As security for the prompt and complete payment and performance when due (whether at stated maturity, by acceleration or otherwise) of all obligations, Pledgor hereby pledges, hypothecates, assigns, transfers, sets over and grants to Pledgee a first lien on and first security interest in, and a right of setoff with respect to: (a) the Pledged Collateral and all cash, securities, interest, dividends, distributions, rights and other property at any time and from time to time declared or distributed in respect of, in exchange for or attached to or issued with respect to any or all of the Pledged Collateral; (b) all other property delivered in substitution for or in addition to any of the foregoing, all certificates and instruments representing or evidencing such other property and all cash, securities, interest, dividends, distributions, rights and such other property at any time and from time to time declared or distributed in respect of, in exchange for or attached to or issued with respect to any or all of such other property; and (c) proceeds of any of the foregoing (including, without limitation, any insurance proceeds or payments under the Securities Investor Protection Act of 1970). 4.2. Pledgor shall concurrently with the execution and delivery of this Agreement, deliver to Pledgee all of the now existing Pledged Collateral, in suitable form for transfer by delivery and accompanied by duly executed instruments of transfer, instructions or assignments in blank (with any signatures appropriately guaranteed), all in form and substance acceptable to Pledgee. Whether or not a Default or Event of Default shall have occurred or be continuing, Pledgee shall be permitted to transfer all or any part of such Pledged Collateral into the name of Pledgee or its nominee, with or without disclosing that such Pledged Collateral is subject to the Lien under this Agreement. 4.3. Pledgor immediately shall deliver or cause to be delivered to Pledgee to hold as part of the Pledged Collateral, for the benefit of Pledgor, and, if received by Pledgor, shall be received in trust for the benefit of Pledgee and immediately delivered to Pledgee as so received: (a) after the occurrence of a Default or an Event of Default, cash, interest and dividends at any time or from time to time declared in respect of the Pledged Collateral; 17 EXHIBIT A (b) cash, securities, interest., dividends, distributions, rights and other property at any time and from time to time declared or distributed in respect of, or in exchange for or attached to or issued with respect to any or all of the Pledged Collateral, in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital, capital surplus or paid-in surplus; (c) all other property delivered in substitution for or in addition to any of the foregoing, all certificates and instruments representing or evidencing such other property and all cash, securities, interest, dividends, distributions, rights and such other property at any time and from time to time declared or distributed in respect of, in exchange for or attached to or issued with respect to any or all of such other property; and (d) cash paid, payable or otherwise distributed in respect of interest on, principal of, or in redemption of, or in exchange for, any Pledged Collateral. All such Pledged Collateral shall be in suitable form for transfer by delivery and accompanied by duly executed instruments of transfer, instructions, or assignments in blank (with any signatures appropriately guaranteed), all in form and substance acceptable to Pledgee. 4.4. Any cash delivered to Pledgee pursuant to SECTION 2(c) or SECTION 8 of this Agreement shall be held by Pledgee as cash collateral security for the prompt and complete payment and performance when due (whether at stated maturity, by acceleration or otherwise) of all obligations. Pledgee may after an Event of Default shall have occurred and be continuing apply any or all of such cash or cash collateral to the payment of any or all of the obligations. Pending such application, Pledgee may (but shall not be obligated to) invest the same in a savings account, under which deposits are available for immediate withdrawal, with such bank as Pledgee may, in its sole discretion, select. Interest payable on any such savings account described in the foregoing sentence shall be collected by Pledgee and shall be deposited and held as additional cash collateral in such savings account. 4.5. Pledgor covenants and agrees that it will not sell, assign or otherwise dispose of the Pledged Collateral, nor will it create or permit to exist any Lien on the Pledged Collateral, except in favor of Pledgee. Pledgor further covenants and agrees that it will defend Pledgee's right, title and security interest in and to the Pledged Collateral and the proceeds of the Pledged Collateral against claims and demands of all persons whatsoever. 