EMPLOYEE CONFIDENTIALITY AND INVENTIONS ASSIGNMENT AGREEMENT

1. CONFIDENTIALITY.

1.1 Nondisclosure; Recognition of Company’s Rights. At all times during my employment and thereafter, I will hold in confidence and will not disclose, use, lecture upon, or publish any of Company’s Confidential Information (defined below), except as such use is required in connection with my work for Company, or unless the Chief Executive Officer (the “CEO”) of Company expressly authorizes in writing such disclosure or publication. I will obtain the CEO’s written approval before publishing or submitting for publication any material (written, oral, or otherwise) that relates to my work at Company and/or incorporates any Confidential Information. I hereby assign to Company any rights I have or acquire in any and all Confidential Information and recognize that all Confidential Information shall be the sole and exclusive property of Company and its assigns.

1.2 Confidential Information. The term “Confidential Information” shall mean any and all confidential knowledge, data or information related to Company’s business or its actual or demonstrably anticipated research or development, including without limitation (a) tangible and intangible information relating to compounds, biological materials, cell lines, samples of assay components, media and/or cell lines and procedures and formulations for producing any such assay components, media and/or cell lines, formulations, products, ideas, processes, know-how, inventions, developments, designs, techniques, formulas, works of authorship, methods, developmental or experimental work, clinical data, test data, improvements, discoveries and trade secrets; (b) information regarding products, plans for research and development, marketing and business plans, budgets, financial statements, contracts, prices, suppliers, licensors, licensees and customers; (c) information regarding the skills and compensation of Company’s employees, contractors, and any other service providers of Company; and (d) the existence of any business discussions, negotiations, or agreements between Company and any third party. Confidential Information does not include any publicly available information that was not wrongfully acquired or disseminated.

1.3 Third Party Information. I understand, in addition, that Company has received and in the future will receive from third parties confidential or proprietary information (“Third Party Information”) subject to a duty on Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes. During the term of my employment and thereafter, I will hold Third Party Information in strict confidence and will not disclose to anyone (other than Company personnel who need to know such information in connection with their work for Company) or use, except in connection with my work for Company, Third Party Information, unless expressly authorized by an officer of Company in writing.

1.4 No Improper Use of Information of Prior Employers and Others. I represent that my employment by Company does not and will not breach any agreement with any former employer, including any noncompete agreement or any agreement to keep in confidence information acquired by me in confidence or trust prior to my employment by Company. I further represent that I have not entered into, and will not enter into, any agreement, either written or oral, in conflict herewith. During my employment by Company, I will not improperly use or disclose any confidential information or trade secrets of any former employer or other third party to whom I have an obligation of confidentiality, and I will not bring onto the premises of Company or use any unpublished documents or any property belonging to any former employer or other third party to whom I have an obligation of confidentiality, unless consented to in writing by that former employer or person. I will use in the performance of my duties only information that is generally known and used by persons with training and experience comparable to my own, is common knowledge in the industry or otherwise legally in the public domain, or is otherwise provided or developed by Company.

2. INVENTIONS.

2.1 Inventions and Intellectual Property Rights. As used in this Agreement, the term “Invention” means any inventions (whether or not patentable), ideas, concepts, information, materials, processes, data, programs, know-how, improvements, discoveries, developments, designs, artwork, formulae, other copyrightable works, and techniques and all Intellectual Property Rights therein. The term “Intellectual Property Rights” means all trade secrets, patent rights, copyrights, trademarks and other intellectual property rights recognized by the laws of any jurisdiction or country.

2.2 Prior Inventions. I agree that I will not incorporate, or permit to be incorporated, Prior Inventions (defined below) in any Company Inventions (defined below) without Company’s prior written consent. I have disclosed on Exhibit A a complete list of all Inventions that I have, or I have caused to be, alone or jointly with others, conceived, developed, or reduced to practice prior to the commencement of my employment by Company, in which I have an ownership interest or which I have a license to use, and that I wish to have excluded from the scope of this Agreement (collectively referred to as “Prior Inventions”). If no Prior Inventions are listed in Exhibit A, I warrant that there are no Prior Inventions. If, in the course of my employment with Company, I incorporate a Prior Invention into a Company Invention, I hereby grant Company a non-exclusive, perpetual, fully-paid

and royalty-free, irrevocable and worldwide license, with rights to sublicense through multiple levels of sublicensees, to reproduce, make derivative works of, distribute, publicly perform, and publicly display in any form or medium, whether now known or later developed, make, have made, use, sell, have sold, import, offer for sale, and exercise any and all present or future rights in, such Prior Invention.

2.3 Assignment of Company Inventions. Subject to Section 2.5 titled “Government or Third Party” and except for Prior Inventions listed in Exhibit A and Inventions that I can prove qualify fully under the provisions of California Labor Code section 2870 or Chapter 765 Section 1060/2 of the Illinois Compiled Statutes, as applicable, I hereby assign and agree to assign in the future (when any such Inventions or Intellectual Property Rights are first reduced to practice or first fixed in a tangible medium, as applicable) to Company all my right, title, and interest in and to any and all Inventions (and all Intellectual Property Rights with respect thereto) made, conceived, reduced to practice, or learned by me, either alone or with others, during the period of my employment by Company (“Company Inventions”). Notwithstanding the foregoing, this assignment shall not apply to any Invention which I establish that I have developed entirely on my own time without using Company’s equipment, supplies, facilities or trade secret information, except for those Inventions that either: relate at the time of conception or reduction to practice to Company’s business, or actual or demonstrably anticipated research or development; or result from any work performed by me for Company.

