                                  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 75,000 pounds per acre for the quarter ended March 31, 1998, which
represents an approximately 19% increase from the same quarter in 1996.  The
Company also has increased its acreage by approximately 56% and increased its
net sales by approximately 104% 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 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"),

                                       4
<PAGE>
 
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 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 and although
at least part of the crop in Brush #1 was salvaged, the vines suffered hail
damage and a further decrease in production may result.  As a result of this
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.  The Company anticipates
that it will be able to recover under its insurance policy all of its property
damage (estimated to be $1.5 million) and most of its crop damage (estimated to
be $700,000) and loss of income (estimated to be $1.8 million) from the hail

  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 any dividends
distributed by Greenver.

(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.
(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 for 1997 is a weighted average based on the
    increase of total acres in production during the year as a result of the
    Estancia greenhouse, which began production in October 1998.

                                  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 only recently filed
claims on account of the hail storm in Brush and cannot predict when or whether
the insurance carriers will pay the entire amount of these claims.  The Company
also 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.  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
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

                                       9
<PAGE>
 
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 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. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Seasonality; Quarterly Results."

                                       10
<PAGE>
 
LACK OF CONTROL OVER TOMATO PRICES

  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."

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

                                       12
<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), Gargulio (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 Pennsylvania and Texas) and BC
Hothouse (with greenhouses in California).  The Company estimates that
worldwide, hydroponic greenhouse tomatoes currently originate from approximately
460 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

                                       13
<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 ___% 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 __________ 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 $5.89 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); (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 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.

                                    DILUTION

  The net tangible book value of the Company as of March 31, 1998, as adjusted
for the May 1998 Private Placement, conversion of all outstanding preferred
stock and the cashless exercise of the Warrant, was approximately $27.5 million
or $2.62 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 March 31, 1998 would have been
$57.5 million or $4.11 per share.  This represents an immediate increase in net
tangible book value of $1.49 per share to existing stockholders and an immediate
dilution in net tangible book value of $5.89 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:

                      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 75,000 pounds per
acre for the quarter ended March 31, 1998, which represents an approximately 19%
increase from the same quarter in 1996.  The Company also has increased its
acreage by approximately 56% and increased its net sales by approximately 104%
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 

                                       22
<PAGE>
 
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 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 at the Brush #1
and Brush #2 greenhouses. The Company anticipates that it will be able to
recover under its insurance policy all of its property damage and at least a
majority of its crop damage and lost profits from this hail storm, less
deductibles in the amount of $50,000.

  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%.

  THREE MONTHS ENDED MARCH 31, 1998 AND 1997

  Net Sales.  Net sales increased by $4.3 million, or 74.1%, to $10.1 million on
sales of 8.3 million pounds of tomatoes for the quarter ended March 31, 1998,
compared to net sales of $5.8 million on sales of 4.2 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
25% to 75,000 pounds per acre in the first quarter of 1998 from 60,000 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 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 $1.37 average sale
price per pound of tomatoes during the first quarter of 1997, compared to $1.21
for the comparable period in 1998.

  Gross Profit.  The Company's gross profit for the three months ended March 31,
1998 was $4.4 million, or 43.7% of net sales, compared to $1.6 million, or 27.6%
of net sales, for the three months ended March 31, 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 quarter of 1997.  Greenhouse
labor costs in the first quarter of 1997 were higher than normal as a result of
training expenses for additional greenhouse personnel.

  Operating Expenses.  During the quarter ended March 31, 1998, operating
expenses were $1.5 million, or 15.1% of net sales, compared to $1.1 million, or
18.8% of net sales, for the quarter ended March 31, 1997.  The components of the
dollar increase were: (i) a $0.2 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 74.1% increase in net sales during the
first quarter of 1998 caused the substantial decline in operating expenses as a
percentage of net sales.  Management expects that operating expenses may
increase as a percentage of net sales 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 $2.9
million, or 28.6% of net sales,  for the three months ended March 31, 1998,
compared to operating income of $0.5 million, or 8.7% of net sales, for the
comparable period in 1997.  This improvement resulted from the 74.1% increase in
net sales and the higher gross margin in the first quarter of 1998.

  Interest and Other Income (Expense), Net.  The Company incurred interest and
other expense of $0.1 million for the three months ended March 31, 1998,
compared to interest and other income of $41,000 for the three months ended
March 31, 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 $1.7 million, or 16.9%
of net sales, for the three months ended March 31, 1998, compared to a net
income of $0.3 million, or 5.9% of net sales, for the comparable period in 1997.
The Company's provision for income taxes was $1.0 million and $0.2 million for
the quarters ended March 31, 1997 and 1998, respectively, representing an
effective tax rate of 38% in both periods.

  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.

                                       24
<PAGE>
 
  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 $3.2 million at December
31, 1997, and March 31, 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 $1.0 million increase in cash flow from operations from the quarter ended
March 31, 1997 to the quarter ended March 31, 1998 was due primarily to the
substantial increase in operating income.  The $1.7 million decrease in
operating cash flow 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 operating cash flow 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 $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 $12.0 million decline in net cash provided by financing activities in the
first quarter of 1998 from the first quarter of 1997 was due to the $13.5 of net
proceeds from the sale of the Series B Convertible Preferred Stock in January
1997.  The $26.3 million increase in net cash provided by financing activities
from 1996 to 1997 was primarily from 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 1996, the Company made
distributions of $1.7 million to cover its LLC members' income tax obligations
on the Company's taxable income.

  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 nine-year term loan in May 1998, bearing interest at 8.19%
per annum.  At December 31, 1997, the balance on the construction loan was
approximately $11.0 million and increased to $12.2 million at March 31, 1998, as
a result of completion of construction of the Fort Lupton #2 greenhouse in
January 1998.

  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 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.  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."
(4) Average yield sold per acre for the quarter ended December 31, 1997 is a
    weighted average based on the increase of total acres in production during
    the year as a result of the Estancia greenhouse, which began production in
    October 1998.

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.  The Company also is
in the process of determining whether its major suppliers, service providers and
customers are year 2000 compliant.  The financial impact of Year 2000 compliance
to the Company is not anticipated to be material.

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 75,000 pounds per
acre for the quarter ended March 31, 1998, which represents an approximately 19%
increase from the same quarter in 1996.  The Company also has increased its
acreage by approximately 56% and increased its net sales by approximately 104%
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.

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 1996, 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 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 

                                       28
<PAGE>
 
to a consumer survey in the same produce industry trade journal, 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, driven by health and dietary concerns as well as by
changing tastes and the demographic profile of the U.S. population.  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:

                                       29
<PAGE>
 
  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.

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 

                                       30
<PAGE>
 
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 
    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."

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, a
Company sales representative works with the supermarket chain to tailor a sales
program to the customer's needs.  Each week, the sales representative quotes the
customer prices for the following week and the customer's program is filled 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 

                                       31
<PAGE>
 
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.

    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 

                                       32
<PAGE>
 
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 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, 

                                       33
<PAGE>
 
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.

  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 

                                       34
<PAGE>
 
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 approximately a 13% decline in total
production 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 

                                       35
<PAGE>
 
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 any dividends 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.  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, 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 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.
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 

                                       36
<PAGE>
 
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.

  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. 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), Gargulio (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 

                                       37
<PAGE>
 
in Arizona), Village Farms (with greenhouses in Pennsylvania and Texas) and BC
Hothouse (with greenhouses in California). The Company estimates that worldwide,
hydroponic greenhouse tomatoes currently originate from approximately 460 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, $853,089 for Brush #1, $1,042,169 for Brush #2 and $1,033,768 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) 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 $149,000 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

                                       38
<PAGE>
 
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.  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. 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, 

                                       45
<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.


                    CERTAIN TRANSACTIONS AND RELATIONSHIPS

  The LLC was organized in 1993 to take over operations of the Brush #1, Brush
#2 and Fort Lupton #1 greenhouses. Effective January 1, 1996, the LLC assumed
operation of the Rifle greenhouse.  The LLC has entered into Operating and
Management Agreements with the following entities (with the respective
greenhouse indicated):  BGP (Brush #1), BGPII (Brush #2), Rocky Mountain Produce
LLC (Fort Lupton #1) and Wolf Creek Rifle LLC (Rifle).

  Effective January 1, 1997, the Company and the LLC effected a reorganization,
by which the membership interests in the LLC held by BGP and BGPII were
exchanged for a total of 6,200,000 shares of the Company's Series A Preferred
Stock.  Colorado Power Partners ("CPP") and Brush Cogeneration Partners ("BCP")
own the Brush #1 and Brush #2 power projects and are under common control with
entities that own and control the related greenhouse lessee. Cogen Technology,
Inc. ("CTI") owns controlling interests in CPP and BCP.  American Atlas #1 L.P.
("AA#1"), an entity that has substantially the same equity ownership as CTI, is
the operator of the Rifle power plant, the sublessor of the Rifle greenhouse,
and controls Wolf Creek Rifle LLC.  The Company incurred rent expense for the
Brush #1 greenhouse of $853,099 in 1995, $853,094 in 1996 and $853,099 for 1997.
The Company incurred rent expense for the Brush #2 greenhouse of $853,099 in
1995, $900,378 in 1996 and $1,042,191 in 1997.  The Company incurred rent
expense for the Rifle greenhouse of $500,000 in 1996 and $500,000 in 1997.

  The following persons are involved in the management of these entities or the
parties involved in the development of the power projects:  R.C. Mercure, Jr. is
a limited partner of AA#1, owns 6.91% of the outstanding capital stock of CTI
and is the Company's Chairman of the Board.  Charles A. Hurth, Jr. is a limited
partner of AA#1, owns 4.24% of the outstanding capital stock of CTI and is a
director of the Company.  Edward J. Wetherbee owns 0.17% of the 

                                       46
<PAGE>
 
outstanding capital stock of CTI and is a director of the Company. Each of these
persons also is a beneficial owner of shares of the Company's Series A Preferred
Stock as a result of the reorganization of the LLC and the Company. See
"Principal Stockholders."

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
3,030,997 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."

<PAGE>
 
  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 Series B
Convertible Preferred Stock to override any demand registration request by the

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

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% 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.

                                       50
<PAGE>
 
  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 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 _________ 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 139,984 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 

                                       51

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.

  Subject to the terms and conditions of the Underwriting Agreement, the
underwriters named below (the "Underwriters"), through their representatives BT
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:

</TABLE>

  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.

                                       53

  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 at least $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.

  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.  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.

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. In
addition, 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

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.
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.

   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 $101,000, 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

                                      F-8
<PAGE>
 
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.

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 

                                      F-9
<PAGE>
 
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 Pronouncement
   ----------------------------

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.

                                      F-10
<PAGE>
 
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.

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

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 March 31, 1998, and for the three months ended
March 31, 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.

Due to the seasonal nature of the operations of the Company, the results of
operations for the three months ended March 31, 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 3rd 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 March 31, 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.
The unamortized amount of the prepaid rent as of December 31, 1996 and 1997, was
$341,000 and $299,000, respectively.

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.

(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):

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

effective January 1, 1994, and expire at various dates through 2019; the
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,

   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:

          Risk-free interest rate            6.47%           5.70%

          Expected life                2.64 years         3 years 
</TABLE>

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

   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.

The company anticipates that it will be able to recover, under its insurance
policy, most of its property damage, lost profits and crop damage, estimated to
be approximately $4 million.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

  Article VI of the Company's Amended and Restated Certificate  of Incorporation
and Article VI of the Company's Amended and Restated Bylaws, both to become
effective upon consummation of this offering,  provide that, to the fullest
extent permitted by the Delaware General Corporation Law ("DGCL"), directors of
the Company shall not be liable to the Company or any of its stockholders for
monetary damages for breach of a fiduciary duty by such director and further
provide that, to the fullest extent permitted by the DGCL, the Company may so
indemnify officers and other employees..

  Section 145 of the DGCL authorizes the indemnification of directors and
officers against liability incurred by reason of the fact that such person was a
director or officer and against expenses (including attorney's fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with defending any action seeking to establish such
liability if such person acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation.
Indemnification is also authorized with respect to any criminal action or
proceeding where the officer or director had no reasonable cause to believe his
conduct was unlawful.  No person shall be entitled to indemnification under the
DGCL, however, if such person shall have been adjudged to be liable to the
corporation unless the Court of Chancery or the court in which such action or
suit was brought determines that despite such adjudication of liability, such
person is fairly and reasonably entitled to indemnification.

  The above discussion of the Company's Certificate of Incorporation and Bylaws
and Section 145 of the Delaware General Corporation Law is intended to be only a
summary and is qualified in its entirety by the full text of each of the
foregoing.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

  Since the Company's formation in October 1996, the Company has issued the
following securities that were not registered under the Securities Act of 1933,
as amended (the "Securities Act").  Except as otherwise noted, no underwriters
were engaged in connection with any of the following transactions, and
accordingly, no underwriting discounts or commissions were paid. The shares of
capital stock and other securities issued in the following transactions were
offered and sold in reliance upon the following exemptions: (i) in the case of
the transactions described in (a), below, Section 4(2) of the Securities Act or
Regulation D promulgated thereunder relative to sales by an issuer not involving
a public offering; and (ii) in the case of the transactions described in (b),
below, Section 3(b) of the Securities Act and Rule 701 promulgated thereunder
relative to sales pursuant to certain compensatory benefits plans.

  (a) Issuances of Capital Stock:

     (i) On December 31, 1996 and January 2, 1997, the Company issued 6,200,000
shares of Series A Preferred Stock to Brush Greenhouse Partners and Brush
Greenhouse Partners II, LLC in exchange for all of the outstanding membership
interests of Colorado Greenhouse LLC, a Colorado limited liability company;
(ii) on January 21, 1997, the Company issued a total of 1,875,000 shares of
Series B Convertible Preferred Stock to Catterton-Simon Partners III, L.P.
(875,000 shares, $7,000,000 total purchase price), BCI Growth IV, L.P. (875,000
shares, $7,000,000 total purchase price), H&Q Colorado Greenhouse Investors, LLC
(93,750 shares, $750,000 total purchase price) and Catterton-CGH Partners,
L.L.C. (31,250 shares, $250,000 total purchase price).  In connection therewith,
Hambrecht & Quist, LLC was issued a warrant to purchase 18,500 shares of Series
B Convertible Preferred Stock at an exercise price of $8.00 per share and was
paid fees totaling $897,050; (iii) on May 8, 1998, the Company issued a total of
1,090,910 shares of Series C Convertible Preferred Stock for a total purchase
price of $6,000,000 to its existing preferred stockholders and their related
parties (as such term is defined in the Company's Shareholders Agreement).
Messrs. Rinella, Mercure, Hurth and Wetherbee all purchased shares of Series C
Convertible Preferred Stock in the May 8, 1998 offering.  These transactions
were completed without registration under the Securities Act of 1933 in reliance
on the exemption provided by Section 4(2) of the Securities Act of 1933.

  (b) Grants of Stock Options:

  On August 21, 1996, the Company issued to Company officers and employees stock
options to acquire a total of 557,495 shares of common stock of the Company at
an exercise price of $0.74, which the board of directors determined was the fair
market value of the Company's Common Stock at such time.  Options covering
52,794 shares of Common Stock have been exercised at a price per share of $0.74.
Of those options, options representing a total of 38,010 shares of Common Stock
were canceled and options were exercised to acquire a total of 52,794 shares of
Common Stock.  On September 15, 1997, the Company issued  to officers and
employees options to acquire a total of 140,000 shares of Common Stock at an
exercise price of $4.25 per share, which was the effective conversion price per
share to which the Company's Series B Preferred Stock were adjusted in September
1997 as a result of 1997 production problems.  On October 15 and 31, the Company
issued to newly employed officers options to acquire a total of 100,000 shares
and 250,000 shares, respectively, at an exercise price of $4.25.  On January 2,
1998, the Company issued options to acquire a total of 70,000 shares of Common
Stock to its then directors at an exercise price of $4.25 per share.

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 advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable.  In the event that a
claim for indemnification against such liabilities (other than the payment 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.

                (A)  In the event of any liquidation, dissolution or winding up
of the affairs of the Corporation, whether voluntary or involuntary, the holders
of the Series A Preferred Stock shall be entitled to receive, after the payment
of all preferential amounts required to be paid to the holders of any then-
existing senior series of Preferred Stock, out of the assets of the Corporation
available for distribution to its shareholders, if any, an amount equal to the
greater of (I) the Liquidation Price (as defined below), or (II) such amount per
share of Series A Preferred Stock as would have been payable had each such share

prior to such liquidation, dissolution or winding up of the affairs of the
Corporation (the greater of such amount or the Liquidation Price is referred to
hereafter as the "Series A Liquidation Amount"), and no more, before any payment

shall have the right, at their option, to convert shares of Series A Preferred
Stock into shares of Common Stock of the Corporation at any time and from time
to time on the following terms and conditions:

                (A) Each share of Series A Preferred Stock shall be converted at
the option of the holder thereof, without the payment of additional
consideration, into such number of fully paid and nonassessable shares of Common
Stock as is determined by dividing $3.00 by the Series A Conversion Rate (as
defined below) in effect at the time of conversion.  For purposes of this 
section, the "Series A Conversion Rate" initially shall be $3.00 and shall be 
              ------------------------
subject to adjustment as provided in Section 4.2(b)(iv)(D) below.

                (B) The Corporation shall not issue, in connection with the
conversion of shares of Series A Preferred Stock, certificates for fractional
shares, but in lieu thereof shall pay to any person who would otherwise be
entitled thereto an amount of cash equal to such fraction multiplied by the fair
value of one share of Common Stock, as determined by the board of directors,
whose determination shall be conclusive.

                (C) In order for any holder of shares of Series A Preferred
Stock to convert the same into Common Stock, he shall surrender the certificate
or certificates therefor, duly endorsed, at the office of the Corporation and
shall give written notice to the Corporation that he elects to convert all or
part of the shares represented by the certificate or certificates and shall
state in writing therein the name or names in which he wishes the certificate or
certificates for Common Stock to be issued. The Corporation shall, as soon as
practicable thereafter, issue and deliver to such holder of shares of Series A
Preferred Stock, or to his nominee or nominees, certificates for the full number
of shares of Common Stock to which he shall be entitled as aforesaid. Shares of
Series A Preferred Stock shall be deemed to have been converted as of the date
of the surrender of such shares for conversion as provided above, and the person
or persons entitled to receive Common Stock issuable upon such conversion shall
be treated for all purposes as the record holder or holders of such Common Stock
on such date.

                (D) The Series A Conversion Rate shall be subject to adjustment
as follows:

                    (I) In case the Corporation shall (i) pay a dividend or make
a distribution on its Common Stock in shares of Common Stock of the Corporation,
(ii) subdivide or split its outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, the Series A
Conversion Rate following the effective date of such event shall be equal to the
product of the Series A Conversion Rate in

                                       5
<PAGE>
 
effect immediately prior to such adjustment multiplied by a fraction, the
denominator of which is the number of shares of Common Stock outstanding
immediately after such event and the numerator of which is the number of shares
outstanding immediately prior to such event.

                    (II)   In the event the Corporation at any time or from time
to time shall make or issue, or fix a record date for the determination of
holders of Common Stock entitled to receive a dividend or other distribution
payable in securities of the Corporation other than shares of Common Stock, then
and in each such event provision shall be made so that the holders of Series A
Preferred Stock shall receive upon conversion thereof in addition to the number
of shares of Common Stock receivable thereupon, the amount of securities of the
Corporation that they would have received had Series A Preferred Stock been
converted into Common Stock on the date of such event and had they thereafter,
during the period from the date of such event to and including the conversion
date, retained such securities receivable by them as aforesaid during such
period, giving application to all adjustments called for during such period
under this section with respect to the rights of the holders of Series A
Preferred Stock; and provided further, however, that no such adjustment shall be
made if the holders of Series A Preferred Stock simultaneously receive a
dividend or other distribution of such securities as they would have received if
all outstanding shares of Series A Preferred Stock had been converted into
Common Stock on the date of such event.

                    (III)  If Common Stock issuable upon the conversion of
Series A Preferred Stock shall be changed into the same or a different number of
shares of any class or classes of stock, whether by capital reorganization,
reclassification, or otherwise (other than a subdivision or combination of
shares or stock dividend provided for above, or a reorganization, merger,
consolidation, or sale of assets provided for below), then and in each such
event the holder of each such share of Series A Preferred Stock shall have the
right thereafter to convert such share into the kind and amount of shares of
stock and other securities and property receivable upon such reorganization,
reclassification, or other change, by holders of the number of shares of Common
Stock into which such share of Series A Preferred Stock might have been
converted immediately prior to such reorganization, reclassification, or change,
all subject to further adjustment as provided herein.

                    (E)    Whenever the Series A Conversion Rate is adjusted as
herein provided, the Corporation shall prepare a certificate setting forth such
adjustment and showing in detail the facts upon which such adjustment is based,
and such certificate shall then be delivered to each holder of record of Series
A Preferred Stock.

                                       6
<PAGE>
 
                    (F) The adjustments herein provided for shall become
effective immediately following the record date for any event for which a record
date is designated and on the effective date for any other event.

                    (G) So long as any shares of Series A Preferred Stock remain
outstanding, and the holders thereof have the right to convert them into shares
of Common Stock, the Corporation shall reserve from the authorized and unissued
shares of its Common Stock a sufficient number of shares to provide for such
conversion.

                    (H) Shares of Series A Preferred Stock that have been
converted as provided herein shall revert to the status of authorized but
unissued shares of Preferred Stock.

                    (I) The holders of Series A Preferred Stock shall waive
their right to receive the preferred portion of accumulated but unpaid dividends
upon conversion.

          (v) Automatic Conversion. Each share of Series A Preferred Stock shall
              --------------------
automatically be converted into shares of the Corporation's common stock at the
Series A Conversion Rate (as adjusted) upon the closing of the sale of the
Corporation's Common Stock in a firm commitment, underwritten public offering

price (prior to underwriting commissions and expenses) of no less than $8.00 and

declared by the Corporation, equal to: (i) the number of shares of Common Equity

accrued and unpaid Equivalent Common Dividend shall be added to the Liquidation
Price, the Mandatory Redemption Price and the Redemption Price of the Series B
Preferred Stock effective at such due date when such Equivalent Common Dividend
was not paid.  If any accrued and unpaid Equivalent Common Dividend is so added
to the Liquidation Price, the Mandatory Redemption Price and the Redemption
Price of the Series B Preferred Stock, such Liquidation Price, Mandatory
Redemption Price and Redemption Price shall be reduced, effective on the date of
payment, to the extent any accrued and unpaid Equivalent Common Dividend is
subsequently paid.

          (B) So long as any shares of Series B Preferred Stock shall be
outstanding, the Corporation shall not declare, pay or set apart for payment on
any Subordinate Stock any dividends or distributions  whatsoever, whether in
cash, property or otherwise, nor shall any Subordinate Stock be purchased,
redeemed (except for the redemption of not more than 222,222 shares of
outstanding Series A Preferred Stock) or otherwise acquired by the Corporation

have been (i) paid or (ii) declared and a sum of money, in the case of dividends
payable in cash, sufficient for the payment thereof has been set apart.

          (C) In the event that full dividends are not paid or made available to
the holders of all outstanding shares of Series B Preferred Stock and funds
available for payment of dividends shall be insufficient to permit payment in
full to holders of all such stock of the full preferential amounts to which they
are then entitled, then the entire amount available for payment of dividends
shall be distributed ratably among all such holders of Series B Preferred Stock
in proportion to the full amount to which they would otherwise be respectively
entitled.

Series B Preferred Stock into shares of Common Stock. In the event of any such
Dissolution, before any payment or distribution shall be made to the holders of
Subordinate Stock, the holders of Series B Preferred Stock shall be entitled to
be paid out of the assets of the Corporation in cash, or, if the Corporation
does not have sufficient cash on hand to pay such amounts, property of the
Corporation at its fair market value as determined by the Board of Directors of
the Corporation, the greater of (i) the Liquidation Price per share of Series B
Preferred Stock, or (ii) such amount per share of Series B Preferred Stock as
would have been payable had each such share been converted into Common Stock
pursuant to Section 4.2(c)(iv) immediately prior to such Dissolution.
Immediately preceding such Dissolution, adjustment shall be made for accrued but
unpaid dividends.

           (B) If, upon any such liquidation, dissolution or other winding up of
the affairs of the Corporation, the assets of the Corporation shall be
insufficient to permit the payment in full of the Liquidation Price for each
share of the Series B Preferred Stock, then the assets of the Corporation shall
be ratably distributed among the holders of Series B Preferred Stock in
proportion to the full amounts to which they would otherwise be respectively
entitled if all amounts thereon were paid in full.

               (I)    At any time before the close of business on the Final
Mandatory Redemption Date (unless the Corporation shall default in payment of
the Redemption Price or the Delinquent Mandatory Redemption Price, in which
case, the conversion rights set forth in this paragraph shall continue until the
cure of any such default), each holder of Series B Preferred Stock may, at its
option, convert each share of Series B Preferred Stock held by such holder into
such number of shares of Common Stock determined by dividing $8.00 by $4.25,
subject to adjustment pursuant to Section 4.2(d)(iv)(C). Upon such conversion,
the rights of the holders of converted Series B Preferred Stock with respect to
the shares of Series B Preferred Stock so converted shall cease.

               (II)   To convert Series B Preferred Stock in accordance with 
this Section 4.2(c)(iv)(A), a holder must (i) surrender the certificate or
certificates evidencing the shares of Series B Preferred Stock to be converted,
duly endorsed in a form satisfactory to the Corporation, at the office of the

Corporation at such office that it elects to convert Series B Preferred Stock,
and the number of shares it wishes to convert; (iii) state in writing the name
or names in which it wishes the certificate or certificates for shares of Common
Stock to be issued, and (iv) pay any transfer or similar tax with respect to the
transfer of the shares of Series B Preferred Stock converted, if required.  The

Business Days of the Conversion Date, the Corporation shall deliver a
certificate for the number of shares of Common Stock issuable upon the
conversion, a check for the amount payable in respect of any fractional share
pursuant to Section 4.2(c)(iv)(A)(III) and a new certificate representing the
unconverted portion, if any, of the shares of Series B Preferred Stock
represented by the certificate or certificates surrendered for conversion.  The
person in whose name the Common Stock certificate is registered shall be treated
as the stockholder of record on and after the Conversion Date. Adjustment (or
cash payment, if applicable) shall be made for accrued and unpaid dividends, as
of the Conversion Date, on converted shares of Series B Preferred Stock.  If the
last day on which Series B Preferred Stock may be converted is not a Business
Day, Series B Preferred Stock may be surrendered for conversion on the next
succeeding day that is a Business Day.

               (III)  The Corporation will not issue a fractional share
of Common Stock upon conversion of Series B Preferred Stock.  Instead the
Corporation will deliver its check in an amount equal to the applicable fraction
multiplied by the fair market value of the Common Stock (subject to adjustment
for stock splits, subdivisions, combinations or other similar transactions).

               (IV)   If a holder converts shares of Series B Preferred Stock,
the Corporation shall pay any documentary, stamp or similar issue or transfer 
tax due on the issue of shares of Common Stock upon the conversion; provided,
                                                                    --------

such tax which is due because the shares are issued in a name other than the
holder's name.

          (B)  Mandatory Conversion.
               -------------------- 

     Each share of the Series B Preferred Stock shall be automatically
converted into such number of shares of Common Stock determined by dividing
$8.00 by $4.25, subject to adjustment pursuant to Section 4.2(d)(iv)(C), on the
date a Qualified Initial Public Offering is consummated ("Mandatory Conversion

Preferred Stock of such event: (ii) demand that all shares representing the
Series B Preferred Stock be returned to the Corporation's offices or to the
designated transfer agent; and (iii) pay any transfer or similar tax with

thirty (30) days after the Mandatory Conversion Date, the Corporation shall
deliver a certificate to and in the name of the holder of the Series B Preferred
Stock for the number of shares of Common Stock issuable upon the conversion and
a check in an amount calculated in accordance with Section 4.2(c)(iv)(A)(III)
for any fractional shares, if any, for the shares of Series B Preferred Stock
represented by the certificate.  The name of the person in which the Series B
Preferred Stock was issued shall be treated as the stockholder of record of the
Common Stock in which the Series B Preferred Stock was converted on and after
the Mandatory Conversion Date.  Adjustment (or cash payment, if applicable)
shall be made for accrued and previously declared and unpaid dividends, as of
the Mandatory Conversion Date, on shares of Series B Preferred Stock converted
pursuant to this Section 4.2(c)(iv)(B).  Upon such conversion, the rights of the
holders of converted Series B Preferred Stock with respect to the shares of
Series B Preferred Stock so converted shall cease.

          (C)  Certain Matters With Respect to Conversion.
               ------------------------------------------ 

               (I) The Corporation has reserved and shall continue to reserve
out of its authorized but unissued Common Stock or its Common Stock held in
treasury enough shares of Common Stock to permit the conversion of the Series B
Preferred Stock in full. All shares of Common Stock which may be issued upon
conversion of Series B Preferred Stock shall be duly authorized, validly issued,
fully paid and nonassessable. The Corporation shall comply with all securities
laws regulating the offer and delivery of shares

                                       16
<PAGE>
 
of common stock upon conversion of Series B Preferred Stock and will list such
shares on each national securities exchange on which the common stock is listed.

               (II)  If the Corporation:

                     (1) pays a dividend or makes a distribution on its Common
Stock or any other class of the Corporation's stock other than the Series B
Preferred Stock in shares of its Common Stock;

                     (2) subdivides its outstanding shares of Common Stock
into a greater number of shares;

                     (3) combines its outstanding shares of Common Stock into
a smaller number of shares;

                     (4) issues by reclassification of its Common Stock any
shares of its capital stock;

or effects any similar transaction, then an appropriate and proportionate
adjustment shall be made to the number of shares into which each share of Series
B Preferred Stock is convertible so that immediately after the occurrence of
such event the holders of Series B Preferred Stock shall be entitled to receive
the same percentage of the issued and outstanding Common Stock upon conversion
of the Series B Preferred Stock as such holders would have received if converted
immediately prior to such dividend, distribution, subdivision, combination or
reclassification.  The adjustment shall become effective immediately after the
record date in the case of a dividend or distribution and immediately after the
effective date of a subdivision, combination or reclassification.  Such
adjustment shall be made successively whenever any event listed above shall
occur.

               (III) If the corporation distributes any rights, options or war
rants to all holders of its Common Stock entitling them for a period expiring
within sixty (60) days after the record date mentioned below to purchase
additional shares of Common Stock at a price per share less than $4.25 (as
adjusted to reflect any stock split or any subdivision, reclassification,
combination of or with respect to outstanding shares of Common Stock or any
similar transaction) on that record date, the number of shares of Common Stock
into which each share of Series B Preferred Stock is convertible shall be If the
Corporation distributes any rights, options or war adjusted in accordance with
the following formula:

               Series B Preferred Stock is convertible after such distribution.
                
     O    =    the number of shares of Common Stock outstanding on the record
               date.

               Series B Preferred Stock was convertible prior to such
               distribution, which shall be determined immediately prior to the
               first adjustment pursuant to this Section 4.2(c)(iv)(C)(III) by
               dividing 8.00 by 4.25.

     A    =    the number of additional shares of Common Stock offered.

The adjustment shall be made successively whenever any such rights, options or
warrants are issued and shall become effective immediately after the record date
for the determination of stockholders entitled to receive the rights, option or
warrants. If at the end of the period during which such warrants, options or
rights are exercisable, not all warrants, options or rights shall have been
exercised, the number of shares of Common Stock into which each share of Series
B Preferred Stock is convertible shall be immediately readjusted to what it
would have been if "A" in the above formula had been the number of shares
actually issued. No adjustment shall be made pursuant to this Section
4.2(c)(iv)(C)(III) unless such adjustment results in a greater number of shares
of Common Stock issuable upon conversion of the Series B Preferred Stock.

               (IV) If the Corporation issues shares of Common Stock for a
consideration at a price less than $4.25 per share (as adjusted to reflect the
effect of any stock split or any subdivision, reclassification, combination of
or with respect to outstanding shares of Common Stock or any similar
transaction) on the date the Corporation fixes the offering price of such
additional shares, the number of shares of Common Stock into which each share of
Series B Preferred Stock is convertible shall be adjusted in accordance with the
following formula:

where:
 
     N'   =    the number of shares of Common Stock into which each share of
               Series B Preferred Stock is convertible after such issuance.

     N    =    the number of shares of Common Stock into which each share of
               Series B Preferred Stock was convertible prior to such issuance,
               which shall be determined immediately prior to the first issuance
               pursuant to this Section 4.2(c)(iv)(C)(IV) by dividing 8.00 by
               4.25.

     O    =    the number of shares of Common Stock outstanding immediately
               prior to the issuance of such additional shares.

     P    =    the aggregate consideration received for the issuance of such
               additional shares.

     M    =    $4.25.
 
     A    =    the number of shares outstanding immediately after the issuance
               of such additional shares.

The adjustment shall be made successively whenever any such issuance is made,
and shall become effective immediately after such issuance.  This Section
4.2(c)(iv)(C)(IV) does not apply to: (i) any transaction or issuance described
in Section 4.2(c)(iv)(C)(II) or Section 4.2(c)(iv)(C)(III) above or Section
4.2(c)(iv)(C)(V) below, including issuances of Common Stock pursuant to
warrants, options, rights or other convertible securities described in Section
4.2(c)(iv)(C)(III) and Section 4.2(c)(iv)(C)(V); (ii) the conversion of Series B
Preferred Stock, or the conversion, exchange or exercise of other securities
convertible into or exchangeable or exercisable for Common Stock; (iii) Common
Stock issued to the Corporation's employees under bona fide employee benefit
plans adopted by the Board of Directors of the Corporation and approved by the
holders of Common Stock when required by law, if such Common Stock would
otherwise be covered by this Section 4.2(c)(iv)(C)(IV) (but only to the extent
that the aggregate number of shares excluded hereby (together with the aggregate
number of shares issuable upon conversion, exchange or exercise of the
securities excluded by clause (iii) of Section 4.2(c)(iv)(C)(V) below) and
issued shall not

                                       19
<PAGE>
 
exceed 15% of the Common Stock of the Corporation on a fully diluted basis at
the time of any such issuance); or (iv) Common Stock issued in a Qualified
Initial Public Offering. No adjustment shall be made pursuant to this Section
4.2(c)(iv)(C)(IV) unless such adjustment results in a greater number of shares
of Common Stock issuable upon conversion of the Series B Preferred Stock.

               (V)  If the Corporation issues any options, warrants or other
securities convertible into or exchangeable or exercisable for Common Stock
(other than Series B Preferred Stock or securities issued in transactions
described in Section 4.2(c)(iv)(C)(III) above) for a consideration per share of
Common Stock initially deliverable upon conversion, exchange or exercise of such
securities of a price less than $4.25 per share of Common Stock (as adjusted to
reflect the effect of any stock split or any subdivision, reclassification,
combination of or with respect to outstanding shares of Common Stock or any
similar transaction) on the date of issuance of such securities, the number of
shares of Common Stock into which each share of Series B Preferred Stock is
convertible shall be adjusted in accordance with the following formula:
 
               N     x      (O+D)
              ---------------------   
     N'   =    O     +      P
                            -
                            M
 
where:
 
     N'   =    the number of shares of Common Stock into which each share of
               Series B Preferred Stock is convertible immediately after such
               issuance.
                
     N    =    the number of shares of Common Stock into which each share of
               Series B Preferred Stock was convertible immediately prior to
               such issuance, which shall be determined immediately prior to the
               first issuance pursuant to this Section 4.2(c)(iv)(C)(V) by
               dividing 8.00 by 4.25.
                
     O    =    the number of shares of Common Stock outstanding immediately
               prior to the issuance of such securities.

     P    =    the aggregate consideration received for the issuance of such
               securities.

     M    =    $4.25. 
 

                                       20

     D    =    the maximum number of shares deliverable upon conversion or in
               exchange for or upon exercise of such securities at the initial
               conversion, exchange or exercise rate.

     The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance. If all of the
Common Stock deliverable upon conversion, exchange or exercise of such
securities has not been issued when such securities are no longer outstanding,
then the number of shares of Common Stock into which each share of Series B
Preferred Stock is convertible shall promptly be readjusted to the basis of the
actual number of shares of Common Stock issued upon conversion, exchange or
exercise of such securities. This Section 4.2(c)(iv)(C)(V) does not apply to:
(i) the issuance of any such securities in a Qualified Initial Public Offering;
or (ii) the issuance of any such securities to the Corporation's employees under
bona fide employee benefit plans adopted by the Board of Directors of the
Corporation and approved by the holders of Common Stock when required by law, if
such securities would otherwise be covered by Section 4.2(c)(iv)(C)(V) (but only
to the extent that the aggregate number of shares issuable upon the conversion,
exchange or exercise of the aggregate number of securities excluded hereby
(together with the aggregate number of shares excluded by clause (iii) of
Section 4.2(c)(iv)(C)(IV) above) and issued shall not exceed 15% of the Common
Stock of the Corporation on a fully diluted basis at the time of any such
issuance). No adjustment shall be made pursuant to this Section
4.2(c)(iv)(C)(III)(V) unless such adjustment results in a greater number of
shares of Common Stock issuable upon conversion of the Series B Preferred Stock.

               (VI)   For the purpose hereof, the current market price per share
of any security on any date is the average of the Quoted Prices for thirty (30)
consecutive Trading Days commencing forty-five (45) Trading Days before the date
in question. If the Quoted Price is not ascertainable, the current market price
per share of any security on any date shall be the current market price as
determined by the Board of Directors of the Corporation in its reasonable
judgment exercised in good faith. Notwithstanding the foregoing, the current
market price per share of any security shall be deemed to be the greater of: (i)
the current market price as determined above; and (ii) the Liquidation Price.

               (VII)  For purposes of any computation of the number of shares of
Common Stock outstanding, such computation shall be made assuming conversion of
all then outstanding shares of Series A Preferred Stock and Series B Preferred
Stock and all outstanding currently exercisable warrants and vested options. For
purposes of any

                                       21
<PAGE>
 
computation respecting consideration received pursuant to Section
4.2(c)(iv)(C)(IV) and Section 4.2(c)(iv)(C)(V) above, the following shall apply:

                    (1)  in case of the issuance of shares of Common Stock for
cash, the consideration shall be the amount of such cash, provided that in no
case shall any deduction be made for any commissions, discounts or other
expenses incurred by the Corporation for any underwriting of the issue or
otherwise in connection therewith;

                    (2)  in the case of the issuance of shares of Common Stock
for a consideration in whole or in part other than cash, the consideration other
than cash shall be deemed to be the fair market value thereof as determined by
the Board of Directors of the Corporation in its reasonable judgment exercised
in good faith (irrespective of the accounting treatment thereof); and

                    (3)  in the case of the issuance of options, warrants or
other securities convertible into or exchangeable or exercisable for shares of
Common Stock, the aggregate consideration received therefor shall be deemed to
be the consideration received by the Corporation for the issuance of such
options, warrants or other securities plus the additional minimum consideration,
if any, to be received by the Corporation upon the conversion or exchange or
exercise thereof (the consideration in each case to be determined in the same
manner as provided in clauses (1) and (2) of this Section 4.2(c)(iv)(C)(VII).

          (VIII)    No adjustment in the number of shares of Common Stock into
which each share of Series B Preferred Stock is convertible need be made unless
the adjustment would require an increase or decrease of at least one-half of one
percent (.5%) in the number of shares of Common Stock into which each share of
Series B Preferred Stock is convertible. Any adjustments that are not made shall
be carried forward and taken into account in any subsequent adjustment. All
calculations under this Section 4.2(c)(iv)(C) shall be made to the nearest cent
or to the nearest 1/100th of a share, as the case may be.

          (IX)      No adjustment in the number of shares of Common Stock into
which each share of Series B Preferred Stock is convertible need be made under
this Section 4.2(c)(iv)(C) for: any change in the par value or no par value of
the Common Stock. If an adjustment is made to the number of shares of Common
Stock into which each share of Series B Preferred Stock is convertible upon the
establishment of a record date for a distribution subject to Section
4.2(c)(iv)(C) above and if such distribution is subsequently canceled, the
number of shares of Common Stock into which each share of Series B Preferred
Stock is convertible then in effect shall be readjusted, effective as of the
date when

                                       22
<PAGE>
 
the Board of Directors of the Corporation determines to cancel such
distribution, to the number of shares of Common Stock into which each share of
Series B Preferred Stock is convertible as would have been in effect if such
record date had not been fixed. No adjustment need be made under Section
4.2(c)(iv)(C) if the Corporation issues or distributes to each holder of Series
B Preferred Stock the shares of Common Stock, evidences of indebtedness, assets,
rights, options or warrants referred to in such paragraph which each holder
would have been entitled to receive had Series B Preferred Stock been converted
into Common Stock prior to or simultaneously with the happening of such event or
the record date with respect thereto.

               (X)  Whenever the number of shares of Common Stock into which
each share of Series B Preferred Stock is convertible is adjusted, the
Corporation shall promptly mail to holders of Series B Preferred Stock, first
class, postage prepaid, a notice of the adjustment. The Corporation shall file
with the transfer agent, if any, for Series B Preferred Stock a certificate from
the Corporation's independent public accountants briefly stating the facts
requiring the adjustment and the manner of computing it. Subject to Section
4.2(c)(iv)(C)(XIV) below, the certificate shall be conclusive evidence that the
adjustment is correct.

                    (XI) If:

                         (1)  the Corporation takes any action that would
require an adjustment pursuant to Section 4.2(c)(iv)(C);

                         (2)  the Corporation consolidates or merges with, or
transfers all or substantially all of its assets to, another corporation, and
stockholders of the Corporation must approve the transaction; or

                         (3)  there is a dissolution or liquidation of the
Corporation;

a holder of Series B Preferred Stock may want to convert such stock into shares
of Common Stock prior to the record date for or the effective date of the
transaction so that it may receive the rights, warrants, securities or assets
which a holder of shares of Common Stock on that date may receive. Therefore,
the Corporation shall mail to such holders, first class, postage prepaid, a
notice stating the proposed record or effective date, as the case may be. The
Corporation shall mail the notice at least thirty (30) days before such date.

