Compensation Committee and communicated to Employee. The Annual Bonus shall be paid to Employee at the same time as annual bonuses are generally payable to other senior executives of the Company subject to Employee’s continuous employment
through the payment date. 
 Section 5. Employee Benefits. 

During the Term, Employee shall be entitled to participate in health, insurance, retirement, and other benefits provided generally to
similarly situated employees of the Company. Employee shall also be entitled to the same number of holidays, vacation days, and sick days, as well as any other benefits, in each case as are generally allowed to similarly situated employees of the

Section 7. Reimbursement of Business Expenses. 

During the Term, the Company shall pay (or promptly reimburse Employee) for documented, out-of-pocket expenses reasonably incurred by Employee
in the course of performing his duties and responsibilities hereunder, which are consistent with the Company’s policies in effect from time to time with respect to business expenses, subject to the Company’s requirements with respect to
reporting of such expenses.

 Section 8. Termination of Employment. 

(a) General. The Term shall terminate upon the earliest to occur of (i) Employee’s death, (ii) a termination by reason
of a Disability, (iii) a termination by the Company with or without Just Cause, and (iv) a termination by Employee with or without Good Reason. Upon any termination of Employee’s employment for any reason, except as may otherwise be
requested by the Company in writing and agreed upon in writing by Employee, Employee shall be deemed to have resigned from any and all directorships, committee memberships, and any other positions Employee holds with the Company or any other member
of the Company Group and hereby agrees to execute any documents that the Company (or any member of the Company Group) determines necessary to effectuate such resignations. Notwithstanding anything herein to the contrary, the payment (or commencement
of a series of payments) hereunder of any nonqualified deferred compensation (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as Employee has also undergone a “separation
from service” as defined in Treas. Reg. 1.409A-1(h), at which time such nonqualified deferred compensation (calculated as of the date of Employee’s termination of employment hereunder) shall be paid (or commence to be paid) to
Employee on the schedule set forth in this Section 8 as if Employee had undergone such termination of employment (under the same circumstances) on the date of his ultimate “separation from service.” 

(b) Termination Due to Death or Disability. Employee’s employment shall terminate automatically upon his death. The Company may
terminate Employee’s employment immediately upon the occurrence of a Disability, such termination to be effective upon Employee’s receipt of written notice of such termination. Upon Employee’s death or in the event that
Employee’s employment is terminated due to his Disability, Employee or his estate or his beneficiaries, as the case may be, shall be entitled to: 

(i) The Accrued Obligations; and 

(ii) Any unpaid Annual Bonus in respect of any completed fiscal year that has ended prior to the date of such termination, which amount shall
be paid at such time annual bonuses are paid to other senior executives of the Company, but in no event later than the date that is 2 1⁄2 months following the
last day of the fiscal year in which such termination occurred. 
 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. 

(c) Termination by the Company with Just Cause. 

(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: 
 (i) The Accrued Obligations; 

(ii) Any unpaid Annual Bonus in respect of any completed fiscal year that has ended prior to the date of such termination, which amount shall
be paid at such time annual bonuses are paid to other senior executives of the Company, but in no event later than the date that is 2 1⁄2 months following the
last day of the fiscal year in which such termination occurred; 
 (iii) Continued payment of Base Salary during the Severance Term,
payable in accordance with the Company’s regular payroll practices; 
 (iv) Subject to Employee’s election of COBRA continuation
coverage under the Company’s group health plan, on the first regularly scheduled payroll date of each month of the Severance Term, the Company will pay Employee an amount equal to the “applicable percentage” of the monthly COBRA
premium cost (which, for purposes hereof, shall be the percentage of Employee’s health care premium costs covered by the Company as of the date of termination); provided, that the payments pursuant to this clause (iv) shall cease
earlier than the expiration of the Severance Term in the event that Employee becomes eligible to receive any health benefits, including through a spouse’s employer, during the Severance Term; and 

(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 
 (B) an amount equal to the Target Bonus,
payable in substantially equal monthly installments during the Severance Term. 

  
 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. Following such termination of
Employee’s employment by the Company without Just Cause, except as set forth in this Section 8(d), 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 by the Company without Just Cause shall be receipt of the Severance Benefits. 

(e) Termination by Employee with Good Reason. Employee may terminate his employment with Good Reason by providing the Company ten
(10) days’ written notice setting forth in reasonable specificity the event that constitutes Good Reason, which written notice, to be effective, must be provided to the Company within sixty (60) days of the occurrence of such event.
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 (60th) 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 (60th) 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 9. Non-Interference Agreement. 

As a condition of, and prior to commencement of, Employee’s employment with the Company, Employee shall have executed and delivered to
the Company the Non-Interference Agreement. The parties hereto acknowledge and agree that this Agreement and the Non-Interference Agreement shall be considered separate contracts, and the Non-Interference Agreement will survive the termination of
this Agreement for any reason. 
 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 than for withholding obligations or other obligations applicable to employers, if any, under Section 409A of the Code). 

  
 10 

 (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. 

Section 14. Successors and Assigns; No Third-Party Beneficiaries. 

(a) The Company. This Agreement shall inure to the benefit of the Company and its respective successors and assigns. Neither this
Agreement nor any of the rights, obligations, or interests arising hereunder may be assigned by the Company to a Person (other than another member of the Company Group, or its or their respective successors) without Employee’s prior written
consent (which shall not be unreasonably withheld, delayed, or conditioned); provided, however, that in the event of a sale of all or substantially all of the assets of the Company or any direct or indirect division or subsidiary
thereof to which the Employee’s employment primarily relates, the Company may provide that this Agreement will be assigned to, and assumed by, the acquiror of such assets, it being agreed that in such circumstances, Employee’s consent will
not be required in connection therewith. 
 (b) Employee. Employee’s rights and obligations under this Agreement shall not be
transferable by Employee by assignment or otherwise, without the prior written consent of the Company; provided, however, that if Employee shall die, all amounts then payable to Employee hereunder shall be paid in accordance with the
terms of this Agreement to Employee’s devisee, legatee, or other designee, or if there be no such designee, to Employee’s estate. 

(c) No Third-Party Beneficiaries. Except as otherwise set forth in Section 8(b) or Section 14(b) hereof, nothing expressed or
referred to in this Agreement will be construed to give any Person other than the Company, the other members of the Company Group, and Employee any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision
of this Agreement. 
 Section 15. Waiver and Amendments. 

Any waiver, alteration, amendment, or modification of any of the terms of this Agreement shall be valid only if made in writing and signed by
each of the parties hereto; provided, however, that any such waiver, alteration, amendment, or modification must be consented to on the Company’s behalf by the Board. No waiver by either of the parties hereto of their rights

 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 

  
 A-1 

 
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. 

(c) Whistleblower; Defend Trade Secrets Act Disclosure. 

