in the name of MSB, except that TiGenix shall have the right to credit the amounts incurred with respect to the Prosecution and
Maintenance of such Licensed Patent against the amounts due pursuant to Paragraph II(a) of the Financial Exhibit with respect
to Royalty Products Covered by such Licensed Patent.



(b)Update of Exhibits A and B. If a Party reasonably believes that either Exhibit A(Issued Licensed Patents)
or Exhibit B (Pending Licensed Patents) should be updated to include one or more additional Patents, then such Party shall
provide the other Party notice setting out for the basis for such belief and, subject to the Parties agreeing in writing, Exhibit
A and/or Exhibit B, as applicable shall be appropriately updated.



(c)Future Inventions. For the avoidance of any doubt, each Party is and remains free to Prosecute and Maintain Patents
or other Intellectual Property Rights that it owns or otherwise has the appropriate rights to, including but not limited to independent
developments and improvements of the Licensed Patents.



(d)Enforcement.



(i)Notice. Subject to the provisions of this Section 4(d), in the event that either Party reasonably believes that
any Licensed Patent (A) is being infringed by a Third Party’s product or process comprising allogenic adipose-derived MSCs
for the Field in the Territory that is Covered by a Valid Claim (such product, a “Competing Product” and such
infringement, a “Competing Infringement”) or (B) is subject to a declaratory judgment action arising from Competing
Infringement, such Party shall promptly notify the other Party.



(ii)Enforcement Actions.



(1)As between the Parties, MSB (itself or through one or more other Entities acting under its authority) shall have the right
(but not the obligation) to initiate and control at its expense an action alleging infringement of a Licensed Patent with respect
to any Competing Infringement (any, a “Competing Enforcement Action”).



10***Confidential Treatment Requested


EXECUTION COPY


(2)TiGenix shall have the right (but not the obligation) to initiate and control at its expense a Competing Enforcement Action
in the event that (A) MSB fails to commence any Competing Enforcement Action within sixty (60) days after the notice described
in Section 4(d)(i) (or within such shorter period as may be necessary to initiate and maintain full enforcement rights under such
Competing Enforcement Action within the statutory or other binding time limitations), (B) there are no Patents (other than Licensed
Patents) that TiGenix, its Affiliate or Sublicensee could reasonably enforce against such Competing Product, and (C) there is
a reasonable likelihood that a court establishes the Competing Infringement; provided that “a reasonable likelihood”
in this context means that it is more likely than not that a court deciding on the merits would establish a Competing Infringement
without materially adversely affecting the License Patent; and provided that, in the event the Parties fail to agree amongst themselves
on whether there is such reasonable likelihood within a period of thirty (30) days after the notice described in Section 4(d)(i)
(or within such shorter period as may be necessary to initiate and maintain full enforcement rights under such an action within
the statutory or other binding time limitations), such matter shall be referred for resolution to one (or three) independent patent
attorney(s) practicing in a country where the Competing Infringement is occurring, who should provide a reasoned opinion on the
issue as a matter of urgency, and in any event no later than thirty (30) days after such referral (or within such shorter period
as may be necessary to initiate and maintain full enforcement rights under such an action within the statutory or other binding
time limitations). TiGenix shall provide MSB with an opportunity to make suggestions and comments with regard to such a Competing
Enforcement Action controlled by TiGenix and shall consider and incorporate, in its reasonable discretion, such suggestions and
comments.



(iii)Cooperation. The Party controlling any Competing Enforcement Action in accordance with this Section 4(d) (the “Enforcing
Party”) shall keep the other Party reasonably informed of the progress of any such Competing Enforcement Action, and
such other Party shall have the right to participate with counsel of its own choice at its own expense without prejudice to Section
4(c)(iv) but will not be an Enforcing Party. In any event, the other Party shall reasonably cooperate with the Enforcing Party,
including providing information and materials, at the Enforcing Party’s request and expense. If TiGenix is the Enforcing
Party, MSB shall join any Competing Enforcement Action as a party-plaintiff, upon TiGenix’s request and expense, if and
to the extent such joinder is necessary to fully enforce rights under, and obtain remedies in respect of, the Competing Infringement.
The Enforcing Party shall also have the right to control settlement of the Competing Enforcement Action; provided, however, no
settlement shall be entered into without the consent of the other Party if such settlement would have a material adverse effect
on the interests of the other Party, which consent shall not be unreasonably withheld.



