On March 23, 2015, Genpact Limited (“Genpact”) and its indirect, wholly-owned subsidiary Genpact Global Holdings (Bermuda) Limited, an exempted limited liability company organized under the laws of Bermuda (“Genpact Bermuda”), entered into a credit agreement (the “Credit Agreement”) with Genpact Bermuda as borrower and Morgan Stanley Senior Funding, Inc., as lender, under which Genpact Bermuda borrowed $737.5 million, the full principal amount available under the new credit facility. The full amount of the borrowings under the new credit facility was repaid on March 26, 2015.

Borrowings under the Credit Agreement (together with borrowings made on substantially similar terms under a separate credit agreement with Morgan Stanley Senior Funding, Inc. dated as of January 27, 2015, which borrowings were repaid on January 30, 2015) were used in connection with the consummation of certain internal reorganization transactions.

Borrowings under the Credit Agreement bore interest at a rate equal to 2.00% per annum.

The Credit Agreement was guaranteed by Genpact and certain of its subsidiaries. The obligations under the Credit Agreement were secured by the proceeds of the loans held by Genpact and certain of its subsidiaries.

The foregoing description of the Credit Agreement is qualified in its entirety by the full text of the Credit Agreement, which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.

The foregoing description includes forward-looking statements and information that involves risks, uncertainties and assumptions, including but not limited to those listed under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014.
