                        3,036,354 SHARES OF COMMON STOCK

     This Prospectus relates to the public offer and sale by certain
shareholders (the "Selling Shareholders") of an aggregate of 3,036,354 shares
(the "Shares") of $0.01 par value common stock (the "Common Stock") of Earth

or in other transactions negotiated by the Selling Shareholders.  Any such sale
of Common Stock by Selling Shareholders must be accompanied by, or follow the
delivery of, a prospectus filed with a current registration statement relating
to the Common Stock being offered, unless a Selling Shareholder elects to rely
on Rule 144 or another exemption from the registration requirements in
connection with a particular transaction.  The Selling Shareholders and any
broker, dealer, or agent that participates with the Selling Shareholders in the
sale of Common Stock  offered hereby may be deemed "underwriters" within the
meaning of the Securities Act of 1933, as amended ( the "Securities Act"), and
any commission or discounts received by them and any profit on the resale of the
Common Stock purchased by them may be deemed to be underwriting commissions
under the Securities Act. (See "SELLING STOCKHOLDERS" and "PLAN OF
DISTRIBUTION").

The Company's Common Stock is traded in the over-the-counter market and is
quoted on NASDAQ's  SmallCapSM Market ("Nasdaq") under the symbol "ESCI".  On
_______, 1997, the closing price of the Common Stock on Nasdaq was $____ per

THE RISK OF LOSS OF THEIR ENTIRE INVESTMENT. (SEE "RISK FACTORS" BEGINNING ON
PAGE 7 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 SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.

(1)  The price per share for the securities offered by the Selling Shareholders
is estimated at the closing sales price quoted by Nasdaq for the Common Stock at
$2.75 on April 14, 1997.  The Common Stock may be offered at the current market
price, which may vary through the period during which the securities may be
offered, or at such other prices as may be negotiated by the Selling Shareholder
and the purchaser at the time of sale.
(2)  The securities to be sold by Selling Stockholders may be sold by them or
through or to securities brokers or dealers, which sales may involve the payment
of commissions to the Selling Stockholders.
(3)  Does not reflect expenses of this offering payable by the Company estimated
at $7,000 nor the receipt by the Company of approximately $928,000 on exercise
of options.  (See "PLAN OF DISTRIBUTION" below).

     The Company will not receive any proceeds from the sale of Common Stock by
the Selling Stockholders.  However, the Company would receive proceeds upon
exercise of options held by Selling Stockholders prior to the sale of Common
Stock issuable on such exercise.  (See "USE OF PROCEEDS").  In connection with
this offering, the Company estimates that it will incur costs of approximately
$7,000 for legal, accounting, printing, and other costs.  Any separate costs of
Selling Stockholders will be borne by them.  Commissions or discounts paid in
connection with the sale of securities by the Selling Stockholders will be
determined by negotiations between them and the broker-dealer through or to

dealers' commission or mark up schedule, the size of the transaction, and other
factors.  (See "PLAN OF DISTRIBUTION" below.)

     The Selling Stockholders and any broker, dealer, or agent that participates
with the Selling Stockholders in the sale of the Common Stock offered hereby may
be deemed "underwriters" within the meaning of the Securities Act of 1933, as
amended ( the "Securities Act"), and any commission or discounts received by
them and any profit on the resale of the Common Stock purchased by them may be
deemed to be underwriting commissions under the Securities Act. (See "SELLING
STOCKHOLDERS" and "PLAN OF DISTRIBUTION").

