74

terminated in accordance with its terms or expires without the consummation of the Versum Merger, any such ratios or tests shall be calculated on a Pro Forma Basis assuming that the Versum Merger and the other transactions in connection therewith (including any incurrence (including by way of assumption) of any Indebtedness in connection therewith, including any Incremental Loans, any Permitted Versum Existing Credit Agreement Indebtedness (solely for this purpose, assuming that the aggregate amount of the “Revolving Commitments” under, and as defined in, the Versum Existing Credit Agreement shall have been funded) and/or any Permitted Versum Existing Notes) have been consummated.

PRIORITIES AND AGREEMENTS WITH RESPECT TO SHARED COLLATERAL

SECTION 2.01 Priority of Claims.

(a) Anything contained herein or in any of the Pari Documents to the contrary notwithstanding (but subject to Sections 2.01(b) and 2.11(b)), if an Event of Default has occurred and is continuing and (i) the Applicable Representative or any Pari Secured Party is taking action to enforce rights in respect of any Shared Collateral, (ii) any distribution (including any adequate protection payment) is made in respect of any Shared Collateral in any Insolvency or Liquidation Proceeding of any Grantor or (iii) any Pari Secured Party receives any payment pursuant to any intercreditor agreement (other than this Agreement) with respect to any Shared Collateral, THEN (A) the proceeds of any sale, other disposition, collection or other liquidation of any Shared Collateral received by any Pari Secured Party on account of such enforcement of rights, (B) the proceeds of any such distribution and (C) any payment received by the Applicable Representative or any Pari Secured Party pursuant to any such intercreditor agreement with respect to such Shared Collateral (subject, in the case of any such proceeds, distribution or payment, to the sentence immediately following clause (iii) below) (all such proceeds, distributions and payments described in the foregoing clauses (A) through (C) being collectively referred to as “Proceeds”) shall, in each case, be applied by the Applicable Representative in the following order:

(i) FIRST, to the payment of all amounts owing to each Representative (in its capacity as such) secured by such Shared Collateral, including all reasonable costs and expenses incurred by each such Representative (in its capacity as such) in connection with such sale, other disposition, collection or liquidation or otherwise in connection with this Agreement, any other Pari Document or any of the Pari Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, and any other reasonable costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Pari Document and all fees and indemnities owing to such Representatives, ratably to each such Representative in accordance with the amounts payable to it pursuant to this clause FIRST;

(ii) SECOND, subject to Sections 2.01(b) and 2.11(b), to the extent Proceeds remain after the application pursuant to preceding clause (i), to each Representative for the payment in full of the other Pari Obligations of each Series secured by such Shared Collateral and, if the amount of such Proceeds are insufficient to pay in full the Pari Obligations of each Series so secured, then such Proceeds shall be allocated among the Representatives of each Series secured by such Shared Collateral pro rata according to the amounts of such Pari Obligations owing to each Representative and the other Pari Secured Parties of such Series for distribution by such Representative in accordance with the applicable Pari Documents; and

9

(iii) THIRD, any balance of such Proceeds remaining after the application pursuant to preceding clauses (i) and (ii), to the Grantors, their successors or assigns, or to whomever may be lawfully entitled to receive the same.

If, despite the provisions of this Section 2.01(a), any Pari Secured Party shall receive any payment or other recovery in excess of its portion of payments on account of the Pari Obligations to which it is then entitled in accordance with this Section 2.01(a), such Pari Secured Party shall hold such payment or recovery in trust for the benefit of all Pari Secured Parties and shall promptly transfer such payment or recovery to the Applicable Representative for distribution in accordance with this Section 2.01(a).

(b) (i) Notwithstanding the foregoing, with respect to any Shared Collateral in which a third party (other than a Pari Secured Party) has a lien or security interest that is junior in priority to the security interest of any Series of Pari Obligations but senior (as determined by appropriate legal proceedings in the case of any dispute) to the security interest of the other Series of Pari Obligations (such third party an “Intervening Creditor”), the value of any Shared Collateral or Proceeds that are allocated to such Intervening Creditor shall be deducted on a ratable basis solely from the Shared Collateral or Proceeds to be distributed in respect of the Series of Pari Obligations with respect to which such Impairment exists.