2.4 Obligation to Keep Company Informed. During the period of my employment and for one (1) year thereafter, I will promptly and fully disclose to Company in writing (a) all Inventions authored, conceived, or reduced to practice by me, either alone or with others, including any that might be covered under California Labor Code section 2870 or Chapter 765 Section 1060/2 of the Illinois Compiled Statutes, as applicable, and (b) all patent applications filed by me or in which I am named as an inventor or co-inventor. Unless otherwise noted by me in writing, such disclosure shall not be interpreted to signify that such Inventions or patent applications are the property of Company.

2.5 Government or Third Party. I also agree to assign all my right, title, and interest in and to any particular Company Invention to a third party, including without limitation the United States, as directed by Company.

2.6 Enforcement of Intellectual Property Rights and Assistance. During the period of my employment and thereafter, I will assist Company in every proper way to obtain and enforce United States and foreign Intellectual Property Rights relating to Company Inventions in all countries. In the event Company is unable to secure my signature on any document needed in connection with such purposes, I hereby irrevocably designate and appoint Company and its duly authorized officers and agents as my agent and attorney in fact,

which appointment is coupled with an interest, to act on my behalf to execute and file any such documents and to do all other lawfully permitted acts to further such purposes with the same legal force and effect as if executed by me.

3. RECORDS. I agree to keep and maintain adequate and current records (in the form of notes, sketches, drawings and in any other form that is required by Company) of all Inventions made by me during the period of my employment by Company, which records shall be available to, and remain the sole property of, Company at all times.

4. ADDITIONAL ACTIVITIES. I agree that (a) during the term of my employment by Company, I shall not, directly or indirectly, without the prior written consent of Company, engage in any employment or business activity that is competitive with, or would otherwise conflict with my employment by, Company, and (b) for the period of my employment by Company and for one (l) year thereafter, I will not, either directly or indirectly, solicit or attempt to solicit any employee, independent contractor, or consultant of Company to terminate his, her or its relationship with Company in order to become an employee, consultant, or independent contractor to or for any other person or entity.

5. RETURN OF COMPANY PROPERTY. Upon termination of my employment or upon Company’s request at any other time, I will deliver to Company all of Company’s property, equipment, and documents, together with all copies thereof, and any other material containing or disclosing any Company Inventions, Third Party Information or Confidential Information of Company and certify in writing that I have fully complied with the foregoing obligation. I agree that I will not copy, delete, or alter any information contained upon my Company computer before I return it to Company. I further agree that any property situated on Company’s premises and owned by Company is subject to inspection by Company personnel at any time with or without notice. Prior to leaving, I will cooperate with Company in attending an exit interview and completing and signing Company’s termination statement.

6. NOTIFICATION OF NEW EMPLOYER. In the event that I leave the employ of Company, I hereby consent to the notification of my new employer of my rights and obligations under this Agreement, by Company’s providing a copy of this Agreement or otherwise.

7. GENERAL PROVISIONS.

7.1 Governing Law and Venue. This Agreement and any action related thereto will be governed, controlled, interpreted, and defined by and under the laws of the State of Illinois, without giving effect to any conflicts of laws principles that require the application of the law of a different state. I hereby expressly consent to the personal jurisdiction and venue in the state and federal courts for the county in which Company’s principal place

of business is located for any lawsuit filed there against me by Company arising from or related to this Agreement.

7.2 Severability. If any provision of this Agreement is, for any reason, held to be invalid or unenforceable, the other provisions of this Agreement will be unimpaired and the invalid or unenforceable provision will be deemed modified so that it is valid and enforceable to the maximum extent permitted by law.

7.3 Survival. This Agreement shall survive the termination of my employment and the assignment of this Agreement by Company to any successor-in-interest or other assignee and be binding upon my heirs and legal representatives.

7.4 Employment. I agree and understand that nothing in this Agreement shall confer any right with respect to continuation of employment by Company, nor shall it interfere in any way with my right or Company’s right to terminate my employment at any time, with or without cause and with or without advance notice.

7.5 Notices. Each party must deliver all notices or other communications required or permitted under this Agreement in writing to the other party at the address listed on the signature page, by courier, by certified or registered mail (postage prepaid and return receipt requested), or by a nationally-recognized express mail service. Notice will be effective upon receipt or refusal of delivery. If delivered by certified or registered mail, any such notice will be considered to have been given five (5) business days after it was mailed, as evidenced by the postmark. If delivered by courier or express mail service, any such notice shall be considered to have been given on the delivery date reflected by the courier or express mail service receipt. Each party may change its address for receipt of notice by giving notice of such change to the other party.

7.6 Injunctive Relief. I acknowledge that, because my services are personal and unique and because I will have access to the Confidential Information of Company, any breach of this Agreement by me would cause irreparable injury to Company for which monetary damages would not be an adequate remedy and, therefore, will entitle Company to injunctive relief (including specific performance). The rights and remedies provided to each party in this Agreement are cumulative and in addition to any other rights and remedies available to such party at law or in equity.

7.7 Waiver. Any waiver or failure to enforce any provision of this Agreement on one occasion will not be deemed a waiver of any other provision or of such provision on any other occasion.

7.8 Export. I agree not to export, directly or indirectly, any U.S. technical data acquired from Company or any products utilizing such data, to countries outside the United States, because such export could be in violation of the United States export laws or regulations.

7.9 Entire Agreement. The obligations pursuant to sections of this Agreement titled “Confidentiality” and “Inventions” shall apply to any time during which I was previously employed, or am in the future employed, by Company as an independent contractor if no other agreement governs nondisclosure and assignment of inventions during such period. This Agreement is the final, complete and exclusive agreement of the parties with respect to the subject matters hereof and supersedes and merges all prior communications between us with respect to such matters. No modification of or amendment to this Agreement, or any waiver of any rights under this Agreement, will be effective unless in writing and signed by me and an authorized representative of Company. Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement.
