	1A.	TRANSITION OF MANUFACTURING 

1A.1 Move. The parties have agreed that Entegris will move its membrane manufacturing operations currently
conducted in the Premises to the New Entegris Facility in an orderly manner (the “Move”) during the Facility Term. 

1A.2 Timing; Notice. Entegris will not move any equipment or operations sooner than March 2012. Entegris will
provide to Millipore written notice (the “Move Notice” of the date on which Entegris plans to commence the Move (the “Move Date”), which Move Notice will be delivered no later than one year prior to the Move Date, but no later
than February 28, 2013. Subject to the achievement of required safety stocks as described in Section 5.7, Entegris will complete the Move and have vacated the Premises no later than the end of the Facility Term. Promptly after initial
delivery of the Move Notice, Entegris will prepare a detailed move schedule and provide it to Millipore. The parties will review and update the schedule during the Facility Term on a monthly basis as the Move approaches and then progresses.
Millipore will supply its requirements for feasibility and qualification rolls in coordination with the schedule. 
 1A.3
Coordination. The parties will work together in good faith to facilitate such Move to minimize disruptions and costs to both parties. 
 1A.4 Qualification. Prior to the reduction or cessation of production of Membranes at the Premises, Entegris may establish its own new UPE annealing capability at the New
Entegris Facility. Millipore will use its commercially reasonable efforts, in conjunction with Entegris, to qualify the Entegris’ manufacturing process at the New Entegris Facility to enable the supply of qualified Membranes. Entegris will
provide to Millipore in parallel with such qualification a reasonable quantity of rolls of UPE Membrane necessary for Millipore to conduct feasibility and qualification testing. All such feasibility and evaluation rolls provided to Millipore by
Entegris will meet all existing Entegris specifications as agreed by the parties. If, despite each party’s commercially reasonable efforts, Millipore is unable to qualify the Entegris UPE annealing line, Millipore reserves the right to perform
the annealing process itself. In such 

  
 Page 5 of 50

 Fourth Amended and Restated Membrane Manufacture and Supply Agreement Between Millipore Corporation
and Entegris, Inc. dated January 10, 2011 
  

 
circumstances, Entegris shall provide to Millipore a sufficient quantity of extracted gel rolls, at appropriately adjusted prices, to enable Millipore to produce sufficient finished product to
meet Entegris’ obligations for such finished product. 
 1A.5 No Supply Disruption.
Notwithstanding the Move, Entegris will at all times during the Term of this Agreement continue to meet its supply obligations to Millipore under this Agreement of any Membranes from a manufacturing process qualified by Millipore. It is the
expectation of the parties that Entegris will produce Membranes from both facilities initially, noting that for some process operations duplicate equipment does not exist, and, after the Facility Term, if the New Entegris Facility and its processes
are qualified by Millipore, solely from the New Entegris Facility. 
 1A.6 No VMF4 Disruption.
Notwithstanding the Move, Millipore will at all times during the Term of this Agreement continue to meet its obligations to Entegris under this Agreement to provide hydrophilization of any Membranes on its VMF4 Line (or MML line if approved by
Entegris). 
 1A.7 Costs. Entegris will bear all costs of dismantling, packaging, freight, shipping,
installation, testing and requalification of all Entegris Equipment to be removed from the Premises. 
 1A.8
Transfer to New Annealing Line. If Entegris’ new UPE annealing process can be qualified successfully by Millipore as provided above, then after such qualification Millipore shall have Millipore membrane processed by
Entegris on the new Entegris annealing machine with pricing based on the costs associated with the new machine and forego any payment for existing Film I Annealing machine hours from Entegris. Prior to any successful qualification of such new
process to Millipore’s reasonable satisfaction, Millipore shall have Millipore membrane continue to be processed on the existing Film I annealing machine at the Premises with Entegris continuing to be charged the same rates and pricing then in
effect. Any such shifting of production shall not result in a termination of the Agreement, which may be only be terminated in accordance with its terms. 
  

	2.	LEASE OF THE PREMISES 

In order to enable Entegris to manufacture UPE Membranes, including Treated Flat Sheet UPE Membranes and Other Flat Sheet UPE Membranes,
and Treated Other Entegris Membranes in the same production areas at Millipore’s facility at 80 Ashby Road, Bedford MA. and/or such additional, reduced or substituted areas all as described in greater detail in Exhibit B hereto, and with the
same processes as such UPE Membranes and Treated Other Entegris Membranes were manufactured prior to the Effective Date (both (i) for its own use and sale and for its sale of UPE Products and (ii) for supply of Flat Sheet UPE Membranes to
Millipore as provided in this Agreement), Millipore and Entegris agree to the arrangements regarding Entegris’ use of the Premises as are set forth in Exhibit B hereto for the duration of the Facility Term.

	 	5.4.1	Millipore will provide Entegris with a rolling one-year forecast of its demand for UPE Membranes hereunder, by calendar quarter (a “One-Year
Forecast”), which will be updated on a quarterly basis, at least thirty (30) days prior to the start of each calendar quarter. The sub-forecast for the first three (3) months within any One-Year Forecast shall be referred to as a
“3 Month Forecast”. Millipore must provide Releases for delivery, during the three (3) months covered by any 3 Month Forecast, of UPE Membranes in at least those quantities set forth in such 3 Month Forecast. Except for such semi
binding nature of the 3 Month Forecasts as described more specifically at 5.4.3 below, the One-Year Forecasts will be used for planning purposes only and are not binding. Entegris will ship UPE Membranes so as to arrive on the delivery date set
forth in a Release, provided that the delivery date set forth in such Release is not less than thirty (30) days following the date Entegris receives such Release and provided that the quantities set forth in such Release, together with those in
all other Releases calling for delivery during the same quarter, are not more than thirty percent (30%) greater than the quantities provided in the applicable 3 Month Forecast. For any Releases calling for quantities more than thirty percent
(30%) greater than the quantities provided in such 3 Month Forecast, Entegris shall use commercially reasonable efforts to deliver such quantities within sixty (60 ) days following the date Entegris receives such release or as soon as
practicable thereafter. 

  

	 	5.4.2	Within ten (10) days after receipt of each One Year Forecast, Entegris will provide a non-binding, good faith projection of its UPE Membrane
manufacturing volume (broken down between philic and phobic Membranes), by calendar quarter, for the upcoming four calendar quarters. This information will be used by Millipore for budgeting of resources and revenue, and for the determination of
budgeted Machine Hourly Rates for purposes of Section 7.1.2. 

