Non-Recourse Accounts Receivable Purchase Agreement dated May 31, 2020 and amend

The Purchaser will maintain a Current Account reflecting Seller's financial position with regard to the purchased Eligible Receivables and the respective purchase price paid by the Purchaser thereto as reflected in the books of the Purchaser. Although the Purchaser will maintain separate sub-accounts, all such accounts established in the books of the Purchaser are to be considered as part of one indivisible account subject to the Maximum Program Amount.

Relevant Nominating Body means any applicable central bank, regulator or other supervisory authority or a group of them, or any working group or committee sponsored or chaired by, or constituted at the request of, any of them or the Financial Stability Board.

3.1 The Seller hereby sells to the Purchaser certain Eligible Receivables designated by Seller defined under Eligible Debtors in accordance with the provisions of article 1689 and following of the Belgian Civil Code so that such Eligible Receivables purchased hereunder vest in the Purchaser absolutely. The Purchaser may at any time assign, transfer or participate any of its rights in such Eligible Receivables.

3.2 The Purchaser hereby agrees to accept at its sole discretion and on an uncommitted basis such transfer and assignment subject to the terms and conditions of this Agreement.

3.3 The Parties agree that as of the Effective Date their respective systems and processes are configured such that each Party can promptly, readily and accurately identify receivables purchased and sold hereunder at the invoice level.

3.4 After the supply of goods to the Eligible Debtors, the Seller will send the original invoice to such respective Eligible Debtor and, upon first written demand of the Purchaser, one copy thereof to the Purchaser.

3.5 The Seller hereby engages itself to transfer its invoice listings, debtor's data and overviews of outstanding assigned Eligible Receivables (the "Ledger") electronically to the Purchaser thereby using the Webservice made available to the Seller by the Purchaser for the purpose of this Agreement.

3.7 For the avoidance of doubt, only the entire receivable under an individual invoice is sold and purchased hereunder, and under no circumstances shall a partial interest in a receivable under an individual invoice be sold or purchased hereunder.

3.8 In the event the Seller reconciles a receivable matter with a credit memo, such credit memo shall be treated as an invoice hereunder. Credit memos issued on or after the Effective date are considered eligible credit memos under this agreement.

4.1 The "Discount" to which the Purchaser is entitled amounts to 0.02 % of all accounts receivable transferred to the Purchaser in accordance with the terms and conditions of this Agreement and is reflected in the Purchase Discount Fee as defined in article 6.2. of this Agreement.

4.2     Additional Discount

4.2.1. In addition, in exchange for the Purchaser assuming the risk of loss with respect to the accounts receivable transferred to the Purchaser by the Seller in accordance with this Agreement, the Purchaser shall be entitled to an additional discount (the "Additional Discount"), amounting to 0.06% of the accounts receivable assigned to the Purchaser for which the insolvency risk coverage is governed by the terms and conditions of this Agreement, in particular as stipulated in article 7.1. The Additional Discount is reflected in the Purchase Discount Fee as defined in article 6.2. of this Agreement.

4.3.1. The Parties acknowledge that the Purchaser may be forced, by external (cost-related) developments to increase the Additional Discount, as set forth in article 4.2. However, the Purchaser shall not be permitted to increase the Additional Discount more than once per factoring year.

The Purchaser shall inform the Seller of such a decision immediately by registered mail thereby documenting the developments that led to the Purchaser's decision. During a period of 90 days after receipt of such letter, the Parties, both acting in good faith, will conduct mutual negotiations with regard to the Purchaser's decision. During the same period of 90 days after receipt of such letter, the Seller has the right to terminate this Agreement by informing the Purchaser by registered mail, thereby providing the Purchaser with a notice period of 90 days during which this Agreement shall remain in force and effect. In the event the Seller does not provide the Purchaser with such registered letter as stipulated in this article, the changes made by the Purchaser shall be deemed accepted by the Seller.

4.3.2. The Parties hereby agree that the Purchaser has the right to increase the margin, as reflected by "M" in the Discount Fee stipulated in article 6.2., in accordance with the provisions of this article.

Notwithstanding the foregoing (i) no such increase shall modify the purchase price with respect to accounts receivable that have been sold prior to the effective date of such increase, and (ii) all changes in liquidity premium possibly to be charged by the Purchaser onwards to the Seller as referenced in this article, shall be communicated by the Purchaser during the month before the month in which such changes would come into effect.

