(the "Company") was incorporated in February 1988 under the name "Thorne Environmental, Inc." to conduct business in environmental consulting, engineering, remediation and construction. The Company's initial growth resulted from its successful performance of emergency response cleanup services in certain western states and the Trust Territory of the Pacific Islands for the U.S. Government. The Company has since developed a broad range of expertise in non-proprietary technology-based environmental remediation and water treatment techniques for both the public and private sectors throughout North and South America and the Trust Territory of the Pacific Islands. The Company was purchased by its existing majority shareholders in November 1991, and for the last five years has engaged in a program of expansion through internal client development and add-on contracts, the acquisition of personnel and assets in desirable geographic locations, and the acquisition of smaller companies involved with target growth technologies. The Company has built a large backlog of government work through the award of several multi-year contracts primarily with the Environmental Protection Agency and the Department of Defense. The Company has achieved and maintains a balance between its commercial and government sector business through an aggressive industrial marketing strategy. To date, the Company has performed remediation services for both public and private sector customers at more than 500 sites. The Company's strategy has been to distinguish itself in the market by providing full service environmental contracting, municipal and industrial water and wastewater treatment, and emergency response services. Through several major government contracts and a diversified commercial client base, the Company provides turnkey waste management for a complete range of water, soil and air pollution issues. The Company's personnel have developed expertise in a broad range of remediation techniques such as bioremediation, bioventing, vapor extraction, gas/air sparging, thermal desorption, soil washing and groundwater remediation systems. The Company also offers a broad range of services in support of municipal and industrial water and wastewater treatment, military base closures, and other operations with significant environmental components. The Company believes it has gained a solid reputation for promptly providing cost effective and innovative remediation solutions. In November 1996, the Company relocated its corporate headquarters to Englewood, Colorado from Tustin, California to be more centrally located for its expanding business. The Company also maintains offices in Tustin, California; Richmond, California; Portland, Oregon; Edmonds, Washington; Phoenix, Arizona; Pasadena, Texas; New Orleans, Louisiana; Jackson, Mississippi; and Mobile, Alabama. The Company's headquarters are located at 7670 South Vaughn Court, Suite 130, Englewood, Colorado 80112, and its telephone number is (303) 708-1360. The Company's fax number is (303) 708-1349 and its internet address is http://www.cetenvironmental.com. -4- RISK FACTORS An investment in the securities being offered by this Prospectus involves a high degree of risk. In addition to the other information contained in this Prospectus or incorporated herein by reference, prospective investors should carefully consider the risk factors discussed below before purchasing the shares of Common Stock offered hereby. This Prospectus contains and incorporates by reference forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Such statements are based on management's current expectations and are subject to a number of factors and uncertainties which could cause actual results to differ materially from those described in the forward-looking statements. Reference is made in particular to the description of the Company's plans and objectives for future operations, assumptions underlying such plans and objectives and other forward-looking statements included or incorporated in this Prospectus. Factors which could cause such results to differ materially from those described in the forward-looking statements include those set forth in the risk factors below. 1. COSTS OF COMPLIANCE WITH, AND POTENTIAL LIABILITY UNDER, ENVIRONMENTAL LAWS AND REGULATIONS. Due to the nature of the Company's business and the intense regulatory climate in which it operates, the services of the Company are subject to extensive federal, state and local laws and regulations which are constantly changing. Such regulations impose stringent guidelines on companies which handle hazardous materials as well as other companies involved in various aspects of the environmental remediation services industry. Failure to comply with applicable federal, state and local regulations could result in substantial costs to the Company, the imposition of penalties or in claims not covered by insurance, any of which could have a material adverse effect on the Company's business. In addition to the burdens imposed on Company operations by various environmental regulations, federal law imposes strict joint and several liability upon present and former owners and operators of facilities that release hazardous substances into the environment and the generators and transporters of such substances as well as persons arranging for the disposal of such substances. All such persons may be liable for the costs of waste site investigation, waste site clean up, natural resource damages and related penalties and fines. Such costs can be very substantial. Environmental remediation operations