Ladies and Gentlemen:

BioNTech SE, a European stock corporation (Societas Europaea) incorporated in Germany and governed by the laws of the European Union and the Federal Republic of Germany and registered with the commercial register (Handelsregister) of the local court (Amtsgericht) of Mainz, Federal Republic of Germany, under number HRB 48720 (the “Company”), proposes to issue and sell to the several underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), an aggregate of [●] new ordinary registered shares (Namensaktien) of the Company with no par value and a notional amount attributable to each share of €1.00 (any such share an “Ordinary Share”) (the “Underwritten Shares”) in the form of American Depositary Shares (the “Underwritten ADSs”). Certain shareholders of the Company named in Schedule 2 hereto (the “Selling Stockholders”) propose to sell to the Underwriters, at the option of the Underwriters, up to an aggregate of [●] existing American Depositary Shares (the “Option ADSs”). The Underwritten Shares and the ordinary shares represented by the Option ADSs are herein referred to as the “Shares”. The Underwritten ADSs and the Option ADSs (to the extent that the aforementioned option is exercised) are hereinafter collectively referred to as the “Offered ADSs”. Any one ordinary registered share of the Company is referred to herein as a “Share”, the Shares to be outstanding after giving effect to the sale of the Shares are referred to herein as the “Stock” and an American Depositary Share as an “ADS.”

The Underwritten ADSs are to be issued, and the Option ADSs have been issued, pursuant to a deposit agreement (the “Deposit Agreement”), dated October 9, 2019, among the Company and The Bank of New York Mellon as depositary (the “Depositary”). Each Offered ADS will initially represent the right to receive one Ordinary Share deposited with the Depositary pursuant to the Deposit Agreement.

The Company and the Selling Stockholders hereby confirm their agreement with the several Underwriters concerning the purchase and sale of the Shares in the form of Offered ADSs, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form F-1 (File No. 333-[●]), including a prospectus, relating to the Shares and the Offered ADSs. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before effectiveness, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with a confirmation of sales of the Shares in the form of Offered ADSs. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Any reference in this underwriting agreement (this “Agreement”) to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 5 of Form F-1 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively with the pricing information set forth on Annex A hereto, the “Pricing Disclosure Package”): a Preliminary Prospectus dated [●], 2020 and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act), if any, listed on Annex A hereto.

“Applicable Time” means [●] P.M., New York City time, on [●], 2020.

2. Purchase of the Underwritten ADS.

(a) Each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to:

(i) purchase from the Company the respective number of Underwritten ADSs set forth opposite such Underwriter’s name in Schedule 1 hereto,

(ii) cause BofA Securities, Inc. (the “Settlement Agent”), acting for the account of the several Underwriters, to make available to Joh. Xxxxxxxxx, Xxxxxxx & Co. KG (the “German Subscription Agent”), on [●], 2020, an amount equal to an issue price of €1.00 (the “Issue Price”) per Underwritten Share (i.e. the Issue Price multiplied by the number of the Underwritten Shares, with such product being the “Aggregate Issue Price”),

(iii) cause the German Subscription Agent, acting in its own name but for the account of the several Underwriters, (x) to subscribe, on [●], 2020, for the Underwritten Shares at the Aggregate Issue Price by way of executing and delivering to the Company a subscription certificate (Zeichnungsschein) (the “Subscription

Certificate”) for the Underwritten Shares in the form attached as Exhibit A hereto, duly signed in duplicate form pursuant to Section 185 of the German Stock Corporation Act (Aktiengesetz or “AktG”), such Subscription Certificate, in accordance with its terms, to expire at 11:30 a.m. Frankfurt am Main time on [●], 2020, (y) to pay the Aggregate Issue Price to the Company by crediting, with value date as of [●], 2020 the Aggregate Issue Price into a special account opened at the German Subscription Agent [(IBAN: XX00000000000000000000; BIC: XXXXXXXXXXX)] and entitled “Sonderkonto Kapitalerhöhung Juli 2020” (the “Capital Increase Account”), such account to be noninterest bearing and free of charges (including negative interest), and (z) upon credit of the Aggregate Issue Price to the Capital Increase Account, to deliver to the Company a bank certificate (Einzahlungsbestätigung) in the form attached as Exhibit B hereto (the “Bank Certificate”) confirming such credit (Sections 188(2), 36(2), 36a(1) and 37(1) AktG).

