  Item 1.  Description of Business
  
  General
  
     Rentech, Inc. ("Rentech" or the "Company") was organized as a Colorado
  corporation in 1981 to develop and exploit processes for the conversion
  of natural gas and other low-value carbon-bearing gases and solids into
  valuable liquid hydrocarbons, including premium diesel fuel, naphthas and
  waxes.  The gas-to-liquids technology developed by the Company ("Rentech
  Process Technology" or "Technology") is protected by a series of patents
  issued by the U.S. Patent Office.  The ability of the Technology to
  convert carbon-bearing gases into valuable liquid hydrocarbons has been
  validated in two pilot plants operated periodically between 1982 and
  1989, in a 235 barrel per day commercial scale facility in 1992 and 1993,
  and in a third pilot plant presently being operated in Rentech's test
  facility at Pueblo, Colorado.  Rentech's gas-to-liquids Technology has
  been licensed for use in India in a 360 barrel per day plant that the
  licensee is now beginning to construct. 
  
       During March 1997, the Company entered into the business of
  manufacturing and selling water-based stains, sealers and coatings on a
  wholesale basis by purchasing the assets of Okon, Inc.  The Company is
  continuing the established business of Okon as a wholly-owned subsidiary
  under the name Okon, Inc. ("Okon").  Okon sells environmentally clean,
  water repellant sealers, coatings and stains for wood, concrete and
  masonry.  The customers are retailers who sell to the construction
  industry and architects.  Okon presently provides Rentech's primary
  source of revenues. 
  
       During July 1997, Rentech agreed with ITN Energy Systems, Inc., a
  privately-owned Colorado corporation, to enter into a new business called
  ITN Electronic Substrates LLC.  Rentech owns 50% of this new entity. The
  LLC will manufacture and sell several types of flexible thin-film on
  which it has electronically deposited metals with unique properties, such
  as copper and molybdenum, that provide conductive paths to which computer
  chips may be attached.  The new business intends to begin its first
  activities and begin production in 1998.  The customers are expected to
  be contract manufacturers in the computer, aerospace and medical
  instrument industries, as well as large end-users which use the flexible
  thin-film as substrates or base components for manufacturing their own
  products. 
  
       The Company's long-term plan is to diversify into three industry
  groups centered around its three present lines of business.  Rentech
  plans to continue licensing its gas-to-liquids Technology in a
  petrochemical group; to establish an environmental and industrial
  products group, in which Okon would be included; and to develop an
  advanced technology group which would include the new business of ITN
  Electronic Substrates LLC.

                                                        PAGE 3
  
       The Company is continuing its original business of licensing its
  gas-to-liquids Technology, including sale of its proprietary catalyst
  used in the conversion process.  Licences are granted in exchange for
  license fees and royalties on the production of liquid hydrocarbons from
  conversion plants that use the Technology and are constructed and owned
  by licensees.  Rentech  will provide its engineering design and technical
  services under contract to its licensees, for their use in constructing
  their plants, together with engineering services and startup operational
  support services on a fee basis for licensed plants.  In addition,
  Rentech may reserve the right to contract for the engineering and supply
  the synthesis gas conversion reactor modules that are essential to use of
  its Technology in conversion plants.  Rentech is not now receiving
  significant revenues from its gas-to-liquids Technology.  Rentech has
  licensed its Technology for use in a plant now under construction by its
  Indian licensee at Arunachal Pradesh, India.  
  
       On March 31, 1997, the Company entered into an agreement with Texaco
  Group, Inc. to negotiate with Texaco to establish a business relationship
  to accelerate the development and licensing of Rentech's Process
  Technology and to commercially exploit the Technology on a worldwide
  basis.  The negotiations are continuing on a positive basis.  There can
  be no assurance, however, that an agreement for a business relationship
  will be reached. 
  
  
  Gas-to-Liquids Technology --- Petrochemicals 
  
       Rentech was originally established to develop and exploit its
  Technology for the conversion of low-value carbon bearing solids or gases
  into valuable liquid hydrocarbons, including premium diesel fuel,
  naphthas and waxes.  The technical feasibility of the Company's
  Technology, that is, ability of the Company's conversion process to
  convert carbon-bearing gases into valuable liquid hydrocarbons was
  established in the Company's first pilot plant which operated
  periodically between 1982 and 1985, and again in its second pilot plant
  operated during 1989.  The Rentech Technology is based upon the
  Fischer-Tropsch conversion process that was originally developed in
  Germany during the 1930s to create synthetic fuels.  When petroleum
  imports became readily available after World War II, 
  Fischer-Tropsch research was abandoned.  The Arab oil embargo of 1973
  created fuel shortages, and that crisis renewed interest in
  Fischer-Tropsch processes.  Research was conducted at the Naval Weapons
  Center in China Lake, California and later at the Solar Energy Research
  Institute in Golden, Colorado.  Based in part on those efforts, Rentech
  developed its own gas-to-liquids conversion process as well as a catalyst
  that is essential to use of its Technology.
  
       Economic use of the Rentech gas-to-liquids Technology depends upon
  inexpensive sources of carbon-bearing gas or solids that can be
  efficiently converted into feedstock gases.  That normally will require
  location of conversion plants near the fuel sources. 
  
  
  
  
  
  
  
  
  
  
  
  
  <PAGE>
                                                        PAGE 4
    
       The Rentech Technology uses as feedstock natural gas from gas wells
  that are not producing or that flare gas, or synthesis gas, a mixture of
  hydrogen and carbon monoxide gases, produced by gasification of coal and
  other carbonaceous materials.  These sources of fuel are in abundant
  supply worldwide.  Other sources of feedstock include methane, a gas
  collected from coal beds, as well as industrial off gases.  The
  Technology can provide a means of utilizing gas resources that are
  currently unmarketable due to their remote locations or because of the
  presence of diluents such as carbon dioxide or nitrogen. 
  
       The principal products of the Rentech gas-to-liquids process are
  clean-burning and premium-grade diesel fuel, naphthas useful as a
  feedstock for chemical processing and for refining into varnishes and
  mineral spirits, and waxes useful in hot-melt adhesives, inks and
  coatings, and a variety of other wax-based products. 
  
       The Company's original business is licensing the Rentech
  gas-to-liquids Technology, including sale of its patented catalyst, in
  exchange for license fees and royalties on the production of liquid
  hydrocarbons from conversion plants that use the Technology and are
  constructed and owned by licensees.  Rentech also provides engineering
  design and technical services under contract with its licensees for their
  use in constructing their plants, and it provides engineering services
  and startup operational support services on a fee basis for licensed
  plants.  In addition, Rentech may reserve the right to contract for the
  engineering and supply of the synthesis gas conversion reactor modules
  that are essential to use of its Technology in conversion plants.  
  
       The Company has not in the past year and does not in the future
  intend to incur any costs for constructing plants that it would own,
  except that it may make investments to participate in minority ownership
  of future plants constructed by licensees.  See "Description of
  Business - Present Licenses and Contracts for the Gas-to-Liquids
  Conversion Technology."  
  
       Rentech is undertaking a study, with technical support from ITN
  Energy Systems, Inc., to evaluate use of the hydrogen produced as a
  byproduct of its gas-to-liquids Technology as a fuel source for operation
  of fuel cells.  Fuel cells produce electricity by reacting hydrogen and
  oxygen together electrochemically, rather than by combustion.  The result
  of the fuel cell process is electricity and water; there are no harmful
  emissions such as the carbon monoxide, oxides of nitrogen and other
  greenhouse gases produced by internal combustion engines.  Fuel cells
  cannot now be operated economically.  Because of the growing demand for
  pollution-free energy sources, significant efforts are being made by
  third parties to rapidly commercialize fuel cell technology for use in
  stationary power generators and in electric motor vehicles.  One of the
  major difficulties for the emerging field of fuel cell technology is a
  supply of hydrogen, which is normally expensive.  The hydrogen produced 
  
  
  
  
  
  
  
  
  
  
  
  
  
  <PAGE>
                                                        PAGE 5
  
  as a result of Rentech's gas-to-liquids Technology is already available
  at plants using that Technology.  If that hydrogen can be used in a
  stationary power fuel cell system associated with a petroleum refining
  unit that implements Rentech's gas-to-liquids Technology, the results
  could be both economically and environmentally beneficial. 
  
  
  Environmental and Industrial Products (Okon, Inc.)
  
       The Company in March 1997 entered into the business of manufacturing
  and selling water-based stains, sealers and coatings on a wholesale basis
  by purchasing the assets of Okon.  The coatings produced and sold by the
  Okon division are biodegradable and environmentally clean.  Its formulas
  used for manufacturing its products are proprietary.  The customers are
  primarily the construction industry and architects who use the coatings
  on wood, concrete and masonry.  Okon presently provides the Company's
  primary source of revenues. 
  
       Okon has been engaged for over 25 years in the business of
  manufacturing and marketing biodegradable and environmentally clean
  water-based wood stains, concrete stains, block pluggers and other water
  repellent sealers.  Okon markets and sells its products nationwide
  through a variety of channels.  These include distribution through paint
  dealers, industrial applications, retailers, excluding discount retailers
  and mass merchandisers, and architects and building contractors.  The
  Company has no direct sales force, distributors or independent sales
  representatives.  The brand names of the various products are recognized
  throughout the industry.  
  
       Okon manufactures and markets primarily standard products, but does
  prepare special products for large orders.  Sales are generally made
  pursuant to purchase orders, which are occasionally revised to reflect
  changes in the customer's requirements or to establish special orders. 
  Product deliveries are scheduled upon the Company's receipt of purchase
  orders, and orders are typically filled within one to two days.  The
  Company had no significant backlog of orders as of September 30, 1997. 
  Generally the purchase orders allow customers to reschedule delivery
  dates and cancel purchase orders without significant penalties.  Orders
  are occasionally rescheduled, revised or canceled.  For these reasons,
  the Company believes that its backlog, while useful for scheduling
  production, is not necessarily a reliable indicator of future revenues. 
  
       Historically, sales of coatings have been seasoned in nature.  The
  heaviest concentration of sales have occurred in the spring and summer
  months.  Production schedules are timed to reflect these seasonal
  variations. 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  <PAGE>
                                                        PAGE 6
    
       Okon's sales of products to certain customers, individually, may
  constitute a significant portion of its revenues.  One of these customers
  accounted for 34% of the total net sales for fiscal 1997.  As of
  September 30, 1997, two customers account for 40% of Okon's accounts
  receivable.  Okon, however, sells to over 2,000 customers, and the loss
  of any single customer would not have a material adverse effect upon the
  overall business of the Okon division. 
  
      The coatings industry in which Okon conducts its business is highly
  competitive and has historically been subject to intense price
  competition.  Other competitive factors include V.O.C. content, product
  quality, product innovation, and distribution.  The competitors number
  between 800 to 900 other coatings manufacturers located throughout the
  United States.  Many competitors are small companies which provide
  intense competition within regional and local markets, especially with
  respect to lower priced coatings and custom made specialty products
  required on a short-time delivery basis.  Other competitors are large
  diversified corporations, with assets substantially greater than those of
  the Company, which compete on a nationwide basis.  The position of Okon
  in the industry is very small.  The Company believes that Okon can
  compete satisfactorily however, especially on the basis of the V.O.C.
  content of its products.
  
       Most of Okon's competitors in the coatings industry use and dispose
  of substances regulated under extensive environmental protection laws.  A
  pervasive system of federal, state and local laws and regulations
  prohibit or limit the discharge of hazardous materials into the
  environment.  In the coatings industry, the regulation of Volatile
  Organic Compounds (V.O.C.) by the U.S. Environmental Protection Agency,
  and increasingly by the states, is an important factor in success. 
  
       Okon's products are water-based and biodegradable, which
  significantly reduces the risks of environmental problems.  Management
  believes that Okon is in compliance with EPA and state regulations
  regarding environmental protection. 
  
       The chemistry of Okon's products exceed current Environmental
  Protection Agency standards for Volatile Organic Compounds (V.O.C.), and
  Rentech's management therefore considers the products to be
  environmentally friendly.  The Company believes that the business is
  well-positioned to take advantage of a nationwide movement by state and
  federal agencies to further regulate and restrict the V.O.C. contents of
  paints, stains and sealers.  The majority of wood stains, concrete stains
  and block pluggers currently on the market contain V.O.C. levels that are
  increasingly considered unacceptable in several regions of the United
  States.  State and federal government agencies have proposed further
  restrictions to limit the levels of V.O.C. contained in products.  The
  restrictions have effectively prohibited the sale and use of high V.O.C.
  products in certain states such as California.

       The environmental advantages of the Okon products complement
  Rentech's original business philosophy of producing environmentally
  cleaner fuels and products from its gas-to-liquids conversion technology. 
  The Company's long-term plan is to establish an environmental and
  industrial products group that includes Okon.
  
  
  Advanced Technologies (ITN Electronic Substrates LLC)
  
       As a step toward its long-term goal of establishing an advanced
  technology group, Rentech agreed in July 1997 with ITN Energy Systems,
  Inc. to enter into a new business called ITN Electronic Substrates LLC. 
  Rentech owns 50% of the LLC, and ITN Energy Systems, Inc., a privately
  owned Colorado corporation, owns 50%.  Rentech is manager of the LLC for
  financial, marketing, and operational matters, and the other member of
  the LLC is manager for technical matters. 
  
      ITN Electronic Substrates LLC's business will be based upon advanced
  technology to be contributed to it by ITN Energy Systems, Inc.  The LLC
  will use the Technology to manufacture and sell flexible thin-film on
  which it has electronically deposited metals with unique properties, such
  as copper and molybdenum, that provide conductive paths to which computer
  chips may be attached.  The Company expects that the LLC will start work
  during the fiscal quarter ending December 31, 1997, on retrofitting its
  thin-film manufacturing machines that will be used to produce its thin-film
  products.  The Company expects the LLC to begin production in 1998. 
  The managers have contacted potential customers for its products, but as
  yet the new LLC has no contracts for purchases of its products.  The
  customers are expected to be contract manufacturers in the computer,
  aerospace and medical instrument industries, as well as large end-users
  which would use the substrates to manufacture their own products. 
  
       Rentech has another agreement with ITN Energy Systems, Inc.
  contemplating co-ownership by them of additional limited liability
  companies that would commercially exploit other advanced technologies
  developed by ITN Energy Systems, Inc.  In October 1996 the two companies
  formed ITN/ES LLC under Colorado law for these purposes.  The potential
  technologies of ITN/ES LLC include advanced processes for ceramic
  deposition on materials to improve their capacity to withstand heat and
  wear, and use of shape memory alloys that are highly advanced metals
  which, by the proper application of heat, cold or electrical impulse can
  perform a mechanical function with precision for long periods of time. 
  
       Rentech's ownership interest in ITN/ES LLC and all of its
  technologies is to be 10%, subject to contribution of $200,000 in cash
  and 1,200,000 shares of Rentech restricted Common Stock.  Rentech is to
  register its shares issued to the LLC within 120 days after issuance, and
  if it has not, is required to issue an additional 400,000 shares to
  ITN/ES LLC as additional consideration.

                                                        PAGE 8
    
       The agreement relating to ITN/ES LLC between ITN Energy Systems,
  Inc. and Rentech recognizes that commercialization of the technologies
  already in existence as well as those that may be developed in the future
  by ITN/ES LLC may require establishment of additional business entities. 
  Rentech by mutual agreement, may provide additional capital to increase
  its ownership interest in the various technologies in which it invests
  with ITN Energy Systems, Inc. 
  
  
  General Arrangements for Licensing the Gas-to-Liquids Technology
  
       The Company's objective for its gas-to-liquids Technology is to
  license the Technology for use in plants to be constructed and financed
  by licensees.  Rentech intends to use the information obtained from
  conducting the demonstration run in the Synhytech plant to encourage
  additional licensees and potential licensees to construct their own
  plants using Rentech's Technology.  Rentech expects that other
  prospective licensees will await completion of the Arunachal Pradesh
  plant in India and its successful operation before they commit to enter
  into licenses of the Technology or begin design work for constructing
  their own plants to use the Rentech Technology. 
  
