If your employment is terminated by the Company with Cause at any time prior to or on the first anniversary of the Effective Date, or by you without cause or without Good Reason (as defined in Section 7 below) prior to or on the first anniversary of the Effective Date, you will not be entitled to retain any portion of the Signing Bonus and you will be obligated to immediately repay to the Company the Signing Bonus, in full, on the date of termination. In the event that your employment is terminated by the Company with Cause or by you without cause or without Good Reason: (a) after the first anniversary of the Effective Date, but prior to or on the second anniversary of the Effective Date, the Company will allow you to retain 25% of the unearned bonus, and you hereby agree to repay to the Company, on the date of termination, 75% of the bonus; or (b) after the second anniversary of the Effective Date, but prior to or on the third anniversary of the Effective Date, the Company will allow you to retain 50% of the unearned bonus, and you hereby agree to repay to the Company, on the date of termination, 50% of the bonus; or (c) after the third anniversary of the Effective Date, but prior to or on the fourth anniversary of the Effective Date, the Company will allow you to retain 75% of the unearned bonus, and you hereby agree to repay to the Company, on the date of termination, 25% of the bonus.

For sake of clarity, if your employment terminates due to your disability or death at any time, such termination shall not be subject to the above provisions and you or your estate will be entitled to retain 100% of the bonus. For purposes of this Section 5 only, Cause shall mean (1) your conviction or plea of nolo contender to a misdemeanor involving moral turpitude or any felony, (2) your commission of any act of theft, embezzlement or misappropriation of Company assets, (3) your material breach of any agreement with the Company, (4) your failure to follow the reasonable and lawful written direction of any superior, provided that you are given five days notice and opportunity to cure such failure, if curable, prior to termination, (5) your willful failure to perform the essential duties of your position, or (6) your commission of any act of unlawful discrimination, harassment or retaliation. This does not alter the at-will nature of your employment.

For purposes of Section 409A, your right to receive any installment payments under this offer letter shall be treated as a right to receive a series of separate payments and, accordingly, each such installment payment shall at all times be considered a separate and distinct payment.

PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT

PUMA BIOTECHNOLOGY, INC.

PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT

In consideration of my employment by Puma Biotechnology, Inc. (the “Company”) (the definition of “Company” for the purposes of this Agreement shall include Puma Biotechnology, Inc., its affiliates, and subsidiaries) and access to Proprietary Information (defined below) being given to me by the Company, I hereby agree to this Proprietary Information and Inventions Agreement as of 10/15/2018 (the “Agreement”), as follows:

1. Proprietary Information. The term “Proprietary Information” shall mean all information received by me in the course of my employment by the Company, including without limitation all trade secrets, inventions, confidential knowledge, data or any other information or materials that the Company treats or considers as proprietary, whether or not such Proprietary Information is patentable or copyrightable, however it is embodied and irrespective of whether it is labeled as “proprietary” or “confidential”. By way of illustration but not limitation, “Proprietary Information” includes (a) inventions, trade secrets, know-how, ideas, confidential knowledge, improvements, discoveries, developments, processes, designs, techniques, formulas, formulations, source and object codes, data, programs, trademarks and works of authorship; organisms, plasmids, cosmids, bacteriophages, expression vectors, cells, cell lines, tissues, materials, substrates, media, delivery methods or transfection methods and other biological materials and the progeny and clones of the foregoing biological materials, assays, compounds, peptides, proteins, DNA, RNA, and their constructs, and sequence, amino acid, genomic, and structural information relating thereto; crystals, optically active materials, ceramics, metals, metal oxides and organic and inorganic chemical and other physical materials and derivatives and salt forms of the foregoing (hereinafter the Proprietary Information described in clause (a) shall collectively be referred to as “Inventions”); (b) information regarding the Company’s plans for research, regulatory, development, manufacturing, engineering, marketing and selling efforts, the Company’s business plans and plans for new products, budgets and unpublished financial statements, licenses, contractual arrangements, prices and costs, suppliers, distributors and customers; and information regarding the skills, background and compensation of other employees of the Company and (c) all Third Party Information (as defined in Section 3).

