Email from Scott A. McGregor to NetLogic Microsystems employees on September 12, 2011

Dear NetLogic Microsystems Employees:

By now you’ve seen Ron’s email announcing today’s important and exciting news. Let me be the first to welcome you to the Broadcom team. As you read in Ron’s email, we will be hosting two Town Hall meetings today to talk about how Broadcom and NetLogic Microsystems fit together and the path forward. We hope you will be able to participate in one of the meetings — a live meeting in Santa Clara and a live webcast for India, Asia and other geographies.

NetLogic Microsystems and Broadcom are similar on many fronts. We are both aggressive, energetic companies filled with the very best engineers and innovators. We both possess world-class technology and strong IP portfolios. And, we have both attracted exceptional customers.

We believe this deal will provide great value to customers, partners, shareholders and, most importantly, you. In the coming days, our team will be sharing more information about our business, entrepreneurial cultural and excellent benefits program.

Our guiding principle is simple: give engineers a complex problem, give them the tools they need, and get out of their way. With Broadcom’s resources, NetLogic Microsystems will be able to scale rapidly and accelerate the time to market. We are particularly excited about NetLogic Microsystems’ industry-leading multi-core processors, knowledge-based processors, digital front-end (DFE) processors and 10/40/100G PHYs. Together, we will be able to deliver a true end-to-end solution for a broad range of customers.

We anticipate the deal will close in the first half of 2012, subject to regulatory clearance and NetLogic Microsystems stockholder approval. A six-to-nine month closing seems long, but we have to work with authorities in the U.S and other countries.

After closing, NetLogic Microsystems employees will join our Infrastructure & Networking Group, led by Rajiv Ramaswami, executive vice president and general manager. Ron will become a senior vice president and an important member of Rajiv’s leadership team.

Know that everyone at Broadcom is enthusiastic about the deal and is looking forward to the day when you will officially join the team.

Scott McGregor
CEO, Broadcom
