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



| | 7.1.1 | The Bidder acknowledges that on 11 October 2017 the Target approved the accelerated vesting of
the outstanding unvested Warrants held by all holders of Warrants other than the independent directors in accordance with article
4.2 of the applicable plans for such Warrants (the "Warrant Plans"). Such accelerated vesting is conditional on
the start of the First Acceptance Period of the Bid and will allow more holders of Warrants to tender their Warrants (or the Shares
received as a result of the exercise thereof) into the Bid. According to the terms and conditions of the Warrant Plans, the transfer
restrictions applicable to the Warrants do not apply to tenders of Warrants (or the Shares received as a result of the exercise
thereof) into the Bid.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7.1.2 | The Bidder furthermore acknowledges that on 11 October 2017 the Target approved the creation of
an exceptional exercise period (the "Exceptional Exercise Period") of one (1) month in accordance with article
6.3 of the Warrant Plans for all vested and unvested Warrants held by any holder of a Warrant (including any independent director).
The Exceptional Exercise Period shall commence from, and be subject to the occurrence of, the Completion Date provided that the
Bidder shall have acquired control of the Target upon Completion of the Bid. To allow the holders of Warrants who decide to exercise
their Warrants during this Exceptional Exercise Period sufficient time to tender their Shares (obtained as a result of the exercise
of such Warrants) in the Bid, the Bidder undertakes to voluntarily reopen its Bid on the same terms and conditions, as during the
First Acceptance Period, for a period of 10 Business Days. The Bidder shall allow the holders of Warrants to tender their Shares
(obtained as a result of the exercise of such Warrants) in the Bid pending the effective issue of these Shares.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7.2 | Treatment of Convertible Bonds
| | --- | ------------------------------



If any holders of the Convertible
Bonds do not tender their Convertible Bonds into the Bid, but instead exercise their put option upon the occurrence of a change
of control as set out in condition 7.5 of the terms and conditions of the Convertible Bonds, the Bidder agrees and undertakes to
provide a secured loan (such loan to be made only once reasonable security documentation has been agreed between the Parties) to
the Target on at arm’s length terms and conditions (or otherwise than as a loan, at the sole discretion of the Bidder), so
that the Target can meet such payment obligations, in full and on a timely basis, as provided for in the terms and conditions of
the Convertible Bonds. The Target shall use such funds exclusively for the payment obligations deriving from the exercise of the
relevant put options as provided for in the terms and conditions of the Convertible Bonds.



| | 7.3 | Incentive Scheme
| | --- | ----------------



| | 7.3.1 | The Bidder acknowledges that, upon closing of the First Acceptance Period with confirmation by
the Bidder that it accepts the Securities tendered in the First Acceptance Period, the Target intends to award a one-off payment
of an incentive bonus with a total cost for the Target (including any taxes and/or employer and employee social security contributions)
of 1% of the Transaction Value (the "Incentive Bonus") to up to six key employees of the Target listed on, and
in accordance with the terms set out in, Schedule 5 (the "Incentive Scheme") to recognize the significant
contribution of such key employees to the Target’s success.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



19





| | 7.3.2 | The Board of Directors intends to hold a board meeting that will ultimately confirm the beneficiaries
among the abovementioned key employees of, and approve the amount payable to each such beneficiaries out of the applicable cap
on, the Incentive Scheme, immediately after the closing of the First Acceptance Period, once the Bidder has announced whether it
will accept the Securities tendered in the First Acceptance Period and prior to the Completion Date. The Target will immediately
inform the Bidder of the decisions taken in respect of the Incentive Scheme. The actual payment of the Incentive Bonus by the Target
will occur as soon as possible thereafter, and in any event prior to the Completion Date.
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7.3.3 | The Bidder acknowledges the intention of the Board of Directors to award such Incentive Bonus to
the abovementioned key employees and confirms that the intended Incentive Bonus has no impact on the launch of the Bid or Completion
of the Bid and is not perceived by the Bidder as a defensive measure nor a material change in the composition of the assets and
liabilities of the Target.

