                                  The Company
    
  Colorado Greenhouse is the largest U.S.-based producer and marketer of high-
quality greenhouse tomatoes.  The Company's branded superpremium tomatoes are
characterized by their excellent flavor, rich red color and consistent blemish-
free appearance.  The Company currently operates six hydroponic (grown without
soil) greenhouses covering approximately 111 production acres in Colorado and
New Mexico and is constructing a seventh 20-acre hydroponic greenhouse in New
Mexico.  The Company plans to construct six additional 20-acre hydroponic
greenhouses over the next three years.  The Company's production sold was
approximately 247,000 pounds per acre for the six months ended June 30, 1998,
which represents an approximately 29% increase from the same period in 1996.
The Company also has increased its acreage by approximately 56% and increased
its net sales by approximately 77% over the same period.  In May 1998, the
Company acquired an approximately 25% equity interest in an affiliated group of
Mexican greenhouse companies ("Greenver") and obtained the exclusive right to
market in the United States, Canada and Europe all export-quality tomatoes from
Greenver's approximately 175 acres of non-hydroponic greenhouses in Mexico, half
of which are currently under construction and expected to be in production by
November 1998.  The Company anticipates that Greenver will provide it with up to
18 million pounds of tomatoes during Greenver's November 1998 through April 1999
growing season.     

  The Company's production and distribution capabilities enable it to provide
its customers with a consistent, year-round supply of superpremium branded
tomatoes.  The Company currently markets most of its tomatoes in ten states,
primarily to major supermarket chains, including Albertson's, Ingles, King
Soopers, Kroger, Lucky's, Meijer and Safeway, with the majority of sales
concentrated in California, Colorado, Michigan, North Carolina, Ohio, Tennessee
and Texas.  The Company recently completed an extensive market and consumer
study and, based upon its findings, plans to launch a marketing campaign for its
newly developed consumer brand in September 1998, emphasizing the consistent
year-round quality and superior taste of its tomatoes.  A key component of the
Company's growth strategy is to market its tomatoes in selected new domestic
markets and establish relationships with additional major supermarket chains.

  Industry sources estimate that greenhouse tomatoes accounted for only
approximately 8% of the approximately 5.4 billion pound ($1.8 billion) U.S.
fresh tomato market in 1997.  Historically, U.S. fresh tomato consumption has
decreased dramatically during the winter months due to the lack of a consistent
supply of quality tomatoes.  There is substantial year-round consumer demand,
however, for higher quality, fresh, superpremium food products, including
tomatoes. Accordingly, industry sources estimate that greenhouse tomatoes' share
of the U.S. fresh tomato market will increase significantly over the next five
years.  The Company believes that its ability to offer a consistent, high-
quality superpremium tomato on a year-round basis and its greenhouse expansion
plans will permit it to lead this growth opportunity.

Company Strengths

  The Company's key competitive strengths include:

  .       Consistent Quality Superpremium Tomatoes on a Year-Round Basis. The
          Company has established a reputation as a consistent supplier of high
          quality, branded superpremium tomatoes. The Company's greenhouse
          locations in Colorado and New Mexico are characterized by an optimal
          combination of direct sunlight and moderate summertime temperatures,
          which provide it with the ability to grow high-quality tomatoes on a
          year-round basis.  Commencing in November 1998, the Company will begin
          marketing Greenver's tomatoes.  This

                                       3
<PAGE>
 
          will provide the Company with a greater supply of tomatoes from
          November through April, when domestic supply is generally at its
          lowest and prices are typically at their highest.

  .       Direct Relationships with Major Supermarket Chains.   The Company
          sells directly to several of the nation's largest supermarket chains,
          including  Albertson's, Ingles, King Soopers, Kroger, Lucky's, Meijer
          and Safeway. These direct relationships enable the Company to: (i)
          retain control over the distribution process; (ii) establish a "non-
          commodity" consumer branding approach to marketing; (iii)
          differentiate itself through superior customer service; and (iv)
          improve margins by eliminating unnecessary middlemen.

  .       Technical Expertise.  The Company's advanced growing techniques
          enable it to produce consistently high-quality tomatoes on a year-
          round basis.  The Company's greenhouses are managed by teams of senior
          growers, principally recruited from European countries, with expertise
          in the latest greenhouse and hydroponic technology.  These senior
          growers train junior growers to assure that the Company will have the
          expertise necessary for its planned expansion.  Forty of the Company's
          production acres have been constructed, and 20 acres are being
          constructed, using a state-of-the-art model designed to enhance
          growing conditions and  improve production yield.  The Company also
          has installed an integrated management information system, which
          allows it to monitor closely all aspects of the plant production,
          packaging and selling process.

Growth Strategy

  The Company's objective is to strengthen its position as the largest U.S.-
based producer and marketer of high quality greenhouse tomatoes and to increase
sales.  Key elements of the Company's strategy to achieve this goal include:

  .       Aggressively Develop Consumer Brand Identity.  To capitalize on the
          regional success of the Company's branding strategy, in September
          1998, the Company plans to introduce a marketing campaign targeting
          additional domestic markets with its newly developed consumer brand.
          This campaign will include both trade and consumer advertising and
          point-of-sale promotions emphasizing the consistent year-round
          availability and superior taste of the Company's tomatoes.  The
          Company believes that its branding strategy also may facilitate its
          future introduction of other superpremium greenhouse produce.

  .       Expand Production Capacity. The Company's strategy is to expand
          production capacity to meet the increased consumer demand for
          consistent, high-quality tomatoes on a year-round basis. The Company
          is currently constructing a 20-acre hydroponic greenhouse facility in
          New Mexico and plans to construct six additional 20-acre hydroponic
          greenhouses over the next three years at sites that provide optimal
          micro-climatic conditions of sunlight and temperature.  The Greenver
          marketing arrangement will provide the Company with a greater supply
          of tomatoes from November through April, when domestic supply is
          generally at its lowest and prices are typically at their highest.

  .       Broaden Retail Distribution.  Most major retailers seek a primary
          supplier for each produce category that is capable of delivering both
          uniform quality and consistent year-round supply.  The Company
          believes that by offering retailers and consumers a high quality
          product with a consistent year-round supply, it can become the primary
          year-round tomato supplier of choice for many major supermarket
          chains.  The Company's variety of product sizes and grades and
          customized packaging capabilities also provide significant flexibility
          to retail chains when offering tomato products to consumers.  The
          Company's expertise in conducting marketing programs can assist these
          retailers in developing consumer awareness and brand loyalty.

                    Company History and Recent Developments

  Organizational History.  The Company's business arose from the need for
developers of cogeneration electric power plants to obtain secondary users
("heat hosts") of heat generated by the power plants.  In the 1980's, the
developers of four Colorado cogeneration plants (two in Brush and one each in
Fort Lupton and Rifle) selected greenhouses as heat hosts because Colorado's
micro-climatic conditions are favorable to greenhouse production.  Tomatoes were
chosen as the crop for these greenhouses based on their revenue producing
potential.  Prior to January 1,1994, the greenhouses at 

                                       4
<PAGE>
 
the Brush #1, Brush #2 and Fort Lupton #1 power plants were operated separately
under the supervision of a common management committee. On January 1, 1994, the
Company's predecessor, Colorado Greenhouse, LLC (the "LLC"), began to operate
the Brush #1, Brush #2 and Fort Lupton #1 greenhouses, and Rifle was added on
January 1, 1996. Integrating these operations allowed the Company to market more
efficiently its products, reduce production costs and coordinate growing
schedules. Construction of the Estancia and Fort Lupton #2 greenhouses was
completed by the Company in August 1997 and January 1998, respectively. The
Estancia and Fort Lupton #2 greenhouses are not part of a cogeneration project.
    
  1997 Production Problems.  During 1997, the Company experienced mechanical
problems, pest and disease infestations and a flood that significantly reduced
production during parts of the year in three of the Company's greenhouses.  In
the Brush #1 greenhouse, a root disease reduced tomato production by
approximately 18.9% during the first and second quarters of 1997.  This was
followed in the third quarter by an invasion of thrips (an insect) through the
greenhouse's unscreened ventilation system, which carried a virus from adjacent
agricultural field crops.  This virus reduced plant populations as well as
tomato volumes and size, resulting in a decline in the Company's average sales
price per pound.  During the third quarter of 1997, Brush #2 was also affected
negatively by the same root disease that affected Brush #1 and was infested with
a large population of whiteflies.  This led to the Company's decision to pull
out its entire existing crop at Brush #2 and disinfect the greenhouse at the
beginning of the fourth quarter of 1997.  At the end of the first quarter of
1997, the Fort Lupton #1 greenhouse experienced a mechanical failure in its
irrigation system, followed by a flood at the end of July that required the
Company to pull out the entire crop to avoid an outbreak of root rot common in
water damaged crops.  As a result of all of these problems, the Company
experienced approximately a 13% decline in total production sold in 1997
compared to 1996, despite the addition of production from the 20-acre Estancia
greenhouse in October 1997.  The Company believes it has remedied the problems
that lead to mechanical malfunctions and has used the experiences to update its
existing greenhouses and better design future greenhouses.  The Company hired a
new senior management team that has implemented various initiatives and quality
control measures to reduce the likelihood of similar problems occurring in the
future and obtained improved insurance coverage.  See "Risk Factors--Risk of
Loss to Crop from Pests or Mechanical Failures" and "Business--Greenhouse
Production--Quality Control Programs."     
    
  1998 Weather Event.  In May 1998, the Company's Brush #1 and Brush #2
greenhouses were damaged by a hail storm coupled with severe winds.  The Brush
#2 greenhouse suffered significant damage to its glass and related crop as a
result of the hail, and the Company decided to pull out the entire crop.  The
hail also punctured some of the plastic at the Brush #1 greenhouse although most
of the crop in Brush #1 was salvaged.  As a result of the hail storm, the
Company expects to lose a total of approximately $4.5 million in net sales
during the second and third quarters of 1998.  For the six months ended June 30,
1998, the Company has recorded a receivable for an insurance advance of $2.0
million related to property and business interruption coverage, of which $1.6
million has been recognized on the Company's statement of operations, offset by
the recognition of a $1.7 million loss from hail damage, resulting in a $0.1
million charge to operations.  The Company has filed insurance claims for
property and business interruption damages incurred in the hail storm totaling
$3.1 million less deductibles of $50,000.  With the processing of these claims,
additional proceeds may be available subject to the final determination of the
insurance company.  See "Risk Factors--Risk of Catastrophic Loss of Crop and
Property Damage."     
    
  Greenver Transaction.  In May 1998, the Company acquired a 25% equity interest
in Greenver for $4.0 million (the "Greenver Transaction").  Greenver has 88
acres of non-hydroponic greenhouses under production in Baja, Mexico, which
produce tomatoes and some sweet peppers.  The proceeds of the Company's
investment in Greenver are being used by Greenver to construct an additional 87
acres of non-hydroponic greenhouse facilities, which are expected to be in
production by November 1998.  As part of the Greenver Transaction, the Company
obtained the exclusive right to market in the United States, Canada and Europe
all export-quality tomatoes produced by Greenver, for which the Company will
receive a 10% commission.  The Company estimates that the Greenver Transaction
will provide it with up to 18 million pounds of tomatoes during Greenver's
November 1998 through April 1999 growing season, the time of year when domestic
supply is generally at its lowest and prices are typically at their highest.
Although Greenver's tomatoes are of comparable quality to the Company's
tomatoes, the Company will provide Greenver with technical assistance to
increase Greenver's production yield and the Company intends to introduce
hydroponic growing techniques to at least some of Greenver's facilities.  As a
result of its equity interest, the Company is entitled to 25% of all dividends,
if any, distributed by Greenver.

  May 1998 Private Placement.  In May 1998, the Company completed the sale of
$6.0 million of its Series C Convertible Preferred Stock at $5.50 per share.
The proceeds were used to fund the Greenver Transaction and a portion of the
construction costs of the Company's new greenhouse in Grants, New Mexico.  The
Series C Convertible Preferred Stock was offered by the Company in two tranches
solely to its existing preferred stockholders or their related parties on a pro
rata basis.  The Company entered into a Registration Rights Agreement with the
Series C Convertible Preferred Stock purchasers, whereby the Company agreed to
register the Common Stock issued upon conversion of the Series C Convertible
Preferred Stock in certain circumstances, at the Company's expense.  See
"Certain Transactions and Relationships--Sale of Series C Convertible Preferred
Stock" and "Description of Capital Stock--Registration Rights." Upon the closing
of this offering, the Series C Convertible Preferred Stock will be converted
into Common Stock on a one share for one share basis.

- -------------------
(1) The Company was organized in 1993 to operate three greenhouses and incurred
    marketing expenses in anticipation of these operations.  Effective January
    1, 1994, the Company began to operate three greenhouses (Brush #1, Brush #2
    and Fort Lupton #1).  Effective January 1, 1996, the Company  began to
    operate a fourth greenhouse (Rifle).  In October 1997, the Company began
    production from its fifth greenhouse (Estancia), and in March 1998, the
    Company began production from its sixth greenhouse (Fort Lupton #2).
    
(2) Operating expenses for 1997 have been reduced to reflect insurance proceeds
    of $802,000 from the flood in July 1997 at Fort Lupton #1.  Operating
    expenses for the six months ended June 30, 1998, include a loss of
    $1,700,000 resulting from the hail storm in May 1998 at Brush #1 and Brush
    #2 and have been reduced to reflect insurance proceeds of $1,608,000.

(3) Prior to January 1997, the Company was operated as a limited liability
    company and was not subject to federal or state income taxes.  As a result,
    the provision (benefit) for  income taxes and net income (loss) for the
    years 1993 to 1996 are presented on a pro forma basis as if the Company were
    subject to federal and state corporate income taxes, assuming an effective
    tax rate of 38%.  See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations--Introduction."
    
(4) Average yield sold per acre on an annual basis is calculated by dividing the
    total number of pounds sold by the total number of acres in production.
    Average yield sold per acre for 1997 is a weighted average of 76 acres based
    on the increase of total acres in production during the year as a result of
    the Estancia greenhouse, which began production in October 1997.  Management
    believes that average yield per acre sold is an important measure of
    greenhouse productivity.     
    
(5) Adjusted to give effect to the sale of the 3,500,000 shares of Common Stock
    offered by the Company hereby (at an assumed initial public offering price

    outstanding indebtedness, the cashless exercise of a warrant to purchase
    9,743 shares of Series B Convertible Preferred Stock (at an assumed initial

                                  RISK FACTORS

  The Common Stock offered hereby involves a high degree of risk.  Prospective
investors should consider carefully, in addition to the other information set
forth in this Prospectus, the following risk factors before purchasing the
shares of Common Stock offered hereby.

Limited Operating History

  Prior to 1994, the greenhouses at the Brush #1, Brush #2, and Fort Lupton #1
sites were operated separately under the supervision of a common management
committee.  On January 1, 1994, the Company began to operate the Brush #1, Brush
#2 and Fort Lupton #1 greenhouses, and Rifle was added on January 1, 1996.  Two
additional greenhouses were constructed by the Company in August 1997 and
January 1998, respectively.  Accordingly, the Company has only a limited
operating history upon which prospective investors can evaluate the Company's
business and prospects.

Risk of Catastrophic Loss of Crop and Property Damage

  As in any agricultural business, there is an unquantifiable risk of a weather-
related catastrophe that causes substantial damage to, or total failure of, the
Company's or Greenver's crop at one or more greenhouses and severely damages or
destroys the greenhouse or greenhouses.  Potential catastrophes include floods,
tornadoes, hail storms, severe wind and rain or in the case of Greenver,
hurricanes.  The Company's greenhouses in Brush and Fort Lupton, Colorado are
located in areas that have a high frequency of severe weather, particularly hail
storms and tornadoes.  The Fort Lupton #1 greenhouse crop was destroyed by a
flash flood in July 1997.  The Brush #1 and #2 greenhouses were damaged by a
hail storm in May 1998.  This forced the Company to pull out the entire crop
from the Brush #2 greenhouse, and although much of the crop in the Brush #1
greenhouse has been salvaged, there was some damage to the crop that may result
in a decrease in production.  It is likely that one or more of the Company's
greenhouses and crops will suffer damage from weather in the future.  Because
the Company currently operates only a few greenhouses, any damage to a
greenhouse and resulting  lost tomato production is likely to have a greater
adverse effect on the Company's production and results of operations than if the
Company operated more greenhouses.  Furthermore, the Company has two greenhouses
each in Brush and Fort Lupton, which increases the likelihood that a weather-
related catastrophe in either of these two locations will more adversely affect
the Company than if its greenhouses were more geographically dispersed.  See
"Business--Facilities."
    
  The Company has obtained insurance intended to cover property damage, crop
loss and consequential losses (such as lost profits) caused by weather events.
The Company cannot predict, however, whether this insurance coverage will be
sufficient to cover all of the Company's weather-related losses.  The Company's
insurance coverage in 1997 was not sufficient to cover all of its losses from
the flood at the Fort Lupton #1 greenhouse and, as a result, the Company
obtained new insurance policies in December 1997, which are intended to provide
better coverage for consequential losses.  The Company has filed claims for
damages sustained during the May 1998 hail storm at its facilities in Brush and
although no final determination on these claims has been made by the Company's
insurance carrier, to date, the Company has received a $2.0 million advance on
these claims.  Under the terms of its current insurance coverage, for business
interruption and property damage the Company's policy limits of $33.0 million
are limited to $5.0 million per occurrence. The Company cannot predict whether
it will be able to obtain adequate insurance coverage in the future at
acceptable premium costs and deductible amounts.  See "Business--Risk
Management; Insurance; Legal Proceedings."     

Risk of Loss to Crop from Pests or Mechanical Failures
    
  Plant diseases, such as root rot, or pest infestations, such as whiteflies,
can destroy all or a significant portion of the Company's or Greenver's tomato
plants in a greenhouse and could eliminate or significantly reduce production
from that greenhouse until the Company or Greenver is able to disinfect the
greenhouse and grow replacement tomato plants.  The Company does not carry
insurance for crop damage from disease or pest infestations and does not believe
it can obtain this type of coverage.  See "Business--Risk Management; Insurance;
Legal Proceedings."  The Company has experienced crop disease and pest
infestations in the past.     

  In 1997, the Company experienced root disease originating from soil-born
contaminants in the Company's nursery operations in its Brush #1 greenhouse,
which resulted in an approximately 18.9% reduction in that greenhouse's tomato

                                       10
<PAGE>
 
production over the first and second quarters of 1997. This was followed in the
third quarter by an invasion of thrips (an insect) through the greenhouse's
unscreened ventilation system, which carried a virus from adjacent agricultural
field crops.  This virus reduced plant populations as well as tomato volumes and
size, resulting in a decline in the Company's average sales price per pound.
During the third quarter of 1997, Brush #2 was also affected negatively by the
same root disease that affected Brush #1 and was infested with a large
population of whiteflies.  This led to the Company's decision to pull out its
entire existing crop at Brush #2 and disinfect the greenhouse at the beginning
of the fourth quarter of 1997. Also during 1997, the Company's Fort Lupton #1
greenhouse experienced a mechanical failure in its irrigation system in the
first quarter, which, in conjunction with the flood experienced in July 1997,
destroyed a portion of the tomato crop in the greenhouse.  The Company's
management decided to pull out the entire crop to avoid an outbreak of root rot
common in water damaged crops.  There can be no assurance that the Company or
Greenver will not suffer loss to its tomato crop at one or more of its
greenhouses as a result of disease, pest infestation or mechanical failures.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Greenhouse Production--Steps Taken to Combat 1997
Production Problems."

Construction Risks

  The Company plans to construct six new hydroponic greenhouse facilities over
the next three years in addition to the 20-acre facility in Grants, New Mexico
currently under construction.  Construction of greenhouses requires skilled
construction personnel.  There can be no assurance that the Company will be able
to locate the required personnel or that construction of the greenhouses will be
completed within the Company's anticipated time frame or budget.  Construction
projects are subject to cost overruns and delays not within the control of the
Company or its subcontractors, such as those caused by acts of governmental
entities, financing delays or bad weather.  Delays can also arise from design
changes and material equipment shortages or delays in delivery.  The Company's
inability to construct the Grants, New Mexico greenhouse or any future
greenhouse in a timely fashion and within the projected construction budget
could have a material adverse effect on the Company's anticipated financial
performance.  See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources."

Perishable Crop

  The Company's and Greenver's tomatoes are subject to all the risks of any
perishable food, including spoilage. Tomatoes generally are salable for
approximately 10 to 14 days after harvesting.  The Company and Greenver must
transport many of its tomatoes long distances from its greenhouses to its pack
houses and then to its customers from its pack houses or its cross-docking
facility near San Diego (used for Greenver's tomatoes).  Accordingly, any delay
in shipment of the Company's or Greenver's tomatoes could result in the loss of
the shipment due to spoilage. See "Business--Customers and Product
Distribution."

Inherent Seasonality in Supply of Tomatoes
    
  The Company's business is seasonal, and its quarterly results of operations
reflect trends resulting from seasonal variations in production yields and
prevailing prices for tomatoes.  Price fluctuations and tomato availability have
a direct effect on the Company's financial results.  Typically, in the winter
months, the reduced supply of tomatoes (due primarily to the lack of field-grown
tomatoes) results in higher market prices.  Through the spring and summer
months, the supply of field-grown tomatoes increases, resulting in lower market
prices.  As a result, the Company historically has experienced lower total
revenues but higher profit margins in the first and second quarters.  Although
the Company's production in the first quarter is lower due to fewer hours of
direct sunlight, prevailing prices are higher, and in the second quarter, the
Company's production increases although prevailing prices are lower.
Thereafter, although revenues increase, profits typically have declined in the
third quarter as the Company experiences planned decreases in production to
coincide with expected lower market price periods.  In the fourth quarter,
revenues increase and profits typically have increased also as the Company's
production remains steady but higher market prices return.  Greenver produces
tomatoes in its Mexican greenhouses only from November through May.  As a result
of the Greenver marketing agreement commencing in the fall of 1998, the
Company's supply of tomatoes during these months should increase significantly
from 1997 and prior years' supplies during the same months.  Accordingly, the
Company expects that its revenues and profitability will continue to be subject
to large seasonal variations, and the Company's results of operations for any
particular quarter are not expected to be indicative of results for subsequent
quarters or the full year. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Seasonality; Quarterly Results."
     

                                       11
<PAGE>
 
    
Lack of Control over Tomato Prices and Fixed Operating Costs     

  The Company's profitability is dependent upon the price at which it is able to
sell its and Greenver's tomatoes.  The Company has virtually no control over the
price at which it is able to sell tomatoes because tomato prices move in
response to market supply.  The greater supply of tomatoes in the summer months
as a result of the harvesting of field-grown tomatoes pushes prices downward.
Conversely, the reduced supply of tomatoes in the winter months pushes tomato
prices upward.  To the extent prevailing market prices for tomatoes are lower
than anticipated by the Company, the Company's profitability will be negatively
affected.  Variations in the Company's production of tomatoes also will have a
significant effect on the Company's profitability due to the fact that many of
the Company's operating costs are fixed.  See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Seasonality;
Quarterly Results."

Dependence on Sufficient Water and Heat for Crops

  The Company's crops must be irrigated regularly to maintain plant growth and
optimal tomato production.  The Company obtains water for irrigation for each of
its greenhouses either from one or more wells or the municipal water supply and
has only limited ability to store and recirculate water for its irrigation
systems.  As a result, any interruption in the water supply lasting longer than
a few days to a particular greenhouse is likely to result in a decline in the
Company's tomato production at that greenhouse.  The Company experienced a
mechanical failure in the irrigation system at one of its greenhouses in 1997
and could experience another failure in the future, which, if not quickly
repaired, also could result in a decrease in tomato production.  During the
colder months, the Company's greenhouses must be heated to maintain adequate
temperature levels to protect the tomato plants.  The Company normally heats
four of its greenhouses with hot water from neighboring electric cogeneration
facilities.  The Company also has backup boilers at each facility.  The
cogeneration facilities' inability to provide the greenhouses with adequate hot
water, whether as a result of an event within or beyond the cogeneration
facilities' control, coupled with a failure of the greenhouse's backup heating
system, also is likely to result in a decrease in the Company's tomato
production.  See "Business--Greenhouse Production."

Availability of Labor

  The maintenance of the Company's tomato crops and harvesting of tomatoes is
labor intensive.  Industry participants, including the Company, experience high
turnover rates among hourly workers.  Some of the Company's employees do not
work 40 hour weeks or leave the Company's employment without notice, forcing the
Company to hire and train additional employees to maintain and harvest its
tomato plants.  To the extent the Company experiences higher turnover rates, it
will encounter higher than expected recruiting, training and other employment
costs.  Immigrants comprise a large portion of the Company's workforce.  Any
change to existing U.S. immigration policy that restricts the ability of
immigrant workers to obtain employment in the United States is likely to
contribute to a shortage of available labor and increase the Company's operating
costs.  Immigration laws require the Company to confirm the legal status of its
immigrant labor force.  From time to time, the Company may unknowingly employ
illegal immigrants.  The Company, as a significant employer of immigrant
laborers, is subject to periodic, random searches by the Immigration and
Naturalization Service ("INS").  If the INS finds illegally employed immigrants,
the Company would suffer the loss of a portion of its labor force and could be
subject to fines, some of which could be substantial in amount.  See "Business--
Employees and Training" and "Business--Government Regulation."

Sensitivity to Price Increases in Raw Materials

  In 1997, raw material costs accounted for approximately 27.4% of the Company's
cost of goods sold.  Increases in the cost of raw materials essential to the
Company's operations, particularly tomato plant seedlings, bees, rockwool,
carbon dioxide, fertilizer, insecticides and packaging materials, would increase
the Company's costs of production, which the Company may be unable to recoup
through higher prices for its tomatoes.  A scarcity of these raw materials could
require the Company to curtail production, which also would have a material
adverse effect on the Company's results of operations.  The Company generally
does not enter into agreements for the supply of any raw materials for longer
than one year.  The Company currently obtains its tomato plant seedlings from a
single source.  Loss of this source could result in a decrease in the Company's
tomato production during the time in which this supplier is being replaced.  See
"Business--Greenhouse Production--Raw Materials Used in Production."

                                       12

Risks Related to Greenver Investment; Risks Inherent in Foreign Investment

  The Company has invested $4.0 million in Greenver.  The Company's strategy is
to use production from Greenver's facilities to offer a more consistent supply
of tomatoes for the Company's U.S. customers from November through April. The
Company anticipates that approximately one-third of its winter production will
come from Greenver's facilities. Greenver's failure to meet these production
expectations will have a material adverse effect on the Company's projected
results of operations.  Greenver's facilities currently are not growing tomatoes
hydroponically.  As a result, there can be no assurance the tomatoes grown at
the Greenver greenhouses will not suffer from soil-born contaminants that could
effect their quality.  Within the next 18 months, the Company intends to assist
Greenver in converting a portion of its facilities to hydroponic production.
There can be no assurance that the Company will be able to implement
successfully these hydroponic systems or that, once implemented, Greenver will
be able to continue to produce tomatoes of superpremium quality.  Any failure by
Greenver to produce the quality of tomatoes anticipated by the Company could
have a material adverse effect on the Company's projected results of operations.
As part of its arrangement with Greenver, the Company will receive 25% of all
distributions made by Greenver to its stockholders.  There can be no assurance,
however, that Greenver will be profitable or that it actually will make cash
distributions of its profits, if any, in the future.  See "Business--Greenver
Transaction and Marketing Agreement."

  The Company may be affected by economic, political and social conditions in
Mexico.  Mexico has experienced political, economic and social uncertainty in
recent years, including an economic crisis characterized by exchange rate
instability and peso devaluation, increased inflation, high domestic interest
rates, negative economic growth, reduced consumer purchasing power and high
unemployment.  Under its current leadership, the Mexican government has been
pursuing economic reform policies, including the encouragement of foreign trade
and investment and an exchange rate policy of free market flotation.  No
assurance can be given, however, that the Mexican government will continue to
pursue these policies, that these policies will be successful if pursued or that
these policies will not be significantly altered.  A decline in the Mexican
economy, political or social problems or a reversal of Mexico's foreign
investment policy is likely to have an adverse effect on the market price of the
Common Stock and may adversely affect the Company's results of operations and
financial condition.

  While the Company transacts business with Greenver in U.S. dollars and sales
of Greenver's tomatoes are made in U.S. dollars, all of Greenver's production
and related expenses are denominated in pesos.  Accordingly, inflation in Mexico
may lead to higher wages and salaries for the Greenver's employees in Mexico and
increase the cost of the raw materials used in the production of Greenver's
products, which would adversely affect Greenver's profitability and the level of
distributions, if any, to the Company based on its equity ownership in Greenver.

  Risks inherent in foreign operations include nationalization, war, terrorism
and other political risks and risks of increases in foreign taxes or U.S. tax
treatment of foreign taxes paid and the imposition of foreign government
royalties and fees.

Loss of Greenhouse Leases; Dependence on Cogeneration Facility Contracts

  The Company currently leases four of its greenhouses, Rifle, Brush #1, Brush
#2 and Fort Lupton #1, which account in the aggregate for 71 of the 111 acres
the Company currently has under production.  The Company also leases the land on
which the Grants greenhouse is being constructed.  Each of the Company's four
leased greenhouses is operated pursuant to an Operating and Management Agreement
that has a term coincidental with the term of the underlying greenhouse lease.
The remaining terms of these greenhouse leases are four, six, 11 and 21 years
for the Rifle, Brush #1, Brush #2 and Fort Lupton #1 greenhouses, respectively.
The remaining term of the land site lease for Grants is 60 years. There can be
no assurance that these leases can be renewed at rents and other terms that are
as favorable to the Company as the existing terms.  The failure by the Company
to renew these leases, or the renewal of these leases on less favorable terms to
the Company, could force the Company to seek new greenhouse facilities and could
have a material adverse effect on the Company.

  The Company's four leased greenhouses serve as collateral for the lenders to
the cogeneration power plants next to which they are located.  For three of
these greenhouses, Brush #1, Brush #2 and Rifle, an event of default by the
borrower could result in the lender's foreclosing on these facilities and
canceling the Operating and Management Agreement, notwithstanding the fact that
the greenhouse lease, and related Operating and Management Agreement, are

                                       13
<PAGE>
 
not in default. Any foreclosure and cancellation of the Operating and Management
Agreement is likely to result in a loss of the Company's right to operate the
related greenhouse, which would adversely affect the Company's results of
operations and projected growth. See "Business--Facilities."

Reliance on Growers

  The Company's hydroponic operations require the skill of senior growers who
monitor the progress of the crops, as well as incidents of infestation or root
disease.  These senior growers must be experts in hydroponic and greenhouse
growing techniques.  The Company's failure to attract and retain an adequate
number of skilled growers is likely to effect adversely the quality and
production of its tomatoes and, therefore, its results of operations.  Further,
only one of the Company's six senior growers is a U.S. citizen.  As a result, if
senior growers have difficulty retaining visas or obtaining U.S. citizenship,
the Company would be forced to recruit replacement growers, most likely in
Europe.  See "Business--Employees and Training."

Substantial Competition
    
  The market for the Company's tomatoes is highly competitive and subject to
rapid change. The Company competes in the tomato market both with other
hydroponic greenhouse tomato producers and with commercial producers of field-
grown tomatoes, both gas green (in which the tomatoes are picked green and
colored via ethylene gas during shipping) and vine ripened. During 1997, field-
grown tomatoes accounted for approximately 92% of total U.S. fresh tomato
production, while hydroponic greenhouse tomatoes, both domestic and imported,
accounted for the remaining approximately 8%. Most field-grown tomatoes are sold
at wholesale at approximately one-half the price of the Company's greenhouse
grown tomatoes. During the local growing season, typically late summer, the
Company also competes with home- and locally-grown tomatoes. Field-grown tomato
competitors include numerous local and regional growers as well as a number of
major grower-shippers in the United States and Mexico, including DiMare (Florida
and California), Gargiulo (Florida and California), R&B Packing (Mexico) and
Meyers (Mexico). These major grower-shippers ship substantially more tomatoes
than the Company, have longer standing relationships with various retailers and
wholesalers and have greater financial resources than the Company. The Company's
competition in the hydroponic greenhouse tomato market comes from various
domestic and foreign hydroponic greenhouse tomato producers and cooperatives,
including domestic producers Eurofresh (with greenhouses in Arizona), Village
Farms (with greenhouses in New York, Pennsylvania, Texas, and Virginia) and BC
Hothouse (with greenhouses in California). The Company estimates that worldwide,
hydroponic greenhouse tomatoes currently originate from approximately 700 acres
in the United States (including the approximately 111 acres owned by the
Company), approximately 900 acres in Canada and an estimated aggregate of more
than 5,000 acres in Belgium, France, Israel, Morocco, The Netherlands and Spain.
Some portion of the foreign produced hydroponic tomatoes are sold in the United
States. Most of these sources produce high-quality tomatoes superior in taste,
texture and appearance to most field-grown tomatoes and generally comparable in
quality to the Company's tomatoes. The Company cannot predict if or when these
competitors or others may construct additional greenhouses and whether any
additional greenhouses will be constructed in the regions in which the Company
currently competes. There can be no assurance that the Company can maintain its
competitive position against current and potential competitors, especially those
with financial, marketing, personnel and other resources greater than the
Company's. See "Business--Competition."    

Customer Concentration

  During 1997, 79.0% of the Company's net sales were to its ten largest
customers.  In particular, sales to Safeway, Meijer and King Soopers represented
23.5%, 15.3% and 14.0% of the Company's total net sales, respectively.  The
Company expects that a small number of large supermarket chains will continue to
account for a substantial portion of its net sales for the foreseeable future.
There can be no assurance that the Company's principal customers will continue
to purchase products from the Company at current levels, if at all.  The
Company's loss of even one of these large customers due to production
shortfalls, quality concerns or otherwise is likely to adversely affect the
Company's results of operations and could affect the Company's planned growth.
Consistent with industry practice, the Company does not operate under long-term
supply contracts with any of its customers.  The loss of, or a significant
reduction in orders from, any one of these large customers, losses arising from
disputes between the Company and any one of these large customers regarding
shipments, fees, tomato condition or related matters, or the Company's inability
to collect accounts receivable

                                       14
<PAGE>
 
from any major retail customer could have a material adverse effect on the
Company. See "Business--Customers and Product Distribution."

Government Regulation

  The manufacture, processing, packaging, storage, distribution and labeling of
food products are subject to extensive federal, state and foreign laws and
regulations.  In the United States, the Company's business is subject to
regulation by the Food and Drug Administration ("FDA"), the United States
Department of Agriculture ("USDA") and various state and local agricultural and
public health authorities.  The FDA and USDA regulators charged with enforcing
these laws and regulations have broad powers to protect public health, including
the power to inspect produce and the Company's facilities, to order the shut
down of a facility or the suspension of delivery of the Company's produce, as
well as the power to impose substantial fines.  The Company also is subject to
various federal and state regulations relating to workplace safety and worker
health, including the Fair Labor Standards Act, Occupational Safety and Health
Act and laws and regulations governing such matters as minimum wages, overtime
and working conditions.  The Company is subject to various federal, state and
local environmental regulations.

  The Company may become subject to additional laws or regulations administered
by the FDA, the USDA or other federal, state, foreign or local regulatory
authorities, the repeal of laws or regulations or more stringent interpretations
of current laws or regulations.  The Company cannot predict the nature of any
new laws, regulations or interpretations, or what effect they might have on its
business.  Changes in these laws could require the reconfiguration of the
Company's production, processing and transportation methods or increased
compliance costs, and could require the Company to make significant capital
expenditures or incur higher operating costs.  Any failure by the Company to
comply with applicable laws and regulations could subject the Company to civil
penalties, including fines, injunctions, greenhouse or pack house closings,
recalls or seizures, as well as potential criminal sanctions, any of which could
have a material adverse effect on the Company.  See "Business--Government
Regulation."

Risks Related to Growth Strategy

  The Company is planning substantial growth in its production capabilities over
the next several years, which will place greater demands on its operating,
administrative and financial resources.  Future growth will depend on a number
of factors, including the timely construction of additional greenhouses, the
Company's ability to maintain the quality of the tomatoes it produces and the
recruitment and retention of qualified personnel.  Sustaining profitable growth
will also require the implementation of enhancements to the Company's operating
and financial systems and will require additional management, operating and
financial personnel.  There can be no assurance that the Company will be able to
manage its expanding operations effectively or that it will be able to implement
its growth plan, and any failure to do so is likely to have a materially adverse
effect on the Company's business, results of operations and financial condition.
See "Business--Growth Strategy."

Dependence on Key Personnel; Short Operating History Under Current Management

  The Company's continued success will depend largely on the skills and
abilities of its officers, key employees and directors.  Specifically, the
Company is highly dependent upon its Chief Executive Officer, James R. Rinella,
its Executive Vice President of Production, Matthew B. Cook, its Vice President
of Finance, Alan R. Fine and its Director of Agricultural Production, Ludo van
Boxem.  The loss of any one of these persons could have a material adverse
effect on the Company.  In addition, Mr. Rinella and Mr. Fine both joined the
Company in the fall of 1997.  Accordingly, the Company has only a limited
history of operation under its current management team upon which investors may
evaluate its performance.  There can be no assurance that the Company's new
management team will be able to achieve or sustain revenue growth or
profitability.  See "Management."

  The Company's success depends also on its ability to attract, retain and
motivate highly qualified growers and marketing, sales and other management
personnel.  Failure to continue to attract and retain a sufficient number of
these personnel could have a material adverse effect on the Company's results of
operations and planned growth.  There is intense competition for qualified
personnel and there can be no assurance that the Company will be able to attract
and retain the qualified personnel necessary for the successful operation of its
business.  See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business--Employees and Training."

Control by Existing Stockholders
    
  Upon completion of this offering, the Company's officers, directors and
existing principal stockholders will beneficially own an aggregate of
approximately 50% of the outstanding shares of Common Stock.  If these persons
were to act together, they would be able to elect all of the Company's directors
and determine the outcome of all corporate actions requiring approval by the
stockholders, thus controlling the business affairs and policies of the Company.
This control could have the effect of delaying or preventing a change in control
of the Company and consequently, may adversely affect the market price of the
Common Stock.  See "Principal Stockholders."      

No Prior Market; Determination of Offering Price; Volatility of Stock Price

  Prior to this offering, there has been no public market for the Common Stock.
Although application has been made to list the Common Stock on the Nasdaq
National Market/sm/, there can be no assurance that an active trading market
will develop or be sustained, and no assurance that the price at which the
Common Stock may trade in the public market after this offering will exceed the
initial public offering price. The initial public offering price will be
determined by negotiations between the Company and the Representatives of the
Underwriters.  See "Underwriting" for a discussion of the factors considered in
determining the initial public offering price.  The trading price of the
Company's Common Stock could be subject to wide fluctuations in response to
quarter-to-quarter variations in the Company's operating results, material
announcements by the Company, governmental regulatory action, general conditions
in the fresh produce industry or other events or factors, many of which are
beyond the control of the Company.  In addition, the Company's future operating
results may be below the expectations of securities analysts and investors.  In
such event, the price of the Common Stock would likely decline, possibly
substantially.

Shares Eligible for Future Sale
    
  Upon consummation of this offering, the Company will have outstanding
13,998,361 shares of Common Stock.  Of these shares, the 5,000,000 shares sold
in this offering will be freely tradable without restriction under the
Securities Act, unless purchased by "affiliates" of the Company as that term is
defined in SEC Rule 144.   All of the remaining 8,998,361 shares of Common Stock
are "restricted securities" within the meaning of Rule 144 and may be sold in
the public market only if registered or if sold under an exemption from
registration under the Securities Act, including the exemption provided by Rule
144.  Approximately 7,918,032 shares of these restricted securities have been
held for more than one year and will be immediately saleable under Rule 144,
subject to the Underwriters' lock-up and the volume limitations imposed by Rule
144.  In addition, some of the Company's existing stockholders have the right to
require the Company to register their Common Stock from time to time.  See
"Description of Capital Stock--Registration Rights" and "Shares Eligible for
Future Sale."      

  Sales of substantial amounts of the Common Stock in the public market, or the
perception that such sales could occur, may adversely affect the market price of
the Common Stock and could impair the Company's future ability to raise capital
through an offering of its equity securities.  The Company is unable to predict
the effect, if any, that future sales of Common Stock or the availability of
Common Stock for sale may have on the market price of the Common Stock
prevailing from time to time.

Certain Anti-Takeover Provisions

  Certain provisions of Delaware law and the Company's Amended and Restated
Certificate of Incorporation (the "Charter") and Amended and Restated Bylaws
(the "Bylaws") may have the effect of delaying, deterring or preventing a future
takeover or change in control of the Company unless such takeover or change in
control is approved by the Company's Board of Directors.  These provisions also
may render the removal of directors and management more difficult and could
limit the price that investors might be willing to pay in the future for shares
of the Company's Common Stock.  These provisions of Delaware law and the
Company's Charter and Bylaws may also have the effect of discouraging or
preventing certain types of transactions involving an actual or threatened
change of control of the Company (including unsolicited takeover attempts), even
though such a transaction may offer the Company's stockholders the opportunity
to sell their stock at a price above the prevailing market price.  See
"Description of Capital Stock--Anti-Takeover Provisions."

Immediate and Substantial Dilution
    
  Purchasers of Common Stock in this offering will experience immediate and
substantial dilution of $5.72 in the net tangible book value per share of the
Common Stock.  See "Dilution."

                                USE OF PROCEEDS
    
  The net proceeds to the Company from the sale of shares of Common Stock
offered hereby are estimated to be $32.0 million (assuming an initial public
offering price of $10.00 per share), after deducting underwriting discounts and
commissions and estimated offering expenses.  The Company intends to use the net
proceeds as follows: (i) approximately $15.0 million to repay a portion of its
existing indebtedness (including prepayment penalties of approximately
$550,000); (ii) approximately $10.0 million to finance a portion of the cost of
construction of two or three of the six planned 20-acre hydroponic greenhouse
facilities; and (iii) the balance for working capital to support the Company's
marketing agreement with Greenver and its planned growth.      

  The indebtedness to be repaid was incurred under a (i) a $15.0 million term
loan (the "Term Loan") and (ii) a $7.5 million construction loan (the "Grants
Loan"), all with the Colorado Springs Production Credit Association ("Farm
Credit").  The proceeds of the Term Loan were used for the construction of the
Estancia and Fort Lupton #2 greenhouses, and the proceeds of the Grants Loan are
being used for the construction of the Grants greenhouse.  The Term Loan has an
interest rate of 8.19% per annum and matures in May 2007, and the Grants Loan
bears interest at the prime rate plus 0.5% and matures upon completion of
construction.  At June 1, 1998, the prime rate was 8.5%.
    
  The Company currently intends to construct up to six additional 20-acre
hydroponic greenhouse facilities, two of which are expected to be adjacent to
the existing, or under construction, facilities in Estancia and Grants, New
Mexico. The Company estimates that the current cost to construct a 20-acre
hydroponic greenhouse facility is approximately $13.0 million and the cost to
construct two adjacent 20-acre hydroponic greenhouse facilities is approximately
$25.0 million.  The Company believes a substantial portion of these costs can be
financed by those commercial lenders with which the Company has had preliminary
discussions.  The Company currently anticipates that construction of at least
two of these facilities will commence by mid-1999.  See  "Business--Facilities."
     
  Pending application of the net proceeds as described above, the Company will
invest them in short-term interest bearing, investment grade securities.


                                DIVIDEND POLICY

  The Company has never paid cash dividends on its capital stock although during
1996, the Company paid distributions of approximately $1.7 million to cover the
LLC's members' tax obligations. The Company currently intends to retain
earnings, if any, to finance the growth and development of its business and does
not anticipate paying cash dividends in the foreseeable future.  In addition,
the Company's credit facilities with Farm Credit currently prohibit the payment
of cash dividends.  Any payments of cash dividends in the future, if permitted
by the Company's credit facilities, will be at the discretion of the Board of
Directors after taking into account various factors, including the Company's
financial condition, results of operations, cash flows from operations, current
and anticipated cash needs and expansion plans, income tax laws then in effect
and requirements of Delaware law.

(1) Assuming an initial public offering price of $10.00 per share, the Series B
    Preferred Stock will convert automatically into 3,185,216 shares of Common
    Stock.  If the initial public offering price is higher than $10.00, the
    Series B Preferred Stock will convert automatically into a fewer number of
    shares of Common Stock.  For example, if the initial public offering price
    is $11.00 per share, the Series B Preferred Stock will convert automatically
    into 3,030,680 shares of Common Stock.      
(2) Excludes 1,026,691 shares of Common Stock issuable upon the exercise of
    currently outstanding options at a weighted average exercise price per share
    of $2.65.  See "Management--Stock Option Plan."

                                    DILUTION
    
  The net tangible book value of the Company as of June 30, 1998, as adjusted
for the conversion of all outstanding preferred stock and the cashless exercise
of the Warrant, was approximately $28.4 million or $2.71 per share.  Net
tangible book value per share is determined by subtracting the Company's total
liabilities from its total tangible assets and dividing the remainder by the
number of shares of Common Stock outstanding assuming the conversion of all
outstanding preferred stock and the Warrant.  After giving further effect to the
sale by the Company of 3,500,000 shares of Common Stock in this offering (at an
assumed initial public offering price of $10.00 per share) and application of
the estimated net proceeds therefrom, the net tangible book value of the Company
as of June 30, 1998 would have been $59.9 million or $4.28 per share.  This
represents an immediate increase in net tangible book value of $1.57 per share
to existing stockholders and an immediate dilution in net tangible book value of
$5.72 per share to purchasers of Common Stock in this offering.  The following
table illustrates this dilution in net tangible book value per share to new
investors:

(1) The Company was organized in 1993 to operate three greenhouses and 
    incurred marketing expenses in anticipation of these operations. Effective
    January 1, 1994, the Company began to operate three greenhouses (Brush #1,
    Brush #2 and Fort Lupton #1). Effective January 1, 1996, the Company began
    to operate a fourth greenhouse (Rifle). During October 1997, the Company
    began production from its fifth greenhouse (Estancia), and in March 1998,
    the Company began production from its sixth greenhouse (Fort Lupton #2).

(2) Operating expenses for 1997 have been reduced to reflect insurance proceeds
    of $802,000 from the flood in July 1997 at Fort Lupton #1. Operating
    expenses for the six months ended June 30, 1998, include a loss of
    $1,700,000 resulting from the hail storm in May 1998 at Brush #1 and Brush
    #2 and have been reduced to reflect insurance proceeds of $1,608,000.

(3) Prior to January 1997, the Company was operated as a limited liability
    company and was not subject to federal or state income taxes. As a result,
    the provision (benefit) for income taxes and net income (loss) for the years
    1993 to 1996 are presented on a pro forma basis as if the Company were
    subject to federal and state corporate income taxes, assuming an effective
    tax rate of 38%. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations--Introduction."

(4) Average yield sold per acre on a annual basis is calculated by dividing the
    total number of pounds sold by the total number of acres in production.
    Average yield sold per acre for 1997 is a weighted average of 76 acres based
    on the increase of total acres in production during the year as a result of
    the Estancia greenhouse, which began production in October 1997. Management
    believes that average yield per acre sold is an important measure of
    greenhouse productivity. 

(5) Working capital as of June 30, 1997, includes the net proceeds from the
    issuance of the Series B Convertible Preferred Stock, less amounts expended
    through that date.

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

  The following discussion of the financial condition and results of operations
of the Company should be read in conjunction with the Company's Consolidated
Financial Statements and the Notes thereto included elsewhere in this
Prospectus.

Introduction
    
  The Company currently operates six hydroponic greenhouses covering
approximately 111 production acres in Colorado and New Mexico and is
constructing a seventh 20-acre hydroponic greenhouse in New Mexico. The Company
plans to construct six additional 20-acre hydroponic greenhouses over the next
three years. The Company's production sold was approximately 247,000 pounds per
acre for the six months ended June 30, 1998, which represents an approximately
29% increase from the same period in 1996. The Company also has increased its
acreage by approximately 56% and increased its net sales by approximately 77%
over the same period. In May 1998, the Company acquired the exclusive right to
market in the United States, Canada and Europe all export-quality tomatoes from
Greenver's approximately 175 acres of non-hydroponic greenhouses in Mexico, half
of which are currently under construction and expected to be in production by
November 1998. The Company anticipates that Greenver will provide it with up to
18 million pounds of tomatoes during Greenver's November 1998 through April 1999
growing season.      

  The Company's tomatoes are sold directly to both national supermarket chains
and regional wholesalers.  Sales are recognized at the time of shipment and are
presented net of approved credits and allowances.  Cost of goods sold consists
of direct and indirect costs.  Direct costs are recorded at the time related
revenues are recognized while indirect costs are recorded systematically over
the year.  The principal components of direct costs are greenhouse, pack house
and related management payroll, growing expenses, packing materials and freight
costs.  Throughout the year, greenhouse payroll remains relatively stable
because the crops require constant inspection and maintenance.  Indirect costs
include rent and depreciation expense associated with the greenhouses and pack
houses.

  Operating expenses consist primarily of payroll expense for administrative
personnel, stock-based compensation, marketing and promotional program costs,
insurance expenses, professional fees and other administrative costs.  In 1996,
the Company granted stock options at an exercise price of $0.74 per share, which
resulted in stock-based compensation. This stock-based compensation, determined
as the excess of the fair market value of the stock over the stock option's
exercise price, is being expensed over the vesting period of the option.  The
Company incurred $715,000 and $540,000 of stock-based compensation expense in
1996 and 1997, respectively.  Any stock-based compensation expense for periods
after 1997 is not expected to be material.

  The Company will account for its 25% equity investment in Greenver using the
equity method of accounting.  The Company and Greenver have agreed to make an
annual determination regarding the amount, if any, of distributions to
Greenver's shareholders.  Any distributions are expected to be made in the third
quarter of each year.  The Company expects Greenver to distribute all profits
remaining after funding Greenver's reserve account to an agreed amount.  The
marketing agreement for the sale of Greenver's tomatoes will generate net
commission income to the Company, consisting of the Company's 10% commission
less marketing expenses associated with the sale of Greenver's tomatoes.

  Effective January 1, 1997, the Company became a C Corporation for federal and
state income tax purposes.  Prior thereto, the Company was a limited liability
company ("LLC") and, therefore, did not pay corporate or state income taxes.
The pro forma provision for income taxes for years prior to 1997 assumes the
Company was subject to federal and state income taxes applicable to C
Corporations and has been calculated using an effective rate of 38%.

  During 1997, the Company experienced mechanical problems, pest and disease
infestations and a flood that significantly reduced production during parts of
the year in three of the Company's greenhouses.  In the Brush #1 greenhouse, a
root disease reduced tomato production by approximately 18.9% during the first
and second quarters of 1997.  This was followed in the third quarter by an
invasion of thrips (an insect) through the greenhouse's unscreened ventilation
system, which carried a virus from adjacent agricultural field crops.  This
virus reduced plant populations as well as tomato volumes and size, resulting in
a decline in the Company's average sales price per pound.  During the third
quarter of 1997, Brush #2 was also affected negatively by the same root disease
that affected Brush #1 and was infested with a large population of whiteflies.
This led to the Company's decision to pull out its entire existing crop at Brush
#2 

                                       23

and disinfect the greenhouse at the beginning of the fourth quarter of 1997.
At the end of the first quarter of 1997, the Fort Lupton #1 greenhouse
experienced a mechanical failure in its irrigation system, followed by a flood
at the end of July that required the Company to pull out the entire crop to
avoid an outbreak of root rot common in water damaged crops.  As a result of all
of these problems, the Company experienced approximately a 13% decline in total
production sold in 1997 compared to 1996, despite the addition of production
from the 20-acre Estancia greenhouse in October 1997.      
    
  The Company believes it has remedied the problems that lead to mechanical
malfunctions and has used the experiences to update its existing greenhouses and
better design future greenhouses.  The Company hired a new senior management
team that has implemented various initiatives and quality control measures to
reduce the likelihood of similar problems occurring in the future and obtained
improved insurance coverage.  The Company had direct damage insurance covering
both property damage to its greenhouses and lost profits and was able to recover
$802,000 as a result of the damage from the flood.  This recovery represented
approximately one-half of the lost sales that resulted from the flood, which
subsequently caused management to obtain new insurance coverage.  Management
believes that its new insurance policy will more adequately protect it in the
event of a catastrophic loss, such as the May 1998 hail storm described below.
     
  As a result of the 1997 production problems, the Company generated a net
operating loss ("NOL") carry forward for both federal and state income tax
reporting purposes of approximately $2.3 million.  The Company expects that a
majority, if not all, of the NOL will be used in 1998.  Accordingly, the Company
recorded an income tax benefit of approximately $653,000 during 1997.  The
Company expects to recognize income tax expense for financial reporting purposes
at an effective rate of approximately 38%.
    
  The Company maintains business interruption insurance and property damage
policies with aggregate limits of coverage of $33 million, limited to $5.0
million per occurrence.  The Company has received an advance of $2.0 million for
its claims from the hail damage incurred at the Brush #1 and Brush #2
greenhouses to fund the cost of cleanup, building repair, miscellaneous fixed
expenses and re-establishing the crop.  Due to the nature of the business
interruption claims, final settlement will not be possible until such time as
the Company has returned to normal operations, which is anticipated to be by
December 1, 1998.  See "Risk Factors--Risk of Catastrophic Loss of Crop and
Other Property Damage."

(1) Operating expenses for 1997 have been reduced to reflect insurance proceeds
    of $802,000 from the flood in July 1997 at Fort Lupton #1.  Operating
    expenses for the six months ended June 30, 1998, include a loss of
    $1,700,000 resulting from the hail storm in May 1998 at Brush #1 and Brush
    #2 and have been reduced to reflect insurance proceeds of $1,608,000.     
(2) Prior to January 1997, the Company was operated as a limited liability
    company and was not subject to federal or state income taxes.  As a result,
    the net income (loss) for the years 1995 to 1996 are presented on a pro
    forma basis as if the Company were subject to federal and state corporate
    income taxes, assuming an effective tax rate of 38%.
    
  Six Months Ended June 30, 1998 and 1997      
    
  Net Sales.  Net sales increased by $10.2 million, or 77.1%, to $23.5 million
on sales of 25.8 million pounds of tomatoes for the six months ended June 30,
1998, compared to net sales of $13.3 million on sales of 13.6 million pounds of
tomatoes for the same period in 1997.  These increases were due primarily to the
addition of the 20-acre Estancia greenhouse, which came into production in
October 1997, and the 20-acre Fort Lupton #2 greenhouse, which came into
production in March 1998.  In addition, the Company increased its production
yield by approximately 29.3% to 247,000 pounds per acre in the first half of
1998 from 191,000 pounds per acre in the comparable period of 1997.  This
increase in yield was attributable to management's increased focus on production
and to changes in production methods in response to the production problems
experienced at the Fort Lupton #1 greenhouse in 1997.  Higher production in 1998
was partially offset by a lower sale price per pound as prevailing market prices
during the first quarter of 1997 were higher than in 1998 due to adverse weather
conditions that impaired the field-grown tomato supply in early 1997.  As a
result, the Company realized a $0.98 average sale price per pound of tomatoes
during the first half of 1997, compared to $0.91 for the comparable period in
1998.      
    
  Gross Profit.  The Company's gross profit for the six months ended June 30,
1998 was $7.6 million, or 32.1% of net sales, compared to $1.8 million, or 13.5%
of net sales, for the six months ended June 30, 1997.  This dollar increase in
gross profit was due to the increase in total pounds of tomatoes sold, resulting
from the additional 40 acres of greenhouse facilities and the increase in yield
per acre, despite the lower average sale price per pound.  The 1997 production
problems and higher than expected greenhouse labor costs resulted in a lower
than expected gross profit in the first half of 1997.  Greenhouse labor costs in
the first half of 1997 were higher than normal as a result of training expenses
for additional greenhouse personnel to staff the Estancia greenhouse in October
1997.  The Company expects that it will continue to incur higher than normal
greenhouse labor costs as a result of training expenses for additional
greenhouse personnel in those quarters in which it adds additional greenhouse
facilities.      
    
  Operating Expenses.  During the six months ended June 30, 1998, operating
expenses were $3.0 million, or 12.7% of net sales, compared to $2.3 million, or
17.0% of net sales, for the six months ended June 30, 1997.  The components of
the dollar increase were: (i) a $0.5 million increase in general and
administrative expenses due to the additions to senior management, higher
incentive bonus accruals and higher professional fees;  and (ii) a $0.2 million
increase in sales and marketing expenses due to the Company's new marketing
program that will begin in the fall of 1998.  The 77.1% increase in net sales
during the first half of 1998 caused the substantial decline in operating
expenses as a percentage of net sales.  Management expects that operating
expenses may increase during the next several years as the Company implements
its consumer branding strategy, implements the Greenver marketing agreement and
becomes a public company.      
    
  Operating Income (Loss).  The Company generated operating income of $4.6
million, or 19.4% of net sales,  for the six months ended June 30, 1998,
compared to operating loss of $0.5 million, or (3.5%) of net sales, for the
comparable period in 1997.  This improvement resulted from the 77.1% increase in
net sales and the higher gross margin in the first half of 1998.      
    
  Interest and Other Income (Expense), Net.  The Company incurred interest and
other expense of $0.3 million for the six months ended June 30, 1998, compared
to interest and other income of $0.2 million for the six months ended June 30,
1997.  This increase was due to interest expense on debt incurred to finance
construction of the Estancia and Fort Lupton #2 greenhouses.      
    
  Net Income (Loss).  The Company generated net income of $2.6 million, or 11.2%
of net sales, for the six months ended June 30, 1998, compared to a net loss of
$0.1 million, or (0.9%) of net sales, for the comparable period in 1997. The
Company's provision for income taxes was $1.7 million and ($0.1) million for the
six months ended June 30, 1998 and 1997, respectively, representing an effective
tax rate of 38% in both periods.      

                                       25

  1997 Compared to 1996

  Net Sales. Net sales decreased by $2.5 million, or 9.1%, to $24.9 million on
sales of 26.2 million pounds of tomatoes in 1997, compared to net sales of $27.4
million on sales of 30.0 million pounds of tomatoes in 1996.  This decrease in
net sales was due to production shortfalls that resulted from the problems
experienced by the Company at three of its greenhouses at various times during
1997, partially offset by the addition of production at the Estancia greenhouse
in October 1997.   The Company realized a 4.4% increase in the average sale
price per pound of tomatoes to $0.95 in 1997 from $0.91 in 1996.

  Gross Profit.  The Company's gross profit for 1997 was $2.7 million, or 10.8%
of net sales, compared to $8.1 million, or 29.6% of net sales, in 1996.   The
dollar decrease resulted from the mechanical problems, pest and disease
infestation and flood that significantly reduced production and the number of
pounds sold in 1997.  The decline in the gross profit margin was attributable to
the fact that a significant portion of greenhouse operating expenses are fixed.

  Operating Expenses.  During 1997, operating expenses were $4.6 million, or
18.5% of net sales, compared to $4.4 million, or 16.2% of net sales, in 1996.
The principal components of the dollar increase were: (i) a $0.4 million
increase in administrative payroll and related expenses, (ii) a $0.4 million
increase in computer-related expenses and (iii) a $0.2 million increase in
travel expenses.  These increases were partially offset by the $0.8 million
insurance recovery from the flood at Fort Lupton #1.

  Operating Income (Loss).  The Company generated an operating loss of $1.9
million for 1997, compared to operating income of $3.7 million, or 13.4% of net
sales, for 1996.  The difference was attributable to the factors discussed
above.

  Net Income (Loss).  The Company recognized a net loss of $1.1 million for
1997, compared to net income of $2.3 million, or 8.4% of net sales, for 1996,
presented on a pro forma basis to reflect pro forma income taxes calculated at
an effective tax rate of 38%.

  1996 Compared to 1995

  Net Sales. Net sales increased by $7.3 million, or 36.3%, to $27.4 million on
sales of 30.0 million pounds of tomatoes for 1996, compared to net sales of
$20.1 million on sales of 24.4 million pounds of tomatoes for 1995.  Of this
increase in net sales, approximately two-thirds was attributable to the addition
of the Rifle greenhouse on January 1, 1996, and approximately one-third was
attributable to a 9.6% increase in the average sale price per pound of tomatoes
to $0.91 in 1996 from $0.83 in 1995.

  Gross Profit.  The Company's gross profit for 1996 was $8.1 million, or 29.6%
of net sales, compared to $4.7 million, or 23.4% of net sales, for 1995.  This
dollar increase was attributable primarily to the increase in production from
the addition of the Rifle greenhouse, as well as the $0.08 per pound increase in
the average sales price for 1996. The improvement in the gross profit margin was
primarily attributable to the fact that a significant portion of greenhouse
operating expenses are fixed.

  Operating Expenses.  During 1996, operating expenses were $4.4 million, or
16.2% of net sales, compared to $2.5 million, or 12.4% of net sales, for 1995.
The principal components of the dollar increase were: (i) $1.2 million of higher
payroll and related costs (including stock-based compensation of $0.7 million),
(ii) $0.2 million of Rifle greenhouse expenses, and (iii) a $0.2 million
increase of professional fees and insurance costs.

  Operating Income (Loss).  The Company generated operating income of $3.7
million, or 13.4% of net sales, for 1996, compared to $2.2 million, or 11.0% of
net sales, for 1995.  These increases were the result of the increased
production and higher margins discussed above.

   Net Income (Loss). The Company generated pro forma net income of $2.3
million, or 8.4% of net sales,  in 1996, compared to $1.6 million, or 7.8% of
net sales, for 1995.  These amounts have been presented on a pro forma basis to
reflect income taxes calculated at an effective tax rate of 38%.

Liquidity and Capital Resources
    
  The Company's working capital was $3.0 million and $6.3 million at December
31, 1997 and June 30, 1998, respectively.  The Company's primary sources of
liquidity have been cash flows from operations, a $1.5 million revolving credit
facility with Farm Credit and the occasional sale of preferred stock.  Primary
uses of cash have been greenhouse operations and construction of the Estancia,
Fort Lupton #2 and Grants greenhouses.  The following table sets forth a summary
of the Company's cash flows for the periods presented:

</TABLE>     
    
  The $2.2 million decrease in net cash flows from operations from the six
months ended June 30, 1997, to the six months ended June 30, 1998, was due
primarily to a $3.0 million decrease in construction payables and the
recognition of a $2.0 million insurance receivable related to the hail loss,
offset by a $2.8 million increase in operating income.  The $1.7 million
decrease in net cash flows from operations from 1996 to 1997 was due primarily
to the production problems previously discussed, the start-up of two new
greenhouses and an increase in trade and other receivables, partially offset by
an increase in construction payables.  The $1.4 million decrease in net cash
flows from operations from 1995 to 1996 was due primarily to the required
funding of rent reserves equal to one year's rent at three of the Company's four
leased greenhouses.     
    
  The $3.4 million decrease in net cash flows used in investing activities from
the six months ended June 30, 1998, to the six months ended June 30, 1997, was
attributable to a $4.0 million investment in Greenver and $4.1 million of
greenhouse construction related to the completion of the Estancia and Fort
Lupton #2 greenhouses in 1998, compared to $11.4 million of greenhouse
construction in 1997.  The $22.6 million increase in net cash used in investing
activities from 1996 to 1997 was attributable to $21.8 million for the
construction of the two greenhouses and the balance for the acquisition of a new
computer system.  These capital expenditures were financed by $13.5 million of
net proceeds from the sale of Series B Convertible Preferred Stock in January
1997 and $11.0 million in construction financing from Farm Credit.     
    
  The $5.4 million decrease in net cash flows provided by financing activities
from the six months ended June 30, 1998, to the six months ended June 30, 1997,
was primarily attributable to $5.9 million of net proceeds from the sale of
Series C Convertible Preferred Stock in May 1998 and $4.0 million of proceeds
drawn against construction loans in 1998, compared to $13.5 million of net
proceeds from the sale of Series B Convertible Preferred Stock in January 1997
and $0.8 million of construction loan advances in 1997.   The $26.3 million
increase in net cash flows provided by financing activities from 1996 to 1997
was primarily attributable to the $13.5 million of net proceeds from the sale of
the Series B Convertible Preferred Stock and the $11.0 million of construction
financing from Farm Credit in 1997, compared to the $1.7 million distribution
made by the Company to cover the LLC members' income tax obligations on the
Company's taxable income in 1996.     
    
  In January 1997, the Company and Farm Credit entered into a Master Loan
Agreement ("MLA") that included a $15.0 million construction loan to finance
construction of the Estancia and Fort Lupton #2 greenhouses and a working
capital revolving line of credit of up to $1.5 million that bears interest at a
variable rate equal to 0.25% below the prime rate.  Borrowings under the MLA are
secured by substantially all of the Company's assets.  This construction loan
was converted to a term loan in May 1998, bearing interest at 8.19% per annum
and payable in 104 equal monthly payments that resulted in a loan balance of
$14.7 million as of June 30, 1998.  At December 31, 1997, the balance on the
construction loan was approximately $11.1 million.     

  Under the Greenver marketing agreement, the Company must reimburse Greenver
weekly for Greenver's production and transportation costs for tomatoes the
Company received during the previous week.  In addition, the Company must

                                       27
<PAGE>
 
remit to Greenver monthly the amount of sales of Greenver tomatoes, less costs
incurred during the month by the Company, the Company's sales commissions and
any transportation costs incurred by the Company from San Diego to its
customers. The Company anticipates that this will require additional working
capital because the Company's customers typically do not pay sales invoices in
less than 30 days. This additional working capital requirement of up to $6.0
million will be funded from the net proceeds from this offering. The Company
believes that cash flow from the operations of its greenhouses will be higher in
1998 than 1997 because of the addition of two new greenhouses, barring any other
adverse weather events or production problems.

  The Company plans to construct up to six new 20-acre greenhouses over the next
three years, in addition to the Grants greenhouse currently under construction.
The Company expects to finance partially the construction of these greenhouses
from the net proceeds of this offering and any cash flow from operations.
Additional construction financing will be required, however, for each new
greenhouse.  Farm Credit has provided construction financing of up to $7.5
million, or 60%, of the anticipated cost of constructing the Grants greenhouse,
estimated at $12.5 million.  The Company has not obtained financing commitments
for the other six greenhouses but believes that several sources of debt
financing will be available on acceptable terms.  If the Company were unable to
obtain debt financing on satisfactory terms, it might be forced to delay the
construction of one or more of the six planned greenhouses.

Seasonality; Quarterly Results

  The Company's business is seasonal, and its quarterly results of operations
reflect trends resulting from seasonal variations in production yields and
prevailing prices for tomatoes.  Price fluctuations and tomato availability have
a direct effect on the Company's financial results.  Typically, in the winter
months, the reduced supply of tomatoes (due primarily to the lack of field-grown
tomatoes) results in higher market prices.  Through the spring and summer
months, the supply of field-grown tomatoes increases, resulting in lower market
prices.  As a result, the Company historically has experienced higher profits in
the first and second quarters.  Although the Company's production in the first
quarter is lower due to fewer hours of direct sunlight, prevailing prices are
higher, and in the second quarter, the Company's production increases although
prevailing prices are lower.  Thereafter, profits typically have declined in the
third quarter as the Company experiences planned decreases in production to
coincide with expected lower market price periods.  In the fourth quarter,
profits typically have increased as the Company's production remains steady but
higher market prices return.    Greenver produces tomatoes in its Mexican
greenhouses only from November through May.  As a result of the Greenver
marketing agreement commencing in the fall of 1998, the Company's supply of
tomatoes during these months should increase significantly from 1997 and prior
years' supplies during the same months.  Accordingly, the Company expects that
its profitability will continue to be subject to large seasonal variations, and
the Company's results of operations for any particular quarter are not expected
to be indicative of results for subsequent quarters or the full year.

  The following table sets forth financial and operating data for the Company
for the quarters indicated:

- --------------------- 
(1) Gross profit in the quarter ended June 30, 1997, was significantly impacted
    by a root disease in the Brush #1 greenhouse that reduced tomato production
    by approximately 18.9%.  Gross profit in the quarter ended September 30,
    1997, was significantly impacted by a flood in July 1997 that destroyed
    production at Fort Lupton #1 and a root disease at Brush #2.
    
(2) Operating expenses for the quarter ended September 30, 1997 have been
    reduced to reflect insurance proceeds of $802,000 from the flood in July
    1997 at Fort Lupton #1.  Operating expenses for the quarter ended June 30,
    1998, include a loss of $1.7 million resulting from the hail storm in May
    1998 at the Brush #2 greenhouse, offset by the attributable portion ($1.6
    million) of the $2.0 million advance on insurance proceeds received by the
    Company.  See "--Introduction."     
(3) Prior to January 1997, the Company was operated as a limited liability
    company and was not subject to federal or state income taxes.  As a result,
    the  net income (loss) for the years 1993 to 1996 are presented on a pro
    forma basis as if the Company were subject to federal and state corporate
    income taxes, assuming an effective tax rate of 38%.  See "--Introduction."
         
Year 2000 Compliance
    
  Although the Company has not completed its testing, it believes that its
software and hardware systems can be made year 2000 compliant at minimal cost so
that they will recognize data fields beyond 1999.  As of June 30, 1998, the
Company has spent approximately $20,000 on its Year 2000 compliance issues and
expects to spend at least an additional $10,000 in completing its Year 2000
compliance issues.  All of these Year 2000 compliance expenses will be paid from
the Company's working capital reserves.  The Company does not believe that the
cost of Year 2000 compliance for its own hardware and software systems is
material. The Company expects that it will be Year 2000 compliant by the end of
1998.     
    
  The Company also is in the process of determining whether its major suppliers,
service providers and customers are, or will be, year 2000 compliant in a timely
fashion. If the Company's major suppliers, service providers and customers do
not become Year 2000 compliant in a timely fashion, the Company is not certain
of the impact, if any, that this may have on its future financial condition or
results of operations. The Company has not completed a contingency plan with
respect to its major suppliers, service providers and customers that are not
Year 2000 compliant. The Company intends to develop a contingency plan by the
middle of 1999 if it determines that some of its major suppliers, service
providers and customers will not become Year 2000 compliant in a timely fashion.

                                    BUSINESS

Overview
    
  Colorado Greenhouse is the largest U.S.-based producer and marketer of high-
quality greenhouse tomatoes.  The Company's branded superpremium tomatoes are
characterized by their excellent flavor, rich red color and consistent blemish-
free appearance.  The Company currently operates six hydroponic greenhouses
covering approximately 111 production acres in Colorado and New Mexico and is
constructing a seventh 20-acre hydroponic greenhouse in New Mexico.  The Company
plans to construct six additional 20-acre hydroponic greenhouses over the next
three years.  The Company's production sold was approximately 247,000 pounds per
acre for the six months ended June 30, 1998, which represents an approximately
29% increase from the same period in 1996.  The Company also has increased its
acreage by approximately 56% and increased its net sales by approximately 77%
over the same period.  In May 1998, the Company acquired an approximately 25%
equity interest in Greenver and obtained the exclusive right to market in the
United States, Canada and Europe all export-quality tomatoes from Greenver's
approximately 175 acres of non-hydroponic greenhouses in Mexico, half of which
are currently under construction and expected to be in production by November
1998.  The Company anticipates that Greenver will provide it with up to 18
million pounds of tomatoes during Greenver's November 1998 through April 1999
growing season.     

  The Company's production and distribution capabilities enable it to provide
its customers with a consistent, year-round supply of superpremium branded
tomatoes.  The Company currently markets most of its tomatoes in ten states,
primarily to major supermarket chains, including Albertson's, Ingles, King
Soopers, Kroger, Lucky's, Meijer and Safeway, with the majority of sales
concentrated in California, Colorado, Michigan, North Carolina, Ohio, Tennessee
and Texas.  The Company recently completed an extensive market and consumer
study and, based upon its findings, plans to launch a marketing campaign for its
newly developed consumer brand in September 1998, emphasizing the consistent
year-round quality and superior taste of its tomatoes.  A key component of the
Company's growth strategy is to market its tomatoes in selected new domestic
markets and establish relationships with additional major supermarket chains.
    
  The Company is organized as a holding company and owns all of the outstanding
capital stock of (i) CG Member, Inc., the entity that indirectly operates the
Brush #1, Brush #2, Fort Lupton #1 and Rifle greenhouses, which are the
greenhouses held by the LLC, (ii) Colorado Greenhouse, Inc., the entity that
operates the Estancia and Fort Lupton #2 greenhouses and will operate the Grants
greenhouse upon completion of construction and (iii) CGH Sales, Inc., the entity
that will perform the Company's obligations under the Marketing Agreements
entered into in connection with the Greenver transaction. See "Prospectus
Summary--Company History and Recent Developments--Organizational History" and
"Certain Transactions and Relationships."    

Tomato Industry Overview and Consumer Trends
    
  According to a United States Department of Agriculture report, U.S.
consumption of fresh tomatoes was approximately 19 pounds per person in 1997, or
a total of approximately 5.4 billion pounds.  At an average wholesale price of
$0.33 per pound, the total U.S. fresh tomato market exceeded $1.8 billion at
wholesale.  In 1997, field-grown tomatoes accounted for approximately 92% of
total U.S. tomato market.  The Company believes that a majority of these
tomatoes were "gas green tomatoes" (i.e., picked green and colored via ethylene
gas treatment during shipping), while the remainder were "vine ripe" (i.e., at
least partially ripened in the field before picking).  Greenhouse production,
both domestic and imported and hydroponic and non-hydroponic, accounted for the
remaining approximately 8% of the total U.S. tomato market in 1997.     

  Field-grown tomatoes, particularly gas greens, often exhibit poor taste,
texture and appearance and vary widely in quality.  In addition, as unbranded
commodity products, most tomatoes offer no basis for building consumer awareness
or loyalty.  Supermarket chains also typically experience an unpredictable
supply of tomatoes from a fragmented group of wholesalers and brokers and a lack
of merchandising and promotional support.

  Field tomato growers, particularly in California and Mexico, have attempted to
address the quality gap in recent years by partially ripening tomatoes on the
vine before picking.  The Company believes that although these vine ripe
tomatoes are often superior to gas green products, they still suffer from
substantial inconsistency in quality and supply. Greenhouse producers have
generally succeeded in supplying a better tasting tomato to the market, but to
date are

                                       30
<PAGE>
 
producing in relatively small quantities with limited distribution. In addition,
most hydroponic tomato greenhouses, many of which are located outside the United
States, operate only nine months of the year primarily due to either too few
hours of direct sunlight in the winter or too high daytime temperatures in the
summer.
    
  According to a produce industry trade journal, chain supermarkets account for
approximately 62% of all grocery store sales and tomatoes are one of the top
five items in sales volume in grocery store produce departments.  According to
industry sources, consumers would purchase tomatoes more often if they were of
higher quality.     

  Supermarket produce departments, similar to most other departments,
increasingly have adopted category management with the goal of maximizing
overall profitability for the department based on a better  understanding of
sales patterns and margins by individual items.  This has encouraged produce
managers to ally themselves with suppliers capable of offering both high
quality, year-round supply or produce and branded products, where possible, to
build consumer loyalty, command premium prices on a consistent basis and be
tracked by the supermarket's scanning and inventory systems.

  The past two decades have witnessed widespread growth in consumer demand for
higher quality foods.  This trend has resulted in the emergence of natural,
minimally-processed and preservative-free alternatives in most major food
categories, the growth of the specialty and natural foods retail sector and the
emergence of higher priced, superpremium segments in many categories, including
juice, beer, ice cream and coffee.  In the produce sector, this trend has
resulted in a demand for increased freshness, better taste and more variety and
has led to consumer demand for high-quality branded produce, such as packaged
salads and pre-cut vegetables.  As a result, the Company believes that the
potential market for superpremium branded tomatoes is very broad because
substantial numbers of consumers are willing to pay a premium over the price of
field-grown tomatoes, especially in the winter months, for the improved taste,
appearance, consistency and quality of greenhouse tomatoes.

Company Strengths

  The Company believes that it is uniquely positioned to address the quality and
supply issues of both consumers and the retail trade with a superpremium branded
tomato developed through an integrated hydroponic greenhouse production model
that yields a consistent high quality product with a year-round supply. The
Company's key competitive strengths include:

  Consistent Quality Superpremium Tomatoes on a Year-Round Basis. The Company
has established a reputation as a consistent supplier of high quality, branded
superpremium tomatoes. The Company's greenhouse locations in Colorado and New
Mexico are characterized by an optimal combination of direct sunlight and
moderate summertime temperatures, which provide it with the ability to grow
high-quality tomatoes on a year-round basis.  Commencing in November 1998, the
Company will begin marketing Greenver's tomatoes.  This will provide the Company
with a greater supply of tomatoes from November through April, when domestic
supply is generally at its lowest and prices are typically at their highest.

  Direct Relationships with Major Supermarket Chains.   The Company sells
directly to several of the nation's largest supermarket chains, including
Albertson's, Ingles, King Soopers, Kroger, Lucky's, Meijer and Safeway.  These
direct relationships enable the Company to: (i) retain control over the
distribution process; (ii) establish a "non-commodity" consumer branding
approach to marketing; (iii) differentiate itself through superior customer
service; and (iv) improve margins by eliminating unnecessary middlemen.