THE COMPANY
Earth  Sciences,  Inc. (the "Company") is a diversified mineral exploration  and
development company specializing in mineral exploration and chemical  processing
with  planned production of purified phosphate products in Calgary.  The Company
was  incorporated under the name of Colorado Central Mines, Inc. in Colorado  in
1957.  Current activities of the Company include (1) modification of its solvent
extraction  facility  in Calgary, Alberta for production of  purified  phosphate
products scheduled to commence in May 1997; (2) continued exploration activities
for   gold   resources  in  Venezuela  including  its  land  contract   covering
approximately  1200 acres; (3) drilling and further geologic evaluation  of  the
Cerro  Gordo property in Inyo County, California (4) the planned acquisition  of
ADA  Environmental Solutions LLC, a company that provides flue gas  conditioning
technology for coal-fired boilers and other applications, and (5) maintenance of
its position in several mining deposits and prospects in the Western US.

The Company's solvent extraction facility in Calgary, Alberta, recovered uranium
from  phosphoric acid during the period from 1983 through 1987.   Uranium  oxide
production was suspended in the fall of 1987 when the adjacent fertilizer  plant
from  which  the  facility  received its feed stock suspended  operations.   The
contract  under  which  the  uranium was sold was  modified  in  1990  to  allow
unrestricted  alternative use of the facility.  An in-house  feasibility  study,
completed in 1995, confirmed the technical and financial
feasibility  of  conversion  of  the facility for  the  production  of  purified
phosphate products.  

                                          5
<PAGE>

facility  to  allow  such  production  has recently  been  completed.   Start-up
activities commenced in April 1997 and first product  was available for sale  at
the end of May 1997.  Contracts for approximately 8,000 tons, or nearly one half
of  the initial projected annual production, have been negotiated.
   
The Company intends to pursue the recovery of other valuable elements in the 
feed stock once routine production and cash flow are achieved.  Initial 
investigation of such recovery potential is estimated to cost between $20,000-
$50,000 and will be funded out of internally generated cash flow. Routine sales
are expected  to  be achieved in July and August, but there can be no 
assurances  that the Company will be able to achieve routine production, the
projected level of sales or cash flow.
    

RECENT DEVELOPMENTS

                           Investor Relation Services
In  August 1996, the Company engaged Corporate Relations Group, Inc. ("CRG")  of
Winter Park, Florida to provide investor relation services for the Company  over
a  5  year  period.   The services include wide circulation advertising,  broker
relations  and  direct  marketing.  In addition to certain  cash  payments,  the
Company  issued  CRG  100,000 shares of Common Stock  and  options  to  purchase
300,000 shares of Common Stock at prices ranging from $2.00 to $4.00 per  share.
This  Prospectus includes the resale of shares of Common Stock held by  CRG  and
those issuable by the Company on the conversion of such options.

                         Sale of Convertible Debentures
In  March  and  April  1997,  the Company issued $3,645,000  of  4%  convertible
debentures  (the  "Debentures") for which the Company received net  proceeds  of
approximately  $3,316,000.   The Debentures were  issued  to  provide  funds  to
complete  the  revamp  and start-up of the Calgary facility  for  production  of
purified phosphate products and the initial obligations associated with the  ADA
acquisition, described below.  Interest on the Debentures is payable  quarterly.
Due  to the difference between the fair market value of the Common Stock on  the
date the Debentures were sold and the conversion price, the Company recognized a
deferred financing cost of $188,000 in the first quarter of 1997 and expects  to
recognize $1,044,000 of such costs in the second quarter of 1997. The Debentures
are  convertible at any time following 45 days after the issuance thereof.   The
deferred  financing cost is being amortized over the 45 day period  ending  when
the Debentures are convertible. Debentures amounting to $550,000 mature on March
31,  1998, while the balance of the Debentures issued mature on March 31,  1999.
The  Debentures  are  convertible into shares of Common Stock  based  on  a  25%
discount  from  the market price of the Common Stock at the time of  conversion,
but  not in excess of $3.13 and $3.25 per share, respectively.  The Company  may
repurchase  the Debentures at a 25% premium if the market price  of  the  Common
Stock  is  below $1.50 per share for any two trading days out of a five  trading
day  period.   This  Prospectus includes the resale of shares  of  Common  Stock
issuable by the Company on the conversion of the Debentures.

