WHEREAS, the parties hereto desire to enter into this Agreement to provide for the employment of the Employee by the Employer and for certain other matters in connection with such employment, all as more fully set forth in this Agreement.

NOW, THEREFORE, in consideration of the premises and covenants set forth herein, and intending to be legally bound hereby, the parties to this Agreement hereby agree as follows:

1.    Employment; Term. The Company agrees to employ the Executive, and the Executive agrees to serve in the employ of the Company, in the position and with the responsibilities, duties and authority set forth in Section 2 and on the other terms and conditions set forth in this Agreement. The Executive’s employment shall constitute “at will” employment. Subject to Section 7, the Executive’s employment may be terminated at any time and for any reason. Certain rights and obligations of the Executive and the Company shall survive the termination of Executive’s employment, as set forth in this Agreement.

2.    Position, Duties. The Executive shall serve in the position of                      of the Company. The Executive shall perform, faithfully and diligently, such service and duties, and shall have such responsibilities, appropriate to said position, as shall be assigned to him. The Executive shall report directly to the Chief Executive Officer of the Company. The Executive agrees to devote his entire business time, best efforts, skills and attention to fulfilling the performance of his duties and responsibilities hereunder. The Executive shall be based in                     , except for travel required by Company business. Nothing set forth herein shall prohibit the Executive from engaging in personal investing activities or, upon the prior written approval of the Board, serving on the boards of directors of other entities whose businesses are not competitive with the Company, provided that such activities do not interfere in any material respect with the services to be provided by the Executive under this Agreement.

3.    Salary. In consideration of the performance by the Executive of the services set forth in Section 2 and his observance of the other covenants set forth herein, the Company shall pay to the Executive, and the Executive shall accept, a base salary at the rate of $             per annum, payable in accordance with the standard payroll practices of the Company. The Executive’s salary shall be reviewed at least annually for potential increase, in accordance with the Company’s practice in the U.S.

4.    Bonus. During the employment term, the Executive will be eligible to earn an annual bonus award (“Annual Bonus”), with a target bonus amount equal to     % of Executive’s Base Salary (the “Target Bonus”) based upon the achievement of performance goals

established by the Board. All Annual Bonus amounts shall be determined and paid in accordance with the terms and conditions of the Company’s annual incentive plan or policy. In addition, the Executive will be eligible to participate in the Company’s long-term incentive plans available to senior executives of the Company in accordance with the terms and conditions of such plans, as in effect from time to time.

In the event the Company is required to prepare a restatement of its financial results for a fiscal year and the Board in good faith determines that the need for such restatement would require reduction, cancellation, forfeiture, or recoupment of an Annual Bonus, Executive shall, within 60 days of receiving notice of such Board determination (which notice shall state the reasons for the need for the restatement, identify the misconduct and include calculations of the impact thereof), reimburse the Company, net of taxes, for all excess remuneration (as defined below) received by Executive in connection with the Annual Bonus received by Executive with respect to such fiscal year. For purposes of this provision, the term “excess remuneration” means the excess of the Annual Bonus payment made to Executive for such fiscal year over the payment that would have been made to Executive for such fiscal year had Executive’s payment been calculated based on the financial statements as restated, as determined in the good faith discretion of the Board. All Annual Bonus awards shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with (i) any clawback, forfeiture or other similar policy adopted by the Board or the Compensation Committee and as in effect from time to time; and (ii) applicable law.

5.    Expense Reimbursement. During the employment term, the Company shall reimburse the Executive for all reasonable and necessary out-of-pocket expenses incurred by him in connection with the performance of his duties hereunder, upon the presentation of proper accounts therefor in accordance with the Company’s policies (but in no event later than the last day of the calendar year next following the calendar year in which the expenses were incurred).

6.    Benefits.

6.1    Generally. During the employment term, the Executive will be eligible to participate in all benefit plans and programs offered by the Company from time to time to its employees of comparable seniority, subject to the terms and conditions of such plans and programs as in effect from time to time. Such plans and programs currently include the following:

Paid holidays may be taken in accordance with the holiday policy and schedule of the Company as from time to time in effect.

