                                  THE COMPANY
 
    RODI Power Systems, Inc. ("RODI" or the "Company") is a development stage
company which is engaged in the design and development of the Company's initial
product, the HT1-450 diesel engine. The HT1-450, which has been under
development since 1993, is a V-4 cylinder rod-crank turbo diesel engine designed
to generate 300 to 500 horsepower for use in Class 8 heavy duty trucks, boats
and stationary power applications. If development of the HT1-450 is successfully
completed, the Company intends to manufacture, market and sell the HT1-450
engine and to develop, commercialize, and sell other high horsepower engines
utilizing this engine design for trucks, boats and stationary power
applications. The Company has also recently commenced distribution of a third
party's engines to a newly formed joint venture, Alternate Power Equipment, Inc.
 
    RODI believes its initial entry into the heavy diesel truck market will be
enhanced by the unique product features inherent in the HT1-450 engine:
 
    - With its unique reverse uniflow two-stroke cycle, V-4 configuration, and
      two point microprocessor engine control, the HT1-450 is designed to be
      significantly lighter in weight and smaller in size than competitive
      engines without using any exotic materials, resulting in an increase in
      payload for any truck using it.
 
    - The HT1-450 design has the unique capability of permitting the power head
      to be separated from the accessory drive unit and removed from the vehicle
      without breaking any connections to the power steering pump, air
      conditioning compressor, alternator or air brake compressor. This will
      allow the engine to be removed from the truck and replaced with another
      engine, thus minimizing repair time and without any loss of hydraulic
      fluid or refrigerant.
 
    - The HT1-450 is designed to operate on two of its four cylinders when
      lightly loaded or when idling to improve operating efficiencies.
 
    - The HT1-450, with its reverse uniflow two-stroke cycle design, is
      constructed with approximately 40% fewer parts than its competitors'
      engines. This design is expected to reduce costs associated with
      manufacturing and servicing the engine.
 
    - The HT1-450 is designed to be used with synthetic oil (polyalphaolefin)
      for both lubrication and cooling. Using synthetic oil as a coolant
      eliminates the risk of freeze damage to the cylinder block and head and
      permits the engine to safely operate at up to 240 degrees Fahrenheit.
 
    - The two point microcompressor engine control will permit both the
      initiation and termination of fuel injection to be independently adjusted
      on each cylinder. This is expected to result in quick starts, smooth
      operation and minimal exhaust emissions.
 
    The Company is also developing the natural gas fueled HT2-300G, which is
designed to use the conventional four-stroke engine cycle with spark ignition
while retaining most of the other innovations under development on the HT1-450.
The HT2-300G uses approximately 80% of the HT1-450's engine components, and is
designed to be a low cost product specifically intended for electrical power
generation
 
                                       3
<PAGE>
and water pumping. The HT2-300G four-stroke engine is based on fully proven
design principles currently in the marketplace. The Company believes that the
primary competitive advantage of this engine will be its simplicity, low cost
and rugged packaging approach for application in the stationary power market.
 
THE DEVELOPMENT PROGRAM
 
    CURRENT STATUS OF HT1-450 ENGINE.  RODI has fabricated and tested three
prototype HT1-450 diesel engines. These engines have satisfactorily completed
the following design and performance parameters: validation of the reverse
uniflow cycle, dynamic balancing, structural adequacy, and piston and piston
ring configuration. These three engines have accumulated many hours of test
operation on the Company's dynamometer test stand and limited road testing in
the Company's class 8 heavy truck.
 
    Further development of the HT1-450 will be required before this product can
be commercialized. Tests are planned to enhance performance and increase maximum
power output of the HT1-450 by greatly increasing air flow through the engine by
optimizing air cycle components such as intake valves, exhaust port geometry,
supercharger volume ratio and turbocharger matching. Variables to be tested
include various exhaust system geometry changes; the use of four intake valves
per cylinder and using several types and combinations of supercharger and
turbocharger. Optimizing the air cycle of a two-stroke engine is a complex
trade-off of many characteristics that are interrelated. Recently completed
cylinder liner and piston design changes are expected to resolve past problems
associated with oil cooling and will be verified by testing during the first
phase of the pre-production engine development program. However, until these
design changes are tested, there are no assurances that they will be successful.
A technical status report on the HT1-450 program by David T. Marks, an
independent engine expert, is contained in Appendix A to the Prospectus. For
further information regarding development of the HT1-450 engine, see
"Business--The Development Program."
 
    HT1-450 DEVELOPMENT PROGRAM PLAN.  If the Maximum Amount is raised, RODI
intends to fabricate 25 pre-production HT1-450 engines for use in completing the
development program. These engines will be divided into four groups; five
engines for component integration verification testing, five engines for
dynamometer endurance testing, five engines for manufacturing engineering
development and ten engines for in-truck highway testing. RODI will also
fabricate several two-cylinder test modules to facilitate development testing.
If the Minimum Amount is raised, RODI intends to fabricate 10 HT1-450 pre-
production engines, with two engines each for component integration, dynamometer
endurance and manufacturing engineering, and four engines for in-truck highway
testing.
 
    HT2-300G DEVELOPMENT PROGRAM.  RODI intends to fabricate 10 HT2-300G engines
for the development program. The engines will be divided into two groups; four
will be used in-house for dynamometer and direct generator drive testing and six
will be provided to Alternate Power Equipment, Inc. for a cooperative test
program.
 
RECENT JOINT VENTURE
 
    The Company has a one-third interest in a recently formed joint venture,
known as Alternate Power Equipment, Inc., ("APE"). The joint venture was formed
to manufacture and sell stationary power systems under the Alternate Power
Equipment brand name. The Company is the exclusive supplier of engines to APE
and has been granted Original Equipment Manufacturer status with Deere Power
Systems to provide the Company access to John Deere's complete 80 to 500
horsepower line of PowerTech diesel engines. APE recently commenced production
of its initial diesel-electric stationary power system utilizing the PowerTech
engine. RODI manufactured engines will be integrated into the product line as
they become available. See "Business--APE Joint Venture". For further
information regarding development of the HT2-300G engine, see "Business--The
Development Program."

HISTORY OF THE COMPANY
 
    The Company was founded by Byron R. Spain in 1985 as a sole proprietorship,
incorporated as a Delaware corporation in 1987 under the name Rotary Diesels,
Inc. (RODI) and reincorporated in Washington in 1991. Until 1993, the Company
was engaged in the development of a rotary diesel engine. In 1993 the Company
elected to discontinue its development of a rotary diesel engine, due to the
projected cost and timing to develop a marketable product and management's
belief that the trucking industry had a general distrust of rotary engines, and
commenced development of the current reverse uniflow design. In 1993 the Company
was renamed RODI Power Systems, Inc. to more accurately reflect RODI's business
goals. The Company's principal executive offices are located at 7503 South 228th
Street, Kent, Washington 98032, telephone (253) 850-1490, and its mailing
address is P.O. Box 769, Maple Valley, WA 98038.

                                  RISK FACTORS
 
    THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE DISCUSSED IN
THE FORWARD-LOOKING STATEMENTS AS A RESULT OF CERTAIN FACTORS, INCLUDING THOSE
SET FORTH BELOW AND ELSEWHERE IN THIS PROSPECTUS. AN INVESTMENT IN THE UNITS
OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK AND IS NOT AN APPROPRIATE
INVESTMENT FOR PERSONS WHO CANNOT AFFORD THE LOSS OF THEIR ENTIRE INVESTMENT.
PROSPECTIVE INVESTORS SHOULD BE AWARE OF THE FOLLOWING RISK FACTORS AND SHOULD
REVIEW CAREFULLY THE FINANCIAL AND OTHER INFORMATION PROVIDED BY THE COMPANY.
 
DEVELOPMENT STAGE ENTERPRISE; LIMITED OPERATING HISTORY;
  ABSENCE OF REVENUES AND PROFITS
 
    The Company is a development stage enterprise and is subject to all of the
attendant business risks associated with a development stage enterprise,
including constraints on financial and personnel resources, lack of established
credit facilities, and uncertainties regarding product development and future
revenues. The Company will continue to be subject to all the risks attendant to
a development stage enterprise for the foreseeable future, including
competition, complications and setbacks in the development program, and the need
for additional capital.
 
    The Company has reported losses in each year since its inception. At April
30, 1997, the Company had an accumulated deficit of ($3,677,746). The Company's
history consists almost entirely of development of its products funded entirely
from the sale of its Common Stock in the absence of revenues. The Company
anticipates that it will continue to incur substantial additional operating
losses for at least the next 12 months and expects cumulative losses to increase
as the Company's development efforts expand. Since 1993 the Company has focused
on developing and testing the HT1-450 reverse uniflow two-stroke cycle turbo
diesel engine which the Company believes has long term potential.
 
    Although the Company anticipates receiving future revenues from the sales of
engines to a recently formed joint venture, Alternate Power Equipment, Inc.,
which engines are built by a third party and will not utilize the Company's
engine design until the current development program is completed, to date, the
Company has received minimal revenues from this activity, and there are no
assurances that significant revenues will be derived from this activity in the
future. The Company has received no revenues from sales of any of the products
under development. There can be no assurance as to when or if the Company will
be able to develop significant sources of revenue or whether its operations will
become profitable, even if it is able to commercialize any product. See
"Management's Discussion and Analysis of Financial Condition and Plan of
Operation," "Business--APE Joint Venture" and Notes to Financial Statements.
 
NO ASSURANCE OF SUCCESSFUL PRODUCT DEVELOPMENT OR COMMERCIALIZATION
 
    Although substantial progress has been made by the Company in developing the
HT1-450 and HT2-300G engines, substantial additional development will be
necessary in order for the Company to fully develop these products. There can be
no assurance that the engines will be developed or that they will be
commercialized by the Company in a timely manner or at all. Although development
efforts to date have validated the feasibility of the reverse uniflow design,
there are significant developmental milestones which the Company has not yet
achieved, such as sustained power operation in a Class 8 truck. Although the
Company believes that these milestones can be met, or alternative designs or
techniques employed if necessary, there are no assurances that these milestones
can be met or that these alternatives can be successfully implemented. This will
require further development related to the engine's extensive laboratory and
field testing, regulatory approval, and substantial additional investment by the
Company. This process could take two years or longer. There can be no assurance
that the products utilizing the reverse uniflow design will ultimately be
successfully developed, prove to be reliable in laboratory and field testings,
meet applicable regulatory standards, be capable of being produced in commercial
quantities at acceptable costs, be successfully marketed or achieve market
acceptance. Accordingly, any product
 
                                       8
<PAGE>
development program undertaken by the Company may be curtailed, redirected or
eliminated at any time, which could have a material adverse effect on the
Company. See "Business-The Development Program"
 
NEED FOR ADDITIONAL FINANCING
 
    The Company anticipates that, if the Maximum Amount is raised, the net
proceeds from this Offering will enable it to meet its capital and operational
requirements for at least 16 months following completion of the Offering.
Thereafter, additional funds will be required unless the Company is able to
generate revenues internally. Although the Company believes that it may be able
to generate such funds internally from revenues derived from the joint venture
with APE, there are no assurances that such funds will be available, or in
amounts required to fund ongoing capital needs. If the Company generates the
Minimum Amount, the Company believes that it will have sufficient funds to
complete development of the HT1-450 engine, but at a much slower pace
(approximately 30 months) due to continued use of part time personnel and
without the benefit of additional facilities and equipment.
 
    The Company's expectations as to the amount of funds needed for development
and the timing of the need for these funds is based on the Company's current
operating plan, which can change as a result of many factors, and the Company
could require additional funding sooner than anticipated. The Company's cash
needs may vary materially from those now planned because of results of
development or changes in the focus and direction of the Company's development
program, competitive and technological advances, results of laboratory and field
testing, requirements of regulatory agencies and other factors.
 
    The Company has no credit facility or other committed sources of capital. To
the extent capital resources are insufficient to meet future capital
requirements, the Company will have to raise additional funds to continue
development and operations of the Company. There can be no assurance that such
funds will be available on favorable terms, or at all. To the extent that
additional capital is raised through the sale of equity or convertible debt
securities, the issuance of such securities could result in dilution to the
Company's shareholders. If adequate funds are not available, the Company may be
required to curtail operations significantly or to obtain funds on unattractive
terms. The Company's inability to raise capital would have a material adverse
effect on the Company. See "Use of Proceeds" and "Management's Discussion and
Analysis of Financial Condition and Plan of Operation."
 
GOING CONCERN DISCLOSURE IN INDEPENDENT AUDITOR'S REPORT
 
    The report of the Company's independent auditors with respect to the
Company's financial statements included in this Prospectus includes a "going
concern" qualification, indicating that the Company's losses and deficits in
working capital and shareholders' equity raise substantial doubt about the
Company's ability to continue as a going concern. See "Management's Discussion
and Analysis of Financial Condition and Plan of Operation" and Notes to
Financial Statements.
 
LACK OF EXPERIENCE TO MANUFACTURE OR MARKET PRODUCT
 
    Assuming RODI is successful in developing HT1-450 and HT2-300G engines, the
Company presently has no proven ability either to manufacture or market the
engine. There is no assurance that the Company will be able to profitably
manufacture and market engines.
 
COMPETITION
 
    The diesel and natural gas engine market is extremely competitive. The
Company expects competition in the diesel and natural gas engine market to
continue, if not intensify, as the demand for more efficient and reliable
engines increases and new technologies and systems are developed to deliver such
engines in a cost-effective and convenient manner. The primary suppliers of
heavy duty diesel engines (Caterpillar, Detroit Diesel and Cummins Engine) and
natural gas engines (Caterpillar, Cummins and Waukesha Dresser) are major
national businesses with long established operating histories and significant
market
 
                                       9
<PAGE>
shares. These companies possess greater technical resources and market
recognition than RODI, and have management, financial and other resources not
yet available to the Company. Existing engines are likely to be perceived by
many customers as superior or more reliable than any new product until it has
been in the marketplace for a period of time. There is no assurance that the
Company will be able to compete effectively with these companies.
 
FLUCTUATIONS IN OPERATING RESULTS
 
    The Company's quarterly operating results will depend upon the timing of new
product introductions by the Company. The Company's quarterly operating results
may also fluctuate significantly depending on other factors, including the
introduction of new products by the Company's competitors, regulatory actions,
market acceptance of the Company's products, adoption of new technologies, and
manufacturing costs and capabilities. See "Management's Discussion and Analysis
of Financial Condition and Plan of Operation."
 
TECHNOLOGICAL CHANGE
 
    The HT1-450 engine, if successfully developed, is designed to have features
superior to truck engines presently on the market, particularly in the
power-to-weight-ratio. However, new technology or refinement of existing
technology could render the HT1-450 less attractive or obsolete. The Company's
success depends in part upon its ability to anticipate changes in technology and
industry standards and to successfully develop and introduce new and improved
engines on a timely basis. There is no assurance that the Company will be able
to do so.
 
DEPENDENCE ON KEY PERSONNEL
 
    The success of the Company depends on the abilities and continued
participation of Byron Spain, Donavan Garman and other key personnel who have
been instrumental in bringing the HT1-450 engine to its present state of
development. The loss of any of these key individuals could hamper the
successful development of the engine. The Company does not have "key man" life
insurance on such officers and currently has no plans to obtain such insurance.
See "Management". The Company's success also depends on its ability to attract
and retain additional skilled employees.
 
GOVERNMENT REGULATION
 
    Engines are subject to government regulation in the areas of emissions and
product safety. Truck companies and carriers are informally monitored by a
variety of state and local regulatory agencies. The HT1-450 and HT2-300G must
comply with state and federal anti-pollution and safety laws. There is no
assurance that the engines being developed will be capable of complying with all
such laws and regulations. See "Business--Government Regulation."
 
PRODUCT LIABILITY
 
    The HT1-450 engine is designed to power truck combinations weighing up to
120,000 pounds. As a key element of engine development, the Company is
addressing product safety and will document failure mode and effects analysis.
Despite the steps being taken, there is no assurance the HT1-450 will meet
adequate safety standards. This is often not known until after extensive field
trials are completed. The Company intends to purchase product liability
insurance during the highway test phase of development as well as during
production. The Company may become subject to strict liability for damages or
injuries caused by its products. Although the Company plans to carry product
liability insurance, there can be no assurance that adequate insurance will be
available or economically feasible.

MANUFACTURING RISKS
 
    If the Company successfully completes development and begins production, it
intends to rely to a large extent on outside vendors to manufacture its engine
components. There can be no assurance of timely availability of products to
satisfy the Company's volume and quality requirements.
 
WARRANTY CLAIMS
 
    RODI has designed the HT1-450 to be a highly reliable engine that should
perform as well as competing products. The significantly lower number of parts
is anticipated to result in less part failures than standard six cylinder
engines. However, extended testing and actual in-service performance must occur
before this reliability is proven, and there is no assurance that this
reliability will actually result.
 
NEED TO ESTABLISH SERVICE CENTERS
 
    There are presently no service centers for the HT1-450 or the HT2-300G. In
order to successfully compete with other products, particularly diesel engines
used in class 8 heavy trucks, the Company will need to maintain service centers
for its products in the geographic markets where it will compete. The Company is
currently considering a number of options in this regard, including joint
ventures with more established companies or establishing relationships with
existing independent service centers. See "Business--Marketing Plan."
 
UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS
 
    The Company relies on trade secrets and proprietary know-how which it seeks
to protect, in part, through confidentiality agreements with employees,
consultants, and others. There can be no assurance that these agreements will
not be breached, that the Company will have adequate remedies for any such
breach or that the Company's trade secrets will not otherwise become known or be
independently developed by competitors, or obtained by competitors through
reverse engineering. Although consultants are not given access to proprietary
trade secrets and know-how of the Company until they have executed
confidentiality agreements, these agreements may be breached by the other party
thereto or may otherwise be of limited effectiveness or enforceability.
 
