(b) Pledgor (i) shall (A) maintain at all times the pledge of the Collateral to Secured Party and Secured Party’s perfected first priority lien on the Collateral; and (B) defend the Collateral and Secured Party’s perfected first priority lien thereon and pledge thereof against all valid claims and demands of all Persons at any time and pay all reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) and (ii) except as permitted by Section 2.2(b) , shall not sell, lease, transfer, pledge, encumber, restrict, assign or otherwise dispose of any of the Collateral or any interest therein or create, incur, assume or suffer to exist any lien on the Collateral or any interest therein (except pursuant hereto or with Secured Party’s prior written consent).

SECTION 4
EVENTS OF DEFAULT

SECTION 5
RIGHTS AND REMEDIES

5.1. Rights and Remedies .

(a) In addition to the provisions set forth in this Agreement, upon the occurrence and during the continuation of an Event of Default, Secured Party shall have all rights, powers, options and remedies provided for in the Amended Note and/or in this Agreement, under the UCC or at law or in equity, including, without limitation, to the fullest extent permitted by applicable law, the right to, which Pledgor agrees to be

commercially reasonable, (i) apply the Collateral to reduce the obligations of the Pledgor under the Amended Note, (ii) foreclose the liens created hereunder, (iii) realize upon, take possession of and/or sell the Collateral, with or without judicial process, at public or private sales or at any broker’s board or on any securities exchange or otherwise with or without a disclaimer of warranties as to the Collateral sold, (iv) exercise all rights and powers with respect to the Collateral as Pledgor might exercise in its sole discretion, including, without limitation, to (1) relinquish or abandon any Collateral or any lien thereon, (2) vote all or any part of the Collateral and otherwise act with respect thereto as though it were the outright owner thereof, (3) settle, adjust, compromise and arrange all claims and demands whatsoever in relation to all or any part of the Collateral, (4) execute all such contracts, agreements, deeds, documents and instruments, bring, defend and abandon all such actions, suits and proceedings, and take all actions in relation to all or any part of the Collateral, and/or (5) appoint managers, sub-agents and officers for any of the purposes mentioned in the foregoing provisions of this Section and dismiss the same, and/or (v) collect and send notices regarding the Collateral, with or without judicial process.  Secured Party shall have the right in its sole discretion to determine which rights and/or remedies Secured Party may at any time pursue, relinquish, subordinate or modify, and such determination will not in any way modify or affect any of Secured Party’s rights, liens or remedies under the Amended Note, this Agreement, applicable law or equity.  The enumeration of any rights and remedies in this Agreement is not intended to be exhaustive, and all rights and remedies of Secured Party described in this Agreement are cumulative and are not alternative to or exclusive of any other rights or remedies that Secured Party otherwise may have.  The partial or complete exercise of any right or remedy shall not preclude any other further exercise of such or any other right or remedy.  

(b) Notwithstanding any provision of this Agreement, Secured Party, in its sole discretion, shall have the right, but not the obligation, at any time that Pledgor fails to do so, to discharge taxes, levies or liens on any of the Collateral that are in violation of this Agreement unless Pledgor is in good faith with due diligence by appropriate proceedings contesting those items.  Such expenses and advances shall be added to the obligations of the Pledgor under the Amended Note until reimbursed to Secured Party and shall be secured by the Collateral, and such payments by Secured Party shall not be construed as a waiver by Secured Party of any Event of Default or any other rights or remedies of Secured Party.

(c) Pledgor agrees that notice received by it at least ten (10) calendar days before the time of any intended public sale, or the time after which any private sale or other disposition of Collateral is to be made, shall be deemed to be reasonable notice of such sale or other disposition.  At any sale or disposition of Collateral, Secured Party may (to the extent permitted by applicable law) (i) purchase all or any part thereof free from any right of redemption by Pledgor or any other Person, which right is hereby waived and released, (ii) restrict the number of prospective bidders or purchasers and/or further restrict such prospective bidders or purchasers to Persons who will represent and agree that they are purchasing for their own account, for investment and not with a view to the distribution or resale of the Collateral, and (iii) otherwise require that such sale be conducted subject to restrictions as to such other matters as Secured Party may deem necessary in order that such sale may be effected in such manner as to comply with all applicable state and federal securities and other laws.  