  Technical Expertise.  The Company's advanced growing techniques enable it to
produce consistently high-quality tomatoes on a year-round basis.  The Company's
greenhouses are managed by teams of senior growers, principally recruited from
European countries, with expertise in the latest greenhouse and hydroponic
technology.  These senior growers train junior growers to assure that the
Company will have the expertise necessary for its planned expansion. Forty of
the Company's production acres have been constructed, and 20 acres are being
constructed, using a state-of-the-art model designed to enhance growing
conditions and  improve production yield.  The Company also has installed an
integrated management information system, which allows it to monitor closely all
aspects of the plant production, packaging and selling process.

Growth Strategy

  The Company's objective is to strengthen its position as the largest U.S.-
based producer and marketer of high quality greenhouse tomatoes and to increase
sales.  Key elements of the Company's strategy to achieve this goal include:

  Aggressively Develop Consumer Brand Identity.  To capitalize on the regional
success of the Company's branding strategy, in September 1998, the Company plans
to introduce a marketing campaign targeting additional domestic markets with its
newly developed consumer brand.  This campaign will include both trade and
consumer advertising and point-of-sale promotions emphasizing the consistent
year-round availability and superior taste of the Company's tomatoes.  The
Company believes that its branding strategy also may facilitate its future
introduction of other superpremium greenhouse produce.

  Expand Production Capacity. The Company's strategy is to expand production
capacity to meet the increased consumer demand for consistent, high-quality
tomatoes on a year-round basis. The Company is currently constructing a 20-acre
hydroponic greenhouse facility in New Mexico and plans to construct six
additional 20-acre hydroponic greenhouses over the next three years at sites
that provide optimal micro-climatic conditions of sunlight and temperature. The
Greenver marketing arrangement will provide the Company with a greater supply of
tomatoes from November through April, when domestic supply is generally at its
lowest and prices are typically at their highest.
    
  Broaden Retail Distribution.  Most major retailers seek a primary supplier for
each produce category that is capable of delivering both uniform quality and
consistent year-round supply.  The Company believes that by offering retailers
and consumers a high quality product with a consistent year-round supply, it can
become the primary year-round tomato supplier of choice for many major
supermarket chains.  The Company's variety of product sizes and grades and
customized packaging capabilities also provide significant flexibility to retail
chains when offering tomato products to consumers.  The Company's expertise in
conducting marketing programs can assist these retailers in developing consumer
awareness and brand loyalty.  See "--Marketing and Sales."     

Products

  The Company's current product line consists of traditional beefsteak tomatoes
of both the Truss and Bliss varieties and Tradero vine-cluster tomatoes.  These
tomatoes are distinguished by their superior taste over most field-grown
tomatoes, and their appearance, texture and nutritional value.  The Company
believes that by using greenhouse technology to regulate and enhance
environmental conditions, it achieves consistent quality tomatoes and minimizes
production seasonality.  Currently, the Company's tomatoes are sold in display
pack singles, consumer pre-packs and on-the-vine packages.

  Superpremium display pack singles.  The Company hand selects its largest
  superpremium beefsteak tomatoes, sorts them into three sizes, Large,
  ExtraLarge and MaxiXLarge, and ships them to supermarket customers in
  specially packaged black display trays for individual sale.  Each tray weighs
  15 pounds and contains between 18 and 45 tomatoes, depending on their size.
  To increase consumer brand awareness, each tomato is labeled with the
  Company's name and logo.

  Consumer pre-pack.  The Company packages its smaller superpremium tomatoes in
  groups of three, four or six.  The Company's pre-packs feature a distinctive
  consumer package, which can be customized to meet the requirements of
  individual supermarket customers.

  On-the-vine.  The Company's Vine Cluster Gourmet Tomatoes are of the Tradero
  variety and consist of at least three blemish-free tomatoes attached to the
  vine and packaged in a mesh bag.  The Company ships the mesh bags of on-the-
  vine tomatoes in trays that weigh 11 pounds.  The Company generally is able to
  price this product at a 30% premium to its other superpremium tomatoes.

  Standard grade display pack singles.  Most of the Company's standard grade
  tomatoes are USDA #1 quality or better, but less than the Company's
  superpremium grade.  These tomatoes are shipped to customers in specially
  packaged 15 pound white display trays for individual sale.  The Company also
  ships a small number of USDA #2 quality tomatoes, which are of a lesser
  quality than USDA #1 but are sold by some retail chains.

  The Company grades all of its tomatoes as either superpremium or standard
grade based on its own specifications. The Company defines superpremium tomatoes
as those that are free from all scars, cuts, bruises, blotchy ripening and
translucent or soft conditions, are round with a smooth shoulder, have no flat
spots or indentations, have a well formed, smooth blossom end with an
indentation of no more that 1/16", with the calyx (the stem) still in place and
with no more than minor "russeting" (the micro cracking of the skin around the
calyx).  Standard tomatoes are those tomatoes that vary from the superpremium
specifications for the calyx, scarring, blemishes and russeting.  The Company
permits only a small number of tomatoes with these minor defects per tray of
standard tomatoes.  Because a tomato's color identifies its level of development
and ripeness, both superpremium and standard tomatoes are sorted based on color
so that all tomatoes from the same box will ripen uniformly.

  The following table sets forth information concerning the Company's products
during the first quarters of 1997 and 1998.

(1) Prevailing market prices for tomatoes are highly seasonal, and typically are
    at their highest levels in the first quarter.  Accordingly, the Company's

    "Management's Discussion and Analysis of Financial Condition and Results of
    Operations--Seasonality; Quarterly Results."

Marketing and Sales

  The Company markets most of its tomatoes directly to its supermarket chain
customers.  These direct relationships enable the Company to retain control over
the distribution process, establish a "non-commodity" consumer branding approach
to marketing, differentiate itself through superior customer service and improve
margins by eliminating unnecessary middlemen.  The Company's marketing strategy
has been to create awareness of the Company's tomatoes by supermarket chains on
a regional basis and thereby gain shelf space.  The Company actively
participates in trade shows and advertises in various trade publications to
reach supermarket chains.  In marketing to potential supermarket customers, the
Company emphasizes its high-quality tomatoes and consistent supply, with the
objective of becoming that customer's primary year-round tomato supplier of
choice.  The Company also offers its customers consumer awareness programs, such
as in-store product demonstrations, media advertising and cooperative
promotional programs.
    
  When a supermarket chain first decides to carry the Company's products, the
Company develops a marketing program with the supermarket chain.  The marketing
program sets forth the amount and type of the Company's products the supermarket
chain will carry and provides for various forms of marketing support by the
Company in that customer's market including assistance with point-of-sale
presentation such as arranging for in-store demonstrations and providing
recipes, sale promotion assistance and print and media advertising support.
After the marketing program is in place, each week a Company sales
representative quotes the customer prices for the following week and ensures the
customer's marketing program is satisfied on a weekly basis.  This permits the
customer to keep the freshest tomatoes in stock and gives sufficient lead time
to enable the Company to fill orders.  The sales staff works closely with the
Company's production group to help anticipate and accommodate customer
requirements.  Each tomato or consumer package is labeled with a Price Look Up
("PLU") sticker to facilitate category management by the customer.     

  The Company maintains a sales and marketing staff of six employees at its Fort
Lupton, Colorado headquarters. The Company expects to add several regional sales
offices over the next two years, including one in California in connection with
marketing Greenver's produce.  When Greenver's tomatoes first become available
in November 1998, the Company intends to include them into its standard
marketing activities.

Brand Development

  To strengthen its position as the leading U.S.-based producer and marketer of
superpremium greenhouse tomatoes, the Company will concentrate on promoting
brand recognition and loyalty among consumers by introducing a marketing
campaign in the fall of 1998.  This campaign will target additional markets and
focus on the Company's newly developed consumer brand.  The campaign will
include both trade and consumer advertising and point-of-sale promotions
emphasizing the consistent year-round availability and superior taste of the
Company's tomatoes.  The Company intends also to provide point-of-sale materials
such as product literature and recipes to help consumers distinguish its product
from unbranded tomatoes, as well as discount coupons.  The Company believes that
its branding strategy also may facilitate its future introduction of other
superpremium greenhouse products.

Customers and Product Distribution

  The Company's principal customers are ten major supermarket chains, which
collectively accounted for approximately 79.0% of the Company's net sales in
1997.  The Company's remaining customers are selected regional wholesalers and
brokers who purchase in truckload quantities and distribute to natural food
stores, smaller grocery chains and independent grocers.

  The Company's retail and wholesale customers are concentrated in Colorado,
California, Michigan, North Carolina, Ohio, Tennessee and Texas.  The Company's
leading supermarket chain customers are Safeway (in Colorado), Meijer (in
Michigan), King Soopers (in Colorado), Kroger (in Ohio and Texas), Albertson's
(in California and Colorado), Ingles (in North Carolina and Tennessee) and
Lucky's (in California).  During 1997, sales to Safeway, Meijer and King Soopers
represented 23.5%, 15.3% and 14.0% of the Company's total net sales,
respectively.  No other customer accounted for more than 6.2% of the Company's
total net sales in 1997.  Because a high concentration of the Company's sales
are to a relatively few customers, the loss of one or more major customers could
have a material adverse effect on the Company's results of operations.

  The Company arranges for the delivery of all of its products to its customers
by truck.  The Company owns three and leases two other temperature controlled
tractor-trailers, which it uses for delivery of its products within Colorado.
The Company contracts on a per load basis with independent trucking companies
for deliveries outside Colorado.   The Company will take delivery of Greenver's
produce at a third party cross-docking facility in or near San Diego,
California, from which the produce will be delivered to the Company's customers
by independent trucking companies.

    production in March 1998.
(3) The Estancia greenhouse was completed in August 1997 and began production in
    October 1997.
(4) This greenhouse, which is currently under construction, is expected to be

  Site Selection Criteria.  The Company selects sites for new greenhouse
facilities based on their optimal micro-climatic conditions of sunlight and
temperature, sufficient water supply and a low cost supply of natural gas for
heating. All of the Company's greenhouses are located in Colorado and New Mexico
because these states provide over 250 days of sunshine per year, including ample
sunlight during the winter months, and a moderate summertime high temperature
that permits production during the summer months and reduces greenhouse cooling
costs.  As a result, the Company is able to produce tomatoes on a year-round
basis, unlike greenhouses located in areas where the summer months are very hot
or the winter months do not have sufficient sunlight.

  Design Features of the Company's Greenhouse Model.  The Company's greenhouse
model has been developed and refined over a number of years through the
experience learned in each successive facility.  The first of the Company's
greenhouses that was constructed, Rifle, is only approximately 13.5 acres in
size, is constructed of plastic overlaying a steel truss structure and contains
a non-direct forced air heating system.  Brush #1 is an 18.0 acre plastic
facility, and Brush #2 is a 19.7 acre glass facility.  The Company's three other
greenhouses are 20-acre units, constructed of glass, which has better light
transmission characteristics than plastic, and use direct radiation heating
techniques through hot water pipes directly below the growing canopy.  This
permits the Company to control better the amount of heat necessary for optimal
plant growth.  The Company's newer greenhouses, Estancia, Fort Lupton #2 and the
Grants greenhouse currently under construction, use an improved glass design in
which there are fewer steel trusses to block the light, a roof that is
approximately three feet higher to allow for more heat retention and glass that
is positioned to permit better light transmission.

  The Company believes that its model 20-acre facility provides it with the
optimal balance between the economies of scale that come with a large facility
and a facility of manageable size.  Starting with the Fort Lupton greenhouses,
the Company has constructed two adjacent unitized 20-acre facilities, thus
increasing the economies of scale by permitting shared greenhouse supply areas,
boiler and pump houses, as well as combined packing facilities, while at the
same time retaining the manageability that comes with a 20-acre facility.  The
Company has designed both the Estancia facility and the Grants facility to
permit the construction of adjacent 20-acre facilities, and all future
facilities are expected to use this unitized 20-acre facility model.

  Integrated Hydroponic Greenhouse Production Model.  All of the Company's
greenhouses use the Company's integrated hydroponic production model.
Hydroponics is the cultivation of plants in liquid nutrient solutions.  The
Company's plants are cultivated in rockwool, a porous substrate material made
from volcanic-based rock, which provides significantly more control over the
root environment and allows the Company to manage better the balance of
nutrients required for healthy plant cultivation.  This closely monitored
environment allows tomatoes to receive the benefits from sunlight, with the
additional advantage of computer-controlled temperature and humidity required
for strong, healthy

                                       35
<PAGE>
 
plants. Hydroponic production also minimizes the variables that cause
inconsistency in product and yield and isolates the plants from soil-born pests
and diseases.

  The development cycle of a tomato plant is approximately three months from
seed to the first harvest of fruit. Thereafter, the Company's plants usually
yield tomatoes for a period of four to five months.  Propagation, the tomatoes'
nursery stage, begins at a separate third-party greenhouse.  After approximately
six weeks at the propagation center and approximately three or four days prior
to the appearance of the first flowers, the plants are shipped to the Company's
greenhouses.

  Upon arrival at the greenhouse, plants are placed in their permanent location
on rockwool mats.  Most greenhouse environments result in downtime of
approximately three months between the final harvest of the old crop and the
first harvest of the new crop.  To ensure continuous year-round production of
tomatoes without wasting greenhouse space, the Company places young plants
adjacent to mature tomato plants nearing the end of their production.  This
process, called "interplanting," uses techniques refined by the Company.   As a
result, the Company's first harvest from the new plants usually occurs within
one to three weeks after the prior crop's final harvest.

  Each plant is isolated initially from the rockwool mats using a styrofoam tray
in order to prevent the roots from penetrating the mats prematurely.  An
individual dripper hose is inserted into each rockwool block, and the plants are
attached to strings to maintain upward growth of the vines.  At the same time,
bumble bees are introduced into the newly planted areas for pollination
purposes.  Hives, which contain nectar for the bees, are placed on shelves at
the end of the greenhouse rows.  Two weeks after introduction to the greenhouse,
the styrofoam trays are removed and the dripper hoses are run through the blocks
into the mat itself, allowing each plant's root system to spread throughout the
mat.

  Regular plant maintenance includes clipping and pruning, adding truss
supports, cluster pruning to maintain the desired number of tomatoes per truss
and regular "deleafing," a process in which leaves are removed from the bottom
of the plants as they grow taller to direct the energy upward toward the
producing part of the plants.  As the plants grow, they are periodically lowered
by unwinding string from reels attached above each vine to keep the top of the
plants at the optimum height for plant growth and to provide easier access to
the producing part of the vines.   As a result of the Company's production
process, only about 5% of the tomatoes grown by the Company are discarded.
These discarded tomatoes are either sold to local farmers as animal feed or
thrown away.

  The Company's computer system monitors every aspect of the plant's life,
including acidity and salt solution percentages.  The climate in the greenhouse
is also precisely controlled for temperature, CO\\2\\ content and humidity.  The
greenhouses have a  daytime growing temperature of between 70 and 80 degrees
Fahrenheit and a humidity level of 70%. At night, the temperature is dropped to
between 55 and 60 degrees Fahrenheit.  During the summer months, the greenhouses
are ventilated by interior or exterior evaporative cooling.  In cooler months,
hot water is circulated throughout the greenhouse through pipes between each row
of plants.  These pipes also serve as rails for the picking carts.  The Company
obtains the heat for the Brush #1, Brush #2, Fort Lupton #1 and Rifle
greenhouses from the adjacent cogeneration plants and has backup boilers in the
event of a shut-down of the power plants.  Stand-alone boilers employing natural
gas are used to provide hot water at the Fort Lupton #2 greenhouse and the New
Mexico facilities. The air quality of each greenhouse also is constantly
monitored and, when necessary, CO\\2\\ is released into the greenhouse
environment because CO\\2 \\is essential for plant growth.  In the stand-alone
facilities, CO\\2\\ is obtained from the water heating process, and in the
cogeneration greenhouses, the Company purchases CO\\2\\.  The Company also
monitors the outside environment, including temperature, solar radiation, wind
speed and wind direction, to help gauge the heating requirements of the
greenhouse and the amount of sunlight each greenhouse receives.

  Harvesting and Packing.  Ripe tomatoes are picked by hand and placed onto
carts.  The distance to market determines at what stage of ripeness tomatoes
will be harvested.  Each individual harvester enters information about the
number of trays of tomatoes picked in each row into a key pad linked to the
Company's computer.  The trays are loaded onto pallets and transported to a
sorting, packing and shipping facility (the "pack houses").  The Company
currently has pack houses at Brush and Fort Lupton.  The Brush pack house
handles most of the tomatoes from the two Brush greenhouses.  The Fort Lupton
pack house packs the remaining tomatoes from Brush, as well as the tomatoes from
the Estancia, Rifle and the two Fort Lupton greenhouses. The Company has
constructed a pack house at its Estancia greenhouse and intends to commence
operation of this pack house upon completion of the Grants greenhouse.  The
Estancia pack house will pack all of the Company's tomatoes grown in New Mexico.

                                       36
<PAGE>
 
  After being washed and dried, the tomatoes are hand sorted according to size.
About 80% of the tomatoes produced by the Company are in the MaxiXLarge or
ExtraLarge categories, and all superpremium tomatoes of these sizes are packed
by hand into 15 pound, single-layer trays according to color stage or ripeness
and size.  Each superpremium tomato is labeled with the PLU sticker, and each
tray is marked with a code indicating the site where the product was grown and
the date of packing.  Approximately 11% of the Company's tomatoes are standard
grade display pack singles, which are packed by hand into 15 pound trays.  All
remaining tomatoes not sold as display pack singles are sent by conveyor belt to
a pre-pack system where they are packaged into three, four or six-count retail
packs.  The Company's on-the-vine tomatoes are packaged in net bags of three to
five tomatoes with the vine still attached and shipped in 11 pound trays.  After
packing, the tomatoes are loaded onto trucks for shipment.

  Quality Control Programs.  Managing the health of the Company's tomato plants
is critical to maintaining the required production levels.  Following the
Company's pest and disease related production problems in 1997, the Company
instituted a number of quality control monitoring systems to provide an early
warning against pest and disease problems.  The growers in each greenhouse
complete a "cultural table" regarding the condition of the plants on a weekly
basis.  The cultural table is based on evaluations of sample plants throughout
each greenhouse and measures plant development, including the number and width
of the leaves, the number of flowers per plant, the diameter of the plant stem,
the number of tomatoes per stem and the size development of the tomatoes.
Sample leaves are sent to laboratories weekly for leaf analysis to determine the
nutrient content and identify any deficiencies.  Any suspect plants are also
leaf sampled for disease identification.  These data give the Company's senior
growers information that should indicate early deficiencies in the plant
production cycle and the opportunity to compare the current crop to historical
data from previous crops.

  The Company also monitors the rooting environment of its plants by testing
water quality on a daily basis and determines the quantity of water used by
measuring the volume of water for each row of plants and the volume of water
that drains off each row.  Irrigation drainage water is also monitored to
determine the plant's chemical and nutrient intake, is then sterilized by ultra-
violet light, with any necessary nutrients added, and is recirculated to the
plants, thereby conserving valuable materials and water.  By monitoring
irrigation water, senior growers can determine whether each row of plants is
receiving and utilizing the proper volume of water and nutrients.

  The Company instituted a number of safeguards against pests following the 1997
production problems.  These include pest trap monitoring cards throughout the
greenhouses that allow employees to count the number and variety of insects in
each facility, as well as visual crop monitoring for pests.  The Company
utilizes a biological pest control management system, whereby plant-friendly
predator insects who feed upon the unwanted pests are used to control common
greenhouse insects.  As a result, some level of harmful pests, such as
whiteflies, will be found in the greenhouses in order to feed the beneficial
pest population.  In addition, pollination is performed by bumble bees that
require an insect friendly environment.  If it is determined that biological
controls are not adequate to maintain the health of the plants, chemicals may be
applied to maintain the proper balance between these beneficial and harmful
pests. Because of the bees, however, the use of deleterious chemicals must be
minimal.

  The Company believes that these quality control programs will provide it with
sufficient early warning signs to enable it to react to most production threats
in a timely fashion, thereby minimizing the risk of a recurrence of the problems
that the Company experienced in 1997.  There can be no assurance, however, that
these programs will be sufficient to control all possible disease or pest
problems.

  Steps Taken to Combat 1997 Production Problems.  During 1997, the Company
experienced mechanical problems, pest and disease infestations and a flood that
significantly reduced production during parts of the year in three of the
Company's greenhouses.  In the Brush #1 greenhouse, a root disease reduced
tomato production by approximately 18.9% during the first and second quarters of
1997.  This was followed in the third quarter by an invasion of thrips (an
insect) through the greenhouse's unscreened ventilation system, which carried a
virus from adjacent agricultural field crops. This virus reduced plant
populations as well as tomato volumes and size, resulting in a decline in the
Company's average sales price per pound.  During the third quarter of 1997,
Brush #2 was also affected negatively by the same root disease that affected
Brush #1 and was infested with a large population of whiteflies.  This led to
the Company's decision to pull out its entire existing crop at Brush #2 and
disinfect the greenhouse at the beginning of the fourth quarter of 1997.  At the
end of the first quarter of 1997, the Fort Lupton #1 greenhouse experienced a
mechanical failure in its irrigation system, followed by a flood at the end of
July that required the Company to pull out the entire crop to avoid an outbreak
of root rot common in water damaged crops.  As a result of all of these
problems, the Company experienced 

                                       37
<PAGE>
 
    
approximately a 13% decline in total production sold in 1997 compared to 1996,
despite the addition of production from the 20-acre Estancia greenhouse in
October 1997.     

  Following the production shortfalls of 1997, a complete review of the
Company's management structure, experience, operating procedures and expertise
was undertaken and significant changes were made.  The Company believes it has
remedied the problems that lead to mechanical malfunctions and has used the
experiences to update its existing greenhouses and better design future
greenhouses.  The Company hired a new senior management team that implemented
various initiatives and quality control measures to reduce the likelihood of
similar problems occurring in the future and obtained improved insurance
coverage.  The Company has direct damage insurance covering both property damage
to its greenhouses and lost profits and was able to recover $802,000 as a result
of the damage from the flood.  This recovery represented approximately one-half
of the lost sales that resulted from the flood, which subsequently caused
management to obtain new insurance coverage.  Management believes that its new
insurance policy will more adequately protect it in the event of a catastrophic
loss.  In addition, because the Company had two of its four greenhouses out of
production during the fourth quarter of 1997 due to various pest and mechanical
problems, the Company was able to modify its packing operations to consolidate
pack houses.  To effect this consolidation, the pack house at Fort Lupton was
enlarged and new flow-through racking was installed to permit the packing of
tomatoes from the Fort Lupton #2 greenhouse as well as some of tomatoes from the
Brush greenhouses.

  Raw Materials Used in Production.  The Company obtains the raw materials
necessary for the production of its tomatoes, including rockwool, tomato
seedlings, CO\\2\\, bees, fertilizer, insecticides and packaging materials from
various suppliers.  These suppliers include Grodania A/S (rockwool), Cherry
Creek Growers, Inc. (tomato plant seedlings), Praxair, Inc. (CO\\2\\), Koppert
Biological Systems, Inc. (bumble bees), Van Waters and Rogers, Inc. (fertilizer
and insecticide) and Willamette Industries, Inc. (packaging materials).
Whenever possible, the Company enters into annual agreements for these raw
materials that set the price for the year and then orders materials on an as
needed basis.  The Company currently obtains its seedlings from a single source.
Loss of this source could result in a decrease in the Company's tomato
production until this supplier can be replaced.  With respect to its other raw
material suppliers, the Company believes that its relationship with these
suppliers generally is good.  If the Company were to lose any one or more of
these raw material suppliers, the Company could contract for its raw materials
with several other suppliers on terms the Company believes would be comparable.

Greenver Transaction and Marketing Agreement
    
  In May 1998, the Company acquired a 25% equity interest in Greenver for $4.0
million.  Greenver has 88 acres of non-hydroponic greenhouses under production
in Baja, Mexico, growing tomatoes and some sweet peppers.  The proceeds of the
Company's investment in Greenver are being used by Greenver to construct an
additional 87 acres of non-hydroponic greenhouse facilities, which are expected
to commence production by November 1998.  Although Greenver's tomatoes are of
comparable quality to the Company's tomatoes, the Company will provide Greenver
with technical assistance to increase Greenver's production yield and the
Company intends to introduce hydroponic growing techniques to at least some of
Greenver's facilities.  As a result of its equity interest, the Company is
entitled to 25% of all dividends, if any, distributed by Greenver.     
    
  As part of the Greenver Transaction, the Company entered into an exclusive
marketing agreement (the "Marketing Agreement"), whereby the Company obtained
the exclusive right, but not the obligation, to market in the United States,
Canada and Europe all export-quality tomatoes produced by Greenver, for which
the Company will receive a 10% commission on total sales revenue less
transportation costs from San Diego to the point of destination. The Company
intends to exercise this right for all of Greenver's produce that is of a
quality and grade consistent with the Company's domestic tomatoes. The Company
intends to have a representative present at Greenver's facilities to select the
products to be sold under the Marketing Agreement. The agreement prohibits
Greenver from selling its export-quality products in the United States, Canada
or Europe except through the Company. Because of the favorable growing
conditions during the winter months in Baja, Mexico, as well as improved growing
techniques the Company is introducing to the Greenver facilities, the Company
anticipates that the Greenver Transaction will provide it with up to 18 million
pounds of tomatoes during the November 1998 through April 1999 growing season, a
time of year in which production from the Company's existing facilities
declines. During these months, the Company has historically received the highest
prices for its tomatoes.    

  Under the Marketing Agreement, the Company will never take title to the
produce but has the right to determine the manner and terms of sales, so long as
the price is not less than the Company receives for tomatoes of equivalent
quality

                                       38
<PAGE>
 
grown by the Company. The agreement has a term of ten years, subject to
termination by Greenver at the end of five years if certain criteria related to
the Company's marketing of Greenver's tomatoes have not been met. If the
agreement is then terminated, the Company has the option (i) to require the
other Greenver shareholders to repurchase the Company's equity in Greenver for
the higher of market value at the time of repurchase or $4.0 million, or (ii)
the right to acquire a 50% equity interest in any company formed by Greenver to
market its products in the United States, Canada or Europe.
    
  Under the Marketing Agreement, the Company must reimburse Greenver weekly for
Greenver's production and transportation costs for tomatoes the Company received
in the previous week.  In addition, the Company must remit to Greenver monthly
the amount of sales of Greenver tomatoes less costs previously borne by the
Company, the Company's sales commission and any transportation costs from San
Diego incurred by the Company.   The Company is responsible for all advertising,
marketing and promotion expenses and the third party cross-docking facility
fees, and bears the risk of uncollectible accounts receivable.  All products
sold under the Marketing Agreement will be packaged in cartons and labels
approved by the Company and will be marketed with the Company's tomatoes.  The
Company has not yet determined whether it will market Greenver's tomatoes under
its own trademarks.  Greenver will warrant to the Company all products sold
under the Marketing Agreement to be in good and marketable condition and
harvested, handled, packed and shipped in accordance with standards set by the
Company and U.S. regulatory agencies.     

Research and Development
    
  The Company is engaged in ongoing testing at its Brush, Fort Lupton and Rifle
greenhouses of various varieties of tomatoes to determine if they could improve
the Company's production yields.  The Company tests these tomato varieties for
their maturation period, resistance to disease, the size and quality of the
tomatoes and the tomatoes' shelf life, taste and adaptability to seasonal
changes in light.  The Company's growers conduct these tests initially as
varietal trials, where a few plants of several different varieties are placed
throughout a greenhouse and observed.  If a new variety shows promising
characteristics, the Company conducts a commercial trial where the new variety
is planted on a larger scale, with performance results compared to the Company's
existing tomato varieties.  To date, the Company has selected  two of these new
varieties of tomatoes for regular production on a seasonal basis, a Grace
variety for winter production and an as yet unnamed variety for summer
production.  To date, the Company's research and development expenditures have
not been material.     

  The Company currently devotes a total of approximately 10 acres at its Brush,
Fort Lupton and Rifle greenhouses to research and development.  The Company and
Greenver have also begun testing other superpremium produce at Greenver's
facilities in Mexico.  There are, however, a limited number of vegetables that
can be grown economically in the greenhouse environment.

Management Information System

  The Company operates an integrated management information system with real-
time software that connects its corporate facility with its greenhouses through
a wide area network, augmented by a local area network at each greenhouse.  This
system enables the Company to monitor every aspect of its operations, including
tomato plant production and forecasting, employee productivity, inventory
management and customer information.  The Company has installed computer hookups
at various locations throughout each greenhouse that allow the greenhouse
employees to enter information about the maintenance and harvesting activities
for a particular row of tomatoes.  This allows the Company to monitor the output
of each individual worker and the crop, as well as the workers in the pack
houses.  The system also provides the Company with  daily inventory control
information, such as the number of pounds of tomatoes harvested.  With these
data, the Company is able to update its eight week production forecasts on a
weekly basis so that its sales staff knows how much inventory will become
available.  The management information system also provides the Company with the
number of pounds of tomatoes that have been packaged and palletized for
shipping, which allows the Company to compile a daily shipping schedule to track
when each box was packed and the age of the Company's inventory, thus limiting
product spoilage.  During 1999, the Company expects to implement an electronic
data interchange system for use with its supermarket customers.

  All of the Company's accounting information and information regarding
materials usage and purchase orders are included in the system, as well as all
information about the Company's sales orders.  The Company is then able to
prepare and track customer information regarding the amount and type of tomatoes
purchased on a weekly and monthly basis. 

                                       39
<PAGE>
 
The Company believes that its management information system has allowed it to
increase productivity and efficiency by providing management with the essential
information in a concise format. The Company believes that its management
information system has sufficient expansion capacity for the Company's planned
growth for at least the next two to three years.

Competition
    
  The Company believes that the principal competitive factors affecting its
market include product consistency, quality and price, effectiveness of sales
and marketing efforts and company reputation.  The Company competes in the
tomato market both with other hydroponic greenhouse tomato producers and with
commercial producers of field-grown tomatoes, both gas green (in which the
tomatoes are picked green and colored via ethylene gas during shipping) and vine
ripened.  Field-grown tomatoes originate primarily from Florida, California or
Mexico, depending on the season.  During 1997, field-grown tomatoes accounted
for approximately 92% of total U.S. fresh tomato production, while hydroponic
greenhouse tomatoes, both domestic and imported, accounted for the remaining
approximately 8%.  Most field-grown tomatoes are sold at wholesale at
approximately one-half the price of the Company's greenhouse grown tomatoes.
During the local growing season, typically late summer, the Company also
competes with home- and locally-grown tomatoes.  The Company competes with
field-grown tomatoes on the basis of overall quality, including taste, texture
and appearance, brand recognition and point-of-sale presentation.  Field-grown
tomato competitors include numerous local and regional growers as well as a
number of major grower-shippers in the United States and Mexico, including
DiMare (Florida and California), Gargiulo (Florida and California), R&B Packing
(Mexico) and Meyers (Mexico).  These major grower-shippers ship substantially
more tomatoes than the Company, have longer standing relationships with various
retailers and wholesalers and have greater financial resources than the Company.
     
    
  The Company's competition in the hydroponic greenhouse tomato market comes
from various domestic and foreign hydroponic greenhouse tomato producers and
cooperatives, including domestic producers Eurofresh (with greenhouses in
Arizona), Village Farms (with greenhouses in New York, Pennsylvania, Texas and
Virginia) and BC Hothouse (with greenhouses in California). The Company
estimates that worldwide, hydroponic greenhouse tomatoes currently originate
from approximately 700 acres in the United States (including the approximately
111 acres owned by the Company), approximately 900 acres in Canada and an
estimated aggregate of more than 5,000 acres in Belgium, France, Israel,
Morocco, The Netherlands and Spain. Some portion of the foreign produced
hydroponic tomatoes are sold in the United States. Most of these sources produce
high-quality tomatoes superior in taste, texture and appearance to most field-
grown tomatoes and generally comparable in quality to the Company's 
tomatoes.     

Facilities

  The Company owns the Estancia and Fort Lupton #2 greenhouses and will own the
facility but not the land under the Grants greenhouse.  The Company operates the
Brush #1, Brush #2, Fort Lupton #1 and Rifle greenhouses pursuant to Operating
and Management Agreements, which are functionally equivalent to subleases.  Each
of these four leased greenhouses was constructed as part of a cogeneration power
plant that is a "Qualifying Facility" under the terms of the Public Utility
Regulatory Policy Act of 1978.  Each of these cogeneration facilities was
financed using a "project financing" structure that utilizes one single-purpose
entity to own the power plant and another to act as lessee of the greenhouse
from the first entity.  Each greenhouse lessee in turn acts as sublessor to the
Company under an Operating and Management Agreement.

  The Estancia, Fort Lupton #2 and Grants greenhouses are located on parcels of
160, 26.72 and 70 acres, respectively.  The Company's four leased greenhouses
cover an aggregate of approximately 71 acres, and each is operated as part of a
cogeneration project, with the greenhouses using the surplus heat from the power
plants to heat the water used to heat the greenhouses.  The Company's owned
greenhouses, Estancia and Fort Lupton #2, are, and all future facilities,
including the Grants greenhouse currently under construction, are expected to
be, stand-alone facilities with their own natural gas-fired boilers for heat
generation.  Non-cogeneration greenhouses typically have higher costs to
generate heat but lower CO\\2\\ costs because the CO\\2\\ can be extracted from
the combustion process that generates the heat.
    
  The remaining terms of the Operating and Management Agreements are four, six,
11 and 21 years for the Rifle, Brush #1, Brush #2 and Fort Lupton #1
greenhouses, respectively.  Annual rent incurred during 1997 was $500,000 for
Rifle, $853,099 for Brush #1, $1,042,191 for Brush #2 and $1,033,802 for Fort
Lupton #1.  The Company is required to maintain rent reserves with the owners of
the greenhouses (which are in turn pledged by the owners to their lenders)
     

                                       40
<PAGE>
 
    
of one year's rent for the Fort Lupton #1 and Brush #2 greenhouses and one-half
year's rent for the Brush #1 greenhouse. Of the leased facilities, the Company
has to pay for its heat requirements only for Fort Lupton #1, which totaled
approximately $154,000 in 1997.     

  The Company currently has pack houses at Brush and Fort Lupton.  The Brush
pack house handles most of the tomatoes from the two Brush greenhouses.  The
Fort Lupton pack house packs the remaining tomatoes from Brush, as well as the
tomatoes from the Estancia, Rifle and the two Fort Lupton greenhouses.  The
Company has constructed a pack house at its Estancia greenhouse and intends to
commence operation of this pack house upon completion of the Grants greenhouse.
The Estancia pack house will pack all of the Company's tomatoes grown in New
Mexico.

  In May 1998, the Company commenced construction of the 20-acre greenhouse
facility in Grants, New Mexico on a site leased from the City of Grants pursuant
to a 60-year ground lease (the "Grants Lease").  Construction is expected to be
completed by November 1998.  The Company's equity portion of the construction
cost is expected to be approximately $5.0 million, with the remaining cost
financed under a construction loan with Farm Credit, which will be converted to
a 10-year term loan upon completion of construction.  The Grants Lease requires
that in lieu of rent, the Company must employ approximately 60 full-time people
from the twelfth through the sixtieth month and approximately 110 people
thereafter.  The Company anticipates that it will be able to meet the 60
employee requirement with the proposed 20-acre facility and the 110 employee
requirement with an additional 20-acre greenhouse facility expected to be
constructed and in operation prior to the sixtieth month.

  The Company intends to use a portion of the net proceeds of this offering to
fund some or all of the cost of constructing up to six additional 20-acre
greenhouse facilities, one of which is expected to be adjacent to the greenhouse
in Estancia and a second adjacent to the greenhouse in Grants.  The Company
currently anticipates that construction of two of these facilities will commence
by mid-1999.  These locations have been chosen because of the high number of
sunny days, particularly during the winter months, and the relatively high
elevation, which provides cooler summer temperatures, both of which are
climatological factors beneficial to greenhouse tomato production.  The Company
believes that these sites have access to sufficient quantities of water and
natural gas for the new facilities. These facilities, and all future facilities,
are expected to incorporate the Company's unitized 20-acre integrated hydroponic
greenhouse production model.  No sites have been selected for the remaining four
facilities, but the Company will select only those sites that provide micro-
climatic conditions of sunlight and temperature similar to those of its existing
greenhouses.

Employees and Training

  As of May 31, 1998, the Company had 563 employees, all of whom were full time,
including 474 in growing and packaging, six in marketing and sales and 83 in
administration.  Each 20-acre greenhouse requires approximately 60 production
and pack house employees.  The Company believes its relationship with its
employees is good.  None of its work force is currently unionized.

  Each 20-acre greenhouse is operated under the direction of a senior grower,
assisted by two junior growers, each responsible for a 10-acre section, and two
assistant growers, each responsible for five acres.  As the junior and assistant
growers gain experience, they are given responsibility over more acreage.  All
senior growers participate in a weekly conference call to discuss production
issues at the greenhouses, and meet once a month to walk through a different
greenhouse.  The Company believes that these meetings provide a quality check on
each greenhouse's operation as the senior growers provide critiques of the
greenhouse being reviewed.  The Company's team of senior, junior and assistant
growers is intended to provide the Company with a sufficient number of qualified
growers to staff properly the planned additional greenhouses, as well as to
assure that each greenhouse's plants receive the necessary inspection on a
regular basis.  To date, turnover among the Company's growers has not been
significant.  In 1997, the Company began to grant stock options to its senior
growers as an added incentive.

  All other greenhouse and pack house employees are trained by the Company.  To
date, the Company has been able to employ a sufficient number of people to staff
its operations.  While there is some seasonal fluctuation in the Company's
employment levels for its non-administrative positions, the Company offers year
round employment to most of its agricultural workers.  The Company believes that
this, coupled with an average starting wage of $6.00 per hour, gives it an
advantage in attracting and retaining capable and loyal agricultural workers.

Risk Management; Insurance; Legal Proceedings

  The Company is subject to various risks in operating its business,  including
catastrophes such as floods, tornadoes, hail storms, severe winds or rain or
other adverse weather events, as well as other risks related to its production,
such as the loss of water or heat to the greenhouses or a mechanical failure in
the heating, ventilation or irrigation system. To mitigate against these risks,
the Company has direct property damage and business interruption insurance
coverage. The Company's prior insurance policy only covered a loss that resulted
from direct damage to the tomato plants and did not cover indirect damage or
consequential losses.  Because the flood that occurred in 1997 at Ft. Lupton #1
was not deemed to have directly damaged all of the plants, the loss of the
plants was not totally covered and none of the Company's consequential losses
were covered.  In December 1997, the Company obtained new insurance policies
covering both direct and indirect damage to the tomato plants and consequential
losses.  The deductibles for this policy vary between $5,000 and $50,000 per
incident.  The Company also maintains insurance including workers compensation,
accidental product contamination and product tampering, third-party damage,
liability and bodily injury coverage.
    
  The Company is also subject to uninsured risks related to plant diseases and
pest infestations.  See  "Risk Factors--Risk of Loss to Crop from Pests or
Mechanical Failures."   To protect against a number of production risks, the
Company has established early warning systems to alert it to the possibility of
events that could result in a loss of production.  The early warning systems
include a 24-hour electronic monitoring system of the temperature, humidity,
CO\\2\\ and water quality in each greenhouse, with alarms for growers and
maintenance personnel in their homes that sound whenever one of these factors
reaches a critical level, pest trap cards that permit the Company to monitor the
number and type of pests that circulate throughout the greenhouse and weekly
leaf analysis to test for viral or bacterial contamination of the tomato plants.
To protect against a loss of heat or water to a greenhouse, the Company has
backup systems at each greenhouse that can utilize either natural gas or diesel
fuel, as well as short term water storage capabilities.      

  The Company currently is not a party to any material legal proceedings, nor is
it currently aware of any threatened material legal proceedings.  From time to
time, the Company may become involved in litigation relating to claims arising
out of its operations in the normal course of its business.

Government Regulation

  The manufacture, processing, packaging, storage, distribution and labeling of
food products are subject to extensive federal, state and foreign laws and
regulations.  In the United States, the Company's business is subject to
regulation by the Food and Drug Administration ("FDA"), the United States
Department of Agriculture ("USDA") and various state and local agricultural and
public health authorities.  Under the Federal Food, Drug and Cosmetic Act,
administered by the FDA, the Company is subject to a comprehensive regulatory
scheme governing labeling, packaging and food safety. This includes regulations
concerning the packaging process, quality assurance programs and claims of
health benefits of food products.  In addition, the FDA enforces the Public
Health Services Act, which authorizes regulatory activity necessary to prevent
the introduction, transmission or spread of communicable diseases.  The FDA and
USDA regulators charged with enforcing these laws and regulations have broad
powers to protect public health, including the power to inspect produce and the
Company's facilities, to order the shut down of a facility or the suspension of
delivery of the Company's produce, as well as the power to impose substantial
fines.

  The U. S. Immigration and Naturalization Service ("INS") conducts periodic,
random inspections of the Company's greenhouses to ensure that all immigrant
employees have proper documentation.  The Company attempts to confirm the legal
status of all applicants as part of its normal hiring procedures.  The INS has
the power to impose substantial fines on the Company if it finds any
undocumented employees and require the Company to discharge such employees, in
which case the Company would suffer the loss of a portion of its labor force.
The Company also is subject to various federal and state regulations relating to
workplace safety and worker health, including the Fair Labor Standards Act,
Occupational Safety and Health Act and laws and regulations governing such
matters as minimum wages, overtime and working conditions.

  The Company is subject to various federal, state and local environmental
regulations.  These include the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980, as amended; the Resource Conservation
and Recovery Act, as amended; the Federal Water Pollution Control Act; the Clean
Air Act; the Hazardous Materials Transportation Act; the Toxic Substances
Control Act; and their state and local counterparts and equivalents. 

                                       42

Most of the Company's greenhouses discharge wastewater effluent into municipal
waste treatment facilities, in some cases at levels that may require the Company
to pay wastewater surcharges to municipal water treatment authorities. Some of
these authorities have the contractual right to require the Company to limit the
level of discharges, construct pretreatment facilities or take other action to
reduce effluent discharges in the future. The Company and its operations are
also subject to state and local regulation through such measures as zoning,
water quality standards emissions, and building codes.

  The Company also is subject to Canadian labeling laws for products sold in
British Columbia, Ontario and Quebec. The Greenver produce to be marketed by the
Company is subject to Mexican public health and environmental laws and
regulations.

  The Company may become subject to additional laws or regulations administered
by the FDA, the USDA or other federal, state, foreign or local regulatory
authorities, the repeal of laws or regulations or more stringent interpretations
of current laws or regulations.  The Company cannot predict the nature of any
new laws, regulations or interpretations, or what effect they might have on its
business.  Changes in these laws could require the reconfiguration of the
Company's production, processing and transportation methods or increased
compliance costs, and could require the Company to make significant capital
expenditures or incur higher operating costs.  Any failure by the Company to
comply with applicable laws and regulations could subject the Company to civil
penalties, including fines, injunctions, greenhouse or pack house closings,
recalls or seizures, as well as potential criminal sanctions, any of which could
have a material adverse effect on the Company.

  The Company has never received notice of alleged violation of any of these
laws or regulations.  To date, the Company's regulatory compliance costs have
not been significant although there can be no assurance that the Company will
not experience significant compliance costs in the future.

Company Trademarks

  The Company or the LLC has used the trademark consisting of the words
"Colorado Greenhouse Quality Hydroponic Produce," together with the circular
sunrise over snowcapped mountains design (the "Design Mark") and the trademark
"Colorado Greenhouse" (collectively, the "Marks") to identify its produce since
at least September 1993, each of which has been registered in the United States.
The Marks are placed directly on produce as well as on packaging and promotional
materials. The Company has also filed a Canadian trademark application covering
the "Colorado Greenhouse" trademark in Canada.

  In connection with the Company's new marketing campaign scheduled to begin in
September 1998, the Company has designed new trademarks for its products.  The
Company has filed an intent to use trademark application for these new marks in
the United States.

Stock Option Plan

  The Company's Board of Directors and stockholders adopted the 1996 Stock
Option Plan, effective November 19, 1996.  The Stock Option Plan permits the
grant of non-qualified options ("NQOs") and incentive stock options ("ISOs") to
employees, directors and consultants of the Company or any affiliated companies.
The plan expires on November 1, 

                                       47
<PAGE>
 
2006. A total of 1,580,135 shares of Common Stock have been reserved for awards
under the plan, and as of May 31, 1998, options to purchase 1,117,495 shares
have been granted, 1,026,691 shares of which remain outstanding. Options
covering 52,794 shares of Common Stock have been exercised at a price per share
of $0.74. The Stock Option Plan is administered by the Compensation Committee of
the Board of Directors (the "Committee"). The Committee has the discretion to
determine the employees and consultants to whom options may be granted under the
Stock Option Plan and the manner in which such options will vest. The maximum
number of shares subject to one or more awards that can be granted during the
term of the Stock Option Plan to any employee, consultant or director is 450,000
shares of Common Stock, and ISOs may be granted only to employees. ISOs must
have an exercise price equal to the fair market value of the Common Stock on the
date of grant (110% in the case of an ISO granted to an employee who owns Common
Stock having more than 10% of the total voting power of the Company). Options
granted under the Stock Option Plan are not transferable other than by will or
by the laws of descent and distribution.

  Upon (i) the reorganization (other than a bankruptcy reorganization), merger
or consolidation of the Company (except where the Company is the continuing
company and there is no change in the terms of the outstanding shares of Common
Stock), (ii) the sale of all or substantially all of the assets of the Company
(except where the Company continues as a holding company of an entity that
conducts the business formerly conducted by the Company), or (iii) the
dissolution or liquidation of the Company, all outstanding options will
terminate automatically when the event occurs if the Company gives the option
holders 30 days' prior written notice of the event.  Notice is not required for
a merger or consolidation or for a sale if the Company, the successor or the
purchaser makes adequate provision for assumption of all outstanding options or
the substitution of new options on terms comparable to the outstanding options.
The Committee may, in its sole discretion, accelerate the vesting of any option,
in whole or in part, under the foregoing circumstances.

Limitation of Liability and Indemnification Matters

  The Company's Amended and Restated Certificate of Incorporation (the
"Charter") and Amended and Restated Bylaws (the "Bylaws") provide for the
indemnification of the Company's directors and officers to the fullest extent
permitted by Delaware law. The Company's Charter also eliminates to the fullest
extent permitted by Delaware law, liability of a director to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director. As
a result of this provision, the Company and its stockholders may be unable to
obtain monetary damages from a director for breach of his or her duty of care.

persons also is a beneficial owner of shares of the Company's Series A Preferred

Sale of Series B Convertible Preferred Stock
    
  In January 1997, the Company completed the $15 million sale of its Series B
Convertible Preferred Stock at $8.00 per share to Catterton-Simon Partners III,
L.P. (875,000 shares), BCI Growth IV, L.P. (875,000 shares), Catterton-CGH
Partners, L.L.C. (31,250 shares) and H&Q Colorado Greenhouse Investors, LLC
(93,750 shares), an affiliate of one of the Representatives of the Underwriters
(together, the "Purchasers").  Craig H. Sakin, a director of the Company, is a
manager of the entity that is the general partner of Catterton-Simon Partners
III, L.P. and is the manager of the entity that is the managing member of
Catterton-CGH Partners, LLC.  In connection with the sale of the Series B
Convertible Preferred Stock, the Company and the Purchasers entered into a
Registration Rights Agreement, whereby the Company agreed to register the Common
Stock issued upon conversion of the Series B Convertible Preferred Stock in
certain circumstances, at the Company's expense.  See "Description Of Capital
Stock--Registration Rights."  Initially, the Series B Convertible Preferred
Stock was convertible into Common Stock on a one share for one share basis.  In
September 1997, the conversion rate of the Series B Convertible Preferred Stock
was reduced to 1.88235 shares of Common Stock for each Series B share, or an
effective conversion price of $4.25 per share.  This reduction was part of a
negotiated agreement with the Series B stockholders as a result of the Company's
production problems in 1997.  Based on the terms of the Series B Preferred
Stock, the conversion rate will increase to approximately 1.69 shares of Common
Stock for each Series B share, based on an assumed initial public offering price
of $10.00 per share.  If the initial public offering price is higher than
$10.00, the Series B Preferred Stock will convert automatically into a fewer
number of shares of Common Stock.  For example, if the initial public offering
price is $11.00 per share, the Series B Preferred Stock will convert
automatically into 3,030,680 shares of Common Stock.      

Sale of Series C Convertible Preferred Stock
    
  In May 1998, the Company completed the sale of $6.0 million of its Series C
Convertible Preferred Stock at $5.50 per share.  The Series C Convertible
Preferred Stock was offered by the Company in two tranches solely to its
existing preferred stockholders or their related parties on a pro rata basis.
Messrs. Mercure (29,471 shares), Hurth (20,754 shares) and Wetherbee (5,658
shares), all directors of the Company, were among the existing stockholders who
purchased shares of the Series C Convertible Preferred Stock.  The Company also
sold 5,891 shares of Series C Convertible Preferred Stock to Mr. Rinella
although he was not a stockholder at the time.  The Company entered into a
Registration Rights Agreement with the Series C Convertible Preferred Stock
purchasers, whereby the Company agreed to register the Common Stock issued upon
conversion of the Series C Convertible Preferred Stock in certain circumstances,
at the Company's expense.  See "Description of Capital Stock--Registration
Rights."  The Series C Convertible Preferred Stock converts into Common Stock on
a one share for one share basis, subject to adjustment for stock splits, stock
dividends, recapitalizations, dilutive issuances and similar matters.

Registration Rights
    
  Holders of 7,840,041 shares of Common Stock (the "Registrable Securities") and
their permitted transferees have registration rights as a result of agreements
entered into by the Company in connection with the issuance of the Series A
Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible
Preferred Stock.      

  The Series A Registration Rights Agreement grants certain holders of Series A
Preferred Stock (and the Common Stock issued upon conversion) demand and piggy
back registration rights. Subject to the rights of the holders of the

                                       52
<PAGE>
 
Series B Convertible Preferred Stock to override any demand registration request
by the holders of the Series A Preferred Stock and certain minimums, the Series
A Registration Rights Agreement provides that holders representing at least 30%
of the issued and outstanding registrable securities as defined in the Series A
Registration Rights Agreement may initiate a demand registration on Form S-1,
and holders representing at least 20% of the outstanding shares of Series A
registrable securities may initiate a demand registration on Form S-3. In
addition, holders of the Series A Preferred Stock have the right to piggyback
their shares onto any registered offering of Common Stock, subject to customary
underwriter cutbacks and a cutback in the event the holders of Series B
Convertible Preferred Stock also elect to include shares in such offering.

  The Series B Registration Rights Agreement grants certain holders of Series B
Convertible Preferred Stock (and the Common Stock issued upon conversion) demand
and piggyback registration rights, the ability to override any demand
registration request by the holders of the Series A Preferred Stock and a
priority over the Series A Preferred Stock in a piggyback registration in the

piggyback registration rights.  The Series C Convertible Preferred Stock
piggyback registration rights are subject to customary underwriter cutback and
the priority rights of the holders of the Series B Convertible Preferred Stock.

Anti-Takeover Provisions

  General.  Various provisions of the Delaware General Corporation Law ("DGCL")
and the Company's Charter and Bylaws could have the effect of delaying,
deterring or preventing a future takeover or change in control of the Company
unless the takeover or change in control is approved by the Company's Board of
Directors, even though such a transaction may offer the Company's stockholders
the opportunity to sell their stock at a price above the prevailing market
price.  These provisions also may render the removal of directors and management
more difficult.

  Charter and Bylaws.  Upon consummation of the offering, the Company's Charter
provides that all stockholder action must be effected at a duly called meeting
and not by written consent in lieu of a meeting.  The Charter and Bylaws also
provide that special meetings of the stockholders may be called only by the
Secretary at the direction of the Board of Directors and that directors may only
be removed for cause.  Any amendment of these provisions will require the
affirmative vote of at least 66 2/3% of the Company's outstanding voting stock.

  DGCL.  Section 203 of the DGCL ("Section 203") prevents an "interested
stockholder" (defined generally as a person owning 15% or more of a
corporations's outstanding voting stock) from engaging in a "business
combination" with a publicly-held Delaware corporation for a period of three
years following the date such person became an interested stockholder, unless:
(i) before such person became an interested stockholder, the board of directors
of the corporation approved either the business combination or the transaction
that resulted in the stockholder becoming an interested stockholder; (ii) upon
consummation of the transaction that resulted in the stockholder becoming an
interested stockholder, the interested stockholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced (excluding for purposes of determining the number of shares
outstanding those shares held by directors who are also officers or by employee
stock plans in which employee participants do not have the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer); or (iii) following the transaction in which such
person became an interested stockholder, the business combination is approved by
the board of directors and authorized at a meeting of stockholders, and not by
written consent, by the affirmative vote of at least 66 2/3% of the outstanding
voting stock that is not owned by the interested stockholder.

  Section 203 defines a business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, transfer, pledge or other disposition of 10% or more of the assets of the
corporation involving the interested stockholder; (iii) subject to various
exceptions, any transaction that results in the issuance or transfer by the
corporation of any of its stock to the interested stockholder; (iv) any
transaction involving the 

                                       53
<PAGE>
 
corporation that has the effect of increasing the proportionate shares of stock
of any class or series of the corporation beneficially owned by the interested
stockholder; or (v) the receipt by the interested stockholder of the benefit of
any loans, advances, guarantees, pledges or other financial benefits provided by
or through the corporation.

Transfer Agent and Registrar

  The Company has selected American Securities Transfer & Trust as the transfer
agent and registrar of the Common Stock.


                        SHARES ELIGIBLE FOR FUTURE SALE

  Prior to this offering, there has been no public market for the Common Stock,
and no prediction can be made of the effect, if any, that the sale or
availability for sale of shares of Common Stock will have on the market price of
the Common Stock.  Sales of substantial amounts of such shares in the public
market, or the perception that such sales could occur, could adversely affect
the market price of the Common Stock and could impair the Company's future
ability to raise capital through an offering of its equity securities.
    
  Upon consummation of this offering, the Company will have outstanding
13,998,361 shares of Common Stock.  Of these shares, the 5,000,000 shares sold
in this offering will be freely tradable without restriction under the
Securities Act, unless purchased by "affiliates" of the Company as that term is
defined in SEC Rule 144.   All of the remaining 8,998,361 shares of Common Stock
are "restricted securities" within the meaning of Rule 144 and may be sold in
the public market only if registered or if sold under an exemption from
registration under the Securities Act, including the exemption provided by Rule
144.  Approximately 7,918,032 shares of these restricted securities have been
held for more than one year and will be immediately saleable under Rule 144,
subject to the Underwriters' lock-up and the volume limitations imposed by Rule
144.      

  In general, under Rule 144 as currently in effect, an affiliate of the
Company, or person (or persons whose shares are aggregated) who has beneficially
owned restricted securities for at least one year (including the holding period
of any prior owner except an Affiliate) is entitled to sell in any three-month
period a number of shares that does not exceed the greater of (i) 1% of the
number of shares of Common Stock then outstanding (approximately 139,998 shares
immediately after this offering); or (ii) the average weekly trading volume of
the Common Stock on the Nasdaq National Market/sm/ during the four calendar
weeks immediately preceding.  Sales under Rule 144 are also subject to
requirements relating to manner of sale, notice and availability of current
public information about the Company.  Under Rule 144(k), a person (or persons
whose shares are aggregated) who has not been an affiliate of the Company at any
time during the 90 days immediately preceding the sale and who has beneficially
owned his or her shares for at least two years is entitled to sell such shares
without complying with the manner of sale, public information, volume limitation
or notice provisions of Rule 144.  In general, under Rule 701, any employee,
consultant or advisor of the Company who purchases shares from the Company
pursuant to Rule 701 in connection with a compensatory stock or option plan or
other written agreement is eligible to resell, unless contractually restricted,
such shares 90 days after the effective date of this offering in reliance on
Rule 144, but without compliance with certain restrictions, including the
holding period, contained in Rule 144.

  All of the Company's officers, directors, option holders and various
stockholders, who own in the aggregate ________ shares of Common Stock, have
agreed with the Underwriters that they will not offer for sale, sell or
otherwise dispose of any shares of Common Stock owned by them and will not
exercise any registration rights to which they are entitled for 180 days from
the date of this Prospectus without the prior written consent of BT Alex. Brown
Incorporated.

          The Company intends to file a registration statement on Form S-8 under
the Securities Act covering shares of Common Stock reserved for issuance under
the 1996 Stock Option Plan.  See "Management--Stock Option Plan."  The Company
expects to file this registration statement as soon as practicable after the
effective date of this offering. Accordingly, shares registered under such
registration statement will, subject to Rule 144 volume limitations applicable
to affiliates of the Company, be available for sale in the open market, unless
such shares are subject to vesting requirements under the 1996 Stock Option Plan
or the lock-up agreements described above.  As of May 31, 1998, options to
purchase 1,026,691 shares of Common Stock remain outstanding under the 1996
Stock Option Plan.

Alex. Brown Incorporated and Hambrecht & Quist LLC (the "Representatives"), have
severally agreed to purchase from the Company and the Selling Shareholders the
following respective number of shares of Common Stock at the initial public
offering price less the underwriting discounts and commissions set forth on the
cover page of this Prospectus:

                                                               ================

  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to various conditions precedent and that the Underwriters will
purchase all of the shares of Common Stock offered hereby if any such shares are
purchased.

  The Company and the Selling Stockholder have been advised by the
Representatives that the Underwriters propose to offer the shares of Common
Stock to the public at the initial public offering price set forth on the cover
page of this Prospectus and to certain dealers at such price less a concession
not in excess of $___ per share.  The Underwriters may allow, and such dealers
may re-allow, a concession not in excess of $____ per share to certain other
dealers.  After commencement of the initial public offering, the offering price
and other selling terms may be changed by the Representatives.

  Certain Selling Stockholders have granted to the Underwriters an option,
exercisable not later than 30 days after the date of this Prospectus, to
purchase up to 750,000 additional shares of Common Stock at the initial public
offering price less the underwriting discounts and commissions set forth on the
cover page of this Prospectus.  To the extent that the Underwriters exercise the
option, each of the Underwriters will have a firm commitment to purchase
approximately the same percentage thereof that the number of shares of Common
Stock to be purchased by each of them in the above table bears to 5,000,000, and
these Selling Stockholders will be obligated, pursuant to the option, to sell
such shares to the Underwriters.  The Underwriters may exercise the option only
to cover over-allotments made in connection with the sale of Common Stock
offered hereby.  If purchased, the Underwriters will offer such additional
shares on the same terms and those on which the 5,000,000 shares are being
offered.

  The Underwriting Agreement contains covenants of indemnity and contribution
among the Underwriters, the Selling Stockholders and the Company regarding
certain civil liabilities, including liabilities under the Securities Act.

  To facilitate the offering of the Common Stock, the Underwriters may engage in
activities that stabilize, maintain or otherwise affect the market price for the
Common Stock.  Specifically, the Underwriters may over-allot shares of the
Common Stock in connection with this offering, thereby creating a short position
in the Underwriters' syndicate account. Additionally, to cover such over-
allotments or to stabilize the market price of the Common Stock, the
Underwriters may bid for, and purchase, shares of the Common Stock in the open
market.  Any of these activities may maintain the market price of the Common
Sock at a level above that which might otherwise prevail in the open market.
The Underwriters are not required to engage in these activities, and, if
commenced, any such activities may be discontinued at any time. The
Representatives, on behalf of the Underwriters, also may reclaim selling
concessions allowed to an Underwriter or dealer, if the syndicate repurchases
such shares distributed by that Underwriter or dealer.

                                       55

  The Company has agreed that it will not issue any shares of Common Stock or
options, rights or warrants to acquire Common Stock for a period of 180 days
after the date of this Prospectus, without the prior written consent of BT Alex.
Brown Incorporated, except for shares issued (i) in connection with acquisitions
and (ii) pursuant to the exercise of options granted under the Stock Option
Plan.  All of the Company's officers, directors, option holders and various
stockholders, who own in the aggregate ________ shares of Common Stock, have
agreed with the Underwriters that they will not offer for sale, sell or
otherwise dispose of any shares of Common Stock owned by them and will not
exercise their demand registration rights for 180 days from the date of this
Prospectus without the prior written consent of BT Alex. Brown Incorporated.

  The Representatives have advised the Company that the Underwriters do not
intend to confirm sales to any accounts over which they exercise discretionary
authority.
    
  Hambrecht & Quist LLC, one of the Representatives of the Underwriters, served
as the placement agent for the Company in the sale of its Series B Convertible
Preferred Stock.  In connection with this role, Hambrecht & Quist LLC was paid a
placement fee of $897,500 and was issued the Warrant on January 21, 1997 for the
purchase of up to 18,500 shares of the Series B Convertible Preferred Stock for
$8.00 per share.  The Warrant contains an automatic exercise provision triggered
upon completion of this offering and a net issue election, pursuant to which
Hambrecht & Quist LLC will be issued 16,466 shares of Common Stock, assuming an
initial public offering price of $10.00 per share.  An affiliate of Hambrecht &
Quist LLC, H&Q Colorado Greenhouse Investors, LLC, purchased 93,750 shares of
Series B Convertible Preferred Stock in January 1997 and 20,416 shares of Series
C Convertible Preferred Stock in the May 1998 Private Placement, which will
automatically convert into 158,438 and 20,416 shares of Common Stock,
respectively, upon consummation of this offering (assuming an initial public
offering price of $10.00 per share).      

  Prior to this offering, there has been no public market for the Common Stock.
Consequently, the initial public offering price for the Common Stock will be
determined by negotiations between the Company and the Representatives. Among
the factors to be considered in such negotiations are prevailing market
conditions, the results of operations of the Company in recent periods, the
capital structure of the Company, the market capitalizations and stages of
development of other companies which the Company and the Representatives believe
to be comparable to the Company, estimates of the business potential of the
Company, the present state of the Company's development and other factors deemed
relevant by the Company and the Representatives.


                                 LEGAL MATTERS

  The validity of the Common Stock offered hereby will be passed upon for the
Company by Holme Roberts & Owen LLP, Boulder, Colorado.  Certain legal matters
related to this offering will be passed upon for the Underwriters by Piper &
Marbury L.L.P., Baltimore, Maryland.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Colorado Greenhouse Holdings, Inc.:

We have audited the accompanying consolidated balance sheets of COLORADO
GREENHOUSE HOLDINGS, INC. (a Delaware corporation) and subsidiaries as of
December 31, 1996 and 1997, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1997. 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 audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our 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 Colorado Greenhouse
Holdings, Inc. and subsidiaries as of December 31, 1996 and 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               DECEMBER 31, 1997



(1)    ORGANIZATION AND BUSINESS
       -------------------------
    
Colorado Greenhouse Holdings, Inc. (the "Company") is a Delaware holding company
incorporated in 1996. Effective January 1, 1997, Colorado Greenhouse, LLC
("LLC"), a Colorado limited liability company, underwent a reorganization and,
together with the formation of Colorado Greenhouse, Inc. ("INC"), became
wholly-owned subsidiaries of the Company, for the purpose of operating and
managing greenhouse facilities utilizing environment enhancing greenhouses to
produce premium tomatoes for sale to national supermarket chain stores. To
facilitate the reorganization, the members of LLC exchanged their ownership
interests for 6,200,000 shares of the Company's Series A Preferred Stock. The
financial statements reflect the reorganization as if it had occurred at the
inception of LLC.       

As of December 31, 1997, the Company owns one and leases four greenhouses in
Colorado, consisting of approximately 91 acres, including one 20-acre
greenhouse, which was constructed in 1997 and began production in 1998. In
addition, the Company owns and operates a 20-acre greenhouse in New Mexico,
which was constructed and began production in 1997.
    
On January 21, 1997, the Company sold 1,875,000 shares of Series B Preferred
Stock for a total of $15,000,000 in a private equity transaction to outside
investors, to fund in part, the construction of two greenhouses owned by INC.
The Company also incurred syndication costs of $1,493,000, which have been
netted against the proceeds of the Series B Preferred Stock.       

(2)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
       ------------------------------------------

       Basis of Presentation
       ---------------------

The accompanying consolidated financial statements include the accounts of the
Company and all subsidiaries. All significant intercompany accounts and
transactions have been eliminated in consolidation.

       Cash and Cash Equivalents
       -------------------------

For purposes of these consolidated financial statements, the Company considers
all highly-liquid investments with original maturities of three months or less
to be cash equivalents. The carrying amount approximates fair value because of
the short maturities of those instruments. 


                                      F-7

market. All direct and allocated indirect costs incurred in connection with the
production of the crop are capitalized to inventory. Direct and allocated
indirect costs include among other things, propagation costs, utilities, labor,
property taxes and equipment maintenance. Inventories consist of the following

       Property and Equipment
       ----------------------
    
Property and equipment are recorded at cost, including construction period
interest and other costs incurred on self-constructed assets. Property and
equipment and accumulated depreciation are relieved upon retirement or sale and
the gain or loss is recorded as income or expense. Major betterments and
renewals are capitalized while replacements, maintenance and repairs which do
not improve or extend the lives of the respective assets are charged to expense
as incurred. All property and equipment are depreciated on the straight-line
method over their estimated useful lives ranging from 3 to 25 years (see Note
3). Depreciation expense was $182,000, $290,000 and $705,000 for the years ended
December 31, 1995, 1996 and 1997, respectively, and is included in cost of goods
sold in the accompanying consolidated statements of operations. Capitalized
interest for the year ended December 31, 1997, was $305,000 with no such amounts
capitalized in 1995 and 1996.

       -----------------
    
The Company has adopted Statement of Position 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use" ("SOP 98-1"), which
provides guidance on when costs related to software developed or obtained for
internal use should be capitalized or expensed. SOP 98-1 divides the development
of internal-use computer software into three stages: (1) the preliminary project
stage, during which conceptual formulation and evaluation of alternatives takes
place, (2) the application development stage, during which design, coding,
installation and testing takes place, and (3) the operations stage, during which
training and maintenance takes place. Costs incurred during the preliminary
project stage and the operations stage are expensed by the Company as incurred.
Costs incurred during the application development stage are capitalized. Process
reengineering activities are also expensed as incurred.        
    
During the year ended December 31, 1997, the Company capitalized approximately
$1.1 million related to the design, coding, installation and testing of computer
software developed for internal

use. These amounts are included in computer equipment (Note 3) and are amortized
using the straight-line method over 5 years. The Company evaluates impairment of
the computer software in accordance with Statement of Financial Accounting
Standards No. 121, as explained below. No impairment expense has been recognized
during the year ended December 31, 1997.       

       Other Assets
       ------------
    
Other assets represent organizational costs and deferred financing costs, net of
amortization (Note 5). Organizational costs are being amortized over five years
on a straight-line basis. Deferred financing costs, which consist of commitment
and legal fees incurred in connection with financing arrangements to fund
greenhouse construction are being amortized over eight years. Amortization
expense for the years ended December 31, 1995, 1996 and 1997, was $48,000,
$48,000 and $100,000, respectively. For the year ended December 31, 1997,
$53,000 of amortization is included in interest expense.       

       Pervasiveness 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 and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

       Advertising
       -----------

The Company expenses advertising costs as they are incurred. Advertising costs
were approximately $438,000, $416,000 and $290,000 for the years ended December
31, 1995, 1996 and 1997, respectively, and is included in sales and marketing
expense in the accompanying consolidated statements of operations.

       Asset Impairment
       ----------------

In accordance with Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of," the Company reviews its assets for impairment whenever events
of changes in circumstances indicate that the carrying value of an asset may not
be recoverable. For assets which are held and used in operations, the asset
would be impaired if the undiscounted future cash flows related to the asset did
not exceed the net book value.

       Significant Customers and Concentration of Credit Risk
       ------------------------------------------------------

The Company had three customers in 1995 which accounted for approximately 13%,
11% and 10% of the Company's revenues and two customers in 1996 which accounted
for approximately 19% and 16% of the Company's revenues. The Company had three
customers in 1997 which accounted for approximately 24%, 15% and 14% of the
Company's revenues. 


                                      F-9

The trade receivables potentially subject the Company to a high concentration of
credit risk. The Company currently markets its tomatoes in ten states, primarily
to major supermarket chains. The majority of the Company's sales are
concentrated in California, Colorado, Michigan, Ohio, Tennessee and Texas. The
Company establishes an allowance for doubtful accounts based on factors
surrounding the credit risk of specific customers, historical trends and other
information. 

       Income Taxes
       ------------
 
Deferred taxes are provided on the liability method whereby deferred tax assets
are recognized for deductible temporary differences and operating loss
carryforwards and deferred tax liabilities are recognized for taxable temporary
differences. Temporary differences are the differences between the reported
amounts of assets and liabilities and their tax bases. Deferred tax assets are
reduced by a valuation allowance when, in the opinion of management, it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. Deferred tax assets and liabilities are adjusted for the effects of
changes in tax laws and rates on the date of enactment.

       Earnings per Share
       ------------------  

The Company has adopted Statement of Financial Accounting Standards No. 128,
"Earnings Per Share," by retroactively restating per share amounts for all
periods presented. "Basic earnings (loss) per share" is determined by dividing
net income (loss), or net income available to common stockholders, when
applicable, by the weighted average number of common shares outstanding during
each period. "Diluted earnings (loss) per share" includes the effects of
potentially issuable common stock, but only if dilutive (i.e., a loss per share
is never reduced). The treasury stock method, using the average price of the
Company's common stock for the period, is applied to determine dilution from
options and warrants. The if-converted method is used for convertible
securities. A potentially dilutive warrant convertible into 18,500 shares of
mandatorily redeemable Series B Preferred Stock was excluded from the
calculation of diluted earnings per share because its effect is antidilutive.

A reconciliation of the numerator and denominators used in computing per share
amounts is as follows:

       New Accounting Pronouncements
       -----------------------------
    
The Financial Accounting Standards Board ("FASB") has issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
130"). SFAS 130 requires that all items recognized as comprehensive income be
reported in the financial statements. Comprehensive income items include
unrealized holding gains/losses on securities classified as available for sale,
foreign currency translation adjustments and minimum pension liability
adjustments which will be shown as an increase or decrease to net income or loss
to arrive at comprehensive income. The Company adopted SFAS 130 in the first
quarter of 1998, however, the Company did not have any transactions which would
require additional disclosure under SFAS 130.        

The FASB has also issued Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information" ("SFAS
131"). SFAS 131 requires that a public business enterprise report financial and
descriptive information about its reportable operating segments. Generally,
financial information is required to be reported on the basis that it is used
internally for evaluation of segment performance and deciding how to allocate
resources to segments. The Company adopted SFAS 131 in the first quarter of
1998, however, the Company does not separate operating results internally by
segment.
    
In addition, the FASB issued Statement of Financial Accounting Standards No.
132, "Employers' Disclosure About Pension and Other Postretirement Benefits"
("SFAS 132"). SFAS 132 revises disclosure requirements for pension and other
postretirement benefits. The Company does not currently have any postretirement
benefit plans and, therefore, this new standard will not have an impact on the
Company's financial statements.       
    
The FASB also issued Statement of Financial Accounting Standards No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133").
SFAS 133 requires that companies recognize all derivatives as either assets or
liabilities in the balance sheet at fair value. Under SFAS 133, accounting for
changes in fair value of a derivative depends on its intended use and
designation. The Company is currently assessing the effect of this new standard.

The American Institute of Certified Public Accountants has issued Statement of
Position 98-5, "Reporting on the Costs of Start-Up Activities" ("SOP 98-5"). SOP
98-5 requires that all non-governmental entities expense the costs of start-up
activities, including organization costs, as those costs are incurred, and is
effective for fiscal years beginning after December 15, 1998. The Company has
reviewed the provisions of SOP 98-5 and does not believe adoption of this
standard will have a material effect upon its results of operations, financial
position or cash flows.       

       Unaudited Pro Forma Earnings Per Share
       --------------------------------------

The Company's historical capital structure is not indicative of its prospective
structure due to the automatic conversion of all shares of convertible preferred
stock and outstanding warrant into common stock concurrent with the closing of
the Company's anticipated initial public offering ("IPO").

Pro forma earnings (loss) per share is computed using the weighted average
number of common shares outstanding during the period assuming the conversion of
convertible preferred stock issued into common stock as of the date of issuance.
In a prospectus covering the sale of common shares, whenever the proceeds of the
sale are to be used to retire long-term debt, disclosure of pro forma earnings
per share is required. Accordingly, the Company has assumed the sale of an
adequate number of shares of common stock such that the proceeds therefrom
retire all long-term debt and excluded interest expense on the retired debt from
net income (loss). 

       Unaudited Pro Forma Information
       -------------------------------
    
Upon closing of the Company's IPO, all of the outstanding shares of Series A, B
and C Preferred Stock, including the warrant convertible into Series B Preferred
Stock, will be automatically converted into shares of common stock (see Notes 7,
13 and 14 for conversion terms). The unaudited pro forma consolidated balance
sheet as of June 30, 1998, reflects the conversion of approximately 9,176,000
shares of Preferred Stock into approximately 10,476,000 shares of common stock.
     
    
Pro forma basic (loss) earnings per share for the year ended December 31, 1997,
and for the six months ended June 30, 1998, giving effect to the conversion of
all outstanding shares of Preferred Stock into shares of common stock, are
$(0.12) and $0.26, respectively. Pro forma diluted (loss) earnings per share for
the year ended December 31, 1997, and for the six months ended June 30, 1998,
are $(0.12) and $0.25, respectively.        

The unaudited pro forma information on the accompanying consolidated statements
of operations for the years ended December 31, 1995 and 1996, is presented for
the purpose of showing the impact on net income had the Company been a taxable
entity in those years at an effective tax rate of 38%.

       Unaudited Interim Financial Statements
       --------------------------------------
    
The financial statements as of June 30, 1998, and for the six months ended June
30, 1997 and 1998, are unaudited and include all adjustments (consisting only of
normal recurring adjustments) which are, in the opinion of management, necessary
for a fair presentation of the results for such interim periods.       


                                     F-12
<PAGE>
 
    
Due to the seasonal nature of the operations of the Company, the results of
operations for the six months ended June 30, 1998, are not necessarily
indicative of the results to be expected for the entire year.       

       Reclassifications
       -----------------

Certain reclassifications have been made to the prior period financial
statements to conform to the current period presentation.

(4)    DEPOSITS AND PREPAID RENT
       -------------------------
    
Under operation and management agreements ("O&M") at its greenhouses (Note 10),
LLC is required to pay primary fees, essentially rent, on a quarterly basis.
Terms of the O&M agreements grant LLC the right to defer quarterly payments if a
cash deficiency is projected in the following quarter and correspondingly
require LLC to maintain refundable deposits with the lessors in escrow accounts
to fund such deferrals totaling approximately $2,314,000. As a result of a flood
(Note 9) in July 1997, LLC elected to defer third quarter 1997 rent payments and
the lessors exercised their rights to withdraw the appropriate funds from the
escrow accounts creating an obligation on the Company to replenish these
accounts. At December 31, 1996 and 1997, and June 30, 1998, the deposits were
approximately $2,314,000, $1,583,000 and $2,314,000, respectively.

In addition, under one of the O&M agreements, the Company has prepaid rent in
the amount of $427,000, which is being amortized over the life of the lease on a
straight-line basis. The unamortized amount of the prepaid rent as of December
31, 1996 and 1997, was $341,000 and $299,000, respectively.

Effective January 24, 1997, INC executed a master loan agreement with Colorado
Springs Credit Association, a federally chartered association of the Farm Credit
System, to secure construction loans totaling $15,000,000, and a working capital
line with a cap of $1,500,000. Proceeds derived from the line of credit have
been made available to LLC by a loan supplement executed of even date. Advances
under the line of credit bear interest at the prime rate less .25% (8.25% at
December 31, 1997) and are secured by eligible accounts receivable and
inventories, as defined. As of December 31, 1997, proceeds drawn against the
line of credit were $500,000.

The commitment for the construction loans had an expiration date of September
30, 1997. As a result of construction delays, the Company had requested and Farm
Credit Services has approved extensions to move the expiration date to May 31,
1998. Effective May 1, 1998, the loans will be converted to a term note with 108
equal principal payments plus interest. Under the terms of the master loan, the
Company may elect to be charged interest (at a variable rate) at the average
prime lending rate published in the Wall Street Journal or at a fixed rate equal
to the U.S. Treasury Rate plus 2.5%. Under the Treasury Rate Option, individual
amounts may be fixed for periods ranging from one year to maturity with the
minimum amount that may be fixed at any one time for a single period of
$1,000,000. 

As part of the master loan agreement, the construction loan and line of credit
are cross-collateralized by substantially all of the assets of the Company and
its subsidiaries. Additionally, the Company must meet certain financial
covenants, including a minimum debt service ratio, current ratio and net worth
as well as other negative covenants. As of December 31, 1997, the Company was
not in compliance with the minimum debt service ratio and the capital
expenditure limitations. Noncompliance with the minimum debt service ratio was
waived until March 31, 1998, at which point the Company was in compliance.
Noncompliance with the capital expenditure limitations has been waived until
December 31, 1998, at which point the Company expects to be in compliance.