       Rentech's Technology is innovative, has been presented at energy
  industry conferences, and has become generally known throughout the
  energy industry.  Interested businesses that are potential licensees have
  initiated contacts with the Company.  The Company has also had
  negotiations with potential licensees who were introduced through its
  present licensees. 
  
      Rentech's licensees are responsible for financing, constructing and
  operating their own process plants that use the Rentech Technology and
  catalyst, including payment for the gas conversion reactors that are
  constructed for Rentech to the special design specifications required for
  each plant.  It is the licensee's obligation to obtain the feedstock
  material, either carbon-burning solids or gases, to be used at the
  licensee's plant.  Upon production of liquid hydrocarbons, each licensee
  is responsible for marketing its own products.  
  
       Conversion plants that use the Rentech Technology may be designed to
  produce from several hundred up to one hundred thousand or more barrels
  per day of product.  The smaller plants are expected to be assembled from
  component systems that are trucked into remote locations where
  inexpensive sources of feedstock gas may be available.  Plants with the
  largest production capabilities would have to be constructed directly at
  the sites where they are to be operated.  The cost of constructing
  conversion plants will vary depending upon their production capacity,
  available infrastructure for electrical power, water supplies, roads, gas
  pipelines and the like, location and other factors such as costs of
  financing and whether the feedstock is a gas or carbon-bearing solids
  that must first be converted to gas.
  
  
  
  
  
  
  
  
  
  
  
  
  
  <PAGE>
                                                        PAGE 9
  
       To date, Rentech's licensees and prospective licensees are foreign
  and expect to locate their plants outside the United States.  Many
  foreign nations, such as India, have substantial needs for diesel fuel
  that are not being met at this time.  The designs of plants for use of
  the Rentech Technology are complex.  Business dealings in foreign
  countries, the ability of licensees to obtain financing for construction
  of plants, and the complexity of design are factors that may result in
  delays in the schedules for financing, design, construction and start up
  of operations of a plant following the initial decision to proceed with
  construction.
  
    
  Synhytech Plant
  
       In 1985, Fuel Resources Development Company (Fuelco), a
  wholly-owned subsidiary of Public Service Company of Colorado (PSCo),
  evaluated Rentech's Technology.  In 1986 Rentech granted Fuelco the right
  to obtain an option to license the Technology, and Fuelco continued its
  evaluation.  Fuelco subsequently assisted with construction and operation
  of the second pilot plant in 1989.  Successful operation of that plant
  confirmed the technical feasibility of the Technology, that is, the
  ability of the Technology to convert carbon-bearing gases, and solids
  converted into such gases, that are fed to a conversion plant, into
  valuable liquid hydrocarbons such as diesel fuel, naphthas, and waxes. 
  In 1990 Fuelco began construction of the first full-scale conversion
  plant, located near Pueblo, Colorado.  This plant, called the Synhytech
  plant, cost Fuelco approximately $25 million to construct, maintain and
  operate, and was specifically designed and constructed to use methane gas
  from an adjacent landfill as its feedstock.  The plant was designed and
  built by a contractor for Fuelco to produce 235 barrels of liquid
  hydrocarbons per day.  Fuelco commenced start up operations of the
  Synhytech Plant and first produced liquid hydrocarbons in January 1992. 
  Rentech's Technology, including its synthesis reactors and catalyst,
  performed as expected.  Fuelco was unable, however, to produce enough
  methane from the landfill to operate the plant.  Contrary to the results
  that Fuelco expected based upon previous test drilling into the landfill,
  most of the methane produced by decomposition of the landfill apparently
  escaped into the atmosphere rather than entering the gas gathering
  pipeline that Fuelco had installed in the landfill for delivery of the
  landfill gas to the Synhytech plant.  Further, the composition of the gas
  was considerably different than the gas Fuelco had determined would be
  produced.  Consequently, the gas that was produced was collected in
  inadequate volumes was not a suitable feedstock for the Synhytech plant
  because it did not contain the combination of carbon-bearing materials
  that Fuelco projected and for which the plant was specifically designed. 
  The deficiencies in Fuelco's ability to collect its projected volume of
  landfill gas and in the composition of the landfill gas that it did
  collect have no relation to the technical feasibility of the Rentech
  Technology, which cannot be applied without an adequate volume of gas
  that is the same as that which a plant is designed to use.

       Fuelco constructed a pipeline to bring an expensive and limited
  supply of natural gas to the plant as an alternative feedstock on a
  temporary basis.  Fuelco operated the plant with a mixture of the
  pipeline natural gas and the landfill gas.  Because this temporary gas
  supply was not intended to be a permanent supply due to the high cost of
  the natural gas, because it was delivered under too low a pressure to
  meet the plant's design requirements, and because the natural gas supply
  was subject to cutoff in favor of prior users during periods of high
  demand for gas, Fuelco shut down operations of the plant in May 1992 to
  seek a better feedstock source and to repair mechanical problems in the
  conventional systems of the plant.  In mid-1992, before Fuelco could
  solve these problems, PSCo, as part of its decision to return to its core
  business of producing and selling electricity, decided to divest several
  subsidiary businesses, including its real estate development business and
  Fuelco and its Synhytech operations.  After extensive negotiations based
  upon the potential of claims by Rentech against PSCo and Fuelco, they
  transferred all interests in the Synhytech plant to Rentech in May
  1993, together with associated equipment and assets, including $650,000
  in cash and all the machinery, equipment and other assets assembled by
  Fuelco in Boulder, Colorado to manufacture Rentech's proprietary
  catalyst.  The primary motivation for PSCo to enter into the transfer
  agreement was Rentech's agreement to release its claims that PSCo and
  Fuelco failed to perform under its license agreement with Rentech to
  construct and operate a commercial size plant.  The transfer required no
  cash or stock from Rentech, but instead was based on termination of the
  relationship between the companies and release of Rentech's claims
  against Fuelco and PSCo.  Rentech assumed equipment sublease obligations
  for computers, vehicles and equipment associated with the Synhytech plant
  and agreed to remove the plant and clean up the site upon its final
  decision to discontinue operations of the plant.  Fuelco's 20% interest
  in Rentech's future revenues from royalties and license fees reverted to
  Rentech.  PSCo retained its equity interest in the Company as a
  shareholder. 
  
       In February 1993, Rentech took possession of the Synhytech plant and
  the related assets acquired from Fuelco and Public Service Company of
  Colorado.  Before acquiring the Synhytech plant, Rentech had entered into
  negotiations with prospective licensees that had indicated a substantial
  interest in acquiring licenses if the Company could provide data from
  actual operations of a full-size plant.  In order to provide verifiable
  statistics and evidence for prospective licensees, and to evaluate the
  plant and its components for resale to one or more prospective licensees,
  Rentech decided to operate the plant for a short period of time.  Rentech
  therefore converted the plant during 1993 for use of natural gas rather
  than landfill gas; corrected or resized several items of equipment and
  other associated hardware; and modified several aspects of the
  engineering design used by Fuelco for the conventional systems of the
  plant.  Rentech's costs to convert the plant, including operations during
  the demonstration run and assumption of all obligations for equipment
  leases, gas supply contracts and utilities, were approximately $3.3
  million.

       In accordance with the Company's plan to provide operating data on
  its Technology in a full-size, commercial scale plant and to evaluate the
  plant and its components for resale, Rentech operated the modified
  Synhytech plant successfully in a continuous state for three weeks during
  July and August 1993.  As planned, the plant was then shut down pending a
  decision by Rentech's management regarding its sale or other disposition. 
  During the demonstration phase, the plant operated at design
  specifications, produced the expected range of hydrocarbon products, and
  achieved the design conversion ratios anticipated for Rentech's
  proprietary catalyst used in the conversion process.  The technical data
  collected and initial product test results show the process is feasible
  for commercial exploitation.  The operations produced liquid hydrocarbon
  products, samples of which are available to prospective licensees for
  their evaluation of uses, markets and pricing of the products.  Valuable
  engineering and operational data bearing on the efficiency and economics
  of the Technology were collected and will also be used by licensees in
  the design of their own plants.  Based on these results and the
  observations of them made by several prospective licensees, Rentech was
  able to obtain arrangements for use of its Technology in the Henan Plant
  in China, now deemed terminated for accounting purposes, and a
  preliminary design contract for the Arunachal Pradesh plant under
  construction in India.  See "Description of Business--Present Licenses
  and Contracts for the Gas-to-Liquids Technology."  Rentech expects to
  recover the related costs of the demonstration run in the Synhytech Plant
  over the term of present and expected future license agreements.  
  
       In 1993, the Synhytech plant fulfilled Rentech's purpose of
  demonstrating use of its Technology on a commercial scale that allowed
  collection of data for use by licensees in their plants.  However,
  Fuelco's inability to obtain its projected quantities and adequate
  quality of landfill gas feedstock from the landfill adversely impacted
  the economic viability of the plant, thus preventing it from ever being
  operated at a profit at the Pueblo site.  The Company's present business
  plan for its Technology remains focused on licensing its Technology to
  licensees for plants they construct to use Rentech's gas conversion
  process.  Accordingly, in 1995, Rentech sold the Synhytech plant as a
  whole, except for the buildings used for support activities, to its
  licensee for the India plant.  The plant was dismantled in 1996 and the
  component parts were shipped to India to be used in the plant under
  design for use of the Rentech Technology in Arunachal Pradesh, India. 
  
  
  Present Licenses and Contracts for the Gas-to-Liquids Conversion
  Technology
  
       Several licenses for use of its gas-to-liquids Technology have been
  granted by Rentech, as described in this section.  A license authorizes a
  third party to construct a conversion plant utilizing the Rentech
  Technology.  The license agreements are granted in exchange for license

  fees, engineering design fees, and production royalties based either upon
  a percentage of gross proceeds from the sale of liquid hydrocarbons or
  other products produced through use of the Rentech Technology or based
  upon some other measure of product value.  Licenses may grant either
  exclusive or non-exclusive rights to use the Technology in identified
  countries or other geographic areas.  The license fees and terms are
  individually negotiated and vary among licensees.  
  
       In September 1992 Rentech granted the exclusive right to ITN, Inc.,
  a Colorado corporation, to market the Rentech Technology in the country
  of India to potential owners of Rentech process plants.  ITN, Inc. is
  owned by Dr. Mohan S. Misra, who also owns ITN Energy Systems, Inc., a
  co-owner with Rentech of new limited liability companies that expect to
  enter into business in advanced technologies.  See "Description of
  Business--Advanced Technologies."  If ITN identifies parties who obtain a
  license from Rentech and build a plant or plants in India using the
  Rentech Technology, ITN is entitled to 20% of Rentech's royalty, license
  fee or other revenues from such plants as compensation to ITN.  ITN
  continues to assist with marketing the Rentech Technology in India.
  
       Through the efforts of ITN, Rentech has granted a license for the
  design and construction of a process plant in India using Rentech's
  Technology.  The plant is to be a 360 barrel per day plant, using flared
  gas in the state of Arunachal Pradesh in northeastern India.  The owners
  are Donyi-Polo Petrochemicals, Ltd., the state government of Arunachal
  Pradesh, and Oil India, Ltd., a government of India enterprise.  Gas
  feedstock that is presently flared from oil wells has been allocated to
  this project by the state government of Arunachal Pradesh.  Between
  August 1994 and February 1995, Rentech completed a $300,000 preliminary
  contract for the basic design of the plant that it entered into in 1994
  with the plant owners.  In 1995, Donyi-Polo Petrochemicals, which
  acquired the license from Rentech, purchased Rentech's Synhytech plant
  near Pueblo, Colorado for relocation to Arunachal Pradesh, to reassemble
  it and reuse it there.  Rentech has received $240,000 as payments due
  toward its license fee.  The Synhytech plant, which will provide the
  majority of base components of the India plant, was relocated to the
  Arunachal Pradesh site in India in late 1996.  In addition to the
  $250,000 contract for engineering services awarded to Rentech, Donyi-Polo
  Petrochemicals has contracted with Humphries & Glasgow, Bombay, India,
  for the prime engineering contract and has entered into a contract for
  the design and fabrication of the required wax distillation equipment. 
  The final engineering design is expected to be completed by Humphries &
  Glasgow and construction is expected to commence before the end of 1997. 
  Completion of the plant is not expected until the first part of 1999. 
  The license agreement provides for royalty payments for seven years after
  commencement of construction of production from the plant.  The licensee
  is to construct and operate its own catalyst manufacturing plant, using
  the Company's patents, for the production of catalyst.

       Rentech has been requested by Oil and Natural Gas Commission, the
  state oil company of India, to prepare quotations for the design of two
  gas conversion facilities in India that would use the Rentech Technology. 
  The plans under consideration would be sized to produce 2,800 and 10,000
  barrels per day of production of products from use of the Rentech
  Technology.  No decisions have been made to proceed with these plants,
  and Rentech does not expect engineering design contracts, license fees or
  revenues from them in the foreseeable future.
  
       Several licenses have been allowed by the licensees to expire
  without construction of a plant.  In other cases, the licensees are
  seeking financing or adequate supplies of feedstock.  Some licensees are
  waiting to learn the results of operation of the Arunachal Pradesh plant
  in India or another commercial size plant using the Rentech Technology.
  
  
  Markets and Marketing of Products Produced by the Gas-to-Liquids
  Conversion Technology
  
       The market for diesel fuel is well established, extends worldwide,
  is large, and is expected to increase.  Industry estimates are that 80
  million gallons per day of diesel fuel were produced domestically in the
  United States during 1995.  Recent total distillate fuel oil consumption
  in the United States was approximately 123 million gallons per day, and
  over 700 million gallons per day worldwide. 
  
       Laboratory tests made to determine the fuel properties of the diesel
  fuel produced by use of Rentech's Technology have been made by
  independent testing agencies.  While not exhaustive or definitive from a
  scientific point of view, these tests indicate that it is a
  high-grade diesel fuel that provides environmental advantages over
  regularly available diesel fuel.  Compared to commercial No. 2 diesel
  fuel, the Rentech diesel fuel has four fuel properties that make it less
  polluting.  These are an absence of sulphur, zero percent aromatics by
  volume, higher cetane number, and a lower 90% distillation temperature. 
  During the tests, Rentech's diesel fuel demonstrated significant
  reductions in harmful exhaust gas emissions.  Based on the test reports,
  Rentech's management believes that its diesel fuel has improved
  combustion characteristics as measured by its higher cetane value.
  
       A series of federal statutes known as the Clean Air Act Amendments
  of 1990 and the Energy Policy Act of 1992 and related executive orders
  have established benchmarks for reductions in harmful exhaust emissions
  within the United States.  The U.S. Environmental Protection Agency has
  required reductions in diesel fuel sulphur to 0.05% weight maximum.  The
  state of California, which has more motor vehicles than any other state,
  and several other state and local governments, have also adopted
  legislation establishing allowable levels of exhaust emissions for
  vehicles and businesses.  The California limits include 0.05% sulphur
  weight maximum and lowering aromatics content to a maximum of 10% by
  
  
  
  
  
  
  
  
  
  
  
  
  
  <PAGE>
                                                        PAGE 14
  
  volume.  The legislative goals of the various legislative and regulatory
  requirements are to reduce harmful engine exhaust emissions by reducing
  fuel aromatics by volume, lowering the 90% distillation temperature, and
  reducing the sulphur levels of diesel fuels.  Initial studies as to the
  requirements of California and other jurisdictions have shown that
  emissions of hydrocarbons, carbon monoxide, oxides of nitrogen, and
  particulate matter seem to be reduced by a reduction in fuel aromatics.
  Higher cetane numbers were found to reduce hydrocarbon and carbon
  monoxide emissions.  Lowering the sulphur content of diesel fuel helped
  reduce particulate matter emissions.
  
