The Underwritten Shares and the Option Shares are herein referred to as the “Shares”. The shares of Class A Common Stock of the Company to be outstanding after giving effect to the sale of the Shares are referred to herein as the “Stock”.

In connection with the offering contemplated by this Agreement, the “Transactions” (as such term is defined in the Registration Statement and the Preliminary Prospectus (each as defined below) under the caption “Transactions”) were or will be effected, pursuant to which the Company will become the sole managing member of Bioventus LLC, a Delaware limited liability company (“Holdings”), and will operate and control all of the business and affairs of Holdings and, through Holdings and its subsidiaries, conduct its business. The Company and Holdings are collectively referred to herein as the “Bioventus Parties.”

▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇”) has agreed to reserve a portion of the Shares to be purchased by it under this Agreement for sale to certain of the Company’s and its subsidiaries’ directors, officers, employees and business associates (collectively, “Participants”), as set forth in the Preliminary Prospectus (as defined below) under the heading “Underwriters” (the “Reserved Share Program”). The Shares to be sold by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ pursuant to the Reserved Share Program, at the direction of the Company, are referred to hereinafter as the “Reserved Shares”. Any Reserved Shares not orally confirmed for purchase by any Participant by 7:00 A.M. (New York time) of the business day immediately following the business day on which this Agreement is executed will be returned to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ to be reallocated as set forth in the Prospectus.

Each Bioventus Party hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Shares, 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 (File No. 333-237482), including a prospectus, relating to the Shares. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A 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 confirmation of sales of the Shares. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (a “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. 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, the “Pricing Disclosure Package”): a Preliminary Prospectus dated [•], 2021 and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

“Applicable Time” means [•] [A/P].M., New York City time, on [•], 2021.

2. Purchase of the Shares by the Underwriters.

(a) The Company agrees to issue and sell the Underwritten Shares to the several Underwriters as provided in this underwriting agreement (this “Agreement”), and 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 purchase at a price per share of $[•] (the “Purchase Price”) from the Company the respective number of Underwritten Shares set forth opposite such Underwriter’s name in Schedule 1 hereto.

In addition, the Company agrees to issue and sell the Option Shares 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 the Company the Option Shares at the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Underwritten Shares but not payable on the Option Shares.

If any Option Shares are to be purchased, the number of Option Shares to be purchased by each Underwriter shall be the number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Underwritten Shares set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 10 hereof) bears to the aggregate number of Underwritten Shares being purchased from the Company by the several Underwriters, subject, however, to such adjustments to eliminate any fractional Shares as the Representatives in their sole discretion shall make.

The Underwriters may exercise the option to purchase Option Shares at any time in whole, or from time to time in part, on or before the thirtieth day following the date of the Prospectus, by written notice from the Representatives to the Company. Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when the Option Shares 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 or later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10 hereof). Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(b) The Company understands that the Underwriters intend to make a public offering of the Shares, and initially to offer the Shares on the terms set forth in the Pricing Disclosure Package. The Company acknowledges and agrees that the Underwriters may offer and sell Shares to or through any affiliate of an Underwriter.

(c) Payment for the Shares shall be made by wire transfer in immediately available funds to the account specified by the Company to the Representatives in the case of the Underwritten Shares, at the offices of ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP at 10:00 A.M., New York City time, on [•], 2021, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing or, in the case of the Option Shares, on the date and at the time and place specified by the Representatives in the written notice of the Underwriters’ election to purchase such Option Shares. The time and date of such payment for the Underwritten Shares is referred to herein as the “Closing Date”, and the time and date for such payment for the Option Shares, if other than the Closing Date, is herein referred to as the “Additional Closing Date”.

Payment for the Shares to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made against delivery to the Representatives for the respective accounts of the several Underwriters of the Shares to be purchased on such date or the Additional Closing Date, as the case may be, with any transfer taxes payable in connection with the sale of such Shares duly paid by the Company. Delivery of the Shares shall be made through the facilities of The Depository Trust Company (“DTC”) unless the Representatives shall otherwise instruct.

