15.  Plaintiff brings this action on behalf of all individuals and entities who purchased  Helios common stock on the public market during the Class Period, and were damaged,  excluding the Company, the defendants and each of their immediate family members, legal  representatives, heirs, successors or assigns, and any entity in which any of the defendants have  or had a controlling interest (the “Class”).   17.  Plaintiff’s claims are typical of the claims of the members of the Class as all  members of the Class are similarly affected by the Defendants’ wrongful conduct in violation of  the federal securities laws complained of herein.    18.  Plaintiff has and will continue to fairly and adequately protect the interests of the  members of the Class and has retained counsel competent and experienced in class and securities  litigation. Plaintiff has no interests antagonistic to or in conflict with those of the other members  of the Class.   20.  A class action is superior to all other available methods for the fair and efficient  adjudication of this controversy since joinder of all members is impracticable. Furthermore, as  the damages suffered by individual Class members may be relatively small, the expense and  burden of individual litigation make it impossible for members of the Class to individually  redress the wrongs done to them. There will be no difficulty in the management of this action as  a class action.
