Voluntary Delist from the TSX

Tekmira applied to the Toronto Stock Exchange (“TSX”) in to voluntarily delist its shares from the TSX, which became effective on March 3, 2015. Upon the effective date of delisting, the company's shares are no longer traded on this exchange. Tekmira subsequently became Arbutus Biopharma Inc. (NASDAQ: ABUS).

The Company believes the limited trading volume of its shares on the TSX no longer justifies the expense and administrative complexity of maintaining a dual listing. The company's primary market for its shares will remain the NASDAQ.

No action is required. Tekmira’s common shares which were listed on the TSX are the same shares as those listed on the NASDAQ and you may trade the common shares on the NASDAQ exchange.

Yes, you will retain the same number of shares.

No. Tekmira’s common shares continue to be listed and traded on the NASDAQ under the symbol of “TKMR.”

We understand that most brokers in Canada, including most discount brokers, have the ability to buy and sell securities listed on the NASDAQ.
