PROSPECTUS                        SUBJECT TO COMPLETION DATED AUGUST 10, 1998
- ------------------------------------------------------------------------------

INFORMATION CONTAINED HEREIN IS SUBJECT TO COMPLETION OR AMENDMENT.  A
REGISTRATION STATEMENT RELATING TO THESE SECURITIES HAS BEEN FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION.  THESE SECURITIES MAY NOT BE SOLD NOR MAY
OFFERS TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT BECOMES
EFFECTIVE.  THIS PROSPECTUS SHALL NOT CONSTITUTE AN OFFER TO SELL OR THE
SOLICITATION OF AN OFFER TO BUY NOR SHALL THERE BE ANY SALE OF THESE
SECURITIES IN ANY STATE IN WHICH SUCH OFFER, SOLICITATION OR SALE WOULD BE
UNLAWFUL PRIOR TO REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF
ANY STATE.

                        CET ENVIRONMENTAL SERVICES, INC.
                        1,161,316 Shares of Common Stock

     This Prospectus relates to 1,161,316 shares of common stock, no par value
(the "Common Stock" or "Shares") of CET Environmental Services, Inc., a
California corporation (the "Company"), to be offered and sold from time to
time for the accounts of the Selling Shareholders set forth herein (the
"Selling Shareholders").  All of the 1,161,316 shares of Common Stock being
offered hereby are being registered at the Company's expense pursuant to
contractual obligations of the Company incurred in connection with a private
placement of its 4% Convertible Preferred Stock and common stock purchase
warrants under the Securities Act of 1933, as amended.

     Up to 1,126,316 shares of Common Stock which are being offered by the
Selling Shareholders are issuable upon the conversion of 4% Convertible
Preferred Stock (the "Preferred Stock") held by the Selling Shareholders.  The
Preferred Stock is convertible into shares of Common Stock based on the stated
value of $1,000 per share of Preferred Stock divided by the Conversion Price
on the Conversion Date.  The Conversion Price will be equal to 85% of the
lowest closing price of the Common Stock as reported on the American Stock
Exchange during the six trading days immediately preceding the Conversion
Date.  However, in no event will the Conversion Price exceed $3.35.  The
Company has the option, upon receipt of a Conversion Notice, to allow the
conversion, in whole or in part, or to pay the holder in cash in an amount
equal to the number of shares of Common Stock that would have been issued
multiplied by the closing price on the American Stock Exchange on the day
prior to the Conversion Date.  The Preferred Stock may be redeemed by the
Company under certain circumstances.  Any shares of Preferred Stock
outstanding on June 30, 2001, will be automatically converted into Common
Stock.

     This Prospectus also covers the offering by the Selling Shareholders of
up to 35,000 shares of Common Stock that are issuable upon exercise of common
stock purchase warrants (the "Warrants") which the holders of the Preferred
Stock received together with their Preferred Stock.  Each Warrant is
exercisable to purchase one share of Common Stock at $3.00 per share during
the period commencing on July 24, 1999 and ending on December 31, 2001.  The
Warrants may be exercised through the payment of cash or, at the option of the
holder, through a "cashless exercise" by tendering the warrant certificate to
the Company to receive a number of shares of Common Stock equal in market
value to the difference between the market value of the shares of Common Stock
issuable upon exercise of the Warrants being tendered and the total cash
exercise price thereof.

                 The date of this Prospectus is __________, 1998.



     The Company will receive no part of the proceeds of sales from the
offering of Shares by the Selling Shareholders.  The Company could receive up
to $105,000 from the exercise of the Warrants held by the Selling
Shareholders.  The Company has no knowledge of any Selling Shareholder
actually intending to sell any Shares.

