The Styron Parties, Sumitomo and SDL hereby agree that: 
 (a) In the event of a Change of Control (as defined below) in any Styron Party or Sumitomo Party (each such Styron Party or Sumitomo Party undergoing a Change of Control, an “Affected
Party”), the other party to SDL (the holder of Sumitomo’s common stock of SDL in the event that a Styron Party is the Affected Party and the holder of Styron BV’s common stock of SDL in the event that a Sumitomo Party is the
Affected party, the “Option Party”) has the right (“Option”) (i), in the event that the Option Party is a Sumitomo Party, to purchase all, but not less than all, of the common stock of SDL held by the Affected
Holder (as defined below), or (ii), in the event that the Option Party is a Styron Party, to purchase all, but not less than all, of the common stock of SDL held by the Affected Holder, in each case on the terms set out in this

the Affected Holder shall sell the Option Shares to the Option Party, and the Option Party shall purchase the Option Shares for the Option Price, free from all liens, charges and encumbrances and third party rights, but together with all rights of
any nature attaching to them, including, but not limited to, all rights to any dividends or other distributions declared, paid or made after the date of giving the Option Notice. 

(e) The closing of the sale and purchase of the Option Shares pursuant to this Section 8 is to take place at the office of

13. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by
any Law or public policy, all other terms and provisions of this Agreement nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner
materially adverse to either Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent
of the Parties as closely as possible in a 

  
 9 








 
mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible. 

14. Assignment. No Party may assign this Agreement or any of its rights hereunder, whether by operation of Law or
otherwise, or delegate any performance under this Agreement, in each case without the express written consent of each other Party (which consent may be granted or withheld in the sole discretion of such Parties). Any attempted assignment or

16. Waiver. Any Party may (a) extend the time for the performance of any of the obligations or other acts of the other
Parties; (b) waive any inaccuracies in any representation or warranty of any other Party contained herein or in any document delivered by any other Party pursuant hereto; or (c) waive compliance with any of the agreements of the other
Parties or conditions to such Parties’ obligations contained herein. Any such extension or waiver is valid only if set forth in an instrument in writing signed by the Party to be bound thereby. Any waiver of any term or condition is not to be
construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of any Party to assert any of its rights hereunder does not constitute a
waiver of any of such rights. 
 17. Specific Performance. The Parties acknowledge and agree that the Parties
would be irreparably damaged if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that any non-performance or breach of this Agreement by any Party could not be
adequately compensated by monetary damages alone and that the Parties would not have any adequate remedy at Law. Accordingly, in addition to any other right or remedy to which any Party may be entitled, at Law or in equity (including monetary
damages), such Party is entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this
Agreement without posting any bond or other undertaking. The Parties agree that they will not contest the appropriateness of specific performance as a remedy. 
 18. No Third Party Beneficiaries. This Agreement is binding upon and inures solely to the benefit of the Parties and their respective successors and permitted assigns, and nothing herein,
express or implied, confers upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement. 

19. Governing Law; Arbitration. This Agreement and any agreement entered into pursuant to this Agreement (except to the
extent provided specifically otherwise in such agreement) is governed by, and interpreted as to all matters, including validity, construction and performance, by and under the laws of Japan. All disputes concerning the construction and performance
of this Agreement or agreements entered into pursuant hereto are to be exclusively 

  
 10 









 
and finally settled by arbitration in any location in New York, New York, U.S.A. or Tokyo, Japan, as elected by the responding party, under the then current Rules of Conciliation and Arbitration
of the International Chamber of Commerce, Paris, France, by three arbitrators appointed in accordance with such rules. 
 20.
Counterparts. This Agreement may be executed and delivered (including by facsimile transmission or transmission of a Portable Document Format (.pdf) file) in one or more counterparts, and by the different Parties in separate counterparts,
each of which when executed is deemed to be an original, but all of which taken together constitute one and the same agreement. 

21. Schedules and Exhibits. Unless otherwise expressly stated herein, any reference to a Schedule refers to the applicable
Schedule attached hereto, and any reference to an Exhibit refers to the applicable Exhibit attached hereto, with all the Schedules and Exhibits being incorporated herein and made a part of this Agreement by this reference.