                 Acquisition of ADA Environmental Solutions LLC.

On  April  30,  1997, the Company acquired a 51% interest in  ADA  Environmental
Solutions LLC ("ADA") through the purchase of an additional 46.2% interest  from
ADA.   The  Company had previously purchased a 4.8% interest in ADA in  February
1997 by  payment to ADA of $400,000. The 46.2% interest was purchased by payment
to  ADA of $500,000 and a non-interest bearing promissory note in the amount  of
$1,600,000.  The  purchase price for the transaction was  negotiated  among  the
Company  and ADA based on the future anticipated earnings and cash flow of  ADA.
Funds  for  the purchase were from the Company's working capital.   The  Company
also obtained an option to acquire the remaining 49% interest in ADA exercisable
for  a  six  month period commencing May 1, 1998.  The option is exercisable  by
issuance  of   1,715,600  shares  of  Common  Stock  in  exchange  for  all  the
outstanding stock of ADA-ES, Inc., a Colorado corporation, whose only  asset  is
the remaining 49% interest in ADA.

ADA's  only significant asset is its proprietary technology designed  to  reduce
particulate  emissions  from  coal-fired  boilers.  
   
The Company assigned no value to the $324,000 of preproduction costs carried on 
the balance sheet of ADA at the time of acquisition.
    
Management  believes   ADA's proprietary  non-toxic chemical conditioner offers
both technical  and  economic.advantages  over  the hazardous chemicals 
currently being  used.  Michael  D. Durham  of ADA has been elected to the 
Company's Board of Directors as  part  of the transaction.

FORWARD-LOOKING STATEMENTS

In  addition  to  historical  information, this  Prospectus  and  the  documents
incorporated  herein  by  reference  contain  forward-looking  statements.   The
forward-looking  statements contained herein are subject to  certain  risks  and
uncertainties that could cause actual results to differ materially from those in
the  forward-looking  statements.  Factors that might cause  such  a  difference
include,  but are not limited to, those discussed in the section entitled  "RISK
FACTORS"  set forth below.  Investors are cautioned not to place undue  reliance
on these forward-looking statements, which reflect management's analysis only as
of  the  date  of  such  statements.  The Company undertakes  no  obligation  to
publicly   revise  these  forward-looking  statements  to  reflect   events   or
circumstances that arise after the date of such statements.
________________________________________________________________________________

RISK FACTORS
An  investment in the Shares is speculative and involves a high degree of  risk.
In  analyzing  the  offering,  prospective investors  should  read  this  entire
Prospectus  and the information incorporated herein by reference, and  carefully
consider,  among  others, the following risk factors in addition  to  the  other
information set forth elsewhere in this Prospectus.

                     Specifics Risks Related to the Company
No  Dividends.  The Company has paid no cash dividends on its Common  Stock  and
has no present intention of paying cash dividends in the foreseeable future.  It
is  the  present  policy  of the Board of Directors to retain  all  earnings  to
provide for the growth of the Company.  Payments of cash dividends in the future
will   depend,   among  other  things,  upon  the  Company's  future   earnings,
requirements for capital improvements, the operating and financial conditions of
the Company and other factors deemed relevant by the Board of Directors.

Lack  of  Profitability.  While the Company reported net income in fiscal  1995,
the  Company's operating history has resulted in losses from operations  in  the
fiscal  years ending December 31, 1988 through 1994 and in 1996.  While  certain
of  the  Company's operations may be profitable during a given fiscal year,  the
Company's  operations  as a whole may be unprofitable  due  to  exploration  and
development costs on properties from which no revenue is derived, to  continuing
corporate  general  and administrative costs and to interest expense  associated
with long term debt.