(d) Each Bioventus Party acknowledges and agrees that (i) the Representatives and the other Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Bioventus Parties with respect to the offering of Shares 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

Bioventus Parties or any other person and (ii) none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to any entity or natural person. Additionally, neither the Representatives nor any other Underwriter are advising the Bioventus Parties or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Bioventus Parties shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representative nor the other Underwriters shall have any responsibility or liability to the Bioventus Parties with respect thereto. Any review by the Representatives and the other Underwriters of the Bioventus Parties, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Bioventus Parties. Each of the Bioventus Parties waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

any event or development shall occur or condition shall exist as a result of which the Pricing Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Pricing Disclosure Package is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Pricing Disclosure Package to comply with law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate such amendments or supplements to the Pricing Disclosure Package as may be necessary so that the statements in the Pricing Disclosure Package as so amended or supplemented will not, in the light of the circumstances existing when the Pricing Disclosure Package is delivered to a purchaser, be misleading or so that the Pricing Disclosure Package will comply with law.

(a) Indemnification of the Underwriters. Each Bioventus Party, jointly and severally, 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, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment or supplement thereto) or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus (or any amendment or supplement thereto), the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, any Testing-the-Waters Communication, any road show as defined in Rule 433(h) under the Securities Act (a “road show”) or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, 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 therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in paragraph (b) below.

(b) Indemnification of the Bioventus Parties. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless each Bioventus Party, the directors of the Company, the officers 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 Securities Act or Section 20 of the Exchange Act 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 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 twelfth paragraph under the caption “Underwriting” relating to price stabilization, short positions and penalty bids.

(c) 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 either paragraph (a) or (b) above, 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 paragraph (a) or (b) above 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 paragraph (a) or (b) above. 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 in such proceeding and shall pay the reasonably incurred 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 interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonably incurred 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, upon receipt from the Indemnified Person of a written request for payment thereof accompanied by a written statement with reasonable supporting detail of such fees and expenses. 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 Bioventus Parties, the directors of the Company, the officers of the Company who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. 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 (i) such settlement is entered into more than (A) 60 days after receipt by the Indemnifying Person of such request and (B) 60 days after receipt by the Indemnifying Person of the proposed terms of such settlement and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement, unless, in each case, the amount of such fees and expenses is being actively disputed in good faith. 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.

(d) Contribution. If the indemnification provided for in paragraph (a) or (b) 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 Bioventus Parties, on the one hand, and the Underwriters on the other, from the offering of the Shares 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 Bioventus Parties, 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 Bioventus Parties, 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 from the sale of the Shares 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 offering price of the Shares. The relative fault of the Bioventus Parties, 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 Bioventus Parties or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Bioventus Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to paragraph (d) above 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 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 (d) above shall be deemed to include, subject to the limitations set forth

above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of paragraphs (d) and (e), 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 Shares 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 (d) and (e) are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 paragraphs (a) through (e) 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.

(g) Reserved Share Program Indemnification.

(i) Each Bioventus Party, jointly and severally, agrees to indemnify and hold harmless ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, each person, if any, who controls ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ within the meaning of Rule 405 of the Securities Act (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities”) from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with defending or investigating any such action or claim, as such fees and expenses are incurred) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Bioventus Parties for distribution to Participants in connection with the Reserved Share Program or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) caused by the failure of any Participant to pay for and accept delivery of Reserved Shares that the Participant agreed to purchase; or (iii) related to, arising out of, or in connection with the Reserved Share Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities.

(ii) In case any proceeding (including any governmental investigation) shall be instituted involving any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity in respect of which indemnity may be sought pursuant to Section 7(g)(i), the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity seeking indemnity, shall promptly notify the Bioventus Parties in writing and the Bioventus Parties, upon request of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity, shall retain counsel reasonably satisfactory to the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity to represent the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity and any others the Bioventus Parties may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity unless (i) the Bioventus Parties shall have agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both a Bioventus Party and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The

Bioventus Parties shall not, in respect of the legal expenses of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities in connection with any proceeding or related proceedings 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 ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities. Any such separate firm for the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities shall be designated in writing by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇. The Bioventus Parties shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, each Bioventus Party, jointly and severally, agrees to indemnify the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time a ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity shall have requested the Bioventus Parties to reimburse it for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, each Bioventus Party, jointly and severally, agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by the Bioventus Parties of the aforesaid request and (ii) the Bioventus Parties shall not have reimbursed the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity in accordance with such request prior to the date of such settlement, unless, in each case, the amount of such fees and expenses is being actively disputed in good faith. The Bioventus Parties shall not, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, effect any settlement of any pending or threatened proceeding in respect of which any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity is or could have been a party and indemnity could have been sought hereunder by such ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity, unless such settlement includes an unconditional release of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities from all liability on claims that are the subject matter of such proceeding.

