action of the Licensee, the Licensee shall reimburse the Government for any costs, expenses, or fees, which the Government incurs as a result of the motion or other action. Upon the Licensee’s payment of all
costs incurred by the Government as a result of the Licensee’s joinder motion or other action, these actions by the Licensee shall not be considered a default in the performance of any material obligation under this
Agreement. 


  

	12.	 NEGATION OF WARRANTIES AND INDEMNIFICATION 



 

	 	12.1	 The IC offers no warranties other than those specified in Article 1. 



 

	 	12.2	 The IC does not warrant the validity of the Licensed Patent Rights and makes no representations
whatsoever with regard to the scope of the Licensed Patent Rights, or that the Licensed Patent Rights may be exploited without infringing other patents or other intellectual property rights of Third Parties.



  

	 	12.3	 THE IC MAKES NO WARRANTIES, EXPRESSED OR IMPLIED, OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE
OF ANY SUBJECT MATTER DEFINED BY THE CLAIMS OF THE LICENSED PATENT RIGHTS OR TANGIBLE MATERIALS RELATED THERETO. 


  

	 	12.4	 The IC does not represent that it shall commence legal actions against Third Parties infringing
the Licensed Patent Rights. 


  

	 	12.5	 The Licensee shall indemnify and hold the IC, its employees, students, fellows, agents, and
consultants harmless from and against all liability, demands, damages, expenses, and losses, including but not limited to death, personal injury, illness, or property damage in connection with or arising out of: 



 

	 	(a)	 the use by or on behalf of the Licensee, its Sublicensees, its Affiliates, or their
respective directors, employees, or Third Parties (on behalf of the Licensees, its Sublicensees, or Affiliates) of any Licensed Patent Rights; or 



 

	 	(b)	 the design, manufacture, distribution, or use of any Licensed Products, Licensed Processes or
materials, by the Licensee, or other products or processes developed in connection with or arising out of the Licensed Patent Rights. 


  

	 	12.6	 The Licensee agrees to maintain a liability insurance program consistent with sound business practice.

	13.	 TERM, TERMINATION, AND MODIFICATION OF RIGHTS 



 

	 	13.1	 This Agreement is effective when signed by all parties, (the “Effective Date”), and shall extend to
the expiration of the last to expire of (a) the Licensed Patent Rights and (b) the U.S. Orphan Drug Exclusivity, European Orphan Drug Exclusivity, Australian Orphan Drug Exclusivity, Japanese Orphan Drug Exclusivity or equivalent foreign
Orphan Drug Exclusivity with respect to any Licensed Product, unless sooner terminated under Article 6 or 13. 


  

	 	13.2	 In the event that the Licensee is in default in the performance of any material obligations under this
Agreement, including but not limited to the obligations listed in Paragraph 13.5, and if the default has not been remedied within [***] ([***]) days after the date of notice in writing of the default, the IC may terminate this
Agreement by written notice and pursue outstanding royalties owed through procedures provided by the Federal Debt Collection Act. 


  

	 	13.3	 In the event that the Licensee becomes insolvent, files a petition in bankruptcy, has such a petition
filed against it, determines to file a petition in bankruptcy, or receives notice of a Third Party’s intention to file an involuntary petition in bankruptcy, the Licensee shall immediately notify the IC in writing.



  

	 	13.4	 The Licensee shall have a unilateral right to terminate this Agreement in any country or
territory by giving the IC sixty (60) days written notice to that effect. 


  

	 	13.5	 The IC shall specifically have the right to terminate or modify, at its option, this Agreement,
if the IC determines that the Licensee: 


  

	 	(a)	 has willfully made a false statement of, or willfully omitted, a material fact in the license application or in
any report required by this Agreement; 


  

	 	(b)	 has committed a material breach of a covenant or agreement contained in this Agreement;



  

	 	(c)	 is not keeping Licensed Products or Licensed Processes reasonably available to the public after
First Commercial Sale; 


  

	 	(d)	 cannot reasonably satisfy unmet health and safety needs; or 



 

	 	(e)	 cannot reasonably justify a failure to comply with the domestic production requirement of Paragraph 5.2, unless
waived. 


