Hanks, Jr., at the United States District Court, Southern District of Texas, Houston Division, Bob Casey United States Courthouse, 515 Rusk Street, Houston, TX  77002, for the purpose of determining, among other things, whether: (i) the proposed Settlement should be approved by the Court as fair, reasonable, and adequate; (ii) the proposed Plan of Allocation for distribution of the Settlement proceeds is fair, reasonable, and adequate and therefore should be approved; and (iii) the application of Class Counsel for the payment of attorneys' fees and expenses from the Settlement Fund, including interest earned thereon, and awards to Class Plaintiffs pursuant to 15 U.S.C. §78u-4(a)(4), should be granted.