(iii) To the extent the indemnification provided for in Section 7(g)(i) is unavailable to a ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Bioventus Party, jointly and severally, in lieu of indemnifying the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity thereunder, shall contribute to the amount paid or payable by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity 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 Bioventus Parties on the one hand and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities on the other hand from the offering of the Reserved Shares or (ii) if the allocation provided by clause 7(g)(iii)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 7(g)(iii)(i) above but also the relative fault of the Bioventus Parties on the one hand and of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities on the other hand in connection with any 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 Bioventus Parties on the one hand and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities on the other hand in connection with the offering of the Reserved Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Reserved Shares (before deducting expenses) and the total underwriting discounts and commissions received by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities for the Reserved Shares, bear to the aggregate Public Offering Price of the Reserved Shares. If the loss, claim, damage or liability is caused by an untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact, the relative fault of the Bioventus Parties on the one hand and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement or the omission or alleged omission relates to information supplied by the Bioventus Parties or by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(iv) The Bioventus Parties and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities agree that it would not be just or equitable if contribution pursuant to Section 7(g)(iii) above were determined by pro rata allocation (even if the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities 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 Section 7(g)(iii). The amount paid or payable by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities in connection with investigating or defending any such action or claim. Notwithstanding the provisions of Section 7(g)(iii) above, no ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity shall be required to contribute any amount in excess of the amount by which the total price at which the Reserved Shares distributed to the public were offered to the public exceeds the amount of any damages that such ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity has otherwise been required to pay. 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 remedies provided for in this Section 7(g) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(v) The indemnity and contribution provisions contained in this Section 7(g) shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Reserved Shares.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange or The Nasdaq Stock Market; (ii) trading of any securities issued or guaranteed by any Bioventus Party 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 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, 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 Shares on the Closing Date or the 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.

10. 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 Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company 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 Shares, then the Company shall be entitled to a further period of 36 hours within which to procure other persons reasonably satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company 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 Section 10, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares 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 Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares 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 Shares to be purchased on such date, or if the Company 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 Shares on the Additional Closing Date shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Bioventus Parties, except that each Bioventus Party will continue to be jointly and severally liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

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

11. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Bioventus Parties will, jointly and severally, 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 any transfer or other taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the 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 of the Shares under the state or foreign securities or blue sky laws of such jurisdictions as the Representatives may reasonably designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonably incurred fees and expenses of counsel for the Underwriters); (vi) the cost of preparing stock certificates; (vii) the costs and charges of 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, provided that the aggregate amount payable by the Company pursuant to clauses (v) and (viii) shall not exceed $35,000; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; provided that any expenses or costs associated with any chartered plane used in connection with any “road show” presentation to potential investors will be paid 50% by the Company and 50% by the Underwriters; (x) all expenses and application fees related to the listing of the Shares on The Nasdaq Global Market and (xi) all fees and disbursements of counsel incurred by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ in connection with the Reserved Share Program and stamp duties, similar taxes or duties or other taxes, if any, incurred by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ in connection with the Reserved Share Program. It is agreed that, except as specifically provided in this Section 11 and as otherwise contemplated in Section 7 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel.

(b) If (i) this Agreement is terminated pursuant to Section 9, (ii) the Company for any reason fails to tender the Shares for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares for any reason permitted under this Agreement, the Bioventus Parties agree, jointly and severally, 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. For the avoidance of doubt, it is understood that the Bioventus Parties shall not pay or reimburse any costs, fees or expenses incurred by any Underwriter that defaults on its obligations to purchase the Shares.

12. 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 in Section 7 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 Shares from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Bioventus Parties and the Underwriters contained in this Agreement or made by or on behalf of the Bioventus Parties or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Shares 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 Bioventus Parties or the Underwriters, or the directors, officers, controlling persons or affiliates referred to in Section 7 hereof.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

(b) 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 applicable to agreements made and to be performed in such state.

(i) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

To Whom It May Concern:

In reliance on Section 5(d) of and/or Rule 163B under the Securities Act of 1933, as amended (the “Act”), Bioventus Inc. (the “Issuer”) hereby authorizes ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇”), ▇.▇. ▇▇▇▇▇▇ Securities LLC (“▇.▇. ▇▇▇▇▇▇”), and ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Co. LLC (“▇▇▇▇▇▇▇ Sachs”) and their respective affiliates and employees (the “Authorized Underwriters”), to act on behalf of the Issuer in undertaking oral and written communications with potential investors that are, or are reasonably believed to be, “qualified institutional buyers,” as defined in Rule 144A under the Act, or institutions that are, or are reasonably believed to be, “accredited investors,” as defined in Regulation D under the Act, to determine whether such investors might have an interest in the Issuer’s contemplated initial public offering (“Testing-the-Waters Communications”) in the United States. A “Written Testing-the-Waters Communication” means any Testing-the-Waters Communication that is a written communication within the meaning of Rule 405 under the Act. Any Written Testing-the-Waters Communication shall be subject to prior approval by the Issuer’s Chief Financial Officer prior to its dissemination to a potential investor, provided, however, that no such approval shall be required for any written communication that is administrative in nature (i.e., scheduling meetings) or that solely contains information already contained in a communication previously approved by the Issuer. The Issuer has advised the Authorized Underwriters that it does not intend to provide or authorize any written communications to potential investors other than communications that are solely administrative in nature.

The Issuer represents that (i) except as disclosed to the Authorized Underwriters, it has not alone engaged in any Testing-the-Waters Communication and (ii) it has not authorized anyone other than the Authorized Underwriters to engage in Testing-the-Waters Communications. The Issuer agrees that it shall not authorize any other third party to engage on its behalf in oral or written communications with potential investors without the written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇.▇. ▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇▇▇▇▇. The Issuer also represents that, as of the date hereof, it is an “emerging growth company,” as defined in Section 2(a) of the Act (an “Emerging Growth Company”). The Issuer agrees to promptly notify the Authorized Underwriters in writing if the Issuer hereafter ceases to be an Emerging Growth Company while this authorization is in effect.

If at any time following the distribution of any Written Testing-the-Waters Communication there occurred or occurs an event or development as a result of which such Written Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in light of the circumstances existing at that subsequent time, not misleading, the Issuer will promptly notify the Authorized Underwriters and will promptly amend or supplement, at its own expense, such Written Testing-the-Waters Communication to eliminate or correct such untrue statement or omission.

Nothing in this authorization is intended to limit or otherwise affect the ability of the Authorized Underwriters, to engage in communications in which they could otherwise lawfully engage in the absence of this authorization, including, without limitation, any written communication containing only one or more of the statements specified under Rule 134(a) under the Act. This authorization shall remain in effect until the Issuer has provided to the Authorized Underwriters a written notice revoking this authorization. All notices as described herein shall be sent by email to the attention of ▇▇▇▇▇.▇▇▇▇▇▇@▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇, ▇▇▇▇▇.▇▇@▇▇▇▇▇▇▇▇.▇▇▇ and ▇▇▇▇▇▇▇▇.▇▇▇▇▇▇▇@▇▇.▇▇▇.

