12 box 2, registered in the register of legal entities (Leuven) under number 0471.340.123.



“Data Controller”has the meaning as defined in article ‎7.1.



“Warrant”means
a subscription right regarding a newly to be issued Share in the Company, attributed in accordance with the issuance conditions
mentioned in this Plan.



“Warrant Holder”
means a physical person or a legal entity to whom (i) the Company has attributed Warrants and who/that has completely or partially
accepted these Warrants in a timely manner, or (ii) Warrants were transferred in accordance with the terms and conditions
of this Plan.



| | 2 | Object of the Plan
| | - | ------------------



The exercise of a Warrant entitles
the Warrant Holder to subscribe to one (1) Share.



In the framework of this Plan a
maximum of five million five hundred and five thousand four hundred seventy-seven (5,505,477) Warrants can be issued. Consequently,
the Company can issue up to five million five hundred and five thousand four hundred seventy-seven (5,505,477) Shares as a result
of the exercise of the Warrants.



| | 3 | Offering and acceptance of the Warrants
| | - | ---------------------------------------



The Warrants can be offered until
twelve (12) months after the issuance of the Warrants (included) by the Board of Directors to the CEO (Eduardo Bravo) and the independent
directors of the Company (with application of the conflict of interest procedure set out in article 523 of the Companies Code and,
as far as the independent directors are concerned, after approval by the shareholders’ meeting) and to employees of the Company
or a Subsidiary.



Warrants will primarily be granted
to employees of the Company or its Subsidiaries. The Board of Directors will make sure that the number of Beneficiaries who are
not an employee of the Company or its Subsidiaries only will make up a minority of the total number of Beneficiaries.



The total number of Beneficiaries
shall, in any event, be lower than 150.



Each Beneficiary has the possibility
to accept or to refuse the individual offering of Warrants by the Board of Directors. The acceptance of Warrants needs to be done
in writing by checking the option acceptance, mentioning the number of accepted Warrants, on the answer form prepared for these
purposes. The answer form must be completed and signed by the Beneficiary and be delivered to the Company prior to the relevant
date stated therein. If the Beneficiary does not accept in writing the offer of Warrants prior to the ultimate date stated in the
answer form, he/she/it is deemed to have refused the offer of Warrants.



Notwithstanding the foregoing,
the offering and acceptance of Warrants may also be included in a specific warrant agreement, or inserted in another agreement
signed by the Company and the Beneficiary.



Offered Warrants that are refused
by the Beneficiary or that are not timely accepted in writing, shall become automatically null and void and cannot be offered again.

| | 4 | Terms and conditions of the Warrants
| | - | ------------------------------------



| | 4.1 | Warrant price
| | --- | -------------



The Warrants are granted free of
charge.



| | 4.2 | Vesting
| | --- | -------



When granting the Warrants, the
Board of Directors may freely decide if, when and to which extent the attributed Warrants will definitively vest for the Warrant
Holders.



Unless the Board of Directors (after
approval by the shareholders’ meeting regarding any Warrants granted to independent directors) decides otherwise at the time
of the grant of the Warrants and subject to the End of the Cooperation, (i) 1/3rd of the Warrants granted to a
Warrant Holder will be deemed definitively vested for the latter on the first anniversary of the granting of the Warrants and (ii) 1/24th
of the remaining 2/3rd of the Warrants granted to such Warrant Holder will definitively vest on the last day of each
of the 24 months following the month of the first anniversary of the granting of the Warrants.



The Board of Directors and/or the
CEO acting together with the Chairman of the Company’s Nomination and Remuneration Committee (subject to the approval by
the shareholders’ meeting regarding any Warrants granted to independent directors) can also decide to modify the vesting
conditions after the granting of Warrants, provided that the rights of the Warrant Holder may not be restricted without the latter’s
consent and that only the Board of Directors can modify the vesting conditions in case of Warrants granted to the CEO. Prior to
the End of the Cooperation, the Board of Directors or the CEO acting together with the Chairman of the Company’s Nomination
and Remuneration Committee will, for example, in mutual agreement with the Warrant Holder, be able to allow that all or a part
of the Warrants that have not yet definitively vested at the End of the Cooperation, are definitively vested.



| | 4.3 | Exercise price
| | --- | --------------



Unless the Board of Directors at
the time of the grant of the Warrant determines a higher exercise price, the exercise price of a Warrant will be equal to the lowest
of the following prices:



| | · | the last closing price of the TiGenix share on Euronext Brussels prior to the date on which the
Warrant is offered; or
| | - | ----------------------------------------------------------------------------------------------------------------------



| | · | the average closing price of the TiGenix share on Euronext Brussels over the 30 day period preceding
the date on which the Warrant is offered,
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------



it being understood that, for Beneficiaries
of the Plan that are not employees of the Company or its Subsidiaries, the exercise price cannot be lower than the average closing
price of the TiGenix share on Euronext Brussels over the 30 day period preceding the date of issuance of the Warrants.