    The Company has applied for patents on certain aspects of the HT1-450
engine, including certain engine components. However, many aspects of engine
technology, including the reverse uniflow engine cycle, are not believed to be
patentable. No assurance can be given that the Company's patent applications
will be approved or that any issued patents will provide competitive advantages
for the Company's products, or will not be challenged or circumvented by
competitors.
 
ENVIRONMENTAL REGULATIONS AND CONCERNS
 
    Although the HT1-450 is designed to meet the new 1998 emissions regulations,
additional testing and development is required to verify RODI's expectations.
Future environmental legislation and resulting regulations may adversely affect
RODI's ability to manufacture and deliver engines and related products. See
"Business--Governmental Regulation."
 
DETERMINATION OF OFFERING PRICE
 
    The offering price of $4.00 per Unit has been arbitrarily determined by the
Company based on several factors including but not limited to: funds required by
the Company to complete development of the HT1-450 and HT2-300G engines, the
percentage of ownership of the Company to be held by investors in this Offering,
the experience of the Company's management and the current conditions in the
securities markets. Accordingly, there is no relationship whatsoever between the
offering price and the assets,
 
                                       11
<PAGE>
earnings or book value of the Company, or any other recognized valuation
criteria of value. See "Underwriting".
 
NO DIVIDENDS ANTICIPATED
 
    The Company has never paid dividends on its Common Stock and does not
anticipate payment of dividends in the foreseeable future. In this regard, the
Company intends to retain earnings for the foreseeable future for use in the
operation and expansion of its business. See "Dividend Policy".
 
IMMEDIATE SUBSTANTIAL DILUTION
 
    The current shareholders of the Company acquired their shares of Common
Stock of the Company in exchange for nominal consideration or for consideration
which is substantially less than the amount of consideration the purchasers in
this Offering will pay for their shares. As a result, new investors in this
Offering will bear a substantially greater share of the risks inherent in an
investment in the Company. The Company's net tangible book value as of April 30,
1997 was ($197,576) or ($.02) per share and will increase to approximately
$3,082,424 or $.23 per share, if the minimum number of Units are sold, and
$17,002,424 or $0.97 per share, if the maximum number of Units are sold. The
result will be an immediate and substantial dilution of the net tangible book
value of the shares of Common Stock acquired by the public investor of ($3.77)
per share if the minimum number of Units offered hereby are sold and ($3.03) per
share if the maximum number of Units are sold. See "Dilution."
 
PRICE VOLATILITY
 
    The securities markets have from time to time experienced significant price
and volume fluctuations that may be unrelated to the operating performance of
particular companies. In addition, the market prices of the common stock of many
publicly traded development stage companies have in the past been, and can in
the future be expected to be, especially volatile. Announcements of
technological innovations or new products by the Company or its competitors,
developments or disputes concerning patents or proprietary rights, publicity
regarding actual or potential results relating to products under development by
the Company or its competitors, regulatory developments in both the United
States and foreign countries, delays in the Company's testing and development
schedules, and other external factors, as well as period to-period fluctuations
in the Company's financial results, may have a significant impact on the market
price of the Common Stock.
 
POTENTIAL ADVERSE EFFECT OF UNDERWRITER'S WARRANTS
 
    At the consummation of the Offering, the Company will sell to the
Underwriter for nominal consideration the Underwriter's Warrants to purchase up
to 100,000 shares of Common Stock. The Underwriter's Warrants will be
exercisable for a period of four years commencing one year after the effective
date of this Offering, at an exercise price of $5.00 per share. For the term of
the Underwriter's Warrants, the holders thereof will have, at nominal cost, the
opportunity to profit from a rise in the market price of the Common Stock
without assuming the risk of ownership, with a resulting dilution in the
interest of other security holders. As long as the Underwriter's Warrants remain
unexercised, the Company's ability to obtain additional capital may be adversely
affected. Moreover, the Underwriter may be expected to exercise the
Underwriter's Warrants at a time when the Company would, in all likelihood, be
able to obtain any needed capital through a new offering of its securities on
terms more favorable to the Company than those provided by the Underwriter's
Warrants. See "Underwriting."
 
POTENTIAL ADVERSE EFFECT OF REDEMPTION OF STOCKHOLDER WARRANTS
 
    Commencing       , 1998 [12 months after the date of this Prospectus], the
Warrants are subject to redemption at $0.05 per Warrant on 30 days' prior
written notice to the Warrant holders if the average
 
                                       12
<PAGE>
closing sales price of the Common Stock as reported on NASDAQ equals or exceeds
$7.50 per share for any 20 trading days within a period of 30 consecutive
trading days ending on the fifth trading day prior to the date of the notice of
redemption. If the Warrants are redeemed, holders of the Warrants will lose
their rights to exercise the Warrants after the expiration of the 30 day notice
of redemption period. Upon receipt of a notice of redemption, holders would be
required to: (i) exercise the Warrants and pay the exercise price at a time when
it may be disadvantageous for them to do so, (ii) sell the Warrants at the
current market price, if any, when they might otherwise wish to hold the
Warrants or (iii) accept the redemption price, which is likely to be
substantially less than the market value of the Warrants at the time of
redemption. See "Description of Units."
 
COMMON STOCK OPTIONS
 
    The Company has reserved 6,000,000 shares of its Common Stock under the
Company's Incentive Stock Option Plan, of which options to purchase 4,755,309
have been granted at exercise prices ranging from $0.15 to $1.10 per share. If
all such options were exercised upon completion of this Offering, the Company's
net tangible book value would increase from ($197,576) or ($0.02) per share on
April 30, 1997, to approximately $7,257,914 or $0.40 per share if the minimum
number of Units are sold and $21,171,914 or $0.95 per share if the maximum
number of Units are sold. For the term of the options, the holders thereof will
have, at nominal cost, the opportunity to profit from a rise in the market price
of the Common Stock without assuming the risk of ownership, with a resulting
dilution in the interest of other security holders. As long as the options
remain unexercised, the Company's ability to obtain additional capital may be
adversely affected. Moreover, the optionees may be expected to exercise the
options at a time when the Company would, in all likelihood, be able to obtain
any needed capital through a new offering of its securities on terms more
favorable to the Company than those provided by the options. See
"Management--1992 Incentive Stock Option Plan", and "Dilution".
 
ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK
 
    The Articles of Incorporation of the Company currently authorize the Board
of Directors to issue up to 30,000,000 shares of Common Stock. The power of the
Board of Directors to issue shares of Common Stock or warrants to purchase
shares of Common Stock is subject to shareholder approval in only limited
instances. Accordingly, any additional issuance of the Company's Common Stock
may have the effect of further diluting the equity interest of shareholders. See
"Description of Capital Stock."
 
CONTROL BY EXISTING MANAGEMENT AND SHAREHOLDERS
 
    Following completion of this Offering, the Company's present shareholders
will own more than fifty percent of the Company's issued and outstanding stock
if the Minimum Amount is sold, and will likely own a controlling interest in the
Company if the Maximum Amount is sold. Even though all holders of Common Stock
are entitled to cumulate their shares when voting for directors, the present
shareholders may control sufficient shares to elect most or all members of the
Board of Directors and thereby control the management of the Company. See
"Management," "Principal Shareholders" and "Description of Capital Stock."
 
ESCROW OF INVESTORS' FUNDS
 
    Under the terms of this Offering, the Company is offering the Units on a
"1,000,000 Units, all or none, best efforts" basis, and if the minimum number of
Units offered hereby are sold, the remaining 4,000,000 Units will be offered on
a "best efforts" basis until all of the Units are sold or the offering period
ends, whichever first occurs, unless the offering is terminated earlier by the
Company. No commitment exists by anyone to purchase all or any part of the
Units. Consequently, there is no assurance that the minimum number of Units
being offered will be sold, and subscribers' funds may be escrowed for as long
as 190 days (the 90 day offering period, which may be extended by an additional
90 days, plus an additional
 
                                       13
<PAGE>
10 business days to permit clearance of funds in escrow) and then returned
without interest thereon, in the event the minimum number of Units offered
hereby are not sold within the offering period. Accordingly, investors will not
have the use of their subscription funds during this period. In the event the
Company is unable to sell the minimum number of Units offered hereby within the
Offering period, the Offering will be terminated. See "Underwriting".
 
DIRECTORS' AND OFFICERS' LIABILITY LIMITED.
 
    Under Washington law, the Company is required to indemnify its officers and
directors against liability to the Company or its stockholders in any proceeding
in which the officer or director wholly prevails on the merits. Generally, the
Company may indemnify its officers and directors against such liability if the
officer or director acted in good faith believing his or her actions to be in
the best interests of the Company, unless the director or officer is adjudged
liable to the Company. See "Management-- Limitation on the Liability of
Directors".
 
SHARES AVAILABLE FOR RESALE
 
    As of May 31, 1997, there were 12,673,085 shares of Common Stock
outstanding. Such shares of Common Stock have not been registered under the
Securities Act, and are "restricted securities" under Rule 144 of the Securities
Act. In general, under Rule 144, a person (or persons who agree to act in
concert) who owns "restricted securities" or who is an "affiliate" of the
Company, after holding such securities for a period of one year, will be able to
sell within any three-month period an amount of shares of Common Stock equal to
the greater of (i) 1% of the number of outstanding shares of Common Stock of the
Company, or (ii) the average weekly reported trading volume of the shares of
Common Stock for the four weeks preceding such sale. A person who is not an
affiliate for three months prior to the sale may, after holding "restricted
securities" for two years, sell such securities without being subject to the
foregoing volume limitation. Of these 12,582,085 shares outstanding as of May
31, 1997, 12,065,423 shares have been owned for between one and two years and
will be eligible for resale upon compliance with the volume limitations of Rule
144; 11,366,878 of these outstanding shares have been owned for more than two
years and will be eligible for resale without restriction upon completion of the
Offering, subject only to the Rule 144 volume limitations for shares held by
affiliates. Of the 12,587,085 shares outstanding, 6,645,978 are owned by
affiliates and will be subject to Lock-up Agreements upon completion of the
Offering. These affiliates have entered into Lock-Up Agreements with the
Underwriter which prohibit these affiliates for a period of       months from
the effective date of the Offering from the trading in the Company's securities
owned by them without the prior written consent of the Underwriter. The eventual
sale of a substantial number of such shares of the Company's Common Stock
pursuant to Rule 144 could have an adverse effect on the market for or market
price of the Common Stock should such public market develop. See "Principal
Shareholders," "Shares Eligible for Future Sale" and "Underwriting."
 
CURRENT PROSPECTUS AND STATE BLUE SKY REQUIREMENTS REQUIRED TO EXERCISE WARRANTS
 
    The Warrants are not exercisable unless, at the time of exercise, the
Company has a current prospectus covering the shares of Common Stock issuable
upon exercise of the Warrants and such shares have been registered, qualified or
deemed to be exempt under the securities or "blue sky" laws of the state of
residence of the exercising holder of the Warrants. Although the Company has
undertaken to use its best efforts to have all of the shares of Common Stock
issuable upon exercise of the Warrants registered or qualified on or before the
exercise date and to maintain a current prospectus relating thereto until the
expiration of the Warrants, there is no assurance that it will be able to do so.
The value of the Warrants may be greatly reduced if a current prospectus
covering the Common Stock issuable upon the exercise of the Warrants is not kept
effective or if such Common Stock is not qualified or exempt from qualification
in the states in which the holders of the Warrants reside. Until completion of
this Offering, the Common Stock and the Warrants may only be purchased together
on the basis of one share of Common Stock and
 
                                       14
<PAGE>
one Warrant, but the Warrants will be separately tradeable immediately after
this Offering. Although the Securities will not knowingly be sold to purchasers
in jurisdictions in which the Securities are not registered or otherwise
qualified for sale, investors may purchase the Warrants in the secondary market
or move to a jurisdiction in which the shares underlying the Warrants are not
registered or qualified during the period that the Warrants are exercisable. The
Company will be unable to issue shares to those persons desiring to exercise
their Warrants unless and until the shares are qualified for sale in
jurisdictions in which such purchasers reside, or an exemption from such
qualification exists in such jurisdictions, and holders of the Warrants would
have no choice but to attempt to sell the Warrants in a jurisdiction where such
sale is permissible or allow them to expire unexercised. See "Description of
Securities--Warrants.
 
POSSIBLE ABSENCE OF TRADING MARKET
 
    The Common Stock and the Warrants will be eligible for initial quotation on
the NASDAQ SmallCap Market upon completion of this Offering if the Minimum
Amount is raised and the NASDAQ National Market if the Maximum Amount is raised.
The NASDAQ SmallCap Market may be significantly less liquid than the NASDAQ
National Market. Moreover, if the Company should continue to experience losses
from operations, it may be unable to maintain the standards for continued
quotation on NASDAQ, and the Common Stock and the Warrants could be subject to
removal therefrom. If such removal were to occur, trading, if any, in the Common
Stock and the Warrants henceforth would be conducted in the over-the-counter
market on an electronic bulletin board established for securities that do not
meet the listing requirements for NASDAQ, or in what are commonly referred to as
the "pink sheets." As a result, an investor would find it more difficult to
dispose of, or to obtain accurate quotations for the price of, the Company's
securities. In addition, such removal would subject the Company's securities to
so-called "penny stock" rules that impose additional sales practice and market
making requirements on broker-dealers who sell and/or make a market in such
securities. Consequently, removal from NASDAQ could affect the ability or
willingness of broker-dealers to sell and/or make a market in the Company's
securities and the ability of purchasers of the Company's securities to sell
their securities in the secondary market.
 
ABSENCE OF PUBLIC MARKET
 
    Prior to this Offering, there has been no public market for the Company's
Common Stock and Warrants, and there can be no assurance that a trading market
for the Company's Common Stock or Warrants will develop after this Offering, or
if developed, that it will be developed into something greater than a limited
market.

                                USE OF PROCEEDS
 
    The estimated net proceeds to the Company from the sale of Units, after
deducting underwriting commissions and Offering expenses, will be $3,280,000 if
the Minimum Amount of Units are sold (1,000,000) and $17,200,000 if the Maximum
Amount of Units are sold (5,000,000). The following table sets forth the
estimated application by the Company of the proceeds of this Offering.

(1) Approximately $300,000 will be used to advertise and market the Company's

(2) See "Business--The Development Program."
 
(3) If the Maximum Amount is raised in the Offering, the Company intends to
    lease and equip an assembly facility for its engine products. See
    "Business--Research and Development."
 
    Management projects that the net proceeds from the sale of the Maximum
Amount will be sufficient to fund completion of development of the HT1-450 and
HT2-300G engines and provide working capital requirements for approximately 16
months following completion of the Offering. After such 16 month period, the
Company believes that it may be able to finance its operations from internally
generated revenues, assuming the successful completion of development. However,
unless the Company can internally generate sufficient funds, additional
financing will be required to enable the Company to maintain its activities. If
the Minimum Amount of Units are sold, the Company believes that it will have
sufficient funds to complete the HT1-450 engine development, but at a much
slower pace (30 months) due to continued use of part time personnel, fewer test
engines, and without the benefit of additional facilities and test equipment.
There are no assurances that internally generated funds will be sufficient, or
that additional capital, if needed, will be available, or if available, will be
on terms favorable to the Company. See "Risk Factors--Need for Additional
Financing."
 
    Pending the expenditure of the proceeds of this Offering, the Company may
make temporary investments in certificates of deposit, short term
interest-bearing deposits or United States Government obligations.
 
                                DIVIDEND POLICY
 
    The Company has never declared any cash dividends on its Common Stock and
does not intend to declare dividends on its Common Stock in the foreseeable
future. The Company presently expects to retain its earnings to finance the
development and expansion of its business. The payment by the Company of
dividends, if any, on its Common Stock in the future is subject to the
discretion of the Board of Directors and will depend on the Company's earnings,
financial condition, capital requirements and other relevant factors. See
"Description of Capital Stock."

                                    DILUTION
 
    At May 31, 1997, there were 12,587,085 shares of the Company's Common Stock
outstanding having a net tangible book value of ($197,576) or approximately
($0.02) per share. Net tangible book value per share is the net tangible assets
of the Company (total assets less total liabilities and intangible assets)
divided by the number of shares of Common Stock outstanding.
 
    After giving effect to the sale of a minimum of 1,000,000 Units (the minimum
number of Units offered hereby) and a maximum of 5,000,000 Units (the maximum
number of Units offered hereby) at a price of $4.00 per Unit and the application
of net proceeds therefrom (after deduction of estimated offering expenses), the
pro forma net tangible book value of the Company's outstanding Common Stock
would be approximately $0.23 per share if the Minimum Amount of Units are sold
and approximately $0.97 per share if the Maximum Amount of Units are sold.
 
    This represents an immediate increase in the net tangible book value of the
Company's issued and outstanding Common Stock for existing shareholders of
approximately $0.25 per share if the minimum number of Units are sold, and
approximately $0.99 per share if the maximum number of Units are sold and an
immediate dilution to investors purchasing of approximately ($3.77) per share if
the minimum number of Units are sold, and approximately ($3.03) per share if the
maximum number of Units are sold.
 
    Dilution represents the difference between the Offering price of the Units
and the pro forma net tangible book value per share of outstanding shares of
Common Stock of the Company immediately after the completion of this Offering.
Dilution arises mainly from (1) the arbitrary determination of the offering
price by the Company and the Underwriter at a level significantly higher than
the present book value of the Common Stock, and (2) payment of expenses incurred
in connection with the Offering.
 
