable without notice or demand of any kind; and (ii) upon the occurrence of any Event of Default specified in subsections (k)-(m) of the Section entitled "EVENTS OF DEFAULT," the Liabilities shall be immediately and automatically due and payable without action of any kind on the part of Secured Party. Upon the occurrence and during the continuance of any Event of Default, Secured Party may exercise any rights and remedies under this Agreement, any related document or instrument (including any Related Document evidencing Liabilities or pertaining to Collateral), and at law or in equity.

(b) If any Event of Default shall have occurred and be continuing, then, in addition to having the right to exercise any rights and remedies of a secured party upon default under the Uniform Commercial Code in effect in Illinois and any State in which any Collateral is located, Agent may, in its sole discretion, exercise any rights or powers set forth in this Agreement. Secured Party may require Debtor to assemble the Collateral and deliver it to a place designated by Agent. Agent has no obligation to marshal Collateral or to clean up or otherwise prepare Collateral for sale, and may specifically disclaim any warranties as to the Collateral, including those of title, merchantability, and fitness for a particular purpose. Agent may comply with any applicable local, state or federal law requirements in connection with a disposition of Collateral, and compliance will not be considered adversely to affect the commercial reasonableness of any sale of Collateral. Debtor grants to Agent the right to enter into or on any premises where Collateral may be located for the purposes of exercising any remedies upon the occurrence of an Event of Default. Agent shall be deemed to have exercised reasonable care in the custody and preservation of Collateral if it takes such action for that purpose as Debtor requests in writing, but failure to do so shall not be deemed a failure to exercise ordinary care. No failure of Agent to preserve or protect any right with respect to Collateral against prior parties, or to do any act with respect to preservation of Collateral not so requested by Debtor, shall be deemed of itself

a failure to exercise reasonable care in the custody or preservation of Collateral. Without limiting any other provision hereof, Debtor shall pay all related expenses, including attorneys' fees and reasonable time charges of attorneys who may be employees of Agent. If any notification of intended disposition of any of the Collateral is required by law, such notification, if mailed, shall be deemed reasonably and properly given if mailed at least ten days before such disposition, postage prepaid, addressed to Debtor at the address of Debtor shown below. Agent shall, in addition to and not in limitation of all rights of offset under applicable law, have the right to appropriate and apply all of the Collateral in its possession to payment of the Liabilities. Agent may proceed to sell, lease or otherwise dispose of the Collateral at public or private sale for cash or credit, and may itself make a credit bid; provided, however, that Debtor shall be credited with proceeds thereof only when the proceeds are actually received in cash by Agent, and such shall be deemed commercially reasonable. Except as and if otherwise required by law, any proceeds of the Collateral sold or disposed of pursuant hereto shall be applied toward the Liabilities in such order as Agent shall determine in its sole discretion. Any balance remaining shall be returned to Debtor.

(c) Agent may, by written notice to Debtor, at any time and from time to time, waive any Event of Default or Unmatured Event of Default, which shall be for such period and subject to such conditions as shall be specified in any such notice. In the case of any such waiver, Agent and Debtor shall be restored to their former position and rights hereunder, and any Event of Default or Unmatured Event of Default so waived shall be deemed to be cured and not continuing; but no such waiver shall extend to or impair any subsequent or other Event of Default or Unmatured Event of Default. No failure to exercise, and no delay in exercising, on the part of Agent of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of Agent herein provided are cumulative and not exclusive of any rights or remedies provided by law.

(d) As to any Liabilities owed to any Lender, Agent shall act as collateral agent for such Lender and shall take or refrain from taking action, and shall distribute proceeds of Collateral and other amounts recovered hereunder or under any Related Document, between such Agent as they shall from time to time agree. Except as and if required by law Debtor shall have no obligation or right whatsoever to inquire into any agreements or arrangements between Agent and any Agent's acting as collateral agent for any Lender.

