(a) No Party nor any Subsidiary thereof shall be liable to the other Party or any Subsidiary of the other Party based upon, arising out of or resulting from any Contract, arrangement, course of dealing or understanding between or among it and the other Party existing at or prior to the Separation Time (other than as set forth on any Ancillary Agreement, any Continuing Arrangements, any Third Party Agreements, as set forth in Section 2.4 or Section 6.1(b) or pursuant to any other Contract entered into in connection herewith or in order to consummate the transactions contemplated hereby or thereby) and each Party hereby terminates any and all Contracts (including any provisions thereof which purport to survive termination), arrangements, courses of dealing or understandings between or among it and the other Party effective as of the Separation Time (other than as set forth on any Ancillary Agreement, any Continuing Arrangements, any Third Party Agreements, as set forth in Section 2.4 or Section 6.1(b) or pursuant to any Contract entered into in connection herewith or in order to consummate the transactions contemplated hereby or thereby); provided , however , that with respect to any Contract, arrangement, course of dealing or understanding between or among the Parties or any Subsidiaries thereof discovered after the Separation Time, the Parties agree that such Contract, arrangement, course of dealing or understanding shall nonetheless be deemed terminated as of the Separation Time with the only liability of the Parties in respect thereof to be the obligations incurred between the Parties pursuant to such Contract, arrangement, course of dealing or understanding between the Separation Time and the time of discovery or later termination of any such Contract, arrangement, course of dealing or understanding.

(b) If any Contract, arrangement, course of dealing or understanding is terminated pursuant to Section 2.5(a) and, but for the mistake or oversight of either Party, would have been listed and is reasonably necessary for such affected Party to be able to continue to operate its businesses in substantially the same manner in which such businesses were operated prior to the Separation Time, then, at the request of such affected Party made within six (6) months following the Separation Time, the Parties shall negotiate in good faith to determine whether and to what extent (including the terms and conditions relating thereto), if any, notwithstanding such termination, such Contract, arrangement, course of dealing or understanding should continue following the Separation Time; provided , however , that any Party may determine, in its sole discretion, not to re-instate or otherwise continue any such Contract, arrangement, course of dealing or understanding.

Section 2.6 Transfers Not Effected at or Prior to the Separation Time; Transfers Deemed Effective as of the Separation Time .

(a) To the extent that any Transfers or Assumptions contemplated by this Article II shall not have been consummated at or prior to the Separation Time, the Parties shall use commercially reasonable efforts to effect such Transfers or Assumptions as promptly

22

following the Separation Time as shall be practicable. Nothing herein shall be deemed to require or constitute the Transfer of any Assets or the Assumption of any Liabilities which by their terms or operation of Law cannot be Transferred; provided , however , that the Parties and their respective Subsidiaries shall cooperate and use commercially reasonable efforts to seek to obtain, in accordance with applicable Law, any necessary Consents or Governmental Approvals for the Transfer of all Assets and Assumption of all Liabilities contemplated to be Transferred and Assumed pursuant to this Article II to the fullest extent permitted by applicable Law. In the event that any such Transfer of Assets or Assumption of Liabilities has not been consummated, from and after the Separation Time (i) the Party (or relevant member in its Group) retaining such Asset shall thereafter hold (or shall cause such member in its Group to hold) such Asset in trust for the use and benefit of the Party entitled thereto (at the expense of the Party entitled thereto) and (ii) the Party intended to Assume such Liability shall, or shall cause the applicable member of its Group to, pay or reimburse the Party retaining such Liability for all amounts paid or incurred in connection with the retention of such Liability; provided that in the event that any such Transfer of Assets or Assumption of Liabilities is not able to be completed within eighteen (18) months following the Separation Time, the Parties shall cooperate and use commercially reasonable efforts to determine the appropriate treatment (including potential disposition) of such asset or liability. To the extent the foregoing applies to any Contracts (other than Shared Contracts, which shall be governed solely by Section 2.3 ) to be assigned for which any necessary Consents or Governmental Approvals are not received prior to the Separation Time, the treatment of such Contracts shall, for the avoidance of doubt, be subject to Section 2.8 and Section 2.9 , to the extent applicable. In addition, the Party retaining such Asset or Liability (or relevant member of its Group) shall (or shall cause such member in its Group to) treat, insofar as reasonably possible and to the extent permitted by applicable Law, such Asset or Liability in the ordinary course of business in accordance with past practice and take such other actions as may be reasonably requested by the Party to which such Asset is to be Transferred or by the Party Assuming such Liability in order to place such Party, insofar as reasonably possible and to the extent permitted by applicable Law, in the same position as if such Asset or Liability had been Transferred or Assumed as contemplated hereby and so that all the benefits and burdens relating to such Asset or Liability, including possession, use, risk of loss, potential for income and gain, and dominion, control and command over such Asset or Liability, are to inure from and after the Separation Time to the relevant member or members of the Air Products Group or the Versum Group entitled to the receipt of such Asset or required to Assume such Liability. In furtherance of the foregoing, the Parties agree that, as of the Separation Time, subject to Section 2.2(c) and Section 2.9(b) , each Party shall be deemed to have acquired complete and sole beneficial ownership over all of the Assets, together with all rights, powers and privileges incident thereto, and shall be deemed to have Assumed in accordance with the terms of this Agreement all of the Liabilities, and all duties, obligations and responsibilities incident thereto, which such Party is entitled to acquire or required to Assume pursuant to the terms of this Agreement.

