 Exhibit 10.15 
 INDEMNIFICATION AGREEMENT 
 This Indemnification Agreement (this
“Agreement”) is made as of [DATE] (the “Effective Date”) by and between Neustar, Inc. (the “Company”), and [NAME] a director or officer of the Company (“Indemnitee”). 

BACKGROUND 
 A. The Board has determined that the Company’s ability to attract and retain qualified persons as directors and officers is in the best interests of the Company’s stockholders and that the
Company should act to assure such persons that there will be adequate certainty of protection through insurance and indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf
of the Company. 
 B. The Company has adopted provisions in its Certificate of Incorporation and bylaws providing for
indemnification of, and payment of expenses to, its directors and officers to the fullest extent authorized by the Delaware General Corporation Law, and the Company wishes to clarify and enhance the rights and obligations of the Company and
Indemnitee with respect to indemnification and payment of expenses. 
 C. In order to induce and encourage highly experienced
and capable persons such as Indemnitee to serve and continue to serve the Company as directors, officers and/or in any other capacity, and to otherwise promote the desirable end that such persons will resist what they consider unjustified lawsuits
and claims made against them in connection with the good-faith performance of their duties to the Company, with the knowledge that certain costs, judgments, penalties, fines, liabilities and expenses incurred by them in their defense of such
litigation are to be borne by the Company and they will receive the maximum protection against such risks and liabilities as may be afforded by law, the Board has determined that the following Agreement is reasonable and prudent to promote and
ensure the best interests of the Company and its stockholders. 
 D. The Company desires to have Indemnitee continue to serve as
a director or officer of the Company and/or in such other capacity with respect to the Company as the Company may request, as the case may be, free from undue concern for unpredictable, inappropriate or unreasonable legal risks and personal
liabilities by reason of Indemnitee acting in good faith in the performance of Indemnitee’s duty to the Company, and Indemnitee desires to continue so to serve the Company, provided, and on the express condition, that he or she is furnished
with the indemnity set forth hereinafter. 
 AGREEMENT 

Now, therefore, in consideration of Indemnitee’s continued service for the Company, the parties hereto agree as follows: 

1. Service by Indemnitee. Indemnitee will serve and/or continue to serve as a director or officer of the Company and/or in such
other capacity with respect to the Company as the Company may request, as the case may be, faithfully and to the best of Indemnitee’s ability so long as Indemnitee is duly elected or appointed and until such time as Indemnitee is removed as
permitted by law or tenders a resignation in writing. 

 2. Indemnification and Payment of Expenses. The Company shall indemnify
Indemnitee, and shall pay to Indemnitee in advance of the final disposition of any Proceeding all Expenses incurred by Indemnitee in defending any such Proceeding, to the fullest extent authorized by the Delaware General Corporation Law in effect on
the date hereof or as such law may from time to time be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader rights than said law permitted the Company to provide prior to
such amendment), all on the terms and conditions set forth in this Agreement. Without diminishing the scope of the rights provided by this Section, the rights of Indemnitee provided hereunder shall include but shall not be limited to those rights
hereinafter set forth, except that no indemnification or advancement of Expenses shall be paid to Indemnitee: 
 (a) to the extent expressly prohibited by applicable law or the Certificate of Incorporation or bylaws of the Company, in each case as in effect on the date hereof or as such law, Certificate of
Incorporation or bylaws, as the case may be, may from time to time be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader rights than said law, Certificate of Incorporation
or bylaws, as the case may be, permitted the Company to provide prior to such amendment); 
 (b) for which
payment has actually been made to Indemnitee under a valid and collectible insurance policy or under a valid and enforceable indemnity clause, provision of a certificate of incorporation or bylaw, or agreement of the Company or any other company or
organization on whose board Indemnitee serves at the request of the Company, except with respect to any deductible (or the equivalent) from or excess beyond the amount payable or paid under any insurance policy or other indemnity provision (and
Indemnitee shall reimburse the Company for any amounts paid by the Company and subsequently so recovered by Indemnitee); 
 (c) for an accounting of profits made (i) from the purchase and sale (or sale and purchase) by the Indemnitee of securities of the Company within the meaning of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or similar provisions of state statutory law or common law, or (ii) from any transactions prohibited under Section 306(a) of the Sarbanes-Oxley Act of 2002; 

(d) in connection with any action, suit or proceeding (or any part thereof), including claims and counterclaims, initiated
or brought voluntarily by Indemnitee, including any action, suit or proceeding (or any part thereof) initiated by such Indemnitee against the Company or its directors, officers, employees or other Indemnitees in their capacity as such, but
excluding: (i) a judicial proceeding or arbitration pursuant to Section 10 to enforce rights under this Agreement; (ii) any action, suit or proceeding (or any part thereof) that the Board authorized prior to its initiation; or
(iii) any action, suit or proceeding (or any part thereof) with respect to which the Board elects to provide indemnification or payment of expenses, in its sole discretion, pursuant to the powers vested in it under applicable law; or

  
 2 

 (e) with respect to any action, suit or proceeding brought by or on behalf
of the Company against Indemnitee that is authorized by the Board, except as provided in Sections 4, 5 and 6 below. 
 3.
Action or Proceedings Other than an Action by or in the Right of the Company. Except as limited by Section 2 above, Indemnitee shall be entitled to the indemnification rights provided in this Section if Indemnitee was or is a party or is
threatened to be made a party to, or otherwise was involved or becomes or may become involved in, any Proceeding (other than an action by or in the right of the Company) by reason of the fact that Indemnitee is or was a director, officer, employee
or agent of the Company, or is or was a director or officer serving at the request of the Company as a director, officer, employee or agent or fiduciary of any other entity (including, but not limited to, another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise); or by reason of anything done or not done by Indemnitee in any such capacity. Pursuant to this Section, Indemnitee shall be indemnified against all costs, judgments, penalties, fines, ERISA
excise taxes, liabilities, amounts paid in settlement by or on behalf of Indemnitee, and Expenses actually and reasonably incurred by Indemnitee in connection with such Proceeding, if Indemnitee acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe his or her conduct was unlawful. 

4. Indemnity in Proceedings by or in the Name of the Company. Except as limited by Section 2 above, Indemnitee shall be
entitled to the indemnification rights provided in this Section if Indemnitee was or is a party or is threatened to be made a party to, or otherwise was involved or becomes or may become involved in, any Proceeding brought by or in the name of the
Company to procure a judgment in its favor by reason of the fact that Indemnitee is or was a director, officer, employee or agent of the Company, or is or was a director or officer serving at the request of the Company as a director, officer,
employee or agent or fiduciary of any other entity (including, but not limited to, another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise); or by reason of anything done or not done by Indemnitee in any
such capacity. Pursuant to this Section, Indemnitee shall be indemnified against all costs, judgments, penalties, fines, ERISA excise taxes, liabilities, amounts paid in settlement by or on behalf of Indemnitee, and Expenses actually and reasonably
incurred by Indemnitee in connection with such Proceeding if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, that no such
indemnification shall be made in respect of any claim, issue, or matter as to which Delaware law expressly prohibits such indemnification by reason of any adjudication of liability of Indemnitee to the Company, unless and only to the extent that the
Court of Chancery of the State of Delaware or the court in which such Proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is entitled to
indemnification for such costs, judgments, penalties, fines, ERISA excise taxes, liabilities, amounts paid in settlement by or on behalf of Indemnitee, and Expenses as such court shall deem proper.

 5. Indemnification for Costs, Charges and Expenses of Successful Party.
Notwithstanding the limitations of Sections 2(c), 2(e), 3 and 4 above, to the extent that Indemnitee has been successful, on the merits or otherwise, in whole or in part, in defense of any Proceeding (including an action, suit or proceeding brought
by or in the right of the Company) or in defense of any claim, issue or matter therein, including, without limitation, the dismissal of any action without prejudice, or if it is ultimately determined, by final judicial decision of a court of
competent jurisdiction from which there is no further right to appeal, that Indemnitee is otherwise entitled to be indemnified against Expenses, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred in connection
therewith. For purposes of this Agreement and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal or withdrawal, with or without prejudice, shall be deemed to be a successful result with respect to
Indemnitee as to such claim, issue or matter. Without limiting the foregoing, if any Proceeding or any claim, issue or matter therein is disposed of or withdrawn, on the merits or otherwise (including a disposition without prejudice), without
(i) the disposition being adverse to the Indemnitee, (ii) an adjudication that the Indemnitee was liable to the Company, (iii) a plea of guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the Indemnitee
did not act in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or (v) with respect to any criminal proceeding, an adjudication that the Indemnitee had reasonable cause
to believe such Indemnitee’s conduct was unlawful, the Indemnitee shall be considered for the purposes hereof to have been wholly successful with respect thereto. 
 6. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of the costs, judgments, penalties, fines, ERISA
excise taxes, liabilities, amounts paid in settlement by or on behalf of Indemnitee, or Expenses actually and reasonably incurred in connection with any Proceeding (including a Proceeding brought by or in the right of the Company) or in connection
with any judicial proceeding or arbitration pursuant to Section 10 to enforce rights under this Agreement, but not, however, for all of the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion of such costs,
judgments, penalties, fines, ERISA excise taxes, liabilities, amounts paid in settlement by or on behalf of Indemnitee, and Expenses actually and reasonably incurred by Indemnitee to which Indemnitee is entitled. 

7. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the maximum extent
permitted by applicable law, Indemnitee shall be entitled to indemnification against all Expenses actually and reasonably incurred or suffered by Indemnitee or on Indemnitee’s behalf if Indemnitee appears as a witness or otherwise incurs legal
expenses as a result of or related to Indemnitee’s service as a director, officer, employee or agent of the Company (or Indemnitee’s service, at the request of the Company, as a director, officer, employee or agent or fiduciary of any
other entity, including, but not limited to, another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise), in any actual, threatened, pending or completed action, suit, arbitration, alternate dispute resolution
mechanism, investigation, inquiry, judicial, administrative or legislative hearing, or any other actual, threatened, pending or completed proceeding or matter to which, at the time such expenses were incurred, Indemnitee neither is, nor is
threatened to be made, a party.

 8. Determination of Entitlement to Indemnification. Upon written request by
Indemnitee for indemnification pursuant to Section 3, 4, 5, 6 or 7 the entitlement of Indemnitee to indemnification, to the extent not provided pursuant to the terms of this Agreement, shall be determined by the following person or
persons who shall be empowered to make such determination: (a) the Board by a majority vote of Disinterested Directors, whether or not such majority constitutes a quorum; (b) a committee of Disinterested Directors designated by a majority
vote of such directors, whether or not such majority constitutes a quorum; (c) if there are no Disinterested Directors, or if the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall
be delivered to Indemnitee; (d) the stockholders of the Company; or (e) in the event that a Change in Control has occurred, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee. Such
Independent Counsel shall be selected by the Board, and approved by Indemnitee, except that in the event that a Change in Control has occurred, Independent Counsel shall be selected by Indemnitee. Upon failure of the Board so to select such
Independent Counsel or upon failure of Indemnitee so to approve (or so to select, in the event a Change in Control has occurred), such Independent Counsel shall be selected upon application to a court of competent jurisdiction. Such determination of
entitlement to indemnification shall be made not later than 30 calendar days after receipt by the Company of a written request for indemnification and, unless a contrary determination is made, such indemnification shall be paid in full by the
Company not later than 60 calendar days after receipt by the Company of such request. Such request shall include documentation or information which is necessary for such determination and which is reasonably available to Indemnitee. If the person
making such determination shall determine that Indemnitee is entitled to indemnification as to part (but not all) of the application for indemnification, such person shall reasonably prorate such partial indemnification among the claims, issues or
matters at issue at the time of the determination. 
 9. Presumptions and Effect of Certain Proceedings. The Secretary of
the Company shall, promptly upon receipt of Indemnitee’s written request for indemnification, advise in writing the Board or such other person or persons empowered to make the determination as provided in Section 8 that Indemnitee has made
such request for indemnification. Upon making such request for indemnification, Indemnitee shall be presumed to be entitled to indemnification hereunder and the Company shall have the burden of proof in making any determination contrary to such
presumption. If the person or persons so empowered to make such determination shall have failed to make the requested determination with respect to indemnification within 30 calendar days after receipt by the Company of such request, a requisite
determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be absolutely entitled to such indemnification, absent actual fraud in the request for indemnification. The termination of any Proceeding
described in Sections 3 or 4 by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself: (a) create a presumption that Indemnitee did not act in good faith and in a
manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful; or
(b) otherwise adversely affect the rights of Indemnitee to indemnification except as may be provided herein. 
 10.
Remedies of Indemnitee in Cases of Determination not to Indemnify or to Pay Expenses. In the event that a determination is made that Indemnitee is not entitled to 

