                                    ------ 

   Commodore Separation Technologies, Inc., a Delaware corporation (the 
"Company"), hereby offers (the "Offering") two separate units of securities 
(together, the "Units") consisting of (a) 1,500,000 shares of 10% Senior 
Convertible Redeemable Preferred Stock, par value $.001 per share and 
liquidation preference of $10.00 per share (the "Convertible Preferred 
Stock"), and 1,500,000 Redeemable Common Stock Purchase Warrants (the 
"Warrants"), each unit (the "Preferred Units") consisting of one share of 
Convertible Preferred Stock and one Warrant, and (b) 1,500,000 shares of 
Common Stock, par value $.001 per share (the "Common Stock"), and 1,500,000 
Warrants, each unit (the "Common Units") consisting of one share of Common 
Stock and one Warrant. The Convertible Preferred Stock, Common Stock and 
Warrants included in the Units are sometimes collectively referred to as the 
"Securities." Until completion of the Offering, the Securities included in 
the Preferred Units and Common Units may only be purchased together in their 
respective Units, but each of the Securities will trade separately 
immediately after the Offering. The Convertible Preferred Stock is 
convertible into Common Stock at any time prior to redemption at the rate of 
1.33 shares of Common Stock for each share of Convertible Preferred Stock, an 
effective conversion price of $7.50 per share or 125% of the initial public 
offering price per share of Common Stock (subject to adjustment under certain 
circumstances). Commencing March   , 2000, the Convertible Preferred Stock is 
subject to redemption by the Company, in whole but not in part, at $10.00 per 
share, plus accumulated and unpaid dividends on 30 days' prior written 
notice, provided that the closing bid price of the Common Stock for at least 
20 consecutive trading days ending not more than 10 trading days prior to the 
date of the notice of redemption equals or exceeds $11.25 per share, or, 
after March  , 2001, at the cash redemption prices set forth herein, plus 
accumulated and unpaid dividends. Cumulative dividends on the Convertible 
Preferred Stock at the rate of $1.00 per share per annum are payable 
quarterly, out of funds legally available therefor, on the last business day 
of March, June, September and December of each year, commencing June 30, 
1997. Each Warrant included in the Preferred Units and Common Units contains 
identical terms and entitles the registered holder thereof to purchase one 
share of Common Stock at an initial exercise price of $8.40 per share, 
subject to adjustment, at any time commencing one year after the date of this 
Prospectus until five years after the date of this Prospectus. Commencing 18 
months after the date of this Prospectus, the Warrants are subject to 
redemption by the Company, in whole but not in part, at $.10 per Warrant on 
30 days' prior written notice provided that the average closing sale price of 
the Common Stock equals or exceeds $18.00 per share (subject to adjustment 
under certain circumstances) 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. See "Description of Securities." 
    

   Prior to this Offering, there has been no public market for the Securities 
and there can be no assurance that such a market will develop after the 
completion of this Offering or, if developed, that it will be sustained. It 
is currently anticipated that the initial public offering prices of the 
Preferred Units and the Common Units will be $10.10 per unit and $6.10 per 
unit, respectively, with the Convertible Preferred Stock, Common Stock and 
Warrants priced at $10.00 per share, $6.00 per share and $.10 per Warrant, 
respectively. For information regarding the factors considered in determining 
the initial public offering prices of the Securities and the terms of the 
Convertible Preferred Stock and Warrants, see "Risk Factors" and 
"Underwriting." Application has been made to include the Convertible 
Preferred Stock, the Common Stock and the Warrants on the Nasdaq Small-Cap 
Market ("Nasdaq") under the symbols "CXOTP," "CXOT" and "CXOTW," 
respectively. 

  THE SECURITIES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK AND IMMEDIATE 
 SUBSTANTIAL DILUTION. SEE "RISK FACTORS" BEGINNING ON PAGE 11 AND 
                                 "DILUTION."

Compensation -- Stock Options" and "Underwriting." The Company is a 
development stage company which has had no commercial operations to date. 

                                 THE COMPANY 

   Commodore Separation Technologies, Inc. (the "Company") has developed and 
intends to commercialize its membrane separation and recovery system called 
CST. Based on the results of more than 100 laboratory and other tests to 
date, the Company believes that CST can separate and recover chrome, 
chromium, cadmium, silver, mercury, platinum, lead, zinc, nickel, 
trichlorethylene, polychlorinated biphenyls, methylene chloride, amino acids, 
antibiotics, radionuclides, and other organic and inorganic targeted 
substances from liquid or gaseous feedstreams. CST utilizes a process whereby 
a contaminated liquid or gaseous feedstream is introduced into a fibrous 
membrane unit or module containing a proprietary chemical solution, the 
composition of which is customized depending on the types and concentrations 
of compounds in the feedstream. As the feedstream enters the membrane, the 
targeted substance reacts with CST's proprietary chemical solution and is 
extracted through the membrane into a strip solution where it is then stored. 
The remaining feedstream is either recycled or discharged as non-toxic 
effluent. In some instances, additional treatment may be required prior to 
disposal. 

   CST is distinguishable from other existing forms of membrane filtration 
technology in that it: 

   o  requires low initial capital costs and low operating costs; 

   o  has the capability of treating a wide variety of elements and compounds 
      in a wide variety of industrial settings at great speed and with a high 
      degree of effectiveness, regardless of contaminant concentrations, 
      volume requirements and other variables; 

   o  is environmentally safe, in most instances producing no sludges or 
      other harmful by-products which would require additional post-treatment 
      prior to disposal; 

   o  can selectively extract target substances, while extracting 
      substantially fewer unwanted substances; 

   o  can typically operate on-site and in less than 40 square feet of space 
      for the entire system; 

   o  can extract metals, organic chemicals and other elements and compounds 
      in degrees of concentration and purity which permit their reuse; and 

   o  has the capability, in a single process application, of selectively 
      extracting multiple elements or compounds from a mixed process stream. 

                                      5

   In August 1996, the Company completed an on-site demonstration of CST for 
the decontamination of chromium-contaminated groundwater at the Port of 
Baltimore, Maryland. During this demonstration, a CST unit, in a single 
feedstream pass-through, reduced the contamination level of chromium from 
more than 400 parts per million (ppm) to less than one ppm. The results of 
this test were verified by Artesian Laboratories, Inc., an independent 
testing laboratory. The Company has since completed additional on-site 
demonstrations of CST at the Port of Baltimore with similar results. Due to 
the success of such demonstrations, in February 1997 the State of Maryland 
informed the Company that it will recommend including the CST process as an 
eligible technology in the bid specifications to remediate the groundwater at 
the Port of Baltimore. Based on management studies and discussions with 
metals industry executives, the Company believes that CST represents a 
significant technological advancement in the area of environmental 
remediation as the only technology capable of on-site chromium removal and 
recovery that enables effluent discharge without additional treatment. 
    

   In September 1996, the Company installed a commercial scale CST unit at a 
Columbus, Ohio metal plating company. DLZ Laboratories, Inc., an independent 
testing laboratory, verified that the CST unit processed the initial batch of 
process effluent stream and reduced nickel and zinc contamination from 900 
ppm to 2 ppm in one hour. The Company has continued to operate this CST unit 
to process nickel and zinc effluent streams containing concentrations of 200 
to 400 ppm, and the unit has consistently reduced the contaminant levels to 1 
to 5 ppm. The decontaminated process effluent stream is being recycled into 
the plating line rinse tanks, saving the plating company its normal 
consumption of make-up water at a rate of five gallons per minute. The 
recovered nickel and zinc solution is currently being analyzed by the plating 
company for reuse in its plating operations. 

   In January 1997, the Company entered into a license agreement with 
Lockheed Martin Energy Research Corporation ("Lockheed Martin"), manager of 
the Oak Ridge National Laboratory, a U.S. Department of Energy national 
laboratory ("Oak Ridge"). Under the terms of the agreement, the Company 
received the exclusive worldwide license, subject to a government use 
license, to use and develop the technology related to the separation of the 
radionuclides technetium and rhenium from mixed wastes containing radioactive 
materials. Based on tests conducted at Oak Ridge since May 1994, the Company 
believes that this technology is capable of selectively extracting and 
recovering technetium, rhenium and other radioactive isotopes as a 
concentrated aqueous solution which can be reused in various scientific 
applications or disposed of by government-approved techniques including 
long-term storage. The Company believes that this technology can be used to 
remediate nuclear waste tanks stored at the U.S. Department of Energy's 
atomic energy plants in Rocky Flats, Colorado, Idaho Falls, Idaho, Paducah, 
Kentucky, Weldon Springs, Missouri, Frenchman Flat, Nevada, Los Alamos, New 
Mexico, Aiken, South Carolina, Oak Ridge, Tennessee, Pantex, Texas and 
Hanford, Washington, and intends to pursue such opportunities. According to 
Department of Energy sources, there are approximately 100 million gallons of 
mixed radioactive and hazardous chemical waste stored at these plants. 

   The Company will market its technology to industries engaged in 
metallurgical processing, metal plating and mining, as well as companies 
producing organic chemicals and biochemicals and those engaged in gas 
separation. The Company is also targeting governmental agencies that have 
sites which require remediation, and has already completed an on-site 
demonstration at the Port of Baltimore. 

   The Company intends to pursue collaborative joint working and marketing 
arrangements with, or acquisitions of or investments in, companies that have 
a presence in target markets and those that focus on obtaining environmental 
remediation projects, including clean-up of harbors, groundwater and nuclear 
waste sites. Although the Company has entered into memorandums of 
understanding for proposed working arrangements with Teledyne Brown 
Engineering, Inc., a subsidiary of Allegheny Teledyne Inc. ("Teledyne 
Brown"), and Sverdrup Environmental, Inc. ("Sverdrup"), and is bidding on 
certain projects, there can be no assurance that any of these activities will 
result in definitive collaborative agreements or project awards. Even if 
project contracts are awarded to the Company, CST has never been utilized on 
a large-scale basis, and there is no assurance that this technology will 
perform successfully on a large-scale commercial basis, or that it will be 
profitable to the Company. There can also be no assurance that this 
technology will not be superseded by other competing technologies.

                                 RISK FACTORS 

   An investment in the Securities offered hereby involves a high degree of 
risk and should be made only by investors who can afford the loss of their 
entire investment. Prospective investors should carefully review and consider 
the risk factors described below and the other information in this Prospectus 
before purchasing the Securities. 

NO OPERATING HISTORY; ACCUMULATED AND WORKING CAPITAL DEFICITS; INITIAL 
COMMERCIALIZATION STAGE; GOING CONCERN DISCLOSURE IN INDEPENDENT AUDITORS' 
REPORT 

   
   The Company was organized in November 1995 and has had no commercial 
operations to date. Since its inception, the Company has been engaged 
principally in organizational activities, including developing a strategic 
operating plan, entering into contracts, hiring personnel, developing test 
modules and installing and operating modules on a limited basis for 
demonstration or test purposes. The Company is considered a development stage 
company for accounting purposes because it has not generated any material 
revenues to date. Accordingly, the Company has no relevant operating history 
upon which an evaluation of its performance and prospects can be made. The 
Company is subject to all of the business risks associated with a new 
enterprise, including, but not limited to, risks of unforeseen capital 
requirements, failure of market acceptance, failure to establish business 
relationships, and competitive disadvantages as against larger and more 
established companies. The report of the independent auditors with respect to 
the Company's financial statements included in this Prospectus includes a 
"going concern" qualification, indicating that the Company's significant 
operating losses and deficits in working capital and stockholders' equity 
raise substantial doubt about its ability to continue as a going concern. See 
Financial Statements. 

   The Company has generated nominal revenues to date, and will not generate 
any material revenues until after the Company successfully completes the 
installation of modules in a significant number of industrial companies, of 
which no assurance can be given. As of December 31, 1996 and June 30, 1996, 
the Company had working capital deficits of $(134,677) and $(81,630), 
respectively, and stockholders' equity and deficit of $76,460 and $(60,836), 
respectively. During the period from November 15, 1995 (date of inception) to 
December 31, 1996, the Company has incurred operating losses of $(914,740), 
and anticipates that it may continue to incur significant operating losses 
for the foreseeable future. There can be no assurance as to whether or when 
the Company will generate material revenues or achieve profitable operations. 
See "Management's Discussion and Analysis of Financial Condition and Results 
of Operations," "Business" and Financial Statements. 
    

INADEQUATE DIVIDEND COVERAGE 

   The annual dividend requirement on the Convertible Preferred Stock is 
$1,500,000 ($1,725,000 if the Over-allotment Option is exercised in full). 
The future earnings of the Company, if any, will not initially be adequate to 
pay the dividends on the Convertible Preferred Stock, and, although the 
Company will pay quarterly dividends out of available capital surplus, there 
can be no assurance that the Company will maintain sufficient capital surplus 
or that future earnings, if any, will be adequate to pay the dividends on the 
Convertible Preferred Stock. Under the Delaware General Corporation Law, 
dividends may be paid only out of legally available funds. Failure to pay any 
quarterly dividend will result in a reduction in the conversion price and 
failure to pay a total of four consecutive quarterly dividends will entitle 
the holders of the Convertible Preferred Stock, voting separately as a class, 
to elect one director. In addition, no dividends or distributions may be 
declared, paid or made if the Company is or would be rendered insolvent by 
virtue of such dividend or distribution. See "Dividend Policy" and 
"Description of Securities -- Convertible Preferred Stock." 

UNPROVEN ON LARGE-SCALE COMMERCIAL BASIS 

   CST has never been utilized on a large-scale commercial basis. All of the 
tests conducted to date by the Company with respect to CST have been 
performed on limited quantities of process streams, and there can be no 
assurance that the same or similar results could be obtained on a large-scale 
commercial basis or on any specific project. The Company has never utilized 
CST under the conditions and in the volumes that will be required to be 
profitable and cannot predict all of the difficulties that may arise. In 
addition, most of the results of more than 100 laboratory and other tests 
conducted by the Company have not been verified by an independent testing 
laboratory. Thus, it is possible that the Company's CST unit may require 
further research, development, 

                                      11 
<PAGE>

design and testing, as well as regulatory clearances, prior to larger-scale 
commercialization. Additionally, the Company's ability to operate its 
business successfully will depend on a variety of factors, many of which are 
outside the Company's control, including competition, cost and availability 
of strategic components, changes in governmental initiatives and 
requirements, changes in regulatory requirements, and the costs associated 
with equipment repair and maintenance. See "Business." 

   
DEPENDENCE ON STRATEGIC COMPONENTS FROM SUPPLIERS; LIMITED MANUFACTURING 
OPERATIONS 
    

   The Company currently has a limited number of sources of supply for some 
CST components, such as fibers and membrane casings. Business disruptions or 
financial difficulties of suppliers, or raw material shortages or other 
causes beyond the Company's control, could adversely affect the Company by 
increasing the cost of goods sold or reducing the availability of such 
components. In its development to date, the Company has been able to obtain 
adequate supplies of these strategic components. However, as it commences 
commercial activities, the Company expects to experience a rapid and 
substantial increase in its requirements for these components. If the Company 
were unable to obtain a sufficient supply of required components, the Company 
could experience significant delays in the manufacture of CST equipment, 
which could result in the loss of orders and customers, and could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. Although the Company plans to use a portion of the net 
proceeds of this Offering to build its own manufacturing plant for these 
strategic components, there can be no assurance as to whether or when such 
plant will be completed, that it will be able to manufacture components more 
inexpensively than the cost of current sources of supply or that, prior to 
the completion of such plant, the Company will not require alternative 
sources of such components or experience delays in obtaining adequate CST 
components. The occurrence of any of such events would have a material 
adverse effect on the Company's business, financial condition and results of 
operations. In addition, if the cost of raw materials or finished components 
were to increase, there can be no assurance that the Company would be able to 
pass such increases to its customers. See "Management's Discussion and 
Analysis of Financial Condition and Results of Operations -- Dependence on 
Suppliers" and "Business -- Proposed Manufacturing Operations." 

UNCERTAINTY OF MARKET ACCEPTANCE 

   Many prospective users of CST have committed substantial resources to 
other forms of process stream treatments or technologies. The Company's 
growth and future financial performance will depend on its ability to 
demonstrate to prospective users the technical and economic advantages of CST 
over these alternatives. There can be no assurance that the Company will be 
successful in this effort. Furthermore, it is possible that competing 
alternatives may be perceived to have, or may actually have, certain 
advantages over CST for certain industries or applications. See "Business." 

RISK OF INTERNATIONAL OPERATIONS 

   
   The Company intends to market CST in international markets, including both 
industrialized and developing countries. International operations entail 
various risks, including political instability, economic instability and 
recessions, exposure to currency fluctuations, difficulties of administering 
foreign operations generally, and obligations to comply with a wide variety 
of foreign import and United States export laws, tariffs and other regulatory 
requirements. The Company's competitiveness in overseas markets may be 
negatively impacted when there is a significant increase in the value of the 
dollar against the currencies of the other countries in which the Company 
does business. In addition, the laws of certain foreign countries may not 
protect the Company's proprietary rights to the same extent as the laws of 
the United States and there may be no legal recourse for the Company in 
certain adverse circumstances as United States companies may not have 
jurisdiction in other countries. See "Business -- Environmental Matters," "-- 
Intellectual Property" and "-- Competition." 

UNSPECIFIED ACQUISITION-RELATED RISKS 

   As part of its growth strategy, the Company will seek to acquire or invest 
in complementary (including competitive) businesses, products or 
technologies. The Company has allocated $1,250,000 (or 5.9%) of the net 
proceeds of this Offering for financing such possible acquisitions or 
investments. See "Use of Proceeds." The process of integrating such acquired 
assets into the Company's operations may result in unforeseen operating 
difficulties and expenditures and may absorb significant management attention 
that would otherwise be available for the ongoing development of the 
Company's business. There can be no assurance that the anticipated benefits 
of any acquisitions will be realized. In addition, future acquisitions by the 
Company could result in potentially 
    

                                      12 
<PAGE>

   
dilutive issuances of equity securities, the incurrence of debt and 
contingent liabilities and amortization expenses related to goodwill and 
other intangible assets, any of which could materially adversely affect the 
Company's operating results and financial position. Acquisitions also involve 
other risks, including entering markets in which the Company has no or 
limited prior experience. The Company currently has no commitments or 
agreements with respect to any possible acquisitions or investments. 

EFFECT OF ACQUISITIONS ON PERSONNEL 

   As noted above, future acquisitions by the Company could also result in 
the possibility of changing current Company management with no opportunity 
for the Company's stockholders to evaluate new key personnel. 
    

UNPREDICTABILITY OF PATENT PROTECTION AND PROPRIETARY TECHNOLOGY 

   The Company currently has one United States utility patent application 
pending and two United States provisional patent applications pending and may 
in the future file foreign patent applications. The Company's success 
depends, in part, on its ability to obtain patents, maintain trade secrecy, 
and operate without infringing on the proprietary rights of third parties. 
There can be no assurance that the patents of others will not have an adverse 
effect on the Company's ability to conduct its business, that any of the 
Company's pending patent applications will be approved, that the Company will 
develop additional proprietary technology which is patentable or that any 
patents issued to the Company will provide the Company with competitive 
advantages or will not be challenged by third parties. Furthermore, there can 
be no assurance that others will not independently develop similar or 
superior technologies, duplicate elements of CST, or design around CST. 

   The Company's liquid membrane technology patent applications are based on 
the selective combination of different known solvents, supports, diluents, 
carriers and other components to separate a variety of metals, chemicals and 
other targeted substances. While the Company believes that its technology 
covers all separation applications, third parties may have developed, or may 
subsequently assert claims to, certain of these solvents, supports, diluents, 
carriers or other components for one or more specific applications. In such 
event, the Company may need to acquire licenses to, or to contest the 
validity of, issued or pending patents or claims of third parties. There can 
be no assurance that any license acquired under such patents would be made 
available to the Company on acceptable terms, if at all, or that the Company 
would prevail in any such contest. In addition, the Company could incur 
substantial costs in defending itself in suits brought against the Company 
for alleged infringement of another party's patents or in defending the 
validity or enforceability of the Company's patents, or in bringing patent 
infringement suits against other parties based on the Company's patents. 

   In addition to patent protection, the Company also relies on trade 
secrets, proprietary know-how and technology which it seeks to protect, in 
part, by confidentiality agreements with its prospective working partners and 
collaborators, employees and consultants. There can be no assurance that 
these agreements will not be breached, that the Company will have adequate 
remedies for any breach, or that the Company's trade secrets and proprietary 
know-how will not otherwise become known or be independently discovered by 
others. See "Business -- Intellectual Property." 

ROYALTY OBLIGATIONS 

   Pursuant to an assignment of technology agreement between the Company and 
Srinivas Kilambi, Ph.D., the Company's Vice President-Technology, the Company 
agreed to pay Dr. Kilambi a royalty through December 3, 2002 equal to 2% of 
the Company's revenues actually received and attributed to the commercial 
application of the technology acquired from Dr. Kilambi, except for 
applications related to the radionuclides technetium and rhenium, for which 
Dr. Kilambi is entitled to receive a royalty of .66% of net sales (less 
allowances for returns, discounts, commissions, freight and excise or other 
taxes). Pursuant to the Company's license agreement with Lockheed Martin, the 
Company made an initial cash payment of $50,000 upon the execution of the 
agreement and is obligated to pay, commencing in the third year of the 
agreement, a royalty to Lockheed Martin of 2% of net sales (less allowances 
for returns, discounts, commissions, freight, and excise or other taxes) up 
to total net sales of $4,000,000 and 1% of net sales thereafter. In addition, 
the Company has agreed to guarantee Lockheed Martin, commencing in the third 
year of the agreement, an annual minimum royalty of $15,000. See "Business -- 
Commercialization and Marketing Strategy -- Radionuclide/Mixed Waste 
Separation." Payments of such royalties to Dr. Kilambi and Lockheed Martin 
are based on Company revenues and are not related to or contingent upon the 
Company attaining profitability or positive cash flow. As a result, such 
payments will adversely 

                                      13 
<PAGE>

affect operating results and divert cash resources from use in the Company's 
business, and possibly at times when the Company's liquidity and access to 
funding may be limited. See "Management's Discussion and Analysis of 
Financial Condition and Results of Operations -- Liquidity and Capital 
Resources," "Business -- Intellectual Property" and "Certain Relationships 
and Related Transactions -- Organization and Capitalization of the Company." 

   
RISK OF ENVIRONMENTAL LIABILITY; POSSIBLE INADEQUACY OF INSURANCE COVERAGE 
    

   The Company's operations, as well as the use of the specialized technical 
equipment by its customers, are subject to numerous federal, state and local 
regulations relating to the storage, handling and transportation of certain 
regulated materials. Although the Company's role is generally limited to the 
leasing of its specialized technical equipment for use by its customers, 
there is always the risk of the mishandling of such materials or 
technological or equipment failures, which could result in significant claims 
against the Company. Any such claims against the Company could materially 
adversely affect the Company's business, financial condition and results of 
operations. 

   As CST is commercialized, the Company may be required to obtain 
environmental liability insurance in the future in amounts greater than it 
currently maintains. There can be no assurance that such insurance will 
provide coverage against all claims, and claims may be made against the 
Company (even if covered by the Company's insurance policy) for amounts 
substantially in excess of applicable policy limits. Any such event could 
have a material adverse effect on the Company's business, financial condition 
and results of operations. See "Business -- Environmental Matters." 

POTENTIAL NEED FOR ADDITIONAL FINANCING 

   Prior to this Offering, financing for all of the Company's activities had 
been provided in the form of direct equity investments and loans by Commodore 
and Applied. Although the Company anticipates that the net proceeds of this 
Offering will be sufficient to sustain its operations for approximately 24 
months following the date of this Prospectus, the Company's future capital 
requirements could vary significantly and will depend on certain factors, 
many of which are not within the Company's control. These include the ongoing 
development and testing of CST as a remediation and industrial waste 
management technology; the nature and timing of remediation and clean-up 
projects and permits required; and the availability of financing. 

   In the environmental remediation market, the Company may not be able to 
enter into favorable business collaborations and might thus be required to 
bid upon projects for its own account. If such bids were successful, the 
Company would be required to make significant expenditures on personnel and 
capital equipment which would require significant financing in amounts 
substantially in excess of the net proceeds of this Offering. In addition, 
the Company's lack of operational experience and limited capital resources 
could make it difficult, if not highly unlikely, to successfully bid on major 
reclamation or clean-up projects. In such event, the Company's business 
development could be limited to remediation of smaller commercial and 
industrial sites with significantly lower potential for profit. 

   The expansion of the Company's business will require the commitment of 
significant capital resources toward the hiring of technical and operational 
support personnel, the development of a manufacturing and testing facility 
for CST equipment, and the building of equipment to be used both for on-site 
test demonstrations and the remediation of contaminated elements. In the 
event the Company is presented with one or more significant reclamation or 
clean-up projects, individually or in conjunction with collaborative working 
partners, it may require additional capital to take advantage of such 
opportunities. There can be no assurance that such financing will be 
available or, if available, that it will be on favorable terms. If adequate 
financing is not available, the Company may be required to delay, scale back 
or eliminate certain of its development programs, to relinquish rights to 
certain of its technologies, or to license third parties to commercialize 
technologies that the Company would otherwise seek to develop itself. To the 
extent the Company raises additional capital by issuing equity securities, 
investors in this Offering will be diluted. See "Use of Proceeds" and 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations -- Liquidity and Capital Resources." 

   
MANAGEMENT'S BROAD DISCRETION IN APPLICATION OF PROCEEDS 

   Approximately 48.1% of the net proceeds of this Offering has been 
allocated for working capital and general corporate purposes. The Company may 
use a portion of the net proceeds of this Offering allocated for working 
capital and general corporate purposes for loans to Commodore and such 
proceeds may not be avail- 

                                      14 
    
<PAGE>

   
able for other corporate purposes. In addition, approximately 5.9% and 4.7% 
of the net proceeds of this Offering, respectively, has been allocated for 
potential acquisitions and proposed collaborative arrangements for which the 
Company has no binding agreements as of the date of this Prospectus. 
Accordingly, the Company will have broad discretion as to the application of 
a significant portion of the net proceeds of this Offering. See "Use of 
Proceeds." 
    

COMPETITION AND TECHNOLOGICAL ALTERNATIVES 

   The Company anticipates that CST's primary market will be for industrial 
by-products treatment and disposal. The Company has had limited experience in 
marketing CST and has not previously had any employees or personnel whose 
primary responsibilities for the Company consisted of sales or marketing 
functions. Other participants in both the private and public sectors include 
several large domestic and international companies and numerous small 
companies, many of whom have substantially greater financial and other 
resources and more manufacturing, marketing and sales experience than the 
Company. In addition, as membrane separation technology evolves, there exists 
the possibility that CST may be rendered obsolete by one or more competing 
technologies. Any one or more of the Company's competitors, or one or more 
other enterprises not presently known to the Company, may develop 
technologies which are superior to CST or other technologies utilized by the 
Company. To the extent that the Company's competitors are able to offer more 
cost-effective separation technology alternatives, the Company's ability to 
compete could be materially and adversely affected. See "Business." 

NO ASSURANCE OF COLLABORATIVE AGREEMENTS OR PROJECT AWARDS 

   In addition to its direct marketing efforts, the Company proposes to 
pursue opportunities in the environmental remediation market through 
collaborative joint working arrangements with companies that have a 
significant presence in well-established industries or markets, and that can 
introduce CST as an enabling technology to industry participants. However, 
neither the Company nor any of its prospective collaborative joint working 
partners have been awarded any project contracts. There can be no assurance 
that the Company will enter into any definitive joint project arrangements 
with its prospective working partners or others, or that any such definitive 
arrangements will be on terms and conditions that will enable the Company to 
generate profits. Furthermore, even if the Company is successful in obtaining 
one or more project awards, such projects may be curtailed or eliminated, or 
other problems may arise, which could materially adversely affect the 
Company's business, financial condition and results of operations. 

DEPENDENCE ON KEY MANAGEMENT AND OTHER PERSONNEL 

   
   The Company is dependent on the efforts of its senior management and 
scientific staff, including Edwin L. Harper, Ph.D., Chairman of the Board and 
Chief Executive Officer, Kenneth J. Houle, President and Chief Operating 
Officer, James M. DeAngelis, Senior Vice President, Srinivas Kilambi, Ph.D., 
Vice President -- Technology, Michael D. Kiehnau, Vice President -- 
Operations and Andrew P. Oddi, Vice President -- Finance. Messrs. Houle, 
DeAngelis, Kilambi and Kiehnau have employment agreements with the Company. 
Dr. Harper has an employment agreement with Commodore which requires him to 
serve from time to time in senior executive positions with one or more of 
Commodore's subsidiaries, including the Company. The proceeds of key man life 
insurance policies on the lives of certain of such individuals may not be 
adequate to compensate the Company for the loss of any of such individuals. 
The loss of the services of any one or more of such persons may have a 
material adverse effect on the Company. See "Executive Compensation -- 
Employment Agreements." Alan R. Burkart, who had served as the Company's 
President and Chief Executive Officer since August 1996, resigned from such 
positions in December 1996 for health reasons. Although Mr. Burkart had 
previously been listed as a key employee, the loss of whom would materially 
adversely affect the Company, the Company believes that the loss of the 
services of Mr. Burkart will not have a material adverse effect on the 
Company. 
    

   The Company's future success will depend in large part upon its ability to 
attract and retain skilled scientific, management, operational and marketing 
personnel. Prior to this Offering, the Company has not had any employees or 
personnel whose responsibilities for the Company were focused primarily on 
sales or marketing. The Company faces competition for hiring such personnel 
from other companies, government entities and other organizations. There can 
be no assurance that the Company will continue to be successful in attracting 
and retaining such personnel. See "Use of Proceeds," "Management" and 
"Executive Compensation." 

                                      15 
<PAGE>

POTENTIAL CONFLICTS OF INTEREST 

   Edwin L. Harper, Ph.D., the Company's Chairman of the Board and Chief 
Executive Officer, also serves as the President and Chief Operating Officer 
of both Commodore and Applied and devotes a portion of his business and 
professional time and efforts to the respective businesses of Commodore and 
Applied. In addition, Paul E. Hannesson, Bentley J. Blum, Kenneth L. Adelman, 
Ph.D. and David L. Mitchell (the "Commodore Directors"), all of whom are 
directors of the Company, also serve as directors of Commodore and/or 
Applied. While the Company believes that its business and technologies are 
distinguishable from those of Commodore and Applied, and that it does not 
compete in the markets in which Commodore and Applied compete, Dr. Harper and 
the Commodore Directors may have potential conflicts of interest with respect 
to, among other things, potential corporate opportunities, business 
combinations, joint ventures and/or other business opportunities that may 
become available to them, the Company, Commodore and/or Applied. Moreover, 
while Dr. Harper has agreed to devote a majority of his business and 
professional time and efforts to the Company, potential conflicts of interest 
also include the amount of time and effort devoted by him to the affairs of 
Commodore and Applied. The Company may be materially adversely affected if 
Dr. Harper and/or the Commodore Directors choose to place the interests of 
Commodore and/or Applied before those of the Company. Each of Dr. Harper and 
the Commodore Directors has agreed that, to the extent such opportunities 
arise, he will carefully consider a number of factors, including whether such 
opportunities were presented to him in his capacity as an officer or director 
of the Company, whether such opportunities are within the Company's line of 
business or consistent with its strategic objectives and whether the Company 
will be able to undertake or benefit from such opportunities. In addition, 
the Company's Board of Directors has adopted a policy whereby any future 
transactions between the Company and any of its subsidiaries, affiliates, 
officers, directors, principal stockholders or any affiliates of the 
foregoing will be on terms no less favorable to the Company than could 
reasonably be obtained in "arm's length" transactions with independent third 
parties, and any such transactions will also be approved by a majority of the 
Company's disinterested outside directors. Dr. Harper and the Commodore 
Directors also owe fiduciary duties of care and loyalty to the Company under 
Delaware law. However, the failure of the Company's management to resolve any 
conflicts of interest in favor of the Company could materially adversely 
affect the Company's business, financial condition and results of operations. 

GOVERNMENT REGULATION 

   
   The Company and its customers are required to comply with a number of 
federal, state and local laws and regulations in the areas of safety, health 
and environmental controls, including without limitation, the Resource 
Conservation and Recovery Act, as amended ("RCRA"), and the Occupational 
Safety and Health Act of 1970 ("OSHA"), which may require the Company, its 
prospective working partners or its customers to obtain permits or approvals 
to utilize CST and related equipment on certain job sites. In addition, if 
the Company begins to market CST internationally, the Company will be 
required to comply with laws and regulations and, when applicable, obtain 
permits or approvals in those other countries. There is no assurance that 
such required permits and approvals will be obtained. Furthermore, 
particularly in the environmental remediation market, the Company may be 
required to conduct performance and operating studies to assure government 
agencies that CST and its by-products do not pose environmental risks. There 
is no assurance that such studies, if successful, will not be more costly or 
time-consuming than anticipated. Further, if new environmental legislation or 
regulations are enacted or existing legislation or regulations are amended, 
or are interpreted or enforced differently, the Company, its prospective 
working partners and/or its customers may be required to meet stricter 
standards of operation and/or obtain additional operating permits or 
approvals. There can be no assurance that the Company will meet all of the 
applicable regulatory requirements. Failure to obtain such permits, or 
otherwise to comply with such regulatory requirements, could have a material 
adverse effect on the Company's business, financial condition and results of 
operations. See "Business -- Government Regulation." 
    

DILUTION 

   
   Purchasers of shares of Common Stock in this Offering will experience an 
immediate and substantial dilution of $4.16 per share (based on an assumed 
initial public offering price of $6.00 per share of Common Stock in this 
Offering), or approximately 69.3%, in the net tangible book value of the 
shares of Common Stock purchased by them in this Offering. Additional 
dilution to future net tangible book value per share may occur upon 
    

                                      16 
<PAGE>

exercise of outstanding stock options and warrants (including the Warrants 
and the Representative's Warrants) and may occur, in addition, if the Company 
issues additional equity securities in the future, including issuances of 
Common Stock pursuant to the conversion of the Convertible Preferred Stock. 
Applied acquired its shares of Common Stock for cash consideration which was 
substantially less than the initial public offering price of the shares of 
Common Stock offered hereby. As a result, new investors will bear 
substantially all of the risks inherent in an investment in the Company. See 
"Dilution" and "Certain Relationships and Related Transactions." 

CONTROL BY PRINCIPAL STOCKHOLDER; LOAN TO COMMODORE 

   Applied is currently the sole stockholder of the Company and, after 
completion of this Offering, will own approximately 87.0% of the outstanding 
Common Stock of the Company (approximately 60.6% assuming conversion of all 
Convertible Preferred Stock and exercise of all Warrants). Applied is a 
public company whose shares are traded on the American Stock Exchange. 
Commodore, which owns 69.3% of the common stock of Applied, is also a public 
company whose shares are quoted on the OTC Bulletin Board. Accordingly, 
events or circumstances having an adverse effect on either or both of 
Commodore or Applied, including fluctuations in their respective market 
prices, could have a material adverse effect on the market prices of the 
Securities. 

   Bentley J. Blum, a director of the Company, beneficially owned, directly 
and through entities controlled by him, approximately 51.8% of the 
outstanding common stock of Commodore as of December 31, 1996. Paul E. 
Hannesson, a director of the Company, beneficially owned approximately 11.6% 
of the outstanding Commodore common stock as of such date. Accordingly, 
through his indirect beneficial ownership of a controlling stock interest in 
Applied, Mr. Blum will be able to control the voting of Applied's shares at 
all meetings of stockholders of the Company and, because the Common Stock 
does not have cumulative voting rights, will be able to determine the outcome 
of the election of all of the Company's directors and determine corporate and 
stockholder action on other matters. Messrs. Blum and Hannesson are also 
directors of both Commodore and Applied. See "-- Potential Conflicts of 
Interest," "Management," "Principal Stockholders" and "Certain Relationships 
and Related Transactions." 

   
   In the event the Over-allotment Option is exercised, the Company intends 
to enter into a two-year revolving credit agreement with Commodore. Pursuant 
to such agreement, the Company may lend the net proceeds, if any, from the 
exercise of the Over-allotment Option (estimated to be up to approximately 
$3,250,000) to Commodore for its working capital needs. To the extent of such 
borrowings, cash resources will be diverted from use in the Company's 
business, and possibly at times when the Company's liquidity and access to 
funding may be limited. There can be no assurance that Commodore will 
promptly repay any outstanding amounts under the revolving credit agreement 
or not otherwise default under such agreement. In the event of any such 
default, the collateral held by the Company under the agreement may not be 
sufficient to adequately compensate the Company for any loans made 
thereunder. See "Use of Proceeds," "Management's Discussion and Analysis of 
Financial Condition and Results of Operations -- Liquidity and Capital 
Resources" and "Certain Relationships and Related Transactions -- Loan 
Agreement with Commodore." 
    

RISK OF PRODUCT LIABILITY 

   The Company proposes initially to license CST equipment and, upon 
completion of its proposed Atlanta facility, to manufacture all or a 
substantial portion of that equipment. The equipment will be utilized in a 
variety of industrial and other settings, and will be used to handle 
materials resulting from pressurized and chemical processes. Accordingly, the 
equipment will be subject to risks of breakdowns and malfunctions, and there 
exists the possibility of claims for personal injury and business losses 
arising out of such breakdowns and malfunctions. There can be no assurance 
that the Company's product liability insurance will provide coverage against 
all claims, and claims may be made against the Company (even if covered by 
the Company's insurance policy) for amounts substantially in excess of 
applicable policy limits. Any such event could have a material adverse effect 
on the Company's business, financial condition and results of operations. 

NO DIVIDENDS ON COMMON STOCK 

   The Company has never paid any dividends on its Common Stock, and has no 
plans to pay dividends on its Common Stock in the foreseeable future. 
Furthermore, pursuant to the terms governing the Convertible Pre- 

                                      17 
<PAGE>

ferred Stock, the Company's Board of Directors may not declare dividends 
payable to holders of Common Stock unless and until all accrued cash 
dividends through the most recent past annual dividend payment date have been 
paid in full to holders of the Convertible Preferred Stock. See "Dividend 
Policy." 

POTENTIAL ADVERSE EFFECT ON MARKET PRICE OF SECURITIES FROM FUTURE SALES OF 
COMMON STOCK 

   Future sales of Common Stock by Applied or other stockholders (including 
option holders) under Rule 144 of the Securities Act of 1933, as amended (the 
"Securities Act"), or through outstanding registration rights granted to the 
holders of the Representative's Warrants, could have an adverse effect on the 
market prices of the Securities. The Company and Applied, as well as all 
holders of outstanding securities exercisable for or convertible into Common 
Stock, have agreed not to, directly or indirectly, issue, agree or offer to 
sell, sell, transfer, assign, distribute, grant an option for purchase or 
sale of, pledge, hypothecate or otherwise encumber or dispose of any 
beneficial interest in such securities for a period of 13 months following 
the date of this Prospectus without the prior written consent of the 
Representative. Sales of substantial amounts of Common Stock or the 
perception that such sales could occur could adversely affect prevailing 
market prices for the Convertible Preferred Stock, the Common Stock and/or 
the Warrants. All of the shares of Convertible Preferred Stock, shares of 
Common Stock and Warrants, and all shares of Common Stock issuable upon 
conversion or exercise of such Securities, will have been registered under 
the Securities Act and may be immediately converted into or exercised for up 
to 6,250,000 additional shares of Common Stock, all of which are immediately 
salable. Such sales may further adversely affect the market price of the 
Common Stock. See "Shares Eligible For Future Sale." 

NO ASSURANCE OF PUBLIC TRADING MARKET; ARBITRARY DETERMINATION OF PUBLIC 
OFFERING PRICES 

   Prior to this Offering, there has been no public market for the 
Convertible Preferred Stock, the Common Stock or the Warrants, and there can 
be no assurance that an active trading market for any of the Securities will 
develop or, if developed, be sustained after the Offering. The initial public 
offering prices of the Securities offered hereby and the terms of the 
Convertible Preferred Stock and Warrants have been arbitrarily determined by 
negotiations between the Company and the Representative, and do not 
necessarily bear any relationship to the Company's assets, book value, 
results of operations or any other generally accepted criteria of value. See 
"Underwriting." 

POSSIBLE VOLATILITY OF MARKET PRICES 

   The stock market has from time to time experienced significant price and 
volume fluctuations that may be unrelated to the operating performances of 
specific companies. Announcements of new technologies and changing policies 
and regulations of the federal government and state governments and other 
external factors, as well as potential fluctuations in the Company's 
financial results, may have a significant impact on the prices of the 
Securities. 

CERTAIN ANTI-TAKEOVER PROVISIONS AND POTENTIAL ADVERSE EFFECT ON MARKET PRICE 
OF SECURITIES FROM ISSUANCE OF PREFERRED STOCK 

   The Company's Certificate of Incorporation and By-Laws contain certain 
provisions that could have the effect of delaying or preventing a change of 
control of the Company, which could limit the ability of security holders to 
dispose of their Convertible Preferred Stock, Common Stock and/or Warrants in 
such transactions. The Certificate of Incorporation authorizes the Board of 
Directors to issue one or more series of preferred stock without stockholder 
approval. Such preferred stock could have voting and conversion rights that 
adversely affect the voting power of the holders of Convertible Preferred 
Stock and/or Common Stock, or could result in one or more classes of 
outstanding securities that would have dividend, liquidation or other rights 
superior to those of the Convertible Preferred Stock and/or Common Stock. 
Issuance of such preferred stock may have an adverse effect on the then 
prevailing market price of the Convertible Preferred Stock, Common Stock 
and/or Warrants. Additionally, the Company is subject to the anti-takeover 
provisions of Section 203 of the Delaware General Corporation Law, which 
prohibits the Company from engaging in a "business combination" with an 
"interested stockholder" for a period of three years after the date of the 
transaction in which the person became an inter- 

                                      18 
<PAGE>

ested stockholder, unless the business combination is approved in a 
prescribed manner. Section 203 could have the effect of delaying or 
preventing a change of control of the Company. See "Description of Securities 
- -- Preferred Stock" and "-- Section 203 of the Delaware Law." 

LIMITATIONS ON LIABILITY OF DIRECTORS AND OFFICERS 

   The Company's Certificate of Incorporation includes provisions to 
eliminate, to the full extent permitted by the DGCL as in effect from time to 
time, the personal liability of directors of the Company for monetary damages 
arising from a breach of their fiduciary duties as directors. The Certificate 
of Incorporation also includes provisions to the effect that (subject to 
certain exceptions) the Company shall, to the maximum extent permitted from 
time to time under the law of the State of Delaware, indemnify, and upon 
request shall advance expenses to, any director or officer to the extent that 
such indemnification and advancement of expenses is permitted under such law, 
as it may from time to time be in effect. In addition, the Company's By-Laws 
(the "By-Laws") require the Company to indemnify, to the full extent 
permitted by law, any director, officer, employee or agent of the Company for 
acts which such person reasonably believes are not in violation of the 
Company's corporate purposes as set forth in the Certificate of 
Incorporation. As a result of such provisions in the Certificate of 
Incorporation and the By-Laws, stockholders may be unable to recover damages 
against the directors and officers of the Company for actions taken by them 
which constitute negligence, gross negligence or a violation of their 
fiduciary duties, which may reduce the likelihood of stockholders instituting 
derivative litigation against directors and officers and may discourage or 
deter stockholders from suing directors, officers, employees and agents of 
the Company for breaches of their duty of care, even though such action, if 
successful, might otherwise benefit the Company and its stockholders. See 
"Executive Compensation -- Limitation of Directors' and Officers' Liability 
and Indemnification." 

POSSIBLE ISSUANCE OF ADDITIONAL PREFERRED STOCK SENIOR TO THE CONVERTIBLE 
PREFERRED STOCK 

   In addition to the Convertible Preferred Stock, the Company will have 
approximately 3,125,000 shares of Preferred Stock authorized after the 
designation of Convertible Preferred Stock which may be issued with dividend, 
liquidation, voting and redemption rights senior to the Convertible Preferred 
Stock; provided, however, that any such issuance of senior preferred stock 
must be approved by the holders of a majority of the outstanding shares of 
Convertible Preferred Stock. See "Description of Securities -- Convertible 
Preferred Stock." 