In addition, the Company shall pay to the estate or other legal representative of the Executive a lump sum, pro rata portion of any Annual Bonus that Executive would have been entitled to receive pursuant to Section 4 for the fiscal year in which such termination occurs, based upon the percentage of the fiscal year that shall have elapsed through the date of Executive’s termination of employment, calculated on the actual performance for the fiscal year in which termination occurs (the “Pro-Rata Bonus”), payable when such Annual Bonus would have otherwise been payable had Executive’s employment not terminated. Rights and benefits of the estate or other legal representative of the Executive under the benefit plans and programs of the Company shall be determined in accordance with the terms and conditions of such plans and programs. Neither the estate nor other legal representative of the Executive nor the Company shall have any further rights or obligations under this Agreement except as provided in this Section 7.1.

7.2    Disability. Upon Executive’s permanent disability, the Company shall have the right to terminate Executive’s employment with the Company hereunder immediately with written notice. For these purposes, “permanent disability” shall mean the Executive failing to perform his duties on a full-time basis for a period of more than six (6) consecutive months during any 12-month period due to a physical or mental disability or infirmity, as determined by the Board and supported by the opinion of a physician. The Executive shall fully cooperate with the physician retained to furnish such opinion, including submitting to such examinations and tests as may be requested by the physician. Notwithstanding the foregoing, in the event that as a result of mental or physical incapacity Executive earlier incurs a “separation from service”

within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), Executive will be deemed to have a termination of employment by reason of permanent disability under this Agreement. In the event of Executive’s termination by reason of permanent disability, the Company shall pay to the Executive, within ninety (90) days of the Executive’s termination, (i) the salary accrued to the date of such termination and not theretofore paid and (ii) any earned but unpaid Annual Bonus for the fiscal year preceding the fiscal year in which such termination occurs. In addition, the Company shall pay to the Executive the Pro-Rata Bonus, payable when such Annual Bonus would have otherwise been payable had Executive’s employment not terminated. Rights and benefits of the Executive under the benefit plans and programs of the Company shall be determined in accordance with the terms and conditions of such plans and programs. Neither the Executive nor the Company shall have any further rights or obligations under this Agreement, except as provided in this Section 7.2 and Section 8.

7.3    Termination by the Company For Cause. If the Company terminates the Executive’s employment for Cause (as defined in Section 9(a)), the Company shall pay to the Executive, within ninety (90) days of the Executive’s termination, the salary accrued to the date of termination and not theretofore paid and any earned but unpaid Annual Bonus for the fiscal year preceding the fiscal year in which such termination occurs. Executive will not be entitled to the Pro-Rata Bonus. Rights and benefits of the Executive under the benefit plans and programs of the Company shall be determined in accordance with the terms and conditions of such plans and programs. Neither the Executive nor the Company shall have any further rights or obligations under this Agreement, except as provided in this Section 7.3 and Section 8.

7.4    Termination by the Company Without Cause Prior to a Change in Control. If the Company terminates the Executive’s employment prior to a Change in Control (as defined in Section 9(c)), other than pursuant to Section 7.1 (Death), 7.2 (Disability), or 7.3 (Cause), the Company shall pay to the Executive, within ninety (90) days of the Executive’s termination, the salary accrued to the date of termination and not theretofore paid to the Executive and any earned but unpaid Annual Bonus for the fiscal year preceding the fiscal year in which such termination occurs. In addition, Executive shall be entitled to receive a lump sum pro rata portion of the Annual Bonus, if any, that Executive would have been entitled to receive pursuant to Section 4 hereof for the fiscal year in which such termination occurs (but only to the extent of achievement of the applicable performance standards for such year) based upon the percentage of the fiscal year that shall have elapsed through the date of Executive’s termination of employment, payable when such Annual Bonus would have otherwise been payable had Executive’s employment not terminated; provided, however, that to the extent the Annual Bonus is subject to the exercise of negative discretion, such discretion shall not be exercised to reduce Executive’s Annual Bonus by a greater percentage than is applied generally to senior executives subject to such discretion. In addition, subject to Executive’s compliance with the provisions of Section 8 and in lieu of any severance otherwise payable to Executive under any severance plan or policy maintained by the Company, the Company shall:

(i)    pay to Executive for the duration of the Severance Period (as defined below) a monthly amount, in accordance with the Company’s normal payroll practice, equal to the sum of (x) his monthly base salary and (y) 1/12th of his average Annual Bonus paid with respect to the last three fiscal years ending immediately prior to his termination of

employment. For the purposes of calculating the three-year average Annual Bonus, the following shall apply: i) for each such previous year, the most recent target bonus percentage; the most recent salary and the actual performance payout factor for such preceding fiscal years shall be used; ii) for any years that such bonus amount or bonus percentage is not available, the target bonus or percentage based upon the most recent target percentage shall be used; and iii) for any partial bonus years within the three preceding completed fiscal years, such bonus year shall be adjusted as if the full year bonus was earned using the most recent target percentage (the “Average Bonus Calculation Principles”). The Severance Period shall be twelve (12) months (the “Severance Period”);

(ii)    continue payment of Executive’s Health Care Benefits under COBRA until the earlier of (x) the date on which Executive’s COBRA eligibility ceases, or (y) the twelve (12) month anniversary of Executive’s termination of employment;

(iii)    pay a lump-sum amount of $10,000 for outplacement services, which shall be paid within 60 days of Executive’s termination of employment;

(iv)    pay to the Executive, at the end of the twelve (12) month period following termination of employment, an amount equal to the maximum amount that the Company would have been obligated to contribute on his behalf as matching contributions to the Company’s qualified and non-qualified retirement plans for such twelve (12) month period, based on the Executive’s most recent deferral elections with respect to such plans, plus the maximum amount that the Company would have been obligated to contribute on his behalf as non-elective contributions to the Company’s qualified and non-qualified retirement plans for such twelve (12) month period, based on his salary in effect immediately prior to his termination of employment, in each case to the extent such amounts would have been vested at the end of the twelve (12) month period under the terms of such plans had he remained in employment for such period.

The rights and benefits of the Executive under the benefit plans and programs of the Company (other than any severance plan or policy) shall be determined in accordance with the terms and conditions of such plans and programs. Neither the Executive nor the Company shall have any further rights or obligations under this Agreement, except as provided in this Section 7.4 and Section 8.

7.5    Termination by the Company Without Cause Following a Change in Control. If, following the occurrence of a Change in Control, the Company (or successor) terminates the Executive’s employment other than pursuant to Section 7.1 (Death), 7.2 (Disability), or 7.3 (Cause), the Company (or successor) shall pay to the Executive, within sixty (60) days of the Executive’s termination, the salary accrued to the date of termination and not theretofore paid to the Executive and any earned but unpaid Annual Bonus for the fiscal year preceding the fiscal year in which such termination occurs. In addition, Executive shall be entitled to receive a lump sum pro rata portion of the Annual Bonus, if any, that Executive would have been entitled to receive pursuant to Section 4 hereof for the fiscal year in which such

termination occurs (but only to the extent of achievement of the applicable performance standards for such year) based upon the percentage of the fiscal year that shall have elapsed through the date of Executive’s termination of employment, payable when such Annual Bonus would have otherwise been payable had Executive’s employment not terminated; provided, however, that to the extent the Annual Bonus is subject to the exercise of negative discretion, such discretion shall not be exercised to reduce Executive’s Annual Bonus by a greater percentage than is applied generally to senior executives subject to such discretion. In addition, subject to Executive’s compliance with the provisions of Section 8 and in lieu of any severance otherwise payable to Executive under any severance plan or policy maintained by the Company, the Company (or successor) shall:

(i)    pay the Executive, within sixty (60) days of termination, a cash lump sum payment in an amount equal to the number of months (including partial months) in the Severance Period multiplied by the sum of (x) his monthly base salary at the rate in effect immediately prior to Executive’s termination of employment and (y) 1/12^th of his average Annual Bonus paid with respect to the last three fiscal years ending immediately prior to his termination of employment. For the purposes of calculating the three-year average Annual Bonus, the calculation shall be based upon the Average Bonus Calculation Principles set forth above;

(ii)    continue payment of Executive’s Health Care Benefits under COBRA until the earlier of (x) the date on which Executive’s COBRA eligibility ceases, or (y) the twelve (12) month anniversary of Executive’s termination of employment;

(iii)    pay, a lump-sum amount of $10,000 for outplacement services, which shall be paid within 60 days of Executive’s termination of employment; and

(iv)    pay to the Executive, at the end of the twelve (12) month period following termination of employment, an amount equal to the maximum amount that the Company (or successor) would have been obligated to contribute on his behalf as matching contributions to the Company’s (or successor’s) qualified and non-qualified retirement plans for such twelve (12) month period, based on the Executive’s most recent deferral elections with respect to such plans, plus the maximum amount that the Company (or successor) would have been obligated to contribute on his behalf as non-elective contributions to the Company’s (or successor’s) qualified and non-qualified retirement plans for such twelve (12) month period, based on his salary in effect immediately prior to his termination of employment, in each case to the extent such amounts would have been vested at the end of the twelve (12) month period under the terms of such plans had he remained in employment for such period.