                                       23
<PAGE>
 
               (XII)  If the Corporation is party to a consolidation or merger
which reclassifies or changes its Common Stock or to the sale of all or
substantially all of the assets of the Corporation, upon consummation of such
transaction the Series B Preferred Stock shall automatically become convertible
into the kind and amount of securities, cash or other assets which the holder of
Series B Preferred Stock would have owned immediately after the sale,
consolidation or merger, if such holder had converted Series B Preferred Stock
immediately before the effective date of the transaction, and an appropriate
adjustment (as determined by the Board of Directors of the Corporation) shall be
made in the application of the provisions herein set forth with respect to the
rights and interests thereafter of the holders of Series B Preferred Stock, to
the end that the provisions set forth herein (including provisions with respect
to changes in and other adjustment of the number of shares of Common Stock into
which each share of Series B Preferred Stock is convertible) shall thereafter be
applicable, as nearly as reasonably may be, in relation to any shares of stock
or other securities or property thereafter deliverable upon the conversion of
Series B Preferred Stock. If this Section 4.2(c)(iv)(C)(XII) applies, Section
4.2(c)(iv)(C)(II) - (V) do not apply.

               (XIII) In any case in which this Section 4.2(c)(iv)(C) shall
require that an adjustment as a result of any event become effective from and
after a record date, the Corporation may elect to defer until after the
occurrence of such event: (i) the issuance to the holder of any shares of Series
B Preferred Stock converted after such record date and before the occurrence of
such event of the additional shares of Common Stock issuable upon such
conversion over and above the shares issuable immediately prior to adjustment;
and (ii) the delivery of a check for any remaining fractional shares as provided
in Section 4.2(c)(iv)(A)(III) above.

               (XIV)  Except as provided in the immediately following sentence,
any determination that the Corporation or its Board of Directors must make
pursuant to this Section 4.2(c)(iv)(C) shall be conclusive. Whenever the
Corporation or its Board of Directors shall be required to make a determination
under this Section 4.2(c)(iv)(C), such determination shall be made in good faith
and may be challenged in good faith by the holders of a majority of the Series B
Preferred Stock, and any dispute shall be resolved promptly (and in no event
later than ninety (90) days after any challenge), at the Corporation's expense,
by an investment banking firm of recognized national standing selected by the
Corporation and acceptable to such holders of Series B Preferred Stock. Any such
determination shall be deemed approved if the requisite holders have not
notified the Corporation of any challenge within thirty (30) days after
receiving notice (including a statement in reasonable detail of the bases
therefor) of such determination.

               (XV)   Intentionally omitted.

                    (XVI)  The number of shares of Common Stock into which each
share of Series B Preferred Stock is convertible shall be adjusted, upon the
occurrence of a Liquidity Event, in accordance with the following formula:

               N'   =    N    -     [(N- 1.333) * E]

          where:

          N'   =    the number of shares of Common Stock into which each share
                    of Series B Preferred Stock is convertible immediately after
                    such Liquidity Event, provided, however, that, regardless of
                                          --------  -------
                    the determination of N'based on the calculations set forth
                    in this Section 4.2(c)(iv)(C)(XVI), in no event shall N' be
                    less than 1.333.

          N    =    the number of shares of Common Stock into which each share
                    of Series B Preferred Stock was convertible immediately
                    prior to such Liquidity Event.

          E    =    Adjustment Percentage.

               This adjustment shall be made in connection with the closing of a
          Liquidity Event but prior to any mandatory conversion of the Series B
          Preferred Stock.

          v.   Redemption by the Corporation.
               ----------------------------- 

               (A)  To the extent the Corporation shall have funds legally
available for such payment under the DGCL, the Corporation shall redeem, at the
option of each holder of shares of Series B Preferred Stock, on the date that is
five (5) years after the Initial Issue Date or, if such day is not a Business
Day, the next succeeding Business Day (the "Initial Mandatory Redemption Date"),
                                            ---------------------------------
a number of shares not to exceed fifty percent (50%) of the then outstanding
shares of Series B Preferred Stock of each holder at the Redemption Price. In
addition, to the extent the Corporation shall have funds legally available for
such payment under the DGCL, the Corporation shall redeem, at the option of each
holder of shares of Series B Preferred Stock, on the date that is six (6) years
after the Initial Issue Date or, if such day is not a Business Day, the next
succeeding Business Day (the "Final Mandatory Redemption Date"), up to one
                              -------------------------------
hundred percent (100%) of the then

                                       25
<PAGE>
 
outstanding shares of Series B Preferred Stock not subject to a redemption
obligation as of the Initial Mandatory Redemption Date at the Redemption Price.

          (B)  Shares of Series B Preferred Stock which have been issued and
converted or reacquired in any manner, including as a result of redemption,
shall (upon compliance with any applicable provisions of the Act) have the
status of authorized and unissued shares of the class of preferred stock of the
Corporation undesignated as to series, and may be redesignated and reissued as
part of any series of preferred stock of the Corporation; provided, however,
that no such issued and reacquired shares of Series B Preferred Stock shall be
reissued as Series B Preferred Stock.

          (C)  If on any Mandatory Redemption Date the Corporation is unable or
shall fail to discharge its obligation to redeem all outstanding shares of
Series B Preferred Stock required to be redeemed on such date pursuant to
Section 4.2(c)(v)(A) (the "Mandatory Redemption Obligation"), the Corporation
                           -------------------------------                   
shall redeem on such Mandatory Redemption Date the number of shares of Series B
Preferred Stock which it is able to redeem, ratably among the holders of Series
B Preferred Stock in proportion to the full amounts to which they would
otherwise be respectively entitled if all shares of Series B Preferred Stock
required to be redeemed on such date were redeemed.  In such a case, the
remainder of the Redemption Price payable but not paid at the Mandatory
Redemption Date shall be converted into a debt obligation of the Corporation,
evidenced by a promissory note in a form acceptable to the holders of Series B
Preferred Stock to pay the Delinquent Mandatory Redemption Price and shall be
discharged as soon as the Corporation is able to discharge such Delinquent
Mandatory Redemption Price out of funds legally available therefor.  If and so
long as any Mandatory Redemption Obligation (or any obligation in respect of the
Delinquent Mandatory Redemption Price) with respect to the Series B Preferred
Stock shall not be fully discharged and paid, the Corporation shall not declare
or pay any dividend or make any distribution on, or, directly or indirectly,
purchase, redeem or satisfy any mandatory redemption, sinking fund or other
similar obligation in respect of the Subordinate Stock (other than repurchases
of shares of Subordinate Stock in accordance with the terms of restricted stock
vesting agreements with employees of the Corporation approved by the Board of
Directors of the Corporation prior to such Mandatory Redemption Date).

          (D)  Notwithstanding the foregoing provisions of this Section
4.2(c)(v), unless the full cumulative dividends on all outstanding shares of
Series B Preferred Stock have been paid or contemporaneously are declared and
paid for all post dividend periods, none of the shares of Series B Preferred
Stock shall be redeemed or set aside for redemption, unless such shares of
Series B Preferred Stock subject to redemption are redeemed pro rata.

                                       26
<PAGE>
 
          (E)  Notice of any redemption shall be sent by or on behalf of the
Corporation not more than sixty (60) days nor less than thirty (30) days prior
to any Mandatory Redemption Date, by first class mail, postage prepaid, to all
holders of record of the Series B Preferred Stock at their respective last
addresses as they shall appear on the books of the Corporation; provided,
however, that no failure to give such notice or any defect therein or in the
mailing thereof shall affect the validity of the proceedings for the redemption
of any shares of Series B Preferred Stock except as to the holder to whom the
Corporation has failed to give notice or except as to the holder to whom notice
was defective. In addition to any information required by law or by the
applicable rules of any exchange upon which Series B Preferred Stock may be
listed or admitted to trading, such notice shall state: (i) the Mandatory
Redemption Date; (ii) the Redemption Price; (iii) the number of shares of Series
B Preferred Stock to be redeemed; (iv) the place or places where certificates
for such shares are to be surrendered for payment of the Redemption Price; (v)
that dividends on the shares to be redeemed will cease to accrue on the
Mandatory Redemption Date; (vii) the number of shares of Common Stock into which
each share of Series B Preferred Stock is convertible; (vii) that Series B
Preferred Stock called for redemption may be converted at any time before the
close of business on the Mandatory Redemption Date; and (viii) that holders of
Series B Preferred Stock must satisfy the requirements of Section
4.2(c)(iv)(A)(II) above if such holders desire to convert such shares. Upon the
mailing of any such notices of redemption, the Corporation shall become
obligated to redeem at the time of redemption specified therein all shares
called for redemption other than shares converted into Common Stock prior to the
Mandatory Redemption Date.

          (F)  If notice has been mailed in accordance with Section 4.2(c)(v)
above and provided that on or before the Mandatory Redemption Date specified in
such notice, all funds necessary for such redemption shall have been set aside
by the Corporation, separate and apart from its other funds in trust for the pro
rata benefit of the holders of the shares so called for redemption, so as to be,
and to continue to be available therefor, then, from and after the Mandatory
Redemption Date, dividends on the shares of the Series B Preferred Stock so
called for redemption shall cease to accrue, and said shares shall no longer be
deemed to be outstanding and shall not have the status of shares of Series B
Preferred Stock, and all rights of the holders thereof as shareholders of the
Corporation (except the right to receive from the Corporation the Redemption
Price) shall cease, irrespective of whether any certificates for shares called
for redemption have been surrendered to the Corporation. Upon surrender, in
accordance with said notice, of the certificates for any shares so redeemed
(properly endorsed or assigned for transfer), such shares shall be redeemed by
the Corporation at the Redemption Price and no holder of shares called for
redemption shall be entitled to receive payment of the Redemption Price therefor
until such surrender to the Corporation has been accomplished or a duly executed
affidavit

                                       27
<PAGE>
 
of lost certificate shall have been delivered to the Corporation. In case fewer
than all the shares represented by any such certificate are redeemed, a new
certificate or certificates shall be issued representing the unredeemed shares
without cost to the holder thereof (so long as such certificate is issued to the
holder).

          (G)  Any funds deposited with a bank or trust company for the purpose
of redeeming Series B Preferred Stock shall be irrevocable except that:

               (I)  the Corporation shall be entitled to receive from such bank
or trust company the interest or other earnings, if any, earned on any money so
deposited in trust, and the holders of any shares redeemed shall have no claim
to such interest or other earnings; and

               (II) any balance of monies so deposited by the Corporation and
unclaimed by the holders of the Series B Preferred Stock entitled thereto at the
expiration of two (2) years from the applicable Mandatory Redemption Date shall
be repaid, together with any interest or other earnings earned thereon, to the
Corporation, and after any such repayment, the holders of the shares entitled to
the funds so repaid to the Corporation shall look only to the Corporation for
payment without interest or other earnings.

          (H)  Notwithstanding anything to the contrary herein, no shares of
Series B Preferred Stock may be redeemed except with funds legally available
from the Corporation or any of its subsidiaries (including without limitation
the LLC) for the payment of the Redemption Price.

          (I)  In the event that the Corporation shall not have received the
Letters (as defined in the Stock Purchase Agreement) and delivered fully
executed copies thereof to the holders of the Series B Preferred Stock on or

               --------- 

               (A)  If at any time during which any shares of Series C Preferred
Stock remain outstanding, the Corporation declares, pays or sets apart for
payment any dividend on any Common Equity, whether in cash, property or
otherwise (a "Common Dividend"), each holder of shares of Series C Preferred
              ---------------
Stock shall be entitled receive a per share dividend (an "Equivalent Common
                                                          -----------------
Dividend"), when and as declared by the Corporation, equal to: (i) the number of
- --------
shares of Common Equity on which such Common Dividend is declared into which
each share of Series C Preferred Stock is convertible on the record date,
multiplied by (ii) the amount of cash or property paid, or the number of shares
- -------------
of capital stock issued, per share of Common Equity as part of such Common
Dividend. For any Equivalent Common Dividend that is not paid in full when due,
then on such due date such accrued and unpaid Equivalent Common Dividend shall
be added to the Liquidation Price, the Mandatory Redemption Price and the
Redemption Price of the Series C Preferred Stock effective at such due date when
such Equivalent Common Dividend was not paid. If any accrued and unpaid
Equivalent Common Dividend is so added to the Liquidation Price, the Mandatory
Redemption Price and the Redemption Price of the Series C Preferred Stock, such
Liquidation Price, Mandatory Redemption Price and Redemption Price shall be
reduced, effective on the date of payment, to the extent any accrued and unpaid
Equivalent Common Dividend is subsequently paid.

               (B)  So long as any shares of Series C Preferred Stock shall be
outstanding, the Corporation shall not declare, pay or set apart for payment on
any Subordinate Stock any dividends or distributions  whatsoever, whether in
cash, property or otherwise, nor shall any Subordinate Stock be purchased,
redeemed or otherwise acquired by the Corporation or any of its subsidiaries of
which it owns not less than a majority of the outstanding voting power, nor
shall any monies be paid or made available for a sinking fund for the purchase
or redemption of any Subordinate Stock, without the prior consent of a majority
of the outstanding shares of Series B Preferred Stock and Series C Preferred
Stock voting together as a single class, and unless all dividends to which the
holders of Series C Preferred Stock shall have been entitled shall have been (i)
paid or (ii) declared and a sum of money, in the case of dividends payable in
cash, sufficient for the payment thereof has been set apart.

                                       37
<PAGE>
 
               (C)  In the event that full dividends are not paid or made
available to the holders of all outstanding shares of Series B Preferred Stock
and Series C Preferred Stock and funds available for payment of dividends shall
be insufficient to permit payment in full to holders of all such stock of the
full preferential amounts to which they are then entitled, then the entire
amount available for payment of dividends shall be distributed ratably among all
such holders of Series B Preferred Stock and Series C Preferred Stock in
proportion to the full amount to which they would otherwise be respectively
entitled.

               (D)  Notwithstanding anything contained herein to the contrary,
no dividends on shares of Series C Preferred Stock shall be declared by the
Board of Directors of the Corporation or paid or set apart for payment by the
Corporation at such time if such declaration or payment shall be restricted or
prohibited by law.

        (iii)  Distributions Upon Liquidation, Dissolution or Winding Up.
               --------------------------------------------------------- 

               (A)  The Corporation shall deliver to each holder of Series C
Preferred Stock notice of any voluntary or involuntary liquidation, dissolution
or other winding up of the affairs of the Corporation (each a "Dissolution") at
least 90 days prior to such event, which notice shall state all material facts
and common terms relating to such Dissolution, including without limitation: (i)
the nature of such Dissolution, including without limitation the nature, amount,
terms and conditions of payment to the holders of Series C Preferred Stock and
Series B Preferred Stock and to the holders of Subordinate Stock in connection
with such Dissolution, (ii) the date on which such Dissolution shall occur and
(iii) the procedures that must be followed (and the latest date that such
procedures must be completed) in order for such holder to effect a conversion of
shares of Series C Preferred Stock into shares of Common Stock. In the event of
any such Dissolution, before any payment or distribution shall be made to the
holders of Subordinate Stock, the holders of Series C Preferred Stock shall be
entitled to be paid, pari passu with the holders of Series B Preferred Stock,
out of the assets of the Corporation in cash, or, if the Corporation does not
have sufficient cash on hand to pay such amounts, property of the Corporation at
its fair market value as determined by the Board of Directors of the
Corporation, the greater of (i) the Liquidation Price per share of Series C
Preferred Stock, or (ii) such amount per share of Series C Preferred Stock as
would have been payable had each such share been converted into Common Stock
pursuant to Section 4.2(d)(iv) immediately prior to such Dissolution.
Immediately preceding such Dissolution, adjustment shall be made for accrued but
unpaid dividends.

               (B)  If, upon any such Dissolution, the assets of the Corporation
shall be insufficient to permit the payment in full of the Liquidation Price for
each share of the Series C Preferred Stock and any liquidation price then
payable to the holders of the

                                       38
<PAGE>
 
Series B Preferred Stock, then the assets of the Corporation shall be ratably
distributed among the holders of Series C Preferred Stock and Series B Preferred
Stock, pari passu, in proportion to the full amounts to which such holders would
otherwise be respectively entitled if all amounts thereon were paid in full.

          (iv) Conversion Rights.
               ----------------- 

               (A)  Conversion at the Option of the Holder. At any time before
                    --------------------------------------
the close of business on the Final Mandatory Redemption Date (unless the
Corporation shall default in payment of the Redemption Price or the Delinquent
Mandatory Redemption Price, in which case, the conversion rights set forth in
this paragraph shall continue until the cure of any such default), the holders
of Series C Preferred Stock shall have the right to convert each share of Series
C Preferred Stock held by such holder into shares of Common Stock on the
following terms and conditions :

                    (I)  Each share of Series C Preferred Stock shall be
converted at the option of the holder thereof, without the payment of additional
consideration, into such number of fully paid and nonassessable shares of Common
Stock as is determined by dividing the Series C Initial Purchase Price by the
Series C Conversion Rate (as defined below) in effect at the time of conversion.
For purposes of this section, the "Series C Conversion Rate" initially shall be
                                   ------------------------
equal to the Series C Initial Purchase Price and shall be subject to adjustment
as provided in Section 4.2(d)(iv)(C) below.

                    (II) To convert Series C Preferred Stock in accordance with
this Section 4.2(d)(iv)(A), a holder must (i) surrender the certificate or
certificates evidencing the shares of Series C Preferred Stock to be converted,
duly endorsed in a form satisfactory to the Corporation, at the principal office
of the Corporation or transfer agent for the Series C Preferred Stock; (ii)
notify the Corporation in writing at such office that it elects to convert
Series C Preferred Stock, and the number of shares it wishes to convert; (iii)
state in writing the name or names in which it wishes the certificate or
certificates for shares of Common Stock to be issued, and (iv) pay any transfer
or similar tax with respect to the transfer of the shares of Series C Preferred
Stock to be converted, if required. The date on which the holder satisfies the
foregoing requirements shall be the "Conversion Date." As soon as practical but
                                     ---------------
in any event within five Business Days of the Conversion Date, the Corporation
shall deliver a certificate for the number of shares of Common Stock issuable
upon the conversion, a check for the amount payable in respect of any fractional
share pursuant to Section 4.2(d)(iv)(A)(III) and a new certificate representing
the unconverted portion, if any, of the shares of Series C Preferred Stock
represented by the certificate or certificates surrendered for conversion. The
person in whose name the Common Stock certificate is registered shall be treated
as the stockholder of record of such Common Stock

                                       39
<PAGE>
 
on and after the Conversion Date. Adjustment (or cash payment, if applicable)
shall be made for accrued and unpaid dividends, as of the Conversion Date, on
converted shares of Series C Preferred Stock. If the last day on which Series C
Preferred Stock may be converted is not a Business Day, Series C Preferred Stock
may be surrendered for conversion on the next succeeding day that is a Business
Day. Upon such conversion, the rights of the holders of converted Series C
Preferred Stock with respect to the shares of Series C Preferred Stock so
converted shall cease.

                    (III)  The Corporation will not issue a fractional share
of Common Stock upon conversion of Series C Preferred Stock.  Instead the
Corporation will deliver its check in an amount equal to the applicable fraction
multiplied by the fair market value of the Common Stock on the Conversion Date
as determined by the Corporation in its sole discretion (subject to adjustment
for stock splits, subdivisions, combinations or other similar transactions).

               (B)  Mandatory Conversion. Subject to the adjustments set forth
                    --------------------
in Section 4.2(d)(iv)(C), each share of the Series C Preferred Stock
automatically shall be converted into one share of Common Stock (subject to
adjustment pursuant to Section 4.2(d)(iv)(C)) on the date a Qualified Initial
Public Offering is consummated or upon the consent of 66 2/3% of the outstanding
shares of Series C Preferred Stock ("Mandatory Conversion Date"). At least 60
                                     -------------------------
days prior to the occurrence of the Mandatory Conversion Date, the Corporation
shall: (i) notify all holders of the Series C Preferred Stock of such event:
(ii) demand that all shares representing the Series C Preferred Stock be
returned to the Corporation's offices or to the designated transfer agent; and
(iii) pay any transfer or similar tax with respect to the conversion, if any. As
soon as practical but in any event within 30 days after the Mandatory Conversion
Date, the Corporation shall deliver a certificate to and in the name of the
holder of the Series C Preferred Stock for the number of shares of Common Stock
issuable upon the conversion and a check in an amount calculated in accordance
with Section 4.2(d)(iv)(A)(III) for any fractional shares, if any, for the
shares of Series C Preferred Stock represented by the certificate. The name of
the person in which the Series C Preferred Stock was issued shall be treated as
the stockholder of record of the Common Stock in which the Series C Preferred
Stock was converted on and after the Mandatory Conversion Date. Adjustment (or
cash payment, if applicable) shall be made for accrued and previously declared
and unpaid dividends, as of the Mandatory Conversion Date, on shares of Series C
Preferred Stock converted pursuant to this Section 4.2(d)(iv)(B). Upon such
conversion, the rights of the holders of converted Series C Preferred Stock with
respect to the shares of Series C Preferred Stock so converted shall cease.

               (C)  Certain Matters With Respect to Conversion.
                    ------------------------------------------ 

                                       40
<PAGE>
 
                    (I)  The Corporation has reserved and shall continue to
reserve out of its authorized but unissued Common Stock or its Common Stock held
in treasury enough shares of Common Stock to permit the conversion of the Series
C Preferred Stock in full. All shares of Common Stock which may be issued upon
conversion of Series C Preferred Stock shall be duly authorized, validly issued,
fully paid and nonassessable.

                    (II) The Series C Conversion Rate shall be subject to
adjustment as follows:

                         (1)  In case the Corporation shall (i) pay a dividend
or make a distribution on its outstanding shares of Common Stock, or any other
class of the corporation's stock other than Series B Preferred Stock or Series C
Preferred Stock, in shares of Common Stock of the Corporation, (ii) subdivide or
split its outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, the Series C Conversion Rate following
the effective date of such event shall be equal to the product of the Series C
Conversion Rate in effect immediately prior to such adjustment multiplied by a
fraction, the denominator of which is the number of shares of Common Stock
outstanding immediately after such event and the numerator of which is the
number of shares outstanding immediately prior to such event.

                         (2)  In the event the Corporation at any time or from
time to time shall make or issue, or fix a record date for the determination of
holders of Common Equity entitled to receive a dividend or other distribution
payable in securities of the Corporation other than shares of Common Stock, then
and in each such event provision shall be made so that the holders of Series C
Preferred Stock shall receive upon conversion thereof in addition to the number
of shares of Common Stock receivable thereupon, the amount of securities of the
Corporation that they each would have received had the Series C Preferred Stock
been converted into Common Stock on the date of such event and had they each
thereafter, during the period from the date of such event to and including the
conversion date, retained such securities receivable by them as aforesaid during
such period, giving application to all adjustments called for during such period
under this section with respect to the rights of the holders of Series C
Preferred Stock; provided, however, that no such adjustment shall be made if the
                 --------  -------
holders of Series C Preferred Stock simultaneously receive a dividend or other
distribution of such securities as they would have received if all outstanding
shares of Series C Preferred Stock had been converted into Common Stock on the
date of such event.

                         (3)  If Common Stock issuable upon the conversion of
Series C Preferred Stock shall be changed into the same or a different number of
shares of any class or classes of stock, whether by capital reorganization,
reclassification, or otherwise

                                       41
<PAGE>
 
(other than a subdivision or combination of shares or stock dividend provided
for above, or a reorganization, merger, consolidation, or sale of assets
provided for below), then and in each such event the holder of each such share
of Series C Preferred Stock shall have the right thereafter to convert such
share into the kind and amount of shares of stock and other securities and
property receivable upon such reorganization, reclassification, or other change,
by holders of the number of shares of Common Stock into which such share of
Series C Preferred Stock might have been converted immediately prior to such
reorganization, reclassification, or change, all subject to further adjustment
as provided herein.

                    (III)  Adjustments to the Series C Conversion Rate also
shall be made for certain dilutive issuances of additional shares of capital
stock by the Corporation as set forth in this Section 4.2(d)(iv)(C)(III).

                           (1)  Special Definitions. For purposes of this
                                -------------------
Section 4.2(d)(iv)(C)(III), the following definitions shall apply:

                                  (a) "Option" shall mean rights, options,
                                       ------
     warrants or other securities convertible into or exchangeable or
     exercisable for shares of Common Stock or Preferred Stock.

                                  (b) "Additional Shares of Stock" shall mean
                                       --------------------------
     all shares of Common Stock or Preferred Stock and all Options issued by the
     Corporation after the Initial Issue Date for which the consideration per
     share (determined pursuant to Section 4.2(d)(iv)(C)(III)(3) below) is less
     than the Series C Conversion Rate in effect on the date of, and immediately
     prior to, the issuance of such Additional Shares of Stock, other than
     shares of Common Stock or Preferred Stock issued or issuable:

                                      (i)   upon exercise of any Options
          outstanding on the Initial Issue Date; provided, however, that if the
                                                 --------  -------
          Corporation, after the Initial Issue Date, amends the exercise price
          or the number of shares covered by any Options outstanding on the
          Initial Issue Date, then such Options, as so amended, shall be deemed
          to have been issued after the Initial Issue Date;

                                      (ii)  by reason of a dividend, stock
          split, split-up or other distribution on shares of Common Stock that
          is covered by Section 4.2(d)(iv)(C)(II) above; or

                                       42
<PAGE>
 
                                      (iii) upon exercise of Options granted to
          employees or directors of, or consultants to, the Corporation pursuant
          to any Incentive or Non-Qualified Option Plan adopted by the
          Corporation's Board of Directors.

                             (2)  Adjustment of Series C Conversion Rate Upon
                                  -------------------------------------------
Issuance of Additional Shares of Stock. In the event the Corporation shall at
- --------------------------------------
any time issue one or more Additional Shares of Stock, then and in such event,
the Series C Conversion Rate shall be reduced, concurrently with such issuance,
to a price (calculated to the nearest cent) determined by multiplying the Series
C Conversion Rate then in effect by a fraction:

                                      (a)  the numerator of which shall be (i)
     the number of shares of Common Stock outstanding immediately prior to such
     issue plus (ii) the number of shares of Common Stock that the aggregate
     consideration received or to be received by the Corporation for the total
     number of Additional Shares of Stock so issued would purchase at such
     Series C Conversion Rate; and

                                      (b)  the denominator of which shall be
     the number of shares of Common Stock outstanding immediately prior to such
     issue plus the number of such Additional Shares of Stock so issued.

                             (3)  Determination of Consideration. For purposes
                                  ------------------------------ 
of this Section 4.2(d)(iv)(C)(III)(3), the consideration per share received by
the Corporation for the issue of any Additional Shares of Stock shall be
computed as follows:

                                      (a)  in case of the issuance of shares of
     Common Stock for cash, the consideration shall be the amount of such cash,
     provided that in no case shall any deduction be made for any commissions,
     discounts or other expenses incurred by the Corporation for any
     underwriting of the issue or otherwise in connection therewith;

                                      (b)  in the case of the issuance of shares
     of Common Stock for a consideration in whole or in part other than cash,
     the consideration other than cash shall be deemed to be the fair market
     value thereof as determined by the Board of Directors in its reasonable
     judgment exercised in good faith (irrespective of the accounting treatment
     thereof); and

                                      (c)  in the case of the issuance of
     Options, the aggregate consideration received therefor shall be deemed to
     be the

                                       43
<PAGE>
 
     consideration received by the Corporation for the issuance of such Options
     plus the additional minimum consideration, if any, to be received by the
     Corporation upon the conversion or exchange or exercise thereof (the
     consideration in each case to be determined in the same manner as provided
     in clauses (a) and (b) of this Section 4.2(d)(iv)(C)(III)(3)).

                         (IV)   Whenever the number of shares of Common Stock
into which each share of Series C Preferred Stock is convertible is adjusted,
the Corporation shall promptly mail to holders of the Series C Preferred Stock,
first class, postage prepaid, a notice of the adjustment. The Corporation shall
file with the transfer agent, if any, for the Series C Preferred Stock a
certificate from the Corporation's independent public accountants briefly
stating the facts requiring the adjustment and the manner of computing it. The
certificate shall be conclusive evidence that the adjustment is correct.

                         (V)    The adjustments herein provided for shall be
made successively when the event giving rise to such adjustment occurs and shall
become effective immediately following the record date for any event for which a
record date is designated and on the effective date for any other event.

                         (VI)   Shares of Series C Preferred Stock that have
been converted as provided herein shall revert to the status of authorized but
unissued shares of Series C Preferred Stock.

                         (VII)  For purposes of any computation of the number of
shares of Common Stock outstanding, such computation shall be made assuming
conversion of all then outstanding shares of all series of Preferred Stock and
exercise of all outstanding currently exercisable warrants and vested options.

                         (VIII) No adjustment in the Conversion Rate need be
made unless the adjustment would require an increase of at least one-half of one
percent (.5%) in the number of shares of Common Stock into which each share of
Series C Preferred Stock is convertible. Any adjustments that are not made shall
be carried forward and taken into account in any subsequent adjustment. All
calculations under this Section 4.2(d)(iv)(C) shall be made to the nearest cent
or to the nearest 1/100th of a share, as the case may be.

                         (XI)   In any case in which this Section 4.2(d)(iv)(C)
shall require that an adjustment as a result of any event become effective from
and after a record date, the Corporation may elect to defer until after the
occurrence of such event (a) the issuance to the holder of any shares of Series
C Preferred Stock converted after such record date and before the occurrence of
such event of the additional shares of Common Stock

                                       44
<PAGE>
 
issuable upon such conversion over and above the shares issuable immediately
prior to adjustment; and (b) the delivery of a check for any remaining
fractional shares as provided in Section 4.2(d)(iv)(A)(III) above.

                         (XII)  Any determination that the Corporation or its
Board of Directors must make pursuant to this Section 4.2(d)(iv)(C) shall be
conclusive.  Whenever the Corporation or its Board of Directors shall be
required to make a determination under this Section 4.2(d)(iv)(C), such
determination shall be made in good faith.

                         (XIII) If:

                                (1)  the Corporation takes any action that would
require an adjustment pursuant to Section 4.2(d)(iv);

                                (2)  the Corporation consolidates or merges
with, or transfers all or substantially all of its assets to, another
corporation, and stockholders of the Corporation must approve the transaction;
or

                                (3)  there is a dissolution or liquidation of
the Corporation; a holder of Series C Preferred Stock may want to convert such
stock into shares of Common Stock prior to the record date for or the effective
date of the transaction so that it may receive the rights, warrants, securities
or assets which a holder of shares of Common Stock on that date may receive.
Therefore, the Corporation shall mail to such holders, first class, postage
prepaid, a notice stating the proposed record or effective date, as the case may
be. The Corporation shall mail the notice at least thirty (30) days before such
date.

                         (XIV)  If the Corporation is party to a consolidation
or merger which reclassifies or changes its Common Stock or to the sale of all
or substantially all of the assets of the Corporation, upon consummation of such
transaction the Series C Preferred Stock shall automatically become convertible
into the kind and amount of securities, cash or other assets which the holder of
Series C Preferred Stock would have owned immediately after the sale,
consolidation or merger, if such holder had converted Series C Preferred Stock
immediately before the effective date of the transaction, and an appropriate
adjustment (as determined by the Board of Directors of the Corporation) shall be
made in the application of the provisions herein set forth with respect to the
rights and interests thereafter of the holders of Series C Preferred Stock, to
the end that the provisions set forth herein (including provisions with respect
to adjustment of the Conversion Rate) shall thereafter be applicable, as nearly
as reasonably may be, in relation to any shares of stock or other securities or
property thereafter deliverable upon the conversion of Series C Preferred Stock.
If this

                                       45
<PAGE>
 
Section 4.2(d)(iv)(C)(XIV) applies, Section 4.2(d)(iv)(C)(II) and
4.2(d)(iv)(C)(III) do not apply.

          (v)  Redemption by the Corporation.
               ----------------------------- 

               (A)  To the extent the Corporation shall have funds legally
available for such payment under the DGCL, the Corporation shall redeem, at the
option of each holder of shares of Series C Preferred Stock, on the Initial
Mandatory Redemption Date or, if such day is not a Business Day, the next
succeeding Business Day, a number of shares not to exceed fifty percent (50%) of
the then outstanding shares of Series C Preferred Stock of each holder at the
Redemption Price. In addition, to the extent the Corporation shall have funds
legally available for such payment under the DGCL, the Corporation shall redeem,
at the option of each holder of shares of Series C Preferred Stock, on the Final
Mandatory Redemption Date or, if such day is not a Business Day, the next
succeeding Business Day, up to one hundred percent (100%) of the then
outstanding shares of Series C Preferred Stock not subject to a redemption
obligation as of the Initial Mandatory Redemption Date at the Redemption Price.

               (B)  Shares of Series C Preferred Stock which have been issued
and converted or reacquired in any manner, including as a result of redemption,
shall (upon compliance with any applicable provisions of the Act) have the
status of authorized and unissued shares of preferred stock of the Corporation
undesignated as to series, and may be redesignated and reissued as part of any
series of preferred stock of the Corporation; provided, however, that no such
issued and reacquired shares of Series C Preferred Stock shall be reissued as
Series C Preferred Stock.

               (C)  If on any Mandatory Redemption Date the Corporation is
unable or shall fail to discharge its obligation to redeem all outstanding
shares of Series C Preferred Stock required to be redeemed on such date pursuant
to Section 4.2(d)(v)(A) (the "Mandatory Redemption Obligation"), the Corporation
                              -------------------------------
shall redeem on such Mandatory Redemption Date the number of shares of Series C
Preferred Stock which it is able to redeem, ratably among the holders of Series
C Preferred Stock in proportion to the full amounts to which they would
otherwise be respectively entitled if all shares of Series C Preferred Stock
required to be redeemed on such date were redeemed. In such a case, the
remainder of the Redemption Price payable but not paid at the Mandatory
Redemption Date shall be converted into a debt obligation of the Corporation,
evidenced by a promissory note in a form acceptable to the holders of Series C
Preferred Stock to pay the Delinquent Mandatory Redemption Price and shall be
discharged as soon as the Corporation is able to discharge such Delinquent
Mandatory Redemption Price out of funds legally available therefor. If and so
long as any Mandatory Redemption Obligation (or any obligation in

                                       46
<PAGE>
 
respect of the Delinquent Mandatory Redemption Price) with respect to the Series
C Preferred Stock shall not be fully discharged and paid, the Corporation shall
not declare or pay any dividend or make any distribution on, or, directly or
indirectly, purchase, redeem or satisfy any mandatory redemption, sinking fund
or other similar obligation in respect of the Subordinate Stock (other than
repurchases of shares of Subordinate Stock in accordance with the terms of
restricted stock vesting agreements with employees of the Corporation approved
by the Board of Directors of the Corporation prior to such Mandatory Redemption
Date).
               (D)  Notwithstanding the foregoing provisions of this Section
4.2(d)(v) unless the full cumulative dividends on all outstanding shares of
Series C Preferred Stock have been paid or contemporaneously are declared and
paid for all post dividend periods, none of the shares of Series C Preferred
Stock shall be redeemed or set aside for redemption, unless such shares of
Series C Preferred Stock subject to redemption are redeemed pro rata.

               (E)  Notice of any redemption shall be sent by or on behalf of
the Corporation not more than sixty (60) days nor less than thirty (30) days
prior to any Mandatory Redemption Date, by first class mail, postage prepaid, to
all holders of record of the Series C Preferred Stock at their respective last
addresses as they shall appear on the books of the Corporation; provided,
however, that no failure to give such notice or any defect therein or in the
mailing thereof shall affect the validity of the proceedings for the redemption
of any shares of Series C Preferred Stock except as to the holder to whom the
Corporation has failed to give notice or except as to the holder to whom notice
was defective. In addition to any information required by law or by the
applicable rules of any exchange upon which Series C Preferred Stock may be
listed or admitted to trading, such notice shall state: (i) the Mandatory
Redemption Date; (ii) the Redemption Price; (iii) the number of shares of Series
C Preferred Stock to be redeemed; (iv) the place or places where certificates
for such shares are to be surrendered for payment of the Redemption Price; (v)
that dividends on the shares to be redeemed will cease to accrue on the
Mandatory Redemption Date; (vii) the number of shares of Common Stock into which
each share of Series C Preferred Stock is convertible; (vii) that Series C
Preferred Stock called for redemption may be converted at any time before the
close of business on the Mandatory Redemption Date; and (viii) that holders of
Series C Preferred Stock must satisfy the requirements of Section
4.2(d)(iv)(A)(II) above if such holders desire to convert such shares. Upon the
mailing of any such notices of redemption, the Corporation shall become
obligated to redeem at the time of redemption specified therein all shares
called for redemption other than shares converted into Common Stock prior to the
Mandatory Redemption Date.

               (F)  If notice has been mailed in accordance with Section
4.2(d)(v)(E) above and provided that on or before the Mandatory Redemption Date
specified

                                       47
<PAGE>
 
in such notice, all funds necessary for such redemption shall have been set
aside by the Corporation, separate and apart from its other funds in trust for
the pro rata benefit of the holders of the shares so called for redemption, so
as to be, and to continue to be available therefor, then, from and after the
Mandatory Redemption Date, dividends on the shares of the Series C Preferred
Stock so called for redemption shall cease to accrue, and said shares shall no
longer be deemed to be outstanding and shall not have the status of shares of
Series C Preferred Stock, and all rights of the holders thereof as shareholders
of the Corporation (except the right to receive from the Corporation the
Redemption Price) shall cease, irrespective of whether any certificates for
shares called for redemption have been surrendered to the Corporation. Upon
surrender, in accordance with said notice, of the certificates for any shares so
redeemed (properly endorsed or assigned for transfer), such shares shall be
redeemed by the Corporation at the Redemption Price and no holder of shares
called for redemption shall be entitled to receive payment of the Redemption
Price therefor until such surrender to the Corporation has been accomplished or
a duly executed affidavit of lost certificate shall have been delivered to the
Corporation. In case fewer than all the shares represented by any such
certificate are redeemed, a new certificate or certificates shall be issued
representing the unredeemed shares without cost to the holder thereof (so long
as such certificate is issued to the record holder).

               (G)  Any funds deposited with a bank or trust company for the
purpose of redeeming Series C Preferred Stock shall be irrevocable except that:

                    (I)  the Corporation shall be entitled to receive from such
bank or trust company the interest or other earnings, if any, earned on any
money so deposited in trust, and the holders of any shares redeemed shall have
no claim to such interest or other earnings; and

                    (II) any balance of monies so deposited by the Corporation
and unclaimed by the holders of the Series C Preferred Stock entitled thereto at
the expiration of two (2) years from the applicable Mandatory Redemption Date
shall be repaid, together with any interest or other earnings earned thereon, to
the Corporation, and after any such repayment, the holders of the shares
entitled to the funds so repaid to the Corporation shall look only to the
Corporation for payment without interest or other earnings.

               (H)  Notwithstanding anything to the contrary herein, no shares
of Series C Preferred Stock may be redeemed except with funds legally available
from the Corporation or any of its subsidiaries (including without limitation
the LLC) for the payment of the Redemption Price.

          (vi) Voting Rights.

<PAGE>
 
               (A)  Each holder of Series C Preferred Stock shall have one vote
for each share (but not for any fractional share) of Common Stock that such
holder would be entitled to receive if he were to convert his shares of Series C
Preferred Stock into shares of Common Stock pursuant to Section 4.2(d)(iv)(A)
and shall have the right to vote on all matters in like manner as the holders of
the Common Stock. Except as may be otherwise required by law or set forth
herein, the holders of the Series C Preferred Stock shall at all times vote
together with the holders of the Common Stock as one class. Cumulative voting
shall not be allowed in the election of directors or for any other purpose.

               (B)  So long as at least 25% of the originally issued Series C
Preferred Stock remains outstanding, the Corporation cannot without the consent
of a majority of the holders of the then outstanding shares of the Series C
Preferred Stock voting as a single class either in writing without a meeting or
by vote at any meeting called for the purpose, effect, validate or permit:

                    (I)   any material or adverse amendment or alteration of the
rights and preferences of the Series C Preferred Stock;

                    (II)  any authorization, issuance or creation of, or
increase in the authorized amount of, any shares of any class or any security of
any class ranking senior to or in parity with the shares of Series C Preferred
Stock in the distribution of assets on any liquidation, dissolution or winding
up of the Corporation or in the payment of dividends; or

                    (III) any transaction or any act that would result in
taxation of the holders of Series C Preferred Stock under Section 305 of the
Internal Revenue Code.

          (vii)  Exclusion of Other Rights.  Except as may otherwise be
                 -------------------------                             
required by law, the shares of Series C Preferred Stock shall not have any
voting powers, preferences and relative, participating, optional or other
special rights, other than those specifically set forth in this Section 4.2(d)
(as such Section may be amended from time to time) and as otherwise set forth in
this Certificate of Incorporation.

          (viii) Headings of Subdivisions.  The headings of the various
                 ------------------------                              
subdivisions of this Section 4.2(d) are for convenience of reference only and
shall not affect the interpretation of any of the provisions hereof.

          (ix)   Severability of Provisions.  If any voting powers, preferences
                 --------------------------                                    
and relative, participating, optional and other special rights of the Series C
Preferred Stock and qualifications, limitations and restrictions thereof set
forth in this Section 4.2(d) (as such 

                                       49
<PAGE>
 
Section may be amended from time to time) is invalid, unlawful or incapable of
being enforced by reason of any rule of law or public policy, all other voting
powers, preferences and relative, participating, optional and other special
rights of Series C Preferred Stock and qualifications, limitations and
restrictions thereof set forth in this Section (as so amended) which can be
given effect without the invalid, unlawful or unenforceable voting powers,
preferences and relative, participating, optional and other special rights of
Series C Preferred Stock and qualifications, limitations and restrictions
thereof shall, nevertheless, remain in full force and effect, and no voting
powers, preferences and relative, participating, optional or other special
rights of Series C Preferred Stock and qualifications, limitations and
restrictions thereof herein set forth shall be deemed dependent upon any other
such voting powers, preferences and relative, participating, optional or other
special rights of Series C Preferred Stock and qualifications, limitations and
restrictions thereof unless so expressed herein.

