Schedule I hereto, with respect to Cinven MGP representing GPLP and the Limited Partnerships, Schedule II hereto, with respect to CIP (V) Nominees Limited representing CIP, and Schedule III hereto, with respect to Manco representing FCP, set forth a list of all the directors and executive officers or persons holding equivalent positions (collectively, the “Related Persons”) of each such Reporting Person and the citizenship and principal business address of each Related Person.

Shares beneficially owned by Dr. August J. Troendle are not the subject of this Schedule 13D and Dr. Troendle is accordingly not included as a Reporting Person. For a description of the relationship between the Reporting Persons and Dr. Troendle, see Item 4 below.

During the last five years, none of the Reporting Persons or Related Persons (i) has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

Prior to the Issuer’s initial public offering (the “IPO”), the Cinven Stockholders purchased shares of Common Stock for an aggregate consideration of approximately $921.3 million.

The Cinven Stockholders obtained the funds for the purchase of the shares of Common Stock through capital contributions from their partners and/or shareholders.

Item 4. Purpose of Transaction

Voting Agreement

On August 10, 2016, the Cinven Stockholders and Dr. August J. Troendle, the Chief Executive Officer of the Issuer, entered into a voting agreement (the “Voting Agreement”). Pursuant to the terms of the Voting Agreement, for so long as the Cinven Stockholders and Dr. Troendle collectively hold at least 40% of the Issuer’s outstanding shares of capital stock which entitle the holders thereof to vote for the election of the Issuer’s directors (the “Voting Shares”), and provided that Dr. Troendle remains the Chief Executive Officer of the Issuer, the Cinven Stockholders will agree to vote their shares of Common Stock in favor of the election of Dr. Troendle to the Issuer’s Board of Directors (the “Board”) upon his nomination by the Board. Moreover, Dr. Troendle will agree to vote his shares of Common Stock in favor of the election of the directors affiliated with the Cinven Stockholders upon their nomination by the Board; provided, that in the event that the Cinven Stockholders hold less than (a) 40% but greater than or equal to 25% of the Voting Shares then outstanding, Dr. Troendle shall be required to vote for two directors affiliated with the Cinven Stockholders, after giving effect to the directors then sitting on the Board, (b) 25% but greater than or equal to 10% of the Voting Shares then

outstanding, Dr. Troendle shall be required to vote for one director affiliated with the Cinven Stockholders, after giving effect to the directors then sitting on the Board, and (c) 10% of the Voting Shares then outstanding, Dr. Troendle shall not be required to vote for any directors affiliated with the Cinven Stockholders. The beneficial ownership of the Cinven Stockholders does not include any shares of Common Stock owned by Dr. Troendle, and each of the Cinven Stockholders disclaims beneficial ownership of the shares owned by the other parties to the Voting Agreement.

Registration Rights Agreement

On August 10, 2016, the Issuer, the Cinven Stockholders and Dr. Troendle entered into a registration rights agreement (the “Registration Rights Agreement”), pursuant to which the Issuer granted certain demand registration rights, shelf registration rights and piggyback registration rights to such shareholders. The rights of any shareholder under the Registration Rights Agreement will terminate upon the earlier to occur of: (i) all shares subject to the Registration Rights Agreement being registered pursuant to the terms of the Registration Rights Agreement or (ii) the parties to the Registration Rights Agreement becoming eligible to sell any shares subject to the Registration Rights Agreement pursuant to Rule 144 of the Securities Act of 1933, as amended.

Lock-Up Agreements

The Cinven Stockholders each entered into a letter agreement with the Issuer and the several underwriters for the IPO, on June 24, 2016 (collectively, the “Lock-Up Agreements”). Pursuant to such agreements, the Cinven Stockholders agreed, without the prior written consent of Jefferies LLC and subject to limited exceptions, not to: (i) sell, offer to sell, contract to sell or lend, effect any short sale or establish or increase a put equivalent position or liquidate or decrease any call equivalent position, pledge, hypothecate, grant any security interest in, transfer, or otherwise dispose of, in each case whether effected directly or indirectly, any shares of Common Stock, options or warrants or other rights to acquire shares of Common Stock, or securities exchangeable or exercisable for or convertible into shares of Common Stock, or to acquire other securities or rights ultimately exchangeable or exercisable for or convertible into shares of Common Stock owned either of record or beneficially; (ii) enter into any swap, hedge or similar arrangement or agreement that transfers, in whole or in part, the economic risk of ownership of shares of Common Stock or any options or warrants or other rights to acquire shares of Common Stock, or securities exchangeable or exercisable for or convertible into shares of Common Stock, or to acquire other securities or rights ultimately exchangeable or exercisable for or convertible into shares of Common Stock, regardless of whether any such transaction is to be settled in securities, in cash or otherwise; or (iii) publicly announce an intention to do any of the foregoing for a period of 180 days after the date of the prospectus used to sell the shares of Common Stock in the IPO. The Lock-Up Agreements automatically terminate and shall be of no further force or effect following the expiration of the Lock-Up Period.

