AMENDMENT NO. 2010-01 TO

MASTER SERVICES AGREEMENT

This Amendment Number 2010-01 (“Amendment 2010-01”), effective as of April 15, 2010 (the “Amendment 2010-01 Effective Date”), is between Health Net, Inc. (“Health Net”), and Cognizant Technology Solutions U.S. Corporation (“Supplier”) (each, a “Party” and collectively, the “Parties”). This Amendment 2010-01 is made with reference to the following:

A. Master Services Agreement. The Parties entered into a Master Services Agreement dated September 23, 2008 (the “Agreement”), as modified from time to time, pursuant to which Supplier provides certain business process outsourcing services to Health Net;

B. Request for Proposal Process. Pursuant to a Change Notice C20100037, dated June 6, 2010, and an amendment contained therein (“CN 20100037”), the parties changed the methodology for measuring Cognizant’s performance of its service level obligations as described more fully in Schedule B of the Agreement;

C. Voided Change Notice 20100037. Recognizing that the amendment contained in Change Notice 20100037 should not be part of a Change Notice, but should instead be a stand-alone amendment, the parties now wish to void Change Notice 20100037 and execute such stand-alone amendment.

NOW, THEREFORE, in consideration of the mutual promises, covenants, agreements and other undertakings set forth herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereby agree as follows:

1. Definitions. Defined terms used in this Amendment 2010-01 shall have the same meaning as in the Agreement unless otherwise specifically defined herein.

2. Voided Change Notice. Change Notice 20100037 is deemed void and of no effect.

3. Amended and Restated Schedule B. Schedule B of the Agreement is deleted in its entirety and replaced with the Schedule B, which is attached and incorporated into this Amendment.

4. Except as amended and modified by this Amendment, all of the terms and conditions of the Agreement shall remain in full force and effect. For the avoidance of doubt, the exhibits to Schedule B remain unchanged by, and are not attached to, this Amendment. This Amendment 2010-01 may not be modified except in writing signed by both parties hereto. This Amendment, the Agreement and exhibits and schedules thereto constitute the entire agreement of the parties with respect to the subject matter contained therein and supersede any and all prior or contemporaneous agreements between the parties, whether oral or written, concerning the subject matter contained herein.

IN WITNESS WHEREOF, the parties hereto by their duly authorized representatives executed this Amendment 2010-01 to be effective as of the Amendment 2010-01 Effective Date.

Final Execution Version

If Supplier fails to meet a Service Level and establishes within two months after such failure that: (a) Health Net’s failure to perform a retained responsibility was the root cause of Supplier’s failure to meet such Service Level (e.g., providing the required infrastructure to host In-Scope Applications); (b) Supplier would have achieved such Service Level but for such Health Net failure; (c) Supplier used Commercially Reasonable Efforts to perform and achieve the Service Level notwithstanding the presence and impact of such Health Net failure; and (d) Supplier is without fault in causing such Health Net failure, then no Service Level Credit shall be assessed against Supplier for any resulting Service Level Failure, and Supplier shall otherwise be excused from achieving such Service Level for as long as Health Net fails to perform such retained responsibility and Supplier continues to use Commercially Reasonable Efforts to prevent, overcome, or mitigate the adverse effects of such failure to the extent required to achieve the applicable Service Level. Supplier shall not be excused from a failure to achieve a Service Level other than under this Section 4.4 or as expressly provided in this Agreement.
