ITEM 5. - OTHER EVENTS

     On May 28, 2002, Sonex  Research, Inc. (the  "Company") posted the
following notice to shareholders on its website (www.sonexresearch.com):


                   COMPANY RESPONDS TO DECLINE IN STOCK PRICE;
                      CEO EXPRESSES CONFIDENCE IN PROSPECTS

Annapolis, Maryland
May 28, 2002

To the Shareholders of SONEX RESEARCH, INC. (OTC BB: SONX):

In light of the  sudden  decline in our stock  price at the end of last week,  I
wanted to inform  you that  there have been no recent  adverse  developments  at
Sonex and that management remains confident in the Company's prospects. In fact,
both our CFO,  George E.  Ponticas,  and I  acquired  more  Sonex  shares in the
Company's  most recent  private  financing at the end of March 2002,  and we are
continuing  to defer  payment of  significant  portions of our current  wages to
reduce the Company's cash flow requirements.

The Company has high expectations of being awarded a significant contract in the
near  future for SCS heavy fuel  engine  development.  Feedback to date has been
positive on our proposal for  conversion  of an  automotive  gasoline  engine to
operate on  diesel-type  heavy  fuel for  application  in a large UAV  (unmanned
aerial vehicle) for the military.

We also  believe the  prospects  are good for a potential  subcontract  award to
Sonex for an effort  relating to a vehicular  diesel  engine  application  being
developed  in  conjunction  with a  commercial  partner.  For  its  part in this
proposed  program,  Sonex  would  work  on a  state-of-the-art,  multi-cylinder,
automotive  diesel  engine to apply our SCRI  combustion  process.  A successful
result from this proposed government funded program would provide SCRI data on a
multi-cylinder diesel engine for presentation to any engine manufacturer without
being subject to the  confidentiality  restrictions that exist in our commercial
development programs.

This month the Company engaged the services of a professional investor relations
and financial communications firm to develop,  implement and maintain an ongoing
program to increase the investment  community's  awareness of Sonex  activities.
Shortly,  we will provide details on this new  relationship,  including  contact
information and a website address.

I remain very optimistic about the commercial prospects for the Sonex combustion
technologies.  The Company will continue to seek the  resources  and  commercial
partners necessary to complete development work.

I wish to thank our shareholders for your continued support and patience.


                           Very truly yours,


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

                            **********************
