Ladies and Gentlemen:

Venator Materials PLC, a public limited company incorporated under the laws of England and Wales (the “Company”), Huntsman International LLC, a Delaware limited liability company (“Huntsman International”), and Huntsman (Holdings) Netherlands B.V., a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) incorporated under the laws of the Netherlands (“Huntsman Holdings” and, together with Huntsman International, the “Selling Shareholders”), confirm their respective agreements with each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 11 hereof), for whom you are acting as representatives (in such capacity, the “Representatives”), with respect to (i) the sale by the Selling Shareholders and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of Ordinary Shares, par value $0.001 per share, of the Company (“Ordinary Shares”) set forth in Schedules A and B hereto and (ii) the grant by the Selling Shareholders to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 3,405,000 additional Ordinary Shares. The aforesaid 22,700,000 Ordinary Shares (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the 3,405,000 Ordinary Shares subject to the option described in Section 2(b) hereof (the “Option Securities”) are herein called, collectively, the “Securities.”

The Company and the Selling Shareholders understand that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (No. 333-217753), including the related preliminary prospectus or prospectuses, covering the registration of the sale of the Securities under the Securities Act of 1933, as

amended (the “1933 Act”). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A (“Rule 430A”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”) and Rule 424(b) (“Rule 424(b)”) of the 1933 Act Regulations. The information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to Rule 430A(b) is herein called the “Rule 430A Information.” Such registration statement, including the amendments thereto, the exhibits thereto and any schedules thereto, at the time it became effective, and including the Rule 430A Information, is herein called the “Registration Statement.” Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein called the “Rule 462(b) Registration Statement” and, after such filing, the term “Registration Statement” shall include the Rule 462(b) Registration Statement. Each prospectus used prior to the effectiveness of the Registration Statement, and each prospectus that omitted the Rule 430A Information that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a “preliminary prospectus.” The final prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Securities, is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system or any successor system (“EDGAR”).

As used in this Agreement:

“Issuer General Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors (other than a “bona fide electronic road show,” as defined in Rule 433 (the “Bona Fide Electronic Road Show”)), as evidenced by its being specified in Schedule C-2 hereto.

(l) Issuer Free Writing Prospectuses. Each of the Company and the Selling Shareholders agrees that, unless it obtains the prior written consent of the Representatives, it will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” or a portion thereof, required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the Representatives will be deemed to have consented to the Issuer Free Writing Prospectuses listed on Schedule C-2 hereto and any “road show that is a written communication” within the meaning of Rule 433(d)(8)(i) that has been reviewed by the Representatives. Each of the Company and the Selling Shareholders represents that it has treated or agrees that it will treat each such free writing prospectus consented to, or deemed consented to, by the Representatives as an “issuer free writing prospectus,” as defined in Rule 433, and that it has complied and will comply with the applicable requirements of Rule 433 with respect thereto, including timely filing with the Commission where required, legending and record keeping. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, any preliminary prospectus or the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(b) Termination of Agreement. If this Agreement is terminated by the Representatives in accordance with the provisions of Section 5, Section 10(a)(i) or (iii), Section 11 (but only with respect to non-defaulting Underwriters) or Section 12 hereof, the Company shall reimburse the Underwriters for all of their reasonable out-of-pocket expenses incurred in connection with the transactions contemplated by this Agreement, including the reasonable fees and disbursements of counsel for the Underwriters.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) under the 1933 Act (each, an “Affiliate”)), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any post-effective amendment thereto), including the Rule 430A Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included (A) in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any post-effective amendment or supplement thereto), or (B) in any materials or information provided to investors by, or with the prior approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission in any preliminary prospectus, Issuer Free Writing Prospectus, Prospectus or in any Marketing Materials of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(e) below) any such settlement is effected with the written consent of the Company and the Selling Shareholders;