SPECULATIVE NATURE OF THE WARRANTS; POSSIBLE REDEMPTION OF WARRANTS 

   
   The Warrants do not confer any rights of Common Stock ownership on their 
holders, such as voting rights or the right to receive dividends, but merely 
represent the right to acquire shares of Common Stock at a fixed price for a 
limited period of time. Specifically, commencing one year after the date of 
this Prospectus, holders of the Warrants may exercise their right to acquire 
Common Stock and pay an exercise price of $8.40 per share, subject to 
adjustment upon the occurrence of certain events, until five years after the 
date of this Prospectus, after which date any unexercised Warrants will 
expire and have no further value. Moreover, following the completion of this 
Offering, the market value of the Warrants is uncertain and there can be no 
assurance that the market value of the Warrants will equal or exceed their 
initial public offering price. There can be no assurance that the market 
price of the Common Stock will ever equal or exceed the exercise price of the 
Warrants, and consequently, whether it will ever be profitable for holders of 
the Warrants to exercise the Warrants. 

   Commencing 18 months after the date of this Prospectus, the Warrants are 
subject to redemption at $.10 per Warrant on 30 days' prior written notice 
provided that the average closing sale price of the Common Stock equals or 
exceeds $18.00 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 right to exercise the Warrants after the expiration 
of the 30-day notice period. Upon receipt of a notice of redemption, holders 
will 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 then-prevailing 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. In the event that holders of the Warrants 
elect not to exercise their Warrants upon notice of redemption, the unexer- 
    

                                      19 
<PAGE>

cised Warrants will be redeemed prior to exercise, and the holders thereof 
will lose the benefit of the appreciated market price of the Warrants, if 
any, and/or the difference between the market price of the underlying Common 
Stock as of such date and the exercise price of such Warrants, as well as any 
possible future price appreciation in the Common Stock. See "Description of 
Securities -- Warrants." 

ADVERSE EFFECT OF POSSIBLE REDEMPTION OF PREFERRED STOCK 

   
   Commencing March  , 2000 and extending through March  , 2001, the 
Convertible Preferred Stock may be redeemed by the Company in whole but not 
in part, provided certain market conditions are met or alternatively, after 
March  , 2001 may be redeemed by the Company in whole or in part at any time 
at specified premiums in excess of the initial public offering price of the 
Convertible Preferred Stock. The Company may choose to redeem the Convertible 
Preferred Stock rather than incur the cost of keeping a registration 
statement current with the Securities and Exchange Commission (the 
"Commission") for the shares of Common Stock underlying the Convertible 
Preferred Stock. Redemption or automatic conversion of the Convertible 
Preferred Stock could force the holders to convert the Convertible Preferred 
Stock at a time when it may be disadvantageous for the holders to do so, to 
sell the Convertible Preferred Stock at the then current market price when 
they might otherwise wish to hold the Convertible Preferred Stock for 
possible additional appreciation and receipt of dividends, or to accept the 
redemption price, which is likely to be substantially less than the market 
value of the Convertible Preferred Stock at the time of redemption. 
    

CURRENT PROSPECTUS AND STATE BLUE SKY REGISTRATION 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. There can be no 
assurance that the Company will be able 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 will be able to maintain a current prospectus 
relating thereto until the expiration of the Warrants. 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. The Warrants will be separately 
tradeable immediately after this Offering. In the event investors 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 will 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."

                               USE OF PROCEEDS 

   The net proceeds to the Company from the sale of the Securities offered 
hereby (assuming an initial public offering price of $10.10 per Preferred 
Unit, consisting of one share of Convertible Preferred Stock at $10.00 per 
share and one Warrant at $.10 per Warrant, and $6.10 per Common Unit, 
consisting of one share of Common Stock at $6.00 per share and one Warrant at 
$.10 per Warrant), after deduction of underwriting discounts and other 
estimated offering expenses, are estimated to be approximately $21,093,500 
(approximately $24,337,550 if the Over-allotment Option is exercised in 
full). The Company intends to utilize such net proceeds as follows:

- ------ 
(1) Includes the hiring of additional personnel (including marketing 
    personnel) and the costs associated with conducting ongoing tests, 
    demonstrations and enhancements of CST. See "Business -- Research and 
    Development." 

   
(2) Consists of costs anticipated to be incurred in connection with 
    purchasing the equipment or licensing technology necessary to manufacture 
    the modules and produce the proprietary chemicals used in CST. See 
    "Business -- Proposed Manufacturing Operations." 

(3) Consists of costs anticipated to be incurred in connection with equipping 
    a new facility of approximately 20,000 square feet near Atlanta, Georgia, 
    which the Company has leased and began occupying in March 1997 and which 
    will comprise the Company's administrative offices, research and testing 
    laboratories and CST manufacturing plant. See "Business -- Proposed 
    Manufacturing Operations" and "-- Properties." 

(4) Represents funds which the Company intends to utilize to finance the 
    possible acquisitions of, or investments in, complementary (including 
    competitive) businesses, products or technologies. The Company currently 
    has no commitments or agreements with respect to any such acquisitions or 
    investments. See "Risk Factors -- Unspecified Acquisition-Related Risks." 
    

(5) Consists of costs anticipated to be incurred in connection with 
    purchasing CST components for use in connection with initial 
    demonstrations and/or installations of CST at customer sites. 

   
(6) Expenditures in respect of collaborative arrangements will include 
    salaries and benefits of personnel, equipment design and procurement 
    costs, costs of leasing or otherwise obtaining additional operating 
    facilities, analytical and other testing costs, professional fees, 
    insurance and other administrative expenses. In each arrangement, 
    personnel expenses may be expected to account for at least 50% of the 
    costs of each collaborative arrangement, and equipment costs are likely 
    to constitute the next largest component of expenditures. As of the date 
    of this Prospectus, the Company has not determined the amount of net 
    proceeds of this Offering to be applied to any one particular proposed 
    collaborative arrangement because the Company is currently in 
    negotiations with a number of companies involving, among other issues, 
    the level of its proposed funding commitment. The estimated allocation of 
    the net proceeds for funding of proposed collaborative arrangements is on 
    an aggregate basis. In addition, in the event a definitive agreement is 
    not entered into by the Company and Teledyne Brown or Sverdrup, 
    respectively, on or before August 31, 1997, such memorandum of 
    understanding may be terminated by either company upon written notice. 
    See "Risk Factors -- No Assurance of Collaborative Agreements or Project 
    Awards" and "Business -- Collaborative Working Arrangements."

(7) Working capital and general corporate purposes include amounts required 
    to pay officers' salaries, professional fees, ongoing public reporting 
    costs, ongoing license fees and royalties, office-related expenses and 
    other corporate expenses, including interest and overhead. In the event 
    the Over-allotment Option is exercised, the Company intends to enter into 
    a two-year revolving credit agreement with Commodore. Pursuant to such 
    agreement, the Company may lend the net proceeds, if any, from the 
    exercise of the Over-allotment Option (estimated to be up to 
    approximately $3,250,000) to Commodore for its working capital needs. In 
    the event that the Company does not consummate the revolving credit 
    agreement, such funds will be utilized by the Company for working capital 
    and general corporate purposes. See "Risk Factors -- Control by Principal 
    Stockholder; Loan to Commodore," "Management's Discussion and Analysis of 
    Financial Condition and Results of Operations -- Liquidity and Capital 
    Resources" and "Certain Relationships and Related Transactions -- Loan 
    Agreement with Commodore." 
    

   The Company believes that the net proceeds of this Offering will be 
sufficient to meet its cash, operational and liquidity requirements for a 
minimum of 24 months after the date of this Prospectus. While the initial 
allocation of the net proceeds of this Offering represents the Company's best 
estimates of their use, the amounts actually expended for these purposes may 
vary significantly from the specific allocation of the net proceeds set forth 
above, depending on numerous factors, including changes in the general 
economic and/or regulatory climate, and the progress and market acceptance of 
the Company's technology. See "Risk Factors -- Broad Discretion in 
Application of Proceeds." However, there can be no assurance that the net 
proceeds of the Offering will satisfy the Company's requirements for any 
particular period of time. The Company anticipates that, after 24 months from 
the receipt of the net proceeds of this Offering, additional funding may be 
needed. No assurance can be given that such additional financing will be 
available on terms acceptable to the Company, if at all. See "Risk Factors -- 
Potential Need for Additional Financing." Pending specific allocation of the 
net proceeds of this Offering, the net proceeds will be invested in 
short-term, investment grade, interest-bearing obligations.

December 31, 1996 and (b) at December 31, 1996, as adjusted giving effect to 
the sale by the Company of the Securities offered hereby (at an assumed 
initial public offering price of $10.10 per Preferred Unit, consisting of one 
share of Convertible Preferred Stock at $10.00 per share and one Warrant at 
$.10 per Warrant, and $6.10 per Common Unit, consisting of one share of 
Common Stock at $6.00 per share and one Warrant at $.10 per Warrant) and the 
initial application of the estimated net proceeds therefrom. See "Use of

                               DIVIDEND POLICY 

   
   The Company has never declared or paid cash dividends, and does not intend 
to pay any dividends in the foreseeable future on its shares of Common Stock. 
Pursuant to the terms governing the Convertible Preferred Stock, the 
Company's Board of Directors may not declare dividends payable to holders of 
Common Stock unless and until all accrued cash dividends through the most 
recent past annual payment date have been paid in full to holders of the 
Convertible Preferred Stock. Earnings of the Company, if any, not paid as 
dividends to holders of the Convertible Preferred Stock are expected to be 
retained for use in expanding the Company's business. The payment of 
dividends on the Common Stock is within the discretion of the Board of 
Directors of the Company and will depend upon the Company's earnings, if any, 
capital requirements, financial condition and such other factors as are 
considered to be relevant by the Board of Directors from time to time. The 
Company's future earnings, if any, will not initially be adequate for the 
payment of dividends on the Convertible Preferred Stock, in which event such 
dividends will be paid out of the Company's then capital surplus (the 
Company's net assets minus the aggregate par or stated value of the 
outstanding shares of the Company's capital stock), if any. On an as adjusted 
basis, after giving effect to this Offering, the Company's capital surplus as 
of December 31, 1996 was $22,071,700. The payment of dividends and any future 
operating losses will reduce such capital surplus, which may adversely affect 
the Company's ability to continue to pay dividends on the Convertible 
Preferred Stock. The failure to pay quarterly dividends will result in a 
reduction of the conversion price on the Convertible Preferred Stock and may 
give rise to voting rights to the holders of such Convertible Preferred 
Stock. See "Risk Factors -- Inadequate Dividend Coverage" and "Description of 
Securities -- Convertible Preferred Stock."

                                   DILUTION 

   
   At December 31, 1996, the Company's negative net tangible book value was 
$(164,160), or $(.02) per share of Common Stock. The net tangible book value 
of the Company is the tangible assets less total liabilities. After giving 
effect to the sale by the Company of the Securities offered hereby (assuming 
an initial public offering price of $10.10 per Preferred Unit, consisting of 
one share of Convertible Preferred Stock at $10.00 per share and one Warrant 
at $.10 per Warrant, and $6.10 per Common Unit, consisting of one share of 
Common Stock at $6.00 per share and one Warrant at $.10 per Warrant) and the 
initial application of the estimated net proceeds therefrom, the pro forma 
net tangible book value of the Company as of December 31, 1996 would have 
been approximately $21,148,804, or $1.84 per share. This represents an 
increase in net tangible book value per share of $1.86 to the Company's 
existing stockholders and an immediate dilution of $4.16 per share (or 69.3%) 
to new stockholders purchasing Common Stock and Convertible Preferred Stock 
in this Offering. The following table illustrates this dilution on a per 
share basis:

</TABLE>

   In the event the Over-allotment Option is exercised in full, the net 
tangible book value at December 31, 1996 would have been approximately 
$24,392,854 and the dilution of net tangible book value per share to new 
stockholders would have been approximately $3.92.

                   MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
                FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

GENERAL 

   The Company was organized in November 1995 and has had no commercial 
operations to date. Since its inception, the Company has been engaged 
principally in organizational activities, including developing a strategic 
operating plan, entering into contracts, hiring personnel, developing test 
modules and installing and operating modules on a limited basis for 
demonstration or test purposes. Accordingly, the Company has no relevant 
operating history upon which an evaluation of its performance and prospects 
can be made. The Company is subject to all of the business risks associated 
with a new enterprise, including, but not limited to, risks of unforeseen 
capital requirements, failure of market acceptance, failure to establish 
business relationships, and competitive disadvantages as against larger and 
more established companies. The report of the independent auditors with 
respect to the Company's financial statements included in this Prospectus 
includes a "going concern" qualification, indicating that the Company's 
significant losses and deficits in working capital and stockholders' equity 
raise substantial doubt about the Company's ability to continue as a going 
concern. 

   
   The Company has generated nominal revenues to date, and will not generate 
any material revenues until after the Company successfully completes the 
installation of modules in a significant number of industrial companies, of 
which no assurance can be given. During the period from November 15, 1995 
(date of inception) to June 30, 1996, the Company incurred a net loss of 
$(60,936). From July 1, 1996 to December 31, 1996, the Company incurred 
additional operating losses of $(853,804), and anticipates that it may 
continue to incur significant operating losses for the foreseeable future. 
There can be no assurance as to whether or when the Company will generate 
material revenues or achieve profitable operations. See "Business" and 
Financial Statements. 
    

DEPENDENCE ON SUPPLIERS 

   The Company has not to date conducted any manufacturing operations, but 
has relied on unaffiliated suppliers to provide fibers, membrane casings and 
other materials and components utilized in CST. The Company has not 
previously experienced any delays or difficulties in obtaining any of these 
items, although there can be no assurance that such difficulties may not be 
encountered in the future. The Company has allocated a portion of the net 
proceeds of this Offering to the establishment of a facility in Atlanta, part 
of which will be dedicated to operations related to the manufacturing of 
chemicals, fibers, membrance casings and other materials and components 
utilized in CST. See "Risk Factors -- Dependence on Strategic Components" and 
"Use of Proceeds." 

LIQUIDITY AND CAPITAL RESOURCES 

   
   The Company has to date financed its development efforts through direct 
equity investments and loans from Commodore and Applied. From November 15, 
1995 (date of inception) to December 31, 1996, the Company has purchased or 
constructed equipment totalling $201,109 and has incurred patent filing and 
maintenance costs of $22,456. As of December 31, 1996, the Company's 
aggregate indebtedness to Applied was $273,600. Effective December 1, 1996, 
Commodore sold 100% of the Company's capital stock and the capital stock of 
another subsidiary to Applied and assigned the Company's $976,200 of notes to 
Applied in consideration of $3,000,000 and, subject to any applicable 
stockholder approval and notification requirements, shall issue a seven-year 
warrant to purchase 7,500,000 shares of Applied common stock at $15.00 per 
share. Applied has agreed to contribute the entire amount of such $976,200 
Company indebtedness to the Company's equity prior to completion of this 
Offering. See "Certain Relationships and Related Transactions." 

   The Company has sustained losses of $(853,804) and $(60,936) for the six 
month period ended December 31, 1996 and for the period from November 15, 
1995 (date of inception) to June 30, 1996, respectively. The Company had no 
revenues during the period from November 15, 1995 (date of inception) to June 
30, 1996 and had revenues of $7,758 for the six-month period ended December 
31, 1996 as a result of billings from the Port of Baltimore field test of the 
CST process. Substantially all of the Company's losses are attributable to 
the expenses detailed above. At December 31, 1996 and June 30, 1996, the 
Company had working capital deficits 
    

                                      27 
<PAGE>

   
of $(134,677) and $(81,630), respectively, and stockholders' equity and 
deficit of $76,460 and $(60,836), respectively. The Company has received 
significant advances in working capital from Commodore and Applied which has 
allowed it to continue its operations. There can be no assurance that it will 
continue to receive such financial assistance. 
    

   The Company believes that the net proceeds of the Offering will be 
sufficient to meet its cash, operational and liquidity requirements for a 
minimum of 24 months after the date of this Prospectus. 

   
   The Company has leased a new facility of approximately 20,000 square feet 
near Atlanta, Georgia, which it began occupying in March 1997 and which will 
comprise the Company's administrative offices, research and testing 
laboratories and CST manufacturing plant. It is anticipated that 
approximately $2,000,000 of the net proceeds of this Offering will be 
required with respect to leasing such facility and related leasehold 
improvements. Additionally, it is anticipated that approximately $2,500,000 
of the net proceeds of this Offering will be required to purchase the 
equipment necessary to manufacture the modules and produce the proprietary 
chemicals used in CST. Prior to the Company's facility becoming operational 
for manufacturing, the Company anticipates spending approximately $1,200,000 
of the net proceeds of this Offering to purchase CST components for use in 
connection with initial demonstrations and/or installations of CST at 
customer sites. The Company is continuing to further the development of CST 
through additional testing, demonstrations and enhancements which will 
require the hiring of additional personnel and additional research and 
development costs. See "Use of Proceeds" and "Business -- Proposed 
Manufacturing Operations" and "-- Properties." 

   The Company has also allocated $1,250,000 of the net proceeds of this 
Offering to finance possible acquisitions of, or investments in, 
complementary (including competitive) businesses, products or technologies. 
The Company currently has no commitments or agreements with respect to any 
such acquisitions or investments. See "Risk Factors -- Unspecified 
Acquisition-Related Risks." 

   The Company has allocated $1,000,000 of the net proceeds of this Offering 
for the funding of proposed collaborative arrangements. These costs include, 
but are not limited to, salaries and benefits of personnel, equipment design 
and procurement costs, cost of leasing or otherwise obtaining additional 
operating facilities, analytical and other testing costs, professional fees, 
insurance and other administrative expenses. As of the date of this 
Prospectus, the Company has not determined the amount of net proceeds of this 
Offering to be applied to any one particular proposed collaborative 
arrangement because the Company is currently in negotiations with a number of 
companies involving, among other issues, the level of its proposed funding 
commitment. The estimated allocation of the net proceeds for funding of 
proposed collaborative arrangements is on an aggregate basis. In addition, in 
the event a definitive agreement is not entered into by the Company and 
Teledyne Brown or Sverdrup, respectively, on or before August 31, 1997, such 
memorandum of understanding may be terminated by either company upon written 
notice. See "Risk Factors -- No Assurance of Collaborative Agreements or 
Project Awards," "Use of Proceeds" and "Business -- Collaborative Working 
Arrangements." 

   In the event the Over-allotment Option is exercised, the Company intends 
to enter into a two-year revolving credit agreement with Commodore. Pursuant 
to such agreement, the Company may lend the net proceeds, if any, from the 
exercise of the Over-allotment Option (estimated to be up to approximately 
$3,250,000) to Commodore for its working capital needs. Borrowings under the 
agreement will be secured by Commodore's pledge of 2,000,000 shares of 
Applied common stock held by it and will bear interest at the rate of 10% per 
annum, with interest payable quarterly on outstanding amounts. The principal 
balance outstanding will be due on the second anniversary of the date of such 
agreement. The Company's obligation to lend such funds to Commodore is 
subject to a number of conditions, including review by the Company of the 
proposed use of such funds by Commodore. See "Risk Factors -- Control by 
Principal Stockholder; Loan to Commodore," "Use of Proceeds" and "Certain 
Relationships and Related Transactions -- Loan Agreement with Commodore." 
    

   Pursuant to an assignment of technology agreement between the Company and 
Srinivas Kilambi, Ph.D., the Company's Vice President-Technology, the Company 
agreed to pay Dr. Kilambi a royalty through December 3, 2002 equal to 2% of 
the Company's revenues actually received and attributed to the commercial 
application of the technology acquired from Dr. Kilambi, except for 
applications related to the radionuclides technetium and rhenium, for which 
Dr. Kilambi is entitled to receive a royalty of .66% of net sales (less 
allowances for returns, discounts, commissions, freight, and excise or other 
taxes). Pursuant to the license agreement with Lockheed 

                                      28 
<PAGE>

Martin, the Company made an initial cash payment of $50,000 upon the 
execution of the agreement and is obligated to pay, commencing in the third 
year of the agreement, a royalty to Lockheed Martin of 2% of net sales (less 
allowances for returns, discounts, commissions, freight, and excise or other 
taxes) up to total net sales of $4,000,000 and 1% of net sales thereafter. In 
addition, the Company has agreed to guarantee Lockheed Martin, commencing in 
the third year of the agreement, an annual minimum royalty of $15,000. See 
"Business -- Commercialization and Marketing Strategy -- Radionuclide/Mixed 
Waste Separation." Payment of such royalties to Dr. Kilambi and Lockheed 
Martin is based on Company revenues and is not related to or contingent upon 
the Company attaining profitability or positive cash flow. As a result, such 
payments will adversely affect operating results and divert cash resources 
from use in the Company's business, and possibly at times when the Company's 
liquidity and access to funding may be limited. See "Business -- Intellectual 
Property" and "Certain Relationships and Related Transactions -- Organization 
and Capitalization of the Company." 

RECENT PRONOUNCEMENTS OF THE FINANCIAL ACCOUNTING STANDARDS BOARD 

   The Financial Accounting Standards Board has issued Statements of 
Financial Accounting Standard Statement No. 121, "Accounting for Long Lived 
Assets" and No. 123, "Accounting and Disclosure of Stock-Based Compensation." 
Statement No. 121 is effective for years beginning after December 15, 1995. 
The effect of adoption of Statement No. 121 will not have a material effect 
on the Company's financial statements. Statement No 123 is effective for 
years beginning after December 15, 1995. The effect of adoption of Statement 
No. 123 is not expected to have a material effect on the Company's financial 
statements as the Company has adopted only the disclosure requirements of 
Statement No. 123. 

NET OPERATING LOSS CARRYFORWARDS 

   
   As of December 31, 1996, the Company had net operating loss carryforwards 
of approximately $914,000, which expire in the year 2011. The amount of net 
operating loss carryforward that can be used in any one year will be limited 
by the applicable tax laws which are in effect at the time such carryforward 
can be utilized. A valuation allowance of $311,000 has been established to 
offset any benefit from the net operating loss carryforward as it cannot be 
determined when or if the Company will be able to utilize the net operating 
losses.

                                   BUSINESS 

GENERAL 

   The Company has developed and intends to commercialize its membrane 
separation and recovery system called CST. Based on the results of more than 
100 laboratory and other tests to date, the Company believes that CST can 
separate and recover chrome, chromium, cadmium, silver, mercury, platinum, 
lead, zinc, nickel, trichlorethylene, polychlorinated biphenyls, methylene 
chloride, amino acids, antibiotics, radionuclides, and other organic and 
inorganic targeted substances from liquid or gaseous feedstreams. CST 
utilizes a process whereby a contaminated liquid or gaseous feedstream is 
introduced into a fibrous membrane unit or module containing a proprietary 
chemical solution, the composition of which is customized depending on the 
types and concentrations of compounds in the feedstream. As the feedstream 
enters the membrane, the targeted substance reacts with CST's proprietary 
chemical solution and is extracted through the membrane into a strip solution 
where it is then stored. The remaining feedstream is either recycled or 
discharged as non-toxic effluent. In some instances, additional treatment may 
be required prior to disposal. 

   CST is distinguishable from other existing forms of membrane filtration 
technology in that it: 

   o  requires low initial capital costs and low operating costs; 

   o  has the capability of treating a wide variety of elements and compounds 
      in a wide variety of industrial settings at great speed and with a high 
      degree of effectiveness, regardless of contaminant concentrations, 
      volume requirements and other variables; 

   o  is environmentally safe, in most instances producing no sludges or 
      other harmful by-products which would require additional post-treatment 
      prior to disposal; 

   o  can selectively extract target substances, while extracting 
      substantially fewer unwanted substances; 

   o  can typically operate on-site and in less than 40 square feet of space 
      for the entire system; 

   o  can extract metals, organic chemicals and other elements and compounds 
      in degrees of concentration and purity which permit their reuse; and 

   o  has the capability, in a single process application, of selectively 
      extracting multiple elements or compounds from a mixed process stream. 

   
   In August 1996, the Company completed an on-site demonstration of CST for 
the decontamination of chromium-contaminated groundwater at the Port of 
Baltimore, Maryland. During this demonstration, a CST unit, in a single 
feedstream pass-through, reduced the contamination level of chromium from 
more than 400 parts per million (ppm) to less than one ppm. The results of 
this test were verified by Artesian Laboratories, Inc., an independent 
testing laboratory. The Company has since completed additional on-site 
demonstrations of CST at the Port of Baltimore with similar results. Due to 
the success of such demonstrations, in February 1997 the State of Maryland 
informed the Company that it will recommend including the CST process as an 
eligible technology in the bid specifications to remediate the groundwater at 
the Port of Baltimore. Based on management studies and discussions with 
metals industry executives, the Company believes that CST represents a 
significant technological advancement in the area of environmental 
remediation as the only technology capable of on-site chromium removal and 
recovery that enables effluent discharge without additional treatment. 
    

   In September 1996, the Company installed a commercial scale CST unit at a 
Columbus, Ohio metal plating company. DLZ Laboratories, Inc., an independent 
testing laboratory, verified that the CST unit processed the initial batch of 
process effluent stream and reduced nickel and zinc contamination from 900 
ppm to 2 ppm in one hour. The Company has continued to operate this CST unit 
to process nickel and zinc effluent streams containing concentrations of 200 
to 400 ppm, and the unit has consistently reduced the contaminant levels to 1 
to 5 ppm. The decontaminated process effluent stream is being recycled into 
the plating line rinse tanks, saving the plating company its normal 
consumption of make-up water at a rate of five gallons per minute. The 
recovered nickel and zinc solution is currently being analyzed by the plating 
company for reuse in its plating operations. 

   In January 1997, the Company entered into a license agreement with 
Lockheed Martin, manager of Oak Ridge. Under the terms of the agreement, the 
Company received the exclusive worldwide license, subject to a government use 
license, to use and develop the technology related to the separation of the 
radionuclides technetium and rhenium from mixed wastes containing radioactive 
materials. Based on tests conducted at Oak Ridge 

                                      30 
<PAGE>

since May 1994, the Company believes that this technology is capable of 
selectively extracting and recovering technetium, rhenium and other 
radioactive isotopes as a concentrated aqueous solution which can be reused 
in various scientific applications or disposed of by government-approved 
techniques including long-term storage. The Company believes that this 
technology can be used to remediate nuclear waste tanks stored at the U.S. 
Department of Energy's atomic energy plants in Rocky Flats, Colorado, Idaho 
Falls, Idaho, Paducah, Kentucky, Weldon Springs, Missouri, Frenchman Flat, 
Nevada, Los Alamos, New Mexico, Aiken, South Carolina, Oak Ridge, Tennessee, 
Pantex, Texas and Hanford, Washington, and intends to pursue such 
opportunities. According to Department of Energy sources, there are 
approximately 100 million gallons of mixed radioactive and hazardous chemical 
waste stored at these plants. 

   The Company will market its technology to industries engaged in 
metallurgical processing, metal plating and mining, as well as companies 
producing organic chemicals and biochemicals and those engaged in gas 
separation. The Company is also targeting governmental agencies that have 
sites which require remediation, and has already completed an on-site 
demonstration at the Port of Baltimore. 

   The Company intends to pursue collaborative joint working and marketing 
arrangements with, or acquisitions of or investments in, companies that have 
a presence in target markets and those that focus on obtaining environmental 
remediation projects, including clean-up of harbors, groundwater and nuclear 
waste sites. Although the Company has entered into memorandums of 
understanding for proposed working arrangements with Teledyne Brown and 
Sverdrup, and is bidding on certain projects, there can be no assurance that 
any of these activities will result in definitive collaborative agreements or 
project awards. Even if project contracts are awarded to the Company, CST has 
never been utilized on a large-scale basis, and there is no assurance that 
this technology will perform successfully on a large-scale commercial basis, 
or that it will be profitable to the Company. There can also be no assurance 
that this technology will not be superseded by other competing technologies. 

MARKET OVERVIEW 

   Based on market data compiled by the Company, the Company estimates that, 
as of August 1, 1996, there were approximately 7,500 companies operating 
metal plating and metal finishing facilities in the United States, and an 
additional 1,500 such facilities in Canada. Based on estimated sales by these 
facilities, the Company believes that on average each of these facilities 
could utilize four to ten CST membrane units. The Company estimates that, as 
of such date, there were approximately 50 companies in the United States 
involved in industrial gas separation, and based on these companies' 
estimated sales, the Company believes that on average each of these companies 
could utilize two to four membrane units operating at significant volumes. 
Further, as of August 1, 1996, based on market data compiled by the Company, 
the potential market from organic chemical companies is in excess of 10,000 
companies in the United States. Based on these companies' estimated sales, 
the Company believes that on average each of these companies could utilize 
two to four membrane units operating at significant volumes. Additionally, as 
of such date, there were more than 5,000 biochemical, bulk drug manufacturing 
and pharmaceutical companies operating in the United States and Canada, and 
based on these companies' estimated sales, the Company believes that on 
average the typical such company could utilize two to four membrane units 
operating at substantial volumes. The Company believes that the potential 
international market for each of the above applications could be twice the 
size of the North American market. Federal, state and local government 
entities are also a potential market for the Company, particularly in the 
area of environmental remediation and clean-up. 

   As with any new technology or process, or a significant advancement of an 
existing technology or process, there may be initial resistance to the use of 
CST on a large scale, and certain prospective projects for the Company may 
have already been committed to other forms of technology. In each case, the 
Company expects to introduce its process on a test basis through the 
introduction of sample membrane units to demonstrate the efficacy of the 
technology, with the aim of full installation and/or project awards based on 
the performance of the sample units. 

ALTERNATIVE SEPARATION TECHNOLOGIES 

   Membrane separation and extraction technologies have been utilized 
commercially for several decades. Prior to the development of CST, membrane 
separation and extraction capabilities were broken into four subranges, 
consisting of microfiltration, ultrafiltration, nanofiltration and reverse 
osmosis (hyperfiltration), each distinguished and defined by the relative 
particle size which the particular process was capable of separating from 

                                      31 
<PAGE>

the feedstream, and by whether the compounds were suspended or dissolved in 
the feedstream. Existing technologies currently in use for the treatment of 
solubilized feedstreams (in which the containment is dissolved, rather than 
suspended, in the feedstream) include: (i) ion exchange (wherein electrically 
charged ions that are electrochemically held by ion exchange resin beads are 
exchanged for ions of similar charge in a solution in which the beads are 
immersed), (ii) reverse osmosis (wherein solutions are desalted or 
concentrated by driving them through membranes using relatively high 
hydraulic pressure, resulting in contaminants being excluded or rejected by 
the membranes), (iii) precipitation (wherein chemicals are used to 
precipitate out the contaminants for eventual off-site disposal), (iv) 
ultrafiltration (wherein moderate hydraulic pressure is used to transfer 
water and low molecular weight species through a membrane while blocking 
relatively large-sized contaminants such as suspended solids, colloids and 
large organic molecules) and (v) chromatography (wherein mixtures are 
separated into their constituents by preferential adsorption on solids). 

CST 

   Although CST uses the same basic principles as other membrane separation 
technologies, the Company believes that CST represents a significant advance 
in membrane separation technology in the treatment of solubilized 
feedstreams. In contrast to the five alternative separation technologies 
described above, CST acts by separating and extracting the targeted 
material(s) from the feedstream, rather than extracting the feedstream from 
the targeted material(s). As a result, for the first time, a single process 
is capable of treating a wide variety of elements and compounds in a wide 
variety of industrial settings, and doing so at great speed and with a high 
degree of effectiveness regardless of particle size, volume requirements and 
other variables. The Company also believes that CST is the first membrane 
separation technology which is capable, in a single process application, of 
selectively extracting multiple elements or compounds from a mixed process 
stream. The CST membrane modules can also be configured in various sizes and 
numbers and for varying capacities, and operate on the manufacturing site at 
ambient temperatures and pressures. 

   CST involves injecting a contaminated liquid or gaseous feedstream into 
the Company-designed fibrous membrane unit or module. This module is 
continuously fed with a recycled stream of proprietary chemical solution 
whose composition will vary depending on the types of compounds in the 
feedstream. As the feedstream enters the membrane unit, the metal or other 
substance to be extracted reacts with the proprietary chemical solution in 
the fibrous membrane, and the metallic or other ions are extracted through 
the membrane into a strip solution which is concentrated and gathered in a 
separate storage container. The balance of the feedstream is either recycled 
or simply discharged as normal effluent. In some instances, additional 
treatment may be required prior to disposal, or disposal may need to be made 
in a regulated manner. The Company believes that CST can be utilized for the 
separation and recovery of chrome, chromium, cadmium, silver, mercury, 
platinum, lead, zinc, nickel, trichlorethylene, polychlorinated biphenyls, 
methylene chloride, amino acids, antibiotics, radionuclides, and other 
organic and inorganic substances. 

   The typical CST module is cylindrical in shape and can be situated on a 
surface or in an area the size of a desktop. The module casing is constructed 
of either steel or plastic (depending on the required durability for the 
particular process application), and contains the microporous fiber membrane 
through which the target element or compound is separated from the 
contaminated feedstream. At one end of the module, there is attached a set of 
pumps and tubing that feeds the contaminated feedstock from its point of 
origin (such as a metal plating tank or bath) into the module. Additional 
pumps and tubing are attached to feed and recycle the chemical solution which 
is the active element in the membrane, and discharge tubing or piping is 
attached at the other end of the module, to carry away the separated 
concentrated metal solution or other compound, and the wastewater and other 
non-reusable by-product. The Company plans to produce a range of modules that 
will precisely conform to the customer's requirements for volume and 
capacity, and thus accommodate the available space in the customer's 
facility. The Company also formulates the active chemical compound for the 
process in each customer application, and performs the initial installation 
of the equipment at the customer site. The customer will operate the 
equipment and, by computer hook-up, the Company will monitor the equipment 
and process while in operation.

LABORATORY AND OTHER TEST RESULTS 

   In more than 100 laboratory and other tests to date, CST has demonstrated 
the ability to successfully separate a variety of metals and other substances 
from liquid and gaseous process streams. In each instance, the process stream 
was reduced to levels approaching federal guidelines under the Federal Clean 
Water Act for the disposal of the reacted process stream as normal wastewater 
effluent, and the recovered materials were of sufficient quantity and purity 
as to economically permit the reuse thereof in most commercial applications. 
Test results included the following:

COMPETITIVE AND OPERATIONAL ASPECTS OF CST 

   The following chart highlights certain of the salient differences which 
the Company believes, based on the limited quantities of process streams 
tested, distinguish CST from other membrane separation technologies. As shown 
below, the Company believes that CST has substantially broader applications 
than most of the other technologies, and is generally capable of superior 
results in less time. Other than with respect to the Company's tests 
involving the separation and recovery of zinc, nickel and chromium, no other 
independent tests have been conducted by the Company to verify the accuracy 
of the specifications shown below.

COMMERCIALIZATION AND MARKETING STRATEGY 

   During the initial commercialization phase, the Company expects to lease 
the CST modules to customers, with the lease payments being due and payable 
after installation and successful start-up of the equipment. When replacement 
modules are required, the Company expects to supply these modules at a 
reasonable mark-up over their cost. As new patents are filed and issued, the 
Company may, for certain applications, determine to make a direct sale of the 
equipment with additional long-term royalty payment provisions. The Company 
also expects to obtain revenues through servicing the CST equipment, 
including periodic replacement of the membrane component. In addition to 
leasing and selling its equipment, the Company intends to charge its 
customers based on a percentage of the customer's actual cost savings derived 
from reduced disposal costs and recovered reusable materials. In applications 
in which reusable materials are not recovered, the Company's ongoing charges 
may be based on the volume of materials processed. Although the Company plans 
to focus its initial marketing efforts on domestic businesses, the Company 
will also be prepared to pursue international opportunities, which may arise 
from successful presentations to multinational corporations or from overseas 
referrals by domestic entities. 

   In specific industries and for specific applications, the Company intends 
to emphasize and exploit the following attributes of CST. 

   Metals Separation and Recovery 

   The Company's initial marketing efforts will be in the industrial sector, 
in which the separation and recovery of metal-bearing liquid solutions 
present a substantial market. Primary among the potential customers in this 
area are metal plating and metal finishing operations, which generate 
substantial volumes of mixed metals process streams for which no previous 
technology was available to effect proper separation. 

   In September 1996, the Company installed a commercial scale CST unit 
on-line at Plating Technology Inc., a Columbus, Ohio metal plating company 
("PTI"). The unit is currently operating on a continuous mode and, based on 
operating data results to date, is successfully separating and recovering 
nickel and zinc effluent streams with concentrations varying from 100 to 
1,000 ppm. DLZ Laboratories, Inc., an independent testing laboratory, 
verified that the CST unit processed the initial batch of process effluent 
stream and reduced nickel and zinc contamination from 900 ppm to 2 ppm in one 
hour. The Company's own data indicate that, in ongoing use on effluent 
streams containing nickel and zinc concentrations of 200 to 400 ppm, this CST 
unit has consistently reduced the level of contaminants to 1 to 5 ppm. The 
decontaminated process effluent stream is being recycled into PTI's plating 
line rinse tanks, saving PTI its normal consumption of make-up water at a 
rate of five gallons per minute. The recovered nickel and zinc solution is 
currently being analyzed by PTI for reuse in its plating operations. 

   Based on management studies and discussions with metals industry 
executives, the Company believes that the major competitive technology in 
this area is precipitation, which generates a metallic sludge by-product 
requiring further treatment prior to landfill disposal. By contrast, CST does 
not generate harmful metallic sludges, and instead enables close to 100% 
process water recycling, while also enabling recovery of valuable raw 
materials. As costs of environmental compliance continue to mount, the 
Company expects CST to become a preferred alternative to existing metals 
separation methods. 

   Gas Separation 

   The CST equipment and technology can also be utilized to separate and 
recover valuable gases (such as nitrogen) from mixed gaseous and liquid 
compounds. For example, nitrogen is used for a wide variety of process 
applications, including oil recovery, food processing, metal heat treatment, 
and pharmaceutical testing and development. 

   Nitrogen is typically obtained by separating it from oxygen, using 
processes such as cryogenic distillation, adsorption, catalytic removal, and 
permselective polymeric membrane separation. However, each of these processes 
has drawbacks, which can include high energy usage, high pressure and 
temperature requirements, and/or relatively low purity of the recovered gas. 
The CST process overcomes these drawbacks by yielding relatively pure 
nitrogen in a low-energy, low capital cost process conducted at ambient 
temperature and pressure. The Company has prepared a proposal for a prototype 
unit for the production of high-purity nitrogen for use in food processing, 
but has not otherwise developed a strategy or targeted a market for 
commercialization of the gas separation application.

   Organics Separation and Recovery 

   As of August 1, 1996, based on market data compiled by the Company, there 
were more than 10,000 organic chemical industry companies operating in the 
United States. These companies generate significant volumes of waste process 
streams, including mixed organic/non-organic streams. CST has been 
demonstrated to have significant capabilities in the separation and recovery 
of a variety of contaminants, including phenol and nitrophenol (a phenolic 
derivative), and the Company believes that such capabilities, although 
untested, extend to other organic chemicals such as volatile organic 
compounds, petrochemicals, other phenolic derivatives, olefin alkanes and 
acid gases. 

   Currently, the primary technology utilized in this area is activated 
carbon treatment. Like the other slow biological treatment processes utilized 
in this area, the by-products are often more toxic than the original 
compound. The Company intends to demonstrate to chemical manufacturers that 
CST is effective in dealing with the wide variety of contaminants generated 
by these businesses, and that use of CST will substantially reduce the 
environmental risks and costs associated with traditional separation methods. 

   Biochemicals Separation and Recovery 

   CST has also been demonstrated to have significant capabilities in the 
separation and recovery of biochemicals, including phenylalanine (an amino 
acid), and the Company believes that such capabilities, although untested, 
extend to other biochemicals such as proteins, other amino acids, 
antibiotics, glycerides, fatty acids, drug delivery vehicles and other 
pharmaceuticals. Mixed wastes containing these materials are generated in 
both research and development functions and in manufacturing functions. These 
materials have substantial value, and the Company intends to emphasize both 
the value of the recovered materials and the enhanced and speedier 
environmental compliance attributes of CST. 

   Currently, the primary competing technology in this area is 
chromatography, which requires substantially greater time to treat 
significant volumes of material, and is substantially less selective in the 
types of materials that can be separated from the liquid feedstream. 

   Environmental Remediation and Restoration 

   The Company believes that CST has significant potential for application to 
environmental remediation and restoration. The Company is currently involved 
in pilot projects for the decontamination of water in the Port of Baltimore, 
and for clean-up of trichlorethylene-contaminated groundwater on Cape Cod, 
Massachusetts. In the case of a project such as the Port of Baltimore 
project, it is expected that the remediating technology will be applied 
continuously over a period of many years, until the subject contamination (in 
the case of Baltimore, chromium leaching from underlying soil into the 
aquifer) has been demonstrated to have been abated for a significant period 
of time. 

   In contrast to other remediation technologies, the Company believes that 
CST has the attributes of low initial capital costs, low operating costs and 
the ability to recover heavy metals, organic chemicals and varied volatile 
organic compounds for reuse. 

   
   In August 1996, the Company completed an on-site demonstration of CST for 
the decontamination of water in the Port of Baltimore. During seven hours of 
operation, a single CST unit, in a single pass-through of feedstream, 
processed 90 gallons of water containing more than 400 ppm of chromium, and 
reduced the contamination level to 0.49 ppm. This reduced level of 
contamination was below the federal guideline (5 ppm) for the unregulated 
discharge of water. The results of this test were verified by Artesian 
Laboratories, Inc., an independent testing laboratory. The Company has since 
completed additional on-site demonstrations of CST at the Port of Baltimore 
with similar results. Due to the success of such demonstrations, in February 
1997 the State of Maryland informed the Company that it will recommend 
including the CST process as an eligible technology in the bid specifications 
to remediate the groundwater at the Port of Baltimore. The Company believes 
that compliance with the federal guideline can be achieved either by 
refinement of chemical formulation or process procedure, by dilution of the 
processed water with a small amount of uncontaminated water, or by passing 
the processed water through a larger or supplemental CST unit. The Company 
believes that the same process is capable of achieving comparable results in 
the same time period on substantially greater volumes of contaminated water, 
either by increasing the flow of feedstream into the membrane, by configuring 
and utilizing a larger module, or by installing and operating additional 
modules. As indicated above, this demonstration was performed on limited 
quantities of process streams, and there can be no assurance that the same or 
similar results would or could be obtained on a larger scale. 
    

                                      37 
<PAGE>

   To speed its entry in this market, the Company intends to enter into 
collaborative joint working and marketing arrangements with established 
engineering and environmental service organizations which are expected to 
provide technical and professional expertise, market presence and 
credibility. Although the Company has entered into memorandums of 
understanding with several such companies, the Company has not to date 
entered into any definitive agreements or received any firm contract awards. 
See "-- Collaborative Working Arrangements." 

   Radionuclide/Mixed Waste Separation 

   In the United States, there are numerous sites operated or maintained by 
the Department of Energy ("DOE") and/or the Department of Defense at which 
there are present "mixed wastes" containing radionuclides intermingled with 
other hazardous wastes. These sites are also contaminated with other 
compounds associated with nuclear weapons, testing and energy. CST has been 
demonstrated to have significant capabilities in the separation of 
radionuclides such as cesium, technetium and rhenium, and the Company 
believes that such capabilities, although untested, extend to most of the 
other compounds found at such sites. The United States government estimates 
that potential government expenditures in this market could be between $234 
billion and $389 billion over the course of the next 75 years. 

   This element of the market is a significant subcategory of the general 
environmental remediation that can be undertaken with CST. In addition to low 
initial capital costs and low operational costs, CST has the advantage of 
cost-effectively separating both dissolved mixed waste and radionuclides, and 
allowing separate handling and disposal of both hazardous waste types. The 
Company anticipates pursuing this market area in collaboration with 
established engineering and environmental service organizations, who can 
provide technical and professional expertise, market presence and 
credibility. Neither the Company nor any of its collaborative partners have 
been awarded any contracts to use CST, and there can be no assurance as to 
whether or when any such contracts may be obtained. 

