3.           LICENSE
GRANT AND TECHNICAL ASSISTANCE


 


3.1         Licensed Technology.


 


(a)          Licensor hereby grants to
TranS1 an exclusive license (with the right to grant sublicenses through multiple tiers, subject to the terms hereof) under the
Licensed Technology and any of Licensor’s interests in Improvements for all uses, specifically including to conduct research
and to develop, make, have made, use, offer for sale, sell, import and otherwise exploit for commercial purposes Products in the
Territory for use in the Field. Such license grant is exclusive even as to Licensor, such that Licensor shall have no right to
make, have made, offer for sale, sell or import Products or any other products utilizing Licensed Technology. The license shall
remain in effect until this Agreement is terminated pursuant to Article 10. For clarification, the sale or other transfer of any
Product by or on behalf of TranS1 (or any authorized Affiliate or Sublicensee) to any purchaser, end user or other third party
shall authorize the purchaser or any subsequent end user to practice any rights related to the Licensed Technology and Improvements
(specifically including, without limitation, the right to conduct any procedure involving the use of Product, whether involving
plates, biologic material, a reusable retractor or any other component). However, nothing herein shall be deemed to restrict the
ability of Mitchell A. Hardenbrook to provide medical care to individual patients in accordance with his professional medical judgment,
to make, have made, and use Products (but not offer for sale or sell such Products) to personally provide medical care to his individual
patients until the Limited Market Release, or to purchase Products from TranS1 or any authorized Affiliate, Sublicensee or distributor
and to use such Products in accordance with his professional medical judgment.


 


(b)         The grants set forth in this
Section 3.1, shall apply to TranS1 and any Affiliate of TranS1. If any Affiliate of TranS1 exercises rights under this Agreement,
such Affiliate shall be bound by all terms and conditions of this Agreement to the same extent as would apply had this Agreement
been directly between Licensor and such Affiliate. In addition, TranS1 shall remain fully liable to Licensor for all acts and obligations
of such Affiliate, such that acts of said Affiliate shall be considered acts of TranS1.


 




    	5



    	 



    

 


(c)         TranS1 shall remain fully
liable to Licensor for all acts and obligations of Sublicensees, including payment of any royalties at the rates set forth herein,
such that acts of said Sublicensees shall be considered acts of TranS1. TranS1 shall provide Licensor with a true and correct copy
of any such sublicense which grants a third party the right to sell Product (subject to redaction of information, if any, not directly
related to Product or Licensed Technology), and any modification or termination thereof, within thirty (30) days following execution,
modification or termination. Notwithstanding the foregoing or anything else in this Agreement to the contrary, TranS1 shall have
the right to grant a sublicense to Licensed Technology to a Sublicensee on terms that do not require the payment of royalties on
the sale of Products by or on behalf of the Sublicensee (such a sublicense being referred to as a “Royalty Free Sublicense”).
If TranS1 grants a Royalty Free Sublicense, then sales of Product by such Sublicensee shall be disregarded in determining royalty
payment obligations hereunder but shall continue to be included in determining Sales-Based Milestone Payments. In lieu of paying
Licensor royalties in respect of Product sales made pursuant to a Royalty Free Sublicense, TranS1 shall pay Licensor an equitable
portion of the consideration paid to TranS1 pursuant to the Royalty Free Sublicense agreement. Prior to granting a Royalty Free
Sublicense, TranS1 shall notify Licensor of the proposed terms of such transaction and shall provide Licensor with such information
as Licensor may reasonably request in connection with the proposed transaction. The parties shall negotiate in good faith regarding
the terms and conditions of the Royalty Free Sublicense and the amount payable to Licensor in connection with such transaction.
If the parties are unable to agree on an equitable allocation of the consideration, the parties shall engage a mediator mutually
agreeable to the parties to assist the parties in reaching agreement. Any further dispute regarding such allocation shall be submitted
to arbitration in accordance with Section 13.3 of this Agreement. The failure to reach agreement in advance shall not limit TranS1’s
right to grant such a Royalty Free Sublicense.


 


(d)         In the event of termination
of this Agreement, any sublicense agreement with any Sublicensee shall provide for the termination of the sublicense or the conversion
to a license directly between such Sublicensee and Licensor on substantially the same terms as the sublicense agreement.


