Credit Agreement Amendment

On October 31, 2011 (the “Amendment Date”), Broadcom Corporation (the “Company”) entered into the First Amendment to Credit Agreement with Bank of America, N.A., as administrative agent, swing line lender and L/C issuer, and the lenders party thereto (the “Amendment”), which amends the Credit Agreement dated as of November 19, 2010, by and among the Company, Bank of America, N.A., as administrative agent, swing line lender and L/C issuer, and the lenders party thereto (as amended by the Amendment, the “Credit Agreement”).

The Amendment provides for, among other things, an extension of the maturity date of the credit facility to November 19, 2016, and a decrease in the interest rate margins applicable to loans made under the Credit Agreement and the commitment fee paid on the amount of the unused commitments thereunder, if any. Loans made under the Credit Agreement (other than swing line loans) will now bear interest, at the Company’s option, at either a Base Rate (as set forth in the Credit Agreement) or a Eurodollar Rate (as set forth in the Credit Agreement) plus a margin that will vary from 0.000% to 0.500% in the case of Base Rate loans and 0.625% to 1.500% in the case of Eurodollar Rate loans, in each case, based upon the ratings assigned to the Company’s senior unsecured debt by Moody’s Investors Service, Inc., and Standard & Poor’s Ratings Services. Borrowings of swing line loans under the Credit Agreement bear interest at a Base Rate plus the margin described above for Base Rate loans. In addition, under the terms of the Credit Agreement, the Company pays a commitment fee on the aggregate amount of any unused commitments in an amount equal to a percentage of such unused commitments. That percentage has been reduced pursuant to the Amendment and will now vary from 0.060% to 0.200% based upon the ratings assigned to the Company’s senior unsecured debt by Moody’s Investors Service, Inc., and Standard & Poor’s Ratings Services.

The Amendment does not change the events of default or financial covenants applicable to the Company and its subsidiaries.

No borrowings of loans under the Credit Agreement were made on or prior to the Amendment Date.

The foregoing description of the terms of the Credit Agreement and the Amendment does not purport to be complete and is qualified in its entirety by reference to the Credit Agreement, attached as Exhibit 10.1 to the Company’s Form 8-K filing dated November 22, 2010, and incorporated herein by reference, and to the Amendment, attached as Exhibit 10.1 hereto, and incorporated herein by reference.
