5.7          
Compliance with Laws and Other Instruments.  Assuming the truth and accuracy of the representations and warranties of the Lenders set forth in this Agreement, the execution, delivery and performance by the Company of the Transaction Documents and the consummation of the transactions contemplated thereby will not violate (x) the Restated Certificate or the Company’s Bylaws (the “Bylaws”), each as in effect as of the date hereof (y) any material order, writ, injunction, judgment or decree of any governmental authority applicable to the Company (collectively, “Material Decrees”), or (z) any statute, rule or regulation applicable to the Company (collectively, “Applicable Laws”), in each case, except any such violation which could not reasonably be expected to have a Material Adverse Effect.

Disclosure.  The Company has made available to the Lenders all the information reasonably available to the Company that the Lenders have requested for deciding whether to acquire the Notes.  No representation or warranty of the Company contained in this Agreement, as qualified by the Disclosure Schedules, and no certificate furnished or to be furnished to Lenders at the Closing contains any untrue statement of a material fact or, to the Company’s knowledge, omits to state a material fact necessary in order to make the statements contained herein or therein not misleading in light of the circumstances under which they were made.  It is understood that this representation is qualified by the fact that the Company has not delivered to the Lenders, and has not been requested to deliver, a private placement or similar memorandum or any written disclosure of the types of information customarily furnished to purchasers of securities.

6.          Representations and Warranties and Covenants of the Lenders.  Each Lender, severally and not jointly, hereby makes the representations and warranties set forth in this Section 6 below as of the date of this Agreement to the Company and the Placement Agents.

6.1          
Authorization.  This Agreement constitutes such Lender’s valid and legally binding obligation, enforceable in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights and (ii) laws relating to the availability of specific performance, injunctive relief or other equitable remedies.  Each Lender represents that it has full power and authority to enter into this Agreement.

6.2          
Purchase Entirely for Own Account. Each Lender acknowledges that this Agreement is made with Lender in reliance upon such Lender’s representation to the Company that the Securities will be acquired for investment for Lender’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that such Lender has no present intention of selling, granting any participation in, or otherwise distributing the same.  By executing this Agreement, each Lender further represents that such Lender does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to the Securities.

6.3          
Disclosure of Information.  Each Lender acknowledges that it has received all the information it considers necessary or appropriate for deciding whether to acquire the Securities.  Each Lender further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Securities, although nothing set forth herein shall limit the Company’s representations and warranties set forth in Section 5 above nor any Lender’s right to rely thereon.

6.4         
Investment Experience.  Each Lender is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Securities.  If other than an individual, each Lender also represents it has not been organized solely for the purpose of acquiring the Securities.

6.5          
Accredited Investor.  Each Lender is an “accredited investor” within the meaning of Rule 501 of Regulation D of the Securities and Exchange Commission (the “SEC”), as presently in effect. The residency of each Lender is set forth on the Schedule of Lenders hereto.

6.6          
Restricted Securities.  Each Lender understands that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances.  Each Lender represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

14
6.7          
Tax Advisors.   Each Lender has reviewed with its own tax advisors the U.S. federal, state and local and non-U.S. tax consequences of Lender’s purchase of the Securities and the transactions contemplated by this Agreement. With respect to such matters, such Lender relies solely on any such advisor and not on any statements or representations of the Company or any of its agents, written or oral. Such Lender understands that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of the Notes and the transactions contemplated by this Agreement.

6.8          
Further Limitations on Disposition. Without in any way limiting the representations and warranties set forth above, each Lender further agrees not to make any disposition of all or any portion of the Securities unless and until the transferee has agreed in writing for the benefit of the Company to be bound by this Section 6.8 and:

(a)          There is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(b)          (i) Lender has notified the Company of the proposed disposition and has furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition and (ii) if reasonably requested by the Company, Lender shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under federal or state securities laws.  It is agreed that the Company will not require opinions of counsel: (x) for transactions made pursuant to Rule 144 except in extraordinary circumstances, nor (y) for any transfer of the Securities by a Lender that is a partnership, limited liability company or other entity to (A) a partner of such partnership or member of such company, (B) a controlled affiliate of such partnership or company, or (C) a retired partner of such partnership or a retired member of such company who retires after the date hereof; provided that in each of the foregoing cases, the transferee agrees in writing to be subject to the terms of this Section 6.8 to the same extent as if the transferee were an original Lender hereunder.

