 LIMELIGHT NETWORKS, INC. 
 INDU KODUKULA EMPLOYMENT AGREEMENT

 This Employment Agreement (the “Agreement”) is entered into as of October 8, 2012 (the “Signing
Date”), by and between Limelight Networks, Inc. (the “Company”) and Indu Kodukula (“Executive”). 
 1. Duties and
Scope of Employment. 
 (a) Positions and Duties. No later than November 5, 2012, Executive will commence
service as the Company’s Chief Operating Officer (“COO”). Executive will report to the Company’s Chief Executive Officer (the “CEO”). The date on which Executive actually commences such service as the Company’s COO
shall be the “Effective Date.” As of the Effective Date, Executive will render such business and professional services in the performance of his duties, consistent with Executive’s position within the Company, as will reasonably be
assigned to him by the CEO. Without limiting the foregoing, Executive will be responsible for managing all aspects of product management, research and development, CDN, network and storage operations, Software as a Service (SaaS) operations and
customer service and support. Immediate goals will include, inter alia, design and implementation of plans, programs and initiatives that will demonstrably and measurably improve network cost and performance efficiency, assure timely and
efficient design and development of competitive products and services and enhancement of existing products and services, and demonstrably and measurably improve customer support and service. The period Executive is employed by the Company under this
Agreement is referred to herein as the “Employment Term.” In the event that Executive fails to begin full-time employment with the Company by November 5, 2012, this Agreement and any equity awards to be granted pursuant to the terms
hereof shall be null and void upon the date of such failure. Executive will be based in San Francisco, California but will spend such time in the Company’s Tempe, Arizona, Mountain View, California and San Diego, California offices, and will
travel on Company business to such other locations and for such periods, as may be necessary or appropriate to carry out his responsibilities or as may be directed by the Company’s CEO. 

(b) Obligations. During the Employment Term, Executive, except as provided in this Agreement, will devote Executive’s full
business efforts and time to the Company and will use good faith efforts to discharge Executive’s obligations under this Agreement to the best of Executive’s ability and in accordance with each of the Company’s written corporate
guidance and ethics guidelines, conflict of interests policies, code of conduct and other policies and procedures as the Company may adopt from time to time. For the duration of the Employment Term, Executive agrees not to actively engage in any
other employment, occupation, or consulting activity for any direct or indirect remuneration without the prior approval of the CEO (which approval will not be unreasonably withheld); provided, however, that Executive may, without the approval of the
CEO, serve in any capacity with any civic, educational, professional, industry or charitable organization, provided such services do not interfere with Executive’s performance of his obligations to Company, are disclosed in writing to the
Company and are otherwise consistent with the Company’s policies.

Subject to prior approval of the CEO and in appropriate cases (as determined by the Company) approval of the Audit Committee of the Company’s board (which approval will not be unreasonably
withheld) Executive may also serve on the board(s) of for-profit business associations provided such participation does not interfere with Executive’s performance of his obligations to the Company, are disclosed in writing to the Company, are
consistent with the terms of Executive’s employment with the Company (including without limitation the restrictive covenants in the Confidential Information Agreement, as defined in Section 12 below) and are consistent with the
Company’s policies (including without limitation the Company’s Code of Business Conduct). Based upon Executive’s written disclosure regarding Edison Corp. and his role with respect thereto, Executive’s existing participation on
the board of Edison Corp. is approved; provided such approval could change in the future if Executive’s future participation conflicts with any of the provisos in the previous sentence. 

(i) Executive hereby represents, warrants and covenants to the Company that as of the Effective Time, Executive will not be a party to
any contract, understanding, agreement or policy, written or otherwise, that will be breached by Executive’s entering into, or performing services under, this Agreement. Executive further represents that he has disclosed to the Company in
writing all threatened, pending, or actual claims that are unresolved and still outstanding as of the Signing Date, in each case, against Executive of which he is aware, if any, as a result of his employment with any previous employer or his
membership on any boards of directors. 
 (c) Other Entities. Executive agrees to serve if appointed, without additional
compensation, as an officer and director for each of the Company’s subsidiaries, partnerships, joint ventures, limited liability companies and other affiliates, including entities in which the Company has a significant investment as determined
by the Company. As used in this Agreement, the term “affiliates” will mean any entity controlled by, controlling, or under common control of the Company. 
 2. At-Will Employment. Executive and the Company agree that Executive’s employment with the Company constitutes “at-will” employment. Executive and the Company acknowledge that this
employment relationship may be terminated at any time, upon written notice to the other party, with or without good cause or for any or no cause, at the option either of the Company or Executive. However, as described in this Agreement, Executive
may be entitled to severance benefits depending upon the circumstances of Executive’s termination of employment. 
 3. Compensation.

