	Re:	Employment Offer 

 Dear Henry: 

I am pleased to offer you employment at Bioventus LLC (“Bioventus” or the “Company”) on the terms set forth in this offer
letter agreement (the “Agreement”). This Agreement will be effective only on the closing date of the transaction in which certain assets and liabilities of Smith & Nephew plc (“Smith & Nephew”) will be
transferred to the Company (the “Effective Date”). This offer is contingent on your execution of a release agreement in favor of Smith & Nephew in the form attached as Exhibit C. 

Employment and Duties 
 You will be employed in the role
of Vice President – Strategic Planning & Business Development, and you shall perform the duties of this role as are customary and as may be required by Bioventus. You will report to the Chief Executive Officer, Mark Augusti and you will be
based at the headquarters of Bioventus currently located in Durham, NC. 
 During your employment with Bioventus, you will devote your full-time best
efforts and business time and attention to the business of Bioventus. 
 At-Will Employment Relationship 

You may terminate your employment with Bioventus at any time and for any reason whatsoever simply by notifying Bioventus. Likewise, Bioventus may terminate
your employment at any time, with or without Cause, and with or without advance notice. Your employment at-will status can only be modified in a written agreement approved by Bioventus and signed by you and a duly authorized member of Bioventus.

 Base Salary and Employee Benefits 
 Your base salary
will be paid at the initial annual rate of $309,001.00, less payroll deductions and withholdings. You will be paid your base salary on a bi-weekly basis, on Bioventus’ normal payroll schedule. As an exempt salaried employee, you will be
required to work Bioventus’ normal business hours, and such additional time as appropriate for your work assignments and positions. You will not be eligible for overtime premiums. 

You will be eligible to receive automotive, club and financial planning perquisites in the aggregate amount of $17,500.00 annually. 

You will be eligible to participate in Bioventus’ health and welfare, group insurance, retirement and other employee benefit plans, programs and
arrangements (pursuant to the terms and conditions of the benefit plans and applicable policies) as are made generally available from time to time to executives of the Company.

 You will also be eligible to receive an award of Phantom Profits Interest Units consistent with the terms of
the Bioventus Management Incentive Equity Plan. A copy of the plan will be made available for your review. 
 You will be eligible for 20 days of vacation
per year. For 2012, your vacation will be pro-rated for any days utilized prior to the Effective Date. Going forward, you will earn any additional vacation according to the Bioventus vacation policy. 

Bioventus may adjust your salary and benefits prospectively at any time at its sole discretion; however, Bioventus will not decrease your base salary or
Annual Bonus below the level set forth in this Agreement other than in the instance of an across-the-board salary or bonus reduction similarly affecting all senior executive officers of the Company. 

Annual Performance Bonus and Merit Planning 
 In this
position, you will be eligible to participate in the Bioventus Annual Incentive Plan at a target of forty (40%) percent of your annual base salary (“Annual Bonus”) which will be prorated for 2012 based on your length of employment with
Bioventus in 2012. The Annual Incentive Plan will include components of your personal performance as well as Bioventus’ Business Objectives. The terms and conditions of this plan will be set forth in the plan document. Your performance will be
reviewed on or before April 1, 2013 and on a yearly basis thereafter. At that time, your salary will be reviewed along with your performance to determine any adjustment to your base salary. 

Certain Definitions 
 For purposes of this Agreement, the
following definitions will apply: 
 (1) Definition of Change in Control. A “Change in Control” shall mean the first
to occur of any of the following: (A) any “person” (as such term is used in sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the “Exchange Act”)) (other than persons who are owners of the Company on the
Effective Date or its affiliates or permitted transferees) becomes a “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of interests in the Company representing more than 50% of the voting power
of the then outstanding interests in the Company; provided that a Change in Control shall not be deemed to occur as a result of a change of ownership resulting from the death of an owner, and a Change in Control shall not be deemed to occur as a
result of a transaction in which the Company becomes a subsidiary of another company and in which the owners of the Company, immediately prior to the transaction, will beneficially own, immediately after the transaction, interests entitling such
owners to more than 50% of all votes to which all owners of the parent company would be entitled in the election of members (without consideration of the rights of any class of membership interests to elect members by a separate class vote); or (B)
the consummation of (i) a merger or consolidation of the Company with another company where the owners of the Company, immediately prior to the merger or consolidation, will not beneficially own, immediately after the merger or consolidation,
membership interests (or other equity instruments) entitling such persons to more than 50% of all votes to which all owners of the surviving company would be entitled in the election of members (without consideration of the rights of any class of
membership interests to elect members by a separate class vote); (ii) a sale or other disposition of all or substantially all of the assets of the Company; or (iii) a liquidation or dissolution of the Company. 