Re: BIOVENTUS INC. — Public Offering

Ladies and Gentlemen:

The undersigned understands that you, as Representatives of the several Underwriters (the “Representatives”), propose to enter into an underwriting agreement (the “Underwriting Agreement”) with Bioventus Inc., a Delaware corporation (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 Class A Common Stock, $0.001 per share par value (“Class A Common Stock”) of the Company. 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 Class A Common Stock, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, the undersigned will not, and will not cause any direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended (the “Securities Act”)) to, during the period (the “Lock-up Period”) beginning on the date hereof and ending at the close of business 180 days after the date of the final prospectus (the “Prospectus”) relating to the Public Offering, (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 shares of Class A Common Stock or Class B Common Stock, $0.001 per share par value, of the Company (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”) or any securities convertible into or exercisable or exchangeable for any shares of Common Stock (including without limitation, options or warrants to purchase Common Stock and limited liability company interests in Bioventus LLC (the “LLC Interests” and, together with the Common Stock, the “Securities”) or such other Securities which may be deemed to be beneficially owned (as defined in the Securities Exchange Act of 1934, as amended (the “Exchange Act”) by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Securities which may be issued upon exercise of a stock option or warrant (any such securities described in this clause (1), the “Restricted Securities”)), (2) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the Restricted Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of the Restricted Securities, in cash or otherwise, (3) make any demand for or exercise any right with respect to the registration of any Restricted Securities, or (4) publicly disclose the intention to do any of the foregoing; provided that, for the avoidance of doubt, to the extent the undersigned has demand and/or piggyback registration rights, the foregoing shall not prohibit the undersigned from notifying the Company privately that it is or will be exercising its demand and/or piggyback registration rights following the expiration of the Lock-Up Period and undertaking preparations related thereto, including confidential submission of a registration statement with the United States Securities and Exchange Commission (the “SEC”). 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 Restricted Securities, 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.

(F) transfers of Restricted Securities to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (B) through (E) above.

(G) if the undersigned is a corporation, partnership, LLC, trust or other business entity, transfers of Restricted Securities (A) to another corporation, partnership, LLC, trust or other business entity that is an affiliate (as defined above) of the undersigned, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the undersigned or affiliates of the undersigned (including, for the avoidance of doubt, where the undersigned is a partnership, to its general partner or a successor partnership or fund, or any other funds managed by such partnership), or (B) as part of a distribution to members or shareholders or other holders of equity interests of the undersigned;

(J) transfers of Restricted Securities that occur by operation of law, such as pursuant to a qualified domestic order, divorce settlement, divorce decree or separation agreement;

(K) transfers of Restricted Securities to the Company from an employee of the Company upon death, disability or termination of employment, in each case, of such employee;

(L) transactions of Restricted Securities acquired in open market transactions after the completion of the Public Offering;

(M) entry into a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act for the transfer of Restricted Securities; provided that such plan does not provide for the transfer of Restricted Securities during the Lock-up Period; or

(O) any restructuring transactions to effectuate the “Up-C” structure and related Transactions (as defined in the Pricing Disclosure Package) in the manner set forth in the Registration Statement, the Pricing Disclosure Package and the Prospectus;

provided that in the case of any transfer or distribution pursuant to (1) clauses (B) through (H) or (J), such transfer, donation or distribution shall not involve a disposition for value and each donee, devisee, transferee or distributee shall execute and deliver to the Representatives a lock-up letter in the form of this Letter Agreement; (2) clauses (B) through (H), (L) or the entry into any plan contemplated by clause (M), no filing by any party (donor, donee, devisee, transferor, transferee, distributer, distributee or plan entrant) under the Exchange Act, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution or plan entrance, plan establishment or plan existence (other than a filing on a Form 5 made after the expiration of the Lock-up Period); and (3) clause (J) or (K), it shall be a condition to such transfer that no public filing, report or announcement shall be voluntarily made and if any filing under Section 16(a) of the Exchange Act, or other public filing, report or announcement reporting a reduction in beneficial ownership of shares of Common Stock in connection with such transfer or distribution shall be legally required during the Lock-up Period, such filing, report or announcement shall clearly indicate in the footnotes thereto the nature and conditions of such transfer.

