For and in consideration of the Severance Benefit, and other good and valuable consideration, I, for and on behalf of myself and my executors, heirs, administrators, representatives, and assigns, hereby agree to release and forever discharge the Company and all of their respective predecessors, successors, affiliates, subsidiaries, investors, directors, shareholders, members, officers, general or limited partners, employees, attorneys, agents, and representatives, and the employee benefit plans in which I am or have been a participant by virtue of my employment with or service to the Company (collectively, the “Company Releasees”), from any and all claims that I have or may have had against the Company Releasees based on any events or circumstances arising or occurring on or prior to the date hereof and arising directly or indirectly out of, relating to, or in any other way involving in any manner whatsoever my executive service to, or employment by, the Company or the termination thereof, including any and all claims arising under federal, state or local laws of the United States of America or under national, provincial or local laws of the Republic of Korea (as well as any applicable foreign jurisdictions) relating to executive service or employment, including claims of wrongful discharge, breach of express or implied contract, fraud, misrepresentation, defamation, intentional infliction of emotional distress, whistleblowing or liability in tort, and claims of any kind that may be brought in any court or administrative agency, and any related claims for attorneys’ fees and costs. I agree further that this Release of Claims may be pleaded as a full defense to any action, suit, arbitration, or other proceeding covered by the terms hereof that is or may be initiated, prosecuted, or maintained by me or my descendants, dependents, heirs, executors, administrators, or assigns. By signing this Release of Claims, I acknowledge that I intend to waive and release all rights known or unknown that I may have against the Company Releasees under these and any other laws.

I acknowledge and agree that as of the date I execute this Release of Claims (the “Release Effective Date”), I have no knowledge of any facts or circumstances that give rise or could give rise to any claims under any of the laws listed in the preceding paragraph and that I have not filed any claim against any of the Company Releasees before any local, state, federal, or foreign agency, court, arbitrator, mediator, arbitration or mediation panel, or other body (each individually a “Proceeding”). I (i) acknowledge that I will not initiate or cause to be initiated on my behalf any Proceeding and will not participate in any Proceeding, in each case, except as required by law, and (ii) waive any right that I may have to benefit in any manner from any relief (whether monetary or otherwise) arising out of any Proceeding. Further, I understand that, by executing this Release of Claims, I will be limiting the availability of certain remedies that I may have against the Company and limiting also my ability to pursue certain claims against the Company Releasees.

5

Notwithstanding the generality of the foregoing, I do not release (i) claims to receive Severance Benefit, including the Separation Payment, in accordance with the Separation Agreement, (ii) claims for indemnification arising under any applicable indemnification obligation of the Company, or (iii) claims that cannot be waived by law.

I understand that nothing in this Agreement will preclude, prohibit or restrict me from (i) participating or cooperating in any investigation conducted by any governmental agency or authority, or (ii) filing a charge of discrimination with any administrative agency or regulatory authority.

Nothing in this Agreement, or any other agreement with the Company, prohibits or is intended in any manner to prohibit, me from (i) reporting a possible violation of federal or other applicable law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the SEC, the U.S. Congress, and any governmental agency Inspector General, or (ii) making other disclosures that are protected under whistleblower provisions of federal law or regulation. This Agreement does not limit my right to receive an award (including, without limitation, a monetary reward) for information provided to the SEC. I do not need the prior authorization of anyone at the Company to make any such reports or disclosures, and I am not required to notify the Company that I have made such reports or disclosures.

Nothing in this Agreement or any other agreement or policy of the Company is intended to interfere with or restrain the immunity provided under 18 U.S.C. §1833(b). I cannot be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made (i) (A) in confidence to federal, state or local government officials, directly or indirectly, or to an attorney, and (B) for the purpose of reporting or investigating a suspected violation of law, (ii) in a complaint or other document filed in a lawsuit or other proceeding, if filed under seal, or (iii) in connection with a lawsuit alleging retaliation for reporting a suspected violation of law, if filed under seal and does not disclose the trade secret, except pursuant to a court order.

I acknowledge that I have been given at least 21 days in which to consider this Release of Claims. I acknowledge further that the Company has advised me to consult with an attorney of my choice before signing this Release of Claims, and I have had sufficient time to consider the terms of this Release of Claims. I represent and acknowledge that if I execute this Release of Claims before 21 days have elapsed, I do so knowingly, voluntarily, and upon the advice and with the approval of my legal counsel (if any), and that I voluntarily waive any remaining consideration period.

I understand that after executing this Release of Claims, I have the right to revoke it within seven days after its execution. I understand that this Release of Claims will not become effective and enforceable unless the seven-day revocation period passes and I do not revoke the Release of Claims in writing. I understand that this Release of Claims may not be revoked after the seven-day revocation period has passed. I understand also that any revocation of this Release of Claims must be made in writing and delivered to the Company at its principal place of business within the seven-day period.

This Release of Claims will become effective, irrevocable, and binding on the eighth day after its execution, so long as I have not timely revoked it as set forth above. I understand and acknowledge that I will not be entitled to payments or benefits under the Separation Agreement unless this Release of Claims is effective on or before the date that is 60 days following the Resignation Date.

