9.2	Responsibility for Satisfaction of the Closing Conditions

(a)

Closing Conditions regarding Merger Clearances

(i)

The Purchasers shall within ten (10) Business Days after the date of this Agreement duly submit the legally required anti-trust filings for the transactions contemplated in this Agreement on behalf of the Purchasers and the Sellers to the Anti-Trust Authorities (the "Anti-Trust Filings").

(ii)

The Purchasers shall (x) be responsible for the Anti-Trust Filings as well as for all requests, investigations or enquiries from the Anti-Trust Authorities, provided, however, that the Sellers shall cooperate with the Purchasers to the extent necessary to assist the Purchasers in preparation of the Anti-Trust Filings and shall without undue delay (unverzüglich) provide to the Purchasers information required for the purposes of the Anti-Trust Filings or otherwise reasonably requested by any Anti-Trust Authority, provided, however, that the contents of any written communication between the Purchasers and any Anti-Trust Authority require the prior approval of the Sellers, and (y) promptly and closely coordinate in all respects with the Sellers in the preparation of the Anti-Trust Filings and in any discussions or negotiations with an Anti-Trust Authority.

(iii)

The Parties shall without undue delay (unverzüglich) submit all necessary information reasonably required by an Anti-Trust Authority and take all other actions required in order to obtain all approvals or to cause any applicable waiting period to commence and expire.

(iv)

The Purchasers and the Sellers shall (A) consult on a regular basis on the progress of the proceedings before the Anti-Trust Authorities, (B) promptly provide each other with copies of any written communication received or sent in connection with any such proceedings, (C) give each other and their respective advisors the opportunity to participate in all meetings and conferences with the Anti-Trust Authorities, and (D) ensure that any exchange of information in the context of the Anti-Trust Filings is on a reasonable and customary basis in any event complies with all applicable anti-trust laws.

(v)

The Purchasers shall submit evidence to the Sellers of the satisfaction of the Closing Condition set forth in Section 9.1(a)(i) (Merger Clearance), or the impossibility to satisfy such Closing Condition without undue delay after becoming aware of such satisfaction or such impossibility to satisfy.

In order to enable the Parties to close the transactions as contemplated under this Agreement in a timely manner, the Purchasers shall undertake and shall cause (dafür einstehen) their Affiliates to use reasonable endeavors to ensure satisfaction of the Merger Clearances, but shall not be required to dispose or hold separate any assets other than in respect of Section 9.2(b) below. The Purchasers undertake not to, and shall cause (dafür einstehen) their Affiliates not to, enter into any transaction, or any agreement to effect any transaction (including any merger or acquisition) that might reasonably be expected to make it materially more difficult, or to materially increase the time required, to obtain the Merger Clearances or which would create the requirement to obtain additional clearances from merger control authorities.

(b)

Merger Clearance Delays

To the extent that there are delays (due to no fault of any of the Parties) in obtaining or it becomes evident (in the reasonable opinion of the Parties) that there may be a failure to obtain any Merger Clearance on or before the Long Stop Date, the Parties will discuss in good faith what, if any, measures or steps may or can be taken both to expedite Closing and/or in obtaining these Merger Clearances and any confirmations that these will be obtained provided always that these measures or steps are compatible with applicable law and/or regulations.

Without prejudice to the foregoing, to the extent that (i) Closing of the Transaction is reasonably likely not to occur as a result of any Merger Clearance not being satisfied on or prior to the Long Stop Date (other than in respect of Germany, Austria, Spain and Brazil) the Parties will take such reasonable measures or steps so as to prevent the failure to obtain any Merger Clearance preventing Closing from occurring on or before the Long Stop Date or (ii) there is no other Regulatory Closing Condition outstanding save in respect of Russia and there are delays (due to no fault of any of the Parties) in respect of this Russian Merger Clearance, then the Parties also agree to take all measures or steps reasonably required to give effect to a "hold separate" in respect of ASK Chemicals CIS Limited to facilitate Closing as soon as reasonably practicable, such hold separate to be on customary and reasonable terms for a transaction of this type and nature.

The Purchaser shall use best commercial efforts to ensure that any consents required from its Lenders are obtained to give effect to such "holder separate" arrangement or such other measures or steps being taken.

9.3	Termination Rights

(a)

If at any time prior to the Closing Date a Seller or a Purchaser becomes aware of any event, circumstance, condition or breach that would be reasonably likely to prevent a Closing Condition being satisfied, it shall inform the other Parties in accordance with Section 9.1(b) providing such detail in relation thereto (to the extent available to the relevant Party at the time) to enable the other Parties to make an accurate assessment of the situation (and, for the avoidance of doubt, nothing in this Section 9.3(a) shall limit or otherwise affect the rights or remedies available to any Party).