    The following table illustrates the per share dilution in net tangible book
value as described above if the minimum and the maximum number of Units offered
hereby are sold:

issuance of up to 4,624,559 additional shares of the Company's Common Stock upon
exercise of options which have been granted under the Stock Option Plan. The
issuance of shares of the Company's Common Stock upon the exercise of options
which are granted under the Stock Option Plan would result in further dilution
in the interests of stockholders if at the time of exercise the Company's net
tangible book value per share is greater than the exercise price of any such
options. See "Management--1992 Incentive Stock Option Plan".
 
    In addition, the Company has agreed to sell to the Underwriter warrants to
purchase the Company's Common Stock in an amount equal to two percent (2%) of
the Common Stock sold by the Underwriter (or participating underwriters or
broker-dealers) in the Offering, which Warrants may be exercised during a

four (4) year period commencing on that date which is twelve (12) months after
the date of this Prospectus. The exercise price of such shares is $5.00 per
share. Issuance of the shares subject to such warrants would result in further
dilution of stockholders' interests if at the time of exercise the net tangible
book value of the Company's Common Stock exceeds $5.00 per share. The above
table does not give effect to issuance of any shares upon exercise of such
warrants.
 
    The following tables summarize, on a pro forma basis as of April 30, 1997,
the difference between the
number of shares of Common Stock purchased from the Company, the total
consideration paid and the average price per share paid by existing stockholders
and by the new investors (before deducting the estimated Underwriting
commissions and offering expenses payable by the Company) if the minimum and
maximum number of Units are sold. The table assumes a hypothetical purchase
price of $3.90 for each share of Common Stock in a Unit, and $.10 for each
Warrant in a Unit.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                             AND PLAN OF OPERATION
 
    The following discussion should be read in conjunction with the consolidated
financial statements and related notes and "Summary Financial Data" included
elsewhere in this Prospectus.
 
GENERAL
 
    The Company was formed in 1987 and is in the development stage. The
Company's principal business is to design, develop and market a family of new
heavy duty diesel and natural gas engines with potential applications in
trucking, marine and stationary power. Since inception, the Company has been
engaged in development of its products and raising capital. The Company has not
initiated any production, manufacturing or sales of its products at this point,
which has resulted in the accumulation of net losses characteristic of a
development stage enterprise.
 
    Although the Company has generated minimal revenues from the sale to APE of
engines purchased from a third party in the first quarter of 1997 and
anticipates that such revenues will increase, the Company has not generated any
revenues to date from the sale of its own products and does not expect to
recognize revenue from the sale of the HT1-450 or HT2-300G any sooner than the
end of 1998. See "Business--APE Joint Venture".
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Since inception, the Company's capital resources have been limited.
Management believes that the limited availability of capital resources has
adversely affected the Company's results of operations or prevented the Company
from taking advantage of certain opportunities. For example, the Company has
been required to take actions such as using more expensive but readily available
components, shipping materials and components by more expensive transit, and
procuring monies on terms less favorable than those that may be available
following this Offering.
 
    Management projects that the net proceeds from the sale of the Maximum
Amount will be sufficient to fund completion of development of the HT1-450 and
HT2-300G engines and provide working capital requirements for approximately
sixteen (16) months. After such 16 month period, the Company believes that it
may be able to finance its operations from internally generated revenues,
assuming the successful completion of development. However, unless the Company
can internally generate sufficient funds, additional financing will be required
to enable the Company to maintain its activities. If the Minimum Amount of Units
are sold, the Company believes that it will have sufficient funds to complete
the HT1-450 and HT2-300G engine development, but at a much slower pace (30
months) due to continued use of part time personnel, fewer test engines, and
without the benefit of additional facilities and test equipment. There are no
assurances that internally generated funds will be sufficient, or that
additional capital, if needed, will be available, or if available, will be on
terms favorable to the Company. The Company presently has no credit facilities
or any other commitments to provide capital. See "Risk Factors--Need for
Additional Financing."
 
    Over the next twelve (12) months, the Company's operations will be focused
primarily on completing the development program previously defined for the
HT1-450 diesel engine and the HT2-300G natural gas engine. In addition to funds
obtained from the Offering, the Company intends to seek funding from the Natural
Gas Institute, the U.S. Department of Energy and from several major natural gas
suppliers through Alternate Power Equipment, Inc. in risk sharing
engine/generator development programs. However, there are no assurances that
such funding will be available.
 
    In addition to completion of the development of the HT1-450 and HT2-300G
engines, new research and development activities planned for the next 12 months
include:
 
    1.  An electro-hydraulic engine valve actuation system that eliminates wear
related adjustment.
 
                                       20
<PAGE>
    2.  A high pressure natural gas fuel injection system.
 
    3.  Further work on polyalphaolefin based engine lubricant/coolants.
 
    If the Maximum Amount is sold, the Company expects to purchase a limited
quantity of computer numerical controlled machine tools to assure that a
sufficient quantity of key proprietary components can be fabricated in-house to
support production start-up.
 
    To facilitate the increase in operations if the Maximum Amount is sold, the
Company expects to increase full time employment from the present 7 to 16,
including a senior executive from the automotive industry to head manufacturing
operations and a senior engineer from an engine competitor to complete engine
development.
 
    If the Minimum Amount is sold, the Company would continue to outsource the
majority of the engine components and manufacture only the key proprietary
components in-house. The Company would increase the number of full time
employees from 7 to 11, including the senior engineer, to complete engine
development. The Company would acquire only minimal additional space and test
equipment and continue to use part time personnel to complete the development
program over an extended period of time (30 months versus 16 months).
 
    For further information regarding the Company's proposed plan of operation
see "Business" herein.

                                    BUSINESS
 
GENERAL
 
    RODI Power Systems, Inc. is a development stage company whose first product,
the HT1-450 turbo diesel engine, is in the development stage. If the HT1-450 is
successfully developed, the Company intends to manufacture, market, and sell
this engine, as well as derivative engines based on this technology and related
components and accessories world wide. The Company also intends to manufacture,
market and sell the HT2-300G four-stroke cycle natural gas fueled engine
currently under development, regardless of the success of the HT1-450 engine.
There are no assurances, however, that development of these products will be
successfully completed. The Company is an equal partner in a three way joint
venture, Alternate Power Equipment, Inc., which recently commenced manufacturing
diesel/electric stationary power systems using Deere PowerTech engines.
 
PRODUCT DESCRIPTION
 
    RODI is developing a two cylinder turbocharged power module which can be
packaged into a variety of forms; I-2, V-4, I-4, I-6, V-8 and V-12. The first
engine, the HT1-450 turbo diesel engine, is a V-4 engine which is substantially
lighter in weight and shorter in length than its competitors when constructed
from identical materials. It is designed to be a replacement for the I-6
cylinder CAT 3406, Detroit S60 and Cummins N14 series of engines which produce
350 to 500 hp and weigh approximately 2700 lbs with no accessories, coolant or
oil. These engines, intended primarily for the class 8 heavy truck market, are
also used extensively in stationary and marine applications, such as power
generation, pumping and refrigeration. The HT1-450 is expected to have an
advantage in each competitive category: lower fuel consumption (approximately 40
hp less internal friction at 1800 rpm), higher low speed torque, lower weight
and lower structural loading for longer life. A tabulation of the physical
attributes of each engine is shown in the section below entitled "Competition."
 
    The turbocharged two cylinder power module is based on two enabling
technologies currently under development by RODI, the reverse uniflow two-stroke
engine cycle and the two point microprocessor engine control and its associated
interactive software. Patents are currently pending on two technologies: a
unique piston design and a valve train mechanism which has application to all
internal combustion engines. See "Business--Patents and Proprietary Rights."
 
    In the reverse uniflow two-stroke cycle, pressurized air is admitted via
intake valves located in the cylinder head and exhaust is discharged through
ports machined into the lower extremity of each cylinder liner. This eliminates
the need for exhaust valves while still achieving efficient scavenging of the
exhaust within the cylinders.
 
    The two point microprocessor engine control under development is designed to
permit initiation and termination of fuel delivery to be programmed
independently for each individual cylinder. The control system computer is
designed to continuously monitor and control all engine functions to optimize
operating efficiency. An integral cellular telephone/modem capability will be
designed into the control system to enable the engine's operator to receive
diagnostic or repair assistance from a factory service specialist at any time.
The service specialist will be able to operate/adjust the engine by remote
control.
 
    The benefit of a V-4 over an I-6 configuration includes reducing the number
of main bearings from seven to three and the length of the crankshaft by 45%. A
proportional reduction in component count is reflected throughout the engine
resulting in approximately 40% fewer parts and hence significantly lowering the
cost of production. Another significant difference between the HT1-450 and its
four-stroke competitors is the absence of exhaust valves and related heating of
the head. The single greatest failure mechanism of diesel engines is exhaust
valve induced failure of the head. The heat normally lost to the head's coolant
in competing engines is harnessed by two turbochargers in the HT1-450. Each
turbocharger
 
                                       22
<PAGE>
is connected to a pair of cylinders on one bank of the V, allowing either half
of the engine to operate independently of the other, improving fuel consumption
when lightly loaded as during an empty backhaul.
 
    If development is successful, the fuel delivered to each cylinder will be
individually controlled by the two-point microprocessor. Combustion research has
established a definite relationship between piston speed (engine rpm) and
initiation of fuel delivery for optimum performance. By adjusting the initiation
point and period of fuel delivery to engine speed, smoother operation is
possible as are reduced exhaust emissions. The control system can be programmed
to run the engine on either bank of the V, resulting in a 15% reduction in fuel
consumption during that portion of operation. This operating feature is not
presently available on any of the competing engines. The microprocessor also
provides cruise control, vehicle speed limiting, dynamic braking, emergency
shutdown, automatic ether start in cold weather, progressive shifting prompts
and diagnostic outputs.
 
    Synthetic oil (polyalphaolefin) is used for both lubrication and cooling. In
competing water cooled engines, coolant seal leakage resulting in oil
contamination is a common cause of premature engine failure. In addition,
synthetic oil can safely be used at temperatures in excess of 240 degrees
Fahrenheit whereas water/glycol mixtures are limited to 215 degrees. Higher
coolant temperatures permit the use of a relatively smaller heat exchanger
(radiator) and improved fuel economy. Using synthetic oil as a coolant also
eliminates the risk of freeze damage to the cylinder block and head. Disposal of
contaminated water/glycol coolant is also eliminated since synthetic oil can be
recycled and reused at minimal cost. Engine braking is provided by a hydraulic
retarder feature integral with the oil pump. Additional braking is provided by
the engine fan whose clutch is automatically engaged when the truck brakes are
activated. The combined braking capacity is approximately 100 horsepower with
reduced noise levels.
 
    The HT1-450 has a cylinder bore and stroke (6.25 x 6.82) which is slightly
larger than that used by its four-stroke cycle competitors. Since each piston
has a power stroke on each revolution of the crankshaft, the 4 cylinder engine
has an effective volumetric displacement of 587 cubic inches. The four-stroke 6
cylinder competitors have a power stroke on alternate revolutions of the
crankshaft and have an effective volumetric displacement of 385 to 447 cubic
inches. The two-stroke cycle also creates a flatter torque curve which
significantly increases high rpm pulling capacity, permitting the replacement of
standard 9 and 12 speed transmissions with a lighter, lower cost 7 speed unit or
enabling the use of a higher speed rear axle. The cylinder block, cylinder head,
crankshaft and connecting rods currently under development are designed to
withstand increased output power to as much as 650 hp. The production HT1-450 is
expected to weigh less than 2,000 lbs which is significantly less than the
competing engines.
 
    The HT2-300G uses approximately 80% of the HT1-450's components; differing
primarily in the cylinder head, cylinder liners, pistons, fuel control and
simplified accessory drive system. The four-stroke engine cycle limits the
effective volumetric displacement to 418 cubic inches but permits the use of
natural aspiration air induction. By using the rugged diesel engine moving parts
and cooling system in combination with natural aspiration air induction and a
10.5:1 compression ratio, the engine is expected to provide trouble free
operation for long periods of time. The production HT2-300G is expected to weigh
less than 2,000 lbs.
 
INDUSTRY ANALYSIS
 
    MARKET SIZE.  The class 8 truck market is relatively stable and very well
documented with 2.3 million trucks registered in 1995. (As reported in THE WALL
STREET JOURNAL and DIESEL PROGRESS MAGAZINE). New truck sales over the last 10
years have varied from 160,000 to 210,000 annually with 1995 production at
205,000 units. The class 8 engine has an average life of 9 years, based on
100,000 miles per year and includes at least one major overhaul. A new engine
may be substituted for an engine rebuild if the added productivity justifies the
additional cost, particularly on trucks with expensive chassis such as concrete
mixers. The market for engines in this power class for alternate applications
(military, marine and stationary) is less well documented but averages
approximately 40,000 annually. The international market for class 8 engines
 
                                       23
<PAGE>
has been small mainly due to the lack of an adequate road infrastructure and the
cost of fuel. This is changing as countries such as Saudi Arabia and Australia
expand their highway systems which created a demand for 28,000 engines in 1995.
These combined markets are conservatively estimated at 373,000 engines in the
350 to 500 hp power class annually with a value of more than $6 billion.
After-market service and spare parts represent a significant and growing portion
of the class 8 engine market, with estimated annual sales of more than $1
billion.
 
    As a result of the deregulation of both the natural gas and electrical power
industries, the demand for both diesel and natural gas fueled electrical power
generation systems is expected to grow dramatically. (As reported to the INGAA
Foundation in 1996 by STONE & WEBSTER MANAGEMENT CONSULTANTS, INC). The use of
remote electrical power generation is particularly important in those regions
where a significant percentage of electrical power consumption is the result of
air conditioning or refrigeration. Sites such as office buildings, shopping
malls, supermarkets and high schools are large consumers of refrigeration and
air conditioning. A high percentage of these sites require from 200 to 600
kilowatts of electrical power during peak consumption periods. In a typical
Southern site where electricity costs $0.07 per Kwh and natural gas costs $3.00
per MCF, savings of up to 40% can be achieved using a natural gas fueled
electrical generator system. The HT2-300G is designed to provide continuous duty
and optimum fuel efficiency at minimum capital cost.
 
    COMPETITION.  The Cummins N14 series, the Cat 3406 series and the Detroit
S60 series of six cylinder in-line diesels are the engines of choice for the
North American class 8 heavy duty truck market. Cummins and Detroit currently
have 35% market shares each and Cat has 30%. No foreign manufacturer has a class
8 engine available in North America that meets customer expectations. Below is a
brief comparison of the competing engines.

<PAGE>
This competitive comparison illustrates the unique advantages that the fully
developed HT1-450 is expected to have:
 
1.  The production HT1-450 is designed to weigh significantly less than its
    lightest competitor when manufactured from the same materials and is ready
    to run. This potentially translates into an average annual profit increase
    of $5,000 or more for trucks operating at maximum gross weight with payloads
    such as fuel, concrete and new automobiles.
 
2.  The HT1-450 is designed to have less internal friction than its best
    competitor which should result in a fuel economy advantage of up to 7.5%
    regardless of application.
 
3.  The HT1-450 is designed to automatically operate on two cylinders during
    periods of low power demand such as a dump truck returning home. This can
    result in significantly less fuel being consumed during that portion of
    operation and may reduce engine wear.
 
4.  Both the HT1-450 and HT2-300G are designed to have 40% fewer parts to
    manufacture, break or wear out. The initial cost of the engines and
    overhauls, when necessary, are expected to be much less expensive than the
    big three competitors' engines.
 
5.  The HT1-450 power head is designed to be removed from a class 8 truck and
    replaced in about 4 hours. This will permit most major repairs to be made
    more efficiently out of the truck rather than the "in-frame" repairs
    normally performed on the competitor's engines. The loss of an additional 16
    to 20 hours of hauling time, when comparing a RODI repair with competitors,
    costs the operator up to 12,000 ton miles in lost revenues. In 1994 the
    average freight rate was $1.84 per ton mile and the average payload was 12
    tons, at an average highway speed of 50 mph, this would result in a revenue
    differential penalty of $17,664 for a single engine breakdown that kept the
    truck from moving for 16 hours more than the HT1-450 equipped vehicle.
 
    Aftermarket parts suppliers and local overhaul specialists have captured a
significant percentage of the North American class 8 engine non-warranty service
and parts business. These companies are aided in their market penetration by the
warranties and speed of service of the engine manufacturer's local dealers. RODI
has crafted a warranty and service plan intended to capture a significant
portion of the aftermarket parts and service business for the HT1-450. Engine
power head removal/replacement has been designed to be a simple process which
can be accomplished in about 4 hours. Because the HT1-450 power head is lighter
in weight, less expensive service trucks and handling systems may be employed
for roadside repairs. By making engine replacement a viable option and
remanufactured engines affordable, RODI expects to retain more control of
aftermarket parts and service.
 
MARKETING PLAN
 
    RODI's marketing strategy is based on customer demand "pull through" with
the truck and generator set manufacturers. RODI has been working directly with
selected customers and a truck and generator set manufacturer to integrate their
requirements into the basic engine design. Because of its small size, the
HT1-450 can be installed in most currently available heavy duty trucks. Newly
designed trucks may take full advantage of the lighter weight and more compact
size of the HT1-450. If sufficient funding is available and the development
program is successful, the first RODI engine for testing in the generator set
application is expected to be delivered in 1998.
 
    RODI intends to develop replacement engine retrofit kits for the most
popular class 8 trucks. By offering the hardware required to upgrade trucks with
worn engines that are otherwise sound, the customer has a choice of repowering
rather than replacing the entire truck. The typical 5 year old class 8 truck has
accumulated 500,000 miles and requires either a full "in frame" engine rebuild
or a replacement engine to continue reliable service. Trucks in this condition
are generally fully amortized but retain a resale value of approximately $25,000
plus the value of the payload system. By substituting a RODI HT1-450 for the old
engine and replacing wear items such as brakes and universal joints, the value
of the truck is significantly increased at a much lower cost than that
associated with conventional engines.
 
