Group; (ii) the voting limitations set forth in the Company's charter do not
apply to the RAH Group; (iii) any further acquisition of Common Stock by the RAH
Group would not trigger the three-year moratorium



set forth in the BCL or the voting limitations set forth in the Company's

Common Stock that is the subject of the T5 Option.