     (e)  Issuance of Additional Preferred Stock.  Subject to the rights and
          --------------------------------------                            
preferences of any then-existing senior series of Preferred Stock, one or more
additional series of Preferred Stock may be created, authorized and issued by
the Board of Directors from time to time as hereafter provided.

          The Board of Directors is hereby expressly authorized, by resolution
from time to time adopted providing for the issuance of Preferred Stock, to fix
and state the designations, powers, preferences and relative, optional and other
special rights of the shares of each series of Preferred Stock, and the
qualifications, limitations and restrictions thereof, including (but without
limiting the generality of the foregoing) any of the following with respect to
which the Board of Directors shall determine to make effective provisions:

          (i)   the distinctive name and serial designation;

          (ii)  the dividend payment dates;

          (iii) the rate or rates at which dividends, if any, shall be paid;

          (iv)  whether dividends are to be cumulative or non-cumulative and any
preferential or other special rights with respect to the payment of dividends;

          (v)   whether any series shall be redeemable and, if so, the terms,
conditions and manner of redemption and the redemption price or prices;

                                       50
<PAGE>
 
          (vi)   the rights of a series on voluntary or involuntary liquidation,
dissolution or winding up, including the amount or amounts of preferential or
other payment to which any series is entitled over any other series or over the
Common Stock;

          (vii)  any sinking fund or other retirement  provisions and the
extent to which the charges therefor are to have priority over the payment of
dividends on or the making of sinking fund or other like retirement provisions
for shares of any other series or over dividends on the Common Stock;

          (viii) the number of shares of such series;

          (ix)   the voting rights, if any, for such series;  and

          (x)    the conversion rights, if any, for such series.

         Unless otherwise provided in the resolution of the Board of Directors
providing for the issue thereof, shares of any series of Preferred Stock which
shall be issued and thereafter acquired by the Corporation through purchase,
redemption, conversion or otherwise, may by resolution of the Board of Directors
be returned to the status of authorized but unissued Preferred Stock of the same
or other series.  Unless otherwise provided in the resolution of the Board of
Directors providing for the issue thereof, the number of authorized shares of
stock of any such series may be increased or decreased (but not below the number
of shares thereof then outstanding) by resolution of the Board of Directors.  In
case the number of shares of any such series of Preferred Stock shall be
decreased, the shares representing such decrease shall, unless otherwise
provided in the resolution of the Board of Directors providing for the issuance
thereof, resume the status of authorized but unissued Preferred Stock,
undesignated as to series.

                            LIMITATION ON LIABILITY

          To the fullest extent permitted by the Delaware General Corporation
Law, as the same exists or may hereafter be amended, a director of the
Corporation shall not be liable to the Corporation or its stockholders for

modification of this Article by the stockholders of the Corporation shall be
prospective only and shall not adversely affect any right or protection of a
director of the Corporation existing at the time of such repeal or modification.

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

time to time determine or as the business of the corporation may require.

      Section 2.01  Annual Meeting.  An annual meeting of the stockholders shall
                    --------------                                              
be held on such date and at such time as the board of directors shall fix in the
notice of meeting, beginning with the year 1997, for the purpose of electing
directors and for the transaction of such other business as may come before the
meeting.  If the day fixed for the annual meeting shall be a legal holiday, such
meeting shall be held on the next succeeding business day.  If the election of
directors shall not be held on the day designated herein for any annual meeting
of the stockholders, or at any adjournment thereof, the board of directors shall
cause the election to be held at a meeting of the stockholders as soon
thereafter as conveniently may be.  Failure to hold an annual meeting as
required by these bylaws shall not invalidate any action taken by the board of
directors or officers of the corporation.

      Section 2.02  Special Meetings.  Special meetings of the stockholders, for
                    ----------------

      Section 2.03  Place of Meeting.  Each meeting of the stockholders shall be
                    ----------------                                            
held at such place, either within or outside Delaware, as may be designated in
the notice of meeting, or, if no place is designated in the notice, at the
principal office of the corporation.

      Section 2.04  Notice of Meetings.  Except as otherwise required by law,
                    ------------------                                       
written notice of each meeting of the stockholders stating the place, day and
hour of the meeting and, in the case of a special meeting, the purpose or
purposes for which the meeting is called, shall be given, either personally
(including delivery by private courier) or by first class, certified or
registered mail, to each stockholder of record entitled to notice of such
meeting, not less than ten nor more than 60 days before the date of the meeting.
Such notice shall be deemed to be given, if personally delivered, when delivered
to the stockholder, and, if mailed, when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation, but if notice of two consecutive annual meetings and
all notices of meetings of or the taking of action by written consent without a
meeting to any stockholder during the period between such two consecutive annual
meetings, or all, and at least two, payments (if sent by first class mail) of
dividends or interest on securities during a 12-month period, have been mailed
addressed to such person at his address as shown on the records of the
corporation and have been returned undeliverable, the giving of such notice to
such person shall not be required until another address for such person is
delivered to the corporation.  When a meeting is adjourned to another time or
place, notice need not be given of the adjourned meeting if the time and place
thereof are announced at the meeting at which the adjournment is taken.  At the
adjourned meeting the corporation may transact any business that might have been
transacted at the original meeting.  If the adjournment is for more than 30
days, or if after the adjournment a new record date is fixed for the adjourned
meeting, notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote at the meeting in accordance with the foregoing
provisions of this Section 2.04.

      Section 2.05  Fixing Date for Determination of  Stockholders of Record.
                    --------------------------------------------------------  
For the purpose of determining stockholders entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, or entitled to receive
payment of any dividend or other distribution or allotment of any rights, or
entitled to exercise any rights in respect of any change, conversion or exchange
of stock or for any other lawful action, the board of directors may fix, in
advance, a date as the record date for any such determination of stockholders,
which date shall be not more than 60 nor less than ten days before the date of
such meeting, and not more than 60 days prior to any other action.  If no record
date is fixed for determining stockholders entitled to notice of or to vote at a
meeting of stockholders, then the record date shall be the close of business on
the day next preceding the day on which notice is given, or, if notice is
waived, the close of business on the day next preceding the day on which the
meeting is held, or, for determining stockholders for any other purpose, the
close of business on the day on which the board of directors adopts the
resolution relating thereto.  A determination of stockholders of record entitled
to notice of or to vote at a meeting of stockholders shall apply to any
adjournment of the meeting; provided, however, that the board of directors may
fix a new record date for the adjourned meeting.  Notwithstanding the foregoing
provisions of this Section 2.05, the record

                                      -2-
<PAGE>
 
date for determining stockholders entitled to take, or receive notice of,
corporate action in writing without a meeting as provided in Section 2.11 shall
be determined as provided in such Section.

      Section 2.06  Voting List.  The officer who has charge of the stock books
                    -----------                                                
of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
the meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present.

      Section 2.07  Proxies.  Each stockholder entitled to vote at a meeting of
                    -------                                                    
stockholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period.

      Section 2.08  Quorum and Manner of Acting.  At all meetings of
                    ---------------------------                     
stockholders, a majority of the outstanding shares of the corporation entitled
to vote, represented in person or by proxy, shall constitute a quorum.  If a
quorum is present, the affirmative vote of a majority of the shares represented
at a meeting and entitled to vote on the subject matter shall be the act of the
stockholders, unless the vote of a greater proportion or number or voting by
classes is otherwise required by law, the certificate of incorporation or these
bylaws.  In the absence of a quorum, a majority of the shares so represented may
adjourn the meeting from time to time in accordance with Section 2.04, until a
quorum shall be present or represented.

      Section 2.09  Voting of Shares.  Unless otherwise provided in the
                    ----------------                                   
certificate of incorporation and subject to the provisions of Section 2.05, each
stockholder entitled to vote shall have one vote for each outstanding share of
capital stock held of record by such stockholder on each matter submitted to a
vote of the stockholders either at a meeting thereof or pursuant to Section
2.11.  In the election of directors each record holder of stock entitled to vote
at such election shall have the right to vote the number of shares owned by him
for as many persons as there are directors to be elected, and for whose election
he has the right to vote.  Cumulative voting shall not be allowed.  If a
separate vote by a class or classes is required, a majority of the outstanding
shares of such class or classes, present in person or represented by proxy,
shall constitute a quorum entitled to take action with respect to that vote on
that matter and the affirmative vote of the majority of shares of such class or
classes present in person or represented by proxy at the meeting shall be the
act of such class.

      Section 2.10  Voting of Shares by Certain Holders.
                    ----------------------------------- 

           (a)      Fiduciaries; Pledgors.  Persons holding stock in a fiduciary
                    ---------------------                                       
capacity shall be entitled to vote the shares so held.  Persons whose stock is
pledged shall be entitled to vote,

                                      -3-
<PAGE>
 
unless in the transfer by the pledgor on the books of the corporation he has
expressly empowered the pledgee to vote thereon, in which case only the pledgee
or his proxy may represent such shares and vote thereon.

          (b)       Joint Owners. If shares stand of record in the names of two
                    ------------
or more persons, whether fiduciaries, members of a partnership, joint tenants,
tenants in common, tenants by the entirety or otherwise, or if two or more
persons have the same fiduciary relationship respecting the same shares, unless
the secretary of the corporation is given written notice to the contrary and is
furnished with a copy of the instrument or order appointing them or creating the
relationship wherein it is so provided, their acts with respect to voting shall
have the following effects: (i) if only one votes, his act binds all; (ii) if
more than one votes, the act of the majority so voting binds all; and (iii) if
more than one votes, but the vote is evenly split on any particular matter, each
faction may vote the shares in question proportionally, or any person voting the
shares, or a beneficiary, if any, may apply to any court having jurisdiction to
appoint an additional person to act with the persons so voting the shares, in
which case the shares shall then be voted as determined by a majority of such
persons. If the secretary of the corporation is given notice and is furnished a
copy of the instrument or order creating a tenancy held in unequal interests, a
majority or even split for the purpose of subparagraph (iii) shall be a majority
or even split in interest.

     Section 2.11   Action Without a Meeting.
                    ------------------------ 

          (a)       Written Consent. Unless otherwise provided in the
                    ---------------
certificate of incorporation, any action required or permitted to be taken at
any meeting of the stockholders may be taken without a meeting, without prior
notice and without a vote, if a consent in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted (which consent may be signed in counterparts). Every written consent
shall bear the date of signature of each stockholder who signs the consent and
no written consent shall be effective to take the corporate action referred to
therein unless, within 60 days of the earliest dated consent delivered to the
corporation in the manner required by the Delaware General Corporation Law,
written consents signed by a sufficient number of stockholders to take the
action are delivered to the corporation in the manner required by the Delaware
General Corporation Law.

          (b)       Determination of Stockholders Entitled to Act By Consent.
                    --------------------------------------------------------   
For purposes of determining stockholders entitled to consent to corporate action
in writing without a meeting, the board of directors may fix, in advance, a date
as the record date for any such determination of stockholders, which date shall
be not more than ten days after the date upon which the resolution fixing the
record date is adopted by the board of directors. If no record date has been
fixed by the board of directors, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting, when no
prior action by the board of directors is required by the Delaware General
Corporation Law, shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
corporation in the manner required by the Delaware General Corporation Law. If
no record date

                                      -4-
<PAGE>
 
has been fixed by the board of directors and prior action by the board of
directors is required by the Delaware General Corporation Law, the record date
for determining stockholders entitled to consent to corporate action in writing
without a meeting shall be the close of business on the day on which the board
of directors adopts the resolution taking such prior action.

          (c)       Notice to Non-Consenting Stockholders. Prompt written notice
                    -------------------------------------
of the taking of corporate action without a meeting by less than unanimous
written consent shall be given to those stockholders who have not consented in
writing. Such notice shall be given in accordance with the applicable provisions
of Section 2.04.


                                  ARTICLE III

                              Board of Directors

      Section 3.01  General Powers.  The business and affairs of the corporation
                    --------------                                              
shall be managed by or under the direction of its board of directors, except as
otherwise provided in the Delaware General Corporation Law or the certificate of
incorporation.

      Section 3.02  Number, Tenure and Qualifications.  The number of directors
                    ---------------------------------                          
of the corporation shall be as fixed from time to time by resolution of the
board of directors.  Except as otherwise provided in Sections 2.01 and 3.05,
directors shall be elected at each annual meeting of stockholders, by a
plurality of the votes present in person or represented by proxy at the meeting
and entitled to vote at the election of directors.  Each director shall hold
office until his successor shall have been elected and qualified or until his
earlier death, resignation or removal.  Directors need not be residents of
Delaware or stockholders of the corporation.  Any reduction in the authorized
number of directors shall not have the effect of shortening the term of any
incumbent director unless such director is also removed from office in
accordance with Section 3.04.

      Section 3.03  Resignation.  Any director may resign at any time by giving
                    -----------                                                
written notice to the corporation.  A director's resignation shall take effect
at the time specified therein; and unless otherwise specified therein, the
acceptance of such resignation shall not be necessary to make it effective.

      Section 3.04  Removal.  Any director or the entire board of directors may
                    -------                                                    
be removed, with or without cause, by the holders of a majority of the shares
then entitled to vote at an election of directors; except that if the holders of
shares of any class or series are entitled to elect one or more directors by the
provisions of the certificate of incorporation, the provisions of this Section
shall apply, with respect to the removal without cause of a director or
directors so elected, to the vote of the holders of the outstanding shares of
that class or series and not to the vote of the outstanding shares as a whole.

     Section 3.05   Vacancies.  Except as set forth below or unless otherwise
                    ---------                                                
     provided in the certificate of incorporation, any vacancy or any newly
     created directorship resulting from any increase in the authorized number
     of directors may be filled by a majority of directors then in office,
     although less than a quorum, or by a sole remaining director, or by the
     stockholders if there are no directors remaining, and a director so chosen
     shall hold office until the next annual election and until his successor is
     duly elected and qualified. When one or more directors shall resign from
     the board, effective at a future date, a majority of the directors then in
     office, including those who have so resigned, shall have the power to fill
     such vacancy or vacancies, the vote thereon to take effect when such
     resignation or resignations shall become effective, and each director so
     chosen shall hold office as provided in this Section for the filling of
     other vacancies. Notwithstanding anything to the contrary contained in this
     Section, in the event that the vacant office was held by a director
     designated by the holders of the Series B Preferred Stock (the "Series B
     Director") and such vacancy occurs during the period in which at least 25%
     of the originally issued Series B Preferred Stock remains outstanding, the
     vacancy shall be filled by an election : (a) if one or more of the
     remaining directors is a Series B Director, only the Series B Directors are
     entitled to vote to fill the vacancy if it is filled by directors, and they
     may do so by the affirmative vote of a majority of the Series B Directors;
     and (b) only the holders of shares of that voting group are entitled to
     vote to fill the vacancy if it is filled by the stockholders. Any election
     necessary to fill any vacancy of a Series B Director shall be held as soon
     as practicable after the occurrence of any such vacancy, but in any event
     within 20 business days after the occurrence thereof. Except in an
     emergency situation as may be determined in good faith by the unanimous
     written consent of all remaining directors, no action shall be taken by the
     board of directors after the occurrence of any vacancy due to the death,
     disability, resignation, retirement or removal of any director designated
     by Catterton-Simon Partners III, L.P. (other than any action as may be
     necessary to fill such vacancy) until such vacancy is filled in accordance
     with the foregoing provisions of this Section.

      Section 3.06  Regular Meetings.  A regular meeting of the board of
                    ----------------                                    
directors shall be held immediately after and at the same place as the annual
meeting of stockholders, or as soon thereafter as conveniently may be, at the
time and place, either within or without Delaware, determined by the board, for
the purpose of electing officers and for the transaction of such other business
as may come before the meeting.  Failure to hold such a meeting, however, shall
not invalidate any action taken by any officer then or thereafter in office.
The board of directors may provide by resolution the time and place, either
within or outside Delaware, for the holding of additional regular meetings
without other notice than such resolution.

      Section 3.07  Special Meetings.  Special meetings of the board of
                    ----------------                                   
directors may be called by or at the request of the chief operating officer or
any director.  The person authorized to call special meetings of the board of
directors may fix any convenient place, either within or outside Delaware, as
the place for holding any special meeting of the board of directors called by
him.

      Section 3.08  Meetings by Telephone.  Unless otherwise restricted by the
                    ---------------------                                     
certificate of incorporation, members of the board of directors or any committee
thereof may participate in a meeting of such board or committee by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and such participation
in a meeting in such manner shall constitute presence in person at the meeting.

      Section 3.09  Notice of Meetings.  Notice of each meeting of the board of
                    ------------------                                         
directors (except those regular meetings for which notice is not required)
stating the place, day and hour of the meeting shall be given to each director
at least five days prior thereto by the mailing of written notice by first class
mail, or at least three days prior thereto by personal delivery (including
delivery by courier) of written notice or by telephone, telegram, facsimile or
other similar form of communication, except that in the case of a meeting to be
held pursuant to Section 3.08 notice may be given by personal delivery or by
facsimile, telegram or telephone 24 hours prior thereto.  The method of notice
need not be the same to each director.  If mailed, such notice shall be deemed
to be given when deposited in the United States mail, with postage thereon
prepaid, addressed to the director at his business or residence address.  If
sent by telegram, facsimile or similar form of communication, such notice shall
be deemed to be given when sent by such method to the director during normal
business hours at the location of the recipient at the last address or facsimile
number of the director furnished by him to the corporation for such purpose.  If
communicated by telephone, such notice shall be deemed to be given when
communicated directly to the director or to the person designated by the
director as a

                                      -6-
<PAGE>
 
person authorized to receive such notice. Neither the business to be transacted
at nor the purpose of any meeting of the board of directors need be specified in
the notice or waiver of notice of such meeting.

      Section 3.10  Quorum and Manner of Acting.  Except as otherwise may be
                    ---------------------------                             
required by law, the certificate of incorporation or these bylaws, a majority of
the number of directors fixed in accordance with these bylaws, present in
person, shall constitute a quorum for the transaction of business at any meeting
of the board of directors, and the vote of a majority of the directors present
at a meeting at which a quorum is present shall be the act of the board of
directors.  If less than a quorum is present at a meeting, the directors present
may adjourn the meeting from time to time without further notice other than
announcement at the meeting, until a quorum shall be present.  No director may
vote or act by proxy or power of attorney at any meeting of the board of
directors.

      Section 3.11  Interested Directors.  No contract or transaction between
                    --------------------                                     
the corporation and one or more of its directors or officers, or between a
corporation and any other corporation, partnership, association, or other
organization in which one or more of its directors or officers are directors or
officers or have a financial interest, shall be void or voidable solely for this
reason, or solely because the director or officer is present at or participates
in the meeting of the board or committee which authorizes the contract or
transaction, or solely because his or their votes are counted for such purpose,
if the material facts as to his relationship or interest and as to the contract
or transaction are disclosed or are known to the board of directors or the
committee, and the board or committee in good faith authorizes the contract or
transaction by the affirmative votes of a majority of the disinterested
directors, even though the disinterested directors be less than a quorum; the
material facts as to his relationship or interest and as to the contract or
transaction are disclosed or are known to the shareholders entitled to vote

      Section 3.12  Action Without a Meeting.  Unless otherwise restricted by
                    ------------------------                                 
the certificate of incorporation, any action required or permitted to be taken
at any meeting of the board of directors or any committee thereof may be taken
without a meeting, without prior notice and without a vote, if all members of
the board or committee consent thereto in writing and the writing or writings
are filed with the minutes of the proceedings of the board or committee.

      Section 3.13  Executive and Other Committees.  The board of directors, by
                    ------------------------------

committees, each committee to consist of one or more of the directors of the
corporation.  The board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any

place of any such absent or disqualified member. Any such committee, to the
extent provided in the resolution of the board of directors, shall have and may
exercise all the powers and authority of the board of directors in the
management of the business and affairs of the corporation, and may authorize the
seal of the corporation to be affixed to all papers which may require it; but no

dissolution of the corporation or a revocation of a dissolution; (e) amending
the bylaws of the corporation; and (f) unless the resolution of the board
expressly so provides, declaring a dividend, authorizing the issuance of stock
or adopting a certificate of ownership and merger. The delegation of authority
to any committee shall not operate to relieve the board of directors or any
member of the board form any responsibility imposed by law. Subject to the
foregoing, the board of directors may provide such powers, limitations and
procedures for such committees as the board deems advisable. To the extent the
board of directors does not establish other procedures, each committee shall be
governed by the procedures set forth in Sections 3.06 (except as they relate to
an annual meeting), 3.07 through 3.11 and 7.01 and 7.02 as if the committee were

meetings, which shall be reported to the board of directors when required and

fix the compensation of directors. The directors may be paid their expenses, if
any, of attendance at each meeting of the board of directors and each meeting of
any committee of the board of which he is a member and may be paid a fixed sum
for attendance at each such meeting or a stated salary or both a fixed sum and a
stated salary.  No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor.

their services as may be authorized or ratified by the board of directors and no
officer shall be prevented from receiving compensation by reason of the fact
that he is also a director of the corporation. Election or appointment as an
officer shall not of itself create a contract or other right to compensation for
services performed by such officer.

      Section 4.04  Resignation.  Any officer may resign at any time, subject to

board of directors, or, in the case of assistant and other subordinate officers,
by the chief operating officer (whether or not such officer was appointed by the
chief operating officer), whenever in its or his judgment, as the case may be,
the best interests of the corporation will be served thereby, but such removal
shall be without prejudice to the contract rights, if any, of the person so
removed. Election or appointment of an officer shall not in itself create
contract rights.

      Section 4.06  Vacancies.  A vacancy occurring in any office by death,
                    ---------

      Section 5.01  Issuance of Shares  The issuance or sale by the corporation
                    ------------------                                         
of any shares of its authorized capital stock of any class, including treasury
shares, shall be made only upon authorization by the board of directors, except
as otherwise may be provided by law.  Every issuance of shares shall be recorded
on the books of the corporation maintained for such purpose by or on behalf of
the corporation.

      Section 5.02  Stock Certificates; Uncertificated Shares.  The shares of
                    -----------------------------------------                
stock of the corporation shall be represented by certificates, except that the
board of directors may, in accordance with applicable provisions of law,
authorize the issuance of some or all of any or all classes or series of stock
of the corporation without certificates.  If shares are represented by
certificates (or if a holder of uncertificated shares requests his shares to be
represented by a certificate), each certificate shall be signed by or in the
name of the corporation by the chairman or a vice-chairman of the board of
directors, or the chief operating officer or a vice-president, and by the
treasurer or an assistant treasurer, or the secretary or an assistant secretary
of the corporation, representing the number of shares owned by him in the
corporation.  Any of or all the signatures on the certificate may be facsimile.
In case any officer, transfer agent or registrar who has signed or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the corporation with the same effect as if he were such
officer, transfer agent or registrar at the

      Section 5.03  Payment for Shares.  Shares shall be issued for such
                    ------------------                                  
consideration (but not less than the par value thereof) as shall be determined
from time to time by the board of directors.  Treasury shares shall be disposed
of for such consideration as may be determined from time to time by the board.
Such consideration shall be paid in such form and in such manner as the
directors shall determine.  In the absence of actual fraud in the transaction,
the judgment of the directors as to the value of such consideration shall be
conclusive.  The capital stock issued by the corporation shall be deemed to be
fully paid and non-assessable stock if:  (a) the entire amount of the
consideration has been received by the corporation in the form of cash, services
rendered, personal property, real property, leases of real property or a
combination thereof; or (b) not less than the amount of the consideration
determined to be capital pursuant to statute has been received by the
corporation in such form and the corporation has received a binding obligation
of the subscriber or purchaser to pay the balance of the subscription or
purchase price; provided, however, nothing contained herein shall prevent the
board of directors from issuing partly paid shares pursuant to statute.  The
directors may, from time to time, demand payment in respect of each share of
stock not fully paid in the manner prescribed by statute.  In addition, when the
whole of the consideration payable for shares of a corporation has not been paid
in, and the assets shall be insufficient to satisfy the claims of its creditors,
each holder of or subscriber for such shares shall be bound to pay on each share
held or subscribed for by him the sum necessary to complete the amount of the
unpaid balance of the consideration for which such shares were issued or are to
be issued by the corporation.  No person becoming an assignee or transferee of
shares or of a subscription for shares in good faith and without knowledge or
notice that the full consideration therefor has not been paid shall be
personally liable for any unpaid portion of such consideration, but the
transferor shall remain liable therefor, and no person holding shares in any
corporation as collateral security shall be personally liable as a stockholder
but the person pledging such shares shall be considered the holder thereof and
shall be so liable. No executor, administrator, guardian, trustee or other
fiduciary shall be personally liable as a stockholder, but the estate or funds
held by such executor, administrator, guardian, trustee or other fiduciary in
such fiduciary capacity shall be liable.

      Section 5.04  Lost Certificates.  In case of the alleged loss, destruction
                    -----------------                                           
or mutilation of a certificate of stock the board of directors may direct the
issuance of a new certificate in lieu thereof upon such terms and conditions in
conformity with law as it may prescribe.  The board of directors may in its
discretion require a bond in such form and amount and with such surety as it may
determine before issuing a new certificate.

      Section 5.05  Transfer of Shares.  Upon presentation and surrender to the
                    ------------------                                         
corporation or to a transfer agent of the corporation of a certificate of stock
duly endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, payment of all transfer taxes, if any, and the
satisfaction of any other requirements of law, including inquiry into and
discharge of any adverse claims of which the corporation has notice, the
corporation or the transfer agent shall issue a new certificate to the person
entitled thereto, cancel the old certificate and record the transaction on the
books maintained for such purpose by or on behalf of the corporation.  No

                                     -12-
<PAGE>
 
transfer of shares shall be effective until it has been entered on such books.
The corporation or a transfer agent of the corporation may require a signature
guaranty or other reasonable evidence that any signature is genuine and
effective before making any transfer.  Transfers of uncertificated shares shall
be made in accordance with applicable provisions of law.

      Section 5.06  Registered Holders.  The corporation shall be entitled to
                    ------------------                                       
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books as the owner of
shares, and shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise provided by
the laws of Delaware.

      Section 5.07  Transfer Agents, Registrars and Paying Agents.  The board of
                    ---------------------------------------------               
directors may at its discretion appoint one or more transfer agents, registrars
and agents for making payment upon any class of stock, bond, debenture or other
security of the corporation.  Such agents and registrars may be located either
within or outside Delaware.  They shall have such rights and duties and shall be
entitled to such compensation as may be agreed.



                                   ARTICLE VI

                                 Indemnification

      Section 6.01  Definitions.  For purposes of this Article, the following
                    -----------                                              
terms shall have the meanings set forth below:

          (a)       The Corporation. The term "the corporation" means the
                    ---------------
corporation and shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under this Article with respect to the
resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.

          (b)       Other Enterprises. The term "other enterprises" shall
                    -----------------
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to any employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and the

                                     -13-
<PAGE>
 
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the corporation" as referred to in
this Article.

      Section 6.02  Right to Indemnification.  The corporation may indemnify any
                    ------------------------                                    
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.  The corporation may
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnify for such expenses
which the Court of Chancery or such other court shall deem proper.  Any
indemnification under this section (unless ordered by a court) shall be made by
the corporation only as authorized in the specific case upon a determination
that indemnification of the director, officer, employee or agent is proper in
the circumstances because he has met the applicable standard of conduct set
forth in this section.  Such determination shall be made (1) by a majority vote
of the directors who are not parties to such action, suit or proceeding, even
though less than a quorum, or (2) if there are no such directors, or if such
directors so direct, by independent legal counsel in a written opinion, or (3)
by the stockholders.

      Section 6.03  Successful on the Merits.  To the extent that a director,
                    ------------------------

                    ----

for the purposes of verifying compliance with the provisions of this Agreement.
In the event that any such audit indicates that Colorado Greenhouse underpaid
any amount due to BGP under this Agreement, Colorado Greenhouse shall pay such
additional sum and such audit shall be deemed to be binding and conclusive,
unless a request is made, within fifteen days after receipt of a copy of such
audit by Colorado Greenhouse, for a consultation with such auditors.  Such
audit, after consultation and modification, if any, shall be binding and
conclusive unless the consultation results in irreconcilable differences with
respect to any material item in the report.  In such event, the disputed item
will be submitted to a firm of independent certified public accountants,
acceptable to BGP, for resolution, and the fees of such firm shall be paid
equally by Colorado Greenhouse and BGP, unless Colorado Greenhouse is obligated
for full payment pursuant to this Article 6.  If the submission to the
independent certified public accountants results in changes in the audit report,
the report as so changed shall be binding and conclusive.  In the event that the
audit indicates that there were deficiencies in the aggregate amount of $10,000
or more in the amounts which should have been paid by Colorado Greenhouse to BGP

type affecting other persons generally), BGP may elect to terminate this
Agreement upon five days' prior written notice to Colorado Greenhouse; it being
understood and agreed that if such Uncontrollable Forces apply to, relate to or
affect all persons as a general matter, then BGP will not terminate this
Agreement pursuant to the provisions of this Section 15.8, unless such

operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder preclude any other or further exercise
thereof or the exercise of any other right, power or privilege.  The rights and
remedies herein provided are cumulative and not exclusive of any rights or
remedies at law.

         15.10 Severability.  If any term or provision of this Agreement or the
               ------------

be amended at any time by mutual agreement of the Parties hereto and shall be
amended to reflect any change in size of any Other Greenhouse.  If any of the
Other Greenhouses decreases in size or is increased in size by the addition of
space of like quality to its existing space then the Allocated Percentage shall
be adjusted in proportion to the ratio that the change in size bears to the
total size of the Greenhouse and the Other Greenhouses.

the definition of Reserve Amount in the O&M Agreement, and (iii) an increase in
the primary fee to be paid to Brush Greenhouse Partners II LLC, the lessee of

facilities.

          C.   Tenant has entered into a Greenhouse Management Agreement (the

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 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 7(i) (below) and that the growing of
such crops will require the Greenhouse to be heated in a manner requiring the
useful application of thermal energy from the Power Plant into quantities
sufficient to maintain the Power Plant's status as a "qualifying cogeneration
facility" under the Federal Public Utility Regulatory Policies Act of 1978 and
the regulations promulgated thereunder by FERC (collectively "PURPA").
Notwithstanding the foregoing, in the event that Landlord determines that
Tenant's growing of any crops, including tomatoes in any way would fail to
require the Greenhouse to be heated in a manner requiring the useful application
of thermal energy from the Power Plant in quantities sufficient to maintain the
Power Plant's status as a qualifying cogeneration facility under PURPA, Tenant
shall immediately cease growing such crops and shall commence growing such crop
or crops as may be necessary for the Project to be a qualifying facility under
PURPA.

          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 of $850,000 per year, payable in
equal monthly installments of $70,833.33 each, which installments   

                                      -4-
<PAGE>
 
shall commence on the Commencement Date, and shall be due and payable in advance
on the first day of each and every month thereafter during the entire Term of
this Lease, except to the extent Tenant elects to defer up to the first four
monthly installments of rent as provided in paragraph 6b. below. Tenant shall
not be obligated for any rent hereunder with respect to its occupancy and use of
the greenhouse facility prior to the Commencement Date.

               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 the event that Tenant elects to
defer any monthly installments of rent hereunder, Tenant shall provide Landlord
with a notice of its intention to defer payment of such monthly installment of
rent prior to the first due date of such rental payment.  Tenant may exercise
such option only if Tenant is unable to pay the rent provided hereunder out of
cash flow to Tenant from its operation of the greenhouse facility.  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 per annum
above the rate of interest publicly announced or published from time to time by
Bank of America NT and SA as its "reference rate" (such reference rate being
referred to herein as the "Prime Rate") or (ii) ten percent per annum) shall be
payable in equal monthly installments commencing on the first day of the month
following the Deferral Period.  If the Deferral Period is one or two months, the
Deferred Rental Amount plus interest shall be payable in nine equal monthly
installments.  If the Deferral Period is three or four months, the Deferred
Rental Amount plus interest shall be payable 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 prepayment must be
at least $25,000.

               c.   Payment of Rental.  Tenant shall pay all rental (including
                    -----------------                                         
any Deferred Rental Amount) when due and payable, without any setoff,
counterclaim, abatement, deduction or prior demand therefor whatsoever.  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 a default rate equal to the Prime Rate plus six
percent per annum from the first day due until paid.  Unless otherwise  

                                      -5-
<PAGE>
 
directed in writing by Landlord and consented to by Lender, payment of rent
shall be made to Landlord in immediately available funds at its account
maintained at 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 (1) 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 and (2) paid the entire
Deferred Rental Amount plus all interest thereon.  Such account shall be
maintained in the name of Brush Cogeneration Partners/Brush Greenhouse Partners
II LLC 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 (as such term may be defined in a Deposit and
Disbursement Agreement or similar agreement between Landlord, Lender and Central
Bank Denver, National Association or other bank acting as escrow agent) 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.

               e.   Payment for Additional Heat.  It is the parties' intention
                    ---------------------------                               
that Landlord provide only the amount of thermal energy set forth in paragraph
7a.(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  

                                      -6-
<PAGE>
 
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, to the extent that such amount is 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 provided for 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 energy 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 on behalf of
          Landlord to the Federal Energy Regulatory Commission ("FERC"), Docket
          No. QF 89-7-000. For all purposes of this Agreement, the term
          Application shall include all filings, supplements and requests for
          amendments and recertifications made with respect to the Project
          whether or not under such docket number and whether made by or on
          behalf of Landlord or any other party. 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

                                      -7-
<PAGE>
 
          purposes of this Section 7(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.
          Notwithstanding the foregoing, Landlord shall have no obligation to
          provide thermal energy prior to the Commencement Date. At all times
          when Landlord is providing thermal energy from the Power Plant in an
          amount equal to or greater than 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)   To the extent it may do so under its contractual
          arrangements with the City of Brush, 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 obligation to provide any such service if
          to do so would (a) jeopardize its ability to meet, or

                                      -8-
<PAGE>
 
          be in conflict with, its obligation to supply power pursuant to the
          Power Purchase Agreement or any replacement or successor agreement, or
          to meet its own internal demand, (b) jeopardize the Project's status
          as a qualifying facility under PURPA, (c) subject Landlord to rate or
          other regulation as an electric company or utility, or (d) cause
          Landlord to incur any cost for equipment, services or fuel not
          otherwise required to operate the Power Plant. 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
          harmless Landlord 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 its primary
          provider of electrical service for such amount of electrical power;
          and

                    (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 on the contents and operations of the greenhouse.

          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 any 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

                                      -9-
<PAGE>
 
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.
               ------------------------------------ 

               a.   Except as provided in Section 7 above, Tenant shall be
responsible for all costs of operating and maintaining the Premises and (i) all
equipment and facilities used in connection with the Premises, (ii) the
emergency boilers, (iii) the fertilizer and irrigation system, (iv) all other
equipment under the control of Tenant relating to the operation of the Premises
and located in the Auxiliary Building, (v) all piping used exclusively for the
discharge of heat from the thermal storage system (any piping used jointly for
the charge and discharge of heat from the thermal storage system shall be
maintained by Landlord), (vi) the irrigation water storage tank located on the
Project Property and (vii) pumps, piping and similar facilities associated with
any irrigation well serving the Premises and the transporting of water from such
irrigation well to the Premises (collectively, the "Related Facilities") during
the Term and Tenant hereby agrees to operate and maintain the Premises and the
Related Facilities in good condition, 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.
Without limiting the foregoing, Tenant shall conduct its operations so as not to
contaminate or to damage any steam, water or equipment used in the Project's
cogeneration process.  Landlord shall maintain the Auxiliary Building.

               b.   All repairs to the Premises and the Related Facilities or
any installations of equipment or facilities therein are to be made by Tenant at
its expense. Without limiting the generality of the foregoing, Tenant shall keep
all improvements comprising a part of the Premises and the Related Facilities in
good repair and shall promptly replace the same when damaged, together with all
electrical, plumbing

                                      -10-
<PAGE>
 
and other mechanical installations thereon. Tenant will make any and all
replacements from time to time required for the Premises and the Related
Facilities at its expense including, by way of 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, promptly, efficiently,
competently and in a good and workmanlike 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 by 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
plans and specifications to be performed, at its expense, promptly, efficiently,
competently and in a good and workmanlike manner by duly qualified or licensed
persons or entities.  All such work shall comply with all applicable codes,
rules, regulations and ordinances.  Ordinary and customary repairs and
replacements in and on the Premises or to the Related Facilities shall be
promptly undertaken and promptly completed and need not have Landlord's prior
approval, unless such repairs or replacements materially decrease the value or
usefulness of the Premises, the Related Facilities or the Project Property.

                                      -11-
<PAGE>
 
          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 lien 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
planted crops allowed hereunder in place, and under production for a period in
excess of 90 consecutive days in any calendar year or for a total number of days
in any calendar year greater than 120 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 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 days' notice to Tenant, and any claims paid by Landlord on

                                      -12-
<PAGE>
 
behalf of Tenant will become immediately due and owing to Landlord and Landlord
may collect such sums paid together with default interest at the Prime Rate plus
six percent 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 Premises at Tenant's expense.

          13.  Utilities.  Except as set forth in paragraph 7 above with respect
               ---------                                                        
to thermal water from the Power Plant and certain domestic water for use in the
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 and expenses required in connection with the maintenance, repair or
operation of the irrigation system supplying water to the Premises, the
treatment of the water produced by such well or wells and any other cost or
expense of Landlord under the Water Lease Agreement dated as of November 1, 1991
(as amended from time to time), among Landlord, Colorado Power Partners and
Brungardt Farms Company, or such replacement water lease as Landlord may obtain.
Tenant shall also take and use quantities of water pursuant to such lease as may
be necessary to maintain the validity and priority of the permit or decree
associated with such lease.

               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.

          14.  Indemnity and Insurance.
               ----------------------- 

               a.   Indemnity by Tenant.  To the extent permitted by law, Tenant
                    -------------------                                         
shall and does hereby agree to indemnify Landlord and Lender 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 expenses, in connection with
the loss of life, personal injury and/or damage to property and any other claim
arising from and out of the occupancy or use by 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:

                    (i)    public liability insurance including insurance
          against assumed or 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 Premises by or on behalf of Tenant in such amounts as
          Landlord may reasonably request;

                    (iii)  if and to the extent required by law, worker's
          compensation or similar insurance in form and amounts required by law;
          and

                    (iv)   such other insurance as Landlord may require,
          including but not limited to insurance that Landlord is required to
          provide pursuant to the terms of any applicable credit 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
insurance policies evidencing such insurance shall name  

                                      -14-
<PAGE>
 
Landlord or its designee and Lender as additional insured, and shall contain
such other provisions and endorsements as Landlord may request.

               d.   Evidence of Insurance.  Before the date on which such
                    ---------------------                                
insurance first is required to be carried by Tenant, and thereafter, at least 30
days before the effective date of renewal of any such policy, Tenant will
deliver to Landlord either a duplicate original of the aforesaid policy or a
certificate evidencing such insurance.

          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 days' written
notice, to pay Landlord promptly the cost thereof with default interest at the
Prime Rate plus six percent per annum until paid.

          16.  Condemnation.
               ------------ 

               a.   If the whole or any part of the Premises shall be taken
under the power of eminent domain, this Lease shall terminate as to the 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. 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, and 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

                                      -15-
<PAGE>
 
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
               -------------------------------------------------------         
shall not assign, transfer or encumber this Lease in whole or in part or sublet
all or any part of the Premises without first obtaining the consent of Landlord
and Lender, which consent shall be in the sole and absolute discretion of
Landlord and Lender.

          18.  Compliance with Laws and Regulations and Certain Agreements.
               -----------------------------------------------------------  
Tenant, at its sole cost and expense, shall comply with, shall operate and
maintain the Premises and Related Facilities in compliance with and shall cause
the Premises and the Related Facilities to comply with (i) all federal, state,
county, municipal and other governmental statutes, laws, rules, orders,
regulations and ordinances and any permits affecting any part of the Premises or
the Related Facilities, or the use thereof, including, but not limited to, those
which require the making of any structural, unforeseen or extraordinary changes,
whether or not any such statutes, laws, rules, orders, regulations or ordinances
which may be hereafter enacted involve a change of policy on the part of the
governmental body enacting the same, and those relating to disposal of any
hazardous waste generated by the Premises or the Related Facilities and the
obtaining of any permits required for a small quantity waste generator or
otherwise, (ii) all rules, orders and regulations of the National Board of Fire
Underwriters, Landlord's casualty insurer(s) and other applicable insurance
rating organizations or other bodies exercising similar functions in connection
with the prevention of fire or the correction of hazardous conditions which
apply to the Premises or the Related Facilities, and (iii) the terms and
conditions of the Wastewater Agreement (insofar as such agreement regulates and
limits wastewater discharges from the Premises) so as not to jeopardize
Landlord's wastewater disposal rights thereunder (as reasonably determined by
Landlord) and the Grant Agreement (insofar as such agreement requires the hiring
of certain numbers of moderate and low-income workers), both dated August 12,
1991, between the City of Brush and CTI Partners, Landlord's predecessor in
interest.

