Underwriting Agreement

On May 17, 2018, Celyad SA (the “ Company ”) entered into an Underwriting Agreement (the “ Underwriting Agreement ”) with Wells Fargo Securities, LLC and Bryan, Garnier & Co., as representatives of the several underwriters named therein (the “ Underwriters ”), relating to a global offering (the “ Offering ”) comprised of (i) an offer of 523,913 ordinary shares (the “ Ordinary Shares ”) in the form of American Depositary Shares (the “ ADSs ”), each representing one Ordinary Share, of the Company at a public offering price of $26.28 per ADS in the United States, Canada and certain countries outside of Europe and (ii) an offer of 1,276,087 Ordinary Shares at an offering price of €22.29 per Ordinary Share in Europe and certain countries outside of the United States and Canada in a concurrent private placement. The net proceeds to the Company from the sale of ADSs and Ordinary Shares in the Offering, after deducting the underwriting discounts and commissions and other estimated offering expenses payable by the Company, will be approximately $44.0 million (€37.3 million). The Offering is expected to close on May 22, 2018, subject to the satisfaction of customary closing conditions. The Company has also granted the Underwriters a 30-day option to purchase up to 270,000 additional Ordinary Shares, which may be in the form of ADSs, on the same terms and conditions.

The Offering was made pursuant to the Company’s effective shelf registration statement on Form F-3, as amended (File No. 333-220285) declared effective on October 6, 2017, as supplemented by a prospectus supplement dated May 15, 2018, filed with the U.S. Securities and Exchange Commission (“ SEC ”) on May 16, 2018.

In the Underwriting Agreement, the Company makes customary representations, warranties and covenants and also agrees to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “ Securities Act ”), or to contribute to payments that the Underwriters may be required to make because of such liabilities. The foregoing is only a brief description of the terms of the Underwriting Agreement, does not purport to be a complete description of the rights and obligations of the parties thereunder, and is qualified in its entirety by reference to the Underwriting Agreement that is filed as Exhibit 1.1 to this Form 6-K and incorporated by reference herein. The legal opinion of CMS DeBacker SCRL relating to the Ordinary Shares (including those underlying the ADSs) is filed as Exhibit 5.1 to this Form 6-K and incorporated by reference herein.

On May 15, 2018, the Company issued a press release announcing the Offering, and, on May 17, 2018, the Company issued a press release announcing the pricing of the Offering. Copies of these press releases are filed as Exhibit 99.1 and Exhibit 99.2 to this Form 6-K and incorporated by reference herein.

Results of Operations and Financial Condition

In the prospectus supplement filed with the SEC relating to the Offering, the Company disclosed that it expects that, as of March 31, 2018, the Company estimated that it had cash, cash equivalents and short-term investments of approximately €25.1 million. The Company’s independent registered public accountants have not audited, reviewed or performed any procedures with respect to this financial data and accordingly do not express an opinion or any other form of assurance with respect thereto. This amount could change as a result of further review.

The information contained in this Form 6-K under the heading “Underwriting Agreement” and including the Exhibits is hereby incorporated by reference into the Company’s Registration Statements on Forms F-3 (File No. 333-220285) and S-8 (File No. 333-220737). The information contained in this Form 6-K under the heading “Results of Operations and Financial Condition” is intended to be furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act or the Exchange Act, except as expressly set forth by specific reference in such filing.

All or any part of the Option Shares and/or the Option ADSs to be purchased by the Underwriters hereof are herein called, collectively, the “ Option Securities ”. The Initial Securities and the Option Securities are herein called, collectively, the “ Securities .”


Each ADS will represent one Ordinary Share and the underlying Ordinary Shares for the ADSs issued (the “ Underlying Shares ”) shall be deposited pursuant to a deposit agreement (the “ Deposit Agreement ”), dated June 24, 2015, among the Company, Citibank N.A., as depositary (the “ Depositary ”) and Citibank International Limited as custodian for the Depositary (the “ Custodian ”), pursuant to which the Depositary (or the Custodian acting on behalf of the Depositary) shall deliver the ADSs to the Representatives for the account of the several Underwriters.

The Company understands that the Underwriters propose to make a private placement of the Initial Shares in Europe and countries outside the United States and Canada and a public offering of the Initial ADSs in the United States, in each case as soon as the Representatives deems advisable after this agreement (this “ Agreement ”) has been executed and delivered.

The Company has prepared and filed with the U.S. Securities and Exchange Commission (the “ Commission ”) a registration statement on Form F-3, as amended (File No. 333-220285), covering the public offering and sale of certain securities, including the Securities, under the U.S. Securities Act of 1933, as amended (the “ 1933 Act ”), and the rules and regulations promulgated thereunder (the “ 1933 Act Regulations ”), and has filed such amendments thereto, if any, as may have been required to the date hereof. Such registration statement was declared effective by the Commission under the 1933 Act on October 6, 2017.

