                              SONEX RESEARCH, INC
                     NOTES TO CONDENSED FINANCIAL STATEMENTS

                                   (Unaudited)


NOTE 1 - THE COMPANY

Sonex Research, Inc. has developed a proprietary technology,  known as the Sonex
Combustion  System  (SCS),  which  improves the  combustion  of fuel in internal
combustion  engines through  modification of the pistons in large engines or the
cylinder  heads  in small  engines.  The SCS  achieves  in-cylinder  control  of
ignition and  combustion  to increase fuel mileage of gasoline  engines,  reduce
emissions of diesel engines,  and permit small gasoline  engines to run on safer
diesel-type  fuels. The Company's  objective is to execute broad agreements with
engine and parts manufacturers for industrial production of SCS components under
license from Sonex.


NOTE 2 - PRESENTATION OF FINANCIAL STATEMENTS

The accompanying  unaudited condensed financial statements have been prepared in
accordance with accounting principles generally accepted in the United States of
America for interim  financial  information  and with the  instructions  to Form
10-QSB  and  Item  310(b)  of  Regulation  S-B.  Accordingly,   these  financial
statements  do not  include all of the  information  and  footnotes  required by
generally accepted accounting principles for complete financial  statements.  In
the opinion of  management,  all  adjustments  (consisting  of normal  recurring
accruals) considered necessary for a fair presentation have been included.

Operating results for the three- and nine-month periods ended September 30, 2003
are not necessarily  indicative of the results that may be expected for the year
ending  December 31,  2003.  For further  information,  reference is made to the
financial  statements and notes thereto  included in the Company's Annual Report
on Form 10-KSB for the year ended December 31, 2002.

Certain  reclassifications  have been made to the  financial  statements  of the
prior year to conform to the  classifications  used in 2003,  most  notably  the
reclassification  of amounts in the  Statement of  Operations  from Research and
Development to Cost of Revenue.

The  costs  associated  with the  filing of patent  applications  are  deferred.
Amortization is recorded on a straight-line  basis over the remaining legal life
of patents, commencing in the year in which the patent is granted. Costs related
to patent applications which ultimately fail to result in the grant of a patent,
as well as the unamortized costs of patents abandoned by the Company due to lack
of expected  commercial  potential,  are charged to  operations at the time such
determination is made.

All of the Company's revenue for 2002 and 2003 has been derived from development
and  demonstration  contracts issued by a United States Government or Department
of Defense (the "Government") agency or prime contractor.  Revenue is recognized
upon the Company's  completion of the milestones  and/or  submission of progress
reports  specified in each contract.  Revenue and costs for these contracts that
require the Company to provide  stipulated  services for a fixed price have been
recognized using the  percentage-of-completion  method of accounting by relating
contract costs incurred to date to total estimated contract costs at completion.
In  connection  with  contracts in progress,  any excess of billings  over costs
incurred plus estimated  profits is recorded as a current  liability,  while any
excess of costs  incurred over billings is recorded as a current  asset,  at the
financial statement date.

For  fiscal  year  2003,  the  Company  changed  its  method of  accounting  for
stock-based compensation, as described in Note 8.


NOTE 3 - LIQUIDITY

Management  recognizes that the Company's history of operating losses,  level of
available funds, and revenue from current and future  contracts,  in relation to
projected  expenditures,  raise substantial doubt as to the Company's ability to
commence generation of significant  revenues from the  commercialization  of the
SCS and ultimately achieve profitable operations.  Accordingly, the Company will
continue to minimize its  operating  expenditures  through a number of measures,
including the ongoing  deferral by its officers of portions of their salaries as
described in Notes 5 and 6.

Based upon  available  resources,  current and projected  spending  levels,  and
expected revenue from current and anticipated contracts, management believes the
Company will have sufficient  capital to fund operations through March 31, 2004.
The Company's prospects beyond that date are dependent upon its ability to enter
into  significant  funded  contracts  for  the  further  development  of its SCS
technology,  establish  joint  ventures  or  strategic  partnerships  with major
industrial concerns,  or secure a major capital infusion.  There is no assurance
that the Company  will be able to achieve  these  objectives;  therefore,  there
remains  substantial  doubt about the  Company's  ability to continue as a going
concern.


NOTE 4 - DEBT

Short-term lines of credit

In March 2003 the Company  obtained a business credit card from Capital One Bank
with a credit  limit of $20,000 to  facilitate  the  purchase of  equipment  and
materials.  Repayment  of  amounts  due has been  personally  guaranteed  by the
Company's chief executive  officer.  Balances accrue interest at a fixed rate of
8.9% per annum. As of September 30, 2003, the outstanding  balance on the credit
card account was $17,750.

In October 2003 the Company  refinanced  $18,050 then outstanding on this credit
card by  transferring  the  balance  to a new  business  credit  card from Fleet
National Bank.  Repayment of amounts due on this credit card, which has a credit
limit of $19,000,  also has been  personally  guaranteed by the Company's  chief
executive  officer.  The account has a  promotional  interest rate of 0% through
June 2004, adjusting to prime rate + 6% thereafter.

The account  with  Capital  One Bank  remains  open and the credit line  remains
available for use by the Company if needed.


Capital Lease Obligations

During the first quarter of 2003 the Company incurred capital lease  obligations
totaling $43,002 in connection with the acquisition of equipment.  The repayment
of a four-year  equipment  lease  obligation in the principal  amount of $38,575
included in this total has been  personally  guaranteed by the  Company's  chief
executive officer.  As of September 30, 2003, the outstanding  principal balance
on this lease obligation was $32,212.


Notes Payable to Shareholder

In  connection  with a private  financing  in March 2002,  the Company  issued a
$6,000, 6% note to one of its shareholders,  initially payable on June 30, 2002,
that is convertible  to equity at the option of the holder.  The due date of the
note has been extended  several times and is currently due on December 31, 2003.
In July 2002 the  Company  issued a  $30,000,  8% note to this same  shareholder
payable  initially  on  January  31,  2003.  The due date of the  note  also was
extended to September 30, 2003.  The Company  issued a $50,000,  6% note in June
2003 to this same shareholder payable on December 31, 2003. Payment of all three
notes is secured by Company revenues.

