	 	(a)	 subject to Section 3.5, a per-unit (i.e., Distributed Dose)
royalty (quota license) in an amount of [***] per Distributed Dose (the “Running Royalty”); and 


  

	 	(b)	 subject to Section 3.6, an annual fixed license fee of [***] per Calendar Year (the “Annual
Minimum Royalty”). 


 The Running Royalty and the Annual Minimum Royalty shall be reduced by [***]. 

Debtor of any royalties payable to Wacker Biotech according to this Section 3.1 shall be PhaseBio, irrespective of whether or not the
royalties payable to Wacker Biotech result from actions subject to licenses of PhaseBio, its Affiliates or its Sublicensee(s); royalties payable to Wacker Biotech under this Section 3.1 shall be made by PhaseBio as if any action subject to
licenses has been made by PhaseBio directly. 
  

	3.2	 The amount of [***] per Distributed Dose pursuant to Section 3.1(a) shall be valid until and including the
calendar year [***]. For the period following the calendar year [***] the per-unit royalty pursuant to Section 3.1(a) shall [***], without further declarations or agreements between the Parties being
required. For the avoidance of doubt, for the year [***] the amount of [***] per Distributed Dose pursuant to Section 3.1(a) shall [***]. Notwithstanding the foregoing, but always subject to Section 3.3, beginning with [***], in no event
shall the per-unit royalty under Section 3.1(a) [***] the per-unit royalty under Section 3.1(a) for [***] by reason of any and all [***] for the [***],
regardless of the [***], without the prior written consent of PhaseBio; provided, however, that in the event of [***] that Wacker Biotech believes in good faith [***], Wacker Biotech and PhaseBio shall negotiate in good faith [***].



  

	3.3	 As of the Effective Date the Parties assume that the amount of Product in a Dose will be [***]. The Parties
hereby agree that in case the the amount of Product in a Dose will exceed [***] the Parties will enter into good faith negotiations on [***] to adequately reflect the [***]. 



 

	3.4	 If PhaseBio reasonably determines that it is necessary for the execution of the rights granted under Sections
2.1 and 2.2 [***], the royalties payable to Wacker Biotech under Section 3.1 shall be [***]; provided, however, that in no event shall any royalties payable to Wacker Biotech [***] pursuant to this Section 3.4 [***] of the royalties
payable to Wacker Biotech in Section 3.1 above.

	3.5	 For the avoidance of doubt, there are no Running Royalties due or payable for that share of the Distributed
Doses containing solely Product manufactured by Wacker Biotech under a separate supply agreement to be conducted by the Parties. 



Furthermore PhaseBio, its Affiliate or its Sublicensee(s) collectively will be allowed to distribute Doses as free promotional samples up to a
cumulative total of [***] of all Distributed Doses per Calendar Year (“Promotional Samples”). Any Promotional Samples that have been made available to an independent Third Party up to such percentage in a Calendar Year shall be
deemed not to be Distributed Doses and shall not be subject to the obligation to pay Running Royalties. Any Doses which have been made available as free promotional samples to an independent Third Party exceeding such percentage in a Calendar Year
shall be deemed to be Distributed Doses and shall be subject to the obligation to pay Running Royalties. 
  

	3.6	 The Running Royalty of a Calendar Year – if any – shall be fully creditable against the Annual
Minimum Royalty of the same Calendar Year. 


 The Annual Minimum Royalty shall be due beginning with such Calendar Year in
which the Developed Strain was transferred to PhaseBio by Wacker Biotech and shall be payable within [***] days of the beginning of a Calendar Year. In the event the First Calendar Year is not a Full Calendar Year the Annual Minimum Royalty for such
First Calendar Year shall be paid on a pro rata basis calculated on the basis of 365 calendar days per Calendar Year and shall be due and payable within [***] days after the Effective Date. For each Calendar Year following the First Calendar
Year the Annual Minimum Royalty shall be due within [***] days of the beginning of such Calendar Year. In the event the Last Calendar Year is not a Full Calendar Year the Annual Minimum Royalty for such Calendar Year shall be paid on a pro rata
basis calculated on the basis of 365 calendar days per Calendar Year; in case of any excess payment Wacker Biotech shall reimburse PhaseBio any amount paid in excess within [***] after the later of (i) the termination date of this Agreement or
(ii) the date on which an excess payment has been determined. 
  

	3.7	 Within [***] days after June 30 and December 31 of each Calendar Year (semi-annually), PhaseBio shall
furnish to Wacker Biotech a written report showing in reasonably specific detail 


  

	 	(a)	 the amount of Distributed Doses for the preceding six (6) months period; and 



 

	 	(b)	 the calculation of the payments due and payable, if any, which shall have accrued hereunder; and



  

	 	(c)	 withholding taxes, if any, required by law to be deducted in respect of any royalties due.