   In January 1997, the Company entered into a license agreement with 
Lockheed Martin, manager of Oak Ridge (the "Lockheed License Agreement"). 
Under the terms of the Lockheed License Agreement, the Company received the 
exclusive worldwide license, subject to a government use license, to use and 
develop the technology related to the separation of the radionuclides 
technetium and rhenium from mixed wastes containing radioactive materials. 
The Company also received under the Lockheed License Agreement the right to 
exploit the technology for other commercial applications. Pursuant to the 
Lockheed License Agreement, the Company made an initial cash payment of 
$50,000 upon the execution of the agreement and is obligated to pay, 
commencing in the third year of the Lockheed License Agreement, a royalty to 
Lockheed Martin of 2% of net sales (less allowances for returns, discounts, 
commissions, freight, and excise or other taxes) up to total net sales of 
$4,000,000 and 1% of net sales thereafter. In addition, the Company has 
agreed to guarantee Lockheed Martin, during the term of the Lockheed License 
Agreement, an annual minimum royalty of $15,000 commencing in the third year 
of the Lockheed License Agreement. The Lockheed License Agreement, which may 
be terminated at any time solely by the Company, has a term which will last 
until the end of the life of all patents or patentable claims described in or 
ultimately arising out of the provisional patent recently filed jointly by 
the Company and three of Dr. Kilambi's colleagues who worked with him at Oak 
Ridge, covering their inventions related to radionuclides. See "-- 
Intellectual Property" below. 

   Based on tests conducted at Oak Ridge since May 1994, the Company believes 
that this technology is capable of selectively extracting and recovering 
technetium, rhenium and other radioactive isotopes as a concentrated aqueous 
solution which can be reused in various scientific applications or disposed 
of by government-approved techniques including long-term storage. The 
Company believes that this technology can be used to remediate nuclear waste 
tanks stored at the DOE's atomic energy plants in Rocky Flats, Colorado, 
Idaho Falls, Idaho, Paducah, Kentucky, Weldon Springs, Missouri, Frenchman 
Flat, Nevada, Los Alamos, New Mexico, Aiken, South Carolina, Oak Ridge, 
Tennessee, Pantex, Texas and Hanford, Washington, and intends to pursue such 
opportunities. According to DOE sources, there are approximately 100 million 
gallons of mixed radioactive and hazardous chemical waste stored at these 
plants. 

   The DOE has reported that better methods of separating radionuclides could 
lead to reduced volumes of high-level waste and lower ongoing costs. 
Radionuclides in high-level wastes are a small fraction (.001% or less) 

                                      38 
<PAGE>

of DOE's waste volume. Each disposal canister for high-level waste is 
expected to cost approximately $1,000,000 to build and maintain. The Company 
believes that concentrating the radionuclides in these wastes could reduce 
the number of canisters needed by at least tenfold, and save significant sums 
in ongoing costs. The Company currently does not have, nor can there be any 
assurance that it will be awarded, any contract with the DOE to use its 
separation technology at DOE plants. 

PROPOSED MANUFACTURING OPERATIONS 

   The Company currently has a limited number of outside sources of supply 
for some strategic components used in CST, including chemicals, fibers and 
membrane casings. Business disruptions or financial difficulties of such 
suppliers, or raw material shortages or other causes beyond the Company's 
control, could adversely affect the Company by increasing their cost of goods 
sold or reducing the availability of such components. The use of outside 
suppliers also entails risks of quality control and disclosure of proprietary 
information. 

   
   The Company has leased a new facility of approximately 20,000 square feet 
near Atlanta, Georgia, which it began occupying in March 1997 and will 
comprise the Company's administrative offices, research and testing 
laboratories and CST manufacturing plant. It is anticipated that 
approximately $2,000,000 of the net proceeds of this Offering will be 
required with respect to leasing such facility and related leasehold 
improvements. Additionally, it is anticipated that approximately $2,500,000 
of the net proceeds of this Offering will be required to purchase the 
equipment necessary to manufacture the modules and produce the proprietary 
chemicals used in CST. Prior to the Company's facility becoming operational 
for manufacturing, the Company anticipates spending approximately $1,200,000 
of the net proceeds of this Offering to purchase CST components for use in 
connection with initial demonstrations and/or installations of CST at 
customer sites. Once the plant is fully operational, the Company expects to 
benefit from greater quality control, increased assurance of product 
availability, and greater protection of proprietary information and 
technology. See "Risk Factors -- Dependence on Strategic Components" and from 
suppliers; Limited Manufacturing Operations "-- Unpredictability of Patent 
Protection and Proprietary Technology" and "Use of Proceeds." 
    

COLLABORATIVE WORKING ARRANGEMENTS 

   As of the date of this Prospectus, the Company has entered into 
memorandums of understanding with Teledyne Brown and Sverdrup for various 
uses and applications of CST, principally in connection with large-scale 
clean-ups of governmental facilities. 

   
   Pursuant to separate memorandums of understanding with each of Teledyne 
Brown and Sverdrup, the Company and each of Teledyne Brown and Sverdrup, 
respectively, have agreed to negotiate, on a non-exclusive basis, the 
formation of one or more mutually agreeable business arrangements concerning 
the marketing, application and commercialization of CST. In addition to 
conducting due diligence with respect to each company's technology in 
accordance with the confidentiality provisions contained in the memorandums 
of understanding, the Company and each of Teledyne Brown and Sverdrup, 
respectively, are currently negotiating the scope, covered applications and 
geographical territory encompassed by the proposed joint marketing and 
commercialization activities. It is expected that the Company's relationship 
with Teledyne Brown will focus on Department of Energy sites such as Hanford, 
Washington and Mound, Ohio, and that the Company's initial opportunities with 
Sverdrup will focus on Department of Defense sites such as Cape Cod, 
Massachusetts. In the event a definitive agreement is not entered into by the 
Company and Teledyne Brown or Sverdrup, respectively, on or before August 31, 
1997, such memorandum of understanding may be terminated by either company 
upon written notice and, except for the survival of the confidentiality 
provisions, without any further liability to the other company. As of the 
date of the Prospectus, the Company has not determined the amount of net 
proceeds of this Offering to be applied to these or any other particular 
proposed collaborative working arrangement. See "Use of Proceeds." Although 
the Company believes that it will enter into definitive joint working 
agreements with Teledyne Brown, Sverdrup and other potential collaborative 
partners, there can be no assurance that these memorandums of understanding 
or other future discussions will result in any definitive joint ventures or 
related agreements, or, even if such agreements are executed, that the 
Company and its prospective collaborators will be awarded any projects that 
will ultimately result in revenues and earnings for the Company.

CFC SERVICES AGREEMENT 

   Effective upon completion of this Offering, the Company will enter into a 
services agreement (the "Services Agreement") with Commodore CFC 
Technologies, Inc., a wholly-owned subsidiary of Applied ("CFC 
Technologies"), which has developed and patented a process which, based on 
test applications of limited quantities of chlorofluorocarbons ("CFCs"), may 
be able to separate mixtures of refrigerants so that they can be returned to 
productive use at purity levels meeting industry standards. Pursuant to the 
Services Agreement, the Company will provide advice, assistance and guidance, 
and, where necessary, personnel to implement the same, in connection with, 
among others, administrative, financial and related matters, product design, 
development and promotion, and marketing, sales and related operations to CFC 
Technologies in connection with its business and operations in exchange for 
which the Company will be paid an annual fee equal to 75% of the net income 
of CFC Technologies, if any, and reimbursement of expenses incurred in 
furnishing such services. The Services Agreement may be terminated by either 
party at any time upon not less than 90 days' prior notice. 

GOVERNMENT REGULATION 

   The Company and its customers are required to comply with a number of 
federal, state and local laws and regulations in the areas of safety, health 
and environmental controls including, without limitation, RCRA and OSHA, 
which may require the Company, its prospective working partners or its 
customers to obtain permits or approvals to utilize CST and related equipment 
on certain job sites. In addition, if the Company begins to market CST 
internationally, the Company will be required to comply with laws and 
regulations and, when applicable, obtain permits or approvals in those other 
countries. There is no assurance that such required permits and approvals 
will be obtained. Furthermore, particularly in the environmental remediation 
market, the Company may be required to conduct performance and operating 
studies to assure government agencies that CST and its by-products do not 
pose environmental risks. There is no assurance that such studies, if 
successful, will not be more costly or time-consuming than anticipated. 
Further, if new environmental legislation or regulations are enacted or 
existing legislation or regulations are amended, or are interpreted or 
enforced differently, the Company, its prospective working partners and/or 
its customers may be required to meet stricter standards of operation and/or 
obtain additional operating permits or approvals. 

ENVIRONMENTAL MATTERS 

   The Company's operations, as well as the use of specialized technical 
equipment by its customers, are subject to numerous federal, state and local 
regulations relating to the storage, handling and transportation of certain 
regulated materials. Although the Company's role is generally limited to the 
leasing of its specialized technical equipment for use by its customers, 
there is always the risk of the mishandling of such materials or 
technological or equipment failures, which could result in significant claims 
against the Company. Any such claims against the Company could materially 
adversely affect the Company's business, financial condition and results of 
operations. 

   The Company maintains environmental liability insurance with limits of 
$1,000,000 per occurrence and $1,000,000 in the aggregate. The Company may be 
required to obtain environmental liability insurance in greater amounts in 
the future as CST is commercialized. There can be no assurance that such 
insurance will provide coverage against all claims, and claims may be made 
against the Company (even if covered by the Company's insurance policy) for 
amounts substantially in excess of applicable policy limits. Any such event 
could have a material adverse effect on the Company's business, financial 
condition and results of operations. 

INTELLECTUAL PROPERTY 

   The basic principles underlying the CST technology were developed by 
Srinivas Kilambi, Ph.D., the Company's Vice President - Technology. Effective 
February 29, 1996, pursuant to an assignment of technology agreement between 
the Company and Dr. Kilambi, the Company acquired rights to the CST 
technology from Dr. Kilambi, together with associated patent rights, 
confidential know-how and other property rights created or obtained by Dr. 
Kilambi, whether then existing or thereafter created, relating to the 
construction, design, development and exploitation of the processes, 
equipment and technology related to CST and any other product or development 
resulting from the acquired patent rights. 

                                      40 
<PAGE>

   In consideration for his assignment of the CST technology, the Company 
transferred to Dr. Kilambi 200,000 shares of common stock of Commodore, which 
had been contributed to the Company by Commodore to effect the transaction, 
and the Company agreed to pay Dr. Kilambi a royalty through December 3, 2002 
equal to 2% of its revenues actually received and attributed to the 
commercial application of the acquired technology, except for applications 
related to the radionuclides technetium and rhenium, for which Dr. Kilambi is 
entitled to receive a royalty of .66% of net sales (less allowances for 
returns, discounts, commissions, freight and excise or other taxes). See 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations -- Liquidity and Capital Resources" and "Certain Relationships and 
Related Transactions -- Organization and Capitalization of the Company." 

   The Company has filed one United States utility patent application and two 
United States provisional patent applications covering the principal features 
of its CST technology. One provisional patent application covers the joint 
inventions of Dr. Kilambi and Lockheed Martin, and a corresponding utility 
patent application containing the specific patent claims is expected to be 
filed in the near future. The Company may also pursue foreign patent 
protection where it deems appropriate. 

   The Company's liquid membrane technology patent applications are based on 
the selective combination of different known solvents, supports, diluents, 
carriers and other components to separate a variety of metals, chemicals and 
other targeted substances. While the Company believes that its technology 
covers all separation applications, third parties may have developed, or may 
subsequently assert claims to, certain of these solvents, supports, diluents, 
carriers or other components for one or more specific applications. In such 
event, the Company may need to acquire licenses to, or to contest the 
validity of, issued or pending patents or claims of third parties. 

   To protect its trade secrets and the unpatented proprietary information in 
its development activities, the Company requires its employees, consultants 
and contractors to enter into agreements providing for the confidentiality 
and the Company's ownership of such trade secrets and other unpatented 
proprietary information originated by such persons while in the employ of the 
Company. The Company also requires potential collaborative partners to enter 
into confidentiality and non-disclosure agreements. 

   There can be no assurance that any patents which may hereafter be 
obtained, or any of the Company's confidentiality and non-disclosure 
agreements, will provide meaningful protection of the Company's confidential 
or proprietary information in the case of unauthorized use or disclosure. In 
addition, there can be no assurance that the Company will not incur 
significant costs and expenses, including the costs of any future litigation, 
to defend its rights in respect of any such intellectual property. 

COMPETITION 

   The most common alternative methods for metals separation from solubilized 
process streams presently include ion exchange, reverse osmosis, 
precipitation, ultrafiltration and chromatography. The Company believes that 
most of these methods have certain drawbacks, including lack of selectivity 
in the separation process, inability to handle certain metals in the process 
streams, and the creation of sludges and other harmful by-products which 
require further post-treatment prior to disposal. For example, reverse 
osmosis and ultrafiltration are incapable of separating chrome and chromium 
materials from wastewater streams, and precipitation results in the 
production of sludge which requires dewatering, drying and disposal in a 
landfill. Certain of these other technologies also entail long process times, 
and are relatively expensive. 

   By contrast, CST is capable of handling a broad range of compounds in a 
faster and relatively inexpensive manner. Furthermore, the by-products of the 
CST process consist primarily of wastewater, which can be discharged as 
normal wastewater effluent, and to a substantially lesser extent and in only 
rare circumstances, materials requiring landfill disposal. 

   Separation technologies are currently utilized by a wide variety of 
domestic and international companies, including several large companies 
having substantially greater financial and other resources than the Company. 
Although the Company believes that CST has substantial advantages over all 
other known separation technologies, any one or more of the Company's 
competitors, or other enterprises not presently known, may develop 
technologies which are superior to CST. To the extent the Company's 
competitors are able to offer comparable 

                                      41 
<PAGE>

services at lower prices or of higher quality, or more cost-effective 
alternatives, the Company's ability to compete effectively could be 
materially adversely affected. The Company believes that its ability to 
compete in both the commercial and governmental sectors is dependent upon CST 
being a superior, more cost-effective method to achieve separation and/or 
recovery of a variety of materials in varying amounts and configurations. In 
the event that the Company is unable to demonstrate that CST is a technical 
and cost-effective alternative to other separation technologies on a 
commercial scale, the Company may not be able to successfully compete. 

RESEARCH AND DEVELOPMENT 

   
   The Company continues to perform research and development activities with 
respect to CST, utilizing its internal technical staff as well as independent 
consultants. Such activities have to date been entirely Company-sponsored. 
Research and development expenditures were $412,340 and $462,420 for the six 
month period ended December 31, 1996 and the period from November 15, 1995 
(date of inception) to December 31, 1996, respectively. 
    

   The Company intends to expand its research and development efforts 
following this Offering. In addition to conducting ongoing tests, 
demonstrations and enhancements of CST, the Company's efforts are expected to 
focus on the optimization of performance and design for module manufacturing, 
development of new carriers and diluents, and investigation of additional 
process applications. The Company will use a portion of the net proceeds of 
this Offering for such ongoing development costs, which will include the 
hiring of additional personnel. See "Use of Proceeds." 

EMPLOYEES 

   As of December 31, 1996, the Company had 12 full-time employees, including 
five with advanced scientific degrees. The Company believes that it has been 
successful in attracting experienced and capable personnel. All of the 
Company's employees have entered into agreements with the Company requiring 
them not to disclose the Company's proprietary information, assigning to the 
Company all rights to inventions made during their employment, and 
prohibiting them from competing with the Company. The Company's employees are 
not represented by any labor union. The Company believes that relations with 
its employees are satisfactory. 

PROPERTIES 

   
   The Company currently leases approximately 7,000 square feet of space in 
Columbus, Ohio from an unaffiliated third party under a lease expiring on 
June 30, 1997, which the Company uses as its laboratory and administrative 
offices. The Company shares such space with Commodore and certain of its 
other subsidiaries. As of July 1, 1996, the Company pays an allocable share 
of the rent equal to $750 per month for such space. 

   The Company's principal executive offices are located in approximately 
1,000 square feet of office space in Vienna, Virginia under a lease expiring 
in December 1997. The Company pays approximately $5,000 per month for rent 
and related office support services. Such office also serves as the principal 
executive offices of Applied. The Company also maintains offices located in 
approximately 2,000 square feet of office space in New York, New York, which 
also serves as the principal executive offices of Commodore, Applied, certain 
of their affiliates, and Bentley J. Blum and Paul E. Hannesson, directors of 
each of the Company, Commodore and Applied. The Company does not pay any rent 
with respect to such offices. An allocable share of such rent would not be 
material. See "Certain Relationships and Related Transactions -- Offices." 

   The Company has leased a new facility of approximately 20,000 square feet 
near Atlanta, Georgia, which it began occupying in March 1997 and which will 
comprise the Company's administrative offices, research and testing 
laboratories and CST manufacturing plant. See "Use of Proceeds." Upon 
commencement of full occupancy at such facility, the Company, together with 
Commodore, may elect to terminate the existing lease in Columbus, Ohio.

STOCK OPTIONS 

   On September 5, 1996, Commodore (as sole stockholder of the Company) 
approved the Company's 1996 Stock Option Plan, as previously adopted by the 
Company's Board of Directors (the "Plan"), pursuant to which officers, 
directors, and/or key employees and/or consultants of the Company can receive 
incentive stock options and non-qualified stock options to purchase up to an 
aggregate of 1,350,000 shares of the Company's Common Stock (of which no more 
than 1,147,500 shares may be issued pursuant to non-qualified stock options). 
On September 5, 1996, December 18, 1996 and January 27, 1997, the Company's 
Board of Directors awarded, effective upon completion of this Offering, 
non-qualified stock options under the Plan to certain key executive officers 
entitling them to purchase an aggregate of 630,000 shares of Common Stock, 
all of which provide for an exercise price equal to the initial public 
offering price of the Common Stock, are exercisable at the rate of 20% of the 
number of options granted in each of calendar 1996 (1997 in the case of Mr. 
Houle) through 2000, inclusive, beginning on the closing date of this 
Offering and, unless exercised, expire on December 31, 2001 (subject to prior 
termination in accordance with the applicable stock option agreements). In 
addition, non-qualified options to purchase an aggregate of 136,689 shares of 
Common Stock were awarded, effective upon completion of this Offering, to 
members of the Board of Directors who are not employed or otherwise 
affiliated with the Company, all of which are exercisable at an exercise 
price equal to the initial public offering price of the Common Stock, are 
exercisable at the rate of 33 1/3 % of the number of options granted in each 
of calendar 1996 through 1998, inclusive, beginning on the closing date of 
this Offering, and, unless exercised, expire on December 31, 2001 (subject to 
prior termination in accordance with the applicable stock option agreements). 
The exercise price applicable to all outstanding stock options represents not 
less than 100% of the fair market value of the underlying Common Stock as of 
the date that such options were granted, as determined by the Board of 
Directors of the Company on the date that such options were granted. In 
December 1996 and January 1997, Applied, as purchaser of 100% of the capital 
stock of the Company, ratified the Plan and all issuances thereunder. 

   With respect to incentive stock options, the Plan provides that the 
exercise price of each such option must be at least equal to 100% of the fair 
market value of the Common Stock on the date that such option is granted (and 
110% of fair market value in the case of stockholders who, at the time the 
option is granted, own more than 10% of the total outstanding Common Stock), 
and requires that all such options have an expiration date not later than 
that date which is one day before the tenth anniversary of the date of the 
grant of such options (or the fifth anniversary of the date of grant in the 
case of 10% stockholders). However, with certain limited exceptions, in the 
event that the option holder ceases to be associated with the Company, or 
engages in or is involved with any business similar to that of the Company, 
such option holder's incentive options immediately terminate. Pursuant to the 
provisions of the Plan, the aggregate fair market value, determined as of the 
date(s) of grant, for which incentive stock options are first exercisable by 
an option holder during any one calendar year cannot exceed $100,000. 

   With respect to non-qualified stock options, the Plan requires that the 
exercise price of all such options be at least equal to 100% of the fair 
market value of the Common Stock on the date such option is granted, provided 
that non-qualified options may be issued at a lower exercise price (but in no 
event less than 85% of fair market value) if the net pre-tax income of the 
Company in the full fiscal year immediately preceding the date 

                                      47 
<PAGE>

of the grant of such option (the "Prior Year") exceeded 125% of the mean 
annual average net pre-tax income of the Company for the three fiscal years 
immediately preceding such Prior Year. Non-qualified options must have an 
expiration date not later than that date which is the day before the eighth 
anniversary of the date of the grant of the subject option. However, with 
certain limited exceptions, in the event that the option holder ceases to be 
associated with the Company, or engages in or becomes involved with any 
business similar to that of the Company, such option holder's non-qualified 
options immediately terminate. 

   The following table lists information on stock options granted to each of 
the Company's executive officers and directors and to all executive officers 
and directors as a group. All of such stock options were granted on September

EXECUTIVE BONUS PLAN 

   On September 5, 1996, the Company's Board of Directors established a 
five-year Executive Bonus Plan (the "Bonus Plan") to reward executive 
officers and other key employees based upon the Company achieving certain 
performance levels. Under the Bonus Plan, commencing with the Company's 1997 
fiscal year and for each of the four fiscal years thereafter, the Company 
will have discretion to award bonuses in an aggregate amount in each fiscal 
year equal to 1% of the Company's consolidated net revenues for such fiscal 
year, provided and on the condition that the Company achieves a consolidated 
net profit before taxes of not less than 5% of consolidated net sales in each 
year, and provided that the aggregate bonuses in each year (out of the 
maximum amount of 1% of annual net sales) shall not be in excess of the 
proportion by which the Company's consolidated net profit before taxes is 
greater than 5% of consolidated net sales but less than 15% of consolidated 
net sales. The Compensation Committee of the Board of Directors of the 
Company will determine the allocable amounts or percentages of the bonus pool 
which may be paid annually to participants. Bonuses under the Bonus Plan are 
not exclusive of other bonuses that may be awarded by the Board of Directors 
or the Compensation Committee from time to time. 

LIMITATION OF DIRECTORS' AND OFFICERS' LIABILITY AND INDEMNIFICATION 

   The Company has included in its Certificate of Incorporation and By-Laws 
provisions to (i) eliminate the personal liability of its directors and 
officers for monetary damages resulting from breaches of their fiduciary duty 
(provided that such provisions do not eliminate liability for breaches of the 
duty of loyalty, acts or omis-

sions not in good faith or which involve intentional misconduct or a knowing 
violation of law, violations under Section 174 of the Delaware General 
Corporation Law (the "Delaware Law"), or for any transaction from which the 
director and/or officer derived an improper personal benefit), and (ii) 
indemnify its directors and officers to the fullest extent permitted by the 
Delaware Law, including circumstances in which indemnification is otherwise 
discretionary. The Company believes that these provisions are necessary to 
attract and retain qualified persons as directors and officers.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS 

ORGANIZATION AND CAPITALIZATION OF THE COMPANY 

   The Company was organized in November 1995 as a wholly-owned subsidiary of 
Commodore. Effective February 29, 1996, pursuant to an assignment of 
technology agreement between the Company and Srinivas Kilambi, Ph.D., the 
Company's Vice President--Technology, the Company acquired rights to the CST 
technology from Dr. Kilambi. In consideration for such technology, the 
Company transferred to Dr. Kilambi 200,000 shares of common stock of 
Commodore, which had been contributed to the Company by Commodore to effect 
the transaction, and the Company agreed to pay Dr. Kilambi a royalty through 
December 3, 2002 equal to 2% of the Company's revenues actually received and 
attributed to the commercial application of the acquired technology, except 
for applications related to the radionuclides technetium and rhenium, for 
which Dr. Kilambi is entitled to receive a royalty of .66% of net sales (less 
allowances for returns, discounts, commissions, freight, and excise or other 
taxes). In exchange for Commodore's issuance of such shares to the Company, 
as well as Commodore's funding and support of the Company, the Company issued 
to Commodore 10,000,000 shares of Common Stock. See "Management's Discussion 
and Analysis of Financial Condition and Results of Operations -- Liquidity 
and Capital Resources" and "Business -- Intellectual Property." 

   Since the Company's inception, Commodore has financed the research and 
development activities of the Company through direct equity investments and 
loans to the Company. As of September 30, 1996, the Company's aggregate 
indebtedness to Commodore was approximately $408,000. As of December 2, 1996, 
$568,000 in additional funds had been advanced by Commodore to the Company. 
Commodore has agreed to contribute the entire amount of such intercompany 
debt to the Company's equity, without requirement of the issuance of any 
additional shares of capital stock. 

   Effective as of December 2, 1996, as part of a corporate restructuring to 
consolidate all of its current environmental technology businesses within 
Applied (its 69.3%-owned, publicly-traded subsidiary), Commodore transferred 
to Applied 100% of the capital stock of the Company and 100% of the capital 
stock of CFC Technologies, another subsidiary of Commodore. 

   
   In addition, Commodore assigned to Applied outstanding Company notes 
aggregating $976,200 at December 2, 1996, representing advances previously 
made by Commodore to the Company. Such advances have been capitalized by 
Applied prior to the date of this Offering as its Capital Contribution to the 
Company. In consideration for such transfers, Applied paid Commodore 
$3,000,000 in cash and, subject to any applicable stockholder approval and 
notification requirements, shall issue to Commodore a warrant expiring 
December 1, 2003 to purchase 7,500,000 shares of Applied common stock at an 
exercise price of $15.00 per share. 
    

LOAN AGREEMENT WITH COMMODORE 

   
   In the event the Over-allotment Option is exercised, the Company intends 
to enter into a two-year revolving credit agreement with Commodore. Pursuant 
to such agreement, the Company may lend the net proceeds, if any, from the 
exercise of the Over-allotment Option (estimated to be up to approximately 
$3,250,000) to Commodore for its working capital needs. Borrowings under the 
agreement will be secured by Commodore's pledge of 2,000,000 shares of 
Applied common stock held by it and will bear interest at the rate of 10% per 
annum, with interest payable quarterly on outstanding amounts. The principal 
balance outstanding will be due on the second anniversary of the date of such 
agreement. The Company's obligation to lend such funds to Commodore is 
subject to a number of conditions, including review by the Company of the 
proposed use of such funds by Commodore. See "Risk Factors -- Control by 
Principal Stockholder; Loan to Commodore," "Use of Proceeds" and 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations -- Liquidity and Capital Resources." 
    

OFFICES 

   
   The Company's principal executive offices are located in approximately 
1,000 square feet of office space in Vienna, Virginia under a lease expiring 
in December 1997. The Company pays approximately $5,000 per month 

                                      52 
    
<PAGE>

   
for rent and related office support services. Such office also serves as the 
principal executive offices of Applied. The Company also maintains offices 
located in approximately 2,000 square feet of office space in New York, New 
York, which also serves as the principal executive offices of Commodore, 
Applied, certain of their affiliates, and Messrs. Bentley J. Blum and Paul E. 
Hannesson, directors of each of the Company, Commodore and Applied. The 
Company does not pay any rent with respect to such offices. In addition, the 
Company currently shares facilities in Columbus, Ohio with Commodore and 
certain of its other subsidiaries. The Company pays an allocable share of 
rent equal to $750 per month for such space. See "Business - Properties." 

   The Company has leased a new facility of approximately 20,000 square feet 
near Atlanta, Georgia, which it began occupying in March 1997 and which will 
comprise the Company's administrative offices, research and testing 
laboratories and CST manufacturing plant. See "Use of Proceeds." Upon 
commencement of full occupancy at such facility, the Company, together with 
Commodore, may elect to terminate the existing lease in Columbus, Ohio. 
    

FUTURE TRANSACTIONS 

   In connection with the Offering, the Company's Board of Directors has 
adopted a policy whereby any future transactions between the Company and any 
of its subsidiaries, affiliates, officers, directors, principal stockholders 
or any affiliates of the foregoing will be on terms no less favorable to the 
Company than could reasonably be obtained in "arm's length" transactions with 
independent third parties, and any such transactions will also be approved by 
a majority of the Company's disinterested outside directors.

                          DESCRIPTION OF SECURITIES 

GENERAL 

   The Company is authorized by its Certificate of Incorporation to issue an 
aggregate of 50,000,000 shares of Common Stock, par value $.001 per share, 
and 5,000,000 shares of preferred stock, par value $.001 per share (the 
"Preferred Stock"), which Preferred Stock may be issued with such rights, 
designations and privileges (including redemption and voting rights) as the 
Board of Directors may, from time to time, determine. 

COMMON STOCK 

   Holders of the Common Stock are entitled to one vote per share and, 
subject to the rights of the holders of the Preferred Stock (discussed 
below), to receive dividends when and as declared by the Board of Directors, 
and to share ratably in the assets of the Company legally available for 
distribution in the event of the liquidation, dissolution or winding up of 
the Company. The Board of Directors may not declare dividends payable to 
holders of Common Stock unless and until all accrued cash dividends through 
the most recent past annual dividend payment date have been paid in full to 
holders of the Convertible Preferred Stock. Holders of the Common Stock do 
not have subscription, redemption or conversion rights, nor do they have any 
preemptive rights. In the event the Company were to elect to sell additional 
shares of its Common Stock following this Offering, investors in this 
Offering would have no right to purchase such additional shares. As a result, 
their percentage equity interest in the Company would be diluted. The shares 
of Common Stock offered hereby will be, when issued and paid for, fully-paid 
and not liable for further call or assessment. Holders of the Common Stock do 
not have cumulative voting rights, which means that the holders of more than 
half of the outstanding shares of Common Stock (subject to the rights of the 
holders of the Preferred Stock) can elect all of the Company's directors, if 
they choose to do so. In such event, the holders of the remaining shares 
would not be able to elect any directors. The Board is empowered to fill any 
vacancies on the Board. Except as otherwise required by the Delaware Law, all 
stockholder action is taken by vote of a majority of the outstanding shares 
of Common Stock voting as a single class present at a meeting of stockholders 
at which a quorum (consisting of a majority of the outstanding shares of the 
Company's Common Stock) is present in person or by proxy. 

PREFERRED STOCK 

   The Company is authorized by its Certificate of Incorporation to issue a 
maximum of 5,000,000 shares of Preferred Stock, in one or more series and 
containing such rights, privileges and limitations, including voting rights, 
conversion privileges and/or redemption rights, as may, from time to time, be 
determined by the Board of Directors of the Company. Preferred Stock may be 
issued in the future in connection with acquisitions, financings or such 
other matters as the Board of Directors deems to be appropriate. In the event 
that any such shares of Preferred Stock shall be issued, a Certificate of 
Designation, setting forth the series of such Preferred Stock and the 
relative rights, privileges and limitations with respect thereto, shall be 
filed with the Secretary of State of the State of Delaware. The effect of 
such Preferred Stock is that the Company's Board of Directors alone, within 
the bounds and subject to the federal securities laws and the Delaware Law, 
may be able to authorize the issuance of Preferred Stock which could have the 
effect of delaying, deferring or preventing a change in control of the 
Company without further action by the stockholders and may adversely affect 
the voting and other rights of holders of Common Stock. The issuance of 
Preferred Stock with voting and conversion rights may also adversely affect 
the voting power of the holders of Common Stock, including the loss of voting 
control to others. 

CONVERTIBLE PREFERRED STOCK 

   The issuance of 1,875,000 shares of Convertible Preferred Stock has been 
authorized by resolutions adopted by the Board of Directors and set forth in 
a Certificate of Designation, Preferences and Rights of 10% Senior 
Convertible Redeemable Preferred Stock filed with the Secretary of State of 
the State of Delaware, which contains the designations, rights, powers, 
preferences, qualifications and limitations of the Convertible Preferred 
Stock. Upon issuance, the shares of Convertible Preferred Stock offered 
hereby will be fully paid and non-assessable. 

                                      54 
<PAGE>

   
   Dividends. The holders of the Convertible Preferred Stock are entitled to 
receive if, when and as declared by the Board of Directors out of funds 
legally available therefor, cumulative dividends at the rate of $1.00 per 
share per annum, payable quarterly on the last business day of March, June, 
September and December of each year, commencing June 30, 1997 (each a 
"Dividend Payment Date"), to the holders of record as of a date, not more 
than 60 days prior to the Dividend Payment Date, as may be fixed by the Board 
of Directors. Dividends accrue from the first day of the year in which such 
dividend may be payable, except with respect to the first annual dividend 
which shall accrue from the date of issuance of the Convertible Preferred 
Stock. 

   Dividends on the Convertible Preferred Stock will accrue whether or not 
the Company has earnings, whether or not there are funds legally available 
for the payment of such dividends and whether or not such dividends are 
declared. Dividends accumulate to the extent they are not paid on the 
Dividend Payment Date to which they relate. Accumulated unpaid dividends will 
not bear interest. Under Delaware Law, the Company may declare and pay 
dividends or make other distributions on its capital stock only out of 
capital surplus, as defined in the Delaware Law. On December 31, 1996, the 
Company had available surplus of $981,200 (or $22,071,700 after giving effect 
to this Offering). The payment of dividends and any future operating losses 
will reduce such surplus of the Company, which may adversely affect the 
ability of the Company to continue to pay dividends on the Convertible 
Preferred Stock. In addition, no dividends or distributions may be declared, 
paid or made if the Company is or would be rendered insolvent by virtue of 
such dividend or distribution. 
    

   No dividends may be paid on any shares of capital stock ranking junior to 
the Convertible Preferred Stock (including the Common Stock) unless and until 
all accumulated and unpaid dividends on the Convertible Preferred Stock have 
been declared and paid in full. 

   Conversion. At the election of the holder thereof, each share of 
Convertible Preferred Stock will be convertible into Common Stock at any time 
on or after the date of issuance and prior to redemption at a conversion rate 
of 1.33 shares of Common Stock for each share of Convertible Preferred Stock 
(an effective conversion price of $7.50 per share or 125% of the initial 
public offering price per share of Common Stock) (the "Conversion Price"). 
The Conversion Price is subject to adjustment from time to time in the event 
of (i) the issuance of Common Stock as a dividend or distribution on any 
class of capital stock of the Company; (ii) the combination, subdivision or 
reclassification of the Common Stock; (iii) the distribution to all holders 
of Common Stock of evidences of the Company's indebtedness or assets 
(including securities, but excluding cash dividends or distributions paid out 
of earned surplus); (iv) the failure of the Company to pay a dividend on the 
Convertible Preferred Stock within 30 days of a Dividend Payment Date, which 
will result in each instance in a reduction of $.50 per share in the 
Conversion Price but not below $3.75 per share, or 50% of the initial per 
share Conversion Price of the shares of Common Stock issuable upon conversion 
of the Convertible Preferred Stock; or (v) the sale of Common Stock at a 
price, or the issuance of options, warrants or convertible securities with an 
exercise or conversion price per share, less than the lower of the then 
current Conversion Price or the then current market price of the Common Stock 
(except upon exercise of options outstanding on the date of this Prospectus 
and options thereafter granted to employees, officers, directors, 
stockholders or consultants pursuant to existing stock option plans). No 
adjustment in the Conversion Price will be required until cumulative 
adjustments require an adjustment of at least 5% in the Conversion Price. No 
fractional shares will be issued upon conversion, but any fractions will be 
adjusted in cash on the basis of the then current market price of the Common 
Stock. Payment of accumulated and unpaid dividends will be made upon 
conversion to the extent of legally available funds. The right to convert the 
Convertible Preferred Stock terminates on the date fixed for redemption. 

   In case of any consolidation or merger to which the Company is a party 
(other than a consolidation or merger in which the Company is the surviving 
party and the Common Stock is not changed or exchanged), or in case of any 
sale or conveyance of all or substantially all the property and assets of the 
Company, each share of Convertible Preferred Stock then outstanding will be 
convertible from and after such merger, consolidation or sale or conveyance 
of property and assets into the kind and amount of shares of stock or other 
securities and property receivable as a result of such consolidation, merger, 
sale or conveyance by a holder of the number of shares of Common Stock into 
which such share of Convertible Preferred Stock could have been converted 
immediately prior to such merger, consolidation, sale or conveyance. 

   
   Optional Cash Redemption. The Company may, at its option, redeem the 
Convertible Preferred Stock, in whole but not in part, upon 30 days prior 
written notice at any time after March  , 2000 at a redemption price 
    

                                      55 
<PAGE>

   
of $10.00 per share, plus accumulated and unpaid dividends, if the Market 
Price of the Common Stock (as defined below) equals or exceeds $11.25 per 
share for at least 20 consecutive trading days ending not more than 10 
trading days prior to the date of the notice of redemption. The term "Market 
Price" means the closing bid price as reported by the principal securities 
exchange on which the Common Stock is listed or admitted to trading or by 
Nasdaq or, if not traded thereon, the high bid price as reported by Nasdaq 
or, if not quoted thereon, the high bid price on the OTC Bulletin Board or in 
the National Quotation Bureau sheet listing for the Common Stock, or, if not 
listed therein, as determined in good faith by the Board of Directors. 

   In addition, the Company may, at its option, redeem the Convertible 
Preferred Stock in whole but not in part, at any time after March  , 2001 at 
the redemption prices set forth below, plus accumulated and unpaid dividends:

</TABLE>

   Provisions Relating to Optional Cash Redemption. Notice of redemption must 
be mailed to each holder of Convertible Preferred Stock to be redeemed at his 
last address as it appears upon the Company's registry books at least 30 days 
prior to the date fixed for redemption (the "Redemption Date"). On and after 
the Redemption Date, dividends will cease to accumulate on shares of 
Convertible Preferred Stock called for redemption. 

   On or after the Redemption Date, holders of Convertible Preferred Stock 
which have been redeemed shall surrender their certificates representing such 
shares to the Company at its principal place of business or as otherwise 
specified in the notice of redemption or exchange and thereupon either (i) 
the redemption price of such shares shall be payable to the order of, or (ii) 
the shares of Common Stock shall be issued to, the person whose name appears 
on such certificate or certificates as the owner thereof; provided, that a 
holder of Convertible Preferred Stock may elect to convert such shares into 
Common Stock at any time prior to the Redemption Date. 

   From and after the Redemption Date, all rights of the holders of redeemed 
shares shall cease with respect to such shares and such shares shall not 
thereafter be transferred on the books of the Company or be deemed to be 
outstanding for any purpose whatsoever. 

   Voting Rights. The holders of Convertible Preferred Stock are not entitled 
to vote, except as set forth below and as provided by applicable law. On 
matters subject to a vote by holders of Convertible Preferred Stock, the 
holders are entitled to one vote per share. 

   The affirmative vote of at least a majority of the shares of Convertible 
Preferred Stock, voting as a class, shall be required to authorize, effect or 
validate the creation and issuance of any class or series of stock ranking 
superior to or on parity with the Convertible Preferred Stock with respect to 
the declaration and payment of dividends or distribution of assets on 
liquidation, dissolution or winding-up. In the event that the Company has the 
right to redeem the Convertible Preferred Stock, no such vote is required if, 
prior to the time such class is issued, provision is made for the redemption 
of all shares of Convertible Preferred Stock and such Convertible Preferred 
Stock is redeemed on or prior to the issuance of such class. 

   In the event that the Company fails to pay any dividends for four 
consecutive quarterly dividend payment periods, the holders of the 
Convertible Preferred Stock, voting separately as a class, shall be entitled 
to elect one director. Such right will be terminated as of the next annual 
meeting of stockholders of the Company following payment of all accrued 
dividends. 

   Liquidation. In the event of any voluntary or involuntary liquidation, 
dissolution or winding-up of the Company, before any payment or distribution 
of the assets of the Company (whether capital or surplus), or the proceeds 
thereof, may be made or set apart for the holders of Common Stock or any 
stock ranking junior to Convertible Preferred Stock, the holders of 
Convertible Preferred Stock will be entitled to receive, out of the assets of 
the Company available for distribution to stockholders, a liquidating 
distribution of $10.00 per share, 

                                      56 
<PAGE>

plus any accumulated and unpaid dividends. If, upon any voluntary or 
involuntary liquidation, dissolution or winding up of the Company, the assets 
of the Company are insufficient to make the full payment of $10.00 per share, 
plus all accumulated and unpaid dividends on the Convertible Preferred Stock 
and similar payments on any other class of stock ranking on a parity with the 
Convertible Preferred Stock upon liquidation, then the holders of Convertible 
Preferred Stock and such other shares will share ratably in any such 
distribution of the Company's assets in proportion to the full respective 
distributable amounts to which they are entitled. 

   A consolidation or merger of the Company with or into another corporation 
or sale or conveyance of all or substantially all the property and assets of 
the Company will not be deemed to be a liquidation, dissolution or 
winding-up, voluntary or involuntary, of the Company for purposes of the 
foregoing. See " Conversion." 

   Miscellaneous. The Company is not subject to any mandatory redemption or 
sinking fund provision with respect to the Convertible Preferred Stock. The 
holders of the Convertible Preferred Stock are not entitled to preemptive 
rights to subscribe for or to purchase any shares or securities of any class 
which may at any time be issued, sold or offered for sale by the Company. 
Shares of Convertible Preferred Stock redeemed or otherwise reacquired by the 
Company shall be retired by the Company and shall be unavailable for 
subsequent issuance as any class of the Company's Preferred Stock. 

WARRANTS 

   The following is a brief summary of certain provisions of the Warrants. 
Reference is made to the actual text of the Warrant Agreement between the 
Company, the Representative and The Bank of New York (the "Warrant Agent"), a 
copy of which has been filed as an exhibit to the Registration Statement of 
which this Prospectus is a part, for a more complete description of the 
Warrants. See "Additional Information." 

   
   Exercise Price and Terms. Each Warrant entitles the registered holder 
thereof to purchase, at any time during the four year period commencing one 
year after the date of this Prospectus, one share of Common Stock at a price 
of $8.40 per share, subject to adjustment in accordance with the 
anti-dilution and other 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. No fractional shares will be issued upon the exercise of the 
Warrants. 
    

   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 sale by the Company 
of shares of its Common Stock or other securities convertible into Common 
Stock (exclusive of options and shares under the Plan, and other limited 
exceptions) at a price below the then-applicable exercise price of the 
Warrants. Additionally, an adjustment would 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 18 months after the date of this 
Prospectus, the Warrants are subject to redemption at $.10 per Warrant on 30 
days' prior written notice provided that the average closing sale price of 
the Common Stock equals or exceeds $18.00 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 

                                      57 
<PAGE>

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 continue. 

   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 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. No other modifications may be made to the 
Warrants, without 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. 

   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. 

SECTION 203 OF THE DELAWARE LAW 

   Section 203 of the Delaware Law prohibits a publicly-held Delaware 
corporation from engaging in a "business combination" with an "interested 
stockholder" for a period of three years after the date of the transaction in 
which the person became an interested stockholder, unless (i) prior to the 
date of the business combination, the transaction is approved by the board of 
directors of the corporation; (ii) upon consummation of the transaction which 
resulted in the stockholder becoming an interested stockholder, the 
interested stockholder owns at least 85% of the outstanding voting stock, or 
(iii) on or after such date, the business combination is approved by the 
board of directors and by the affirmative vote of at least 66 2/3 % of the 
outstanding voting stock that is not owned by the interested stockholder. A 
"business combination" includes mergers, asset sales and other transactions 
resulting in a financial benefit to the stockholder. An "interested 
stockholder" is a person, who, together with affiliates and associates, owns 
(or within three years, did own) 15% or more of the corporation's voting 
stock. 

TRANSFER AGENT AND REGISTRAR AND WARRANT AGENT 

   The Transfer Agent and Registrar for the Convertible Preferred Stock and 
the Common Stock and the Warrant Agent for the Warrants is The Bank of New 
York, 101 Barclay Street, New York, New York 10286. 

                                      58 
<PAGE>

                       SHARES ELIGIBLE FOR FUTURE SALE 

   
   Upon completion of this Offering, the Company will have 11,500,000 shares 
of Common Stock outstanding, of which (i) the 1,500,000 shares of Common 
Stock offered hereby, (ii) the 1,500,000 shares of Convertible Preferred 
Stock, (iii) the 3,000,000 Warrants, (iv) the maximum of 2,000,000 shares of 
Common Stock issuable upon conversion of the Convertible Preferred Stock and 
(v) the maximum of 3,000,000 shares of Common Stock issuable upon exercise of 
the Warrants will be transferable without restriction under the Securities 
Act. The other 10,000,000 outstanding shares of Common Stock, all of which 
are owned by Applied, 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 
Rule 144 as currently in effect, 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 Nasdaq 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 without regard to any of the 
limitations described above. 

   Subject to certain limitations on the aggregate offering price of a 
transaction and other conditions, Rule 701 generally may be relied upon with 
respect to the sale of shares purchased from the Company by its employees, 
directors, officers or consultants prior to the date of this Prospectus 
pursuant to written compensatory benefit plans such as the Plan and written 
contracts such as option agreements. Rule 701 is also available for sales of 
shares acquired by persons pursuant to the exercise of options granted prior 
to the effective date of this Prospectus, regardless of whether the option 
exercise occurs before or after the effective date of this Prospectus. 
Securities issued in reliance on Rule 701 are "restricted securities" within 
the meaning of Rule 144 and, beginning 90 days after the date of this 
Prospectus, may be sold by persons other than affiliates of the Company 
subject only to the manner of sale provisions of Rule 144 and by affiliates 
under Rule 144 without compliance with its one-year minimum holding period 
requirement. 
    

   Options granted under the Plan to purchase a total of 766,689 shares of 
Common Stock are currently outstanding, and options to purchase an additional 
583,311 shares of Common Stock are reserved for future issuance under the 
Plan. Of the options granted under the Plan, 171,563 of such options are 
currently exercisable, with the remaining outstanding options to become 
exercisable at the rate of 171,563 options in each of December 1997 and 1998, 
and 126,000 options in each of December 1999 and 2000. 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 and Rule 701. 

   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, the Convertible Preferred 
Stock and the Warrants prevailing from time to time. The Company and Applied, 
as well as all officers and directors of the Company and all holders of 
outstanding securities exercisable for or convertible into Common Stock 
(other than the Representative's Warrants), have agreed not to, directly or 
indirectly, issue, agree or offer to sell, sell, transfer, assign, 
distribute, grant an option for purchase or sale of, pledge, hypothecate or 
otherwise encumber or dispose of any beneficial interest in such securities 
for a period of 13 months following the date of this Prospectus without the 
prior written consent of the Representative. The sale or issuance, or the 
potential for sale or issuance, of Common Stock after such 13-month period 
could have an adverse impact on the market prices of the Convertible 
Preferred Stock, 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 Convertible Preferred 
Stock, the Common Stock and/or the Warrants. All of the shares of Convertible 
Preferred Stock to be outstanding will have been registered under the 
Securities Act. See "Underwriting."

                  CERTAIN FEDERAL INCOME TAX CONSIDERATIONS 

   In the opinion of Greenberg, Traurig, Hoffman, Lipoff, Rosen & Quentel, 
counsel to the Company, the material federal income tax consequences of 
acquiring, owning and disposing of the Convertible Preferred Stock, the 
Common Stock and the Warrants are as follows, subject to the qualifications 
set forth in the two immediately following paragraphs. 

   This discussion is based upon the Internal Revenue Code of 1986, as 
amended (the "Code"), Treasury Regulations, and Internal Revenue Service (the 
"IRS") rulings and judicial decisions now in effect, all of which are subject 
to change at any time by legislative, judicial or administrative action; any 
such changes could be retroactively applied in a manner that could adversely 
affect a holder of the Convertible Preferred Stock, Common Stock and/or 
Warrants. The following does not discuss all of the tax consequences that may 
be relevant to a purchaser in light of particular circumstances or to 
purchasers subject to special rules, such as foreign investors, retirement 
trusts, and life insurance companies. No information is provided with respect 
to foreign, state or local tax laws, estate or gift tax considerations, or 
other tax laws that may be applicable to particular categories of investors. 

   The discussion assumes that purchasers of the Convertible Preferred Stock, 
Common Stock and/or Warrants will hold the Convertible Preferred Stock, 
Common Stock and/or Warrants as a "capital asset" within the meaning of Code 
Section 1221. PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR TAX ADVISORS AS TO 
ANY FEDERAL, STATE, LOCAL AND FOREIGN OR OTHER TAX CONSIDERATIONS RELEVANT TO 
THEM. 

DIVIDENDS 

   
   Distributions with respect to the Convertible Preferred Stock and the 
Common Stock will be treated as dividends and taxable as ordinary income to 
the extent that the distributions are made out of the Company's current or 
accumulated earnings and profits. To the extent that a distribution is not 
made out of the Company's current or accumulated earnings and profits, the 
distribution will constitute a non-taxable return of capital reducing the 
holder's adjusted tax basis in the shares of Convertible Preferred Stock or 
Common Stock held and, to the extent the distribution exceeds such basis, 
will result in capital gain. At December 31, 1996, the Company had a deficit 
in accumulated earnings and profits. Accordingly, the treatment of 
distributions with respect to the Convertible Preferred Stock will be 
determined by the Company's earnings and profits, if any, subsequent to 
December 31, 1996. 
    

   Dividend income of individuals, certain closely held corporations and 
personal service corporations (as defined in Code Section 469(j) may not be 
offset by losses or credits from "passive activities," such as losses or 
credits incurred in connection with certain rental activities or the 
ownership of limited partnership interests. 

   Corporate stockholders will be eligible to claim a dividends-received 
deduction (currently 70% of the amount of the dividend for most corporate 
stockholders) with respect to distributions that are treated as dividends on 
the Convertible Preferred Stock and Common Stock in calculating their taxable 
income. 

   Under Code Section 246(c), the dividends-received deduction will not be 
available with respect to any dividend on the shares of Convertible Preferred 
Stock and Common Stock if such shares have been held for 45 days or less (or 
90 days or less if the holder of the shares of Convertible Preferred Stock 
received dividends with respect to the shares of Convertible Preferred Stock 
which are attributable to a period or periods aggregating in excess of 366 
days). The holding period of the shares of Convertible Preferred Stock for 
this purpose is determined in accordance with certain specific rules set 
forth in Code Section 246(c), which reduces the holding period for any period 
where the holder's risk of loss, as to such stock, is diminished by certain 
arrangements, such as the holding of an option to sell the same, or 
substantially identical, securities. Regulations issued on May 26, 1993 also 
reduce the holding period for any period in which a holder of Convertible 
Preferred Stock has outstanding a short sale of Common Stock. 

   Code Section 246A provides a further restriction on the availability of 
the dividends-received deduction on the shares of Convertible Preferred Stock 
and Common Stock if the shares are classified as "debt-financed portfolio 
stock." The shares of Convertible Preferred Stock will be classified as 
debt-financed portfolio stock when 

                                      60 
<PAGE>

the holder incurs indebtedness directly attributable to the investment in the 
shares of Convertible Preferred Stock. In that event, the dividends-received 
deduction would be reduced to take into account the average amount of such 
indebtedness. Also, the United States Treasury Department is authorized to 
issue regulations that (i) would reduce the interest deductions attributable 
to indebtedness in certain cases in which the obligor of such indebtedness is 
a person other than the recipient of the dividend, and (ii) would provide 
that any reduction in the dividends-received deduction cannot exceed the 
amount of any interest deduction allocable to such dividend. 

   A corporate shareholder will be required to reduce its basis in shares of 
the Convertible Preferred Stock and Common Stock (but not below zero) by the 
amount of any "extraordinary dividend" which is not taxed because of the 
dividends-received deduction if such holder is not considered to have held 
such stock for more than two years before the "dividend announcement date," 
within the meaning of Code Section 1059. The amount, if any, by which such 
reduction exceeds the corporate shareholder's basis in such shares will be 
treated as gain on the subsequent sale or disposition of the stock. With 
respect to the Convertible Preferred Stock, an "extraordinary dividend" would 
be a dividend that (i) equals or exceeds 5% of the holder's adjusted basis in 
the Convertible Preferred Stock or 10% in the Common Stock (treating all 
dividends having ex-dividend dates within an 85-day period as a single 
dividend) or (ii) exceeds 20% of the holder's adjusted basis in the stock 
(treating all dividends having ex-dividend dates within a 365-day period as a 
single dividend). If an election is made by the holder, under certain 
circumstances the fair market value of the stock as of the day before the 
ex-dividend date may be substituted for the holder's basis in applying these 
tests. An "extraordinary dividend" would also include any amount treated as a 
dividend in the case of a redemption of the Convertible Preferred Stock and 
the Common Stock that is non-pro rata as to all shareholders, without regard 
to the period the holder held the stock. 

   Special rules apply with respect to "qualified preferred dividends." A 
qualified preferred dividend is any fixed dividend payable with respect to 
preferred stock which (i) provides for fixed preferred dividends payable no 
less often than annually and (ii) is not in arrears as to dividends when 
acquired, provided the actual rate of return as determined under Section 
1059(e) (3) of the Code, on such stock does not exceed 15%. Where a qualified 
preferred dividend exceeds the 5% or 20% limitation described above, (1) the 
extraordinary dividend rules will not apply if the taxpayer holds the stock 
for more than five years, and (2) if the taxpayer disposes of the stock 
before it has been held for more than five years, the aggregate reduction in 
basis will not exceed the excess of the qualified preferred dividends paid on 
such stock during the period held by the taxpayer over the qualified 
preferred dividends which would have been paid during such period on the 
basis of the stated rate of return as determined under Section 1059(e) (3) of 
the Code. The length of time that a taxpayer is deemed to have held stock for 
purposes of the extraordinary dividend rules is determined under principles 
similar to those applicable for purposes of the dividends-received deduction 
discussed above. 

   A corporate holder may be required to include in determining its 
alternative minimum taxable income an amount equal to a portion of any 
dividends-received deduction allowed in computing regular taxable income. 

   Under certain circumstances, the operation of the conversion price 
adjustment provisions of the Convertible Preferred Stock may result in the 
holders being deemed to have received a constructive distribution, which may 
be taxable as a dividend, even though the holders do not actually receive 
cash or property. 

REDEMPTION PREMIUM 

   If the redemption price of preferred stock that is subject to optional 
redemption by the issuer exceeds the issue price and if such excess is not 
considered "reasonable," the entire amount of the redemption premium will be 
treated as being distributed to the holders of such stock, taxable as 
described above, on an economic accrual basis over the period from issuance 
of the preferred stock until the date the stock is first redeemable. A 
premium is considered to be reasonable if it is in the nature of a penalty 
for a premature redemption and if such premium does not exceed the amount 
which the issuer would be required to pay for such redemption right under 
market conditions existing at the time of issuance of the preferred stock. If 
the redemption premium payable on the Convertible Preferred Stock is 
considered unreasonable under the foregoing rules, a holder of the 
Convertible Preferred Stock would take the amount of such premium into income 
over the period during which the stock cannot be called for redemption under 
an economic accrual method. The Revenue Reconciliation Act of 1990 

                                      61 
<PAGE>

authorized the Treasury Department to promulgate new regulations regarding 
the federal income tax treatment of redemption premiums with respect to 
preferred stock. No such regulations have been issued and no assurance can be 
given as to the treatment of the redemption premium with respect to the 
Convertible Preferred Stock under any such regulations. 

CONVERSION 

   
   Conversion of the Convertible Preferred Stock into Common Stock will not 
result in the recognition of gain or loss (except with respect to cash 
received in lieu of fractional shares). The holder's adjusted tax basis in 
the Common Stock received upon conversion would be equal to the holder's tax 
basis in the shares of Convertible Preferred Stock converted, reduced by the 
portion of such basis allocable to the fractional share interest exchanged 
for cash. The holding period for the Common Stock received upon conversion 
would include the holding period of the Convertible Preferred Stock 
converted. The tax basis for the Convertible Preferred Stock will equal its 
cost, which is $10.00 per share at the initial public offering price, 
assuming the allocation of the purchase price between the Convertible 
Preferred Stock and the Warrants included in the Preferred Units is 
respected. See "-- Warrants" below. 
    

OPTIONAL CASH REDEMPTION 

   
   In the event the Company exercises its right to redeem the Convertible 
Preferred Stock the surrender of the Convertible Preferred Stock for the 
redemption proceeds by the holders will be treated as a sale or exchange and 
the surrendering holder will recognize capital gain or loss equal to the 
difference between the redemption proceeds (other than proceeds attributable 
to declared but unpaid dividends, which will be taxed as dividends as 
described above) and the holder's adjusted tax basis in the Convertible 
Preferred Stock, provided the redemption (1) results in a "complete 
termination" of the holder's stock interest in the Company (inclusive of any 
Common Stock owned) under Section 302(b)(3) of the Code, (2) is 
"substantially disproportionate" with respect to the holder under Section 
302(b)(2) of the Code, (3) is "not essentially equivalent to a dividend" with 
respect to the holder under Section 302(b)(1) of the Code, or (4) is from a 
noncorporate holder in partial liquidation of the Company under Section 
302(b)(4) of the Code. The constructive ownership rules of the Code must be 
taken into consideration in determining whether any of these tests has been 
met. If a redemption of the Convertible Preferred Stock does not meet any of 
these tests, then the gross proceeds received would be treated as a 
distribution taxable to the holder in the manner described under "Dividends" 
above. 
    

DISPOSITION 

   Except as described above, the holder of any of the Convertible Preferred 
Stock or Common Stock will recognize gain or loss upon the sale, exchange, 
redemption, retirement or other disposition of such securities measured by 
the difference between (a) the amount of cash and the fair market value of 
property received and (b) the holder's adjusted tax basis in the security 
disposed of. Any gain or loss on such sale, exchange, redemption, retirement 
or other disposition will be capital gain provided the security disposed of 
is held as a capital asset and will be long-term capital gain if the holding 
period exceeds one year. For corporate taxpayers, long-term capital gains 
are taxed at the same rate as ordinary income. For individual taxpayers, net 
capital gains (the excess of the taxpayer's net long-term capital gains over 
his net short-term capital losses) are subject to a maximum tax rate of 28%. 
The deductibility of capital losses are restricted and, in general, may only 
be used to reduce capital gains to the extent thereof. However, individual 
taxpayers may deduct $3,000 of capital losses in excess of their capital 
gains. Capital losses which cannot be utilized because of the aforementioned 
limitation are, for corporate taxpayers carried back three years and, in most 
circumstances, carried forward for five years; for individual taxpayers, 
capital losses may only be carried forward but without a time limitation. 

BACKUP WITHHOLDING 

   A holder of any of the Convertible Preferred Stock or Common Stock may be 
subject to backup withholding at the rate of 31% with respect to dividends 
thereon unless such holder (a) is a corporation or comes within certain other 
exempt categories and, when required, demonstrates this fact, or (b) provides 
a correct taxpayer identification number, certifies as to no loss of 
exemption from backup withholding and otherwise complies with applicable 
requirements of the backup withholding rules. A holder who does not provide 
the Company with a 

                                      62 
<PAGE>

correct taxpayer identification number may be subject to penalties imposed by 
the IRS. Any amount paid as backup withholding will be creditable against the 
holder's Federal income tax liability. Holders should consult their tax 
advisors regarding their qualification for exemption from backup withholding 
and the procedure for obtaining any applicable exemption. 

WARRANTS 

   
   A holder's basis in the Warrants will be equal to the purchase price paid 
therefor. However, there can be no assurance that the Internal Revenue 
Service will not allocate the aggregate purchase price for such securities in 
a different manner than as set forth on the cover page of this Prospectus for 
purposes of determining the respective adjusted bases for the Convertible 
Preferred Stock, Common Stock and/or Warrants of a purchaser, if any or all 
of such securities are purchased. 
    

   Upon a sale or exchange of the Warrants (including the receipt of cash in 
lieu of a fractional share of Common Stock issuable upon exercise of the 
Warrants), a holder of the Warrants will recognize capital gain or loss equal 
to the difference between the amount realized upon such sale or exchange and 
the holder's basis in the Warrants (as determined above). Such gain or loss 
will be long-term if, at the time of the sale or exchange, the Warrants were 
held for more than one year. Adjustments to the exercise price or conversion 
ratio, or the failure to make adjustments, may result in the receipt of a 
constructive dividend by the holder. 

   Upon exercise of the Warrants, a holder's tax basis in the Common Stock 
acquired upon such exercise will be equal to its tax basis in the Warrants 
plus the exercise price of the Warrants. The holding period with respect to 
such Common Stock will commence on the date of exercise. If the Warrants 
expire without being exercised, a holder will have a capital loss equal to 
its tax basis in the Warrants as if the Warrants had been sold on such date 
for no consideration.

   The Underwriters named below (the "Underwriters"), for whom National 
Securities Corporation is acting as representative (in such capacity, the 
"Representative"), have severally agreed, subject to the terms and conditions 
of the Underwriting Agreement (the "Underwriting Agreement"), to purchase 
from the Company and the Company has agreed to sell to the Underwriters on a 
firm commitment basis, the respective number of shares of Convertible 
Preferred Stock, shares of Common Stock and Warrants set forth opposite their

</TABLE>

   The Underwriters are committed to purchase all the shares of Convertible 
Preferred Stock, shares of Common Stock and Warrants offered hereby, if any 
of such Securities are purchased. The Underwriting Agreement provides that 
the obligations of the several Underwriters are subject to conditions 
precedent specified therein. 

   The Company has been advised by the Representative that the Underwriters 
propose initially to offer the Securities to the public at the initial public 
offering prices set forth on the cover page of this Prospectus and to certain 
dealers at such prices less concessions not in excess of $   per share of 
Convertible Preferred Stock, $   per share of Common Stock and $   per 
Warrant. Such dealers may reallow a concession not in excess of $   per share 
of Convertible Preferred Stock, $   per share of Common Stock and $   per 
Warrant to certain other dealers. After the commencement of the Offering, the 
public offering price, concession and reallowance may be changed by the 
Representative. 

   The Representative has informed the Company that it does not expect sales 
to discretionary accounts by the Underwriters to exceed five percent of the 
Securities offered hereby. 

   The Company has agreed to indemnify the Underwriters against certain 
liabilities, including liabilities under the Securities Act. The Company has 
also agreed to pay to the Representative a non-accountable expense allowance 
equal to 3% of the gross proceeds derived from the sale of the Securities 
underwritten. 

   The Company has granted to the Underwriters an over-allotment option, 
exercisable during the 45-day period from the date of this Prospectus, to 
purchase from the Company up to 225,000 additional shares of Convertible 
Preferred Stock, up to 225,000 additional shares of Common Stock and/or up to 
450,000 additional Warrants, at the initial public offering prices per share 
of Convertible Preferred Stock, per share of Common Stock and per Warrant, 
respectively, offered hereby, less underwriting discounts and the 
non-accountable expense allowance. Such option may be exercised only for the 
purpose of covering over-allotments, if any, incurred in the sale of the 
Securities offered hereby. To the extent such option is exercised in whole or 
in part, each Underwriter will have a firm commitment, subject to certain 
conditions, to purchase the number of the additional Securities proportionate 
to its initial commitment. 

   All officers, directors and stockholders of the Company and all holders of 
any options, warrants or other securities convertible, exercisable or 
exchangeable for Common Stock have agreed not to, directly or indirectly, 
offer, agree or offer to sell, sell, transfer, assign, encumber, grant an 
option for the purchase or sale of, pledge or otherwise dispose of any 
beneficial interest in such securities for a period of 13 months following 
the date of this Prospectus without the prior written consent of the 
Representative. An appropriate legend shall be marked on the face of 
certificates representing all such securities. 

   The Company has agreed not to, without the prior written consent of the 
Representative, issue, sell, agree or offer to sell, grant an option for the 
purchase or sale of, or otherwise transfer or dispose of any of its 
securities for a period of 13 months following the effective date of the 
Registration Statement of which this Prospectus is a part, except pursuant to 
the conversion of the Convertible Preferred Stock, the exercise of the 
Warrants and the exercise of those options existing on the date of this 
Prospectus. 

                                      64 
<PAGE>

   
   In connection with this Offering, the Company has agreed to sell to the 
Representative, for $.0001 per warrant, warrants to purchase from the Company 
up to 150,000 shares of Convertible Preferred Stock, 150,000 shares of Common 
Stock and/or 300,000 Warrants (the "Representative's Warrants"). The 
Representative's Warrants are initially exercisable at a price of $12.00 per 
share of Convertible Preferred Stock [120% of the initial public offering 
price per share of Convertible Preferred Stock], $7.20 per share of Common 
Stock [120% of the initial public offering price per share of Common Stock] 
and $.12 per Warrant [120% of the initial public offering price per Warrant], 
for a period of four years, commencing one year after the date of this 
Prospectus and are restricted from sale, transfer, assignment or 
hypothecation for a period of 12 months from the date of this Prospectus, 
except to officers of the Representative. The Representative's Warrants 
provide for adjustment in the number of securities issuable upon the exercise 
thereof as a result of certain subdivisions and combinations of the Common 
Stock. The Representative's Warrants grant to the holders thereof certain 
rights of registration for the securities issuable upon exercise thereof. 

   The Company has agreed for a period of five years after the date of this 
Prospectus, if requested by the Representative, to use its best efforts to 
nominate for election to the Company's Board of Directors one person 
designated by the Representative. In addition, the Representative may also 
designate a person to receive all notices of meetings of the Company's Board 
of Directors and all other correspondence and communications sent by the 
Company to its Board of Directors and to attend all such meetings of the 
Company's Board of Directors. The Company has agreed to reimburse designees 
of the Representative for their out-of-pocket expenses incurred in connection 
with their attendance of meetings of the Company's Board of Directors. 
    

   Prior to this Offering, there has been no public market for the 
Securities. Consequently, the initial public offering prices of the 
Securities and the terms of the Convertible Preferred Stock have been 
determined by negotiation between the Company and the Representative and do 
not necessarily bear any relationship to the Company's asset value, net 
worth, or other established criteria of value. The factors considered in such 
negotiations (without one factor being materially more important than 
another) were prevailing market conditions, the history of and prospects for 
the industry in which the Company competes, an assessment of the Company's 
management and technology, the prospects of the Company, its capital 
structure, Commodore's ownership interest in the Company, the market for 
initial public offerings and market prices of similar securities of 
comparable publicly-traded companies. 

   
   Upon the exercise of any Warrants more than one year after the date of 
this Prospectus, which exercise was solicited by the Representative, and to 
the extent not inconsistent with the guidelines of the National Association 
of Securities Dealers, Inc. and the Rules and Regulations of the Securities 
and Exchange Commission (the "Commission"), the Company has agreed to pay the 
Representative a commission of 5% of the aggregate exercise price of such 
Warrants. However, no compensation will be paid to the Representative in 
connection with the exercise of the Warrants if (a) the market price of the 
Common Stock is lower than the exercise price, (b) the Warrants are held in a 
discretionary account, or (c) the Warrants are exercised in an unsolicited 
transaction where the holder of the Warrant has not stated in writing that 
the transaction was solicited and has not designated in writing the 
Representative as soliciting agent. Unless granted an exemption by the 
Commission from Rule 101 under the Securities Act, the Representative and any 
soliciting broker-dealers will be prohibited from engaging in any 
market-making activities or solicited brokerage activities with regard to the 
Company's securities for the periods prescribed by Rule 101 before the 
solicitation activity or the termination (by waiver or otherwise) of any 
right that the Representative and any soliciting broker-dealers may have to 
receive a fee for the exercise of the Warrants following such solicitation. 
As a result, the Representative and any soliciting broker-dealers may be 
unable to continue to provide a market for the Convertible Preferred Stock, 
Common Stock or Warrants during certain periods while the Warrants are 
exercisable. If the Representative has engaged in any of the activities 
prohibited by Rule 101 during the periods described above, the Representative 
has undertaken to waive unconditionally its rights to receive a commission on 
the exercise of such Warrants. 

   In connection with this Offering, certain Underwriters and selling group 
members and their respective affiliates may engage in transactions that 
stabilize, maintain or otherwise affect the market price of the Securities. 
Such transactions may include stabilization transactions effected in 
accordance with Rule 104 of Regulation M, pursuant to which such persons may 
bid for or purchase Common Stock or Warrants for the purpose of sta- 

                                      65 
    
<PAGE>

   
bilizing their respective market prices. The Underwriters also may create a 
short position for the account of the Underwriters by selling more Securities 
in connection with the Offering than they are committed to purchase from the 
Company, and in such case may purchase Securities in the open market 
following completion of the Offering to cover all or a portion of such short 
position. The Underwriters may also cover all or a portion of such short 
position by exercising the Over-allotment Option referred to above. In 
addition, the Representative, on behalf of the Underwriters, may impose 
"penalty bids" under contractual arrangements with the Underwriters whereby 
it may reclaim from an Underwriter (or dealer participating in the Offering) 
for the account of other Underwriters, the selling concession with respect to 
Securities that are distributed in the Offering but subsequently purchased 
for the account of the Underwriters in the open market. Any of the 
transactions described in this paragraph may result in the maintenance of the 
price of the Securities at a level above that which might otherwise prevail 
in the open market. None of the transactions described in this paragraph is 
required, and, if they are undertaken, they may be discontinued at any time. 
    

   The foregoing is a summary of the principal terms of the agreements 
described above. Reference is made to a copy of each such agreement which are 
filed as exhibits to the Registration Statement of which this Prospectus is a 
part for a more complete description thereof. See "Additional Information." 

   In July 1996, the Representative acted as the managing underwriter in 
connection with the initial public offering by Applied, the Company's sole 
stockholder, pursuant to which Applied sold to the public 5,000,000 shares of 
common stock and 5,000,000 redeemable common stock purchase warrants, at a 
price of $6.00 per share and $.10 per warrant. In addition, the 
Representative exercised an over-allotment option granted to it by Applied to 
purchase an additional 750,000 shares and 750,000 warrants. 

   
                                LEGAL MATTERS

                         INDEPENDENT AUDITORS' REPORT 

To the Board of Directors of 
Commodore Separation Technologies, Inc. 

   We have audited the accompanying balance sheet of Commodore Separation 
Technologies, Inc. (a development stage company) as of June 30, 1996, and the 
related statements of operations, stockholders' deficit, and cash flows for 
the period from November 15, 1995 (date of inception) to June 30, 1996. These 
financial statements are the responsibility of the Company's management. Our 
responsibility is to express an opinion on these financial statements based 
on our audit. 

   We conducted our audit in accordance with generally accepted auditing 
standards. Those standards require that we 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. We believe that our audit provides a 
reasonable basis for our opinion. 

   In our opinion, the financial statements referred to above present fairly, 
in all material respects, the financial position of Commodore Separation 
Technologies, Inc. (a development stage company) as of June 30, 1996, and the 
results of its operations and its cash flows for the period from November 15, 
1995 (date of inception) to June 30, 1996, in conformity with generally 
accepted accounting principles. 

   
   The accompanying financial statements have been prepared assuming that the 
Company will continue as a going concern. As discussed in note 4, the 
Company's significant operating losses and deficits in working capital and 
stockholders' equity raise substantial doubt about its ability to continue as 
a going concern. Management's plans in regard to these matters are also 
described in note 4. The accompanying financial statements do not include any 
adjustment that might result from the outcome of this uncertainty.

                        Notes to Financial Statements 

                                JUNE 30, 1996 

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Organization and Development Stage Company 

   Commodore Separation Technologies, Inc. (a development stage company) (the 
"Company") was incorporated on November 15, 1995, under the laws of the state 
of Delaware. As part of the capitalization of the Company, Commodore 
Environmental Services, Inc. ("Commodore") contributed to the Company 
Commodore's rights to the separation technology and assigned to the Company a 
royalty payable to Srinivas Kilambi, Ph.D., an officer of the Company, equal 
to 2% of future technology revenue that the Company may realize, except for 
applications related to the radionuclides technetium and rhenium, for which 
Dr. Kilambi is entitled to receive a royalty of .66% of net sales (less 
allowances for returns, discounts, commissions, freight and excise or other 
taxes). See Note 5. 

   
   Effective December 2, 1996, Commodore transferred 100% of the capital 
stock of the Company and Company notes aggregating $976,200 to its 69.3% 
subsidiary, Commodore Applied Technologies, Inc. ("Applied"), together with 
the stock of another Commodore subsidiary. Applied paid Commodore $3,000,000 
and, subject to any applicable stockholder approval and notification 
requirements, shall issue Commodore a warrant to purchase 7,500,000 shares of 
Applied common stock for such stock and note. Applied capitalized the 
$976,200 of Company notes. 
    

   The Company is a process technology company which has developed and 
intends to commercialize its separation technology and recovery system, known 
as CST. The Company believes that CST is capable of effectively separating 
and extracting various solubilized materials, including metals, organic 
chemicals, biochemicals, radionuclides and other targeted substances, from 
liquid and gaseous process streams. The Company has not commenced planned 
principal operations. As such, the Company is considered a development stage 
company as defined in SFAS No.7. 

FAIR VALUE OF FINANCIAL INSTRUMENTS 

   The fair value of financial instruments is determined by reference to 
various market data and other valuation techniques as appropriate. Financial 
instruments subject to possible material market variations from the recorded 
book value are a note payable to a stockholder and a note due to a related 
party. There are no material differences in instruments from the recorded 
book value as of June 30, 1996. 

USE OF ACCOUNTING ESTIMATES 

   The preparation 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 
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. 

LOSS PER SHARE 

   
   Loss per share is computed based on the average number of shares 
outstanding of 10,000,000 shares for the period November 15, 1995 (date of 
inception) to June 30, 1996, for the period November 15, 1995 to December 31, 
1995 (unaudited), the six months ended December 31, 1996 (unaudited) and 
cumulative amounts since November 15, 1995 through December 31, 1996 
(unaudited). 
    

CASH EQUIVALENTS 

   For purposes of the statement of cash flows, the Company considers all 
highly liquid debt instruments purchased with an original maturity of three 
months or less to be cash equivalents. 

PROPERTY AND EQUIPMENT 

   Property and equipment are stated at cost. Major additions and 
improvements are capitalized while minor replacements, maintenance and 
repairs which do not increase the useful lives of the assets are expensed as

incurred. Depreciation and amortization have been provided using a 
straight-line method over estimated useful lives of the assets, which vary 
from three to seven years. Research equipment has been constructed by the 
Company and management anticipates it will be placed in service in 1996. In 
connection with the construction, the Company has not capitalized interest as 
part of the asset cost as it is not material. 

   
INTANGIBLE ASSETS 

   The Company has incurred costs associated with applying for certain 
patents. These costs are amortized over 17 years. Accumulated amortization 
was $101 and $1,300 at June 30, 1996 and December 31, 1996 (unaudited), 
respectively. 

RESEARCH AND DEVELOPMENT EXPENDITURES 
    

   Research and development expenditures are charged to operations as 
incurred except for those costs relating to the design or construction of an 
asset having an economic useful life which are then capitalized and 
depreciated over the estimated life. 

   
INCOME TAXES 
    

   Deferred income taxes are provided, when material, in amounts sufficient 
to give effect to timing differences between financial and tax reporting. 

   
DEFERRED OFFERING COSTS 
    

   The Company is currently in the process of drafting and preparing a 
Securities and Exchange Commission registration statement for a public 
offering. Costs related to the public offering including legal, accounting, 
printing, travel and other related costs are capitalized. Upon completion of 
the offering these costs will be netted against the offering proceeds. Should 
the offering be aborted or terminated those costs will be charged to 
operations. 

UNAUDITED FINANCIAL INFORMATION 

   
   The unaudited financial statements include the accounts of the Company and 
include all adjustments (consisting of normal recurring items) which are, in 
the opinion of management, necessary to present fairly the financial position 
as of December 31, 1996 and the results of operations and cash flows for the 
period from November 15, 1995 (date of inception) to December 31, 1995, for 
the six months ended December 31, 1996 and the period from November 15, 1995 
to December 31, 1996. The results of operations for the six months ended 
December 31, 1996 are not necessarily indicative of the results to be 
expected for the entire year. 
    

(2) RELATED PARTY TRANSACTIONS 

   
   The Company owes unsecured advances of $52,600 as of June 30, 1996 to its 
then sole stockholder, Commodore, and $273,600 to its current sole 
stockholder, Applied, as of December 31, 1996. The Company owes interest on 
the advances at the rate of 8 percent per annum. Accrued interest payable at 
June 30, 1996 and December 31, 1996 is $1,035 and $0, respectively. 

   Effective December 2, 1996, Commodore transferred 100% of the capital 
stock of the Company and Company notes aggregating $976,200 to its 69.3% 
subsidiary, Applied, together with the stock of another Commodore subsidiary. 
Applied paid Commodore $3,000,000 and, subject to any applicable stockholder 
approval and notification requirements, shall issue Commodore a warrant to 
purchase 7,500,000 shares of Applied common stock for such stock and note. 
Applied capitalized the $976,200 of Company notes.

</TABLE>

   At June 30, 1996 and December 31, 1996, the Company had tax loss 
carryforwards of approximately $61,000 and $914,000, respectively. The amount 
of and ultimate realization of benefit from the net operating loss for income 
tax purposes is dependent, in part, upon the tax laws in effect, future 
earnings of the Company, and other future events, the effects of which cannot 
be determined. A change in ownership of the Company may reduce the amount of 
loss allowable. These net operating carryforwards begin to expire in 2011. 
    

   A valuation allowance has been established to reduce any potential tax 
benefit as it is not known when or if the Company will realize the benefit of 
net operating losses. 

(4) GOING CONCERN 

   The Company has sustained significant operating losses. In addition, the 
Company has significant deficits in working capital and stockholders' equity. 
These factors create an uncertainty about the Company's ability to continue 
as a going concern. The Company has received advances in working capital from 
its parent company to fund operations to date. There can be no assurance that 
it will continue to receive such assistance. 

   
   The Company commenced drafting and preparing a Securities and Exchange 
Commission registration statement for a public offering of (i) 1,500,000 
Preferred Units, each unit consisting of one share of 10% Senior Convertible 
Redeemable Preferred Stock and one Redeemable Common Stock Purchase Warrant, 
and (ii) 1,500,000 Common Units, each unit consisting of one share of Common 
Stock and one Redeemable Common Stock Purchase Warrant. If the proposed 
public offering is consummated, it will provide funds for continuing 
operations. There is no assurance that the Company will be successful in 
raising the needed working capital and equity through the proposed public 
offering. The ability of the Company to continue as a going concern is 
dependent on the Company obtaining external funding and attaining future 
profitable operations. The financial statements do not include any adjustment 
that might be necessary if the Company is unable to continue as a going 
concern.

(5) ROYALTY AGREEMENTS 

   The Company has an agreement with an officer of the Company whereby the 
officer is to receive a royalty of 2% of collected revenues from the 
Company's membrane separation technology through December 3, 2002, except for 
applications related to the radionuclides technetium and rhenium, for which 
the officer is entitled to receive a royalty of .66% of net sales (less 
allowances for returns, discounts, commissions, freight and excise or other 
taxes). 

   The Company also has a license agreement with Lockheed Martin Energy 
Research Corporation, manager of the Oak Ridge National Laboratory, a U.S. 
Department of Energy national laboratory, whereby Lockheed Martin is to 
receive a royalty of 2% of net sales of the Company's products or processes 
covered under the agreement (less allowances for returns, discounts, 
commissions, freight, and excise or other taxes) up to total net sales of 
$4,000,000 and 1% of net sales thereafter. In addition, the Company has 
agreed to guarantee Lockheed Martin, commencing in the third year of the 
agreement, an annual minimum royalty of $15,000. 

(6) RECENT ACCOUNTING PRONOUNCEMENTS 

   The Financial Accounting Standards Board has issued Statements of 
Financial Accounting Standard Statement No. 121, "Accounting for Long Lived 
Assets" and No. 123, "Accounting and Disclosure of Stock-Based Compensation." 
Statement No. 121 is effective for years beginning after December 15, 1995. 
The effect of adoption of Statement No. 121 will not have a material effect 
on the Company's financial statements. Statement No. 123 is effective for 
awards granted after December 31, 1994, and has required financial 
presentation for years beginning after December 15, 1995. The effect of 
adoption of Statement 123 is not expected to have a material effect on the 
Company's financial statements. 

(7) SUBSEQUENT EVENTS 

Public Stock Offering 

   Subsequent to June 30, 1996, the Company commenced drafting and preparing

of 10% Senior Convertible Redeemable Preferred Stock and one Redeemable 
Common Stock Purchase Warrant, and (ii) 1,500,000 Common Units, each unit

   On September 5, 1996, Commodore (as sole stockholder of the Company)

Company's Board of Directors (the "Plan"), pursuant to which officers, 
directors, and/or key employees and/or consultants of the Company can receive 
incentive stock options and non-qualified stock options to purchase up to an 
aggregate of 1,350,000 shares of the Company's Common Stock (of which no more

(7) Subsequent Events  - (Continued) 

September 5, 1996, December 18, 1996, and January 27, 1997, the Company's 
Board of Directors awarded, effective upon completion of this Offering, 
non-qualified stock options under the Plan to certain key executive officers 
entitling them to purchase an aggregate of 630,000 shares of Common Stock, 
all of which provide for an exercise price equal to the initial public 
offering price of the Common Stock, are exercisable at the rate of 20% of the 
number of options granted in each of calendar 1996 (1997 in the case of one 
executive officer) through 2000, inclusive, beginning on the closing date of 
this Offering and, unless exercised, expire on December 31, 2001 (subject to 
prior termination in accordance with the applicable stock option agreements). 
In addition, non-qualified options to purchase an aggregate of 136,689 shares 
of Common Stock were awarded, effective upon completion of this Offering, to 
members of the Board of Directors who are not employed or otherwise 
affiliated with the Company, all of which are exercisable at an exercise 
price equal to the initial public offering price of the Common Stock, are 
exercisable at the rate of 33 1/3 % of the number of options granted in each 
of calendar 1996 through 1998, inclusive, beginning on the closing date of 
this Offering, and, unless exercised, expire on December 31, 2001 (subject to 
prior termination in accordance with the applicable stock option agreements). 
The exercise price applicable to all outstanding stock options represents not 
less than 100% of the fair market value of the underlying Common Stock as of 
the date that such options were granted, as determined by the Board of 
Directors of the Company on the date that such options were granted. In 
December 1996 and January 1997, Applied, as purchaser of 100% of the capital 
stock of the Company, ratified the Plan and all issuances thereunder. 

   As of January 27, 1997, the Company had granted options for 766,689 
shares, of which none had been exercised. 

BASIS OF PRESENTATION 

   On September 5, 1996, the Company amended its Certificate of Incorporation 
which changed the preferred and common stock to the following: 

   Preferred Stock 

   The Company is authorized to issue up to 5,000,000 shares of preferred 
stock, $.001 par value. 

   Common Stock 

   The Company is authorized to issue up to 50,000,000 shares of common 
stock, $.001 par value. 

   The Company also effected a forward stock split of 150,000 shares for one 
share. This increased the total number of shares of Common Stock issued and 
outstanding to 15,000,000 shares, which were all held by Commodore. On 
November 26, 1996, the outstanding shares were reduced to 10,000,000 based on 
a 1-for-1.50 reverse stock split. 

   The financial statements have been prepared as though the above changes in 
stockholders' equity had occurred at November 15, 1995. 

CAPITAL CONTRIBUTION 

   
   As of December 31, 1996, the Company had received $976,200 of advances 
from Commodore, which have been reflected in the financial statements as a 
contribution to equity. See Note 1. 
    

OWNERSHIP CHANGE 

   Effective December 2, 1996, Commodore sold the shares of the Company to 
its 69.3%-owned subsidiary, Applied. See Note 1.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS. 

   The Certificate of Incorporation and By-laws of the registrant provide 
that the Company shall indemnify officers and directors to the fullest extent 
allowed by the Delaware General Corporation Law, as it now exists and as may 
be amended. 

   The Underwriting Agreement between the Company and National Securities 
Corporation, as representative of the several Underwriters (the 
"Representative"), provides for indemnification of the officers and directors 
of the registrant under certain circumstances. 

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES. 

   (a) In November 1995, the registrant issued 100 shares of its Common Stock 
to its then corporate parent, Commodore Environmental Services, Inc. 
("Commodore"). On September 5, 1996, the Company effected a 150,000-for-one 
stock split, and issued a new stock certificate to Commodore representing 
15,000,000 shares of the registrant's Common Stock. On November 26, 1996, the 
registrant effected a one-for-1.50 reverse stock split, and issued a new 
stock certificate to Commodore representing 10,000,000 shares of the 
registrant's Common Stock. Effective December 2, 1996 Commodore transferred 
100% of the registrant's Common Stock to Commodore Applied Technologies, 
Inc., a 69.3%-owned subsidiary of Commodore. 

   In September and December 1996, and January 1997, the registrant issued to 
officers and directors, effective upon completion of this Offering, pursuant 
to the registrant's 1996 Stock Option Plan, options to purchase an aggregate 
of 766,689 shares of the registrant's Common Stock. 

   (b) There were no underwriters, brokers or finders employed in connection 
with any of the transactions set forth in Item 15(a). 

   (c) The issuances described in Item 15(a) were deemed exempt from 
registration under the Securities Act in reliance on Section 4(2) of the 
Securities Act as transactions by an issuer not involving any public 
offering. In addition, certain of the issuances described in Item 15(a) were 
deemed exempt from registration under the Securities Act in reliance upon 
Rule 701 promulgated under the Securities Act. The recipients of securities 
in each such transaction represented their intentions to acquire the 
securities for investment only and not with a view to or for sale in 
connection with any distribution thereof and appropriate legends were affixed 
to the share certificates issued in such transactions. All recipients had 
adequate access, through their relationships with the registrant, to 
information about the registrant. 

   The registrant has not otherwise issued any securities exempt from the 
registration requirements of the Securities Act pursuant to Section 4(2) 
thereof.

ITEM 17. UNDERTAKINGS. 

   The undersigned registrant hereby undertakes as follows: 

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

       (i)  To include any prospectus required by Section 10(a)(3) of the 
            Securities 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 this 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 
             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) under the Securities 
             Act 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 in such information in the 
             Registration Statement. 

   (b) 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. 

   (c) 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 provisions described in Item 14, 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 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 such issue. 

   (d) For purposes of determining any liability under the Securities Act, 
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 shall be deemed to be part of this 
Registration Statement as of the time it was declared effective. 

   (e) For the purpose of determining any liability under the Securities Act, 
each post-effective amendment that contains a form of prospectus 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. 

   (f) 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. 

                                      II-3

                                      - 2 -

<PAGE>




                  (i) The Company has prepared and filed with the Securities and
         Exchange Commission (the "Commission") a registration statement, and an
         amendment or amendments thereto, on Form S-1 (No. 333-11813), including
         any related preliminary prospectus ("Preliminary Prospectus"), for the
         registration of the Firm Securities, the Option Securities, the
         Representative's Warrants and the Representative's Securities under the
         Securities Act of 1933, as amended (the "Act"), which registration
         statement and amendment or amendments have been prepared by the Company
         in conformity with the requirements of the Act, and the rules and
         regulations (the "Regulations") of the Commission under the Act. The
         Company will promptly file a further amendment to said registration
         statement in the form heretofore delivered to the Underwriters and will
         not file any other amendment thereto to which the Underwriters shall
         have objected in writing after having been furnished with a copy
         thereof. Except as the context may otherwise require, such registration
         statement, as amended, on file with the Commission at the time the
         registration statement becomes effective (including the prospectus,
         financial statements, schedules, exhibits and all other documents filed
         as a part thereof or incorporated therein (including, but not limited
         to those documents or information incorporated by reference therein)
         and all information deemed to be a part thereof as of such time
         pursuant to paragraph (b) of Rule 430(A) of the Regulations), is
         hereinafter called the "Registration Statement", and the form of
         prospectus in the form first filed with the Commission pursuant to Rule
         424(b) of the Regulations, is hereinafter called the "Prospectus." For
         purposes hereof, "Rules and Regulations" mean the rules and regulations
         adopted by the Commission under either the Act or the Securities
         Exchange Act of 1934, as amended (the "Exchange Act"), as applicable.

                  (ii) Neither the Commission nor any state regulatory authority
         has issued any order preventing or suspending the use of any
         Preliminary Prospectus, the Registration Statement or Prospectus or any
         part of any thereof and no proceedings for a stop order suspending the
         effectiveness of the Registration Statement or any of the Company's
         securities have been instituted or are pending or threatened. Each of
         the Preliminary Prospectus, the Registration Statement and Prospectus
         at the time of filing thereof conformed with the requirements of the
         Act and the Rules and Regulations, and none of the Preliminary
         Prospectus, the Registration Statement or Prospectus at the time of
         filing thereof contained an untrue statement of a material fact or
         omitted to state a material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading, except that this
         representation and warranty does not apply to statements made in
         reliance upon and in conformity with written information furnished to
         the Company with respect to the Underwriters by or on behalf of the
         Underwriters expressly for use in such Preliminary Prospectus,
         Registration Statement or Prospectus or any amendment thereof or
         supplement thereto.

                  (iii) When the Registration Statement becomes effective and at
         all times subsequent thereto up to the Closing Date (as defined herein)
         and each Option Closing Date (as defined herein), if any, and during
         such longer period as the Prospectus may


 
                                      - 3 -

<PAGE>



         be required to be delivered in connection with sales by the
         Underwriters or a dealer, the Registration Statement and the Prospectus
         will contain all statements which are required to be stated therein in
         accordance with the Act and the Rules and Regulations, and will conform
         to the requirements of the Act and the Rules and Regulations; neither
         the Registration Statement nor the Prospectus, nor any amendment or
         supplement thereto, will contain any untrue statement of a material
         fact or omit to state any material fact required to be stated therein
         or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading, provided,
         however, that this representation and warranty does not apply to
         statements made or statements omitted in reliance upon and in strict
         conformity with information furnished to the Company in writing by or
         on behalf of any Underwriter expressly for use in the Preliminary
         Prospectus, Registration Statement or Prospectus or any amendment
         thereof or supplement thereto.