       Based on the fuel characteristics tests previously described in this
  section, Rentech's diesel fuel would seem to have many of the qualities
  that the emerging legislation requires.  Before Rentech's diesel fuel
  could be said to be a practical solution to the air emission problems,
  however, long-term engine wear tests are necessary.  Studies conducted
  during the last few years by several companies on commonly available
  diesel fuels that have low aromatics and low sulphur content show that
  such fuels may cause premature mechanical failure of some engine parts,
  particularly fuel injection pumps.  However, low sulphur fuel produced
  from low sulphur crude oil has been used for many years without any
  noticeable increase in engine failures.  Industry studies indicate that
  increased risk of premature failure of certain classes of fuel injection
  pumps may be caused by the severe hydrotreating step used by other
  companies that is necessary to reduce both the aromatic content as well
  as the sulphur content of commonly available diesel fuel.  The Company's
  Technology used to produce its aromatic and sulphur free diesel fuel from
  synthesis gas does not require the severe hydrotreating step. 
  
       Some fuel industry researchers have suggested the use of additives
  to diesel fuels that meet the new regulatory standards as a means of
  reducing fuel system wear.  Additives would increase the cost of such
  fuels, including Rentech's diesel fuel, if that proved necessary, but
  preliminary work and studies by others indicate the cost of additives
  would not be so material as to substantially impact present costs. 
  Rentech's management believes that its diesel fuel can best be used for
  blending with readily available diesel fuel to reduce the visible and
  invisible contaminants in exhaust gases produced by combustion engines. 
  
       Unlike alternative fuels such as methanol and compressed natural
  gas, Rentech's diesel fuel does not require any engine or vehicle
  modification for use.  Fuel mileage may be slightly decreased, although
  minor engine adjustments are expected to increase the fuel mileage to the
  level provided by regularly available diesel fuel.  
  
       Rentech has no arrangements by which vehicle manufacturers have
  approved the use of its fuel and no arrangements for the sale of its
  products.  It is not aware of any reason why its fuel would not be
  readily saleable and would not command a premium price compared to
  current diesel fuel prices.

                                                        PAGE 15
  
       Rentech's Technology also produces naphthas, which are liquid
  hydrocarbon products that are lighter than diesel fuel.  Naphthas are
  used extensively in manufacturing processes for products as diverse as
  paint, printing ink, polish, adhesives, perfumes, glues and fats. 
  Naphthas produced at conversion plants using the Rentech Technology are
  expected to be in demand due to their lower toxicity and lower aromatic
  content than other naphthas.  Rentech's management is aware of at least
  one major urban area that limits the amounts of aromatics in naphthas due
  to environmental concerns.  The U.S. market for one type of naphtha that
  can be produced using the Rentech Technology is estimated at 60,000
  barrels per day.
  
       The wax products produced by the Rentech Technology are expected to
  be the most valuable products on a unit basis because the existing market
  prices for waxes are higher for each barrel of wax than for naphthas or
  diesel fuel.  Rentech has contacted at least three potential buyers for
  large quantities of its wax, and determined that they are interested in
  the quality and quantity of the wax that would be available after
  production begins.  There are at this time no contracts with purchasers
  of the wax.
  
       If required, the conversion process in plants using the Rentech
  Technology can be easily modified to produce a light crude oil for sale
  to refineries.  Rentech's Technology produces a high-grade crude oil,
  already partially refined, that management believes could be
  inexpensively refined in existing refineries into gasoline and other
  petroleum products for which the markets are well developed and
  extensive.
  
  
  Competition for the Gas-to-Liquids Technology
  
       Rentech and its licensees are subject to substantial competition,
  especially for the products of its Technology.  Competition in the diesel
  fuel market is largely a function of price.  Thus, the Company's future
  success will depend upon whether or not its Technology will enable
  production of the liquid hydrocarbons at a cost that will allow them to
  be profitably sold.  Downward movements in the price of diesel fuel,
  naphtha or waxes could have an adverse impact upon operations of the
  Company.
  
       Several major oil companies are involved in large-scale synthetic
  fuel development, such as The Royal Dutch Shell Oil Company, Exxon
  Corporation, and Statoil, the national oil company of Norway.  The
  largest user of similar technology is South African Synthetic Oil, Ltd.
  (SASOL), a South African company that is engaged in coal gasification to
  produce synthesis gas that is converted by Fischer-Tropsch reactions into
  synthetic fuel. 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  <PAGE>
                                                        PAGE 16
  
       Rentech's management believes that its patents protect several
  unique features of its Technology and catalyst that give it competitive
  advantages in costs and end products over those of its competitors.  See
  "Description of Business--Patents Relating to the Gas-to-Liquids
  Technology."  However, most companies that do or may compete with Rentech
  are well established and have substantially greater financial, marketing,
  personnel and other resources than does the Company.  No assurance can be
  given that Rentech will be able successfully to compete on a price basis
  with either synthetic or natural fuels.
  
  
  Catalyst Production for the Gas-to-Liquids Technology
  
       Use of the Company's Technology requires use of its proprietary
  catalyst.  After several plants are in operation and the volume of
  catalyst that is required justifies the capital cost of a catalyst
  manufacturing facility, Rentech plans to manufacture its proprietary
  catalyst and provide it to its licensees for cost plus a reasonable
  profit.  Until Rentech develops its own manufacturing capability, the
  catalyst is to be produced by an independent catalyst manufacturer under
  license from Rentech.  
  
  
  Feedstock Supplies for the Gas-to-Liquids Technology
  
       The Company's licensees of its Technology are responsible for
  obtaining their own supplies of carbon-bearing, low-cost feedstock,
  usually in substantial quantities.  Economic use of the Rentech
  Technology depends upon inexpensive sources of feedstock.  Management
  believes such feedstock will be readily available to its licensees from
  inexpensive sources such as natural gas wells that are not producing or
  that flare gas or that produce gas that is not suitable for commercial
  sale.
  
      A potential feedstock that is of growing importance is the heavy high
  sulphur residual fuels at refineries ("refinery bottoms ").  Within the
  next ten years a large surplus of high sulphur residue is predicted which
  cannot be absorbed by the market.  Conversion of such fuels to synthesis
  gas by conventional gasification technologies is an attractive option. 
  The synthesis gas, a mixture of hydrogen and carbon monoxide, with its
  low hydrogen-to-carbon monoxide ratio, is an excellent feedstock source
  for conversion into liquid hydrocarbons by the application of the
  Company's Technology.  The hydrocarbon products, as well as other
  byproducts such as the excess steam and hydrogen produced by the process,
  can all be utilized at the refinery.  The diesel fuel fraction is an
  excellent blending stock to upgrade non-specification fuels or to improve
  the quality of the commercial diesel currently being produced in
  refineries by lowering the aromatic and sulphur content and increasing
  the cetane index.  Rentech has patented the blending of its Fischer-Tropsch
  diesel fuel with commercial diesel to reduce harmful emissions. 
  
  
  
  
  
  
  
  
  
  
  
  
  <PAGE>
                                                        PAGE 17
  
      Additional sources of feedstock include methane gas collected from
  coal beds and industrial off gases.  Carbon-bearing solids such as coal,
  biomass and other carbonaceous materials that, like natural gas and
  refinery residues must first be converted to synthesis gas, can provide
  another feedstock source. 
  
  
  Patents Relating to the Gas-to-Liquids Technology
  
       Rentech has been granted eight United States patents related to
  certain process applications, products produced, and materials used in
  its gas conversion process.  The patents are directed to technology in
  the field of conversion of gaseous hydrocarbons to liquid hydrocarbons
  through use of Fischer-Tropsch processes in slurry bed reactors. 
  Additional patent applications have been filed. 
  
       The present patents include a method for cracking a Fischer-Tropsch
  wax, a method of making and promoting a promoted iron catalyst for use in
  slurry Fischer-Tropsch synthesis reactors, a synthetic oxygenated diesel
  fuel produced by Fischer-Tropsch synthesis, an oxygenated diesel fuel to
  be used as an additive, the overall gas-to-liquids conversion process,
  and Rentech's oxygenated, sulphur and aromatic-free diesel fuel for use
  as an additive.  The latter patent solidifies Rentech's previous patent
  relating to use of its diesel fuel as an additive, which increases the
  oxygen content in diesel fuel while maintaining diesel fuel specification
  limits for viscosity. 
  
       Two of the patents include key elements of the process that enables
  Rentech's iron-based catalyst to compete with cobalt-based catalysts used
  by others with gas conversion processes.  These patents protect process
  steps that improve Rentech's carbon conversion efficiency by over 30%. 
  Because Rentech's iron-based catalyst is significantly less expensive
  than cobalt catalysts, the improvement in conversion efficiency makes
  Rentech's process cost-competitive.  Additionally, cobalt catalysts used
  by others, due to the toxicity of the catalysts, are less environmentally
  friendly because they create a waste hazard for their users.  By
  comparison, Rentech's iron-based catalyst can be disposed of in a
  landfill with no environmental regulation or concerns.  These factors
  make the Rentech process more cost-effective and environmentally safe for
  converting gases containing hydrocarbons to liquids while allowing
  Rentech's end products to be competitively priced with products from
  crude oil or other products made from Fischer-Tropsch processes. 
  
       The issuance of patents to the Company does not assure it that
  competitors or licensees will not engage in infringement of such patents,
  especially outside the United States where rights to technology are
  generally not as well protected as in the United States.  There are no
  assurances that the Company's patents will not be challenged, invalidated
  or circumvented, that the rights granted by the patents will provide
  competitive advantages to the Company, or that the Company's efforts to
  protect its intellectual property rights will be successful.

  Governmental Regulations Pertaining to the Gas-to-Liquids Technology
  
       Conversion plants using the Rentech Technology and plants
  manufacturing Rentech's proprietary catalyst are subject to federal,
  state and local laws, rules and regulations relating to occupational
  health and safety as well as those regulating protection of the
  environment.  Compliance with such requirements is not expected to
  require significant capital expenditures by Rentech and is the
  responsibility of the licensees that own and operate the plants.
  
  
  Research and Development Pertaining to the Gas-to-Liquids Technology
  
      The Company had no expenses for research and development during the
  twelve-month period ended September 30, 1997, and none during the
  9-month fiscal period ended September 30, 1996. 
  
  
    Employees
    
         At present, the Company has fifteen full-time employees, eight of
    whom are employed by Okon. 
    
    
    Item 2.  Description of Property
  
    Synhytech Plant Buildings
    
         Two industrial buildings formerly used to support operations
    of the Synhytech plant are located in Pueblo, Colorado, on land leased
    from Public Service Company of Colorado and its subsidiary, Fuel
    Resources Development Company, that is owned by the City of Pueblo. 
    Rentech expects to either sell or lease the buildings on site,
    depending upon reaching agreement with the City of Pueblo for the city
    to sell the land on which they are located to buyers of the buildings,
    or if no agreement is reached, to sell the buildings for disassembly,
    relocation and reuse off the site.  If the buildings are sold to be
    relocated, the buyer will be required to remove the buildings. 
  
  
    Office Lease
    
         The executive offices of the Company are located in Denver,
    Colorado and consist of approximately 2,977 square feet of office
    space.  The lease expires in November 1999 and includes an option to
    extend for another five-year term. The rent is approximately $39,000
    per year.

    Okon Facility
  
         Okon rents an industrial building located in Lakewood,
    Colorado, where it conducts its operations.  The building contains
    approximately 12,000 square feet of office and warehouse space.  The
    lease expires March 14, 1999 and includes an option to extend for a

         Based solely upon the number of record holders, the approximate
    number of shareholders of the common stock of the Company as of
    September 30, 1997 was 337.  The number of beneficial owners is
    estimated by management at not less than 1,400. 
    
         No dividends have been declared during the 12-month fiscal year
    ended September 30, 1997 and the 9-month fiscal period ended September
    30, 1996, with respect to the common stock.
    
         The Nasdaq Stock Market has increased its financial requirements
    as of January 1998 for companies whose stocks are listed on Nasdaq. 
    Among several changes, one makes stocks trading at less than $1
    ineligible for listing, and another increases the total assets
    requirement to $3 million.  At present Rentech meets all of the new
    requirements, but there are no assurances that the Company will
    continue to meet the listing requirements.  If it does not, the common
    stock would be dropped from Nasdaq's SmallCap Market after a grace
    period.  The effect of delisting would have a material adverse effect
    upon ability of shareholders to sell their stock and upon the value of
    the stock.

<F1>   Notes in the original principal balance of $620,500 are convertible into shares of Common Stock at $.33 per
share until April 16, 1998.  If not converted by the note holders by then, and if the Company does not pay the note in
cash at that time, the note holders may convert their notes into Common Stock at 70% of the average closing bid price
for the 5 trading days prior to conversion, not to exceed $33 a share.  The placement agent was
Neidiger/Tucker/Bruner, Inc., Denver, Colorado.  In addition to the placement fees paid in cash, the placement agent
received a warrant, exercisable for 5 years, to purchase the Company's convertible promissory note in the amount of
$58,500.  The note is convertible, for 180 days from exercise of the warrant, at the same price and conversion terms
as the other notes issued in the private placement.

  Item 6.  Management's Discussion and Analysis or Plan of Operation
  
  Results of Operations
  
         For the year ended September 30, 1997 and the nine month period ended
  September 30, 1996, the Company had net losses of $1,375,686 and $392,478,
  respectively.  The increase of approximately 350% in loss for the twelve
  month period in 1997 compared to the nine month period in 1996 is due to a
  decrease in contract revenues and license fees of $295,176, increase in
  interest expense of approximately $289,000 from the addition of $1,250,500
  in debt and extraordinary gain in 1996 of $200,434.  Increases in 1997 costs
  over 1996 are attributable in general to the longer fiscal period in 1997
  and in particular to public relations costs, and approximately $100,000 in
  hiring costs of a chief financial officer.  Profit contributed by Okon from
  its acquisition in March 1997 partially offset the increases in costs due to
  the longer fiscal period. 
  
         During the year ended September 30, 1997, the Company did not
  recognize any contract revenues related to the Arunachal Pradesh plant under
  construction in India.  Contract revenues of $55,176 were recognized during
  the nine months ended September 30, 1996. 
  
         During the year ended September 30, 1997, no revenue was recognized
  for license fees compared to $240,000 for license fees from Donyi Polo
  Petrochemicals Ltd., an Indian corporation, for grant of a license to use
  the Company's gas conversion technology in the plant under construction by
  Donyi Polo at Arunachal Pradesh, India.  Donyi Polo purchased the Company's
  Synhytech plant located at Pueblo, Colorado during 1995, dismantled it and
  shipped the component parts and systems to India in 1996 for reassembly and
  use as the basis of the Arunachal Pradesh plant. 
  
         During the year ended September 30, 1997, the Company recognized
  $1,189,536 for sales of water-based paints, sealers and coatings for a six
  and one-half month period commencing March 16, 1997 as compared to no income
  for the nine month period ended September 30, 1996.  This increase reflects
  the purchase of Okon in March 1997. 
  
         During the year ended September 30, 1997, no costs were incurred for
  cost of contracts compared to $29,463 incurred in the nine months ended
  September 30, 1996. 
  
         During the year ended September 30, 1997, costs of sales related to
  the water-based paints, sealers and coatings was $481,796 as compared to no
  costs for the nine months ended September 30, 1996.  This increase reflects
  the purchase of Okon in March 1997. 
  
         The gross profit of $707,739 for the year ended September 30, 1997 is
  primarily a result of sales of water-based paints, sealers and coatings for
  a six and one-half month period since the acquisition of Okon.  The gross
  profit of $265,713 for the nine months ended September 30, 1996 is a result
  of the license fees and engineering design and consulting contract for the
  Indian plant. 
  