The foregoing descriptions of the Voting Agreement, Registration Rights Agreement and the Lock-Up Agreements do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements filed as exhibits to this Schedule 13D, and incorporated herein by reference.

General

The Reporting Persons acquired the securities described in this Schedule 13D for investment purposes and they intend to review their investments in the Issuer on a continuing basis. Any actions the Reporting Persons might undertake will be dependent upon the Reporting Persons’ review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.

The Reporting Persons may, at any time and from time to time, acquire additional securities of the Issuer, or retain or sell all or a portion of the securities then held, in the open market or in privately negotiated transactions. In addition, the Reporting Persons or their designees to the Issuer’s board of directors may engage in discussions with management, the board of directors, and shareholders of the Issuer and other relevant parties or encourage such persons to consider or explore extraordinary corporate transactions, such as: a merger; sales or acquisitions of assets or businesses; changes to the capitalization or dividend policy of the Issuer; or other material changes to the Issuer’s business or corporate structure.

Other than as described above, none of the Reporting Persons currently has any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)–(j) of Schedule 13D, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.

(1) As discussed in Item 2 above, Dr. Troendle is not included as a Reporting Person in this Schedule 13D, and the Reporting Persons expressly disclaim beneficial ownership of the shares of Common Stock held by Dr. Troendle.

LP1, LP2, LP3, LP4, LP5 and LP6 are the record holders of 3,641,240, 3,229,699, 3,889,854, 3,379,103, 1,403,731 and 3,284,802 shares of Common Stock, respectively. CIP is the record holder of 413,399 shares of Common Stock. FCP is the record holder of 3,758,169 shares of Common Stock.

Each of the Limited Partnerships is managed and controlled by GPLP, their Managing General Partner, and therefore GPLP may be deemed to share beneficial ownership of the shares held by each of the Limited Partnerships. Cinven MGP is the Managing General Partner of GPLP, and therefore may be deemed to share beneficial ownership. FCP is managed by Manco. Cinven MGP also exercises control over the shares held by each of FCP and CIP, which are subject to contractual commitments that each invest and divest side-by-side with the Limited Partnerships. Voting and investment determinations with respect to the shares held by the Reporting Persons are made by the majority vote of the board of directors of Cinven MGP, whose members are listed on Schedule I.

Except as set forth in this Item 5(a)-(b), each of the persons named in this Item 5(a)-(b) disclaims beneficial ownership of any shares of Common Stock owned beneficially or of record by any other person named in this Item 5(a)-(b).

(c) During the past 60 days none of the Reporting Persons or Related Persons has effected any transactions in the Common Stock.

(d) None.

(e) Not Applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer

Item 4 above summarizes certain provisions of the Voting Agreement, Registration Rights Agreement and the Lock-Up Agreements and is incorporated herein by reference. A copy of each of these agreements is attached as an exhibit to this Schedule 13D, and incorporated herein by reference.

Except as set forth herein, none of the Reporting Persons or Related Persons has any contracts, arrangements, understandings or relationships (legal or otherwise) with any person with respect to any securities of the Issuer, including, but not limited to, any contracts, arrangements, understandings or relationships concerning the transfer or voting of such securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.

Requests for Registration. Subject to the terms and conditions of this Agreement, each Holder may request registration under the Securities Act of all or any portion of their Registrable Securities on Form S-1 or any similar long-form registration (“Long-Form Registrations”), and each Holder may request registration under the Securities Act of all or any portion of their Registrable Securities on Form S-3 or any similar short-form registration (“Short-Form Registrations”) if available. All registrations requested pursuant to this Section 2(a) are referred to herein as “Demand Registrations.” The Holder making a Demand Registration may request that the registration be made pursuant to Rule 415 under the Securities Act (a “Shelf Registration”) and, if the Company is a WKSI at the time any request for a Demand Registration is submitted to the Company, that such Shelf Registration be an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “Automatic Shelf Registration Statement”). Except to the extent that Section 2(c) applies, promptly upon receipt of a request for a Demand Registration (but in no event more than five Business Days thereafter), the Company shall give written notice of the Demand Registration to all other Holders. Notwithstanding the foregoing, other than delivery to each Holder of the written notice in accordance with this Section 2(a), the Company shall not be required to take any action that would otherwise be required under this Section 2 if such action would violate Section 4(a) hereof or any similar provision contained in the underwriting agreement entered into in connection with any underwritten Public Offering.

Demand Registrations. Each Holder shall be entitled to request an unlimited number of Demand Registrations in which the Company shall pay all Registration Expenses, regardless of whether any registration statement is filed or any such Demand Registration is consummated. Demand Registrations shall be Short-Form Registrations whenever the Company is permitted to use any applicable short form and the managing underwriters (if any) agree to the use of a Short-Form Registration. After the Company has become subject to the reporting requirements of the Exchange Act, the Company shall use its reasonable best efforts to make Short-Form Registrations available for the sale of Registrable Securities. All Long-Form Registrations shall be underwritten registrations unless otherwise approved by the applicable Holder.