(d) Pledgor hereby acknowledges that (i) notwithstanding that a higher price might be obtained for the Collateral at a public sale than at a private sale or sales, the making of a public sale of the Collateral may be subject to registration requirements under applicable securities laws and other legal restrictions, compliance with which would require such actions on the part of Pledgor, would entail such expenses and would subject Secured Party, any underwriter through whom the Collateral may be sold or any controlling person of any of the foregoing to such liabilities, as would make a public sale of the Collateral impractical, and accordingly, Pledgor hereby agrees that private sales made by Secured Party in good faith in accordance with the provisions of this Agreement may be at prices and on other terms less favorable to the Pledgor than if the Collateral were sold at a public sale, and that Secured Party shall not have any obligation to take any steps in order to permit the Collateral to be sold at a public sale, such a private sale being considered or deemed to be a sale in a commercially reasonable manner; and (ii) Secured Party is hereby authorized to comply with any limitation or restriction in connection with such sale that may be necessary in order to avoid any violation of applicable law or in order to obtain any required approval of the purchaser(s) by any governmental authority, officer or court.

5.2. Rights of Secured Party to Appoint Receiver .  Without limiting and in addition to any other rights, options and remedies Secured Party has hereunder or under the Amended Note, the UCC, at law or in equity, upon the occurrence and during the continuation of an Event of Default, Secured Party shall have the right to apply for a receiver appointed by a court of competent jurisdiction in any action taken by Secured Party to enforce its rights and remedies in order to manage, protect and preserve the Collateral and to collect all revenues and profits thereof and apply the same to the payment of all expenses and other charges of such receivership including the compensation of the receiver and to the payments as aforesaid until a sale or other disposition of such Collateral shall be finally made and consummated.

SECTION 6
MISCELLANEOUS

6.1. No Waiver of Defaults; Waiver .

(a) No course of action or dealing, renewal, waiver, release or extension of any provision of the Amended Note or this Agreement, or single or partial exercise of any such provision, or delay, failure or omission on Secured Party’s part in enforcing any such provision shall affect the liability of Pledgor or operate as a waiver of such provision or preclude any other or further exercise of such provision.  No waiver by Secured Party of any one or more defaults by any other party in the performance of any of the provisions of the Amended Note or this Agreement shall operate or be construed as a waiver of any future default, whether of a like or different nature, and each such waiver shall be limited solely to the express terms and provisions of such waiver.

(b) Except as expressly provided for herein, Pledgor hereby waives setoff, counterclaim, demand, presentment, protest, all defenses with respect to any and all instruments and all notices and demands of any description (including, without limitation, notice of acceptance hereof, credit extended, collateral received or delivered) and the pleading of any statute of limitations as a defense to any demand under the Amended Note, it being the intention that Pledgor shall remain liable under the Amended Note until the Amended Note has been fully repaid in accordance with its terms, notwithstanding any act, omission or anything else which might otherwise operate as a legal or equitable discharge of Pledgor.  Pledgor hereby waives any and all defenses and counterclaims it may have or could interpose in any action or procedure brought by Secured Party to obtain an order of court recognizing the assignment of, or lien of Secured Party in and to, any Collateral.

6.6. Severability; Captions; Counterparts; Facsimile Signature .  If any provision of this Agreement is adjudicated to be invalid under applicable laws or regulations, such provision shall be inapplicable to the extent of such invalidity without affecting the validity or enforceability of the remainder of this Agreement which shall be given effect so far as possible.  The captions in this Agreement are intended for convenience and reference only and shall not affect the meaning or interpretation of this Agreement.  This Agreement may be executed in one or more counterparts (which taken together, as applicable, shall constitute one and the same instrument) and by facsimile or electronic transmission, which such signatures shall be considered original executed counterparts.  Each party to this Agreement agrees that it will be bound by its own facsimile or electronic signature and that it accepts the facsimile or electronic signature of each other party.

6.7. Successors and Assigns .  All provisions contained in this Agreement shall be binding upon, inure to the benefit of and be enforceable by the successors and assigns of the parties hereto to the same extent as if each such successor and assign were named as a party hereto.