The carrying value of the Company's long-term debt approximates fair value due
to the variable nature of the interest rates.

(7)    CAPITAL STOCK
       -------------

       Series B Preferred Stock
       ------------------------
 
The Company has 1,875,000 shares outstanding of its Series B Preferred Stock
with a liquidation preference of $8 per share. The Series B Preferred Stock is
convertible into shares of common stock, at the option of the holders, at a
conversion ratio of 1.33 to 1.88 shares of common per each share of Series B
Preferred Stock, based upon future operating results. However, the Series B
Preferred Stock will convert automatically upon the closing of an IPO, assuming
the aggregate proceeds and per-share amounts exceed certain thresholds. The
holders of the Series B Preferred Stock have the option to require the Company
to redeem, at $8 per share, up to 50% of the outstanding shares, or $7,500,000,

(8)    INCOME TAXES
       ------------

The Company files a consolidated return for both Federal and State income taxes.
Prior to 1997, the Company was a Limited Liability Company and, as such, the
taxable income or loss passed through to the individual members. Effective
January 1, 1997, the Company became a C corporation due to the reorganization
discussed in Note 1. As a result, the cumulative effect of the Company's
temporary differences were recorded on January 1, 1997, and the corresponding
income tax benefit was not material. The income tax benefit for the year ended
December 31, 1997, consists of the following (in thousands):

(9)    FLOOD LOSS
       ----------

In July 1997, the Company experienced a flash flood that destroyed the crop at
the Company's 20-acre greenhouse at Ft. Lupton. The estimated economic loss was
2,000,000 and included the expense to replace the crop and the loss of income
related thereto. Subsequently, an insurance claim was filed and, in January
1998, insurance proceeds, net of deductibles, were recovered in the amount of
$802,000, which is reflected in other receivables in the consolidated balance
sheet as of December 31, 1997.

(10)   COMMITMENTS
       -----------

The Company has four greenhouses which are located adjacent to electrical
cogeneration facilities, (three owned by related parties) for which it has
entered into separate O&M agreements. The related party O&M agreements were

remaining O&M agreement was effective January 1, 1996, with an expiration date
in 2002. During the term of these agreements, LLC is required to pay to each
facility a primary fee for rent. Primary fees for the years ended December 31,
1995, 1996 and 1997 were approximately $2,740,000, $3,287,000 and $3,429,000,
respectively, and are included in cost of goods sold in the accompanying

       Statement of Financial Accounting Standards No. 123 ("SFAS 123")
       ----------------------------------------------------------------
    
SFAS 123, "Accounting for Stock-Based Compensation," defines a fair value based
method of accounting for employee stock options or similar equity instruments.
However, SFAS 123 allows the continued measurement of compensation cost for such
plans using the intrinsic value based method prescribed by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"),
provided that pro forma disclosures are made of net income or loss, assuming the
fair value based method of SFAS 123 has been applied. The Company has elected to
account for its stock-based compensation under APB 25, recognizing $715,000 and
$540,000, in 1996 and 1997, respectively. Accordingly, for purposes of the pro
forma disclosures presented below, the Company has computed the fair values of
all options granted during 1996 and 1997, using the Black-Scholes pricing model
and the following weighted average assumptions.

                                              1996                1997
                                       -----------------   -----------------  

         Risk-free interest rate              6.47%               5.70%
         Dividend rate                           0%                  0%
         Expected volatility                    37%                 37%
         Expected life                   2.64 years             3 years


To estimate expected lives of options for this valuation, it was assumed options
will be exercised within one year of becoming fully vested. All options are
initially assumed to vest. Cumulative compensation cost recognized in pro forma
net income or loss with respect to options that are forfeited prior to vesting
is adjusted as a reduction of pro forma compensation expense in the period of
forfeiture. Because the Company's common stock is not yet publicly traded, the
expected market volatility was estimated using the estimated average volatility
of two publicly held companies which the Company believes to be similar with
respect to the markets in which they compete. Actual volatility of the Company's
stock may vary. Fair value computations are highly sensitive to the volatility
factor assumed; the greater the volatility, the higher the computed fair value
of the options granted.
    
Using these assumptions, the fair value of the stock options granted in 1996 and
1997 was approximately $1,449,000 and $658,000, respectively, or approximately
$2.60 and $1.34, respectively, per common share, which would be amortized as
compensation expense over the vesting period of the options. Had compensation
costs been determined consistent with SFAS 123, utilizing the assumptions
detailed above, the Company's net income (loss) would have been the following on
a pro forma basis (in thousands):

       Warrant
       -------

In January 1997, in connection with the issuance of the Series B Preferred
Stock, the Company issued a warrant that entitles the holder to purchase 18,500
shares of Series B Preferred Stock of the Company at $8 per share. The warrant
automatically exercises prior to the sale of the Company or an IPO or
immediately prior to expiration, January 31, 2002. The estimated fair market
value of the warrant was recorded and determined using the Black-Scholes pricing
model.

(14)   EVENTS SUBSEQUENT TO DATE OF INDEPENDENT
       ---------------------------------------- 
           PUBLIC ACCOUNTANTS REPORT (UNAUDITED)
           -------------------------------------

During May 1998, the Company issued approximately 1,091,000 shares of
mandatorily redeemable Series C Preferred Stock predominantly to existing Series
A and B Preferred Stock shareholders for $6,000,000. The Series C Preferred
Stock has a liquidation preference of $5.50 per share and is convertible into
shares of common stock, at the option of the holders, on a one-for-one basis.
The Series C Preferred Stock will convert automatically upon closing of an IPO,
assuming the aggregate proceeds and per-share amounts exceed certain thresholds.
The holders of the Series C Preferred Stock have the option to require the
Company to redeem, at $5.50 per share, up to 50% of the outstanding shares, or
$3,000,000, in January 2004 and the remaining 50%, or $3,000,000, in January
2005.

During May 1998, the Company acquired a 25% equity interest in a group of
Mexican greenhouse companies ("Greenver") for $4,000,000 cash. Greenver
currently has 88 acres of non-hydroponic greenhouses in Baja, Mexico, primarily
growing tomatoes. The Company also received exclusive rights to market all of
the produce form Greenver and earn a 10% sales commission upon sale. The Company
must remit to Greenver monthly the amount of sales of Greenver tomatoes, less
commissions to the Company, and anticipates that this will require additional
working capital because the Company's customers typically do not pay sales
invoices in less than thirty days. The Company will account for its investment
in Greenver using the equity method of accounting.
    
During May 1998, the Company experienced hail damage to its two greenhouses in
Brush, Colorado. The resultant effect was to remove the entire crop at one
greenhouse and a decrease in production volumes at the second greenhouse with
replacement of glass and plastic where needed. For the period ended June 30,
1998, the Company recorded a loss from the hail damage of approximately
$1,700,000. A majority of this loss resulted from property replacement costs of
approximately $750,000 and inventory losses of approximately $625,000. During
June 1998, the Company was notified that its insurance carrier would advance $2
million in partial settlement of the estimated losses and the Company was paid
in early July 1998. For the period ended June 30, 1998, the Company has
recognized insurance proceeds of $1,608,000. The remaining $392,000 will be
recognized over the remaining estimated period of "interruption." The Company
also anticipates that it will receive additional settlement amounts relative to
business interruption from the insurance company, but cannot estimated those
amounts at this time.

Item 17.   Undertakings
    
          Insofar as indemnification for liabilities arising under the 
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant, the Registrant has been informed that in the opinion
of the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment of the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by a controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by a final adjudication of such
issue.      

          The undersigned registrant hereby undertakes to provide to the
underwriter at the closing specified in the underwriting agreements certificates
in such denominations and registered in such names as required by the
underwriter to permit prompt delivery to each purchaser.

          The undersigned registrant hereby undertakes that:

          (i) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this registration statement in reliance upon Rule 430A and contained in the form
of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be a part of this
registration statement as of the time it was declared effective.

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

Re:  Colorado Greenhouse Holdings, Inc.
     Registration Statement on Form S-1 (File No. 333-57329)

Gentlemen:

As counsel for Colorado Greenhouse Holdings, Inc., a Delaware corporation (the
"Company"), we have examined the above-referenced Registration Statement on Form
S-1 under the Securities Act of 1933, as amended (the "Registration Statement"),
that the Company is filing with respect to the registration of 5,750,000 shares
(the "Shares") of its Common Stock, including 2,250,000 shares of its Common
Stock to be issued concurrently with the offering upon conversion of outstanding
shares of the Company's preferred stock (the "Preferred Stock").

We have also examined the Company's Certificate of Incorporation, as amended,
By-laws and the record of its corporate proceedings and have made such other
investigation as we have deemed necessary in order to express the opinion set
forth below.

Based on such investigation, it is our opinion that the Shares have been, or
upon conversion of the Preferred Stock pursuant to the terms thereof will be,
duly and legally issued and fully paid and non-assessable.

We hereby consent to all references to us in the Registration Statement and all
amendments to the Registration Statement.  We further consent to the use of this
opinion as an exhibit to the Registration Statement.  We express no opinion as
to any matters not expressly set forth herein.

                          GREENHOUSE LEASE AGREEMENT


         THIS GREENHOUSE LEASE AGREEMENT, dated as of this 8th day of June,
1989, is between COLORADO POWER PARTNERS, a Colorado general partnership
("Landlord") and BRUSH GREENHOUSE PARTNERS, a Colorado general partnership
("Tenant").

                                   RECITALS
                                   --------

         A.   Landlord is the owner of the real property described on Exhibit A
attached, hereto (the "Project Property"). Landlord is constructing a net 50
megawatt cogeneration facility on the Project Property, consisting of an
electrical generating facility (the "Power Plant"), an approximately 18-acre
greenhouse facility, an adjacent packing facility and certain related
facilities.

         B.   Tenant has entered into a Greenhouse Management Agreement, dated
March 16, 1989 , as amended pursuant to an Amendment to Greenhouse Management
Agreement, dated June 8, 1989, with Spring Gardens, Inc. pursuant to which
Tenant will retain Spring Gardens, Inc. as a consultant to assist in the
construction and operation of the greenhouse facility and CPP Engineers and
Constructors will retain Spring Gardens, Inc. as a consultant to assist in
connection with the construction of the greenhouse facility and packing
facility.

         C. Landlord and Tenant desire to enter into this Lease in order for
Tenant to lease the greenhouse and packing facility from Landlord and to provide
for the purchase by Tenant of the thermal output of Landlord's electrical
generating facilities for use in heating the greenhouse.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties hereby covenant and agree as follows:

         1.   Premises. (a) Landlord hereby leases to Tenant and Tenant leases
              --------                                                      
from Landlord a portion of the Project Property, consisting of that certain real
property depicted on the Plot Plan attached hereto as Exhibit A, and all
structures, buildings and all appurtenances, hereditaments, and easements
thereon, including the greenhouse and packing facility to be constructed

purpose of access to and repair, maintenance and replacement of the emergency
boilers, the fertilizer/irrigation system and any other equipment under the
control of Tenant relating to the operation of the Premises and located in the
Auxiliary Building.

              (c)  The Premises shall consist of an approximately 18-acre
greenhouse facility and an approximately 12,000 square feet packing facility
(which facility will include packing, storage and office facilities). It is the
parties' intention that the Premises consist of the greenhouse and the packing
facility to be constructed on the Project Property approximately in the location
depicted on Exhibit A attached hereto and that this Lease and the definition of
"Premises" herein shall cover all such facilities, even if not constructed in
the exact location depicted on Exhibit A attached hereto. It is also the
parties' intention that the easement to use the Auxiliary Building granted
pursuant to paragraph 1(b) above cover such building even if not constructed in
the exact location depicted on Exhibit B attached hereto. At such time as the
greenhouse facility, packing facility and Auxiliary Building have been
constructed Landlord and Tenant shall enter into an amendment to this Lease
incorporating the description of the greenhouse and packing facility set forth
on such survey as the description of the Premises and the description of the
auxiliary building set forth on such survey as the description of the Auxiliary
Building.

          (d) Landlord warrants that so long as Tenant is not in default
hereunder, Tenant shall have peaceful and quiet use and possession of the
Premises, subject to any mortgage and all matters of record or other agreements
to which this Lease is or hereafter may be subordinated.

        2.  Term. The term (the "Term") of this Lease shall commence on the date
            ----
specified by Landlord in a written notice from Landlord to Tenant (the date
which Landlord specifies the Term of the Lease is to commence is referred to
herein as the "Commencement Date"). The Commencement Date specified by Landlord
in such notice must be on or before July 1, 1992. Landlord may terminate this
Lease in the event of default as defined hereinafter. The Term of the Lease

earlier of (i) at the election of Landlord with the consent of Lender (as
hereinafter defined) , the expiration or termination of the Category Number 4A
On-System Power Purchase

                                      -2-
<PAGE>
 
Agreement, dated August 29, 1988, between Landlord and Public Service Company of
Colorado (the "Power Purchase Agreement") (relating to Landlord's Power Plant
adjacent to the Premises); (ii) the fifteenth anniversary of the Commencement
Date, (iii) the data mutually agreed to in writing by the Landlord and Tenant,
with the consent of Lender, or (iv) at the option of The Prudential Insurance
Company of America, Pruco Life Insurance Company, their successors or assigns or
the holder(s) of any mortgage, deed of trust, assignment of rent or similar
instrument encumbering the Premises (collectively, "Lender") , upon the
acceleration by any Lender of the entire amount of any debt of Landlord to such
Lender secured in whole or in part by the Premises.

        3.   Termination. This Lease shall terminate as provided in paragraph
             -----------
2(ii) above without the necessity of any notice from either Landlord or Tenant
to terminate the same. This Lease shall terminate as provided in paragraph 2(i)
or (iv) above ten days after receipt by Tenant of written notice from the
Landlord (with respect to paragraph 2(i)) or Lender (with respect to paragraph
2(iv)). To the extent permitted by law, Tenant hereby waives notice to vacate or
quit the Premises except as expressly provided above and agrees that Landlord
shall be entitled to the benefit of all provisions of the law respecting summary
recovery of possession of the Premises from Tenant holding over to the same
extent as if statutory notice had been given.

        4.  Holding Over. If Tenant shall be in possession of the Premises at
            ------------
the end of the Term, with consent or permission of Landlord and Lender, the
tenancy under this Lease shall become month-to-month upon all of the terms and
conditions contained in this Lease and such tenancy shall be terminable by
either party upon thirty (30) days' notice to the other party. If Tenant shall
be in possession of the Premises at the end of the Term without the consent or
permission of the Landlord and Lender, Tenant shall pay rent in an amount equal
to twice the rental due pursuant to paragraph 6 below for the time that Tenant
holds over. Payment of such amount by Tenant or receipt of such amount by
Landlord shall not be construed as consent by Landlord to Tenant's holding over.

        5.  Use. Tenant agrees to promptly plant the first crop as soon as is
            ---
reasonably practicable at a time mutually agreed upon by the parties. Use of the
Premises shall be, exclusively for the growing, processing, packaging and
marketing of tomatoes and other greenhouse products and related uses incident
thereto. Tenant agrees to use no less than 90% of the usable growing space in
the Premises for the

                                      -3-
<PAGE>
 
growing of tomatoes. Tenant may use the remaining 10% of the usable growing
space in the Premises for growing such other crops as Tenant desires. Tenant may
not use more than 10% of the usable growing space in the Premises for growing
any crop other than tomatoes without the prior written consent of Landlord and
Lender. Landlord and Lender shall not unreasonably withhold their consent to
such growing of other crops provided that Tenant establishes to Landlord's and
Lender's reasonable satisfaction that such crops are as economically viable as
tomatoes under the projections presented as part of the Application (as defined
in paragraph (a) (i) (below) and that the growing of such crops will not violate
Landlords/ FERC Order (as defined in paragraph 22 below) . Notwithstanding the
foregoing, in the event that Landlord determines that Tenant's growing of any
crops other than tomatoes in any way jeopardizes Landlord's FERC Order, Tenant
shall immediately cease growing such crops.

     6.   Rental.
          -------

          a. Rental Amount.  Tenant shall pay during the Term of this Lease as
             --------------                                                   
rent for the Premises, without any prior demand, setoff, counterclaim, deduction
or abatement whatsoever, the sum Eight Hundred Sixty Five Thousand Two Hundred
Dollars ($865,200) per year, payable in equal monthly installments of Seventy
Two Thousand One Hundred Dollars ($72,100) each, which installments shall
commence on the Commencement Date, and shall be due and payable in advance on
the first day of each end every month thereafter during the entire Term of this
Lease, unless Tenant elects to defer up to the first four monthly installments
of rent as provided in paragraph 6(b) below.

           b.   Deferral of Rent. Tenant may, at Tenant's option, defer payment
                ----------------
of up to but not more than the first four monthly installments of rent due under
this Lease as set forth below. In lieu of payment of any such monthly
installment of rent, Tenant shall provide Landlord with a notice of its
intention to defer payment of such monthly installment of rent. The total amount
of monthly rent deferred in accordance with this subparagraph (b) is referred
,to herein as the "Deferred Rental Amount." The number of months that payment of
rental is deferred in accordance with this subparagraph (b) is referred to
herein as the "Deferral Period." The Deferred Rental Amount plus interest
thereon (at the rate equal to the greater of (i) two percent (2%) per annum
above the rate interest publicly announced or published from time to time by
Morgan Guaranty Trust Company of New York as its "prime rate" or (ii) ten
percent (10%) per annum) shall be payable in equal monthly installments

                                      -4-
<PAGE>
 
commencing on the first day  of  the month following the Deferral Period. If the
Deferral Period is one or two months, plus interest shall be payable in the
Deferred Rental Amount nine equal monthly installments. If the Deferral Period
is three or four months, the Deferred Rental Amount plus interest shall be
vavable in 18 equal monthly installments. Tenant may, at Tenant's option, prepay
all or any part of the Deferred Rental Amount at any time, on the condition the
amount of any such pre-payment, must be at least $25,000.

        c.   Payment of Rental. Tenant shall pay all rental when due and
             -----------------
payable, without any setoff, counterclaim, abatement, deduction or prior demand
therefor whatsoever except for gas deductions as expressly provided in paragraph
7(b)(i) below. In addition, any rental (other than the Deferred Rental Amount.
to the extent that it is not yet due and payable) which is not paid within ten
days after the same is due shall bear interest, at the default rate of eighteen
percent (18%) per annum from the first day due until paid. Unless otherwise
directed in writing by Landlord and consented to by Lender, payment of rent
shall be made to Central Bank Denver, National Association for deposit in the
Revenue Account (as such term is defined in the Deposit and Disbursement
Agreement between Landlord, Lender and Central Bank Denver, National
Association). The payment of rent and all other sums due hereunder is
independent of each and every other covenant and agreement contained in this
Lease.

         d.  Limitation on Distributions. Tenant agrees that prior to
             ---------------------------                             
making any distributions of profits or other sums to the partners of Tenant
pursuant to Tenant's  partnership agreement, Tenant shall have deposited and
there shall then be on deposit in an escrow account for the benefit of Landlord
an amount equal to one year's rental under this Lease. Such account shall be
maintained in the name of Colorado Power Partners/Brush Greenhouse Partners at
Central Bank Denver, National Association or such other financial institution as
may be designated by Landlord and reasonably acceptable to Lender; and Tenant,
Landlord and Central Bank or such other financial institution designated by
Landlord and reasonably acceptable to the Lender, shall enter into an escrow
agreement acceptable to Landlord and Lender providing that in the event Tenant
fails to make any payment of rent hereunder, Landlord shall be entitled to
withdraw from such escrow account by transferring from such account to the
Revenue Account all amounts necessary to pay any rent and any other sums that
Tenant fails to pay hereunder. Tenant shall have no obligation to establish such
account unless and until Tenant desires to make a distribution of profit or
other sums to the partners of Tenant.

                                      -5-
<PAGE>
 
             e.  Payment for Additional Heat.  It is the parties' intention that
                 ---------------------------
Landlord provide only the amount of thermal energy set forth in paragraph
7(a)(i) below. If (i) the Landlord is operating the Power Plant in excess of the
Base Operating Level (as defined below and determined on a monthly basis) solely
for the purpose of supplying additional thermal energy to the greenhouse in
excess of the Thermal Requirement (as defined below and determined on a monthly
basis) or (ii) Lender reasonably determines that Landlord is operating the Power
Plant in excess of the Base Operating level (determined on a monthly basis)
solely for the purpose of supplying additional thermal energy to the greenhouse
in excess of the Thermal Requirement (determined on a monthly basis), then
Tenant shall pay Landlord as additional rent an amount equal to Landlord's
cumulative marginal cost of operating the Power Plant above the Base Operating
Level, less the cumulative marginal revenue generated from operating the Power
Plant above the Base Operating Level, as reasonably determined by Landlord and
reasonably approved by Lender, directly attributable to providing such
additional thermal energy in excess of the Thermal Requirement for such month.
Base Operating Level means the Power Plant, thermal energy and electrical energy
output rate (determined on a monthly basis) set forth on Table 2a. to the
Application (as defined below) , a copy of which Table is attached hereto as
Exhibit C, as such level may be adjusted upward from time to time by the
Landlord, due to increased requirements of Public Service Company of Colorado
under the Power Purchase Agreement, such adjustment to be with the consent of
Lender.

        7.   Net Lease.
             ---------

             a.  It is the intention of the parties to this Lease that all rents
reserved herein during the Term shall be a net return to Landlord and all
expenses or charges with respect to the Premises including, by way of example,
irrigation water, maintenance, landscaping, repairs remodeling or alteration of
the building, structures or improvements, utilities, and the like shall be borne
by Tenant and not Landlord, except as follows:

                 (i)  As part of the rental being paid by Tenant to Landlord
        hereunder, Tenant is purchasing thermal heat from the power plant in
        such quantities as may be available to operate Tenant's greenhouse
        operations in accordance with the parameters set forth in that certain
        Application for a Certification of Qualifying Status as a Cogeneration
        Facility (the "Application") submitted by Landlord to the

                                      -6-
<PAGE>
 
Federal Energy Regulatory Commission ("FERC"), Docket No. QF89-7-000. Table 2a
attached to the Application (a copy of which Table is attached hereto as Exhibit
C) sets forth the amount of greenhouse heat required on a monthly basis. The
amount of greenhouse heat required set forth in Table 2a is referred to herein
as the "Thermal Requirement." For purposes of this Section 7 (a) (i) , the
Thermal Requirement shall be determined on a weekly basis by dividing the
monthly amount set forth on Table 2a by 4.33. If the Landlord fails on a weekly
basis to provide thermal energy in an amount equal to 80% of the Thermal
Requirement for such week, and Tenant is reasonably required to operate the
emergency boilers in order to heat the greenhouse, Landlord shall reimburse
Tenant for the actual cost to Tenant of natural gas required to operate the
emergency boiler to provide thermal energy in an amount equal to the difference
between 80% of the Thermal Requirement for such week and the actual output of
thermal energy from the power plant during such week. In no event shall, such
reimbursement from Landlord to Tenant in any month, exceed $25,000 even if the
actual gas cost incurred by Tenant exceeds that amount. At all times when
Landlord is providing thermal heat from the power plant in an amount equal to
80% of the Thermal Requirement, Landlord will not be liable for any gas cost
incurred by Tenant even if 80% of the Thermal Requirement does not provide
adequate thermal heat for the greenhouse;

         (ii) Landlord shall provide, at no cost to Tenant, domestic water for
employees of Tenant situated on the Premises in amounts no greater than those
customarily used in similar greenhouse operations.  As set forth in paragraph 13
below, Landlord shall not be required to and shall not provide any water to
Tenant for irrigating the greenhouse crops;

        (iii)  Pursuant to paragraph 13 below, Tenant is responsible for
arranging for and paying the cost of all electrical and similar utility service
to the Premises.  However, Landlord shall use reasonable efforts to provide
Tenant emergency backup electrical power service utilizing electricity produced
from the power plant except that Landlord shall have no

                                      -7-
<PAGE>
 
obligation to provide any such service if it would jeopardize its ability to
meet its obligation to supply power pursuant to the Power Purchase Agreement or
any replacement or successor agreement or to meet its own internal demand.
Landlord is agreeing to attempt to provide such emergency backup electrical
power to Tenant as an accommodation to Tenant and if Landlord is unable for any
reason to provide such emergency backup service to Tenant, Tenant agrees to hold
Landlord harmless from any and all claims, demands, costs, liabilities or
damages of any nature whatsoever arising out of Landlord's failure to provide
such emergency backup electrical service for any reason. In the event that
Landlord provides emergency backup electrical service to Tenant, Tenant shall,
immediately upon demand, pay Landlord an amount equal to the amount that Tenant
would have paid it's primary provider of electrical service for such amount of
electrical power;

        (iv)  Landlord shall be responsible for maintenance (but not the
cost) of "All Risk" casualty insurance with respect to the Premises, which
insurance may be carried at the discretion of Landlord in such amounts and with
such companies as Landlord shall determine, on the condition that Tenant shall
within 15 days after written notice from Landlord reimburse Landlord for the
cost of such insurance attributable to the Premises. Tenant shall be solely
responsible for insurance an the contents and operations of the greenhouse; and

        (v)   Landlord shall, on arrangements satisfactory to Landlord, permit
Tenant to use the irrigation well located on the Project Property for irrigation
of the greenhouse crops. Tenant agrees to release and hold Landlord harmless
from and against any and all claims, demands, liabilities or damages of any
nature whatsoever arising out of (A) Tenant's use of such well, (B) Landlord's
failure to make such well available for Tenant's use if Landlord is prohibited
from doing so by any federal, state or local governmental determination or law,
ordinance, rule or regulation or (C) the failure of such well to supply adequate
quantities of water to irrigate greenhouse crops.

         8. Taxes. Tenant shall pay in each tax year during the Term all real
            -----
estate taxes, ad valorem taxes and assessments, general and special, including
taxes levied against the buildings or structures comprising part of the Premises
assessed by the taxing authorities. In the event that the Premises is taxed as a
part of the Project Property, Landlord shall make a fair and equitable
apportionment of the total taxes among the remainder of the Project Property and
the Premises. Landlord shall advise Tenant, in writing, of the amount of the
taxes reasonably apportioned to the Premises and Tenant shall tender such amount
to Landlord within 15 days of receipt of written request from Landlord. In
addition, Tenant shall be responsible for all taxes payable to the appropriate
taxing authorities for any sales, excise or other tax (not including real
property tax) levied, imposed or assessed in the State of Colorado or any other
political subdivision thereof or other taxing authority for Tenant's crops,
inventory, furniture, trade fixtures, improvements installed by Tenant or by
Landlord on behalf of Tenant and any other property of Tenant. Tenant shall,
upon request of Landlord, provide proof of payment of such taxes to Landlord
annually by providing a receipt marked "paid" for the taxes assessed, and any
failure to pay such taxes when due shall be considered a default under this
Lease.

         9.   Maintenance, Repairs and Alterations.

reasonable wear and tear excepted, and to operate the Premises and the Related
Facilities in accordance with this Agreement and accepted industry standards
throughout the Term, of this Lease. Landlord shall maintain the Auxiliary
Building.

example, the roofs on all improvements comprising a part of the Premises. Tenant
shall not make any repairs to the Premises and the Related Facilities in excess
of $25,000 (other than emergency repairs to protect the Premises and the Related
Facilities) unless and until Tenant shall have caused the plans and
specifications therefor to have been reviewed by Landlord and shall have
obtained Landlord's written approval thereof and shall have obtained the
reasonable consent of Lender. If approval is granted, Tenant shall cause the
work described in such plans and specifications to be performed, at its expense,
promotly, efficiently, competently and in a good and work like manner by duly
qualified or licensed persons or entities. All such work shall comply with all
applicable codes, rules, regulations and ordinances.

        (c) Tenant will surrender the Premises and the Related Facilities at
the expiration of the Term or at such other time as it may vacate the Premises
in as good condition as when received, excepting depreciation caused by ordinary
wear and tear.

        (d) Tenant will repair promptly, at its expense, any damage to the
Premises and the Related Facilities regardless of fault or by whom such damage
shall be caused, unless caused by Landlord or any agents, employees or
contractors in the exclusive employment of Landlord (and not the joint
employment of Landlord and Tenant).

   10.  Alterations bv Tenant. Tenant shall not make any alterations,
        ---------------------
renovations, improvements or other installations in or about any part of the
Premises in excess of $25,000 unless and until Tenant shall cause plans and
specifications therefor to have been reviewed by Landlord and shall have
obtained Landlord's written approval thereof and the reasonable consent, of
Lender. If approval is granted, Tenant shall cause the work described in such

Facilities or the Project Property.

         11.  Mechanics' Liens.   The Landlord's title is and always shall be
              ----------------
paramount to the title of the Tenant and nothing in this Lease shall empower the
Tenant to do any act which can, shall or may encumber the title of the Landlord.
No work performed by Tenant pursuant to this Lease, whether in the nature of
erection, construction, alteration or repair shall be deemed to be made for the
immediate use and benefit of Landlord so that no mechanics, or other liens shall
be allowed against the Premises or the estate of Landlord by reason of any
consent given by Landlord to Tenant, to improve, alter or repair the Premises.
Tenant shall pay promptly all persons furnishing labor and/or materials with
respect to any work performed by Tenant or its contractors on or about the
Premises. If any mechanics' or other liens shall at any time be filed against
the Premises by reason of work, labor, services or materials performed or
furnished, or alleged to have been performed or furnished, to Tenant or to
anyone holding the Premises through or under Tenant, Tenant shall forthwith
cause the same to be discharged of record or bonded to the satisfaction of
Landlord and Lender.

         12. Operations. (a) Subject to the limitations set forth in paragraph
             ----------
5 above, the Premises shall be used by Tenant exclusively for the growing and
marketing of greenhouse fruits and vegetables, using the thermal heat available
from, the power plant. It is agreed and understood that it is Landlord's
paramount concern that continuous production of greenhouse fruits and vegetables
be undertaken so as to continuously qualify the Landlord's cogeneration facility
for the cogeneration benefits pursuant to Landlord's FERC order, as the same may
be amended from time to time. Tenant shall continuously operate the greenhouse
facilities for the production of fruits and vegetables, and any failure to have
crops in place, and under production for a period in excess of forty-five (45)
days shall be considered an event of default under this Lease. Tenant warrants
that it will promptly pay, all of its bills, including labor costs, and any
judgments, liens, or the like which may threaten Tenant's performance of its
obligations under this Lease or the continued operation  and maintenance of the
Premises or the status of the cogeneration facility as a qualifying facility
under

                                      -11-
<PAGE>
 
Landlord's FERC Order. Any failure by Tenant to promptly pay such bills,
judgments, liens or like charges shall be considered a default by Tenant under
this Lease. Landlord may pay any such claims upon ten (10) days' notice to
Tenant, and any claims paid by Landlord on behalf of Tenant will become
immediately due and owing to Landlord and Landlord may collect such sums paid
together with interest at the default interest, rate of eighteen percent (18%)
per annum.

          (b) Tenant shall, at all times, keep the Premises in a neat and
orderly condition. Specifically by way of example and not by way of limitation,
Tenant shall keep any garbage, trash, rubbish, refuse, disassembled equipment or
vehicles out of public view within containers or structures and shall provide
for the timely removal of any such garbage, trash, rubbish, refuse, disassembled
equipment or vehicles from the site at Tenant's expense.

      13. Utilities. Except as set forth in paragraph 7 above with respect to
          ---------

Premises, Tenant shall be responsible for providing and paying for all utilities
of  any nature whatsoever used in connection with the Premises, including but
not limited to the following:

          (a) Tenant shall pay for all costs associated with irrigation water
required in connection with the operation of the Premises including all costs

the well 1ocated on the Project Property and the treatment of the water produced
by such well.

          (b) Tenant shall pay the cost of wastewater discharge to the City of
Brush from the Premises. Landlord does not currently intend to separately meter
Tenant's discharge of wastewater from the Premises. Accordingly, Landlord shall
reasonably apportion the total charges imposed by the City of Brush for the
discharge of wastewater from the Premises and the Project Property between
Landlord and Tenant based upon the amount of wastewater discharged to the City
of Brush by each party.

          (c) Tenant shall be responsible for arranging for and paying for all
electrical service to the Premises.

shall and does hereby agree to

                                      -12-

Engineer") and the officers, directors, employees, representatives, invitees and
agents of each (collectively, the "Indemnified Parties") and save the 
Indemnified Parties harmless and, at the Indemnified Parties' option, defend the
Indemnified Parties from and against any and all claims, actions, damages, 
liabilities and expenses including attorneys' fees or professional fees and

Tenant of the Premises or the Related Facilities occasioned wholly or in part by
any act or omission of Tenant, its officers, agents, directors, employees or 
invitees.

        b. Tenant Insurance. At all times after the Commencement Date, Tenant 
           ----------------
will carry and maintain, at its expense:

contractual liability under this Lease, in such amounts as Landlord may 
reasonably request;

          (ii) all-risk casualty insurance covering all of Tenant's personal 
property on the Premises including all leasehold improvements installed in the

of the Construction and Term Loan Agreement between Landlord and Lender.

        
        c. Insurance Provisions: The company or companies writing such 
           --------------------
insurance, as well as the form of such insurance shall at all times be subject
to Landlord's and Lender's approval. Public liability and all-risk casualty

endorsements as Landlord may request.

                                     -13-
<PAGE>
 
        15. Performance by Landlord. If Tenant shall fail to perform any of its 
            -----------------------
obligations under this Lease, Landlord may perform the same and the cost of same
shall be charged to Tenant and Tenant agrees, upon five (5) days' written 
notice, to pay Landlord promptly the cost thereof with default interest at the 
rate of eighteen percent (18%) per annum until paid.

        16. Condemnation. (a) If the whole or any part of the Premises shall be

part so taken on the date Tenant is required to yield possession thereof to the 
condemning authority. Landlord may, but shall have no obligation to make such 
repairs and alterations as may be necessary in order to restore the part not 
taken to useful condition. If Landlord elects to make such repairs, this Lease 
shall remain in full force and effect and Landlord shall make an equitable 
adjustment in the rent to reflect the reduction, if any, in Tenant's ability to 
utilize the Premises for greenhouse operations resulting from such taking. If 
the aforementioned taking renders the remainder of the Premises unsuitable for 
the permitted use and Landlord does not elect to make repairs necessary to 
restore the part not taken to useful condition, either party may terminate this 
Lease as of the date when Tenant is required to yield possession by giving 
notice to that effect within thirty (30) days after such date nd this Lease 
shall terminate upon receipt of such notice. In the event that Tenant remains in
possession of the Premises after such taking, Tenant shall continue to pay rent 
through the date of termination of this Lease.

            (b) All compensation awarded for any taking of the Premises or any 
interest therein shall belong to and be the property of Landlord, Tenant hereby 
assigns to Landlord all rights with respect thereto; provided, however, nothing 
contained herein shall prevent Tenant from applying for reimbursement from the 
condemning authority (if permitted by law) for moving expenses, or the expense 
of removal of Tenant's trade fixtures, or loss of Tenant's business goodwill, 
but only if such action shall not reduce the amount of the award or other 
compensation otherwise recoverable from the condemning authority by Landlord.

        17. Assignments and Subletting; Landlord's Consent Required. Tenant 
            -------------------------------------------------------

default provisions of this Lease, Tenant nevertheless shall remain liable for
any rental and any other additional sums or damages which may be due or for
which

                                      -17-
<PAGE>
 
Tenant is liable, or in respect of which Tenant has agreed to indemnify Landlord
under any of the provisions of this Lease or sustained by Landlord prior to
such termination, and all reasonable costs, fees and expenses including, but not
limited to, reasonable attorneys' fees, costs and expenses incurred by Landlord
in pursuit of its remedies hereunder, or in renting the Premises to others from
time to time (all such rental, other sums, damages, costs, fees and expenses
being referred to herein collectively as "Termination Damages"). In addition to
Termination Damages and all other damage remedies available to Landlord under
any applicable law, Tenant agrees that, at the election of Landlord, Landlord
shall be entitled to either of the following damage remedies:

        a.  An amount equal to the rental which, but for termination of this
Lease, would have become due during the remainder of the Term, less the amount
of rental, if any, which Landlord shall receive during such period from others
to whom the Premises may be rented, which such damages shall be computed and
payable in monthly installments, in advance, on the first day of each calendar
month following termination of the Lease and continuing until the date on which
the Term would have expired but for such termination; any suit or action brought
to collect any such damages for any month shall not in manner prejudice the
right of Landlord to collect any similar damages for any subsequent month by a
similar proceeding; or

        b.  An amount equal to the present value (as of the date of such
termination and discounted at the rate of 10% per annum) of rental which, but
for termination of this Lease, would have become due during the remainder of the
Term, less the fair rental value of the Premises for the remainder of the Term 
(discounted at the same rate) as determined by an independent real estate
appraiser named by Landlord (the cost of which appraiser shall be borne equally

          1.   EFFECTIVE DATE; DURATION
               OF OBLIGATIONS
               ------------------------

               1.1  Effective Date. The "Effective Date" of this Agreement
                    --------------
is the date first set forth above, notwithstanding any prior or subsequent date
of execution or ratification. All obligations of both parties, shall take effect
on the Effective Date; provided, however, that the demise of the Leased
Premises shall not become effective until the "Commencement Date" as provided
in paragraph 3.2.

               1.2  Duration of Obligations. The leasehold estate to be 
                    -----------------------                             
conferred hereunder shall begin on the Commencement Date and shall remain in
effect until the earlier of (a) the purchase of the entire Leased Premises
(including both the "Land" and the "Facility") by Rocky Mountain, or (b) the
expiration or earlier termination of the Lease Term as to both the Land and

obligations of both parties, shall terminate as of such date; provided, however,
all obligations of both parties which were, by the terms of this Agreement,
required to have been performed prior to such termination date, or are required
by their terms or the context to survive such termination date, shall survive.

2.   LEASE OF PREMISES
     -----------------

        2.1   Demise. Effective on the Commencement Date (but not until such
              ------
date), Thermo shall, and hereby does, lease and demise to Rocky Mountain, for
and during the Lease Term, and subject to all terms and conditions of this
Agreement, that certain Land described in part I of Exhibit A attached hereto
consisting of 35.001 acres, more or less (being a portion of the "Project Site"
also described in Exhibit A), together with certain improvements to real
property and all fixtures and tangible personal property of any nature which,
pursuant to the Construction Contract, shall be constructed on the Land and
furnished for the operation of such improvements as a commercial Greenhouse
prior to the Commencement Date, as provided in section 6; provided, however,
that Thermo shall not be obligated to grant such leasehold interest if Rocky
Mountain or any of Rocky Mountain's Affiliates are then in default under any
then-existing contract between Rocky Mountain or any of Rocky Mountain
Affiliates on one hand, and Thermo or any of Thermo's Affiliates on the other.
Such improvements, fixtures, and personal property, together with any additions
or alterations thereto permitted to be made by Rocky Mountain hereunder, shall
constitute the "Facility". A more complete description of the Facility shall be
included in the Commencement Date Notice to be delivered pursuant to paragraph
3.2. Subject to section 5 (pursuant to which Rocky Mountain may, under certain
circumstances, purchase Facility and, under certain additional conditions, the
Land), the Facility and the Land are hereafter referred to collectively as the
"Leased Premises."


        2.2  Reservations from Description: Restrictive Covenants. At any
             ----------------------------------------------------
time prior to purchase by Rocky Mountain of the entire Leased Premises, Thermo
shall have the right to make reasonable reservations from the interest in
the Land leased hereunder ("Reservations") for such covenants, easements,
licenses, and rights of entry as Thermo may in Thermo's discretion,
reasonably exercised, deem prudent to grant to third parties or retain for
Thermo's business purposes; provided, however, that such Reservations shall not
impair materially the use of the Facility by Rocky Mountain for commercial
agricultural purposes. Thermo shall notify Rocky Mountain a reasonable time
prior to effecting any such Reservations. Within thirty (30) days after
receipt of such Notice(s), Rocky Mountain shall give Notice to Thermo of any
objection by Rocky Mountain stating in such Notice any material impairment of
use for commercial agricultural purposes which will result from such proposed
Reservations. If Rocky Mountain's objection is valid in Thermo's discretion
reasonably exercised, Thermo shall not implement the proposed Reservations. If
no objection is made by Rocky Mountain within such thirty (30) day period, or
if such objection is not valid in Thermo's discretion reasonably exercised,
Exhibit H to this Agreement shall be deemed to have been amended to incorporate
the proposed Reservation. Thermo shall have the right to file with respect to
the Leased Premises, at any time deemed prudent by Thermo, (i) a declaration of
restrictive covenants substantially in accordance with the proposed Declaration
of Covenants set

                                      -7-
<PAGE>
 
forth in Exhibit H and (ii) such instruments as may be necessary or appropriate
to reflect reservations to be granted or retained by Thermo under this paragraph
2.2. Upon filing of such declaration the Leased Premises shall be deemed to have
been made subject to such restrictions prior to the demise thereof to Rocky
Mountain.

3.   LEASE TERM.
     -----------

        3.1   Basis of Commencement Date. The "Commencement Date" of the Lease
              ---------------------------
Term shall be determined, in part, based on progress achieved by Thermo in
construction of the Plant. Thermo shall use reasonable efforts to construct (or
cause to be constructed) the Plant at the Project Site in order to achieve an
initial "Date of Commercial Operation" for the Plant (or a portion thereof) of
January 1, 1994. Prior to achieving a Date of Commercial Operation, Thermo must
substantially complete construction, commence initial operation, and complete
start-up of all or a portion of the Plant. Thermo shall not become liable to
Rocky Mountain in any way if the Commencement Date does not occur because
the Plant is delayed in achieving, or is not expected to achieve, an initial
Date of Commercial Operation. Thermo shall inform Rocky Mountain from time to
time upon inquiry concerning progress toward Financial Closing and thereafter
concerning the Plant construction schedule and process of Plant construction.
Rocky Mountain acknowledges that, among other things, delay in achieving
Financial Closing beyond March 31, 1993 may impact, materially and adversely,
the ability of Thermo to achieve the currently proposed initial Date of
Commercial Operation.

        3.2   Establishment of Commencement Date: Prior Occupancy. The
              ----------------------------------------------------
Commencement Date shall be established in the "Commencement Date Notice" which
shall be to Rocky Mountain by Thermo in the form of Exhibit B attached
hereto. Provided that the Facility is then Substantially Complete as envisioned
in section 6, Thermo shall, not less than sixty (60) days before the date
Thermo anticipates that an initial Date of Commercial operation will be
achieved, give to Rocky Mountain the Commencement Date Notice to the effect
that the Lease Term will commence on such future date (the "Commencement Date")
which, is specified in the Commencement Date Notice; provided, however, that
unless Rocky Mountain shall consent the Commencement Date shall not occur
from October 1 through December 31 (inclusive) of any calendar year. The
Commencement Date Notice shall then be incorporated into this Agreement in
lieu of Exhibit "B". In addition, should it reasonably appear to Thermo that the
Plant will, in all probability, achieve an initial Date of Commercial Operation
at some future date (even if such future date is then uncertain), Thermo shall,
upon request by Rocky Mountain, permit Rocky Mountain to occupy the Facility or
any material portion thereof prior to the Commencement Date for purposes of
initial planting and other preparations for Rocky Mountain's first production of
agricultural products at the Facility. Such prior occupancy shall be on a
provisional basis pursuant to a temporary license incorporating such 
special terms and conditions as the parties shall deem reasonable. In addition,
Thermo may waive the requirement that the Facility be Substantially Complete
prior to giving the Commencement Date Notice should it reasonably appear to
Thermo that Substantial Completion will be achieved prior to the anticipated
initial Date of Commercial Operations.

        3.3   Lease Term Duration. The "Lease Term" shall begin on the
              --------------------                                   
Commencement Date, and shall expire, unless sooner terminated, on the date which
is

                                      -8-
<PAGE>
 
the twenty-fifth (25th) anniversary of the initial Date of Commercial Operation
applicable to the Plant. After the initial Date of Commercial Operation occurs,
Thermo shall confirm the date of expiration of the Lease Term to Rocky Mountain
by Notice. No leasehold estate shall be deemed created until the Commencement
Date shall have occurred. Prior to such date, Rocky Mountain's access to the
facility and the land shall be pursuant to the Construction Contract and any
temporary license which may be granted pursuant to paragraph 3.2.

4.   RENT
     ----

        4.1   Base Rent. Subject to deferral in the manner provided in
              ----------
paragraph 4.6, below and to adjustment in accordance with a certain "Memorandum
Regarding Adjustment of Rent and Option Price" of even date (the form of which
is attached hereto as Appendix I), Rocky Mountain shall pay to Thermo during
that portion of the Lease Term beginning on the Commencement Date and expiring
on the twentieth (20th) anniversary of the initial Date of Commercial Operation
total "Base Rent" for the Leased Premises equal to Seventeen Million, Five
Hundred Twenty-One Thousand, Six Hundred Seventy Eight and 18/100 Dollars ($
17,521,673.18). Subject to deferral and adjustment in like manner, Base Rent for
such initial period shall be paid in seventy-seven (77) equal quarterly
installments of Two Hundred Twenty-Seven Thousand, Five Hundred Fifty-Four and
29/100 Dollars ($227,5554.29). Installments of Base Rent shall be payable in
arrears beginning on the last day (i.e. on March 31, June 30, September 30, or
December 31) of the first complete calendar quarter which commences six (6)
complete calendar months or more after the Commencement Date, and continuing on
the final day of each calendar quarter for seventy-six (76) calendar quarters
thereafter. (For example, if the Commencement Date should be any date from
January 1, 1994 through March 31, 1994, the first installment of Base Rent would
be payable on December 31, 1994; should the Commencement Date be any date from
April 1, 1994 through June 30, 1994, the first installment of Base Rent would be
payable on March 31, 1995, etc.) Such dates on which payments of Base Rent shall
be due (without regard to any Postponement of payment permitted under paragraph
4.6) are hereinafter referred to as "Quarterly Payment Dates." The Quarterly
Payment Dates shall be confirmed in the Commencement Date Notice; subject,
however, to Postponements to the extent permitted under paragraph 4.6. During
the final five (5) years of the Lease Term, Base Rent for the Leased Premises
shall be One Hundred Dollars ($100) per year, payable in advance on the
twentieth (20th) anniversary of the Commencement Day and on the same day of each
year thereafter during the remainder of the Lease Term, and, in addition, Rocky
Mountain shall pay to Thermo any accumulated postponements of Base Rent (plus
interest thereon) which may have been referred and shall then be outstanding
pursuant to paragraph 4.6. During such period, payments of deferred Base Rent
shall be made at such time and in such amounts as is provided in such paragraph
4.6.

        4.2   Additional Rent. Rocky Mountain also shall pay, as "Additional 
              ----------------                     
Rent", all real property and other property taxes, all governmental assessments
levied during the Lease Term against the Leased Premises (including without
limitation the Land) for improvements benefiting the Leased Premises during the
Lease Term, and all other costs or charges of any nature whatsoever which Rocky
Mountain is expressly required by this Agreement to pay with respect to the
Leased Premises during The Lease Term, including, without limitation any
apportionment of insurance premiums allocated to

                                      -9-
<PAGE>
 
Rocky Mountain under paragraph 9.6. This obligation shall survive expiration of
the Lease Term. Additional Rent shall be paid by Rocky Mountain making payment
of such costs and charges directly to the third party entitled to receive
payment therefor; provided, however, that unless Thermo notifies Rocky
Mountain to make real property tax payments directly to the taxing authority,
all real property taxes and assessments shall be paid to Thermo as Additional
Rent at least ten (10) days before the same would become delinquent. Should the
present method of property taxation or assessment be changed so that there
would be substituted for the whole or any part of the real property taxes or
assessments now or hereafter imposed on the Leased Premises or any part thereof,
a capital tax or other tax imposed on the rent or any other payments received by
Thermo from Rocky Mountain, such other tax, to the extent that it is so
substituted, shall be included in determining Thermo's real property tax bill
for the relevant years, and shall be paid by Rocky Mountain as Additional Rent.

        4.3   Manner and Application of Payment. Except as is expressly
              ---------------------------------
permitted pursuant to paragraph 4.6, all rent and other charges of any nature
required to be paid by Rocky Mountain to Thermo under this Agreement, including
without limitation Base Rent, Additional Rent, and Thermal Payments shall be
paid to Thermo on or before the due date in immediately available funds without
Notice or demand. Payments shall be made at the office of Thermo from time to
time provided for delivery of Notices or to such other address and/or payee, as
Thermo may from time to time designate by Notice to Rocky Mountain. Payments
shall be applied first to pay Additional Rent and other costs and expenses which
shall become payable to Thermo hereunder, second to Thermal Payments required
hereunder, third to Base Rent then currently due and payable hereunder (unless
Rocky Mountain shall then be entitled to and shall elect to defer payment of
Base Rent under paragraph 4-6) and fourth to "Postponements" and accrued
interest thereon as provided in paragraph 4.6 in order of the longest
outstanding to the shortest outstanding Postponement. Payment of those
components of Additional Rent which Rocky Mountain is obligated to Pay directly
to third parties hereunder shall be made in a timely manner, as the applicable
creditors may from time to time direct. Nothing, herein shall create any privity
of contract between Thermo and any third-party creditors of Rocky Mountain, or
otherwise make Thermo responsible for any debts of Rocky Mountain. All covenants
in this Agreement with respect to payments of any nature to be made by Rocky
Mountain, except payment of Thermal Payments, are and shall be deemed to be
independent covenants.

        4.4   Least Not Terminable Prior to Payment of Base Rent. Except
              ---------------------------------------------------
as otherwise expressly set forth in this Agreement, the demise of the Leased
Premises provided in this Agreement shall not expire or become terminable by
Rocky Mountain for any reason whatsoever prior to payment to Thermo in full of
the entire Base Rent provided in paragraph 4.1. Until Base Rent for the Lease
Term shall be paid in full, or until Rocky Mountain shall have purchased the
entire Leased Premises as provided in section 5, below, Rocky Mountain waives
all rights which may now or hereafter be conferred by law to abandon, terminate,
or surrender the leasehold estate, in whole or in part, or to any abatement,
suspension, diminution, deduction, or reduction whatsoever of Base Rent. Nothing
in this paragraph 4.4 or in any other paragraph of this Agreement shall be
construed as a waiver of any claims which may become assertable by Rocky
Mountain against Thermo under this Agreement, or as a relinquishment by Rocky
Mountain of the right of setoff against Base Rent with respect to such claims.

          4.5   Determination of "Available Net Cash"; Restrictions on
                ------------------------------------------------------
Distributions.  Beginning on the first complete calendar quarter which 
- -------------                                                               
commences six (6) complete calendar months or more after the Commencement Date,
and continuing throughout the first twenty (20) years of the Lease Term, Rocky
Mountain shall calculate "Available Net Cash" (hereinafter defined) four (4)
times yearly. Such calculations shall be made within fifteen (15) days after the
final day of February, May, August, and November in the manner provided below in
this paragraph 4.5 from receipts and disbursements during the "Calculation
Period" ending on the final day of such months. The results of such calculations
shall be deemed to be the determination of cash available to Rocky Mountain for
payment of Base Rent for the calendar quarter ending on the final day of the
month after such Calculation Period, that is, for the quarters ending March,
June, September, and December, respectively. "Available Net Cash" is defined as:

                (a) Rocky Mountain's fractional share on an acreage basis
(the denominator being the total acreage of all commercial greenhouses then
being operated by Rocky Mountain and Rocky Mountain's Greenhouse Affiliates and
the numerator being total acreage of the Facility) of gross cash receipts during
a given Calculation Period from the sale of agricultural products produced at
the Facility and at all other commercial greenhouse facilities operated by all
of Rocky Mountain's Greenhouse Affiliates (for example, with respect, to the
calendar quarter ended December 31, cross cash receipts for the Calculation
Period comprised of months of September, October, and November); provided, that
insurance proceeds received by Rocky Mountain (directly or indirectly) on
account of damage to or loss of crop from insurance carried pursuant to
paragraph 9.7 shall be included in Available Net Cash without apportionment.

                (b) Less Rocky Mountain's same fractional share (i.e. determined
in the manner provided in clause (a) of this paragraph 4.5) of reasonable cash
expenditures by Rocky Mountain and all of Rocky Mountain's Greenhouse Affiliates
during the same Calculation Period for marketing of the agricultural products 
produced at all such commercial greenhouse facilities; 

                (c) Less Rocky Mountain's same fractional share of reasonable
cash expenditures by Rocky Mountain and all of Rocky Mountain's Greenhouse
Affiliates during the same Calculation Period for general and administrative
purposes which are properly allocable to the production and sale of such
agricultural products;

                (d) Less all other cash expenditures during the same
Calculation Period (i.e. excluding depreciation and amortization) by Rocky
Mountain for ail ordinary and necessary expenses of operating the Facility,
except Base Rent. Repayment of interest and principal on debt which is (i)
reasonably necessary to incur in order to provide for operation of the Facility,
(ii) is used solely to pay ordinary and necessary expenses of operating the
Facility and (iii) is borrowed by Rocky Mountain at rates an on terms not less
favorable to commercial banks doing business in Denver, Colorado (an "Operating
Line of Credit") shall be considered to be an ordinary and necessary expense of
operating the Facility. Repayment of interest or principal on debt which does
not meet the requirements of the preceding sentence shall not be considered to
be an ordinary and necessary expense of operating the Facility, and Rocky
Mountain shall not incur debt

                                      -11-
<PAGE>
 
which does not meet such requirements without Thermo's prior written consent.
Expenses incurred by Rocky Mountain's Greenhouse Affiliates shall not be
considered for purposes of the deduction permitted under this clause (d);
provided, however, that should Rocky Mountain and any of Rocky Mountain's
Greenhouse Affiliates utilize personnel, services, equipment, materials,
facilities, or other non-financial resources in common (other than such of the
foregoing as are utilized for marketing and general and administrative
purposes), or should Rocky Mountain obtain, in conjunction and as joint obligor
with any of Rocky Mountain's Greenhouse Affiliates, an Operating Line of Credit,
the expenditures attributable to such common usage of non-financial resources
and repayment of debt on such common Operating Line of Credit shall be
apportioned equitably among all such commercial greenhouse operators, based on
the relative utilization of such common resource by each such greenhouse
operator, and the allocation thus made to Rocky Mountain shall be deemed, for
purposes of this clause (d), to have been incurred by Rocky Mountain and not by
any of Rocky Mountain's Greenhouse Affiliates. Nothing in this paragraph 4.5
shall be construed: (i) to require that Rocky Mountain obtain a single Operating
Line of Credit in conjunction with one or more Greenhouse Affiliates or
repayment of principal and interest thereon to be considered an ordinary and
necessary expense of operating the Facility, (ii) to require that Rocky Mountain
obtain an Operating Line of Credit rather than establishing a reserve for
working capital, or (iii) to preclude Rocky Mountain from establishing a reserve
for working capital and also obtaining an Operating Line of Credit to the extent
such Operating Line of Credit meets the requirements set forth above in this
clause (d). However, no amounts set aside as a reserve, for working capital
shall be deductible from gross cash receipts for purposes of determining,
Available Net Cash. Rocky Mountain shall not, without Thermo's prior written
consent, directly or indirectly declare or pay any dividend or make any
distribution of cash or other property out of borrowed funds, regardless of
whether such borrowed funds arc obtained from an Operating Line of Credit:
provided, however, that this shall not be construed to prohibit Rocky Mountain
from making matching, dividends or distributions to the extent permitted in
paragraph 1.6 while Postponements of Base Rent are outstanding.

          4.6  Deferral of Base Rent: Limitations on Distributions. In the event
               ---------------------------------------------------            
that, during that portion of the Lease Term which expires on the twentieth
(20th) anniversary of the Commencement Date, operation of the Facility should,
with respect to any calender quarter, fall to generate sufficient Available Net
Cash for payment in full of the installment of Basement due with respect to
such calendar quarter, Rocky Mountain may give to Thermo, not later than ten
(10) days prior to the applicable Quarterly Payment Date, Notice stating Rocky
Mountain's intention to defer payment of all or a portion of the quarterly
installment of Base Rent to become due on such Quarterly Payment Date. Such
Notice shall be accompanied by a complete copy of Rocky Mountain's calculations
showing a deficiency in Available Net Cash for payment in full of Base Rent due
with respect to such calendar quarter and shall be deemed to be a representation
by Rocky Mountain of the completeness and accuracy of such calculations. Such
calculations shall be subject to review and approval by Thermo, which shall not
be withheld unreasonably. Based on such calculations, Rocky Mountain shall have
the right to defer payment of such installment of Base Rent to the extent of the
deficiency in Available Net Cash (each such deferral sometimes herein a
"Postponement"). Each Postponement shall be accounted for separately as a deemed
extension of credit from Thermo to Rocky Mountain, and shall accrue interest
from the time of deferral until the time of payment at the rate of eight percent
(8%) per annum, compounded annually

                                     -12-
<PAGE>
 
with respect to each postponement beginning twelve (12) months after the date of
such Postponement. Under no circumstances shall Rocky Mountain be permitted to
have outstanding accumulated Postponements plus accrued interest thereon of more
than Two Million Five Hundred Thousand Dollars ($2.500.000). Rocky Mountain may
make payments to Thermo of such Postponement(s), plus accrued interest thereon,
in whole or in part at any time without penalty. Should Rocky Mountain desire to
pay any dividends or make any distribution of cash or other property to its
members or other equity owners at any time while any Postponement is
outstanding, Rocky Mountain shall, simultaneously with such dividend or
distribution, make a payment equal to such dividend or distribution for
application against such total Postponement(s) and accrued interest thereon, but
under no circumstances in excess of total Postponement(s) plus accrued interest
then outstanding. The foregoing notwithstanding standing, Rocky Mountain shall,
in addition to Thermal Payments and payments of Additional Rent, also make
payments to Thermo to apply against Postponements (plus accrued interest
thereon) to tile extent that, as of any Quarterly Payment Date, the sum of all
Postponements plus accrued interest then outstanding (including any Postponement
to which Rocky Mountain would otherwise be entitled for the then-current
calendar quarter) exceeds Two Million Five Hundred Thousand Dollars
($2,500,000). For example, should the sum of all Postponements plus accrued
interest thereon as of any Quarterly Payment Date be $2,600,000 (after giving
effect to the regular quarterly payment of Base Rent made on such date) an
additional payment of $100,000 would be required on such Quarterly Payment Date,
thereby reducing he sum of all Postponements plus accrued interest to
$2,500,000 after application of such additional payment. If not sooner paid,
Rocky Mountain shall, beginning on the final day of each calendar quarter
which occurs after the twentieth (20th) anniversary of the initial Date of
Commercial Operation, and continuing on the final day of each calendar
quarter thereafter until all Postponements outstanding on the twentieth (20th)
anniversary of the initial Date of Commercial Operation, together with
interest accruing thereon through the date of payment, shall have been fully
paid, make payments to apply against such Postponements plus accrued interest
thereon in the amount of the quarterly installments of Base Rent provided in
paragraph 4.1, as the same may be adjusted pursuant to the Memorandum
Regarding Adjustment of Rent and Option Price. Such payments shall be in
addition to the Base Rent payments of One Hundred Dollars ($100) per year
required during the final five (5) years of the Lease Term pursuant to
paragraph 4.1. Anything herein to the contrary notwithstanding, should any
Postponement(s) be outstanding (in whole or in part) upon purchase of the
Facility or the entire Leased Premises (i.e. both the Land and the Facility) as
Provided in paragraphs 5.2 and 5.5. below, such Postponements shall become due
and payable, and shall be paid in full, together with accrued interest thereon,
upon closing of such purchase. Further, should any Postponement(s) of Base Rent
(in whole or in part) be outstanding upon final expiration or other termination
of the Lease Term, such deferred amounts shall become due and payable, and
shall be paid in full, together with interest thereon, upon expiration or
termination of the Lease Term.

          4.7 Reserve for Rent Payments: Restriction on Distributions. To the
              -------------------------------------------------------      
extent required of Thermo in the Loan Agreement, Rocky Mountain shall, on each
Quarterly Payment Date, make payments to Thermo for deposit in a cash reserve
account (the "Greenhouse Rent Reserve Account") equal to seventy percent (70%)
of Available Net Cash in excess of amounts required to pay rent hereunder; 
provided, however, that such payments

                                      -13-
<PAGE>
 
shall not be required at any time when the amount on deposit in the Greenhouse
Rent Reserve Account equals or exceeds Base Rent to become due on the next
succeeding four (4) Quarterly Payment Dates. Thermo shall deliver such sums to
the Disbursement Agent provided for under the Loan Agreement (or to any
successor Disbursement Agent) to be held as security for payment of rent
hereunder by Rocky Mountain. Commencing with the first Calculation Period and
continuing until the Greenhouse Rent Reserve Account shall no longer be required
hereunder, Rocky Mountain shall not declare or pay any dividend or make any
distribution of cash or other property at any time while the Greenhouse Rent
Reserve is not fully funded. In the event that Rocky Mountain shall not have
sufficient Available Net Cash to pay all rent due on any Quarterly Payment Date.
Thermo shall return to Rocky Mountain, from the Rent Reserve Account, sums
sufficient to pay such rent, (to the extent of funds then on deposit in the Rent
Reserve Account), and Rocky Mountain shall forthwith remit such sums to Thermo
for payment of rent. Amounts so returned to Rocky Mountain from the Greenhouse
Rent Reserve Account shall be applied to avert Postponements to which Rocky
Mountain would otherwise be entitled under paragraph 4.6 on such Quarterly
Payment Date, but Thermo shall not be entitled to apply funds obtained from the
Greenhouse Rent Reserve Account to reduce Postponements which accrued on prior
Quarterly Payment Dates. Thermo shall also return to Rocky Mountain from the
Greenhouse Rent Reserve Account on each Quarterly Payment Date any balance in
such account in excess of Base Rent to become due on the next succeeding four
(4) Quarterly Payment Dates. Promptly after receipt of the Tax Rate Certificate,
Thermo shall return to Rocky Mountain the difference between 80% of Available
Net Cash in excess of rent deposited for the preceding tax year and the lesser
percentage (but not less than 70%) of Available Net Cash in excess of rent which
Rocky Mountain was obligated to deposit during such tax year as established by
the Tax Rate Certificate. Upon expiration or earlier termination of the Lease
Term, or upon the Greenhouse Rent Reserve Account no longer being required
hereunder, Thermo shall return all funds then on deposit in such account to
Rocky Mountain. Should an alternate form of security for payment of rent by
Rocky Mountain or a reduced amount of such security be acceptable to the party
or parties providing financing for the Plant and/or the Facility, Rocky Mountain
and Thermo shall cooperate to establish such alternate form or reduced amount of
security. Anything in this paragraph 4.7 to the contrary notwithstanding, Thermo
shall also have the right to set off against rent then due from Rocky Mountain
hereunder all sums obtained by Thermo from the Greenhouse Rent Reserve Account,
in lieu of returning such sums to Rocky Mountain for remission to Thermo. Should
Thermo exercise such right of set off it shall promptly advise Rocky Mountain
thereof.

        4.8  Impact of Certain Thermo Financing.  Rocky Mountain's payment 
             ----------------------------------
obligations under this Section 4 are subject to the provisions of paragraph 16 
of the Supplemental Agreement.

5.   PURCHASE BY ROCKY MOUNTAIN
     --------------------------

     5.1 Option to Purchase Facility. Subject to the provisions of paragraph 4
         ---------------------------
of a certain Supplemental Agreement of even date (the form of which is attached
hereto as Appendix II and is hereinafter referred to as the "Supplemental
Agreement"), for a period beginning on the Commencement Date and expiring twelve
(12) years after the Commencement Date, Thermo grants to Rocky Mountain the
right and option ("Purchase Option") to purchase the Facility upon payment of
the Option Purchase Price determined in accordance with Exhibit C and paragraph
5.2; provided, however, that at the time of exercise of the Purchase Option, and
at the time of closing of such purchase, neither Rocky Mountain nor any
Affiliate of Rocky Mountain shall be in default under this Agreement or any
other agreement then existing between Rocky Mountain on any Affiliate of
Rocky Mountain on one hand, and Thermo or any Affiliate of Thermo on the other;
provided, further, that such purchase shall be closed within the time designated
by Rocky Mountain in its Notice of exercise or such extended time as may be
permitted under paragraph 5.5.

     5.2 Exercise of Option: Purchase Price: Closing. Rocky Mountain must
         -------------------------------------------
exercise the Purchase Option, if at all, by notifying Thermo of exercise thirty
(30) days or more prior to the date on which Rocky Mountain desires to accept
title to the Facility, but under no circumstances shall such Notice be given
later than one (1) month prior to expiration of the Purchase Option. If the
Purchase Option is exercised, the purchase shall be closed on the last day of
any calendar quarter designated by Rocky Mountain for closing in the Notice of
exercise, but under no circumstances later than the expiration date of the
Purchase Option as provided in paragraph 5.1. The "Option Purchase Price" shall
be, as of the applicable calendar quarter end, the amount on Exhibit "C"
attached hereto (as adjusted, if required, pursuant to the Rent Adjustment
Memorandum), plus any other payments accrued to Thermo hereunder as of the date
of closing, plus any outstanding Postponements and accrued interest thereon in
accordance with paragraph, 4.6, above, plus any prepayment premium of any nature
which Thermo shall be obligated to pay on the Option Purchase Price (but not on
any other sum prepaid in conjunction therewith) to any third party providing
financing for the Plant and/or the Facility holding a security interest in the
Facility and who shall be entitled to receive proceeds from payment of the
Option Purchase Price in accordance with the loan agreement and supporting
security documents between Thermo and such third party, plus the additional sum
of Ten Thousand Dollars ($10,000). Closing shall occur at the principal office 
of Thermo, or such other mutually convenient location as the parties may 
designate.

     5.3  Title to and Condition of Assets Purchased. At the closing of any
          ------------------------------------------
purchase hereunder, Rocky Mountain shall pay the applicable Option Purchase
Price to Thermo in cash, and Thermo shall convey to Rocky Mountain all of
Thermo's right, title, and interest in the Facility by general warranty deed,
free and clear of all mortgages, liens, and other encumbrances relating to
financing obtained or debts incurred by Thermo, but subject to the continuing
covenants of this Agreement and to the other matters provided in sections 7 and
8 (except paragraph 4.7), which shall be covenants running with the Land for the
benefit of the remaining portion of the Project Site (described in Part II of
Exhibit A) and be enforceable for a period concurrent with the expiration date
of the Thermal Term as if the purchase had not occurred, and subject to those
further matters, if any, then comprising the "Schedule of Permitted
Encumbrances"


                                      -15-
<PAGE>
 
attached hereto as Exhibit H. The foregoing notwithstanding, Thermo may elect to
convey by special warranty deed, in which event Thermo shall purchase and
provide to Rocky Mountain an ALTA Owner's Policy of Title Insurance in the
amount of the applicable Option Purchase Price. Such title insurance policy
shall insure title in Rocky Mountain subject only to standard exceptions
provided in such form and to special exceptions permitted under this paragraph
5.3). Rocky Mountain shall accept such conveyance of the Facility "as is, where
is," and "with all faults," and shall thereafter defend, indemnify and save
Thermo harmless from any losses, Damages or claims arising out of or occurring
in connection with the operation of the Facility except such losses, damages,
and claims as may arise out of the negligent or intentionally tortious acts or
omissions of Thermo, its agents, and employees.

          5.4 Ground Rent if Facility Purchased. In the event that Rocky
              ---------------------------------
Mountain purchases the Facility, Thermo shall, subject to the provisions of
paragraph 5.5, retain the lessor's interest in the Land (i.e. the reversion in
fee), and the Land will thereafter comprise the entirety of the Leased Premises.
In such event, the Lease Term shall continue with respect to the Land only.
Effective on the closing date of such purchase, total Base Rent for the Leased
Premises for the remainder of the Lease Term shall be reduced to an amount equal
to the number of whole or partial months remaining in the Lease Term multiplied
by one percent (1%) of the unencumbered fair market value of the Land
(determined as if there were no improvements thereon) as of the closing date.
Such reduced total Base Rent shall be payable in equal quarterly installments,
in arrears three (3) months after the closing date and on the same day of each
quarter during the remainder of the Lease Term. The amount of each such
installment shall be three percent (3%) of the unencumbered fair market value
of the Land as of the closing date. Additional Rent for the Land during such
period of ground rent only shall consist of real property taxes and assessments
levied with respect to the Land, and shall be paid in the same manner required
for payment of taxes and assessments with respect to the Land and the Facility
pursuant to paragraph 4.2.

        5.5 Purchase of Land: Conditions.  Prior to exercising the Purchase 
            ----------------------------
Option, Rocky Mountain may request that Thermo enlarge the Purchase Option to
encompass the right to also purchase all of Thermo's right, title, and interest
in the Land. Thermo shall do so if Rocky Mountain determines, in Rocky
Mountain's discretion reasonably exercised, that Rocky Mountain is unable to
obtain commercially reasonable financing for purchase of the Facility without
also purchasing the Land, and if Rocky Mountain provides to Thermo reasonable
assurances that if the Purchase Option is enlarged Rocky Mountain will in fact
proceed to purchase the Leased Premises, including the Land. In such event, the
Option Purchase Price for the Leased Premises shall be increased by adding
thereto an amount equal to the unencumbered fair market value of the Land
(determined as if there were no improvements thereon) as of the date the
Purchase Option is exercised, and upon payment of such increased Option Purchase
Price Thermo shall, at the closing, also convey the Land to Rocky Mountain in
the same manner and subject to the terms and conditions provided in paragraph
5.3. Rocky Mountain shall have no right or option to purchase the Land separate
and apart from, or later than, the purchase by Rocky Mountain of the Facility
through exercise of the Purchase Option. Should it become necessary to determine
the fair market value of the Land by appraisal pursuant to paragraph 5.7, the
date for closing may be extended to the extent necessary to complete the
appraisal process.

                                      -16-
<PAGE>
 
        5.6 Certain Obligations to Continue. Should Rocky Mountain purchase
            -------------------------------                              
the entirety of the Leased Premises, i.e. both the Facility and the Land, both
the Lease Term and Rocky Mountain's obligation to pay rent shall cease. The
foregoing notwithstanding, in the event of a purchase, there shall be no
apportionment of any expenses with respect to the property purchased, and Rocky
Mountain shall continue to pay all costs and charges of any nature which Thermo
may become obligated to pay with respect to the Facility, and (if applicable)
the Land and which, but for such purchase by Rocky Mountain, would have been
payable by Rocky Mountain as Additional Rent. Anything herein to the contrary
notwithstanding, all covenants and obligations of this Agreement pertaining
to thermal supply matters (including, without limitation, sections 7 and 8)
shall continue, after termination of the Lease Term as a result of purchase by
Rocky Mountain of either the Facility or the entire Leased Premises, for the
period ending on the date for expiration of the Thermal Term.

        5.7 Valuation by Appraisal. Whenever this Agreement requires that the
            ----------------------                                         
fair market value of the Land be determined as of any particular date, the
parties shall negotiate in good faith to determine such value for a period of up
to thirty (30) days after it becomes apparent that valuation is required. If
they are unable to agree within such period, either party may, by Notice to the
other, demand that the value be determined by appraisal. The party demanding
appraisal shall, at the time such demand is made, designate a professional real
estate appraiser to perform such appraisal. If such appraiser is not acceptable
to the non-designating party, the non-designating party shall, within ten (10)
days after demand for appraisal is made, designate a second professional
appraiser. If such second professional appraiser is acceptable to the party
having first demanded appraisal, the appraisal shall be performed by the second
appraiser so designated. Otherwise, both parties (or, should the parties be
unable to agree, the two previously designated appraisers) shall, within ten
(10) days after the second appraiser is designated, designate a third appraiser,
and the three (3) appraisers shall, within thirty (30) days after the third
appraiser is designated, jointly determine the fair market value of the Land, on
an unencumbered and unimproved basis, and render a written report of such
determination to both parties. The appraisers shall attempt to determine value
by consensus, but if they are unable to do so the fair market value of the
property appraised shall be deemed to be the average of their separate
valuations; provided, however, that if two of the three appraisers' valuations
are within ten percent (10%) of each other, and the third appraiser's valuation
is more than ten percent (10%) different from either of the other two
valuations, the valuation which is more than ten percent (10%) different shall
be disregarded. All appraisers shall be independent of either party and shall be
persons having not less than ten (10) years' experience in appraisal of
commercial and industrial real property in the Counties of Weld, Denver,
Boulder, and Adams, Colorado, or if less experienced in the local market shall
hold the then-current designation of Member of the Appraisal Institute ("MAI"),
Society of Industrial Realtors ("SIR"), or other professional appraiser
designation of comparable stature and qualification. Costs and expenses of
appraisal shall be borne equally by Thermo and Rocky Mountain. If any other
transaction in property sold or leased by thermo on or in the vicinity of the
Project Site shall be considered by the appraisers as a comparable transaction,
the appraisers shall analyze and take into consideration, when evaluating such
comparable transaction, the impact of any thermal energy sales contracts or
agreements entered into with Thermo in connection with such transaction.

          5.8 Mortgage to Secure Performance. Upon closing of any purchase
              ------------------------------
provided for in this section 5, whether of the Facility alone or of the entire
Leased Premises, should any party providing financing to Thermo so request,
Rocky Mountain shall execute and deliver to Thermo a Mortgage of the Facility
(and if applicable the Land) in substantially the form attached hereto as
Exhibit "D" (the "Mortgage"), in order to secure to Thermo performance by
Rocky Mountain of each and every obligation by Rocky Mountain hereunder which
will survive such purchase by Rocky Mountain. The Mortgage shall be 
subordinated in priority to a deed of trust or other financing encumbrance
granted by Rocky Mountain to secure repayment by Rocky Mountain of purchase
money paid to Thermo; or to secure funds advanced to Rocky Mountain from time
to time by a recognized commercial bank or other institutional lender for
working capital purposes; provided, however, that such subordination shall
provide that the Mortgage shall survive foreclosure of any such deed of trust or
other financing encumbrance to which the Mortgage is subordinated, and that any
purchaser of the former Leased Premises at foreclosure shall take title
subject to the terms of the Mortgage. Thermo may assign the Mortgage and all
of its rights thereunder to any party providing financing to Thermo for the
Plant and/or the Facility.

        5.9 Impact of Certain Thermo Financing.  Rocky Mountain's rights under
            ----------------------------------
this section 5 are subject to the provisions of paragraph 4 of the Supplemental
Agreement.


     6. CONSTRUCTION OF FACILITY
        ------------------------

        6.1 Acceptance of Site. Prior to signing this Agreement, Rocky Mountain 
            ------------------
has visited the Project Site and has examined the Land to its satisfaction.
Rocky Mountain has also obtained such zoninq and other land use regulation
information, soils and subsurface investigation information, and information
with respect to present or prospective availability of utilities, including
without limitation water, sewerage, waste disposal, natural gas, and
electricity, and such other information with respect to the Project Site as
Rocky Mountain deems prudent. Rocky Mountain agrees to commence construction on
the Land pursuant to paragraph 6 4 "as is" (or as shall have been placed by
"Owner" pursuant to the Construction Contract) and to accept possession of the
Land on the Commencement Date as the Land shall be improved pursuant to this
Agreement. Rocky Mountain agrees to make no claims against Thermo with respect
to the physical condition of the Project Site or the Land, and agrees to save,
indemnify and hold Thermo harmless from any such claims asserted by Affiliates
of or persons claiming under Rocky Mountain.

          6.2 Preliminary Plans and Schedule. Attached hereto (or incorporated
              ------------------------------                                
by reference) as Exhibit E are preliminary drawings and an outline construction
specification for the Facility (the "Preliminary Plans") which have been
furnished by Rocky Mountain. Thermo shall review the Preliminary Plans promptly
to the extent that they provide for interface between the Facility and the
Plant, and shall give Notice to Rocky Mountain within fifteen (15) days after
the effective date stating whether or not the Preliminary Plans are satisfactory
to Thermo for such purposes. Any such Notice shall specify the reasonable
revisions (if any) with respect to interface matters which Thermo requires. In
all other aspects, the Preliminary Plans are agreed by the parties to be
satisfactory. Also attached hereto (or incorporated by reference) as

                                      -18-
<PAGE>
 
Exhibit F is a "Preliminary Construction Schedule" showing the approximate time
which Rocky Mountain has estimated will be required to construct the Facility.
Based on the Preliminary Plans and the Preliminary Construction Schedule, Thermo
has familiarized itself generally with the nature and scope of the Work required
to construct the Facility. Both parties have considered the Preliminary Plans
and the Preliminary Construction Schedule in determining the time for completing
the Facility and for giving Notice to Proceed pursuant to paragraph 6.4.

