(f) Except as otherwise provided in this subsection (f), each Grantor shall continue to collect, at its own expense, all amounts due or to become due such Grantor under the Receivables. In connection with such collections, each Grantor may take (and, upon the occurrence and continuance of an Event of Default at the Secured Party's direction, shall take) such action as such Grantor or the Secured Party may deem necessary or advisable to enforce collection of the Receivables; provided, that the Secured Party shall have the right at any time, upon the occurrence and during the continuance of an Event of Default and upon written notice to each Grantor of its intention to do so, to notify the account debtors or obligors under any Receivables of the assignment of such Receivables to the Secured Party and to direct such account debtors or obligors to make payment of all amounts due or to become due to each Grantor thereunder directly to the Secured Party and, upon such notification and at the expense of such Grantor, to enforce collection of any such Receivables, and to adjust, settle or compromise the amount of payment thereof, in the same manner and to the same extent as each such Grantor might have done. After receipt by the -5- 6 Grantors of the notice from the Secured Party referred to in the proviso to the preceding sentence, (i) all amounts and proceeds (including instruments) received by the Grantors in respect of the Receivables shall be received in trust for the benefit of the Banks hereunder, shall be segregated from other funds of the Grantors and shall be forthwith paid over to the Secured Party in the same form as so received (with any necessary endorsement) to be held as cash collateral and either (A) released to the Grantors 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 in Section 9, and (ii) the Grantors shall not adjust, settle or compromise the amount or payment of any Receivable, or release wholly or partly any account debtor or obligor thereof, or allow any credit or discount thereon, except with the prior written consent of the Secured Party.

The Grantors shall, at their own expense, maintain insurance as provided in Section 7.03 of the Credit Agreement. SECTION 8. Transfers and Other Liens. The Grantors shall not: (a) sell, assign (by agreement, operation of law or otherwise) or otherwise dispose of any of the Collateral (other than in the ordinary course of business) or (b) create or suffer to exist any lien or security interest upon or with respect to any of the Collateral, except for the lien or security interest created by this Security Agreement and liens and security interests in favor of the Secured Party as previously disclosed to the Banks. SECTION 9. Remedies and Application of Proceeds. If any Event of Default shall have occurred and be continuing, the Secured Party may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the UCC (whether or not the UCC applies to the affected Collateral) and the Secured Party may also (a) require the Grantors to, and the Grantors hereby agree that they will at their expense and upon request of the Secured Party forthwith, assemble all or part of the Collateral as directed by the Secured Party and make it available to the Secured Party at a place to be designated by the Secured Party which is reasonably convenient to both parties and (b), without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, for cash, on credit or for future delivery, and upon -6- 7 such other terms as the Secured Party may deem commercially reasonable. The Grantors will execute and deliver such documents and take such other action as the Secured Party deems necessary or advisable in order that any sale may be made. Upon any such sale the Secured Party shall have the right to deliver and transfer to the purchase thereof the Collateral sold. The Grantors agree that, to the extent notice of sale shall be required by law, at least ten (10) days' prior written notice to the Grantors of the time and place of any public sale or the time after which any private sale is to be made or other intended disposition of any of the Collateral shall constitute reasonable notification thereof, except any Collateral which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market. The Grantors agree that such notice constitutes "reasonable notification" within the meaning of 9.504(c) of the UCC. The Secured Party shall not be obligated to make any sale of the Collateral regardless of notice of sale having been given. The Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

SECTION 12. Limitations of the Secured Party's Duties. The powers conferred on the Secured Party hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for reasonable care in the custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Secured Party shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral. The Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Secured Party accords it own property, it being understood that the Secured Party shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any Collateral. SECTION 13. Indemnity and Expenses. (a) The Grantors shall indemnify the Secured Party and any Affiliate thereof and their respective directors, officers, employees and agents from, and hold each of them harmless against, any and all losses, liabilities, claims or damages (including reasonable legal fees and expenses) to which any of them may become subject, insofar as such losses, liabilities, claims or damages arise out of or result from (i) this Security Agreement, the Credit Agreement or any of the loan documents executed in connection herewith or (ii) any investigation, litigation or other proceeding (including any threatened investigation or proceeding) relating to the foregoing, and the Grantors shall reimburse the Secured Party and each Affiliate thereof and their respective directors, officers, employees and agents, upon demand for any expenses (including legal fees) reasonably incurred in connection with any such investigation or proceeding, but excluding any such losses, liabilities, claims, damages or expenses incurred by reason of the gross negligence or willful misconduct of the person to be indemnified. IT IS THE EXPRESS INTENTION OF THE GRANTORS THAT EACH PERSON TO BE INDEMNIFIED HEREUNDER SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS OR DAMAGES AS LIMITED IN THE PRECEDING SENTENCE ARISING OUT OF OR RESULTING FROM THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH PERSON.

SECTION 15. Termination; Reinstatement.

(d) Should any clause, sentence, paragraph, subsection or Section of this Security Agreement be judicially declared to be invalid, unenforceable or void, such decision will not have the effect of invalidating or voiding the remainder of this Security Agreement, and the parties hereto agree that the part or parts of this Security Agreement so held to be invalid, unenforceable or void will be deemed to have been stricken herefrom by the parties hereto, and the remainder will have the same force and effectiveness as if such stricken part or parts had never been included herein. (e) No failure on the part of the Secured Party 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.
