BONE PASTE SUPPLY

3.1 Exclusivity.

(a) Exclusive Distributor Appointment. Subject to MSDs right to subcontract or delegate in whole or in part to one or more third parties its obligations and responsibilities as distributor of Specialty Allografts as
expressly set forth in this Agreement, during the term of this Agreement, MSD shall be (i) the exclusive distributor for Specialty Allografts throughout the United States, Canada and Puerto Rico (the Exclusive Territory),
(ii) the non-exclusive distributor for Specialty Allografts in all other parts of the Territory, and (iii) the non-exclusive distributor for Bone Paste throughout the Territory; provided, however, with respect to Bone Paste, the grant of
rights herein shall be exclusive for the use of the trademark, service mark, trade name, design, graphics and logos associated with Osteofil. RTI agrees that any Bone Paste delivered other than pursuant to this Agreement shall contain a
different brand name and label than the Bone Paste delivered pursuant to this Agreement. MSD shall be entitled to distribute Bone Paste for use in all applications, including all musculoskeletal applications (orthopedic, trauma, etc.). RTI shall
not, and RTI shall ensure that any third party distributor does not, utilize or reference, directly or indirectly, in any manner the Osteofil name or any data with respect to the Osteofil product (including clinical and pre-clinical
data) in any marketing and promotional materials or in any materials filed with any applicable regulatory authority. RTI agrees that, during the period commencing with the Third Amendment Effective Date and ending on August 31, 2007, the only
companies that will have the right to distribute in the Exclusive Territory any product from the Osteofil family of Bone Paste are Exactech, Inc. and RTI (and, as set forth above, RTI and Exactech, Inc. shall not have the right to the
trademark, service mark, trade name, design, graphics and logos associated with Osteofil in connection with such distribution). During such period, RTI shall ensure that RTI and Exactech, Inc. distribute such Bone Paste only through
sales personnel that are employees of RTI or Exactech, Inc. as the case may be, or through the regional distributors identified in Schedule 3.1(a). RTI shall have the right from time to time to add to Schedule 3.1(a); provided that RTI obtains the
prior written consent of MSD, such consent not to be unreasonably withheld by MSD.

(b) RTI Covenant. Except
as otherwise provided for under this Agreement, RTI shall not, during the term of this Agreement, in any manner, directly or indirectly or by assisting others, (i) produce, manufacture, distribute, or assist with the marketing of Specialty
Allografts, (ii) engage in any manufacturing, distribution or marketing activities on behalf of any other individual or entity with respect to any Specialty Allografts or (iii) have an equity, profit or joint venture interest in, or render
services (of an executive, marketing, manufacturing, research and development, administrative, financial or consulting nature) to any business that produces, manufactures, distributes, or assists with the marketing of Specialty Allografts or
(iv) engage in any activities described in (i), (ii)



Page 8

or (iii) above with respect to any allograft tissue (other than Bone Paste) intended or expected to be primarily used in the spine.

(c) MSD Right to Compete. Notwithstanding any provision of this Agreement to the contrary, nothing in this Agreement shall
prohibit MSD from manufacturing, marketing or distributing allograft tissue or other products that compete, either directly or indirectly, with Specialty Allografts and Bone Paste. Schedule 3.1(c) attached hereto contains a list of all allograft
tissue or other products that MSD manufactures, markets or distributes that MSD believes may compete, either directly or indirectly, with Specialty Allografts. MSD shall update Schedule 3.1(c) within fifteen (15) days of the first day of each
calendar quarter starting July 1, 2004.