The Parties hereby agree that, the liquidity premium charged to the Purchaser, shall be charged onwards by the Purchaser to the Seller. However, the Parties hereby agree that Purchaser shall only be entitled to charge such liquidity premium to the Seller as from the moment such liquidity premium charged to the Purchaser is equal or higher than 0.25%. In such event, the liquidity premium charged by the Purchaser to the Seller shall be equal to the difference between said 0.25% threshold and the liquidity premium actually charged to the Purchaser.

However, the Parties hereby agree that, in the event the liquidity premium charged to the Purchaser would, at any time, become higher than 0.75%, and as a result thereof the liquidity premium charged onwards to the Seller by the Purchaser would become higher than 0.50%, the Purchaser will inform the Seller of such a situation by registered letter. During a period of 90 days after receipt of such letter, the

Parties, both acting in good faith, will conduct mutual negotiations with regard to this situation. During the same period of 90 days after receipt of such letter, the Seller has the right to terminate this Agreement by informing the Purchaser thereof by registered mail thereby providing the Purchaser with a notice period of 90 days during which this Agreement shall remain in force. In the event the Seller does not provide the Purchaser with such registered letter as stipulated in this article, the changes made by the Purchaser shall be deemed accepted by the Seller.

4.4.1 The Parties agree that the purchase price for the accounts receivable reflects a market rate fee to the Seller for continued servicing of the accounts receivable by Seller or its affiliate. If, at any lime during the term of this Agreement, the Purchaser takes over the dunning from the Seller, an amount of 5 USO per booked invoice or credit note will be charged to the Seller.

4.4.3 The Parties agree that, bank account(s) used for servicing hereunder may be owned and controlled by Seller or the Seller affiliate primarily handling such servicing, and Seller or the servicer may change such account from time to time with notice to Purchaser. Purchaser shall be entitled to require a deposit account control agreement (DACA) or similar agreement to be executed between the entity owning the servicing account and the Purchaser.

4.5 The Purchaser shall be entitled to an audit fee amounting to 800 USO per year and the whereby Parties hereby agree that the Purchaser shall be entitled to perform such audit of the procedures of the Sellers with a frequency of 1 audit per year. Additional reporting from the Seller may be required by the Purchaser in between consecutive audits.

The Parties acknowledge that a minimum volume of receivable purchase and sale transactions per year is commercially necessary to warrant continued administration of this program by the Parties. Although this program is an uncommitted facility, for each of calculation the Parties agree to measure the minimum volume of transactions by measuring the minimum factor discount charged by Purchaser over the course of a year under the program. The minimum factor discount (which shall equal the sum of the Discount and the Additional Discount) will not be lower than 250,000 USO per year and shall be considered as a minimum factor discount calculated jointly for this Agreement and the Flexsys America L.P. Agreement, the Solutia Inc. Agreement, and the Eastman Chemical Ltd. Agreement together. This minimum factor discount is calculated from the start of every factoring year and is due for payment at the end of every factoring-year, factoring-year meaning every period of 12 months from the Effective Date as defined in this Agreement. The amount payable with respect to the minimum factor discount will be the difference between 250,000 USO and the sum of the Discounts and the Additional Discounts for all accounts receivable sold during the applicable factoring year. In the event either Party reasonably determines that the volume of receivable purchase transactions hereunder is unlikely to achieve the minimum factor discount for the year, either Party may give notice to terminate the program within ninety (90) days of the notice. In the event of a termination by either Party on account of low volume of receivables purchase activity, the minimum factor discount shall be prorated accordingly.

6.1 The Parties hereby agree that, on a Seller's request, the Purchaser, thereby debiting the Seller's sub account within the Current Account, will pay the purchase price of the Eligible Receivables (incl. VAT) sold to it in accordance with article 3.1 of this Agreement in accordance with the discount formula as agreed upon in article 6.2 within: (i) the limits of the available room under the Maximum Program Amount: and (ii) the credit limits on the Eligible Debtor as issued by the Purchaser: (iii) insofar as an

Eligible Receivable entirely falls within this credit limit. The Parties hereby agree that such payment shall be made by the Purchaser on the bank accounts of the relevant Seller as indicated by that Seller whereby the sale of the respective Eligible Receivable shall become effective as from the moment the Purchaser has paid to the Seller the respective purchase price thereof. The purchase price shall be paid to the relevant Seller on the Purchase Date.

