in its entirety by the more detailed information and financial statements
(including the notes thereto) appearing elsewhere in this Prospectus. Unless
otherwise indicated, all share, per share and financial information set forth
herein assumes a public offering price of $16.875 per share and no exercise of

the terms "Company" and "UniMark" refer to The UniMark Group, Inc., and its
consolidated subsidiaries, including UniMark Foods, Inc. ("UniMark Foods"),
UniMark International, Inc. ("UniMark International"), Industrias Citricolas de
Montemorelos, S.A. de C.V. ("ICMOSA"), Grupo Industrial Santa Engracia, S.A. de
C.V. ("GISE"), Simply Fresh Fruit, Inc. ("Simply Fresh") and Les Produits
Deli-Bon Inc. ("Deli-Bon").
 
                                  THE COMPANY
 
GENERAL
 
     UniMark is a vertically integrated citrus and tropical fruit growing,
processing, marketing and distribution company with operations in Mexico, the
United States and Canada. The UniMark Group, Inc. was organized in 1992 to
combine the operations of ICMOSA, a Mexican citrus and tropical fruit processor
which commenced operations in 1974, with UniMark Foods, a company that marketed
and distributed ICMOSA's products in the United States. The Company focuses on
niche citrus and tropical fruit products including chilled, frozen and canned
cut fruits and other specialty food ingredients. In addition, as a result of its
recent acquisition of GISE, UniMark is a major Mexican producer of citrus
concentrate, oils and juices. The Company processes and packages its products at
nine plants in Mexico, one in California and one in Quebec, Canada. The
Company's Mexican and California plants are strategically located in major fruit
growing regions. The Company utilizes food brokers and distributors to market
and distribute its cut fruit products under the brand names SUNFRESH(TM), Fruits
of Four Seasons(R) and Kledor(R) and under various private labels, to
supermarket chains, foodservice distributors, wholesale clubs, specialty grocery
stores and industrial users throughout the United States and Canada. Under the
Jalapeno Sam(R) brand name, the Company also produces guacamole for distribution
in the United States. In addition, the Company has developed and utilizes a
unique processing method that separates cold-peeled citrus fruit into individual
juice-containing "cell-sacs." These cell-sac products are sold to food and soft
drink manufacturers in Japan to enhance the flavor and texture of fruit juices
and desserts. Sales to the Company's Japanese consumers are facilitated through
Japanese trading companies. The Company's citrus concentrate and individual
strength citrus juices are sold directly to major juice importers and
distributors in North America, Europe and Japan.
 
     The Company has experienced substantial increases in net sales and income
from operations over the past three fiscal years. UniMark's net sales were
$18,893,000, $25,346,000 and $36,866,000, respectively, in its 1993, 1994 and
1995 fiscal years, representing a compound annual growth rate of 39.7% over such
periods. Furthermore, UniMark's income from operations was $633,000, $1,530,000
and $4,251,000, respectively, in such fiscal years, representing a compound
annual growth rate of 159.1% over such periods.
 
STRATEGY
 
     UniMark's strategic objective is to become the leading
vertically-integrated grower, processor, marketer and distributor of niche fruit
and other selected agricultural products. To achieve this objective, the key
elements of the Company's operating strategy are as follows: (i) expand vertical
integration of growing, processing, marketing and distribution operations; (ii)
expand fruit growing operations in Mexico; (iii) capitalize on the SUNFRESH(TM)
brand awareness and market penetration; (iv) introduce additional cut fruit
products utilizing a cryogenic individual quick freeze ("IQF") process; (v)
continue expansion of exports to the Japanese market; (vi) continue expansion of
specialty food ingredients; and (vii) expand its position as a leading Mexican
juice exporter to the North American, European and Asian markets. In addition,
UniMark has formulated an acquisition strategy that targets (i) productive
assets in Mexico that can benefit from UniMark's international distribution and
marketing expertise, and (ii) food processing companies that possess favorable
operating or distribution synergies.

juices (the "GISE Acquisition") in exchange for 782,614 shares of Common Stock
and up to an additional $8.0 million of contingent consideration if certain
future earnings targets are achieved. GISE's two juice plants are located in Cd.
Victoria, Tamaulipas, Mexico and Poza Rica, Veracruz, Mexico in the heart of
major citrus growing regions. UniMark believes that the GISE Acquisition will
confer operational benefits on both companies resulting from combining fruit
procurement functions. In addition, UniMark believes that GISE should benefit
from UniMark's international distribution and marketing expertise. Further, the
GISE Acquisition significantly increases the Company's production capacity of
citrus oils.
 
     Simply Fresh.  In May 1996, the Company acquired all of the outstanding
shares of capital stock of Simply Fresh, a fruit processing and distribution
company located in Los Angeles, California (the "Simply Fresh Acquisition"), in
exchange for $2.5 million in cash, 90,909 shares of Common Stock and $1.0
million in cash payable in consideration for a five-year covenant by Simply
Fresh's principals and their affiliates not to compete in the United States.
Substantially all of Simply Fresh's sales are to the foodservice industry in the
western United States. UniMark believes that the Simply Fresh Acquisition will
afford it with operational synergies resulting from processing some of the fruit
used in Simply Fresh's products at UniMark's Mexican plants and expanded
distribution into the foodservice market. In addition, the Simply Fresh plant is
strategically located to process fruit grown in California and Arizona, two
major citrus growing regions with growing seasons that are generally opposite to
those of Mexico.
 
     Deli-Bon.  In January 1996, the Company acquired all of the outstanding
shares of capital stock of Deli-Bon (the "Deli-Bon Acquisition") for $787,000 in
cash, a $49,000 promissory note and 28,510 shares of Common Stock. Deli-Bon
processes primarily fruit salad at its processing plant in Quebec, Canada for
distribution to the retail and foodservice markets of Canada and the
northeastern United States. UniMark believes that it will enjoy significant
synergistic benefits from integrating UniMark and Deli-Bon's fruit procurement,
processing and distribution functions. In addition, the Company believes that
the Deli-Bon plant is strategically located to distribute products to the retail
and foodservice markets in Canada and in the northeastern United States.
 
     The Company was incorporated in January 1992 under the laws of the State of
Texas. The Company's corporate headquarters are located at 124 McMakin Road,
Lewisville, Texas 75067 and its telephone number is (817) 491-2992.

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
 
     The discussion in this Prospectus contains forward-looking statements that
involve risks and uncertainties. The Company's actual results could differ
significantly from those discussed herein. Factors that could cause or
contribute to such differences include, but are not limited to, those discussed
in "Risk Factors," "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and "Business," as well as those discussed elsewhere
in this Prospectus. Statements contained in this Prospectus that are not
historical facts are forward-looking statements that are subject to the safe
harbor created by the Private Securities Litigation Reform Act of 1995. A number
of important factors could cause the Company's actual results for 1996 and
beyond to differ materially from those expressed in any forward-looking
statements made by, or on behalf of, the Company. These factors include, without
limitation, those listed below in "Risk Factors."
 
                                  RISK FACTORS
 
     In evaluating an investment in the Common Stock being offered hereby,
investors should consider carefully, among other things, the following risk
factors, as well as the other information contained in this Prospectus.
 
RISKS RELATED TO THE COMPANY
 
  Growth and Integration of Acquisitions
 
     The expansion of the Company's operations, whether through acquisitions or
internal growth, may place substantial burdens on the Company's management
resources and financial controls. There is no assurance that the increasing
burdens on the Company's managerial resources and financial controls will not
have an adverse effect on the Company's operations. One of the Company's
strategies is to increase its revenues and the markets it serves through the
acquisition of other businesses that complement the Company's fruit processing
capabilities, channels of distribution and marketing expertise. Although the
Company has recently completed three acquisitions, there can be no assurance
that the Company will be able to identify, acquire or profitably manage
additional companies or successfully integrate recent or future acquisitions
into its operations without substantial costs, delays or other problems. In
addition, there can be no assurance that any companies acquired will be
profitable at the time of their acquisition or will achieve sales and
profitability that justify the investment therein. Acquisitions may involve a
number of special risks, including adverse effects on the Company's reported
operating results, diversion of management's attention, dependence on retention
and hiring of key personnel, risks associated with unanticipated problems or
legal liabilities and amortization of acquired intangible assets, some or all of
which could have a material adverse effect on the Company's operations and
financial performance. See "Use of Proceeds" and "Business -- Strategy."
 
  Uncertainty of New Product Development and Market Acceptance of New Products
 
     In addition to its existing product lines, the Company is currently engaged
in various stages of product development. The Company is actively engaged in the
development and commercialization of new products, such as chilled fruit snacks
and IQF citrus and tropical fruit. Continued product development and
commercialization efforts are subject to all of the risks inherent in the
development of new products, including unanticipated development problems, as
well as the possible insufficiency of funds to undertake development and
commercialization that could result in abandonment or substantial change in the
development of a specific product. In addition, demand and market acceptance for
newly developed products are subject to a high level of uncertainty. The Company
has not yet commenced significant marketing activities relating to
commercialization of its new products and has only conducted limited market or
feasibility studies for any of such products. Achieving market acceptance for
the Company's new products will require substantial marketing efforts and the
expenditure of significant funds. The Company's prospects will be significantly
affected by its ability to commercialize its new products. See "Business -- New
Products."
 
                                        6
<PAGE>   9
 
  Dependence Upon Availability and Price of Fresh Fruit
 
     The Company obtains a substantial amount of its raw materials from
third-party suppliers throughout various growing regions in Mexico, Texas and
California. A crop reduction or failure in any of these fruit growing regions
resulting from factors such as weather, pestilence, disease or other natural
disasters, could increase the cost of the Company's raw materials or otherwise
adversely affect the Company's operations. Competitors may be affected
differently depending upon their ability to obtain adequate supplies from
sources in other geographic areas. If the Company is unable to pass along the
increased raw materials cost, the financial condition and results of operations
of the Company could be materially and adversely affected. See
"Business -- Procurement."
 
  Competition
 
     The food and beverage industry, including each of the markets in which the
Company competes, is highly competitive with respect to price and quality
(including taste, texture, healthfulness and nutritional value). The Company
faces potential competition from numerous, well-established competitors
possessing substantially greater financial, marketing, personnel and other
resources than the Company. In addition, the food and beverage industry is
characterized by frequent introductions of new products, accompanied by
substantial promotional campaigns. In recent years, numerous companies have
introduced products, including products positioned to capitalize on growing
consumer preferences for fresh fruit products. It can be expected that the
Company will be subject to increasing competition from companies whose products
or marketing strategies address these consumer preferences. See
"Business -- Competition."
 
  Dependence on Significant Customers
 
     During 1993, 1994 and 1995, indirect sales to Sam's Wholesale Clubs
accounted for approximately 17.5%, 18.5% and 17.6%, respectively, of the
Company's net sales (without giving pro forma effect to the Acquisitions).
During 1993, 1994 and 1995, sales to the Company's Japanese customers, through
Mitsui Foods, Inc., a Japanese trading company, accounted for approximately
10.7%, 19.5% and 27.5%, respectively, of the Company's net sales (without giving
pro forma effect to the Acquisitions). 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. Consistent with industry practice, the
Company does not operate under a long-term written supply contract with any of
its customers. The Company's business could be materially adversely affected by
the loss of these or any other major customer. See "Business -- Marketing, Sales
and Distribution."
 
  Seasonality and Quarterly Fluctuations
 
     The Company's operations and sales are affected by the growing cycle of the
fruits it processes. Because of seasonal fluctuations, there can be no assurance
that the results of any particular quarter will be indicative of results for the
full year of operations. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
  Product Liability and Product Recall
 
     The testing, marketing, distribution and sale of food and beverage products
entails an inherent risk of product liability and product recall. There can be
no assurance that product liability claims will not be asserted against the
Company or that the Company will not be obligated to recall its products.
Although the Company maintains product liability insurance coverage, there can
be no assurance that an adequate level of coverage is presently in place or will
be available in the future. A product recall or a partially or completely
uninsured judgment against the Company could have a material adverse effect on
the Company.
 
  Limited Intellectual Property Protection
 
     The Company regards its trademarks, trade dress, trade secrets and similar
intellectual property as important to its success. The Company has been issued a
registered trademark for its Fruits of Four Seasons(R), Jalapeno Sam(R), Fruit
Made Easy(R) and Kledor(R) trademarks. The Company has filed for trademark
protection
 
                                        7
<PAGE>   10
 
for its SUNFRESH(TM) trademark. No assurance can be given that the Company will
be successful in obtaining such trademark protection, that the Company will not
face future legal challenges with respect to its use of such trademarks or that
the trademarks will afford the Company with any competitive advantages.
 
  Government Regulation
 
     The manufacture, processing, packaging, storage, distribution and labeling
of food products is 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 (the "FDA") and the United States
Department of Agriculture. Applicable statutes and regulations governing food
products include "standards of identity" for the content of specific types of
foods, nutritional labeling and serving size requirements and "Good
Manufacturing Practices" with respect to production processes. The Company
believes that its current products satisfy, and its new products will satisfy,
all applicable regulations and that all of the ingredients used in its products
are "Generally Recognized as Safe" by the FDA for the intended purposes for
which they will be used. Failure to comply with applicable laws and regulations
could subject the Company to civil remedies, including fines, injunctions,
recalls or seizures, as well as potential criminal sanctions, which could have a
material adverse effect on the Company.
 
     The operations of UniMark in Mexico are subject to Mexican federal and
state laws and regulations relating to the protection of the environment. The
principal legislation is the federal General Law of Ecological Balance and
Environmental Protection (the "Ecological Law"), which is enforced by the
Ministry of Social Development ("Sedesol"). Under the Ecological Law, rules have
been promulgated concerning water pollution, air pollution, noise pollution and
hazardous substances. Sedesol can bring administrative and criminal proceedings
against companies that violate these environmental laws, and can also close non-
complying facilities. The operations of UniMark in Canada are subject to
Canadian federal and provincial laws and regulations relating to the protection
of the environment including An Act Respecting Occupational Health and Safety
(Quebec), the Canadian Environmental Protection Act (Canada), and the
Environment Quality Act (Quebec). Similarly, the operations of UniMark in the
United States are subject to United States federal and state laws and
regulations relating to the protection of the environment. Although the Company
believes that its facilities currently are in compliance with all applicable
environmental laws, failure to comply with any such laws could have a material
adverse effect on the Company. See "Business -- Government Regulations."
 
  Dependence on Key Management
 
     The Company relies on the business and technical expertise of its executive
officers and certain other key employees, particularly its President and Chief
Executive Officer, Jorn Budde; its Executive Vice President and Chief Operating
Officer, Rafael Vaquero Bazan; and the President and Chief Executive Officer of
GISE, Jose Martinez Brohez. The loss of the services of any one of these
individuals could have a material adverse effect on the Company. The employment
agreements with each of Messrs. Budde and Vaquero have recently expired.
Although the Company's Board of Directors has indicated its intention to enter
into new employment contracts with each of Messrs. Budde and Vaquero, no
assurance can be given that their services or those of Mr. Martinez will be
available in the future. The Company's success will also be dependent on its
ability to attract and retain other qualified personnel. See
"Business -- Employees" and "Management."
 
  Shares Eligible for Future Sale; Potential Adverse Effect on Market Price of
Common Stock
 
     Sales of shares of Common Stock in the public market, including "restricted
shares" first becoming eligible for resale following this offering, could
adversely affect prevailing market prices. As of May 10, 1996, there were
outstanding 6,861,833 shares of Common Stock, 2,541,951 of which shares were
"restricted securities" under applicable securities laws. Additional shares of
Common Stock may become eligible for sale in the public market from time to time
upon exercise of warrants and stock options. See "Description of Capital
Stock -- Shares Eligible for Future Sale."
 
                                        8
<PAGE>   11
 
  Control by Management
 
     Following the completion of this offering, the current directors and
officers of the Company and their affiliates will own approximately 37.1% of the
outstanding shares of Common Stock. As a result of such persons' Common Stock
ownership, they will have significant influence over all matters requiring
approval by the shareholders of the Company, including the election of
directors. See "Management" and "Principal and Selling Shareholders."
 
RISKS RELATED TO MEXICAN OPERATIONS
 
  Economic, Political and Social Conditions
 
     Although a majority of the Company's processing operations and
substantially all of its growing operations are located in Mexico, substantially
all of the Company's sales are to customers outside of Mexico, mostly in the
United States, Japan, Canada and Europe.
 
     Due to the location of its growing operations and processing facilities,
the Company may be affected by economic, political and social conditions in
Mexico. For example, the Company's financial condition and results of operations
or the market price of its Common Stock could be adversely affected if the
current Mexican policies encouraging foreign investment and foreign trade by
Mexico were to be reversed. In addition, the attractiveness of the Company's
products to its North American and Japanese customers is affected by U.S.,
Canadian, Japanese and Mexican trade policies, such as trade preferences.
Changes in policies by the U.S., Mexican, Canadian, Japanese, European Economic
Community or other governments resulting in, among other things, increased
duties, higher taxation, currency conversion limitations, limitations on imports
or exports or the expropriation of private enterprises could have a material
adverse effect on the Company's results of operations. Furthermore, Mexico has
experienced political, economic and social uncertainty resulting from the
assassination of two prominent political leaders in 1994 and a peasant uprising
in the southern Mexican state of Chiapas.
 
     Since December 1994, Mexico has experienced an economic crisis
characterized by exchange rate instability and 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 such policies, that such policies will be
successful if pursued, or that such policies will not be significantly altered.
 
  Exchange Rates and Inflation
 
     While the Company transacts business in U.S. dollars and its revenues are
collected in U.S. dollars, a portion of the Company's costs and expenses are not
denominated in U.S. dollars; substantially all of such non-U.S. dollar
denominated costs and expenses are denominated in Mexican pesos ("pesos"). As a
result, changes in the relationship of the U.S. dollar to the peso could
adversely affect the Company's cost of goods sold, operating expenses and
operating margins. The devaluation of the peso during late 1994 and early 1995
reduced the U.S. dollar cost of the Company's peso expenses. From December 18,
1994 through October 1, 1995, the U.S. dollar appreciated approximately 84% in
value against the peso. In addition, inflation in the peso could affect the
Company's cost of goods sold and operating margins. Mexican inflation, as
measured by the NCPI, the Mexican government's consumer price index, was 8.35%
for the three months ended March 31, 1996, and was 52% for 1995. Inflation in
Mexico may ultimately increase the cost of goods and services purchased in
Mexico with pesos and lead to higher wages and salaries for the Company's
employees. Such increases may adversely affect the Company's operating margins
in the future. The impact of future exchange rate fluctuations and inflation on
the Company's results of operations cannot be accurately predicted.
 
     On October 29, 1995, the Mexican government signed a pact with labor and
business representatives called the Alliance for Economic Recovery (the
"Alliance"). The Alliance defines a macroeconomic policy designed to support
Mexico's economic recovery and promote future growth. By its provisions, the
minimum
 
                                        9
<PAGE>   12
 
wage rate increased by 10% effective December 4, 1995. A further 10% rise in the
minimum wage rate became effective on April 1, 1996. Also, over the 14 months
following execution of the Alliance, utility charges will increase an average of
26%. Under the Alliance, the Mexican government will attempt to boost the
economy by providing tax incentives for new business investments, while
utilizing wage and price controls to contain inflation. As part of the Alliance,
the Mexican government has committed to maintaining a free flotation system for
the peso in the international currency markets. The Alliance also calls for
development of social and rural programs. The impact of the Alliance on the
Company or the Mexican economy cannot be accurately predicted.
 
     Although from time to time the Company has engaged in exchange rate hedging
activities, the Company does not have a program for hedging U.S. dollar/peso
revenues or costs. There can be no assurance that any hedging techniques will be
successful and will not result in exchange losses. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
  Labor Relations and Labor Cost
 
     In Mexico, labor relations are governed by separate collective labor
agreements between ICMOSA and GISE and the unions representing their employees.
Substantially all of the Company's Mexican employees, whether seasonal or
permanent, are affiliated with labor unions which are generally affiliated with
a national confederation. As is typical in Mexico, wages are renegotiated every
year while other terms are renegotiated every two years. In the event
labor-related work stoppages were to occur or employee wages were renegotiated
on terms adverse to the Company, such events could have an adverse effect on the
Company.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 1,400,000 shares of
Common Stock offered by the Company are estimated to be approximately $21.7
million after deducting underwriting discounts and estimated offering expenses.
The Company will not receive any of the proceeds from the sale of the shares
offered by the Selling Shareholders.
 
     The following table sets forth the anticipated uses of the net proceeds
from this offering:

(1) Of this amount, $2.5 million was used to fund the cash portion of the
    consideration paid in connection with the Simply Fresh Acquisition. The
    interest rate on this $3.0 million 120-day bank loan is 11.37% per annum and
    it matures in September 1996.
 
(2) Represents the Company's planned exercise of an option to purchase GISE's
    leased facility located in Poza Rica, Veracruz, Mexico.
 
     The exact allocation of the proceeds for such purposes and the timing of
such expenditures may vary significantly depending upon numerous factors,
including the success of the Company's products under development. Pending the
application of such proceeds, the Company intends to invest the net proceeds of
this offering in short-term, investment grade securities. The Company estimates
that such proceeds will be sufficient to fund such expenditures and other cash
requirements for at least the next 12 months. However, the time periods during
which the proceeds will be invested in such securities may vary significantly
depending upon a number of factors, and no assurances can be given in this
regard. Although the Company has no present commitments, agreements or
understandings with respect to any acquisitions, the Company may use a portion
of the net proceeds to continue its acquisition strategy. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                              RECENT ACQUISITIONS
 
     Since January 1, 1996, the Company has completed the following three
acquisitions. For additional information concerning these businesses, see
"Business."
 