     The shares of Common Stock may be sold by the Selling Shareholders in
underwritten transactions, in ordinary brokerage transactions, in transactions
in which brokers solicit purchases, in negotiated transactions, or in a
combination of such methods of sale, at market prices prevailing at the time
of sale, at prices relating to such prevailing market prices or at negotiated
prices.  See "PLAN OF DISTRIBUTION."  All expenses of registration incurred in
connection with this offering are being borne by the Company, but all selling
and other expenses incurred by the Selling Shareholders will be borne by such
Selling Shareholders.  None of the Common Stock offered pursuant to this
Prospectus has been registered prior to the filing of the Registration
Statement of which this Prospectus is a part.

     The Common Stock is listed on the American Stock Exchange under the
symbol "ENV".  On August 7, 1998, the closing sale price of the Common Stock,
as reported on the American Stock Exchange, was $1.75 per share.

     THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK.  SEE
"RISK FACTORS" BEGINNING ON PAGE 5 OF THIS PROSPECTUS.

     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                                  THE COMPANY

     CET Environmental Services, Inc. (the "Company") was incorporated in
February 1988 under the name "Thorne Environmental, Inc." to conduct business
in environmental consulting, engineering, remediation and construction.   The
Company's initial growth resulted from its successful performance of emergency
response cleanup services in certain western states and the Trust Territory of
the Pacific Islands for the U.S. Government.  The Company has since developed
a broad range of expertise in non-proprietary technology-based environmental
remediation and water treatment techniques for both the public and private
sectors throughout North and South America and the Trust Territory of the
Pacific Islands.  The Company was purchased by its existing majority
shareholders in November 1991, and for the last six years has engaged in a
program of expansion through internal client development and add-on contracts,
the acquisition of personnel and assets in desirable geographic locations, and
the acquisition of smaller companies involved with target growth technologies.
The Company has built a large backlog of government work through the award of
several multi-year contracts primarily with the Environmental Protection
Agency and the Department of Defense.  The Company has achieved and maintains
a balance between its commercial and government sector business through an
aggressive industrial marketing strategy. To date, the Company has performed
remediation services for both public and private sector customers at more than
500 sites.

     The Company's strategy has been to distinguish itself in the market by
providing full service environmental contracting, municipal and industrial
water and wastewater treatment, and emergency response services.  Through
several major government contracts and a diversified commercial client base,
the Company provides turnkey waste management for a complete range of water,
soil and air pollution issues.  The Company's personnel have developed
expertise in a broad range of remediation techniques such as bioremediation,
bioventing, vapor extraction, gas/air sparging, thermal desorption, soil
washing and groundwater remediation systems.  The Company also offers a broad
range of services in support of municipal and industrial water and wastewater
treatment, military base closures, and other operations with significant
environmental components.  The Company believes it has gained a solid
reputation for promptly providing cost effective and innovative remediation
solutions.

     In November 1996, the Company relocated its corporate headquarters to
Englewood, Colorado from Tustin, California to be more centrally located for
its expanding business.  The Company also maintains offices in Tustin,
California; Richmond, California; Portland, Oregon; Edmonds, Washington;
Pasadena, Texas; New Orleans, Louisiana; Jackson, Mississippi; and Mobile,
Alabama.

     The Company's headquarters are located at 7670 South Vaughn Court, Suite
130, Englewood, Colorado 80112, and its telephone number is (303) 708-1360.
The Company's fax number is (303) 708-1349 and its internet address is

                                  RISK FACTORS

     An investment in the securities being offered by this Prospectus involves
a high degree of risk.  In addition to the other information contained in this
Prospectus or incorporated herein by reference, prospective investors should
carefully consider the risk factors discussed below before purchasing the
shares of Common Stock offered hereby.

                                       5



     This Prospectus contains and incorporates by reference forward-looking
statements within the meaning of the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995. Such statements are based on
management's current expectations and are subject to a number of factors and
uncertainties which could cause actual results to differ materially from those
described in the forward-looking statements. Reference is made in particular
to the description of the Company's plans and objectives for future
operations, assumptions underlying such plans and objectives and other
forward-looking statements included or incorporated in this Prospectus.
Factors which could cause such results to differ materially from those
described in the forward-looking statements include those set forth in the
risk factors below.

