This excerpt taken from the BNVI DEF 14A filed Apr 22, 2008.
Why am I receiving these materials?
We have sent you this proxy statement and the enclosed proxy card because the Board of Directors of Bionovo is soliciting your proxy to vote at the 2008 Annual Meeting of Stockholders. You are invited to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card.
We intend to mail this proxy statement and accompanying proxy card on or about April 24, 2008 to all stockholders of record entitled to vote at the annual meeting.