(b) Promptly upon receipt of the Subscription Certificate and Bank Certificate pursuant to paragraph (a)(iii) above, the Company shall use its best efforts to effect the registration of the capital increase in the commercial register. Copies of all documents filed with the commercial register shall be delivered to the German Subscription Agent. Promptly upon the registration of the capital increase in the commercial register, but at the latest by 12:00 (noon) Frankfurt am Main time on [●], 2020, the Company shall, by telefax or pdf-document attached to an email, with two original certified copies to follow promptly by courier, furnish the German Subscription Agent with a certified copy of the registration notice of the commercial register, a certified chronological excerpt from the commercial register and a certified copy of the articles of association of the Company, each evidencing such capital increase. If the registration with the commercial register of the increase of the Company’s registered share capital in an amount of €[●] has not been effected by 11:30 a.m. Frankfurt am Main time on [●], 2020, the Subscription Certificate for the Underwritten Shares shall expire and the Settlement Agent, on behalf of the several Underwriters, may obtain repayment of the Issue Price for the Underwritten Shares by way of instructing the German Subscription Agent to cancel the credit of the Aggregate Issue Price for the Underwritten Shares to the Capital Increase Account and to transfer the Aggregate Issue Price to the Settlement Agent for the account of the several Underwriters. In such event, the Representatives, on behalf of the several Underwriters, may cause the German Subscription Agent to submit to the Company a new Subscription Certificate for the Underwritten Shares (to expire in accordance with its terms on a date to be determined by the Representatives on behalf of the several Underwriters) and the Company shall use its best efforts to effect the registration of the capital increase in the commercial register. If the Representatives, on behalf of the several Underwriters, have not caused a submission of a new Subscription Certificate for the Underwritten Shares to the Company on or prior to [●], 2020, all obligations of the Underwriters to purchase, subscribe for and pay for the Underwritten Shares shall terminate. In this event, the reimbursement obligations of the Company pursuant to Section 15 and the provisions set out in Sections 11 and 13 of this Agreement shall remain in full force and effect.

(c) Each Underwriter, agrees, severally and not jointly, to cause the German Subscription Agent, acting in its own name, but for the account of the several Underwriters, to transfer title to the Underwritten Shares to the Depositary on the Closing Date (as defined below), to enable the delivery by the Depositary of the Underwritten ADSs in respect of the Underwritten Shares to the Settlement Agent for the account of the several Underwriters, for subsequent delivery to the other several Underwriters or to investors, as the case may be, by way of book-entry.

(d) On [●], 2020, the Company shall deliver to the German Subscription Agent one global share certificate in the form set forth as Exhibit C hereto representing the Underwritten Shares and each Underwriter, agrees, severally and not jointly, to cause the German Subscription Agent, acting in its own name, but for the account of the several Underwriters, to deliver such global share certificate to Clearstream Banking AG, Frankfurt am Main (“Clearstream”), and procure the Underwritten Shares to be credited to such securities account with a participant of Clearstream as the Depositary may designate (the “Custodian”).

3. Option to Purchase Additional ADSs.

(a) Each of the Selling Stockholders agrees, severally and not jointly, as and to the extent indicated in Schedule 2 hereto, to sell, the Option ADSs to the several Underwriters as provided in this Agreement, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from each Selling Stockholder the Option ADSs at $[●] per Option ADS, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Underwritten ADSs but not payable on the Option ADSs (the “Option ADS Purchase Price”). If the Underwriters exercise the option to purchase Option ADSs in part, the number of Option ADSs to be sold by each Selling Stockholder shall be the number of Option ADSs which bears the same ratio to the aggregate number of Option ADSs being purchased as the number of Option ADSs set forth opposite the name of such Selling Stockholder in Schedule 2 hereto bears to the aggregate number of Option ADSs that could be purchased from the Selling Stockholders by the several Underwriters upon exercise of the option to purchase Option ADSs in whole under this Agreement. In the event of fractional Option ADSs to be sold, each of the Selling Stockholders will round down to the nearest whole Option ADS and the largest Selling Stockholder will add the number of Option ADSs to its share necessary to ensure the total number of Option ADSs being purchased by the Underwriters is equal to the total number of Option ADSs being sold by the Selling Stockholders.