 (a) Base Salary. Commencing with the Effective Date, the Company will pay Executive an annual salary of $350,000 as
compensation for his services (such annual salary, as is then effective, to be referred to herein as “Base Salary”). Executive’s Base Salary will be subject to annual review. The Base Salary will be paid periodically in accordance
with the Company’s normal payroll practices and will be subject to the usual, required withholdings. 
 (b) Annual
Incentive. Executive will be eligible to receive annual cash incentives payable for the achievement of performance goals established by the Board of Directors of the Company (the “Board”) or by the Compensation Committee of the Board
(the “Committee”). 

  
 -2-









 During calendar year 2012 and 2013, Executive’s target annual incentive (“Target Annual
Incentive”) will be $250,000. The Target Annual Incentive for 2012 shall be prorated for the portion of calendar year 2012 during which Executive is an employee of the Company. The actual earned annual cash incentive, if any, payable to
Executive for any performance period will depend upon the extent to which the applicable performance goal(s) specified by the Committee are achieved. Any annual cash incentives earned pursuant to this Section 3(b) will be paid to Executive as
soon as reasonably practicable following the date on which such annual cash incentives are earned, but in no event will be paid later than March 15 of the year following the year in which such annual cash incentives are earned. 

(c) Equity Awards. 
 (i) Subject to Committee approval, on the grant date set by the Committee, the Company will issue to Executive 475,000 Restricted Stock Units (“RSUs”) pursuant the Company’s 2007 Equity
Incentive Plan (the “Plan). The RSUs will be granted under and subject to the terms, definitions and provisions of the Plan. One- quarter (1/4th) of the RSUs will vest on the one year anniversary of the Effective Date, and an additional one-sixteenth
(1/16th) will vest on March 1, 2014 the first
day of each June, September, December and March thereafter, provided Executive continues to be a Service Provider through each such vesting date. 
 (ii) Executive may from time to time be issued stock options, RSUs or other equity awards under the Plan or a successor plan. Such awards together with the equity awards issued pursuant to this Agreement
may be referred to in this Agreement as Equity Awards. 
 (iii) In the event that the Company consummates a Change of Control
transaction, 50% of Executive’s then outstanding unvested Equity Awards will vest immediately. In the event Executive’s employment is terminated in connection with a Change of Control, the balance of Executive’s then outstanding
Equity Awards may vest as provided in Section 7(b) below. 
 4. Employee Benefits. 

(a) Generally. Executive will be eligible to participate in accordance with the terms of all Company employee benefit plans,
policies and arrangements that are applicable to other officers of the Company, as such plans, policies and arrangements may exist from time to time. 
 (b) Vacation. Executive will be entitled to receive paid annual vacation in accordance with Company policy for other vice president level officers, but with vacation accrual of not less than two
(2) weeks per year. 
 5. Expenses. The Company will reimburse Executive for reasonable travel, entertainment and other business
expenses, including professional association fees, incurred by Executive in the furtherance of the performance of Executive’s duties hereunder. Executive is expected to travel frequently to the Company’s Tempe, Arizona office, and business
travel expense may include reasonable reimbursement for, or use of, an apartment in the Phoenix/Tempe, Arizona area. All reimbursements to Executive by the Company pursuant to this Section 5 shall be in accordance with the Company’s
expense reimbursement policy as in effect from time to time.

 6. Termination of Employment. In the event Executive’s employment with the Company terminates
for any reason, Executive will be entitled to any (a) unpaid Base Salary accrued up to the effective date of termination; (b) unpaid, but earned and accrued annual incentive for any completed fiscal year as of his termination of
employment; (c) pay for accrued but unused vacation; (d) benefits or compensation as provided under the terms of any employee benefit and compensation agreements or plans applicable to Executive; (e) unreimbursed business expenses
required to be reimbursed to Executive; and (f) rights to indemnification Executive may have under the Company’s Certificate of Incorporation, Bylaws and this Agreement as applicable. In the event Executive’s employment with the
Company terminates for any reason (other than Cause), Executive will be entitled to exercise any outstanding vested stock options until the first to occur of: (i) the date that is three months following the later of such termination of
employment or the date upon which Executive ceases to be a Service Provider (as defined in the Plan), (ii) the applicable scheduled expiration date of such award (in the absence of any termination of employment) as set forth in the award
agreement, or (iii) the ten (10) year anniversary of the award’s original date of grant. For purposes of clarity, the term “expiration date” shall be the scheduled expiration of the option agreement and not the period that
Executive shall be entitled to exercise such option. In addition, if the termination is by the Company without Cause, Executive will be entitled to the amounts and benefits specified in Section 7. 

