hCDR 1 for the treatment of Lupus 

Systemic “Lupus” Erythematosus (SLE)  Lupus is a chronic, debilitating inflammatory autoimmune disease, resulting in r heumatologic, dermatological and end - organ manifestations

Lupus: Market Overview ▪ Prevalence 1 ▪ 1.5 million patients in the U.S. ( 5 million patients worldwide) v a r ying across ethnicities and geographies ▪ 90 % are women / majority between ages of 15 and 45 ▪ Prognosis ▪ Dermatologic & musculoskeletal manifestation most common early on ▪ End organs become involved as disease progresses ▪ Most common causes of death ▪ Renal failure ▪ Cardiovascular disease ▪ CNS disorders ▪ Intercurrent infections ▪ 10 - year survival rate for ~ 90 % of patients 1 Lupus Foundation of America 

Lupus: Competitive Landscape ▪ NO completely effective treatments for lupus in the market: ▪ Current treatments: corticosteroids, cytotoxic immune - suppressants (palliative care) ▪ Problems with current treatments: non specific, severe side effects (hypertension, osteoporosis, bone marrow suppression, increased cancer risk, etc.) ▪ Benlysta (HGS/GSK): approved by FDA 3 / 2011 ▪ Only approved drug against Lupus in the last 50 + years ▪ Unclear correlation between autoantibodies and disease severity ▪ Launch is slower than expected ( 2013 sales of 146 M £ vs. expected blockbuster) ▪ Weak pipeline: primarily B - cell inhibitors – like Benlysta 

hCDR 1 : General & Mechanism of Action (MOA) hCDR 1 is a peptide that down - regulates the SLE - related autoimmune process; potential to be “first in class” and “best in class” drug ▪ Specific upstream immunomodulation through the generation of regulatory T cells ▪ Developed by Prof. Edna Mozes of the The Weizmann Institute of Science (Israel) ▪ > 40 peer reviewed journal articles; > 200 animal experiments ▪ IP: Minimum of data exclusivity (~ 7 years US/ 10 years EU) with plans to extend ▪ XTL obtained exclusive license from Yeda Research and Development Co. ( 1 / 2014 )  MOA of hCDR 1 : Different than existing late stage pipeline

Clinical Trial History of hCDR 1 ▪ Three clinical trials completed (by Teva): Phase Ia, Ib trials and a Phase II (PRELUDE) trial ▪ Studies included over 400 patients ▪ Demonstrated to be well tolerated by patients and to have a favorable safety profile ▪ Phase II trial ▪ Did not meet primary endpoint (SLEDAI) ▪ Encouraging results in secondary clinical endpoint, the BILAG index (see below) ▪ 0.5 mg weekly dose showed a substantial effect ▪ Opportunity for hCDR 1 ▪ Teva returned hCDR 1 to Yeda in 2009 ▪ Thereafter, in 2010 , FDA published guidelines: secondary endpoint, BILAG (or SRI), should be the correct primary endpoint  hCDR 1 has been tested in over 400 patients, is safe and has shown encouraging results on BILAG – one of the FDA’s recommended primary endpoints for lupus trials

PRELUDE (Phase II) Trial Design  ▪ Primary endpoint (SLEDAI ) was not met ▪ Secondary and Exploratory Endpoints (BILAG, Flares) showed effect/trends ▪ Edratide seems to have a favorable safety profile and is well tolerated Non - compliance with Steroid Withdrawal Phase not a protocol violation

BILAG Responder Analysis at LOV Compared to Baseline (Placebo vs. Edratide 0.5 mg) PRELUDE - Secondary Endpoint (Pre - defined/ITT Cohort)  n= 83 n= 76 Substantial effect (p= 0.03 ) even though steroid withdrawal not enforced (see below)

BILAG Complete Responder Analysis (Placebo vs. Edratide 0.5 mg) Subjects with BL Steroids < 20 mg daily dosage (n= 137 ; p= 0.007 ) Subjects with no Steroids at Baseline (n= 29 ; p= 0.05 ) PRELUDE - Secondary Endpoint (Post Hoc) n= 69 n= 68 n= 16 n= 13 Clear trend toward even more substantial effect with reduced steroid use 