         During the year ended September 30, 1997, general and administrative
  expenses increased by 133% over the nine month period ended September 30,
  1996.  The increase is caused by approximately $366,000 in expenses
  
  
  
  
  <PAGE>
                                                        PAGE 23
    
  associated with Okon which were not included in the prior period, increased
  costs related to public relations, approximately $100,000 in expense from
  the hiring of a chief financial officer during 1997, and by the longer
  fiscal period in 1997 during which costs were incurred. 
  
         Depreciation and amortization increased 37% during the year ended
  September 30, 1997 compared to the nine months ended September 30, 1996
  primarily due to the longer period during which equipment was depreciated
  and licensed technology was amortized and due to depreciation of Okon's
  equipment and amortization of goodwill acquired when Okon was purchased in
  March 1997. 
  
         Loss from operations for the year ended September 30, 1997 increased
  by $523,984 to a loss of $1,077,783 compared to a loss of $553,799 for the
  nine months ended September 30, 1996.  The increased loss is primarily due
  to a decrease in revenue from contracts and license fees, increases in
  general and administrative expenses and depreciation and amortization,
  combined with the cost impact of a longer operating period.  This increase
  is partially offset by an operating profit contributed by Okon, which was
  acquired in March 1997. 
  
         Gain of $3,140 on sale of fixed assets for the nine months ended
  September 30, 1996 reflects sale of an individual component of the Synhytech
  plant that was not purchased for relocation to India.  During the nine
  months ended September 30, 1996, the Company recognized a write-down of
  $100,000 on the Synhytech plant held for sale.  During the nine months ended
  September 30, 1996 the Company had $71,813 in other income from refund of a
  property tax paid in a prior period.  Interest expense increased by
  approximately $293,000 during the twelve months ended September 30, 1997
  compared to the nine month period ended September 30, 1996 due to the
  addition of $1,250,500 in debt.  Interest expense in the prior year is due
  to $798,750 in convertible notes that were converted into the Company's
  common stock during September 1996. 
  
  
  Liquidity and Capital Resources
  
         The Company has a working capital deficit of $675,630 and has
  incurred losses since its inception that raise substantial doubt about its
  ability to continue as a going concern.  At September 30, 1997 the Company
  had a working capital deficit of $675,630 as compared to working capital of
  $456,560 at September 30, 1996.  The decrease in working capital is
  primarily due to the addition of $1,250,500 in debt that comes due within
  one year, partially offset by the working capital of Okon.  $560,500 of the
  $1,250,500 in current portion of long-term debt is convertible into the
  Company's common stock at the Company's option if not converted by the
  noteholders by April 16, 1998 and if the Company does not pay the debt in
  cash at that time. 
  
         The cash realized by the Company during the fiscal year ended
  September 30, 1997 and the cash generated from Okon's operations are
  expected to be adequate to fund the Company's operations at the current
  level through the first half of the 1998 fiscal year.  In order to realize
  revenues from the Company's interests in ITN Electronic Substrates LLC,
  which intends to manufacture and sell flexible thin-film, and from ITN/ES
  
  
  
  
  <PAGE>
                                                        PAGE 24
    
  LLC, which intends to manufacture and sell a heat pump, the Company requires
  additional working capital.  The Company expects to make one or more private
  placements of its securities that would be convertible into common stock at
  a discount from the market price.  
  
       The net proceeds of the private placement would also be applied to pay
  off the Company's indebtedness.  There are no assurances that additional
  capital will be raised or that the businesses that the Company intends to
  develop will generate operating income to the Company in time or in amounts
  adequate to enable the Company to continue its operations as a going
  concern. 
  
         The Company expects to realize income during the next 18 months from
  its license granted for the plant at Arunachal Pradesh in India.  The
  Company expects to receive license fees in the amount of $240,000, and
  additional fees for engineering services are expected although not yet under
  contract.  Income from royalties associated with the India plant are not
  expected until after the completion of construction and startup and
  operation of the plant.  Construction is not expected to be completed until
  the first part of 1999. 
  
         The Company is discussing other proposals made by several energy
  companies, including Texaco Group, Inc., for exploitation of the Company's
  gas-to-liquids Technology through licenses or other business ventures.  No
  assurances can be made that these discussions will result in either business
  ventures or revenues to the Company.  
  
         The Company has made no commitments for material capital
  expenditures, either in the short or long term.  Management does not
  presently expect to make such commitments in the near future. 
  
         The Company has deferred tax assets with a 100% valuation allowance
  at September 30, 1997 and 1996.  Management is not able to determine if it
  is more likely than not that the deferred tax assets will be realized. 
  
  
                              Analysis of Cash Flow
  
         The Company had net losses from operations of $1,375,686 during the
  year ended September 30, 1997, and $392,478 during the nine months ended
  September 30, 1996.  During the year ended September 30, 1997, non-cash
  expenses included depreciation, which was 41% more, and amortization, which
  was 37% more, than during the nine month period in 1996, primarily due to
  the longer period during which equipment was depreciated and licensed
  technology was amortized, as well as depreciation of Okon's equipment and
  amortization of goodwill acquired when Okon was purchased in March 1997 and
  interest expense which was paid by issue of options to purchase common stock
  at market value.  Also during the year ended September 30, 1997, the Company
  incurred $274,539 in noncash interest expense associated with its
  convertible notes payable and issued stock options for services valued at
  $45,028.  The Company recorded a $100,000 write-down of the Synhytech plant
  held for sale and a gain of $3,140 on sale of assets due to sale of the
  Synhytech plant and issued shares to discharge $152,152 for services during
  the nine month period ended September 30, 1996.

                                                        PAGE 25
    
       Changes in operating assets and liabilities are primarily due to
  accounts receivable, inventories, prepaid expenses and accrued liabilities
  acquired with the operations of Okon.  Property tax refund receivable
  recorded during the nine months ended September 30, 1996 was received during
  the year ended September 30, 1997.      The total net cash used in
  operations increased by 53% to $753,324 in the year ended September 30, 1997
  compared to an increase of $493,234 during the nine months ended September
  30, 1996.  The increase reflects increased cash costs for general and
  administrative expenses partially offset by cash contribution from Okon
  since its acquisition in March 1997 and increased due to the longer fiscal
  period. 
  
       Investing activities during the year ended September 30, 1997 included
  purchase of $65,815 in equipment compared to no purchases in the prior
  period.  The Company used $1,075,739 in cash to acquire the assets of Okon
  during the year ended September 30, 1997.  There were no acquisitions in the

  cash of $25,000 during the 1997 period compared to no reduction in
  restricted cash during the 1996 period.  Other assets increased by $23,901
  during the 1997 period compared to a decrease of $2,433 in the 1996 period,
  primarily due to preliminary investments in future joint ventures. 
  
       Financing activities during the year ended September 30, 1997 produced

  September 30, 1997 from $210,486 at September 30, 1996.
  
       The Financial Accounting Standards Board ("FASB") recently issued
  Statement of Financial Accounting Standards No. 128 "Earnings Per Share"
  (SFAS 128") and Statement of Financial Accounting Standards No. 129
  "Disclosure of Information About an Entity's Capital Structure ("SFAS 129"). 
  SFAS 128 provides a different method of calculating earnings per share than
  is currently used in accordance with Accounting Board Opinion ("ABP") No.
  15, "Earnings Per Share."  SFAS 128 provides for the calculation of "Basic"
  and "Diluted" earnings per share.  Basic earnings per share includes no
  dilution and is computed by dividing income available to common stock
  holders by the weighted average number of common shares outstanding for the
  period.  Diluted earnings per share reflects the potential dilution of
  securities that could share in the earnings of an entity, similar to fully
  diluted earnings per share.  SFAS 129 establishes standards for disclosing

  information about an entity's capital structure.  SFAS 128 and SFAS 129 are
  effective for financial statements issued for periods ending after December
  15, 1997.  Their implementation is not expected to have a material adverse
  effect on the consolidated financial statements. 
  
       In June 1997, FASB issued Statement of Financial Accounting Standard
  No. 130 "Reporting Comprehensive Income ("SFAS 130") and Statement of
  Financial Accounting Standard No. 131 "Disclosures about Segments of an
  Enterprise and Related Information ("SFAS 131").  SFAS 130 establishes
  standard for reporting and display of comprehensive income, its components
  and accumulated balances.  Comprehensive income is defined to include all
  changes in equity except those resulting from investments by owners and
  distributions to owners.  Among other disclosures, SFAS 130 requires that
  all items that are required to be recognized under current accounting
  standards as components of comprehensive income be reported in a financial
  statement that displays with the same prominence as other financial
  statements.  SFAS 131 supersedes Statement of Financial Accounting Standard
  No. 14 "Financial Reporting for Segments of a Business Enterprise."  SFAS
  131 establishes standards of the way the public companies report information
  about operating segments in annual financial statements and requires
  reporting of selected information about operating segments in interim
  financial statements issued to the public.  It also establishes standards
  for disclosures regarding products and services, geographic areas and major
  customers.  SFAS 131 defines operating segments as components of a company
  about which separate financial information is available that is evaluated
  regularly by the chief operating decision maker in deciding how to allocate
  resources and in assessing performance.  
  
       SFAS 130 and SFAS 131 are effective for financial statements for
  periods beginning after December 15, 1997 and require comparative
  information for earlier years to be restated.  Because of the recent
  issuance of these standards, management has been unable to fully evaluate
  the impact, if any, the standards may have on future financial statement
  disclosures.  Results of operations and financial position, however, will be
  unaffected by the implementation of these standards. 
  
  
  Item 7.  Financial Statements
  
       The financial statements identified in Item 13 are filed as part of
  this Annual Report on Form 10-KSB.
  
  
  Item 8.  Changes in and Disagreements with Auditors on Accounting and
             Financial Disclosure
  
       The Company has not had a change of its independent auditors  during
  its two most recent fiscal years or subsequent interim period, except that
  on January 1, 1996, the Company's auditors, Mitchell - Finley and Company,
  P.C. combined their practice into BDO Seidman, LLP.  Thereafter BDO
  Seidman, LLP became the Company's independent auditors for the next two
  fiscal periods ended September 30, 1996 and 1997.  The Company has not
  reported disagreement with its auditors on any matter of accounting
  principles or practices or financial statement disclosure.

  Section 16(a) Beneficial Ownership Reporting Compliance
  
         Based solely upon the Company's review of Securities and Exchange
  Commission Forms 3 and 4 and amendments to those forms submitted to it
  during the most recent fiscal year, the Company has identified the following
  person who was at any time during the fiscal year a director, officer, or
  beneficial owner of more than 10% of any class of equity securities that
  failed to file such forms on a timely basis with the SEC, as required by
  Section 16(a) of the Securities Exchange Act, during the most recent fiscal
  year or prior fiscal years:  James P. Samuels failed to timely file one
  Form 4 due by September 10, 1997 to report one transaction, the acquisition
  of a promissory note convertible into common stock acquired on August 15,
  1997.  The required report was filed on October 10, 1997. 
  
         No arrangements exist between directors, officers or other persons
    which resulted in the selection or election of any of them.  There are no
    family relationships among the executive officers and directors.  All
    directors are elected for three-year terms expiring at the annual meeting
    of shareholders or until their successors are elected and qualified. 
    Officers serve at the pleasure of the board of directors, but have
    employment contracts, as subsequently described.

       The Company has adopted a profit-sharing plan for the benefit of all
  employees.  The plan will be administered by a committee appointed by the
  board of directors.  Awards by the committee to its members will be

       Mark S. Bohn, a director, performed engineering consulting services

  of cash payment, was issued 91,046 shares of restricted stock and warrants

       During the nine months ended September 30, 1996 certain sums that the
  Company owed its officers for salaries were discharged by the issuance of

  promissory note due February 15, 1998.  All notes bear interest at 20% per

  and accumulated interest are due, then interest will be paid on the total
  amount due at an annual rate of 24%.  Additionally options to purchase
  55,000 shares of common stock at the then-market price of $.25 per share
  were granted for each $100,000 of the loan.

  Report of Independent Certified Public Accountants
  
  
  Stockholders and Board of Directors
  Rentech, Inc.
  Denver, Colorado
  
  We have audited the accompanying consolidated balance sheets of Rentech,
  Inc. and Subsidiary (the "Company") as of September 30, 1997 and 1996, and
  the related consolidated statements of operations, stockholders' equity and
  cash flows for the year ended September 30, 1997 and for the nine months
  ended September 30, 1996.  These consolidated financial statements are the
  responsibility of the Company's management.  Our responsibility is to
  express an opinion on these consolidated financial statements based on our
  audits. 
  
  We conducted our audits in accordance with generally accepted auditing
  standards.  Those standards require that we plan and perform the audit to
  obtain reasonable assurance about whether the consolidated financial
  statements are free of material misstatement.  An audit includes examining,
  on a test basis, evidence supporting the amounts and disclosures in the
  consolidated 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 audits provide a reasonable basis for our opinion. 
  
  In our opinion, the consolidated financial statements referred to above
  present fairly, in all material respects, the financial position of the
  Company and its subsidiary as of September 30, 1997 and 1996 and the results
  of their operations and their cash flows for the year ended September 30,
  1997 and for the nine months ended September 30, 1996, in conformity with
  generally accepted accounting principles. 
  
  The accompanying consolidated financial statements have been prepared
  assuming that the Company will continue as a going concern.  As discussed in
  Note 1 to the consolidated financial statements, the Company has a working
  capital deficit and has suffered recurring losses from operations that raise
  substantial doubt about its ability to continue as a going concern. 
  Management's plans in regard to these matters are also discussed in Note 1. 
  The consolidated financial statements do not include any adjustments that
  might result from the outcome of this uncertainty.

 Rentech, Inc. and Subsidiary
 Summary of Accounting Policies
 
 
 Basis of Presentation
 
 Rentech, Inc. (the "Company") was incorporated on December 18, 1981 in the
 state of Colorado to develop and market processes for conversion of low-value,
 carbon-bearing solids or gases into valuable liquid hydrocarbons,
 including high-grade diesel fuel, napthas and waxes ("Rentech Technology"). 
 The Company's activities prior to 1994 were primarily directed toward
 obtaining financing, licensing its technology to third parties and
 completing full-scale plant processing to demonstrate the Company's
 technology to prospective licensees.  During 1994, the Company entered into
 contracts to provide basic engineering design relating to the construction
 of plants using the Company's gas conversion technology (see Note 3).  In
 December 1996, the Company elected to change its year end to September 30.
 In March 1997 with the acquisition of Okon, Inc. ("Okon") (see Note 2), the
 Company entered into the business of manufacturing and selling water-based
 stains, sealers and coatings. 
 
 
 Principles of Consolidation
 
 The accompanying consolidated financial statements include the accounts of
 the Company and its wholly owned subsidiary as of September 30, 1997 and
 for the period from March 20, 1997, date of acquisition of Okon, to
 September 30, 1997 (see Note 2).  All significant intercompany accounts and
 transactions have been eliminated in consolidation.
 
 
 Cash Equivalents
 
 The Company considers highly liquid debt instruments purchased with
 original maturities of three months or less and money market accounts to be
 cash equivalents. 
 
 
 Inventories
 
 Inventories, which consist of water protection sealants, chemicals and
 packaging supplies, are recorded at the lower of cost (first-in, first-out)
 or market.
 
 
 Licensed Technology
 
 Licensed technology represents costs incurred by the Company primarily for
 the purpose of demonstrating the Company's proprietary technology to
 prospective licensees, which it licenses to third parties under various fee
 arrangements.  These capitalized costs are carried at the lower of
 amortized cost or net realizable value and are being amortized over 15
 years.

 The Synhytech plant held for sale is recorded at the lower of cost or net
 realizable value.
 
