Awards under the MIP
are currently scaled to Mykroliss performance against budget with threshold performance qualifying for 0.5 times target and maximum performance qualifying for 3.0 times target so that, as an illustration of your case using the current award
formula, the possible awards would range from $0 for below threshold performance to $945,000 for maximum performance. The Management Development & Compensation Committee of the Board reviews the MIP award formula annually so that your MIP
participation in 2006 will be under the award formula adopted by that Committee for 2006, provided, that your award level shall not be less than 70% of base salary for that year at target performance.

Annex A



Separation Agreement, dated as of November 21, 2004, by and between Mykrolis Corporation, a Delaware corporation (the Company),
and Gideon Argov (Executive).



RECITALS



1. The Company has
offered Executive employment as its Chief Executive Officer pursuant to an offer letter, dated November 18, 2004 (the Offer Letter).



2. To induce Executive to enter into its employment, the Company is willing to provide Executive with certain severance payments in the event that
his employment terminates under the circumstances described herein.



NOW, THEREFORE, in consideration of their mutual promises, the Company and Executive agree as follows:



1. DEFINITIONS.



1.1. Cause means: (i) Executives conviction of a felony involving a personal act of willful and intentional misconduct or the entry by
Executive of a plea of nolo contendere in connection with such an alleged felony; (ii) the repeated and continual failure of Executive to fulfill the basic duties of his position with the Company; (iii) Executives gross negligence, dishonesty,
willful malfeasance or gross misconduct in connection with his employment with the Company which has had (or is expected to have) a material adverse effect on the business or reputation of the Company or its subsidiaries; or (iv) willful failure by
Executive to follow any lawful directives established for Executive by the Board of Directors. Notwithstanding the foregoing, the deficiencies referred to in clauses (ii), (iii), and (iv) shall constitute Cause only if such deficiency remains
uncured or continues or recurs after ten (10) days notice from the Company specifying in reasonable detail the nature of such deficiency, if such deficiency is capable of cure.



1.2.Good Reason means: (i) failure of the Company to continue the Executive in the position of
Chief Executive Officer or failure of the Board of Directors of the Company to include Executive in the slate of nominees for election as directors after the expiration of Executives normal term; (ii) material diminution in the nature
or scope of the Executives responsibilities, duties or authority; provided, however, that the Companys failure to continue the Executives appointment or election as a director or officer of any person
directly or indirectly controlling, controlled by or under common control with the Company (Affiliate), a change in reporting relationships resulting from the direct or indirect control of the Company (or a successor corporation) by
another corporation and any diminution of the business of the Company or any of its Affiliates or any sale or transfer of equity, property or other assets of the Company or any of its Affiliates shall not constitute Good Reason;
(iii) material failure of the Company to provide the Executive with the base salary and benefits in accordance with the terms of the Offer Letter, excluding an inadvertent failure which is cured within ten business days following notice from
the Executive specifying in detail the nature of such failure; or (iv) material breach by the Company of its obligations under the Offer Letter or of the Indemnification Agreement or Executive Termination Agreement referred to therein.
Notwithstanding the foregoing, the deficiencies referred to in clauses (i) and (iv) shall constitute

Good Reason only if such deficiency remains uncured or continues or recurs after ten (10) days notice from the Executive
specifying in reasonable detail the nature of such deficiency, if such deficiency is capable of cure.



2. Termination of Employment by the Company. If the Company terminates Executives employment for any reason other than Cause (and
other than as a result of death or disability) or if Executive resigns from the Company for Good Reason, the Company will pay Executive a severance benefit in an amount equal to Executives annual base salary as in effect immediately prior to
such termination or resignation. Such severance benefit shall be paid in the form of salary continuation for a period of one (1) year. In addition, the Company will continue healthcare benefits for Executive and his immediate family for one year
following the date of termination or resignation hereunder.



3. Release. Payment of any benefits under this Separation Agreement shall be subject to and expressly conditioned upon Executive executing a release in favor of the Company in form and substance satisfactory to the Company.



4. Confidentiality. During the period that he is
receiving severance benefits hereunder and for a period of two years thereafter, Executive shall hold all confidential information of the Company in his possession in strict confidence and shall not disclose it to any third party. This
non-disclosure obligation shall not apply to information which is in the public domain, subsequently comes into the public domain through no fault of the Executive, Executive is required to disclose by law and has given the Company reasonable prior
notice thereof, or was known to Executive prior to his employment with the Company.



5. Public Comment. In the event of Executives termination of employment, Executive and the Company each hereby agree not to make any disparaging public statements, including statements by means of
any electronic communication, regarding the other party. The parties shall use their reasonable best efforts to agree on the terms of any public statements to be made regarding the circumstances surrounding Executives termination.



6. Withholding. All payments to be made or benefits to be
provided to Executive in accordance with this Separation Agreement shall be made net of all applicable income and employment taxes required to be withheld from such payments.



7. Miscellaneous. This Agreement may be amended only by a written instrument signed by the Company and
Executive. Except with respect to any other agreement between the Company and Executive that is specifically referenced herein and intended to continue beyond the execution of this Agreement, this Agreement shall constitute the entire agreement
between the Company and Executive with respect to the subject matter hereof. This Agreement shall be governed by the laws of the Commonwealth of Massachusetts, other than the provisions thereof relating to conflict of laws. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors, heirs, executors, administrators (in the case of Executive) and assigns. This Agreement may be executed in counterparts, each of which shall be deemed an
original but all of which together shall constitute one and the same instrument.



IN WITNESS WHEREOF, the parties have executed this Separation Agreement effective as of the day first written above.
