5.     The Pledgor hereby affirms the representations and warranties appearing in Section 4 of the Loan Agreement and such representations and warranties are incorporated by reference herein.

6.     Subject to applicable law, Plenus shall be entitled on its own behalf and on behalf of the Co-lenders to enforce the Floating Charge against the Pledgor, and the Collateral shall be subject to immediate foreclosure, at any time and without any further demand, immediately upon the occurrence of an Event of Acceleration, unless otherwise provided for in this Agreement or the Loan Agreement.

For purposes of this Agreement, the term M&A Transaction shall mean the consummation of (a) a transaction or a series of transactions for the sale or other disposition of all, or substantially all, of the assets or business of the Corporation, or (b) a transaction or a series of transactions, including, without limitation, a merger or consolidation, whereby, or as a result thereof, the Corporation’s shareholders immediately prior thereto, hold 50% or less of the voting power of the Corporation, the surviving entity or the new entity (as the case may be) or they will no longer have the power or the right to appoint more than fifty (50%) percent of the members of the board of directors of such entity.

No delay or omission to exercise any right, power, or remedy accruing to any party upon any breach or default under this Agreement, shall be deemed a waiver of such party’s rights or remedies with respect to such breach or any other breach or default theretofore or thereafter occurring. All remedies, either under this Agreement or by law or otherwise afforded to any of the parties, shall be cumulative and not alternative.