                                       25
<PAGE>
    Many of the larger carriers prefer to trade in their used trucks and
purchase new ones before major repairs are required. RODI has identified and has
been working directly with several such carriers in the Pacific Northwest as
well as a limited number in other areas of North America
 
    Upon successful development of the HT1-450 engine, the primary thrust of
RODI's marketing effort will initially be directed at capturing a significant
market share in the Pacific Northwest, and then in the Gulf Coast regions. The
initial emphasis for truck engine sales is on Washington, Oregon, Idaho and
British Columbia whose proximity to RODI simplifies communications and sales and
service support while the program is being perfected. Kenworth, Freightliner and
Western Star have truck assembly plants within 200 miles of RODI's headquarters
in Kent, Washington. Due to the relative prosperity of the Pacific Northwest,
market predictions for the local area are more favorable than North America as a
whole. With the exception of logging trucks, all segments of the local market
are expanding; resulting in a minimum predicted market of 12,000 new trucks
annually and a similar quantity of remanufactured engines. A conservative
estimate for total 1997 engine sales for class 8 trucks in the Pacific Northwest
is $575 million based on the reported plans of Freightliner and Kenworth.
 
    Two key customer types have been targeted for initial truck engine sales
efforts, the high gross weight haulers and the medium size regional general
freight lines. In this expanding economic area, the transport of fuel, gravel,
concrete and new cars represent the fastest growing market segments with more
than 8000 units sold in 1995 based on license applications to Washington
Department of Motor Vehicles. Since these vehicles typically go out at maximum
gross weight and return empty, they are prime candidates for the HT1-450's added
payload and low cost back haul capability.
 
    The ports of Seattle/Tacoma, Portland and Vancouver, B.C. handle a major
portion of the Pacific rim shipping which is then trucked throughout the Western
states by more than 200 regional truck lines. (SOURCE: WESTERN WASHINGTON YELLOW
PAGES) Freight carriers such as Oak Harbor Freight and Okanagan Seattle
Transport operate a significant number of trucks exclusively within the Pacific
Northwest, many of which operate at maximum gross weight most of the time. These
200 carriers presently own and operate nearly 28,000 trucks and are expected to
continue growing.
 
    The Gulf Coast was chosen due to the presence of the Peterbilt and Marman
truck plants near Dallas and the large U.S./Mexico truck fleet operations
resulting from NAFTA; the location of Alternate Power Equipment, Inc. in Alvin,
Texas; and the large number of marine operators in the area.
 
    RODI recently began to study the market for a natural gas fueled derivative
engine-generator system specifically for interruptible electrical load
management in heavy commercial and light industrial applications. The primary
customers for this system would be the major natural gas distribution companies
who intend to provide an alternate source of electrical power to their customers
during peak electrical usage periods. This period is generally during the summer
months when air conditioning greatly increases demand for electrical power and
natural gas demand, used primarily for space heating, is at its lowest point.
The customer is expected to reduce the cost of peak demand electrical power by
up to 40% and the gas utilities are expected to increase summer revenues by up
to 50%. Preliminary market studies by RODI indicate that there are more than
300,000 sites where this system would be economically viable with each site
requiring 2 to 6 engine-generator sets. This market is conservatively estimated
by RODI at $14 billion over 10 years. In addition to the 300 kw HT2-300G, the
Company expects to market a 7.6 liter 150 kw Deere natural gas engine being
developed for the same application. The first 7.6 liter Deere natural gas
engines are expected to be available in the fourth quarter of 1997.
 
APE JOINT VENTURE
 
    In 1997 the Company formed a joint venture called Alternate Power Equipment,
Inc. ("APE") with Alternate Power Technology, Inc. and N.R. Broussard Landing,
Inc. APE was formed to design, fabricate and market diesel/electric, natural
gas/electric and line shaft stationary power systems with prime ratings from 40
to 400 kw. These heavy duty systems are intended primarily for applications such
as petroleum
 
                                       26
<PAGE>
drilling and continuous duty lighting at remote sites. Under the terms of the
venture agreement, RODI is responsible for furnishing to APE internal combustion
engines and controls, and engineering and manufacturing support. Initially,
engines supplied by RODI will be obtained from John Deere on an OEM basis. The
other venture partners are responsible for the assembly of the products, and
marketing and distribution. Under the terms of the venture agreement RODI is
entitled to a percentage markup on equipment supplied to APE, and the other
venture partners are required to furnish certain services to APE on a basis
intended to allow them to recoup their costs plus a reasonable profit margin.
Profits of APE are shared equally by the venture partners. A customer has
advised APE that it intends to order 49 units upon successful completion of
testing.
 
THE DEVELOPMENT PROGRAM
 
    CURRENT STATUS OF HTI-450 ENGINE
 
    RODI has fabricated and extensively tested three prototype models of the
HT1-450 diesel engine. These engines have satisfactorily completed the following
design and performance parameters: validation of the reverse uniflow cycle,
dynamic balancing, structural adequacy, fuel injection, intake valve timing and
piston and piston ring configuration. These three engines have accumulated many
hours of test operation on the Company's dynamometer test stand and limited road
testing in the Company's class 8 heavy truck. Prototype engine fuel efficiency
has been adequate for the power levels tested to date. Further development and
testing will be required to (i) improve cooling capacity, (ii) sustain valve
train operation at 1800 rpm, and (iii) synchronize the exhaust system and the
turbocharger.
 
    Currently tests are planned to enhance performance and increase maximum
power output of the HT1-450 by greatly increasing air flow through the engine by
optimizing air cycle components such as intake valves, exhaust port geometry,
supercharger volume ratio and turbocharger matching. Variables to be tested
include various exhaust system geometry changes; the use of four intake valves
per cylinder and using several types and combinations of supercharger and
turbocharger. Optimizing the air cycle of a two-stroke engine is a complex
trade-off of many characteristics that are interrelated. Recently completed
cylinder liner and piston design changes are believed to have resolved past
problems associated with oil cooling and will be verified by test during the
first phase of the pre-production engine development program.
 
    REPORT OF DAVID T. MARKS
 
    A technical status report on the HT1-450 program prepared by David T. Marks,
an independent engine expert, in January 1997 is attached as Appendix A to this
Prospectus. Mr. Marks was retained by the Company in 1996 in order to obtain an
independent valuation of the HT1-450 engine design. Since the date the report
was issued, the HT1-450 engine has undergone extensive redesign, based in part
upon the suggestions of Mr. Marks. RODI continues to retain Mr. Marks as an
outside consultant.
 
    HT1-450 DEVELOPMENT PROGRAM PLAN
 
    If the Maximum Amount is raised, RODI intends to fabricate 25 preproduction
HT1-450 engines for use in completing the development program. These engines
will be divided into four groups; five engines for component integration
verification testing, five engines for dynamometer endurance testing, five
engines for manufacturing engineering development and ten engines for in-truck
highway testing. If the Minimum Amount is raised RODI intends to fabricate 10
preproduction HT1-450 engines with two engines each for component integration,
dynamometer endurance and manufacturing engineering, and four engines for
in-truck highway testing. These tests will address the following
characteristics:
 
    1.  Component Integration Testing
 
       a.  Valve train performance
 
                                       27

       b.  Oil pumping and oil cooling system
 
       c.  Cylinder liner/Piston/Rings performance
 
       d.  Crankshaft/Rod/Bearing performance
 
       e.  Air cycle performance including supercharger and turbocharger
           selection
 
       f.  Fuel injection system performance
 
       g.  Build 2-cylinder test modules to facilitate development testing
 
    2.  Dynamometer Endurance Testing

    4.  In-Truck Highway Testing
 
       a.  Freightliner, Navistar, Western Star and Kenworth engine installation
 
       b.  Manual 7 and 9 speed transmission versus automatic transmissions
 
       c.  On-engine diagnostic and telemetry systems performance
 
    HT2-300G DEVELOPMENT PROGRAM
 
    The Company believes that the primary competitive advantage of this engine
will be its simplicity, low cost and rugged packaging approach for application
in the stationary power market. The HT2-300G four-stroke engine is based on
fully proven design principals currently in the marketplace.
 
    Although the HT2-300G engine has not yet been fabricated by RODI,
approximately 85% of the engine design is similar to the HT1-450 engine; most of
the remaining details relate to the proven four stroke cycle engine. Design
details remaining to be completed relate to the cylinder head, spark ignition
system, gas control valve and accessory drive. If the Maximum Amount is raised,
RODI intends to fabricate 10 HT2-300G engines for the development program. The
engines will be divided into two groups; four will be used in-house for
dynamometer and direct generator drive testing and six will subsequently have
any design improvements added and then be provided to Alternate Power Equipment,
Inc. for a cooperative test program. If the Minimum Amount is raised, the
HT2-300G development program would assume lower priority to the HT1-450, but
RODI would fabricate two HT2-300G engines for the development program, with one
for in-house testing and one for an APE cooperative test program. These tests
will address the following characteristics:
 
    1.  Component Integration Testing
 
       a.  Exhaust Valve endurance
 
                                       28
<PAGE>
       b.  Gas control valve performance
 
       c.  Spark ignition system optimization
 
    2.  Dynamometer Endurance Testing
 
       a.  Continuous maximum power rating
 
       b.  Fuel efficiency
 
       c.  Exhaust emissions
 
       d.  Low temperature starting
 
       e.  Compatibility with unrefined (wellhead) gas
 
    3.  Manufacturing Engineering Development
 
       a.  Cylinder block and crankshaft development
 
       b.  Cylinder head development
 
       c.  Valve train development
 
    4.  Customer Cooperative Testing
 
       a.  Generation system installation
 
       b.  Synchronous and induction generator matching
 
       c.  On-engine diagnostic and telemetry systems performance
 
GROWTH STRATEGY
 
    The Company believes its principal strengths include (i) its reservoir of
technical talent, (ii) a unique engine cycle and fuel control design, and (iii)
an expanding worldwide demand for similar products.
 
    The Company's growth strategy includes the following key elements:
 
    DEVELOP AND MARKET A COMPLETE PRODUCT LINE OF HEAVY DUTY DIESEL ENGINES.  In
addition to RODI designed and developed engines, the Company currently has OEM
(Original Equipment Manufacturer) rights from John Deere to high quality engines
from 80 hp to 500 hp that will currently be complimented by internally
manufactured products. Assuming successful completion of development, RODI
intends to manufacture engines having from 300 to 2000 horsepower which will
create a full engine product line from 80 to 2000 horsepower.
 
    INITIATE PRODUCTION USING ESTABLISHED SUBCONTRACTOR RESOURCES.  The Company
believes that the most cost effective method of reaching volume production
capacity quickly is to utilize qualified subcontractors, selected through a
process of teaming to produce most engine components. RODI is currently
investigating a number of sites for its initial assembly plant.
 
    NORTH AMERICAN MARKET PENETRATION.  Upon successful development of the
HT1-450 and HT2-300G engines, the Company intends to focus marketing efforts in
North America using field representatives responsible for developing a
Distributor/Dealer sales and service network, a working relationship with the
major users in their region and maintain cooperative relations with the major
truck, stationary power and yacht manufacturers. The Company is presently
seeking other joint venture partners in addition to Alternate Power Equipment,
Inc. to participate in the development and marketing of products to the
industrial power and marine power businesses in the Pacific Rim and European
Economic Community.
 
                                       29
<PAGE>
    INTERNATIONAL EXPANSION.  The Company is seeking strategic alliances or
production licensees in the Pacific Rim and European Economic Community. The
Company presently has an agreement with Japan Transaction Partners in Tokyo,
Japan to represent its interests in that region.
 
OPERATIONS
 
    Presently the high value components of the HT1-450 prototypes are planned to
be wholly subcontracted to qualified suppliers. RODI presently has the in-house
capability of machining several key proprietary components associated with the
reverse uniflow cycle and fuel control system. For the production program, the
high value iron components such as the cylinder block are intended to be cast by
a third party at a foundry located in Mexico in conjunction with several other
heavy duty diesel engine manufacturers to take advantage of the economic
benefits of the NAFTA treaty. These components would then to be shipped into the
United States via the Laredo, Texas port of entry and machined either by
subcontractors or by RODI. The aluminum components are intended to be cast at a
foundry in Texas and machined at an adjacent facility.

                          MANUFACTURING ACTIVITY FLOW
 
RECEIVING
 
    1. Raw materials, unmachined castings and finished components are delivered
to a RECEIVING CELL where they are logged into the on-line data base.
 
    2.  Empty KanBans (tubs on wheels) are retrieved from the Receiving Pending
KanBan holding area, transported to the RECEIVING CELL and loaded with
materials. Each KanBan's bar code is scanned and its contents recorded.
 
    3.  KanBans containing finished components are moved to the BUY STORES CELL,
KanBans containing raw materials and unmachined castings are moved to the RAW
MATERIAL/MFG. STORES CELL. The KanBan's bar code is scanned as it is deposited
in the appropriate holding area.
 
MANUFACTURING/MACHINING
 
    1.  MANUFACTURING CELLS are supplied with the appropriate raw material or
unmachined casting as required by the schedule. Each KanBan enters the
manufacturing area via a Staging Area where the part to be machined is mounted
on a bar coded pallet. The material hand-off from KanBan to pallet is entered
into the on-line data base.
 
    2.  As the MANUFACTURING CELL demands, the appropriate bar coded pallet is
mounted on the machine tool feed and machined with the correct CNC code.
 
    3.  The completed component is returned to the correct KanBan and either
forwarded to MANUFACTURING STORES CELL or delivered to the Spares Staging area
for delivery to a customer as a spare part. As the KanBan's bar code is scanned,
the computer provides a visual and itemized list of its required contents to
assist the machine operator in assuring correct component assignment.
 
ENGINE ASSEMBLY/TEST
 
    1.  Bar coded Engine Carts (batter powered jitneys) are used to transport
all required components to assemble a single engine from MANUFACTURING and BUY
STORES CELLS. The contents of several KanBans are scanned and linked to the
Engine Cart to form a "train".
 
    2.  The Engine Cart "trains" are transported to an ASSEMBLY CELL staging
area.
 
    3.  As the ASSEMBLY CELLS demand, the Engine Cart "trains" are moved to an
ASSEMBLY CELL where the engine is fully assembled. As the components of each
KanBan are consumed, the empty KanBans are returned to the Receiving Pending
KanBan holding area near the RECEIVING CELL by a returning Engine Cart.
 
    4.  The complete engines are marked with a bar code data plate wherein its
entire component pedigree is entered into the computer. The engine is then
attached to a moving overhead transport chain and taken to an engine TEST CELL.
 
    5.  The engine is attached to a dynamometer, its bar code scanned, started
and tested at various power output loads for 20 minutes. This test data is added
to the engine pedigree.
 
    6.  Those engines that successfully pass the test program are reattached to
the overhead transport chain and moved through the paint booth and then to the
Pack/Ship staging area. Those engines that fail the test program are moved to an
adjacent REPAIR CELL where the problem detected is repaired. The engine is then
returned to the Test Cell where a complete test sequence is performed.
 
PACK/SHIP
 
    1.  In the PACK/SHIP CELL tested engines are removed from the overhead
transport chain, their bar code scanned and mounted in a shipping container.
 
    2.  The containerized engines are logged out of the on-line data base and
appropriate ownership and shipping documents generated by the computer.
 
    3.  The containerized engines are loaded onto a vehicle for delivery.
 
                                       31
<PAGE>
    For the production program, RODI intends to use a Flexible Manufacturing
System (FMS) based on the production cell and kanban inventory control process
for engine assembly. The FMS implementation provides a physical assembly cell
containing all required functions for each team. FMS cells have an assembly
capacity of 4 engines per shift each. Each cell will be staffed by 3 employees.
Thus 3 employees will be capable of completing 4 engines daily. The cells will
be put on line in increments matching order bookings. The FMS approach also
enables a rapid training program since one experienced individual can train two
persons at once. By using the latest in high efficiency tooling and equipment,
including robotics where appropriate, RODI intends to maintain production
efficiencies superior to its larger competitors who are saddled with a transfer
line assembly process which cannot easily adjust to volume variations. The
proven advantages of the FMS team approach include process ownership by the
employees which encourages innovation, bottleneck elimination and, most
important, elimination of the expensive and inflexible transfer line which
requires a fixed number of employees and equipment regardless of demand. The
primary benefit to RODI is that it enables incremental increases in production
with a minimum investment.
 
    If the Offering generates sufficient funds, the Company intends to purchase
state-of-the-art Computer Numerical Controlled (CNC) machine tools to fully
manufacture in-house as many of the high cost components as possible. This
facility could be co-located with the assembly plant to minimize transportation
costs.
 
    RODI is developing a computerized network of software modules which will
provide order processing, procurement, inventory control, production control,
engine pedigree documentation, statistical quality information and cost
accumulation and control from a single data base. The system will be expanded to
include on-line service assistance and trouble shooting capability for the
distributor network when required.
 
FACILITIES
 
    The Company's current principal place of business is a 10,000 square foot
combination office, test laboratory and machine shop located at 7503 South 228th
St., Kent, Washington. The Company leases this property on a yearly basis
pursuant to a lease agreement that expires in October 1997. The Company intends
to rent an additional 50,000 square feet of space, either in the same building
complex or nearby, with a portion of the funds received from this Offering to
expand test capability and house a small specialty engine assembly facility. If
the Maximum Amount is sold, the Company is considering a number of potential
sites for its initial assembly facility, including the lease of a 130,000 square
foot military warehouse located on Kelly AFB in San Antonio, Texas, which could
be utilized as a plant capable of assembling up to 100 HT1-450 size engines per
8 hour shift when fully operational.

    No patents have yet been issued on any of the technology used in the HT1-450
engine. The Company currently has an application pending with the U.S. Patent &
Trademark Office for issuance of a patent on a unique piston design and a unique
valve train mechanism which has application in all internal engines.
 