5. VOTING RIGHTS. So long as no Default or Event of Default shall have occurred and be continuing, Pledgor shall be entitled to vote or consent with respect to the Pledged Collateral in any manner not inconsistent with this Agreement or the Credit Agreement. Pledgor grants to Pledgee an irrevocable proxy to vote the Pledged Collateral, which proxy shall be effective immediately upon the occurrence of a Default and shall be deemed coupled with an interest. Pledgor will not vote the Pledged Collateral to authorize the issuance of additional shares of capital stock of Katy (except pursuant to a stockholder vote required for issuance of shares to management) or to reclassify or change, directly or indirectly, any rights with respect to the Pledged Collateral. 6. FURTHER ASSURANCES. Pledgor agrees that at any time and from time to time, at the sole cost and expense of Pledgor, Pledgor will promptly execute and deliver all further instruments and documents, and take all further action (including, without limitation, the filing of Uniform Commercial Code financing statements), that may be necessary or desirable, or that Pledgee may request, in order to perfect and protect any security interest granted by Pledgor to Pledgee under 18 EXHIBIT A this Agreement or to enable Pledgee to exercise and enforce its rights and remedies with respect to any Pledged Collateral under this Agreement. 7. PLEDGEE APPOINTED ATTORNEY-IN-FACT. Pledgor appoints Pledgee and any officer or agent of Pledgee as Pledgor's attorney-in-fact, with full power of substitution and full authority in the place and stead of Pledgor and in the name of Pledgor or otherwise, from time to time in such person's discretion to take any action and to execute any instrument which such person may deem necessary or advisable to accomplish the purposes of this Agreement. Without limiting the generality of the foregoing, Pledgee shall have the right, whether or not a Default or Event of Default shall have occurred and be continuing, to (a) notify the parties obligated on any of the Pledged Collateral to make payment to Pledgee of any amounts due or to become due thereunder, and (b) take control of any of the Pledged Collateral not in Pledgee's possession. 8. REASONABLE CARE. 8.1. Pledgee shall be deemed to have exercised reasonable care in the custody and preservation of the Pledged Collateral in its possession if the Pledged Collateral is accorded treatment substantially equal to that which Pledgee accords securities held for its own account, it being understood that Pledgee shall not have any responsibility under any circumstances whatsoever for taking any necessary steps to preserve rights of Pledgor or any other person against any parties with respect to any Pledged Collateral. Pledgee shall further be deemed to have exercised reasonable care in the custody and preservation of any of the Pledged Collateral in its possession if it takes such action for that purpose as Pledgor shall request in writing, but failure by Pledgee to comply with any such request shall not of itself be deemed a failure to exercise reasonable care, and no failure by Pledgee to do any act with respect to the preservation of such Pledged Collateral not so requested by Pledgor, shall of itself be deemed a failure to exercise reasonable care in the custody or preservation of such Pledged Collateral. 8.2. Pledgor represents to Pledgee that Pledgor has made its own arrangements for keeping informed of changes or potential changes affecting the Pledged Collateral (including, but not limited to, rights to convert, rights to subscribe, payment of dividends, reorganization or other exchanges, tender offers and voting rights), and Pledgor agrees that Pledgee shall have no responsibility or liability for informing Pledgor of any such changes or potential changes or for taking any action or omitting to take any action with respect to such matters. 19 EXHIBIT A 9. INDEMNIFICATION. 9.1. Pledgor agrees to indemnify and hold harmless Pledgee, its directors, officers, counsel and employees and each Person, if any, who controls Pledgee within the meaning of the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended (any and all of whom are referred to in this SECTION 7 as the "INDEMNIFIED PARTIES" and individually as an "INDEMNIFIED PARTY"), from and against any and all losses, claims, damages and liabilities, joint or several (including all legal or other expenses reasonably incurred by any of the Indemnified Parties in connection with the preparation for or defense of any pending or threatened claim, action or proceeding, whether or not resulting in any liability) to which such Indemnified Party may become subject under any applicable Federal or state law or otherwise, caused by or arising out of, or allegedly caused by or arising out of, the preparation, review, negotiation, execution, delivery or performance of this Agreement, or any transaction contemplated hereby or thereby, other than losses, claims, damages or liabilities arising from the gross negligence or willful misconduct of the Indemnified Party. Promptly after receipt by an Indemnified Party of notice of any claim, action