 Exhibit 10.1 

RETENTION AGREEMENT 

This Retention Agreement (this “Agreement”) is made as of
[                ], 2016 (the “Effective Date”) by and between [NAME] (“Employee”) and INC Research Holdings, Inc. (together
with its affiliates, the “Company”).  
 WHEREAS Employee is currently an employee of the
Company; 
 WHEREAS the Company wishes to incentivize the Employee to remain employed with the Company through the
dates specified herein; and 
 WHEREAS Employee wishes to continue his employment with the Company consistent
with the terms set forth herein. 
 NOW THEREFORE, in consideration of the mutual promises and covenants contained in
this Agreement, Employee and the Company contract and agree as follows: 
 1.      Retention
Compensation. The Company will provide to Employee cash- and equity-based retention compensation as described below. 

(a)      Cash Retention Bonus. Employee will be eligible to receive a cash retention
bonus of up to [$                    ] (the “Retention Bonus”), subject to the terms below. The Retention Bonus will be
earned if Employee remains employed by the Company through                     (“Payment Date”). The Retention Bonus earned will be
paid on the first regularly scheduled payday following the Payment Date, less all federal, state and local taxes that the Company reasonably determines are required to be withheld pursuant to applicable law. Except as described in Section 1(c)
below, if Employee fails to remain continuously employed by the Company through the Payment Date, Employee will not be entitled to receive the Retention Bonus. 

(b)      Restricted Stock Units. Subject to approval by the Company’s Board of
Directors, the Company will grant to Employee [            ] restricted stock units (the “RSUs”). The RSUs will vest in equal annual installments of
        % of the RSUs over a       -year period on each anniversary of the date of grant , subject to Employee’s continued employment with the Company through
each such vesting date. The RSUs will be subject to the terms of the Company’s 2014 Equity Incentive Plan and a related restricted stock unit award agreement to be entered between Employee and the Company. 

(c)      Effect of Termination without Cause. If the Company terminates Employee’s
employment without Cause (as defined below), then (i) to the extent not previously paid, the Retention Bonus will be deemed earned by Employee and will be paid on the first regularly scheduled payday following the termination of Employee’s
employment, less all federal, state and local taxes that the Company reasonably determines are required to be withheld pursuant to applicable law, and (ii) to the extent not previously vested, the RSUs will immediately vest in full. 

  
 - 1 - 

 (d)      Effect of Certain Leaves of
Absence. An approved leave of absence for military service or sickness, or for any other purpose approved by the Company, will not be deemed to be a termination of employment if the Employee’s right to re-employment is guaranteed either by
statute, by contract, or under the policy pursuant to which the leave of absence was granted. In addition, in the event that such leave of absence exceeds three (3) months, then to the extent permitted by law, the dates for payment of the
Retention Bonus and vesting of the RSUs (to the extent not previously paid or vested) will be extended by the length of such leave of absence. 

2.      Cause. As used herein, “Cause” means: (a) if Employee has a then-effective
employment agreement with the Company that defines “Cause” or a like term, the meaning set forth in such agreement at the time of the Employee’s termination of employment, or (b) in the absence of such an agreement or definition:
(i) Employee’s fraud, embezzlement, misappropriation, or act(s) of dishonesty with respect to the Company; (ii) Employee’s breach of any fiduciary duty or legal or contractual obligation to the Company; (iii) Employee’s
failure to follow the reasonable instructions of Employee’s direct supervisor, which failure, if curable, is not cured within ten (10) business days or, if cured, recurs within one-hundred and eighty (180) calendar days;
(iv) Employee’s willful or negligent misconduct that has or may reasonably be expected to have a material adverse effect on the property, business, or reputation of the Company; (v) Employee’s conviction or plea of nolo
contendere in respect of any felony, or of a misdemeanor solely relating to the Company. 
 3.      No
Right to Continued Service. Nothing in this Agreement confers upon the Employee any right to continue in employment for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company or of the
Employee, which rights are hereby expressly reserved by each, to terminate his or her employment at any time and for any reason, with or without Cause, subject to applicable law. 

