(g) The Parties acknowledge that any rights sublicensed to the Styron Group pursuant to this Agreement are subject to (i) the terms and conditions of the license agreement granting Licensor such sub licensing rights, and (ii) the rights that Dow has previously granted under the Sublicensed Intellectual Property to other Persons. Licensors will use commercially reasonable efforts to prevent the modification, amendment or termination of Styron’s rights under any Sublicensed Contract until Styron receives reasonable prior written notice of such action that provides Styron a reasonable opportunity to consider the impact of such action and (at Styron’s expense) to avoid such amendment, modification or termination. If requested by Styron, Licensors will use commercially reasonable efforts to obtain for Styron the continuation or assignment of such rights at Styron’s cost to the extent practicable under the circumstances.

Section 3.2 If the benefit of a Sublicensed Contract cannot be transferred to the Styron Group except with the consent or approval of a Counterparty or any other Third Party:

(a) this Agreement does not constitute a sublicense or an attempted sublicense of such Sublicensed Contract if the sublicense or attempted sublicense would constitute a breach of such contract;

(b) the Parties hereto shall each use commercially reasonable efforts to obtain such consent or approval to the sublicense in respect of such Sublicensed Contract;

(c) until any consent or approval is obtained or until agreement to any sublicense is achieved, (A) Licensors shall do each act and thing reasonably requested by Styron to enable performance of such Sublicensed Contract by the Styron Group, and to use commercially reasonable efforts to provide to Styron, from the Effective Date, the benefit and the burden of such Sublicensed Contract; and (B) with respect to the period after the Effective Date, as between the Parties, Styron shall, and shall cause its Affiliates to, be responsible for any liabilities arising from or relating to breaches of, or defaults in, such obligations under such Sublicensed Contract and be responsible for, or entitled to, as applicable, any payment (whether by way of deposit, prepayment or otherwise) in respect of the price or cost of any product, service or other benefit provided under such Sublicensed Contract; and

(d) upon any consent or approval to sublicense being obtained, the Parties hereto shall, or shall procure that their respective Affiliates shall, enter into a sublicense in respect of such Sublicensed Contract.

Section 3.3 Subject to the terms of any Sublicensed Contract, the sublicense shall be effective only when executed by a Licensor (or its Subsidiaries) and Styron. After a sublicense is effective under Section 3.1, Styron and its Affiliates shall comply with all obligations in the acknowledgement under Section 3.1(a) and pay all fees that arise from the sublicenses or from operations of Styron and its Affiliates under the Sublicensed Contracts.

Section 3.4 Where applicable, Licensors will allow Styron and Styron’s Personnel to exercise the rights of Licensors and Licensors’ Personnel in the Sublicensed Contracts, and, where consent to the sublicense of a Sublicensed Contract is obtained, consent shall also be obtained to amend references to Licensors or Licensors’ Personnel in such Sublicensed Contract to references to Styron or Styron’s Personnel, as appropriate.

Section 3.5 It is the Licensors’ intent that Appendix 1 lists all license agreements under which Licensors have received licenses or sublicenses from Counterparties with respect to Intellectual Property used, held for use or that is the subject of research or development for the Styron Business (other than contracts assigned or intended to be assigned pursuant to the Sale and Purchase Agreement and agreements that relate exclusively to Excluded IP). The Parties shall notify each other in a timely manner of any omission from Appendix 1 that they discover. If the Parties agree that Appendix 1 is incorrect, they shall immediately execute an amendment to correct the error, such agreement not to be unreasonably withheld, conditioned or delayed, which amendment will have the effect from the Effective Date; provided, that except as otherwise set forth in the Transaction Documents, Licensor shall have no liability for failure of a contract to appear in Appendix 1 as of the Effective Date or for actions taken in good faith prior to such amendment that would have been inconsistent with Licensor’s obligations for the license agreements set forth in Appendix 1 under this Agreement If the Parties dispute in good faith whether an error has occurred, the dispute shall be resolved in accordance with the Service Management Model.

