  the assumption of approximately $10.4 million in obligations, which will be
  converted to APS preferred stock with a 3% dividend and a cash redemption
  requirement payable evenly over ten years. The merger remains subject to
  approval by the Texas Department of Insurance, necessary filings with the SEC,
  and the approval of the shareholders of APS and subscriber-policyholders of
