Re: Initial Public Offering

Ladies and Gentlemen:

This letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and between among Biotech Group Acquisition Corporation, a Delaware corporation (the “Company”), and US Tiger Securities, Inc. (“US Tiger”), relating to an underwritten initial public offering (the “Public Offering”), of up to 7,500,000 of the Company’s units (including up to 1,125,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), and one redeemable warrant. Each Warrant (each, a “Warrant”) entitles the holder thereof to purchase one share of Class A Common Stock at a price of $11.50 per share, subject to adjustment. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”) and the Units have been approved to be listed on the Nasdaq Global Market. Certain capitalized terms used herein are defined in paragraph 12 hereof.

In order to induce the Company and US Tiger, as a representative (the “Representative”) of the several underwriters (the “Underwriters”) to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Biotech Group Acquisition Sponsor LLC (the “Sponsor”) and each of the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team or a personnel of the Company or a designee of them (each, an “Insider” and collectively, the “Insiders”) (the Sponsor, the Insiders and their affiliates or designees, together the “Initial Stockholders”), hereby agrees with the Company as follows:

1. Each of the Initial Stockholders agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, it, he or she shall (A) vote any shares of Capital Stock owned by it, him or her in favor of any proposed Business Combination, (B) not to propose, or vote in favor of, prior to and unrelated to an initial Business Combination, an amendment to the amended and restated certificate of incorporation of the Company that would affect the substance or timing of the Company’s redemption obligation to redeem all Public Shares (defined below) if the Company cannot complete an initial Business Combination within the Completion Period (defined below), unless the Company provides public stockholders an opportunity to redeem their Public Shares in conjunction with any such amendment, (C) not to redeem any Founder Shares or Private Shares held by it, him or her into the right to receive cash from the Trust Account in connection with a stockholder vote to approve our proposed initial Business Combination or sell any shares to the Company in any tender offer in connection with the proposed initial Business Combination, and (D) that the Founder Shares and Private Shares shall not participate in any liquidating distribution upon winding up if a Business Combination is not consummated within the Completion Period. For purposes of this agreement, the “Completion Period” refers to the period following the completion of this offering at the end of which, if we have not completed our initial business combination, we will redeem 100% of the public shares at a per share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, if any (less up to $75,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, subject to applicable law and certain conditions and as further described herein. Pursuant to the amended and restated certificate of incorporation of the Company, the Completion Period ends 12 months from the closing of the Public Offering, which may be extended up to two times by an additional three-month period each time for a total of 18 months from the closing of the Public Offering.

2. The Sponsor and each Insider agree that in the event that the Company fails to consummate a Business Combination within the Completion Period or such later period approved by the Company’s stockholders in accordance with the Company’s amended and restated certificate of incorporation, the Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 business days thereafter, subject to lawfully available funds therefor, redeem 100% of shares of Class A Common Stock sold as part of the Units in the Public Offering (the “Public Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $75,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish all Public Stockholders’ rights as stockholders of the Company (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable law.

3. Each of the Initial Stockholders acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares or Private Shares held by it, him or her. The Sponsor and each Insider hereby further waive, with respect to any shares of Class A Common Stock held by it, him or her, if any, any redemption rights it, he or she may have in connection with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase shares of Common Stock (although the Initial Stockholders shall be entitled to redemption and liquidation rights with respect to any Public Shares it or they hold if the Company fails to consummate a Business Combination within the Completion Period).

4. In the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other shareholders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may become subject as a result of any claim by (i) any third party (other than the Company’s independent accountants) for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement for a Business Combination agreement (a “Target”); provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.25 per share of the Public Shares or (ii) such lesser amount per share of the Public Shares held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to pay taxes, except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability for such third party claims. The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.

5. To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 1,125,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number of Founder Shares in the aggregate equal to the product of 281,250 multiplied by a fraction, (i) the numerator of which is 1,125,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 1,125,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Initial Stockholders will own an aggregate of 20.0% of the Company’s issued and outstanding shares of Capital Stock after the Public Offering (assuming that our Sponsor and the Insiders do not purchase any Public Shares or Units in the Public Offering).

6. In the event that the Company fails to consummate a Business Combination within 12 months of the closing of the Public Offering, the Sponsor or its affiliates may request Company to extend the period of time for the Company to consummation a Business Combination up to two times by an additional three-month period each time for a total of up to 18 months of the closing of the Public Offering. If the Sponsor requests an extension, the Sponsor, its affiliates or designees shall deposit into the Trust Account an amount equal to $750,000 (or up to $862,500 if the over-allotment option is exercised), representing $0.10 for each Public Share upon five days advance notice prior to the applicable deadline. The Sponsor, its affiliates or designees will receive a non-interest bearing, unsecured promissory note equal to the amount of any such deposit either be paid upon consummation of the initial Business Combination solely from funds available outside of the Trust Account or, at the relevant Insider’s discretion, converted upon consummation of the Business Combination into Working Capital Units at a price of $10.00 per Working Capital Unit. Pursuant to this Letter Agreement, the Sponsor, its affiliates or designees have agreed to waive their right to be repaid for such notes in the event that the Company fails to complete a Business Combination.

7. The Sponsor and each Insider hereby agree and acknowledge that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 8(a), 8(b), and 10 of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

8. (a) The Sponsor and each Insider agree that it, he or she shall not Transfer 50% of its Founder Shares until the earlier to occur of: (A) six months after the completion of the Company’s initial Business Combination, or (B) the date on which the closing price of the Company’s Class A Common Stock equals or exceeds $12.50 per share (as adjusted for share splits, share dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing after the completion of the Company’s initial Business Combination; and shall not Transfer the remaining 50% of the Founder Shares until the six months after the completion of the Company’s initial Business Combination, or earlier, in either case, if, subsequent to the Company’s initial Business Combination, the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property (the “Founder Shares Lock-up Period”).

(b) Each of the Sponsor and their affiliates or designees agrees that it, he or she shall not Transfer any Private Units or Working Capital Units until after 30 days after the completion of a Business Combination (the “Private Units Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

(c) Notwithstanding the provisions set forth in paragraphs 8(a) and (b), Transfers of the Founder Shares, Private Units, or Working Capital Units that are held by the Initial Stockholders or any of their permitted transferees (that have complied with this paragraph 8(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members of the Sponsor or any of their affiliates, officers, directors, direct and indirect equity holders; (b) in the case of an individual, by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to a qualified domestic relations order; (e) transfers by private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which the securities were originally purchased; (f) transfers in the event of the Company’s liquidation prior to the completion of an initial Business Combination; and (g) transfers by virtue of the laws of the State of Delaware or the Sponsor’ limited liability company agreement upon dissolution of the Sponsor; provided, however, that in the case of clauses (a) through (e) or (g), these permitted transferees must enter into a written agreement agreeing to be bound by the restrictions herein.

9. Each of the Sponsor and the Insiders represents and warrants that it, he or she has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to the Insider’s background.