EMPLOYEES
 
    As of May 31, 1997, the Company had 7 full time employees, 16 part time
employees and was utilizing the services of 6 consultants. Of the 23 full and
part time employees, 3 are managers, 2 are machinists and 18 are engineers or
other technical specialists. If the Maximum Amount is raised, the Company
intends to increase headquarters full time employment to 16 including a senior
technical specialist from the heavy duty diesel engine industry. If the Maximum
Amount is sold, the Company intends to employ a senior executive from the
automotive/heavy engine industry to develop and implement a comprehensive
manufacturing plan. If the Minimum Amount is raised, the Company intends to
increase full time employment to 11, including the senior technical specialist,
and continue the use of part time employees. The Company has no collective
bargaining agreements with any of its employees. Most professional and
management employees have stock options as part of their compensation. Company
headquarters is located in close proximity to both The Boeing Co. and Microsoft
and utilizes some of their experts as off hour consultants. The Company believes
that its labor relations are satisfactory and, that its employees are its single
greatest asset.
 
GOVERNMENT REGULATION
 
    Diesel and gas engines are subject to extensive regulatory requirements.
Specific emissions standards for engines are imposed by the U.S. Environmental
Protection Agency ("EPA") and by other regulatory agencies, such as the
California Air Resources Board ("CARB"). These requirements are continually
undergoing changes. The Company's ability to maintain compliance with current
and future emissions requirements is a critical element in commercializing its
engines and establishing the Company's position in the engine marketplace.
Substantial capital and operating expenses may be required to comply with these
emissions requirements and, if the Company is not able to comply, this would
have a material adverse impact on the Company's business and prospects.
 
    The EPA also has an emissions defect reporting program, and may require a
recall if defects are found in emissions-related components on 25 or more
engines. CARB regulations require the Company to report failures of
emissions-related components through the monitoring of warranty claims. When the
failure rate reaches a specified level (the greater of 25 component failures or
one percent of engines built), reports are required to be filed with CARB, and a
recall may be required if the failure rate reaches a higher level (the greater
of 50 component failures or two percent of engines built).
 
LEGAL PROCEEDINGS
 
    The Company is not presently involved in any legal proceedings. In August,
1996, RODI tendered an offer to rescind the investment of its shareholders
(except for officers, directors, their immediate families and certain accredited
individuals investing through private placements). The rescission tender offer
was qualified with the SEC under Regulation A and in most states which required
a filing. The purpose of the offer was to limit or eliminate potential
securities claims that might be asserted against the Company based on possible
violations of state and federal securities laws by reason of non-registration of
shares to persons investing in the Company's stock.
 
    The rescission tender offer was made to 896 shareholders which beneficially
owned approximately 4,977,364 shares of the Company's common stock for which
approximately $2,379,048 had been paid. 104 shareholders elected to rescind
their investment in the Company and were paid an aggregate price of $232,153
including interest as prescribed by state law. The subject $232,153 was paid
from a loan by certain of RODI's directors to the Company. See "Certain
Relationships and Related Transactions

WARRANTIES
 
    The RODI engine warranty which it plans to offer to its customers is
intended to minimize the customer's down time. If in the first 300,000 miles or
6000 hours of service an engine cannot be repaired within 8 hours, the engine
will be replaced at no charge with a time adjusted warranty. If between 300,000
and 400,000 miles or 6000 and 7000 hours of service an engine cannot be repaired
within 8 hours, the engine will be replaced for a charge equal to 70 percent of
the original purchase price. If an engine is traded in on a new engine before it
has accumulated 400,000 miles or 7000 hours, the owner will be granted a 35%
discount off the purchase price. No estimates can be given as to what future
warranty claim levels will be.
 
                             CHANGE IN ACCOUNTANTS
 
    The Company formerly engaged the services of Arthur Andersen LLP
("Accountant") to perform required audits for a 1996 Regulation A securities
filing. The Accountant declined to stand for re-election on August 26, 1996. The
Accountant's report, dated January 17, 1996 was modified as to uncertainty about
the Company's ability to continue as a going concern due to lack of working
capital and the outcome of the Company's Rescission Offer. See "Business--Legal
Proceedings".
 
    There were no disagreements with the Accountant on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure. The Company has authorized the Accountant to respond fully to
inquiries of a successor accountant.
 
    A new accountant, Kenneth E. Walsh, was engaged by the Company on November
1, 1996, and has audited and expressed an opinion on the Company's financial
statements for the Offering.

1992 INCENTIVE STOCK OPTION PLAN
 
    On April 30, 1992 the Company's Board of Directors adopted and a majority of
its shareholders approved, an Incentive Stock Option Plan ("ISOP") for the
benefit of the Company's officers, directors and key employees.
 
    Under the ISOP, options granted are intended to qualify as "incentive stock
options" under Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"). The ISOP authorizes the granting to key employees of options to
purchase an aggregate of 6,000,000 shares of the Company's common stock. Unless
terminated earlier by the Board of Directors, the ISOP will terminate on
November 11, 1997.
 
    The ISOP provides for administration of the plan by the Board of Directors
or by a committee thereof. Subject to the limitations set forth in the ISOP, the
Board has the authority to select the persons to whom grants are to be made, to
designate the number of shares to be covered by each option, to establish
vesting schedules, to specify the type of consideration to be paid to the
Company upon exercise, and to specify certain other terms of the options.
Currently, the full Board of Directors administers the ISOP.
 
    The exercise price of stock options granted under the ISOP must at least
equal the fair market value of the common stock on the date of grant. The
exercise price of incentive stock options granted under the ISOP to stockholders
possessing more than 10% of the total combined voting power of all classes of
stock of the Company must be not less and 110% of the fair market value of the
Company's Common Stock on the date of grant, and such options must not be
exercisable after the expiration of ten years from the date the incentive stock
option is granted.
 
    Options granted under the ISOP must be exercised within ten years from the
date the ISOP is adopted or the date the ISOP is approved by shareholders,
whichever is earlier. Incentive stock options generally are nontransferable and
expire immediately upon termination of any optionee's service with the Company.
However, options granted under the ISOP may be exercised within 12 months after
the date of an optionee's termination of service with the Company by reason of
death or disability, or within three months after the date of termination by
reason of retirement or voluntary termination approved by the Board of
Directors.

the following directors: Byron R. Spain, Donavan E. Garman, Winston D. Bennett,
Gwendolyn S. Spain, David Teo, Marilyn D. Mays, Steven E. Garman and Gary A.
McLean. The notes are dated September 20, 1996 and are payable on the maturity
date, September 20, 1998. See "Business--Legal Proceedings".
 
    On July 15, 1995, the Company and Byron R. Spain entered into that certain
Intellectual Property Assignment and Release Agreement ("Assignment"). Under the
Assignment, Mr. Spain assigned all of his right, title and interest in and to

Power by RODI, A FORMULA FOR SUCCESS, and the pictorial representation of these
trademarks as registered.
 
    On February 19, 1997 and April 23, 1997, Byron R. Spain, Donovan E. Garman
and Steven E. Garman loaned a total of $30,000 and $60,000 respectively to the
Company for working capital. The loans bear interest at the rate of 9% per annum
and are payable 24 months from the respective loan dates.

                            DESCRIPTION OF THE UNITS
 
    Each Unit being offered by the Company consists of one share of Common
Stock, $.01 par value, and one redeemable Common Stock purchase Warrant. Each
purchaser of Units in the Offering will receive separate certificates for the
Warrants and Common Stock upon completion of the Offering and the Common Stock
and Warrant comprising each Unit will be separately transferable upon issuance.
See "Description of Capital Stock" for a description of the Common Stock and the
Warrants.
 
    The basis of the Warrant and the Common Stock purchased by the holder as
part of a Unit or upon exercise of a Warrant will be determined by allocating
the cost of each Unit between the Common Stock and the Warrant in accordance
with the relative fair market values of those elements at the time of
acquisition.
 
    No gain or loss will be recognized by a holder upon the exercise of a
Warrant. The sale of a Warrant by a holder or the redemption of a Warrant by a
holder will result in the recognition of gain or loss in an amount equal to the
difference between the amount realized by the holder and the Warrant's adjusted
basis in the hands of the holder. Provided that the holder is not a dealer in
the Warrants and that the Common Stock would have been a capital asset in the
hands of the holder had the Warrant been exercised, gain or loss from the sale
or redemption of a Warrant will be long-term or short-term capital gain or loss
to
 
                                       39
<PAGE>
the holder. Loss on the expiration of a Warrant, equal to the Warrant's adjusted
basis in the hands of the holder, will be a long-term or short-term capital
loss, depending on whether the Warrant had been held for more than one year.
 
    THE ABOVE DISCUSSION DOES NOT ADDRESS ALL OF THE TAX CONSIDERATIONS THAT MAY
BE RELEVANT TO A PARTICULAR PURCHASER. ACCORDINGLY, ALL PROSPECTIVE PURCHASERS
ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE FEDERAL, STATE,
LOCAL AND FOREIGN TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF
THE WARRANTS AND THE COMMON STOCK.

<PAGE>
                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of (i) 30,000,000
shares of Common Stock, par value $0.01, of which 12,673,085 shares were
outstanding as of May 31, 1997 and (ii) 30,000,000 shares of preferred stock, no
par value, none of which is outstanding.
 
COMMON STOCK
 
    Holders of Common Stock are entitled to one vote for each share held on all
matters submitted to a vote of shareholders. The Articles of Incorporation do
not limit cumulative voting rights. Accordingly all holders of common stock are
entitled to cumulate their shares when voting for directors of the Company.
 
    Upon the liquidation, dissolution or winding up of the Company, the holders
of Common Stock are entitled to receive ratably the net assets of the Company
available after payment of all debts and other liabilities and payment in full
to holders of Preferred Stock then outstanding, if any, of any amount required
to be paid under the terms of such Preferred Stock. The outstanding shares of
Common Stock are, and the shares offered by the Company in this offering will
be, when issued and paid for, validly issued, fully paid and nonassessable. Of
the total authorized shares of Common Stock, 6,000,000 shares have been reserved
for grant under the Company's 1992 Stock Option Plan and 100,000 shares have
been reserved for purchase under the Underwriter Warrants.
 
PREFERRED STOCK
 
    Pursuant to the Company's Articles of Incorporation, the Board of Directors
is authorized to issue from time to time up to 30,000,000 shares of Preferred
Stock, in one or more series, and the Board of Directors is authorized to fix
the dividend rates, any conversion rights or right of exchange, any voting
right, any rights and terms of redemption (including sinking fund provisions),
the redemption price or prices, the liquidation preferences and any other
rights, preferences, privileges and restrictions of any series of Preferred
Stock and the number of shares constituting such series and the designation
thereof. There are no shares of Preferred Stock outstanding.
 
    Depending upon the rights of such Preferred Stock, the issuance of Preferred
Stock could have an adverse effect on holders of Common Stock by delaying or
preventing a change in control of the Company, diluting the voting rights of
holders of Common Stock, making removal of the present management of the Company
more difficult or resulting in restrictions upon the payment of dividends and
other distributions to the holders of Common Stock, including, without
limitation, any liquidation preferences which may relate to such Preferred
Stock.
 
WARRANTS
 
    The following is a brief summary of certain provisions of the Warrants, but
such summary does not purport to be complete and is qualified in all respects by
reference to the actual text of the Warrant Agreement between the Company, and
U.S. Stock Transfer Corporation (the "Warrant Agent"), a copy of which has been
filed as an exhibit to the Registration Statement of which this Prospectus is a
part.
 
    EXERCISE PRICE AND TERMS.  Each Warrant entitles the registered holder
thereof to purchase, at any time commencing          , 1998 [12 months after the
date of this Prospectus], until          , 2002 [5 years after the date of this
Prospectus], one share of Common Stock at a price of $5.00 per share, subject to
adjustment in accordance with the anti-dilution provisions referred to below.
The holder of any Warrant may exercise such Warrant by surrendering the
certificate representing the Warrant to the Warrant Agent, with the subscription
form thereon properly completed and executed, together with payment of the
exercise price. The Warrants may be exercised at any time in whole or in part at
the applicable exercise price until the expiration of the Warrants. No
fractional shares will be issued upon the exercise of the
 
                                       41
<PAGE>
Warrants. The exercise price of the Warrants bears no relationship to any
objective criteria and should in no event be regarded as an indication of any
future market price of the securities offered hereby.
 
    ADJUSTMENTS.  The exercise price and the number of shares of Common Stock
purchasable upon the exercise of the Warrants are subject to adjustment, upon
the occurrence of certain events, including stock dividends, stock splits,
combinations or reclassifications of the Common Stock or for a period of two
years from the date of this Prospectus, the sale by the Company of shares of its
Common Stock or other securities convertible into Common Stock at a price below
the initial public offering price of the Common Stock, excluding shares of
Common Stock issued in connection with incentive or benefit plans of the Company
and strategic alliances. Additionally, an adjustment will be made in the case of
a reclassification or exchange of Common Stock, consolidation or merger of the
Company with or into another corporation (other than a consolidation or merger
in which the Company is the surviving corporation) or sale of all or
substantially all of the assets of the Company, in order to enable
warrantholders to acquire the kind and number of shares of stock or other
securities or property receivable in such event by a holder of the number of
shares of Common Stock that might have been purchased upon the exercise of the
Warrant.
 
    REDEMPTION PROVISIONS.  Commencing            , 1998 [12 months after the
date of this Prospectus], the Warrants are subject to redemption at $.05 per
Warrant on 30 days' prior written notice provided that the average closing sales
price of the Common Stock as reported on the NASDAQ equals or exceeds $7.50 per
share (subject to adjustment for stock dividends, stock splits, combinations or
reclassifications of the Common Stock), for any 20 trading days within a period
of 30 consecutive trading days ending on the fifth trading day prior to the date
of the notice of redemption. In the event the Company exercises the right to
redeem the Warrants, such Warrants will be exercisable until the close of
business on the business day immediately preceding the date for redemption fixed
in such notice. If any Warrant called for redemption is not exercised by such
time, it will cease to be exercisable and the holder will be entitled only to
the redemption price.
 
    TRANSFER, EXCHANGE AND EXERCISE.  The Warrants are in registered form and
may be presented to the Warrant Agent for transfer, exchange or exercise at any
time on or prior to their expiration date five years from the date of this
Prospectus, at which time the Warrants become wholly void and of no value. If a
market for the Warrants develops, the holder may sell the Warrants instead of
exercising them. There can be no assurance, however, that a market for the
Warrants will develop, or if it develops, that it will continue.
 
    WARRANTHOLDERS NOT SHAREHOLDERS.  The Warrants do not confer upon holders
any voting, dividend or other rights as shareholders of the Company.
 
    MODIFICATION OF WARRANTS.  The Company and the Warrant Agent may make such
modifications to the Warrants as they deem necessary and desirable that do not
adversely affect the interests of the warrantholders. The Company may, in its
sole discretion, lower the exercise price of the Warrants for a period of not
less than 30 days on not less than thirty (30) days' prior written notice to the
warrantholders and the Representative. Modification of the number of securities
purchasable upon the exercise of any Warrant, the exercise price and the
expiration date with respect to any Warrant requires the consent of two-thirds
of the warrantholders.
 
    The Warrants are not exercisable unless, at the time of the exercise, the
Company has a current prospectus covering the shares of Common Stock issuable
upon exercise of the Warrants, and such shares have been registered, qualified
or deemed to be exempt under the securities laws of the state of residence of
the exercising holder of the Warrants. Although the Company will use its best
efforts to have all of the shares of Common Stock issuable upon exercise of the
Warrants registered or qualified on or before the exercise date and to maintain
a current prospectus relating thereto until the expiration of the Warrants,
there can be no assurance that it will be able to do so.
 
                                       42
<PAGE>
    The Warrants are separately transferable immediately upon issuance. Although
the Securities will not knowingly be sold to purchasers in jurisdictions in
which the Securities are not registered or otherwise qualified for sale,
purchasers may buy Warrants in the aftermarket or may move to jurisdictions in
which the shares underlying the Warrants are not so registered or qualified
during the period that the Warrants are exercisable. In this event, the Company
would be unable to issue shares to those persons desiring to exercise their
Warrants and holders of Warrants would have no choice but to attempt to sell the
Warrants in a jurisdiction where such sale is permissible or allow them to
expire unexercised.
 
MARKET INFORMATION
 
    Prior to this Offering, there has been no established public trading market
for the Common Stock or the Warrants. The Company anticipates that upon
completion of this Offering, the Common Stock will be listed on the Nasdaq Stock
Market under the symbol "RODI" and the Warrants will be listed under the symbol
"RODIW."
 
TRANSFER AGENT
 
    The transfer agent and registrar for the Common Stock and Warrants is U.S.
Stock Transfer Corporation located at 1745 Gardena Avenue, Glendale, California
91204-2991.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this Offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market could adversely affect prevailing market prices.
 
    Upon completion of this Offering, if the Maximum Amount is raised the
Company will have 17,673,085 shares of Common Stock outstanding (assuming none
of the Warrants are exercised), of which the 5,000,000 shares offered hereby
(and the 5,000,000 shares issuable upon exercise of the Warrants) will be
transferable without restriction under the Securities Act. If the Minimum Amount
is raised, 13,673,085 shares will be outstanding.
 