(2) Definition of Cause. “Cause” for the Company to terminate your employment shall exist if any of the following
occurs: (A) your being convicted (including a guilty plea or plea of nolo contendere) of any felony or any other crime involving fraud, violence or dishonesty; (B) your commission of or

participation in a fraud or act of dishonesty or misrepresentation against the Company; (C) your material violation of any written and fully executed contract or agreement between you and the
Company, including without limitation, breach of your Proprietary Information, Inventions, Non-Competition and Non-Solicitation Agreement (the “Proprietary Information Agreement”); (D) your gross negligence or willful misconduct;
(E) your continued and substantial failure to perform your duties to the Company; or (F) your violation of any material policies, practices, or procedures of Bioventus. 

(3) Definition of Good Reason. “Good Reason” for you to terminate your employment shall mean the occurrence of any one
of the following events occurring during the two-year period following the date of a Change in Control without either (x) your express prior written consent or (y) full cure within 30 days after you give written notice to the Company: (i) material
diminution in duties or responsibilities; (ii) a material reduction in your salary, except for across-the-board salary reductions similarly affecting all senior executive officers of the Company; (iii) the relocation of your principal office, or
principal place of employment, to a location more than fifty (50) miles from the location of your principal office or principal place of business as of the Effective Date; or (iv) a failure to pay you earned compensation; provided however, that no
event shall constitute grounds for a Good Reason termination unless you terminate your employment within sixty days after such event occurs. 
 Severance
Benefits 
 If, at any time, (i) the Company terminates your employment without Cause, other than as a result of your death or disability or (ii) you
terminate your employment for Good Reason during the two-year period following a Change in Control, then you shall receive the following severance benefits (the “Severance Benefits”): (i) twelve (12) months of your base salary in
effect on the effective date of termination (the “Termination Date”), less applicable taxes and withholdings, paid in substantially equal installments on Bioventus’ regular payroll schedule beginning on the 60th day following the Termination Date and continuing for twelve (12) months; (ii) one hundred percent (100%) of your target Annual Bonus, paid on or about 60 days following the Termination Date (iii)
If you timely elect continued coverage under federal COBRA laws or comparable state insurance laws (“COBRA”), then the Company shall pay the COBRA premiums necessary to continue your medical and dental insurance coverage in effect
for yourself and your eligible dependents on the termination date for the first twelve (12) months of such coverage (provided that such COBRA reimbursement shall terminate on such earlier date as you are no longer eligible for COBRA coverage or you
become eligible for group health insurance benefits through a new employer). 
 Your receipt of the Severance Benefits is conditional upon (a) your
continuing to comply with your obligations under your Proprietary Information Agreement; and (b) your delivering to Bioventus within 45 days following the Termination Date (and not revoking) an effective, general release of all known and unknown
claims in favor of Bioventus in the form attached as Exhibit B. 
 Notwithstanding anything herein to the contrary, this Agreement is intended to be
interpreted and applied so that the payment of the benefits set forth herein shall either be exempt from the requirements of Section 409A of the Code (“Section 409A”) or shall comply with the requirements of such provision. After
the Termination Date, you shall have no duties or responsibilities that are inconsistent with having a “separation from service” (within the meaning of Section 409A) as of the Termination Date and, notwithstanding anything in the Agreement
to the contrary, distributions upon termination of employment of nonqualified deferred compensation may only be made upon a “separation from service” (as determined under Section 409A) and such date shall be the Termination Date for
purposes of this Agreement. Each payment under this Agreement or otherwise shall be treated as a separate payment for purposes of Section 409A. In no event may you, directly or indirectly, designate the calendar year of any payment to be made under
this Agreement which constitutes a “nonqualified deferral of compensation” (within the meaning of Section 409A) and to the