ARTICLE 4. IMPLEMENTATION OF LICENSES

Section 4.1 Styron acknowledges that it has acquired engineering documents and operating manuals in its acquisition of the Styron Business under the Transaction Documents, as well as employees that are experienced in the Licensed Know How. The Parties acknowledge and agree that further disclosures of Licensed Know How may take place (if necessary) under the following conditions:

(a) For [*****] years after the Effective Date, Licensors shall make available to Styron copies of technical documentation in the possession of Dow that relate to the Licensed Know How, including engineering documents, operating manuals, technical reports and laboratory notebooks. Styron will be entitled to one copy, and if available, an electronic copy, at Licensors’ expense, of each such technical document not already in Styron’s possession at the Effective Date, nor available to Styron electronically without Dow’s involvement or assistance. Styron shall bear all costs associated with recovering, copying, translating or delivering further copies of such documentation.

(b) If Personnel of Licensors have knowledge of Licensed Know How that is not available to Styron through its own Personnel, Licensors will make such Personnel reasonably available to Styron, at such times as agreed to by the Parties, to provide technical advice and guidance on the Licensed Know How, under the terms of the Technical Services Agreement or other applicable agreement. Styron shall compensate Licensors for this service as provided under the Technical Services Agreement.

Section 4.2 All disclosures of the Licensed IP and all technical assistance to be provided under this Agreement shall be made or conducted, as the case may be, in the English language, unless the Parties agree to another language.

Section 4.3 Licensors, for themselves and on behalf of Dow, shall prosecute and maintain all registrations and applications to register the Licensed Patents in accordance with Dow’s usual practices.

In the event that Styron at its sole expense avoids any abandonment or lapse of any Licensed Patent pursuant to this Section 4.3, Licensors shall assign (or as applicable cause their Subsidiaries to assign) such Licensed Patent to Styron promptly upon Styron’s request. After such assignment, the Licensed Patent shall be part of the Assigned IP and subject to all relevant terms of this Agreement and the Transaction Documents for Assigned IP.

Section 4.4 Styron shall prosecute and maintain all registrations and applications to register the patents and patents applications included in the Assigned IP, in accordance with Styron’s usual practices. Styron shall (or shall cause any of their Affiliates to) give reasonable notice to Licensors in advance of any non-payment of any maintenance fee, annuity, Tax or other payment necessary to keep such Assigned IP in force, and in advance of any abandonment or lapse of any of such Assigned IP, so as to accord Licensors a reasonable opportunity at their sole expense to make such payment and/or avoid such abandonment or lapse, and Styron agrees to provide reasonable cooperation as shall be reasonably required to effectuate such right. In the event that a Licensor at its sole expense avoids any abandonment or lapse of any patent in the Assigned IP pursuant to this Section 4.4, Styron shall assign such patent to the Licensor promptly upon the Licensor’s request. After such assignment, the patent shall be part of the Licensed IP and subject to all relevant terms of this Agreement and the Transaction Documents for Licensed IP.

Section 4.5 It is the Licensors’ intent that Appendix 2 lists all patents and patent applications owned or controlled by one or more Dow entities to the extent:

(a) used, held for use or the subject of research or development for the Styron Business as of the Effective Date; or

(b) issued or filed after the Effective Date to the extent that the invention upon which such future patent or patent application is based was included in the Licensed Know How and reduced to practice prior to the Effective Date;

in each case of (a) and (b), other than the patents or patent applications or parts thereof included in the Excluded IP and the Assigned IP. The Parties shall notify each other in a timely manner of any correction or update needed in Appendix 2 (either due to omission or over inclusion) that

Amended & Restated Styron License Agreement

16

they discover. If Appendix 2 is incorrect, the Parties shall immediately execute an amendment to correct or update the Appendix, such agreement not to be unreasonably withheld, conditioned or delayed, which amendment will have the effect from the Effective Date; provided, that except as otherwise set forth in the Transaction Documents, Licensor shall have no liability (i) for failure of a patent or patent application to appear in Appendix 2 as of the Effective Date, or (ii) arising out of or relating to Licensors’ use or encumbering a patent or patent application prior to receipt of notice of such error in Appendix 2. If the Parties dispute in good faith whether an error has occurred, the dispute shall be resolved in accordance with the Service Management Model.

ARTICLE 5. TAXES

Section 5.1 The provisions of Article VII of the SPA shall apply mutatis mutandis to all Taxes arising from the license grants and other transactions contemplated in this Agreement as of the Effective Date, and thereafter, the party receiving a royalty shall be responsible for paying all withholding Taxes on any royalties under or pursuant to this Agreement.