 
 Property and Equipment
 
 Property and equipment is stated at cost.  Depreciation and amortization
 expense are computed using the straight-line method over the estimated
 useful lives of the assets, which range from three to seven years, except
 for leasehold improvements which are amortized over the shorter of the
 useful life or the remaining lease term.  Maintenance and repairs are
 expensed as incurred.  Major renewals and improvements are capitalized. 
 When property and equipment is retired or otherwise disposed of, the asset
 and accumulated depreciation or amortization are removed from the accounts
 and the resulting profit or loss is reflected in operations. 
 
 
 Long-Lived Assets
 
 Long-lived assets, identifiable intangibles, and associated goodwill are
 reviewed for impairment whenever events or changes in circumstances
 indicate that the carrying amount may not be recoverable.  If the expected
 future cash flow from the use of the assets and its eventual disposition is
 less than the carrying amount of the assets, an impairment loss is
 recognized and measured using the asset's fair value.
 
 
 Revenue Recognition
 
 The Company reports its contract revenue on fixed-priced contracts using
 the percentage-of-completion method of accounting measured by the
 percentage of job costs incurred to date to the latest estimated cost to
 complete for each project.  Job costs incurred prior to the Company's
 entering into a contract are expensed as incurred and excluded from the
 percentage-of-completion calculation. 
 
 Contract costs include all direct material, labor, travel and other costs
 directly related to contracts and indirect costs.  Indirect costs include
 all other costs indirectly related to contract completion such as indirect
 labor, supplies, tools and equipment rental. 
 
 Changes in job performance, job conditions, and estimated final
 profitability, including final contract settlements that may result in
 revisions to costs and earnings are recognized in the period in which the
 revisions are determined.

 License fees are recognized when the revenue earning activities that are to
 be provided by the Company have been performed and no future obligation to
 perform services exist. 
 
 Sales of water-based stains sealers and coatings are recognized when the
 goods are shipped to the customers.
 
 
 Income Taxes
 
 The Company accounts for income taxes under Statement of Financial
 Accounting Standards No. 109 ("SFAS No. 109"). Temporary differences are
 differences between the tax basis of assets and liabilities and their
 reported amounts in the financial statements that will result in taxable or
 deductible amounts in future years.
 
 
 Net Loss Per Common Share
 
 The net loss per share of common stock is determined using the
 weighted-average number of shares outstanding during the period.  Options for
 common stock and warrants are not considered in the computation of net loss
 per share as their inclusion would be antidilutive.
 
 
 Reclassifications
 
 Certain reclassifications have been made to the 1996 financial statements
 in order for them to conform to the 1997 presentation.  Such
 reclassifications have no impact on the Company's financial position or
 results of operation. 
 
 
 Concentrations of Credit Risk
 
 The Company's financial instruments that are exposed to concentrations of
 credit risk consists primarily of cash and accounts receivable. 
 
 The Company's cash is in demand deposit accounts placed with federally
 insured financial institutions.  Such deposit accounts at times may exceed
 federally insured limits.  The Company has not experienced any losses on
 such accounts. 
 
 Concentrations of credit risk with respect to accounts receivable are
 higher due to a few customers dispersed across geographic areas.  The
 Company reviews a customer's credit history before extending credit and
 establishes an allowance for doubtful accounts based upon the credit risk
 of specific customers, historical trends and other information.  Generally,
 the Company does not require collateral from its customers.

 Use of 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, the
 disclosure of contingent assets and liabilities at the date of the
 financial statements, and the reported amounts of revenues and expenses
 during the reporting period.  Actual results could differ from those
 estimates. 
 
 
 Fair Value of Financial Instruments
 
 The following methods and assumptions were used to estimate the fair value
 of each class of financial instruments for which it is practicable to
 estimate that value:
 
 
 Accounts Receivable, Accounts Payable and Accrued Liabilities
 
 Fair values of accounts receivables, accounts payable, and accrued
 liabilities are assumed to approximate carrying values for these financial
 instruments since they are short term in nature and their carrying amounts
 approximate fair value or they are receivable or payable on demand.
 
 
 Convertible Notes Payable, Notes Payable and Long-Term Debt
 
 Substantially all of these notes bear interest at a floating rate of
 interest based upon current lending rates of interest.
 
 
 Stock Option Plan
 
 The Company applied APB Opinion 25, "Accounting for Stock Issued to
 Employees", and the related Interpretation in accounting for all stock
 option plans.  Under APB Opinion 25, no compensation cost has been
 recognized for stock options issued to employees as the exercise price of
 the Company's stock options granted equals or exceeds the market price of
 the underlying common stock on the date of grant.
 
 SFAS No. 123, "Accounting for Stock-Based Compensation", requires the
 Company to provide pro forma information regarding net income as if
 compensation cost for the Company's stock options plans had been determined
 in accordance with the fair value based method prescribed in SFAS No. 123. 
 To provide the required pro forma information, the Company estimates the
 fair value of each stock option at the grant date by using the Black-Scholes
 option-pricing model.

 Recent Accounting Pronouncements
 
 The Financial Accounting Standards Board ("FASB") recently issued Statement
 of Financial Accounting Standards No. 128 "Earnings Per Share" ("SFAS 128")
 and Statement of Financial Accounting Standards No. 129 "Disclosure of
 Information About an Entity's Capital Structure ("SFAS 129").  SFAS 128
 provides a different method of calculating earnings per share than is
 currently used in accordance with Accounting Board Opinion ("ABP") No. 15,
 "Earnings Per Share."  SFAS 128 provides for the calculation of "Basic" and
 "Diluted" earnings per share.  Basic earnings per share includes no
 dilution and is computed by dividing income available to common
 stockholders by the weighted average number of common shares outstanding
 for the period.  Diluted earnings per share reflects the potential dilution
 of securities that could share in the earnings of an entity, similar to
 fully diluted earnings per share.  SFAS 129 establishes standards for
 disclosing information about an entity's capital structure.  SFAS 128 and
 SFAS 129 are effective for financial statements issued for periods ending
 after December 15, 1997.  Their implementation is not expected to have a
 material effect on the consolidated financial statements.
 
 In June 1997, FASB issued Statement of Financial Accounting Standard No.
 130 "Reporting Comprehensive Income ("SFAS 130") and Statement of Financial
 Accounting Standard No. 131 "Disclosures about Segments of an Enterprise
 and Related Information ("SFAS" 131").  SFAS 130 establishes standard for
 reporting and display of comprehensive income, its components and
 accumulated balances. Comprehensive income is defined to include all
 changes in equity except those resulting from investments by owners and
 distributions to owners.  Among other disclosures, SFAS 130 requires that
 all items that are required to be recognized under current accounting
 standards as components of comprehensive income be reported in a financial
 statement that displays with the same prominence as other financial
 statements.  SFAS 131 supersedes Statement of Financial Accounting Standard
 No. 14 "Financial Reporting for Segments of a Business Enterprise."  SFAS
 131 establishes standards of the way the public companies report
 information about operating segments in annual financial statements and
 requires reporting of selected information about operating segments in
 interim financial statements issued to the public.  It also establishes
 standards for disclosures regarding products and services, geographic areas
 and major customers.  SFAS 131 defines operating segments as components of
 a company about which separate financial information is available that is
 evaluated regularly by the chief operating decision maker in deciding how
 to allocate resources and in assessing performance.
 
 SFAS 130 and SFAS 131 are effective for financial statements for periods
 beginning after December 15, 1997 and require comparative information for
 earlier years to be restated.  Because of the recent issuance of these
 standards, management has been unable to fully evaluate the impact, if any,
 the standards may have on future financial statement disclosures.  Results
 of operations and financial position, however, will be unaffected by the
 implementation of these standards.

 Notes to Consolidated Financial Statements
 
 
 1.  Going Concern
 
 The Company has a working capital deficit of $675,630 as of September 30,
 1997 and has incurred losses since its inception that raise substantial
 doubt about its ability to continue as a going concern.  In order to
 provide operating income, the Company plans to diversify into other fields. 
 In October 1996, the Company and ITN Energy Systems, Inc., a Colorado
 corporation, agreed to form a limited liability company called ITN/ES LLC
 to commercially exploit technologies developed and owned by ITN Energy
 Systems, Inc.  The technologies will be contributed to ITN/ES LLC by ITN
 Energy Systems, Inc., which will be the manager of ITN/ES LLC.  The
 technologies and products to be owned by ITN/ES LLC include production of
 thin-film electronic substrates by deposition upon which computer chips can
 be mounted; advanced processes for ceramic deposition on materials to
 improve their capacity to withstand heat and wear; and utilization of shape
 memory alloys that are highly advanced metals which by the proper
 application of heat, cold or electrical impulse can perform a mechanical
 function with precision for long periods of time.  The Company's ownership
 interest in ITN/ES LLC and all of its technologies is to be 10%, subject to
 the contribution of $200,000 in cash and 1,200,000 shares of Rentech
 restricted common stock. The agreement between ITN Energy Systems, Inc. and
 the Company recognizes that commercialization of the technologies already
 in existence as well as those that may be developed in the future by ITN/ES
 LLC may require establishment of additional business entities.  The
 Company, by mutual agreement, may provide additional capital to increase
 its ownership interest up and exceeding 50% of each technology in which it
 invests.  The Company will be entitled to distribution of revenues from
 ITN/ES LLC and the additional business entities in a percentage equal to
 its ownership interest.
 
 The Company is seeking sources of finance to provide for additional
 acquisitions and near term working capital.  The financing alternatives
 include private placements of its common stock or other equity interest in
 the Company, third-party loans and equity participation, or a combination
 of these methods.  The Company intends to exercise its right to convert
 convertible notes payable totaling $620,500 issued in September and October
 1997 into common shares at $.33 per share (see Notes 6 and 14). 
 Additionally, the Company has commitments from investment banking firms to
 raise funds for the purpose of eliminating all existing current and future
 debt as well as providing working capital for the start-up of the ITN/ES
 venture and the ITN/ES LLC.  A portion of the money raised will be used to
 further the Rentech Technology commercialization.  The Company believes
 this is sufficient to eliminate any future working capital requirements. 
 There are no assurances that any of these events will occur or that the
 Company's plan will be successful.  The accompanying financial statements
 do not include any adjustments that might result from the outcome of these
 uncertainties.

 2.  Business Acquisition
 
 On March 20, 1997, the Company acquired the assets of Okon for $1,050,000
 in cash, a $300,000 note due to the seller and $25,739 in acquisition
 costs.  The acquisition was recorded using the purchase method of
 accounting, by which the assets are valued at fair market value at the date
 of acquisition.  The operating results of this acquisition have been
 included in the accompanying consolidated financial statements from the
 date of acquisition.  The allocation of the purchase price was as follows:
 
 Inventories                                    $     83,977

 3.  Contracts
 
 During June 1994, the Company entered into a contract with a company
 incorporated in India to provide basic engineering design and consulting
 related to a plant to be constructed in India to use the Company's
 technology.  The work was completed during March 1995.  During February
 1996, the Company and Jamike Engineering Pty Ltd, entered into a second
 contract with the company incorporated in India to provide additional
 engineering design and consulting relating to a plant to be constructed in
 India to use the Company's technology for a gross contract price of
 approximately $223,000 ($281,600 in Australian dollars).  For the nine
 months ended September 30, 1996, the Company completed the contract and
 recognized contract revenue of $55,176 and incurred direct costs of
 $29,463.

 5.  Synhytech Project and Licensed Technology
 
 During 1992, Fuel Resources Development Company ("Fuelco"), a subsidiary of
 Public Service Company of Colorado ("PSCo"), completed construction of a
 full-scale conversion plant near Pueblo, Colorado.  The facility, called
 the Synhytech Project, cost approximately $25 million to construct,
 maintain and operate.  The purpose of the Synhytech Project was to build a
 plant that would use the Rentech Technology to convert landfill gas into
 liquid hydrocarbons.

 Rentech, Inc. and Subsidiary
 Notes to Consolidated Financial Statements
 
 The Company had an option to purchase and own up to a 15 percent interest
 in the Synhytech plant but, during 1991, the Company decided not to
 exercise its option to acquire the 15 percent interest in the Synhytech
 plant. 
 
 In April 1993, the Company and PSCo reached agreement on terms for transfer
 of the Synhytech plant to the Company, together with the separate catalyst
 manufacturing assets that Fuelco had assembled, and the related machinery
 and equipment.  The primary motivation for PSCo to enter into the transfer
 agreement was the Company's agreement to release all its claims that PSCo
 and Fuelco had failed to perform under its license agreement with the
 Company to construct a commercial sized plant that could be operated on a
 continuous basis. 
 
 In exchange for the resolution of all such claims, PSCo, Fuelco and
 Synhytech, Inc. had agreed, among other things, to transfer the Synhytech
 plant, catalyst plant, related equipment, other related assets and $650,000
 to the Company.  The Company also assumed equipment sublease obligations
 for various computer equipment, vehicles and other equipment used with the
 Synhytech plant.  In addition, the Asset Transfer Agreement provided that
 Fuelco's 20 percent interest in the Company's future revenue from royalties
 and licenses fees from future Rentech process plants reverted back to the
 Company. 
 
 As a result of the transfer of assets, the Company recorded a gain of
 approximately $1,286,000 on the conveyance of the Synhytech assets from
 Fuelco to the Company.  The gain was based upon the fair market value of
 determinable assets conveyed to the Company, including $650,000 in cash,
 less acquisition costs of approximately $205,000.  With the technological
 feasibility having been previously established, the Company converted and
 operated the plant for a three-week period in order to provide prospective
 licensees with verifiable statistics and evidence as well as allow
 observations and provide data on the use of the technology under operating
 conditions in full-size plant (the "demonstration run") and to evaluate the
 plant and its components for resale to one or more prospective licensees. 
 The Company's conversion of the plant commenced during early 1993, and its
 demonstration run was successfully completed during the summer of 1993.
 There were no problems relating to or in determining the technological
 feasibility of the Company's proprietary technology.  The cost of the
 demonstration run was approximately $3.4 million.  The Company expects to
 recover the capitalized expenditures from future license and royalty fees. 
 The plant was then shut down and remained idle.  The Company decided to
 sell the plant as a whole, except for the buildings, to its Indian licensee
 who dismantled the plant and shipped it to India to be used in a new plant
 under design for use of the Rentech Technology.  During 1995, the Company
 sold the plant for $223,620 and recorded a $244,880 loss from the sale.  As
 of September 30, 1997 and September 30, 1996, the Company has recorded a
 balance remaining of $99,500 in the Synhytech plant, which consists of the
 remaining buildings.  During the nine months ended September 30, 1996, the
 Company recorded a $100,000 write-down in the Synhytech plant held for
 sale.

 6.  Long-Term Debt
 
 During September 1997, the Company issued, for cash, convertible notes
 payable in the amount of $520,500 as part of a private offering through
 Neidiger/Tucker/Bruner, Inc. that closed in October 1997 (see Note 14). 
 During September 1997, the Company issued an additional convertible notes
 payable for $40,000.  Net proceeds from the private offering after paying
 commissions and offering costs were $481,554.  The convertible notes
 payable bear interest at 10% with interest payable at maturity.  The
 Company is to file a registration statement to register the shares of
 common stock acquired upon conversion of the convertible notes payable.  If
 the registration statement is not declared effective by the Securities and
 Exchange Commission within 90 days of the final closing, the interest rate
 of the convertible notes payable will be adjusted retroactively to 14% per
 annum.  The convertible notes payable are not collateralized and are due
 April 1998.  For each $1 received from the private offering, the Company
 issued one shares of its common stock.  As of September 30, 1997, the
 Company issued 560,500 of the Company's common stock valued at $170,645. 
 The Company recorded this amount as additional interest expense associated
 with these convertible notes payable.  The notes are convertible into
 shares of the Company's common stock at $.33 per share until April 16,
 1998.  If not converted by the noteholders by then, and if the Company does
 not pay the note in cash at that time, the noteholders may convert their
 notes to common stock at 70% of the average closing bid price for the five
 trading days prior to conversion not to exceed $.33 per share.  The balance
 in the convertible notes payable as of September 30, 1997 was $560,000. 
 