  

	 	5.4.3	Millipore’s requirements for membranes for an upcoming quarter shall be submitted to Entegris in the form of a firm forecast before the start of that quarter.
Millipore shall be entitled to change the forecast without penalty or other change if the written cancellation notice is received by Entegris prior to the requested membrane lot being extruded. Millipore shall be entitled to increase volume of
membrane requested during the quarter by issuing a forecast change in writing and Entegris agrees to make reasonable efforts to accommodate the requested additional volume. Actual purchase orders will be issued following lot completion in order to
assure that ordered quantities match quantities available.

and Entegris, Inc. dated January 10, 2011 
  

	5.5.	Prices; Delivery and Payment Terms. Membrane prices shall be as set forth in Section 7.5 hereof. Payment terms for the sale of
Membranes hereunder shall be as set forth in Section 7.6 hereof. Delivery terms for all Membranes will be FOB 80 Ashby Road, Bedford, MA. 

  

	5.6	Continuing Supply Discussions. The parties agree to commence good faith discussions in the first calendar half of 2012 regarding the
possibility of continuing the supply of some Membranes from Entegris to Millipore beyond the Term of this Agreement on terms and conditions mutually acceptable to both parties, if any. 

 

	5.7	Safety Stock. 

 5.7.1 Each party acknowledges that the generation of a sufficient safety stock of UPE Membrane inventory meeting specifications and produced using a qualified process (the “Safety Stock”)
is appropriate. Accordingly, during the Term Millipore will determine routine safety stock levels required and include sufficient membrane quantities in quarterly forecasts to achieve the desired safety stock levels. 

5.7.2 Commencing in the calendar quarter immediately following Millipore’s receipt of the Move Notice from Entegris, Millipore
will supplement each One-Year Forecast thereafter with an extended forecast of demand which Millipore reasonably believes it will require during the six month period immediately following the Move (“Move Buffer Stock”). Entegris will
review such Move Buffer Stock forecast and communicate to Millipore any concerns Entegris may have regarding its ability to produce the requested quantity. The portion of the Move Buffer Stock that has been QA released as finished rollstock will be
owned and carried by Millipore. If it is agreed that Entegris will hold some of the Move Buffer Stock as gel rolls, then Entegris will own and carry such inventory until such time as it is converted to acceptable finished rollstock. 

5.7.3 Entegris will not commence the Move, including the reduction or cessation of production or the movement of any Entegris
Equipment, until the parties have created an inventory of Safety Stock of at least the amount of the Move Buffer Stock. Until commencement of the Move, Entegris will make all commercially reasonable efforts to maintain the Move Buffer Stock at such
amount. 
 5.7.4 The parties agree that production in any calendar quarter in excess of, or below, 200,000 feet shall
increment or decrement, respectively, the amount of Safety Stock. In addition, material returns for verified quality issues related to the 

  
 Page 14 of 50

 Fourth Amended and Restated Membrane Manufacture and Supply Agreement Between Millipore Corporation
and Entegris, Inc. dated January 10, 2011 
  

 
portions of the process controlled by Entegris will reduce the amount of Safety Stock, foot for foot. The parties will review the amount of Safety Stock on a monthly basis and will mutually
determine the then current level of Safety Stock. The parties acknowledge that the Safety Stock requirements described in this section are exclusively for the benefit of Millipore’s supply needs. Millipore will provide the necessary storage
space for any Safety Stock, including the Move Buffer Stock, which storage space shall be outside the then current Premises. 

5.7.5 Although fully treated, finished Membrane is preferable, if the parties mutually agree that it is a necessity in order to
facilitate the Move, up to fifteen percent (15%) of the Move Buffer Stock may be comprised of gel rolls, which are composed of Flat Sheet UPE Membrane that has not yet been processed through the Annealing Line. Any such gel rolls shall be
processed at the Premises when such rolls are actually processed. 
  

	6.	TERM AND TERMINATION 

 

	6.1.	The effective period of this Agreement (the “Term” or “Term of this Agreement”) shall begin on the Effective Date and continue thereafter
until March 31, 2014 or until earlier termination in accordance with Section 6.2. Any Release issued by a Supplied Party before the effective date of termination and in accordance with Section 5.4 hereof shall be fulfilled by the
Supplying Party. 

  

	6.2.	Either party may terminate this Agreement prior to December 31, 2012 without prejudice to any rights or liabilities accruing up to the date of termination:

  

	 	(i)	in the event of a material breach by the other party of any of the terms and conditions of this Agreement, by giving the other party written notice of such
breach, provided that such breach shall not have been cured within one hundred twenty (120 ) days following such notice; or, 

  

	 	(ii)	immediately, by written notice thereof, if any of the following events or an event analogous thereto occurs: 

 

	 	a.	an adjudication has been made that the other party is bankrupt or insolvent; 

 

	 	b.	the other party has filed bankruptcy proceedings or has had such proceedings filed against it, except as part of a bona fide scheme for reorganization;

  

	 	c.	a receiver has been appointed for all or substantially all of the property of the other party; 

 

	 	d.	the other party has assigned or attempted to assign this Agreement for the benefit of its creditors; or

 Page 15 of 50

 Fourth Amended and Restated Membrane Manufacture and Supply Agreement Between Millipore Corporation
and Entegris, Inc. dated January 10, 2011 
  

	 	(iii)	at any time for convenience of the terminating party upon twenty-four (24) months prior written notice to the other party. 

 

	6.3.	Termination under this Section 6 shall be in addition to and not a substitute for other rights or causes of action of the terminating party.

  

	6.4.	Termination of this Agreement shall not in any way operate so as to impair or destroy any of the rights or remedies of either party, either at law or in equity,
nor shall it relieve the parties of their obligations pursuant to Sections 1, 3.1, 4.5, 4.6, 4.7, 6, 8, 9, and 13 through 16 hereof, each of which shall survive the termination or expiration of this Agreement. 

 

	7.	PRICES AND PAYMENTS  

 

	7.1.	Machine Hourly Rates. The hourly rates (“Machine Hourly Rates”) for use by Entegris of Millipore’s VMF4 Line, Film 1
Annealing Line and Mix Room equipment (the “Machines”), and the invoicing thereof, shall be as set forth in this Section 7.1. Machine usage (including production and research and development usage) shall be calculated in accordance
with the formula set forth in Annex 2. 