  

	 	13.6	 In making the determination referenced in Paragraph 13.5, the IC shall take into account the normal
course of such commercial development programs conducted with sound and reasonable business practices and judgment and the annual reports submitted by the Licensee under Paragraph 9.2. Prior to invoking termination or modification of this
Agreement under Paragraph 13.5, the IC shall give written notice to the Licensee providing the Licensee specific notice of, and a [***] ([***]) day opportunity to respond to, the IC’s concerns as to the items
referenced in 13.5(a)-13.5(g). If the Licensee fails to alleviate the IC’s concerns as to the items referenced in 13.5(a)-13.5(g) or fails to initiate corrective action to the IC’s satisfaction, the IC may
terminate this Agreement. 


  

	 	13.7	 The IC reserves the right according to 35 U.S.C. §209(d)(3) to terminate or modify this
Agreement if it is determined that the action is necessary to meet the requirements for public use specified by federal regulations issued after the date of the license and these requirements are not reasonably satisfied by the
Licensee.

	 	13.8	 Within [***] ([***]) days of receipt of written notice of the IC’s unilateral decision to modify or
terminate this Agreement, the Licensee may, consistent with the provisions of 37 CFR §404.11, appeal the decision by written submission to the designated the IC official. The decision of the designated IC official
shall be the final agency decision. The Licensee may thereafter exercise any and all administrative or judicial remedies that may be available. 


  

	 	13.9	 Within [***] ([***]) days of expiration or termination of this Agreement under this Article 13, a final
report shall be submitted by the Licensee. Any royalty payments, including those incurred but not yet paid (such as the full minimum annual royalty), and those related to patent expense, due to the IC shall become immediately due and
payable upon termination or expiration. If terminated under this Article 13, Sublicensees may elect to convert their sublicenses to direct licenses with the IC pursuant to Paragraph 4.3. Unless otherwise specifically provided for under
this Agreement, upon termination or expiration of this Agreement, the Licensee shall return all Licensed Products or other materials included within the Licensed Patent Rights to the IC or provide the
IC with written certification of the destruction thereof. The Licensee may not be granted additional the IC licenses if the final reporting requirement is not fulfilled. 



 

	14.	 GENERAL PROVISIONS 



 

	 	14.1	 Neither party may waive or release any of its rights or interests in this Agreement except in writing.
The failure of the Government to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right by the Government or excuse a similar subsequent
failure to perform any of these terms or conditions by the Licensee. 


  

	 	14.2	 This Agreement constitutes the entire agreement between the Parties relating to the subject matter of
the Licensed Patent Rights, Licensed Products and Licensed Processes, and all prior negotiations, representations, agreements, and understandings are merged into, extinguished by, and completely expressed by this
Agreement. 


  

	 	14.3	 The provisions of this Agreement are severable, and in the event that any provision of this
Agreement shall be determined to be invalid or unenforceable under any controlling body of law, this determination shall not in any way affect the validity or enforceability of the remaining provisions of this Agreement.



  

	 	14.4	 If either party desires a modification to this Agreement, the parties shall, upon reasonable notice of
the proposed modification by the party desiring the change, confer in good faith to determine the desirability of the modification. No modification shall be effective until a written amendment is signed by the signatories to this Agreement or
their designees. 


  

	 	14.5	 The construction, validity, performance, and effect of this Agreement shall be governed by Federal law
as applied by the Federal courts in the District of Columbia. 


  

	 	14.6	 All Agreement notices required or permitted by this Agreement shall be given by prepaid, first
class, registered or certified mail or by an express/overnight delivery service provided by a commercial carrier, properly addressed to the other party at the address designated on the Signature Page, or to any other address as may be designated in
writing by such other party. Agreement notices shall be considered timely if such notices are received on or before the established deadline date or sent on or before the deadline date as verifiable by U.S. Postal Service postmark or dated
receipt from a commercial carrier. Parties should request a legibly dated U.S. Postal Service postmark or obtain a dated receipt from a commercial carrier or the U.S. Postal Service. Private metered postmarks shall not be acceptable as proof of
timely mailing.