 On March 20, 1997, the Company entered into a $300,000 note payable with
 the sellers of Okon (see Note 2).  The $300,000 note payable accrues
 interest at 10% with monthly interest only payments due through March 1998. 
 Commencing March 15, 1998, monthly principal and interest are due through
 March 15, 1999.  The note is collateralized by all assets of Okon.
 
 
 During August 1997, the Company issued, for cash, notes payable in the
 amount of $390,000.  The notes bear interest at an annual interest rate of
 20%. These notes are due and payable on December 15, 1997 unless extended
 by the Company for an additional 60 days. If the notes are not paid at that
 time the principal amount and accumulated interest are due and payable,
 then interest will be paid on the total amount due at an annual rate of
 24%. As additional compensation, the noteholders were granted stock options
 to purchase 214,500 shares of the Company's common stock at a price equal
 to the market value on the date of grant (see Note 7).  The notes are
 collateralized by an assignment of the common stock of the Company's wholly
 owned subsidiary, Okon. An officer of the Company holds $90,000 of these
 notes payable.

 Preferred Stock
 
 During February 1997, the Company amended its articles of incorporation
 authorizing the issuance of 150,000 shares of series A preferred stock. 
 The holders of the series A preferred stock are entitled to receive, when,
 and if declared by the Board of Directors and out of funds legally
 available for the payment of dividends, dividends at the annual dividend
 rate of $1.50 per year on each outstanding share of preferred stock
 commencing upon issuance.  The dividends are payable quarterly in cash or
 at the option of the Company in shares of its free-trading common stock on
 the first day of April, July, October and January of each year commencing
 July 1, 1997.  The dividends shall accrue and become cumulative to the
 extent not declared and paid by the Company.
 
 The series A preferred stock are redeemable at the Company's election, in
 whole or in part, in cash equal to $12.50 per share plus any accumulated
 and unpaid dividends.  The Series A preferred stock and any accumulated and
 unpaid dividends are convertible at the option of the holder if not
 redeemable by the Company into common stock of the Company at the lesser of
 70% of the average of the closing bid price per share of the Company's
 common stock for the five trading days preceding the date of conversion or
 at 70% of the average of the closing bid price per share of the Company's
 common stock for the five trading days preceding the date of the stock
 subscription.
 
 During March 1997, the Company completed the $1,500,000 sale of 150,000
 shares of its series A preferred stock together with warrants to purchase,
 at approximately $.28 per share, additional shares of the Company's common
 stock.  The Company received net proceeds of $1,249,011 after deducting
 $250,989 in offering costs.  During April and May 1997, the preferred
 shareholders elected to convert $372,500 of their 37,250 shares plus
 dividends of $159,642 from the discount associated with the conversion
 feature of the series A preferred stock into 2,690,946 shares of the
 Company's common stock. The remaining shares were redeemed prior to
 September 30, 1997 at $12.50 per share plus accumulated dividends of
 $65,309 for a total cost of $1,474,684. As required by the terms of the
 preferred stock issue 3,423,456 warrants were issued upon the conversion

 The Company applies APB Opinion 25, "Accounting for Stock Issued to
 Employees", and related Interpretations accounting for the plans.  Under
 APB Opinion 25, because the exercise price of the Company's employee stock
 options equals the market price of the underlying stock on the date of
 grant, no compensation cost is recognized.
 
 FASB Statement 123, "Accounting for Stock-Based Compensation" ("SFAS No.
 123"), requires the Company to provide pro forma information regarding net
 loss and net loss per share as if compensation costs for the Company's
 stock option plans and other stock awards had been determined in accordance
 with the fair value based method prescribed in SFAS No. 123.  The Company
 estimates the fair value of each stock award at the grant date by using the
 Black-Scholes option-pricing model with the following weighted-average
 assumptions used for grants in 1997 and 1996, respectively: dividend yield
 of 0 percent for all years; expected volatility of 15 to 32 percent;
 risk-free interest rates of 5.40 and 5.52 percent; and expected lives of one 
 and five years for the Plans and stock awards.

 Under the accounting provisions for SFAS No. 123, the Company's net loss
 and net loss per share would have been increased by the pro forma amounts
 indicated below:

  8.  Commitments
  
  
  Employment Agreements
  
  The Company has entered into employment agreements that extend from March
  31, 1998 through December 31, 1999 with four of its officers.  The
  employment agreements set forth annual compensation to the four officers
  of between $112,000 and $114,000 each.  Compensation is adjusted annually
  based on the cost of living index. 
  
  
  Retirement Plans
  
  During 1990, the Company adopted a non-qualified profit sharing plan
  administered by a committee appointed by the Company's board of
  directors.  The profit sharing plan allows for current year bonuses of up
  to five percent of audited pre-tax earnings before depreciation,
  amortization and extraordinary income, if adjusted earnings for the
  preceding year exceeds $500,000.  No distributions have been granted
  since the inception of the plan.  Okon had a pre-existing qualified money
  purchase pension and profit sharing plan in place. The Company decided to
  continue with this plan for fiscal 1997.
  
  During 1985, Okon adopted a qualified money purchase pension and profit
  sharing plan administered by a committee appointed by Okon's board of
  directors for participants which include all employees age 18 and over
  who have been employed by Okon for two years.  The money purchase pension
  plan calls for Okon's contribution of 6% of each eligible participant's
  recognized compensation up to the integration level for the plan year and
  10.3% over the integration level for the plan year.  The profit sharing
  plan contributions are made at the discretion of Okon for eligible
  participants.  The combined money purchase pension and profit sharing
  contributions cannot exceed 25% of all eligible employees' wages, not to
  exceed $30,000 per participant.  For the period ended September 30, 1997,
  Okon contributed approximately $19,000 to the plans.
  
  
  Operating Leases
  
  The Company leases office space under a noncancelable lease which expires
  during November 1999, and the lease contains a renewal option for an
  additional five years.  The Company also leases office and warehouse
  space for its Okon operation, under a lease which expires during March
  1999.  The lease contains a renewal option for an additional three years. 
  In addition, provided that Okon is not in default under the lease, Okon
  has the option to purchase the facility at any time during the lease
  term.  Future minimum lease payments as of September 30, 1997 are as
  follows:

  Total lease expense for the year ended September 30, 1997 and for the
  nine months ended September 30, 1996 was approximately $53,000 and
  $39,000.
  
  As collateral for the Company's office lease, the Company had a $50,000
  letter of credit with a bank in favor of the landlord and provided a
  $50,000 certificate of deposit as of December 31, 1994 as collateral for
  the letter of credit.  The letter of credit and related collateral was
  reduced by one-half during 1995. The letter of credit matured on November
  30, 1996, and the certificate of deposit was returned to the Company.
  
  
  9.  Income Taxes
  
  There was no provision for income taxes required for the year ended
  September 30, 1997 and for the nine months ended September 30, 1996 due
  to operating losses in those years. 
  
  At September 30, 1997, the Company had available net operating loss
  carryforwards and capital loss carryforwards of approximately $7,000,000
  and $152,000 for tax reporting purposes.  The operating loss
  carryforwards expire through 2012, and the capital loss carryforward
  expires in 1999.  These carryforwards are subject to various limitations
  imposed by the rules and regulations of the Internal Revenue Service. 
  
  There were no tax credits established in the statements of operations
  since the Company has a 100 percent valuation allowance for the tax
  benefit of net deductible temporary differences and operating loss
  carryforwards.  Management is not able to determine if it is more likely
  than not that the deferred tax assets will be realized.  The Company has
  deferred tax assets with a 100 percent valuation allowance at September
  30, 1997 and September 30, 1996.  The tax effect on the components is as
  follows:

           (c)  The Company will execute and deliver to the Holder a new
 Warrant containing the same terms and conditions as this Warrant upon receipt
 by the Company of evidence reasonably satisfactory to it of the loss, theft,
 destruction, or mutilation of this Warrant, provided that  (i) in the case of
 loss, theft, or destruction, the Company receives from the Holder a reasonably
 
 
 
 
 <PAGE>
                                                       PAGE 69
   
 satisfactory indemnification, and  (ii) in the case of mutilation, the Holder
 presents and surrenders this Warrant to the Company for cancellation.  Any new
 Warrant executed and delivered shall constitute an additional contractual
 obligation on the part of the Company regardless of whether the Warrant that
 was lost, stolen, destroyed or mutilated shall be enforceable by anyone at any
 time.
 
      3.  Adjustments; Stock Dividends, Reclassification, Reorganization,
 Merger and Anti-Dilution Provisions.
 
           (a)  If the Company increases or decreases the number of its issued
 and outstanding Warrant Securities or changes in any way the rights and
 privileges of such Warrant Securities, by means of  (i) the payment of a
 dividend or the making of any other distribution on such Warrant Securities, 
 (ii) a forward or reverse split or other subdivision of Warrant Securities, 
 (iii) a consolidation or combination involving its Warrant Securities, or 
 (iv) a reclassification or recapitalization involving its Warrant Securities,
 then the Exercise Price in effect at the time of such action and the number of
 Warrant Securities purchasable pursuant to this Warrant at that time shall be
 proportionately adjusted so that the numbers, rights and privileges relating
 to the Warrant Securities then purchasable pursuant to this Warrant shall be
 increased, decreased or changed in like manner, for the same aggregate
 purchase price as set forth in this Warrant, as if the Warrant Securities
 purchasable pursuant to this Warrant immediately prior to the event at issue
 had been issued, outstanding, fully paid and nonassessable at the time of that
 event.
 
           (b)  If the Company pays or makes any distribution upon its Notes
 payable in securities or other property, excluding money but including
 (without limitation) shares of any class of the Company's stock or stock or
 other securities convertible into or exchangeable for shares of Common Stock
 or any other class of the Company's stock or other interests in the Company or
 its assets ("Convertible Securities"), a proportionate part of those
 securities or that other property shall be set aside by the Company and
 delivered to the Holder in the event that the Holder exercises this Warrant. 
 The securities and other property then deliverable to the Holder upon exercise
 of this Warrant shall be in the same ratio to the total securities and
 property set aside for the Holder as the number of Warrant Securities with
 respect to which the Warrant is then exercised is to the total Warrant
 Securities purchasable pursuant to this Warrant at the time the securities or
 property were set aside for the Holder.
 
           (c)  If at any time the Company grants to its shareholders rights to
 subscribe pro rata for additional securities of the Company, whether Common
 Stock, Convertible Securities, debentures, or other classifications, or for
 any other securities, property or interests that the Holder would have been
 entitled to subscribe for if, immediately prior to such grant, the Holder had
 exercised this Warrant, then the Company shall also grant to the Holder the
 same subscription rights that the Holder would be entitled to if the Holder
 had exercised this Warrant in full immediately prior to such grant.
 
           (d)  The Company shall cause effective provision to be made so that
 the Holder shall have the right after any event described below, by the
 exercise of this Warrant, to purchase for the aggregate Exercise Price
 described in this Warrant the kind and amount of shares of securities, and
 property and interests, as would be issued or payable with respect to or in
 exchange for the number of Warrant Securities of the Company that are then
 
 
 
 <PAGE>
                                                       PAGE 70
   
 purchasable pursuant to this Warrant as if such Warrant Securities had been
 issued to the Holder immediately before the occurrence of any of the following
 events:  (i) the reclassification, capital reorganization, or other similar
 change of outstanding securities of the Company, other than as described and
 provided for in subsection (a) above;  (ii) the merger or consolidation of the
 Company with one or more other corporations or other entities, other than a
 merger with a subsidiary or affiliate pursuant to which the Company is the
 continuing entity and the outstanding shares of Common Stock, including the
 Warrant Securities purchasable pursuant to this Warrant, are not converted or
 exchanged; or  (iii) the spin-off of assets to a subsidiary or an affiliated
 entity, or the sale, lease, or exchange of a signification portion of the
 Company's assets, in a transaction pursuant to which the Company's
 shareholders of record are to receive securities or other interests in another
 entity.  Any such provision made by the Company for adjustments with respect
 to this Warrant shall be as nearly equivalent to the adjustments otherwise
 provided for in this Warrant as is reasonably practicable.  The foregoing
 provisions of this subsection (d) shall similarly apply to successive
 reclassifications, capital reorganizations and similar changes of securities
 and to successive consolidations, mergers, spin-offs, sales, leases or
 exchanges.
 
           (e)  If any sale, lease or exchange of all, or substantially all, of
 the Company's assets or business or any dissolution, liquidation or winding up
 of the Company (a "Termination of Business") shall be proposed, the Company
 shall deliver written notice to the Holder or Holders of this Warrant in
 accordance with Section 4.  If the result of the Termination of Business is
 that shareholders of the Company are to receive securities or other interests
 of another entity, the provisions of subsection (d) above shall apply. 
 However, if the result of the Termination of Business is that shareholders of
 the Company are to receive money or property other than securities or other
 interests in another entity, the Holder or Holders of this Warrant shall be
 entitled to exercise this Warrant prior to the consummation of the event at
 issue and, with respect to any Warrant Securities so purchased, shall be
 entitled to all of the rights of the other Note holders with respect to any
 distribution by the Company in connection with the Termination of Business. 
 In the event no other entity is involved and subsection (d) does not apply,
 all purchase rights under this Warrant shall terminate at the close of
 business on the date as of which shareholders of record of the Common Stock
 shall be entitled to participate in a distribution of the assets of the
 Company in connection with the Termination of Business; provided, that in no
 event shall that date be less than 30 days after deliver to the Holder or
 Holders of this Warrant of the written notice described above and in Section
 4.  If the termination of purchase rights under this Warrant is to occur as a
 result of the event, a statement to that effect shall be included in that
 written notice.
 
           (f)  The provisions of this Section 3 shall apply to successive
 events that may occur from time to time but shall only apply to a particular
 event if it occurs prior to the expiration of this Warrant either by its terms
 or by its exercise in full.
 
      4.  Notice to Holders.  If, prior to the expiration of this Warrant
 either by its terms or by its exercise in full, any of the following shall
 occur:
 
                (i)  the Company shall declare a dividend or authorize any
      other distribution on its Notes or Common Stock; or
 
 
 
 <PAGE>
                                                       PAGE 71
   
                (ii)  the Company shall authorize the granting to the
      shareholders of its Common Stock or the holders of its Notes of rights
      to subscribe for or purchase any securities or any other similar
      rights; or
 
                (iii)  any reclassification, reorganization or similar change
      of the Common Stock, or any consolidation or merger to which the
      Company is a party, or the sale, lease, or exchange of any significant
      portion of the assets of the Company; or
 
                (iv)  the voluntary or involuntary dissolution, liquidation
      or winding up of the Company; or
 
                (v)  any purchase, retirement or redemption by the Company of
      its Notes or Common Stock; then, and in any such case, the Company shall
 deliver to the Holder or Holders written notice thereof at least 30 days prior
 to the earliest applicable date specified below with respect to which notice
 is to be given, which notice shall state the following:
 
                     (i)  the date on which a record is to be taken for the
                 purpose of such dividend, distribution or rights, or, if a
                 record is not to be taken, the date as of which the
                 shareholders of Common Stock or Note holders of record to be
                 entitled to such dividend, distribution or rights are to be
                 determined;
 
                     (ii)  the date on which such reclassification,
                 reorganization, consolidation, merger, sale, transfer,
                 dissolution, liquidation, winding up or purchase, retirement
                 or redemption is expected to become effective, and the date,
                 if any, as of which the Company's shareholders of Common
                 Stock of record shall be entitled to exchange their Common
                 Stock for securities or other property deliverable upon such
 
                 reclassification, reorganization, consolidation, merger,
                 sale, transfer, dissolution, liquidation, winding up,
                 purchase, retirement or redemption; and
 
                      (iii)  if any matters referred to in the foregoing
                 clauses (i) and (ii) are to be voted upon by shareholders of
                 Common Stock, the date as of which those shareholders to be
                 entitled to vote are to be determined.
 