                  (iv) The Company has been duly organized and is validly
         existing as a corporation in good standing under the laws of the state
         of its incorporation. Except as set forth in the Prospectus, the
         Company does not own an interest in any corporation, partnership,
         trust, joint venture or other business entity. The Company is duly
         qualified and licensed and in good standing as a foreign corporation in
         each jurisdiction in which its ownership or leasing of any properties
         or the character of its operations requires such qualification or
         licensing. The Company has all requisite power and authority (corporate
         and other), and has obtained any and all necessary authorizations,
         approvals, orders, licenses, certificates, franchises and permits of
         and from all governmental or regulatory officials and bodies
         (including, without limitation, those having jurisdiction over
         environmental or similar matters), to own or lease its properties and
         conduct its business as described in the Prospectus; the Company is and
         has been doing business in compliance with all such authorizations,
         approvals, orders, licenses, certificates, franchises and permits and
         all applicable federal, state, local and foreign laws, rules and
         regulations; and the Company has not received any notice of proceedings
         relating to the revocation or modification of any such authorization,
         approval, order, license, certificate, franchise, or permit which,
         singly or in the aggregate, if the subject of an unfavorable decision,
         ruling or finding, would materially and adversely affect the condition,
         financial or otherwise, or the earnings, position, prospects, value,
         operation, properties, business or results of operations of the
         Company. The disclosures in the Registration Statement concerning the
         effects of federal, state, local, and foreign laws, rules and
         regulations on the Company's business as currently conducted and as
         contemplated are correct in all material respects and do not omit to
         state a material fact required to be stated therein or necessary to
         make the statements contained therein not misleading in light of the
         circumstances under which they were made.

                  (v) The Company has a duly authorized, issued and outstanding
         capitalization as set forth in the Prospectus under "Capitalization"
         and "Description of Securities" and will have the adjusted
         capitalization set forth therein on the Closing Date and each Option
         Closing Date, if any, based upon the assumptions set forth therein, and
         the Company is


 
                                      - 4 -

         not a party to or bound by any instrument, agreement or other
         arrangement providing for it to issue any capital stock, rights,
         warrants, options or other securities, except for this Agreement, the
         Warrant Agreement, the Representative's Warrant Agreement and as
         described in the Prospectus. The Securities and all other securities
         issued or issuable by the Company conform or, when issued and paid for,
         will conform, in all respects to all statements with respect thereto
         contained in the Registration Statement and the Prospectus. All issued
         and outstanding securities of the Company have been duly authorized and
         validly issued and are fully paid and non-assessable and the holders
         thereof have no rights of rescission with respect thereto, and are not
         subject to personal liability by reason of being such holders; and none
         of such securities were issued in violation of the preemptive rights of
         any holders of any security of the Company or similar contractual
         rights granted by the Company. The Firm Securities, the Option
         Securities, the Representative's Warrants and the Representative's
         Securities are not and will not be subject to any preemptive or other
         similar rights of any stockholder, have been duly authorized and, when
         issued, paid for and delivered in accordance with the terms hereof,
         will be validly issued, fully paid and non-assessable and will conform
         to the description thereof contained in the Prospectus; the holders
         thereof will not be subject to any liability solely as such holders;
         all corporate action required to be taken for the authorization, issue
         and sale of the Firm Securities, the Option Securities, the
         Representative's Warrants and the Representative's Securities has been
         duly and validly taken; and the certificates representing the Firm
         Securities, the Option Securities, the Representative's Warrants and
         the Representative's Securities will be in due and proper form. Upon
         the issuance and delivery pursuant to the terms hereof of the Firm
         Securities, the Option Securities, the Representative's Warrants and
         the Representative's Securities to be sold by the Company hereunder,
         the Underwriters or the Representative, as the case may be, will
         acquire good and marketable title to such Firm Securities, Option
         Securities, Representative's Warrants and Representative's Securities
         free and clear of any lien, charge, claim, encumbrance, pledge,
         security interest, defect or other restriction or equity of any kind
         whatsoever.

                  (vi) The financial statements of the Company, together with
         the related notes and schedules thereto, included in the Registration
         Statement, each Preliminary Prospectus and the Prospectus fairly
         present the financial position, income, changes in cash flow, changes
         in stockholders' equity and the results of operations of the Company at
         the respective dates and for the respective periods to which they apply
         and such financial statements have been prepared in conformity with
         generally accepted accounting principles and the Rules and Regulations,
         consistently applied throughout the periods involved and such financial
         statements as are audited have been examined by Tanner + Co., who are
         independent certified public accountants within the meaning of the Act
         and the Rules and Regulations, as indicated in their reports filed
         therewith. There has been no adverse change or development involving a
         prospective adverse change in the condition, financial or otherwise, or
         in the earnings, position, prospects, value, operation, properties,
         business, or results of operations of the Company, whether or not
         arising in the ordinary course of business, since the date of the
         financial statements


 
                                      - 5 -

<PAGE>



         included in the Registration Statement and the Prospectus and the
         outstanding debt, the property, both tangible and intangible, and the
         business of the Company conform in all material respects to the
         descriptions thereof contained in the Registration Statement and the
         Prospectus. Financial information (including, without limitation, any
         pro forma financial information) set forth in the Prospectus under the
         headings "Summary Financial Data", "Selected Financial Data,"
         "Capitalization," and "Management's Discussion and Analysis of
         Financial Condition and Results of Operations," fairly present, on the
         basis stated in the Prospectus, the information set forth therein, and
         have been derived from or compiled on a basis consistent with that of
         the audited financial statements included in the Prospectus; and, in
         the case of pro forma financial information, if any, the assumptions
         used in the preparation thereof are reasonable and the adjustments used
         therein are appropriate to give effect to the transactions and
         circumstances referred to therein. The amounts shown as accrued for
         current and deferred income and other taxes in such financial
         statements are sufficient for the payment of all accrued and unpaid
         federal, state, local and foreign income taxes, interest, penalties,
         assessments or deficiencies applicable to the Company, whether disputed
         or not, for the applicable period then ended and periods prior thereto;
         adequate allowance for doubtful accounts has been provided for
         unindemnified losses due to the operations of the Company; and the
         statements of income do not contain any items of special or
         nonrecurring income not earned in the ordinary course of business,
         except as specified in the notes thereto.

                  (vii) The Company (i) has paid all federal, state, local, and
         foreign taxes for which it is liable, including, but not limited to,
         withholding taxes and amounts payable under Chapters 21 through 24 of
         the Internal Revenue Code of 1986, as amended (the "Code"), and has
         furnished all information returns it is required to furnish pursuant to
         the Code, (ii) has established adequate reserves for such taxes which
         are not due and payable, and (iii) does not have any tax deficiency or
         claims outstanding, proposed or assessed against it.

                  (viii) No transfer tax, stamp duty or other similar tax is
         payable by or on behalf of the Underwriters in connection with (i) the
         issuance by the Company of the Firm Securities, the Option Securities,
         the Representative's Warrants or the Representative's Securities, (ii)
         the purchase by the Underwriters of the Firm Securities and the Option
         Securities from the Company and the purchase by the Representative of
         the Representative's Warrants from the Company, (iii) the consummation
         by the Company of any of its obligations under this Agreement, or (iv)
         resales of the Firm Securities and the Option Securities in connection
         with the distribution contemplated hereby.

                  (ix) The Company maintains insurance policies, including, but
         not limited to, general and product liability, environmental and
         property insurance, which insures the Company and its employees against
         such losses and risks generally insured against by comparable
         businesses. The Company (A) has not failed to give notice or present
         any insurance claim with respect to any matter, including but not
         limited to the Company's business, property or employees, under any
         insurance policy or surety bond in a due and


 
                                      - 6 -

<PAGE>



         timely manner, (B) does not have any disputes or claims against any
         underwriter of such insurance policies or surety bonds or has failed to
         pay any premiums due and payable thereunder, or (C) has not failed to
         comply with all conditions contained in such insurance policies and
         surety bonds. There are no facts or circumstances under any such
         insurance policy or surety bond which would relieve any insurer of its
         obligation to satisfy in full any valid claim of the Company.

                  (x) There is no action, suit, proceeding, inquiry,
         arbitration, investigation, litigation or governmental proceeding
         (including, without limitation, those having jurisdiction over
         environmental or similar matters), domestic or foreign, pending or
         threatened against (or circumstances that may give rise to the same),
         or involving the properties or business of, the Company which (i)
         questions the validity of the capital stock of the Company, this
         Agreement, the Warrant Agreement or the Representative's Warrant
         Agreement, or of any action taken or to be taken by the Company
         pursuant to or in connection with this Agreement, the Warrant Agreement
         or the Representative's Warrant Agreement, (ii) is required to be
         disclosed in the Registration Statement which is not so disclosed (and
         such proceedings as are summarized in the Registration Statement are
         accurately summarized in all material respects), or (iii) might
         materially and adversely affect the condition, financial or otherwise,
         or the earnings, position, prospects, stockholders' equity, value,
         operation, properties, business or results of operations of the
         Company.

                  (xi) The Company has full legal right, power and authority to
         authorize, issue, deliver and sell the Firm Securities, the Option
         Securities, the Representative's Warrants and the Representative's
         Securities, enter into this Agreement, the Warrant Agreement and the
         Representative's Warrant Agreement and to consummate the transactions
         provided for in this Agreement, the Warrant Agreement and the
         Representative's Warrant Agreement; and this Agreement, the Warrant
         Agreement and the Representative's Warrant Agreement have each been
         duly and properly authorized, executed and delivered by the Company.
         Each of this Agreement, the Warrant Agreement and the Representative's
         Warrant Agreement constitutes a legal, valid and binding agreement of
         the Company enforceable against the Company in accordance with its
         terms, and none of the Company's issue and sale of the Firm Securities,
         the Option Securities, the Representative's Warrants and the
         Representative's Securities, execution or delivery of this Agreement,
         the Warrant Agreement or the Representative's Warrant Agreement, its
         performance hereunder and thereunder, its consummation of the
         transactions contemplated herein and therein, or the conduct of its
         business as described in the Registration Statement, the Prospectus,
         and any amendments or supplements thereto, conflicts with or will
         conflict with or results or will result in any breach or violation of
         any of the terms or provisions of, or constitutes or will constitute a
         default under, or result in the creation or imposition of any lien,
         charge, claim, encumbrance, pledge, security interest, defect or other
         restriction or equity of any kind whatsoever upon, any property or
         assets (tangible or intangible) of the Company pursuant to the terms of
         (i) the certificate of incorporation or by-laws of the Company, (ii)
         any license, contract,


 
                                      - 7 -

<PAGE>



         collective bargaining agreement, indenture, mortgage, deed of trust,
         lease, voting trust agreement, stockholders agreement, note, loan or
         credit agreement or any other agreement or instrument to which the
         Company is a party or by which the Company is or may be bound or to
         which either of its properties or assets (tangible or intangible) is or
         may be subject, or any indebtedness, or (iii) any statute, judgment,
         decree, order, rule or regulation applicable to the Company of any
         arbitrator, court, regulatory body or administrative agency or other
         governmental agency or body (including, without limitation, those
         having jurisdiction over environmental or similar matters), domestic or
         foreign, having jurisdiction over the Company or any of its activities
         or properties, which in any event could have a material adverse effect
         on the condition (financial or otherwise), business, properties,
         financial position or results of operations of the Company.

                  (xii) No consent, approval, authorization or order of, and no
         filing with, any court, regulatory body, government agency or other
         body, domestic or foreign, is required for the issuance of the Firm
         Securities, the Option Securities, the Representative's Warrants and
         the Representative's Securities pursuant to the Prospectus and the
         Registration Statement, the performance of this Agreement, the Warrant
         Agreement and the Representative's Warrant Agreement and the
         transactions contemplated hereby and thereby, including without
         limitation, any waiver of any preemptive, first refusal or other rights
         that any entity or person may have for the issue and/or sale of any of
         the Firm Securities, the Option Securities, the Representative's
         Warrants and the Representative's Securities, except such as have been
         or may be obtained under the Act or may be required under state
         securities or Blue Sky laws in connection with the Underwriters'
         purchase and distribution of the Firm Securities and the Option
         Securities, and the Representative's Warrants to be sold by the Company
         hereunder.

                  (xiii) All executed agreements, contracts or other documents
         or copies of executed agreements, contracts or other documents filed as
         exhibits to the Registration Statement to which the Company is a party
         or by which it may be bound or to which its assets, properties or
         business may be subject have been duly and validly authorized, executed
         and delivered by the Company and constitute the legal, valid and
         binding agreements of the Company enforceable against the Company in
         accordance with their respective terms. The descriptions in the
         Registration Statement of agreements, contracts and other documents are
         accurate and fairly present the information required to be shown with
         respect thereto by Form S-1, and there are no contracts or other
         documents which are required by the Act to be described in the
         Registration Statement or filed as exhibits to the Registration
         Statement which are not described or filed as required, and the
         exhibits which have been filed are complete and correct copies of the
         documents of which they purport to be copies.

                  
                  (xiv) Subsequent to the respective dates as of which
         information is set forth in the Registration Statement and Prospectus,
         and except as may otherwise be indicated or


 
                                      - 8 -

<PAGE>



         contemplated herein or therein, the Company has not (i) issued any
         securities or incurred any liability or obligation, direct or
         contingent, for borrowed money, (ii) entered into any transaction other
         than in the ordinary course of business, or (iii) declared or paid any
         dividend or made any other distribution on or in respect of its capital
         stock of any class, and there has not been any change in the capital
         stock, or any change in the debt (long or short term) or liabilities or
         material adverse change in or affecting the general affairs,
         management, financial operations, stockholders' equity or results of
         operations of the Company.

                  (xv) No default exists in the due performance and observance
         of any term, covenant or condition of any license, contract, collective
         bargaining agreement, indenture, mortgage, installment sale agreement,
         lease, deed of trust, voting trust agreement, stockholders agreement,
         partnership agreement, note, loan or credit agreement, purchase order,
         or any other agreement or instrument evidencing an obligation for
         borrowed money, or any other material agreement or instrument to which
         the Company is a party or by which the Company may be bound or to which
         the property or assets (tangible or intangible) of the Company is
         subject or affected.

                  (xvi) The Company has generally enjoyed a satisfactory
         employer-employee relationship with its employees and is in compliance
         in all material respects with all federal, state, local, and foreign
         laws and regulations respecting employment and employment practices,
         terms and conditions of employment and wages and hours. There are no
         pending investigations involving the Company by the U.S. Department of
         Labor, or any other governmental agency responsible for the enforcement
         of such federal, state, local, or foreign laws and regulations. There
         is no unfair labor practice charge or complaint against the Company
         pending before the National Labor Relations Board or any lockout,
         strike, picketing, boycott, dispute, slowdown or stoppage pending or
         threatened against or involving the Company, or any predecessor entity,
         and none has ever occurred. No representation question exists
         respecting the employees of the Company, and no collective bargaining
         agreement or modification thereof is currently being negotiated by the
         Company. No grievance or arbitration proceeding is pending under any
         expired or existing collective bargaining agreements of the Company. No
         labor dispute with the employees of the Company exists, or, to its
         knowledge, is imminent.

                  (xvii) The Company does not maintain, sponsor or contribute to
         any program or arrangement that is an "employee pension benefit plan,"
         an "employee welfare benefit plan," or a "multiemployer plan" as such
         terms are defined in Sections 3(2), 3(1) and 3(37), respectively, of
         the Employee Retirement Income Security Act of 1974, as amended
         ("ERISA") ("ERISA Plans"). The Company does not maintain or contribute,
         now or at any time previously, to a defined benefit plan, as defined in
         Section 3(35) of ERISA. No ERISA Plan (or any trust created thereunder)
         has engaged in a "prohibited transaction" within the meaning of Section
         406 of ERISA or Section 4975 of the Code, which could subject the
         Company to any tax penalty on prohibited transactions and which


 
                                      - 9 -

<PAGE>



         has not adequately been corrected. Each ERISA Plan is in compliance
         with all reporting, disclosure and other requirements of the Code and
         ERISA as they relate to any such ERISA Plan. Determination letters have
         been received from the Internal Revenue Service with respect to each
         ERISA Plan which is intended to comply with Code Section 401(a),
         stating that such ERISA Plan and the attendant trust are qualified
         thereunder. The Company has never completely or partially withdrawn
         from a "multiemployer plan."

                  (xviii) Neither the Company nor any of its employees,
         directors, stockholders, partners, or affiliates (within the meaning of
         the Rules and Regulations) of any of the foregoing has taken or will
         take, directly or indirectly, any action designed to or which has
         constituted or which might be expected to cause or result in, under the
         Exchange Act, or otherwise, stabilization or manipulation of the price
         of any security of the Company to facilitate the sale or resale of the
         Securities or otherwise.

                  (xix) Except as otherwise disclosed in the Prospectus, none of
         the patents, patent applications, trademarks, service marks, trade
         names and copyrights, and licenses and rights to the foregoing
         presently owned or held by the Company are in dispute so far as known
         by the Company or are in any conflict with the right of any other
         person or entity. The Company (i) owns or has the right to use, free
         and clear of all liens, charges, claims, encumbrances, pledges,
         security interests, defects or other restrictions or equities of any
         kind whatsoever, all patents, trademarks, service marks, trade names
         and copyrights, technology and licenses and rights with respect to the
         foregoing, used in the conduct of its business as now conducted or
         proposed to be conducted without infringing upon or otherwise acting
         adversely to the right or claimed right of any person, corporation or
         other entity under or with respect to any of the foregoing and (ii)
         except as disclosed in the Prospectus, is not obligated or under any
         liability whatsoever to make any payment by way of royalties, fees or
         otherwise to any owner or licensee of, or other claimant to, any
         patent, trademark, service mark, trade name, copyright, know-how,
         technology or other intangible asset, with respect to the use thereof
         or in connection with the conduct of its business or otherwise, except
         where failure to obtain any such patents, trademarks, service marks,
         trade names, copyrights, know how, technology or other intangible
         assets would not have a material adverse effect on the financial
         condition, business or results of operations of the Company.

                  (xx) The Company owns and has the unrestricted right to use
         all trade secrets, know-how (including all other unpatented and/or
         unpatentable proprietary or confidential information, systems or
         procedures), inventions, designs, processes, works of authorship,
         computer programs and technical data and information (collectively
         herein "intellectual property") that are material to the development,
         manufacture, operation and sale of all products and services sold or
         proposed to be sold by the Company, free and clear of and without
         violating any right, lien, or claim of others, including without
         limitation, former employers of its employees; provided, however, that
         the possibility exists that other persons or entities, completely
         independently of the Company, or its employees or agents, could have
         developed trade secrets or items of technical information similar or

         whatsoever, other than those referred to in the Prospectus and liens
         for taxes not yet due and payable.

                  (xxiv) The Company has caused to be duly executed legally
         binding and enforceable agreements pursuant to which each of the
         Company's officers, directors, stockholders and holders of securities

         Underwriters' compensation, as determined by the National Association
         of Securities Dealers, Inc. ("NASD").

                  (xxvi) The Convertible Preferred Stock, Common Stock and
         Redeemable Warrants have been approved for quotation on the Nasdaq
         SmallCap Market ("Nasdaq"), subject to official notice of issuance.

                  (xxvii) Neither the Company nor any of its officers,
         employees, agents or any other person acting on behalf of the Company
         has, directly or indirectly, given or agreed to give any money, gift or
         similar benefit (other than legal price concessions to customers in the
         ordinary course of business) to any customer, supplier, employee or
         agent of a customer or supplier, or official or employee of any
         governmental agency (domestic or foreign) or instrumentality of any
         government (domestic or foreign) or any political party or candidate
         for office (domestic or foreign) or other person who was, is, or may be
         in a position to help or hinder the business of the Company (or assist
         the Company in connection with any actual or proposed transaction)
         which (a) might subject the Company, or any other such person to any
         damage or penalty in any civil, criminal or governmental litigation or
         proceeding (domestic or foreign), (b) if not given in the past, might
         have had a material adverse effect on the assets, business or
         operations of the Company, or (c) if not continued in the future, might
         adversely affect the assets, business, condition, financial or
         otherwise, earnings, position, properties, value, operations or
         prospects of the Company. The Company's internal accounting controls
         are sufficient to cause the Company to comply with the Foreign Corrupt
         Practices Act of 1977, as amended.

                  (xxviii) Except as set forth in the Prospectus, no officer,
         director, stockholder or partner of the Company, or any "affiliate" or
         "associate" (as these terms are defined in Rule 405 promulgated under
         the Rules and Regulations) of any of the foregoing persons or entities
         has or has had, either directly or indirectly, (i) an interest in any
         person or entity which (A) furnishes or sells services or products
         which are furnished or sold or are proposed to be furnished or sold by
         the Company, or (B) purchases from or sells or furnishes to the Company
         any goods or services, or (ii) a beneficiary interest in any contract
         or agreement to which the Company is a party or by which it may be

         Relationships and Related Transactions," there are no existing
         agreements, arrangements, understandings or transactions, or proposed
         agreements, arrangements, understandings or transactions, between or
         among the Company, and any officer, director, or 5% or greater
         securityholder of the Company, or any partner, affiliate or associate
         of any of the foregoing persons or entities.

                  (xxix) Any certificate signed by any officer of the Company,
         and delivered to the Underwriters or to Underwriters' Counsel (as
         defined herein) shall be deemed a representation and warranty by the
         Company to the Underwriters as to the matters covered thereby.

                  (xxx) The minute books of the Company have been made available
         to the Underwriters and contain a complete summary of all meetings and
         actions of the directors (including committees thereof) and
         stockholders of the Company, since the time of its incorporation, and
         reflect all transactions referred to in such minutes accurately in all
         material respects.

                  (xxxi) Except and to the extent described in the Prospectus,
         no holders of any securities of the Company or of any options, warrants
         or other convertible or exchangeable securities of the Company have the
         right to include any securities issued by the Company in the
         Registration Statement or any registration statement to be filed by the
         Company or to require the Company to file a registration statement
         under the Act and no person or entity holds any anti-dilution rights
         with respect to any securities of the Company.

                  (xxxii) (A) The Company is in compliance in all material
         respects with all federal, state, local or foreign laws, common law,
         rules, codes, administrative orders or regulations relating to
         pollution or protection of human health, the environment (including,
         without limitation, ambient air, surface water, groundwater, land
         surface or subsurface strata) or wildlife, including without limitation
         all laws, common law, rules, codes, administrative orders and
         regulations relating to the release or threatened release of chemicals,
         pollutants, contaminants, wastes, toxic substances, hazardous
         substances, petroleum or petroleum products (collectively, "Hazardous
         Materials") or to the manufacture, processing, distribution, use,
         treatment, storage, disposal, transport or handling of Hazardous
         Materials (collectively, "Environmental Laws") and (B) to the best of
         the Company's knowledge, there are no events or circumstances that
         could form the basis of an order for clean-up or remediation, or an
         action, suit or proceeding by any private party or governmental body or
         agency, against or affecting the Company relating to any Hazardous
         Materials or the violation of any Environmental Laws, which order or
         action, suit or proceeding could have a material adverse effect on the
         condition (financial or otherwise), business, properties, financial
         position or results of operations of the Company. The Company has no
         reason to believe that it will not receive all necessary and required
         approvals, authorizations, validations and certifications from
         applicable regulatory authorities to enable the Company to commence
         full operations as contemplated in the Registration Statement and the
         Prospectus.

                  (xxxiii) In the ordinary course of its business, the Company
         conducts a periodic review of the effect of Environmental Laws on the
         business, operations and properties of the Company, in the course of
         which it identifies and evaluates associated costs and liabilities
         (including, without limitation, any capital or operating expenditures
         required for clean-up, closure of properties or compliance with
         Environmental Laws or any permit, license or approval, any related
         constraints on operating activities and any potential liabilities to
         third parties). On the basis of such review, the Company has reasonably
         concluded that such associated costs and liabilities would not, singly
         or in the aggregate, have a material adverse effect on the Company.

                  (xxxiv) The Company has as of the effective date of the

         each of Carl O. Magnell, James M. DeAngelis, Srinivas Kilambi, Ph.D.
         and Michael D. Kiehnau in the forms filed as Exhibits 10.2, 10.3, 10.4
         and 10.5, respectively, to the Registration Statement and Commodore
         Environmental Services, Inc., a Delaware corporation and the majority
         stockholder of the Parent (as hereinafter defined) ("Commodore"), has
         entered into an employment agreement with Edwin L. Harper in the form
         filed as Exhibit 10.6 to the Registration Statement and (ii) purchased

         and Kilambi in the amount of $1 million each, which policies name the
         Company as the sole beneficiary thereof.

                  (xxxv) As of the date hereof, the Company does not have more
         than 10,000,000 shares of Common Stock issued and outstanding
         (including securities with equivalent rights as the Common Stock and
         shares of Common Stock, or such equivalent securities, issuable upon
         exercise of any and all options, warrants and other contract rights and
         securities convertible directly or indirectly into shares of Common
         Stock or such equivalent securities, but excluding up to 1,177,250
         shares of Common Stock issuable upon the exercise of options granted
         under the Company's 1996 Stock Option Plan at prices not less than the
         initial public offering price per Common Share).

                  (xxxvi) The Company confirms as of the date hereof that it is
         in compliance with all provisions of Section 1 of Laws of Florida,
         Chapter 92-198, An Act Relating to Disclosure of Doing Business with
         Cuba, and the Company further agrees that if it or any affiliate
         commences engaging in business with the government of Cuba or with any
         person or affiliate located in Cuba after the date the Registration
         Statement becomes or has become effective with the Commission or with
         the Florida Department of Banking and Finance (the "Department"),
         whichever date is later, or if the information reported or incorporated
         by reference in the Prospectus, if any, concerning the Company's, or
         any affiliate's, business with Cuba or with any person or affiliate
         located in Cuba changes in any material way, the Company will provide
         the Department notice of such business or change, as appropriate, in a
         form acceptable to the Department.

                  (xxxvii) The Company has furnished the Representative and
         Underwriters' Counsel with a true and complete copy of the Commodore
         SEC Documents. As used herein, the "Commodore SEC Documents" shall mean
         all documents (other than preliminary material) that Commodore has
         filed or has been required to file with the Commission since January 1,
         1994. As of its filing date (and, with respect to any registration
         statement, the date on which it or any post-effective amendment was
         declared effective) other than with respect to changes that may be
         necessitated by virtue of comments made by the Commission related to
         the Registration Statement that may be applicable to Commodore, each
         Commodore SEC Document was in compliance, in all material respects,
         with the applicable requirements of the Act and the Exchange Act,
         contained no untrue statement of a material fact and did not omit any
         statement of a material fact required to be stated therein or necessary
         to make the statements therein,


 
                                     - 14 -

         in light of the circumstances under which they were made, not
         misleading. The financial statements of Commodore included in the
         Commodore SEC Documents complied, at the time of filing with the
         Commission (and, with respect to any registration statement, at the
         time it was declared effective), as to form, in all material respects,
         with applicable accounting requirements and the published rules and
         regulations of the Commission with respect thereto, were prepared in
         accordance with generally accepted accounting principles applied on a
         consistent basis during the periods involved and fairly present, in all
         material respects, the consolidated financial position of Commodore and
         its consolidated subsidiaries as of the dates thereof and the
         consolidated results of their operations for the periods presented.
         Since January 1, 1996, there has not been any change in the business,
         assets, condition, financial or otherwise, or results of operations of
         Commodore or any of its subsidiaries which might materially and
         adversely affect the condition, financial or otherwise, or the
         earnings, position, prospects, stockholders' equity, value, operation,
         properties, business or results of operations of the Company.

                  (xxxviii) The Company is not, and upon the issuance and sale
         of the Securities as herein contemplated and the application of the net
         proceeds therefrom as described in the Prospectus under the caption
         "Use of Proceeds" will not be, an "investment company" or an entity
         "controlled" by an "investment company" as such terms are defined in
         the Investment Company Act of 1940, as amended (the "1940 Act").

                  (xxxix) The Company maintains a system of internal accounting
         controls sufficient to provide reasonable assurance that (i)
         transactions are executed in accordance with management's general or
         specific authorizations; (ii) transactions are recorded as necessary to
         permit preparations of financial statements in conformity with
         generally accepted accounting principles and to maintain accountability
         for assets; (iii) access to assets is permitted only in accordance with
         management's general or specific authorizations; and (iv) the recorded
         accountability for assets is compared with the existing assets at
         reasonable intervals and appropriate action is taken with respect to
         any differences.

                  (xl) The Company has entered into a warrant agreement
         substantially in the form filed as Exhibit 4.2 to the Registration
         Statement (the "Warrant Agreement") with the Representative and The
         Bank of New York, as Warrant Agent, in form and substance satisfactory
         to the Representative, with respect to the Redeemable Warrants and
         providing for the payment of the commission contemplated by Section
         4(a)(xxii).

                  (xli) None of the directors or officers of the Company have
         ever been an officer of Wico Holding Corp., Wico Corp., Wico Gaming
         Supply Corp. or Conquest Industries.

             (b) Commodore Applied Technologies, Inc., a Delaware corporation
and the sole stockholder of the Company ("Parent"), represents and warrants to,
and agrees with, each of the

Underwriters as of the date hereof, and as of the Closing Date and each Option
Closing Date, if any, as follows:

                  (i) Parent has full legal right, power and authority to enter
         into this Agreement, and to consummate the transactions provided for in
         this Agreement; and this Agreement has been duly and properly
         authorized, executed and delivered by the Parent. This Agreement
         constitutes a legal, valid and binding agreement of Parent enforceable
         against Parent in accordance with its terms, and none of the Parent's
         execution or delivery of this Agreement, its performance hereunder, or
         its consummation of the transactions contemplated herein, conflicts
         with or will conflict with or results or will result in any breach or
         violation of any of the terms or provisions of, or constitutes or will
         constitute a default under, or result in the creation or imposition of
         any lien, charge, claim, encumbrance, pledge, security interest, defect
         or other restriction or equity of any kind whatsoever upon, any
         property or assets (tangible or intangible) of the Parent pursuant to
         the terms of (i) the certificate of incorporation or by-laws of the
         Parent, (ii) any license, contract, collective bargaining agreement,
         indenture, mortgage, deed of trust, lease, voting trust agreement,
         stockholders agreement, note, loan or credit agreement or any other
         agreement or instrument to which the Parent is a party or by which the
         Parent is or may be bound or to which either its properties or assets
         (tangible or intangible) is or may be subject, or any indebtedness, or
         (iii) any statute, judgment, decree, order, rule or regulation
         applicable to the Parent of any arbitrator, court, regulatory body or
         administrative agency or other governmental agency or body (including,
         without limitation, those having jurisdiction over environmental or
         similar matters), domestic or foreign, having jurisdiction over the
         Parent or any of its activities or properties which in any event could
         have a material adverse effect on the condition (financial or
         otherwise), business, properties, financial position or results of
         operations of the Parent.

                  (ii) No consent, approval, authorization or order of, and no
         filing with, any court, regulatory body, government agency or other
         body, domestic or foreign, is required for the delivery and sale of the
         Securities pursuant to the Prospectus and the Registration Statement,
         the performance of this Agreement, and the transactions contemplated
         hereby, including without limitation, any waiver of any preemptive,
         first refusal or other rights that any entity or person may have for
         the delivery and sale of any of the Securities, except such as have
         been or may be obtained under the Act or may be required under state
         securities or Blue Sky laws in connection with the Underwriters'
         purchase and distribution of the Firm Securities and the Option
         Securities.

                  (iii) The Parent has not breached any of the representations
         and warranties contained in Section 1 of the Underwriting Agreement
         dated June 28, 1996 by and among the Parent, National and Bentley J.
         Blum (the "Parent Underwriting Agreement"), and is in compliance with

                  (iv) At the time when the Registration Statement becomes or
         became effective, and at all times subsequent thereto up to and
         including the Closing Date and the Option Closing Date, the
         Registration Statement and any amendments thereto will not contain any
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary in order to make the
         statements therein not misleading, and the Prospectus (and any
         supplements thereto) (or, if the Prospectus is not in existence, the
         most recent Preliminary Prospectus) will not contain any untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary in order to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading.

                  (v) Neither the Parent nor any of its employees, directors,
         stockholders, partners, or affiliates (within the meaning of the Rules
         and Regulations) of any of the foregoing has taken or will take,
         directly or indirectly, any action designed to or which has constituted
         or which might be expected to cause or result in, under the Exchange
         Act, or otherwise, stabilization or manipulation of the price of any
         security of the Company to facilitate the sale or resale of the
         Securities or otherwise.

                  (vi) There is not pending or, to the Parent's knowledge,
         threatened against the Parent any action, suit or proceeding which (A)
         questions the validity of this Agreement or of any action taken or to
         be taken by the Parent pursuant to or in connection with this
         Agreement, or (B) is required to be disclosed in the Registration
         Statement which is not so disclosed, and such actions, suits or
         proceedings as are summarized in the Registration Statement, if any,
         are accurately summarized.

                  (vii) The Parent has furnished the Representative and
         Underwriters' Counsel with a true and complete copy of the Parent SEC
         Documents. As used herein, the "Parent SEC Documents" shall mean all
         documents (other than preliminary material) that the Parent has filed
         or has been required to file with the Commission since January 1, 1996.
         As of its filing date (and, with respect to any registration statement,
         the date on which it or any post-effective amendment was declared
         effective) other than with respect to changes that may be necessitated
         by virtue of comments made by the Commission related to the

         Parent and its consolidated subsidiaries as of the dates thereof and
         the consolidated results of their operations for the periods presented.
         Since January 1, 1996, there has not been any change in the business,
         assets, condition, financial or otherwise, or results of operations of
         the Parent or any of its subsidiaries which might materially and
         adversely affect the condition, financial or otherwise, or the
         earnings, position, prospects, stockholders' equity, value, operation,
         properties, business or results of operations of the Company.

                  (viii) The Parent does not have any registration rights or
         other similar rights with respect to any securities of the Company; and
         the Parent does not have any right of first refusal or other similar
         right to purchase any securities of the Company upon the issuance or
         sale thereof by the Company or upon the sale thereof by any other
         stockholder of the Company.

                  (ix) The Parent has not since the filing of the initial
         Registration Statement (i) sold, bid for, purchased, attempted to
         induce any person to purchase, or paid anyone any compensation for
         soliciting purchases of Common Stock, or (ii) paid or agreed to pay to
         any person any compensation for soliciting another to purchase any
         securities of the Company (except as otherwise permitted by law).

                  (x) Any certificate signed by or on behalf of the Parent and
         delivered to the Underwriters shall be deemed a representation and
         warranty by the Parent to the Underwriters as to the matters covered
         thereby.

         2.  Purchase, Sale and Delivery of the Securities.

             (a) On the basis of the representations, warranties, covenants and
agreements herein contained, but subject to the terms and conditions herein set
forth, the Company agrees to sell to each Underwriter, and each Underwriter,
severally and not jointly, agrees to purchase from the Company at a price of
$_______ [92% of the public offering price] per Preferred Share, $_______ [92%
of the public offering price] per Common Share and $_______ [92% of the public
offering price] per Redeemable Warrant, that number of Firm Securities set forth
in Schedule A opposite the name of such Underwriter, subject to such adjustment
as the Representative in its sole discretion shall make to eliminate any sales
or purchases of fractional shares, plus any additional number of Firm Securities
which such Underwriter may become obligated to purchase pursuant to the
provisions of Section 11 hereof.

             (b) In addition, on the basis of the representations, warranties,
covenants and agreements herein contained, but subject to the terms and
conditions herein set forth, the Company hereby grants an option to the
Underwriters, severally and not jointly, to purchase all or any part of an
additional 225,000 shares of Convertible Preferred Stock at a price of $_______
[92% of the public offering price] per share of Convertible Preferred Stock,

                                     - 18 -

<PAGE>



public offering price] per Redeemable Warrant. The option granted hereby will
expire forty-five (45) days after (i) the date the Registration Statement
becomes effective, if the Company has elected not to rely on Rule 430A under the
Rules and Regulations, or (ii) the date of this Agreement if the Company has
elected to rely upon Rule 430A under the Rules and Regulations, and may be
exercised in whole or in part from time to time only for the purpose of covering
over-allotments which may be made in connection with the offering and
distribution of the Firm Securities upon notice by the Representative to the
Company setting forth the number of Option Securities as to which the several
Underwriters are then exercising the option and the time and date of payment and
delivery for any such Option Securities. Any such time and date of delivery (an
"Option Closing Date") shall be determined by the Representative, but shall not
be later than three (3) full business days after the exercise of said option,
nor in any event prior to the Closing Date, as hereinafter defined, unless
otherwise agreed upon by the Representative and the Company. Nothing herein
contained shall obligate the Underwriters to make any over-allotments. No Option
Securities shall be delivered unless the Firm Securities shall be simultaneously
delivered or shall theretofore have been delivered as herein provided.

             (c) Payment of the purchase price for, and delivery of certificates
for, the Firm Securities shall be made at the offices of the Representative at
1001 Fourth Avenue, Suite 2200, Seattle, Washington 98154, or at such other
place as shall be agreed upon by the Representative and the Company. Such
delivery and payment shall be made at 10:00 a.m. (New York City time) 
on ______________, 1997 or at such other time and date as shall be agreed upon
by the Representative and the Company, but not less than three (3) nor more than
five (5) full business days after the effective date of the Registration
Statement (such time and date of payment and delivery being herein called the
"Closing Date"). In addition, in the event that any or all of the Option
Securities are purchased by the Underwriters, payment of the purchase price for,
and delivery of certificates for, such Option Securities shall be made at the
above-mentioned office of the Representative or at such other place as shall be
agreed upon by the Representative and the Company on each Option Closing Date as
specified in the notice from the Representative to the Company. Delivery of the
certificates for the Firm Securities and the Option Securities, if any, shall be
made to the Underwriters against payment by the Underwriters, severally and not
jointly, of the purchase price for the Firm Securities and the Option
Securities, if any, to the order of the Company for the Firm Securities and the
Option Securities, if any, by New York Clearing House funds. In the event such
option is exercised, each of the Underwriters, acting severally and not jointly,
shall purchase that proportion of the total number of Option Securities then
being purchased which the number of Firm Securities set forth in Schedule A
hereto opposite the name of such Underwriter bears to the total number of Firm
Securities, subject in each case to such adjustments as the Representative in
its discretion shall make to eliminate any sales or purchases of fractional
shares. Certificates for the Firm Securities and the Option Securities, if any,
shall be in definitive, fully registered form, shall bear no restrictive legends
and shall be in such denominations and registered in such names as the
Underwriters may request in writing at least two (2) business days prior to the
Closing Date or the relevant Option Closing Date, as the case may be. The
certificates for the Firm Securities and the Option Securities, if any, shall be
made available to the Representative at such office or such other place as the
Representative may designate for inspection, checking and packaging no later
than 9:30


 
                                     - 19 -

<PAGE>



a.m. on the last business day prior to the Closing Date or the relevant Option
Closing Date, as the case may be.

             (d) On the Closing Date, the Company shall issue and sell to the
Representative Representative's Warrants at a purchase price of $.0001 per
warrant, which Representative's Warrants shall entitle the holders thereof to
purchase an aggregate of 150,000 shares of Convertible Preferred Stock, 150,000
shares of Common Stock and/or 300,000 Redeemable Warrants. The Representative's
Warrants shall be exercisable for a period of four (4) years commencing one (1)
year from the effective date of the Registration Statement at a price equaling
one hundred twenty percent (120%) of the respective initial public offering
price of the Preferred Shares, the Common Shares and the Redeemable Warrants.
The Representative's Warrant Agreement and form of Warrant Certificate shall be
substantially in the form filed as Exhibit 4.4 to the Registration Statement.
Payment for the Representative's Warrants shall be made on the Closing Date.

         3. Public Offering of the Preferred Shares, Common Shares and
Redeemable Warrants. As soon after the Registration Statement becomes effective
as the Representative deems advisable, the Underwriters shall make a public
offering of the Preferred Shares, the Common Shares and the Redeemable Warrants
(other than to residents of or in any jurisdiction in which qualification of the
Preferred Shares, the Common Shares and the Redeemable Warrants is required and
has not become effective) at the price and upon the other terms set forth in the
Prospectus. The Representative may from time to time increase or decrease the
respective public offering price after distribution of the Preferred Shares, the
Common Shares and the Redeemable Warrants has been completed to such extent as
the Representative, in its sole discretion, deems advisable. The Underwriters
may enter into one of more agreements as the Underwriters, in each of their sole
discretion, deem advisable with one or more broker-dealers who shall act as
dealers in connection with such public offering.

         4.  Covenants and Agreements of the Company and the Parent.

             (a) The Company covenants and agrees with each of the Underwriters
as follows:

                  (i) The Company shall use its best efforts to cause the
         Registration Statement and any amendments thereto to become effective
         as promptly as practicable and will not at any time, whether before or
         after the effective date of the Registration Statement, file any
         amendment to the Registration Statement or supplement to the Prospectus
         or file any document under the Act or Exchange Act before termination
         of the offering of the Preferred Shares, the Common Shares and the
         Redeemable Warrants by the Underwriters of which the Representative
         shall not previously have been advised and furnished with a copy, or to
         which the Representative shall have reasonably objected or which is not
         in compliance with the Act, the Exchange Act or the Rules and
         Regulations.

                  (ii) As soon as the Company is advised or obtains knowledge
         thereof, the Company will advise the Representative and confirm the
         notice in writing (i) when the


 
                                     - 20 -

<PAGE>



         Registration Statement, as amended, becomes effective, if the
         provisions of Rule 430A promulgated under the Act will be relied upon,
         when the Prospectus has been filed in accordance with said Rule 430A
         and when any post-effective amendment to the Registration Statement
         becomes effective; (ii) of the issuance by the Commission of any stop
         order or of the initiation, or the threatening, of any proceeding
         suspending the effectiveness of the Registration Statement or any order
         preventing or suspending the use of the Preliminary Prospectus or the
         Prospectus, or any amendment or supplement thereto, or the institution
         of proceedings for that purpose; (iii) of the issuance by the
         Commission or by any state securities commission of any proceedings for
         the suspension of the qualification of any of the Securities for
         offering or sale in any jurisdiction or of the initiation, or the
         threatening, of any proceeding for that purpose; (iv) of the receipt of
         any comments from the Commission; and (v) of any request by the
         Commission for any amendment to the Registration Statement or any
         amendment or supplement to the Prospectus or for additional
         information. If the Commission or any state securities commission shall
         enter a stop order or suspend such qualification at any time, the
         Company will use its best efforts to obtain promptly the lifting of
         such order.

                  (iii) The Company shall file the Prospectus (in form and
         substance satisfactory to the Representative) or transmit the
         Prospectus by a means reasonably calculated to result in filing with
         the Commission pursuant to Rule 424(b)(1) (or, if applicable and if
         consented to by the Representative, pursuant to Rule 424(b)(4)) not
         later than the Commission's close of business on the earlier of (i) the
         second business day following the execution and delivery of this
         Agreement and (ii) the fifth business day after the effective date of
         the Registration Statement.

                  (iv) The Company will give the Representative notice of its
         intention to file or prepare any amendment to the Registration
         Statement (including any post-effective amendment) or any amendment or
         supplement to the Prospectus (including any revised prospectus which
         the Company proposes for use by the Underwriters in connection with the
         offering of the Securities which differs from the corresponding
         prospectus on file at the Commission at the time the Registration
         Statement becomes effective, whether or not such revised prospectus is
         required to be filed pursuant to Rule 424(b) of the Rules and
         Regulations), and will furnish the Representative with copies of any
         such amendment or supplement a reasonable amount of time prior to such
         proposed filing or use, as the case may be, and will not file any such
         prospectus to which the Representative or Orrick, Herrington &
         Sutcliffe LLP ("Underwriters' Counsel") shall reasonably object.

