                              SONEX RESEARCH, INC
                         NOTES TO 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 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-month  period  ended  March 31,  2004 are not
necessarily  indicative  of the results that may be expected for the year ending
December 31, 2004. 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, 2003.


NOTE 3 - REVENUE RECOGNITION AND MAJOR CUSTOMERS

All of the  Company's  revenue is derived  from  development  and  demonstration
contracts  issued by a United  States  Government  or Department of Defense (the
"Government") agency or prime contractor.  During the first quarter of 2004, the
Company had three such customers.

Revenue is recognized upon the Company's  completion of the milestones 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.


NOTE 4 - 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. In late April 2004 the Company
raised  cash  proceeds of $130,000 in  connection  with a private  financing  as
further described in Note 13.

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  until  approximately
September 30, 2004. The Company's  prospects beyond that time 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 5 - RESTRUCTURING COSTS

During  the  first  quarter  of  2004,  the  Company  experienced  a  number  of
significant  changes.  In February 2004 the Board of Directors was reconstituted
and a new  president  was hired to fill the position  that had been vacant.  The
Company's new president is developing and implementing an updated business plan,
the primary goal of which is to transition Sonex from a research and development
company into a technology and manufacturing  enterprise. In connection with this
change in business strategy, in February and March 2004 the Company entered into
an employment agreement with its new president and executed other agreements for
consulting services,  obtained a short-term loan from a shareholder,  authorized
additional compensation to its officers and directors, and satisfied liabilities
for accrued compensation, through the issuance of a substantial number of shares
of common stock. Details of these transactions are presented in Note 11.


NOTE 6 - DEFERRED CHARGES

Deferred charges of $72,000 at March 31, 2004 represent compensation recorded in
connection  with the issuance of common stock under the terms of the  employment
agreement  executed  with  the  Company's  new  president  in  February  2004 as
described  in detail in Note 11. The amount  recorded  as a current  asset as of
March 31, 2004 is for compensation  related to shares issued or to be issued but
not vested as of that date.  This  amount  will be  amortized  to expense on the
vesting dates of the remaining shares through February 2005.


NOTE 7 - DEBT

Short-term lines of credit

The Company has  obtained  business  credit  cards from  Capital One Bank with a
credit limit of $22,500 and Fleet  National Bank with a credit limit of $19,000.
Repayment of amounts due has been  personally  guaranteed by the Company's chief
executive  officer.  Balances in the Capital  One account  accrue  interest at a
fixed rate of 8.9% per annum, while the Fleet account has a promotional interest
rate of 0% through  June 2004,  adjusting to prime rate + 6%  thereafter.  As of
March 31, 2004, the  outstanding  balance on the account with Fleet was $14,500,
while the balance on the account with Capital One Bank was $8,532.


Capital Lease Obligations

During 2003 the Company incurred new capital lease  obligations in the principal
amount of $50,753 in connection with the acquisition of equipment. The repayment
of two, four-year equipment lease obligations in the principal amount of $46,598
included in this total has been  personally  guaranteed by the  Company's  chief
executive  officer.  As of March 31, 2004, the aggregate  outstanding  principal
balance on these two lease obligations was $34,511.


Notes Payable to Shareholder

In June 2003 the Company  issued a $50,000,  6% note to one of its  shareholders
payable  initially  on  December  31,  2003.  The due date of this note has been
extended to June 30, 2004. In March 2004 the Company  issued a $50,000,  6% note
to this same  shareholder,  payable on June 30,  2004.  Payment of both notes is
secured by Company revenues.

In  connection  with a private  financing  in March 2002,  the Company  issued a
$6,000, 6% note to this shareholder, 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 June 30, 2004.