THE GISE ACQUISITION
 
     In May 1996, the Company acquired all of the outstanding shares of capital
stock of GISE, a major Mexican producer of citrus concentrate, oils and juices,
in exchange for 782,614 shares of Common Stock. In addition, UniMark agreed to
pay to the GISE stockholders up to an additional $8.0 million of contingent
consideration if certain future earnings targets are achieved. The stock
purchase agreement with the GISE stockholders (the "GISE Agreement") provides
that if for any of 1996, 1997, 1998 or 1999 (a) GISE's income before interest,
depreciation, amortization, taxes and translation gain/loss ("EBITDA") less Cost
of Capital (as defined below) exceeds (b) the Target Base EBITDA Amounts (as set
forth in the table below) for the corresponding year (as set forth in the table
below), then, UniMark shall pay to the GISE stockholders an amount equal to 3.5
times such excess amount (the "Additional Consideration") up to a cumulative
aggregate amount of $8.0 million:

           1998..........................................................     7,517,000
           1999..........................................................     9,542,000
</TABLE>
 
     The GISE Agreement provides that "Cost of Capital" for any fiscal year
shall mean an amount equal to 10% of Outstanding Cumulative Capital
Expenditures. "Outstanding Cumulative Capital Expenditures" for a particular
fiscal year is defined as (a) the weighted average amount of all expenditures
made by GISE during the particular fiscal year for assets with an expected life
in excess of one year plus (b) the amount of all expenditures for assets with an
expected life in excess of one year made by GISE after May 9, 1996 but prior to
the beginning of that particular fiscal year. Additional Consideration, if any,
that may be due with respect to any year shall be due and payable on April 1 of
the following year, at UniMark's option in either shares of Common Stock or
cash.
 
     GISE's two juice plants are located in Cd. Victoria, Tamaulipas, Mexico and
Poza Rica, Veracruz, Mexico in the heart of major citrus growing regions.
UniMark believes that the GISE Acquisition will confer operational benefits on
both companies resulting from combining fruit procurement functions. In
addition, UniMark believes that GISE should benefit from UniMark's international
distribution and marketing expertise.
 
THE SIMPLY FRESH ACQUISITION
 
     In May 1996, the Company acquired all of the outstanding shares of capital
stock of Simply Fresh, a fruit processing and distribution company located in
Los Angeles, California. The purchase price for the shares consisted of $2.5
million in cash, 90,909 shares of Common Stock and $1.0 million in cash payable
in consideration for a five-year covenant by Simply Fresh's principals and their
affiliates not to compete in the United States. In addition, the Company has
agreed to pay Simply Fresh's two stockholders an amount equal to $0.0025 per
pound of fruit processed using certain proprietary technology developed by
Simply Fresh with the amount payable pursuant to this agreement not to exceed
$2.0 million in the aggregate.
 
     Substantially all of Simply Fresh's sales are to the foodservice industry
in the western United States. UniMark believes that the Simply Fresh Acquisition
will afford it with operating synergies resulting from processing some of the
fruit used in Simply Fresh's products at UniMark's Mexican plants and expanded
distribution into the foodservice market. In addition, the Simply Fresh plant is
strategically located to process fruit grown in California and Arizona, two
major citrus growing regions with growing seasons that are generally opposite to
those of Mexico.

THE DELI-BON ACQUISITION
 
     In January 1996, the Company acquired all of the outstanding shares of
capital stock of Deli-Bon for $787,000 in cash, a $49,000 promissory note and
28,510 shares of Common Stock.
 
     Deli-Bon, located in Quebec City, Canada, processes and sells fruit salads
principally to the foodservice industry and wholesale clubs in Canada and the
northeastern United States. UniMark believes that it will realize significant
operating synergies from integrating its and Deli-Bon's fruit procurement,
processing and distribution functions. In addition, the Company believes that
the Deli-Bon plant is strategically located to distribute products to the retail
and foodservice markets in Canada and in the northeastern United States.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
INTRODUCTION
 
     The following discussion should be read in conjunction with the
consolidated financial statements and notes thereto and "Selected Consolidated
Financial Data" included elsewhere in this Prospectus. This discussion does not
include the results of operations of Deli-Bon, GISE and Simply Fresh, which were
acquired after December 31, 1995.
 
CONVERSION FROM MEXICAN GAAP
 
     The Company conducts substantially all of its operations through its
wholly-owned operating subsidiaries: UniMark Foods, UniMark International,
ICMOSA, GISE, Simply Fresh and Deli-Bon. ICMOSA is a Mexican corporation with
its headquarters located in Montemorelos, Nuevo Leon, Mexico, whose principal
activities consist of operating six citrus processing plants and various citrus

  Years Ended December 31, 1994 and 1995
 
     Net sales increased 45.5% from $25.3 million in 1994 to $36.9 million in
1995. This increase was due primarily to a 102.4% increase in export sales to
Japan from $6.0 million in 1994 to $12.1 million in 1995. The increase in sales
to Japan resulted primarily from an expansion of UniMark's Japanese customer
base and product lines. In addition, North American retail sales increased 25.9%
from $10.0 million in 1994 to $12.5 million in 1995 and wholesale club sales
increased 39.2% from $5.1 million in 1994 to $7.1 million in 1995. These
increases resulted from, among other things, increased distribution of existing
products, the success of its red grapefruit products and the introduction of a
one gallon mixed fruit product to the wholesale club market in 1995.
 
                                       16
<PAGE>   19
 
     Gross profit as a percentage of net sales increased from 29.2% in 1994 to
34.4% in 1995. This increase resulted from reduced processing costs obtained
through greater efficiencies and volume. In addition, prices of certain products
sold to Japan were increased during 1995 and import duties between Mexico and
the U.S. decreased as a result of the North American Free Trade Agreement
("NAFTA").
 
     Selling, general and administrative expenses ("SG&A") as a percentage of
net sales decreased from 23.2% in 1994 to 22.9% in 1995. This reduction is
primarily the result of the increased sales volume in 1995. Actual SG&A expenses
increased $2.5 million from $5.9 million in 1994 to $8.4 million in 1995. This
increase resulted from increased delivery, storage and personnel expenses
required to handle the increased sales volume.
 
     Interest expense decreased from 1.9% of net sales in 1994 to 0.9% in 1995.
Actual interest expense decreased $151,000 from $469,000 in 1994 to $318,000 in
1995. This decrease was primarily the result of lower levels of debt and lower
interest rates in 1995.
 
     Interest income of $470,000 was earned in 1995 primarily from the temporary
cash investment of proceeds from the exercise of warrants and excess cash
balances generated from operations.
 
     Other income, net of other expenses was $69,000 in 1994 and $222,000 in
1995. Included in this net total is a foreign currency transaction loss of
$16,000 in 1994 and a gain of $124,000 in 1995 resulting from the conversion of
ICMOSA's Mexican financial statements to U.S. GAAP.
 
     Net income, as a result of the foregoing, increased 190% from $1.0 million
in 1994 to $2.9 million in 1995.
 
  Years Ended December 31, 1993 and 1994
 
     Net sales increased 34.2% from $18.9 million in 1993 to $25.3 million in
1994. This increase was due in part to a 78.4% increase in export sales to Japan
from $3.4 million in 1993 to $6.0 million in 1994. In addition, the Company
began distributing frozen melon products in May 1994 with sales totaling $2.3
million in 1994. Net sales to wholesale clubs also increased from $4.1 million
in 1993 to $5.1 million in 1994, or 23.1%, due to increased distribution in
existing clubs and new distribution in new clubs.
 
     Gross profit as a percentage of net sales decreased from 31.5% in 1993 to
29.2% in 1994. This decrease resulted from the introduction of frozen products
at a marginal gross profit in 1994. Excluding frozen products sales and profits,
gross profit as a percentage of net sales increased to 32.0% in 1994 as a result
of decreased import duties between Mexico and the U.S. as a result of NAFTA and
a retail price increase implemented in 1994.
 
     Selling, general and administrative expenses ("SG&A") as a percentage of
net sales decreased from 28.1% in 1993 to 23.2% in 1994. This reduction is
primarily the result of the increased sales volume in 1994. Actual SG&A expenses
increased $554,000 from $5.3 million in 1993 to $5.9 million in 1994. This
increase resulted from increased delivery, storage and personnel expenses
required to handle the increased sales volume.
 
     Interest expense decreased from 2.1% of net sales in 1993 to 1.9% of net
sales in 1994. Actual interest expense increased $59,000 from $410,000 in 1993
to $469,000 in 1994. This increase was primarily the result of higher interest
rates in 1994.
 
     Other income, net of other expenses was $11,000 in 1993 and $69,000 in
1994. Included in this net total is a foreign currency transaction loss of
$8,000 in 1993 and $16,000 in 1994 resulting from the conversion of ICMOSA's
Mexican financial statements.
 
     Net income, as a result of the foregoing, increased from $73,000 in 1993 to
$1.0 million in 1994.
 
STATUTORY EMPLOYEE PROFIT SHARING
 
     All Mexican companies are required to pay their employees, in addition to
their agreed compensation benefits, profit sharing in an aggregate amount equal
to 10% of net income, calculated for employee profit sharing purposes, of the
individual corporation employing such employees. All of UniMark's employees are
 
                                       17
<PAGE>   20
 
employed by its subsidiaries, each of which pays profit sharing in accordance
with its respective net income for profit sharing purposes. Tax losses do not
affect employee profit sharing. Statutory employee profit sharing expense is
reflected in the Company's cost of goods sold and selling, general and
administrative expenses, depending upon the function of the employees to whom
profit sharing payments are made. The Company's net income on a consolidated
basis as shown in the Consolidated Financial Statements is not a meaningful
indication of net income of the Company's subsidiaries for profit sharing
purposes or of the amount of employee profit sharing.
 
EXCHANGE RATE FLUCTUATIONS
 
     The Company procures and hand processes substantially all of its products
in Mexico, through its wholly owned subsidiary ICMOSA, for export to the United
States, Canada and Japan. Generally, the cost of fruit procured in Mexico
reflects the spot market price for citrus in the United States. All of UniMark's
sales are denominated in U.S. dollars. As such, UniMark does not anticipate
sales revenues and raw material expenses to be materially affected by changes in
the valuation of the peso. Labor and certain other production costs are peso
denominated. Consequently, these costs are impacted by fluctuations in the value
of the peso relative to the U.S. dollar.
 
     The Company's consolidated results of operations are affected by changes in
the valuation of the Mexican peso to the extent that ICMOSA has peso denominated
net monetary assets or net monetary liabilities. In periods where the peso has
been devalued in relation to the U.S. dollar, a gain will be recognized to the
extent there are peso denominated net monetary liabilities while a loss will be
recognized to the extent there are peso denominated net monetary assets. In
periods where the peso has gained value, the converse would be recognized.
 
     The Company's consolidated results of operations are also subject to
fluctuations in the value of the peso as they affect the translation to U.S.
dollars of ICMOSA's net deferred tax assets or net deferred tax liabilities.
Since these assets and liabilities are peso denominated, a falling peso results
in a transaction loss to the extent there are net deferred tax assets or a
transaction gain to the extent there are net deferred tax liabilities.
 
SEASONALITY
 
     A substantial portion of UniMark's exports to Japan is processed and
shipped during the first and fourth quarter each year. In addition, the demand
for UniMark's chilled citrus and tropical fruit products is strongest during the
fall, winter and spring when seasonal fresh products such as mangos, peaches,
plums, and nectarines are not readily available for sales in supermarkets in
North America. Management believes UniMark's quarterly net sales will continue
to be impacted by this pattern of seasonality.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At December 31, 1995, cash and temporary cash investments totaled $6.3
million, an increase of $5.5 million from year end 1994. Operating activities
utilized cash of $1.5 million in 1994 while generating cash of $3.3 million in
1995. Net cash generated by operating activities in 1995, was favorably impacted
by the increase in net income and an increase in the amount payable to Sabritas,
S.A. de C.V., PepsiCo, Inc.'s Mexican snack food division, pursuant an export
trade credit facility (the "Trading Agreement"). Since 1992, UniMark has
partially financed its Mexican exports under the Trading Agreement. The Trading
Agreement provides for 60-day interest free financing up to $3,000,000 for
inventory exports from Mexico. At December 31, 1994, there were no amounts
outstanding pursuant to the Trading Agreement. At year end 1995, $2.6 million
was payable to Sabritas, S.A. de C.V. under the Trading Agreement. The Trading
Agreement can be terminated by either party with 90 days notice.
 
     During 1995, UniMark expended $5.2 million on additional facilities,
equipment and improvements to plant facilities. In October 1995, UniMark
acquired an idle canning plant in the State of Puebla, Mexico for approximately
$1.5 million. Remaining capital outlays in 1995 were for equipment, fixtures and
improvements and additions to plant facilities. During 1994, UniMark expended
$1.2 million on capital equipment and improvements to plant facilities. In
September 1994, UniMark acquired a leasehold interest in an idle citrus
 
                                       18
<PAGE>   21
 
processing facility in San Rafael, Veracruz, Mexico and purchased approximately
$700,000 of processing equipment located at the facility. Additional capital
outlays in 1994 were for expansion and improvements to the Mexico plant
facilities in Montemorelos, Nuevo Leon.
 
     Net cash generated by financing activities was $7.4 million in 1995 and
$3.2 million in 1994. Included in financing activities were net proceeds from
the issuance of stock, changes in short-term borrowings and payments of
long-term debt.
 
     Net proceeds from the issuance of shares of Common Stock was $5.2 million
in 1994 and $5.6 million in 1995. In August 1994, UniMark completed an initial
public offering of 550,000 units (the "Units"), each Unit consisting of three
shares of Common Stock and two redeemable common stock purchase warrants (the
"Warrants"). The Warrants were transferable separately from the Common Stock and
entitled the holder to purchase one share of Common Stock at an exercise price
of $4.50 per share. The Units were sold to the public at $12.00 per Unit, with
net proceeds to UniMark of approximately $5.2 million. In connection with the
Company's initial public offering, UniMark issued certain warrants to its
underwriting representatives (the "Representatives' IPO Warrants") to purchase
up to 55,000 Units for $15.00 per Unit. On June 8, 1995, UniMark notified all
registered holders of the Warrants of its intention to redeem all of the
1,100,000 outstanding Warrants by July 21, 1995. During 1995, UniMark issued (i)
1,099,990 shares of Common Stock upon the exercise of a like amount of the
Warrants; (ii) 163,060 shares of Common Stock upon the exercise of 32,612
Representatives' IPO Warrants and the 65,224 underlying Warrants; and (iii)
5,000 shares of Common Stock on the exercise of employee stock options. Net
proceeds to UniMark on the issuance of these 1,268,050 shares of Common Stock in
1995 were $5.6 million.
 
     Cash was utilized to decrease short-term borrowings by $1.5 million in 1994
while cash of $2.3 million was generated in 1995 from an increase in short-term
borrowings. During 1994, short-term debt was reduced in preparation for
consolidating and restructuring existing credit facilities in Mexico and the
United States. During 1995, UniMark established two revolving credit facilities
with Bank of America, N.A. and Rabobank for short-term debt of up to $6.0
million in Mexico and up to $3.0 million in the United States. Borrowings under
the Mexico revolving credit facility are collateralized by accounts receivable
from export sales to Japan while borrowings under the United States revolving
credit facility are collateralized by United States accounts receivable and
finished goods inventories. The Mexico revolving credit facility is reviewed
annually for renewal while the United States revolving credit facility matures
on April 30, 1997. At December 31, 1995, the Mexico revolving credit facility
had an outstanding balance of $1.5 million while the United States revolving
credit facility had an outstanding balance of $2.0 million. The $2.3 million
increase in short-term borrowings in 1995 resulted from the utilization of these
new credit facilities. In May 1996, in connection with the Simply Fresh
Acquisition, the Company borrowed $3.0 million pursuant to a 120-day bank loan
with Confia, S.A., Institucion de Banca Multiple, Abaco Casa de Bolsa, S.A. de
C.V. ("Confia"). This loan is expected to be repaid from the proceeds of this
offering. See "Use of Proceeds." Cash was also used to make regularly scheduled
payments of long-term debt of $511,000 in 1994 and $523,000 in 1995.
 
     The Company's future cash requirements for 1996 and beyond will depend
primarily upon the level of sales expenditures for capital equipment and
improvements, the timing of inventory purchases and new product introductions
and business acquisition opportunities. UniMark believes that anticipated
revenue from operations and existing capital resources will be adequate for its
working capital requirements for at least the next twelve months.

                                    BUSINESS
 
GENERAL
 
     UniMark is a vertically integrated citrus and tropical fruit growing,
processing, marketing and distribution company with operations in Mexico, the
United States and Canada. The UniMark Group, Inc. was organized in 1992 to
combine the operations of ICMOSA, a Mexican citrus and tropical fruit processor
which commenced operations in 1974, with UniMark Foods, a company that marketed
and distributed ICMOSA's products in the United States. The Company focuses on
niche citrus and tropical fruit products including chilled, frozen and canned
cut fruits and other specialty food ingredients. In addition, as a result of its
recent acquisition of GISE, UniMark is a major Mexican producer of citrus
concentrate, oils and juices. The Company processes and packages its products at
nine plants in Mexico, one in California and one in Quebec, Canada. The
Company's Mexican and Californian plants are strategically located in major
fruit growing regions. The Company utilizes food brokers and distributors to
market and distribute its cut fruit products, under the brand names
SUNFRESH(TM), Fruits of Four Seasons(R) and Kledor(R) and under various private
labels to supermarket chains, foodservice distributors, wholesale clubs,
specialty grocery stores and industrial users throughout the United States and
Canada. Under the Jalapeno Sam(R) brand name, the Company also produces
guacamole for distribution in the United States. In addition, the Company has
developed and utilizes a unique processing method that separates cold-peeled
citrus fruit into individual juice-containing "cell-sacs." These cell-sac
products are sold to food and soft drink manufacturers in Japan to enhance the
flavor and texture of fruit juices and desserts. Sales to the Company's Japanese
consumers are facilitated through Japanese trading companies. The Company's
citrus concentrate and single strength citrus juices are sold directly to major
juice importers and distributors in North America, Europe and the Pacific Rim.
 
     The Company has experienced substantial increases in net sales and income
from operations over the past three fiscal years. UniMark's net sales were
$18,893,000, $25,346,000 and $36,866,000, respectively, in its 1993, 1994 and
1995 fiscal years, representing a compound annual growth rate of 39.7% over such
periods. Furthermore, UniMark's income from operations was $633,000, $1,530,000
and $4,251,000, respectively, in such fiscal years, representing a compound
annual growth rate of 159.1% over such periods.
 
STRATEGY
 
     UniMark's strategic objective is to become the leading
vertically-integrated grower, processor, marketer and distributor of niche fruit
and other selected agricultural products. To achieve this objective, the key
elements of UniMark's operating and acquisition strategies are as follows:
 
  Operating Strategy
 
    - Expand vertical integration of growing, processing, marketing and
      distribution operations.  UniMark intends to continue its vertical
      integration strategy. UniMark believes that by vertically integrating its
      growing, processing, marketing and distribution operations, the Company
      can effectively control the availability, cost and quality of its
      products.
 
    - Expand fruit growing operations in Mexico.  To ensure the availability of
      the highest quality raw materials, UniMark intends to expand its fruit
      growing operations in Mexico, utilizing advanced agricultural practices.
      UniMark believes that Mexico's favorable climate and soil conditions,
      coupled with competitive labor and land costs, offer significant
      opportunities to grow high quality fruits in a cost effective manner.
 
    - Capitalize on brand awareness and market penetration.  In the retail
      market, UniMark intends to capitalize on the brand awareness and market
      penetration attained by its SUNFRESH(TM) brand name products. Utilizing
      its "Fruit Made Easy(R)" concept, UniMark plans to expand its line of
      specialty chilled, frozen and canned "ready-to-eat" pre-cut fruit that
      offers the benefits of healthy, low-fat foods with a multitude of vitamins
      to the increasingly health conscious consumer. In the second half of 1996,
      UniMark plans to introduce a line of chilled fruit snack products
      incorporating citrus cell-sacs as a key
 
                                       20
<PAGE>   23
 
      ingredient. UniMark has targeted this planned line of fruit snacks toward
      North American retail and foodservice customers.
 
    - Introduce additional cut fruit products utilizing a cryogenic individual
      quick freeze process.  UniMark intends to expand its retail and
      foodservice business by introducing products utilizing a cryogenic
      individual quick freeze process. UniMark believes that this cryogenic IQF
      process allows UniMark to process citrus and tropical fruit at the peak of
      the season, to preserve the fresh-like texture and taste of the fruit and
      to distribute these products at a later date.
 
    - Continue to expand Japanese exports.  In 1995, the Company's Japanese
      sales represented approximately 32.9% of total sales, compared with only
      17.8% in 1993. As its fastest growing segment, UniMark continues to
      diversify and expand its Japanese customer base. The Company believes that
      there are significant opportunities in Japan for frozen citrus and
      tropical fruit products and specialty food ingredients because such
      products do not contain additives or preservatives, a necessary feature
      for entry into the Japanese market.
 
    - Expand specialty food ingredients.  UniMark believes that significant
      market opportunities exist in providing customers with specialty food
      ingredient products that can be derived from processing citrus and
      tropical fruits. In particular, the Company intends to maximize the
      utilization of its raw materials by identifying secondary food ingredient
      products, such as citrus oils.
 
    - Expand position as a leading Mexican juice exporter to U.S., European and
      Asian markets.  With the GISE Acquisition, the Company is a major Mexican
      producer of citrus concentrate. The Company's goal is to expand its
      position as a leading exporter of high quality Mexican citrus juices to
      the U.S., European and Asian markets. Because of the high quality of
      Mexican citrus juice, it is often blended with juices from other citrus
      producing regions to enhance the quality of these other juices.
 
  Acquisition Strategy
 
    - Acquire productive assets in Mexico that can benefit from UniMark's
      international distribution and marketing expertise.  Most of UniMark's
      processing facilities are strategically located in Mexico's various fruit
      growing regions. UniMark plans to expand its growing and processing
      operations in Mexico because of Mexico's competitive labor and land costs,
      ideal climatic conditions for growing citrus and other fruits and
      vegetables, geographic proximity to the United States and the favorable
      trade benefits of NAFTA. UniMark believes that present economic conditions
      in Mexico, particularly high prevailing interest rates and limited
      availability of equity capital, afford the Company with significant
      acquisition opportunities. In this regard, the Company's acquisition
      strategy targets processing facilities, agricultural opportunities and
      other productive assets in Mexico that can benefit from UniMark's
      international distribution and marketing expertise.
 