Dilutive  Effect of Issuance of Additional Shares on Current Shareholders.   The
Board  of  Directors  has  the authority to authorize  the  offer  and  sale  of
additional  securities  without the vote of or notice to existing  shareholders,
and  it  is  likely that additional securities will be issued to provide  future
financing  or  in  connection  with acquisitions.  The  issuance  of  additional
securities  could dilute the percentage interests and per share  book  value  of
existing shareholders, including persons purchasing securities in this offering.

Volatility  of  Price  for Common Stock.  The market price  for  shares  of  the
Company's Common Stock may be highly volatile depending on news announcements or
changes  in  general market conditions.  In recent years the  stock  market  has
experienced extreme price and volume fluctuations.

          Risks Related to the Exploration and Development of Minerals
Nature of Mineral Exploration and Development; No Proven Commercially Viable
Reserves Yet Discovered on the Company's Mineral Properties (with the exception
of the San Luis gold mine).  Exploration for minerals is highly speculative and
may involve greater risks than many other businesses.  Many exploration
programs, including those which have been conducted by the Company, do not
result and have not resulted in the discovery of mineralization and any
mineralization discovered may not be of sufficient quantity or quality to be
profitably mined.  The Company's mineral exploration and development activities
are subject to all of the operating hazards and risks normally incident to such

                                       7

<PAGE>
activities, such as encountering unusual or unexpected formations, environmental
pollution,  personal injury and flooding.  All of these factors  may  result  in
losses  in  relation to the amounts spent which are not recoverable.   With  the
exception  of the San Luis gold mine, no commercially viable reserves  have  yet
been discovered on the Company's mineral properties.

Competition  and Scarcity of Mineral Lands.  Many companies and individuals  are
engaged  in  mineral  exploration and development, including large,  established
mining companies with substantial capabilities and long earnings records.  There
is  a  limited  amount of desirable mineral lands available for  claim  staking,
lease  or  other  acquisition in the United States ("US"), Venezuela  and  other
areas  where  the  Company contemplates conducting exploration activities.   The
Company  may  be  at a competitive disadvantage in acquiring mineral  properties
since  it must compete with these individuals and companies, many of which  have
greater financial resources and larger technical staffs than the Company.   From
time  to  time, specific properties or areas which would otherwise be attractive
to  the  Company  for exploration or acquisition are unavailable  due  to  their
previous acquisition by other companies.

Fluctuation in the Price of Minerals.  The market price of minerals is extremely
volatile and beyond the control of the Company.  Gold prices are generally
influenced by basic supply/demand fundamentals.  The market dynamics of
supply/demand can be heavily influenced by economic policy, i.e., central banks
sales/purchases, political unrest, conflicts between nations, and general
perceptions about inflation.  Fluctuating metal prices may have a significant
impact on the Company's results of operations and operating cash flow.
Furthermore, if the price of a mineral should drop dramatically, the value of
the Company's properties which are being explored or developed for that mineral
could also drop dramatically, and the Company might not be able to recover its
investment in those properties.  The decision to put a mine into production, and
the commitment of the funds necessary for that purpose, must be made long before
the first revenues from production will be received.  During the last five
years, the average annual market price of gold has fluctuated between $344 per
ounce and $384 per ounce.  Price fluctuations between the time that such a
decision is made and the commencement of production can change completely the
economics of the mine.  Although it is possible to protect against price
fluctuations by hedging in certain circumstances, the volatility of mineral
prices represents a substantial risk in the mining industry generally which no
amount  of  planning or technical expertise can eliminate.  The Company  is  not
involved in, nor does it expect to enter into any hedging activities

Environmental Controls.  Compliance with environmental quality requirements  and
reclamation  laws imposed by federal, state, provincial, and local  governmental
authorities  may necessitate significant capital outlays, may materially  affect
the  economics of a given property, or may cause material changes or  delays  in
the  Company's  intended  activities.  New or different environmental  standards
imposed  by  any governmental authority in the future may adversely  affect  the
Company's activities.

