SANTA ANA, Calif., June 18, 2002 (PRIMEZONE) -- National Capital Securities, Inc. (formerly known as Donner Corp. International), a subsidiary of National Capital Companies, Inc. (Pink Sheets:NATC), announced today that it released its Speculative Buy Recommendation on HyperBaric Systems, Inc. (OTCBB:HYRB).

The report, which can be found at www.donnercorp.com, highlighted the Company's potential to dominate an enormous global market that is demanding advancements in technology that allow for the extended storage and preservation of biomaterials.

National stated in the report that HyperBaric's technology represents a long-awaited solution to blood platelet spoilage, which results in millions in lost revenue to hospitals and blood centers. HyperBaric has made a breakthrough in research and development in the field of living biological material storage and preservation. By enabling organs and blood platelets to be preserved for a longer time and higher quality level than ever before, HyperBaric's technology represents an important complement to other emerging life-saving technologies.

HyperBaric's technology consists of a set of liquid solutions, a lightweight, portable device for cooling and processing, and the protocols for using the solutions and device. The Company is currently preparing to conduct human infusion tests, a major step in the regulatory path to FDA approval, and is also commencing a comprehensive study to test its technology on extending the preservation periods for donor organs. Preservation technology has the potential to prolong the shelf life of blood platelets and other collected biological materials. This medical breakthrough could greatly increase the global availability of precious living biological materials needed to save human lives and hundreds of millions of dollars each year in medical costs.

HyperBaric believes there are a number of benchmarks that investors should watch for during 2002-2003:


 -- Announcement of pre-clinical trials for human infusion testing to
    begin at one of America's leading blood laboratories during the
    summer of 2002.  
 -- Initiation of FDA testing.  The Company believes this could happen
    as early as the end of 2002, or by early 2003.  
 -- FDA approval for beginning and successfully completing
    pre-clinical trials.  
 -- One or more licensing agreements by 2003.  HyperBaric intends to
    enter into several licensing agreements with one or more major
    companies that sell products to blood centers and hospitals.