    - Acquire food processing companies that possess favorable operating or
      distribution synergies. UniMark's acquisition strategy also targets food
      processing companies, such as Simply Fresh and Deli-Bon, that possess
      favorable operating or distribution synergies. The Company believes that
      by acquiring food processing companies, it can expand its distribution and
      utilize its low cost source of Mexican fruit and labor.
 
RECENT ACQUISITIONS
 
     Since January 1, 1996, the Company has completed the following three
strategic acquisitions (the "Acquisitions") which reflect the implementation of
the Company's acquisition strategy:
 
          GISE.  In May 1996, the Company acquired all of the outstanding shares
     of capital stock of GISE, a major Mexican producer of citrus concentrates,
     oils and juices. GISE's two juice plants are located in Cd. Victoria,
     Tamaulipas, Mexico and Poza Rica, Veracruz, Mexico in the heart of major
     citrus growing regions. UniMark believes that the GISE Acquisition will
     confer operational benefits on both companies resulting from combining
     fruit procurement functions. In addition, UniMark believes that GISE should
 
                                       21
<PAGE>   24
 
     benefit from UniMark's international distribution and marketing expertise.
     Further, the GISE Acquisition significantly increases the Company's
     production capacity of citrus oils.
 
          Simply Fresh.  In May 1996, the Company acquired all of the
     outstanding shares of capital stock of Simply Fresh, a fruit processing and
     distribution company located in Los Angeles, California. Substantially all
     of Simply Fresh's sales are to the foodservice industry in the western
     United States. UniMark believes that the Simply Fresh Acquisition will
     afford it with operating synergies resulting from processing some of the
     fruit used in Simply Fresh's products at UniMark's Mexican plants and
     expanded distribution into the foodservice market. In addition, the Simply
     Fresh plant is strategically located to process fruit grown in California
     and Arizona, two major citrus growing regions with growing seasons that are
     generally opposite to those of Mexico.
 
          Deli-Bon.  In January 1996, the Company acquired all of the
     outstanding shares of capital stock of Deli-Bon. Deli-Bon processes
     primarily fruit salad at its processing plant in Quebec, Canada for
     distribution to the retail and foodservice markets of Canada and the
     northeastern United States. UniMark believes that it will realize
     significant operating synergies from integrating its and Deli-Bon's fruit
     procurement, processing and distribution functions. In addition, the
     Company believes that the Deli-Bon plant is strategically located to
     distribute products to the retail and foodservice markets in Canada and in
     the northeastern United States.
 
CURRENT PRODUCTS
 
     The Company's principal products are derived from citrus and tropical
fruits. The Company has focused on applying its knowledge of fruit growing and
processing with its international marketing and distribution capabilities to
develop four key product categories. These categories include cut fruits,
juices, specialty food ingredients and other products. The following is a
description of each of these categories and their specific products:
 
     CUT FRUITS.  Under the brand names of SUNFRESH(TM), Fruits of Four
     Seasons(R), Kledor(R) and under various private labels, UniMark markets:
 
        Chilled fruit.  The chilled fruit line includes mango slices, grapefruit
        segments, orange segments, pineapple chunks, sliced papaya, and a
        variety of fruit salads. These products are packed for retail, wholesale
        club and foodservice customers.
 
        Frozen fruit.  Using IQF, the frozen line of fruit includes melon,
        mango, orange, grapefruit, papaya and pineapple products packed for
        foodservice and industrial customers.
 
        Canned fruit (shelf-stable).  The canned fruit line includes orange
        segments and grapefruit segments packed for retail, foodservice,
        Japanese and industrial customers.
 
     JUICES.  The Company, through GISE, markets directly to major industrial
     users a full line of citrus juice products including citrus concentrates
     and single strength juices:
 
        Citrus concentrate.  Citrus juice concentrates are produced from
        oranges, grapefruits, tangerines, Persian limes and lemons.
 
        Single strength juices.  Citrus juices are produced from oranges,
        grapefruits, tangerines, Persian limes and lemons.
 
     SPECIALTY FOOD INGREDIENTS.  UniMark believes that significant market
     opportunities exist in providing customers with specialty food ingredient
     products that can be derived from processing citrus and tropical fruits.
     Presently, UniMark's specialty food ingredients include:
 
        Citrus cell-sacs.  The Company has developed and utilizes a unique
        processing method that separates cold-peeled citrus fruit into
        individual juice-containing cell-sacs. These cell-sac products are sold
        to food and soft drink manufacturers in Japan to enhance the flavor and
        texture of fruit juices and desserts.
 
                                       22
<PAGE>   25
 
           Citrus oils.  Citrus oils are extracted from oranges, grapefruits,
           tangerines, Persian limes and lemons. These oils are primarily used
           by the Company's customers in perfumes and other scented products.
 
     OTHER.  UniMark also produces the following products:
 
           Avocado products.  Avocado products, including guacamole and avocado
           pulp, are packed for sale to retail, wholesale club and foodservice
           customers under the brand name Jalapeno Sam(R).
 
           Cattle feed.  The Company recycles citrus byproducts, such as peel
           and pulp, as cattle feed.
 
NEW PRODUCTS
 
     The Company's new product strategy is to apply its processing expertise to
introduce new products as well as extend the line of its existing citrus and
tropical fruit products. UniMark has several major products under development
for projected market introduction during 1996, including:
 
          Additional IQF citrus and tropical fruit.  UniMark intends to expand
     its retail and foodservice business by introducing additional products
     utilizing its IQF process. UniMark believes that this IQF process allows
     UniMark to process citrus and other tropical fruit at the peak of the
     season while preserving the fresh-like texture and taste of the fruit.
 
          Chilled fruit snacks.  In the second half of 1996, UniMark plans to
     introduce a line of chilled fruit snacks incorporating cell-sacs as a key
     ingredient. UniMark has targeted this planned line of fruit snacks toward
     retail and foodservice customers.
 
     UniMark's product development and commercialization efforts are subject to
all of the risks inherent in the development of new products.
 
MARKETING, SALES AND DISTRIBUTION
 
     Marketing.  UniMark's marketing department develops brand strategies for
the Company's existing and new products, including product development, pricing
strategy, consumer and trade promotion, advertising, publicity and package
design. This department's responsibilities include determining the allocation of
resources between consumer and trade spending programs, pricing and
profitability analysis, as well as product and packaging designs. UniMark's
marketing team is led by a senior vice president and two product managers, one
responsible for retail sales and one for the foodservice/wholesale club store
channel.
 
     In the retail market, the Company's primary focus has been on the chilled
fruit category. UniMark intends to capitalize and strengthen the brand awareness
and market penetration attained by its SUNFRESH(TM) brand in the United States,
and the Kledor(R) brand in Canada, and the Jalapeno Sam(R) brand with respect to
Mexican guacamole dip products. Under its "Fruit Made Easy(R)" slogan, UniMark
marketing strategy includes introduction of a comprehensive line of brand name
specialty chilled, frozen and canned "ready-to-eat" pre-cut fruit that offers
the benefits of healthy, low-fat foods with a multitude of vitamins to the
increasingly health conscious consumer. The Company's marketing objectives
include increasing "impulse buying" of its retail products by building greater
product visibility through "eye-catching" package designs, innovative rack
systems and trial package promotions. In addition, the Company utilizes trade
promotions, such as quarterly price allowances, to generate "feature promotion
activity" for its products. The SUNFRESH(TM) product line also receives
substantial advertising support in trade publications and national food shows
throughout the year.
 
     In the foodservice and wholesale club markets, the focus is on securing
market leadership in the chilled fruit category, primarily through private label
programs with major foodservice distributors and a strong branded approach
utilizing the SUNFRESH(TM) and Fruits of Four Seasons(R) labels in the United
States, and Kledor(R) in Canada and the Jalapeno Sam(R) brand in the guacamole
segment. Marketing efforts in these channels are directed toward trade usage
programs and yearly trade rebates.
 
                                       23

     Sales.  UniMark's sales organization consists of five sales management
teams primarily focusing on the management of independent food brokers or
international representatives that directly interface with the customer. These
teams are organized into retail, foodservice, wholesale clubs, Deli-Bon sales in
Canada and Japanese exports.
 
     The retail team is led by a senior vice president of sales and consists of
four regional managers, each with geographic responsibility for approximately 25
percent of the United States. The foodservice team is guided by a vice president
of foodservice sales. The Company plans to divide the United States foodservice
market into three regions (west, central, and east), with a regional sales
manager overseeing each region. The wholesale club market has one sales manager
interfacing directly with key wholesale club distributors.
 
     The Company's Canadian sales team operates out of Deli-Bon and is led by
the president of Deli-Bon and two district sales managers. Deli-Bon uses a
system of independent food brokers throughout Canada although its primary focus
is within the Province of Quebec.
 
     The Company's Japanese exports are directed by an export sales manager
located in Mexico City who deals with agents primarily from Japanese trading
companies. In addition, relationships with the Company's Japanese customers are
handled by the Company's senior executives.
 
     Without giving pro forma effect to the Acquisitions, the following table
shows, for the last three years, the amount and percentage of net sales
contributed by the various market segments for the Company's products:

     Retail sales.  UniMark markets its products to more than 200 regional and
national supermarket chains and wholesalers throughout the United States and
Canada. In conjunction with its own national sales force, UniMark utilizes over
50 independent food brokers and distributors to sell its products.
 
     Japanese sales.  UniMark exports a line of pasteurized citrus products and
juice-containing citrus cell-sac products to Japan for use in the food and
beverage industries. Although sales to industrial customers in Japan are
facilitated through Japanese trading companies, the Company maintains direct
relationships with its industrial customers. During 1993, 1994 and 1995, sales
to the Company's Japanese customers, through Mitsui Foods, Inc., a Japanese
trading company, accounted for approximately 10.7%, 19.5% and 27.5%,
respectively, of the Company's net sales (without giving pro forma effect to the
Acquisitions). UniMark is continuing to diversify and expand its customer base
in the Japanese market. UniMark believes that a significant market opportunity
exists in Japan for frozen citrus and tropical fruit products because such
products do not contain additives or preservatives. UniMark's sales to the
Japanese market have been its fastest growing market segment.
 
     Wholesale club sales.  UniMark indirectly sells products to Sam's Wholesale
Clubs and other wholesale clubs throughout the United States. During 1993, 1994
and 1995, indirect sales to Sam's Wholesale Clubs accounted for approximately
17.5%, 18.5% and 17.6%, respectively, of the Company's net sales.
 
     Foodservice sales.  Sales to the United States government, fast food
chains, restaurants, hospitals and other foodservice customers are made either
directly to or through foodservice distributors by the Company's recently
developed foodservice sales force. UniMark intends to expand its foodservice
business by introducing
 
                                       24
<PAGE>   27
 
additional products utilizing its IQF process. The Company believes that the
foodservice business segment represents an opportunity for significant future
growth.
 
     Industrial and other sales.  Industrial and other sales consist primarily
of IQF melon ball sales to industrial users in the United States for repacking
or further processing. UniMark utilizes an independent food broker to sell its
products to industrial users in the United States.
 
     Distribution.  UniMark operates its own trucking fleet to transport
finished cut fruit products from its Mexican processing facilities to its
distribution center in Hidalgo, Texas. From there, deliveries are made to
UniMark's customers by independent trucking companies. In Canada, deliveries are
made to customers by independent trucking companies from Deli-Bon's facilities.
Products exported to Japan are shipped directly from Mexico. GISE transports
finished product by common carrier to North American customers. Products to
overseas customers are shipped directly in containers.
 
GROWING OPERATIONS
 
     To ensure the availability of the highest quality raw materials, UniMark
intends to expand its fruit growing operations in Mexico, utilizing advanced
agricultural practices. UniMark believes that Mexico's favorable climate and
soil conditions, coupled with competitive labor and land costs, offer
significant opportunities to grow high quality fruits in a cost effective
manner. Presently, a majority of the Company's raw materials are provided by
growers under various arrangements, including operating agreements and
individual fixed price contracts to purchase entire production. The following
table sets forth the Company's various agricultural projects:

- ---------------
 
(1) Villa Azueta is the southern headquarters of UniMark's agricultural
    operations. The agricultural headquarters is used for the development of
    pineapple seedlings, as well as other agricultural crops. In 1995, the
    Company entered into a 10-year lease for this facility and has an option to
    purchase the facility for fair market value determined at the time such
    option is exercised.
 
(2) In 1994, ICMOSA entered into a 10-year operating agreement with the owners
    of a 144 acre grapefruit grove located near the ICMOSA plant in
    Montemorelos. Pursuant to the agreement, ICMOSA operates the grove and
    purchases all the grapefruit at a formula price tied to the price of
    grapefruit purchased from unrelated third parties. The grove consists of
    approximately 13,000 grapefruit trees and incorporates advanced agricultural
    technology. Each tree has a watering and feeding system which can also be
    utilized as an anti-freeze system utilizing mist generated by three 500
    horsepower boilers. Pursuant to the agreement, ICMOSA operates the grove and
    purchases all the grapefruit at a formula price tied to the price of
    grapefruit purchased from unrelated third parties.
 
(3) Presently, approximately 240 of the 625 acres consist of a pink grapefruit
    grove. The Company intends to plant pineapple on approximately 350 of the
    remaining 385 acres of this property.
 
                                       25
<PAGE>   28
 
PROCUREMENT
 
     Currently, a substantial quantity of the fruit processed by the Company is
purchased from third parties. However, the Company's Mexican grapefruit growing
operations supply over 80% of the Company's grapefruit demand. In addition, the
Company purchases grapefruit from growers in the Texas Rio Grande Valley for
processing at its ICMOSA plant. For the 1996 growing season, the Company has
entered into operating agreements with Mexican growers of melons to supply the
Company's anticipated demand for melons. Pursuant to these agreements, the
Company supplies the seeds, fertilizer and insecticides and manages the growing
operations. The Company has entered into similar agreements with Mexican growers
of mangos to supply the Company's anticipated demand for mangos. Substantially
all of the oranges and all of the avocados used in the Company's operations are
purchased from third-party growers throughout Mexico. Presently, UniMark
purchases "Grade A" pineapple from growers throughout Mexico. UniMark has
commenced a significant pineapple growing project. Initial production from this
project is scheduled to begin in 1997 and UniMark intends to expand this project
until 2,400 acres are under cultivation. UniMark believes that production from
this project not only will provide UniMark with a high quality supply of
pineapples for processing but also will produce a significant amount of
pineapple for the North American fresh fruit market.
 
     The Company purchases citrus from growers throughout Mexico. GISE's two
juice plants are located in Cd. Victoria, Tamaulipas, Mexico and Poza Rica,
Veracruz, Mexico in the heart of Mexico's two major citrus growing regions. The
State of Veracruz, located along the east coast of Mexico, is Mexico's largest
orange producing state followed by the neighboring states of Tamaulipas and San
Luis Potosi. Citrus from this region is available for processing at GISE's
Veracruz facility early in the season because of this region's southern
location. GISE's Cd. Victoria plant processes fruit grown primarily in the
northeastern region of Mexico. The fruit is transported by common carrier to
GISE's two plants located in Mexico.
 
PROCESSING
 
     Fruits which will be processed into fruit juice concentrate, fruit juice,
citrus oils and cattle feed, are processed at the Company's Cd. Victoria and
Poza Rica, Mexico facilities. All other products are processed at the Company's
seven remaining facilities in Mexico as well as plants in Los Angeles,
California and Quebec City, Canada, as outlined below.
 
     Cut Fruit.  Upon arrival at the Company's Mexican processing plants, the
fruit is inspected and washed. On the production line, the fruit is manually
peeled and cut into various presentations (slices, sections, chunks, balls).
Following this process, some fruits are further processed into juice-containing
cell-sacs. In addition, some processed fruits are frozen utilizing the Company's
IQF process. Other processed fruits are transferred directly into bulk storage
or final product packaging (pails, jars and cans). After further processing, the
juice-containing cell-sacs are canned while the frozen products are packaged in
plastic bags or trays. The ICMOSA plant is the Company's main plant and serves
as the hub for the Company's other Mexican processing plants, which primarily
produce semi-processed product. At the ICMOSA plant, products are labeled and
packaged for final shipment. ICMOSA also delivers bulk raw materials to Deli-Bon
for packing into final presentations. Only limited processing takes place at
Deli-Bon. The Company cans fruit at its ICMOSA and Puebla plants.
 
     Juice.  GISE's operations are substantially automated. Once the fruit
arrives at a plant, it is unloaded onto rollers. The fruit is then washed and
inspected. Bruised and damaged fruit is removed by hand and the remaining fruit
is then routed to rollers with short needles which extract the oil from the
peel. Once the oil is removed, the fruit is sorted by size to enter into slicing
and squeezing machines. These machines slice the oranges and squeeze the juice
and pulp completely from the peel. The juice is then separated from the pulp.
Upon further processing, the juice is stored on site until it is shipped
directly to customers.

(1) The agreements pursuant to which this facility is leased by the Company
    grants the Company the option to purchase the facility prior to the
    expiration of such agreement at a purchase price equal to the then current
    fair market value of the facility.
 
(2) Presently, the Company is constructing a new storage and repacking facility,
    capable of holding up to approximately 10 million pounds of semi-processed
    and finished product, next to the ICMOSA plant. Construction of this
    facility commenced in February 1996 and is scheduled for completion in
    August 1996.
 
(3) This facility was not in production at December 31, 1995 and commenced
    limited operations in February 1996. The Company anticipates that the level
    of operations conducted at this facility will increase with the facility
    becoming fully operational in 1998. The Company estimates that this facility
    has the capacity to employ as many as 1,000 employees when fully
    operational.
 
(4) This facility has not yet commenced production.
 
RESEARCH AND DEVELOPMENT
 
     The Company's research and development organization provides product,
packaging and process development, analytical and microbiological services, as
well as agricultural research and seed production.
 
EMPLOYEES
 
     As of March 31, 1996, UniMark employed approximately 3,000 full-time
employees, of whom approximately 2,973 were located in Mexico, 41 were located
in the United States and 36 were located in Canada. In Mexico, labor relations
are governed by separate collective labor agreements between UniMark and the
unions representing the particular group of employees. All of UniMark's
employees in Mexico, whether seasonal or permanent, are affiliated with labor
unions which are generally affiliated with a national confederation. Consistent
with other labor practices in Mexico, wages are negotiated every year while
other terms are negotiated every two years.
 
     In the United States and Canada, UniMark's employees are not covered by
collective bargaining agreements. UniMark believes that its relations with all
of its employees are good.
 
COMPETITION
 
     The food industry, including each of the markets in which the Company
competes, is highly competitive with respect to price and quality (including
taste, texture, healthfulness and nutritional value). The Company faces direct
competition from citrus processors with respect to its existing product lines
and faces potential competition from numerous, well established competitors
possessing substantially greater financial, marketing, personnel and other
resources than the Company. The Company's fruit juice products compete broadly
with
 
                                       27
<PAGE>   30
 
all beverages available to consumers. In addition, the food industry is
characterized by frequent introduction of new products, accompanied by
substantial promotional campaigns. In recent years, numerous companies have
introduced products positioned to capitalize on growing consumer preference for
fresh fruit products. It can be expected that the Company will be subject to
increasing competition from companies whose products or marketing strategies
address these consumer preferences.
 
PROPERTIES
 
     In addition to the properties described under "Growing Operations" and
"Processing," the Company maintains corporate headquarters in Lewisville, Texas;
a distribution center in Hidalgo, Texas; a technology development center in Cape
Coral, Florida; and a lodging facility in Cd. Victoria, Tamaulipas, Mexico.
 
     Corporate Headquarters.  UniMark leases approximately 13,000 square feet of
office space for its corporate headquarter in Lewisville, Texas (located 20
miles from the Dallas/Fort Worth International Airport) from an entity
controlled by Jorn Budde, the Company's President, Chief Executive Officer and
Chairman of the Board. As of December 31, 1995, UniMark employed 23 people at
this facility.
 
     The Hidalgo Distribution Center.  The Company's refrigerated distribution
center in Hidalgo, Texas (on the Texas/Mexico border) consists of approximately
22,000 square feet. As of December 31, 1995, 18 people were employed at this
facility.
 
     The UniMark Tech Center.  The Company's tech center is located in Cape
Coral, Florida and consists of approximately 13,000 square feet. A substantial
amount of customized equipment used in the Company's operations are manufactured
at this facility.
 
     The GISE Conference Facility.  In connection with the GISE Acquisition in
May 1996, the Company acquired a "hacienda" which has been declared an historic
landmark. This facility is located near GISE's plant in Cd. Victoria,
Tamaulipas, Mexico, occupies approximately 90,000 square feet and is situated on
approximately 10 acres. The Company intends to utilize this facility, in part,
as a conference center.
 
ENVIRONMENTAL MATTERS
 
     As a result of its agricultural, food and juice processing activities, the
Company is subject to numerous foreign and domestic environmental laws and
regulations.
 
     The operations of UniMark in Mexico are subject to Mexican federal and
state laws and regulations relating to the protection of the environment. The
principal legislation is the federal General Law of Ecological Balance and
Environmental Protection (the "Ecological Law"), which is enforced by the
Ministry of Social Development ("Sedesol"). Under the Ecological Law, rules have
been promulgated concerning water pollution, air pollution, noise pollution and
hazardous substances. Sedesol can bring administrative and criminal proceedings
against companies that violate these environmental laws, and can also close non-
complying facilities. The operations of UniMark in Canada are subject to
Canadian federal and provincial laws and regulations relating to the protection
of the environment including An Act Respecting Occupational Health and Safety
(Quebec), the Canadian Environmental Protection Act (Canada), and the
Environment Quality Act (Quebec). Similarly, the operations of UniMark in the
United States are subject to United States federal and state laws and
regulations relating to the protection of the environment. Although the Company
believes that its facilities currently are in compliance with all applicable
environmental laws, failure to comply with any such laws could have a material
adverse effect on the Company.
 
