the shareholders of FLAC is sought, all of such Class B Holder’s FLAC Shares, and in each such case cause all the FLAC Shares held by such Class B Holder to be counted as present thereat for purposes of calculating a quorum, and vote
or provide his, her or its consent: (a) in favor of the Business Combination Agreement and the Transactions, including in favor of each Transaction Proposal, (b) in favor of any other matter reasonably necessary or required to the

Holdco Share on the Effective Date upon consummation of the Merger. 
 (b) Redemption Rights. Each Class B Holder hereby waives
any and all rights to redeem any FLAC Shares (in connection with the Transactions or otherwise) as set forth in the Governing Documents of FLAC, and shall not elect to cause FLAC to redeem any FLAC Shares beneficially owned or owned of record by the

participate in the filing of) a registration statement with the SEC (other than the Registration Statement/Proxy Statement), deposit into a voting trust, grant any proxy or power of attorney with respect to, or establish or increase a put equivalent
position or liquidate or decrease a call equivalent position (within the meaning of Section 16 of the Exchange Act) with respect to, any FLAC Shares or FLAC Warrants held by such Class B Holder, (ii) enter into any swap or other
arrangement that transfers to another Person, in whole or in part, any of the economic consequences of ownership of any shares of FLAC Shares or FLAC Warrants held by such Class B Holder (clauses (i) and (ii) collectively, a
“Transfer”) or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii); provided, however, that the foregoing shall not prohibit Transfers from a Class B Holder to

Annex A. 

  
 2

exchange of FLAC Shares or FLAC Warrants of, on or affecting the FLAC Shares or FLAC Warrants owned by the Class B Holders or otherwise, (b) any Class B Holder purchases or otherwise acquires beneficial ownership of any FLAC Shares,
FLAC Warrants or other Equity Securities of FLAC after the date of this Agreement, or (c) any Class B Holder acquires the right to vote or share in the voting of any FLAC Shares or other Equity Securities of FLAC after the date of this

Class B Holder shall notify FLAC, Holdco and the Company in writing and as promptly as practicable of any such New Securities and (y) such New Securities shall be subject to the terms of this Agreement to the same extent as if they
constituted the FLAC Shares or FLAC Warrants owned by the Class B Holders as of the date hereof.

EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, IN EACH CASE, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER
IN CONTRACT, TORT, EQUITY, OR OTHERWISE. THE PARTIES EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES MAY FILE AN ORIGINAL COUNTERPART OF A
COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY

parties hereto and their respective heirs, successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations hereunder will be assigned (including by operation of law) without the prior written consent of all
of the other parties hereto. 
 Section 3.5 Specific Performance. The parties hereto agree that irreparable damage may occur in
the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions to

entitled at law or in equity, and in each case, without posting a bond or undertaking and without proof of damages. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief
when expressly available pursuant to the terms of this Agreement on the basis that the other parties have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. 

Section 3.6 Amendment. This Agreement may not be amended, changed, supplemented, waived or otherwise modified or terminated,
except upon the execution and delivery of a written agreement executed by FLAC, Holdco, the Company and the Class B Holders. Notwithstanding anything to the contrary contained herein, any holder of Class B Shares may become party to this

 (a) Organization; Due Authorization. The Investor has the full power and authority to execute and deliver this
Agreement and to perform the Investor’s obligations hereunder. If the Investor is an entity, it is duly organized, validly existing and in good standing under the Laws of the jurisdiction in which it is incorporated, formed, organized or
constituted, and the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby are within such Investor’s corporate, limited liability company or organizational powers and have been duly
authorized by all necessary corporate, limited liability company or organizational actions on the part of such Investor. This Agreement has been duly executed and delivered by the Investor and, assuming due authorization, execution and delivery by

Enforceability Exceptions). If this Agreement is being executed in a representative or fiduciary capacity, the Person signing this Agreement has full power and authority to enter into this Agreement on behalf of the Investor. 

(b) Ownership. The Investor is the record and beneficial owner (as defined in the Exchange Act) of, and has good title to the FLAC
Shares and FLAC Warrants set forth on the signature page hereto, and there exist no Liens or any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such FLAC Shares or FLAC Warrants (other
than transfer restrictions under the Securities Act)) affecting any such FLAC Shares or FLAC Warrants, other than Liens pursuant to (i) this Agreement, (ii) FLAC’s Governing Documents, (iii) the Business Combination Agreement, or
(iv) any applicable securities Laws. The FLAC Shares and FLAC Warrants set forth on the signature page hereto are the only Equity Securities in FLAC owned of record or beneficially by the Investor on the date of this Agreement, and none of the
Investor’s FLAC Shares or FLAC Warrants are subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of such FLAC Shares or FLAC Warrants, except as provided hereunder. Other than the FLAC Warrants, the
Investor does not hold or own any rights to acquire (directly or indirectly) any Equity Securities of FLAC or any securities convertible into, or which can be exchanged for, Equity Securities of FLAC. 