          6.3 Construction Plans: Changes. Within sixty (60) days after the
              ---------------------------
later of either Financial Closing or the delivery by Thermo of Notice to Proceed
(accompanied by any "Notice to Proceed Payment" required in the Construction
Contract) Rocky Mountain shall cause to be prepared and delivered to Thermo
Construction Plans. The Construction Plans shall be satisfactory in all respects
to Rocky Mountain, and shall be consistent with the Preliminary Plans. Thermo
shall promptly review the Construction Plans and shall have the right to require
reasonable changes in the Construction Plans in order to ensure that the
Facility will permit the Plant to attain and retain "Qualifying Facility" ("QF")
status for purposes of the Public Utility Regulatory Policies Act of 1978 (also
referred to herein as "PURPA") and to provide for proper interface between the
Facility and the Plant, but not to increase the size or scope of the Facility.
Rocky Mountain shall promptly cause such reasonable changes required by Thermo
to be made to the Construction Plans and shall resubmit the Construction Plans
to Thermo. Thermo shall not withhold or delay approval of the Construction Plans
nor shall Thermo require changes to the Construction Plans which would
materially change the size of the Facility or the scope of the "Work" (as
defined in the Construction Contract). Under no circumstances shall Rocky
Mountain be required or permitted to make any change in the Work which would
make the Facility materially less satisfactory for commercial agricultural
purposes. Upon approval by Thermo of the Construction Plans they shall be
incorporated by reference into the Construction Contract. Thermo and Rocky
Mountain acknowledge that the Construction Contract gives both parties the
authority to make certain changes to the Work after the Construction Plans have
been initially approved, subject to Thermo's prior approval of any change which
would downsize the Facility, affect Facility/Plant interface, impair QF status
for PURPA purposes, impair Plant qualification under applicable on-system power
purchase agreements with a public utility, or materially increase the "Cost of
the Work" (as defined in the Construction Contract) when compared to the Work
Budget (in its original form) which is attached to the Construction Contract.
For purposes of such provisions, changes of not more than $25,000.00 for any
single change or more than $100,000.00 for all such changes (taken in the
aggregate) ordered by Rocky Mountain shall be deemed not to materially increase
the Cost of the Work. Subject to the foregoing, Rocky Mountain shall retain full
responsibility for the Facility design and for the sufficiency and integrity of
all plans and specifications which are used for construction of the Facility.
Rocky Mountain agrees to make no claims against Thermo with respect to the
design of the Facility, such plans and specifications, or the suitability of
the Facility, as finally constructed and occupied, for use as a commercial
greenhouse as required by this Agreement.

          6.4 Construction Contract: Completion. Contemporaneously herewith
              ---------------------------------                          
Thermo and Rocky Mountain have entered into a construction contract in
substantially the form attached hereto as Exhibit F the ("Construction
Contract"). The Construction Plans shall be incorporated by reference into the
Construction Contract promptly after the Construction Plans have been delivered
to Thermo by Rocky Mountain

                                      -19-
<PAGE>
 
and have been approved by Thermo. Not less than eight (8) months prior to the
date on which Thermo anticipates that the initial Date of Commercial Operation
of the Plant shall occur, Thermo shall give "Notice to Proceed" to the
Contractor under the Construction Contract, accompanied by any Notice to Proceed
payment required by the Construction Contract. Rocky Mountain, acting as
Contractor, shall thereupon proceed expeditiously to construct the Facility
pursuant to the Construction Contract so as to achieve Substantial Completion
not later than eight (8) months after Notice to Proceed is given, subject to
extension as expressly provided in the Construction Contract (the "Completion
Date"). The Completion Date shall also be subject to extension to the extent
that the anticipated initial Date of Commercial Operation provided in paragraph
3.1 is extended. Both Thermo and Rocky Mountain shall use their best efforts to
coordinate their respective construction activities on the Project Site in such
a manner to avoid materially impeding each other with respect to completion of
the Plant and the Facility. All vendors and subcontractors for the Facility
proposed to be engaged by Rocky Mountain acting as Contractor shall be subject
to review and prior approval by Thermo. Subject to active interference with the
prosecution of the Work which materially delays Rocky Mountain acting as
Contractor and is caused solely by Thermo or any person having a direct contract
with Thermo for construction of the Plant, Rocky Mountain, acting as Contractor,
shall (and hereby does) guarantee to Thermo that the Facility shall be
Substantially Complete and ready for use, and occupancy, not later than the
Completion Date. Should the "Project Manager" under the Construction Contract
notify Thermo that it appears to the Project Manager, after due investigation
and consultation with Rocky Mountain that Rocky Mountain is not proceeding so as
to cause the Facility to be Substantially Complete by such Date, Thermo may,
subject to such rights of cure as are provided under the Construction Contract,
exercise its rights under the Construction Contract to declare Rocky Mountain in
default thereunder and, at Thermo's option, terminate the Construction Contract
or, without terminating the Construction Contract, finish the Work as provided
in the Construction Contract. This paragraph 6.4 is subject to the provisions
for extension of time provided in the Construction Contract.

          6.5 Contract Sum. The "Contract Sum" under the Construction Contract
              ------------
shall be the "Cost of the Work" as defined thereunder, plus a "Contractor's Fee"
as provided in the Construction Contract. For purposes of estimating the Base
Rent provided in paragraph 4.1, the Contract Sum has been estimated at Seven
Million Eight Hundred Thousand Dollars ($7,800,000). The Contract Sum shall be
disbursed by Thermo to the Contractor in a timely manner in accordance with the
requirements of the Construction Contract.

     7.   THERMAL SUPPLY
          --------------

          7.1 Thermal Energy Commitment - Minimum Level. Thermo shall use
              -----------------------------------------                  
reasonable efforts to cause the Plant to be constructed as herein provided.
Thermo plans that as constructed the Plant will be capable of generating
available thermal energy of not less than sixty million (60,000,000) BTU per
hour. Thermal energy shall be made available to and shall be accepted by Rocky
Mountain at a heat transfer subsystem which shall be constructed by Thermo and
shall constitute a portion of the Plant. Thermal energy shall then be
transmitted to the Facility by means of a self-contained, closed system
circulating hot water loop which shall be part of the Facility. The heat
transfer subsystem shall be reasonably satisfactory to Rocky Mountain and shall
include (but not

                                      -20-
<PAGE>
 
be limited to) interface equipment which will facilitate the prompt connection
to the heat transfer subsystem of temporary steam boiler equipment in the event
of need to utilize temporary sources of thermal energy to supply thermal energy
to the Facility. The heat transfer subsystem shall be located in reasonable
proximity to the boundary of the Land but shall not be located on the Land.
Rocky Mountain shall at all times have satisfactory access to the heat transfer
subsystem for the purpose of connecting thereto such temporary sources of
thermal energy as may be required pursuant to paragraph 7.4, below. After the
Plant is constructed, Thermo shall continually use its best efforts to make
available for use by Rocky Mountain, beginning on the initial Date of Commercial
Operation and extending for a period of twenty-five (25) years thereafter, a per
annum quantity of thermal energy generated through operation of the Plant of not
less than Two Hundred Billion (200,000,000,000) BTU, net of condensate loss at
the heat transfer subsystem, measured annually on a calendar year basis (the
"Minimum Annual Heat Requirement"); provided, however, that for any partial
calendar year in which the Thermal Term of this Agreement shall be in effect,
the Minimum Annual Heat Requirement shall be Two Hundred Billion
(200,000,000,000) BTU multiplied by a fraction, the numerator of which shall be
the number of days in such partial calendar year and the denominator of which
shall be three hundred sixty-five (365). The Plant shall include an instrumenta-
tion system, satisfactory to both Thermo and Rocky Mountain, for continuous
measurement and metering of the thermal energy made available by Thermo and
accepted by Rocky Mountain at the heat transfer subsystem. Both parties to this
Agreement shall have continuous access to such instrumentation system at all
reasonable times for the purposes of monitoring and recording thermal energy
available to and accepted by Rocky Mountain and inspecting the instrumentation
system. Maintenance, testing, and adjustment of the instrumentation system shall
be the responsibility of Thermo. Thermo shall test and calibrate the
instrumentation system from time to time as reasonably requested by Rocky
Mountain, but not less than is necessary to ensure accuracy and measurement of
available and accepted thermal energy. Rocky Mountain shall defend, indemnify
and save harmless Thermo and the other persons who constitute Indemnitees under
paragraph 10.1 below, from any liabilities, costs, expenses, or Damages
resulting from entry on to Project Site by Rocky Mountain, its agents, employees
and contractors, for purposes of obtaining access to the heat transfer subsystem
and the heat transfer instrumentation system.

        7.2   Thermal Energy Commitment - Additional Level. Upon not less than
              ---------------------------------------------
seven (7) days' advance request by Rocky Mountain, Thermo may make available to
Rocky Mountain quantities of thermal energy in excess of the Minimum Annual
Heat Requirement, and Thermo shall do so if it is consistent with Plant
operating requirements (which shall include, without limitation, the
requirements of on system power purchase agreements) and the utilization of or
commitments to make thermal energy available to other thermal users (if any)
served by Thermo who may from time to time conduct operations on or in the
vicinity of the Project Site.

        7.3   Manner of Furnishing Thermal Energy. Not less frequently than
              ------------------------------------                        
before noon of each Monday during the Thermal Term, Rocky Mountain shall
prepare and furnish to Thermo a written forecast of Rocky Mountain's expected
minimum daily requirements for thermal energy during the ensuing seven (7) day
period which begins at 8:00 a.m. on the first Tuesday following the day the
forecast is delivered. This forecast shall be updated by Rocky Mountain verbally
or in writing as often as may be reasonable and practical for Rocky Mountain to
do so in order to take into consideration

                                      -21-
<PAGE>

anticipated changes in operating conditions, including without limitation
expected changes in weather which would materially increase Rocky Mountain's
thermal energy requirements. Based on the forecasts of heat requirements and the
supplemental heat requirements information which Rocky Mountain shall have
provided to Thermo in a timely manner, Thermo shall operate the Plant in a
manner which will result in the Minimum Annual Heat Requirement being made
available to Rocky Mountain during each calendar year substantially in
accordance with such forecasts and supplemental information. In the event that,
after reasonable prior notice of Rocky Mountain's heat requirements Thermo
should fail to make available thermal energy from operations of the Plant
substantially in accordance with Rocky Mountain's forecasts and supplemental
heat requirements information (within the limits of 60,000,000 BTU per hour and
not in excess of the Minimum Annual Heat Requirement in any calendar year),
Thermo shall make thermal energy available to Rocky Mountain, in a timely manner
and substantially in accordance with Rocky Mountain's forecasts, from alternate
sources arranged by Thermo at Thermo's expense, and should Thermo fail to do so,
Thermo shall be liable to Rocky Mountain as hereinafter provided in paragraph
7.4.

        7.4   Temporary Sources of Thermal Energy. Should Thermo fail to furnish
              ------------------------------------                             
thermal energy in accordance with paragraph 7.3 on a timely basis after demand
by Rocky Mountain, Rocky Mountain shall, to the extent it is reasonably
practical to do so, attempt to obtain temporary alternate sources of thermal
energy and charge Rocky Mountain's costs in connection therewith to Thermo.
Should Thermo become aware of impending condition(s) which are likely to
materially impair Thermo's ability to furnish, thermal energy as required under
paragraph 7.3, Thermo shall give notice (verbally or in writing) of such
conditions to Rocky Mountain as soon as it is practical to do so. Should Rocky
Mountain be able, in the exercise of reasonable diligence, to obtain and utilize
such temporary alternate sources of thermal energy the actual incremental cost,
(i.e. the cost in excess of Fifty Cents ($.50) per One Million BTU) to Rocky
Mountain of obtaining thermal energy from alternate sources shall be paid by
Thermo and be compensation in the nature of liquidated damages, as Rocky
Mountain's sole remedy in such event. Further, should the Facility be
constructed or modified to include permanent standby heat generating or heat
storage equipment reasonably satisfactory to Rocky Mountain, Rocky Mountain
shall be responsible for operating such equipment in the event that Thermo
should fail to furnish thermal energy, and the actual incremental cost (i.e. the
cost in excess of Fifty Cents ($.50) per One Million BTU produced) of operating
such equipment in a manner which will avoid loss or material damage to Rocky
Mountain's crop because of failure by Thermo to supply thermal energy as herein
required shall also be compensation in the nature of liquidated damages in lieu
of the liquidated damages specified in the preceding sentence. At any time
during the Thermal Term, Thermo shall have the right to install, or to cause
Rocky Mountain to install, such permanent standby heat generating or heat
storage equipment in the Facility at Thermo's expense. The parties agree that in
the event that Rocky Mountain should receive less than ninety-six (96) hours'
prior notice (written or verbal) from Thermo that Thermo will not be able to
furnish thermal energy to Rocky Mountain in a timely manner (i.e. as and to the
extent contemplated under paragraph 7.3), Rocky Mountain's ability to arrange
for temporary sources of thermal energy in sufficient time to avert probable
damage to Rocky Mountain's crop may be materially impaired. Should Rocky
Mountain be unable, in the exercise of reasonable diligence, to obtain temporary
alternate sources of thermal energy under such circumstances, and if the
Facility does not then include permanent standby heat generating or heat storage
equipment, then Rocky Mountain shall be entitled to seek


                                      -22-
<PAGE>
 
recovery of its Damages resulting from failure by Thermo to supply thermal
energy as herein required; provided, however, that (i) so long as Thermo shall
have paid or reimbursed premiums for a policy of insurance insuring the risk of
damage to crop because of loss of heat as further described in paragraph 9.7,
below, or (ii) Rocky Mountain shall have obtained a policy of such insurance as
permitted under paragraph 9.7, (a) Rocky Mountain shall not be entitled to claim
a breach or default under this Agreement because of failure by Thermo to furnish
thermal energy as herein required; and (b) Rocky Mountain shall have no claim
for loss or damages of any nature arising out of such occurrence except to the
proceeds of such insurance (whether such proceeds are payable directly to Rocky
Mountain as named insured or to Thermo as indemnification or Thermo's liability
to Rocky Mountain under such circumstances). Thermo shall reimburse Rocky
Mountain for any deductible under such insurance which actually diminishes
recovery by Rocky Mountain under such circumstances.

        7.5   Use and Operation of Facility: Use of Thermal Energy.  As an
              -----------------------------------------------------            
essential term of this Agreement, Rocky Mountain shall use and operate the
Facility only as a greenhouse for commercial production of agricultural
products, or for such alternative uses (which may not be implemented prior to
Thermo obtaining certification by the Federal Energy Regulatory Commission that
such altered use will continue to qualify the Plant as a QF, and must in any
event require consumption of sufficient useful thermal energy for the Plant to
remain a QF) as may be approved by Thermo prior to any change of use. Thermo
shall not withhold or delay approval unreasonably. Rocky Mountain shall, in
connection with operation of the Facility, provide to Thermo forecasts pursuant
to paragraph 7.3 calling for at least One Hundred Percent (100%) of the minimum
Annual Heat Requirement to be consumed each calendar year beginning with the
year in which the initial Date of Commercial Operation occurs. Unless it is
impossible for Rocky Mountain to do so (and notwithstanding the provisions of
paragraph 7.7 below), Rocky Mountain shall accept One Hundred Percent (100%) of
the Minimum Annual Heat Requirement, plus any additional thermal energy made
available by Thermo to Rocky Mountain upon Rocky Mountain's request,and shall
utilize such Minimum Annual Heat Requirement provided by Thermo for useful
thermal purposes in accordance with rules and regulations from time-to-time
promulgated and in effect under PURPA and any amendment thereof; provided,
however, that this sentence shall not be construed to require use of the
Facility for purposes other than a commercial greenhouse. Rocky Mountain shall
request additional thermal energy from Thermo prior to obtaining or generating
thermal energy for such agricultural production purposes (or approved alternate
useful thermal purposes) from any other source. Rocky Mountain shall refrain
from utilization of any other source of thermal energy (except solar generated
radiant energy) in connection with activities conducted at the Facility so long
as Thermo is able to make available thermal energy to Rocky Mountain sufficient
to satisfy Rocky Mountain's needs. Should Thermo be unable to supply from Plant
operations all of Rocky Mountain's requirements for thermal energy at any time,
Rocky Mountain shall nevertheless be obligated to accept and use, in the manner
herein provided, such portion of Rocky Mountain's requirements as Thermo is able
to and does supply from Plant operations.

        7.6   Thermal Payments. Subject to paragraph 7.7 below, beginning
              -----------------                                         
with the last day of the first complete calendar quarter after the initial Date
of Commercial Operation shall have occurred, and continuing for the entire
Thermal Term, Rocky Mountain shall pay to Thermo Fifty Cents ($.50) Per One
Million (1,000,000) BTU (or portion thereof) of Thermal Energy made available
pursuant to Rocky Mountain's

                                      -23-
<PAGE>
 
forecasts under paragraph 7.3 up to the Minimum Annual Heat Requirement, and One
Dollar ($1.00) per One Million (1,000,000) BTU (or portion thereof) for thermal 
energy requested by Rocky Mountain and supplied by Thermo pursuant to paragraph 
7.2 in excess of the Minimum Annual Heat Requirement by Thermo to Rocky Mountain
during such calendar quarter.  Such quarterly payment obligations are herein 
referred to as "Thermal Payments."  On every January 1 beginning with the second
complete calendar year after the initial Date of Commercial Operation, such 
rated per MMBTU shall be adjusted by multiplying the rates in effect during the 
preceding calendar year by one hundred three percent (103%).  Thermal Payments 
shall be due and payable within thirty (30) days after receipt by Rocky Mountain
of Thermo's invoices for such thermal energy. Rocky Mountain's payment
obligations under this paragraph 7.6 are subject to paragraph 16 of the
Supplemental Agreement.

        7.7  Force Majeure.  The obligations of Thermo to supply thermal energy 
             -------------
hereunder shall be suspended for so long as Thermo is prevented from performing
such obligations by an act of God, strike, fire, flood, explosion, disease,
blight, pestilence, or any other cause of the kind specifically enumerated in
this sentence hereinafter a condition of "Force Majeure"). The obligations of
Rocky Mountain to make Thermal Payments hereunder shall be suspended for so long
as Rocky Mountain is prevented because of conditions of Force Majeure from
utilizing the Facility for commercial production of agricultural products. The
foregoing notwithstanding, no occurrence or circumstances shall give rise to a
condition of Force Majeure unless such occurrence or circumstances are not
reasonably within the control of and could not, in the exercise of reasonable
diligence, have been avoided by the affected party, and under no circumstances
shall a condition of Force Majeure be deemed to exist solely because of
operational or business circumstances which would require the affected party to
carry on its operations under this Agreement at an economic loss. Such
operational or business circumstances might include, by way of example and
without limitation, lack of demand for or fluctuations in the price of
electricity, fluctuations in the price of fuel and other costs of operation the
Plant, lack of demand for or fluctuations in the price of agricultural products,
and fluctuations in the costs of operating the Facility. Both parties shall use
best efforts to cause all conditions of Force Majeure to be alleviated as soon
as is reasonably practical (and in any event in not more than thirty (30) days),
but nothing herein shall be construed to require the settlement of strikes or
labor disputes in any manner or at any time other than in a manner and at a time
which is within the discretion of the party affected thereby. Further
notwithstanding the foregoing, and without regard to the existence of any
condition of Force Majeure, Rocky Mountain shall continue to accept and utilize
for useful thermal purposes thermal energy made available by Thermo in
accordance with the requirements of this section 7 unless it is impossible for
Rocky Mountain to do so, and then only to the extent of such impossibility.

        7.8  Duration of Covenants.  Notwithstanding any earlier purchase by 
             ---------------------
Rocky Mountain of the Facility (and if applicable the Land), Thermo and Rocky 
Mountain shall be and remain obligated to each other as provided in this section
7 for the Thermal Term, which shall begin on the Commencement Date and shall 
expire twenty five (25) years after the initial Date of Commercial Operation of 
the Plant.  Should Rocky Mountain purchase the Facility (and if applicable the 
Land), the provisions of this section 7 shall constitute covenants running with 
the Land and with the portion of the Project Site described in Part II of 
Exhibit A, and be binding for such twenty-five (25) year period on Rocky 
Mountain and Thermo, and their respective successors-in-title to the Land and 
the portion of the Project Site described in Part II of Exhibit A.

                    8.1    No Other Activities. Rocky Mountain has not 
                           --------------------
heretofore engaged, and shall refrain from engaging, in any business or activity
other than the development, construction, equipping and operation of the
Facility in compliance with this agreement and the adjunct agreement entered
into pursuant to this Agreement.

                    8.2    Compliance with Law Generally. Rocky Mountain agrees 
                           ------------------------------           
that the Facility and the Land shall be used and occupied for the purposes
provided in paragraph 7.5 in a careful, safe, and proper manner, that no
activity which is known in the insurance industry as extra or especially
hazardous shall be permitted therein, and that no waste shall be committed or
suffered by Rocky Mountain to the Leased Premises. Rocky Mountain shall at all
times comply with all laws, ordinances, and lawful regulations of federal,
state, and local governmental authorities having jurisdiction over the Facility
and the Land. Rocky Mountain shall at all times maintain in force and effect all
permits and licenses, if any, required for the operation of the Facility as a
commercial greenhouse. except such permits and licenses as apply to the Plant
and the Facility jointly, which shall be obtained and maintained by Thermo.

                    8.3    Environmental Compliance. Without limitation of 
                           -------------------------
paragraphs 5.3, 8.2, or 10.1, Rocky Mountain shall at all times comply fully
with all laws, rules, regulations and ordinances now existing or hereafter
enacted of any public authority having jurisdiction with respect to the storage,
use, or release of "Materials of Environmental Concern" at the Facility and on
the Land. For purposes hereof, "Materials of Environmental Concern" shall mean
chemicals, pollutants, contaminants, wastes, degradation by-products, toxic
substances, petroleum and petroleum products, including without limitation
"hazardous substances," "hazardous wastes," "toxic substances," and "toxic
pollutants," as defined in or identified pursuant to any "Environmental Laws."

                    8.4    Clean and Orderly Appearance. Rocky Mountain shall 
                           -----------------------------   
at all times keep the Facility and the Land in a clean, neat, and orderly
condition typical of a well managed commercial greenhouse, shall cause trash and
refuse to be stored out of view of the general public and the adjoining
property, and shall cause such trash, refuse, and other waste products to be
removed on a regular basis. Rocky Mountain shall keep all parking and walkway
areas on the Land clean, orderly, and reasonably free from snow, ice, and
debris. This paragraph 8.4 is subject to the provisions of paragraph 7 of the
Supplemental Agreement.

                    8.5    Repairs and Maintenance. Rocky Mountain shall from 
                           ------------------------              
time to time make, at Rocky Mountain's expense, all necessary interior and
exterior repairs and replacements to the Facility and all parts thereof, and
shall perform all necessary interior and exterior maintenance to the Land, the
Facility and the other improvements thereon, including without limitation the
landscaped areas, drives, parking areas, aprons, and sidewalks constituting a
part thereof. Such duty to make repairs shall include all structural and
nonstructural repairs and all partial or complete replacements of Facility

                                      -25-
<PAGE>

components and building systems which may become necessary or advisable during
the Thermal Term of this Agreement in order for the Plant to be and remain a
Qualifying Facility because of supply of useful thermal energy to the Facility
pursuant to this Agreement; provided, however, that nothing in this paragraph
8.5 shall be construed to require Rocky Mountain to make modifications to or
alterations of the Facility, as distinguished from repairs or replacements of
the Facility or components thereof. Should Thermo be entitled to any guarantees
or warranties with respect to the Facility from contractors or vendors, Thermo
shall assign such guarantees and warranties to Rocky Mountain. Should changes in
PURPA or the regulations promulgated thereunder subsequent to the Effective Date
impose materially more rigorous standards of maintenance of the Facility for the
Plant to be and remain a QF than is then customary for maintenance of similar
commercial greenhouses by prudent greenhouse operators, such more rigorous
requirements shall be deemed to be a PURPA-mandated alteration of the Facility
and to be subject to paragraph 8.6. This paragraph 8.5 is subject to the
provisions of paragraph 7 of the Supplemental Agreement.

                    8.6    Alterations of Facility: When Permitted and Required.
                           ---------------------------------------------------- 
After providing not less than thirty (30) days' prior Notice to Thermo
accompanied by Construction Plans for such work, Rocky Mountain may make such
changes to the Facility and the, Facility systems as Rocky Mountain from time to
time require or deem appropriate in Rocky Mountain discretion to adapt the same
to Rocky Mountain's reasonable requirements for the commercial production of
agricultural products or such other uses as may be permitted under paragraph
7.5, above; provided, however, that no such change shall impair or diminish in
any material manner Rocky Mountain's ability to discharge fully all obligations
under section 7; provided, further, that no such change shall adversely affect
the status of the Plant as a Qualifying Facility; and provided, further, that
Thermo shall not have objected to such work within such thirty (30) day period.
Should Thermo not object to such work within such thirty (30) day Period, such
work shall be commenced and thereafter completed expeditiously by Rocky Mountain
in accordance with the Construction Plans submitted by Rocky Mountain. Thermo
shall have the right to witthhold approval of such alterations and such
Construction Plans if the alterations to be made do not meet the foregoing
requirements of this paragraph 3.6. If Thermo withholds approval of Construction
Plans as provided in the preceding sentence, Rocky Mountain shall not proceed
with the proposed alteration, but shall have the right to resubmit revised
Construction Plans which meet the foregoing requirements for Thermo's approval.
Should changes in PURPA or in the rules and regulations promulgated thereunder
subsequent to the Effective Date require modifications in the design, size, or
equipment of the Facility in order for thermal energy supplied to the Facility
by Thermo to be deemed (for PURPA purposes) to be utilized by Rocky Mountain for
a useful thermal purpose or for the Plant to retain (or regain) QF status,
Thermo and Rocky Mountain shall promptly negotiate to determine the scope and
costs of such modifications. At Thermo's request, Rocky Mountain shall thereupon
promptly commence and complete the modifications in design, size, or equipment
of the Facility which are required because of changes in PURPA or rules and
regulations promulgated thereunder) for thermal energy supplied to the Facility
by Thermo to be deemed (for PURPA purposes) to be utilized by Rocky Mountain for
a useful thermal purpose, or for the Plant to retain (or regain) QF status, or
if Rocky Mountain declines to do so Rocky Mountain shall promptly permit Thermo
to do so. Such work shall be performed in an expeditious manner so as to
minimize any period of time during which the Plant shall not be entitled to QF
status pending completion of such modifications and so as to minimize disruption
of agricultural
                                      -26-
<PAGE>
 
production by Rocky Mountain. Regardless of which party proceeds with such
modifications, Thermo shall pay all capital costs associated with such
modifications. If the Purchase Option remains in effect at that time, Exhibit C
shall be modified to reflect an increase in the Base Purchase Price equal to the
fully allocated cost of such additional investment by Thermo. The foregoing
notwithstanding, if the Facility shall have been purchased by Rocky Mountain and
thereafter modifications shall be required for PURPA compliance purposes, Thermo
may request that Rocky Mountain pay the costs of such modifications in lieu of
payment by Thermo, and should Rocky Mountain decline to do so Thermo may pay
such costs as hereinabove provided, and, if such costs exceed a total of Five
Hundred Thousand Dollars ($500,000), at Thermo's option the purchase and sale
of the Facility to Rocky Mountain shall be rescinded, the Option Purchase Price
actually paid shall be refunded to Rocky Mountain, Rocky Mountain shall reconvey
the Facility (and if applicable the Land) to Thermo in the same manner as is
provided in paragraph 5.3, above, and all provisions of this Agreement which had
become inapplicable because of such prior purchase shall be reinstated, except
for the provisions of section 5. In the event of such reconveyance, Thermo shall
also have the right to terminate this Agreement, including the Thermal Term and
the reinstated Lease Term, upon six (6) months' Notice to Rocky Mountain.

                    8.7    Alterations of Facility: How Effected. All 
                           --------------------------------------
alterations, additions and improvements made by Rocky Mountain (whether or not
Thermo's prior consent is required) shall be effected in a good and workmanlike
manner and subject to prior purchase of the Facility by Rocky Mountain, shall
become the absolute property of Thermo upon expiration or termination of Rocky
Mountain's leasehold or the abandonment of the Leased Premises by Rocky Mountain
unless Thermo elects to require Rocky Mountain to remove the Facility at such
time. Nothing herein shall be construed to constitute Rocky Mountain as the
agent of Thermo for purposes of making any such alterations, additions, or
improvements or to give Thermo any control over the manner of execution of the
work, it being agreed that Rocky Mountain and Rocky Mountain alone is fully
responsible for completion of all such alterations, additions, and improvements.

                    8.8    Discharge or Liens. Rocky Mountain shall defend,
                           -------------------   
indemnify and hold Thermo and Thermo's interest in the Facility and the Land
harmless from all liens and claims of liens which may be filed or claimed in
connection with any construction repairs, maintenance, alterations, additions,
improvements, or other work made or done by Rocky Mountain on the Facility or
the Land. Upon Thermo's demand, any liens filed against the Facility or the Land
(or against other portions of the Project Site or any improvements thereon)
arising out of or under the Construction Contract or any subcontract (at any
tier) thereunder, or out of any alterations, additions, improvements, or other
work by Rocky Mountain in or on the Leased Premises, shall immediately be
removed by Rocky Mountain, at Rocky Mountain's sole expense, or, if Rocky
Mountain desires to contest the same, Rocky Mountain shall have the right to do
so provided that such contest does not produce a material risk that the Project,
the Facility, the Land, or any significant part thereof, title thereto, or any
significant interest therein may be sold, lost, or forfeited, or the use thereof
interfered with, and provided further that Rocky Mountain shall have posted a
bond for the full amount of such liens. Should any third party providing
financing for the Plant and/or The Facility require Thermo to adhere to more
rigorous standards with respect to the discharge (or bonding) of liens, Rocky

                                      -27-
<PAGE>
 
Mountain shall adhere to such more rigorous standards promptly after Thermo
shall have given Notice to Rocky Mountain of such more rigorous standards.

                    8.9    Utilities. Rocky Mountain, at its expense, shall 
                           ----------
obtain and pay for all necessary or required utilities and other services for
the Facility and the Land. The foregoing notwithstanding, at Rocky Mountain's
request and in lieu of Rocky Mountain obtaining water directly from the City of
Fort Lupton, Thermo shall furnish to Rocky Mountain such reasonable quantities
or raw and/or treated water as shall be available to Thermo and as Rocky
Mountain may reasonably require for operation of a commercial greenhouse in the
Facility in excess of Thermo's requirements from time to time for operation of
the Plant. Thermo shall invoice Rocky Mountain quarterly for Thermo's fully
allocated costs (including without limitation capital investment costs but
without any allocation of general and administrative expenses or allowance for
profit) of providing such water, and such invoices shall be paid by Rocky
Mountain in the same manner as is required herein for the payment of Thermal
Payments. Thermo shall not be liable for any damages Rocky Mountain may suffer
because of any unavailability of or interruption or other deficiency in such
utility services including, without limitation water service furnished by
Thermo, unless such interruption or deficiency is caused by the negligent or
intentionally tortious acts or omissions of Thermo, its agents, and employees in
performance of Thermo's obligations hereunder.

                    8.10   Abandonment.  Should Rocky Mountain vacate or abandon
                           ------------                                        
the Facility, Thermo may enter the same, using such force as may be necessary,
change the locks on the doors, and take possession of the Facility, all without
liability to Rocky Mountain. Thereafter Thermo may use the Facility and the Land
for any desired purpose, with or without terminating this in accordance with
provisions of this Agreement concerning Default.

                    8.11   Inspection: Maintenance of Records. Rocky Mountain
                           -----------------------------------
shall permit Thermo to enter and inspect the Facility and the Land at any
reasonable time for any proper purpose, including without limitation review of
compliance by Rocky Mountain with its obligations hereunder and inspection by a
prospective purchaser, mortgagee, or tenant of Thermo's interest in the Facility
or Land. However, Thermo shall have no duty to inspect and no failure by Thermo
to inspect shall relieve Rocky Mountain of any duty which Rocky Mountain may
have under this Agreement. Rocky Mountain shall maintain and preserve, for a
period of at least five (5) years from the close of its applicable fiscal year,
complete books, records, financial statements and tax returns, fully and
accurately reflecting its business activities conducted at and from the Facility
and the financial results of its operation of the Facility. Upon disposal of any
such books, records, financial statements, and tax returns, Rocky Mountain shall
offer to deliver the same to Thermo, which may retain them for Thermo's own
business purposes, subject, however, to the requirements of paragraph 8.12. For
the purpose of ascertaining from time to time that Rocky Mountain is in full
compliance with its obligations hereunder and that any security interest held by
a third party providing debt or equity financing to Thermo for the Plant is not
then, and is not likely to become, impaired, Rocky Mountain shall, from time to
time, within twenty (20) days after receiving a request from Thermo, make
available to Thermo such copies or extracts of, or information from, such books,
records, financial statements, and tax returns, as Thermo or such third party
providing debt or equity financing to Thermo may reasonably request. This
paragraph 8.11 is subject to the provisions of paragraph 8 of the Supplemental
Agreement.

            8.12   Additional information Regarding Operations: Confidentiality.
                   -------------------------------------------------------------
Rocky Mountain acknowledges that Thermo has a vital and protectable interest in
the use and operation of the Facility in full compliance with all terms and
conditions of this Agreement, in receipt of rent and other payments required to
be made by Rocky Mountain hereunder, and in the continuing financial viability
of the Facility as a commercial greenhouse for the entire duration of the
Thermal Term of this Agreement. It is the intention of the parties that in the
event that the leasehold estate for the Facility should expire or be terminated
prior to the end of the Thermal Term, these interests of Thermo shall be
secured, to the maximum extent possible, by the Mortgage. Rocky Mountain
further acknowledges that, in order for such interests to be adequately
protected, it may be necessary for Thermo (or Thermo's designated
representative) to become and remain knowledgeable of the general nature of
Rocky Mountains business activities at the Facility and the activities of
any Greenhouse Affiliates of Rocky Mountain. Therefore, upon request by Thermo,
Rocky Mountain shall, in addition to the information available to Thermo under
paragraph 8.11, also provide to Thermo from time to time after request by Thermo
reasonable access to other sources of information concerning Rocky Mountain's
business and Rocky mountains activities at the Facility, plus complete and
accurate information on gross cash receipts derived from operation by Rocky
Mountain's Greenhouse Affiliates of other commercial Greenhouses. Such
information may include, without limitation, Rocky Mountain's and such
Greenhouse Affiliates' thencurrent business plan and projections of results
of operations. All of such information, plus any information provided to 
Thermo under paragraph 8.11, shall be deemed to be proprietary to Rocky Mountain
and shall be held in confidence by Thermo and any third persons having a need to
know such information because of their interest, financial or otherwise, in
Thermo's business at the Project Site. Such third persons with need to know
shall include, without limitation, those parties from time to time providing
financing for the construction and operation of the Plant and/or the Facility.
Except for disclosure to such third persons with need to know (which shall be
permitted upon such third persons agreeing to be bound by this paragraph) such
information shall not be disclosed by Thermo or by any such third person to
anyone without the prior consent of Rocky Mountain, unless such disclosure is
compelled by applicable law or unless such disclosure is required to protect,
Thermo's, or such third person(s)' legitimate business interests hereunder. Such
legitimate business interests shall include, without limitation obtaining
assurance from time to time that the Plant is and shall remain a Qualifying
Facility. Thermo and such third person(s) shall refrain from any use of such
information which is not reasonably required to protect legitimate interests of
the party obtaining such information during the time while the Thermal Term of
this Agreement remains in effect. Under no circumstances shall any such
information be utilized in any manner to compete with Rocky Mountain or any
Greenhouse Affiliate of Rocky Mountain; provided, however, that this covenant
shall not limit Thermo from exercising any rights or remedies Thermo may have
under this Agreement or under the Mortgage in the event of default by Rocky
Mountain, including without limitation the right to take possession of and
operate the Facility. The additional information to be made available to Thermo
may also include, by way of additional example and without limitation,
invitations for Thermo to attend and observe Rocky Mountain's board meetings and
information concerning and opportunities to observe the day-to-day production,
harvesting, marketing, and shipping activities carried on at the Facility. This
paragraph 8.12 is also subject to the provisions of paragraph 8 of the
Supplemental Agreement.

                    8.13   Duration of Covenants. Thermo and Rocky Mountain 
                           ----------------------
shall be and remain obligated to each other as provided in this section 8 for a
period which commences with the Commencement Date and expires on the expiration
of the Thermal Term. Should Rocky Mountain purchase the Facility (and if
applicable the land), the provisions of this section 8 shall constitute
covenants running with the Land and with the portion of the Project Site
described in Part II of Exhibit A, and be binding on Rocky Mountain and Thermo,
and their respective successors-in-title to the Land and the portion of the
Project Site described in Part II of Exhibit A until expiration of the Thermal
Term.

9.   INSURANCE
     ---------

                    9.1    Required Insurance Coverages: Limits. Subject to 
                           -------------------------------------
paragraph 9.6, below, beginning on the Commencement Date (or such earlier date 
as Rocky Mountain shall be entitled to beneficial use and occupancy of the 
Facility under paragraph 3.2) or as soon thereafter as the specified risks 
shall arise, and continuing until expiration of the Thermal Term, Rocky 
Mountain (or Thermo pursuant to paragraph 9.6) shall continuously maintain in 
force the following insurance coverage:

                        (a)  property damage insurance on an all risk basis
                             including coverage against damage or loss caused 
                             by earth movement (including but not limited to
                             earthquake, landslide, subsidence, and volcanic 
                             eruption) and flood and providing (i) coverage 
                             for the Facility in a minimum aggregate amount
                             equal to the full insurable value of the Facility
                             (ii) coverage for foundations and other property 
                             below the surface of the ground, and (iii) soft 
                             costs defined as attorneys fees, engineering and 
                             other consulting costs, and permit fees that may
                             be incurred due to damage to the premises in a 
                             minimum amount of $500,000. For purposes of this 
                             paragraph 9.1(a), "full insurable value" shall 
                             mean the full replacement value of the Facility, 
                             including any improvements and equipment without 
                             deduction for physical depreciation and/or 
                             obsolescence; all such policies may have deductible
                             of not greater than $550,000; and 
                        (b)  boiler and machinery insurance coverage at the 
                             Facility, written on a comprehensive form basis 
                             for all insurable objects, including but not 
                             limited to pressure vessels, electrical turbines
                             and equipment, motors, air tanks, boilers,


                                     -30-

                        machinery, pressure piping, or any other 
                        similar objects located on or adjacent to
                        the Facility in a minimum aggregate amount
                        equal to the "full insurable value" (as 
                        defined in paragraph 9.1(a), above, of the 
                        Facility, and expediting expenses in the 
                        amount of $100,000 (with losses to be 
                        adjusted on a full replacement value); all 
                        such policies may have deductibles of not 
                        greater than $50,000; and

                   (c)  all risk rental insurance, payable in event
                        of business interruption sufficient to provide
                        for payment of Base Rent and Additional Rent 
                        for 12 months.

At all times while this Agreement is in effect subsequent to Financial Closing
Thermo and Rocky Mountain shall each continuously maintain in force the
following insurance coverage:

                   (d)  commercial general liability insurance on
                        an occurrence basis against claims for personal 
                        injury (including bodily injury and death) and 
                        property damage, with coverage for products
                        completed operations, blanket, contractual, 
                        explosion, collapse and underground coverage, 
                        broad form property damage, and personal injury,
                        with a $1,000,000 minimum limit per occurrence for
                        combined bodily injury and property damage and
                        a $2,000,000 aggregate annual limit;


                   (e)  workers' compensation insurance as required by 
                        state laws, including employer's  liability 
                        insurance for all employees in the amount of not
                        less than the minimum statutory requirements; and
                   (f)  automobile liability with limits of Two Million 
                        Dollars ($2,000,000) per occurrence with no aggregate
                        limitation.
              
Prior to the time that Rocky Mountain is required to assume responsibility for
insurance coverage, Thermo shall maintain adequate insurance coverage with
respect to such of the foregoing risks as shall then be applicable, including
builder's risk coverage with delay in start up coverage endorsement during
construction.

                                      -31-
<PAGE>
 
          9.2 Certain Policy Requirements. All insurance policies required under
              ---------------------------
paragraph 9.1 shall be written by responsible and accredited companies of
recognized standing authorized to do business in the State of Colorado, with a
Best's Key Rating Guide rating of "A-X" or better (except for Lloyds of London,
AEGIS, Colorado Compensation Insurance Authority or other companies acceptable
to Thermo), and shall provide that the policies shall not be cancelable except
upon sixty (60) days' prior written notice by the insurer to the party to this
Agreement which is not the owner of the policy, and to any mortgagee of the
Facility. Property insurance policies carried by Thermo shall include a
lender's loss payable endorsement similar to form 438 BFU. All liability
policies shall be endorsed (i) to provide a severability of interests or cross
liability clause; and (ii) that the insurance shall be primary and not excess to
or contribution with any insurance or self-insurance maintained by others. Rocky
Mountain's policies shall be endorsed to name Thermo, any mortgagee of the
Facility, their respective officers, agents, partners, and such other parties as
may reasonably be requested by Thermo as additional insured parties, as their
interests may appear. Thermo's policies shall be endorsed to name Rocky
Mountain, its managers, agents, and such other parties as may reasonably be
requested by Rocky Mountain as additional insured parties, as their interests
may appear. Each party shall deliver to the other a copy of such policies (or,
in lieu of policies of insurance, certificates of insurance if then acceptable
to such recipient) prior to the Commencement Date, and a copy of any renewal
policy or certificate of insurance if then acceptable to Thermo shall be
delivered to Thermo and to any mortgagee of the Facility at least fifteen (15)
days prior to the termination date or any expiring policy. Thermo's liability
insurance policy shall provide that in the event of injury as a result of the
sole negligence of Thermo, to persons or property on the Land, Thermo's
liability coverage shall be primary, and in the event of injury to such persons
as a result of the joint or concurrent negligence of Rocky Mountain and Thermo,
the liability coverage of Thermo and Rocky Mountain shall contribute in
proportion to the negligence of the insured parties. Rocky Mountain's liability
insurance policy shall provide that in the event of injury, as a result of the
sole negligence of Rocky Mountain to persons or property on the cogeneration
Plant site, Rocky Mountain's liability coverage shall be primary and in the
event of injury to such persons as a result of the joint or concurrent
negligence of Thermo and Rocky Mountain the liability insurance coverage of
Rocky Mountain and Thermo shall contribute in proportion to the negligence of
the insured parties.

          9.3 Application of Proceeds. Anything herein to the contrary
              -----------------------
notwithstanding, Thermo and Rocky Mountain agree that at all times while the
Lease Term remains in effect the proceeds of any policy of fire and extended
coverage insuring against casualty loss to the Facility shall be disbursed and
applied in accordance with the requirements of any loan agreement and supporting
security documents in effect between Thermo and any secured lender providing
financing for the Plant and/or the Facility. Both parties shall upon request
promptly take such steps as may be required to cause the disbursement and
application of proceeds provisions of such policies to conform to the secured
lender's requirements. Subsequent to purchase by Rocky Mountain of the Facility
(and the Land, if applicable), Rocky Mountain shall cause each and every
mortgagee of the Facility to agree to disburse, in accordance with such
mortgagee's standard construction loan practices, amounts received by such
mortgagee from fire and extended coverage insurance policies for use by Rocky
Mountain in repairing, rebuilding, or reconstructing the Facility in accordance
with the obligations of Rocky Mountain hereunder. This paragraph 9.3 is subject
to the requirements of paragraph 10 of the Supplemental Agreement.

<PAGE>
 
          9.4 Waiver of Subrogation. Thermo and Rocky Mountain each hereby
              ---------------------                           
waive on behalf of themselves and on behalf of all carriers of the insurance
required to be maintained pursuant to paragraph 9.1 above, all claims, by
subrogation or otherwise, which such waiving party might otherwise have against
the other for loss or damage to the Facility and the Land and the respective
interests of both such parties therein, and for legal liability arising out of
perils insured against in accordance with such requirements of this Agreement,
but only if this waiver does not or will not invalidate, limit, or otherwise
restrict coverage.

          9.5 Exculpation for Property Damage. Subject to paragraphs 7.3 and 9.7
              -------------------------------
hereof, all personal property of every kind and description, including without
limitation growing crops and agricultural products, that may at any time be in,
at or on the Facility or the Land shall be kept in, at or on the Facility or the
Land at Rocky Mountain's sole risk, or at the risk of those claiming under Rocky
Mountain. Without limitation of the foregoing waivers of claims and subrogation,
Thermo shall not be liable for any damage to said personal property or any loss
of business by Rocky Mountain however arising, including without limitation from
the bursting, overflowing, or leaking or water or pipes, from the malfunction of
the heat transfer subsystem, or from other heating, electrical, or plumbing
fixtures, from electric wires, from gas or odors, from acts of other persons on
or in the vicinity of the Project Site or from any other cause in any other
manner whatsoever, except to the extent that such damage to personal property
may result from and actually be caused by the negligent or willfully tortious
acts or omissions of Thermo provided, however, that the general limitations of
this paragraph 9.5 shall be subject to the specific limitations of paragraphs
7.4 and 9.7 with respect to any failure by Thermo to provide thermal energy to
Rocky Mountain as required hereunder. Rocky Mountain shall be responsible for
disclosing the contents of this paragraph 9.5 to any insurer of Rocky Mountain's
business activities and for taking such steps, if any, as such insurer may
require to maintain coverage of Rocky Mountain's personal property.

          9.6 Property, Insurance During Lease Term. Anything in this section 9
              -------------------------------------
to the contrary notwithstanding, while this Agreement (including both the Lease
Term and the Thermal Term) remains in effect Thermo may insure the Leased
Premises against fire and extended coverage perils, and such other casualty
losses as may be required under clauses (a), (b) and (c) of paragraph 9.1,
either separately or in conjunction with similar insurance which may be carried
by Thermo on the Plant, and Thermo shall do so if the result of insuring the
Facility in this manner would be to reduce the combined cost of separate
insurance premiums for separate property insurance meeting such requirements on
the Plant and the Facility. If the Leased Premises are insured in this manner,
Rocky Mountain shall not be obligated to carry the insurance required, by
clauses (a), (b) and (c) of paragraph 9.1, but in lieu thereof shall pay to
Thermo as Additional Rent (or as a reimbursement of Thermo's incremental costs
therefor if the Lease Term shall no longer be in effect) an equitably allocated
share of the premium from time to time paid by Thermo for such insurance based
on the relative replacement costs of the Plant and the Facility. Such insurance
carried by Thermo on the Plant and the Facility shall name Thermo and Rocky
Mountain as insureds, as their interests may appear. In the event that such
combined insurance is maintained in force, if the cause of loss can be
determined to have originated in the negligence of either Thermo or Rocky
Mountain, the party responsible for such loss shall be responsible for payment
of any deductible amount; otherwise, the impact of the deductible shall be borne
by the parties equally.

          9.7 Certain Special Loss Coverages. Beginning on the Commencement Date
              ------------------------------                              
or as soon thereafter as the risk shall arise, and continuing until such time as
the Facility shall include permanent standby heat generating or emergency heat
storage equipment, insurance shall also be maintained against losses, including
loss of revenue and reasonably estimated profits, which would be incurred by
Rocky Mountain for damage to crop (including without limitation substantial or
total loss of crop) resulting from failure by Thermo to furnish thermal energy
as required by paragraphs 7.1, 7.3 and 7.4. Rocky Mountain and Thermo shall
consult from time to time with each other and with insurance consultants
concerning the required limits of such policy(ies) and most effective and least
expensive manner of obtaining such coverage, the parties agreeing that it is in
their mutual best interests to maintain flexibility with respect to the specific
type of coverage or coverages which shall be obtained and the party or parties
which shall be designated as named insured thereunder. After such consultation,
the form of coverage shall be selected by Thermo in good faith and with due
consideration of the objectives described above. Thermo shall pay the premium
for such insurance, or, if coverage is effected by endorsement to insurance
coverage otherwise required to be maintained by Rocky Mountain hereunder, shall
reimburse Rocky Mountain for incremental premium costs due to such insurance.
Should insurance then be required under this paragraph 9.7, and should Thermo
fail or decline to select such coverage or to pay the premium (or reimburse
Rocky Mountain for the incremental premium) therefor, Rocky Mountain may effect
such insurance, not less than three (3) days prior notice to Thermo and in such
event Thermo shall reimburse Rocky Mountain for the premiums attributable
thereto; provided, however, that such reimbursement shall not exceed one hundred
twenty percent (120%) of the most recent premium (or reimbursement) incurred by
Thermo for such insurance. Thermo shall have the right to reinstate coverage
upon expiration of any policy thus procured by Rocky Mountain. If the policy or
policies selected to provide this coverage shall be issued for the direct
benefit of Rocky Mountain, such policies shall be primary and noncontributory
with other policies. Without limitation of the foregoing general requirements
and solely for the purposes of illustration, among the forms of coverage, which
may be selected, separately or in combination, are:

          (a)  "failure to supply coverage," to be maintained by Thermo in
               addition to Thermo's general liability coverage (generally to
               be considered only if other coverage is unavailable or not
               satisfactory to provide adequate recover to Rocky Mountain);

          (b)  "extended crop insurance coverage-temperature variation," to
               be maintained by Rocky Mountain in addition to Rocky Mountain's
               standard named peril or broad form crop insurance;

          (c)  "contingent business interruption coverage," to be maintained by
               Rocky Mountain on a scheduled monthly limit basis; and

          (d)  "business interruption coverage for loss from a named peril"
               (failure to supply heat), to be maintained by Thermo as insured
               with an

                                     -34-
<PAGE>
 
               extension corresponding to extended crop insurance to provide
               payments equivalent to extended crop coverage to Rocky Mountain
               as its interests may appear.

If the policy of insurance required by this paragraph 9.7 names Rocky Mountain
as an insured, such policy shall be endorsed with a broad form waiver of
subrogation reasonably satisfactory to Thermo and any party providing secured
financing to Thermo for construction and operation of the Plant and/or the
Facility. The waiver of subrogation in this paragraph 9.7 shall not be construed
to limit any other waiver of claims and subrogation or limitation of Thermo's
liability, provided under other paragraphs of this Agreement, including without
limitation paragraph 7.4. All proceeds of such insurance received by Rocky
Mountain, including without limitation proceeds received indirectly through
Thermo pursuant to Thermo's obligations under paragraph 7.4 or otherwise, shall,
to the extent such proceeds represent compensation for expenditures which are
(or if incurred would have been) deductible for the purpose's of determination
of Available Net Cash, or to the extent such proceeds represent revenues not
received because of such loss of crop, be deemed to be Available Net Cash
without regard to the apportionment requirements set forth in paragraph 4.5,
above.

     10.  GENERAL INDEMNIFICATION
          -----------------------

          10.1 By Rocky Mountain. Subject to such waivers and limitations of
               -----------------                                          
liability as are specifically provided hereunder, Rocky Mountain shall at all
times defend, indemnify and save Thermo, Thermo's Partners, and their respective
shareholders, directors, officers, agents and employees and any lender providing
secured financing to Thermo and such lender's shareholders directors, officers,
agents and employees (collectively "Indemnitees") harmless from any and all
Damages relating to the Facility and the Land, and from any Damages that may
occur or be claimed by or with respect to any party, person or persons, entity,
property or chattels in, on, or about the Facility or on the Land, resulting in
whole or in part from any negligent or willfully tortious act done or omission
by or through Rocky Mountain, any Affiliate of Rocky Mountain, or any party in
the Facility or on the Land or resulting from Rocky Mountain's, any such
Affiliate's or any such third party's use, non-use, or occupancy of the Facility
in any manner contrary to the requirements of this Agreement. Without limiting
the generality of the foregoing, Rocky Mountain shall defend, indemnify and save
such Indemnitees harmless from any and all Damages that may occur or be claimed
with respect to Rocky Mountain's, any Affiliate of Rocky Mountain's or any such
third party's violation or failure to comply with all Environmental Laws. This
paragraph 10.1 is subject to the provisions of paragraph 6.2 of the Supplemental
Agreement. This covenant of indemnity shall survive expiration or termination of
this Agreement, and shall be construed as supplementary to and not be construed
to conflict with or limit any other covenant of indemnity contained in this
Agreement.

          10.2 By Thermo. Subject to such waivers and limitations of liability
               ---------
as are specifically provided hereunder, Thermo shall at all times defend,
indemnify and save Rocky Mountain and Rocky Mountain's members and their
respective shareholders, directors, officers, agents and employees (collectively
"Indemnified Persons") harmless from any and all Damages relating to the Plant,
and from any Damages that may occur

                                      -35-
<PAGE>
 
or be claimed by or with respect to any party, person or persons, entity,
property or chattels in, on, or about the Plant or the Project site (exclusive
of the Land), resulting in whole or in part from any negligent or willfully
tortious act done or omission by or through Thermo, any Affiliate of Thermo, or
any third party in the Plant or on the Project Site exclusive of the Land, or
resulting from Thermo's, any such Affiliate's or any such third party's use, 
non-use or occupancy of the Plant in any manner contrary to the requirements of
this Agreement. Without limiting the generality of the foregoing Thermo shall,
except to the extent of such waivers and limitations, defend, indemnify and save
such Indemnified Parties harmless from any and all Damages that may occur or be
claimed with respect to Thermo's, any Affiliate of Thermo's or any such third
party's violation of or failure to comply with all Environmental Laws. This
covenant of indemnity shall survive expiration or termination of this Agreement,
and shall be construed as supplementary to and not be construed to conflict with
or limit any other covenant of indemnity contained in this Agreement.

     11.  DAMAGE OR DESTRUCTION
          ---------------------

          11.1 Rebuilding Required.  If, at any time during the Thermal Term of
               -------------------
this Agreement (and whether or not Rocky Mountain is then a lessee under this
Agreement), the Facility is damaged or destroyed by fire, hail, windstorm, or
other casualty, regardless of the severity of such loss and whether or not such
loss shall have been insured against, Rocky Mountain shall, unless Thermo shall
consent to Rocky Mountain not rebuilding, promptly repair, and reconstruct the
Facility. If Rocky Mountain is a lessee of the Facility at the time such damage
or destruction occurs, the Facility shall Ve repaired and reconstructed to
substantially the same condition, or better, as existed immediately prior to
such casualty loss. If Rocky Mountain has purchased the Facility, prior to the
time such damage or destruction occurs, the Facility shall be repaired and
reconstructed in such manner as Rocky Mountain may determine in Rocky Mountain's
discretion, reasonably exercised; provided, however, that: (a) such repair and
reconstruction is completed within 180 days or less after the date of such
damage or destruction; (b) after such repair and reconstruction, Rocky
Mountain's annual requirements for thermal energy supplied by the Plant and used
for commercial or industrial purposes shall not be less than the Minimum Annual
Heat Requirement; and (c) the use of such thermal energy shall qualify the Plant
as a Qualifying Facility. All repair and reconstruction of the Facility/Plant
interface equipment shall be subject to Thermo's prior approval, which shall not
be withheld or delayed unreasonably. Any repair or reconstruction of the
Facility for a purpose other than a commercial greenhouse shall require Thermo's
prior consent, which may be withheld. For the purpose of repair and
reconstruction, Thermo shall waive Thermo's interest in insurance proceeds, if
any, relating to such casualty loss, but Rocky Mountain's obligation to repair
and reconstruct shall be limited by the amount of insurance proceeds. Thermo may
provide for the payment of such insurance proceeds in a manner which assures
Thermo of satisfactory, lien-free completion of such repair or reconstruction.

          11.2 No Abatement of Rent. If Rocky Mountain is a lessee hereunder at
               --------------------
the time of such casualty loss, neither Base Rent nor Additional Rent shall be
abated or reduced during any period in which the Facility is being repaired or
reconstructed or is otherwise untenantable, it being the intention of the
parties that business interruption insurance shall be maintained hereunder.

          11.3 Impact of Certain Thermo Financing. The provisions of this
               ----------------------------------
section 11 are subject to the provisions of paragraph 10 of the Supplemental
Agreement.

     12.  EMINENT DOMAIN.
          --------------

          12.1 Condemnation During Leasehold - Substantial. If, during any
               -------------------------------------------
period in which Rocky Mountain is a lessee under this Agreement, the Leased
Premises or any part thereof is condemned or appropriated by any public
authority, all proceeds of such taking shall belong and are hereby assigned to
Thermo, but shall be subject to distribution as herein provided. If any such
taking would materially and adversely affect the ability of Rocky Mountain to
meet its obligations under section 7 notwithstanding any practical repair or
restoration of the Leased Premises, this Agreement (including without limitation
the thermal supply provisions hereof) shall terminate, and if the Purchase
Option shall not have lapsed, Rocky Mountain shall be deemed to have exercised
the Purchase Option as of the effective date of the appropriation, subject,
however, to the provisions of paragraph 4 of the Supplemental Agreement. In such
event, the proceeds of such appropriation shall be applied: first, to pay to
Thermo an amount equal to the amount which is due to Thermo upon purchase
pursuant to exercise of the Purchase Option, second, to compensate Thermo for
the value of any Land and appurtenant rights easements taken but not compensated
in accordance with the Purchase Option formula, third, to compensate Thermo for
the reasonable costs anticipated by Thermo to be incurred in obtaining at the
Project Site a replacement user of thermal energy so that the Plant shall at all
times remain a Qualifying Facility, and fourth, the balance of such condemnation
proceeds, if any, shall belong to Rocky Mountain. If the Purchase Option shall
have lapsed, this Agreement, including both Rocky Mountain's leasehold estate
and the thermal supply provisions hereunder. shall terminate, and the entire
proceeds of condemnation shall be retained by Thermo.

          12.2 Condemnation During Leasehold - Nonsubstantial. If a portion of
               ----------------------------------------------
the Facility and/or the Land is condemned or appropriated by any public
authority during the term of Rocky Mountain's leasehold interest in a manner
which would not materially and adversely affect the ability of Rocky Mountain to
meet its obligations under section 7 after practical repair and reconstruction,
this Agreement shall remain in effect and Rocky Mountain shall repair and
reconstruct the Facility to as nearly as practicable the same condition, or
better, as existed immediately prior to such taking, in which event Thermo shall
deliver the proceeds relating to such condemnation or appropriation loss to
Rocky Mountain less an equitable amount retained by Thermo to compensate Thermo
for any portion of the Land and any appurtenant rights and casements taken.
Rocky Mountain's obligation to repair and reconstruct shall not be limited to
the proceeds of condemnation available for such purposes. Thermo may provide for
the payment of such proceeds in a manner which assures Thermo of satisfactory,
lien-free completion of such repair or construction.

          12.3 Condemnation After Purchase of Leased Premises. If the Facility
               ----------------------------------------------
and/or the Land, or any part thereof is condemned or appropriated by any public
authority during any period after which Rocky Mountain has purchased the
Facility (and, if applicable, the Land), the proceeds of condemnation shall
belong to, and be apportioned between, the parties as follows: Rocky Mountain
shall retain all proceeds of condemnation which are reasonably apportionable to
the interest then owned by Rocky


                                      -37-
<PAGE>
 
Mountain in that portion of the Land and/or the Facility which is taken, and
Thermo shall retain all proceeds of condemnation payable which are reasonably
apportionable to any interests then owned by Thermo in such property and any
easements and appurtenant rights of Thermo taken or already affected. The
foregoing notwithstanding, each party shall, if commercially practical (in
Thermo's discretion, reasonably exercised), repair and reconstruct their
respective interests in the Facility and the Plant so that section 7 and all
related provisions of this Agreement shall remain in effect until expiration of
the Thermal Term. Such obligation to repair and reconstruct shall not be limited
by the proceeds of condemnation available for such purposes. If such repair or
restoration is not commercially practical under those circumstances, this
Agreement shall thereupon terminate. In the event of such termination, any
remaining proceeds of condemnation shall be applied first to reimburse Rocky
Mountain for the Option Purchase Price paid by Rocky Mountain, next as provided
in clause "third" and finally as provided in clause "fourth" under paragraph
12.1.

          12.4 Special Provisions Concerning Condemnation. Ground rent, if being
               ------------------------------------------
paid with respect to Land only at the time of any condemnation, shall, if this
Agreement does not terminate, abate in proportion to the ratio of the area of
the Land taken to the area of the Land prior to the appropriation. Thermal
Payments shall abate during repair and reconstruction only to the extent that
Rocky Mountain's ability to utilize thermal energy is reduced. Rocky Mountain
shall not transfer or convey its interest in the Facility or the Land, or any
part thereof under threat of condemnation, nor shall Rocky Mountain settle any
proceedings or suit in eminent domain affecting the Facility or the Land (or any
interest of Rocky Mountain therein), without the prior consent of Thermo.
Regardless of whether Rocky Mountain shall have purchased the entire Leased
Premises prior to such condemnation, Rocky Mountain irrevocably consents to the
appearance by Thermo, in any such eminent domain proceedings or suit, for the
purpose of proving or to prove such damages to Thermo's compensable property
rights and economic interests as may appear because of such eminent domain
proceedings or suit.

          12.5 Impact of Certain Thermo Financing. The provisions of this
               ----------------------------------
section 12 are subject to the provisions of paragraph 10 of the Supplemental
Agreement.

     13.  DEFAULT AND REMEDIES
          --------------------

          13.1 Default Defined: Cure Period. Should Rocky Mountain fail to pay
               ----------------------------
any installment of Base Rent, Additional Rent, or any other sum herein required
to be paid to Thermo (including without limitation Thermal Payments) within
thirty (30) days after such payment is due and payable, making due allowance, if
applicable, for any Postponement to which Rocky Mountain may be entitled
hereunder, and Thermo shall have made written demand therefor; or should Rocky
Mountain abandon, vacate, or fail to operate the Facility as required hereunder;
or should Rocky Mountain fail to maintain any required insurance; or should
Rocky Mountain fail to perform any other covenant or to comply with any other
condition herein provided to be performed or complied with by Rocky Mountain
(other than the payment of money, continuation of operations, and maintenance of
insurance) within thirty (30) days after receipt by Rocky Mountain of written
notice thereof from Thermo (or, in the event such failure can be removed or
corrected, but cannot be removed or corrected within such thirty (30) day
period, in the


                                      -38-
<PAGE>
 
event Rocky Mountain does not commence to remove or correct such failure as
quickly as practical within said thirty (30) day period and thereafter
diligently pursue such removal or correction to completion as quickly as may be
reasonably practicable but in any event within one hundred eighty (180) days
after the onset of such failure); or should any proceeding in bankruptcy or
under any state or federal law relating to the relief of debtors be filed by or
against Rocky Mountain; or should a receiver be appointed of any of the property
of Rocky Mountain so as to directly affect the fulfillment of the obligations of
Rocky Mountain hereunder then and in any such event Rocky Mountain shall be in
"Default" hereunder.

          13.2 Right to Terminate: Re-entry. At any time while Rocky Mountain is
               ----------------------------
in Default, Thermo may: (a) unless Rocky Mountain shall have previously
purchased the Facility, terminate without Notice Rocky Mountain's right to
possession of the Facility without terminating this Agreement, and thereupon
Thermo may enter and retake possession of the Facility without Notice or demand
and may, without being required to, sublease the Facility as agent of Rocky
Mountain on such sublease terms and conditions as Thermo in its discretion may
deem obtainable for the balance of the Lease Term (subject to the thermal supply
provisions of this Agreement), and receive the sublease rent therefor, applying
the same first to the payment of expenses of such re-entering and subletting and
then to the payment of all rent and other charges due or to become due to Thermo
under the terms of this Agreement, and Rocky Mountain shall pay any deficiency,
or (b) whether or not Rocky Mountain shall have purchased the Facility, declare
this Agreement terminated without Notice. If Thermo retakes possession of the
Facility, Thermo may use such force as Thermo, in Thermo's discretion, may
believe to be necessary to do so without the benefit of prior judicial process
and without being deemed to have committed a breach of peace.

          13.3 Retention and Acceleration of Rent. If Thermo terminates this
               ----------------------------------
Agreement because of a Default by Rocky Mountain while Rocky Mountain remains a
lessee of the Facility, Thermo shall be entitled to retain any and all sums paid
by Rocky Mountain hereunder to the date of termination without prejudice to
recovery of additional damages arising from such Default, and, at the option of
Thermo exercised without Notice to Rocky Mountain, the Base Rent for the entire
remaining Lease Term of this Agreement, discounted to the then present value of
such total remaining sum at the actual average rate of interest determined under
paragraph 4 of the Memorandum Regarding Adjustment of Rent and Option Price,
plus any then-existing Postponements of Base Rent shall accelerate and shall
become immediately due and payable. In case Rocky Mountain is declared bankrupt
or voluntarily offers to creditors terms of composition, or in case a receiver
is appointed to take charge of and conduct the affairs of Rocky Mountain, or if
an order for relief is granted for or against Rocky Mountain, such claim for
unpaid and accelerated installments of Base Rent due under this Agreement shall
constitute a debt provable in bankruptcy or receivership.

          13.4 Other Available Remedies. If Rocky Mountain should commit a
               ------------------------
Default under this Agreement (regardless of whether Rocky Mountain has purchased
the Facility), Thermo shall also be entitled to such other remedies as it may
have at law or in equity on account of such Default, including without
limitation the right to obtain equitable relief such as injunction or a decree
of specific performance, and to proceed against property mortgaged under the
terms of the Mortgage (if any) then granted pursuant to paragraph 5.8. The
remedies to which Thermo may resort under this


                                      -39-
<PAGE>
 
Agreement are cumulative and are not intended to be exclusive of, and Thermo
shall be entitled to exercise, any other remedy to which Thermo may be entitled 
by law or in equity.

          13.5 Payment of Enforcement Expenses. To the maximum extent permitted
               -------------------------------
by law, should either party commit a Default under this Agreement, the
defaulting party covenants and agrees to pay and discharge all reasonable costs
and expenses which shall be incurred by the non-defaulting party arising out of
such Default, in enforcing the covenants and agreements of this Agreement,
including without limitation reasonable attorneys' fees.

          13.6 Forbearance not to Limit Remedies. The failure of Thermo to
               ---------------------------------
insist in any one or more cases on strict or specific performance of any
provision of this Agreement or to exercise any right herein contained shall not
constitute a waiver in the future of such right. Acceptance by Thermo of rent or
other payment, or acceptance of any other performance required hereunder with
knowledge of a breach, by Rocky Mountain of any provision hereof shall not
constitute a waiver of such breach nor shall any acceptance of rent or other
payment in a lesser amount than herein provided for operate or be construed in
any other manner other than as a payment on account of the earliest rent or
other charge then unpaid by Rocky Mountain.


     14.  ASSIGNMENT, SUBLEASING.
          AND SUBCONTRACTING
          --------------------

          14.1 Assignment by Rocky Mountain. Rocky Mountain may not assign its
               ----------------------------
rights, or any of them hereunder except to an Affiliate of Rocky Mountain which
shall assume in writing and agree to be bound by all of the terms, conditions,
duties and obligations hereunder and then only if Thermo shall have given its
prior consent to such assignment. Thermo shall not withhold or delay such
consent unreasonably. Rocky Mountain shall not make or agree to make any partial
assignment of the rights granted or conferred hereunder. Except by Thermo acting
on behalf of Rocky Mountain pursuant to paragraph 13.2, no sublease of the Lased
Premises or any portion thereof, or any subcontract for sale of thermal energy,
water, or otherwise, shall be granted hereunder. Any assignment, sublease, or
subcontract (or attempted assignment, sublease, or subcontract) in violation of
these restrictions shall be void. This paragraph 14.1 is subject to the
provisions of paragraph 5.6 of the Supplemental Agreement.

          14.2 Effect of Assignment. In the event that Rocky Mountain assigns
               --------------------
its rights or any of them hereunder to Rocky Mountain's Affiliate, such
assignment shall not relieve Rocky Mountain of any obligations hereunder. Any
event subsequent to such assignment that causes Rocky Mountain to no longer have
a substantial economic investment in or economically significant relationship
with the entity or person that is Rocky Mountain's Affiliate shall be deemed an
assignment of this Agreement and shall not be valid unless Thermo's prior
consent shall have been obtained.

          14.3 Assignment by Thermo. Thermo may assign its rights hereunder, or
               --------------------
any of them, collaterally for financing purposes or otherwise, without
limitation.

                                      -40-
<PAGE>
 
          14.4 Bind and Inure. All terms, conditions, duties, and obligations of
               --------------
this Agreement shall be binding on, and all rights and benefits shall inure to
the benefit of, the respective permitted successors and assigns of Thermo and
Rocky Mountain.

          14.5 Third-Party Rights. Whenever this Agreement or the Supplemental
               ------------------
Agreement expressly provides for rights of review, consent, approval, or similar
rights to be exercised by third parties providing financing for the Plant and/or
the Facility such rights may be assigned to any assignee of such third party's
rights under any secured financing loan agreement with Thermo, or any security
documents supporting such loan agreement, and such rights of review, consent,
and approval shall be deemed to have been assigned by any such third party to
the assignee of any such third party's rights under such secured loan agreement.
Except as expressly provided in paragraph 8.12 relating to confidentiality of
Rocky Mountain's proprietary information, under no circumstances shall the
conferring of such third-party rights under this Agreement impose any duties on
such third parties, their successors and assigns.

     15.  SURRENDER: PERSONAL PROPERTY
          ----------------------------

          15.1 Condition upon Termination. Except to the extent that Rocky
               --------------------------
Mountain shall have purchased the Leased Premises. Rocky Mountain shall
surrender the Leased Premises to Thermo upon expiration or termination of the
Lease Term in as good condition and repair as the same shall be at the
commencement of the Lease Term, ordinary wear and tear and erection of permitted
improvements thereon, excepted. No tenancy of any duration (other than a tenancy
at will), nor any extension of the thermal supply covenants of this Agreement,
shall be created by Rocky Mountain's holding over beyond the end of the Lease
Term.

          15.2 Responsibility for Personalty. All equipment and trade fixtures
               -----------------------------
furnished by Rocky Mountain and used in the operation of the Facility, including
without limitation any tanks, pipes, and connections installed by Rocky Mountain
on the Leased Premises (unless such equipment and fixtures are included in the
Work under the Construction Contract), shall at all times be and remain the
personal property of Rocky Mountain. Unless Rocky Mountain shall have purchased
both the Facility and the Land, Rocky Mountain shall, on or prior to the date of
expiration or termination of the Lease Term, remove all of such equipment and
trade fixtures from the Leased Premises; provided, however, that upon request
made by Rocky Mountain not less than one hundred eighty (130) days prior to
expiration or termination. Thermo shall permit Rocky Mountain to remain in
possession as a holdover tenant for up to ninety (90) days, during which time
such equipment and fixtures may be removed. Rocky Mountain shall pay a
reasonable holdover rent specified by Thermo at such time during the holdover
period. At Thermo's request, Rocky Mountain shall repair all damages to the
Facility and the Land caused by such trade fixtures and equipment or by their
removal.

          15.3 Removal of Facility. If Rocky Mountain shall have purchased the
               -------------------
Facility but not the Land, then upon expiration or termination of the Lease
Term, the Facility may, at Rocky Mountain's option, be removed from the Land in
the same manner as provide in paragraph 15.2 for removal from the Facility of
trade fixtures and equipment. Unless Rocky Mountain shall have purchased the
Land as herein provided,


                                     -41-
<PAGE>
 
any property of any nature whatsoever of Rocky Mountain which is not removed on
or before the latest date provided for removal under this section 15 shall
conclusively be deemed to have been abandoned by Rocky Mountain and all right,
title, and interest of Rocky Mountain in such property shall thereby pass
irrevocably to Thermo, which may then use or dispose of such property as Thermo
sees fit. In the event the Facility is so removed by Rocky Mountain, Rocky
Mountain shall prepare the Land, as reasonably required by Thermo, for
commercial or industrial redevelopment.

     16.  SUBORDINATION
          -------------

          16.1 Subordination: Nondisturbance. This Agreement and all rights of
               -----------------------------
Rocky Mountain hereunder, including without limitation the Purchase Option
granted under section 5, shall be subordinate to the lien of each and every
mortgage, deed of trust, or other financing encumbrance of any nature which
Thermo may grant affecting the Project Site or any portion thereof (including 
without limitation the Land), whether previously or hereafter made, unless the
holder of any such financing encumbrance elects by recorded instrument that this
Agreement shall be prior to such encumbrance. This subordination shall be self-
executing and effective without any further action by any party; provided,
however, that Rocky Mountain shall not be required to subordinate its rights and
interests under this Agreement to the lien of any such financing encumbrance
hereafter made unless the holder thereof shall execute a subordination,
attornment and nondisturbance agreement which shall provide in substance: (a)
that this Agreement shall not be terminated by such holder so long as Rocky
Mountain is not in Default of its obligations hereunder; (b) that such holder
shall recognize Rocky Mountain's Purchase Option if the same shall be exercised,
and upon payment to the holder of the net proceeds of such purchase such holder
shall release the lien on the Facility and, if applicable, the Land (subject,
however, to the limitations of paragraph 4 of the Supplemental Agreement); and
(c) that in the event of foreclosure or other action by such holder to enforce
its rights under such financing encumbrance (should Thermo have defaulted in its
obligations to such holder). Rocky Mountain shall remain bound to and shall
recognize such holder, and the successors or assigns of such holder, to the same
extent that Rocky Mountain shall then be required to recognize and be bound to
Thermo hereunder.

          16.2 Estoppel Certificates. Rocky Mountain agrees, from time to time,
               ---------------------
immediately upon request by Thermo, promptly to execute such instruments,
certificates, and tenant estoppel letters as may be reasonably requested by
Thermo to evidence and confirm the subordination herein provided and the then-
current status of this Agreement, stating fully and accurately whether either
party is in default hereunder and whether this Agreement has been amended,
modified or waived in any respect (together with full particulars of such
defaults, amendments, modifications, and waivers), plus such other relevant
factual information with respect to this Agreement as Thermo may reasonably
request. Rocky Mountain shall promptly deliver such instruments, certificates
and letters to any third party designated by Thermo as having a bona fide reason
to know such information, and in the default of such delivery hereby irrevocably
designates Thermo as Rocky Mountain's attorney-in-fact to execute and deliver
such instruments, certificates and letters on Rocky Mountain's behalf.


                                      -42-
<PAGE>
 
     17.  QUIET ENJOYMENT
          ---------------

     Thermo covenants that, for so long as Rocky Mountain shall enjoy any
leasehold estate under this Agreement, Rocky Mountain, having performed all
covenants and obligations herein set forth, shall have quiet and peaceable
possession of the Leased Premises, subject to and on the terms and conditions
herein provided (including, without limitation, subordination pursuant to
paragraph 16.1), free and clear of any claim by, from, through, or under any
person lawfully claiming an interest in the Leased Premises from or through
Thermo.

     18.  INDEPENDENT CONTRACTORS
          -----------------------

     Nothing herein shall be deemed to constitute Thermo and Rocky Mountain as
partners or joint venturers of any nature or to provide that either party shall
have any responsibility or authority for or in connection with the business
activities of the other. Neither party shall have any control over or
responsibility for or obligations to the employees or agents of the other. The
relationship of the parties hereunder is that of independent contractors and,
except to the extent that Rocky Mountain shall have exercised the Purchase
Option, of lessor and lessee.

     19.  REFORMATION: SEVERABILITY
          -------------------------

     If any clause or provision of this Agreement shall be held by final
judgment of a court of competent jurisdiction to be illegal, invalid, or
unenforceable, then it is the intention of the parties that the remainder of
this Agreement shall not be affected thereby, and in lieu of each clause or
provision of this Agreement that is illegal, invalid, or unenforceable, there
shall be added as a part of this Agreement a clause or provision as similar
in terms to such illegal, invalid, or unenforceable clause or provision as may
be possible without being illegal, invalid, or unenforceable. If such
reformation cannot be accomplished, the offending provision shall be stricken
and the remainder of this Agreement shall remain in full force and effect;
provided, however, that if such offending provision cannot be reformed without
resulting in a material change in the contractual relationship between the
parties, thereby depriving either or both of the parties of the benefit of the
fundamental economic bargain herein provided, this Agreement shall become
voidable upon demand of the party whose economic interests are thus impaired.

provide verification thereof, or, if facsimile or electronic mail Notices have
been requested by such recipient by Notice as herein provided, at the option of
the sender by facsimile or electronic mail transmission initiated and completed
during the ordinary business hours of the intended recipient; provided, however,
that no Notice given by facsimile or electronic mail shall be deemed given

section 20 is subject to the provisions of paragraphs 9 and 14 of the
Supplemental Agreement.

     21.  FINANCING BY THERMO
          -------------------

          21.1 Condition Subsequent. All obligations of Thermo and Rocky
               --------------------
Mountain hereunder are conditioned on Thermo, on or before April 30, 1993,
having closed and become entitled to draw funds under a financing arrangement
sufficient to construct and start up the Plant and to pay the Contract Sum under
the Construction Contract ("Financial Closing"). Thermo shall advise Rocky
Mountain from time to time upon Rocky Mountain's request concerning Thermo's
progress toward Financial Closing. If Financial Closing does not occur on or
before such date, this Agreement shall be deemed canceled without any further
obligation of either party to the other; provided, however, that at the option
of either party, exercised by Notice to the other on or before such date, this
time for automatic cancellation shall be extended as set forth in the Notice of
extension, but to no later than February 1, 1994. Should the condition
subsequent provided in this paragraph be fulfilled within the time so provided
by the execution between Thermo and Prudential of the "Loan Agreement," the
Supplemental Agreement shall remain in effect. Should this condition
subsequently be fulfilled in any other manner, the Supplemental Agreement shall
become null and void and of no further force and effect.