(d) Release of Exclusivity. MSD may release RTI from the
exclusivity provisions of this Agreement with respect to a specific Specialty Allograft by giving written notice thereof, upon which time MSDs rights hereunder with respect to such Specialty Allograft shall become nonexclusive but shall
otherwise remain in full force and effect. In addition, if the Binding Orders submitted by MSD for [###] for a specific Specialty Allograft are less than [###] of the average value of Binding Orders submitted by MSD to RTI for the same specific
Specialty Allograft for the immediately preceding [###], then RTI may notify MSD in writing of such shortfall. The Initial Stocking Order shall not be used in the calculation of the average value of Binding Orders submitted by MSD. Upon receipt of
such notice, MSD shall [###] in which to submit additional Binding Orders such that the total Binding Orders submitted by MSD for the [***] are not less than [###] of the average value of Binding Orders submitted by MSD for the same specific
Specialty Allograft for the immediately preceding [###]. If MSD fails to submit such additional Binding Orders, MSDs rights hereunder with respect to such Specialty Allograft shall become nonexclusive but shall otherwise remain in full force
and effect. Notwithstanding the foregoing, in the event that RTI delays or fails to deliver Specialty Allografts in sufficient quantity to meet a MSD Forecast or an MSD Binding Order, or regulatory actions delay delivery of the Specialty Allografts
then RTI shall not have the right to provide notice of a shortfall for any such period. With respect to a New Allograft, the average value of Binding Orders submitted by MSD and actually filled by RTI for the first full year of such New Allograft
shall be used for the purposes of this Section 3.1(d), provided, however, that MSD may submit an initial stocking order with respect to such New Allograft that will not be included in such calculation.

(e) International Distribution.MSDs agreement in Section 3.1(a) hereof to allow the distribution of Specialty Allografts or
other allograft tissue products in territories outside of the Exclusive Territory is specifically conditioned on the following conditions being met at all times:

RTI shall have the sole responsibility for payment to the appropriate taxing authorities of any taxes, tariffs, duties or excise, sales or use, value added or other taxes or levies imposed on the services provided by RTI under this Agreement.

3.4 Specialty Allograft and Bone Paste Supply; Forecasts. The Parties acknowledge and agree that donated human tissue is
necessary for the production of Specialty Allografts and Bone Paste, and that at times the demand for such products may exceed the supply due to limited amounts of donated human tissue. The Parties agree to use their mutual best efforts, including
MSDs knowledge of the needs of its customers and RTIs expertise in processing tissue, to match the available supply to the requirements of patients and healthcare providers for Specialty Allografts. Accordingly, the Parties agree to do

ARTICLE V

LICENSE AND SERVICE FEE

5.1 License and Service Fee. Beginning on the Implementation Date, MSD shall pay to RTI a license and service fee
(LSF) for Specialty Allografts and Bone Paste delivered to MSD from RTI pursuant to a Binding Order.

5.2 Initial
Fees.

(a) Bone Paste. The initial LSF for each unit of Bone Paste, by catalog number, shall be equal
to [###] of the average net distribution fee (ANDF) received by RTI for such catalog number between [###]. ANDF means the sum of the actual gross amounts invoiced to customers for such Bone Paste catalog number during such time
period (excluding items placed on consignment) less discounts, rebates paid or accrued, credits, taxes, shipping, handling and other fees, and less allowances and returns, and divided by the total number of units of each such Bone Paste catalog
number shipped during that period. The LSF for Bone Paste shall not exceed the [***]

(b) Specialty

of (i) the ANDF received by RTI for such Specialty Allograft catalog number between [###], or
(ii) the ANDF if listed on Schedule 2.1 for such Specialty Allograft catalog number, as the case may be. ANDF means the sum of the actual gross amounts invoiced to customers for such Specialty Allograft catalog number during such time period
(excluding items placed on consignment) less discounts, rebates paid or accrued, credits, taxes, shipping, handling and other fees, and less allowances and returns, and divided by the total number of units of each such Bone Paste catalog number
shipped. The initial LSF for Assembled Allografts shall be calculated in the same manner, except that the percentage shall be [###]; provided, however, if RTI receives all necessary government approvals to manufacture Assembled Allografts by
combining tissue from multiple donors in a single graft, the LSF for such Assembled Allografts shall be the same as the LSF for standard (non-assembled) Specialty Allografts of the same shape and dimensions. The LSF for nonexclusive Specialty
Allografts identified as on Schedule 2.1 shall not exceed the comparable LSF for such Specialty Allografts received by RTI from any other third party.