(ii) In furtherance of the foregoing and without limiting the provisions of Section 2.03, it is the intention of the Pari Secured Parties of each Series that the holders of Pari Obligations of such Series (and not the Pari Secured Parties of the other Series) (A) bear the risk of any determination by a court of competent jurisdiction that (x) any of the Pari Obligations of such Series are unenforceable under applicable law or are subordinated to any other obligations (other than the other Series of Pari Obligations), (y) any of the Pari Obligations of such Series do not have a valid and perfected security interest in any of the Collateral securing the other Series of Pari Obligations and/or (z) any intervening security interest exists securing any other obligations (other than the other Series of Pari Obligations) on a basis ranking prior to the security interest of such Series of Pari Obligations but junior to the security interest of the other Series of Pari Obligations and (B) not take into account for purposes of this Agreement the existence of any Collateral for any other Series of Pari Obligations that is not Shared Collateral (any such condition referred to in the foregoing clauses (A) or (B) with respect to any Series of Pari Obligations, an “Impairment” of such Series); provided that the existence of a maximum claim with respect to any real property subject to a mortgage that applies to all Pari Obligations shall not be deemed to be an Impairment of any Series of Pari Obligations. In the event of any Impairment with respect to any Series of Pari Obligations, the results of such Impairment shall be borne solely by the holders of such Series of Pari Obligations, and the rights of the holders of such Series of Pari Obligations

10

(including, without limitation, the right to receive distributions in respect of such Series of Pari Obligations pursuant to Section 2.01(a)) set forth herein shall be modified to the extent necessary so that the effects of such Impairment are borne solely by the holders of the Series of such Pari Obligations subject to such Impairment. Additionally, in the event the Pari Obligations of any Series are modified pursuant to applicable law (including, without limitation, pursuant to Section 1129 of the Bankruptcy Code), any reference to such Pari Obligations or the Pari Documents governing such Pari Obligations shall refer to such obligations or such documents as so modified.

(c) It is acknowledged that the Pari Obligations of any Series may, subject to the limitations set forth in the then-existing Pari Documents and subject to any limitations set forth in this Agreement, be increased, extended, renewed or otherwise amended or modified from time to time, all without affecting the priorities set forth in Section 2.01(a) or the provisions of this Agreement defining the relative rights of the Pari Secured Parties of any Series. It is further acknowledged that a portion of the Pari Obligations of each Series represents, or may in the future represent, debt that is revolving in nature and that the amount thereof that may be outstanding at any time or from time to time may be increased or reduced and subsequently re-borrowed, all without affecting the priorities set forth in Section 2.01(a) or the provisions of this Agreement defining the relative rights of the Pari Secured Parties of such Series.

(d) Notwithstanding the date, time, method, manner or order of grant, attachment or perfection of any Liens securing any Series of Pari Obligations granted on the Shared Collateral and notwithstanding any provision of the UCC, or any other applicable law or the Pari Documents or any defect or deficiencies in the Liens securing the Pari Obligations of any Series or any other circumstance whatsoever (but, in each case, subject to Sections 2.01(b) and 2.11(b)), each Pari Secured Party hereby agrees that the Liens securing each Series of Pari Obligations on any Shared Collateral shall in all cases be of equal priority.

SECTION 2.02 Actions with Respect to Shared Collateral; Prohibition on Contesting Liens.

11

Shared Collateral), whether under any Pari Collateral Document (other than the Pari Collateral Documents applicable to the Applicable Representative), applicable law or otherwise, it being agreed that only the Applicable Representative (or any Person authorized by it), acting in accordance with the Pari Collateral Documents applicable to it, shall be entitled to take any such actions or exercise any remedies with respect to such Shared Collateral at such time.

(b) Without limiting the provisions of Section 4.02, the Non-Applicable Representative hereby appoints the Applicable Representative as its agent and authorizes the Applicable Representative to exercise any and all remedies under each Pari Collateral Document with respect to Shared Collateral and to execute releases in connection therewith.

