Any share certificate that, immediately prior to the Effective Time, represented Class A common shares of the Corporation as a Bermuda exempted company shall, from and after the Effective Time, automatically and without the necessity of presenting the same for exchange, represent the same number of shares of Common Stock.

SEVENTH. Elections of directors need not be by written ballot except and to the extent provided in the by-laws of the Corporation.

EIGHTH. The number of directors of the Corporation shall be fixed from time to time pursuant to the by-laws of the Corporation. The directors of the Corporation shall be divided into three classes, as nearly equal in number as reasonably possible, as determined by the Board, with the initial term of office of the first class of such directors to expire at the first annual meeting of stockholders following the Effective Time, the initial term of office of the second class of such directors to expire at the second annual meeting of stockholders following the Effective Time and the initial term of office of the third class of such directors to expire at the third annual meeting of stockholders following the Effective Time, with each class of directors to hold office until their successors have been duly elected and qualified. At each annual meeting of stockholders beginning with the first annual meeting of stockholders following the effectiveness of this Certificate of Incorporation, directors elected to succeed the directors whose terms expire at such annual meeting shall be elected to hold office for a term to expire at the third succeeding annual general meeting of stockholders after their appointment and until their successors have been duly elected and qualified. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain or attain a number of directors in each class as nearly equal as reasonably possible, but no decrease in the number of directors may shorten the term of any incumbent director. No director may be removed except for cause. Cause for removal shall be deemed to exist only if the director whose removal is proposed has been convicted of a felony by a court of competent jurisdiction or has been adjudged by a court of competent jurisdiction to be liable for gross negligence or misconduct in the performance of such director’s duty to the Corporation and such adjudication is no longer subject to direct appeal.

NINTH. Any action required or permitted to be taken by the holders of any class or series of stock of the Corporation, except in the case of the removal of an auditor or a director, which may not be taken by written consent or consents, may be taken by written consent or consents but only if such consent or consents are signed by all holders of the class or series of stock entitled to vote on such action.

TENTH.

(a) A director or officer of the Corporation shall not be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except to the extent that such exemption from liability or limitation thereof is not permitted under the DGCL as currently in effect or as the same may hereafter be amended. This article TENTH includes any actions taken or omitted as a director or officer of the Corporation (whether taken or omitted prior to the Effective Time, in connection with the discontinuance of the Corporation in Bermuda or the continuance of the Corporation in the State of Delaware or otherwise).

(b) To the fullest extent permitted by applicable law, the Corporation is authorized to provide indemnification of (and advancement of expenses to) directors, officers and agents of the Corporation (and any other persons to which applicable law permits the Corporation to provide indemnification) through by-laws, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise.

(c) Any amendment, modification or repeal of this Article TENTH shall only be prospective and shall not adversely affect any right or protection or increase the liability of any officer or director under this Article TENTH as in effect at the time of the alleged occurrence of any act or omission to act giving rise to liability or indemnification.

ELEVENTH. Clause (c) of Article FOURTH and Articles EIGHTH, TENTH and ELEVENTH may not be amended, modified or repealed except by the affirmative vote of the holders of not less than 66^2/₃% of the voting power of all outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, considered for purposes hereof as a single class.
