The Reporting Persons acquired their securities in furtherance of the purpose of the Option Agreement, including the Options and Change of Control Rights.

Subject to the Lock-up, the Reporting Persons intend to continue to review their investment in the Issuer on an ongoing basis and, depending on various factors, including, without limitation, the Issuer’s financial position, the price of the Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may, in the future, take such actions with respect to their shares of Common Stock as they deem appropriate, including, without limitation: purchasing additional shares of Common Stock (which may be in connection with a Change of Control); selling shares of Common Stock (including in registered offerings pursuant to the Registration Rights Agreement); taking any other action with respect to the Issuer or any of its securities in any manner permitted by law or with respect to any and all matters referred to in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 6.

Contracts, Arrangements, Understandings or Relationship with Respect to Securities of the Issuer

Option Agreement

On October 21, 2022 (the “Effective Date”), the Issuer and Audentes entered into the Option Agreement.

The Options

Under the Option Agreement, the Issuer granted to Audentes an exclusive option to obtain an exclusive, worldwide, royalty and milestone-bearing right and license (i) to research, develop, make, have made, use, sell, offer for sale, have sold, import, export and otherwise exploit (collectively, “Exploit”) the product known, as of the Effective Date, as TSHA-120 (the “120 GAN Product”) and any backup products with respect thereto for use in the treatment of giant axonal neuropathy (“GAN”) or any other gene therapy product for use in the treatment of GAN that is controlled by the Issuer or any of its affiliates or with respect to which the Issuer or any of its affiliates controls intellectual property rights covering the Exploitation thereof (each, a “GAN Product”) and (ii) under any intellectual property rights controlled by the Issuer or any of its affiliates with respect to such Exploitation (the “GAN Option”). Subject to certain extensions, the GAN Option is exercisable from the Effective Date through a specified period of time following Audentes’ receipt of (i) the formal minutes from the Type B end-of-Phase 2 meeting between the Issuer and the U.S. Food and Drug Administration (“FDA”) in response to the Issuer’s meeting request sent to the FDA on September 19, 2022 for the 120 GAN Product (the “Type B Meeting”), (ii) all written feedback from the FDA with respect to the Type B Meeting, and (iii) all briefing documents sent by the Issuer to the FDA with respect to the Type B Meeting.

Under the Option Agreement, the Issuer also granted to Audentes an exclusive option to obtain an exclusive, worldwide, royalty and milestone-bearing right and license (i) to Exploit any Rett Product (as defined below), and (ii) under any intellectual property rights controlled by the Issuer or any of its affiliates with respect to such Exploitation (the “Rett Option” and together with the GAN Option, each, an “Option”). Subject to certain extensions, the Rett Option is exercisable from the Effective Date through a specified period of time following Audentes’ receipt of (i) certain clinical data from the Issuer’s female pediatric trial and (ii) certain specified data and other information with respect to Rett Products (such period, the “Rett Option Period”) related to (a) the product known, as of the Effective Date, as TSHA-102 (the “102 Rett Product”) and any backup products with respect thereto for use in the treatment of Rett syndrome (“Rett”), and (b) any other gene therapy product for use in the treatment of Rett that is controlled by the Issuer or any of its affiliates or with respect to which the Issuer or any of its affiliates controls intellectual property rights covering the Exploitation thereof (each, a “Rett Product” and, together with GAN Product, the “Products”).

The parties have agreed that, if Audentes exercises an Option, the parties will, for a specified period, negotiate a license agreement in good faith on the terms and conditions outlined in the Option Agreement, including payments by Audentes of a to be determined upfront payment, certain to be determined milestone payments, and certain to be determined royalties on net sales of GAN Products or Rett Products, as applicable.

Monitoring Rights

During specified periods, the Issuer has agreed to (i) (a) deliver to Audentes certain written reports containing summaries of all material research, development, manufacturing and commercialization activities with respect to GAN Products (and provide more prompt notice of any new information related to the 120 GAN Product that is reasonably likely to materially impact the development or commercialization of the 120 GAN Product) and (b) deliver to Audentes certain written reports summarizing the Issuer’s progress with respect to a development plan and budget for the 102 Rett Product, including all material research, development, manufacturing and commercialization activities with respect to Rett Products, as well as the results of any clinical studies or material non-clinical studies (and provide more prompt notice of any new information related to the 102 Rett Product that is reasonably likely to materially impact the development or commercialization of the 102 Rett Product); and (ii) promptly notify Audentes of any meeting with the FDA with respect to the 120 GAN Product or 102 Rett Product. In addition, during specified periods, the Issuer has agreed to meet with Audentes and provide Audentes with additional information, in each case as reasonably requested by Audentes.

