Effective as of January 1, 2013, except as otherwise provided in this Letter Agreement, all references in the Agreement to “NAI” or “Company” shall be amended to be references to NC Transaction, Inc. and all references in the Agreement to “Education Division” shall be deemed to be references to Amplify.

As so assigned, the Agreement continues in full force and effect.

2. As of the effective time of the Separation, the first paragraph of Section 1 of the Agreement is hereby deleted in its entirety and replaced as follows: The Company agrees to employ the Executive and the Executive agrees to accept employment with the Company for the Term of Employment hereinafter defined. During the Term of Employment, the Executive, subject to the provisions of this Agreement, shall have the title and the duties of Executive Vice President of New News Corporation. In addition, the Executive shall serve as the Chief Executive Officer of Amplify. As the Chief Executive Officer of Amplify: (i) the Executive will be the most senior officer of Amplify (other than the Executive Chairman of New News Corporation and the Chief Executive Officer of New News Corporation); and (ii) the Executive shall have such duties and authority as are customarily associated with the position of Chief Executive Officer. The Executive shall report directly to the Executive Chairman of New News Corporation and the Chief Executive Officer of New News Corporation.

4. NAI and the Executive hereby agree that the assignment of the Agreement and the terms of this Amendment, including, without limitation, amendments relating to reporting titles or offices, obligations with respect to the election and/or designation of Executive as a director and officer of NEWS CORP and/or the benefit plans in which Executive participates, shall not be circumstances entitling Executive to terminate his employment pursuant to Section 9.

As an inducement to the Executive to enter into the foregoing Amendment, the undersigned hereby guarantees full performance and payment of all of the obligations of NC Transaction, Inc., waiving exhaustion of remedies, including, without limitation, obligations with respect to the election and/or designation of Executive as a director and officer to serve in the capacities and to have the duties set forth in Section 1 of the Agreement, as amended.
