sell, the Securities at the Closing. Subsequent to Closing, upon request of an Investor, the Company shall deliver or cause to be delivered to such Investor within five (5) Business Days of such request a book-entry statement of account from the Company’s transfer agent reflecting the issuance of the Securities.

3. Representations and Warranties of the Company. Except as set forth in the SEC Reports (other than as to the Fundamental Representations, which are not so qualified), the Company hereby represents and warrants to each of the Investors and the Placement Agents that the statements contained in this Section 3 are true and correct as of the date of this Agreement and as of the Closing Date (except for the representations and warranties that speak as of a specific date, which shall be made as of such date).

3.1 Organization, Good Standing, Corporate Power and Qualification. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business as now conducted and as presently proposed to be conducted. The Company is duly qualified to transact business and is in good standing in each jurisdiction in which the failure to so qualify would have a Material Adverse Effect. As of the date hereof, the Company has the following subsidiaries: AVRIOBIO Inc., AVROBIO Australia Pty Ltd, AVROBIO Securities Corporation, Tectonic Therapeutic Pty Ltd., Tectonic Therapeutic Securities Corp. and Tectonic Operating Company, Inc. (the “Subsidiaries”). Each of the Subsidiaries is (i) duly incorporated and validly existing and in good standing under the laws of the jurisdiction of its incorporation and has the requisite power and authority to carry on its business as now conducted and to own or lease its properties and (ii) qualified to do business as a foreign corporation and in good standing in each jurisdiction in which such qualification is required, except in each case as would not cause a Material Adverse Effect.

3.2 Capitalization. The authorized capital stock of the Company consists of 150,000,000 shares of Common Stock and 10,000,000 shares of Preferred Stock. The Company’s disclosure of its authorized, issued and outstanding capital stock in the most recent SEC Report containing such disclosure was accurate in all material respects as of the date indicated in such SEC Reports and the Company has not issued any capital stock since its most recently filed periodic report under the Exchange Act, other than pursuant to the exercise of employee stock options under the Company’s stock option plans. All of the issued and outstanding shares of Common Stock have been duly authorized and validly issued and are fully paid and non-assessable. None of the outstanding shares of capital stock of the Company were issued in violation of any preemptive or other similar rights of any securityholder of the Company which have not been waived, and such shares were issued in compliance in all material respects with applicable state and federal securities law and any rights of third parties. The issuance and sale of the Securities hereunder will not obligate the Company or any Subsidiary to issue shares of Common Stock or other securities to any Person (other than the Investors). No further approval or authorization of any stockholder, the Board or others is required for the issuance and sale of the Securities. There are no securities or instruments issued by or to which the Company is a party containing anti-dilution or similar provisions that will be triggered by the issuance of the Securities pursuant to this Agreement.

3.3 Registration Rights. Except as set forth in the Transaction Agreements or as disclosed in the SEC Reports, the Company is presently not under any obligation, and has not granted any rights, to register under the Securities Act any of the Company’s presently outstanding securities or any of its securities that may hereafter be issued, other than such rights and obligations that have expired or been satisfied or waived.

3.4 Authorization. All corporate action required to be taken by the Board and stockholders of the Company in order to authorize the Company to enter into this Agreement and to issue the Securities at the Closing has been taken or will be taken prior to the Closing. A committee of the Board comprised solely of independent directors who are not Investors or Affiliates of any Investor has approved the transactions contemplated by the Transaction Agreements. The execution and delivery of the Transaction Agreements and the consummation of the transactions contemplated by the Transaction Agreements by the Company have been duly authorized by all necessary corporate action on the part of the Company. All action on the part of the Board and officers of the Company necessary for the execution and delivery of the Transaction Agreements, the performance of all obligations of the Company under this Agreement to be performed as of the Closing, the issuance and delivery of the Securities has been taken or will be taken prior to the Closing. This Agreement, when executed and delivered by the Company, assuming the due authorization, execution and delivery by each Investor and that this Agreement constitutes the legal, valid and binding agreement of each applicable Investor, shall constitute a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, or other laws of general application relating to or affecting the enforcement of creditors’ rights generally, or (ii) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies. Upon its execution by the Company and the other parties thereto and assuming that it constitutes legal, valid and binding agreements of the other parties thereto, the Registration Rights Agreement will constitute a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws relating to or affecting creditors generally or by general equity principles (regardless of whether such enforceability is considered in a proceeding in equity or at law). Any member of the Board who is an Investor or an Affiliate of an Investor abstained from all votes of the Board (or any committee of the Board) pricing and approving the transactions contemplated by the Transaction Agreements.

