Annual Registration as a Public Offering. If an Annual Registration prior to the seventh anniversary of the

If an Annual Registration on or after the seventh anniversary of the IPO Date involves a Public Offering and the managing underwriter advises Lazard Ltd that, in its view, the number of shares of Common Stock requested to be included in such Public Offering exceeds the largest number of shares that can be sold within the price range (or 10% below the end of such range) that was included in the “red herring” registration statement for such Public Offering (provided that the Board of Directors of LAZ-MD shall not have objected to such price range prior to the filing of such red herring registration statement after notice thereof), the number of shares of Common Stock included in such Public Offering shall be reduced to such largest number of shares. In the event that the number of shares of Common Stock requested to be included in such Public Offering is reduced in accordance with this Section 4.1(b), Lazard Ltd shall include in such Public Offering, in the priority listed below, up to the applicable maximum number of shares to be included in such Public Offering as determined in the immediately preceding two sentences:
