Item 1.01 Entry into a Material Definitive Agreement.

Amendment to Credit Agreement

On November 1, 2011, Stream Global Services, Inc. (the “Company”) entered into a Second Amendment to Credit Agreement (the “Amendment”), dated November 1, 2011, with Wells Fargo Capital Finance, LLC (“Wells Fargo”), in its capacity as agent for the lenders and bank product providers party thereto, and certain of the Company’s subsidiaries signatory thereto, for purposes of amending the Credit Agreement, dated as of October 1, 2009 (as amended on June 3, 2011 and as thereafter amended, modified and supplemented from time to time, the “Credit Agreement”).

The Amendment increases, effective as of September 1, 2011, certain add-backs to the calculation of Consolidated EBITDA (as defined in the Credit Agreement). The maximum add-back for cash restructuring charges over the life of the Credit Agreement is increased from $20.0 million to $35.0 million, and over any four-quarter period is increased from $10.0 million to $15.0 million.

In addition, the Amendment permits certain present and future subsidiaries of the Company to engage in certain permitted activities relating to the Company’s operations in the Republic of India and the People’s Republic of China. Certain, but not all, of those subsidiaries may be required to become loan parties under the Credit Agreement in the future if certain tests set forth in the Amendment are met. The Amendment also contains a limited waiver to the extent that any existing transfer pricing arrangements between a Loan Party (as defined in the Credit Agreement) and the VIE (as defined in Credit Agreement) violated the covenant in the Credit Agreement prohibiting certain transactions with affiliates, or other provisions in the Loan Documents (as defined in the Credit Agreement).

The foregoing summary description of the Amendment and the transactions contemplated thereby does not purport to be complete and is subject to and qualified in its entirety by reference to the Amendment, a copy of which is attached hereto as Exhibit 10.1 and the terms of which are incorporated herein by reference.