Furthermore, the Issuer has agreed to provide to Audentes (i) with respect to the GAN Option, certain diligence information with respect to the 120 GAN Product and certain information and materials relating to the Type B Meeting and (ii) with respect to the Rett Option, certain safety and efficacy data relating to the Female Pediatric Study (as defined in the Option Agreement) and a Rett Data Package (as defined in the Option Agreement) including, among other items, all material data with respect to Rett Products, detailed summaries thereof and information relating to intellectual property rights in Rett Products.

Finally, the Issuer has agreed to use commercially reasonable efforts to complete all activities set forth in a development plan relating to the 102 Rett Product attached to the Option Agreement in accordance therewith, including with a budget set forth therein. Audentes’ prior written consent is required for any material deviation from such development plan.

The rights described in this sub-section, together with the Board Observer right described below, are collectively referred to in this Statement as the “Monitoring Rights.”

Change of Control Rights

During the Rett Option Period, the Issuer has agreed to (i) not solicit or encourage any inquiries, offers or proposals for, or that could reasonably be expected to lead to, a Change of Control, or (ii) otherwise initiate a process for a potential Change of Control, in each case, without first notifying Audentes (a “ROFO Notice”) and offering Audentes the opportunity to submit an offer or proposal to the Issuer for a transaction that would result in a Change of Control. If Audentes fails or declines to submit any such offer within a specified period after the receipt of such ROFO Notice, the Issuer will have the ability to solicit third party bids for a Change of Control transaction. If Audentes delivers an offer to the Issuer for a transaction that would result in a Change of Control, the Issuer and Audentes will attempt to negotiate in good faith the potential terms and conditions for such potential transaction that would result in a Change of Control for a specified period, which period may be shortened or extended by mutual agreement.

In addition, if, during the Rett Option Period, at any time prior to the delivery of a ROFO Notice, the Issuer receives an offer or proposal for a transaction from a third party that would, or could reasonably be expected to, result in a Change of Control, the Issuer must promptly notify Audentes of the offer and, unless contractually prohibited, the terms thereof. If Audentes fails or declines to submit a competing offer within a specified period after the receipt of such notice, the Issuer will have the ability to pursue such third-party offer. However, if, during such pursuit, the terms of such third-party offer materially change, the Issuer must notify Audentes of such materially changed third-party offer and allow Audentes an additional specified period to consider such materially changed third-party offer.

During the Rett Option Period, the Issuer may not enter into (i) any letter of intent, agreement, contract or commitment (whether or not binding) with respect to a Change of Control or (ii) any agreement, contract or commitment that could impede the ability of Audentes to effect a Change of Control (a “Competing Instrument”), unless the Issuer promptly notifies Audentes at least five business days before entering into a Competing Instrument (which notice must include the terms thereof, unless the Issuer is contractually prohibited from disclosing them).

“Change of Control” is defined in the Option Agreement as (i) a consolidation, business combination, merger or similar transaction of the Issuer or any subsidiary with or into any other corporation or other entity or Person, or any other corporate reorganization; (ii) any transaction or series of related transactions in which 50% or more of the Issuer’s voting power is transferred or becomes beneficially owned by any person or group; or (iii) the sale or transfer of all or substantially all of the Issuer’s assets or any asset that is material to the Issuer and its subsidiaries, taken as a whole, or the exclusive license of substantially all of the Issuer’s intellectual property that is material to the Issuer and its subsidiaries, taken as a whole.

The rights described in this sub-section are collectively referred to in this Statement as the “Change of Control Rights.”

