ITEM 5. - OTHER EVENTS

     On September 3, 2002, Sonex  Research, Inc. (the  "Company") posted the
following notice to shareholders on its website (www.sonexresearch.com):



                     SONEX SCHEDULES 2002 ANNUAL MEETING;
                  LETTER TO SHAREHOLDERS POSTED TO WEBSITE


ANNAPOLIS,  MARYLAND,  September 3, 2002 - SONEX  RESEARCH,  INC. (OTC BB: SONX)
announced  that the 2002  Annual  Meeting  of its  shareholders  will be held on
Wednesday,  October 9, 2002, at 10:00 a.m.  local time in the Dorsey Room in the
Hampton Inn & Suites,  located in the ARINC  Corporate  Park,  124 Womack Drive,
Annapolis, Maryland. (Tel: 410-571-0200).

The Company  indicated that  shareholders  could expect to receive related proxy
materials  in  mid-September.  Following  is the  full  text  of the  Letter  to
Shareholders  that will appear in the Sonex 2001 Annual  Report  included in the
proxy materials.


                                                                 August 2002

Dear Fellow Shareholders:

Sonex will hold its Annual  Meeting here in Annapolis on October 9, 2002,  and I
look forward to seeing many of you at that time. In preparation for the meeting,
I offer this brief  overview of the  Company's  recent  activities  and progress
toward the refinement and commercialization of the Sonex Combustion System (SCS)
for in-cylinder control of ignition and combustion in engines.

At the end of 2001,  financial  constraints  resulted in a reduction in staffing
and Sonex officers  voluntarily deferred receipt of all salaries for an extended
period.  The Company also received  substantial  cooperation  from its part-time
consultants and legal and auditing  professionals  in terms of flexible  payment
arrangements.  These  reductions  in  cash  outflows  combined  with  additional
financial  support from investors and modest contract revenue helped the Company
persevere. Today, Sonex finds itself with numerous business opportunities and is
increasing staffing to support new projects.

**   In early August 2002 we  announced  the award of a $200,000  Department  of
     Defense (DoD)  subcontract to begin the conversion of a gasoline  engine to
     start and  operate on  diesel-type,  kerosene-based  military  fuels  (also
     referred to as "heavy  fuels") for use in an unmanned  aerial vehicle (UAV)
     weapon system. The DoD prime contractor, Science Applications International
     Corporation  (SAIC),  is a leader in the development of advanced gun weapon
     systems including launchers and smart projectiles.  Following the selection
     of a  commercially  available  70hp  to  80hp  lightweight,  spark-ignited,
     two-stroke,  gasoline  engine,  Sonex  will  begin  development  of an  SCS
     modified  combustion  chamber  design and  proprietary  starting  system to
     permit  the  converted  engine to start and  operate on heavy  fuels.  This
     initial  funding  permits a multi-phase  heavy fuel engine (HFE) program to
     begin  immediately,  while follow-on  funding needed to complete the design
     and testing  process to achieve a prototype  HFE is expected to be approved
     by  the  DoD  sponsor  later  this  year.  Sonex  is  pursuing   additional
     commercialization  opportunities  for  HFEs as a  result  of U.S.  and NATO
     military  directives  for a single  battlefield  fuel that  will  eliminate
     gasoline in favor of less volatile heavy fuels.

**   Late in 2001 one the world's  leading  engine  engineering  and  powertrain
     consulting  firms,  Ricardo  Consulting  Engineers Ltd,  confirmed the soot
     reduction  capability of the SCS "Low Soot" design.  Ricardo  published the
     findings, plus additional results from a later Computational Fluid Dynamics
     study of the  combustion  process,  in a paper  presented at the Society of
     Automotive Engineers' May 2002 Fuels and Lubricants Conference.  Ricardo is
     introducing the SCS "Low Soot" design results to potential  customers,  and
     is working with Sonex on securing  joint  commercialization  projects  with
     engine manufacturers.

**   This fall the Senate and House will resume debate on a national energy bill
     that upon  enactment  is  expected  to  include  provisions  assigning  the
     Department  of  Transportation  (DOT) the task of issuing new fuel  mileage
     standards  within  two years of  enactment.  In  response,  Sonex  plans to
     complete  development,  commercialize  and market its SCS Stratified Charge
     Radical  Ignition  (SCRI)  combustion  process to the automotive  industry.
     Presently,  high mileage  five-passenger  automobiles using gasoline direct
     injected  (GDI)  engines are sold in Japan and Europe but are not available
     in the U.S. due to high NOx (oxides of nitrogen)  emissions.  Sonex intends
     to demonstrate that SCS-SCRI can lead to high mileage, emissions compliant,
     GDI engined  vehicles  without  sacrificing  weight and vehicle safety.  In
     addition,  the evolution of U.S.  produced hybrid powered vehicles would be
     accelerated  since  a  major  improvement  in fuel  mileage  would  provide
     opportunities  for tradeoff of vehicle weight versus power. The anticipated
     passage of the national  energy bill will provide  Sonex the time needed to
     continue SCRI technology  maturation work for GDI engines.  To date,  Sonex
     has  provided  specific  input to the energy bill  legislative  process and
     submitted supporting data, industry analyses and other materials to DOT.

**   Additional  anticipated  contracts  to Sonex  from the  government  involve
     development  efforts that should provide  definitive  conclusions as to the
     commercial viability of the patented SCS technology for in-cylinder control
     of ignition and  combustion.  In  particular,  outcomes from these programs
     will be useful to the development of the SCRI  combustion  process for high
     mileage,  low  emissions  GDI  engined   automobiles.   Acceptance  of  our
     technology  by the  government  will  enable  Sonex to bring a third  party
     validation  to any  commercial  discussions  we may  undertake,  as well as
     critical data and test results that support  numerous  applications  of our
     technology.


Sonex is poised to leverage its proprietary  SCS technology  against the demands
of  government,  as they impact the  automotive  industry  and ongoing  military
innovation.  The Company is seeking  business  partners and strategic  alliances
that will help bring SCS to  commercialization.  The  Company  already has begun
adding to its technical staff to meet the demands of the recent subcontract from
SAIC, and will need to continue hiring as new contracts are secured.  Management
also  recognizes  that  commercialization  will require the hiring of additional
executives  with industry  experience.  While revenue is expected to increase as
new  contracts  are signed,  the Company may also need to raise capital to reach
its goals.

In  anticipation  of the contracts that have just begun to  materialize  and the
resulting expected change in the Company's profile in the automotive and defense
industries as well as the  investment  community,  in June 2002 Sonex  announced
that it had retained The  Scottsdale  Group (TSG) as its investor  relations and
financial   communications   consultant.   TSG  is   undertaking   a   financial
communications  campaign  that will bring  Sonex to the  attention  of a broader
investor base, as well as institutional  investors,  as the Company continues to
grow. In the coming months,  TSG will take our story to the media,  existing and
potential  investors,  and  specialists  who follow the  automotive  and defense
industries.  Sonex has  endured  serious  hardships  in the past  year,  but our
efforts  are  being  rewarded  in the form of the many  opportunities  described
above.  Thanks to the dedication  and hard work of our core personnel  group and
the timely financial support from investors, the Company is about to emerge from
one of the most trying  periods in its history.  Finally,  I extend my heartfelt
thanks to our  shareholders  for their  continued  patience and support.  I look
forward to this year's Annual Meeting and to receiving your input, questions and
comments.


                                 Sincerely,


                                 Andrew A. Pouring, D.Eng.
                                 Chief Executive Officer