(b)

If at any time a Seller or a Purchaser becomes aware (tatsächliche Kenntnis) of a Material Representation Breach or Material Interim Covenant Breach (a "Reps or Covenant Breach"), then such party shall notify the other Sellers and Clariant Corp. and the Purchasers without undue delay, providing reasonable details in relation to such Reps or Covenant Breach (a "Reps or Covenant Breach Notice").

(c)

Upon the delivery or receipt of a Reps or Covenant Breach Notice by or to the Sellers (as applicable), the Sellers may, in their sole discretion, decide to, within a period of thirty (30) Business Days (the "Cure Period"), use reasonable endeavors to procure that the Reps or Covenant Breach is prevented or remedied in a manner that causes it to cease to be a Reps or Covenant Breach (for the avoidance of doubt, including if the relevant Losses or detrimental effects are lowered below the relevant thresholds or qualifiers).

(d)

If the Sellers and the Purchasers (in each case, acting reasonably) agree in writing at any time during the Cure Period that the Reps or Covenant Breach is not capable of being prevented or cured so that the relevant Closing Condition cannot be satisfied by the Long Stop Date, the Purchasers shall be entitled to, within a period of ten (10) Business Days (but in any case only prior to the Closing Date) from the date of such agreement terminate this Agreement by joint written notice to the Sellers and Clariant Corp. without liability on the part of the Purchasers in respect of such termination.

(e)

If after the Cure Period, the relevant Reps or Covenant Breach continues to exist, then the Purchasers shall be entitled to terminate this Agreement by joint written notice to the Sellers within a period of ten (10) Business Days from the date following the end of the Cure Period (but in any case only prior to the Closing Date), without liability on the part of the Purchasers in respect of such termination.

Following the receipt or issuance by any Purchaser of a Reps or Covenant Breach Notice prior to Closing, if the Purchasers do not exercise their right to terminate this Agreement in accordance with Sections 9.3(d) or 9.3(e), the Purchasers shall not then, following Closing, be permitted to exercise any rights they may have to bring Proceedings against the Sellers in respect of any Material Business Representation Breach disclosed in the Reps and Covenant Breach Notice, unless (i) the Purchasers have first given prior to the Closing Date not less than ten (10) Business Days' (the "Sellers' Termination Period") notice to the Sellers of their intention not to terminate this Agreement pursuant to Sections 9.3(d) or 9.3(e) and preserve their right to bring Proceedings against the Sellers in respect of the Material Business Representation Breach disclosed in the Reps and Covenant Breach Notice (a "Sellers' Termination Right Notice") and (ii) the Sellers have not exercised their right to terminate this Agreement on or prior to the expiry of the Sellers' Termination Period in accordance with Section 9.3(g). The Purchasers shall notify the Sellers without undue delay whether they will exercise their rights to terminate this Agreement or preserve their rights in accordance with Sections 9.3(d), 9.3(e) or 9.3(f).

(g)

Upon receipt of a Sellers' Termination Right Notice, each of the Sellers may prior to the expiry of the Sellers' Termination Period terminate this Agreement without liability on part of the Sellers in respect of such termination.

(h)

If the Purchasers or the Sellers do not exercise their right to terminate this Agreement in accordance with Sections 9.3(d) or 9.3(e) or Section 9.3(g) prior to the Closing Date, the Sellers and the Purchasers shall not thereafter be permitted to terminate this Agreement on the basis of such Reps or Covenant Breach and the Closing Conditions in Sections 9.1(a)(ii) and 9.1(a)(iii) shall be deemed to have been validly waived; provided that, for the avoidance of doubt, if following the lapse of the respective termination periods under Sections 9.3(d) or 9.3(e), respectively, but prior to the Closing Date, any material facts or circumstances related to such Reps or Covenant Breach either (i) first become known to the Purchasers or (ii) any known material facts or circumstances related to such Reps or Covenant Breach change in a material manner, in each case of (i) or (ii) where the newly known or changed facts and circumstances materially increase Losses resulting from or, respectively, the negative impact of such Reps or Covenant on the benefits otherwise to be received by the Purchasers in the Transaction, then the Purchasers shall notify the Sellers of such newly known or changed facts in writing forthwith, following which notice this shall be treated as a new Reps and Covenants Breach to which the processes set out in Sections 9.3(a) to 9.3(h) shall apply.

(i)

The Parties agree that, to the extent necessary, the Closing Date shall be postponed to such date (which shall then be the new Closing Date) as is required at a minimum to accommodate the processes set out in Sections 9.3(a) to 9.3(g), provided always that the Closing Date shall in no event be postponed further than the Long Stop Date.

(j)

Notwithstanding any other provision of this Agreement, in the event that the Closing Conditions are not fulfilled or waived in accordance with this Agreement, at the latest on the Long Stop Date, the Purchasers and each of the Sellers shall be entitled to terminate this Agreement by written notice to the Sellers and Clariant Corp., or the Purchasers, respectively, without liability on their respective part in respect of such termination, save for accrued liabilities as set out in Section 9.4.

