Following Employee’s death or a termination of Employee’s employment by reason of a Disability, except as set forth in this Section 8(b), Employee shall have no further rights to any compensation or any other benefits under this Agreement.

(i) The Company may terminate Employee’s employment at any time with Just Cause, effective upon Employee’s receipt of written notice of such termination; provided, however, that with respect to any Just Cause termination relying on clause (iv) or (v) of the definition of Just Cause set forth in Section 1(r) hereof, to the extent that such act or acts or failure or failures to act are curable, Employee shall be given not less than ten (10) days’ written

-6-

notice by the Board of the Company’s intention to terminate him for Just Cause, such notice to state in detail the particular act or acts or failure or failures to act that constitute the grounds on which the proposed termination for Just Cause is based, and such termination shall be effective at the expiration of such ten (10) day notice period unless Employee has fully cured such act or acts or failure or failures to act that give rise to Just Cause during such period.

(ii) In the event that the Company terminates Employee’s employment with Just Cause, he shall be entitled only to the Accrued Obligations. Following such termination of Employee’s employment with Just Cause, except as set forth in this Section 8(c)(ii), Employee shall have no further rights to any compensation or any other benefits under this Agreement.

(d) Termination by the Company without Just Cause. The Company may terminate Employee’s employment at any time without Just Cause, effective upon Employee’s receipt of written notice of such termination. In the event that Employee’s employment is terminated by the Company without Just Cause (other than due to death or Disability), Employee shall be entitled to:

(v) In the event that such termination occurs within twelve (12) months following a Change in Control:

(A) accelerated vesting of all of Employee’s stock options and other equity-based awards and continued exercisability of Employee’s stock options in accordance with the terms of the plan document governing such awards; and

-7-

Notwithstanding the foregoing, the payments and benefits described in clauses (ii), (iii), (iv), and (v) above shall immediately terminate, and the Company shall have no further obligations to Employee with respect thereto, in the event that Employee breaches any provision of the Non-Interference Agreement.

During such ten (10) day notice period, the Company shall have a cure right (if curable), and if not cured within such period, Employee’s termination will be effective upon the expiration of such cure period, and Employee shall be entitled to the same payments and benefits as provided in Section 8(d) hereof for a termination by the Company without Just Cause, subject to the same conditions on payment and benefits as described in Section 8(d) hereof. Following such termination of Employee’s employment by Employee with Good Reason, except as set forth in this Section 8(e), Employee shall have no further rights to any compensation or any other benefits under this Agreement. For the avoidance of doubt, Employee’s sole and exclusive remedy upon a termination of employment with Good Reason shall be receipt of the Severance Benefits.

(f) Termination by Employee without Good Reason. Employee may terminate his employment without Good Reason by providing the Company thirty (30) days’ written notice of such termination. In the event of a termination of employment by Employee under this Section 8(f), Employee shall be entitled only to the Accrued Obligations. In the event of termination of Employee’s employment under this Section 8(f), the Company may, in its sole and absolute discretion, by written notice accelerate such date of termination without changing the characterization of such termination as a termination by Employee without Good Reason. Following such termination of Employee’s employment by Employee without Good Reason, except as set forth in this Section 8(f), Employee shall have no further rights to any compensation or any other benefits under this Agreement.

(g) Release. Notwithstanding any provision herein to the contrary, the payment of any amount or provision of any benefit pursuant to subsection (b), (d), or (e) of this Section 8 (other than the Accrued Obligations) (collectively, the “Severance Benefits”) shall be conditioned upon Employee’s execution, delivery to the Company, and non-revocation of the Release of Claims (and the expiration of any revocation period contained in such Release of Claims) within sixty (60) days following the date of Employee’s termination of employment hereunder. If Employee fails to execute the Release of Claims in such a timely manner so as to permit any revocation period to expire prior to the end of such sixty (60) day period, or timely revokes his acceptance of such release following its execution, Employee shall not be entitled to any of the Severance Benefits. Further, to the extent that any of the Severance Benefits constitutes “nonqualified deferred compensation” for purposes of Section 409A of the Code, any payment of any amount or provision of any benefit otherwise scheduled to occur prior to the