(c) Notwithstanding the equal priority of the Liens securing each Series of Pari Obligations granted on the Shared Collateral, the Applicable Representative may deal with the Shared Collateral as if such Applicable Representative had a senior and exclusive Lien on such Shared Collateral (subject, however, to Section 2.01). Neither the Non-Applicable Representative nor any Non-Applicable Secured Party will contest, protest or object to any foreclosure proceeding or action brought by the Applicable Representative or the Applicable Secured Parties or any other exercise by the Applicable Representative or the Applicable Secured Parties of any rights and remedies relating to the Shared Collateral. The foregoing shall not be construed to limit the rights and priorities of any Pari Secured Party or any Representative with respect to any Collateral not constituting Shared Collateral.

SECTION 2.03 No Interference; Payment Over; Exculpatory Provisions.

(a) Each Pari Secured Party agrees that (i) it will not (and hereby waives any right to) contest or support any other Person in contesting in any proceeding (including any Insolvency or Liquidation Proceeding) the validity or enforceability of any Pari Obligations of any Series or any Pari Collateral Document or the validity, attachment, perfection or priority of any Lien under any Pari Collateral Document or the validity or enforceability of the priorities, rights or duties established by or other provisions of this Agreement; provided that nothing in this Agreement shall be construed to prevent or impair (A) the rights of any Pari Secured Party from contesting the validity or enforceability of any Pari Obligations constituting unmatured interest or the validity of any Lien relating thereto pursuant to Section 502(b)(2) of the Bankruptcy Code, (ii) it will not take or cause to be taken any action the purpose or intent of which is, or could be, to interfere, hinder or delay, in any manner, whether by judicial proceedings or otherwise, any sale, transfer or other disposition of the Collateral by the Applicable Representative, (iii) except as provided in Section 2.02 and subject to the rights of the Applicable Secured Parties under their Pari Documents, it shall have no right to and shall not otherwise (A) direct the Applicable Representative or any other Pari Secured Party to exercise any right, remedy or power with respect to any Shared Collateral (including pursuant to any other intercreditor agreement) or (B) consent to, or object to, the exercise by, or any forbearance from exercising by, the Applicable Representative or any other Pari Secured Party represented thereby of any right, remedy or power with respect to any Shared Collateral, (iv) it will not institute any suit or assert in any suit, Insolvency or Liquidation Proceeding or other proceeding any claim against the Applicable Representative or any Pari Secured Party represented thereby seeking

12

damages from or other relief by way of specific performance, instructions or otherwise with respect to any Shared Collateral and (v) it will not attempt, directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of this Agreement; provided that nothing in this Agreement shall be construed to prevent or impair the rights of any of the Applicable Representative or any other Pari Secured Party to enforce this Agreement, including, without limitation, Section 2.01(b).

(b) Each Pari Secured Party hereby agrees that if, at any time prior to the Discharge of each of the Pari Obligations, it shall obtain possession of any Shared Collateral or shall realize any proceeds or payment in respect of any Shared Collateral pursuant to any Pari Collateral Document, by the exercise of any rights available to it under applicable law or in any Insolvency or Liquidation Proceeding or through any other exercise of remedies (including pursuant to any intercreditor agreement), then it shall hold such Shared Collateral, proceeds or payment in trust for the other Pari Secured Parties having a security interest in such Shared Collateral and promptly transfer any such Shared Collateral, proceeds or payment, as the case may be, to the Applicable Representative, to be distributed by such Applicable Representative in accordance with the provisions of

Section 2.01(a).

(c) None of the Applicable Representative or any other Pari Secured Party shall be liable for any action taken or omitted to be taken by the Applicable Representative or any other Pari Secured Party with respect to any Shared Collateral in accordance with the provisions of this Agreement.

SECTION 2.04 Automatic Release of Liens.