9. STANDARDS FOR EXERCISING REMEDIES. To the extent that the Uniform Commercial Code or other applicable law impose duties on Secured Party to exercise remedies in a commercially reasonable manner, Debtor acknowledges and agrees that it is not commercially unreasonable for Secured Party: (a) to fail to incur expenses reasonably deemed significant by Secured Party to prepare Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition; (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of; (c) to fail to exercise collection remedies against account debtors and other persons obligated on the Collateral or to remove liens or encumbrances on or any adverse claims against Collateral; (d) to exercise collection remedies against account debtors and other persons obligated on the Collateral directly or through the use of collection agencies and other collection specialists; (e) to advertise dispositions of Collateral through publications or media of general circulation; (f) to contact other persons, whether or not in the same business as Debtor, for expressions of interest in acquiring all or any portion of the Collateral; (g) to hire one or more professional auctioneers to assist in the disposition of Collateral; (h) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or to match buyers and sellers of assets; (i) to dispose of assets at wholesale, rather than in retail markets; (j) to disclaim all disposition warranties; (k) to purchase insurance or credit enhancements to insure Secured Party against risks of loss, collection or disposition of Collateral; or (l) to the extent deemed appropriate and desirable by Secured Party, to obtain the services of brokers, investment bankers, consultants and other professionals to assist Secured Party in the collection or disposition of Collateral. Debtor acknowledges and agrees that the purpose of this Section is to provide a non-exhaustive list of the conduct by Secured Party that would not be deemed commercially unreasonable in Secured Party's exercise of remedies in respect of the Collateral. Without limitation upon the foregoing, nothing in this Section shall be construed to grant any rights to Debtor or to impose any duties on Secured Party that would not be granted or imposed by applicable law in the absence of this Section.

10. RIGHTS OF SECURED PARTY. Without limiting any other rights Secured Party has under the law, Secured Party may, from time to time, at its option (but shall have no duty to):

(a) perform any agreement of Debtor hereunder that Debtor shall have failed to perform;

(b) take any other action which Agent deems necessary or desirable for the preservation of the Collateral or Agent 's interest therein and the carrying out of this Agreement, including: (i) any action to collect or realize upon the Collateral; (ii) the discharge of taxes, liens, security interests or other encumbrances at any time levied or placed on the Collateral; (iii) the discharge or keeping current of any obligation of Debtor having effect on the Collateral; (iv) receiving, endorsing and collecting all checks and other orders for the payment of money made payable to Debtor representing any dividend, interest payment or other distribution payable or distributable in respect of the Collateral or any part thereof, and to give full discharge for the same; and (v) causing any person or entity having possession of any Collateral to acknowledge that such person or entity holds such Collateral for the benefit of Secured Party; and

(c) sign, file, authenticate, and authorize the signing, filing and authentication of, such financing statements and other documents respecting any right of Agent in the Collateral, in any and all jurisdictions as Secured Party shall determine in its discretion.

Debtor hereby appoints Agent as Debtor's attorney in fact, which appointment is and shall be deemed to be irrevocable and coupled with an interest, for purposes of performing acts and signing and delivering any agreement, document, or instrument, on behalf of Debtor in accordance with this Section. Debtor will reimburse Agent for all reasonable expenses so incurred by Agent within 10 business days of receipt of a written request for reimbursement. Amounts unpaid by Debtor after such 10 business day period shall bear interest at a rate per year equal to two percent (2%) in addition to the Prime Rate until paid.

11. INSURANCE.

(a) Agent 's rights under this Section are in addition to any under other provisions of this Agreement.

