Sullivan & Cromwell is representing German drugs and crop chemicals group Bayer AG in its offer to buy U.S. seeds company Monsanto for $62 billion in cash. Allen & Overy is advising Bayer on the financing of the transaction, while Wachtell Lipton Rosen & Katz is acting for Monsanto.

The unsolicited proposal would be the largest all-cash takeover on record, according to Thomson Reuters data, just ahead of InBev’s $60.4 billion offer for Anheuser-Busch in June 2008.

The S&C team on the transaction includes corporate partners Matthew G. Hurd and Eric M. Krautheimer; and antitrust partners Steven L. Holley and Juan Rodriguez. The A&O team advising includes banking and finance partners Neil Weiand, Thomas Neubaum, Nicholas Clark and George Link; corporate partners Hans Diekmann and Stephen Mathews; capital markets partner Oliver Seiler; and tax partner Marcus Helios.

Luthra & Luthra (L&L) is representing Bayer on the Indian law aspects of the acquisition.

The L&L team was led by Mohit Saraf and comprised of Sundeep Dudeja and Amit Shetye advising on general corporate aspects, and G.R. Bhatia, Abdullah Hussain and Kanika Chaudhary Nayar advising on competition law.