or proceeding with respect to which an Indemnified Party is entitled to indemnity hereunder, such Indemnified Party will notify Pledgor of such claim or the commencement of such action or proceeding; provided, however, that the failure of an Indemnified. Party to give notice as provided herein shall not relieve Pledgor of its obligations under this SECTION 7 with respect to such Indemnified Party, except to the extent that Pledgor actually is prejudiced by such failure. Pledgor will assume the defense of such claim, action or proceeding and will employ counsel satisfactory to the Indemnified Party and will pay the fees and expenses of such counsel. Notwithstanding the preceding sentence, the Indemnified Party will be entitled, at the expense of Pledgor, to employ counsel separate from counsel for Pledgor and for any other party in such action if the Indemnified Party determines in its sole discretion that a conflict of interest exists which makes representation by counsel chosen by Pledgor not advisable. In the event that an Indemnified Party is subpoenaed to testify or produce documents in any action or proceeding brought against Pledgor (or any of its officers, directors or employees) in which such Indemnified Party is not named as a defendant (and is not itself a plaintiff) or in which Pledgor consents to such testimony or production, Pledgor agrees to reimburse such Indemnified Party for all expenses incurred by it (including fees and expenses of counsel) in connection with its appearing as a witness or producing documents. 9.2. SURVIVAL. The obligations of Pledgor under this SECTION 7 shall survive and continue to be in full force and effect notwithstanding (i) the execution and delivery of this Agreement and the other Loan Documents, (ii) the making of the Loans, (iii) the repayment of the Loans, (iv) the issuance of any Letter of Credit, (v) the payment in full of all interest, fees and all other obligations incurred under the Loan Documents and (vi) the termination of all obligations of Pledgee to Pledgor under all Loan Documents. 10. REMEDIES UPON DEFAULT. 10.1. Pledgor agrees that from time to time after an Event of Default shall have occurred and be continuing, Pledgee or its agent or agents shall have the right: (a) to require Pledgor to deliver to Pledgee such further evidence of the irrevocable proxy granted to Pledgee pursuant to SECTION 3 of this Agreement and such further irrevocable proxies to vote the Pledged Collateral as Pledgee may request; 20 EXHIBIT A (b) to transfer all or any part of the Pledged Collateral into the flame of Pledgee or its nominee, with or without disclosing that such Pledged Collateral is subject to the lien and security interest under this Agreement; (c) to enforce collection of any of the Pledged Collateral by suit or otherwise, and surrender, release or exchange all or any part of the Pledged Collateral or compromise or extend or renew for any period (whether or not longer than the original period) any obligations of any nature of any party with respect to the Pledged Collateral; (d) to sell all or any part of the Pledged Collateral at a price and using such methods (including public or private sale) as may be determined at the sole discretion of Pledgee and without notice to Pledgor, or, if such waiver of notice is invalid at law, and notice of the disposition of such Pledged Collateral is required under applicable law, upon five (5) days' written notice (which Pledgor agrees is reasonable notification within the meaning of Section 9-504(3) of the Uniform Commercial Code in the State of Illinois); (e) to bid on or purchase any of the Pledged Collateral at any sale and restrict the eligibility of prospective offerees and purchasers at any sale; (f) to conduct, adjourn, or cancel any public or private sale; (g) to sell the Pledged Collateral on credit; and (h) if such sale is upon credit, (A) to defer any delivery of excess proceeds to Pledgor until full payment for the Pledged Collateral so sold is collected, (B) to have Pledgor remain liable until full payment for the Pledged Collateral so sold is collected, and (C) to retain the Pledged Collateral or a security interest in the Pledged Collateral. 10.2. Pledgee shall apply the net proceeds of the sale of the Pledged Collateral pursuant to SECTION 8(a), after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the safekeeping or otherwise of any and all of the Pledged Collateral or in any way relating to the rights of Pledgee under this Agreement, including reasonable attorneys' fees and expenses, to the payment, in whole or in part, of the Obligations in such order as Pledgee may elect, and only after so applying such net proceeds and after the payment by Pledgee of any other amount required by any provision of law, including, without limitation, the Uniform Commercial Code as in effect in the State of Illinois, need Pledgee account for the surplus, if any, to Pledgor. Pledgor shall be liable for any deficiency remaining after such sale of the Pledged Collateral. 