  

	 	7.1.1.	 Machine Hourly Rates. Commencing on the Effective Date, the Machine Hourly Rates set forth in Annex 1, subject to the annual
adjustments as set forth below in this Section, shall be applicable from the Effective Date through the end of the period of the Term of this Agreement. The Machine Hourly Rates shall be adjusted annually as of January 1 of each year, beginning
in calendar year 2010, to reflect (i) the then most recent August-to-following-August percentage changes, up or down, in the Producer Price Index for the industry group Pharmaceutical Preparation Manufacturing (series identification number
PCU325412325412), (ii) any demonstrated increases in Millipore’s costs associated directly with use of the Machines hereunder and which costs are extraordinary, not presently anticipated and not reflected in the Producer Price Index used
pursuant to clause (i) above, and (iii) changes to depreciation charges as a result of capital improvements to the Machines for the production of Membranes, as set forth in Section 7.4.2; provided, however, that commencing on
January 1, 2009 the Machine Hourly Rates for Millipore’s VMF4 Line will not be subject to such annual changes and will remain at $313.38 per hour through December 31, 2012 after which VMF4 Line hourly rates may be adjusted annually
following the same approach used for other machine hourly rates as described above. Machine Hourly Rates to Entegris are independent of Millipore production volumes on the Machines. 7.1.2. Invoicing for Machine Hourly Rates.
Millipore shall be entitled to invoice Entegris monthly for Machine usage following the end of each month. The Machine Hourly Rates used for the first two months of each calendar quarter shall be the average Machine Hourly

  
 Page 16 of 50

 Fourth Amended and Restated Membrane Manufacture and Supply Agreement Between Millipore Corporation
and Entegris, Inc. dated January 10, 2011 
  

	 	 
Rates that would apply for the budgeted use of each Machine for such quarter, as calculated by Millipore based on the then most recent projections provided by Entegris pursuant to
Section 5.4.2 hereof. The invoice for the third month of each calendar quarter shall be adjusted to effect a “true up” to actual Machine usage by invoicing for the net difference between the Machine Hourly Rate applicable to the
actual hourly usage of the Machine in question for the entire quarter multiplied times the actual hours of usage of such Machine for the quarter less the amounts invoiced for usage of such Machine for the first two months of the quarter. This
“true up” is so that Entegris effectively pays for all of a quarter’s hours at the Machine Hourly Rates appropriate for those total hours. 

 

	7.2.	Occupancy Rates. Commencing on the Effective Date, rates for occupancy and use of the Premises shall be as set forth in
Exhibit B.  

  

	7.3.	Support Rates. Commencing on the Effective Date, rates for extraordinary Millipore supervisory, operational assistance and
technical support (as described in Section 3.2 hereof) that are currently in use by the parties during 2005 shall be applicable from the Effective Date through December 31, 2008. Commencing on January 1, 2009, rates for extraordinary
Millipore supervisory, operational assistance and technical support (as described in Section 3.2 hereof) shall be as shown in Annex 1. These rates will be adjusted annually as of January 1 of each year, beginning in calendar year 2010, to
reflect (i) the then most recent August-to-following-August percentage changes, up or down, in the Producer Price Index for the industry group Pharmaceutical Preparation Manufacturing (series identification number PCU325412325412) and
(ii) any demonstrated increases in Millipore’s costs associated directly with providing such support hereunder and which costs are extraordinary, not presently anticipated and not reflected in the Producer Price Index used pursuant to
clause (i) above. 

  

	7.4.	Impact of Capital Investment on Prices. 

  

	 	7.4.1.	Entegris shall be responsible for funding required capital improvements to the Entegris Equipment for production of hydrophobic Membranes. Millipore shall be
responsible for funding required capital improvements to the Millipore Equipment for production of hydrophilic Membranes. To the extent that capital improvements are required for the Millipore Equipment used in the production of hydrophobic
Membranes, responsibility for funding that capital improvement shall be mutually agreed upon in accordance with Section I.1.7 of the Supplement. If one party funds the purchase of additional equipment for use in manufacture of UPE Membranes at the
Premises, that equipment shall be owned by the funding party.

 Fourth Amended and Restated Membrane Manufacture and Supply Agreement Between Millipore Corporation
and Entegris, Inc. dated January 10, 2011 
  

	 	7.4.2.	Changes to depreciation charges as a result of capital improvements to the Equipment for the production of Membranes will be reflected in the appropriate work
center rates and would be part of the rate adjustment process set forth in Sections 7.1.2 and 7.3. Millipore and Entegris each agree to inform the other of capital purchases that may eventually affect proposed rate/price changes hereunder no later
than the time that purchase orders for such capital purchases are placed. 

  

	 	7.4.3.	Millipore shall have approval authority with respect to any Entegris proposed modifications to VMF 4 equipment for UPE Membrane processing. Millipore agrees that
proposed modifications to the VMF4 equipment for non-Entegris UPE Membrane processing that could influence the processing of UPE Membranes on the VMF 4 equipment shall be reviewed with Entegris and shall be subject to mutual agreement.

  

	 	7.4.4.	Millipore shall have approval authority for any Entegris proposed modifications to Film 1 manufacturing process for UPE Membranes. Financial impact of those
modifications would be mutually agreed upon prior to proceeding. 

  

	 	7.4.5.	In the event of a process change to either the Film 1 or VMF4 lines, Millipore shall be responsible for change control management for any impact on Millipore
products. Likewise, Entegris would be responsible for change control management for any impact on Entegris products. 

  

	7.5.	Membrane Prices. 

  

	 	7.5.1.	Intentionally Omitted. 

  

	 	7.5.2.	Commencing on the Effective Date through December 31, 2009, until adjusted pursuant to Section 7.5.3, prices for Flat Sheet UPE Membranes to Millipore
produced at the Premises, together with up to eight (8) rolls produced at the New Entegris Facility that are used to ascertain basic feasibility, shall be at Entegris’ Manufacturing cost plus fifteen percent (15%). For Flat Sheet UPE
Membranes produced at the New Entegris Facility (other than the rolls for feasibility evaluation as described and priced above), prices shall as set forth on Annex 3 for the Term of this Agreement. The parties acknowledge that all Flat Sheet UPE
Membranes will be produced at the New Entegris Facility after June 30, 2012. 

  

	 	7.5.3.	Entegris has notified Millipore as to the adjusted Manufacturing Cost to be in effect for calendar year 2009 for the Membranes to be supplied by Entegris that
will be produced at the Premises and shall make available an “open-book” review of such Manufacturing Cost. Membrane Prices hereunder will be adjusted as of January 1, 2010 to reflect such adjusted Manufacturing Cost. Without limiting
the factors involved in determining Manufacturing Cost, the Manufacturing Cost of UPE Membranes shall take into account the budgeted Machine Hourly Rates based on projected annual UPE Membrane manufacturing volume.

hereto, is the entire agreement between the parties with respect to the subject matter hereof, and supersedes any prior negotiations and agreements or understandings and any contemporaneous oral agreements or understandings with respect to the
subject matter hereof. Without limiting the generality of the foregoing, the Old Agreement shall be deemed replaced in its entirety by this Agreement as of the Effective Date, provided that the Old Agreement shall continue to apply to all activities

 EXHIBIT B 
 Lease Terms 
  

	1.	Millipore hereby leases to Entegris, and Entegris hereby leases from Millipore, the areas within Buildings “C”, “D” and “F” of
Millipore’s facility at 80 Ashby Road, Bedford, MA, as more specifically described and shown in Attachment A to the terms set forth in this Exhibit B (collectively, the “Lease Terms”), as such areas may be added to, reduced or
substituted for as provided in these Lease Terms (the “Premises”), including as specifically set forth in Section 3.3, solely for purposes of its manufacture of UPE Membranes, and PFA Hollow Fiber Membranes and warehousing of raw
materials and components used in such manufacture, and for no other purposes except as Millipore may specifically authorize in its sole discretion. 

