Reference: Global Supply Agreement (GSA), dated April 21, 2005

Dear Greg:

The parties acknowledge that they are still negotiating an amendment to the current GSA which (in addition to other provisions) would create an evergreen term for the amended GSA. MKS has asked for additional time to review Applied’s latest proposal for this amendment and so the parties agree to extend the GSA beyond July 30, 2014 until August 31, 2014.

In the interest of a successful conclusion to negotiations, the following performance criteria will be required of both parties during this period:

Unless the GSA is terminated sooner, the term of the GSA will now expire on August 31st. If, however, MKS fails to perform to the criteria listed above, or if an additional extension period is required, Applied, at its discretion, can modify payment terms which Applied had previously agreed could stay “as is” to Applied’s standard payment terms of net [**] days for a period of no less than [**] days.

All other terms and conditions of the GSA remain unchanged. Additionally, any addenda or other agreements that expire upon the expiration or termination of the GSA shall also be extended through August 31st, unless terminated sooner in accordance with their terms.

Sincerely,

/s/ John A. Casey