 


3.2         Transfer of Licensed Know-How;
Lateral Plate Development.


 


(a)         Within thirty (30) days
of the Effective Date and in so far as it has not previously done so, Licensor shall provide TranS1 with all Licensed Know-How,
including those items and materials identified on Exhibit B. Licensor shall use its commercially reasonable efforts to provide
such technical assistance to TranS1 as TranS1 reasonably requests related to the Licensed Technology or the design and commercialization
of the Products, not to exceed 10 hours per month, which assistance may include the training of sales personnel and engineers of
TranS1 and its affiliates. TranS1 shall reimburse Licensor for all reasonable out-of-pocket costs and expenses incurred by Licensor
in the course of providing such assistance. Licensor and TranS1 agree that any technical assistance provided by Licensor beyond
the scope contemplated in this Section 3.2, including without limitation training of physicians and significant tasks such as the
surgical techniques guide, shall be billed at an hourly rate to be mutually agreed upon by the parties prior to the performance
of such services.


 


(b)         Licensor shall provide
such technical assistance as may be reasonably requested by TranS1 with respect to the development of a lateral plate Product.
TranS1 shall reimburse Licensor for all reasonable out-of-pocket costs and expenses incurred by Licensor in the course of providing
such assistance, but in lieu of any hourly billing rate, Licensor shall be eligible to receive a royalty based on sales of a resulting
lateral plate Product.

3.3         Bankruptcy. All rights
and licenses granted under or pursuant to any section of this Agreement are, and shall otherwise be deemed to be, for purposes
of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101(35A)
of the Bankruptcy Code. The parties shall retain and may fully exercise all of their respective rights and elections under the
Bankruptcy Code. Upon the bankruptcy of any party, the non-bankrupt party shall further be entitled to a complete duplicate of
(or complete access to, as appropriate) any such intellectual property, and such, if not already in its possession, shall be promptly
delivered to the non-bankrupt party, unless the bankrupt party elects to continue, and continues, to perform all of its obligations
under this Agreement.


 


4.           FINANCIAL
CONSIDERATIONS


 


4.1         License Fees. On or before
January 31, 2011, TranS1 shall pay to Licensor a non-refundable, non-creditable license fee in the amount of US$[***], which amount
reflects a license fee of $[***] less a credit for $[***] for a payment made to Licensor pursuant to that certain letter of intent
dated September 27, 2010 (the “LOI”).


 


4.2         Development-Based Milestone
Payments. At such time as TranS1 (or its Affiliates or Sublicensees) achieves a milestone event as described below, TranS1
shall pay to Licensor the Milestone Payment specified below. For avoidance of doubt, only one of each such development-based milestone
payments shall be payable, notwithstanding that there may be multiple Products and/or replacement Products. TranS1 shall notify
Licensor within five (5) business days after any of the milestone events described below has actually been achieved, and, except
as provided for in Section 10.2, the specified milestone payment shall be made within ten (10) days after such notification.

	(1)	 Completion of Limited Market Release	 	$	[***]
	 	 	 	 	 
	(2)	Full Commercial Launch	 	$	[***]
	 	 	 	 	 
	(3)	Issuance in the U.S. of a patent included in the Licensed Patent Rights with one or more Valid Claims Covering the use of Product in the lateral spine procedure described in the Licensed Know-How (the “IP Milestone”)	 	$

4.3         Sales-Based Milestone Payments.
At such time as the Net Sales of Products by TranS1 and its Affiliates and Sublicensees, collectively, first reach the Net Sales
amount set forth below, TranS1 will pay to Licensor the following milestone payments:


 


	Net Sales	 	Milestone Payment
	 	 	 	 
	US $[***] in any calendar year	 	US $	[***]
	 	 	 	 
	US $[***] in any calendar year	 	US $	[***]
	 	 	 	 
	US $[***] in any calendar year	 	US $	[***]
	 	 	 	 
	US $[***] in cumulative total Net Sales after the Effective Date	 	US $	[***]


 


For avoidance of doubt, only one of each such Sales-based milestone
payments shall be payable, notwithstanding that there may be multiple Products and/or replacement Products, but the Sales of all
Products and replacement Products shall be aggregated to determine achievement of such Sales-based milestones.


 


Said payment shall be made within ninety (90) days after the
end of the calendar year in which the annual Net Sales milestone was achieved and within ninety (90) days after the end of the
calendar month in which the cumulative Net Sales milestone was achieved.


 


4.4         Royalties.


 


4.4.1      Royalty Rate. TranS1
shall pay to Licensor, in the manner set forth in Section 5.1, royalties on Net Sales of each Product sold by TranS1 and its Affiliates
or Sublicensees at a royalty rate as follows:


 


(a)         For all sales of Product during
the period from the date of the start of the Limited Market Release through the last day of the month of the third anniversary
of the start of the Limited Market Release (the “Initial Launch Period”): [***]% of Net Sales.