  

	2.	The Lease of the Premises shall commence as of the Effective Date and continue through the end of the Facility Term, or until such time as Entegris has removed all
Entegris Equipment from the Premises in accordance with the terms of Section 4.6.1 of this Agreement. Subject to achievement of the required Safety Stock as set forth in the Agreement at section 5.7, Entegris shall have vacated the Premises by
the end of the Facility Term. 

  

	3.	Entegris shall pay to Millipore rent/occupancy charges for the Premises (“Rent”) as follows: 

 

	3.1	From the Effective Date through December 31, 2009, Rent shall be $ 91.14 per square foot of the Premises. Rent shall be adjusted annually thereafter, on a
square-footage basis, on January 1 of each year, beginning with 2010, as follows: (a) The utility portion of the Rent (which for calculation of the current Rent shall be 39.8% of the total Rent) will be adjusted by the same percentage as
the then most recent August-to-following-August percentage change in the average actual cost per kilowatt hour paid by Millipore for the 80 Ashby Road, Bedford facility (e.g. for calendar year 2010, the percentage change in such average cost from
August 2008 to August 2009); (b) the remainder of the Rent (which for calculation of the current Rent shall be 60.2% of the total Rent) will be adjusted by the same percentage change as the then most recent August-to-following-August percentage
change in the Producer Price Index for the industry group – Pharmaceutical Preparation Manufacturing (series identification number PCU325412325412) (e.g. for calendar year 2010, the percentage change in such index from August 2008 to August
2009). Rent shall be payable by Entegris monthly on or before the fifth day of each month. 

  

	3.2	It is acknowledged and agreed that in the event that the square footage of the Premises is adjusted during the Facility Term as a result of a shift of production as
provided in this Agreement or pursuant to Section 3.3, the corresponding Rent due to Millipore hereunder shall be adjusted accordingly. 

  
 Page 31 of 50

	3.3	The parties acknowledge that implementation of the Move will likely result in decreasing production by Entegris at the Premises during the Facility Term and therefore
commensurate reductions in Entegris’ need for the full original Premises. Accordingly, at least ten (10) days prior to the end of any month during which Entegris believes it has vacated any portion of the Premises, Entegris will notify
Millipore of such occurrence in writing, such notice to include with reasonable specificity the portion of the Premises vacated and the square footage proposed to be surrendered. Upon receipt of the notice, Millipore will promptly review in good
faith with Entegris the vacated portion of the Premises to confirm that such space has been vacated and, to the extent applicable, complies with Section 7.6 with respect to the condition of the portion of vacated Premises. Upon the
parties’ mutual agreement of the actual surrender and the square footage affected, the parties will agree on the revised square footage of the Premises and amend Attachment A to reflect such reduce square footage, to be effective for the
ensuing month for purposes of calculating Rent pursuant to Sections 3.1 and 3.2 thereafter until any further reductions occur. 

  

	4.	 At all times during the Facility Term, those employees or consultants of Entegris that are involved regularly or from time to time in the manufacture
of UPE Membranes and reasonably need access to the Premises for such purposes, and that are not objectionable to Millipore in its sole reasonable discretion, (“Entegris Permitted Persons”) shall have access to the Premises for the purposes
of manufacturing of UPE Membranes and Treated Other Entegris Membranes and warehousing of raw materials and components used in such manufacture, including reasonable ingress to and egress from the Premises through other parts of Millipore’s
facility at 80 Ashby Road. Notwithstanding, to the extent that Millipore believes in its sole reasonable discretion that an individual or individuals are objectionable and hence prohibited from entering the Premises, it shall provide Entegris a
written summary of the reasons for, and basis of, such belief within three (3) days of notifying Entegris of such a determination. Without limiting the generality of the foregoing, Millipore shall provide security badges to such Entegris
Permitted Persons enabling their entry to the Premises. Entegris agrees to provide an initial list of proposed Entegris Permitted Persons to Millipore’s facilities personnel (as shall be identified to Entegris by Millipore) promptly after the
execution of this Agreement, and to promptly update such list from time to time as necessary with any additions or deletions. In addition, Entegris Permitted Persons shall be, to the same extent, on the same terms, and subject to the same rules and
restrictions, as provided to Millipore employees in general, (i) provided access to and use of restrooms, parking areas, driveways and footways, other common areas reasonably necessary to be used by such Entegris Permitted Persons, and
conference rooms as reasonably necessary for meetings relating to UPE Membranes manufacture, and (ii) permitted reasonable use of mailroom services, telephone and voicemail systems, information services, fax, copy machines,
cafeteria/refreshment services, and the like. Without limiting the generality of the parties’ respective obligations of confidentiality and non-use as 

  
 Page 32 of 50

	 	 
described in this Agreement, Entegris hereby agrees that any Confidential Information of Millipore that the Entegris Permitted Persons gain access to as a result of their presence in
Millipore’s facility shall be subject to strict obligations of confidentiality and non-use as provided in, and subject to the limitations and other provisions of, Section 13 of this Agreement. 

 

	5.	Millipore shall have the right, upon at least twenty-four (24) months written notice to Entegris, to relocate all or any portion of the Premises to any other
location of comparable size and utility within its 80 Ashby Road facility. The parties shall cooperate in enabling any such relocation to occur in a coordinated manner so as to minimize interruption both to Entegris’ manufacturing activities
hereunder and Millipore manufacturing and other activities at such facility. Millipore shall reimburse Entegris for all reasonable and substantiated costs incurred by Entegris in connection with any such relocation. The definition of the
“Premises” shall be modified to include any such relocated space. 

  

	6.	Entegris shall comply with all federal, state or local statutes, ordinances, codes, rules, regulations, orders and decrees (“Laws”) applicable to the conduct
of its business on the Premises. Entegris shall not cause or permit any hazardous substances to be transported to or from, brought upon, kept, stored or used in or about the Premises by, its agents, employees, contractors or invitees, except for
such hazardous substances as are reasonably necessary in the performance of the activities permitted under this Agreement. Any hazardous substance permitted pursuant to the foregoing sentence and all containers therefore shall be used, kept, stored,
transported and disposed of in a manner that strictly complies with all applicable Laws relating thereto as now or at any time hereafter during the Facility Term may be in effect. Except as may be otherwise agreed between the parties in writing,
during the Facility Term responsibility for regulatory, health, safety and environmental compliance, as well as hazardous and solid waste disposal, generated by Entegris’ use of the Premises and Entegris’ manufacture of UPE Membranes and
Treated Other Entegris Membranes shall be allocated in accordance with Section I.4 of the Supplement. 