7. Severance. 
 (a)
Termination Without Cause other than in Connection with a Change of Control. If Executive’s employment is terminated by the Company without Cause and such termination is not in Connection with a Change of Control, then, subject to
Section 8, Executive will receive: (i) continued payment of Executive’s Base Salary (subject to applicable tax withholdings) for six (6) months, such amounts to be paid in accordance with the Company’s normal payroll
policies; (ii) the actual earned cash incentive, if any, payable to Executive for the current year, pro-rated to the date of termination, with such pro-rated amount to be calculated by multiplying the current year’s Target Annual Incentive
by a fraction with a numerator equal to the number of days inclusive between the start of the current calendar year and the date of termination and a denominator equal to 365, such amounts to be paid at the same time as similar bonus payments are
made to the Company’s other executive officers, and (iii) reimbursement for premiums paid for continued health benefits for Executive (and any eligible dependents) under the Company’s health plans until the earlier of (A) six
(6) months, payable when such premiums are due (provided Executive validly elects to continue coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”)), or (B) the date upon which Executive and Executive’s
eligible dependents become covered under similar plans. For purposes of clarity, the Compensation Committee of the Board of Directors shall determine, in good faith, the extent to which any cash incentive has been earned by Executive. 

(b) Termination Without Cause or Resignation for Good Reason in Connection with a Change of Control. If Executive’s
employment is terminated by the Company without Cause or Executive terminates voluntarily for Good Reason and the termination is in Connection with a Change of Control, then, subject to Section 8, Executive will receive: (i) continued
payment of Executive’s Base Salary for the year in which the termination occurs (subject to applicable tax withholdings), for six (6) months, such amounts to be paid in accordance 

  
 -4-









 
with the Company’s normal payroll policies; (ii) the payment in an amount equal to 100% of Executive’s Target Annual Incentive for the year in which the termination occurs (subject
to applicable tax withholdings), such amounts to be paid in accordance with the Company’s normal payroll policies over the course of six (6) months; (iii) 100% of Executive’s then outstanding unvested Equity Awards will vest, and
(iv) reimbursement for premiums paid for continued health benefits for Executive (and any eligible dependents) under the Company’s health plans until the earlier of (A) six (6) months, payable when such premiums are due (provided
Executive validly elects to continue coverage under COBRA), or (B) the date upon which Executive and Executive’s eligible dependents become covered under similar plans. 

(c) Voluntary Termination or Termination for Cause. If Executive’s employment is terminated voluntarily or is terminated for
Cause by the Company, then, except as provided in Section 6, (i) all further vesting of Executive’s outstanding Equity Awards will terminate immediately and stock options shall be exercisable as provided in Section 6;
(ii) all payments of compensation by the Company to Executive hereunder will terminate immediately, and (iii) Executive will be eligible for severance benefits only in accordance with the Company’s then established plans. In the event
that Executive’s employment is terminated due to death or Disability, twenty-five percent (25%) of Executive’s then unvested Equity Awards shall vest. 
 (d) Resignation for Material Corporate Change. If within twelve (12) months following the Effective Date Executive voluntarily resigns because of a Material Corporate Change then, subject to
the terms of this Agreement including without limitation the conditions in Section 8, Executive will be entitled to the severance benefits described in Section 7(a) above. This Section 7(d) expires twelve (12) months following
the Effective Date. For purposes of this Section 7(d) Material Corporate Change means an unanticipated (as of the Effective Date), material change in the Company’s executive management team coupled with a significant, material reduction of
responsibilities as of the Effective Date. A sale, separation or spin-off of a portion of the Company’s business operations provided the Company remains a going concern and provided Executive’s duties, position and responsibilities with
respect to the remaining business operations are not materially reduced will also not be considered a Material Corporate Change. Executive will not resign for a Material Corporate Change without first providing the Company with written notice within
thirty (30) days of the event that Executive believes constitutes a Material Corporate Change specifically identifying the acts or omissions constituting the grounds for resignation under this Section 7(d) and a reasonable cure period of
not less than thirty (30) days. 
 8. Conditions to Receipt of Severance: No Duty to Mitigate. 