(b) Unless Debtor provides Agent with evidence of any insurance coverage required by this Agreement or any Related Document, Agent may purchase insurance at Debtor's expense to protect Secured Party's interest in the Collateral. This insurance may, but need not, protect the Debtor's interests. The coverage that Agent may purchase may not pay any claim that Debtor makes or any claim that is made against Debtor in connection with the Collateral. Debtor may later cancel any insurance purchased by Agent, but only after providing Secured Party with evidence that Debtor has obtained insurance as required by this Agreement. If Agent purchases insurance for the Collateral, Debtor will be responsible for the costs of that insurance, including interest and any other charges Agent may impose in connection with the placement of the insurance, until the effective date of the cancellation or expiration of the insurance. The costs of the insurance may be added to Debtor's total outstanding balance or obligation. The costs of insurance may be more than the cost of insurance Debtor may be able to obtain on Debtor's own.

12. FURTHER ASSURANCES. Debtor agrees to do (or cause to be done) such further acts and things, and to execute and deliver (or cause to be executed and delivered) such additional conveyances, assignments, agreements, and instruments, as Agent may at any time request in connection with the administration or enforcement of this Agreement or related to the Collateral or any part thereof or in order better to assure and confirm unto Agent its rights, powers and remedies hereunder.

13. OBLIGATIONS UNCONDITIONAL; WAIVER OF DEFENSES. Debtor irrevocably agrees that no fact or circumstance whatsoever which might at law or in equity constitute a discharge or release of, or defense to the obligations of, a guarantor or surety shall limit or affect any obligations of Debtor under this Agreement or any document or instrument executed in connection herewith. Without limiting the generality of the foregoing:

(a) Agent may at any time and from time to time, without notice to Debtor, take any or all of the following actions without affecting or impairing the liability of Debtor on this Agreement:

(i) renew or extend time of payment of the Liabilities;

(ii) accept, substitute, release or surrender any security for the Liabilities; and

(iii) release any person primarily or secondarily liable on the Liabilities (including Borrower, any indorser, any Guarantor and any other Related Party).

(b) No delay in enforcing payment of the Liabilities, nor any amendment, waiver, change, or modification of any terms of any Related Document, shall release Debtor from any obligation hereunder. The obligations of Debtor under this Agreement are and shall be primary, continuing, unconditional and absolute (notwithstanding that at any time or from time to time all of the Liabilities may have been paid in full), irrespective of the value, genuineness, regularity, validity or enforceability of any Related Documents. In order to hold Debtor liable or exercise rights or remedies hereunder, there shall be no obligation on the part of Agent, at any time, to resort for payment to Borrower or any Related Party or to any other security for the Liabilities. Secured Party shall have the right to enforce this Agreement irrespective of whether or not other proceedings or steps are being taken against any other property securing the Liabilities or any other party primarily or secondarily liable on any of the Liabilities.

(c) Debtor irrevocably waives presentment, protest, notice of intent to accelerate, demand, notice of dishonor or default, notice of acceptance of this Agreement, notice of any loans made, extensions granted or other action taken in reliance hereon, and all other demands and notices of any kind in connection with this Agreement or the Liabilities.

(d) Until all Liabilities have been paid and fulfilled in full and no committed or uncommitted credit facility has been extended to Debtor or Borrower by Agent, Debtor waives any claim or other right which Debtor might now have or hereafter acquire against Borrower or any other person primarily or contingently liable on the Liabilities (including any Related Party) or that arises from the existence or performance of Debtor's obligations under this Agreement, including any right of subrogation, reimbursement, contribution, indemnification, or participation in any claim or remedy of Agent against Borrower or any other collateral security for the Liabilities, which Agent now has or hereafter acquires, however arising.

14. NOTICES. All notices, requests and demands to or upon the respective parties hereto shall be deemed to have been given or made five business days after a record has been deposited in the mail, postage prepaid, or one business day after a record has been deposited with a recognized overnight courier, charges prepaid or to be billed to the sender, or on the day of delivery if delivered manually with receipt acknowledged, in each case addressed or delivered if to Agent to its banking office indicated on the signature page to this Agreement (Attention: Banking) and if to Debtor to its address indicated on the signature page to this Agreement, or to such other address as may be hereafter designated in writing by the respective parties hereto by a notice in accord with this Section.