Uncertainty of Title.  Several of the Company's mining properties which  are  in
the  United States are unpatented mining claims to which the Company,  or  those
under  which  the Company holds its rights, has only possessory title.   Because
title  to unpatented mining claims is subject to inherent uncertainties,  it  is
difficult  to  determine  conclusively  ownership  of  such  claims.   Since   a
substantial  portion of all mineral exploration, development and mining  in  the
United  States  now  occurs  on unpatented mining claims,  this  uncertainty  is
inherent  in the mining industry.  In addition, in order to retain title  to  an
unpatented  mining  claim, a claim holder must have met annual  assessment  work
requirements  ($100 per claim) through September 1, 1992 and must have  complied
with  stringent  state  and  federal regulations pertaining  to  the  filing  of
assessment  work affidavits.  Moreover, after September 1, 1992,  the  right  to
locate  or maintain a claim generally is conditional upon payment to the  United
States  of  a  rental  fee of $100 per claim per year for each  assessment  year
instead of performing assessment work.  State law may, in some instances,  still
require performance of assessment work.

The  present  status  of  the Company's properties as unpatented  mining  claims
located  on public lands of the U.S. allows the claimant the exclusive right  to
mine  and  remove  valuable  minerals, such as  precious  and  base  metals  and
industrial  minerals, found therein, and also to use the  surface  of  the  land
solely for

                                        8

<PAGE>

purposes  related to mining and processing the mineral-bearing  ores.   However,
legal  ownership  of  the  land  remains with the  U.S.   Accordingly,  with  an
unpatented claim, the U.S. retains many of the incidents of ownership  of  land,
the  U.S. regulates use of the surface, and the Company remains at risk that the
claims may be forfeited either to the U.S. or to rival private claimants due  to
failure to comply with statutory requirements as to locations and maintenance of
the claims.  If there exists a valuable deposit of locatable minerals (which  is
the  requirement for the unpatented claim to be valid in the first  place),  and
provided  certain  levels of work and improvements have  been  performed  on  an
unpatented  mining  claim, the Mining Law of 1872 authorizes claimants  to  then
seek  to  purchase  the full title to the claim, thereby causing  the  claim  to
become  the  private property of the claimant.  Such full ownership expands  the
claimant's  permissible uses of the property (to any use authorized for  private
property)  and  eliminates  the need to comply with  maintenance  and  reporting
requirements necessary to protect rights in an unpatented claim.

Proposed  Legislation  Affecting  the Mining Industry.   For  the  last  several
Congressional  sessions,  bills  have been repeatedly  introduced  in  the  U.S.
Congress  which would supplant or radically alter the provisions of  the  Mining
Law of 1872.  As of March 31, 1997, no such bills have passed, although a number
of  differing and sometimes conflicting bills are now pending.  If enacted, such
legislation  could substantially increase the cost of holding unpatented  mining
claims and could impair the ability of companies to develop mineral resources on
unpatented mining claims.  Under the terms of certain proposed legislation,  the
ability  of  companies to obtain a patent on unpatented mining claims  would  be
nullified  or substantially impaired.  Moreover, certain forms of such  proposed
legislation  contain  provisions for the payment of  royalties  to  the  federal
government  in respect of production from unpatented mining claims, which  could
adversely  affect the potential for development of such claims and the economics
of  operating existing mines on federal unpatented mining claims.  The Company's
financial performance could therefore be affected adversely by passage  of  such
legislation.   It  is  impossible to predict at this point what  any  legislated
royalties  might  be,  but  a  potential three to four  percent  gross  royalty,
assuming a gold price of $400 per ounce, would have an approximated $12  to  $16
per ounce impact on the Company's costs of any production from unpatented mining
claims.