In July 2003 the Company paid the July 2002,  8%,  $30,000 note in full, as well
as all remaining interest on the note.


NOTE 5 - ACCRUED COMPENSATION AND BENEFITS

Accrued compensation and benefits consists of the following amounts:


                                                 Sept. 30,        December 31,
                                                    2003              2002
                                                -----------       -----------

    Accrued wages and payroll taxes             $   273,900       $   235,515
    Accrued consulting fees                          58,945            31,737
    Accrued bonuses                                  97,576            95,499
    Accrued vacation pay                             51,661            64,646
                                                -----------       -----------
                                                $   482,082       $   427,397
                                                ===========       ===========

The Company  operated under severe cash flow  difficulties  for extended periods
during 2001 and 2002, prompting its two officers to voluntarily and at their own
discretion  defer  receipt of payment of  significant  portions of their current
wages to reduce the Company's monthly cash requirements.  With the generation of
cash flow from revenues earned under contracts awarded to the Company during the
second half of 2002,  some of the amounts owed to the  Company's  officers  were
repaid  in  December  2002.  Also at that  time  the  Company's  officers  began
receiving  their current  wages.  During the first quarter of 2003 the Company's
chief  executive  officer once again began  deferring  some of his current wages
and, since April 2003, he has deferred all of his current wages. As of September
30, 2003,  total such wages payable to the Company's  chief  executive and chief
financial officers were $166,597 and $86,403, respectively.

The continued  deferral of portions of current  wages by the Company's  officers
cannot be expected to continue indefinitely, and the Company will be required to
pay amounts outstanding as soon as cash flow permits. Similarly, the Company has
accumulated unpaid consulting fees, the majority of which amounts are payable to
the individual who serves as the Company's director of business  development and
technical  program manager on a part-time  basis. As of September 30, 2003, this
individual  is owed  $41,175.  The  amount  and  timing of  payments  for unpaid
compensation  owing  to the  Company's  officers  and  this  consultant  will be
determined at the discretion of the Company's officers; however, all such unpaid
compensation  is payable  upon demand,  as these  amounts are not subject to the
terms of the Company's  written  agreement with current and former  personnel to
defer payment of portions of their compensation as described in Note 6.

In  December  of each year,  the  Company  awards  bonuses to its  officers  and
employees  with the  stipulation  that payment of such bonuses is to be deferred
until the Board of Directors  determines  that the Company's  cash resources are
sufficient to enable such payments.  In connection  with a private  placement in
March 2002 as detailed in Note 8, the Company paid $22,500 of bonuses accrued as
of  December  31,  2001 and $4,500 of  consulting  fees  accrued as of that date
through the conversion of such amounts to equity.  The amount of accrued bonuses
included  in the table  above that was  payable  to the  Company's  officers  at
September 30, 2003 is $72,500. Payment of accrued bonuses are not subject to the
terms of the Company's  written  agreement with current and former  personnel to
defer payment of portions of their compensation as described in Note 6.

The Company's only liability to employees for future compensated absences is for
accrued but unused  vacation pay. The amount of vacation pay earned by employees
is determined by job classification and length of service. The amount of accrued
vacation included in the table above that was payable to the Company's  officers
at September 30, 2003 is $47,635.  Accrued vacation compensation is payable upon
termination of employment, and such payments are not subject to the terms of the
Company's  written  agreement with current and former personnel to defer payment
of portions of their compensation as described in Note 6.


NOTE 6 - DEFERRED COMPENSATION

In order to help  conserve  the  Company's  limited cash  resources,  all of the
Company's  current  and  former  officers  and  certain of the  Company's  other
employees and consultants for several years have voluntarily deferred receipt of
payment of significant portions of their authorized  compensation at the request
of the Board of Directors. A written agreement between these individuals and the
Company  was first  executed  in 1992 in  connection  with an  indispensable  $2
million  private  investment made by a venture capital group in exchange for the
issuance of a new class of convertible  preferred  stock as described in Note 8.
The  individuals  who  are  parties  to this  agreement  have  consented  to the
continued deferral,  as necessary,  of current  compensation and the deferral of
payment of amounts so  accumulated  until the  Company  has  received  licensing
revenue of at least $2 million or at such earlier date as the Board of Directors
determines that the Company's cash flow is sufficient to allow such payment.

Deferred compensation outstanding is payable to the following classifications of
personnel:


                                                 Sept. 30,        December 31,
                                                    2003              2002
                                                -----------       -----------

    Current officers                            $   623,576       $   574,249
    Current employees                                12,504            12,504
    Former officers, employees and consultants      320,103           320,103
                                                -----------       -----------

                                                $   956,183       $   906,856
                                                ===========       ===========

The amount reported above for deferred  compensation payable to current officers
consists  of  $476,327  payable to the  Company's  chief  executive  officer and
$147,249 payable to its chief financial officer.

The  conditions  that would  require  repayment of deferred  amounts have yet to
occur, and it is unlikely that such conditions will occur prior to September 30,
2004.  Accordingly,  such deferred  compensation  is reported  separately in the
accompanying balance sheet as a non-current liability.

At the  conclusion  of a legal  challenge by two former  officers of the Company
initiated  in  1993  demanding  full  payment  of  deferred  salaries  upon  the
termination of their  employment,  in 1996 the Maryland Court of Special Appeals
rejected this demand and ruled that the written agreement to defer  compensation
was a valid and enforceable contract.


NOTE 7 - INCOME TAXES

The  Company  has not  incurred  any  federal or state  income  taxes  since its
inception  due to operating  losses.  At December 31, 2002,  the Company had net
operating loss and capital loss  carryforwards  of  approximately  $12.5 million
available to offset future taxable income. If certain substantial changes in the
Company's  ownership  should occur,  there would be an annual  limitation on the
amount of the carryforwards which can be utilized. Since 1995 net operating loss
carryforwards  aggregating  approximately  $6.6 million have expired unused,  as
have capital loss  carryforwards of approximately  $335,000.  Net operating loss
carryforwards  of  approximately  $1,345,000 and capital loss  carryforwards  of
approximately $365,000 are scheduled to expire at the end of 2003.