(b) If any Option ADSs are to be purchased, the number of Option ADSs to be purchased by each Underwriter shall be the number of Option ADSs which bears the same ratio to the aggregate number of Option ADSs being purchased as the number of Underwritten ADSs set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 14 hereof) bears to the aggregate number of Underwritten ADSs being purchased from the Company by the several Underwriters. In the event of fractional Option ADSs to be purchased, each of the Underwriters will round down to the nearest whole Option ADS and X.X. Xxxxxx Securities LLC will add the number of Option ADSs to its share necessary to obtain the total aggregate number of Option ADSs being purchased by the Underwriters.

(c) The Underwriters may exercise the option to purchase Option ADSs in whole or from time to time, in part, on or before the thirtieth day following the date of the Prospectus, by written notice (the “Option Exercise Notice”) from the Representatives to the Attorneys-in-Fact (as defined below), with a copy to the Company. Such notice shall set forth the aggregate number of Option ADSs as to which the option is being exercised and the date and the time when the Option ADSs are to be delivered and paid for, which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date nor later than the tenth full business day after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 14 hereof). Any such notice shall be given at least two full business days prior to the Additional Closing Date (as defined below).

4. Sale of ADSs to the Public; Delivery and Payment.

(a) The Company and the Selling Stockholders understand that the several Underwriters intend to make a public offering of the Offered ADSs, and initially to offer the Offered ADSs on the terms set forth in the Pricing Disclosure Package. The Company and the Selling Stockholders acknowledge and agree that the several Underwriters may offer and sell Offered ADSs to or through any affiliate of an Underwriter.

(b) Payment for the Underwritten ADSs shall be made, subject to the conditions set forth herein, by wire transfer in immediately available funds in U.S. dollar and with respect to the Aggregate Issue Price in euro to the accounts specified by the Company to the Representatives at the offices of Xxxxx Xxxx & Xxxxxxxx LLP, New York, New York no later than 10:00 a.m. New York City time on [●], 2020, or at such other time or place on the same or such other date, not later than the fifth business day thereafter. Payment for the Option ADSs shall be made, subject to the conditions set forth herein, by wire transfer in immediately available funds in U.S. dollar to the accounts specified by the Attorneys-in-Fact to the Representatives on the date and at the time and place specified by the Option Exercise Notice. The time and date of such payment for the Underwritten ADSs is referred to herein as the “Closing Date,” and the time and date for such payment for the Option ADSs, if other than the Closing Date, is herein referred to as the “Additional Closing Date”.

(c) Payment for the ADSs to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made subject to the conditions set forth herein, against delivery of the ADSs to the Settlement Agent for the account of the several Underwriters of the Offered ADSs to be purchased on such date with any transfer taxes payable in connection with the sale of such ADSs (including any transfer taxes payable with respect to the underlying Ordinary Shares) duly paid by the Company. The Company shall procure (and in the form of the Deposit Agreement has made the necessary arrangements) that the Depositary delivers the Underwritten ADSs through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct. The aggregate U.S. dollar amount to be paid by the several Underwriters to the Company on the Closing Date shall be $[●] per ADS (the “Purchase Price”) multiplied by the number of Underwritten ADSs delivered on such date, less the Aggregate Issue Price converted from euro into U.S. dollar (the “Excess Proceeds Amount”). Solely for the purpose of calculating the Excess Proceeds Amount, the Aggregate Issue Price shall convert from euro into U.S. dollars by applying the exchange rate, which the Settlement Agent can reasonably obtain at the time it converts U.S. dollars into a euro amount for purposes of making the payment of the Aggregate Issue Price to the German Subscription Agent. The Settlement Agent, on behalf of the several Underwriters, shall cause payment of the Excess Proceeds Amounts in U.S. dollars and shall instruct the German Subscription Agent via email to transfer the Aggregate Issue Price in euro to the accounts designated by the Company on the Closing Date. The Selling Stockholders shall deliver the Option ADSs through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct. The aggregate U.S. dollar amount to be paid by the several Underwriters to the respective Selling Stockholder on the applicable Additional Closing Date shall be the Option ADS Purchase Price multiplied by the number of Option ADSs delivered by the respective Selling Stockholder on such date.

