Notice Regarding Establishment of Third-Party Committee

TOKYO, JAPAN - December 15, 2016 - In order to address the issues announced in the disclosure dated December 5, 2016, titled "Notice Regarding Establishment of Third-Party Investigative Committee and Withdrawal of All Articles from Entire Curation Platform Services" (hereafter referred to as "this issue"), DeNA Co., Ltd. (DeNA) has decided, during the board meeting held on December 15, 2016, to establish a Third-Party Committee as follows.

Note: In the disclosure dated December 5, 2016 DeNA referred to this committee as the "Third-Party Investigative Committee," but the objective, as stated below, is not limited to investigation only. The name has therefore been changed to "Third-Party Committee."

1. Objective for the Third-Party Committee

Investigate the factual details of this issue and ascertain the cause (not only direct causes, but also general factors such as issues with corporate culture, compliance and organizational structure), as well as propose necessary improvements (hereafter referred to as "this investigation").

2. Formation of the Third-Party Committee

The committee members have been appointed based on a selection process primarily led by external board members.

• Committee Chair: Katsuya Natori, Attorney-at-law (Former Member of the Board at IBM Japan)
• Committee Member: Motoyoshi Nishikawa, Attorney-at-law (Former Managing Director and Member of the Board at Nippon Steel Corporation)
• Committee Member: Hisamichi Okamura, Attorney-at-law (Visiting Professor at the National Institute of Informatics)
• Committee Member: Mieko Okita, Attorney-at-law (Former prosecutor at the Special Investigation Department, Tokyo District Public Prosecutor's Office)

Note: The committee members were selected in accordance with the Japan Federation of Bar Associations' Guidelines for Third-Party Committees Relating to Corporate Scandals (Revised December 17, 2010). None of the members have a conflict of interest or any other factors that could impede the independence of this committee.

Katsuya Natori is the most appropriate choice to lead the Third-Party Committee given his high level of investigative skill as well as his deep knowledge and insight into compliance and corporate governance in companies, acquired through his vast experience over many years as in-house counsel and as a corporate executive. Further, all other committee members have been selected for having abilities suited to investigating and analyzing issues with characteristics such as this issue, and also proposing improvements, acquired through their experience and expertise. Background information on all committee members can be found at the end of this release.

In the disclosure dated December 5, 2016, we stated that this committee would include external board members; however, in order to completely ensure the objectivity and independence of this investigation, no external board members will be included in the committee.

3. Investigation Schedule and future plans

The period for this investigation by the Third-Party Committee is initially set to be 3 months. We will fully cooperate with the investigation of the Third-Party Committee. Once this investigation is completed, a report will be sent to the board of directors and we plan to make this report public as soon as possible.

We are aiming to become a company capable of providing internet services that are trusted by society, and will implement any necessary radical reform based on the committee report, including any measures against executives and employees.

4. Future outlook

Separately from this investigation, we will assess the future policies and plans for the curation platform business. At this moment, the outlook does not differ from what was disclosed on December.