If and when any such Consent, Governmental Approval, release, substitution or amendment shall be obtained or such agreement, lease, license or other rights or obligations shall otherwise become assignable or able to be novated, the Other Party shall, to the fullest extent permitted by applicable Law, promptly Transfer or cause the Transfer of all rights, obligations and other Liabilities thereunder of such Other Party or any member of such Other Party’s Group to the Liable Party or to another member of the Liable Party’s Group without payment of any further consideration and the Liable Party, or another member of such Liable Party’s Group, without the payment of any further consideration, shall Assume such rights and Liabilities to the fullest extent permitted by applicable Law.

For Record Holders who own Air Products Common Stock through a broker or other nominee, their shares of Versum Common Stock will be credited to their respective accounts by such broker or nominee.

The Distribution Agent shall, as soon as practicable after the Distribution Date (a) determine the number of whole shares and fractional shares of Versum Common Stock allocable to each Record Holder, (b) aggregate all such fractional shares into whole shares and sell the whole shares obtained thereby in open market transactions at then prevailing trading prices on behalf of holders who would otherwise be entitled to fractional share interests, and (c) distribute to each such holder, or for the benefit of each such beneficial owner, such holder’s or owner’s ratable share of the net proceeds of such sale, based upon the average gross selling price per share of Versum Common Stock after making appropriate deductions for any amount required to be withheld for United States federal income tax purposes. Versum shall bear the cost of brokerage fees and transfer Taxes incurred in connection with these sales of fractional shares, which such sales shall occur as soon after the Distribution Date as practicable and as determined by the Distribution Agent. None of Air Products, Versum or the applicable Distribution Agent will guarantee any minimum sale price for the fractional shares of Versum Common Stock. Neither Air Products nor Versum will pay any interest on the proceeds from the sale of fractional shares.

In connection therewith, the Parties agree that, following the Separation Time, if either Air Products or Versum acquires knowledge of an opportunity that meets the foregoing standard with respect to more than one Party, neither party shall have any duty to communicate or offer such opportunity to the other and each may pursue or acquire such opportunity for itself, or direct such opportunity to any other Person.

(a) Direct Claims . Other than with respect to Third Party Claims, which shall be governed by Section 6.4(b) , each Air Products Indemnitee and Versum Indemnitee (each, an “ Indemnitee ”) shall notify in writing, with respect to any matter that such Indemnitee has determined has given or could give rise to a right of indemnification under this Agreement or any Ancillary Agreement, the Party which is or may be required pursuant to this Article VI or pursuant to any Ancillary Agreement to make such indemnification (the “ Indemnifying Party ”), within thirty (30)days of such determination, stating in such written notice the amount of the Indemnifiable Loss claimed, if known, and, to the extent practicable, method of computation thereof, and referring to the provisions of this Agreement in respect of which such right of indemnification is claimed by such Indemnitee or arises; provided , however , that the failure to provide such written notice within the thirty (30) day period described above shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been actually prejudiced as a result of such failure. The Indemnifying Party will have a period of thirty (30) days after receipt of a notice under this Section 6.4(a) within which to respond thereto. If the Indemnifying Party fails to respond within such period, the Liability specified in such notice from the Indemnitee shall be conclusively determined to be a Liability of the Indemnifying Party hereunder. If such Indemnifying Party responds within such period and rejects such claim in whole or in part, the disputed matter shall be resolved in accordance with Article VIII .