The exercise price may never be
below the par value of the existing shares at the date on which the Warrants were issued (being EUR 0.10).



Upon exercise, the portion of the
exercise price up to the par value of the existing shares (being EUR 0.10) needs to be recorded as capital. The portion of the
exercise price exceeding the par value of the existing shares needs to be recorded on a separate account unavailable for distribution
called “Issuance premiums”.

| | 4.4 | Duration of the Warrants
| | --- | ------------------------



The Warrants have a duration of
ten (10) years as from the date of the Board of Directors’ meeting deciding on the issuance of the Warrants.



| | 4.5 | Nature
| | --- | ------



The Warrants are and will remain
registered. They will be recorded in the register of warrant holders, which will be kept by the Company at the registered office,
mentioning the identity of each Warrant Holder and the number of Warrants held by such holder.



| | 4.6 | Modification of the Company’s capital structure
| | --- | -----------------------------------------------



Contrary to article 501 of the
Companies Code and without prejudice to the exceptions provided for by law, the Company shall retain the right to take decisions
and close transactions that could have an influence on its capital, the distribution of profit or the liquidation bonuses, or that
could possibly have another influence on the Warrant Holders’ rights, except if such decisions or transactions only are aimed
at diminishing the Warrant Holders’ benefits.



In case the rights of the Warrant
Holder are affected by such decision or transaction, the Warrant Holder will not be entitled to a modification of the exercise
price or the exercise conditions, nor to any other form of financial or other compensation. The Board of Directors may, at its
own discretion, make amendments to the number of Shares to which one Warrant relates and/or to the exercise price, however. As
soon as reasonably possible, the Company will inform the Warrant Holder of any such amendment by way of a written notification.



In case of merger, split and/or
share split, the subscription rights relating to the Warrants outstanding on the date of such transaction, as well as the exercise
price relating to these Warrants, will be modified in accordance with the exchange ratio used for the existing shares in the Company
pursuant to the merger, split and/or share split, without taking into account fractions.



| | 5 | End of the Cooperation - Transfer of the Warrants
| | - | -------------------------------------------------



| | 5.1 | End of the Cooperation
| | --- | ----------------------



At the End of the Cooperation of
a Warrant Holder, all Warrants that have been granted to the concerned Warrant Holder but that have not yet vested in accordance

null and void, unless, prior to the End of the Cooperation, it is expressly agreed otherwise in writing between the Company and
the Warrant Holder in accordance with article ‎4.2.



| | 5.2 | Member of the group
| | --- | -------------------



Unless the Board of Directors decides
otherwise, all Warrants that have not yet vested in accordance with article ‎4.2

or of which the Warrant Holder is an employee or consultant, is no longer controlled (as defined in article 5, §1 of
the Companies Code) by the Company.








ENGLISH TRANSLATION FOR INFORMATION PURPOSES ONLY




| | 5.3 | Decease
| | --- | -------



If a Warrant Holder deceases, all
Warrants of the deceased Warrant Holder that have vested already in accordance with article ‎4.2
of this Plan at the time of his/her decease, are transferred to the Rightful Claimants of the Warrant Holder, and they will be
exercisable at the ordinary moment and in accordance with the modalities defined in these issuance conditions. All Warrants that
have not yet vested in accordance with article ‎4.2
of this Plan at the time of the decease of the Warrant Holder shall become automatically null and void.



| | 5.4 | Transferability
| | --- | ---------------



Unless the Board of Directors decides
otherwise, the Warrants are not transferable inter vivos once they have been granted to a Beneficiary, and may not be pledged
or encumbered in any other way. Warrants that have been pledged or encumbered in violation of the preceding, shall become automatically
null and void.