          21.2 Cooperation of Parties. Thermo shall attempt in good faith and
               ---------------------
with diligence to achieve Financial Closing, but shall determine in Thermo's
discretion whether any financing opportunities which Thermo may encounter are
satisfactory to proceed to Financial Closing. Rocky Mountain shall cooperate
with Thermo in such efforts upon Thermo's reasonable request. Should any third
person contemplating providing substantial financing to Thermo (regardless of
the form or nature of such financing) and from whom Thermo has a bona fide
interest in obtaining financing (whether before or after Financial Closing)
request. as a condition of providing such financing, (a) amendments or additions
to this Agreement or the Supplemental Agreement, (b) execution of reasonable
supplemental documents for the benefit of such third person(s) or either or both
of the parties hereto, or (c) information (including business plans or other
written projections) concerning the business prospects of Rocky Mountain or
Thermo, both parties shall consider such requested amendments, additions,
supplemental documents and requests for information and shall agree to the same
unless in the discretion, reasonably exercised, of either of the parties to this
Agreement, such amendments, additions, supplemental documents, or requests for
information would materially impair the long range economic interests hereunder
of such objecting party. By way of example, and without limitation, the long
range economic interests of the parties to this Agreement would not be impaired
if, in response to a request by any such

                                      -44-
<PAGE>
 
person providing financing, the parties to this Agreement, or either of them,
would be required to forebear from pursuing any rights or remedies against the
other until such third person had received Notice of any alleged default
hereunder, and a reasonable time had expired, subsequent to receipt of such
Notice, during which time the third person providing financing had failed to
cure any default on the behalf of the defaulting party to this Agreement. The
provisions of this paragraph 21.2 are supplemented in paragraph 12 of the
Supplemental Agreement.

          21.3 Condition Precedent. The obligations of each party under this
               -------------------                                        
Agreement are further conditioned on the approval of this Agreement,
respectively, by the members of Rocky Mountain and the partners of Thermo,
acting, to the extent applicable, through their boards of directors. If such
approvals have not been obtained by both parties and Notice thereof delivered to
the other party to this Agreement within seven (7) days after the effective date
hereof, a party having obtained such approval may give Notice to the other party
that unless the other party obtains such approval within seven (7) days after
receipt of such Notice, the party having previously obtained approval may revoke
such approval and withdraw from this Agreement. Otherwise such approvals, when
obtained, shall be binding and irrevocable. If such approvals are obtained, the
Effective Date of this Agreement shall nevertheless be the date first set forth
above.

     22.  CONSTRUCTION AND INTERPRETATION
          -------------------------------

          22.1 Waivers. Any term, covenant, condition, representation, or
               -------
warranty under this Agreernent may be waived by the party entitled to the
benefit thereof, and any default in performance by one party may be waived by
the party entitled to receive such performance, but none or such provisions of
this Agreement shall be considered waived by either party unless such waiver is
reduced to writing and signed by the party entitled to such benefits. No such
waiver shall be construed as a modification of any of the provisions of this
Agreement, or as a waiver of any past or future default or breach hereof unless
as expressly so stated in such waiver.

          22.2 Survival of Covenants. All covenants and agreements and all
               ---------------------                                    
representations of either party not required by their terms to be fully
performed and discharged prior to expiration or earlier termination of this
Agreement shall survive such expiration or termination.

          22.3 Exercise of Discretion. Whenever either party shall have the 
               ----------------------                                         
right under this Agreement, either expressly or by implication, to exercise such
party's discretion in making a decision, granting or withholding an approval, or
consenting to some action on behalf of the other party, it is understood that
such discretion is absolute and the exercise thereof is not subject to review or
question for any reason, unless the contrary is expressly provided with respect
to such decision (for example, in those instances in which it is provided that
discretion is to be exercised reasonably). It is further understood that any
such decision, approval or consent by either party may be subject to the
approval, consent or ratification of the third party or parties providing
financing to the party hereto entitled to make such decision, grant or withhold
such approval, or extend such consent.

          22.4 Neither Party Drafter. This Agreement represents the culmination
               ---------------------                                        
of extensive and arms length negotiations between the parties. Neither party 
shall be deemed the drafter of this Agreement.

          22.5 Captions. Section and paragraph headings have been included in
               --------                                                    
this Agreement solely for the convenience of the reader. Such headings do not
constitute a part of this Agreement and shall be disregarded in the construction
or interpretation of this Agreement and every portion hereof.

          22.6 Certain Words and Phrases. Whenever the terms "herein," "hereof,"
               -------------------------                            
"hereunder," or words of like import are used in this Agreement, the intended
inference is to the entire Agreement and not to the clause, sentence, paragraph
or section in which such word appears. The word "paragraph" refers to a single
paragraph designated by a separate number. The word "section" refers to a
portion of this Agreement comprised of a series of one or more paragraphs
designated by the same numerical series. For example, this section 22 includes
paragraphs 22.1 through 22.9; the following section 23 consists of a single
paragraph. Pronouns of any specific gender shall be deemed to include all other
genders. The singular shall include the plural, and the plural the singular,
unless the context otherwise requires.

          22.7 Time of the Essence. Time is of the essence with respect to
               ------------------- 
all obligations and rights of the parties under this Agreement.

          22.8 Choice of Law. This Agreement shall be governed by and construed
               -------------
in accordance with the laws of the United States and of the State of Colorado,
without giving effect to conflicts of law principles thereof.  

          22.9 Agents, Consultants, and Third Persons. Whenever any right is
               --------------------------------------
conferred or reserved hereunder on or to either or both of the parties to this
Agreement, it is intended that such right may be exercised by or through an
agent or independent consultant acting on behalf of the benefitted party. It is
understood that either or both of the parties may exercise such rights from
time to time at the request of third persons who have a bona fide business
interest in the success of such party in discharging its obligations hereunder,
including without limitation third persons providing (or contemplating
providing) financing or credit to such party. No reference to the interest or
involvement of such third persons need be made in the provision or context of
this Agreement wherein such right is conferred on or reserved to a party.
Nothing in this paragraph 22.9 shall be construed to impair or conflict with any
provision of this Agreement which limits assignment, subletting, or
subcontracting of rights, or which requires that certain business information
required to be furnished or permitted to be obtained hereunder remain
confidential and not be exploited improperly by the recipient for competitive
purposes. Recipients of confidential information shall take reasonable steps to
assure that if such information becomes available to such third persons, the
third persons will respect such confidentiality and noncompetition requirements.
Nothing herein shall be construed to make any of such interested third persons
third-party beneficiaries under this Agreement.

          22.10 No Recourse Except to Contracting Parties. This Agreement is
                -----------------------------------------
entered into between a limited liability company and a partnership upon the
express agreement that notwithstanding any statute or other rule of law to the
contrary now or

                                      -46-
<PAGE>
 
hereafter in force, in the event of a breach of or default under this Agreement,
or in the event of.any other claim or cause of action arising out of or under
this Agreement or the transactions herein contemplated, the complaining party
shall have no recourse for the repayment of Damages occasioned thereby except to
the assets of the other contracting party to this Agreement. Both parties to
this Agreement covenant and agree not to seek, obtain, or in any manner attempt
to enforce against the members of Rocky Mountain or against the officers and
directors of Rocky Mountain, or against the partners (directly and indirectly)
of Thermo and the shareholders, officers, and directors of such partners, any
judgment or decree for the payment of money damages on account of any claim or
cause of action arising out of or under this Agreement or the transactions
herein contemplated.

          23.  MEMORANDUM OF AGREEMENT
               -----------------------

          A memorandum of this Agreement in proper form to give notice for
recording purposes of the demise of the Leased Premises shall be executed and,
upon commencement of the Lease Term, recorded upon request by either party. Such
memorandum may include selected thermal supply covenants, including without
limitation those which are intended to run with the land hereunder. This
Agreement shall not be recorded.

          24.  DISPUTES RESOLUTION
               -------------------

          A. Unless any third party or parties providing financing to Thermo
shall object thereto not later than upon selection of the arbitration panel as
hereinafter provided, all claims, disputes, and other matters in question
arising out of or relating to this Agreement, or the breach thereof, shall, in
lieu of court action, be submitted to arbitration in Weld County, Colorado
before a panel of three (3) arbitrators. This agreement to arbitrate shall be
specifically enforceable under the arbitration laws of the State of Colorado.
Demand for arbitration must be made within a reasonable time after the claim,
dispute, or other matter in question has arisen. In no event shall the
arbitration be made after the date when institution of legal or equitable
proceedings based on such claims, dispute, or other matter in question would be
barred by the applicable statute of limitations.

          B. The arbitrators shall be appointed in the following manner:

             (1)  The claimant shall give notice in writing to that effect to
                  the respondent and shall in such notice appoint the first
                  arbitrator to the panel.

             (2)  The respondent shall, within ten (10) days by notice in
                  writing to the claimant, appoint a second arbitrator to the
                  panel, and if the respondent shall fail to do so within the
                  ten (10) day period such appointment may (at the request of
                  the claimant) be made by any judge who is willing to so 
                  designate an arbitrator and who is at the time serving on 
                  the court of general jurisdiction for Weld County.

                                      -47-
<PAGE>
 
              (3)  The two arbitrators appointed under subparagraphs (1) and
                   (2), above, shall within ten (10) days appoint the third
                   arbitrator to the panel, and if they shall fail to do so
                   within the ten (10) day period such appointment shall (at the
                   request of either party) be made in like manner as is
                   provided for alternate appointment under subparagraph (2),
                   above.

No person shall be appointed to act as an arbitrator unless such person shall be
qualified by a minimum of ten (10) years' experience in the operation of or as a
consultant to the cogeneration or commercial greenhouse industries, or a minimum
of ten (10) years' experience in the private practice of law in a discipline
relevant to such industries. No person shall be appointed as an arbitrator if
such person is known to the party appointing the arbitrator to have some then
existing business or professional relationship with the party making the
appointment, or some interest or duty which conflicts or may conflict with such
person's duty to decide the question under arbitration fairly and objectively.
Should any arbitrator(s) be appointed who shall appear, at any time prior to the
announcement by the arbitrators of their final award, to have a conflict of
interest, the position and views of such arbitrator(s) shall be disregarded by
the other(s) and if such disregard would result in the remaining arbitrator(s)
being equally divided on the outcome, the remaining arbitrator(s) shall promptly
appoint disinterested arbitrator(s) to succeed the interested arbitrator(s)
before concluding the arbitration. Any willful attempt by either party to
conceal a conflict of interest on the part of an arbitrator appointed by such
party shall constitute fraud on the arbitration.

          C.  Notwithstanding any provisions of law or rule of arbitration to 
the contrary:

              (1)  The panel of arbitrators so appointed shall promptly fix a
                   reasonable time and place for receiving submissions or
                   information from the parties concerned or from any other
                   persons that they think fit and such panel may make such
                   other inquiries and require such other evidence as may be  
                   necessary for determining the matter before them.

              (2)  If within a period of ninety (90) days after the date of the
                   appointment of the said panel a decision shall not have been
                   rendered by the panel or a majority thereof, a new panel of
                   arbitrators shall at the request of either party be appointed
                   in the manner aforesaid and the appointment of the previous
                   panel shall thereupon cease.

              (3)  The determination of the said panel of arbitrators shall be
                   in writing and shall be final and binding upon the parties
                   concerned except in the event of fraud, or agreed mistake,
                   and judgment upon such determination rendered by the
                   arbitrators may be entered in any court of competent
                   jurisdiction. In addition to establishment and enforcement of
                   such judgment for damages as may be awarded by the
                   arbitrators, such judgment may establish the basis for entry
                   by

                                     -48-
<PAGE>
 
                   such court of an injunction, decree of specific performance,
                   order of foreclosure, or such other legal or equitable remedy
                   as it may appear to said court that the party receiving the
                   award shall be entitled to under the circumstances.

              (4)  Claimant and respondent shall each bear the costs and
                   expenses of the arbitrator appointed by it or on its behalf,
                   and also the costs and expenses of the third arbitrator shall
                   be paid by either claimant or respondent, or shall be appor-
                   tioned among parties to the arbitration in such proportions
                   as the panel of arbitrators shall in the circumstances
                   consider proper.

              (5)  Any party to the arbitration may cause to be joined in the
                   arbitration any third party who is willing to be joined and
                   whose presence in the arbitration may be necessary or
                   desirable for a complete and final resolution of the claim,
                   dispute, or other matter in question. After such joinder,
                   such third parties shall have all rights of any other party
                   to the arbitration, except that such third parties shall not
                   participate in the selection or replacement of members of the
                   arbitration panel. Refusal by such third parties to be joined
                   shall not impair the effectiveness of the arbitration as
                   between the claimant and the respondent.

              (6)  Any party to the arbitration shall be entitled, in accordance
                   with an expedited schedule which shall be determined by the
                   panel upon request by any such party, to obtain discovery
                   through depositions, interrogatories, demands for admissions
                   and requests for production and inspection of documents
                   and reports as provided for in the Colorado Rules of Civil
                   Procedure, and should disputes arise with respect to such
                   discovery procedures the party seeking discovery shall be
                   entitled to apply to the court of general jurisdiction in
                   Weld County, Colorado to enforce such rules.

              (7)  A stenographic record of all arbitration proceedings shall be
                   made upon request of any party to the arbitration, the cost
                   of which shall be shared equally among all parties, and no
                   party shall be entitled to receive a copy of the transcript
                   of proceedings except upon payment of such party's respective
                   pro rata share of such cost.

              (8)  The arbitrators shall be required to make detailed findings
                   of fact, conclusions of law, and award.

              (9)  Except as is herein otherwise expressly provided or may be
                   agreed by all parties to the arbitration, the arbitrators
                   shall be governed by the Commercial Arbitration Rules of the

                                      -49-
<PAGE>
 
                American Arbitration Association (or its successor organization)
                then in effect.

These directions for arbitration shall be interpreted under the laws of
Colorado. If at any time it is not possible to establish an arbitration in
accordance with the foregoing, arbitration shall nevertheless be conducted in
accordance with substitute procedures which shall be as nearly as may be
practical in accordance with these prescribed procedures, and resort may be had
to the court of general jurisdiction of Weld County, Colorado to establish the
same.

          25.  INTEGRATION: AMENDMENT

part (which is not cured within the grace period, if any, applicable thereto)
under or pursuant to any of such obligations shall constitute a default under
this Mortgage.

          2. Covenant of Title. Mortgagor, for itself and its successors and
             ------------------                                            
assigns covenants and agrees to and with Mortgagee, its successors and assigns,
that it holds the said Property by title in fee simple; that it has good right
and lawful authority to sell and convey the same; that said Property is free and
clear of all liens and encumbrances whatsoever, except those matters described
on Exhibit B hereto and by this reference made a part hereof; and that except
as aforesaid, Mortgagor will warrant and defend said Property against the lawful
claims of all persons claiming by, through, or under it. Mortgagee shall permit
no superior or subordinate Mortgage, Deed of Trust or other financing
encumbrances to exist with respect to the Property except as is permitted under
paragraph 5.8 of the Thermal Lease Agreement.

          3.   Default. Each of the following events shall constitute a default
               --------                                                        
hereunder:

               (a)  Failure of Mortgagor to fully and faithfully perform each 
andevery term and condition to be performed by it under any one or more of the
Secured Obligations;

               (b)  The occurrence of any default under any encumbrance on all
or any part of the Property which has priority over the lien of this Mortgage,
or the creation of any encumbrance subsequent to the date hereof, except as
permitted under paragraph 5.8 of the Thermal Lease Agreement;

               (c)  Failure by Mortgagor to comply with or observe any term,
covenant, warranty or representation contained in this Mortgage;

               (d)  Failure by Mortgagor to comply with the provisions of the
Declaration of Restrictive Covenants recorded on       in Book      , at
Page      Reception No.    of the records of                 County, Colorado, 
the terms of which encumber and restrict the use of the Property.

          4.   Mortgagee's Right to Cure or Perform. In the case of any default
               -------------------------------------                          
herein, Mortgagee may, but need not, make any payments or perform any actions,
including the purchase, discharge, and compromise of any prior encumbrance,
which are necessary or required to cure such default or protect the security of
this Mortgage. All monies paid for the purposes herein authorized and all
reasonable expenses of any such performance, including reasonable attorneys'
fees, shall be included as additional indebtedness secured hereby, and shall
become immediately due and payable with interest

                                    D - 3
<PAGE>
 
thereon at the lesser of eighteen percent (18%) per annum or the highest non-
usurious rate for commercial transactions permitted by Colorado law. Inaction of
Mortgagee shall never be considered as a waiver of any right accruing to it on
account of any default hereunder on the part of Mortgagor.

          5. Mortgagee's Remedies. In the event of any default hereunder,
             ---------------------                                      
Mortgagee, its successors or assigns, may, at its sole option, elect to
foreclose this Mortgage. Following the occurrence of a default, Mortgagee or the
holder of the certificate of purchase after a foreclosure sale, acting by and
through a Receiver appointed in accordance with law, shall at once become
entitled to the possession, use and enjoyment of the Property, and to the rents,
issues and profits thereof, from the date of occurrence of the default and
during the pendency of foreclosure proceedings and the period of redemption, if
any there be; and such possession shall at once be delivered to such Receiver
appointed in accordance with law; and Mortgagee, or the holder of said
certificate of purchase, shall be entitled to a Receiver for said Property and
of the rents, issues and profits thereof, whether or not foreclosure proceedings
have been commenced, and without regard to the solvency or insolvency of
Mortgagor or of the then owner of said Property and without regard to the value
thereof, and such Receiver may be appointed by any court of competent
jurisdiction upon ex parte application and without notice; and all rents, issues
                  -- -----
and profits, income and revenue therefrom shall be applied by such Receiver to
the payment of the damages occasioned by Mortgagee on account of such default,
according to law and the orders and directions of the Court.

          6. Partial Foreclosures. In the event Mortgagee elects to foreclose
             ---------------------                                          
this Mortgage, such election may  be made in Mortgagee's sole discretion, with
respect to any one or more defaults together with fees, costs, advancements and
expenses incurred with respect to such defaults. Such foreclosure shall not
affect the lien of this Mortgage as to any remaining obligation or any part of
any such obligation, which is secured hereby but not covered by such
foreclosure, and which does not become due prior to the commencement of such
foreclosure proceedings. Any such foreclosure shall not extinguish the lien of
this Mortgage, but title acquired by such foreclosure shall be subject to the
lien of this Mortgage for all remaining obligations secured hereby. A redemption
from any such foreclosure shall have the same effect as if the foreclosure had
been that of an independent mortgage; and if Mortgagee acquires title conveyed
by virtue of any such foreclosure, the title evidenced by this Mortgage shall
nonetheless continue to secure the lien for the remaining obligations and shall
not merge with the title acquired by such foreclosure. Mortgagee expressly
acknowledges and agrees that the limitations on foreclosure set forth in Section
38-38-201, Colorado Revised Statutes, are inapplicable to this Mortgage.

          7. Expenses of Foreclosure and Litigation. In the event of foreclosure
             ---------------------------------------                           
of the lien hereof, there shall be allowed and included as additional
indebtedness all reasonable expenditures and expenses which may be paid or
incurred on behalf of Mortgagee for attorneys' fees, appraiser's fees, outlays
for documentary and expert evidence, stenographer's charges, publication costs
(which may be estimated as to items to be expended after foreclosure sale or
entry of the decree) of procuring all such abstracts of title, title searches
and examinations, title insurance policies and similar data assurances with
respect to title as Mortgagee may deem reasonably necessary either to prosecute
such suit or to evidence to bidders at any sale which may be had pursuant to
such decree the true condition of title to or the value of the Property. All
expenditures

                                 D - 4
<PAGE>
 
and expenses of this nature in this paragraph mentioned, and such reasonable
expenses and fees as may be incurred in the protection of said Property, the
maintenance of the lien of this Mortgage, including the reasonable fees of any
attorney employed by Mortgage in any litigation or proceeding affecting this
Mortgage, or said Property, including probate and bankruptcy proceedings, or in 
preparation for the commencement or defense of any proceeding or threatened
suit or proceeding, shall be immediately due and payable by Mortgagor, with
interest thereon, at the rate equal to the lesser of eighteen percent (18%)
per annum or the highest non-usurious rate permitted by Colorado law, and shall 
be secured by this Mortgage.

        8. Binding on Successors and Assigns. This Mortgage and all provisions
           ----------------------------------                                
hereof, shall extend to and be binding upon Mortgagor and all persons claiming
under or through Mortgagor, whether or not such persons have executed this
Mortgage, and the terms of this Mortgage shall inure to the benefit of Mortgage
and its successors and assigns. Nothing herein contained, however, shall be
deemed to authorize any conveyance or encumbrance of the Property by Mortgagor
except in accordance with the Thermal Lease Agreement.

        9. Captions: Definitions. The captions and headings of various          
           ---------------------                                    
paragraphs of this Mortgage are for convenience only and are not to be construed
as defining or limiting in any way the intent of the provisions hereof.
Capitalized terms used herein but not defined herein shall have the meaning
given to such terms in the Thermal Lease Agreement.

       10. Law. This instrument has been executed in Colorado and shall be
           ---
governed by and construed in accordance with the laws of the State of Colorado.

       11. No Merger. In the event Mortgagee acquires any interest in the
           ---------                                                   
Property whether subordinate or superior to the lien of this Mortgage at any
time prior to the full performance of the obligations described herein, it is
the intent of Mortgagor and Mortgagee that such other interest shall not be 
merged with any interest of Mortgagor acquired by reason of the grant of this 
Mortgage.

        IN WITNESS WHEREOF, Mortgagee has hereunto set its hand the day and
year first above written.

                                   Aluminium
                                   ---------

Roof: Dalsem system 
Aluminium standard roof, type 3,2 mtrs. Venlo. The roof is composed
of aluminium profiles such as ridges, reinforced glazing bars
(snowload 50 kg), gutter edges with a roof pitch of 22 deg. suitable
for glass sizes 165 X 100 cm.
According the Dutch standards, the roof is mounted storm-tight with
the following materials:
- -ridge clips for the connection glazing bar - ridge
- -gutter clamps for the connection gutter - glazing bar
- -a double ridge catcher per gable-end of 3,2 mtrs. and near
 all 3 expansion joints on both sides.
- -gutter-ridge-gutter connections
 positions: - above the first trellis girder at both gable ends
              and between the ridge catchers at gable ends.
            - above each trellis of the first and the last span
              of 3,20 mtrs. and near expansion joint.

The whole roof construction complies with the Dutch standard 
specification NEN 3859. TNO-IBBC approved report no: B88-669 
(glass 1,00 mtr. APD gutter).

Gables, partition (corridor(s) and sides
The side walls, gable ends and corridors are composed of aluminium
profiles such as wall plates, gutter edge profiles, vertical glazing
bars and horizontal glazing bars. This rubber capped glazing system
increases the stability of the greenhouse and improves the air 
tightness.
The greenhouse corners are finished with special aluminium corner
profiles. The glazing bars are suitable for double glazing, glass
width: 78,40 cm.

Expansion joints
One expansion joint (30 cm) is projected one in the centre of the
greenhouse 30x6,4 straight after the partition gable.
This joint is closed with a special expansion rubber between the
profiles.
As the dutch Nen standaards admit greenhouses to be max. 200 mtrs. in
length, the greenhouse is split into two areas divided by the above
described expansion (dilitation) joint. Due to the fact that the
total length of the two areas will be 2x 204 mtrs. the greenhouse
still does not pass the Dutch Nen standards on this point. To compen-
sate the above, two extra expansions will be projected in the roof
and gables allowing the expansion and contraction however the gutters
will not be split at these two joints, enabling an eventual roof
cleaner to pass these joints.

Adjacent to the partition gable (drainposts) the next (dititated)
area will start with posts every 3,20 mtr. (drainposts) and be fitted 
with screening purlins and crop supports.

fitted by aluminium brackets at the uprights and the roof glazing
bars and bushed at the ridge.  The sprinklers are fitted right on top 
of the ridge and will not protrude more than 30 cm in order not to
hinder the eventual greenhouse roof cleaner.

The 63 mm p.v.c. pipes are installed in the ground. They are joined 
with 1,5" valve sets.  Our supply includes 12 valve sets in all.

Each valve set is composed of the following elements:

- - one take off point 50 mm x 1,5" for draining of the pipes
  (frost prevention)
- - a p.v.c. ball valve 32 mm with half Geka 1" coupling
  (watering tap).

The valve sets are connected to the main supply.
The 110 mm p.v.c. main supply pipe is installed underground along the
pathway and connected on pump station in the substrate room.

The pumpstation is assembled of a stainless steel frame with 
1 Lowara pump type CN 40-160 of 4,0 KW (5,5 HP) 480 V - 60 Hz and a
2" filter, make UDI with stainless steel 300 micron strainer.

The pump capacity is sufficient to control 1 valve at each time.

The following pipework is connected to the pumps:

                           DECLARATION OF COVENANTS
                           ------------------------


     THIS DECLARATION is made as of the ____ day of __________, 19__, by THERMO 
COGENERATION PARTNERSHIP, a Colorado partnership, hereinafter referred to as 
"Declarant."

     
                             W I T N E S S E T H:
                             - - - - - - - - - -

     
     WHEREAS, Declarant is the owner of certain real property located in the 
County of Weld, State of Colorado, which is more particularly described on 
Exhibit "A" hereto ("Cogeneration Site"), upon which Declarant intends to 
construct and operate a cogeneration plant; and

     WHEREAS, Declarant is also the owner of certain real property located in 
the County of Weld, State of Colorado, which is more particularly described in 
Exhibit "B" hereto ("Greenhouse Site"), upon which Declarant intends to 
construct and lease to others a commercial greenhouse; and

     WHEREAS, the cogeneration plant will be constructed with the intention of 
supplying the thermal energy requirements for the operation of the commercial 
greenhouse; and

     WHEREAS, Declarant would not construct the cogeneration plant but for the 
obligation of the Greenhouse Operator (hereinafter defined) to purchase and use 
thermal energy produced by the cogeneration plant in the operation of the 
commercial greenhouse for a continuous period of twenty-five (25) years from the
initial date of commercial operation of the cogeneration plant; and

     WHEREAS, Declarant desires that the Greenhouse Site shall be held, leased 
and used subject to the following covenants, conditions and restrictions for the
purpose of protecting the value and desirability of the Cogeneration Site.

     NOW, THEREFORE, Declarant, for itself, its successors and assigns, declares
as follows:

     1.   Definitions
          -----------

          A.   The term "Declarant" shall include Thermo Cogeneration 
Partnership and any successors and subsequent owners of the Cogeneration Site 
for so long as it owns the Cogeneration Site.

          B.   "Greenhouse Operator" shall mean the party or parties operating 
the greenhouse and shall include, without limitation any party or parties owning
fee title to the Greenhouse Site and for any improvements erected thereon.

                                      H-3
<PAGE>
 
        2.     Restriction on Use.  The Greenhouse Site shall be used and
               ------------------
operated only as a commercial greenhouse for the production of agricultural
products, or for such alternative uses (which must in any event require
consumption of thermal energy) as may be approved by Declarant prior to any
change in use, which approval by Declarant shall not be withheld or delayed
unreasonably.

        3.     Covenant to Operate.  The Greenhouse Operator shall use and
               -------------------
operate the Greenhouse Site for the permitted purposes described in paragraph 1 
hereof.  Such operations shall be conducted in accordance with the terms and 
conditions of a certain Thermal Supply Lease Agreement dated as of March 15, 
1993, under which Declarant is the lessor and Greenhouse Operator is the lessee
(the "Thermal Supply Agreement"); provided however that the term of Greenhouse
Operator's leasehold estate shall not commence until the occurrence of the 
Commencement Date as provided in the Thermal Supply Lease and that this         
Declaration of Covenants shall not be construed to have effected any demise
of the Greenhouse Site or to constitute actual or constructive notice of
any such demise.  In connection with the operation of the Greenhouse Site,
the Greenhouse Operator shall, subject to the terms of the Thermal Supply 
Agreement and conditions of Force Majeure as therein provided, accept a
quantity of thermal energy from the Cogeneration Site of not less than
Two Hundred Billion (200,000,000,000) BTU measured on an annual calendar
year basis, which thermal energy shall be received through a heat transfer
system.  To the fullest extent reasonably practicable, thermal energy
prepared on the Cogeneration Site shall be utilized on the Greenhouse 
Site in lieu of thermal energy obtained from alternate sources.  In addition, no
other source of thermal energy (except solar generated radiant energy) shall
be utilized on the Greenhouse Site in connection with the operation of the
permitted use so long as thermal energy sufficient to satisfy the needs of the
operation is produced and made available from the Cogeneration Site.

        4.     Appointment of Receiver.  In addition to any other rights and 
               ----------------------- 
powers conferred on the Declarant, it shall have the right after the breach of
any of the covenants herein to apply for the appointment of a receiver for the
Greenhouse Site with the power to enter upon, take possession and control of and
operate the Greenhouse Site for the permitted use herein described, and with
such other powers as may be deemed necessary to perform its duties. Declarant
shall be entitled to such receiver as a matter of right, and shall be entitled
to apply for such receiver ex parte and without
                           --------
prior notice to Greenhouse Operator.  Any receiver so appointed shall apply any 
income from the operation of the Greenhouse Site first to the necessary expense
of continuing the operation, then to the reasonable costs of the receivership,
and the balance shall be held and applied as directed by the court.

        5.     Enforcement.  In any legal or equitable proceeding for the
               -----------
enforcement (or to restrain the violation) of this Declaration in any provision 
hereof, the losing party shall pay the reasonable attorneys' fees of the 
prevailing party, and such amount shall be assessed as part of any judgment or 
order entered by the court hearing the dispute.  All remedies provided herein or
at law or in equity shall be cumulative and not exclusive.  The failure of 
Declarant to enforce any of the covenants herein contained shall in no event be 
deemed to be a waiver of the right to do so for subsequent violations.

                                     H - 4

<PAGE>
 
        6.     Term.  This Declaration, every provision hereof and every 
               ----
covenant contained herein shall continue in full force and effect for a period 
twenty-five years from the initial date of commercial operation of the 
cogeneration plant, unless prior thereto the Declarant and the Greenhouse Opera-
tor shall execute and record in the real estate records of Weld County,
Colorado, a written instrument acknowledging the earlier termination hereof. The
date of initial commercial operation of the cogeneration plant shall be deemed
to be the date set forth on a certificate which may be filed in the real estate
records of such county by the Declarant within five (5) years after the date of
filing hereof. Otherwise, such date shall be deemed to be the twenty-fifth
(25th) anniversary of the filing in such real estate records of this
Declaration.

        7.     Inurement.  The covenants herein contained shall bind Declarant
               ---------
and Greenhouse Operator during the periods in which they shall own their 
respective sites, and thereafter shall bind and inure to the benefit of their 
respective successors and assigns.

        8.     Severability.  If any of the provisions of this Declaration or
               ------------ 
the application thereof in any circumstances shall be invalidated, such 
invalidity shall not affect the validity of the remainder of this Declaration or
the application thereof in other circumstances.

                    MEMORANDUM REGARDING ADJUSTMENT OR RENT
                               AND OPTION PRICE


Subject:     Thermal Supply Lease Agreement dated as of March 22, 1993 
             (the "Thermal Lease Agreement")

Parties:     Thermo Cogeneration Partnership, a Colorado partnership ("Thermo")

             Rocky Mountain Produce Limited Liability Company, a Colorado
             limited liability company ("Rocky Mountain")

Date:        March 25, 1993

             1.   Reference is hereby made to the Thermal Lease Agreement.
Capitalized terms used in this memorandum have the meanings given to such terms
in the Thermal Lease Agreement. The parties desire to supplement their
agreements and understandings set forth in the Thermal Lease Agreement as
expressly provided in this memorandum.

             2.   Base Rent payable under paragraph 4.1 of the Thermal Lease
Agreement and the Option Purchase Price set forth on Exhibit C of the Thermal
Lease Agreement have been determined on the assumption that the final Contract
Sum (inclusive of the Contractor's fee under the Construction Contract) for
construction of (and therefore the investment of Thermo in) the Facility will be
Seven Million Eight Hundred Thousand Dollars ($7,800,000). Such Base Rent and
Option Purchase Price also have been determined on the premise that a reasonable
return on Thermo's investment in the Facility should approximate the average
annual rate of interest (not presently capable of final determination) which
Thermo will be required to pay for the definitive
<PAGE>
 
construction/start-up and term financing to be obtained by Thermo for 
construction and start-up of the Plant and the Facility, multiplied by Thermo's 
then-unrecovered investment from the Facility, plus recovery by Thermo of its 
capital investment in the Facility over a period of not longer than twenty (20) 
years after the initial Date of Commercial Operation. Thermo has estimated such 
average annual rate of interest to be nine and eighty-nine one-hundredths 
percent (9.89%) per annum, and this rate of return has been used in a proforma 
calculation of Base Rent payable under paragraph 4.1 and the Option Purchase 
Price set forth on Exhibit C.

     3.  If feasible to do so consistent with Rocky Mountain's operating 
requirements, the parties agree to use their best efforts to reduce the Cost of 
the Work (as defined under the Construction Contract) so that the final Contract
Sum shall be less than $7,800,000. This best efforts obligation shall not 
require either party to agree to any change with respect to which such party is 
given a right of prior approval under paragraph 6.3 of the Thermal Lease 
Agreement or the Construction Contract or to require Rocky Mountain to agree to 
a reduction in the Contractor's Fee, unless such reduction is required pursuant 
to those provisions of the Construction Contract under which the final payment 
to the Contractor is to be determined, and adjusted if necessary.

     4.  Thermo agrees that promptly after conversion of the construction/start-
up financing for the Plant and the Facility to term loan financing, Thermo shall
in good faith determine as accurately as is practicable the actual average
annual rate of interest which Thermo has been and will be required to pay for
financing for the construction/start-up and term financing for the Plant and the
Facility. For purposes of determining the average annual rate of interest, loan
"points," loan fees paid to the lender, and similar charges in the nature of
prepaid interest paid to the lender and reasonably allocated to obtaining such
financing shall be deemed to be interest costs. If either the final Contract Sum
is other than $7,800,000, or such


                                       2
<PAGE>
 
actual average annual rate is less than 9.89% per annum, Thermo shall 
redetermine Base Rent payments required to be made during the first twenty (20) 
years of the Lease Term according to the following formulae:

           (a)   Quarterly Base Rent payment = level quarter-annual
                 payment required to completely amortize in 77 payments the
                 amount which is the sum of (i) the final Contract Sum, plus
                 (ii) interest on the unamortized balance of the final Contract
                 Sum from time to time outstanding at the actual average
                 annual rate of interest (all sources blended on an equitably 
                 weighed average basis) paid by Thermo, but not greater than
                 9.89% per annum.

           (b)   Total Base Rent = sum of all Quarterly Base Rent
                 payments, i.e. seventy-seven (77) times the Quarterly Base
                 Rent payment.

           Where:  the actual average annual rate of interest is determined
           -----
           based on an equitably weighted average rate of interest on all
           borrowings of funds by Thermo and the partners and Affiliates of
           Thermo specifically for use in development, construction and
           operation of the Plant and the Facility.

The foregoing redetermination of Base Rent shall be made from time to time in 
the event of any general refinancing of the Plant and the Facility by Thermo.

           5.    If the Base Rent is revised, the Purchase Option Price Schedule
(Exhibit C) shall also be revised to change the Base Purchase Price set forth 
therein to the actual Contract Sum (prior to the first Quarterly Payment Date), 
with such Base Purchase Price declining, on a quarter-by-quarter basis in the 
manner presently set forth in such Exhibit C, so that such Base Purchase Price 
will always equal the unamortized principal balance of the final Contract Sum
based on a complete amortization, in seventy-seven (77) equal quarterly 
installments (level combined principal and interest basis), of the Contract Sum,
at the actual average rate of interest for the initial construction/start-up and
term financing used to redetermine the Quarterly Base Rent Payment.

                          AND CONSENT TO ASSIGNMENT

     THIS SUPPLEMENTAL AGREEMENT AND CONSENT TO ASSIGNMENT ("Supplemental 
Agreement"), effective as of the ___ day of March, 1993, by and between THERMO 
COGENERATION PARTNERSHIP, L.P., a Delaware limited partnership ("Thermo"), and 
ROCKY MOUNTAIN PRODUCE LIMITED LIABILITY COMPANY, a Colorado limited liability 
company ("Rocky Mountain"), and THE PRUDENTIAL INSURANCE COMPANY OF AMERICA, as 
a lender (hereinafter, together with any successors or assigns in such capacity,

                                   RECITALS:

     A.  On March __, 1993, Rocky Mountain entered into with Thermo Cogeneration
Partnership, a Colorado partnership, a Thermal Supply Lease Agreement (the
"Assigned Agreement"), which Assigned Agreement contains, among other things,
the agreement of the parties as to (i) the construction of a twenty (20) acre
(more or less) commercial greenhouse (the "Facility") on certain real property
(the "Land") owned by Thermo
<PAGE>
 
in Fort Lupton, Colorado, (ii) the leasing of such Land and the Facility by 
Thermo to Rocky Mountain, (iii) the operation of the Facility by Rocky Mountain 
for the commercial production of agricultural products, and (iv) the agreement

"Project Site") of which the Land is part;

           B.  In order to facilitate financing and construction of the Plant 
and the Facility, Thermo Cogeneration Partnership has assigned the Assigned 
Agreement to Thermo, and Thermo, acting in the capacity of borrower, has entered
into the Loan Agreement. Thermo has also, in accordance with the requirements of
the Loan Agreement, collaterally assigned all of its right, title and interest 
in, to and under the Assigned Agreement to Lead Agent pursuant to the Collateral
Assignment dated as of March __, 1993 (the "Collateral Assignment"). It is a 
condition precedent to the initial funding by Lenders under the Loan Agreement 
that Rocky Mountain execute and deliver this Supplemental Agreement.

           C.  Pursuant to that certain Project Management Agreement dated as of
December 21, 1992 (the "Project Management Agreement") between Thermo Project 
Management, Inc., a Colorado corporation ("Project Manager"), and Thermo (as 
assignor or successor to Thermo Cogeneration Partnership), Thermo has appointed 
Project Manager as its agent to carry out and enforce the Assigned Agreement 
within the scope of Project Manager's obligations under the Project Management 
Agreement.

           D.  The Loan Agreement contains certain terms and conditions that, 
during its term, will impact not only Thermo, but also Rocky Mountain as lessee 
and Facility Operator under

                                       2
<PAGE>
 

the Assigned Agreement, and will place certain restrictions and impose certain 
obligations on Thermo as lessor and owner and Rocky Mountain as lessee and 
operator with respect to the construction, leasing, and operation of the 
Facility and the Plant; and

      E. By entering into this Supplemental Agreement, the parties desire to 
(i) acknowledge the existence of such terms and conditions in the Loan 
Agreement, (ii) supplement the terms of the Assigned Agreement in certain 
instances in which the Loan Agreement contains additional or more detailed terms
and conditions dealing with similar subjects as dealt with in the Assigned
Agreement, and (iii) provide in certain instances that the terms and conditions
of this Supplemental Agreement and the Loan Agreement shall, to the extent
specifically expressed herein, supersede and prevail over any conflicting
provisions of the Assigned Agreement.

      NOW, THEREFORE, in consideration of the premises and the mutual promises 
and covenants contained in this Supplemental Agreement, the parties agree as 
follows:

      1.  Definitions. Capitalized terms used herein (including in the schedules
          -----------
attached hereto) have the meanings set forth herein, or if not defined herein
the meanings set forth in the Assigned Agreement, and if not defined herein or
in the Assigned Agreement, in the Loan Agreement. The Secured Parties (as
defined in the Loan Agreement) are sometimes referred to herein as "Assignee".

      2.  Term. This Supplemental Agreement shall remain in full force and
          ----
effect for the benefit of Lead Agent and the lenders under the Loan Agreement, 
and their respective successors and assigns, until the earlier of expiration or 
earlier termination of all obligations of Rocky Mountain under the Assigned 
Agreement, or until such time as all loans, commitments, and obligations 
incurred by Thermo under the Loan Agreement, the Notes, or any collateral or 
other documents

                                        3
<PAGE>
 


entered into in connection herewith (the "Obligations") have been fully paid and
performed ("Termination"); provided however, that the provisions of section 6 of
this Supplemental Agreement shall survive the expiration or complete termination
of the Assigned Agreement; and, provided further, that if the Lead Agent or the
lenders shall initiate action because of an Event of Default by Thermo under the
Loan Agreement, and as a result of such action the rights of Thermo in the
Facility, the Land, the Plant, or the Project Site shall be terminated by
foreclosure or otherwise, any assignee or any transferee of the rights of Thermo
in the Facility, the Land, the Plant, or the Project Site shall also be entitled
to enjoy the benefits of, and to exercise the rights conferred on, the Lead
Agent and the lenders under such section 6. From and after the time of
Termination, the matters, covered by this Supplemental Agreement shall be
governed solely as provided in the Assigned Agreement, as the same may have been
amended in the interim, and this Supplemental Agreement shall automatically
become null and void and be of no further force and effect, except as is
otherwise provided in the preceding sentence. Any extension of time for payment
or performance of the Obligations, whether by amendment, modification or
supplementation of the Loan Agreement or otherwise, shall extend the time for
Termination. After Termination, neither the prior effectiveness of this
Supplemental Agreement nor the text of any provision herein which does not
expressly survive such termination shall have any effect whatsoever on the
construction or interpretation of the Assigned Agreement.

be discharged by Rocky Mountain to the same extent and in the same manner as is

     4.  Option to Purchase Suspended.  Anything in the Assigned Agreement to 
         ----------------------------
the contrary notwithstanding, Rocky Mountain shall not be entitled to exercise 
the rights conferred under section 5 or be deemed to have exercised such rights 
under section 12 of the Assigned Agreement to purchase the Facility (or the 
Land) at any time there remains unpaid any indebtedness under the Loan Agreement
unless, at the time of such exercise, Thermo shall have obtained Prudential's 
approval (which approval may be withheld in Prudential's sole discretion) of 
alternative thermal use arrangements, including all appropriate regulatory and 
administrative approvals and filings, for thermal energy produced by the Plant. 
Thermo shall from time to time inform Rocky Mountain upon inquiry whether any 
such indebtedness is outstanding. Upon receipt of a notice by Rocky Mountain 
of its intention to exercise its rights under section 5 of the Thermal Supply 
Agreement, 


                                       8
<PAGE>
 
Thermo shall notify Rocky Mountain whether Thermo shall have obtained 
Prudential's approval of alternative thermal use arrangements and, if so, 
the purchase price payable by Rocky Mountain. Such price shall be the "Option 
Purchase Price," determined in the manner provided in paragraph 5.2 of the 
Assigned Agreement, plus such additional sum as may be payable pursuant to 
paragraph 5.5 of the Assigned Agreement should Rocky Mountain also purchase the 
Land as provided in such paragraph. At the closing of such sale, Thermo shall 
obtain from Lead Agent and deliver to Rocky Mountain a Release by Lead Agent 
from the lien of any mortgage(s), deeds of trust, and other security agreements 
encumbering the Facility (and the Land if purchased) to secure repayment of the 
indebtedness of Thermo under the Loan Agreement and Rocky Mountain shall deliver
to Thermo and Lead Agent a ratification and reaffirmation of all thermal supply 
provisions of the Assigned Agreement in such form as Thermo or Lead Agent may 
reasonably request. Nothing herein shall be construed to relieve Rocky Mountain
of its obligations under paragraph 5.8 of the Thermal Supply Agreement. Under no
circumstances shall Rocky Mountain be entitled to exercise the Purchase Option
at any time while Thermo is in default under the Assigned Agreement or this
Supplemental Agreement or while an Event of Default is continuing under the Loan
Agreement. Should the lenders, the Lead Agent or their nominee exercise any
remedies arising because of an Event of Default by Thermo under the Loan
Agreement whereby Thermo's rights in the Facility, the Land, the Plant or the
Project Site shall be terminated, assumed or transferred, the Purchase Option,
effective as of the time of such exercise, shall permanently lapse and become
void and shall no longer be binding upon Thermo, the Lead Agent, any lender
under the Loan Agreement or any transferee of the Facility, the Land, the Plant
or the Project Site in connection with such exercise of rights or remedies
because of such Event of Default.

<PAGE>
 


       5. Reports, Information and Approvals. At all times while indebtedness is
          ----------------------------------
outstanding under the Loan Agreement:

          5.1  Lead Agent shall have the same rights as Thermo to receive 
reports and information as shall be available to Thermo, and to exercise other 
rights with respect to receipt of information as are conferred on Thermo under 
paragraphs 8.11 and 8.12 of the Assigned Agreement. Rocky Mountain shall deliver
all such reports and information to Lead Agent at the address set forth in 
paragraph 14 hereof, or such other address as Lead Agent may have specified 
pursuant to such paragraph.

          5.2  Notwithstanding paragraphs 14.1 and 14.2 of the Assigned 
Agreement, Rocky Mountain shall make or agree to make any proposed assignment, 
sublease or subcontract under the Assigned Agreement without the prior written 
consent of Thermo, which consent may be withheld in Thermo's sole discretion.

      6.  Environmental Matters.  Supplementary to and not in lieu of Rocky
          --------------------- 
Mountain's obligations under paragraph 10.1 and certain other provisions of the 
Assigned Agreement:

          6.1  Rocky Mountain shall at all times comply fully with all laws, 
rules, regulations, and ordinances of any public authority having jurisdiction 
with respect to the storage, use or release at the Facility and on the Land of 
hazardous or toxic substances, and shall not treat, store, transport or release 
any Materials of Environmental concern on or from the Facility or the Land in 
any manner or quantity which may result in any clean-up obligation or liability 
under any Environmental Law; shall keep the Facility free of any lien imposed 
pursuant to Environmental Laws because of acts or omissions of Rocky Mountain or
its Affiliates, agents, employees, contractors,

                                        10
<PAGE>
 


sublessees, successors or assigns: and shall pay or cause to be paid when due
any and all costs of complying with Environmental Laws and responding to the
presence, release, or threatened release of Materials of Environmental Concern
because of acts or omissions of Rocky Mountain or its agents, employees,
contractors, sublessees, successors or assigns (including without limitation all
damages, liabilities, expenses and costs of all third-party claims). If Rocky
Mountain fails to do any of the foregoing, then to the extent that Thermo, Lead
Agent or any lender under the Loan Agreement and their respective partners,
shareholders, directors, officers, agents, employees, successors or assigns
sustains any liability, loss, cost, damage, or expense (including attorneys' and
consultants' fees and expenses) arising out of the presence, release, or
threatened release by Rocky Mountain or its Affiliates, agents, employees,
contractors, sublessees, successors or assigns of Materials of Environmental
Concern on or from the Facility or the Land, Thermo, Prudential or Lead Agent
may, upon such prior written notice to Rocky Mountain as is reasonable under the
circumstances, take any action necessary, in the reasonable judgement of such
responding party, to respond to such presence, release or threatened release,
and the cost of such response action shall be borne by Rocky Mountain. Rocky
Mountain shall give to Thermo, to Prudential and to Lead Agent, and to their
respective officers, agents, employees and contractors, access to the Facility
and the Land, and Rocky Mountain hereby specifically grants to Thermo, to
Prudential and to Lead Agent a license to respond to such presence, release, or
threatened release of such Materials of Environmental Concern.

        6.2  In addition to the requirements of paragraph 10.1 of the Thermal 
Supply Agreement, Rocky Mountain shall indemnify and hold Thermo, Lead Agent, 
Prudential and each other lender under the Loan Agreement and their respective 
partners, shareholders, directors, officers, agents or employees free and 
harmless from and against all liability, loss, cost, damage,

                                11

and expense (including without limitation attorneys' and consultants' fees and
expenses) incurred in connection with the environmental compliance, clean-up and
other response obligations imposed under any Environmental Laws or in connection
with third-party claims relating to or in connection with any violation by Rocky
Mountain or its Affiliates, agents, employees, contractors, sublessees,
successors or assigns of any Environmental Law or in connection with any
Materials of Environmental Concern used, generated, treated, stored, or
otherwise located on, or released by Rocky Mountain or threatened to be released
in, on, under, from or affecting the Facility or the Land, except to the extent

<PAGE>
 
Thermo or Lead Agent, continue performance under the Assigned Agreement in

References herein to Thermo shall include, without limitation, Project Manager

        13.  No Present Defaults. Rocky Mountain acknowledges that (a) the

Assigned Agreement is in full force and effect and there are no amendments,
modifications or supplements thereto, either oral or written, (b) Rocky Mountain
has not assigned, transferred or hypothecated the Assigned Agreement or any
interest therein, except as described herein, (c) Rocky Mountain has no
knowledge of any default or breach by Thermo in any respect in the performance

and hereby ratifies prior assignments to Thermo of the Assigned Agreement
whereby Thermo has acquired rights under the Assigned Agreement and releases all
prior assignors of the Assigned Agreement from their obligations as parties to

        14.  Notice of Thermo's Defaults and Termination. Anything in the 
             -------------------------------------------
Assigned Agreement notwithstanding, Rocky Mountain shall not claim prevention of
or interference with performance of its obligations pursuant to the Assigned
Agreement or the suspension or termination of its obligations under the Assigned
Agreement as the result of any default of Thermo without first giving a copy of
any notice of default or termination to Lead Agent, such notice to be coupled
with a request to Lead Agent to cure any defaults which are susceptible of being
corrected by Lead Agent, within a cure period as provided to Thermo in the
Assigned Agreement plus a period of ninety (90) days (thirty (30) days in the
case of a monetary default) thereafter (or, with respect to any defaults not
susceptible of being cured within such cure period, such longer cure period as
shall be required to cure such default provided that Lead Agent is diligently
pursuing such cure), such cure period to


                                      17
<PAGE>
 
commence upon such notice to Lead Agent, or, with respect to any defaults which 
are not susceptible of being corrected by Lead Agent, to rectify to Rocky 
Mountain's reasonable satisfaction the effect upon Rocky Mountain of such 
default by Thermo within such period. Such notice shall be in writing and shall 
be deemed to have been given (a) when presented personally or by Federal Express
or other courier, (b) when transmitted by telecopy to the number specified 
below, or (c) when received, if deposited in a regularly maintained receptacle 
for the United States Postal Service, postage prepaid, registered or certified 
mail, return receipt requested, addressed to Lead Agent and Prudential at the 
address indicated below (or such other address as Lead Agent or Prudential may 
have specified by written notice delivered in accordance herewith). The telecopy
(facsimile) numbers provided below are for the convenience of Rocky Mountain 
only. Transmission by telecopy shall constitute provision of notice under this 
Supplemental Agreement only if receipt thereof is acknowledged in writing by 
Prudential or Lead Agent, as the case may be, within such period. The address 
for notices to Prudential and Lead Agent is as follows:

                The Prudential Insurance Company of America
                c/o Prudential Power Funding Associates
                Four Gateway Center
                100 Mulberry Street
                Newark, New Jersey 07102-4069
                Attention: Project Management Team
                Facsimile No.: (201) 802-2841

No claim of rescission or termination of the Assigned Agreement by Rocky
Mountain shall be binding upon Prudential or Lead Agent without such notice and
the lapsing of the applicable cure period. Any dispute that may arise under the
Assigned Agreement notwithstanding, Rocky Mountain shall continue performance
under the Assigned Agreement and resolve any such dispute without discontinuing
such performance until the lapse of the notice and the applicable cure periods
or extension periods. Lead Agent may, but shall be under no obligation to, make
any payment or perform any act required thereunder to be made or performed by
Thermo, with the same effect as


                                      18
<PAGE>
 
if made or performed by Thermo. If Lead Agent or Prudential fails to cure a 
default within the same cure period as provided to Thermo in the Assigned 
Agreement plus a period of ninety (90) days (thirty (30) days in the case of a 
monetary default) thereafter (or, with respect to any defaults not susceptible 
of being cured within such cure period, such longer cure period as shall be 
required to cure such default provided that Lead Agent is diligently pursuing
such cure), such cure period to commence upon such notice to Lead Agent and
Prudential, Rocky Mountain shall have all its rights and remedies with respect
to such default or right of termination as set forth in the Assigned Agreement.

        15.  No Previous Assignment. Rocky Mountain warrants and represents to 
             ----------------------
Assignee that it has not previously consented to any assignment, transfer or 
hypothecation of the Assigned Agreement, except as specified herein.

        16.  Payments to Project Control Account. Rocky Mountain hereby agrees
             -----------------------------------
that, so long as any Obligations are outstanding under the Loan Agreement, the
Notes or any document executed in connection therewith and until the same have
been terminated or satisfied in full, as the case may be, all payments to be
made by Rocky Mountain with respect to the Assigned Agreement shall be in lawful
money of the United States of America, in immediately available funds at the
location set forth in Schedule 16, directly to the Disbursement Agent designated
in and for deposit as specified in part one of Schedule 16, attached hereto, or
to such other person and/or at such other address as Lead Agent may from time to
time specify in writing to Rocky Mountain. Thermo agrees that proptly after
receipt by Thermo of a written request from Rocky Mountain, Thermo shall confirm
in writing to Rocky Mountain whether any loans, commitments or Obligations are
outstanding under the Loan Agreement, the Notes or any such documents. For

or remedy by Assignee or Lead Agent or pursuant to judicial proceedings, or (b)
Thermo rejects the Assigned Agreement under Title 11, United States Code, or
other similar Federal or state statue and such rejection is approved by the
appropriate bankruptcy court, and in either case (i) no funds payable under the

of such transfer or rejection, (ii) Lead Agent shall have arranged for the
curing of any default susceptible of being corrected by Lead Agent or by a
purchaser at any judicial or non-judicial sale, (iii) the Assigned Agreement
shall have been terminated pursuant to the terms thereof by reason of a default

States Code, or other similar Federal or state statute, and (iv) the effect upon

rectified to Rocky Mountain's reasonable satisfaction, Rocky Mountain shall,
within (15) days after receipt of written request therefor, execute and deliver
an agreement to Lead Agent or its nominee, purchaser, assignee or transferee, as
the case may be, for the remainder of the term of the Assigned Agreement, and
with the same terms as are contained therein, whereupon such agreement shall be

notifies Rocky Mountain in writing of Assignee's election to exercise its rights
hereunder. If Thermo defaults in the performance of its covenants to the Secured
Parties in, or an Event of Default shall have occurred and be continuing under, 
the Loan Agreement, Assignee shall have the right inter alia to (i) declare all 
                                                  ----------

assignee or transferee to assume all of Thermo's right, title and interest in, 
to and under the (subject to the terms of this Supplemental Agreement) Assigned 
Agreement, and (v) exercise any other remedies provided under the Loan Agreement
or otherwise available at law or in equity; subject to Assignee's compliance 
with the provisions of the Assigned Agreement and the terms of this Supplemental
Agreement. Rocky Mountain shall cooperate with Assignee in Assignee's exercise 
of such rights.

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

any direct contractual obligations to Assignee, and Assignee hereby acknowledges

connection with lending arrangements with Thermo except as provided herein and 
in the Assigned Agreement. In addition, Assignee agrees that, except as

                            SUPPLEMENTAL AGREEMENT

                           AND CONSENT TO ASSIGNMENT


     THIS SUPPLEMENTAL AGREEMENT AND CONSENT TO ASSIGNMENT ("Supplemental 
Agreement"), effective as of the 7th day of April 1993, by and between THERMO 
COGENERATION PARTNERSHIP, L.P., a Delaware limited partnership ("Thermo"), and 
ROCKY MOUNTAIN PRODUCE LIMITED LIABILITY COMPANY, a Colorado limited liability 
company ("Rocky Mountain"), and THE PRUDENTIAL INSURANCE COMPANY OF AMERICA, as 
a lender (hereinafter, together with any successors or assigns in such capacity,
referred to as "Prudential") and as lead agent (hereinafter, with any successors
and assigns in such capacity, referred to as the "Lead Agent") for the Secured 
Parties under the Construction and Term Loan Agreement dated as of April 7, 
1993, among Thermo, Prudential, and CSW Energy, Inc., and the other financial 
institutions named therein as lenders, the Lead Agent and CSW Energy, Inc., as 
Bank Agent (as amended from time to time, the "Loan Agreement").

    
                                   RECITALS:


     A.    On March 22, 1993, Rocky Mountain entered into with Thermo 
Cogeneration Partnership, a Colorado partnership, a Thermal Supply Lease 
Agreement (the "Assigned Agreement"), which Assigned Agreement contains, among 
other things, the agreement of the parties as to (i) the construction of a 
twenty (20) acre (more or less) commercial greenhouse (the "Facility") on 
certain real property (the "Land") owned by Thermo



<PAGE>
 
in Fort Lupton, Colorado, (ii) the leasing of such Land and the Facility by
Thermo to Rocky Mountain, (iii) the operation of the Facility by Rocky Mountain
for the commercial production of agriculture products, and (iv) the agreement by
Thermo to supply, and Rocky Mountain to utilize, Rocky Mountain's thermal energy
requirements for such agricultural production at the Facility from Thermo's
cogeneration plant (the "Plant") to be constructed on the site (the "Project
Site") of which the Land is part:

     B.    In order to facilitate financing and construction of the Plant and 
the Facility, Thermo Cogeneration Partnership has assigned the Assigned 
Agreement to Thermo, and Thermo, acting in the capacity of borrower, has entered
into the Loan Agreement.  Thermo has also, in accordance with the requirements 
of the Loan Agreement, collaterally assigned all of its right, title and 
interest in, to and under the Assigned Agreement to Lead Agent pursuant to the 
Collateral Assignment dated as of April 7, 1993 (the "Collateral Assignment").  
It is a condition precedent to the initial funding by Lenders under the Loan 
Agreement that Rocky Mountain execute and deliver this Supplemental Agreement.

     C.    Pursuant to that certain Project Management Agreement dated as of 
December 21, 1992 (the "Project Management Agreement") between Thermo Project 
Management, Inc., a Colorado corporation ("Project Manager"), and Thermo (as 
assignor or successor to Thermo Cogeneration Partnership), Thermo has appointed 
Project Manager as its agent to carry out and enforce the Assigned Agreement 
within the scope of Project Manager's obligations under the Project Management 
Agreement.

     D.    The Loan Agreement contains certain terms and conditions that, during
its term, will impact not only Thermo, but also Rocky Mountain as lessee and 
Facility Operator under

                                       2
<PAGE>
 
the Assigned Agreement, and will place certain restrictions and impose certain
obligation on Thermo as lessor and owner and Rocky Mountain as lessee and
operator with respect to the construction, leasing, and operation of the
Facility and the Plant; and

     E.    By entering into this Supplemental Agreement, the parties desire to 
(i) acknowledge the existence of such terms and conditions in the Loan 
Agreement, (ii) supplement the terms of the Assigned Agreement in certain 
instances in which the Loan Agreement contains additional or more detailed terms
and conditions dealing with similar subjects as dealt with in the Assigned 
Agreement, and (iii) provide in certain instances that the terms and conditions 
of this Supplemental Agreement and the Loan Agreement shall, to the extent 
specifically expressed herein, supersede and prevail over any conflicting 
provisions of the Assigned Agreement.

     NOW, THEREFORE, in consideration of the premises and the mutual promises 
and covenants contained in this Supplemental Agreement, the parties agree as 
follows:

     1.    Definitions.  Capitalized terms used herein (including in the 
           -----------
schedules attached hereto) have the meanings set forth herein, or if not 
defined herein the meanings set forth in the Assigned Agreement, and if not
defined herein or in the Assigned Agreement, in the Loan Agreement.  The Secured
Parties (as defined in the Loan Agreement) are sometimes referred to herein as 
"Assignee."

     2.    Term.  This Supplemental Agreement shall remain in full force and 
           ----
effect for the benefit of Lead Agent and the lenders under the Loan Agreement, 
and their respective successors and assigns, until the earlier of expiration or 
earlier termination of all obligations of Rocky Mountain under the Assigned 
Agreement, or until such time as all loans, commitments, and obligations 
incurred by Thermo under the Loan Agreement, the Notes, or any collateral or 
other documents

                                       3
<PAGE>
 
entered into in connection therewith (the "Obligations") have been duly paid and
performed ("Termination"); provided, however, that the provisions of section 6
of this Supplemental Agreement shall survive the expiration or complete
termination of the Assigned Agreement; and, provided further, that is the Lead
Agent or the lenders shall initiate action because of an Event of Default by
Thermo under the Loan Agreement, and as a result of such action the rights of
Thermo in the Facility, the Land, the Plant, or the Project Site shall be
terminated by foreclosure or otherwise, any assignee or any transferee of the
rights of Thermo in the Facility, the Land, the Plant, or the Project Site shall
also be entitled to enjoy the benefits of, and to exercise the rights conferred
on, the Lead Agent and the lenders under such section 6. From and after the time
of Termination, the matters covered by this Supplemental Agreement shall be
governed solely as provided in the Assigned Agreement, as the same may have been
amended in the interim, and this Supplemental Agreement shall automatically
become null and void and be of no further force and effect, except as is
otherwise, provided in the preceding sentence. Any extension of time for payment
or performance of the Obligations, whether by amendment, modification or
supplementation of the Loan Agreement or otherwise, shall extend the time for
Termination. After Termination, neither the prior effectiveness of this
Supplemental Agreement nor the text of any provision herein which does not
expressly survive such termination shall have any effect whatsoever on the
construction or interpretation of the Assigned Agreement.

     3.    Representations and Warranties.  Rocky Mountain hereby represents and
           ------------------------------
warrants to Thermo and to Prudential as follows:

               (b)  Rocky Mountain has the power, authority and legal right to 
execute, deliver and perform the Assigned Agreement and this Supplemental 
Agreement, and the execution and delivery by Rocky Mountain of the Assigned
Agreement and this Supplemental Agreement and the performance of its obligations

do not and will not (i) require any consent or approval of any member of Rocky
Mountain except for those approvals which have been duly obtained and are in

or imposition of any lien, security interest, charge or encumbrance upon or with
respect to any of the properties now owned or hereafter acquired by Rocky
Mountain. The members of Rocky Mountain have approved the Assigned Agreement
and, consequently, the condition referred to in paragraph 21.3 of the Assigned
Agreement has been satisfied.

               (c)  Each of the Assigned Agreement and this Supplemental 
Agreement has been duly executed and delivered and constitutes a valid and 
binding obligation of Rocky Mountain, enforceable against Rocky Mountain in 
accordance with its terms, except as the enforceability thereof may be limited 
by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting 
creditors' rights generally.

Assigned Agreement or this Supplemental Agreement or the performance by Rocky 
Mountain of its obligations hereunder or thereunder. Rocky Mountain has obtained
all permits, licenses, approvals, consents and exemptions with respect to the 
performance of its obligations under the Assigned Agreement and this 
Supplemental Agreement required by applicable laws, statutes, rules and 
regulations in effect as of the date hereof.

               (e)  Rocky Mountain is not in default with respect to the

any claims or rights of set-off by Rocky Mountain or by any of its affiliates or
parent against Thermo.

               (f)  There are no proceedings pending or, to the best of Rocky 
Mountain's knowledge after due inquiry, threatened against or affecting Rocky 
Mountain in any court or before any governmental authority or arbitration board 
or tribunal (whether or not purportedly on behalf of Rocky Mountain) which may 
result in a material adverse effect upon the property, business, prospects, 
profits or condition (financial or otherwise) of Rocky Mountain, or the ability 
of Rocky Mountain to perform its obligations under the Assigned Agreement or 
this Supplemental Agreement; and Rocky Mountain is not in default with respect 
to any order of any court, governmental authority or arbitration board or 
tribunal.

any action or inaction of Rocky Mountain or any of its Affiliates. Any such Lien

     4.    Option to Purchase Suspended.  Anything in the Assigned Agreement to

Land) at any time there remains unpaid any indebtedness under the Loan Agreement
unless, at the time of such exercise, Thermo shall have obtained Prudential's 
approval (which approval may be withheld in Prudential's sole discretion) of 
alternative thermal use arrangements, including all appropriate regulatory and 
administrative approvals and filings, for thermal energy produced by the Plant.

Purchase Price," determined in the manner provided in paragraph 5.2 of the
Assigned Agreement, plus such additional sum as may be payable pursuant to
paragraph 5.5 of the Assigned Agreement should Rocky Mountain also purchase the
Land as provided in such paragraph. At the closing of such sale, Thermo shall
obtain from Lead Agent and deliver to Rocky Mountain a Release by Lead Agent
from the lien of any mortgage(s), deeds of trust, and other security agreements
encumbering the Facility (and the Land if purchased) to secure repayment of the
indebtedness of Thermo under the Loan Agreement and Rocky Mountain shall deliver
to Thermo and Lead Agent a ratification and reaffirmation of all thermal supply
provisions of the Assigned Agreement in such form as Thermo or Lead Agent may
reasonably request. Nothing herein all be construed to relieve Rocky Mountain of
its obligations under paragraph 5.8 of the Thermal Supply Agreement. Under no
circumstances shall Rocky Mountain be entitled to exercise the Purchase Option
at any time while Thermo is in default under the Assigned Agreement or this
Supplemental Agreement or while an Event of Default is continuing under the Loan
Agreement. Should the lenders, the Lead Agent or their nominee exercise any
remedies arising because of an Event of Default by Thermo under the Loan
Agreement whereby Thermo's rights in the Facility, the Land, the Plant or the
Project Site shall be terminated, assumed, or transferred, the Purchase Option,
effective as of the time of such exercise, shall permanently lapse and become
void and shall no longer be binding upon Thermo, the Lead Agent, any lender
under the Loan Agreement or any transferee of the Facility, the Land, the Plant
or the Project Site in connection with such exercise of rights or remedies
because of such Event of Default.

               -------------------------------------------
Assigned Agreement notwithstanding, Rocky Mountain shall not claim prevention of
or interference with performance of its obligations pursuant to the Assigned 
Agreement or the suspension or termination of its obligations under the Assigned
Agreement as the result of any default of Thermo without first giving a copy of 
any notice of default or termination to Lead Agent, such notice to be coupled 
with a request to Lead Agent to cure any defaults which are susceptible of being
corrected by Lead Agent, within a cure period as provided to Thermo in the 
Assigned Agreement plus a period of ninety (90) days (thirty (30) days in the 
case of a monetary default) thereafter (or, with respect to any defaults not 
susceptible of being cured within such cure period, such longer cure period as 
shall be required to cure such default provided that Lead Agent is diligently 
pursuing such cure), such cure period to 


                                      17
<PAGE>

or other courier, (b) when transmitted by telecopy to the number specified
below, or (c) when received, if deposited in a regularly maintained receptacle
for the United States Postal Service, postage prepaid, registered or certified
mail, return receipt requested, addressed to Lead Agent and Prudential at the

(facsimile) numbers provided below are for the convenience of Rocky Mountain
only. Transmission by telecopy shall constitute provision of notice under this
Supplemental Agreement only if receipt thereof is acknowledged in writing by
Prudential or Lead Agent, as the case may be, within such period. The address
for notices to Prudential and Lead Agent is as follows:

such performance until the lapse of the notice and the applicable cure periods
or extension periods. Lead Agent may, but shall be under no obligation to, make

Thermo, with the same effect as

                                      18
<PAGE>
 
if made or performed by Thermo. If Lead Agent or Prudential fails to cure a
default within the same cure period as provided to Thermo in the Assigned
Agreement plus a period of ninety (90) days (thirty (30) days in the case of a
monetary default) thereafter (or, with respect to any defaults not susceptible
of being cured within such cure period, such longer cure period as shall be
required to cure such default provided that Lead Agent is diligently pursuing
such cure), such cure period to commence upon such notice to Lead Agent and
Prudential, Rocky Mountain shall have all its rights and remedies with respect
to such default or right of termination as set forth in the Assigned Agreement.

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

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

money of the United States of America, in immediately available funds at the 
location set forth in Schedule 16, directly to the Disbursement Agent designated
in and for deposit as specified in part one of Schedule 16, attached hereto, or 
to such other person and/or at such other address as Lead Agent may from time to
time specify in writing to Rocky Mountain.  Thermo agrees that promptly after 
receipt by Thermo of a written request from Rocky Mountain, Thermo shall confirm
in writing to Rocky Mountain whether any loans, commitments or Obligations are 
outstanding under the Loan Agreement, the Notes or any such documents.  For

rectified to Rocky Mountain's reasonable satisfaction, Rocky Mountain shall,
within fifteen (15) days after receipt of written request therefor, execute and
deliver an agreement to Lead Agent or its nominee, purchaser, assignee or
transferee, as the case may be, for the remainder of the term of the Assigned
Agreement, and with the same terms as are contained therein, whereupon such

the Loan Agreement, Assignee shall have the right, inter alia, to (i) declare

otherwise available at law or in equity; subject to Assignee's compliance with

     4.   Term. The initial Term of this Lease is 60 years, beginning May 15, 
          ----                                    --                  ------
1998 the "Initial Term"). The "Term" of this Lease includes the Initial Term
- ----
and any renewal or extension of the Initial Term that may be later agreed upon
in writing by the Tenant and the Landlord.

     5.   Rent. Instead of monetary rent, the Tenant will strictly perform
          ----
during the Term promptly, punctually and without notice, all of the obligations
of the Tenant as provided in this Lease. The prospect of the opportunity for
employment of an augmented workforce in the City by the Tenant is a substantial
and material inducement to the Landlord to enter into this Lease, and the
performance by the Tenant of the Employment Standard (defined below) will be
measured by good faith and fair dealing and is a very substantial part of the
consideration to Landlord for entering into this Lease (the "Rent"). The Tenant
will specifically construct and operate a greenhouse operation on the Land, and
will meet the following Employment Standard at all times during the Term:

          A.  Employees who meet the Employment Standard will be full



                                      -3-
<PAGE>
 
time employees working not less than 35 hours a week at the greenhouse or any
packing house constructed on the Land, and working or anticipated to be working
at least 48 weeks of the calendar year in permanent or long-term positions
("Qualified Employees"). Qualified Employees who meet the Employment Standard
will include persons to whom the Tenant has outsourced certain tasks, provided
those persons are occupied full-time in permanent or long-term positions in the
business of the Tenant at the Land, and receive pay and benefits substantially
similar to those employees of the Tenant performing similar functions, but will
not include vendors, merchants, or providers of intermittent labor through
contracts. Employees employed by the Tenant on management, administrative or
supervisory duties primarily directed toward the greenhouse operation located at
the Land and working at the Land not less than 35 hours a week on those duties,
at least 48 weeks of the calendar year, will be "Qualified Employees."

          B.  During the first 12 months of the Term, the Tenant will have no
obligation to have Qualified Employees or to meet any Employment Standard.

          C.  During the next 48 months of the Term (through the end of year
five of the Term) Tenant will have the following Employment Standard: Tenant
will have employees working not less than a cumulative total of 2,400 hours per
week, 52 weeks a year, on an average basis calculated every six months beginning
with the six-month period that commences on the date Tenant begins commercial
greenhouse operations, and at all times (other than as permitted under Paragraph
4.E) during such 42-month period Tenant will employ not less than 50 Qualified
Employees.

          D.  During the remaining months of the Term (all months after the
sixtieth month) the Tenant will have the following Employment Standard: Tenant
will have employees working not less than a cumulative total of 4,400 hours per
week, 52 weeks a year, on an average basis calculated every six months beginning
with the first day of the 60th month of the Term, and at all times (other than
as permitted under Paragraph 4.E) after such 60th month Tenant will employ not
less than 100 Qualified Employees.

          E.  After the first eighteen months of the Term, the Tenant may
furlough employees for up to eight weeks every other year without being in
violation of the Employment Standard. During the Term, the Tenant will have a
one-time option to suspend operations and furlough or terminate employees at the
Land for up to eight months, provided the Tenant's decision to do so is in
compliance with all other laws and regulations, the Tenant gives the Landlord
written notice at least six months before starting the suspension, and, before
the suspension, the Tenant is current and remains current on


                                      -4-
<PAGE>
 
all required payments to the State of New Mexico Employment Security Division
for payment of the Tenant's unemployment compensation obligations.

          The Tenant will pay and perform the Rent, including meeting the
Employment Standard to the Landlord on an absolutely net basis, free of any
charges, assessments, impositions or deductions of any kind, and without
abatement, deduction or set-off. Tenant will provide true and accurate monthly
reports to Landlord showing the total number of employees, and the total hours
worked by each employee. Qualified Employees will be identified by Tenant on the
reports provided to Landlord. The Landlord may examine such other employment or
accounting records of the Tenant as the Landlord deems necessary to determine or
confirm that the Tenant is in fact in compliance with the Employment Standard.
The Landlord will give the Tenant reasonable written notice before an
examination and will conduct the examination during reasonable business hours.
The Tenant consents to a release to the Landlord of records provided to state or
federal agencies or divisions to the extent those records relate to or evidence
the number of employees employed or maintained by the Tenant at the Land. The
Landlord is not and will not be construed or held to be a partner, joint
venturer or associate of the Tenant in the conduct of the business of the
Tenant. The Landlord will not be liable for any debts incurred by the Tenant in
the conduct of the business of the Tenant. The relationship between the Landlord
and the Tenant is, and will remain, solely that of landlord and tenant.

     6.   Project Participation Agreement. This Lease will serve as a Project 
          -------------------------------

will evaluate the performance of the Tenant as provided in this Lease on an
annual basis. If the Landlord determines that the performance of the Tenant as
provided in the Lease is unsatisfactory as evidenced by an Event of Default as
defined in Section 16 of this Lease, the Landlord may take steps the Landlord
deems appropriate pursuant to the rights of the Landlord as provided in this
Lease.

          G.  Sunset. Section 10(A)(7) of the Plan requires the lease to 
              ------

the project. The Landlord will retain an interest in the project and will
continue oversight of the project until the end or any earlier termination of
this Lease.

     7.   Taxes and Charges.
          -----------------

          A.  The Tenant will pay before delinquency all ad valorem property
taxes and all personal property taxes levied or assessed against the Premises by
any governmental authority (the "Taxes") although the Landlord will not be
liable for the Taxes on the Land. The Tenant will not claim exemption from the
imposition of Taxes on any Buildings (as defined below) because the Landlord
owns the Land. Both parties anticipate that there will be no Taxes imposed on
the Land, but should Taxes be imposed on Tenant's Leasehold Estate, Tenant will
promptly pay the Taxes, but may thereafter contest the imposition of the Taxes
as provided below.

          B.  The Tenant will pay before delinquency all charges for Water
(subject to the terms of attached Exhibit A-1), electricity, gas, telephone,
                                  ------------                            
sewer, rubbish and garbage removal, cable television and all other charges with
respect to the Premises.

          C.  The Tenant will furnish to the Landlord, within 30 days before the
date when Taxes become delinquent, official receipts or other evidence from the
taxing authority satisfactory to the Landlord evidencing the payment of the
Taxes.

          D.  The Tenant may seek a reduction in the tax valuation of the
Premises, and may contest in good faith by appropriate proceedings the amount or
validity of any Taxes (the "Contested Taxes"), and a deferment of payment of the
Taxes, if the Tenant first pays the Contested Taxes.

          E.  The Landlord will not be required by the Tenant to join in any
action of the Tenant with respect to Taxes. If the provisions of any law, rule
or regulation require that an action proposed by the Tenant be brought by or in
the name of the Landlord as owner of the fee of the Land, or that the owner of
the fee of the Land be joined in the action, the Tenant may request in writing
that the Landlord join in the action or permit the



                                      -7-
<PAGE>
 
action to be brought in the name of the Landlord, and the Landlord will
cooperate subject to such reasonable conditions as the Landlord might impose to
insure that the protections of the following sentence are satisfied. The
Landlord will not be liable for payment of any costs or expenses with respect to
the action brought by the Tenant, and the Tenant will indemnify, hold harmless
and defend the Landlord from any costs and expenses with respect to the action
including reasonable fees of lawyers and expenses of any action.

     8. Use.
        ---
        A.  The Premises may be used only for a greenhouse operation (including
construction, handling, sorting, picking, packing and other processing
activities), and associated office and storage space, in compliance with all
Governmental Rules, and for no other purpose (the "Permitted Use").

        B.  The Tenant will:

            (1) conduct the business of the Tenant in the Premises under the
trade name of the Tenant;

            (2) not use, or permit the use of any sound broadcasting or
amplifying device which can be heard outside or beyond the Premises;

            (3) not use, or permit the use of, any portion of the Premises as
living quarters, sleeping apartments or lodging rooms except as required to
conduct the Permitted Use;

            (4) not perform any act or carry on any practice which may damage
the Premises or the Buildings, cause any offensive odors or loud noises, or
constitute a nuisance or a menace;

            (5) at all times, continuously and uninterruptedly (i) use, occupy,
and operate the Premises for the Permitted Use, (ii) use any storage and office
space only with respect to the Permitted Use, and (iii) open and keep open the
Premises for operation as a greenhouse with adherence to the Employment
Standard.