extent an amount is payable within a time period, the time during which such amount is paid shall be in the discretion of Bioventus. To the extent that any reimbursements are taxable to you, any
such reimbursement payment due to you shall be paid to you on or before the last day of the calendar year following the taxable year in which the related expense was incurred. The reimbursements are not subject to liquidation or exchange for another
benefit and the amount of such reimbursements that you receive in one taxable year shall not affect the amount of such reimbursements that you receive in any other taxable year. 

Compliance with Proprietary Information Agreement and Bioventus Policies 

As a condition of employment, you must sign and comply with Bioventus’ standard Proprietary Information Agreement which prohibits unauthorized use or
disclosure of Bioventus’ proprietary information and contains certain post-employment non-competition and non-solicitation obligations, among other obligations. In addition, you will be expected to abide by Bioventus’ Code of Conduct and
Bioventus’ policies, as may be changed from time to time at Bioventus’ sole discretion. 
 Non-Disparagement 

During and after your employment, you and Bioventus agree not to make any statement that criticizes, ridicules, disparages, or is otherwise derogatory of the
other or is reasonably likely to be harmful to you or Bioventus, or to your or Bioventus’ respective businesses, business reputations or personal reputations; provided, however, that nothing in this Agreement shall restrict either party from
making truthful statements (a) when required by law, subpoena, court order or the like; (b) when requested by a governmental, regulatory, or similar body or entity; (c) in confidence to a professional advisor for the purpose of securing professional
advice; (d) in the ordinary course of performing your or its duties during your employment; (e) from rebutting any statement made or written about you or it; or (f) from making normal competitive statements about Bioventus’ business or
products. 
 Outside Activities 
 Throughout your
employment with Bioventus, you may engage in civic, not-for-profit and personal financial investment activities so long as such activities do not interfere with the performance of your duties hereunder or violate this Agreement, the Bioventus
Conflict of Interest Policy or your Proprietary Information Agreement. 
 Assignment 

This Agreement may be assigned by Bioventus to a person or entity which is an affiliate or a successor in interest to substantially all of the business
operations of Bioventus. Upon such assignment, the rights and obligations of Bioventus hereunder shall become the rights and obligations of such affiliate or successor person. You may not assign your rights or obligations to another entity or
person. 
 Indemnification 
 You shall be entitled to
indemnification to the maximum extent permitted by applicable law and the Company’s Operating Agreement, Articles of Incorporation or Bylaws as applicable. At all times during your employment, the Company shall maintain in effect a directors
and officers liability insurance policy with you as a covered officer. The Company shall further provide and pay for the defense of any action, arbitration or mediation (collectively, an “Action”) relative to the lawful performance
of your duties or in connection with your employment at the Company and the existence of such Action or defense shall not provide grounds for termination of your employment.

 PROPRIETARY INFORMATION, INVENTIONS, 

NON-SOLICITATION, AND NON-COMPETITION AGREEMENT 

In consideration of my employment or continued employment by Bioventus LLC, its subsidiaries, parents, affiliates, successors and assigns (together, the
“Company”) and the compensation paid to me, I hereby enter into this Proprietary Information, Inventions, Non-Competition and Non-Solicitation Agreement (the “Agreement”) and agree as follows: 

1. NONDISCLOSURE. 
 1.1
Recognition of Company’s Rights. At all times during my employment and thereafter, I will hold in strictest confidence and will not disclose or use any of the Company’s Proprietary Information (defined below), except as such disclosure
or use may be required in connection with my work for the Company, or unless an officer of the Company expressly authorizes such in writing. I hereby assign to the Company any rights I may have or acquire in such Proprietary Information and
recognize that all Proprietary Information shall be the sole property of the Company. I will take all reasonable precautions to prevent the inadvertent or accidental disclosure of Proprietary Information. 

