                               SHAREHOLDER UPDATE

                                 November 2004


Dear Fellow Shareholders:

Sonex  Research,  Inc.  (OTCBB:  SONX)  will  hold its 2004  Annual  Meeting  of
Shareholders in Annapolis on Monday,  December 20, 2004. This Shareholder Update
is  being  provided  with  the  proxy  materials  for the  Annual  Meeting.  The
accompanying  Annual Report on Form 10-KSB for the year ended  December 31, 2003
provides a comprehensive  explanation of the Company's business  initiatives and
finances  as of April 2004 when the Form  10-KSB  was filed  with the SEC.  This
Shareholder Update brings us forward to the present, including a brief financial
overview  derived from our September 30, 2004  Quarterly  Report on Form 10-QSB.
The complete Annual Report,  Quarterly Report, and Proxy Statement as filed with
the SEC are  available  by  following  the link to SEC  Filings  provided in the
Investor Relations section of our website  www.sonexresearch.com.  The documents
on the SEC's  website are in plain text format and do not contain most  standard
document formatting  features.  You can request formatted versions directly from
the Company, either in electronic format or in hard copy.


CURRENT ENGINE PROGRAMS

In July 2004 the  Company  received a follow-on  task from the Defense  Advanced
Research  Projects  Agency (DARPA) to continue  development of a  multi-cylinder
"heavy fuel" engine (HFE) combustion process for potential Department of Defense
(DoD)  applications such as unmanned aerial vehicles (UAVs).  Under the existing
contract,  Sonex has adapted a lightweight gasoline automotive engine to a Sonex
Combustion System (SCS)  unthrottled,  direct fuel injection  combustion process
based on the Sonex  Controlled  Auto-Ignition  (SCAI)  technology to run on JP5,
military kerosene-based heavy fuel. The SCAI process is enabled by a proprietary
piston  technology  that achieves  in-cylinder  chemical  kinetics at a moderate
compression  ratio for auto ignition of the JP5. The laboratory HFE features the
proprietary Sonex pistons,  electronically controlled common rail fuel injection
system and extensive instrumentation.

The DARPA contract was extended to add a task to: enhance the 6-cylinder HFE for
higher power output; achieve boosted HFE combustion  optimization;  perform data
collection-analyses;  and  provide a  technical  readiness  demonstration.  This
project is  sponsored by DARPA as a technology  feasibility  demonstration  of a
means for lightweight  piston engines to comply with a DoD policy directive that
mandates  kerosene-based  "heavy"  fuel for all  engines.  Gasoline  engines are
typically 25% to 30% lighter than diesel engines; thus, fully qualified, adapted
gasoline engine designs that could burn low cetane (hard to ignite, diesel type)
heavy fuel would address DoD performance, logistics and safety requirements.

Achievement  of the technical  readiness  demonstration  is expected to form the
basis for  in-depth  discussions  with the major DoD prime  contractor  which is
building a UAV for DARPA that  requires  such a  high-powered  HFE. In addition,
outcomes from the DARPA program  could  validate the sparkless  SCAI process for
in-cylinder  control of ignition and combustion that could be applied later to a
gasoline  powered version for use in automobiles to achieve better fuel economy.
Sonex  also  believes  the   availability   of  the  resultant   multi-cylinder,
four-stroke HFE from a successful outcome of the DARPA project could lead to use
in other military engine  programs,  as well as having  potential for use in the
commercial  marine  market.  During  2004  the  Company  expanded  the  range of
lightweight,  spark-ignited,  two-stroke,  gasoline  engines  it  has  converted
successfully  to heavy fuel  operation  through  application of its SCS starting
system and modified combustion  chamber.  The Company seeks to capitalize on the
success to date with SCS HFEs by participation in new DoD programs, particularly
for smaller  UAVs,  whose  sponsors are obliged to make an effort to comply with
the directive on the elimination of gasoline as a battlefield fuel.