ARTICLE 6. EXCLUSION OF OTHER RIGHTS

Section 6.1 Other than the rights to use the Licensed IP and to sublicense the Sublicensed Contracts as expressly provided herein, no license or right is granted herein to Styron with respect to any of Licensors’ Intellectual Property rights or agreements. Other than the rights to use the Assigned IP as expressly provided herein, no license or right is granted herein to Licensors with respect to any of Styron’s Intellectual Property rights or agreements. Specifically, except as set forth in Section 4.5, no right or license is granted herein by any Party with respect to any Intellectual Property developed or acquired after the Effective Date and as between Licensors and Styron, each Party shall have full rights of ownership and enjoyment with respect to such Intellectual Property as between the two with no duty to license or sublicense the other with respect to the same.

ARTICLE 7. ENFORCEMENT OF INTELLECTUAL PROPERTY

Section 7.1 Each Party shall promptly bring to the attention of the other Party any infringement, misappropriation or other violation of the Licensed IP by any Third Party of which it becomes aware (to the extent it has rights to disclose such information). Licensors shall have the exclusive right, but not the obligation, to take enforcement Action against Third Parties after the Effective Date for infringement, misappropriation or other violation of the Licensed IP primarily outside the scope of the Styron Business, at Licensors’ own expense and for Licensors’ own benefit. In the event of such enforcement Action, Licensors shall have the sole right and discretion to select counsel and to conduct and control the litigation (including settlement thereof), and shall be solely entitled to any awards or sums resulting therefrom. Styron shall, at Licensors’ cost, provide any reasonable cooperation that is requested by Licensors in any such Actions, including being joined as a party thereto.

Section 7.2 Styron shall have the exclusive right, but not the obligation, to take enforcement Action against Third Parties after the Effective Date for infringement, misappropriation or other violation of the Licensed IP that is primarily within the scope of the Styron Business, at Styron’s own expense and for Styron’s own benefit. In the event of such enforcement Action, Styron shall have the sole right and discretion to select counsel and to conduct and control the litigation (including settlement thereof), and shall be solely entitled to any awards or sums resulting therefrom. Licensors shall, at Styron’s cost, provide any reasonable cooperation that is requested by Licensors in any such Actions, including being joined as a party thereto.

Section 7.3 If the Parties cannot agree that an infringement, misappropriation or other violation of the Licensed IP by any Third Party is subject to Section 7.1 or Section 7.2, Licensor(s) and Styron shall jointly discuss and agree to a strategy for enforcement of the Licensed IP, including selection of counsel, objectives, milestones, and cost-control. Such legal Action shall be in accordance with the following terms:

(a) Licensor(s) shall file the enforcement Action, and prosecute the Action, in accordance with the agreed strategy.

(d) Within thirty (30) days after any payment in respect of such Action or any judgment thereunder, (i) the proceeds shall first be used to pay for the Parties’ costs of bringing the enforcement Action, and (ii) the applicable Licensor(s) shall then pay to Styron the portion that is attributable to the infringement, misappropriation, or violation of Licensed IP within the scope of the Styron Business. Licensor(s) shall not admit any liability with respect to, or settle, compromise or discharge the claim within the scope of the Styron Business without the prior written consent of Styron, such consent not to be unreasonably withheld, conditioned or delayed.

(e) If Styron elects not to participate in the enforcement Action, Licensors may proceed at their own expense and for their own benefit, and Styron’s obligations to reimburse costs and rights to the recovery shall not apply. Styron shall, at Licensor’s cost, provide any reasonable cooperation that is requested by Licensors in any such Actions, including by providing Licensors with reasonable access to Personnel and documents having information useful to the enforcement Action.

(f) Styron shall not knowingly or intentionally aver or acknowledge contestable facts that Styron knows or should know will significantly weaken or reduce the claim, give rise to counterclaims involving another Party, or support a finding that the Licensed IP is invalid or unenforceable, except as required by applicable Law,

(g) Notwithstanding any other term in this ARTICLE 7, no Party has any duty to initiate or maintain any Action or assert any position that it believes in good faith is contrary to the applicable facts or Law or exposes such Party to unreasonable risk of liability or loss of its Intellectual Property based solely on the merits of the Action.

