Administrative Agent, as a condition precedent to the effectiveness of such
Incremental Commitments certified resolutions of the Board of Directors of the
Company authorizing such amount and such opinions of counsel as the

Notwithstanding anything to the contrary in this Agreement, any Incremental

more tranches of Revolving Loan Commitments that are denominated in an
Alternative Currency and/or term loan commitments (which shall be deemed to be
“Revolving Loan Commitments” for purposes of this Section 2.14 (other than
clause (iv) above)), and the Lenders agree that any amendment required to
implement an Incremental Commitment may be effected by the consent of the
Company and only those Lenders that agree to participate in any such tranche,
provided that the aggregate amount of the commitments do not exceed the Dollar
Equivalent of $2,750,000,000 at any time.

(d) Section 7.6 of the Loan Agreement is hereby amended by deleting the text
thereof and inserting in its place the following:

“As of the end of each fiscal quarter, the Company shall not permit the ratio of
(a) Total Debt on such calculation date to (b) Adjusted EBITDA, as of the last
day of such fiscal quarter to be greater than (i) from September 30, 2013 to

updates to information provided to the Lenders in accordance with the terms of
the Loan Agreement except to the extent stated to have been made as of the
Agreement Date, and (ii) no Default exists.

--------------------------------------------------------------------------------

4. EFFECTIVENESS. This Amendment shall become effective upon the Administrative
Agent receiving this Amendment duly executed by the Company and the Majority
Lenders.

of the Loan Agreement shall remain in full force and effect.

each of which shall be deemed to be an original, but all such separate
counterparts shall together constitute one and the same instrument. Delivery of
an executed counterpart of a signature page to this Amendment by telecopier or
electronic transmission shall be effective as delivery of a manually executed
