 below, this summary does not discuss applicable
income tax reporting requirements. This summary does not describe any state, local or non-U.S. tax law considerations, or any aspect of U.S. federal tax law other than income taxation (e.g., estate or gift tax
or the Medicare contribution tax). U.S. Holders (as defined below) should consult their tax advisers regarding such matters.

No legal
opinion from U.S. legal counsel or ruling from the IRS has been requested, or will be obtained, regarding the U.S. federal income tax consequences to U.S. Holders (as defined below) of the Arrangement. This summary is not binding on the IRS, and the
IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to different interpretations, the IRS and U.S.
courts could disagree with one or more of the positions taken in this summary.

As used in this summary, a “U.S. Holder” is a
beneficial owner of the Common Shares who, for U.S. federal income tax purposes, is (i) a citizen or individual resident of the United States, (ii) a corporation (or other entity that is classified as a corporation for U.S. federal income
tax purposes) that is created or organized in or under the laws of the United States, any State thereof or the District of Columbia, (iii) an estate whose income is subject to U.S. federal income tax regardless of its source, or (iv) a
trust if (A) a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized to control all substantial decisions of the trust, or (B) the trust has a valid election in effect
to be treated as a U.S. person for U.S. federal income tax purposes.

If an entity or arrangement that is classified as a partnership for
U.S. federal income tax purposes holds Common Shares, the U.S. federal income tax treatment of a partner will depend on the status of the partner and the activities of the partnership. Partnerships holding Common Shares and partners in such
partnerships should consult their tax advisers as to the particular U.S. federal income tax considerations relating to the Arrangement.

For purposes of this summary, a “non-U.S. holder” is a beneficial owner of Common Shares,
other than a partnership or other