 


(b)         For all sales of Product after
achievement of the IP Milestone: [***]% of Net Sales.


 


(c)         For all sales of Product after
the Initial Launch Period and prior to achievement of the IP Milestone: [***]% of Net Sales.


 


[***] Confidential treatment requested pursuant to a request

the Commission.


 




    	8



    	 



    

 


(d)         If the IP Milestone has not
been achieved prior to the expiration of the Initial Launch Period, TranS1 shall be granted a credit against future royalty payments
in an amount equal to [***] percent ([***]%) of all royalty payments made by TranS1 with respect to Net Sales during the Initial
Launch Period (such that the effective royalty rate on sales of Product during the Initial Launch Period will be retroactively
reduced to [***]%). However, if the IP Milestone is achieved after the Initial Launch Period, the royalty rate shall be increased
from [***]% to [***]% of Net Sales on a retroactive basis for all Net Sales of Product prior to the achievement of the IP Milestone
and before the end of the Royalty Term (including Net Sales during and after the Initial Launch Period). TranS1 shall pay the retroactive
royalty on past Net Sales within thirty (30) days of the achievement of the IP Milestone. If the IP Milestone is achieved and thereafter
the relevant Valid Claim or Valid Claims Covering the use of Product in the lateral spine procedure described in the Licensed Know-How
is subject to challenge, reexamination or other legal process which results in the use of Product in the lateral spine procedure
described in the Licensed Know-How being Covered by no Valid Claims in the United States (e.g., as a result of any applicable Valid
Claim being found to be invalid or unenforceable, but specifically excluding the expiration in the U.S. of the relevant patent),
then TranS1 shall be granted a credit against future royalty payments in an amount equal to [***] percent ([***]%) of all royalty
payments made by TranS1 at the rate of [***]% of Net Sales (such that the effective royalty rate on all sales of Product will be
retroactively reduced to [***]%).


 


(e)         For all sales of Product after
completion of the Royalty Term: [***]% of Net Sales.


 


(f)         Notwithstanding any reference to a [***]% royalty
rate set forth above, the royalty rate for any Product that comprises an implantable lateral plate shall be: (1) [***]% of Net
Sales if the Product is Covered by one or more Valid Claims; and (2) [***]% if the Product is not Covered by one or more Valid
Claims. If a procedure involves the sale of a lateral plate Product and another Product (e.g., an implantable cage), the royalty
under this paragraph (f) shall apply with respect to the lateral plate Product and the applicable royalty under paragraph (a)-(e)
shall apply with respect to the other Product.


 


Only one royalty shall be payable hereunder for a Product regardless
of how many Valid Claims Cover such Product. In no event shall TranS1 have any obligation to pay royalties or any other payments
in respect of the sale of any biologic material or other biologically or chemically active agent incorporated into or delivered
with the use of any Product. The parties agree that TranS1’s willingness to pay royalties upon the sale of an implantable
lateral plate Product is conditioned upon Licensor’s performance of the obligations set forth in Section 3.2(b). Accordingly,
if TranS1 develops an implantable lateral plate Product and Licensor does not meet its obligations under Section 3.2(b), then TranS1
shall have the right to pay no royalty with respect to the sale of any implantable lateral plates. Moreover, no royalty shall be
payable to Licensor with respect to any Product sold to Mitchell A Hardenbrook or to any business or medical practice in which
Dr. Hardenbrook owns, directly or indirectly, any profits or ownership interest (other than any publicly-held or traded company
in which Dr. Hardenbrook owns less than a two percent (2%) ownership interest) and any sales to such persons shall be excluded
in calculating sales-based milestone payments.


 


[***] Confidential treatment requested pursuant to a request
for confidential treatment filed with the Securities and Exchange Commission. Omitted portions have been filed separately with
the Commission.

Neither Licensee, its Affiliates nor its
Sublicensees may (a) use any Products as end users without paying a royalty based on the fair market value of such Product, except
to demonstrate the Products to potential customers, or (b) sell, lease, license or otherwise dispose of any Products for use other
than in the Field. Licensee, its Affiliates and Sublicensees may use or dispose of reasonable quantities of Products at discounted
prices or for no consideration for bona fide promotional purposes intended to promote sales of Products.