GOVERNMENT REGULATION
 
     The manufacture, processing, packing, storage, distribution and labeling of
food and juice products is subject to extensive regulations enforced by, among
others, the FDA and state, local and foreign equivalents thereof and to
inspection by the United States Department of Agriculture and other federal,
state, local and foreign agencies. Applicable statutes and regulations governing
food products include "standards of identity" for the content of specific types
of foods, nutritional labeling and serving size requirements and under "Good
Manufacturing Practices" with respect to production processes. The Company
believes that its products
 
                                       28
<PAGE>   31
 
satisfy, and its new products will satisfy, all applicable regulations and that
all of the ingredients used in its products are "Generally Recognized as Safe"
by the FDA for the intended purposes for which they will be used. The Company,
on a daily basis, tests its products at its internal laboratories and, from time
to time, submits samples of its products to independent laboratories for
analysis. Failure to comply with applicable laws and regulations could subject
the Company to civil remedies, including fines, injunctions, recalls or
seizures, as well as potential criminal sanctions, which could have a material
adverse effect on the Company.
 
PRODUCT LIABILITY AND PRODUCT RECALL
 
     The testing, marketing, distribution and sale of food and beverage products
entails an inherent risk of product liability and product recall. There can be
no assurance that product liability claims will not be asserted against the
Company or that the Company will not be obligated to recall its products.
Although the Company maintains product liability insurance coverage in the
amount of $2,000,000 per occurrence, there can be no assurance that this level
of coverage is adequate. A product recall or a partially or completely uninsured
judgment against the Company could have a material adverse effect on the
Company.
 
INTELLECTUAL PROPERTY RIGHTS
 
     The Company regards its trademarks, trade dress, trade secrets and similar
intellectual property as important to its success. The Company has been issued a
registered trademark for its Fruits of Four Seasons(R), Jalapeno Sam(R), Fruit
Made Easy(R) and Kledor(R) trademarks. The Company has filed for trademark
protection for its SUNFRESH(TM) trademark. No assurance can be given that the
Company will be successful in obtaining such trademark protection or that the
trademarks will afford the Company with any competitive advantages. In
connection with the Simply Fresh Acquisition, the Company has acquired patent
rights with respect to certain fruit cutting machinery.
 
LEGAL PROCEEDINGS
 
     From time to time the Company is involved in litigation relating to claims
arising from its operation in the normal course of business or otherwise. As of
the date of this Prospectus, the Company is not a party to any legal
proceedings, the adverse outcome of which individually or in the aggregate, in
the Company's opinion, would have a material adverse effect on the Company's
results of operations or financial condition.

     A maximum of 100,000 shares of Common Stock (subject to certain

of options granted under the Directors' Option Plan. Currently, options for
67,500 shares of Common Stock have been granted under the Directors' Option Plan
to Messrs. Stone, Jordaan and Camacho, all of which are currently exercisable.
The average exercise price of such options is $3.90 per share.
 
     Stock options may be granted under the Directors' Option Plan to any
director who is not an employee of the Company and is not a holder of more than
1% of the outstanding shares of the Company's Common Stock or a person who is in
control of such holder ("Eligible Directors").
 
     Eligible Directors automatically receive an initial grant of options to
purchase 20,000 shares of Common Stock upon their appointment to the Board of
Directors, and annual grants of options to purchase 2,500 shares of Common Stock
as of the date following each annual meeting of the Company's shareholders. The
exercise price of options granted under the Directors' Option Plan will be at
least the fair market value of a share of the Common Stock on the date of grant.

exercisable. The expiration date of each option is not more than six years from
the date of grant. Payment for shares purchased upon exercising an option are
made in cash or by certified check, bank draft or money order,

pursuant to the Employee's Option Plan may either be incentive stock options
within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Internal Revenue Code"), or non-qualified stock options. The
number of shares of Common Stock originally reserved for issuance pursuant to
the Plan was 480,000 shares. As of May 1, 1996, options for 380,000 shares of
Common Stock were outstanding under the Employee's Option Plan at an average
exercise price of $4.20 per share.
 
     The Employee's Option Plan is administered by the Compensation Committee of
the Board of Directors. Subject to the provisions of the Employee's Option Plan,
the Compensation Committee has the exclusive power to interpret the Employee's
Option Plan, to grant waivers of restrictions thereunder and to adopt such rules
and regulations as it may deem necessary or appropriate in keeping with the
objectives of the Employee's Option Plan.
 
     Options granted pursuant to the Employee's Option Plan become exercisable
on such date or dates as may be established by the Compensation Committee. The
exercise price of options granted under the Employee's Option Plan may not be an
amount less than the market value of Common Stock at the time of grant. The
exercise price must be paid in full in cash at the time an option is exercised
or, if permitted by the Compensation Committee, by means of tendering previously
owned shares of Common Stock, or partly in cash and partly in Common Stock.

     In the event of a stock split, stock dividend, combination or
reclassification or certain other corporate transactions, the Compensation
Committee is authorized to make appropriate adjustments to the exercise price
and number of shares subject to options granted under the Employee's Option
Plan. Subject to certain limitations, the Board of Directors is authorized to
amend, modify or terminate the Employee's Option Plan to meet any changes in
legal requirements for any other purpose permitted by law.
 
INDEMNIFICATION AND LIMITATION ON LIABILITY
 
     The Company's Articles of Incorporation, as amended, and By-laws, as
amended, provide that the Company shall indemnify all directors and officers of
the Company to the fullest extent permitted by the Texas Business Corporation
Act. Under such provisions, any director or officer, who in his capacity as
such, is made or threatened to be made, a party to any suit or proceeding, may
be indemnified if it is determined that such director or officer acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interest of the Company. In addition, the By-laws contain certain provisions
intended to facilitate receipt of such benefits.
 
     As authorized by the Texas Miscellaneous Corporation Laws Act, UniMark's
Articles of Incorporation, as amended, provide that the Company's directors will
have no personal liability to UniMark or its shareholders for monetary damages
for breach or alleged breach of the directors' duty of care. This provision has
no effect on director liability for (i) a breach of the directors' duty of
loyalty to the Company or its shareholders, (ii) acts or omissions not in good
faith that constitute a breach of duty of a director or involving intentional
misconduct or knowing violations of law, (iii) approval of any transaction from
which a director derives an improper personal benefit, or (iv) an act or
omission for which the liability of a director is expressly provided by an
applicable statute. In addition, the Company's Articles of Incorporation, as
amended, provide that any additional liabilities permitted to be eliminated by
subsequent legislation will automatically be eliminated without further
shareholder vote, unless additional shareholder approval is required by such
legislation.
 
     The principal effect of the limitation of liability provision is that a
shareholder is unable to prosecute an action for monetary damages against a
director of the Company unless the shareholder can demonstrate one of the
specified bases for liability.
 
     This provision does not eliminate a director's duty of care. However, the
inclusion of this provision in the Company's Articles of Incorporation, as
amended, may discourage or deter shareholders or management from bringing a
lawsuit against directors for a breach of their fiduciary duties, even though
such an action, if successful, might otherwise have benefitted the Company and
its shareholders. This provision should not affect the availability of equitable
remedies such as an injunction or rescission based upon a director's breach of
the duty of care. Furthermore, it does not eliminate or limit director liability
arising in connection with causes of action brought under the federal securities
laws.
 
                              CERTAIN TRANSACTIONS
 
     Effective January 2, 1995, the Company entered into a five-year operating
agreement with Industrias Horticolas de Montemorelos, S.A. de C.V. ("IHMSA") to
operate a freezing plant located in Montemorelos, Nuevo Leon, Mexico. Pursuant
to the terms of the operating agreement, the Company has agreed to pay IHMSA an
operating fee sufficient to cover the interest payments on IHMSA's outstanding
debt. This debt is denominated in U.S. dollars and has an outstanding principal
amount of approximately $4,600,000. Interest on this debt is charged at variable
rates ranging from 9.8% to 15.5%. The Company is responsible for all raw
material and operating costs and the sale of the finished goods produced at the
IHMSA plant. Payments made pursuant to the operating agreement were $347,090
during the year ended December 31, 1995. During the term of the operating
agreement, the Company has a right of first refusal to buy the IHMSA facility at
its fair market value as determined at the time the right of first refusal is
exercised. The family of Messrs. Rafael Vaquero Bazan, Eduardo Vaquero Bazan and
Pedro Vaquero Garcia owns an approximate 8% interest in IHMSA. The Company
believes that said arrangement is no less favorable to the Company than would be
available from unrelated third parties.
 
                                       34

     Effective July 1, 1995, the Company entered into a ten-year operating
agreement with Azteca to operate a processing plant in Montemorelos, Nuevo Leon,
Mexico. The operating agreement provides for payments in the amount of interest
of approximately $220,000 on Azteca's existing debt and asset and property
taxes. During the six-month period ended December 31, 1995, payments made
pursuant to the operating agreement were approximately $25,000. During the term
of the operating agreement, the Company has a right of first refusal to buy the
Azteca facility at its then fair market value. Prior to July 1, 1995, Azteca
co-packed chilled grapefruit sections and mango slices for the Company. During
the six-month period ended June 30, 1995, Azteca co-packed approximately $1.4
million of fruit for the Company. During the year ended December 31, 1995, the
aggregate amount of payments made to Azteca was $143,095. The Company believes
that said arrangements are no less favorable to the Company than would be
available from unrelated third parties. At December 31, 1995 Azteca owned an
approximate 9.2% interest in the Company. The Vaquero family owns collectively
an approximate 14.3% interest in Azteca.
 
     In November 1995, the Company entered into a lease agreement with Loma
Bonita Partners, a Texas general partnership, for approximately 200 hectares
(approximately 494 acres) of land located in Loma Bonita, Veracruz, Mexico for
the development of citrus groves. The lease commenced in December 1995 and
expires in ten years. Messrs. Jorn Budde and Rafael Vaquero are the two general
partners of Loma Bonita Partners. Rent expense on this lease was $5,670 for the
month of December 1995. The Company believes that said lease agreement is on
terms no less favorable to the Company than would be available from unrelated
third parties.
 
     The Company operates a 144 acre grapefruit grove located close to the
ICMOSA plant in Montemorelos, Mexico pursuant to a ten year operating agreement
that expires in 2000. Pursuant to the agreement, the Company operates the grove
and purchases all the grapefruit produced at a formula price tied to purchases
from unrelated third parties. During 1995, the Company purchased approximately
$156,000 of grapefruit pursuant to this agreement. The grove is owned by a
partnership that consists primarily of shareholders of Azteca. The Vaquero
family collectively owns an approximate 14.3% interest in this partnership. The
Company believes that said arrangement is on terms no less favorable to the
Company than would be available from unrelated third parties.
 
     The Company leases its corporate office facility from an entity controlled
by Mr. Budde. Rent expense on this lease was approximately $36,000 for the year
ended December 31, 1995. The Company believes that said arrangement is on terms
no less favorable to the Company than would be available from unrelated third
parties.
 
     During 1995, the Company paid Jordaan, Howard and Pennington, PLLC an
amount of $106,145 for legal services rendered. Mr. Jordaan, a director of the
Company, is a member of Jordaan, Howard & Pennington, PLLC. The Company believes
that said arrangement is on terms no less favorable to the Company than would be
available from unrelated third parties.
 
FUTURE TRANSACTIONS
 
     Although the Company intends that the terms of any future transactions and
agreements between the Company and its directors, officers, principal
shareholders or other affiliates will be no less favorable than could be
obtained from unaffiliated third parties, no assurances can be given in this
regard. Any such future transactions that are material to the Company and are
not in the ordinary course of business will be approved by a majority of the
Company's independent and disinterested directors.

provided by law.
 
     Under the Texas Business Corporation Act, shareholders may take certain
actions without the holding of a meeting by a written consent or consents signed
by the holders of a majority of the outstanding shares of the capital stock of
the Company entitled to vote thereon. Prompt notice of the taking of any action
without a meeting by less than unanimous consent of the shareholders is required
to be given to those shareholders who do not consent in writing to the action.
The purposes of this provision are to facilitate action by shareholders and to
reduce the corporate expense associated with annual and special meetings of
shareholders. Pursuant to the rules and regulations of the Commission, if
shareholder action is taken by written consent, the Company will be required to
send each shareholder entitled to vote on the applicable matter, but whose
consent was not solicited, an information statement containing information
substantially similar to that which would have been contained in a proxy
statement.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock and Warrants is
Harris Trust and Savings Bank, N.A., Chicago, Illinois.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have 8,261,833 shares of
Common Stock outstanding. All of the 1,400,000 shares sold by the Company in
this offering will be freely transferable without further restriction or
registration under the Securities Act, except for any shares purchased by an
"affiliate" of the Company (as defined under the Securities Act). Of these
8,261,833 shares of Common Stock, 2,541,951 shares are "restricted securities"
under applicable securities laws. Additional shares of Common Stock may become
eligible for sale in the public market from time to time upon exercise of
warrants and stock options.
 
     Holders of restricted securities must comply with the requirements of Rule
144 in order to sell their shares in the open market. In general, under Rule 144
as currently in effect, any affiliate of the Company and any person (or persons
whose sales are aggregated) who has beneficially owned his or her restricted
shares for at least two years, would be entitled to sell in the open market
within any three-month period a number of shares that does not exceed the
greater of: (i) 1% of the then outstanding shares of the Company's Common Stock
(approximately 82,600 shares immediately after this offering); or (ii) the
average weekly trading volume reported on the Nasdaq National Market System
during the four calendar weeks preceding such sale. Sales under Rule 144 are
also subject to certain limitations on manner of sale, notice requirements, and
availability of current public information about the Company. Nonaffiliates who
have held their restricted shares for three years are entitled to sell their
shares under Rule 144 without regard to any of the above limitations, provided
they have not been affiliates of the Company for the three months preceding such
sale. As of May 1, 1996, options to acquire a total of 380,000 shares and 67,500
shares are outstanding under the Employees' Option Plan and the Directors'
Option Plan, respectively. An additional 87,000 shares and 32,500 shares are
available for future option grants under the Employees' Option Plan and the
Directors' Option Plan, respectively. See "Management -- Compensation of
Directors -- Employee Stock Option Plan."
 
     The Company can make no prediction as to the effect, if any, that sales of
shares of Common Stock or the availability of shares for sale will have on the
market price of Common Stock. Nevertheless, sales of significant amounts of
Common Stock could adversely affect the prevailing market price of Common Stock,
as well as impair the ability of the Company to raise capital through the
issuance of additional equity securities.

     The Underwriting Agreement provides that the obligations of the several
Underwriters thereunder are subject to approval of certain legal matters by
counsel and to various other considerations. The nature of the Underwriters'
obligations is such that they are committed to purchase and pay for all of the
above shares of Common Stock if any are purchased.
 
     The Underwriters, through the Representatives, have advised the Company
that they propose to offer the Common Stock initially at the public offering
price set forth on the cover page of this Prospectus; that the Underwriters may
allow to selected dealers a concession of $          per share, and that such
dealers may reallow a concession of $      per share to certain other dealers.
After the public offering, the offering price and other selling terms may be
changed by the Underwriters. The Common Stock is included for quotation on the
Nasdaq National Market.
 
     The Company and certain of the Selling Shareholders have granted to the
Underwriters a 30-day over-allotment option to purchase up to an aggregate of
300,000 additional shares of Common Stock, exercisable at the public offering
price less the underwriting discount. If the Underwriters exercise such
over-allotment option, then each of the Underwriters will have a firm
commitment, subject to certain conditions, to purchase approximately the same
percentage thereof as the number of shares of Common Stock to be purchased by it
as shown in the above table bears to the 2,000,000 shares of Common Stock
offered hereby. The Underwriters may exercise such option only to cover
over-allotments made in connection with the sale of the shares of Common Stock
offered hereby.
 
     The officers, directors, principal shareholders and Selling Shareholders of
the Company have agreed that they will not sell or dispose of any shares of
Common Stock of the Company for a period of 180 days after the later of the date
on which the Registration Statement is declared effective by the Commission or
the first date on which the shares are bona fide offered to the public, without
the prior written consent of the Representatives.
 
     The Company and the Selling Shareholders have agreed to indemnify the
Underwriters against certain liabilities, losses and expenses, including
liabilities under the Securities Act, or to contribute to payments that the
Underwriters may be required to make in respect thereof.
 
     In connection with the offering made hereby, certain Underwriters and
selling group members (if any) or their respective affiliates who are qualified
registered market makers on the Nasdaq National Market may engage in passive
market making transactions in the Common Stock on the Nasdaq National Market in
accordance with Rule 10b-6A under the Exchange Act, during a specified period
before commencement of offers or sales of the Common Stock. The passive market
making transactions must comply with applicable volume and price limits and be
identified as such. In general, a passive market maker may display its bid at a
price not in excess of the highest independent bid for such security; if all
independent bids are lowered below the passive market maker's bid, however, such
bid must then be lowered when certain purchase limits are exceeded.

             PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION
                                  (UNAUDITED)
 
     On January 3, 1996, the Company acquired all the outstanding shares of
capital stock of Les Produits Deli-Bon Inc. ("Deli-Bon"), a Quebec corporation,
which is a processor of fruit and primarily targets the foodservice industry.
Total consideration for the purchase of the shares included approximately: (i)
$787,000 in cash; (ii) a $49,000 six-month promissory note and (iii) 28,510
shares of Common Stock.
 
     On May 9, 1996, the Company acquired all the outstanding shares of capital
stock of Grupo Industrial Santa Engracia, S.A. de C.V., a Mexican company
("GISE"), which is a processor of citrus concentrate, oils and juices. Total
consideration for the purchase of the shares included 782,614 shares of Common
Stock and contingent consideration of up to an additional $8.0 million of Common
Stock or cash if certain future earnings targets are achieved.
 
     Also on May 9, 1996, the Company acquired all the outstanding shares of
capital stock of Simply Fresh Fruit, Inc., a California corporation ("Simply
Fresh"), which is a processor of fruit and primarily targets the foodservice
industry. Total consideration for the purchase of the shares included
approximately: (i) $2,500,000 in cash; (ii) 90,909 shares of Common Stock and
(iii) $1 million in cash payable in consideration for a five-year covenant not
to compete.
 
     The unaudited pro forma condensed consolidated balance sheet of the
Company, GISE, Simply Fresh and Deli-Bon, as of December 31, 1995, reflects
these acquisitions as if they had occurred on December 31, 1995.
 
     The unaudited pro forma condensed consolidated statement of income for the
year ended December 31, 1995 reflects these acquisitions as if they had occurred
on January 1, 1995.
 
     Historically, Simply Fresh has purchased fresh fruit on the open market for
processing at their facility in Los Angeles, California. UniMark intends to
provide Simply Fresh with fresh fruit processed at its facilities in Mexico at a
significant cost savings to Simply Fresh. UniMark is exercising its plan to
initially provide pineapple and melons to Simply Fresh this season. Accordingly,
a reduction in Simply Fresh's cost of products sold equal to the estimated cost
savings (Simply Fresh's actual cost minus UniMark's cost delivered to Los
Angeles) of UniMark providing 50% of the pineapple and melons processed by
Simply Fresh during 1995 has been reflected as an adjustment in the unaudited
pro forma condensed consolidated statement of income.
 
     The unaudited pro forma condensed consolidated balance sheet and statement
of income should be read in conjunction with the separate historical financial
statements of the Company, GISE, Simply Fresh and Deli-Bon, and related notes
appearing elsewhere in this Prospectus. The pro forma financial information is
not necessarily indicative of the results that would have been reported had such
events actually occurred on the dates specified, nor is it necessarily
indicative of the future results of the combined Company.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
The UniMark Group, Inc.
 
     We have audited the accompanying consolidated balance sheets of the UniMark
Group, Inc. (the Company) as of December 31, 1994 and 1995, and the related
consolidated statements of income, shareholders' equity, and cash flows for each
of the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our 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 consolidated financial position of
The UniMark Group, Inc. at December 31, 1994 and 1995, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1995, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES
 
     Description of Business: The UniMark Group, Inc. ("the Company") was
incorporated in the state of Texas on January 3, 1992. During the period from
January 3, 1992 (inception) through December 31, 1992, 3,000,000 shares of the
Company's common stock were exchanged for the issued and outstanding common
shares of UniMark Foods, Inc., which was owned by the same shareholders as the
Company. Since the companies were under common control, the transaction was
accounted for using historical costs. Additionally, 800 shares of common stock
of UniMark International, Inc. were acquired for $800 during that same period,
giving the Company an 80% interest which was increased to a 100% interest with
the acquisition of the remaining 200 shares during 1994. On August 11, 1994,
1,300,950 shares of the Company's common stock were exchanged for all of the
issued and outstanding common shares of Industrias Citricolas de Montemorelos,
S.A. de C.V. ("ICMOSA"), a Mexican corporation. The transaction was accounted
for in a manner similar to a pooling-of-interests using historical costs and,
accordingly, the accompanying financial statements include the accounts and
operations of ICMOSA for all periods prior to the stock exchange. The Company is
in the principal business of growing, processing, marketing and distributing
niche citrus and tropical fruit products, including chilled and canned cut
fruits and other specialty food ingredients.
 
     Principles of Consolidation: The consolidated financial statements include
the accounts of The UniMark Group, Inc. and its subsidiaries, all of which are
wholly owned. All significant intercompany accounts and transactions have been
eliminated.
 
     Foreign Operations: A significant portion of the Company's operations are
located in Mexico and a significant portion of the Company's fruit is procured
in Mexico. In addition, substantially all of ICMOSA's employees are affiliated
with labor unions. As is typical in Mexico, wages are renegotiated every year
while other terms are negotiated every two years. Recently, Mexico has faced
turbulent political and economic times. Should political unrest spread or
political leadership or other causes vastly change economic conditions in
Mexico, the Company's operations could be adversely affected.
 
     Use of Estimates: The preparation of the financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
     Cash Equivalents: The Company considers all highly liquid investments with
original maturities of three months or less when purchased to be cash
equivalents.
 