Agreement"). If the Target elects to enforce the abovementioned subscription commitment, the ordinary shares (which may

date of termination of this Agreement (including the signing of the Subscription Agreement);
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | in case the Equity Investment would breach or is reasonably likely to breach applicable anti-trust
regulations; or
| | ---- | ------------------------------------------------------------------------------------------------------------------



23





| | (iii) | in the event that, on a pro forma basis taking into consideration the receipt of the proceeds of
the Equity Investment, (A) the Target is, or is reasonably likely to be, insolvent or declared bankrupt or liquidated or (B) if
proceedings to that effect have been initiated or reasonably threatened by the Target or a third party.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.2.3 | If the subscription commitment described in Clause 9.2.1 is terminated pursuant to Clause 9.2.2(ii),

waived.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.3 | Reverse Break Payment
| | --- | ---------------------



If this Agreement is terminated
by the Target pursuant to Clause 8.2(ii)(b) or (d), the Bidder shall pay to the Target a break payment by way of compensation for

additional financing, business dislocation, reputational harm or adverse market reaction) that may be suffered by the Target equal
to twenty million euro (EUR 20,000,000) (the "Reverse Break Payment").



| | 9.4 | Miscellaneous
| | --- | -------------



| | 9.4.1 | If the Target would be entitled to the Equity Investment (or the Equity Investment Substitute,
as applicable) and the Reverse Break Payment, then the Bidder will only be required to make either the Equity Investment (or the
Equity Investment Substitute, as applicable) or the Reverse Break Payment. Similarly, if the Target would be entitled to the Equity
Investment (or the Equity Investment Substitute, as applicable) or the Reverse Break Payment under several provisions of Clause
9.2 or 9.3 respectively, then the Bidder will only be required to make the Equity Investment (or the Equity Investment Substitute,
as applicable) or the Reverse Break Payment once. The Target shall have the right, in its sole discretion, to elect the provision
pursuant to which it requires the Equity Investment (or the Equity Investment Substitute, as applicable) or the Reverse Break Payment.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



24





| | 9.4.2 | The Parties irrevocably agree, having taken appropriate advice, that the Break Payment, the Equity
Investment (or the Equity Investment Substitute, as applicable) and the Reverse Break Payment constitute fair and reasonable amounts
payable by the Target and the Bidder, as applicable, on the occurrence of the events described above. The right of the Bidder to
receive the Break Payment and the right of the Target to receive the Equity Investment (or the Equity Investment Substitute, as
applicable) or Reverse Break Payment are in addition to any other rights or remedies they may have under Applicable Law. If the
amount of the Break Payment, the Equity Investment (or the Equity Investment Substitute, as applicable) or the Reverse Break Payment
would, at any moment in time, exceed the applicable legal limitations, the Parties will refrain from claiming the nullity, but
the amount due will automatically be reduced to the applicable legal limitations.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.4.3 | The Target shall pay the Break Payment to the Bidder within twenty (20) Business Days of the day
on which the event described in Clause 9.1 occurs. The Bidder shall pay or procure the payment of the Equity Investment Substitute
or the Reverse Break Payment to the Target within twenty (20) Business Days of the day on which the event described in Clause 9.2.1
or Clause 9.3, respectively, occurs. The Parties anticipate, and shall use all reasonable endeavours to secure, that each of the
Break Payment, the Equity Investment Substitute or the Reverse Break Payment, as applicable, is not and will not be treated as
consideration for a taxable supply for VAT purposes. If, however, the Break Payment, the Equity Investment Substitute or the Reverse
Break Payment is determined by any tax authority to be consideration in whole or part for a taxable supply for VAT purposes then:
(a) the Target with respect to the Break Payment and the Bidder with respect to the Equity Investment Substitute or the Reverse
Break Payment, shall provide the other Party with a valid VAT invoice in respect of that supply; and (b) if the Target with respect
to the Break Payment and the Bidder with respect to the Equity Investment Substitute or the Reverse Break Payment, is liable to
account for VAT in respect of that supply, the amount of the Break Payment, the Equity Investment Substitute or the Reverse Break
Payment, as applicable, shall be increased to take account of such recoverable VAT. The Bidder or the Target may assign their creditor
rights under the Break Payment, the Equity Investment Substitute or the Reverse Break Payment, as applicable; provided that if
as a result of such assignment the other Party would become liable to account for VAT in respect of that supply and would not have
been otherwise liable, such Party will not be required to increase the amount of the Break Payment, the Equity Investment Substitute
or the Reverse Break Payment, as applicable, to take account of such recoverable VAT. VAT (if any) will only become due and payable
upon presentation of a valid VAT invoice (or, where there is no provision in the legislation for the jurisdiction concerned that
a VAT invoice is required to be issued, a written demand containing such information as is customary in that jurisdiction).
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.4.4 | Payments pursuant to this Clause 9 shall be made in immediately available funds (without any deduction
or withholding, save only as required by Applicable Law, and without regard to any lien, right of set-off, counterclaim or otherwise)
to such bank account of the Target, the Bidder or their respective Affiliates as may be notified by the recipient in writing for
such purpose. If any amount is required to be withheld from any such payment, the Bidder or the Target, as applicable, shall pay
to the other Party such additional amount so that the amount received by the Bidder or the Target, as applicable, shall be the
same as it would have received without such withholding.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