 


4.4.2      Minimum Royalties.


 


(a)         TranS1 shall pay to Licensor

royalties paid by TranS1 on Net Sales of Product with respect to Net Sales during a Contract Year are not equal to or more than
the Minimum Royalty set forth above for such Contract Year, TranS1 shall pay the difference between the actual royalties paid to
Licensor based on Net Sales during such year and the applicable Minimum Royalty in order to satisfy its minimum royalty obligations.

(c)         If for any period of three consecutive
Contract Years during the Royalty Term, the actual royalties paid by TranS1 on Net Sales of Product during each Contract Year (not
including any Minimum Royalty payment made by TranS1 pursuant to Section 4.4.2(b)) are not equal to or more than the Minimum Royalty
requirement set forth above for such Contract Year (other than due to a Force Majeure Event), Licensor may elect to modify the
license granted in Section 3.1 from exclusive to non-exclusive by providing TranS1 written notice no later than ninety (90) days
following the end of the third (3rd) year of such period. If Licensor elects to convert the license to a non-exclusive
license, TranS1’s obligation to make any Minimum Royalty payments for subsequent Contract Years shall terminate; provided,
however, that all other payments required to be made by TranS1 in this Agreement shall continue to apply, and TranS1 shall continue
to make commercially reasonable efforts to commercialize one or more Products. Licensor acknowledges and agrees that provided TranS1
is not in material breach of any other material obligations set forth in this Agreement, such right to modify this license to a
non-exclusive license shall be Licensor’s sole and exclusive remedy in the event TranS1 shall fail to achieve Net Sales of
Product sufficient to meet the Minimum Royalty obligations set forth herein. No minimum royalties shall be due for any period after
the termination of this Agreement.


 


5.           ROYALTY
REPORTS


 


5.1         Royalty Reports. Within ninety
(90) days after the end of each calendar quarter during the term of this Agreement following the Limited Market Release, TranS1
shall furnish to Licensor a quarterly written report showing (a) the calculation of Net Sales during such calendar quarter;
(b)  the calculation of Net Sales to date during such calendar year; (c) until payment of the milestones provided for
in Section 4.3, the calculation of cumulative total Net Sales after the Effective Date; (d) the calculation of the amounts payable,
if any, that shall have accrued based upon such Net Sales, including royalties and any Sales-based milestone payments; (e) the
withholding taxes, if any, required by law to be deducted with respect to such payments; and (f) the exchange rates, if any,
used in determining the amount of United States dollars. With respect to sales of Products invoiced in United States dollars, the
gross sales, Net Sales and royalties payable shall be expressed in United States dollars. With respect to (i) Net Sales invoiced
in a currency other than United States dollars and (ii) cash consideration paid in a currency other than United States dollars,
all such amounts shall be expressed both in the currency in which the distribution is invoiced and in the United States dollar
equivalent. The United States dollar equivalent shall be calculated using the average exchange rate during such quarter as published
in The Wall Street Journal, Eastern Edition, under the heading “Currency Trading” The daily average shall be
determined by adding together the closing exchange rate for each business day in New York, New York during such quarter and dividing
such amount by the number of business days during such quarter.


 


5.2         Audit Rights. During
the term of this Agreement, and for a period of three (3) years following the termination hereof, TranS1 shall keep full, true
and accurate records and accounts, in accordance with generally accepted accounting principles, to support TranS1’s calculation
of Net Sales and the amounts payable, if any, that shall have accrued based upon such Net Sales, including royalties and any Sales-based
milestone payments. Licensor shall have the right, on prior written notice to TranS1, to examine the audit work papers prepared
by Licensor’s outside auditors related to Product or to have such work papers examined by an independent auditor, during
normal business hours, to determine TranS1's compliance with this Agreement, in each case at Licensor’s expense. If, as a
result of such review, it is determined that TranS1 has underpaid Licensor, TranS1 will pay the amount due, plus interest at the
rate specified in Section 6.1 calculated from the due date for the applicable payment within thirty (30) days following the date
that the discrepancy is determined. If the amount of underpayment for any Contract Year exceeds $[***], TranS1 shall also reimburse
the reasonable expenses incurred by Licensor in connection with the examination. Records for any Contract Year are subject to review
within three years of the end of such Contract Year and no Contract Year may be reviewed more than one time.

shall accrue on any overdue payments at the rate of the lesser of (a) [***]% per month or (b) [***].