2. Recognition of Company’s Rights; Nondisclosure. I acknowledge that as a result of my responsibilities at the Company, I am likely to be exposed and given access to the Proprietary Information of the Company. I understand and agree that my access to the Proprietary Information is for the sole and exclusive purpose of producing technology and performing other work for the benefit of the Company and that the Company has a substantial ongoing investment in the development and acquisition of such Proprietary Information, which investment would be irreparably and adversely affected if this Agreement were breached. At all times during the term of my employment and thereafter, I will hold the Company’s Proprietary Information in the strictest confidence and will not, except with the written permission of the Chief Executive Officer of the Company, disclose (which term throughout this Agreement includes, but is not limited to, lecturing upon or publishing) any such Proprietary Information to anyone other than Company personnel who need to know such information in connection with their work for the Company or use such Proprietary Information except in connection with any work for the Company.

I further acknowledge that Proprietary Information is solely the property of the Company and I agree that at no time either during the period of my employment nor thereafter will I challenge or engage in any other acts which question or impugn the validity or ownership of the Company’s rights in any Proprietary Information. I further acknowledge that any and all improvements or modifications to Proprietary Information that I generate, make, conceive, develop or reduce to practice or to specific form, whether alone or in conjunction with others, either during or after the period of my employment with the Company shall constitute Proprietary Information.

3. Third Party Information. I understand that the Company has received and in the future will receive from third parties confidential or proprietary information (“Third Party Information”) that is subject to a duty on the 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 treat all Third Party Information as Proprietary Information for purposes of this Agreement.

4. Assignment of Inventions.

(a) Except as provided below in Section 4(b) of this Agreement, I hereby assign to the Company all my right, title and interest in and to any and all Inventions, whether or not patentable or registrable under copyright or similar statutes, that I make, conceive or reduce to practice, reduce to specific form or learn, either alone or jointly with others, in the course of my employment by the Company, whether developed in whole or in part using the Company’s equipment, supplies, facilities, trade secret information or Proprietary Information; or relating at the time of conception or reduction to practice to the Company’s business, or actual or demonstrably anticipated research or development of the Company; or resulting from any work performed by me for the Company (collectively, the “Employment Inventions”). I recognize that this Agreement does not require assignment of any invention which qualifies fully for protection under Section 2870 of the California Labor Code (hereinafter “Section 2870”), which provides as follows:

(i) Any provision in an employment agreement which provides that an employee shall assign, or offer to assign, any of his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own time without using the employer’s equipment, supplies, facilities, or trade secret information, except for those inventions that either:

(1) relate at the time of conception or reduction to practice of the invention to the employer’s business, or actual or demonstrably anticipated research or development of the employer; or

(2) result from any work performed by the employee for the employer.

(ii) To the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise excluded from being required to be assigned under subdivision (a), the provision is against the public policy of California and is unenforceable.

(b) I have set forth on Exhibit A attached hereto, a complete list of all restrictions, express or implied, which would prevent me from complying with all of the requirements of Section 4(a) of this Agreement in whole or in part. If full disclosure of such restrictions, express or implied, in Exhibit A would cause me to violate any prior confidentiality agreement, I understand that I am to describe such restrictions in Exhibit A at the most specific level possible without violating any such restrictions. Exhibit A is incorporated into this Agreement by reference as if fully set forth herein. I will promptly inform the Company in writing of any such restrictions that arise between the time I sign this Agreement and the time my employment with the Company commences.

(c) I also assign to or assign as directed by the Company all my right, title and interest in and to all Employment Inventions, full title to which is required to be in the United States by a contract between the Company and the United States or any of its agencies.

(d) I acknowledge that all original works of authorship which are made by me (solely or jointly with others) within the scope of my employment and which are protectable by copyright are “works made for hire,” as that term is defined in the United States Copyright Act (17 U.S.C., Section 101).

5. Enforcement of Proprietary Rights. To assist the Company in exercising its ownership rights to all Proprietary Information or Employment Inventions that I generate, make, conceive, reduce to practice or to specific form, alter or modify, I will, if requested by the Company, execute, verify and deliver assignments of all rights in the United States and elsewhere, including but not limited to patent and copyright rights, in such Proprietary Information or Employment Inventions to the Company or its designees. I will also assist the Company in every proper way to obtain and from time to time enforce its United States and foreign rights relating to Proprietary Information or Employment Inventions in any and all countries, irrespective of whether I had any role in the development or modification of such Proprietary Information or Employment Inventions. To that end, I will execute, verify and deliver such documents and perform such other acts (including appearances as a witness) as the Company may reasonably request for use in applying for, obtaining, perfecting, evidencing, sustaining and enforcing such proprietary rights and the assignment thereof to the Company. My obligation to assist the Company with respect to all its rights in Proprietary Information or Employment Inventions in any and all countries shall continue beyond the termination of my employment, but the Company shall compensate me at a reasonable rate after my termination for the time actually spent by me at the Company’s request on such assistance.