42

(b) Third Party Claims . If a claim or demand is made against an Indemnitee by any Person who is not a party to this Agreement (such claim, a “ Third Party Claim ”) as to which such Indemnitee is or may be entitled to indemnification pursuant to this Agreement or any Ancillary Agreement, such Indemnitee shall notify the Indemnifying Party in writing (which notice obligation may be satisfied by providing copies of all notices and documents received by the Indemnitee relating to the Third Party Claim), and in reasonable detail, of the Third Party Claim promptly (and in any event within thirty (30) days) after receipt by such Indemnitee of written notice of the Third Party Claim; provided , however , that the failure to provide notice of any such Third Party Claim pursuant to this or the preceding sentence shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been actually prejudiced as a result of such failure (except that the Indemnifying Party shall not be liable for any expenses incurred by the Indemnitee in defending such Third Party Claim during the period in which the Indemnitee failed to give such notice). Thereafter, the Indemnitee shall deliver to the Indemnifying Party, promptly (and in any event within ten (10) Business Days) after the Indemnitee’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third Party Claim. For all purposes of this Section 6.4(b) , each Party shall be deemed to have notice of the matters set forth on Schedule 1.1(98)(viii) .

(c) Other than in the case of (i) Taxes addressed in the Tax Matters Agreement, which shall be addressed as set forth therein or (ii) indemnification by a beneficiary Party of a guarantor Party pursuant to Section 2.10(c) (the defense of which shall be controlled by the beneficiary Party), the Indemnifying Party shall be entitled, if it so chooses, to assume the defense thereof, and if it does not assume the defense of such Third Party Claim, to participate in the defense of any Third Party Claim in accordance with the terms of Section 6.5 at such Indemnifying Party’s own cost and expense and by such Indemnifying Party’s own counsel, that is reasonably acceptable to the Indemnitee, within thirty (30) days of the receipt of an indemnification notice from such Indemnitee; provided , however , that the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim to the extent such Third Party Claim (x) is an allegation of a criminal violation or (y) seeks injunctive relief against the Indemnitee. In connection with the Indemnifying Party’s defense of a Third Party Claim, such Indemnitee shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, at its own expense and, in any event, shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent Information, materials and information in such Indemnitee’s possession or under such Indemnitee’s control relating thereto as are reasonably required by the Indemnifying Party; provided , however , that in the event of a conflict of interest between the Indemnifying Party and the applicable Indemnitee(s), or in the event that any Third Party Claim seeks equitable relief which would restrict or limit the future conduct of the Indemnitee’s business or operations, such Indemnitee(s) shall be entitled to retain, at the Indemnifying Party’s expense, separate counsel as required by the applicable rules of professional conduct with respect to such matter; provided , further , that if the Indemnifying Party has assumed the defense of the Third Party Claim but has specified, and continues to assert, any reservations or exceptions to such defense or to its liability therefor, then, in any such

43

case, the reasonable fees and expenses of one separate counsel for all Indemnitees shall be borne by the Indemnifying Party. The Indemnifying Party shall have the right to compromise or settle a Third Party Claim, the defense of which it shall have assumed pursuant to this Section 6.4(c) and any such settlement or compromise made or caused to be made of a Third Party Claim in accordance with this Article VI shall be binding on the Indemnitee, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise. Notwithstanding the foregoing sentence, the Indemnifying Party shall not settle, compromise or consent to the entry of judgment with respect to any such Third Party Claim without the written consent of the Indemnitee unless such settlement, compromise, consent or judgment (A) completely and unconditionally releases the Indemnitee in connection with such matter, (B) provides relief consisting solely of money damages borne by the Indemnifying Party and (C) does not involve any admission by the Indemnitee of any wrongdoing or violation of Law.