6.2 Purchase Price for the Sold Accounts Receivable - Discount Fee

6.3 The Purchaser will charge the Purchaser a one-off starting fee of 5000 USO at the Effective Date of this Agreement.

6.4 In the event, in the Purchaser's reasonable opinion, the portfolio of assigned Eligible Receivables in relation to a Seller does not provide the Purchaser with sufficient comfort with regard to the payment of the Purchase Price paid, the Purchaser has the right to suspend the program in relation to that Seller by informing the relevant Seller thereof by registered letter, whereupon the Purchaser shall not be obliged to purchase any future Eligible Receivables from that Seller. Any exercise by the Purchaser of its discretion under this clause shall in no way affect the Parties obligations in relation to Eligible Receivables purchased by the Purchaser prior to the date of the notice served in accordance with this clause.

6.5 The Parties agree that, in order for a transferred account receivable to be eligible for purchase under this Agreement, the debtor with regard to such account receivable may not represent a concentration of more than 10% of the amount of the approved outstanding accounts receivable on all debtors assigned to the Purchaser (excluding any Outstanding Receivables in all instances).

6.6 The Parties agree that confirmed letters of credit shall not constitute accounts receivable hereunder and that therefore accounts receivable secured by confirmed letters of credit shall not be sold, nor purchased under this Agreement.

6.7 The Parties agree that invoices eligible for early pay discount with Seller shall not constitute accounts receivable hereunder, therefore such invoices shall not be sold, nor purchased under this Agreement.

6.8 The Parties agree that the Seller may provide credit rebates on outstanding accounts receivable in the ordinary course of its business and consistent with customary practice through use of credit memos (which credit memos shall be treated as invoices hereunder), and the final payments with respect to any such diluted receivables will be reduced by the amount of such dilution; provided, however, that any write off or compromise of an account receivable as a result of the insolvency or credit status of the debtor shall not constitute dilution hereunder. In the event the dilution in the debtor portfolio (dilution being amounts not paid by the respective debtor to the Factor due to credit notes, disputes, payments made on the bank account of the Seller) should exceed the 3% dilution level, the percentage of the purchase price with regard to Sold Accounts Receivable, shall be decreased by the percentage exceeding said 3% limit.

Up to the amount of the credit limit as provided by the Purchaser, the Purchaser will assume the insolvency and non-payment risk on the Eligible Debtors as from the moment the goods related to a certain Eligible Receivable have been dispatched by the Seller for delivery to the Eligible Debtor and subject to the conditions that:

•the delivery of the goods to the Eligible Debtor was performed (i) before bankruptcy of the Eligible Debtor, and (ii) before the Eligible Debtor is failing to pay Seller's outstanding invoices within a period of 90 days after their respective due dates.

In any event the following situations of non-payment by an Eligible Debtor are excluded from any risk coverage by the Purchaser:

8.1 The Parties hereby agree that the Seller will perform the collection of the purchased Eligible Receivables (the "Dunning Mandate"), directly or indirectly through one or more Affiliates of Seller, and that all payments made by the Eligible Debtors with regard to assigned Eligible Receivables shall be made on the bank accounts of the Seller. In the event the Debtors do not specify which invoice(s) any such payment represents, such payment(s) will be applied to invoices in order of earliest invoice date.

The Parties agree that this Dunning Mandate can only be terminated if a covenant stipulated in section 9 (Covenants) is breached or at the request of the Seller. If requested, the Purchaser may request transfer of the Dunning Mandate for accounts receivable that are transferred.

The Parties further agree that the payments of the debtors received by the Seller will be transferred towards the Purchaser on a bi-weekly basis. The Parties are entitled to change this transfer of received payments by a settlement in the Current Account. This can be agreed between Parties in writing.

Consolidated Solvency on group level of the Eastman Chemical Company, calculated as:

Equity/ Total Assets not adjusted with goodwill and intangible assets

Whereby the solvency must remain above:

20% in order to maintain the confidential character of this Agreement; otherwise, the Purchaser may notify the Seller's debtors of the existence of this Agreement; and

16% in order to maintain the Dunning Mandate as granted by the Purchaser to the Seller; otherwise the Purchaser has the right to take over the collection of the purchased Eligible Accounts Receivable.