(a) If, at any time, any Shared Collateral (including any Equity Interests in any Person) is sold or otherwise disposed of to a third party, in each case, in connection with any enforcement of rights by the Applicable Representative in accordance with the provisions of this Agreement, then (whether or not any Insolvency or Liquidation Proceeding is pending at the time) the Liens in favor of the other Representative for the benefit of the other Series of Pari Secured Parties (or in favor of such other Pari Secured Parties if directly secured by such Liens) upon such Shared Collateral (including, in the case of a sale or other disposition of Equity Interests in any Person, any property and assets of such Person constituting Shared Collateral) will automatically be released and discharged as and when, but only to the extent, such Liens of the Applicable Representative on such Shared Collateral are released and discharged; provided that (i) the liens in favor of each Representative for the benefit of its Series of Pari Secured Parties secured by such Shared Collateral shall attach to any Proceeds of such sale or other disposition (including, in the case of a sale or other disposition of Equity Interests in any Person, Proceeds attributable to any property and assets of such Person constituting Shared Collateral) with the same priority as is provided in Section 2.02(c), and any such Liens shall remain thereon subject to the terms of this Agreement until the application thereof pursuant to Section 2.01 and (ii) any Proceeds of any Shared Collateral realized therefrom shall be applied pursuant to Section 2.01. If, in connection with any enforcement of rights by the Applicable Representative in accordance with the provisions of this Agreement, the Applicable Representative releases any Subsidiary of Entegris from its guarantee of the Pari Obligations of the Series represented by the Applicable Representative prior to a Discharge of such Series of Pari Obligations, then such Subsidiary will automatically be released from its guarantee of the other Series of the Pari Obligations as and when, but only to the extent, its guarantee of the Pari Obligations of the Series represented by the Applicable Representative is released.

13

(b) Without limiting the rights of the Applicable Representative under Section 4.02, each Representative agrees to execute and deliver (at the sole cost and expense of the Grantors) all such authorizations and other instruments as shall reasonably be requested by the Applicable Representative to evidence and confirm any release of Shared Collateral or guarantees provided for in this Section 2.04.

SECTION 2.05 Certain Agreements with Respect to Bankruptcy or Insolvency Proceedings.

(a) This Agreement shall continue in full force and effect notwithstanding the commencement of any Insolvency or Liquidation Proceeding. The parties hereto acknowledge that the provisions of this Agreement are intended to be enforceable as contemplated by Section 510(a) of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law.

(b) If any Grantor shall become subject to a case under Bankruptcy Law (a “Bankruptcy Case”) and shall, as debtor(s)-in-possession, move for approval of financing (“DIP Financing”) to be provided by one or more lenders (the “DIP Lenders”) under Section 364 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law or the use of cash collateral under Section 363 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law, each Non-Applicable Secured Party agrees that it will not raise any objection to any such financing or to the Liens on the Shared Collateral securing the same (“DIP Financing Liens”) or to any use of cash collateral that constitutes Shared Collateral, unless the Applicable Representative shall then oppose or object to such DIP Financing or such DIP Financing Liens or use of cash collateral (and (i) to the extent that such DIP Financing Liens are senior to the Liens on any such Shared Collateral for the benefit of any Applicable Secured Parties, each Non-Applicable Secured Party will subordinate its Liens with respect to such Shared Collateral on the same terms as the Liens of such Applicable Secured Parties (other than any Liens of any Pari Secured Parties constituting DIP Financing Liens) are subordinated thereto, and (ii) to the extent that such DIP Financing Liens rank pari passu with the Liens on any such Shared Collateral granted to secure the Pari Obligations of the Applicable Secured Parties, each Non-Applicable Secured Party will confirm the priorities with respect to such Shared Collateral as set forth herein), in each case so long as (A) the Pari Secured Parties of each Series retain the benefit of their Liens on all such Shared Collateral pledged to the DIP Lenders, including proceeds thereof arising after the commencement of such Bankruptcy Case, with the same priority vis-à-vis all the other Pari Secured Parties (other than any Liens of the Pari Secured Parties constituting DIP Financing Liens) as existed prior to the commencement of such Bankruptcy Case, (B) the Pari Secured Parties of each Series are granted Liens on any additional collateral pledged to any Pari Secured Parties as adequate protection or otherwise in connection with such DIP Financing or use of cash collateral, with the same priority vis-à-vis the Pari Secured Parties as set forth in this Agreement (other than any Liens of any Pari Secured Parties constituting DIP Financing Liens), (C) if any amount of such DIP Financing or cash collateral is applied