     1.   COSTS OF COMPLIANCE WITH, AND POTENTIAL LIABILITY UNDER,
ENVIRONMENTAL LAWS AND REGULATIONS.  Due to the nature of the Company's
business and the intense regulatory climate in which it operates, the services
of the Company are subject to extensive federal, state and local laws and
regulations which are constantly changing. Such regulations impose stringent
guidelines on companies which handle hazardous materials as well as other
companies involved in various aspects  of  the environmental remediation
services industry. Failure to comply with applicable federal, state and local
regulations could result in substantial costs to the Company, the imposition
of penalties or in claims not covered by insurance, any of which could have a
material adverse effect on the Company's business.

     In addition to the burdens imposed on Company operations by various
environmental regulations, federal law imposes strict joint and several
liability upon present and former owners and operators of facilities that
release hazardous substances into the environment and the generators and
transporters of such substances as well as persons arranging for the disposal
of such substances. All such persons may be liable for the costs of waste site
investigation, waste site clean up, natural resource damages and related
penalties and fines. Such costs can be very substantial.

     Environmental remediation operations may expose the Company's employees
and others to dangerous and potentially toxic quantities of petroleum or other
hazardous products. Such products can cause cancer and other debilitating
diseases. Although the Company takes extensive precautions to minimize worker
exposure and has not experienced any such claims from workers or others, there
can be no assurance that the Company will avoid liability to persons who
contract diseases which may be related to such exposure. Such persons
potentially include the Company's employees, persons occupying or visiting
facilities in which contaminants are being, or have been, removed or stored,
persons in surrounding areas, and persons engaged in the transportation and
disposal of waste material. In addition, the Company is subject to general
risks inherent in the construction industry. The Company may also be exposed
to liability from the acts of its subcontractors or other contractors on a
work site.

     Currently, the Company has $6,000,000 per occurrence and $7,000,000
aggregate comprehensive general liability insurance coverage. In addition, the
Company carries environmental impairment liability insurance in the amount of
$2,000,000 per occurrence with a $2,000,000 aggregate.  Errors and omissions
liability insurance for petroleum and chemical exposure for claims made in the
coverage period is also provided.  While the Company has never been subject to
a claim relating to petroleum/chemical exposure and believes that its current
coverage is adequate, there can be no assurance that the Company will be able
to maintain its existing coverage, that claims will not exceed the amount of
insurance coverage or that there will not be claims relating to prior periods
that were not covered by insurance, any of which could have a material adverse
effect upon the Company. Because of the nature of the Company's operations and


the industry in which it operates, the potential for liability and the extent
of such potential liability is very substantial. Any such liability could have
a material adverse impact on the Company's business and financial condition.

     2.   DEPENDENCE ON CONTINUED ENVIRONMENTAL REGULATION.  The growth of the
environmental remediation services industry, as well as the growth of the
Company, has been largely attributable to, and tracks the increase in,
environmental regulation since the 1970s and the response of governmental and
commercial entities and financial institutions to public concern with
environmentally contaminated facilities. The demand for environmental
remediation services has been largely the result of facility and property
owners attempting to comply with, or avoid liability under, existing or newly
imposed environmental regulations at the federal, state and local levels.
Because of the burden imposed on industry in complying with such regulations,
efforts have been made by various groups to seek the relaxation or repeal of
certain forms of environmental regulation. While such efforts have been
largely unsuccessful to date, there can be no assurance that the scope or
growth of such regulation will not be curtailed in the future. Any relaxation
of environmental regulation may result in a decline in demand for
environmental remediation services and may adversely affect the operations of
the Company. For example, the Resource Conservation and Recovery Act ("RCRA")
mandates that by December 31, 1998, every single walled underground storage
tank ("UST") in the United States must be removed and replaced with a double
walled tank, and that any environmental damage to the soil or water caused by
tank leakage must be remediated. As a result, the Company's business in UST
removals and installations will likely be reduced after that date.  Management
doesn't expect that this reduction after December 31, 1998, will have a
material adverse effect on the Company because this line of business
represents less than ten percent of the Company's business at the present
time.