In the event the Company is unable for any reason, after good faith and all reasonable effort, to secure my signature on any document needed in connection with the actions specified in this Section 5, I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, which appointment is coupled with an interest, to act for and in my behalf to execute, verify and file any such documents and to do all other lawfully permitted acts to further the purposes of the preceding paragraph thereon with the same legal force and effect as if executed by me. I hereby waive and quitclaim to the Company any and all claims, of any nature whatsoever, which I now or may hereafter have for infringement of any proprietary rights assigned hereunder to the Company.

6. Obligation to Keep Company Informed. I will promptly disclose to the Company fully and in writing and will hold in trust for the sole right and benefit of the Company any and all Employment Inventions that I make, conceive, develop or reduce to practice or to specific form, whether alone or in conjunction with others, during or after the period of my employment with the Company. In addition, after any termination of my employment, I will promptly disclose to the Company fully and in writing, the full particulars of all patent applications filed by me which disclose or claim Proprietary Information or Employment Inventions.

I will also promptly disclose to the Company fully and in writing any inventions containing or disclosing Proprietary Information that I believe fully qualify for protection under Section 2870; and I will at that time provide to the Company in writing all evidence necessary to substantiate that belief. I understand that the Company will keep in confidence and will not disclose to third parties without my consent any proprietary information disclosed in writing to the Company pursuant to this Agreement relating to Inventions that qualify fully for protection under the provisions of Section 2870. I will preserve the confidentiality of any Employment Invention that does not fully qualify for protection under Section 2870.

7. Prior Inventions. The term “Prior Inventions” shall mean any and all inventions, trade secrets, know-how, know-how, ideas, confidential knowledge, improvements, discoveries, developments, processes, designs, techniques, formulas, formulations, source and object codes, data, programs, trademarks and works of authorship; organisms, plasmids, cosmids, bacteriophages, expression vectors, cells, cell lines, tissues, materials, substrates, media, delivery methods or transfection methods and other biological materials and the progeny and clones of the foregoing biological materials, assays, compounds, peptides, proteins, DNA, RNA, and their constructs, and sequence, amino acid, genomic, and structural information relating thereto; crystals, optically active materials, ceramics, metals, metal oxides and organic and inorganic chemical and other physical materials and derivatives and salt forms of the foregoing, which I have, alone or jointly with others, conceived, developed or reduced to practice or caused to be conceived, developed or reduced to practice prior to the commencement of my employment with the Company. To preclude any possible uncertainty over what is a Prior Invention, I have set forth on Exhibit B attached hereto a complete list of all Prior Inventions that I consider to be in whole or part my property or the property of third parties, and that I wish to have excluded from the scope of this Agreement. If full disclosure of any such Prior Invention on Exhibit B would cause me to violate any prior confidentiality agreement, I understand that I am to describe such Prior Inventions in Exhibit B at the most specific level possible without violating any such prior confidentiality agreements. Exhibit B is incorporated into this Agreement as if fully set forth herein. I will promptly inform the Company in writing of any Prior Inventions that occur between the time I sign this Agreement and the time my employment with the Company commences.

8. Unauthorized Use or Disclosure. I shall immediately notify my supervisor or any officer of the Company if I learn of any possible unauthorized use or disclosure of Proprietary Information and shall cooperate fully with the Company to enforce the provisions of this Agreement.

9. Authorized Disclosure. Should I be subject to any governmental, administrative or court order or action purporting to require or authorize the disclosure of any Proprietary Information, in whole or in part, I will immediately notify the Company’s legal department and will immediately provide the Company with all documents and other pertinent information in my possession or control to permit the Company to take such steps as it deems necessary in its sole discretion to block or pursue the confidentiality of such disclosure.

10. Additional Activities. I agree that during the period of my employment by the Company I will not, without the Company’s express written consent, engage in any employment or business activity other than for the Company, except as may be provided in any written agreement between me and an authorized officer of the Company with the Company executed as of the same date, and for the period of my employment by the Company and for one (1) year after the date of termination of my employment by the Company, I will not use any Proprietary Information in order to (i) induce any employee of the Company to leave the employ of the Company or (ii) solicit the business of any client or customer of the Company (other than on behalf of the Company) with whom I had contact during the course of my employment with the Company.