 


6.2         Withholding Taxes.          TranS1
will make all payments to Licensor under this Agreement without deduction or withholding for taxes except to the extent that any

under this Agreement will promptly be paid by TranS1 on behalf of Licensor to the appropriate governmental authority, and TranS1
will furnish Licensor with proof of payment of such tax. Any such tax required to be withheld will be an expense of and borne by
Licensor. TranS1 and Licensor will cooperate with respect to all documentation required by any taxing authority or reasonably requested
by TranS1 or Licensor to secure a reduction in the rate of applicable withholding taxes, a claim for income tax credit or refund
in respect of any sum so withheld, as applicable.

7.1         Development. TranS1 (directly
or through one or more Affiliates or Sublicensees) will be responsible for all product development and regulatory matters related
to the Product in the Territory and will bear the associated costs. TranS1 will use commercially reasonable efforts to obtain and
maintain one or more Registrations to market and sell Products, but nothing in this Agreement shall be construed as a guaranty
that any Registration required to market and sell Product will be successfully obtained or maintained in any country in the Territory.

use commercially reasonable efforts to achieve Full Commercial Launch of the initial Product by the first quarter of 2012 or as
soon thereafter as reasonably practicable. During the Royalty Period, TranS1 shall continue active, diligent marketing efforts.

8.           CONFIDENTIALITY


 


8.1         Confidential Information.
During the term of this Agreement, and for a period of three (3) years following the termination hereof, each party shall maintain
in confidence all information of the other party that is disclosed by the other party and identified as, or acknowledged to be,
confidential at the time of disclosure (the “Confidential Information”), and shall not use, disclose or grant the use
of the Confidential Information except on a need-to-know basis to those directors, officers, affiliates, employees, permitted licensees,
sublicensees, permitted assignees and agents, consultants, clinical investigators or contractors, to the extent such disclosure
is reasonably necessary in connection with performing its obligations or exercising its rights under this Agreement. To the extent
that disclosure is authorized by this Agreement, prior to disclosure, each party hereto shall obtain agreement of any such Person
to hold in confidence and not make use of the Confidential Information for any purpose other than those permitted by this Agreement.
Each party shall notify the other promptly upon discovery of any unauthorized use or disclosure of the other party’s Confidential
Information.


 


8.2         Permitted Disclosures.
The confidentiality obligations contained in Section 8.1 above shall not apply to the extent that (a) any receiving party
(the “Recipient”) is required (i) to disclose information by law, regulation or order of a governmental agency or a
court of competent jurisdiction, or (ii) to disclose information to any governmental agency for purposes of obtaining approval
to test or market a Product, or (b) the Recipient can demonstrate that (i) the disclosed information was public knowledge
at the time of such disclosure to the Recipient, or thereafter became public knowledge, other than as a result of actions of the
Recipient in violation hereof; (ii) the disclosed information was rightfully known by the Recipient (as shown by its written
records) prior to the date of disclosure to the Recipient by the other party hereunder; (iii) the disclosed information was
disclosed to the Recipient on an unrestricted basis from a source unrelated to any party to this Agreement and not under a duty
of confidentiality to the other party; or (iv) the disclosed information was independently developed by the Recipient without use
of the Confidential Information disclosed by the other party. Notwithstanding any provision of this Agreement, Recipient may disclose
Confidential Information disclosed by the other party relating to Product to any Person with whom Recipient has, or is proposing
to enter into, a business relationship, as long as such Person has entered into a confidentiality agreement with Recipient. In
addition, TranS1 may use and disclose all Licensed Technology as necessary or appropriate to research, develop and commercialize
Products or otherwise to exercise its rights and meet its obligations hereunder.

8.3         Terms of this Agreement.
On or after the Effective Date, the Parties may issue one or more press releases, the timing and content of which shall be mutually
agreed. The Parties agree that any such announcement shall not contain confidential business or technical information and, if disclosure
of confidential business or technical information is required by Law or regulation (including any applicable stock exchange or
Nasdaq listing requirements), shall make commercially reasonable efforts to minimize such disclosure and obtain confidential treatment
for any such information which is disclosed to a governmental agency or group. Each Party agrees to provide to the other Party
a copy of any public announcement relating to this Agreement or the subject matter of this Agreement as soon as reasonably practicable
under the circumstances prior to its scheduled release. Except under extraordinary circumstances, each Party shall provide the
other with an advance copy of any press release at least three business days prior to the scheduled disclosure. The contents of
any approved announcement or similar publicity which has been reviewed and approved by the reviewing Party can be re-released by
either Party without a requirement for re-approval. Notwithstanding anything herein to the contrary, TranS1 shall have the right
to make any disclosures or filings required to comply with applicable law, including regulations promulgated by the United States
Securities and Exchange Commission.