(k)

The Parties shall use their reasonable efforts to ensure that where the condition set out in Section 9.1(a)(iv) has not been satisfied on either (i) the date of last satisfaction of the Regulatory Closing Conditions and/or (ii) the Closing Date, such condition is satisfied as soon as reasonably practical.

In the event that either the Purchasers or the Sellers terminate this Agreement in accordance with Sections 9.3(d), 9.3(e), 9.3(g) or 9.3(j), all obligations of the Parties shall end and this Agreement shall terminate, save that (i) any liability of any Party for damages which are already due on the date of termination or for damages for a breach of any other obligation under this Agreement shall survive and remain in existence, (ii) the provisions of Section 20.15(a)) shall apply in respect of the limitation of liability of any Party pursuant to Section 9.3 and this Section 9.4 and (iii) the provisions in Section 20 of this Agreement shall survive and remain in full force and effect.

General

The Parties have discussed and negotiated if and to what extent the Sellers and Clariant Corp. shall be liable for potential defects relating to the Sold Shares, the Tecpro Holding Credit Facility and the Business and have decided to depart from the statutory warranty provisions (gesetzliche Gewährleistungsregeln).

The Sellers, Clariant Corp. and the Purchasers agree and explicitly confirm that no Sellers' Representation shall be construed as a seller's guarantee (Garantie für die Beschaffenheit der Sache) within the meaning of Sections 443 and 444 of the German Civil Code (BGB).

14.4	Procedures

(a)

Claims Notice; Access to Information. If the Purchasers or any Group Entity becomes aware after the date of this Agreement of any facts or circumstances which reasonably indicate that there has been a breach of this Agreement or which may reasonably give rise to any Proceedings under this Agreement against the Sellers, the Purchasers shall give the Sellers and Clariant Corp. written notice thereof no later than twenty (20) Business Days following the discovery of such facts and circumstances (the "Claims Notice"). The Claims Notice shall state in reasonable detail the nature of the alleged breach and claim, respectively, and, to the extent feasible, the amount of Losses resulting therefrom (or, in case of an indemnity claim) covered thereby. To the extent reasonably required by the Sellers and Clariant Corp. to assess the alleged breach and claim, respectively, and the resulting (or covered) Losses, the Purchasers shall provide, and shall cause the Group Entities, having received reasonable notice, to provide to such Sellers, Clariant Corp. and their professional advisors (i) access during normal business hours to their relevant books, records and assets, premises, employees and management (as a reasonably required), as well as (ii) copies of relevant documents and other information in each case as are reasonably and required. The Parties hereby agree that any claim notice that the Purchasers notify by way of a Claims Notice to the Sellers and Clariant Corp. shall (if it has not previously been satisfied, settled or withdrawn) cease to exist (erlöschen) if the Purchasers do not initiate, within six (6) months following the receipt of the Claims Notice by the Sellers and Clariant Corp., court proceedings against the Seller concerned (or Clariant Corp. as the case may be) in accordance with Section 20.14, any earlier time limitation (Verjährung) shall remain unaffected. Subject to Section 14.3(a)(vi) and excluding the preceding sentence, failure by the Purchasers to follow the claim procedures set out in this Section 14.4(a) shall not in and of itself prejudice the rights of a Purchaser to make a claim and is without prejudice to the Sellers and Clariant Corp. rights pursuant to Section 14.1.

(b)

