While the Company anticipates being able to update stockholders on these matters prior to 16 June 2020 at 6:00 pm (EDT), which is 17 June 2020 at 8:00 am (AEST), the Board is concerned that stockholders will not have sufficient time in which to absorb the information provided in the update and to then determine how to vote on the delisting resolution or whether to change an existing vote. By further postponing the Special Meeting the Board believes that stockholders will be provided with a reasonable period in which to consider the information and to then make an informed vote with respect to delisting proposal The further postponement of the Special Meeting is not, however, a guarantee that a significant financing will become available prior to such m Meeting, or ever, on terms acceptable to the Company. Voting Details The Special Meeting will be held as a webcast via the online platform at https://agmlive.link/GID20 and details on how to access the meeting can be found on the Company’s website or within the definitive proxy statement (the “Proxy Statement”) that was attached to the Company’s announcement on 27 May 2020 AEST. If you have already voted your shares of common stock or directed CHESS Depositary Nominees Pty Ltd (“CDN”) to vote your CHESS Depositary Interests (“CDIs”) by completing the CDI Voting Instruction Form and you do not desire to change your vote, your prior vote will remain voted without the need for you to take any additional action. If you held shares of common stock on the Record Date and have not yet voted, you may do so now using the directions provided in the Proxy Statement. If you held shares of common stock on the Record Date and have already voted, you may change your vote or revoke your proxy at any time before the Special Meeting in any one of the following ways: • if you received a proxy card, by signing a new proxy card with a date later than your previously delivered proxy and submitting it as instructed in the Proxy Statement; • by re-voting by Internet as instructed in the Proxy Statement; • by notifying the Company’s corporate secretary in writing at GI Dynamics, Inc., 320 Congress Street, Boston, MA 02210, U.S.A., Attention: Corporate Secretary, before the Special Meeting that you have revoked your proxy; or • by virtually attending the Special Meeting, revoking your proxy and voting via the online platform at https://agmlive.link/GID20. Virtual attendance at the Special Meeting will not in and of itself revoke a previously submitted proxy. You must specifically request during the Special Meeting that it be revoked. Your most current vote, whether by Internet or proxy card, is the one that will be counted. If you are a beneficial owner and hold shares of common stock through a broker, bank or other nominee, you may submit new voting instructions by contacting your broker, bank or other nominee. If you held CDIs on the Record Date and you have not yet directed CDN to vote by completing the CDI Voting Instruction Form, you may do so prior to 8:00 a.m. AEST on 18 June 2020 (which is 6:00 p.m. EDT on 17 June 2020). If you held CDIs on the Record Date and you have already directed CDN to vote by completing the CDI Voting Instruction Form, you may revoke those directions by delivering to Link Market Services Limited a written notice of revocation bearing a later date than the CDI Voting Instruction Form previously sent which notice must be received by Link Market Services Limited no later than 8:00 a.m. AEST on June 18, 2020 (which is 6:00 p.m. EDT on June 17, 2020).