    The other 12,673,085 outstanding shares of Common Stock are "restricted
securities" (as that term is defined in Rule 144 promulgated under the
Securities Act) which may be publicly sold only if registered under the
Securities Act or if sold in accordance with an applicable exemption from
registration, such as Rule 144. In general, under the revised holding period
requirements of Rule 144, subject to the satisfaction of certain other
conditions, a person, including an affiliate of the Company, who has
beneficially owned restricted securities for at least one year, is entitled to
sell (together with any person with whom such individual is required to
aggregate sales) within any three-month period, a number of shares that does not
exceed the greater of 1% of the total number of outstanding shares of the same
class, or, if the Common Stock is quoted on the Nasdaq Stock Market or another
national securities exchange, the average weekly trading volume during the four
calendar weeks preceding the sale. Sales under Rule 144 are also subject to
certain manner of sale provisions, notice requirements, and the availability of
current public information regarding the Company. A person who has not been an
affiliate of the Company for at least three months, and who has beneficially
owned restricted securities for at least two years, is entitled to sell such
restricted shares under Rule 144(k) ("Rule 144(k) Shares") without regard to any
of the limitations described above.
 
    Options granted under the 1992 Incentive Stock Option Plan to purchase a
total of 4,624,559 shares of Common Stock are currently outstanding, and options
to purchase an additional 1,244,691 shares of Common Stock are reserved for
future issuance under the Stock Plan. Of the options granted under the Stock
Plan, 4,287,559 of such options were currently exercisable as of May 31, 1997,
with the remaining outstanding options to become exercisable at the rate of
171,000 options in 1997, and 166,000 in 1998. Shares of Common Stock issued upon
the exercise of outstanding options will be "restricted securities" and may not
be sold in the absence of registration under the Securities Act unless an
exemption from registration is available. Potential exemptions include those
available under Rule 144.
 
                                       43
<PAGE>
    In addition, the Company intends to register on Form S-8 under the
Securities Act, as soon as possible after the completion of the Offering, shares
of Common Stock issuable under options granted under the Incentive Stock Option
Plan. Such registration becomes effective immediately upon its filing with the
Securities and Exchange Commission.
 
    No prediction can be made as to the effect that future sales of Common
Stock, or the availability of shares of Common Stock for future sale, will have
on the market prices of the Common Stock and Warrants prevailing from time to
time. As of May 31, 1997, 12,673,085 shares of Common Stock outstanding were
owned by 832 holders of record, of which 6,636,134 shares are owned by
"affiliates" and 6,036,951 shares are owned by non-affiliates. Of the 6,036,951
shares owned by non-affiliates, 5,439,289 of these shares would be immediately
eligible for sale upon completion of the Offering, and 4,740,744 of such shares
are Rule 144(k) Shares which may be sold without regard to the volume
limitations of Rule 144.
 
    6,635,978 of the shares of Common Stock owned by affiliates would be
saleable under Rule 144 upon completion of the Offering, subject to the volume
limitations of Rule 144. However, pursuant to the Lock-Up Agreements, all
officers and directors of the Company have agreed not to, directly or
indirectly, agree or offer to sell, transfer, assign, distribute, grant an
option for purchase or sale of, pledge, hypothecate or otherwise encumber or
dispose of any beneficial interest in Common Stock beneficially owned (including
Common Stock acquired upon exercise of Incentive Stock Options) for a period of
      months following the date of this Prospectus without the prior written
consent of the Underwriter. Assuming that the Underwriter does not release the
officers and directors from the Lock-Up Agreements, after the Lock-Up period all
of the shares will be eligible for sale in the public market.
 
    The sale or issuance, or the potential for sale or issuance, of Common Stock
by non-affiliates upon completion of the Offering and by officers and directors
after such       -month lock-up period could have an adverse impact on the
market prices of the Common Stock and/or the Warrants. Sales of substantial
amounts of Common Stock or the perception that such sales could occur could
adversely affect prevailing market prices for the Common Stock and/or the
Warrants. See "Underwriting."
 
    In addition, Rule 144A as currently in effect, in general, permits unlimited
resales of certain restricted securities of any issuer provided that the
purchaser is an institution that owns and invests on a discretionary basis at
least $100 million in securities or is a registered broker-dealer that owns and
invests $10 million in securities. Rule 144A allows the existing stockholders of
the Company to sell their shares of Common Stock to such institutions and
registered broker-dealers without regard to any volume or other restrictions.
Unlike under Rule 144, restricted securities sold under Rule 144A to
non-affiliates do not lose their status as restricted securities.

                                  UNDERWRITING
 
    The Company has entered into an Underwriting Agreement with Intrepid
Securities, Inc. (the "Underwriter"). Pursuant to the terms of the Underwriting
Agreement, the Underwriter has agreed to use its best efforts to sell the Units,
as exclusive agent for the Company.
 
    The Units will be offered for a period of ninety (90) days from the date of
this Prospectus, which period may be extended for an additional ninety (90) days
upon mutual agreement between the Company and the Underwriter (the "Offering
Period"). The Company intends to extend the Offering beyond 90 days if the
Minimum Amount is not raised during the initial 90 days. If the Underwriter is
unable to sell the Minimum Amount of Units within the Offering Period, this
Offering will terminate and all funds will be returned to subscribers in full,
without interest or deduction for commissions or other expenses relating to the
Offering. All funds received by the Underwriter will be transmitted promptly to
an escrow account maintained by U.S. Bank of Washington, pursuant to the terms
of an escrow agreement. Purchasers of the Units will not receive Units unless
and until the funds are released from escrow pursuant to the terms of the escrow
agreement.
 
    Subject to the sale of the Minimum Amount of Units, the Company has agreed
to pay the Underwriter a sales commission of ten percent (10%) of the aggregate
offering price of the Units (the "Underwriter Sales Commission"), and a
nonaccountable expense allowance of three percent (3%) of the gross proceeds of
the Offering. The Company has also agreed to sell to the Underwriter warrants to
purchase the Company's Common Stock in an amount equal to two percent (2%) of
the Common Stock sold by the Underwriter (or participating underwriters or
broker-dealers) in the Offering, which Warrants may be exercised during a four
(4) year period commencing on that date which is twelve (12) months after the
date of this Prospectus.
 
    The Underwriter has the right to engage other broker-dealers which are
members of the National Association of Securities Dealers, Inc. (the
"Participating Dealers") to assist in the offer and sale of the Units, and may
allow such Participating Dealers up to 100% of the Underwriter Sales Commission.
In this regard, the Underwriter will enter into a Participating Dealer Agreement
with each Participating Dealer (a copy of which is filed as an exhibit to the
Registration Statement of which this Prospectus is a part). The Underwriter may
purchase Units for accounts over which it has discretionary authority; however,
at this time the Underwriter has no intention to do so.
 
    In the Underwriting Agreement, the Company has agreed to indemnify the
Underwriter against certain liabilities, including liabilities under the federal
securities laws, or to contribute to payments which the Underwriter may be
required to make in respect thereof.
 
    Prior to the Offering, there has been no public market for the Common Stock
or Warrants. The initial public offering price of the Units has been determined
by negotiation between the Company and the Underwriter. Among the factors
considered in determining the initial public offering price, in addition to
prevailing market and general economic conditions, are the history of the
industry in which the Company principally competes, the historical results of
operations of the Company, the experience of the Company's management, the
Company's earnings prospects and other relevant factors. There can be no
assurance, however, that the price at which the Common Stock or Warrants will
sell in the public market after this Offering will not be lower than the price
at which it is sold by the Underwriter.
 
                                 LEGAL MATTERS
 
    The legality of the Securities offered hereby will be passed upon for the
Company by Prindle, Decker & Amaro, LLP, Long Beach, California. The Law Offices
of Rick Morse, Santa Monica, California has acted as counsel to the Underwriter
in connection with the Offering.

                          INDEPENDENT AUDITORS REPORT
 
To the Board of Directors
 
RODI Power Systems, Inc.
 
    I have audited the accompanying Balance Sheets of RODI Power Systems, Inc.
(a Washington corporation in the development stage) as of December 31, 1996 and
1995 and the related Statements of operations, Stockholders' deficit and Cash
Flows for the period from July 20, 1987 (inception) to December 31, 1995, the
year ended December 31, 1996, and for the period from July 20, 1987 (inception)
through December 31, 1996. These financial statements are the responsibility of
the Company's management. My responsibility is to express an opinion on these
statements based on my audits.
 
    I conducted my audits in accordance with generally accepted auditing
standards. Those standards require that I plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
I believe that my audits provide a reasonable basis for my opinion.
 
    In my opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of RODI Power Systems, Inc. as of
December 31, 1996 and 1995, and the results of their operations and cash flows
for the period from July 20, 1987 (inception) to December 31, 1995, the year
ended December 31, 1996, and for the period from July 20, 1987 (inception)
through December 31, 1996, in conformity with generally accepted accounting
principles.
 
    The accompanying financial statements have been prepared assuming the
Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company is a development stage company, with limited
capital resources, and has incurred accumulated losses of $3,375,345 as of
December 31, 1996. This raises questions about the Company's ability to continue
as a going concern. Management's plan in regard to this matter is described in
Note 2.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  NATURE OF OPERATIONS AND SIGNIFICANT POLICIES:
 
    Rodi Power Systems, Inc. (the Company), a Washington corporation in the
development stage, is engaged in designing and developing a new heavy-duty
diesel engine with potential applications in the trucking industry, as well as
other potential commercial markets.
 
    Since inception, the Company's efforts have been devoted to the development
of its product and raising capital. To date, the Company has not engaged in any
production, manufacturing or sales activities and has an accumulated net loss of
$3,429,421. Accordingly, the Company is in the development stage and the
accompanying financial statements represent those of a development stage
enterprise.
 
    The Company is subject to risks inherent in any new business enterprise.
These risks include, but are not limited to, the Company's limited operating
history and lack of profitability; the need for additional financing to fund
future research and development activities; the need to successfully design,
develop, manufacture and market the Company's product; competition from
established companies with greater resources; and the Company's dependence on
its founder and other key management personnel. There can be no assurance that
the Company will be successful in managing these risks.
 
    On July 20, 1987, the Company incorporated in Delaware as Rotary Diesels,
Incorporated. On October 4, 1991 the Company changed its corporate domicile by
Incorporating in Washington state. The Company's articles of incorporation were
amended on May 24, 1993 to effect a name change to RODI Power Systems, Inc.
 
    CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with a maturity of three
months or less at the date of purchase to be cash equivalents.
 
    PROPERTY AND EQUIPMENT AND DEPRECIATION
 
    Property and equipment are carried at cost. Maintenance, repairs and minor
renewals are expensed as incurred. When assets are retired, or otherwise
disposed of, the related costs and accumulated depreciation are removed from the
respective accounts and any gain or loss on disposition is reflected in the
statement of operations. Depreciation is calculated using the straight-line
method, after effecting a 10% salvage value, over the following estimated useful
lives;

    RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
    In March of 1995, the Financial Accounting Standards Board issued standard
No. 121, "Accounting for the Impairment of Long-Lived Assets and Long-lived
Assets to be disposed of". The Company has adopted standard No. 121 as of
January 1, 1996. The effect on the financial statements of adopting standard No.
121 was not material.
 
    In October 1995, the Financial Accounting Standards Board issued standard
No. 123. "Accounting for Stock-Based Compensation". The accounting or disclosure

the Company's fiscal year-end 1996 financial statements. The Company has adopted
standard No 123 as of January 1, 1996. The effect on the financial statements of
adopting standard No. 123 was not material.
 
    RESEARCH AND DEVELOPMENT
 
    Research and development costs are expensed as incurred.
 
    NET LOSS PER SHARE
 
    Net loss per share is calculated using the weighted average number of shares
outstanding during the periods presented.
 
    ESTIMATES USED IN FINANCIAL STATEMENT PRESENTATION
 
    The presentation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
2.  ABILITY TO CONTINUE AS A GOING CONCERN:
 
    As described in Note 1, the Company is a development stage enterprise. A
marketable version of the Company's diesel engine has not yet been successfully
developed. As of December 31, 1996, the Company has accumulated operating losses
of $3,429,421 and has limited capital resources. Future research and development
activities are necessary and are dependent upon the Company's ability to raise
additional capital. These factors raise doubt about the Company's ability to
continue as a going concern. Management's plans in this reguard are to raise
additional capital in 1997 by offering additional shares of the Company's common
stock under Regulation SB-2 of the Securities Act of 1993. There can be no
assurance that the Company will be successful in raising additional capital in a
public offering of its stock. In addition, until the public offering becomes
Qualified management is actively seeking to raise additional capital in isolated
private sales of the Company's stock to accredited investors. Management
believes that there is adequate investor interest to continue to fund the
Company's operations in the foreseeable future.
 
3.  RESCISSION OFFER:
 
    The Company has sold common stock to investors without registering the
securities for sale with the appropriate federal and state regulatory agencies
and was in violation of federal and state security laws. To limit the potential
liability from the sale of these unregistered securities, the Company issued a
Rescission Offer to Certain Stockholders, whereby the Company offered to refund
certain stockholder investments in the Company, plus interest from the date of
investment, in return for shares of the Company's common stock. As of December
31, 1996 250,040 shares of stock have been rescinded by the stock holders. This
rescission money was paid for by a loan from eight different members of the
Board of Directors of the corporation. The Rescission offer date had expired as
of December 31, 1996 and no future contingent liabilities exist as a result of
the rescission.

4.  INCOME TAXES:
 
    Deferred taxes relate to differences between the basis of assets and
liabilities for financial and tax reporting purposes. Deferred tax assets and
liabilities represent the future tax consequences of those differences, which
will either be taxable or deductible when the assets and liabilities are
recovered or settled. Deferred taxes also are recognized for net operating
losses that are available to offset future taxable income. Deferred tax assets
are reduced by a valuation allowance if it is more likely than not that some or
all of the deferred tax assets will not be realized.
 
    At December 31, 1995 and 1996, the Company had net operating loss
carryforwards totaling approximately $2,608,000 and $3,429,421, respectively,
that may be offset against future taxable income. The Company's net operating
losses begin to expire in the year 2003. Details regarding the Company's
deferred taxes are presented below:

                              TECHNICAL ASSESSMENT
                               RODI DIESEL ENGINE
 
    This is a brief report of the technical assessment of the Rodi HT1-450 Turbo
Diesel Engine submitted 13 January 1997.
 
I.  INTRODUCTION
 
    The Rodi HT1-450 Diesel Engine is a four cylinder vee two-cycle engine
designed for application in a heavy duty highway truck. This engine utilizes two
unique enabling technologies; a reverse uniflow two-stroke scavenging cycle and
a two point microprocessor fuel system control and its associated software.
 
    The reverse uniflow scavenging feature is unique since it is a departure
from current production two-cycle engine design which have air inlet ports at
the bottom of the cylinder and exhaust valves in the cylinder head.
 
    In the reverse uniflow two-stroke cycle, pressurized air is admitted via
intake valves located in the cylinder head and exhaust is discharged through
ports machined into the lower extremity of each cylinder liner. This eliminates
the requirement for exhaust valves while achieving efficient scavenging of the
exhaust gases within the cylinders. The pressurized scavenging air is supplied
by a positive displacement supercharger directly connected to the crankshaft.
 
    The two point microprocessor engine control permits initiation and
termination of fuel delivery to be programmed independently. This system also
monitors and controls all engine functions to optimize operating efficiency.
 
    A mechanically driven unit fuel injector is utilized to produce high
injection pressures (up to 25,000 pounds per square inch) for improved
combustion efficiency and emissions.
 
    The V-4 with 90 degree banks provides a compact short overall length and
light weight engine for improved truck application. The two cycle firing
sequence gives the same cyclic torque impulse as an eight cylinder V-8 four
cycle engine. This eliminates transmission and drive line problems from cyclic
torque variations.
 
    The benefits of a V-4 over an in line 6 configuration include reducing the
number of main bearings from 7 to 3 and reducing the length of the crankshaft by
45%. There is a proportional reduction in components throughout the engine
resulting in 40% fewer components and hence significantly lowering the cost of
production. A major difference between four-stroke engines and reverse uniflow
two-stroke engines is the absence of exhaust valves and exhaust heated passages
in the cylinder head. This results in a significant reduction in exhaust heat
loss to the coolant and greatly improves head and valve life. Most of the heat
normally lost to the coolant is harnessed by two turbochargers which increases
the amount of combustion air available. By using individual turbochargers on
each bank of the V engine, either half of the engine can be operated independent
of the other; allowing two cylinder operation during periods of idling or light
loading.
 
    The selection of the two-cycle diesel combustion process for application in
a highway truck deserves some serious consideration. The four-cycle diesel
combustion process has been predominately utilized for on-highway truck engine
applications except for truck engines produced by Detroit Diesel Corporation.
 
    The difference between these cycles has the following effect on the basic
engine components and engine performance. In the two-cycle engine, the
combustion and power stroke occurs every revolution of the crankshaft. In the
four-cycle engine, combustion and power strokes occur on alternate revolutions
of the crankshaft. The two-cycle engine fires every revolution so theoretically
the same power could be
 
                                      A-1
<PAGE>
produced with half the displacement of a four-cycle engine. This cannot be
achieved in actual practice for the follow reasons:
 
        1.  The two-cycle engine has only a few crank angle degrees at the
    bottom of its stroke to complete its exhaust blow-down, scavenging and
    recharge of intake air as compared to a complete revolution of the
    four-cycle engine for this process.
 
        2.  The hot components in the two-cycle engine are subjected to high
    temperature and pressure every revolution as compared to every other
    revolution in the four-cycle engine. The four-cycle engine components can
    rest and be cooled with inlet air in the idle scavenge and intake cycles.
 
        3.  The short crank angle time in the two-cycle for scavenging exhaust
    gases and recharging with fresh air results in problems in controlling
    exhaust emissions (smoke, unburned hydrocarbons and Nitrous Oxides). The
    exhaust emission problem in the four-cycle engine is easier to control since
    the cylinder is completely purged in the extra cylinder strokes for exhaust
    and intake of air. The two-cycle engine does however, typically operate at
    lower combustion temperatures which tends to reduce the formation of Nitrous
    Oxides.
 