Notwithstanding the foregoing provisions of this Section 7.6, if the Change in Control fails to qualify as a “change of control” for purposes of Section 409A of the Internal Revenue Code or if Section 409A otherwise so requires, the accrued and unpaid salary and Annual Bonus referred to in the first paragraph of this Section 7.6 shall be paid within ninety (90) days of the Executive’s termination, and the amounts described in clauses (x) and (y) of clause (i) of this Section 7.6 shall be paid monthly, in accordance with the company’s normal payroll practice, for the duration of the Severance Period.

The rights and benefits of the Executive under the benefit plans and programs of the Company (other than any severance plan or policy) shall be determined in accordance with the terms and conditions of such plans and programs. Neither the Executive nor the Company shall have any further rights or obligations under this Agreement, except as provided in this Section 7.6 and Section 8.

For the avoidance of doubt, it is understood and agreed that if a Change of Control occurs after the Executive’s termination of employment and his termination was not in anticipation of such Change of Control, the provisions of this Section 7.6 shall not apply.

7.6    Release. Notwithstanding anything in this Agreement to the contrary, the Company’s obligations under Sections 7.4, 7.5 and 7.6 shall terminate if Executive does not execute and deliver to the Company a release substantially in the form attached hereto as Appendix A within [forty-five (45) days] of termination of employment or revokes such release within any applicable revocation period.

7.7    Voluntary Resignation and Other Termination. If, whether prior to or following a Change in Control, the Executive’s employment with the Company terminates for any reason other than pursuant to Section 7.1 (Death), 7.2 (Disability), 7.3 (Cause), 7.4 (Without Cause), or 7.5 (Without Cause Following a Change of Control), including by reason of voluntary resignation by the Executive, the Company shall pay to the Executive, within ninety (90) days of the Executive’s termination, the salary accrued to the date of termination and not theretofore paid and any earned but unpaid Annual Bonus for the fiscal year preceding the fiscal year in which such termination occurs. Executive will not be entitled to any portion of the Annual Bonus for the fiscal year in which such termination occurs. Rights and benefits of the Executive under the benefit plans and programs of the Company shall be determined in accordance with the terms and conditions of such plans and programs. Neither the Executive nor the Company shall have any further rights or obligations under this Agreement, except as provided in this Section 7.8 and Section 8.

7.8    Special 409A Provisions. Notwithstanding any provision of this Agreement to the contrary, if Executive is a specified employee within the meaning of Section 409A, as determined by the Board of Directors of the Company in accordance with Section 409A, any amounts payable under this Agreement or any other payments to which Executive may be entitled on account of a “separation from service” within the meaning of Section 409A which constitute “deferred compensation” within the meaning of Section 409A and which are otherwise scheduled to be paid during the first six months following Executive’s termination of employment (other than any payments that are permitted under Section 409A to be paid within six months following termination of employment of a specified employee) shall be suspended until the six-month anniversary of Executive’s termination of employment, at which time all payments that were suspended shall be paid to Executive in a lump sum, together with interest on each suspended payment at the prime rate (as reported in the Wall Street Journal) from the date of suspension to the date of payment. For purposes of Section 409A, each payment under this Section 7 will be treated as a separate and distinct payment and any installment payment pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any

amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A. Payment or reimbursement of each of the business expenses and tax gross-up payments called for by this Agreement with respect to any calendar year shall not affect the amount eligible for payment or reimbursement in any other calendar year, and such payments and reimbursements may not be exchanged for cash or another benefit. If any amounts are due to be paid to Executive within a specified period, the date of payment within such period shall be in the sole discretion of the Company.