 


9.           PATENTS


 


9.1         Patent Prosecution and Maintenance.
Within thirty days after the Effective Date, Licensor shall provide TranS1 with all material information on all pending prosecution
matters regarding the Licensed Patent Rights, including without limitation, all filings and correspondence with the relevant patent
office. TranS1 shall have primary control of all patent prosecution of the Licensed Patent Rights at TranS1’s costs and expense
with counsel of its own choosing, reasonably acceptable to Licensor. TranS1 will direct its patent counsel to copy Licensor on
material communications regarding the Licensed Patent Rights. TranS1 shall confer with Licensor on any response to any patent action
and shall give Licensor’s comments due consideration; provided, however, that the final decision on all responses and actions
regarding prosecution of the Licensed Patent Rights shall be with TranS1. TranS1 will use commercially reasonable efforts to complete
patent prosecution of the Licensed Patent Rights as quickly as reasonably possible. If TranS1 does not or does not wish to continue
to maintain any patent applications or patents within the Licensed Patent Rights, Licensor may assume control of such patent applications
or patents on a country-by-country basis (the “Assumed Patent Rights”) at its sole cost and expense. In such event,
the Assumed Patent Rights shall thereafter continue to be licensed to TranS1 on an exclusive basis. TranS1 may elect, at any time
on a patent-by-patent and country-by-country basis, to surrender its license to any Patent Rights included within the Licensed
Patent Rights.


 


9.2         Notification of Infringement.
Each party shall notify the other party of any substantial infringement known to such party of any Licensed Patent Rights within
ten days of discovery thereof and shall provide the other party with the available evidence, if any, of such infringement within
ten days of request.


 




    	14



    	 



    

 


9.3         Enforcement of Licensed Technology.
TranS1 shall have the right to determine the appropriate course of action to enforce the Licensed Technology in the Territory or
otherwise abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce Licensed Technology in
the Territory, to defend any declaratory judgments seeking to invalidate or hold the Licensed Patent Rights in the Territory unenforceable,
to control any interference, reexamination, litigation or other enforcement action and to enter into, or permit, the settlement
of any such litigation, declaratory judgments or other enforcement action with respect to Licensed Technology, in each case in
TranS1’s own name and, if necessary for standing purposes, in the name of Licensor. No settlement, consent judgment, or other
voluntary final disposition of any such suit that would have a material adverse effect on the validity, scope or enforceability
of the Licensed Patents Rights, by estoppel, admission or otherwise, may be entered into without the consent of a Licensor, which
shall not be unreasonably withheld. In any suit to enforce and/or defend the Licensed Technology, Licensor shall be permitted to
participate at its own cost and expense through attorneys of its own selection, provided that TranS1 shall have the right to control
such litigation. Whether or not Licensor chooses to participate in any such suit, Licensor shall fully cooperate at TranS1’s
expense, including without limitation testifying and making available relevant records, papers, information, samples, specimens,
and the like. In the event of a successful recovery, the proceeds shall be disbursed first to reimburse the Parties for costs incurred
in connection with the enforcement action. The balance shall be treated as Sales generated by TranS1 at the time of recovery.



 


9.4         Licensor’s Enforcement
Rights.  In the event that this Agreement is terminated by Licensor for material breach by TranS1 and Licensor
determines in its reasonable discretion that TranS1 failed prior to termination to take the appropriate course of action to enforce
the Licensed Technology in the Territory or otherwise abate the infringement thereof, or to defend any declaratory judgments seeking
to invalidate or hold the Licensed Patent Rights in the Territory unenforceable, Licensor shall thereafter have the right to bring
and prosecute such suits at its cost and expense through attorneys of its selection, in its own name, and all sums received or
recovered by Licensor in or by reason of such suits shall be retained by Licensor.


 


9.5         Marking. To the extent reasonably
practicable, TranS1 will mark, and cause each Affiliate and Sublicensee to mark, all Products with patent right notices that will
enable the Patent Rights to be enforced to their full extent in any country where the Products are made, used or sold.


 


10.         TERMINATION


 


10.1       Expiration of Minimums.
Upon completion of the Royalty Term, TranS1 shall continue to pay royalties to Licensor at the rate set forth in Section 4.4.1(e).
After Contract Year 8, no minimum royalty payments shall be due thereafter and Licensor shall have no further due diligence obligations.