  

	7.	Repairs and Alterations; Condition of Premises 

  

	7.1	 Entegris agrees that it shall, throughout the Facility Term, maintain the Premises in good and operable repair and in such condition as may be required
by any laws, ordinances, regulations or requirements of any public authorities having jurisdiction and shall not permit or allow to remain any waste or damage to any portion of the Premises, except as may be permitted herein, provided, however, that
Millipore shall be responsible for maintaining, keeping in good repair and, if necessary, replacing the foundation, the exterior and interior walls, the roof, floors and ceilings, the heating, ventilating and air-conditioning system, all utility
systems (including water, gas, electricity, drainage, and sewerage), conduits, fixtures and equipment, all meters and all other fixtures and equipment within or appurtenant to the Premises; provided, further, that Entegris shall promptly

  
 Page 33 of 50

	 	 
reimburse Millipore, as additional Rent, for the cost of any such maintenance, repair or replacement to the extent necessitated or occasioned by any omission, negligence, fault or act of
Entegris, its partners, officers, employees, agents, independent contractors or invitees; provided, however, that any maintenance, repair or replacement necessitated by fire or other casualty shall be subject to the provisions of Section 10
below. Entegris’ maintenance of the Premises shall include, without limitation, cleaning the Premises regularly. If Entegris fails to perform such maintenance, within fifteen (15) days after written notice from Millipore (or as promptly as
practicable if Entegris’ failure to make such repairs or replacements or perform such maintenance constitutes an emergency or poses a threat to persons or property), then Millipore may elect to make the same at Entegris’ cost (without
creating any obligation on behalf of Millipore to do so). If Millipore fails to perform, or commence performance of, any maintenance, replacement or repair for which it is obligated under these Lease Terms within fifteen (15) days after written
notice from Entegris (or as promptly as practicable if Millipore’s failure to make such repairs or replacements or perform such maintenance constitutes an emergency or poses a threat to persons or property), then Entegris may elect to make the
same at Millipore’s cost (without creating any obligation on behalf of Entegris to do so). 

  

	7.2	Entegris agrees that it will not make any installations, alterations, additions or improvements to or upon the Premises (including without limitation the installation
of signs) without the prior written consent of Millipore, which consent shall not be unreasonably withheld, conditioned or delayed if such installations, alterations, additions or improvements are reasonably consistent with the permitted use of the
Premises hereunder; provided, however, that if any proposed installations, alterations, additions or improvements, in Millipore’s reasonable judgment, are either unlikely to be of use to Millipore after the termination of the Lease or are
likely to be expensive or difficult to remove, then Millipore may require Entegris to remove such installations, alterations, additions or improvements at the expiration or earlier termination of the Facility Term. Upon completion of any
installations, alterations, additions or improvements to the Premises, Entegris shall provide Millipore with a copy of any plans and specifications (or similar drawings) prepared for Entegris in connection therewith; if Entegris is required to
submit plans and specifications which have been prepared by a licensed civil engineer or architect in order to obtain a building permit for any such installations, alterations, additions or improvements, then upon completion of such installations,
alterations, additions or improvements, Entegris shall provide Millipore with a copy of the plans and specifications which have been stamped as appropriate by such licensed civil engineer or architect, as appropriate. 

 

	7.3	 All work on or at the Premises for which Entegris is responsible or permitted to perform under these Lease Terms shall be performed at Entegris’s
cost and only by contractors and subcontractors approved in writing by Millipore, which approval shall not be unreasonably withheld. Entegris shall cause all contractors 

  
 Page 34 of 50

	 	 
and subcontractors to procure and maintain insurance coverage naming Millipore as an additional insured against such risks, in such amounts and with such companies as Millipore may reasonably
require. Entegris agrees that it will procure, at its sole cost and expense, all necessary permits before making any repairs, installations, alterations, additions, improvements or removals. Millipore agrees that it will reasonably cooperate with
Entegris, at no out-of-pocket cost to Millipore in obtaining any permits, licenses or approvals related to the Premises. Entegris agrees (a) that all repairs, installations, alterations, improvements or removals done by or on behalf of Entegris
(including without limitation the installation of signs) shall be done in a good and workmanlike manner in conformity with all applicable laws, ordinances and regulations of all public authorities (and Entegris shall be responsible for any
additional installations or improvements required by any such laws, ordinances or regulations as a result of any repairs, installations, alterations, improvements or renewals done by or on behalf of Entegris) and all insurance inspection or rating
bureaus having jurisdiction, (b) that the structure of the buildings in which the Premises are located or the operations in any other party in such buildings will not be endangered or impaired as a result of any such repairs, installations,
alterations, improvements or removals done by or on behalf of Entegris, and (c) that Entegris will repair any and all damage caused by or resulting from any such repairs, installations, alterations, additions, improvements or removals,
including, without limitation, the filling of holes. Entegris agrees to save Millipore harmless from, and indemnify Millipore against, any and all claims by third parties for injury, loss or damage to persons or property to the extent caused by or
resulting from the doing of any such repairs, installations, alterations, improvements or removals by or on behalf of Entegris. Entegris agrees to pay promptly when due all charges for labor and materials in connection with any work done by Entegris
or anyone claiming under Entegris upon the Premises so that the Premises and all such buildings shall at all times be free of liens in respect of such labor and materials. If such a lien is filed, then Entegris shall immediately, after Millipore has
delivered written notice of the filing thereof to Entegris, either pay the amount of the lien or diligently contest such lien. If Entegris fails to timely take either such action, and after written notice to Entegris of its intention to do so, then
Millipore may pay the amount of the lien, and any amounts so paid, including expenses and interest, shall be paid by Entegris to Millipore immediately after Millipore has invoiced Entegris therefor, and until paid, such amount shall be additional
Rent. 

  

	7.4	Millipore may in its discretion and at its own cost, but shall not be obligated to, make repairs, installations, alterations, additions or improvements to the Premises
at any time during the Facility Term as it determines necessary or appropriate, provided that no such work will be done if it will materially adversely impact Entegris’ use of the Premises, unless Millipore will have previously made
accommodations to eliminate or minimize such adverse impact and reasonable advance written notice has been given to Entegris. 