4.      Application of Section 409A. The parties intend that this Agreement and the payments and
benefits provided hereunder will comply with, or be exempt from, the application of Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations and other guidance thereunder and any state law of similar effect
(collectively, “Section 409A”), and all provisions of this Agreement will be construed, to the maximum extent possible, in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A. To the
extent any payment hereunder due upon the occurrence of Employee’s termination of employment constitutes deferred compensation that is subject to Section 409A, and is not otherwise exempt from complying with the provisions of
Section 409A, then such payment(s) will not commence unless and until Employee has also incurred a “separation from service” as such term is defined in Treasury Regulation Section 1.409A-1(h). If the Company determines that to
the extent any payment hereunder constitutes “deferred compensation” under Section 409A and the Employee is, on the termination of his or her employment, a “specified employee” of the Company or any successor entity thereto,
as such term is defined in Section 409A, then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the timing of such payment will be delayed until the earlier to occur of:
(i) the date that is six months and one day after Employee’s separation from service, or (ii) the date of Employee’s death (such applicable date, the “Specified Employee Initial Payment Date”), and the Company
(or the successor entity thereto, as applicable) will (A) pay to Employee a lump sum amount equal to the sum of the payments that Employee would otherwise have received through the Specified Employee Initial Payment Date if the commencement of
the payment of the payments had not been so delayed pursuant to this Section, and (B) commence paying the balance (if any) of any such payments in accordance with the applicable payment schedules set forth in this Agreement. Each installment of
any payments provided for in this Agreement is a separate “payment” for purposes of Section 409A.

	5.	 Miscellaneous Provisions. 

(a)      Governing Law. This Agreement will be governed by the laws of the State of North
Carolina without giving effect to the choice or conflict of law principles of any jurisdiction. 

(b)      Jurisdiction; Venue. Employee and the Company agree that any litigation arising
out of or related to this Agreement will be brought exclusively in any state or federal court in Wake County, North Carolina. Each party (i) consents to the personal jurisdiction of such courts, (ii) waives any venue or inconvenient forum
defense to any proceeding maintained in such courts, and (iii) agrees not to bring any proceeding arising out of or relating to this Agreement in any other court.

she is entering into this agreement voluntarily, has carefully read this entire Agreement, and understands and is fully aware of its contents and of its legal effect.

convenience only and are not intended to affect the interpretation of this Agreement. The word “including” in this Agreement means “including without limitation.” This Agreement will be construed as if drafted jointly by the

or number as the circumstances require. 
 (e)      Entire Agreement. This writing
represents the entire agreement and understanding of the parties with respect to the subject matter hereof and supersedes any prior negotiations, discussions, understandings, or agreements related to such subject matter. 

(f)      Amendments and Waivers. This Agreement may not be altered or amended except by

parties.

inure to the benefit of the parties hereto and the respective heirs, executors, administrators, personal representatives, successors, and assigns of the parties. Employee may not assign, delegate or otherwise transfer any of Employee’s rights,
interests or obligations in this Agreement without the prior written approval of the Company.

 ARTICLE VI 

FEDERAL EXCISE TAX UNDER SECTION 4999 OF THE CODE 

Section 6.01 In the event that the benefits provided for in this Plan (together with any other benefits or amounts)
otherwise constitute “parachute payments” within the meaning of Section 280G of the Code and would, but for this Article VI be subject to the Excise Tax, then the Participant’s benefits under this Plan shall be either: (i) delivered
in full, or (ii) delivered as to such lesser extent as would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the
Excise Tax, results in the receipt by the Participant on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. In the event of a
reduction of benefits hereunder, the Accountants (as defined below) shall determine which benefits shall be reduced so as to achieve the principle set forth in the preceding sentence. In no event shall the foregoing be interpreted or
administered so as to result in an acceleration of payment or further deferral of payment of any amounts (whether under this Plan or any other arrangement) in violation of Section 409A. 