NOTE 8 - ACCRUED COMPENSATION AND BENEFITS

Accrued  compensation  consists of the following  amounts payable to current and
former employees:


                                                 March 31,        December 31,
                                                    2004              2003
                                                -----------       -----------

     Accrued wages and payroll taxes            $   301,347       $   299,635
     Accrued consulting fees                        195,739           150,181
     Accrued bonuses                                152,961           154,068
     Accrued vacation pay                            56,724            53,610
                                                -----------       -----------

                                                $   706,771       $   657,494
                                                ===========       ===========

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,  from April 2003  through  December  2003,  he deferred  all of his current
wages.  As of March 31, 2004,  total such wages payable to the  Company's  chief
executive and chief financial officers were $190,157 and $86,403, respectively.

The deferral of payment of such wages owed to 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 significant unpaid consulting fees, the majority of which amounts as
of March  31,  2004 (a total of  $139,180)  are  payable  to three  individuals,
including  the  Company's  chief  executive  officer who, as of January 2004, is
being compensated as a consultant rather than as an employee.  In March 2004 the
Company  paid $24,000 of such  previously  accrued  consulting  fees through the
issuance of common stock.

The amount and timing of payments for unpaid compensation owing to the Company's
officers  and  its  consultants  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 9.

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 March 2004 the Company paid $24,000 of
such previously accrued bonuses through the issuance of common stock. The amount
of accrued  bonuses  included  in the table above that was payable to two of the
Company's officers at March 31, 2004 is $98,500. Payment of such accrued bonuses
is 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 9.

In February  2004 in connection  with the execution of an employment  agreement,
the Company  awarded a bonus of $33,000 to its new  president,  with  payment of
$25,000 of this amount being deferred until February 2006 under the terms of the
employment  agreement.  The deferred portion is included with accrued bonuses in
the table above.

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 March 31, 2004 was $49,998.  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 9.


NOTE 9 - 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  for  several  years  voluntarily   deferred  receipt  of  payment  of
significant  portions of their authorized  annual salaries 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 11.
The individuals who are parties to this agreement have consented to 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.

Under the terms of an  employment  agreement  executed  in  February  2004,  the
Company's new  president is deferring  annually  $68,000 of his $140,000  salary
until March 2006 or until such earlier date as the Board of Directors determines
that the Company's cash flow is sufficient to allow payment.

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


                                                 March 31,        December 31,
                                                    2004              2003
                                                -----------       -----------


     Current officers                           $   644,365       $   641,749
     Current employees                               12,504            12,504
     Former officers, employees and consultants     311,197           311,197
                                                -----------       -----------

                                                $   968,066       $   965,450
                                                ===========       ===========

The amount reported above for deferred  compensation payable to current officers
as of March 31,  2004  consists  of  $486,424  payable  to the  Company's  chief
executive  officer and $155,326  payable to its chief financial  officer.  As of
January 1, 2004, the Company's chief executive officer is being compensated as a
consultant  rather  than a salaried  employee,  with  related  compensation  not
subject to the terms of the written  agreement  described above for the deferral
of payment of current  compensation.  Also as of January 1, 2004,  the Company's
chief  financial  officer is no longer  deferring  any  portion  of his  current
salary.

The conditions that would require repayment of such deferred amounts have yet to
occur,  and it is unlikely  that such  conditions  will occur prior to March 31,
2005.  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.

The amount  reported  for current  officers  as of March 31, 2004 also  includes
$2,615 owed to the Company's  new president in accordance  with the terms of his
employment  agreement  executed in February 2004. The agreement requires the new
president to defer annually  $68,000 of his $140,000 salary until the expiration
of the agreement in March 2006 or at such earlier date as the Board of Directors
determines that the Company's cash flow is sufficient to allow payment.


NOTE 10 - INCOME TAXES

The  Company  has not  incurred  any  federal or state  income  taxes  since its
inception  due to operating  losses.  At December 31, 2003,  the Company had net
operating loss carryforwards of approximately  $11.2 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  $7.9 million have expired unused. Net operating loss
carryforwards of  approximately  $1.2 million are scheduled to expire at the end
of 2004.


