Q1: What are the methods of filing Exchange-Related Bankruptcy Claims?
A: The bankruptcy trustee has created a system (the “System”) that enables Users to file
Exchange-Related Bankruptcy Claims through a website. The following two methods of filing
Exchange-Related Bankruptcy Claims are available:(1) you may file your bankruptcy claim using the System (the “Online Method”); or(2) you may file your bankruptcy claim by downloading the bankruptcy claim form that isprescribed by the Bankruptcy Trustee (“Exchange-Related Bankruptcy Claim Form (Form(1)-1)”), completing the form on your computer and mailing the completed form to MTGOX
Co., Ltd. Office of Bankruptcy Trustee (the “Offline Method”).

If a User wishes to file an Exchange-Related Bankruptcy Claim using the Online Method specified
in option (1) above, after logging in to the System, the User will be asked to select to either (i) filethe bankruptcy claim via Kraken’s system or (ii) file the bankruptcy claim via the System. It isnecessary to become a Kraken user in order to file an Exchange-Related Bankruptcy Claim via
Kraken’s system.
By becoming a Kraken user, it may be possible for Users to enjoy certain benefits such as the ability2

to receive bankruptcy distribution in Bitcoin (this matter has not yet been determined whether

Q2: What were the main reasons why the bankruptcy trustee created the System?
A: If the System were not created, Users throughout the world would have to file Exchange-Related
Bankruptcy Claims by completing the bankruptcy claim form designated by the bankruptcy trustee
and mailing the completed form to MTGOX Co., Ltd. Office of Bankruptcy Trustee (the “Offline
Method”).
The Tokyo District Court and the bankruptcy trustee believe that it would be extremely difficult forUsers throughout the world to smoothly file Exchange-Related Bankruptcy Claims in accordancewith the Japanese Bankruptcy Law and other laws and regulations, and that time and expense would
be required for Users to file their Exchange-Related Bankruptcy Claims.
Furthermore, if it were the case that Exchange-Related Bankruptcy Claims can only be filed using
the Offline Method, for example, because of the need of the many Users throughout the world, theTokyo District Court and the bankruptcy trustee to repeatedly send documents among them in thesebankruptcy proceedings, it would have resulted in the parties involved in the bankruptcy proceedings
having to spend a considerable amount of time and expense, making it difficult to conduct thesebankruptcy proceedings in a proper and smooth manner.
Accordingly, the Tokyo District Court and the bankruptcy trustee created the System for the purposeof conducting these bankruptcy proceedings in a proper and smooth manner for the interests of allparties involved in the bankruptcy proceedings, including Users and all other bankruptcy creditors.

will be conducted in a proper and smooth manner, and is in the interests of all concerned
parties, including Users. Therefore, the bankruptcy trustee requests you to cooperate by filingyour Exchange-Related Bankruptcy Claim using the Online Method.

trustee to make this confirmation, and the said Exchange-Related Bankruptcy Claim could be

the bankruptcy trustee will ask for each User’s final choice regarding whether Users wish to receive
distributions in Bitcoin. Please note that, even if a User responds to the survey stating that the User