14

to repay any of the Pari Obligations, such amount is applied pursuant to Section 2.01(a) and (D) if any Pari Secured Parties are granted adequate protection with respect to the Pari Obligations, including in the form of periodic payments, in connection with such DIP Financing and/or use of cash collateral, the proceeds of such adequate protection are applied pursuant to Section 2.01(a); provided that the Pari Secured Parties of each Series shall have a right to object to the grant of a Lien to secure the DIP Financing over any Collateral subject to Liens in favor of the Pari Secured Parties of such Series or its Representative that shall not constitute Shared Collateral (unless such Collateral fails to constitute Shared Collateral because the Lien in respect thereof constitutes a Declined Lien with respect to such Pari Secured Parties or their Representative); provided, further, that the Pari Secured Parties receiving adequate protection shall not oppose or object to any other Pari Secured Party receiving adequate protection comparable to any adequate protection granted to such Pari Secured Parties in connection with a DIP Financing or use of cash collateral.

(c) If any Pari Secured Party is granted adequate protection (i) in the form of Liens on any additional collateral, then each other Pari Secured Party shall be entitled to seek, and each Pari Secured Party will consent and not oppose or object to, adequate protection in the form of Liens on such additional collateral with the same priority vis-à-vis the Pari Secured Parties as set forth in this Agreement, (ii) in the form of a superpriority or other administrative claim, then each other Pari Secured Party shall be entitled to seek, and each Pari Secured Party will consent and not oppose or object to, adequate protection in the form of a pari passu superpriority or administrative claim or (iii) in the form of periodic or other cash payments, then the proceeds of such adequate protection must be applied to all Pari Obligations pursuant to Section 2.01.

SECTION 2.06 Reinstatement. In the event that any of the Pari Obligations shall be paid in full and such payment or any part thereof shall subsequently, for whatever reason (including an order or judgment for disgorgement of a preference under Title 11 of the Bankruptcy Code, or any similar law, or the settlement of any claim in respect thereof), be required to be returned or repaid, the terms and conditions of this Agreement shall be fully applicable thereto until all such Pari Obligations shall again have been paid in full in cash.

SECTION 2.07 Insurance. As among the Pari Secured Parties, the Applicable Representative shall have the right, but no obligation, to adjust or settle any insurance policy or claim covering or constituting Shared Collateral in the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding affecting the Shared Collateral. To the extent any Representative receives proceeds of such insurance policy and such proceeds are not permitted or required to be returned to any Grantor under the applicable Pari Documents, such proceeds shall be turned over to the Applicable Representative for application as provided in Section 2.01.

SECTION 2.08 Refinancings. The Pari Obligations of any Series may, subject to Section 5.14, be Refinanced with Refinancing Indebtedness under a Replacement Entegris Credit Agreement or a Replacement Versum Credit Agreement, as the case may be, in each case, without notice to, or the consent (except to the extent a consent is otherwise required to permit such Refinancing under any Pari Document) of, any Pari Secured Party of the other Series, all without affecting the priorities provided for herein or the other provisions hereof; provided that the Replacement Representative of the holders of any such Refinancing Indebtedness shall have executed a Joinder Agreement on behalf of the holders of such Refinancing Indebtedness.

15

SECTION 2.09 Gratuitous Bailee/Agent for Perfection.

(a) The Possessory Collateral in the possession of the Non-Applicable Representative (or its agents or bailees, other than the other Representative) shall be delivered by the Non-Applicable Representative to the Applicable Representative. If at any time the Person constituting the Applicable Representative ceases to be the Applicable Representative, such former Applicable Representative shall deliver the Possessory Collateral in its possession (or in the possession of its agents or bailees, other than the other Representative) (if any), together with any necessary endorsements (which endorsement shall be without recourse and without any representation or warranty), to the incoming Applicable Representative. The former Applicable Representative further agrees to take all other action reasonably requested by the incoming Applicable Representative, at the expense of the Grantors, in connection with the incoming Applicable Representative obtaining a first-priority security interest in the Shared Collateral.