  
 5 

 
indemnification hereunder or if payment has not been timely made following a determination of entitlement to indemnification pursuant to Sections 8 and 9, or if Expenses are not timely
paid pursuant to Section 15, Indemnitee shall be entitled to final adjudication in a court of competent jurisdiction in the State of Delaware of entitlement to such indemnification or payment. Alternatively, Indemnitee at Indemnitee’s
option may seek an award in an arbitration to be conducted by a single arbitrator in the State of Delaware pursuant to the rules of the American Arbitration Association, such award to be made within 60 calendar days following the filing of the
demand for arbitration. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration or any other claim. The determination in any such judicial proceeding or arbitration shall be made de novo and
Indemnitee shall not be prejudiced by reason of a determination (if so made) pursuant to Sections 8 or 9 that Indemnitee is not entitled to indemnification. Neither the failure of the Company (including the Disinterested Directors, a
committee of Disinterested Directors, Independent Counsel, or its stockholders) to have made a determination prior to the commencement of such judicial proceeding or arbitration that indemnification of Indemnitee is proper in the circumstances
because the Indemnitee has met the standard of conduct described above, nor an actual determination by the Company (including the Disinterested Directors, a committee of Disinterested Directors, Independent Counsel, or its stockholders) that
Indemnitee has not met the standard of conduct described above, shall create a presumption that Indemnitee has not met the standard of conduct described above, or, in the case of a judicial proceeding or arbitration brought by Indemnitee, be a
defense to such proceeding or arbitration. In any judicial proceeding or arbitration brought by Indemnitee to enforce a right to indemnification or payment of Expenses hereunder, or brought by the Company to recover a payment of Expenses pursuant to
the terms of an undertaking, the burden of proving that Indemnitee is not entitled to indemnification, or to such payment of expenses, under this Section 10 or otherwise shall be on the Company. If a determination is made or deemed to have been
made pursuant to the terms of Section 8 or 9 that Indemnitee is entitled to indemnification, the Company shall be bound by such determination and is precluded from asserting that such determination has not been made or that the procedure
by which such determination was made is not valid, binding and enforceable. The Company further agrees to stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement and is precluded
from making any assertions to the contrary. If the court or arbitrator shall determine that Indemnitee is entitled to any indemnification or payment of Expenses hereunder, the Company shall pay all Expenses actually and reasonably incurred by
Indemnitee in connection with such adjudication or award in arbitration (including, but not limited to, any appellate proceedings) to the fullest extent authorized by law, and in any judicial proceeding or arbitration brought by the Company to
recover a payment of Expenses pursuant to the terms of an undertaking, the Company shall pay all Expenses actually and reasonably incurred by the Indemnitee in connection with such proceeding or arbitration to the extent the Indemnitee has been
successful, on the merits or otherwise, in whole or in part, in defense of such proceeding or arbitration, to the fullest extent authorized by law. 
 11. Other Rights. Indemnification and payment of Expenses provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may now or in the future be entitled under
any provision of the bylaws or other organizational documents of the Company, vote of stockholders or Disinterested Directors, provision of law, agreement or otherwise. 

  
 6 

 12. Expenses to Enforce Agreement. In the event that Indemnitee is subject to or
intervenes in any action, suit or proceeding in which the validity or enforceability of this Agreement is at issue or seeks an adjudication or award in arbitration to enforce Indemnitee’s rights under, or to recover damages for breach of, this
Agreement, Indemnitee, if Indemnitee prevails in whole or in part in such action, suit or proceeding shall be entitled to recover from the Company and shall be indemnified by the Company against any Expenses actually and reasonably incurred by
Indemnitee. 
 13. Continuation of Indemnity. All agreements and obligations of the Company contained herein shall
continue during the period Indemnitee is a director, officer, employee or agent of the Company, or is a director or officer serving at the request of the Company as a director, officer, employee or agent or fiduciary of any other entity (including,
but not limited to, another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise) and shall also continue after the period of such service with respect to any possible claims based on the fact that Indemnitee was
or had been a director, officer, employee or agent of the Company or was or had been a director or officer serving at the request of the Company as a director, officer, employee or agent or fiduciary of any other entity (including, but not limited
to, another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise). This Agreement shall be binding upon all successors and assigns of the Company (including any transferee of all or substantially all of its
assets and any successor by merger or operation of law) and shall inure to the benefit of the heirs, executors and administrators of Indemnitee. 
 14. Notification and Defense of Claim. Promptly after receipt by Indemnitee of notice of any Proceeding, Indemnitee will, if a request for indemnification or payment of Expenses in respect thereof
is to be made against the Company under this Agreement, notify the Company in writing of the commencement thereof; but the omission so to notify the Company will not relieve the Company from any liability that it may have to Indemnitee.
Notwithstanding any other provision of this Agreement, with respect to any such Proceeding of which Indemnitee notifies the Company: 
 (a) The Company shall be entitled to participate therein at its own expense; and 
 (b) Except as otherwise provided in this Section 14(b), to the extent that it may wish, the Company, jointly with any other indemnifying party similarly notified, shall be entitled to assume the
defense thereof, with counsel satisfactory to Indemnitee. After notice from the Company to Indemnitee of its election so to assume the defense thereof, the Company shall not be liable to Indemnitee under this Agreement for any expenses of counsel
subsequently incurred by Indemnitee in connection with the defense thereof except as otherwise provided below. Indemnitee shall have the right to employ Indemnitee’s own counsel in such Proceeding, but the fees and expenses of such counsel
incurred after notice from the Company of its assumption of the defense thereof shall be at the expense of Indemnitee unless (i) the employment of counsel by Indemnitee has been authorized by the Company, (ii) Indemnitee shall have
reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of the defense of such Proceeding or (iii) the Company shall not within 60 calendar days of receipt of notice from Indemnitee in
fact have employed counsel to assume the defense 