10.3. Any purchaser of the Pledged Collateral at any such sale shall after such sale hold the same absolutely free from any claim or right of any kind, including any equitable right of redemption of Pledgor. Pledgor specifically waives all rights of redemption, stay or appraisal which Pledgor has or may have under any rule of law or statute now existing or hereafter adopted. Pledgor will at the request of Pledgee execute any and all documents or instruments which Pledgee deems desirable to evidence Pledgee's rights as set forth above. 10.4. Pledgor further agrees that Pledgee shall be entitled to exercise all of the rights and remedies available to a secured party under the Uniform Commercial Code of the State of Illinois and all rights and remedies available to it under the Credit Agreement, this Agreement and all other Loan Documents. Pledgor further agrees to waive and agrees not to assert any rights, 21 EXHIBIT A privileges or defenses which Pledgor may acquire or be entitled to exercise under the Uniform Commercial Code of the State of Illinois. 10.5. Pledgor recognizes that Pledgee may effect one or more private sales of the Pledged Collateral to a restricted group of offerees and purchasers who fulfill certain suitability standards and who agree, among other things, to acquire the Pledged Collateral for their own account for investment and not for distribution or resale. Pledgor consents to private sales so made even though such sales may be at prices and upon other terms less favorable than if the Pledged Collateral were sold at public sales. Pledgor agrees that Pledgee shall have no obligation to delay sale of the Pledged Collateral for the period of time necessary to permit the offering and sale of the Pledged Collateral to be registered for sale under applicable laws. Pledgor consents that private sales made under the foregoing circumstances will be deemed to have been made in a commercially reasonable manner, and that Pledgee shall not be liable or accountable to Pledgor for any discount allowed by reason of the fact that such Pledged Collateral is sold in compliance with any such limitation or restriction. In lieu of exercising the power of sale conferred upon it by this Agreement, Pledgee may proceed by a suit or suits at law or in equity to foreclose and sell the Pledged Collateral. Pledgor agrees that Pledgee shall not be liable to Pledgor for any loss in the value of the Pledged Collateral by reason of any delay in the sale of the Pledged Collateral. 11. EXPENSES. Pledgor agrees to reimburse promptly Pledgee (a) for all out-of-pocket costs and expenses, including, without limitation, due diligence and audit expenses and reasonable fees and expenses of auditors, attorneys (which attorneys may be Pledgee's employees and including, without limitation, Mayer, Brown & Platt, special counsel for Pledgee) and other advisors, expended or incurred in the preparation, review, negotiation, execution and delivery, and filing and recording as necessary, of this Agreement or in amending or waiving provisions of this Agreement and other agreements or in obtaining advice from auditors, attorneys and other advisors regarding its rights and responsibilities under this Agreement and such other documents, (b) for all costs and expenses, including, without limitation, reasonable fees and expenses of auditors, attorneys (which attorneys may be Pledgee's employees) and other advisors, expended or incurred by Pledgee after a Default or Event of Default in collecting any sum which becomes due under this Agreement, in negotiations with respect to restructuring or "working out" the credit facilities or in the protection, perfection, preservation and enforcement of any and all rights of Pledgee in connection with this Agreement, including, without limitation, the fees and costs incurred in any out-of-court work-out or bankruptcy or reorganization proceeding and (c) for all costs and expenses, including, without limitation, reasonable fees and expenses of auditors, attorneys (which attorneys may be Pledgee's employees) and other advisors, expended or incurred by Pledgee for the custody, preservation or sale of, collection from or other realization upon, any of the Pledged Collateral under this Agreement, or the failure by Pledgor to perform or observe any of the provisions of this Agreement. 