  
 Page 35 of 50

	7.5	Entegris acknowledges that the Premises are being leased in their “AS IS” condition as of the Effective Date and that no warranties or representations,
express, implied or statutory, have been made by Millipore or any agent, employee or representative of Millipore to Entegris, as to condition (environmental or otherwise), compliance with law, or fitness or suitability for any purpose other than as
hereinafter set forth, all of which are expressly disclaimed. Millipore agrees that if at any time during the Facility Term the Premises are altered by an act or omission of Millipore (other than as specifically permitted in Section 5 of these
Lease Terms) such that Entegris is not reasonably able to conduct such manufacturing and warehouse operations in substantially the manner in which it had been conducting such operations prior to the Effective Date, that circumstance shall constitute
a material breach by Millipore of its obligations under this Agreement and that Entegris may then terminate this Agreement upon written notice to Millipore. Entegris acknowledges that except as set forth herein, Entegris has not been induced or
persuaded by, nor has Entegris relied upon, any statement, promise or representation made by Millipore or any agent, employee or representative of Millipore, orally or in writing, as an inducement to entering into this Agreement including, without
limitation, those relating to land use, zoning, hazardous or toxic wastes or other environmental matters. 

  

	7.6	At the expiration or earlier termination of the Facility Term Entegris shall surrender all keys to the Premises, remove all its furnishings, fixtures, equipment
(including the Entegris Equipment, subject to any provisions in this Agreement to the contrary) and other personal property now or hereafter located in the Premises, purchased or leased by Entegris with its own funds, which are not affixed to the
buildings in which the Premises are located. Entegris may also so remove any furnishings, fixtures, equipment which are affixed to buildings in which the Premises are located if Millipore has agreed to such removal in writing. Entegris shall repair
all damage caused by any such removal, and yield up the Premises broom-clean and in the same good order and repair in which Entegris is obliged to keep and maintain the Premises by the provisions of these Lease Terms. Any property not so removed
shall be deemed abandoned and may be retained by Millipore or may be removed and disposed of by Millipore in such manner as Millipore shall determine and Entegris shall pay Millipore the directly related and reasonable cost and expense incurred by
Millipore in effecting such removal and disposition and in making any incidental repairs and replacements to the Premises.

counsel fees, to the extent arising from (a) any act, omission, fault or negligence of Entegris, its officers, directors, agents, employees, independent contractors, licensees, or invitees, and relating to the presence of any of the foregoing
persons or of Entegris’ operations on the Premises or anywhere at the 80 Ashby Road facility. 

  

	8.2	Millipore agrees that during the Facility Term and for such further time as Entegris shall occupy or hold the Premises or any part thereof pursuant to a reasonable
claim of right, Entegris shall not be liable to Millipore and Millipore shall defend (with counsel reasonably acceptable to Entegris), indemnify, and hold Entegris, its officers, directors, agents, employees, independent contractors, and invitees
harmless from and against any and all liability for all injuries, losses, accidents or damage to any person or property, and from all claims, actions, proceedings and costs in connection therewith, including reasonable counsel fees, to the extent
arising from any act, omission, fault or negligence of Millipore, its officers, directors, agents, employees, independent contractors, licensees, or invitees and relating to the presence of any of the foregoing persons on the Premises or relating to
Millipore’s operations on the Premises or anywhere at the 80 Ashby Road facility. 

  

	8.3	Each of Millipore and Entegris hereby releases and waives any claim it might have against the other for any loss or damage caused by theft, destruction, fire or any
other casualty, regardless of whether such loss or damage shall be brought about by the fault or negligence of the other party or its agents, to the extent the same (a) is insured against under any insurance policy that covers the Premises or
the buildings in which the Premises are located, Millipore’s or Entegris’ fixtures, personal property, leasehold improvements or business, or (b) is required to be insured against under the terms hereof, it being understood and agreed
that the waiving party reserves any rights with respect to any excess loss or injury over the amount recovered on account of such insurance. Each of Millipore and Entegris agrees to cause its insurance carrier to endorse all applicable policies
waiving the carrier’s rights of recovery under subrogation or otherwise against the other party.

property, and from all claims, actions, proceedings and costs in connection therewith, including reasonable counsel fees, arising from any release of hazardous waste by Entegris or its employees or agents in the Premises, only to the extent not
caused by Millipore or its employees or agents. 

  

	9.	Insurance 

  

	9.1	During the Facility Term, Millipore shall maintain all risk property insurance in an amount at least equal to the replacement cost of (a) the buildings in which
the Premises are located and (b) Millipore property and equipment inside those buildings (excluding Entegris’ personal property and any alterations, installations, additions or improvements made to such buildings by Entegris). Such
insurance may be maintained under a blanket policy covering the Premises and other real estate of Millipore or its affiliated business organizations. The policies of such insurance may be payable in case of loss to the holders of any mortgages upon
such buildings or the 80 Ashby Road facility as their interests may appear. Entegris shall be named as an additional insured on such Millipore property insurance, as its interests may appear. Certificates of insurance evidencing all such coverages
and Entegris additional insured status for the foregoing shall be supplied to Entegris promptly upon execution of this Agreement and as such policy(ies) renew or are changed. 

 

	9.2	During the Facility Term, Entegris will maintain at its own expense comprehensive general liability insurance, including umbrella coverage, with respect to the Entegris
Equipment and its operations on the Premises, naming Millipore as additional insured, in amounts which shall, as of the Effective Date, be not less than Five Million Dollars ($5,000,000.00) with respect to injuries to any one person and not less
than Five Million Dollars ($5,000,000.00) with respect to injuries suffered in any one accident, and not less than Five Million Dollars ($5,000,000.00) with respect to property damage liability. From time to time during the Facility Term, Millipore
shall have the right in its reasonable discretion to require that the limits of such insurance coverage be increased, provided however, that such increases shall be in accordance with limits that are customarily carried in the metropolitan Boston
area on property similar to the Premises used for similar purposes. 

  

	9.3	 During the Facility Term, Entegris shall maintain workers compensation insurance covering all of Entegris’ employees in such coverage amounts as
required by law and employer’s liability insurance in an amount of at least Five Hundred Thousand Dollars ($500,000.00). During the Facility Term, Entegris shall maintain all risk property insurance in an amount at least equal to the

  
 Page 38 of 50

	 	 
replacement cost of Entegris’ personal property on the Premises and any other alterations, installations, additions or improvements made to the Premises by Entegris. Said replacement cost
for Entegris property shall be clearly delineated and summarized promptly upon execution of this Agreement, at each renewal/change of said Entegris property policies, or at any other point of significant change in magnitude of Entegris properties on
Millipore Premises. During the Facility Term Entegris shall maintain comprehensive automobile liability insurance in an amount of at least Five Hundred Thousand Dollars ($500,000.00) per person and per accident for bodily injury, and of at least One
Hundred Thousand Dollars ($100,000) per accident for property damage. Millipore shall be named as an additional insured on the foregoing Entegris employer’s liability, property, and automobile liability insurances, as its interests may appear.
Certificates of insurance evidencing all such coverages and Millipore additional insured status for the foregoing and for comprehensive general liability and umbrella liability coverages shall be supplied to Millipore promptly upon execution of this
Agreement and as any policies renew or are changed. 