(d) Notwithstanding anything to the contrary set forth in this Section 6.4 , Air Products may elect to have exclusive authority and control over the investigation, prosecution, defense and appeal of all Actions pending at the Separation Time which relate to or arise out of the Versum Business, the Versum Assets or the Versum Liabilities if such Action also relates to the Air Products Retained Assets and Air Products Retained Liabilities and a member of the Air Products Group is also named as a target or defendant thereunder (but excluding any such Actions which solely relate to or solely arise in connection with the Versum Business, the Versum Assets or the Versum Liabilities); provided that (i) Air Products will consult with Versum on a regular basis with respect to strategy and developments with respect to any such Action, (ii) if Air Products fails to take reasonable steps necessary to defend diligently such Action, Versum may assume such defense, and Air Products will be liable for all reasonable costs or expenses paid or incurred in connection with such defense, (iii) Versum has the right to participate in (but, subject to clause (ii) above, not control) the defense of such Action, and (iv) Air Products shall not settle, compromise or consent to the entry of judgment with respect to such Action without the consent of Versum unless such settlement, compromise, consent or judgment (A) provides relief consisting solely of money damages borne by Air Products and (B) does not, in the reasonable opinion of Versum, otherwise materially adversely affect Versum. After any such compromise, settlement, or consent to entry of judgment, Air Products and Versum will agree upon a reasonable allocation to Versum and Versum will be responsible for or receive, as the case may be, Versum’s proportionate share of any such compromise, settlement, consent or judgment attributable to the Versum Business, the Versum Assets or the Versum Liabilities, including its proportionate share of the reasonable costs and expenses associated with defending same. If the Parties cannot agree on the allocation of any such Liabilities for Actions, they shall resolve the matter pursuant to the procedures set forth in Article VIII .

(e) If an Indemnifying Party fails for any reason to assume responsibility for defending a Third Party Claim within the thirty (30) day period specified in this Section 6.4 , such Indemnitee may defend such Third Party Claim at the cost and expense of the Indemnifying Party. If an Indemnifying Party has failed to assume the defense of the Third Party Claim within the time period specified in clause (c) above, it shall not be a defense to any obligation to pay any amount in respect of such Third Party Claim that the Indemnifying Party was not consulted in the defense thereof, that such Indemnifying Party’s views or opinions as to the conduct of such defense were not accepted or adopted, that such Indemnifying Party does not approve of the quality or manner of the defense thereof or that such Third Party Claim was incurred by reason of a settlement rather than by a judgment or other determination of liability.

44

(f) Except as explicitly set forth in this Agreement, or to the extent set forth in any Ancillary Agreement, absent fraud or willful misconduct by an Indemnifying Party, the indemnification provisions of this Article VI shall be the sole and exclusive remedy of an Indemnitee for any monetary or compensatory damages or losses resulting from any breach of this Agreement or any Ancillary Agreement and each Indemnitee expressly waives and relinquishes any and all rights, claims or remedies such Person may have with respect to the foregoing other than under this Article VI against any Indemnifying Party. For the avoidance of doubt, all disputes in respect of this Article VI shall be resolved in accordance with Article VIII .

(g) Notwithstanding the foregoing, to the extent any Ancillary Agreement provides procedures for indemnification that differ from the provisions set forth in this Section 6.4 , the terms of the Ancillary Agreement will govern.

(h) The provisions of this Article VI shall apply to Third Party Claims that are already pending or asserted as well as Third Party Claims brought or asserted after the date of this Agreement. There shall be no requirement under this Section 6.4 to give a notice with respect to any Third Party Claim that exists as of the Separation Time. The Parties acknowledge that Liabilities for Actions (regardless of the parties to the Actions) may be partly Air Products Retained Liabilities and partly Versum Liabilities. If the Parties cannot agree on the allocation of any such Liabilities for Actions, they shall resolve the matter pursuant to the procedures set forth in Article VIII . Neither Party shall, nor shall either Party permit its Subsidiaries to, file Third Party Claims or cross-claims against the other Party or its Subsidiaries in an Action in which a Third Party Claim is being resolved.

Section 6.5 Cooperation in Defense and Settlement .