12. SECURITY INTEREST ABSOLUTE. All rights of Pledgee and security interests granted under this Agreement and all obligations of Pledgor under this Agreement shall be absolute and unconditional irrespective of: 12.1. Any lack of validity or enforceability of the Credit Agreement, any other Loan Document or any other agreement or instrument relating to any of the foregoing; 12.2. Any proceeding under any bankruptcy, reorganization, arrangement of debt, insolvency, readjustment of debt or receivership having been filed by or against Pledgor; 22 EXHIBIT A 12.3. Any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or consent to any departure from the Credit Agreement or any other Loan Document; 12.4. Any exchange, release or non-perfection of any other collateral, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the obligations or obligations of Pledgor under this Agreement; 12.5. Any law, regulation or order of any jurisdiction affecting any term of any of the Obligations or Pledgee's rights with respect to any of the Obligations or the Pledged Collateral; or 12.6. Any other circumstances which might otherwise constitute a defense available to, or a discharge of, the Pledgor in respect of the obligations or of this Agreement. Pledgor waives any requirement that Pledgee exhaust any right or take any action against the Pledgor, any guarantor of the obligations or any collateral security and any duty on Pledgee's part to disclose to Pledgor any matter, fact or thing related to the business, operations or conditions (financial or otherwise) of the Pledgor or its property, whether now or later known by Pledgee. 13. WAIVERS. The Pledgor waives all setoffs and counterclaims and all presentments, demands for performance, notices of nonperformance, protests, notices of protest, notices of dishonor, and diligence with respect to the Obligations and the obligations of the Pledgor hereunder and the filing of any claims with a court in the event of receivership, insolvency or bankruptcy of the Pledgor. The Pledgor further waives all notices that the principal amount, any payment or any portion thereof, any interest or any other amount on all or any part of the obligations is due, notices of any and all proceedings to collect from the Pledgor, any endorser or any other guarantor of all or any part of the obligations, or from any other Person, and, to the extent permitted by law, notices of exchange, sale, surrender or other handling of any other security given to Pledgee to secure payment of the Obligations. The Pledgor consents and agrees that Pledgee shall be under no obligation to marshall any assets in favor of the Pledgor or against or in payment of any or all of the Obligations. 14. AMENDMENTS, WAIVERS AND CONSENTS. No amendment or waiver of any provision of this Agreement nor consent to any departure by Pledgor therefrom shall be effective unless the same shall be in writing and signed by the Pledgee. No failure on the part of Pledgee to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. 15. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon Pledgor, its successors and assigns, and shall inure to the benefit of and be enforceable by Pledgee and its respective successors and assigns and any of Pledgee's participants; provided, however, that Pledgor may not assign or transfer its rights or obligations under this Agreement without the prior written consent of Pledgee, and no such consent shall in any event relieve Pledgor of its obligations hereunder. Without limiting the generality of the foregoing sentence, if, in compliance with the terms of the Credit Agreement, Pledgee assigns or otherwise transfers the Loans, or sells participations in any interest therein, to any other Person, such other Person shall thereupon become vested, to the extent set forth in the agreement evidencing such assignment, transfer or participation, with all the rights in respect thereof granted to Pledgee. 23 EXHIBIT A 16.

DEFAULT REMEDIES. 10.1. Notwithstanding any provision of any document or instrument evidencing or relating to any Liability, upon the occurrence and during the continuance of any Event of Default specified in Section 8.1 of the Credit Agreement, Secured Party at its option may declare the Liabilities immediately due and payable without notice or demand of any kind (provided that, upon the occurrence of any Event of Default specified in Section 8.1(g) of the Credit Agreement, 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, the Credit Agreement, the Guaranty, any related document or instrument (including without limitation any pertaining to Collateral), and at law or in equity. 57 EXHIBIT F 10.2. 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 the State where the main banking office of Secured Party or any Collateral is located, Secured Party may, in its sole discretion: (a) 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 (b) 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 reasonably deem appropriate. The 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 purchaser(s) 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, and 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. 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 Secured Party's intention to make any such public or private sale or sales. 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. The proceeds of sale of Collateral sold pursuant hereto shall be applied by Secured Party in such order as it shall determine. 10.3. 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" (as defined below), 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 58 EXHIBIT F 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.

