1 S.I.S Venoms For Humanity S.I.S Shulov Innovative Science Ltd. A biopharmaceutical company focused on the discovery and development of novel human therapeutics. April 2013

2 Background1 S.I.S Shulov Innovative Science Ltd. was founded by the late Prof. Aharon Shulov and Mr. Aviv Marx. Prof. Aharon Shulov (1907-1997) > Dept. of Zoology at the Hebrew University of Jerusalem, Founder and General Manager of The Jerusalem Biblical Zoo for over 40 years. > Proposed a research program to identify the analgesic components of snake venom Mr. Aviv Marx > Entrepreneur and family friend provides funding.

3 > Novel non-toxic short peptide has been isolated from snake venom based on its highly potent in-vivo analgesic activity upon topical application > Based on the above novel molecule a whole family of relatedcompounds has been identified in various snake venoms > One of the naturally occurring peptides (coded Zep-4) and its chemically modified version coded Zep-3, were chemically synthesized in gram quantities. > These peptides were formulated as a cream and assessed for their analgesic and anti-viral activities and for the treating of psoriasis symptoms upon topical application on the skin. Innovation2

4 Intelectual Property3 S.I.S has been granted a key patent in the US which is in various stages of approval worldwide > US Patent - 7220725 Composition comprising an analgesic peptide and therapeutic use thereof > As of March 2012, a new PTC patent (#PCT/IL2012/050105) was submitted (U.S. application - # 61/468,212) “Method for treating disorders of the skin” claiming the therapeutic use of the peptides as a treatment for viral induced clinical symptoms, such as HSV1 induced cold sores, HSV2 induced Genital Herpes and Psoriasis.

5 > Analytical and bio-analytical assays to trace the products in buffers and in body fluids have been developed. > The % of trans-dermal permeability has been determined in a Franz cell model (permeability via pig’s ear skin is less than 0.1%) > Local Irritation Study is being performed > Local Sensitization study is being performed > Gynotoxicity studies are being performed > A mice model that mimics the clinical symptoms upon infection with HSV1 is being established > Anti viral activity was established In- vitro and In- situ. > Determination of product stability Development Studies4

6 Current status of SIS's products5 > S.I.S has conducted a large variety of pre-clinical studies in accordance with the requirements of the health regulatory authorities and in order to support the development processes of Zep-3 and Zep-4 cream as a product and to establish its safety and efficacy. > S.I.S has completed all essential toxicology and safety studies required for the submission of a file for Phase I Clinical Study. > Zep-3:, Zep -3 is in Phase I clinical study (at the Dep. of Dermatology, Shiba Hospital, Israel). After concluding the study (Q2, 2013) we will initiate a Phase II study for HSV1 Cold Sores indication and a Phase II study for the Genital Herpes indication. > In relation to HSV1 infection, Zep -3 is a fast acting drug, which causes an immediate relief from pain and itching within less than 5 minutes and prevents lesion formation within 36 hours. Furthermore, it seems to have no adverse side-effects.

7 Inhibition of HSV1 replication and spreading in tissue culture 6 > The anti HSV1 activity of Zep-3 is determined by measuring plaque forming, using tissue culture vero cells in vitro. > The results depicted below are representative of one out of six repeated experiments using two different batches of Zep - 3 > Infected HSV1 treated with Zep-3 (4mg/ml or 8mg/ml) > Infected HSV1 treated with “Scrambled” peptide (4mg/ml or 8mg/ml). > “Scrambled” refers to the identical amino acids such as Zep-3 but in altered sequence > The anti-viral effect was produced without causing Cell Toxicity in the Control Vero Cells

8 Inhibition of HSV1 Replication by Zep-3 7 Zep – 3 (4mg/ml ) Zep – 3 (8mg/ml) Scramble (4mg/ml) Scramble (8mg/ml)

9 Zep-3 Inhibits Virus Replication in tissue culture 8 Control - No Peptide Zep-3 > Zep-3 inhibits in dose dependent manner the replication of HSV1 in Vero cells

10 Inhibition of HSV1 Replication by Zep-3 in Organ Skin Culture 9 Control - None Infected HSV1 - Infected HSV1 – Infected + Scramble (8mg/ml) HSV1 – Infected + ZEP-3 (8mg/ml)

11 Zep-4 for Treating Psoriasis10 >Anecdotal data indicates that Zep-4 upon topical application is efficient for treating psoriasis in patients. > Zep-4 relieves itching and redness.

12 Safety and Toxicology of Zep-3 and Zep-4 11 > Safety studies were carried out in rats in which the following end points were recorded: body weight Vitality blood picture Internal organs histopathology > No adverse side effects were observed at twice a week administration (topical or I.V.) of high dosages for 200 days

13 Trans Dermal Permeability of Zep-3 and Zep-4 12 > Dermal Permeability was tested using the ear-skin pig model. > Zep-3 and Zep-4 show permeability profile below 1% after 24 hrs. > Significant amount of drug accumulated in the skin.

14 > The total skin disorders market is estimated to be $28 Billion annually (for 2011), about 1 / 3 of which is due to viral infections, most of these being the Herpes virus (HSV1, HSV2 and Herpes Zoster ) > By the age of 40, nearly 90% of adults, have been exposed to HSV1, 15% of those exposed to HSV1 may develop symptoms (blisters, cold sores) every year. >In the Western World (U.S., Europe and Japan) the potential market is over 100 Million patients, these patients develop clinical symptoms every year. HSV1 - The Market 13

15 > Globally, about 4.0 billion people are estimated to be infected with Herpes Virus > The incidence rate of cold sores, caused by the HSV1 virus, is the second largest worldwide, trailing only behind common cold > About 79% of the U.S. population is infected with HSV1, with about 25-35% of the adults enduring recurrent spate of cold Sores > in recent years HSV1 has become the most common cause of newly diagnosed genital herpes infections ”The need for innovative therapies for the treatment of herpes simplex infection, and the search for novel antiviral drugs continues. This presents a huge potential for the growth of herpes simplex therapeutics market in future”. (Global Industry Analysts, Inc.) HSV1 – The Market (continue) 14

16 >Above 40% of genital Herpes is caused by HSV1 and Zep-3 presents a possible prevention as well as cure. HSV1 - The Market (Contd.) 15

17 Psoriasis - Market16 Psoriasis is a chronic skin disease that is the most prevalent autoimmune disease in the U.S., with as many as 7.5 million Americans affected (2.45% of the population). Psoriasis Market Info™ captures all the relevant data on this disease. The overall market value is $1.8+ billion in 2010 in the U.S alone and $3.4 billion world-wide. This market is expected to grow significantly in the future, largely due to the chronic nature of the disease, the high unmet and continued need for topical therapies which will make this market approachable for any new therapy that is both effective and safe.

18 Summary of Zep-317 > Zep -3 upon topical application inhibits/prevents within less than 5 minutes the itching and pain induced by Herpes Simplex Virus Type I (HSV1) and eliminates swelling and blister formation in less than 36 hours > Zep – 3 inhibits in a dose dependent manner the replication of HSV1 in Vero cell line infected by the virus > Zep-3, demonstrates analgesic properties in acute and chronic pain animal models

19 Summary of Zep-418 > Zep-4 upon topical application is efficient for treating psoriasis in patients. > Zep-4 relieves itching and redness associate with Psoriasis.