The provisions of this Section 6.8 shall terminate and be of no further force and effect upon an Initial Public Offering.

6.9          
Market Stand-off. Each Lender hereby agrees that such Lender shall not sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any Common Stock (or other securities) of the Company held by the Lender (other than those included in the registration statement) during the one hundred eighty (180) day period following the effective date of the registration statement for the Company’s Initial Public Offering filed under the Securities Act, provided that all officers and directors of the Company and holders of at least one percent (1%) of the Company’s voting securities are bound by and have entered into similar agreements. The obligations described in this section shall not apply to: (1) a registration relating solely to employee benefit plans on Form S-l or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future, (2) to distributions to current or former partners, members or stockholders of a Lender or to the transfer of any shares owned by a Lender in the Company to its Affiliates or any of the Lender’s stockholders, members, partners or other equity holders; provided that the Affiliate, stockholder member, partner or other equity holder of the Holder agrees to be bound in writing by the restrictions set forth herein, or (3) transactions (including, without limitation, any swap, hedge or similar agreement or arrangement) or announcements, in each case, relating to securities acquired in the IPO (as defined in the Investors’ Rights Agreement) or in open market or other transactions from and after the IPO or that otherwise do not involve or relate to shares of Common Stock owned by a Lender prior to the IPO. The Company may impose stop-transfer instructions and may stamp each certificate with a legend as substantially set forth in Section 6.10 below with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of such one hundred eighty (180) day (or other) period. The Lender agrees to execute a market stand-off agreement with the underwriters in the offering in customary form consistent with the provisions of this section.

15
6.10          
Legends.  It is understood that the Securities may bear the following legends:

“THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT.”

6.11          
Placement Agents. Each Lender hereby acknowledges and agrees that it has independently evaluated the merits of its decision to purchase the Notes, and that (a) the Placement Agents are acting solely as placement agents in connection with the execution, delivery and performance of this Agreement, the Registration Rights Agreement or the Agreement and Plan of Merger, dated as of June 24, 2026, by and among the Company, Passage Bio, Inc. and Peregrine Merger Sub, Inc.

Accordingly, each Lender understands that the offering meets the exemptions from filing under FINRA Rule 5123(b)(1)(C) or (J). Each Lender is an institutional account as defined in FINRA Rule 4512(c).

Notices.  All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified, (ii) when sent by electronic mail if sent during normal business hours of the recipient, if not, then on the next business day, (iii) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid or (iv) one (1) Business Day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written identification of receipt; provided that if the recipient is not located in the United States, two (2) Business Days after deposit with an internationally recognized overnight courier, specifying next day delivery, with written identification of receipt.  All communications shall be sent to a party hereto at the address set forth on the signature page hereto, the Schedule of Lenders, or at such other address or contact information as the Company or Lender may designate by written notice to the other parties hereto by written notice given in accordance with this Section 10.6.

19
10.7          
Delays or Omissions.  No delay or omission to exercise any right, power or remedy accruing to any party upon any breach or default of any other party under this Agreement shall impair any such right, power or remedy of such party, nor shall it be construed to be a waiver of any such breach or default or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring.  Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing or as provided in this Agreement.  All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

10.8          
Entire Agreement; Amendments and Waivers.  This Agreement, the Notes and the other documents delivered pursuant hereto constitute the full and entire understanding and agreement among the parties hereto with regard to the subjects hereof and thereof.  The Company’s agreements with each of the Lenders are separate agreements, and the sales of the Notes to each of the Lenders are separate sales.  Nonetheless, any term of this Agreement and the Notes may be amended or modified and the observance of any term of this Agreement or the Notes may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the Note Holder Majority; provided that:

(a)          in no event may any such amendment or waiver adversely affect any holder of Notes in a manner which is disproportionate to the outstanding principal of the Note held by such holder unless such amendment or waiver is agreed to in writing by such adversely affected holder;

(b)          no amendment may increase the obligation of any Lender to purchase additional Notes or change the principal amount or interest of Notes pursuant to this Agreement without the prior written consent of such Lender;