Shelf Registrations.

Subject to the availability of required financial information, as promptly as practicable after the Company receives written notice of a request for a Shelf Registration from a Holder (a “Shelf Registration Request”) and the expiration of the Shelf Registration Participation Deadline (as defined below), the Company shall file with the Securities and Exchange Commission a registration statement under the Securities Act for the Shelf Registration (a “Shelf Registration Statement”). As promptly as practicable, but no later than two Business Days after receipt of a Shelf Registration Request, the Company shall give written notice (the “Shelf Registration Notice”) of such Shelf Registration Request to all other Holders. The Company, subject to Section 8 hereof, shall include in such Shelf Registration (and in all related registrations and qualifications under state blue sky laws) all Registrable Securities of each Holder with respect to which the Company has received a written request for inclusion therein within two Business Days after the Shelf Registration Notice was delivered (such deadline, the “Shelf Registration Participation Deadline”). The Company shall use its reasonable best efforts to cause any Shelf Registration Statement filed in accordance with this

5

Section 2(c)(i) to be declared effective under the Securities Act as soon as practicable after the initial filing of such Shelf Registration Statement and, once effective, the Company shall cause such Shelf Registration Statement to remain continuously effective for such time period as is specified in the request by the Holders, but for no time period longer than the period ending on the earliest of (A) the date on which all Registrable Securities covered by such Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement and (B) the date as of which there are no longer any Registrable Securities covered by such Shelf Registration Statement in existence.

Notwithstanding the rights of each Holder under Section 2(c)(i), subject to the availability of required financial information, as promptly as practicable after the Company becomes eligible to file a Shelf Registration Statement on Form S-3 the Company shall file with the Securities and Exchange Commission a Shelf Registration Statement on Form S-3 that includes in such Shelf Registration Statement (and in all related registrations and qualifications under state blue sky laws) all Registrable Securities held by each Holder. No later than five Business Days prior to the initial filing of the Shelf Registration Statement pursuant to this Section 2(c)(ii), the Company shall give written notice of such filing to each Holder (the “Shelf Registration Filing Notice”). Within two Business Days after the receipt of the Shelf Registration Filing Notice each holder shall send the Company a written notice specifying the number of Registrable Securities then held by each Holder or, at the option of such Holder, a lesser number of Registrable Securities to be included in such Shelf Registration Statement, as well as any additional information requested by the Company pursuant to Section 5(c). The Company shall use its reasonable best efforts to cause any Shelf Registration Statement filed in accordance with this Section 2(c)(ii) to be declared effective under the Securities Act as soon as practicable after the initial filing of such Shelf Registration Statement and, once effective, the Company shall cause such Shelf Registration Statement to remain continuously effective for such time period ending on the earliest of (A) the date on which all Registrable Securities covered by such Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement and (B) the date as of which there are no longer any Registrable Securities covered by such Shelf Registration Statement in existence.

In the event that a Shelf Registration Statement is effective, Holders representing Registrable Securities with a market value of at least $15 million (or such lesser amount if all Registrable Securities available for sale pursuant to such registration statement held by a Holder are requested to be included) shall have the right at any time or from time to time to elect to offer and sell (including pursuant to an underwritten offering (an “Underwritten Takedown”)) Registrable Securities available for sale pursuant to such Shelf Registration Statement (“Shelf Registrable Securities”), so long as the Shelf Registration Statement remains effective, and the Company shall pay all Registration Expenses in connection therewith. The applicable Holders shall make such election by delivering to the Company a written request (a “Shelf Offering Request”) for such offering specifying the number of Shelf Registrable Securities that such Holders desire to sell pursuant to such offering (the “Shelf Offering”). As promptly as practicable, but no later than two Business Days after receipt of a Shelf Offering Request, the Company shall give written notice (the “Shelf Offering Notice”) of such Shelf Offering Request to all

6

other holders of Shelf Registrable Securities. The Company shall, as expeditiously as possible (and in any event within 10 days after the receipt of a Shelf Offering Request, unless a longer period is agreed to by the Holders of the Registrable Securities that made the Shelf Offering Request), use its reasonable best efforts to facilitate such Shelf Offering.

The Company shall, at the request of any Holder of the Registrable Securities covered by a Shelf Registration Statement, file any prospectus supplement or, if the applicable Shelf Registration Statement is an Automatic Shelf Registration Statement, any post-effective amendments and otherwise take any action necessary to include therein all disclosure and language deemed necessary or advisable by such Holders to effect such Shelf Offering.

Restrictions on Demand Registration and Shelf Offerings.