15. MISCELLANEOUS. This Agreement, the Related Documents, and any document or instrument executed in connection herewith or therewith, unless in each case otherwise specifically provided therein: (i) shall be governed by and construed in accordance with the internal law of the State of Illinois, except to the extent if any that the Uniform Commercial Code of the State of Illinois provides for the application of the law of a different State; and (ii) shall be deemed to have been executed in the State of Illinois. This Agreement shall bind Debtor, its(his)(her) heirs, trustees (including successor and replacement trustees), executors, personal representatives, successors and assigns, as well as all persons and entities who become bound as a debtor to this Agreement, and shall inure to the benefit of Agent, its successors and assigns, except that neither Debtor nor any person or entity who or which becomes bound as a debtor may transfer or assign any rights or obligations hereunder without the prior written consent of Agent. Debtor agrees to pay upon written demand all reasonable expenses (including attorneys' fees, legal costs and expenses, and time charges of attorneys who may be employees of Secured Party, in each case whether in or out of court, in original or appellate proceedings or in bankruptcy) incurred or paid by Agent or any holder hereof in connection with the enforcement or preservation of its rights hereunder, under any Related Document, or under any document or instrument executed in connection herewith or therewith. If there shall be more than one person or entity constituting Debtor, each of them shall be primarily, jointly and severally liable for all obligations hereunder. This Agreement may be executed in two or more counterparts, and (if there is more than one party) by each party on separate counterparts, each of which shall be deemed an original but which together shall constitute one and the same instrument.

SECURED PARTY IS LOCATED. DEBTOR AND (BY ITS ACCEPTANCE HEREOF AS PROVIDED BELOW) SECURED PARTY HEREBY CONSENT AND SUBMIT TO THE JURISDICTION OF ANY LOCAL, STATE OR FEDERAL COURT LOCATED IN OR HAVING JURISDICTION OVER SUCH COUNTY AND STATE, AND HEREBY IRREVOCABLY WAIVE ANY RIGHT THEY OR ANY OF THEM MAY HAVE TO REQUEST OR DEMAND TRIAL BY JURY, TO TRANSFER OR CHANGE THE VENUE OF ANY SUIT, ACTION OR OTHER PROCEEDING BROUGHT IN ACCORDANCE WITH THIS SECTION, OR TO CLAIM THAT ANY SUCH PROCEEDING HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. NO PARTY HERETO MAY SEEK OR RECOVER PUNITIVE OR CONSEQUENTIAL DAMAGES IN ANY PROCEEDING BROUGHT UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY RELATED DOCUMENT.

17. Termination. This Agreement and the assignments, pledges and security interests created or granted by this Agreement shall create a continuing security interest in the Collateral and shall terminate upon Borrower's satisfaction and compliance with the Leverage/Fixed Charge Requirement (as provided and defined in the Credit Agreement). Upon written notice from Borrower following such satisfaction and compliance, the Secured Party shall reassign and deliver to the Debtor all Collateral and documents then in custody or possession, and if requested by the Debtor, shall, at the cost and expense of the Debtor, execute and deliver to the Debtor for recording or filing in each office in which any assignment or financing statement relative to the Debtor or the agreement relating thereto or any part of the Collateral, shall have been filed or recorded, a termination statement or release under applicable law (including, if relevant, the UCC) releasing the Secured Party's interest therein, and such other documents and instruments as the Debtor may reasonably request all without recourse to or warranty whatsoever by the Secured Party and at the cost and expense of the Debtor.

(b) Nothing herein shall render the Lender liable under any existing or future Leases, regardless of the collection of rents thereunder, for any of the covenants or agreements of the Mortgagor under such Leases.

