Matters

Mr. Isajiw's representations include:

Complex Commercial and Securities Litigation

Darwin Deason, Xerox’s third-largest shareholder, in a successful action to stop Fuji from acquiring control of Xerox in a proposed $6.1 billion Xerox-Fuji merger. Following a two-day evidentiary hearing in New York Supreme Court, the court preliminarily enjoined the transaction and, for the first time under New York law, the court also allowed Xerox shareholders to nominate new director candidates even though the company’s notice deadline had passed.

Deutsche Bank Securities Inc., in connection with defeating a New York state court breach of contract action alleging the improper refusal to close on a $150 million real estate loan due to lack of interest in the CMBS market.

A leading global alternative asset manager and lender, as administrative agent, in connection with successfully securing both a temporary restraining order (TRO) and a preliminary injunction preventing the borrowers and guarantors of debt obligations in excess of $158 million from interfering with the firm’s exercise of lender rights to replace management and organize an orderly sale of borrower assets to repay the defaulted debts.