may expose the Company's employees and others to dangerous and potentially toxic quantities of petroleum or other hazardous products. Such products can cause cancer and other debilitating diseases. Although the Company takes extensive precautions to minimize worker exposure and has not experienced any such claims from workers or others, there can be no assurance that the Company will avoid liability to persons who contract diseases which may be related to such exposure. Such persons potentially include the Company's employees, persons occupying or visiting facilities in which contaminants are being, or have been, removed or stored, persons in surrounding areas, and persons engaged in the transportation and disposal of waste material. In addition, the Company is subject to general risks inherent in the construction industry. The Company may also be exposed to liability from the acts of its subcontractors or other contractors on a work site. Currently, the Company has $5,000,000 per occurrence and $5,000,000 aggregate comprehensive general liability insurance coverage. In addition, the Company carries environmental impairment liability insurance in the amount of -5- 2,000,000 per occurrence with a $2,000,000 aggregate. Errors and omissions liability insurance for petroleum and chemical exposure for claims made in the coverage period is also provided. While the Company has never been subject to a claim relating to petroleum/chemical exposure and believes that its current coverage is adequate, there can be no assurance that the Company will be able to maintain its existing coverage, that claims will not exceed the amount of insurance coverage or that there will not be claims relating to prior periods that were not covered by insurance, any of which could have a material adverse effect upon the Company. Because of the nature of the Company's operations and the industry in which it operates, the potential for liability and the extent of such potential liability is very substantial. Any such liability could have a material adverse impact on the Company's business and financial condition. 2. DEPENDENCE ON CONTINUED ENVIRONMENTAL REGULATION. The growth of the environmental remediation services industry, as well as the growth of the Company, has been largely attributable to, and tracks the increase in, environmental regulation since the 1970s and the response of governmental and commercial entities and financial institutions to public concern with environmentally contaminated facilities. The demand for environmental remediation services has been largely the result of facility and property owners attempting to comply with, or avoid liability under, existing or newly imposed environmental regulations at the federal, state and local levels. Because of the burden imposed on industry in complying with such regulations, efforts have been made by various groups to seek the relaxation or repeal of certain forms of environmental regulation. While such efforts have been largely unsuccessful to date, there can be no assurance that the scope or growth of such regulation will not be curtailed in the future. Any relaxation of environmental regulation may result in a decline in demand for environmental remediation services and may adversely affect the operations of the Company. For example, the Resource Conservation and Recovery Act ("RCRA") mandates that by December 31, 1998, every single walled underground storage tank ("UST") in the United States must be removed and replaced with a double walled tank, and that any environmental damage to the soil or water caused by tank leakage must be remediated. As a result, the Company's business in UST removals and installations will likely be reduced after that date. Management doesn't expect that this reduction after December 31, 1998, will have a material adverse effect on the Company because this line of business represents less than ten percent of the Company's business at the present time. 3. DEPENDENCE ON MAJOR CUSTOMER. The Company is dependent upon its relationship and contract with the EPA which accounted for approximately 20% and approximately 27% of the Company's revenues in 1996 and 1995, respectively. While the Company continues to increase the amount of work performed for entities other than the EPA and thereby reduce its dependence on the EPA, the Company will continue to be significantly dependent on EPA contracts for the foreseeable future. 4. DEPENDENCE ON SPENDING LEVELS OF GOVERNMENTAL AND INDUSTRIAL ENTITIES. Because of the nature of sites requiring environmental remediation services, the growing public emphasis on environmental matters and the cost of environmental remediation services, a significant portion of all funds spent for such services has been spent by governmental agencies and large industrial concerns. While third party reimbursement may be sought in various cleanups, most Superfund cleanups as well as weapons and other nuclear facility cleanups involve significant spending by governmental agencies. As budget constraints and emphasis on employment, international competition and other considerations grow, certain governmental agencies and industrial concerns may choose to delay or curtail expenditures for environmental remediation services. Any curtailment or delays -6- in spending for environmental remediation services by governmental agencies or large industrial concerns can be expected to have a material adverse effect on the environmental remediation services industry generally, and on the operations and financial results of the Company. 