  

	9.4	All policies of insurance obtained by Entegris pursuant to the terms of this Lease shall be issued by insurance companies reasonably acceptable to Millipore and
authorized to do business in the Commonwealth of Massachusetts. All such policies shall provide for no less than thirty (30) days prior notice to Millipore and any mortgagee of the Premises of their commencement or cancellation. Within ten
(10) days after execution of this Agreement, Entegris shall deliver to Millipore certificates thereof. Entegris shall also deliver to Millipore each renewal certificate thereof as soon as is reasonably practicable after receiving request
therefore by any mortgage lender of Millipore and at least fifteen (15) days prior to the expiration of the policy it renews. If Entegris fails to obtain and maintain any insurance policies required to be obtained and maintained by Entegris
pursuant to Section 9.2 or 9.3 of these Lease Terms, then, after written notice to Entegris of its intention to do so and notification from Entegris of its unwillingness or inability to acquire such insurance coverages, Millipore may obtain and
maintain such insurance policies (without creating any obligation on behalf of Millipore to do so), and Entegris shall pay to Millipore the cost thereof within ten (10) days after Millipore has invoiced Entegris therefor, and until paid, such
amount shall be additional Rent. 

  

	10.	Casualty or Taking 

  

	10.1	In the event that the Premises, or more than 25% thereof, shall be taken by any public authority or for any public use, or shall be destroyed or damaged by fire or
casualty, or by the action of any public authority, and the same cannot, in Millipore’s reasonable judgment, be restored within 180 days from such taking or casualty, or if in Entegris’ reasonable judgment, such circumstance would prevent
it from continuing the conduct of its manufacturing operations at the Premises substantially in the manner contemplated under this Agreement, then this Agreement may be terminated at the election of either Millipore or Entegris. Such election shall
be made by either party, by the giving of notice to the other party within thirty (30) days following such taking or casualty. 

  
 Page 39 of 50

	10.2	If neither Millipore nor Entegris exercises said election, this Agreement shall continue in force and a just proportion of the Rent reserved, as mutually agreed between
the parties, according to the nature and extent of the damages sustained by the Premises, shall be suspended or abated until the Premises, or what may remain thereof, shall be put by Millipore in proper condition for use and otherwise restored to
its former condition or the substantial equivalent, which Millipore covenants to do with reasonable diligence to the extent permitted by the net proceeds of insurance recovered or damages awarded for such taking, destruction or damage and subject to
zoning and building laws or ordinances then in existence. “Net proceeds of insurance recovered or damages awarded” refers to the gross amount of such insurance or damages less the reasonable expenses of Millipore in connection with the
collection of the same, including without limitation, fees and expenses for legal and appraisal services. If the Premises are not so restored to its former condition or the substantial equivalent within one-hundred eighty (180) days from such
taking or casualty described at Section 10.1 above, this Agreement may be terminated by Entegris upon thirty (30) days prior written notice to Millipore but only if such restoration is not completed prior to the expiration of the 30 day
notice period. 

  

	11.	Defaults and Remedies 

  

	11.1	Events of Default. If Entegris shall default in the performance of any of its obligations to pay the Rent hereunder and if such default shall continue for thirty
(30) days after written notice from Millipore designating such default, or if within thirty (30) days after written notice from Millipore to Entegris specifying any other default or defaults and Entegris has not then commenced diligently
to correct the default or defaults so specified, then, and in either of such events, Millipore and the agents and servants of Millipore lawfully may, (in addition to and not in derogation of any remedies for any preceding breach of covenant),
immediately or at any time thereafter and after demand and notice and without process of law enter into and upon the Premises or any part thereof or mail a notice of termination addressed to Entegris, and repossess the same as Millipore’s
former estate and expel Entegris and those claiming through or under Entegris and remove its and their effects without being deemed guilty of any manner of trespass and without prejudice to any remedies which might otherwise be used for arrears of
rent or prior breach of covenant, and upon such entry or mailing as aforesaid this Agreement shall terminate, and Millipore, with notice to Entegris, may store Entegris’s effects, and those of any person claiming through or under Entegris at
the expense and risk of Entegris. 

  

	11.2	 Millipore may, but shall not be obligated to, cure, at any time, following the expiration of the applicable cure period as set forth in
Section 11.1 except in cases of emergency when no notice shall be required, any material default by Entegris 

  
 Page 40 of 50

	 	 
under these Lease Terms; and whenever Millipore so elects, all direct and reasonable costs and expenses incurred by Millipore, including reasonable attorneys’ fees, in curing a material
default shall be paid by Entegris to Millipore on demand. 

  

	12.	At all times during the Facility Term, Millipore reserves the right for its employees or contractors to enter the Premises as it determines necessary or desirable, for
purposes of (i) ensuring compliance with this Agreement, (ii) health, safety and environmental compliance, (iii) maintenance or repair as required or permitted under this Agreement, or (iii) other reasonable purposes relating to
the Premises or to any areas of its 80 Ashby Road facility other than the Premises, provided in each case that such entry into the Premises does not unreasonably interfere with Entegris’ use of the Premises. Millipore shall provide advance
notice of such entry to Entegris where reasonably practicable. 

  

	13.	Entegris shall not, without Millipore’s prior written consent, (a) assign, transfer, or encumber this Agreement or any interest therein, whether directly or
by operation of law, (b) sublet any portion of the Premises; (c) grant any license, concession or other right of occupancy or any portion of the Premises; or (d) permit the use of the Premises by any parties other than Entegris. The
foregoing provisions shall not apply to either (x) transactions with an entity into which Entegris is merged or consolidated or to which all or substantially all of its assets are transferred, or (y) transactions with any entity which
controls Entegris or is controlled by Entegris or is under common control with Entegris. 

  

	14.	Subject to the provisions of these Lease Terms, including but not limited to Section 5 hereof, Millipore covenants and warrants that upon performance by Entegris
of its obligations under these Lease Terms, Millipore will keep and maintain Entegris in exclusive, quiet, peaceable, and uninterrupted possession of the Premises during the Facility Term. 

 

	15.	Millipore shall at all times comply with all laws, orders, ordinances and other public requirements now or hereafter affecting the Premises. 