     Concentration of Credit Risk: The Company manufactures and sells niche
citrus and tropical fruit products and other specialty food ingredients to
customers in the foodservice and retail industries in the United States, Canada
and Japan. The Company performs periodic credit evaluations of its customers'
financial condition and generally does not require collateral. Trade receivables
generally are due within 30 days. Credit losses have been within management's
expectations. A significant portion of sales is made to two customers. One
customer accounted for 10.7%, 19.5% and 27.5% and another customer accounted for
17.5%, 18.5% and 17.6% of the Company's net sales during the years ended
December 31, 1993, 1994 and 1995, respectively.
 
     Inventories: Inventories held in the United States are carried at the lower
of cost or market using the first-in, first-out method. Mexican inventories are
valued at the lower of cost or market using average historical cost.

     Foreign Currency Transactions: The functional currency of the Company and
its subsidiaries is the United States dollar. Transactions in foreign currency
are recorded at the prevailing exchange rate on the day of the related
transaction. Assets and liabilities denominated in foreign currency are
remeasured to dollars at the prevailing exchange rate as of the balance sheet
date. Exchange rate differences are reflected in the current year's operations.
 
     Income Taxes: Deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to reverse.
 
     Earnings Per Share: Earnings per share are calculated based on the weighted
average number of common and common equivalent shares outstanding during each
period. The modified treasury stock method is utilized to measure the dilutive
effect of options and warrants.
 
     In 1993 and 1994, outstanding stock options and warrants were antidilutive
and the weighted average numbers of common shares used in this calculation were
3,000,000 and 3,642,000, respectively. In 1995, the weighted average number of
common and common equivalent shares used in the primary and fully diluted
calculations were 5,609,000 and 5,805,000, respectively. For purposes of the
1995 net income per share computation, net income was adjusted for the pro forma
reduction of interest expense, net of income taxes, resulting from the assumed
use of warrant and option proceeds to reduce outstanding debt.
 
     Part of the proceeds from the Company's initial public offering were
applied to retire $1,535,000 of short-term debt. Had the retirement taken place
at the beginning of 1994, net income per common share for 1994 would have been
$0.27, based upon a weighted average number of shares of common stock
outstanding of 3,938,000.

NOTE 4 -- SHORT-TERM BORROWINGS
 
     ICMOSA has a revolving line-of-credit arrangement with a bank for
short-term dollar denominated debt in Mexico of up to $6,000,000 collateralized
by accounts receivable from export sales to Japan. This line of credit
commitment, which had an outstanding balance of $1,545,000 at December 31, 1995,
has no scheduled maturity but is reviewed annually for renewal.
 
     The Company also has a line-of-credit arrangement with a bank for
short-term debt in the United States ("U.S.") of up to $3,000,000 collateralized
by U.S. accounts receivable and finished goods inventories. This line of credit,
which had an outstanding balance of $2,000,000 at December 31, 1995, matures on
April 30, 1997. The U.S. line of credit requires, among other things, the
maintenance of certain financial covenants and ratios; the timely presentation
of financial information; and restricts the payment of dividends.
 
     The weighted average interest rate on short-term borrowings as of December
31, 1995 was 8.4%.

     In November, 1995, the Company entered into a lease agreement with Loma
Bonita Partners, a Texas general partnership, for approximately 200 hectares
(494 acres) of land located in Loma Bonita, Veracruz, Mexico for the development
of citrus groves. The lease commenced in December, 1995 and expires in ten
years. Loma Bonita Partners is owned equally by two officers, who are also
directors and shareholders of the Company. The Company believes that said lease
agreement is on terms no less favorable to the Company than would be available
from unrelated third parties. Rent expense on this lease was $5,670 for the year
ended December 31, 1995.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The balance due from shareholders at December 31, 1995 represents unsecured
advances and unsecured notes receivable made to shareholders. These advances and
notes receivable are payable on demand, and bear interest at 0% and 10%,
respectively.
 
     The Company operates a 144 acre grapefruit grove located close to the
ICMOSA plant in Montemorelos pursuant to a ten year operating agreement that
expires in 2000. Per the agreement, the Company operates the grove and purchases
all the grapefruit produced at a formula price tied to purchases from unrelated
third parties. The grove is owned by a partnership that consists primarily of
shareholders of Azteca. The Vaquero family owns a 14.3% interest in this
partnership. The Company believes that said arrangement is on terms no less
favorable to the Company than would be available from unrelated third parties.
 
     The Company leases its corporate office facility from a company owned by
the Company's president, who is also a shareholder of the Company. Rent expense

option is granted, provided that the exercise period may not be greater than 10
years from the date of grant. The exercise price of any option granted under the
employee stock option plan shall not be less than 100% and 85% of the fair
market value of the stock on the date of the grant for Incentive Stock Options
and Nonstatutory Stock Options, as defined, respectively. The exercise price of
any option granted under the outside directors stock option plan shall not be
less than 100% of the fair market value of the stock on the date of the grant.

NOTE 10 -- WARRANTS
 
     On August 11, 1994, the Company completed an initial public offering of
550,000 units consisting of a total of 1,650,000 shares of its common stock and
1,100,000 Redeemable Common Stock Purchase Warrants ("the Warrants"). The
Warrants were transferable separately from the common stock and entitled the
holder to purchase one share of the Company's common stock at an exercise price
of $4.50 per share at any time until the fifth anniversary of the offering.
Commencing February 11, 1995, the Company could redeem some or all of the
Warrants at a call price of $0.05 per Warrant upon 30 days prior notice when the
closing bid quotation of the common stock had equaled or exceeded $6.75 for ten
consecutive trading days. The Company reserved 1,100,000 shares for issuance
upon the exercise of the Warrants.
 
     On June 8, 1995 the Company notified all registered holders of the Warrants
of its intention to redeem all of the outstanding Warrants by July 21, 1995. The
Company issued 1,099,990 shares of common stock on the exercise of a like amount
of the Warrants with gross proceeds to the Company of $4,949,955.
 
     In conjunction with the initial public offering on August 11, 1994, the
Company issued warrants to its underwriting representatives ("the
Representatives' Warrants") to purchase up to 55,000 units consisting of a total
of 165,000 shares of its common stock and 110,000 Redeemable Common Stock
Purchase Warrants. The Representatives' Warrants are exercisable for a period of
five years from the offering date at a price per unit of $15.00. The Company
reserved 275,000 shares for issuance upon the exercise of the Representatives'
Warrants and the underlying Redeemable Common Stock Purchase Warrants. During
1995, the Company issued 163,060 shares of common stock on the exercise of
32,612 Representatives' Warrants and the 65,224 underlying Redeemable Common
Stock Purchase Warrants with gross proceeds to the Company of $782,688.
 
NOTE 11 -- RESTRICTIONS ON RETAINED EARNINGS
 
     Under Mexican Commercial Law, 5% of each year's Mexican income must be
allocated to a legal reserve until such reserve reaches 20% of ICMOSA's capital
stock amount. ICMOSA's capital stock amount is $2,151,000 at December 31, 1995.
This reserve cannot be distributed to the shareholders except in the form of
stock dividends.
 
     Under the terms of the U.S. line of credit agreement with a bank, the
Company may not declare or pay any dividends on its shares without the bank's
prior written consent.

To the shareholder of
Les Produits Deli-Bon Inc.
 
     We have audited the balance sheet of Les Produits Deli-Bon Inc. as at
January 2, 1996 and January 31, 1995 and the statements of earnings, retained
earnings and changes in financial position for the period of eleven months ended
January 2, 1996 and for the year ended January 31, 1995. These financial
statements are the responsibility of the company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance 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.
 
     In our opinion, these financial statements present fairly, in all material
respects, the financial position of the company as at January 2, 1996 and
January 31, 1995 and the results of its operations and the changes in its
financial position for the period of eleven months ended January 2, 1996 and for

1. ACCOUNTING POLICIES
 
     Currency -- All amounts are presented in Canadian dollars ($Cdn).
 
     Inventories --
 
          Inventories are valued at the lower of cost using the first-in
     first-out method, and market value. Market value is defined as net
     realizable value.
 
     Fixed assets and depreciation --
 
          Fixed assets are recorded at cost and depreciation is calculated using
     the declining-balance method at the following rates:
 
<TABLE>
        <S>                                                             <C>
        Building......................................................            5%
        Pavement......................................................            8%
        Machinery and equipment.......................................           20%

        Research and development equipment............................           20%
</TABLE>
 
          These rates are reduced by half for acquisitions made during the year.
 
     Deferred grants --
 
          Grants and investment tax credits related to fixed assets are recorded
     as deferred grants during the year they are received. Depreciation is
     calculated using the declining-balance method at the same rate as the
     concerned fixed assets.
 
     Income taxes --
 
          The company follows the deferral method of income tax allocation.
     Income taxes are provided at current rates for all items included in the
     statement of earnings regardless of the period when such items are reported

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 financial statements referred to above present fairly,
in all material respects, the financial position of Grupo Industrial Santa

                               DECEMBER 31, 1995
                              (THOUSANDS OF PESOS)
1. ACCOUNTING POLICIES
 
DESCRIPTION OF BUSINESS
 
     Grupo Industrial Santa Engracia, S.A. de C.V. is a Mexican company based in
Cd. Victoria, Tamaulipas. The Company is engaged in the processing of fruit,
mainly citrus, to make natural juice, concentrated juice and citrus oils.
 
     Since the raw materials are of natural origin, their price and availability
depend on circumstances that are out of the Company's control, so that the cycle
and volume of operations is variable.
 
     The Company was constituted on August 2, 1988, and began operations in
December 1989.
 
BASIS OF FINANCIAL STATEMENTS
 
     The Company's accounting records are maintained in Mexican pesos and in
accordance with accounting principles generally accepted in Mexico. The
accompanying financial statements were prepared in conformity with accounting
principles generally accepted in the United States of America and were obtained
from the accounting records after giving effect to the following:
 
     -- Canceling the effects of inflation on fixed assets.
 
     -- Recording deferred income taxes.
 
USE OF ESTIMATES
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid investments with original
maturities of 90 days or less when purchased to be cash equivalents.
 
CONCENTRATION OF CREDIT RISK
 
     The Company provides credit to its customers in the normal course of
business. The Company performs ongoing credit evaluations of its customers and
maintains allowances for possible credit losses, which, when realized, have been
within the range of management's expectations. A significant portion of sales is
made to two customers. One customer accounted for 34.8% and another customer
accounted for 10.1% of the Company's net sales during the year ended December
31, 1995.
 
INVENTORIES
 
     Inventories are valued at the lower of cost or market. Cost is calculated
at average historical cost.

PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment is stated at cost. Depreciation is calculated
by the straight-line method, at the rates indicated below:

    Buildings...................................................................    4.00%

    Transportation equipment....................................................   12.00%
    Computer equipment..........................................................    7.00%
    Office equipment............................................................    7.00%
    Installation expenses.......................................................   10.00%
</TABLE>
 
TERMINATION PAYMENTS
 
     Termination payments due to workers under the terms of Mexican Labor Law
are charged to the results of operations in the year in which the decision to
dismiss the employee is made.
 
SENIORITY PREMIUMS
 
     Seniority premiums are recognized as a cost during the years of service of
the personnel. This cost should be determined using independent actuarial
computations and applying the projected unitary credit method; however, at
December 31, 1995 the Company's Management estimated this liability on a
different base, determining and recording an amount of Ps 100. This figure was
considered to be sufficient at that date to meet the requirement, and Management
intends to obtain an actuarial study in 1996.
 
     No actuarial study was performed in 1994, and no accrual recorded. It is
the Company's opinion that, had such a study been performed, the amount which
would have been recorded would not have materially affected the accompanying
financial statements for 1994.
 
TRANSACTIONS IN FOREIGN CURRENCY
 
     Transactions in foreign currency are recorded at the prevailing exchange
rate on the day of the related transaction. Assets and liabilities denominated
in foreign currency are translated into Mexican pesos at the prevailing exchange
rate as of the balance sheet date. Exchange rate differences are reflected in
the current year's operations.

paid can be credited against the total amount of income tax payable in excess of
the asset tax in the succeeding ten years.
 
     During 1995, for tax purposes, the Company depreciated the investments in
fixed assets made in that year on an accelerated basis at rates of 74% and 85%
of their original cost in accordance with the terms of Mexican Income Tax Law.
As a consequence of this accelerated depreciation, the Company obtained an
additional benefit in accordance with Asset Tax Law in regard to the Company's
right to off-set the asset tax for the year against 34% of the difference
between the accelerated depreciation of new investments in 1995 and the tax
depreciation in accordance with normal tax rates.
 
     The balance between the asset tax for the year and the total of the benefit
mentioned in the prior paragraph amounts to Ps 3,319, and it can be off-set
against asset tax for subsequent years.
 
     Both the tax loss carry forwards and the benefit amortizable against asset
tax were included as deferred asset tax, as described in Note 6.
 
6. DEFERRED TAXES
 
     In the preparation of these financial statements, the Company adopted the
provisions of Statement of Financial Accounting Standards No. 109 (SFAS No.
109), "Accounting for Income Taxes." Under SFAS No. 109, the liability method is
used in accounting for income taxes. Accordingly, deferred tax assets and
liabilities are determined based on differences between financial reporting and
tax bases of assets and liabilities, and are determined using the enacted tax
laws and rates that will be in effect when the differences are expected to
reverse.
 
     The Company also has permanent differences between its accounting and
taxable income, mainly related to the inflationary component and nondeductible
expenses, as well as differences between book and inflation-adjusted tax
depreciation.

7. RESTRICTIONS ON RETAINED EARNINGS
 
     Under Mexican Commercial Law, 5% of each year's income must be allocated to
a legal reserve until such reserve reaches 20% of the capital stock (Ps2,754).
This reserve can only be distributed to the shareholders in the form of stock
dividends.
 
8. SUBSEQUENT EVENTS
 
     During the period of January 1 to April 30, 1996, the Company contracted
loans with Rabobank Curacao and Arka Securities Inc. for Ps13,909 to use as
working capital.
 
     On May 9, 1996, all of the outstanding shares of the Company's common stock
were acquired by The UniMark Group, Inc.

The Board of Directors
Simply Fresh Fruit, Inc.
 
     We have audited the accompanying balance sheet of Simply Fresh Fruit, Inc.,

the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing

reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Simply Fresh Fruit, Inc., at
December 31, 1995 and the results of its operations and its cash flows for the

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1. ORGANIZATION
 
     The Company was incorporated in the state of California in January 1983.
The Company is located in Los Angeles, and is a wholesale processor, packager
and seller of fresh fruit and a fresh fruit mix.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Use of Estimates
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with original
maturities of 90 days or less when purchased to be cash equivalents.
 
  Concentration of Credit Risk
 
     The Company manufactures and sells citrus products and certain food
products to customers in the foodservice and retail industries in the United
States. The Company performs periodic credit evaluations of its customers'
financial condition and generally does not require collateral. Trade receivables
generally are due within 30 days. Credit losses have been within management's
expectations. A significant portion of sales is made to two customers. One
customer accounted for 10.4% and another customer accounted for 19.2% of the
Company's net sales during the year ended December 31, 1995.
 
  Inventory
 
     Inventory is stated at the lower of cost or market determined on a
first-in, first-out basis.
 
  Property, Plant and Equipment
 
     Property, plant, and equipment are stated at cost. Depreciation expense is
calculated using straight-line and declining balance methods over lives ranging
from five to ten years and includes depreciation on assets under capital lease.
 
  Patent License
 
     The patent license is being amortized over its expected useful life of five
years using the straight-line method.
 
  Income Taxes
 
     The Company utilizes the liability method of accounting for income taxes as
set forth in Statement of Financial Accounting Standards No. 109, "Accounting
for Income Taxes." Under this method, deferred tax assets and liabilities are
determined based on differences between the financial reporting and tax bases of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Fair Value of Financial Instruments
 
     Management estimates the fair value of notes payable to approximate their
carrying value at December 31, 1995 based upon current market interest rates in
relation to the stated and imputed interest rates and the relative liquidity of
each instrument.

* To be completed by Amendment.
 
ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Article 2.02-1 of the Texas Business Corporation Act permits a corporation
to indemnify a person who was or is a director, officer, employee, or agent of a
corporation or who serves at the corporation's request as a director, officer,
partner, proprietor, trustee, employee, or agent of another corporation,
partnership, trust, joint venture, or other enterprise (an "outside
enterprise"), who was, is, or is threatened to be named a defendant in a legal
proceeding by virtue of such person's position in the corporation or in an
outside enterprise, but only if the person acted in good faith and reasonably
believed, in the case of conduct in the person's official capacity, that the
conduct was in or, in the case of all other conduct, that the conduct was not
opposed to the corporation's best interest, and, in the case of a criminal
proceeding, the person had no reasonable cause to believe the conduct was
unlawful. A person may be indemnified within the above limitations against
judgments, fines, settlements, and reasonable expenses actually incurred.
Generally, an officer, director, agent, or employee of a corporation or a person
who serves at the corporation's request as an officer, director, agent, or
employee of an outside enterprise may not be indemnified, however, against
judgments, fines, and settlements incurred in a proceeding in which the person
is found liable to the corporation or is found to have improperly received a
personal benefit and may not be indemnified for expenses unless, and only to the
extent that, in view of all the circumstances, the person is fairly and
reasonably entitled to indemnification for such expenses. A corporation must
indemnify a director, officer, employee, or agent against reasonable expenses
incurred in connection with a proceeding in which the person is a party because
of the person's corporate position, if the person was successful, on the merits
or otherwise, in the defense of the proceeding. Under certain circumstances, a
corporation may also advance expenses to such person.
 
     Article 2.02-1 of the Texas Business Corporation Act also permits a
corporation to purchase and maintain insurance or to make other arrangements on
behalf of any of the above persons against any liability asserted against and
incurred by the person in such capacity, or arising out of the person's status
as such a person, whether or not the corporation would have the powers to
indemnify the person against the liability under applicable law.
 
     The Company's Articles of Incorporation, as amended, provide that the
Company's directors will have no personal liability to the Company or its
shareholders for monetary damages for breach or alleged breach of the directors'
duty of care. This provision has no effect on director liability for (i) a
breach of the directors' duty of loyalty to the Company or its shareholders,
(ii) acts or omissions not in good faith that constitute a breach of duty of a
director or involving intentional misconduct or knowing violations of law, (iii)
approval of any
 
                                      II-1
<PAGE>   96
 
transaction from which a director derives an improper personal benefit, or (iv)
an act or omission for which the liability of a director is expressly provided
by an applicable statute. In addition, the Company's Articles of Incorporation,
as amended, provide that any additional liabilities permitted to be eliminated
by subsequent legislation will automatically be eliminated without further
shareholder vote, unless additional shareholder approval is required by such
legislation. Article VI of the Company's Bylaws also provides that the Company
will indemnify its directors, officers, employees and agents to the fullest
extent permitted by the Texas Business Corporation Act. The Company is generally
required to indemnify its directors, officers, employees, and agents against all
judgments, fines, settlements, legal fees, and other expenses incurred in
connection with pending or threatened legal proceedings because of the person's
position with the Company or another entity that the person serves at the
Company's request, subject to certain conditions, and to advance funds to enable
them to defend against such proceedings. In addition, the Bylaws contain certain
provisions intended to facilitate receipt of such benefits.
 
     The Underwriting Agreement entered into by the Company and the
Representatives in connection with this offering provides that the
Representatives will indemnify the directors and officers of the Company against
certain liabilities including liabilities under the Securities Act.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.
 
     In May 1996, in connection with the GISE Acquisition, UniMark issued
782,614 shares of Common Stock to the holders of the outstanding shares of
capital stock of GISE.
 
     In May 1996, in connection with the Simply Fresh Acquisition, UniMark
issued 90,909 shares of Common Stock to the holders of the outstanding shares of
capital stock of Simply Fresh.
 
     In January 1996, in connection with the Deli-Bon Acquisition, UniMark
issued 28,510 shares of Common Stock to Gestion Michel Baribeau, Inc.
 
     Effective upon the Company's initial public offering in August 1994,
holders of all the outstanding shares of capital stock of ICMOSA (the "ICMOSA
Holders") exchanged all outstanding shares of ICMOSA stock for shares of
UniMark's Common Stock (the "ICMOSA Exchange"). In connection with the ICMOSA
Exchange, UniMark issued 1,300,950 shares of Common Stock to the ICMOSA Holders,
representing approximately 43.4 percent of UniMark's Common Stock outstanding
immediately prior to the offering or approximately 28 percent of UniMark's
Common Stock outstanding immediately after the offering. All of the ICMOSA
Holders are Mexican nationals and none are citizens or residents of the United
States. As part of the ICMOSA Exchange, each ICMOSA Holder has agreed not to
sell any shares of UniMark Common Stock in the United States without the consent
of UniMark for a period of two years.
 
     Exemption from registration with respect to the above-described sales was
claimed under Section 4(2) of the Securities Act regarding transactions by an
issuer not involving any public offering, under Rules 506 promulgated under the
Securities Act and Regulation S under the Securities Act.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes it will:
 
          Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the registrant pursuant to the foregoing provisions,
     or otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Securities Act and is, therefore, unenforceable.
     In the event that a claim for indemnification against such liabilities
     (other than the payment by the registrant of expenses incurred or paid by a
     director, officer or controlling person of the registrant in the successful
     defense of any action, suit or proceeding) is asserted by such director,
     officer or controlling person in connection with the securities being
     registered, the registrant will, unless in the opinion of its counsel the
     matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Securities Act and will be
     governed by the final adjudication of such issue.
 
          For purposes of determining any liability under the Securities Act,
     the information omitted from the form of prospectus filed as a part of this
     registration statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Securities Act shall be deemed to be part of the
     registration statement as of the time it was declared effective. 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.

On behalf of the Several
Underwriters named in
Schedule I attached hereto.

