, 2021 
 Forbion European Acquisition Corp. 

4001 Kennett Pike, Suite 302 
 Wilmington, Delaware 19807 

Re: Initial Public Offering 
 Ladies and Gentlemen: 

This letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the
“Underwriting Agreement”) entered into by and between Forbion European Acquisition Corp., a Cayman Islands exempted company (the “Company”), and UBS Securities LLC and Kempen & Co. USA, Inc.,
as underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of up to 11,500,000 of the Company’s units
(including up to 1,500,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one of the Company’s Class A ordinary shares, par value $0.0001 per share (the
“Class A Ordinary Shares”), and one-third of one redeemable warrant. Each whole warrant (each, a “Warrant”) entitles the holder
thereof to purchase one Class A Ordinary Share at a price of $11.50 per share, subject to adjustment as described in the Prospectus (as defined below). The Units will be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) and the Company has applied to have the
Units listed on the Nasdaq Global Market. Certain capitalized terms used herein are defined in paragraph 14 hereof. 
 In order to induce the Company and
the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each of Forbion Growth Sponsor FEAC I
B.V., a Dutch private limited liability company (the “Sponsor”) and the undersigned individuals, each of whom is, or will be, a member of the Company’s board of directors and/or management team or an employee of the
Company (each of the undersigned individuals, an “Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows: 

 

	 	1.	 It is acknowledged and agreed that the Company shall not enter into a definitive agreement regarding a proposed
Business Combination without the prior written consent of the Sponsor. 

  

	 	2.	 The Sponsor and each Insider agrees with the Company that if the Company seeks shareholder approval of a
proposed Business Combination, then in connection with such proposed Business Combination, it, he or she shall (i) vote any Ordinary Shares (as defined below) owned by it, him or her in favor of any proposed Business Combination and
(ii) not redeem any Ordinary Shares owned by it, him or her in connection with such shareholder approval. If the Company seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor and each Insider agrees that
it, he or she will not sell or tender any Ordinary Shares owned by it, him or her in connection therewith. 

  

	 	3.	 The Sponsor and each Insider hereby agrees with the Company that in the event that the Company fails to
consummate a Business Combination within 18 months from the closing of the Public Offering (or up to 24 months from the closing of this offering if we extend the period of time to consummate a Business Combination), or such later period approved by
the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association (as it may be amended from time to time, the “Charter”), the Sponsor and each Insider shall
take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten (10) business days thereafter, redeem 100% of the
Class A Ordinary Shares sold as part of the Units in the Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount
then on deposit in the Trust Account (as defined below), including interest earned on the funds held in the Trust Account (less taxes payable and up to $100,000 of interest to pay dissolution expenses),

	 	
divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public Shareholders’ (as defined below) rights as shareholders (including the right
to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors,
dissolve and liquidate, subject, in each case, to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. The Sponsor and each Insider agrees to
not propose any amendment to the Charter (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with its initial business combination or to redeem 100% of the Offering Shares if the Company does
not complete a Business Combination within the required time period set forth in the Charter or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial
Business Combination activity, unless the Company provides its Public Shareholders with the opportunity to redeem their Offering Shares upon approval of any such amendment at a per-share price, payable in
cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest to pay
dissolution expenses), divided by the number of then outstanding Offering Shares. 

 The Sponsor and each Insider acknowledges
that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares held by it, him or
her. The Sponsor and each Insider hereby further waives, with respect to any Ordinary Shares held by it, him or her, if any, any redemption rights it, he or she may have in connection with (a) the consummation of a Business Combination,
including, without limitation, any such rights available in the context of a shareholder vote to approve such Business Combination, or (b) a shareholder vote to approve an amendment to the Charter (A) to modify the substance or timing of
the Company’s obligation to allow redemption in connection with its initial business combination or to redeem 100% of the Offering Shares if the Company has not consummated a Business Combination within the time period set forth in the Charter
or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity or in the context of a tender offer made by the Company to purchase
Offering Shares (although the Sponsor and the Insiders shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold if the Company fails to consummate a Business Combination within the time period set
forth in the Charter). The undersigned acknowledges and agrees that there will be no distribution from the Trust Account with respect to any warrants, all rights of which will terminate on the Company’s liquidation. 

