NeoStem, Inc. Presented at NASDAQ MarketSite in New York to Discuss Entry Into Merger Agreement With Progenitor Cell Therapy

NEW YORK, Sept. 27 /PRNewswire-FirstCall/ -- NeoStem, Inc. (NYSE Amex: NBS) ("NeoStem" or the "Company"), an international biopharmaceutical company with operations in the U.S. and China, appeared on Thursday at the NASDAQ MarketSite in Times Square in connection with its announcement of the signing of a definitive merger agreement whereby NeoStem will acquire Progenitor Cell Therapy.

The definitive merger agreement provides for the issuance of an aggregate of 11,200,000 shares of NeoStem common stock in exchange for all of Progenitor Cell Therapy membership interests. The bulk of these shares will be held in an escrow account for at least one year from closing and will not be available for sale. Additional consideration includes warrants to purchase an aggregate of no less than 1,000,000 and a maximum of 3,000,000 additional shares of NeoStem common stock at $3, $5 and $7 exercise prices. Holders of greater than 50% of NeoStem's common stock and greater than 50% of PCT's membership interests have agreed to vote in favor of the merger.

Dr. Smith discussed how this acquisition is a significant step in NeoStem's efforts to develop a "one-stop-shop" for global cell therapy and highlighted key considerations in the merging of the two companies, including:

• In 2009, PCT generated over $8,000,000 in revenue. Its business will be accretive to NeoStem's growing adult stem cell operations and PCT has demonstrated that cellular therapy can be a revenue generating business.
• PCT's management will remain in place. They bring over 100 years of collective experience in the business and science of cell therapy and its development.
• Since its inception in 1999, PCT has performed over 30,000 cell therapy procedures in its cell therapy manufacturing facilities and processed and stored over 18,000 cell therapy products (including umbilical cord blood units, blood and marrow derived stem cells and dendritic cells).
• PCT has served over 100 clients from around the world and is experienced with more than 20 different cell based therapeutics. Most exciting is the fact that over 5,000 patients have been treated with the cell therapy products that have been logistically arranged and transported by PCT
• PCT has played an instrumental role in the manufacturing of Provenge throughout the clinical trial process, that has led to Dendreon's successful FDA approval of the first major autologous cellular immunotherapy. We believe PCT's core competencies in cell therapy development will contribute to moving forward NeoStem's proprietary VSEL Technology.
• Additionally, between NeoStem's autologous adult stem cell collection capabilities and PCT's umbilical cord blood collection and long term storage services, the combined company will be the first of its kind to provide families autologous stem cell collection and storage with current Good Manufacturing Practices (cGMP)".

The closing of the merger is subject to various conditions, including the approval by NeoStem's stockholders of the issuance of NeoStem's securities in the merger.