  
 7 

 
of the Proceeding, in each of which cases the fees and expenses of Indemnitee’s counsel shall be at the expense of the Company. The Company shall not be entitled to assume the defense of any
Proceeding brought by or on behalf of the Company or as to which Indemnitee shall have made the conclusion provided for in (ii) above; and 
 (c) If the Company has assumed the defense of a Proceeding, the Company shall not be liable to indemnify Indemnitee under this Agreement for any amounts paid in settlement of any Proceeding effected
without the Company’s written consent. The Company shall not settle any Proceeding in any manner that would involve an admission of guilt or wrongful conduct by Indemnitee, or impose any penalty, prohibition, restriction or limitation on, or
disclosure obligation with respect to, Indemnitee without Indemnitee’s prior written consent. Neither the Company nor Indemnitee will unreasonably withhold such party’s consent to any proposed settlement. 

15. Payment of Expenses. 
 (a) All Expenses incurred by Indemnitee in defending any Proceeding shall be paid by the Company in advance of the final disposition of such Proceeding at the request of Indemnitee, each such
payment to be made within 20 calendar days after the receipt by the Company of a written statement or statements from Indemnitee requesting such payment or payments from time to time. Such statement or statements shall (i) reasonably evidence
the expenses and costs incurred by Indemnitee in connection therewith; provided, however, that Indemnitee shall not be required to provide any billing detail or other information to the extent that
disclosure of such detail or information would jeopardize any attorney-client or other applicable privilege, as determined by Indemnitee in his or her reasonable discretion; and (ii) include or be accompanied by an undertaking, in substantially
the form attached as Exhibit 1, by or on behalf of Indemnitee to reimburse any such Expenses if it is ultimately determined, by final judicial decision of a court of competent jurisdiction from which there is no further right to appeal, that
Indemnitee is not entitled to be indemnified against such Expenses by the Company as provided by this Agreement or otherwise. 
 (b) Advances shall be made without making or requiring any determination or evidence as to Indemnitee’s ability to repay the Expenses and without regard to the Indemnitee’s ultimate entitlement
to indemnification under the other provisions of this Agreement or otherwise. Advances shall be unsecured and interest-free. Advances shall include any and all Expenses actually and reasonably incurred by Indemnitee in pursuing a judicial proceeding
or arbitration to enforce rights under this Agreement, including Expenses incurred preparing and forwarding information to the Company to support amounts requested; provided, however, that such Expenses shall be subject to reimbursement in
accordance with the undertaking described in Section 15(a) above. An Indemnitee shall qualify for advances solely upon the execution and delivery to the Company of the undertaking described in Section 15(a). 

(c) Notwithstanding anything in this Agreement to the contrary, the Company shall not be required to advance any expenses to an
Indemnitee in the event and to the extent that such Indemnitee has entered a plea of guilty in the applicable criminal Proceeding. 

  
 8 

 16. Contribution. To the fullest extent permissible under applicable law, if
the indemnification provided for in this Agreement is unavailable to an Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying the Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines
(including any excise taxes), penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and
reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding and/or
(ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 
 17. Separability; Prior Indemnification Agreements. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever (a) the
validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, all portions of any paragraphs of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are
not by themselves invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby, and (b) to the fullest extent possible, the provisions of this Agreement (including, without limitation, all portions of any paragraph of
this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall be construed so as to give effect to the intent of the parties that the Company provide
protection to Indemnitee to the fullest enforceable extent. This Agreement shall supersede and replace any prior indemnification agreements entered into by and between the Company and Indemnitee and any such prior agreements shall be terminated upon
execution of this Agreement. 
 18. Headings; References; Pronouns. The headings of the sections of this Agreement are
inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof. References herein to section numbers are to sections of this Agreement. All pronouns and any variations thereof shall
be deemed to refer to the masculine, feminine, neuter, singular or plural as appropriate. 
 20. Definitions. For
purposes of this Agreement: 
 (a) “Board” means the Board of Directors of the Company. 

(b) “Change in Control” means a situation where the individuals who, as of the Effective Date, constitute the Board (the
“Incumbent Board”) cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the Effective Date whose election, or nomination for election by the
stockholders of the Company, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any
such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf
of a person other than the Board. 

  
 9 

 (c) “Disinterested Director” means a director of the Company who is not or
was not a party to the Proceeding in respect of which indemnification is being sought by Indemnitee. 
 (d)
“Expenses” includes, without limitation, expenses incurred in connection with the defense or settlement of any action, suit, arbitration, alternative dispute resolution mechanism, investigation, inquiry, judicial, administrative or
legislative hearing, or any other actual, threatened, pending or completed proceeding, including any and all appeals, whether brought by or in the right of the Company or otherwise and whether of a civil, criminal, administrative, legislative,
investigative or other nature, attorneys’ fees, witness fees and expenses, fees and expenses of accountants and other advisors, retainers and disbursements and advances thereon, the premium, security for, and other costs relating to any bond
(including cost bonds, appraisal bonds or their equivalents), and any expenses of establishing a right to indemnification or payment of expenses under Sections 8, 10, 12 and 15 above but shall not include the amount of judgments,

right to indemnification or payment of Expenses under this Agreement.

