Receiver Appointed by the Secured Party

     Upon the occurrence of an Event of Default that is continuing, the Secured Party may appoint or reappoint by instrument in writing, any Person, except an officer or an employee of the Secured Party, to be a Receiver of the Mortgaged Property or any part thereof (including any interest, income or profits therefrom) and may remove any Receiver so appointed and appoint another in his stead. Any such Receiver shall, so far as concerns responsibility for his acts, be deemed the agent of the Corporation and not the Secured Party, and the Secured Party shall not be in any way responsible for any misconduct, negligence, or nonfeasance on the part of any such Receiver, his servants, agents or employees. The Secured Party may from time to time fix the Receiver’s remuneration. Subject to the provisions of the instrument appointing him, any such Receiver shall have power to take possession of the Mortgaged Property or any part thereof, to preserve its value, to carry on or concur in carrying on, or cease the carrying on, all or any part of the business of the Corporation and to sell, lease or otherwise dispose of or concur in selling, leasing or otherwise disposing of the Mortgaged Property or any part thereof (in its existing condition or after any repair, processing or preparation for disposition) in such manner, at such time or times and place or places, for such consideration and upon such terms and conditions as to the Receiver may seem reasonable including terms for deferred payment, upset, reserve bid or price.

     The Receiver may seize, collect, realize, maintain, dispose of, enforce, repair, replace, protect, preserve, substitute, prepare, process, release to third parties or otherwise deal with (and exercise the Corporation’s rights in) any Mortgaged Property in such manner, upon such terms and conditions and at such time as it deems advisable without notice to the Corporation, including:

	(e)		to perform the obligations of the Corporation hereunder and under any of the other Transaction Documents.

     To facilitate the foregoing powers, any such Receiver may, to the exclusion of all others, including the Corporation, enter upon, use and occupy all lands and premises owned or occupied by the Corporation wherein the Mortgaged Property or any part thereof may be situate, maintain the Mortgaged Property upon such premises, borrow Money on a secured or unsecured basis and use the Mortgaged Property directly in carrying on the Corporation’s business or as security for loans or advances or other credit to enable him to carry on the Corporation’s business or otherwise, as such Receiver shall, in his discretion, determine. Except as may be otherwise directed by the Secured Party, all amounts received from time to time by such Receiver in carrying out his appointment shall be received in trust for and paid over to the Secured Party. Every such Receiver may, in the discretion of the Secured Party, be vested with all or any of the rights and powers of the Secured Party. The Secured Party may, either directly or through its agents or nominees, exercise any or all of the powers and rights which could be available to a Receiver appointed pursuant to the foregoing.

     Upon the occurrence of an Event of Default the Secured Party or any Receiver may commence and proceed with any actions or judicial proceedings seeking such legal and/or equitable remedies as the Secured Party or Receiver deems advisable to protect and enforce its rights hereunder and in the Mortgaged Property, and may settle or adjust disputes and claims directly with debtors of the Corporation for amounts and on terms that the Secured Party considers advisable.

Receiver Appointed by the Court

The Corporation hereby authorizes any such consultant or monitor so appointed to enter onto the business premises of the Corporation and any other premises in which the Corporation is entitled to enter onto, and to inspect any of the Corporation’s books, records, information systems or property for such purposes, and the Corporation shall make available its senior officers and employees to assist such consultant or monitor in performing its duties. The reasonable costs and expenses of such consultant shall be for the account of the Corporation and shall be payable by the Corporation to the Secured Party on demand and shall bear interest at the Interest Rate, calculated from the date incurred by the Secured Party to the date paid by the Corporation and such amounts and such interest shall be secured by the Security.

The Corporation may designate any part of the Indebtedness to be satisfied by the retention of particular Mortgaged Property which the Secured Party considers, acting reasonably, to have a net realizable value approximating the amount of the designated part of the Indebtedness, in which case only the designated part of the Indebtedness will be deemed to be satisfied by the retention of the particular Mortgaged Property.

9.7

Remedies under the PPSA

No delay or omission of the Secured Party in the exercise of any right, power or remedy accruing upon any Event of Default shall impair any such right, power or remedy or shall be construed to be a waiver of any such Event of Default or an acquiescence therein. Every right, power and remedy given hereunder to the Secured Party or under Applicable Law may be exercised from time to time and as often as may be deemed expedient by the Secured Party.
