Section 5.01 Discharge Encumbrances. Secured Party may, at its option, discharge any taxes, liens, security interests or other encumbrances at any time levied or placed on the Collateral.

Section 5.04 Disclaimer of Certain Duties. The powers conferred upon Secured Party by this Agreement are to protect its interest in the Collateral and shall not impose any duty upon Secured Party to exercise any such powers.

Any such sale or transfer by Secured Party either to itself or to any other Person shall be absolutely free from any claim of right by Pledgor, including any equity or right of redemption, stay or appraisal which Pledgor has or may have under any rule of law, regulation or statute now existing or hereafter adopted. Upon any such sale or transfer, Secured Party shall have the right to deliver, assign and transfer to the purchaser or transferee thereof the Collateral so sold or transferred.

Secured Party may, at its discretion, provide for a public sale, and any such public sale shall be held at such time or times within ordinary business hours and at such place or places as Secured Party may fix in the notice of such sale.

parts thereof in any manner authorized or permitted by law or in equity, and to apply the proceeds of the same towards payment of the Obligations.

Section 6.04 Liability for Deficiency. If any sale or other disposition of Collateral by Secured Party in compliance with the Loan Documents and applicable law or any other action of Secured Party hereunder in compliance with the Loan Documents and applicable law results in reduction of the Obligations, such action will not release Pledgor from its liability to Secured Party for any unpaid Obligations, including costs, charges and expenses incurred in the liquidation of Collateral, together with interest thereon, and the same shall be immediately due and payable to Secured Party at Secured Party's address set forth in the opening paragraph hereof.

Section 6.05 Reasonable Notice. If any applicable provision of any law requires Secured Party to give reasonable notice of any sale or disposition or other action, Pledgor hereby agrees that ten days' prior written notice shall constitute reasonable notice thereof. Such notice, in the case of public sale, shall state the time and place fixed for such sale and, in the case of private sale, the time after which such sale is to be made.

Section 6.06 Pledged Securities. Upon the occurrence and during the continuance of an Event of Default:

(a) All rights of Pledgor to receive the dividends and interest payments which it would otherwise be authorized to receive and retain pursuant to Section 4.02 shall cease, and all such rights shall thereupon become vested in Secured Party who shall thereupon have the sole right to receive and hold as Collateral such dividends and interest payments, but Secured Party shall have no duty to receive and hold such dividends and interest payments and shall not be responsible for any failure to do so or delay in so doing.

Section 6.07 Non-judicial Enforcement. To the extent permitted by law, Secured Party may enforce its rights hereunder without prior judicial process or judicial hearing, and to the extent permitted by law Pledgor expressly waives any and all legal rights which might otherwise require Secured Party to enforce its rights by judicial process.