3.5 Valid Issuance. The Shares, when issued, sold and delivered to the Investors in accordance with the terms and for the consideration set forth in this Agreement, will be validly issued, fully paid and nonassessable and free of all encumbrances and restrictions on transfer (other than those as provided in the Transaction Agreements or restrictions on transfer under applicable state and federal securities laws). The holder of the Shares shall be entitled to all rights accorded to a holder of Common Stock. Subject to the accuracy of the representations and warranties made by the Investors in Section 4, the offer and sale of the Securities to the Investors is and will be in compliance with applicable exemptions from (i) the registration and prospectus delivery requirements of the Securities Act and (ii) the registration and qualification requirements of applicable securities laws of the states of the United States.

3.6 No Conflict. The execution, delivery and performance of the Transaction Agreements by the Company, the issuance and sale of the Securities and the consummation of the other transactions contemplated by the Transaction Agreements do not and will not (i) conflict with or violate any provision of the Amended and Restated Certificate of Incorporation or Amended and Restated Bylaws, (ii) conflict with or result in a violation of or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation, a change of control right or to a loss of a benefit under any agreement or instrument, credit facility, franchise, license, judgment, order, statute, law, ordinance, rule or regulations, applicable to the Company or any Subsidiary or their respective properties or assets, or (iii) conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or any Subsidiary is subject (including federal and state securities laws and regulations) and the rules and regulations of any self-regulatory organization to which the Company or its securities are subject, or by which any property or asset of the Company or any Subsidiary is bound or affected, except, in the case of clauses (ii) and (iii), as would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect.

3.7 Consents. Assuming the accuracy of the representations and warranties of the Investors in Section 4, no consent, approval, authorization, filing with or order of or registration with, any court or governmental agency or body is required in connection with the authorization, execution or delivery by the Company of the Transaction Agreements, the issuance and sale of the Securities and the performance by the Company of its other obligations under the Transaction Agreements, except such as (a) have been or will be obtained or made under the Securities Act or the Exchange Act, (b) the filing of any requisite notices and/or application(s) to the National Exchange for the issuance and sale of the Shares and the listing of the Shares for trading or quotation, as the case may be, thereon in the time and manner required thereby, (c) customary post-closing filings with the SEC or pursuant to state securities laws in connection with the offer and sale of the Shares by the Company in the manner contemplated herein, which will be filed on a timely basis, (d) the filing of the registration statement required to be filed by the Registration Rights Agreement, or (e) such that the failure of which to obtain would not have a Material Adverse Effect.

No amendment, modification, alteration, or change in any of the terms of this Agreement shall be valid or binding upon the parties hereto unless made in writing and duly executed by the Company and each Investor that, together with its Affiliates (and any other Person that shares the same management company or investment adviser or sub-adviser as such Investor), agrees to purchase at least $20,000,000 of Shares and at least such amount is then held by such Investor and its Affiliates (and any other Person that shares the same management company or investment adviser or sub-adviser as such Investor), provided that prior to the Closing the consent of all Investors shall be required. Notwithstanding the foregoing, this Agreement may not be amended and the observance of any term of this Agreement may not be waived with respect to any Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion. The Company, on the one hand, and each Investor, on the other hand, may by an instrument signed in writing by such parties waive the performance, compliance or satisfaction by such Investor or the Company, respectively, with any term or provision of this Agreement or any condition hereto to be performed, complied with or satisfied by such Investor or the Company, respectively. Notwithstanding the foregoing or anything else herein to the contrary, no amendment, modification, alteration, change or waiver of this Section 8.15 shall be valid without the prior written consent of the Placement Agents, which consent may be granted or withheld in the sole discretion of the Placement Agents. In addition, no consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of this Agreement unless the same consideration (other than the reimbursement of legal fees) also is offered to all Investors.

8.16 Survival. The covenants, representations and warranties made by each party hereto contained in this Agreement shall survive the Closing and the delivery of the Securities in accordance with their respective terms. Each Investor shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

8.17 Contract Interpretation. This Agreement is the joint product of each Investor and the Company and each provision of this Agreement has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto.

8.18 Arm’s Length Negotiations. For the avoidance of doubt, the parties acknowledge and confirm that the terms and conditions of the Securities were determined as a result of arm’s-length negotiations.