 


10.2       Termination upon Limited
Market Release. TranS1 may elect, in its sole discretion, to terminate this Agreement on or before the due date for the payment
of the milestone for completion of the Limited Market Release. TranS1 may exercise this right by providing Licensor with written
notice of termination and a payment in the amount of $[***] in lieu of the $[***] payment otherwise payable upon completion of
the Limited Market Release. If TranS1 terminates pursuant to this Section 10.2, the Agreement shall be terminated effective upon
the delivery of such notice and the $[***] payment.

10.3       Termination for Cause or Bankruptcy.
Either party may terminate this Agreement upon or after the breach of any material provision of this Agreement by the other party
if such breach is not cured within (i) ten (10) days after receipt of express written notice thereof by the non-defaulting party
in the event of the breach of any payment obligation hereunder, or (ii) sixty (60) days after receipt of express written notice
thereof by the non-defaulting party in the event of breach of any other material provision of this Agreement. Any such termination
shall become effective at the end of the applicable cure period unless the breaching party has cured any such breach or default
prior to the expiration of such cure period (or, if such default is capable of being cured but cannot be cured within such applicable
60-day period, the breaching party has commenced and diligently continued actions to cure such default). In the event of a dispute
regarding alleged material breach, cure or termination of this Agreement which dispute is the subject of arbitration pursuant to
Section 13.3, termination shall be suspended pending the outcome of the arbitration.  Licensor may terminate this Agreement
in the event of (a) the filing by TranS1 of  a petition of bankruptcy, or a petition or answer seeking reorganization, readjustment
or rearrangement of its business or affairs under any law or governmental regulation relating to bankruptcy or insolvency; (b)
the appointment of a receiver of the business or for all or substantially all of the property of TranS1; (c) the making by TranS1
of an assignment or an attempted assignment for the benefit of its creditors; or (d) the institution by TranS1 of any proceedings
for the liquidation or winding up of its business or affairs (each of (a), (b), (c) and (d) shall be referred to herein as a “TranS1
Bankruptcy Event”).


 


10.4       Effect of Termination.


 


(a)         Termination of this Agreement
shall not relieve the parties of any obligation accruing prior to such termination, and the provisions of Sections 3.1(d), 6, 7.4,
8, 10.4, 11, and 13 shall survive the termination of this Agreement for any reason.


 


(b)         In the event that TranS1 terminates
this Agreement under Section 10.3 for breach by Licensor, then (i) each party shall return to the other all Confidential Information
of such other party, provided, however, that the parties may each retain a copy of such other party's Confidential Information
solely for archival purposes, and (ii) for a period of six (6) months thereafter, TranS1 (and its Affiliates and Sublicensees)
shall continue to be entitled to finish production of any Products which were in process at the time of termination, and TranS1
(and its Affiliates and Sublicensees) shall be entitled to sell all Products which were in inventory or in process at the time
of termination, so long as TranS1 (and its Affiliates and Sublicensees) continues to make the reports and pay the scheduled royalties
for said Sales as set forth in this Agreement, and (iii) except as specified in Section 10.4(a) and in this Section 10.4(b) or
with respect to any provision hereof that by its terms survives termination and any payment obligation that has accrued prior to
the date of termination, all rights and obligations of the parties under this Agreement shall terminate. If TranS1 has the right
to terminate this Agreement pursuant to Section 10.3 or if any third party asserts ownership of any portion of the Licensed Technology
and such assertion or any related claim results in material costs to TranS1 or in a material adverse effect on sales of Products,
TranS1 may, in addition to any other remedies, (x) elect to offset any amounts otherwise payable to Licensor against losses or
damages attributable to Licensor’s breach, (y) cease payments of minimum royalties, and (z) demand that Licensor renegotiate
any provisions of this Agreement reasonably affected by the breach or third party claim in which case Licensor shall negotiate
in good faith an appropriate amendment to the terms of this Agreement. In the event that Licensor terminates this Agreement under
Section 10.2, then (i) each party shall return to the other all Confidential Information of such other party; provided, however,
that the parties may each retain a copy of such other party's Confidential Information solely for archival purposes; (ii) TranS1
shall remain responsible for any payment accrued pursuant to Section 4.1 prior to the effective time of termination but shall have
no other payment or performance obligation thereafter, and (iii) except as specified in Section 10.4(a), in this Section 10.4(b),
or with respect to any provision hereof that by its terms survives termination, all rights and obligations of the parties under
this Agreement shall terminate.