(d) Each of the Company and each Selling Stockholder acknowledge and agree that each of the Representatives and the other Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Selling Stockholders with respect to the offering of the Offered ADSs contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Selling Stockholders or any other person. Additionally, neither the Representatives nor any other Underwriter is advising the Company, the Selling Stockholders or

any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company and the Selling Stockholders shall consult with their own advisors concerning such matters and each shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representatives nor any other Underwriters shall have any responsibility or liability to the Company or the Selling Stockholders with respect thereto. Any review by the Representatives and the other Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the several Underwriters and shall not be on behalf of the Company or the Selling Stockholders. Moreover, each Selling Stockholder acknowledges and agrees that, although the Representatives may be required or choose to provide certain Selling Stockholders with certain Regulation Best Interest and Form CRS disclosures in connection with the offering, the Representatives and the other Underwriters are not making a recommendation to any Selling Stockholder to participate in the offering, enter into a “lock-up” agreement, or sell any Shares at the price determined in the offering, and nothing set forth in such disclosures is intended to suggest that the Representatives or any Underwriter is making such a recommendation.

(b) Indemnification of the Underwriters by the Selling Stockholders. Each of the Selling Stockholders severally in proportion to the number of Shares to be sold by such Selling Stockholder hereunder agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication or the Pricing Disclosure Package, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in paragraph (c) below; provided, however, that (i) each Selling Stockholder’s agreement to indemnify and hold harmless hereunder shall only apply

insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Selling Stockholder furnished to the Company in writing by such Selling Stockholder expressly for use in the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or any Pricing Disclosure Package, it being understood and agreed upon that the only such information furnished by any Selling Stockholder consists of the following information in the Prospectus furnished on behalf of such Selling Stockholder: the name and address of the Selling Stockholder, the number of ADSs held by the Selling Stockholder and the number of Option ADSs offered by the Selling Stockholder and (ii) the aggregate amount of each Selling Stockholder’s liability pursuant to this Section 11(b) shall not exceed the aggregate amount of net proceeds (before deducting expenses) received by such Selling Stockholder from the sale of its ADSs hereunder.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of the Selling Stockholders to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication, any road show or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the third paragraph under the caption “Underwriting” and the information contained in the fifteenth, sixteenth and seventeenth paragraphs relating to stabilizing transactions under the caption “Underwriting.”

(d) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 11, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 11 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 11. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel

shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company and any such separate firm for the Selling Stockholders shall be designated in writing by the Attorneys-in-Fact. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (A) such settlement is entered into more than thirty (30) days after receipt by the Indemnifying Person of such request and (B) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(e) Contribution. If the indemnification provided for in paragraphs (a), (b)or (c) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriters on the other, from the offering of the Offered ADSs 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) but also the relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriters on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriters on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company and the Selling Stockholders from the sale of the Shares and the Offered ADSs and the total underwriting discounts and

commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate initial offering price of the Offered ADSs as set forth on such cover. The relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriters on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Selling Stockholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) Limitation on Liability. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to paragraph (e) above were determined by pro rata allocation (even if the Selling Stockholders were treated as one entity or the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of paragraphs (e) and (f), in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Offered ADSs exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to paragraphs (e) and (f) are several in proportion to their respective purchase obligations hereunder and not joint.

(g) Non-Exclusive Remedies. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

12. Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.

13. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company and the Selling Stockholders, if after the execution and delivery of this Agreement and on or prior to the Closing Date or, in the case of the Option ADSs, prior to the applicable Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by the New York Stock Exchange, the Nasdaq Market, or the Frankfurt Stock Exchange; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State, European Union or German authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States or the Federal Republic of Germany, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Offered ADSs on the Closing Date or the applicable Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus (each of the events set forth in clauses (i) through (iv) above, or the non-occurrence of any condition precedent described in Section 10 hereof or a termination pursuant to Section 14 hereof, a “Termination Event”). With respect to the Underwritten ADSs, upon the occurrence of a Termination Event the following shall apply:

(a) Prior to Filing of a Subscription Certificate. If a Termination Event occurs before the Subscription Certificate for the Underwritten Shares has been filed with the commercial register of the Company, the obligations of the several Underwriters, through the German Subscription Agent, to subscribe for the Underwritten Shares for the account of the several Underwriters and the several obligations of the Underwriters to purchase the Underwritten Shares and the Underwritten ADSs may be canceled and this Agreement may be terminated by the Representatives at their option and in their sole discretion on behalf of the several Underwriters and, in such circumstances, the Company shall return the relevant Subscription Certificate and the relevant Bank Certificate to the German Subscription Agent, and release any funds already credited to the Capital Increase Account for the benefit of the German Subscription Agent, acting for the account of the several Underwriters.

(b) After Filing of Documents for Registration of Capital Increase. If a Termination Event occurs after all documents required for the registration of the capital increase representing the Underwritten Shares have been filed with the commercial register, the Representatives may at their option and in their sole discretion, on behalf of the several Underwriters, terminate this Agreement and request from the Company by written notification to the Company to employ its best efforts to procure a withdrawal of the relevant application for registration of the capital increase representing the Underwritten Shares from the commercial register. If the application is withdrawn successfully, the obligation of the several Underwriters, through the German Subscription Agent, to subscribe for the Underwritten Shares for the account of the several Underwriters and the several obligations of the Underwriters to purchase the Underwritten Shares and the Underwritten ADSs shall terminate and the Company shall return the relevant Subscription Certificate and the relevant Bank Certificate to the German Subscription Agent, and release any funds already credited to the Capital Increase Account for the benefit of the German Subscription Agent, acting for the account of the several Underwriters.

(c) After Registration of Capital Increase or After Application for Registration is not Withdrawn. If a Termination Event occurs after the registration of the capital increase representing the Underwritten Shares with the commercial register or on a date on which the application for the registration of the relevant capital increase representing the Underwritten Shares can no longer be withdrawn, or if despite a request a withdrawal does not occur for other reasons, the following shall apply: the Representatives at their option and in their sole discretion, on behalf of the several Underwriters, may terminate this Agreement; provided, however, that the several obligations of the Underwriters to purchase the Underwritten Shares at the Issue Price shall remain in force and survive any such termination. Subject to the foregoing, in the event of any such termination, the several obligations of the Underwriters towards the Company to purchase the Underwritten Shares and the Underwritten ADSs at the Purchase Price shall terminate. In the event of such termination, no ADS shall have been delivered to investors, and the following shall apply:

(i) The Shares underlying these Underwritten ADSs shall be “Unsold Shares,” as to which the following shall apply:

(A) During a period not exceeding five (5) business days after such termination (the “Unsold Share Period”), the Company may designate one or more shareholders existing as of the date hereof to whom all or a part of the Unsold Shares shall be sold at a purchase price per Unsold Share determined by

the Company, which shall be at least an amount equal to the sum of (a) the Issue Price per Unsold Share plus, (b) any costs and expenses per Unsold Share incurred by the Underwriters in connection with the financing of the Issue Price from the date of the subscription of the Unsold Share to the date of such sale, plus (c) any other costs and expenses per Unsold Share incurred by the Underwriters in connection with or arising from the foregoing procedures, as well as (d) any other costs and expenses per Unsold Share reimbursable pursuant to Section 15. Upon any such sale, to the extent permitted by applicable law, the Underwriters shall as soon as practicable forward to the Company any proceeds of such sale of Unsold Shares less an amount equal to the sum of (a) the Issue Price multiplied by the number of Unsold Shares sold in accordance with this Clause, plus (b) any costs and expenses referred to in the preceding sentence. It is understood by the Company that this clause (c)(i)(A) does not constitute a commitment by the Underwriters to sell the Unsold Shares to such designated shareholders and that such commitment will exist only if and when such shareholders, and at the election of the Underwriters, the Company, enter into definitive arrangements (that may include representations and warranties, covenants, conditions and indemnification) with the Underwriters.

