Summary                   Company Overview

Partnering Interests:     Green Cross Corporation (GCC) is one of the leading research based biomedical and pharmaceutical
                          companies in Korea. The corporate headquarter and R&D facilities are located Yongin. GCC has 4
Co-development and
                          production plants including newly built vaccine production plant in Hwasun and biologics production
                          plant in Ochang. Since its establishment in 1967, GCC has pioneered in the field of
                          biopharmaceuticals, such as vaccines, plasma-derivatives, diagnostics, recombinant proteins and
                          therapeutic antibodies.

                          Historically, GCC has been well known for the R&D and commercialization of ‘Hepavax B’, a
                          world's biggest selling hepatitis B vaccine, ‘Hantavax’, a world’s first epidemic hemorrhagic fever
                          vaccine, and ‘Suduvax’, a world’s second chicken pox vaccine. Starting from the nation’s first
                          Albumin production in 1971, it currently manufactures more than 12 plasma fractions including
                          immunoglobulins, antihemophilic factors, and antithrombin factor. Manufacturing over 250
                          diagnostic reagents in 41 items, GCC is the leader in the nation’s diagnostic reagent sector. Recent
                          innovations include ‘BDD rhFVIII (Greengene)’, a recombinant human coagulant factor VIII.

                          With continuous investment in R&D, its portfolio now includes gene/cell therapeutics and small
                          molecule drugs. In 2008, GCC earned $516.1 million in revenue recording it as Korea’s fifth
                          pharmaceutical company and invested $41.5 million in R&D which is one of the biggest in Korea.

                          Opportunity Highlights

                          GCC focuses its research effort on basic and applied science in oncology, infectious diseases
                          (vaccines and therapeutics), genetic blood disorder, inflammatory diseases, and CNS diseases.
                          Of those therapeutic areas, most of the GCC’s current portfolio can be grouped into development of
                          vaccines, therapeutic proteins (recombinant proteins and antibodies), and small molecules.
                          GCC aim to expand its presence in the global market through collaborations and out-licensing while
                          seeking to collaborate or acquire products and technologies to strengthen our pipeline and the R&D

 Albumin-      B-
 Albumin-free, B-domain deleted recombinant human coagulation factor VIII

Summary                  Introduction
                         Hemophilia A is a X- linked genetic disorder that affects 1-2 individuals per 10,000 males. It is
Indication:              caused by deficiency for or structural abnormality of blood coagulation factor VIII (FVIII). The
                         human plasma-derived coagulation FVIII, which has been used as a conventional therapeutic agent, is
Hemophilia A
                         effective but considered to carry a risk of contaminations with blood-borne pathogens such as HIV
                         and hepatitis viruses.
Development Stage:       To overcome the safety concern, we have produced BDD rhFVIII (Greengene, B-domain deleted
NDA filing scheduled     recombinant human coagulation FVIII) using a mammalian cell culture system (approved by Korea-
for 2010                 FDA in 2008). We are currently developing BDD rhFVIII A/F (GC1101, albumin-free BDD rhFVIII)
                         with advanced virus clearance and inactivation processes to improve safety even further.

  Recombinant Human Parathyroid Hormone(1-84)

Summary                   Introduction
                          PTH (parathyroid hormone) is a peptide of 84 amino acid residues that is synthesized in and secreted
Indication:               from the parathyroid gland. It is a major regulator of calcium and skeletal homeostasis, acting
Osteoporosis              primarily through its receptor on target cells in bone and kidney. Unlike its physiological role as a
                          catabolic molecule, the intermittent administration of PTH mediates anabolic increase of bone mass
Development Stage:        as has been demonstrated in clinical studies. This unusual property of PTH is being exploited and
                          several drugs have been launched.
Phase I and II clinical
studies were completed    PTH, as a therapy for osteoporosis, is unique in that it is anabolic in bone, as compared to currently
in US, UK and             available therapies such as estrogen, calcitonin and bisphosphonates which are all anti-resorptives.

  Recombinant human kringle domain V of apolipoprotein(a)

Summary                  Introduction
                         Lipoprotein(a) (Lp(a)) consists of an LDL-like particle and the specific apolipoprotein(a) (apo(a)),
Indication:              which is covalently bound to the apoB of the LDL-like particle. Apo(a) is mainly synthesized in the
Hormone refractory       liver and is characterized by its repetitive kringle domains. Kringle domain is a 106~114 amino acid
prostate cancer, anti-   long protein motif arranged in a triple loop structure. Of the kringle domains in apo(a), the kringle
metastasis               domain V shows a significant sequence homology with the kringle domain V of plasminogen, which
                         is reported to have a strong angiogenetic effect.
Development Stage:       MG1102 is a 86 amino-acid long recombinant human kringle domain V of apolipoprotein(a) (rhLK8)
Non-clinical / phase I   and it is produced in yeast Saccharomyces cerevisiae. Anti-angiogenetic effect of MG1102 has been
IND                      shown previously using in vitro and in vivo assays such as CAM assay (a neovascularization assay in
                         chicken embryo) and the Matrigel plug assay and anti-cancer effect has been proven using in vivo
                         cancer models.

Development Stage:
                         Treatment of Hunter syndrome has mostly been involved in management of the symptoms and
                         complications. Bone marrow graft, while it improves most symptoms associated with Hunter
