SAN FRANCISCO — Latham & Watkins represented computer hardware manufacturer Mellanox Technologies Ltd. in its merger agreement with EZchip Semiconductor Ltd., valued at about $811 million. Per terms of the deal, Mellanox will purchase 100 percent of EZchip's outstanding ordinary shares for a cash purchase price of $25.50 per share. The deal is expected to close in the first quarter of 2016.

Menlo Park-based partners Alan Mendelson and Mark Roeder led the Latham team, with the help of associates Chad Rolston, Brian Paulson and Benjamin Liss. Mendelson could not be reached for comment, and Roeder did not immediately return a call seeking comment.

The firm has been representing Mellanox for at least 13 years. In 2002, Latham helped the company raise $56 million in its third round of fundraising as a private company. Mendelson worked on that deal, too.