-8-

sixtieth (60^th) day following the date of Employee’s termination of employment hereunder, but for the condition on executing the Release of Claims as set forth herein, shall not be made until the first regularly scheduled payroll date following such sixtieth (60^th) day, after which any remaining Severance Benefits shall thereafter be provided to Employee according to the applicable schedule set forth herein. For the avoidance of doubt, in the event of a termination due to Employee’s death or Disability, Employee’s obligations herein to execute and not revoke the Release of Claims may be satisfied on his behalf by his estate or a person having legal power of attorney over his affairs.

Section 10. Representations and Warranties of Employee.

Employee represents and warrants to the Company that —

(a) Employee is entering into this Agreement voluntarily and that his employment hereunder and compliance with the terms and conditions hereof will not conflict with or result in the breach by him of any agreement to which he is a party or by which he may be bound;

(b) Employee has not violated, and in connection with his employment with the Company will not violate, any non-solicitation, non-competition, or other similar covenant or agreement of a prior employer by which he is or may be bound; and

(c) in connection with his employment with the Company, Employee will not use any confidential or proprietary information he may have obtained in connection with employment with any prior employer.

Section 11. Taxes.

The Company may withhold from any payments made under this Agreement all applicable taxes, including but not limited to income, employment, and social insurance taxes, as shall be required by law. Employee acknowledges and represents that the Company has not provided any tax advice to him in connection with this Agreement and that he has been advised by the Company to seek tax advice from his own tax advisors regarding this Agreement and payments that may be made to him pursuant to this Agreement, including specifically, the application of the provisions of Section 409A of the Code to such payments.

Section 12. Set Off; Mitigation.

The Company’s obligation to pay Employee the amounts provided and to make the arrangements provided hereunder shall be subject to set-off, counterclaim, or recoupment of

-9-

amounts owed by Employee to the Company or its affiliates; provided, however, that to the extent any amount so subject to set-off, counterclaim, or recoupment is payable in installments hereunder, such set-off, counterclaim, or recoupment shall not modify the applicable payment date of any installment, and to the extent an obligation cannot be satisfied by reduction of a single installment payment, any portion not satisfied shall remain an outstanding obligation of Employee and shall be applied to the next installment only at such time the installment is otherwise payable pursuant to the specified payment schedule. Employee shall not be required to mitigate the amount of any payment provided pursuant to this Agreement by seeking other employment or otherwise, and except as provided in Section 8(d)(iv) hereof, the amount of any payment provided for pursuant to this Agreement shall not be reduced by any compensation earned as a result of Employee’s other employment or otherwise.

Section 13. Additional Tax Provisions.

(a) Section 409A Provisions. Notwithstanding any provision in this Agreement to the contrary —

(i) Any payment otherwise required to be made hereunder to Employee at any date as a result of the termination of Employee’s employment shall be delayed for such period of time as may be necessary to meet the requirements of Section 409A(a)(2)(B)(i) of the Code (the “Delay Period”). On the first business day following the expiration of the Delay Period, Employee shall be paid, in a single cash lump sum, an amount equal to the aggregate amount of all payments delayed pursuant to the preceding sentence, and any remaining payments not so delayed shall continue to be paid pursuant to the payment schedule set forth herein.

(ii) Each payment in a series of payments hereunder shall be deemed to be a separate payment for purposes of Section 409A of the Code.

(iii) To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made by the Company no later than the last day of the taxable year following the taxable year in which such expense was incurred by Employee, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect.

(iv) While the payments and benefits provided hereunder are intended to be structured in a manner to avoid the implication of any penalty taxes under Section 409A of the Code, in no event whatsoever shall the Company or any of its affiliates be liable for any additional tax, interest, or penalties that may be imposed on Employee as a result of Section 409A of the Code or any damages for failing to comply with Section 409A of the Code (other

-10-

than for withholding obligations or other obligations applicable to employers, if any, under Section 409A of the Code).