7.9    Section 280G. (a) Notwithstanding any provision of this Agreement to the contrary, if any of the payments or benefits received or to be received by the Executive in connection with the Executive’s termination of employment in respect of a Change in Control, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company (all such payments and benefits, being hereinafter referred to as the “Total Payments”), would be subject to the excise tax (the “Excise Tax”) imposed under Section 4999 of the Code, the Executive shall receive the Total Payments and be responsible for the Excise Tax; provided, however that the Executive shall not receive the Total Payments and the Total Payments shall be reduced to the Safe Harbor Amount (defined below) if (1) the net amount of such Total Payments, as so reduced to the Safe Harbor Amount (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments) is greater than or equal to (2) the net amount of such Total Payment without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which the Executive would be subject in respect of such unreduced Total Payments). The “Safe Harbor Amount” is the amount to which the Total Payments would hypothetically have to be reduced so that no portion of the Total Payments would be subject to the Excise Tax.

(b)    For purposes of determining whether any of the Total Payments will be subject to the Excise Tax and the amount of such Excise Tax, (1) all of the Total Payments shall be treated as “parachute payments” (within the meaning of Section 280G(b)(2) of the Code) unless, in the opinion of tax counsel (“Tax Counsel”) selected by the accounting firm which was, immediately prior to the Change in Control, the Company’s independent auditor (the “Auditor”), such payments or benefits (in whole or in part) do not constitute parachute payments, including by reason of Section 280G(b)(4)(A) of the Code, (2) all “excess parachute payments” within the meaning of Section 280G(b)(1) of the Code shall be treated as subject to the Excise Tax unless, in the opinion of Tax Counsel, such excess parachute payments (in whole or in part) represent reasonable compensation for services actually rendered (within the meaning of Section 280G(b)(4)(B) of the Code) in excess of the base amount (within the meaning of Section 280G(b)(3) of the Code) allocable to such reasonable compensation, or are otherwise not subject to the Excise Tax, and (3) the value of any noncash benefits or any deferred payment or benefit shall be determined by the Auditor in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. If the Auditor is prohibited by applicable law or regulation from performing the duties assigned to it hereunder, then a different auditor, acceptable to both the Company and the Executive, shall be selected. The fees and expenses of Tax Counsel and the Auditor shall be paid by the Company.

(c)    In the event it is determined that the Safe Harbor Amount is payable to the Executive, then the severance payments provided under Section 7.6 which are cash shall first be reduced on a pro rata basis, and the non-cash severance payments shall thereafter be reduced on a pro rata basis, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax.

8.    Restrictive Covenants.

In consideration of the good and valuable consideration set forth herein, the Executive contemporaneously with the execution of this Agreement will sign the Non-Solicitation, Non-Compete, Confidentiality and Intellectual Property Agreement attached hereto as Appendix B.

9.    Non-Disparagement.

Executive agrees not to make written or oral statements about the Company, its subsidiaries or affiliates, or its directors, executive officers or non-executive officer employees that are negative or disparaging. The Company, its subsidiaries and affiliates shall not, and the Company shall instruct its directors and executive officers to not, make written or oral statements about Executive that are negative or disparaging. Notwithstanding the foregoing, nothing in this Agreement shall preclude Executive, the Company, its subsidiaries and affiliates, and the Company’s directors and executive officers from communicating or testifying truthfully to the extent required by law to any federal, state, provincial or local governmental agency or in response to a subpoena to testify issued by a court of competent jurisdiction.

10.    Cooperation.

Nothing in this Section shall be construed to limit in any way any rights Executive may have at applicable law not to provide testimony with regard to specific matters. Unless required by law or legal process, Executive will not knowingly or intentionally furnish information to or cooperate with any non-governmental entity (other than the Company) in connection with any potential or pending proceeding or legal action involving matters arising during Executive’s employment with the Company and its affiliates. The Company will reimburse Executive for any reasonable, out-of-pocket travel, hotel and meal expenses incurred in connection with Executive’s performance of obligations pursuant to this

Section for which Executive has obtained prior approval from the Company. Nothing in this Section or any other agreement by and between the Parties is intended to or shall preclude or in any way limit or restrict Executive from providing accurate and truthful testimony or information to any governmental agency.

