(a)        SPE and Hansen intend that the assignment from Hansen to SPE underSection 2.1 is and shall constitute an absolute and unconditional sale to SPE from Hansen of all of Hansen’s right, title and interest in and to the Assigned Interest, and not a loan.

(b)        In the event that, notwithstanding the intent of SPE and Hansen to the contrary, the assignment under Section 2.1 is for any reason deemed by acourt of competent jurisdiction not to constitute an absolute and unconditional sale of the Assigned Interest to Purchaser, (i) SPE and Hansen agree that such assignment shall be deemed to constitute the grant of a valid and continuing securityinterest by Hansen to SPE in all right, title and interest of Hansen in and to the Assigned Interest and (i) Hansen covenants and agrees (A) not to permit or suffer to exist any claims, liens or encumbrances upon the Assigned Interest,other than by, through or under SPE or its successors or assigns, and (B) not to sell, mortgage, pledge or otherwise hypothecate the Assigned Interest. This Agreement shall constitute a security agreement under applicable law if the assignmentunder Section 2.1 is deemed not to constitute a sale. Hansen hereby authorizes SPE to file any and all financing statements necessary to perfect the grant of such security interest under the applicable Uniform Commercial Code or to maintainperfection thereof; *provided, however, that* prior to making any such filing, SPE shall submit a draft of such filing to Hansen for its review and approval. No such filing or other action under or pursuant to this Section 2.3(b) shall beconstrued to prejudice the intent of SPE and Hansen that the assignment pursuant to Section 2.1 constitute an absolute and unconditional sale.