Securities Exchange Act of 1934, or their respective state counterparts or any rule or regulation promulgated thereunder, in which Indemnitee may be or may have been involved as a party or otherwise, by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company, or is or was a director or officer serving, at the request of the Company, as a director, officer, employee or agent or fiduciary of any other entity, including, but not limited to, another
corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, or by reason of anything done or not done by Indemnitee in any such capacity, whether or not Indemnitee is serving in such capacity at the time any liability

 21. Other Provisions. 

(a) This Agreement shall be interpreted and enforced in accordance with the laws of Delaware. 

(b) This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all
of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced as evidence of the existence of this Agreement. 

(c) This agreement shall not be deemed an employment contract between the Company and any Indemnitee who is an officer of the Company,
and, if Indemnitee is an officer of the Company, Indemnitee specifically acknowledges that Indemnitee may be discharged at any time for any reason, with or without cause, and with or without severance compensation, except as may be otherwise
provided by law or in a separate written contract between Indemnitee and the Company. 
 (d) Upon a payment to Indemnitee under
this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of Indemnitee to recover against any person for such liability, and Indemnitee shall execute all documents and instruments required and shall take
such other actions as may be necessary to secure such rights, including the execution of such documents as may be necessary for the Company to bring suit to enforce such rights. 

(e) No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both parties hereto. No
waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. Any waiver of any of the provisions of this
Agreement must be in writing and executed by the party against whom such waiver is to be effective.

 My commission expires:Employment Agreement, dated as of June 2, 2011

 Exhibit 10.8 
 EMPLOYMENT AGREEMENT 
 This Employment Agreement (the
“Agreement”), dated as of June 2, 2011 is entered into by and among Lyondell Chemical Company, a Delaware corporation (the Company”) and Tim Roberts (the “Executive”). 

W I T N E S S E T H: 

WHEREAS, the Company desires to employ Executive and Executive desires to accept such employment. 

NOW, THEREFORE, in consideration of the mutual covenants set forth in this Agreement, it is hereby agreed as follows: 

1. Employment. The Company agrees to employ Executive, and Executive agrees to be employed by the Company, subject to the terms and
conditions of this Agreement. The Executive’s employment by the Company pursuant to this Agreement shall commence on May 16, 2011 (or such earlier date agreed to by the parties hereto) (the “Effective Date”). Notwithstanding
anything herein to the contrary, Executive shall be an at-will employee of the Company, which means either the Company or Executive may terminate Executive’s employment with the Company at any time for any reason, with or without Cause (as
defined below). 
 2. Position, Duties and Location. While employed by the Company, 

(a) Position and Duties. Executive shall serve as Senior Vice President, Olefins & Polyolefins—Americas of
LyondellBasell Industries N.V. (“Parent Company”) and its Subsidiaries (the “LBI Group”), with the duties and responsibilities customarily assigned to such positions (including, without limitation, responsibility for the
oversight and management of the supply and marketing of olefins, polyolefins and their co-products and derivatives for the LBI Group) and such other customary duties as may reasonably be assigned to Executive from time to time by the Chief Executive
Officer of the LBI Group (the “Chief Executive Officer”), consistent with such positions. Executive shall report directly to the Chief Executive Officer. Executive shall be a member of the most senior management team of the LBI Group.

 (b) Attention and Time. Executive shall devote substantially all his business attention and time to his duties
hereunder and shall use his reasonable best efforts to carry out such duties faithfully and efficiently. 
 (c) Location.
Executive’s principal place of employment shall be located in Houston, Texas; provided that Executive shall travel and shall render services at other locations, both as may reasonably be required by his duties hereunder. 

 3. Compensation. 

(a) Signing Bonus. Executive shall receive $1,065,562 within five (5) business days of the Effective Date (the “Signing
Bonus”). If Executive voluntarily terminates his employment without Good Reason (as defined below) prior to the first year anniversary of the Effective Date, Executive shall be obligated to repay to the Company the Signing Bonus and the Company
may offset the repayment of any Accrued Amounts (as defined below) against such repayment obligation. 
 (b) Base Salary.
While employed by the Company, Executive shall receive a base salary (the “Base Salary”) at an annual rate of not less than $450,000. Base Salary shall be paid at such times and in such manner as the Company customarily pays the base
salaries of its employees. In the event that Executive’s Base Salary is increased by the Board (as defined below) in its discretion, such increased amount shall thereafter constitute the Base Salary. 

(c) Annual Bonus. Executive shall be paid an annual cash bonus calculated in accordance with the Company’s short-term
incentive plan as in effect from time to time (the “Annual Bonus”) based on the attainment of performance targets established by the Board. The Annual Bonus shall be targeted at not less than 75% of Base Salary (as in effect at the
beginning of each such year). The actual amount of the Annual Bonus (if any) for any year shall depend on the level of achievement of the applicable performance criteria established with respect to such bonus by the Board in its discretion. The
Annual Bonus shall be payable at such time as bonuses are paid to other senior executive officers of the Company and the payment terms shall comply with or be exempt from the requirements of Section 409A. 

