Forward Looking Statement This presentation contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. These statements are based on management’s current expectations and beliefs and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. The forward-looking statements contained in this presentation include statements about future financial and operating results, and risks and uncertainties that could affect CTI’s product and products under development. These statements are not guarantees of future performance, involve certain risks, uncertainties and assumptions that are difficult to predict, and are based upon assumptions as to future events that may not prove accurate. Therefore, actual outcomes and results may differ materially from what is expressed herein. In any forward-looking statement in which CTI expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the statement or expectation or belief will result or be achieved or accomplished. The following factors, among others, could cause actual results to differ materially from those described in the forward-looking statements: risks associated with the closing of the acquisition and with the synergies expected from the acquisition, as well as risks associated with preclinical, clinical and sales and marketing developments in the biopharmaceutical industry in general and in particular including, without limitation, the potential failure of XYOTAX™, pixantrone, and Brostallicin to prove safe and effective for treatment of non-small cell lung and ovarian cancers, non-Hodgkin’s lymphoma, and sarcoma, respectively, potential determinations by regulatory, patent and administrative governmental authorities, competitive factors, technological developments, costs of developing, producing and selling CTI’s products under development; and other economic, business, competitive, and/or regulatory factors affecting CTI’s business generally, including those set forth in CTI’s filings with the SEC, including its Annual Report on Form 10-K for its most recent fiscal year and its most recent Quarterly Report on Form 10-Q, especially in the “Factors Affecting Our Operating Results” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections, and its Current Reports on Form 8-K. Except as may be required by Italian law, CTI is under no obligation to (and expressly disclaims any such obligation to) update or alter its forward-looking statements whether as a result of new information, future events, or otherwise. 2 Why Acquire SMI CTI gets WW rights to Brostallicin, a phase II/III “first in class” drug candidate which could reach market by 2010 Fills pipeline gap with late stage drug candidate with low risk development program Leverages CTI’s solid tumor sales force under NVS agreement following potential Xyotax launch in NSCLC in 2009 Synergistic partnership with prestigious Nerviano Medical Sciences (NMS), Milan NMS/Farmitalia discovered Anthracyclines first class of DNA MAJOR groove binding agents NMS scientists discovered Brostallicin first synthetic class of DNA MINOR groove binding agents 3 Why Acquire SMI Establishes partnership with unprecedented team of genomic scientists and translational clinical trial experts coupled with pharmaceutical drug development expertise (Dan Von Hoff) Ideal complement to our Bresso development capabilities Guide current and future drug development direction Multiple partnership opportunities with big pharma Cost effective to SMI’s business plan with ~$10M cost savings/year over stand alone model Purchase price attractive; similar to Series A venture investors Superior terms than potential co-development relationship Adds biotech expertise to CTI Board Richard Love ex CEO Ilex Oncology 4 Deal terms summary $20,000,000 in unregistered CTIC stock $5,000,000 in cash or stock at CTI’s option upon 5 day average price prior to execution FDA special protocol agreement to a single pivotal trial for Brostallicin® $10,000,000 in cash or stock at CTI’s option upon regulatory approval of Brostallicin® 5 Deal terms summary SMI to become wholly owned subsidiary of CTI Unit to focus TGEN relationship on acquiring new drug candidates and targeting current drug candidates using COV approach to increase probability of success and shorten time to market Current management to continue to run operations Jeff Jacobs, CEO SMI Tim Williamson, CBO SMI Dick Love to join CTI’s Board of Directors Dan Von Hoff to lead CTI’s Strategic Portfolio Development Board Operations and Brostallicin® development will add <10% increase in operating expenses to combined company P&L over next 2 years 6 Overview SMi’s Competitive Edge Using their expertise in clinical trials and functional genomics to: Define clinical and/or genomic abnormalities that makes a patient’s tumor susceptible to a specific therapeutic agent Implement unique clinical trial designs to obtain rapid approval of new anticancer agents (“context of vulnerability”) 8 The Context of Vulnerability Reducing the risk of drug development… …by picking the right patients for a given drug -Increased efficacy -Faster, less expensive development. -High value targeted markets Informing clinical studies with genomic and mechanistic information 9 Brostallicin® a new class of anti-cancer agents: minor groove binder H N Br NH2 NH O NH NH O H N N NH H N O N O N O N 10 DNA STRUCTURE MAJOR GROOVE Proteins that interact with DNA often make contact with the edges of the base pairs that protrude into the major groove.
