ITEM 6 – APPROVAL OF THE ENGAGEMENT WITH DR. DALIA MEGIDDO

Dr. Dalia Megiddo has been providing services relating to the Company’s intellectual property and relevant patent filings, where she was reporting to the Chief Executive Officer of the Company (the “Services”).

Dr. Megiddo, a member of the Board of Directors, has not received any remuneration for the Services, and the parties agreed that a one time payment of $50,000 plus VAT is appropriate and reasonable under the circumstances, and that receiving the Services from another service provider, at a similar professional level would likely cost the Company more than $50,000.

The Board of Directors and the Compensation Committee concluded that the terms of compensation of Dr. Megiddo exceed the limitations set forth under the Policy. However, after taking into consideration Dr. Megiddo’s experience and deep knowledge of the Company’s patents and other intellectual property rights that it is in the best interest of the Company to have received the Services from Dr. Megiddo and continue to receive them as appropriate.

It is proposed that the following resolution be adopted at the Meeting:

“RESOLVED, to approve the engagement with Dr. Megiddo under the terms set above, and one-time payment of $50,000 plus VAT for such Services, which amount exceeds the limitation set forth in the Policy, as such engagement is necessary under the circumstances, is beneficial to the Company compared to the alternatives and as a whole is in the Company’s best interest.”

Since the terms of compensation of Dr. Megiddo exceed the limitations in the Policy, the affirmative vote of a majority of the shares voting on the matter is required to approve this resolution, providing either (i) included in such majority is at least a majority of the shares of shareholders who are non-controlling shareholders and do not have a personal interest in the said resolution (excluding for such purpose any abstentions disinterested majority); or (ii) the total number of shares of shareholders specified in clause (i) who voted against this resolution does not exceed two percent (2%) of the voting rights in the Company².

The Company’s Board of Directors unanimously recommends that you vote “FOR” the proposal included in this Item.

² In connection with your vote, you are asked to indicate on the enclosed proxy card whether you are a controlling shareholder or have a personal interest in the resolutions (excluding a personal interest that is not related to a relationship with a controlling shareholder). Under the Companies Law, in general, a person will be deemed to be a controlling shareholder if the person has the power to direct the activities of the company, other than by reason of being a director or other office holder of the company. A person holding 25% of the Company’s share capital is deemed to be a controlling shareholder. Also, you are deemed to have a personal interest if any member of your immediate family or their spouse has a personal interest in the adoption of the proposal. In addition, you are deemed to have a personal interest if a company, other than Bioblast Pharma Ltd. that is affiliated with you has a personal interest in the adoption of the proposal. Such company is a company in which you or a member of your immediate family serves as a director or chief executive officer, has the right to appoint a director or the chief executive officer, or owns 5% or more of the outstanding shares. However, you are not deemed to have a personal interest in the adoption of the proposal if your interest in such proposal arises solely from your ownership of the Company’s shares, or to a matter that is not related to a relationship with a controlling shareholder.