(i) In addition, I understand that nothing in this Agreement shall be construed to prohibit me from reporting possible violations of law or
regulation to any governmental agency or regulatory body or making other disclosures that are protected under any law or regulation, or from filing a charge with or participating in any investigation or proceeding conducted by any governmental
agency or regulatory body. 
 (ii) I understand that the Defend Trade Secrets Act provides that I may not be held criminally or civilly
liable under any Federal or state trade secret law for the disclosure of a trade secret that is made in confidence to a Federal, state, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of
reporting or investigating a suspected violation of law; or that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. In the event that I file a lawsuit for retaliation by any
member of the Company Group for reporting a suspected violation of law, I may disclose the trade secret to my attorney and use the trade secret information in the court proceeding, if I file any document containing the trade secret under seal and do
not disclose the trade secret, except pursuant to court order. 
 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. 

  
 A-2 

 (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 

  
 A-3 

 
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. 
 (c)
Definitions. For purposes of this Non-Interference Agreement : 
 (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

  
 A-4 

 
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

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 

  
 A-5 

 
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 

  
 A-6 

 
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 THAT STATE, WITHOUT REGARD TO CONFLICT OF LAWS RULES. FURTHER, I HEREBY WAIVE ANY
RIGHT TO TRIAL BY JURY IN CONNECTION WITH ANY SUIT, ACTION, OR PROCEEDING UNDER OR IN CONNECTION WITH THIS NON-INTERFERENCE AGREEMENT. 

(b) Entire Agreement. This Non-Interference Agreement sets forth the entire agreement and understanding between the Company and me
relating to the subject matter herein and merges all prior discussions between us. 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. 

(c) No Right of Continued Employment. I acknowledge and agree that nothing contained herein shall be construed as granting me any right
to continued employment by the Company, and the right of the Company to terminate my employment at any time and for any reason, with or without cause, is specifically reserved. 

(d) Successors and Assigns. 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. I expressly acknowledge and agree that this Non-Interference Agreement may be assigned by the Company without my consent to any other member of the Company
Group as well as any purchaser of all or substantially all of the assets or stock of the Company, whether by purchase, merger, or other similar corporate transaction, provided that the license granted pursuant to Section 2(a) may be assigned to
any third party by the Company without my consent. 
 (e) Survival. The provisions of this Non-Interference Agreement shall survive
the termination of my employment with the Company and/or the assignment of this Non-Interference Agreement by the Company to any successor in interest or other assignee.

RELEASE OF CLAIMS 

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 July 6, 2017, with Clovis Oncology, Inc.
(my “Employment Agreement”)), and other good and valuable consideration, I, Daniel Muehl, 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. The release of claims in this Release 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. 
 I expressly acknowledge and agree that I
– 

  
 B-1 

	 	•	 	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

employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967). 

  
 B-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 Group and affirmatively agree not to
seek further employment with the Company or any other member of the Group. 
 Notwithstanding anything contained herein to the contrary,

(a) Demand Registration.

delayed or continuous basis pursuant to Rule 415 pursuant to a Shelf Registration Statement (a “Demand Registration”). The Demand Notice must set forth the number of Registrable Securities that the Initiating Holder intends
to include in such Demand Registration and the intended methods of disposition thereof. Notwithstanding anything 

  
 6 

 
to the contrary herein, in no event shall the Company be required to effectuate a Demand Registration unless the Registrable Securities of the Holders to be included therein after compliance with
Section 2(a)(ii) have an aggregate value of at least $75 million based on the VWAP (the “Minimum Amount”) as of the date of the Demand Notice; provided, however, that the Minimum Amount shall not apply in the
event that, as the result of Cutback Shares being removed from such Registration Statement pursuant to this Section 2(a)(i), the Registrable Securities of the Holders to be included therein after compliance with
Section 2(a)(ii) have an aggregate value of less than $75 million. If at any time the Commission takes the position that some or all of the Registrable Securities proposed to be included in a Registration Statement filed pursuant to a
Demand Registration must be removed from such Registration Statement (such portion of the Registrable Securities, the “Cut Back Shares”) in order for all of the Registrable Securities in such Registration Statement filed
pursuant to a Demand Registration to be eligible to be made on a delayed or continuous basis under the provisions of Rule 415 or for the Initiating Holder to not be named as an “underwriter” in such Registration Statement, then if the
Initiating Holder so elects, the Company shall remove the Cutback Shares from such Registration Statement. Any Cut Back Shares so removed pursuant to this Section 2(a)(i) shall be allocated among the Holders including Registrable
Securities for resale on such Registration Statement on a pro rata basis. Further, a Demand Registration shall not constitute a Demand Registration of the Initiating Holder for purposes of Section 2(a)(iii) if, as a result of the cutback
provisions in this Section 2(a)(i) or Registrable Securities of Holders other than the Initiating Holder included in such Demand Registration pursuant to Section 2(a)(ii), there is included in the Demand Registration less
than the lesser of (x) Registrable Securities of the Initiating Holder having a VWAP measured on the effective date of the related Registration Statement of $75 million and (y) two-thirds of the number of Registrable Securities the
Initiating Holder set forth in the applicable Demand Notice. 
 (ii) Within five Business Days (or if the Registration
Statement will be a Shelf Registration Statement, within two Business Days) after the receipt of the Demand Notice, the Company shall give written notice of such Demand Notice to all Holders and, within 30 days after receipt of the Demand Notice
(except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case, within 90 days thereof), shall, subject to the limitations of this Section 2(a), file a Registration Statement in
accordance with the terms and conditions of the Demand Notice, which Registration Statement shall cover all of the Registrable Securities that the Holders shall in writing request to be included in the Demand Registration (such request to be given
to the Company within three Business Days (or if the Registration Statement will be a Shelf Registration Statement, within one Business Day) after receipt of notice of the Demand Notice given by the Company pursuant to this
Section 2(a)(ii)). The Company shall use reasonable best efforts to cause such Registration Statement to become and remain effective (including using reasonable best efforts to file a Registration Statement including Registrable
Securities included on any previous Registration Statement that ceases to be effective, which, for the avoidance of doubt shall not be considered an additional Demand Registration for any Holder pursuant to Section 2(a)(iii)) under the
Securities Act until all such securities registered for resale thereunder cease to be Registrable Securities (the “Effectiveness Period”). 

  
 7 

 (iii) Subject to the other limitations contained in this Agreement, the Company
is not obligated hereunder to effect (A) a Demand Registration within 90 days after the closing of any Underwritten Offering (or such shorter time as the Company may notify the Holders in writing) (any such time period, a “No Demand
Period”), unless any Preferred No-Blocking Period exists during such No Demand Period, in which case the Company shall nevertheless be required to effect a Demand Registration initiated by any Preferred Holder that is then otherwise
entitled to initiate a Demand Registration during such Preferred No-Blocking Period, (B) more than a total of four Demand Registrations for which WildHorse Holdings (or any transferee thereof in accordance with Section 8(e)) is the
Initiating Holder, (C) more than a total of four Demand Registrations for which Esquisto Holdings (or any transferee thereof in accordance with Section 8(e)) is the Initiating Holder, (D) more than a total of four Demand
Registrations for which Acquisition Co. Holdings (or any transferee thereof in accordance with Section 8(e)) is the Initiating Holder, (E) more than a total of six Demand Registrations for which any Preferred Holder is the
Initiating Holder; and (F) a subsequent Demand Registration pursuant to a Demand Notice if a Registration Statement covering all of the Registrable Securities held by the Initiating Holder shall have become and remains effective under the
Securities Act and is sufficient to permit offers and sales of the number and type of Registrable Securities on the terms and conditions specified in the Demand Notice in accordance with the intended timing and method or methods of distribution
thereof specified in the Demand Notice. No Demand Registration shall be deemed to have occurred for purposes of this Section 2(a)(iii) if the Registration Statement relating thereto does not become effective or is not maintained
effective for its entire Effectiveness Period, in which case the Initiating Holder shall be entitled to an additional Demand Registration in lieu thereof. 

(iv) A Holder may withdraw all or any portion of its Registrable Securities included in a Demand Registration from such Demand
Registration at any time prior to the effectiveness of the applicable Registration Statement. Upon receipt of a notice from the Initiating Holder that the Initiating Holder is withdrawing all of its Registrable Securities from the Demand
Registration or a notice from a Holder to the effect that the Holder is withdrawing an amount of its Registrable Securities such that the remaining amount of Registrable Securities to be included in the Demand Registration is below the Minimum
Amount, the Company may cease all efforts to secure effectiveness of the applicable Registration Statement, unless one or more Holders other than the withdrawing Holder(s) shall promptly request the Company in writing to include additional
Registrable Securities in the Demand Registration such that amount of Registrable Shares to be included in the Demand Registration satisfies the Minimum Amount (a “Requisite Holder Substitution”). In the absence of a
Requisite Holder Substitution, such registration nonetheless shall be deemed a Demand Registration with respect to the Initiating Holder for purposes of Section 2(a)(iii) unless (A) the Initiating Holder shall have paid or
reimbursed the Company for its pro rata share of all reasonable and documented out-of-pocket fees and expenses incurred by the Company in connection with the withdrawn registration of such Registrable Securities (based on the number of securities
the Initiating Holder sought to register, as compared to the total number of securities included in such Demand Registration) or (B) the withdrawal is made following the occurrence of a Material Adverse Change or pursuant to the Company’s
request for suspension pursuant to Section 3(o). 

  
 8 

 (v) The Company may include in any such Demand Registration other Company
Securities for sale for its own account or for the account of any other Person, subject to Section 2(c)(iii). 

(vi) Subject to the limitations contained in this Agreement, the Company shall effect any Demand Registration on such
appropriate registration form of the Commission (A) as shall be selected by the Company and (B) subject to applicable law and the requirements of the Commission, as shall permit the disposition of the Registrable Securities in accordance
with the intended method or methods of disposition specified in the Demand Notice; provided that, subject to Section 3(o), (X) if the Registration Statement is on Form S-1, the Company shall maintain the effectiveness of the
Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the Commission (provided that Form S-1 is then available for sales on a delayed or
continuous basis under the provisions of Rule 415 in respect of such Demand Registration), and (Y) if the Company becomes, and is at the time of its receipt of a Demand Notice eligible to use Form S-3, the Demand Registration for any offering
and selling of Registrable Securities shall be registered on Form S-3 (or any equivalent or successor form under the Securities Act (if available to the Company) and (Z) if at the time of its receipt of a Demand Notice, the Company is a WKSI,
the Demand Registration for any offering and selling of Registrable Securities shall be registered on an Automatic Shelf Registration Statement on Form S-3 or any equivalent or successor form under the Securities Act (if available to the Company).
If at any time a Registration Statement on Form S-3 is effective and a Holder provides written notice to the Company that it intends to effect an offering of all or part of the Registrable Securities included on such Registration Statement, the
Company will amend or supplement such Registration Statement as may be necessary in order to enable such offering to take place. 

(vii) Without limiting Section 3, in connection with any Demand Registration pursuant to and in accordance with
this Section 2(a), the Company shall (A) promptly prepare and file or cause to be prepared and filed (1) such additional forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents, as may
be necessary or advisable to register or qualify the securities subject to such Demand Registration, including under the securities laws of such jurisdictions as the Holders shall reasonably request; provided, however, that no such qualification
shall be required in any jurisdiction where, as a result thereof, the Company would become subject to general service of process or to taxation or qualification to do business in such jurisdiction solely as a result of registration and (2) such
forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents as may be necessary to apply for listing or to list the Registrable Securities subject to such Demand Registration on the Trading Market and
(B) do any and all other acts and things that may be reasonably necessary or appropriate or reasonably requested by the Holders to enable the Holders to consummate a public sale of such Registrable Securities in accordance with the intended
timing and method or methods of distribution thereof. 

  
 9 

 (viii) In the event a Holder transfers Registrable Securities included on a
Registration Statement and such Registrable Securities remain Registrable Securities following such transfer, at the request of such Holder, the Company shall amend or supplement such Registration Statement as may be necessary in order to enable
such transferee to offer and sell such Registrable Securities pursuant to such Registration Statement; provided that in no event shall the Company be required to file a post-effective amendment to the Registration Statement unless (A) such
Registration Statement includes only Registrable Securities held by the Holder, Affiliates of the Holder or transferees of the Holder or (B) the Company has received written consent therefor from a Person for whom Registrable Securities have
been registered on (but not yet sold under) such Registration Statement, other than the Holder, Affiliates of the Holder or transferees of the Holder. 

(ix) Notwithstanding the foregoing restrictions of this Section 2(a), but subject to any applicable No Demand
Periods, the Preferred Holders shall be permitted to deliver a Demand Notice for a Demand Registration during the Lock-Up Period so long as (A) the Company is then-eligible to use Form S-3 to register the resale of Registrable Securities and
(B) the Preferred Holders do not dispose of any Registrable Securities pursuant to the applicable Registration Statement for the duration of the Lock-Up Period. Further, and for the avoidance of doubt, nothing in this Agreement shall prohibit a
Preferred Holder from exercising its rights as a Holder during the Lock-Up Period, including, but not limited to, a Preferred Holder’s participation in a Demand Registration, Underwritten Offering and/or Underwritten Piggyback Offering, other
than with respect to (Y) except as provided in the immediately preceding sentence, delivering a Demand Notice as an Initiating Holder during its Lock-Up Period pursuant to Section 2(a)(i) and (Z) exercising its right to receive
a Piggyback Notice or to participate in any Piggyback Registration during its Lock-Up Period with respect to the filing of a registration statement for the sale of securities solely for the account of the Company, which registration statement, for
the avoidance of doubt, does not include Registrable Securities of any Holder. 
 (b) Requested Underwritten Offering. Any Holder then
able to effectuate a Demand Registration pursuant to the terms of Section 2(a) (or who has previously effectuated a Demand Registration pursuant to Section 2(a) but has not engaged in an Underwritten Offering in respect of
such Demand Registration) shall have the option and right, exercisable by delivering written notice to the Company of its intention to distribute Registrable Securities by means of an Underwritten Offering (an “Underwritten Offering
Notice”), to require the Company, pursuant to the terms of and subject to the limitations of this Agreement, to effectuate a distribution of any or all of its Registrable Securities by means of an Underwritten Offering pursuant to a new
Demand Registration or pursuant to an effective Registration Statement covering such Registrable Securities (a “Requested Underwritten Offering”); provided, that the Registrable Securities of such Initiating Holder requested
to be included in such Requested Underwritten Offering have an aggregate value of at least equal to the Minimum Amount as of the date of such Underwritten Offering Notice. The Underwritten Offering Notice must set forth the number of Registrable
Securities that the Initiating Holder intends to include in such Requested Underwritten Offering. The managing underwriter or managing underwriters of a Requested Underwritten Offering shall be designated by the Company; provided, however, that

  
 10 

 
such designated managing underwriter or managing underwriters shall be reasonably acceptable to the Initiating Holder; provided, further, however that no later than 9:00 A.M., New York Time, on
the day of a proposed block trade or bought deal pursuant to an Initiating Holder’s Requested Underwritten Offering (an “Initiating Holder Block”), the Initiating Holder thereof may deliver to the Company in writing a
list of one or more proposed managing underwriters of the Initiating Holder Block (each a “Bidding Bank” and collectively, the “Bidding Banks”) and, unless the Company reasonably objects to any Bidding
Bank in writing to the Initiating Holder by Noon, New York Time on the same day, any one or more of such Bidding Banks to which the Company does not so timely reasonably object (the “Approved Bidding Banks”), shall be deemed
to be designated by the Company as a managing underwriter for the purposes of this Section 2(b), and the Initiating Holder of the Initiating Holder Block may select, without any additional prior consent by or approval from the Company,
one or more Approved Bidding Bank as a managing underwriter or the managing underwriters for such Initiating Holder Block as if it as if it had assumed the Company’s the right of designation pursuant to this Section 2(b). In
connection with any Initiating Holder Block, the Initiating Holder thereof shall take commercially reasonable efforts to advise the Company with respect to its obligations thereunder and related schedule thereto. Notwithstanding the foregoing, the
Company is not obligated to effect a Requested Underwritten Offering within 90 days after the closing of an Underwritten Offering (or such shorter time as the Company may notify the Holders in writing) (any such time period, a “No
Requested Underwritten Offering Period”), unless any Preferred No-Blocking Period exists during such No Requested Underwritten Offering Period, in which case the Company shall nevertheless be required to effect a Requested Underwritten
Offering initiated by any Preferred Holder that is then otherwise entitled to initiate a Requested Underwritten Offering during such Preferred No-Blocking Period. Any Requested Underwritten Offering (other than the first Requested Underwritten
Offering made in respect of a prior Demand Registration) shall constitute a Demand Registration of the Initiating Holder for purposes of Section 2(a)(iii) (it being understood that if requested concurrently with a Demand Registration
then, together, such Demand Registration and Requested Underwritten Offering shall count as one Demand Registration); provided, however, that a Requested Underwritten Offering shall not constitute a Demand Registration of the Initiating Holder for
purposes of Section 2(a)(iii) if, as a result of Section 2(c)(iii)(A), the Requested Underwritten Offering includes less than the lesser of (i) Registrable Securities of the Initiating Holder having a VWAP measured on
date of the applicable Underwritten Offering Notice of $75 million and (ii) two-thirds of the number of Registrable Securities the Initiating Holder set forth in the applicable Underwritten Offering Notice. 

(c) Piggyback Registration and Piggyback Underwritten Offering. 

(i) If the Company shall at any time propose to file a registration statement under the Securities Act with
respect to an offering of Common Stock (other than a registration statement on Form S-4, Form S-8 or any successor forms thereto or filed solely in connection with an exchange offer or any employee benefit or dividend reinvestment plan and other
than a Demand Registration), whether or not for its own account, then the Company shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least five Business Days, except if the registration statement will be
a Shelf Registration Statement, at least two Business Days, before) the anticipated filing date (the “Piggyback Registration Notice”). The Piggyback  

  
 11 

 
Registration Notice shall offer Holders the opportunity to include for registration in such registration statement the number of Registrable Securities as they may request in writing (a
“Piggyback Registration”). The Company shall use commercially reasonable efforts to include in each such Piggyback Registration such Registrable Securities for which the Company has received written requests for inclusion
therein (“Piggyback Registration Request”) within three Business Days or, if the Piggyback Registration will be on a Shelf Registration Statement, within one Business Day, after sending the Piggyback Registration Notice. Each
Holder shall be permitted to withdraw all or part of such Holder’s Registrable Securities from a Piggyback Registration by giving written notice to the Company of its request to withdraw; provided that (A) such request must be made in
writing prior to the effectiveness of such registration statement and (B) such withdrawal shall be irrevocable and, after making such withdrawal, a Holder shall no longer have any right to include Registrable Securities in the Piggyback
Registration as to which such withdrawal was made. Any withdrawing Holder shall continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with
respect to offerings of Common Stock, all upon the terms and conditions set forth herein. Notwithstanding anything to the contrary in this Section 2(c)(i), the Preferred Holders shall not have the right to receive any Piggyback Notice or
to participate in any Piggyback Registration, in each case with respect to the filing of a registration statement for the sale of securities solely for the account of the Company, which registration statement, for the avoidance of doubt, does not
include Registrable Securities of any Holder, until the expiration of the Lock-Up Period applicable to the Preferred Holders. 

(ii) If the Company shall at any time propose to conduct an Underwritten Offering (including a Requested
Underwritten Offering), whether or not for its own account, then the Company shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least five Business Days, except if the Underwritten Offering will be made
pursuant to a Shelf Registration Statement, at least two Business Days, before) the commencement of the offering, which notice shall set forth the principal terms and conditions of the issuance, including the proposed offering price or range of
offering prices (if known), the anticipated filing date of the related registration statement (if applicable) and the number of shares of Common Stock that are proposed to be registered (the “Underwritten Offering Piggyback
Notice”). The Underwritten Offering Piggyback Notice shall offer Holders the opportunity to include in such Underwritten Offering (and any related registration, if applicable) the number of Registrable Securities as they may request in
writing (an “Underwritten Piggyback Offering”); provided, however, that in the event that the Company proposes to effectuate the subject Underwritten Offering pursuant to an effective Shelf Registration Statement other than
an Automatic Shelf Registration Statement, only Registrable Securities of Holders which are subject to an effective Shelf Registration Statement may be included in such Underwritten Piggyback Offering. The Company shall use commercially reasonable
efforts to include in each such Underwritten Piggyback Offering such Registrable Securities for which the Company has received written requests for inclusion therein (“Underwritten Offering Piggyback Request”) within three
Business Days or, if such Underwritten Piggyback Offering will be made pursuant to a Shelf Registration Statement, within one Business Day after sending the Underwritten Offering Piggyback 

  
 12 

 
Notice. Each Holder shall be permitted to withdraw all or part of such Holder’s Registrable Securities from an Underwritten Piggyback Offering at any time prior to the effectiveness of the
applicable registration statement, and such Holder shall continue to have the right to include any Registrable Securities in any subsequent Underwritten Offerings, all upon the terms and conditions set forth herein. Notwithstanding anything to the
contrary in this Section 2(c)(ii), the Preferred Holders shall not have the right to receive any Underwritten Offering Piggyback Notice or to participate in any Underwritten Piggyback Offering, in each case with respect to an
Underwritten Offering of securities solely for account of the Company (and not including Registrable Securities of any other Holder), until the expiration of the Lock-Up Period applicable to the Preferred Holders. 

(iii) If the managing underwriter or managing underwriters of an Underwritten Offering advise the Company and the Holders that
in their reasonable opinion that the inclusion of all of the Holders’ Registrable Securities requested for inclusion in the subject Underwritten Offering (and any related registration, if applicable) (and any other Common Stock proposed to be
included in such offering) exceeds the number that can be included without being likely to have a significant adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, the Company shall
include in such Underwritten Offering (and any related registration, if applicable) only that number of shares of Common Stock proposed to be included in such Underwritten Offering (and any related registration, if applicable) that, in the
reasonable opinion of the managing underwriter or managing underwriters, will not have such adverse effect, with such number to be allocated as follows: (A) in the case of a Requested Underwritten Offering, (1) first, pro-rata among all
Holders (including the Initiating Holder) that have requested to include Registrable Securities in such Underwritten Offering based on the relative number of Registrable Securities then held by each such Holder, (2) second, if there remains
availability for additional shares of Common Stock to be included in such Underwritten Offering, the Company, and (3) third, if there remains availability for additional shares of Common Stock to be included in such Underwritten Offering, any
other holders entitled to participate in such Underwritten Offering, if applicable, based on the relative number of shares of Common Stock then held by each such holder; and (B) in the case of any other Underwritten Offerings, (x) first,
to the Company, (y) second, if there remains availability for additional shares of Common Stock to be included in such Underwritten Offering, pro-rata among all Holders desiring to include Registrable Securities in such Underwritten Offering
based on the relative number of Registrable Securities then held by each such Holder, and (z) third, if there remains availability for additional shares of Common Stock to be included in such registration, pro-rata among any other holders
entitled to participate in such Underwritten Offering, if applicable, based on the relative number of Common Stock then held by each such holder. If any Holder disapproves of the terms of any such Underwritten Offering, such Holder may elect to
withdraw therefrom by written notice to the Company and the managing underwriter(s) delivered on or prior to the time of the commencement of such offering. Any Registrable Securities withdrawn from such underwriting shall be excluded and withdrawn
from the registration. In making any determination of the relative number of Registrable Securities then held by each Holder for purposes of Section 2(a)(iv) and this Section 2(c)(iii), each Holder of Convertible

  
 13 

 
Preferred Stock shall be deemed for purposes of such determination to hold a number of shares of Common Stock equal to the number of shares of Common Stock issuable in respect of such
Holder’s Convertible Preferred Stock in the event such Holder converted all of its shares of Convertible Preferred Stock into shares of Common Stock as of such time of determination. 

(iv) The Company shall have the right to terminate or withdraw any registration initiated by it under this
Section 2(c) at any time in its sole discretion whether or not any Holder has elected to include Registrable Securities in such Registration Statement. The registration expenses of such withdrawn registration shall be borne by the
Company in accordance with Section 4 hereof. 
 (v) Each Holder agrees that, following receipt of any Piggyback
Registration Notice, Underwritten Offering Piggyback Notice or any notice pursuant to Section 2(a)(ii), such Holder will keep confidential and will not disclose, divulge, or use for any purpose (other than as necessary to exercise its
rights pursuant to this Agreement, including, but not limited to, disclosure to its advisors and Affiliates) the fact that such Piggyback Registration Notice, Underwritten Offering Piggyback Notice or any notice pursuant to
Section 2(a)(ii) exists or was received by such Holder or the contents of any such Piggyback Registration Notice, Underwritten Offering Piggyback Notice or any notice pursuant to Section 2(a)(ii), until the earlier of
(a) the date that is 30 days following receipt of such notice, (b) such time as the registration or Underwritten Offering that is the subject of such notice is known or becomes known to the public in general (other than as a result of a
breach of this Section 2(c)(v)) and (c) the date the Company notifies the Holder that the proposed Underwritten Piggyback offering has been abandoned. 

3. Registration and Underwritten Offering Procedures. The procedures to be followed by the Company and each Holder electing to
sell Registrable Securities in a Registration Statement pursuant to this Agreement, and the respective rights and obligations of the Company and such Holders, with respect to the preparation, filing and effectiveness of such Registration Statement
and the effectuation of any Underwritten Offering, are as follows: 
 (a) In connection with a Demand Registration, the Company will, at
least three Business Days prior to the anticipated filing of the Registration Statement and any related Prospectus or any amendment or supplement thereto (other than, after effectiveness of the Registration Statement, any filing made under the
Exchange Act that is incorporated by reference into the Registration Statement), (i) furnish to such Holders copies of all such documents prior to filing and (ii) use commercially reasonable efforts to address in each such document when so
filed with the Commission such comments as such Holders reasonably shall propose prior to the filing thereof. 
 (b) In connection with a
Piggyback Registration, Underwritten Piggyback Offering or a Requested Underwritten Offering, the Company will, at least three Business Days (or in the case of a Shelf Registration Statement or an offering that will be made pursuant to a Shelf
Registration Statement, at least one Business Day) prior to the anticipated filing of any initial Registration Statement that identifies the Holders and any related Prospectus or any 

  
 14 

 
amendment or supplement thereto (other than amendments and supplements that do not materially alter the previous disclosure or do nothing more than name Holders and provide information with
respect thereto), as applicable, furnish to such Holders copies of any such Registration Statement or related Prospectus or amendment or supplement thereto that identify the Holders and any related Prospectus or any amendment or supplement
thereto (other than amendments and supplements that do not materially alter the previous disclosure or do nothing more than name Holders and provide information with respect thereto). The Company will also use commercially reasonable efforts to
address in each such document when so filed with the Commission such comments as such Holders reasonably shall propose prior to the filing thereof. 

(c) The Company will use commercially reasonable efforts to as promptly as reasonably practicable (i) prepare and file with the Commission
such amendments, including post-effective amendments, and supplements to each Registration Statement and the Prospectus used in connection therewith as may be necessary under applicable law to keep such Registration Statement continuously effective
with respect to the disposition of all Registrable Securities covered thereby for its Effectiveness Period and, subject to the limitations contained in this Agreement, applicable law and the requirements of the Commission, prepare and file with the
Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities held by the Holders; (ii) cause the related Prospectus to be amended or supplemented by any required
prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; and (iii) respond to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and, as promptly as
reasonably practicable provide such Holders true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that pertains to such Holders as selling stockholders but not any comments that would
result in the disclosure to such Holders of material and non-public information concerning the Company. 
 (d) The Company will comply in all
material respects with the provisions of the Securities Act and the Exchange Act with respect to the Registration Statements and the disposition of all Registrable Securities covered by each Registration Statement. 

(e) The Company will notify such Holders who are included in a Registration Statement as promptly as reasonably practicable: (i)(A) when a
Prospectus or any prospectus supplement or post-effective amendment to a Registration Statement in which such Holder is included has been filed; (B) when the Commission notifies the Company whether there will be a “review” of the
applicable Registration Statement and whenever the Commission comments in writing on such Registration Statement (in which case the Company shall provide true and complete copies thereof and all written responses thereto to each of such Holders that
pertain to such Holders as selling stockholders); and (C) with respect to each applicable Registration Statement or any post-effective amendment thereto, when the same has been declared effective; (ii) of any request by the Commission or
any other federal or state governmental authority for amendments or supplements to such Registration Statement or Prospectus or for additional information that pertains to such Holders as sellers of Registrable Securities; (iii) of the issuance
by the Commission of any stop order suspending the effectiveness of such Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable 

  
 15 

 
Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (v) of the occurrence of any event or passage of time that makes any
statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or
other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they were made, not misleading (provided, however, that no notice by the Company shall be required pursuant to this clause (v) in the event that the Company either
promptly files a prospectus supplement to update the Prospectus or a Form 8-K or other appropriate Exchange Act report that is incorporated by reference into the Registration Statement, which in either case, contains the requisite information that
results in such Registration Statement no longer containing any untrue statement of material fact or omitting to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not
misleading). 
 (f) The Company will use commercially reasonable efforts to avoid the issuance of or, if issued, obtain the withdrawal of
(i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as promptly as
reasonably practicable, or if any such order or suspension is made effective during any Blackout Period or Suspension Period, as promptly as reasonably practicable after such Blackout Period or Suspension Period is over. 

(g) During the Effectiveness Period, the Company will furnish to each such Holder, without charge, at least one conformed copy of each
Registration Statement and each amendment thereto and all exhibits to the extent requested by such Holder (including those incorporated by reference) promptly after the filing of such documents with the Commission; provided, that the Company will
not have any obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system. 
 (h) The
Company will promptly deliver to each Holder, without charge, as many copies of each Prospectus or Prospectuses (including each form of prospectus) authorized by the Company for use and each amendment or supplement thereto as such Holder may
reasonably request during the Effectiveness Period. Subject to the terms of this Agreement, including Section 8(b), the Company consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto. 

(i) The Company will cooperate with such Holders to facilitate the timely preparation and delivery of certificates representing Registrable
Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free of all restrictive legends indicating that the Registrable Securities are unregistered or unqualified for resale under the Securities
Act, Exchange Act or other applicable securities laws, and to enable such Registrable Securities to be in such denominations and registered in such names as any such 

  
 16 

 
Holder may request in writing. In connection therewith, if required by the Company’s transfer agent, the Company will promptly, after the Effective Date of the Registration Statement, cause
an opinion of counsel as to the effectiveness of the Registration Statement to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent which authorize
and direct the transfer agent to issue such Registrable Securities without any such legend upon sale by the Holder of such Registrable Securities under the Registration Statement. 

(j) Upon the occurrence of any event contemplated by Section 3(e)(v), as promptly as reasonably practicable, the Company will
prepare a supplement or amendment, including a post-effective amendment, if required by applicable law, to the affected Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
 (k)
With respect to Underwritten Offerings, (i) the right of any Holder to include such Holder’s Registrable Securities in an Underwritten Offering shall be conditioned upon such Holder’s participation in such underwriting and the
inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein, (ii) each Holder participating in such Underwritten Offering agrees to enter into an underwriting agreement in customary form and sell
such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled to select the managing underwriter or managing underwriters hereunder and (iii) each Holder participating in such
Underwritten Offering agrees to complete and execute all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents customarily and reasonably required under the terms of such underwriting arrangements. The Company
hereby agrees with each Holder that, in connection with any Underwritten Offering in accordance with the terms hereof, it will negotiate in good faith and execute all indemnities, underwriting agreements and other documents reasonably required under
the terms of such underwriting arrangements, including using all commercially reasonable efforts to procure customary legal opinions, auditor “comfort” letters and reports of the independent petroleum engineers of the Company relating to
the oil and gas reserves of the Company included in the Registration Statement if the Company has had its reserves prepared, audited or reviewed by an independent petroleum engineer. 

(l) For a reasonable period prior to the filing of any Registration Statement and throughout the Effectiveness Period, the Company will make
available, upon reasonable notice at the Company’s principal place of business or such other reasonable place, for inspection during normal business hours by a representative or representatives of the selling Holders, the managing underwriter
or managing underwriters and any attorneys or accountants retained by such selling Holders or underwriters, all such financial and other information and books and records of the Company, and cause the officers, employees, counsel and independent
certified public accountants of the Company to respond to such inquiries, as shall be reasonably necessary (and in the case of counsel, not violate an attorney-client privilege in such counsel’s reasonable belief) to conduct a reasonable
investigation within the meaning of Section 11 of the 

  
 17 

 
Securities Act; provided, however, that any information that is not generally publicly available at the time of delivery of such information shall be kept confidential by such Persons unless
disclosure of such information is required by court or administrative order or, in the opinion of counsel to such Person, law, in which case, such Person shall be required to give the Company written notice of the proposed disclosure prior to such
disclosure and, if requested by the Company, assist the Company in seeking to prevent or limit the proposed disclosure. 
 (m) In connection
with any Requested Underwritten Offering, the Company will use commercially reasonable efforts to cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors in
presentations, meetings and road shows. 
 (n) Each Holder agrees to furnish to the Company any other information regarding the Holder and
the distribution of such securities as the Company reasonably determines is required to be included in any Registration Statement or any Prospectus or prospectus supplement relating to an Underwritten Offering. 

(o) Notwithstanding any other provision of this Agreement, the Company shall not be required to file a Registration Statement (or any amendment
thereto) or effect a Requested Underwritten Offering (or, if the Company has filed a Shelf Registration Statement and has included Registrable Securities therein, the Company shall be entitled to suspend the offer and sale of Registrable Securities
pursuant to such Registration Statement) for a period of up to 60 days if (i) the Board determines that a postponement is in the best interest of the Company and its stockholders generally due to a pending transaction involving the Company
(including a pending securities offering by the Company), (ii) the Board determines such registration would render the Company unable to comply with applicable securities laws or (iii) the Board determines such registration would require
disclosure of material information that the Company has a bona fide business purpose for preserving as confidential (any such period, a “Blackout Period”); provided, however, that in no event shall any Blackout Period
together with any Suspension Period, any No Demand Period (but only if such No Demand Period relates to a an Underwritten Offering other than a Requested Underwritten Offering in which the Preferred Holders participated) and any No Requested
Underwritten Offering Period (but only if such No Demand Period relates to a an Underwritten Offering other than a Requested Underwritten Offering in which the Preferred Holders participated) collectively exceed an aggregate of 120 days in any
12-month period; provided, further, that nothing in this Section 3(o) shall (i) relieve the Company of any obligation it may otherwise have pursuant to this Agreement to file a Registration Statement (or any amendment thereto) or
effect a Requested Underwritten Offering or (ii) permit the Company to suspend the offer and sale of Registrable Securities pursuant to a Shelf Registration Statement that has been previously filed pursuant to this Agreement, in each case at
the request of or with respect to a Preferred Holder or with respect to Registrable Securities of any such Preferred Holder, within any 45-day period following the date upon which any Convertible Preferred Stock of such Preferred Holder is converted
into shares of Common Stock pursuant to Section 7(b) of the Certificate (any such 45-day period, a “Preferred No-Blocking Period”). 

  
 18 

 (p) In connection with an Underwritten Offering, the Company shall use all commercially
reasonable efforts to provide to each Holder named as a selling securityholder in any Registration Statement a copy of any auditor “comfort” letters, customary legal opinions or reports of the independent petroleum engineers of the Company
relating to the oil and gas reserves of the Company, in each case that have been provided to the managing underwriter or managing underwriters in connection with the Underwritten Offering, not later than the Business Day prior to the effective date
of such Registration Statement. 
 (q) In connection with any Underwritten Offering (including any Requested Underwritten Offering), any
Holder that (i) together with its Affiliates owns five percent (5%) or more of the outstanding Common Stock (assuming all Convertible Preferred Stock held by any Holder has been converted to Common Stock) or (ii) is entitled (or any
of its Affiliates is entitled) to designate a director to the Company’s board of directors pursuant to the Stockholders Agreement or to elect a director to the Company’s board of directors pursuant to the Certificate, shall execute a
customary “lock-up” agreement with the underwriters of such Underwritten Offering containing a lock-up period equal to the shorter of (A) the shortest number of days that a director of the Company, “executive officer” (as
defined under Section 16 of the Exchange Act) of the Company or any stockholder of the Company (other than a Holder or director or employee of, or consultant to, the Company) who owns five percent (5%) or more of the outstanding Common
Stock contractually agrees to with the underwriters of such Underwritten Offering not to sell any securities of the Company following such Underwritten Offering and (B) 45 days from the date of the execution of the underwriting agreement with
respect to such Underwritten Offering. 
 (r) In connection with any Requested Underwritten Offering, the Company will, and will use its
commercially reasonable efforts to cause the members of the Board of Directors of the Company and the officers of the Company that are “executive officers” as defined under Section 16 of the Exchange Act to, execute a customary
“lock-up” agreement with the underwriters of such Requested Underwritten Offering containing a lock-up period equal to the shorter of (A) the number of days that the Initiating Holder in such Requested Underwritten Offering
contractually agrees with the underwriters of such Requested Underwritten Offering not to sell securities of the Company following such Requested Underwritten Offering and (B) 45 days from the date of the execution of the underwriting agreement
with respect to such Requested Underwritten Offering. 
 4. No Inconsistent Agreements; Additional Rights. The Company shall
not hereafter enter into, and is not currently a party to, any agreement with respect to its securities that is inconsistent in any material respect with the rights granted to the Holders by this Agreement. 

5. Registration Expenses. All Registration Expenses incident to the Parties’ performance of or compliance with their
respective obligations under this Agreement or otherwise in connection with any Demand Registration, Requested Underwritten Offering, Piggyback Registration or Underwritten Piggyback Offering (in each case, excluding any Selling Expenses) shall be
borne by the Company, whether or not any Registrable Securities are sold pursuant to a Registration Statement. “Registration Expenses” shall include, without limitation, (i) all registration and filing fees (including
fees and expenses (A) with respect to filings required to be made with the Trading Market, (B) in compliance with applicable state securities or “Blue Sky” laws and (C) FINRA fees and expenses associated with any
Registration Statement and the 

  
 19 

 
FINRA filing obligations of any underwriter related thereto), (ii) printing expenses (including expenses of printing certificates for Company Securities and of printing Prospectuses if the
printing of Prospectuses is reasonably requested by a Holder of Registrable Securities included in the Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel, auditors, accountants
and independent petroleum engineers for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, (vi) fees and expenses of all other Persons retained by the Company in connection with the consummation
of the transactions contemplated by this Agreement, and (vii) all expenses relating to marketing the sale of the Registrable Securities, including expenses related to conducting a “road show.” In addition, the Company shall be
responsible for all of its expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including expenses payable to third parties and including all salaries and expenses of their officers and employees
performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on the Trading Market. 

6. Indemnification. 

(a) The Company shall indemnify and hold harmless each Holder, its Affiliates and each of their respective officers and directors
and any agent thereof (collectively, “Holder Indemnified Persons”), to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, joint or several, costs (including
reasonable costs of preparation and reasonable attorneys’ fees) and expenses, judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal,
administrative or investigative, in which any Holder Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), as incurred,
arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which any Registrable Securities were registered, in any preliminary prospectus (if the Company authorized the use
of such preliminary prospectus prior to the Effective Date), or in any summary or final prospectus or free writing prospectus (if such free writing prospectus was authorized for use by the Company) or in any amendment or supplement thereto (if used
during the period the Company is required to keep the Registration Statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to
make the statements made therein, in the light of the circumstances in which they were made, not misleading; provided, however, that the Company shall not be liable to any Holder Indemnified Person to the extent
that any such claim arises out of, is based upon or results from an untrue or alleged untrue statement or omission or alleged omission made in such Registration Statement, such preliminary, summary or final prospectus or free writing prospectus or
such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder Indemnified Person or any underwriter specifically for use therein, it being understood and agreed that
the only such information so furnished by any Holder to the Company consists of (A) the legal name and address of the Holder set forth in its footnote that appears under the caption “Principal and Selling Stockholders” of any such
Registration Statement, such preliminary, summary or final prospectus and (B) the number of shares of Common Stock or Convertible Preferred Stock, as applicable, owned by the Holder 

  
 20 

 
before and after the offering (excluding percentages) that appears in the table (and corresponding footnotes) under the caption “Principal and Selling Stockholders” of any such
Registration Statement, such preliminary, summary or final prospectus (the “Selling Stockholder Information”). The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which
the Company is aware in connection with the transactions contemplated by this Agreement. This indemnity shall be in addition to any liability the Company may otherwise have and shall remain in full force and effect regardless of any investigation
made by or on behalf of such Holder Indemnified Person or any indemnified party and shall survive the transfer of such securities by such Holder. Notwithstanding anything to the contrary herein, this Section 6 shall survive any
termination or expiration of this Agreement indefinitely. 
 (b) In connection with any Registration Statement in which a Holder
participates, such Holder shall, severally and not jointly, indemnify and hold harmless the Company, its Affiliates and each of their respective officers, directors and any agent thereof, to the fullest extent permitted by applicable law, from and
against any and all Losses as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any such Registration Statement, in any preliminary prospectus (if used prior to the Effective Date of such
Registration Statement), or in any summary or final prospectus or free writing prospectus or in any amendment or supplement thereto (if used during the period the Company is required to keep the Registration Statement current), or arising out of,
based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances in which they were made, not misleading,
but only to the extent that any such claim arises out of, is based upon or results from an untrue or alleged untrue statement or omission or alleged omission made in such Registration Statement, such preliminary, summary or final prospectus or free
writing prospectus or such amendment or supplement, in reliance upon and in conformity with such Holder’s Selling Stockholder Information. This indemnity shall be in addition to any liability such Holder may otherwise have and shall remain in
full force and effect regardless of any investigation made by or on behalf of the Company or any indemnified party. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the proceeds received
by such Holder from the sale of the Registrable Securities giving rise to such indemnification obligation. 
 (c) Any Person entitled to
indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of
interest between such indemnified and indemnifying parties may exist with respect to such claim or there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying
party, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of
more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may

  
 21 

 
be one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another indemnified party with respect to such
claim. Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder. 
 (d) If the
indemnification provided for in this Section 6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any Losses referred to herein, the indemnifying party, in lieu of indemnifying such
indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the
indemnifying party, on the one hand, and of the indemnified party, on the other, in connection with the untrue or alleged untrue statement of a material fact or the omission to state a material fact that resulted in such Losses, as well as any other
relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such
statement or omission; provided, that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder. 

7. Facilitation of Sales Pursuant to Rule 144. To the extent it shall be required to do so under the Exchange Act, the
Company shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), and shall take such
further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by
Rule 144. Upon the request of any Holder in connection with that Holder’s sale pursuant to Rule 144, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. 

8. Miscellaneous. 

(a) Remedies. In the event of actual or potential breach by the Company of any of its obligations under this Agreement, each Holder, in
addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company agrees that monetary damages would not
provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate. 
 (b) Discontinued Disposition. Each Holder agrees that, upon receipt of a notice
from the Company of the occurrence of any event of the kind described in clauses (ii) through (v) of Section 3(e), such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration
Statement until such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement as contemplated by Section  

  
 22 

 
3(j) or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental
filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement (a “Suspension Period”). The Company may provide appropriate stop orders to enforce the provisions of
this Section 8(b). 
 (c) Amendments and Waivers. No provision of this Agreement may be waived or amended except in a written
instrument signed by the Company and Holders that hold a majority of the Registrable Securities (counting Convertible Preferred Stock held by any Preferred Holder as Registrable Securities on an as-converted basis to Common Stock as provided in the
Certificate) as of the date of such waiver or amendment; provided, that any waiver or amendment that would have a disproportionate adverse effect on a Holder relative to the other Holders shall require the consent of such Holder. The Company shall
provide prior notice to all Holders of any proposed waiver or amendment. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any
subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any Party to exercise any right hereunder in any manner impair the exercise of any such right. 

(d) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in
writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Section 8(d) prior to 5:00 p.m. in
the time zone of the receiving party on a Business Day, (ii) the Business Day after the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Agreement later than 5:00 p.m. in
the time zone of the receiving party on any date, (iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service or (iv) upon actual receipt by the Party to whom such notice is required to
be given. The address for such notices and communications shall be as follows:

 (e) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit
of the Parties hereto and their respective heirs, executors, administrators, successors, legal representatives and permitted assigns. Except as provided in this Section 8(e), this Agreement, and any rights or obligations hereunder, may
not be assigned or directly or indirectly transferred without the prior written consent of the Company and the Holders. Notwithstanding anything in the foregoing to the contrary, the rights of a Holder pursuant to this Agreement with respect to all
or any portion of its Registrable Securities may be assigned or transferred without such consent (but only with all related obligations) with respect to such Registrable Securities (and any Registrable Securities issued as a dividend or other
distribution with respect to, in exchange for or in replacement of such Registrable Securities) by such Holder in connection with an assignment or transfer of (i) Registrable Securities to an Affiliate of such Holder, (ii) Registrable
Securities with an aggregate VWAP (assuming any Convertible Preferred Stock that is the subject of such transfer has been converted to Common Stock pursuant to the Certificate and the Registrable Securities being transferred consist of such Common
Stock) of at least $75 million, or (iii) in the case of the KKR Holders, in connection with the transfer of all of the Registrable Securities held by the KKR Holders and all other Holders that are Affiliates of the KKR Holders, provided such
transfer consists of at least two-thirds of the Registrable Securities held by the KKR Holders as of the date of this Agreement, in each case provided that (A) the Company is, within a reasonable time after such transfer, furnished with written
notice of the name and address of such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned and (B) such transferee or assignee agrees in writing to be bound by and subject to
the terms set forth in this Agreement. The Company may not assign its rights or obligations hereunder without the prior written consent of the Holders. 

(f) No Third Party Beneficiaries. Nothing in this Agreement, whether express or implied, shall be construed to give any Person, other
than the parties hereto or their respective successors and permitted assigns, any legal or equitable right, remedy, claim or benefit under or in respect of this Agreement. 

(g) Execution and Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed shall be
deemed to be an original and all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile or electronic mail transmission, such signature shall create a valid binding obligation
of the Party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such signature delivered by facsimile or electronic mail transmission were the original thereof. 

(h) Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with,
the internal laws of the State of New York. Each of the Parties irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in in the Borough of Manhattan in the City of New York and the United States District
Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the 

  
 24 

 
transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each Party anywhere in the world by the same methods as are
specified for the giving of notices under this Agreement. Each of the Parties irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit,
action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN
CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
 (i) Cumulative Remedies. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law. 
 (j) Severability. If any term, provision, covenant or restriction of this Agreement is
held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected,
impaired or invalidated, and the Parties shall use their reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It
is hereby stipulated and declared to be the intention of the Parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or
unenforceable. 
 (k) Entire Agreement. This Agreement constitutes the entire agreement among the Parties with respect to the subject
matter hereof and supersedes all prior contracts or agreements with respect to the subject matter hereof and the matters addressed or governed hereby, whether oral or written. 

(l) Transfers of Common Stock by Sponsoring Holders and NGP. From the date hereof until the date that both (i) the Schedule 14C
Waiting Period (as defined in the Preferred Purchase Agreement) has expired and (ii) the earlier of (A) 60 days following the date of this Agreement and (B) the date on which all approvals and authorizations of, filings and
registrations with, and notifications to, or expiration or termination of any applicable waiting period, under the HSR Act (as defined in the Preferred Purchase Agreement) required with respect to the Preferred Voting and Conversion Features (as
defined in the Preferred Purchase Agreement) of the Convertible Preferred Stock held by Carlyle have been obtained, made, expired or terminated, as applicable, the Sponsoring Holders and NGP shall not, without the prior written consent of Carlyle,
(A) sell, transfer, assign, or otherwise dispose of, directly or indirectly (collectively, a “Transfer”), any shares of the Company’s capital stock held or beneficially owned by such Sponsoring Holder or NGP, as
applicable, except that any Sponsoring Holder or NGP may Transfer any shares of Common Stock held by it to an Affiliate, provided such Affiliate agrees in writing to be bound by and subject to the terms set forth in this Agreement or (B) make
any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a short sale of or the purpose of which is to offset the loss which results from a decline in the market price
of, any shares of the Company’s capital stock, or otherwise establish or increase, directly or indirectly, a put equivalent position, as defined in Rule 16a-1(h) under the Exchange Act, with respect to any of the Company’s capital stock.

  
 25 

 (m) Termination. Except for Section 6 and Section 8(m), this
Agreement shall terminate as to any Holder, when all Registrable Securities held by such Holder no longer constitute Registrable Securities.