(iv)Costs and Recoveries. Any recovery received as a result of any Competing Enforcement Action pursuant to this Section
4(d) shall be used first to reimburse the Enforcing Party for the costs and expenses (including court, attorneys’ and professional
fees) incurred in connection with such Competing Enforcement Action. The remainder of the recovery attributable to the Competing
Infringement shall be paid as follows: (A) if MSB is the Enforcing Party: [***]% of such remainder of the recovery shall be paid
to TiGenix and [***]% shall be



11***Confidential Treatment Requested


EXECUTION COPY


paid
to MSB or (B) if TiGenix is the Enforcing Party: [***]% of such remainder of the recovery shall be paid to TiGenix and [***]%
shall be paid to MSB.



(e)Patent Marking. TiGenix shall mark (or cause to be marked) Royalty Product sold or offered for sale with appropriate
Licensed Patent numbers or indicia at MSB’s request, to the extent permitted by Applicable Law, it being understood that
(i) TiGenix shall only be required to do so in those countries in which such notices impact recoveries of damages or remedies
available with respect to infringements of Licensed Patents and (ii) in no event TiGenix shall have to mark (or cause to be marked)
more than what is necessary and customary for achieving said purpose in such country.



(f)Patent Assignment. In the event that MSB elects to assign or transfer any rights to or under any Licensed Patent,
MSB shall ensure that each assignment or other transfer of any Licensed Patent shall be expressly subject to the terms and conditions
of this Agreement, such that the rights and obligations (including the license) under this Agreement are opposable towards any
Third Party to whom such Licensed Patent is assigned or transferred.



(g)Registration of the License. TiGenix shall have the right (but not the obligation), at its cost, to record with
any and all of the relevant intellectual property (including, patent) offices, TiGenix deems appropriate, throughout the Territory,
the rights and obligations under this Agreement, and MSB shall reasonably assist TiGenix in connection therewith, at TiGenix’s
cost; for the avoidance of doubt, nothing in this Section 4.(g) alters MSB’s obligations under Section 4.(f).

the extent such disclosure is absolutely necessary and limited to the furthest extent possible, in the following situations:



(i)enforcing its rights or the obligations of the other Party under, or arising out of, this Agreement, in accordance with
Section 10(b) of this Agreement;



(ii)complying with Applicable Laws and regulations promulgated by security exchanges, court order or administrative subpoenas

that reasonably protect the confidentiality thereof, or to the extent necessary to comply with the terms of agreements with Third
Parties, or to the extent required by Applicable Law or the rules of any applicable securities exchange. Notwithstanding the foregoing,
the Parties agree to issue the joint press release attached hereto as Exhibit E announcing the execution and the material
terms of this Agreement on the Effective Date ([***]); thereafter, MSB and TiGenix may each disclose to Third Parties the information
contained in such press release without the need for further approval by the other.



(ii)Publicity Review. To the extent that any other disclosure with respect to matters within the scope of this Agreement
is required by Applicable Law or the rules of recognized stock exchanges with respect to a Party, such Party shall provide the
other Party with at least 72 hours advanced written notice to review and comment on such statement.



8.JOCC / NEGOTIATIONS FOR OTHER RIGHTS / NO CHALLENGE.



(a)Joint Oversight/Cooperation Committee. Promptly after the Effective Date, TiGenix and MSB shall establish a joint
oversight/cooperation committee (the “JOCC”) to (i) oversee the interactions of the Parties under this Agreement,
(ii) cooperate to avoid disputes between the Parties under this Agreement, (iii) in the event that a Licensed Patent is infringed
by a product for the Field in the Territory, which product is not comprised of allogenic adipose-derived MSCs and if requested
by TiGenix, discuss the possibility of MSB enforcing such Licensed Patent against such infringement, and (iv) discuss those certain
matters described in this Section 8. The JOCC shall consist of an equal number of representatives from each of MSB and TiGenix,
and unless otherwise agreed such number shall be two (2) representatives appointed by each of MSB and TiGenix. Either Party may
replace its respective representative(s) to the JOCC at any time with prior notice to the other Party, provided that such replacement
is of comparable authority and scope of responsibility within that Party’s organization as the individual he or she is replacing,
but may have different area of responsibility. The JOCC shall meet at least once every six (6) months or more often as either
Party may reasonably request at which meetings the JOCC shall discuss the interactions between the Parties hereunder and



17***Confidential Treatment Requested


EXECUTION COPY


attempt
to address any concerns of either Party within the context of the terms and conditions of this Agreement.