(together with its successors and assigns, the "Debtor") and the Bank, the Bank has agreed, subject to the terms and conditions therein, to make Loans and other financial accommodations to the Debtor from time to time; WHEREAS, the Guarantor is a shareholder of the Debtor and will derive both direct and indirect economic benefit from the Loans and other financial accommodations made to the Debtor under the Credit Agreement; and WHEREAS, the Bank has required, as a condition to it entering into the Eighth Amendment to the Credit Agreement dated the date hereof, that the Guarantor execute and deliver this Guaranty; NOW THEREFORE, for and in consideration of the foregoing and of any financial accommodations or extensions of credit (including, without limitation, any loan or advance by renewal, refinancing or extension of the agreements described hereinabove or otherwise) heretofore, now or hereafter made to or for the benefit of the Debtor pursuant to the Credit Agreement or any other agreement, instrument or document executed pursuant to or in connection therewith, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Guarantor agrees as follows: 1. GUARANTY OF PAYMENT. The Guarantor hereby unconditionally guarantees the full and prompt payment when due, whether by acceleration or otherwise, and at all times thereafter, of all obligations of the Debtor to the Bank pursuant to the terms of the Credit Agreement, howsoever created, arising or evidenced, whether direct or indirect, absolute or contingent, or now or hereafter existing, or due or to become due (all such obligations, together with any extensions or renewals thereof, being hereinafter collectively called the "Liabilities"), and the Guarantor further agrees to pay all reasonable expenses (including reasonable attorneys' and legal assistants' fees (which attorneys and legal assistants may be employees of the Bank) and legal expenses) paid or incurred by the Bank in endeavoring to collect the Liabilities, or any part thereof, and in enforcing this Guaranty. The right of recovery against the Guarantor is unlimited. 65 EXHIBIT G 2. PRIMARY LIABILITY OF THE GUARANTOR. The Guarantor agrees that this Guaranty may be enforced by the Bank without the necessity at any time of resorting to or exhausting any other security or collateral. This is a guaranty of payment and not merely of collection. 3. ACCELERATION OF THE TIME OF PAYMENT OF AMOUNT PAYABLE UNDER GUARANTY. The Guarantor agrees that, in the event of the death, incompetency, dissolution or insolvency of the Debtor or the Guarantor, as applicable, or the inability of the Debtor or the Guarantor to pay its or his, as the case may be, debts as they mature, or an assignment by the Debtor or the Guarantor for the benefit of creditors, or the institution of any proceeding by or against the Debtor or the Guarantor alleging that the Debtor or the Guarantor is insolvent or unable to pay its or his, as the case may be, debts as they mature, and if such event shall occur at a time when any of the Liabilities may not then be due and payable, the Guarantor will pay to the Bank forthwith the full amount which would be payable hereunder by the Guarantor if all of the Liabilities were then due and payable. 4. SECURITY INTEREST IN DEPOSITS AND OTHER PROPERTY. To secure all obligations of the Guarantor hereunder, the Bank shall have a lien upon and security interest in (and may, without demand or notice of any kind, at any time and from time to time when any amount shall be due and payable by the Guarantor hereunder, appropriate and apply toward the payment of such amount, in such order of application as the Bank may elect) any and all balances, credits, deposits (general or special, time or demand, provisional or final), accounts or moneys of or in the name of the Guarantor now or hereafter with the Bank and any and all property of every kind or description of or in the name of the Guarantor now or hereafter, for any reason or purpose whatsoever, in the possession or control of, or in transit to, the Bank or any agent or bailee for the Bank. All obligations of the Guarantor shall also be secured by any and all other property in which the Bank now or hereafter has a lien or security interest and which may be or become collateral for the payment of such obligations by reason of the general description of secured obligations contained in the security agreement or other agreement or instrument, creating such lien or security interest, including the Guarantor Pledge Agreement. 5. CONTINUING GUARANTY. This Guaranty shall in all respects be a continuing, absolute and unconditional guaranty, and shall remain in full force and effect (notwithstanding, without limitation, the death or incompetency of the Guarantor or that at any time or from time to time all of the Liabilities may have been paid in full), subject to discontinuance as to the Guarantor only upon actual receipt by the Bank of payment in full of the Liabilities. 