(b) Parachute Payment Gross-Up. If any payment, benefit, or distribution of any type to or for the benefit of Employee, whether paid or payable, provided or to be provided, or distributed or distributable pursuant to the terms of this Agreement or otherwise (collectively, the “Parachute Payments”) would subject Employee to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), the Company will make an additional payment to Employee in an amount (the “Gross-Up Payment”) such that, after payment all taxes and any interest or penalties imposed with respect to such taxes (including, without limitation, federal, state, local income, employment, excise and other similar taxes, but excluding any taxes imposed under Section 409A of the Code) (the “Parachute Tax”) on both the Parachute Payments and the Gross-Up Payment, Employee will be in the same position as if no Parachute Tax had been imposed; provided, that in no event may the Gross-Up Payment exceed $2,000,000. Any Gross-Up Payment shall be timely paid by the Company on Employee’s behalf directly to the appropriate taxing authorities when due, but in all events no later than the last day of the calendar year after the calendar year in which the Parachute Tax shall be paid. The determinations with respect to this Section 13(b) shall be made by an independent accounting firm selected by the Company and reasonably acceptable to Employee (the “Accounting Firm”) paid by the Company.

(i) It is possible that, after the determinations and selections made pursuant to Section 13(b), Employee will receive Parachute Payments and Gross-Up Payments that are, in the aggregate, either more or less than the limitations provided in Section 13(b) above (hereafter referred to as an “Excess Payment” or “Underpayment”, respectively). If it is established, pursuant to a final determination of a court or an Internal Revenue Service proceeding that has been finally and conclusively resolved, that an Excess Payment has been made, then Employee shall refund the Excess Payment to the Company promptly on demand, together with an additional payment in an amount equal to the product obtained by multiplying the Excess Payment times the applicable annual federal rate (as determined in and under Section 1274(d) of the Code) times a fraction whose numerator is the number of days elapsed from the date of Employee’s receipt of such Excess Payment through the date of such refund and whose denominator is 365. In the event that it is determined (y) by a court of competent jurisdiction, or (z) by the Accounting Firm upon request by Employee or the Company, that an Underpayment has occurred, the Company shall pay an amount equal to the Underpayment to Employee within ten (10) days of such determination together with an additional payment in an amount equal to the product obtained by multiplying the Underpayment times the applicable annual federal rate (as determined in and under Section 1274(d) of the Code) times a fraction whose numerator is the number of days elapsed from the date of the Underpayment through the date of such payment and whose denominator is 365; provided, that in no event shall the sum of (i) the Gross-Up Payment, and (ii) the additional payment pursuant to this sentence, exceed $2,000,000.

(ii) Any Gross-Up Payment, as determined pursuant to this Section 13(b), shall be paid by the Company and remitted to the relevant tax authorities when such payment is due, provided that in no event shall such payment be made later than the end of your taxable year next following Employee’s taxable year in which the Parachute Tax on a Parachute

-11-

Payment are remitted to the Internal Revenue Service or any other applicable taxing authority or, in the case of amounts relating to a claim described in Section 13(b)(i) that does not result in the remittance of any federal, state, local and foreign income, excise, social security and other taxes, the calendar year in which the claim is finally settled or otherwise resolved.

CONFIDENTIALITY, NON-INTERFERENCE, AND INVENTION ASSIGNMENT AGREEMENT

EXHIBIT A

CONFIDENTIALITY, NON-INTERFERENCE, AND INVENTION ASSIGNMENT AGREEMENT

As a condition of my becoming employed by, or continuing employment with, Clovis Oncology, Inc., a Delaware corporation (the “Company”), and in consideration of my employment with the Company and my receipt of the compensation now and hereafter paid to me by the Company, I agree to the following:

Section 1. Confidential Information.