NOTE 11 - 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 for $2 million in February 1992 (the "Preferred
Stock Investment") to 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 March 31, 2004 a total of
459,999 shares of preferred  stock had been  converted into 1,314,278  shares of
common stock.


Stock options and other equity-based compensation

The Company  maintains a  non-qualified  stock  option plan created in 1987 (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 February 2014.

From  January 1, 2004  through  March 31,  2004,  the Company had the  following
activity in options to purchase shares of common stock under the Plan:


                                            Weighted                Weighted

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

The Company accounts for stock options and other stock-based  compensation under
the fair value based method in accordance with Statement of Financial Accounting
Standards  (SFAS) No.  123 -  "Accounting  for  Stock-based  Compensation".  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 which takes into account weighted
average assumptions for stock price volatility,  average risk-free interest rate
of return,  expected  dividend yield,  and average  expected term. For the three
months ended March 31, 2004 and 2003, in connection  with options  granted under
the Plan,  the Company  recorded  stock option  compensation  under SFAS No. 123
totaling $11,161 and $25,666,  respectively.  The amount of compensation expense
is also credited to additional paid-in capital.

Under the terms of an  employment  agreement  executed  in  February  2004,  the
Company's new president  was granted a ten-year  option,  not under the Plan, to
purchase  500,000 shares of common stock,  which will vest and be exercisable in
accordance with the schedule presented below.  During the first quarter of 2004,

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
the fair value of options granted by the Company.

Also under the terms of the February 2004 employment  agreement mentioned above,
the  Company  will issue to its new  president  a total of  1,000,000  shares of
common  stock  for cash of $.01 per  share.  Of this  total,  the new  president
currently  purchased  800,000  shares,  with 200,000 of these shares having been
transferred to the new president upon execution of agreement,  and the remaining
shares  being held in escrow  pending  vesting  of  200,000  shares at a time in
three,  six and  nine  months.  The  Company  is  obligated  to issue to its new
president an additional  200,000  shares of common stock for cash of $.01 per in
February  2005.  With  respect to this total of 1 million  shares,  the $.09 per
share  discount  between the purchase price and the market price of the stock of
$.10 per share on the effective  date of the  employment  agreement is accounted
for as  compensation  for a total amount of $90,000.  As of March 31, 2004,  the
Company has  charged to expense  compensation  of $18,000  for the shares  which
vested  immediately,  and has recorded  $72,000 in deferred charges as a current
asset and will  amortize  such  charges to expense on the  vesting  dates of the
remaining shares.

Also in connection with the consulting  agreement  mentioned  above, in February
2004 the Company  issued  1,530,000  shares of common stock and has reserved for
issuance during the second quarter of 2004 an additional  420,000  shares.  With
respect to this total of 1,950,000 shares,  during the first quarter of 2004 the
Company has  charged to expense  compensation  of  $195,000  based on the market
price of the stock of $.10 per  share on the  effective  date of the  consulting
agreement,  of which total $42,000 has been recorded as accrued  consulting fees
as of March 31, 2004  relating to the shares  remaining  to be issued  under the
consulting agreement.

Also  during  the  first  quarter  of  2004,  the  Company  recorded  additional
compensation through the issuance of shares of common stock as set forth below.

NOTE 12 - COMMITMENTS

In February 2004 the Company  entered into an employment  agreement with its new
president  which  expires in March 2006.  The  agreement  provides for an annual
salary  of  $140,000,  of which  $68,000  must be  deferred  annually  until the
expiration  of the  agreement  or at such earlier date as the Board of Directors
determines that the Company's cash flow is sufficient to allow payment.

Pursuant to the terms of the March 2004 agreement  with new legal  counsel,  the
Company is obligated to remit a cash retainer of $50,000 by June 30, 2004.

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.


NOTE 13 - SUBSEQUENT EVENT

In a private  financing  transaction  in late April  2004,  the  Company  raised
$130,000  through the issuance of 520,000  shares of the Company's  common stock
and warrants to purchase an  additional  520,000  shares of common stock at $.35
per share  through  May 6,  2006.  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.

