Without limiting the foregoing, so long as an Event of Default has occurred and is continuing, the Secured Party shall have the right, without notice to, or the consent of, the Debtor, to do any of the following on the Debtors behalf:
 (i)  to pay or discharge any taxes or Liens levied or placed on or threatened against the Collateral;
 (ii)  to direct any party liable for any payment under any of the Collateral to make payment of any and all amounts due or to become due thereunder directly to the Secured Party or as the Secured Party directs;
 (iii)  to ask for or demand, collect, and receive payment of and receipt for, any payments due or to become due at any time in respect of or arising out of any Collateral;
 (iv)  to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to enforce any right in respect of any Collateral;
 (v)  to defend any suit, action or proceeding brought against the Debtor with respect to any Collateral;
 (vi)  to settle, compromise or adjust any suit, action or proceeding described in subsection (v) above and to give such discharges or releases in connection therewith as the Secured Party may deem appropriate;

 (viii)  generally, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral and to take, at the Secured Partys option and the Debtors expense, any actions which the Secured Party deems necessary to protect, preserve or realize upon the Collateral and the Secured Partys Liens on the Collateral and to carry out the intent of this Agreement, in each case to the same extent as if the Secured Party were the absolute owner of the Collateral for all purposes.
 The Debtor hereby ratifies whatever actions the Secured Party shall lawfully do or cause to be done in accordance with this Section 5. This power of attorney shall be a power coupled with an interest and shall be irrevocable.
  (c)  No Duty on the Secured Partys Part . The powers conferred on the Secured Party by this Section 5 are solely to protect the Secured Partys interests in the Collateral and shall not impose any duty upon it to exercise any such powers. The Secured Party shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Secured Party nor any of its officers, directors, employees or agents shall, in the absence of willful misconduct or gross negligence, be responsible to the Debtor for any act or failure to act pursuant to this Section 5.
  6.  Performance by the Secured Party of the Debtors Obligations . If the Debtor fails to per­form or comply with any of its agreements or covenants contained in this Agreement and the Secured Party performs or complies, or otherwise causes performance or compliance, with such agreement or covenant in accordance with the terms of this Agreement, then the expenses of the Secured Party incurred in connection with such performance or compliance shall be payable by the Debtor to the Secured Party on demand  and shall constitute Obligations  secured by this Agreement.
  7.  Remedies . If an Event of Default has occurred and is continuing, the Secured Party may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the foregoing, the Secured Party, without demand of performance or other demand, present­ment, protest, advertisement or notice of any kind (except any notice required by law) to or upon the Debtor or any other person (all of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances collect, receive, appropriate and realize upon any or all of the Collateral, and/or may sell, lease, assign, give an option or options to purchase, or otherwise dispose of and deliver any or all of the Collateral (or contract to do any of the foregoing), in one or more parcels at a public or private sale or sales, at any exchange, brokers board or office of the Secured Party or elsewhere upon such terms and conditions as the Secured Party may deem advisable, for cash or on credit or for future delivery without assumption of any credit risk. The Secured Party shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase all or any part of the Collateral so sold, free of any right or equity of redemption in the Debtor, which right or equity is hereby waived or released. The Secured Party shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable expenses incurred therein or in connection with the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Secured Party under this Agreement (including, without limitation, reasonable attorneys fees and expenses) to the payment in whole or in part of the Obligations, in such order as the Secured Party may elect, and only after such application and after the payment by the Secured Party of any other amount required by any provision of law, need the Secured Party account for the surplus, if any, to the Debtor. To the extent permitted by applicable law, the Debtor waives all claims, damages and demands it may acquire against the Secured Party arising out of the exercise by the Secured Party of any of its rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least ten days before such sale or other disposition. The Debtor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Secured Party to collect such deficiency.
  8.  Limitation on Duties Regarding Preservation of Collateral . The Secured Partys sole duty with respect to the custody, safekeeping and preservation of the Collateral, under Section 9207 of the UCC or otherwise, shall be to deal with it in the same manner as the Secured Party deals with similar property for its own account. Neither the Secured Party nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Debtor or otherwise.
  9.  Powers Coupled with an Interest . All authorizations and agencies contained in this Agreement with respect to the Collateral are irrevocable and are powers coupled with an interest.
  10.  No Waiver; Cumulative Remedies . The Secured Party shall not by any act (except by a written instrument pursuant to Section 12(a) hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any default under the Notes or any of the other Credit Documents or in any breach of any of the terms and conditions of this Agreement. No failure to exer­cise, nor any delay in exercising, on the part of the Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise 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. A waiver by the Secured Party of any right or remedy under this Agreement on any one occasion shall not be construed as a bar to any right or remedy which the Secured Party would otherwise have on any subsequent occasion. The rights and remedies provided in this Agreement are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law.
  11.  Termination of Security Interest . Upon satisfaction of the Debtors obligations pursuant to the Notes, the security interest granted herein shall terminate and all rights to the Collateral shall revert to the Debtor. Upon any such termination, the Secured Party shall authenticate and deliver to the Debtor such documents as the Debtor may reasonably request to evidence such termination.

In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.