            (6) not use any portion of the Premises for services except as
customary for the business and operations of the Tenant with respect to the
Permitted Use;

            (7) keep the Premises free of pests or vermin by periodic pest
control treatment;

            (8) comply with all governmental laws, rules, and regulations
applicable to the Permitted Use and obtain and maintain in force all
governmental permits and licenses necessary for the lawful conduct of the
business of the



                                      -8-
<PAGE>
 
Tenant.

            (9) not suffer, permit or cause any waste to occur within the
Premises, and will not cause or permit any Hazardous Material to be brought
upon, kept or used in or about the Premises, except such as are normally used in
the operation of a greenhouse, and in strict compliance with all laws,
ordinances or regulations. As used in this Lease, the term "Hazardous Material"
is defined as any hazardous or toxic substance, material or waste that is now or
becomes regulated or restricted by any local governmental authority, New Mexico,
or the United States Government. The term "Hazardous Material" includes, without
limitation, any petroleum products or by-products, asbestos (in any form),
chemicals, gases or any other material or substance that upon exposure or
ingestion may reasonably be anticipated to pose a hazard to the health or safety
of the anticipated occupants of, or visitors to the Premises. If the Tenant, in
the normal course of operation of the business of the Tenant in the Premises, as
stated in this Section, is required to use certain substances that may be
considered Hazardous Material as provided in this Lease, the Tenant may, in such
event and despite the foregoing provisions, use the substances in the business
operations of the Tenant provided, however, the Tenant will be solely
responsible for the proper use and disposal of the substances in accordance with
all applicable laws and Tenant will indemnify the Landlord and the Premises with
respect to the use and disposal of the substances (both during and after the
term of this Lease) and will permit the Landlord to conduct inspections of the
Premises at reasonable times to confirm that the Tenant is in compliance with
all laws, ordinances or regulations. A list of Hazardous Materials that the
Tenant proposes to use in the business operations of the Tenant is attached as
Exhibit E.
- ----------

            C.  The provisions of subparagraph B. of paragraph 8 of this Lease
are a material part of the consideration which induced the Landlord to sign this
Lease with the Tenant.

            D.  If the Tenant breaches any provision of this paragraph 8 of this
Lease more than once during any calendar year, the Landlord may, instead of
exercising any other remedies available to the Landlord for each breach, give
notice to the Tenant of a breach, and, if the Tenant fails to cure the breach
within 10 days, elect to receive from the Tenant liquidated damages of 500
dollars a day for each calendar day during which a breach occurs and continues.
The failure of the Tenant to operate the Premises in adherence with paragraph 8
of this Lease will cause great harm to the Landlord and the Buildings. To
specify or determine exactly the amount of damages resulting to the




                                      -9-
<PAGE>
 
Landlord and the Buildings from the failure of the Tenant to operate the
Premises as provided in this paragraph of the Lease is difficult. The daily
liquidated damages provided for in this paragraph of the lease is a reasonable
amount and bears a rational relationship to the damages that the Landlord could
suffer. The Landlord also will be entitled to terminate this Lease as provided
in paragraph 16 of this Lease in addition to receiving liquidated damages. The
Tenant will pay the liquidated damages to the Landlord within 5 days of demand
for payment as provided in this Lease, and failure to timely pay the liquidated
damages to the Landlord will constitute a breach of this Lease without further
notice.

            9.  Maintenance and Repair. The Tenant will maintain the Premises in
                ----------------------                                        
a clean, orderly, sanitary, and safe condition, in good repair and in compliance
with all Governmental Rules. The standard of repair will be at least equal the
condition of the repaired item immediately before the event which created the
circumstance requiring the repairs to be made. The Tenant will give notice to
the Landlord of any material alterations or additions by the Tenant to the
Buildings. The Tenant will comply with all Governmental Rules enforced from time
to time which require repairs, replacements or alterations to be made to the
Buildings and with respect to any improvements constructed by the Tenant on the
Land.

            10.  New Construction.
                 -----------------

                 A.  As set forth in subparagraph 6.D, the Tenant will start
construction of a new building or buildings and other improvements and fixtures
on the Land as provided on attached Exhibit B (collectively, the "Buildings")
                                    ---------
and will use the best and diligent good faith continuous efforts of Tenant to
complete the construction, and, upon completion of construction, will possess
and occupy and start the conduct of the business of the Tenant as soon as
reasonably practicable. "Buildings" includes any additions, replacements, and
fixtures that may be later constructed or installed on the Land or the Premises
when the context of this Lease allows. The Buildings will be constructed in a
good and worker-like manner in accordance with (i) all requirements of City and
County ordinances, (ii) all applicable rules, regulations and requirements of
all departments, boards, bureaus, officials and authorities having jurisdiction
of the construction of the Buildings, and (iii) the requirements of the City and
County fire insurance ratings. All necessary permits for the Buildings will be
obtained by the Tenant. The Tenant will deliver to the Landlord for approval by
the Landlord before any construction is started copies of all final plans,
specifications and vertical elevations which will be prepared as if for
architectural



                                     -10-
<PAGE>
 
review, for the Buildings (the "Plans").

            B.  The Tenant will not permit any mechanics' lien or other liens
(collectively, the "Liens") to be recorded against the Premises before, during
or after the Term. If Liens are recorded against the Premises, the Tenant will
cause the Liens to be discharged of record by payment, deposit, bond, order of
court, or otherwise, within 30 days after the Tenant has received actual notice
of any Lien which is filed in the records of the County.

            C.  The Tenant will provide a notice to the Landlord as provided in
paragraph 23 of this Lease (the "Notice") of any construction, grading,
installation, or improvements on the Land (the "Work") no later than 10 days
before the start of the Work. The Tenant will post on the Premises, as provided
by New Mexico law, two "Notices of the Landlord's Non-Responsibility" before
starting any Work (the "Non-Responsibility Notices"), and will maintain the Non-
responsibility Notices on the Premises until all costs of the Work, including
all costs of architectural, surveying, and engineering fees, and all other
liabilities for which Liens could be recorded as provided by the statutes of New
Mexico, are fully paid and satisfied. The Landlord may post the Non-
responsibility Notices if the Tenant fails to post the Non-responsibility
Notices.

            D.  If Liens are recorded against the Premises and not discharged
within thirty days after the Lien is filed in the County records as provided in
subparagraph B above and the Tenant has received at least 90 days actual notice
of the Liens, the Landlord may pay the Liens after reasonable inquiry as to the
validity of the Liens. Any amounts so paid, including the fees of lawyers and
title companies, expenses and interest, will be additional Rent due from the
Tenant to the Landlord, and will be paid to the Landlord with interest at the
rate of eighteen percent a year within five days after a Notice from the
Landlord to the Tenant of a bill for the amount is given. The Tenant will
indemnify the Landlord against all costs and charges, including lawyer fees,
reasonably incurred in the defense of any action to discharge the Premises from
Liens. The Tenant may contest Liens in good faith, with due diligence, if the
Liens are discharged of record while contests are pending.

            E.  Before starting the Work, the Tenant will obtain public
liability, builder's risk and other insurance as provided in this Lease, and
will maintain the insurance in full force and effect during the course of
construction.

            F.  Before starting the Work, the Tenant will obtain and deliver to
the Landlord waivers of lien from any surveyor, architect or engineer that has
performed



                                     -11-
<PAGE>
 
any pre-grading construction or installation Work with respect to the Premises.

            G.  Ownership of the Buildings (including fixtures) will remain in
the Tenant during the Term or until any earlier termination of this Lease,
subject to the rights of any Leasehold Mortgagee, and the requirements of this
Lease. At the end of the Term or any earlier termination of this Lease, the
Tenant will perform the Departure Obligation, as defined in paragraph 1(C). If,
pursuant to the Departure Obligation, the Tenant elects to assume and perform
the Reclamation Obligation, title to and ownership of all the buildings,
personal property and trade assets will remain the property of the Tenant and
may be removed from the Premises if removed within 180 days after the end of the
Term or earlier termination of this Lease; provided, however, the Tenant will
pay the Landlord $10,000 per month as monetary additional Rent for each month
after the end of the Term or earlier termination of this Lease in which the
property is not removed. If, pursuant to the Departure Obligation, the Tenant
elects to assume and perform the Buildings Transfer Obligation, title and
ownership to the Buildings, including the boilers and piping (including effluent
piping), will automatically vest in the Landlord free and clear of any liens or
encumbrances without signing of any further instrument and without any payment
by the Landlord. The Tenant will, on demand by the Landlord, sign and
acknowledge any further assurance of title and ownership to the Buildings as the
Landlord may request. The Buildings and all personal property and trade assets,
and fixtures will remain subject to the liens provided in this Lease in favor of
the Landlord. As security for the payment and performance of the Rent or other
obligations required to be paid or performed by this Lease by the Tenant, the
Tenant grants to the Landlord a lien upon the Buildings, all personal property
and trade assets of the Tenant now or later located upon the Premises. Subject
to the provisions of Paragraphs 16 and 20, if the Tenant abandons or vacates any
substantial portion of the Premises or is in default of the payment or
performance of the Rent, or other obligations required to be paid or performed
by this Lease, the Landlord may enter upon the Premises, by force if necessary,
and take possession of all or part of the Buildings, personal property and
trade assets, and may sell all or part of the Buildings, personal property and
trade assets at public or private sale, in one or successive sales, with or
without notice, to the highest bidder for cash and on behalf of the Tenant, sell
and convey all or part to the bidder, delivering to the bidder all of the title
and interest of the Tenant in the Buildings, personal property and trade assets
sold to the bidder. The proceeds of the sale will be applied by the Landlord
toward the cost of the sale and then toward the payment of all sums then due by
the Tenant to the Landlord



                                     -12-
<PAGE>
 
as provided in this Lease. The statutory lien of the Landlord for Rent is not
waived. The express contractual lien granted in this Lease is in addition to the
statutory lien. This Lease is intended as, and constitutes a security agreement
within the meaning of the New Mexico Uniform Commercial Code and, the Landlord,
in addition to the rights of the Landlord as provided in this Lease, will have
all of the rights, titles, liens and interests in the property of the Tenant
now or later located upon the Premises that are granted a secured party, as that
term is defined under the New Mexico Uniform Commercial Code, to secure the
payment to the Landlord of the Rent and obligations of the Tenant provided in
this Lease and in compliance with this Lease. Tenant will execute a financing
statement in favor of Landlord. At the request of the Tenant, the Landlord will
subordinate any lien and the rights and remedies of the Landlord to enforce any
such lien granted to the Landlord by law or by this Lease to the first lien of a
Leasehold Mortgage as to the Buildings and to any purchase money lender as to
any personal property and trade assets, subject to the Landlord's right to
reasonably approve the form and substance of any requested subordination.

            10.  The Tenant will deliver to the Landlord within a reasonable
period of time after the completion of the Work but not over 30 days, an actual
field survey (the "Survey") of the perimeter boundary of the Land and any
related easement property containing a plat or map showing all buildings and
related improvements (if any). The Survey will (i) state that the Survey is
prepared for the Landlord, the Tenant and any title insurer selected by the
Tenant if the Tenant wants to obtain a lessee's policy of title insurance at the
sole cost and expense of the Tenant, (ii) contain a narrative legal description
and the courses and distances legal description of the Land and any related
easement property, (iii) be certified as of a date then current by a land
surveyor licensed in New Mexico acceptable to the Landlord, and (iv) show the
items listed on Exhibit C. Upon the completion of the construction and fixturing
Work of the Tenant of and within the Premises, (1) the Tenant will deliver to
the Landlord a copy of a properly executed certificate of occupancy from all
governmental entities having jurisdiction, (2) furnish the Landlord with a
complete set of reproducible "as-built" drawings, including "as-built" for all
underground utilities and piping (including effluent piping), and (5) copies of
lien waivers from all parties performing labor or supplying equipment and
materials with respect to the Work of the Tenant.

           11.  Insurance Terms.
                ----------------
                A.  The Tenant will provide and maintain during the Term, for
the



                                     -13-

<PAGE>
 
mutual benefit of the Landlord and the Tenant, fire and extended coverage
insurance with respect to the Buildings. The insurance protection will be
against fire and the other risks are covered by the standard form of extended
coverage insurance generally available from time to time in the City (the "Fire
Insurance"). The Fire Insurance will include in the coverage, loss or damage in
aggregate amounts not less than one hundred percent of the full replacement cost
of the Buildings, foundations excluded, and will be underwritten by an insurance
company acceptable to the Landlord. The Tenant will provide and maintain a steam
boiler, air conditioning equipment, pressure vessels or similar apparatus, and
machinery insurance (the "Boiler Insurance"). The Tenant will furnish the
Landlord a certificate of insurance evidencing the Fire Insurance and the Boiler
Insurance (collectively, the "Insurance") coverages and will furnish the
Landlord a copy of all policies of insurance. During the Term, the Landlord will
be entitled to any insurance in an amount sufficient to avoid being a co-
insurer. While the Buildings are under construction, the Insurance will be
carried by the Tenant in builder's risk form, which will be reviewed and
approved by the Landlord. The insurance policy will name the Tenant and the
Landlord as their interests may appear.

            B.  During the Term, the Tenant will provide and maintain at all
times broad form comprehensive general public liability insurance, and elevator
insurance (if applicable), as appropriate (the "Comprehensive Insurance"), that
names the Landlord as an additional insured, protecting both the Landlord and
the Tenant against claims of all persons, firms and corporations for personal
injury, death and property damage, with minimum limits of liability with respect
to personal injury of five million dollars for each occurrence, one million
dollars for each individual, and, in connection with property damage, a broad
form policy with minimum limits of five hundred thousand dollars for each
occurrence, or higher coverage as may be required by law, to protect the
Landlord from liability as provided in the New Mexico Tort Claims Act, or any
comparable future statute, or otherwise.

            C.  The Tenant will provide and maintain for the mutual benefit of
the Landlord and the Tenant any other insurance, in amounts required by the
Landlord, in the reasonable discretion of the Landlord and consistent with
ordinary business practices, against any other insurable hazards insured against
with respect to commercial real estate.

            D.  All policies of insurance obtained by the Tenant as provided in
this Lease (the "Policies") will be obtained from insurance companies qualified
to do business within New Mexico that have an S&P rating of A+ or better (or
comparable



                                     -14-
<PAGE>
 
ratings if S&P ratings are modified or discontinued). If this lease is ever
allowably assigned by the Tenant, any new insurance companies and the Policies
will also be subject to the approval of the Landlord. All Policies will include
a waiver of subrogation by the insurance company. All Policies will provide for
30 days Notice to the Landlord before cancellation. Before the effective date of
this Lease, the Tenant will deliver to the Landlord certificates of insurance
evidencing all required Policies. At least 30 days before the expiration date of
any Policies, the Tenant will deliver to the Landlord, certificates of insurance
evidencing renewal. All Policies will provide that no act or omission by the
Tenant will impair or affect the rights of the Landlord to receive and collect
the Insurance proceeds, and that the coverage provided by the Policies will not
be affected by the performance of any Work in or about the Premises.

            E.  Nothing in this Lease will prevent the Tenant from acquiring and
maintaining insurance of the kind in the amounts as provided in this paragraph
under a blanket insurance policy or policies (collectively, the "Blanket
Policy") which includes other properties as well as the Premises if the Blanket
Policy (i) will specify in the policy the amount of the total insurance
allocated to the Premises that will not be less than the amounts required by
this Lease, (ii) the amounts specified will be sufficient to prevent any one of
the assureds from becoming a co-insurer, and (iii) the Blanket Policy will
comply as to endorsements and coverage with the terms of this Lease.

            F.  If the Tenant fails to obtain or fails to maintain any insurance
required by this Lease, the Landlord may procure the insurance and the Tenant
will reimburse the Landlord for all expenses incurred by the Landlord.

            G.  If any Building is destroyed or damaged in whole or in part by
fire or other casualty (the "Occurrence"), this Lease will continue in full
force and effect and the Rent and other obligations payable or to be performed
by the Tenant as provided in this Lease will not abate or be reduced because of
an Occurrence except as provided in Paragraph 11.H.

                (1) Subject to the terms of any Leasehold Mortgage: all
insurance policies with respect to damage to or destruction of the Buildings
will provide that any Insurance proceeds to be paid will be adjusted solely by
the Landlord and the Tenant, as their interests may appear. The net proceeds, if
less than $200,000, will be paid to the Tenant. The net proceeds, if over
$200,000, will be handled as follows, at the option of Tenant:

                      (a)  The proceeds may be paid to and deposited with


                                     -15-
<PAGE>
 
a bank jointly selected by the Landlord, the Tenant, and any Leasehold
Mortgagee, as insurance trustee (the "Insurance Trustee"), that will hold, apply
and make the proceeds available as provided in this Lease; or

            (b)  The Tenant will furnish a bond or letter of credit for the
benefit of Landlord, in a form satisfactory to Landlord in the amount of the
Insurance proceeds, or such lesser amount as set forth below, and upon receipt
by Landlord of such bond or letter of credit the insurance proceeds will be
released to Tenant. Five days prior to the time that Tenant makes its election
regarding handling of the Insurance proceeds, Tenant will notify Landlord in
writing whether Tenant has elected the Reconstruction Obligation or the
Reclamation Obligation. If Tenant elects the Reconstruction Obligation, Tenant
will proceed to restore the Buildings to at least the reasonable equivalent of
the previous condition of the Buildings. If applicable, either the Insurance
Trustee will make the proceeds available upon completion of and payment for the
Reconstruction or Reclamation Obligation, or, upon satisfactory completion of
and payment for completion of the Reconstruction or Reclamation Obligation, the
bond or letter of credit will be canceled. If Tenant elects the Reclamation
Obligation, then Tenant will, within 30 days thereafter, provide Landlord with
a written plan for completion of the Reclamation Obligation, including a
reasonable engineer's estimate of probable cost. When the Landlord has indicated
in writing that the Landlord approves the reclamation plan and approves the
engineer's estimate of estimated cost, 125% of the probable cost of reclamation
will be retained by the Insurance Trustee from the Insurance proceeds (or the
letter of credit or bond need only be in that amount), and the Tenant will
proceed to complete the Reclamation Obligation within 180 days of the date of
election of the Reclamation Obligation using the Insurance proceeds to do so.
The remainder of the Insurance proceeds may be released to Tenant and any
Leasehold Mortgagee. If the Tenant elects the Reclamation Obligation, provided
all other obligations of Tenant as provided in this Lease are satisfied,
Landlord will have no other claim on the Insurance proceeds, and the Lease will
terminate upon completion of the Reclamation Obligation.

            (2)  The Tenant will give prompt notice of any Occurrence to the
Landlord if the damage or loss is or may be over $50,000, and the Tenant,
regardless of the dollar amount of an Occurrence, will promptly repair, replace
and rebuild the Buildings to the extent of the value and as nearly as
practicable to the character of the Buildings existing immediately before the
Occurrence. If the Occurrence is over $200,000, as provided in paragraph 11
(G)(1) above, the Tenant will elect either the Reconstruction or



                                     -16-
<PAGE>
 
Reclamation Obligation, and will thereafter proceed as follows:

            (a)  Before starting any reconstruction or reclamation work (the
"Insurance Work"), Plans will be filed with and approved by all City and other
governmental authorities having jurisdiction of the Insurance Work (the
"Governmental Approvals"), and a fixed fee estimate for all costs of the
Insurance Work will be obtained by the Tenant and furnished to the Landlord.

            (b)  Before starting any Insurance Work, the Tenant will deliver to
the Landlord a certificate of insurance evidencing a Comprehensive Insurance
policy as provided in this Lease and a Builder's Risk insurance policy covering
the Work.

            (c)  The Insurance Work will start within 90 days after settlement
is made with the Insurance companies and the Insurance proceeds are paid to the
Insurance Trustee or the Tenant, as provided in this Lease, and the Governmental
Approvals are obtained. The Reconstruction Obligation will be completed within a
reasonable time, free and clear of all liens and encumbrances, except any
Leasehold Mortgage, as provided in the Plans. The Reclamation Obligation will be
completed within 180 days, free and clear of all liens and encumbrances, and the
lien of the Leasehold Mortgagee will be fully released. The Reclamation
Obligation will be completed as provided in the Plans.

            (d)  At least 10 days before starting the Reclamation or
Reconstruction Obligation, the Tenant will notify the Landlord if increased
Insurance premiums will be charged, and the Tenant will pay the increased
premiums, if any, charged by the Insurance companies carrying Insurance on the
Buildings to cover the additional risk during the course of the Insurance Work.

            (e)  The Insurance Trustee or the Tenant, as the case may be, will
apply the net proceeds of any Insurance to the payment of the cost of the
reconstruction or reclamation Insurance Work, as the Insurance Work progresses.
If the net proceeds are held by an Insurance Trustee (1) payments will be made
against properly certified vouchers of a competent architect and general
contractor in charge of the Insurance Work that are selected by the Tenant and
(2) the Insurance Trustee will advance out of the Insurance proceeds toward each
payment, to be made by or on behalf of the Tenant, an amount that bears the same
proportion to the payment as the whole amount received by the Insurance Trustee
bears to the total estimated cost of the Insurance Work, except that the
Insurance Trustee will withhold 10 percent from each amount paid until the
Insurance Work is completed, and proof is furnished that no lien or liability
has attached or



                                     -17-
<PAGE>
 
will attach to the Premises with respect to the Insurance Work. If the total
estimated cost of the Insurance Work is over the amount of the net Insurance
proceeds received by the Insurance Trustee, the Insurance Trustee will require
the Tenant, before the Insurance Work is started, to secure the Insurance
Trustee by surety bond, letter of credit or cash deposit equal to the amount of
the excess of the estimated cost over the net Insurance proceeds as security for
the due completion, within a reasonable time, subject to force majeure, of the
Insurance Work, and the cash deposit will be deemed to be part of the net
Insurance proceeds for the purpose of this paragraph. If the Insurance proceeds
exceed the cost of the Insurance Work, the balance remaining after payment of
the cost of the Insurance Work will be paid over and belong to the Tenant.

            H.  This Lease will not terminate (unless Tenant elects and properly
completes the Reclamation Obligation) or be affected in any manner because of
the Occurrence, or because of the untenantability of the Premises or of the
Buildings, and the Tenant will pay or perform the Rent and all other obligations
as provided in this Lease without abatement or reduction, except that Tenant
will be relieved of the "continuous operation" requirement and of the
requirement to meet the Employment Standard, so long as the Tenant starts and
promptly completes repairs and resumes the business operations of the Tenant as
soon as repairs are complete, but in any event not later than 12 months from the
date the business operations of the Tenant were suspended as the result of an
Occurrence.

       12.  Condemnation Provisions.
            ------------------------

            A.  If title to the whole or substantially all of the Premises is
taken or condemned by any competent authority (save for the City of Grants) for
any public or quasi-public use, at the option of the Tenant to be exercised by
the Tenant giving written notice to the Landlord within 30 days of the taking or
condemnation, this Lease will cease and terminate, all monetary obligations
payable or performable by the Tenant as provided in this Lease will be prorated
as of the date of vesting title in the condemnation proceedings, and the total
award made with respect to the Premises less all expenses incurred with respect
to the condemnation action (the "Net Award"), will be apportioned between the
Landlord and the Tenant as provided in this Lease subject to the rights of any
Leasehold Mortgagee. The amount of the damages to which the Tenant is entitled
will first be used by the Tenant to obtain a complete release of any Leasehold
Mortgage.

            B.  If title to less than the whole or substantially all of the
Premises is taken or condemned by any competent authority for any public or
quasi-public



                                     -18-
<PAGE>
 
use, and the portion of the Premises not taken is sufficient for the continued
operation of the Premises as contemplated by this Lease, the Rent and the other
obligations payable and performable by the Tenant as provided in this Lease for
the remainder of the Term will be reasonably reduced by the Landlord, in
Landlord's reasonable discretion.

        C.  The rights of the Landlord and the Tenant to the Net Award on a
taking or condemnation will be determined as follows and in the following order
of priority:

            (1)  If a taking, partial, whole or substantially all, as the case
may be, occurs, the Landlord will be entitled to receive that portion of the
award, with interest on the award, representing compensation for the value of
the Land taken, including consequential damage to any part of the Premises not
taken, and damages measured by the difference in value of the Land immediately
before and after the taking. The Land will be considered as vacant unimproved
land, unencumbered by this Lease.

            (2)  If the whole or any part of the Premises is taken, the balance
of the award after payment of the portion specified in the preceding subsection
to the Landlord will be paid to the Tenant, except that if any Buildings
existing on the Premises are damaged or partially destroyed by a partial taking
of less than the whole or substantially all of the Premises, and this Lease is
not surrendered and terminated by the Tenant as provided in this paragraph, the
Tenant will rebuild, repair or replace the Buildings, (the "Repair") subject to
the following provisions:

                 (a)  If infrastructure site improvements other than Buildings
are taken or damaged, the Tenant will Repair the infrastructure site
improvements within portions of the Premises not taken but needed for the
business of the Tenant.

                 (b)  If the Buildings are damaged or partially destroyed by a
partial taking and the remaining portion of the Buildings can reasonably be
restored as a complete building capable of producing a fair and reasonable
proportionate return, the Tenant will repair, replace or rebuild the Buildings
in a reasonable manner.

                 (C)  If the Buildings are damaged or partially destroyed by a
partial taking, and the Buildings cannot reasonably be Repaired as provided in
this paragraph, the Tenant will demolish the remaining portion of the Buildings
and clear and reclaim the Land. The Tenant will Repair the Buildings with
Buildings of comparable quality and characteristics to the extent that the
remaining portion of the Premises can reasonably accommodate the Buildings.

        D.  The Tenant will not be required to spend sums in the Repair of



                                     -19-
<PAGE>
 
the Buildings over the sums paid to the Tenant as provided in this paragraph.

            E.  If the values of the respective interests of the Landlord and
the Tenant are determined as provided in this paragraph in the condemnation
action, the values so determined will be conclusive upon the Landlord and the
Tenant. If the values are not separately determined, the values will be
determined by the Landlord and the Tenant.

            F.  The Landlord, the Tenant, and any person or entity having an
interest in the award or awards will have the right to participate in any
condemnation action for the purposes of protecting their interests. Each party
so participating will pay its own expenses.

            G.  If the whole or any part of the Premises is taken or condemned
by any competent authority solely for the temporary use or occupancy of the
authority, this Lease may be terminated by the mutual agreement of Landlord and
Tenant.

        13.  Assignment or Subletting.
             -------------------------

             Subject to the Leasehold Mortgage paragraph of this Lease, the
                            ------------------
Tenant will not sell, assign, mortgage, pledge or transfer any interest in this
Lease and will not sublet all or any part of the Premises or permit anyone to
use or occupy the Premises without the prior written approval of the Landlord,
which approval may be unreasonably and arbitrarily delayed, deferred or denied.

        14.  Indemnity.
             ---------

             A.  The Tenant will indemnify and defend the Landlord against any
expense, loss or liability, resulting from:

                 (1)  Liens;

                 (2)  Claims and awards of damage for death, injury or property 

damages with respect to the Premises;

                 (3)  Delay by the Tenant in surrendering the Premises,

including claims made by any succeeding tenant because of delay;

                 (4)  Failure of the Tenant to perform any obligation to be

performed by the Tenant as provided in this Lease;

                 (5)  Failure of the Tenant to protect the Landlord and the

Premises against Hazardous Materials as provided in Section 813(9) of this

Lease; and

                 (6) Actions or demands with respect to any of the foregoing

(the "Indemnities").

                 However, if Section 56-7-1 NMSA 1978 is applicable to this

Lease, the Indemnities will not extend to liability, claims, damages, losses or

expenses,



                                     -20-
<PAGE>
 
including fees of lawyers, relating to the construction, installation,
alteration, modification, repair, maintenance, servicing, demolition,
excavation, drilling, reworking, grading, paving, clearing, site preparation or
development of any real property or any improvement of any kind on, above or
under real property and arising out of (1) the preparation or approval of maps,
drawings, opinions, reports, surveys, change orders, designs or specifications
by the Landlord, or the agents or employees of the Landlord, or (2) the giving
of or the failure to give direction or instructions by the Landlord, or the
agents or employees of the Landlord, where the giving or failure to give
directions or instructions is the primary cause of bodily injury to persons or
damage to property.

            B.  The Tenant will reimburse the Landlord on demand for any payment
made by the Landlord to which the Indemnities relate, including the reasonable
lawyer fees and costs incurred by the Landlord in establishing the right of the
Landlord to indemnity as provided in this Lease.

            C.  The Tenant may contest the validity of, defend, settle and
compromise any matter to which the Indemnities relate.

            D.  The Landlord may post on the Premises at any time any reasonable
notices to protect the rights of the Landlord.

        15. End of Term.
            -----------

            A.  At the end of the Term, if Tenant is not then in default, the
Tenant will assume the Departure Obligation as defined in paragraph 1(C), and
will elect either the Building Transfer Obligation or the Reclamation
Obligation, and will promptly start to perform the obligation elected.

            B.  If the Tenant holds over beyond the end of the Term, the Tenant
will be a tenant-at-will at an annual Rent of $120,000, payable in twelve equal
monthly payments, and will vacate the Premises on demand of the Landlord or be
deemed to be in forcible detainer of the Premises.

        16. Default of Tenant; Remedies of Landlord.
            ---------------------------------------

            A.  The Tenant will be in default on the happening of any of the
following (the "Default of Tenant"):

                 (1) The failure of the Tenant to make timely payment of any
monetary obligations of the Tenant payable to the Landlord as provided in this
Lease within 30 days after Notice from the Landlord is given to the Tenant.

                 (2) The failure of the Tenant to perform within 30 days after
Notice from the Landlord is given to the Tenant with respect to any other
obligation of



                                     -21-
<PAGE>
 
the Tenant as provided in this Lease that can be performed within the 30-day
period.

                  (3)  The failure of the Tenant to start, within 30 days after
Notice from the Landlord, to perform any other obligation of the Tenant as
provided in this Lease that by the nature of this lease cannot be performed
within 30 days, and to complete correcting the failure to perform without
interruption and with diligence, such that the default will be fully cured
within ninety days.

                  (4)  Failure to meet the Employment Standard for a period of
more than 45 days after written notice has been given to Tenant by Landlord.
However, Tenant shall have a period of 45 days in which to reestablish
compliance with the Employment Standard in which event the default shall be
cured and the Lease shall remain in full force and effect, provided, however,
that the benefit of such notice and cure period shall not apply more often than
once in any two year period.

             B.  On the Default of Tenant, subject to the Leasehold Mortgage
                                                          ------------------
paragraph of this Lease, the Landlord will have all cumulative remedies
available to the Landlord at law or equity in New Mexico for the breach or
default of this Lease by the Tenant, including, without limitation, termination
of this Lease, retaking possession of the Premises with or without termination
of this Lease, and proceeding to recover any damages, including any unpaid
monetary obligations of the Tenant payable to the Landlord, or the value of any
unperformed obligations of the Tenant to be performed by the Tenant as provided
in this Lease.

        17.  Default of Landlord; Remedies of Tenant.
             ---------------------------------------

             A.  The Tenant will look solely to the estate of the Landlord in
the Land for the collection of any judgment or order requiring payment of money
by the Landlord if the Landlord defaults in or breaches this Lease; no other
assets of the Landlord will be subject to levy, execution or other judicial
process for the satisfaction of any claim of the Tenant; and the Landlord will
not be liable for any default or breach or for any indirect, special or
consequential damages except to the extent of the estate of the Landlord in the
Land.

             B.  If this Lease provides that the exercise of any right by
the Tenant or the performance of any obligations of the Tenant is subject to the
prior written consent of the Landlord and that the consent of the Landlord will
not be unreasonably withheld or delayed, then in any case in which the Landlord
withholds or delays the consent of the Landlord, the determination and action by
the Landlord will be final and conclusive upon the Tenant unless, however,
within 30 days after notice from the Landlord



                                     -22-
<PAGE>
 
of the determination of the Landlord, the Tenant files an action for declaratory
judgment or equitable relief in the appropriate court in Cibola County, New
Mexico, seeking declaratory or injunctive relief from the determination of the
Landlord, which declaratory or injunctive relief will be the sole remedy of the
Tenant for any withholding or delaying of consent by the Landlord. If any action
for declaratory or injunctive relief is filed by the Tenant as provided in this
Section, the sole issue will be the determination if the withholding or delaying
of consent by the Landlord was reasonable or unreasonable, and if a
determination is made that the withholding or delaying of consent by the
Landlord was unreasonable, then the decision will annul the withholding or
delaying of consent, the annulment being the sole remedy of the Tenant, the
Tenant and the Landlord intending (as to which the Tenant and the Landlord are
conclusively bound) no withholding or delaying of consent by the Landlord, or
any decision of any court with respect to the consent (i) will not impose any
financial liability upon or result in any damages being recoverable from the
Landlord; or (ii) create any right cognizable or remedy enforceable in favor of
the Tenant and against the Landlord in law or equity or under any special
statutory proceeding or at all (except as provided in this Section).

            C.  The obligations of the Landlord as provided in this Lease will
be deemed covenants, not conditions. The Landlord will not be in default as
provided in this Lease until the Landlord has failed to start performance within
30 days, or such additional time as is reasonably required, to correct the
default, after delivery of Notice by the Tenant to the Landlord specifying the
failure of the Landlord to perform any obligation as provided in this Lease.

            D.  The Tenant expressly waives any right to a trial by jury in any
action to enforce or defend any rights as provided in this Lease or as provided
in any amendment, instrument, document or agreement delivered, or later
delivered with respect to this Lease or arising from any landlord and tenant
relationship existing between the Landlord and the Tenant with respect to this
Lease. The Tenant agrees that any such action will be tried before a court of
competent jurisdiction and not before a jury.

        18.  Right to Charge.
             ---------------

             If the Tenant fails to pay or perform any obligation to be paid or
performed by the Tenant as provided in this Lease with respect to ad valorem
property taxes or to any other obligation non-payment or non-performance of
which could give rise to a Lien against the Land, the Landlord may make the
payment or perform the obligation, and the Tenant on demand will pay the
Landlord as additional Rent the amount reasonably



                                     -23-
<PAGE>
 
paid, or the reasonable cost of the performance, plus interest at the rate of
eighteen percent a year from the date of the payment or performance of the
Landlord, and reasonable fees of lawyers.

        19.  Development Cooperation.
             -----------------------

             The Landlord and Tenant will grant to public entities or public
service or utility corporations, for the purpose of serving the Premises and
adjacent real property owned, leased or otherwise controlled by the Tenant,
reasonable rights-of-way or easements on, under or over the Premises consistent
with ordinary business practices for vehicular access, for telephone,
electricity, water, sanitary or storm sewers and other utilities and municipal
or special district services.

        20.  Leasehold Mortgages.
             --------------------

             A.  Leasehold Mortgages Authorized. The Tenant may mortgage the
                 ------------------------------                           
Leasehold Estate to one Leasehold Mortgagee or to a syndicate of Leasehold
Mortgagees, provided the loan is serviced by a single entity. All of the rights
of the Landlord reserved or granted in this Lease will be subject to the rights
of any such Leasehold Mortgage as provided below.

             B.  Notice to Landlord.
                 -------------------

             The Tenant will provide notice to the Landlord of any Leasehold
Mortgage, and will provide a copy of the Leasehold Mortgage, any changes with
respect the Leasehold Mortgage during the term of the Leasehold Mortgage, and
the name, telephone and fax numbers and mailing and surface address of the
Leasehold Mortgagee.

             C.  Consent of Leasehold Mortgagee Required. No cancellation,
                 -----------------------------------------                
surrender or modification of this Lease will be effective as to any Leasehold
Mortgagee unless first approved in writing by the Leasehold Mortgagee.

             D.  Default Notice. The Landlord, on providing the Tenant the
                 --------------                                                 
Notice of (i) Default of Tenant as provided in this Lease, or (ii) any act or
omission of the Tenant on which the Landlord may claim a default, will provide a
copy of the Notice to any Leasehold Mortgagee. If, because of the Default of
Tenant, the Landlord elects to terminate this Lease, the Notice of the Landlord
to the Tenant will include the date on which the Landlord intends to terminate
this Lease. No Notice by the Landlord to the Tenant will be deemed to have been
given unless a copy of the Notice has been given to the Leasehold Mortgagee.
When the Notice has been given to a Leasehold Mortgagee, the Leasehold Mortgagee
will have 20 days to remedy any Default of Tenant or acts or omissions provided
for in the Notice, and in each instance the additional periods of time

provided for in this Leasehold Mortgages paragraph of this Lease (the "Grace
                     --------------------                                   
Period"), to remedy, start remedying, or cause to be remedied the Defaults of
Tenant or acts or omissions provided for in the Notice. The Landlord will accept
performance by a Leasehold Mortgagee as if the performance were done by the
Tenant. The Landlord will not terminate this Lease if during the Grace Period
the Leasehold Mortgagee:

            (1)  Gives Notice to the Landlord of the desire of the Leasehold
Mortgagee to pay and perform, and does in fact pay and perform before the end of
the Grace Period, all the Rent (including the Employment Standard) and the other
obligations of the Tenant payable to the Landlord as provided in the Notice of
default and which may become due during the Grace Period, and

            (2)  using the diligent best efforts of the Leasehold Mortgagee,
complies in good faith with reasonable diligence all other obligations of the
Tenant as provided in this Lease.

        E.  Procedure on Default.
            ---------------------

            (1)  If despite payment and performance of the Leasehold Mortgagee
as provided in the preceding subparagraph, the Landlord elects to terminate this
Lease by reason of the Default of Tenant, the specified date for the termination
of this Lease as fixed by the Landlord in the Notice of Default of Tenant will
be extended for a period of 90 days (the "Additional Grace Period") if the
Leasehold Mortgagee during the 90-day period:

                 (a)  Pays and performs the Rent, including the Employment
Standard, and any other obligations of the Tenant payable to the Landlord as
provided in this Lease as the Rent and other obligations become due, and
continues the diligent good faith best efforts of the Leasehold Mortgagee to
perform all of the other obligations of the Tenant as provided in this Lease;
and

                 (b)  If not enjoined or stayed, takes steps to acquire or sell
the Leasehold Estate by foreclosure of the Leasehold Mortgage or other
appropriate means and prosecutes the foreclosure to completion with due
diligence.

            (2)  If, at the end of the Additional Grace Period, the Leasehold
Mortgagee is complying with this Leasehold Mortgages paragraph of this Lease, 
                                 -------------------
this Lease will not then terminate and the time for completion by the Leasehold 
Mortgagee of the foreclosure proceedings of the Leasehold Mortgagee will 
continue so long as the Leasehold Mortgagee is enjoined or stayed and later
for so long as the Leasehold Mortgagee proceeds to complete steps to acquire or
sell the Leasehold Estate by



                                     -25-
<PAGE>
 
foreclosure of the Leasehold Mortgage or by other appropriate means with
reasonable diligence and continuity. If the Default of Tenant is cured and the
Leasehold Mortgagee discontinues the foreclosure action, this Lease will
continue in full force and effect as if the Tenant had not defaulted.

            (3) If a Leasehold Mortgagee is complying with this Leasehold
                                                                ---------
Mortgages paragraph of this Lease, on acquisition of the Leasehold Estate by the
- ---------                                                                      
Leasehold Mortgagee or any other acquirer, this Lease will continue in full
force and effect as if the Tenant had not defaulted, subject to the reasonable
prior approval by Landlord of the acquirer.

            (4) For the purpose of this Leasehold Mortgages paragraph of this
                                        -------------------                 
Lease, any acquirer of the Leasehold Estate will be deemed to have agreed to
perform all of the obligations of the Tenant to be performed as provided in this
Lease only for so long as the acquirer is the owner of the Leasehold Estate. If
the Buildings have been or become materially damaged on, before or after the
date of the purchase and assignment of the Leasehold Mortgage, the Leasehold
Mortgagee or the acquirer will be obligated to Repair the Buildings only to the
extent of the net insurance proceeds received by the Leasehold Mortgagee or the
acquirer by reason of the damage. The Landlord will have the right to reasonably
approve any acquirer of the Leasehold Estate other than the Landlord, and the
Landlord will have reasonable discretion with respect to the decision to approve
or not approve such an acquirer of the Leasehold Estate. In exercising such
reasonable discretion of the Landlord, the Landlord may take the ability of the
acquirer of the Leasehold Estate to pay and perform the Rent, including the
Employment Standard, in consideration.

          F.  Substitute Lease. If the Landlord terminates this Lease because 
              ----------------                                     
of a Default of Tenant, the Landlord will, in addition to providing the notices
of default and termination as required by this Leasehold Mortgages paragraph 
                                               -------------------
of this Lease, provide the Leasehold Mortgagee with (i) a Notice that the Lease
has been terminated (ii) a statement of all sums which would at that time be due
as provided in this Lease except for the termination, and (iii) a statement of
all other defaults, if any, known to the Landlord. The Landlord will enter into
a Substitute Lease (the "Substitute Lease") of the Premises with the Leasehold
Mortgagee for the remainder of the Term, effective as of the date of termination
of this Lease, at the Rent (including the Employment Standard) and the other
obligations of the Tenant payable and performable to the Landlord and on the
terms of this Lease, if the Landlord approves the acquirer of the Leasehold
Estate as provided in this



                                     -26-
<PAGE>
 
Lease, and:

             (1)  The Leasehold Mortgagee gives a Notice to the Landlord
requesting the Substitute Lease within 30 days after the date the Leasehold
Mortgagee receives the termination Notice from the Landlord; and

             (2)  The Leasehold Mortgagee pays to the Landlord at the time of
the signing and delivery of the Substitute Lease any and all sums which would be
due but for the termination; and

             (3)  The Leasehold Mortgagee agrees to remedy any of the Default of
Tenant of which the Leasehold Mortgagee was notified by the termination Notice
of the Landlord and which are reasonably susceptible of being so cured by the
Leasehold Mortgagee.

             The new tenant as provided in the Substitute Lease will have the
same right, title and interest in and to that portion of the Premises subject to
the Substitute Lease as the Tenant had. The new tenant as provided in the
Substitute Lease will be liable to perform the obligations imposed on the new
tenant by the Substitute Lease (including the Employment Standard) only during
the period the new tenant has ownership of the Leasehold Estate.

          G.  Legal Actions. The Landlord will give the Leasehold Mortgagee 
              -------------                                    
prompt Notice of any legal action between the Landlord and the Tenant
or between the Landlord, the Tenant and any condemning authority involving
obligations as provided in this Lease. The Leasehold Mortgagee will have the
right to intervene in the action and become a party to the action, and the
Landlord and the Tenant will approve the intervention. If the Leasehold
Mortgagee elects not to intervene or become a party to the action, the Landlord
will give the Leasehold Mortgagee or other acquirer Notice of, and a copy of,
any award or decision made in the action.

          H.  Future Amendments. If any Leasehold Mortgagee to which the Tenant 
              -----------------                                       
proposes to make a Leasehold Mortgage on the Leasehold Estate requires as a
condition to making any loan secured by the Leasehold Mortgage that the Landlord
agree to amendments of this Lease, the Landlord will enter into an agreement
with the Tenant in recordable form making the amendments that are requested by
the Leasehold Mortgagee only if the changes are reasonable in the sole and
absolute discretion of the Landlord. However, the Landlord will not be required
to make any agreement that changes the Premises; decreases the Rent (including
the Employment Standard or other obligations of the Tenant payable or
performable to the Landlord as provided in this Lease; enlarges the



                                     -27-
<PAGE>
 
Term; requires spending funds by the Landlord which the Landlord is not
obligated to spend as provided in this Lease; or in any way enlarges the
obligations of the Landlord as provided in this Lease. The foregoing enumeration
is not intended as a limitation on the right of the Landlord to refuse to
consent to an amendment if the Landlord acts reasonably. All expenses incurred
by the Landlord with respect to any amendment will be paid by the Tenant or
reimbursed by the Tenant to the Landlord.

             I.  Estoppel Certificate. The Landlord will, without charge, at
                 --------------------                                     
any time after the date of this Lease, but not more frequently than twice in any
12-month period, within 30 days after Notice of a written request from the
Tenant to the Landlord, certify as to the status of the Lease and consent to the
assignment by the Tenant of this Lease as additional collateral for the benefit
of any Leasehold Mortgagee.

        21.  Bankruptcy; Insolvency. The Tenant will be deemed to be in
             ----------------------                                  
default as provided in this Lease (without the Landlord giving any notice
declaring the default), if all or substantially all of the assets of the Tenant
are placed in the hands of a receiver or trustee, or if the Tenant files a
voluntary petition in bankruptcy, makes an assignment for the benefit of
creditors, admits in writing that the Tenant cannot pay the debts of the Tenant
as the debts become due, or is finally adjudicated a bankrupt, or if the Tenant
petitions or institutes any proceedings under the United States Bankruptcy Code
or under any other similar law.

             If a receiver, trustee or debtor-in-possession seeks to assume this
Lease under the provisions of the Code or under some similar bankruptcy or
insolvency statute, then this Lease or any interest in and to the Premises will
not become an asset in any of the proceedings, will not be assumed and will not
be assignable by the receiver, trustee or debtor-in-possession, unless the
receiver, trustee or debtor-in-possession, within the time provided under the
Code or statute cures all outstanding defaults and gives adequate assurances of
future performance, including without limitation, assurances with respect to the
payment and performance of the Rent (including the Employment Standard) and the
other obligations of the Tenant as provided in this Lease, including the use and
operation provisions of this Lease. In any such event as provided in this Lease
in which the cures are not made or the adequate assurances are not given within
the time provided, this Lease will be deemed rejected and the Landlord may, in
addition to any and all rights or remedies of the Landlord as provided in this
Lease or at law, but subject to the rights of any Leasehold Mortgagee, reenter
the Premises and take possession of the Premises and remove all persons and
contents from the Premises and neither the Tenant, nor any



                                     -28-
<PAGE>
 
guarantor of this Lease, nor any such receiver, trustee, debtor-in-possession,
committee of creditors or other legal entity created by such bankruptcy laws
will have further claim as provided in this Lease or any further interest in the
Premises.

             As used in this Lease, the phrase "adequate assurances" means clear
and convincing evidence that the Tenant obligations as provided in this Lease
and as provided in the Code are likely to be timely performed during the entire
remaining balance of the term of this Lease and the person or entity which is to
render the performance has demonstrated to the satisfaction of the Landlord
substantial experience (for the use permitted in this Lease), has specifically
assumed the obligations of the Tenant as provided in this Lease, and is
contractually bound directly to the Landlord, taking into consideration that
full performance of the Lease, including continued satisfaction of the
Employment Standard, was a material inducement for the Landlord to enter into
this Lease.

        22.  Recording; Documents Affecting Title and Interest. The Tenant will 
             -------------------------------------------------          
not do any act which may encumber the interest or title of the Landlord in and
to the Land.

        23.  General Provisions. For the purpose of this Lease:

either the Landlord or the Tenant as provided in this Lease, is taken at the
expense of the actor unless otherwise specifically provided in this Lease. If
the Tenant requests anything of the Landlord that requires preparation of, or
review of, documents by the lawyers of the Landlord and if the Landlord accedes
to such request, the Tenant will reimburse the Landlord on demand any reasonable
legal fees and expenses incurred by the Landlord incident to the preparation or
review as additional Rent as provided in this Lease.

             C.  Approval. Except with respect to the Assignment and Subletting
                 --------                             -------------------------
section of this Lease, the response to any request for approval as provided in
this Lease will not be unreasonably or arbitrarily withheld, delayed or

             D.  Computation of Time. In computing any period of time by days

as provided in this Lease, the date of the act, event or default from which the
designated period of time starts to run will not be included. The last day of

                            Attention: William R. Roberts, Esq

            F.  Waiver; Remedies. No waiver of any default as provided in this 
                ----------------                                       
Lease or delay or omission in exercising any right or power of the Landlord or
the Tenant will be considered a waiver of any other default as provided in this
Lease. No exercise or failure to exercise any right or power of the Landlord or
the Tenant as provided in this Lease will be considered to exhaust that right or
power. The exercise of or failure to exercise any one of the rights and remedies
of the Landlord or the Tenant as provided in this Lease will not be deemed to be
instead of, or a waiver of, any other right or remedy as provided in this Lease.
The Tenant may waive any of the terms or conditions precedent to the obligations
of the Tenant as provided in this Lease. Failure on the part of the Landlord to
complain of any action or nonaction on the part of the Tenant, no matter how
long the action or nonaction on the part of the Tenant may continue, will not be
deemed to be a waiver by the Landlord of any of the rights of the Landlord as
provided in this Lease. Further, no waiver at any time of any of the terms of
this Lease by the Landlord will be construed as a waiver of any of the other
terms of this Lease and a waiver at any time of any of the terms of this Lease
will not be construed as a waiver at any later time of the same provisions. The
consent by the Landlord to or of any action by the Tenant requiring the consent
of the Landlord will not be deemed to waive or render unnecessary consent of the
Landlord to or of any later similar act by the Tenant.

            G.  Time of Essence. Time is of the essence in the performance
                ---------------                                   
of all the terms of this Lease.

supersedes all previous agreements, written or oral, between the Landlord and
the Tenant. No statement, promise, or inducement made by the Landlord or the
Tenant, or the agent of

this Lease, is binding upon the Landlord or the Tenant.

application of the term to any person or circumstance is, to any extent, invalid
or unenforceable, the remainder of this Lease, or the application of the term to
persons or circumstances other than those as to which the term is held invalid
or unenforceable, will not be affected by the application, and each term of this
Lease will be valid and be enforced to the fullest extent permitted by law.

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

                  --------                                         
and all Rent and obligations owing by the Tenant to the Landlord as provided in
this Lease will survive the end or termination of this Lease.

              P.  Construction. Despite any term to the contrary in this
                  ------------                                        
Lease, this Lease may be modified, amended, discharged, changed or waived only
in writing, signed by the party against which enforcement of the modification,

itself specifies that all modification to the contract must be in writing. This
sentence is intended by the Landlord and the Tenant to incorporate the holding

v. Manville Products Corp., 108 N.M. 643, 777 P.2d 371 (1989), that where the
- --------------------------                                                 
contract requires that any modification be in writing, oral modifications are
ineffectual. Neither the Landlord nor the Tenant will ever assert or claim in
any action or arbitration with respect to this Lease that any term of this Lease
was modified in any respect, including by a "course of conduct," "course of
dealing" or by a "waiver or estoppel," except by a written amendment of this
Lease signed by the Landlord and the Tenant. Further, the language used in this
Lease will be construed according to the fair and usual meaning of the language,
and will not be' strictly construed for or against the Landlord or the Tenant.
The Landlord and the Tenant intend that the language used in this Lease means
what the language says. If a matter is specifically covered by the written terms
of this Lease, no agreement with respect to the matter will be implied on the
theory of good faith or fair dealing or any other theory.

            Further, the Landlord and the Tenant intend that the rights and
remedies provided in the Lease are plain, adequate and complete and, in any
action or arbitration with respect to this Lease, no need exists for any court
or board of arbitrators to impose equitable solutions, such as judicially
imposed accountings, to meet any problem presented.

            The Landlord and the Tenant have each been represented by capable
and competent counsel with respect to this Lease and no great disparity exists
in the bargaining power of the Landlord and the Tenant.

            The Landlord and the Tenant also each recognize that the Lease
creates both property rights and contract rights within a sophisticated
commercial setting and that the relationship of the Landlord and the Tenant does
not create fiduciary duties or responsibilities as between the Landlord and the
Tenant.

        Q.  Attorneys' Fees. If the Landlord or the Tenant is required to
            ---------------                                         
initiate or defend litigation or other legal action in any way with respect
to this Lease, the prevailing party in the litigation or action, in addition to
any other relief that may be granted, whether legal or equitable, will be
entitled to reasonable attorneys' fees. Attorneys' fees will include attorneys'
fees on any appeal, and, in addition, a party entitled to attorneys' fees will
also be reimbursed for all other reasonable costs for investigating the action,
taking depositions, conducting other discovery, travel, and all other necessary
costs



                                     -33-

incurred in the litigation. All fees due as provided in this Lease will be paid
whether or not the litigation is prosecuted to judgment.

                                        May __, 1998

Mr. Bob Clark
Colorado Greenhouse, Inc.
6811 Weld County Road 31
Fort Lupton, CO 80621

                                        City of Grants
                                        --------------

Dear Mr. Clark:

The City of Grants, New Mexico and Colorado Greenhouse, Inc. entered into a
Lease and Project Participation Agreement (the "Lease") on __________ , 1998.
The Lease requires the Company to operate two greenhouses and related facilities
for a period of 60 years. This letter notifies you of the manner in which the
City can now furnish its water and wastewater treatment to the Company for use
by the Company in its greenhouse facilities. Water and wastewater treatment will
be furnished pursuant to City ordinances and policies on water and wastewater,
as those ordinances and policies may be modified from time to time.

The City currently owns and operates its water and wastewater systems. As long
as the City continues to own and operate its water, the City will provide water
(as opposed to wastewater) services to the Company at the same rates and on the
same terms generally made available to industrial water users under City
ordinance. We understand that the Company will not require in excess of 360 acre
feet of water per year. Because the greenhouses will discharge a high volume of
relatively clean wastewater from its greenhouse operation, the City does not
expect that the Company's wastewater use will be comparable to that of an
average commercial wastewater system user. The City anticipates that substantial
amounts of the wastewater will be able to be discharged directly to the Coyote
del Mal Pais Golf Course without treatment, for reuse as golf course irrigation.
The City will provide separate meters for domestic and greenhouse uses. The City
will only bill Colorado Greenhouse for sewage treatment on the amount of water
utilized for domestic purposes, as long as the City continues to own and operate
its own wastewater system and the Coyote del Mal Pais Golf Course.



                                  EXHIBIT A-1
                                  -----------
                                 Page -1- of 2
<PAGE>
 
The provisions of the City's water and wastewater ordinances will need to be
complied with by the Company, including prompt payment of all fees and charges
associated with the connection and use of the City's water and wastewater
systems.

If the City elects to sell its water and wastewater utilities (which is not
currently contemplated) or the Coyote del Mal Pais Golf Course (also not
currently contemplated), the City would be willing to work with the purchaser in
good faith in an effort to enable Colorado Greenhouse to continue to receive
water and wastewater services on the same basis as users in the same
classification.

Please indicate your acknowledgment by signing this letter in the space below
and returning a copy to us.

Sincerely,

CITY OF GRANTS

City to which the Indemnities relate, including the reasonable lawyer fees and

required for routine inspections and maintenance and work on the Easement
Property which does not involve more workers or equipment than routine

exceptions listed on Exhibit E (the "Permitted Exceptions"), the City is the fee
                     ---------

presence, release or threatened release by CGI or its affiliates, agents,
employees, contractors, sublessees, successors or assigns of Materials of
Environmental Concern, the City shall be held harmless from and against all such

action shall be borne by CGI. For purposes of this Agreement the term "Materials

such terms are defined in or identified by any Environmental Law. For purposes
of this Agreement the term "Environmental Laws" shall mean all existing or
future federal, state, local and foreign laws, statutes, ordinances, rules,
regulations, administrative orders, and final decisions of judicial bodies or
administrative agencies (to the extent the issuing governmental authority has
jurisdiction over the Easement Property), including without limitation any
common law theory of liability, in any case relating to regulation or control of
pollution, or to protection of human health or the environment from or with
respect to Materials of Environmental Concern.

     9.   Reservation of Rights. The City reserves the right to use and enjoy
          ---------------------

City will use water from the pond located on the Golf Course Property for
irrigation purposes on its golf course or elsewhere. In connection therewith the
City agrees to maintain such pond and remove therefrom on a regular basis
sufficient water for the pond to adequately hold all effluent transported by CGI
to such pond on a daily basis. In addition, the City acknowledges that it has
been furnished with a projected chemical composition of the effluent water to be
so transported and agrees that for so long as the quality of such water is
within the standards set forth on Exhibit F attached hereto and made a part
                                  ---------
hereof, the City will accept such water.

     11.  Default: Remedies.
          -----------------

          a.  Should the City or CGI fail to perform any covenant or comply with
any condition required to be performed under this Agreement or the Lease within
60 days after written demand by the other party (or such longer period as may be
reasonably required to cure such failure to perform or comply if such cure is
commenced within such 60-day period), the non-performing party shall be in
default of its obligations under this Agreement and under the Lease allowing the
non-performing party to pursue rights and remedies available to it under the
Lease.

          b.  In the event a default under this Agreement is not cured within
the applicable cure period (if any), the non-defaulting party shall be entitled
to pursue any and  all remedies available to it at law or in equity, including
without limitation the remedy of specific performance, or termination of this
Agreement upon ten additional days' written notice. To the maximum extent
permitted by law, should either party be in default under this Agreement the
defaulting party covenants and agrees to pay and discharge all reasonable costs
and expenses which shall be incurred by the non-defaulting party arising out of
such default, in enforcing the covenants and agreements of this Agreement,
including without limitation reasonable attorneys' fees. Notwithstanding the
foregoing, in no event shall either party be liable for any consequential or
punitive damages, damages for lost business, lost profits, or opportunities

relinquished except by written instrument signed by the party to be charged with
such waiver. Failure by any party to this Agreement to enforce any provision of
this Agreement shall not constitute a waiver of such provision, and no waiver by
any party to this Agreement of any provision of this Agreement on one occasion
shall constitute a waiver of any other provision or of the same provision on
another occasion.

     13.  Captions; Definitions. The section and subsection captions used in
          ---------------------

Mr. Bob Clark
Colorado Greenhouse, Inc.
6811 Weld County Road 31
Fort Lupton, CO 80621

                                       City of Grants
                                       --------------

Dear Mr. Clark:

The City of Grants, New Mexico and Colorado Greenhouse, Inc. entered into a
Lease and Project Participation Agreement (the "Lease") on May 14 1998. The
                                                           -------          
Lease requires the Company to operate two greenhouses and related facilities for
a period of 60 years. This letter notifies you of the manner in which the City
can now furnish its water and wastewater treatment to the Company for use by the
Company in its greenhouse facilities. Water and wastewater treatment will be
furnished pursuant to City ordinances and policies on water and wastewater, as
those ordinances and policies may be modified from time to time.

The City currently owns and operates its water and wastewater systems. As long
as the City continues to own and operate its water, the City will provide water
(as opposed to wastewater) services to the Company at the same rates and on the
same terms generally made available to industrial water users under City
ordinance. We understand that the Company will not require in excess of 360
acre feet of water per year. Because the greenhouses will discharge a high
volume of relatively clean wastewater from its greenhouse operation, the City
does not expect that the Company's Wastewater use will be comparable to that of
an average commercial wastewater system user. The City anticipates that
substantial amounts of the wastewater will be able to be discharged directly to
the Coyote del Mal Pais Golf Course without treatment, for reuse as golf course
irrigation. The City will provide separate meters for domestic and greenhouse
uses. The City will only bill-Colorado Greenhouse for sewage treatment on the
amount of water utilized for domestic purposes, as long as the City continues to
own and operate its own wastewater system and the Coyote del Mal Pais Golf
Course.

<PAGE>
 
The provisions of the City's water and wastewater ordinances will need to be
complied with by the Company, including prompt payment of all fees and charges
associated with the connection and use of the City's water and wastewater
systems.

If the City elects to sell its water and wastewater utilities (which is not
currently contemplated) or the Coyote del Mal Pais Golf Course (also not
currently contemplated), the City would be willing to work with the purchaser in
good faith in an effort to enable Colorado Greenhouse to continue to receive
water and wastewater services on the same basis as users in the same
classification.

Please indicate your acknowledgment by signing this letter in the space below
and returning a copy to us.

Sincerely,

CITY OF GRANTS

                             MASTER LOAN AGREEMENT

     THIS MASTER LOAN AGREEMENT is entered into as of this 24th day of January,
1997, by and between COLORADO GREENHOUSE, INC., a Delaware corporation doing
business in Colorado ("CGI"), and COLORADO SPRINGS PRODUCTION CREDIT
ASSOCIATION, a federally chartered association of the Farm Credit System
("Lender").

                                   RECITALS

     From time to time CGI may request and Lender may make loans to CGI . In
order to reduce the amount of paperwork associated therewith, Lender, and CGI
would like to enter into a Master Loan Agreement (the "MLA"). For that reason,
and in consideration of Lender's making one or more loans to CGI, Lender, and
CGI agree as follows:

                                   ARTICLE 1

                           SUPPLEMENTS, DEFINITIONS

     SECTION 1.1  SUPPLEMENTS.  In the event CGI desires to borrow from Lender
and Lender is willing to lend to CGI , or in the event Lender and CGI desire to
consolidate any existing loans hereunder, the parties will enter into a
Supplement to the MLA (a "Supplement"). Each Supplement will set forth the
amount of the loan, the purpose of the loan, the interest rate or rate options
applicable to that loan, the repayment terms of the loan, and any other terms
and conditions applicable to that particular loan. Each loan will be governed by
the terms and conditions contained in the MLA and in the Supplement relating to
the loan. In the event of any conflict with the terms of the MLA or any new
matter introduced in any Supplement, the terms of the Supplement, for that
Supplement, shall be controlling.

     SECTION 1.2  DEFINITIONS.  For the purpose of the MLA, and for the purposes
of the MLA and any Supplement (the MLA, Supplements and all other Loan
Documents, together being sometimes referred to as the "Agreement"), except as
otherwise expressly provided or unless the context otherwise requires, the
capitalized terms used shall have the following meanings:

     ADVANCE shall mean an advance of funds by Lender to CGI pursuant to any
     Supplement.

     AFFILIATE shall mean, as to any Person, any other Person (a) that directly
     or indirectly, through one or more intermediaries, controls or is
     controlled by, or is under common control with, such Person; (b) that

                                   ARTICLE 2

                              GENERAL CONDITIONS

     SECTION 2.1  AVAILABILITY.  Advances will be made available on any Business
Day upon the telephonic or written request of CGI. Requests for Advances must be
received no later than 12:00 noon Mountain Time on the date the loan is desired.
Advances will be made available by wire transfer of immediately available funds
to such account or accounts as may be authorized by CGI. CGI shall furnish to
Lender a duly completed and executed copy of a Delegation and Wire Transfer
Authorization Form, and Lender shall be entitled to rely on (and shall incur no
liability to CGI in acting on) any request or direction furnished in accordance
with the terms thereof.

     SECTION 2.2  REPAYMENT.  CGI's obligation to repay each Advance shall be
evidenced by the promissory note set forth in the Supplement relating to that
Advance. Lender shall maintain a record of all Advances, the interest accrued
thereon, and all payments made with respect thereto, and such record shall,
absent proof of manifest error, be conclusive evidence of the outstanding
principal and interest on the Advances. All payments shall be made by wire
transfer of immediately available funds, or by check, without setoff, deduction
or counterclaim. Wire transfers shall be made to ABA No. 101104562 for advice to
and credit of Lender (or to such other account as Lender may direct by notice).
CGI shall give Lender telephonic notice no later than 12:00 noon Mountain Time
of its intent to pay by wire and funds received after 2:00 p.m. Mountain Time
shall be credited on the next business day. Checks shall be mailed to Farm
Credit Bank of Wichita, 245 N. Waco, Wichita, KS 67201-2940 (or to such other
place as Lender may direct by notice). Credit for payment by check will not be
given until the latter of: (a) the day on which Lender receives immediately
available funds; or (b) the next business day after receipt of the check.

     SECTION 2.3  CAPITALIZATION.  Stock purchase and conversion shall be made
according to the terms, conditions and designations outlined in the Farm Credit
Act of 1971, as amended (12 U.S.C. (S) 2074), regulations and Lender's bylaws,
including without limitation Lender's statutory first Lien on CGI's stock in
Lender, which Lien CGI acknowledges and expressly hereby grants to Lender. CGI
acknowledges that retirement of stock will be in accordance with Law, regulation
and Lender's bylaws. If an Event of Default shall occur and continue after any
applicable grace period, Lender may retire the stock at book value (not to
exceed par value or face amount) and apply the proceeds to the principal amount
of the Advances outstanding at the time, or to interest, in accordance with Law,
regulations and Lender's bylaws in effect at the time of retirement. If book
value of stock is ever less than par value or face amount of if Lender's capital
becomes impaired, Lender may retire stock in an amount equal to book value. Such
a retirement will in no way affect CGI's obligations under the Loan Documents,
including any amounts borrowed to purchase stock.

     SECTION 2.4  SECURITY.  To secure the payment of the Advances and the
performance of all obligations of Debtor under the Loan Documents, Debtor
hereby grants to Lender a continuing security interest in and to the following
property and interests in property of Debtor, whether now owned or existing or
hereafter acquired or arising and wheresoever located: all Accounts, Inventory,
Equip-

                                       4

ment, Fixtures, Farm Products, General Intangibles, Chattel Paper, Instruments,
Documents, Intellectual Property (including specifically without limitation
patents and patent licenses, trademarks, design marks, word marks, tradenames,
logos, and good will connected therewith), and all accessions to, substitutions
for, and all replacements, products and proceeds of the foregoing (including
without limitation, proceeds of insurance policies insuring any of the
foregoing), all books and records (including without limitation customer lists,
credit files, computer programs, printouts, data whether stored electronically
or otherwise, and other computer materials and records) pertaining to any of the
foregoing, and all insurance policies insuring any of the above collateral (the
"Collateral").

     SECTION 2.5  CAPITAL ADEQUACY.  If after the date hereof Lender shall have
determined that the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change therein, or any change in the interpretation or
administration thereof by the Farm Credit Administration ("FCA"), Lender's
regulator, or any successor agency thereto, or compliance by Lender with any
request or directive regarding capital adequacy (whether or not having the force
of law) of FCA, has or would have the effect of reducing the rate of return on
Lender's capital as a consequence of its obligations hereunder or the
transactions contemplated hereby to a level below that which Lender could have
achieved but for such adoption, change or compliance (taking into consideration
Lender's policies with respect to capital adequacy) by an amount deemed by
Lender to be material, then from time to time, within ten (10) Business Days
after demand by Lender, CGI shall pay to Lender such additional amount or
amounts as will compensate Lender for such reduction.  A certificate of Lender
claiming compensation under this section and setting forth the additional amount
or amounts to be paid to it hereunder shall be conclusive, provided that the
determination thereof is made on a reasonable basis. However, to the extent
capital costs relate to Lender's loans in general and not specifically to a loan
hereunder, Lender shall use reasonable averaging and attribution methods.  In
addition, Lender agrees that, as promptly as practical after it becomes aware of
the occurrence of an event or the existence of a condition that would entitle it
to exercise its rights under this Section, it will use commercially reasonable
efforts to make, fund or maintain the affected Advances through another
participant if (1) as a result thereof the additional money that would otherwise
be required to be paid in respect of such Advances would be reduced, and (2) the
making, funding or maintaining of such Advances through such other participant
would not adversely affect such Advances or Lender.  Finally, if Lender is to
require CGI to make payments under this Section then Lender must make a demand
on CGI to make such payment within ninety (90) days of the later of (1) the date
on which such capital costs are actually incurred by Lender, or (2) the date
on which Lender knows, or should have known, that such capital costs have been
incurred by Lender.

     SECTION 2.6  BROKEN FUNDING SURCHARGE.  Notwithstanding any provision
contained in any Supplement giving CGI the right to repay any loan prior to the
date it would otherwise be due and payable, CGI agrees that in the event it
repays any fixed rate balance prior to its scheduled due date or prior to the
last day of the fixed rate period applicable thereto (whether such payment is
made voluntarily, as a mandatory prepayment, as a result of an acceleration,
or otherwise), CGI will pay to Lender a surcharge in an amount which would
result in Lender being made whole (on a present value basis) for the actual or
imputed funding losses (including without limitation any loss, cost or expense
incurred by reason of obtaining, liquidating or employing other funds acquired
by Lender to fund or maintain the fixed rate balance being prepaid) incurred by
Lender as a result thereof.  Such surcharges will be calculated in accordance
with methodology established by Lender (a copy of which will be made available
to CGI upon request and shall be conclusive absent manifest error).

                                       5
<PAGE>
 
     SECTION 2.7  COMPUTATION OF INTEREST.  Interest on all outstanding balances
on all Supplements shall be computed on the basis of a year consisting of 365
days and the actual number of days elapsed. In computing interest, the day of
Advance shall be included and the day of repayment shall be excluded.

     SECTION 2.8  SECURED GUARANTEE.  All of the obligations of CGI hereunder,
including without limitation CGI's obligations to repay any and all Advances
hereunder and under any Supplement hereto as and when any repayment is due, 
to make payments under Sections 2.3 or 2.5 hereof or to comply with all 
non-monetary covenants hereof, shall have the continuing and unlimited Guarantee
(the "Guarantee") of Holdings, secured by a first priority security interest in
all of its property other than the CG Member stock, but including without
limitation a pledge of Holdings' interests in the stock of CGI (the "Holdings
Pledge"). Further, as security for LLC's obligations under any Supplement
hereto, CG Member shall pledge (the "CG Member Pledge") to Lender all of its
right, title and interest in and to 100% of the membership interests in LLC..

Supplement to make any Advance to CGI hereunder is subject to the condition that
no Event of Default or event which with the giving of notice and/or the passage
of time would become an Event of Default hereunder (a "Potential Default"),
shall have occurred and is continuing.

accrued interest thereon, and all other amounts payable under this MLA, all

Upon such a declaration, the unpaid principal balance of the loans and all such
other amounts shall become immediately due and payable, without protest,
presentment, demand, or further notice of any kind, all of which are hereby
expressly waived by CGI.

     SECTION 9.2  ENFORCEMENT.  Lender may proceed to protect, exercise, and
enforce such rights and remedies as may be provided by this MLA, any other Loan
Document or under Law. Each and every one of such rights and remedies shall be
cumulative and may be exercised from time to time,

                                      15
<PAGE>
 
and no failure on the part of Lender to exercise, and no delay in exercising,
any right or remedy shall operate as a waiver thereof, and no single or partial
exercise of any right or remedy shall preclude any other or future exercise
thereof, or the exercise of any other right. Without limiting the foregoing,
Lender may hold and/or set off and apply against CGI's obligations to Lender the
proceeds of any stock in Lender, any cash collateral held by Lender, or any
balances held by Lender for the CGI's account (whether or not such balances are
then due).

     SECTION 9.3  APPOINTMENT OF RECEIVER.  The Lender shall be entitled to
apply for and obtain, without notice and upon ex parte application, the
appointment of a receiver for the Collateral without regard to CGI's financial
condition or solvency, the adequacy of the Collateral to secure the payment of
the Advances, or the performance of the Loan Documents, or the existence of any
waste to the Collateral. The receiver so appointed shall have all the powers
and authority usually held by receivers and reasonably necessary to accomplish
the purposes herein stated, including without limitation the following: (a) to
take charge of the Collateral and any and all personal property used therewith,
including, but not limited to, rental payments, lease payments, security
deposits, records, contracts, leases, and fixtures used or associated therewith,
if any; (b) maintain and protect the Collateral; (c) pay debts secured by the
Collateral to the extent appropriate, arrange and pay for appropriate insurance
for the receivership property; (d) deposit all sums received in a bank in the
name of the receiver, as receiver, and make payments as required; (e) account to
the court for all sums received, expenditures made and debt service paid; (f)
report to the court from time to time; (g) to the extent Lender advances funds
pursuant to the Loan Documents, if it elects to do so, or from other funds that
may become available, to complete the construction of, repair and maintain
improvements located on the Collateral in the event that the receiver determines
that such completion, repair and maintenance is appropriate and with said
amounts so disbursed to be considered as an additional indebtedness to CGI and
secured by the Mortgage; (h) to borrow funds from Lender or other parties, under
such terms that the receiver determines are reasonable, to the extent that the
receiver determines such funds are necessary for the completion, repair or
maintenance of the Collateral. In case of such borrowing, the receiver may issue
a receivership certificate to the Lender which receivership certificate shall
constitute a lien against the Collateral which is senior and prior to any and
all other liens; (i) to ratify, confirm, renegotiate, and hold all leases,
contracts, or other agreements related to the sale or operation of the
Collateral and to sell said Collateral on such terms and conditions as the
receiver deems appropriate; (j) to use rents and receipts from the Collateral
and from such funds as may be advanced by Lender or other parties for payment of
expenses of the receivership and of the Collateral; (k) to enter into contracts
with third parties to accomplish any of the powers of the receivership,
including hiring; (l) to do any and all acts necessary and convenient or
incidental to the foregoing; (m) to lease or rent the Collateral, if deemed
advisable by the receiver on such terms as are customary; (n) to sell the
Collateral or any portion thereof, in its present condition or upon completion
of construction, upon terms that are customary, and to issue as appropriate any
receiver's certificate and to report to the court as appropriate on the status
of the completion of construction and sale. The receiver shall supply the court
a report detailing the status of any sale of the subject property and
disposition of all sale proceeds; and (o) if the receiver deems appropriate, the
receiver may make changes in the plans and specifications, work, or materials as
it may deem appropriate, and to enter into, modify or terminate any contractual
arrangements as deemed appropriate.

     SECTION 9.4  APPLICATION OF FUNDS.  Lender will apply all payments received
by it to CGI's obligations to Lender first to costs (including Lender's
reasonable attorney fees), then to interest, and then to principal, and any
remaining sums to be paid to other Persons as their interests may appear.

     SECTION 9.5  DEFAULT INTEREST RATE.  In addition to the rights and remedies
set forth above: (i) if CGI fails to purchase any stock in Lender when required,
subject to Sections 2.3 or 2.5 hereof, or fails to make any payment to Lender
when due, then at Lender's option in each instance, such obligation or payment
shall bear interest at four percent (4%) per annum in excess of the applicable
interest rate; and (ii) after the maturity of any loan, whether by reason of
acceleration or otherwise, the unpaid balance of the loan shall automatically
bear interest at four percent (4%) per annum in excess of the rates that would
otherwise be in effect on such loan. All interest provided for herein shall be
payable on demand and shall be calculated from the date such payment was due to
the date paid on the basis of a year consisting of 365 days.

negligence or willful misconduct of the Person to be indemnified.

     SECTION 10.11  LIMITATION OF LIABILITY.  Neither Lender nor any Affiliate,
officer, director, employee, attorney, agent or participant of Lender shall have
any liability with respect to, and CGI hereby waives, releases, and agrees not
to sue any of them upon, any claim for any special, indirect, incidental, or
consequential damages suffered or incurred by CGI in connection with, arising
out of, or in any way related to, the MLA or any of the other Loan Documents, or
any of the transactions contemplated by the MLA or any of the other Loan
Documents.  CGI hereby waives, releases, and agrees not to sue Lender or any of
Lender's Affiliates, officers, directors, employees, attorneys, agents, or
participants for punitive damages in respect of any claim in connection with,
arising out of, or in  way related to, the MLA or any of the other Loan
Documents, or any of the transactions contemplated by the MLA or any of the
other Loan Documents.

     SECTION 10.12  NO DUTY.  All attorneys, accountants, appraisers, and other
professional Persons and consultants retained by Lender shall have the right to
act exclusively in the interest of Lender and shall have no duty of disclosure,
duty of loyalty, duty of care, or other duty or obligation of any type or nature
whatsoever to CGI or any of CGI's shareholders or any other Person.

                                      19
<PAGE>
 
     SECTION 10.13  LENDER NOT FIDUCIARY.  The relationship between CGI and
Lender is solely that of debtor and creditor, and Lender has no fiduciary or
other special relationship with CGI, and no term or condition of any of the Loan
Documents shall be construed so as to deem the relationship between CGI and
Lender to be other than that of debtor and creditor.

     SECTION 10.14  EQUITABLE RELIEF.  CGI recognizes that in the event CGI
fails to pay, perform, observe, or discharge any or all of the obligations, any
remedy at law may prove to be inadequate relief to Lender. CGI therefore agrees
that Lender, if Lender so requests, shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages.

     SECTION 10.15  COUNTERPARTS.  The MLA may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same agreement.

     SECTION 10.16  CONSTRUCTION.  CGI and Lender acknowledge that each of them
has had the benefit of legal counsel of its own choice and has been afforded an
opportunity to review the MLA and the other Loan Documents with its legal
counsel and that the MLA and the other Loan Documents shall be construed as if
jointly drafted by CGI and Lender.

     SECTION 10.17  PATRONAGE WAIVER.  CGI hereby waives and relinquishes any
and all rights and privileges, directly or indirectly, to receive or be awarded
any patronage refunds or dividends from Lender with respect to any loans made
pursuant to the MLA and any Supplement thereto.  However, in the event of any
change in Lender's capitalization bylaws (referenced in Section 2.3 hereof) or
capital adequacy law, rule or regulation (referenced in Section 2.5 hereof)
which would require CGI to increase its capitalization of Lender, CGI may be
entitled to participate in Lender's patronage program as it exists at the time,
to the extent any patronage payments are authorized by Lender's Board of
Directors.

     SECTION 10.18  USURY PREEMPTION.  Pursuant to 12 U.S.C. (S) 2205, interest
rates on loans made by Lender are not subject to any interest rate limitation
imposed by any state constitution or statute or other Laws, such limitations
being specifically preempted by Federal Law.

     SECTION 10.19  WAIVER OF JURY TRIAL.  TO THE FULLEST EXTENT PERMITTED BY

                      COLORADO GREENHOUSE HOLDINGS, INC.