Section 7.4 Licensor shall promptly bring to the attention of Styron any infringement, misappropriation or other violation of the Assigned IP by any Third Party of which it becomes aware (to the extent it has rights to disclose such information). For the avoidance of doubt, as between the Parties, Styron shall have the exclusive right, but not the obligation, to take enforcement Action against Third Parties after the Effective Date for infringement, misappropriation or other violation of the Assigned IP, and Licensors shall at Styron’s cost provide any reasonable cooperation that is requested by Styron in any such Actions.

Section 8.8 The provisions of this ARTICLE 8 shall be effective to, and only to, the maximum extent, scope and amount permitted by applicable Law, and shall be so construed, interpreted and enforced by any reviewing arbitrator or court. If such provisions are determined to exceed the maximum extent, scope or amount of protection permitted by applicable Law, said provisions shall be construed, interpreted and enforced so as to preserve the maximum protection that is permitted by applicable Law.

Section 8.9

(a) An indemnified Party shall give the indemnifying Party notice of any Action, audit, demand, assessment or other matter which an indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement (each, an “Indemnified Claim”), within [*****] days of such determination, stating the amount of the loss or damage, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises.

(b) If an indemnified Party shall receive notice of any Indemnified Claim within [*****] days of the receipt of such notice (or within such shorter period as may be required to permit the indemnifying Party to respond to any such claim), the indemnified Party shall give the indemnifying Party notice of such Indemnified Claim. The indemnifying Party shall be entitled to assume and control the defense of such Indemnified Claim at its expense and through counsel of its choice if it gives notice of its intention to do so to the indemnified Party within [*****] days of the receipt of such notice from the indemnified Party. If the indemnifying Party elects to undertake any such defense against an Indemnified Claim, the indemnified Party may participate in such defense at its own expense. The indemnified Party shall cooperate with the indemnifying Party in such defense and make available to the indemnifying Party, at the indemnified Party’s expense, all witnesses, pertinent records, materials and information in the indemnified Party’s possession or under the indemnified Party’s control relating thereto as is reasonably required by the indemnifying Party. If the indemnifying Party elects to direct the defense of any such claim or proceeding, the indemnified Party shall not pay, or permit to be paid, any part of such Indemnified Claim unless the indemnifying Party consents in writing to such payment or unless the indemnifying Party withdraws from the defense of such Indemnified Claim liability or unless a final judgment from which no appeal may be taken by or on behalf of the indemnifying Party is entered against the indemnified Party for such Indemnified Claim. If the indemnified Party assumes the defense of any such claim or proceeding pursuant to this Section 8.9 and proposes to settle such claims or proceeding prior to a final judgment thereon or to forgo any appeal with respect thereto, then the indemnified Party shall give the indemnifying Party prompt written notice thereof and the indemnifying Party shall have the right to participate in the settlement or assume or reassume the defense of such claims or proceeding. The indemnified Party shall not admit any liability with respect to, or settle, compromise or

Amended & Restated Styron License Agreement

22

discharge any Indemnified Claim without the indemnifying Party’s prior written consent. The indemnifying Party shall have the right to settle any Indemnified Claim for which it obtains a full release of the indemnified Party in respect of such Indemnified Claim or to which settlement the indemnified Party consents in writing, such consent not to be unreasonably withheld, conditioned or delayed.

Section 8.10 Section 8.10 Each Party shall use its commercially reasonable efforts to mitigate Damages for which it seeks recourse hereunder; provided, that no indemnified Party or their respective Related Persons shall be required to make any claim against its own insurance for any Damages for which they are entitled to indemnification; provided, further, that the failure of such Party to successfully mitigate such Damages shall not affect such Party’s right to seek recourse with respect to such Damages so long as such Party shall have used its commercially reasonable efforts to mitigate and the indemnifying Party cannot show that Damages were the direct result of such failure to mitigate.

Section 8.11 Section 8.11 Any Damages payable under this ARTICLE 8 shall be calculated after giving effect to (i) any insurance payments actually paid to the indemnified Party or any of its Affiliates in connection with the facts giving rise to the right of indemnification, and, if the indemnified Party or any of its Related Persons receives such insurance payment after receipt of payment from the indemnifying Party, then the amount of such insurance payment, net of reasonable expenses incurred in obtaining such recovery or insurance, shall be paid to the indemnifying Party; or (ii) any Tax benefit actually realized by the indemnified Party or any of its Related Persons arising in connection with the accrual, incurrence or payment of any such Damages during the taxable year of such Damages.