Each preliminary prospectus used in connection with the offering of the Securities, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 6 of Form F-3 under the 1933 Act, are collectively referred to herein as a “preliminary prospectus.” Promptly after execution and delivery of this Agreement, the Company will prepare and file a final prospectus relating to the Securities in accordance with the provisions of Rule 424(b) under the 1933 Act Regulations (“ Rule 424(b) ”). The final prospectus, in the form first furnished or made available to the Underwriters for use in connection with the offering of the Securities, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 6 of Form F-3 under the 1933 Act, are collectively referred to herein as the “Prospectus.” The Company has filed with the Commission a registration statement on Form F-6 (File No. 333-204724) covering the registration of the ADSs under the 1933 Act.

SECTION 6.     Indemnification .

(a)     Indemnification of Underwriters . The Company agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) under the 1933 Act (each, an “ Affiliate ”)), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i)    against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included (A) in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) or (B) in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“ Marketing Materials ”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission in any preliminary prospectus, Issuer Free Writing Prospectus, Prospectus or in any Marketing Materials of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii)    against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company;

(iii)    against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.


(b)     Indemnification of Company, Directors and Officers . Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 6(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(c)     Actions against Parties; Notification . Each indemnified party shall give written notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, and such indemnifying party shall assume the defense of such action, including the retention of counsel reasonably satisfactory to such indemnified party and pay all legal or other fees and expenses related to such action or incurred in connection with such indemnified party’s enforcement of this Section, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. The indemnified party or parties shall have the right to retain its or their own counsel in any case, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the retention of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of any such action, (ii) the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, retained counsel to defend such action, or (iii) such indemnified part or parties shall have reasonably concluded that there may be defenses available to it or them that are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such indemnifying party and paid as incurred; provided, however, that in no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)     Settlement without Consent if Failure to Reimburse . If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7.     Contribution . If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such


indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discounts and commissions received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the ADSs underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.


SECTION 8.     Representations, Warranties and Agreements to Survive . All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its Subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors, or any person controlling the Company and (ii) delivery of and payment for the Securities.

SECTION 9.     Termination of Agreement .

(a)     Termination . The Representatives may terminate this Agreement, by notice to the Company at any time at or prior to the Closing Time (i) if there has been, in the judgment of the Representatives, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NASDAQ, or Euronext, or (iv) if trading generally on the NYSE, NASDAQ or Euronext has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, Belgium or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by Federal or New York or Belgian authorities.

(b)     Liabilities . If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 6, 7, 8, 14, 15 and 16 shall survive such termination and remain in full force and effect.

SECTION 10.     Default by One or More of the Underwriters . If one or more of the Underwriters shall fail at the Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “ Defaulted Securities ”), the Representatives shall have the right, within 48 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 48-hour period, then:

(i)    if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii)    if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase, and the Company to sell, the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.


No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Securities, as the case may be, either the (i) Representatives or (ii) the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11.     Notices . All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

SECTION 12.     No Advisory or Fiduciary Relationship . The Company acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering of the Securities and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, any of its subsidiaries or its stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of the Securities or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering of the Securities except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 13.     Parties . This Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.


SECTION 14.     Trial by Jury . The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 15.     GOVERNING LAW . THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.

SECTION 16.     Consent to Jurisdiction; Waiver of Immunity . Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“ Related Proceedings ”) shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “ Specified Courts ”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “ Related Judgment ”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. Each party not located in the United States irrevocably appoints CT Corporation as its agent to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the City and County of New York. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

SECTION 17.     TIME . TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency (the “judgment currency”) other than U.S. dollars, the Company will indemnify each Underwriter against any loss incurred by such Underwriter as a result of any variation as between (a) the rate of exchange at which the U.S. dollar amount is converted into the judgment currency for the purpose of such judgment or order and (b) the rate of exchange at which an Underwriter is able to purchase U.S. dollars with the amount of the judgment currency actually received by such Underwriter. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into U.S. dollars.

SECTION 19.     Counterparts . This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

The Ordinary Shares and the ordinary shares underlying the ADSs will be created through one or more capital increases under Belgian Law (the New Ordinary Shares ).

Nature of the opinion and limitations

This opinion is subject to the following limitations:

 

(a) this opinion is confined to the laws of Belgium, all as they stand as at the date hereof and as such laws are interpreted by the courts of Belgium ( Belgian law ); accordingly, we express no opinion with regard to any other system of law (including the law of jurisdictions other than

(b) in rendering this opinion, we have examined the Registration Statement, the prospectus of the Company included in the Registration Statement (the Prospectus ), as supplemented by the prospectus supplement specifically relating to the offer and sale of the Securities (the Supplement ), the coordinated articles of association of the Company dated 7 February 2018 (the Articles ), and such corporate documents and records of the Company and such other instruments, certificates and documents as we have deemed necessary and appropriate as a basis of the opinion hereinafter expressed (the Documents ) and we have conducted such investigations of Belgian law as we have deemed necessary or advisable for the purpose of giving this opinion letter; as to matters of fact, we have relied on any other document we have deemed relevant and on statements of public officials and directors and officers of the Company;

  interpretation arising, the agreements and documents relating thereto and this present opinion will be determined by the Belgian courts in accordance with Belgian law, and we express no opinion on the interpretation that the Belgian court may make of any such expressions or descriptions; in particular, as far as the term “non-assessable” used in this opinion is concerned, please note that this word has no legal meaning under Belgian law and is used in this opinion only to mean that, with respect to the issuance of New Ordinary Shares, a holder of New Ordinary Shares will have no obligation to pay any additional amount in excess of the subscription price;