     3.   DEPENDENCE ON MAJOR CUSTOMER.  The Company is dependent upon its
relationship and contract with the EPA which accounted for approximately 38.8%
and approximately 20% of the Company's revenues in 1997 and 1996,
respectively.  While the Company intends to increase the amount of work
performed for entities other than the EPA and thereby reduce its dependence on
the EPA, the Company will continue to be significantly dependent on EPA
contracts for the foreseeable future.

     4.   DEPENDENCE ON SPENDING LEVELS OF GOVERNMENTAL AND INDUSTRIAL
ENTITIES.  Because of the nature of sites requiring environmental remediation
services, the growing public emphasis on environmental matters and the cost of
environmental remediation services, a significant portion of all funds spent
for such services has been spent by governmental agencies and large industrial
concerns. While third party reimbursement may be sought in various cleanups,
most Superfund cleanups as well as weapons and other nuclear facility cleanups
involve significant spending by governmental agencies. As budget constraints
and emphasis on employment, international competition and other considerations
grow, certain governmental agencies and industrial concerns may choose to
delay or curtail expenditures for environmental remediation services. Any
curtailment or delays in spending for environmental remediation services by
governmental agencies or large industrial concerns can be expected to have a
material adverse effect on the environmental remediation services industry
generally, and on the operations and financial results of the Company.

     5.   MANAGEMENT OF GROWTH.  The Company has experienced a period of rapid
growth in its operations. This growth has resulted in an increase in the level
of responsibility for members of the Company's management team. Few of these
managers have had experience managing businesses which have experienced a rate
of growth similar to that of the Company. The Company's ability to manage
growth successfully will require it to continue to improve its operational,

                                       6



management and financial systems and controls and to expand, train, manage and
retain its employee base. Failure of the Company's management to do so could
have a material adverse effect on the Company's business, operating results
and financial condition.

     6.   BUSINESS SUBJECT TO WEATHER CONDITIONS.  While the Company provides
its services on a year round basis, the Company's services provided outdoors
or outside of a sealed environment may be adversely affected by inclement
weather conditions. Extended periods of rain, cold weather or other inclement
weather conditions may result in delays in commencing or completing projects,
in whole or in part. Any such delays may adversely affect the Company's
operations and financial results and may adversely affect the performance of
other projects due to scheduling and staffing conflicts.

     7.   DEPENDENCE ON ABILITY TO SECURE BONDING.  In order to successfully
bid on and secure contracts to perform environmental remediation services of
the nature offered by the Company, the Company oftentimes must provide surety
bonds with respect to each respective project. Thus the number and size of
contracts which the Company can perform is directly dependent upon the
Company's ability to obtain bonding which, in turn, is dependent upon the
Company's net worth and liquid working capital. There can be no assurance that
the Company will have adequate bonding capacity to bid on all of the projects
which it would otherwise bid upon were it to have such bonding capacity or
that it will in fact be successful in obtaining additional contracts on which
it may bid.

     8.   FIXED PRICE AND PER UNIT CONTRACTS.  Historically, less than 10% of
the Company's remediation contracts are on a fixed price or per unit basis.
Cost overruns on projects covered by such contracts due to such things as
unanticipated price increases, unanticipated problems, inefficient project
management, inaccurate estimation of labor or material costs or disputes over
the terms and specifications of contract performance could have a material
adverse effect on the Company and its operations. There can be no assurance
that cost overruns will not occur in the future and have a material adverse
effect on the Company. In addition, in order to remain competitive in the
future, the Company may have to agree to enter into more fixed price and per
unit contracts than in the past.