Uncertainty  of  Funding for Exploration.  The Company has funded  much  of  its
exploration and acquisition activities through joint venture arrangements, which
minimize the cost of such activities to the Company and allow it to explore  and
acquire  a  greater  number of properties than it would  otherwise  be  able  to
explore  or  acquire on its own.  The Company has also funded a portion  of  its
exploration  activities  without  joint  venture  participation,  resulting   in
increased costs to the Company.  The Company has been successful in raising such
funds for its exploration activities.  Additional funding from existing partners
or  third  parties, however, may be necessary to conduct detailed  and  thorough
evaluations  of,  and to develop certain properties.  The Company's  ability  to
obtain  this financing will depend upon, among other things, the price  of  gold
and  the industry's perception of its future price.  Therefore, availability  of
funding is dependent largely upon factors outside of the Company's control,  and
cannot be accurately predicted.  The Company does not know from what sources  it
will  derive  any  required  funding.  If the  Company  is  not  able  to  raise
additional funds (as to which there can be no assurance), it will not be able to
fund certain exploration activities on its own.

Uncertainty  of Development and Operating Property Economics and Ore  Grades  at
Development  Properties.  Decisions as to whether any of the mineral development
properties  which the Company now holds or which it may acquire  in  the  future
contain  commercially  minable  deposits, and  whether  such  properties  should
therefore  be  sold  or  brought into production, depend  upon  the  results  of
exploration programs and/or feasibility analyses and the recommendations of duly
qualified  engineers  or geologists.  Such decisions involve  consideration  and
evaluation  of several significant factors, including, but not limited  to,  the
(a)  costs  of  bringing a property into production, including  exploration  and
development work, preparation of production feasibility studies and construction
of  production facilities, (b) availability and costs of financing, (c)  ongoing
costs  of production, (d) market prices for the mineral to be produced, and  (e)
the  amount  and grades of reserves or mineralized material.  There  can  be  no
assurance  that  any of the development properties now held by the  Company,  or
which may be acquired by the Company,

                                       9

<PAGE>

contains a commercially minable mineral deposit, and therefore no assurance that
the  Company  will  ever  generate a positive cash flow  from  the  sale  of  or
production operations on such properties. In addition, once a property  is  sold
with  a  retained royalty or placed into production, risks still exist that  the
amount  and  grade  of its reserves will not actually be as predicted.   To  the
extent  that lower amounts and/or grades of reserves are experienced, costs  per
unit  produced and profitability can be adversely affected.  Depending upon  the
extent  of such an effect in any of the Company's properties, the Company  could
incur a writedown on its investment in any such property.

Termination  of Mining at the San Luis Gold Mine.  Royalty income from  the  San
Luis  gold  mine has been the only significant source of income for the  Company
for  the last five years.  The mine is leased to and operated by Battle Mountain
Gold Co. ("BMGC").  As reported to the Company by BMGC, mining was completed  at
the end of October, 1996.  The Company's royalty income from the property ceased
shortly after that time.

     Risks Related to the Production and Sale of Purified Phosphate Products
                                        
Uncertain  Commercial  Viability  of Solvent Extraction  Process.   The  solvent
extraction  process  developed by the Company for  the  production  of  purified
phosphoric acid ("PPA") has not been proven on a commercial basis at the Calgary
plant.  Although the Company has performed numerous bench-scale and pilot  plant
test  of  the  process, there can be no assurances that the process  will  yield
satisfactory results when employed on a commercial scale.

Limited Experience in Marketing Industrial Chemicals and Lack of Long-term Sales
Contracts.  The growth and profitability of operations at the Company's  solvent
extraction  facility in Calgary will be dependent upon, among other things,  the
sale of purified phosphate products to chemical distributors and customers.  The
Company  has  limited experience in marketing industrial chemicals and  will  be
relying on consultants and others to initiate and maintain sales contacts.   PPA
is  not typically sold under long-term contracts, and the Company does not  have
any  long-term commitments to purchase its planned products.  There  can  be  no
assurances that the Company will be successful in its sales efforts.