(c) Samples. The LSF for samples, not for implantation, of Specialty Allografts and Bone Paste ordered by MSD for samples, exhibits and training purposes shall be one half of the LSF for the Specialty
Allografts or Bone Paste, as the case may be, calculated in accordance with Section 5.2(a) or (b) above.

5.3 Adjustment to
License and Service Fee. Subject to the limitations contained in this paragraph, RTI may increase the LSF for any or all Specialty Allografts and Bone Paste on the first anniversary of the Implementation Date, and thereafter not more than
twice annually, upon [###] advance written notice to MSD. RTI may not increase the LSF for any Specialty Allograft such that the LSF for such Specialty Allograft or Bone Paste is greater than [###] of the ANDF (excluding items placed on consignment)
received by MSD for such Specialty Allograft over the preceding [###]. RTI may not increase the LSF for any Bone Paste such that the LSF for such Bone Paste is greater than [###]of the ANDF (excluding items placed on consignment) received by MSD for
such Bone Paste over the preceding [###]. In the event of a significant technological advance or a material increase in regulatory compliance costs that either Party reasonably anticipates will have an immediate and material impact on the
marketplace for Specialty Allografts or Bone Paste, the Parties will meet and confer in good faith on adjustments to the applicable LSFs, with the objective of adjusting each LSF to equal approximately [###] of the ANDF expected to be received by
MSD as a result of distribution of such Specialty Allografts, and [###] of the ANDF expected to be received by MSD as a result of distribution of such Bone Paste, as the case may be. Notwithstanding any other provision of this Agreement, the Parties
may mutually agree to alternative fee arrangements for any Specialty Allografts or Bone Paste.

5.4 Payment Terms. All LSF
payments shall be paid in U.S. Dollars within thirty (30) days of the later of MSDs receipt of Specialty Allografts or Bone Paste, as the case may be, pursuant to a Binding Order, or the receipt of RTIs invoice therefor. All LSF
fees shall be FOB MSDs place of business in Memphis, Tennessee, or such other locations within the 48 contiguous United States as the Parties may agree to designate.

(d) Sublicense of
Intellectual Property Rights. Upon the occurrence, and only during the continued existence, of a Supply Shortfall, MSD shall have the right to sublicense temporarily to Third Party Suppliers any Intellectual Property Rights of RTI reasonably
necessary to permit the Third Party Suppliers to process and manufacture Specialty Allografts and Bone Paste for distribution by MSD. Such sublicense and assistance shall apply only to those types and sizes of Specialty Allografts and Bone Paste
that RTI is unable to supply to MSD in quantities sufficient to meet a Binding Order or MSD Forecast and only for quantities needed to meet the Binding Order or MSD Forecast.

6.3 Development of New Allografts.

(a) New Allografts. The Parties acknowledge that while working under this Agreement, new allografts not listed on Schedule 2.1 and not covered by Section 2.3, may be developed by RTI or RTI and a third party
(RTI-Developed New Allografts) or the Parties jointly (Jointly-Developed New Allografts, collectively New Allografts). The Parties acknowledge that the provisions of this Section 6.3 are not
intended to cover Bone Paste.

(b) Development of Jointly-Developed New Allografts. If the Parties agree to develop a
Jointly-Developed Allograft, they will do the following:

(i) At MSDs request, RTI shall produce prototypes of any Jointly-Developed
New Allograft design for testing and clinical evaluation under the terms provided in this Section 6.3.