(d) Incentive Awards. With respect to each year of employment with the Company, Executive shall be eligible to receive a long-term
incentive award in the form of an equity award with respect to the Parent Company’s common stock (the “Common Stock”), which award may consist of restricted stock, restricted stock units, stock options, stock appreciation rights or
other types of equity-based awards consistent with the Company’s long-term incentive program as in effect from time to time (the “LTI Plan), or any combination thereof, as determined by the Board in its discretion, consistent with the
Company’s LTI Plan (the “LTI Award”) and/or a mid-term incentive award (“MTI Award”) with a targeted total collective value of not less than 150% of the aggregate amount of Base Salary earned by Executive during such
calendar year, as determined by the Board in its discretion. The terms and conditions of the LTI Awards (including, without limitation, the form of awards, the purchase price (if any), vesting conditions, exercise rights, payment terms, termination
provisions, transfer restrictions and repurchase rights) shall be determined in a manner consistent with the LTI Plan. The terms of an MTI Award shall be determined consistent with the Company’s mid-term incentive program as in effect from time
to time (the “MTI Plan”). The payment terms under the MTI Plan and LTI Plan shall comply with or be exempt from the requirements of Section 409A. 
 (e) Employee Benefits. While employed by the Company, the Company shall provide, and Executive shall be entitled to participate in or receive benefits under any pension plan, profit sharing plan,
stock option plan, stock purchase plan or arrangement, health, disability and accident plan or any other employee benefit plan or arrangement made available now or in 

 
the future to senior executives of the Company; provided that Executive complies with the conditions attendant with coverage under such plans or arrangements. Except as expressly provided in this
Agreement (including, without limitation, Section 3(d) hereof), nothing contained herein shall be construed to prevent the Company from modifying or terminating any plan or arrangement in existence on the date hereof, provided that no such
modification or termination adversely affects any award or other entitlement previously granted to Executive. Without limiting the generality of the foregoing, Executive shall be entitled to no less than four (4) weeks of paid vacation per
calendar year (pro-rated for the portion of the 2011 calendar year Executive is employed by the Company). 
 (f) Business
Expenses. While employed by the Company, the Company shall promptly pay or, if such expenses are paid directly by Executive, Executive shall be entitled to receive prompt reimbursement, for all reasonable expenses that Executive incurs during
his employment with the Company in carrying out Executive’s duties under this Agreement, including, without limitation, those incurred in connection with business related travel or entertainment, upon presentation of expense statements and
customary supporting documentation. 
 (g) Moving Expenses. The Company shall reimburse relocation expenses incurred by
Executive in accordance with the Company’s U.S. Relocation – New Hire Homeowner Plan (“Relocation Policy”), which Relocation Policy shall be applied without reference to the requirement that the employee’s commute must
increase by 50 miles. 
 4. Termination of Employment. 

(a) Termination of Employment Without Cause or for Good Reason. The Company may terminate Executive’s employment without
Cause and Executive may terminate his employment for Good Reason, in each case upon thirty (30) days prior written notice. In the event that, within five (5) years of the Effective Date, the Company terminates Executive’s employment
without Cause (other than due to Executive’s disability) or Executive terminates his employment for Good Reason, Executive shall be entitled to the following in lieu of any payments or benefits under any severance program or policy of the
Company: 
 (i) any Accrued Amounts; and 

(ii) subject to Executive’s execution of a general release of claims in favor of the Company and the LBI Group and
any Affiliate and their respective current and former officers and directors in form and substance acceptable to the Company not more than twenty (20) days after the date of termination, a lump sum cash payment in an amount equal to
Executive’s then current annual Base Salary plus an amount equal to Executive’s target Annual Bonus for the year of termination, payable within thirty (30) days of termination. 

(b) Other Termination Events. In the event that (i) the Company terminates Executive’s employment for Cause,
(ii) Executive terminates his employment without Good Reason or (iii) Executive’s employment terminates due to his death or disability or for any other 

 
reason not covered by Section 4(a) above, Executive (or, in the case of Executive’s death, Executive’s estate and/or beneficiaries) shall be entitled to any Accrued Amounts, but
shall have no further right or entitlement under this Agreement to any other payments or benefits. 
 (c) Definitions.
For purposes of this Agreement, the following definitions shall apply: 
 (i) “Accrued Amounts” shall
mean (A) unpaid Base Salary through the date of termination; (B) any earned but unpaid bonus for the prior fiscal year; (C) any expenses owed to Executive and (D) any benefits payable or provided in accordance with the terms of
any employee benefit plan (including the MTI Plan and the LTI Plan, but specifically excluding any plan or program providing severance or termination pay) in which Executive participates. 

(ii) “Affiliate” of a person or other entity shall mean: a person or other entity that directly or indirectly
controls, is controlled by, or is under common control with the person or other entity specified. 
 (iii)
“Board” shall mean the Supervisory Board of the Parent Company (or a duly authorized committee thereof). 
 (iv) “Cause” shall mean: (A) Executive’s continuing failure (except where due to physical or mental incapacity) to substantially perform his duties hereunder; (B) Executive’s
willful malfeasance or gross neglect in the performance of his duties; (C) Executive’s conviction of, or plea of guilty or nolo contendere to, a felony or a misdemeanor involving moral turpitude; (D) the commission by Executive
of an act of fraud or embezzlement against the Company or any Affiliate; or (E) Executive’s willful breach of any material provision of this Agreement (as determined in good faith by the Board) which is not remedied within fifteen
(15) after written notice is received from the Company specifying such breach. 
 (v) “Good
Reason” shall mean the occurrence, without Executive’s express written consent, of: (A) an adverse change in Executive’s employment’s title or change in Executive’s duty to report directly to the Chief Executive
Officer; (B) a material diminution in Executive’s employment duties, responsibilities or authority, or the assignment to Executive of duties that are materially inconsistent with his position; (C) any material reduction in Base
Salary, or Annual Bonus target as set forth in Section 3(c); or (D) any willful breach by the Company of any material provision of this Agreement (including but not limited to any breach of its obligations under Section 3 hereof)
which is not cured within fifteen (15) days after written notice is received from Executive specifying such breach. 
 (vi) “Subsidiary” of the Parent Company shall mean: any corporation, limited liability company, joint venture or partnership, in which the Parent Company (or its direct or indirect Subsidiary)
holds more than 50 percent of the equity interest. 