     9.   LACK OF SIGNIFICANT OPERATING HISTORY.  The Company has been in
existence since 1988 and was acquired by current management in November 1991.
As such, the Company is subject to many of the risks common to enterprises
with a limited operating history, including potential under capitalization,
limitations with respect to personnel, financial and other resources and
limited customers and revenues. There is no assurance that the Company's
activities will be successful and the likelihood of success must be considered
in light of its current stage of development.

     10.  FUTURE CAPITAL NEEDS AND UNCERTAINTY OF ADDITIONAL FINANCING.  The
Company's long term capital requirements will depend on many factors,
including, but not limited to, cash flow from operations, the level of capital
expenditures, working capital requirements and the growth in its business.
Historically, the Company has relied upon commercial borrowings, a public
offering, borrowings from shareholders and affiliates of shareholders and
retained earnings to fund its operations and capital needs. The Company has
established a line of credit with a commercial bank which provides up to $9
million in credit depending on the amount of eligible accounts receivable and
contracts in progress. As of June 30, 1998, there was $7,996,568 outstanding
under this line of credit.  The Company may need to incur additional
indebtedness to fund the capital needs related to its growth. To the extent
additional debt financing cannot be raised on acceptable terms, the Company
may need to raise additional funds through public or private equity

                                       7



financings. No assurance can be given that additional equity financing will be
available or that, if available, the terms of such financing will be favorable
to the Company or to its shareholders without substantial dilution of their
ownership and rights. If adequate funds are not available, the Company may be
required to curtail its future operations significantly or to forego market or
expansion opportunities.

     11.  COMPETITION.  Competition in the environmental remediation services
industry is intense, and the success of the Company is dependent upon its
ability to secure contracts. Government, state and local contracts are awarded
based upon competitive bidding, and the Company is not always the lowest
bidder. The Company's future success will be dependent upon the Company's
ability to competitively bid contracts and to perform them on a profitable
basis. In addition, the Company will need to grow in order to remain
competitive with larger competitors.

     The industry is dominated by a few large engineering construction firms.
Such firms are called upon to serve as primary contractors and consultants on
a large portion of the federal and state government projects. Additionally,
many smaller engineering firms, construction firms, consulting firms and other
specialty firms have entered the environmental remediation services industry
in recent years and additional firms can be expected to enter into the
industry in the future. Many of the firms with which the Company competes in
the environmental remediation services industry have significantly greater
financial resources and more established market positions than the Company.
While management believes that the Company's experience and expertise in the
broad range of services which it offers allows the Company to compete
successfully, there can be no assurance that this will continue or that other
firms will not expand into or develop expertise in the areas in which the
Company specializes, thus increasing competition to the Company.

     12.  CONCENTRATION OF CREDIT RISK.  The Company contracts with a limited
number of customers which are involved in a wide range of industries. A small
number of customers may therefore be responsible for a majority of revenues at
any time. While management assesses the credit risk associated with each
proposed customer prior to the execution of a definitive contract, no
assurances can be given that such assessments will be correct and that the
Company will not sustain substantial, noncollectible accounts receivable.

     13.  DEPENDENCE ON EXECUTIVE MANAGEMENT AND OTHER QUALIFIED PERSONNEL.
The operations of the Company are substantially dependent on its executive
officers who are also its principal shareholders and directors. The Company
has no employment contracts with these persons. The loss of their services
could have a material adverse effect on the Company. The Company's further
success will also depend significantly on its ability to attract and retain
additional skilled personnel, including highly trained technical personnel,
project managers and supervisors. The Company believes it currently has
adequate qualified supervisory personnel, but there is no assurance that
experienced and qualified management level personnel will be available to the
Company in the future to fill positions as needed.

     14.  CONTROL BY OFFICERS, DIRECTORS AND MAJOR SHAREHOLDERS.  Officers and
directors and principal shareholders of the Company, beneficially own an
aggregate of approximately 55% of the issued and outstanding shares of the
Company's Common Stock. Under California law, shareholders of the Company have
cumulative voting rights; however, it is likely that despite such rights,
present management and principal shareholders will continue to be able to
control the Board of Directors of the Company.


