11. Intellectual Property.

(a) Prior Inventions. The Executive hereby acknowledges and agrees that he has made no invention, original work of authorship, development, improvement, and trade secret prior to the commencement of his employment with the Company, that belong solely to the Executive or belong to the Executive jointly with others (subject to the restriction in Section 9(b))(collectively referred to as “Prior Inventions”)), that relate in any way to any of the Company’s and/or its subsidiaries’ actual or proposed businesses, products, services or research and development, and that are not assigned to the Company and/or its subsidiaries herein). If in the course of the Executive’s employment with the Company (whether during the Term or thereafter), he incorporates into any Company’s or its subsidiaries’ products, processes, services or machines, a Prior Invention owned by the Executive or in which he has an interest, then the Company is hereby granted and shall have a non-exclusive, royalty-free, irrevocable, perpetual, worldwide license (with the right to sublicense) to make, have made, copy, modify, make derivative works of, use, sell and otherwise distribute such Prior Invention as part of, or in connection with, such product, process, service or machine.

(b) Assignment of Inventions. The Executive will promptly make full written disclosure to the Board, will hold in trust for the sole right and benefit of the Company, and hereby assigns to the Company or its designee, all his right, title and interest throughout the world in and to any and all inventions, original works of authorship, developments, concepts, know-how, improvements or trade secrets, whether or not patentable or registerable under copyright or similar laws, that he may solely or jointly conceive or develop or reduce to practice, or cause to be developed or reduced to practice, during his employment with the Company (whether during the Term or thereafter) that (i) relate at the time of conception, development or reduction to practice to the actual or demonstrably proposed business or research and development activities of the Company and/or its subsidiaries, (ii) result from or relate to any work performed for the Company and/or its subsidiaries, whether or not during normal business hours or (iii) are developed through the use of Confidential Information (collectively referred to as “Inventions”). The Executive further acknowledges that all Inventions that are made by him (solely or jointly with others) within the scope of and during the period of his employment with the Company and/or its subsidiaries (whether during the Term or thereafter) are “works made for hire” (to the greatest extent permitted by applicable law) and are compensated by his salary, unless regulated otherwise by law.

(c) Maintenance of Invention Records. The Executive will keep and maintain adequate and current written records of all Inventions made by him (solely or jointly with others) during his employment with the Company and/or its subsidiaries (whether during the Term or thereafter). The records may be in the form of notes, sketches, drawings, flow charts, electronic data or recordings, laboratory notebooks or any similar format. The records will be available to and remain the sole property of the Company and its subsidiaries at all times. The Executive will not remove such records from the Company’s or its subsidiaries’ business premises except as expressly permitted by Company policy that may, from time to time, be revised at the sole discretion of the Company.

(d) Further Assistance. The Executive will assist the Company or its designee, at the Company’s expense, in every way to secure the Company’s rights in any Inventions and any copyrights, patents, trademarks, trade secrets, moral rights or other intellectual property rights relating thereto in any and all countries, including without limitation, the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, records and all other instruments that the Company shall deem necessary in order to apply for, obtain, maintain and transfer such rights and in order to assign and convey to the Company, its successors, assigns and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, trademarks, trade secrets, moral rights or other intellectual property rights relating thereto. The Executive acknowledges that his obligation to execute, or cause to be executed, when it is in his power to do so, any such instrument or papers shall continue after the termination of his employment with the Company until the expiration of the last such intellectual property right in any country. If the Company is unable, because of the Executive’s mental or physical incapacity or unavailability for any other reason, to secure his signature to apply for or to pursue any application for any patents or copyright registrations covering Inventions assigned to the Company above, then the Executive hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as his agent and attorney in fact, to act for and in his behalf and stead to execute and file any such applications and to do all other lawfully-permitted acts to further the application for, prosecution, issuance, maintenance or transfer of letters patent or copyright registrations thereon with the same legal force and effect as if originally executed by the Executive. The Executive hereby waives and irrevocably quitclaims to the Company and/or its subsidiaries any and all claims, of any nature whatsoever, that he now or hereafter has for infringement of any and all Inventions assigned to the Company and/or its subsidiaries.