Ladies and Gentlemen:

         The Unimark Group, Inc., a Texas corporation (the "Company") and the
shareholders of the Company named in Schedule II attached hereto (the "Selling
Shareholders"), propose to sell to you and the other underwriters named in
Schedule I attached hereto (the "Underwriters"), for whom you are acting as the
Representatives, an aggregate of 2,000,000 shares (the "Firm Shares") of the
Company's Common Stock, $.01 par value per share (the "Common Stock") of which
1,400,000 shares (the "Company Shares") are to be issued and sold by the
Company and 600,000 shares (the "Selling Shareholder Shares") are to be sold by
the Selling Shareholders.  In addition, (i) the Company proposes to grant to
the Underwriters an option to purchase up to an additional 277,000 shares (the
"Company Option Shares") and (ii) certain Selling Shareholders as set forth on
Schedule II, (the "Certain Selling Shareholders") propose to grant an option to
purchase 23,000 shares (the "Selling Shareholder Option Shares" and together
with the Company Option Shares, the "Option Shares"), of Common Stock for the
purpose of covering over-allotments in connection with the sale of the Firm
Shares.  The Firm Shares and the Option Shares are together called the
"Shares."

         1.      Sale and Purchase of the Shares.  On the basis of the
representations, warranties and agreements contained in, and subject to the
terms and conditions of, this Agreement:

                 (a)      The Company agrees to issue and sell the Company
         Shares and the Selling Shareholders agree to sell the Selling
         Shareholder Shares to the several Underwriters, and each of the
         Underwriters agrees, severally and not jointly, to purchase at the
         purchase price per share
<PAGE>   2
         of Common Stock of $________ (the "Initial Price"), the aggregate
         number of Firm Shares set forth opposite such Underwriter's name in
         Schedule I attached hereto.  The Underwriters agree to offer the Firm
         Shares to the public as set forth in the Prospectus.

                 (b)      The Company grants to the several Underwriters an
         option to purchase all or any part of the Company Option Shares, and
         the Certain Selling Shareholders grant to the several Underwriters an
         option to purchase all or any part of the Selling Shareholder Option
         Shares, at the Initial Price.  The number of Option Shares to be
         purchased by each Underwriter shall be the same percentage (adjusted
         by the Representatives to eliminate fractions) of the total number of
         Option Shares to be purchased by the Underwriters as such Underwriter
         is purchasing of the Firm Shares.  Such option may be exercised only
         to cover over-allotments in the sales of the Firm Shares by the
         Underwriters and may be exercised in whole or in part at any time on
         or before 12:00 noon, New York City time, on the business day before
         the Firm Shares Closing Date (as defined below), and from time to time
         thereafter within 30 days after the date of this Agreement, upon
         written or telegraphic notice, or verbal or telephonic notice
         confirmed by written or telegraphic notice, by the Representatives to
         the Company or the Certain Selling Shareholders no later than 12:00
         noon, New York City time, on the business day before the Firm Shares
         Closing Date or at least two business days before any Option Shares
         Closing Date (as defined below), as the case may be, setting forth the
         number of Option Shares to be purchased and the time and date (if
         other than the Firm Shares Closing Date) of such purchase.

         2.      Delivery and Payment.  Delivery by the Company and the Selling
Shareholders of the Firm Shares to the Representatives for the respective
accounts of the Underwriters, and payment of the purchase price by certified or
official bank check or checks payable in New York Clearing House (next day)
funds to the Company and the Selling Shareholders, shall take place at the
offices of Rodman & Renshaw, Inc., at One Liberty Plaza, 165 Broadway, New
York, New York, 10006, at 10:00 a.m., New York City time, on the [THIRD]
business day following the date on which the public offering of the Shares
commences (unless such date is postponed in accordance with the provisions of
Section 10(b)), or at such time and place on such other date, not later than 10
business days after the date of this Agreement, as shall be agreed upon by the
Company, the Selling Shareholders and the Representatives (such time and date
of delivery and payment are called the "Firm Shares Closing Date").  The public
offering of the Shares shall be deemed to have commenced at the time, which is
the earlier of (a) the time, after the Registration Statement (as defined in
Section 4 below) becomes effective, of the release by you for publication of
the first newspaper advertisement which is subsequently published relating to
the Shares or (b) the time, after the Registration Statement becomes effective,
when the Shares are first released by you for offering by the Underwriters or
dealers by letter or telegram.

         In the event the option with respect to the Option Shares is
exercised, delivery by the Company of the Company Option Shares or the Certain
Selling Shareholders of the Selling Shareholder Option Shares, to the
Representatives for the respective accounts of the Underwriters and payment of
the purchase price by certified or official bank check or checks payable in New
York Clearing House (next day) funds to the Company or the Certain Selling
Shareholders, as the case may be, shall take place at the offices of Rodman &
Renshaw, Inc. specified above at the time and on the date (which may be the
same date as, but in no event shall be earlier than, the Firm Shares Closing
Date) specified in the notice referred to in Section 1(b) (such time and date
of delivery and payment is called the "Option Shares Closing Date").  The Firm
Shares Closing Date and the Option Shares Closing Dates are called,
individually, a "Closing Date" and, together, the "Closing Dates."

         Certificates evidencing the Shares shall be registered in such names
and shall be in such denominations as the Representatives shall request at
least two full business days before the Firm Shares Closing Date or the Option
Shares Closing Date, as the case may be, and shall be made available to the
Representatives for checking and packaging, at such place as is designated by
the Representatives, on the full business day before the Firm Shares Closing
Date or the Option Shares Closing Date, as the case may be.

         3.      Public Offering.  The Company and the Selling Shareholders
understand that the Underwriters propose to make a public offering of the
Shares, as set forth in and pursuant to the Prospectus (as defined in Section 4
below), as soon after the effective date of the Registration Statement and the
date of this Agreement, as the Representatives deem advisable.  The Company and
the Selling Shareholders hereby confirm that the Underwriters and dealers have
been authorized to distribute or cause to be distributed each Preliminary
Prospectus and are authorized to distribute the Prospectus (as from time to
time amended or supplemented if the Company furnishes amendments or supplements
thereto to the Underwriters).

         4.      Representations and Warranties of the Company and the Selling
Shareholders.

                 (a)      The Company represents and warrants to, and agrees
         with, the several Underwriters that:

                            (i)   The Company has filed with the Securities and
                 Exchange Commission (the "Commission") a registration
                 statement, and may have filed one or more amendments thereto,
                 on Form S-1 (Registration No. 333-________), including in such
                 registration statement and each such amendment a related
                 preliminary prospectus (a "Preliminary Prospectus"), for the
                 registration of the Shares and the Option Shares, in
                 conformity with the requirements of the Securities Act of
                 1933, as amended (the "Act").  In addition, the Company has
                 filed or will promptly file a further amendment to such
                 registration statement, in the form heretofore delivered to
                 you.  As used in this Agreement, the term "Registration
                 Statement" means such registration statement, as amended, on
                 file with the Commission at the time such registration
                 statement becomes effective (including the prospectus,
                 financial statements, exhibits, and all other documents filed
                 as a part thereof or incorporated by reference directly or
                 indirectly therein (such incorporated documents being herein
                 collectively "Incorporated Documents")), provided that such
                 Registration Statement, at the time it becomes effective, may
                 omit such information as is permitted to be omitted from the
                 Registration Statement when it becomes effective pursuant to
                 Rule 430A of the General Rules and Regulations promulgated
                 under the Act (the "Regulations"), which information ("Rule
                 430 Information") shall be deemed to be included in such
                 Registration Statement when a final prospectus is filed with
                 the Commission in accordance with Rules 430A and 424(b)(1) or
                 (4) of the Regulations; the term "Preliminary Prospectus"
                 means each prospectus included in the Registration Statement,
                 or any amendments thereto, before it becomes effective under
                 the Act, the form of prospectus omitting Rule 430A Information
                 included in the Registration Statement when it becomes
                 effective, if applicable (the "Rule 430A Prospectus"), and any
                 prospectus filed by the Company with your consent pursuant to
                 Rule 424(a) of the Regulations; and the term "Prospectus"
                 means the final prospectus included as part of the
                 Registration Statement, except that if the prospectus relating
                 to the





                                       3
<PAGE>   4
                 securities covered by the Registration Statement in the form
                 first filed on behalf of the Company with the Commission
                 pursuant to Rule 424(b) of the Regulations shall differ from
                 such final prospectus, the term "Prospectus" shall mean the
                 prospectus as filed pursuant to Rule 424(b) from and after the
                 date on which it shall have first been used.

                           (ii)   When the Registration Statement becomes
                 effective, and at all times subsequent thereto to and
                 including the Closing Dates, and during such longer period as
                 the Prospectus may be required to be delivered in connection
                 with sales by the Underwriters or a dealer, the Registration
                 Statement (and any post-effective amendment thereto) and the
                 Prospectus (as amended or as supplemented if the Company shall
                 have filed with the Commission any amendment or supplement to
                 the Registration Statement or the Prospectus) will contain all
                 statements which are required to be stated therein in
                 accordance with the Act and the Regulations, will comply with
                 the Act and the Regulations, and will not contain any untrue
                 statement of a material fact or omit to state any material
                 fact required to be stated therein or necessary to make the
                 statements therein not misleading, and no event will have
                 occurred which should have been set forth in an amendment or
                 supplement to the Registration Statement or the Prospectus
                 which has not then been set forth in such an amendment or
                 supplement; if a Rule 430A Prospectus is included in the
                 Registration Statement at the time it becomes effective, the
                 Prospectus filed pursuant to Rules 430A and 424(b)(1) or (4)
                 will contain all Rule 430A Information; and each Preliminary
                 Prospectus, as of the date filed with the Commission, did not
                 include any untrue statement of a material fact or omit to
                 state any material fact required to be stated therein or
                 necessary to make the statements therein not misleading;
                 except that no representation or warranty is made in this
                 Section 4(a)(ii) with respect to statements or omissions made
                 in reliance upon and in conformity with written information
                 furnished to the Company as stated in Section 7(b) with
                 respect to any Underwriter by or on behalf of such Underwriter
                 through the Representatives expressly for inclusion in any
                 Preliminary Prospectus, the Registration Statement, or the
                 Prospectus, or any amendment or supplement thereto.  Each of
                 the Incorporated documents complies in all material respects
                 with the requirements of the Securities Exchange Act of 1934,
                 as amended (the "Exchange Act"), and the rules and regulations
                 thereunder.

                          (iii)   Neither the Commission nor the "blue sky" or
                 securities authority of any jurisdiction has issued an order
                 (a "Stop Order") suspending the effectiveness of the
                 Registration Statement, preventing or suspending the use of
                 any Preliminary Prospectus, the Prospectus, the Registration
                 Statement, or any amendment or supplement thereto, refusing to
                 permit the effectiveness of the Registration Statement, or
                 suspending the registration or qualification of the Firm
                 Shares or the Option Shares nor has any of such authorities
                 instituted or threatened to institute any proceedings with
                 respect to a Stop Order.

                           (iv)   Any contract, agreement, instrument, lease,
                 or license required to be described in the Registration
                 Statement or the Prospectus has been properly described
                 therein.  Any contract agreement, instrument, lease, or
                 license required to be filed as an exhibit to the Registration
                 Statement has been filed with the Commission as an exhibit to
                 or has been incorporated as an exhibit by reference into the
                 Registration Statement.

                            (v)   The Company has no subsidiaries and does not
                 control, directly or indirectly, any corporation, partnership,
                 joint venture, association or other business organization,
                 except for Simply Fresh Fruit, Inc., a California corporation
                 ("Simply Fresh"), Unimark Foods, Inc., a Texas corporation
                 ("UFI"), Unimark International, Inc., a Texas corporation
                 ("UII" and together with UFI, the "Texas Subsidiaries"),
                 Industrias Citricolas De Montemorelos, S.A. De C.V., a Mexican
                 entity ("ICMOSA"), Grupo Industries Santa Engracia, a Mexican
                 entity ("GISE", and together with ICMOSA the "Mexican
                 Subsidiaries") Les Produits Deli-Bon, Inc., a company
                 organized under the laws of Canada, ("Deli-Bon") (each such
                 corporation singly a "Subsidiary" and collectively the
                 "Subsidiaries").  Each of the Company and each Subsidiary is a
                 corporation duly organized, validly existing, and in good
                 standing under the laws of the jurisdiction in which it is
                 chartered, with full corporate power and authority, and all
                 necessary consents, authorizations, approvals, orders,
                 licenses, certificates, and permits of and from, and
                 declarations and filings with, all federal, state, local, and
                 other governmental authorities and all courts and other
                 tribunals, to own, lease, license, and use its properties and
                 assets and to carry on its business as now being conducted and
                 in the manner described in the Prospectus.  Each of the
                 Company and each Subsidiary has been duly qualified to do
                 business and is in good standing in each jurisdiction in which
                 its respective ownership, leasing, licensing, or character,
                 location or use of property and assets or the conduct of its
                 respective business makes such qualification necessary.

                           (vi)   The authorized capital stock of the Company
                 consists of 20,000,000 shares of Common Stock, of which
                 8,261,828 shares are outstanding.  Each outstanding share of
                 Common Stock has been duly and validly authorized and issued,
                 fully paid, and non-assessable, without any personal liability
                 attaching to the ownership thereof and has not been issued and
                 is not owned or held in violation of any preemptive rights of
                 shareholders.  The Company owns all of the shares of capital
                 stock of the Subsidiaries, free and clear of all liens,
                 claims, security interests, restrictions, shareholders'
                 agreements, voting trusts and any other encumbrances
                 whatsoever.  There is no commitment, plan, preemptive right or
                 arrangement to issue, and no outstanding option, warrant, or
                 other right calling for the issuance of, shares of capital
                 stock of the Company or any of the Subsidiaries or any
                 security or other instrument which by its terms is convertible
                 into, exercisable for, or exchangeable for capital stock of
                 the Company or any of the Subsidiaries, except as described in
                 the Prospectus.  There is outstanding no security or other
                 instrument which by its terms is convertible into or
                 exchangeable for capital stock of the Company or any of the
                 Subsidiaries, except as described in the Prospectus.

                          (vii)   The consolidated financial statements of the
                 Company and the Subsidiaries, together with the related notes
                 thereto, included in the Registration Statement and the
                 Prospectus fairly present with respect to their respective

                 information purported to be shown therein at the respective
                 dates and for the respective periods to which they apply.
                 Such financial statements have been prepared in accordance
                 with generally accepted accounting principles (except to the
                 extent that certain footnote disclosures regarding any stub
                 period may have been omitted in accordance with the applicable

                 the Company and the Subsidiaries.  The pro forma financial
                 statements and other pro forma financial information
                 (including the notes thereto) included in the Registration
                 Statement and the Prospectus (A) present fairly in all
                 material respects the information shown therein, (B) have been

                 applicable requirements of Rule 11-02 of Regulation S-X
                 promulgated under the Exchange Act, and (C) have been properly
                 computed on the basis described therein.  The assumptions used
                 in the preparation of the pro forma financial statements and
                 other pro forma financial information included in the
                 Registration Statement and the Prospectus are reasonable and
                 the adjustments used therein are appropriate to give effect to
                 the transactions or circumstances referred to therein.  The
                 accountants whose reports on the audited financial statements
                 are filed with the Commission as a part of the Registration
                 Statement are, and during the periods covered by their
                 report(s) included in the Registration Statement and the
                 Prospectus were, independent certified public accountants with
                 respect to the Company within the meaning of the Act and the
                 Regulations.  No other financial statements are required by
                 Form S-1 or otherwise to be included in the Registration
                 Statement or the Prospectus.  There has at no time been a
                 material adverse change in the financial condition, results of
                 operations, business, properties, assets, liabilities, or
                 future prospects of the Company or any of the Subsidiaries
                 from the latest information set forth in the Registration
                 Statement or the Prospectus, except as may be properly
                 described in the Prospectus.

                         (viii)   There is no litigation, arbitration, claim,
                 governmental or other proceeding (formal or informal), or
                 investigation before any court or before any public body or
                 board pending, or to the knowledge of the Company, threatened,
                 with respect to the Company or any of the Subsidiaries, or any
                 of their respective operations, businesses, properties or
                 assets, except as may be properly described in the Prospectus
                 or such as individually or in the aggregate do not now have
                 and will not in the future have a material adverse effect upon
                 the operations, businesses, properties, assets or financial
                 condition of the Company and the Subsidiaries.  Neither the
                 Company nor any of the Subsidiaries is involved in any labor
                 dispute, nor is such dispute threatened, which dispute would
                 have a material adverse effect upon the operations, business,
                 properties, assets or financial condition of the Company.
                 Neither the Company nor any of the Subsidiaries is in
                 violation of, or in default with respect to, any law, rule,
                 regulation, order, judgment, or decree; nor is the Company or
                 any of the Subsidiaries required to take any action in order
                 to avoid any such violation or default.  The Company and the
                 Subsidiaries (A) are in compliance with any and all applicable
                 foreign, federal, state and local laws and regulations
                 relating to the protection of human health and safety, the
                 environment or hazardous or toxic substances or wastes,
                 pollutants or contaminants ("Environmental Laws"), (B) have
                 received all permits, licenses or other approvals required of
                 them under applicable Environmental Laws to conduct their
                 respective businesses and (C) are in compliance with all terms
                 and conditions of any such permit, license or approval, except
                 where such noncompliance with Environmental Laws, failure to
                 receive required permits, licenses or other approvals or
                 failure to comply with the terms and conditions of such
                 permits, licenses or approvals would not, individually or in
                 the aggregate, have a material adverse effect upon the
                 financial condition, assets, operations or prospects of the
                 Company and the Subsidiaries, taken as a whole.

                           (ix)   The Company and each of the Subsidiaries has
                 good and marketable title in fee simple absolute to all real
                 properties and good title to all other properties and assets
                 which the Prospectus indicates are owned by it, and has valid
                 and enforceable leasehold interests in each of such items free
                 and clear of all liens, security interests, pledges, charges,
                 encumbrances, and mortgages (except as may be properly
                 described in the Prospectus).  No real property owned, leased,
                 licensed or used by the Company or any of the Subsidiaries
                 lies in an area which is, or to the knowledge of the Company
                 will be, subject to zoning, use or building code restrictions
                 which would prohibit, and no state of facts relating to the
                 actions or inaction of another person or entity or his or its
                 ownership, leasing, licensing or use of any real or personal
                 property exists or will exist which would prevent, the
                 continued effective ownership, leasing, licensing or use of
                 such real property in the business of the Company or any of
                 the Subsidiaries as presently conducted or as the Prospectus
                 indicates it contemplates conducting (except as may be
                 properly described in the Prospectus).

                            (x)   The Company and each of the Subsidiaries, and
                 to the knowledge of the Company, any other party, is not now
                 or is not expected by the Company to be in violation or breach
                 of, or in default with respect to, complying with any term,
                 obligation or provision of any contract, agreement,
                 instrument, lease, license, indenture, mortgage, deed of
                 trust, note, arrangement or understanding which is material to
                 the Company or any of the Subsidiaries or by which any of its
                 properties or businesses may be bound or affected, and no
                 event has occurred which with notice or lapse of time or both
                 would constitute such a default, and each such contract,
                 agreement, instrument, lease, license, indenture, mortgage,
                 deed of trust, note, arrangement or understanding is in full
                 force and is the legal, valid and binding obligation of the
                 parties thereto and is enforceable as to them in accordance
                 with its terms.  The Company and each of the Subsidiaries
                 enjoy peaceful and undisturbed possession under all leases and
                 licenses under which it is operating.  Neither the Company nor
                 any of the Subsidiaries is a party to or bound by any
                 contract, agreement, instrument, lease, license, indenture,
                 mortgage, deed of trust, note, arrangement or understanding,
                 or subject to any charter or other restriction, which has had
                 or may in the future have a material adverse effect on the
                 financial condition, results of operations, businesses,
                 properties, assets, liabilities or future prospects of the
                 Company and the Subsidiaries.  Neither the Company nor any of
                 the Subsidiaries is in violation of breach of, or in default
                 with respect to, any term of its certificate of incorporation
                 (or other charter document) or by-laws or of any franchise,
                 license, permit, judgment, decree, order, statute, rule or
                 regulation.

                           (xi)   The Company and the Subsidiaries have filed
                 all federal, state, local and foreign tax returns which are
                 required to be filed through the date hereof, or have received
                 extensions thereof, and have paid all taxes shown on such
                 returns and all assessments received by it to the extent that
                 the same are material and have become due.

                          (xii)   Any patents, patent applications, trademarks,
                 trademark applications, trade names, service marks,
                 copyrights, copyright applications, franchises, and other
                 intangible properties and assets listed in the Registration
                 Statement (all of the foregoing being collectively herein
                 called "Intangibles") that the Company and the Subsidiaries
                 own, possess or have pending, or under which they are
                 licensed, are in good standing

                 and uncontested. There is no right under any Intangible
                 necessary to the business of the Company or the Subsidiaries
                 as presently conducted or as the Prospectus indicates the
                 Company contemplates conducting (except as may be so described
                 in the Prospectus).  Neither the Company nor any of the
                 Subsidiaries has infringed, is infringing, or has received any
                 notice of infringement with respect to asserted Intangibles of
                 others.  To the knowledge of the Company, there is no
                 infringement by others of Intangibles of the Company.  To the
                 knowledge of the Company, there is no Intangible of others
                 which has had or may in the future have a materially adverse
                 effect on the financial condition, results of operations,
                 business, properties, assets, liabilities or future prospects
                 of the Company and the Subsidiaries.

                         (xiii)   Neither the Company nor any Subsidiary,
                 director, officer, agent, employee or other person associated
                 with or acting on behalf of the Company and the Subsidiaries
                 has, directly or indirectly:  used any corporate funds for
                 unlawful contributions, gifts, entertainment, or other
                 unlawful expenses relating to political activity; made any
                 unlawful payment to foreign or domestic government officials
                 or employees or to foreign or domestic political parties or
                 campaigns from corporate funds; violated any provision of the
                 Foreign Corrupt Practices Act of 1977, as amended; or made any
                 bribe, rebate, payoff, influence payment, kickback, or other
                 unlawful payment.  No transaction has occurred between or
                 among the Company, the Subsidiaries, or the Selling
                 Shareholders and any of its or their officers or directors or
                 any affiliates or affiliates of any such officer or director,
                 except as described in the Prospectus.

