The beneficiaries of The Happy Family Trust are Mr. Zheng, Mr. Zheng's wife (namely, Li, Sha), and Mr. Zheng's two children (namely, Zheng, Ruida and Zheng, Ruixi). Therefore, pursuant to Section 13(d) of the Act and the rules promulgated thereunder, Audrey &amp; Aaron Holdings, Wisdom Sail, and Mr. Zheng may each be deemed to beneficially own the 2,651,261 shares of Common Stock held by Ahwanova.</footnote>
