Each Grantor will keep its Inventory in good and marketable condition, at its own expense. SECTION 8. Insurance. (a) The Grantors shall, at their own expense, maintain insurance with respect to the Collateral in such amounts, against such risks, in such form and with such insurers, as is typical for businesses similarly situated. After an Event of Default shall have occurred and be continuing, the Grantors shall cause each policy for property damage insurance covering the Inventory and Equipment to provide that all insurance proceeds in respect of loss, damage or destruction of any such Inventory or Equipment in excess of $100,000 per occurrence or in any related series of occurrences or $300,000, in the aggregate, in any calendar year, are to be paid directly to the Guarantor. Such amounts shall, subject to the limitations set forth in this subsection (a) and in subsection (c) of this Section 8 and after deducting from such proceeds the expenses, if any, incurred by the Guarantor in the collection or handling thereof, be returned to such Grantor, which Grantor shall make or cause to be made the necessary repairs to or replacements of such Inventory or Equipment. All such replacements or repairs shall be made with materials and property of substantially as good a quality as existed before such loss, damage or destruction, and such Grantor shall commence the replacement or repair of such property as soon as practicable and proceed diligently with it until completion. Plans for any such repair or replacement shall be reasonably satisfactory to the Guarantor and shall be subject to the reasonable approval of the Guarantor prior to the release of insurance proceeds to the applicable Grantor. Each such property policy covering the Equipment or Inventory shall in addition to the foregoing (i) name the appropriate Grantor and the Guarantor as insured parties thereunder (without any representation or warranty by or obligation upon the Guarantor) as their interests may appear, (ii) provide that there shall be no recourse against the Guarantor for payment of premiums or other amounts with respect thereto, (iii) provide that at least 30 days' prior written notice of cancellation of or lapse shall be given to the Guarantor by the insurer, and (iv) contain a clause or endorsement stating that the interest of the Guarantor shall not be impaired or invalidated by any act or neglect of the Grantor insured thereunder or the owner of any premises for purposes more hazardous than are permitted by such policy. After an Event of Default shall have occurred and be continuing, each such property policy shall also contain the agreement by the insurer that losses thereunder shall be payable to the Guarantor, subject to the terms and limitations set forth in the first sentence of this Section 8, notwithstanding any action, inaction or breach of representation or warranty by the Grantor. The Grantors shall, if so requested by the Guarantor, deliver to the Guarantor duplicate policies of such insurance and, as often as the Guarantor may reasonably request, a report of a reputable insurance broker with respect to such insurance. Further, the Grantors shall, at the request of the Guarantor, duly execute and deliver 7 8 instruments of assignment of such insurance policies to comply with the requirements of Section 6 and cause the insurers to acknowledge notice of such assignment. (b) Reimbursement under any liability insurance maintained by any Grantor pursuant to this Section 8 may be paid directly to the Person who shall have incurred liability covered by such insurance. (c) Notwithstanding anything contained herein to the contrary, upon the occurrence and during the continuance of an Event of Default, any loss, damage or destruction of any Inventory or Equipment in excess of $1,000,000 in any one occurrence or in any related series of occurrences any insurance proceeds in respect of such lost, damaged or destroyed Equipment or Inventory shall be paid to the Guarantor and, at the Guarantor's sole option, may be applied by the Guarantor (after deducting from such proceeds the expenses, if any, incurred by the Guarantor in the collection or handling thereof) as specified in Section 14(b). Notwithstanding anything contained in this Agreement to the contrary, if any of the Grantors shall receive any insurance proceeds which, pursuant to the terms of this Section 8, are required to be delivered to the Guarantor, such Grantor (1) shall be deemed to be holding such proceeds in trust for the Guarantor, (2) shall segregate such proceeds from such Grantor's funds and (3) shall promptly upon its receipt thereof remit such proceeds to the Guarantor in the same form as received by such Grantor, other than for any necessary endorsements. SECTION 9. As to Accounts. (a) Each Grantor shall keep its chief place of business and chief executive office and the office where it keeps its records concerning the Accounts, and the originals of all chattel paper that evidence Accounts, at the location therefor specified in Section 5(a) or, upon 30 days' prior written notice to the Guarantor, at any other locations in jurisdictions where all actions required by Section 6 shall have been taken with respect to the Accounts. The Grantors will hold and preserve such records and chattel paper and will permit the Guarantor or its representatives at any time during normal business hours to inspect and make abstracts from such records and chattel paper. (b) Except as otherwise provided in this subsection (b), the Grantors shall continue to collect, at their own expense, all amounts due or to become due the Grantors under the Accounts. In connection with such collections, the Grantors may take such action as the Grantors or the Guarantor may deem necessary or advisable to enforce collection of the Accounts; provided, however, that the Guarantor shall have the right at any time, upon the occurrence and during the continuance of an Event of Default and upon written notice to the Grantors of its intention to do so, to notify the account debtors or obligors under any Accounts of the assignment of such Accounts to the Guarantor and to direct such account debtors or obligors to make payment of all amounts due or to become due to the Grantors thereunder directly to the Guarantor and, upon such notification and at the expense of the Grantors, to enforce collection of any such Accounts, and to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as the Grantors might have done. After receipt by the Grantors of the notice from the Guarantor referred to in the proviso to the preceding sentence, (i) all amounts and proceeds (including instruments) received by any Grantor in respect of the Accounts shall be received in trust for the benefit of the Guarantor hereunder, shall be segregated 8 9 from other funds of such Grantor and shall be forthwith paid over to the Guarantor in the same form as so received (with any necessary endorsement) and either (A) released to the applicable Grantor so long as no Event of Default shall have occurred and be continuing or (B) if any Event of Default shall have occurred and be continuing, applied as provided by Section 14(b), and (ii) the Grantors shall not adjust, settle or compromise the amount or payment of any Account, release wholly or partly any account debtor or obligor thereof, or allow any credit or discount thereon. SECTION 10. Transfers and Other Liens. The Grantors shall not (i) sell, assign (by operation of law or otherwise) or otherwise dispose of, or grant any option with respect to, any of the Collateral, except Inventory and Equipment in the ordinary course of business and except as otherwise expressly permitted under the terms of the Reimbursement Agreement, or (ii) create or permit to exist any lien, security interest, option or other charge or encumbrance upon or with respect to any of the Collateral, except for Permitted Liens. SECTION 11. Guarantor Appointed Attorney-in-Fact. Upon the occurrence and during the continuance of an Event of Default, each Grantor hereby irrevocably appoints the Guarantor as such Grantor's attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time in the Guarantor's discretion, to take any action and to execute any instrument which the Guarantor may deem necessary or advisable to accomplish the purposes of this Agreement (subject to the rights of the Grantors under Section 9), including, without limitation: (a) to obtain and adjust insurance required to be paid to the Guarantor pursuant to Section 8, (b) to ask, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in connection with the Collateral, (c) to receive, endorse and collect any drafts or other instruments, documents and chattel paper, in connection therewith, and (d) to file any claims or take any action or institute any proceedings which the Guarantor may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Guarantor with respect to any of the Collateral. SECTION 12. Guarantor May Perform. If any Grantor fails to perform any agreement contained herein, the Guarantor may itself perform, or cause performance of, such agreement, and the expenses of the Guarantor (including, without limitation, reasonable attorney's fees and expenses) incurred in connection therewith shall be payable by the Grantors under Section 15(b). SECTION 13. The Guarantor's Duties. The powers conferred on the Guarantor hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers.
