(the “Company”) effective on the date set forth in Section 8 below (“Effective Date”) relating to Employee’s employment and termination of employment with the Company. When used herein, the term “Company” includes each and every officer, director, employee, agent, parent corporation(s), subsidiary corporation(s), wholly owned companies, affiliate(s) and division(s), their successors, assigns, beneficiaries, servants, legal representatives, insurers and heirs of Limelight Networks, Inc.

A.Limelight and Employee are parties to an Employment Agreement dated as of July 23, 2013, and amended as of June 19, 2015 (the “Employment Agreement”), and are also parties to an At-will Employment, Confidential information, Invention Assignment and Arbitration Agreement (the “Confidential Information Agreement”).

B.Employee’s employment by Limelight is terminating and Employee is delivering this Agreement in accordance with Section 8(a) of the Employment Agreement.

C.The Company desires to retain Employee as a consultant after the Separation Date (as defined below) to assist with the transition of his duties.

1.    Separation from Employment. Employee’s duties as Chief Financial Officer and employment with the Company will terminate effective December 4, 2015, (“Separation Date”). Company will pay Employee all wages and accrued vacation earned by Employee through the Separation Date as contemplated in Section 6 of the Employment Agreement. Employee acknowledges that, except as set out herein, the Company owes no other commissions, wages, bonuses, vacation pay, sick pay, or benefits to Employee. This Agreement is intended to settle, resolve and release any and all claims stemming from or related to Employee’s employment with Company, Employee’s termination of employment, including, but not limited to, any and all claims for amounts due to Employee from Company in terms of wages, fees, commissions, severance payments, bonuses and/or benefits of any kind.

2.    Interim and Consulting Periods. Employee agrees that he will continue to work diligently and in good faith between the effective date and the Separation Date, including assisting and preparing his successor, interim successor or other persons identified by the Company’s Chief Executive Officer to assume the responsibilities of Chief Financial Officer and to effect a smooth transition of his duties and responsibilities to such person. During the period beginning on the Separation Date, and ending on the earliest to occur of (i) June 30, 2016, (ii) the date Employee commences full-time employment with any third party, or (iii) the date this Agreement is terminated due to a breach by Employee, (the “Consulting Period”) Executive agrees, subject to his reasonable availability and upon reasonable request by the Company, to provide advice and consultation regarding the continued transition of his former duties and responsibilities as Chief Financial Officer, and as such, shall remain a service provider as defined in the Company’s 2007 Equity Incentive Plan during the Consulting Period. The parties agree that such advisory and consulting work will not exceed 100 hours during the Consulting Period, without the Executive’s prior written consent. Executive acknowledges and agrees that all work under this Section 2 will be subject to and covered by Confidential Information Agreement, and all covenants contained therein that are otherwise designed to terminate upon Executive’s Separation Date will continue until the expiration of the Consulting Period, as if Executive were still an employee of the Company.

3.    Transition Consideration and Continued Vesting of Equity Awards. In addition to the wages set forth in paragraph 1, and for, and in consideration of, the covenants, promises and releases by Employee in this Agreement, and subject to compliance with any and all prerequisites expressly set forth herein and in the Employment Agreement (including without limitation Employee’s continued compliance with the restrictive covenants set forth in the Employment Agreement and Confidential Information Agreement), Company agrees to (i) pay to Employee the actual earned cash incentive, if any, payable to Employee for the current year, pro-rated to the Separation Date, with such pro-rated amount to be calculated by multiplying the actually earned portion of the Employee’s corporate bonus 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 (ii) continue the vesting, in accordance with the existing vesting schedules, of all of Executive’s outstanding equity awards through the expiration of the Consulting Period. All equity awards unvested as of the end of the Consulting Period will be forfeited on that date.

4.    Other Benefits. Employee’s participation in the Company’s group medical and dental programs ceases on the Separation Date.  As of such date, Employee is responsible for paying his entire monthly COBRA premiums. Employee must elect to receive COBRA if he wants continuation coverage under the Company’s group health benefits programs.  Employee’ right to COBRA and the time for electing COBRA and making the required COBRA payments will be explained in a separate COBRA notice package.  Also as of the Separation Date, Employee is no longer eligible to participate in any other benefit programs offered by the Company, including, but not limited to, vacation, 401(k) plan, short-term and long-term disability, accidental death and dismemberment and life and dependent life insurance programs.

