MEDIA RELEASE PR41472 
 
NeoStem Presented at NASDAQ MarketSite in New York to Discuss Entry Into Merger Agreement With 
Progenitor Cell Therapy 
 
NEW YORK, Sept. 27 /PRNewswire-AsiaNet/ -- 
 
    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 (TM) 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.