Section 1.5 Transfer Prohibited. If the Mortgaged Property, or any part thereof, is sold, transferred, conveyed, leased, assigned or encumbered in any manner, voluntarily or involuntarily without the Agent's prior written consent, then such sale, transfer, conveyance, assigned, or encumbrance shall constitute a default under this Mortgage and the Agent, at its option, may declare the indebtedness secured hereby plus accrued interest due and payable. If any of the membership interests of Mortgagor shall be sold, conveyed, transferred, assigned or exchanged after the execution and delivery of this Mortgage (other than to the Borrower), such transfer shall constitute a transfer or conveyance of the Property which is hereby prohibited.

The Agent will have the right to examine, copy and audit the Mortgagor's records and books of account at all reasonable times in a manner otherwise consistent with the Credit Agreement. The Mortgagor will deliver to the Agent at such times and in such form and containing such information as shall be required by the Agent, financial statements, including, without limitation, balance sheets, profit-and-loss statements, income and expense statements and all schedules and exhibits thereto as are customarily required by sound accounting practice in a manner otherwise consistent with the Credit Agreement. Such statements and information shall be prepared in accordance with generally accepted accounting principles by the Mortgagor or, at the Agent's option, by an independent certified public accountant approved by the Agent in advance of delivery of such statements and information.

Section 1.8 Performance by the Agent.

If the Mortgagor fails to perform any covenant, condition, term or agreement contained in this Mortgage, or if any action or proceeding of any kind (including but not limited to any bankruptcy, insolvency, arrangement, reorganization or other debtor-relief proceeding) is commenced which might affect the Agent's interest in the Mortgaged Property or the Agent's right to enforce its security, then the Agent may, at its option, take any actions and disburse any sums as may be necessary or desirable to protect or enforce this Mortgage or to remedy the failure of the Mortgagor to perform its covenants (without, however, waiving any default of the Mortgagor).

The Agent shall be entitled to all compensation, awards and other payments or relief thereof and is hereby authorized, at its option, to commence, appear in and prosecute in its own or the Mortgagor's name any action or proceeding relating to any condemnation. All such compensation, awards, damages, claims, rights of action and proceeds and the right thereto are hereby assigned by the Mortgagor to the Agent, which, after deducting therefrom all its expenses, including attorney's fees, may release any moneys so received by it without affecting the lien of this Mortgage or may apply the same in such manner as the Agent shall determine to the payment of the indebtedness secured hereby, and any balance of such moneys then remaining shall be paid to the Mortgagor.

(c) If the Mortgaged Property or any part thereof is damaged by fire or any other cause, the Mortgagor will give immediate written notice of the same to the Agent.

(d) If all or any part of the Mortgaged Property shall be damaged by fire or other casualty, the Mortgagor will promptly restore the Mortgaged Property to the equivalent of its original condition, regardless of whether insurance proceeds exist, are made available or are sufficient. If any part of the Mortgaged Property shall be physically damaged through condemnation, the Mortgagor will promptly restore, repair or alter the remaining property in a manner satisfactory to the Agent.

Section 1.17 Estoppel Affidavits. Within ten (10) days after written request from the Agent, the Mortgagor shall furnish a written statement, duly acknowledged, setting forth the unpaid rent and other amounts due on the Lease and stating whether or not any offsets or defenses exist against such rent or amounts, specifying the nature of the same.

(c) The Agent shall have the right, without prior notice, to conduct an inspection of the Mortgaged Property for Hazardous Substances, including, without limitation, asbestos, at any time during the term of the Loan and in sufficient detail to permit the Agent to determine whether Hazardous Substances are present, in use or have been disposed of on the Mortgaged Property. The Mortgagor will pay or reimburse the Agent for all reasonable expenses incurred in connection with any environmental inspection of the Mortgaged Property and any such expenses will be additional indebtedness of the Mortgagor to the Agent secured by this Mortgage and will be payable on demand; provided, however, that Mortgagor's obligation to reimburse shall only be applicable as to one (1) inspection annually. The Agent is hereby empowered to enter and to authorize others to enter upon the Land or Improvements for the purpose of performing an environmental inspection, without thereby becoming liable to the Mortgagor or any party in possession holding under the Mortgagor.

