The combined businesses currently have approximately 700 employees and achieved revenues of $217 million for the twelve months ended Sept. 30, 2010.

Mellanox currently anticipates that the transaction will be accretive to its fiscal 2011 non-GAAP earnings by $0.02 - $0.05 or more per share. With highly complementary products, markets, customers and strategies, Mellanox expects the proposed acquisition of Voltaire to enhance its market position as a leading provider of end-to-end connectivity solutions for servers and storage systems. The combination will also help Mellanox achieve meaningful revenue and cost synergies over time, with estimated, annualized cost synergies of at least $10 million by the end of 2012.

Mellanox's Board of Directors has indicated its intention to nominate Ronnie Kenneth, the chairman and CEO of Voltaire, to join its Board of Directors at Mellanox's Annual General Meeting of shareholders, which it currently anticipates will be held in May 2011. Mr. Kenneth has indicated his intention to join the Board of Directors of Mellanox.

Mellanox and Voltaire believe that employees represent one of their most important assets, and Mellanox looks forward to combining employees from both organizations under one unified management team. Mellanox expects to run the combined business from both companies' current offices located in Israel, the United States and around the world. Further, Mellanox intends to retain both companies' existing product lines and will converge such lines in future product generations to ensure continuity for customers and partners of both companies. Through this acquisition, Mellanox expects to achieve additional scale to permit it to operate as a larger, more successful and more profitable enterprise, thus increasing value for the combined company's shareholders and customers.

"The combination of Mellanox and Voltaire will create a leading provider of connectivity solutions for our customers by leveraging the complementary strengths of our companies. Together, we believe the combined company will be a stronger business partner and system solutions provider, delivering customers a comprehensive range of end-to-end connectivity solutions," said Eyal Waldman, president, chairman and CEO of Mellanox Technologies. "We welcome the great talent from Voltaire and look forward to completing the integration of our employees to create a superior combined company."

"We expect the combined company to offer our customers the financial strength of Mellanox, industry-leading solutions and world-class development teams that drive innovation and enhance market opportunities."

Mellanox believes that the Voltaire acquisition will strengthen its leadership position in providing end-to-end connectivity systems and will expand its software and product offerings in the growing worldwide datacenter server and storage markets it serves.