 5. Confidentiality of Trade Secrets and Business Information. Executive agrees that
Executive shall not, at any time during Executive’s employment with the Company or thereafter, disclose or use any trade secret, proprietary or confidential information of the Company or any Subsidiary of the Parent Company (collectively,
“Confidential Information”), obtained by him during the course of such employment, except for (i) disclosures and uses required in the course of such employment or with the written permission of the Company, (ii) disclosures with
respect to any litigation, arbitration or mediation involving this Agreement, including but not limited to, the enforcement of Executive’s rights under this Agreement, or (iii) as may be required by law or by any court, arbitrator,
mediator or administrative or legislative body (including any committee thereof) with apparent jurisdiction to order such disclosure; provided that, if, in any circumstance described in clause (iii), Executive receives notice that any third party
shall seek to compel him by process of law to disclose any Confidential Information, Executive shall promptly notify the Company and provide reasonable cooperation to the Company (at the Company’s sole expense) in seeking a protective order
against such disclosure. Notwithstanding the foregoing, “Confidential Information” shall not include information that is or becomes publicly known outside the Parent Company or the Company or any of their subsidiaries other than due to a
breach of Executive’s obligations under this paragraph. 
 6. Return of Information. Executive agrees that at the
time of any termination of Executive’s employment with the Company, whether at the instance of Executive or the Company, and regardless of the reasons therefore, Executive shall deliver to the Company (at the Company’s expense), any and
all notes, files, memoranda, papers and, in general, any and all physical (including electronic) matter containing Confidential Information (other than as he properly is retaining in connection with an action or other proceeding as noted in clause
(ii) or (iii) of Section 5) which are in Executive’s possession, except as otherwise consented in writing by the Company at the time of such termination. The foregoing shall not prevent Executive from retaining copies of personal
diaries, personal notes, personal address books, personal calendars, and any other personal information (including, without limitation, information relating to Executive’s compensation), but only to the extent such copies do not contain any
Confidential Information other than that which relates directly to Executive, including his compensation. 
 7.
Noninterference. In consideration for the compensation payable to Executive under this Agreement, Executive agrees that Executive shall not, during Executive’s employment with the Company (other than in carrying out his duties hereunder)
and for a period of one (1) year after any termination of employment: (i) directly or indirectly recruit, solicit or induce, any employee, consultant or independent contractor of the Parent Company or any Subsidiary, to terminate, alter or
modify such person’s employment or other relationship with the Parent Company or any Subsidiary, or (ii) directly or indirectly solicit any then current customer or business partner of the Parent Company or any Subsidiary to terminate,
alter or modify its relationship with the Parent Company or the Subsidiary or to interfere with the Parent Company’s or any Subsidiary’s relationships with any of its customers or business partners on behalf of any enterprise that is a
competitor with the Parent Company or a Subsidiary. 

 8. Enforcement. Executive acknowledges and agrees that: (i) the purpose of the
covenants set forth in Sections 5 through 7 above (the “Restrictive Covenants”) is to protect the goodwill, trade secrets and other confidential information of the Parent Company and its Subsidiaries; (ii) because of the nature of the
business in which the Parent Company is engaged and because of the nature of the Confidential Information to which Executive has access, it would be impractical and excessively difficult to determine the actual damages of the Parent Company in the
event Executive breached any such covenants; and (iii) remedies at law (such as monetary damages) for any breach of Executive’s obligations under the Restrictive Covenants would be inadequate. Executive therefore agrees and consents that
if Executive commits any breach of a Restrictive Covenant, the Company shall have the right (in addition to, and not in lieu of, any other right or remedy that may be available to it) to temporary and permanent injunctive relief from a court of
competent jurisdiction, without posting any bond or other security and without the necessity of proof of actual damage. If any portion of the Restrictive Covenants is hereafter determined to be invalid or unenforceable in any respect, such
determination shall not affect the remainder thereof, which shall be given the maximum effect possible and shall be fully enforced, without regard to the invalid portions. In particular, without limiting the generality of the foregoing, if the
covenants set forth in Section 7 are found by a court or an arbitrator to be unreasonable, Executive and the Company agree that the maximum period, scope or geographical area that is found to be reasonable shall be substituted for the stated
period, scope or area, and that the court or arbitrator shall revise the restrictions contained herein to cover the maximum period, scope and area permitted by law. If any of the Restrictive Covenants are determined to be wholly or partially
unenforceable in any jurisdiction, such determination shall not be a bar to or in any way diminish the Company’s right to enforce any such covenant in any other jurisdiction. 

9. Indemnification. The Company shall indemnify Executive against any and all losses, liabilities, damages, expenses (including
reasonable attorneys’ fees) judgments, fines and amounts paid in settlement incurred by Executive in connection with any claim, action, suit or proceeding (whether civil, criminal, administrative or investigative), including any action by or in
the right of the Company, by reason of any act or omission to act in connection with the performance of his duties hereunder or otherwise arising out of his employment by the Company, on term and conditions no less favorable to Executive than any
other officer or director of the Company, to the extent permitted by applicable law. 
 10. Arbitration. In the event
that any dispute arises between the Company and Executive regarding or relating to this Agreement and/or any aspect of Executive’s employment relationship with the Company, the parties consent to resolve such dispute through mandatory
arbitration in Houston, Texas (or such other location as shall be mutually agreed between the parties) administered by JAMS pursuant to its Employment Arbitration Rules & Procedures and subject to JAMS Policy on Employment Arbitration
Minimum Standards of Procedural Fairness. The parties hereby consent to the entry of judgment upon award rendered by the arbitrator in any court of competent jurisdiction. Notwithstanding the foregoing, however, should adequate grounds exist for
seeking immediate injunctive or immediate equitable relief, any party may seek and obtain such relief. The parties hereby consent to the exclusive jurisdiction of the state and Federal courts of or in the State of Texas for purposes of seeking such
injunctive or equitable relief as set forth above. 