Company Overview

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

  |X| reduce emissions of diesel engines
  |X| increase fuel mileage of a new  generation of gasoline  engines
  |X| 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 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  by using  direct
injection  and  patented  Sonex  designs.  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 HFEs to military and commercial markets.

As of March  31,  2004,  the  Company  has  seven  full-time  employees  and two
part-time  employees,  and engages the  part-time  services of a consultant  who
serves as its  director  of  business  development  and  manager  of  government
programs.  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

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.

In 2003 the Company  began  taking  steps to focus on  business  re-positioning,
strengthening its internal  capabilities,  and planning for growth.  The Company
engaged  consultants to assess the SCS technologies and business model,  suggest
approaches for strategic  alliances,  and provide federal marketing,  government
procurement assistance, and commercialization services.  Management identified a
need   to   secure   strong   strategic   alliances   for  the   marketing   and
commercialization  of the  SCS  engine  applications  by  leveraging  technology
development  currently  supported by U.S.  Government funding as well as seeking
relationships  with companies which have technologies  complementary to the SCS.
One of the  first  objectives  on this  path  was to  strengthen  the  Company's
management team.

During  the  first  quarter  of  2004,  the  Company  experienced  a  number  of
significant  changes.  In February 2004 the Board of Directors was reconstituted
and a new  president  was hired to fill the position  that had been vacant.  The
Company's new president is developing and implementing an updated business plan,
the primary goal of which is to transition Sonex from a research and development
company into a technology and manufacturing  enterprise.  There is no assurance,
however,  that the Company  will be able to complete  and  implement  an updated
business plan.


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 SCS 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 over $23 million,  and anticipates  incurring 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 have provided  most of the  necessary  operating  cash for the last two
years.

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  with the exception of the new
president hired in February 2004.

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 March 31, 2004,  there were  25,782,669  shares of
Common  Stock  issued and  outstanding,  with an  additional  13,386,832  shares
reserved for future  issuance,  primarily upon the conversion of preferred stock
and the exercise of options and warrants.


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.


Financial position and liquidity

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, from April 2003 through  December  2003, he has deferred all of his current
wages.  As of March 31, 2004,  total such wages payable to the  Company's  chief
executive and chief financial officers were $190,157 and $86,403,  respectively.
Similarly,  the Company has accumulated  significant unpaid consulting fees, the
majority of which amounts as of March 31, 2004 (a total of $139,180) are payable
to three individuals, including the Company's chief executive officer who, as of
January 2004, is being compensated as a consultant rather than as an employee.

The deferral of payment of current  compensation owed to the Company's  officers
and  consultants  cannot be expected to continue  indefinitely,  and the Company
will be required to pay amounts  outstanding  as soon as cash flow permits.  The
amount and timing of payments  for unpaid  compensation  owing to the  Company's
officers  and  its  consultants  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  9 to  the  accompanying  financial
statements.

As of March  31,  2004,  the  Company  had  available  cash and  equivalents  of
approximately $22,195 and accounts receivable, including contract costs incurred
but not yet billed, of $60,589.  All such receivables have been collected by the
Company  as of the date of this  report.  In  addition,  in late  April 2004 the
Company raised cash proceeds of $130,000 in connection with a private  financing
as further described in Note 13 to the accompanying financial statements.

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.   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 until  approximately  September 30, 2004.
The Company's prospects beyond that time 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.

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 a material
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 $686,867 was recorded for the first  quarter of 2004,  as compared
to $101,738  for the  corresponding  period in 2003,  an  increase of  $585,129.
Slightly lower revenue and  substantially  higher total expenses,  a significant
portion of which expenses relate to the restructuring undertaken by the Company,
accounted for the much larger net loss in the current period.