Notwithstanding the foregoing, the Company shall not be obligated to effect any Demand Registration within 45 days after the consummation of another Demand Registration. Further notwithstanding the foregoing, the Company may postpone, for up to 90 days from the date of the request, the filing or the effectiveness of a registration statement for a Demand Registration or suspend the filing of a Shelf Registration Statement or the use of a prospectus that is part of a Shelf Registration Statement for up to 90 days from the date of the Suspension Notice (as defined below) and therefore suspend sales of the Shelf Registrable Securities (such period, the “Suspension Period”) by providing written notice to the Holders if (A) the Company’s board of directors determines in its reasonable good faith judgment that the offer or sale of Registrable Securities would reasonably be expected to have a material adverse effect on any proposal or plan by the Company or any Subsidiary to engage in any material acquisition of assets or stock (other than in the ordinary course of business) or any material merger, consolidation, tender offer, recapitalization, reorganization or other transaction involving the Company or any Subsidiary, or (B) upon advice of counsel, the sale of Registrable Securities pursuant to the registration statement would require disclosure of MNPI not otherwise required to be disclosed under applicable law, and either (x) the Company has a bona fide business purpose for preserving the confidentiality of such transaction or (y) disclosure of such MNPI would have a material adverse effect on the Company or the Company’s ability to consummate such transaction; provided that in such event, the Holders shall be entitled to withdraw such request for a Demand Registration or underwritten Shelf Offering and the Company shall pay all Registration Expenses in connection with such Demand Registration or Shelf Offering. The Company may delay a Demand Registration hereunder only once in any twelve-month period, except with the consent of the applicable Holder.

In the case of an event that causes the Company to suspend the filing or use of a Shelf Registration Statement as set forth in paragraph (d)(i) above or pursuant to applicable subsections of Section 5(a)(vi) (a “Suspension Event”), the Company shall give a notice to the Holders of Registrable Securities registered pursuant to such Shelf Registration Statement (a “Suspension Notice”) to suspend sales of the Registrable Securities and such notice shall state generally the basis for the notice and that such

7

suspension shall continue only for so long as the Suspension Event or its effect is continuing. If the basis of such suspension is nondisclosure of MNPI, the Company shall not be required to disclose the subject matter of such MNPI to Holders. A Holder shall not effect any sales of the Registrable Securities pursuant to such Shelf Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company and prior to receipt of an End of Suspension Notice (as defined below). Holders may recommence effecting sales of the Registrable Securities pursuant to the Shelf Registration Statement (or such filings) following written notice to such effect (an “End of Suspension Notice”) from the Company, which End of Suspension Notice shall be given by the Company to the Holders promptly following the conclusion of any Suspension Event.

Notwithstanding any provision herein to the contrary, if the Company gives a Suspension Notice with respect to any Shelf Registration Statement pursuant to this Section 2(d), the Company agrees that it shall provide copies of any supplemented or amended prospectus necessary to resume sales, with respect to each Suspension Event.

Selection of Underwriters. The Holder requesting the Demand Registration or Underwritten Takedown shall have the right to select the investment banker(s) and manager(s) to administer such offering (including assignment of titles), subject to the Company’s approval not be unreasonably withheld, conditioned or delayed.

Other Registration Rights. The Company represents and warrants that it is not a party to, or otherwise subject to, any other agreement granting registration rights to any other Person with respect to any securities of the Company. Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company or any Subsidiary to register any Capital Stock of the Company or of any Subsidiary, or any securities convertible or exchangeable into or exercisable for such securities.

Piggyback Registrations.

Right to Piggyback. Following the IPO, whenever the Company proposes to register any of its securities under the Securities Act (other than (i) pursuant to a Demand Registration, (ii) in connection with registrations on Form S-4 or S-8 promulgated by the Securities and Exchange Commission or any successor or similar forms or (iii) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of Registrable Securities) and the registration form to be used may be used for the registration of Registrable Securities (a “Piggyback Registration”), the Company shall give prompt written notice to all Holders of its intention to effect such Piggyback Registration and, subject to the terms of Section 3(c), shall include in such Piggyback Registration (and in all related registrations or qualifications under blue sky laws and in any related underwriting) all Registrable Securities of each Holder with respect to which the Company has received a written request for inclusion therein within 5 days after delivery of the Company’s notice.

8

Piggyback Expenses. The Registration Expenses of the Holders shall be paid by the Company in all Piggyback Registrations, whether or not any such registration became effective.

Priority on Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company shall include in such registration (i) first, the securities the Company proposes to sell, (ii) second, the Registrable Securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect, pro rata among the Holders on the basis of the number of Registrable Securities then owned by each such Holder that such Holder of Registrable Securities shall have requested to be included therein, and (iii) third, other securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect.

Selection of Underwriters. If any Piggyback Registration is an underwritten offering, the selection of investment banker(s) and manager(s) for the offering shall be at the election of the Company; provided that Holders representing a majority of the Registrable Securities included in such Piggyback Registration may request that one or more investment banker(s) or manager(s) be included in such offering (such request not to be binding on the Company or such other initiating holders of Company securities).

Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 3 whether or not any Holder has elected to include securities in such registration. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 6.

Holdback Agreements.