Section 8.12 Section 8.12 Regardless of any other rights under any other agreements or mandatory provisions of Law, neither Party shall have the right to set-off the amount of any Claim it may have under this Agreement, whether contingent or otherwise, against any amount owed by such Party to the other Party, whether under this Agreement or otherwise.

ARTICLE 9. SECRECY

Section 9.1 The Parties hereto acknowledge and agree that (a) Sections 1 – 5 and Section 6.6 of the Umbrella Secrecy Agreement (the “Confidentiality Provisions”) are hereby incorporated into this Agreement, and shall apply to the transactions contemplated by this Agreement, mutatis mutandis; and (b) each of the Parties hereto shall be bound by the Confidentiality Provisions in the same manner as if each such Party hereto were a party to the Umbrella Secrecy Agreement.

ARTICLE 10. TERM OF THE AGREEMENT

Section 10.1 From the Effective Date and thereafter, this Agreement amends and supersedes the Previous Agreement in its entirety. The terms of the Previous Agreement govern the rights and obligations of the Parties with respect to the subject matter thereof during the time period from April 1, 2010 until the Effective Date of this Agreement. The terms of this Agreement shall govern the rights and obligations of the Parties with respect to the subject matter hereof (including Licensed IP received by Styron under the Previous Agreement) as of the

Amended & Restated Styron License Agreement

23

Effective Date and thereafter. This Agreement shall continue until the expiration of the last item of Intellectual Property, unless terminated in part earlier under Section 10.3. Notwithstanding anything herein to the contrary, after the expiration of the term under this Section 10.1, the rights and licenses granted in ARTICLE 2 and the sublicenses in ARTICLE 3 shall survive in perpetuity within the same scope as granted within this Agreement; provided, however, that the sublicenses under a Sublicensed Contract shall only survive for the contractual term provided under the applicable Sublicensed Contract.

Section 10.2 If Styron shall commit any material breach of any covenant or term of this Agreement, including the incorporated provisions of Section 9.1, and fails to remedy any such default or breach within [*****] days after written notice thereof by Licensors, Licensors may seek injunctive relief and/or damages, but in no event shall Styron’s rights and licenses under this Agreement terminate. Except in accordance with Section 10.3, the licenses granted by Licensors to Styron hereunder are non-terminable and irrevocable.

Section 10.3 Notwithstanding anything herein to the contrary, if Styron defaults in the performance of its obligations under Section 8.4 on any Action with respect to any product group covered by this Agreement (i.e., styrene monomer, catalyst and polymer products, SAN and ABS products, synthetic rubber products, polycarbonate products, latex products, compounded and blended products, or products other than Styron Products) and such default is not corrected by Styron within [*****] days (or if such default cannot be corrected using commercially reasonable efforts within a [*****] day period, Styron does not take commercially reasonable actions within such [*****] day period, and does not thereafter continue to use commercially reasonable efforts to correct such default) following the date it receives written notice of such default, Licensors may, upon written notice to Styron, terminate Styron’s rights and licenses under this Agreement solely with respect to such product group.

Section 10.4 Notwithstanding anything herein to the contrary, if a Licensor defaults in the performance of its obligations under Section 8.5 on any Action with respect to any product group covered by the license granted to a Licensor to Assigned IP pursuant to Section 2.5 and such default is not corrected by such Licensor within [*****] days (or if such default cannot be corrected using commercially reasonable efforts within a [*****] day period, such Licensor does not take commercially reasonable actions within such [*****] day period, and does not thereafter continue to use commercially reasonable efforts to correct such default) following the date it receives written notice of such default, Styron may, upon written notice to Licensors, terminate Licensors’ rights and licenses under this Agreement solely with respect to such product group.

Section 10.5 Each of the Parties hereto acknowledges and agrees that it would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached and that any non-performance or breach of this Agreement by any Party hereto could not be adequately compensated by monetary damages alone and that the Parties hereto would not have any adequate remedy at Law. Accordingly, in addition to any other right or remedy to which a Party hereto may be entitled, at Law or in equity (including monetary damages), and notwithstanding anything contained herein, such Party shall be entitled to enforce any provision of this Agreement in any court or jurisdiction 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.