                              FOR THE BENEFIT OF

                COLORADO SPRINGS PRODUCTION CREDIT ASSOCIATION


                                     DATED
                                     AS OF

                              JANUARY  24, 1997.



- --------------------------------------------------------------------------------
<PAGE>
 
                    SECURED CONTINUING GUARANTEE OF PAYMENT

     THIS GUARANTEE OF PAYMENT (this "Guarantee") is executed as of the 24th day
of January, 1997 by Colorado Greenhouse Holdings, Inc. (hereinafter referred
to as the "Guarantor") in favor of Colorado Springs Production Credit
Association (hereinafter referred to as "Lender").

                                  BACKGROUND

     Colorado Greenhouse, Inc. (the "Borrower") has obtained or may desire at
some point in time and/or from time to time to obtain loans, advances and other
financial accommodations from Lender. Owing to Borrower's financial condition
and/or other factors, Lender is not willing to extend or continue to extend
credit to the Borrower without the guarantee of the Guarantor. The Borrower is a
wholly-owned subsidiary of the Guarantor and the Guarantor has a financial
interest in the Borrower and is expecting to benefit from such credit, and
therefore the Guarantor is willing to furnish that guarantee in order to induce
Lender to extend or to continue to extend credit to the Borrower.

     NOW, THEREFORE, in order to induce Lender to extend credit to the Borrower
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Guarantor agrees as follows:

     SECTION 1  GUARANTEE.  The Guarantor hereby unconditionally and irrevocably
guarantees to Lender the punctual payment when due, whether at stated maturity,
by acceleration or otherwise, of all indebtedness, obligations and liabilities,
including without limitation all non-monetary covenants and other obligations,
of the Borrower to Lender, whether now existing or hereafter incurred, including
but not limited to those under or arising out of or in connection with any
loans, advances, acceptances, letters of credit, indemnities, foreign exchange
contracts or any other kind of contract or agreement under which the Borrower
may be indebted to Lender in any manner, whether for principal, inter est, fees,
surcharges, expenses or otherwise. For ease of reference: (i) all such
indebtedness, obligations and liabilities shall hereinafter be collectively
referred to as the "Guaranteed Obligations"; and (ii) all instruments, documents
and agreements evidencing or relating to the Guaranteed Obligations (including
all loan agreements, promissory notes, reimbursement agreements, security
agreements, mortgages and deeds of trust) shall hereinafter collectively be
referred to as the "Loan Documents."

     SECTION 2  SECURITY AGREEMENT.  To secure the payment or performance of all
Guaranteed Obligations, the hereby grants to Lender a continuing security
interest in and to the following property and interests in property of the
Guarantor, whether now owned or existing or hereafter acquired or arising and
wheresoever located: all accounts, inventory, equipment, fixtures, farm
products, general intangibles, chattel paper, instruments, documents,
intellectual property, and all accessions to, substitutions for, and all
replacements, products and proceeds of the foregoing, all books and records
(including without limitation customer lists, credit files, computer programs,
printouts, data whether stored electronically or otherwise, and other computer
materials and records) pertaining to the foregoing, and all insurance policies
insuring the above collateral. Without limiting any of the foregoing, Guarantor
also (i) grants to Lender a continuing security interest in and to and a pledge
of all its interests in (as more specifically set forth in the "Pledge
Agreement" of even date herewith) the Guarantor's interests in Borrower, and
(ii) shall cause CG Member, Inc. ("CG Member"), a wholly-owned subsidiary of
Guarantor, also to grant to Lender a pledge and security interest in all its
interest in its subsidiary, Colorado Greenhouse, LLC (the "LLC"). All of the
property and interests of the Guarantor described


<PAGE>
 
in this Section 2 (including, without limitation, the Guarantor's interest in
the Borrower) and CG Member's interest in the LLC shall hereinafter be referred
to as the "Collateral."

     SECTION 3  GUARANTY OF PAYMENT; WAIVER OF DEFENSES, ETC.  This Guarantee is
a guarantee of payment and not of collection, and of performance of Borrower's
obligations to Lender. The Guarantor acknowledges and agrees that this Guarantee
is an absolute and independent obligation of the Guarantor and therefore waives
any right to require that any action be brought against the Borrower, another
guarantor or any other Person or entity which is liable for all or any part of
the Guaranteed Obligations, or to require that resort be had at any time to any
security for the Guaranteed Obligations or to any right of setoff or similar
right. The Guarantor's obligations hereunder shall be payable on demand and
shall be absolute and unconditional irrespective of (and the Guarantor hereby
expressly waives any defense or claim of discharge based on): (i) the alteration
or modification from time to time (whether material or otherwise); (ii) the
waiver by Lender of the Borrower's compliance with any of the terms and
conditions of the Loan Documents; (iii) the forbearance by Lender from
exercising any right or remedy it may have under the Loan Documents or under
law; (iv) any inability, failure, neglect or omission to obtain, perfect,
maintain, enforce, or realize upon any Collateral for the Guaranteed
Obligations, or to pursue or obtain any deficiency judgment against the Borrower
following any foreclosure of any security interest, mortgage or deed of trust;
(v) the loss or impairment of any Collateral, the subordination or release of
Lender's lien thereon, or the sale, pledge, surrender, exchange or substitution
of any Collateral; (vi) Lender releasing, waiving, discharging, or modifying the
obligations of one or more other guarantors (whether a party hereto or to a
separate agreement with Lender); (vii) the acceptance by Lender of any partial
payment on the Guaranteed Obligations or any Collateral therefor, or Lender
settling, subordinating, compromising, discharging, or releasing the Guaranteed
Obligations or any Collateral therefor; (viii) the unenforceability of the loan
Documents; (ix) any defenses or counterclaims assertable by the Borrower,
including any defense or counterclaim based on failure of consideration, fraud,
statute of frauds, bankruptcy, statute of limitations, lender liability, and
accord and satisfaction; (x) any setoff, counterclaim, recoupment or similar
right assertable by the Borrower, the Guarantor, or other guarantor (whether a
party hereto or to a separate guarantee); or (xi) any other circumstance which
constitutes a legal or equitable discharge of a guarantor or surety. This
Guarantee shall continue in full force and effect until five business days after
written notice of termination shall have been received by Lender.
Notwithstanding the foregoing, such notice of termination shall not be effective
as to any Guaranteed Obligations: (1) existing prior to the effective date of
termination; (2) arising thereafter pursuant to any commitment to extend credit
entered into prior to the effective date of such notice (regardless of whether
Lender has or from time to time acquires a right to suspend or terminate such
commitment owing to the occurrence of a default or otherwise); (3) any
extensions, renewals, or refinancing(s) of any Guaranteed Obligations referred
to in (1) or (2) above made before or after the effective date of termination;
and (4) interest, fees, expenses and other Guaranteed Obligations relating to
any of the foregoing. In addition, no such notice of termination shall in any
manner impair or alter Lender's rights or obligations hereunder with respect to
such Guaranteed Obligations (including under Sections 3 and 6 hereof) or affect
or impair the obligations of any other guarantor (whether a party hereto or to a
separate guarantee).

     SECTION 4  SUBORDINATION AND SUBROGATION.  The Guarantor hereby agrees that
all indebtedness and other obligations of the Borrower (now existing or
hereafter incurred) to the Guarantor are and shall be subordinated in right of
payment to the prior payment in full by the Borrower of its obligations to
Lender under the Loan Documents. During the existence of a default under the
Loan Documents, no payments by the Borrower shall be accepted by the Guarantor
with respect to such subordinated

                                       2
<PAGE>
 
obligations and, if any such payments are inadvertently received, the same shall
be held in trust and promptly turned over to Lender. The Guarantor hereby waives
all claims, rights or remedies that it may have at law or in equity (including,
without limitation, any law subrogating the Guarantor to the rights of Lender)
to seek contribution, indemnification, or any other form of reimbursement from
the Borrower, any other guarantor, or any other person or entity now or
hereafter primarily or secondarily liable for any obligations of the Guarantor
to Lender for any disbursement made by the Guarantor under or in connection with
this Guarantee. The Guarantor hereby stipulates and agrees that any such
disbursement made by the Guarantor shall be a contribution to the equity capital
of the Borrower.

     SECTION 5  RECOVERY OF PAYMENT.  If any payment received by Lender and
applied to the Guaranteed Obligations is subsequently set aside, recovered,
rescinded, or required to be returned for any reason (including, without
limitation, the bankruptcy, insolvency or reorganization of the Guarantor),
the Guaranteed Obligations to which such payment was applied shall for the
purposes of this Guarantee and all instruments or documents executed in
connection herewith or securing the Guarantor's obligations hereunder, be deemed
to have continued in existence, and this Guarantee shall be enforceable as to
such Guaranteed Obligations as fully as if such applications had never been
made.

     SECTION 6  INFORMATION REGARDING BORROWER; WAIVER OF NOTICES, ETC.  The
Guarantor assumes responsibility for keeping fully informed of the financial
condition of the Borrower, its liability hereunder and all other circumstances
affecting the Borrower's ability to pay and perform the Guaranteed Obligations.
The Guarantor agrees that Lender shall have no duty to report to or notify the
Guarantor of: (i) any information which Lender shall receive about the financial
condition of the Borrower (including adverse matters); (ii) the Borrower's
performance under the Loan Documents (including nonpayment or the occurrence of
any other default); (iii) any circumstances bearing on the Borrower's ability
to perform the Guaranteed Obligations; (iv) any increases in the amount of the
Guaranteed Obligations or any renewals, extension or refinancing(s) of any
Guaranteed Obligation; (v) any actions taken by Lender or the Borrower under any
Loan Document; (vi) any matters relating to another guarantor; (vii) any matter
set forth in Section 3 hereof; or (viii) any other matter relating to the
Guaranteed Obligations; and the Guarantor hereby expressly and unconditionally
waives any defense or claim of discharge based on the failure of Lender to
report to notify the Guarantor of any such information. In addition, the
Guarantor hereby acknowledges that it has entered into this Guarantee based
upon its own independent knowledge of or investigation in to the affairs of the
Borrower and any other guarantor (whether a party hereto or to a separate
guarantee) and has not relied in any respect on Lender or any officers,
employees, or agents thereof.

     SECTION 7  REPRESENTATIONS AND WARRANTIES.  The Guarantor hereby represents

agreement to which the Guarantor is a party or by which it or any of its
property may be bound or affected, or with any provision of its certificate of

through any legal proceedings, Maker agrees to pay all costs, expenses and

made on account of the principal hereof and interest accruing hereon, which
records shall be prima facie evidence as to the outstanding principal amount of

    by Colorado Greenhouse); provided, however, that this subordination shall
    not affect, postpone or diminish in any way the priority of the Landlord's
    reversionary interest in the "Facility" (as such term is defined under

    Tenant under the Greenhouse Lease, or to inhibit or impair in any way the

    Facility at any time if Farm Credit notifies the Project Parties that such
    immediate access is necessary to prevent the value of the crops from being
    impaired given their perishable nature and the controlled conditions under

     if mailed, when duly deposited in the mails. Failure of a Project Party to
     provide such notice to Farm Credit shall not constitute a breach of this
     Agreement, and Farm Credit agrees that Project Parties shall have no
     liability to Farm Credit for such failure; however, no claim of rescission
     or termination of the Project Documents by the applicable Project Party
     shall be binding upon Farm Credit without such notice.

9.   Each Project Party acknowledges and agrees for the benefit of Farm Credit
     that as between itself and Colorado Greenhouse, Colorado Greenhouse owns
     all crops on the Premises planted by Colorado Greenhouse prior to the
     termination of the Management Agreement and all crops harvested therefrom.

10.  Each Project Party agrees that the making of any distributions by Colorado
     Greenhouse to its members after the payment of all of its other obligations
     then due (including, without limitation, all payments due under the
     Management Agreement), regardless of the purposes for which such funds are
     used by the members of Colorado Greenhouse (including the construction and
     operation of any new greenhouses), shall not cause Colorado Greenhouse to
     be in violation of Section 3.3(a) of the Management Agreement.

11.  This Agreement shall be governed by and construed in accordance with the
     laws of the State of New York. This Agreement shall be binding upon the
     Project Parties and their successors and assigns and is executed for the
     benefit of Farm Credit and its successors and assigns.

12.  This Agreement shall continue in full force and effect so long as any
     portion of the Obligations remain due and owing and CGI has any commitment
     or obligation to Colorado Greenhouse under the Line of Credit Agreement.

13.  This Agreement represents the entire agreement of the parties with respect
     to the subject matter hereof.

                           CONSENT AND SUBORDINATION

                                   RECITALS:
                                   --------

     A.   Landlord and Tenant have entered into that certain Amended and

Greenhouse Lease) to Tenant.

     B.   Landlord has executed that certain Construction and Term Loan Deed of
Trust, Security Agreement and Assignment of Rents dated as of June 30, 1992,
in favor of The Prudential Insurance Company of America and Credit Suisse
(collectively, the "Lenders") (as the same has been or may hereafter be amended,

on, among other property, the Premises.

     C.   Tenant and Colorado Greenhouse LLC, a Colorado limited liability
company ("Colorado Greenhouse") have entered into that certain Greenhouse

Colorado Greenhouse has agreed to operate and manage the Premises.

     D.   Farm Credit and Colorado Greenhouse, Inc. ("CGI"), an affiliate of
Colorado Greenhouse, have entered into that certain Master Loan Agreement dated
as of January 24, 1997 (as the same may be amended, the "MLA"). As allowed under
the MLA, CGI has entered into a Line of Credit Agreement (the "Line of Credit
Agreement") with Colorado Greenhouse, providing for a line of credit in the
aggregate principal amount of up to $1,500,000, pursuant to which CGI may make
loans to Colorado Greenhouse.

     E.   In order to secure the obligations arising in connection with the Line
of Credit Agreement (the "Obligations"), Colorado Greenhouse has entered into a
Security Agreement (as the same may be amended, the "Security Agreement") with
CGI dated as of January 24, 1997, pursuant to which Colorado Greenhouse granted
to CGI security interests (the "Security Interests") in all of its right, title
and interest in and to all crops now or hereafter planted, growing or stored on
the Premises (as defined in the Greenhouse Lease, and any such crops, herein,

harvesting and packaging of such Crops of the type described on Exhibit A
attached hereto, which are now (or may hereafter be) stored on the Premises (the

Collateral").

     F.  In order to secure its obligations under the MLA, CGI has granted a
security interest (the "Chattel Security Interest") in favor of Farm Credit in

     G.  In order to induce (i) CGI to extend credit to Colorado Greenhouse and
(ii) Farm Credit to extend credit to CGI, Landlord and Tenant (together, the
"Project Parties") desire to enter into this Agreement for the benefit of Farm
Credit.

     NOW THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which have hereby been
acknowledged, the parties hereto agree as follows:

      1.   Landlord acknowledges having been informed of (i) Colorado
           Greenhouse's execution and delivery of the Line of Credit Agreement
           and the Security Agreement, and of the consummation of the
           transactions contemplated thereby and (ii) CGI's execution and
           delivery of the MLA and the granting of the Chattel Security
           Interest.

      2.   Tenant hereby consents to Colorado Greenhouse's execution and
           delivery of the Line of Credit Agreement and the Security Agreement
           and to the consummation of the transactions contemplated thereby and
           agrees that such execution, delivery and consummation do not conflict
           with, result in a breach of or constitute a default under any Project
           Documents to which it is a party.

      3.   Each Project Party represents and warrants to Farm Credit with
           respect to itself and the Project Documents to which it is a party
           that:
 
           (a)   No default, event of default or event that would permit the
                 termination of a Project Document exists under the Project
                 Documents to which it is a party;

           (b)   The Project Documents to which it is a party constitutes its
                 legal, valid and binding obligation enforceable against it in
                 accordance with their respective terms except as limited by
                 bankruptcy, insolvency or other laws of general application
                 relating to the enforcement of creditors rights; and

           (c)   None of the Project Documents to which it is a party has
                 terminated.
  

      4.   Each Project Party hereby subordinates, makes junior, second and
           inferior to the Security Interests covering the CGI Collateral, any
           security interests, liens, and other rights, titles and interests
           (including without limitation, any security interest, lien or other
           right covering the CGI Collateral created in any Project Documents)

                                       2
<PAGE>
 
     which it now has or may hereafter acquire with respect to the CGI
     Collateral (regardless of whether the CGI Collateral is now owned or
     hereafter acquired by Colorado Greenhouse); provided, however, that this
     subordination shall not affect, postpone or diminish in any way the
     priority of the Landlord's reversionary interest in the "Facility" (as such
     term is defined under Section 2.1 of the Greenhouse Lease) which has been
     leased and demised to Tenant under the Greenhouse Lease, or to inhibit or
     impair in any way the exercise by Landlord of any rights and remedies
     available to Landlord in the event of a Default (defined in the Greenhouse
     Lease to be a breach extending beyond any applicable grace or cure period)
     by Tenant under the Greenhouse Lease.

5.   Farm Credit through its authorized representatives or agents, may during
     normal business hours and upon 24 hours advance notice enter upon the
     Premises (as defined in the Greenhouse Lease) at any time and from time to
     time for the purposes of inspecting and caring for the CGI Collateral and,
     after the occurrence of an Event of Default under the Line of Credit
     Agreement, for the purpose of removing or conducting a sale or sales of any
     or all of the CGI Collateral. Farm Credit shall have no obligation or
     liability to Colorado Greenhouse or any Project Party in connection with
     the foregoing actions except, however, that Farm Credit shall promptly
     repair any damage to the Premises (as defined in the Greenhouse Lease)
     caused by such removal, sale or inspection and that Farm Credit shall be
     liable to a Project Party that has been damaged as a result of the acts and
     omissions of Farm Credit's employees or agents in connection with such
     removal, sale or inspection.

6.   The Project Parties shall permit Farm Credit immediate access to the
     Facility at any time if Farm Credit notifies the Project Parties that such
     immediate access is necessary to prevent the value of the crops from being
     impaired given their perishable nature and the controlled conditions under
     which they are grown, harvested and stored.

7.   Farm Credit's right to enter and remain upon the Premises and to remove
     therefrom the CGI Collateral as hereinbefore set forth shall terminate on
     the date which is the later of:

     (a) the date 60 days after the Lenders have (i) taken possession of the
     Premises and (ii) provided Farm Credit written notice of such termination,
     or

     (b) the date 30 days after the completion of the harvest of all crops which
     were planted on the Premises prior to the date Colorado Greenhouse's right
     to possession of the Premises terminated.

8.   Each Project Party agrees to give Farm Credit written notice prior to or
     simultaneously with its exercise of any of its rights or remedies, or any
     other parties' rights or remedies of which such Project Party has
     knowledge, arising



                                       3
<PAGE>
 
     under any Project Documents as a result of a default, event of default or
     other event that would entitle a party to terminate any Project Document.
     Any notice or other communication required or permitted to be given under
     this Agreement to Farm Credit must be in writing and delivered in person or
     mailed by registered or certified mail, return receipt requested, postage
     prepaid to Farm Credit at this following address:

            3625 Citadel Dr. S.

            Colorado Springs, CO 80932-9290

     or such other address as shall be set forth in a notice from the
     appropriate party given in compliance with this paragraph. Any such notice
     or other communication shall be deemed given when delivering in person, or,
     if mailed, when duly deposited in the mails. Failure of a Project Party to
     provide such notice to Farm Credit shall not constitute a breach of this
     Agreement, and Farm Credit agrees that Project Parties shall have no
     liability to Farm Credit for such failure; however, no claim of rescission
     or termination of the Project Documents by the applicable Project Party
     shall be binding upon Farm Credit without such notice.

9.   Each Project Party acknowledges and agrees for the benefit of Farm Credit
     that as between itself and Colorado Greenhouse, Colorado Greenhouse owns
     all crops on the Premises planted by Colorado Greenhouse prior to the
     termination of the Management Agreement and all crops harvested therefrom.

10.  Each Project Party agrees that the making of any distributions by Colorado
     Greenhouse to its members after the payment of all of its other obligations
     then due (including, without limitation, all payments due under the
     Management Agreement), regardless of the purposes for which such funds are
     used by the members of Colorado Greenhouse (including the construction and
     operation of any new greenhouses), shall not cause Colorado Greenhouse to
     be in violation of Section 3.3(a) of the Management Agreement.

11.  This Agreement shall be governed by and construed in accordance with the
     laws of the State of New York. This Agreement shall be binding upon the
     Project Parties and their successors and assigns and is executed for the
     benefit of Farm Credit and its successors and assigns.

12.  This Agreement shall continue in full force and effect so long as any
     portion of the Obligations remain due and owing and CGI has any commitment
     or obligation to Colorado Greenhouse under the Line of Credit Agreement.

13.  This Agreement represents the entire agreement of the parties with respect
     to the subject matter hereof.

     G.  In order to induce (i) CGI to extend credit to Colorado Greenhouse and
(ii) Farm Credit to extend credit to CGI, Landlord and Tenant (together, the

Credit.

     NOW THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which have hereby been
acknowledged, the parties hereto agree as follows:

     1.  Landlord acknowledges having been informed of (i) Colorado Greenhouse's
         execution and delivery of the Line of Credit Agreement and the Security
         Agreement, and of the consummation of the transactions contemplated
         thereby and (ii) CGI's execution and delivery of the MLA and the
         granting of the Chattel Security Interest.

     2.  Tenant hereby consents to Colorado Greenhouse's execution and delivery
         of the Line of Credit Agreement and the Security Agreement and to the
         consummation of the transactions contemplated thereby and agrees that
         such execution, delivery and consummation do not conflict with, result
         in a breach of or constitute a default under any Project Documents to
         which it is a party.

     3.  Each Project Party represents and warrants to Farm Credit with respect
         to itself and the Project Documents to which it is a party that:
  
         (a) No default, event of default or event that would permit the
         termination of a Project Document exists under the Project Documents to
         which it is a party;

         (b) The Project Documents to which it is a party constitutes its legal,
         valid and binding obligation enforceable against it in accordance with
         their respective terms except as limited by bankruptcy, insolvency or
         other laws of general application relating to the enforcement of
         creditors rights; and

         (c) None of the Project Documents to which it is a party has

     4.  Each Project Party hereby subordinates, makes junior, second and
         inferior to the Security Interests covering the CGI Collateral, any
         security interests, liens, and other rights, titles and interests
         (including without limitation, any security interest, lien or other
         right covering the CGI Collateral created in any Project Documents)
         which it now has or may hereafter acquire with respect to the CGI
         Collateral (regardless of whether the CGI Collateral is now owned or
         hereafter acquired by Colorado Greenhouse); provided, however, that
         this subordination shall not affect, postpone or diminish in any way
         the priority of the Landlord's reversionary interest in the "Facility"
         (as such term is defined under Section 2.1 of the Greenhouse Lease)
         which has been leased and demised to Tenant under the Greenhouse Lease,
         or to inhibit or impair in any way the exercise by Landlord of any
         rights and remedies available to Landlord in the event of a Default
         (defined in the Greenhouse Lease to be a breach extending beyond any
         applicable grace or cure period) by Tenant under the Greenhouse Lease.

     5.  Farm Credit through its authorized representatives or agents, may
         during normal business hours and upon 24 hours advance notice enter
         upon the Premises (as defined in the Greenhouse Lease) at any time and
         from time to time for the purposes of inspecting and caring for the CGI
         Collateral and, after the occurrence of an Event of Default under the
         Line of Credit Agreement, for the purpose of removing or conducting a
         sale or sales of any or all of the CGI Collateral. Farm Credit shall
         have no obligation or liability to Colorado Greenhouse or any Project
         Party in connection with the foregoing actions except, however, that
         Farm Credit shall promptly repair any damage to the Premises (as
         defined in the Greenhouse Lease) caused by such removal, sale or
         inspection and that Farm Credit shall be liable to a Project Party that
         has been damaged as a result of the acts and omissions of Farm Credit's
         employees or agents in connection with such removal, sale or
         inspection.

     6.  The Project Parties shall permit Farm Credit immediate access to the
         Facility at any time if Farm Credit notifies the Project Parties that
         such immediate access is necessary to prevent the value of the crops
         from being impaired given their perishable nature and the controlled
         conditions under which they are grown, harvested and stored.

     7.  Farm Credit's right to enter and remain upon the Premises and to remove
         therefrom the CGI Collateral as hereinbefore set forth shall terminate
         on the date which is the later of:

         (a)  the date 60 days after the Lenders have (i) taken possession of
         the Premises and (ii) provided Farm Credit written notice of such
         termination, or

         (b) the date 30 days after the completion of the harvest of all crops
         which were planted on the Premises prior to the date Colorado
         Greenhouse's right to possession of the Premises terminated.


                                       3

     8.  Each Project Party agrees to give Farm Credit written notice prior to
         or simultaneously with its exercise of any of its rights or remedies,
         or any other parties' rights or remedies of which such Project Party
         has knowledge, arising under any Project Documents as a result of a
         default, event of default or other event that would entitle a party to
         terminate any Project Document. Any notice or other communication
         required or permitted to be given under this Agreement to Farm Credit
         must be in writing and delivered in person or mailed by registered or
         certified mail, return receipt requested, postage prepaid to Farm
         Credit at this following address:

         or such other address as shall be set forth in a notice from the
         appropriate party given in compliance with this paragraph. Any such
         notice or other communication shall be deemed given when delivering in
         person, or, if mailed, when duly deposited in the mails. Failure of a
         Project Party to provide such notice to Farm Credit shall not
         constitute a breach of this Agreement, and Farm Credit agrees that
         Project Parties shall have no liability to Farm Credit for such
         failure; however, no claim of rescission or termination of the Project
         Documents by the applicable Project Party shall be binding upon Farm
         Credit without such notice.

     9.  Each Project Party acknowledges and agrees for the benefit of Farm
         Credit that as between itself and Colorado Greenhouse, Colorado
         Greenhouse owns all Crops on the Premises planted by Colorado
         Greenhouse prior to the termination of the Management Agreement and all
         crops harvested therefrom.

     10. Each Project Party agrees that the making of any distributions by
         Colorado Greenhouse to its members after the payment of all of its
         other obligations then due (including, without limitation, all payments
         due under the Management Agreement), regardless of the purposes for
         which such funds are used by the members of Colorado Greenhouse
         (including the construction and operation of any new greenhouses),
         shall not cause Colorado Greenhouse to be in violation of Section
         3.3(a) of the Management Agreement.

     11. This Agreement shall be governed by and construed in accordance with
         the laws of the State of New York. This Agreement shall be binding upon
         the Project Parties and their successors and assigns and is executed
         for the benefit of Farm Credit and its successors and assigns.

     12. This Agreement shall continue in full force and effect so long as any
         portion of the Obligations remain due and owing and CGI has any
         commitment or obligation to Colorado Greenhouse under the Line of
         Credit Agreement.

     8.  Each Project Party agrees to give Farm Credit written notice prior to
         or simultaneously with its exercise of any of its rights or remedies,
         or any other parties' rights or remedies of which such Project Party
         has knowledge, arising under any Project Documents as a result of a
         default, event of default or other event that would entitle a party to
         terminate any Project Document. Any notice or

         Credit without such notice.

     9.  Each Project Party acknowledges and agrees for the benefit of Farm
         Credit that as between itself and Colorado Greenhouse, Colorado
         Greenhouse owns all crops on the Premises planted by Colorado
         Greenhouse prior to the termination of the Management Agreement and all

     Re:  Colorado Power Partners, Partners, Brush Greenhouse Partners and
          Colorado Greenhouse LLC

Ladies and Gentlemen:

     Reference is made to that certain Construction and Term Loan Deed of Trust,
Security Agreement and Assignment of Rents dated as of June 30, 1993 (as may be
amended, the "Deed of Trust") from Colorado Power Partners ("CPP") in favor of
the undersigned (collectively, the "Lenders"). The Deed of Trust was created
pursuant to the terms of the Construction and Term Loan Agreement among CPP and
the Lenders, which document provided for the advancement of funds from the
Lenders to CPP for the purposes of constructing a cogeneration facility, which
includes a commercial greenhouse facility, located in Brush, Colorado (the
"Facility").

     It is our understanding that:

     (a)  CPP has leased the greenhouse component of the Facility to Brush
          Greenhouse Partners ("BGP") pursuant to that certain Cogeneration and
          Greenhouse Lease Agreement dated as of June 8, 1989 (the "Greenhouse
          Lease");

     (b)  BGP has entered into a Greenhouse Operation and Management Agreement
          ("O&M Agreement") dated as of December 29, 1994 with Colorado
          Greenhouse LLC ("Colorado Greenhouse"); and

     (c)  Colorado Greenhouse has entered into a Line of Credit Agreement
          (providing for a line of credit in the aggregate principal amount of
          up to $1,500,000) and a Security Agreement (together, the "Loan
          Documents"), each dated as of January 24, 1997, with Colorado
          Greenhouse, Inc. ("CGI"), which is an affiliate of Colorado
          Greenhouse;

     (d)  CPP and BGP have executed that certain Consent and Subordination (the
          "Consent") dated as of January 24, 1997, in favor of Colorado Springs

          Production Credit Association ("Farm Credit"), a copy of which is
          attached hereto as Exhibit H.

     You have informed us that you are entering into a loan transaction (the
"Loan") with CGI evidenced by Master Loan Agreement (the "Master Loan
Agreement") dated as of January 24, 1997, which contemplates the execution of a
Security Agreement (the "Security Agreement") and an Assignment of Loan
Documents (the "Assignment"), copies of which is attached hereto as Exhibits C-1
and C-2, pursuant to which CGI will grant to Farm Credit a security interest in
the Loan Documents. You have also informed us that the Loan Documents, copies of
which are attached hereto as Exhibits D and E, will grant to CGI security
interests in all of Colorado Greenhouse's right, title and interest in and to
all crops now or hereafter planted, growing or stored on the Premises (as
defined in the Greenhouse Lease, and any such crops, herein the "Crops"), all
material and supplies utilized in the planting, growing, harvesting and
packaging of such Crops, of the type described on Exhibit A attached hereto,
which are now (or may hereafter be) stored on the Premises (the "Supplies"), 
the equipment described on Exhibit B attached hereto, which is or may be located
on the Premises (the "Equipment") and all the other property owned by Colorado
Greenhouse described therein as the Collateral (such property herein referred to
as the "CGI Collateral").

     We acknowledge for your benefit that Colorado Greenhouse has not granted
any liens or security interests to us or for our benefit, and we disclaim any
interest in any of the Crops, Supplies or Equipment.

     We also agree for the benefit of Farm Credit that we will not claim any
crops which are now or may hereafter be planted on the Premises prior to the
termination of Colorado Greenhouse's right to possession of the Premises and any
crops now or hereafter stored on the Premises by Colorado Greenhouse as being
part of the Facility encumbered by the Deed of Trust.

     As long as either CPP or BGP is entitled to possession of the Facility, the
undersigned Lenders agree not to interfere with any rights Farm Credit has under
the Consent.

     Lenders agree that after they have or their authorized representative has
obtained possession of the Facility under the rights set forth in the Deed of
Trust or otherwise, Farm Credit may from time to time, through its authorized
representative, during normal business hours and with 24 hours written notice to
the Lenders at the address set forth herein, enter the Premises for the purposes
of caring for the Crops and removing the Crops, Supplies, Equipment and any
other property that is owned by Colorado

Greenhouse (as determined by reasonable and customary evidence thereof) which
constitutes CGI Collateral.

     After the Lenders or their authorized representatives have obtained
possession of the Facility under the rights set forth in the Deed of Trust or
otherwise, the Lenders shall permit Farm Credit immediate access to the Facility
at anytime if Farm Credit notifies the Lenders that such immediate access is
necessary to prevent the value of the Crops from being impaired given their
perishable nature and the controlled conditions under which they are grown,
harvested and stored.

     Farm Credit's right to enter and remain upon the Premises and to remove
therefrom the CGI Collateral as hereinbefore set forth shall terminate on the
date which is the later of:

     (a)  the date 60 days after the Lenders have (i) taken possession of the
          Facility and (ii) provided Farm Credit written notice of such
          termination; or

     (b)  the earlier of (i) the date 30 days after the completion of the
          harvest of all Crops which were planted on the Premises prior to the
          date Colorado Greenhouse's right to possession of the Premises
          terminated or (ii) 10 months after the date Colorado Greenhouse's
          right to possession of the Premises terminated.

     Farm Credit agrees to promptly and at its own expense repair any damages to
the Facility caused by either it or its authorized representatives while on the
Facility. In furtherance of the foregoing, Farm Credit shall indemnify and hold
the Lenders and their respective affiliates, officers, directors and agents
harmless from any loss, liability or damage incurred or suffered by any such
persons or entity as a direct or proximate result of the acts or omissions of
Farm Credit or its authorized representatives while Farm Credit or its
authorized representatives are present at the Facility.

     The Lenders acknowledge and accept that CPP and BGP have agreed that the
making of any distributions by Colorado Greenhouse to its members after the
payment of all of its other obligations then due (including, without limitation,
all payments due under the O&M Agreement), regardless of the purposes for which
such funds are used by the members of Colorado Greenhouse (including the
construction and operation of any new greenhouses), shall not cause Colorado
Greenhouse to be in violation of Section 3.3(a) of the O&M Agreement.

     This consent shall terminate and be of no further force and effect in the
event that Farm Credit shall agree to any amendment to or waive, or accept any
waiver of, (a) the provisions of Section 2(D) of the Pledge Agreement, dated as
of January 24, 1997 (the

Member") to Farm Credit, a copy of which is attached hereto as Exhibit F, or any
other provision of the Pledge Agreement if such amendment or waiver affects the 
application or effect of the provisions of Section 2(D) thereof or (b) the 
provisions of Section 2.2, 2.3 or 8.1 of the Colorado Greenhouse LLC Loan 
Supplement, dated as of January 24, 1997 (the "LLC Loan Supplement"), between 
Farm Credit and CGI, a copy of which is attached hereto as Exhibit G, or any 
other provision of the LLC Loan Supplement is such amendment or waiver affects 
the application or effect of the provisions of any such Section. This consent 
shall also terminate upon the termination of the LLC Loan Supplement. Finally, 
this consent is given based upon our understanding that the shares of CG Member 
have not been and will not be pledged to Farm Credit.

        Re:  Brush Cogeneration Partners, Brush Greenhouse Partners II, LLC and
             Colorado Greenhouse LLC

Ladies and Gentlemen:

        Reference is made to that certain Construction and Term Loan Deed of
Trust, Security Agreement and Assignment of Rents dated as of June 30, 1992, as
amended (the "Deed of Trust") from Brush Cogeneration Partners ("BCP") in favor
of the undersigned (collectively, the "Lenders"). The Deed of Trust was created
pursuant to the terms of the Construction and Term Loan Agreement among BCP and
the Lenders, which document provided for the advancement of funds from the
Lenders to BCP for the purposes of constructing a cogeneration facility, which
includes a commercial greenhouse facility, located in Brush, Colorado (the
"Facility").

        It is our understanding that:

        (a)  BCP has leased the greenhouse component of the Facility to Brush
             Greenhouse Partners II, LLC ("BGP II") pursuant to that certain
             Amended and Restated Cogeneration and Greenhouse Lease Agreement
             dated as of June 1, 1992 (as amended, the "Greenhouse Lease");

        (b)  BGP II has entered into a Greenhouse Operation and Management
             Agreement (the "O&M" Agreement") dated as of December 29, 1994 with
             Colorado Greenhouse LLC ("Colorado Greenhouse");

        (c)  Colorado Greenhouse has entered into a Line of Credit Agreement
             (providing for a line of credit in the aggregate principal amount
             of up to $1,500,000) and a Security Agreement (together, the "Loan
             Documents"), each dated as of January 24, 1997, with Colorado
             Greenhouse, Inc. ("CGI"), which is an affiliate of Colorado
             Greenhouse;
<PAGE>
 
Colorado Springs Production Credit Association

Page 2

     (d)  BCP and BGP 11 have executed that certain Consent and Subordination
          (the "Consent") dated as of January 24, 1997, in favor of Colorado
          Springs Production Credit Association ("Farm Credit"), a copy of which
          is attached hereto as Exhibit H.

     You have informed us that you are entering into a loan transaction (the
"Loan") with CGI evidenced by Master Loan Agreement (the "Master Loan
Agreement") dated as of January 24, 1997, which contemplates the execution of a
Security Agreement (the "Security Agreement") and an Assignment of Loan
Documents (the "Assignment"), copies of which are attached hereto as Exhibits 
C-1 and C-2, pursuant to which CGI will grant to Farm Credit a security interest
in the Loan Documents. You have also informed us that the Loan Documents, copies
of which are attached hereto as Exhibits D and E, will grant to CGI security
interests in all of Colorado Greenhouse's right, title and interest in and to
all crops now or hereafter planted, growing or stored on the Premises (as
defined in the Greenhouse Lease, and any such crops, herein the "Crops"), all
material and supplies utilized in the planting, growing, harvesting and
packaging of such Crops, of the type described on Exhibit A attached hereto,
which are now (or may hereafter be) stored on the Premises (the "Supplies"), the
equipment described on Exhibit B attached hereto, which is or may be located on
the Premises (the "Equipment") and all the other property owned by Colorado
Greenhouse described therein as the Collateral (such property herein referred to
as the "CGI Collateral").

     We acknowledge for your benefit that Colorado Greenhouse has not granted
any liens or security interests to us or for our benefit, and we disclaim any
interest in any of the Crops, Supplies or Equipment.

     We also agree for the benefit of Farm Credit that we will not claim any
crops which are now or may hereafter be planted on the Premises prior to the
termination of Colorado Greenhouse's right to possession of the Premises and any
crops now or hereafter stored on the Premises by Colorado Greenhouse as being
part of the Facility encumbered by the Deed of Trust.

     As long as either BCP or BGP II is entitled to possession of the Facility,
the undersigned Lenders agree not to interfere with any rights Farm Credit has
under the Consent.

     Lenders agree that after they have or their authorized representative has
obtained possession of the Facility under the rights set forth in the Deed of

Greenhouse (as determined by reasonable and customary evidence thereof) which
constitutes CGI Collateral.

     After the Lenders or their authorized representatives have obtained
possession of the Facility under the rights set forth in the Deed of Trust or
otherwise, the Lenders shall permit Farm Credit immediate access to the Facility
at any time if Farm Credit notifies the Lenders that such immediate access is
necessary to prevent the value of the Crops from being impaired given their
perishable nature and the controlled conditions under which they are grown,

     Farm Credit's right to enter and remain upon the Premises and to remove
therefrom the CGI Collateral as hereinbefore set forth shall terminate on the
date which is the later of:

     (a)  the date 60 days after the Lenders have (i) taken possession of the
          Facility and (ii) provided Farm Credit and CGI written notice of such
          termination; or

     (b)  the date 30 days after the completion of the harvest of all Crops
which were planted on the Premises prior to the date Colorado Greenhouse's right
to possession of the Premises terminated.

     Farm Credit agrees to promptly and at its own expense repair any damages to
the Facility caused by either it or its authorized representatives while on the
Facility. In furtherance of the foregoing, Farm Credit shall indemnify and hold
the Lenders and their respective affiliates, officers, directors and agents
harmless from any loss, liability or damage incurred or suffered by any such
persons or entity as a direct or proximate result of the acts or omissions of
Farm Credit or its authorized representatives while Farm Credit or its
authorized representatives are present at the Facility.

     The Lenders acknowledge and accept that BCP and BGP II have agreed that the
making of any distributions by Colorado Greenhouse to its members after the
payment of all of its other obligations then due (including, without limitation,
all payments due under the O&M Agreement), regardless of the purposes for which
such funds are used by the members of Colorado Greenhouse (including the
construction and operation of any new greenhouses), shall not cause Colorado
Greenhouse to be in violation of Section 3.3(a) of the O&M Agreement.

event that Farm Credit shall agree to any amendment to or waive, or accept any
waiver of, (a) the

Re:  Thermo Cogeneration Partnership, L.P., Rocky Mountain Produce LLC and
     Colorado Greenhouse LLC

Ladies and Gentlemen:

     Reference is made to that certain Construction and Term Loan Deed of Trust,
Security Agreement and Assignment of Rents dated as of April 7, 1993, as
amended (the "Deed of Trust") from Thermo Cogeneration Partnership, L.P.
("Thermo") in favor of the undersigned (collectively, the "Lenders"). The Deed
of Trust was created pursuant to the terms of the Construction and Term Loan
Agreement among Thermo and the Lenders, which document provided for the
advancement of funds from the Lenders to Thermo for the purposes of
constructing a cogeneration facility, which includes a commercial greenhouse
facility, located in Fort Lupton, Colorado (the "Facility").

     It is our understanding that:

     (a)  Thermo has leased the greenhouse component of the Facility to Rocky
          Mountain Produce LLC ("RMP") pursuant to that certain Thermal Supply
          Lease Agreement dated as of March 22, 1993 (as amended, the
          "Greenhouse Lease");

     (b)  RMP has entered into a Greenhouse Operation and Management Agreement
          ("O&M Agreement") dated as of December 29, 1994 with Colorado
          Greenhouse LLC ("Colorado Greenhouse");

     (c)  Colorado Greenhouse has entered into a Line of Credit Agreement
          (providing for a line of credit in the aggregate principal amount of
          up to $1,500,000) and a Security Agreement (together, the "Loan
          Documents"), each dated as of January 24, 1997, with Colorado
          Greenhouse, Inc. ("CGI"), which is an affiliate of Colorado
          Greenhouse;
<PAGE>
 
Colorado Springs Production Credit Association
January 28, 1997
Page 2

     (d)  Thermo and RMP have executed that certain Consent and Subordination
          (the "Consent") dated as of January 24, 1997, in favor of Colorado
          Springs Production Credit Association ("Farm Credit"), a copy of which
          is attached hereto as Exhibit H.

     You have informed us that you are entering into a loan transaction (the
"Loan") with CGI evidenced by Master Loan Agreement (the "Master Loan
Agreement") dated as of January 24, 1997, which contemplates the execution of a
Security Agreement (the "Security Agreement") and an Assignment of Loan
Documents (the "Assignment"), copies of which are attached hereto as Exhibits C-
1 and C-2, pursuant to which CGI will grant to Farm Credit a security interest
in the Loan Documents. You have also informed us that the Loan Documents, copies
of which are attached hereto as Exhibits D and E, will grant to CGI security
interests in all of Colorado Greenhouse's right, title and interest in and to
all crops now or hereafter planted, growing or stored on the Premises (as
defined in the Greenhouse Lease, and any such crops, herein the "Crops"), all
material and supplies utilized in the planting, growing, harvesting and
packaging of such Crops, of the type described on Exhibit A attached hereto,
which are now (or may hereafter be) stored on the Premises (the "Supplies"), the
equipment described on Exhibit B attached hereto, which is or may be located on
the Premises (the "Equipment") and all the other property owned by Colorado
Greenhouse described therein as the Collateral (such property herein referred
to as the "CGI Collateral").

     We acknowledge for your benefit that Colorado Greenhouse has not granted
any liens or security interests to us or for our benefit, and we disclaim any
interest in any of the Crops, Supplies or Equipment.

     We also agree for the benefit of Farm Credit that we will not claim any
crops which are now or may hereafter be planted on the Premises prior to the
termination of Colorado Greenhouse's right to possession of the Premises and any
crops now or hereafter stored on the Premises by Colorado Greenhouse as being
part of the Facility encumbered by the Deed of Trust.

     As long as either Thermo or RMP is entitled to possession of the Facility,
the undersigned Lenders agree not to interfere with any rights Farm Credit has
under the Consent.

     Lenders agree that after they have or their authorized representative has
obtained possession of the Facility under the rights set forth in the Deed of
Trust or otherwise, Farm Credit may from time to time, through its authorized
representative, during normal business hours and with 24 hours written notice to
the Lenders at the address set forth herein, enter the Premises for the
purposes of caring for the Crops and removing the
<PAGE>
 
Colorado Springs Production Credit Association

Page 3

Crops, Supplies, Equipment and any other property that is owned by Colorado
Greenhouse (as determined by reasonable and customary evidence thereof) which
constitutes CGI Collateral.

     After the Lenders or their authorized representatives have obtained
possession of the Facility under the rights set forth in the Deed of Trust or
otherwise, the Lenders shall permit Farm Credit immediate access to the Facility
at any time if Farm Credit notifies the Lenders that such immediate access is
necessary to prevent the value of the Crops from being impaired given their
perishable nature and the controlled conditions under which they are grown,
harvested and stored.

     Farm Credits right to enter and remain upon the Premises and to remove
therefrom the CGI Collateral as hereinbefore set forth shall terminate on the
date which is the later of:

     (a)  the date 60 days after the Lenders have (i) taken possession of the
          Facility and (ii) provided Farm Credit written notice of such
          termination; or

     (b)  the earlier of (i) the date 30 days after the completion of the
          harvest of all Crops which were planted on the Premises prior to the
          date Colorado Greenhouse's right to possession of the Premises
          terminated or (ii) 10 months after the date Colorado Greenhouse's
          right to possession of the Premises terminated.

     Farm Credit agrees to promptly and at its own expense repair any damages
to the Facility caused by either it or its authorized representatives while on
the Facility. In furtherance of the foregoing, Farm Credit shall indemnify and
hold the Lenders and their respective affiliates, officers, directors and agents
harmless from any loss, liability or damage incurred or suffered by any such
persons or entity as a direct or proximate result of the acts or omissions of
Farm Credit or its authorized representatives while Farm Credit or its
authorized representatives are present at the Facility.

     The Lenders acknowledge and accept that Thermo and RMP have agreed that the
making of any distributions by Colorado Greenhouse to its members after the
payment of all of its other obligations then due (including, without limitation,
all payments due under the O&M Agreement), regardless of the purposes for which
such funds are used by the members of Colorado Greenhouse (including the
construction and operation of any new greenhouses), shall not cause Colorado
Greenhouse to be in violation of Section 3.3(a) of the O&M Agreement.

     We understand that it is the intention of CGI that certain of the proceeds
of the loans to be made by Farm Credit to CGI under the Master Loan Agreement
are to be utilized to pay the costs of constructing a new greenhouse facility
(the "New Greenhouse") at the premises of Thermo's cogeneration facility. We
further understand that in connection with the construction of the New
Greenhouse, Thermo may request that the Lenders consent to certain actions
proposed to be taken by Thermo (or its affiliates) including, without
limitation, the grant to CGI of certain easements, the sale of certain premises
to CGI, the sale of natural gas by Thermo to CGI, and the provision or sharing
of certain water and wastewater, disposal rights to or with CGI. Please be
advised that by executing and delivering this consent to you, the Lenders are
not in any way undertaking to you or to CGI or Colorado Greenhouse to consent to
or consider any such actions and that the Lenders are granting this consent
based upon the mutual understanding of the Lenders, Farm Credit, CGI or Colorado
Greenhouse that the Lenders have no obligations whatsoever to Farm Credit, CGI
or Colorado Greenhouse to consent to or consider any such actions by Thermo.

     This consent shall terminate and be of no further force and effect in the
event that Farm Credit shall agree to any amendment to or waive, or accept any
waiver of, (a) the provisions of Section 2(D) of the Pledge Agreement, dated as
of January 24, 1997 (the "Pledge Agreement"), made by CG Member, Inc., a
Delaware corporation ("CG Member") to Farm Credit, a copy of which is attached
hereto as Exhibit F, or any other provision of the Pledge Agreement if such
amendment or waiver affects the application or effect of the provisions of
Section 2(D) thereof or (b) the provisions of Section 2.2, 2.3 or 8.1 of the
Colorado Greenhouse LLC Loan Supplement, dated as of January 24, 1997 (the "LLC
Loan Supplement"), between Farm Credit and CGI, a copy of which is attached
hereto as Exhibit G, or any other provision of the LLC Loan Supplement if such
amendment or waiver affects the application or effect of the provisions of any
such Section. This consent shall also terminate upon the termination of the LLC
Loan Supplement. Finally, this consent is given based upon our understanding
that the shares of CG Member have not been and will not be pledged to Farm
Credit.

set forth in the MLA and this Supplement, Lender agrees to make Advances for
construction to CGI from time to time during the period set forth below in an

Commitment, amounts borrowed and later repaid may not be reborrowed.

     SECTION 2.2  PURPOSE.  The purpose of the Construction Commitment is to (i)
finance CGI's acquisition of real property and attendant water rights in New
Mexico and Colorado, as is more particularly described in Exhibit "G," hereof
(the "Property");  (ii) the construction of two new twenty-acre (20-acre)
greenhouse facilities thereon (the "Improvements") identified in the plans and
specifications provided to and approved by Lender pursuant to Section 7.1(b)
hereof (as the same may be amended pursuant to Section 10.1), (the "Plans");
(iii) the installation of necessary Fixtures and Equipment for the effective
operation of the greenhouse facilities; and (iv) to capitalize interest during
the construction and start-up phase in accordance with GAAP; and CGI agrees to
utilize the proceeds of the Construction Commitment for  these purposes only.

     SECTION 2.3  EXPIRATION OF CONSTRUCTION COMMITMENT.  Lender's obligations
to make Advances on the Construction Commitment shall expire on September 30,
1997, or such later date as Lender may in its sole discretion authorize in
writing.


                                   ARTICLE 3

                                PROMISSORY NOTE

     SECTION 3.1  PROMISSORY NOTE.  CGI promises to repay the Advances in
accordance with the Promissory Note in the form of note attached as Exhibit "C,"
which Exhibit is incorporated herein by this reference.  If any installment due
date is not a Business Day, then such installment shall be due and payable on
the next Business Day.  In addition to the above, CGI promises to pay interest
on the unpaid principal balance hereof at the times and in accordance with the
provisions set forth in Article 3.3 hereof.

     SECTION 3.2  PRINCIPAL REPAYMENT AND MATURITY.    The Promissory Note, this
Supplement and the balance of all Advances outstanding on the expiration of the
Construction Commitment shall be due and payable in equal monthly installments
of principal repayment, with the first such installment being due on the 1st day
of January, 1998.  The principal balance shall amortize in accordance with the
Schedule of Payments to be attached hereto as Exhibit "E" upon the expiration of
the Construction Commitment, and shall mature on December 31, 2006 ("Maturity").

     3.3  PAYMENT OF INTEREST.  Interest accruing during construction and start-
up shall be capitalized pursuant to Section 2.2 hereof, and thereafter the
interest accruing on the outstanding balance of the Advances at the rate
provided in Article  5 hereof shall be paid monthly in arrears, with 


                                       3
<PAGE>
 
the first such payment due on the 1st day of November, 1997, and on the 1st day
of each month thereafter until the entire amount shall have been paid in full.


                                   ARTICLE 4
                           DISBURSEMENT OF PROCEEDS

     SECTION 4.1  DISBURSEMENT PROCEDURES.

          (a)  FUNDING ORDER.  Disbursement of funds to pay acquisition and
construction costs on each greenhouse shall be for each greenhouse first from
funds placed by CGI in the Special Construction Account held by Lender until
CGI's equity committed to each greenhouse of FOUR MILLION FIVE HUNDRED THOUSAND
DOLLARS ($4,500,000) shall have been disbursed, then from Advances on the
Construction Commitment.

          (b)  LIMITS ON ADVANCES.  Lender shall not be required to Advance
funds (i) for any category or line item of acquisition or construction cost an
amount greater than the amount specified therefor in the Project budget; or (ii)
for any services not yet performed or for materials or goods not yet
incorporated into the Improvements or delivered to and properly stored on the
Property.  No Advance hereunder shall exceed ninety percent (90%) of the
aggregate costs actually paid or currently due and payable and represented by
invoices accompanying a Request for Construction Loan Advance submitted pursuant
to Section 7.2 (the remaining percentage of such costs is hereinafter referred
to as "Retainage"). Advances shall be in the minimum amount of $1,000,000, and
not more frequently than the 5th day and the 20th day of each month during the
term of the Construction Commitment.

          (c)  ADVANCE OF RETAINAGE.  The Retainage (and in no case greater than
the unused bal  ance of the Construction Commitment allocated for construction)
will be Advanced by Lender to CGI upon satisfaction of the following conditions:

               (i)    The proper and timely filing for recordation of a notice
of completion;
               (ii)   Expiration of the appropriate time periods allowed by law
for the filing of mechanics' liens and receipt of verification from CGI that no
liens have been filed prior to or dur ing such period or receipt from CGI of
lien waivers from all subcontractors and releases of any such liens which have
been filed; and
               (iii)  The issuance to Lender of an ALTA mortgagee's policy of
title insurance with appropriate endorsements reflecting the aggregate amount
advanced hereunder and insuring the property to be free and clear of any and all
materialmen's and mechanics' liens, all in form and con  tent satisfactory to
Lender.

     SECTION 4.2  PAYMENTS TO THIRD PARTIES.  At its option and without further
authorization from CGI, Lender is authorized to make Advances under the
Construction Commitment by paying, directly or jointly with CGI, any person to
whom Lender in good faith determines payment is due and any such Advance shall
be deemed made as of the date on which Lender makes such payment and shall be
secured under the Mortgage securing the Construction Commitment and any other
loan documents securing the Construction Commitment as fully as if made directly
to CGI.  Lender shall comply with the disbursers notice provisions of the Laws
of Colorado, C.R.S. (S) 38-22-126 and any equivalent provision of New Mexico
Law.

                                   ARTICLE 5

                                   INTEREST

     SECTION 5.1  PRIME RATE OPTION.  Except as CGI may elect from time to time
in accordance with Section 5.2 hereof, Advances shall bear and CGI agrees to pay
interest equal to the Prime Rate. Prime Rate shall mean for any day, the rate
defined as the "prime rate" as published from time to time in the Eastern
Edition of The Wall Street Journal as the average prime lending rate for
seventy-five percent (75%) of the United States' thirty (30) largest commercial
banks, or if The Wall Street Journal shall cease publishing the "prime rate" on
a regular basis, such other regularly published average prime rate application
to such commercial banks as is acceptable to CGI in its reasonable discretion.

     SECTION 5.2  U. S. TREASURY RATE OPTION.  At the request of CGI, the rate
of interest charged on the Advances may be fixed at a rate per annum equal to
two and one-half percent (2.5%) above the U. S. Treasury Rate.  For purposes
hereof, U. S. Treasury Rate shall mean the yield to maturity of U. S. Treasury
instruments having the same maturity date as the Advances, as indicated by
Telerate (page 5) at approximately 9:30 a.m. Eastern Time on the date the rate
is fixed.  If, however, no yield is available for the period selected, then the
rate shall be interpolated based on the rates quoted for the next longest and
shortest period of time.  In the event Telerate ceases to provide such
quotations or materially changes the form or substance of page 5 (as reasonably
determined by Lender), the Lender will notify CGI and the parties hereto will
agree upon a substitute basis for obtaining such quotations.  Notwithstanding
the foregoing, if the spread between Lender's costs of funds (as reasonably
determined by Lender according to its methodology) and the U.  S. Treasury Rate
should widen (or lessen) from the spread in effect for the same period of time
on the date hereof, then the spread over the U. S. Treasury Rate shall be
automatically adjusted upward (or downward) to reflect any such change.
However, the first such adjustment may not be made until January 1, 2000, and no
adjustment shall be applied retroactively to any Advances made prior to the date
of such adjustment.  Under this option, individual amounts may be fixed for
periods ranging from one (1) year to Maturity, and the minimum amount that may
be fixed at any one time for any single period shall be One Million Dollars
($1,000,000).  Rates may only be fixed for periods which expire on a Business
Day and may not be fixed in such a manner as to require CGI to have to prepay
any fixed rate balance in order to pay any installment of principal.  Upon the
expiration of any fixed rate period, interest shall automatically accrue at the
rate set forth in Section 5.1 above, unless the amount fixed is repaid or CGI
fixes the rate pursuant to this Section 5.2 for a new period.

     SECTION 5.3  FEES.  CGI agrees to pay fees:

          (a)  ORIGINATION FEE.  At the closing of this Supplement, CGI shall
pay a fee to the Lender equal to one and one-half percent (1.5%) of the total
Construction Commitment.  CGI shall be credited at closing for the ten percent
(10%) of the origination fee paid in advance on the 21st day of November, 1996,
in the amount of $22,500.

          (b)  COMMITMENT FEE.  At the end of each quarter in which there has
been any unused Construction Commitment, CGI shall pay to Lender an unused
commitment fee of twenty-five (25) basis points on such unused Construction
Commitment.



                                       5
<PAGE>
 
     SECTION 5.4  PREPAYMENT.  The loans may be prepaid in whole or in part as
provided in the MLA.  Unless otherwise agreed, all prepayments will be applied
to principal installments in the inverse order of their maturity.


                                   ARTICLE 6

                                   SECURITY

     SECTION 6.1  COLLATERAL.  In addition to the Collateral described in the
MLA, the Security Agreement, the Guarantee, the Holdings Pledge, and the CG
Member Pledge, Advances on the Construction Commitment shall be secured by the
assignment of the construction contracts, Plans, Approvals and the like, and the
Mortgages.


                                   ARTICLE 7

                        ADDITIONAL CONDITIONS PRECEDENT

     SECTION 7.1  INITIAL ADVANCE.  Lender's obligation to make the initial
Advance hereunder is subject to satisfaction of each of the following additional
conditions precedent on or before the date of such Advance:

          (a)  MINIMUM EQUITY.  CGI certifies that a minimum of Twelve Million
Dollars ($12,000,000) in new equity capital has been raised, and that a minimum
of Ten Million Dollars ($10,000,000) of the net proceeds of the equity offering
will be placed in a Special Construction Account with Lender for future
construction disbursements. Notwithstanding the foregoing, not more than Nine
Million Dollars ($9,000,000) will be used for construction disbursements.
Immediately after the Final Payment (as that term is defined in the construction
contracts) is made on both new greenhouses, and if no Event of Default has
occurred and is continuing, Lender shall release all sums remaining in the
Special Construction Account to CGI, however, after the Final Payment is made on
the first greenhouse completed, CGI may request release of funds (other than
funds needed for construction) based upon the percentage of completion of the
second greenhouse.  Upon such request Lender will, in good faith, consider and
grant so much of the request, which in Lender's reasonable discretion is
warranted.

          (b)  PROJECT BUDGET AND SCHEDULE, CONTRACTS AND PLANS.  That Lender
receive and approve for each of the New Mexico and Colorado greenhouses (i) a
budget setting forth the total estimated direct and indirect costs for the
construction of the Improvements, including line item cost breakdowns for all

funds to pay such costs (the "Project Budget"); (ii) a schedule setting forth,
by trade, job, and subcontractor, the estimated dates of commencement and
completion of construction of the Improvements (the "Project Schedule"); (iii) a
schedule of the amounts and times of Advances anticipated to be requisitioned by
CGI from time to time during the term of construction of the Improvements (the
"Disbursement Schedule"); (iv) a list of all subcontractors and materialmen who

all approvals, consents, permits and licenses required under such Laws (the
"Project Approvals") which have been obtained or are to be obtained by CGI
relating in any way to the acquisition, construction or the contemplated
operation of the Improvements (including, without limitation, those relating to
zoning, building, use and occupancy, fire prevention and health); and (vi) a

and liability insurance (including contractual liability) carried during the
course of construction, naming Lender as an additional insured, with liability
insurance limits for death of or injury to persons of not less than One Million
Dollars ($1,000,000) and for damages to property of not less than Five Million
Dollars ($5,000,000) or such other limits if any are established under the
construction contract(s).  Without limiting the provisions in the MLA or the
foregoing, CGI agrees to obtain Builder's Risk casualty insurance covering fire

liens on the Property, subject only to exceptions approved in writing by Lender
in its reasonable discretion.  In the event any construction of the Improvements
has commenced prior to issuance of such title policy, CGI will obtain any and
all indemnification agreements and/or lien waiver agreements required by the
title insurer for issuance of such title insurance policies.

          (b) CONSTRUCTION CERTIFICATE.  That Lender receive from the Project

the Improvements to the date thereof has been performed in a good and
workmanlike manner and in accordance with the Plans, stating the estimated total
cost of construction of the Improvements, stating the percentage of in-place
construction of the Improvements, and stating that the remaining non-disbursed
portion of the loan is adequate to complete the construction of the

                                   ARTICLE 8

                        REPRESENTATIONS AND WARRANTIES

     In addition to the representations and warranties contained in the MLA
subject only to those exceptions set forth in the Disclosure Schedule, CGI
represents and warrants as follows.

     SECTION 8.1    PROJECT APPROVALS; CONSENTS; COMPLIANCE.  CGI has obtained
all Project Approvals relating to the construction and operation of the
Improvements.  All such Project Approvals heretofore obtained remain in full
force and effect and CGI has no reason to believe that any such Project Approval
not heretofore obtained will be obtained by CGI in the ordinary course during or
following completion of the construction of the Improvements.  No such Project
Approval will terminate, or become void or voidable or terminable, upon any
sale, transfer or other disposition of the Property or the Improvements,
including any transfer pursuant to foreclosure sale under the Mortgage.  No
consent, permission, authorization, order, or license of any governmental
authority is necessary in connection with the execution, delivery, performance,
or enforcement of the Loan Documents to which CGI is a party, except such as
have been obtained and are in full force and effect. CGI is in compliance in all
material respects with all Project Approvals having application to the Property
or the Improvements,.  Without limiting the foregoing, there are no unpaid or
outstanding 



                                       8
<PAGE>
 
real estate or other taxes or assessments on or against the Property or the
Improvements or any part thereof (except only real estate taxes not yet due and
payable). CGI has received no notice nor has any knowledge or any pending or
contemplated assessment against the Property or the Improvements.

     SECTION 8.2  ENVIRONMENTAL COMPLIANCE.  Without limiting the provisions of
the MLA, all property owned or leased by CGI, including, without limitation, the
Property and the Improvements, and all operations conducted by it are in
compliance in all material respects with all Laws and all Project Approvals
relating to environmental protection, the failure to comply with which could
have a material adverse effect on the condition, financial or otherwise,
operations, properties, or business of CGI, or on the ability of CGI to perform
its obligations under the Loan Documents.

     SECTION 8.3  FEASIBILITY.  Each of the Project Budget, the Project Schedule
and the Disbursement Schedule is realistic and feasible.


                                   ARTICLE 9

                             AFFIRMATIVE COVENANTS
                                        
     In addition to the affirmative covenants contained in the MLA, CGI agrees
to:

     SECTION 9.1  REPORTS AND NOTICES.

          (a)  REGULATORY AND OTHER NOTICES.  Promptly after receipt thereof,
furnish to Lender copies of any notices or other communications received from
any governmental authority with respect to the Property, the Improvements, or
any matter or proceeding the effect of which could have a material adverse
effect on the condition, financial or otherwise, operations, properties, or
business of CGI, or the ability of CGI to perform its obligations under the Loan
Documents.

          (b)  NOTICE OF NONPAYMENT.  Promptly after the filing or receipt
thereof, furnish to Lender a description of or a copy of any lien filed by or
any notice, whether oral or written, from any laborer, contractor, subcontractor
or materialman to the effect that such laborer, contractor, subcontractor or
materialman has not been paid when due for any labor or materials furnished in
connection with the construction of the Improvements.

          (c)  NOTICE OF SUSPENSION OF WORK.  Furnish to Lender prompt notice of
any suspension in the construction of the Improvements, regardless of the cause
thereof, in excess of five (5) days and a description of the cause for such
suspension.

     SECTION 9.2  CONSTRUCTION LIENS.  Pay or cause to be removed, within five
(5) days after notice from Lender, any Lien on the Improvements or Property,
provided, however, that CGI shall have the right to contest in good faith and
with reasonable diligence the validity of any such lien or claim upon furnishing
to the appropriate title insurance company such security or indemnity as it may
require to induce said title insurance company to issue its title insurance
commitment or its mortgage title insurance policy insuring against all such
claims or Liens, and provided further that Lender will not be required to  make
any further Advances of the proceeds of the Construction Commitment until 



                                       9

binder have been so insured against by the title insurance company.

     SECTION 9.3  IDENTITY OF CONTRACTORS; ETC.  Furnish to Lender from time to
time on the request of Lender, in a form acceptable to Lender, correct lists of
all contractors, subcontractors and suppliers of labor and material supplied in
connection with the construction of the Improvements and true and correct copies
of all executed contracts, subcontracts, and supply contracts. Lender may
contact any contractor, subcontractor, or supplier to verify any facts disclosed
in the lists and contracts. All contracts and subcontracts relating to
construction of the Improvements must contain provisions authoriz ing such
contractor, subcontractor or supplier to provide to Lender the listed
information and copies of contracts, and to disclose to Lender any information
regarding the performance of the contract.

     SECTION 9.4  LIEN WAIVERS.  Furnish to Lender, at any time and from time to
time upon the request of Lender, lien waivers bearing a then current date and
prepared on a form satisfactory to Lender from such contractor, subcontractor,

                              NEGATIVE COVENANTS

     In addition to the negative covenants contained in the MLA, CGI will not:

     SECTION 10.1  CHANGE ORDERS.  Allow any substantial deviation, addition,
extra, or change order to the Plans, Project Budget or Project Schedule and will
not make any material change in any contract or subcontract (including, but not
limited to, those with any contractor, subcontractor, architect or engineer)
without Lender's prior written approval.  All requests for substantial changes
shall be made using a Change Order Request in the form of Exhibit "A" attached
hereto.  For the purposes hereof, the term "substantial" shall mean an addition
or extra which exceeds One Hundred Thousand Dollars ($100,000) in the aggregate
for each greenhouse, or for any particular item if such change would increase
the cost for such item by five percent (5%) or greater.  Lender will have a
reasonable time to evaluate any requests for its approval of any changes
referred to in this covenant, and will not be required to consider approving any
changes unless all other approvals that may be required have been obtained.
Lender may approve or disapprove changes in its sole discretion.  All contracts
and subcontracts relating to the construction of the Improvements must contain
provisions satisfactory to Lender implementing the above provisions of this
covenant.  CGI shall promptly provide to Lender copies of all change orders
that, pursuant to the above described procedures, did not require Lender's prior
written approval.

     SECTION 10.2  MATERIALS.  Purchase or install any materials, equipment,
fixtures, or articles of personal property for the Improvements if such shall be
covered under any security agreement or other agreement where the seller
reserves or purports to reserve title or the right of removal or repossession,
or the right to consider them personal property after their incorporation into
the Improvements.

                                  ARTICLE 11

                                  CASUALTIES

     SECTION 11.1  RIGHT TO ELECT TO APPLY PROCEEDS.  In case of material loss
or damage to the Property or the Improvements by fire or other casualty, by a
taking by condemnation for public use or the action of any governmental
authority or agency, or the transfer by private sale in lieu thereof, either
temporarily or permanently, or otherwise, if in the sole judgment of Lender
there is reasonable doubt as to CGI's ability to complete construction of the
Improvements on or before the Completion Date by reason of such loss or damage
or because of delays in making settlements with governmental agencies or
authorities or with insurers, Lender may terminate its obligations to make
Advances hereunder and elect to collect, retain and apply to the outstanding
balance all proceeds of the taking or insurance after deduction of all expenses
of collection and settlement, including attorneys' and adjusters' fees and
charges.  In the event such proceeds are insufficient to pay the outstanding
balance in full, Lender may declare the balance remaining unpaid on the
outstanding balance to be due and payable forthwith and avail itself of any of
the remedies afforded hereby as in case of any Event of Default.

     SECTION 11.2  ELECTION NOT TO APPLY PROCEEDS.  In case Lender does not
elect to apply such proceeds to the outstanding balance, CGI will:

          (a)  SETTLE.  Proceed with diligence to make settlement with the
governmental agencies or authorities or the insurers, as the case may be, and
cause the proceeds to be paid to CGI.

          (b)  RESUME CONSTRUCTION.  Promptly proceed with the resumption of
construction of the Improvements, including the repair of all damage and
restoration to its former condition.

     SECTION 11.3  USE OF PROCEEDS.  All such proceeds shall be fully used
before the disbursement of any further proceeds of the Construction Commitment.


                                  ARTICLE 12

                            OTHER RIGHTS OF LENDER

     SECTION 12.1  RIGHT TO INSPECT.  Lender or its agent may enter on the
Property at any time and inspect the Improvements.  If the construction of the
Improvements is not satisfactory to Lender, Lender may stop the construction and
order its replacement or the correction thereof or additions thereto, whether or
not said unsatisfactory construction has been incorporated in the Improvements,
and withhold all Advances hereunder until such construction is satisfactory to
Lender.  Such construction shall promptly be made satisfactory to Lender.

     SECTION 12.2  NO OBLIGATION OF LENDER.  Neither Lender nor any inspector
hired pursuant to Section 12.3 below is obligated to construct or supervise
construction of the Improvements.  Inspection by Lender or such inspector
thereof is for the sole purpose of protecting Lender's security and is not to be
construed as a representation that there will be compliance on anyone's part
with the Plans or that the construction will be free from faulty material or
workmanship.  Neither Lender nor such in-  



                                      11
<PAGE>
 
spector shall be liable to CGI or any other person concerning the quality of
construction of the Improvements or the absence therefrom of defects. CGI will
make or cause to be made such other independent inspections as it may desire for
its own protection.

     SECTION 12.3  RIGHT TO EMPLOY INDEPENDENT ARCHITECT OR ENGINEER.  Lender
reserves the right to employ an independent construction architect or engineer,
among other things, to review the Project Budget, the Project Schedule and the
Plans, inspect all construction of the Improvements and the periodic progress of
the same, and review all Requests for Construction Loan Advances and change
orders, the cost therefor to be the sole responsibility of CGI and shall be paid
by CGI upon demand by Lender.

     SECTION 12.4  INDEMNIFICATION AND HOLD HARMLESS.  CGI shall indemnify and
hold Lender harmless from and against all liability, cost or damage arising out
of this Supplement or any other Loan Document or the transactions contemplated
hereby and thereby, including, without limitation, (i) any alleged or actual
violation of any Law or Project Approval relating to the Property or the
Improvements and (ii) any condition of the Property or the Improvements whether
relating to the quality of construction or otherwise and whether Lender elects
to complete construction upon an Event of Default or discontinues or suspends
construction pursuant to this Section, except for any liability, cost or damage
arising from Lender's own gross negligence or willful misconduct. Lender may
commence, appear in or defend any such action or proceeding or any other action
or proceeding purporting to affect the rights, duties or liabilities of the
parties hereunder, or the Improvements, or the Property, or Advances of the
Construction Commitment, and CGI agrees to pay all of Lender's costs and
expenses, including its reasonable attorneys' fees, in any such actions. The
obligations of CGI under this Subsection shall survive the termination of this
Agreement.


                                  ARTICLE 13

                               EVENTS OF DEFAULT

     In addition to the events of default set forth in the MLA, each of the
following shall constitute an "Event of Default" hereunder:

construction of the Improvements for more than fifteen (15) consecutive days,
except for strikes, acts of God, or other causes beyond CGI's control, or any
cessation at any time in construction of the Improvements for more than thirty
(30) consecutive days, regardless of the cause.

     SECTION 13.2  INSUFFICIENCY OF LOAN PROCEEDS.  Lender, in its sole
discretion, shall determine that the remaining undisbursed portion of the
Construction Commitment is or will be insufficient to fully complete the
Improvements in accordance with the Plans.

                                  ARTICLE 14

                             REMEDIES UPON DEFAULT

     In addition to the remedies set forth in the MLA, upon the occurrence of
and during the contin  uance of each and every Event of Default:

     SECTION 14.1  COMPLETION.  Lender may (but shall not be obligated to) take
over and complete construction of the Improvements in accordance with the Plans
approved by Lender with such changes as Lender may, in its sole discretion, deem
appropriate, all at the risk, cost, and expense of CGI. Lender may assume or
reject any contracts entered into by CGI in connection with the Improvements,
and may enter into additional or different contracts for services, labor, and
materials required, in the sole judgment of Lender, to complete the construction
of the improvements.  All sums, including reasonable attorneys' fees, charges or
fees for supervision and inspection of the construction, and for any other
necessary purpose in the discretion of Lender, expended by Lender in completing
the construction of the Improvements (whether aggregating more or less than the
amount of this Construction Commitment) shall be deemed Advances made by Lender
to CGI under this Construction Commitments, and CGI shall be liable to Lender
for the repayment of such sums, together with interest on such amounts from the
date of their expenditure at the Default Interest Rate specified above.  Lender
may, in its sole discretion, at any time, abandon work on the construction of
the Improvements after having commenced such work, and may recommence such work
at any time, it being understood that nothing in this Section shall impose any
obligation on Lender to complete or not to complete the construction of the
Improvements.  In the event Lender elects to complete the construction, it may
demand such additional sums from CGI as may be necessary to complete
construction, which sums CGI shall promptly pay to Lender.  For the purposes of
carrying out the provisions of this section upon an Event of Default and for so
long as an Event of Default continues, CGI irrevocably appoints Lender its
attorney-in-fact, with full power of substitution to execute and deliver all
such documents, pay and receive such funds, and take such action as may be
necessary, in the judgment of Lender, to complete the construction of the
Improvements.  This appointment of attorney-in-fact is coupled with an interest
and given as security and is irrevocable.


                                  ARTICLE 15

                                 MISCELLANEOUS

     SECTION 15.1 NOTICE OF COMPLETION.  CGI appoints Lender as CGI's attorney-
in-fact to file of record any notice of completion, cessation of labor or any
other notice that Lender deems necessary to file to protect any of the interests
of Lender.  Lender, however, shall have no duty to make such filing.  This
appointment is coupled with an interest and given as security, and is
irrevocable.

     SECTION 15.2 SIGNS AND PUBLICITY.  CGI will allow Lender to post signs on
the Property at the construction sites for the purpose of identifying Lender as
the construction lender, and will use its best efforts to identify Lender as the
construction lender in publicity concerning the Project.



                                      13
<PAGE>
 
     SECTION 15.3 COOPERATION.  CGI will cooperate at all times with Lender in
bringing about the timely completion of the Improvements, and CGI will resolve
all disputes arising during the work construction in a manner which will allow
work to proceed expeditiously.

     SECTION 15.4 TERMINATION.  This Supplement shall terminate when the
indebtedness evidenced by the Promissory Note is paid in full and all
obligations, covenants, conditions, and agreements of CGI contained herein and
in the Loan Documents are performed and discharged, and, in such event, upon the
request of CGI and at the cost of CGI, Lender shall execute and deliver to CGI
instruments effective to evidence the termination of the Supplement.

     IN WITNESS WHEREOF, CGI has caused this Agreement to be executed, attested,
and sealed and Lender has caused this Agreement to be executed by their duly
authorized officers as of the date shown above.

                                PROMISSORY NOTE

FIFTEEN MILLION DOLLARS                                         January 24, 1997
$15,000,000.00                                                  Loan No. 2406649


     FOR VALUE RECEIVED, the undersigned, Colorado Greenhouse, Inc., a Delaware
corporation doing business in Colorado ("Maker"), hereby promises to pay to the
order of Colorado Springs Production Credit Association ("Lender"), a federally
chartered association of the Farm Credit System, ("Payee"), at its offices, at
Maturity as defined in the Construction Loan Supplement, in lawful money of the
United States of America, the principal amount of FIFTEEN MILLION DOLLARS
($15,000,000.00) or so much thereof as may have been Advanced and is outstanding
hereunder, together with interest on the outstanding principal balance from day
to day remaining, at the rates provided in the Construction Loan Supplement.
Interest accruing during construction and start-up shall be capitalized pursuant
to the Construction Loan Supplement, and thereafter the interest accruing hereon
shall be due and payable monthly in arrears, with the first such payment due on
the 1st day of November, 1997, and on the 1st day of each month thereafter, and
at Maturity. All unpaid principal balances of the Advances on this Promissory
Note shall be due and payable in equal monthly installments of principal
repayment, with the first such installment being due on the 1st day of January,
1998, and monthly thereafter in accordance with the Schedule of Payments
attached hereto and to the Construction Loan Supplement as Exhibit E, with the
final payment on December 31, 2006 ("Maturity"). All past due principal shall
bear interest at the Default Rate.

     This Promissory Note has been given to Payee pursuant to the Master Loan
Agreement dated as of the 24th day of January, 1997, and the Construction Loan
Supplement dated as of the 24th day of January, 1997, and all capitalized terms
used herein and not otherwise defined shall have the meaning provided therein.
Advances borrowed hereon and repaid may not be reborrowed.

     Upon the occurrence of any Event of Default, the holder hereof may, at its
option, declare the entire unpaid principal of and accrued interest on this
Promissory Note immediately due and payable without notice, demand or
presentment, all of which are hereby waived, and upon such declaration, the same
shall become and shall be immediately due and payable, and the holder hereof
shall have the right to foreclose or otherwise enforce all liens or security
interests securing payment hereof, or any part hereof, and offset against this
Promissory Note any sum or sums owed by the holder hereof to Maker.  Failure of
the holder hereof to exercise this option shall not constitute a waiver of the
right to exercise the same upon the occurrence of a subsequent Event of Default.

     If the holder hereof expends any effort in any attempt to enforce payment
of all or any part of any sum due the holder hereunder, or if this Promissory
Note is placed in the hands of an attorney for collection, or if it is collected
through any legal proceedings, Maker agrees to pay all costs, expenses and
reasonable fees incurred by the holder, including reasonable attorney's fees.