Third-Party Claims. If the facts and circumstances which reasonably indicate that a (a) breach of this Agreement has occurred or (b) which may give rise to any Proceeding under this Agreement raise the concern (i) that a third party (including, without limitation, any Authority (whether competent or not) may have or raise a claim against a Group Entity or the Purchasers, or (ii) that an audit or examination is being or will be conducted by any Authority (whether competent or not) (each ((i) and (ii)) a "Third-Party Claim"), the Purchasers shall, without prejudice to its obligations under Section 14.2(a), provide, and shall cause the Group Entities to provide to the Sellers and Clariant Corp., together with the Claims Notice or as soon as possible thereafter, copies of all documents reasonably required that set forth the Third-Party Claim and its underlying facts and circumstances. The Purchasers shall defend or settle each Third-Party Claim in consultation with the Sellers and Clariant Corp. and taking the Sellers' and Clariant Corp.'s reasonable requests into account and shall keep the Sellers and Clariant Corp. informed of such proceedings (to the fullest extent that is reasonable). If legally permitted and requested by the Sellers and/or Clariant Corp. in respect of claims relating to a Business Representation and/or a Fundamental Representation or Other Breach or indemnity claims pursuant to Section 17.4 (Tecpro Holding) (an "Assumed Claim"), the Purchasers shall give the Sellers and Clariant Corp. the opportunity to defend or settle such Assumed Claim, at their sole discretion. To the extent the Sellers and/or Clariant Corp. choose not to defend the claim directly by proxy, the Purchasers shall defend or settle the Assumed Claim upon the request and in accordance with the reasonable instructions by the Sellers and/or Clariant Corp. The Sellers and Clariant Corp. shall be entitled to participate in and direct all negotiations and correspondence with the third party and to appoint and instruct counsel in respect of the Assumed Claim. No action by the Sellers and Clariant Corp. or any of their respective Representatives in connection with the defense shall be construed as an express or implied acknowledgement (Anerkenntnis) that a breach has occurred (or that an indemnity claim has been triggered under this Agreement) or of the underlying facts and circumstances of the alleged breach (or indemnity). All costs and expenses incurred by the Sellers or Clariant Corp., as well as, in the case of an instruction of the Purchasers, the reasonable costs and out-of-pocket expenses of the Group Entities and the Purchasers in defending the Third-Party Claim shall be borne by the Sellers or by Clariant Corp. (as the case may be). If and to the extent the applicable court or arbitral panel determines that no breach has occurred (or no indemnity exists), any costs and expenses reasonably incurred by the Sellers or Clariant Corp. in connection with the defense (including reasonable external advisors' fees) shall be borne by the Purchasers. The Purchasers shall be kept informed (to the fullest extent reasonable) of, and consulted about, such litigation or proceeding of an Assumed Claim for which the Sellers and/or Clariant Corp. have assumed the defense. Regardless of whether the Sellers or Clariant Corp. elect to defend the Third-Party Claim themselves or not, the Purchasers shall (and shall cause the Group Entities to) cooperate (to the fullest extent that is reasonable) with the Sellers and Clariant Corp. as requested by the Sellers and Clariant Corp. for the purpose of avoiding, disputing, defending, appealing, compromising or contesting the Third-Party Claim and shall (and shall cause the Group Entities to) (1) provide to the Sellers and Clariant Corp. and its professional advisors access during normal business hours to the relevant books, records, assets, premises, employees and their management (as well as copies of relevant documents and other information) as is reasonably requested and required, (2) afford the Sellers and Clariant Corp. reasonable opportunity to comment on and discuss with the Purchasers and the Group Entities any actions which are necessary or appropriate to be taken or omitted for the defense of the Third-Party Claim, (3) afford the Sellers and Clariant Corp. the opportunity to comment on and review any reports and documents to the extent permissible by law and regulation, (4) deliver to the Sellers and Clariant Corp. without undue delay copies of all relevant orders (Bescheide), decisions, filings, motions and other documents of any court, authority or party to the conflict, (5) diligently conduct the defense (to the extent not controlled by the Sellers and Clariant Corp.) in order to mitigate Losses the fullest extent possible, and (6) not acknowledge or settle the Third-Party Claim without the Sellers' and Clariant Corp.'s prior written consent, such consent not to be unreasonably withheld or unreasonably delayed. Any costs and expenses incurred by the Purchasers and the Group Entities in connection with the cooperation or defense, to the extent not instructed by the Sellers, shall be borne by the Purchasers, except for any Losses to be indemnified by the Sellers and Clariant Corp. in accordance with this Agreement. For the avoidance of doubt, nothing in this Section 14.4(b) shall be construed as a right of the Sellers or Clariant Corp. to force the Purchasers or the Group Entities to ▇▇▇ any regulatory Authority.

(c)

Any rights and obligations of the Purchasers under Sections 14.4(a) and 14.4(b) shall only be against such Party which may be liable for the respective breach or indemnity or be otherwise concerned and (ii) any rights and obligations of the Sellers and Clariant Corp. under Sections 14.4(a) and 14.4(b) shall only be with the Party which may be liable for the respective breach or indemnity be otherwise concerned.

15.

LEAKAGE

15.1	Warranty and Undertakings

Each of the Sellers:

(a)

warrants to the Purchasers that from (but excluding) the Locked Box Date to (and including) the date of this Agreement, there has been; and

(b)

undertakes to the Purchasers to procure that from the date of this Agreement to (and including) the Closing Date, there will be,

no Leakage to it or for its benefit or to or for the benefit of a member of such Seller's Group provided that the Sellers shall have no liability to the Purchasers under Sections 15.1 or 15.2 if Closing does not occur.

The Parties agree that the rights pursuant to Section 15.3 are the sole remedy in case of such Leakage.

15.2	Notification of Leakage

Without prejudice to Section 6.1(d), each Seller severally undertakes to the Purchasers to notify the Purchasers in writing as soon as is reasonably practicable upon becoming aware (positive Kenntnis) of any receipt of the benefit of Leakage by any Seller or any member of any Seller's group from (but excluding) the Locked Box Date to (and including) the Closing Date.