NOTE 8 - CAPITAL STOCK

Authorized capital stock

The Company is presently authorized to issue 48 million shares of $.01 par value
common stock and 2 million shares of $.01 par value convertible preferred stock.
All of the  authorized  shares of  preferred  stock,  along  with  common  stock
purchase warrants,  were issued in connection with an indispensable financing of
$2 million received in February 1992 (the "Preferred Stock  Investment")  from a
small number of individuals who qualified as "accredited  investors" pursuant to
Rule 501 of  Regulation  D of the  Securities  Act of 1933  (the  "Act")  and to
Proactive Partners, L.P. and certain of its affiliates ("Proactive"), who became
the largest  beneficial  owner of the  Company's  common  stock by virtue of the
acquisition  of the  convertible  preferred  stock  and  common  stock  purchase
warrants.

The preferred  stock has priority in liquidation  over the common stock,  but it
carries no stated  dividend.  The holders of the  preferred  stock,  voting as a
separate class,  have the right to elect that number of directors of the Company
which  represents a majority of the total  number of  directors.  The  preferred
stock is  convertible  at any time at the option of the holder into common stock
at the rate of $.35 per share of common stock. As of September 30, 2003, a total
of 459,999 shares of preferred stock had been converted into 1,314,278 shares of
common stock.


Private placement of common equity

In a private  financing at the end of March 2002,  the Company raised capital of
$60,000,  including $27,000 in cash investments,  $27,000 from the conversion to
equity of accrued liabilities to officers,  employees and consultants,  and cash
proceeds of $6,000 through the issuance of a short-term note that is convertible
to  equity  at the  option  of the  holder.  A total of  360,000  shares  of the
Company's common stock and five-year  warrants to purchase an additional 180,000
shares of common  stock at $.25 per share  were  issued in this  financing,  and
60,000 shares were reserved for future  issuance upon the conversion of the note
payable to common stock and a warrant to purchase common stock.

The offer and sale of these  shares of common  stock and  warrants  to  purchase
shares of common stock  satisfied the  conditions of Rule 506 of Regulation D of
the Act and, as such, were exempt from the registration  requirements of Section
5 of the Act as  transactions  not  involving  any  public  offering  within the
meaning of Section 4(2) of the Act.


Stock options

The Company  maintains a non-qualified  stock option plan (the "Plan") which has
made available for issuance a total of 7.5 million  shares of common stock.  All
directors,  full-time  employees and consultants to the Company are eligible for
participation.  Option awards are  determined at the  discretion of the Board of
Directors.  Upon a change in control of the  Company,  all  outstanding  options
granted to employees and  directors  become vested with respect to those options
which have not  already  vested.  Options  outstanding  expire at various  dates
through June 2013. From January 1, 2003 through  September 30, 2003, the Company
had the following  activity in options to purchase  shares of common stock under
the Plan:


                                            Weighted                Weighted

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

Through  December 31, 2002, the Company  accounted for stock-based  compensation
using the intrinsic value method prescribed in Accounting Principles Board (APB)
Opinion No. 25. Under APB No. 25,  compensation  cost is measured as the excess,
if any, of the quoted market price of the  Company's  stock at the date of grant
over the  exercise  price of the  option  granted.  Compensation  cost for stock
options, if any, is recognized ratably over the vesting period.

As of January 1, 2003,  the Company  adopted  Statement of Financial  Accounting
Standards  (SFAS) No. 123 - "Accounting  for  Stock-based  Compensation",  which
provides  for the fair value  based  method of  accounting  to be applied to the
Company's stock option grants and other stock-based compensation. SFAS No. 148 -
"Accounting for Stock-based  Compensation Transition and Disclosure",  issued in
December 2002, amends SFAS No. 123 to provide  alternative methods of transition
for a voluntary  change to the fair value based method of  accounting  for stock
options and other stock-based employee  compensation.  The Company has chosen to
apply the "modified  prospective  method" of SFAS No. 148 pursuant to which fair
value based stock option  compensation  costs for 2003 will be  recognized as if
the  fair  value  based  method  had  been  used to  account  for  all  employee
stock-based awards made in prior periods as well as the current period.

For purposes of  calculating  charges to expense for stock  option  compensation
under SFAS No. 123, the Company has  estimated the grant date fair value of each
option using the Black-Scholes  option pricing model with the following weighted
average  assumptions  for  2003:  volatility  factor of 95%,  average  risk-free
interest rate of 3.8%, zero dividend yield,  and average  expected term of eight
years.  As a result,  for the nine months ended  September 30, 2003, the Company
recorded stock option  compensation under SFAS No. 123 totaling $65,670 based on
a weighted  average fair value per share for options granted during 2003,  2002,
2001,  and 2000 of $.17,  $.15,  $.19, and $.37,  respectively.  As was the case
under APB Opinion No. 25, the amount of compensation expense is also credited to
additional paid-in capital.

Had  compensation  cost for options  granted been  determined  in prior  periods
consistent  with the method of SFAS No.  123,  the Company  would have  recorded
additional  compensation  expense of $97,899  for the first nine months of 2002,
and the  Company's  net loss and net loss per  share for the nine  months  ended
September 30, 2002 on a pro forma basis would have been as follows:


    Net loss - as reported                      $270,303
    Net loss - pro forma                        $368,202

    Net loss per share - as reported               $.012
    Net loss per share - pro forma                 $.017


The  Black-Scholes  valuation model was developed for use in estimating the fair
value of  traded  options  which  have no  vesting  restrictions  and are  fully
transferable,  as opposed  to the type of  compensatory  options  granted by the
Company.  It also requires the input of highly subjective  assumptions,  such as
the expected stock price volatility,  changes in which can materially affect the
fair  value   estimate.   Because  the  options  granted  by  the  Company  have
characteristics  significantly  different  from  those of  traded  options,  the
amounts  calculated  using the Black  Scholes  option  valuation  model,  in the
opinion of management,  do not necessarily  provide a reliable single measure of

NOTE 9 - COMMITMENTS

The Company  occupies  its office and  laboratory  facility on a  month-to-month
basis  under the terms of an  operating  lease  agreement  pursuant to which the
property owner is required to provide thirty days notice if he wants the Company
to vacate the premises.  The lease currently provides for monthly rent of $4,000
and requires the Company to pay all property related expenses.  The Company will
seek to  negotiate  a new  long-term  lease for its  facility  or search  for an
alternative  location in the event that a long-term  agreement cannot be reached
for the  existing  premises.  Management  believes  that the  resolution  of the
uncertainty  with  respect  to the  facility  will not  result in a  significant
interruption in the operations of the Company.




ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL POSITION
                         AND RESULTS OF OPERATIONS


Caution regarding forward-looking statements

Sections of this document,  as well as all publicly  disseminated material about
Sonex Research, Inc. ("Sonex" or the "Company"), contain expressions of beliefs,
expectations, or intentions, in the form of "forward-looking" statements as that
term is defined under  applicable  federal  securities laws. Such statements are
based  on  current  expectations,  estimates,  projections  and  assumptions  by
management with respect to, among other things,  trends  affecting the Company's
financial  condition  or results of  operations  and the impact of  competition.
Words  such  as  "expects",  "anticipates",  "plans",  "believes",  "estimates",
variations of such words, and similar  expressions are intended to identify such
statements  that  include,  but are not limited  to,  projections  of  revenues,
earnings,  cash flows and contract awards. Such  forward-looking  statements are
not guarantees of future performance and involve risks and uncertainties, all of
which are  difficult  to predict and many of which are beyond the control of the
Company.

Forward-looking  statements  contained  herein speak only as of the date of this
report.  The Company  disclaims any  obligation to update these  statements  and
cautions readers not to place undue reliance on such statements.


Risk factors

In order to obtain the benefits of the "safe harbor" provisions under applicable
federal  securities  laws  for  any  "forward-looking"  statements  of the  type
described  previously  under  the  heading  "Caution  Regarding  Forward-Looking
Statements",  the  Company  cautions  shareholders,  investors  and  prospective
investors  about  significant  factors which,  among other things,  have in some
cases  affected the  Company's  actual  results and are in the future  likely to
affect the Company's  actual  results and cause them to differ  materially  from
those expressed in any such forward-looking statements.

Factors  that could  cause  actual  results  to differ  materially  include  the
specific risks listed below. These risks and uncertainties are not the only ones
faced by the Company or that may adversely  affect its  business.  If any of the
following  risks  or  uncertainties  actually  occur,  the  Company's  business,
financial  condition  or results of  operations  could be  materially  adversely
affected.

   o  ability  to  generate  cash flow from  revenue  or to secure  financing
      necessary  to fund future  operations
   o  ability to  complete  technology development and demonstration programs,
      demonstrate commercial viability of its technology and execute licensing
      agreements that produce significant  revenue
   o  ability to maintain and protect the Company's patents  and  proprietary
      information
   o  ability to attract and retain skilled  personnel
   o  ability to secure a long-term lease for the Company's existing facility
      or to secure an alternative location
   o  changes in general economic conditions
   o  competition from companies which have  substantially  greater financial,
      technical and marketing resources than does the Company

Furthermore,  since its inception in 1980, the Company has generated  cumulative
net losses of  approximately  $23 million,  and may continue to incur  quarterly
operating losses for the foreseeable  future.  Operating results have fluctuated
significantly  in the past on an annual and quarterly basis, and are expected to
continue to fluctuate  significantly from quarter to quarter for the foreseeable
future. The business historically has not generated sufficient cash flow to fund
operations  without  resorting to external sources of capital.  The Company does
not have any bank  financing  arrangements.  Operating  funds  have been  raised
primarily  through  the sale of equity  securities  in both  public and  private
offerings,  although revenues are now providing most of the necessary  operating
cash.

In the event that funding from  internal and external  sources is  insufficient,
the Company would have to cut back  significantly  its level of spending,  which
could  substantially  curtail the Company's  operations.  These reductions could
have an adverse effect on the Company's  relations with its potential  customers
and government funding sponsors.

The Company's success also depends in significant part on the continued services
of its key technical  and senior  management  personnel.  Losing one or more key
employees,  including for reasons of poor health,  disability,  or death,  could
have a material adverse effect on the Company's business, results of operations,
and  financial  condition.  Due to the expense  involved,  the Company  does not
maintain life  insurance  policies for any of its  employees.  Additionally,  in
order  to avoid  long-term  financial  commitments,  the  Company  does not have
employment agreements with any of its personnel.

Further,  the market  price of the  Company's  Common  Stock  could be  affected
adversely by the substantial  number of shares that are reserved for, and may be
issued in, the future. As of September 30, 2003, there were 21,592,669 shares of
Common  Stock  issued and  outstanding,  with an  additional  11,516,832  shares
reserved  for future  issuance  upon the  conversion  of  preferred  stock,  the
exercise of options and warrants, and the conversion of notes payable.


Competition

The  Company  faces   significant   competition  from  the  extensive   research
departments  of the  world's  major  vehicle  and  engine  manufacturers.  These
companies  exercise a bias toward in-house  technologies over those developed by
independent  suppliers.  Competition also comes from several  independent engine
testing  and  consulting  firms  around the world  which are in the  business of
developing engine  technologies.  The Company's  competitors have  substantially
greater  financial,  technical  and marketing  resources  than does the Company.
Accordingly,  the  Company  cannot be sure that it will  have the  resources  or
expertise to compete successfully in the future.

Although the experience and financial  resources of its  competitors  far exceed
those of the Company,  management  believes that the SCS can provide significant
advantages over the competition in terms of low cost, improved performance,  and
simplicity.


Secrecy and non-disclosure

Due to the  highly  competitive  nature  of the  world's  automotive  and  truck
industries,  in connection with its contracts and/or demonstration programs with
such  manufacturers,  Sonex is required to execute joint secrecy and  disclosure
agreements that, in most cases,  expressly prohibit the public disclosure of the
names and other  significant  information about the participants and the current
or  proposed  programs.  Failure  by  Sonex to  maintain  this  strict  level of
confidentiality would jeopardize its relationship with these organizations.

The same is true  with  respect  to the  Company's  relationships  with the U.S.
Department of Defense  (DoD) and its prime  contractors.  In many  instances the
Company is  contractually  prohibited  from  disclosing the name of the military
customer  and/or  specific   details  about  the  work  being  performed  unless
permission has been obtained from the customer in advance.


