Highlights

During the second quarter of 2013:

• Announced positive phase I clinical results for its H5N1 vaccine in a
  trial run by IDRI. The vaccine was found to be safe and well-tolerated
  and induced a solid immune response exceeding the three CHMP (Committee
  for Medicinal Products for Human Use) immunogenicity criteria for
  licensure of influenza vaccines. The vaccine was tested in three
  different configurations: using IDRI’s Glucopyranosyl Lipid A (“GLA”)
  formulated adjuvant, given both intramuscularly and intradermally, and
  using alum intramuscularly. All three configurations exceeded the CHMP
  criteria.
• Raised $3.5 million through a private placement of 6.25 million common
  shares.
• Successfully produced a VLP vaccine candidate for the H7N9 virus
  responsible for recent influenza outbreak in China and first in the
  world to report positive interim preclinical results
• Produced a plant-based Rotavirus VLP vaccine candidate comprising all
  four structural antigens of rotavirus (VP2, VP4, VP6 and VP7) using
  Medicago’s plant-based manufacturing platform.
• Was granted a patent for Influenza Virus-Like Particles in Plants
• Received authorization from Health Canada and commenced Phase II
  clinical trial for an H5N1 vaccine

Outlook for the remainder of 2013

• Closing of the transaction with MTPC, following the approval by the
  shareholders and receipt of all regulatory approvals, is expected to
  occur by mid-September 2013
• Interim data from a Phase II H5N1 clinical trial expected in the second
  half of this year
• Initiation of a US Phase II clinical trial for a quadrivalent seasonal
  influenza vaccine with interim data expected in the second half of this
  year.

About Medicago

Medicago is a clinical-stage biopharmaceutical company developing novel
vaccines and therapeutic proteins to address a broad range of
infectious diseases worldwide. The Company is committed to providing
highly effective and competitive vaccines and therapeutic proteins
based on its proprietary VLP and manufacturing technologies. Medicago
is a worldwide leader in the development of VLP vaccines using a
transient expression system which produces recombinant vaccine antigens
in plants. This technology has potential to offer more potent vaccines
with speed and cost advantages over competitive technologies, enabling
the development of a vaccine for testing in approximately one month
after the identification and reception of genetic sequences from a
pandemic strain. This production time frame has the potential to allow
vaccination of the population before the first wave of a pandemic, and
supply large volumes of vaccine antigens to the world market. Medicago
also intends to expand development into other areas such as biosimilars
and biodefense products where the benefits of our technologies can make
a significant difference. Additional information about Medicago is