(b) Each Representative agrees to hold any Possessory Collateral from time to time in its possession (or in the possession of its agents or bailees, other than the other Representative) as gratuitous bailee for the benefit of each other Pari Secured Party (such bailment being intended, among other things, to satisfy the requirements of Sections 8-106(d)(3), 8-301(a)(2) and 9-313(c) of the UCC), solely for the purpose of perfecting the security interest granted in such Possessory Collateral, if any, pursuant to the applicable Pari Collateral Documents, in each case, subject to the terms and conditions of this Section 2.09. Each Representative agrees to hold any Control Collateral from time to time under its control (or under the control of its agents or bailees, other than the other Representative) as gratuitous agent for the benefit of each other Pari Secured Party (such agency being intended, among other things, to satisfy the requirements of 9-104, 9-105, 9-106, 9-107 or 8-106 of the UCC), solely for the purpose of perfecting the security interest granted in such Control Collateral, if any, pursuant to the applicable Pari Collateral Documents, in each case, subject to the terms and conditions of this Section 2.09.

(c) Neither Representative shall have any obligation whatsoever to any Pari Secured Party to ensure that the Possessory Collateral or the Control Collateral is genuine or owned by any of the Grantors or to preserve rights or benefits of any Person except as expressly set forth in this Section 2.09. The duties or responsibilities of each Representative under this Section 2.09 shall be limited solely to holding any Possessory Collateral or Control Collateral in its possession or control (or in possession or control of its agents or bailees, other than the other Representative) as gratuitous bailee and gratuitous agent in accordance with this Section 2.09 and delivering the Possessory Collateral as provided in Section 2.09(a).

16

(d) None of the Representatives or any of the Pari Secured Parties shall have, by reason of the Pari Documents, this Agreement or any other document, a fiduciary relationship in respect of the other Representatives or any other Pari Secured Party, and each Representative and each Pari Secured Party hereby waives and releases the other Representatives and Pari Secured Parties from all claims and liabilities arising pursuant to any Representative’s role under this Section 2.09 as gratuitous bailee or gratuitous agent with respect to any Possessory Collateral or Control Collateral in its possession or control (or in the possession or control of its agents or bailees, other than the other Representative).

SECTION 2.10 Amendments to Pari Collateral Documents.

(a) Without the prior written consent of the other Representative, each Representative agrees that no Pari Collateral Document may be amended, supplemented or otherwise modified or entered into to the extent such amendment, supplement or modification, or the terms of any new Pari Collateral Document, would be prohibited by, or would require any Grantor to act or refrain from acting in a manner that would violate, any of the terms of this Agreement.

(b) In determining whether an amendment to any Pari Collateral Document is permitted by this Section 2.10, each Representative may conclusively rely on an officer’s certificate of Entegris stating that such amendment is permitted by this Section 2.10.

SECTION 2.11 Similar Liens and Agreements.

(a) Subject to Section 2.11(b), the parties hereto agree that it is their intention that the Collateral be substantially identical for all Pari Secured Parties; provided that this provision will not be violated with respect to any particular Series if for any reason the Representative for that Series expressly declines to accept a Lien on any asset or property (any such declined Lien with respect to a particular Series, a “Declined Lien”). In furtherance of, but subject to, the foregoing, the parties hereto agree, subject to the other provisions of this Agreement, upon request by either Representative, to cooperate in good faith (and to direct their counsel to cooperate in good faith) from time to time in order to determine the specific items included in the Shared Collateral and the steps taken to perfect their respective Liens thereon and the identity of the respective parties obligated under the Pari Documents.

(b) Notwithstanding anything in this Agreement or any Pari Documents to the contrary, Collateral consisting of cash, cash equivalents and Deposit Account balances pledged to secure reimbursement obligations in respect of any Letter of Credit shall be applied as specified in the Entegris Credit Agreement or the Versum Credit Agreement, as applicable, and, other than for purposes of Section 2.09, will not constitute Shared Collateral, it being understood and agreed that this Agreement shall not restrict the rights of any Pari Secured Party to pursue enforcement rights or exercise of remedies with respect thereto.