(a) Separation Agreement and Release of Claims. The receipt of any severance or other benefits pursuant to Section 7 will be
subject to Executive signing and not revoking a separation agreement and release of claims in a form acceptable to the Company and provided that such release of claims becomes effective and irrevocable no later than sixty (60) days following
the termination date (such deadline, the “Release Deadline”). The Company shall deliver such form to Executive within five (5) business days after the date of termination. No severance or other benefits pursuant to Section 7 will
be paid or provided until the separation agreement and 

  
 -5-









 
release of claims becomes effective and irrevocable. If the separation agreement and release of claims does not become effective by the Release Deadline, Executive will forfeit any rights to
severance or benefits under this Agreement. Any severance payments or benefits under this Agreement that would be considered Deferred Compensation Severance Benefits (as defined in Section 24), will be paid on, or, in the case of installments,
will not commence until, the sixtieth (60th) day
following Executive’s “separation from service”, or, if later, such time as required by Section 24. Any installment payments that would have been made to Executive during the sixty (60) day period immediately following
Executive’s “separation from service” but for the preceding sentence will be paid to Executive on the sixtieth (60th) day following Executive’s “separation from service” and the remaining payments will be made as
provided in this Agreement. If Executive should die before all of the severance amounts have been paid, such unpaid amounts will be paid in a lump-sum payment promptly following such event to Executive’s designated beneficiary, if living, or
otherwise to the personal representative of Executive’s estate. 
 (b) Non-solicitation and Non-competition. The
receipt of any severance or other benefits pursuant to Section 7 is subject to Executive agreeing that during the Employment Term and for twelve (12) months thereafter, Executive will comply with all of the restrictive covenants contained
in the Confidential Information Agreement (as defined in Section 12 below), including without limitation, the non-compete, non-solicitation of employees and non-solicitation of customers covenants contained in Section 5 of the Confidential
Information Agreement. 
 (c) Nondisparagement. During the Employment Term and for twelve (12) months thereafter,
Executive and the Company in its official communications will not knowingly and materially disparage, criticize, or otherwise make any derogatory statements regarding the other. The Company will instruct its officers and directors to not knowingly
and materially disparage, criticize, or otherwise make any derogatory statements regarding Executive. Notwithstanding the foregoing, nothing contained in this agreement will be deemed to restrict Executive, the Company or any of the Company’s
current or former officers and/or directors from providing factual information to any governmental or regulatory agency (or in any way limit the content of any such information) to the extent they are requested or required to provide such
information pursuant to applicable order, subpoena, law or regulation. 
 (d) Other Requirements. Executive’s
receipt of continued severance payments pursuant to Section 7 will be subject to Executive continuing to comply with the terms of the Confidential Information Agreement and the provisions of this Section 8. 

(e) No Duty to Mitigate. Executive will not be required to mitigate the amount of any payment contemplated by this Agreement, nor
will any earnings that Executive may receive from any other source reduce any such payment. 
 9. Excise Tax. In the event that the
benefits provided for in this Agreement constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and will be subject to the excise tax imposed by
Section 4999 of the Code (the “Excise Tax”), then Executive’s severance benefits payable under the terms of this Agreement will be either (a) delivered in full, or (b) delivered as to such lesser extent which would
result in no portion of such 

  
 -6-









 
severance benefits being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax, results in
the receipt by Executive on an after-tax basis, of the greatest amount of severance benefits. Any reduction in payments and/or benefits required by this Section 9 will occur in the following order: (1) reduction of cash payments;
(2) reduction of vesting acceleration of equity awards; and (3) reduction of other benefits paid or provided to Executive. In the event that acceleration of vesting of equity awards is to be reduced, such acceleration of vesting will be
cancelled in the reverse order of the date of grant for Executive’s equity awards. If two or more equity awards are granted on the same date, each award will be reduced on a pro-rata basis. 