Supply  of  Raw  Materials. The growth and profitability of  operations  at  the
Company's  solvent extraction facility in Calgary will be dependent upon,  among
other things, the availability of sufficient raw materials at reasonable prices.
The  Company  has negotiated renewable annual supply contracts with Agrium  U.S.
Inc.  ("Agrium")  and Farmland Industries ("Farmland") to supply  the  estimated
requirement  of  superphosphoric acid ("SPA").  The contracts  with  Agrium  and
Farmland  both contain provisions that allow extension of the contracts  in  the
future  or  termination upon a several month written notice.  There  can  be  no
assurances that the Company will be able to extend these contracts in the future
and obtain sufficient quantities of SPA at reasonable prices.

Ability to Expand Geographically. The growth and profitability of operations  at
the  Company's  solvent extraction facility in Calgary will be  dependent  upon,
among other things, the ability to become the predominate supplier of PPA in the
geographic region surrounding Calgary and on the US West Coast, and to  sell  on
an  increasing basis to the Minneapolis/Chicago area.  There can be no assurance
that  the  Company's efforts to expand sales can be accomplished on a profitable
basis.

Competition.  The Company's purified phosphate products will be sold in  markets
that  are highly competitive.  The principal competitive factors include product
quality,  price and distribution capabilities.  There can be no assurances  that
the  Company  will  be able to compete successfully against current  and  future
competitors  based  on  these factors.  The Company will  compete  with  several
domestic  and  international producers, many of whom have substantially  greater
financial,  production, distribution and marketing resources than  the  Company.
Increased competition could result in price reductions, reduced margins and loss
of  market  share,  all  of which could have a material adverse  affect  on  the
Company's business, financial condition and results of operations.

Effect  of Potential Lack of Demand for ADA's Services.  If there is no  demand,
or  the  demand  is  less  than  projected, for  ADA's  services  for  flue  gas
conditioning,  the  Company will not recognize the synergies expected  from  its
acquisition,  because  ADA will not be able to utilize  the  Company's  purified
phosphate products.

PLAN OF DISTRIBUTION

This  Prospectus  relates to the public offer and sale by  certain  shareholders
(the "Selling Shareholders") of an aggregate of 3,036,354 shares of Common Stock
of  the  Company  issuable  on conversion of the Debentures  for  a  maximum  of
2,463,334  shares  of  Common Stock, upon the exercise of  options  to  purchase
339,000 shares of Common Stock and 234,020 shares of Common Stock currently held
by Selling Shareholders.

The  Common  Stock to be sold by the Selling Shareholders  may be sold  by  them
from   time  to  time  directly  to  purchasers.   Alternatively,  the   Selling
Shareholders may, from time to time, offer the Common Stock through  dealers  or
brokers,  who receive compensation in the form of commissions from  the  Selling
Shareholders  and/or the purchasers of the Common Stock for  whom  they  act  as
agents.   As of the date hereof, no Selling Shareholder has advised the  Company
that  it  has  entered into any agreement or understanding with  any  dealer  or
broker for the offer or sale of the Common Stock.  The Selling Shareholders  may
enter  into  such  agreements  or understandings in  the  future.   The  Selling
Shareholders  may  also  offer some or all of the Common  Stock  through  market
transactions on Nasdaq, on which the Company's Common Stock is traded.  Sales of
the Common Stock through brokers may be made by any method of trading authorized
by Nasdaq, including block trading in negotiated transactions.  Without limiting
the  foregoing, such brokers may act as dealers purchasing any  or  all  of  the
Common Stock covered by this Prospectus.  Sales of Common Stock are, in general,
expected  to  be made at the market price prevailing at the time  of  each  such
sale;  however,  prices in negotiated transactions may differ considerably.   No
Selling  Shareholder  has  advised the Company that it  anticipates  paying  any
consideration,   other  than  usual  and  customary  broker's  commissions,   in
connection with sales of the Common Stock.  The Selling Shareholders are  acting
independently  of the Company in making decisions with respect  to  the  timing,
manner and size of each sale.