ARTICLE III.

EXISTENCE AND AMOUNTS OF LIENS AND OBLIGATIONS

Whenever the Applicable Representative shall be required, in connection with the exercise of its rights or the performance of its obligations hereunder, to determine the existence or amount of any Pari Obligations of any Series, or the Shared Collateral subject to any Lien securing the Pari Obligations of any Series, it may request that such information be

17

furnished to it in writing by the Non-Applicable Representative and shall be entitled to make such determination or not make any determination on the basis of the information so furnished; provided, however, that if the Non-Applicable Representative shall fail or refuse reasonably promptly to provide the requested information, the Applicable Representative shall be entitled to make any such determination or not make any determination by such method as it may, in the exercise of its good faith judgment, determine, including by reliance upon a certificate of Entegris. The Applicable Representative may rely conclusively, and shall be fully protected in so relying, on any determination made by it in accordance with the provisions of the preceding sentence (or as otherwise directed by a court of competent jurisdiction) and shall have no liability to any Grantor, any Pari Secured Party or any other Person as a result of such determination.

ARTICLE IV.

THE APPLICABLE REPRESENTATIVE

SECTION 4.01 Authority.

(a) Notwithstanding any other provision of this Agreement, nothing herein shall be construed to impose any fiduciary or other duty on the Applicable Representative to any Non-Applicable Secured Party or give any Non-Applicable Secured Party the right to direct the Applicable Representative, except that the Applicable Representative shall be obligated to distribute Proceeds of any Shared Collateral in accordance with Section 2.01.

(b) In furtherance of the foregoing, each Non-Applicable Secured Party acknowledges and agrees that the Applicable Representative shall be entitled, for the benefit of the Pari Secured Parties, to sell, transfer or otherwise dispose of or deal with any Shared Collateral as provided herein and in the applicable Pari Collateral Documents, without regard to any rights to which the Non-Applicable Secured Parties would otherwise be entitled as a result of the Pari Obligations held by such Non-Applicable Secured Parties. Without limiting the foregoing, each Pari Secured Party agrees that none of the Applicable Representative or any other Pari Secured Party shall have any duty or obligation first to marshal or realize upon any type of Shared Collateral (or any other Collateral securing any of the Pari Obligations), or to sell, dispose of or otherwise liquidate all or any portion of such Shared Collateral (or any other Collateral securing any Pari Obligations), in any manner that would maximize the return to the Non-Applicable Secured Parties, notwithstanding that the order and timing of any such realization, sale, disposition or liquidation may affect the amount of proceeds actually received by the Non-Applicable Secured Parties from such realization, sale, disposition or liquidation. Each of the Pari Secured Parties of a particular Series waives any claim it may now or hereafter have against the Representative of the other Series of Pari Obligations or any other Pari Secured Party of such other Series arising out of (i) any actions that such Representative or any Pari Secured Party represented by such Representative take or omit to take (including, actions with respect to the creation, perfection or continuation of Liens on any Collateral, actions with respect to the foreclosure upon, sale, release or depreciation of, or failure to realize upon, any of the Collateral and actions with respect to the collection of any claim for all or any part of the Pari Obligations from any account debtor, guarantor or any other party) in accordance with the Pari Collateral Documents or any other agreement related thereto or in connection with the collection of the Pari Obligations or the

18

valuation, use, protection or release of any security for the Pari Obligations; provided that nothing in this clause (i) shall be construed to prevent or impair the rights of either Representative to enforce this Agreement, (ii) any election by the Applicable Representative or any holders of Pari Obligations, in any proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b) of the Bankruptcy Code or (iii) subject to Section 2.05, any borrowing, or grant of a security interest or administrative expense priority under Section 364 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law, by Entegris or any of its Subsidiaries, as debtor-in-possession. Notwithstanding any other provision of this Agreement, the Applicable Representative shall not accept any Shared Collateral in full or partial satisfaction of any Pari Obligations pursuant to Section 9-620 of the UCC without the consent of the other Representative.