(a) Company Group Information. I acknowledge that, during the course of my employment, I will have access to information about the Company and its direct and indirect subsidiaries and affiliates (collectively, the “Company Group”) and that my employment with the Company shall bring me into close contact with confidential and proprietary information of the Company Group. In recognition of the foregoing, I agree, at all times during the term of my employment with the Company and for the ten (10) year period following my termination of my employment for any reason, to hold in confidence, and not to use, except for the benefit of the Company Group, or to disclose to any person, firm, corporation, or other entity without written authorization of the Company, any Confidential Information that I obtain or create. I further agree not to make copies of such Confidential Information except as authorized by the Company. I understand that “Confidential Information” means information that the Company Group has developed, acquired, created, compiled, discovered, or owned or will develop, acquire, create, compile, discover, or own, that has value in or to the business of the Company Group that is not generally known and that the Company wishes to maintain as confidential. I understand that Confidential Information includes, but is not limited to, any and all non-public information that relates to the actual or anticipated business and/or products, research, or development of the Company, or to the Company’s technical data, trade secrets, or know-how, including, but not limited to, research, product plans, or other information regarding the Company’s products or services and markets, customer lists, and customers (including, but not limited to, customers of the Company on whom I called or with whom I may become acquainted during the term of my employment), software, developments, inventions, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, finances, and other business information disclosed by the Company either directly or indirectly in writing, orally, or by drawings or inspection of premises, parts, equipment, or other Company property. Notwithstanding the foregoing, Confidential Information shall not include (i) any of the foregoing items that have become publicly and widely known through no unauthorized disclosure by me or others who were under confidentiality obligations as to the item or items involved or (ii) any information that I am required to disclose to, or by, any governmental or judicial authority; provided, however, that in such event I will give the Company prompt written notice thereof so that the Company Group may seek an appropriate protective order and/or waive in writing compliance with the confidentiality provisions of this Confidentiality, Non-Interference, and Invention Assignment Agreement (the “Non-Interference Agreement”).

(b) Former Employer Information. I represent that my performance of all of the terms of this Non-Interference Agreement as an employee of the Company has not breached and will not breach any agreement to keep in confidence proprietary information,

knowledge, or data acquired by me in confidence or trust prior or subsequent to the commencement of my employment with the Company, and I will not disclose to any member of the Company Group, or induce any member of the Company Group to use, any developments, or confidential or proprietary information or material I may have obtained in connection with employment with any prior employer in violation of a confidentiality agreement, nondisclosure agreement, or similar agreement with such prior employer.

Section 2. Developments.

(a) Developments Retained and Licensed. I have attached hereto, as Schedule A, a list describing with particularity all developments, original works of authorship, developments, improvements, and trade secrets that I can demonstrate were created or owned by me prior to the commencement of my employment (collectively referred to as “Prior Developments”), which belong solely to me or belong to me jointly with another, that relate in any way to any of the actual or proposed businesses, products, or research and development of any member of the Company Group, and that are not assigned to the Company hereunder, or if no such list is attached, I represent that there are no such Prior Developments. If, during any period during which I perform or performed services for the Company Group both before or after the date hereof (the “Assignment Period”), whether as an officer, employee, director, independent contractor, consultant, or agent, or in any other capacity, I incorporate (or have incorporated) into a Company Group product or process a Prior Development owned by me or in which I have an interest, I hereby grant the Company, and the Company Group shall have, a non-exclusive, royalty-free, irrevocable, perpetual, transferable worldwide license (with the right to sublicense) to make, have made, copy, modify, make derivative works of, use, sell, and otherwise distribute such Prior Development as part of or in connection with such product or process.

(b) Assignment of Developments. I agree that I will, without additional compensation, promptly make full written disclosure to the Company, and will hold in trust for the sole right and benefit of the Company all developments, original works of authorship, inventions, concepts, know-how, improvements, trade secrets, and similar proprietary rights, whether or not patentable or registrable under copyright or similar laws, which I may solely or jointly conceive or develop or reduce to practice, or have solely or jointly conceived or developed or reduced to practice, or have caused or may cause to be conceived or developed or reduced to practice, during the Assignment Period, whether or not during regular working hours, provided they either (i) relate at the time of conception, development or reduction to practice to the business of any member of the Company Group, or the actual or anticipated research or development of any member of the Company Group; (ii) result from or relate to any work performed for any member of the Company Group; or (iii) are developed through the use of equipment, supplies, or facilities of any member of the Company Group, or any Confidential Information, or in consultation with personnel of any member of the Company Group (collectively referred to as “Developments”). I further acknowledge that all Developments made by me (solely or jointly with others) within the scope of and during the Assignment Period are “works made for hire” (to the greatest extent permitted by applicable law) for which I am, in part, compensated by my salary, unless regulated otherwise by law, but that, in the event any such Development is deemed not to be a work made for hire, I hereby assign to the Company, or

its designee, all my right, title, and interest throughout the world in and to any such Development.