      5.  Officers' Certificate.  Whenever the Exercise Price or the aggregate
 number of Warrant Securities purchasable pursuant to this Warrant shall be
 adjusted as required by the provisions of Section 3 above, the Company shall
 promptly file with its Secretary or an Assistant Secretary at its principal
 office, an officers' certificate executed by the Company's President and
 Secretary or Assistant Secretary, describing the adjustment and setting forth,
 in reasonable detail, the facts requiring such adjustment and the basis for
 and calculation of such adjustment in accordance with the provisions of this
 Warrant.  Each such officers' certificate shall be made available to the
 Holder or Holders of this Warrant for inspection at all reasonable times, and
 the Company, after each such adjustment, shall promptly deliver a copy of the
 officers' certificate relating to that adjustment to the Holder or Holders of
 this Warrant.

      6.  Reservation of Warrant Securities.  The Company hereby agrees that at
 all times prior to the Expiration Date it will have authorized and will
 reserve and keep available for issuance and delivery to the Holder that number
 of Warrant Securities that may be required from time to time for issuance and
 delivery upon the exercise of the then unexercised portion of this Warrant and
 all similar Warrants then outstanding and unexercised and upon the exercise of
 any Warrant Securities.
 
      7.  Registration Under the Securities Act of 1933.  The shares of Common
 Stock issuable upon exercise of this Warrant and the shares of Common Stock
 issuable upon conversion of the Note are subject to the Registration Rights
 Agreement in substantially the form of Exhibit B attached hereto and by this
 reference made a part hereof.
 
      8.  Transfer to Comply With the Securities Act of 1933.  
 
           (a)  This Warrant, the Warrant Securities, all securities underlying
 the Warrant Securities, and all other securities issued or issuable upon
 exercise of this Warrant, may not be offered, sold or transferred, in whole or
 in part, except in compliance with the Act, and except in compliance with all
 applicable state securities laws.
 
           (b)  The Company may cause substantially the following legend, or
 its equivalent, to be set forth on each certificate representing the Warrant
 Securities, securities underlying the Warrant Securities, or any other
 security issued or issuable upon exercise of this Warrant unless, in the
 opinion of legal counsel for the Company, such legend is not required:
 
                "The securities represented by this Certificate
                have not been registered under the Securities
                Act of 1933 (the  Act') and are  restricted
                securities' as that term is defined in Rule 144
                under the Act.  The securities may not be
                offered for sale, sold or otherwise transferred
                except pursuant to an effective registration
                statement under the Act or pursuant to an
                exemption from registration under the Act, the
                availability of which is to be established to the
                satisfaction of the Company."
 
           (c)  NOTWITHSTANDING ANYTHING HEREIN CONTAINED TO THE CONTRARY, THIS
 WARRANT SHALL NOT BE EXERCISABLE UNLESS AND UNTIL THE COMPANY IS SATISFIED
 THAT EXERCISE HEREOF WOULD NOT RESULT IN LOSS OF A CLAIMED SECURITIES
 REGISTRATION EXEMPTION IN CONNECTION WITH ANY OTHER ACTUAL OR PROPOSED
 TRANSACTION THE EFFECT OF WHICH WOULD BE MATERIALLY ADVERSE TO THE COMPANY.
 
      9.  Fractional Securities.  No fractional securities or scrip
 representing fractional shares shall be issued upon the exercise of all or any
 part of this Warrant.  With respect to any fraction of a security called for
 upon any exercise of this Warrant, the Company shall pay to the Holder an
 amount in money equal to that fraction multiplied by the current market value
 of that security.  The current market value shall be determined as follows:
 
 
 
 
 
 
 
 <PAGE>
                                                       PAGE 73
 
           (i)  if the security at issue is listed on a national securities
      exchange or admitted to unlisted trading privileges on such an exchange
      or quoted on the National Market System of the National Association of
      Securities Dealers Automated Quotation System, Inc. ("Nasdaq")
      quotation service, the current value shall be the last reported sale
      price of that security on such exchange or system on the last business
      day prior to the date of the applicable exercise of this Warrant or, if
      no such sale is made on such day, the average of the highest closing
      bid and lowest asked price for such day on such exchange or system; or
 
           (ii)  if the security at issue is not so listed or quoted or
      admitted to unlisted trading privileges, the current market value shall
      be the average of the last reported highest bid and lowest asked prices
      quoted on Nasdaq or, if not so quoted, then by the National Quotation
 
      Bureau, Inc. on the last business day prior to the date of the
      applicable exercise of this Warrant; or
 
           (iii)  if the security at issue is not so listed or quoted or
      admitted to unlisted trading privileges and bid and asked prices are
      not reported, the current market value shall be determined in such
      reasonable manner as may be prescribed from time to time by the Board
      of Directors of the Company.
 
      10.  Rights of the Holder.  The Holder shall not be entitled to any
 rights as a shareholder in the Company by reason of this Warrant, either at
 law or in equity, except as specifically provided for herein.  The Company
 covenants, however, that for so long as this Warrant is at least partially
 unexercised, it will furnish any Holder of this Warrant with copies of all
 reports and communications furnished to the shareholders of the Company.
 
      11.  Charges Due Upon Exercise.  The Company shall pay any and all issue
 or transfer taxes, including, but not limited to, all federal or state taxes,

 Warrant Securities that may be issued and delivered to a Holder of this
 Warrant upon the exercise of this Warrant and payment of the Exercise Price

 provided for in this Warrant shall be in writing and shall be personally
 delivered or deposited in the United States mail, postage prepaid, addressed
 to the respective party as indicated in the portions of this Warrant preceding
 Section 1.  All notices shall be deemed to be delivered upon personal delivery
 or upon the expiration of three business days following deposit in the United
 States mail, properly addressed and with postage prepaid.  The addresses of
 the parties may be changed, and addresses of other Holders and holders of
 Warrant Securities may be specified, by written notice delivered pursuant to
 this Section 13.  The Company's principal office shall be deemed to be the

 hereunder.
 
      15.  Miscellaneous Provisions.  
 
      Subject to the terms and conditions contained herein, this Warrant shall
 be binding on the Company and its successors and shall inure to the benefit of
 the original Holder, its successors  and assigns and all holders of Warrant
 Securities.  The exercise of this Warrant in full shall not terminate the
 provisions of this Warrant as it relates to holders of Warrant Securities.
 
      (a)  If the Company fails to perform any of its obligations hereunder, it
 shall be liable to the Holder for all damages, costs and expenses resulting
 from the failure, including, but not limited to, all reasonable attorney's

 condition waived in whole or in part except by an agreement in writing signed

      (c)  If any provision of this Warrant shall be held to be invalid,
 illegal or unenforceable, such provision shall be severed, enforced to the
 extent possible, or modified in such a way as to make it enforceable, and the
 invalidity, illegality or unenforceability shall not affect the remainder of
 this Warrant.
 
      (d)  The Company agrees to execute such further agreements, conveyances,
 certificates and other documents as may be reasonably requested by the Holder
 to effectuate the intent and provisions of this Warrant.
 
      (e)  Paragraph headings used in this Warrant are for convenience only and

         of the common stock, $.01 par value, of the Corporation (the "Common
         Stock")  (i) at any time prior to the Maturity Date at a conversion
         price of $0.33 per share of Common Stock, and  (ii) if the Note is
 
         not paid upon the Maturity Date, at any time during the
         180-day period following the Maturity Date, at a per-share
         conversion price of 70% of the average Closing Bid Price (as defined
         herein) of the Common Stock for the five trading days preceding the
         Conversion Date (as defined herein), but not more than $0.33 per
         share (the "Conversion Price").
 
     b.  Automatic Conversion.
 
         i.  If at any time during the 180-day period following the Maturity
         Date the average Closing Bid Price of the Common Stock for five
         consecutive trading days is $0.50 or more, then the principal amount
         of this Note shall automatically convert into shares of Common Stock
         at a price of $.033 per share.
 
         ii.  If this Note has not been converted or paid in full on or
         before ------------------, 1998 (360 days after the original date of
         issuance of this Note), then the principal amount of this Note shall
         automatically convert into shares of Common Stock at the
         per-share Conversion Price of 70% of the Closing Bid Price of the
         Common Stock for the five trading days preceding such date, but not
         more than $0.33 per share.
 
         iii.  The Conversion Date for these purposes shall be deemed to be
         the date on which automatic conversion of this Note occurred.
 
     c.  Termination of Conversion Right.  If the Corporation has called this
         Note for redemption, the right to convert shall terminate at the
         close of business on the second business day prior to the day fixed
         as the date for the redemption.
 
     d.  Conversion Date.  To convert this Note, the holder must surrender
         the same at the office of the Corporation, accompanied by a written
         notice of conversion and by a written instrument of transfer in a
         form satisfactory to the Corporation, properly completed and
         executed by the registered holder hereof or a duly authorized agent.

         proper form shall be referred to herein as the "Conversion Date."
         Subject to Section 10 hereof, on the Conversion Date  (i) this Note
         shall be deemed to have been canceled and paid in full,  (ii) the
         Corporation shall pay all interest accrued on this Note to the
         Conversion Date, and  (iii) the Holder shall be deemed to have all

     e.  Registration of Common Stock.  The Corporation covenants to file, to
         use its best efforts to cause to become effective and to maintain in
         effect for one year a registration statement under the Securities
         Act of 1933, as amended, and the laws of the states where the
   
         original holders of the Notes resided upon sale thereof, with
         respect to Common Stock issuable upon the conversion of the Note in
         accordance with the terms of the Registration Rights Agreement in
         the form of Exhibit A attached hereto and by this reference made a
         part hereof.  In the event the registration statement shall not have
         become effective within 120 days following the original date of
         issuance of this Note, then the interest rate payable with respect
         to the principal balance of this Note shall increase to 14% per
         annum.
     f.  Fractional shares.  No fractional shares or scrip representing
         fractional shares shall be issued upon the conversion of this Note. 
         With respect to any fraction of a share called for upon any
         conversion hereof, the Corporation shall pay to the Holder an amount
         in cash equal to such fraction multiplied by the Closing Bid Price
         of such fractional share, determined as follows:
 
         i.  If the Common Stock is listed on a national securities exchange
         or admitted to unlisted trading privileges on such exchange, the
         Closing Bid Price shall be the last reported sale price of the
         Common Stock on the composite tape of such exchange on the last
         trading day prior to the date of conversion of this Note or if no
         such sale is made on such day, the Closing Bid Price for such day on
         the composite tape of such exchange; or 
 
         ii.  If the Common Stock is not so listed or admitted to unlisted
         trading privileges, the Closing Bid Price shall be the mean of the
         last reported bid price reported by the Nasdaq Stock Market (or, if
         not so quoted on the Nasdaq Stock Market, on the OTC Bulletin Board
         or by the National Quotation Bureau, Inc.) on the last trading day
         prior to the date of the conversion of this Note; or
 
         iii.  If the Common Stock is not so listed or admitted to unlisted
         trading privileges and bid prices are not so reported, the Closing
         Bid Price shall be an amount, not less than book value, determined
         in such reasonable manner as may be prescribed by the Board of
         Directors of the Corporation, such determination to be final and
         binding on the Holder. 
 
      g. Adjustments to Conversion Price.
 
         i.  If the Corporation at any time pays to the holders of its Common
         Stock a dividend in Common Stock, the number of shares of Common
         Stock issuable upon the conversion of this Note shall be
         proportionally increased, effective at the close of business on the
         record date for determination of the holders of Common Stock
         entitled to the dividend.
 
         ii.  If the Corporation at any time subdivides or combines into a
         larger or smaller number of shares its outstanding shares of Common
         Stock, the number of shares of Common Stock issuable upon the
         conversion of this Note shall be proportionally increased in the
         case of a subdivision and decreased in the case of a combination,
         effective in either case at the close of business on the date that
         the subdivision or combination becomes effective.

         iii.  If the Corporation is recapitalized, consolidated with or
         merged into any other corporation, or sells or conveys to any other
         corporation all or substantially all of its property as an entity, 
         (a) the obligation of this Note shall remain in full force and
         effect, and  (b) provision shall be made as part of the terms of any
         such transaction so that the holder of this Note may receive, in
         lieu of the Common Stock otherwise issuable to him upon conversion
         hereof, the same kind and amount of securities or property as may be
         receivable or distributable upon the recapitalization,
         consolidation, merger, sale or conveyance with respect to the Common
         Stock into which this Note would have otherwise been convertible.
 
      4.  Subordination.  The rights of the holder of this Note to receive
 payment of any principal or interest hereon are subject and subordinate to the
 prior payment of the principal of (and premium, if any) and the interest on
 all other indebtedness of the Corporation incurred for money borrowed
 pursuant to promissory notes, debentures or other comparable evidences of
 indebtedness, whether now outstanding or subsequently incurred, whether
 secured or unsecured, and any deferrals, renewals or extensions of such
 indebtedness, or of any debentures, bonds or notes evidencing such
 indebtedness (the "Senior Indebtedness").  Senior Indebtedness shall not
 include the general obligations of the Corporation, including but not limited
 to its accounts payable, which are not incurred as a result of the borrowing
 of money.  In the event  (i) of any uncured or unwaived default in the payment
 of the principal and interest of Senior Indebtedness,  (ii) of any
 receivership, insolvency, assignment for the benefit of creditors, bankruptcy,
 reorganization, sale of all or substantially all of the assets, dissolution,
 liquidation or any other marshaling of the assets and liabilities of the
 Corporation, or  (iii) this Note is declared due and payable upon the
 occurrence of an Event of Default as defined in this Note, then no amount
 shall be paid by the Corporation with respect to principal and interest hereon
 unless and until the principal of and interest on all Senior Indebtedness then
 outstanding is paid in full.  Any amounts not paid hereon as a result of the
 provisions of this Section 4 shall be due and payable at such time as the
 restriction on such payment hereunder is no longer in effect and until
 payment, shall accrue interest as provided herein.
 
      5.  Redemption.  This Note may be redeemed in whole or in part at any
 time and from time-to-time during the 180-day period following the Maturity
 Date by the payment in good funds of the principal amount of this Note to be
 redeemed together with accrued interest on the amount redeemed to the date of
 redemption, at the office of the Corporation, upon the giving of the notice
 described below.  The Corporation shall not call this Note for redemption
 unless the requirements of Section 10 have been satisfied.  If the Corporation
 gives notice of redemption, the holder of this Note shall have the right for
 seven business days after the notice is given to convert the principal amount
 of the Note called for redemption, and accrued interest thereon, into Common
 Stock at a per-share conversion price of 70% of the Average Closing Bid Price
 of the Common Stock for the five trading days preceding the Conversion Date or
 $.33 per share, whichever is less.  This Note shall be deemed to have been
 canceled to the extent of the principal amount hereof redeemed upon payment of
 the redemption price or the setting aside of funds sufficient to pay the
 redemption price.
 
      6.  Covenants.  The Corporation shall not pay any dividend or make any
 other distribution on Common Stock except for distributions described in
 Section 3.g hereof.

          record shall be entitled to exchange their shares of Common Stock
          for securities or other property deliverable upon such
          reclassification, reorganization, consolidation, merger,
          conveyance, dissolution, liquidation or winding up.
 
      c.  Automatic Conversion.  Notice shall be mailed to the Holder
          regarding automatic conversion of this Note.  The Holder agrees
          promptly to deliver this Note to the office of the Company which,

          issuable upon such conversion in the name of the Holder.
 
      d.  Giving of Notice.  Any such notice shall be deemed to have been
          given or delivered upon deposit in the United States Mail, postage
          prepaid, addressed to the holder of the Note at his last address as
         it appears upon the records of the Corporation.

          whose name or names appear hereon as the absolute owner or owners
          of this Note for the purpose of receiving payment of, or on account
          of, the principal and interest due on this Note and for all other
          purposes, and it shall not be affected by any notice to the
          contrary.