  
 3 

 (c) No Conflicts. The execution and delivery of this Agreement by the Investor does
not, and the performance by the Investor of its obligations hereunder will not, (i) conflict with or result in a violation of the organizational documents of the Investor or (ii) require any consent or approval that has not been given or
other action that has not been taken by any Person (including under any Contract binding upon the Investor or the Investor’s FLAC Shares or FLAC Warrants), in each case, to the extent such consent, approval or other action would prevent, enjoin
or materially delay the performance by the Investor of its, his or her obligations under this Agreement, the Business Combination Agreement or the transactions contemplated hereby or thereby. 

(d) Litigation. There are no Proceedings pending against the Investor, or, to the knowledge of the Investor, threatened against the
Investor, before (or, in the case of threatened Proceedings, that would be before) any arbitrator or any Governmental Entity, which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by the Investor of its, his
or her obligations under this Agreement, the Business Combination Agreement or the transactions contemplated hereby or thereby. 
 (e) No
Brokers. No investment banker, broker, finder, consultant or intermediary or other Person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission based upon arrangements made by or on behalf

that each of FLAC, Holdco and the Company is entering into the Business Combination Agreement in reliance upon the Investor’s execution and delivery of this Agreement.

disclaims any such other representations or warranties.

the Company. Upon such termination of this Agreement, all obligations of the parties under this Agreement will terminate, without any liability or other obligation on the part of any party hereto to any Person in respect hereof or the transactions
contemplated hereby, and no party hereto shall have any claim against another (and no Person shall have any rights against such party), whether under contract, tort or otherwise, with respect to the subject matter hereof; provided,
however, that the termination of this Agreement shall not relieve any party hereto from liability arising in respect of any breach of this Agreement prior to such termination. This Article III shall survive the termination of
this Agreement.

 Section 3.2 Governing Law; Venue. This Agreement shall be governed by and
construed in accordance with the Laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the law
of any jurisdiction other than the State of Delaware. Each of the parties irrevocably and unconditionally submits to the exclusive jurisdiction of the Chancery Court of the State of Delaware (or, if the Chancery Court of the State of Delaware
declines to accept jurisdiction, any state or federal court within the State of Delaware or, in the event each federal court within the State of Delaware declines to accept jurisdiction, any other Delaware state court), for the purposes of any
Proceeding (a) arising under this Agreement or (b) in any way connected with or related or incidental to the dealings of the parties in respect of this Agreement, and irrevocably and unconditionally waives any objection to the laying of
venue of any such Proceeding in any such court, and further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such Proceeding has been brought in an inconvenient forum. Each party irrevocably and
unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any Proceeding against such party (i) arising under this Agreement or (ii) in any way connected with or related or incidental
to the dealings of the parties in respect of this Agreement, (A) any claim that it is not personally subject to the jurisdiction of the courts as described in this Section 3.2 for any reason, (B) that it or its
property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of
judgment or otherwise) and (C) that (1) the Proceeding in any such court is brought against such party in an inconvenient forum, (2) the venue of such Proceeding against such party is improper or (3) this Agreement, or the
subject matter hereof, may not be enforced against such party in or by such courts. Each Party agrees that service of any process, summons, notice or document by registered mail to such party’s respective address set forth in
Section 3.8 below shall be effective service of process for any such Proceeding. 
 Section 3.3 Waiver of
Jury Trial. THE PARTIES EACH HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, IN EACH
CASE, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. THE PARTIES EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY
AND THAT THE PARTIES MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT
(A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH SUCH PARTY UNDERSTANDS AND HAS
CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (D) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION 3.3.

 Section 3.4 Assignment. This Agreement and all of the provisions hereof will be
binding upon and inure to the benefit of the parties hereto and their respective heirs, successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations hereunder will be assigned (including by operation of
law) without the prior written consent of all of the other parties hereto. 
 Section 3.5 Specific Performance. The parties
hereto agree that irreparable damage may occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto shall be
entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Chancery Court of the State of Delaware (or, if the Chancery Court of the State of Delaware
declines to accept jurisdiction, any state or federal court within the State of Delaware or, in the event each federal court within the State of Delaware declines to accept jurisdiction, any other Delaware state court), this being in addition to any
other remedy to which such party is entitled at law or in equity, and in each case, without posting a bond or undertaking and without proof of damages. Each of the parties agrees that it will not oppose the granting of an injunction, specific
performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other parties have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any
reason at law or equity. 
 Section 3.6 Amendment. This Agreement may not be amended, changed, supplemented, waived or otherwise
modified or terminated, except upon the execution and delivery of a written agreement executed by FLAC and the Investor. Notwithstanding anything to the contrary contained herein, any holder of FLAC Shares or FLAC Warrants may become party to this
Agreement by executing and delivering a joinder to this Agreement in the form attached hereto as Annex A. In such event, each such Person shall thereafter shall be deemed an Investor for all purposes under this Agreement. 

Section 3.7 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent
jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or
unenforceable.
