  ITEM 5. - OTHER EVENTS
  
  On March 27, 2003, Sonex Research,  Inc. (the "Company")  posted the following
  announcement on its website (www.sonexresearch.com):
  
  
                          SONEX CHAIRMAN RESIGNS
  
  ANNAPOLIS,  MARYLAND,  March 27,  2003 - SONEX  RESEARCH,  INC.  (OTC BB:  SONX)
  announced today that Mr. John H. Drewanz resigned this week as a director of the
  Company.  He  submitted  his  resignation  on  March  24,  2003 to be  effective
  immediately.  Mr.  Drewanz,  a director  since October  2001,  had served as the
  Chairman  of the Board since  October 9, 2002.  The  Company  indicated  that no
  replacement for Mr. Drewanz has been named.
  
  According to Sonex CEO and founder Dr. Andrew A. Pouring, Mr. Drewanz told other
  directors  following  Monday's  quarterly Board meeting that he had made all the
  contributions he could as a director and believes Sonex is in capable hands with
  its current  management and other members of the Board. Mr. Drewanz,  a resident
  of the Annapolis,  Maryland,  area, is a private investor who spent thirty years
  as a college  professor at the University of Maryland,  University of Baltimore,
  American University and Anne Arundel (Maryland)  Community College.  Mr. Drewanz
  also owned his own real estate firm and has  developed  many  properties  in the
  Baltimore and Annapolis vicinity.

  ABOUT SONEX
  
  Sonex  Research,  Inc.,  a leader  in the  field of  combustion  technology,  is
  developing its patented Sonex Combustion  System (SCS)  piston-based  technology
  for in-cylinder  control of ignition and  combustion,  designed to increase fuel
  mileage and reduce  emissions  of internal  combustion  engines.  Sonex plans to
  complete development, commercialize and market its SCS Stratified Charge Radical
  Ignition  (SCRI)  combustion  process to the automotive  industry in response to
  forthcoming  increases in national  vehicle fuel mileage  standards.  Presently,
  high mileage, roomy and safe five-passenger  automobiles using gasoline,  direct
  injected (GDI) engines are sold only in Japan and Europe due to high  emissions.
  Sonex intends to conclusively  demonstrate that SCS-SCRI will enable GDI engined
  vehicles to achieve 50 mpg (highway) while meeting emissions standards to permit
  sale in the U.S. as a viable,  near-term  alternative to  longer-term  solutions
  such as  improvements  in hybrid  propulsion  systems  or years of  further  R&D
  required for fuel cell technology to become practical.
  
  Additionally, independent third-party testing has confirmed the potential of the
  SCS application for DI diesel engines to reduce harmful soot in-cylinder without
  increasing   fuel   consumption.   Sonex  is  pursuing   joint   marketing   and
  commercialization  programs  for the  SCS low  soot  technology  with  committed
  industrial partners.
  
  Other SCS designs are being used to convert gasoline engines of various sizes to
  operate on safer,  diesel-type  "heavy fuels" for use in military and commercial
  applications  requiring  light  weight and safe  handling  and  storage of fuel.
  Examples include UAVs (unmanned aerial vehicles) and ATVs (all-terrain vehicles)
  such as those used by U.S.  defense forces in  Afghanistan,  as well as outboard
  engines, small watercraft used as targets, and generator sets.
  
  
  CAUTION REGARDING FORWARD-LOOKING STATEMENTS
  
  "Forward-looking"  statements  contained  in this  announcement,  as well as all
  publicly disseminated material about the Company, are made pursuant to the "safe
  harbor" provisions of the Private Securities Litigation Act. Such statements are
  based  on  current  expectations,  estimates,  projections  and  assumptions  by
  management  with respect to matters  such as  commercial  acceptance  of the SCS
  technology, the impact of competition,  and the Company's financial condition or
  results of  operations.  Readers  are  cautioned  that such  statements  are not
  guarantees of future  performance and involve risks and uncertainties that could
  cause  actual  results to differ  materially  from those  expressed  in any such
  forward-looking statements.  Additional information regarding the risks faced by
  Sonex is provided in the  Company's  periodic  filings with the  Securities  and
  Exchange Commission under the heading "Risk Factors". Such filings are available
  upon request from the Company or online in the EDGAR database at www.sec.gov.