(a) With respect to any Third Party Claim that implicates both Parties in any material respect due to the allocation of Liabilities, responsibilities for management of defense and related indemnities pursuant to this Agreement or any of the Ancillary Agreements, the Parties agree to use commercially reasonable efforts to cooperate fully and maintain a joint defense (in a manner that, to the extent reasonably practicable, will preserve for all Parties any Privilege with respect thereto). The Party that is not responsible for managing the defense of any such Third Party Claim shall, upon reasonable request, be consulted with respect to significant matters relating thereto and may, if necessary or helpful, retain counsel to assist in the defense of such claims. Notwithstanding the foregoing, nothing in this Section 6.5(a) shall derogate from any Party’s rights to control the defense of any Action in accordance with Section 6.4 .

(b) Notwithstanding anything to the contrary in this Agreement, with respect to any Action (i) by a Governmental Entity against Versum relating to matters involving anti-bribery, anti-corruption, anti-money laundering, export control and similar laws, where the facts and circumstances giving rise to the Action occurred prior to the Separation Time or (ii) where the resolution of such Action by order, judgment, settlement or otherwise, could include any condition, limitation or other stipulation that could, in the reasonable judgment of Air Products, adversely impact the conduct of the Air Products Retained Businesses or result in an

45

adverse change to Air Products at shared locations where Versum and Air Products have operating agreements, governmental permits or joint obligations to a Governmental Entity with interdependencies or at non-shared locations, the resolution of such Action may have a precedential adverse effect on then-current Air Products operating agreements, governmental permits or independent obligations to a Governmental Entity, Air Products shall have, at Air Products’ expense, the reasonable opportunity to consult, advise and comment in all preparation, planning and strategy regarding any such Action, including with regard to any drafts of notices and other conferences and communications to be provided or submitted by Versum to any third party involved in such Action (including any Governmental Entity), to the extent that Air Products’ participation does not affect any privilege in a material and adverse manner; provided that to the extent that any such action requires the submission by Versum of any content relating to any current or former officer or director of Air Products, such content will only be submitted in a form approved by Air Products in its reasonable discretion. With regard to the matters specified in the preceding clauses (i) and (ii), Air Products shall have a right to consent to any compromise or settlement related thereto.

(c) Each of Air Products and Versum agrees that at all times from and after the Separation Time, if an Action is commenced by a third party naming two (2) or more Parties (or any member of such Parties’ respective Groups) as defendants and with respect to which one or more named Parties (or any member of such Party’s respective Group) is a nominal defendant and/or such Action is otherwise not a Liability allocated to such named Party under this Agreement or any Ancillary Agreement, then the other Party or Parties shall use commercially reasonable efforts to cause such nominal defendant to be removed from such Action, as soon as reasonably practicable.

Section 6.6 Indemnification Payments . Indemnification required by this Article VI shall be made by periodic payments of the amount of Indemnifiable Losses in a timely fashion during the course of the investigation or defense, as and when bills are received or an Indemnifiable Loss incurred.

Section 6.7 Indemnification Obligations Net of Insurance Proceeds and Other Amounts .

(a) Any recovery by any Indemnitee for any Indemnifiable Loss subject to indemnification pursuant to this Article VI shall be calculated (i) net of Insurance Proceeds actually received by such Indemnitee with respect to any Indemnifiable Loss (such proceeds shall be reduced by the present value, based on that Party’s then-cost, of short-term borrowing of future premium increases known at such time) and (ii) net of any proceeds actually received by the Indemnitee from any third party with respect to any such Liability corresponding to the Indemnifiable Loss (“ Third Party Proceeds ”). Accordingly, the amount which any Indemnifying Party is required to pay pursuant to this Article VI to any Indemnitee pursuant to this Article VI shall be reduced by any Insurance Proceeds or Third Party Proceeds theretofore actually recovered by or on behalf of the Indemnitee in respect of the related Indemnifiable Loss. If an Indemnitee receives a payment required by this Agreement from an Indemnifying Party in respect of any Indemnifiable Loss (an “ Indemnity Payment ”) and subsequently receives Insurance Proceeds or Third Party Proceeds, then the Indemnitee shall pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Insurance Proceeds or Third Party Proceeds had been received, realized or recovered before the Indemnity Payment was made.