1.2 Proprietary Information. The term “Proprietary Information” shall mean any and all confidential and/or proprietary
knowledge, data or information of the Company, its affiliates, parents and subsidiaries, whether having existed, now existing, or to be developed during my employment. By way of illustration but not limitation, “Proprietary
Information” includes (a) trade secrets, inventions, ideas, processes, formulas, discoveries, developments, designs and techniques and any other proprietary technology and all Proprietary Rights therein (hereinafter collectively referred to
as “Inventions”); (b) information regarding research, development, new products, marketing and selling, business plans, budgets and financial statements, licenses, prices and costs, discounts, credit terms, pricing and billing
policies, quoting procedures, methods of obtaining or conducting business, forecasts, future plans and potential strategies, financial projections and business strategies, operational plans, financing and capital-raising plans, activities and
agreements, internal services and operational manuals, suppliers and supplier information, and purchasing; (c) information regarding customers and potential customers of the Company, including customer lists, names, representatives, their needs or
desires with respect to the types of products or services offered by the Company, proposals, bids, contracts and their contents and parties, the type and quantity of products and services provided or sought to be provided to customers and potential
customers of the Company and other related non-public information; (d) information regarding any of the Company’s business partners and their services, including names; representatives, proposals, bids, contracts and their contents and parties,
the type and quantity of products and services received by the Company, and other related non-public information; (e) information regarding personnel, employee lists, compensation, and employee skills; and (f) any other non-public information which
a competitor of the Company could use to the competitive disadvantage of the Company. Notwithstanding the foregoing, I am free to use information which is generally known in the trade or industry or information of which I was previously aware prior
to my employment with the Company and with Smith & Nephew plc (“Smith & Nephew”) through no breach of this Agreement or other act or omission by me and I am free to discuss the terms and conditions of my employment with others to
the extent permitted by law. 
 1.3 Third Party Information. I understand that the Company has received and in the future will
receive from third parties confidential and/or proprietary knowledge or information (“Third Party Information”). During my employment and thereafter, I will hold Third Party Information in the strictest confidence and will not
disclose to anyone (other than Company personnel who need to know such information in connection with their work for the Company) or use, except in connection with my work for the Company, Third Party Information unless expressly authorized by an
officer of the Company in writing.

 2. ASSIGNMENT OF INVENTIONS. 

2.1 Prior Inventions. Inventions, if any, patented or unpatented, which I made prior to the commencement of my employment with the
Company are excluded from the scope of this Agreement. To preclude any possible uncertainty, I have set forth on Exhibit A a complete list of all Inventions that I have, alone or jointly with others, conceived or developed prior to the
commencement of my employment with the Company, that I consider to be my property or the property of third parties, and that I wish to have excluded from the scope of this Agreement (collectively referred to as “Prior Inventions”).
If no such disclosure is attached, I represent that there are no Prior Inventions. I agree that I will not incorporate, or permit to be incorporated, Prior Inventions in any Company Inventions without the Company’s prior written consent. 

2.2 Assignment of Inventions. Subject to Subsection 2.3, I hereby assign and agree to assign in the future to the Company all my right,
title and interest in and to all Inventions (and all Proprietary Rights with respect thereto) made or conceived or learned by me, either alone or jointly with others, during the period of my employment with the Company. Inventions assigned to the
Company, or to a third party as directed by the Company pursuant to this Section 2, are hereinafter referred to as “Company Inventions.” The term “Proprietary Rights” shall mean all trade secrets, patents,
copyrights, trademarks and other intellectual property rights throughout the world. 
 2.3 Unassigned or Nonassignable Inventions.
This Agreement does not apply to an Invention which qualifies fully as a nonassignable Invention under North Carolina Statute §§ 66.57.1 and 66.57.2 (hereinafter “Statute 66.57.1-66.57.2”). I have reviewed the notification in
paragraph 3 of Exhibit A and agree that my signature acknowledges receipt of the notification. 
 3.
NON-SOLICITATION. During my employment and for a period of twelve (12) months following the termination of my employment with the Company for any reason, I shall not, directly or indirectly: 