(b)Other Rights to the Licensed Patents. If TiGenix (or any Entity under authority of TiGenix) has (i) filed investigational
drug application (IND) or equivalent filing necessary to initiate a phase three (3) or equivalent pivotal human clinical trial
with the applicable Regulatory Authority, which IND or filing is effective, for (A) the Cx 601 Product for any indication outside
of the Field (each, a “New Indication”) or (B) another product (other than the Cx 601 Product) comprising allogeneic
adipose-derived MSCs for treatment of any indication (any, a “New Product”), (ii) received a term sheet from
a Third Party for the development or commercialization of (A) the Cx 601 Product for a New Indication in the Territory or (B)
a New Product, or (iii) with respect to any Patent owned or controlled by MSB, the period to conduct a Challenge (as defined in
Section (c)), including oppose, file an interference or conduct any pre-issuance challenge, with respect to such Patent has started
running (each, a “Pre-Issued MSB Patent”), then TiGenix has the right (but not the obligation) to notify a
written request to the JOCC (which request shall identify the particular product, the indication and the corresponding Patent(s)
owned or controlled by MSB that TiGenix would like to obtain a license for (any, a “Negotiation Request”) and
which request shall have to be treated with outmost confidentiality by MSB and its Affiliates and the contents of which shall
not be published or otherwise disclosed by MSB and its Affiliates, nor used by MSB and its Affiliates for any purpose other than
the assessment of TiGenix’s New Indication or New Product under this Section 8(b)), and unless MSB notifies TiGenix within
thirty (30) days of the Negotiation Request that MSB has determined in good faith that the proposed grant would compete with any
product then planned, under development or being marketed by or under authority of MSB or its Affiliate, or is of future commercial
interest to MSB or its Affiliate, or is otherwise prohibited from making such a grant (any a “Denial Notice”),
the JOCC shall discuss in good faith (including meeting at least one time specifically for such discussions) the possibility that
MSB would grant appropriate licenses/covenants not to sue under the Licensed Patents and/or other MSB Patents, including Pre-Issued
MSB Patent and the terms and conditions of such grant. If MSB provides a Denial Notice or the Parties do not enter into a definitive
agreement (whether as an amendment to this Agreement or otherwise) for any reason within sixty (60) days of the Negotiation Request
(this period being extendable upon the written agreement of the Parties), then neither Party shall have any further obligation
or liability with respect to such Negotiation Request (the date thereof, the “8(b) Expiration Date”). To avoid
any doubt, a decision by TiGenix not to make a Negotiation Request shall not constitute a breach under this Agreement.



(c)Limited cause for termination due to a Challenge. During the term of this Agreement and with respect to the Licensed
Patents, TiGenix agrees (and shall cause each of its Affiliate and Sublicensees to agree) (A) absent a Negotiation Request with
respect to a particular Patent pursuant to Section 8(b) not to (i) challenge in any court action or proceeding, or before any
patent office, the validity, patentability, enforceability, scope or non-infringement of such Patent, (ii) initiate a reexamination
of such Patent or otherwise submit any materials for such purposes, or (iii) assist any Third Party to conduct any of the foregoing
activities (each, a “Challenge”) or (B) in the case of a Negotiation Request with respect to a particular Patent



18***Confidential Treatment Requested


EXECUTION COPY


pursuant
to Section 8(b), not to conduct a Challenge at any time prior to the 8(b) Expiration Date, unless the time limitations in Section
8(b) would result in TiGenix being time barred for conducting a Challenge, including in particular an opposition, interference
or other challenge, with respect to such Patent.



Notwithstanding
these limited exceptions (A) and (B), TiGenix (or its Affiliate or Sublicensee) shall have and retain any and all right to conduct
a Challenge, including with respect to Licensed Patents and Pre-Issued MSB Patents, by way of a Reactive Challenge. “Reactive
Challenge” means a Challenge of a Patent that MSB has asserted or threatened in writing to assert (either itself, an
Affiliate or via a Third Party) against any product of TiGenix, its Affiliate or Sublicensee.



Nothing
in this Section 8(c) shall prohibit nor limit in any way TiGenix’s right to conduct a Challenge against a Patent of MSB
other than a Licensed Patent, provided that TiGenix has provided the Challenge Notice (as defined below) with respect thereto.



TiGenix
and MSB agree that the end result of any Challenge, other than a Reactive Challenge, shall not affect the payments to Mesoblast
Sàrl as set forth in Exhibit C, including the payment of royalties for Royalty Product under this Agreement, to the extent
that there is still a Valid Claim Covering said Royalty Product.



Except
in case of a Reactive Challenge, TiGenix shall notify MSB at least thirty (30) days prior to initiating a Challenge (each, a “Challenge
Notice”) whereby TiGenix, its Affiliate and Sublicensees shall not initiate a Challenge until each of the 8(b) Expiration
Date, if applicable, and the Challenge Notice have occurred.