46

(b) Any Indemnity Payment shall be increased as necessary so that after making all payments corresponding to Taxes imposed on or attributable to such Indemnity Payment, the Indemnitee receives an amount equal to the sum it would have received had no such Taxes been imposed.

(c) The Parties hereby agree that an insurer or other third party that would otherwise be obligated to pay any amount shall not be relieved of the responsibility with respect thereto or have any subrogation rights with respect thereto by virtue of any provision contained in this Agreement or any Ancillary Agreement, and that no insurer or any other Third Party shall be entitled to a “windfall” ( e.g. , a benefit they would not otherwise be entitled to receive, or the reduction or elimination of an insurance coverage obligation that they would otherwise have, in the absence of the indemnification or release provisions) by virtue of any provision contained in this Agreement or any Ancillary Agreement. Each Party shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to collect or recover, or allow the Indemnifying Party to collect or recover, or cooperate with each other in collecting or recovering, any Insurance Proceeds that may be collectible or recoverable respecting the Liabilities for which indemnification may be available under this Article VI . Notwithstanding the foregoing, an Indemnifying Party may not delay making any indemnification payment required under the terms of this Agreement, or otherwise satisfying any indemnification obligation, pending the outcome of any Actions to collect or recover Insurance Proceeds, and an Indemnitee need not attempt to collect any Insurance Proceeds prior to making a claim for indemnification or receiving any Indemnity Payment otherwise owed to it under this Agreement or any Ancillary Agreement.

Section 6.8 Contribution . If the indemnification provided for in this Article VI is unavailable for any reason to an Indemnitee (other than failure to provide notice with respect to any Third Party Claims in accordance with Section 6.4(b) ) in respect of any Indemnifiable Loss, then the Indemnifying Party shall, in accordance with this Section 6.8 , contribute to the Indemnifiable Losses incurred, paid or payable by such Indemnitee as a result of such Indemnifiable Loss in such proportion as is appropriate to reflect the relative fault of Versum and each other member of the Versum Group, on the one hand, and Air Products and each other member of the Air Products Group, on the other hand, in connection with the circumstances which resulted in such Indemnifiable Loss. With respect to any Indemnifiable Losses arising out of or related to information contained in the Distribution Disclosure Documents or other securities law filing, the relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact relates to information supplied by the Versum Business of a member of the Versum Group, on the one hand, or the Air Products Retained Business or a member of the Air Products Group, on the other hand.

Section 6.9 Covenant not to Sue . Each Party hereby covenants and agrees that none of it or the members of such party’s Group or any Person claiming through it shall bring suit or otherwise assert any claim against any Indemnitee, or assert a defense against any claim asserted by any Indemnitee, before any court, arbitrator, mediator or administrative agency

47

anywhere in the world, alleging that: (a) the assumption of any Versum Liabilities by Versum or a member of the Versum Group on the terms and conditions set forth in this Agreement and the Ancillary Agreements is void or unenforceable for any reason; (b) the retention of any Air Product Retained Liabilities by Air Products or any member of the Air Products Group on the terms and conditions set forth in this Agreement and the Ancillary Agreements is void or unenforceable for any reason or (c) the provisions of this Article VI are void or unenforceable for any reason.

Section 6.10 Limitation of Liability . IN NO EVENT SHALL ANY PARTY OR ANY OTHER MEMBER OF ANY GROUP BE LIABLE TO ANY OTHER PARTY OR ANY MEMBER OF ANOTHER GROUP FOR PUNITIVE, CONSEQUENTIAL, SPECIAL OR INDIRECT DAMAGES, INCLUDING LOSS OF FUTURE PROFITS, REVENUE OR INCOME, DIMINUTION IN VALUE OR LOSS OF BUSINESS REPUTATION OR OPPORTUNITY, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY (INCLUDING NEGLIGENCE) ARISING IN ANY WAY OUT OF THIS AGREEMENT, REGARDLESS OF WHETHER SUCH DAMAGES WERE FORESEEABLE OR SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES EXCEPT TO THE EXTENT AWARDED BY A COURT OF COMPETENT JURISDICTION IN CONNECTION WITH A THIRD-PARTY CLAIM.