(iii) against any and all expense whatsoever, as incurred (including the reasonably incurred fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any post-effective amendment thereto), including the Rule 430A Information, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(b) Indemnification of Underwriters by Selling Shareholders. Each Selling Shareholder severally agrees to indemnify and hold harmless each Underwriter, its Affiliates and selling agents and

each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the extent and in the manner set forth in clauses (a)(i), (ii) and (iii) above; provided, that each Selling Shareholder shall be liable only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any preliminary prospectus, the General Disclosure Package, the Prospectus (or any post-effective amendment or supplement thereto) or any Issuer Free Writing Prospectus in reliance upon and in conformity with the Selling Shareholder Information provided by such Selling Shareholder; provided, further, that the liability under this subsection of each Selling Shareholder shall be limited to an amount equal to the net proceeds to such Selling Shareholder from the sale of Securities sold by such Selling Shareholder hereunder.

(c) Indemnification of Company, Directors and Officers and Selling Shareholders. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and the Selling Shareholders and each person, if any, who controls a Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense (including the reasonable fees and disbursements of counsel) described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any post-effective amendment thereto), including the Rule 430A Information, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(d) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced (through the forfeiture of substantive rights and defenses or otherwise) as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) and 6(b) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(c) above, counsel to the indemnified parties shall be selected by the Company or the Selling Shareholders (as applicable). An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(e) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonably incurred

fees and expenses of counsel in accordance with this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(f) Other Agreements with Respect to Indemnification. The provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to indemnification.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Shareholders, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Selling Shareholders, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Shareholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, (i) no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Shares underwritten by it and distributed to the public and (ii) the Selling Shareholders shall not be required to contribute any amount in excess of the aggregate net proceeds to the Selling Shareholders from the sale of Securities sold by the Selling Shareholders hereunder.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or a Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or the Selling Shareholders, as the case may be. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.

The provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to contribution.

SECTION 8. Tax Indemnity. The Company will indemnify and hold harmless the Underwriters against any documentary, stamp, registration or similar issuance tax, including any interest and penalties (except to the extent attributable to the unreasonable default or delay of the Underwriters in discharging such taxes which have been repaid to the Underwriters or for which the Underwriters have been indemnified), on the execution and delivery of this Agreement, the grant and/or exercise of the option to purchase Option Securities, the sale by the Selling Shareholders of the Securities to the Underwriters, the offer, sale and delivery by the Underwriters of the Securities, and the deposit of the Securities into DTC, as contemplated herein and in the Prospectus.

Any and all amounts payable by the Company or the Selling Shareholders under this Agreement, including any indemnity payments made pursuant to this Section 8, shall be made without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever imposed in any and all relevant taxing jurisdictions unless the Company or any Selling Shareholder is required by law to deduct or withhold such taxes, duties or charges. In that event, and except for any taxes imposed on the Underwriters by any jurisdiction as a result of any present, or former, or future connection (other than any connection resulting from the transactions contemplated by this Agreement) between the Underwriters and the jurisdiction imposing such taxes, the Company or the relevant Selling Shareholder, as applicable, shall pay such additional amounts as may be necessary in order to ensure that the net amounts received after such withholding or deductions shall equal the amounts that would have been received if no withholding or deduction had been made. All sums payable by the Company or the Selling Shareholders under this Agreement to the Underwriters shall be exclusive of value added tax (“VAT”). Where a sum is payable under this Agreement to the Underwriters, the Company or the Selling Shareholders will, in addition to such sum, pay such amount as is equal to any VAT properly chargeable thereon on receipt of a valid VAT invoice. The foregoing provisions shall not apply in respect of any VAT for which the Company is liable to account to the relevant taxing authority directly. All amounts for which the Underwriters are to be reimbursed under this Agreement shall include any applicable VAT included in the relevant cost or expense, except to the extent that the VAT is recoverable.

SECTION 9. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries or the Selling Shareholders submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors, any person controlling the Company or any person controlling a Selling Shareholder and (ii) delivery of and payment for the Securities.

SECTION 10. Termination of Agreement.