 11. Executive and Company Representations. 

(a) Executive acknowledges that before signing this Agreement, Executive was given the opportunity to read it, evaluate it and discuss it
with Executive’s personal advisors. Executive further acknowledges that the Company has not provided Executive with any legal advice regarding this Agreement. 
 (b) Executive represents and warrants to the Company that the execution and delivery of this Agreement and the fulfillment of the terms hereof (i) shall not constitute a default under, or conflict
with, any agreement or other instrument to which he is a party or by which he is bound and (ii) as to his execution and delivery of this Agreement do not require the consent of any other person. 

(c) The Company represents and warrants to Executive that (i) the execution, delivery and performance of this Agreement by the
Company has been fully and validly authorized by all necessary corporate action, (ii) the person signing this Agreement on behalf of the Company is duly authorized to do so, (iii) the execution, delivery and performance of this Agreement
does not violate any applicable law, regulation, order, judgment or decree or any agreement, plan or corporate governance document to which the Company or the Parent Company is a party or by which it is bound and (iv) upon execution and
delivery of this Agreement by the parties, it shall be a valid and binding obligation of the Company enforceable against it in accordance with its terms, except to the extent that enforceability may be limited by applicable bankruptcy, insolvency or
similar laws affecting the enforcement of creditors’ rights generally. 
 12. Notices. All notices and other
communications required or permitted hereunder shall be in writing and shall be deemed given when delivered (i) personally, (ii) by registered or certified mail, postage prepaid with return receipt requested, (iii) by facsimile with
evidence of completed transmission, or (iv) delivered by overnight courier to the party concerned at the address indicated below or to such changed address as such party may subsequently give such notice of:

If to Executive: 
 Tim Roberts 

 13. Assignment and Successors. This Agreement is personal in its nature and none of
the parties hereto shall, without the consent of the others, assign or transfer this Agreement or any rights or obligations hereunder; provided, however, that in the event of a merger, consolidation, or transfer or sale of all or substantially all
of the assets of the Company with or to any other individual(s) or entity, this Agreement shall, subject to the provisions hereof, be binding upon and inure to the benefit of such successor and such successor shall discharge and perform all the
promises, covenants, duties, and obligations of the Company hereunder, and such transferee or successor shall be required to assume such obligations by contract (unless such assumption occurs by operation of law). Anything herein to the contrary
notwithstanding, Executive shall be entitled to select (and change, to the extent permitted under any applicable law) a beneficiary or beneficiaries to receive any compensation or benefit payable hereunder following Executive’s death or
judicially determined incompetence by giving the Company written notice thereof. In the event of Executive’s death or a judicial determination of his incompetence, reference in this Agreement to Executive shall be deemed, where appropriate, to
refer to his beneficiary, estate or other legal representative. 
 14. Governing Law; Amendment. This Agreement shall be
governed by and construed in accordance with the laws of the State of Texas, without reference to principles of conflict of laws. This Agreement may not be amended or modified except by a written agreement executed by Executive and the Company or
their respective successors and legal representatives. 
 15. Severability. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement. If any provision of this Agreement shall be held invalid or unenforceable in part, the remaining portion of such provision,
together with all other provisions of this Agreement, shall remain valid and enforceable and continue in full force and effect to the fullest extent consistent with law. 
 16. Tax Withholding. Notwithstanding any other provision of this Agreement, the Company may withhold from amounts payable under this Agreement all federal, state, local and foreign taxes that are
required to be withheld by applicable laws or regulations. 
 17. No Waiver. Executive’s or the Company’s
failure to insist upon strict compliance with any provision of, or to assert any right under, this Agreement shall not be deemed to be a waiver of such provision or right or of any other provision of or right under this Agreement. Any provision of
this Agreement may be waived by the parties hereto; provided that any waiver by any person of any provision of this Agreement shall be effective only if in writing and signed by each party and such waiver must specifically refer to this Agreement
and to the terms or provisions being modified or waived. 
 18. Section 409A. This Agreement is intended to satisfy
the requirements of Section 409A with respect to amounts, if any, subject thereto and shall be interpreted and construed and shall be performed by the parties consistent with such intent. To the extent Executive would otherwise be entitled to
any payment under this Agreement, or any plan or 

 
arrangement of the Company or its Affiliates, that constitutes a “deferral of compensation” subject to Section 409A and that if paid during the six (6) months beginning on the
Date of Termination of Executive’s employment would be subject to the Section 409A additional tax because Executive is a “specified employee” (within the meaning of Section 409A and as determined by the Company), the payment
will be paid to Executive on the earlier of the six (6) month anniversary of his Date of Termination or death. To the extent Executive would otherwise be entitled to any benefit (other than a payment) during the six (6) months beginning on
termination of Executive’s employment that would be subject to the Section 409A additional tax, the benefit will be delayed and will begin being provided on the earlier of the first day following the six (6) month anniversary of
Executive’s Date of Termination or death. Any payment or benefit due upon a termination of employment that represents a “deferral of compensation” within the meaning of Section 409A shall be paid or provided only upon a
“separation from service” as defined in Treas. Reg. § 1.409A-1(h). Each payment made under this Agreement shall be deemed to be a separate payment for purposes of Section 409A. Amounts payable under this Agreement shall be deemed
not to be a “deferral of compensation” subject to Section 409A to the extent provided in the exceptions in Treasury Regulation §§ 1.409A-1(b)(4) (“short-term deferrals”) and (b)(9) (“separation pay
plans,” including the exception under subparagraph (iii)) and other applicable provisions of Treasury Regulation § 1.409A-1 through A-6. 
 19. Headings. The Section headings contained in this Agreement are for convenience only and in no manner shall be construed as part of this Agreement. 

20. Entire Agreement. This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof
and, except for matters described in Section 5, 6 or 7 hereof, shall supersede all prior agreements, whether written or oral, with respect thereto. 
 21. Duration of Terms. The respective rights and obligations of the parties hereunder shall survive any termination of Executive’s employment to the extent necessary to give effect to such
rights and obligations. 
 22. Counterparts. This Agreement may be executed simultaneously in two (2) or more
counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. 

 IN WITNESS WHEREOF, Executive and the Company have caused this Agreement to be executed as of the date first
above written.