 

	16.	 Any obligation of either party to indemnify the other party pursuant to these Lease Terms or this Agreement shall be barred or limited to the extent
that failure of the Indemnified Party to give prompt notice to the Indemnifying Party of a claim giving rise to such indemnification obligation, or failure of the Indemnified Party to provide the Indemnifying Party with all reasonably necessary
assistance and cooperation in connection therewith, prejudices the position of the Indemnifying Party in providing such indemnity hereunder. The Indemnifying Party shall have sole control of the defense with respect to any such claim (including
settlement thereof). The Indemnifying Party shall keep the Indemnified Party informed at all times as to the status of the matter and the Indemnifying Party’s efforts in connection therewith. The Indemnifying Party shall not settle any such
claim whereby the settlement imposes upon the 

  
 Page 41 of 50

	 	 
Indemnified Party an obligation to take some action or refrain from doing so, without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld or delayed.

  

	17.	Neither party shall unreasonably withhold or delay its consent with respect to any matter for which such party’s consent is required or desirable under these Lease
Terms or this Agreement.

in unsuccessful Film 1 process runs where it is demonstrated that Millipore failed to adhere to the process documentation and to Entegris’s technical directions. 
 I.4. Revised Responsibilities for Regulatory & HSE Compliance 
 I.4.1
Responsibilities. 
 Current responsibilities shall be revised to reflect current operating procedures, including: Entegris has assumed full
responsibility for waste disposal in connection with waste generated by the Entegris Equipment. Millipore continues to provide spill control support to ensure prompt response to any emergency situation, however, Entegris is responsible for any
follow-up actions that are required as a result of any emergency situation. VMF 4 waste treatment costs continue to be included in VMF 4 rates. 

Entegris is solely responsible for the generation, control, compliance and reporting of chemical emissions resulting from its dedicated operations
located at the Millipore Bedford site. Millipore is responsible for the generation, control, compliance and reporting of chemical emissions from its operations. Where Entegris products are processed on Millipore Equipment, Entegris and Millipore
will work together to ensure compliance with federal, state and local regulations, and conformance with EHS self certifications programs similar to ISO 14001. Furthermore, as dedicated Entegris-owned operations may have a potential impact on the
surrounding community, Entegris agrees to continue to make reasonable commercial attempts to lessen the environmental impact of its operations at the Bedford site and to notify Millipore of any chemical spills, notices of non-compliance or
inspections. 
 I.4.2 Incident Response. 
 Entegris shall notify Millipore of all spills or releases greater than the Reportable Quantity, as defined by the State of Massachusetts and Town of Bedford, whichever is less. Entegris is responsible for
timely notification and applicable follow up of regulatory agencies, as required by law or best practice. For any spill or release, Entegris shall ensure a clean up scheme that follows all of the requirements set forth in OSHA 29 CFR 1910.120 -
Hazardous Waste Operation and Emergency Response, and the Massachusetts Contingency Plan, 310 CMR 40. In the event of a spill or release from an Entegris process requiring a clean up, Millipore shall provide Entegris with clean-up services using
Millipore Corporation’s Emergency Response Team. In the event of a spill or release from an Entegris process requiring a clean up using Millipore’s Emergency Response Team, Millipore will conduct any cleanup services with the same degree
of care it would use to respond to a spill or release from a Millipore process and shall be compensated by Entegris at the rates set forth on Annex I, subject to adjustments pursuant to Section 7.3; provided, that Entegris will compensate
Millipore for at least 4 hours in the event of any such incident. 

  
 Page 48 of 50

 Entegris shall also compensate Millipore for all reasonable and customary costs associated with engaging
professional consulting services, as deemed appropriate by Millipore’s corporate EHS department and approved by Entegris’ corporate EHS department (such approval not to be unreasonably withheld or delayed, provided that if Millipore
reasonably deems the need for such consulting services urgent, such as an emergency response, and cannot reach an Entegris representative in a timely manner after diligent efforts to obtain Entegris’ approval, Millipore may proceed on a limited
basis to address such urgent situation without Entegris’ prior approval but shall notify Entegris promptly) as a result of the aforementioned spills or releases. Entegris shall also reimburse Millipore for all supplies consumed during the
response event. Entegris shall be responsible for appropriate disposal of wastes associated with any clean-up. 
 Entegris may also contract
with a third party that meets the requirements of OSHA 29 CFR 1910.120 - Hazardous Waste Operation and Emergency Response in lieu of using Millipore’s Emergency Response Team. 
 I.4.3 Equipment Operability and Risk Mitigation. 
 Entegris shall perform an initial
process hazard analysis (hazard evaluation), and proactively manage any subsequent changes, on any process or equipment (“Processes”) proposed for installation or use on Millipore managed property. The process hazard analysis shall be
completed with current process safety information and be reasonable with respect to the complexity of the Processes and shall identify, evaluate, and mitigate hazards involved in the Processes. Entegris shall conduct and implement the process hazard
analysis and a management of change procedure in a manner consistent with OSHA 29 CFR 1910.119 - Process Safety Management and in conjunction and consultation with Millipore’s EHS staff. Entegris shall implement all reasonable corrective
actions or improvements identified by the process hazard analysis in a timely manner and at its sole expense, in all cases in accordance with applicable regulatory and reasonable Millipore requirements, unless such corrective actions are facility
related, in which case such actions will be at the expense of Millipore to the extent not caused by Entegris. Copies of the process hazard analysis, corrective actions and implementation schedules shall be provided to Millipore promptly upon
availability. Furthermore, all applicable process safety information will be updated with any change to the process not considered a replacement in kind. 
 I.5. Entegris Option to Assume Supply Chain Responsibilities 

I.5.1. During the Facility Term, upon six months prior notice to Millipore, Entegris shall have the option to assume
responsibility for planning and procurement for all raw materials used in the manufacture of UPE Membranes and Treated Other Entegris Membranes. If Entegris assumes this responsibility, Entegris shall be accountable for un-utilized machine time
occurring as a result of raw material availability if Millipore cannot utilize that machine time for any 

  
 Page 49 of 50

 
alternative membranes. After the Facility Term, Entegris will have all, and Millipore will have no, responsibility for planning and procurement of any raw materials (other than with respect to
VMF4) unless the parties otherwise agree in writing. 
 I.5.2. Notwithstanding the exercise by Entegris of the option in
I.5.1, Entegris shall continue to be entitled to contract with Millipore for incoming quality control services. 
 I.6.
Resolution of Technical Issues. 
 I.6.1. In the event of chronic low yielding runs, Entegris can issue a
corrective action request. This request would result in a inter-company meeting(s) to develop a mutually agreed upon corrective action plan within two weeks of the issuance of the request. 

I.6.2. Millipore will support this activity with at least one mutually agreed upon representative (usually the Production
Supervisor and / or the Millipore Product Owner). 
 I.6.3. In the event that this vehicle is unsuccessful in resolving
the issue, the corrective action team will be supported by additional mutually agreed upon representatives with special expertise from both/either Millipore and Entegris. The cost of Millipore support for this “above and beyond” technical
support will be at the technical support rate established in accordance with Section 7.3 of the Agreement.