(a) Termination. The Representative may terminate this Agreement, by notice to the Company and the Selling Shareholders, at any time at or prior to the Closing Time (i) if there has been, in the judgment of the Representatives, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or (iv) if trading generally on the New York Stock Exchange has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by either Federal, New York or U.K. authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 9, 16, 17 and 18 shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase, and the Company to sell, the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and Huntsman Holdings to sell the relevant Option Securities, as the case may be, either the (i) Representatives or (ii) the Company and the Selling Shareholders shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 11.

SECTION 12. Default by the Selling Shareholders. If a Selling Shareholder shall fail at the Closing Time or a Date of Delivery, as the case may be, to sell and deliver the number of Securities which such Selling Shareholder is obligated to sell hereunder, then the Underwriters may, at the option of the Representatives, by notice from the Representatives to the Company, terminate this Agreement without any liability on the fault of any non-defaulting party except that the provisions of Sections 1, 4, 6, 7, 9, 16, 17 and 18 shall remain in full force and effect. No action taken pursuant to this Section 12 shall relieve a Selling Shareholder so defaulting from liability, if any, in respect of such default.

In the event of a default by a Selling Shareholder as referred to in this Section 12, each of the Representatives and the Company shall have the right to postpone the Closing Time or any Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required change in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements.

SECTION 13. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives as set forth in Schedule A-1; notices to the Company shall be directed to it to 10001 Woodloch Forest Drive, The Woodlands, Texas 77380, attention of Russ R. Stolle (facsimile: (281) 465-6711), with a copy to 1001 Fannin Street, Suite 2500, Houston, Texas 77002, attention of Jeffery B.

Stryker (facsimile: (281) 719-4620), with a copy to 1001 Fannin Street, Suite 2500, Houston, Texas 77002, attention of Jeffery B. Floyd (facsimile: (713) 615 5660).

SECTION 14. No Advisory or Fiduciary Relationship. Each of the Company and each Selling Shareholder acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the initial public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Selling Shareholders, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering of the Securities and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, any of its subsidiaries or the Selling Shareholders, or their respective shareholders, stockholders, creditors, employees or any

other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or the Selling Shareholders with respect to the offering of the Securities or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company, any of its subsidiaries or the Selling Shareholders on other matters) and no Underwriter has any obligation to the Company or the Selling Shareholders with respect to the offering of the Securities except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of each of the Company and the Selling Shareholders, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and each of the Company and the Selling Shareholders has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 15. Parties. This Agreement shall inure to the benefit of and be binding upon each of the Underwriters, the Company and the Selling Shareholders and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and the Selling Shareholders their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and the Selling Shareholders and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 16. Trial by Jury. The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its shareholders and affiliates), the Selling Shareholders and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 17. GOVERNING LAW. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.

SECTION 18. Consent to Jurisdiction; Waiver of Immunity. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. The Company hereby agrees to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in

the City and County of New York at its 10001 Woodloch Forest Drive, The Woodlands, Texas 77380 address. Huntsman Holdings irrevocably appoints Huntsman International at its 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 address as its agent to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the City and County of New York. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

SECTION 19. Judgment Currency. In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency other than United States dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency on the business day preceding that on which final judgment is given. If the U.S. dollars so purchased are less than the sum originally due to such Underwriter hereunder, the Company and the Selling Shareholders agree, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company and the Selling Shareholders (but without duplication) an amount equal to the excess of the United States dollars so purchased over the sum originally due to such Underwriter hereunder. The foregoing indemnities shall constitute a separate and independent obligation of the Underwriters, on the one hand, and the Company and the Selling Shareholders, on the other hand, and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid.

SECTION 20. TIME. TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 21. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

SECTION 22. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company and the Selling Shareholders a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Underwriters, the Company and the Selling Shareholders in accordance with its terms.