Section 6.02 Unless the Company and the Participant otherwise agree in writing, all determinations required to be made
under this Article VI, including the manner and amount of any reduction in the Participant’s benefits under this Plan, and the assumptions to be utilized in arriving at such determinations, shall be promptly determined and reported in writing
to the Company and the Participant by Deloitte or such other independent public accountants or other independent advisors selected by the Company that are not serving as the accountants or auditors for the individual, entity or group effecting the
Change in Control (the “Accountants”), and all such computation and determinations shall be conclusive and binding upon the Participant and the Company. All fees and expenses of the Accountants shall be borne solely by the Company,
and the Company shall enter into any agreement requested by the Accountants in connection with the performance of the services hereunder. For purposes of making the calculations required by this Article VI, the Accountants may make reasonable
assumptions and approximations concerning the application of Sections 280G and 4999 of the Code. The Company and the Participant shall furnish to the Accountants such information and documents as the Accountants may reasonably request to make a
determination under this Article VI. 
 Section 6.03 As expressly permitted by Q/A #32 of the Treasury Regulations
under Code Section 280G, with respect to performing any present value calculations that are required in connection with this Article VI, the Participant and the Company each affirmatively elect to utilize the Applicable Federal Rates
(“AFR”) that are in effect as of the date this Plan is adopted and the Accountants shall therefore use such AFR in their determinations and calculations.

prescribe, amend and rescind rules and regulations under the Plan and make all other determinations necessary or advisable for the administration of the Plan, subject to all of the provisions of the Plan. The Plan Administrator is empowered, on
behalf of the Plan, to engage accountants, legal counsel and such other personnel as it deems necessary or advisable to assist it in the performance of its duties under the Plan. The functions of any such persons engaged by the Plan
Administrator will be limited to the specified services and duties for which they are engaged, and such persons will have no other duties, obligations or responsibilities under the Plan. Such persons will exercise no discretionary authority or

beneficiary or estate) hereunder all taxes which, by applicable federal, state, local or other law, the Company is required to withhold therefrom. 

Section 7.03 Scope of Benefits under Plan. Nothing in this Plan shall be deemed to entitle the Participant to
continued employment with the Company or its Affiliates; provided, however, that notwithstanding anything herein to the contrary, if the Participant is subject to a Qualifying Termination, the Participant shall be subject to all of the benefit and
payment provisions of this Plan. 
 Section 7.04 Successors’ Binding Obligation. 

(a)       This Plan shall not be terminated by any Company Change or transfer of assets. In
the event of any Company Change or transfer of assets, the provisions of this Plan shall be binding upon the surviving or resulting corporation or any person or entity to which the assets of the Company are transferred. 

(b)       The Company agrees that concurrently with any Company Change or transfer of assets, it

(c)       The rights under this Plan shall inure to the benefit of and be enforceable by the
Participant’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Participant shall die while any amounts would be payable to the Participant hereunder had the

Attention: Senior Vice-President, Human Resources 

or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of

Participant, as the case may be, to the other, shall (i) indicate the specific termination provision in this Plan relied upon, (ii) to the extent applicable, set forth in reasonable detail the facts and circumstances claimed to provide a basis for
termination of Participant’s employment under the provision so indicated and (iii) specify the Date of Termination. In the case of a termination by the Company other than a termination for Cause, the Date of Termination shall not be less
than 30 days after the notice of termination is given. In the case of a termination by the Participant, the Date of Termination shall be the date that the cure period contemplated under Section 1.01(u) has expired if the Company has failed to
remedy within such period the circumstances constituting Good Reason. The failure by the Participant or the Company to set forth in such notice any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any
right of the Participant or the Company hereunder or preclude the Participant or the Company from asserting such fact or circumstance in enforcing the Participant’s or the Company’s rights hereunder. 