	 	14.7	 This Agreement shall not be assigned or otherwise transferred (including any transfer by legal process
or by operation of law, and any transfer in bankruptcy or insolvency, or in any other compulsory procedure or order of court) except to a purchaser of all or substantially of the Licensee’s assets or to the Licensee’s
Affiliate(s) without the prior written consent of the IC. The parties agree that the identity of the parties is material to the formation of this Agreement and that the obligations under this Agreement are nondelegable. In
the event that the IC approves a proposed assignment, the Licensee shall pay the IC, as an additional royalty, [***] percent ([***]%) of the fair market value of any consideration received for any assignment of this
Agreement within [***] ([***]) days of the assignment. 


  

	 	14.8	 The Licensee agrees in its use of any IC-supplied
materials to comply with all applicable statutes, regulations, and guidelines, including the NIH and the HHS regulations and guidelines. The Licensee agrees not to use the materials for research involving human subjects or
clinical trials in the United States without complying with 21 CFR Part 50 and 45 CFR Part 46. The Licensee agrees not to use the materials for research involving human subjects or clinical trials outside of the United States without
notifying the IC, in writing, of the research or trials and complying with the applicable regulations of the appropriate national control authorities. Written notification to the IC of research involving human subjects or clinical
trials outside of the United States shall be given no later than [***] ([***]) days prior to commencement of the research or trials. 


  

	 	14.9	 The Licensee acknowledges that it is subject to and agrees to abide by the United States laws and
regulations (including the Export Administration Act of 1979 and Arms Export Control Act) controlling the export of technical data, computer software, laboratory prototypes, biological materials, and other commodities. The transfer of these items
may require a license from the appropriate agency of the Government or written assurances by the Licensee that it shall not export these items to certain foreign countries without prior approval of the agency. The IC neither
represents that a license is or is not required or that, if required, it shall be issued. 


  

	 	14.10	 The Licensee agrees to mark the Licensed Products or their packaging sold in the United States
with all applicable U.S. patent numbers and similarly to indicate “Patent Pending” status. All Licensed Products manufactured in, shipped to, or sold in other countries shall be marked in a manner to preserve the IC patent
rights in those countries. 


  

	 	14.11	 By entering into this Agreement, the IC does not directly or indirectly endorse any product or
service provided, or to be provided, by the Licensee whether directly or indirectly related to this Agreement. The Licensee shall not state or imply that this Agreement is an endorsement by the Government, the
IC, any other Government organizational unit, or any Government employee. Additionally, the Licensee shall not use the names of the IC, NIH, FDA or HHS or the Government or their
employees in any advertising, promotional, or sales literature without the prior written approval of the IC. 


  

	 	14.12	 The Parties agree to attempt to settle amicably any controversy or claim arising under this Agreement or
a breach of this Agreement, except for appeals of modifications or termination decisions provided for in Article 13. The Licensee agrees first to appeal any unsettled claims or controversies to the designated the IC official, or
designee, whose decision shall be considered the final agency decision. Thereafter, the Licensee may exercise any administrative or judicial remedies that may be available. 



 

	 	14.13	 Nothing relating to the grant of a license, nor the grant itself, shall be construed to confer upon any person
any immunity from or defenses under the antitrust laws or from a charge of patent misuse, and the acquisition and use of rights pursuant to 37 CFR Part 404 shall not be immunized from the operation of state or Federal law by reason of the source of
the grant. 


  

	 	14.14	 Paragraphs 8.1, 9.7, 9.8, 12.1-12.5, 13.8, 13.9, 14.12 and 14.14 of
this Agreement shall survive termination of this Agreement.