15.3	Payment and Adjustment for Leakage

(a)

Subject to Section 15.4 if any Leakage is notified or comes to the attention of the Purchasers on or prior to Closing then, subject further to such Leakage not having been remedied and the relevant Seller (the "Relevant Seller") agreeing in writing that Leakage has occurred and agreeing the amount of such Leakage applicable to such Relevant Seller (an "Agreed Leakage Amount"), the Purchasers shall be entitled to reduce the proportion of the Purchase Price to be paid to the Relevant Seller pursuant to Section 4 by the full amount of such Agreed Leakage Amount (and the payment of the amount of the Purchase Price so reduced shall be an absolute discharge of the Purchasers' obligations hereunder in respect of the Purchase Price to be paid to the Relevant Seller pursuant to this Agreement).

(b)

Subject to Section 15.4 if any Leakage is notified or comes to the attention of the Purchasers after Closing which has been incurred to the period from (but excluding) the Locked Box Date to (and including) the Closing Date (other than any Agreed Leakage Amount which has been taken into account in the determination of the Purchase Price pursuant to Section 4) the relevant Seller who receives or benefits from (or whose group receives or benefits from) such Leakage shall upon actual receipt of such benefit on demand by the Purchasers pay to the Purchasers by way of adjustment to the Sold Shares Purchase Price an amount in cash equal to the amount of such Leakage, unless – and to the extent – the Leakage has otherwise been remedied.

15.4

In the event of Leakage falling under (e) to (g) of the definition of Leakage, each Seller shall pay pursuant to Section 15.3, its Pro-Rata Share of the Leakage. "Pro Rata Share", shall mean in relation to Clariant Produkte a 50% (in words: fifty percent) share and in relation to any Ashland and Ashland International Holding, their respective pro rata share based on the proportion that the Purchase Price receivable by each of them pursuant to this Agreement bears to the aggregate amount of Purchase Price receivable by all Sellers pursuant to this Agreement, provided, however, that Clariant Produkte shall be entitled to or be obliged to pay (as applicable) 100% (in words: one hundred percent) of the amounts insofar as they relate only to Tecpro Holding.

15.5

The Sellers acknowledge that to the extent that either (i) the engagement letters entered into by a Group Entity with the professional advisers in connection with the Transaction (with details of the fees chargeable comprising the Disclosed Transaction Costs) are novated prior to Closing and/or (ii) such fees are not settled by the Sellers, all such fees incurred by the advisers from the Locked Box Date to the Closing Date shall be deemed as Agreed Leakage Amount.

16.	TAX INDEMNITY

16.1	Tax Indemnification

Subject to and in accordance with Section 20.15, the Sellers shall pay at the Purchasers' discretion, either to the relevant Group Entity or to the Purchasers (i) the amount of any Relevant Taxes (a "Tax Indemnification Claim"); and (ii) any Relevant Taxes arising from any Tax Representation Breach (a "Tax Representation Claim") together with any reasonable external advisor costs and expenses properly incurred by the Purchasers or the relevant Group Entity in connection with making a successful Tax Indemnification Claim, but in any case only

(a)

to the extent that the Relevant Taxes or the liability to Taxes giving rise to a Tax Representation Claim have not been paid to the competent Tax Authority prior to the Locked Box Date;

(b)

to the extent that the Relevant Taxes or the liability to Taxes giving rise to a Tax Representation Claim are not the result of any change in law or in the generally published interpretation or practice of any Tax Authority coming into force after the Locked Box Date;

(c)

to the extent that the Relevant Taxes or the liability to Taxes giving rise to a Tax Representation Claim are not the result of (i) any change in the accounting and taxation principles or practices of any of the Group Entities or any successor to all or parts of their business (including the methods of submitting Tax Returns) introduced after the Closing Date except where any such change is required by law or generally accepted accounting principles relevant for Tax purposes, or (ii) any transaction, action or omission (including the change in the exercise of any Tax election right, the approval or implementation of any reorganization measure or the sale of any asset) taken by the Purchasers or the relevant Group Entity or any successor to all or parts of their business after the Closing Date other than any transaction, action or omission as a result of a binding obligation or commitment entered into by a Group Entity prior to the Closing Date;

(d)

to the extent the Relevant Taxes or the liability to Taxes giving rise to a Tax Representation Claim are not caused or increased by any failure of the Purchasers to comply with any of their covenants or obligations set forth in this Section 16; and

(e)

to the extent that the Relevant Taxes or the liability to Taxes giving rise to a Tax Representation Claim are not specifically and expressly taken into account in computing the Final Tax Adjusting Amount.

Where the Relevant Taxes relates to Tecpro Holding, references to Locked Box Date in Section 16.1(a) to (e) shall be read as references to Closing Date.

If and to the extent the Sellers directly or indirectly hold less than 100% (in words: one hundred percent) of the relevant Group Entity, the Tax Claim shall be limited to the total amount to be indemnified multiplied by Sellers' direct or indirect shareholding percentage.