	13.03	NEWCO shall enter into an export sales agreement with DOW, or one or more of DOW’s designated Subsidiaries, appointing DOW and/or said Subsidiaries as the major
distributor with respect to export from Japan of PC Resin and PC Products, unless DOW should elect otherwise. DOW’s primary focus as the major distributor to NEWCO shall be on the handling of non-J-OEM export business. The definition of J-OEM
and DOW’s role as the “major” distributor shall be clarified in the export sales agreement. The agreement shall be renewed annually, upon approval of its terms by NEWCO’s Board. DOW shall provide the distribution services to
NEWCO hereunder at a competitive margin as specified in the agreement NEWCO shall elect to use DOW export channels for sales to J-OEM in Asia, where such DOW channels are capable of benefiting NEWCO through satisfactory customer services and cost
efficiency. 

 Other export channels may be used, where the total combined sales of NEWCO through domestic, J-OEM
and DOW export channels are insufficient to ensure reasonable plant capacity utilization, or where exceptionally required for NEWCO to capture an additional, specific business opportunity. Such matter will first be discussed and agreed by the
Steering Committee. 
  

	13.04	 Upon request of DOW, and to the extent NEWCO will not face undue hardship thereby, NEWCO will, because of NEWCO’s expertise in the area of
marketing to Japanese companies, assist DOW in obtaining acceptance, qualification and/or approval for certain of DOW’s PC Resin and PC Products by the headquarters of Japanese companies designated by DOW, for the purpose of possible sales of
such products by DOW to such Japanese companies’ subsidiaries who have use for the same

shall enter into a separate commission agreement Upon DOW’s obtaining such acceptance, qualification and/or approval for DOW products as a result of said assistance rendered by NEWCO (as and to be defined in such agreement), DOW shall pay NEWCO
a commission of: 


  

	 	(1)	three percent (3%) on the sales value of DOW products that are developed and specified by NEWCO (all as determined by the criteria and definitions to be included
in the agreement), or 

  

	 	(2)	two percent (2%) on the sales value of DOW products that are developed by DOW or its Subsidiaries and specified by NEWCO (all as determined by the criteria and
definitions to be included in the agreement).

defined in the Technology Agreement for manufacture of PC Resin and/or PC Products to a third party in the Territory as defined in the Technology Agreement, DOW shall first consult with NEWCO. 


Section 14 Major Raw Materials for PC Resin (Bisphenol-A and Methylene Chloride) 

 

	14.01	DOW (directly and/or through its Subsidiaries) shall continue to have the right to supply either or both of bisphenol-A and methylene chloride to NEWCO, and the terms

conditions, in terms of quality, terms of payments and other standard contractual terms and conditions; and 

  

	 	(6)	shall not be connected with payment of any consideration to the third party by NEWCO or vice versa, and shall not otherwise be the subject of any collusion that results
in the offer not being an armslength offer, 

 then DOW shall notify NEWCO in writing within three (3) months
after receipt of such notice of NEWCO its intention either to (i) reduce its price to the price offered by the third party for the equivalent period, assuming there is no intervening material change in circumstances which affects the validity
of the third party offer, or (ii) maintain the price determination process and method under the Supply Agreement. NEWCO shall then continue purchasing from DOW, in the case of (i) above, 100% of its total requirement for bisphenol-A, or in
the case of (ii) above, 50% of its total requirement. In the latter case, DOW’s right to supply 50% of NEWCO’s requirement shall continue for one (1) year

after the commencement of the supply by the third party to NEWCO, which shall become effective three (3) months after DOW notified NEWCO of its intention as described above. Following the
said one (1) year period, DOW shall have the option to continue supply either (i) 100% of NEWCO’s total requirement on an ongoing basis, or (ii) 50% or less of NEWCO’s total requirement as elected by DOW for a specified

no intervening material change in circumstances which affects the validity of the third party offer. The right of NEWCO to present to DOW a third party offer under this section may be exercised no more than once a year with an interval of at least
eleven (11) months from the previous occasion. NEWCO shall not disclose DOW’s actual supply prices or price determination mechanism to any third party for any reason for an indefinite period.

	15.03	Each service providing party and NEWCO shall execute a service agreement containing terms and conditions of provision of services, which terms and conditions shall in

 Section 17 Support by SUMITOMO and DOW for Future NEWCO Fund Raising 
  

	17.01	NEWCO shall be responsible for obtaining the funds necessary for its operations and shall be free to adopt any method or scheme that it deems most beneficial to raise