DESCRIPTION OF COMMON STOCK

The  authorized  capital stock of the Company consists of 25,000,000  shares  of
Common  Stock,  $0.01  par value per share.  All of the issued  and  outstanding
stock  of the Company is fully paid and nonassessable.  Holders of Common  Stock
are  entitled  to  receive  dividends, when and if  declared  by  the  Board  of
Directors, out of funds legally available therefore and to share ratably in  the
net assets of the Company upon liquidation.  Holders of Common Stock do not have
preemptive  rights  to  subscribe  for additional  shares,  nor  are  there  any
redemption  or sinking fund provisions associated with the Common Stock.   There
are   currently   8,620,051  shares  of  Common  Stock  outstanding   owned   by
approximately 3,000 persons and/or entities.

Holders  of  Common  Stock are entitled to one vote per  share  on  all  matters
requiring  a  vote of the shareholders.  Since the Common Stock  does  not  have
cumulative  voting  rights in electing directors, the holders  of  more  than  a
majority  of  the outstanding shares of Common Stock voting for the election  of
directors can elect all of the directors whose terms expire that year,  if  they
so choose.

Item 15.  Indemnification of Directors and Officers.

      Article  7-109  of  the Colorado Business Corporation Act  authorizes  the
indemnification of directors and officers against liability incurred  by  reason
of being a director or officer and against expenses (including attorney's fees),
judgments,  fines  and  amounts paid in settlement and  reasonably  incurred  in
connection with any action seeking to establish such liability, in the  case  of
third-party  claims, if the officer or director acted in good  faith  and  in  a
manner  he reasonably believed to be in or not opposed to the best interests  of
the  corporation,  and  in  the case of actions  by  or  in  the  right  of  the
corporation, if the officer or director acted in good faith and in a  manner  he
reasonably  believed  to  be  in or not opposed to the  best  interests  of  the
corporation and if such officer or director shall not have been adjudged  liable
to  the  corporation, unless a court otherwise determines.   Indemnification  is
also  authorized  with  respect to any criminal action or proceeding  where  the
officer  or  director also had no reasonable cause to believe  his  conduct  was
unlawful.

      The  above discussion of the Colorado Business Corporation Act is  only  a
summary and is qualified in its entirety by the full text of the foregoing.

Article VIII of the Registrant's Bylaws provides as follows:

     Each past, present and future director and officer of the corporation shall
be   indemnified  by  the  corporation  against  all  expenses,  penalties,  and
liabilities,  including attorneys' fees, reasonably incurred by or imposed  upon
him  in  connection  with  any actual or threatened  claim,  demand,  action  or
proceeding,  whether  civil or criminal, or in connection  with  any  settlement
thereof, to which he may be made a party, or in which he may become involved, by
reason  of  his  being or having been a director or officer of the  corporation,
whether  or not he is a director or officer at the time such expenses, penalties
or  liabilities are incurred, except in cases where he shall be finally adjudged
in  such  action  or  proceeding  to be liable for  willful  misconduct  in  the
performance  of  his  duties  as  such  director  or  officer.   The  right   of
indemnification herein provided shall be in addition to, and not  exclusive  of,
all other rights to which such director or officer may be entitled and the right
of  indemnification herein provided shall inure to the benefit of  the  personal
representatives of deceased directors and officers.

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 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.
      (2)   That,  for  the  purposes of determining  any  liability  under  the
Securities Act of 1933 (the "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.
     (4)  That, for purposes of determining liability under the Act, each filing
of  the registrant's annual report pursuant to section 13(a) or section 15(d) of
the  Securities Exchange Act of 1934 (and where applicable, each  filing  of  an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act  of 1934) 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.
     (5)  That, insofar as indemnification for liabilities arising under the 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 Securities and Exchange Commission
such  indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of
such issue.