Under a Department of Energy (DOE) subcontract awarded late in 2002 by DOE prime
contractor  Compact Membrane Systems,  Inc. (CMS), Sonex undertook an evaluation
of the diesel engine emissions  reduction potential of combining the SCS and the
CMS polymer membrane  technology for the addition of nitrogen enriched air (NEA)
to the combustion process. Sonex conducted the testing on an advanced, research,
three-cylinder,  common rail direct injected,  turbo-charged,  automotive diesel
engine developed by a major international vehicle manufacturer in the joint U.S.
government and automotive industry funded PNGV (Partnership for a New Generation
Vehicle)   program.   Initial  testing   focused  on  the  emissions   reduction
capabilities  of the SCS Low Soot Diesel Design (LSDD)  pistons  without the NEA
membrane.

The  Company  was not able to achieve  the LSDD  performance  achieved  in other
engines with conventional  injection  systems.  Sonex encountered  difficulty in
controlling the characteristics of the common rail injection system and matching
its requirements with the design requirements of the SCS pistons,  which must be
compatible with the fuel injection system and computer  control.  Achieving this
synergy  proved to be very  challenging  since many  critical  parameters of the
engine baseline and electronic engine control unit (ECU) were not made available
to Sonex. In addition,  initial testing with the NEA membrane  demonstrated  the
limited viability for  commercialization of the CMS membranes in this automotive
size  application.  During the first quarter of 2004, CMS suspended further work
on the program.  Sonex  developed and presented in April 2004 to the DOE program
sponsor a plan to understand the  difference  between the common rail system and
earlier injection systems when used with LSDD pistons;  however, the DOE did not
reinstate the funding to Sonex.

Sonex will utilize the automotive  diesel engine as a laboratory asset and as an
LSDD  demonstrator.  To  overcome  the  difficulties  encountered  with  the ECU
provided,  Sonex has replaced it with a commercial  ECU and now has full control
of the common rail fuel injection system. This will allow demonstrating the full
capabilities  of the LSDD in this  engine and thereby  provide  SCS  in-cylinder
emissions  reduction  data on a modern  multi-cylinder  diesel engine for engine
manufacturers  to evaluate the  potential for SCS designs to reduce the cost and
complexity of future exhaust aftertreatment systems.


ORGANIZATIONAL CHANGES

During  2004 the  Company  experienced  a number of  significant  organizational
changes.  In February  following the resignation of its three outside directors,
who cited other business  responsibilities  as the reason for  resignation,  the
Board was  reconstituted and a new president was hired to fill the position that
had been vacant. The Company's new president, who was also named chief executive
officer  in July 2004,  was  brought  on to  develop,  raise  capital  for,  and
implement an updated  business plan, the primary goal of which was to transition
Sonex  from  a  research  and   development   company  into  a  technology   and
manufacturing enterprise. The Company, however, has been unable to date to raise
sufficient  capital to complete and  implement  this updated  business  plan. In
October 2004 the Company's new president and chief executive  officer  resigned,
and I took over those roles.

As a result of other recent changes in its  membership,  the Company's  Board of
Directors now consists of our chief  financial  officer,  George  Ponticas,  and
myself.  Our intention is to add to the Board one or more qualified  individuals
who have no current  affiliation with the Company towards a goal of constituting
a Board  with a majority  of  independent  directors.  In  addition,  we hope to
determine  the proper  course of action to move Sonex  forward.  The  Company is
pursuing new  opportunities  for revenue as  development  work  continues on the
current engine projects and is attempting to secure relationships with companies
which have technologies complementary to the Sonex processes.



FINANCIAL CONDITION AND RESULTS OF OPERATIONS

From the second  half of 2002  through  2003,  Sonex saw  substantial  growth in
revenue,  but we have been unable to maintain that momentum in 2004. We continue
to minimize disbursements through the voluntary deferral of current compensation
by Company officers,  flexible payment  arrangements  with consultants,  and the
securing  of  short-term  loans  from  shareholders.   The  Company's  long-term
viability,  however,  is  dependent  upon its ability to enter into  significant
funded contracts for the further development of its technology,  establish joint
ventures or strategic  partnerships with major industrial concerns,  or secure a
major capital  infusion.  There is no assurance  that we will be able to achieve
these objectives.  In the event sufficient funding is not available, the Company
would have to substantially reduce the level of its operations. Such a reduction
could  have a  material  adverse  effect  on the  Company's  relationships  with
government funding sources, strategic partners and potential customers.