Section 1.19 Compliance with Lease.

Section 2.8 Receiver.

(a) If an Event of Default shall have occurred, the Agent, upon application to a court of competent jurisdiction, shall be entitled, without notice and without regard to the adequacy of any security for the indebtedness hereby secured or the solvency of any party bound for its payment, to the appointment of a receiver to take possession of and to operate the Mortgaged Property and to collect the Rents.

(g) Debtor or any Related Party shall dissolve, liquidate, merge, consolidate, or cease to be in existence for any reason, or there shall be any change in any Constituent Document of Debtor from that in force on the date hereof which may have a material adverse impact on the ability of Debtor to repay the Liabilities; or

(h) any person or entity presently not in control of a Debtor or Related Party which is not a natural person shall obtain control directly or indirectly of such a Debtor or Related Party, whether by purchase or gift of stock or assets, by contract, or otherwise; or

(i) Debtor shall grant or any person (other than Secured Party) shall obtain a security interest in any of the Collateral, or shall file any financing statement purportedly covering any Collateral; Debtor or any other person shall perfect (or attempt to perfect) such a security interest; a court shall determine that Secured Party does not have a first-priority security interest in any of the Collateral or in any other assets constituting security for the Liabilities, enforceable in accord with this Agreement (as to the Collateral) or the related collateral documents (as to such other assets); or any notice of a federal tax lien against Debtor or any Related Party shall be filed with any public recorder; or

(j) (without limiting any other provision of this Agreement or any Related Document) there shall be any material loss or depreciation in the value of any of the Collateral for any reason, or Secured Party shall otherwise reasonably deem itself insecure with respect to the Collateral; or, unless expressly permitted by this Agreement or the Related Documents, all or any part of any of the Collateral or any direct, indirect, legal, equitable or beneficial interest therein is assigned, transferred or sold without Secured Party's prior written consent;

9. DEFAULT REMEDIES.

occurrence and during the continuance of any Event of Default, Secured Party may exercise any rights and remedies under this Agreement, any Related Document or other document or instrument (including any Related Document evidencing Liabilities or pertaining to Collateral), and at law or in equity.

(i) without being required to give any prior notice to Debtor apply the cash (if any) then held by it hereunder toward the Liabilities in such order as Secured Party shall determine in its sole discretion; and

(ii) if there shall be no such cash or the cash so applied shall be insufficient to pay all obligations in full, sell the Collateral, or any part thereof, at any public or private sale, for cash, upon credit or for future delivery, as Secured Party shall deem appropriate, provided, however, that Debtor shall be credited with proceeds thereof only when the proceeds are actually received in cash by Secured Party, and such sale shall be deemed commercially reasonable. Secured Party shall be authorized at any such sale (to the extent it deems it advisable to do so, in its sole discretion) to restrict the prospective bidders or purchasers to persons who will represent and agree that they are purchasing the Collateral then being sold for their own account for investment and not with a view to the distribution or resale thereof, and upon consummation of any such sale Secured Party shall have the right to assign, transfer and deliver to the purchasers thereof the Collateral so sold. Each such purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of Debtor. Debtor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. Secured Party has no obligation to marshal Collateral or to clean up or otherwise prepare Collateral for sale, and may specifically disclaim any warranties as to the Collateral, including those of title, merchantability, and fitness for a particular purpose. Secured Party may comply with any applicable local, state or federal law requirements in connection with a disposition of Collateral, and compliance will not be considered adversely to affect the commercial reasonableness of any sale of Collateral. Debtor grants to Secured Party the right to enter into or on any premises where Collateral may be located for the purposes of exercising any remedies upon the occurrence of an Event of Default. Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of Collateral if it takes such action for that purpose as Debtor requests in writing, but failure to do so shall not be deemed a failure to exercise ordinary care; no failure of Secured Party to preserve or protect any right with respect to Collateral against prior parties, or to do any act with respect to preservation of Collateral not so requested by Debtor, shall be deemed of itself a failure to exercise reasonable care in the custody or preservation of Collateral. To the extent that notice of sale shall be required to be given by law, Secured Party shall give Debtor at least ten days' written notice of any such public sale or the date after which any such private sale or sales will be held. Secured Party shall not be obligated to make any sale of Collateral if it shall determine not to do so, regardless of the fact that notice of sale of Collateral may have been given. Secured Party may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by Secured Party until the sale price is paid by the purchaser thereof, but Secured Party shall not incur any liability in case any such purchaser shall fail to take up and pay for the Collateral so sold; in the case of any such failure, such Collateral may be sold again upon like notice. As an alternative to exercising the power of sale herein conferred upon it, Secured Party may proceed by a suit at law or in equity to foreclose this Agreement and to sell the Collateral, or any portion thereof, pursuant to a judgment or decree of a court of competent jurisdiction. Except as and if otherwise required by law, any proceeds of the Collateral sold or disposed of pursuant hereto shall be applied toward the Liabilities in such order as Secured Party shall determine in its sole discretion. Any balance remaining shall be returned to Debtor.