(c) Maintenance of Records. I agree to keep and maintain adequate and current written records of all Developments made by me (solely or jointly with others) during the Assignment Period. The records may be in the form of notes, sketches, drawings, flow charts, electronic data or recordings, and any other format. The records will be available to and remain the sole property of the Company Group at all times. I agree not to remove such records from the Company’s place of business except as expressly permitted by Company Group policy, which may, from time to time, be revised at the sole election of the Company Group for the purpose of furthering the business of the Company Group.

(d) Intellectual Property Rights. I agree to assist the Company, or its designee, at the Company’s expense, in every way to secure the rights of the Company Group in the Developments and any copyrights, patents, trademarks, service marks, database rights, domain names, mask work rights, moral rights, and other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, recordations, 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 Group the sole and exclusive right, title, and interest in and to such Developments, and any intellectual property and other proprietary rights relating thereto. I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall continue after the Assignment Period until the expiration of the last such intellectual property right to expire in any country of the world; provided, however, the Company shall reimburse me for my reasonable expenses incurred in connection with carrying out the foregoing obligation. If the Company is unable because of my mental or physical incapacity or unavailability for any other reason to secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Developments or original works of authorship assigned to the Company as above, then I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact to act for and in my behalf and stead to execute and file any such applications or records and to do all other lawfully permitted acts to further the application for, prosecution, issuance, maintenance, and transfer of letters patent or registrations thereon with the same legal force and effect as if originally executed by me. I hereby waive and irrevocably quitclaim to the Company any and all claims, of any nature whatsoever, that I now or hereafter have for past, present, or future infringement of any and all proprietary rights assigned to the Company.

Section 3. Returning Company Group Documents.

I agree that, at the time of termination of my employment with the Company for any reason, I will deliver to the Company (and will not keep in my possession, recreate, or deliver to anyone else) any and all Confidential Information and all other documents, materials, information, and property developed by me pursuant to my employment or otherwise belonging to the Company. I agree further that any property situated on the Company’s premises and owned by the Company (or any other member of the Company Group), including disks and other

storage media, filing cabinets, and other work areas, is subject to inspection by personnel of any member of the Company Group at any time with or without notice.

Section 4. Disclosure of Agreement.

As long as it remains in effect, I will disclose the existence of this Non-Interference Agreement to any prospective employer, partner, co-venturer, investor, or lender prior to entering into an employment, partnership, or other business relationship with such person or entity.

Section 5. Restrictions on Interfering.

(a) Non-Competition. During the period of my employment with the Company (the “Employment Period”) and the Post-Termination Non-Compete Period, I shall not, directly or indirectly, individually or on behalf of any person, company, enterprise, or entity, or as a sole proprietor, partner, stockholder, director, officer, principal, agent, or executive, or in any other capacity or relationship, engage in any Competitive Activities in any jurisdiction in which the Company Group is engaged in (or has demonstrable plans to commence) business activities..

(b) Non-Interference. During the Employment Period and the Post-Termination Non-Interference Period, I shall not, directly or indirectly for my own account or for the account of any other individual or entity, engage in Interfering Activities.

(i) “Business Relation” shall mean any current or prospective client, customer, licensee, or other business relation of the Company Group, or any such relation that was a client, customer, licensee, supplier, or other business relation within the six (6) month period prior to the expiration of the Employment Period, in each case, to whom I provided services, or with whom I transacted business, or whose identity became known to me in connection with my relationship with or employment by the Company.

(ii) “Competitive Activities” shall mean any business activity that is competitive with the then-current or demonstrably planned business activities of the Company Group.

