Item 5.07 Submission of Matters to a Vote of Security Holders

A Special Meeting of the Stockholders of Zenith National Insurance Corp. (the “Registrant”) was held on April 29, 2010. Two matters were presented to a vote of the stockholders.

The first matter was to consider and vote on a proposal to adopt the Agreement and Plan of Merger, dated as of February 17, 2010 (the “Merger Agreement”), among Fairfax Financial Holdings Limited, a Canadian corporation (“Fairfax”), Fairfax Investments II USA Corp., a Delaware corporation and an indirect wholly owned subsidiary of Fairfax, and the Registrant.

Adoption of the Merger Agreement required that stockholders of the Registrant representing at least a majority of the outstanding shares of the Registrant’s common stock vote in favor of the proposal. The final vote on this first matter was as follows:

Votes For		Votes Against		Abstentions
28,828,698		76,382		233,512

Since the favorable votes constituted 76% of the 37,930,463 outstanding shares of the Registrant’s common stock, the Merger Agreement was adopted by the stockholders of the Registrant.

The second matter was to consider and vote on a proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies. Because the proposal to adopt the Merger Agreement was approved by the Registrant’s stockholders, this matter became moot. The final vote on the second matter was as follows:

Votes For		Votes Against		Abstentions
27,033,933		1,858,527		246,132

Brokers did not have discretionary voting authority on either matter and, as a result, there were no broker non-votes. No votes were withheld for either matter.

SIGNATURE

Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