WHEREAS, the Company is offering employment or continued employment to Employee, which is good and valuable consideration for this Agreement, including as set forth in the Employment Agreement, dated October 1, 2016;

NOW THEREFORE, in consideration of the mutual promises and covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending legally to be bound, agree to the foregoing and as follows:

1. Restrictive Covenants.

(a) Confidentiality. Employee agrees that both during and at all times after Employee’s employment with the Company, Employee will not disclose to any third party or use in any way (except in performing Employee’s duties while employed by the Company and in the interests of the Company and/or its affiliates) any confidential information, proprietary information, trade secrets, or other legally protectable information belonging to the Company or third party confidential information made available during Employee’s employment including, without limitation, information related to Company’s contractors, customers, licensors, subscribers, distributors or other vendors (“Customers”), regardless of the form in which such information is maintained, whether in hard-copy or electronic form, and regardless of whether such information constitutes an original or a copy. This includes, without limitation: Customer or supplier lists; research; financial, purchasing, and business planning information; financial and

business projections and plans; drawings and designs; marketing and promotional information, ideas and strategies; marketing surveys and analyses; technologies; budgets; pricing policies, plans and strategies; invoices; actual and projected revenues and profits; Customer identities and Customer lists; Customer documents, files, and accounts; information relating to the Company’s personnel or any other personnel data or information; the terms or structure of the Company’s contracts and agreements with Customers, including draft or prospective contracts; information relating to the Company’s products and services; and any other information relating to the Company and its products, services or contracts that Employee acquired as a result of Employee’s employment with the Company and that is not generally known or available to the public. Notwithstanding anything in this Agreement or any code of conduct or ethics, disclosure policy or other code, policy or similar document of the Company to the contrary, nothing herein or therein shall restrict Employee from reporting to the Securities and Exchange Commission, or communicating directly with its staff, about a possible securities law violation.

(b) No Solicitation of Employees. Employee agrees that, both during Employee’s employment with the Company and for a period of one (1) year following the termination of Employee’s employment with the Company at any time and for any reason, Employee will not, directly or indirectly, on Employee’s own behalf or on behalf of any other person or entity (regardless of who first initiates the communication), hire or solicit to hire for employment or consulting or other provision of services, any person who is actively employed or engaged (or in the preceding six (6) months was actively employed or engaged) by the Company. This includes, but is not limited to, inducing or attempting to induce, or influencing or attempting to influence, any person employed or engaged by the Company to terminate his or her relationship with the Company; helping to identify or evaluate Company employees for recruitment away from the Company; and helping any person or entity hire an employee away from the Company.

(c) No Solicitation of Customers. Employee agrees that, both during Employee’s employment and for a period of one (1) year following the termination of Employee’s employment with the Company at any time and for any reason, Employee will not directly or indirectly, on Employee’s own behalf or on behalf of any other person or entity, solicit the business of or provide services or goods similar to the services or goods provided by the Company to any Customer or any other entity with which the Company has an agreement to perform services or provide goods during the six (6) month period prior to Employee’s separation from the Company. Employee further agrees not to directly or indirectly contact any Customers for the purpose of soliciting such Customer to purchase or license a product or service that is the same as, similar to or in competition with those products and/or services offered, made, or rendered by the Company.

(d) Non-Competition. Employee understands and agrees that the Company has invested or will invest significant resources and time to train and develop Employee’s skills and knowledge specific to the Company’s business. The Company has invested or will also invest significant resources and time assisting Employee in developing important business relationships vital to the Company’s business. During Employee’s employment with the Company and for a period of one (1) year following the termination of Employee’s employment with the Company at any time and for any reason, Employee shall not, on Employee’s own behalf or on behalf of others, directly or indirectly (whether as an Employee, consultant, investor, partner, sole proprietor or otherwise), perform services for, become employed by, or become associated with (such as through ownership) any entity which engages in a business which competes with the Employer’s business. The above notwithstanding, the ownership, for investment purposes, of up to one percent (1%) of the total outstanding equity securities of a publicly traded company, shall not be considered a violation of this subparagraph (d).

(e) Enforcement

(i) Employee acknowledges that the restrictions contained in this Agreement including this Paragraph (e) are necessary to protect the Company’s confidential and proprietary information, trade secrets, intellectual property and other legally protectable business information; and further acknowledges and agrees that each and every restriction in this Paragraph (e) is reasonable in all respects, including duration, territory and scope of activity.

(ii) Employee agrees that the restrictions contained in this Agreement including this Paragraph (e) shall be construed as separate agreements independent of any other provision of this Agreement or any other agreement between Employee and the Company. To the extent that any restriction of this Paragraph (e) is determined by any court of competent jurisdiction to be unenforceable, the Parties expressly agree and intend that such restriction be reduced in scope to the extent permitted by law, and that such remaining restriction be enforced, and that the other restrictions of this Paragraph (e) remain in full force and effect.