SECTION 4.02 Power-of-Attorney. The Non-Applicable Representative, for itself and on behalf of the Non-Applicable Secured Parties, hereby irrevocably appoints the Applicable Representative and any officer or agent of the Applicable Representative, which appointment is coupled with an interest with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Non-Applicable Representative or any Non-Applicable Secured Party, to take any and all appropriate action and to execute any and all documents and instruments that may be necessary to accomplish the purposes of this Agreement, including the exercise of any and all remedies under each Pari Collateral Document with respect to Shared Collateral and the execution of releases in connection therewith.

SECTION 5.01 Integration/Conflicts. This Agreement, together with the other Pari Documents, represents the entire agreement of each of the Grantors and the Pari Secured Parties with respect to the subject matter hereof and supersedes any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. There are no promises, undertakings, representations or warranties by either Representative or any Pari Secured Party relative to the subject matter hereof not expressly set forth or referred to herein or therein. In the event of any conflict between the provisions of this Agreement and the provisions of the other Pari Documents, the provisions of this Agreement shall govern and control.

SECTION 5.02 Effectiveness; Continuing Nature of this Agreement; Severability. This Agreement shall become effective when executed and delivered by the parties identified on the signature pages hereto. This is a continuing agreement, and the Pari Secured Parties of either Series may continue, at any time and without notice to any Pari Secured Party of the other Series, to extend credit and other financial accommodations and lend monies to or for the benefit of Entegris or any other Grantor constituting Pari Obligations in reliance hereon. Each Representative, on behalf of itself and the Pari Secured Parties represented by it, hereby waives any right it may have under applicable law to revoke this Agreement or any of the provisions of this Agreement. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof,

19

and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties hereto shall endeavor in good-faith negotiations to replace any invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to those of the invalid, illegal or unenforceable provisions. All references to Entegris or any other Grantor shall include Entegris or such Grantor as debtor and debtor in possession and any receiver, trustee or similar person for Entegris or any other Grantor (as the case may be) in any Insolvency or Liquidation Proceeding. This Agreement shall terminate and be of no further force and effect with respect to any Representative or the Pari Secured Parties represented by such Representative and their Pari Obligations on the date on which no Pari Obligations of such Pari Secured Parties are any longer secured by, or required to be secured by, any of the Collateral pursuant to the terms of the applicable Pari Documents, subject to the rights of the Pari Secured Parties under Section 2.06; provided, however, that such termination shall not relieve any such party of its obligations incurred hereunder prior to the date of such termination.

SECTION 5.03 Amendments; Waivers.

(a) No amendment, modification or waiver of any of the provisions of this Agreement may be made unless the same shall be in writing signed on behalf of each party hereto or its authorized agent and each waiver, if any, shall be a waiver only with respect to the specific instance involved and shall in no way impair the rights of the parties making such waiver or the obligations of the other parties to such party in any other respect or at any other time. Notwithstanding the foregoing, Entegris and the other Grantors shall not have any right to consent to or approve any amendment, modification or waiver of any provision of this Agreement except to the extent their rights are directly and adversely affected.

(b) Notwithstanding the foregoing, without the consent of any Pari Secured Party, any Representative may become a party hereto by execution and delivery of a Joinder Agreement in accordance with Section 5.14 and upon such execution and delivery, such Replacement Representative and the Pari Secured Parties and Pari Obligations of the Series for which such Replacement Representative is acting shall be subject to the terms hereof.

The Representative and the other Pari Secured Parties of each Series shall have no duty to advise the Representative or Pari Secured Parties of the other Series of information known to it or them regarding such condition or any such circumstances or otherwise. In the event the Representative or any of the other Pari Secured Parties, in its or their sole discretion, undertakes at any time or from time to time to provide any such information to the Representative or Pari Secured Parties of the other Series, it or they shall be under no obligation:

21

(d) waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or any Pari Collateral Document in any court referred to in Section 5.05(a) (and irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court);

The parties hereto further agree that, notwithstanding any failure to take the actions required by the immediately preceding sentence, each Person that becomes a Grantor at any time (and any security granted by any such Person) shall be subject to the provisions hereof as fully as if same constituted a Grantor as of the date hereof and had complied with the requirements of the immediately preceding sentence.