(c) Secured Party may, by written notice to Debtor, at any time and from time to time, waive any Event of Default or Unmatured Event of Default, which shall be for such period and subject to such conditions as shall be specified in any such notice. In the case of any such waiver, Secured Party and Debtor shall be restored to their former position and rights hereunder, and any Event of Default or Unmatured Event of Default so waived shall be deemed to be cured and not continuing; but no such waiver shall extend to or impair any subsequent or other Event of Default or Unmatured Event of Default. No failure to exercise, and no delay in exercising, on the part of Secured Party of any right, power or privilege hereunder shall preclude any other or further exercise thereof or

the exercise of any other right, power or privilege. The rights and remedies of Secured Party herein provided are cumulative and not exclusive of any rights or remedies provided by law.

(d) As to any Liabilities owed to any Lender, Secured Party shall act as collateral agent for such Lender and shall take or refrain from taking action, and shall distribute proceeds of Collateral and other amounts recovered hereunder or under any Related Document, between such Lender and Secured Party as they shall from time to time agree. Except as and if required by law Debtor shall have no obligation or right whatsoever to inquire into any agreements or arrangements between Secured Party and any Lender as to Secured Party's acting as collateral agent for any Lender.

10. RIGHTS OF SECURED PARTY. Without limiting any other rights Secured Party has under the law, Secured Party may, from time to time, at its option (but shall have no duty to):

(a) perform any agreement of Debtor hereunder that Debtor shall have failed to perform;

(b) take any other action which Secured Party deems necessary or desirable for the preservation of the Collateral or Secured Party's interest therein and the carrying out of this Agreement, including: (i) any action to collect or realize upon the Collateral; (ii) the discharge of taxes, liens, security interests or other encumbrances at any time levied or placed on the Collateral; (iii) the discharge or keeping current of any obligation of Debtor having effect on the Collateral; (iv) receiving, endorsing and collecting all checks and other orders for the payment of money made payable to Debtor representing any dividend, interest payment or other distribution payable or distributable in respect of the Collateral or any part thereof, and giving full discharge for the same; and (v) causing any person or entity having possession of any Collateral to acknowledge that such person or entity holds such Collateral for the benefit of Secured Party; and

(c) sign, file, authenticate, and authorize the signing, filing and authentication of, such financing statements and other documents respecting any right of Secured Party in the Collateral, in any and all jurisdictions as Secured Party shall determine in its discretion.