If any of the entities listed on Schedule A hereto or any of their respective transferee of a Permitted Transfer (as defined in the Second Amended and Restated Limited Liability Company Agreement) (each such entity, an “Institutional Stockholder”) or any other transferee that receives Restricted Securities directly or indirectly from any Institutional Stockholder (collectively, but excluding the undersigned, the “Triggering Stockholders”), is granted a release or waiver from any lock-up agreement executed with the Representatives in connection with the Public Offering prior to the expiration of the Lock-up Period, then the undersigned shall also be granted an early release from its obligations hereunder on the same terms and on a pro-rata basis with respect to such number of Restricted Securities (provided that, for such purposes, one share of Class B Common Stock and one LLC Interest shall count as one Restricted Security) rounded down to the nearest whole security equal to the product of (i) the total percentage of Restricted Securities (assuming the conversion, exercise or exchange of any securities convertible into or exercisable or exchangeable for shares of Common Stock) held by the Triggering Stockholder immediately following the consummation of the Public Offering that are being released from the lock-up agreement multiplied by (ii) the total number of Restricted Securities (assuming the conversion, exercise or exchange of any securities convertible into or exercisable or exchangeable for shares of Common Stock) held by the undersigned immediately following the consummation of the Public Offering. Notwithstanding the foregoing, if such early release or waiver is granted in connection with an underwritten public offering of Common Stock registered pursuant to the Securities Act (a “Secondary Offering”), then the securities of the undersigned shall only be granted an early release, on a pro rata basis with and otherwise on the same terms as any other security holders in such Secondary Offering, with respect to such number of shares of Common Stock held by the undersigned that are sold in such Secondary Offering (or, in the case of a “synthetic secondary offering,” the number of shares of Common Stock held by the undersigned that are repurchased by the Company, Bioventus LLC or other Bioventus Parties from the net proceeds of Common Stock sold in such Secondary Offering). The provisions of this paragraph will not apply unless and until the Representatives have waived such prohibitions or released any party or parties locked-up in connection with the Public Offering with respect to Restricted Securities in respect of 2% in the aggregate of (x) prior to consummation of the Public Offering, the outstanding Restricted Securities or (y) post consummation of the Public Offering, the outstanding shares of Series A Common Stock, in each case, subject to restrictions similar to those included in this Letter Agreement. The Representatives shall use reasonable efforts to provide notice to the undersigned upon the occurrence of a release of a Triggering Stockholder of its obligations under any lock-up agreement executed in connection with the Public Offering that gives rise to a corresponding release of the undersigned’s lock-up pursuant to the terms of this paragraph; provided that the failure to

provide such notice shall not give rise to any claim or liability against the Representatives or the Underwriters. In addition, in the event the Representatives agree to less restrictive or otherwise more favorable terms in any lock-up agreement executed in connection with the Public Offering by an Institutional Stockholder other than the undersigned, such terms will automatically apply to this Letter Agreement. The terms of this paragraph only apply if the undersigned is an Institutional Stockholder.

[If the undersigned is not a natural person, the undersigned represents and warrants that no single natural person, entity or “group” (within the meaning of Section 13(d)(3) of the Exchange Act) beneficially owns, directly or indirectly, 50% or more of the common equity interests, or 50% or more of the voting power, in the undersigned.]

[If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any Company-directed Class A Common Stock the undersigned may purchase in the Public Offering.]

If the undersigned is an officer or director of the Company, (i) the Representatives, on behalf of the Underwriters agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Restricted Securities, the Representatives, on behalf of the Underwriters will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives, on behalf of the Underwriters hereunder to any such officer or director shall only be effective two business days after the publication date of such announcement. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration or that is to an immediate family member as defined in FINRA Rule 5130(i)(5) and (b) the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned acknowledges and agrees that the Underwriters have not provided any recommendation or investment advice nor have the Underwriters solicited any action from the undersigned with respect to the Public Offering of the Class A Common Stock and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriters may provide certain Regulation Best Interest and Form C RS disclosures or other related documentation to you in connection with the Public Offering, the Underwriters are not making a recommendation to you to participate in the Public Offering or sell any Shares at the price determined in the Public Offering, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

The undersigned understands that, if (a) the Underwriting Agreement does not become effective by June 15, 2021, (b) if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, (c) either the Company, on the one hand, or the Representatives, on the other hand, notifies the other in writing that it does not intend to proceed with the Public Offering or (d) the registration statement filed with the SEC in connection with the Public Offering is withdrawn, the undersigned shall be released from, all obligations under this Letter Agreement. The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this Letter Agreement.

This Letter Agreement and any claim, controversy or dispute arising under or related to this Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York.