 

	 	4.	 The undersigned acknowledges and agrees that prior to entering into a definitive agreement for a Business
Combination with a target business that is affiliated with the undersigned or any other Insiders of the Company or their affiliates, such transaction must be approved by a majority of the Company’s disinterested independent directors and the
Company must obtain an opinion from an independent investment banking firm that is a member of the Financial Industry Regulatory Authority, Inc. or an independent valuation or appraisal firm that such Business Combination is fair to the Company from
a financial point of view. 

  

	 	5.	 During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such
date, the Sponsor and each Insider shall not, without the prior written consent of the Underwriters, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to
dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), and the rules and regulations of the Commission promulgated thereunder, with respect to, any Units, Ordinary Shares (including, but not limited to, Founder Shares), Warrants or any securities convertible
into, or exercisable, or exchangeable for, Ordinary Shares (but excluding Units and Ordinary Shares purchased in the Public Offering or thereafter) owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of any Units, Ordinary Shares (including, but not limited to, Founder Shares), Warrants or 

  
 2 

	 	
any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by it, him or her, whether any such transaction is to be settled by delivery of such securities, in
cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii). The provisions of this paragraph will not apply if the release or waiver is effected solely to permit a transfer not for
consideration and the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer. 

 

	 	6.	 In the event of the liquidation of the Trust Account upon the failure of the Company to consummate its initial
Business Combination within the time period set forth in the Charter, the Sponsor (the “Indemnitor”), which for purposes of clarification shall not extend to any other shareholders, members or managers of the Sponsor, or any
of the other undersigned, agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in
investigating, preparing or defending against any litigation, whether pending or threatened) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company or
(ii) any prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or Business Combination agreement (a “Target”); provided,
however, that such indemnification of the Company by the Indemnitor (x) shall apply only to the extent necessary to ensure that such claims by a third party or a Target do not reduce the amount of funds in the Trust Account to below the
lesser of (i) $10.25 per Offering Share and (ii) the actual amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.25 per Offering Share is then held in the Trust Account due
to reductions in the value of the trust assets, in each case, less taxes payable, (y) shall not apply to any claims by a third party or a Target which executed a waiver of any and all rights to the monies held in the Trust Account (whether or
not such waiver is enforceable) and (z) shall not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event that any
such executed waiver is deemed to be unenforceable against such third party, the Indemnitor shall not be responsible to the extent of any liability for such third party claims. The Indemnitor shall have the right to defend against any such claim
with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense.

  

	 	7.	 To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional
1,500,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number of Founder Shares equal to 375,000 multiplied by a fraction, (i) the numerator of
which is 1,500,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 1,500,000. The forfeiture will be adjusted to the extent that the over-allotment
option is not exercised in full by the Underwriters so that the Founder Shares will represent an aggregate of 20% of the Company’s issued and outstanding Ordinary Shares after the Public Offering (not including Class A Ordinary Shares
underlying the Warrants or Private Placement Warrants (as defined below)). The Initial Shareholders further agree that to the extent that the size of the Public Offering is increased or decreased, the Company will purchase or sell Units or effect a
share repurchase or share capitalization, as applicable, immediately prior to the consummation of the Public Offering in such amount as to maintain the number of Founder Shares at 20% of the issued and outstanding Ordinary Shares upon the
consummation of the Public Offering. In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 1,500,000 in the numerator and denominator of the formula in the first sentence of this paragraph
shall be changed to a number equal to 15% of the number of Class A Ordinary Shares included in the Units issued in the Public Offering and (B) the reference to 375,000 in the formula set forth in the first sentence of this paragraph shall
be adjusted to such number of Founder Shares that the Sponsor would have to surrender to the Company in order for the number of Founder Shares to be equal to an aggregate of 20% of the Company’s issued and outstanding Ordinary Shares after the
Public Offering (not including Class A Ordinary Shares underlying the Warrants or Private Placement Warrants). 

  
 3 

	 	8.	 The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company
would be irreparably injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 2, 3, 5, 6, 7, 9(a), 9(b) and 12, as applicable, of this Letter Agreement, (ii) monetary damages may not be an
adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such
breach. 

