thereof, as applicable, and such other documents and information as it deems appropriate to make its own credit analysis and decision to enter into this Amendment and to purchase its Assigned Interest, (vi) it has, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Amendment and to assume its Assigned Interest and (vii) attached hereto is the documentation required to be delivered by it pursuant to the terms of the Credit Agreement, if any, duly completed and executed by such Assignee; and (b) agrees that (i) it will, independently and without reliance upon the Agent, any Assignor or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Credit Agreement, and (ii) it will perform in accordance with their terms all of the obligations which by the terms of the Credit Agreement are required to be performed by it as a Lender.
