The failure or waiver of performance under this Contribution Agreement by any Existing Owner or Seller, or on its behalf, does not excuse performance by any other Existing Owner or Seller. Nothing contained herein, no transactions contemplated hereby, and no action taken by any Existing Owner or Seller pursuant hereto, shall be deemed to constitute the Existing Owners and/or the Sellers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Existing Owners or the Sellers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. Each Existing Owner and each Seller shall be entitled to independently protect and enforce its rights, and it shall not be necessary for any other Existing Owner or Seller to be joined as an additional party in any proceeding for such purpose.