        4.  The two-cycle engine requires the use of an external source of low
    pressure air such as a roots blower to aid in the scavenging process. This
    creates an additional source of accessory power loss and contribution to the
    exhaust emission problem.
 
    In consideration of the above factors, the two-cycle engine in practice is
limited to approximately one half the BMEP (Brake Mean Effective Pressure) of
the four-cycle engine in high specific power supercharged engines.
 
II.  REVERSE UNIFLOW SCAVENGING
 
    The unique feature of the Rodi HT1-450 engine is the design of a two-cycle
engine using the concept of reverse uniflow scavenging for the flow of gases
through the cylinder. Air is admitted to the cylinder through an intake valve
system in the cylinder head and exhausted through ports at the bottom of the
cylinder.
 
    The reverse uniflow scavenge concept has the potential for basic
improvements in engine efficiency and packaging, but also has inherent problems.
 
    Advantages:
 
        1.  The cylinder head design can be simplified with the elimination of
    the hot exhaust gases. Cooling can be either eliminated or greatly
    simplified. Complex cored passages and gasket sealing problems are thus
    eliminated. A simple single cylinder head with lower profile for reduced
    engine bulk and weight becomes possible.
 
        2.  Vee engines have problems with overall width in highway vehicles.
    The more compact cylinder head will be very favorable with this design.
 
        3.  Valve and valve seat life will be improved from cooling effects of
    inlet air.
 
        4.  The ports at the bottom of the cylinder will provide increased area
    for less exhaust flow restriction and a better blow-down feature through
    rapid rate of area opening. This should result in efficient gas flow and
    improved scavenging and better fuel consumption.
 
                                      A-2
<PAGE>
    Disadvantages:
 
        1.  The high temperature components of the cylinder are buried in the
    cylinder block. This will create problems with the design of the cooling
    system and its seals. This will also create problems with the design for
    access to the hot elements and seals for maintenance and repair. RODI's
    proposed use of Min-K super insulation may mitigate this problem.
 
        2.  There will be new problems with the heat concentrated at the lower
    end of the cylinder liner and piston.
 
    A new piston, piston ring set and cylinder liner combination will need to be
developed. Extra cooling to the underside of the piston with cooling jets will
be required. Thermal distortion within the cylinder block structure and lower
end of the liner will be a problem. It may be necessary to cool the liner in the
exhaust port area.
 
III.  TECHNICAL ASSESSMENT OF THE GENERAL PROGRAM
 
    The design of the Rodi HT1-450 engine adheres to sound engineering
principals and thus has the potential to be a successful competitor in the heavy
duty highway truck market.
 
    The general arrangement of the Series III preproduction engine is
substantially improved over the Series I and Series II prototype engine designs.
 
    A completely new mechanical design of the engine hardware is proposed to
bring it up to production standards for good foundry and machine shop practice
and present day tooling.
 
    The 90 degree V-4 arrangement could present installation problems in
existing on-highway trucks because of its width in this horsepower range. A
four-cylinder in-line engine might be more compatible. The present design was
selected to produce a short overall length and light weight package. A new truck
could easily be designed to accept the V-block design.
 
    The use of synthetic lube oil (polyalphaolefin) as coolant should be
reviewed. The concept eliminates one fluid (water) which can be a problem should
an internal seal fail and in cold climates with anti-freeze maintenance. The
specific heat transfer of oil is about one half that of water. This creates the
need for higher coolant flow, radiator sizing and related costs. There is also a
risk to the engine's lubricated elements from coolant loss through leaks in
external plumbing.
 
    It is suggested that the coolant system be designed to use either oil or
water in the development stage to reduce the number of unknowns at this stage.
 
    The use of the lube oil pump as a retarder will be of limited functional
benefit because of the problem of heat rejection. The power absorbed in the
retarder mode turns to heat in the lube oil. This can only be rejected in the
engine coolant radiator which has limits in total rejection.
 
    The power head feature where the cylinder block and head assembly can be
separated from the accessory drive and flywheel assembly without disturbing the
accessories' plumbing or wiring and replaced with a new or remanufactured power
head will result in substantial savings in truck down time and cost.
 
IV.  TECHNICAL ASSESSMENT OF ENGINE COMPONENTS
 
    The cylinder block is well designed for present day tooling. Some effort to
improve internal cooling should be considered. High strength cast iron is the
preferred material.
 
    The design of the piston and cylinder liner is considered consistent with
good production practice. Since the exhaust outlet is at the bottom of the
cylinder, this area will operate at higher temperatures. It will require some
development of piston cooling and piston ring details. Some consideration for
cooling the liner in the exhaust port area may be required.
 
                                      A-3
<PAGE>
    The upper connecting rod and piston pin bushing will operate at higher
temperatures. They may require additional development. The piston pin and upper
end of the connecting rod appear to be complex and may be expensive in
production. Other designs should be considered. The retainer screws do not seem
adequate to hold the piston pin in the event of a scuffed piston skirt.
 
    The new cylinder head with four intake valves per cylinder is an improvement
over the Series I design.
 
    The cylinder head is taller than necessary. The coring and flange connection
for air inlet should be reviewed. The flanges for cylinder head cover are too
thin.
 
    The valve train (cam follower, push rods, rocker arms and bridges) does not
appear adequate in proportion as compared to other heavy duty engines.
 
    The exhaust collector design is improved over the Series I design. It may be
necessary to provide cooling to this component for high power outputs.
 
    The accessory layout and drive arrangement are good.
 
    The crankshaft is considered to be consistent with good design practice. It
is suggested that the material be changed to a steel forging for durability.
 
    The mounting of the heat exchangers to the engine is a good feature. This
can reduce problems of plumbing leaks and potential for engine failure.
 
V.  CONCLUSIONS AND RECOMMENDATIONS
 
    The Rodi HT1-450 turbo diesel engine should easily produce up to 450
horsepower at 1800 revolutions per minute with good fuel economy and durability.
 
    The advantages of the reverse uniflow two-cycle scavenge concept in the V-4
configuration should produce a very attractive and competitive engine for the
heavy duty highway truck market.
 
    The planned production type redesign program will overcome the present
development problems.
 
    The engine is conservatively designed in terms of displacement, average
piston speed and Brake Mean Effective Pressure at the 450 horsepower rating so
there should be adequate reserve for future power growth.
 
    The use of the removable power head will be unique to this engine and will
give it a great competitive advantage.
 
    The use of the unit injectors in combination with the two point
microprocessor fuel control will result in a wide range of flexibility for power
and economy settings along with improved exhaust emissions.

ITEM 28.  UNDERTAKINGS
 
    (1) The undersigned Registrant hereby undertakes that it will:
 
        (a) File, during any period in which offers or sales are being made, a
    post-effective amendment to this registration statement to:
 
            (i) Include any prospectus required by Section 10(a)(3) of the
       Securities Act,
 
                                      II-2
<PAGE>
            (ii) Reflect in the prospectus any facts or events which,
       individually or together, represent a fundamental change in the
       information in the registration statement, and
 
           (iii) Include any additional or changed material information on the
       plan of distribution.
 
        (b) For determining liability under the Securities Act, treat each
    post-effective amendment as a new registration statement of the securities
    offered, and the offering of the securities at that time to be the initial
    bona fide offering.
 
        (c) File a post-effective amendment to remove from registration any of
    the securities that remain unsold at the end of this offering.
 
    (2) The undersigned Registrant hereby undertakes to provide to the
Underwriter at the closing specified in the Underwriting Agreement certificates
in such denominations and registered in such names as required by the
Underwriter to permit prompt delivery to each purchaser.
 
    (3) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of each issue.
 
    (4) The undersigned Registrant hereby undertakes that it will:
 
        (a) For determining any liability under the Securities Act, treat the
    information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4), or
    497(h) under the Securities Act as part of this registration statement as of
    the time it was declared effective.
 
        (b) For determining any liability under the Securities Act, treat each
    post-effective amendment that contains a form of prospectus as a new
    registration statement for the securities offered in the registration
    statement, and the offering of such securities at that time as the initial
    bona fide offering of those securities.

                                        STOCK


Sec. 1.  ISSUANCE.  Shares of stock may be issued in accordance with the
         Articles of Incorporation on such terms and conditions as may be
         determined by the board of directors.  The form of stock certificates
         shall be signed by the chairman of the board of directors, or by the
         president or by the executive vice president, and by the treasurer or
         an assistant treasurer, or by the secretary or an assistant secretary
         and, if the corporation chooses to have a seal, shall be sealed with
         the corporate seal.

Sec. 2   METHOD OF TRANSFER.  Transfers of stock shall be made only on the
         books of the corporation, and the old certificate properly endorsed
         shall be surrendered and canceled before a new certificate is issued.
         All surrendered certificates shall be marked "canceled" with the date
         of cancellation by the secretary and shall be immediately affixed to
         the stock books opposite the memorandum of their issue.

Sec. 3.  LIMITATIONS ON TRANSFERS.  No stockholder may transfer his common
         stock to any person not already a stockholder of the corporation
         without first giving notice to the corporation and to the existing
         stockholders of his intention to do so and of the terms and
         consideration for the same.  Such notice may be by actual written
         notice to each stockholder or by posting the same in a conspicuous
         place in the registered office of the corporation.  For fifteen (15)
         days thereafter, the corporation, acting through its board of
         directors, shall have the prior right to buy the said stock on the
         said terms.  If such preferential right is not exercised within said
         time, then during the next fifteen (15) days any stockholder or
         stockholders may exercise such preferential rights.  Whenever such
         preferential rights are exercised by more than one stockholder without
         an agreement between them as to the proportion to their already
         existing stockholders.  If, at the end of thirty (30) days, no
         stockholder or stockholders have exercised such preferential rights,
         then the stock may be transferred to any person whatsoever on the said
         terms; provided, however, if the corporation is taxed under Subchapter
         S of the Internal Revenue Code of 1986, as amended, no such transfer
         shall be made to any transferee whose ownership would void or endanger
         the corporation's corporation election, unless such transfer is
         permitted by the prior written consent of persons owning a majority of
         the outstanding shares of the corporation.  Notwithstanding anything
         to the contrary herein provided in this section, the transfer of
         shares of a stockholder in the corporation may be made subject to such
         additional or lesser restrictions as may be imposed by written
         agreement by and between the registered owners of such stock and the
         corporation.  Upon the execution of any such agreement, all
         certificates of stock of the corporation shall have endorsed upon them
         appropriate language referring to such agreement and

<PAGE>

         a copy of such agreement shall be filed in the office of the secretary
         of the corporation.

                                STOCKHOLDERS' MEETINGS

Sec. 4.  ANNUAL MEETING.  The annual meeting of the stockholders of this
         corporation shall be held on the 2ND SATURDAY in APRIL of each year,
         commencing with the year 1992, at which time there shall be chosen a
         board of directors consisting of two (2) or more members as shall be
         determined by the stockholders; provided, however, that such number
         shall not exceed eight (8), who need not be stockholders of this
         corporation, and who shall serve as directors of this corporation
         during the ensuing year and until their successors are elected and
         qualify or until their earlier resignation or removal.  A notice of
         such meeting, either written or printed, shall be mailed not less than
         ten (10) or nor more than sixty (60) days before such meeting to each
         voting stockholder to his post office address appearing upon the
         records of the corporation, but the notice shall state the hour and
         the place where the meeting will be held.

Sec. 5.  DEFERRED ANNUAL MEETING.  If, for any reason, the annual meeting of
         the stockholders  shall not be held on the date designated therefor,
         the board of directors shall cause the meeting to be held as soon
         thereafter as convenient.

Sec. 6   SPECIAL MEETINGS.  Special meetings of the stockholders of this
         corporation may be called at any time by the chief executive officer,
         the president, or the board of directors.  It shall also be the duty
         of the chief executive officer, the president or secretary to call a
         special meeting of the stockholders whenever requested to do so by the
         stockholders owning twenty percent (20%) of the entire voting capital
         stock.  If the chief executive officer or secretary on such request
         neglects for two (2) days to call a special meeting as requested, then
         said stockholders making the request may call a special meeting.  Ten
         (10) days' written notice of special meetings shall be given by
         mailing a written or printed notice thereof to each stockholder to his
         post office address appearing on the records of the corporation.  Such
         special meetings need not be held at the registered office of the
         corporation, except any special meeting that is called by the
         stockholders after a demand for the same has been neglected as above
         set forth.  The notice of such special meetings in addition to stating
         the time at which the said meeting shall be held, shall briefly state
         the object of the meeting.

Sec. 7   QUORUM.  The holders of a majority of the issued and outstanding
         shares of the capital stock of the corporation having voting power,
         present in person or by proxy, shall constitute a quorum for the
         transaction of business at any meeting of stockholders except as may
         be otherwise provided by law, the Articles of Incorporation, or the
         Bylaws of this corporation; but if there be less than a quorum, the
         holders of a majority of the stock so present may adjourn the


                                         -2-

         meeting from time to time.  A majority vote of such quorum shall be
         necessary for the transaction of any business.

Sec. 8.  CUMULATIVE VOTING.  At all elections of directors of the corporation,
         each stockholder shall be entitled to as many votes as shall equal the
         number of votes which, except for this provision as to cumulative
         voting, such stockholder would be entitled to cast for the election of
         directors with respect to such stockholder's shares of stock
         multiplied by the number of directors to be elected by each
         stockholder, and each stockholder may cast all of such votes for a
         single director or may distribute them among the number to be voted
         for, or for any two or more of them as such stockholder may see fit.

Sec. 9.  PRESIDING OFFICERS.  All meetings of the stockholders shall be
         presided over by the chief executive officer, and at all such meetings
         the chief executive officer may vote.  In the absence of the chief
         executive officer, the president shall preside and shall have all the
         powers herein conferred upon the chief executive officer when acting
         as the presiding officer.  In the absence of the chief executive
         officer and president, the stockholders may appoint any stockholder to
         act as chairman of the meeting.

Sec. 10. ORDER OF BUSINESS.  At all meetings of the stockholders, the following

         corporation's Articles of Incorporation.  Each director shall receive
         such compensation for his services as shall be decided from time to

         directors unless a greater number is required by the Articles of
         Incorporation or Bylaws of the corporation.

         cause, upon the affirmative vote of the holders of a majority of the
         stock of the corporation having voting power, except as may be
         otherwise provided by law.  In case one or more vacancies by death,

         between the time of the annual meetings, the remaining director or
         directors shall fill the vacancy or vacancies, and the person or
         persons so chosen shall be directors and hold office until their
         successors are elected and qualify.  In case the entire board of
         directors shall die, resign, or be removed, then a special meeting of
         the stockholders may be called, as hereinbefore provide, for the
         election of directors.

Sec. 15. REGULAR MEETINGS.  A regular meeting of the board of directors shall

         address appearing in the records of the corporation not less than

         the powers herein conferred upon the chairman of the board when acting
         as presiding officer.  In the absence of the chairman of the board and
         the president, the board of directors may appoint any director to act

    to establish prices which shall be not less than the fair market value per
    share of Rodi Common Stock which is the subject of the option at the time
    the option is granted.

         5.2  TERM AND MATURITY:  The term of each option shall be established
    by the Board and shall not exceed 10 (ten) years from the date it is
    grated.

    schedule established by the Board, each option may be exercised in whole or
    in part; provided that no fewer than 1000 shares (or the remaining shares

    exercised, together with the exercise price, for the Common Stock being
    purchased.

         5.4  NON-TRANSFERABILITY OF OPTION:  Options granted under the Plan,

    associated with the company by voluntary termination or dismissal for
    cause, for any reason other than death or total disability, during the
    optionee's contract period, the option shall terminate immediately and all
    unexercised option shares shall be forfeited 90 (ninety) days following the
    effective date of termination.  All shares not already exercised may, at
    the discretion of the Board, be offered to other optionees.

         5.6  DEATH OR DISABILITY:  If an optionee dies or becomes totally
    disabled while they are employed in good standing with RODI, their option
    will continue with the person(s) to whom the optionee's rights pass or by
    the applicable laws of descent and distribution.

    6.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION:  The aggregate number of
    shares covered by each outstanding option shall be proportionately adjusted
    for any increase or decrease in the number of issued and outstanding shares
    of Common Stock of RODI resulting from a split or consolidation of shares
    or any like capital adjustment.

    7.  AMENDMENT AND TERMINATION:  The Board may at any time suspend, amend or
    terminate the 1992 Incentive Stock Option Plan.  Unless sooner terminated,
    the 1992 Plan shall terminate 5 (five) years from the date the Plan is
    adopted.

    Systems, Inc. of record on that date.

    invitees.

    In the event the Premises or the Building of which the Premises are a part
    is destroyed or injured by fire, earthquake or other casualty to the extent
    that either is untenable in whole or in part, then Lessor may, at its

    Premises or such part thereof as may be damaged, provided that within
    thirty (30) days after such destruction or injury, Lessor shall notify
    Lessee in writing of its intentions to do so, and provided further that
    Lessor can complete such rebuilding and restoration in one hundred twenty
    (120) days, and during the period of such rebuilding and restoration, the
    rent hereunder shall be abated.  If Lessor shall fail to notify Lessee, as
    aforesaid, then this Lease, at the expiration at the time for giving said
    notice as provided for herein, shall be terminated as of the time of the
    injury or destruction.