| | 6 | Exercise of the Warrants
| | - | ------------------------



| | 6.1 | Exercisability of the Warrants
| | --- | ------------------------------



| | 6.1.1 | The Warrants can only be exercised by the Warrant Holder if they have definitively vested pursuant
to article ‎4.2. The Warrants that consequently
become exercisable, must be exercised in accordance with the exercise modalities provided for in article ‎6
and provided that, if applicable, the “Dealing Code” of the Company is complied with. In deviation from the foregoing,
Warrants granted to persons falling within the scope of application of the first paragraph of article 520ter of the Belgian Companies
Code, can only be exercised after expiry of a period of three (3) years starting on the date on which such Warrants were granted,
unless the Board of Directors (after approval by the shareholders’ meeting regarding any Warrants granted to independent
directors) decides otherwise at the time of or after the grant of the Warrants.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.1.2 | In case the Warrants, that are not yet exercisable in accordance with the terms and conditions
of the Plan, become prematurely exercisable in accordance with article 501 of the Companies Code and are effectively exercised
in accordance with such article, the Shares that are issued as a result of such exercise will not be transferable until the moment
that the Warrants would have been exercisable pursuant to the terms and conditions of the Plan, unless express approval is obtained
from the Company.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.1.3 | In case Warrants that are effectively vested would not be exercised at the latest on the last day
of the last Exercise Period during the duration of the Warrants as set out in article ‎4.4,
such Warrants shall become automatically null and void.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.2 | Exercise Periods
| | --- | ----------------



Without prejudice to article ‎6.1.1,
the Warrants can be exercised until the end of the duration as set out in article ‎4.4
during the following “Exercise Periods” of each year that they are validly exercisable:



| | · | 1 May until 31 May (included); and
| | - | ----------------------------------








ENGLISH TRANSLATION FOR INFORMATION PURPOSES ONLY




| | · | 1 November until 30 November (included).
| | - | ----------------------------------------



Within the legal boundaries, the
Board of Directors can decide to amend the Exercise Periods without being able to shorten them, however. For example, in order
to avoid insider trading, the Board of Directors can decide to introduce closed periods, during which the Warrants cannot be exercised.
If such closed periods would fall within the aforementioned Exercise Periods, the Board of Directors can determine one or more
additional Exercise Periods as compensation and communicate the new Exercise Periods in writing to the Warrant Holders.



Warrants cannot be exercised and/or
the Shares cannot be traded in the event that the Warrant Holder has inside information. In accordance with article 2, 14°
of the Law of 2 August 2002 on the supervision of the financial sector and on financial services, “inside information”
means any information of a precise nature which has not been made public, relating, directly or indirectly, to the Company or to
one or more financial instruments issued by the Company and which, if it were made public, would be likely to have a significant
effect on the prices of those financial instruments or derivatives thereof.



Warrant Holders whose exercise
rights are limited as a consequence of the conditions of this Plan or of the “Dealing Code” of the Company, are never
entitled to any indemnification or compensation from the Company.



The exercise of the Warrants at
the exercise price is unconditional.



| | 6.3 | Change of control
| | --- | -----------------



| | 6.3.1 | In the event of a change of control (as defined in article 5, §1 of the Companies Code)
over the Company, the Board of Directors has the power to shorten, in deviation of articles ‎6.1.1
and ‎6.2, the Exercise Periods provided that
it shall offer the Warrant Holder a term of at least one (1) month in which the Warrant Holder can exercise his/her/its Warrants,
provided that, if applicable, the “Dealing Code” of the Company is complied with.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.3.2 | In the event of a change of control (as defined in article 5, §1 of the Companies Code)
over a Subsidiary, the Board of Directors has the power to shorten, in deviation of articles ‎6.1.1
and ‎6.2, the Exercise Periods of the Warrants
that are held by Warrant Holders who are an employee, director or consultant of such Subsidiary, provided that it shall offer the
relevant Warrant Holder a term of at least one (1) month in which the relevant Warrant Holder can exercise his/her/its Warrants,
provided that, if applicable, (i) the Board of Directors decided to deviate from article ‎5.2,
and (ii)the “Dealing Code” of the Company is complied with.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6.3.3 | Notwithstanding any other provision of this Plan, any such reduction of the Exercise Periods shall
be accompanied by the right of each relevant Warrant Holder, who is not yet at the End of the Cooperation at that time, to exercise
immediately all of the Warrants granted to and accepted by him and that have not yet expired (including Warrants that have not
yet vested definitively in accordance with article ‎4.2).
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | --- | ---------------------------------