PRELUDE – Trends in other Secondary Endpoints  * Predefined: an increase of ≥ 5 mg daily steroids compared to baseline ** Post Hoc: increase of ≥ 5 mg daily steroids vs. lowest previous dose SLE Responder Index* (Post Hoc/ITT Cohort) p= 0.058 Medicinal Flare Analysis (Post Hoc/ITT Cohort) p= 0.04 SRI in PRELUDE trial was composite measure of disease activity based on two validated indices: SELENA - SLEDAI and BILAG *

Clinically Advisory Board ▪ Dr. Daniel Wallace, Cedars - Sinai Medical Center ▪ Largest lupus practice of its kind in the US; currently running > 30 clinical trials ▪ Served as Chairman of the Lupus Foundation of America, receiving the Lupus Foundation of America Award, Achievement Award of the Lupus Research Institute and others " I am privileged to join the team at XTL to help advance what I believe to be one of the most promising Lupus drug candidates in recent history . The data shown in earlier trials is encouraging and could potentially be a disruptive solution to a largely unmet medical need .” ▪ Professor David Isenberg, University College London Hospitals ▪ Chair of the British Isles Assessment Group (BILAG ). ▪ President of the British Society for Rheumatology from 2004 – 2006 ▪ Chaired the Society’s Biologics Register Committee from 2006 – 2011 ▪ Received the 2010 Evelyn Hess Prize from the Lupus Foundation of America and the Rodger Demers Prize (Canada), in 2012 . “I am happy to serve as a consultant for XTL’s Phase II trial testing for hcDR 1 using the BILAG index because it has shown encouraging results when used during the previously conducted PRELUDE trial .” ▪ Dr . Murray Urowitz, University of Toronto; Lupus Clinic at Toronto Western Hospital ▪ Established the University of Toronto Lupus Clinic and Lupus Databank Research Program . ▪ Founding member/president of numerous lupus - related associations and the recipient of numerous awards for his contributions to lupus research. "The continued development of XTL’s hCDR 1 has the medical community eagerly waiting to learn the efficacy of the drug in its planned Phase II trial.” 

New Phase 2 b Trial: Improve Probability of Success Proposed trial design is based on: ( 1 ) new FDA guidelines; ( 2 ) Benlysta trials; and ( 3 ) clinical data from PRELUDE - especially the 0.5 mg results in the secondary endpoints PRELUDE Trial Proposed Phase 2b Primary endpoint SLEDAI only BILAG Substantial Responders Dose 0.5, 1, 2.5 mg 0.5, 0.25 mg Steroid Use Corticosteroids masking Steroid sparing not enforced Defined regimen of steroids Mandatory and enforced Trial duration 26 week study Extend to 52 weeks Execution Site discrepancies in disease matrices Suboptimal sample & data handling Training and monitoring Specialized CRO

▪ Clinical observation on advanced MM patients treated with rHuEPO for anemia ( 1990 s; Prof. Mittelman) : ▪ Corrected the anemia ( Hb rise) – known effect ▪ A novel biological effect: Patients lived ~ 36 - 90 months longer than expected! ▪ Extensive clinical/basic research with human patients and mice models: ▪ rHuEPO has an anti - myeloma effect ▪ rHuEPO induces myeloma regression ▪ rHuEPO prolongs survival of advanced - stage MM patients ▪ MOA: stimulation of the immune system ▪ Published in medical literature Clinical Trial History of rHuEPO for Use with MM Patients 

rHuEPO for MM: Phase 2 Study ▪ Study Design : Study to assess the safety and effect on survival of rHuEpo in patients with advanced multiple myeloma ▪ ~ 30 patient, open label study to be conducted primarily in Israel ▪ Company already started the regulatory work with the FDA ▪ Regulatory approvals for start of trial expected 1 H 2015

XTLbio – Summary ▪ XTL has three Phase II assets; current focus on two of the assets (hCDR 1 / rHuEPO ) ▪ Both address a significant unmet medical need ▪ Both have compelling clinical data ▪ hCDR 1 has robust data on > 400 patients on the FDA recommended endpoint ▪ rHuEPO for MM has shown significant survival benefit ▪ XTL plans should result in clinical data in a reasonable amount of time ▪ If either trial is successful, should result in significant value appreciation ▪ XTL believes game plan is achievable ▪ Finance requirements believed to be reasonable/manageable ▪ XTL believes it can manage the two proposed clinical trials simultaneously