Section 6.11 Additional Matters; Survival of Indemnities .

(a) The indemnity agreements contained in this Article VI shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Indemnitee; and (ii) the knowledge by the Indemnitee of Indemnifiable Losses for which it might be entitled to indemnification hereunder. The indemnity agreements contained in this Article VI shall survive the Distribution.

(b) The rights and obligations of any member of the Air Products Group or any member of the Versum Group, in each case, under this Article VI shall survive (i) the sale or other Transfer by any Party or its respective Subsidiaries of any Assets or businesses or the assignment by it of any Liabilities, with respect to any Indemnifiable Loss of any Indemnitee related to such Assets, businesses or Liabilities and (ii) any merger, consolidation, business combination, restructuring, recapitalization, reorganization or similar transaction involving either Party or any of its Subsidiaries.

Section 6.12 Environmental Matters .

(a) Exchange of Information . Without limiting any other provision of this Agreement, each of Air Products and Versum agrees to provide, or cause to be provided, at any time before, on, or after the Separation Time, as soon as reasonably practicable after written request therefore, reasonable access to any non-privileged Information in the possession or under the control of any member of such respective Group and reasonable access to its employees to the extent that (i) such Information relates to, or such employees have relevant knowledge regarding, specific alleged Environmental Liabilities, including the requesting Party’s alleged or potential link to environmental contamination at an Off-Site Location or real property that was allegedly owned or operated by any member of the Air Products Group and any operating group,

(b) Substitution .

(i) Versum Group shall use its reasonable best efforts to obtain any consents, transfers, assignments, Assumptions, waivers, or other legal instruments necessary to cause the appropriate member of the Versum Group to be fully substituted for Air Products or any other member of the Air Products Group with respect to: (i) any order, decree, judgment, agreement or Action with respect to Versum Assumed Environmental Liabilities that are in effect as of the Separation Time; or (ii) Environmental Permits, financial assurance obligations or instruments, or other environmental approvals or filings associated with the Versum Assets. Versum shall inform the applicable Governmental Entity about its assumption of the Environmental Liabilities associated with the matters covered by this Section 6.12(b) and request that such Governmental Entities direct all communications, requirements, notifications and/or official letters related to such matters to Versum. Air Products shall use its reasonable best efforts to provide necessary assistance or signatures to Versum to achieve the purposes of this section.

(ii) Until such time as Versum and Air Products complete the substitutions outlined in Section 6.12(b)(i) above, Versum shall comply with all applicable Environmental Laws, including all reporting obligations, and the terms and conditions of all orders, decrees, judgments, agreements, Actions, Environmental Permits, financial assurances, obligations, instruments or other environmental approvals or filings that remain in Air Products’ name relating to the Versum Assets and the Versum Assumed Environmental Liabilities.

Unless otherwise required by a Final Determination, this Agreement or the Tax Matters Agreement or otherwise agreed to among the Parties, for U.S. federal Tax purposes, any payment made pursuant to this Agreement (other than any payment of interest pursuant to Section 10.11 ) by: (i) Versum to Air Products shall be treated for all Tax purposes as a distribution by Versum to Air Products with respect to stock of Versum occurring immediately before the Distribution; or (ii) Air Products to Versum shall be treated for all Tax purposes as a tax-free contribution by Air Products to Versum with respect to its stock occurring immediately before the Distribution; and in each case, no Party shall take any position inconsistent with such treatment. In the event that a Taxing Authority asserts that a Party’s treatment of a payment pursuant to this Agreement should be other than as set forth in the preceding sentence, such Party shall use its commercially reasonable efforts to contest such challenge.

Section 10.22 No Waiver . No failure to exercise and no delay in exercising, on the part of any Party, any right, remedy, power or privilege hereunder or under the Ancillary Agreements shall operate as a waiver hereof or thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

Section 10.23 No Admission of Liability . The allocation of Assets and Liabilities herein (including on the schedules hereto) is solely for the purpose of allocating such Assets and Liabilities between Air Products and Versum and is not intended as an admission of liability or responsibility for any alleged Liabilities vis-à-vis any third party, including with respect to the Liabilities of any non-wholly owned subsidiary of Air Products or Versum.