                                       8


     15.  DIVIDENDS.  The Company does not anticipate paying any cash
dividends for the foreseeable future. The Company expects that future
earnings, if any, will be used to finance growth. No person seeking dividend
income from an investment should invest in this offering.

                                 RECENT EVENTS

     In July 1998, the Company announced that its Water Quality Management
Corporation (WQM) subsidiary had been awarded a contract to create a new
wastewater system for two communities and a number of large agricultural users
in the Texas Panhandle.  The contract, which is expected to be completed
within two years, includes the design, construction and operation of a new
wastewater treatment plant as a joint privatization effort involving the
cities of Cactus and Etter, Texas and three major industrial facilities in an
area north of Amarillo, Texas.  Phase I of the project, which is expected to
be performed over the next eight months, is valued at approximately $3
million.

     In July 1998, the Company's Board of Directors elected George Pratt to
serve as an additional Director of the Company. Mr. Pratt (age 66) is the
former Chairman and Chief Executive Officer of Computer Automation, Inc.  He
currently also serves as a Director of Global Spectrum, Inc. and Wireless
International Corporation, Ltd.

     In July 1998, the Company announced that it had engaged the investment
banking firm of Sanders Morris Mundy to assist the Company to explore
acquisition and divestiture strategies including further expansion into the
water and wastewater treatment market.  The Company further announced that it
was committed to repositioning itself toward the water and wastewater
treatment segments of its business.

     In June 1998, the Company announced that it is part of a team which had
been awarded a $250 million remedial action contract for environmental
restoration projects on naval facilities in four western states.  The
Company's portion of this contract is estimated at $30 million.  The contract
is for a period of seven years and initial work is scheduled to begin in
October 1998.

     Effective June 26, 1998, John G-L Hopkins, who has served as Vice
President - Federal Programs, resigned as an officer and employee of the
Company.  Mr. Hopkins also served as a Director of the Company until June 2,
1998, when he declined to stand for reelection.  Mr. Hopkins has agreed to
continue to provide services to the Company on a consulting basis, as needed.

     As a result of the loss incurred during the quarter ended March 31, 1998,
the Company was in breach of loan covenants with the National Bank of Canada
relating to a $9,000,000 credit line and $1,000,000 equipment term loan.  The
loan covenants require the Company to break even and maintain a certain ratio
between operating income and interest expense each quarter.  The Company is
not in default on any loan payments due to the Bank.  In June 1998, the
Company received a written waiver from the Bank concerning the breach for the
quarter ended March 31, 1998.

     On March 2, 1998, the Company's WQM subsidiary entered into a Service
Agreement with the Town of Keystone, South Dakota to design, build and operate
for 20 years a municipal wastewater treatment plant.  In conjunction with this
Agreement, Keystone issued economic development revenue bonds totaling
$2,710,000.  The proceeds of this bond issue were loaned by Keystone to WQM
for construction of the facility.  This loan will be repaid from payments made
by Keystone to WQM for wastewater treatment services provided under the
Service Agreement.

                                USE OF PROCEEDS

     To the extent that any of the Warrants are exercised for cash, up to
$105,000 may be received by the Company.  Any net proceeds received from the
exercise of the Warrants will be used for general corporate purposes.

                              SELLING SHAREHOLDERS
 
     1,161,316 shares are being offered for resale by certain shareholders of
the Company.  Up to 1,126,316 of those shares are issuable upon conversion by
the holders of 4% Convertible Preferred Stock ("Preferred Stock").  Up to
35,000 shares are issuable upon exercise of the Warrants held by the holders
of the Preferred Stock.  All shares, to the extent they are being offered, are
being offered for the account of the following shareholders and their donees
or pledgees (the "Selling Shareholders").