          19.  Default.

               a.   Event of Default Defined.  Any one or more of the following

          30 days after the giving of notice thereof by Landlord, unless such
          default is of such a nature that it cannot be cured within such 30-day
          period, in which case no event of default shall occur so long as (A)
          Landlord shall determine that the status of the Power Plant as a
          qualifying cogeneration facility under PURPA is not jeopardized by
          such delay, and (B) Tenant shall promptly commence the curing of the
          default within such 30-day period and shall thereafter diligently
          prosecute the curing of same but in no event shall such 30-day period
          be extended for more than a total of 90 days;

expressly provided for below or by applicable law) shall have any one or more of
the following rights in addition to all other rights and remedies provided
elsewhere herein or at law or in equity;

                    (i)    perform, on behalf and at the expense of Tenant, any
          obligation of Tenant under this Lease which Tenant has failed to
          perform and

                                      -18-
<PAGE>
 
          of which Landlord shall have given Tenant notice, the cost of which
          performance by Landlord, together with interest thereon at the default
          rate equal to the Prime Rate plus six percent per annum from the date
          of such expenditures, shall be deemed additional rental and shall be
          payable by Tenant to Landlord upon demand;

                    (ii)   elect to terminate this Lease and the tenancy created
          hereby by giving notice of such election to Tenant, and reenter the
          Premises, by summary proceedings or otherwise, and remove Tenant and
          all other persons and property from the Premises, and store such
          property in a public warehouse or elsewhere at the cost of and for the
          account of Tenant without resort to legal process and without Landlord
          being deemed guilty of trespass or becoming liable for any loss or
          damage occasioned thereby;

                    (iii)  after giving notice to Tenant, elect to terminate
          Tenant's right of possession and immediately repossess the Premises by
          legal proceedings, force or otherwise, without terminating this Lease
          and reenter the Premises, by summary proceedings or otherwise, and
          remove Tenant and all other persons and property from the Premises,
          and store such property in a public warehouse or elsewhere at the cost
          of and for the account of Tenant without resort to legal process and
          without Landlord being deemed guilty of trespass or becoming liable
          for any loss or damage occasioned thereby;

                    (iv)   elect to take over the management and operation of
          the greenhouse facility using the trade fixtures and equipment of
          Tenant which Tenant has used in operation of the greenhouse as if
          owned by Landlord in its own right, and continue the operation of the
          greenhouse in its own right or through some additional party, which
          operation may be done without legal liability or obligation to Tenant.
          If this provision of default is invoked, Landlord shall have the right
          to inspect and copy all of the Tenant's records relating to the
          operation of the greenhouse including, without limitation, all
          customer lists and marketing plans relating to the greenhouse and
          ancillary facilities and the Related Facilities; or

                                      -19-
<PAGE>
 
                    (v)    exercise any other legal or equitable right or remedy
          which it may have.

          Any costs and expenses incurred by Landlord (including, without
limitation, reasonable attorneys' fees) in enforcing any of its rights or
remedies under this Lease shall be deemed to be additional rental and shall be
repaid to Landlord by Tenant upon demand.  If this Lease is terminated pursuant
to this Section 19(b), then, if requested by Landlord or its assigns, Tenant
shall assign to Landlord or its assigns Tenant's rights under the Greenhouse
Management Agreement.

          20.  Damages.  If this Lease is terminated by Landlord pursuant to the
               -------                                                          
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 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 any 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  

                                      -20-
<PAGE>
 
independent real estate appraiser named by Landlord (the cost of which appraiser
shall be borne equally by Landlord and Tenant), in which case such damages shall
be payable to Landlord in one lump sum on demand and shall bear default interest
at the Prime Rate plus six percent per annum until paid.

          21.  Subordination and Attornment.
               ---------------------------- 

               a.   Tenant agrees that its rights under this Lease are and shall
remain subject and subordinate to the operation and effect of any mortgage, deed
of trust or security agreement given by Landlord for the benefit of Lender, and
to any other mortgage, indenture, deed of trust or other encumbrance, together
with any conditions, renewals, extensions, modifications, consolidations or
replacements thereof, now or hereinafter affecting or placed, charged or
enforced against all or any portion of the Premises.  This clause shall be self-
operative and no further instruments or subordination shall be required in order
to effectuate it.  Nevertheless, Tenant shall execute, acknowledge and deliver
to Landlord at any time and from time to time, upon demand of Landlord, such
documents as may be requested by Landlord or such mortgagee or trustee to
confirm or effectuate any subordination hereunder.

               b.   Tenant agrees that if Lender obtains title to the Premises,
or if Lender notifies the Tenant that Landlord is in default thereunder, Tenant
will pay to Lender or Lender's designees all rent subsequently payable
hereunder.  Further, Tenant agrees that in the event Lender obtains title to the
Premises, Tenant will, upon request of any such party, automatically become the
Tenant of and attorn to such successor in interest without changing the terms
and provisions of the Lease.

          22.  Notices.
               ------- 

               Notices and other communications with respect to this Lease shall

               ---------------------------                                   
covenants and agrees that the annual useful thermal output available from the
Power Plant provided by Landlord will be used by Tenant to heat the greenhouse
facility, and that Tenant shall take and consume for useful purposes such
amounts of thermal energy as are required by, and shall otherwise comply with,
the terms of the annual thermal usage and output requirements required under
PURPA to maintain the Power Plant's status as a qualifying cogeneration facility
and to comply with that certain Order Granting Application for Certification as

greenhouse operations contained in the Application, a copy of which has
previously been furnished to Tenant.  In the event the FERC Order is amended or
that operating conditions in the Power Plant require that Tenant change its
thermal energy consumption rates, Tenant agrees to comply with all requests of
Landlord to assure maintenance of the Power Plant's status as a qualifying
cogeneration facility under   

                                      -22-
<PAGE>
 
PURPA whether the requirements for the maintenance of such status are set forth
in such amended FERC Order, any application made by Landlord in connection
therewith, or otherwise, provided that if in order to take and consume for
useful purposes thermal energy in excess of what is practicable using the
greenhouse structure then in place, any enlargement or material alteration to
the greenhouse is necessary, the cost of such enlargement or alteration shall be
borne by Landlord. Landlord shall have the right to monitor Tenant's compliance
with the requirements described herein.

          24.  Miscellaneous.
               ------------- 

               a.   Estoppel Certificates.  At any time and from time to time,
                    ---------------------                                     
within ten days after Landlord or any Lender shall request the same, Tenant will
execute, acknowledge and deliver to Landlord and to such Lender or such other
party as may be designated by Landlord an estoppel certificate and consent to
collateral assignment in the form furnished by Landlord, with respect to the
matters relating to this Lease or the status of performance of obligations of
the parties hereunder as may be reasonably requested by Landlord or such Lender.
If Tenant fails to provide such certificate within ten days after request by
Landlord therefor, Tenant shall be deemed to have approved the contents of any
such certificate submitted to Tenant by Landlord or such Lender and Landlord is
hereby authorized to so certify.

               b.   Inspections and Access by Landlord.  Tenant will permit
                    ----------------------------------                     
Landlord, its agents, employees and contractors and Lender and its
representative to enter all parts of the Premises during Tenant's business hours
to inspect the same and to enable Landlord to enforce or carry out any provision
of this Lease including, without limitation, any access necessary for the making
of any repairs that are Landlord's obligation hereunder.

               c.   Right of Access by Tenant.  Tenant shall have the right to
                    -------------------------                                 
use areas reasonably designated by the Landlord for ingress and egress to the
Premises and for loading and unloading operations directly related to the
Premises.  Tenant shall be responsible for and agrees to immediately repair any
damage to such areas and indemnify and hold harmless the Indemnified Parties
from any damage resulting from Tenant's use of such areas and to hold harmless
the Indemnified Parties from any and all claims of any nature whatsoever arising
out of Tenant's use of such areas.

               d.   Remedies Cumulative.  No reference to any specific right or
                    -------------------                                        
remedy shall preclude Landlord from 

                                      -23-
<PAGE>
 
exercising any other right or from having any other remedy or from maintaining
any action to which it may otherwise be entitled at law or in equity. No failure
by Landlord to insist upon the strict performance of any agreement, term,
covenant or condition hereof, or to exercise any right or remedy consequent upon
a breach thereof, and no acceptance of full or partial rent during the
continuance of any such breach, shall constitute a waiver of any such breach,
agreement, term, covenant or condition. No waiver by Landlord of any breach by
Tenant under this Lease shall affect or alter this Lease in any way whatsoever.

               e.   Successors and Assigns.  This Lease and the covenants and
                    ----------------------
conditions herein contained shall inure to the benefit of and be binding upon
Landlord, its successors and assigns, and shall be binding upon Tenant, its
successors and assigns and shall inure to the benefit of Tenant and only such
assigns of Tenant to whom the assignment of this Lease by Tenant has been
consented to in writing by Landlord and Lender.  Upon the sale or other transfer

     Re:  Greenhouse Operation and Management Agreement dated as of
          December 29, 1994; Rifle Greenhouse

Ladies and Gentlemen:

     Reference is made to the following documents:

     1.   Greenhouse Operation and Management Agreement (the "O&M Agreement")
          dated as of December 29, 1994, between Brush Greenhouse Partners II,
          LLC ("BGP II") and Colorado Greenhouse LLC ("Colorado Greenhouse");
          and

     2.   Amended and Restated Cogeneration and Greenhouse Lease Agreement dated
          June 1, 1992, as amended (the "Greenhouse Lease"), between Brush
          Cogeneration Partners ("BCP"), as Lessor, and BGP II, as Lessee.

     Capitalized terms used but not otherwise defined herein shall have the 
meaning set forth in the O&M Agreement.

     You have informed us that you desire to consolidate the operations of the 
Greenhouse, the BGP Greenhouse and the Ft. Lupton Greenhouse with that certain 
greenhouse (the "Rifle Greenhouse") located in or near Rifle, Colorado and 
operated in connection with the American Atlas cogeneration project, and in that
connection that you be allowed to treat the Rifle Greenhouse as an Other 
Greenhouse for all purposes of the O&M Agreement. We acknowledge that the Rifle 
Greenhouse is that greenhouse referenced in the last three lines of paragraph 
3.3(d) of the O&M Agreement.

     BGP II and BCP hereby consent to the treatment of the Rifle Greenhouse as 
an Other Greenhouse.

     You acknowledge that as of January 1, 1996, the Greenhouse Lease and the 
O&M Agreement will be amended to reflect an increase in the size of the 
Greenhouse and an increase in the amount of rent payable under the Greenhouse 
Lease.

     In connection with such matters, Colorado Greenhouse, BGP II and BCP 
each agree that the Allocation Percentage set forth on Exhibit B to the O&M
Agreement will be modified, as follows: (i) as of January 1, 1996, to reflect
the consolidation of the Rifle Greenhouse with the operations of the Greenhouse
and the Other Greenhouses, from 31.135% to 26.330%, and (ii)

Page 2

after the second complete calendar quarter following the completion of the 
expansion described above, from 26.330% to 30.392%.

     In addition, Colorado Greenhouse, BGP II and BCP each agree that the 
definitions of both the Primary Fee and the Primary Fee Deficiency in the O&M 
Agreement shall be amended as follows: (i) as of January 1, 1996, in connection 
with the consolidation of the Rifle Greenhouse with the operations of the Green 
house and the other Greenhouses, substitute $3,240,000 for $2,740,000, and (ii) 
after the second complete calendar quarter following the completion date of the 
BGP II Greenhouse expansion described above, substitute $3,429,092 for 
$3,240,000.

                              Very truly yours,

     Borrower and Brush Greenhouse Partners II, LLC ("BGP II") desire to enter 
into the consent letter, in the form of Exhibit A attached hereto, in favor of 
Colorado Greenhouse LLC ("Colorado Greenhouse") relating to certain amendments 
to the Greenhouse Operation and Management Agreement (the "O&M Agreement") dated
as of December 29, 1994 between BGP II and Colorado Greenhouse. This consent 
letter will allow Colorado Greenhouse to add as an Other Greenhouse that certain

     In connection with the current expansion of the Greenhouse, Borrower and 
BGP II also desire to (A) consent to (i) a change in the Allocation Percentage 
under the O&M Agreement, (ii) a change in the definition of Reserve Amount under
the O&M Agreement, and (iii) an increase in the primary fee to be paid to BGP 
II, as lessee of the Greenhouse, and (B) amend the Amended and Restated 
Cogeneration and Greenhouse Lease (the "Greenhouse Lease") dated June 1, 1992 
between Borrower and BGP II, by a First Amendment in the form Exhibit B attached
hereto (the "Greenhouse Lease Amendment").

     Section 9.5 of the Loan Agreement provides in part that Borrower will not, 
without the prior written consent of the Agents, agree to any amendment, 
supplement or modification of any Basic Document. Because the contemplated

Section 15.5 of the O&M Agreement, the parties thereto have agreed that no 
change in the terms or provisions of the O&M Agreement shall be made without

letter and the Greenhouse Lease Amendment by Borrower and BGP II.

Party hereto without the prior written consent of the other Party; provided,

or different nature. No failure to exercise and no delay in exercising, on the

                              AMENDMENT NO. 2 TO
                        THERMAL SUPPLY LEASE AGREEMENT


          THIS AMENDMENT NO. 2 TO THERMAL SUPPLY LEASE AGREEMENT (this
"Amendment No. 2"), dated as of February 28, 1995, IS BY AND BETWEEN THERMO
COGENERATION PARTNERSHIP, L.P., a Colorado limited partnership ("Thermo"), and
ROCKY MOUNTAIN PRODUCE LIMITED LIABILITY COMPANY, a Colorado limited liability
company ("Rocky Mountain").


                                   RECITALS:
                                   -------- 


          A.   Thermo and Rocky Mountain have previously entered into that
certain Thermal Supply Lease Agreement effective as of March 22, 1993, as
amended by Amendment No. 1, dated December 29, 1994 (the "Agreement"), pursuant
to the terms of which Thermo leased to Rocky Mountain, and Rocky Mountain leased
from Thermo a commercial greenhouse located in Ft. Lupton, Colorado (the
"Facility").

          B.   By Commencement Date Notice and Agreement also dated December 29,
1994, Thermo and Rocky Mountain have fixed the Term of the Agreement and the
Quarterly Payment Dates for payment of Base Rent under the Lease.

          C.   Pursuant to a certain Memorandum Regarding Adjustment of Rent and
Option Price dated March 25, 1993 (the "Adjustment Memorandum"), Thermo and
Rocky Mountain agreed that promptly after conversion of the construction loan
financing for the Plant and the Facility to term loan financing, Thermo would
make certain determinations with respect to the actual average annual rate of
interest for financing of the Plant and the Facility, and that thereafter,
utilizing such redetermined actual average annual rate and the final Contract
Sum for construction of the Facility, the Quarterly Base Rent payment and the
Purchase Option Price Schedule would be revised in accordance with the formula
provided in said Memorandum.

          D.   Thermo is in the process of converting its construction loan
financing for the Plant and the Facility to term loan financing, and has
sufficient information to permit it to make the interest rate determination
required by the said Memorandum.

          E.   Thermo and Rocky Mountain have agreed upon a rate of interest and
on a final Contract Sum to be utilized in such calculations and desire to
finalize such adjustments in anticipation of Thermo's completion of the
conversion of its construction
<PAGE>
 
loan financing for the Plant and the Facility to term loan financing.

          NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto agree as
follows:


                                   AGREEMENT
                                   ---------


          1.   All capitalized terms used herein but not otherwise defined shall
have the meaning given to such terms in the Agreement.

          2.   Paragraph 4.1 of the Agreement is hereby amended by deleting the
first two sentences in their entirety, and replacing them with the following two
sentences:

               Subject to deferral in the manner provided in paragraph
          4.6, below, and as adjusted in accordance with a certain
          "Memorandum Regarding Adjustment of Rent and Option Price"
          dated March 25, 1993 (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 Nineteen Million Seven Hundred
          Twenty-Eight Thousand Nine Hundred Fifty-Nine and 15/100
          dollars ($19,728,959.15). 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 Fifty-Six Thousand Two Hundred Twenty and 25/100
          dollars ($256,220.25).

          3.   In accordance with the Adjustment Memorandum, the prior Exhibit
"C" to the Agreement, which shows the Base Rent Purchase Price of the Facility
prior to the first Quarterly Payment Date as being $7,800,000, is hereby
deleted, and there is substituted therefor the Exhibit "C" attached hereto,
wherein the Base Purchase Price of the Facility prior to the first Quarterly
Payment Date is Eight Million Seven Hundred Ninety-Four Thousand Four Hundred
Thirty-Five and 18/100 Dollars ($8,794,435.18).

          4.   Nothing herein shall be construed to be in derogation of the
provisions of a certain Supplemental Agreement and Consent to Assignment
effective as of April 7, 1993 (the "Supplemental Agreement") between and among
Thermo, Rocky Mountain, and The Prudential Insurance Company of America
("Prudential") on its own behalf and in the capacities therein stated, wherein,
among other things, Thermo and Rocky Mountain agreed that Rocky Mountain would
not be entitled to exercise the rights conferred under 

                                      -2-
<PAGE>
 
section 5 or be deemed to have exercised such rights under section 12 of the
Agreement under certain circumstances. Thermo and Rocky Mountain hereby
reiterate and reaffirm all terms, conditions, and covenants of the Supplemental
Agreement as if the same were being made simultaneously with this Amendment No.
2, and agree that upon being requested by the Lead Agent or the Bank Agent to do
so they will extend the benefit of the Supplemental Agreement directly to
additional Lenders (i.e. Lenders under the Loan Agreement in addition to
Prudential) and to the Bank Agent, their respective successors and assigns.
Capitalized terms used in this paragraph but not defined in this paragraph or
elsewhere pursuant to this Amendment No. 2 have the meanings given to such terms
in the said Supplemental Agreement.

          5.   Except as amended or modified by this Amendment No. 2 and the
said Amendment No. 1, the Agreement remains in full force and effect and is
hereby ratified and confirmed in all respects.


          IN WITNESS WHEREOF, the parties hereto have executed this Amendment as
of the date first above written.

                                    --------


          A.   Thermo and Rocky Mountain are parties to that certain Thermal

follows:


                                   AGREEMENT
                                   ---------

have the meaning given to such terms in the Agreement.

          2.   Paragraph 4.1 of the Agreement is hereby amended by deleting the

          Installments of Base Rent shall be payable on the last day
          of April, July, October, and January, beginning April 30,
          1995 and continuing on each such day thereafter through and

          final day of such calendar quarter.

          4.   Paragraphs 3 and 4 of this Agreement No. 3 shall remain in effect
only so long as the O&M Agreement is in effect. Thereafter the amended
provisions of paragraphs 4.1 and 4.5 shall revert to read as they existed prior
to this Amendment No. 3.

          5.   With respect to the calculation of Additional Rent attributable
to real property and other property taxes for the calendar year 1994 payable in

Schedule 2.02 - Wastewater Discharge Quantities
Schedule 5.06 -  TCP Monthly Gas Cost Averaging Methodology


                           SERVICES SUPPLY AGREEMENT

     This Service Supply Agreement (this "AGREEMENT") is made and entered into
as of June 10, 1997, by and between COLORADO GREENHOUSE, INC., a Delaware
corporation ("CGI"), and THERMO COGENERATION PARTNERSHIP, L.P., a Colorado
limited partnership ("TCP").


                                   Recitals
                                   --------

     A.   TCP is the owner of certain land (the "THERMO PROPERTY") located in
the City of Ft. Lupton, County of Weld and State of Colorado, and of certain
buildings and improvements located thereon, including a twenty (20) acre
greenhouse (the "EXISTING GREENHOUSE") and a gas-fired cogeneration power plant
(the "POWER PLANT").  TCP leases approximately 35 acres of the Thermo Property
(the "LEASED LAND"), including the Existing Greenhouse to ROCKY MOUNTAIN PRODUCE
LIMITED LIABILITY COMPANY, a Colorado limited liability company ("ROCKY
MOUNTAIN") pursuant to a certain Thermal Supply Lease Agreement bearing an
effective date of March 22, 1993 (as heretofore and hereafter amended and
supplemented from time to time, the "ROCKY MOUNTAIN TSA"), a complete copy of
which has heretofore been furnished by Rocky Mountain to CGI.

     B.   COLORADO GREENHOUSE LLC, a Colorado limited liability company ("CG"),
an affiliate of CGI, operates the Existing Greenhouse pursuant to a certain
Greenhouse Operation and Management Agreement dated as of December 29, 1994
between Rocky Mountain and CG.

     C.   CGI has acquired from Thermo Greeley I, Inc., a Colorado corporation
("THERMO GREELEY"), certain real property (the "CGI PROPERTY") consisting of
approximately 26.752 acres of land adjacent to the Leased Land, as more
particularly described on EXHIBIT A attached hereto. The CGI Property has been
duly subdivided pursuant to that certain Subdivision Plat of the Colorado
Greenhouse Addition which was recorded on May 12, 1997 in the real property
records of the Office of the Clerk and Recorder of Weld County, Colorado, at
Reception No. 02547711.  CGI intends to construct a twenty (20) acre greenhouse
(the "NEW GREENHOUSE") on the CGI Property in close proximity to the Existing
Greenhouse.  CGI and CG intend to jointly market, sell and distribute the
produce from the Existing Greenhouse and the New Greenhouse.
<PAGE>
 
     D.   In connection with the operation of the Power Plant and the Existing
Greenhouse, TCP (as one of multiple successors and assigns of Thermo Carbonic,
Inc.) obtains water and has access to wastewater discharge services from the
City of Ft. Lupton (the "CITY") pursuant to a certain Annexation Agreement dated
as of December 6, 1991 (the "ANNEXATION AGREEMENT") which is recorded in Book
1352 as Reception No. 02305317 in the land records of Weld County, Colorado.  In
addition, TCP generates thermal energy at the Power Plant and obtains natural
gas from third parties.  TCP furnishes thermal energy and natural gas to Rocky
Mountain for use in the Existing Greenhouse pursuant to the Rocky Mountain TSA.

     E.   CGI desires to obtain from TCP and TCP desires to furnish to CGI
thermal energy and certain other services, and the use of certain easements (the
"EASEMENTS") through which such services may be provided,  as described below,
useful for CGI's operation of the New Greenhouse.

     NOW, THEREFORE, in consideration of the above Recitals and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows:


                                   ARTICLE I
                              GENERAL PROVISIONS

     1.01 Construction of New Greenhouse.  CGI has commenced construction of the
          ------------------------------                                        
New Greenhouse and shall use due diligence to complete and commence operations
within the shortest practical time.  CGI shall substantially complete
construction of the New Greenhouse on or before December 1, 1997.  The term "New
Greenhouse" shall include all new or modified facilities necessary or desirable
for TCP to furnish and CGI to receive the Services.  Except as provided in
Section 4.02, below, TCP shall not be required to bear or contribute to the cost
of any such new or modified facilities.

     1.02 Agreement to Provide Services.  TCP shall, during the Term of this
          -----------------------------                                     
Agreement, provide to CGI the services described in Articles II, III, IV, and V,
below (the "SERVICES") upon the terms and conditions and for the consideration
specified herein.  TCP's obligation to provide Services shall commence on the
substantial completion of construction of the New Greenhouse or on such earlier
date as all such facilities required to deliver the Services have been installed
by CGI and CGI has need of the Services.

     1.03 Services Separable.  Each of the Services to be provided by TCP to CGI
          ------------------                                                    
is described separately in Articles II through V of this Agreement.  If for any
reason any one or more of the Services is terminated, then, unless otherwise
agreed in writing by the parties, the provisions of this Agreement shall remain
in full force and effect as to the other Services; provided, however, that TCP
shall have no obligation to furnish any of the other Services to CGI at any time
when CGI has not accepted, and it appears to TCP that CGI will not accept, for
the 

                                      -2-
<PAGE>
 
calendar year in question CGI's maximum annual purchase obligation (as set forth
in section 4.3) for thermal energy for use in the New Greenhouse; provided,
however, that prior to suspending such other Services, TCP shall notify CGI of
TCP's intention to suspend such other Services at a future date not less than
thirty (30) days from the date of such notice; and provided, further that if,
within such period, CGI furnishes adequate assurances to TCP that the annual
purchase obligation will be met, TCP shall not suspend any other Services.

     1.04  Term.  The term ("TERM") of this Agreement shall commence on the date
           ----                                                                 
first above written and shall expire upon the earlier of the following:  (a)
June 4, 2019, (b) the mutual written consent of both parties hereto, or (c) the
date upon which the Annexation Agreement expires or is terminated; provided,
however, that in the event this Agreement is terminated under clause (c) above,
the parties hereto shall amend and restate this Agreement to continue the same
in effect until (a) or (b) occurs in the event that the Annexation Agreement is
renewed or otherwise extended without material change.


                                  ARTICLE II
                              WASTEWATER SERVICES

     2.01  Agreement to Accept Wastewater from New Greenhouse.  Subject to
           --------------------------------------------------             
compliance by CGI with the terms and conditions of this Agreement, the
Annexation Agreement, and a certain "Subdivision Agreement" dated May 13, 1997
between the City and CGI which agreement includes, among other things, a written
acknowledgment that the City will consider the New Greenhouse a part of the
"PROJECT" (as such term is defined in the Annexation Agreement) and the City's
written consent to the furnishing of wastewater services to the New Greenhouse
under this Agreement, TCP shall permit CGI to discharge wastewater from the New
Greenhouse through TCP's existing wastewater discharge system which connects the
Power Plant and Existing Greenhouse to the City's sewer service lines ("JOINTLY
USED LINE").  If any sewerage lines or other facilities are required to be
constructed on TCP's property, TCP's obligation to furnish wastewater services
to the New Greenhouse shall not commence until such time as (i) such facilities
have been constructed at the sole expense of CGI, and (ii) a separate written
easement agreement, in form substantially similar to EXHIBIT B attached hereto,
confirming the location of and CGI's duty to maintain such new facilities shall
have been executed between CGI and TCP.

     2.02  Characteristics and Volumes of Wastewater Discharge.
           --------------------------------------------------- 

           (a) The wastewater generated by the Existing Greenhouse and the New
Greenhouse combined shall not contain substances or chemical components in
volumes or concentrations or exhibit characteristics that exceed allowable
tolerances for characteristics as set forth in Section C.4 of the Annexation
Agreement.  Should the quality or nature of the wastewater from the New
Greenhouse (i) at the point of discharge (the "WASTEWATER DISCHARGE POINT") to
TCP's wastewater discharge lines fail to meet the standards set forth in the
Annexation 

                                      -3-
<PAGE>
 
Agreement for discharge by TCP into the City's sewer system, or (ii) contribute
to the failure of TCP's wastewater discharge to meet the Annexation Agreement
standards at the point it is discharged by TCP into the City's sewer system
(except to the extent such failure would not have occurred but for a material
alteration by TCP of its existing wastewater discharge practices), then CGI, at
its sole cost and expense, shall pretreat such wastewater, or a portion of it,
to the extent necessary to make CGI's wastewater comply with such standards. The
provisions in this Section are in addition to the rights and remedies available
to TCP under Section 9.04.

          (b)  Subject to Section 2.02(c), below, the maximum rate of flow (in
gallons per minute) and volume of wastewater discharged by CGI into TCP's system
by CGI and Rocky Mountain combined shall not exceed the lesser of (i) the
capacity available from time to time of the existing facilities, or (ii) the
limits on SCHEDULE 2.02.  The parties acknowledge that the historic peak
discharge of wastewater from the Existing Greenhouse has been approximately
75,000 gallons per day, however, the requirements of this Agreement shall govern
future combined discharge volumes.  With respect to capacity available from time
to time, CGI's right to discharge wastewater into the TCP system shall be
subject to pre-emption of such capacity by usage of the wastewater system
downstream by the City, and by usage of the Jointly Used Lines by TCP for
wastewater discharge from the Power Plant.

          (c)  In addition, CGI, in combination with Rocky Mountain, shall be
permitted to discharge into TCP's wastewater discharge facilities such
quantities of wastewater in excess of the amounts specified in Schedule 2.02 to
the extent that such additional discharge does not exceed the maximum total
wastewater discharge rights of "ANNEXORS" under the Annexation Agreement
(including without limitation the rights of TCP and Thermo Greeley I, Inc.,
their successors and assigns) less the aggregate portion of such maximum
discharge capacity which is then being used by the City, TCP, and Rocky
Mountain.  Under no circumstances shall CGI be construed to be an assignee of
any rights or privileges of Annexors under the Annexation Agreement.

          (d)  TCP and CGI acknowledge that the capacity of the existing
wastewater disposal facilities is such that when the City is utilizing such
facilities downstream from the Plant, and the Plant is discharging into the
system at its peak capacity, the capacity of the wastewater disposal facilities
may be inadequate to permit discharge by Rocky Mountain and CGI of the volumes
shown on Schedule 2.02.  The parties also acknowledge that the Existing
Greenhouse includes wastewater holding facilities to accommodate these temporary
system overloads.  Should it be determined at any time that such holding
facilities are insufficient to accommodate wastewater generated from the New
Greenhouse and the Existing Greenhouse combined, CGI shall curtail or
discontinue (as required) its use of the existing wastewater discharge
facilities until such time as CGI, at its cost, has increased the capacity of
the discharge or holding facilities.  In the alternative, CGI may make other
lawful arrangements suitable to CGI for the disposal of wastewater from the New
Greenhouse.  TCP's prior written consent (which shall not be withheld or delayed
unreasonably) shall be required for any modification by CGI of TCP's or the
City's wastewater facilities which affect the operation of the Existing

                                      -4-
<PAGE>
 
Greenhouse or Power Plant. It shall be reasonable for TCP to withhold such
consent if TCP's operations would be disrupted or impaired in any material way
by CGI's activities.

     2.03  Sampling and Metering.  If not already existing upstream from where
           ---------------------                                              
the combined Rocky Mountain/CGI wastewater flow enters TCP's system, CGI, at its
sole cost and expense, shall construct and operate wastewater sampling, flow
equalization, and flow recording facilities at the Wastewater Discharge Point to
measure compliance with the wastewater characteristics, discharge flow rates and
discharge volumes from the Existing Greenhouse and the New Greenhouse.  CGI
shall furnish to TCP quarterly reports of such records within thirty (30) days
after the close of each calendar quarter concerning wastewater characteristics,
flow rates, and volumes.  TCP shall have the right to request and receive more
frequent reports at reasonable intervals.  If CGI discovers samples,
measurements, or conditions that violate the terms of the Annexation Agreement,
that exceed the volume limits set forth on Schedule 2.02, or that CGI reasonably
believes may interfere with or otherwise have an adverse effect on TCP's
wastewater discharge under the Annexation Agreement, CGI shall immediately
notify TCP. Further, TCP may, at its sole discretion, and at reasonable times,
elect to audit or review such sampling and measurement practices and may take
such additional samples as TCP deems necessary or advisable to insure compliance
with all wastewater discharge criteria under this Agreement.  Subject to
reasonable notice delivered to CGI, TCP shall have access to the Wastewater
Discharge Point for the purpose of taking any such samples and monitoring any
meter required by this Agreement.

     2.04  Payment.  CGI shall reimburse TCP monthly for TCP's actual cost
           -------                                                        
charged by the City for the volume of wastewater discharged from the New
Greenhouse during that month, and for any and all other costs charged by the
City pertaining to wastewater services provided hereunder to the extent such
costs can reasonably be allocated to the New Greenhouse.  Should the combined
volume of discharge of wastewater by Rocky Mountain and CGI into the TCP
facilities, when aggregated with the volume of wastewater discharged by TCP
(including peak volume discharges from the Plant) cause the City to impose
charges on the Project's discharge at rates in excess of the rates available to
the Annexors for stipulated discharges under the Annexation Agreement, CGI shall
reimburse TCP at such higher rates for such incremental volumes.  If practical
to do so and if permitted by the City in a manner which will assure that TCP
will receive credit for such payments, CGI shall pay directly to the City all
charges allocable to the New Greenhouse.  In the event that TCP receives notice
from the City of a rate adjustment for wastewater discharge service, TCP shall
promptly deliver a copy of said notice to CGI.  Nothing herein shall preclude
TCP from passing on to Rocky Mountain, in such manner as may be determined from
time to time between TCP and Rocky Mountain, any charges reasonably allocable to
the Existing Greenhouse for wastewater discharge, including without limitation
costs for excess usage at higher rates than those provided in the Annexation
Agreement.

                                     WATER

     3.01  Agreement to Provide Water.  Subject to the terms and conditions of
           --------------------------                                         
this Agreement and the Annexation Agreement, and compliance by CGI with the
applicable terms of the Subdivision Agreement, TCP shall provide water from the
City, and treat a portion of such water in TCP's existing treatment facilities,
to CGI for use in the New Greenhouse.  Such water shall be provided through
TCP's existing waterlines to TCP's water treatment facility on the Thermo
Property and through new waterlines to be constructed by CGI at CGI's expense
from TCP's existing waterlines both upstream and downstream from the water
treatment facility.  All costs in connection with the installation of such new
lines and any necessary upgrading of TCP's existing lines shall be borne by CGI.
TCP's obligation to furnish and treat water to CGI shall not commence until such
time as (i) all new and upgraded (if necessary) waterlines have been
constructed, and (ii) a separate written easement agreement, in form
substantially similar to EXHIBIT B attached hereto, confirming the location of
and CGI's duty to maintain such waterlines shall have been executed between CGI
and TCP.  TCP's obligation to furnish such water shall at all times be limited
to the quantities and flow rates provided in paragraph 3.02.  Under no
circumstances shall TCP be required to incur any cost or expense for upgrade or
expansion of TCP's water treatment facilities in order to provide water service
under this Agreement.

     3.02  Water Quality and Quantity.

           (a) The quality of the treated water furnished by TCP to CGI
hereunder shall be comparable to that currently furnished by TCP to Rocky
Mountain for use in the Existing Greenhouse. To the extent TCP provides treated
water to CGI in a manner comparable to the existing standards under which it
provides treated water to Rocky Mountain, TCP shall not be responsible to CGI if
such water quality is or should become unsatisfactory for use in the New
Greenhouse.

           (b) The maximum respective rates of flow per minute and daily volumes
of water which TCP shall be obligated to furnish to the Existing Greenhouse and
the New Greenhouse shall not exceed 200 gallons per minute (gpm) and 288,000
gallons per day (gpd) of treated water, and 200 gpm and 250,000 gpd of untreated
water.  Notwithstanding the foregoing, TCP shall not at any time have any
obligation to furnish to CGI water at flow rates and volumes in excess of the
flow rates and volumes of water made available to TCP by the City less the
combined amount required by TCP for operation of the Power Plant and the amount
furnished by TCP to Rocky Mountain to service the Existing Greenhouse.  The
parties acknowledge that the historic usage of water in the Existing Greenhouse
has been approximately 65,000,000 gallons per year, and that the limits set
forth in this Agreement shall govern future combined usage by CGI and Rocky
Mountain.

           (c) Notwithstanding the limits in Section 3.02(b), above, so long as
water in excess of that provided in the preceding sentence (i) is available to
TCP under the Annexation 

                                      -6-
<PAGE>
 
Agreement, (ii) is deliverable by TCP to CGI without expansion or modification
of TCP's or the City's existing water service and treatment facilities, and
(iii) is not required for use by TCP or Rocky Mountain, TCP shall also furnish
to CGI such quantities and flow rates of treated and untreated water in excess
of those maximums in the preceding paragraph for use in the New Greenhouse as
CGI shall from time to time request. It is the intent of this paragraph 3.02(c)
to allow CGI to obtain additional treated and untreated water from TCP for use
in the New Greenhouse to the full extent such water is available to TCP from the
City, within the capacity of TCP's current water service and treatment
facilities, and not required for use by TCP and Rocky Mountain.

           (d) TCP makes no representations or warranties concerning the
availability, quality, or quantity of water furnished by the City from time to
time pursuant to the Annexation Agreement, nor does TCP make any representation
or warranty that such water as may be furnished by the City will be sufficient
for CGI's operation of the New Greenhouse.

     3.03  Storage and Metering.  CGI acknowledges that TCP does not have
           --------------------                                          
reservoir facilities to store water for the Existing Greenhouse and the New
Greenhouse.  CGI shall, at its expense, construct whatever reservoir or other
water storage facilities on the CGI Property may be needed to store clean water
furnished to the New Greenhouse pursuant this Agreement.  If requested by TCP,
CGI shall, at CGI's expense, install, operate, and maintain metering as may be
required to differentiate water usage between the Existing Greenhouse and the
New Greenhouse. CGI shall read such meter(s) monthly and report the readings to
TCP.  Until such time as meters may be installed pursuant to this paragraph, TCP
shall not be deemed to be in breach of its obligations hereunder for failure to
accurately differentiate water usage between the Existing Greenhouse and the New
Greenhouse, provided TCP uses reasonable efforts to do so.

     3.04  Payment.  CGI shall reimburse TCP monthly for (i) TCP's actual cost
           -------                                                            
charged by the City for the volume of untreated water which TCP delivers to CGI
hereunder, and (ii) TCP's allocated cost for treated water delivered during that
month to the "WATER DELIVERY POINT." Allocated costs for treated water shall be
calculated in the same manner as TCP calculates costs for treated water
furnished to Rocky Mountain for use in the Existing Greenhouse, adjusted from
time to time for cost of water which TCP pays to the City.  Should the combined
volume of treated and untreated water delivered to Rocky Mountain and CGI, when
aggregated with the volume of water used by TCP (including peak volume usage at
the Plant), cause the City to impose charges on the Project's water usage at
rates in excess of the rates available to the Annexors for stipulated quantities
of water under the Annexation Agreement, CGI shall reimburse TCP at such higher
rates for such incremental volumes.  If practical to do so and if permitted by
the City in a manner which will assure that TCP will receive credit for such
payments, CGI shall pay all charges allocable (in TCP's reasonable discretion)
to the New Greenhouse for untreated water directly to the City and shall
reimburse TCP only for the cost of treated water as described above.  CGI shall
also reimburse TCP for any and all other costs charged by the City pertaining to
water service to the extent such costs can reasonably be allocated to the New
Greenhouse.  In the event that TCP receives notice from the City of a rate

                                      -7-
<PAGE>
 
adjustment for water service, TCP shall promptly deliver a copy of said notice
to CGI.  Nothing herein shall preclude TCP from passing on to Rocky Mountain, in
such manner as may be determined from time to time between TCP and Rocky
Mountain, any charges reasonably allocable (in TCP's reasonable discretion) to
the Existing Greenhouse for water furnished to the Existing Greenhouse,
including without limitation costs for excess usage at higher rates than those
provided in the Annexation Agreement.

                                THERMAL ENERGY

     4.01  Agreements with Respect to Thermal Energy.  TCP shall provide to CGI,
           -----------------------------------------                            
and CGI shall purchase, thermal energy for the operation of the New Greenhouse.
Such thermal energy shall be delivered by TCP to an interconnection point on the
low pressure header at the Power Plant, through a hot water or steam supply and
condensate collection system which shall be constructed by CGI as part of the
New Greenhouse.  The parties acknowledge that TCP intends to retain and use one
hundred percent (100%) of the condensate.  As an essential term of this
Agreement, CGI agrees to use and operate the New Greenhouse only as a greenhouse
for commercial production of agricultural products, or for such alternative uses
(which may not be implemented prior to TCP obtaining certification by the
Federal Energy Regulatory Commission ("FERC") that such alternative use
constitutes a "useful thermal output" pursuant to the requirements set forth in
the Regulations implementing  the Public Utility Regulatory Policies Act of
1978, as amended from time to time, as currently established by FERC and set
forth in Sections 292.201 through 292.207 of title 18, Code of Federal
Regulations, and all amendments of such requirements which may become effective
from time to time, and must in any event require consumption of sufficient
useful thermal energy for the Power Plant to remain a "qualifying cogeneration
facility" pursuant to the aforesaid requirements) as may be approved by TCP
prior to any change of use, provided such TCP approval shall not be unreasonably
withheld or delayed.

     4.02  Payments.  CGI shall pay TCP for thermal energy in monthly payments
           --------
at the rate equal to 1.2 times TCP's actual delivered cost for natural gas equal
in BTU value to the number of BTUs of thermal energy delivered to CGI. Should
CGI so request at least thirty (30) days prior to anticipated substantial
completion of the New Greenhouse, simultaneously with TCP's first delivery of
thermal energy to CGI pursuant to this Agreement, TCP shall pay to CGI the sum
of One Hundred Thousand Dollars ($100,000.00) as full compensation for any and
all costs which CGI may incur in connection with entering into this Agreement,
including without limitation installation and upgrade of all facilities required
under this Agreement and/or the Contract of Sale dated May 12, 1997 between
Thermo Greeley I, Inc. and CGI. Should no such request be made, CGI shall
receive, as full compensation aforesaid, a credit of $100,000 against CGI's
first obligations to pay for Thermal energy first arising under this Section
4.02.

                                      -8-

     4.03  Quantity.  Currently, TCP anticipates that it will be able to make
           --------                                                          
available for use within the New Greenhouse up to two hundred billion
(200,000,000,000) BTUs of thermal energy each calendar year. TCP shall use all
commercially reasonable efforts (but not to include modifications of turbine
load or operation not otherwise consistent with prudent power plant operations)
to make available to CGI a combination of thermal energy and/or natural gas
totaling not less than 80,000,000 BTUs per hour for the operation of the New
Greenhouse. TCP shall be obligated to deliver, and CGI shall be obligated to
purchase, CGI's actual requirements for thermal energy used in the New
Greenhouse, but not in excess of one hundred billion (100,000,000,000) BTUs per
calendar year; provided, however, that if TCP is unable to deliver such amount
of BTUs in thermal energy, TCP shall deliver such lesser quantity of BTUs of
thermal energy as TCP shall produce and be able to make available to the New
Greenhouse, together with natural gas of sufficient BTU value to equal one
hundred billion BTUs when combined with the thermal energy delivered, as
requested by CGI.  In the event that CGI's needs for thermal energy exceed the
foregoing maximum obligations of TCP, CGI shall notify TCP of its additional
needs and TCP shall use reasonable efforts to supply such additional amounts
consistent with TCP's normal operation of the Power Plant.  The foregoing
notwithstanding, with respect to calendar year 1997, the one hundred billion
(100,000,000,000) BTU maximum purchase obligation shall be prorated based on the
number of days in the calendar after thermal energy is required by CGI divided
by 360, but CGI shall nevertheless use its best efforts to utilize, and TCP
shall use its best efforts to produce and furnish, additional thermal energy
consistent with TCP's normal operations of the Power Plant and its obligations
to supply thermal energy to the Existing Greenhouse.  If not already constructed
in connection with the Existing Greenhouse, CGI, at its sole cost and expense,
shall construct a metering and instrumentation system, reasonably satisfactory
to TCP, to record the actual amount of thermal energy delivered to by CGI for
the New Greenhouse.  Procedures for measurement of the amount of thermal energy
delivered shall be in accordance with the Rocky Mountain TSA.