The following are summary  figures for, and a brief  discussion  of,  results of
operations for the nine-month periods ended September 30, 2004 and 2003.

                                            ============     =============


Revenue  decreased  59% from the first  nine  months  of 2003 to the  comparable
period in 2004, as work wound down in 2004 on the two major government  projects
discussed previously which were awarded to the Company during the second half of
2002.  Combined  revenue from these two projects  decreased from $547,948 in the
first nine months of 2003 to $178,991 in the current period. With respect to the
first project,  in July 2004 the Company received a $192,932 follow-on task from
DARPA.  To date,  $88,591 of this total has been billed and  received,  while an
additional  $104,341  remains to be billed for work to be performed  through the
completion  of the  task.  Further  funding  for  the  second  project,  the DOE
subcontract, has been discontinued.

Total costs and expenses increased 64% from the first nine months of 2003 to the
comparable  period in 2004. A  significant  portion of the increase in costs and
expenses  resulted from the  organizational  changes undergone by the Company in
2004.

Cost of revenue  primarily  consists of direct  labor  charges and other  direct
expenditures, including those for technical consulting services, attributable to
funded programs, as well as allocated fringe benefits,  payroll taxes, and labor
overhead charges. While cost of revenue during the first nine months of 2003 was
67% of revenue,  in the first nine months of 2004 cost of revenue  substantially
exceeded  revenue,  primarily  due to  significant,  unanticipated  project cost
overruns  during  the  first  and  second  quarters  of 2004 and a higher  labor
overhead rate in 2004 versus 2003.

General and administrative (G&A) expenses consisted of the following amounts:

                                            ============     =============


Total G&A  expenses for the first nine months of 2004 more than tripled from the
comparable  period  in  the  prior  year,  largely  due to  substantial  charges
resulting  from  the  hiring  of a new  president  in  February  2004.  Employee
compensation  increased  by  $239,762  from  2003 to 2004,  as  charges  for the
compensation of the new president, who was also named chief executive officer in
July 2004,  totaled $220,052.  This figure includes amounts related to stock and
stock option compensation,  the award of a cash bonus for which payment is being
deferred  until 2006,  and  salary,  nearly 50% of which has been  deferred.  In
October 2004 the Company's new president and chief executive officer resigned.

Consulting  fees  increased  by  $333,449  from 2003 to 2004.  Charges  for 2004
include $262,500  associated with a consulting  agreement  effective in February
2004 for services to assist in the  transition  of the Company into a technology
and  manufacturing  enterprise  under the updated business plan being developed.
Such  charges  consist of $195,000  for the value of common  stock  issuable and
$67,500 for the estimated fair value of warrants to purchase common stock. Other
charges in 2004 totaling  $92,500,  including  $33,600  payable in common stock,
represent fees for various business advisory  services from individuals  engaged
by the Company's new president.

The  increase  in  professional  fees of  $127,964  from  2003 to 2004 is almost
entirely  due to a charge  in the  first  quarter  of 2004 for a  non-refundable
retainer  payable in stock valued at $120,000 to the  Company's  new  securities
legal  counsel in March 2004.  This firm  subsequently  invoiced  the Company an
additional  $102,000 for  services  rendered  through  June 30, 2004.  Sonex has
disputed the firm's entitlement to the fees claimed and is presently represented
by another  attorney on a pro bono basis in  connection  with this  matter.  The
Company has requested,  but has not received, an explanation of, and the billing
support  for,  the  amounts  invoiced  by this firm.  While the  outcome of this
dispute is uncertain and may have an adverse  effect on the Company's  financial
condition, we believe that the Company has a defensible position.


Closing

My belief in the SCS technology and the Company remains  steadfast.  I extend my
gratitude  to my fellow  shareholders  for their  continued  support  and to our
employees and consultants for their dedication and commitment. I look forward to
seeing many of you at the 2004 Annual  Meeting of  Shareholders  in Annapolis on
Monday, December 20, 2004.


                                   Sincerely,
