Section 8 - Other Events Item 8.01 Other Events. Bank of America, N.A. as successor by merger to LaSalle Bank N.A. acts as trustee for the issuing entity. On November 25, 2009, Bank of America, N.A. (BANA) was named as a defendant in two related lawsuits filed in the U.S. District Court for the Southern District of New York. In BNP Paribas Mortgage Corporation v. Bank of America, N.A. and Deutsche Bank, AG v. Bank of America, N.A., plaintiffs assert breach of contract, negligence, and indemnification claims in connection with BANA's roles as, among other things, collateral agent, custodian, and indenture trustee of Ocala Funding, LLC (Ocala). Ocala was a mortgage warehousing facility that provided funding to Taylor, Bean & Whitaker Mortgage Corp. (TBW) by issuing commercial paper and term securities backed by mortgage loans originated by TBW. Plaintiffs claim that they purchased in excess of $1.6 billion in securities issued by Ocala and that BANA allegedly failed, among other things, to protect the collateral backing plaintiffs' securities. Plaintiffs seek unspecified compensatory damages, among other relief.