6. RESCISSION OR RETURN OF PAYMENT ON LIABILITIES. The Guarantor further agrees that, if at any time all or any part of any payment theretofore applied by the Bank to any of the Liabilities is or must be rescinded or returned by the Bank for any reason whatsoever (including, without limitation, the insolvency, bankruptcy or reorganization of the Debtor), such Liabilities shall, for the purposes of this Guaranty, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence, notwithstanding such application by the Bank, and this Guaranty shall continue to be effective or be reinstated, as the case may be, as to such Liabilities, all as though such application by the Bank had not been made. 7. BANK PERMITTED TO TAKE CERTAIN ACTIONS. The Bank may, from time to time (but shall not be obligated to), before any discontinuance of this Guaranty, at its sole discretion and 66 EXHIBIT G without notice to the Guarantor, take any or all of the following actions: (a) retain or obtain a security interest in any property of any person to secure any of the Liabilities or any obligation hereunder; (b) retain or obtain the primary or secondary obligation of any obligor or obligors, in addition to the Guarantor, with respect to any of the Liabilities; (c) extend or renew for one or more periods (whether or not longer than the original period), alter or exchange any of the Liabilities, or release or compromise any obligation of the Guarantor or any obligation of any nature of any other obligor with respect to any of the Liabilities; (d) release its security interest in, or surrender, release or permit any substitution or exchange for, all or any part of any property securing any of the Liabilities or any obligation hereunder, or extend or renew for one or more periods (whether or not longer than the original period) or release, compromise, alter or exchange any obligations of any nature of any obligor with respect to any such property; and (e) resort to the Guarantor for payment of any of the Liabilities, whether or not the Bank (i) shall have resorted to any property securing any of the Liabilities or any obligation hereunder or (ii) shall have proceeded against any other obligor primarily or secondarily obligated with respect to any of the Liabilities (all of the actions referred to in preceding clauses (i) and (ii) being hereby waived by the Guarantor). 8. APPLICATION OF PAYMENTS. Any amounts received by the Bank from whatsoever source on account of the Liabilities may be applied by it toward the payment of such of the Liabilities, and in such order of application, as the Bank may from time to time elect. 9. SUBROGATION. Until such time as this Guaranty shall have been discontinued as to the Guarantor and the Bank shall have received payment of the full amount of all of the Liabilities and of all obligations of the Guarantor, no payment made by or for the account of the Guarantor pursuant to this Guaranty shall entitle the Guarantor by subrogation or otherwise to any payment by the Debtor or from or out of any property of the Debtor, and the Guarantor shall not exercise any right or remedy against the Debtor or any property of the Debtor by reason of any performance by the Guarantor of this Guaranty. 10.

WAIVER AND MODIFICATIONS. No delay on the part of the Bank in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Bank of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy; nor shall any modification or waiver of any of the provisions of this Guaranty be binding upon the Bank except as expressly set forth in a writing duly signed and delivered on behalf of the Bank. 14. OBLIGATIONS UNDER GUARANTY. No action of the Bank permitted hereunder shall in any way affect or impair the rights of the Bank and the obligations of the Guarantor under this Guaranty. For the purposes of this Guaranty, Liabilities shall include all obligations of the Debtor to the Bank as set forth in Section 1 above, notwithstanding any right or power of the Debtor or anyone else to assert any claim or defense as to the invalidity or unenforceability of any such obligation, and no such claim or defense shall affect or impair the obligations of the Guarantor hereunder.

If Borrower wishes to borrow funds at LIBOR or if Borrower wishes to change the rate of interest on any advance, within the limits described above, from the Prime Rate to LIBOR, it shall, not less than three banking days of Lender prior to the banking day of the Lender on which such rate is to take effect, give Lender written or telephonic notice thereof, which shall be irrevocable. Such notice shall specify the advance to which LIBOR is to apply, and, in addition, the desired LIBOR maturity period of one, three, or six months (but not to exceed the maturity date of this Agreement). (ii) FAILURE TO NOTIFY. If Borrower does not notify Lender at the expiration of a selected maturity period with respect to any principal outstanding at LIBOR, then in the absence of such notice 87 EXHIBIT L Borrower shall be deemed to have elected to have such principal accrue interest after the respective LIBOR maturity period at the Prime Rate.