5. MANAGEMENT OF GROWTH. The Company has experienced a period of rapid growth in its operations. This growth has resulted in an increase in the level of responsibility for members of the Company's management team. Few of these managers have had experience managing businesses which have experienced a rate of growth similar to that of the Company. The Company's ability to manage growth successfully will require it to continue to improve its operational, management and financial systems and controls and to expand, train, manage and retain its employee base. Failure of the Company's management to do so could have a material adverse effect on the Company's business, operating results and financial condition. 6. BUSINESS SUBJECT TO WEATHER CONDITIONS. While the Company provides its services on a year round basis, the Company's services provided outdoors or outside of a sealed environment may be adversely affected by inclement weather conditions. Extended periods of rain, cold weather or other inclement weather conditions may result in delays in commencing or completing projects, in whole or in part. Any such delays may adversely affect the Company's operations and financial results and may adversely affect the performance of other projects due to scheduling and staffing conflicts. 7. DEPENDENCE ON ABILITY TO SECURE BONDING. In order to successfully bid on and secure contracts to perform environmental remediation services of the nature offered by the Company, the Company oftentimes must provide surety bonds with respect to each respective project. Thus the number and size of contracts which the Company can perform is directly dependent upon the Company's ability to obtain bonding which, in turn, is dependent upon the Company's net worth and liquid working capital. There can be no assurance that the Company will have adequate bonding capacity to bid on all of the projects which it would otherwise bid upon were it to have such bonding capacity or that it will in fact be successful in obtaining additional contracts on which it may bid. 8. FIXED PRICE AND PER UNIT CONTRACTS. Historically, less than 5% of the Company's remediation contracts are on a fixed price or per unit basis. Cost overruns on projects covered by such contracts due to such things as unanticipated price increases, unanticipated problems, inefficient project management, inaccurate estimation of labor or material costs or disputes over the terms and specifications of contract performance could have a material adverse effect on the Company and its operations. There can be no assurance that cost overruns will not occur in the future and have a material adverse effect on the Company. In addition, in order to remain competitive in the future, the Company may have to agree to enter into more fixed price and per unit contracts than in the past. 9. LACK OF SIGNIFICANT OPERATING HISTORY. The Company has been in existence since 1988 and was acquired by current management in November 1991. As such, the Company is subject to many of the risks common to enterprises with a limited operating history, including potential under capitalization, limitations with respect to personnel, financial and other resources and limited customers and revenues. There is no assurance that the Company's activities will be successful and the likelihood of success must be considered in light of its current stage of development. -7- 10. FUTURE CAPITAL NEEDS AND UNCERTAINTY OF ADDITIONAL FINANCING. The Company's long term capital requirements will depend on many factors, including, but not limited to, cash flow from operations, the level of capital expenditures, working capital requirements and the growth in its business. Historically, the Company has relied upon commercial borrowings, a public offering, borrowings from shareholders and affiliates of shareholders and retained earnings to fund its operations and capital needs. The Company has established a line of credit with a commercial bank which provides up to $9 million in credit depending on the amount of eligible accounts receivable and contracts in progress. As of September 30, 1997, there was $4,594,078 outstanding under this line of credit. The Company may need to incur additional indebtedness to fund the capital needs related to its growth. To the extent additional debt financing cannot be raised on acceptable terms, the Company may need to raise additional funds through public or private equity financings. No assurance can be given that additional equity financing will be available or that, if available, the terms of such financing will be favorable to the Company or to its shareholders without substantial dilution of their ownership and rights. If adequate funds are not available, the Company may be required to curtail its future operations significantly or to forego market or expansion opportunities. 