 “(iii) As of the IND Transfer Date, all sponsor’s responsibility for the IND (official FDA contacts,

Att: Mr. [***]
  

Dear [***]:,
	  	  
 






 Intercell AG (“Intercell”) and VaccGen International LLC (“VaccGen”) have entered into that certain
Sublicense Agreement, effective April 14, 2003 (as amended from time to time, the “Sublicense Agreement”), relating to a prophylactic second-generation, purified, inactivated Japanese encephalitis vaccine as further described in the
Sublicense Agreement (the “Vaccine”). 
 Intercell intends to enter into a collaborative development and commercialization arrangement, and certain
related agreements, with Biological E Limited, a company established under the laws of India, currently having a place of business at 18/1&3, Azamabad, Hyderabad—500 020, A.P., India (“BE”) relating to the development,
manufacture, and commercialization of a prophylactic vero cell-derived inactivated Japanese encephalitis vaccine in certain territories (the “Project”). 

1. Intercell and VaccGen hereby acknowledge and agree that, with respect to the Project and all agreements (including sublicenses) relating thereto
(“Project Agreements”), (i) BE shall be deemed to be, and shall be treated as, a “Marketing Partner” (as such term is defined and used in the Sublicense Agreement) for all purposes of the Sublicense Agreement, and
(ii) neither BE nor BE’s or Intercell’s respective resellers, distributors, sublicensees, and other marketing partners or collaborators engaged in the Project, shall be deemed to be, nor be treated as, “Sublicensees” (as
such term is defined and used in the Sublicense Agreement) for any purposes of the Sublicense Agreement. Consequently, no consideration (whether royalties, profit-sharing or revenue-sharing income, license fees, or otherwise) received by Intercell
under Project Agreements or otherwise in connection with the Project shall be deemed to constitute, nor be treated as, “Sublicense Revenue” (as such term is defined and used in the Sublicense Agreement) for any purposes of the Sublicense
Agreement. 
 2. Intercell represents and warrants that the Projects Agreements, including any future amendments, shall be consistent with the terms and
conditions of the Sublicense Agreement. 
 3. Intercell will send VaccGen a copy of all final executed Project Agreements within ten (10) days of
execution of such Project Agreements. Intercell will also send VaccGen all future executed amendments to the Projects Agreements, if any. 
 4. Nothing
herein shall affect Intercell’s obligation to pay “Royalties” (as such term is defined and used in the Sublicense Agreement) under Section 3.3 of the Sublicense Agreement when and if owed pursuant to the terms and conditions of
the Sublicense Agreement as amended pursuant to this letter.

[***] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, IS OMITTED BECAUSE IT IS BOTH (I) NOT MATERIAL AND
(II) CUSTOMARILY AND ACTUALLY TREATED BY THE REGISTRANT AS PRIVATE OR CONFIDENTIAL. 













 5. For the avoidance of doubt, with respect to BE’s activities under the Project and the Project
Agreements, BE shall be deemed a Person acting on behalf of InterCell for purposes of Section 10.1 of the Sublicense Agreement. 
 6. The following
provisions of the Sublicense Agreement are hereby amended as follows: 
 (a) Section 3.3(i) is hereby amended to read in its entirety as
follows: “For Vaccine marketed, sold, and distributed directly by InterCell and/or its Affiliates (other than to or through Marketing Partners) in a country where such sale would infringe a Valid Claim issued in such country absent this

Section 3.3(i) shall continue until the expiration or final determination of invalidity of the last Valid Claim that would be infringed by the sale of the Vaccine in such country, and upon such expiration or final determination of invalidity of
such last Valid Claim, InterCell shall thereafter pay VaccGen a Royalty of [***] percent ([***]%) for a period of seven (7) years from such expiration.” 

(b) Section 3.3(ii) is hereby amended to read in its entirety as follows: “For Vaccine marketed, sold, and distributed by
InterCell’s Marketing Partners in a country where such sale would infringe a Valid Claim issued in such country absent this Agreement, InterCell shall pay VaccGen a Royalty upon commercialization of the Vaccine equal to [***] percent ([***]%)
of applicable Net Sales. InterCell’s obligation to pay such [***] percent ([***]%) Royalty to VaccGen under this Section 3.3(ii) shall continue until the expiration or final determination of invalidity of the last Valid Claim that would be
infringed by the sale of the Vaccine in such country, and upon such expiration or final determination of invalidity of such last Valid Claim, InterCell shall thereafter pay VaccGen a Royalty of [***] percent ([***]%) for a period of seven
(7) years from such expiration.” 
 (c) The following Section 3.3(iv) is hereby added: “During the period set forth in
Section 3.15, for Vaccine marketed, sold, and distributed directly by InterCell and/or its Affiliates (other than to or through Marketing Partners) in a country where such sale does not infringe a Valid Claim issued in such country, InterCell
shall pay VaccGen a Royalty upon commercialization of the Vaccine equal to [***] percent ([***]%) of applicable Net Sales. For the avoidance of doubt, this Section 3.3(iv) only applies with respect to countries where a Valid Claim never existed
at some point in time.” 
 (d) The following Section 3.3(v) is hereby added: “During the period set forth in
Section 3.15, for Vaccine marketed, sold, and distributed by InterCell’s Marketing Partners in a country where such sale does not infringe a Valid Claim issued in such country, InterCell shall pay VaccGen a Royalty upon commercialization
of the Vaccine equal to [***] percent ([***]%) of applicable Net Sales. For the avoidance of doubt, this Section 3.3(v) only applies with respect to countries where a Valid Claim never existed at some point in time.”

(i) The following Section 3.15(i) is hereby added: “InterCell’s obligation to pay Royalties under Sections 3.3(iv) and 3.3(v)
with respect to Net Sales in any particular country shall continue for a period of seven (7) years from the first commercial sale of Vaccine by InterCell or its Marketing Partners in such country. InterCell’s obligation to pay Royalties
under Sections 3.3(i) and 3.3(ii) shall continue as, and only as, provided therein.”

 (ii) The following Section 3.15(ii) is hereby added: “InterCell’s obligation
to pay Royalties and other amounts to VaccGen under Section 3.4 shall continue until the expiration or final determination of invalidity of the last sublicensed Valid Claim, and upon such expiration or final determination of invalidity of the
last sublicensed Valid Claim, InterCell will thereafter pay for a period of seven (7) years a reduced Royalties amount under Section 3.4 of [***].” 

(iii) The following Section 3.15(iii) is hereby added: “Upon expiration of the applicable seven (7) year periods set forth in
Sections 3.3(i) and 3.3(ii) and Sections 3.15(i) and 3.15(ii), InterCell shall have no further obligation to pay any Royalties (with respect to the applicable country) or other amounts pursuant to Article 3. Notwithstanding the above, InterCell
shall be obligated after expiration of the royalty term to pay any Royalty amounts that accrued under Article 3 prior to such expiration.” 
 This
letter, the Sublicense Agreement (as amended), and such other agreements as are referenced in Section 12.1 of the Sublicense Agreement constitute the entire agreement between the parties relating to the subject matter hereof. Except as