(ii) The Parties will dedicate
sufficient engineering and other resources to the ongoing development of any Jointly-Developed New Allograft so that such development will be timely and properly accomplished. The Parties will work to agree on specifications, development schedules

regulatory tests, studies and approvals with respect to a Jointly-Developed New Allograft; (ii) RTI shall be solely responsible for all costs related to
regulatory tests, studies and approvals with respect to its procurement, processing and manufacturing procedures and processes; and (iii) MSD shall reimburse RTI for its costs incurred in connection with the production of prototypes requested
by MSD, provided that such costs are mutually agreed to at the time of MSDs request for such prototypes.

(iv) The Jointly-Developed
New Allograft shall be added to Schedule 2.1 as a Specialty Allograft.

(c) LSF Applicable to Jointly-Developed
New Allografts. With respect to each Jointly-Developed New Allograft, the LSF shall be a percentage of the ANDF received by MSD for the first [###]of the distribution of the Jointly-Developed New Allograft, with such initial percentages
equaling [###] if the Jointly-Developed New Allograft is a Specialty Allograft (other than an Assembled Allograft) and [###] if the Jointly-Developed New Allograft is an Assembled Allograft, each calculated in accordance with Section 5.2.

(d) LSF Applicable to RTI-Developed New Allografts Primarily Useful For Spinal Fusion Surgery.

(i) Right of First Negotiation. In the event RTI develops an RTI-Developed New Allograft that is not a line extension as defined in
Section 2.3 hereof, yet will have applications primarily useful for spinal fusion surgery, RTI shall provide information to MSD with respect to the specifications of such product, along with prototypes and proof of viability (which shall
include, as appropriate, relevant in vitro, in vivo, and cadaveric test data). Within [###] after receipt of said information from RTI, MSD may determine it requires additional information to render a decision on its Right of First Negotiation on
the RTI-Developed New Allograft. If MSD reasonably requires additional information, MSD shall submit, in writing, to RTI a list of commercially and scientifically reasonable data it will require to render a decision on the RTI-Developed New
Allograft. MSD and RTI will meet in good faith to review and agree upon additional request for information. Within [###] of receipt of the agreed proof of viability, MSD and RTI shall meet and confer with respect to the feasibility of such product
and to confirm that such product is not a line extension as defined in Section 2.3 hereof. If the parties cannot agree as to what documentation is reasonably required to demonstrate viability, or as to whether such product is a line extension,
then the issue(s) shall be decided by a special master in accordance with Section 2.3. Otherwise, if the parties agree that such product is not a line extension or that sufficient additional information has been provided to MSD by RTI, MSD
shall give notice to RTI (within [###] of the end of the [###] period or within [###] of a special master determining that the product is not a line extension or that RTI has provided MSD with sufficient additional information to demonstrate
viability) as to whether MSD intends to exercise its

right of first negotiation for the RTI-Developed New Allograft as set forth in this
Section 6.3(d)(i). Any RTI-Developed New Allograft for which MSD elects to exercise its right of first negotiation shall be referred to herein as a Right of First Refusal Allograft. Any RTI-Developed New Allograft for which MSD
elects not to exercise its right of first negotiation shall be referred to herein as a Rejected Allograft. With respect to each Right of First Refusal Allograft, MSD shall have a right for a period of [###] after good faith
negotiations begin, to agree with RTI on the LSF for such Right of First Refusal Allograft. In the event RTI and MSD agree with respect to the LSF for such Right of First Refusal Allograft, then such Right of First Refusal Allograft shall be added
to Schedule 2.1 and shall become a Specialty Allograft for all purposes of this Agreement and the LSF for such Right of First Refusal Allograft shall be as agreed upon by RTI and MSD. With respect to each Rejected Allograft, RTI shall be
entitled to enter into an agreement with any third party for distribution of such Rejected Allograft provided such distribution does not violate any MSD Intellectual Property Rights.