Re: Proposed Public Offering by Venator Materials PLC

Dear Sirs:

The undersigned, a shareholder, officer and/or director of Venator Materials PLC, a public limited company incorporated under the laws of England and Wales (the “Company”), understands that Citigroup Global Markets Inc., Goldman Sachs & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC (together, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company, Huntsman International LLC (“HI”), a Delaware limited liability company, and Huntsman (Holdings) Netherlands B.V., a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) incorporated under the laws of the Netherlands (together with HI, the “Selling Shareholders”), providing for the offer and sale by the Selling Shareholders (the “Offering”) of the Company’s ordinary shares, par value $0.32 per share (“Ordinary Shares”). For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement that, during the period beginning on the date hereof and ending on the date that is 180 days from the date of the Underwriting Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of at least three of the Representatives, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of Ordinary Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (collectively, the “Lock-Up Securities”), or exercise any right with respect to the registration of any of the Lock-up Securities, or file, cause to be filed or cause to be confidentially submitted any registration statement in connection therewith, under the Securities Act of 1933, as amended, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Ordinary Shares or other securities, in cash or otherwise.

D-1

If the undersigned is an officer or director of the Company, (1) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of the Lock-Up Securities, the Representatives involved in granting such release pursuant to the terms of this lock-up agreement will notify the Company of the impending release or waiver, and (2) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (i) the release or waiver is effected solely to permit a transfer not for consideration and (ii) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer.

Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer the Lock-Up Securities without the prior written consent of the Representatives, provided that (1) the Representatives receive a signed lock-up agreement for the balance of the Lock-Up Period from each donee, trustee, distributee, or transferee, as the case may be, (2) any such transfer shall not involve a disposition for value, (3) such transfers are not required to be reported with the Securities and Exchange Commission (the “Commission”) on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers during the Lock-Up Period:

(i) as a bona fide gift or gifts; or

(ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin); or

(iii) as a distribution to limited partners or securityholders of the undersigned (as applicable); or

(iv) to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned.

Furthermore, the undersigned may:

(1) sell Ordinary Shares purchased by the undersigned on the open market following the Offering if and only if (i) such sales are not required to be reported in any public report or filing with the Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales;

(2) establish a trading plan pursuant to Rule 10b5-1 under the 1934 Act for the transfer of Ordinary Shares, provided that (i) such plan does not provide for the transfer of Ordinary Shares during the Lock-Up Period and (ii) no public report or filing is required or voluntarily made in connection therewith; and

(3) exercise an option to purchase Ordinary Shares granted under any employee benefit plan, or non-employee director share plan or dividend reinvestment plan, of the Company described in the Registration Statement, provided, however, that (x) the underlying Ordinary Shares received by the undersigned shall continue to be subject to the restrictions on transfer set forth in this lock-up agreement and (y) (i) any filing under Section 16 of the 1934 Act required to be made during the Lock-Up Period

D-2

shall clearly indicate in the footnotes thereto that (A) the filing relates to the circumstances described above and (B) no Lock-Up Securities were sold by the undersigned and (ii) the undersigned does not otherwise voluntarily effect any other public filing or report regarding such transfers during the Lock-Up Period[; and

(4) sell or otherwise transfer Ordinary Shares to one or more direct or indirect wholly-owned subsidiary of Huntsman Corporation (each, a “Permitted Transferee”), with consideration, provided that (x) the underlying Ordinary Shares received by the Permitted Transferee shall continue to be subject to the restrictions on transfer set forth in this lock-up agreement and (y) (i) any filing required to be made during the Lock-Up Period shall clearly indicate in the footnotes thereto that the filing relates to the circumstances described above and (ii) the undersigned does not otherwise voluntarily effect any other public filing or report regarding such transfers during the Lock-Up Period].(1)

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions.

This lock-up agreement shall automatically terminate, and the undersigned shall be released from its obligations hereunder, upon the earliest to occur, if any, of (i) either the Representatives, on the one hand, or the Company or the Selling Shareholders, on the other hand, has advised the other(s) in writing prior to the execution of the Underwriting Agreement that they or it have determined not to proceed with the Offering, (ii) the Company files an application to withdraw the registration statement related to the Offering, (iii) the Underwriting Agreement is executed but is terminated prior to the closing of the Offering (other than the provisions thereof which survive termination) and prior to payment for and delivery of the Ordinary Shares to be sold thereunder, or (iv) January 24, 2018, in the event that the Underwriting Agreement has not been executed by such date.

(1) Applicable to Selling Shareholders only.