(B) To the extent the Unsold Shares are not sold pursuant to the procedures described in clause (c)(i)(A) during the Unsold Share Period, the Underwriters shall be entitled to sell any or all remaining Unsold Shares (in the form of Ordinary Shares or ADS, at the Underwriters election), to any other person or persons as they determine in their sole discretion, to the extent permitted by applicable law and subject to the inclusion of any securities law legends on any Unsold Shares as in the opinion of counsel for the Underwriters may be necessary. Upon any such sale at a price determined by the Underwriters, to the extent permitted by applicable law, the Underwriters shall as soon as practicable forward to the Company any proceeds received by them from such sale less an amount equal to the sum of (a) the Issue Price multiplied by the number of Unsold Shares sold in accordance with this Clause, (b) any costs and expenses incurred by the Underwriters in connection with the financing of the Issue Price from the date of the subscription of the Unsold Share to the date of such sale, multiplied by the number of Unsold Shares sold in accordance with this Clause, plus (c) any other costs and expenses per Unsold Share incurred by the Underwriters in connection with or arising from the foregoing procedures, as well as (d) any other costs and expenses per Unsold Share reimbursable pursuant to Section 15.

(ii) If the Unsold Shares have already been transferred from the German Subscription Agent to the Depositary and been registered in the Depositary’s name, the Company shall use its best efforts to assist the Underwriters in effecting the transfer of such shares to the German Subscription Agent or any other entity designated by the Underwriters.

14. Defaulting Underwriter.

(a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Offered ADSs that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the

purchase of such Offered ADSs by other persons satisfactory to the Company and the Selling Stockholders on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Offered ADSs, then the Company and the Selling Stockholders shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Offered ADSs on such terms. If other persons become obligated or agree to purchase the Offered ADSs of a defaulting Underwriter, either the non-defaulting Underwriters or the Company and the Selling Stockholders may postpone the Closing Date or the applicable Additional Closing Date, as the case may be, for up to five (5) full business days in order to effect any changes that in the opinion of counsel for the Company, counsel for the Selling Stockholders or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section14, purchases Offered ADSs that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Offered ADSs of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company and the Selling Stockholders as provided in paragraph (a) above, the aggregate number of Offered ADSs that remain unpurchased on the Closing Date or the applicable Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Offered ADSs to be purchased on such date, then the Company and the Selling Stockholders shall have the right to require each non-defaulting Underwriter to purchase the number of Offered ADSs that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Offered ADSs that such Underwriter agreed to purchase on such date) of the Offered ADSs of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Offered ADSs of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company and the Selling Stockholders as provided in paragraph (a) above, the aggregate number of Offered ADSs that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Offered ADSs to be purchased on such date, or if the Company and the Selling Stockholders shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Offered ADSs on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 14 shall be without liability on the part of the Company and the Selling Stockholders, except that the Company and the Selling Stockholders will continue to be liable for the payment of expenses as set forth in Sections 13 and 15 hereof and except that the provisions of Sections 11 and 13 hereof shall not terminate and shall remain in effect. Nothing contained herein shall relieve the Company from any of its obligations contained in Section 13 hereof.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Selling Stockholders or any non-defaulting Underwriter for damages caused by its default.

15. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and the Offered ADSs and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the ADS Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Pricing Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Offered ADSs under the securities laws in accordance with the provisions of Section 7(f) hereof, including the preparation, printing and distribution of a Blue Sky Memorandum, and including the related fees and expenses of counsel for the Underwriters in an aggregate amount not to exceed $5,000; (vi) the costs of preparing share certificates; (vii) the costs and charges of the Depositary and any transfer agent and any registrar; (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA (including the fees and expenses of counsel for the Underwriters related to such filings) in an aggregate amount not to exceed $40,000; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors (provided, however, that the Underwriters and the Company shall each pay 50% of the cost of chartering any aircraft to be used in connection with the road show by both the Company and the Underwriters, and all lodging, commercial airfare and individual expenses of the Underwriters shall be the responsibility of the Underwriters); and (x) all expenses and application fees related to the listing of the Offered ADSs on the Nasdaq Market. The Selling Stockholders will pay or cause to be paid all costs and expenses incident to the performance of their obligations hereunder.

(b) If (i) this Agreement is terminated pursuant to Section 13, (ii) the Company or the Selling Stockholders for any reason fail to tender the Shares or Offered ADSs for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares or the Offered ADSs for any reason permitted under this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby. It is understood that the Company and the Selling Stockholders shall not pay or reimburse any costs, fees or expenses incurred by any Underwriter that defaults on its obligations to purchase the Offered ADSs.

16. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 11 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Offered ADSs from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

17. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Selling Stockholders and the Underwriters contained in this Agreement (including those contained in Section 13 hereof) or made by or on behalf of the Company, the Selling Stockholders or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Shares and the Offered ADSs and shall remain in

full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Selling Stockholders or the Underwriters or the directors, officers, controlling persons or affiliates referred to in Section 11 hereof.

The foregoing indemnity shall constitute a separate and independent obligation of the Company and each Selling Stockholder and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid.

Re:	BioNTech SE – Public Offering

Ladies and Gentlemen:

The undersigned understands that you, each as one of several Representatives of the several underwriters, propose to enter into an underwriting agreement (the “Underwriting Agreement”) with BioNTech SE, a European stock corporation (Societas Europaea) incorporated in Germany and governed by the laws of the European Union and the Federal Republic of Germany and registered with the commercial register (Handelsregister) of the local court (Amtsgericht) of Mainz, the Federal Republic of Germany (the “Company”), providing for the public offering (the “Public Offering”) by the several underwriters named in Schedule 1 to the Underwriting Agreement (the “Underwriters”), of ordinary shares with no par value and a nominal value attributable to each share of €1.00 (the “Ordinary Shares”) of the Company in the form of American Depositary Shares (“ADSs,” and together with Ordinary Shares, the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the ADSs, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of X.X. Xxxxxx Securities LLC and BofA Securities, Inc. on behalf of the Underwriters, the undersigned will not, during the period beginning on the date of this letter agreement (this “Letter Agreement”) and ending 90³ days after the date of the prospectus relating to the Public Offering (the “Prospectus”) (such period, the “Restricted Period”), (1)

Exh. D-1

offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Securities of the Company or any securities convertible into or exercisable or exchangeable for Ordinary Shares (including without limitation, Securities, restricted shares, share options or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and securities which may be issued upon exercise of a stock option or warrant), or publicly disclose the intention to undertake any of the foregoing, (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of any Securities or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Securities or such other securities, in cash or otherwise, or (3) make any demand for or exercise any right with respect to the registration of any Securities or any security convertible into or exercisable or exchangeable for Securities. The undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transactions designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition of any Securities, or securities convertible into or exercisable or exchangeable for Ordinary Shares, even if any such sale or disposition transaction or transactions would be made or executed by or on behalf of someone other than the undersigned. Notwithstanding the foregoing, the terms of this Letter Agreement shall not apply to or prohibit:

(E) transfers or dispositions of Securities or any security convertible into or exercisable or exchangeable for Securities (i) by will, other testamentary document or intestacy, (ii) to any Family Member of the undersigned, (iii) to any trust for the direct or indirect benefit of the undersigned or a Family Member of the undersigned, or (iv) if the undersigned is a trust, to the trustee on behalf of the beneficiary or to the beneficiary of such trust or to the estate of a beneficiary of such trust,

(F) transfers of Securities or any security convertible into or exercisable or exchangeable for Securities by operation of law pursuant to a domestic order, negotiated divorce settlement or other court order, provided that no public announcement or voluntary filing shall be made and if a filing by any party