Holders of Registrable Securities. If requested by the managing underwriter(s), each Holder participating in an underwritten Public Offering shall enter into customary lock-up agreements, substantially consistent with the lock-up agreements entered into by such Holders in connection with the IPO, with the managing underwriter(s) of such Public Offering. Each Holder not participating in an offering pursuant to this Agreement agrees to be bound by the terms of such customary lock-up agreement entered into by the participating Holders in connection therewith as if such Holder had been a party thereto; provided that, notwithstanding the terms of the customary lock-up agreement entered into by the participating Holders, non-participating Holders shall not be prohibited from (i) establishing any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1) under the Exchange Act during the lock-up period set forth in such agreements (provided that no sales may be made pursuant to such a Plan prior to the expiration of the lock-up period set forth in such agreements and no public announcement of the establishment or existence of a Plan or filing in respect thereof is required or made voluntarily prior to the expiration of the lock-up period set forth in such agreements) or (ii) making sales pursuant to a Plan that exists on the date of the customary lock-up agreement entered into by the participating Holders. The Company may impose stop-transfer instructions with respect to the Shares (or other securities) subject to the restrictions set forth in this Section 4(a) until the end of the lock-up period set forth in such agreements, including any extension thereof as may be required to comply with FINRA Rule 2711(f)(4).

9

Exceptions. The foregoing holdback agreements in Section 4(a) shall not apply to a registration on Form S-8 or any successor or similar form or otherwise in connection with an employee benefit plan or in connection with any registration on Form S-4 or any successor or similar form in connection with any type of acquisition transaction or exchange offer.

In connection with each Demand Registration, each Piggyback Registration and each Shelf Offering that is an underwritten Public Offering, the Company shall reimburse the Holders of Registrable Securities included in such registration for the reasonable fees and disbursements of (i) one counsel chosen by the Holders representing a majority of the Registrable Securities included in such registration or participating in such Shelf Offering, and (ii) each additional counsel retained by any Holder for the purpose of rendering an opinion on behalf of such Holder in connection with any Demand Registration, Piggyback Registration or Shelf Offering that is an underwritten Public Offering, where the counsel referred to in clause (i) is unable or unwilling to render an opinion on behalf of such Holder.

Indemnification and Contribution.

By the Company. The Company shall indemnify and hold harmless, to the extent permitted by law, each Holder, such Holder’s officers, directors, managers, employees, agents and representatives, and each Person who controls such Holder (within the meaning of the Securities Act) (the “Holder Indemnified Parties”) against all losses, claims, actions, damages,

15

liabilities and expenses (including with respect to actions or proceedings, whether commenced or threatened, and including reasonable attorney fees and expenses) caused by, resulting from, arising out of, based upon or related to any of the following statements, omissions or violations (each a “Violation”) by the Company: (i) any untrue or alleged untrue statement of material fact contained in (A) any registration statement, prospectus, preliminary prospectus or Free Writing Prospectus, or any amendment thereof or supplement thereto or (B) any application or other document or communication (in this Section 7, collectively called an “application”) executed by or on behalf of the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify any securities covered by such registration under the securities laws thereof, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance. In addition, the Company will reimburse such Holder Indemnified Party for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such losses. Notwithstanding the foregoing, the Company shall not be liable in any such case to the extent that any such losses result from, arise out of, are based upon, or relate to an untrue statement or alleged untrue statement, or omission or alleged omission, made in such registration statement, any such prospectus, preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto, or in any application, in reliance upon, and in conformity with, written information prepared and furnished in writing to the Company by such Holder Indemnified Party expressly for use therein or by such Holder Indemnified Party’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such Holder Indemnified Party with a sufficient number of copies of the same. In connection with an underwritten offering, the Company shall indemnify such underwriters, their officers and directors, and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Holder Indemnified Parties.

By Each Holder. In connection with any registration statement in which a Holder is participating, each such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, shall indemnify the Company, its officers, directors, managers, employees, agents and representatives, and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder; provided that the obligation to indemnify shall be individual, not joint and several, for each Holder and shall be limited to the net amount of proceeds received by such Holder from the sale of Registrable Securities pursuant to such registration statement.

16

Claim Procedure. 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 (provided that the failure to give prompt notice shall impair any Person’s right to indemnification hereunder only to the extent such failure has prejudiced the indemnifying party) 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, 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 shall not be unreasonably withheld, conditioned or delayed). 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 for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. In such instance, the conflicted indemnified parties shall have a right to retain one separate counsel, chosen by the Holders representing a majority of the Registrable Securities included in the registration if such Holders are indemnified parties, at the expense of the indemnifying party.