 

(i) any person who is entitled to, and does, rely on this opinion agrees, by so relying, that, to the fullest extent permitted by law and regulation (and except in the case of wilful misconduct or fraud) there is no assumption of a personal duty of care by, and such person will not bring any claim against, any individual who is a partner of, member of, associate of, employee of or consultant to CMS DeBacker or any other member of the group of CMS undertakings and that such person will instead confine any claim to CMS DeBacker (which includes the operations conducted in our Brussels office).

(j) this opinion speaks as of the date hereof; no obligation is assumed to update this opinion or to inform any person of any changes of law or other matters coming to our knowledge and occurring after the date hereof, which may affect this opinion in any respect.

Assumptions

(d) that the Documents have been decided upon or entered into for bona fide commercial reasons, within the corporate purpose and corporate interest of the parties thereto and on arms’ length terms by each of the parties, without any fraudulent intent (including as to the interests of creditors);

 

(e) that there has been no mistake of fact ( erreur ), fraud ( dol ), duress ( violence ) or undue influence ( lésion ) in relation to any Document;

(f) that the directors ( administrateurs ) of the Company who have approved and/or executed Documents, have exercised their powers (i) in accordance with the best interest of the Company, (ii) in accordance with their duties under all applicable laws (including the rules regarding conflicts of interest), and (iii) in accordance with the articles of association of the Company and the powers conferred to them.

Opinion

Based upon and subject to the foregoing, and subject as set out below and to any matters not disclosed to us, we are of the opinion (so far as the laws of Belgium as in force on the date of this opinion are concerned) that the New Ordinary Shares will, to the extent that the Company will have received in full all amounts payable by the investors in respect of the New Ordinary Shares, be validly issued, fully paid-up and non-assessable.

Qualifications

Our opinion is subject to the following qualifications:

 

(a) this opinion is subject to bankruptcy, judicial reorganisation, insolvency, attachment, liquidation and other laws of general application relating to or affecting the rights of creditors generally;

 

(b) to the extent that any of the transactions effected under or pursuant to the Documents constitutes a breach or infringement by a party of an agreement or obligations by which it is bound, such breach or infringement may result in a court setting aside the transaction (including the creation of any security interest for the benefit of the third party or parties prejudiced by the breach or infringement if it is established that the parties to the relevant transaction were aware of the breach or infringement). Note however that court decisions do not have the value of binding precedent on other courts;

 

(c) we express no view on any provision stating that the document is the entire agreement or requiring written amendments or waivers insofar as such provision suggests that oral or other modifications, amendments or waivers could not be effectively agreed upon or granted by or between the parties or implied by the course of conduct of the parties;

 

(d) the introduction of legal proceedings in Belgium and enforcement of a judgment would give rise to certain nominal filing charges and notification fees; pursuant to article 851 of the Belgian Judicial Code a foreign plaintiff can be required, at the request of a Belgian defendant, to post a bond to secure payment of any expenses or damages for which the foreign plaintiff might be liable, unless waived in a applicable treaty;

 

(e) court decisions do not have the value of a binding precedent under Belgian law;

 

4 / 5


LOGO

 

(f) the enforcement of a foreign judgment rendered by a court which is not a court of states which are bound by the Council Regulation (or the Recast Council Regulation, as applicable), is subject to the procedures contained in the Belgian Code of Judicial Procedure and can include a re-examination of the merits of the case by the Belgian courts;

 

(g) a suit filed before a Belgian court, including for the purpose of the recognition or enforcement in Belgium of a judgment of any court in the United States of America, is subject to any Belgian rules of civil procedure, including articles 22 to 31 of the International Private Code.

Governing law and jurisdiction

This opinion and any non-contractual obligations arising out of or in relation to this opinion are governed by Belgian law. This opinion is given in accordance with the rules and standards of the Brussels Bar.

The Belgian courts shall have non-exclusive jurisdiction in relation to all disputes (including claims for set-off and counterclaims) arising out of or in connection with this opinion, including, without limitation, disputes arising out of or in connection with (i) the creation, effect or interpretation of, or the legal relationships established by, this opinion, and (ii) any non-contractual obligations arising out of or in connection with this opinion.

We hereby consent to the filing of this opinion as an exhibit to the Supplement, and to the reference to us under the heading “Legal Matters” in the Supplement, without admitting we are “experts” within the meaning of the Securities Act or the rules and regulations of the Commission promulgated thereunder with respect to any part of the Registration Statement.
