The purchaser(s) at any such sale shall thereafter hold the same absolutely, free from any claim or right of whatever kind, including any equity of redemption, of the Borrower, any such demand, notice, claim, right or equity being hereby expressly waived and released.

The Borrower hereby waives any claims against the Agent and the Lenders arising by reason of the fact that the price at which the Collateral may have been sold at any private sale was less than the price which might have been obtained at a public sale or was less than the then total unpaid Obligations so long as such sale was conducted in a commercially reasonable manner. 5.3 All payments received after a default in this payment of the obligation shall be applied as follows: (a) First: to the payment of all fees, costs and expenses incurred by the Agent or the Lenders as a result of or in connection with the exercise of the remedies set forth herein; (b) Second: to the payment in full of the Obligations; and (c) Third: the balance, if any, of such proceeds remaining after payment in full of the foregoing items, to the Borrower or as a court of competent jurisdiction may otherwise direct. If the amount of the proceeds received from the sale or other disposition of the Collateral shall be insufficient to satisfy in full the amounts referred to in paragraphs (a) and (b) above, the Borrower shall remain and be liable for any such deficiency. 5.4 Borrower shall pay all costs and expenses, including reasonable attorneys fees and disbursements incurred in connection with the Lenders' enforcement and exercise of any of their rights and remedies as herein provided, whether or not suit is commenced by the Lenders. 5.5 Upon the default in the payment of an Obligation, the Agent and/or its agents may immediately take possession of all documentation, records, and files relating to the Collateral wherever they may be found, or require the Borrower to assemble such documentation, records and files and make them available to the Lender at a place designated by the Agent which is reasonably convenient to the Borrower and the Agent. 9 5.6 (a) No remedy conferred upon or reserved to the Agent or Lenders hereunder is or shall be deemed to be exclusive of any other available remedy or remedies. Each such remedy shall be distinct, separate and cumulative, shall not be deemed to be inconsistent with or in exclusion of any other available remedy, may be exercised in the discretion of the Lenders at any time (provided that it is not the intention of the parties hereto to waive any applicable statute of limitations as in effect from time to time), in any manner, and in any order, and shall be in addition to and separate and distinct from every other remedy given the Lenders hereunder, or any other security interest given to the Lenders, by the Borrower with respect to the Collateral, or now or hereafter existing in favor of the Lenders, at law or in equity or by statute. Without limiting the generality of the foregoing, the Lenders shall have the right to exercise any available remedy to recover any amount due and payable hereunder without regard to whether any other amount is due and payable, and without prejudice to the Lenders to exercise any available remedy for other Events of Default existing at the time the earlier action was commenced. Lenders shall, however, be under no duty or obligation whatsoever to take any action to preserve any rights of or against any other parties in connection with the Collateral or to take any action to protect or preserve the Collateral or any rights of the Borrower therein, or to make collections or enforce payment thereon, or to participate in any foreclosure or other proceeding in connection therewith. (b) Any delay, omission or failure by the Lenders to insist upon the strict performance by the Borrower of any of the covenants, conditions and agreements herein set forth or to exercise any right or remedy available to it upon the occurrence of a default in the payment of the Obligations, shall not impair any such right or remedy or be considered or taken as a waiver or relinquishment for the future right to insist upon and to enforce, by injunction or other appropriate legal or equitable remedy, strict compliance by the Borrower with all of the covenants, conditions and agreements, under the Loan Documents or otherwise, or of the right to exercise any such rights or remedies if such default by the Borrower be continued or repeated. 5.7 Upon the occurrence and during the continuance of an Event of Default, at the option of the Agent, Borrower's right to make collections on and receive proceeds of the Collateral and to use or dispose of such collections and proceeds shall terminate, and any and all proceeds and collections then held or thereafter received on or on account of the Collateral will be held or received by Borrower in trust for the Lenders and immediately delivered to the Agent. 5.8 Appointment of Agent. The Lenders hereby appoint Cumberland Associates LLC ("Cumberland") to serve, at the expense of the Borrower, as the Agent to act on behalf of the Lenders hereunder, and Cumberland hereby accepts such appointment; provided, however, that Cumberland shall have the right, in its sole discretion, to resign from serving as Agent and to appoint a successor Agent at any time or from time to time to act on behalf of all of the Lenders at the Borrower's expense.