<PAGE>

    Lessee will, at all times, keep the Premises neat, clean and in a sanitary
    condition.  Lessor, at its sole expense, shall repair the roof structure,
    walls and foundation of the demised Premises, unless Lessee is responsible
    for such damage, and provided however that Lessee shall be required to
    notify Lessor in the event any repairs which are the Lessor's
    responsibility are necessitated.  All other repairs to Lessee's Premises
    shall be at Lessee's sole cost and expense.  Lessor agrees to repair and
    maintain the common area, parking area and landscaping of the entire
    building on the Property described in Exhibit "A", Lessee agrees to be
    responsible to pay such common expenses incurred by Lessor, which includes
    all Common Areas.  Except for reasonable wear and tear and damage by fire,
    windstorm and Acts of God, or other similar casualty, Lessee will at all
    times preserve said Premises in as good repair as they now are or may
    hereafter be put to.  Lessee agrees that at the expiration or sooner
    termination of this Lease, Lessee will quit and surrender said Premises
    without notice and in a neat and clean condition and will deliver up all
    keys belonging to said Premises to the Lessor or Lessor's agent.  Lessee

    enter any and all portions of the Premises at any and all reasonable times
    with reasonable notice to make such repairs as shall be necessary for the
    safety and preservation of the Premises.  Nothing herein shall imply any
    duty by Lessor to make any such repairs or do any other work that under any
    provision of this Lease, Lessee is required to perform, and the performance
    hereof by Lessor shall not constitute a waiver of Lessee's default, nor
    shall the obligation of Lessee under this Lease be thereby affected in any
    manner.  Furthermore Lessor during the progress of such repairs or other
    work may keep and store on the demised Premises all necessary material,
    tools and equipment, and Lessor shall in no event be liable for
    disturbance, inconvenience, annoyance, loss of business or other damage to

    account of bringing materials, supplies and equipment into or through the
    Premises during the course of such work.  Lessor shall use his best efforts
    to minimize the inconvenience to Lessee, and to perform necessary repairs
    in a timely manner.

    this Lease or any part thereof and shall not let or sublet the whole or any
    portion of the Premises without the written consent of Lessor or Lessor's
    agent.  This Lease shall not be assignable by operation of law.  If consent
    is once given by the Lessor to the assignment of this Lease, or any
    interest therein, Lessor shall not be barred from afterwards refusing to
    consent to any further assignment.  In no event shall Lessor's consent be
    unreasonably withheld.

18.  SUBLETTING

    If Lessee is unable to use the Premises for the purpose herein stated, or
    if he finds the Premises inadequate for his expanded business needs, the
    Lessee will so advise the Lessor in writing and if both agree, the Lease
    may be canceled or the Lessee will be permitted to sublet the space to a
    qualified user, subject to the approval of the mortgage lender and Lessor,
    whose approval shall not be unreasonably withheld.  Until such time as the
    Lessee is able to find a new tenant, the rent and all other obligations or
    the Lessee will continue.  If the Lessee sublets the Premises to a
    qualified user with the approval of Lessor and mortgage lender, and if the
    lease payments from the sublessee to subLessor exceed the rental payments
    payable to Lessor hereunder, then in such event, the rental payable to
    Lessor hereunder shall increase by such amount.  If additional rent is
    received over and above monthly rent for comparable space as a direct
    result from improvements paid for by Lessee, Lessee shall be entitled to
    such additional rent during the original term of this Lease, excluding any
    renewal options.

19.  HAZARDOUS MATERIALS

    (a)  Lessee is in the business of handling materials in manufacturing.
    Lessee has no present intent to use or locate any Hazardous Materials on
    the Premises.  Lessee shall hold Lessor harmless during the term of the
    Lease and thereafter from any and all lawsuits, claims or demands made by
    third parties, including governmental agencies, arising out of or connected
    with Lessee's use or handling of such Hazardous Materials which causes an
    unauthorized storage or contamination of the Premises, including but not
    limited to the presence, escape, seepage, spillage, discharge, emission or
    release on or under the Premises of any Hazardous Material.  This hold
    harmless provision shall have the broadest legal interpretation possible,
    and includes the


                                          9
<PAGE>

    payment of all Lessor's legal fees incurred in any action, demand or claim
    made by a third party for damages or for removal of such substances.  If
    Lessor has reason to believe that Lessee is in breach of this subparagraph
    during the term of the Lease, or after its termination, Lessor may at
    reasonable times upon reasonable notice to Lessee enter the Premises to
    conduct soil tests or an environmental audit.  If the tests or audit reveal
    a breach of this subparagraph, in addition to all of the remedies contained
    herein, Lessee shall be responsible to pay for the cost of such tests or
    audit.

    (b)  To the best of Lessor's knowledge:

         1.   Neither Lessor nor any other person or entity has ever caused or
              permitted any Hazardous Material to be placed, held, located or
              disposed on, under or at the Premises, and the Premises has never
              been used as a dump site, permanent or temporary storage site, or
              transfer station for, and does not contain, any Hazardous
              Material.

         2.   The current conditions of the Premises complies with all laws,
              regulations and decisions of any kind regarding Hazardous
              Material.

         3.   There are no pending proceedings, and no condition exists that,
              with the passage of time, could give rise to any future liability
              to Lessee as a result of the present or past existence of any
              Hazardous Material on the Premises.

    These representations shall survive the voluntary or involuntary transfer
    of the Premises by Lessor and shall survive the termination of this Lease.
    Lessor acknowledges that Lessee has materially relied upon these
    representations in entering into this Lease.

    Lessor shall hold Lessee harmless during the term of the Lease and
    thereafter from any and all lawsuits, claims or demands made by third
    parties through the fault or willful neglect of Lessor, including
    governmental agencies, arising out of or connected with the presence,
    escape, seepage, leakage, spillage, discharge, emission or release on or
    under the Premises of any Hazardous Material, other than such caused by
    Lessee.  This hold harmless provision includes the payment of all Lessee's
    legal fees incurred in any action, demand or claim made by a third party
    for damages or for removal of such substances other than those excepted
    herein.  If Lessee has reason to believe that Lessor is in


                                          10
<PAGE>

    breach of this subparagraph during the terms of the Lease or after its
    termination, Lessee may conduct soil tests or an environmental audit on the
    Premises.  If the tests or audit reveal a breach of this subparagraph,
    Lessee may terminate this Lease, and in addition to all remedies contained
    herein, Lessor shall be responsible to pay for the costs of such tests or
    audit.  Lessor's responsibility hereunder shall be limited to the condition
    of the soils created by Lessor, its predecessors, its agents or past
    Lessee's of the Premises.

    understanding and agreement that Lessee will remove same at the termination
    of the tenancy herein created and repair any damage or injury to the
    Premises caused thereby, ad if not so removed by Lessee, then Lessor may
    have same so removed at Lessee's expense.

    unpaid ten (10) days after written default notice to Lessee, or if Lessee
    shall fail to cure a default in any of the covenants and agreements herein
    contained 30 days after written notice, or if the default is such that it
    may not be cured within 30 days, if Lessee fails to commence to cure within
    30 days and thereafter diligently prosecutes the cure to completion, then
    the Lessor may cancel this Lease in its entirety including but not limited
    to all options, upon giving notice required by law, and re-enter said
    Premises, but not withstanding such re-entry by Lessor, the liability of
    the Lessee for the rent and other obligations provided herein shall not be
    extinguished for the balance of the term of the Lease, and Lessee covenants
    and agrees to make good to Lessor any deficiency arising from a re-entry
    and reletting of the Premises at a lesser rental than therein agreed to.
    The Lessee shall pay such deficiency each month as the amount is
    ascertained by Lessor.  In the event Lessor re-enters the Premises, the

    (ordinary wear and tear excepted).

25. EMINENT DOMAIN


                                          12
<PAGE>

    (a)  Total Condemnation - If the whole of the Leased Premises shall be
    acquired or condemned by eminent domain for any public or quasi-public use
    or purpose, then the term of this Lease shall cease and terminate as of the
    date title or possession shall be transferred to such proceeding, whichever
    shall first occur, and all rentals shall be paid up to that date and Lessee
    shall have no claim against Lessor for the value of any unexpired term of
    this Lease.

    (b)  Partial Condemnation - If any part of the Leased Premises or the
    building in which the Leased Premises are situated shall be acquired or
    condemned by eminent domain for any public or quasi-public use or purpose
    and in the event that such partial taking or condemnation shall render the
    Leased Premises unsuitable for the business of the Lessee, then the term of
    this Lease shall cease and terminate as of the date title or possession
    shall be transferred in such proceeding, whichever shall first occur, and
    Lessee shall have no claim against Lessor for the value of any unexpired
    term of this Lease.  In the event of a partial taking or condemnation which
    is less than twenty percent (20%) of the premises and not extensive enough
    to render the Premises unsuitable for the business of the Lessee, then
    Lessor shall promptly restore the Leased Premises to a condition comparable
    to its condition at the time of such condemnation, less the portion lost
    and rental adjusted accordingly in the taking, and this Lease shall
    continue in full force and effect.  If the parties are unable to agree on
    the issue of the suitability of the remaining portion of the Premises, the
    same shall be submitted to binding arbitration during which period the
    Lease shall remain in effect except that the rental shall be partially
    abated as herein set forth.  Initially the parties shall attempt to agree
    upon one arbitrator..  Any arbitrator selected under this paragraph must be
    a commercial Realtor doing business in King County Washington.  If the
    parties are unable to agree upon one arbitrator within fourteen (14) days,
    each party shall name one arbitrator and the two so selected arbitrators
    shall select a third arbitrator.  If the two arbitrators fail to name a
    third arbitrator within a reasonable period of time, the third arbitrator
    shall be selected by the Presiding Judge of the Superior Court of the State
    of Washington for King County at the request of either Lessor or Lessee.
    The costs of arbitration shall be borne equally between the parties and the
    determination by the arbitrator shall be binding upon the parties and not
    subject to further legal proceedings.

    (c)  Lessor's Damages- In the event of any condemnation or taking as
    hereinbefore provided, whether whole or partial,


                                          13
<PAGE>

    the Lessee shall not be entitled to any part of the award, as damages or
    otherwise, for such condemnation, and Lessor is to receive the full amount
    of such award, the Lessee hereby expressly waiving an right of claim to any
    part thereof.

    (d)  Lessee's Damages - Although all damages in the event of any
    condemnation are to belong to the Lessor, whether such damages are awarded
    as compensation or diminution of value of the Leasehold or the fee, Lessee
    shall have the right to claim and recover such compensation as may be
    separately awarded or recoverable by Lessee in Lessee's own right on
    account of any condemnation for or on account of any cause or loss to which
    Lessee might be put in removing Lessee's inventory, Leasehold improvements
    or equipment.

26. WAIVER OF SUBROGATION

    Lessor hereby reLeases Lessee of and from every and all right, claim and
    demand that Lessor may hereafter have against Lessee, or Lessee's

    losses occasioned by fire and such perils as are included under the normal
    extended coverage clauses of fire insurance policies, and sustained by
    Lessor in or around the Premises.  Lessee hereby releases Lessor from any
    and every right, claim and demand that Lessee may hereafter or in
    connection with any loss or losses occasioned by fire and such perils as
    are included in the normal extended coverage clauses of fire insurance
    policies, and does hereby waive all rights of subrogation in favor of
    insurance carriers against Lessor arising out of any losses occassioned by
    fire, and such perils as are included under the normal extended coverage
    clauses of fire insurance policies, and sustained by Lessee to its trade
    fixtures, equipment and inventory.

    hereby subordinated to all present and future mortgages, deeds of trust and
    other encumbrances affecting the demised Premises or the property of which
    the demised Premises are a part; provided however, that the mortgagee's
    beneficiaries or encumbrance holders shall agree to recognize the term of
    this Lease and not to disturb the


                                          14
<PAGE>

    tenancy created hereby.  The Lessee agrees to execute, at no expense to the

    terminated as provided by the laws of the State of Washington.  During such
    tenancy, Lessee agrees to pay to the Lessor one and one-half (1 1/2) times

    stating whether to the best knowledge of Lessee, there is any default under
    the terms and conditions of the Lease, and if so, specifying each such
    defect, it being intended that any such statement delivered pursuant hereto
    may be relied upon by Lessor and by mortgagee or prospective mortagee of
    any mortgage affecting the building or the building and the land.

    If any proceedings are brought for the foreclosure of any encumbrance
    affecting the demised Premises, or the power of sale under any deed of
    trust made by Lessor covering the demised Premises, Lessee shall attorn to
    the Purchaser upon any such foreclosure of sale and recognize such
    Purchaser as Lessor under this Lease, provided however, that unless Lessee
    shall be in default, any such attornment or subordination as provided in

    of this Lease, and Lessee's use and quiet enjoyment of the premises shall
    continue undisturbed.

    (d)  Time - Time is of the essence of this Lease and each and all of its
    provisions in which performance is a factor.

    (e)  Successors  and Assigns - The covenants and conditions herein
    contained, subject to the provisions as to assignment, apply to and bind
    the heirs, successors, executors, administrators and assigns of the parties
    hereto.


                                          16
<PAGE>

    (f)  Recordation - Neither Lessor nor Lessee shall record this Lease or a
    short form memorandum hereof without the prior written consent of the other
    party.

    (g)  Quiet Possession - Upon Lessee paying the rent reserved hereunder and
    observing and performing all of the covenants, conditions and provisions on
    Lessee's part to be observed and performed hereunder, Lessee shall have
    quiet possession of the Premises for the entire term hereof, subject to all
    the provisions of this Lease.

    (h)  Late Charges - Lessee hereby acknowledges that late payment by Lessee
    to Lessor of rent or other sums due hereunder will cause Lessor to incur
    costs not contemplated by this Lease, the exact amount of which will be
    extremely difficult to ascertain.  Such costs include but are not limited
    to, processing and accounting charges, and late charges which may be
    imposed upon Lessor by terms of any mortgage or trust deed covering the
    Premises.  Accordingly, if any installment of  rent or of a sum due from
    Lessee shall not be received by Lessor or Lessor's assignee, in the event
    of rent on the tenth (10th) of the month, or in the event of any other sum
    due within ten (10) days after written demand, then Lessee shall pay to
    Lessor a late charge equal to six percent (6%) of such overdue amount.
    However, if said period be extended beyond fifteen (15) days, then Lessee
    shall pay to Lessor a late charge equal to twelve percent (12%) per annum
    of such overdue amount.  The parties hereby agree that such late charges
    represent a fair and reasonable estimate of the cost that Lessor will incur
    by reason of the late payment by Lessee.  Acceptance of such late charges
    by Lessor shall in no event constitute a waiver of Lessee's default with
    respect to such overdue amount, nor prevent Lessor from exercising any of
    the other rights and remedies granted hereunder.

    (i)  Prior Agreements - This Lease contains all of the agreements of the
    parties hereto with respect to any matter covered or mentioned in this
    Lease, and no prior agreements or understanding pertaining to any such
    matters shall be effective for any purpose.  No provision of this Lease may
    be amended or added to except by an agreement in writing signed by the
    parties hereto to their respective successors of interest.  This Lease
    shall not be effective or binding on any party until fully executed by both
    parties hereto.

    (j)  Variation in Pronouns - All pronouns and variations thereof shall be
    deemed to refer to the


                                          17
<PAGE>

    masculine, feminine, singular or plural as the identity of the person or
    persons may require.

    (k)  Inability to Perform - This Lease and the obligations of the Lessee
    hereunder shall not be affected or impaired because the Lessor is unable to
    fulfill any of its obligations hereunder or is delayed in doing so, if such
    inability or delay is caused by reason of strike, labor troubles, acts of
    God, or any other cause beyond the reasonable control of the Lessor.

    (l)  Separability - Any provisions of this Lease which shall prove to be
    invalid, void or illegal shall in no way affect, impair, or invalidate any
    other provisions hereof and such other provisions shall remain in full
    force and effect.

    (m)  Cumulative Remedies - No remedy or election hereunder shall be deemed
    exclusive but shall, whenever possible, be cumulative with all other
    remedies at law or in equity.

    (n)  Choice of Law - This Lease shall be interpreted and governed by the
    laws of the State of Washington as they exist on even date.

    (o)  Proportionate Share - For this Lease proportionate share to be 24.2%
    and will be adjusted for additional space or additional improvements if
    necessary.

33. LEASE OPTION

    conditions as this present Lease.  Lessee must provide Lessor written

Securities and Exchange Commission
450 Fifth Street N.W.
Washington, DC 20549

Dear Sirs:

We have reviewed the attached disclosure for inclusion in the RODI Power 
Systems, Inc. SB-2 Initial Public Offering document and provide the following 
clarifications.

We have previously audited, in accordance with generally accepted auditing 
standards, the balance sheets of RODI Power Systems, Inc. (a Washington 
corporation in the development stage) as of December 31, 1994 and 1995, and 
the related statements of operations, common stock subject to rescission and 
stockholders deficit and cash flows for the period from July 20, 1987 
(inception) to December 31, 1994, the year ended December 31, 1995, and the 
period from July 20, 1987 (inception) to December 31, 1995, and have rendered 
out report dated January 17, 1996. We have not performed any audit procedures 
since January 17, 1996, or audited any financial statements of RODI Power 
Systems, Inc. subsequent to December 31, 1995.

Our report on the above referenced financial statements was prepared assuming 
the Company would continue as a going concern. As discussed in the Notes to 
the financial statements, the Company is a development stage enterprise, with 
limited capital resources, and has incurred accumulated losses of $2,568,290 
as of December 31, 1995. Additionally, as discussed in the Notes to the 
financial statements, the Company had sold common stock to investors without 
registering the securities for sale with the appropriate federal and state 
regulatory agencies and was in violation of federal and state securities 
laws. These factors raised substantial doubt about the Company's ability to 
continue as a going concern. The financial statements did not include any 
adjustments that might result from the outcome of these uncertainties.

We were engaged by the Company to perform an audit of its financial 
statements in connection with a rescission offer, which was subsequently 
completed. On August 26, 1996, we notified the Company of our decision not to 
seek appointment as the Company's independent auditors on an ongoing basis. 
There were no disagreements with management on any matter of accounting 
principles or practices, financial statement disclosure, or auditing scope or 
procedure.


Very truly yours, 

/s/ Arthur Andersen LLP