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


Revenue  decreased  by $39,589,  or 23%,  from the first  quarter of 2003 to the
first  quarter of 2004,  as work wound down in 2004 on two major  projects  from
branches of the U.S.  government  and DoD and/or their prime  contractors  which
were  awarded to the Company  during the second half of 2002.  Combined  revenue
from these two projects  decreased from $118,624 in the first quarter of 2003 to
$91,947 in the current  period.  Management  believes  the  prospects  are good,
although  there can be no  assurance,  that in the near future it will receive a
follow-on  award to the larger of these two contracts from the Defense  Advanced
Research Projects Agency (DARPA) for heavy fuel engine  technology  development.
With respect to the second,  a  subcontract  for the Company's  diesel  emission
reduction  technology from Compact Membrane Systems,  Inc. (CMS) under its prime
contract from the U.S.  Department of Energy (DOE),  the Company has received an
indication  from the DOE that  funding  to Sonex  for this  project  will not be
continued.

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 quarter of 2003 was 62%
of revenue, in the first quarter of 2004 cost of revenue substantially  exceeded
revenue, primarily due to significant, unanticipated project cost overruns.

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

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 three months of the year  increased by $13,231,
or 7%, from 2003 to 2004, as a reduction in overall  employee  compensation  was
more  than  offset  by  higher  consulting  fees and  other  expenses.  Employee
compensation  decreased by $29,201,  or 28%, as slight increases  resulting from
higher  salary  rates in 2004  were more than  offset by  significant  decreases
relating to the  termination in the second half of 2003 of the employment of one
engineer  and the change in status as of  January  2004 of the  Company's  chief
scientist and CEO from salaried  employee to  consultant.  This change in status
accounted for the increase in consulting  fees of $16,589,  or 54%, from 2003 to
2004.

The increase in other  expenses of $25,843,  or 52%,  from 2003 to 2004 reflects
charges  incurred  in the  first  quarter  of 2004  for  outside  machining  and
fabrication  services  for  components  for  ongoing  funded  projects  and  the
write-off of unamortized patent costs on certain older foreign patents abandoned
by the Company.

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


Total G&A  expenses  for the first  three  months of the year  increased  nearly
seven-fold  from  the  comparable  period  in the  prior  year,  largely  due to
substantial  charges  incurred  with  the  hiring  of a  new  president  who  is
developing and  implementing an updated business plan, the primary goal of which
is to transition Sonex from a research and development company into a technology
and manufacturing enterprise.

Employee compensation increased by $81,277 from 2003 to 2004, as charges for the
compensation of the new president totaled $83,218.  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.  The  Company's  new
president is deferring  payment of nearly 50% of his annual  salary.  Charges in
2004 also  include  bonus  compensation  valued at $10,000  paid in stock to the
Company's chief financial officer. These increases were slightly offset by lower
expenses for clerical help and lower stock option compensation charges for other
employees in 2004 versus 2003.

Consulting fees in 2004 include charges  aggregating  $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.

The  increase  in  professional  fees of  $123,272  from  2003 to 2004 is almost
entirely  due to a charge  in the  first  quarter  of 2004 for a  non-refundable
retainer to the Company's new securities  legal counsel  payable in stock valued
at $120,000.

The increase in other  expenses of $30,990  from 2003 to 2004 is related  almost
entirely to  stock-based  compensation  in the first quarter of 2004 for outside
directors.




ITEM 3.       CONTROLS AND PROCEDURES

Disclosure 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 the end of the period  covered by this report.  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.


Internal Control over Financial Reporting

It is the  responsibility of the Company's  management to establish and maintain
adequate  internal control over financial  reporting.  Due to its small size and
limited financial  resources,  however, the Company's chief financial officer, a
member of  management,  has been the only employee  involved in  accounting  and
financial  reporting.  The Board of Directors has  recognized  that as a result,
there is no segregation of duties within the  accounting  function,  leaving all
aspects of financial  reporting and physical  control of cash and equivalents in
the hands of the same  employee.  Usually,  this lack of  segregation  of duties
represents a material  weakness in a company's  internal  control over financial
reporting;  however,  based on the demonstrated integrity and trustworthiness of
the  Company's  chief  financial  officer  and  the  oversight  provided  by the
Company's  independent  accountants,  the Board of Directors has had  confidence
that there have been no irregularities in the Company's  financial  reporting or
in the  protection  of its  assets  as a result  of this  potentially  potential
material  weakness in the Company's  internal control over financial  reporting,
and that, under the circumstances, internal control over financial reporting has
been as effective as is possible.