(iii) “Interfering Activities” shall mean (A) encouraging, soliciting, or inducing, or in any manner attempting to encourage, solicit, or induce, any Person employed by, or providing consulting services to, any member of the Company Group to terminate such Person’s employment or services (or in the case of a consultant, materially reducing such services) with the Company Group; (B) hiring any individual who was employed by the Company Group within the six (6) month period prior to the date of such hiring and with whom I had contact with during the Employment Period within the six (6) month period prior to the date of such hiring; or (C) encouraging, soliciting, or inducing, or in any manner attempting to encourage, solicit, or induce, any Business Relation to cease doing business with or reduce the amount of business

conducted with the Company Group, or in any way interfering with the relationship between any such Business Relation and the Company Group.

(iv) “Person” shall mean any individual, corporation, partnership, limited liability company, joint venture, association, joint-stock company, trust (charitable or non-charitable), unincorporated organization, or other form of business entity.

(v) “Post-Termination Non-Compete Period” shall mean the period commencing on the date of the termination of the Employment Period for any reason and ending on the six (6) month anniversary of such date of termination.

(vi) “Post-Termination Non-Interference Period” shall mean the period commencing on the date of the termination of the Employment Period for any reason and ending on the twelve (12) month anniversary of such date of termination.

(d) Non-Disparagement. I agree that during the Employment Period, and at all times thereafter, I will not make any disparaging or defamatory comments regarding any member of the Company Group or its respective current or former directors, officers, or employees in any respect or make any comments concerning any aspect of my relationship with any member of the Company Group or any conduct or events which precipitated any termination of my employment from any member of the Company Group. However, my obligations under this subparagraph (d) shall not apply to disclosures required by applicable law, regulation, or order of a court or governmental agency.

Section 6. Reasonableness of Restrictions.

I acknowledge and recognize the highly competitive nature of the Company’s business, that access to Confidential Information renders me special and unique within the Company’s industry, and that I will have the opportunity to develop substantial relationships with existing and prospective clients, accounts, customers, consultants, contractors, investors, and strategic partners of the Company Group during the course of and as a result of my employment with the Company. In light of the foregoing, I recognize and acknowledge that the restrictions and limitations set forth in this Non-Interference Agreement are reasonable and valid in geographical and temporal scope and in all other respects and are essential to protect the value of the business and assets of the Company Group. I acknowledge further that the restrictions and limitations set forth in this Non-Interference Agreement will not materially interfere with my ability to earn a living following the termination of my employment with the Company and that my ability to earn a livelihood without violating such restrictions is a material condition to my employment with the Company.

Section 7. Independence; Severability; Blue Pencil.

Each of the rights enumerated in this Non-Interference Agreement shall be independent of the others and shall be in addition to and not in lieu of any other rights and remedies available to the Company Group at law or in equity. If any of the provisions of this Non-Interference Agreement or any part of any of them is hereafter construed or adjudicated to be invalid or unenforceable, the same shall not affect the remainder of this Non-Interference

Agreement, which shall be given full effect without regard to the invalid portions. If any of the covenants contained herein are held to be invalid or unenforceable because of the duration of such provisions or the area or scope covered thereby, I agree that the court making such determination shall have the power to reduce the duration, scope, and/or area of such provision to the maximum and/or broadest duration, scope, and/or area permissible by law, and in its reduced form said provision shall then be enforceable.

Section 8. Injunctive Relief.

I expressly acknowledge that any breach or threatened breach of any of the terms and/or conditions set forth in this Non-Interference Agreement may result in substantial, continuing, and irreparable injury to the members of the Company Group. Therefore, I hereby agree that, in addition to any other remedy that may be available to the Company, any member of the Company Group shall be entitled to seek injunctive relief, specific performance, or other equitable relief by a court of appropriate jurisdiction in the event of any breach or threatened breach of the terms of this Non-Interference Agreement without the necessity of proving irreparable harm or injury as a result of such breach or threatened breach. Notwithstanding any other provision to the contrary, I acknowledge and agree that the Post-Termination Non-Compete Period, or Post-Termination Non-Interference Period, as applicable, shall be tolled during any period of violation of any of the covenants in Section 5 hereof and during any other period required for litigation during which the Company or any other member of the Company Group seeks to enforce such covenants against me if it is ultimately determined that I was in breach of such covenants.

Section 9. Cooperation.

I agree that, following any termination of my employment, I will continue to provide reasonable cooperation to the Company and/or any other member of the Company Group and its or their respective counsel in connection with any investigation, administrative proceeding, or litigation relating to any matter that occurred during my employment in which I was involved or of which I have knowledge. As a condition of such cooperation, the Company shall reimburse me for reasonable out-of-pocket expenses incurred at the request of the Company with respect to my compliance with this paragraph. I also agree that, in the event that I am subpoenaed by any person or entity (including, but not limited to, any government agency) to give testimony or provide documents (in a deposition, court proceeding, or otherwise) that in any way relates to my employment by the Company and/or any other member of the Company Group, I will give prompt notice of such request to the Company and will make no disclosure until the Company and/or the other member of the Company Group has had a reasonable opportunity to contest the right of the requesting person or entity to such disclosure.

Section 10. General Provisions.

(a) Governing Law and Jurisdiction. EXCEPT WHERE PREEMPTED BY FEDERAL LAW, THE VALIDITY, INTERPRETATION, CONSTRUCTION, AND PERFORMANCE OF THIS NON-INTERFERENCE AGREEMENT IS GOVERNED BY AND IS TO BE CONSTRUED UNDER THE LAWS OF THE STATE OF COLORADO APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN

No modification or amendment to this Non-Interference Agreement, nor any waiver of any rights under this Non-Interference Agreement, will be effective unless in writing signed by the party to be charged. Any subsequent change or changes in my duties, obligations, rights, or compensation will not affect the validity or scope of this Non-Interference Agreement.

This Non-Interference Agreement will be binding upon my heirs, executors, administrators, and other legal representatives and will be for the benefit of the Company, its successors, and its assigns.

As used in this Release of Claims (this “Release”), the term “claims” will include all claims, covenants, warranties, promises, undertakings, actions, suits, causes of action, obligations, debts, accounts, attorneys’ fees, judgments, losses, and liabilities, of whatsoever kind or nature, in law, in equity, or otherwise.

For and in consideration of the Severance Benefits (as defined in my Employment Agreement, dated August 24, 2011, with Clovis Oncology, Inc. (my “Employment Agreement”)), and other good and valuable consideration, I, Xxxx X. Xxxx, for and on behalf of myself and my heirs, administrators, executors, and assigns, effective as of the date on which this release becomes effective pursuant to its terms, do fully and forever release, remise, and discharge the Company and each of its direct and indirect subsidiaries and affiliates, and its successors and assigns, together with its officers, directors, partners, shareholders, employees, and agents (collectively, the “Group”), from any and all claims whatsoever up to the date hereof that I had, may have had, or now have against the Group, whether known or unknown, for or by reason of any matter, cause, or thing whatsoever, including any claim arising out of or attributable to my employment or the termination of my employment with the Company, whether for tort, breach of express or implied employment contract, intentional infliction of emotional distress, wrongful termination, unjust dismissal, defamation, libel, or slander, or under any federal, state, or local law dealing with discrimination based on age, race, sex, national origin, handicap, religion, disability, or sexual orientation. This release of claims includes, but is not limited to, all claims arising under the Age Discrimination in Employment Act (“ADEA”), Title VII of the Civil Rights Act, the Americans with Disabilities Act, the Civil Rights Act of 1991, the Family Medical Leave Act, and the Equal Pay Act, each as may be amended from time to time, and all other federal, state, and local laws, the common law, and any other purported restriction on an employer’s right to terminate the employment of employees. The release contained herein is intended to be a general release of any and all claims to the fullest extent permissible by law.

I acknowledge and agree that as of the date I execute this Release, 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.

By executing this Release, I specifically release all claims relating to my employment and its termination under ADEA, a United States federal statute that, among other things, prohibits discrimination on the basis of age in employment and employee benefit plans.