Any payment on the Tax Claim shall be due and payable within ten (10) Business Days after the Sellers have been notified in writing by the Purchasers about the payment obligation and the corresponding payment date and the circumstances giving rise to the payment obligation pursuant and in accordance with this Agreement and have received, where available, a copy of the relevant Tax assessment notice of the competent Tax Authority, but in no case earlier than two (2) Business Days before the Tax to be indemnified has to be paid to the Tax Authority so as to avoid any liability to interest and/or penalties. On a reasonable request of a Seller the Purchasers shall provide to such Seller (with copy to the other Sellers) any relevant document or data which may enable such Seller to review the validity of the indemnification request. On reasonable request of a Seller the Purchasers shall, where permitted by law, procure that the relevant Group Entity applies for a deferred payment date. If a Tax case is still open but Taxes are due and payable any indemnification payment shall be considered as an advanced payment to the Purchasers. If subsequently the Tax for which the advanced payment has been made is reduced again by way of Tax assessment or otherwise lowered the difference between the higher advance payment and the lower Tax liability shall be without undue delay reimbursed by the Purchasers to the Sellers (and, for the avoidance of doubt, Section 16.2 shall not apply to such amounts).

16.2	Corresponding Savings, Over-Provisions and Refunds

(a)

If, after the Closing Date, the Purchasers or any Group Entity become(s) aware that:

(i)

any Relevant Taxes or the liability to Taxes which gives rise to a Tax Representation Claim which has resulted in a payment being made by (or becoming due from) the Sellers under this Section 16 has given rise to a corresponding Tax saving for a Group Entity (a "corresponding saving"); or

(ii)

(ii)

Amendment to Master Contribution and Sale Agreement. The Sellers shall be entitled to amend on or prior to the Closing Date the Master Contribution and Sale Agreement, such that Section 7.3(b), and the Cap provided therein, applies to all claims brought pursuant to Section 8.1 (to the extent relating to Environmental Losses (as defined in the Master Contribution and Sale Agreement)) and Section 8.2 thereof (but for the avoidance of doubt the Cap shall not apply to claims brought pursuant to Section 8.4 of the Master Contribution and Sale Agreement). The Sellers shall (i) give the Purchaser reasonable notice of the amendments they propose to make give effect to the terms of this Section 20.15(b)(ii) and shall take into account, in their reasonable opinion, any reasonable comments received from the Purchasers required to give effect to the terms of this Section 20.15(b)(ii) and (ii) provide copies of the duly executed amendments within 5 Business Days to the Purchasers after effectiveness of the amendment.

(iii)

Priority of Claims. The Purchasers shall not be entitled to bring any claims under this Agreement (including, but not limited to, any claims under Section 17.1 if a corresponding claim (relating to the same subject matter) can be made against a Seller or a Sellers' Affiliate under the Master Contribution and Sale Agreement. This exclusion also applies if the claim cannot be collected against a Seller or a Sellers' Affiliate if the relevant indemnifying party under the Master Contribution and Sale Agreement becomes insolvent. Further, if a claim can be made under the Master Contribution and Sale Agreement but cannot be recovered in whole or in part because either (i) the cap under the Master Contribution and Sale Agreement for such Seller(s) or its/their Affiliates is exceeded or (ii) as a result of a default or refusal to make payment, a corresponding claim (relating to the same subject matter) can only be brought forward under this Agreement for the outstanding amount of such corresponding claim that remains unsatisfied against such Seller(s) or its Affiliates under the Master Contribution and Sale Agreement.

(iv)

Cap Treatment. If a Purchaser has collected a claim against a Seller or a Sellers' Affiliate under the Master Contribution and Sale Agreement, the amount collected shall not be counted towards (angerechnet) the caps which apply under this Agreement (under Section 14.5 or otherwise) provided that the Purchasers shall not be entitled to recover damages or obtain payment to the extent that they have already recovered or discharged liability more than once in respect of a claim relating to the same subject matter under both the Master Contribution and Sale Agreement and this Agreement.

(v)

Statute of Limitation. If a claim has been brought against a Seller under the Master Contribution and Sale Agreement, the respective limitation period for a corresponding claim (relating to the same subject matter) under this Agreement shall be suspended (gehemmt) until such claim under the Master Contribution and Sale Agreement is finally settled or determined, at which point the balance of the respective limitation period outstanding under this Agreement at the time such claim was brought pursuant to the Master Contribution and Sale Agreement shall continue.

20.16

Claims for Intentional Fraud and Intentional Concealment

(a)

Any provision in this Agreement relating to a limitation of liability of the Sellers or Clariant Corp. shall not apply if and to the extent any claims rights or remedies are based on willful deceit (arglistige Täuschung) or willful misconduct (Vorsatz) of the respective Seller or Clariant Corp. itself.