As of April 2004,  the Board of Directors has  implemented  additional  internal
controls by assigning certain responsibilities for the handling of incoming cash
to the new  president  of the Company.  There have been no other  changes in the
Company's  internal  control over financial  reporting since March 31, 2004 that
have materially  affected,  or are reasonably likely to materially  affect,  the
Company's  internal control over financial  reporting.  As soon as is practical,
the Board of Directors  will  consider  the  assignment  of specific  duties for
various other aspects of internal control over financial  reporting to its chief
executive officer and its president.

ITEM 2.  CHANGES IN SECURITIES

In the first  quarter of 2004,  the Company  issued an  aggregate  of  4,190,000
shares of common  stock and options and  warrants  to purchase an  aggregate  of
1,250,000 shares of common stock,  without registration under the Securities Act
of 1933 (the "Securities Act"), as follows:


      In February 2004 under the terms of an employment  agreement,  the Company
      issued to its new  president  800,000  shares of common  stock for cash of
      $.01 per share. Of this total, 200,000 shares have been transferred to the
      new president upon execution of the  agreement,  and the remaining  shares
      are being held in escrow  pending  vesting of 200,000  shares at a time in
      three, six and nine months.  The Company is also obligated to issue to its
      new  president an  additional  200,000  shares of common stock for cash of
      $.01 per in February  2005.  In addition,  the Company's new president was
      granted a ten-year  option,  not under the  Company's  1987  Non-Qualified
      Stock  Option  Plan (as  amended),  to purchase  500,000  shares of common
      stock, which will vest and be exercisable in accordance with the following

      In February  2004 under the terms of a consulting  agreement,  the Company
      issued  1,530,000  shares of common  stock and has  reserved  for issuance
      during  the  second  quarter  of 2004 an  additional  420,000  shares  for
      services valued at $.10 per share. Also in connection with this agreement,
      the Company issued ten-year,  immediately exercisable warrants to purchase
      750,000 shares of common stock at the following prices:  250,000 shares at
      $.35, 250,000 shares at $.55, and 250,000 shares at $.75.

      In February  2004 the Company  issued an  aggregate  of 250,000  shares of
      common stock to its officers and employees as bonus compensation valued at
      $.10 per share.

      In March 2004 the Company  issued  10,000 shares of common stock valued at
      $.12 per share in  connection  with the  issuance  of a note  payable to a
      shareholder.

      In March 2004 upon execution of an agreement  with new legal counsel,  the
      Company  issued  1,000,000  shares of common stock for services  valued at
      $.12 per share.

      In March 2004 the Company satisfied  liabilities for accrued  compensation
      and consulting fees through the issuance of an aggregate of 400,000 shares
      of common stock valued at $.12 per share.

      In March 2004 the Company  issued 200,000 shares of common stock to one of
      its independent directors for services valued at $.12 per share.


The Company views these issuances as transactions by an issuer not involving any
public  offering and therefore as exempt from  registration  under Sections 4(2)
and/or 4(6) of the Securities Act. The certificates representing such shares are
endorsed  with a standard  restrictive  legend  stating that the shares have not
been registered under the Securities Act or in any state or other  jurisdiction,
and  that no  disposition  of the  shares  may be  made  unless  pursuant  to an
effective  registration  statement  or upon the  issuance  of an  opinion of the
Company's  legal  counsel that the  disposition  may be made pursuant to a valid
exemption from any registration requirements.