(c)          Sections 5.20, and 10.20, the definitions in Section 1 of “CFIUS”, “CFIUS-Impacted Lender”, “CFIUS Satisfied Condition”, “CFIUS Filing Requirement”, “DPA”, or this clause (c) of this Section 10.8 with respect to a CFIUS-Impacted Lender may not be amended, modified, terminated or waived without the written consent of such CFIUS-Impacted Lender; and

Any waiver or amendment effected in accordance with this Section shall be binding upon each party hereto and any holder of any Note purchased under this Agreement at the time outstanding and each future holder of all such Notes, as applicable.  No amendment to or waiver of any provision of any Note shall be made unless such amendment or waiver is made with respect to all Notes.

10.9          
Pari Passu Interest.  The Company and the Lenders acknowledge and agree that the payment of all or any portion of the outstanding principal amount of any Note or Prior 2025 Note and all interest thereon shall be pari passu in right of payment and in all other respects, including but not limited to remedies available to Lenders pursuant to Section 7 hereof, the Notes, the Prior 2025 Notes and applicable law.  Upon repayment of any amounts on any Note, the Company shall send along with such repayment an accounting that sets forth the repayments made to all holders of Notes issued hereunder.  In the event a Lender receives payments in excess of its pro rata share of the Company’s payments to the Lenders of all of the Notes and the Prior 2025 Notes, then such Lender shall hold in trust all such excess payments for the benefit of the holders of the other Notes and the Prior 2025 Notes and shall pay such amounts held in trust to such other holders upon demand by such holders.

10.10          
Publicity.  Neither the Company nor any Lender will originate any publicity, news release or other public announcement, written or oral (a “Release”), regarding any Lender’s involvement with the transactions contemplated by this Agreement without the Company and the Lender’s prior written consent, other than (i) the disclosure of this Agreement and the transactions contemplated hereby to potential investors of the Company, or (ii) where such Release is required by applicable law.

20
10.11          
Finder’s Fee.  Each party represents that it neither is nor will be obligated to pay any brokerage or finder’s fee or commissions in connection with this transaction, other than the Company to the Placement Agents pursuant to the amended and restated engagement letter, dated as of June 17, 2026, by and among the Company and the Placement Agents (the “Engagement Letter”).  The Company shall indemnify and hold each of the Lenders harmless, and each Lender shall, severally and not jointly, indemnify and hold the Company harmless, from any liability for any commission or compensation in the nature of a brokerage or finder’s fee (including the costs, expenses, and legal fees of defending against such liability) for which the Company or such Lender, or any of their respective partners, employees or representatives, as the case may be, is responsible.

10.12          
Fees and Expenses. The Company shall pay the fees and expenses of (i) Cooley LLP, counsel for Decheng Capital Global Life Sciences Fund V, L.P. (or its Affiliates), in an amount not to exceed, in the aggregate, $150,000 and (ii) Goodwin Procter LLP, counsel for certain other Lenders, in an amount not to exceed, in the aggregate, $45,000, in each case incurred in connection with both (a) the Notes and (b) the consummation of a PIPE Offering and/or a Non-Traditional IPO, if any.

10.13          
Corporate Securities Law.  THE SALE OF THE SECURITIES THAT ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION FOR SUCH SECURITIES PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE.  THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

10.14          
Aggregation of Rights.  All Notes or shares of Preferred Stock held or acquired by a Lender or its Affiliates shall be aggregated together for the purpose of determining the availability of any rights and imposition of any obligations under this Agreement, and a Lender and its Affiliates may apportion such rights and obligations as among themselves in any manner they deem appropriate.

10.15          
Exculpation Among Lenders.  Each Lender acknowledges that it is not relying upon any person, firm, corporation or stockholder, other than the Company and its officers and directors in their capacities as such, in making its investment or decision to invest in the Company.  Each Lender agrees that no other Lender nor the respective controlling persons, officers, directors, partners, agents, stockholders or employees of any other Lender shall be liable for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase and sale of the Securities.