(ii) Right of First Refusal. If after negotiating as set forth in Section 6.3(d)(i) as set forth above, MSD and RTI are unable to agree on the
LSF for a Right of First Refusal Allograft, then RTI shall have the right, for a period of an additional [###], to negotiate with independent third parties to establish the LSF for such Right of First Refusal Allograft. In the event RTI receives a
bona fide offer for the LSF of such Right of First Refusal Allograft (each an Offered LSF), then RTI shall provide written notice to MSD of the Offered LSF setting forth fully the terms of the Offered LSF (the LSF Offer
Notice) and MSD shall have [###] from the date of its actual receipt of the LSF Offer Notice to accept the LSF as set forth in the LSF Offer Notice, and upon such acceptance, the Right of First Refusal Allograft shall be added to
Schedule 2.1 and shall become a Specialty Allograft for all purposes of this Agreement and the LSF for such Right of First Refusal Allograft shall be as set forth in the LSF Offer Notice. In the event MSD does not accept the Offered LSF for
such Right of First Refusal Allograft prior to the expiration of its permitted [###] period, then RTI shall be entitled to enter into an agreement after the end of such [###] period with any third party for distribution of such Right of First
Refusal Allograft on terms as set forth in the LSF Offer Notice provided such distribution does not violate any MSD Intellectual Property Rights.

(e) RTI-Developed New Allografts Not Primarily Useful For Spinal Fusion Surgery. In the event RTI or RTI and a third party developer (if applicable) have a good faith belief that a particular RTI-Developed New Allograft will
not have applications primarily useful for spinal fusion surgery, then the provisions of Section 6.3(d) shall not apply to such RTI-Developed New Allograft, provided that the following provisions are followed:

(i) The development, marketing or distribution of any such RTI-Developed New Allograft will not violate any MSD Intellectual Property Rights;

---

(ii) Upon the market release of any such RTI-Developed New Allograft and at anytime after such market
release if new marketing or distribution support materials are developed, RTI will allow MSD complete access to review any marketing and distribution support materials for such product sufficient for MSD to make a determination as to whether or not
the product will have applications useful for spinal fusion surgery. In the event that the product is co-developed by RTI with any third party, RTI will use all commercially reasonable efforts to provide MSD with marketing and other materials as
soon as they are available. In the event any or all of the following are true, MSD can request that RTI immediately cease marketing of the product and/or collaboration with such third party on the product:

(A) The product is distributed (or intended to be distributed) by or for any party which also sells, markets or distributes products to be used primarily
in the spine; or

(B) The product is marketed (or intended to be marketed) to customers for use in spinal surgery; or

(C) MSD believes in good faith that such RTI-Developed New Allograft will have applications primarily useful for spinal fusion surgery.

(iii) In the event RTI refuses to cease such marketing or collaboration upon notice from MSD, then the matter will be submitted to the standing special
master. In the event the special master determines that either the product is distributed (or intended to be distributed) by or for any party which also sells, markets or distributes products to be used primarily in the spine or the product is
marketed (or intended to be marketed) to customers for use in spinal surgery, then RTI shall immediately case the marketing or distribution of the product. If the special master determines that neither of those events are occurring (or if they are
not at issue), then the special master will determine whether or not such product does or will have applications useful primarily for spinal fusion surgery.

(A) If the special master determines that such product does or will have applications primarily useful for spinal fusion surgery, then RTI will immediately cease marketing and/or collaboration with any third party on
the product and pay to MSD an amount equal to MSDs actual fees and expenses reasonably incurred in its review and prosecution of such issue and MSDs reasonably estimated lost revenues for products competitive with such spinal product as
determined by the special master.



Page 25



---

(B) If the special master determines that the product does not have applications primarily useful for
spinal fusion surgery, but is nevertheless being used frequently in the spine, then RTI may continue to market and collaborate with respect to such product, provided that RTI pays to MSD in the form of a rebate an amount equal to [###] of the
revenues derived by RTI or any RTI-related third party from distribution of such products that are used for spinal fusion surgery.

(C) If
the special master determines that the product does not have applications primarily useful for spinal fusion surgery, but is nonetheless used for such procedures on only rare occasions (defined as less than five percent (5%) of the distribution
of the product as determined by the special master), then MSD will pay RTI an amount equal to RTIs actual fees and expenses reasonably incurred in its review and defense of such issue.