 




    	16



    	 



    

 


(c)         In the event that Licensor
terminates this Agreement under Section 10.3, then (i) each party shall return to the other all Confidential Information of such
other party; provided, however, that the parties may each retain a copy of such other party's Confidential Information solely for
archival purposes; (ii) if such termination is due to a TranS1 Bankruptcy Event, then to the extent permitted by applicable law,
the successor in interest to TranS1’s rights under this Agreement shall be accountable to Licensor for all payments, including
past payments that may have been unpaid, and all future payments, according to the terms of this Agreement; (iii) if such termination
is not due to a TranS1 Bankruptcy Event, TranS1 shall immediately pay to Licensor all minimum royalties specified in Section 4.4.2(a)
for the remainder of the Royalty Term (provided that if the license has been converted to a non-exclusive license pursuant to Section
4.4.2(c), no minimum royalties are payable with respect to any period in which the license was non-exclusive or any period after
termination); and (iv) except as specified in Section 10.4(a), in this Section 10.4(c), or with respect to any provision hereof
that by its terms survives termination and any payment obligation that has accrued prior to the date of termination, all rights
and obligations of the parties under this Agreement shall terminate.


 


(d)         Upon termination of this Agreement
for any reason, all rights licensed or transferred by Licensor to TranS1 under this Agreement will revert to Licensor, and TranS1
agrees to execute and deliver all instruments necessary or desirable to re-vest those rights in Licensor.


 


(e)         In no event shall termination of
this Agreement release TranS1, or its Affiliates or Sublicensees from the obligation to pay any amounts that accrued or became
due on or before the effective date of such termination.

11.1       Indemnification. TranS1
shall defend, indemnify and hold Licensor harmless from all losses, liabilities, damages and expenses (including reasonable attorneys’
fees and costs) incurred as a result of any third party claim, demand, action or proceeding arising out of (i) the
manufacture, use, sale, performance or other exploitation of any Product by TranS1, or its Affiliates or its or their respective
Sublicensees or distributors, (ii) any breach of this Agreement by TranS1, or (iii) the gross negligence or willful misconduct
of TranS1 in the performance of its obligations under this Agreement, except in each case to the extent arising from the gross
negligence or willful misconduct of Licensor or the breach of this Agreement by Licensor. Licensor shall defend, indemnify and
hold TranS1 harmless from all losses, liabilities, damages and expenses (including reasonable attorneys’ fees and costs)

of Licensor’s rights to use or practice the Licensed Know-How or processes claimed in the Licensed Patent Rights in

11.2       Procedure. The party
seeking indemnity (“Indemnitee”) promptly shall notify the other (“Indemnitor”) of any liability or action
in respect of which Indemnitee intends to claim indemnification. The Indemnitor shall have the right to participate jointly with
the Indemnitee in the Indemnitee's defense, settlement or other disposition of any indemnity claim. With respect to any indemnity
claim relating solely to the payment of money damages and which could not result in the Indemnitee's becoming subject to injunctive
or other equitable relief or otherwise adversely affect the business of the Indemnitee in any manner, and as to which the Indemnitor
shall have acknowledged in writing the obligation to indemnify the Indemnitee hereunder, the Indemnitor shall have the sole right
to defend, settle or otherwise dispose of such indemnity claim, on such terms as the Indemnitor, in its discretion, shall deem
appropriate; provided that the Indemnitor shall provide reasonable evidence of its ability to pay any damages claimed and with
respect to any such settlement shall obtain the written release of the Indemnitee from the indemnity claim. The Indemnitor shall
obtain the written consent of the Indemnitee prior to ceasing to defend, settling or otherwise disposing of any Indemnity Claim
if as a result thereof the Indemnitee would become subject to injunctive or other equitable relief or the business of the Indemnitee
would be adversely affected in any manner.


 


11.3       Insurance. TranS1 shall
obtain and maintain product liability and general liability insurance which is sufficient to meaningfully protect Licensor as required
by the indemnification provisions herein (including naming Licensor as an additional insured), and shall require each of its authorized
Affiliates and Sublicensees to have such insurance. Evidence of the existence and sufficiency of such insurance shall be provided
to Licensor upon request. TranS1 shall provide Licensor with at least fifteen (15) days written notice prior to any cancelation,
non-renewal or material change in such insurance.


 


12.         FORCE
MAJEURE


 


Neither party shall be held liable or responsible to the other
party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term
of this Agreement to the extent, and for so long as, such failure or delay is caused by or results from causes beyond the reasonable
control of the affected party (and such affected party takes reasonable efforts to remove the condition), including but not limited
to fire, floods, embargoes, war, acts of war (whether war be declared or not), acts of terrorism, insurrections, riots, civil commotions,
strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any governmental authority