MSB
shall notify TiGenix at least thirty (30) days prior to asserting a Patent against TiGenix, its Affiliates and/or its Sublicensees
(each, an “Assertion Notice”) and MSB (itself, an Affiliate or a Third Party on behalf thereof) shall not assert
such Patent until the Assertion Notice has occurred.



9.TERM AND TERMINATION.



(a)Term. This Agreement shall become effective as of the Effective Date and, unless earlier terminated pursuant to
the other provisions of this Section 9, shall continue in full force from and after the Effective Date until the expiration of
the Royalty Term as set forth in the Financial Exhibit (the “Term”).

(or any Entity acting on behalf of the Other Party or its Affiliate) materially breaches this Agreement, including any breach
of the representations and



19***Confidential Treatment Requested


EXECUTION COPY


warranties
under Section 5, and such breach shall have continued for ninety (90) days after notice thereof was provided to the Other Party.
Any such termination shall become effective upon notice thereof at the end of such ninety (90) day period unless the Other Party
has cured any such breach prior to the expiration of the ninety (90) day period; (B) In case TiGenix is of the opinion that there
is no Valid Claim Covering the Cx 601 Product in a given country at a given time as a result of the fact that the only Valid Claims
then Covering the Cx 601 Product (W) have been invalidated as a result of a Challenge in accordance with Section 8(c), (X) have
been invalidated by a Third Party, (Y) were previously pending Licensed Patents which when issued, issued more narrowly than prosecuted,
or (Z) have been abandoned by MSB and not Prosecuted and Maintained by TiGenix pursuant to Section 4(a), and on that basis it
is not obligated to pay royalties for the Net Sales in that country, it may notify MSB and if MSB disagrees, the Parties shall
refer the matter to the JOCC for resolution first. If the JOCC does not succeed in resolving the disagreement within three (3)
months, the Parties shall refer their dispute for resolution pursuant to Section 10(b). MSB shall not have the right to terminate
the Agreement in the case of (B) as long as (I) the matter is pending before the JOCC and/or pursuant to Section 10(b) and (II) TiGenix
pays into an escrow account the amount that would have otherwise been payable to MSB for such Cx 601 Product had it been a Royalty
Product. In such event, if the matter is resolved in the favor of TiGenix, then TiGenix shall receive the amounts set forth in
such escrow account or if the matter is resolved in the favor of MSB, then MSB shall receive the amounts set forth in such escrow
account (in each case together with any interest at the rate set forth in Exhibit C, Paragraph II(f)). Any termination based on
the situation in this Section 9(c)(i)(B), for breach or otherwise, shall in any event be limited to the country in question
and not affect the license in the remainder of the Territory.



(ii)MSB may terminate this Agreement upon delivery of written notice to TiGenix in the event that (A) TiGenix files in any
court or agency pursuant to any statute or regulation of any jurisdiction a petition in bankruptcy or insolvency or for reorganization
or similar arrangement for the benefit of creditors or for the appointment of a receiver or trustee of such other Party or its
assets, or (B) TiGenix makes an assignment of substantially all of its assets for the benefit of its creditors.



(d)Termination for Failure under Section 4(h). Either Party may terminate this Agreement in its entirety immediately
upon notice if the other Party does not fulfill its obligations under Section 4(h) in its entirety.



(e)General Effects of Expiration or Termination.

which, at the time of such expiration or termination, has already accrued to the other Party or which is attributable to a period
prior to such expiration or termination.



(ii)Notwithstanding anything herein to the contrary, termination of this Agreement by a Party shall be without prejudice to
other remedies such Party may have at law or equity.

Financial Exhibit Paragraphs II(c), (d), (e) and (f) (each for three (3) years after termination or expiration). Except as otherwise

                                         to allow TiGenix to comply with the terms and conditions of this Agreement. For each
                                         Selling Party, TiGenix shall obtain audit rights and perform (or have performed) audits
                                         at the Selling Parties. If MSB has substantiated reasons to believe that a Selling Party
                                         is not accurately reporting Net Sales to TiGenix, it shall be entitled to ask TiGenix
                                         to perform an audit of the Selling Party’s books and records. TiGenix shall provide
                                         MSB with a copy of the findings of such audit. If the inspection and audit shows no underpayment
                                         of more than ten percent (10%) of the amount due for the applicable period, the costs
                                         of such audit shall be borne entirely by MSB. If it does, TiGenix shall pay the cost
                                         of such audit. TiGenix shall promptly pay to Mesoblast Sàrl the amount of any
                                         underpayment revealed by an examination and review. No more than one audit of a Selling
                                         Party per calendar year shall be conducted under this Agreement.