(iii) Employee agrees that the existence of any claim or cause of action by Employee against the Company shall not constitute a defense to the enforcement by the Company of the covenants and restrictions in this Paragraph (e).

(iv) Employee agrees that the injury the Company will suffer in the event of the breach by Employee of any clause of this Agreement including this Paragraph (e) will cause the Company irreparable injury that cannot be adequately compensated by monetary damages alone. Therefore, Employee agrees that the Company (and each of its affiliates and subsidiaries), without limiting any other legal or equitable remedies available to it, shall be entitled to obtain equitable relief by injunction or otherwise, without the posting of any bond, from any U.S. or non-U.S. agency, court or tribunal of competent jurisdiction, including, without limitation, injunctive relief to prevent the employee’s failure to comply with the terms and conditions of this Paragraph (e). The periods of time referenced in each of subparagraphs (b), (c) and (d) above shall be tolled on a day-for-day basis for each day during which Employee violates the provisions of subparagraphs (b), (c) or (d) in any respect, so that Employee is restricted from engaging in the activities prohibited by subparagraphs (b), (c) and (d) for the full stated time period.

(v) Employee acknowledges that any breach or violation of this Agreement may subject Employee to civil and criminal damages and penalties including, without limitation,

under the Economic Espionage Act and the Defend Trade Secrets Act. An individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made—(i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Accordingly, the Parties to this Agreement have the right to disclose in confidence trade secrets to Federal, State, and local government officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of law. The Parties also have the right to disclose trade secrets in a document filed in a lawsuit or other proceeding, but only if the filing is made under seal and protected from public disclosure. Nothing in this Agreement is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by 18 U.S.C. § 1833(b).

2. Intellectual Property.

(i) Employee will not at any time during or after Employee’s employment with the Company have or claim any right, title or interest in any Inventions, trade name, trademark, patent, invention, trade secret, works of authorship, copyright, work for hire or other similar rights belonging to or used by the Company and shall not have or claim any right, title or interest in any material or matter of any sort prepared for or used in connection with the business or promotion of the Company, whatever Employee’s involvement with such matters may have been, and whether procured, produced, prepared, or published in whole or in part by Employee; it being the intention of the Parties that Employee shall and hereby does, recognize that the Company now has and shall hereafter have and retain the sole and exclusive rights in any and all such Inventions, trade names, trademarks, patents, inventions, trade secrets, works of authorship, and copyrights (all Employee’s work in this regard being a work for hire for the Company under the copyright laws of the United States) and hereby assigns and agrees to assign Employee’s entire worldwide interest in the foregoing exclusively to Company. If any work created by Employee is not a work for hire under the copyright laws of the United States, then Employee hereby assigns to the Company all rights, title and interests in each such work (including, but not limited to, copyrights rights). Employee shall cooperate fully with the Company during Employee’s employment and thereafter in the securing of Inventions, trade name, trademark, patent or copyright protection or other similar rights in the United States and in foreign countries. Employee acknowledges that compensation paid by Company in accordance with its policies and procedures is reasonable and complies with the inventor award and remuneration laws of non-U.S. countries including the Peoples Republic of China and Germany.

(ii) The fact that such copyrightable works, Inventions or other intellectual property are created by Employee outside of the Company’s facilities or other than during Employee’s working hours with the Company shall not diminish the Company’s rights with respect to such works, Inventions or other intellectual property which otherwise fall within this paragraph. Employee agrees to execute and deliver to the Company such further instruments or documents as may be requested by the Company in order to effectuate the purposes of this Agreement.

(iii) Employee shall promptly and fully disclose to the Company, in writing, any inventions, ideas, discoveries, or improvements, whether patentable or unpatentable (referred to herein collectively as “Invention(s)”), of whatever nature conceived by Employee or made in whole or in part by Employee while employed by the Company, and Employee recognizes the

Company’s sole and exclusive proprietary right(s) in any Invention(s) which is/are deemed by its/their nature to have resulted from the present or past duties of Employee within the scope of the Company’s business, whether they are patentable or not. Any inventions, patented or unpatented, which were made or conceived by Employee prior to employment and acknowledged by Company in the Attachment, are excluded from this Agreement.