Consideration

As partial consideration for the rights granted to Audentes under the Option Agreement, Audentes will pay the Issuer a one-time payment in the amount of $20.0 million (the “Upfront Payment”) within 30 days after receipt of an invoice for such payment, which invoice will be delivered by the Issuer on or after the Effective Date. Audentes or any of its affiliates have the right, in its or their discretion and upon written notice to the Issuer, to offset the amount of the Upfront Payment (in whole or in part, until the full amount of the Upfront Payment has been offset) against (i) any payment(s) owed to the Issuer or any of its affiliates (or to any third party on behalf of the Issuer) under or in connection with any license agreement entered into with respect to any GAN Product or Rett Product, including, any upfront payment, milestone payment or royalties owed to the Issuer or any of its affiliates (or to any third party on behalf of the Issuer) under or in connection with any such license agreement or (ii) any amount owed to the Issuer or any of its affiliates in connection with a Change of Control transaction with Audentes or any of its affiliates. As further consideration for the rights granted to Audentes under the Option Agreement, the Issuer and Audentes also entered into the Securities Purchase Agreement.

The foregoing description of the Option Agreement does not purport to be complete and is qualified in its entirety by reference to such agreement, a copy of which is attached hereto as Exhibit 7 and incorporated into this Item 6 by reference.

Securities Purchase Agreement

On October 21, 2022, the Issuer and Audentes entered into the Securities Purchase Agreement, pursuant to which the Issuer agreed to issue and sell to Audentes in a private placement an aggregate of 7,266,342 shares of Common Stock of the Issuer (the “Shares”), for aggregate gross proceeds of approximately $30.0 million. The transaction closed on October 24, 2022 (the “Closing Date”). The Securities Purchase Agreement contains customary representation s, warranties and agreements by the Issuer, customary conditions to closing, indemnification obligations of the Issuer, other obligations of the parties and termination provisions.

Pursuant to the Securities Purchase Agreement, the Purchaser may not, without the prior written consent of the Issuer, during the period commencing on the Closing Date and ending on the date that is 180 days after the Closing Date (i) lend, 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, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock; or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any shares of Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise (the “Lock-up”). The Lock-up is subject to certain limited exceptions, including the ability to transfer shares to Audentes’ affiliates and certain related persons; provided the transferee agrees to be bound by such restrictions.

Pursuant to the Securities Purchase Agreement, Audentes has the right, effective as of the Closing Date, to designate one individual to attend all meetings of the board of directors in a non-voting observer capacity (the “Board Observer”). The Board Observer is entitled to all notices, minutes, consents and other materials provided to the Issuer’s directors at the same time and in the same manner as provided to such directors. The Board Observer right terminates upon a Change of Control (as defined in the Securities Purchase Agreement) or when Audentes no longer holds shares of Common Stock.

The foregoing description of the Securities Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to such agreement, a copy of which is attached hereto as Exhibit 5 and incorporated into this Item 6 by reference.

Registration Rights Agreement

On October 21, 2022, the Issuer and Audentes entered into a registration rights agreement, attached hereto as Exhibit 6 (the “Registration Rights Agreement”), pursuant to which the Issuer agreed to register the resale of the Shares. Under the Registration Rights Agreement, the Issuer has agreed to file a registration statement covering the resale of the Shares no later than April 24, 2023 (the “Filing Deadline”). The Issuer has agreed to use reasonable

best efforts to cause such registration statement to become effective as promptly as practicable after the filing thereof but in any event on or prior to the Effectiveness Deadline (as defined in the Registration Rights Agreement), and to keep such registration statement continuously effective until the earlier of (i) the date the Shares covered by such registration statement have been sold or may be resold pursuant to Rule 144 without restriction, or (ii) the date that is three (3) years following the Closing Date. The Issuer has also agreed, among other things, to pay all reasonable fees and expenses (excluding any underwriters’ discounts and commissions and all fees and expenses of legal counsel, accountants and other advisors for Audentes except as specifically provided in the Registration Rights Agreement) incident to the performance of or compliance with the Registration Rights Agreement by the Issuer.

The Issuer and Audentes granted each other customary indemnification rights in connection with the registration statement. The Issuer made additional customary covenants, including with respect to “piggyback” registrations, cooperating in underwritten offerings of the Shares and taking steps to allow the Shares to be resold pursuant to Rule 144 under the Securities Act of 1933.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to such agreement, a copy of which is attached hereto as Exhibit 6 and incorporated into this Item 6 by reference.