Overview of the Company and its technology

Sonex,  incorporated  in  Maryland  in  1980,  is an  engineering  research  and
development  firm that is  seeking to  commercialize  its  patented  proprietary
technology  (the  "Sonex  Combustion  System",  "SCS"  or  "Ultra  Clean  BurnTM
technology")  for  in-cylinder  control of ignition and combustion in engines of
various types.  The Company was  co-founded in 1980 by Dr. Andrew A. Pouring,  a
former  Professor of Aerospace  Engineering  and Chairman of the  Department  of
Aerospace Engineering at the U.S. Naval Academy. At Sonex, Dr. Pouring conducted
basic  research  into the  principle  of  in-cylinder  control of  ignition  and
combustion,  concentrating  on the piston.  By the late 1980's and early 1990's,
the  development  of the SCS had moved in the  direction  of  chemical/turbulent
enhancement of combustion  through  investigation of the effects of changing the
chemical  characteristics  and  fuel  disbursement  characteristics  within  the
combustion chamber.

The Company seeks to commercialize  its SCS technologies for a variety of engine
applications  for  commercial  and military  use. To date,  Sonex has engaged in
development and demonstration programs with the engine industry and has received
funding  from  the  federal  government  for  further  development  of  the  SCS
technologies.  The Company's  primary  objective is to execute broad  agreements
with engine and parts manufacturers for industrial  production of SCS components
under license from Sonex.

The SCS  technology  for  in-cylinder  control of  ignition  and  combustion  is
designed to

       o  reduce emissions of diesel engines
       o  increase fuel mileage of a new  generation of gasoline  engines
       o  permit gasoline engines to run on safer, kerosene-based "heavy" fuels

The SCS improves the combustion of fuels in engines through design  modification
of the pistons in  four-stroke,  direct  injected (DI),  engines or the cylinder
heads  in  two-stroke,   spark-ignited   (SI),   gasoline   engines  to  achieve
chemical/turbulent  enhancement of combustion. The SCS process for both two- and
four-stroke  engines  achieves  in-cylinder  control of ignition and  combustion
through the chemical/turbulent  enhancement of combustion via combustion chamber
modifications  that change the chemical  characteristics  and fuel  disbursement
characteristics within the combustion chamber.

SCS  reductions  of soot in DI diesel truck  engines  have been  confirmed by an
independent  international  engine  consulting firm.  Evidence to date indicates
that the SCS is a significant new engine design  variable,  and that the synergy
of the SCS in combination with exhaust gas  recirculation  (EGR) can help reduce
exhaust  aftertreatment  requirements to meet future regulatory  standards.  The
Company believes that SCS diesel engine designs should provide reductions in the
cost and complexity of future exhaust aftertreatment systems.

Sonex also is seeking to show the  technical  feasibility  of achieving  reduced
fuel consumption while lowering emissions in a new class of DI gasoline engines,
yet overcoming the safety concern that vehicles would need to be reduced in size
and weight to improve  fuel  mileage.  A new branch of the SCS  focusing  on the
control of ignition may, with further  development,  enable DI gasoline  engined
automobiles,  currently  manufactured  and sold only in markets outside the U.S.
due to emissions considerations, to become emissions compliant in the U.S. while
providing  fuel  consumption  benefits.  In  addition,  the  evolution of hybrid
gasoline  and  electric  powered  vehicles  could be  accelerated  since a major
improvement in engine fuel mileage would provide  opportunities  for tradeoff of
vehicle weight versus power.

An SCS process for the  conversion  of reliable,  lightweight,  SI,  two-stroke,
gasoline engines to start and operate on  kerosene-based  "heavy" fuels has been
applied  successfully  in a variety  of  applications  such as  small,  remotely
controlled  military unmanned aerial vehicles (UAVs).  The military now requires
such  engines  to  operate  on less  volatile  heavy  fuels to reduce the hazard
associated  with  gasoline,  making heavy fuel engines  (HFEs) more suitable for
applications   where  gasoline  storage  and  use  are  undesirable.   Potential
applications of the SCS heavy fuel conversion process can be expanded to a range
of military  and  commercial  uses.  Sonex is also  developing a process for the
heavy fuel conversion of SI four-stroke gasoline engines, and has recently begun
investigating  the synergy of SCS technology with rotary  engines.  In addition,
Sonex is examining the potential, through cooperation with one or more companies
which have complementary technologies and production capabilities, of becoming a
supplier of small HFEs to military and commercial markets.

As of November 15, 2003,  the Company has seven  full-time  and three  part-time
employees,  and engages the part-time services of a consultant who serves as its
director of business  development  and technical  program  manager on government
contracts.  The Company also engages the services of several other technical and
business  consultants as needed.  The Company has never  experienced a strike or
work stoppage, and believes its relations with its employees are good.


Strategic planning

The Company has come to realize that it lacks the  resources  to address  issues
such as piston manufacturing  processes,  durability testing, and cost analysis.
Present  Sonex  technology  development  is being  supported by U.S.  Government
funding, and the Company is also seeking committed business partners for further
technical  development  and  marketing  of the various SCS engine  applications.
Sonex believes that having one or more such partners experienced in dealing with
the  engine  and  automotive   industries  on   state-of-the-art   technological
developments  may  accelerate  commercial  acceptance  of  the  SCS  technology.
Development  efforts taking place currently under government  contracts to Sonex
could  facilitate  participation  by the engine and  automotive  industries  and
thereby  accelerate  commercialization  potential of the patented SCS technology
for  in-cylinder  control of ignition and combustion.  The Company  currently is
developing  a  marketing   strategy   targeting  the  most  immediate   business
opportunity - the government sector, the success of which is expected to enhance
marketing and commercialization efforts with industry.

In January 2003 the Company  engaged the Annapolis,  Maryland  consulting  group
Paradigm Technologies, LLC ("Paradigm") to assess the Company's technologies and
business  model and suggest  approaches  for strategic  alliances and additional
market introductions for both commercial and military  applications.  Presently,
Company management and Paradigm are pursuing a number of initiatives. One of the
first  goals is to secure  cooperation  with one or more  companies  which  have
technologies complementary to the Sonex processes.  Additionally,  Paradigm will
also seek  further  funding  for Sonex to conduct  technology  development  work
necessary for addressing  commercialization issues. The Company has also engaged
the services of The Washington Capitol Group (TWCG), a government  relations and
public  affairs firm in  Washington,  D.C.,  which also  specializes  in federal
marketing, government procurement assistance, and commercialization services.

