Identification of the Audit Committee.

Information regarding the Audit Committee of Manulifes Board of Directors is set forth under the heading Audit Committee - Composition of the Audit
Committee in 2015 in the Companys Annual Information Form (AIF) dated February 18, 2016 for the fiscal year ended December 31, 2015, filed as Exhibit 99.3 to this Annual Report on
Form 40-F.

Independence of Directors.

A majority of the directors and all members of the Boards standing committees must be independent so that the Board operates independently of management.

A director is independent if he or she does not have a direct or indirect relationship with the Company that could reasonably be expected to interfere
with the directors ability to exercise independent judgment. The Company has established an independence policy for the Board which is consistent with applicable legal and regulatory requirements, including those established under Canadian and
U.S. securities law, the Insurance Companies Act (Canada) and the rules of the New York Stock Exchange. The independence policy is available on our website (www.manulife.com).

Each year the Board, with the assistance of the Corporate Governance and Nominating Committee, reviews the independence of each director and has determined
that 13 of the 14 director nominees are independent and that the members of the Audit Committee and the Management Resources and Compensation Committee meet the additional independence requirements for those committees. As CEO, Donald Guloien is not
independent.

Presiding Director at Meetings of Non-Management Directors.

The independent directors meet regularly with senior executives and have an opportunity to meet privately without management present during the closed session
held at the end of each Board and committee meeting. They may also use these sessions to meet privately with members of management or independent advisors.

In addition, the independent directors meet at least once each year in a closed session without the CEO present to review the performance and approve the
compensation of the CEO, to review the Boards effectiveness assessments and to approve the Boards objectives for the following year. In 2015, one such meeting of the independent directors was held which was presided over by the Chairman
of the Board.

Communication with Non-Management Directors.

Shareholders wishing to contact non-management Directors of the Company may write to the Chairman of the Board, in care of the Corporate Secretary, at the head
office of the Company, 200 Bloor Street East, Toronto, Ontario, Canada, M4W 1E5.

Corporate Governance Guidelines.

The Companys governance practices are consistent in all material respects with the requirements of the Insurance Companies Act (Canada), the
corporate governance guidelines established by the Office of the Superintendent of Financial Institutions (Canada) and by the Canadian Securities Administrators, the New York Stock Exchange corporate governance rules for domestic issuers and the
applicable U.S. Securities and Exchange Commission rules and regulations. The Companys statement of corporate governance practices is posted on the corporate governance section of our website and is available at:
http://manulife.com/public/about/index/0,,lang=en&navId=610005,00.html.

Board Committee Charters.

The Board has established four standing committees to assist it in fulfilling its mandate: Corporate Governance and Nominating Committee, Audit Committee, Risk
Committee and Management Resources and Compensation Committee.

All of the members of the standing committees are independent. Each committee reviews and,
as necessary, updates its charter every year and monitors compliance with its charter on a regular basis throughout the year. Each committee chair reports to the Board on the committees deliberations and any recommendations that require Board
approval.

The committee charters and the position description for each committee chair are posted on the corporate governance section of our website and
are available at: http://manulife.com/public/about/index/0,,lang=en&navId=610011,00.html.