                  (v) The Company shall endeavor in good faith, in cooperation
         with the Representative, at or prior to the time the Registration
         Statement becomes effective, to qualify the Securities for offering and
         sale under the securities laws of such jurisdictions as the
         Representative may designate to permit the continuance of sales and
         dealings therein for as long as may be necessary to complete the
         distribution, and shall make such applications, file such documents and
         furnish such information as may be required for such purpose; provided,
         however, the Company shall not be required to qualify as a


 
                                     - 21 -

<PAGE>



         foreign corporation or file a general or limited consent to service of
         process in any such jurisdiction. In each jurisdiction where such
         qualification shall be effected, the Company will, unless the
         Representative agrees that such action is not at the time necessary or
         advisable, use all reasonable efforts to file and make such statements
         or reports at such times as are or may reasonably be required by the
         laws of such jurisdiction to continue such qualification.

                  (vi) During the time when a prospectus is required to be
         delivered under the Act, the Company shall use all reasonable efforts
         to comply with all requirements imposed upon it by the Act and the
         Exchange Act, as now and hereafter amended and by the Rules and
         Regulations, as from time to time in force, so far as necessary to
         permit the continuance of sales of or dealings in the Securities in
         accordance with the provisions hereof and the Prospectus, or any
         amendments or supplements thereto. If at any time when a prospectus
         relating to the Securities is required to be delivered under the Act,
         any event shall have occurred as a result of which, in the reasonable
         opinion of counsel for the Company or Underwriters' Counsel, the
         Prospectus, as then amended or supplemented, includes an untrue
         statement of a material fact or omits to state any material fact
         required to be stated therein or necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading, or if it is necessary at any time to amend the
         Prospectus to comply with the Act, the Company will notify the
         Representative promptly and prepare and file with the Commission an
         appropriate amendment or supplement in accordance with Section 10 of
         the Act, each such amendment or supplement to be reasonably
         satisfactory to Underwriters' Counsel, and the Company will furnish to
         the Underwriters copies of such amendment or supplement as soon as
         available and in such quantities as the Underwriters may reasonably
         request.

                  (vii) As soon as practicable, but in any event not later than
         forty-five (45) days after the end of the 12-month period beginning on
         the day after the end of the fiscal quarter of the Company during which
         the effective date of the Registration Statement occurs (ninety (90)
         days in the event that the end of such fiscal quarter is the end of the
         Company's fiscal year), the Company shall make generally available to
         its security holders, in the manner specified in Rule 158(b) of the
         Rules and Regulations, and to the Representative, an earnings statement
         which will be in the detail required by, and will otherwise comply
         with, the provisions of Section 11(a) of the Act and Rule 158(a) of the
         Rules and Regulations, which statement need not be audited unless
         required by the Act, covering a period of at least twelve (12)
         consecutive months after the effective date of the Registration
         Statement.

             (viii) During a period of seven (7) years after the date hereof,
         the Company will furnish to its stockholders, as soon as practicable,
         annual reports (including financial statements audited by independent
         public accountants) and unaudited quarterly reports of earnings, and
         will deliver to the Representative:



 
                                     - 22 -

<PAGE>



                      (A) as soon as they are available, copies of all reports
                  (financial or other) mailed to stockholders;

                      (B) as soon as they are available, copies of all reports
                  and financial statements furnished to or filed with the
                  Commission, the NASD or any securities exchange;

                      (C) every press release and every material news item or
                  article of interest to the financial community in respect of
                  the Company, or its affairs, which was released or prepared by
                  or on behalf of the Company; and

                      (D) any additional information of a public nature
                  concerning the Company (and any future subsidiary) or its
                  businesses which the Representative may reasonably request.

             During such seven-year period, if the Company has an active
         subsidiary, the foregoing financial statements will be on a
         consolidated basis to the extent that the accounts of the Company and
         any of its subsidiaries are consolidated, and will be accompanied by
         similar financial statements for any significant subsidiary which is
         not so consolidated.

                  (ix) The Company will maintain a transfer agent and warrant
         agent ("Transfer Agent") and, if necessary under the jurisdiction of
         incorporation of the Company, a Registrar (which may be the same entity
         as the Transfer Agent) for its Convertible Preferred Stock, Common
         Stock and Redeemable Warrants.

                  (x) The Company will furnish to the Representative or on the
         Representative's order, without charge, at such place as the
         Representative may designate, copies of each Preliminary Prospectus,
         the Registration Statement and any pre-effective or post-effective
         amendments thereto (two of which copies will be signed and will include
         all financial statements and exhibits), the Prospectus, and all
         amendments and supplements thereto, including any prospectus prepared
         after the effective date of the Registration Statement, in each case as
         soon as available and in such quantities as the Representative may
         reasonably request.

                  (xi) On or before the effective date of the Registration
         Statement, the Company shall provide the Representative with true
         original copies of duly executed, legally binding and enforceable
         agreements pursuant to which, for a period of thirteen (13) months from
         the effective date of the Registration Statement, each of the Company's
         stockholders and holders of securities exchangeable or exercisable for
         or convertible into shares of Common Stock agrees that it or he or she
         (i) will not, directly or indirectly, issue, offer to sell, sell, grant
         an option for the sale or purchase of, assign, transfer, pledge,
         hypothecate or otherwise encumber or dispose of any shares of Common
         Stock or securities convertible into, exercisable or exchangeable for
         or evidencing any right to purchase or subscribe for any shares of
         Common Stock (either pursuant to Rule 144 of


 
                                     - 23 -

<PAGE>



         the Rules and Regulations or otherwise) or dispose of any beneficial
         interest therein without the prior consent of the Representative
         (collectively, the "Lock-up Agreements") and (ii) waives, during such
         thirteen (13) month period, any and all rights to request or demand the
         registration pursuant to the Act, of any securities of the Company
         which are registered in the name of or beneficially owned by it or he
         or she, respectively. During the thirteen (13) month period commencing
         on the effective date of the Registration Statement, the Company shall
         not, without the prior written consent of the Representative, sell,
         contract or offer to sell, issue, transfer, assign, pledge, distribute,
         or otherwise dispose of, directly or indirectly, any shares of Common
         Stock or any options, rights or warrants with respect to any shares of
         Common Stock. On or before the Closing Date, the Company shall deliver
         instructions to the Transfer Agent authorizing it to place appropriate
         legends on the certificates representing the securities subject to the
         Lock-up Agreements and to place appropriate stop transfer orders on the
         Company's ledgers.

                  (xii) Neither the Company nor any of its officers, directors,
         stockholders, nor any of its affiliates (within the meaning of the
         Rules and Regulations) will take, directly or indirectly, any action
         designed to, or which might in the future reasonably be expected to
         cause or result in, stabilization or manipulation of the price of any
         securities of the Company.

                  (xiii) The Company shall apply the net proceeds from the sale
         of the Firm Securities and the Option Securities, if any, in the
         manner, and subject to the conditions, set forth under "Use of
         Proceeds" in the Prospectus. No portion of the net proceeds will be
         used, directly or indirectly, to acquire any securities issued by the
         Company or any of its Affiliates (as defined herein).

                  (xiv) The Company shall timely file all such reports, forms or
         other documents as may be required (including, but not limited to, a
         Form SR as may be required pursuant to Rule 463 under the Act) from
         time to time, under the Act, the Exchange Act, and the Rules and
         Regulations, and all such reports, forms and documents filed will
         comply as to form and substance with the applicable requirements under
         the Act, the Exchange Act, and the Rules and Regulations.

                  (xv) The Company shall furnish to the Representative as early
         as practicable prior to each of the date hereof, the Closing Date and
         each Option Closing Date, if any, but no later than two (2) full

         interim financial statements of the Company (which in no event shall be
         as of a date more than thirty (30) days prior to the date of the
         Registration Statement) which have been read by the Company's
         independent public accountants, as stated in their letters to be
         furnished pursuant to Sections 6(l) and 6(m) hereof.

                  (xvi) The Company shall cause the Convertible Preferred Stock,

                  (xxi) For a period equal to the lesser of (i) seven (7) years
         from the date hereof, and (ii) the sale to the public of the
         Representative's Securities, the Company will not take any action or
         actions which may prevent or disqualify the Company's use of Form S-1
         (or other appropriate form) for the registration under the Act of the
         Representative's Securities. The Company further agrees to use its best
         efforts to file such post-effective amendments to the Registration
         Statement, as may be necessary, in order to maintain its effectiveness
         and to keep such Registration Statement effective while any of the
         shares of Convertible Preferred Stock, Redeemable Warrants or
         Representative's Warrants remain outstanding.

                  (xxii) Commencing one year and one day from the date hereof,
         if the Company engages the Representative as a warrant solicitation
         agent under the terms of the Warrant Agreement, the Company shall pay
         the Representative a commission equal to five percent (5%) of the
         exercise price of the Redeemable Warrants, payable on the date of the
         exercise thereof on the terms provided in the Warrant Agreement;
         provided, however, the Representative shall be entitled to receive the
         commission contemplated by this Section 4(a)(xxii) only if: (i) the
         Representative has provided actual services in connection with the
         solicitation of the exercise of a Redeemable Warrant by a Warrantholder
         and (ii) the Warrantholder exercising a Redeemable Warrant
         affirmatively designates in writing on the exercise form on the reverse
         side of the Redeemable Warrant Certificate that the exercise of such
         Warrantholder's Redeemable Warrant was solicited by the Representative.

                  (xxiii) Prior to the Closing Date, the Company shall have
         converted all short-term debt payable to the Parent (including any
         additional cash advances made by the Parent to the Company prior to the
         Closing Date which are not (or would not be) reflected as debt on the
         Company's balance sheet) into equity as partial consideration for the
         Company's previous issuance of 10,000,000 shares of Common Stock to the
         Parent.

                  (xxiv) The Company will not, and will not permit any of its
         future subsidiaries to, directly or indirectly, enter into any
         transaction or series of related transactions (including, but not
         limited to, the sale, purchase, exchange, lease, transfer or other
         disposition of any properties, assets or services to, or the purchase
         of any property, assets or services from, or the entry into any
         contract, agreement, undertaking, loan, advance or guarantee) with, or
         for the benefit of, an Affiliate (an "Affiliate Transaction"), or
         extend, renew, waive or otherwise modify the terms of any Affiliate
         Transaction entered into prior to the date of issuance of the
         Securities unless (i) such Affiliate Transaction is between or among
         the Company and its wholly-owned subsidiaries, or (ii) the terms of
         such Affiliate Transaction are fair and reasonable and at least as
         favorable to the Company or such subsidiary, as the case may be, as
         those that could have been obtained in a comparable arm's length
         transaction by the Company or such subsidiary with an unrelated person,
         and such Affiliate Transaction is entered into in the ordinary course
         of business of the parties thereto; provided, however, notwithstanding
         anything to the contrary contained herein, the Company may issue


 
                                     - 26 -

<PAGE>



         securities pursuant to the exercise of outstanding options and warrants
         on the terms in effect and described in the Prospectus relating to the
         Securities. All Affiliate Transactions must be approved in good faith
         by the Board of Directors of the Company and a minimum of three
         disinterested and independent outside directors thereof, and such
         approval evidenced by a Board Resolution that such transaction meets
         the criterion set forth in (i) or (ii) above. Affiliate includes
         Commodore and the Parent, each of their respective principal
         stockholders and subsidiaries, Bentley J. Blum and Paul E.
         Hannesson.

             (b) The Parent covenants and agrees with each of the Underwriters 
as follows:

                  (i) The Parent will not, directly or indirectly, without the
         prior written consent of the Company and the Representative, offer,
         offer to sell, sell, grant an option for the sale or purchase of,
         assign, transfer, pledge, hypothecate or otherwise encumber or dispose
         of any shares of Common Stock or any securities convertible into,
         exchangeable or exercisable for, or evidencing any right to purchase or
         subscribe for, any shares of Common Stock (either pursuant to Rule 144
         of the Rules and Regulations or otherwise) or dispose of any beneficial
         interest therein for a period of thirteen (13) months after the date
         hereof, except pursuant to this Agreement, and neither the Parent nor
         any of its officers, directors, stockholders, nor any of its affiliates
         (within the meaning of the Rules and Regulations) will take, directly
         or indirectly, any action designed to, or which might in the future
         reasonably be expected to cause or result in, stabilization or
         manipulation of the price of any securities of the Company.

                  (ii) The Parent consents to the use of the Prospectus and any
         amendment or supplement thereto by the Underwriters and all dealers to
         whom the Securities may be sold, both in connection with the offering
         or sale of the Securities and for such period of time thereafter as the
         Prospectus is required by law to be delivered in connection therewith.

                  (iii) The Parent will review the Prospectus and will comply
         with all agreements and satisfy all conditions on its part to be
         complied with or satisfied pursuant to this Agreement at or prior to
         any Closing Date or Option Closing Date, if any, and will advise the
         Company and the Representative prior to any Closing Date or Option
         Closing Date, if any, if any statement to be made on behalf of the
         Parent in the certificates contemplated by Section 6(j) hereof would be
         inaccurate if made as of such Closing Date or Option Closing Date, if
         any.

         5.  Payment of Expenses.

             (a) The Company hereby agrees to pay on each of the Closing Date
and the Option Closing Date (to the extent not paid at the Closing Date) all

         6. Conditions of the Underwriters' Obligations. The obligations of the
Underwriters hereunder shall be subject to the continuing accuracy of the

if they had been made on and as of the Closing Date or each Option Closing Date,
as the case may be; the accuracy on and as of the Closing Date or each Option
Closing Date, if any, of the statements of the officers of the Company and the

therein, in light of the circumstances under which they were made, not
misleading, or that the Prospectus, or any supplement thereto, contains an
untrue statement of fact which, in the Representative's reasonable opinion, is

             (c) On or prior to each of the Closing Date and each Option Closing
Date, if any, the Representative shall have received from Underwriters' Counsel,

validity of the Securities, the Registration Statement, the Prospectus and other
related matters as the Representative may request and Underwriters' Counsel
shall have received such papers and information as they request to enable them
to pass upon such matters.

             (d) At the Closing Date, the Underwriters shall have received the
favorable opinion of Greenberg, Traurig, Hoffman, Lipoff, Rosen & Quentel,
counsel to the Company, dated the Closing Date, addressed to the Underwriters
and in form and substance satisfactory to Underwriters' Counsel, to the effect
that:

                  (i) the Company (A) has been duly organized and is validly
         existing as a corporation in good standing under the laws of its
         jurisdiction, (B) is duly qualified and licensed and in good standing
         as a foreign corporation in each jurisdiction in which its ownership or
         leasing of any properties or the character of its operations requires
         such qualification or licensing, and (C) has all requisite corporate
         power and authority, and has obtained any and all necessary
         authorizations, approvals, orders, licenses, certificates, franchises
         and permits of and from all governmental or regulatory officials and
         bodies (including, without limitation, those having jurisdiction over
         environmental or similar matters), to own or lease its properties and
         conduct its business as described in the Prospectus; the Company is and
         has been doing business in compliance with all such authorizations,
         approvals, orders, licenses, certificates, franchises and permits and
         all federal, state and local laws, rules and regulations; and, the
         Company has not received any notice of proceedings relating to the
         revocation or modification of any such authorization, approval, order,
         license, certificate, franchise, or permit which, singly or in the
         aggregate, if the subject of an unfavorable decision, ruling or
         finding, would materially adversely affect the business, operations,
         condition, financial or otherwise, or the earnings, business affairs,
         position, prospects, value, operation, properties, or results of
         operations of the Company. The disclosures in the Registration
         Statement concerning the effects of federal, state and local laws,
         rules and regulations on the Company's business as currently conducted
         and as contemplated are correct in all material respects and do not
         omit to state a fact required to be stated therein or necessary to make
         the statements contained therein not misleading in light of the
         circumstances in which they were made.

                  (ii) the Company does not own an interest in any other
         corporation, partnership, joint venture, trust or other business
         entity;

                  (iii) the Company has a duly authorized, issued and
         outstanding capitalization as set forth in the Prospectus, and any
         amendment or supplement thereto, under "CAPITALIZATION", and, to the
         knowledge of such counsel, the Company is not a party to or bound by
         any instrument, agreement or other arrangement providing for it to
         issue, sell, transfer, purchase or redeem any capital stock, rights,
         warrants, options or


 
                                     - 30 -

<PAGE>



         other securities, except for this Agreement, the Warrant Agreement and
         the Representative's Warrant Agreement and as described in the
         Prospectus. The Securities and all other securities issued or issuable
         by the Company conform in all material respects to all statements with
         respect thereto contained in the Registration Statement and the
         Prospectus. All issued and outstanding securities of the Company have
         been duly authorized and validly issued and are fully paid and
         non-assessable; the holders thereof have no rights of rescission with
         respect thereto, and are not subject to personal liability by reason of
         being such holders; and none of such securities were issued in
         violation of the preemptive rights of any holders of any security of
         the Company or any similar rights granted by the Company. The
         Securities to be sold by the Company hereunder and under the Warrant
         Agreement and the Representative's Warrant Agreement are not and will
         not, to the knowledge of such counsel, be subject to any preemptive or
         other similar rights of any stockholder, have been duly authorized and,
         when issued, paid for and delivered in accordance with the terms
         hereof, will be validly issued, fully paid and non-assessable and
         conform to the description thereof contained in the Prospectus; the
         holders thereof will not be subject to any liability solely as such
         holders; all corporate action required to be taken for the
         authorization, issue and sale of the Securities has been duly and
         validly taken; and the certificates representing the Securities are in
         due and proper form. The Representative's Warrants and the Redeemable
         Warrants constitute valid and binding obligations of the Company to
         issue and sell, upon exercise thereof and payment therefor, the number
         and type of securities of the Company called for thereby. Upon the
         issuance and delivery pursuant to this Agreement of the Firm Securities
         and the Option Securities and the Representative's Warrants to be sold
         by the Company, the Underwriters and the Representative, respectively,
         will acquire good and marketable title to the Firm Securities and the
         Option Securities and the Representative's Warrants free and clear of
         any pledge, lien, charge, claim, encumbrance, pledge, security
         interest, or other restriction or equity of any kind whatsoever. No
         transfer tax is payable by or on behalf of the Underwriters in
         connection with (A) the issuance by the Company of the Securities, (B)
         the purchase by the Underwriters of the Firm Securities and the Option
         Securities from the Company, and the purchase by the Representative of
         the Representative's Warrants from the Company (C) the consummation by
         the Company of any of its obligations under this Agreement, the Warrant
         Agreement or the Representative's Warrant Agreement, or (D) resales of
         the Firm Securities and the Option Securities in connection with the
         distribution contemplated hereby.

                  (iv) the Registration Statement is effective under the Act,
         and, if applicable, filing of all pricing information has been timely
         made in the appropriate form under Rule 430A, and, to the best of such
         counsel's knowledge, no stop order suspending the use of the
         Preliminary Prospectus, the Registration Statement or Prospectus or any
         part of any thereof or suspending the effectiveness of the Registration
         Statement has been issued and no proceedings for that purpose have been
         instituted or are pending or, to the best of such counsel's knowledge,
         threatened or contemplated under the Act;



 
                                     - 31 -

                  (v) each of the Preliminary Prospectus, the Registration
         Statement, and the Prospectus and any amendments or supplements thereto
         (other than the financial statements and other financial and
         statistical data included therein, as to which no opinion need be
         rendered) comply as to form in all material respects with the
         requirements of the Act and the Rules and Regulations.

                  (vi) to the best of such counsel's knowledge, (A) there are no

         the Registration Statement (or required to be filed under the Exchange
         Act if upon such filing they would be incorporated, in whole or in

         Commodore, as the case may be, and its consolidated subsidiaries as of
         the dates thereof and the consolidated results of their operations for
         the periods presented. Since January 1, 1996, there has not been any
         change in the business, assets, condition, financial or otherwise, or

         or any of its subsidiaries which might materially and adversely affect
         the condition, financial or otherwise, or the earnings, position,
         prospects, stockholders' equity, value, operation, properties, business
         or results of operations of the Company.

         in the Prospectus under "CERTAIN RELATIONSHIPS AND RELATED
         TRANSACTIONS," there are no existing agreements, arrangements,
         understandings or transactions, or proposed agreements, arrangements,
         understandings or transactions, between or among the Company, and any
         officer, director, or 5% or greater securityholder of the Company, or
         any affiliate or associate of any such person or entity;

                  (xxiii) the Company is in compliance with all provisions of

         Company relating to any Hazardous Materials or the violation of any

         such approvals, authorizations, franchises, licenses, orders, permits,
         validations and certifications have been revoked, restricted or limited
         in any manner and all of such approvals, authorizations, franchises,
         licenses, orders, permits, validations and certifications are in full
         force and effect; and

         circumstances that may give rise to the same) involving the Company's
         production, use, testing, manufacturing or marketing of any products or
         services, which (i) questions the authority of the Company to produce,
         use, test, manufacture or market any products or services as described

qualified by, or that it is otherwise subject to, any treatise, written policy
or other document relating to legal opinions, including, without limitation, the

state accord.

             (k) By the Closing Date, the Underwriters will have received

             (l) At the time this Agreement is executed, the Underwriters shall
have received a letter, dated such date, addressed to the Underwriters in form
and substance satisfactory (including the non-material nature of the changes or
decreases, if any, referred to in clause (iii) below) in all respects to the
Underwriters and Underwriters' Counsel, from Tanner + Co.:

                  (i) confirming that they are independent certified public
         accountants with respect to the Company within the meaning of the Act
         and the applicable Rules and Regulations;

                  (ii) stating that it is their opinion that the financial
         statements and supporting schedules of the Company included in the
         Registration Statement comply as to form in all material respects with
         the applicable accounting requirements of the Act and the Rules and
         Regulations thereunder and that the Representative may rely upon the
         opinion of Tanner + Co. with respect to the financial statements and
         supporting schedules included in the Registration Statement;

                  (iii) stating that, on the basis of a limited review which
         included a reading of the latest available unaudited interim financial
         statements of the Company, a reading of the latest available minutes of
         the stockholders and board of directors and the various committees of
         the boards of directors of the Company, consultations with officers and
         other employees of the Company responsible for financial and accounting
         matters and other specified procedures and inquiries, nothing has come
         to their attention which would lead them to believe that (A) the
         unaudited financial statements and supporting schedules of the Company
         included in the Registration Statement do not comply as to form in all
         material respects with the applicable accounting requirements of the
         Act and the Rules and Regulations or are not fairly presented in
         conformity with generally accepted accounting principles applied on a
         basis substantially consistent with that of the audited financial
         statements of the Company included in the Registration Statement, or
         (B) at a


 
                                     - 41 -

<PAGE>



         specified date not more than five (5) days prior to the effective date
         of the Registration Statement, there has been any change in the capital
         stock or long-term debt of the Company, or any decrease in the
         stockholders' equity or net current assets or net assets of the Company
         as compared with amounts shown in the September 30, 1996 balance sheet
         included in the Registration Statement, other than as set forth in or
         contemplated by the Registration Statement, or, if there was any change
         or decrease, setting forth the amount of such change or decrease;

                  (iv) setting forth, at a date not later than five (5) days
         prior to the date of the Registration Statement, the amount of
         liabilities of the Company (including a break-down of commercial paper
         and notes payable to banks);

                  (v) stating that they have compared specific dollar amounts,
         numbers of shares, percentages of revenues and earnings, statements and
         other financial information pertaining to the Company set forth in the
         Prospectus in each case to the extent that such amounts, numbers,
         percentages, statements and information may be derived from the general
         accounting records, including work sheets, of the Company and excluding
         any questions requiring an interpretation by legal counsel, with the
         results obtained from the application of specified readings, inquiries
         and other appropriate procedures (which procedures do not constitute an
         examination in accordance with generally accepted auditing standards)
         set forth in the letter and found them to be in agreement;

                  (vi) statements as to such other matters incident to the
         transaction contemplated hereby as the Representative may request.

             (m) At the Closing Date and each Option Closing Date, if any, the
Underwriters shall have received from Tanner + Co. a letter, dated as of the
Closing Date or the Option Closing Date, as the case may be, to the effect that
they reaffirm that statements made in the letter furnished pursuant to
subsection (l) of this Section, except that the specified date referred to shall
be a date not more than five (5) days prior to the Closing Date or the Option
Closing Date, as the case may be, and, if the Company has elected to rely on
Rule 430A of the Rules and Regulations, to the further effect that they have
carried out procedures as specified in clause (v) of subsection (l) of this
Section with respect to certain amounts, percentages and financial information
as specified by the Representative and deemed to be a part of the Registration
Statement pursuant to Rule 430A(b) and have found such amounts, percentages and
financial information to be in agreement with the records specified in such
clause (v).

             (n) On each of the Closing Date and each Option Closing Date, if
any, there shall have been duly tendered to the Representative for the several
Underwriters' accounts the appropriate number of Securities.

             (o) No order suspending the sale of the Securities in any
jurisdiction designated by the Representative pursuant to subsection (a)(v) of
Section 4 hereof shall have been issued on


 
                                     - 42 -

either the Closing Date or the Option Closing Date, if any, and no proceedings
for that purpose shall have been instituted or shall be contemplated.

             (p) On or before the Closing Date, the Company shall have executed
and delivered to the Representative, (i) the Representative's Warrant Agreement
substantially in the form filed as Exhibit 4.4 to the Registration Statement, in
final form and substance satisfactory to the Representative, and (ii) the
Representative's Warrants in such denominations and to such designees as shall
have been provided to the Company.

             (q) On or before the Closing Date, the Firm Securities and Option
Securities shall have been duly approved for quotation on Nasdaq, subject to
official notice of issuance.

to the Representative all of the Lock-up Agreements, in form and substance
satisfactory to Underwriters' Counsel.

             (s) On or before the Closing Date, the Company shall have executed
and delivered to the Representative and the Transfer Agent the Warrant Agreement
substantially in the form filed as Exhibit 4.2 to the Registration Statement, in
final form and substance satisfactory to the Representative.

         If any condition to the Underwriters' obligations hereunder to be
fulfilled prior to or at the Closing Date or the relevant Option Closing Date,
as the case may be, is not so fulfilled, the Representative may terminate this
Agreement or, if the Representative so elects, it may waive any such conditions
which have not been fulfilled or extend the time for their fulfillment.

         7.  Indemnification.

             (a) The Company and the Parent, jointly and severally, agree to
indemnify and hold harmless each of the Underwriters (for purposes of this
Section 7 "Underwriter" shall include the officers, directors, partners,
employees, agents and counsel of the Underwriter, including specifically each
person who may be substituted for an Underwriter as provided in Section 11
hereof), and each person, if any, who controls the Underwriter ("controlling
person") within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act, from and against any and all losses, claims, damages, expenses or
liabilities, joint or several (and actions, proceedings, investigations,
inquiries, suits and litigation in respect thereof), whatsoever (including but
not limited to any and all expenses whatsoever reasonably incurred in
investigating, preparing or defending against any such claim, action,
proceeding, investigation, inquiry, suit or litigation, commenced or threatened,
or any claim whatsoever), as such are incurred, to which the Underwriter or such
controlling person may become subject under the Act, the Exchange Act or any
other statute or at common law or otherwise or under the laws of foreign
countries, arising out of or based upon (A) any untrue statement or alleged
untrue statement of a material fact contained (i) in any Preliminary Prospectus,
the Registration Statement or the Prospectus (as from time to time amended and
supplemented); (ii) in any post-effective amendment or amendments or any new
registration statement and prospectus in which is included securities of the
Company issued or issuable upon exercise of the Securities; or (iii) in any
application or other document or written communication (in this Section 7
collectively called "application") executed by the Company or based upon written
information furnished by the Company or the Parent in any jurisdiction in order
to qualify the Securities under the securities laws thereof or filed with the
Commission, any state securities commission or agency, Nasdaq or any other
securities exchange; (B) the omission or alleged omission therefrom of a
material fact required to be stated therein or necessary to make the statements
therein not misleading (in the case of the Prospectus, in the light of the
circumstances under which they were made), or (C) any breach of any
representation, warranty, covenant or agreement of the Company or the Parent
contained herein or in any certificate by or on behalf of the Company or any of
its officers or the Parent delivered pursuant hereto, unless, in the case of
clause (A) or (B) above, such statement or omission was made in reliance upon
and in strict conformity with written information furnished to the Company with
respect to any Underwriter by or on behalf of such Underwriter expressly for use
in any Preliminary Prospectus, the Registration Statement or Prospectus, or any
amendment thereof or supplement thereto, or in any application, as the case may
be.

         The foregoing indemnity with respect to any untrue statement contained
in or omission from a Preliminary Prospectus shall not inure to the benefit of
the Underwriter (or any person controlling such Underwriter) from whom the
person asserting any such loss, liability, claim, damage or expense purchased
any of the Firm Securities and/or Option Securities which are the subject
thereof if (1) the Company and/or the Parent sustains the burden of proving that
such asserting person did not receive a copy of the Prospectus (or the
Prospectus as amended or supplemented) (in each case exclusive of the documents
from which information is incorporated by reference) at or prior to the written
confirmation of the sale of such Firm Securities and/or


 
                                     - 44 -

<PAGE>



Option Securities to such person and the untrue statement contained in or
omitted from such Preliminary Prospectus was corrected in the Prospectus (or the
Prospectus as amended or supplemented) and (2) the Company shall have complied
with its covenant pursuant to Section 4(a)(vi) of this Agreement.

         Notwithstanding anything to the contrary contained herein, the Parent
shall not be required to make any payment in respect to any indemnification
obligation hereunder unless and until and then only to the extent that the
Representative shall determine, in its sole judgment, that the Company is unable
to make the subject indemnification payment.

         The indemnity agreement in this subsection (a) shall be in addition to
any liability which the Company or the Parent may have at common law or
otherwise.

             (b) Each of the Underwriters agrees severally, but not jointly, to
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the Registration Statement, and each other person, if
any, who controls the Company within the meaning of the Act, to the same extent
as the foregoing indemnity from the Company and the Parent to the Underwriters
but only with respect to statements or omissions, if any, made in any
Preliminary Prospectus, the Registration Statement or Prospectus or any
amendment thereof or supplement thereto or in any application made in reliance
upon, and in strict conformity with, written information furnished to the
Company with respect to any Underwriter by such Underwriter expressly for use in
such Preliminary Prospectus, the Registration Statement or Prospectus or any
amendment thereof or supplement thereto or in any such application, provided
that such written information or omissions only pertain to disclosures in the
Preliminary Prospectus, the Registration Statement or Prospectus directly
relating to the transactions effected by the Underwriters in connection with
this Offering. Each of the Company and the Parent acknowledges that the
statements with respect to the public offering of the Firm Securities and the
Option Securities set forth under the heading "Underwriting" and the
stabilization legend in the Prospectus have been furnished by the Underwriters
expressly for use therein and constitute the only information furnished in
writing by or on behalf of the Underwriters for inclusion in the Prospectus.

             (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any claim, action, suit,
investigation, inquiry, proceeding or litigation, such indemnified party shall,
if a claim in respect thereof is to be made against one or more indemnifying
parties under this Section 7, notify each party against whom indemnification is
to be sought in writing of the commencement thereof (but the failure so to
notify an indemnifying party shall not relieve it from any liability which it
may have under this Section 7 except to the extent that it has been prejudiced
in any material respect by such failure or from any liability which it may have
otherwise). In case any such claim, action, suit, investigation, inquiry,
proceeding or litigation is brought against any indemnified party, and it
notifies an indemnifying party or parties of the commencement thereof, the
indemnifying party or parties will be entitled to participate therein, and to
the extent it may elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to


 
                                     - 45 -

<PAGE>



assume the defense thereof with counsel reasonably satisfactory to such
indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such case
but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by the indemnifying parties in connection with
the defense thereof at the expense of the indemnifying party, (ii) the
indemnifying parties shall not have employed counsel reasonably satisfactory to
such indemnified party to have charge of the defense thereof within a reasonable
time after notice of commencement thereof, or (iii) such indemnified party or
parties shall have reasonably concluded that there may be defenses available to
it or them which are different from or additional to those available to one or
all of the indemnifying parties (in which case the indemnifying parties shall
not have the right to direct the defense thereof on behalf of the indemnified
party or parties), in any of which events such fees and expenses of one
additional counsel shall be borne by the indemnifying parties. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one claim, action, suit,
investigation, inquiry, proceeding or litigation or separate but similar or
related claims, actions, suits, investigations, inquiries, proceedings or
litigation in the same jurisdiction arising out of the same general allegations
or circumstances. Anything in this Section 7 to the contrary notwithstanding, an
indemnifying party shall not be liable for any settlement of any claim, action,
suit, investigation, inquiry, proceeding or litigation effected without its
written consent; provided, however, that such consent was not unreasonably
withheld. An indemnifying party will not, without the prior written consent of
the indemnified parties, settle, compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit,
investigation, inquiry, proceeding or litigation in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim, action, suit,
investigation, inquiry, proceeding or litigation), unless such settlement,
compromise or consent (i) includes an unconditional release of each indemnified
party from all liability arising out of such claim, action, suit, investigation,
inquiry, proceeding or litigation and (ii) does not include a statement as to or
an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

             (d) In order to provide for just and equitable contribution in any
case in which (i) an indemnified party makes claim for indemnification pursuant
to this Section 7, but it is judicially determined (by the entry of a final
judgment or decree by a court of competent jurisdiction and the expiration of
time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
the express provisions of this Section 7 provide for indemnification in such
case, or (ii) contribution under the Act may be required on the part of any
indemnified party, then each indemnifying party shall contribute to the amount
paid as a result of such losses, claims, damages, expenses or liabilities (or
actions in respect thereof) (A) in such proportion as is appropriate to reflect
the relative benefits received by each of the contributing parties, on the one
hand, and the party to be indemnified on the other hand, from the offering of
the Firm Securities and the Option Securities or (B) if the allocation provided
by clause (A) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above


 
                                     - 46 -

<PAGE>



but also the relative fault of each of the contributing parties, on the one
hand, and the party to be indemnified on the other hand in connection with the
statements or omissions that resulted in such losses, claims, damages, expenses
or liabilities, as well as any other relevant equitable considerations. In any
case where the Company and/or the Parent is the contributing party and the
Underwriters are the indemnified party, the relative benefits received by the
Company and/or the Parent, on the one hand, and the Underwriters, on the other,
shall be deemed to be in the same proportion as the total net proceeds from the
offering of the Firm Securities and the Option Securities (before deducting
expenses) bear to the total underwriting discounts received by the Underwriters
hereunder, in each case as set forth in the table on the Cover Page of the
Prospectus. Relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Parent, or by the Underwriters, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, expenses or
liabilities (or actions in respect thereof) referred to above in this subsection
(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this subsection (d), the
Underwriters shall not be required to contribute any amount in excess of the
underwriting discount applicable to the Firm Securities and the Option
Securities purchased by the Underwriters hereunder. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 7, (i) each person,
if any, who controls the Company within the meaning of the Act, each officer of
the Company who has signed the Registration Statement, and each director of the
Company shall have the same rights to contribution as the Company and (ii) each
person, if any, who controls an Underwriter within the meaning of the Act shall
have the same rights to contribution as such Underwriter, subject in each case
to this subsection (d). Any party entitled to contribution will, promptly after
receipt of notice of commencement of any action, suit or proceeding against such
party in respect to which a claim for contribution may be made against another
party or parties under this subsection (d), notify such party or parties from
whom contribution may be sought, but the omission so to notify such party or
parties shall not relieve the party or parties from whom contribution may be
sought from any obligation it or they may have hereunder or otherwise than under
this subsection (d), or to the extent that such party or parties were not
adversely affected by such omission. The contribution agreement set forth above
shall be in addition to any liabilities which any indemnifying party may have at
common law or otherwise.

         8. Representations and Agreements to Survive Delivery. All
representations, warranties and agreements contained in this Agreement or
contained in certificates of officers of the Company or the Parent submitted
pursuant hereto, shall be deemed to be representations, warranties and
agreements at the Closing Date and the Option Closing Date, as the case may be,
and such representations, warranties and agreements of the Company and the
Parent, as the case may be, and the indemnity agreements contained in Section 7
hereof, shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any Underwriter,


 
                                     - 47 -

<PAGE>



the Company, the Parent, any controlling person of any Underwriter or the
Company or the Parent, and shall survive termination of this Agreement or the
issuance and delivery of the Securities to the Underwriters and the
Representative, as the case may be.

         9. Effective Date. This Agreement shall become effective at 10:00 a.m.,
New York City time, on the next full business day following the date hereof, or
at such earlier time after the Registration Statement becomes effective as the
Representative, in its discretion, shall release the Securities for sale to the
public; provided, however, that the provisions of Sections 5, 7 and 10 of this
Agreement shall at all times be effective. For purposes of this Section 9, the
Securities to be purchased hereunder shall be deemed to have been so released
upon the earlier of dispatch by the Representative of telegrams to securities
dealers releasing such securities for offering or the release by the
Representative for publication of the first newspaper advertisement which is
subsequently published relating to the Securities.

         10. Termination.

             (a) Subject to subsection (b) of this Section 10, the
Representative shall have the right to terminate this Agreement, (i) if any
domestic or international event or act or occurrence has materially adversely
disrupted, or in the Representative's opinion will in the immediate future
materially adversely disrupt, the financial markets; or (ii) if any material
adverse change in the financial markets shall have occurred; or (iii) if trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange, Nasdaq, the NASD, the Boston Stock
Exchange, the Commission or any governmental authority having jurisdiction over
such matters; or (iv) if trading of any of the securities of the Company shall
have been suspended, or any of the securities of the Company shall have been
delisted, on any exchange or in any over-the-counter market; (v) if the United
States shall have become involved in a war or major hostilities, or if there
shall have been an escalation in an existing war or major hostilities or a
national emergency shall have been declared in the United States; or (vi) if a
banking moratorium has been declared by a state or federal authority; or (vii)
if a moratorium in foreign exchange trading has been declared; or (viii) if the
Company shall have sustained a loss material or substantial to the Company by
fire, flood, accident, hurricane, earthquake, theft, sabotage or other calamity
or malicious act which, whether or not such loss shall have been insured, will,
in the Representative's opinion, make it inadvisable to proceed with the
offering, sale and/or delivery of the Securities; or (ix) if there shall have
been such a material adverse change in the conditions or prospects of the
Company, or such material adverse change in the general market, political or
economic conditions, in the United States or elsewhere, that, in each case, in
the Representative's judgment, would make it inadvisable to proceed with the
offering, sale and/or delivery of the Securities or (x) if any of Paul E.
Hannesson, Carl O. Magnell, James M. DeAngelis and Srinivas Kilambi, Ph.D. shall
no longer serve the Company in their present capacity.

             (b) If this Agreement is terminated by the Representative in
accordance with the provisions of Section 10(a), the Company shall promptly
reimburse and indemnify the Representative for all of its actual out-of-pocket
expenses, including the reasonable fees and


 
                                     - 48 -

<PAGE>



disbursements of counsel for the Underwriters (less amounts previously paid
pursuant to Section 5(c) above). Notwithstanding any contrary provision
contained in this Agreement, if this Agreement shall not be carried out within
the time specified herein, or any extension thereof granted by the
Representative, by reason of any failure on the part of the Company or the
Parent to perform any undertaking or satisfy any condition of this Agreement by
it to be performed or satisfied (including, without limitation, pursuant to
Section 6 or Section 12) then, the Company shall promptly reimburse and
indemnify the Representative for all of its actual out-of-pocket expenses,
including the reasonable fees and disbursements of counsel for the Underwriters
(less amounts previously paid pursuant to Section 5(c) above). In addition, the
Company shall remain liable for all Blue Sky counsel fees and disbursements,
expenses and filing fees. Notwithstanding any contrary provision contained in
this Agreement, any election hereunder or any termination of this Agreement
(including, without limitation, pursuant to Sections 6, 10, 11 and 12 hereof),
and whether or not this Agreement is otherwise carried out, the provisions of
Section 5 and Section 7 shall not be in any way affected by such election or
termination or failure to carry out the terms of this Agreement or any part
hereof.

         11. Substitution of the Underwriters. If one or more of the
Underwriters shall fail (otherwise than for a reason sufficient to justify the
termination of this Agreement under the provisions of Section 6, Section 10 or
Section 12 hereof) to purchase the Securities which it or they are obligated to
purchase on such date under this Agreement (the "Defaulted Securities"), the
Representative shall have the right, within twenty-four (24) hours thereafter,
to make arrangement for one or more of the non-defaulting Underwriters, or any
other underwriters, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth; if, however, the Representative shall not have completed such
arrangements within such 24-hour period, then:

                  (a) if the number of Defaulted Securities does not exceed 10%
         of the total number of Firm Securities to be purchased on such date,
         the non-defaulting Underwriters shall be obligated to purchase the full
         amount thereof in the proportions that their respective underwriting
         obligations hereunder bear to the underwriting obligations of all
         non-defaulting Underwriters, or

                  (b) if the number of Defaulted Securities exceeds 10% of the
         total number of Firm Securities, this Agreement shall terminate without
         liability on the part of any non-defaulting Underwriters (or, if such
         default shall occur with respect to any Option Securities to be
         purchased on an Option Closing Date, the Underwriters may at the
         Representative's option, by notice from the Representative to the
         Company, terminate the Underwriters' obligation to purchase Option
         Securities from the Company on such date).

         No action taken pursuant to this Section 11 shall relieve any
defaulting Underwriter from liability in respect of any default by such
Underwriter under this Agreement.



 
                                     - 49 -

<PAGE>



         In the event of any such default which does not result in a termination
of this Agreement, the Representative shall have the right to postpone the
Closing Date or the Option Closing Date, as the case may be, for a period not
exceeding seven (7) days in order to effect any required changes in the
Registration Statement or Prospectus or in any other documents or arrangements.

         12. Default by the Company. If the Company shall fail at the Closing
Date or at any Option Closing Date, as applicable, to sell and deliver the
number of Securities which it is obligated to sell hereunder on such date, then
this Agreement shall terminate (or, if such default shall occur with respect to
any Option Securities to be purchased on an Option Closing Date, the
Underwriters may at the Representative's option, by notice from the
Representative to the Company, terminate the Underwriters' obligation to
purchase Option Securities from the Company on such date) without any liability
on the part of any non-defaulting party other than pursuant to Section 5,
Section 7 and Section 10 hereof. No action taken pursuant to this Section 12
shall relieve the Company from liability, if any, in respect of such default.

         13. Notices. All notices and communications hereunder, except as herein
otherwise specifically provided, shall be in writing and shall be deemed to have
been duly given if mailed or transmitted by any standard form of
telecommunication. Notices to the Underwriters shall be directed to the

         14. Parties. This Agreement shall inure solely to the benefit of and
shall be binding upon, the Underwriters, the Company, the Parent and the
controlling persons, directors and officers referred to in Section 7 hereof, and
their respective successors, legal representatives and assigns, and no other

or claim under or in respect of or by virtue of this Agreement or any provisions

                  said search certified to us as complete and accurate by
                  ________________ and current through ________________________,
                  1997 (no earlier than 5 days prior to the effective date of
                  the Registration Statement) and said jurisdictions being the
                  only jurisdictions in which filing of UCC financing statements
                  or other documents may be filed to effectively evidence a
                  security or other interest in said general intangibles; and

                  (viii) any and all records, documents, instruments and
                  agreements in our possession or under our control relating to
                  the Company or Commodore Membrane.

                  We have also examined such corporate records, documents,
instruments and agreements, and inquired into such other matters, as we have
deemed necessary or appropriate as a basis for the opinions set forth herein.
Whenever our opinion herein is qualified by the phrase "to the best of our
knowledge" or "to the best of our knowledge, after due inquiry," such language
means that, based upon (i) our inquiries of officers of the Company, (ii) our
review of the Documents, and (iii) our review of such other corporate records,
documents, instruments and agreements described in the first sentence of this
paragraph, we believe that such opinions are factually correct.

                  To the best of our knowledge, as to all matters of fact
represented to you by the Company, we advise you that nothing has come to our
attention that would cause us to believe that such facts are incorrect,
incomplete or misleading or that reliance thereon is not warranted under the
circumstances. We call to your attention that our opinion is limited to such
facts as

circumstances, fact or law subsequent thereto.

                  Based upon and subject to the foregoing, we are of the opinion

incorporated herein) and may have such

                                        6

<PAGE>

letters, numbers or other marks of identification or designation and such
legends, summaries or endorsements printed, lithographed or engraved thereon as
the Company may deem appropriate and as are not inconsistent with the provisions
of this Agreement, or as may be required to comply with any law or with any rule
or regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Warrants may be listed, or to conform to usage. The
Warrant Certificates shall be dated the date of issuance thereof (whether upon
initial issuance, transfer, exchange or in lieu of mutilated, lost, stolen or

case any officer of the Company who shall have signed any of the Warrant
Certificates shall cease to be such officer of the Company before the date of
issuance of the Warrant Certificates or before countersignature by the Warrant
Agent and issue and delivery thereof, such Warrant Certificates, nevertheless,
may be countersigned by the Warrant Agent, issued and delivered with the same
force and effect as though the person who signed such Warrant Certificates had
not ceased to be such officer of the Company. After countersignature by the
Warrant Agent, Warrant

                                        7

<PAGE>

Certificates shall be delivered by the Warrant Agent to the Registered Holder
promptly and without further action by the Company, except as otherwise provided
by Section 4(a) hereof.