Debtor hereby appoints Secured Party as Debtor's attorney in fact, which appointment is and shall be deemed to be irrevocable and coupled with an interest, for purposes of performing acts and signing and delivering any agreement, document, or instrument, on behalf of Debtor in accordance with this Section. Debtor will reimburse Secured Party for all reasonable expenses so incurred by Secured Party within 10 business days of receipt of a written request for reimbursement. Amounts unpaid by Debtor after such 10 business day period shall bear interest thereon at a rate per year equal to two percent (2%) in addition to the Prime Rate until paid.

11. WAIVER OF DEFENSES. Debtor irrevocably waives presentment, protest, notice of intent to accelerate, demand, notice of dishonor or default, notice of acceptance of this Agreement, notice of any loans made, extensions granted or other action taken in reliance hereon, and all other demands and notices of any kind in connection with this Agreement or the Liabilities.

12. SECURED PARTY MAY ALSO BE INTERMEDIARY OR TRUSTEE. Debtor hereby irrevocably waives, releases and forever relinquishes any claim or right of any nature whatsoever based upon the fact that Intermediary or a trustee of any Debtor or Guarantor which is a trust is or may be Secured Party itself or a Secured Party Affiliate, and hereby irrevocably consents to any such circumstance. The rights and powers of Secured Party shall not in any way be restricted by reason of any such present or future circumstance.

13. FURTHER ASSURANCES. Debtor agrees to do (or cause to be done) such further acts and things, and to execute and deliver (or cause to be executed and delivered) such additional conveyances, assignments, agreements, and instruments, as Secured Party may at any time request in connection with the administration or enforcement of this Agreement or related to the Collateral or any part thereof or in order better to assure and confirm unto Secured Party its rights, powers and remedies hereunder.

14. INVESTMENT DECISIONS. Debtor agrees that, except for a duty of good faith, Secured Party shall have no duty to Debtor with regard to decisions which Secured Party may make with regard to purchasing, holding or selling Collateral while the same shall be under Secured Party's control.

15. NOTICES. All notices, requests and demands to or upon the respective parties hereto shall be deemed to have been given or made five business days after a record has been deposited in the mail, postage prepaid, or one business day after a record has been deposited with a recognized overnight courier, charges prepaid or to be billed to the sender, or on the day of delivery if delivered manually with receipt acknowledged, in each case addressed or delivered if to Secured Party to its banking office indicated above (Attention: Banking) and if to

Debtor to its address set forth above, or to such other address as may be hereafter designated in writing by the respective parties hereto by a notice in accord with this Section.

16. MISCELLANEOUS. This Agreement, the Related Documents, and any document or instrument executed in connection herewith or therewith, unless in each case otherwise specifically provided therein: (i) shall be governed by and construed in accordance with the internal law of the State of Illinois, except to the extent if any that the Uniform Commercial Code of the State of Illinois provides for the application of the law of a different State; and (ii) shall be deemed to have been executed in the State of Illinois. This Agreement shall bind Debtor, its(his)(her) heirs, trustees (including successor and replacement trustees), executors, personal representatives, successors and assigns, as well as all persons and entities who become bound as a debtor to this Agreement, and shall inure to the benefit of Secured Party, its successors and assigns, except that neither Debtor nor any person or entity who or which becomes bound as a debtor hereto may transfer or assign any rights or obligations hereunder without the prior written consent of Secured Party. Debtor agrees to pay upon written demand all reasonable expenses (including attorneys' fees, legal costs and expenses, and time charges of attorneys who may be employees of Secured Party, in each case whether in or out of court, in original or appellate proceedings or in bankruptcy) incurred or paid by Secured Party or any holder hereof in connection with the enforcement or preservation of its rights hereunder, under any Related Document, or under any document or instrument executed in connection herewith or therewith. If there shall be more than one person or entity constituting Debtor, each of them shall be primarily, jointly and severally liable for all obligations hereunder. This Agreement may be executed in two or more counterparts, and (if there is more than one party) by each party on separate counterparts, each of which shall be deemed an original but which together shall constitute one and the same instrument.

17. WAIVER OF JURY TRIAL, ETC.
