(v) buy the Collateral, or any portion thereof, at any public sale;

warranties of title or the like. Further, if Secured Party sells any of the Collateral on credit, Debtor will be credited only with payments actually made by the purchaser, received by Secured Party and applied to the Indebtedness. In the event the purchaser fails to pay for the Collateral, Secured Party may resell the Collateral and Debtor shall be credited with the proceeds of the sale. Debtor agrees that in the event Debtor or any Obligor is entitled to receive any notice under the Code, as it exists in the state governing any such notice, of the sale or other disposition of any Collateral, reasonable notice shall be deemed given when such notice is deposited in a depository receptacle under the care and custody of the United States Postal Service, postage prepaid, at such party’s address set forth on the first page hereof, ten (10) days prior to the date of any public sale, or after which a private sale, of any of such Collateral is to be held. Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. 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.

(i) to the repayment or reimbursement of the reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) incurred by Secured Party in connection with (A) the administration of the Loan Documents, (B) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, the Collateral, and (C) the exercise or enforcement of any of the rights and remedies of Secured Party hereunder;

(ii) to the payment or other satisfaction of any liens and other encumbrances upon the Collateral;

(iii) to the satisfaction of the Indebtedness;

(iv) by holding such cash and proceeds as Collateral;

(v) to the payment of any other amounts required by applicable law (including without limitation, Section 9.615(a)(3) of the Code or any other applicable statutory provision); and

(vi) by delivery to Debtor or any other party lawfully entitled to receive such cash or proceeds whether by direction of a court of competent jurisdiction or otherwise.

(c) Deficiency. In the event that the proceeds of any sale of, collection from, or other realization upon, all or any part of the Collateral by Secured Party are insufficient to pay all amounts to which Secured Party is legally entitled, Obligor and any party who guaranteed or is otherwise obligated to pay all or any portion of the Indebtedness shall be liable for the deficiency, together with interest thereon as provided in the Loan Documents, to the full extent permitted by the Code.

(d) Non-Judicial Remedies. In granting to Secured Party the power to enforce its rights hereunder without prior judicial process or judicial hearing, Debtor expressly waives, renounces and knowingly relinquishes any legal right which might otherwise require Secured Party to enforce its rights by judicial process. Debtor recognizes and concedes that non-judicial remedies are consistent with the usage of trade, are responsive to commercial necessity and are the result of a bargain at arm’s length. Nothing herein is intended to prevent Secured Party or Debtor from resorting to judicial process at either party’s option.

(e) Other Recourse. Debtor waives any right to require Secured Party to proceed against any third party, exhaust any Collateral or other security for the Indebtedness, or to have any third party joined with Debtor in any suit arising out of the Indebtedness or any of the Loan Documents, or pursue any other remedy available to Secured Party. Debtor further waives any and all notice of acceptance of this Agreement and of the creation, modification, rearrangement, renewal or extension of the Indebtedness. Debtor further waives any defense arising by reason of any disability or other defense of any third party or by reason of the cessation from any cause whatsoever of the liability of any third party. Until all of the Indebtedness shall have been paid in full, Debtor shall have no right of subrogation and Debtor waives the right to enforce any remedy which Secured Party has or may hereafter have against any third party, and waives any benefit of and any right to participate in any other security whatsoever now or hereafter held by Secured Party. Debtor authorizes Secured Party, and without notice or demand and without any reservation of rights against Debtor and without affecting Debtor’s liability hereunder or on the Indebtedness to (i) take or hold any other property of any type from any third party as security for the Indebtedness, and exchange, enforce, waive and release any or all of such other property, (ii) apply such other property and direct the order or manner of sale thereof as Secured Party may in its discretion determine, (iii) renew, extend, accelerate, modify, compromise, settle or release any of the Indebtedness or other security for the Indebtedness, (iv) waive, enforce or modify any of the provisions of any of the Loan Documents executed by any third party, and (v) release or substitute any third party.

No waiver of any provision hereof or consent to any departure by Debtor therefrom shall be effective unless the same shall be in writing and signed by Secured Party and then such waiver or consent shall be effective only in the specific instances, for the purpose for which given and to the extent therein specified.