                  SECTION 4.  Exercise.

                           (a) Warrants in denominations of one or whole number
multiples thereof may be exercised by the Registered Holder thereof commencing
at any time on or after the Initial Warrant Exercise Date, but not after the
Warrant Expiration Date, upon the terms and subject to the conditions set forth
herein and in the applicable Warrant Certificate. A Warrant shall be deemed to
have been exercised immediately prior to the close of business on the Exercise
Date and the person entitled to receive the securities deliverable upon such
exercise shall be treated for all purposes as the holder, upon exercise thereof,
as of the close of business on the Exercise Date. If Warrants in denominations
other than whole number multiples thereof shall be exercised at one time by the
same Registered Holder, the number of full shares of Common Stock which shall be
issuable upon exercise thereof shall be computed on the basis of the aggregate
number of full shares of Common Stock issuable upon such exercise. As soon as
practicable on or after the Exercise Date and in any event within five business
days after such date, if one or more Warrants have been exercised, the Warrant
Agent on behalf of the Company shall cause to be issued to the person or persons
entitled to receive the same a Common Stock certificate or certificates for the
shares of Common Stock deliverable upon such exercise, and the Warrant Agent
shall deliver the same to the person or persons entitled thereto. Upon the
exercise of any one or more Warrants, the Warrant Agent shall promptly notify
the Company in writing of such fact and of the number of securities delivered
upon such exercise and, subject to subsection (b) below, shall cause all
payments of an amount in cash or by check

                                        8

<PAGE>

made payable to the order of the Company, equal to the Purchase Price, to be
deposited promptly in the Company's bank account.

                           (b) At any time upon the exercise of any Warrants
after one year and one day from the date hereof, the Warrant Agent shall, on a
daily basis, within two business days after such exercise, notify National of
the exercise of any such Warrants and shall, on a weekly basis (subject to
collection of funds constituting the tendered Purchase Price, but in no event
later than five business days after the last day of the calendar week in which
such funds were tendered), remit to National an amount equal to five percent
(5%) of the Purchase Price of such Warrants then being exercised unless National
shall have notified the Warrant Agent that the payment of such amount with
respect to such Warrant is violative of the General Rules and Regulations
promulgated under the Exchange Act, or the rules and regulations of the NASD or
applicable state securities or "blue sky" laws, or the Warrants are those
underlying the Representative's Warrants in which event, the Warrant Agent shall
have to pay such amount to the Company; provided, that the Warrant Agent shall
not be obligated to pay any amounts pursuant to this Section 4(b) during any
week that such amounts payable are less than $1,000 and the Warrant Agent's
obligation to make such payments shall be suspended until the amount payable
aggregates $1,000, and provided further, that, in any event, any such payment
(regardless of amount) shall be made not less frequently than monthly.
Notwithstanding the foregoing, National shall be entitled to receive the
commission contemplated by this Section 4(b) as Warrant solicitation agent only
if: (i) National has provided actual services in connection with the
solicitation of the exercise of a Warrant by a Registered Holder and (ii) the
Registered Holder exercising a Warrant affirmatively designates in writing on
the exercise form on the

                                        9

<PAGE>

reverse side of the Warrant Certificate that the exercise of such Registered
Holder's Warrant was solicited by National.

                           (c) The Company shall not be required to issue
fractional shares on the exercise of Warrants. Warrants may only be exercised in
such multiples as are required to permit the issuance by the Company of one or
more whole shares. If one or more Warrants shall be presented for exercise in
full at the same time by the same Registered Holder, the number of whole shares
which shall be issuable upon such exercise thereof shall be computed on the
basis of the aggregate number of shares purchasable on exercise of the Warrants
so presented. If any fraction of a share would, except for the provisions
provided herein, be issuable on the exercise of any Warrant (or specified
portion thereof), the Company shall pay an amount in cash equal to such fraction
multiplied by the then current market value of a share of Common Stock,
determined as follows:

                  (1) If the Common Stock is quoted, listed, or admitted to
unlisted trading privileges, on Nasdaq or a national securities exchange, the
current market value of a share of Common Stock shall be the closing sale price
of the Common Stock at the end of the regular trading session on the last
business day prior to the date of exercise of the Warrants on whichever of such
exchanges had the highest average daily trading volume for the Common Stock on
such day; or

                  (2) If the Common Stock is not listed or admitted to unlisted
trading privileges on any national securities exchange, but is traded in the
over-the-counter market, the current market value of a share of Common Stock
shall be the average of the last reported bid and asked

                                       10

<PAGE>

prices of the Common Stock reported by the National Quotation Bureau, Inc. on
the last business day prior to the date of exercise of the Warrants;

                  (3) If the Common Stock is not quoted, listed, admitted to
unlisted trading privileges on Nasdaq or any national securities exchange, and
bid and asked prices of the Common Stock are not reported by the National
Quotation Bureau, Inc., the current market value of a share of Common Stock
shall be an amount, not less than the book value thereof as of the end of the
most recently completed fiscal quarter of the Company ending prior to the date
of exercise, determined by the members of the Board of Directors of the Company
exercising good faith and using customary valuation methods; or

                  (4) No Registered Holder of Warrants shall, as such, be
entitled to vote or to receive dividends or be deemed the holder of Common Stock
that may at any time be issuable upon exercise of such Warrants for any purpose
whatsoever, nor shall anything contained herein be construed to confer upon the
Registered Holder of Warrants, as such, any of the rights of a stockholder of
the Company or any right to vote for the election of directors or upon any
matter submitted to stockholders at any meeting thereof, or to give or withhold
consent to any corporate action (whether upon any recapitalization, issue or
reclassification of stock, change of par value or change of stock to no par
value, consolidation, merger or conveyance or otherwise), or to receive notice
of meetings, or to receive dividends or subscription rights, until such
Registered Holder shall have exercised such Warrants and been issued shares of
Common Stock in accordance with the provisions hereof.

                  SECTION 5. Reservation of Shares; Listing; Payment of Taxes;
etc.

                           (a) The Company covenants that it will at all times
reserve and keep available out of its authorized Common Stock, solely for the
purpose of issue upon exercise of Warrants, such number of shares of Common
Stock as shall then be issuable upon the exercise of all outstanding Warrants.
The Company covenants that all shares of Common Stock which shall be issuable
upon exercise of the Warrants shall, at the time of delivery thereof, be duly
and validly issued and fully paid and nonassessable and free from all preemptive
or similar rights, taxes, liens and charges with respect to the issue thereof,
and that upon issuance such shares shall be listed on each securities exchange,
if any, on which the other shares of outstanding Common Stock of the Company are
then listed.

                           (b) The Company covenants that if any securities to
be reserved for the purpose of exercise of Warrants hereunder require
registration with, or approval of, any governmental authority under any federal
securities law before such securities may be validly issued or delivered upon
such exercise, then the Company will file a registration statement under the
federal securities laws or a post-effective amendment, use its best efforts to
cause the same to become effective and to keep such registration statement
current while any of the Warrants are outstanding and deliver a prospectus which
complies with Section 10(a)(3) of the Act, to the Registered Holder exercising
the Warrant (except, if in the opinion of counsel to the Company, such
registration is not required under the federal securities law or if the Company
receives a letter from the staff of the Commission stating that it would not
take any enforcement action if such registration is not effected). The Company
will use its best efforts to obtain appropriate approvals or registrations under
state "blue sky" securities laws with respect to any such

                                       12

<PAGE>

securities. However, Warrants may not be exercised by, or shares of Common Stock
issued to, any Registered Holder in any state in which such exercise would be
unlawful.

                           (c) The Company shall pay all documentary, stamp or
similar taxes and other governmental charges that may be imposed with respect to
the issuance of Warrants, or the issuance or delivery of any shares of Common
Stock upon exercise of the Warrants; provided, however, that if shares of Common
Stock are to be delivered in a name other than the name of the Registered Holder
of the Warrant Certificate representing any Warrant being exercised, then no
such delivery shall be made unless the person requesting the same has paid to
the Warrant Agent the amount of transfer taxes or charges incident thereto, if
any.

                           (d) The Warrant Agent is hereby irrevocably
authorized as the Transfer Agent to requisition from time to time certificates
representing shares of Common Stock or other securities required upon exercise
of the Warrants, and the Company will comply with all such requisitions.

                  SECTION 6.  Exchange and Registration of Transfer.

                           (a) Warrant Certificates may be exchanged for other
Warrant Certificates representing an equal aggregate number of Warrants of the
same class or may be transferred in whole or in part. Warrant Certificates to be
exchanged shall be surrendered to the Warrant Agent at its Corporate Office,
and, upon satisfaction of the terms and provisions hereof, the Company shall
execute and the Warrant Agent shall countersign, issue and deliver in exchange
therefor the Warrant Certificate or Certificates which the Registered Holder
making the exchange shall be entitled to receive.

                                       13

<PAGE>

                           (b) The Warrant Agent shall keep, at its office,
books in which, subject to such reasonable regulations as it may prescribe, it
shall register Warrant Certificates and the transfer thereof in accordance with
customary practice. Upon due presentment for registration of transfer of any
Warrant Certificate at such office, the Company shall execute and the Warrant
Agent shall issue and deliver to the transferee or transferees a new Warrant
Certificate or Certificates representing an equal aggregate number of Warrants
of the same class.

                           (c) With respect to all Warrant Certificates
presented for registration of transfer, or for exchange or exercise, the
subscription or exercise form, as the case may be, on the reverse thereof shall
be duly endorsed or be accompanied by a written instrument or instruments of
transfer and subscription, in form satisfactory to the Company and the Warrant
Agent, duly executed by the Registered Holder thereof or his attorney-in-fact
duly authorized in writing.

                           (d) A service charge may be imposed by the Warrant
Agent for any exchange or registration of transfer of Warrant Certificates. In
addition, the Company may require payment by such Holder of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith.

                           (e) All Warrant Certificates surrendered for exercise
or for exchange in case of mutilated Warrant Certificates shall be promptly
canceled by the Warrant Agent and thereafter retained by the Warrant Agent until
termination of this Agreement or resignation as Warrant Agent (in which case
such Warrant Certificates shall be delivered to any successor warrant agent in
accordance with the provisions of Section 10 hereof).

                                       14

<PAGE>

                           (f) Prior to due presentment for registration of
transfer thereof, the Company and the Warrant Agent may deem and treat the
Registered Holder of any Warrant Certificate as the absolute owner thereof and
of each Warrant represented thereby (notwithstanding any notations of ownership
or writing thereon made by anyone other than a duly authorized officer of the
Company or the Warrant Agent) for all purposes and shall not be affected by any
notice to the contrary.

                  SECTION 7. Loss or Mutilation. Upon receipt by the Company and
the Warrant Agent of evidence satisfactory to them of the ownership of and the
loss, theft, destruction or mutilation of any Warrant Certificate and (in the
case of loss, theft or destruction) of indemnity satisfactory to them, and (in
case of mutilation) upon surrender and cancellation thereof, the Company shall
execute and the Warrant Agent shall (in the absence of notice to the Company
and/or the Warrant Agent that a new Warrant Certificate has been acquired by a
bona fide purchaser) countersign and deliver to the Registered Holder in lieu
thereof a new Warrant Certificate of like tenor representing an equal aggregate
number of Warrants. Applicants for a substitute Warrant Certificate shall also
comply with such other reasonable regulations and pay such other reasonable
charges as the Warrant Agent may prescribe.

                  SECTION 8.  Adjustment of Purchase Price and Number of Shares
of Common Stock Deliverable.

                           (a) Except as hereinafter provided, in the event the
Company shall, at any time or from time to time after the date hereof and prior
to the Warrant Expiration Date, issue or sell any shares of Common Stock for a
consideration per share less than the Purchase Price or issue any shares of
Common Stock as a stock dividend to the holders of Common Stock, or

                                       15

<PAGE>

subdivide or combine the outstanding shares of Common Stock into a greater or
lesser number of shares (any such issuance, subdivision or combination being
herein called a "Change of Shares"), then, and thereafter upon each further
Change of Shares, the Purchase Price for the Warrants (whether or not the same
shall be issued and outstanding) in effect immediately prior to such Change of
Shares shall be changed to a price (including any applicable fraction of a cent
to the nearest cent) determined by dividing (i) the sum of (x) the total number
of shares of Common Stock outstanding immediately prior to such Change of
Shares, multiplied by the Purchase Price in effect immediately prior to such
Change of Shares and (y) the consideration, if any, received by the Company upon
such sale, issuance, subdivision or combination, by (ii) the total number of
shares of Common Stock outstanding immediately after such Change of Shares;
provided, however, that in no event shall the Purchase Price be adjusted
pursuant to this computation to an amount in excess of the Purchase Price in
effect immediately prior to such computation, except in the case of a
combination of outstanding shares of Common Stock.

                  For the purposes of any adjustment to be made in accordance
with this Section 8(a), the following provisions shall be applicable:

                           (A) In case of the issuance or sale of shares of
Common Stock (or of other securities deemed hereunder to involve the issuance or
sale of shares of Common Stock) for a consideration part or all of which shall
be cash, the amount of the cash portion of the consideration therefor deemed to
have been received by the Company shall be (i) the subscription price, if shares
of Common Stock are offered by the Company for subscription, or (ii) the public
offering price (before deducting therefrom any compensation paid or discount
allowed in the sale, underwriting or purchase thereof by underwriters or dealers
or others

                                       16

<PAGE>

performing similar services, or any expenses incurred in connection therewith),
if such securities are sold to underwriters or dealers for public offering
without a subscription offering, or (iii) the gross amount of cash actually
received by the Company for such securities, in any other case.

                           (B) In case of the issuance or sale (otherwise than
as a dividend or other distribution on any stock of the Company, and otherwise
than on the exercise of options, rights or warrants or the conversion or
exchange of convertible or exchangeable securities) of shares of Common Stock
(or of other securities deemed hereunder to involve the issuance or sale of
shares of Common Stock) for a consideration part or all of which shall be other
than cash, the amount of the consideration therefor other than cash deemed to
have been received by the Company shall be the value of such consideration as
determined in good faith by the Board of Directors of the Company, using
customary valuation methods and on the basis of prevailing market values for
similar property or services.

                           (C) Shares of Common Stock issuable by way of
dividend or other distribution on any stock of the Company shall be deemed to
have been issued immediately after the opening of business on the day following
the record date for the determination of shareholders entitled to receive such
dividend or other distribution and shall be deemed to have been issued without
consideration.

                           (D) The reclassification of securities of the Company
other than shares of Common Stock into securities including shares of Common
Stock shall be deemed to involve the issuance of such shares of Common Stock for
a consideration other than cash immediately prior to the close of business on
the date fixed for the determination of security holders entitled to

                                       17

<PAGE>

receive such shares, and the value of the consideration allocable to such shares
of Common Stock shall be determined as provided in subsection (B) of this
Section 8(a).

                           (E) The number of shares of Common Stock at any one
time outstanding shall be deemed to include the aggregate maximum number of
shares issuable (subject to readjustment upon the actual issuance thereof) upon
the exercise of options, rights or warrants and upon the conversion or exchange
of convertible or exchangeable securities.

                           (b) Upon each adjustment of the Purchase Price
pursuant to this Section 8, the number of shares of Common Stock purchasable
upon the exercise of each Warrant shall be the number derived by multiplying the
number of shares of Common Stock purchasable immediately prior to such
adjustment by the Purchase Price in effect prior to such adjustment and dividing
the product so obtained by the applicable adjusted Purchase Price.

                           (c) In case the Company shall at any time after the
date hereof issue options, rights or warrants to subscribe for shares of Common
Stock, or issue any securities convertible into or exchangeable for shares of
Common Stock, for a consideration per share (determined as provided in Sections
8(a) and 8(b) and as provided below) less than the Purchase Price in effect
immediately prior to the issuance of such options, rights or warrants, or such
convertible or exchangeable securities, or without consideration (including the
issuance of any such securities by way of dividend or other distribution), the
Purchase Price for the Warrants (whether or not the same shall be issued and
outstanding) in effect immediately prior to the issuance of such options, rights
or warrants, or such convertible or exchangeable securities, as the case may be,
shall be reduced to a price determined by making the computation in accordance
with the provisions of Sections 8(a) and 8(b) hereof, provided that:

                                       18

<PAGE>

                           (A) The aggregate maximum number of shares of Common
Stock, as the case may be, issuable or that may become issuable under such
options, rights or warrants (assuming exercise in full even if not then
currently exercisable or currently exercisable in full) shall be deemed to be
issued and outstanding at the time such options, rights or warrants were issued,
for a consideration equal to the minimum purchase price per share provided for
in such options, rights or warrants at the time of issuance, plus the
consideration, if any, received by the Company for such options, rights or
warrants; provided, however, that upon the expiration or other termination of
such options, rights or warrants, if any thereof shall not have been exercised,
the number of shares of Common Stock deemed to be issued and outstanding
pursuant to this subsection (A) (and for the purposes of subsection (E) of
Section 8(a) hereof) shall be reduced by the number of shares as to which
options, warrants and/or rights shall have expired, and such number of shares
shall no longer be deemed to be issued and outstanding, and the Purchase Price
then in effect shall forthwith be readjusted and thereafter be the price that it
would have been had adjustment been made on the basis of the issuance only of
the shares actually issued plus the shares remaining issuable upon the exercise
of those options, rights or warrants as to which the exercise rights shall not
have expired or terminated unexercised.

                           (B) The aggregate maximum number of shares of Common
Stock issuable or that may become issuable upon conversion or exchange of any
convertible or exchangeable securities (assuming conversion or exchange in full
even if not then currently convertible or exchangeable in full) shall be deemed
to be issued and outstanding at the time of issuance of such securities, for a
consideration equal to the consideration received by the Company for such
securities, plus the minimum consideration, if any, receivable by the Company
upon the

                                       19

<PAGE>

conversion or exchange thereof; provided, however, that upon the termination of
the right to convert or exchange such convertible or exchangeable securities
(whether by reason of redemption or otherwise), the number of shares of Common
Stock deemed to be issued and outstanding pursuant to this subsection (B) (and
for the purposes of subsection (E) of Section 8(a) hereof) shall be reduced by
the number of shares as to which the conversion or exchange rights shall have
expired or terminated unexercised, and such number of shares shall no longer be
deemed to be issued and outstanding, and the Purchase Price then in effect shall
forthwith be readjusted and thereafter be the price that it would have been had
adjustment been made on the basis of the issuance only of the shares actually
issued plus the shares remaining issuable upon conversion or exchange of those
convertible or exchangeable securities as to which the conversion or exchange
rights shall not have expired or terminated unexercised.

                           (C) If any change shall occur in the price per share
provided for in any of the options, rights or warrants referred to in subsection
(A) of this Section 8(c), or in the price per share or ratio at which the
securities referred to in subsection (B) of this Section 8(c) are convertible or
exchangeable, such options, rights or warrants or conversion or exchange rights,
as the case may be, to the extent not theretofore exercised, shall be deemed to
have expired or terminated on the date when such price change became effective
in respect of shares not theretofore issued pursuant to the exercise or
conversion or exchange thereof, and the Company shall be deemed to have issued
upon such date new options, rights or warrants or convertible or exchangeable
securities.

                           (d) In case of any reclassification or change of
outstanding shares of Common Stock issuable upon exercise of the Warrants (other
than a change in par value, or

                                       20

<PAGE>

from par value to no par value, or from no par value to par value or as a result
of a subdivision or combination), or in case of any consolidation or merger of
the Company with or into another corporation (other than a merger with a
subsidiary of the Company in which merger the Company is the continuing
corporation) and which does not result in any reclassification or change of the
then outstanding shares of Common Stock or other capital stock issuable upon
exercise of the Warrants (other than a change in par value, or from par value to
no par value, or from no par value to par value or as a result of a subdivision
or combination) or in case of any sale or conveyance to another corporation of
the property of the Company as an entirety or substantially as an entirety,
then, as a condition of such reclassification, change, consolidation, merger,
sale or conveyance, the Company, or such successor or purchasing corporation, as
the case may be, shall make lawful and adequate provision whereby the Registered
Holder of each Warrant then outstanding shall have the right thereafter to
receive on exercise of such Warrant the kind and amount of securities and
property receivable upon such reclassification, change, consolidation, merger,
sale or conveyance by a holder of the number of securities issuable upon
exercise of such Warrant immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance and shall forthwith file at the
Corporate Office of the Warrant Agent a statement signed by its Chief Executive
Officer, President or a Vice President and by its Treasurer or an Assistant
Treasurer or its Secretary or an Assistant Secretary evidencing such provision.
Such provisions shall include provision for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in Sections
8(a), (b) and (c). The above provisions of this Section 8(d) shall similarly
apply to successive reclassifications and

                                       21

<PAGE>

changes of shares of Common Stock and to successive consolidations, mergers,
sales or conveyances.

                           (e) Irrespective of any adjustments or changes in the
Purchase Price or the number of shares of Common Stock purchasable upon exercise
of the Warrants, the Warrant Certificates theretofore and thereafter issued
shall, unless the Company shall exercise its option to issue new Warrant
Certificates pursuant to Section 2(d) hereof, continue to express the Purchase
Price per share and the number of shares purchasable thereunder as the Purchase
Price per share and the number of shares purchasable thereunder were expressed
in the Warrant Certificates when the same were originally issued.

                           (f) After each adjustment of the Purchase Price
pursuant to this Section 8, the Company will promptly prepare a certificate
signed by the Chairman, Chief Executive Officer or President, and by the
Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary,
of the Company setting forth: (i) the Purchase Price as so adjusted, (ii) the
number of shares of Common Stock purchasable upon exercise of each Warrant,
after such adjustment, and (iii) a brief statement of the facts accounting for
such adjustment. The Company will promptly file such certificate with the
Warrant Agent and cause a brief summary thereof to be sent by ordinary first
class mail to each Registered Holder at his last address as it shall appear on
the registry books of the Warrant Agent. No failure to mail such notice nor any
defect therein or in the mailing thereof shall affect the validity thereof
except as to the holder to whom the Company failed to mail such notice, or
except as to the holder whose notice was defective. The affidavit of an officer
of the Warrant Agent or the Secretary or an Assistant

                                       22

<PAGE>

Secretary of the Company that such notice has been mailed shall, in the absence
of fraud, be prima facie evidence of the facts stated therein.

                           (g) No adjustment of the Purchase Price shall be made
as a result of or in connection with (A) the issuance or sale of shares of
Common Stock pursuant to options, warrants, stock purchase agreements and
convertible or exchangeable securities outstanding or in effect on the date
hereof and on the terms described in the final prospectus relating to the public
offering contemplated by the Underwriting Agreement; or (B) the issuance or sale
of shares of Common Stock if the amount of said adjustment shall be less than
$.10, provided, however, that in such case, any adjustment that would otherwise
be required then to be made shall be carried forward and shall be made at the
time of and together with the next subsequent adjustment that shall amount,
together with any adjustment so carried forward, to at least $.10. In addition,
Registered Holders shall not be entitled to cash dividends paid by the Company
prior to the exercise of any Warrant or Warrants held by them.

                  SECTION 9. Redemption.

                           (a) Commencing on the Initial Warrant Redemption
Date, the Company may, on 30 days' prior written notice, redeem all, but not
less than all, of the Warrants at ten cents ($.10) per Warrant, provided,
however, that before any such call for redemption of Warrants can take place,
the average closing sale price for the Common Stock as reported by Nasdaq, if
the Common Stock is then traded on Nasdaq (or the average closing sale price, if
the Common Stock is then traded on another national securities exchange) shall
have equalled or exceeded $_____ per share [300% of the initial public offering
price of the Common Stock] for any twenty (20) trading days within a period of
thirty (30) consecutive trading days ending on

                                       23

<PAGE>

the fifth trading day prior to the date on which the notice contemplated by
subsections (b) and (c) below is given (subject to adjustment in the event of
any stock splits or other similar events as provided in Section 8 hereof).

                           (b) In case the Company shall exercise its right to
redeem any or all of the Warrants, it shall give or cause to be given notice to
the Registered Holders of the Warrants, by mailing to such Registered Holders a
notice of redemption, first class, postage prepaid, at their last address as
shall appear on the records of the Warrant Agent. Any notice mailed in the
manner provided herein shall be conclusively presumed to have been duly given
whether or not the Registered Holder receives such notice. Not less than five
(5) business days prior to the mailing to the Registered Holders of the Warrants
of the notice of redemption, the Company shall deliver or cause to be delivered
to National a similar notice telephonically and confirmed in writing together
with a list of the Registered Holders (including their respective addresses and
number of Warrants beneficially owned) to whom such notice of redemption has
been or will be given.

                           (c) The notice of redemption shall specify (i) the
Redemption Price, (ii) the Redemption Date, which shall in no event be less than
thirty (30) days after the date of mailing of such notice, (iii) the place where
the Warrant Certificate shall be delivered and the Redemption Price shall be
paid, (iv) if National is engaged as a Warrant solicitation agent, that National
shall receive the commission contemplated by Section 4(b) hereof, and (v) that
the right to exercise the Warrant shall terminate at 5:30 p.m. (New York time)
on the business day immediately preceding the date fixed for redemption. No
failure to mail such notice nor any defect therein or in the mailing thereof
shall affect the validity of the proceedings for such

                                       24

<PAGE>

redemption except as to a holder (a) to whom notice was not mailed or (b) whose
notice was defective. An affidavit of the Warrant Agent or the Secretary or
Assistant Secretary of the Company that notice of redemption has been mailed
shall, in the absence of fraud, be prima facie evidence of the facts stated
therein.

                           (d) Any right to exercise a Warrant shall terminate
at 5:30 p.m. (New York time) on the business day immediately preceding the
Redemption Date. The Redemption Price payable to the Registered Holders shall be
mailed to such persons at their addresses of record. On and after the Redemption
Date, Registered Holders of Warrants shall have no further rights except to
receive, upon surrender of the Warrant Certificate(s) representing such
Warrants, the Redemption Price.

                           (e) The Company shall indemnify National and each
person, if any, who controls National within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act against all loss, claim, damage,
expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which any
of them may become subject under the Act, the Exchange Act or otherwise, arising
from the registration statement or prospectus referred to in Section 5(b) hereof
to the same extent and with the same effect (including the provisions regarding
contribution) as the provisions pursuant to which the Company has agreed to
indemnify National contained in Section 7 of the Underwriting Agreement.

                           (f) Five business days prior to the Redemption Date,
the Company shall furnish to National (i) an opinion of counsel to the Company,
dated such date and addressed to National, and (ii) a "cold comfort" letter
dated such date addressed to National, signed by the

                                       25

<PAGE>

independent public accountants who have issued a report on the Company's
financial statements included in such registration statement, in each case
covering substantially the same matters with respect to such registration
statement (and the prospectus included therein) and, in the case of such
accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to underwriters in underwritten public
offerings of securities.

                  SECTION 10.  Concerning the Warrant Agent.

                           (a) The Warrant Agent acts hereunder as agent and in
a ministerial capacity for the Company and National, and its duties shall be
determined solely by the provisions hereof. The Warrant Agent shall not, by
issuing and delivering Warrant Certificates or by any other act hereunder, be
deemed to make any representations as to the validity or value or authorization
of the Warrant Certificates or the Warrants represented thereby or of any
securities or other property delivered upon exercise of any Warrant or whether
any stock issued upon exercise of any Warrant is fully paid and nonassessable.

                           (b) The Warrant Agent shall not at any time be under
any duty or responsibility to any holder of Warrant Certificates to make or
cause to be made any adjustment of the Purchase Price or the Redemption Price
provided in this Agreement, or to determine whether any fact exists which may
require any such adjustments, or with respect to the nature or extent of any
such adjustments, when made, or with respect to the method employed in making
the same. It shall not (i) be liable for any recital or statement of fact
contained herein or for any action taken, suffered or omitted by it in reliance
on any Warrant Certificate or other document or instrument believed by it in
good faith to be genuine and to have been signed or

                                       26

<PAGE>

presented by the proper party or parties, (ii) be responsible for any failure on
the part of the Company to comply with any of its covenants and obligations
contained in this Agreement or in any Warrant Certificate, or (iii) be liable
for any act or omission in connection with this Agreement except for its own
negligence, bad faith or willful misconduct.

                           (c) The Warrant Agent may at any time consult with
counsel satisfactory to it (who may be counsel for the Company or for National)
and shall incur no liability or responsibility for any action taken, suffered or
omitted by it in good faith in accordance with the opinion or advice of such
counsel.

                           (d) Any notice, statement, instruction, request,
direction, order or demand of the Company shall be sufficiently evidenced by an
instrument signed by the Chairman of the Board of Directors, Chief Executive
Officer, President or any Vice President (unless other evidence in respect
thereof is herein specifically prescribed). The Warrant Agent shall not be
liable for any action taken, suffered or omitted by it in accordance with such
notice, statement, instruction, request, direction, order or demand reasonably
believed by it to be genuine.

                           (e) The Company agrees to pay the Warrant Agent
reasonable compensation for its services hereunder and to reimburse it for its
reasonable expenses hereunder; the Company further agrees to indemnify the
Warrant Agent and save it harmless from and against any and all losses, expenses
and liabilities, including judgments, costs and counsel fees, for anything done
or omitted by the Warrant Agent in the execution of its duties and powers
hereunder except losses, expenses and liabilities arising as a result of the
Warrant Agent's negligence, bad faith or willful misconduct.

                           (f) The Warrant Agent may resign its duties and be
discharged from all further duties and liabilities hereunder (except liabilities
arising as a result of the Warrant Agent's own gross negligence or willful
misconduct), after giving 30 days' prior written notice to the Company. At least
15 days prior to the date such resignation is to become effective, the Warrant
Agent shall cause a copy of such notice of resignation to be mailed to the
Registered Holder of each Warrant Certificate at the Company's expense. Upon
such resignation, or any inability of the Warrant Agent to act as such
hereunder, the Company shall appoint in writing a new warrant agent. If the
Company shall fail to make such appointment within a period of 15 days after it
has been notified in writing of such resignation by the resigning Warrant Agent,
then the Registered Holder of any Warrant Certificate may apply to any court of
competent jurisdiction for the appointment of a new warrant agent. Any new
warrant agent, whether appointed by the Company or by such a court, shall be a
bank or trust company having a capital and surplus, as shown by its last
published report to its stockholders, of not less than $10,000,000 or a stock
transfer company that is a registered transfer agent under the Exchange Act.
After acceptance in writing of such appointment by the new warrant agent is
received by the Company, such new warrant agent shall be vested with the same
powers, rights, duties and responsibilities as if it had been originally named
herein as the Warrant Agent, without any further assurance, conveyance, act or
deed; but if for any reason it shall be necessary or expedient to execute and
deliver any further assurance, conveyance, act or deed, the same shall be done
at the expense of the Company and shall be legally and validly executed and
delivered by the resigning Warrant Agent. Not later than the effective date of
any such appointment the

                                       28

<PAGE>

Company shall file notice thereof with the resigning Warrant Agent and shall
forthwith cause a copy of such notice to be mailed to the Registered Holder of
each Warrant Certificate.

                           (g) Any corporation into which the Warrant Agent or
any new warrant agent may be converted or merged, any corporation resulting from
any consolidation to which the Warrant Agent or any new warrant agent shall be a
party, or any corporation succeeding to the corporate trust business of the
Warrant Agent or any new warrant agent shall be a successor warrant agent under
this Agreement without any further act, provided that such corporation is
eligible for appointment as successor to the Warrant Agent under the provisions
of the preceding paragraph. Any such successor warrant agent shall promptly
cause notice of its succession as warrant agent to be mailed to the Company and
to the Registered Holders of each Warrant Certificate.

                           (h) The Warrant Agent, its subsidiaries and
affiliates, and any of its or their officers or directors, may buy and hold or
sell Warrants or other securities of the Company and otherwise deal with the
Company in the same manner and to the same extent and with like effect as though
it were not Warrant Agent. Nothing herein shall preclude the Warrant Agent from
acting in any other capacity for the Company or for any other legal entity.

                           (i) The Warrant Agent shall retain for a period of
two years from the date of exercise any Warrant Certificate received by it upon
such exercise.

                  SECTION 11.  Modification of Agreement.

                  The Warrant Agent and the Company may by supplemental
agreement make any changes or corrections in this Agreement (i) that they shall
deem appropriate to cure any ambiguity or to correct any defective or
inconsistent provision or manifest mistake or error

                                       29

herein contained; or (ii) that they may deem necessary or desirable and which
shall not adversely affect the interests of the holders of Warrant Certificates;
provided, however, that this Agreement shall not otherwise be modified,
supplemented or altered in any respect except with the consent in writing of the
Registered Holders representing not less than 66-2/3% of the Warrants then
outstanding; provided, further, that no change in the number or nature of the
securities purchasable upon the exercise of any Warrant, or to increase the
Purchase Price therefor or to accelerate the Warrant Expiration Date, shall be
made without the consent in writing of the Registered Holder of the Warrant
Certificate representing such Warrant, other than such changes as are presently
specifically prescribed by this Agreement as originally executed. In addition,
this Agreement may not be modified, amended or supplemented without the prior
written consent of National, other than to cure any ambiguity or to correct any
provision which is inconsistent with any other provision of this Agreement or to
make any such change that is necessary or desirable and which shall not
adversely affect the interests of National and except as may be required by law.

                  SECTION 12.  Notices.

                  All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been made when
delivered or mailed first-class registered or certified mail, postage prepaid,

to the Company and the Warrant Agent in writing.

                  SECTION 13.  Governing Law.

                  This Agreement shall be governed by and construed in
accordance with the laws of the State of New York without giving effect to
conflicts of laws.

                  SECTION 14.  Binding Effect.

                  This Agreement shall be binding upon and inure to the benefit
of the Company, National, the Warrant Agent and their respective successors and
assigns and the holders from time to time of Warrant Certificates or any of
them. Nothing in this Agreement is intended or shall be construed to confer upon
any other person any right, remedy or claim, in equity or at law, or to impose
upon any other person any duty, liability or obligation.

                  SECTION 15.  Termination.

                  This Agreement shall terminate at the close of business on the
Expiration Date of all of the Warrants or such earlier date upon which all
Warrants have been exercised or redeemed, except that the Warrant Agent shall
account to the Company for cash held by it and the provisions of Section 10
hereof shall survive such termination.

                  SECTION 16.  Counterparts.

                  This Agreement may be executed in several counterparts, which
taken together shall constitute a single document.

THIS CERTIFIES THAT, FOR VALUE RECEIVED

or registered assigns (the "Registered Holder") is the owner of the number of
Redeemable Warrants (the "Warrants") specified above. Each Warrant initially
entitles the Registered Holder to purchase, subject to the terms and conditions
set forth in this Certificate and the Warrant Agreement (as hereinafter
defined), one fully paid and nonassessable share of Common Stock, $.001 par
value, of Commodore Separation Technologies, Inc., a Delaware corporation (the
"Company"), at any time between ___________________, 1998 (the "Initial Warrant
Exercise Date"), and the Expiration Date (as hereinafter defined) upon the
presentation and surrender of this Warrant Certificate with the Subscription
Form on the reverse hereof duly executed, at the corporate office of The Bank of
New York, as Warrant Agent, or its successor (the "Warrant Agent"), accompanied
by payment of $_____ per share of Common Stock, [140% of the initial public
offering price of the Common Stock] subject to adjustment (the "Purchase
Price"), in lawful money of the United States of America in cash or by check
made payable to the Warrant Agent for the account of the Company.

                This Warrant Certificate and each Warrant represented hereby are
issued pursuant to and are subject in all respects to the terms and conditions
set forth in the Warrant Agreement (the "Warrant Agreement"), dated ___________,
1997 [date of the Prospectus], between the Company, National Securities
Corporation ("National") and the Warrant Agent.

                In the event of certain contingencies provided for in the
Warrant Agreement, the Purchase Price and the number of shares of Common Stock
subject to purchase upon the exercise of each Warrant represented hereby are
subject to modification or adjustment.

                Each Warrant represented hereby is exercisable at the option of
the Registered Holder, but no fractional interests will be issued. In the case
of the exercise of less than all the

                                       A-1

<PAGE>

Warrants represented hereby, the Company shall cancel this Warrant Certificate
upon the surrender hereof and shall execute and deliver a new Warrant
Certificate or Warrant Certificates of like tenor, which the Warrant Agent shall
countersign, for the balance of such Warrants.

                The term "Expiration Date" shall mean 5:30 p.m. (New York time)
on __________, 2002 [forty-eight (48) months after the Initial Warrant Exercise
Date]. If each such date shall in the State of New York be a holiday or a day on
which the banks are authorized to close, then the Expiration Date shall mean
5:30 p.m. (New York time) on the next following day which in the State of New
York is not a holiday or a day on which banks are authorized to close.

                The Company shall not be obligated to deliver any securities
pursuant to the exercise of this Warrant unless a registration statement under
the Securities Act of 1933, as amended (the "Act"), with respect to such
securities is effective or an exemption thereunder is available. The Company has
covenanted and agreed that it will file a registration statement under the
Federal securities laws, use its best efforts to cause the same to become
effective, use its best efforts to keep such registration statement current, if
required under the Act, while any of the Warrants are outstanding, and deliver a
prospectus which complies with Section 10(a)(3) of the Act to the Registered
Holder exercising this Warrant. This Warrant shall not be exercisable by a
Registered Holder in any state where such exercise would be unlawful.

                This Warrant Certificate is exchangeable, upon the surrender
hereof by the Registered Holder at the corporate office of the Warrant Agent,
for a new Warrant Certificate or Warrant Certificates of like tenor representing
an equal aggregate number of Warrants, each of such new Warrant Certificates to
represent such number of Warrants as shall be designated by such Registered
Holder at the time of such surrender. Upon due presentment and payment of any
tax or other charge imposed in connection therewith or incident thereto, for
registration of transfer of this Warrant Certificate at such office, a new
Warrant Certificate or Warrant Certificates representing an equal aggregate
number of Warrants will be issued to the transferee in exchange therefor,
subject to the limitations provided in the Warrant Agreement.

                Prior to the exercise of any Warrant represented hereby, the
Registered Holder shall not be entitled to any rights of a stockholder of the
Company, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided in the Warrant
Agreement.

                Subject to the provisions of the Warrant Agreement, this Warrant
may be redeemed at the option of the Company, at a redemption price of $.10 per
Warrant, at any time commencing after ______________, 1998 [18 months after the
effective date of the Registration Statement], provided that the average closing
sale price for the Common Stock as reported by the Nasdaq SmallCap Market (or
the average closing sale price, if the Common Stock is then traded on another
national securities exchange), shall have equalled or exceeded $_____ per share
[300% of the initial public offering price of the Common Stock] for any twenty
(20) trading days within a period of thirty (30) consecutive trading days ending
on the fifth trading

                                       A-2

<PAGE>

day prior to the date of the Notice of Redemption, as defined below (subject to
adjustment in the event of any stock splits or other similar events). Notice of
redemption (the "Notice of Redemption") shall be given not later than the
thirtieth day before the date fixed for redemption, all as provided in the
Warrant Agreement. On and after the date fixed for redemption, the Registered
Holder shall have no rights with respect to the Warrants except to receive the
$.10 per Warrant upon surrender of this Warrant Certificate.

                Under certain circumstances, National may be entitled to receive
an aggregate of five percent (5%) of the Purchase Price of the Warrants
represented hereby.

                Prior to due presentment for registration of transfer hereof,
the Company and the Warrant Agent may deem and treat the Registered Holder as
the absolute owner hereof and of each Warrant represented hereby
(notwithstanding any notations of ownership or writing hereon made by anyone
other than a duly authorized officer of the Company or the Warrant Agent) for
all purposes and shall not be affected by any notice to the contrary, except as
provided in the Warrant Agreement.

                This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of New York without giving effect to
conflicts of laws.

                This Warrant Certificate is not valid unless countersigned by
the Warrant Agent.

                              W I T N E S S E T H:

                  WHEREAS, the Company proposes to issue to the Representative

<PAGE>



Stock, $____ per share of Common Stock and $.10 per Public Warrant (the "Public
Offering"); and

                  WHEREAS, the Warrants to be issued pursuant to this Agreement
will be issued on the Closing Date (as such term is defined in the Underwriting
Agreement) by the Company to the Representative in consideration for, and as

                  NOW, THEREFORE, in consideration of the premises, the payment
by the Representative to the Company of an aggregate fifteen dollars ($15.00),
the agreements herein set forth and other good and valuable consideration,
hereby acknowledged, the parties hereto agree as follows:

                  1. Grant. The Representative (and/or its designees) is hereby
granted the right to purchase, at any time from _______, 1998 [one year from the
effective date of the Registration Statement], until 5:30 P.M., New York time,
on _______, 2002 [five years from the effective date of the Registration
Statement], up to an aggregate of (a) 150,000 shares of Convertible Preferred
Stock (the "Preferred Shares") at an initial exercise price (subject to
adjustment as provided in Section 8 hereof) of $____ per share of Convertible
Preferred Stock [120% of the initial public offering price per share of
Convertible Preferred Stock], or in the event the Convertible Preferred Stock
has been redeemed by the Company or converted into shares of Common Stock in
accordance with the terms of the Convertible Preferred Stock, up to __________
shares (subject to adjustment as provided in Section 8 hereof) of Common Stock
(the "Conversion Shares") at an initial exercise price (subject to adjustment as
provided in


 
                                      - 2 -

<PAGE>



Section 8 hereof) of $_____ per share of Common Stock [120% of the initial
public offering price per share of Convertible Preferred Stock divided by the
then current Conversion Price, as defined in and calculated pursuant to that
certain Certificate of Designation, Preferences and Rights of 10% Senior
Convertible Redeemable Preferred Stock of Commodore Separation Technologies,
Inc. (the "Certificate of Designation"), dated as of ____________, 1997 and
filed with the Secretary of State of the State of Delaware], (b) 150,000 shares
of Common Stock (the "Common Shares") at an initial exercise price (subject to
adjustment as provided in Section 8 hereof) of $____ per share of Common Stock
[120% of the initial public offering price per share of Common Stock] and/or (c)
300,000 Redeemable Warrants at an initial exercise price (subject to adjustment
as provided in Section 8 hereof) of $____ per Redeemable Warrant [120% of the
initial public offering price per Redeemable Warrant], or any combination of
such Preferred Shares, Conversion Shares, Common Shares and/or Redeemable
Warrants at such exercise prices set forth herein, all subject to the terms and
conditions of this Agreement. One Redeemable Warrant is exercisable to purchase
one additional share of Common Stock at an initial exercise price of $_____
[140% of the initial public offering price per share of Common Stock] from
_______, 1998 [one year from the effective date of the registration statement]
until 5:30 p.m. New York time on _____, 2002 [five years from the effective date
of the registration statement], at which time the Redeemable Warrants shall
expire.

                  It is expressly understood that this Agreement entitles the
Representative to ten percent (10%) of the number of securities offered to the
public on an as converted basis (subject to adjustment as provided in Section 8
hereof). Therefore, in the case of the Warrants to purchase shares of
Convertible Preferred Stock, each share of Convertible Preferred Stock


 
                                      - 3 -

<PAGE>



purchased hereunder will reduce the number of Preferred Shares purchasable by
the Representative by ____ (__) (subject to adjustment as provided in Section 8
hereof). Similarly, each Conversion Share purchased hereunder will reduce the
number of Preferred Shares purchasable by the Representative by ____ of a share
of Convertible Preferred Stock and will reduce the number of Conversion Shares
purchasable by the Representative by one (subject to adjustment as provided in
Section 8 hereof). Except as set forth herein, the shares of Convertible
Preferred Stock, shares of Common Stock and Redeemable Warrants issuable upon
exercise of the Warrants are in all respects identical to the shares of
Convertible Preferred Stock, shares of Common Stock and Public Warrants being
purchased by the Underwriters for resale to the public pursuant to the terms and
provisions of the Underwriting Agreement. The Preferred Shares, the Conversion
Shares, the Common Shares and the Redeemable Warrants issuable upon exercise of
the Warrants are sometimes hereinafter referred to collectively as the
"Securities."