  

	 	9.	 (a) The Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or any
Class A Ordinary Shares issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination and (B) subsequent to the Business Combination, (x) if the
closing price of the Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination or (y) the date on which the Company completes a liquidation, merger, share exchange or other similar
transaction that results in all of the Company’s shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property (the “Founder Shares
Lock-up Period”). 

 (b) The Sponsor and each Insider agrees that it,
he or she shall not Transfer any Private Placement Warrants, Working Capital Warrants or Extension Loan Warrants (or any Class A Ordinary Shares underlying the Private Placement Warrants), until 30 days after the completion of a Business
Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”). 
 (c) Notwithstanding the provisions set forth in paragraphs
9(a) and (b), Transfers of the Founder Shares, Private Placement Warrants, Working Capital Warrants, Extension Loan Warrants and the Class A Ordinary Shares underlying the Private Placement Warrants or the Founder Shares and that are held by
the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 9(c)), are permitted (a) to the Company’s officers or directors, any affiliate or family member of any of the Company’s officers or
directors, any affiliate of the Sponsor or to any members of the Sponsor or any affiliates of such members, or any employees of such affiliates; (b) in the case of an individual, by gift to a member of such individual’s immediate family or
to a trust, the beneficiary of which is a member of such individual’s immediate family, an affiliate of such individual or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon
death of such individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection
with the consummation of an initial Business Combination at prices no greater than the price at which the securities were originally purchased; (f) by virtue of the laws of the Cayman Islands or the Sponsor’s articles of association upon
dissolution of the Sponsor; (g) in the event of the Company’s liquidation prior to the completion of an initial Business Combination; or (h) in the event of the Company’s liquidation, merger, share exchange or other similar
transaction which results in all of the Company’s shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property subsequent to the Company’s completion of an initial Business
Combination; provided, however, that in the case of clauses (a) through (f), these permitted transferees must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions herein and the other
restrictions contained in this Agreement (including provisions relating to voting, the Trust Account and liquidating distributions). 
  

	 	10.	 Each of the Insiders who is or is nominated to be a director or officer of the Company agrees to serve in such
capacity until the earlier of the consummation by the Company of an initial Business Combination, the liquidation of the Company, or his or her removal, death or incapacity. The Sponsor and each Insider represents and warrants that it, he or she has
never been suspended or 

  
 4 

	 	
expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. For each Insider who is
or is nominated to be a director or officer of the Company, such Insider’s biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all material respects and does not
omit any material information with respect to the Insider’s background. For each Insider who is or is nominated to be a director or officer of the Company, such Insider’s questionnaire furnished to the Company is true and accurate in all
respects. The Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a respondent in any legal action for, any injunction,
cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; it, he or she
has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and it, he or
she is not currently a defendant in any such criminal proceeding. 

  

	 	11.	 The Company agrees that, except as disclosed in the Prospectus, neither the Sponsor nor any Insider or
employee, nor any affiliate of the Sponsor or any Insider or employee of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, non-cash payments, monies in respect
of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate, the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is),
other than the following, none of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business Combination: repayment of a loan and advances up to an aggregate of $500,000 made to the Company by the
Sponsor; payment to the Sponsor for certain office space, administrative and support services provided to the Company by an affiliate of the Sponsor for a total up to $10,000 per month; reimbursement for any reasonable
out-of-pocket expenses related to identifying, investigating, negotiating and completing an initial Business Combination; and repayment of loans, if any, and on such
terms as to be determined by the Company from time to time, made by the Sponsor or an affiliate of the Sponsor or any of the Company’s officers or directors to finance transaction costs in connection with an intended initial Business
Combination, provided, that, if the Company does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used by the Company to repay such loaned amounts so long as no proceeds from the
Trust Account are used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.50 per warrant at the option of the lender. Such warrants would be identical to the Private Placement Warrants, including as
to exercise price, exercisability and exercise period. 

  

	 	12.	 The Company, the Sponsor and each Insider has full right and power, without violating any agreement to which
it, he or she is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter
Agreement and, as applicable, to serve as an officer and/or director on the board of directors of the Company and hereby consents to being named in the Prospectus as an officer and/or director of the Company.