(b)

If and to the extent the facts or circumstances giving rise to a Representation Breach derive from or are otherwise caused by a Representative of any of the Sellers or the Group Entities committing intentional fraud (Betrug) or intentional concealment (absichtliche Täuschung unter Ausschluss von bedingtem Vorsatz) prior to the Closing then Purchasers' respective claims against the relevant Seller(s) under the Agreement shall not be limited by the General Aggregate Cap but by the maximum amount of liability of the relevant Seller set forth in Section 14.5(c)(iii), unless stricter standards apply in the individual case.

(c)

If a Seller or Clariant Corp. is liable because of willful misconduct (Vorsatz), the liability of the other Sellers and Clariant Corp. or the other Sellers, as the case may be, shall continue to be subject to the limitations and qualifications in this Agreement in particular all caps and other limitations set forth in Section 14.

20.17

Service of Process

The Purchasers hereby appoint German Purchaser as their agent for service of process (Zustellungsbevollmächtigter) for all legal proceedings involving the Purchasers and arising out of or in connection with this Agreement. This appointment shall only terminate upon the appointment of another agent for service for process domiciled in Germany, provided that the agent for service of process is an attorney admitted to the German bar (in Deutschland zugelassener Rechtsanwalt) and his appointment has been notified to and approved in writing by the Sellers and Clariant Corp. (which approval shall not be unreasonably withheld). The Purchasers shall promptly after the date of this Agreement and upon the appointment of any new agent for service of process (as the case may be) issue to the agent a written power of attorney (Vollmachtsurkunde) and shall irrevocably instruct the agent to submit such deed in connection with any service of process under this Agreement.

20.18

Severability

Should any provision of this Agreement be or become, or be deemed to be or become, invalid or unenforceable as a whole or in part, the validity and enforceability of the remaining provisions shall not be affected thereby. Any such invalid or unenforceable provision shall, to the extent permitted by law, be deemed replaced by such valid and enforceable provision as comes closest to the economic intent and purpose of such invalid or unenforceable provision. The same shall apply in the event that this Agreement contains any gaps (Vertragslücken). The Parties are aware of the decision of the Federal Supreme Court (Bundesgerichtshof) of September 24, 2002. However, it is the express intent of the Parties that this Section 20.18 shall not be construed as a mere reversal of the burden of proof (Beweislastumkehr) but rather as a contractual exclusion of Section 139 of the German Civil Code (BGB) in its entirety.

Upon request of the persons appearing, the Notary effected the following notarization in the offices of ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, ▇▇▇▇▇▇▇▇▇ ▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇ ▇▇▇▇.

Prior to the following notarization, the Notary asked the persons appearing whether he or any other person with whom he is associated for the purpose of joint professional practice, has already acted or is currently acting, except in his function as a notary, in the subject matter of this notarization. The persons appearing declared that this is not the case.

The persons appearing requested the Notary to notarize the following notarial deed partly in English and partly in German language. The Notary is in command of the English and German language and has ascertained to his satisfaction that also the persons appearing are in command of the English and German language. The Notary advised the persons appearing that they are entitled to have an interpreter present for the purposes of this notarial recording. The persons appearing waived such right.

The effectiveness of the presented powers of attorney and the signing authority of the persons appearing cannot ultimately be determined by the Notary. In particular, the Notary advised the persons appearing that only the original of a power of attorney may give evidence about the signing authority of the persons appearing and that it is not possible to verify the signing authority on the basis of a simple copy. Moreover, the Notary advised the persons appearing that he cannot ultimately verify whether the non-German entities represented by the persons appearing exist, how those non-German entities are validly represented, whether the appropriate persons signed the presented powers of attorney and whether the persons appearing effectively are released from the restrictions set forth in § 181 German Civil Code (BGB) and thus are able to represent more than one party simultaneously. Neither the Notary nor the persons appearing accept any liability for the existence, validity and/or the appropriate scope of the presented powers of attorney. The Notary instructed the persons appearing that this deed would be pending ineffective (schwebend unwirksam) if one or several powers of attorney are non-existent, ineffective, too short in scope or if the persons appearing are not effectively released from the restrictions set forth in § 181 German Civil Code (BGB). The persons appearing nevertheless requested the following to be notarized (beurkundet) on the basis of the presented powers of attorney.

The exhibits listed below are contained in the reference deed recorded by the Notary on April 2, 3, 4, 6 and 7, 2014 (Deed No. 126 / 2014 (the “Reference Deed”). The original of the Reference Deed was present for the inspection of the persons appearing during the entire recording of this deed. Reference is made herewith to this Reference Deed according to § 13a German Act on Notarial Recordings (BeurkG) and its content is made subject to the agreements recorded in this deed. The persons appearing declared that the content of the Reference Deed is fully known to them. The Notary advised the persons appearing about the consequences of such referencing. The persons appearing rejected the offer of the Notary to read the Reference Deed aloud and to attach it to this deed. The persons appearing approved, also on behalf of the parties which are represented by them, the entire content of the Reference Deed.