(iv) Employee also recognizes and agrees that the Company has a sole and exclusive proprietary right in any Invention(s) which was/were developed and/or conceived while directly or indirectly utilizing the Company’s equipment, supplies, and/or facilities during the course of Employee’s performance of duties. Subject to the relevant laws, Employee also recognizes and agrees that the Company’s sole and exclusive proprietary right in any Invention(s) which was/were developed, conceived, and/or reduced to practice, constructively or otherwise, while directly or indirectly utilizing, making use of, incorporating any part of, and/or based in whole or in part on confidential information, during the course of Employee’s performance of duties. To the extent allowable by law, Employee also recognizes and agrees that the Company’s sole and exclusive proprietary right in any Invention(s) which was/were developed and/or conceived while directly or indirectly utilizing the Company’s equipment, supplies, and/or facilities, even after Employee’s employment by the Company has ended, if the Invention relates to: (i) any of the Company’s or its affiliates’ businesses; (ii) to the Company or its affiliates actual or demonstrably anticipated research or development; or (iii) the invention results from any work falling within the scope of Employee’s job duties for the Company.

3. Accounting, Record Keeping and Laboratory Notebooks. Employee agrees to accurately prepare, maintain, and file such proper accounts, books, records and notebooks as directed by Employee’s supervisor. Employee further agrees that the foregoing shall not include any materially false or misleading statements or omit any material facts. Employee further recognizes and agrees that, subject to the relevant laws, all records, data, information, and all records and notebooks kept by Employee during the course of Employee’s employment or which are related to the subject of this Agreement, whether or not directed by Employee’s supervisor, are the property of the Company, including the content thereof as well as any reproductions, copies, and all information derived therefrom, and will be returned to the Company upon termination of Employee’s employment.

4. Execution of Documents, and Testimony.

(i) Employee agrees to give evidence, testify and execute and deliver documents to the Company in order to cooperate fully with the Company in the securing of trade name, trademark, patent or copyright protection or other similar rights in the United States and in foreign countries. Employee agrees that this shall include, without limitation, the execution of any documents necessary or convenient to the Company, its assign(s) and/or designee(s), to obtain domestic or foreign patents, copyrights, and/or trademarks thereon, to the extent the Company, or its assigns or designee, may choose to apply for the same. Employee agrees to execute such documents whether the Company makes its request during or after Employee’s employment with the Company. Documents that employee agrees to execute shall include, without limitation, affidavits, applications, declarations, and assignments.

(ii) Employee further agrees to testify, either personally or through affidavits, in any legal proceedings relating to Invention(s) and Confidential Information, whenever requested by the Company.

(iii) Employee hereby irrevocably appoints the Company as Employee’s attorney-in-fact (with a power coupled with an interest) to execute any and all documents which may be necessary or appropriate in the security of such rights, including but not limited to, any copyright, patent and patent application in Employee’s work.

(iv) The Company shall bear all reasonable third party expenses required for Employee to comply with this Paragraph. Unless otherwise required under any applicable laws, Employee shall not be due any remunerations or payment associated with complying with the terms of this Agreement in addition to or outside of Employee’s salary and monthly allowance. After employment with the Company, in addition to reasonable third party expenses, should Employee be required to personally appear in any legal proceedings where the Company is enforcing its rights after Employee’s employment by the Company has terminated, the Company shall bear all reasonable expenses incurred by Employee as a result of such personal appearance. The Company’s agreement to the foregoing shall not include, and the Company shall not bear, any of Employee’s attorney fees or costs associated with any proceeding in which the Company and Employee are adversaries.

5. Employment at Will. Employee acknowledges and agrees that Employee’s employment with the Company is “at will” employment.

7. Return of Company Property.

Upon the termination of Employee’s employment, and earlier if the Company so requests at any time, Employee shall promptly deliver to the Company (and shall not keep copies in Employee’s possession or deliver to any other person or entity) all of the Company’s equipment or Confidential information (as set out in Paragraph 1(a) above) in your possession. This requirement to return any such Company property shall also be a condition of Employee’s right to keep an amount of money or benefit paid to Employee upon Employee’s termination, if any. Further, the Company has the right to pursue all legal remedies to: (i) achieve the return of Company property; (ii) recoup any money, or value of any benefit, paid to Employee upon Employee’s termination; and (iii) obtain its reasonable attorneys’ fees, costs, or disbursements incurred in the exercise of its legal rights under the Paragraph.
