        entered         into a cooperation agreement with the Issuer (the &#8220;<U>Cooperation Agreement</U>&#8221;). Pursuant to
        the Cooperation Agreement,         among other things, the parties agreed that the Issuer would expand its Board of
        Directors         (the &#8220;<U>Board</U>&#8221;) from         nine to eleven members and add two new members to the Board
        designated by Water         Asset Management. The two Water Asset Management         designees are expected to be named by
        the end of May 2018 and join         the Board immediately. All eleven members of the Board will         be subject to a
        vote         of the Issuer&#8217;s stockholders         at the Issuer&#8217;s 2018 annual meeting of stockholders. The two
        Water              Asset Management designees will qualify as         independent directors under the applicable
        independence         rules of the         Nasdaq Global Market         and at least one Water         Asset Management
        designee will be assigned         to serve on each of         the committees of the Board. Once the two         Water Asset
        Management designees are         named, Water Asset Management         will continue to have the right to designate up to
        two         directors             to the         Board for as long as it maintains certain         ownership levels in the