 In the report of December 31 of each Calendar Year PhaseBio shall include additionally the amount and percentage
(in relation to the amount of Distributed Doses) of Promotional Samples for the preceding twelve (12) months period. 
 In case no
Running Royalties have become due in a reporting period PhaseBio shall inform Wacker Biotech accordingly at the due dates according to the foregoing stipulations. 
  

	3.8	 The Running Royalty shall be payable on the day the written report according to Section 3.7 is due.



  

	3.9	 Any payments due to Wacker Biotech hereunder shall be a net payment, i.e. free of any bank and transfer charges
and without deduction of any Taxes (including Indirect Taxes) or other fees payable outside the Federal Republic of Germany, except any withholding tax, if any, imposed on the amount payable under this Agreement which PhaseBio may deduct from
payment hereunder and pay to the relevant Tax Authority. In the event withholding taxes shall be due the Parties will reasonably cooperate in completing and filing a request for exemption or reduction of withholding tax required under the provisions
of any applicable double taxation or similar treaty or agreement in order to enable PhaseBio to make such payments to Wacker Biotech under this Agreement without any deduction or with reduced withholding. PhaseBio will furnish Wacker Biotech with
the certificate of tax receipt issued by the relevant tax office, necessary to have such taxes credited in the Federal Republic of Germany. 



  
 - 10 - 














	3.10	 All payments hereunder shall be payable in Euro (EUR) and shall be submitted by PhaseBio to Wacker Biotech to
the following account of Wacker Biotech GmbH with Deutsche Bank, München (unless Wacker Biotech informs PhaseBio in writing about a change in the receiving bank): 



[***] 
 adding the remark [***].

 The obligation to pay shall only be considered fulfilled on the day on which the complete amount of money is credited to said account.

  

	3.11	 Whenever conversion of United States Dollars (USD) to Euro (EUR) shall be required, such conversion shall be
calculated using the exchange rates of the European Central Bank (“ECB”) (e.g., https://www.ecb.europa.eu; also available at Reuters page “ECB37”). For the purposes of crediting the Running Royalty of a Calendar Year against the
Annual Minimum Royalty of the same Calendar Year the following procedure shall apply: For calculation purposes the Annual Minimum Royalty shall be converted to United States Dollars (USD) on the day on which the respective Annual Minimum Royalty is
due using the exchange rate of the ECB of that day; any balance to be paid by PhaseBio between the respective converted Annual Minimum Royalty in United States Dollars (USD) and the credited Running Royalties of the same Calendar Year shall be
converted from United States Dollars (USD) to Euro (EUR) using the average exchange rate of the ECB published for the respective six (6) month royalty period during the Calendar Year. 



 

	3.12	 In the event that PhaseBio is delinquent in the payment due under this Agreement, Wacker Biotech is entitled to
charge default interest amounting to [***] above the interest rate of the European Central Bank (ECB). Such interest shall be calculated on a pro rata basis from the day payment was due until the day the payment is credited to the account according
to Section 3.10. 


  

	3.13	 PhaseBio will keep complete and accurate records of account for [***] years preceding the current year for the
verification of the royalties to be paid under this Agreement. During the term of this Agreement and within [***] years after termination, such records of account shall be open at all reasonable times – but not more than once each calendar year
- to the inspection of an independent certified auditor chosen by Wacker Biotech and acceptable to PhaseBio. The auditor shall keep confidential any information obtained during such inspection and shall report to Wacker Biotech only the payments due
and payable. 


 The costs of such inspection and audit shall be borne by Wacker Biotech, unless it shall be established by
Wacker Biotech that as a result of an error in such a report PhaseBio has failed to pay Wacker Biotech at least [***] of the full amount of royalties due and owing under this Agreement, in which event the costs of such inspection shall be borne by
PhaseBio. The results of such inspection are binding to the Parties. 
  

	3.14	 Subject to Section 3.6, last sentence any payments already made by PhaseBio are not refundable in any
event, including termination of this Agreement. 


  

	4.	 Confidentiality and Use Restrictions 



 

	4.1	 Unless otherwise agreed in this Agreement, the Receiving Party shall keep strictly confidential any
Confidential Information of the Disclosing Party and shall not make Confidential Information of the Disclosing Party, in whole or in part, available to any Third Party (including any patent offices or similar authorities). The Receiving Party shall
use Confidential Information of the Disclosing Party only for the purpose of exercising its rights (including, in the case of PhaseBio as the Receiving Party, the rights granted hereunder under Section 2.1 and 2.2) and performing its
obligations under this Agreement. The Receiving Party shall not use or exploit Confidential Information of the Disclosing Party in any form directly or indirectly, in whole or in part, for any other purposes or for the obtainment of intellectual
property rights. All Confidential Information of the Disclosing Party and all rights therein shall remain the Disclosing Party’s exclusive property. 



