In order, however, to provide Acquisition the full realization and value of every Purchased Contract Right of the character hereinbefore described, ATI at and after the Closing will, at the request and under the direction of Acquisition and in the name of ATI or otherwise as Acquisition shall specify, take or cause to be taken all such action (including without limitation the appointment of Acquisition as attorney-in-fact for ATI, but with powers limited to the specific purposes contemplated hereby) and do or cause to be done all such things as shall in the reasonable opinion of Acquisition be necessary or proper to (a) assure that the rights of ATI under all Purchased Contract Rights shall be preserved for the benefit of Acquisition, and (b) facilitate receipt by Acquisition of the consideration to which ATI would otherwise be entitled in and under all Purchased Contract Rights, which consideration shall be held for the benefit of, and shall be delivered to, Acquisition.