The transfer restrictions provided
for by article ‎5.4 of this Plan are not applicable
to transfers of Warrants pursuant to a public takeover bid or a public squeeze-out bid on the securities in the Company.



| | 6.5 | Exercise restrictions
| | --- | ---------------------



The Board of Directors may impose
additional restrictions and conditions to the exercisability of the Warrants at the time the Board of Directors grants them. At
the moment of granting, the Board of Directors will, for example, be able to determine that the Warrants that are definitively
vested only can be exercised (i) after expiry of a certain period after the grant of the Warrants or (ii) after the satisfaction
(or waiver by the Company) of certain conditions precedent (such as, for example, the achievement of certain milestones by the
Company) as may be determined by the Board of Directors.



| | 6.6 | Exercise modalities
| | --- | -------------------



In order to exercise a Warrant,
at the latest on the last day of the last Exercise Period during the duration of the Warrants, the Company needs to receive a written
notice of exercise of the Warrants. The notification shall take place by registered mail, against receipt confirmation, or by personal
delivery to the Board of Directors or the secretary of the Company at the registered office of the Company. The notice shall be
signed by the Warrant Holder (or, if applicable, his/her Rightful Claimant(s)) and must explicitly state the number of Warrants
being exercised and the number of Shares consequently being subscribed to. If the Warrants are exercised by one or more Rightful
Claimants, the notice of exercise needs to be accompanied by an appropriate proof of the right of this person or these persons
to exercise the Warrants.



The full payment of the exercise
price of the exercised Warrants needs to be deposited by wire transfer on a blocked account of the Company of which the bank account
number is communicated by the Board of Directors or the CEO. This payment shall take place within ten (10) business days after
having received the aforementioned communication of the bank account number from the Board of Directors or the CEO, or within ten
(10) business days after the date of the notice of exercise in the event that the bank account number concerned has already previously
been communicated by the Board of Directors or the CEO.



| | 6.7 | Issuance of Shares
| | --- | ------------------



The Company will only be obliged
to issue Shares as a result of the exercise of the Warrants if the conditions set out in article ‎6
have been fulfilled.



As soon as the exercise conditions
have been fulfilled, the concerned new Shares will be issued, taking the required administrative formalities into account. To this
effect, the Board of Directors or two directors acting jointly will timely, and at least once per quarter, acknowledge before a
notary public that the capital was increased in accordance with article 591 of the Companies Code.



The Shares that are issued as a
result of the exercise of the Warrants will be common shares and will be fully profit sharing as from the beginning of the business
year during which the Shares are issued and the following business years.








ENGLISH TRANSLATION FOR INFORMATION PURPOSES ONLY




At the option of the Company, and
to the extent legally and practically possible, the Shares shall be delivered as registered shares (recorded in the name of the
Warrant Holder (or, if applicable, his/her Rightful Claimant(s)) in the register of registered shares in the Company), or in dematerialised
form. In case the Warrant Holder (or, if applicable, his/her Rightful Claimant(s)) explicitly indicates in his/her/its notice of
exercise the form in which he/she/it wants to see the Shares delivered, the Company will deliver the Shares in the form requested
to the extent legally and practically possible and to the extent that this would be in accordance with the articles of association
of the Company. The Company will inform the concerned Warrant Holder (or, if applicable, his/her Rightful Claimant(s)) of the form
of delivery in due time.

| | --- | ---------

Shares shall be subject to the applicable consents, legislations and regulations as applicable at that point in time in Belgium
or elsewhere. The Warrant Holder shall be responsible for complying with the necessary requirements in view of obtaining the consents
required or avoiding that any consents would be required.

| | --- | -----------------------



The Shares acquired pursuant to
the exercise of the Warrants will be subject to the applicable provisions of the articles of association of the Company.

this Plan on the regulated market of Euronext Brussels.



| | 6.11 | Rights as shareholders
| | ---- | ----------------------



The Warrant Holder does not have
the rights and privileges of a shareholder regarding the Shares, to which the Warrants give right, until the date these Shares
are issued by the Company to the Warrant Holder. Once the Shares have been issued by the Company to the Warrant Holder, the latter
enjoys, in his/her/its capacity as shareholder of the Company, the same rights as the other shareholders.



| | 7 | Privacy and processing of Personal Data

of the Plan and the management of the register of warrant holders and the register of registered shares, personal information about