In particular PhaseBio shall not deposit, in whole or in part, the Developed Strain with a depositary institution [***];
furthermore PhaseBio shall use the Developed Strain only for the purpose of exercising its rights under this Agreement. 

  
 - 11 - 














	4.2	 The Receiving Party shall take all necessary steps to meet the obligations set forth in this Article 4. The
Receiving Party shall disclose Confidential Information of the Disclosing Party only to those of its directors, officers, employees, legal representatives, Sublicensee(s) or contract manufacturers (the “Permitted Persons”) who have
a need to know of such Confidential Information for the exercise of the Receiving Party’s rights (including, in the case of PhaseBio as the Receiving Party, the rights granted hereunder under Section 2.1 and 2.2) and the performance of the
Receiving Party’s obligations hereunder and who have agreed before to be bound by the terms of confidentiality and restricted use consistent with this Agreement, in particular this Article 4, in writing, unless such Permitted Persons are
already bound accordingly by the terms of employment, other contracts or by applicable law. The Receiving Party shall be liable for any breach of the provisions of this Agreement by its Permitted Persons. 



However, notwithstanding the foregoing PhaseBio shall not disclose or make otherwise available to any Third Party, expressly
not to Sublicensee(s) or contract manufacturers, the genotype and/or related genetic information of the Wacker Secretion Strain and/or the Developed Strain, [***]. 

 

	4.3	 PhaseBio shall not analyze, have analyzed, perform or have performed any reverse engineering or
decompilation of the Developed Strain or any other Deliverable provided hereunder in order to receive any information on the genotype and/or related genetic information of the Wacker Secretion Strain (which builds also the basis of the Developed

PhaseBio shall expressly instruct in writing any individual within its organization who has access to the Developed Strain to comply with this non-analysis obligation pursuant to this Section 4.3 and oblige the Permitted Entities in writing to impose a similar obligation to those individuals within the Permitted Entities’ organizations; for
clarity, every individual within PhaseBio’s organization or within the organization of the Permitted Entities who has access to the Developed Strain shall have been expressly instructed in writing to comply with this non-analysis obligation pursuant to this Section 4.3. 
 Furthermore PhaseBio shall not
have the right to reconstruct the Developed Strain. 
  

	4.4	 Subject to (i) the use of Confidential Information reasonably necessary solely for the duration and the
performance of PhaseBio’s rights according to Section 9.9; and/or (ii) the requirement to retain any Confidential Information for regulatory reasons, in the event of termination of this Agreement PhaseBio shall immediately return or
destroy all embodiments of the received Confidential Information, including but not limited to records, data media, product samples, materials or other documents in any form, including any electronic (with respect to electronic files, deleted to the

After termination of this Agreement, PhaseBio shall immediately stop using the WACKER Licensed Technology, in particular the Developed Process
and the Developed Strain and, subject to Section 9.9, any material, including Product, produced by such use; in particular PhaseBio shall immediately destroy the Developed Strain and any modification, derivative, mutations, clones or progeny
thereof. 
 Complete return or destruction shall be confirmed in writing by PhaseBio. The above shall not apply to back-up copies of electronic data routinely prepared but only for the time for which such back-up copies of similar-type information are customarily retained. 

For the sake of clarity, in the event of termination of this Agreement (but not expiration of the Royalty Period), upon expiration of the
period of use permitted under Section 9.9, the obligations of this Section 4.4 on complete return and destruction shall apply without limitation or restriction. 
  

	4.5	 Notwithstanding the obligations of this Article 4, PhaseBio may disclose Confidential Information if it is
required to do so in response to a valid order of a competent court or other government authority; provided however, Confidential Information shall not be disclosed without (a) first timely notifying Wacker Biotech in writing to allow Wacker
Biotech to safeguard its rights by protective order or equivalent; and (b) cooperating with Wacker Biotech to limit the scope of Confidential

law; and (ii) used solely for the purposes for which the order was issued. 

