together with necessary documents, with the cooperation of the Transferor. The Exhibit attachedhereto shows the same instruction as explained in the email.

Even in such cases, as long as the transfer of the Bankruptcy Claim was made before thecommencement of the Civil Rehabilitation Proceedings, the Transferee may file a proof of claim in
the Civil Rehabilitation Proceedings by following the instructions in the Exhibit attached hereto.

Finally, please note that the instructions in the Exhibit attached hereto only apply to the transfer ofthe Bankruptcy Claim before the commencement of the Civil Rehabilitation Proceedings. The