Section 7.07 Employment with Affiliates. Employment with the Company for purposes of this Plan shall include
employment with any of its Affiliates.

 Section 7.08 Governing Law; Validity. The interpretation, construction
and performance of the provisions of this Plan shall be governed by and construed and enforced in accordance with the internal laws of the State of North Carolina without regard to the principle of conflicts of laws, to the extent North
Carolina laws are not preempted by ERISA. The invalidity or unenforceability of any provision of this Plan shall not affect the validity or enforceability of any other provision of this Plan, which other provisions shall remain in full force and
effect. 
 Section 7.09 Waiver. No provision of this Plan may be waived unless such waiver is agreed to in writing
and signed by the Participant and by a duly authorized officer of the Company. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Plan to be performed by
such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. Failure by the Participant or the Company to insist upon strict compliance with any provision of this
Participant or to assert any right the Participant or the Company may have hereunder, including without limitation, the right of the Participant to terminate employment for Good Reason, shall not be deemed to be a waiver of such provision or right
or any other provision or right of this Plan. 
 Section 7.10 Code Section 409A. It is intended that this Plan shall
be comply with the provisions of Section 409A of the Code, and the Plan shall be interpreted and administered in a manner consistent with this intent. The Company reserves the right, to the extent the Company deems necessary or advisable in its
sole discretion, to unilaterally amend or modify the Plan to ensure that all payments are made in a manner that complies with Section 409A of the Code (including, without limitation, the avoidance of penalties thereunder) to the extent permitted
under Section 409A of the Code; provided, however, that the Company makes no representations that the payments will be exempt from any penalties that may apply under Section 409A of the Code and makes no undertaking to preclude Section 409A of the
Code from applying to this Plan. Nothing in this Plan shall provide a basis for any person to take action against the Company or any affiliate thereof based on matters covered by Section 409A of the Code, including the tax treatment of any
amount paid under the Plan, and neither the Company nor any of its affiliates shall under any circumstances have any liability to the Participant or the Participant’s estate or any other party for any taxes, penalties or interest due on amounts
paid or payable under this Plan, including taxes, penalties or interest imposed under Section 409A of the Code. 

Section 7.11 No Right to Continued Employment. Neither the establishment of the Plan, nor any modification thereof,
nor the creation of any fund, trust or account, nor the payment of any benefits will be construed as giving any Participant, or any person whomsoever, the right to be retained in the service of the Company, and all Participants will remain subject
to discharge to the same extent as if the Plan had never been adopted.

 ARTICLE VIII 

CLAIMS, INQUIRIES, APPEALS

inquiries about present or future rights under the Plan must be submitted to the claims administrator in writing, as follows: 

Claims Administrator – Attn: Anne Tinker 

INC Research Holdings, Inc. 

3201 Beechleaf Court 

Raleigh, NC 27604 

Section 8.02 Denial of Claims. In the event that any application for benefits is denied in whole or in part, the
claims administrator must notify the applicant, in writing, of the denial of the application, and of the applicant’s right to review the denial. The written notice of denial will be set forth in a manner designed to be understood by the
Participant, and will include specific reasons for the denial, specific references to the Plan provision upon which the denial is based, a description of any information or material that the claims administrator needs to complete the review and an
explanation of the Plan’s review procedure. 
 This written notice will be given to the Participant within 30 days after the claims
administrator receives the application, unless special circumstances require an extension of time, in which case, the claims administrator has up to an additional 30 days for processing the application. If an extension of time for processing is
required, written notice of the extension will be furnished to the applicant before the end of the initial 30-day period. 
 This notice of
extension will describe the special circumstances necessitating the additional time and the date by which the claims administrator is to render his or her decision on the application. If written notice of denial of the application for benefits
is not furnished within the specified time, the application will be deemed to be denied. The applicant will then be permitted to appeal the denial in accordance with the review procedure described below. 

