If the CD&R Investor beneficially owns less than 5% of the outstanding shares of common stock, the CD&R Investor will no longer be entitled to designate any designees for nomination by the board of directors.
With respect to any vacancy of a CD&R-designated director, the CD&R Investor has the right to designate a new director for election by a majority of the remaining directors then in office.
The CD&R Stockholder Agreement provides that a CD&R Designee will serve as the Chairman of our board of directors as long as the CD&R Investor beneficially owns at least 25% of the outstanding shares of our common stock.
The CD&R Stockholder Agreement also grants to the CD&R Investor certain other rights, including specified information and access rights.