 Notwithstanding the foregoing, Wacker
Biotech acknowledges that PhaseBio intends to establish a contract manufacturing relationship for Product with a contract manufacturer located in [***]. PhaseBio will reimburse Wacker Biotech for (i) all reasonable and documented costs and
expenses of said third party consultant as well as (ii) all reasonable internal efforts and documented out-of-pocket expenses incurred by Wacker Biotech directly in
course of its supporting efforts at the then effective hourly rate of Wacker Biotech. PhaseBio will be invoiced by Wacker Biotech and the payments are due and payable within thirty (30) days net from the date of an invoice. Wacker Biotech is
entitled to charge default interest in accordance with Section 3.12 in the event of delinquency of payment of such invoiced amounts by PhaseBio. 

[***] 
  

	4.6	 PhaseBio agrees and acknowledges that Wacker Biotech or Wacker AG shall have the right once in any calendar
year to seek a legally binding written declaration by PhaseBio and each of its Affiliates, Sublicensees, and contract manufacturers of Product that have access to the Developed Strain (collectively, “Permitted Entities”) that the
WACKER Licensed Technology or any part of it, in particular the Developed Strain, has only been used for the performance of the rights granted hereunder and/or that products, other than Product, Drug Product and/or Final Drug Product, manufactured
or sold by PhaseBio, its Affiliates, its permitted Sublicensee(s) and subcontractors are not made, based upon or using the WACKER Licensed Technology, in particular not ESETEC® and/or the
Wacker Secretion Strain. 


 From time to time upon Wacker Biotech’s request, PhaseBio will provide Wacker Biotech with
a list of the Permitted Entities who have access to the Developed Strain, the WACKER Licensed Technology or any part of it. 
 Furthermore
Wacker Biotech and/or Wacker AG shall have the right at any time, at its own cost, to have an independent expert, acceptable to PhaseBio, investigate to verify that neither PhaseBio, nor the Permitted Entities have in any manner become involved,
directly or indirectly, in the manufacture or sale of a product, other than the Product, Drug Product or Final Drug Product, based upon or using the WACKER Licensed Technology, in particular
ESETEC® and/or the Wacker Secretion Strain (collectively hereinafter a “Misuse of WACKER Licensed Technology”), and such investigation shall [***]. PhaseBio shall cooperate in a
reasonable manner with such independent expert in its investigation. The right of investigation under this sub-paragraph shall be strictly limited to the respective product in question. 

In connection with this investigation, the independent expert shall only provide to Wacker Biotech and/or Wacker AG a report that [***] (the
“Expert’s Statement”). [***] Wacker Biotech and/or Wacker AG shall have the right to use the redacted Expert’s Statement as it deems fit. 

Wacker Biotech and/or Wacker AG’s rights of investigation under this Section 4.6 shall not obligate PhaseBio or any Permitted Entity
to provide [***]. 
 PhaseBio shall require any of its Permitted Entities who will have access to the Developed Strain in writing to
expressly agree to Wacker Biotech and/or Wacker AG’s rights of investigation according to this Section 4.6 prior to any transfer of WACKER Licensed Technology, in particular the Developed Strain, to such Permitted Entities. 

In each event the provisions of this Section 4.6 shall survive [***] after any termination or expiration of this Agreement. Upon
expiration of said [***] term Wacker Biotech and/or Wacker AG shall [***].

foregoing exceptions merely because individual features are within an exception unless the actual combination itself is within an exception. Any specific Confidential Information shall not be deemed to be in the foregoing exceptions merely because
it is encompassed by more general information which is within an exception unless the specific Confidential Information itself is within an exception. 
  

	4.8	 Without limiting the Parties’ rights according to Sections 2.2, 6.2 and 10.8, each Party shall keep

and all losses, damages, costs and expenses, including reasonable attorneys’ fees and court costs (hereinafter collectively “Damages”), to which any Wacker Biotech Released Party may become subject as a result of any claim,
demand, action or other proceeding by any Third Party (each, an “Action”), to the extent such Damages result from or arise out of (i) any breach by PhaseBio of any of its warranties or representations set forth in
Section 7.1; (ii) any product liability claims with respect to Product, Drug Product and/or Final Drug Product made by or on behalf of PhaseBio or any of its Affiliates or Sublicensees by exercising the license granted hereunder; (iii) an
alleged or actual failure of Product, Drug Product and/or Final Drug Product made by or on behalf of PhaseBio or any of its Affiliates or Sublicensees by exercising the license granted hereunder to conform to requirements of any applicable laws
and/or any applicable regulatory approvals, including the failure of PhaseBio to obtain the necessary regulatory approvals; (iv) the use of any Deliverables, the WACKER Licensed Technology or any other information or material disclosed,
delivered or provided hereunder [***]; and/or (v) [***]. 