                  2. Warrant Certificates. The warrant certificates (the
"Warrant Certificates") delivered and to be delivered pursuant to this Agreement
shall be in the form set forth in Exhibit A, attached hereto and made a part
hereof, with such appropriate insertions, omissions, substitutions, and other
variations as required or permitted by this Agreement.

                  3.       Exercise of Warrant.

                  Section 3.1 Method of Exercise. The Warrants initially are
exercisable at an aggregate initial exercise price (subject to adjustment as
provided in Section 8 hereof) per Preferred Share, Conversion Share, Common
Share and Redeemable Warrant set forth in Section 6 hereof payable by certified
or official bank check in New York Clearing House funds, subject to adjustment
as


 
                                      - 4 -

<PAGE>



provided in Section 8 hereof. Upon surrender of a Warrant Certificate with the
annexed Form of Election to Purchase duly executed, together with payment of the
Exercise Price (as hereinafter defined) for the Preferred Shares, Conversion
Shares, Common Shares and/or Redeemable Warrants purchased at the Company's
principal executive offices in New York (presently located at 150 East 58th
Street, Suite 3400, New York, New York 10155) the registered holder of a Warrant
Certificate ("Holder" or "Holders") shall be entitled to receive a certificate
or certificates for the Securities so purchased. The purchase rights represented
by each Warrant Certificate are exercisable at the option of the Holder thereof,
in whole or in part (but not as to fractional shares of the Preferred Shares,
Conversion Shares, Common Shares and Redeemable Warrants underlying the
Warrants). In the event the Company redeems all of the shares of Convertible
Preferred Stock and/or Public Warrants (other than the Preferred Shares and
Redeemable Warrants underlying the Warrants), then the Warrants may only be
exercised if such exercise is accompanied by the simultaneous conversion of the
Preferred Shares and/or exercise of the Redeemable Warrants, as the case may be,
underlying the Warrants being so exercised. Warrants may be exercised to
purchase all or part of the Preferred Shares, Conversion Shares, Common Shares
and/or Redeemable Warrants purchasable thereunder. In the case of the purchase
of less than all the Securities purchasable under any Warrant Certificate, the
Company shall cancel said Warrant Certificate upon the surrender thereof and
shall execute and deliver a new Warrant Certificate of like tenor for the
balance of the Securities purchasable thereunder.

                  Section 3.2 Exercise by Surrender of Warrant. In addition to
the method of payment set forth in Section 3.1 and in lieu of any cash payment
required thereunder, the Holder(s) of


 
                                      - 5 -

<PAGE>



the Warrants shall have the right at any time and from time to time to exercise
the Warrants in full or in part by surrendering the Warrant Certificate in the
manner specified in Section 3.1 in exchange for the number of shares of Common
Stock equal to the quotient derived from dividing the numerator (x) an amount
equal to the difference between (A) the sum of (1) the number of Preferred
Shares as to which the Warrants are being exercised multiplied by the per
Preferred Share Market Price, (2) the number of Conversion Shares as to which
the Warrants are being exercised multiplied by the per Conversion Share Market
Price, (3) the number of Common Shares as to which the Warrants are being
exercised multiplied by the per Common Share Market Price, (4) the number of
Redeemable Warrants as to which the Warrants are being exercised multiplied by
the per Redeemable Warrant Market Price, and (5) the number of shares of Common
Stock issuable upon exercise of the Redeemable Warrants underlying the Warrants
being exercised multiplied by the per Common Share Market Price, and (B) the sum
of (1) the number of Warrants which are being exercised multiplied by the
Exercise Price, (2) the number of Preferred Shares included in the Warrants
which are being exercised multiplied by the Conversion Rate per Preferred Share
(as calculated pursuant to the Certificate of Designation) as then in effect,
and (3) the number of Redeemable Warrants included in the Warrants which are
being exercised multiplied by the exercise price per Redeemable Warrant (as
calculated pursuant to the Redeemable Warrant Agreement (hereinafter defined))
as then in effect, by the denominator (y) the per share Market Price of the
Common Stock. Solely for the purposes of this paragraph, Market Price shall be
calculated either (i) on the date on which the form of election attached hereto
is deemed to have been sent to the Company pursuant to Section 14


 
                                      - 6 -

<PAGE>



hereof ("Notice Date") or (ii) as the average of the Market Prices for each of
the five trading days preceding the Notice Date, whichever of (i) or (ii) is
greater.

                  Section 3.3 Definition of Market Price. As used herein, the
phrase "Market Price" at any date shall be deemed to be (i) when referring to
the Preferred Shares, the last reported sale price, or, in case no such reported
sale takes place on such day, the average of the last reported sale prices for
the last three (3) trading days, in either case as officially reported by the
Nasdaq SmallCap Market ("Nasdaq/SC") or the principal securities exchange on
which the Convertible Preferred Stock is listed or admitted to trading, or, if
the Convertible Preferred Stock is not listed or admitted to trading on
Nasdaq/SC or any national securities exchange or quoted by the National
Association of Securities Dealers Automated Quotation System ("Nasdaq"), the
average closing bid price as furnished by the National Association of Securities
Dealers, Inc. ("NASD") through Nasdaq or similar organization if Nasdaq is no
longer reporting such information, or if the Convertible Preferred Stock is not
quoted on Nasdaq, as determined in good faith (using customary valuation
methods) by resolution of the members of the Board of Directors of the Company,
based on the best information available to it; (ii) when referring to the
Conversion Shares or the Common Shares, the last reported sale price, or, in
case no such reported sale takes place on such day, the average of the last
reported sale prices for the last three (3) trading days, in either case as
officially reported by Nasdaq/SC or the principal securities exchange on which
the Common Stock is listed or admitted to trading, or, if the Common Stock is
not listed or admitted to trading on Nasdaq/SC or any national securities
exchange or quoted by Nasdaq, the average closing bid price as furnished by the
NASD through Nasdaq or similar organization if Nasdaq is no longer reporting
such information, or if the Common Stock is not quoted on


 
                                      - 7 -

<PAGE>



Nasdaq, as determined in good faith (using customary valuation methods) by
resolution of the members of the Board of Directors of the Company, based on the
best information available to it; or (iii) when referring to a Redeemable
Warrant, the last reported sale price, or, in the case no such reported sale
takes place on such day, the average of the last reported sale prices for the
last three (3) trading days, in either case as officially reported by Nasdaq/SC
or the principal securities exchange on which the Redeemable Warrants are listed
or admitted to trading, or, if the Redeemable Warrants are not listed or
admitted to trading on Nasdaq/SC or any national securities exchange or quoted
by Nasdaq, the average closing bid price as furnished by the NASD through Nasdaq
or similar organization if Nasdaq is no longer reporting such information, or if
the Redeemable Warrants are not quoted on Nasdaq or are no longer outstanding,
the Market Price of a Redeemable Warrant shall equal the difference between the
Market Price of the Common Stock and the Exercise Price of the Redeemable
Warrant.

                  4. Issuance of Certificates. Upon the exercise of the
Warrants, the issuance of certificates for the Securities and/or other
securities, properties or rights underlying such Warrants and, upon the
redemption or conversion of the Preferred Shares and/or the exercise of the
Redeemable Warrants, the issuance of certificates for shares of Common Stock
and/or other securities, properties or rights underlying such Preferred Shares
and/or Redeemable Warrants, as the case may be, shall be made forthwith (and in
any event within five (5) business days thereafter) without charge to the Holder
thereof including, without limitation, any tax which may be payable in respect
of the issuance thereof, and such certificates shall (subject to the provisions
of Sections 5 and 7 hereof) be issued in the name of, or in such names as may be
directed by, the Holder thereof; provided, however, that the Company shall not
be required to


 
                                      - 8 -

<PAGE>



pay any tax which may be payable in respect of any transfer involved in the
issuance and delivery of any such certificates in a name other than that of the
Holder, and the Company shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

                  The Warrant Certificates and the certificates representing the
Securities underlying the Warrants and the shares of Common Stock underlying the
Preferred Shares and Redeemable Warrants (and/or other securities, properties or
rights issuable upon the redemption or conversion of the Preferred Shares or the
exercise of the Warrants or the Redeemable Warrants) shall be executed on behalf
of the Company by the manual or facsimile signature of the then Chairman or Vice
Chairman of the Board of Directors or President or Vice President of the
Company. Warrant Certificates shall be dated the date of execution by the
Company upon initial issuance, division, exchange, substitution or transfer or
in lieu of mutilated, lost, stolen or destroyed Warrant Certificates.
Certificates representing the Securities, and the shares of Common Stock
underlying each Preferred Share and Redeemable Warrant (and/or other securities,
properties or rights issuable upon the redemption or conversion of the Preferred
Shares or exercise of the Warrants or the Redeemable Warrants) shall be dated as
of the Notice Date (regardless of when executed or delivered) and dividend
bearing securities so issued shall accrue dividends from the Notice Date.

                  5. Restriction On Transfer of Warrants. The Holder of a
Warrant Certificate, by its acceptance thereof, covenants and agrees that the
Warrants are being acquired as an investment and not with a view to the
distribution thereof; that the Warrants may not be sold,


 
                                      - 9 -

<PAGE>



transferred, assigned, hypothecated or otherwise disposed of, in whole or in
part, for a period of one (1) year from the date hereof, except to officers of
the Representative.

                  6. Exercise Price.

                  Section 6.1 Initial and Adjusted Exercise Price. Except as
otherwise provided in Section 8 hereof, the initial exercise price of each
Warrant shall be $____ [120% of the initial public offering price] per share of
Convertible Preferred Stock, $_____ [120% of the initial public offering price
per share of Convertible Preferred Stock divided by the then current Conversion
Price, as defined in and calculated pursuant to the Certificate of Designation]
per Conversion Share, $____ [120% of the initial public offering price] per
share of Common Stock and $_____ per Redeemable Warrant [120% of the initial
public offering price per Public Warrant]. The adjusted exercise price shall be
the price which shall result from time to time from any and all adjustments of
the initial exercise price in accordance with the provisions of Section 8
hereof. Any transfer of a Warrant shall constitute an automatic transfer and
assignment of the registration rights set forth in Section 7 hereof with respect
to the Securities or other securities, properties or rights underlying the
Warrants.

                  Section 6.2 Exercise Price. The term "Exercise Price" herein

                  7.       Registration Rights.

                  Section 7.1 Registration Under the Securities Act of 1933. The
Warrants, the Securities issuable upon exercise of the Warrants, the shares of
Common Stock issuable upon redemption or conversion of the Preferred Shares, the
shares of Common Stock issuable upon exercise of the Redeemable Warrants
underlying the Warrants and any of the other securities issuable upon redemption
or conversion of the Preferred Shares or exercise of the Warrants or Redeemable
Warrants (collectively, the "Warrant Securities") have been registered under the
Securities Act of 1933, as amended (the "Act"), pursuant to the Company's
Registration Statement on Form S-1 (Registration No. 333-11813) (the
"Registration Statement"). All of the representations and warranties of the
Company contained in the Underwriting Agreement relating to the Registration
Statement, the Preliminary Prospectus and Prospectus (as such terms are defined
in the Underwriting Agreement) and made as of the dates provided therein, are
incorporated by reference herein. The Company agrees and covenants promptly to
file post-effective amendments to such Registration Statement as may be
necessary in order to maintain its effectiveness and otherwise to take such
action as may be necessary to maintain the effectiveness of the Registration
Statement as long as any Warrants are outstanding. In the event that, for any
reason whatsoever, the Company shall fail to maintain the effectiveness of the
Registration Statement, the certificates representing the Warrant Securities
shall bear the following legend:

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended
                  ("Act"), and may not be offered or sold except pursuant to (i)
                  an effective registration statement under the Act, (ii) to the
                  extent applicable, Rule 144 under the Act (or any similar rule
                  under such Act relating to the disposition of securities), or
                  (iii) an opinion of


 
                                     - 11 -

<PAGE>



                  counsel, if such opinion shall be reasonably satisfactory to
                  counsel to the issuer, that an exemption from registration
                  under such Act is available.

                  Section 7.2 Piggyback Registration.

                  (a) If, at any time commencing after the date hereof and
expiring seven (7) years thereafter, the Company proposes to register any of its
securities under the Act (other than pursuant to Form S-4, Form S-8 or a
comparable registration statement) it will give written notice by registered
mail, at least thirty (30) days prior to the filing of each such registration
statement, to the Representative and to all other Holders of the Warrants and/or
the Warrant Securities of its intention to do so. If the Representative or other
Holders of the Warrants and/or Warrant Securities notify the Company within
twenty (20) business days after receipt of any such notice of its or their
desire to include any such securities in such proposed registration statement,
the Company shall afford the Representative and such Holders of the Warrants
and/or Warrant Securities the opportunity to have any such Warrant Securities
registered under such registration statement (a "Piggyback Registration");
provided, however, that the Representative and/or such Holders of the Warrants
and/or Warrant Securities shall furnish the Company with appropriate information
in connection therewith as the Company may request in writing.

                  (b) If, at any time after giving written notice of its
intention to register any securities in a Piggyback Registration but prior to
the effective date of the related registration statement, the Company shall
determine for any reason not to register such securities, the Company shall give
written notice of such determination to the Representative and to each Holder of
Warrants and/or Warrant Securities and, thereupon, shall be relieved of its
obligation


 
                                     - 12 -

<PAGE>



to register any Warrant Securities in connection with such Piggyback
Registration, irrespective of whether a written request for inclusion of any
such securities shall have been made. All best efforts obligations of the
Company pursuant to Section 7.4(a) shall cease if the Company determines to
terminate prior to such effective date any registration where Warrant Securities
are being registered pursuant to Section 7.2(a).

                  (c) If a Piggyback Registration involves an offering by or
through underwriters, then (i) the Representative and all Holders of Warrants
and/or Warrant Securities requesting to have their Warrant Securities included
in the Company's registration statement must sell their Warrant Securities to
the underwriters selected by the Company on the same terms and conditions as
apply to other selling shareholders and (ii) the Representative and any Holder
of Warrants and/or Warrant Securities requesting to have such Holder's Warrant
Securities included in such registration statement may elect in writing, not
later than three (3) business days prior to the effectiveness of the
registration statement filed in connection with such registration, not to have
such Holder's Warrant Securities so included in connection with such
registration.

                  (d) If a Piggyback Registration involves an offering by or
through underwriters, the Company shall not be required to include Warrant
Securities therein if and to the extent the underwriter managing the offering
reasonably believes in good faith and advises the Representative and each Holder
of Warrants and/or Warrant Securities requesting to have Warrant Securities
included in the Company's registration statement that such inclusion would
materially adversely affect such offering; provided that if other selling
shareholders, including employees, officers or directors of the Company, have
requested registration of


 
                                     - 13 -

<PAGE>



securities in the proposed offering, the Company will reduce or eliminate such
other selling shareholders' securities pro rata to the Warrant Securities in
proportion to the respective number of shares they have requested to be
registered, and in such event, the Representative and such Holders of Warrants
and/or Warrant Securities may delay any offering by them of all Warrant
Securities requested to be included or that portion of such Warrant Securities
eliminated for such period, not to exceed 60 days, as the managing underwriter
shall request, and the Company shall file such supplements and post-effective
amendments and take such other action necessary under Federal and State law or
regulation as may be necessary to permit the Representative and such Holders of
Warrants and/or Warrant Securities to make their proposed offering for a period
of 90 days following such period of delay.

                  Section 7.3 Demand Registration.

                  (a) At any time commencing after the date hereof and expiring
five (5) years thereafter, the Holders of the Warrants and/or Warrant Securities
representing a "Majority" (as hereinafter defined) of such securities (assuming
the exercise of all of the Warrants) shall have the right (which right is in
addition to the registration rights under Section 7.2 hereof), exercisable by
written notice to the Company, to have the Company prepare and file with the
Securities and Exchange Commission (the "Commission"), on one occasion only, a
registration statement and such other documents, including a prospectus, as may
be necessary in the opinion of both counsel for the Company and counsel for the
Representative and Holders, in order to comply with the provisions of the Act,
so as to permit a public offering and sale of their respective Warrant
Securities for nine (9) consecutive months by such Holders and any other Holders
of the Warrants and/or Warrant Securities who notify the Company within ten


 
                                     - 14 -

<PAGE>



(10) days after receiving notice from the Company of such request; provided,
however, the Company shall be entitled to defer such registration for a period
of up to 90 days if and to the extent that its Board of Directors shall
determine in good faith with an opinion of counsel for the Company that such
registration would interfere with a pending corporate transaction.

                  (b) The Company covenants and agrees to give written notice of
any registration request under this Section 7.3 by any Holder or Holders to all
other registered Holders of the Warrants and the Warrant Securities within ten
(10) days from the date of the receipt of any such registration request.

                  (c) In addition to the registration rights under Section 7.2
and subsection (a) of this Section 7.3, at any time commencing after the date
hereof and expiring five (5) years thereafter, any Holder of Warrants and/or
Warrant Securities shall have the right, exercisable by written request to the
Company, to have the Company prepare and file, on one occasion only, with the
Commission a registration statement so as to permit a public offering and sale
for nine (9) consecutive months by any such Holder of its Warrant Securities
provided, however, that the provisions of Section 7.4(b) hereof shall not apply
to any such registration request and registration and all costs incident thereto
shall be at the expense of the Holder or Holders making such request.

                  (d) Notwithstanding anything to the contrary contained herein,
if the Company shall not have filed a registration statement for the Warrant
Securities within the time period specified in Section 7.4(a) hereof pursuant to
the written notice specified in Section 7.3(a) of a Majority of the Holders of

7.3(a) or (y) the expiration of the period specified in Section 7.4(a) and (ii)
any and all Warrants of such Holders at such Market Price less the Exercise

election specified in this Section 7.3(d).

                  Section 7.4 Covenants of the Company With Respect to

registration statement will pay all costs, fees and expenses in connection with
any registration statement filed pursuant to Section 7.3(c).

                  (c) The Company will take all necessary action which may be
required in qualifying or registering the Warrant Securities included in a
registration statement for offering and sale under the securities or blue sky
laws of such states as reasonably are requested by the Holder(s), provided that
the Company shall not be obligated to execute or file any general consent to
service of process or to qualify as a foreign corporation to do business under
the laws of any such jurisdiction.

                  (d) The Company shall indemnify the Holder(s) of the Warrant
Securities to be sold pursuant to any registration statement and each person, if
any, who controls such Holders within the meaning of Section 15 of the Act or
Section 20(a) of the Securities Exchange Act of 1934, as amended ("Exchange
Act"), against all loss, claim, damage, expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify each of the Underwriters contained in Section 7
of the Underwriting Agreement.

                  (e) The Holder(s) of the Warrant Securities to be sold
pursuant to a registration statement, and their successors and assigns, shall
severally, and not jointly, indemnify the Company, its officers and directors
and each person, if any, who controls the Company within the meaning of Section

in investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holders, or their successors
or assigns, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in Section 7 of the
Underwriting Agreement pursuant to which the Underwriters have agreed to
indemnify the Company.

                  (f) Nothing contained in this Agreement shall be construed as
requiring the Holder(s) to exercise their Warrants prior to the initial filing
of any registration statement or the effectiveness thereof.

                  (g) The Company shall not permit the inclusion of any
securities other than the Warrant Securities to be included in any registration
statement filed pursuant to Section 7.3 hereof, or permit any other registration
statement to be or remain effective during the effectiveness of a registration
statement filed pursuant to Section 7.3 hereof, without the prior written
consent of the Holders of the Warrants and Warrant Securities representing a
Majority of such securities, which consent shall not be unreasonably withheld.

                  (h) The Company shall furnish to each Holder participating in
the offering and to each underwriter, if any, a signed counterpart, addressed to
such Holder or underwriter, of (i) an opinion of counsel to the Company, dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, an opinion dated the date of the
closing under the underwriting agreement), and (ii) a "cold comfort" letter
dated the effective date of such registration statement (and, if such
registration includes an underwritten public offering, a letter dated the date

agreement) signed by the independent public accountants who have issued a report
on the Company's financial statements included in such registration statement,
in each case covering substantially the same matters with respect to such
registration statement (and the prospectus included therein) and, in the case of
such accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to underwriters in underwritten public
offerings of securities.

                  (i) The Company shall as soon as practicable after the
effective date of the registration statement, and in any event within 15 months
thereafter, make "generally available to its security holders" (within the
meaning of Rule 158 under the Act) an earnings statement (which need not be
audited) complying with Section 11(a) of the Act and covering a period of at
least 12 consecutive months beginning after the effective date of the
registration statement.

                  (j) The Company shall deliver promptly to each Holder
participating in the offering requesting the correspondence and memoranda
described below and to the managing underwriters, copies of all correspondence
between the Commission and the Company, its counsel or auditors and all
memoranda relating to discussions with the Commission or its staff with respect
to the registration statement and permit each Holder and underwriter to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems reasonably
necessary to comply with applicable securities laws or rules of the NASD. Such
investigation shall include access to books, records and properties and
opportunities to discuss the business of the Company with


 
                                     - 19 -

<PAGE>



its officers and independent auditors, all to such reasonable extent and at such
reasonable times and as often as any such Holder or underwriter shall reasonably
request.

                  (k) The Company shall enter into an underwriting agreement
with the managing underwriters selected for such underwriting by Holders holding
a Majority of the Warrant Securities requested to be included in such
underwriting, which may be the Representative. Such agreement shall be
satisfactory in form and substance to the Company, each Holder and such managing
underwriter(s), and shall contain such representations, warranties and covenants
by the Company and such other terms as are customarily contained in agreements
of that type used by the managing underwriter(s). The Holders shall be parties
to any underwriting agreement relating to an underwritten sale of their Warrant
Securities and may, at their option, require that any or all of the
representations, warranties and covenants of the Company to or for the benefit
of such underwriter(s) shall also be made to and for the benefit of such
Holders. Such Holders shall not be required to make any representations or
warranties to or agreements with the Company or the underwriter(s) except as
they may relate to such Holders and their intended methods of distribution.

                  (l) In addition to the Warrant Securities, upon the written
request therefor by any Holder(s), the Company shall include in the registration
statement any other securities of the Company held by such Holder(s) as of the
date of filing of such registration statement, including without limitation
restricted shares of Convertible Preferred Stock, Common Stock, options,
warrants or any other securities convertible into shares of Common Stock.

                  (m) For purposes of this Agreement, the term "Majority" in
reference to the Holders of Warrants or Warrant Securities, shall mean in excess
of fifty percent (50%) of the


 
                                     - 20 -

<PAGE>



then outstanding Warrants or Warrant Securities that (i) are not held by the
Company, an affiliate, officer, creditor, employee or agent thereof or any of
their respective affiliates, members of their family, persons acting as nominees
or in conjunction therewith and (ii) have not been resold to the public pursuant
to a registration statement filed with the Commission under the Act.

                  8. Adjustments to Exercise Price and Number of Securities.

                  Section 8.1 Subdivision and Combination. In case the Company
shall at any time subdivide or combine the outstanding shares of Convertible
Preferred Stock or Common Stock, the Exercise Price shall forthwith be
proportionately decreased in the case of subdivision or increased in the case of
combination.

                  Section 8.2 Stock Dividends and Distributions. In case the
Company shall pay a dividend in, or make a distribution of, shares of
Convertible Preferred Stock, Common Stock or of the Company's capital stock
convertible into Common Stock, the Exercise Price shall forthwith be
proportionately decreased. An adjustment made pursuant to this Section 8.2 shall
be made as of the record date for the subject stock dividend or distribution.

                  Section 8.3 Adjustment in Number of Securities. Upon each
adjustment of the Exercise Price pursuant to the provisions of this Section 8,
the number of Warrant Securities issuable upon the exercise at the adjusted
exercise price of each Warrant shall be adjusted to the nearest full amount by
multiplying a number equal to the Exercise Price in effect immediately prior to
such adjustment by the number of Warrant Securities issuable upon exercise of
the Warrants immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

<PAGE>



                  Section 8.4 Definition of Common Stock and Convertible
Preferred Stock. (a) For the purpose of this Agreement, the term "Common Stock"
shall mean (i) the class of stock designated as Common Stock in the Certificate
of Incorporation of the Company as may be amended as of the date hereof, or (ii)
any other class of stock resulting from successive changes or reclassifications
of such Common Stock consisting solely of changes in par value, or from par
value to no par value, or from no par value to par value. In the event that the
Company shall after the date hereof issue securities with greater or superior
voting rights than the shares of Common Stock outstanding as of the date hereof,
the Holder, at its option, may receive upon exercise of any Warrant either the
Warrant Securities or a like number of such securities with greater or superior
voting rights.

                  (b) For the purpose of this Agreement, the term "Convertible
Preferred Stock" shall mean the Convertible Preferred Stock purchased by the
Underwriters for resale to the public in the Public Offering pursuant to the
terms of the Underwriting Agreement, as such Convertible Preferred Stock is more
particularly described in the Certificate of Designation, as the same may be
amended from time to time. The Preferred Shares issuable upon exercise of the
Warrants shall be identical to the Convertible Preferred Stock described in the
Certificate of Designation except that such Preferred Shares cannot be redeemed.
In the event of any change after the date hereof in the Conversion Rate (as
defined in and calculated pursuant to the Certificate of Designation) or, the
time period for conversion of, or the number or class of securities issuable
upon conversion of, the Convertible Preferred Stock, the Holder of any Warrant
shall receive upon exercise thereof Preferred Shares with a conversion ratio
(and an effective conversion price) equal to the Conversion Rate (and an
effective Conversion


 
                                     - 22 -

<PAGE>



Price) then in effect for, convertible for such number and class of securities
as would be issuable upon the conversion of, and convertible for such period of
time as, shares of Convertible Preferred Stock issued and outstanding on the
date hereof after giving effect to such change. In addition, in the event that
the Company grants to the holders of Convertible Preferred Stock upon the
conversion thereof any benefits or inducements not set forth in the Certificate
of Designation, the Holder shall be entitled to receive such benefit or
inducement upon the exercise by such Holder of any Warrant(s) to purchase
Preferred Shares or Conversion Shares.

                  Section 8.5 Merger or Consolidation. In case of any
consolidation of the Company with, or merger of the Company with, or merger of
the Company into, another corporation (other than a consolidation or merger
which does not result in any reclassification or change of the outstanding
Common Stock or Convertible Preferred Stock or other securities issuable upon
exercise of the Warrants or Redeemable Warrants or redemption or conversion of
the Convertible Preferred Stock), or in the case of any sale or conveyance to
another person, corporation or other entity of the property of the Company as an
entirety or substantially as an entirety, then, as a condition of such
consolidation, merger, sale or conveyance, the Company or such successor or
purchasing entity, as the case may be, shall execute and deliver to the Holder a
supplemental warrant agreement providing that the holder of each Warrant then
outstanding or to be outstanding shall have the right thereafter (until the
expiration of such Warrant) to receive, upon exercise of such Warrant, the kind
and amount of shares of stock and other securities and property receivable upon
such consolidation or merger, by a holder of the number of securities of the
Company for which such Warrant might have been exercised


 
                                     - 23 -

<PAGE>



immediately prior to such consolidation, merger, sale or transfer. Such
supplemental warrant agreement shall provide for adjustments which shall be
identical to the adjustments provided in Section 8. The above provision of this
subsection shall similarly apply to successive consolidations, mergers, sales or
conveyances.

                  Section 8.6 No Adjustment of Exercise Price in Certain Cases.
No adjustment of the Exercise Price shall be made:

                           (a) Upon the issuance or sale of the Warrants or the
                  Warrant Securities issuable upon the exercise of the Warrants;

                           (b) If the amount of said adjustment shall be less
                  than ten cents (10(cent)) per Warrant Security, provided,
                  however, that in such case any adjustment that would otherwise
                  be required then to be made shall be carried forward and shall
                  be made at the time of and together with the next subsequent
                  adjustment which, together with any adjustment so carried
                  forward, shall amount to at least ten cents (10(cent)) per
                  Warrant Security. Section 8.7 Form of Warrant After 
                  Adjustments.

                  Section 8.7 Form of Warrant. The form of the Warrant
Certificates need not be changed because of any adjustments in the Exercise
Price or number of Warrant Securities, and warrant certificates theretofore or
thereafter issued may continue to express the same Exercise Price and number of
Warrant Securities as are stated in the respective Warrant Certificates, as
initially issued.

                  9. Exchange and Replacement of Warrant Certificates. Each
Warrant Certificate is exchangeable without expense, upon the surrender thereof
by the registered Holder at the principal executive office of the Company, for a
new Warrant Certificate of like


 
                                     - 24 -

<PAGE>



tenor and date representing in the aggregate the right to purchase the same
number of Warrant Securities in such denominations as shall be designated by the
Holder thereof at the time of such surrender. The Company may require such
Holder to pay only those expenses which represent a sum sufficient to cover any
tax or governmental charge that may be imposed in connection with any such
exchange.

                  Upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and reimbursement to the Company of all
reasonable expenses incidental thereto, and upon surrender and cancellation of
the Warrants, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

                  10. Elimination of Fractional Interests. The Company shall not
be required to issue certificates representing fractions of shares of
Convertible Preferred Stock, shares of Common Stock or Redeemable Warrants upon
the exercise of the Warrants, nor shall it be required to issue scrip or pay
cash in lieu of fractional interests, it being the intent of the parties that
all fractional interests shall be eliminated by rounding any fraction up to the
nearest whole number of shares of Convertible Preferred Stock, shares of Common
Stock or Redeemable Warrants or other securities, properties or rights.

                  11. Reservation and Listing of Securities. The Company shall
at all times reserve and keep available out of its authorized shares of
Convertible Preferred Stock and Common Stock, solely for the purpose of issuance
upon the exercise of the Warrants and the Redeemable Warrants, such number of
shares of Convertible Preferred Stock and Common


 
                                     - 25 -

<PAGE>



Stock or other securities, properties or rights as shall be issuable upon the
exercise, conversion or redemption thereof. The Company covenants and agrees
that, upon exercise of the Warrants and payment of the Exercise Price therefor,
all shares of Convertible Preferred Stock, shares of Common Stock, Redeemable
Warrants and other securities issuable upon such exercise shall be duly and
validly issued, fully paid, non-assessable and not subject to the preemptive
rights of any stockholder. The Company further covenants and agrees that upon
exercise of the Redeemable Warrants underlying the Warrants and/or redemption or
conversion of the Preferred Shares, and payment of the respective Exercise Price
therefor, all shares of Common Stock and other securities issuable upon such
exercise, redemption or conversion, as the case may be, shall be duly and
validly issued, fully paid, non-assessable and not subject to the preemptive
rights of any stockholder. As long as the Warrants shall be outstanding, the
Company shall use its best efforts to cause all shares of Convertible Preferred
Stock and Common Stock issuable upon the exercise of the Warrants and Redeemable
Warrants, all shares of Common Stock issuable upon conversion or redemption of
the Preferred Shares and all Redeemable Warrants underlying the Warrants to be
listed (subject to official notice of issuance) on all securities exchanges on
which the Convertible Preferred Stock, Common Stock and/or the Public Warrants
issued to the public in connection herewith may then be listed and/or quoted on
Nasdaq.

                  12. Notices to Warrant Holders. Nothing contained in this
Agreement shall be construed as conferring upon the Holders the right to vote or
to consent or to receive notice as a stockholder in respect of any meetings of
stockholders for the election of directors or any other matter, or as having any
rights whatsoever as a stockholder of the Company. If,


 
                                     - 26 -

<PAGE>



however, at any time prior to the expiration of the Warrants and their exercise,
any of the following events shall occur:

                           (a) the Company shall take a record of the holders of
                  its shares of Common Stock for the purpose of entitling them
                  to receive a dividend or distribution payable otherwise than
                  in cash, or a cash dividend or distribution payable otherwise
                  than out of current or retained earnings or capital surplus
                  (in accordance with applicable law), as indicated by the
                  accounting treatment of such dividend or distribution on the
                  books of the Company; or

                           (b) the Company shall offer to all the holders of its
                  Common Stock any additional shares of capital stock of the
                  Company or securities convertible into or exchangeable for
                  shares of capital stock of the Company, or any option, right
                  or warrant to subscribe therefor; or

                           (c) a dissolution, liquidation or winding up of the
                  Company (other than in connection with a consolidation or
                  merger) or a sale of all or substantially all of its property,
                  assets and business as an entirety shall be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least thirty (30) days prior to the date fixed as a record date
or the date of closing the transfer books for the determination of the
stockholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, or entitled to vote on such
proposed dissolution, liquidation, winding up or sale. Such notice shall specify
such record date or the date of closing the transfer books, as the case may be.
Failure to give such notice


 
                                     - 27 -

<PAGE>



or any defect therein shall not affect the validity of any action taken in
connection with the declaration or payment of any such dividend, or the issuance
of any convertible or exchangeable securities, or subscription rights, options
or warrants, or any proposed dissolution, liquidation, winding up or sale.

                  13. Redeemable Warrants.

                  The form of the certificate representing Redeemable Warrants
(and the form of election to purchase shares of Common Stock upon the exercise
of Redeemable Warrants and the form of assignment printed on the reverse
thereof) shall be substantially as set forth in Exhibit "A" to the Warrant
Agreement dated as of the date hereof by and among the Company, the
Representative and The Bank of New York (the "Redeemable Warrant Agreement").
Each Redeemable Warrant issuable upon exercise of the Warrants shall evidence
the right to initially purchase a fully paid and non-assessable share of Common
Stock at an initial purchase price of $______ [140% of the initial public
offering price per share] from ______ 1998 [one year from the effective date of
the Registration Statement] until 5:30 p.m. New York time on _________ 2002 [5
years from the effective date of the Registration Statement] at which time the
Redeemable Warrants, unless the exercise period has been extended, shall expire.
The exercise price of the Redeemable Warrants and the number of shares of Common
Stock issuable upon the exercise of the Redeemable Warrants are subject to
adjustment, whether or not the Warrants have been exercised and the Redeemable
Warrants have been issued, in the manner and upon the occurrence of the events
set forth in Section 8 of the Redeemable Warrant Agreement, which is hereby
incorporated herein by reference and made a part hereof as if set forth in its
entirety herein. Subject to the provisions of this Agreement and upon issuance
of


 
                                     - 28 -

<PAGE>



the Redeemable Warrants underlying the Warrants, each registered holder of such
Redeemable Warrant shall have the right to purchase from the Company (and the
Company shall issue to such registered holders) up to the number of fully paid
and non-assessable shares of Common Stock (subject to adjustment as provided
herein and in the Redeemable Warrant Agreement), free and clear of all
preemptive rights of stockholders, provided that such registered holder complies
with the terms governing exercise of the Redeemable Warrant set forth in the
Redeemable Warrant Agreement, and pays the applicable exercise price, determined
in accordance with the terms of the Redeemable Warrant Agreement. Upon exercise
of the Redeemable Warrants, the Company shall forthwith issue to the registered
holder of any such Redeemable Warrant in his name or in such name as may be
directed by him, certificates for the number of shares of Common Stock so
purchased. Except as otherwise provided in this Agreement, the Redeemable
Warrants underlying the Warrants shall be governed in all respects by the terms
of the Redeemable Warrant Agreement. The Redeemable Warrants shall be
transferable in the manner provided in the Redeemable Warrant Agreement, and
upon any such transfer, a new Redeemable Warrant Certificate shall be issued
promptly to the transferee. The Company covenants to, and agrees with, the
Holder(s) that without the prior written consent of the Holder(s), which will
not be unreasonably withheld, the Redeemable Warrant Agreement will not be
modified, amended, canceled, altered or superseded, and that the Company will
send to each Holder, irrespective of whether or not the Warrants have been
exercised, any and all notices required by the Redeemable Warrant Agreement to
be sent to holders of Redeemable Warrants.

                                                           _____________, 1997

Commodore Environmental Services, Inc.
150 East 58th Street, Suite 3400
New York, New York  10158

Gentlemen:

         This letter agreement sets forth the terms and conditions under which
Commodore Separation Technologies, Inc., a Delaware corporation ("CST"), agrees
to provide a $_____________ credit commitment to Commodore Environmental
Services, Inc., a Delaware corporation ("COES").

         1. Credit Commitment.

            (a) Subject to the terms and conditions hereof and of the Non-
Negotiable Promissory Note, of even date herewith, made by COES in favor of CST,
a copy of which is attached hereto (the "Note"), CST agrees from time to time
during the two-year period commencing on the closing date of the initial public
offering of securities of CST, to make loans (each, a "Loan") to COES up to a
maximum aggregate amount of $_____________, which amount includes any accrued
and unpaid interest on amounts advanced and loaned by CST hereunder. COES shall
use the proceeds of each Loan for its working capital needs. Interest on the
outstanding principal amount of the Note shall be twelve percent (12%) per
annum, as more fully set forth in the Note. Subject to Section 2 below, the
maximum credit commitment may be reduced under certain circumstances. COES's
obligations under the Note shall be secured by a lien and pledge in the
Collateral, as more fully set forth in the Pledge Agreement.

            (b) By written request to CST, accompanied by a description of the
proposed use(s) of such loan proceeds, COES may from time to time request that
CST make a Loan in the amount specified therein and CST will make such Loan.
Subject to CST's review and approval of the written request, CST may, in its
discretion, disburse the amount of the Loan requested by wire transfer in
immediately available funds to an account or accounts designated in writing by
COES, or by check if mutually agreed, within three (3) business days following
COES's written request. Each such request for a Loan shall constitute COES's
representation and warranty to CST that no Event of Default (as such term is
defined in the Note) shall have occurred or be continuing at such time, or would
occur after giving effect to any such Loan.




<PAGE>



            (c) Except as otherwise provided in Section 2 below, COES will pay
the entire principal balance then outstanding of the Note together with accrued
interest, in cash, on the second annual anniversary of the date hereof.

         2. Mandatory Payments.

            (a) During the term of the Note, COES will pay, in whole or in part,
the principal balance then outstanding of the Note, together with accrued
interest, with the cash proceeds in excess of $______________, from the issuance
of any note, bond, debenture, evidence of indebtedness, share of capital stock
or any other security ("securities"), other than secured financing of assets in
the ordinary course of business, issued by COES after the date hereof (a
"Financing"). The obligation of COES to pay the outstanding balance under the
Note pursuant to the preceding sentence shall be superior and first in priority
to any other use of the proceeds of a Financing, and COES agrees not to enter
into any agreement or instrument during the term of the Note which would modify
or alter the foregoing priority.

            (b) In the event no amounts are outstanding under the Note at the
time of a Financing, the maximum credit commitment set forth in Section 1(a)
above will be reduced by the amount of the cash proceeds of any such Financing.

         3. Change in Control. A Change in Control (as defined below) during the
term of the Note shall be considered an Event of Default, in which case COES
shall be required, unless waived by CST in whole or in part, to pay the entire
principal balance then outstanding of the Note, together with accrued interest,
on or within ten (10) days following the Change in Control. A "Change in
Control" shall be deemed to have occurred when (a) a third person, including a
"group," as such term is defined in Section 13(d)(3) of the Securities Exchange
Act of 1934, other than CST or its affiliates, becomes (other than as a result
of a purchase from COES) the beneficial owner of shares of COES having 10% or
more of the total number of votes that may be cast for the election of directors
of COES and such beneficial owner continues for five consecutive days, or (b) as
a result of, or in connection with, any cash tender or exchange offer, merger or
other business combination, sale of assets or contested election or any
combination of the foregoing transactions, the persons who were directors of
COES before such transaction shall cease for any reason to constitute at least a
majority of the Board of Directors of COES or any successor.

         4. Representations. Each of the parties hereto represents severally and
as to itself only that this letter agreement has been duly authorized, executed
and delivered by it and, assuming the due authorization, execution and delivery
of this letter agreement by the other party hereto, constitutes its legal, valid
and binding obligation, enforceable against it in accordance with its terms,
except to the extent that enforceability (x) may be limited by bankruptcy,
insolvency or other similar laws affecting or relating to the enforcement of
creditors' rights generally and (y) is subject to general principles of equity
(whether such enforceability is considered in a proceeding in equity or at law).

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



                                                      Dated:  ______________



         FOR VALUE RECEIVED, the undersigned, COMMODORE ENVIRONMENTAL SERVICES,
INC., a Delaware corporation ("Borrower"), promises to pay to COMMODORE
SEPARATION TECHNOLOGIES, INC., a Delaware corporation ("CST"), at the principal
executive offices of CST, 150 East 58th Street, Suite 3400, New York, New York
10158, or at such commercial bank within the United States of America as CST may
designate to Borrower from time to time, in lawful money of the United States of
America and in immediately available funds, the outstanding amount of all loans
made by CST to Borrower from time to time in accordance with the provisions
hereof. Borrower further agrees to pay interest in like money at such office or
commercial bank on the unpaid aggregate principal amount hereof at a rate equal
to twelve percent (12%) per annum.

         1. Payment of this Note is secured by certain collateral (the
"Collateral") under the terms of the Pledge Agreement, of even date herewith,
between Borrower and CST.

         2. Principal and interest shall be due and payable in the manner set
forth below:

            (a) Accrued interest on the unpaid principal amount hereof shall be
        paid quarterly in cash.

            (b) Borrower will pay, in whole or in part, the principal balance
        then outstanding of this Note, together with accrued interest, on or
        within five (5) days after each date Borrower receives cash proceeds in
        excess of $___________ from a Financing, as such term is defined in the
        letter agreement, of even date herewith, between Borrower and CST (the
        "Letter Agreement").

            (c) Borrower will pay the entire principal balance then outstanding
        of this Note, together with accrued interest, in cash, on the second
        annual anniversary of the date hereof.

            (d) All payments (including prepayments) made hereunder shall be
        applied first to the payment of accrued and unpaid interest, with the
        balance remaining applied to the payment of the unpaid principal balance
        of this Note.

            (e) This Note may, at the option of Borrower, be prepaid at any time
        in whole or in part, without premium or penalty.

         3. Borrower is borrowing the principal sum of this Note pursuant to the

supersede the terms of this Note in the event of any conflict. This Note shall
be non-negotiable.




<PAGE>



         4. CST is authorized to record the date and amount of each loan made by
it and the date and amount of each payment, prepayment or reduction of the
principal amount hereof on the schedule annexed hereto and made a part hereof,
and any such recordation shall constitute prima facie evidence of the accuracy
of the information so recorded.

         5. Notwithstanding any provision to the contrary contained in this
Note, it is expressly agreed that the entire principal amount outstanding at any
time under this Note, and all accrued and unpaid interest, shall immediately
become due and payable (without demand for payment, notice of non-payment,
presentment, notice of dishonor, protest, notice of protest or any other notice,
all of which are hereby expressly waived by Borrower):

            (a) upon the default in the payment of any interest or principal due
        under this Note, which default continues uncured for a period of ten
        (10) days;

            (b) if Borrower shall make an assignment for the benefit of
        creditors; or shall admit in writing its inability to pay its debts; or
        if a receiver or trustee shall be appointed for Borrower or for
        substantially all of its assets and, if appointed without its consent,
        such appointment is not discharged or stayed within thirty (30) days; or
        if proceedings under any law relating to bankruptcy, insolvency or the
        reorganization or relief of debtors are instituted by or against the
        Borrower and, if contested by it, are not dismissed or stayed within
        thirty (30) days; or if any writ of attachment or execution or any
        similar process is issued or levied against Borrower or any significant
        part of its property and is not released, stayed, bonded or vacated
        within thirty (30) days after its issue or levy; or if Borrower takes
        corporate action in furtherance of any of the foregoing;

            (c) after a Change in Control, as provided, and as such term is
        defined, in the Letter Agreement (each, an "Event of Default"); or

            (d) any event of default which results in the acceleration of
        indebtedness of Borrower to any other person under any note, indenture,
        agreement or undertaking and that is not cured within thirty (30) days.

         6. All notices, requests and demands to or upon Borrower or CST to be
effective shall be in writing and shall be deemed to have been duly given or
made when delivered by hand, or when sent by certified mail, postage prepaid,
addressed as follows or to such other address as may hereafter be notified by

         7. No failure or delay on the part of CST in exercising any of its
rights, powers or privileges hereunder shall operate as a waiver thereof, nor

exercise of any right, power or privilege. Borrower hereby waives demand for
payment, notice of non-payment, presentment, notice of dishonor, protest, notice
of protest or any other notice in connection with the delivery, acceptance,
performance or enforcement of this Note.

fees.

         9. This Note shall be governed by and construed in accordance with the