I hereby agree to waive any and all claims to re-engagement or re-employment with the Company and affirmatively agree not to seek further employment with the Company.

6

The provisions of this Release of Claims will be binding upon my heirs, executors, administrators, legal representatives, and assigns. If any provision of this Release of Claims will be held by any court of competent jurisdiction to be illegal, void, or unenforceable, such provision will be of no force or effect. The illegality or unenforceability of such provision, however, will have no effect upon and will not impair the enforceability of any other provision of this Release of Claims.

This Release of Claims will be governed in accordance with the laws of the State of Delaware, without reference to the principles of conflicts of law. Any dispute or claim arising out of or relating to this Release of Claims or claim of breach hereof will be brought exclusively in the United States District Court for the District of Delaware to the extent that federal jurisdiction exists, and in the Delaware Chancery Court to the extent that federal jurisdiction does not exist. By execution of this Release of Claims, I am waiving any right to trial by jury in connection with any suit, action, or proceeding under or in connection with this Release of Claims.

7. Independent Contractor; Benefits.

A. Independent Contractor. It is the express intention of the Company and Consultant that Consultant perform the Services as an independent contractor to the Company. Nothing in this Agreement shall in any way be construed to constitute Consultant as an agent, employee or representative of the Company. Without limiting the generality of the foregoing, Consultant is not authorized to bind the Company to any liability or obligation or to represent that Consultant has any such authority. Consultant agrees to furnish (or reimburse the Company for) all tools and materials necessary to accomplish this Agreement and shall incur all expenses associated with performance, except as expressly provided in Schedule A hereto.

B. Benefits. Unless expressly provided in Schedule A hereto, Consultant is not entitled to or eligible for any benefits, including the kinds of benefits that the Company may make available to its employees, such as group insurance, profit-sharing, incentive or retirement benefits. Because Consultant is an independent contractor, the Company will not withhold or make payments for social security, make unemployment insurance or disability insurance contributions, or obtain workers’ compensation insurance on behalf of Consultant, or make or withhold any payments as required by labor or other applicable laws. If, notwithstanding the foregoing, Consultant is reclassified as an employee of the Company, by any governmental or quasi-governmental authority as the result of any administrative or judicial proceeding Consultant agrees that Consultant shall not, as the result of such reclassification, be entitled to or eligible for, on either a prospective or a retrospective basis, any employee benefits under any plans or programs established or maintained by the Company.

C. Reimbursement of Expenses. Subject to this Section 7(C) and Schedule A hereto, Consultant will be reimbursed for all reasonable and appropriately substantiated out-of-pocket expenses incurred by Consultant at the request of the Company, in the course of rendering the Services. All expenses must be pre-approved in writing by the Company.

D. Taxes. The Company shall be entitled to withhold from any amounts payable under this Agreement any federal, local and foreign withholding and other taxes and charges that the Company is required to withhold. Notwithstanding the foregoing, Consultant shall bear any taxes, fees or other charges that any applicable governmental or quasi-governmental authority may impose on Consultant in addition to the amount withheld by the Company in accordance with the preceding sentence. Because Consultant is an independent contractor, the Company will not make payments for any employment-related taxes or benefits.

E. Compliance with Law. Consultant shall have full and sole responsibility for compliance with all applicable laws with respect to Consultant’s self-employment, sole proprietorship or other form of business organization, and with respect to Consultant’s partners, agents, subcontractors and employees, including payment of taxes, social security, worker’s compensation, unemployment and disability insurance coverage requirements and any immigration requirements. Consultant hereby represents and warrants that Consultant and all individuals assisting Consultant in the performance of Services have all required and necessary licenses and certifications required to perform the Services.

F. Certification. Consultant shall provide the Company with certifications and records (including, as appropriate, copies of Consultant’s tax returns, licenses, and certifications) as the Company may request from time to time, during or after the term of this Agreement, to verify that Consultant has complied with this Section 7.

8. Indemnification. Consultant shall indemnify and hold harmless the Company and its affiliates, directors, officers, agents and employees from and against all taxes, losses, damages, liabilities, penalties, costs and expenses, including attorneys’ fees and other legal expenses, arising directly or indirectly from or in connection with (i) any negligent, reckless or intentionally wrongful act of Consultant or Consultant’s assistants, employees or agents, (ii) a determination by a court or agency that Consultant is not an independent contractor, (iii) any breach by Consultant or Consultant’s assistants, employees or agents of any of the covenants contained in this Agreement, (iv) any failure of Consultant to perform the Services in accordance with all applicable laws, rules and regulations, or (v) any violation or claimed violation of a third party’s rights resulting in whole or in part from the Company’s use of the work product of Consultant under this Agreement.

9. Restrictions.

A. Non-Solicitation. From the date of this Agreement until 12 months after the termination of this Agreement (the “Restricted Period”), Consultant shall not, without the Company’s prior written consent, directly or indirectly, solicit or encourage any employee or contractor of the Company or its affiliates to terminate employment with, or cease providing services to, the Company or its affiliates.