	 	14.15	 The terms and conditions of this Agreement shall, at the IC’s reasonable discretion, be
considered by the IC to be withdrawn from the Licensee’s consideration and the terms and conditions of this Agreement, and the Agreement itself to be null and void, unless this Agreement is executed by the

Royalties: 
 The Licensee agrees to
pay to the IC a noncreditable, nonrefundable license issue royalty in the amount of Twenty Five Thousand Dollars ($25,000.00) within [***] ([***]) days from the Effective Date of this Agreement. 

The Licensee agrees to pay to the IC a nonrefundable minimum annual royalty in the amount of [***] Dollars ($[***]) as follows:

 The minimum annual royalty payments are due and payable on January 1 of each calendar year and may be credited against any earned
royalties due for sales made in that year. 
 Sublicensing Royalties: 

The Licensee agrees to pay the IC additional sublicensing royalties of: 

[***] percent ([***]%) of any upfront payment in cash or of the fair market value of any upfront non-cash consideration received by the

 Running Royalties on Net Sales: 

The Licensee agrees to pay the IC earned royalties of [***] percent ([***]%) on U.S. based Net Sales by or on behalf of

 If a Priority Review Voucher or a foreign equivalent is granted to the Licensee by
the FDA or another regulatory agency (such as but not limited to the Australian TGA, the EMA or the Japanese Pharmaceuticals and Medical Devices Agency (PMDA)) for a Licensed Product, the Licensee agrees to make one of the following Benchmark
royalty payments for each Priority Review Voucher or foreign equivalent: 
 (1) [***] percent ([***]%) of the transfer or sale price paid or
fair market value of any non-cash consideration by the Third Party to the Licensee or Affiliate for the sold or transferred Priority Review Voucher or a foreign equivalent shall be due and payable to the IC within [***] ([***])
days following Licensee’s receipt of funds from such third-party sale or transfer; or 
 (2) If the Licensee or
Affiliate is granted Priority Review or a foreign equivalent of Licensee’s BLA, NDA, ANDA or other regulatory application by the FDA for a product under the Priority Review Voucher or a foreign equivalent, and
the Licensee or Affiliate uses the Voucher to obtain approval of its own or its Affiliate’s therapeutic for an Orphan Indication or in the Licensed Field of Use, [***] percent ([***]%) of the fair market value shall be due
and payable to the IC within [***] days ([***]) following the grant of the Priority Review by the FDA or its foreign equivalent. 

For the sake of clarity, Licensee shall have no further obligation to pay Benchmark Royalties
after the expiration or termination of this Agreement, and on a per-country basis or per-region basis (e.g., European Union), Net Sales in a particular country or region where there is no valid Licensed Patent
Rights or Orphan Drug Exclusivity shall not contribute to the cumulative Net Sales for purposes of calculating Benchmark Royalties.

 APPENDIX E – COMMERCIAL DEVELOPMENT PLAN 

LB-001 is our lead GeneRide product candidate, which we are developing for the treatment of MMA in patients with the MUT mutation. 

LB-001 consists of a DNA construct including a gene encoding the human MUT enzyme encapsulated in an AAV capsid. The MUT enzyme coding sequence
is coupled to the 2A peptide sequence and surrounded by homology guides that drive the integration of the MUT gene and the 2A peptide sequence into the chromosomal locus for the albumin gene. Based on the way our construct integrates into the
albumin locus, the MUT gene is then expressed resulting in synthesis of MUT enzyme as a separate protein from albumin. We chose LK03, the AAV capsid we use in LB-001, because it has been optimized to target human liver cells. 

In collaboration with our partners at NHI, LogicBio has demonstrated the safety and efficacy of LB-001 in mouse models of MMA, and is planning to submit an
IND for the LB-001 program by the end of 2019. We recently completed a $80M IPO which has provided sufficient funds to progress the LB-001 program to a first in human study in 2020. Assuming successful completion of this study LogicBio will progress
the program to pivotal studies.