25





| | 10 | Severability
| | -- | ------------



| | 10.1 | If any provision in this Agreement would be held to be illegal, invalid or unenforceable, in whole
or in part, under Applicable Law, then that provision will be deemed not to form part of this Agreement, and the legality, validity
or enforceability of the remainder of this Agreement will not be affected.
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 10.2 | In such case, each Party will use its reasonable best efforts to negotiate in good faith a valid
replacement provision having a similar economic effect which is as close as possible to that of the invalid, void or unenforceable
provision.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 11 | Costs and expenses
| | -- | ------------------



Without prejudice to the Break Payment,
the Equity Investment (or the Equity Investment Substitute, as applicable) or the Reverse Break Payment or as otherwise provided
in this Agreement, each Party shall pay its own costs and expenses in relation to the negotiation, preparation, execution and carrying
into effect of this Agreement and any matter contemplated by it.

Incentive Scheme



Proposed beneficiaries:



Eduardo Bravo - CEO



Claudia D'Augusta - CFO



María Pascual - VP Regulatory Affairs and Corporate Quality



Wilfried Dalemans - CTO



Marie Paule Richard - CMO



Mary Carmen Diez - VP Medical Affairs and New Product Commercialization



The Incentive Bonus will be a one-off payment
that will be awarded to the proposed beneficiaries for services rendered in the past for the benefit of the Target Group. The Incentive
Bonus is exclusively destined to recognize the significant contribution of the Target's talented, experienced and motivated staff
to the Target Group’s success.



The overall cost for the Target (including
any taxes and/or employer and employee social security contributions) of the Incentive Bonus shall be 1% of the Transaction Value.
However, this cap shall be increased by an amount equal to 1% of the excess transaction value of a higher bid or competing bid
in the event that such higher bid or competing bid takes place. The excess transaction value shall be the difference between the
Transaction Value and the transaction value of the highest bid.



Upon closing of the First Acceptance Period,
the Bidder will announce whether or not the Conditions are satisfied or waived. If the Bidder considers the Conditions satisfied
or decides to waive the Conditions, the Bid will be considered successful (irrespectively of any mandatory or voluntary reopening
of the Bid or the launch of a squeeze-out). Immediately after the closing of the First Acceptance Period, the Board of Directors
of the Target will decide upon the granting of the Incentive Bonus. The decision will not be conditional upon the Bid or change
of control, as the Board will be able to determine at that point whether or not the Bid has been successful.



After the Completion of the Bid, Target's
Board of Directors shall be asked to decide on the definitive amount payable to each of the proposed beneficiaries out of the applicable
cap to the Incentive Bonus. When awarding the Incentive Bonus to the relevant managers, the Board of Directors will not consider
whether or not the relevant managers have tendered their Securities in the Bid. If the Board of Directors decides to approve the
Incentive Scheme, the payment of the Incentive Bonus by the Target will occur as soon as possible, and in any event prior to the
settlement of the Bid by the Bidder (or by the bidder of a competing bid).
