Item 1.01 Entry into a Material Definitive Agreement

On November 4, 2011, Broadcom Corporation (“Broadcom”) entered into an Underwriting Agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC, as representatives of the several underwriters named therein (the “Underwriters”), pursuant to which Broadcom agreed to issue and sell to the Underwriters $500 million aggregate principal amount of 2.700% Senior Notes due 2018 (the “Notes”).

On November 9, 2011, Broadcom completed the offering of the Notes.

In connection with the closing of the Notes offering, Broadcom entered into the Second Supplemental Indenture, between Broadcom and Wilmington Trust, National Association, as successor by merger to Wilmington Trust FSB, as trustee (the “Trustee”), dated as of November 9, 2011 (the “Second Supplemental Indenture”), to the indenture, between Broadcom and the Trustee, dated as of November 1, 2010 (the “Base Indenture” and, together with the Second Supplemental Indenture, the “Indenture”).

The Notes mature on November 1, 2018 and accrue interest at a rate of 2.700% per annum, payable semiannually in arrears in cash on May 1 and November 1 of each year, beginning May 1, 2012.

The Notes are subject to a special mandatory redemption in the event Broadcom’s proposed acquisition of NetLogic Microsystems, Inc. (“NetLogic”) is not consummated on or prior to August 31, 2012, or if prior to August 31, 2012, the Agreement and Plan of Merger, dated as of September 11, 2011, by and among Broadcom, NetLogic and I&N Acquisition Corp., Broadcom’s wholly owned subsidiary, is terminated. In such an event, the Notes will be redeemed for cash at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to but excluding the special mandatory redemption date. Upon a change of control triggering event, each holder of the Notes will have the right to require Broadcom to purchase for cash all or a portion of such holder’s Notes at a purchase price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest. Broadcom may redeem the Notes, at any time in whole or from time to time in part, at a specified make-whole premium. The Indenture contains covenants limiting Broadcom’s ability to create certain liens, enter into sale and lease-back transactions, and consolidate or merge with or into, or convey, transfer or lease all or substantially all of Broadcom’s properties and assets to, another person, each subject to certain exceptions.

The Notes were offered and sold pursuant to Broadcom’s shelf-registration statement on Form S-3 (Registration No. 333-157088) under the Securities Act of 1933, as amended. Broadcom has filed with the Securities and Exchange Commission (the “SEC”) a prospectus supplement, dated November 4, 2011, together with the accompanying prospectus, dated November 4, 2011, relating to the offer and sale of the Notes.