The Company's  Board of Directors  and  management  will assess other  strategic
alternatives,  which may  include a sale of part or all of the  Company or other
corporate  transactions,  to permit Sonex shareholders to maximize the return on
their investments.


Primary SCS design modifications

The SCS technology for four-stroke DI engines improves the process of combustion
through a  combination  of  chemical  and fluid  dynamic  effects  that occur by
modifying the engine's  combustion  chamber and the processes  occurring  within
that  chamber.  The SCS  processes  for DI engines  change only a single  engine
component (the piston) while introducing no additional parts and are self-driven
by the combustion  process.  Patented SCS piston designs for four-stroke engines
integrate  cavities  called  micro-chambers  (MCs)  which form a ring around the
piston bowl,  with each MC  positioned  with respect to each spray from the fuel
injector of a DI engine.  The MCs are  designed  to function  either as chemical
reactors  or  reservoirs,  depending  on the  specific  design  needs,  and  are
connected to the piston bowl by vents. For soot reduction,  the reservoirs/vents
are placed to increase  turbulence,  while for enhanced ignition the MCs produce
highly active  chemical  species from a fraction of the fuel-air charge that are
expelled on the intake  stroke of low  compression  ratio DI engines to fumigate
incoming air and serve as an ignition source.

The SCS process for the  conversion of  lightweight,  SI,  two-stroke,  gasoline
engines introduces  patented features which enable the combustion of heavy fuels
through  design  modification  of the  cylinder  heads to  achieve a  chemically
enhanced  combustion  process  while  still  relying  on the  spark to  initiate
combustion.  Sonex uses a machined  cylinder head and combustion  chamber insert
housing the proprietary SCS technology, and a glow plug-based fuel vaporizer for
cold  starting.  For engines  that have the  cylinder  head and  cylinder in one
single  casting,  the stock cylinder head is removed and the remaining  cylinder
casting is decked and  machined for  cylinder  head  screws.  The SCS heavy fuel
conversion  maintains the gasoline  engine's stock carburetion or fuel injection
system, intake and exhaust systems, spark ignition system, compression ratio and
weight. The SCS starting system uses  commercial-off-the-shelf 12V glow plugs to
directly  vaporize  the heavy fuel for cold  starting.  Once the engine has been
started, the starting system is disabled.


Current funded projects

The Company seeks to commercialize  its SCS technologies for a variety of engine
applications  for  commercial  and military  use. To date,  Sonex has engaged in
development and demonstration programs with the engine industry and has received
funding  from  the  federal  government  for  further  development  of  the  SCS
technologies.  The  next few  paragraphs  provide  an  overview  of the  primary
initiatives taking place at Sonex.  Additional detailed information can be found
in the Company's December 31, 2002 Annual Report on Form 10-KSB.


                                   DARPA

In the fourth quarter of 2002 the Company was awarded a $744,246 contract by the
U.S. Defense Advanced  Research  Projects Agency (DARPA) to begin the design and
development of a heavy fuel conversion process for a gasoline  automotive engine
for potential use in a developmental unmanned aerial vehicle (UAV). This project
focuses on the SCS Sonex Controlled Auto Ignition (SCAI) combustion  process, an
unthrottled,  low compression ratio, sparkless,  compression ignition process at
gasoline  compression  ratios.  (Sonex  previously  referred to this  process as
Stratified Charge,  Radical Ignition - SCRI.) The primary objective of the DARPA
program is to  transfer  the SCS SCAI heavy fuel  design  achieved  in the Sonex
single-cylinder laboratory engine to a modern six-cylinder,  gasoline automotive
engine,  eliminate  the spark  ignition  system,  and produce the same power the
engine  originally  produced on gasoline.  As of November  15,  2003,  Sonex has
completed  the  laboratory  configuration  SCS  HFE  and  has  achieved  initial
operation  on heavy fuel over a limited  operating  range.  The Company will now
conduct  iterative  testing  to reach a final SCS  piston  design for heavy fuel
operation over the complete engine range. Completion of this project is expected
in early 2004.

The  Company  believes  the   availability  of  the  resultant   multi-cylinder,
four-stroke  heavy fuel engine from a  successful  outcome of the DARPA  project
could lead to use in other military  engine  programs such as small power boats,
as well as having potential for use in the commercial  marine market in pleasure
boats for  which a diesel  fueled  engine  would be a safer  alternative  to the
current gasoline  engines which too often result in dangerous  onboard fires. In
addition,  results from the DARPA  project  could be applied later to a gasoline
powered version to achieve  automotive engines with reduced fuel consumption and
emissions.  The time required to achieve technical  feasibility could be reduced
since the sparkless SCAI process can advantageously employ the centrally located
spark  plug  hole  of most  production  4-valve  per  cylinder  engines  for the
installation of the injector.


                                    DOE

In the fourth  quarter of 2002 the Company  received a subcontract  from Compact
Membrane  Systems,  Inc.  (CMS) for $458,862,  of which  $100,000 is cost-shared
(funded) by Sonex.  CMS is a prime  contractor  for a U.S.  Department of Energy
(DOE),  Small Business  Innovation  Research (SBIR)  Program,  Phase II project.
Sonex and CMS are evaluating the diesel engine emissions  reduction potential of
combining the patented piston-based, SCS technology and the CMS polymer membrane
technology  for the addition of nitrogen  enriched  air (NEA) to the  combustion
process.  In the second  quarter of 2003 Sonex  took  delivery  of the  advanced
research  automotive  diesel engine to be used for the testing.  The engine is a
state-of-the-art,  three-cylinder,  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.