3.1 solicit or attempt to solicit any Contractor (defined below) or strategic partner of the Company (i) as to which I was informed of
any confidential terms in the contract, business arrangement, or negotiation between the Company and such Contractor or strategic partner, or (ii) that is then providing, or is under contract to provide within one (1) year, services to the Company,
which would be interrupted or impeded as a result of such solicitation; 
 3.2 solicit or attempt to solicit, any Customer (defined
below) to terminate, diminish, or materially alter in a manner harmful to the Company its relationship with the Company for any purpose, including, but not limited to, the purpose of associating with or becoming a Customer of mine or any entity of
which I am or become a partner, stockholder, principal, member, officer, director, employee, agent, trustee or consultant; or 
 3.3
solicit or attempt to solicit, any Contractor to terminate, diminish, or materially alter in a manner harmful to the Company its relationship with the Company for any purpose, including, but not limited to, the purpose of associating with or
becoming a Contractor of mine or any entity of which I am or become a partner, stockholder, principal, member, officer, director, employee, agent, trustee or consultant.

I acquired Proprietary Information and that contracted for or received from the Company any product, service or process; or (ii) was in contact with me or in contact with any other employee, owner, or agent of the Company of which contact I was
aware, concerning any product, service or process with which I worked directly or indirectly during my employment with the Company or about which person or entity I acquired Proprietary Information as a result of my employment with the Company or
Smith & Nephew; or (iii) was solicited by the Company in an effort in which I was involved or aware or was in consideration or planning to be solicited by the Company in an effort in which I was involved concerning any product, service or
process of the Company. 
 3.5 For purposes of this Agreement, “Contractor” shall mean consultants or
independent contractors with whom the Company does business related to my work for the Company. 
 3.6 For purposes of this
Agreement, “Conflicting Services” means any product, service, or process of any person or organization other than the Company that directly competes with a product, service, or process or the like with which I worked directly
or indirectly during my employment by the Company or about which I acquired Proprietary Information during my employment by the Company. 
 4.
NON-INTERFERENCE. During the period of my employment with the Company and for twelve (12) months thereafter, I shall not, directly or indirectly, solicit or attempt to solicit, any person known to me to be an
employee of the Company to terminate his or her employment or other relationship with the Company for any purpose whatsoever. 
 5.
NON-COMPETE PROVISION. I agree that for the one (1) year period after the date my employment ends for any reason, I will not, directly or indirectly, as an officer, director, employee, consultant,
owner, partner, or in any other capacity solicit, perform, or provide, or attempt to perform or provide, Conflicting Services anywhere in any county in North Carolina, or in any other county in any other state in which the Company transacted its
business or the Company marketed its products or services during my employment with the Company and for which I have Proprietary Information that would be pertinent to such Conflicting Services, nor will I assist another person to solicit, perform
or provide or attempt to solicit, perform or provide Conflicting Services anywhere in such counties. 
 6. GENERAL
PROVISIONS. 
 6.1 Governing Law; Consent to Personal Jurisdiction. This Agreement will be governed by and
construed according to the laws of the State of North Carolina as such laws are applied to agreements entered into and to be performed entirely within North Carolina between North Carolina residents. I hereby expressly consent to the personal
jurisdiction and venue of the state and federal courts located in North Carolina for any lawsuit filed there against me by Company arising from or related to this Agreement. 

6.2 Severability. In case any one or more of the provisions, subsections, or sentences contained in this Agreement shall, for any
reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect the other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein. If moreover, any one or more of the provisions contained in this

Agreement shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing it, so as to be enforceable
to the extent compatible with the applicable law as it shall then appear. 
 6.3 Employment At-Will. I agree and understand that
nothing in this Agreement shall change my at-will employment status or confer any right with respect to continuation of employment by the Company, nor shall it interfere in any way with my right or the Company’s right to terminate my employment
at any time, with or without cause or advance notice. 
 6.4 Advice of Counsel. I ACKNOWLEDGE THAT, IN EXECUTING THIS AGREEMENT, I HAVE
HAD THE OPPORTUNITY TO SEEK THE ADVICE OF INDEPENDENT LEGAL COUNSEL, AND I HAVE READ AND UNDERSTOOD ALL OF THE TERMS AND PROVISIONS OF THIS AGREEMENT. THIS AGREEMENT SHALL NOT BE CONSTRUED AGAINST ANY PARTY BY REASON OF THE DRAFTING OR PREPARATION
HEREOF. 
 6.5 Entire Agreement. This Agreement is the final, complete and exclusive agreement of the parties with respect to the
subject matter hereof and supersedes and merges all prior discussions between us. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, will be effective unless in writing and signed by the party to be
charged. Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement. 