     The following table sets forth certain information with respect to the
Selling Shareholders for whom the Company is registering the Common Stock for
resale to the public, including: (i) the number of shares of Preferred Stock
owned by each Selling Shareholder, (ii) the maximum number of shares issuable
upon conversion of the Preferred Stock,(iii) the number of shares issuable
upon exercise of the Warrants, (iv) the percentage of class owned (assuming
the maximum number of shares were issued upon conversion); and (v) the maximum
number of shares offered by each Selling Shareholder (assuming the maximum
number of shares were issued upon conversion).  The Company has no knowledge
of the intentions of any Selling Shareholder to actually sell any of the
shares listed under the columns "Maximum Shares Issuable Upon Conversion" or
"Shares Issuable Upon Exercise of Warrants." There are no material
relationships between any of the Selling Shareholders and the Company other
than as disclosed below.

No information is given with respect to beneficial ownership after the

converted into Common Stock, as well as the number of shares issuable upon
conversion, is indeterminate.
<FN2>
Assumes the conversion of all of the Preferred Stock into the maximum number
of shares of Common Stock that the Company will allow to be issued in such
conversions.  In order to comply with American Stock Exchange rules, the
Company will only allow the Preferred Stock to be converted into a number of
shares of Common Stock which would be less than 20% of the Company's

                                       10



outstanding Common Stock.  In the event that the Company receives any requests
to convert Preferred Stock which would result in a greater number of shares
being issued, the Company will exercise its right to pay the holder cash equal
to the market value of the shares of Common Stock which would have been issued
instead of issuing such shares.
<FN3>
Assumes the conversion of all of the Preferred Stock and the exercise all of

     The information concerning the Selling Shareholders may change from time
to time and will be set forth in Supplements to this Prospectus.

                              PLAN OF DISTRIBUTION

     The purpose of this Prospectus is to permit the Selling Shareholders, if
they desire, to offer and sell up to 1,161,316 Shares (the "Selling
Shareholder Shares") at such times and at such places as the Selling
Shareholders choose.

     The decision to convert the Preferred Stock into Shares, to exercise the
Warrants, or to sell any shares, is within the sole discretion of the holders
thereof.  There can be no assurance that any of the Preferred Stock will be
converted or any of the Warrants will be exercised, or any shares will be sold
by the Selling Shareholders.

     The distribution of the Selling Shareholder Shares may be effected from
time to time in one or more transactions.  Any of the Selling Shareholder
Shares may be offered for sale, from time to time, by the Selling
Shareholders, or by permitted transferees or successors of the Selling
Shareholders, on the American Stock Exchange, or otherwise, at prices and on
terms then obtainable, at fixed prices, at prices then prevailing at the time
of sale, at prices related to such prevailing prices, or in negotiated
transactions at negotiated prices or otherwise.  The Selling Shareholder
Shares offered hereby may be sold by one or more of the following: (i) through
underwriters, or through underwriting syndicates; (ii) through one or more
dealers or agents (which may include one or more underwriters), including, but
not limited to:  (a) block trades in which the broker or dealer acts as
principal to facilitate the transactions; (b) purchases by a broker or dealer
as principal and resale by such broker or dealer for its account pursuant to
this Prospectus; (c) ordinary brokerage transactions; and (d) transactions in
which the broker solicits purchasers; (iii) directly to one or more
purchasers; or (iv) a combination of these methods.  The names of any
underwriters or agents involved in the sale of the Selling Shareholder Shares
will be set forth in a Prospectus Supplement.  In connection with the
distribution of the Selling Shareholder Shares or otherwise, the Selling
Shareholders may enter into hedging transactions with broker-dealers or other
financial institutions.  In connection with such transactions, broker-dealers
or other financial institutions may engage in short sales of Common Stock in
the course of hedging the positions they assume with the Selling Shareholders.
The Selling Shareholders may also sell Common Stock short and redeliver the
shares to close out such short positions.  The Selling Shareholders may also
enter into options or other transactions with broker-dealers or other
financial institutions which require the delivery to such broker-dealers or
other financial institutions of the Selling Shareholder Shares, which shares
such broker-dealers or financial institutions may resell pursuant to this
Prospectus (as supplemented or amended to reflect this transaction).  The
Selling Shareholders may also pledge the Selling Shareholder Shares registered
hereunder to a broker-dealer or other financial institution and, upon a
default, such broker-dealer or other financial institution may effect sales of
the pledged shares pursuant to this Prospectus (as supplemented or amended to

