The goal of this campaign is to familiarize the investment community with the progress Entropin is achieving in the development of Esterom(R). Esterom(R) is a revolutionary new topical drug which has the potential to replace other current therapeutics for treating impaired physical function resulting from painful soft tissue injuries and diseases - such as tendonitis, bursitis and lower back sprain. Entropin has begun a series of presentations that will include more than twenty U.S. cities. Members of Entropin's executive management team will meet with fund managers, brokers and analysts. The Company is also conducting an extensive direct mail program to inform the financial community of the Company's progress. The Company's presentation is based on publicly available information and focuses on the unique characteristics of Esterom(R), the protocol design for the current clinical trial, the Company's scientific, development and research partners, as well as, Entropin's business strategy and its development timeline for Esterom(R).

We are enthusiastic about the anticipated outcome of our current clinical trial and want to share our story with investors." Dr. Tachovsky went on to add, "Our goal is to reach a broad audience within the investment community." On September 25, 2001, the Company announced that it had begun its current clinical trial. This Phase II/III Study is a double blind, placebo- controlled study designed to treat 150 patients for shoulder pain and disability. Non-placebo patients will receive treatments of 10% Esterom(R) solution on three consecutive days with a seven-day follow-up period. The study has clearly defined endpoints and will employ validated measurement tools to determine the effect of Esterom(R) treatments. The Company expects enrollment of the 150 patients to take approximately six months. Entropin has contracted with Medidata Solutions for state-of- the-art on-line centralized data capture to provide real-time monitoring and to shorten the time required to analyze the data when the study is complete. Based on the time required to recruit patients that meet the study's diagnostic entry criteria, the Company anticipates releasing the results of this study in the first half of 2002. 2 Entropin, Inc. is a specialty pharmaceutical research and development company focused on the development of Esterom(R), a revolutionary new topical product with the potential to replace other current therapeutics for treating impaired physical function resulting from painful soft tissue injuries and diseases -- such as tendonitis, bursitis and lower back sprain.