10. Definitions. 
 (a) Cause. For purposes of this Agreement, “Cause” will mean: 

(i) Acts or omissions constituting gross negligence, recklessness or willful misconduct on the part of Executive with respect to
Executive’s obligations under this Agreement or otherwise relating to the business of the Company, or failure or refusal to carry out lawful directions from the CEO with respect to Executive’s obligations under this Agreement or otherwise
relating to the business of the Company; 
 (ii) Any act of personal dishonesty taken by Executive in connection with his
responsibilities as an employee of the Company with the intention or reasonable expectation that such action may result in the substantial personal enrichment of Executive;

civil or criminal securities law action or entering any cease and desist order with respect to such action (regardless of whether or not Executive admits or denies liability); 

(vi) Executive (A) obstructing or impeding; (B) endeavoring to obstruct, impede or improperly influence, or (C) failing
to materially cooperate with, any investigation authorized by the Board or any governmental or self-regulatory entity (an “Investigation”). However, Executive’s failure to waive attorney-client privilege relating to communications
with Executive’s own attorney in connection with an Investigation will not constitute “Cause”; 
 (vii)
Executive’s disqualification or bar by any governmental or self-regulatory authority from serving in the capacity contemplated by this Agreement or Executive’s loss of any governmental or self-regulatory license that is reasonably
necessary for Executive to perform his responsibilities to the Company under this Agreement, if (A) the disqualification, bar or loss continues for more than thirty (30) days, and (B) during that period the Company uses its


  
 -7-









 
good faith efforts to cause the disqualification or bar to be lifted or the license replaced. While any disqualification, bar or loss continues during Executive’s employment, Executive will
serve in the capacity contemplated by this Agreement to whatever extent legally permissible and, if Executive’s employment is not permissible, Executive will be placed on leave (which will be paid to the extent legally permissible); or

 (b) Change of Control. For purposes of this Agreement, “Change of Control” will mean the occurrence of any
of the following events: 
 (i) The consummation by the Company of a merger or consolidation of the Company with any other
corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities
of the surviving entity) more than 50% of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; 

(ii) The approval by the stockholders of the Company, or if stockholder approval is not required, approval by the Board, of a plan of
complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; or 
 (iii) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than Goldman Sachs and its related funds and entities, becoming
the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing 50% or more of the total voting power represented by the Company’s then outstanding voting securities.

 (c) Continuance Period. For purposes of this Agreement, “Continuance Period” will mean the period of time
beginning on the date of the termination of Executive’s employment and ending on the date on which Executive is no longer receiving Base Salary payments under Section 7.

(e) In Connection with a Change of Control. For purposes of this Agreement, a termination of Executive’s employment with the
Company is “in Connection with a Change of Control” if Executive’s employment is terminated within three (3) months prior to the execution of an agreement that results in a Change of Control or twelve (12) months following a
Change of Control. 
 (f) Good Reason. For purposes of this Agreement, “Good Reason” means Executive’s

without Executive’s written consent: 
 (i) A significant, material reduction of Executive’s duties, position, or
responsibilities, relative to Executive’s duties, position, or responsibilities in effect immediately prior to the Change of Control. A change of title alone is not Good Reason; 

  
 -8-









 (ii) A material reduction in Executive’s cash compensation (either Base Salary, or
Base Salary and Annual Incentive Target combined) as in effect immediately prior to such reduction. Notwithstanding the foregoing, a one-time reduction that also is applied to other similarly situated executive officers of the Company and which
one-time reduction reduces the cash compensation by a percentage reduction of 10% or less in the aggregate will not be deemed material and will not constitute “Good Reason”; 

(iii) A material change in the geographic location from which Executive must perform services (that is, a requirement that Executive
re-locate his permanent residence to a location other than the greater San Francisco Bay area, CA), it being recognized that Executive may routinely be required to travel in performance of his business duties; or 

(iv) A material breach by the Company (or its successor) of any material contractual obligation owed Executive pursuant to this
Agreement (including, without limitation, the failure of the Company to obtain the assumption of this Agreement by a successor).

Company’s Certificate of Incorporation or Bylaws, including, if applicable, any directors and officers insurance policies, with such indemnification to be on terms determined by the Board or any of its committees, but on terms no less favorable
than provided to any other Company executive officer or director and subject to the terms of any separate written indemnification agreement. 
 12. Confidential Information. Executive will execute the form of At-Will Employment, Confidential Information, Inventions Assignment and Arbitration Agreement, appended hereto as
Exhibit A (the “Confidential Information Agreement”). In the event of any inconsistency between the terms of this Agreement and the terms of the Confidential Information Agreement, this Agreement will prevail. 