5.    Confidentiality. Employee agrees that the nature, terms, conditions, and substance of this Agreement are strictly confidential and shall be kept confidential by Employee and his representatives, attorneys, and spouse, and shall not be disclosed at any time to any other person, except as necessary in the course of seeking Legal counsel, preparing and filing appropriate tax returns or dealing with federal or state taxing authorities. In addition, any term hereof may be disclosed during any lawsuit or other proceeding brought to enforce the terms of this Agreement, or as required by a lawfully issued subpoena or court order. Employee agrees that if he finds it necessary to disclose the terms of this Agreement to his representatives, attorneys, or spouse, he will inform such persons that they are under an obligation to maintain the confidentiality of such information.

6.    Mutual Non-Disparagement. Employee agrees to refrain from any disparagement, defamation, libel, or slander of Company, its employees, officers, directors or shareholders, and agrees to refrain from any unlawful interference with the contracts of Company. The Company agrees to refrain from making any disparaging statements about Employee. Employee shall direct any inquiries by potential future employers to the Company’s human resources department, which shall provide only his last position and dates of employment. Notwithstanding the foregoing, nothing contained in this agreement will be deemed to restrict Employee, 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 or from otherwise providing truthful information in response to any subpoena or other legal process.

7.    Full General Release of Claims. Employee, for himself, his marital community, and his heirs, successors and assigns, irrevocably and unconditionally releases and forever discharges Limelight Networks, Inc., its parents, subsidiaries and affiliates, and all of their successors, assigns, officers, directors, representatives, agents, employees, associates, and all other persons acting for or on behalf of any of them, from any and all claims, complaints, liabilities, obligations, promises, agreements, damages, causes of action, costs, losses, debts and expenses of every kind, in law or in equity, whether known or unknown, foreseen or unforeseen, from the beginning of time to the date of this Agreement, including any and all claims in connection with Employee’ employment with the Company and separation from employment with the Company. Except as otherwise expressly provided herein, this general release is a full and final bar to any claims Employee may have against the Company, including, without limitation, any claims:

The parties intend that the release of claims in this Agreement extend to all claims Employee may have whether known or unknown, and in furtherance of this intention the Employee acknowledges that he understands the provisions of California Civil Code Section 1542, which is reproduced below, and expressly waives the rights and benefits of that Section:

California Civil Code Section 1542: A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.

 

8.    Acknowledgment of Waiver of Claims under the Age Discrimination in Employment Act (ADEA). Employee acknowledges that he is waiving and releasing any rights he may have under the Age Discrimination in Employment Act of 1967 (“ADEA”), and that this waiver and release is knowing and voluntary. Employee agrees that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the Effective Date of this Agreement. Employee acknowledges that the consideration given for this waiver and release is in addition to anything of value to which Employee was already entitled. Employee further acknowledges that he has been advised by this writing that: (a) he should consult with an attorney prior to executing this Agreement; (b) he has twenty-one (21) days within which to consider this Agreement and agrees that any non-material change to the terms herein from the date of first offer to the Effective Date do not re-start, extend, or interrupt the 21 day consideration period; (c) he has seven (7) days following his execution of this Agreement to revoke this Agreement; (d) this Agreement shall not be effective until signed by Employee, and until after the revocation period has expired (the “Effective Date”); (e) nothing in this Agreement prevents or precludes Employee from challenging or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties, or costs for doing so, unless specifically authorized by federal law; and (f) the payments and continued vesting set forth in paragraph 3 above are contingent upon Employee’s agreement to and the effectiveness of this ADEA waiver. In the event Employee signs this Agreement and returns it to Company in less than the 21-day period identified above, Employee hereby acknowledges that he has freely and voluntarily chosen to waive the time period allotted for considering this Agreement

9.    Voluntary Action. Employee acknowledges that he has read each paragraph of this Agreement and understands his rights and obligations. Employee further acknowledges and agrees that: (a) this Agreement is written in a manner understandable to him; (b) this Agreement is granted in exchange for consideration which is in addition to anything of value to which Employee is otherwise entitled; (c) he has been given a reasonable opportunity to consider and review this Agreement and consult with an attorney of his choice; and (d) his signature on this Agreement is knowing and voluntary.

(f) Equitable Remedy/Enforcement.     The parties agree that money damages would not be a sufficient remedy for any breach of the confidentiality and non-disclosure and non-disparagement provisions herein, and that the non-breaching party in such case will be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any such breach, and alleged breaching party further agrees to waive any requirement for the securing or posting of any bond in connection with such remedy.