Contribution. If the indemnification provided for in this Section 7 is held by a court of competent jurisdiction to be unavailable to, or is insufficient to hold harmless, an indemnified party or is otherwise unenforceable with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action 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 hand in connection with the statements or omissions which resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations; provided that the maximum amount of liability in respect of such contribution shall be limited, in the case of each seller of Registrable Securities, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Securities effected pursuant to such registration. The relative fault of the indemnifying party and of the indemnified party shall be determined 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. The parties hereto agree that it would not be just or equitable if the contribution pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account such equitable considerations. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to herein shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject hereof. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(t) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

17

Release. No indemnifying party shall, except with the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. Notwithstanding anything to the contrary in this Section 7, an indemnifying party shall not be liable for any amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the indemnifying party, such consent not to be unreasonably withheld, conditioned or delayed.

Non-exclusive Remedy; Survival. The indemnification and contribution provided for under this Agreement shall be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract and shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of Registrable Securities and the termination or expiration of this Agreement. Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the IPO are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

Underwritten Registrations.

Participation. No Person may participate in any Public Offering hereunder which is underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements (including, without limitation, pursuant to any over-allotment or “green shoe” option requested by the underwriters; provided that no Holder shall be required to sell more than the number of Registrable Securities such Holder has requested to include) and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements and that are consistent in all material respects with the documents to be completed and executed by the Holders. Each Holder shall execute and deliver such other agreements as may be reasonably requested by the Company and the lead managing underwriter(s) that are consistent with such Holder’s obligations under Section 4, Section 5 and this Section 8(a) or that are necessary to give further effect thereto and that are consistent in all material respects with the documents to be completed and executed by the Holders. To the extent that any such agreement is entered into pursuant to, and consistent with, Section 4 and this Section 8(a), the respective rights and obligations created under such agreement shall supersede the respective rights and obligations of the Holders, the Company and the underwriters created pursuant to this Section 8(a).

Price and Underwriting Discounts. In the case of an underwritten Demand Registration or Underwritten Takedown requested by a Holder pursuant to this Agreement, the price, underwriting discount and other financial terms of the related underwriting agreement for the Registrable Securities shall be determined by such Holder.

Suspended Distributions. Each Person that is participating in any registration under this Agreement, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 5(a)(vi)(B) or (C), shall immediately discontinue the disposition of its Registrable Securities pursuant to the registration statement until such Person’s receipt of the copies of a supplemented or amended prospectus as contemplated by Section 5(a)(vi).

18

Additional Parties; Joinder. Subject to the prior written consent of each Holder, the Company may make any Person who acquires Common Stock or rights to acquire Common Stock from the Company after the date hereof a party to this Agreement (each such Person, an “Additional Investor”) and to succeed to all of the rights and obligations of a Holder under this Agreement by obtaining an executed joinder to this Agreement from such Additional Investor in the form of Exhibit A attached hereto (a “Joinder”). Upon the execution and delivery of a Joinder by such Additional Investor, the Common Stock of the Company acquired by such Additional Investor or to which such Additional Investor has the right to acquire (the “Acquired Common”) shall be Registrable Securities to the extent provided herein, such Additional Investor shall be a Holder under this Agreement with respect to the Acquired Common, and the Company shall add such Additional Investor’s name and address to the Schedule of Investors and circulate such information to the parties to this Agreement.

Current Public Information. At all times after the Company has filed a registration statement with the Securities and Exchange Commission pursuant to the requirements of either the Securities Act or the Exchange Act, the Company shall file all reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as any Holder may reasonably request, all to the extent required to enable such Holders to sell Registrable Securities pursuant to Rule 144. Upon request, the Company shall deliver to any Holder a written statement as to whether it has complied with such requirements.

Subsidiary Public Offering. If, after an initial Public Offering of the Capital Stock of one of its Subsidiaries (including the Company), the Company distributes securities of such Subsidiary to its equityholders, then the rights and obligations of the Company pursuant to this Agreement shall apply, mutatis mutandis, to such Subsidiary, and the Company shall cause such Subsidiary to comply with such Subsidiary’s obligations under this Agreement.

MNPI Provisions.

Each Holder acknowledges that (i) the provisions of this Agreement that require communications by the Company or other Holders to such Holder may result in such Holder and its Representatives (as defined below) acquiring MNPI (which may include, solely by way of illustration, the fact that an offering of the Company’s securities is pending or the number of Company securities or the identity of the selling Holders), and (ii) there is no limitation on the duration of time that such Holder and its Representatives may be in possession of MNPI and no requirement that the Company or other Holders make any public disclosure to cause such information to cease to be MNPI; provided that the Company will use reasonable best efforts to promptly notify each Holder if any proposed registration or offering for which a notice has been delivered pursuant to this Agreement has been terminated or aborted.