10.16          
Construction.  The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.  Unless the context of this Agreement otherwise requires, to the extent necessary so that each clause will be given the most reasonable interpretation, the singular number will include the plural and vice versa, the verb will be construed as agreeing with the word so substituted, words importing the masculine gender will include the feminine and neuter genders, words importing persons will include firms and corporations and words importing firms and corporations will include individuals.  As used in this Agreement, the term “or” shall be interpreted to mean “and/or” unless the context of the use plainly means otherwise.  As used in this Agreement, the terms “includes” or “including” shall be interpreted to mean “includes without limitation” or “including, as applicable,” and shall not be interpreted to limit the scope of the provisions directly preceding such terms.

21
10.17          
Counterparts.  This Agreement may be executed in any number of counterparts and signatures may be delivered via electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method, each of which may be executed by less than all parties, each of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute one instrument.

10.18          
Severability.  Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

10.19          
Titles and Subtitles.  The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

10.20          
CFIUS Filing Event. In the event of a CFIUS Filing Requirement, the Company and such Lender shall, and shall cause any Affiliates to, cooperate and promptly make a CFIUS filing in the requested, required or advisable form in accordance with the DPA. For the avoidance of doubt, the Company and a CFIUS-Impacted Lender shall have no obligation to accept or take any action, condition or restriction with respect to the proposed transaction in order to achieve the CFIUS Satisfied Condition.

10.21          
Exculpation and Acknowledgement of Placement Agents. Each party hereto agrees for the express benefit of each of the Placement Agents, its affiliates and its representatives that:

(a)          Each of the Placement Agents is acting solely as financial advisor to the Company in connection with the sale of the Notes and is not acting in any other capacity and is not and shall not be construed as a fiduciary for the Lender, or any other person or entity in connection with the sale of the Notes.

(b)          No Placement Agent or any of its affiliates or any of its representatives (i) shall be liable for any improper payment made in accordance with the information provided by the Company, (ii) has made or will make any representation or warranty, express or implied, of any kind or character, and has not provided any advice or recommendation to the Lenders in connection with the purchase or sale of the Notes, (iii) has any responsibilities as to the validity, accuracy, completeness, value or genuineness, as of any date, of any information, certificates or documentation delivered by or on behalf of the Company pursuant to this Agreement, the Registration Rights Agreement or the Merger Agreement, or in connection with any of the transactions contemplated by such agreements, including any valuation, offering or marketing materials, or any omissions from such materials; or (iv) shall be liable or have any obligation (including, without limitation, for or with respect to any losses, claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements incurred by the Lenders, the Company or any other person or entity), whether in contract, tort or otherwise to the Lenders or to any person claiming through the Lenders, (x) for any action taken, suffered or omitted by any of them in good faith and reasonably believed to be authorized or within the discretion or rights or powers conferred upon it by this Agreement, the Registration Rights Agreement or the Merger Agreement or (y) for anything which any of them may do or refrain from doing in connection with this Agreement, the Registration Rights Agreement or the Merger Agreement, except for such party’s own gross negligence, willful misconduct or bad faith.

(c)          The Placement Agents, their respective affiliates and their respective representatives shall be entitled to rely on, and shall be protected in acting upon, any certificate, instrument, opinion, notice, letter or any other document or security delivered to any of them by or on behalf of the Company.

22
(d)          Each Lender acknowledges that each of the Placement Agents is acting as a placement agent on a “best efforts” basis for the Notes being offered hereby and will be compensated by the Company for acting in such capacity. Each Lender represents that such Lender was contacted regarding the sale of the Notes by a Placement Agent or the Company (or an authorized agent or representative thereof) with whom the Lender entered into a verbal or written confidentiality agreement.

(e)          Each Lender represents that it is making this investment based on the results of its own due diligence investigation of the Company, and has not relied on any information or advice furnished by or on behalf of the Placement Agents in connection with the transactions contemplated hereby. Each Lender acknowledges that none of the Placement Agents have made, and will not make, any representations and warranties with respect to the Company or the transactions contemplated hereby, and such Lender will not rely on any statements made by any of the Placement Agents, orally or in writing, to the contrary.

10.22          
Third-Party Beneficiaries.  Each of the Placement Agents will be entitled to rely, as an express third‑party beneficiary, on the representations and warranties and covenants of the Lenders and the Company set forth in Section 5, Section 6, and Section 10.21 hereof.