                          (xiv)   The Company has all requisite power and
                 authority to execute, deliver and perform this Agreement.  All
                 necessary corporate proceedings of the Company have been duly
                 taken to authorize the execution, delivery and performance of
                 this Agreement.  This Agreement has been duly authorized,
                 executed, and delivered by the Company, is the legal, valid
                 and binding obligation of the Company, and is enforceable as
                 to the Company in accordance with its terms.  No consent,
                 authorization, approval, order, license, certificate or permit
                 of or from, or declaration or filing with, any federal, state,
                 local or other governmental authority or any court or other
                 tribunal is required by the Company or the Subsidiaries for
                 the execution, delivery or performance by the Company of this
                 Agreement (except filings under the Act which have been or
                 will be made before the applicable Closing Date and such
                 consents consisting only of consents under "blue sky" or
                 securities laws which have been obtained at or prior to the
                 date of this Agreement).  No consent of any party to any
                 contract, agreement, instrument, lease, license, indenture,
                 mortgage, deed of trust, note, arrangement or understanding to
                 which the Company or the Subsidiaries are a party, or to which
                 any of their respective properties or assets are subject, is
                 required for the execution, delivery or performance of this
                 Agreement, and the execution, delivery and performance of this
                 Agreement, will not violate, result in a breach of, conflict
                 with, accelerate the due date of any payments under, or (with
                 or without the giving of notice or the passage of time or
                 both) entitle any party to terminate or call a default under
                 any such contract, agreement, instrument, lease, license,
                 indenture, mortgage, deed of trust, note, arrangement or
                 understanding, or violate or result in a breach of any term of
                 the certificate of incorporation (or other charter document)
                 or by-laws of the Company or any of the Subsidiaries, or
                 violate, result in a breach of, or conflict with any law,
                 rule, regulation, order, judgment or

                 decree binding on the Company or any of the Subsidiaries or to
                 which any of their operations, business, properties or assets
                 are subject.

                           (xv)   The Company Shares and the Option Shares are
                 validly authorized.  The Firm Shares, when issued and
                 delivered in accordance with this Agreement, and the Option
                 Shares, when delivered in accordance with this Agreement, will
                 be duly and validly issued, fully paid, and non-assessable,
                 without any personal liability attaching to the ownership
                 thereof, and will not be issued in violation of any preemptive
                 rights of shareholders, optionholders, warrantholders and any
                 other persons and the Underwriters will receive good title to
                 the Company Shares and Option Shares purchased by them,
                 respectively, free and clear of all liens, security interests,
                 pledges, charges, encumbrances, shareholders' agreements and
                 voting trusts.

                 Option Shares conform to all statements relating thereto
                 contained in the Registration Statement or the Prospectus.

                 which information is given in the Registration Statement and
                 the Prospectus, and except as may otherwise be properly
                 described therein, there has not been any material adverse
                 change in the assets or properties, business or results of
                 operations or financial condition of the Company or the
                 Subsidiaries, whether or not arising from transactions in the
                 ordinary course of business; neither the Company nor the
                 Subsidiaries has sustained any material loss or interference

                 earthquake, flood or other calamity, whether or not covered by
                 insurance; since the date of the latest balance sheet included
                 in the Registration Statement and the Prospectus, except as
                 reflected therein, neither the Company nor the Subsidiaries
                 has undertaken any liability or obligation, direct or
                 contingent, except for liabilities or obligations undertaken
                 in the ordinary course of business; and neither the Company
                 nor the Subsidiaries has (A) issued any securities or incurred

                 redeem, purchase or otherwise acquire any shares of its
                 capital stock.

                        (xviii)   Neither the Company nor any of its officers,
                 directors or affiliates (as defined in the Regulations), has
                 taken or will take, directly or indirectly, prior to the
                 termination of the underwriting syndicate contemplated by this
                 Agreement, any action designed to stabilize or manipulate the
                 price of any security of the Company, or which has caused or
                 resulted in, or which might in the future reasonably be
                 expected to cause or result in, stabilization or manipulation
                 of the price of any security of the Company, to facilitate the
                 sale or resale of any of the Firm Shares or the Option Shares.

                           (xx)   The Company is not, and does not intend to
                 conduct its business in a manner in which it would be, an
                 "investment company" as defined in Section 3(a) of the
                 Investment Company Act of 1940 (the "Investment Company Act").

                          (xxi)   No person or entity has the right to require
                 registration of shares of Common Stock or other securities of

                 contemplated by this Agreement.

                        (xxiii)   No transaction has occurred between or among
                 the Company, the Subsidiaries, and any of their officers or

                 that is required to be described in and is not described in

                 authorized for quotation on the NASDAQ National Market.

                          (xxv)   Neither the Company, the Subsidiaries, nor
                 any of their affiliates is presently doing business with the
                 government of Cuba or with any person or affiliate located in
                 Cuba.  If, at any time after the date that the Registration
                 Statement is declared effective with the Commission or with
                 the Florida Department of Banking and Finance (the "Florida
                 Department"), whichever date is later, and prior to the end of
                 the period referred to in the first clause of Section 4(a)(ii)
                 hereof, the Company commences engaging in business with the
                 government of Cuba or with any person or affiliate located in
                 Cuba, the Company will so inform the Florida Department within
                 ninety days after such commencement of business in Cuba, and
                 during the period referred to in Section 4(a)(ii) hereof will
                 inform the Florida Department within ninety days after any
                 change occurs with respect to previously reported information.

         represent and warrant to, and agree with, the several Underwriters
         that:

                            (i)   Such Selling Shareholder has deposited in

                 Chicago, Illinois as custodian (the "Custodian"), certificates
                 in negotiable form for the Selling Shareholder Shares to be
                 sold hereunder by such Selling Shareholder, for the purpose of
                 further delivery pursuant to this Agreement.  Such Selling
                 Shareholder agrees that the Selling Shareholder Shares to be
                 sold by such Selling Shareholder on deposit with the Custodian
                 are subject to the interests of the Company and the
                 Underwriters, that the arrangements made for such custody are

                 Selling Shareholder hereunder and under the Custody Agreement
                 shall not be terminated except as provided in this Agreement
                 or the Custody Agreement by any act of such Selling
                 Shareholder, by operation of law, whether by the death or
                 incapacity of such Selling Shareholder, or by the occurrence
                 of any other event.  If such Selling Shareholder should die or
                 become incapacitated, or if any other event should occur
                 before the delivery of the Selling Shareholder Shares
                 hereunder, the documents evidencing the Selling Shareholder
                 Shares then on deposit with the Custodian shall be delivered
                 by the Custodian in accordance with the terms and conditions
                 of this Agreement as if such death, incapacity or other event
                 had not occurred, regardless of whether or not the Custodian
                 shall have received notice thereof.

                           (ii)   Such Selling Shareholder has all requisite
                 power and authority to execute, deliver, and perform this
                 Agreement, the Power of Attorney and the Custody Agreement.

                 license, certificate, or permit of or from, or declaration or
                 filing with, any federal, state, local or other governmental
                 authority or any court or other tribunal is required by such
                 Selling Shareholder for the execution, delivery or performance
                 of this Agreement, the Power of Attorney or the Custody
                 Agreement (except filings under the Act which have been made
                 before the applicable Closing Date and such consents
                 consisting only of consents under "blue sky" or securities
                 laws which have been obtained at or prior to the date of this
                 Agreement) by such Selling Shareholder.  No consent of any
                 party to any contract, agreement, instrument, lease, license,
                 indenture, mortgage, deed of trust, note, arrangement or
                 understanding to which such Selling Shareholder is a party, or
                 to which any of such Selling Shareholder's properties or
                 assets are subject, is required for the execution, delivery or
                 performance of this Agreement, the Power of Attorney or the
                 Custody Agreement; and the execution, delivery and performance
                 of this Agreement, the Power of Attorney and the Custody
                 Agreement will not violate, result in a breach of, conflict
                 with, or (with or without the giving of notice of the passage
                 of time or both) entitle any party to terminate or call a
                 default under any such contract, agreement, instrument, lease,

                 conflict with, any law, rule, regulation, order, judgment or
                 decree binding on such Selling Shareholder.

                          (iii)   Such Selling Shareholder has good title to
                 the Selling Shareholder Shares to be sold by such Selling
                 Shareholder pursuant to this Agreement, free and clear of all
                 liens, security interests, pledges, charges, encumbrances,
                 shareholders' agreements and voting trusts subject, in the
                 case of each Selling Shareholder to the rights of Harris Trust

                 accordance with this Agreement, the Underwriters will receive
                 good title to the Selling Shareholder Shares purchased by
                 them, respectively, from such Selling Shareholder, free and
                 clear of all liens, security interests, pledges, charges,
                 encumbrances, shareholders' agreements and voting trusts.

                 governmental or other proceeding (formal or informal), or
                 investigation pending or threatened (or any basis therefor
                 known to such Selling Shareholder) with respect to such
                 Selling Shareholder or his, her or its assets that would have
                 an adverse effect on such Selling Shareholder's ability to
                 perform his, her or its obligations under this Agreement, the
                 Custody Agreement or the Power of Attorney.  Such Selling
                 Shareholder is not in violation of, or in default with respect
                 to, any law, rule, regulation, order, judgment, or decree that
                 would have an adverse effect on such Selling Shareholder's
                 ability to perform his, her or its obligations under this
                 Agreement, the Custody Agreement or the Power of Attorney; nor
                 is such Selling Shareholder required to take any action in
                 order to avoid such a violation or default.

                            (v)   Neither such Selling Shareholder nor any of
                 such Selling Shareholder's affiliates (as defined in the
                 Regulations) has taken or will take, directly or indirectly,
                 prior to the termination of the underwriting syndicate
                 contemplated by this Agreement, any action designed to
                 stabilize or manipulate the price of any security of the
                 Company, or which has caused or resulted in, or which might in
                 the future reasonably be expected to cause or result in,
                 stabilization or manipulation of the price of any security of
                 the Company, to facilitate the sale or resale of any of such
                 Selling Shareholder Shares.

                           (vi)   All information furnished or to be furnished
                 to the Company by or on behalf of such Selling Shareholder for
                 use in connection with the preparation of the Registration
                 Statement and the Prospectus is true in all respects and does
                 not and will not include any untrue statement of a material
                 fact or omit to state any material fact required to be stated
                 therein or necessary to make the statements therein not
                 misleading.

                 such Selling Shareholder has not incurred any liability for a
                 fee, commission or other compensation on account of the
                 employment of a broker or finder in connection with the
                 transactions contemplated by this Agreement.

                         (viii)   Such Selling Shareholder has no knowledge
                 that, and does not believe that, any representation or
                 warranty of the Company in Section 4(a) is incorrect.

                           (ix)   The Selling Shareholder Shares to be sold by
                 such Selling Shareholder pursuant to this Agreement are duly
                 and validly authorized and issued, fully paid and
                 non-assessable, and have not been issued and are not owned or
                 held in violation of any preemptive right of shareholders,
                 optionholders, warrantholders or other persons.

                            (x)   No transaction has occurred between such
                 Selling Shareholder and the Company that is required to be
                 described in the Registration Statement or the Prospectus and

                 the Prospectus.

                 indirectly:  used any corporate funds for unlawful
                 contributions, gifts, entertainment, or other unlawful
                 expenses relating to political activity; made any unlawful

                 material fact or omit to state any material fact necessary to
                 make the statements therein in the light of the circumstances
                 under which they were made not misleading, or if it shall be
                 necessary to amend or supplement the Prospectus to comply with
                 the Act or the Regulations, the Company promptly shall prepare
                 and file with the Commission, subject to the third sentence of
                 paragraph (i) of this Section 6(a), an amendment or supplement
                 which shall correct such statement or omission or an amendment
                 which shall effect such compliance.

                          (iii)   The Company shall make generally available to
                 its security holders and to the Representatives as soon as
                 practicable, but not later than 45 days after the end of the
                 12-month period beginning at the end of the fiscal quarter of
                 the Company during which the Effective Date occurs (or 90 days
                 if such 12-month period coincides with the Company's fiscal
                 year), an earnings statement (which need not be audited) of
                 the Company, covering such 12-month period, which shall
                 satisfy the provisions of Section 11(a) of the Act or Rule 158
                 of the Regulations.

                           (iv)   The Company shall furnish the Representatives
                 and counsel for the Underwriters, without charge, signed
                 copies of the Registration Statement (including all exhibits
                 thereto, Incorporated Documents and amendments thereto) and to
                 each other Underwriter a copy of the Registration Statement
                 (without exhibits thereto or Incorporated Documents) and all
                 amendments thereof and, so long as delivery of a prospectus by
                 an Underwriter or dealer may be required by the Act or the
                 Regulations, as many copies of any Preliminary Prospectus and
                 the Prospectus and any amendments thereof and supplements
                 thereto as the Representatives may reasonably request.

                            (v)   The Company shall cooperate with the
                 Representatives and their counsel in endeavoring to qualify
                 the Shares for offer and sale under the laws of such
                 jurisdictions as the Representatives may designate and shall
                 maintain such qualifications in effect so long as required for
                 the distribution of the Shares; provided, however, that the
                 Company shall not be required in connection therewith, as a
                 condition thereof, to qualify as a foreign corporation or to
                 execute a general consent to service of process in any
                 jurisdiction or subject itself to taxation as doing business
                 in any jurisdiction.

                           (vi)   For a period of five years after the date of
                 this Agreement, the Company shall supply to each of the
                 Representatives, and to each other Underwriter who may so
                 request in writing, copies of such financial statements and
                 other periodic and special reports as the Company may from
                 time to time distribute generally to the holders of any class
                 of its capital stock and to furnish to each of the
                 Representatives a copy of each annual, quarterly or other
                 report it shall be required to file with the Commission.

                          (vii)   Without the prior written consent of the
                 Representatives, for a period of 180 days from the date on
                 which a public offering of the Shares commences, the Company
                 shall not issue, sell or register with the Commission or
                 otherwise dispose of, directly or indirectly, any securities
                 of the Company (or any securities convertible into or
                 exercisable or exchangeable for securities of the Company),
                 except for the issuance of the Shares pursuant to the
                 Registration Statement.

                         (viii)   On or before completion of this offering, the
                 Company shall make all filings required under applicable
                 securities laws and by the NASDAQ National Market.

                           (ix)   Prior to each Closing Date and for a period
                 of 25 days thereafter, you shall be given reasonable written
                 prior notice of any press release or other direct or indirect
                 communication and of any press conference with respect to the
                 Company, the financial conditions, results of operations
                 business, properties, assets, liabilities of the Company, or
                 this offering.

                            (x)   The Company will apply the net proceeds from
                 the Offering received by it in the manner set forth under the
                 caption "Use of Proceeds" in the Prospectus.

                 (b)     The Company agrees to pay, or reimburse if paid by the
         Representatives, whether or not the transactions contemplated hereby
         are consummated or this Agreement is terminated, all costs and
         expenses relating to the registration and public offering of the
         Shares including those relating to: (i) the preparation, printing,
         filing and distribution of the Registration Statement including all
         exhibits thereto, each Preliminary Prospectus, the Prospectus, all
         amendments and supplements to the Registration Statement and the
         Prospectus, and any documents required to be delivered with any
         Preliminary Prospectus or the Prospectus, and the printing, filing and
         distribution of the Agreement Among Underwriters, this Agreement and
         related documents; (ii) the preparation and delivery of certificates
         for the Shares to the Underwriters; (iii) the registration or
         qualification of the Shares for offer and sale under the securities or
         Blue Sky laws of the various jurisdictions referred to in Section
         6(a)(v), including the fees and disbursements of counsel for the
         Underwriters in connection with such registration and qualification
         and the preparation, printing, distribution and shipment of
         preliminary and supplementary Blue Sky memoranda; (iv) the furnishing
         (including costs of shipping and mailing) to the Representatives and
         to the Underwriters of copies of each Preliminary Prospectus, the
         Prospectus and all amendments or supplements to the Prospectus, and of
         the several documents required by this Section to be so furnished, as
         may be reasonably requested for use in connection with the offering
         and sale of the Shares by the Underwriters or by dealers to whom
         Shares may be sold; (v) the filing fees of the NASD in connection with
         its review of the terms of the public offering; (vi) the furnishing
         (including costs of shipping and mailing) to the Representatives and
         to the Underwriters of copies of all reports and information required
         by Section 6(a)(vi); (vii) inclusion of the Shares for quotation on
         the NASDAQ National Market System; and (viii) all transfer taxes, if
         any, with respect to the sale and delivery of the Shares by the
         Company and the Selling Shareholders to the Underwriters.  Except as
         otherwise contemplated by Section 9 hereof, the Underwriters will pay
         their own counsel fees and expenses to the extent not otherwise
         covered by clause (iii) above, and their own travel and travel-related
         expenses in connection with the distribution of the Shares.  Without
         limiting the Company's obligations set forth above, each of the
         Selling Shareholders agrees to pay all of the other costs and expenses
         incident to the





                                       20
<PAGE>   21
         performance of its obligations under this Agreement and the sale of
         the Selling Shareholder Shares by them hereunder.

         7.      Indemnification.

                 (a)     The Company agrees to indemnify and hold harmless each
         Underwriter and each person, if any, who controls any Underwriter
         within the meaning of Section 15 of the Act or Section 20 of the
         Exchange Act against any and all losses, claims, damages and
         liabilities, joint or several (including any reasonable investigation,
         legal and other expenses incurred in connection with, and any amount
         paid in settlement of, any action, suit or proceeding or any claim
         asserted), to which they, or any of them, may become subject under the
         Act, the Exchange Act or other Federal or state law or regulation, at
         common law or otherwise, insofar as such losses, claims, damages or
         liabilities arise out of or are based upon any untrue statement or
         alleged untrue statement of a material fact contained in any
         Preliminary Prospectus, the Registration Statement or other Prospectus
         or any amendment thereof or supplement thereto, or arise out of or are
         based upon any omission or alleged omission to state therein such fact
         required to be stated therein or necessary to make such statements
         therein not misleading.  The Selling Shareholders agree, jointly and
         severally, to indemnify each Underwriter and each person, if any, who
         controls any Underwriter within the meaning of Section 15 of the Act
         or Section 20 of the Exchange Act, against any and all losses, claims,
         damages and liabilities, joint or several (including any reasonable
         investigation, legal and other expenses incurred in connection with,
         and any amount paid in settlement of, any action, suit or proceeding
         or any claim asserted), to which they, or any of them, may become
         subject under the Act, the Exchange Act or other Federal or state law
         or regulation, at common law or otherwise, insofar as such losses,
         claims, damages or liabilities arise out of or are based upon any
         untrue statement or alleged untrue statement of a material fact with
         respect to such Selling Shareholders contained in any Preliminary
         Prospectus, the Registration Statement or the Prospectus or any
         amendment thereof or supplement thereto (which amendments or
         supplements are furnished to such Selling Shareholders), or which
         arise out of or are based upon any omission or alleged omission to
         state therein such fact required to be stated therein or necessary to
         make such statements therein not misleading, but only with reference
         to information relating to such Selling Shareholders furnished in
         writing to the Company by or on behalf of such Selling Shareholders
         expressly for use in connection with the preparation of the
         Registration Statement and Prospectus or any amendment thereof or
         supplement thereto.  Such indemnity shall not inure to the benefit of
         any Underwriter (or any person controlling such Underwriter) on
         account of any losses, claims, damages or liabilities arising from the
         sale of the Shares to any person by such Underwriter if such untrue
         statement or omission or alleged untrue statement or omission was made
         in such Preliminary Prospectus, the Registration Statement or the
         Prospectus, or such amendment or supplement, in reliance upon and in
         conformity with information furnished in writing to the Company by the
         Representatives on behalf of any Underwriter specifically for use
         therein.  The obligations of each of the Selling Shareholders,
         pursuant to this Section 7(a) and Section 8, shall be limited to an
         amount not exceeding the product of the Per Share Price to Public of
         the Shares as set forth on the cover page of the Prospectus and the
         number of Selling Shareholder Shares being sold by each of them.  In
         no event shall the indemnification agreement contained in this Section
         7(a) inure to the benefit of any Underwriter on account of any losses,
         claims, damages, liabilities or actions arising from the sale of the
         Shares upon the public offering to any person by such Underwriter if
         such losses, claims, damages, liabilities or actions arise out of, or
         are based upon, a statement or omission or alleged





                                       21
<PAGE>   22
         omission in a Preliminary Prospectus and if, in respect to such
         statement, omission or alleged omission, the Prospectus differs in a
         material respect from such Preliminary Prospectus and a copy of the
         Prospectus has not been sent or given to such person at or prior to
         the confirmation of such sale to such person.  This indemnity
         agreement will be in addition to any liability which the Company and
         the Selling Shareholders may otherwise have.

                 (b)     Each Underwriter agrees, severally and not jointly, to
         indemnify and hold harmless the Company, each person, if any, who
         controls the Company within the meaning of Section 15 of the Act or
         Section 20 of the Exchange Act, each director of the Company, and each
         officer of the Company who signs the Registration Statement and each
         Selling Shareholder, to the same extent as the foregoing indemnity
         from the Company and the Selling Shareholders to each Underwriter, but
         only insofar as such losses, claims, damages or liabilities arise out
         of or are based upon any untrue statement or omission or alleged
         untrue statement or omission which was made in any Preliminary
         Prospectus, any Rule 430A Prospectus, the Registration Statement or
         the Prospectus, or any amendment thereof or supplement thereto, which
         were made in reliance upon and in conformity with information
         furnished in writing to the Company by the Representatives on behalf
         of any Underwriter for specific use therein; provided, however, that
         the obligation of each Underwriter to indemnify the Company (including
         any controlling person, director or officer thereof) and the Selling
         Shareholders shall be limited to the net proceeds received by the
         Company and the Selling Shareholders, respectively, from such
         Underwriter.  For all purposes of this Agreement, the amounts of the
         selling concession and reallowance set forth in the Prospectus
         constitute the only information furnished in writing by or on behalf
         of any Underwriter expressly for inclusion in any Preliminary
         Prospectus, any Rule 430A Prospectus, the Registration Statement or
         the Prospectus or any amendment or supplement thereto.