This Agreement shall be effective as of May 5, 2012 

I HAVE READ THIS AGREEMENT CAREFULLY AND
UNDERSTAND ITS TERMS. I HAVE COMPLETELY FILLED OUT EXHIBIT A TO THIS AGREEMENT.

NOW, THEREFORE, in consideration of the premises, 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 hereto hereby covenant and agree as follows: 
 1. Executive, for
himself, Executive’s spouse, heirs, administrators, children, representatives, executors, successors, assigns, and all other individuals and entities claiming through Executive, if any (collectively, the “Executive Releasers”),
does hereby release, waive, and forever discharge the Company and each of its respective agents, subsidiaries, parents, affiliates, related organizations, employees, officers, directors, attorneys, successors, and assigns in their capacities as such
(collectively, the “Employer Releasees”) from, and does fully waive any obligations of Employer Releasees to Executive Releasers for, any and all liability, actions, charges, causes of action, demands, damages, or claims for relief,
remuneration, sums of money, accounts or expenses (including attorneys’ fees and costs) of any kind whatsoever, whether known or unknown or contingent or absolute, which heretofore has been or which hereafter may be suffered or sustained,
directly or indirectly, by Executive Releasers in consequence of, arising out of, or in any way relating to: (a) Executive’s employment with the Company; (b) the termination of Executive’s employment with the Company; (c) the Agreement; or
(d) any events occurring on or prior to the date of this General Release. The foregoing release and discharge, waiver and covenant not to sue includes, but is not limited to, all waivable claims and any obligations or causes of action arising from
such claims, under common law including wrongful or retaliatory discharge, breach of contract (including but not limited to any claims under the Agreement other than claims for unpaid severance benefits, bonus or base salary earned thereunder) and
any action arising in tort including libel, slander, defamation or intentional infliction of emotional distress, and claims under any federal, state or local statute including the Age Discrimination in Employment Act (“ADEA”), Title
VII of the Civil Rights Act of 1964, the Civil Rights Act of 1866 and 1871 (42U.S.C. § 1981), the National Labor Relations Act, the Fair Labor Standards Act, the Employee Retirement Income Security Act, the Americans with Disabilities Act of
1990, the Rehabilitation Act of 1973, or the discrimination or employment laws of any state or municipality, and/or any claims under any express or implied contract which Executive Releasers may claim existed with Employer Releasees. This also
includes a release of

any claims for wrongful discharge and all claims for alleged physical or personal injury, emotional distress relating to or arising out of Executive’s employment with the Company or any of
its subsidiaries or affiliates or the termination of that employment; and any claims under the WARN Act or any similar law, which requires, among other things, that advance notice be given of certain work force reductions. Notwithstanding anything
contained in this Section 1 above to the contrary, nothing contained herein shall constitute a release by any Executive Releaser of any of his, her or its rights or remedies available to him, her or it, at law or in equity, related to, on account
of, in connection with or in any way pertaining to the enforcement of: (i) any rights to the receipt of employee benefits which vested on or prior to the date of this General Release; (ii) the right to receive severance and other benefits under the
Agreement; (iii) the right to continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act; (iv) any rights of Executive under the Agreement, the [Management Incentive Plan] or otherwise with respect to any phantom equity
rights; or (v) this General Release or any of its terms or conditions. 
 2. Excluded from this General Release and waiver are any claims which cannot be
waived by applicable law, including but not limited to the right to participate in an investigation conducted by certain government agencies. Executive does, however, waive Executive’s right to any monetary recovery should any government agency
(such as the Equal Employment Opportunity Commission) pursue any claims on Executive’s behalf. Executive represents and warrants that Executive has not filed any complaint, charge, or lawsuit against the Employer Releasees with any government
agency or any court. 
 3. Executive agrees never to seek personal recovery from any Employer Releasee in any forum for any claim covered by the above
waiver and release language, except that Executive may bring a claim under the ADEA to challenge this General Release. If Executive violates this General Release by suing an Employer Releasee (excluding any claim by Executive under the ADEA or as
otherwise set forth in Section 1 hereof), then Executive shall be liable to the party so sued for such party’s reasonable attorneys’ fees and other litigation costs incurred in defending against such a suit. Nothing in this General Release
is intended to reflect any party’s belief that Executive’s waiver of claims under ADEA is invalid or unenforceable, it being the intent of the parties that such claims are waived. 

