(g) Section 3(a) of the Rights Agreement shall be amended by replacing the term “Grandfathered Shareholders” with the term “Grandfathered Stockholders” in the sentence thereof.

(h) Section 3(a) of the Rights Agreement shall be further amended by adding the following two sentences at the end of this section:

“For the avoidance of doubt, because the transactions specifically contemplated by the Cornerstone Agreement, the Fairholme Agreement, the Pershing Agreement and the Warrant Agreement shall not result in a Shares Acquisition Date, neither (a) the acquisition of the Cornerstone Warrants, Pershing Warrants or Fairholme Warrants by the REP Holder, the Pershing Holders or the Fairholme Holders, (b) the acquisition of Common Shares through the exercise of the Cornerstone Warrants, Pershing Warrants or Fairholme Warrants by the REP Holder, any of the Pershing Holders or any of the Fairholme Holders, respectively, nor (c) the acquisition of up to an additional 2.5% of the issued and outstanding Common Shares by the Brookfield Holders, the acquisition of up to 0.714% of the issued and outstanding Common Shares by the Pershing Holders, nor the acquisition of up to an additional 1.786% of the issued and outstanding Common Shares by the Fairholme Holders, shall result in a Distribution Date.