Early  stages of the Phase II project are  focusing on the  emissions  reduction
capabilities  of  the  SCS  pistons  separately,  while  subsequent  testing  in
combination   with  the  NEA  membrane  will   demonstrate   the  viability  for
commercialization  of the synergy of SCS  configurations  and the CMS membranes.
This  program  would  provide  SCS  in-cylinder  emissions  reduction  data on a
multi-cylinder  diesel  engine as a means for  diesel  engine  manufacturers  to
evaluate the potential for SCS designs,  alone and in  combination  with the NEA
membrane,  to reduce the cost and  complexity of future  exhaust  aftertreatment
systems.  While the entire  project is not expected to be completed  until 2004,
testing results on the SCS pistons alone may be available later this year.



                                   SAIC

In the third  quarter  of 2002 the  Company  received a  subcontract,  initially
funded for $200,000 and later increased to $281,947,  from Science  Applications
International Corporation (SAIC), a large DoD prime contractor. Sonex was tasked
to  conduct  a survey  of  commercially  available  two-stroke,  spark  ignited,
gasoline engines of approximately 72 horsepower and, jointly with SAIC, select a
candidate  engine for a "best  efforts" SCS  conversion  to start and operate on
heavy fuels for use in a UAV weapon system. SAIC also awarded a subcontract to a
competing firm to develop a heavy fuel conversion for a rotary engine already in
production.  SAIC and its military sponsor  subsequently  increased the targeted
horsepower  requirement  to 100.  Sonex and SAIC  together  selected a candidate
gasoline engine, not yet in production, for conversion to heavy fuel.

Due to  deficiencies  found in operating  the  candidate  engine on gasoline and
concurrent fuel consumption  problems experienced by the competing rotary engine
operating on heavy fuel, in the first quarter of 2003 the DoD sponsor  expressed
a desire to have Sonex work with the competing  rotary engine developer to focus
on improving the fuel  consumption  of the rotary HFE. This joint effort was not
formalized  because  work on the  engine  later was  placed on hold  while  SAIC
concentrated on resolving a number of technical  issues with the flight vehicle.
Subsequently,  the prime  contract to SAIC was  terminated by the DoD in October
2003.  Sonex now seeks to obtain  the  necessary  funding  from DoD to  continue
development  of this HFE,  and  others,  for use in  intermediate  size UAVs for
varied missions.


                             DOD PRIME CONTRACTOR

In September  2003 the Company  received a purchase order from another large DoD
prime  contractor to develop a combustion  system to convert two different small
gasoline  engines to start and operate on heavy fuels for potential use in UAVs.
The subcontract amount is $164,944,  and work is expected to be completed during
the first quarter of 2004.


Financial position and liquidity

The Company  operated under severe cash flow  difficulties  for extended periods
during 2001 and 2002. Its two officers  voluntarily  and at their own discretion
deferred  receipt of payment of  significant  portions of their current wages to
reduce the Company's  cash  requirements.  With the generation of cash flow from
revenues earned under contracts awarded to the Company during the second half of
2002, some of the amounts owed to the Company's officers were repaid in December
2002.  Also at that time the Company's  officers began  receiving  their current
wages.  During the first quarter of 2003 the Company's chief  executive  officer
once again began  deferring  some of his current wages and, since April 2003, he
has deferred all of his current  wages.  As of  September  30, 2003,  total such
wages payable to the Company's chief executive and chief financial officers were
$166,597 and $86,403, respectively.

The continued  deferral of portions of current  wages by the Company's  officers
cannot be expected to continue indefinitely, and the Company will be required to
pay amounts outstanding as soon as cash flow permits. Similarly, the Company has
accumulated unpaid consulting fees, the majority of which amounts are payable to
the individual who serves as the Company's director of business  development and
technical  program manager on a part-time  basis. As of September 30, 2003, this
individual  was owed  $41,175.  The  amount and  timing of  payments  for unpaid
compensation  owing  to the  Company's  officers  and  this  consultant  will be
determined at the discretion of the Company's officers; however, all such unpaid
compensation  is payable  upon demand,  as these  amounts are not subject to the
terms of the Company's  written  agreement with current and former  employees to
defer  payment of  portions  of their  salaries  as  described  in Note 6 to the
accompanying unaudited financial statements.

As of September 30, 2003,  the Company had available cash of $9,274 and accounts
receivable  of $159,434,  the entire  balance of which has been  collected as of
November  15,  2003.  The Company  historically  has derived the majority of its
revenues  from  engineering  and  development  funding  provided by  established
companies willing to assist the Company in the development of its SCS technology
and,  more  recently,  from  government  sources.  In  2002,  however,  revenues
increased  substantially,  providing  cash to fund the majority of the Company's
operating  expenditure  requirements for the year. All of the Company's  revenue
for 2002 and 2003 has been derived from development and demonstration  contracts
issued by a United States Government or DoD agency or prime contractor.  In 2003
revenues  from  development  and  demonstration  contracts  are again  expected,
although  there can be no  assurance,  to provide most of the cash  necessary to
fund operations.

Based upon  available  resources,  current and projected  spending  levels,  and
expected revenue from current and anticipated contracts, management believes the
Company will have sufficient  capital to fund operations through March 31, 2004.
The Company's prospects beyond that date are dependent upon its ability to enter
into  significant  funded  contracts  for  the  further  development  of its SCS
technology,  establish  joint  ventures  or  strategic  partnerships  with major
industrial concerns,  or secure a major capital infusion.  There is no assurance
that the Company will be able to achieve these objectives.

In the event  sufficient  funding is not  available  through the  generation  of
revenues  or from  external  sources,  the Company  would have to  substantially
reduce  the level of its  operations.  Such a  reduction  could  have an adverse
effect on the Company's relationships with government funding sources, strategic
partners and potential customers.

The accompanying unaudited financial statements have been prepared assuming that
the Company will continue as a going concern,  which contemplates  continuity of
operations,  realization  of  assets  and  satisfaction  of  liabilities  in the
ordinary course of business.  The propriety of use of the going concern basis is
dependent upon, among other things, the Company's ability to generate sufficient
revenue and ultimately achieve profitable operations.  These uncertainties raise
substantial  doubt about the Company's  ability to continue as a going  concern.
The accompanying financial statements do not include any adjustments relating to
the  recoverability  of the carrying amounts of recorded assets or the amount of
liabilities that might result from the outcome of these uncertainties.


