LEGAL*52823942.10

(xi)

by instrument in writing, to appoint any Person or Persons (whether an officer or officers of the Lender or not) as a Receiver (as defined herein to include a receiver and manager) of the Secured Property and to remove any Receiver so appointed and appoint another or others in its stead.

(a)Without limiting the generality of the foregoing in connection with the exercise of remedies under this ARTICLE 6, it shall be lawful for the Lender:

(i)to make any sale, lease or other disposition of the Secured Property either for cash or upon credit or partly for one and partly for the other upon such

LEGAL*52823942.10

conditions as to terms of payment as it in its absolute discretion may deem proper;

The Corporation shall be accountable for any deficiency and the Lender shall be accountable for any surplus. The Lender may deliver to the purchaser or purchasers of the Secured Property or any part thereof good and sufficient conveyances or deeds for the same free and clear of any claim by the Corporation or any Guarantor. The purchaser or lessee receiving any disposition of the Secured Property or any part thereof need not inquire whether default under this Debenture has actually occurred but may as to this and all other matters rely upon a statutory declaration of an officer of the Lender, which declaration shall be conclusive evidence as between the Corporation or Guarantor and any such purchaser or lessee, and the purchaser or lessee need not look to the application of the purchase money, rent or other consideration given upon such sale, lease or other disposition, which shall not be affected by any irregularity of any nature or kind relating to the crystallizing or enforcing of the security hereof or the taking of possession of the Secured Property or the sale, lease or other disposition thereof.

Any Receiver appointed pursuant to the Security Documents shall have the power without legal process:

(a)

to take possession of the Secured Property or any part thereof wherever the same may be found;

(b)

to carry on the business of the Corporation or Guarantor or any part thereof in the name of the Corporation, a Guarantor or of the Receiver; and

(c)

to exercise on behalf of the Lender all of the rights and remedies herein granted to the Lender,

and without in any way limiting the foregoing the Receiver shall have all the powers of a receiver appointed by a court of competent jurisdiction. Any Receiver appointed by the Lender shall act as agent for the Lender for the purposes of taking possession of the Secured Property, but otherwise and for all other purposes (except as provided below), as agent for the Corporation or any Guarantor. The Receiver may sell, lease, or otherwise dispose of Secured Property as agent for the Corporation, Guarantors or as agent for the Lender, as the Lender may determine in

LEGAL*52823942.10

its discretion. The Corporation and each Guarantor agrees to ratify and confirm all actions of the Receiver acting as agent for the Corporation and any Guarantor, and to release and indemnify the Receiver in respect of all such actions. The Lender, in appointing or refraining from appointing any Receiver shall not incur liability to the Receiver, the Corporation, a Guarantor or otherwise and shall not be responsible for any misconduct or negligence of such Receiver or for any loss resulting therefrom.

(ii) assume control of any proceeds arising from the Secured Property.

Dealing with the Secured Property

The Lender shall not be obliged to exhaust its recourse against the Corporation, the Guarantors or any other person or persons or against any other security it may hold in respect of the Obligations before realizing upon or otherwise dealing with the Secured Property in such manner as the Lender may consider desirable. The Lender may grant extensions or other indulgences, take and give up securities, accept compositions, grant releases and discharges and otherwise deal with the Corporation, any Guarantor and with other parties, sureties or securities as the Lender may see fit without prejudice to the Obligations or the rights of the Lender in respect of the Secured Property. The Lender shall not be (i) liable or accountable for any failure to collect, realize or obtain payment in respect of the Secured Property; (ii) bound to institute proceedings for the purpose of collecting, enforcing, realizing or obtaining payment of the Secured Property or for the purpose of preserving any rights of the Lender, the Corporation, any Guarantor or any other parties in respect thereof; (iii) responsible for any loss occasioned by any sale or other dealing with the Secured Property or by the retention of or failure to sell or otherwise deal therewith; or (iv) bound to protect the Secured Property from depreciating in value or becoming worthless.

LEGAL*52823942.10

7.2Other Security

7.3No Merger or Novation

Neither the taking of any judgment nor the exercise of any power of seizure or sale shall operate to extinguish the liability of the Corporation to pay the moneys hereby secured nor shall the same operate as a merger of any covenant herein contained or of any other Obligation, nor shall the acceptance of any payment or other security constitute or create any novation.

LEGAL*52823942.10
