FOR IMMEDIATE RELEASE

Immunovaccine Receives an Extension to the Maturity Date of its $5M Loan Until 2020

Halifax, Nova Scotia; October 17, 2017 – Immunovaccine Inc. (TSX: IMV; OTCQX: IMMVF), a clinical stage immuno-oncology company, today announced that it has received a two-year extension of the maturity of its Province of Nova Scotia loan authorized in 2013. Originally, the maturity date of the loan in the principal amount of $5 million was August 9, 2018. The new maturity date is now August 9, 2020. The annual interest rate remains at the Province’s cost of funds plus 1%.

“Maintaining a strong financial position is a critical step for our organization as we make this important transition into a later-clinical stage life sciences company,” said Pierre Labbé, Chief Financial Officer of Immunovaccine.

“As we approach the anticipated topline data from our Phase 1 clinical trial with Incyte Corporation, and several additional near-term milestones for our lead product candidate, DPX-Survivac, the extension of this loan’s maturity date will allow us to maintain a stronger balance sheet,” said Frederic Ors, Chief Executive Officer of Immunovaccine.