(iv) MSD and RTI shall meet on a semi-annual basis to review the current status of any products developed and/or marketed under this Section 6.3(e)
and to discuss and attempt to address any concerns regarding this procedure;

(v) RTI provides reasonable assurances that MSD will still
receive priority on tissue suitable for Specialty Allografts distributed by MSD; and

(vi) RTI will agree not to enter into any third party
agreements that would prevent it from complying with this Agreement or that would prevent RTI from maintaining or having access to records that would hinder a determination of a products status under this Section 6.3.

(f) Initial New Allograft Forecast. With respect to any New Allograft added to Schedule 2.1 in accordance with the
terms of Section 6.3, MSD shall provide a good faith non-binding forecast of MSDs demand (each an Initial New Allograft Forecast) for such New Allograft for the following three (3) calendar months along with the
next scheduled MSD Forecast and such forecast may contain, in MSDs discretion, an initial stocking order. In subsequent months, such New Allografts shall be included in the MSD Binding Forecast and the MSD Forecasts.

6.4 Inspection Rights. RTI and MSD shall keep complete and accurate books and records which allow verification of the information contained
in fee schedules, invoices and shipping notices and other documentation required under this Agreement. Each Party shall be permitted access during normal business hours and upon reasonable notice during the term of this Agreement to such books and
records of the other Party that are necessary in order to verify the other Partys compliance with the terms of the Agreement.

6.5
Confidentiality. While this Agreement is in effect, and for two (2) years after the termination of this Agreement (or for such longer period as any such Confidential Information may constitute a trade secret), none of MSD or RTI,
their affiliates, or any directors,

shareholders, officers, employees or agents of the foregoing (collectively, the Affiliates) shall
divulge to anyone any Confidential Information (as hereinafter defined), except: (i) as required in the course of performing the obligations hereunder; (ii) to attorneys, accountants and other advisors; (iii) with the express written
consent of MSD or RTI (as the case may be); or (iv) as required by law. The term Confidential Information shall mean any information relating to MSD or RTI or their business which is, (1) disclosed to the other (or to the
others Affiliates) during the negotiation of and performance of this Agreement and (2) is marked Confidential if provided in writing, or if delivered verbally, is reduced to writing within thirty (30) days and marked
Confidential. Confidential Information shall also include the terms and conditions of this Agreement, all ordering and distribution information arising under this Agreement and all Intellectual Property Rights relating to
Specialty Allografts and Bone Paste. Confidential Information shall not include any information which (i) becomes public knowledge without breach by the other of this Agreement; (ii) is obtained by the other (or the
others Affiliates) from a person or business entity under circumstances permitting its disclosure to others; (iii) may be demonstrated to have been known at the time of receipt thereof as evidenced by tangible records; or (iv) is
required to be disclosed as a result of a judicial order or decree or governmental law or regulation. If a Party makes a disclosure of Confidential Information which is permitted by the terms of this Agreement, such Party shall give prior notice to
the other Party, cooperate with the other Party in efforts to prevent or restrict such disclosure and be responsible for ensuring that the person to whom it is disclosed maintains the confidentiality of such Confidential Information in accordance
with the terms of this Agreement.

6.6 Opinion of Counsel. On the Effective Date or as soon thereafter as is practicable, RTI
shall provide an opinion from Holland & Knight L.L.P., as counsel to RTI, dated as of the Effective Date, affirming (i) the legality of the commercial relationship described in this Agreement, (ii) the enforceability of this
Agreement, (ii) that the execution and delivery of this Agreement by RTI will not conflict with, or result in a breach or default under, RTIs charter, bylaws or other organizational documents or any agreement, contract, arrangement,
mortgage or indenture to which it is bound, and (iv) that this Agreement complies in all respects with all statutes, rules, regulations or orders applicable to RTI and Specialty Allografts and Bone Paste. MSD shall pay RTIs counsel actual
reasonable costs for updating counsels prior opinion letter RTIs counsel not to exceed $10,000.