13. Assignment. This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors and legal
representatives of Executive upon Executive’s death, and (b) any successor of the Company. Any such successor of the Company will be deemed substituted for the Company under the terms of this Agreement for all purposes. For this purpose,
“successor” means any person, firm, corporation, or other business entity which at any time, whether by purchase, merger, or otherwise, directly or indirectly acquires all or substantially all of the assets or business of the Company. None
of the rights of Executive to receive any form of compensation payable 

  
 -9-









 
pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance, or other disposition of
Executive’s right to compensation or other benefits will be null and void. This Section 13 will in no way prevent Executive from transferring any vested property he owns.

given (a) on the date of delivery if delivered personally; (b) one (1) day after being sent overnight by a well-established commercial overnight service, or (c) four (4) days after being mailed by registered or certified

 16. Arbitration. The parties agree that any and all disputes arising out of the terms of this Agreement, Executive’s employment by the Company, Executive’s service as an officer or
director of the Company, or Executive’s compensation and benefits, their interpretation and any of the matters herein released, will be subject to binding arbitration in accordance with the terms of section 12 of the Confidential Information
Agreement. The Parties further agree that the prevailing party in any arbitration will be entitled to injunctive relief in any court of competent jurisdiction to enforce the arbitration award. The parties hereby agree to waive their right to have

 17. Integration. This Agreement, together with the Confidential Information Agreement
and the forms of equity award agreements that describe Executive’s outstanding Equity Awards, represents the entire agreement and understanding between the parties as to the subject matter herein and supersedes all prior or contemporaneous
agreements whether written or oral. No waiver, alteration, or modification of any of the provisions of this Agreement will be binding unless in a writing and signed by duly authorized representatives of the parties hereto. In entering into this
Agreement, no party has relied on or made any representation, warranty, inducement, promise, or understanding that is not in this Agreement. To the extent that any provisions of this Agreement conflict with those of any other agreement to be signed
upon Executive’s hire, the terms in this Agreement will prevail. 
 18. Waiver of Breach. The waiver of a breach of
any term or provision of this Agreement, which must be in writing, will not operate as or be construed to be a waiver of any other previous or subsequent breach of this Agreement. 

19. Survival. The Confidential Information Agreement and the Company’s and Executive’s responsibilities under Sections
6, 7, 8, and 11 will survive the termination of this Agreement. 
 20. Headings. All captions and Section headings

 23. Acknowledgment. Executive acknowledges that he has had the opportunity to discuss this matter with and obtain advice from his private attorney, has had sufficient time to, and has carefully
read and fully understands all the provisions of this Agreement, and is knowingly and voluntarily entering into this Agreement. 

24. Code Section 409A. 
 (a) Notwithstanding anything to the contrary in this Agreement, no severance payable to Executive, if any, pursuant to this Agreement, when considered together with any other severance payments or
separation benefits that are considered deferred compensation under Section 409A of the Code and the final regulations and any guidance promulgated thereunder (“Section 409A”) (together, the “Deferred Compensation Separation
Benefits”) will be payable until Executive has a “separation from service” within the meaning of Section 409A. 
 (b) Notwithstanding anything to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of Section 409A at the time of Executive’s termination (other
than due to death), then the Deferred Compensation Separation Benefits that are payable within the first six (6) months following Executive’s separation from service, will become payable on the first payroll date that occurs on or after
the date six (6) months and one (1) day following the 

  
 -11-









 
date of Executive’s separation from service. All subsequent Deferred Compensation Separation Benefits, if any, will be payable in accordance with the payment schedule applicable to each
payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following Executive’s separation from service but prior to the six (6) month anniversary of the separation, then any payments delayed in accordance with
this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive’s death and all other Deferred Compensation Separation Benefits will be payable in accordance with the payment schedule applicable
to each payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. 

(c) Any amount paid under this Agreement that satisfies the requirements of the “short-term deferral” rule set forth in
Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Compensation Separation Benefits for purposes of clause (i) above. 
 (d) Any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations
that do not exceed the Section 409A Limit will not constitute Deferred Compensation Separation Benefits for purposes of clause (i) above. For purposes of this Agreement, “Section 409A Limit” will mean the lesser of two
(2) times: (i) Executive’s annualized compensation based upon the annual rate of pay paid to Executive during the Company’s taxable year preceding the Company’s taxable year of Executive’s termination of employment as
determined under Treasury Regulation 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to
Section 401(a)(17) of the Code for the year in which Executive’s employment is terminated. 
 (e) The foregoing
provisions are intended to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities
herein will be interpreted to so comply. The Company and Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of
any additional tax or income recognition prior to actual payment to Executive under Section 409A.”