 Such indemnification (as described herein under (i) - (v)),
shall not apply if such Action or Damage arises from matters which are subject to Wacker Biotech’s indemnification obligations set forth in Section 8.2. Subject to Section 8.4, PhaseBio will defend any Actions covered by this

all Damages to which any PhaseBio Released Party may become subject as a result of any Action, to the extent such Damages result from or arise out of any breach by Wacker Biotech of any of its warranties or representations set forth in
Section 7.2. 


 Such indemnification shall not apply if and to the extent any Action or Damage arises from matters
which are subject to PhaseBio’s indemnification obligations set forth in Section 8.1.

	8.4	 A Party wishing to seek indemnification hereunder (the “Indemnified Party”) shall notify the
other Party (the “Indemnifying Party”) in writing of any Action as soon as reasonably practicable (“Claim Notice”) after the Indemnified Party receives notice of the Action, shall permit the Indemnifying Party to
assume direction and control of the defense of the Action (including the right to settle the Action solely for monetary consideration) using counsel reasonably satisfactory to the Indemnified Party, and shall cooperate as requested by the
Indemnifying Party’s request (at the Indemnifying Party’s expense), in the defense of such Action. The Indemnifying Party shall keep the Indemnified Party informed on a current basis of its defense of any such Action. Each Party hereto
shall cooperate with the other Party in every reasonable way to facilitate the defence of any such Action. The Indemnified Party shall not agree to any settlement of such Action without the prior written consent of the Indemnifying Party, which

settlement of such Action or consent to any judgment in respect thereof that (i) does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto; (ii) adversely affects the rights of
the Indemnified Party; (iii) admits or imposes any liability or obligation on the Indemnified Party; or (iv) acknowledges fault by the Indemnified Party without the prior written consent of the Indemnified Party. 



The Indemnified Party’s failure to provide a Claim Notice to the Indemnifying Party under this Section 8.4 does not relieve the
Indemnifying Party of any liability that the Indemnifying Party may have to an Indemnified Party, but in no event shall the Indemnifying Party be liable for any Damages that result from a delay in providing a Claim Notice. Each Claim Notice must
contain a description of the Action and the nature and amount of the related Damages (to the extent that the nature and amount of the Damages are known at that time). In the event that a final judgment or order is entered by any court or other
tribunal against the Indemnified Party, the Indemnifying Party shall satisfy such judgment or order (and/or reimburse the Indemnified Party for any amounts it pays against such judgment or order) incurred by the Indemnified Party with regard to its
defence against the Action or Damage within [***] days of the Indemnified Party providing notice to the Indemnifying Party of the judgment or order. 
  

	8.5	 Except for [***], as far as legally permitted neither Party shall be liable to the other Party, whether in
tort, contract or otherwise, for any consequential, special, incidental, punitive or indirect damages, loss or expenses (including but not limited to business interruption, lost business, lost profits, or lost savings) in connection with this
Agreement; provided, however, that this Section 8.5 [***], as applicable. 


  

	8.6	 Except for [***], as far as legally permitted the entire liability of Wacker Biotech to PhaseBio under this
Agreement, whether in tort, contract, under the indemnity contained in Section 8.2 or otherwise shall be limited to [***]. 


  

	8.7	 Nothing in this Agreement shall purport or attempt or serve to exclude or restrict any liability (i) for
any fraud or fraudulent misrepresentation, (ii) for wilful misconduct or (iii) under mandatory applicable law, including without limitation mandatory product liability law. 



 

	8.8	 PhaseBio and Wacker Biotech shall obtain and/or maintain during the term of this Agreement and for a period of
[***] years thereafter, liability insurance in amounts which are reasonable and customary in the biopharmaceutical industry for the respective activities (i.e. Wacker Biotech as contract manufacturing organisation and PhaseBio as
sponsor/pharmaceutical company) at the respective place of business, but no less than [***], and such liability insurance shall insure against all mandatory liability, including liability for personal injury, physical injury and property damage.
Wacker Biotech shall have the right to self-insure at any time.

	9.8	 Furthermore termination of this Agreement or expiration of the Royalty Period for any reason shall not affect
and shall be without prejudice to any rights or obligations of either Party which shall have arisen on or before the date of such termination of this Agreement or expiration of the Royalty Period, nor shall it affect the survival of any provisions
of this Agreement which are expressly, or by implication, intended to survive the termination of this Agreement or expiration of the Royalty Period, in particular without limitation the rights and obligations of Articles 3, 4, 6, 7, 10 and 11 shall
survive any termination of this Agreement or expiration of the Royalty Period (provided that PhaseBio shall have no obligation to pay Running Royalties or any Annual Minimum Royalty for any period after expiration of the Royalty Period. Termination
of the Agreement or expiration of the Royalty Period in accordance with the provisions hereof shall not limit any remedies which may be otherwise available.