6.7 Determination of
Inventorship and Ownership of Future Inventions. The Parties acknowledge that while working under this Agreement, they may develop inventions relating to Specialty Allografts having application in the spine (Subject
Inventions). The

Parties acknowledge that they may prepare patent applications directed to obtaining patent protection for Subject Inventions
(Subject Patent Applications). The Parties desire to properly determine inventorship and ownership rights between the Parties in any Subject Patent Application. Therefore, the Parties agree that going forward, they will follow the
process described in subsections (a) through (f) below to properly determine inventorship and ownership rights in any Subject Patent Application.

(a) IP Reviewer. The Parties shall jointly appoint a neutral, third party patent attorney to review Subject Patent Applications (an IP Reviewer). The IP Reviewer will be a registered
patent attorney and have at least fifteen years of experience in patent



Page 27



---

matters. If the Parties cannot mutually agree upon an IP Reviewer, one will be selected from a group of at least ten potential candidates identified by the
Center for Public Resources, Inc. or some other neutral, third-party organization to which the Parties agree. The IP Reviewer shall serve a term of one year after which the Parties may agree to renew the reviewers appointment or, if one Party
wishes a different reviewer be appointed, the Parties will jointly appoint a different IP Reviewer pursuant to the above process.

(b) Submissions to the IP Reviewer. The Parties will submit all Subject Patent Applications, including all related continuation, divisional and continuations-in-part patent applications, to the IP Reviewer for review within
thirty days after filing. Failure of a Party to submit a Subject Application to the reviewer shall be a material breach of this Agreement. The Parties will cooperate to properly assign inventorship and ownership of any Subject Patent Application if
a determination of inventorship or ownership is later made.

(c) Meet and Confer. The Party making the
submission of the Subject Patent Application shall, under an appropriate confidentiality agreement, simultaneously provide a copy of the same to a designated representative of the other Party not actively involved in the preparation of patent
applications for the Party. The designated representative may undertake an investigation for a period of up to thirty days from the date of the submission to evaluate potential ownership and inventorship issues. The Parties agree to meet and confer
no later than sixty days after the date of submission in a good faith effort to reach a mutual agreement concerning inventorship and ownership. The sixty day meet and confer period may be extended by mutual agreement of the Parties.

(d) IP Reviewer Determination. In the event the Parties are unsuccessful in reaching a mutual agreement, the IP Reviewer
shall be notified of the Parties failure to agree and shall determine whether a Subject Patent Application is an invention and property of RTI (RTI Invention), an invention and property of MSD (MSD
Invention), or an invention and property of both Parties (Joint Invention). The IP Reviewer shall endeavor to make a determination within ninety days of such notification. The Parties will cooperate to provide the IP
Reviewer with copies of the necessary documents (e.g., lab notebook pages, invention disclosure forms, test results, etc.), access to items (e.g., models, mock-ups, etc.), or access to people to allow the IP Reviewer to conduct his or her
investigation and make his or her determination. The IP Reviewer

shall notify the Parties in writing of his or her determination but the
reviewer will not provide written reasons for his or her determination. At a Parties request, the information considered by the IP Reviewer in making a given determination shall be made available to a Partys outside counsel for
counsels review, under an appropriate confidentiality agreement, so that the Party may decide if it wishes to challenge the reviewers determination in arbitration. The attorneys conducting any such review for a Party shall not be
actively involved in prosecuting patents for the Party.

