(v)           if, upon conclusion of the Auction, and consistent with the terms of these bidding procedures, Purchaser’s final bid matches or is greater than the highest bid made by a Qualified Overbidder, the Bankruptcy Court shall approve this Agreement and authorize the Company to sell the Assets to Purchaser, and the amount of Purchaser’s final bid (less the amount of the Expense Reimbursement) shall constitute the Purchase Price under this Agreement; and

(vi)           Company may, with Bankruptcy Court approval, elect to deem Purchaser’s final bid to be the highest bid, notwithstanding the receipt of an apparently higher bid from another Overbidder, if the Company reasonably concludes that the Overbidder may not be able to close, or for any other reason.

(g)           Purchaser has standing and is deemed to be a party in interest with standing to be heard on any motion, hearing or other matter related to this Agreement or any Overbid, or other sale of assets subject to this Agreement.

10.7.        Invalidity

Each of the provisions contained in this Agreement is distinct and severable and a determination of illegality, invalidity or unenforceability of any such provision or part hereof by a court of competent jurisdiction shall not affect the validity or enforceability of any other provision hereof, unless as a result of such determination this Agreement would fail in its essential purposes.