Section 11.5 Public Announcement. No Party to this Agreement shall make, or cause to be made, any press release or public announcement in respect of this Agreement or the transactions contemplated hereby or otherwise communicate with any news media regarding this Agreement or the transactions contemplated hereby without the prior written consent of the other Parties unless such press release or public announcement is required by Law or applicable stock exchange regulation, in which case the Parties to this Agreement shall, to the extent practicable, consult with each other as to the timing and contents of any such press release, public announcement or communication; provided, however, that the prior written consent of the other Parties shall not be required hereunder with respect to any press release, public announcement or communication that is substantially similar to a press release, public announcement or communication previously issued with the prior written consent of the other Parties.

Section 11.6 Headings and References; Construction. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. When a reference is made in this Agreement to an Article, a Section or an Appendix, such reference is to an Article, a Section of, or an Appendix to, this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they are deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import, when used in this Agreement, refer to this Agreement as a whole and not to any particular provision of this Agreement. All terms defined in this Agreement have the defined meanings when used in any certificate or other document made or delivered pursuant hereto, unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. References to a Person are also to its successors and permitted assigns. The use of “or” is not intended to be exclusive unless expressly indicated otherwise. The word “shall” indicates that the named action or inaction is compulsory, and the word “may” indicates that the named action or inaction is within the discretion of the Party. If there is any conflict between the Sale and Purchase Agreement and this Agreement, each of the Sale and Purchase Agreement and this Agreement is to be interpreted and construed, if possible, so as to avoid or minimize such conflict, but, to the extent (and only to the extent) of such conflict, the Sale and Purchase Agreement shall prevail and control.

Section 11.7 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

Amended & Restated Styron License Agreement

26

provisions of this Agreement shall 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 the Parties hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible.

Section 11.8 Entire Agreement. This Agreement and the Transaction Documents constitute the entire agreement of the Parties hereto with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, between the Parties hereto with respect to the subject matter hereof.

Section 11.9 Assignment

(a) This Agreement may not be assigned by operation of Law or otherwise without the express written consent of the other Parties hereto (which consent may be granted or withheld in the sole discretion of such Parties), as the case may be, and any, attempted assignment without such consent shall be null and void; provided, however, that each Licensor shall be permitted to assign its rights hereunder to any of its Affiliates; provided, further, that no such assignment shall relieve such Licensor of its obligations hereunder.

(b) Notwithstanding the foregoing, the relevant rights and obligations pursuant to this Agreement may be assigned or transferred divisibly by each Licensor to any Third Party without the consent of Styron in connection with a sale by such Licensor of:

(1) all or substantially all of the assets or properties of Licensor to which the subject matter of this Agreement relates; and/or

(2) any part of the foregoing assets or properties to which the subject matter of this Agreement relates, including a business or business unit of Licensor, in which case Licensor may only assign such rights and obligations pursuant to this Agreement as may be related to such part;

provided, in either case, that such Third Party assumes the Licensor’s obligations hereunder (or, if transferred divisibly, assumes the applicable part of Licensor’s obligations hereunder) and accepts any of Licensor’s Owned or Controlled IP subject to the terms of this Agreement.

(c) Notwithstanding the foregoing, the relevant rights and obligations pursuant to this Agreement may be assigned or transferred divisibly by Styron to any Third Party in connection with a sale by Styron of:

(1) all or substantially all of the assets or properties of Styron or its Affiliates to which the subject matter of this Agreement relates; and/or

(2) any part of the foregoing assets or properties to which the subject matter of this Agreement relates, including a business or business unit of Styron or its Affiliates, in which case Styron may only assign such rights and obligations pursuant to this Agreement as may be related to such part;

Amended & Restated Styron License Agreement

27

provided, however, that Styron may not assign this Agreement, in whole or in part, without Licensors’ consent in connection with Styron’s sale of a facility, plant or business unit if the prospective purchaser already operates similar facilities, plants or business units with a different technology, until the Licensors and the prospective purchaser enter into a written agreement that would prevent the co-mingling of their technologies. Any Third Party that receives an assignment or transfer of Intellectual Property rights under this Agreement must agree to be bound by Styron’s obligations hereunder with respect to such Intellectual Property (or, if transferred divisibly, must agree to be bound by the applicable part of Styron’s obligations hereunder). Styron will give Licensors notice of an assignment under this Section 11.9(c) no later than the later of (i) [*****] days prior to the assignment; or (ii) when Styron has rights to disclose the assignment to Licensors, but in no event later than the public announcement of the underlying transaction.