                                  NATURAL GAS

     5.01  Existing Supply and Transportation Contracts.  As of the date of this
           --------------------------------------------                         
Agreement, TCP (either directly or through a related company, Thermo Gas
Marketing, Inc.) is purchasing and transporting natural gas to the Existing
Greenhouse and the Power Plant pursuant to various contractual arrangements with
gas producers and transporters.  TCP receives the gas from its third-party
transporters at a meter located on the Thermo Property and transports the gas to
the Existing Greenhouse and the Power Plant through its own pipeline and
facilities.  TCP represents that its existing gas purchase and transportation
arrangements (subject to certain provisions contained therein regarding the
resale of gas) enable it to obtain sufficient quantities of gas in excess of
TCP's requirements for use in the Power Plant to supply to CGI the gas described
in paragraph 5.02, below.  CGI acknowledges that such arrangements include
purchasing natural gas as required in the spot market.

                                      -9-

     5.02  Agreement to Provide Natural Gas.  If TCP is unable to deliver the
           --------------------------------                                  
maximum amount of thermal energy which CGI is required to purchase on an annual
basis under paragraph 4.03, (i.e. one hundred billion (100,000,000,000) BTUs per
year), TCP, upon CGI's request, shall sell and deliver annually to CGI at the
Delivery Point (as hereinafter defined) natural gas with BTU value equal to the
difference between the BTU value of the thermal energy delivered by TCP pursuant
to paragraph 4.03 and CGI's maximum required thermal energy purchase obligation.
TCP shall use all commercially reasonable efforts to make available to CGI a
combination of natural gas and/or thermal energy in a combined amount of not
less than 80,000,000 BTUs per hour for the operation of the New Greenhouse, it
being the intent that CGI's needs for heat for the New Greenhouse should be
satisfied by TCP delivering amounts of thermal energy and natural gas that
together total not less than 80,000,000 BTUs per hour.   Although no monthly
nomination or forecast of gas requirements shall be required from CGI with
respect to such obligatory gas sales, CGI shall use commercially reasonable
efforts to inform TCP of its anticipated gas requirements 24 hours in advance of
its needs.  In addition, provided that CGI furnishes to TCP, not later than ten
(10) days before the month in which such gas is expected to be needed, a non-
binding best efforts estimate of CGI's desired purchases of natural gas from TCP
for the ensuing month, TCP shall use its best efforts to sell and deliver to CGI
at the Delivery Point such additional quantities of gas as CGI shall request
from time to time for use in the New Greenhouse; provided, however, that with
respect to such monthly nominations TCP has first met its requirements for gas
which is required for use in the Power Plant and to furnish thermal energy and
gas to the Existing Greenhouse.  CGI shall indemnify TCP for all storage and
imbalance charges, costs and other expenses incurred by TCP resulting from CGI's
failure to use all of the additional gas requested by CGI as contemplated in the
preceding sentence.   CGI shall have no minimum gas purchase obligation.  TCP's
obligation to use "best efforts" to sell and deliver to CGI such additional
quantities of gas shall not require TCP to construct facilities or contract for
firm, long-term incremental gas supplies requiring payment of demand charges or
transportation service to fulfill such obligations.

     5.03  Delivery Point, Additional Pipeline, and Facilities.  The "DELIVERY
           ---------------------------------------------------                
POINT" shall be one or more locations on TCP's gas distribution system mutually
acceptable to the parties and located on the Thermo Property.  CGI will at its
expense construct and/or maintain such pipeline(s) and install meters and such
other facilities as the parties shall mutually determine are reasonably
necessary to accept and meter the gas at the Delivery Point and transport it to
the New Greenhouse.  CGI acknowledges that because TCP may commingle gas streams
of varying BTU rating (due to ethane content),  the BTU content of gas available
on the low pressure side of TCP's gas header may vary from a low of
approximately 950 BTU per MCF to a high of approximately 1300 BTU per MCF.  If
CGI desires either to limit this variation or to maintain a direct high pressure
connection to a TCP supplier with which CGI intends to arrange direct purchases
under the following Section 5.04, CGI may construct and/or maintain at CGI's
expense a dedicated gas pipeline to the New Greenhouse from the TCP Gas
Facilities (hereinafter defined) upstream from the TCP gas header.  Other than
the range of BTU content of the gas described above, CGI acknowledges that TCP
makes no representation as to the quality of the gas provided hereunder and CGI
accepts such gas "as is."  TCP's obligation to furnish natural gas 

                                      -10-
<PAGE>
 
to CGI shall not commence until such time as a separate written easement
agreement, in form substantially similar to EXHIBIT B attached hereto, setting
forth the location of such metering and pipeline facilities and CGI's
obligations to maintain the same shall be executed between TCP and CGI. In no
event shall TCP have any obligation to construct the meters and facilities
described in this paragraph.

     5.04  Additional Gas.  CGI shall also have the right to arrange for the
           --------------                                                   
purchase of natural gas from third parties and the transportation of the gas to
the point at which TCP receives its gas from third parties (the "RECEIPT
POINT"). The TCP facilities that connect the Receipt Point to the Delivery Point
are herein called the "TCP GAS FACILITIES." To the extent that TCP Gas
Facilities have capacity in excess of that required for transporting gas
required from time to time for use in the Power Plant and for furnishing thermal
energy and gas to the Existing Greenhouse, TCP shall, at no charge to CGI except
for any applicable costs of compression, transport gas delivered at the Receipt
Point for CGI's account through the TCP Gas Facilities to the Delivery Point.
CGI contemplates that any gas purchased by it for delivery under this paragraph
shall meet or exceed general "pipeline quality" standards of Public Service
Company and Colorado Interstate Gas and shall be consistent with the quality of
the gas distributed in TCP's main gas lines. Under no circumstances shall TCP be
required to incur any cost or expense to expand or enhance the TCP Gas
Facilities to accommodate gas purchased by CGI for delivery to TCP and
redelivery to CGI.

     5.05  Pressure. TCP shall provide gas at the low pressure side of TCP's gas
           --------  
headers in excess of 100 psig but in no event greater than 150 psig.

     5.06  Payment.  CGI shall pay TCP monthly for all natural gas supplied by
           -------                                                            
TCP to CGI under this Agreement at the rate equal to TCP's full incremental
monthly costs (as may be adjusted pursuant to Section 5.07 below) of producing,
obtaining, and delivering such gas averaged in accordance with the methodology
illustrated in the SCHEDULE 5.06 attached hereto. Such price is inclusive of all
commodity gathering, transportation, treatment, compression, reservation,
standby and backup charges and taxes, and CGI shall not reimburse TCP for any
additional charges. There shall be no additional charge for the transportation
of gas through the TCP Gas Facilities.

     5.07  Metering
           --------

           (a)  CGI shall install, own, operate, and maintain a meter (or
meters) at the Delivery Point to meter deliveries of gas to CGI. The changing of
charts and calibrating and adjusting of this meter shall be done by CGI, at
CGI's expense. TCP may install, maintain and operate such check measurement
equipment as it may desire but such equipment shall not interfere in any way
with the operation of CGI's measurement equipment.

           (b)  The accuracy of the measuring equipment at the Delivery Point
shall be tested at regular intervals of not less than once each six (6) months.
Notice of the time and 

                                      -11-
<PAGE>
 
nature of each test shall be given by CGI to TCP sufficiently in advance to
permit convenient arrangement for TCP's representative to be present. If, upon
testing of any metering device owned and operated by CGI, such metering device
is found to be inaccurate by two percent (2%) or less, previous readings of such
equipment will be considered correct in computing the deliveries of gas
hereunder but such equipment will immediately be adjusted to record accurately.
If, upon testing, any such measuring equipment is found to be inaccurate by more
than two percent (2%), the meter shall be immediately calibrated to measure
correctly and any previous readings of such equipment will be corrected to zero
error for any period which is known definitely or agreed upon, but in case the
period is not known definitely or agreed upon, such correction will be for a
period covering one-half of the time elapsed since the last test. Further, the
costs of providing natural gas for such period shall be recalculated pursuant to
Section 5.06 above based on volumes adjusted to account for such inaccuracies.
Either party may require a special test of the Delivery Point meter. If any such
test is requested by TCP and, upon such test the measuring equipment is found to
be registering within two percent (2%) of accuracy, the cost of such test will
be charged to TCP; otherwise the cost of all such tests will be borne by CGI. If
for any reason the meter was out of service or out of repair so that the period
of inaccuracy cannot be estimated or computed from the reading thereof, the
amount of gas delivered through the period such meter is out of service or out
of repair will be estimated and agreed upon by the parties hereto upon the basis
of the best data available by using the first of the following methods which is
feasible:

     (i)   by using the registration of any check meter, if installed and
           accurately registering;

     (ii)  by correcting the error, if the percentage of error is ascertainable
           by calibration, test, or mathematical calculation; or

     (iii) by estimating the quantity of gas delivered during the preceding
           periods under similar conditions when the meter was registering
           accurately.

Greenhouse and at all times thereafter throughout the Term of this Agreement,
CGI shall continuously maintain in force and effect the following insurance
coverage:

           (i)  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 New Greenhouse in a minimum aggregate 

                                      -12-
<PAGE>
 
                amount equal to the full insurable value of the New Greenhouse,
                (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. "Full insurable value" means the full
                replacement value of the New Greenhouse, including any
                improvements and equipment without deduction for physical
                depreciation and/or obsolescence; all such policies may have
                deductibles of not greater than $50,000; and

          (ii)  boiler and machinery insurance coverage at the New Greenhouse,
                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, machinery,
                pressure piping, or any other similar objects located on or
                adjacent to the New Greenhouse in a minimum aggregate amount
                equal to the "full insurable value" (as defined above), of the
                New Greenhouse, 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.

Prior to the time that CGI is required to maintain the foregoing insurance
coverage, CGI shall maintain or cause its contractors to 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.

     6.02  Liability Insurance.  Throughout the Term of this Agreement, CGI and
           -------------------                                                 
TCP shall each continuously maintain in force the following insurance coverage:

           (i)  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;

          (ii)  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

          (iii) automobile liability with limits of Two Million Dollars
                ($2,000,000) per occurrence with no aggregate limitation.

     6.03  Certain Policy Requirements.  All insurance policies required under
           ---------------------------                                        
paragraph 6.03 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 TCP), 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 New
Greenhouse.  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.  CGI's policies shall be endorsed to name TCP,
any mortgagee of the New Greenhouse, their respective officers, agents,
partners, and such other parties as may reasonably be requested by TCP as
additional insured parties, as their interests may appear.  TCP's policies shall
be endorsed to name CGI, its managers, agents, and such other parties as may
reasonably be requested by CGI 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 of any work on the New Greenhouse,
and a copy of any renewal policy (or certificate of insurance if then acceptable
to TCP) shall be delivered to TCP and to any mortgagee of the New Greenhouse at
least fifteen (15) days prior to the termination date of any expiring policy.
TCP's liability insurance policy shall provide that in the event of injury as a
result of the sole negligence of TCP, to persons or property on the CGI
Property, TCP'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 CGI and
TCP, the liability coverage of TCP and CGI shall contribute in proportion to the
negligence of the insured parties.  CGI's liability insurance policy shall
provide that in the event of injury, as a result of the sole negligence of CGI
to persons or property on the Thermo Property, CGI'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 TCP and CGI the liability insurance coverage of TCP and
CGI shall contribute in proportion to the negligence of the insured parties.

     6.04  Waiver of Subrogation.  CGI hereby waives, on behalf of itself and on
           ---------------------                                                
behalf of all carriers of the insurance required to be maintained pursuant to
paragraph 6.01, above, all claims, by subrogation or otherwise, which such
waiving party might otherwise have against TCP for loss or damage to the New
Greenhouse, 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.

     6.05  Exculpation for Property Damage.  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 New Greenhouse, shall be kept
in, at or on the CGI Property at CGI's sole risk, or at the risk of those
claiming under CGI.  Without limitation of the foregoing waivers of claims and
subrogation, TCP shall not be liable for any damage to said personal property or
any loss of business by CGI however arising, including without limitation from
the bursting, overflowing, or leaking of water or pipes, from the malfunction of
the heat transfer subsystem, or 

                                      -14-
<PAGE>
 
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 Thermo
Property or from any other cause in any other manner whatsoever, except for the
grossly negligent or willfully tortious acts of TCP.


                                  ARTICLE VII
                                INDEMNIFICATION

     7.01  By CGI.
           ------ 

           (a)  Subject to such waivers and limitations of liability as are
specifically provided hereunder, CGI shall at all times defend, indemnify and
save TCP, TCP's partners, and their respective shareholders, directors,
officers, agents and employees and any lender providing secured financing to TCP
and such lender's shareholders directors, officers, agents and employees
(collectively "INDEMNITEES") harmless from any and all damages relating to the
New Greenhouse, the CGI Property and the Easements, 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 New Greenhouse, or on the CGI
Property or the Easements, resulting in whole or in part from any negligent or
willfully tortious act done or omission by or through CGI, any affiliate of CGI,
or any third party in the New Greenhouse or on the CGI Property or the
Easements, or resulting from CGI's, any such affiliate's or any such third
party's use, non-use, or occupancy of the New Greenhouse in any manner contrary
to the requirements of this Agreement.

           (b)  Without limiting the generality of the foregoing, CGI shall,
except to the extent of such waivers and limitations, defend, indemnify and hold
the Indemnitees free and harmless from and against all liability, loss, cost,
damage 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"
(as defined in the Rocky Mountain TSA and the Supplemental Agreement thereto
dated April 7, 1993 (the "SUPPLEMENTAL AGREEMENT")) or in connection with third-
party claims relating to or in connection with any violation by CGI or its
affiliates, agents, employees, contractors, sublessees, successors or assigns of
any Environmental Law or in connection with any "MATERIALS OF ENVIRONMENTAL
CONCERN" (as defined in the Rocky Mountain TSA and the Supplemental Agreement)
used, generated, treated, stored or otherwise located on the New Greenhouse, CGI
Property or the Easements, or released by CGI or threatened to be released by
CGI in, on, under, from or affecting the Power Plant or the Thermo Property or
the Easements, except to the extent resulting from Indemnitee's negligence or
intentionally tortious acts or omissions.  CGI shall notify the Indemnitees
promptly of any notice, advice or communication from any federal, state,
regional or local governmental entity and instrumentalities thereof or any other
source having jurisdiction  (collectively, "GOVERNMENTAL AUTHORITY") with
respect to Materials of Environmental Concern released by or threatened to be
released by CGI which may be in, on, under, or released from or affecting the
Power Plant or the Thermo Property.  CGI shall also maintain at the New
Greenhouse and the CGI Property, and

keep available for inspection during ordinary business hours and following
reasonable notice by the Indemnitees, accurate and complete records of all
investigations, studies, sampling and testing conducted, and any and all
response actions taken, by CGI or, to its knowledge, by any Governmental
Authority or other person in respect of Materials of Environmental Concern
released by or threatened to be released by CGI which may be in, on, under,
released from or affecting the Power Plant or the Thermo Property or the
Easements.

           (c)  The foregoing covenants 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.

     7.02  By TCP.
           ------ 

           (a)  Subject to such waivers and limitations of liability as are
specifically provided hereunder, TCP shall at all times defend, indemnify and
save CGI and CGI's shareholders, directors, officers, agents and employees
(collectively "INDEMNIFIED PERSONS") harmless from any and all damages relating
to the Power Plant, 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 Power Plant or the Thermo Property exclusive of the Leased Land and
the Easements, resulting in whole or in part from any negligent or willfully
tortious act done or omission by or through TCP, any affiliate of TCP, or any
third party in the Power Plant or on the Thermo Property exclusive of the Leased
Land and the Easements, or resulting from TCP's, any such affiliate's or any
such third party's use, non-use or occupancy of the Power Plant in any manner
contrary to the requirements of this Agreement.

           (b)  Without limiting the generality of the foregoing, TCP shall,
except to the extent of such waivers and limitations, defend, indemnify and hold
the Indemnified Persons free and harmless from and against all liability, loss,
cost, damage 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 TCP or its affiliates, agents, employees,
contractors, sublessees, successors or assigns of any Environmental Law or in
connection with any Materials of Environmental Concern (as defined in the Rocky
Mountain TSA and the Supplemental Agreement) used, generated, treated, stored or
otherwise located in or on the Power Plant or Thermo Property (exclusive of the
Leased Land), or released by TCP or threatened to be released by TCP in, on,
under, from or affecting the CGI Property, except to the extent resulting from
the negligence or intentionally tortious acts or omissions of the Indemnified
Persons.  TCP shall notify the Indemnified Persons promptly of any notice,
advice or communication from any Governmental Authority  with respect to
Materials of Environmental Concern released by or threatened to be released by
TCP which may be in, on, under, or released from or affecting the CGI Property.
TCP shall also maintain at the Power Plant and Thermo Property, and keep
available for inspection during ordinary business hours and following reasonable
notice by the Indemnified 

                                      -16-
<PAGE>
 
Persons, accurate and complete records of all investigations, studies, sampling
and testing conducted, and any and all response actions taken, by TCP or, to its
knowledge, by any Governmental Authority or other person in respect of Materials
of Environmental Concern released by or threatened to be released by TCP which
may be in, on, under, released from or affecting the CGI Property.

           (c)  The foregoing covenants 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.


                                 ARTICLE VIII
                               DEFAULT; REMEDIES

     8.01  Default.  Should TCP or CGI fail to make any payment required to be
           -------                                                            
made to the other under this Agreement within five (5) days after such payment
is due and payable, or should CGI fail to purchase and receive from TCP the
quantities of thermal energy required under Article IV, above, or to
continuously maintain in force and effect the insurance required of it under
Article VI, above, or should either party fail to perform any other covenant or
comply with any other condition required to be performed or complied with by
such party within thirty (30) days after written demand by the other party to
perform or comply, said non-performing party shall be deemed to be in default of
its obligations under this Agreement.

     8.02  Remedies.  In the event such default is not cured within the
           --------                                                    
applicable cure period (if any), the non-defaulting party shall be entitled to
terminate this Agreement upon ten (10) additional days' written notice if the
default has not been cured within such additional period, and in addition (or in
the alternative) pursue any and all remedies available to it at law or in
equity, including without limitation the remedy of specific performance.  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 damages, damages for lost business, lost profits, or opportunities
therefor, or business interruption, any claim or remedy therefor being
specifically waived by each of the parties.

     8.03  Disputes Resolution.
           ------------------- 

     A.    Unless any third party or parties providing financing to TCP 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 

                                      -17-
<PAGE>
 
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.

          (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.

                                      -18-
<PAGE>
 
     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 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 apportioned 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 

                                      -19-
<PAGE>
 
               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 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.


                                  ARTICLE IX
                                 MISCELLANEOUS

     9.01  Maintenance and Repair; Casualty.  Throughout the Term of this
           --------------------------------                              
Agreement, and except as may otherwise be provided under other sections of this
Agreement or in any of the easement agreements referred to herein, TCP and CGI
shall each use their best efforts to keep and maintain in a state of good and
safe condition and repair and in compliance with all applicable laws the lines,
pipes, fixtures, and other facilities located on the Thermo Property (excluding
the Easements and Leased Land) and CGI Property (including the Easements),
respectively, used from time to time in connection with the furnishing of
Services under this Agreement.  In the event of damage by fire or other
casualty, TCP shall repair, as expeditiously as practical, damage to such lines,
pipes, fixtures, and other facilities located on the Thermo Property, and CGI
shall repair, as expeditiously as practical, damage to such lines, pipes,
fixtures, and other facilities located on the CGI Property.  Under no
circumstances shall either 

                                      -20-
<PAGE>
 
party be in default of its obligations to maintain and repair if such party is
prevented from, or delayed in, making such repairs under the terms of any deed
of trust covering its respective property or other related loan documents.
Nothing in this paragraph 9.01 shall be construed to limit any waivers or
exculpation extended to TCP under paragraph 6.02, above. Further, nothing herein
shall be construed to impose upon TCP or any lender of TCP any obligation to
maintain or repair any lines, pipes, fixtures or other facilities in the event
such lender forecloses or is in the process of foreclosing upon the Thermo
Property or any part thereof, or has exercised any of its other remedies so as
to directly or indirectly control the affairs of TCP, provided that if such
                                                      -------- 
lenders subsequently dispose of TCP as a going concern to any successor person
or entity which continues the operation of the Power Plant then such successor
person or entity shall, if this Agreement shall otherwise be in full force and
effect, be bound by the maintenance and repair obligations of this Section 9.01.

     9.02 Regulatory Compliance.  In the event that any governmental agency or
          ---------------------                                               
authority should assert and continue to maintain that performance by TCP of any
of its obligations hereunder is subject to modification or control by such
agency or authority in the exercise of its regulatory jurisdiction, TCP shall
inform CGI promptly and both parties shall cooperate in efforts to obtain a
release from such asserted jurisdiction.  If they are unable to do so within
ninety (90) days after such jurisdiction is first asserted, TCP shall have the
continuing right to terminate immediately such portion of this Agreement as is
asserted to be subject to regulatory jurisdiction.  If TCP terminates for this
reason, it shall cooperate with CGI's efforts to obtain such services from
public utilities or other third parties reasonably acceptable to CGI, and shall
provide reasonable assistance to CGI in such efforts; provided, however, that
while such cooperation and assistance shall not be construed to require the
granting of any easement, right-of-way, or license with respect to the Thermo
Property, or the Power Plant, TCP shall use all reasonable efforts to support
CGI's efforts to obtain any such easement, right-of-way or license.; provided
that TCP shall have no obligation to perform any actions which would subject it
to additional regulatory control or jurisdiction.

     9.03 Force Majeure.  Subject to the provisions of Section 9.01 above, the
          -------------                                                       
obligations of TCP to supply Services hereunder shall be suspended for so long
as TCP is prevented from performing such obligations by an act of God, strike,
fire, flood, explosion, failure to obtain necessary materials or supplies
(including without limitation failure by the City to supply services or
utilities under the Annexation Agreement), equipment failure (provided TCP has
maintained in good faith, consistent and adequate maintenance practices
thereon), or any other similar cause (a "FORCE MAJEURE").  The obligations of
CGI to make payments hereunder with respect to any specific Services shall be
suspended during any period in which such Services are so suspended.  The
foregoing notwithstanding, no occurrence or circumstance shall give rise to a
condition of Force Majeure unless such occurrence or circumstance is not
reasonably within the control of and could not, in the exercise of reasonable
diligence, have been avoided by the affected party.  Each party shall use its
best efforts to cause all conditions of Force Majeure to be alleviated as soon
as is reasonably possible, 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 the manner and 

                                      -21-
<PAGE>
 
at the time which is within the discretion of the party affected thereby.
Further notwithstanding the foregoing, CGI shall at all times use its best
efforts to continue to purchase and receive thermal energy in accordance with
Article IV.

     9.04 Annexation Agreement; Compliance with Laws.  In addition to its other
          ------------------------------------------                           
obligations under this Agreement, CGI shall at all times utilize the water and
wastewater discharge Services in such a manner which will not cause TCP to
violate any terms or conditions of the Annexation Agreement or any applicable
law, permit or rule or regulation of any governmental agency having jurisdiction
over TCP or CGI (each an 'Applicable Law").  In the event CGI's utilization of
the water and wastewater discharge Services causes (or would cause) TCP to
violate any of the terms or conditions of the Annexation Agreement or an
Applicable Law, TCP shall notify CGI, TCP may suspend providing such Services
until such time as the reason for the violation has been alleviated, and CGI
shall indemnify and save TCP harmless from any liabilities and obligations to
the City resulting from such violations.  Under such circumstances, CGI assumes
full responsibility to obtain, at its cost, water and wastewater services
directly from the City or other third parties.

     9.05 Savings Clause.  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.

     9.06 Entire Agreement.  This Agreement, together with all Exhibits attached
          ----------------

indirectly control the affairs of TCP and elects to discontinue the operations
of the Power Plant, such lender shall have the right to terminate the Services
being provided under this Agreement upon 90 days' prior written notice to CGI.
No lender of TCP shall have the right to terminate the Easements under this
Agreement other than upon the occurrence of a default by CGI hereunder or under

                                   ---------

                          EASEMENT DEED AND AGREEMENT
                          ---------------------------

     THIS EASEMENT DEED AND AGREEMENT (this "Agreement") is made this ___ day of
__________, 1997, by and between THERMO COGENERATION PARTNERSHIP, L.P., a
Colorado limited partnership ("Thermo") and COLORADO GREENHOUSE, INC., a
Delaware corporation ("CGI").

                                   RECITALS
                                   --------

     A.   Thermo is the owner of certain land (the "Thermo Property") located in
the City of Ft. Lupton, County of Weld and State of Colorado, as more
particularly described on Exhibit A attached hereto and made part hereof, and
                          ---------                                          
of certain buildings and improvements located thereon, including a gas-fired
cogeneration power plant (the "Power Plant").

     B.   CGI is the owner of certain land (the "CGI Property") consisting of
approximately 26.752 acres of land adjacent to the Thermo Property, as more
particularly described on Exhibit B attached hereto and made part hereof.
                          ---------                                       
CGI intends to construct a 20 acre greenhouse (the "Greenhouse") on the CGI
Property.

     C.   Pursuant to a Services Supply Agreement (the "Services Supply
Agreement") dated June 10, 1997 between Thermo and CGI, Thermo has agreed to
provide certain utility services to CGI for use in connection with the operation
of the Greenhouse and the parties have agreed in the Services Supply Agreement
to execute and deliver this Agreement.

     D.   CGI desires to obtain from Thermo and Thermo desires to grant to CGI
certain easements over, on and through the Thermo Property in order for CGI to
construct, operate and maintain [DESCRIBE IMPROVEMENTS] in connection with such
services, on the terms and conditions set forth herein.  Capitalized terms not
otherwise defined herein shall have the meanings set forth in the Services
Supply Agreement.

                                   AGREEMENT
                                   ---------

     FOR GOOD AND VALUABLE CONSIDERATION, the receipt and sufficiency of which
are hereby acknowledged by both parties, the parties hereby agree as follows:

     1.   Grant of Easement.  Thermo hereby grants, sells, transfers and conveys
          -----------------                                                     
to CGI a nonexclusive easement (the "General Easement") in and to, over and
across, under and through that strip of real property labeled as Easement
Property (the "Easement Property"), as approximately depicted on Exhibit C
                                                                 ---------
attached hereto and made part hereof, located on the Thermo Property, for the
uses set forth in Section 3.

                                      B-1
<PAGE>
 
     2.   Grant of Access Easement.  Thermo hereby grants, sells, transfers and
          ------------------------                                             
conveys to CGI a nonexclusive easement ("Access Easement") across, over and
through the Thermo Property necessary for pedestrian and vehicular access to the
Easement Property and for all purposes necessary in connection with the
construction of [DESCRIBE IMPROVEMENTS] pipelines (the "Improvements") located
within the Easement Property.  The location of such Access Easement shall be
proposed by CGI in writing and depicted on a survey delivered to Thermo, and
subject to approval by Thermo, which approval shall not be unreasonably
withheld.  After Thermo has approved the location of the Access Easement, Thermo
may request that any such Access Easement be relocated by CGI to a location
specified by Thermo in its reasonable determination.  CGI shall not be permitted
to use any Access Easement prior to the determination of the location of such
Access Easement in accordance with the foregoing provisions.  Upon request by
Thermo after construction is complete, CGI shall, at CGI's expense, execute and
record a certificate to such effect in the real property records of Weld County,
Colorado.

     Terms. a. The term of the General Easement shall commence as of the date
     -----                                                                   
hereof and shall continue until the earlier of (i) termination pursuant to
Section 10 below, or (ii) mutual agreement by the parties.

          b.   The term of the Access Easement shall commence as of the date
hereof and shall expire upon completion of the construction of the Improvements.

     3.   Use.  The General Easement and Access Easement  (together, the
          ---                                                           
"Easements") shall be used for the following uses and purposes:

          a.   Improvements.  The General Easement shall be for the
               ------------                                        
construction, reconstruction, replacement, repair, maintenance, operation, and
removal of the Improvements, as CGI from time to time may elect.

          b.   Access.  During construction of the Improvements, CGI shall have
               ------                                                          
the right to access the Easement Property across any Access Easement established
pursuant to Section 2 above.  The Access Easement shall also be for access for
CGI, and its agents, tenants, subtenants, employees, consultants, contractors
and other licensees and invitees along the full length of the Easement Property.

CGI shall indemnify Thermo for any loss, cost, damage or expense suffered or
incurred by Thermo (including any damage or injury to the Power Plant or the
Thermo Property) or any injury to any person or property resulting from CGI's
use of the Easements other than as contemplated hereunder or in violation of
this Agreement.  In the event Thermo reasonably believes that CGI has allowed
any material amounts of Materials of Environmental Concern to be discharged and
transported through the waste water pipeline jointly used by Thermo and CGI (the
"Jointly Used Line") and CGI fails to cease such discharge and transportation
within 48 hours of receiving notice thereof from Thermo, then Thermo shall have
the right to terminate this Agreement insofar as it relates to CGI's rights in
the Jointly Used Line.  For purposes of this 

                                      B-2
<PAGE>
 
Section 4 an amount of Materials of Environmental Concern shall be "material" if
as a consequence of such discharge and transportation either CGI or Thermo could
be (i) obligated for any clean-up, (ii) liable for penalties or fines, (iii) in
danger of losing any permit or license, (iv) in breach of any agreement with the
City of Fort Lupton, or (v) otherwise in violation of any applicable
environmental law.

     4.   Restrictions.  Any and all construction, maintenance, repair,
          ------------                                                 
replacement and reconstruction of the Improvements and related facilities
accomplished or directed by CGI shall be done:  (a) upon reasonable prior notice
to Thermo (provided that no notice shall be required for routine inspections and
           --------                                                             
maintenance and work on the Easement Property which does not involve more
workers or equipment than routine inspections and maintenance) and (b) in a
manner so as to minimize, to the extent reasonably possible, any inconvenience
to the normal operation of the Thermo Property and the improvements thereon.
Once such construction, maintenance, repair, replacement or reconstruction is
completed, CGI shall restore the affected portion of the Easement Property to as
near its original condition as practicable.

     5.   Noninterference.  Subject to the rights of others under any of the
          ---------------                                                   
Permitted Exceptions (as defined below) and the provisions of Section 8 below,
Thermo shall not have, nor grant any other party, the right to use the Thermo
Property in any manner which would interfere with or obstruct the use of the
General Easement or Access Easement as contemplated hereunder.

     6.   Transferability.  The Easements and the rights of CGI to the Easements
          ---------------                                                       
shall be for the benefit of CGI and its successors and assigns, to the extent
such successors and assigns are permitted under the provisions of the Services
Supply Agreement.

     7.   Warranties of Thermo.  Thermo warrants that,  subject only to the
          --------------------                                             
exceptions listed on Exhibit D (the "Permitted Exceptions"), Thermo is the fee
                     ---------                                                
simple owner of the Thermo Property free and clear of all liens and
encumbrances, subject only to the Permitted Exceptions. Thermo covenants to
defend the rights granted hereby, subject only to the Permitted Exceptions.

     8.   Indemnity by CGI.  CGI at all times (i) shall comply fully with all
          ----------------                                                   
laws, rules, regulations, and ordinances of any Governmental Authority having
jurisdiction with respect to the storage, use or release at the Easement
Property and the portion of the Thermo Property covered by the Access Easement
of hazardous or toxic substances, (ii) shall not use, treat, store, transport or
release or threaten to release any Materials of Environmental Concern in, on,

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.

          (b) In the event a default under this Agreement is not cured within

Agreement upon ten (10) 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,

foregoing, in no event shall either party be liable for any consequential
damages, damages for lost business, lost profits, or opportunities therefor, or
business interruption, any claim or remedy therefor being specifically waived by
each of the parties.

          (c) Upon the expiration or earlier termination of the Services Supply
Agreement, this Agreement shall terminate and the parties hereto shall have no
further rights or 

                                      B-4

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.

Liabilities resulted from the material breach by such Indemnified Party of any

investigation, claim or other proceeding against such Indemnified Party in
respect of which indemnity may be sought from the Company or Investor, as the
case may be, under this Section 9, notify the Company or Investor, as the case
may be, in writing of the commencement thereof. The failure of any Indemnified
Party to so notify the Company or Investor of any such action shall not relieve
the such party from any liability which it may have to such Indemnified Party
under this Section 9 except to the extent that such failure to notify results in
a loss of a material defense of such Indemnified Party or in actual prejudice
due to such action. In case any such action, claim or other proceeding shall be
brought against any Indemnified Party and such Indemnified Party shall notify
the Company and the Investor of the commencement thereof, the Company and
Investor, as applicable, shall be entitled to assume the defense thereof at its
own expense, with counsel satisfactory to such Indemnified Party in its
reasonable judgment; provided, however, that any Indemnified Party may, at its
                     --------  -------
own expense, retain separate counsel to participate in such defense.
Notwithstanding the foregoing, in any action, claim or proceeding in which the
Company, or Investor on the one hand and an Indemnified Party on the other hand
is, or is reasonably likely to become, a party, such Indemnified Party shall
have the right to employ separate counsel at the Company's or Investor's expense
and to control its own defense of such action, claim or proceeding if, in the
reasonable opinion of counsel to the Company or Investor, as applicable, a
conflict or potential conflict exists between the Company or Investor, as
applicable, on the one hand, and such Indemnified Party, on the other hand, that
would make such separate representation advisable. Each of the Company and
Investor agree that it will not, without the prior written consent of CGH (such
consent not to be unreasonably withheld), settle, compromise or consent to the
entry of any judgment in any pending or threatened claim, action or proceeding
relating to the matters contemplated hereby (if any Indemnified Party is a party
thereto or has been actually threatened to be made a party thereto) unless such
settlement, compromise or consent includes an unconditional release of CGH and
each other Indemnified Party from all liability arising or that may arise out of
such claim, action or proceeding. The rights accorded to Indemnified Parties
hereunder shall be in addition to any rights that any Indemnified Party may have
at common law, by separate agreement or otherwise.

          (a)  Neither the Company nor any of its Affiliates is in default or
breach under or with respect to any Contractual Obligation to which it is a
party (and to the best knowledge of the Company and such Affiliates no other
party to any such Contractual Obligation is in default or breach thereunder),
except any such default which, individually or together with all such defaults,

Taxpayers' federal, state, and local returns for Taxes by the relevant taxing
authorities have occurred. None of the Taxpayers have been notified that any
taxing authority intends to audit a return for any period. No extension of a

Taxpayers.

                                INDEMNIFICATION
                                ---------------

          9.1.  Indemnification. In addition to all other sums due hereunder or
                --------------- 
provided for in this Agreement and all other remedies that may be otherwise
available, the Company (an "Indemnifying Party") agrees to indemnify and hold
                            ------------------
harmless each Purchaser and its Affiliates and its respective officers,
directors, agents, employees, Affiliates, partners and assigns (each, an
"Indemnified Party") to the fullest extent permitted by law from and against any
 -----------------                 
and all Environmental Expenses and (i) tax liabilities, (ii) losses, costs,
claims, damages, expenses (including reasonable fees, disbursements and other
charges of counsel) and (iii) other liabilities (collectively, "Liabilities")
                                                                -----------
based upon, relating to or arising out of any breach of any representation or
warranty, covenant or agreement of such Indemnifying Party in this Agreement or
any legal, administrative or other actions (including actions brought by any of
the Purchasers or any Indemnifying Party or any equity holders of the Company or
derivative actions brought by any Person claiming through or in the Company's
name), proceedings or investigations (whether formal or informal), or written
threats thereof, based upon, relating to or arising out of (A) the status of the
Purchasers as shareholders of the Company and the existence or exercise of the
rights and powers of the Purchasers (including without limitation, any claim
against any Indemnified Party relating to Environmental Matters), (B) violations
of applicable securities laws by the Company in connection with (i) the offering
of the Series A Preferred Stock and Series B Preferred Stock and (ii) the
Restructuring Transactions, or (C) third party claims that the Series B
Preferred Stock hereunder violate preexisting understandings or arrangements
with the Company; provided, however, that no Indemnifying Party shall be liable
                  --------  -------         
under this Section 9.1 to an Indemnified Party: (a) for any amount paid in
settlement of claims without such Indemnifying Party's consent (which consent
shall not be unreasonably withheld), (b) to the extent that it is finally
judicially determined that such Liabilities resulted from the willful misconduct
or gross negligence of such Indemnified Party, or (c) to the extent that it is
finally judicially determined that such Liabilities resulted from the material
breach by such Indemnified Party of any representation, warranty, covenant or
other agreement of such Indemnified Party contained in this Agreement; provided,
                                                                       --------
further, that if and to the extent that such indemnification is unenforceable 
- -------                                
for any reason, the Indemnifying Party shall make the maximum contribution to
the payment and satisfaction of such indemnified liability which shall be
permissible under applicable laws. In connection with the obligation of the
Indemnifying Party to indemnify for expenses as set forth above, the
Indemnifying Party further agrees to reimburse each Indemnified Party for all
such expenses (including reasonable fees, disbursements and other charges of
counsel) as they are incurred by such Indemnified Party.

          At the option of the Holders of 66 2/3% of the then outstanding shares
of the Series B Preferred Stock and lieu of cash payment, the Company shall
satisfy its indemnification obligation under this Article 9 through the issuance
to the Indemnified Party of shares of Common Stock having an aggregate fair
value equal to the amount of such obligation.  The fair value of any Common
Stock issued pursuant to the preceding sentence shall be determined initially
(the "Initial Determination") by the Board of Directors (and written notice
      ---------------------                                                
thereof provided to the holders within two (2) business days) after giving
effect to any indemnification obligation, such determination to be made in good
faith.  Any such determination may be challenged in good faith by the holders of
a majority of the Series B Preferred Stock, whereupon a representative of such
holders and the Company shall attempt in good faith to resolve such dispute for
a period not to exceed thirty (30) days.  If within such thirty (30) day period,
such parties fail to resolve such dispute, such dispute shall be resolved
promptly (and in no event later than sixty (60) days after any challenge), at
the Company's expense, by an investment banking firm of recognized national
standing selected by the Company and acceptable to such holders of Series B
Preferred Stock. The Initial Determination shall be deemed approved if the
requisite holders have not 

                                      31
<PAGE>
 
notified the Company of any challenge within thirty (30) days after receiving
notice (including a statement in reasonable detail of the bases therefor) of
such determination.

          9.2.  Notification.  Each Indemnified Party under this Article 9
                ------------ 
shall, promptly after the receipt of notice of the commencement of any action,
investigation, claim or other proceeding against such Indemnified Party in
respect of which indemnity may be sought from any Indemnifying Party under this
Article 9, notify the Indemnifying Party in writing of the commencement thereof.
The omission of any Indemnified Party to so notify the Indemnifying Party of any
such action shall not relieve the Indemnifying Party from any liability which it
may have to such Indemnified Party under this Article 9 except to the extent
that such failure to notify results in a loss of a material defense of such
Indemnified Party in actual prejudice due to such action. In case any such
action, claim or other proceeding shall be brought against any Indemnified Party
and such Indemnified Party shall notify the Indemnifying Party of the
commencement thereof, the Indemnifying Party shall be entitled to assume the
defense thereof at its own expense, with counsel satisfactory to such
Indemnified Party in its reasonable judgment; provided, however, that any
                                              --------  -------  
Indemnified Party may, at its own expense, retain separate counsel to
participate in such defense. Notwithstanding the foregoing, in any action, claim
or proceeding in which both the Indemnifying Party, on the one hand, and an
Indemnified Party, on the other hand, is, or is reasonably likely to become, a
party, such Indemnified Party shall have the right to employ separate counsel at
the Indemnifying Party's expense and to control its own defense of such action,
claim or proceeding if, in the reasonable opinion of counsel to such Indemnified
Party, a conflict or potential conflict exists between the Indemnifying Party,
on the one hand, and such Indemnified Party, on the other hand, that would make
such separate representation advisable. The Indemnifying Party agrees that it
will not, without the prior written consent of the Purchasers (such consent not
to be unreasonably withheld), settle, compromise or consent to the entry of any
judgment in any pending or threatened claim, action or proceeding relating to
the matters contemplated hereby (if any Indemnified Party is a party thereto or
has been actually threatened to be made a party thereto) unless such settlement,
compromise or consent includes an unconditional release of the Purchasers and
each other Indemnified Party from all liability arising or that may arise out of
such claim, action or proceeding. The rights accorded to Indemnified Parties
hereunder shall be in addition to any rights that any Indemnified Party may have
at common law, by separate agreement or otherwise.

          9.3.  Registration Rights Agreement.  Notwithstanding anything to the
                ----------------------------- 
contrary in this Article 9, the indemnification and contribution provisions of
the Registration Rights Agreement shall govern any claim made with respect to
registration statements filed pursuant thereto or sales made thereunder.

          10.1. Termination.  This Agreement may be terminated at any time prior
                -----------

Termination Date is extended by mutual written consent of the Purchasers and the
Company provided, that the right to terminate this Agreement under

fulfill any obligation under this Agreement has been the cause of, or results
in, the failure of the Closing to have occurred by such date;

                ------------------------------------------
representations and warranties made herein shall survive the Closing Date of
this Agreement for a period of three (3) years from the date hereof except the
representations and warranties in (i) Sections 5.11(a), 5.17 and 5.21 shall

things, the documents and agreements listed on Exhibit A attached hereto (the 
"Documents").  We have also examined other agreements and information pertaining
to the Project and have made such investigations of law as we have deemed
relevant and necessary for the purposes of rendering this opinion.

     The opinions, review and analysis set forth below are subject to the 
following further qualifications:

     (a)  This opinion is subject to the effect of bankruptcy, solvency, 
reorganization, moratorium and similar loss generally affecting creditors' 
rights.

     (b)  This opinion does not address matters related to the Occupational 
Safety and Health Act, 29 U.S.C. (S)(S) 651 to 678; the Emergency Planning and

Amendments); or any governmental approvals by or with any governmental authority
pertaining to lending, banking, fiscal or monetary matters.

          2.   Securities Subject to this Agreement.
               ------------------------------------

     ----------------------                                                  
Agreement are the Registrable Securities.