4. Executive agrees that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any
time to be an admission by any party of any improper or unlawful conduct. 
 5. Executive acknowledges and recites that he has: 

(a) executed this General Release knowingly and voluntarily; 

(b) had a reasonable opportunity to consider this General Release; 

(c) read and understands this General Release in its entirety; 

(d) been advised and directed orally and in writing (and this subparagraph (d) constitutes such written direction) to seek legal counsel and
any other advice such party wishes with respect to the terms of this General Release before executing it; and 
 (e) relied solely on his
own judgment, belief and knowledge, and such advice as he may have received from his legal counsel.

any employee or agent of the Company, and Executive has had an opportunity to negotiate the terms of this General Release and (b) he has been offered twenty-one (21) calendar days after receipt of this General Release to consider its terms before

as applied to contracts made and to be performed entirely within North Carolina.

 EXHIBIT C 

Smith & Nephew, Inc. 

Bioventus LLC 
 April 20, 2012 

Re: Termination of Letter Agreement, dated November 16, 2009, between Smith & Nephew, Inc. and Henry Tung. 

Ladies and Gentlemen, 
 This letter agreement memorializes
certain agreements among Henry Tung (“Executive”), Smith & Nephew, Inc. (“S&N”) and Bioventus LLC (“Newco” and, together with Executive and S&N, the “Parties”)
with regard to the termination of the letter agreement, dated November 16, 2009, between Executive and S&N (the “Letter Agreement”) which provides for specified payments and benefits to be provided by S&N to Executive upon
an Involuntary Termination of his employment by S&N without Cause. Capitalized terms used but not defined in this letter agreement shall have the meanings given to them in the Letter Agreement. 

This letter agreement is contingent upon and will be effective only as of the occurrence of the following conditions (together, the
“Conditions”): (i) the execution of the Employment Offer agreement by and between Executive and Newco (the “Employment Offer Agreement”), (ii) the effectiveness of the Employment Offer Agreement as a binding
obligation of Newco and (iii) the closing of the transactions contemplated by the Contribution Agreement (the “Contribution Agreement”)-among S&N, Smith & Nephew plc, Beluga I, LLC, Beluga II, LLC,
Beluga III, LLC, Beluga IV, LLC, Beluga V, LLC, Beluga VI, LLC and Newco. Otherwise, this letter agreement is void and without any force or effect. 

Following the completion of the Conditions, the Letter Agreement shall terminate and shall cease to be of any force or effect. Furthermore, the Parties hereby
expressly agree and acknowledge that (i) the commencement of Executive’s employment with Newco shall not constitute an Involuntary Termination from S&N and (ii) the consummation of the transactions contemplated by the Contribution Agreement
shall not constitute a Change in Control under the Letter Agreement. 
 All questions concerning the construction, validity and interpretation of this
letter agreement shall be governed by the laws of the State of New York, without regard to the principles of conflict of laws. 
 All benefits of Executive
under the [Smith & Nephew 2001 US Share Plan, the 2004 Smith & Nephew Performance Share Plan, the Smith & Nephew Global Share Plan 2010, and the Smith & Nephew Deferred Bonus Plan] shall be paid in accordance with the rules, terms
and conditions of the applicable plan and the agreement evidencing such award. Executive will be considered a “good leaver” under plan rules.