                                       11



reflect such transaction).  In addition, any Selling Shareholder Shares
covered by this Prospectus that qualify for sale pursuant to Rule 144 under
the Securities Act may be sold under Rule 144 rather than pursuant to this
Prospectus.

     The Selling Shareholders or their underwriters, dealers or agents may
sell the Selling Shareholder Shares to or through underwriters, dealers or
agents, and such underwriters, dealers or agents may receive compensation in
the form of discounts or concessions allowed or reallowed.  Underwriters,
dealers, brokers or other agents engaged by the Selling Shareholders may
arrange for other such persons to participate.  Any fixed public offering
price and any discounts and concessions may be changed from time to time.
Underwriters, dealers and agents who participate in the distribution of the
Selling Shareholder Shares may be deemed to be underwriters within the meaning
of the Securities Act, and any discounts or commissions received by them or
any profit on the resale of shares by them may be deemed to be underwriting
discounts and commissions thereunder. The proposed amounts of Selling
Shareholder Shares, if any, to be purchased by underwriters and the
compensation, if any, of underwriters, dealers or agents will be set forth in
a Prospectus Supplement.

     Unless granted an exemption by the Commission from Rule 10b-6 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), or unless
otherwise permitted under Rule 10b-6A, the Selling Shareholders will not
engage in any stabilization activity in connection with the Company's
securities, will furnish each broker or dealer engaged by the Selling
Shareholders and each other participating broker or dealer the number of
copies of this Prospectus required by such broker or dealer, and will not bid
for or purchase any securities of the Company or attempt to induce any person
to purchase any of the Company's securities other than as permitted under the
Exchange Act.

     The Company will not receive any proceeds from any sales of the Selling
Shareholder Shares, but will receive the proceeds from the exercise of the
warrants held by the Selling Shareholders, which proceeds, if any, will be
used for general corporate purposes.

     In connection with the registration by the Company, the Company shall use
its best efforts to prepare and file with the Commission such amendments and
supplements to the registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective and to comply with the provisions of the Securities Act with respect
to the disposition of the Shares covered by the registration statement for the
period required to effect the distribution of such Shares.

     The Company is paying certain expenses (other than commissions and
discounts of underwriters, dealers or agents) incident to the offering and
sale of the Shares to the public, which are estimated to be approximately
$12,000.  If the Company is required to update this Prospectus during such
period, it may incur additional expenses in excess of the amount estimated
above.

     In order to comply with certain states' securities laws, if applicable,
the Shares will be sold in such jurisdictions only through registered or
licensed brokers or dealers.  In certain states the Shares may not be sold
unless they have been registered or qualify for sale in such state or an
exemption from registration or qualification is available and is complied
with.

ITEM 17.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

          (i)  To include any prospectus required by Section 10(a)(3) of the
1933 Act;

          (ii)  To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
registration statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any

                                II-1


deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) ([Section] 230.424(b) of this chapter) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.

          (iii)  To include any material information with respect to the plan
of distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

Provided, however, that paragraphs (l)(i) and (l)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the registrant pursuant to Section 13
or Section 15(d) of the 1934 Act that are incorporated by reference in the
registration statement.

     (2)  That, for the purpose of determining any liability under the 1933
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination
of the offering.
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the registrant's
annual report pursuant to section 13(a) or section 15(d) of the 1934 Act (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to section 15(d) of the 1934 Act) that is incorporated by reference
in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     Insofar as indemnification for liabilities arising under the 1933 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 1933 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 1933 Act and will be governed by the final
adjudication of such issue.