11. COMPETITION. Competition in the environmental remediation services industry is intense, and the success of the Company is dependent upon its ability to secure contracts. Government, state and local contracts are awarded based upon competitive bidding, and the Company is not always the lowest bidder. The Company's future success will be dependent upon the Company's ability to competitively bid contracts and to perform them on a profitable basis. In addition, the Company will need to grow in order to remain competitive with larger competitors. The industry is dominated by a few large engineering construction firms. Such firms are called upon to serve as primary contractors and consultants on a large portion of the federal and state government projects. Additionally, many smaller engineering firms, construction firms, consulting firms and other specialty firms have entered the environmental remediation services industry in recent years and additional firms can be expected to enter into the industry in the future. Many of the firms with which the Company competes in the environmental remediation services industry have significantly greater financial resources and more established market positions than the Company. While management believes that the Company's experience and expertise in the broad range of services which it offers allows the Company to compete successfully, there can be no assurance that this will continue or that other firms will not expand into or develop expertise in the areas in which the Company specializes, thus increasing competition to the Company. 12. CONCENTRATION OF CREDIT RISK. The Company contracts with a limited number of customers which are involved in a wide range of industries. A small number of customers may therefore be responsible for a majority of revenues at any time. While management assesses the credit risk associated with each proposed customer prior to the execution of a definitive contract, no assurances can be given that such assessments will be correct and that the Company will not sustain substantial, noncollectible accounts receivable. 13. DEPENDENCE ON EXECUTIVE MANAGEMENT AND OTHER QUALIFIED PERSONNEL. The operations of the Company are substantially dependent on its executive officers who are also its principal shareholders and directors. The Company has no employment contracts with these persons. The loss of their services could have a material adverse effect on the Company. The Company's further success will also depend significantly on its ability to attract and retain additional skilled -8- personnel, including highly trained technical personnel, project managers and supervisors. The Company believes it currently has adequate qualified supervisory personnel, but there is no assurance that experienced and qualified management level personnel will be available to the Company in the future to fill positions as needed. 14. CONTROL BY OFFICERS, DIRECTORS AND MAJOR SHAREHOLDERS. Officers and directors of the Company, specifically Messrs. Craig C. Barto, Steven H. Davis, John G. L. Hopkins and Douglas W. Cotton, beneficially own an aggregate of approximately 57.0% percent of the issued and outstanding shares of the Company's Common Stock. Under California law, shareholders of the Company have cumulative voting rights; however, it is likely that despite such rights, present management will continue to be able to control the Board of Directors of the Company. 15. DIVIDENDS. The Company does not anticipate paying any cash dividends for the foreseeable future. The Company expects that future earnings, if any, will be used to finance growth. No person seeking dividend income from an investment should invest in this offering. 16. SHARES ELIGIBLE FOR FUTURE SALE. Of the 5,804,585 shares of the Company's Common Stock issued and outstanding as of December 22, 1997, approximately 4,013,248 are "restricted securities" as that term is defined under Rule 144 promulgated under the 1933 Act. Of these shares, 729,248 are being offered for resale by the Selling Shareholders listed in this Prospectus. Craig C. Barto, Douglas W. Cotton, Steven H. Davis, and John G. L. Hopkins, Officers and Directors of the Company, have agreed that, without the prior written consent of the selling agent in the Company's December 1996 private offering, they and their affiliates will not sell any Common Stock until July 19, 1998, except that Mr. Hopkins will be allowed to sell a number of shares to be agreed upon by the selling agent. Such persons have also agreed that all of their Rule 144 sales during the two year period ending December 9, 1998, will be executed through the selling agent acting as a broker or dealer. Sales of shares of the Company's Common Stock which might be registered or sales made pursuant to Rule 144 or otherwise could adversely affect the market price of the Company's Common Stock and make it more difficult for the Company to sell equity securities in the future at a time and price which it deems appropriate. The Company is unable to predict the effect that sales made under registration statements or Rule 144 or otherwise may have on the then prevailing market price of the Common Stock. Nonetheless, the possibility exists that the sale of these shares may depress the price of the Company's Common Stock. -9- RECENT EVENTS At its Annual Meeting of Shareholders held on May 15, 1997, Rick C. Townsend, who has been Executive Vice President and Chief Financial Officer of the Company since November 1996, was elected as an additional Director of the Company. The six other Directors of the Company were also re-elected at that meeting. Effective January 1, 1998, Mr. Townsend will become Secretary of the Company. In July 1997, the Company announced that it had received a delivery order to construct a groundwater extraction, treatment and discharge system at the Cornhusker Army Ammunition Plant near Grand Island, Nebraska. This project is valued at $9 million and involves the remediation of a subsurface explosives contaminant plume. The work is scheduled to last approximately 18 months. This project has been issued under the Company's $25 million U.S. Army Corps of Engineers Preplaced Remedial Action Contract ("PRAC"). In August 1997, the Company acquired Water Quality Management Corporation ("WQM"), a privately held company headquartered in Golden, Colorado. WQM specializes