(e) Procedure after Determination by IP Reviewer. If
the IP Reviewer determines that a Subject Patent Application is an RTI Invention, a MSD Invention, or a Joint



Page 28



---

Invention, and the Parties agree with the reviewers determination, the Parties will proceed accordingly with respect to the application, including, if
necessary, providing the necessary documents, signatures, assignments, or the like to allow the Parties or particular Party to prosecute and exploit the Subject Patent Application and any resulting patents. A Party may challenge the IP
Reviewers decision via arbitration as set forth in Section 9.12 provided, however, that (1) the arbitrator shall not be the IP Reviewer that made the determination with respect to the Subject Patent Application in question,
(2) the Parties will cooperate to expedite the resolution of the arbitration and the arbitration must be completed no later than six months after the arbitrator is appointed, (3) The IP Reviewers decision will not be disclosed to the
arbitrator, and (4) the arbitration hearing, if necessary, may be held in any location set by the arbitrator. Prior to the commencement of any such arbitration, the Parties will meet and confer in a good faith effort to resolve the dispute.

(f) Cooperation in prosecuting and exploiting Joint Invention. If it is determined that a Subject Patent
Application is a Joint Invention, the Parties will retain counsel to represent the parties jointly with respect to the Joint Invention and will cooperate in good faith to prosecute and exploit the Subject Patent Application and any resulting patents
including sharing costs and expenses incurred. To the extent new products, not listed on Schedule 2.1 or covered by Section 2.3, are developed that embody the Joint Invention and are intended or expected to be used primarily in the spine, such
products shall be added to Schedule 2.1 as a Specialty Allograft.

to this Agreement shall be brought in the courts of the State of Florida, County of Alachua or State of Tennessee, County of Shelby, or, if it has or can acquire jurisdiction, in the United States District Court for the Northern District of Florida
or the Western District of Tennessee, and each Party consents to the jurisdiction of such courts (and the appropriate appellate courts) in any such action or proceeding and waives any objection to venue laid therein. Notwithstanding the provisions
for arbitration in Section 9.12 hereof, RTI hereby agrees that any remedy at law for any breach of the provisions contained in Sections 3.1 or 6.3(d) hereof shall be inadequate and MSD shall be entitled to injunctive relief in addition to any
other remedy MSD might have at law or under this Agreement in order to enforce the provisions of such sections of this Agreement.

9.4

Party seeking to excuse performance, including, but not limited to, acts of God, fire, terrorism, explosion, weather, plague, war, insurrection, civil strife or riots, provided, however, such performance shall be excused only to the
extent of and during such disability and such Party takes reasonable efforts to remove the disability. Any Party seeking to excuse or delay performance under this Section 9.4 shall provide detailed written notice to the other Party of the
nature and anticipated duration of the delay.

9.5 Severability. In the event that any Part of this Agreement shall for any
reason be finally adjudged by a court of competent jurisdiction or determined by a governmental body to be invalid or unenforceable, then, unless such part is deemed material by either or both Parties,



Page 31



---

this Agreement shall continue in effect and such part shall be excised hereof. If either Party determines that such part hereof found to be invalid or
unenforceable is material to the operation or performance of this Agreement, then such Party may, by written notice to the other Party, request that the Parties attempt to renegotiate this Agreement to alleviate or eliminate any difficulty caused to
such Party by such invalidity or unenforceability.

9.6 Waiver. No failure or delay on the part of either Party to enforce
any provision of this Agreement or to exercise any right granted hereby shall operate as a waiver thereof unless or until the right to enforce any such provision or to exercise any such right has been waived in writing by such Party. Any waiver of
any provision hereof or right hereunder shall be effective only in accordance with its terms and may be restricted in any way. No waiver of any provision hereof or any right hereunder shall constitute a waiver of a continuance or reoccurrence of the
failure to perform, except as provided in such waiver.

9.7 No Third Party Beneficiaries. This Agreement shall be construed
to be for the benefit of the Parties hereto only and shall confer no right or benefit upon any other person.

9.8 Independent
Contractors. The Parties each acknowledge that they intend by this Agreement to establish the relationship of independent contractors with regard to the subject matter hereof and do not intend to undertake any relationship of principal and
agent or to create any joint venture or partnership or a fiduciary relationship between them or their respective successors in interest.