Sale and Purchase Agreement

which is attached as Attachment A to this deed (the “Sale and Purchase Agreement”) and made all declarations contained therein. Where the Sale and Purchase Agreement makes references to the exhibits with the reference numbers listed above, such references are made to the respective exhibits contained in the Reference Deed, except with regard to Exhibit 1.1/1 (Affiliate Agreements). With regard to Exhibit 1.1/1 reference is only made to the exhibit with such reference number contained in this deed.

Instructions by the Notary

The Notary advised the parties particularly about the following:

The correctness and completeness of the corporate information given in the Sale and Purchase Agreement cannot be verified by the Notary and the shareholders list which is available at the competent German commercial register does not necessarily reflect the actual legal situation with respect to the ownership in, the existence of and the nominal amount attributed to the respective GmbH shares.

A shareholder is only considered as owner of a GmbH share by the company if he is listed in the shareholders list kept by the competent commercial register (Sec. 16 para. 1 sent. 1 GmbHG). Prior thereto, the purchaser may not be able to effectively act as shareholder of the GmbH under certain circumstances, and the seller may even be able to still act as shareholder without the consent of the purchaser under certain circumstances.

7/9

A bona fide acquisition (gutgläubiger Erwerb) of GmbH shares by the purchaser is only possible under certain circumstances (Sec. 16 para. 3 GmbHG). GmbH shares which do not exist cannot be acquired in good faith (gutgläubig). Further, the good faith of a purchaser that the acquired GmbH shares are free from any encumbrance is not protected. As long as the seller is registered as shareholder of the GmbH in the shareholders list of the company kept by the competent commercial register, a third party may, by way of a bona fide acquisition, effectively acquire GmbH shares (Sec. 16 para. 3 GmbHG).

With regard to GmbH shares, the purchaser and the seller (though no longer shareholder of the GmbH) are jointly liable for capital contribution obligations of shareholders of the company which are outstanding at the point in time when the purchaser is to be considered owner of the shares by the company (Sec. 16 para. 2 GmbHG). In a GmbH, outstanding capital contribution obligations may be the result of a contribution which has not been fully paid-in, the repayment of capital contributions, or a hidden or overvalued contribution in kind. Under certain circumstances, the other GmbH shareholders are liable for outstanding capital contribution obligations (Sec. 24, 31 para. 3 GmbHG). The purchaser is not protected by his confidence in the correctness of the information given by the seller in this respect.

The acquisition of an (inactive) shell GmbH is regarded as an economic re-formation (wirtschaftliche Neugründung). Even if a currently active GmbH was inactive in the past, the principles for the acquisition of a shell GmbH apply. If the provisions relating to the economic re-formation were/are violated, all shareholders of the GmbH are personally and to an unlimited extent liable for the obligations of the GmbH. The purchaser should, therefore, conduct a careful examination to determine whether an economic re-formation potentially occurred with respect to the purchased GmbH.

Pursuant to Sec. 40 para. 2 GmbHG, the Notary is obliged to file with the commercial register, upon the effectiveness of the GmbH share assignment and transfer without undue delay, a new certified shareholders list indicating the last and first names, birth dates, and places of residence of the shareholders, as well as the nominal amounts and the current numbers of the shares, and, furthermore, send a certified copy of the new shareholders list to the GmbH.

The Notary cannot verify whether the sale of shares in the non-German entities and/or the sale of credit facilities which are not governed by German law pursuant to the attached Sale and Purchase Agreement is valid or has further requirements under applicable foreign law. The persons appearing nevertheless asked for the full recording of the attached Sale and Purchase Agreement.

8/9

All agreements which according to the intentions of the parties shall be part of the overall agreement must completely and duly be notarized. This also applies to ancillary agreements not subject to notarization on a stand-alone basis. A violation of this requirement may cause the entire agreement to be invalid.

The parties hereto will be liable as joint and several debtors for all notarial fees and taxes, if any, by operation of law, irrespective of whatever internal agreement has been made in that respect.

The English language original version of this deed will not be acceptable for enforcement but will have to be translated, by a certified translator, into German for such purposes.

The Notary is obliged to send a certified copy of this deed to the competent tax authorities and only thereafter he is permitted to distribute the original, execution copies or certified copies of this deed to the parties (Sec. 54 EStDV).

The Notary was not requested to examine the tax-related consequences of the legal acts contained in this deed and has, therefore, neither agreed to give, nor has he indeed given, any tax advice. He did, however, point out that the sale of shares in a GmbH may trigger real estate transfer tax (Grunderwerbssteuer), should that GmbH own real estate.

This notarial deed including the attached Sale and Purchase Agreement as well as its exhibits which are not contained in the Reference Deed but which are attached to this deed were read aloud to the persons appearing in the presence of the Notary, approved by the persons appearing and signed by them and the Notary by their own hands as follows:
