 Portions of this exhibit marked [*] are requested to be treated confidentially. 
 EMPLOYMENT AGREEMENT 
 THIS EMPLOYMENT AGREEMENT (the
“Agreement”), is made and entered into on this 15th
 day of January, 2010, to be effective on the 15th day of January, 2010 (the “Effective Date”), by and between PPD Therapeutics, Inc., a Delaware corporation (the
“Company”), with its principal place of business in North Carolina and currently with a mailing address for notice purposes of 929 North Front Street, Wilmington, North Carolina 28401, Attention: President, and Paul S. Covington, MD
(“Employee”), an individual whose mailing address for notice purposes is 3116 Braemar Lane, Wilmington, North Carolina 28409. 
 RECITALS 
 A. Before Employee and the Company entered into this Agreement,
Pharmaceutical Product Development, Inc. (“PPDI”) announced its plan to spin off its compound partnering business into a separate, publicly-traded entity (the “Spin-Off”). 
 B. The Company is a wholly-owned subsidiary of PPDI and was formed for the purpose of owning and operating PPDI’s compound partnering
business prior to and after the Spin-Off. 
 C. PPDI and the Company currently anticipate that the Spin-Off will be accomplished
through a pro rata dividend of all of the common stock of the Company to the shareholders of PPDI and will be completed by mid-2010. 
 D. The Company desires to employ Employee and Employee desires to be employed by the Company, all upon the terms and conditions set forth herein. 
 NOW, THEREFORE, in consideration of the foregoing recitals, the mutual covenants of the parties hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereby agree as follows: 
 ARTICLE 1 
 EMPLOYMENT AND DUTIES 
 1.1 Employment of Employee. On the Effective Date, the Company agrees to employ Employee and Employee accepts such employment pursuant and subject to the terms and conditions of this Agreement.

 1.2. Duties and Powers. During the Employment Period (as defined herein), Employee shall serve as Senior Vice
President, Clinical Operations of the Company and will have such responsibilities, duties and authority, and will render such services for and in connection with the Company and its affiliates as are customary in such position and as the President
of the Company shall from time to time reasonably direct. Employee shall

 
devote Employee’s full business time and attention exclusively to the business of the Company and shall use best efforts to faithfully carry out Employee’s duties and responsibilities
hereunder. Employee shall comply with all personnel policies and procedures of the Company as the same now exist or may be hereafter implemented by the Company from time to time, including those policies contained in the Company’s employee
manual or handbook which sets forth policies and procedures generally for employees of the Company and its current or future subsidiaries (the “Handbook”) to the extent not inconsistent with this Agreement. 
 ARTICLE 2 
 TERM
OF EMPLOYMENT 
 Unless sooner terminated as provided elsewhere in this Agreement, Employee’s employment under this
Agreement shall begin the Effective Date and end on the first anniversary thereof (“Initial Employment Period”). After the Initial Employment Period, this Agreement shall automatically renew for successive one-year periods, unless either
the Company or Employee provides written notice to the other at least ninety (90) days prior to the termination of the Initial Employment Period or any renewal period stating said party’s desire to terminate this Agreement. The Initial
Employment Period and any extension or renewal thereof shall be referred to herein together as the “Employment Period”. Notwithstanding anything to the contrary contained herein, the Employment Period is subject to termination pursuant to
Article 4 hereof. 
 ARTICLE 3 
 COMPENSATION AND BENEFITS 
 3.1 Base Salary. During the Employment
Period, the Company will pay Employee an annual base salary at a rate of $285,000.00 per annum (the “Base Salary”), payable in accordance with the Company’s regular payroll policy for salaried employees. The Base Salary of Employee
may be subject to periodic review and adjustment by the Company during the Employment Period. If the Employment Period is terminated pursuant to Article 4 hereof or is otherwise shorter than a full contract year, then the Base Salary for any partial
year will be prorated based on the number of days elapsed in such year during which services were actually performed by Employee. 
 3.2 Benefits. 
 a. From the Effective Date until the Spin-Off is complete, during the Employment
Period, Employee will be entitled to participate in the group health insurance and other benefits offered by PPDI and available to Company employees, subject to Employee meeting the eligibility requirements for such PPDI plans and benefits. After
the Spin-Off, during the Employment Period, Employee will no longer be entitled to participate in the PPDI plans and benefits, but will be entitled to participate in the Company’s plans and benefits as such plans and benefits are maintained
from time to time by the Company, subject again to Employee meeting the applicable eligibility criteria therefor. Nothing in this Agreement will be interpreted to alter PPDI’s or the Company’s right to amend, modify or terminate any such
plans and benefits in its

  

 2 

 
discretion from time to time. During the Employment Period, Employee will also be entitled to twenty-seven (27) days of paid time off, subject to the provisions of the Company’s
Handbook or any other written policy of the Company on paid time off. 
 b. In addition to the benefits provided
in (a), above, during the Employment Period, Employee will be eligible to participate in the Company’s discretionary annual cash incentive plan (the “Cash Incentive Plan”), once adopted and established by the Board of Directors of the
Company (the “Board”) or a committee thereof. Subject to the Company establishing and implementing the Cash Incentive Plan, the Company anticipates that the target bonus for Employee’s position in 2010 will be thirty percent
(30%) of Employee’s Base Salary earned in that calendar year. Awards under the Cash Incentive Plan, if any, will be based upon both the Company’s achievement of its corporate and financial goals and Employee’s individual
performance, and are entirely at the Company’s discretion. To receive any award under the Cash Incentive Plan, Employee must be actively employed by the Company on the date payments are made under the Cash Incentive Plan. 
 3.3 Equity Compensation. Subject to the adoption of an equity compensation plan by the Company’s Board (the “Equity
Plan”), Employee shall be eligible to participate in such Plan during the Employment Period. Subject to the approval by the Company’s Board or committee thereof, the Company shall grant to Employee non-qualified options to purchase shares
of the Company’s common stock on or before the expiration of the 60-day period following the Spin-Off (the “Initial Option Grant”). The Initial Option Grant shall be subject to the terms and conditions of the Equity Plan and such
other stock option award agreements and/or terms and conditions as the Company’s Board shall require. In addition, the Initial Option Grant shall be subject to a vesting schedule to be established by the Company’s Board and shall have an
exercise price based on the fair market value of the Company’s common stock on the date of grant. 
 3.4 Expenses.
During the Employment Period, the Company will reimburse Employee, in accordance with and subject to Employee’s compliance with the Company’s policy, for Employee’s necessary and reasonable out-of-pocket expenses incurred in the
course of performance of Employee’s duties hereunder. All reimbursement of expenses to Employee hereunder shall be conditioned upon Employee’s presentation of timely and sufficient documentation evidencing such expenses, in accordance with
the Company’s policies and procedures on business expense reimbursement. 
 3.5 Working Facilities. Employee shall
work out of the Company’s offices in Wilmington, North Carolina. The Company shall furnish Employee with such office space, equipment, technical, secretarial and clerical assistance and such other facilities, services and supplies as shall be
reasonably necessary to enable Employee to perform the duties required of Employee hereunder in an efficient and professional manner.

 4.2 Compensation After Termination During Employment Period. If the Company
terminates Employee’s employment during the Employment Period pursuant to Section 4.1 hereof or if either party terminates this Agreement pursuant to Article 2 hereof, then the Company shall have no further obligations hereunder or
otherwise with respect to Employee’s employment from and after the termination or expiration date, except that the Company shall pay Employee’s Base Salary accrued through the date of termination or expiration and shall provide such
benefits as are required by applicable law. From and after such termination or expiration date, the Company shall continue to have all other rights available hereunder, including without limitation all rights under the Proprietary Agreement and/or

 PROPRIETARY INFORMATION 
 AND INVENTIONS AGREEMENT

 In consideration and as a condition of my employment by PPD Therapeutics, Inc., a Delaware corporation with its principal
place of business in Wake County, North Carolina, or any affiliate, subsidiary, successor or assigns, as the case may be (collectively referred to herein as the “Company”), I hereby agree as follows: 
 1. “Proprietary Information” is information that was or is developed by, became or becomes known by, or was or is assigned or
otherwise conveyed to the Company, and which has commercial value in the Company’s business. Proprietary Information includes, without limitation, trade secrets, financial information, product plans, customer lists, marketing plans and

of the Company or its customers or clients which I have been, or may be exposed to, or have learned or may learn of from time to time in connection with or as a result of my capacity as an employee of or consultant to the Company, including during
the term of this Agreement. Proprietary Information shall not include information that is, through no improper action or inaction by me, generally available to the public. I understand that my employment creates a relationship of confidence and
trust between me and the Company with respect to Proprietary Information of the Company or its customers which may be learned by me during the period of my employment. 
 2. In consideration of my employment by the Company and the compensation received by me from the Company from time to time, I hereby agree as follows: 
 (a) All Proprietary Information and all patents, copyrights, trade secret rights and other rights (including throughout,
without limitation, any extensions, renewals, continuations or divisions of any of the foregoing) in connection therewith shall be the sole property of the Company. I hereby assign to the Company any rights I may have or acquire in such Proprietary
Information. At all times, both during my employment by the Company and after its termination, I will keep in confidence and trust and will not use or disclose any Proprietary Information or anything relating to it without the written consent of the
Company, except as may be necessary in the ordinary course of performing my duties to the Company. 

 (b) In the event of the termination of my employment by me or by the Company
for any reason, I shall return all documents, records, apparatus, equipment and other physical property, or any reproduction of such property, whether or not pertaining to Proprietary Information, furnished to me by the Company or produced by myself
or others in connection with my employment, to the Company immediately as and when requested by the Company. 
 (c) I will promptly disclose to the Company, or any persons designated by it, all “Inventions”, which includes all improvements, inventions, formulas, ideas, works of authorship, processes, computer programs and software, software
designs and documentation, algorithms, techniques, schematics, know-how data, whether or not patentable, made or conceived or reduced to practice or developed by me, either alone or jointly with others, during the term of my employment and for six
(6) months thereafter. To the extent the Company does not have rights therein hereunder, such disclosure shall be received by the Company in confidence and does not extend the assignment made in Section (d) below. 
 (d) I agree that all Inventions which I make, conceive, reduce to practice or develop (in whole or in part, either alone or
jointly with others) during my employment shall be the sole property of the Company to the maximum extent permitted by law, and, to the extent permitted by law, shall be “works made for hire”. The Company shall be the sole owner of all
patents, copyrights, trade secret rights, and other intellectual property or other rights in connection therewith. I hereby assign to the Company any rights I may have or acquire in such Inventions. I agree to perform, during and after my

signing this Agreement. I understand that any such list shall not contain information that breaches an obligation of confidentiality with a former employer. 
 (f) I represent that my performance of all the terms of this Agreement will not breach any agreement or obligation to keep in
confidence proprietary information acquired by me in confidence or in trust prior to my employment by the Company. I have not entered into, and I agree I will not enter into, any agreement either written or oral in conflict herewith or in conflict

 ANNEX B 
 NON-COMPETITION AND 
 NON-SOLICITATION AGREEMENT 

 THIS AGREEMENT is made this              day of
                    , 20    , by and between PPD Therapeutics, Inc., a Delaware corporation with its principal
place in North Carolina (the “Company”), and Paul S. Covington, MD, an individual whose address is 3116 Braemar Lane, Wilmington, NC 28409 (herein referred to as “Employee”). 
 RECITALS 
 A. The Company is engaged in the business of developing and commercializing, directly and with third parties, potential drug candidates and drug products in various therapeutic areas (the “Business”). 
 B. Employee will perform a highly responsible role in the Company’s organization, have specialized knowledge of the Company’s
Business, existing and future potential drug candidates and drug products, and trade secrets and proprietary information, and have contact with or knowledge of the Company’s employees and contractors. 
 C. The Company and Employee agree that because of the knowledge, information and relationships to which Employee will be exposed during the
course of Employee’s employment with the Company, it would be harmful to the Company for Employee to compete with the Company or solicit its employees or contractors in the manner prohibited by this Agreement and that the Company has a
legitimate business interest in protecting itself from such competition and solicitation. 
 NOW, THEREFORE, in consideration of
the foregoing and the mutual promises herein contained and other valuable consideration detailed below, the parties agree as follows: 
 1. Restrictive Covenants. In order to protect, among other things, the Company’s business interests, its investments in its drug candidates, drug products, trade secrets and proprietary information, its relationships with its
employees and contractors, and its goodwill, Employee agrees to the following covenants and restrictions: 
 1.1
Non-Competition Agreement. During employment with the Company and for a period of [*] after termination of employment with the Company (the “Non-Compete Restricted Period”), Employee will not, directly or indirectly, participate or
engage in any business or activity that competes with the Business of the Company in 
 [*] Confidential treatment requested; certain
information omitted and filed separately with the SEC. 

 the Territory (as defined below) in any capacity whatsoever, whether as an individual on his
or her own account or as an employee, consultant, contractor, officer, director, shareholder, partner, member, joint venturer, representative, agent or equity owner of any business entity. Notwithstanding the foregoing, nothing in this Agreement is
intended to prohibit Employee from: 
 (a) being employed by or providing any services to a pharmaceutical,
biotechnology, medical device or other business entity so long as Employee does not perform any work or consulting services for any such entity that, directly or indirectly, relates to any drug candidates or drug products that compete with any drug
candidates or drug products that are then being, or are proposed to be, developed, produced, manufactured, commercialized, provided or marketed by, under or through the Company, any collaborator or licensee of the Company, or other third party under
or pursuant to any agreement or arrangement with the Company, or its or their successors or assigns; or 
 (b)
passively owning two percent (2%) or less of the outstanding equity interests of any privately- or publicly-held entity. 
 1.2 Non-Solicitation of Employees. During employment with the Company and for a period of [*] after termination of employment with the Company (the “Non-Solicit Restricted Period”),
Employee also will not, directly or indirectly, in any manner, (a) solicit, hire, or offer to hire any employee or contractor of the Company while that person is employed or engaged by the Company and for three (3) months after the
termination of that person’s employment or engagement with the Company, or (b) otherwise encourage or induce any such employee or contractor to discontinue his or her relationship with the Company. 
 1.3 Nondisparagement. During and at all times after employment with the Company, Employee further agrees not to make
disparaging statements, remarks or rumors about the Company, its parent company, officers, directors, shareholders, employees, contractors, and/or other representatives or the Company’s Business to any third parties; provided, however,
that nothing in this Agreement is intended to prohibit Employee from responding in a truthful and appropriate manner in any legal process or to give truthful and appropriate testimony in a legal proceeding. 
 2. Consideration. The Company and Employee acknowledge that Employee has received good and valuable consideration for Employee’s
commitment to be bound by the restrictions set forth in this Agreement, which consideration includes, but is not limited to Employee’s initial employment with the Company and all of the compensation and other benefits therewith. 
 3. Territory. The restrictions contained in Section 1.1 of this Agreement apply to the following geographic regions:
(a) worldwide, in all areas of the world in which the Company conducts or engages in the Business; (b) or, if the foregoing territory 
 [*] Confidential treatment requested; certain information omitted and filed separately with the SEC. 
  

 2 

 is deemed too broad, then all areas of the Americas, Europe and Asia in which the Company conducts or
engages in the Business; (c) or, if the foregoing territory is deemed too broad, then all areas of the Americas and Europe in which the Company conducts or engages in the Business; (d) or, if the foregoing territory is deemed too broad,
then all areas in the Americas in which the Company conducts or engages in the Business; (e) or, if the foregoing territory is deemed too broad, then all areas in North America in which the Company conducts or engages in the Business;
(f) or, if the foregoing territory is deemed to broad, then all areas in the United States in which the Company conducts or engages in the Business; (g) or, if the foregoing territory is deemed to broad, then all areas in each state of the
United States in which the Company conducts or engages in the Business; (h) or, if the foregoing territory is deemed to broad, then each county, parish or other similar locality of each state in the United States in which the Company conducts
or engages in the Business (herein, the “Territory”). Employee acknowledges that, because the Company engages in the Business worldwide and because Employee could compete with the Company from anywhere in the world, the Territory must be
so broadly defined. 
 4. Remedies; Extension of Restricted Periods. Employee acknowledges and agrees that the covenants
set forth in this Agreement are reasonable and necessary for the protection of the Company’s legitimate business interests, that irreparable injury will result to the Company if Employee breaches any of the terms of this Agreement and that, in
the event Employee breaches or threatens to breach any provision of this Agreement, the Company will have no adequate remedy at law. Employee accordingly agrees that in the event Employee breaches or threatens to breach any of the covenants set
forth herein, the Company shall be entitled to immediate, temporary and permanent injunctive or other equitable relief without bond and without the necessity of showing actual money damages, subject to a hearing as soon as possible. Employee further
agrees that the Company shall also be entitled to pursue, separately or concurrently, any other remedies available for such breach by Employee, including the recovery of any damages it is able to prove. Employee further agrees that the Non-Compete
Restricted Period and the Non-Solicit Restricted Period will each be extended for a period of time equal to any period during which Employee is in breach of Section 1.1 or Section 1.2 hereof, as the case may be, and/or any period of time
during which Employee and the Company are engaged in litigation arising from or related to Sections 1.1 or 1.2 hereof, as the case may be. 
 5. Enforcement. Employee agrees that, if a court of competent jurisdiction determines, contrary to the Agreement of the parties, that any portion of this Agreement is unreasonable, invalid,
overbroad or unenforceable, the remainder of the Agreement shall be given full effect without regard to the invalid provisions and the Company may enforce the covenant as to any lesser portion of the activity, Non-Compete Restricted Period,
Non-Solicit Restricted Period and/or Territory that is deemed by the court to be reasonable and enforceable under applicable law. In this regard, the covenants shall be divisible as to activity, Non-Compete Restricted Period, Non-Solicit Restricted
Period and/or Territory, with each month deemed to be a separate period of time, and each state and country, or part thereof included in the Territory, deemed to be a separate geographic area. Employee further agrees that the Company may, at its
option, seek to enforce the covenant as to any lesser activity, Non-Compete Restricted Period, Non-Solicit Restricted Period and/or Territory that the Company deems appropriate. 
  

 3 

 6. Effect of Termination. Employee agrees that the terms of this Agreement shall be
enforceable against the Employee regardless of who terminates the employment relationship and regardless of the basis of Employee’s termination, whether voluntary or involuntary and with or without cause. Employee further agrees that the
existence of a claim by Employee against the Company, whether predicated on Employee’s termination, this Agreement or otherwise, shall not constitute a defense to enforcement of the restrictions contained herein. Notwithstanding the foregoing,
in the event the Company terminates Employee’s employment due to a reduction in force or layoff in connection with the discontinuation or cessation of a business line, unit, function or department, the Company shall not enforce Section 1.1
of the Agreement. 
 7. Notification. Employee authorizes the Company to notify others, including but not limited to any
future employer of Employee, about the existence and terms of this Agreement and Employee’s obligations hereunder. 
 8.
Jurisdiction and Venue. The parties agree that the federal or state courts sitting in Wake County, North Carolina, shall be the exclusive jurisdiction to enforce the covenants set forth in this Agreement and to resolve any disputes or
controversies arising out of or related to this Agreement. Employee consents to personal jurisdiction and venue in either of said courts, and waives any claims or defenses based on improper venue or jurisdiction. 
 9. Attorneys’ Fees and Costs. Employee agrees that, in the event Employee breaches or threatens to breach any of the provisions
of this Agreement, the Company shall be entitled to recover from Employee all expenses incurred by it in enforcing the terms of this Agreement, including, but not limited to, its reasonable attorneys’ fees and costs. 
 10. Governing Law. This Agreement shall be construed and enforced in accordance with the laws of the State of North Carolina.

 Exhibit 10.19 
 Portions of this exhibit marked [*] are requested to be treated confidentially. 
 EMPLOYMENT AGREEMENT 
 THIS EMPLOYMENT AGREEMENT (the
“Agreement”), is made and entered into on this 29th day of January, 2010, to be effective on the 29th day of January, 2010 (the “Effective Date”), by and between PPD Therapeutics, Inc., a Delaware corporation (the “Company”), with its principal place of business in North
Carolina and currently with a mailing address for notice purposes of 929 North Front Street, Wilmington, North Carolina 28401, Attention: President, and Marshall Woodworth (“Employee”), an individual whose mailing address for notice
purposes is 503 Middenhall Way, Cary, North Carolina 27513. 
 RECITALS 
 A. Before Employee and the Company entered into this Agreement, Pharmaceutical Product Development, Inc. (“PPDI”) announced its
plan to spin off its compound partnering business into a separate, publicly-traded entity (the “Spin-Off”). 
 B. The
Company is a wholly-owned subsidiary of PPDI and was formed for the purpose of owning and operating PPDI’s compound partnering business prior to and after the Spin-Off. 
 C. PPDI and the Company currently anticipate that the Spin-Off will be accomplished through a pro rata dividend of all of the common stock
of the Company to the shareholders of PPDI and will be completed by mid-2010. 
 D. The Company desires to employ Employee and
Employee desires to be employed by the Company, all upon the terms and conditions set forth herein. 
 NOW, THEREFORE, in
consideration of the foregoing recitals, the mutual covenants of the parties hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

 ARTICLE 1 
 EMPLOYMENT AND DUTIES 
 1.1 Employment of Employee. On the Effective Date, the Company agrees to employ
Employee and Employee accepts such employment pursuant and subject to the terms and conditions of this Agreement. 
 1.2.
Duties and Powers. During the Employment Period (as defined herein), Employee shall serve as Vice President-Finance of the Company and Company’s principal financial officer for purposes of Securities and Exchange Commission reporting and
will have such responsibilities, duties and authority, and will render such services for and in connection with the Company and its affiliates as are customarily performed by the head financial officer of a publicly-traded company and as the Board
of Directors of the

 
Company (the “Board”) and the President of the Company shall from time to time reasonably direct. Employee shall devote Employee’s full business time and attention exclusively to
the Business of the Company and shall use best efforts to faithfully carry out Employee’s duties and responsibilities hereunder. Employee shall comply with all personnel policies and procedures of the Company as the same now exist or may be
hereafter implemented by the Company from time to time, including those policies contained in the Company’s employee manual or handbook which sets forth policies and procedures generally for employees of the Company and its current or future
subsidiaries (the “Handbook”) to the extent not inconsistent with this Agreement. 
 ARTICLE 2 
 TERM OF EMPLOYMENT 
 Unless sooner terminated as provided elsewhere in this Agreement, Employee’s employment under this Agreement shall begin the Effective Date and end on the first anniversary thereof (“Initial Employment Period”). After the
Initial Employment Period, this Agreement shall automatically renew for successive one-year periods, unless either the Company or Employee provides written notice to the other at least ninety (90) days prior to the termination of the Initial
Employment Period or any renewal period stating said party’s desire to terminate this Agreement. The Initial Employment Period and any extension or renewal thereof shall be referred to herein together as the “Employment Period”.
Notwithstanding anything to the contrary contained herein, the Employment Period is subject to termination pursuant to Article 4 hereof. 
 ARTICLE 3 
 COMPENSATION AND BENEFITS 
 3.1 Base Salary. During the Employment Period, the Company will pay Employee an annual base salary at a rate of $220,000 per annum
(the “Base Salary”), payable in accordance with the Company’s regular payroll policy for salaried employees. The Base Salary of Employee may be subject to periodic review and adjustment by the Company during the Employment Period. If
the Employment Period is terminated pursuant to Article 4 hereof or is otherwise shorter than a full contract year, then the Base Salary for any partial year will be prorated based on the number of days elapsed in such year during which services
were actually performed by Employee. 
 3.2 Benefits. 
 a. From the Effective Date until the Spin-Off is complete, during the Employment Period, Employee will be entitled to
participate in the group health insurance and other benefits offered by PPDI and available to Company employees, subject to Employee meeting the eligibility requirements for such PPDI plans and benefits. After the Spin-Off, during the Employment
Period, Employee will no longer be entitled to participate in the PPDI plans and benefits, but will be entitled to participate in the Company’s plans and benefits as such plans and benefits are maintained from time to time by the Company,
subject again to Employee meeting the applicable eligibility criteria therefor. Nothing in this Agreement will be interpreted to alter PPDI’s or the

  

 2 

 
Company’s right to amend, modify or terminate any such plans and benefits in its discretion from time to time. During the Employment Period, Employee will also be entitled to twenty-two
(22) days of paid time off, subject to the provisions of the Company’s Handbook or any other written policy of the Company on paid time off. 
 b. In addition to the benefits provided in (a), above, during the Employment Period, Employee will be eligible to participate in the Company’s discretionary annual cash incentive plan (the “Cash
Incentive Plan”), once adopted and established by the Company’s Board or a committee thereof. Subject to the Company establishing and implementing the Cash Incentive Plan, the Company anticipates that the target bonus for Employee’s
position in 2010 will be thirty percent (30%) of Employee’s Base Salary earned in that calendar year. Awards under the Cash Incentive Plan, if any, will be based upon both the Company’s achievement of its corporate and financial goals
and Employee’s individual performance, and are entirely at the Company’s discretion. To receive any award under the Cash Incentive Plan, Employee must be actively employed by the Company on the date payments are made under the Cash
Incentive Plan. 
 3.3 Equity Compensation. Subject to the adoption of an equity compensation plan by the Company’s
Board (the “Equity Plan”), Employee shall be eligible to participate in such Plan during the Employment Period. Subject to the approval by the Company’s Board or committee thereof, the Company shall grant to Employee incentive options
to purchase shares equal to 0.25% of the Company’s outstanding common stock on or before the expiration of the sixty (60) day period following the Spin-Off (the “Initial Option Grant”). The Initial Option Grant shall be subject
to the terms and conditions of the Equity Plan and such other stock option award agreements and/or terms and conditions as the Company’s Board shall require. In addition, the Initial Option Grant shall be subject to a three year linear vesting
schedule under which one-third of the total number of options granted under the Initial Option Grant shall vest on the first, second and third anniversaries of the Effective Date. The Initial Option Grant shall have an exercise price based on the
fair market value of the Company’s common stock on the date of grant as measured in the manner established by the Company’s Board or committee thereof. 
 3.4 Expenses. During the Employment Period, the Company will reimburse Employee, in accordance with and subject to Employee’s compliance with the Company’s policy, for Employee’s
necessary and reasonable out-of-pocket expenses incurred in the course of performance of Employee’s duties hereunder. All reimbursement of expenses to Employee hereunder shall be conditioned upon Employee’s presentation of timely and
sufficient documentation evidencing such expenses, in accordance with the Company’s policies and procedures on business expense reimbursement. 
 3.5 Working Facilities. Employee shall work out of the Company’s principal offices in Morrisville, North Carolina. The Company shall furnish Employee with such office space, equipment,
technical, secretarial and clerical assistance and such other facilities, services and supplies as shall be reasonably necessary to enable Employee to perform the duties required of Employee hereunder in an efficient and professional manner.

 ANNEX B 
 NON-COMPETITION AND 
 NON-SOLICITATION AGREEMENT 

 THIS AGREEMENT is made this          day of
                    , 2010, by and between PPD Therapeutics, Inc., a Delaware corporation with its principal place in North Carolina (the
“Company”), and Marshall Woodworth, an individual whose address is 503 Middenhall Way, Cary, North Carolina 27513 (herein referred to as “Employee”). 
 RECITALS 
 A. The Company is engaged in the business of developing and
commercializing, directly and with third parties, potential drug candidates and drug products in various therapeutic areas (the “Business”).

products, and trade secrets and proprietary information, and have contact with or knowledge of the Company’s employees and contractors. 
 C. The Company and Employee agree that because of the knowledge, information and relationships to which Employee will be exposed during the course of Employee’s employment with the Company, it would
be harmful to the Company for Employee to compete with the Company or solicit its employees or contractors in the manner prohibited by this Agreement and that the Company has a legitimate business interest in protecting itself from such competition
and solicitation. 
 NOW, THEREFORE, in consideration of the foregoing and the mutual promises herein contained and other
valuable consideration detailed below, the parties agree as follows:

 [*] Confidential treatment requested; certain information omitted and filed separately with the SEC.

 
shareholder, partner, member, joint venturer, representative, agent or equity owner of any business entity. Notwithstanding the foregoing, nothing in this Agreement is intended to prohibit
Employee from: 
 (a) being employed by or providing any services to a pharmaceutical, biotechnology, medical
device or other business entity so long as Employee does not perform any work or consulting services for any such entity that, directly or indirectly, relates to any drug candidates or drug products that compete with any drug candidates or drug
products that are then being, or are proposed to be, developed, produced, manufactured, commercialized, provided or marketed by, under or through the Company, any collaborator or licensee of the Company, or other third party under or pursuant to any
agreement or arrangement with the Company, or its or their successors or assigns; or 
 (b) passively owning two

manner, (a) solicit, hire, or offer to hire any employee or contractor of the Company while that person is employed or engaged by the Company and for three (3) months after the termination of that person’s employment or engagement
with the Company, or (b) otherwise encourage or induce any such employee or contractor to discontinue his or her relationship with the Company. 
 1.3 Nondisparagement. During and at all times after employment with the Company, Employee further agrees not to make disparaging statements, remarks or rumors about the Company, its parent company,
officers, directors, shareholders, employees, contractors, and/or other representatives or the Company’s Business to any third parties; provided, however, that nothing in this Agreement is intended to prohibit Employee from responding in
a truthful and appropriate manner in any legal process or to give truthful and appropriate testimony in a legal proceeding. 
 2. Consideration. The Company and Employee acknowledge that Employee has received good and valuable consideration for Employee’s commitment to be bound by the restrictions set forth in this Agreement, which consideration
includes, but is not limited to Employee’s initial employment with the Company and all of the compensation and other benefits therewith.

(herein, the “Territory”). Employee acknowledges that, because the Company engages in the Business worldwide and because Employee could compete with the Company from anywhere in the world, the Territory must be so broadly defined.

 4. Remedies; Extension of Restricted Periods. Employee acknowledges and agrees that the covenants set forth in this
Agreement are reasonable and necessary for the protection of the Company’s legitimate business interests, that irreparable injury will result to the Company if Employee breaches any of the terms of this Agreement and that, in the event Employee
breaches or threatens to breach any provision of this Agreement, the Company will have no adequate remedy at law. Employee accordingly agrees that in the event Employee breaches or threatens to breach any of the covenants set forth herein, the
Company shall be entitled to immediate, temporary and permanent injunctive or other equitable relief without bond and without the necessity of showing actual money damages, subject to a hearing as soon as possible. Employee further agrees that the
Company shall also be entitled to pursue, separately or concurrently, any other remedies available for such breach by Employee, including the recovery of any damages it is able to prove. Employee further agrees that the Non-Compete Restricted Period
and the Non-Solicit Restricted Period will each be extended for a period of time equal to any period during which Employee is in breach of Section 1.1 or Section 1.2 hereof, as the case may be, and/or any period of time during which
Employee and the Company are engaged in litigation arising from or related to Sections 1.1 or 1.2 hereof, as the case may be. 
 5. Enforcement. Employee agrees that, if a court of competent jurisdiction determines, contrary to the Agreement of the parties, that any portion of this Agreement is unreasonable, invalid, overbroad or unenforceable, the remainder
of the Agreement shall be given full effect without regard to the invalid provisions and the Company may enforce the covenant as to any lesser portion of the activity, Non-Compete Restricted Period, Non-Solicit Restricted Period and/or Territory
that is deemed by the court to be reasonable and enforceable under applicable law. In this regard, the covenants shall be divisible as to activity, Non-Compete Restricted Period, Non-Solicit Restricted Period and/or Territory, with each month deemed
to be a separate period of time, and each state and country, or part thereof included in the Territory, deemed to be a separate geographic area. Employee further agrees that the Company may, at its option, seek to enforce the covenant as to any
lesser activity, Non-Compete Restricted Period, Non-Solicit Restricted Period and/or Territory that the Company deems appropriate.

 6. Effect of Termination. Employee agrees that the terms of this Agreement shall be
enforceable against the Employee regardless of who terminates the employment relationship and regardless of the basis of Employee’s termination, whether voluntary or involuntary and with or without cause. Employee further agrees that the
existence of a claim by Employee against the Company, whether predicated on Employee’s termination, this Agreement or otherwise, shall not constitute a defense to enforcement of the restrictions contained herein. Notwithstanding the foregoing,
in the event the Company terminates Employee’s employment due to a reduction in force or layoff in connection with the discontinuation or cessation of a business line, unit, function or department, the Company shall not enforce Section 1.1
of the Agreement. 
 7. Notification. Employee authorizes the Company to notify others, including but not limited to any
future employer of Employee, about the existence and terms of this Agreement and Employee’s obligations hereunder. 
 8.
Jurisdiction and Venue. The parties agree that the federal or state courts sitting in Wake County, North Carolina, shall be the exclusive jurisdiction to enforce the covenants set forth in this Agreement and to resolve any disputes or
controversies arising out of or related to this Agreement. Employee consents to personal jurisdiction and venue in either of said courts, and waives any claims or defenses based on improper venue or jurisdiction. 
 9. Governing Law. This Agreement shall be construed and enforced in accordance with the laws of the State of North Carolina.

 10. Severability. The provisions of this Agreement as well as each paragraph and subparagraph hereof shall be deemed
severable, and if any provisions, paragraphs or subparagraphs hereof are held to be invalid or unenforceable by a court of competent jurisdiction, the remaining provisions, paragraphs and/or subparagraphs shall continue to be valid and enforceable.

 11. Modification. This Agreement cannot be altered, amended, or modified in any respect, except by a writing that
specifically refers to this Agreement and the amendment(s) thereto, duly executed by the parties. 
 12. Waiver. The
Company’s waiver of any violation of this Agreement or failure to enforce any provision of this Agreement shall not constitute a waiver of the Company’s rights with respect to other or future violations of this Agreement. Any waiver must
be in a writing signed by the Company and specifically refer to a waiver of provision(s) of this Agreement. 
 13. Binding
Effect. This Agreement shall be binding upon and inure to the benefit of the parties, their heirs, successors and assigns. 
 14. Entire Agreement. This Agreement contains the entire agreement of the parties with respect to the matters set forth herein and supercedes all previous negotiations and discussions, agreements and understandings regarding such
matters, with

the exception of Employee’s Proprietary Information and Inventions Agreement and any employment agreement to which Employee and the Company are parties. In the event of any conflict between
this Agreement and any other the Company agreements, the terms of the agreement which are most restrictive shall control. It is understood that this Agreement does not constitute an express or implied employment contract for any definite period of
time and that, absent a written agreement between the Company and Employee, Employee’s employment with the Company is “at will” meaning that either the Company or Employee can end the employment relationship at any time, with or
without cause. 
 15. Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of
which shall be deemed an original and all of which taken together shall constitute one and the same instrument. 
 IN WITNESS
WHEREOF, the parties have executed this Non-Competition and Non-Solicitation Agreement, effective as of the last date set forth below.