Section 8.03 Request for a Review. Any person (or that person’s authorized representative) for whom an
application for benefits is denied (or deemed denied), in whole or in part, may (but without any obligation to do so) appeal the denial by submitting a request for a review to the Plan Administrator within 60 days after the application is denied (or
deemed denied). The Plan Administrator will give the applicant (or his or her representative) an opportunity to review pertinent documents in preparing a request for a review and submit written comments, documents, records and other information
relating to the claim. A request for a review will be in writing and will be addressed to: 
 Claims Administrator
– Attn: Anne Tinker 
 INC Research Holdings, Inc. 

3201 Beechleaf Court 

Raleigh, NC 27604 

  
 12 

 A request for review must set forth all of the grounds on which it is based, all facts in support
of the request and any other matters that the applicant feels are pertinent. The Plan Administrator may require the applicant to submit additional facts, documents or other material as he or she may find necessary or appropriate in making his
or her review. 
 Section 8.04 Decision on Review. The Plan Administrator will act on each request for review within
20 days after receipt of the request, unless special circumstances require an extension of time (not to exceed an additional 20 days), for processing the request for a review. If an extension for review is required, written notice of the extension
will be furnished to the applicant within the initial 20-day period. The Plan Administrator will give prompt, written notice of his or her decision to the applicant. In the event that the Plan Administrator confirms the denial of the
application for benefits in whole or in part, the notice will outline, in a manner calculated to be understood by the applicant, the specific Plan provisions upon which the decision is based. If written notice of the Plan Administrator’s
decision is not given to the applicant within the time prescribed in this Section 8.04 the application will be deemed denied on review. 

Section 8.05 Rules and Procedures. The Plan Administrator may establish rules and procedures, consistent with the Plan
and with ERISA, as necessary and appropriate in carrying out his or her responsibilities in reviewing benefit claims. The Plan Administrator may require an applicant who wishes to submit additional information in connection with an appeal from
the denial (or deemed denial) of benefits to do so at the applicant’s own expense. 
 Section 8.06 Exhaustion
of Remedies. No claim for benefits under the Plan may be brought in any forum until the claimant (a) has submitted a written application for benefits in accordance with the procedures described by Section 8.01 above, (b) has been notified by the
claims administrator that the application is denied (or the application is deemed denied due to the claims administrator’s failure to act on it within the established time period), (c) has filed a written request for a review of the application
in accordance with the appeal procedure described in Section 8.03 above and (d) has been notified in writing that the Plan Administrator has denied the appeal (or the appeal is deemed to be denied due to the Plan Administrator’s failure to take
any action on the claim within the time prescribed by Section 8.04 above). 
 Section 8.07 Final Dispute Resolution.
Any and all disputes under this Plan (including but not limited to disputes regarding interpretation, scope, or validity of the Plan, any pendant state claims if not otherwise preempted by ERISA) remains unresolved after the exhaustion of the claims
procedure outlined in Sections 8.01 through 8.06, above, will be submitted to the exclusive jurisdiction of the United States District Court for the Eastern District of North Carolina. 

Section 8.08 Attorneys’ Fees. In the event of any dispute under this Plan, the court may award attorneys’
fees as provided under 29 U.S.C. 1132(g)(1).

Released Parties in any court of law or equity, or before any arbitral body or administrative agency, with respect to any matter released in Section 1.1 above; provided, however, that this covenant not to sue does not affect Your rights to enforce
appropriately the terms of the Severance Plan in a court of competent jurisdiction and does not affect Your right to file a charge with the EEOC or participate in an investigation conducted by the EEOC; however, You expressly waive Your right to

way be construed as an admission that any of the Released Parties owe You any money or have acted wrongfully, unlawfully, or unfairly in any way towards You. In fact, You understand that the Released Parties specifically deny that they have
violated any federal, state or local law or ordinance or any right or obligation that they owe or might have owed to You at any time, and maintain that they have at all times treated You in a fair, non-discriminatory and non-retaliatory manner.