If any such payment of interest at LIBOR falls due on a day when Lender is not open in both Chicago and London, payment shall be made on the next day the Lender is open in both Chicago and London; however, if such day would be in the following month, such interest shall be paid on the last day Lender is open in both Chicago and London in the month when the interest payment `is due. After maturity of any installment, interest shall be payable upon demand. (e) ADDITIONAL PROVISIONS WITH RESPECT TO LIBOR. The selection by Borrower of LIBOR and the maintenance of advances at such rate shall be subject to the following additional terms and conditions: (i) AVAILABILITY OF DEPOSITS AT A DETERMINABLE RATE. If, after Borrower has elected to borrow or maintain any advance at LIBOR, Lender notifies Borrower that: (A) United States dollar deposits in the amount and for the maturity requested are not available to Lender in the London interbank market, or (B) Reasonable means do not exist for Lender to determine LIBOR for the amount and maturity requested, all as determined by Lender in its sole discretion, then the principal subject to LIBOR shall accrue or shall continue to accrue interest at the Prime Rate. (ii) PROHIBITION OF MAKING, MAINTAINING, OR REPAYMENT OF PRINCIPAL AT LIBOR. If any treaty, statute, regulation, interpretation thereof, or any directive, guideline, or otherwise by a central bank or fiscal authority (whether or not having the force of law) shall either prohibit or extend the time at which any principal subject to LIBOR may be purchased, maintained, or repaid, all as determined by Lender in its sole discretion, then on and as of the date the prohibition becomes effective, the principal subject to that prohibition shall continue at the Prime Rate. (iii) PAYMENTS OF PRINCIPAL AND INTEREST TO BE NET OF ANY TAXES OR COSTS. All payments of principal and interest shall be made net of any taxes and costs incurred by Lender resulting from having principal outstanding hereunder at LIBOR, as determined by the Lender in its sole discretion. 88 EXHIBIT L Without limiting the generality of the preceding obligation, illustrations of such taxes and costs are: (A) Taxes (or the withholding of amounts for taxes) of any nature whatsoever including income, excise, and interest equalization taxes (other than income taxes imposed by the United States or any state thereof on the income of Lender), as well as all levies, imposts, duties, or fees whether now in existence or resulting from a change in, or promulgation of, any treaty, statute, regulation, interpretation thereof, or any directive, guideline, or otherwise, by a central bank or fiscal authority (whether or not having the force of law) or a change in the basis of, or time of payment of, such taxes and other amounts resulting therefrom; (B) Any reserve or special deposit requirements (other than any included within the definition of LIBOR set forth hereinabove) against assets or liabilities of, or deposits with or for the account of, Lender with respect to principal outstanding at LIBOR (including those imposed under Regulation D of the Federal Reserve Board) or resulting from a change in, or the promulgation of, such requirements by treaty, statute, regulation, interpretation thereof, or any directive, guideline, or otherwise by a central bank or fiscal authority (whether or not having the force of law); (C) Any other costs resulting from compliance with treaties, statutes, regulations, interpretations, or any directives or guidelines, or otherwise by a central bank or fiscal authority (whether or not having the force of law); (D) Any loss (including loss of anticipated profits) or expense incurred by reason of the liquidation or re-employment of deposits acquired by Lender to make advances or maintain principal outstanding at LIBOR: (1) As the result of a voluntary prepayment at a date other than the maturity date selected for principal outstanding at LIBOR; or (2) As the result of a mandatory repayment at a date other than the maturity date selected for principal outstanding at LIBOR as a result of Borrower exceeding any applicable borrowing base or as the result of the occurrence of an Event of Default and the acceleration of any portion of the indebtedness hereunder; or (3) As the result of a prohibition on making, maintaining, or repaying principal outstanding at LIBOR. If Lender incurs any such taxes or costs, Borrower, upon demand in writing specifying such taxes and costs, shall promptly pay them; save for manifest 89 EXHIBIT L error Lender's specification shall be presumptively deemed correct. All advances made or carried at LIBOR shall be conclusively deemed to have been funded by or on behalf of Lender in the London interbank market by the purchase of deposits corresponding in amount and maturity to the amount and interest periods selected (or deemed to have been selected) by Borrower hereunder. (f) PAYMENT AND PREPAYMENT. Borrower may from time to time prepay any principal bearing interest at the Prime Rate in whole or in part at any time and may prepay any amounts bearing interest at LIBOR at the end of the maturity period chosen or deemed elected by Borrower applicable to the advance or portion of the advance being prepaid, without premium or penalty; provided that any partial prepayment shall be in an aggregate principal amount of at least $10,000. Any prepayment of an amount bearing interest at LIBOR at a date other than the maturity date applicable to the advance or the portion of the advance being prepaid shall be subject to the provisions of Section (e) above. All prepayments of principal shall include interest accrued to the date of prepayment on the principal amount being prepaid. 1.3 EXHIBIT A TO THE AGREEMENT.