               (a)  Holders of Registrable Securities.  A Person is deemed to be
                    ---------------------------------              
a holder of Registrable Securities whenever such Person owns Registrable
Securities or has the right to acquire such Registrable Securities, whether or

          3.   Demand Registration, Piggy-Back Registration and S-3 
               ----------------------------------------------------
Registration. 
- ------------ 

               (a)  Request for Registration by Holders of Registrable 
                    --------------------------------------------------
Securities.  At any time after the earlier of (i) the last day of the second
- ----------              
Agreement Year or (ii) sixty (60) days after the effective date of any
registration of any of the Company's securities (subject to any hold-back period
agreed upon by the holders of Registrable Securities), if the Company receives
from the holders of at least 30% of the then outstanding Registrable Securities,
a written request specifying that the Company effect any registration or
qualification with respect to the Registrable Securities pursuant to this
Section 3(a) (a "Demand Registration"), the Company will:
                 -------------------                     

                    (1)  within ten (10) days of receipt of such a request, give
written notice of the proposed registration or qualification to all other
holders of Registrable Securities; and

                    (2)  as soon as practicable, use its best efforts to effect
such registration or qualification (including, without limitation, the execution
in the applicable Registration Statement of an undertaking to file required 
post-effective amendments, appropriate qualification under the applicable blue
sky or other state securities laws and appropriate compliance with exemptive
regulations issued under the Securities Act and any other governmental
requirements or regulations) as may be so requested and as are reasonably
necessary to permit or facilitate the sale and distribution of all or such
portion of such holder's or holders' Registrable Securities as are specified in
such request, together with all or such portion of the Registrable Securities of
any other holder or holders joining in such request, or the Company in the case
of securities requested by the Company to be registered (provided, however, the
                                                         --------  -------     
Company shall be permitted to participate in such registration only to the
extent that all Registrable Securities as are specified by any holder in a
Demand Registration request have been included in such registration), as are
specified in a written notice given to the Company within 20 days after the date
of such written notice from the Company pursuant to Section 3(a)(1); provided,
                                                                     --------  
however that the Company will not be obligated to take any action to effect any
- -------     
such registration, qualification or compliance pursuant to this Section 3(a)
after the completion of four (4) Demand Registrations as set forth in Section
3(b).

     Subject to the foregoing provisions, the Company will file a registration
statement covering the Registrable Securities so requested to be registered as
soon as practicable, but in any event within one hundred twenty (120) days,
after receipt of the request or requests of the initiating holders, and shall

                                       3
<PAGE>
 
use its best efforts to cause such Registration Statement and Prospectus through
which such Demand Registration is effected to remain effective until all
Registrable Securities are sold.

     Notwithstanding anything to the contrary set forth in this Agreement, if at
any time any request to register securities pursuant to this Section 3(a) or
Section 3(g), such registration would, in the good faith determination of the
Board of Directors, be substantially detrimental to the Company, then the
Company may direct in writing ("Delay Notice") to the holders of Registrable
                                ------------                                
Securities that such request of registration be delayed for a period of time not
to exceed sixty (60) days from the date of the request, which right to delay may
be exercised not more than once in any one year period.  Upon receipt of a Delay
Notice, the holders of Registrable Securities requesting the Demand Registration
or S-3 Registration (as the case may be) may, upon written notice to the
Company, withdraw such request.

               (b)  Effective Registration.  A registration of Registrable 
                    ----------------------   
Securities will not count as a Demand Registration until it has become effective
and all Registrable Securities included in such Demand Registration have been
sold pursuant thereto. A Demand Registration under Section 3(a) shall be
effected pursuant to a Registration Statement on Form S-3 at any time that the
Company is eligible to use such form for such purpose.

               (c)  Priority on Demand Registrations.  If the holder or holders 
                    --------------------------------   
of a majority in number of the Registrable Securities to be registered in a
Demand Registration under this Section 3 (or the holder or holders who initiated
the Demand Registration) so elect, the offering of such Registrable Securities
pursuant to such Demand Registration shall be in the form of an Underwritten
Offering. In such event, if the managing underwriter or underwriters of such
offering advise the Company and the holders in writing that in their opinion the
Registrable Securities requested to be included in such offering is sufficiently
large so as to materially and adversely affect the success of the offering, the
Company shall include in such registration the maximum amount of Registrable
Securities which in the opinion of such managing underwriter or underwriters can
be sold without any such material adverse effect. The Company shall include
Registrable Securities in such registration as follows: (i) first, pro rata
                                                                   --- ----  
among the holders of Registrable Securities who have requested to be included in
such registration pursuant to Section 3(a); (ii) second, all securities held by
the Company for which the Company has requested inclusion pursuant to Section
3(a); and (iii) third, any other holders of securities of the Company who have
requested to be included in such registration statement.

               (d)  Contemporaneous Demands.  Subject to the proviso in the last
                    -----------------------                          
sentence of Section 3(h) of the Series A Registration Rights Agreement, in the
event that the Company shall receive a request to effect a registration of its
securities pursuant to the Series A Registration Rights Agreement or otherwise
(an "Other Demand Registration"), the Company shall, within five (5) days after 
     -------------------------                                  
receipt of such request, give written notification of such proposed registration
(which notice shall include without limitation the identity of the parties
making such request, the nature and amount of the securities proposed to be
registered and the estimated gross proceeds of such offering) to all holders of
Registrable Securities. If, within thirty (30) days after receipt of such
notice, the holders of Registrable Securities shall deliver to the Company a
request to effect a Demand Registration, then the Company shall effect such
Demand Registration and shall not effect the Other Demand Registration, which
Other Demand Registration shall be withdrawn and shall be of no further force
and effect.

               (e)  Selection of Underwriters.  In the event any such 
                    -------------------------                         
registration is in the form of an Underwritten Offering, the investment banker
or bankers and manager or managers that will administer the offering will be
nationally recognized investment banking firm(s) selected by the 

                                       4
<PAGE>
 
Company with the prior written consent of the holders of a majority in number of
Registrable Securities to be included in such offering, such consent not to be
unreasonably withheld.

               (f)  Piggy-Back Registration.  If the Company determines to file 
                    -----------------------   
a Registration Statement under the Securities Act relating to a proposed sale to
the public of shares of its securities (but excluding registrations relating
solely to employees' stock option or purchase plans or relating solely to a
transaction employing Securities and Exchange Commission Form S-4 or Form S-8 or
successor forms thereto), either for its own account or the account of a
security holder or holders, the Company shall:

                    (1)  promptly give to each holder of Registrable Securities
written notice thereof (which will include, to the extent known at the time, a
list of the jurisdictions in which the Company intends to qualify such
securities under the applicable blue sky or other state securities laws, the
proposed offering price or price range, and the plan of distribution);

                    (2)  include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within forty-five (45) days after such written notice from the
Company, by holders of Registrable Securities; and

                    (3)  use its best efforts to cause the managing underwriter
or underwriters of such proposed Underwritten Offering to permit the Registrable
Securities requested to be included in the registration statement for such
offering to be included on the same terms and conditions as any similar
securities of the Company included therein. Notwithstanding the foregoing, if
the managing underwriter or underwriters of such offering deliver a written
opinion to the Company and the holders of such Registrable Securities that
marketing considerations require a limitation on the number of shares of Common
Stock offered pursuant to any Registration Statement filed under this Section
3(e), such limitation shall be allocated among all holders of Common Stock
(other than such holders, if any, initiating the registration pursuant to demand
registration rights granted by the Company, which holders shall receive priority
with respect to inclusion in such registration in accordance with such
contractual rights) and the holders of Registrable Securities who requested
inclusion in the registration as follows: (i) first, Registrable Securities
shall be included in such registration in a number equal to the greater of (A)
the pro rata portion (in proportion to all shares of Registrable Securities and
    --- ----        
other shares of Common Stock requested to be included in the offering which are
subject to such underwriter's limitation) of Registrable Securities requested to
be included in such registration and (B) seventy-five percent (75%) of the total
number of shares to be included in such registration (other than such holders,
if any, initiating the registration pursuant to demand registration rights
granted by the Company) after giving effect to such underwriter's limitation;
and (ii) second, any other holders of securities of the Company who have
requested to be included in such registration statement pursuant to contractual
piggy-back registration rights.

               (g)  Request for Registration on Form S-3 by Holders of 
                    --------------------------------------------------
Registrable Securities. At any time after the Company becomes eligible to file
- ----------------------  
a Registration Statement on Form S-3, if the Company receives from the holders
of at least 25% of the then outstanding Registrable Securities, a written
request specifying that the Company effect any registration or qualification
with respect to the Registrable Securities pursuant to this Section 3(g) (an "S-
                                                                              -

<PAGE>
 
                    (1)  within ten (10) days of receipt of such a request, give
written notice of the proposed registration or qualification to all other
holders of Registrable Securities; and

                    (2)  as soon as practicable, effect such registration or
qualification (including, without limitation, the execution in the applicable
Registration Statement of an undertaking to file required post-effective
amendments, appropriate qualification under the applicable blue sky or other
state securities laws and appropriate compliance with exemptive regulations
issued under the Securities Act and any other governmental requirements or
regulations) as may be so requested and as are reasonably necessary to permit or
facilitate the sale and distribution of all or such portion of such holder's or
holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other holder or holders
joining in such request, or the Company in the case of securities requested by
the Company to be registered (provided, however, the Company shall be permitted
                              --------  -------                         
to participate in such registration only to the extent that all Registrable
Securities as are specified by any holder in a S-3 Registration request have
been included in such registration), as are specified in a written notice given
to the Company within 20 days after the date of such written notice from the
Company pursuant to Section 3(a)(1); provided, however that the Company will not
                                     --------  -------     
be obligated to take any action to effect any such registration, qualification
or compliance pursuant to this Section 3(g) after the completion of two (2) S-3
Registrations as set forth in Section 3(g).

     Subject to the foregoing provisions, the Company will file a registration
statement covering the Registrable Securities so requested to be registered as
soon as practicable, but in any event within one hundred twenty (120) days,
after receipt of the request or requests of the initiating holders, and shall
use its best efforts to cause such Registration Statement and Prospectus through
which such S-3 Registration is effected to remain effective until all
Registrable Securities are sold.

               (h)  Effective Registration.  A registration of Registrable 
                    ----------------------                                    
Securities will not count as an S-3 Registration until it has become effective
and all Registrable Securities included in such S-3 Registration have been sold
pursuant thereto.

               (i)  Minimum Requirement for Registration.  The Company shall be 
                    ------------------------------------

Section 3(g) only if the anticipated gross offering proceeds pursuant to: (1) a
Demand Registration requested pursuant to Section 3(a) hereof equals or exceeds
$10,000,000 and (2) an S-3 Registration requested pursuant to Section 3(g)
hereof equals or exceeds $1,000,000.

                    (2)  to cause each holder of its privately placed debt or
equity securities issued by the Company at any time on or after the date of this
Agreement (other than securities issued upon the exercise or conversion of
securities outstanding as of the date hereof) to agree not to effect any public
sale or distribution of any such securities, including a sale pursuant to Rule
144 under the Securities Act (except as part of such Underwritten Registration,
if permitted), during the ninety (90) day period subsequent to the filing of the
Registration Statement for each Underwritten Offering and during the 180 day
period following the effective date of such Registration Statement, in each case
to the extent the managing underwriter makes a timely written request that
specifically identifies such holder(s).

          5.   Registration Procedures.
               ----------------------- 

     In connection with the Company's registration obligations pursuant to
Section 3 hereof, the Company will use its best efforts to effect such
registration to permit the sale of such Registrable Securities in accordance
with the intended method or methods of disposition thereof, and pursuant thereto

be made available for review by such holders and managing underwriters, and (i)
with respect to any Demand Registration or S-3 Registration, the Company will
not file any such Registration Statement or amendment thereto or any such
Prospectus or any supplement thereto to which the holders of a majority in
number of the Registrable Securities covered by such Registration Statement or
the underwriters, if any, shall reasonably object; and (ii) with respect to any
Piggy-Back Registration, the Company will not file any such Registration
Statement or amendment thereto or any such Prospectus or any supplement thereto

or the plan of distribution of such holders' Registrable Securities;

               (b)  prepare and file with the Securities and Exchange Commission
such amendments and post-effective amendments to any Registration Statement, and

required by the rules, regulations or instructions applicable to the
registration form utilized by the Company or by the Securities Act or otherwise
necessary to keep such Registration Statement effective for the applicable
period and cause the Prospectus as so supplemented to be filed pursuant to Rule
424

any such Person) confirm such advice in writing,

                    (1)  when the Prospectus or any Prospectus supplement or
post-effective amendment has been filed, and, with respect to the Registration
Statement or any post-effective amendment, when the same has become effective,

                    (2)  of any request by the Securities and Exchange
Commission for amendments or supplements to the Registration Statement or the
Prospectus or for additional information,

                    (3)  of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the initiation of
any proceedings for that purpose,

                    (4)  if at any time the representations and warranties of
the Company contemplated by paragraph (n) below cease to be true and correct,

                    (5)  of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Registrable Securities for
sale in any jurisdiction or the initiation or threatening of any proceeding for
such purpose, and

                    (6)  of the existence of any fact which results in the
Registration Statement, the Prospectus or any document incorporated therein by
reference containing an untrue statement of material fact or omitting to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading;

               (d)  use every reasonable effort to obtain the withdrawal of any
order suspending the effectiveness of the Registration Statement at the earliest

underwriters or a holder of Registrable Securities being sold in connection with
an Underwritten Offering, immediately incorporate in a Prospectus supplement or

and the holders of a majority of the Registrable Securities being sold
reasonably request to have included therein relating to the plan of distribution
with respect to such Registrable Securities, including, without limitation,
information with respect to the amount of Registrable Securities being sold to
such underwriters, the purchase price being paid therefor by such underwriters
and with respect to any other terms of the underwritten (or best efforts
underwritten) offering of the Registrable Securities to be sold in such
offering; and make all required filings of such Prospectus supplement or post-
effective amendment as soon as notified of the matters to be incorporated in
such Prospectus supplement or post-effective amendment;

               (f)  at the request of any selling holder of Registrable
Securities, furnish to such selling holder of Registrable Securities and each
managing underwriter, without charge, such number of conformed copies of the
Registration Statement and any post-effective amendment thereto,

of Registrable Securities and the underwriters, if any, in connection with the
offering and sale of the Registrable Securities covered by the Prospectus or any
amendment or supplement thereto;

               (h)  prior to any public offering of Registrable Securities,
register or qualify or cooperate with the selling holders of Registrable
Securities, the managing underwriters, if any, and their respective counsel in
connection with the registration or qualification of such Registrable Securities
for offer and sale under the securities or blue sky laws of such jurisdictions
as any seller or underwriter reasonably requests in writing and do any and all
other acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by the Registration
Statement; provided that the Company will not be required to qualify generally 
           --------                                         
to do business in any jurisdiction where it is not then so qualified or to take
any action which would subject it to general service of process in any such
jurisdiction where it is not then so subject;

               (i)  cooperate with the selling holders of Registrable Securities
and the managing underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and, if
not required by applicable law, not bearing any restrictive legends; and enable
such Registrable Securities to be in such denominations and registered in such
names as the managing underwriters may request at least two business days prior

               (j)  use its best efforts to cause the Registrable Securities

to enable the seller or sellers thereof or the underwriters, if any, to
consummate the disposition of such Registrable Securities;

               (k)  if any fact contemplated by paragraph (c)(6) above shall
exist during the period that the Company shall be required hereunder to use its
best efforts to maintain the effectiveness of the applicable Registration
Statement, prepare a supplement or post-effective amendment to the Registration
Statement or the related Prospectus or any document incorporated therein by
reference or file any other required document so that, as thereafter delivered
to the purchasers of the Registrable Securities, the Prospectus will not contain
an untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein not
misleading;

               (l)  use its best efforts to cause all Registrable Securities
covered by the Registration Statement to be listed on each securities exchange
on which similar securities issued by the Company are then listed if requested
by the holders of a majority in number of such Registrable Securities or by the
managing underwriters, if any;

               (m)  not later than the effective date of the applicable
Registration Statement, provide a CUSIP number for all Registrable Securities
and provide the applicable trustees or

                                       9

are in a form eligible for deposit with Depository Trust Company;

               (n)  enter into agreements (including underwriting agreements) in
a form reasonably satisfactory to the Company and take all other appropriate and
reasonable actions in order to expedite or facilitate the disposition of such
Registrable Securities and in such connection, whether or not an underwriting

Registration:

                    (1)  make such representations and warranties to the holders
of such Registrable Securities and the underwriters, if any, in form, substance

thereof (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to the managing underwriters, if any, and the counsel to
the holders of Registrable Securities being sold) addressed to each selling

opinions requested in Underwritten Offerings, in a manner reasonably
satisfactory to the Company;

                    (3)  obtain "cold comfort" letters and updates thereof from
the Company's independent certified public accountants addressed to the selling
holders of Registrable Securities and the underwriters, if any, such letters to

Offerings;

                    (4)  if an underwriting agreement is entered into, cause the
same to set forth in full the indemnification provisions and procedures of
Section 7 hereof (or such other substantially similar provisions and procedures
as the underwriters shall reasonably request) with respect to all parties to be
indemnified pursuant to said Section; and

                    (5)  deliver such documents and certificates as may be
reasonably requested by the holders of a majority of the Registrable Securities
being sold and the managing underwriters, if any, to evidence compliance with
paragraph (k) above and with any customary conditions contained in the
underwriting agreement or other agreement entered into by the Company.

     The actions set forth in the above paragraph (n) shall be done at the
effectiveness of such Registration Statement, each closing under any
underwriting or similar agreement as and to the extent required thereunder and
from time to time as may reasonably be requested by any selling holder in
connection with the disposition of Registrable Securities pursuant to such
Registration Statement, all in a manner consistent with customary industry
practice;

               (o)  make available to a representative of the holders of a
majority in number of the Registrable Securities being sold, any managing
underwriter participating in any disposition pursuant to such Registration
Statement, and any attorney or accountant retained by the sellers or managing
underwriter, all financial and other records, pertinent corporate documents and
properties of the Company, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such
representative, underwriter, attorney or accountant in connection with the
registration, with respect to each at such time or times as the Company shall

                                      10
<PAGE>
 
reasonably determine; provided that any records, information or documents that 
                      --------                                 
are designated by the Company in writing as confidential shall be kept
confidential by such Persons unless disclosure of such records, information or
documents is required by court or administrative order;

               (p)  otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and make
generally available to its security holders, earnings statements satisfying the
provisions of Section 11(a) of the Securities Act and Rule 158 promulgated
thereunder;

               (q)  cooperate and assist in any filings required to be made with
the NASD and in the performance of any due diligence investigation by any
underwriter (including any "qualified independent underwriter" that is required
to be retained in accordance with the rules and regulations of the NASD); and

               (r)  promptly prior to the filing of any document which is to be
incorporated by reference into the Registration Statement or the Prospectus
(after initial filing of the Registration Statement) provide copies of such
document to counsel to the selling holders of Registrable Securities and to the
managing underwriters, if any, make the Company's representatives available for
discussion of such document and make such changes in such document prior to the
filing thereof as counsel for such selling holders or underwriters may
reasonably request.

     The Company may require each seller of Registrable Securities as to which
any registration is being effected to furnish to the Company such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing.

     Each holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in paragraph (k) above, such holder
will forthwith discontinue disposition of Registrable Securities until such
holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by paragraph (k) above, or until it is advised in writing by the
Company that the use of the Prospectus may be resumed, and has received copies
of any additional or supplemental filings which are incorporated by reference in
the Prospectus, and, if so directed by the Company, such holder will deliver to
the Company (at the Company's expense, unless such supplement or amendment is
due to inaccurate information supplied by such holder to the Company in writing
specifically for inclusion in the applicable Registration Statement) all copies,
other than permanent file copies then in such holder's possession, of the
Prospectus covering such Registrable Securities current at the time of receipt
of such notice.  In the event the Company shall give any such notice, the time
periods mentioned in Section 4(a) hereof shall be extended by the number of days
during the period from and including the date of the giving of such notice to
and including the date when each seller of Registrable Securities covered by
such Registration Statement either receives the copies of the supplemented or
amended Prospectus contemplated by paragraph (k) above or is advised in writing
by the Company that the use of the Prospectus may be resumed.

          6.   Registration Expenses.

               (a)  Except as set forth in Section 6(c), all expenses incident

                                      12
<PAGE>
 
exists among such selling holders in the exercise of the reasonable judgment of

          7.   Indemnification.
               --------------- 

               (a)  Indemnification by the Company.  The Company agrees to 
                    ------------------------------      
indemnify and hold harmless each holder of Registrable Securities, its officers,
directors, employees and Agents and each Person who controls such holder within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each such person being sometimes hereinafter referred to as an
"Indemnified Holder") from and against all losses, claims, damages, liabilities 
 ------------------                                                
and expenses (including reasonable costs of investigation and legal expenses)
arising out of or based upon any untrue statement or alleged untrue statement of
a material fact contained in any Registration Statement or Prospectus or in any
amendment or supplement thereto or in any preliminary Prospectus, or arising out
of or based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages, liabilities or
expenses arise out of or are based upon any such untrue statement or omission or
allegation thereof based upon information furnished in writing to the Company by
such holder expressly for use therein; provided, however, that the Company shall
                                       --------  -------                        
not be liable in any such case to the extent that any such loss, claim, damage,
liability or expense arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any preliminary
Prospectus if (i) such holder failed to send or deliver a copy of the Prospectus
with or prior to the delivery of written confirmation of the sale of Registrable
Securities and (ii) the Prospectus would have corrected such untrue statement or
omission; and provided, further, that the Company shall not be liable in any
              --------  -------                                    
such case to the extent that any such loss, claim, damage, liability or expense
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission in the Prospectus, if such untrue statement or
alleged untrue statement, omission or alleged omission is corrected in an
amendment or supplement to the Prospectus and if, having previously been
furnished by or on behalf of the Company with copies of the Prospectus as so
amended or supplemented, such holder thereafter fails to deliver such Prospectus
as so amended or supplemented prior to or concurrently with the sale of a
Registrable Security to the person asserting such loss, claim, damage, liability
or expense who purchased such Registrable Security which is the subject thereof
from such holder. This indemnity will be in addition to any liability which the
Company may otherwise have. The Company will also provide customary
indemnification to underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, their
officers and directors and each Person who controls such Persons (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
to the same extent as provided above with respect to the indemnification of the
Indemnified Holders of Registrable Securities.

     If any action or proceeding (including any governmental investigation or
inquiry) shall be brought or asserted against an Indemnified Holder in respect
of which indemnity may be sought from the Company, such Indemnified Holder shall
promptly notify the Company in writing, and the Company shall assume the defense
thereof, including the employment of counsel reasonably satisfactory to such
Indemnified Holder and the payment of all expenses. Such Indemnified Holder
shall have the right to employ separate counsel in any such action and to
participate in the defense 

                                      13
<PAGE>
 
thereof, but the fees and expenses of such counsel shall be the expense of such
Indemnified Holder unless (a) the Company has agreed to pay such fees and
expenses or (b) the Company shall have failed to assume the defense of such
action or proceeding or has failed to employ counsel reasonably satisfactory to
such Indemnified Holder in any such action or proceeding or (c) if the
representation of such Indemnified Holder by the counsel retained by the Company
would be inappropriate due to actual or potential conflicts of interests between
the Indemnified Holder and any other party represented by such counsel in such
proceeding based on written advice of counsel made available to the Company (in
which case, if such Indemnified Holder notifies the Company in writing that it
elects to employ separate counsel at the expense of the Company, the Company
shall not have the right to assume the defense of such action or proceeding on
behalf of such Indemnified Holder, it being understood, however, that the
Company shall not, in connection with any one such action or proceeding or
separate but substantially similar or related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for such Indemnified Holder and any other Indemnified
Holders, which firm shall be designated in writing by such Indemnified Holders).
The Company shall not be liable for any settlement of any such action or
proceeding effected without its written consent, but if settled with its written
consent, or if there be a final judgment for the plaintiff in any such action or
proceeding, the Company agrees to indemnify and hold harmless such Indemnified
Holders from and against any loss or liability by reason of such settlement or
judgment.

               (b)  Indemnification by Holder of Registrable Securities.  Each 
                    --------------------------------------------------- 
holder of Registrable Securities agrees to indemnify and hold harmless the
Company, its directors and officers and each Person, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act to the same extent as the foregoing indemnity from the
Company to such holder, but only with respect to information relating to such
holder furnished in writing by such holder expressly for use in any Registration
Statement or Prospectus, or any amendment or supplement thereto, or any
preliminary Prospectus. In case any action or proceeding shall be brought
against the Company or its directors or officers or any such controlling person,
in respect of which indemnity may be sought against a holder of Registrable
Securities, such holder shall have the rights and duties given the Company and
the Company or its directors or officers or such controlling person shall have
the rights and duties given to each holder by Section 7(a). In no event shall
the liability of any selling holder of Registrable Securities under this Section
7(b) be greater in amount than the dollar amount of the net proceeds received by
such holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation.

     The Company shall be entitled to receive indemnities from underwriters,
selling brokers, dealer managers and similar securities industry professionals
participating in the distribution, to the same extent as provided above with
respect to information so furnished in writing by such Persons specifically for
inclusion in any Prospectus or Registration Statement or any amendment or
supplement thereto, or any preliminary Prospectus.

               (c)  Contribution.  If the indemnification provided for in this 
                    ------------                                   
Section 7 is unavailable to an indemnified party under Section 7(a) or Section
7(b) hereof (other than by reason of exceptions provided in those Sections) in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative fault of
the Company, on the one hand, and of the Indemnified Holder, on the other hand,
in connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities 

                                      14
<PAGE>
 
or expenses, as well as any other relevant equitable considerations. The
relative fault of the Company, on the one hand, and of the Indemnified Holder,
on the other hand, shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Indemnified Holder and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The amount paid or payable by a party as a result of
the losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in the second paragraph
of Section 7(a), any legal or other fees or expenses reasonably incurred by such
party in connection with investigating or defending any action or claim.

     The Company and each holder of Registrable Securities agree that it would
not be just and equitable if contribution pursuant to this Section 7(c) were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in the
immediately preceding paragraph. Notwithstanding the provisions of this Section
7(c), an Indemnified Holder shall not be required to contribute any amount in

or by selling stockholders) to an underwriter for reoffering to the public.

          2.   Securities Subject to this Agreement.
               ------------------------------------ 

               (a)  Registrable Securities.  The securities entitled to the 
                    ----------------------  
benefits of this Agreement are the Registrable Securities.

               (b)  Holders of Registrable Securities.  A Person is deemed to 
                    ---------------------------------    
be a holder of Registrable Securities whenever such Person owns Registrable
Securities or has the right to acquire such Registrable Securities, whether or
not such acquisition has actually been effected and disregarding the legal
restrictions upon the exercise of such right; provided, however, that a Person 
                                              --------  -------      
shall not be deemed to be a holder of Registrable Securities who, together with
such Person's affiliates, then holds Registrable Securities constituting less
than one percent (1%) of the then issued and outstanding Common Stock or who may
then sell all Registrable Securities owned by such holder in reliance upon Rule
144 of the Securities Act within six months pursuant to the volume restrictions
under said Rule based upon the average weekly reported trading volume of trading
(currently Rule 144(e)(1)(ii)).

          3.   Demand Registration, Piggy-Back Registration and S-3 
               ----------------------------------------------------
Registration.
- ------------ 

               (a)  Request for Registration by Holders of Registrable 
                    --------------------------------------------------
Securities.  Subject to Section 3(h) hereof, at any time after sixty (60) days 
- ----------             
after the effective date of any registration of any of the Company's securities
(subject to any additional holdback period required by the underwriter in
connection with an underwritten offering), but in no event (i) prior to the
completion of at least one effective Series B Demand Registration or (ii) within
270 days after the effective date of any Series B Registration (or such shorter
period agreed to by the underwriter (but in any event not less than 90 days)),
if the Company receives from the holders of at least 30% of the then outstanding
Registrable Securities a written request that the Company effect any
registration or qualification with respect to Registrable Securities pursuant to
this Section 3(a) (a "Demand Registration") the Company will:

                    (1)  within ten days of receipt of such a request, give
written notice of the proposed registration or qualification to all other
holders of Registrable Securities; and

                    (2)  as soon as practicable, use its best efforts to effect
such registration or qualification (including, without limitation, the execution
in the applicable Registration Statement of an undertaking to file required 
post-effective amendments, appropriate qualification under the applicable blue
sky or other state securities laws and appropriate compliance with exemptive
regulations issued under the Securities Act and any other governmental
requirements or regulations) as may be so requested and as are reasonably
necessary to permit or facilitate the sale and distribution of all or such
portion of such holder's or holders' Registrable Securities as are specified in
such request, together with all or such portion of the Registrable Securities of
any other holder or holders joining in such request, or the Company in the case
of securities requested by the Company to be registered (provided, however, the
                                                         --------  -------    
Company shall be permitted to participate in such registration only to the
extent that all Registrable Securities as are specified by any holder in a
Demand Registration request have been included in such registration), as are
specified in a written notice given to the Company within 20 days after the date
of such written notice from the Company pursuant to Section 3(a)(1); provided,
                                                                     --------  
however that the Company will not be obligated to take any action to effect any
- -------
such registration, qualification or compliance pursuant to this Section 3(a)
after the completion of three Demand Registrations as set forth in Section 3(b).

          Subject to the foregoing provisions, the Company will file a
registration statement covering the Registrable Securities so requested to be
registered as soon as practicable, but in any event within one hundred twenty
(120) days, after receipt of the request or requests of the initiating holders,
and shall use its best efforts to cause such Registration Statement and
Prospectus through which such Demand Registration is effected to remain
effective until all Registrable Securities are sold.

          Notwithstanding anything to the contrary set forth in this Agreement,
if at any time any request to register securities pursuant to this Section 3(a)
or Section 3(f), such 

                                       4
<PAGE>
 
registration would, in the good faith determination of the Board of Directors,
be substantially detrimental to the Company, then the Company may direct in
writing ("Delay Notice") to the holders of Registrable Securities that such 
          ------------                                
request of registration be delayed for a period of time not to exceed sixty (60)
days from the date of the request, which right to delay may be exercised not
more than once in any one year period. Upon receipt of a Delay Notice, the
holders of Registrable Securities requesting the Demand Registration or S-3
Registration may, upon written notice to the Company, withdraw such request.

               (b)  Effective Registration.  A registration of Registrable 
                    ----------------------             
Securities will not count as a Demand Registration until it has become effective
and all Registrable Securities included in such Demand Registration have been
sold pursuant thereto. A Demand Registration under Section 3(a) shall be
effected pursuant to a Registration Statement on Form S-3 at any time that the
Company is eligible to use such form for such purpose.

               (c)  Underwritten Offering.  If the holder or holders of a 
                    ---------------------     
majority in number of the Registrable Securities to be registered in a Demand
Registration under this Section 3 (or the holder or holders who initiated the
Demand Registration) so elect, the offering of such Registrable Securities
pursuant to such Demand Registration shall be in the form of an Underwritten
Offering. In such event, if the managing underwriter or underwriters of such
offering advise the Company and the holders in writing that in their opinion the
Registrable Securities requested to be included in such offering is sufficiently
large so as to materially and adversely affect the success of the offering, the
Company shall include in such registration the maximum amount of Registrable
Securities which in the opinion of such managing underwriter or underwriters can
be sold without any such material adverse effect.

               (d)  Selection of Underwriters.  In the event any such 
                    -------------------------    
registration is in the form of an Underwritten Offering, the investment banker
or bankers and manager or managers that will administer the offering will be
nationally recognized investment banking firm(s) selected by the Company.

               (e)  Piggy-Back Registration.  If the Company determines to file 
                    -----------------------  
a Registration Statement under the Securities Act relating to a proposed sale to
the public of shares of its securities (but excluding registrations relating
solely to employees' stock option or purchase plans or relating solely to a
transaction employing Securities and Exchange Commission Form S-4 or Form S-8 or
successor forms thereto), either for its own account or the account of a
security holder or holders, the Company shall:

                    (1)  promptly give to each holder of Registrable Securities
written notice thereof (which will include, to the extent known at the time, a
list of the jurisdictions in which the Company intends to qualify such
securities under the applicable blue sky or other state securities laws, the
proposed offering price or price range, and the plan of distribution);

                    (2)  include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the 

                                       5
<PAGE>
 
Registrable Securities specified in a written request or requests, made within
twenty days after such written notice from the Company, by holders of
Registrable Securities; and

                    (3)  use its best efforts to cause the managing underwriter
or underwriters of such proposed Underwritten Offering to permit the Registrable
Securities requested to be included in the registration statement for such
offering to be included on the same terms and conditions as any similar
securities of the Company included therein. Notwithstanding the foregoing, if
(i) holders of Series B Registrable Securities shall have requested inclusion in
such offering pursuant to their piggy-back rights and (ii) the managing
underwriter or underwriters of such offering deliver a written opinion to the
Company and the holders of such Registrable Securities that marketing
considerations require a limitation on the number of shares of Common Stock
offered in such offering, such limitation shall be allocated among all holders
of Common Stock (other than such holders, if any, initiating the registration
pursuant to demand registration rights granted by the Company, which holders
shall receive priority with respect to inclusion in such registration in
accordance with such contractual rights) and the holders of Registrable
Securities who requested inclusion in the registration as follows: (i) first,
Series B Registrable Securities shall be included in such registration in a
number equal to the greater of (A) the pro rata portion (in proportion to all
shares of Registrable Securities and other shares of Common Stock requested to
be included in the offering which are subject to such underwriter's limitation)
of Registrable Securities requested to be included in such registration and (B)
seventy-five percent (75%) of the total number of shares to be included in such
registration (other than such holders, if any, initiating the registration
pursuant to demand registration rights granted by the Company) after giving
effect to such underwriter's limitation; and (ii) second, holders of Registrable
Securities and (iii) third, any other holders of securities of the Company who
have requested to be included in such registration statement pursuant to
contractual piggy-back registration rights.

               (f)  Request for Registration on Form S-3 by Holders of 
                    --------------------------------------------------
Registrable Securities.  At any time after the Company becomes eligible to file 
- ----------------------  
a Registration Statement on Form S-3, if the Company receives from the holders
of at least 20% of the then outstanding Registrable Securities, a written
request specifying that the Company effect any registration or qualification
with respect to the Registrable Securities pursuant to this Section 3(f) (an "S-
3 Registration"), the Company will:

                    (1)  within ten days of receipt of such a request, give
written notice of the proposed registration or qualification to all other
holders of Registrable Securities; and

                    (2)  as soon as practicable, the Company shall use its best
efforts effect such registration or qualification (including, without
limitation, the execution in the applicable Registration Statement of an
undertaking to file required post-effective amendments, appropriate
qualification under the applicable blue sky or other state securities laws and
appropriate compliance with exemptive regulations issued under the Securities
Act and any other governmental requirements or regulations) as may be so
requested and as are reasonably necessary to permit or facilitate the sale and
distribution of all or such portion of such holder's or 

                                       6
<PAGE>
 
holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other holder or holders
joining in such request, or the Company in the case of securities requested by
the Company to be registered (provided, however, the Company shall be permitted
                              --------  -------                     
to participate in such registration only to the extent that all Registrable
Securities as are specified by any holder in a S-3 Registration request have
been included in such registration), as are specified in a written notice given
to the Company within 20 days after the date of such written notice from the
Company pursuant to Section 3(a)(1); provided, however that the Company will not
                                     --------  -------     
be obligated to take any action to effect any such registration, qualification
or compliance pursuant to this Section 3(f) after the completion of two (2) S-3
Registrations as set forth in Section 3(g).

          Subject to the foregoing provisions, the Company will use its best
efforts to file a registration statement covering the Registrable Securities so
requested to be registered as soon as practicable, but in any event within 120
days, after receipt of the request or requests of the initiating holders, and
shall use its best efforts to cause such Registration Statement and Prospectus
through which such S-3 Registration is effected to remain effective until all
Registrable Securities are sold.

          The Company will not be obligated to file a registration statement
pursuant to this Section 3(f), if the Company, in the good faith determination
of the Board of Directors, such registration would be substantially detrimental
to the Company.

               (g)  Effective Registration.  A registration of Registrable 
                    ----------------------   
Securities will not count as an S-3 Registration until it has become effective
and all Registrable Securities included in such S-3 Registration have been sold
pursuant thereto.

               (h)  Coordination with Series B Holders. Notwithstanding anything
                    ---------------------------------- 
to the contrary set forth herein, at such time as the holders of Registrable
Securities request a Demand Registration or an S-3 Registration hereunder, such
holders or the Company shall deliver to the holders of Series B Preferred Stock
a notice specifying: (i) the fact that such holders have delivered to the
Company a request for a Demand Registration or S-3 Registration, as the case may
be; (ii) reasonable details regarding the expected timing and amount of
securities involved in such registration, including without limitation the
expected filing date and effective date of the Registration Statement relating
to such registration, the number of Registrable Securities (and, if applicable,
other securities) expected to be included in such Registration Statement and the
expected gross proceeds of such offering; and (iii) the rights of the holders of
Series B Registrable Securities to terminate such Demand Registration or S-3
Registration by submitting to the Company a request of the holders of the
requisite number of shares of Series B Registrable Securities (as specified in
the Series B Registration Rights Agreement) for a Series B Demand Registration
(a "Series B Demand Notice") within thirty (30) days after receipt of such
notice. In the event that the holders of Series B Registrable Securities deliver
to the Company a Series B Demand Notice within such 30-day period, the Company
shall thereupon notify the holders of Registrable Securities who initiated the
request for a Demand Registration or S-3 Registration, as the case may be, that
such request is denied due to the receipt of a Series B Demand Notice, and such
request for a Demand Registration or S-3 Registration shall be deemed 

                                       7
<PAGE>
 
withdrawn; provided, however, that the holders of Series B Registrable
Securities may deliver a Series B Demand Notice and cause such a withdrawal of
such a Demand Registration or S-3 Registration no more than two times.

               (i)  Minimum Requirement for Registration.  The Company shall be
                    ------------------------------------   
obligated to effect a registration or qualification pursuant to Section 3(a) and
Section 3(f) only if the anticipated gross offering proceeds pursuant to: (1) a
Demand Registration requested pursuant to Section 3(a) hereof equals or exceeds
$10,000,000 and (2) an S-3 Registration requested pursuant to Section 3(f)
hereof equals or exceeds $1,000,000.

          4.   Hold-Back Agreements.
               -------------------- 

               (a)  Restrictions on Sale by the Holders of Registrable 
                    --------------------------------------------------
Securities.  Each holder of Registrable Securities agrees, if requested in 
- ----------              
writing by the managing underwriters in an Underwritten Offering, not to effect
any public sale or distribution of securities of the Company of the same class
as the securities included in such Registration Statement, including a sale
pursuant to Rule 144 under the Securities Act (except as part of such
Underwritten Registration), during such period subsequent to the filing of the
Registration Statement as required by the Underwriter for each Underwritten
Offering pursuant to such Registration Statement and during such other period
(not less than 90 days) following such effective date as shall be reasonably
agreed upon by the Company and the managing underwriters.

               (b)  Restrictions on Public Sale by the Company and Others.  The 
                    ----------------------------------------------------- 
Company agrees to use reasonable efforts to cause each holder of its privately
placed debt or equity securities issued by the Company at any time on or after
the date of this Agreement (other than securities issued upon the exercise or
conversion of securities outstanding as of the date hereof) to agree not to
effect any public sale or distribution of any such securities, including a sale
pursuant to Rule 144 under the Securities Act (except as part of such
Underwritten Registration, if permitted), during the ninety (90) day period
subsequent to the filing of the Registration Statement for each Underwritten
Offering and during the 180 day period following the effective date of such
Registration Statement, in each case to the extent the managing underwriter
makes a timely written request that specifically identifies such holder(s).

          5.   Registration Procedures.
               ----------------------- 

          In connection with the Company's registration obligations pursuant to
Section 3 hereof, the Company will use its best efforts to effect such
registration to permit the sale of such Registrable Securities in accordance
with the intended method or methods of disposition thereof, and pursuant thereto
the Company will as expeditiously as possible:

               (a)  prepare and file with the Securities and Exchange Commission
such amendments and post-effective amendments to any Registration Statement, and
such supplements to the Prospectus as may be required by the rules, regulations
or instructions applicable to the registration form utilized by the Company or
by the Securities Act or otherwise necessary to keep such Registration Statement
effective for the applicable period and cause the Prospectus as so supplemented
to be filed pursuant to Rule 424 under the Securities Act; and 

                                       8
<PAGE>
 
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such Registration Statement during the applicable
period in accordance with the intended methods of disposition by the sellers
thereof set forth in such Registration Statement or supplement to the
Prospectus;

               (b)  notify the counsel to the selling holders of Registrable
Securities and the managing underwriters, if any, promptly, and (if requested by
any such Person) confirm such advice in writing,

                    (1)  when the Prospectus or any Prospectus supplement or
post-effective amendment has been filed, and, with respect to the Registration
Statement or any post-effective amendment, when the same has become effective,

                    (2)  of any request by the Securities and Exchange
Commission for amendments or supplements to the Registration Statement or the
Prospectus or for additional information,

                    (3)  of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the initiation of
any proceedings for that purpose,

                    (4)  if at any time the representations and warranties of
the Company made in agreements (including underwriting agreements) to the
holders of Registrable Securities in connection with such registration, cease to
be true and correct, and

                    (5)  of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Registrable Securities for
sale in any jurisdiction or the initiation or threatening of any proceeding for
such purpose.