12. No Prior Restrictions. The Executive represents and warrants that his employment with the Company will not violate, or cause him to be in breach of, any obligation or covenant made to any former employer or other third party, and that during the course of his employment with the Company (whether during the Term or thereafter), he will not take any action that would violate or breach any legal obligation that he may have to any former employer or other third party.

13. No Interference with Executives and Customers. The Executive agrees that, during the Executive’s employment with the Company and for a period of 12 months immediately thereafter, the Executive will not, directly or indirectly through another entity, for himself or any other person or entity, (i) induce or solicit, or attempt to induce or solicit, any Executive or independent contractor of the Company or its subsidiaries (or any individual who was employed or engaged by the Company or its subsidiaries during the one-year period immediately before the termination of the Executive’s employment) to leave the employment of, or to cease his or her contracting relationship with, the Company or its subsidiaries, (ii) interfere in any way with the employment relationship between the Company or its subsidiaries or their Executives and independent contractors, (iii) hire or engage any Executive or independent contractor of the Company or its subsidiaries (or any individual who was employed or engaged by the Company or its subsidiaries during the one-year period immediately before the termination of the Executive’s employment) or (iv) induce or attempt to induce any customer, supplier, licensee or other business relation of the Company or its subsidiaries to cease doing business with the Company or its subsidiaries, or in any way interfere with the relationship between any such customer, supplier, licensee or business relation and the Company or its subsidiaries.

14. Non-Disparagement. Both during and after the Executive’s employment with the Company, the Executive will not disparage, portray in a negative light, or take any action that would be harmful to, or lead to unfavorable publicity for, the Company or any of its current or former clients, suppliers, officers, directors, Executives, agents, consultants, contractors, owners, parents, subsidiaries or divisions, whether in public or private, including without limitation, in any and all interviews, oral statements, written materials, electronically-displayed materials and materials or information displayed on Internet-related sites.

15. Equitable Relief. The Executive acknowledges that the remedy at law for his breach of Sections 9, 10, 11, 13 and 14 above will be inadequate, and that the damages flowing from such breach will not be readily susceptible to being measured in monetary terms. Accordingly, upon a violation of any part of such sections, the Company shall be entitled to immediate injunctive relief (or other equitable relief) and may obtain a temporary order restraining any further violation. No bond or other security shall be required in obtaining such equitable relief, and the Executive hereby consents to the issuance of such equitable relief. Nothing in this Section 15 shall be deemed to limit the Company’s remedies at law or in equity for any breach by the Executive of any of the parts of Sections 9, 10, 11, 13 and 14 above which may be pursued or availed of by the Company.

16. Judicial Modification. The Executive acknowledges that it is the intent of the parties hereto that the restrictions contained or referenced in Sections 9, 10, 11, 13 and 14 above be enforced to the fullest extent permissible under the laws of each jurisdiction in which enforcement is sought. If any of the restrictions contained or referenced in such Sections is for any reason held by an arbitrator or court to be excessively broad as to duration, activity, geographical scope or subject, then such restriction shall be construed, judicially modified or “blue penciled” in such jurisdiction so as to thereafter be limited or reduced to the extent required to be enforceable in such jurisdiction under applicable law.

17. Arbitration. Other than actions seeking injunctive relief to enforce the provisions of Sections 9, 10, 11, 13 and 14 above (which actions may be brought by the Company in a court of appropriate jurisdiction), any dispute or controversy between the parties hereto, whether during the Term or thereafter, including without limitation, matters relating to this Agreement, the Executive’s employment with the Company and the cessation thereof, and all matters arising under any federal, state or local statute, rule or regulation or principle of contract law or common law, including but not limited to any and all medical leave statutes, wage-payment statutes, employment discrimination statutes and any other equivalent federal, state or local statute, shall be settled by arbitration administered by the American Arbitration Association (“AAA”) in Washington, D.C. pursuant to the AAA’s National Rules for the Resolution of Employment Disputes (or their equivalent), which arbitration shall be confidential, final and binding to the fullest extent permitted by law. Each party hereto shall be responsible for paying one-half of the cost of the arbitration (including the cost of the arbitrator), and all of the cost of its own attorneys’ fees and costs, incurred under this Section 18, unless otherwise apportioned by the arbitrator in accordance with applicable law.