in the contract operations of industrial and municipal water and wastewater treatment facilities. WQM has 17 current water/wastewater treatment contracts including sanitation districts such as Black Hawk/Central City, Perry Park, Town of Larkspur, Stonegate Metropolitan District, and Cherry Creek Village Metro District. With this acquisition, the Company now has approximately 50 water and wastewater treatment facility operation and maintenance contracts in Colorado. This acquisition did not have a material impact on the revenue or net profit of the Company. In August 1997, the Company also announced that it had been awarded contracts totaling $1 million for water and wastewater facilities in Idaho Springs, Silverthorne, and Parshall, Colorado, and a $1.55 million groundwater treatment project for a Department of Energy site in Wyoming. The first project with the Colorado Department of Public Health and Environment is for the start-up, operation and maintenance of the Argo Tunnel Water Treatment Facility in Idaho Springs. The $500,000 project is for the first year of operation and is renewable for up to four additional years. The project is funded jointly by the State of Colorado and the U.S. Environmental Protection Agency and is part of the Clear Creek/Central City Superfund site. The facility will treat acid mine drainage from the Argo Tunnel, which has historically been a pollution source into Clear Creek. The second contract is to prepare a preliminary plan to design, build and operate, and provide financing options for, water supply improvements for the Hamilton Creek Metropolitan District near Silverthorne. The project includes the development of a new deep aquifer water supply well, distribution lines, booster pumps, and improved treatment. The project is scheduled for preliminary planning in August 1997, and construction is to begin as early as the spring of 1998. The third contract was awarded by Climax Molybdenum Company, a subsidiary of Cyprus Amax, to design, build and operate a microfiltration water treatment plant at their Henderson Mill facility near Parshall, Colorado. The plant will be a replacement system designed to treat high turbidity surface water from a mountain water source to meet the potable water requirements set forth by the State of Colorado for the molybdenum processing plant. The Company was also issued a delivery order to construct a groundwater remediation system at the Hoe Creek Department of Energy site near Gillette, Wyoming. This project is valued at $1.55 million and involves the air sparging -10- treatment of two aquifers impacted with benzene and phenols. The work has been started and will last approximately 18 months. This project has been issued under the Company's $25 million U.S. Army Corps of Engineers Preplaced Remedial Action Contract ("PRAC"). On August 25, 1997, the Company received notice that the Air Force Center for Environmental Excellence ("AFCEE") selected the Company as one of three firms eligible to receive work under the $75 million small-business set- aside program. The Company is also a team member with Montgomery/Watson, Pasadena, California, which was selected as one of four firms eligible to receive work under the AFCEE large-business contracts worth a combined value of $400 million. The Company will perform approximately 15 percent of Montgomery/Watson's work. There is no assurance as to how much work, if any, the Company will receive under these two programs. In August, 1997, the Company was awarded a contract to design, build and operate for one year a wastewater treatment facility for Monfort, Inc. at Monfort's beef packing plant in Garden City, Kansas. The contract is valued at approximately $6.8 million. In August, 1997, the Company was awarded a $2.6 million contract by a unit of Coastal Corporation to perform soil and groundwater remediation services at a refinery in San Pedro, California. The project includes the design, construction and operation of a soil vapor extraction and air sparging system. In September 1997, the Company announced that it had been awarded an Emergency and Rapid Response Services ("ERRS") contract by the U.S. Environmental Protection Agency ("EPA") Region 10. This region includes the states of Washington, Oregon, Idaho, and Alaska. This five-year contract has a potential value of $40 million and will involve the cleanup of contaminants and hazardous materials on an emergency and planned basis.

ITEM 16. EXHIBITS. Exhibit Number Description - ------- ----------- 5 Opinion of Krys Boyle Freedman & Sawyer, P.C., with respect to the legality of the securities being registered 23.1 Consent of Grant Thornton LLP 23.2 Consent of Krys Boyle Freedman & Sawyer, P.C. (contained in Exhibit 5) ITEM 17. UNDERTAKINGS. The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10 (a) (3) of the 1933 Act; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the II-1 Commission pursuant to Rule 424(b) ([Section] 230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; Provided, however, that paragraphs (l)(I) and (l)(ii) do not apply if the registration statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the 1933 Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the 1933 Act, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the 1934 Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the 1934 Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue. II-2 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement on Form S-3 to be signed on its behalf by the undersigned, hereunto duly authorized, in Englewood, Colorado, on December 24, 1997.