Notwithstanding any provision of this Release to the contrary, by executing this Release, I am not releasing (i) any claims relating to my rights under Section 8 of my Employment Agreement, (ii) any claims that cannot be waived by law, or (iii) my right of indemnification as provided by, and in accordance with the terms of, the Company’s by-laws or a Company insurance policy providing such coverage, as any of such may be amended from time to time.

-1-

I expressly acknowledge and agree that I —

	•		Am able to read the language, and understand the meaning and effect, of this Release;

	•		Have no physical or mental impairment of any kind that has interfered with my ability to read and understand the meaning of this Release or its terms, and that I am not acting under the influence of any medication, drug, or chemical of any type in entering into this Release;

	•		Am specifically agreeing to the terms of the release contained in this Release because the Company has agreed to pay me the Severance Benefits in consideration for my agreement to accept it in full settlement of all possible claims I might have or ever have had, and because of my execution of this Release;

	•		Acknowledge that, but for my execution of this Release, I would not be entitled to the Severance Benefits;

	•		Understand that, by entering into this Release, I do not waive rights or claims under ADEA that may arise after the date I execute this Release;

	•		Had or could have had [twenty-one (21)][forty-five (45)]¹ days from the date of my termination of employment (the “Release Expiration Date”) in which to review and consider this Release, and that if I execute this Release prior to the Release Expiration Date, I have voluntarily and knowingly waived the remainder of the review period;

	•		Have not relied upon any representation or statement not set forth in this Release or my Employment Agreement made by the Company or any of its representatives;

	•		Was advised to consult with my attorney regarding the terms and effect of this Release; and

	•		Have signed this Release knowingly and voluntarily.

I represent and warrant that I have not previously filed, and to the maximum extent permitted by law agree that I will not file, a complaint, charge, or lawsuit against any member of the Group regarding any of the claims released herein. If, notwithstanding this representation and warranty, I have filed or file such a complaint, charge, or lawsuit, I agree that I shall cause such complaint, charge, or lawsuit to be dismissed with prejudice and shall pay any and all costs required in obtaining dismissal of such complaint, charge, or lawsuit, including without limitation the attorneys’ fees of any member of the Group against whom I have filed


1		To be selected based on whether applicable termination was “in connection with an exit incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967).

-2-

such a complaint, charge, or lawsuit. This paragraph shall not apply, however, to a claim of age discrimination under ADEA or to any non-waivable right to file a charge with the United States Equal Employment Opportunity Commission (the “EEOC”); provided, however, that if the EEOC were to pursue any claims relating to my employment with Company, I agree that I shall not be entitled to recover any monetary damages or any other remedies or benefits as a result and that this Release and Section 8 of my Employment Agreement will control as the exclusive remedy and full settlement of all such claims by me.

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

Notwithstanding anything contained herein to the contrary, this Release will not become effective or enforceable prior to the expiration of the period of seven (7) calendar days following the date of its execution by me (the “Revocation Period”), during which time I may revoke my acceptance of this Release by notifying the Company and the Board of Directors of the Company, in writing, delivered to the Company at its principal executive office, marked for the attention of its Chief Executive Officer. To be effective, such revocation must be received by the Company no later than 11:59 p.m. on the seventh (7^th) calendar day following the execution of this Release. Provided that the Release is executed and I do not revoke it during the Revocation Period, the eighth (8^th) day following the date on which this Release is executed shall be its effective date. I acknowledge and agree that if I revoke this Release during the Revocation Period, this Release will be null and void and of no effect, and neither the Company nor any other member of the Company Group will have any obligations to pay me the Severance Benefits.

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

EXCEPT WHERE PREEMPTED BY FEDERAL LAW, THE VALIDITY, INTERPRETATION, CONSTRUCTION, AND PERFORMANCE OF THIS RELEASE IS GOVERNED BY AND IS TO BE CONSTRUED UNDER THE LAWS OF THE STATE OF COLORADO APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THAT STATE, WITHOUT REGARD TO CONFLICT OF LAWS RULES.