18. Notices. All notices and other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered and received by the other party, or when sent by recognized overnight courier to the following addresses:

or to such other address as either party hereto will have furnished to the other in writing in accordance with this Section 18, except that such notice of change of address shall be effective only upon receipt.

19. Severability. In the event that any of the provisions of this Agreement, or the application of any such provisions to the Executive or the Company with respect to obligations hereunder, is held to be unlawful or unenforceable by any court or arbitrator, the remaining portions of this Agreement shall remain in full force and effect and shall not be invalidated or impaired in any manner.

20. Waiver. No waiver by any party hereto of the breach of any term or covenant contained in this Agreement, whether by conduct or otherwise, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such breach, or a waiver of any other term or covenant contained in this Agreement.

21. Entire Agreement. This Agreement amends and restates in entirety the prior employment agreement between the Executive and the Company. This Agreement contains the entire agreement between the Executive and the Company with respect to the subject matter of this Agreement, and supersedes any and all prior agreements and understandings, oral or written, between the Executive and the Company with respect to the subject matter of this Agreement, including without limitation that certain Employment Agreement dated as of August 10, 2009 between the Company and the Executive.

22. Amendments. This Agreement may be amended only by an agreement in writing signed by the Executive and an authorized representative of the Company (other than the Executive).

23. Section 409A Provisions

(a) Six-Month Wait for Key Executives Following Separation from Service. To the extent that any amount payable or benefit to be provided under this Agreement or any other agreement between the parties hereto constitutes an amount payable or benefit to be provided under a “nonqualified deferred compensation plan” (as defined in Internal Revenue Code Section 409A (“Section 409A”)) upon a “separation from service” (as defined in Section 409A), including any amount payable under Section 8 above, and to the extent that the Executive is deemed to be a “specified employee” (as that term is defined in Section 409A and pursuant to procedures established by the Company) on the “separation from service” date, then, notwithstanding any other provision in this Agreement or any other agreement to the contrary, such payment or benefit provision will not be made to the Executive during the six-month period immediately following the Executive’s “separation from service” date. Instead, on the first day of the seventh month following such “separation from service" date, all amounts that otherwise would have been paid or provided to the Executive during that six-month period, but were not paid or provided because of this Section 23(a), will be paid or provided to the Executive at such time, with any cash payment to be made in a single lump sum (without any interest with respect to that six-month period). This six-month delay will cease to be applicable if the Executive “separates from service” due to death or if the Executive dies before the six-month period has elapsed.

(b) Section 409A Compliance. While the Company does not guarantee any particular tax treatment, this Agreement is intended to comply with the requirements of Section 409A and the regulations thereunder, including those requirements that delineate when compensation is exempt from Section 409A, and shall be limited, construed and interpreted in accordance with such intent.

24. Successors and Assigns. Because the Executive’s obligations under this Agreement are personal in nature, the Executive’s obligations may only be performed by the Executive and may not be assigned by him. This Agreement is also binding upon the Executive’s successors, heirs, executors, administrators and other legal representatives, and shall inure to the benefit of the Company and its subsidiaries, successors and assigns.

25. Consultation with Counsel. The Executive acknowledges that he has had a full and complete opportunity to consult with counsel of his own choosing concerning the terms, enforceability and implications of this Agreement.

26. No Other Representations. The Executive acknowledges that the Company has made no representations or warranties to the Executive concerning the terms, enforceability or implications of this Agreement other than as reflected in this Agreement.

27. Headings. The titles and headings of sections and subsections contained in this Agreement are included solely for convenience of reference and will not control the meaning or interpretation of any of the provisions of this Agreement.

28. Counterparts. This Agreement may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, and such counterparts shall together constitute but one agreement.

29. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Maryland, without giving effect to its conflict of laws principles.