19

Each Holder agrees that it will maintain the confidentiality of such MNPI and, to the extent such Holder is not a natural person, such confidential treatment shall be in accordance with procedures adopted by it in good faith to protect confidential information of third parties delivered to such Holder (“Policies”); provided that a Holder may deliver or disclose MNPI to (i) its directors, officers, employees, agents, attorneys, affiliates and financial and other advisors (collectively, the “Representatives”), but solely to the extent such disclosure reasonably relates to its evaluation of exercise of its rights under this Agreement and the sale of any Registrable Securities in connection with the subject of the notice, (ii) any federal or state regulatory authority having jurisdiction over such Holder, (iii) any Person if necessary to effect compliance with any law, rule, regulation or order applicable to such Holder, (iv) in response to any subpoena or other legal process, or (v) in connection with any litigation to which such Holder is a party; provided further, that in the case of clause (i), the recipients of such MNPI are subject to the Policies or agree to hold confidential the MNPI in a manner substantially consistent with the terms of this Section 12 and that in the case of clauses (ii) through (v), such disclosure is required by law and you promptly notify the Company of such disclosure to the extent such Holder is legally permitted to give such notice.

Each Holder, by its execution of a counterpart to this Agreement or of a Joinder, hereby (i) acknowledges that it is aware that the U.S. securities laws prohibit any Person who has MNPI about a company from purchasing or selling, directly or indirectly, securities of such company (including entering into hedge transactions involving such securities), or from communicating such information to any other Person under circumstances in which it is reasonably foreseeable that such Person is likely to purchase or sell such securities, and (ii) agrees that it will not use or permit any third party to use, and that it will use its reasonable best efforts to assure that none of its Representatives will use or permit any third party to use, any MNPI the Company provides in contravention of the U.S. securities laws and it will cease trading in the Company’s securities while in possession of MNPI.

Each Holder shall have the right, at any time and from time to time (including after receiving information regarding any potential Public Offering), to elect not to receive any notice that the Company or any other Holders otherwise are required to deliver pursuant to this Agreement by delivering to the Company a written statement signed by such Holder that it does not want to receive any notices hereunder (an “Opt-Out Request”); in which case and notwithstanding anything to the contrary in this Agreement the Company and other Holders shall not be required to, and shall not, deliver any notice or other information required to be provided to Holders hereunder to the extent that the Company or such other Holders reasonably expect would result in a Holder acquiring MNPI. An Opt-Out Request may state a date on which it expires or, if no such date is specified, shall remain in effect indefinitely. A Holder who previously has given the Company an Opt-Out Request may revoke such request at any time, and there shall be no limit on the ability of a Holder to issue and revoke subsequent Opt-Out Requests.

20

General Provisions.

Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company and each Holder; provided that no such amendment, modification or waiver that would adversely affect a Holder in a manner that is different from any other Holder (provided that the accession by any Additional Investor to this Agreement pursuant to Section 9 shall not be deemed to adversely affect any Holder), shall be effective against such Holder without the prior written consent of such Holder. The failure or delay of any Person to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such Person thereafter to enforce each and every provision of this Agreement in accordance with its terms. A waiver or consent to or of any breach or default by any Person in the performance by that Person of his, her or its obligations under this Agreement shall not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person under this Agreement.

Remedies. The parties to this Agreement shall be entitled to enforce their rights under this Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing hereunder, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement.

Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any jurisdiction, such prohibition, invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein.

Entire Agreement. Except as otherwise provided herein, this Agreement contains the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any way.

Successors and Assigns. This Agreement shall bind and inure to the benefit and be enforceable by the Company and its successors and assigns and the Holders and their respective successors and assigns (whether so expressed or not). In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit Holders are also for the benefit of, and enforceable by, any subsequent or successor Holder.

21

Notices. Any notice, demand or other communication to be given under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given or delivered (i) when delivered personally to the recipient, (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient but, if not, then on the next Business Day, (iii) one Business Day after it is sent to the recipient by reputable overnight courier service (charges prepaid) or (iv) three Business Days after it is mailed to the recipient by first class mail, return receipt requested. Such notices, demands and other communications shall be sent to the Company and the Holders at the addresses specified below and to any other party subject to this Agreement at such address or to the attention of such other Person as the recipient party has specified by prior written notice to the sending party.

23

No Recourse. Notwithstanding anything to the contrary in this Agreement, the Company and each Holder agrees and acknowledges that no recourse under this Agreement or any documents or instruments delivered in connection with this Agreement, shall be had against any current or future director, officer, employee, general or limited partner or member of any Holder or of any Affiliate or assignee thereof, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any current or future officer, agent or employee of any Holder or any current or future member of any Holder or any current or future director, officer, employee, partner or member of any Holder or of any Affiliate or assignee thereof, as such for any obligation of any Holder under this Agreement or any documents or instruments delivered in connection with this Agreement for any claim based on, in respect of or by reason of such obligations or their creation.

Descriptive Headings; Interpretation. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement. The use of the word “including” in this Agreement shall be by way of example rather than by limitation.

Counterparts. This Agreement may be executed in multiple counterparts, any one of which need not contain the signature of more than one party, but all such counterparts taken together shall constitute one and the same agreement.