               (c)  use every reasonable effort to obtain the withdrawal of any
order suspending the effectiveness of the Registration Statement at the earliest
possible moment;

               (d)  if reasonably requested by the managing underwriter or
underwriters or a holder of Registrable Securities being sold in connection with
an Underwritten Offering, immediately incorporate in a Prospectus supplement or
post-effective amendment such necessary information as the managing underwriters
and the holders of a majority of the Registrable Securities being sold
reasonably request to have included therein relating to the plan of distribution
with respect to such Registrable Securities, including, without limitation,
information with respect to the amount of Registrable Securities being sold to
such underwriters, the purchase price being paid therefor by such underwriters
and with respect to any other terms of the underwritten (or best efforts
underwritten) offering of the Registrable Securities to be sold in such
offering; and make all required filings of such Prospectus supplement or post-
effective amendment as soon as notified of the matters to be incorporated in
such Prospectus supplement or post-effective amendment;

                                       9
<PAGE>
 
               (e)  at the request of any selling holder of Registrable
Securities, furnish to such selling holder of Registrable Securities and each
managing underwriter such number of conformed copies of the Registration
Statement and any post-effective amendment thereto, including financial
statements and schedules, all documents incorporated therein by reference and
all exhibits (including those incorporated by reference) as such holder may
reasonably request;

               (f)  deliver to each selling holder of Registrable Securities and
the underwriters, if any, as many copies of the Prospectus (including each
preliminary prospectus) and any amendment or supplement thereto as such Persons
may reasonably request; the Company consents to the use of the Prospectus or any
amendment or supplement thereto by each of the selling holders of Registrable
Securities and the underwriters, if any, in connection with the offering and
sale of the Registrable Securities covered by the Prospectus or any amendment or
supplement thereto;

               (g)  prior to any public offering of Registrable Securities,
register or qualify or cooperate with the selling holders of Registrable
Securities, the managing underwriters, if any, and their respective counsel in
connection with the registration or qualification of such Registrable Securities
for offer and sale under the securities or blue sky laws of such jurisdictions
as any seller or underwriter reasonably requests in writing and do any and all
other acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by the Registration
Statement; provided that the Company will not be required to qualify to do 
           --------                                         
business in any jurisdiction where it is not then so qualified or to take any
action which would subject it to general service of process in any such
jurisdiction where it is not then so subject;

               (h)  cooperate with the selling holders of Registrable Securities
and the managing underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and, if
not required by applicable law or by contract, not bearing any restrictive
legends; and enable such Registrable Securities to be in such denominations and
registered in such names as the managing underwriters may request at least two
business days prior to any sale of Registrable Securities to the underwriters;

               (i)  use its best efforts to cause the Registrable Securities
covered by the applicable Registration Statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
to enable the seller or sellers thereof or the underwriters, if any, to
consummate the disposition of such Registrable Securities;

               (j)  use its best efforts to cause all Registrable Securities
covered by the Registration Statement to be listed on each securities exchange
on which similar securities issued by the Company are then listed if requested
by the holders of a majority in number of such Registrable Securities or by the
managing underwriters, if any;

               (k)  not later than the effective date of the applicable
Registration Statement, provide a CUSIP number for all Registrable Securities
and provide the applicable 

                                      10
<PAGE>
 
trustees or transfer agents with printed certificates for the Registrable
Securities which are in a form eligible for deposit with Depository Trust
Company; and

               (l)  cooperate and assist in any filings required to be made with
the NASD and in the performance of any due diligence investigation by any
underwriter (including any "qualified independent underwriter" that is required
to be retained in accordance with the rules and regulations of the NASD).

          The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Company such
information regarding such seller and the distribution of such securities as the
Company may from time to time reasonably request in writing. Each holder of
Registrable Securities agrees by acquisition of such Registrable Securities
that, upon receipt of any notice from the Company to the effect that the
Registration Statement, the Prospectus or any document incorporated therein by
reference contains an untrue statement of material fact or omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, such holder will forthwith discontinue disposition of
Registrable Securities until such holder's receipt of the copies of the
supplemented or amended Prospectus addressing the matters giving rise to such
notice, or until it is advised in writing by the Company that the use of the
Prospectus may be resumed.

          6.   Registration Expenses. To the extent of up to four registrations,
               ---------------------      
all expenses incident to the Company's performance of or compliance with this
Agreement will be paid by the Company, regardless whether the Registration
Statement becomes effective including without limitation:

limitation, with respect to filings required to be made with the NASD);

                    (2)  fees and expenses of compliance with securities or blue
sky laws (including, without limitation, fees and disbursements of counsel for
the underwriters in connection with blue sky qualifications of the Registrable
Securities and determination of their eligibility for investment under the laws
of such jurisdictions as the managing underwriters may designate);

                    (3)  printing (including, without limitation, expenses of

<PAGE>
 
                    (6)  fees and expenses associated of other Persons retained
by the Company; and

                    (7)  fees and expenses associated with any NASD filing

without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the securities to
be registered on each securities exchange on which similar securities issued by
the Company are then listed, rating agency fees and the fees and expenses of any
Person, including special experts, retained by the Company.

          7.  Underwriting Requirements.  In connection with any offering 
               -------------------------    
involving an underwriting of shares of the Company's capital stock or, if the
managing underwriter or agent expressly consents to the inclusion in such
underwriting, other securities under the Act, the Company shall not be required
under this Section 7 to include any of a holder's Registrable Securities in such
underwriting unless such holder accepts the terms of the underwriting as agreed
upon between the Company and the underwriters selected by it.

          8.   Indemnification.
               --------------- 

               (a)  Indemnification by the Company.  The Company agrees to 
                    ------------------------------    
indemnify and hold harmless each holder of Registrable Securities, its officers,
directors, employees and Agents and each Person who controls such holder within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each such person being sometimes hereinafter referred to as an
"Indemnified Holder") from and against all losses, claims, damages, liabilities 
 ------------------                                                
and expenses (including reasonable costs of investigation and legal expenses)
arising out of or based upon any untrue statement or alleged untrue statement of
a material fact contained in any Registration Statement or Prospectus or in any
amendment or supplement thereto or in any preliminary Prospectus, or arising out
of or based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages, liabilities or
expenses arise out of or are based upon any such untrue statement or omission or
allegation thereof based upon information furnished in writing to the Company by
such holder expressly for use therein; provided, however, that the Company shall
                                       --------  -------                        
not be liable in any such case to the extent that any such loss, claim, damage,
liability or expense arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any preliminary
Prospectus if (i) such holder failed to send or deliver a copy of the Prospectus
with or prior to the delivery of written confirmation of the sale of Registrable
Securities and (ii) the Prospectus would have corrected such untrue statement or
omission; and provided, further, that the Company shall not be liable in any
              --------  ------- 
such case to the extent that any such loss, claim, damage, liability or expense
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission in the Prospectus, if such untrue 

                                      12
<PAGE>
 
statement or alleged untrue statement, omission or alleged omission is corrected
in an amendment or supplement to the Prospectus and if, having previously been
furnished by or on behalf of the Company with copies of the Prospectus as so
amended or supplemented, such holder thereafter fails to deliver such Prospectus
as so amended or supplemented prior to or concurrently with the sale of a
Registrable Security to the person asserting such loss, claim, damage, liability
or expense who purchased such Registrable Security which is the subject thereof
from such holder. This indemnity will be in addition to any liability which the
Company may otherwise have.

          If any action or proceeding (including any governmental investigation
or inquiry) shall be brought or asserted against an Indemnified Holder in
respect of which indemnity may be sought from the Company, such Indemnified
Holder shall promptly notify the Company in writing, and the Company shall
assume the defense thereof, including the employment of counsel reasonably
satisfactory to such Indemnified Holder and the payment of all expenses.  Such
Indemnified Holder shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and expenses of
such counsel shall be the expense of such Indemnified Holder unless (a) the
Company has agreed to pay such fees and expenses or (b) the Company shall have
failed to assume the defense of such action or proceeding or has failed to
employ counsel reasonably satisfactory to such Indemnified Holder in any such
action or proceeding or (c) if the representation of such Indemnified Holder by
the counsel retained by the Company would be inappropriate due to actual or
potential conflicts of interests between the Indemnified Holder and any other
party represented by such counsel in such proceeding based on written advice of
counsel made available to the Company (in which case, if such Indemnified Holder
notifies the Company in writing that it elects to employ separate counsel at the
expense of the Company, the Company shall not have the right to assume the
defense of such action or proceeding on behalf of such Indemnified Holder, it
being understood, however, that the Company shall not, in connection with any
one such action or proceeding or separate but substantially similar or related
actions or proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys at any time for such Indemnified Holder
and any other Indemnified Holders, which firm shall be designated in writing by
such Indemnified Holders). The Company shall not be liable for any settlement of
any such action or proceeding effected without its written consent, but if
settled with its written consent, or if there be a final judgment for the
plaintiff in any such action or proceeding, the Company agrees to indemnify and
hold harmless such Indemnified Holders from and against any loss or liability by
reason of such settlement or judgment.

          (b)  Indemnification by Holder of Registrable Securities.  Each holder
               --------------------------------------------------- 
of Registrable Securities agrees to indemnify and hold harmless the Company, its
directors and officers and each Person, if any, who controls the Company within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act to the same extent as the foregoing indemnity from the Company to
such holder, but only with respect to information relating to such holder
furnished in writing by such holder expressly for use in any Registration
Statement or Prospectus, or any amendment or supplement thereto, or any
preliminary Prospectus. In case any action or proceeding shall be brought
against the Company or its directors or officers or any 

                                      13
<PAGE>
 
such controlling person, in respect of which indemnity may be sought against a
holder of Registrable Securities, such holder shall have the rights and duties
given the Company and the Company or its directors or officers or such
controlling person shall have the rights and duties given to each holder by
Section 8(a). In no event shall the liability of any selling holder of
Registrable Securities under this Section 8(b) be greater in amount than the
dollar amount of the net proceeds received by such holder upon the sale of the
Registrable Securities giving rise to such indemnification obligation.

          The Company shall be entitled to receive indemnities from
underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in the distribution, to the same extent as provided
above with respect to information so furnished in writing by such Persons
specifically for inclusion in any Prospectus or Registration Statement or any
amendment or supplement thereto, or any preliminary Prospectus.

          (c)  Contribution.  If the indemnification provided for in this 
               ------------        
Section 8 is unavailable to an indemnified party under Section 8(a) or Section
8(b) hereof (other than by reason of exceptions provided in those Sections) in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative fault of
the Company, on the one hand, and of the Indemnified Holder, on the other hand,
in connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative fault of the Company, on the one hand,
and of the Indemnified Holder, on the other hand, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by the Indemnified Holder and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The amount paid or payable by
a party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include, subject to the limitations set
forth in the second paragraph of Section 8(a), any legal or other fees or
expenses reasonably incurred by such party in connection with investigating or
defending any action or claim.

          The Company and each holder of Registrable Securities agree that it
would not be just and equitable if contribution pursuant to this Section 8(c)
were determined by pro rata allocation or by any other method of allocation
which does not take account of the equitable considerations referred to in the
immediately preceding paragraph. Notwithstanding the provisions of this Section
8(c), an Indemnified Holder shall not be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities sold by such Indemnified Holder or its affiliated Indemnified Holders
and distributed to the public were offered to the public exceeds the amount of
any damages which such Indemnified Holder, or its affiliated Indemnified
Holders, has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.  No person guilty of
fraudulent 

                                      14
<PAGE>
 
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

          To the extent the terms of this Section 8 are inconsistent with those
set forth in any agreement between the Company and an underwriter, such
underwriter's agreement shall control.

          9.   Rule 144.
               -------- 

          The Company covenants that it will file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder and, at all times after the effective
date of the first registration filed by the Company which involves a sale of
securities of the Company to the general public, will take such further action
as any holder of Registrable Securities may reasonably request, all to the
extent required from time to time to enable such holder to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by (a) Rule 144 under the Securities Act, as such
Rule may be amended from time to time or (b) any similar rule or regulation
hereafter adopted by the SEC.  Upon the request of any holder of Registrable
Securities, the Company will deliver to such holder a written statement as to
whether it has complied with such information and requirements.

          10.  Participation in Underwritten Registrations.
               ------------------------------------------- 

          No holder of Registrable Securities (or its successors or assigns) may
participate in any Underwritten Registration hereunder unless such Person (a)
agrees to sell such Person's Registrable Securities on the basis provided in any
underwriting arrangements approved by the underwriters and other Persons
entitled hereunder to approve such arrangements and (b) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements.

          11.  Miscellaneous.
               ------------- 

               (a)  Remedies.  Each holder of Registrable Securities, in 
                    --------   
addition to being entitled to exercise all rights provided herein, and as
provided in the Transaction Agreements, and granted by law, including recovery
of damages, will be entitled to specific performance of its rights under this
Agreement. The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions
of this Agreement and hereby agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

               (b)  No Inconsistent Agreements.  The Company will not on or 
                    --------------------------

this Agreement the Company is not a party to any agreement, with respect to its
securities which is inconsistent with the rights granted to the holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof or impairs the rights granted hereunder. The Company has

                                      15

                    ----------------------      
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of holders
of at least 50% of the then outstanding Registrable Securities. Notwithstanding
the foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of holders of Registrable Securities whose
securities are being sold pursuant to a Registration Statement and that does not
directly or indirectly affect the rights of other holders of Registrable
Securities may be given by the holders of 50% of the Registrable Securities
being sold.

               (d)  Notices.  All notices and other communications provided for 
                    -------

parties, including, without limitation, and without the need for an express
assignment, subsequent holders of Registrable Securities.

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

together shall constitute one and the same agreement.

               (g)  Headings. The headings in this Agreement are for convenience
                    --------

               (h)  Governing Law.  This Agreement shall be governed by and

provisions contained herein, or the application thereof in any circumstance, is

enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

               (j)  Entire Agreement.  This Agreement is intended by the parties

benefits of this Agreement are the Registrable Securities.

                 (b) Holders of Registrable Securities. A Person is deemed to be
                     ---------------------------------

                 -----------------------                                      
file a Registration Statement under the Securities Act relating to a proposed
sale to the public of shares of its securities (but excluding registrations
relating solely to employees' stock option or purchase plans or relating solely
to a transaction employing Securities and Exchange Commission Form S-4 or Form
S-8 or successor forms thereto), either for its own account or the account of a
security holder or holders, the Company shall:

                 (a) promptly give to each holder of Registrable Securities
written notice thereof (which will include, to the extent known at the time, a
list of the jurisdictions in which the Company intends to qualify such
securities under the applicable blue sky or other state securities laws, the
proposed offering price or price range, and the plan of distribution);

                 (b) subject to Section 3(c) below, include in such registration
(and any related qualification under blue sky laws or other compliance), and in
any underwriting involved therein, all the Registrable Securities specified in a
written request or requests, made within twenty days after such written notice
from the Company, by holders of Registrable Securities; and

<PAGE>

underwriters of such proposed Underwritten Offering to permit the Registrable
Securities requested to be included in the Registration Statement for such
offering to be included on the same terms and conditions as any similar
securities of the Company included therein.  Notwithstanding the foregoing, if
(i) holders of Series B Registrable Securities shall have requested inclusion in
such offering pursuant to their piggy-back rights as set forth in the Series B
Registration Rights Agreement and (ii) the managing underwriter or underwriters
of such offering deliver a written opinion to the Company and the holders of
such Registrable Securities that marketing considerations require a limitation
on the number of shares of Common Stock offered in such offering, such
limitation shall be allocated among all holders of Common Stock (other than such
holders, if any, initiating the registration pursuant to demand registration
rights granted by the Company, which holders shall receive priority with respect
to inclusion in such registration in accordance with such contractual rights)
and the holders of Registrable Securities who requested inclusion in the
registration as follows: (x) first, Series B Registrable Securities shall be
included in such registration in a number equal to the greater of:  (A) the pro
rata portion (in proportion to all shares of Registrable Securities and other
shares of Common Stock requested to be included in the offering which are
subject to such underwriter's limitation) of Series B Registrable Securities
requested to be included in such registration, or (B) up to 75% of the total
number of shares to be included in such registration (other than the shares of
such holders, if any, initiating the registration pursuant to demand
registration rights granted by the Company) after giving effect to such
underwriter's limitation; (y) second, holders of Registrable Securities, pro
rata with the holders of Series A Registrable Securities, and (z) third, any
other holders of securities of the Company who have requested to be included in
such registration statement pursuant to contractual piggy-back registration
rights.

                 (a) Restrictions on Sale by the Holders of Registrable
                     --------------------------------------------------
Securities. Each holder of Registrable Securities agrees, if requested in
- ---------
writing by the managing underwriters in an Underwritten Offering, not to effect
any public sale or distribution of securities of the Company of the same class
as the securities included in such Registration Statement, including a sale
pursuant to Rule 144 under the Securities Act (except as part of such
Underwritten Registration), during such period subsequent to the filing of the
Registration Statement as required by the Underwriter for each Underwritten
Offering pursuant to such Registration Statement and during such other period
(not less than 90 days) following such effective date as shall be reasonably
agreed upon by the Company and the managing underwriters.

                 (b) Restrictions on Public Sale by the Company and Others.  The
                     -----------------------------------------------------      
Company agrees to use reasonable efforts to cause each holder of its privately
placed debt or equity securities issued by the Company at any time on or after
the date of this Agreement (other than securities issued upon the exercise or
conversion of securities outstanding as of the date hereof) to agree not to
effect any public sale or distribution of any such securities, including a sale
pursuant to Rule 144 under the Securities Act (except as part of such
Underwritten Registration, if permitted), during the ninety day period
subsequent to the filing of the Registration Statement for each Underwritten
Offering and during the 180 day period following the effective date of such
Registration Statement, in each case to the extent the managing underwriter
makes a timely written request that specifically identifies such holder(s).

          5.     Registration Procedures.
                 ----------------------- 

          In connection with any registration by the Company's pursuant to which
the provisions of Section 3 hereof apply, the Company will use its best efforts
to effect such registration to permit the sale of such Registrable Securities in
accordance with the intended method or methods of disposition thereof, and
pursuant thereto the Company will as expeditiously as possible:

                 (a) prepare and file with the Securities and Exchange
Commission such amendments and post-effective amendments to any Registration
Statement, and such supplements to the Prospectus as may be required by the
rules, regulations or instructions applicable to the registration form utilized
by the Company or by the Securities Act or otherwise necessary to keep such
Registration Statement effective for the applicable period and cause the
Prospectus as so supplemented to be filed pursuant to Rule 424 under the
Securities Act; and comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such Registration
Statement during the applicable period in accordance with the intended methods
of disposition by the sellers thereof set forth in such Registration Statement
or supplement to the Prospectus;

                 (b) notify the counsel to the selling holders of Registrable
Securities and the managing underwriters, if any, promptly, and (if requested by
any such Person) confirm such advice in writing,

                     (1) when the Prospectus or any Prospectus supplement or
post-effective amendment has been filed, and, with respect to the Registration
Statement or any post-effective amendment, when the same has become effective,

                     (2) of any request by the Securities and Exchange
Commission for amendments or supplements to the Registration Statement or the
Prospectus or for additional information,

                     (3) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the initiation of
any proceedings for that purpose,

                     (4) if at any time the representations and warranties of
the Company made in agreements (including underwriting agreements) to the
holders of Registrable Securities in connection with such registration, cease to
be true and correct, and

                     (5) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Registrable Securities for
sale in any jurisdiction or the initiation or threatening of any proceeding for
such purpose.

                 (c) use every reasonable effort to obtain the withdrawal of any
order suspending the effectiveness of the Registration Statement at the earliest
possible moment;

                 (d) at the request of any selling holder of Registrable
Securities, furnish to such selling holder of Registrable Securities and each
managing underwriter such number of

                                       5
<PAGE>
 
conformed copies of the Registration Statement and any post-effective amendment
thereto, including financial statements and schedules, all documents
incorporated therein by reference and all exhibits (including those incorporated
by reference) as such holder may reasonably request;

                 (e) deliver to each selling holder of Registrable Securities
and the underwriters, if any, as many copies of the Prospectus (including each
preliminary prospectus) and any amendment or supplement thereto as such Persons
may reasonably request; the Company consents to the use of the Prospectus or any
amendment or supplement thereto by each of the selling holders of Registrable
Securities and the underwriters, if any, in connection with the offering and
sale of the Registrable Securities covered by the Prospectus or any amendment or
supplement thereto;

                 (f) use its best efforts to cause the Registrable Securities
covered by the applicable Registration Statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
to enable the seller or sellers thereof or the underwriters, if any, to
consummate the disposition of such Registrable Securities; and

                 (g) use its best efforts to cause all Registrable Securities
covered by the Registration Statement to be listed on each securities exchange
on which similar securities issued by the Company are then listed if requested
by the holders of a majority in number of such Registrable Securities or by the
managing underwriters, if any;

          The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Company such
information regarding such seller and the distribution of such securities as the
Company may from time to time reasonably request in writing.  Each holder of
Registrable Securities agrees by acquisition of such Registrable Securities
that, upon receipt of any notice from the Company to the effect that the
Registration Statement, the Prospectus or any document incorporated therein by
reference contains an untrue statement of material fact or omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, such holder will forthwith discontinue disposition of
Registrable Securities until such holder's receipt of the copies of the
supplemented or amended Prospectus addressing the matters giving rise to such
notice, or until it is advised in writing by the Company that the use of the
Prospectus may be resumed.

          6.     Registration Expenses.  All expenses incident to the Company's
                 ---------------------                                         
performance of or compliance with this Agreement will be paid by the Company,
regardless whether the Registration Statement becomes effective including,
without limitation:

                     (1) all registration and filing fees (including, without
limitation, with respect to filings required to be made with the NASD);

                     (2) fees and expenses of compliance with securities or blue

Securities and determination of their eligibility for investment under the laws
of such jurisdictions as the managing underwriters may designate);

                     (4) fees and disbursements of counsel for the Company;

of any special audit and "cold comfort" letters required by or incident to such
performance);

                     (6) fees and expenses associated of other Persons retained
by the Company; and

                     (7) fees and expenses associated with any NASD filing
required to be made in connection with the Registration Statement (all such
expenses being herein called "Registration Expenses").

          The Company will, in any event, pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the securities to
be registered on each securities exchange on which similar securities issued by
the Company are then listed, rating agency fees and the fees and expenses of any
Person, including special experts, retained by the Company.

          7.     Indemnification.
                 --------------- 

                 (a) Indemnification by the Company. The Company agrees to
                     ------------------------------           
indemnify and hold harmless each holder of Registrable Securities, its officers,
directors, employees and Agents and each Person who controls such holder within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each such person being sometimes hereinafter referred to as an
"Indemnified Holder") from and against all losses, claims, damages, liabilities
- -------------------                                                            
and expenses (including reasonable costs of investigation and legal expenses)
arising out of or based upon any untrue statement or alleged untrue statement of
a material fact contained in any Registration Statement or Prospectus or in any
amendment or supplement thereto or in any preliminary Prospectus, or arising out
of or based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages, liabilities or
expenses arise out of or are based upon any such untrue statement or omission or
allegation thereof based upon information furnished in writing to the Company by
such holder expressly for use therein; provided, however, that the Company shall
                                       --------  -------                        
not be liable in any such case to the extent that any such loss, claim, damage,
liability or expense arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any preliminary
Prospectus if (i) such holder failed to send or deliver a copy of the Prospectus
with or prior to the delivery of written confirmation of the sale of Registrable
Securities and (ii) the Prospectus would have corrected such untrue statement or
omission; and provided, further, that the Company shall not be liable in any
              --------  -------                                             
such case to the extent that any such loss, claim, damage, liability or expense
arises out of or is based upon an untrue 

                                       7
<PAGE>
 
statement or alleged untrue statement or omission or alleged omission in the
Prospectus, if such untrue statement or alleged untrue statement, omission or
alleged omission is corrected in an amendment or supplement to the Prospectus
and if, having previously been furnished by or on behalf of the Company with
copies of the Prospectus as so amended or supplemented, such holder thereafter
fails to deliver such Prospectus as so amended or supplemented prior to or
concurrently with the sale of a Registrable Security to the person asserting
such loss, claim, damage, liability or expense who purchased such Registrable
Security which is the subject thereof from such holder. This indemnity will be
in addition to any liability which the Company may otherwise have.

          If any action or proceeding (including any governmental investigation
or inquiry) shall be brought or asserted against an Indemnified Holder in
respect of which indemnity may be sought from the Company, such Indemnified
Holder shall promptly notify the Company in writing, and the Company shall
assume the defense thereof, including the employment of counsel reasonably
satisfactory to such Indemnified Holder and the payment of all expenses.  Such
Indemnified Holder shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and expenses of
such counsel shall be the expense of such Indemnified Holder unless (a) the
Company has agreed to pay such fees and expenses or (b) the Company shall have
failed to assume the defense of such action or proceeding or has failed to
employ counsel reasonably satisfactory to such Indemnified Holder in any such
action or proceeding or (c) if the representation of such Indemnified Holder by
the counsel retained by the Company would be inappropriate due to actual or
potential conflicts of interests between the Indemnified Holder and any other
party represented by such counsel in such proceeding based on written advice of
counsel made available to the Company (in which case, if such Indemnified Holder
notifies the Company in writing that it elects to employ separate counsel at the
expense of the Company, the Company shall not have the right to assume the
defense of such action or proceeding on behalf of such Indemnified Holder, it
being understood, however, that the Company shall not, in connection with any
one such action or proceeding or separate but substantially similar or related
actions or proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys at any time for such Indemnified Holder
and any other Indemnified Holders, which firm shall be designated in writing by
such Indemnified Holders).  The Company shall not be liable for any settlement
of any such action or proceeding effected without its written consent, but if
settled with its written consent, or if there be a final judgment for the
plaintiff in any such action or proceeding, the Company agrees to indemnify and
hold harmless such Indemnified Holders from and against any loss or liability by
reason of such settlement or judgment.

                 (b) Indemnification by Holder of Registrable Securities. Each
                     --------------------------------------------------- 
holder of Registrable Securities agrees to indemnify and hold harmless the
Company, its directors and officers and each Person, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act to the same extent as the foregoing indemnity from the
Company to such holder, but only with respect to information relating to such
holder furnished in writing by such holder expressly for use in any Registration
Statement or Prospectus, or any amendment or supplement thereto, or any
preliminary Prospectus. In case any action or proceeding shall be brought
against the Company or its directors or officers or any such controlling person,
in respect of which indemnity may be sought against a holder of Registrable
Securities, such holder 

                                       8
<PAGE>
 
shall have the rights and duties given the Company and the Company or its
directors or officers or such controlling person shall have the rights and
duties given to each holder by Section 7(a). In no event shall the liability of
any selling holder of Registrable Securities under this Section 7(b) be greater
in amount than the dollar amount of the net proceeds received by such holder
upon the sale of the Registrable Securities giving rise to such indemnification
obligation.

          The Company shall be entitled to receive indemnities from
underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in the distribution, to the same extent as provided
above with respect to information so furnished in writing by such Persons
specifically for inclusion in any Prospectus or Registration Statement or any
amendment or supplement thereto, or any preliminary Prospectus.

                 (c) Contribution. If the indemnification provided for in this
                     ------------ 
Section 7 is unavailable to an indemnified party under Section 7(a) or Section
7(b) hereof (other than by reason of exceptions provided in those Sections) in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative fault of
the Company, on the one hand, and of the Indemnified Holder, on the other hand,
in connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative fault of the Company, on the one hand,
and of the Indemnified Holder, on the other hand, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by the Indemnified Holder and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The amount paid or payable by
a party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include, subject to the limitations set
forth in the second paragraph of Section 7(a), any legal or other fees or
expenses reasonably incurred by such party in connection with investigating or
defending any action or claim.

          The Company and each holder of Registrable Securities agree that it
would not be just and equitable if contribution pursuant to this Section 7(c)
were determined by pro rata allocation or by any other method of allocation
which does not take account of the equitable considerations referred to in the
immediately preceding paragraph. Notwithstanding the provisions of this Section
7(c), an Indemnified Holder shall not be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities sold by such Indemnified Holder or its affiliated Indemnified Holders
and distributed to the public were offered to the public exceeds the amount of
any damages which such Indemnified Holder, or its affiliated Indemnified
Holders, has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

          To the extent the terms of this Section 7 are inconsistent with those
set forth in any agreement between the Company and an underwriter, such
underwriter's agreement shall control.

          8.     Rule 144.
                 -------- 

          The Company covenants that it will file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder and, at all times after the effective
date of the first registration filed by the Company which involves a sale of
securities of the Company to the general public, will take such further action
as any holder of Registrable Securities may reasonably request, all to the

in subsection 2.1) as the "Company," except where the context otherwise
requires), hereby establishes the Colorado Greenhouse, Inc. 1996 Stock Option
Plan (the "Plan") for certain employees of the Company and certain consultants
to the Company.

          1.2  Purposes.  The purposes of the Plan are to provide those who are
               --------                                                        
selected for participation in the Plan with added incentive to continue in the
long-term service of the Company and to create in such persons a more direct
interest in the future success of the operations of the Company by relating
incentive compensation to increases in stockholder value, so that the income of
those participating in the Plan is more closely aligned with the income of the
Company's stockholders.  The Plan is also designed to provide a financial
incentive that will help the Company attract, retain and motivate the most
qualified employees and consultants.

          1.3  Effective Date.  The effective date of the Plan shall be November
               --------------                                                   
___, 1996 (the "Effective Date"), subject to approval by the affirmative votes
of the holders of a majority of the shares of the Company pursuant to applicable
Delaware law within one year following the Effective Date.  If the stockholders
of the Company do not approve the Plan as specified above, Options granted under
the Plan shall be deemed to be rescinded without any further action by the Board
or the Company, and the Plan shall automatically terminate.

from time to time.

               2.4  "Committee" means the committee appointed pursuant to

          The Committee shall be responsible for administration of the Plan. The

who are empowered hereunder to take actions in the administration of the Plan.
Members of the Committee shall be appointed from time to time by the Board,

notice to the Board. Unless the Board designates specific members of the

constituted that it satisfies the requirement of "disinterested administration"
imposed by Rule 16b-3 promulgated by the Securities Exchange Commission under
the Securities Exchange Act of 1934, as such rule may be amended from time to
time, and each successor applicable rule thereunder. The Committee shall
determine the form or forms of the Option Certificates and other agreements with
Option Holders which shall evidence the particular provisions, terms,
conditions, rights and duties of the Company and the Option Holders with respect

herein. The Committee may from time to time adopt such rules and regulations for
carrying out the purposes of the Plan as it may deem proper and in the best
interests of the Company. The Committee may correct any defect, supply any
omission or reconcile any inconsistency in the Plan or in any agreement entered
into hereunder in the manner and to the extent it shall deem expedient and it
shall be the sole and final judge of such expediency. No member of the Committee
shall be liable for any action or determination made in good faith. The
determinations, interpretations and other actions of the Committee pursuant to
the provisions of the Plan shall be binding and conclusive for all purposes on
all persons.


                                   ARTICLE 4

                           STOCK SUBJECT TO THE PLAN

          4.1  Number of Shares.  The total number of Shares as to which Options
               ----------------                                                 
may be granted pursuant to the Plan shall be 1,580,135 in the aggregate.  Such
number shall be adjusted in accordance with the provisions of Section 4.2.
Shares issued upon the exercise of Options shall be applied to reduce the
maximum number of Shares remaining available for use under the Plan.  Shares
underlying expired or terminated and unexercised Options are available for grant
of Options under the Plan.  The Company shall at all times during the term of
the Plan and while any Options are outstanding retain as authorized and unissued
Stock, or as treasury Stock, at least the number of Shares from time to time
required under the provisions of the Plan, or otherwise assure itself of its
ability to perform its obligations hereunder.

          4.2  Adjustments for Stock Split, Stock Dividend, Etc.  If the Company
               -------------------------------------------------                
shall at any time increase or decrease the number of its outstanding Shares by
means of payment of a stock dividend or any other distribution upon such Shares
payable in Stock, or through a stock split, subdivision, consolidation,
combination, reclassification or recapitalization involving the Stock, or change
in any way the rights and privileges of such Shares, then the numbers, rights
and privileges of the following shall be increased, decreased or changed in like
manner as if the corresponding Shares had been issued and outstanding, fully
paid and nonassessable at the time of such occurrence:  (a) the Shares as to
which Options may be granted under the Plan; and (b) the Shares then subject to
each outstanding Option.  Upon any occurrence described in this Section 4.2, the
total Option Price under each then outstanding Option shall remain unchanged but
shall be apportioned ratably over the increased or decreased number of Shares
subject to the Option.

          4.3  Adjustments for Certain Distributions of Property.  If the
               -------------------------------------------------         
Company shall at any time distribute with respect to its Stock assets or
securities of other persons (excluding cash dividends or distributions payable
out of capital surplus and dividends or other distributions referred to in
Section 4.2 or 4.4), the Option Price of outstanding Options shall be adjusted
to reflect the fair market value of the assets or securities distributed, the
Company shall provide for the delivery upon exercise of such Options of cash in
an amount equal to the fair market value of the assets or securities distributed
or a combination of such actions shall be taken, all as 

                                       4
<PAGE>
 
determined by the Committee in its discretion. Fair market value of the assets
or securities distributed for this purpose shall be as determined by the
Committee.

          4.4  Distributions of Capital Stock and Indebtedness.  If the Company
               -----------------------------------------------                 
shall at any time distribute with respect to its Stock shares of its capital
stock (other than Stock) or evidences of indebtedness, then a proportionate part
of such capital stock and evidences of indebtedness shall be set aside for each
outstanding Option and, upon the exercise of such Option, delivered to the
Option Holder.

          4.5  No Rights as Stockholder.  An Option Holder shall have none of
               ------------------------                                      
the rights of a stockholder with respect to the Shares subject to an Option
until such Shares are transferred to the Option Holder upon the exercise of such
Option.  Except as provided in this Article 4, no adjustment shall be made for
dividends, rights or other property distributed to stockholders (whether
ordinary or extraordinary) for which the record date is prior to the date such
Shares are so transferred.

          4.6  Fractional Shares.  No adjustment or substitution provided for in
               -----------------                                                
this Article 4 shall require the Company to issue a fractional share.  The total
substitution or adjustment with respect to each Option shall be limited by
deleting any fractional share.

          4.7  Determination by the Committee, Etc.  Adjustments under this
               ------------------------------------                        
Article 4 shall be made by the Committee, whose determinations with regard
thereto shall be final and binding.


                                   ARTICLE 5

                                 PARTICIPATION

          In accordance with the provisions of the Plan, the Committee shall, in
its sole discretion, select Option Holders from among Eligible Employees and
Eligible Consultants to whom Options will be granted and shall specify the
number of Shares subject to each Option and such other terms and conditions of
each Option as the Committee may deem necessary or desirable and consistent with
the terms of the Plan.  Eligible Employees shall be selected from the employees
of the Company who are performing services in the management, operation and
growth of the Company, and contribute, or are expected to contribute, to the
achievement of long-term corporate objectives.  Eligible Consultants shall be
selected from the consultants and other individuals who provide services to the
Company with respect to the operation and growth of the Company and who
contribute, or are expected to contribute, to the achievement of long-term
corporate objectives.  Eligible Employees and Eligible Consultants may be
granted from time-to-time one or more Options.  The grant of each such Option
shall be separately approved by the Committee, and receipt of one such Option
shall not result in automatic receipt of any other Option.  Upon determination
by the Committee that an Option is to be granted to an Eligible Employee or
Eligible Consultant, written notice shall be given to such person, specifying
the terms, conditions, rights and duties related thereto.

                                 STOCK OPTIONS

          6.1  Grant of Options to Eligible Employees and Eligible Consultants.
               --------------------------------------------------------------- 
Coincident with or following designation for participation in the Plan, Eligible
Employees, Eligible Consultants and members of the Board of Directors may be
granted one or more Options.  The Committee in its sole discretion shall
designate whether an Option is to be considered an Incentive Stock Option or a
Non-Qualified Option.  Incentive Stock Options may be granted only to Eligible
Employees.  The Committee may grant both an Incentive Stock Option and a Non-
Qualified Option to an Eligible Employee at the same time or at different times.
Incentive Stock Options and Non-Qualified Options, whether granted at the same
or different times, shall be deemed to have been awarded in separate grants and
shall be clearly identified, and in no event shall the exercise of one Option
affect the right to exercise any other Option or affect the number of Shares for
which any other Option may be exercised.  An Option shall be considered as
having been granted on the date specified in the grant resolution of the
Committee.  Notwithstanding anything to the contrary contained in this Plan, the
maximum number of Shares that may be granted under this Plan to any one
individual shall not exceed 450,000 shares.

          6.2  Option Certificates.  Each Option granted under the Plan shall be
               -------------------                                              
evidenced by a written stock option certificate (an "Option Certificate") issued
in the name of the Option Holder and in such form as may be approved by the
Committee.  The Option Certificate shall incorporate and conform to the terms
and conditions set forth herein, as well as such other terms and conditions, not
inconsistent herewith, as the Committee may consider appropriate in each case.

          6.3  Certain Option Terms.  Options granted pursuant to the Plan shall
               --------------------                                             
have terms and conditions consistent with the following in addition to the terms
and conditions set forth elsewhere herein:

               (a)  Number of Shares.  Each Option shall relate to a specified
number of Shares determined by the Committee.

               (b)  Price. Each Option shall have an Option Price that is
determined by the Committee. Incentive Stock Options shall have an Option Price
that is equal to or greater than the Fair Market Value of the Stock on the date
the Option is granted.

               (c)  Duration and Exercise of Options. Each Option shall relate
to a specified period of time, as determined by the Committee, within which the
Option may be exercised by the Option Holder (the "Option Period"). The Option
Period must end, in all cases, not more than ten years from the date the Option
is granted. Each Option shall become exercisable (vest) over such period of
time, if any, as is determined by the Committee.


                                      6
<PAGE>
 
               (d)  Termination of Employment or Service, Death, Disability,
Etc. The Committee may specify the period during which an Option may be
exercised following termination of the employment of an Eligible Employee or
termination of the relationship with an Eligible Consultant. The effect of this
subsection 6.3(d) shall be limited to determining the consequences of a
termination and nothing in this subsection 6.3(d) shall restrict or otherwise
interfere with the Company's discretion with respect to the termination of any
person's employment or other relationship. If the Committee does not so specify,
the following shall apply:

                    (i)   If the employment or consulting relationship of an
          Option Holder by or with the Company terminates for any reason other
          than death or Disability within six months after the date the Option
          is granted or if the employment or consulting relationship of the
          Option Holder by or with the Company is terminated within the Option
          Period for cause, as determined by the Company, the Option shall
          thereafter be void for all purposes.  As used in this subsection
          6.3(d), "cause" shall mean a gross violation, as determined by the
          Company, of the Company's established policies and procedures.

                    (ii)  If the employment or consulting relationship of the
          Option Holder terminates because the Option Holder becomes Disabled
          within the Option Period, the Option may be exercised by the Option
          Holder (or, in the case of his or her death after becoming Disabled,
          by those entitled to do so under his or her will or by the laws of
          descent and distribution) within one year following such termination
          (if otherwise within the Option Period), but not thereafter.  In any
          such case, the Option may be exercised only as to the Shares as to
          which the Option had become vested and exercisable on or before the
          date of termination because of Disability.

                    (iii) If the Option Holder dies within the Option Period,
          while employed by the Company, while a consultant to the Company or
          within the three-month period referred to in (iv) below, the Option
          may be exercised by those entitled to do so under his or her will or
          by the laws of descent and distribution within one year following his
          or her death (if otherwise within the Option Period), but not
          thereafter.  In any such case the Option may be exercised only as to
          the Shares as to which the Option had become vested and exercisable on
          or before the date of the Option Holder's death.

                    (iv)  If the employment or consulting relationship of the
          Option Holder by or with the Company terminates within the Option
          Period for any reason other than for cause, Disability or death, and
          such termination occurs more than six months after the Option is
          granted, the Option may be exercised by the Option Holder within three
          months following the date of such termination (if otherwise within the
          Option Period), but not thereafter.  In any such case, the Option may
          be exercised only as to the Shares as to which the Option had become
          vested and exercisable on or before the date of termination.

                                       7
<PAGE>
 
                    (v)   In all of the foregoing cases, the Option may only be
          exercised with respect to Shares as to which the Option had become
          vested on or before the date of termination of employment.

               (e)  Consideration for Grant of Option. The Committee may require
each Eligible Employee who is granted an Option to agree to remain in the
employment of the Company, at the pleasure of the Company, for a continuous
period of time after the date an Option is granted, at the salary rate or other
compensation in effect on the date of such agreement or at such changed rate as
may be fixed, from time to time, by the Company. Nothing in this paragraph shall
offset or impair the Company's right to terminate the employment of any
employee. The Committee may require each Eligible Consultant who is granted an
Option to agree to comply with all of the terms and conditions or specified
terms and conditions of the agreement between such Eligible Consultant and the
Company. If an Option Holder violates any such agreement, the Company may, in
its sole discretion, rescind the transfer of any Shares to the Option Holder
pursuant to the exercise of any portion of the Option. Upon notice of any such
rescission, the Option Holder will deliver promptly to the Company certificates
representing the Shares, duly endorsed for transfer to the Company. All Shares
issued pursuant to the Plan shall be subject to the terms and conditions,
including the Company's right to purchase the Shares in certain circumstances,
set forth in the Company's shareholder agreement (the "Shareholder Agreement").
The Shareholder Agreement shall be executed by the Company and each Eligible
Employee or Eligible Consultant prior to the issuance of any Shares pursuant to
the exercise of any portion of the Option.

               (f)  Exercise, Payments, Etc.

                    (i)  Manner of Exercise.  The method for exercising each
          Option granted hereunder shall be by delivery to the Company of
          written notice specifying the number of Shares with respect to which
          such Option is exercised.  If the Shares of Stock covered by this
          Option are not issued in a registered transaction, the issuance of the
          Shares will be subject to the receipt by the Company of appropriate
          investment representations from the Option Holder and the certificate
          representing such Shares of Stock shall bear such legends as may be
          required by the Company in order to assure compliance with federal and
          state securities laws.

                    The purchase of such Shares shall take place at the
          principal offices of the Company within thirty days following delivery
          of such notice, at which time the Option Price of the Shares shall be
          paid in full by any of the methods set forth below or a combination
          thereof.  The Option shall be exercised when the Option Price for the
          number of shares as to which the Option is exercised is paid to the
          Company in full.  A properly executed certificate or certificates
          representing the Shares shall be delivered to or at the direction of
          the Option Holder upon payment therefor.  If Options on less than all
          shares evidenced by an Option Certificate are exercised, the Company
          shall deliver a 

                                       8
<PAGE>
 
          new Option Certificate evidencing the Option on the remaining shares
          upon delivery of the Option Certificate for the Option being
          exercised.