11. No Improper Use of Materials. I acknowledge that the Company forbids me to use or disclose any information that is proprietary to any competitor of the Company or to any other third party. Therefore, during my employment by the Company, I will not use or disclose any confidential information or trade secrets, if any, of any former employer or any other person to whom I have an obligation of confidentiality and I will not bring onto the premises of the Company any unpublished documents or any property belonging to any former employer or any other person to whom I have an obligation of confidentiality unless consented to in writing by that former employer or person. To preclude any possible uncertainty, I have set forth on Exhibit C attached hereto, a complete list of all devices, materials, and documents of a former employer or other person or institution to whom I have an obligation of confidentiality that may be used in providing services to the Company pursuant to the express written authorization of my former employer or such other person. I will promptly notify the Company in writing of any devices, materials, and documents that are required to be set forth in Exhibit C that arise between the time I sign this Agreement and the time my employment with the Company commences. Exhibit C is incorporated into this Agreement by reference as if fully set forth herein. In addition, I will not seek nor knowingly use any information from job applicants, Company employees or other third parties, including but not limited to vendors, that is confidential to the present or former employers of such applicants or former employers of the employees or to such third parties.

12. No Conflicting Obligation. I represent that my performance of all the terms of this Agreement and my position as an employee of the Company does not and will not breach any agreement to keep in confidence information acquired by me in confidence or in trust prior to my employment by the Company. I have not entered into, and I agree I will not enter into, any agreement either written or oral in conflict herewith.

13. Return of Company Materials. When I leave the employ of the Company, I will deliver to the Company any and all copies and originals of drawings, notes, memoranda, lab notebooks, specifications, correspondence (including email and quickmail messages), devices, equipment, formulas, documents, molecules, cells, organisms, plasmids, cosmids, bacteriophages, expression vectors, cell lines, peptides, proteins, DNA, RNA, and their constructs and other biological materials, and the progeny and clones of the foregoing biological materials and sequence, amino acid, genomic, and structural information relating thereto; crystals, optically active materials, ceramics, metals, metal oxides and organic and inorganic chemical and other physical materials and derivatives and salt forms of the foregoing, and any other material containing or disclosing any Inventions, Employment Inventions or Proprietary Information. I further agree that any property situated on the Company’s premises and owned by the Company, including disks and other storage media, quickmail, email, voicemail, filing cabinets or other work areas, is subject to inspection by Company personnel at any time with or without notice. Prior to leaving, I will reasonably cooperate with the Company in completing and signing the Company’s documentation for separating staff members.

14. Name and License. I hereby grant to the Company a non-exclusive worldwide license to use my name and likeness on or in connection with any advertising and promotional materials distributed by or on behalf of the Company in any medium while serving as an employee or director of the Company or thereafter, if such materials describe my prior role as employee or director of the Company.

15. Potential Liability. I have been informed and acknowledge that the unauthorized taking of the Company’s trade secrets (a) could result in civil liability under California Civil Code Section 3426, and that, if willful, could result in an award for triple the amount of the Company’s damages and attorneys’ fees; and (b) is a crime under California Penal Code Section 499c(c), punishable by imprisonment for a time not exceeding one year, or by a fine not exceeding five thousand dollars ($5,000), or by both.

16. Legal and Equitable Remedies. Because my services are personal and unique and because I may have access to and become acquainted with the Proprietary Information of the Company, and due to the irreparable injury which would be suffered by the Company as a result of a breach of this Agreement, the Company shall have the right to enforce this Agreement and any of its provisions by injunction, specific performance or other equitable relief, without bond and without prejudice to any other rights and remedies that the Company may have for a breach of this Agreement.

17. Notices. Any notices required or permitted hereunder shall be given to the appropriate party at the address specified below or at such other address as the party shall specify in writing. Such notice shall be deemed given upon personal delivery to the appropriate address or if sent by certified or registered mail, three (3) days after the date of mailing.

18. Employment at Will. I understand and agree that my employment with the Company is at-will. Therefore, my employment can terminate, with or without cause, and with or without notice, at any time, at my option or the Company’s option, and that the Company can terminate or change all other terms and conditions of my employment, with or without cause, and with or without notice, at any time. I understand that the nature of my employment relationship with the Company will be governed by this Section 18 and that this Section 18 constitutes the entire agreement, arrangement and understanding between me and the Company on this subject matter and supersedes any prior or contemporaneous agreement, arrangement, and understanding on this subject matter. This at-will relationship will remain in effect throughout my employment with the Company or any of its subsidiaries or affiliates, unless it is modified by a written agreement signed by both the Company’s President and me which expressly alters it. This at-will relationship may not be modified by any oral or implied agreement, or by any Company policies, practices or patterns or conduct.

Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement.