(d) Upon the assignment of this Agreement and the express assumption by the assignee or transferee of the assigned obligations of the applicable Party under this Agreement through the execution of an assignment and assumption agreement, the applicable Party shall be fully and unconditionally released:

(1) in the case of an assignment of this Agreement, from all obligations and liabilities under this Agreement except ARTICLE 9; and

(2) in the case of an assignment of certain rights and the assumption of certain obligations pursuant to Section 11.9(b) or Section 11.9(c), from all obligations and liabilities under this Agreement with respect to such rights and liabilities except ARTICLE 9.

(e) Styron may assign this Agreement and all of its rights and obligations under this Agreement to any Affiliate that is substantially owned, directly or indirectly, by the same Person as Styron with notice to TDCC, provided the Affiliate expressly assumes (in writing to TDCC) all of Styron’s obligations hereunder.

Section 11.10 Amendment. This Agreement may not be amended or modified except (a) by an instrument in writing signed by, or on behalf of, the Parties hereto that expressly references the Section of this Agreement to be amended; or (b) by a waiver in accordance with Section 11.11.

Section 11.11 Waiver. Any Party to this Agreement 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 the representations and warranties of the other Parties contained herein or in any document delivered by the other Parties 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 shall be valid only if set forth in an instrument in writing signed by the Party or Parties to be bound thereby. Any waiver of any term or condition shall not 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 hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights.

Section 11.12 No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the Parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer 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.

Section 11.13 Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of New York, without giving effect to principles of conflicts of laws or principles that might refer the governance or construction of this Agreement to the law of another jurisdiction. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in the Delaware Court of Chancery; provided, however, that if such court does not have jurisdiction over such Action, such Action shall be heard and determined exclusively in any Delaware state court or United States federal court sitting in the State of Delaware or in the Borough of Manhattan of The City of New York. Consistent with the preceding sentence, the Parties hereto hereby (a) submit to the exclusive jurisdiction of the Delaware Court of Chancery or, if such court does not have jurisdiction, any Delaware state court or United States federal court sitting in the State of Delaware or in the Borough of Manhattan of The City of New York, for the purpose of any Action arising out of or relating to this Agreement brought by either Party hereto; and (b) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated by this Agreement may not be enforced in or by any of the above-named courts. The foregoing shall not, however, limit either Party’s right to seek equitable relief as set out in Section 10.5.

Section 11.14 Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTION OR LIABILITY DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH OF THE PARTIES HERETO HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY SUCH ACTION OR LIABILITY, SEEK TO ENFORCE THE FOREGOING WAIVER; AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.14.

Section 11.15 Counterparts. This Agreement may be executed and delivered (including by facsimile or other means of electronic transmission, such as by electronic mail in “pdf” form) in one or more counterparts, and by the different Parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.

This Appendix 5 is intended to contain a complete listing of all Dow Products commercially sold prior to the Effective Date that are not Styron Products and are End Uses of Styron Products. The End Uses of Styron Products that are set forth in this Appendix 5 and any amendments hereto are intended to include and extend only to the particular formulations that are described (or if not described, then only those formulations that are actually used in the identified Dow Products as of the Effective Date), and are not intended to include classes of products, markets, or similar products that may contain different formulations. The Parties shall notify each other in a timely manner of any error in this Appendix 5 (either by omission or over inclusion) that they discover.

(1) If Appendix 5 is incorrect, the Parties shall immediately execute an amendment to correct the error, such agreement not to be unreasonably withheld, conditioned or delayed. If the Parties dispute in good faith whether an error has occurred, the dispute shall be resolved in accordance with the Service Management Model.

(2) The amendment will have the effect from the date of the notice provided above, except that Styron shall have no liability for disclosure, licensing or use of the non-licensed End Use in good faith before the relevant notice date and shall be permitted to continue support for such End Use with customers who received a license to such End Use before the notice date.

(3) This Appendix, 5 and any amendments to it shall not restrict the use of emulsion polymers by Styron or its licensees in the following markets: (a) coated paper; (b) coated paperboard; (c) carpet; and (d) tires.