RE:     Medpace Holdings, Inc. (the “Company”)

Ladies & Gentlemen:

The undersigned is an owner of shares of common stock, par value $0.01 per share, of the Company (“Shares”) or of securities convertible into or exchangeable or exercisable for Shares. The Company proposes to conduct a public offering of Shares (the “Offering”) for which Jefferies LLC (“Jefferies”) and Credit Suisse Securities (USA) LLC will act as the representatives of the underwriters. The undersigned recognizes that the Offering will benefit each of the Company and the undersigned. The undersigned acknowledges that the underwriters are relying on the representations and agreements of the undersigned contained in this letter agreement in conducting the Offering and, at a subsequent date, in entering into an underwriting agreement (the “Underwriting Agreement”) and other underwriting arrangements with the Company with respect to the Offering.

Annex A sets forth definitions for capitalized terms used in this letter agreement that are not defined in the body of this agreement. Those definitions are a part of this agreement.

In consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees that, during the Lock-up Period, the undersigned will not, and will use its reasonable best efforts to cause any Family Member not to, without the prior written consent of Jefferies, which may withhold its consent in its sole discretion:

granted by the Company pursuant to employee benefit plans or arrangements described in or filed as an exhibit to the registration statement with respect to the Offering, in each case on a “cashless” or “net exercise” basis, where any Shares received by the undersigned upon any such exercise or vesting will be subject to the terms of this lock-up agreement; provided that in the case of any transfer to the Company pursuant this clause, any filing under Section 16(a) of the Exchange Act shall state that such transfer to the Company relates to a “cashless” or “net exercise” of stock options or a tax withholding of shares in connection with the exercise of stock options or the vesting of a restricted stock award, as applicable, and that any Shares received by the undersigned upon any such exercise or vesting and not transferred to the Company will be continue to be subject to the terms of this lock-up agreement;

(viii) to transfers of Shares acquired in open market transactions after the completion of the Offering; and

(ix) in response to a bona fide third-party takeover bid made to all holders of Shares or any other, merger, consolidation, stock exchange or other similar transaction whereby all or substantially all of the Shares are acquired by a third party;

provided, however, that in the case of (A) any transfer or distribution pursuant to clauses (i) - (v) above, it shall be a condition to such transfer that both clauses (I) and (II) below are satisfied and (B) any transfer pursuant to clause (viii) above, it shall be a condition to such transfer that clause (II) below is satisfied:

(I) each transferee executes and delivers to Jefferies or already has in effect an agreement in form and substance satisfactory to Jefferies stating that such transferee is receiving and holding such Shares and/or Related Securities subject to the provisions of this letter agreement and agrees not to Sell or Offer to Sell such Shares and/or Related Securities, engage in any Swap or engage in any other activities restricted under this letter agreement except in accordance with this letter agreement (as if such transferee had been an original signatory hereto), and

(II) prior to the expiration of the Lock-up Period, no public disclosure or filing under the Exchange Act by any party to the transfer (donor, donee, transferor or transferee) shall be required, or made voluntarily, reporting a reduction in beneficial ownership of Shares in connection with such transfer.

The restrictions described in this letter agreement shall not apply to the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act during the Lock-Up Period, provided that no transfers occur under such plan during such Lock-up Period and no public announcement or filing shall be required or voluntarily made by any person in connection therewith during the Lock-Up Period.

If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any Company-directed Shares the undersigned may purchase or otherwise receive in the Offering (including pursuant to a directed share program).

In addition, if the undersigned is an officer or director of the Company, (i) Jefferies agrees that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Shares, Jefferies will notify the Company of the impending release or waiver, and (ii) the Company (in accordance with the provisions of the Underwriting Agreement) will announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by Jefferies hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if both (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter agreement that are applicable to the transferor to the extent and for the duration that such terms remain in effect at the time of the transfer.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of Shares or Related Securities held by the undersigned and the undersigned’s Family Members, if any, except in compliance with the foregoing restrictions.

With respect to the Offering only, the undersigned waives any registration rights relating to registration under the Securities Act of the offer and sale of any Shares and/or any Related Securities owned either of record or beneficially by the undersigned, including any rights to receive notice of the Offering.

The undersigned confirms that the undersigned has not, and has no knowledge that any Family Member has, directly or indirectly, taken any action designed to or that might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale of the Shares. The undersigned will not, and will use reasonable efforts to cause any Family Member not to take, directly or indirectly, any such action.

Whether or not the Offering occurs as currently contemplated or at all depends on market conditions and other factors. The Offering will only be made pursuant to the Underwriting Agreement, the terms of which are subject to negotiation between the Company and the underwriters.

The undersigned hereby represents and warrants that the undersigned has full power, capacity and authority to enter into this letter agreement. This letter agreement is irrevocable and will be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned.

If (i) the Company notifies Jefferies in writing that it does not intend to proceed with the Offering, (ii) the Underwriting Agreement is not executed before October 31, 2016 or (iii) the Underwriting Agreement (other than the provisions thereof that survive termination) terminates or is terminated prior to payment for and delivery of the Shares, then in each case, this letter agreement shall automatically, and without any action on the part of any other party, terminate and be of no further force and effect, and the undersigned shall automatically be released from the obligations under this letter agreement.

This letter agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