                    (ii) Manner of Payment.  The Option Price shall be paid by
          any of the following methods or any combination of the following
          methods at the option of the Option Holder, or by any other method
          approved by the Committee upon the request of the Option Holder:  (A)
          cash; (B) certified, cashier's or other check acceptable to the
          Company, payable to the order of the Company; or (C) if permitted by
          the Committee in its sole discretion, through delivery to the Company
          of the Option Holder's full recourse promissory note, containing such
          provisions for repayment, interest and security as shall be specified
          by the Committee.

               (g)  Withholding.

                    (i)  Non-Qualified Options.  Upon exercise of an Option, the
          Option Holder shall make appropriate arrangements with the Company to
          provide for the amount of additional withholding required by Sections
          3102 and 3402 of the Code and applicable state income tax laws.

                    (ii) Incentive Options.  If an Option Holder makes a
          disposition (as defined in Section 424(c) of the Code) of any Stock
          acquired pursuant to the exercise of an Incentive Stock Option prior
          to the expiration of two years from the date on which the Incentive
          Stock Option was granted or prior to the expiration of one year from
          the date on which the Option was exercised, the Option Holder shall
          send written notice to the Company at its principal office in Boulder,
          Colorado (Attention:  Chief Financial Officer) of the date of such
          disposition, the number of shares disposed of, the amount of proceeds
          received from such disposition and any other information relating to
          such disposition as the Company may reasonably request.  The Option
          Holder shall, in the event of such a disposition, make appropriate
          arrangements with the Company to provide for the amount of additional
          withholding, if any, required by Sections 3102 and 3402 of the Code
          and applicable state income tax laws.

          6.4  Restrictions on Incentive Stock Options.
               --------------------------------------- 

               (a)  Initial Exercise. The aggregate Fair Market Value of the
Shares with respect to which Incentive Stock Options are exercisable for the
first time by an Option Holder in any calendar year, under the Plan or
otherwise, shall not exceed $100,000. For this purpose, the Fair Market Value of
the Shares shall be determined as of the date of grant of the Option.

               (b)  Ten Percent Stockholders. Incentive Stock Options granted to
an Option Holder who is the holder of record of stock of the Company having more
than 10% of the total combined voting power of all classes of outstanding stock
of the Company shall have an 

                                       9
<PAGE>
 
Option Price equal to 110% of the Fair Market Value of the Shares on the date of
grant of the Option and the Option Period for any such Option shall not exceed
five years.

                           CORPORATE REORGANIZATION

          7.1  Reorganization.  Upon the occurrence of any of the following
               --------------                                              
events, if the notice required by Section 7.2 shall have first been given, the
Plan and all Options then outstanding hereunder shall automatically terminate
and be of no further force and effect whatsoever, without the necessity for any
additional notice or other action by the Board or the Company:  (a) the merger
or consolidation of the Company with or into another corporation (other than a
consolidation or merger in which the Company is the continuing corporation and
which does not result in any reclassification or change of outstanding shares of
Stock); or (b) the sale or conveyance of the property of the Company as an
entirety or substantially as an entirety (other than a sale or conveyance in
which the Company continues as a holding company of an entity or entities that
conduct the business or businesses formerly conducted by the Company); or (c)
the dissolution or liquidation of the Company.

          7.2  Required Notice.  At least 30 days' prior written notice of any
               ---------------                                                
event described in Section 7.1 shall be given by the Company to each Option
Holder, unless in the case of the events described in clauses (a) or (b) of
Section 7.1, the Company, or the successor or purchaser, as the case may be,
shall make adequate provision for the assumption of the outstanding Options or
the substitution of new options for the outstanding Options on terms comparable
to the outstanding Options except that the Option Holder shall have the right
thereafter to purchase the kind and amount of securities or property or cash
receivable upon such merger, consolidation, sale or conveyance by a holder of
the number of Shares that would have been receivable upon exercise of the Option
immediately prior to such merger, consolidation, sale or conveyance (assuming
such holder of Stock failed to exercise any rights of election and received per
share the kind and amount received per share by a majority of the non-electing
shares).  The provisions of this Article 7 shall similarly apply to successive
mergers, consolidations, sales or conveyances.  Such notice shall be deemed to
have been given when delivered personally to an Option Holder or when mailed to
an Option Holder by registered or certified mail, postage prepaid, at such
Option Holder's address last known to the Company.

          7.3  Acceleration of Exercisability.  Option Holders notified in
               ------------------------------                             
accordance with Section 7.2 may exercise their Options at any time before the
occurrence of the event requiring the giving of notice (but subject to
occurrence of such event), to the extent such Options are exercisable and any
vesting requirements with respect to periods of employment or otherwise have
been satisfied.  In addition, the Committee, in its sole discretion, may
accelerate the vesting of any Option, in full or in part, in the event of an
occurrence described in this Article 7.

                          EMPLOYMENT; TRANSFERABILITY

          8.1  Employment.  Nothing contained in the Plan or in any Option
               ----------                                                 
granted under the Plan shall confer upon any Option Holder any right with
respect to the continuation of his or her employment by or service with the
Company, or interfere in any way with the right of the Company, subject to the
terms of any separate employment agreement or other contract to the contrary, at
any time to terminate the employment or service of such Option Holder or to
increase or decrease the compensation of the Option Holder from the rate in
existence at the time of the grant of an Option.  The Committee shall determine
whether an authorized leave of absence, or absence in military or government
service, shall constitute a termination of employment.

          8.2  Other Employee Benefits.  The amount of any compensation deemed
               -----------------------                                        
to be received by an Option Holder as a result of the exercise of an Option
shall not constitute "earnings" with respect to which any other employee
benefits of such person are determined, including without limitation benefits
under any pension, profit sharing, life insurance or salary continuation plan.

          8.3  Transferability.   No right or interest of any Option Holder in
               ---------------                                                
an Option granted pursuant to the Plan shall be assignable or transferable
during the lifetime of the Option Holder, either voluntarily or involuntarily,
or be subjected to any lien, directly or indirectly, by operation of law, or
otherwise, including execution, levy, garnishment, attachment, pledge or
bankruptcy.  In the event of an Option Holder's death, an Option Holder's rights
and interests in Options shall be transferable by will or pursuant to the laws
of descent and distribution.  Each Option granted under the Plan shall be
exercisable during the Holder's lifetime only by the Option Holder or, in the
event of Disability or incapacity, by the Option Holder's guardian or legal
representative.


                                   ARTICLE 9

                          SECURITIES LAW RESTRICTIONS

          Each Option shall be subject to the requirement that if at any time
counsel to the Company shall determine that the listing, registration or
qualification of the Shares subject to such Option upon any securities exchange
or under any state or federal law, or the consent or approval of any
governmental or regulatory body, is necessary as a condition of, or in

such shares until expiration or termination of the Option as provided in the
Plan.  A form of written notice for the purpose of exercising the Option is
attached.  Pursuant to the Plan, the Company may require the Holder to execute a

term of this Agreement or that come into Employee's possession in connection
with Employee's performance of services under this Agreement are and shall
remain the Company's property.  Employee shall not copy or use any such
documents or Confidential Information for any purpose not relating directly to
Employee's duties under this Agreement, nor shall Employee market or in any way
provide or make available to any party other than the Company any of the
Confidential Information, except pursuant to prior written authorization from
the Company. Upon the termination of this Agreement for any reason and
regardless of the circumstances of such termination or the existence of any
dispute between Employee and the Company following or concerning the termination
of Employee's employment, or upon the request of the Company, its successors or
assigns, Employee shall immediately deliver to the Company or its designee (and
will not keep in Employee's possession or deliver to anyone else) any and all
devices, records, data, notes, reports, proposals, lists, correspondence,
specifications, drawings, blueprints, sketches, materials, equipment, other
documents or property, or reproductions of any aforementioned items belonging to
the Company, its successors or assigns.  Notwithstanding any other provision of
this Agreement, this Agreement shall not bar Employee from complying with any
subpoena or court order, provided that prior to doing so Employee shall give the
Company's Manager prior written notice, at the Company's principal place of
business, of Employee's receipt of any such subpoena or court order as far as
possible in advance of the appearance time set forth in the subpoena or court
order.

               (e)  Employee acknowledges that the Company has received and in
the future will receive from third parties confidential or proprietary
information, and that the Company must maintain the confidentiality of such
information and use it only for proper purposes. Employee shall not use or
disclose any such information except as permitted by the Company or the third
party to whom the information belongs.

               (f)  Employee shall not, during Employee's employment with the
Company, improperly use or disclose any proprietary information or trade secrets
belonging to any former employer or any third party to whom Employee owes a duty
of nondisclosure.

          7.   Covenants Not to Compete or Interfere.
               ------------------------------------- 

               (a)  During the term of this Agreement (or, if longer, during the
term of Employee's employment with the Company or any of its affiliates) and for
a period of eighteen months after termination of this Agreement (or, if later,
termination of Employee's employment with the Company or any of its affiliates),
Employee shall not, within the United States or within a 50 mile radius of any
area where the Company is or contemplates doing business at the time of such
termination, directly or indirectly, own, manage, operate, control, be employed
by, participate in or be connected in any manner

                                       4
<PAGE>
 
with the ownership, management, operation or control of any business that has
services or products competitive or similar to the services or products of the
Company or its affiliates.

               (b)  During the term of this Agreement (or, if longer, during the
term of Employee's employment with the Company or any of its affiliates) and for
a period of eighteen months after termination of this Agreement (or, if later,
termination of Employee's employment with the Company or any of its affiliates),
Employee shall not (i) directly or indirectly cause or attempt to cause any
employee of the Company or of any of its affiliates to leave the employ of the
Company or any affiliate, (ii) in any way interfere with the relationship
between the Company and any employee or between an affiliate and any employee of
the affiliate, (iii) directly or indirectly hire any employee of the Company or
of any affiliate to work for any organization of which Employee is an officer,
director, employee, consultant, independent contractor or owner of an equity or
other financial interest, or (iv) interfere or attempt to interfere with any
transaction in which the Company or any of its affiliates was involved during
the term of this Agreement or his employment.

               (c)  Employee acknowledges that through his employment with the
Company he will acquire access to information suited to immediate application by
a business in competition with the Company. Accordingly, Employee considers the
foregoing restrictions on his future employment or business activities in all
respects reasonable. Employee specifically acknowledges that the Company and its
licensees, as well as the Company's competitors, distribute their products
throughout the United States. Employee therefore specifically consents to the
foregoing geographic restriction on competition and believes that such a
restriction is reasonable, given the scope of the Company's business and the
nature of Employee's position with the Company.

               (d)  Employee acknowledges the following provisions of Colorado
law, set forth in Colorado Revised Statutes (S) 8-2-113(2):

          "Any covenant not to compete which restricts the right of any person
          to receive compensation for performance of skilled or unskilled labor
          for any employer shall be void, but this subsection (2) shall not
          apply to:

                    (a)  Any contract for the purchase and sale of a business or
                         the assets of a business;

                    (b)  Any contract for the protection of trade secrets;

                    (c)  Any contract provision providing for the recovery of
                         the expense of educating and training an employee who
                         has served an employer for a period of less than two
                         years;

                    (d)  Executive and management personnel and officers and
                         employees who constitute professional staff to
                         executive and management personnel."

Employee acknowledges that this Agreement is a contract for the protection of
trade secrets under (S) 8-2-113(2)(b), and is intended to protect the
confidential information and trade secrets of the Company; and that Employee is
an executive and management employee or professional staff to executive or
management personnel, within the meaning of (S) 8-2-113(2)(d).

                                       5
<PAGE>
 
               (e)  Employee acknowledges and is prepared for the possibility
that his standard of living may be reduced during the noncompetition period
provided in this Section following the termination of this Agreement, and fully
accepts any risk associated with that possibility.


          8.   Injunctive Relief.  Upon a breach or threatened breach by
               -----------------                                        
Employee of any of the provisions of Sections 6 or 7 of this Agreement, the
Company shall be entitled to an injunction restraining Employee from such
breach.  Nothing herein shall be construed as prohibiting the Company from
pursuing any other remedies for such breach or threatened breach, including
recovery of damages from Employee.

          9.   Waiver of Breach.  A waiver by the Company of a breach of any
               ----------------                                             
provision of this Agreement by Employee shall not operate or be construed as a
waiver of any subsequent breach by Employee.

          10.  Severability.  It is the desire and intent of the parties that
               ------------                                                  
the provisions of this Agreement shall be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought.  Accordingly, if any particular provision or
portion of this Agreement shall be adjudicated to be invalid or unenforceable,
this Agreement shall be deemed amended to delete therefrom the portion thus
adjudicated to be invalid or unenforceable, such deletion to apply only with
respect to the operation of this Section in the particular jurisdiction in which
such adjudication is made.

          11.  Inventions and Discoveries.
               -------------------------- 

               (a)  Employee agrees to disclose promptly to the Company the full
details of any and all ideas, processes, recipes, trademarks and service marks,
works, inventions, discoveries, marketing and business ideas, and improvements
or enhancements to any of the foregoing, that Employee conceives, develops or
creates alone or with the aid of others during the term of Employee's employment
with the Company (whether or not conceived, developed or created during regular
working hours) that: (i) relate to the Company's business; (ii) result from any
work performed by Employee for the Company; (iii) involve the use of the
Company's equipment, supplies, facilities, or trade secret information; (iv)
result from or are suggested by any work done at the Company's request or by any
Company employee other than Employee, or relate to any problems specifically
assigned to Employee; or (v) result from Employee's access to any of the
Company's memoranda, notes, records, drawings, sketches, models, maps, customer
lists, research results, data, formula, specifications, inventions, processes,
recipes, equipment, or the like.

               (b)  Employee shall assign to the Company, without further
consideration, Employee's entire right to any concept, idea or invention
described in the preceding subsection, which shall be the sole and exclusive
property of the Company whether or not patentable.  Employee also acknowledges
that all original works of authorship which are made by Employee (solely or
jointly with others), within the scope of Employee's employment, and which are
protectable by copyright, are "works made for hire," as that term is defined in
the United States Copyright Act (17 U.S.C. (S) 101).  To the extent that any
such works, by operation of law, cannot be "works made for hire," Employee
hereby assigns to the Company all right, title, and interest in and to such
works and to any related copyrights.

          12.  Notices.  All communications, requests, consents and other
               -------

than Employee], and if to Employee, by hand delivery to him.

          13.  Governing Law.  This Agreement shall be governed by and construed

                             EMPLOYMENT AGREEMENT
                             --------------------

     THIS EMPLOYMENT AGREEMENT (this "Agreement"), dated effective October 15,
1997, is between Colorado Greenhouse Holdings, Inc., a Delaware corporation (the
"Company"), and James R. Rinella ("Employee").

     In consideration of the mutual covenants and agreements contained herein,
the parties hereto agree as follows:

     1.   Employment.  The Company hereby employs Employee and Employee hereby
          ----------                                                          
agrees to be employed by the Company for the period and upon the terms and
conditions hereinafter set forth.

     2.   Capacity and Duties.  Employee shall be employed by the Company as its
          -------------------                                                   
Chief Executive Officer.  During his employment Employee shall perform the
duties and bear the responsibilities commensurate with his position and shall
serve the Company faithfully and to the best of his ability, under the direction
of the board of directors of the Company.  Employee shall devote his entire
working time, attention and energies to the business of the Company.  His
actions shall at all times be such that they do not discredit the Company or its
products and services.  Except for his involvement in personal investments,
provided such involvement does not require any significant services on his part,
Employee shall not engage in any other business activity or activities that
require significant personal services by Employee or that, in the judgment of
the board of directors, may conflict with the proper performance of Employee's
duties hereunder.

     3.   Compensation.
          ------------ 

          (a) For all services rendered by Employee the Company shall pay
Employee during the term of this Agreement an annual salary as set forth herein,
payable semimonthly in arrears. Employee's initial annual salary shall be
$200,000.  During the term of this Agreement, the amount of Employee's salary
shall be reviewed at periodic intervals and, upon agreement of the parties
hereto, appropriate adjustments in such salary may be made.

          (b) In addition to salary payments as provided in Section 3(a), the
Company shall provide Employee, during the term of this Agreement, with the
benefits of such insurance plans, hospitalization plans and other employee
fringe benefit plans as shall be generally provided to employees of the Company
and for which Employee may be eligible under the terms and conditions thereof.
Nothing herein contained shall require the Company to adopt or maintain any such
employee benefit plans.

          (c) During the term of this Agreement, except as otherwise provided in
Section 5(b), Employee shall be entitled to sick leave consistent with the
Company's customary sick leave and vacation policies.  Employee shall be
entitled to three weeks annual vacation.

          (d) During the term of this Agreement the Company shall reimburse
Employee for all reasonable out-of-pocket expenses incurred by Employee in
connection with the business of the Company and in the performance of his duties
under this Agreement upon presentation to the Company of an itemized accounting
of such expenses with reasonable supporting data.  Without limiting the
foregoing, the Company shall reimburse Employee for the cost of one home
telephone line plus facsimile equipment.
<PAGE>
 
          (e) The Company shall reimburse Employee for reasonable moving
expenses (including the cost of one trip by Employee and his spouse to survey
the Front Range housing market) not to exceed $25,000 within 30 days after
presentation of reasonable documentation thereof.

          (f) The Company's compensation committee (the "Compensation
Committee") shall establish a performance based bonus plan that will provide for
annual bonuses of up to 50% of Employee's annual salary based upon achieving
certain milestones.  Currently, as to Employee, the Compensation Committee
expects to authorize a bonus of $100,000 if annual EBT projections are achieved,
plus $10,000 for each additional $500,000 in EBT above projections.

          (g) The Company shall grant to Employee the option to acquire shares
of the Company's common stock as provided in the Incentive and Nonincentive
Stock Option Certificates (the "Certificate") attached as Exhibits A-1 and A-2.
In addition, the Company may grant to Employee such other stock options as may
be approved by the Compensation Committee.

          (h) The Company shall negotiate a vehicle and mileage allowance with
and for Employee.

     4.   Term/Severance.
          -------------- 

          (a) Unless sooner terminated in accordance with Section 5, the term of
this Agreement shall be from the date of this Agreement until December 31, 2002.
The provisions of Sections 6, 7, 8 and 10 shall remain in full force and effect
for the time periods specified in such Sections notwithstanding the termination
of this Agreement.

          (b) If this Agreement is terminated by the Company prior to the end of
its term pursuant to any provision other than Section 5(d), then the Company
shall pay to Employee one year's annual salary in 12 monthly installments as
severance.  The Company shall deduct from such severance payment all applicable
deductions and withholdings.

     5.   Termination.
          ----------- 

          (a) If Employee dies during the term of this Agreement, the Company
shall pay his estate the compensation that would otherwise be payable to him for

Company's stock option plan and the Certificate vested stock option may be
exercised by Employee's heirs.

performing his duties by reason of illness or incapacity for a continuous period
of 120 days the Company may terminate this Agreement upon 30 days' prior notice
thereof to Employee or his duly appointed legal representative.  For the
purposes of this Section 5(b), a period of illness or incapacity shall be deemed
"continuous" notwithstanding Employee's performance of his duties during such
period for continuous periods of less than 15 days in duration.

          (c) The Company may terminate this Agreement upon at least 30 days'
prior notice to him upon the happening of any of the following events:

          transaction of 51% or more of the outstanding voting stock of the
          Company to or with a person, firm or corporation not then an affiliate
          of the Company;

                    (iii)  a bona fide decision by the Company to terminate its
          business and liquidate its assets (but only if such liquidation is not
          part of a plan to carry on the Company's business through its
          shareholders);

                    (iv)   the merger or consolidation of the Company in a
          transaction in which the shareholders of the Company receive less than

                    (v)    the damage, destruction or other loss (including that
          caused by condemnation or similar proceedings) to the Company's
          facilities to such an extent that the Company is unable to conduct the
          ordinary course of its business for a continuous period of 90 days or
          more.

          (f)  Either party may elect to terminate this Agreement by giving
notice to the other party at least 60 days prior to any anniversary of the
execution of this Agreement.

For purposes of this Agreement, the term "affiliate" or "affiliates" means a

intermediaries, controls, is controlled by or is under common control with the
Company.

     6.   Confidential Information.
          ------------------------ 

          (a)  As used in this Agreement, the term "Confidential Information"
shall include  all nonpublic information concerning or arising from the
Company's business, including, without limitation, trade secrets used or
developed by the Company in connection with its business; information concerning
the manner and details of the Company's operation, organization and management;
financial information and/or documents and nonpublic policies, procedures and
other printed or written material generated or used in connection with the
Company's business; the Company's business plans and strategies; the identities
of the Company's customers and the specific individual customer representatives
with whom  the Company works and details of the Company's relationship with such
customers and customer representatives; the identities of distributors,
suppliers, contractors and vendors utilized in the Company's business and

Company's business, whether proprietary to the Company or used by the Company
under license from a third party; and/or other information concerning know-how,
research, inventions, copyrights, trademarks, patents, processes, designs,
methods, concepts, prospects, customers, employees, contractors, earnings,
products, services, formulas, recipes, compositions, machines, equipment,
systems, and/or prospective and executed contracts and other business
arrangements.

          (b)  Except in connection with and in furtherance of Employee's
official duties with and on behalf of  the Company, Employee shall not at any
time or in any manner use, copy, disclose, divulge, transmit, convey, transfer
or otherwise communicate any Confidential Information to any person or entity,
either directly or indirectly, without the Company's prior written consent.

          (c)  Employee acknowledges that during the term of this Agreement,
Employee will have access to Confidential Information, all of which shall be
made accessible to Employee only in strict confidence; that unauthorized
disclosure of Confidential Information will damage the Company's business; that
Confidential Information would be susceptible to immediate competitive

Confidential Information shall at all times remain vested in the Company.
Consequently, Employee acknowledges that the restrictions contained in this
Section 6 are reasonable and necessary for the protection of the Company's
business.

          (d)  All documents or other records containing or referring to
Confidential Information that are prepared by or provided to Employee during the
term of this Agreement or that come into Employee's possession in connection
with Employee's performance of services under this Agreement are and shall

documents or Confidential Information for any purpose not relating directly to
Employee's duties under this Agreement, nor shall Employee market or in any way
provide or make available to any party other than the Company any of the
Confidential Information, except pursuant to prior written authorization from
the Company. Upon the termination of this Agreement for any reason and
regardless of the circumstances of such termination or the existence of any
dispute between Employee and the Company following or concerning the termination
of Employee's employment, or upon the request of the Company, its successors or
assigns, Employee shall immediately deliver to the Company or its designee (and
will not keep in Employee's possession or deliver to anyone else) any and all
devices, records, data, notes, reports, proposals, lists, correspondence,
specifications, drawings, blueprints, sketches, materials, equipment, other
documents or property, or reproductions of any aforementioned items belonging to
the Company, its successors or assigns. Notwithstanding any other provision of
this Agreement, this Agreement shall not bar Employee from complying with any
subpoena or court order, provided that prior to doing so Employee shall give the
Company's Manager prior written notice, at the Company's principal place of
business, of Employee's receipt of any such subpoena or court order as far as
possible in advance of the appearance time set forth in the subpoena or court
order.

          (e)  Employee acknowledges that the Company has received and in the
future will receive from third parties confidential or proprietary information,
and that the Company must maintain the confidentiality of such information and
use it only for proper purposes.  Employee shall not use or disclose any such
information except as permitted by the Company or the third party to whom the
information

                                       4

belongs.
            
          (f)  Employee shall not, during Employee's employment with the
Company, improperly use or disclose any proprietary information or trade secrets
belonging to any former employer or any third party to whom Employee owes a duty
of nondisclosure.

     7.   Covenants Not to Compete or Interfere.
          ------------------------------------- 

          (a)  During the term of this Agreement (or, if longer, during the term
of Employee's employment with the Company or any of its affiliates) and for a
period of eighteen months after termination of this Agreement (or, if later,
termination of Employee's employment with the Company or any of its affiliates),
Employee shall not, within the United States or within a 50 mile radius of any
area where the Company is or contemplates doing business at the time of such
termination, directly or indirectly, own, manage, operate, control, be employed
by, participate in or be connected in any manner with the ownership, management,
operation or control of any business that has services or products competitive
or similar to the services or products of the Company or its affiliates.

          (b)  During the term of this Agreement (or, if longer, during the term
of Employee's employment with the Company or any of its affiliates) and for a
period of eighteen months after termination of this Agreement (or, if later,
termination of Employee's employment with the Company or any of its affiliates),
Employee shall not (i) directly or indirectly cause or attempt to cause any
employee of the Company or of any of its affiliates to leave the employ of the
Company or any affiliate, (ii) in any way interfere with the relationship
between the Company and any employee or between an affiliate and any employee of
the affiliate, (iii) directly or indirectly hire any employee of the Company or
of any affiliate to work for any organization of which Employee is an officer,
director, employee, consultant, independent contractor or owner of an equity or
other financial interest, or (iv) interfere or attempt to interfere with any
transaction in which the Company or any of its affiliates was involved during
the term of this Agreement or his employment.

          (c)  Employee acknowledges that through his employment with the
Company he will acquire access to information suited to immediate application by
a business in competition with the Company. Accordingly, Employee considers the
foregoing restrictions on his future employment or business activities in all
respects reasonable. Employee specifically acknowledges that the Company and its
licensees, as well as the Company's competitors, distribute their products
throughout the United States. Employee therefore specifically consents to the
foregoing geographic restriction on competition and believes that such a
restriction is reasonable, given the scope of the Company's business and the
nature of Employee's position with the Company.

          (d)  Employee acknowledges the following provisions of Colorado law,
set forth in Colorado Revised Statutes (S) 8-2-113(2):

          "Any covenant not to compete which restricts the right of any person
          to receive compensation for performance of skilled or unskilled labor
          for any employer shall be void, but this subsection (2) shall not
          apply to:

                    (a)  Any contract for the purchase and sale of a business or
                         the assets

                                       5
<PAGE>
 
                         of a business;

                    (b)  Any contract for the protection of trade secrets;

                    (c)  Any contract provision providing for the recovery of
                         the expense of educating and training an employee who
                         has served an employer for a period of less than two
                         years;

                    (d)  Executive and management personnel and officers and
                         employees who constitute professional staff to
                         executive and management personnel."

Employee acknowledges that this Agreement is a contract for the protection of
trade secrets under (S) 8-2-113(2)(b), and is intended to protect the
confidential information and trade secrets of the Company; and that Employee is
an executive and management employee or professional staff to executive or
management personnel, within the meaning of (S) 8-2-113(2)(d).

          (e)  Employee acknowledges and is prepared for the possibility that
his standard of living may be reduced during the noncompetition period provided
in this Section following the termination of this Agreement, and fully accepts
any risk associated with that possibility.

     8.   Injunctive Relief.  Upon a breach or threatened breach by Employee of
          -----------------                                                    
any of the provisions of Sections 6 or 7 of this Agreement, the Company shall be
entitled to an injunction restraining Employee from such breach.  Nothing herein
shall be construed as prohibiting the Company from pursuing any other remedies
for such breach or threatened breach, including recovery of damages from
Employee.

     9.   Waiver of Breach.  A waiver by the Company of a breach of any
          ----------------                                             
provision of this Agreement by Employee shall not operate or be construed as a
waiver of any subsequent breach by Employee.

     10.  Severability.  It is the desire and intent of the parties that the
          ------------                                                      
provisions of this Agreement shall be enforced to the fullest extent permissible
under the laws and public policies applied in each jurisdiction in which
enforcement is sought.  Accordingly, if any particular provision or portion of
this Agreement shall be adjudicated to be invalid or unenforceable, this
Agreement shall be deemed amended to delete therefrom the portion thus
adjudicated to be invalid or unenforceable, such deletion to apply only with
respect to the operation of this Section in the particular jurisdiction in which
such adjudication is made.

     11.  Inventions and Discoveries.
          -------------------------- 

          (a)  Employee agrees to disclose promptly to the Company the full
details of any and all ideas, processes, recipes, trademarks and service marks,
works, inventions, discoveries, marketing and business ideas, and improvements
or enhancements to any of the foregoing, that Employee conceives, develops or
creates alone or with the aid of others during the term of Employee's employment
with the Company (whether or not conceived, developed or created during regular
working hours) that:  (i) relate to the Company's business; (ii) result from any
work performed by Employee for the Company; (iii) involve

                                       6
<PAGE>
 
the use of the Company's equipment, supplies, facilities, or trade secret
information; (iv) result from or are suggested by any work done at the Company's
request or by any Company employee other than Employee, or relate to any
problems specifically assigned to Employee; or (v) result from Employee's access
to any of the Company's memoranda, notes, records, drawings, sketches, models,
maps, customer lists, research results, data, formula, specifications,
inventions, processes, recipes, equipment, or the like.

          (b)  Employee shall assign to the Company, without further
consideration, Employee's entire right to any concept, idea or invention
described in the preceding subsection, which shall be the sole and exclusive
property of the Company whether or not patentable. Employee also acknowledges
that all original works of authorship which are made by Employee (solely or
jointly with others), within the scope of Employee's employment, and which are
protectable by copyright, are "works made for hire," as that term is defined in
the United States Copyright Act (17 U.S.C. (S) 101). To the extent that any such
works, by operation of law, cannot be "works made for hire," Employee hereby
assigns to the Company all right, title, and interest in and to such works and
to any related copyrights.

     12.  Notices.  All communications, requests, consents and other notices
          -------

Employee, and if to Employee, by hand delivery to him.

                      INCENTIVE STOCK OPTION CERTIFICATE
                      ----------------------------------          

    Option Holder:      James R. Rinella
    Option Price:       $4.25 per share
    Date of Grant:      October 15, 1997
    Number of Shares:   94,116

1.  This certifies that the above named Option Holder (the "Holder") is the
holder of an incentive stock option (the "Option") to acquire, at the exercise
price per share specified above, the number of shares of the $0.001 par value
common stock ("Stock"), of Colorado Greenhouse Holdings, Inc., a Delaware
corporation (the "Company"), specified above. The Option evidenced by this
Certificate is intended to qualify as an incentive stock option within the
meaning of section 422 of the Internal Revenue Code of 1986, as amended from
time to time (the "Code"), and is granted as of the date specified above and
expires, unless sooner terminated, at 5:00 p.m., Boulder, Colorado time, October
31, 2004.

2.  This Certificate is issued as evidence of the Option granted the Holder
pursuant to the Company's 1996 Stock Option Plan effective November 19, 1996
(the "Plan").  Subject to the express terms of this Option, the Option is
subject to all terms and conditions of the Plan, which provisions are
incorporated herein by reference.  Capitalized terms used herein and not
otherwise defined shall have the meaning assigned to them in the Plan.  A copy
of the Plan is available on request from the Company.

3.  The Option shall become exercisable as follows; 23,529 shares on the date 
hereof and an additional 23,529 on each of October 15, 1998, 1999 and 2000.

4.  In the event that any of the following occurs prior to October 15, 2000, all
shares of the Option shall vest on the date of such event, provided the
continuous employment requirement set forth in the Plan is satisfied: (i) there
occurs a greater than 40% change in ownership of the outstanding capital stock
of the Company, other than a transfer of such capital stock to a successor
entity that is a related party or affiliate of the Company or to the beneficial
owners of the current stockholders, or (ii) the Company consummates an
underwritten initial public offering.

5.  Notwithstanding the terms of Section 6.3(d)(ii) and (iii) of the Plan, if
Holder's employment by the Company is terminated because the Holder becomes
Disabled within the Option Period, or because Holder dies within the Option
Period, while employed by the Company or within the three-month period referred
to in Section 6.3(d)(iv), the Option may be exercised by Holder or those
entitled to do so under his will or by the laws of descent and distribution
within three years following his death or disability (if otherwise within the
Option Period) but not thereafter.

6.  Except as explicitly set forth in this Certificate, under the provisions of
the Plan or as the Board of Directors may determine in its sole and absolute
discretion, the Option shall not be exercisable as to any shares as to which the
continuous employment requirement is not satisfied, regardless of the
circumstances under which the Holder's employment by the Company is terminated.
The number of shares as to which the Option may be exercised is cumulative, so
that once the Option is exercisable as to any shares it shall continue to be
exercisable as to such shares until expiration or termination of the Option as
provided in the Plan.  A form of written notice for the purpose of exercising
the Option is attached.  Pursuant to the Plan, 

                                      A-1

exercising the Option is attached. Pursuant to the Plan, the Company may require
the Holder to execute a Shareholders' Agreement in connection with exercise of 
the Option.

2.  This Certificate is issued as evidence of the Option granted the Holder
pursuant to the Company's 1996 Stock Option Plan effective November 19, 1996
(the "Plan").  Subject to the express terms of this Option, the Option is
subject to all terms and conditions of the Plan, which provisions are
incorporated herein by reference.  Capitalized terms used herein and not
otherwise defined shall have the meaning assigned to them in the Plan.  A copy
of the Plan is available on request from the Company.

3.  The Option shall become exercisable as follows; 51,961 shares on each of 
October 15, 1998 and 1999, and 51,962 shares on October 15, 2000.

4.  In the event that any of the following occurs prior to October 15, 2000, all
shares of the Option shall vest on the date of such event, provided the
continuous employment requirement set forth in the Plan is satisfied: (i) there
occurs a greater than 40% change in ownership of the outstanding capital stock
of the Company, other than a transfer of such capital stock to a successor
entity that is a related party or affiliate of the Company or to the beneficial
owners of the current stockholders, or (ii) the Company consummates an
underwritten initial public offering.

5.  Notwithstanding the terms of Section 6.3(d)(ii) and (iii) of the Plan, if
Holder's employment by the Company is terminated because the Holder becomes
Disabled within the Option Period, or because Holder dies within the Option
Period, while employed by the Company or within the three-month period referred
to in Section 6.3(d)(iv), the Option may be exercised by Holder or those
entitled to do so under his will or by the laws of descent and distribution
within three years following his death or disability (if otherwise within the
Option Period) but not thereafter.

6.  Except as explicitly set forth in this Certificate, under the provisions of
the Plan or as the Board of Directors may determine in its sole and absolute
discretion, the Option shall not be exercisable as to any shares as to which the
continuous employment requirement is not satisfied, regardless of the
circumstances under which the Holder's employment by the Company is terminated.
The number of shares as to which the Option may be exercised is cumulative, so
that once the Option is exercisable as to any shares it shall continue to be
exercisable as to such shares until expiration or termination of the Option as
provided in the Plan.  A form of written notice for the purpose of

                    SEPARATION AGREEMENT AND LEGAL RELEASE

     This agreement is between Colorado Greenhouse Holdings, Inc. ("CG"), and
Edward J. Wetherbee ("Wetherbee"), and shall be effective as of October 20, 1997
(the "Effective Date").

                                   RECITALS
                                   --------

     1.   Wetherbee is employed by CG as its chief executive officer, but
desires to resign as chief executive officer as of the Effective Date.

     2.   CG and Wetherbee are parties to that certain Severance and Noncompete
Agreement (the "Agreement") dated effective as of December 31, 1996.  CG and
Wetherbee desire fully and completely to resolve all matters between them
relating in any way to Wetherbee's resignation and the Agreement.

                                   AGREEMENT
                                   ---------

     In consideration of the conditions, covenants, and agreements set forth
below, the receipt and sufficiency of which are hereby acknowledged by CG and
Wetherbee, the parties agree as follows:

     1.   Duties.  Between the Effective Date and December 31, 1997, Wetherbee
          ------                                                              
shall continue to perform the non-operating duties of Chairman of the Board (the
"Board") and shall perform such tasks as he and the Board may mutually agree.

     2.   Compensation and Benefits.
          ------------------------- 

          a.   Between the Effective Date and December 31, 1997, Wetherbee shall
remain on CG's payroll and shall continue to receive the same base salary that
he received for the pay period immediately preceding the Effective Date, payable
in installments on CG's customary paydays, less legally required withholdings.
Wetherbee shall be deemed an employee of CG until December 31, 1997, at which
time his employment with CG shall terminate.

          b.   Between the Effective Date and December 31, 1997, Wetherbee
shall be eligible to continue to participate in CG's company-sponsored benefit
plans, including its health insurance plan and its 401k plan, on the same terms
as applied to him immediately before the Effective Date.  After the effective
date, however, Wetherbee shall not accrue any paid vacation, sick days or other
paid leave of any kind.

     3.   Stock Options.  The parties acknowledge that Wetherbee currently holds
          -------------                                                         
certain unvested stock options, consisting of the option to buy 202,725 shares
of CG stock at a strike price of $.74 per share, two-thirds of which are fully
vested and one-third of which is not scheduled to vest until December 31, 1997.
In order to remove any ambiguity concerning the vesting of the final one-third
of such options, CG agrees that on the Effective Date, the last one-third of the
stock options that are scheduled to vest in Wetherbee on December 31, 1997 shall
instead vest in Wetherbee immediately.  CG further agrees to amend Wetherbee's
<PAGE>
 
existing option agreement to extend the exercise period as set forth on Exhibit 
A attached hereto and made a part hereof.

     4.   Agreement; Payments. CG and Wetherbee acknowledge and agree that the 
          -------------------
Agreement will terminate according to its terms on December 31, 1997. As final 
payment of all amounts owned to Wetherbee thereunder, CG agrees to pay and 
Wetherbee agrees to accept the payment of $120,000 as follows: $40,000 shall be 
paid on January 2, 1998 and $6666.66 shall be paid monthly for 12 months on the 
last day of each month beginning January 31, 1998 with the last payment on 
December 31, 1998.
 
     5.   Release by Wetherbee. Wetherbee, for himself and his heirs, personal 
          --------------------
representatives and assigns, and any other firm or entity that could or might 
act on behalf of him including, without limitation, his attorneys (all of whom 
are collectively referred to as "Releasors"), hereby fully and forever release 
and discharge CG, its present and future affiliates and subsidiaries, and each 
of their past, present, and future officers, directors, employees, shareholders,
independent contractors, attorneys, insurers and any and all other persons or 
entities that are now or may become liable to any Releasor due to any Releasee's
act or omission, all of whom are collectively referred to as "Releasees", of and
from any and all actions, causes of action, claims, demands, costs and expenses,
including attorneys' fees, of every kind and nature whatsoever, in law or in
equity, whether now known or unknown, that Releasors, or any person acting under
any of them, may now have, or claim at any future time to have, based in whole
or in part upon any act or omission occurring prior to the Effective Date,
without regard to present actual knowledge of such acts or omissions, including
specifically, but not by way of limitation, matters which may arise at common
law, such as breach of contract, express or implied, promissory estoppel,
wrongful discharge, tortious interference with contractual rights, infliction of
emotional distress, defamation, or under federal, state or local laws, such as
the Fair Labor Standards Act, the Employee Retirement Income Security Act, the
National Labor Relations Act, Title VII of the Civil Rights Act of 1964, the Age
Discrimination in Employment Act, the Rehabilitation Act of 1973, the Equal Pay
Act, the Americans with Disabilities Act, and the Colorado Civil Rights Act;
EXCEPT for the rights and obligations created by this agreement. Wetherbee
understands and agrees that by signing this agreement he is giving up his right
to bring any legal claim against CG of any nature related in any way, directly
or indirectly, to Wetherbee's employment relationship with CG, including his
separation from employment. Wetherbee agrees that this paragraph is intended to
be interpreted in the broadest possible manner in favor of CG, to include all
actual or potential legal claims that Wetherbee may have against CG, except as
specifically provided otherwise in this agreement.

     6.   Release by CG. CG, for itself and its affiliates, hereby fully and 
          -------------
forever releases and discharges Wetherbee of and from any and all actions,
causes of action, claims, demands, costs and expenses, including attorneys'
fees, of every kind and nature whatsoever, in law or in equity, whether now
known or unknown, that CG, or any person acting under it, may now have, or claim
at any time to have, based in whole or in part upon any act or omission
occurring prior to the Effective Date, without regard to present actual
knowledge of such acts or omissions, including specifically, but not by way of
limitation, matters which arise at common law, such as breach of contract,
express or implied, promissory estoppel, wrongful discharge, tortious
interference with contractual rights, infliction of emotional distress,
defamation or under federal, state or local laws.

     7.  Authority and Nonassignment. The parties warrant that each has 
         ---------------------------
authority to enter into this agreement, and that neither has transferred to any 
other person or entity any claim, action, demand, or cause of action released by
this agreement.

     8.  Survival of Covenants and Warranties. All covenants and warranties 
         ------------------------------------
contained in this agreement are contractual and shall survive the closing of 
this agreement.

     9.  Miscellaneous. (a) Successors and Assigns. This agreement shall be 
         -------------
binding in all respects upon, and shall inure to the benefit of, the parties' 
heirs, successors and assigns. (b) Governing Law. This agreement shall be 
governed by the law of the State of Colorado, irrespective of the choice of law 
principles of any jurisdiction. (c) Severability. In the event that a court of 
competent jurisdiction enters a final judgement holding invalid any material

enforceable. (d) Integration. This agreement and the Agreement constitute the

agreements. (e) Modification. This agreement and the Agreement shall not be 
modified except in a writing signed by the parties. (f) Waiver. No term or 
condition of this agreement shall be deemed to have been waived, nor shall there
be an estoppel against the enforcement of any provision of this agreement except
by written instruments signed by the party charged with the waiver or estoppel. 
No waiver shall be deemed a continuing waiver unless specifically stated 
therein, and the written waiver shall operate only as to the specific term or 
condition waived, and not for the future or as to any act other than that 
specifically waived. (g) Headings. Paragraph headings are intended solely as a 
convenience and shall not control the meaning or interpretation of any provision
of this agreement. (h) Gender and Number. Pronouns contained in this agreement 
shall equally apply to the feminine, neuter, and masculine genders. The singular

acknowledge that they have reviewed this agreement in its entirety and have had 
a full opportunity to negotiate its terms, and therefore waive all applicable