     This Promissory Note shall be governed by and construed in accordance with
the Laws of the State of Colorado and the applicable Laws of the United States
of America.
<PAGE>
 
     Maker and each surety, guarantor, endorser and other party ever liable for
payment of any sums of money payable on this Promissory Note jointly and
severally waive notice, presentment, demand for payment, protest, notice of
protest and non-payment or dishonor, notice of acceleration, notice of intent to
accelerate, notice of intent to demand, diligence in collecting, grace, and all
other formalities of any kind, and consent to all extensions without notice for
any period or periods of time and partial payments, before or after maturity,
and any impairment of any collateral securing this Promissory Note, all without
prejudice to the holder.  The holder shall similarly have the right to deal in
any way, at any time, with one or more of the foregoing parties without notice
to any other party, and to grant any such party any extensions of time for
payment of any of said indebtedness, or to release or substitute any such party
or part or all of the collateral securing this Promissory Note, or to grant any
other indulgences or forbearances whatsoever, without notice to any other party
and without in any way affecting the personal liability of any party hereunder.

     Maker hereby authorizes the holder hereof to record in its records all
Advances made to Maker hereunder and interest accruing thereon and all payments

                                     AS OF

                              JANUARY  24, 1997.


- --------------------------------------------------------------------------------
<PAGE>
 
                    SECURED CONTINUING GUARANTEE OF PAYMENT

     THIS GUARANTEE OF PAYMENT (this "Guarantee") is executed as of the 24th day
of January, 1997 by Colorado Greenhouse Holdings, Inc. (hereinafter referred to
as the "Guarantor") in favor of Colorado Springs Production Credit Association
(hereinafter referred to as "Lender").

                                  BACKGROUND

     Colorado Greenhouse, Inc. (the "Borrower") has obtained or may desire at
some point in time and/or from time to time to obtain loans, advances and other
financial accommodations from Lender. Owing to Borrower's financial condition
and/or other factors, Lender is not willing to extend or continue to extend
credit to the Borrower without the guarantee of the Guarantor.  The Borrower is
a wholly-owned subsidiary of the  Guarantor and the Guarantor has a financial
interest in the Borrower and is expecting to benefit from such credit, and
therefore the Guarantor is willing to furnish that guarantee in order to induce
Lender to extend or to continue to extend credit to the Borrower.

     NOW, THEREFORE, in order to induce Lender to extend credit to the Borrower
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Guarantor agrees as follows:

     SECTION 1  GUARANTEE.  The Guarantor hereby unconditionally and irrevocably
guarantees to Lender the punctual payment when due, whether at stated maturity,
by acceleration or otherwise, of all indebtedness, obligations and liabilities,
including without limitation all non-monetary covenants and other obligations,
of the Borrower to Lender, whether now existing or hereafter incurred, including
but not limited to those under or arising out of or in connection with any
loans, advances, acceptances, letters of credit, indemnities, foreign exchange
contracts or any other kind of contract or agreement under which the Borrower
may be indebted to Lender in any manner, whether for principal, interest, fees,
surcharges, expenses or otherwise. For ease of reference: (i) all such
indebtedness, obligations and liabilities shall hereinafter be collectively
referred to as the "Guaranteed Obligations"; and (ii) all instruments, documents
and agreements evidencing or relating to the Guaranteed Obligations (including
all loan agreements, promissory notes, reimbursement agreements, security
agreements, mortgages and deeds of trust) shall hereinafter collectively be
referred to as the "Loan Documents."

     SECTION 2  SECURITY AGREEMENT.  To secure the payment or performance of all
Guaranteed Obligations, the hereby grants to Lender a continuing security
interest in and to the following property and interests in property of the
Guarantor, whether now owned or existing or hereafter acquired or arising and
wheresoever located: all accounts, inventory, equipment, fixtures, farm
products, general intangibles, chattel paper, instruments, documents,
intellectual property, and all accessions to, substitutions for, and all
replacements, products and proceeds of the foregoing, all books and records
(including without limitation customer lists, credit files, computer programs,
printouts, data whether stored electronically or otherwise, and other computer
materials and records) pertaining to the foregoing, and all insurance policies
insuring the above collateral. Without limiting any of the foregoing, Guarantor
also (i) grants to Lender a continuing security interest in and to and a pledge
of all its interests in (as more specifically set forth in the "Pledge
Agreement" of even date herewith) the Guarantor's interests in Borrower, and
(ii) shall cause CG Member, Inc. ("CG Member"), a wholly-owned subsidiary of
Guarantor, also to grant to Lender a pledge and security interest in all its
interest in its subsidiary, Colorado Greenhouse, LLC (the "LLC"). All of the
property and interests of the Guarantor described

<PAGE>
 
in this Section 2 (including, without limitation, the Guarantor's interest in
the Borrower) and CG Member's interest in the LLC shall hereinafter be referred
to as the "Collateral."

     SECTION 3  GUARANTY OF PAYMENT; WAIVER OF DEFENSES, ETC.  This Guarantee is
a guarantee of payment and not of collection, and of performance of Borrower's
obligations to Lender. The Guarantor acknowledges and agrees that this Guarantee
is an absolute and independent obligation of the Guarantor and therefore waives
any right to require that any action be brought against the Borrower, another
guarantor or any other Person or entity which is liable for all or any part of
the Guaranteed Obligations, or to require that resort be had at any time to any
security for the Guaranteed Obligations or to any right of setoff or similar
right. The Guarantor's obligations hereunder shall be payable on demand and
shall be absolute and unconditional irrespective of (and the Guarantor hereby
expressly waives any defense or claim of discharge based on): (i) the alteration
or modification from time to time (whether material or otherwise); (ii) the
waiver by Lender of the Borrower's compliance with any of the terms and
conditions of the Loan Documents; (iii) the forbearance by Lender from
exercising any right or remedy it may have under the Loan Documents or under
law; (iv) any inability, failure, neglect or omission to obtain, perfect,
maintain, enforce, or realize upon any Collateral for the Guaranteed
Obligations, or to pursue or obtain any deficiency judgment against the Borrower
following any foreclosure of any security interest, mortgage or deed of trust;
(v) the loss or impairment of any Collateral, the subordination or release of
Lender's lien thereon, or the sale, pledge, surrender, exchange or substitution
of any Collateral; (vi) Lender releasing, waiving, discharging, or modifying the
obligations of one or more other guarantors (whether a party hereto or to a
separate agreement with Lender); (vii) the acceptance by Lender of any partial
payment on the Guaranteed Obligations or any Collateral therefor, or Lender
settling, subordinating, compromising, discharging, or releasing the Guaranteed
Obligations or any Collateral therefor; (viii) the unenforceability of the loan
Documents; (ix) any defenses or counterclaims assertable by the Borrower,
including any defense or counterclaim based on failure of consideration, fraud,
statute of frauds, bankruptcy, statute of limitations, lender liability, and
accord and satisfaction; (x) any setoff, counterclaim, recoupment or similar
right assertable by the Borrower, the Guarantor, or other guarantor (whether a
party hereto or to a separate guarantee); or (xi) any other circumstance which
constitutes a legal or equitable discharge of a guarantor or surety. This
Guarantee shall continue in full force and effect until five business days after
written notice of termination shall have been received by Lender.
Notwithstanding the foregoing, such notice of termination shall not be effective
as to any Guaranteed Obligations: (1) existing prior to the effective date of
termination; (2) arising thereafter pursuant to any commitment to extend credit
entered into prior to the effective date of such notice (regardless of whether
Lender has or from time to time acquires a right to suspend or terminate such
commitment owing to the occurrence of a default or otherwise); (3) any
extensions, renewals, or refinancing(s) of any Guaranteed Obligations referred
to in (1) or (2) above made before or after the effective date of termination;
and (4) interest, fees, expenses and other Guaranteed Obligations relating to
any of the foregoing. In addition, no such notice of termination shall in any
manner impair or alter Lender's rights or obligations hereunder with respect to
such Guaranteed Obligations (including under Sections 3 and 6 hereof) or affect
or impair the obligations of any other guarantor (whether a party hereto or to a
separate guarantee).

     SECTION 4  SUBORDINATION AND SUBROGATION.  The Guarantor hereby agrees that
all indebtedness and other obligations of the Borrower (now existing or
hereafter incurred) to the Guarantor are and shall be subordinated in right of
payment to the prior payment in full by the Borrower of its obligations to
Lender under the Loan Documents.  During the existence of a default under the
Loan Documents, no payments by the Borrower shall be accepted by the Guarantor
with respect to such sub-

                                       2
<PAGE>
 
ordinated obligations and, if any such payments are inadvertently received, the
same shall be held in trust and promptly turned over to Lender. The Guarantor
hereby waives all claims, rights or remedies that it may have at law or in
equity (including, without limitation, any law subrogating the Guarantor to the
rights of Lender) to seek contribution, indemnification, or any other form of
reimbursement from the Borrower, any other guarantor, or any other person or
entity now or hereafter primarily or secondarily liable for any obligations of
the Guarantor to Lender for any disbursement made by the Guarantor under or in
connection with this Guarantee. The Guarantor hereby stipulates and agrees that
any such disbursement made by the Guarantor shall be a contribution to the
equity capital of the Borrower.

     SECTION 5  RECOVERY OF PAYMENT.  If any payment received by Lender and
applied to the Guaranteed Obligations is subsequently set aside, recovered,
rescinded, or required to be returned for any reason (including, without
limitation, the bankruptcy, insolvency or reorganization of the Guarantor), the
Guaranteed Obligations to which such payment was applied shall for the purposes
of this Guarantee and all instruments or documents executed in connection
herewith or securing the Guarantor's obligations hereunder, be deemed to have
continued in existence, and this Guarantee shall be enforceable as to such
Guaranteed Obligations as fully as if such applications had never been made.

     SECTION 6  INFORMATION REGARDING BORROWER; WAIVER OF NOTICES, ETC.  The
Guarantor assumes responsibility for keeping fully informed of the financial
condition of the Borrower, its liability hereunder and all other circumstances
affecting the Borrower's ability to pay and perform the Guaranteed
Obligations.  The Guarantor agrees that Lender shall have no duty to report to
or notify the Guarantor of: (i) any information which Lender shall receive about
the financial condition of the Borrower (including adverse matters); (ii)  the
Borrower's performance under the Loan Documents (including nonpayment or the
occurrence of any other default); (iii)  any circumstances bearing on the 
Borrower's ability to perform the Guaranteed Obligations; (iv)  any increases in
the amount of the Guaranteed Obligations or any renewals, extension or
refinancing(s) of any Guaranteed Obligation; (v)  any actions taken by Lender or
the Borrower under any Loan Document; (vi) any matters relating to another
guarantor; (vii)  any matter set forth in Section 3 hereof; or (viii) any other
matter relating to the Guaranteed Obligations; and the Guarantor hereby
expressly and unconditionally waives any defense or claim of discharge based on
the failure of Lender to report to notify the Guarantor of any such information.
In addition, the Guarantor hereby acknowledges that it has entered into this
Guarantee based upon its own independent knowledge of or investigation in to
the affairs of the Borrower and any other guarantor (whether a party hereto or
to a separate guarantee) and has not relied in any respect on Lender or any
officers, employees, or agents thereof.

     SECTION 7  REPRESENTATIONS AND WARRANTIES.  The Guarantor hereby represents
and warrants as follows:

          (A)  ORGANIZATION; POWER; ETC.  The Guarantor: (i) is duly organized,
validly existing, and in good standing under the laws of its state of
incorporation or formation; (ii) is duly qualified to do business and is in good
standing in each jurisdiction in which the transaction of its business makes
such qualification necessary; (iii)  has all requisite corporate and legal power
to own and operate its assets and to carry on its business and to enter into and

maintained all licenses, certificates, permits, authorizations, approvals, and
the like which are material to the conduct of its business or which my be
otherwise required by law, rule, regulation, ordinance, code, order or the like
(collectively, "Laws").

<PAGE>
 
          (B)  DUE AUTHORIZATION; NO VIOLATION; ETC.  The execution and delivery
by the Guarantor of, and the performance by the Guarantor of its obligations
under, this Guarantee and all instruments and documents executed in connection
herewith have been duly authorized by all requisite corporate or other action
on the part of the Guarantor and do not and will not: (i) conflict with, or
constitute (with or without the giving of notice and/or the passage of time
and/or the occurrence of any other condition) a default under, any other
agreement to which the Guarantor is a party or by which it or any of its
property may be bound or affected, or with any provision of its certificate of
incorporation, bylaws or other organizational documents; (ii) require the
consent, permission, authorization, order or license of any governmental

          (C)  BINDING AGREEMENT.  This Guarantee and each instrument and
document executed in connection herewith is, or when executed and delivered will
be, the legal, valid, and binding obligation of the Guarantor, enforceable in
accordance with its terms, subject only to limitations on enforceability
imposed by applicable bankruptcy, insolvency, reorganization, moratorium, or
similar Laws affecting creditor's rights generally.

          (D)  LITIGATION.  There are no pending legal, arbitration, or
governmental actions or proceedings to which the Guarantor is a party or to
which any of its property is subject which, if adversely determined, could
have a material adverse effect on the condition, financial or otherwise, 
operations, properties, or business of the Guarantor, or on the ability of the
Guarantor to perform its obligations hereunder or under any instrument or
document executed in connection herewith, and to the best of the Guarantor's
knowledge, no such actions or proceedings are threatened or contemplated.

          (E)  TITLE TO PROPERTY.  The Guarantor has title to, or valid
leasehold interests in, all of its property, real and personal, (other than any

property is subject to any "Lien" (as defined in Section 9(B) hereof), except as
permitted under Section 9(B).

          (F)  COMPLIANCE WITH LAWS, ENVIRONMENTAL MATTERS, ETC.  All of the

storage, processing or handling of hazardous waste or materials (as defined
under any environment Law) and no investigation, claim, litigation, proceeding,
order, judgment, decree, settlement, lien or the like with respect to any
environmental matter is proposed, threatened, anticipated or in existence with
respect to its properties or operations.  In addition, no environmental
contamination or condition currently exists on any property of the Guarantor or,
to its knowledge, any adjoining property, which could delay the sale or other
disposition of, or could have (or already has had) an adverse effect on the
value of, its property.

is operating its business in compliance with all of the covenants set forth in
this Guarantee.

     SECTION 8  AFFIRMATIVE COVENANTS.  Unless otherwise agreed to in writing by
Lender, while this Guarantee is in effect, whether or not any Guaranteed
Obligations are outstanding hereunder, the Guarantor agrees to:

          (A)  CORPORATE EXISTENCE, LICENSES, ETC.  Preserve and keep in full
force and effect its and its subsidiaries' existence and good standing in the
jurisdiction of their respective incorporation or formation, qualify and remain
qualified to transact business in all jurisdictions where such qualification

authorizations, approvals, and the like which are material to the conduct of its
business or required by Law.

applicable Laws, including, without limitation, all Laws relating to

same or similar business and similarly situated, and make such increases in
the type or amount of coverage as Lender may reasonably request.  All such
policies insuring any collateral for the Guarantor's obligations to Lender
shall have mortgagee or lender loss payable clauses or endorsements in form
and content acceptable to Lender in its reasonable discretion. At Lender's
request, certificates of insurance for all policies (or such other proof of
compliance with this Subsection as may be satisfactory to Lender) shall be
delivered to Lender.

          (D)  PROPERTY MAINTENANCE.  Maintain all of its property that is

                               PLEDGE AGREEMENT

     THIS PLEDGE AGREEMENT (this "Agreement"), dated as of the 24th day of
January, 1997, is made by Colorado Greenhouse Holdings, Inc. ("Grantor") in
favor of Colorado Springs Production Credit Association ("Secured Party").

                                  BACKGROUND

     From time to time, Secured Party may make loans and extend other types of
credit to or for the account of Colorado Greenhouse, Inc. ("CGI"), a wholly-
owned subsidiary of Grantor.  In order to induce Secured Party to do so, the
Grantor has furnished to Secured Party or is, simultaneously herewith,
furnishing to Secured Party, a continuing guarantee of payment (such guarantee,
as amended, supplemented or restated from time to time shall hereinafter be
referred to as the "Guarantee").  In order to secure the Grantor's obligations
under the Guarantee, the Grantor is entering into this Agreement.

                                   AGREEMENT

     NOW, THEREFORE, in order to induce Secured Party to extend credit to the
Borrower, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledge, Grantor hereby represents,
warrants, covenants, agrees and pledges as follows:

     SECTION 1  DEFINITIONS.  In addition to the terms defined elsewhere in this
Agreement, the following terms shall have the following meanings:

     CERTIFICATES shall mean all certificates, instruments or other documents
     now or hereafter representing or evidencing any Pledged Securities.

     GUARANTEE shall mean the Secured Continuing Guarantee granted by Guarantor
     to Secured Party of even date herewith.

     LOAN DOCUMENTS shall have the meaning given to that term in the Guarantee.

     OBLIGATIONS shall mean (1) the payment and performance of all obligations
     of the Grantor under the Guarantee and this Agreement, whether now existing
     or hereafter arising; and (2) the payment of all other indebtedness and the
     performance of all other obligations of the Grantor to Secured Party of
     every type and description, whether now existing or hereafter arising,
     fixed or contingent, as primary obligor or as guarantor or surety, acquired
     directly or by assignment or otherwise, or liquidated or unliquidated.

     PLEDGED COLLATERAL shall mean the Pledged Securities, the Certificates
     representing or evidencing the same, all right, title, interest,
     privileges, benefits, and preferences appertaining or incidental to such
     Pledged Securities, and any and all proceeds and products of the Pledged
     Securities (including, without limitation, all dividends, distributions,
     collections, redemption payments, liquidation payments, cash, and
     instruments).

<PAGE>

     PLEDGED SECURITIES shall mean:  (1) any and all shares of capital stock of
     CGI now owned or hereafter acquired by the Grantor; (2) any and all
     warrants, options or other rights to subscribe to or acquire any additional
     capital stock or member interests in such entity or entities; and (3) any
     and all securities, certificates, agreements, instruments or other
     documents now or hereafter issued in substitution, exchange or replacement
     of any of the foregoing or with respect thereto.

     SECTION 2  CREATION OF SECURITY INTEREST.

          (A)  PLEDGE OF PLEDGED COLLATERAL. As security for the Obligations,
Grantor hereby pledges and grants to Secured Party a continuing security
interest in and to all of its capital stock in CGI.  Grantor shall cause to be
noted in the records of CGI, which records the holders of capital stock of CGI,
the existence of this Agreement and Secured Party's security interest in the CGI
stock.

          (B)  DELIVERY OF CERTAIN PLEDGED COLLATERAL. Simultaneously with the
execution here  of, Grantor shall cause to be pledged and delivered to Secured
Party all Certificates evidencing the capital stock of the Borrower.  All such
Certificates (as well as any Certificates delivered to Secured Party pursuant to
the terms of this Agreement after the date hereof) shall be in suitable form for
transfer by delivery, or shall be accompanied by duly executed instruments of
transfer or assignment in blank, all in form and substance satisfactory to
Secured Party in its reasonable discretion.  Secured Party shall hold all
Certificates pursuant to this Agreement unless and until released in accordance
with Section 11 of this Agreement.

          (C)  NO MERGER. In the event that Secured Party acquires the ownership
of the Pledged Collateral by exercise of the rights granted herein or otherwise,
such ownership interest shall not merge with the Secured Obligations, and
security interests granted in the Loan Documents shall remain in full force,
effectiveness and enforceability at the option of the Secured Party.

order to:  (a) perfect and protect any pledge or security interest granted
hereby; (b) enable Secured Party to exercise and enforce Secured Party's rights
and remedies hereunder; and (c) preserve, protect, and maintain the Pledged
Collateral and the value thereof, including, without limitation, paying all
taxes, assessments, and other charges imposed on or relating to the Pledged
Collateral.

     SECTION 4  GRANTOR'S VOTING RIGHTS; DIVIDENDS; ETC. So long as no "Event
of Default" (as such term is defined in any Loan Document) occurs and remains
continuing:

          (A)  VOTING RIGHTS. Grantor shall be entitled to exercise any and all
voting and other consensual rights pertaining to the Pledged Securities, or any
part thereof, for any purpose not inconsistent with the terms of this Agreement,
the Guarantee or the Loan Documents.

          (B)  DIVIDEND AND DISTRIBUTION RIGHTS. Grantor shall be entitled to
receive and to retain and use any and all dividends or distributions and all
cash or other property paid, payable or otherwise paid or distributed in respect

                           -----------------                                    
distributions received in the form of capital stock, partnership units, and the
like

                                       2

<PAGE>

shall be delivered to the Secured Party to hold as Pledged Collateral and shall,
if received by Grantor, be received in trust for the benefit of Secured Party,
be segregated from the other property of the Grantor, and be forthwith delivered
to the Secured Party as Pledged Collateral in the same form as so received (with
any necessary endorsements).

     SECTION 5  GRANTOR'S RIGHTS DURING EVENT OF DEFAULT.  When an Event of
Default has occurred and is continuing:

          (A)  VOTING, DIVIDEND, AND DISTRIBUTION RIGHTS.  At the option of
Secured Party, all rights of Grantor to exercise the voting and other consensual
rights which would otherwise be entitled to exercise pursuant to Section 4(A)
above and to receive the dividends and distributions which it would otherwise be
authorized to receive and retain pursuant to Section 4(B) above, shall cease,
and all such rights shall thereupon become vested in Secured Party who shall
thereupon have the sole right to exercise such voting and other consensual
rights and to receive and to hold as Pledged Collateral such dividends and
distributions.  Secured Party shall, after deciding to exercise voting rights
with respect to the Pledged Collateral, give notice thereof to Grantor;
PROVIDED, HOWEVER, that: (1) neither the giving of such notice nor the receipt
- ------------------                                                            
thereof by Grantor shall be a condition to exercise of any rights of Secured
Party hereunder; and (2) Secured Party shall incur no liability for failing to
give such notice.

          (B)  DIVIDENDS AND DISTRIBUTIONS HELD IN TRUST.  All dividends and
other distributions which are received by Grantor contrary to the provisions of
this Agreement shall be received in trust for the benefit of Secured Party,
shall be segregated from other funds of Grantor, and shall be paid over to
Secured Party as Pledged Collateral in the same form as so received (with any
necessary endorsements).

     SECTION 6  IRREVOCABLE PROXY.  Grantor hereby revokes all previous proxies
with regard to the Pledged Securities and appoints Secured Party as its
proxyholder to attend and vote at any and all meetings of the shareholders,
partners or other owners of the Companies held on or after the date of the
giving of this proxy and prior to the termination of this proxy, and to execute
any and all written consents of shareholders, partners or other owners of the
Companies executed on or after the date of the giving of this proxy and prior to
the termination of this proxy, with the same effect as if Grantor had personally
attended the meetings or had personally voted the Pledged Securities or had
personally signed the written consents; PROVIDED, HOWEVER, that the proxyholder
                                        -----------------                      
shall have rights hereunder only upon the occurrence and during the continuance
of an Event of Default and only in the event the Secured Party, as proxyholder,
has decided to exercise voting rights with respect to the Pledged Securities or
any of them.  Grantor hereby authorizes Secured Party to substitute another
person as the proxyholder and, upon the occurrence or during the continuance of
any Event of Default, hereby authorizes and directs the proxyholder to file this
proxy and the substitution instrument with the secretary (or other authorized
official) of the Companies.  This proxy is coupled with an interest and is
irrevocable until such time as this Agreement is released in accordance with
Section 11 hereof.

     SECTION 7  TRANSFERS AND OTHER LIENS.  Grantor agrees that it will not:
(A) sell, assign, exchange, transfer or otherwise dispose of, or contract to
sell, assign, exchange, transfer or otherwise dispose of, or grant any option
with respect to, any of the Pledged Collateral; (B) create or permit to exist
any lien or right of others upon or with respect to any of the Pledged
Collateral; or (C) take any

                                       3
 
<PAGE>

action with respect to the Pledged Collateral which is inconsistent with the
provisions or purposes of this Agreement or any Loan Document.

     SECTION 8   SECURED PARTY APPOINTED ATTORNEY-IN-FACT.  Grantor hereby
irrevocably appoints the Secured Party as Grantor's attorney-in-fact, with full
authority in the place and stead of Grantor, and in the name of Grantor, or
otherwise, from time to time, in Secured Party's sole and absolute discretion,
to do any of the following acts or things if Grantor fails to do so promptly
after demand by the Secured Party:  (A) to do all acts and things (including
without limitation, the execution, filing and/or recording of all financing
statements and other documents) necessary or advisable to perfect and continue
perfected the security interests created by this Agreement and to preserve,
maintain, and protect the Pledged Collateral, including, without limitation, the
authority to pay, purchase, contest, and compromise any lien or right of others
which, in the reasonable judgment of Secured Party, appears to be prior or
superior to Secured Party's security interests; (B) to do any and every act
which Grantor is obligated to do under this Agreement; and (C) to endorse and
transfer the Pledged Collateral upon foreclosure by the Secured Party; PROVIDED,
                                                                       ---------
HOWEVER, that Secured Party shall be under no obligation whatsoever to take any
- --------                                                                       
of the foregoing actions, and Secured Party shall have no liability or
responsibility for any act (other than Secured Party's own gross negligence or
willful misconduct) or omission taken with respect thereto.  Grantor hereby
agrees to repay immediately upon demand all reasonable costs and expenses
incurred or expended by Secured Party in exercising any right or taking any
action under this Agreement, together with interest at a rate per annum equal at
all times to the Prime Rate as defined in the Loan Documents.

     SECTION 9   REASONABLE CARE.  Secured Party shall be deemed to have
exercised reasonable care in the custody and preservation of the Pledged
Collateral in its possession if the Pledged Collateral is accorded treatment
substantially equal to that which Secured Party accords its own property.  
Notwithstanding the foregoing and whether or not an Event of Default has
occurred or is continuing, Secured Party shall be under no duty or obligation
to: (A) exercise any voting or other rights with respect to the Pledged
Collateral; (B) make or give notices of default, presentments, demands for 
performance, notices of nonperformance or dishonor, protests, notices of protest
or notices of any other nature whatsoever in connection with the Pledged
Collateral on behalf of Grantor or any other person having any interest therein;
(c) ascertain or take action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relative to any Pledged; or (D) take any
necessary steps to preserve rights against the Companies or any other person
with respect to any Pledged Collateral. In addition, Secured Party does not
assume and shall not be obligated to perform the obligations of Grantor, if any,
with respect to the Pledged Collateral.

name of Secured Party or its nominee or nominees; and

               (6) in accordance with applicable laws, to foreclose the liens
and security interests created under this Agreement or under any other agreement
relating to the Pledged Collateral by any available judicial procedure or
without judicial process, and to sell, assign or otherwise dispose of the
Pledged Collateral or any part thereof, either at public or private sale or at
any broker's board or securities exchange, in lots or in bulk, for cash, on
credit or for future delivery, or otherwise, with or without representations or
warranties, and upon such terms as shall be acceptable to Secured Party, all at
the sole option of and in the sole discretion of Secured Party.

          (B)  NOTICE OF SALE.  Secured Party shall give Grantor at least five
(5) days' prior written notice of sale of all or any party of the Pledged
Collateral.  Any sale of the Pledged Collateral shall be held at such time or
times and at such place or places as Secured Party may determine in the exercise
of its sole and absolute discretion.  Secured Party may bid (which bid may be,
in whole or in part, in the form of cancellation of Obligations) and purchase
for the account of Secured Party or any nominee of Secured Party the whole or
any part of the Pledged Collateral.  Secured Party shall not be obligated to
make any sale of the Pledged Collateral if it shall determine not to do so
regardless of the fact that notice of sale of the Pledged Collateral may have
been given.  Secured Party may, without notice or publication, adjourn the same
from time to time by announcement at the time and place fixed for sale, and such
sale may, without further notice, be made at the time and place to which the
same was so adjourned.

                                       5

<PAGE>

          (C)  PRIVATE SALES.  Whether or not any of the Pledged Collateral has
been effectively registered under the Securities Act of 1933 or other applicable
laws, Secured Party may, in its sole and absolute discretion, sell all or any
part of the Pledged Collateral at private sale in such manner and under such
circumstances as Secured Party may deem necessary or advisable in order that the
sale may be lawfully conducted.  Without limiting the foregoing, Secured Party
may:  (1) approach and negotiate with a limited number of potential purchasers;
and (2) restrict the prospective bidders or purchasers to persons who will
represent and agree that they are purchasing the Pledged Collateral for their
own account for investment and not with a view to the distribution or resale
thereof.  In the event that any of the Pledged Collateral is sold at private
sale, Grantor agrees that if the Pledged Collateral is sold for a price which
Secured Party in good faith believes to be reasonable, then: (a) the sale shall
be deemed to be commercially reasonable in all respects; (b) Grantor shall not
be entitled to a credit against the Obligations in an amount in excess of the
purchase price (less all expenses contemplated in Subsection (E) hereof); and
(c) Secured Party shall incur no liability or responsibility to Grantor in
connection therewith; notwithstanding the possibility that a substantially
higher price might have been realized at a public sale.  Grantor recognizes that
a ready market may not exist for Pledged Collateral which is not regularly
traded on a recognized securities exchange, and that a sale by Secured Party of
any such Pledged Collateral for an amount substantially less than a pro rata
share of the fair market value of the issuer's assets minus liabilities may be
commercially reasonable in a view of the difficulties that may be encountered in
attempting to sell a large amount of Pledged Collateral that is privately
traded.

          (D)  TITLE OF PURCHASERS.  Upon consummation of any sale of Pledged
Collateral pursuant to this Section, Secured Party shall have the right to
assign, transfer, and deliver to the purchaser or purchasers thereof the
Pledged Collateral so sold.  Each such purchaser at any such sale shall hold the
Pledged Collateral sold absolutely free from any claim or right on the part of
Grantor, and Grantor hereby waives (to the extent permitted by applicable laws)
all rights of redemption, stay, and appraisal which it now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted.  If the sale of all or any part of the Pledged Collateral is
made on credit or for future delivery, Secured Party shall not be required to
apply any portion of the sale price to the Obligations until such amount
actually is received by Secured Party, and any Pledged Collateral so sold may be
retained by Secured Party until the sale price is paid in full by the purchaser
or purchasers thereof.  Secured Party shall not incur any liability in case
any such purchaser or purchasers shall fail to pay for the Pledged Collateral so
sold, and, in case of any such failure, the Pledged Collateral may be sold
again upon like notice.

          (E)  DISPOSITION OF PROCEEDS OF SALE.  The net cash proceeds resulting
from the collection, liquidation, sale or other disposition of the Pledged
Collateral shall be applied:  (1) first, to the reasonable costs and expenses
(including reasonable attorneys' fees) of collecting, liquidating, selling or
otherwise disposing of the Pledged Collateral including, without limitation, all
costs and expenses of retaking, holding, storing, and preparing the Pledged
Collateral for sale; (2) second, to the satisfaction of all Obligations in such
order and manner as Secured Party in its sole and absolute discretion may
determine; and (3) to whomever shall be entitled thereto.

     SECTION 11  RELEASE OF GRANTOR.  This Agreement and all obligations of
Grantor hereunder shall be released when all Obligations have been paid in full
in cash or otherwise performed in full and when all Loan Documents have expired
or have otherwise been terminated.  Upon such release, Secured Party shall
return all Certificates representing the Pledged Collateral to the Grantor and
shall 

                                       6
 
<PAGE>

endorse, execute, deliver, record, and file all instruments and documents and do
all other acts and things, reasonably required for the return of the Pledged
Collateral to Grantor and to evidence or document the release of Secured Party's
interests arising under this Agreement, all as requested by, and/or at the
expense of Grantor.

     SECTION 12  EVIDENCE OF AUTHORITIES.  Grantor hereby consents and agrees
that the issuers of, or obligors on, or the partners or joint ventures with
respect to, the Pledged Collateral, or any registrar or transfer agent or
trustee for any of the Pledged Collateral, shall be entitled to accept the
provisions of this Agreement as conclusive evidence of the right of Secured
Party to effect any transfer or exercise any right hereunder, notwithstanding
any other notice or direction to the contrary heretofore or hereafter given by
Grantor or any other person to such issuers or such obligors or such partners
or joint venturers or to any such registrar or transfer agent or trustee.

     SECTION 13  COVENANT NOT TO ISSUE UNCERTIFICATED SECURITIES.  Grantor
represents and warrants to Secured Party that all of the capital stock granted
as security hereunder is in certificated form, and covenants to Secured Party
that it will not cause or permit the Companies to issue any capital stock in
uncertificated form or seek to convert all or any part of its existing capital
stock into uncertificated form.

     SECTION 14  GOVERNING LAW.  Except to the extent governed by applicable
Federal law, this Agreement shall be governed by and construed in accordance
with the laws of the State of Colorado.

     IN WITNESS WHEREOF, Grantor has caused this Agreement to be duly executed
as of the date first above written.

                               PLEDGE AGREEMENT

     THIS PLEDGE AGREEMENT (this "Agreement"), dated as of the 24th day of
January, 1997, is made by CG Member, Inc. ("Grantor") in favor of Colorado
Springs Production Credit Association ("Secured Party").


                                   BACKGROUND

     In order to induce Secured Party to make loans and other financial
accommodations available to Colorado Greenhouse, Inc. ("CGI"), a wholly-owned
subsidiary of Colorado Greenhouse Holdings, Inc. ("Holdings"), of which Grantor
is a wholly-owned subsidiary, and for the benefit of Colorado Greenhouse, LLC
("LLC"), a wholly-owned subsidiary of Grantor, and from which loans and other
financial accommodations Grantor expects to profit, this Agreement is hereby
made in favor of Secured Party to secure the payment and performance of the
Secured Obligations (hereinafter defined) of  CGI and LLC.

 
                                   AGREEMENT

     NOW, THEREFORE, in order to induce Secured Party to extend credit to CGI,
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledge, Grantor hereby represents, warrants, covenants,
agrees and pledges as follows:

     SECTION 1.  DEFINITIONS.  In addition to the terms defined elsewhere in
this Agreement, the following terms shall have the following meanings:

     LOAN DOCUMENTS shall have the meaning given to that term in the Master Loan
     Agreement.

     MEMBER INTERESTS shall mean all interests of Grantor in LLC, whether or not
     such interests are represented by certificates, and certificates,
     instruments or other documents, now or hereafter representing or evidencing
     any Pledged Securities.

     SECURED OBLIGATIONS shall mean (1) the payment and performance of all
     obligations of Holdings, CGI and LLC under the Master Loan Agreement,
     Construction Loan Supplement, LLCLoan Supplement, Line of Credit and all of
     the Loan Documents (as defined in the Master Loan Agreement) contemplated
     in all of the foregoing, whether now existing or hereafter arising; and (2)
     the payment of all other indebtedness and the performance of all other
     obligations of the Grantor to Secured Party of every type and description,
     whether now existing or hereafter arising, fixed or contingent, as primary
     obligor or as guarantor or surety, acquired directly or by assignment or
     otherwise, or liquidated or unliquidated.

     PLEDGED COLLATERAL shall mean the Pledged Securities, the Member Interests
     representing or evidencing the same, all right, title, interest,
     privileges, benefits, and preferences appertaining or incidental to such
     Pledged Securities, and any and all proceeds and products of the Pledged
     Securities (including, without limitation, all dividends, distributions,
     collections, redemption payments, liquidation payments, cash, and
     instruments).

                                       2
<PAGE>

     PLEDGED SECURITIES shall mean:  (1) the Member Interests; (2) any and all
     warrants, options or other rights to subscribe to or acquire any additional
     capital stock or member interests in such entity or entities; and (3) any
     and all securities, certificates, agreements, instruments or other
     documents now or hereafter issued in substitution, exchange or replacement
     of any of the foregoing or with respect thereto.

     SECTION 2.  CREATION OF SECURITY INTEREST.

          (A)  PLEDGE OF PLEDGED COLLATERAL.  As security for the Secured
Obligations, Grantor hereby pledges and grants to Secured Party a  interest in
and to the Pledged Collateral.

          (B)  DELIVERY OF CERTAIN PLEDGED COLLATERAL.  Simultaneously with the
execution hereof, Grantor shall cause to be pledged and delivered to Secured
Party such financing statements as may be necessary, in form and content
satisfactory to Secured Party which, in  its reasonable judgment, is  necessary
to perfect the security interest in the Pledged Collateral.

          (C)  NO MERGER.  In the event that Secured Party acquires the
ownership of the Pledged Collateral by exercise of the rights granted herein or
otherwise, such ownership interest shall not merge with the Secured Obligations,
and security interests granted in the Loan Documents shall remain in full force,
effectiveness and enforceability at the option of the Secured Party.

          (D)  CHANGE IN MANAGEMENT OF LLC.  Notwithstanding the pledge of the
Pledged Collateral and the other rights granted to Secured Party herein,
Secured Party agrees that in the event of Secured Party's election to exercise
its voting rights under Section 6(A) hereof, Secured Party will not remove or
replace the officers or directors of LLC or change their respective authority to
manage the affairs of LLC unless there shall be any amounts with respect to
Advances (as defined in the Line of Credit), interest or other obligations then
outstanding under the Line of Credit, and an "Event of Default" (as defined in
the Line of Credit) has occurred and is continuing under the LLC's Secured
Obligations with CGI.

     SECTION 3.  FURTHER ASSURANCES.  Grantor agrees that at any time, from time
to time, and at the expense of Grantor, Grantor will promptly execute, deliver,
and file or record such financing statements, instruments and documents, and
will take all further actions, that Secured Party may reasonably require in
order to:  (A) perfect and protect any pledge or security interest granted
hereby; (B) enable Secured Party to exercise and enforce Secured Party's rights
and remedies hereunder; and (C) preserve, protect, and maintain the Pledged
Collateral and the value thereof, including, without limitation, paying all
taxes, assessments, and other charges imposed on or relating to the Pledged
Collateral.

     SECTION 4.  WAIVER OF SURETY'S DEFENSES.  This Agreement, being in the
nature of an agreement of a surety, may give rise to certain defenses of a
surety or guarantor, which defenses Grantor intends to waive.  Wherefore,
Grantor acknowledges and agrees that this Agreement is an absolute and
independent obligation of the Grantor and therefore waives any right to require
that any action be brought against the borrower, another guarantor or any other
Person or entity which is liable for all or any part of the Secured Obligations,
or to require that resort be had at any time to any security for the Secured
Obligations or to any right of setoff or similar right.  The Grantor's
obligations hereunder shall be payable on demand and shall be absolute and
unconditional irrespective of (and the Grantor hereby expressly waives any
defense or claim of discharge based on): (i) the alteration or modification from
time to time (whether material or otherwise); (ii) the waiver by Secured Party
of the borrower's
 
<PAGE>

compliance with any of the terms and conditions of the Loan Documents; (iii) the
forbearance by Secured Party from exercising any right or remedy it may have
under the Loan Documents or under law; (iv) any inability, failure, neglect or
omission to obtain, perfect, maintain, enforce, or realize upon any collateral
for the Secured Obligations, or to pursue or obtain any deficiency judgment
against the borrower following any foreclosure of any security interest,
mortgage or deed of trust; (v) the loss or impairment of any collateral, the
subordination or release of Secured Party's Lien thereon, or the sale, pledge,
surrender, exchange or substitution of any collateral; (vi) Secured Party's
releasing, waiving, discharging, or modifying the obligations of one or more
other guarantors (whether a party hereto or to a separate agreement with Secured
Party); (vii) the acceptance by Secured Party of any partial payment on the
Secured Obligations or any collateral therefor, or Secured Party settling,
subordinating, compromising, discharging, or releasing the Secured Obligations
or any collateral therefor; (viii) the unenforceability of the Loan Documents;
(ix) any defenses or counterclaims assertable by the borrower, including any
defense or counterclaim based on failure of consideration, fraud, statute of
frauds, bankruptcy, statute of limitations, lender liability, and accord and
satisfaction; (x) any setoff, counterclaim, recoupment or similar right
assertable by the borrower, the Grantor, or other guarantor (whether a party
hereto or to a separate guarantee); or (xi) any other circumstance which
constitutes a legal or equitable discharge of a guarantor or surety. The Grantor
hereby agrees that all indebtedness and other obligations of the borrower (now
existing or hereafter incurred) to the Grantor are and shall be subordinated in
right of payment to the prior payment in full by the borrower of its obligations
to Secured Party under the Loan Documents. During the existence of a default
under the Loan Documents, no payments by the borrower shall be accepted by the
Grantor with respect to such subordinated obligations and, if any such payments
are inadvertently received, the same shall be held in trust and promptly turned
over to Secured Party. The Grantor hereby waives all claims, rights or remedies
that it may have at law or in equity (including, without limitation, any law
subrogating the Grantor to the rights of Secured Party) to seek contribution,
indemnification, or any other form of reimbursement from the borrower, any
other guarantor, or any other person or entity now or hereafter primarily or
secondarily liable for any obligations of the Grantor to Secured Party for any
disbursement made by the Grantor under or in connection with this Agreement or
otherwise. The Grantor hereby stipulates and agrees that any such disbursement
made by the Grantor shall be a contribution to the equity capital of the
borrower.

     SECTION 5.  GRANTOR'S VOTING RIGHTS; DIVIDENDS; ETC.  So long as no "Event
of Default" (as such term is defined in any Loan Document) occurs and remains
continuing:

          (A) VOTING RIGHTS.  Grantor shall be entitled to exercise any and all
voting and other consensual rights pertaining to the Pledged Securities, or any
part thereof, for any purpose not inconsistent with the terms of this
Agreement or the Loan Documents.

          (B) DIVIDEND AND DISTRIBUTION RIGHTS.  Grantor shall be entitled to
receive and to retain and use any and all dividends or distributions and all
cash or other property paid, payable or otherwise paid or distributed in respect
of the Pledged Securities; PROVIDED, HOWEVER, that any and all such dividends or
                           -----------------                                    
distributions received in the form of Member Interests, and the like shall be
delivered to the Secured Party to hold as Pledged Collateral and shall, if
received by Grantor, be received in trust for the benefit of Secured Party, be
segregated from the other property of the Grantor, and be forthwith delivered to
the Secured Party as Pledged Collateral in the same form as so received (with
any necessary endorsements).

                                       3

 
<PAGE>

     SECTION 6.  GRANTOR'S RIGHTS DURING EVENT OF DEFAULT.  When an Event of
Default has occurred and is continuing:

          (A) VOTING, DIVIDEND, AND DISTRIBUTION RIGHTS.  At the option of
Secured Party, all rights of Grantor to exercise the voting and other consensual
rights which would otherwise be entitled to exercise pursuant to Section 5(A)
above and to receive the dividends and distributions which it would otherwise be
authorized to receive and retain pursuant to Section 5(B) above, shall cease,
and all such rights shall thereupon become vested in Secured Party who shall
thereupon, but subject to Section 2(D), have the sole right to exercise such
voting and other consensual rights and to receive and to hold as Pledged
Collateral such dividends and distributions.  Secured Party shall, after
deciding to exercise voting rights with respect to the Pledged Collateral, give
notice thereof to Grantor; PROVIDED, HOWEVER, that: (1) neither the giving of
                           ------------------                                
such notice nor the receipt thereof by Grantor shall be a condition to exercise
of any rights of Secured Party hereunder; and (2) Secured Party shall incur no
liability for failing to give such notice.

          (B) DIVIDENDS AND DISTRIBUTIONS HELD IN TRUST.  All dividends and
other distributions which are received by Grantor contrary to the provisions
of this Agreement shall be received in trust for the benefit of Secured Party,
shall be segregated from other funds of Grantor, and shall be paid over to
Secured Party as Pledged Collateral in the same form as so received (with any
necessary endorsements).

     SECTION 7.  IRREVOCABLE PROXY.  Grantor hereby revokes all previous proxies
with regard to the Pledged Securities and appoints Secured Party as its
proxyholder to attend and vote at any and all meetings of the shareholders,
partners or other owners of the Companies held on or after the date of the
giving of this proxy and prior to the termination of this proxy, and to execute
any and all written consents of shareholders, partners or other owners of the
Companies executed on or after the date of the giving of this proxy and prior to
the termination of this proxy, with the same effect as if Grantor had personally
attended the meetings or had personally voted the Pledged Securities or had
personally signed the written consents; PROVIDED, HOWEVER, that the proxyholder
                                        -----------------                      
shall have rights hereunder only upon the occurrence and during the continuance
of an Event of Default and only in the event the Secured Party, as proxyholder,
has decided to exercise voting rights with respect to the Pledged Securities
or any of them and subject however to Section 2(D).  Grantor hereby authorizes
Secured Party to substitute another person as the proxyholder and, upon the
occurrence or during the continuance of any Event of Default, hereby authorizes
and directs the proxyholder to file this proxy and the substitution instrument
with the secretary (or other authorized official) of the Companies.  This proxy
is coupled with an interest and is irrevocable until such time as this Agreement
is released in accordance with Section 11 hereof.

     SECTION 8.  TRANSFERS AND OTHER LIENS.  Grantor agrees that it will not:
(A) sell, assign, exchange, transfer or otherwise dispose of, or contract to
sell, assign, exchange, transfer or otherwise dispose of, or grant any option
with respect to, any of the Pledged Collateral; (B) create or permit to exist
any lien or right of others upon or with respect to any of the Pledged
Collateral; or (C) take any action with respect to the Pledged Collateral which
is inconsistent with the provisions or purposes of this Agreement or any Loan
Document.

     SECTION 9.  SECURED PARTY APPOINTED ATTORNEY-IN-FACT.  Grantor hereby
irrevocably appoints the Secured Party as Grantor's attorney-in-fact, with full
authority in the place and stead of Grantor, 

                                       4

 
<PAGE>

and in the name of Grantor, or otherwise, from time to time, in Secured Party's
sole and absolute discretion, to do any of the following acts or things if
Grantor fails to do so promptly after demand by the Secured Party: (A) to do all
acts and things (including without limitation, the execution, filing and/or
recording of all financing statements and other documents) necessary or
advisable to perfect and continue perfected the security interests created by
this Agreement and to preserve, maintain, and protect the Pledged Collateral,
including, without limitation, the authority to pay, purchase, contest, and
compromise any lien or right of others which, in the reasonable judgment of
Secured Party, appears to be prior or superior to Secured Party's security
interests; (B) to do any and every act which Grantor is obligated to do under
this Agreement; and (C) to endorse and transfer the Pledged Collateral upon
foreclosure by the Secured Party; PROVIDED, HOWEVER, that Secured Party shall 
                                  -----------------
be under no obligation whatsoever to take any of the foregoing actions, and
Secured Party shall have no liability or responsibility for any act (other than
Secured Party's own gross negligence or willful misconduct) or omission taken
with respect thereto. Grantor hereby agrees to repay immediately upon demand all
reasonable costs and expenses incurred or expended by Secured Party in
exercising any right or taking any action under this Agreement, together with
interest at a rate per annum equal at all times to the Prime Rate as defined in
the Loan Documents.

     SECTION 10.  REASONABLE CARE.  Secured Party shall be deemed to have
exercised reasonable care in the custody and preservation of the Pledged
Collateral in its possession if the Pledged Collateral is accorded treatment
substantially equal to that which Secured Party accords its own property.
Notwithstanding the foregoing and whether or not an Event of Default has
occurred or is continuing, Secured Party shall be under no duty or obligation
to:  (A) exercise any voting or other rights with respect to the Pledged
Collateral; (B) make or give notices of default, presentments, demands for
performance, notices of nonperformance or dishonor, protests, notices of protest
or notices of any other nature whatsoever in connection with the Pledged
Collateral on behalf of Grantor or any other person having any interest therein;
(c) ascertain or take action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relative to any Pledged; or (D) take any
necessary steps to preserve rights against the Companies or any other person
with respect to any Pledged Collateral. In addition, Secured Party does not
assume and shall not be obligated to perform the obligations of Grantor, if any,
with respect to the Pledged Collateral.

     SECTION 11.  EVENTS OF DEFAULT AND REMEDIES.

          (A) RIGHTS UPON EVENT OF DEFAULT.  Upon the occurrence and during the
continuance of an Event of Default, Secured Party shall have, in any
jurisdiction where enforcement is sought, in addition to all other rights and
remedies that Secured Party may have under this Agreement and under applicable
law or in equity, all rights and remedies of a secured party under the Uniform
Commercial Code as enacted in any such jurisdiction, and in addition to the
following rights and remedies, all of which may be exercised with or without
further notice to Grantor, subject however to Section 2(D):

          (1) (a) to notify any issuer of any Pledged Securities, and any and
all other obligors on, or partners, joint ventures or other interested parties
with respect to, any Pledged Collateral, that the same has been pledged,
and/or that a security interest in the same has been granted, to Secured Party,
and that all dividends, distributions, and other payments thereon are to be made
directly and exclusively to Secured Party, and that all dividends,
distributions, and other payments thereon are to be made directly and
exclusively to Secured Party; (b) to renew, extend, modify, amend, accelerate,

                                       5

with respect to, release, settle, compromise, compound, collect or otherwise
liquidate, on terms acceptable to Secured Party, in whole or in part, the
Pledged Collateral and any amounts owing thereon or any guaranty or security
therefor; (c) to enter into any other agreement relating to or affecting the
Pledged Collateral; and (d) to give all consents, waivers, and ratifications
with respect to the Pledged Collateral and exercise all other rights (including
voting rights), powers and remedies and otherwise act with respect thereto as if
Secured Party were the owner thereof;

          (2) to enforce payment and prosecute any action or proceeding with
respect to any and all of the Pledged Collateral and take or bring, in Secured
Party's name or in the name of Grantor, all steps, actions, suits or proceedings
deemed by Secured Party necessary or desirable to effect collection of or to
realize upon the Pledged Collateral;

          (3) in accordance with applicable laws, to take possession of any
Pledged Collateral (with or without judicial process) that has not previously
been delivered to Secured Party;

          (4) to endorse, in the name of Grantor, all checks, notes, drafts,
money orders, instruments and other evidences of payment relating to the Pledged
Collateral;

          (5) to transfer any or all of the Pledged Collateral into the name of
Secured Party or its nominee or nominees; and

          (6) in accordance with applicable laws, to foreclose the liens and
security interests created under this Agreement or under any other agreement
relating to the Pledged Collateral by any available judicial procedure or

Pledged Collateral or any part thereof, either at public or private sale or at
any broker's board or securities exchange, in lots or in bulk, for cash, on
credit or for future delivery, or otherwise, with or without representations or
warranties, and upon such terms as shall be acceptable to Secured Party, all at
the sole option of and in the sole discretion of Secured Party, provided that
any purchaser of the Pledged Collateral shall take such Pledged Collateral
subject to limitations set forth in Section 2(D).

          (B) NOTICE OF SALE.  Secured Party shall give Grantor at least five
(5) days' prior written notice of sale of all or any party of the Pledged
Collateral.  Any sale of the Pledged Collateral shall be held at such time or
times and at such place or places as Secured Party may determine in the exercise
of its sole and absolute discretion.  Secured Party may bid (which bid may be,
in whole or in part, in the form of cancellation of the Secured Obligations) and
purchase for the account of Secured Party or any nominee of Secured Party the
whole or any part of the Pledged Collateral. Secured Party shall not be
obligated to make any sale of the Pledged Collateral if it shall determine not
to do so regardless of the fact that notice of sale of the Pledged Collateral
may have been given. Secured Party may, without notice or publication, adjourn
the same from time to time by announcement at the time and place fixed for sale,
and such sale may, without further notice, be made at the time and place to
which the same was so adjourned.

          (C) PRIVATE SALES.  Whether or not any of the Pledged Collateral has
been effectively registered under the Securities Act of 1933 or other applicable
laws, Secured Party may, in its sole and absolute discretion, sell all or any
part of the Pledged Collateral at private sale in such manner and under such
circumstances as Secured Party may deem necessary or advisable in order that the
sale

                                       6

 
<PAGE>

may be lawfully conducted.  Without limiting the foregoing, Secured Party may:
(1) approach and negotiate with a limited number of potential purchasers; and
(2) restrict the prospective bidders or purchasers to persons who will
represent and agree that they are purchasing the Pledged Collateral for their
own account for investment and not with a view to the distribution or resale
thereof.  In the event that any of the Pledged Collateral is sold at private
sale, Grantor agrees that if the Pledged Collateral is sold for a price which
Secured Party in good faith believes to be reasonable, then: (a) the sale shall
be deemed to be commercially reasonable in all respects; (b) Grantor shall not
be entitled to a credit against the Secured Obligations in an amount in excess
of the purchase price (less all expenses contemplated in Subsection (E)
hereof); and (c) Secured Party shall incur no liability or responsibility to
Grantor in connection therewith; notwithstanding the possibility that a
substantially higher price might have been realized at a public sale.  Grantor
recognizes that a ready market may not exist for Pledged Collateral which is not
regularly traded on a recognized securities exchange, and that a sale by Secured
Party of any such Pledged Collateral for an amount substantially less than a pro
rata share of the fair market value of the issuer's assets minus liabilities may
be commercially reasonable in a view of the difficulties that may be encountered
in attempting to sell a large amount of Pledged Collateral that is privately
traded.

          (D) TITLE OF PURCHASERS.  Upon consummation of any sale of Pledged
Collateral pursuant to this Section, Secured Party shall have the right to
assign, transfer, and deliver to the purchaser or purchasers thereof the
Pledged Collateral so sold.  Each such purchaser at any such sale shall hold the
Pledged Collateral sold absolutely free from any claim or right on the part of
Grantor, and Grantor hereby waives (to the extent permitted by applicable laws)
all rights of redemption, stay, and appraisal which it now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted, provided that any purchaser of the Pledged Collateral shall
take such Pledged Collateral subject to limitations set forth in Section 2(D).
If the sale of all or any part of the Pledged Collateral is made on credit or
for future delivery, Secured Party shall not be required to apply any portion of
the sale price to the Secured Obligations until such amount actually is received
by Secured Party, and any Pledged Collateral so sold may be retained by Secured
Party until the sale price is paid in full by the purchaser or purchasers
thereof.  Secured Party shall not incur any liability in case any such purchaser
or purchasers shall fail to pay for the Pledged Collateral so sold, and, in case
of any such failure, the Pledged Collateral may be sold again upon like notice.

          (E) DISPOSITION OF PROCEEDS OF SALE.  The net cash proceeds resulting
from the collection, liquidation, sale or other disposition of the Pledged
Collateral shall be applied:  (1) first, to the reasonable costs and expenses
(including reasonable attorneys' fees) of collecting, liquidating, selling or
otherwise disposing of the Pledged Collateral including, without limitation, all
costs and expenses of retaking, holding, storing, and preparing the Pledged
Collateral for sale; (2) second, to the satisfaction of all Secured Obligations
in such order and manner as Secured Party in its sole and absolute discretion
may determine; and (3) to whomever shall be entitled thereto.

     SECTION 12.  RELEASE OF GRANTOR.  This Agreement and all obligations of
Grantor hereunder shall be released when all Secured Obligations have been paid
in full in cash or otherwise performed in full and when all Loan Documents have
expired or have otherwise been terminated.  Upon such release, Secured Party
shall return all Certificates representing the Pledged Collateral to the Grantor
and shall endorse, execute, deliver, record, and file all instruments and
documents and do all other acts and things, reasonably required for the return
of the Pledged Collateral to Grantor and to evidence or document the release of
Secured Party's interests arising under this Agreement, all as requested by,
and/or at the expense of Grantor.

                                       7

     SECTION 13.  EVIDENCE OF AUTHORITIES.  Grantor hereby consents and agrees
that the issuers of, or obligors on, or the partners or joint ventures with
respect to, the Pledged Collateral, or any registrar or transfer agent or
trustee for any of the Pledged Collateral, shall be entitled to accept the 
provisions of this Agreement as conclusive evidence of the right of Secured
Party to effect any transfer or exercise any right hereunder, notwithstanding
any other notice or direction to the contrary heretofore or hereafter given by
Grantor or any other person to such issuers or such obligors or such partners or
joint venturers or to any such registrar or transfer agent or trustee.

     SECTION 14.  GOVERNING LAW.  Except to the extent governed by applicable
Federal law, this Agreement shall be governed by and construed in accordance
with the laws of the State of Colorado.

     IN WITNESS WHEREOF, Grantor has caused this Agreement to be duly executed
as of the date first above written.

                                JANUARY 24, 1997


================================================================================

<PAGE>
 
                           LINE OF CREDIT AGREEMENT

     THIS LINE OF CREDIT AGREEMENT (sometimes referred to herein as this
"Agreement" or in the Loan Documents as defined by the MLA as the "Line of
Credit") is made and entered into as of this 24th day of January, 1997, by and
between COLORADO GREENHOUSE, INC ("CGI") and COLORADO GREENHOUSE, LLC (the
"Borrower").

     SECTION 1.  THE LINE.  On the terms and conditions set forth herein, CGI
agrees to make Advances to Borrower during the period set forth below in any
aggregate principal amount not to exceed, at any one time outstanding, the
lesser of the "LLC Borrowing Base" (as calculated pursuant to the LLC Borrowing
Base Report attached hereto as Exhibit "A") or ONE MILLION FIVE HUNDRED THOUSAND
DOLLARS ($ 1,500,000) (the "Line").  Within the limits of the Line, Borrower may
borrow, repay and reborrow.

     SECTION 2.  TERM.  The term of the Line shall be from January 21, 1997, up
to and including December 31, 1997, or such later date as CGI may, in its sole
discretion, authorize in writing. Notwithstanding the foregoing, the Line shall
be automatically extended for an additional year unless on or before 90 days
prior to end of term in any year (the "Notification Date"), either party
receives written notice from the other to the contrary.  If on or before the
Notification Date, CGI grants a short-term extension of the Line, then the
Notification Date shall be extended for a like period, and in the event neither
party receives written notice from the other to the contrary on or before such
extended Notification Date (or any further extension so granted), then the Line
shall be automatically extended for an additional year as provided above.  All
annual extensions shall be measured from, and effective as of, the anniversary
date of the first day of the initial term of the Line.  Provided that there
shall be no amounts outstanding hereunder with respect to Advances, interest
thereon or other obligations hereunder, Borrower may, at any time, by written
notice to CGI terminate this Agreement and the commitments hereunder.

     SECTION 3.  PURPOSE.  The purpose of the Line is to finance the operating
needs of the Borrower, and the Borrower agrees to use the proceeds of the Line
for that purpose only.

     SECTION 4.  AVAILABILITY.  Advances under the Line may be made available on
any day that funds for such Advances are available to CGI.

     SECTION 5.  INTEREST.

          (A)    ADVANCES. Advances on the Line shall bear interest at the Prime
Rate, minus twenty-five (25) basis points (.25%). Prime Rate shall mean, for any
day, the rate defined as the "prime rate," as published from time to time in the
Eastern Edition of The Wall Street Journal as the average prime lending rate for
seventy-five percent (75%) of the United States' thirty (30) largest commercial
banks, or if The Wall Street Journal shall cease publishing the "prime rate" on
a regular basis, such other regularly published average prime rate application
to such commercial banks as is acceptable to CGI in its reasonable discretion.

          (B)    PAYMENT AND CALCULATION. Interest shall be payable on the 1st
day of each month beginning on the 1st day of the first month following the
first Advance hereon and shall be
<PAGE>
 
calculated on the number of days each Advance will be outstanding on the basis
of a year consisting of 365 days. In calculating interest, the date each Advance
is made shall be included and the date each Advance is repaid shall be excluded.

          (C)    DEFAULT RATE.  If prior to maturity the Borrower fails to make
any payment, at CGI's option in each instance, such payment shall bear interest
at four percent (4%) per annum in excess of the rate set forth in Subsection (A)
above.  After maturity, whether by reason of acceleration or otherwise, the
unpaid principal balance hereunder shall automatically bear interest at four
percent (4%) per annum in excess of the rates that would otherwise be in effect
(the "Default Rate").  All interest provided for in this Subsection shall be
payable on demand and shall be calculated from the date such payment was due to
the date paid on the basis of a year consisting of 365 days.

     SECTION 6.  NOTE.  The Borrower's obligation to repay the Advances shall be
evidenced by a promissory note in the form of Promissory Note attached hereto as
Exhibit "B" (the "Note").

     SECTION 7.  MANNER AND TIME OF PAYMENT.  The Borrower promises to repay the
Advances on the first business day following the last day of the term of the
Line ("Maturity Date"), all in accordance with the Note, and to pay interest on
the Advances in accordance with Section 5 above.

     SECTION 8.  SECURITY.  To secure the repayment of all Advances hereunder,
Borrower shall grant a security interest in the property more particularly
described in the Security Agreement of even date herewith, being all of
Borrower's interest in all Accounts, Inventory, Equipment, Fixtures, Farm
Products, General Intangibles, Chattel Paper, Instruments, Documents,
Intellectual Property (including without limitation the Trademarks and Logos
shown on Schedule 3 of the Security Agreement), and all products and proceeds
therefrom (the "Collateral"), subject only to the Trademark License Agreement
between CGI and Borrower.

     SECTION 9.  CONDITIONS PRECEDENT.  CGI's obligation to make the initial
Advance hereunder is subject to satisfaction of each of the following conditions
precedent on or before the date of the initial Advance:

          (A)    LOAN DOCUMENTS. That CGI receive duly executed originals of the
Agreement, the Note, and all other instruments and documents contemplated hereby
(this Agreement, the Note and such other instruments and documents, if any,
collectively, the "Loan Documents").

          (B)    AUTHORIZATION.  That CGI receive copies of all corporate
documents and proceedings of the Borrower authorizing the execution, delivery,
and performance of the Loan Documents, certified to be true and correct by a
Manager of the Borrower.

          (C)    APPROVALS. That CGI receive evidence satisfactory to it that
all consents and approvals which are necessary for, or required as a condition
of the validity and enforceability of the Loan Documents have been obtained and
are in full force and effect.

          (D)    EVENT OF DEFAULT.  That no Event of Default (as that term is
defined in Section 13 hereof) exists, and that there has occurred no event which
with the passage of time or the giving of notice, or both, could become an Event
of Default ("Potential Default").

                                       2

            (E)   CONTINUING REPRESENTATIONS AND WARRANTIES.  That the
representations and warranties of the Borrower contained in this Agreement be
true and correct on and as of the date of the initial Advance as though made on
and as of such date.

     SECTION 10.  REPRESENTATIONS AND WARRANTIES.  To induce CGI to make
Advances hereunder, and recognizing that CGI is relying hereon, the Borrower
represents and warrants as follows:

            (A)   ORGANIZATION; POWER; ETC.  The Borrower (i) is duly organized,
validly existing, and in good standing under the laws of its state of
incorporation; (ii) is duly qualified to do business and is in good standing in
each jurisdiction in which the transaction of its business makes such 
qualification necessary; (iii) has all requisite corporate and legal power to
own and operate its assets and to carry on its business and to enter into and
perform the Loan Documents; and (iv) has duly and lawfully obtained and
maintained all licenses, certificates, permits, authorizations, approvals, and
the like which are material to the conduct of its business or which may be
otherwise required by law.

            (B)   DUE AUTHORIZATION; NO VIOLATIONS; ETC.  The execution and
delivery by the Borrower of, and the performance by the Borrower of its
obligations under, the Loan Documents have been duly authorized by all requisite
limited liability company action on the part of the Borrower and do not and will
not (i) violate any provision of any law, rule or regulation, any judgment,
order or ruling of any court or governmental agency, the articles of
organization or operating agreement of the Borrower, or any agreement,
indenture, mortgage, or other instruments to which the Borrower is a party or by
which the Borrower or any of its properties is bound, including without
limitation any of the operation and management agreements under which it
occupies, operates and manages any of its greenhouse facilities, or (ii) be in
conflict with, result in a breach of, or constitute with the giving of notice or
lapse of time, or both, a default under any such agreement, indenture, mortgage,
or other instrument.  No action on the part of any member of the Borrower is
necessary in connection with the execution and delivery by the Borrower of and
the performance by the Borrower of its obligations under the Loan Documents.

            (C)   CONSENTS.  No consent, permission, authorization, order, or
license of any governmental authority is necessary in connection with the
execution, delivery, performance, or enforcement of the Loan Documents, except
such as have been obtained and are in full force and effect.

            (D)   BINDING AGREEMENT.  Each of the Loan Documents is, or when
executed and delivered will be, the legal, valid, and binding obligation of
the Borrower, enforceable in accordance with its terms, subject only to
limitations on enforceability imposed by applicable bankruptcy, insolvency,
reorganization, moratorium, or similar laws affecting creditors' rights
generally.

            (E)   COMPLIANCE WITH LAWS.  The Borrower is in compliance in all
material respects with all federal, state, and local laws, rules, regulations,
ordinances, codes, and orders (collectively, "Laws"), the failure to comply with
which could have a material adverse effect on the condition, financial or
otherwise, operations, properties, or business of the Borrower, or on the
ability of the Borrower to perform its obligations under the Loan Documents,
except as the Borrower has disclosed on Schedule 1 attached hereto.

            (F)   ENVIRONMENTAL COMPLIANCE.  Without limiting the provisions of
Subsection (E) above, all property owned or leased by the Borrower and all
operations conducted by it are in com-

                                       3
<PAGE>
 
pliance in all material respects with all Laws relating to environmental
protection, the failure to comply with which could have a material adverse
effect on the condition, financial or otherwise, operations, properties, or
business of the Borrower, or on the ability of the Borrower to perform its
obligations under the Loan Documents, except as the Borrower has disclosed on
Schedule 1 attached hereto.

          (G)     LITIGATION.  There are no pending legal, arbitration or
governmental actions or proceedings to which the Borrower is a party or to which
any of its property is subject which, if adversely determined, could have a
material adverse effect on the condition, financial or otherwise, operations,
properties, or business of the Borrower, or on the ability of the Borrower to
perform its obligations under the Loan Documents, and to the best of the
Borrower's knowledge, no such actions or proceedings are threatened or
contemplated, except as the Borrower has disclosed on Schedule 1 attached
hereto.

          (H)     TITLE TO PROPERTY. The Borrower has good and marketable title
to all of the property reflected in the financial statements referred to in
Subsection (1) below, free and clear of any lien, encumbrance, deed to secure
debt, deed of trust, mortgage, warrant, option, right to purchase, right of
first refusal or other lien or interest of any person or entity except (i) as
specifically disclosed in Schedule 1 attached hereto ("Existing Liens") and (ii)
liens or other interests permitted pursuant to Section 13 hereof.

          (I)     FINANCIAL STATEMENTS; NO MATERIAL ADVERSE CHANGE; ETC.  All
financial statements submitted to CGI in connection with the application for
the Line or in connection with this Agreement fairly and fully present the
financial condition of the Borrower and the results of the Borrower's operations
for the periods covered thereby, and are prepared in accordance with generally
accepted accounting principles ("GAAP") consistently applied.  Since the dates
thereof, there has been no material adverse change in the financial condition or
operations of the Borrower.  All budgets, projections, feasibility studies,
and other documentation submitted by the Borrower to CGI are based upon
assumptions that are reasonable and realistic, and as of the date hereof, no
fact has come to light, and no event or transaction has occurred, which would
cause any assumption made therein not to be reasonable or realistic.

          (J)     PRINCIPAL PLACE OF BUSINESS; RECORDS.  The principal place of
business and chief executive office of the Borrower and the place where the
records required by Section 11(G) hereof are kept is at the address of the

     SECTION 11.  AFFIRMATIVE COVENANTS.  Unless otherwise agreed to in writing
by CGI, while this Agreement is in effect, whether or not any Advance is
outstanding, the Borrower agrees to:

          (A)     LIMITED LIABILITY COMPANY EXISTENCE. Preserve and keep in full
force and effect its limited liability company existence and good standing in
the jurisdiction of its incorporation, and its qualification to transact
business and good standing in all places required by Law.

                                       4
<PAGE>
 
          (B)  COMPLIANCE WITH LAWS AND AGREEMENTS.  Comply in all material
respects with (i) all Laws, the failure to comply with which could have a
material adverse effect on the condition, financial or otherwise, operations,
properties or business of the Borrower or on the ability of the Borrower to
perform its obligations under the Loan Documents; and (ii) all agreements,
indentures, mortgages, and other instruments to which it is a party or by which
it or any of its property is bound, and under which it has the right to occupy,
operate and manage any of its greenhouse facilities.

          (C)  COMPLIANCE WITH ENVIRONMENTAL LAWS.  Without limiting the
provisions of Subsection (B) above, comply in all material respects with, and
cause all persons occupying or present on any properties owned or leased by the
Borrower to so comply with all Laws relating to environmental protection, the
failure to comply with which could have a material adverse effect on the 
condition, financial or otherwise, operations, properties, or business of the
Borrower, or on the ability of the Borrower to perform its obligations under the
Loan Documents.

          (D)  LICENSES; PERMITS; ETC.  Duly and lawfully obtain and maintain in
full force and effect all licenses, certificates, permits, authorizations,
approvals, and the like which are material to the conduct of the Borrower's
business or which may be otherwise required by Law.

          (E)  INSURANCE.  Maintain insurance with insurance companies or
associations acceptable to CGI in such amounts and covering such risks as are
usually carried by companies engaged in the same or similar business and
similarly situated, and make such increases in the type or amount of coverage as
CGI may request.  All such policies insuring any collateral provided for herein
shall provide for loss payable clauses or endorsements in form and content
acceptable to CGI.  At the request of CGI, certificates of insurance for all
policies (or such other proof of compliance with this Section as may be
satisfactory) shall be delivered to CGI.

          (F)  PROPERTY MAINTENANCE.  Maintain and preserve at all times its
property, and each and every part and parcel thereof, in good repair, working
order and condition and in compliance with all applicable Laws, regulations and
orders.

          (H)  INSPECTION.  Permit CGI or its agent, during normal business

operations, and accounts with its respective officers, directors, employees, and
independent certified public accountants.

containing an opinion acceptable to CGI; (iii) be prepared in reasonable detail
and in comparative form; and (iv) include a balance sheet, a statement of

          (3)  NOTICE OF DEFAULT.  Promptly after becoming aware thereof, notice
of (i) the occurrence of any Default, and (ii) the occurrence of any breach,
default, event of default, or event which with the giving of notice or lapse of
time, or both, could become a breach, default, or event of default under any
agreement, indenture, mortgage, or other instrument (other than the Loan 
Documents) to which it is a party or by which it or any of its property is bound
or affected if the effect of such breach, default, event of default or event is
to accelerate, or to permit the acceleration of, the maturity of any
indebtedness under such agreement, indenture, mortgage, or other instrument; 
provided, however, that the failure of the Borrower to give such notice shall
- --------  -------
not affect the right and power of CGI to exercise any and all of the remedies
specified herein.

          (4)  NOTICE OF NON-ENVIRONMENTAL LITIGATION.  Promptly after the
commencement thereof, notice of the commencement of all actions, suits, or
proceedings before any court, arbitrator, or governmental department,

claims personal injury or property damage to any person as a result of

Borrower to perform its obligations under the Loan Documents.

          (7)  MATERIAL ADVERSE CHANGE.  Prompt notice of any matter which has

seller of perishable agricultural commodities and (ii) shall not arise in
connection with its purchase of such commodities.

     SECTION 12.  NEGATIVE COVENANTS.  Unless otherwise agreed to in writing by
CGI, while this Agreement is in effect, whether or not any Advance is

          (A)     BORROWINGS. Create, incur, assume, or allow to exist, directly
or indirectly, any indebtedness or liability for borrowed money, for the

(15) days after written notice thereof shall have been delivered by CGI to the
Borrower, provided that if any default (except defaults of payment of money) can
be cured but cannot be cured within the respective cure period, it shall not be
deemed a default if actions to cure have been taken by Borrower within such cure
period and are diligently prosecuted to completion within thirty (30) days after
the end of the initial cure period.

          (D)     OTHER COVENANTS AND AGREEMENTS.  The Borrower should fail to

event of default, or event which with the giving of notice or lapse of time, or
both, could become a default or event of default under any agreement, indenture,

event is to accelerate, or to permit the acceleration of, the maturity of any
indebtedness under such agreement, indenture, mortgage, or other instrument.

otherwise, operations, properties, or business, or the Borrower's ability to
perform its obligations under the Loan Documents.

     SECTION 14.  REMEDIES.

          (A)     NO OBLIGATION TO MAKE ADVANCES. During the continuation of any
Default or upon the occurrence of and during the continuation of an Event of
Default, CGI shall have no obligation to make Advances hereunder.

terminate the Line and declare the entire unpaid principal balance of the Note,
all accrued interest thereon and all other amounts payable under this Agreement
and all other agreements between CGI and the Borrower, to be immediately due and
payable.  Upon such a declaration, the unpaid principal balance of the Note and

protest, presentation, demand, or further notice of any kind, all of which are
hereby expressly waived by the Borrower.

of any Event of Default, CGI may proceed to protect, exercise, and enforce such
rights and remedies as may be provided by agreement or under law, including

parte application, the appointment of a receiver for the Collateral without
regard to Borrower's financial condition or solvency, the adequacy of the
Collateral to secure the payment of Advances and the performance of the Loan
Documents, or the existence of any waste to the Collateral. Each and every one
of such rights and remedies shall be cumulative and may be exercised from time
to time, and no failure on the part of CGI to exercise, and no delay in
exercising, any right or remedy shall operate as a waiver thereof, nor shall any
single or partial exercise of any right or remedy preclude any other or future
exercise thereof, or the exercise of any other right.

          (D)     APPLICATION OF PAYMENTS. After termination and acceleration of
the Line, all amounts received by CGI shall be applied first to costs (including
CGI's reasonable attorney fees), then to interest, and then to principal, and
any remaining sums to be paid to other Persons as their interests may appear.

ONE MILLION FIVE HUNDRED THOUSAND DOLLARS                   January 24, 1997
$1,500,000.00                                             Loan No.__________

     FOR VALUE RECEIVED, the undersigned, Colorado Greenhouse, LLC, a Colorado
limited liability company (Maker"), hereby promises to pay to the order of
Colorado Greenhouse, Inc., a Delaware corporation doing business in Colorado,
("Payee"), at its offices, on the Maturity Date as defined in the Line of Credit
Agreement, in lawful money of the United States of America, the principal amount
of ONE MILLION FIVE HUNDRED THOUSAND DOLLARS ($1,500,000.00) or so much thereof
as may have been Advanced and is outstanding hereunder, together with interest
on the outstanding principal balance from day to day remaining, at the rate
provided in the Line Credit Agreement. All accrued and unpaid interest shall be
due and payable on the first day of each month beginning on the first day of the
first month following the first Advance hereon and on the Maturity Date. All
unpaid principal balance of the Advances on this Promissory Note shall be due
and payable on the Maturity Date. All past due principal shall bear interest at
the Default Rate.

     This Promissory Note has been given to Payee pursuant to the Line of Credit
dated as of the 24th day of January, 1997, and all capitalized terms used herein
and not otherwise defined shall have the meaning provided therein. Maker may
borrow, repay and reborrow hereunder and under the terms of the Line of Credit
Agreement.

     Upon the occurrence of any Event of Default, the holder hereof may, at its
option, declare the entire unpaid principal of and accrued interest on this
Promissory Note immediately due and payable without notice, demand or
presentment, all of which are hereby waived, and upon such declaration, the same
shall become and shall be immediately due and payable, and the holder hereof
shall have the right to foreclose or otherwise enforce all liens or security
interests securing payment hereof, or any part hereof, and offset against this
Promissory Note any sum or sums owed by the holder hereof to Maker. Failure of
the holder hereof to exercise this option shall not constitute a waiver of the
right to exercise the same upon the occurrence of a subsequent Event of Default.

     If the holder hereof expends any effort in any attempt to enforce payment
of all or any part of any sum due the holder hereunder, or if this Promissory
Note is placed in the hands of an attorney for collection, or if it is collected
through any legal proceedings, Maker agrees to pay all costs, expenses and fees
incurred by the holder, including reasonable attorney's fees.

     This Promissory Note shall be governed by and construed in accordance with
the Laws of the State of Colorado and the applicable Laws of the United States
of America.

     Maker and each surety, guarantor, endorser and other party ever liable for
payment of any sums of money payable on this Promissory Note jointly and
severally waive notice, presentment, demand for payment, protest, notice of
protest and non-payment or dishonor, notice of acceleration, notice of intent to
accelerate, notice of intent to demand, diligence in collecting, grace, and all
other formalities of any kind, and consent to all extensions without notice for
any period or periods of time and partial payments, before or after maturity,
and any impairment of any collateral securing this Promissory Note, all without
prejudice to the holder. The holder shall similarly have the right to deal in
any way, at any time, with one or more of the foregoing parties without notice
to any other party, and to grant any such party any extensions of time for
payment of any of said indebtedness, or to release or substitute any such party
or part or all of the collateral securing this Promissory Note, or to grant any
other indulgences or forbearances whatsoever, without notice to any other party
and without in any way affecting the personal liability of any party hereunder.

     Maker hereby authorizes the holder hereof to record in its records all
Advances made to Maker hereunder and all payments made on account of the
principal hereof and interest accruing hereon, which records shall be prima
facie evidence as to the outstanding principal amount of and interest accrued on
this Promissory Note; provided, however, any failure by the holder hereof to
make any records shall not limit or otherwise affect the obligations of Maker
under the Agreement or this Promissory Note.