Results of operations

A net loss of  $287,488  was  recorded  for the first  nine  months of 2003,  as
compared  to  $270,303  for the  corresponding  period in 2002,  a  increase  of
$17,185,  or 6%.  With the award of  several  significant  contracts  during the
second half of 2002, revenue nearly tripled in the current year versus the prior
year, with related  increases in expenses to support the new work resulting in a
slightly higher net loss in 2003.

[Note: In order to conform to the classifications  used in 2003, certain amounts
for 2002  presented in the prior  year's  financial  statements  as research and

development  expenses have been reclassified  below to cost of revenue.  The net
loss for each period does not change as a result of these reclassifications.]

Revenue increased  substantially from the first nine months of 2002 to the first
nine  months of 2003,  as during the second half of 2002 the Company was awarded
three  significant   contracts  and  subcontracts  from  branches  of  the  U.S.
government and DoD and/or their prime contractors. The following is a listing of
the three  major new  projects,  descriptions  of which  appear  earlier in this
report.


      Subcontract  awarded by  Science  Applications  International  Corporation
      (SAIC),  a large DoD prime  contractor.  Awarded  third  quarter  of 2002.
      Initial funding of $200,000, later increased by $81,947. Work suspended in
      first quarter of 2003;  the prime  contract to SAIC was  terminated by the
      DoD in October 2003.

      Prime contract  awarded by the Defense Advanced  Research  Projects Agency
      (DARPA).  Awarded  fourth  quarter of 2002.  Total  funding  of  $744,246.
      Completion expected in early 2004.

      Subcontract  awarded by Compact  Membrane  Systems,  Inc.  (CMS) under its
      prime  contract from the U.S.  Department of Energy (DOE).  Awarded fourth
      quarter of 2002.  Total award to Sonex of $458,862,  of which  $100,000 is
      cost-shared (funded) by Sonex. Completion expected sometime in 2004.


Cost of Revenue  primarily  consists of direct  labor  charges and other  direct
expenditures,  including those for consulting  services,  attributable to funded
programs,  as well as  allocated  fringe  benefits,  payroll  taxes,  and  labor
overhead  charges.  Cost of Revenue as a percentage of total  revenue  increased
from 49% in 2002 to 67% in 2003.






       Research and development (R&D) expenses:

   Other expenses                                        164,755         91,207

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


The following  analysis is based on a comparison of total R&D expenses as listed
above before deduction of amounts classified as cost of revenue.

Total R&D expenses for the first nine months of the year  increased by $310,246,
or 113%,  from  2002 to 2003.  The  largest  component,  employee  compensation,
increased by $158,802,  or 94%, as  additional  personnel  were hired during the
second  half of 2002  and the  first  half of 2003 to work on the new  contracts
received by the Company.  Another  factor was the recording of charges for stock
option  compensation in 2003 as the Company changed its method of accounting for
stock-based  compensation as described in Note 8 to the  accompanying  unaudited
financial  statements.  Such  charges,  totaling  $21,111  during the first nine
months of 2003 versus none in 2002,  represent the amortization over the related
vesting period of charges  associated  with option grants made in prior years as
well as in the current period.  Consulting fees also increased significantly due
to the engagement of a program manager and specialized  technical consultants on
the new contracts.  The increase in other expenses  primarily  relates to higher
purchases  of parts,  supplies  and  fabrication  services  to  support  the new
contracts.


       General and administrative (G&A) expenses:


                                                          Nine months ended
                                                            September 30,
                                                      -------------------------

                                                      ----------     ----------


   Employee compensation, taxes & benefits            $  118,614     $   82,226
   Consulting fees                                        99,860         43,896
   Professional fees                                      29,082         33,991
   Other expenses                                         51,418         42,405
                                                      ----------     ----------

   Total G&A expenses                                 $  298,974     $  202,518
                                                      ==========     ==========

Total G&A expenses  for the first nine months of the year  increased by $96,456,
or 48%,  from  2002 to  2003.  The  largest  component,  employee  compensation,
increased  by $36,388,  or 44%,  for a number of reasons.  Total  salaries  were
higher  as a result  of an  increase  in the  salary  (before  deferral)  of the
Company's chief financial officer effective January 1, 2003, and the hiring of a
part-time administrative assistant beginning in January 2003. Another factor was
the  recording of charges for stock option  compensation  in 2003 as the Company
changed its method of accounting as mentioned  previously.  Such charges totaled
$15,000 during the first nine months of 2003.

Consulting fees increased by $55,964,  or 127%, from 2002 to 2003 as the Company
has expanded its marketing and commercialization  capabilities in 2003 by hiring
specialized  consultants to provide business  advisory services in areas such as
strategic alliances,  federal marketing,  and government procurement assistance.
Such expenses in 2003 also include higher charges for stock option compensation,
including  charges  related to options  granted to directors in 2001, due to the
change in accounting  method  mentioned  above.  Professional  fees decreased by
$4,909,  or 14%, from 2002 to 2003,  reflecting the termination in early 2003 of
the Company's relationship with an investor relations firm engaged in the second
quarter of 2002. This decrease was nearly offset by higher auditing fees,  which
more  than  doubled  from  2002  to  2003  as the  Company  changed  independent
accountants for 2003 from a small local firm, which disbanded its public company
audit practice, to a larger regional firm.

Other expenses  increased by $9,013,  or 21%, from 2002 to 2003 primarily due to
higher office maintenance and equipment  depreciation  expenses  associated with
the increased level of business activity in 2003 over 2002.




ITEM 3.       CONTROLS AND PROCEDURES

The Company's chief executive officer and chief financial officer have evaluated
the effectiveness of the Company's  disclosure  controls and procedures (as such
term is defined in Rules 13a-14(c) and 15d-14(c)  under the Securities  Exchange
Act of 1934) as of an evaluation date within 90 days prior to the filing date of
this  Quarterly  Report  on Form  10-QSB.  Based on such  evaluation  they  have
concluded that, as of the evaluation date, the Company's disclosure controls and
procedures are effective to ensure that information  required to be disclosed in
reports that the Company  files or submits  under the Exchange Act, is recorded,
processed, summarized and reported in a timely manner.

Since the  evaluation  date  referred to above,  there have been no  significant
changes  in the  Company's  internal  controls  or in other  factors  that could
significantly affect such controls.
