Company wishes to withdraw the Registration Statement because: the Registration Statement lacked required financial statements of a significant acquired business; subsequent to the effectiveness of the Registration Statement, Company became a domestic issuer; and the Registration Statement hasn’t been used for more than a year from effectiveness.
