To All Broadcom Employees:

This afternoon we sent a letter to Qualcomm stockholders reiterating our support for a combination of Broadcom and Qualcomm, asking Qualcomm stockholders to vote for the 11 independent directors we nominated in December. A copy of the press release we issued is attached.

The Qualcomm Annual Meeting is scheduled for March 6. Leading up to the meeting, we will be sending additional communications to Qualcomm stockholders, asking them to vote for the independent director nominees we have put forth to send a message to the Qualcomm Board that they should immediately engage with us regarding our compelling proposal.

Importantly, today’s announcement has no impact on our day-to-day operations – it is business as usual at Broadcom.

As this news is likely to result in continued media interest, it is important that the Company speak with one voice. If you receive inquiries from outside parties, please forward them to Ashish Saran at 408-433-4557 or ashish.saran@broadcom.com.

We will continue to keep you posted as we have updates to share. In the meantime, I thank you for your continued commitment to Broadcom. As we enter the New Year, we have many opportunities ahead and I am excited about what we will accomplish together.

Regards,

Hock Tan
