Re: Material Transfer and Research Agreement with RPCI

Dear Mr. Equels:

Enclosed is a fully executed original of the Material Transfer And Research Agreement between Hemispherx Biopharma, Inc. and Roswell Park Cancer Institute, effective July 11, 2017. You will note that you executed it on July 11, 2017 and it was countersigned by Dr. Victor A. Filadora, Chief of Clinical Services on July 14, 201 7. This document replaces the Material Transfer And Research Agreement that you signed on July 11, 2017, which was countersigned by Dr. Thomas Schwaab, Chief of Strategy, Outreach and Business development on July 11, 2017. That document should be destroyed to avoid confusion. As we discussed the Agreement that was countersigned by Dr. Schwaab included minor redline changes that are apparent on the signature page. The redlines were simply accepted by Roswell so that there is a clean Agreement. A comparison of the two documents will show that no substantive changes were made, but Roswell preferred to have a clean document. Thank you for accommodating this request and apologies for the inconvenience.

Very truly yours,
Elizabeth A.Ollinick