      9.  Corporate obligation.  The holder of this Note shall not have any
          recourse for the payment in whole or of any part of the principal
          or interest on this Note against any incorporator or present or
          future stockholder, officer or Director of the Corporation.  The
          holder of this Note, by the acceptance hereof and as a part of the
          consideration for this Note, expressly agrees that the Note is the
          obligation solely of the Corporation and expressly releases all
          claims and waive all liability against the foregoing persons in
          connection with this Note.
 
      10. Transfer to Comply with the Securities Act of 1933.
 
          a.  Neither this Note nor the shares of Common Stock or any other
              security issued or issuable upon conversion of this Note may be
              offered or sold except in conformity with the Securities Act of
              1933, as amended, and then only against receipt of an agreement
              of such person to whom such offer of sale is made to comply
              with the provisions of this Section 10 with respect to any
              resale or other disposition of such securities.
 
          b.  The Corporation may cause the following legend to be set forth
              on each certificate representing the Common Stock or any other
              security issued or issuable upon conversion of this Note unless
              counsel for the Corporation is of the opinion as to any such
              certificate that such legend is unnecessary:  
                   The securities represented by this certificate
                   may not be offered for sale, sold or otherwise
                   transferred except pursuant to an effective
                   registration statement filed under the
                   Securities Act of 1933 (the "Act"), or pursuant
                   to an exemption from registration under the Act
                   the availability of which is to be established to
                   the satisfaction of the Corporation.  
 
         c.  NOTWITHSTANDING ANYTHING HEREIN CONTAINED TO THE CONTRARY, THIS
             NOTE SHALL NOT BE CONVERTIBLE INTO COMMON STOCK OR ANY OTHER
             SECURITY UNLESS AND UNTIL THE CORPORATION IS SATISFIED THAT
             CONVERSION HEREOF WOULD NOT RESULT IN LOSS OF A CLAIMED
             SECURITIES REGISTRATION EXEMPTION IN CONNECTION WITH ANY OTHER
             ACTUAL OR PROPOSED TRANSACTION THE EFFECT OF WHICH WOULD BE
             MATERIALLY ADVERSE TO THE CORPORATION.
 
      11.  Amendments and Waivers.
 
         a.  The Corporation may amend or supplement the Notes without notice
             to or the consent of the holders of the Notes  (i) to cure any
             ambiguity, omission, defect or inconsistency and  (ii) to make
             any other change that does not adversely affect the rights of
             the holders of the Notes.  The Corporation may similarly waive
             compliance with any provision of the Notes which waiver does not
             adversely affect the rights of the Note holders.
 
         b.  If it should ever be determined that the Notes were or are
             subject to provisions of the Trust Indenture Act of 1940, the
             Corporation may find it necessary or desirable to cause the
             Notes to be covered by a trust indenture administered by an
             independent trustee.  Accordingly, the Holders agree that the
             Corporation shall have the right and power to enter into a trust
 
 
 <PAGE>
                                                       PAGE 83
 
             indenture meeting the applicable requirements of the Trust
             Indenture Act of 1940, to appoint an independent trustee
             thereunder and, subject to Section 11.c herein, to make such
             modifications and amendments to the Notes as the board of
             directors of the Corporation, in the exercise of its discretion,
             shall deem necessary or desirable without any requirement for
             approval by the holders of the Notes.
 
         c.  The Corporation may otherwise amend the Notes only with the
             written consent of the holders of at least a majority of the
             principal amount of the Notes then outstanding; provided,
             however, that without the consent of the holder of each Note
             affected, no such amendment may  (i) reduce the rate or extend
             the time for payment of interest on the Notes,  (ii) reduce the
             principal of or extend the maturity of the Notes, or  (iii)
             reduce the required percentage for waiver or modification of the
             Notes.
 
         d.  Except as otherwise provided in Section 11.c above, the
             observance of any term or provision of this Note may be waived
             (either generally or in a particular instance and either
             retroactively or prospectively) and any default or event of
             default may be waived with the written consent of the
             Corporation and the Holders of at least a majority in principal
             amount of Notes then outstanding.
 
         e.  Except as otherwise provided in Section 11.c above, any
             amendment or waiver effected in accordance with this Section 11
             shall be binding upon each Holder of any Notes at the time
             outstanding, each future holder of all such Notes and the
             Corporation.  Each Holder acknowledges and agrees that by
             operation of this Section, the Holders of a majority in
             principal amount of Notes then outstanding will have the right
             and power to diminish or eliminate certain material rights of
             the Holder hereunder.
 
      12.  Miscellaneous.
 
         a.  The Corporation may consider and treat the person in whose name
             this Note shall be registered as the absolute owner thereof for
             all purposes whatsoever and the Corporation shall not be
             affected by any notice to the contrary.  This Note shall be
             registered as to both principal and interest on the books of the
             Corporation.  Subject to Section 10 herein, the transfer of the
             Note may be effected only by operation of law, accompanied by
             evidence satisfactory to the Corporation substantiating the
             transfer.  Communications sent to any registered holder shall be
             effective as against all holders or transferees of the Note not
             registered at the time of sending communication.
 
         b.  Payment of principal and interest shall be made to the
             registered owner of this Note upon presentation on or after the
             Maturity Date.  No interest shall be due on this Note for such
             period of time that may elapse between the maturity of this Note

                      FORM OF REGISTRATION RIGHTS AGREEMENT
 
 
                          REGISTRATION RIGHTS AGREEMENT
 
      THIS AGREEMENT is made and entered into this ------ day of -----------,
 1997, between RENTECH, INC., a Colorado corporation ("Company") and -------
 --------------------------------------------------------------------------
 ("Holder"). 
 
      In consideration of the mutual covenants contained herein, the parties
 agree as follows:
 
      1.  Definitions.  
 
          (a)  The term "Act" means the Securities Act of 1933, as amended;
 
          (b)  The terms "register," "registered," and "registration" refer to
 a registration effected by preparing and filing a registration statement in
 compliance with the Act and the declaration or ordering of effectiveness of
 such registration statement. 
 
          (c)  The term "Registrable Securities" means  (i) up to 1,666,667
 shares of Common Stock, par value $.01 per share, of the Company issuable or
 issued to those persons who purchase the Company's Ten Percent Convertible
 Subordinated Notes, together with 550,000 shares of Common Stock, plus 10%
 additional shares issuable as placement agent compensation, (collectively the
 "Holders"), and  (ii) any Common Stock of the Company issued as a dividend or
 other distribution with respect to, or in exchange or in replacement of, such
 Common Stock.
 
      2.  Request For Registration.  Within 30 days after the Holder and other
 Holders acquire the Company's Ten Percent Convertible Subordinated Notes that
 may be converted into at least 1,666,667 shares of the Registrable Securities
 and 550,000 shares of Common Stock, plus 10% additional shares issuable as
 placement agent compensation, and  (i) the Common Stock of the Company shall
 then be registered pursuant to Section 12(g) under the Securities Exchange Act
 of 1934 (the "1934 Act");  (ii) the Company is then current with all filing
 requirements under the 1934 Act; and  (iii) if the Company shall then qualify
 for use of a registration statement on Form S-3 covering all such Registrable
 Securities; then the Company except as otherwise provided below, shall use its
 best efforts to cause the registration under the Act of all Registrable
 Securities.  The Company shall be obligated to effect only one registration
 pursuant to this paragraph.  If the Company so elects, any request for
 registration under this paragraph may be for an underwritten public offering
 to be managed by an underwriter or underwriters of recognized standing
 reasonably acceptable to the Company.  Whenever required to use its best
 efforts to effect the registration of any Registrable Securities, the Company
 shall, as expeditiously as reasonably possible:
 
 
 
 
 
 
 <PAGE>
                                                       PAGE 86
   
          (a)  Prepare and file with the Securities and Exchange Commission a
 registration statement on Form S-3 with respect to such Registrable Securities
 and use its best efforts to cause such registration statement to become and
 remain effective; provided, however, that the Company shall in no event be
 obligated to cause any such registration to remain effective for more than the
 earlier of sale of all Registrable Securities covered thereby or one year
 after the date which the registration statement was declared or ordered
 effective. 
 
         (b)  Prepare and file with the SEC such amendments and supplements to
 such registration statement and the prospectus used in connection with such
 registration statement as may be necessary to comply with the provisions of
 the Act with respect to the disposition of all securities covered by such
 registration statement. 
 
          (c)  Furnish to the Holder such numbers of copies of a prospectus,
 including a preliminary prospectus, in conformity with the requirements of the
 Act, and such other documents as they may reasonably request in order to
 facilitate the disposition of Registrable Securities owned by them. 
 
          (d)  Use its best efforts to register and qualify the securities
 covered by such registration statement under the securities or blue sky laws
 of such other jurisdictions as shall be reasonably appropriate for the
 distribution of the securities covered by the registration statement, provided
 that the Company shall not be required in connection therewith or as a
 condition thereto to qualify to do business or to file a general consent to
 service of process in any such states or jurisdictions, and further provided
 that (anything in this Agreement to the contrary notwithstanding with respect
 to the bearing of expenses) if any jurisdiction in which the securities shall
 be qualified shall require that expenses incurred in connection with the
 qualification of the securities in that jurisdiction be borne by selling
 shareholders pro rata, the Holder shall pay such costs to the extent required
 by such jurisdiction. 
 
      3.  Furnish Information.  It shall be a condition precedent to the
 obligations of the Company to take any action that the Holder shall furnish to
 the Company such information regarding him or her, the Registrable Securities
 held by him or her, and the intended method of disposition of such securities
 as the Company shall reasonably request and as shall be required in connection
 with the action to be taken by the Company. 
 
      4.  Expenses of Registration.  All expenses incurred in connection with a
 registration pursuant to paragraph 2 (excluding underwriters' or securities
 broker-dealers' discounts, commissions and expenses), including, without
 limitation, all registration and qualification fees, printers' and accounting
 fees, and fees and disbursements of counsel for the Company, shall be borne by
 the Company. 
 
      5.  Delay of Registration.  Holder shall not have any right to take any
 action to restrain, enjoin, or otherwise delay any registration as the result
 of any controversy that might arise with respect to the interpretation or
 implementation of this Agreement. 
 
      6.   Indemnification.  If any Registrable Securities are included in a
 registration statement:
 
 
 
 
 
 <PAGE>
                                                       PAGE 87
   
           (a)  To the extent permitted by law, the Company will indemnify and
 hold harmless the Holder, any underwriter (as defined in the Act) for the
 Holder, and each such person, if any, who controls such Holder or underwriter
 within the meaning of the Act, against any losses, claims, damages, or
 liabilities, joint or several, to which they may become subject under the Act
 or otherwise, insofar as such losses, claims, damages, or liabilities (or
 actions in respect thereof) arise out of or are based on any untrue statement
 of any material fact contained in such registration statement, including any
 preliminary prospectus or final prospectus contained therein or any amendments
 or supplements thereto, or arise out of or based upon the omission or alleged
 omission to state therein a material fact required to be stated therein, or
 necessary to make the statements therein not misleading; and will reimburse
 the Holder, such underwriter, or controlling person for any legal or other
 expenses reasonably incurred by them in connection with investigating or
 defending any such loss, claim, damage, liability, or action; provided,
 however, that the indemnity agreement contained in this paragraph 6(a) shall
 not apply to amounts paid in settlement of any such loss, claim, damage,
 liability, or action if such settlement is effected without the consent of the
 Company (which consent shall not be unreasonably withheld) nor shall the
 Company be liable in any such case for any such loss, claim, damage, liability
 or action to the extent that it arises out of or is based upon an untrue
 statement or alleged untrue statement or omission or alleged omission made in
 connection with such registration statement, preliminary prospectus, final
 prospectus, or amendments or supplements thereto, in reliance upon and in
 conformity with information furnished expressly for use in connection with
 such registration by any such Holder, underwriter, or controlling person.
 
           (b)  To the extent permitted by law, the Holder will indemnify and
 hold harmless the Company, each of its directors, each of its officers who
 have signed the registration statement, each person, if any, who controls the
 Company within the meaning of the Act, and each agent and any underwriter for
 the Company (within the meaning of the Act) against any losses, claims,
 damages, or liabilities to which the Company or any such director, officer,
 controlling person, agent, or underwriter may become subject, under the Act or
 otherwise, insofar as such losses, claims, damages, or liabilities (or actions
 in respect thereto) arise out of or are based upon any untrue statement or
 alleged untrue statement of any material fact contained in such registration
 statement, including any preliminary prospectus or final prospectus contained
 therein or any amendments or supplements thereto, or arise out of or are based
 upon the omission or alleged omission to state therein a material fact
 required to be stated therein or necessary to make the statements therein not
 misleading, in each case to the extent, but only to the extend, that such
 untrue statement or alleged untrue statement or omission or alleged omission
 was made in such registration statement, preliminary or final prospectus, or
 amendments or supplements thereto, in reliance upon and in conformity with
 information furnished by the Holder expressly for use in connection with such
 registration; and the Holder will reimburse any legal or other expenses
 reasonably incurred by the Company or any such director, officer, controlling
 person, agent, or underwriter in connection with investigating or defending
 any such loss, claim, damage, liability, or action; provided, however, that
 the indemnity agreement contained in this paragraph 6(b) shall not apply to
 amounts paid in settlement of any such loss, claim, damage, liability, or
 action if such settlement is effected without the consent of the Holder (which
 consent shall not be unreasonably withheld).

           (c)  Promptly after receipt by an indemnified party under this
 paragraph of notice of the commencement of any action, such indemnified party
 will, if a claim in respect thereof is to be made against any indemnifying
 party under this paragraph, notify the indemnifying party in writing of the
 commencement thereof and the indemnifying party shall have the right to
 participate in, and, to the extent the indemnifying party so desires, jointly
 with any other indemnifying party similarly noticed, to assume the defense
 thereof with counsel mutually satisfactory to the parties.  The failure to
 notify an indemnifying party promptly of the commencement of any such action,
 if prejudicial to his ability to defend such action, shall relieve such
 indemnifying party of any liability to the indemnified party under this
 paragraph, but the omission to so notify the indemnifying party will not
 relieve him or any liability that he may have to any indemnified party
 otherwise than under this paragraph.
 
      7.  No Transfer of Registration Rights.  The registration rights of the
 Holder under this Agreement may not be transferred. 
 
     8.  Miscellaneous.  
 
           (a)  Entire Agreement.  This Agreement and the documents referred to
 herein constitute the entire agreement among the parties and no party shall be
 liable or bound by any other party in any manner by any warranties,
 representations, or covenants except as specifically set forth herein or
 therein.  The terms and conditions of this Agreement shall inure to the
 benefit of and be binding upon the respective successors and assigns of the
 parties.  Nothing in this Agreement, express or implied, is intended to confer
 upon any third party any rights, remedies obligations, or liabilities under or
 by reason of this Agreement, except as expressly provided in this Agreement. 
 
           (b)  Governing Law.  This Agreement shall be governed by and
 construed in accordance with the laws of the State of Colorado. 
 
           (c)  Counterparts.  This Agreement may be executed in two or more
 counterparts, each of which shall be deemed an original, but all of which
 together shall constitute one and the same instrument. 
 
           (d)  Titles and Subtitles.  The titles and subtitles used in this
 Agreement are used for convenience only and are not to be considered in
 construing or interpreting this Agreement. 
 
           (e)  Rights of Holders.  Each Holder shall have the absolute right
 to exercise or refrain from exercising any right or rights that such Holder
 may have by reason of this Agreement, including, without limitation, the right
 to consent to the waiver or any obligation of the Company under this Agreement
 and to enter into an agreement with the Company for the purpose of modifying
 this Agreement or any agreement effecting any such modification, and such
 Holder shall not incur any liability to any other Holder or Holders with
 respect to exercising or refraining from exercising any such right or rights.

           (f)  Time of Essence.  Time is of the essence regarding performance