                 (c)     Any party that proposes to assert the right to be
         indemnified under this Section 7 will, promptly after receipt of
         notice of commencement of any action, suit or proceeding against such
         party in respect of which a claim is to be made against an
         indemnifying party or parties under this Section, notify each such
         indemnifying party of the commencement of such action, suit or
         proceeding, enclosing a copy of all papers served.  No indemnification
         provided for in Section 7(a) or 7(b) shall be available to any party
         who shall fail to give notice as provided in this Section 7(c) if the
         party to whom notice was not given was unaware of the proceeding to
         which such notice would have related and was prejudiced by the failure
         to give such notice but the omission so to notify such indemnifying
         party of any such action, suit or proceeding shall not relieve it from
         any liability that it may have to any indemnified party for
         contribution or otherwise than under this Section.  In case any such
         action, suit or proceeding shall be brought against any indemnified
         party and it shall notify the indemnifying party of the commencement
         thereof, the indemnifying party shall be entitled to participate in,
         and, to the extent that it shall wish, jointly with any other
         indemnifying party similarly notified, to assume the defense thereof,
         with counsel reasonably satisfactory to such indemnified party, and
         after notice from the indemnifying party to such indemnified party of
         its election so to assume the defense thereof and the approval by the
         indemnified party of such counsel, the indemnifying party shall not be
         liable to such indemnified party for any legal or other expenses,
         except as provided below and except for the reasonable costs of
         investigation subsequently incurred by such indemnified party in
         connection with the defense thereof.  The indemnified party shall have
         the right to employ its counsel in any such action, but the fees and
         expenses of such counsel shall be at the expense of such indemnified
         party unless (i) the employment of counsel by such indemnified party
         has been





                                       22
<PAGE>   23
         authorized in writing by the indemnifying parties, (ii) the
         indemnified party shall have reasonably concluded that there may be a
         conflict of interest between the indemnifying parties and the
         indemnified party in the conduct of the defense of such action (in
         which case the indemnifying parties shall not have the right to direct
         the defense of such action on behalf of the indemnified party), or
         (iii) the indemnifying parties shall not have employed counsel to
         assume the defense of such action within a reasonable time after
         notice of the commencement thereof, in each of which cases the
         reasonable fees and expenses of counsel shall be at the expense of the
         indemnifying parties.  An indemnifying party shall not be liable for
         any settlement of any action, suit, proceeding or claim effected
         without its written consent.

         8.      Contribution.  In order to provide for just and equitable
contribution in circumstances in which the indemnification provided for in
Sections 7(a) and (b) is due in accordance with its terms but for any reason is
held to be unavailable from the Company, the Selling Shareholders or the
Underwriters, the Company, the Selling Shareholders and the Underwriters shall
contribute to the aggregate losses, claims, damages and liabilities (including
any investigation, legal and other expenses reasonably incurred in connection
with, and any amount paid in settlement of, any action, suit or proceeding or
any claims asserted, but after deducting any contribution received by the
Company from persons other than the Underwriters, such as the Selling
Shareholders, persons who control the Company within the meaning of the Act,
officers of the Company who signed the Registration Statement and directors of
the Company, who may also be liable for contribution) to which the Company and
the Selling Shareholders and one or more of the Underwriters may be subject in
such proportion as is appropriate to reflect the relative benefits received by
the Company and the Selling Shareholders on the one hand and the Underwriters
on the other from the offering of the Shares or, if such allocation is not
permitted by applicable law or indemnification is not available as a result of
the indemnifying party not having received notice as provided in Section 7
hereof, in such proportion as is appropriate to reflect not only the relative
benefits referred to above but also the relative fault of the Company and the
Selling Shareholders on the one hand and the Underwriters on the other 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 benefits received by the Company, the
Selling Shareholders and the Underwriters shall be deemed to be in the same
proportion as (x) the total proceeds from the Offering (net of underwriting
discounts but before deducting expenses) received by the Company or the Selling
Shareholders from the sale of the Shares, as set forth in the table on the
cover page of the Prospectus (but not taking into account the use of the
proceeds of such sale of Shares by the Company), bear to (y) the underwriting
discount received by the Underwriters, as set forth in the table on the cover
page of the Prospectus.  The relative fault of the Company, the Selling
Shareholders and the Underwriters shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
related to information supplied by the Company, the Selling Shareholders or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.  The Company,
the Selling Shareholders and the Underwriters agree that it would not be just
and equitable if contribution pursuant to this Section 8 were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of
the equitable considerations referred to above.  Notwithstanding the provisions
of this Section 8, (i) in no case shall any Underwriter (except as may be
provided in the Agreement Among Underwriters) be liable or responsible for any
amount in excess of the underwriting discount applicable to the Shares purchase
by such Underwriter hereunder, (ii) in no case shall any of the Selling
Shareholders be liable or responsible for any amount in excess of the product
of the Per Share Price to Public of the Shares as set forth on the cover page
of the Prospectus and the number of Shares being sold





                                       23
<PAGE>   24
by each of them subject to the limitation expressed in Section 7(a), and (iii)
the Company shall be liable and responsible for any amount in excess of the
underwriting discount and the amount referred to in clause (ii); provided,
however (i) that no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.  For purpose of
this Section 8, each person, if any, who controls an Underwriter within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act shall
have the same rights to contribution as such Underwriter, and each person, if
any, who controls the Company within the meaning of the Section 15 of the Act
or Section 20(a) of the Exchange Act, each officer of the Company who shall
have signed the Registration Statement and each director of the Company shall
have the same rights to contribution as the Company, subject in each case to
clauses (i), (ii) and (iii) in the immediately preceding sentence of this
Section 8.  Any party entitled to contribution will, promptly after receipt of
notice of commencement of any action, suit or proceeding against such party in
respect of which a claim for contribution may be made against another party or
parties under this Section, notify such party or parties from whom contribution
may be sought, but the omissions so to notify such party or parties from whom
contribution may be sought shall not relieve the party or parties from whom
contribution may be sought from any other obligation it or they may have
hereunder or otherwise than under this Section.  No party shall be liable for
contribution with respect to any action, suit, proceeding or claim settled
without its written consent.  The Underwriters' obligations to contribute
pursuant to this Section 8 are several in proportion to their respective
underwriting commitments and not joint.

         9.      Termination.  This Agreement may be terminated with respect to
the Shares to be purchased on any Closing Date by the Representatives by
notifying the Company at any time prior to the purchase of the Shares:

                 (a)     in the absolute discretion of the Representatives at
         or before any Closing Date: (i) if on or prior to such date, any
         domestic or international event or act or occurrence has materially
         disrupted, or in the opinion of the Representatives will in the future
         materially disrupt, the securities markets; (ii) if there has occurred
         any new outbreak or material escalation of hostilities or other
         calamity or crisis the effect of which on the financial markets of the
         United States is such as to make it, in the judgment of the
         Representatives, inadvisable to proceed with the Offering; (iii) if
         there shall be such a material adverse change in general financial,
         political or economic conditions or the effect of international
         conditions on the financial markets in the United States such as to
         make it, in the judgment of the Representatives, inadvisable or
         impracticable to market the Shares; (iv) if trading in the Shares has
         been suspended by the Commission or trading generally on the New York
         Stock Exchange, Inc., the American Stock Exchange, Inc. or the NASDAQ
         National Market has been suspended or limited, or minimum or maximum
         ranges for prices for securities shall have been fixed, or maximum
         ranges for prices for securities have been required, by said exchanges
         or by order of the Commission, the NASD, or any other governmental or
         regulatory authority; or (v) if a banking moratorium has been declared
         by any state or federal authority, or

                 (b)     at or before any Closing Date, if any of the
         conditions specified in Section 5 shall not have been fulfilled when
         and as required by this Agreement.

         If this Agreement is terminated pursuant to any of its provisions,
neither the Company nor any of the Selling Shareholders shall be under any
liability to any Underwriter, and no Underwriter shall be





                                       24
<PAGE>   25
under any liability to the Company or any the Selling Shareholders, except that
(y) if this Agreement is terminated by the Representatives or the Underwriters
because of any failure, refusal or inability on the part of the Company or the
Selling Shareholders or all of them to comply with the terms or to fulfill any
of the conditions of this Agreement, the Company and each of the Selling
Shareholders will reimburse the Underwriters for all out-of-pocket expenses
(including the fees and disbursements of their counsel) incurred by them in
connection with the proposed purchase and sale of the Shares or in
contemplation of performing their obligations hereunder and (z) no Underwriter
who shall have failed or refused to purchase the Shares agreed to be purchased
by it under this Agreement, without some reason sufficient hereunder to justify
cancellation or termination of its obligations under this Agreement, shall be
relieved of liability to the Company and any the Selling Shareholders or to the
other Underwriters for damages occasioned by its failure or refusal.

         10.     Substitution of Underwriters.  If one or more of the
Underwriters shall fail (other than for a reason sufficient to justify the
cancellation or termination of this Agreement under Section 9) to purchase on
any Closing Date the Shares agreed to be purchased on such Closing Date by such
Underwriter or Underwriters, the Representatives may find one or more
substitute underwriters to purchase such Shares or make such other arrangements
as the Representatives may deem advisable or one or more of the remaining
Underwriters may agree to purchase such Shares in such proportions as may be
approved by the Representatives, in each case upon the terms set forth in this
Agreement.  If no such arrangements have been made by the close of business on
the business day following such Closing Date:

                 (a)     if the number of Shares to be purchased by the
         defaulting Underwriters on such Closing Date shall not exceed 10% of
         the Shares that all the Underwriters are obligated to purchase on such
         Closing Date, then each of the nondefaulting Underwriters shall be
         obligated to purchase such Shares on the terms herein set forth in
         proportion to their respective obligations hereunder; provided, that
         in no event shall the maximum number of Shares that any Underwriter
         has agreed to purchase pursuant to Section 1 be increased pursuant to
         this Section 10 by more than one-ninth of such number of Shares
         without the written consent of such Underwriter, or

                 (b)     if the number of Shares to be purchased by the
         defaulting Underwriters on such Closing Date shall exceed 10% of the
         Shares that all the Underwriters are obligated to purchase on such
         Closing Date, then the Company shall be entitled to an additional
         business day within which it may, but is not obligated to, find one or
         more substitute underwriters reasonably satisfactory to the
         Representatives to purchase such Shares upon the terms set forth in
         this Agreement.

         In any such case, either the Representatives or the Company shall have
the right to postpone the applicable Closing Date for a period of not more than
five business days in order that necessary changes and arrangements (including
any necessary amendments or supplements to the Registration Statement or
Prospectus) may be effected by the Representatives and the Company.  If the
number of Shares to be purchased on such Closing Date by such defaulting
Underwriter or Underwriters shall exceed 10% of the Shares that all the
Underwriters are obligated to purchase on such Closing Date, and none of the
nondefaulting Underwriters or the Company shall make arrangements pursuant to
this Section within the period stated for the purchase of the Shares that the
defaulting Underwriters agreed to purchase, this Agreement shall terminate with
respect to the Shares to be purchased on such Closing Date without liability on
the part of any nondefaulting Underwriter to the Company and the Selling
Shareholders and without liability on the part of the Company and the Selling
Shareholders, except in both cases as





                                       25
<PAGE>   26
provided in Sections 6(b), 7, 8 and 9.  The provisions of this Section shall
not in any way affect the liability of any defaulting Underwriter to the
Company or the Selling Shareholders or the nondefaulting Underwriters arising
out of such default.  A substitute underwriter hereunder shall become an
Underwriter for all purposes of this Agreement.

         11.     Miscellaneous.  The respective agreements, representations,
warranties, indemnities and other statements of the Company or its officers, of
the Selling Shareholders and of the Underwriters set forth in or made pursuant
to this Agreement shall remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the Selling Shareholders or any of the officers, directors or controlling
persons referred to in Sections 7 and 8 hereof, and shall survive deliver of
and payment for the Shares.  The provisions of Sections 6(b), 7, 8 and 9 shall
survive the termination or cancellation of this Agreement.

         This Agreement has been and is made for the benefit of the
Underwriters, the Company and the Selling Shareholders and their respective
successors and assigns and, to the extent expressed herein, for the benefit of

officers of the Company, and their respective successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement.  The term "successors and assigns" shall not include any purchaser
of Shares from any Underwriter merely because of such purchase.

         All notices and communications hereunder shall be in writing and

                                   EXHIBIT A
     
             [Legal opinion of Jordaan, Howard & Pennington, PLLC]


                         (i)      Each of the Company and the Texas
                 Subsidiaries is a corporation duly organized, validly
                 existing, and in good standing under the laws of the State of
                 Texas with full corporate power and authority to own, lease,
                 license and use its properties and assets and to conduct its
                 business in the manner described in the Prospectus.  To the
                 knowledge of such counsel, the Company has all necessary
                 consents, authorizations, approvals, orders, certificates and
                 permits of and from, and declarations and filings with, all
                 federal, state, local and other governmental authorities and
                 all courts and other tribunals, to own, lease, license and use
                 its properties and assets and to conduct its business in the
                 manner described in the Prospectus.  Each of the Company and
                 the Texas Subsidiaries is duly qualified to do business and is
                 in good standing, in each state where the failure to be so
                 qualified could have a material adverse effect on the
                 operating condition (financial and otherwise) or business of
                 the Company.  The Company has no subsidiaries and does not
                 control, directly or indirectly, any corporation, partnership,
                 joint venture, association or other business organization,
                 except for the Subsidiaries as defined in Section 4(a)(v) of
                 this Agreement.

                         (ii)     The Company has authorized, issued and
                 outstanding capital stock as set forth under the caption
                 "Capitalization" in the Prospectus.  The certificates
                 evidencing the shares are in due and proper legal form.  Each
                 outstanding share of Common Stock has been duly and validly
                 authorized and issued, fully paid, and non-assessable, without
                 any personal liability attaching to the ownership thereof, and
                 has not been issued and is not owned or held in violation of
                 any preemptive right of shareholders.  The Company owns all of
                 the shares of capital stock of the Subsidiaries, free and
                 clear of all liens, claims, security interests, restrictions,
                 shareholders' agreements, voting trusts and any other
                 encumbrances whatsoever.  To the knowledge of such counsel,
                 there is no commitment, plan, or arrangement to issue, and no
                 outstanding option, warrant, or other right calling for the
                 issuance of, any share of capital stock of the Company or any
                 of the Subsidiaries or any security or other instrument which
                 by its terms is convertible into, exercisable for, or
                 exchangeable for capital stock of the Company or any of the
                 Subsidiaries, except as properly described in the Prospectus.
                 To the knowledge of such counsel, there is outstanding no
                 security or other instrument which by its terms is convertible
                 into, exercisable for or exchangeable for capital stock of the
                 Company or any of the Subsidiaries, except as may be properly
                 described in the Prospectus.

                         (iii)    There is no litigation, arbitration, claim,
                 governmental or other proceeding (formal or informal), or
                 investigation before any court or before any public body or
                 board pending, or to the knowledge of such counsel, threatened
                 with respect to the Company, the Subsidiaries, the Selling
                 Shareholders or any of their respective operations,
                 businesses, properties, assets, or financial condition except
                 as properly described in the Prospectus or such as
                 individually or in the aggregate do not now have and are not
                 in the future reasonably foreseeable to have a material
                 adverse effect upon the operations, business, properties,
                 assets, or financial condition of the Company and the
                 Subsidiaries.  To the knowledge of such counsel, neither the
                 Company nor the





                                      A-1
<PAGE>   31
                 Subsidiaries is involved in any labor dispute, nor is such
                 dispute threatened, which dispute would have a material
                 adverse effect upon the operations, business, properties,
                 assets or financial condition of the Company and the
                 Subsidiaries.  Neither the Company nor any of the Texas
                 Subsidiaries are in violation of, or in default with respect
                 to, any law, rule, regulation, order, judgment, or decree,
                 except as may be properly described in the Prospectus or such
                 as in the aggregate do not now have and will not in the future
                 have a material adverse effect upon the operations, business,
                 properties, assets, or financial condition of the Company or
                 the Subsidiaries; nor is the Company or any of the Texas
                 Subsidiaries required to take any action in order to avoid any
                 such violation or default.

                         (iv)     To the knowledge of such counsel, neither the
                 Company the Subsidiaries nor any other party is now or is
                 expected by the Company to be in violation or breach of, or in
                 default with respect to, complying with any term, obligation
                 or provision of any contract, agreement, instrument, lease,
                 license, indenture, mortgage, deed of trust, note, arrangement
                 or understanding which is material to the Company or any of
                 the Subsidiaries or by which any of their respective
                 properties or businesses may be bound or affected and no event
                 has occurred which with notice or lapse of time or both would
                 constitute such a default.

                         (v)      Neither the Company nor any of the Texas
                 Subsidiaries is in violation or breach of, or in default with
                 respect to, any term of its certificate of incorporation (or
                 other charter document) or by-laws.

                         (vi)     Each of the Company and the Texas
                 Subsidiaries has all requisite power and authority to execute,
                 deliver and perform this Agreement and to issue and sell the
                 Shares.  All necessary corporate proceedings of the Company
                 and the Subsidiaries have been taken to authorize the
                 execution, delivery and performance by the Company of this
                 Agreement.  This Agreement has been duly authorized, executed
                 and delivered by each of the Company and the Subsidiaries, is
                 the legal, valid and binding obligation of each of the Company
                 and of the Texas Subsidiaries and (subject to applicable
                 bankruptcy, insolvency, and other laws affecting the
                 enforceability of creditors' rights generally) is enforceable
                 as to the Company in accordance with its terms.  No consent,
                 authorization, approval, order, license, certificate or permit
                 of or from, or declaration or filing with, any federal state,
                 local or other governmental authority or any court or other
                 tribunal is required by the Company or the Texas Subsidiaries
                 for the execution, delivery or performance by the Company or
                 the Texas Subsidiaries of this Agreement (except filings under
                 the Act which have been made prior to the Closing Date and
                 consents consisting only of consents under "blue sky" or

                 Subsidiaries or the Selling Shareholder are a party, or to

                 incorporation (or other charter document) or by- laws of the
                 Company, or violate, result in a breach of, or conflict with
                 any law, rule, regulation, order, judgement, or decree binding
                 on the Company, or any of the Subsidiaries or to which any of
                 their respective operations, businesses, properties or assets
                 are subject.

                         (vii)    The Firm Shares and the Option Shares are
                 duly and validly authorized.  Each Share, as the case may be,
                 delivered on the Closing Dates is duly and validly issued,
                 fully paid, and non- assessable, with no personal liability
                 attaching to the ownership thereof, and is not issued in
                 violation of any preemptive rights of shareholders, and the
                 Underwriters have received good title to the Shares purchased
                 by them, respectively, from the Company and the Selling
                 Shareholder, as applicable, for the consideration contemplated
                 herein and in good faith and without notice of any adverse
                 claim within the meaning of the Uniform Commercial Code, free
                 and clear of any liens, security interests, pledges, charges,
                 encumbrances, stockholders' agreements, voting trusts and
                 other claims.  The Common Stock, the Firm Shares and the
                 Option Shares conform to all statements relating thereto
                 contained in the Registration Statement or the Prospectus and
                 are approved for listing on the Nasdaq National Market.

                         (viii)   To the knowledge of such counsel, any
                 contract, agreement, instrument, lease or license required to
                 be described in the Registration Statement or the Prospectus
                 has been properly described therein.  To the knowledge of such
                 counsel, any contract, agreement, instrument, lease or license
                 required to be filed as an exhibit to the Registration
                 Statement has been filed with the Commission as an exhibit to
                 or has been incorporated as an exhibit by reference into the
                 Registration Statement.

                         (ix)     Insofar as statements in the Prospectus
                 purport to summarize the status of litigation or the
                 provisions of laws, rules, regulations, orders, judgments,
                 decrees, contracts, agreements, instruments, leases or
                 licenses, such statements have been prepared or reviewed by
                 such counsel and to the knowledge of such counsel, accurately
                 reflect the status of such litigation and provisions purported
                 to be summarized and are correct in all material respects.

                         (x)      The Company is not required and will not be
                 required as a result of this offering, to be registered as an
                 "investment company" under the Investment Company Act of 1940,
                 as amended.

                         (xi)     To the knowledge of such counsel, no person
                 or entity has the right to require registration of shares of
                 Common Stock or other securities of the Company because of the
                 filing or effectiveness of the Registration Statement except
                 such persons or entities from whom written waivers of such
                 rights have been received prior to the Closing Date.

                         (xii)    The Registration Statement has become
                 effective under the Act.  No Stop Order has been issued and no
                 proceedings for that purpose has been instituted or are
                 threatened, pending, or to such counsel's knowledge,
                 contemplated.

                         (xiii)   The Registration Statement, any Rule 430A
                 Prospectus, and the Prospectus, and any amendment or
                 supplement thereto (other than financial statements and other
                 financial data and schedules which are or should be contained
                 in any thereof, as to which such counsel need express no
                 opinion), comply as to form in all material respects with the
                 requirements of the Act and the Regulations.  To the knowledge
                 of such counsel, the conditions for the use of Form S-1 have
                 been satisfied with respect to the Registration Statement.

                         (xiv)    To the knowledge of such counsel, since the
                 effective date of the Registration Statement, no event has
                 occurred which should have been set forth in an amendment or
                 supplement to the Registration Statement or the Prospectus
                 which has not been set forth in such an amendment or
                 supplement.

                         (xv)     The agreement of each officer and director of
                 the Company and the Selling Shareholders, stating that for a
                 period of 180 days from the date on which the public offering
                 of the Shares commences, such party will not, without the
                 Representatives' prior written consent, offer, pledge, sell,
                 contract to sell, grant any option for the sale of, or
                 otherwise dispose of, directly or indirectly, any shares of
                 Common Stock (or any other securities of the Company or any
                 security or other instrument which by its terms is convertible
                 into, exercisable for, or exchangeable for shares of Common
                 Stock or other securities of the Company, including, without
                 limitation, any shares of Common Stock issuable under any
                 employee stock options), beneficially owned by such party, has
                 been duly and validly authorized, executed and delivered by
                 such party and constitutes the legal, valid and binding
                 obligation of such party enforceable against such party in
                 accordance with its terms.

         In addition, counsel has participated in the preparation of the
Registration Statement and the Prospectus and in conferences with officers and
other representative of the Company, representatives of the Representatives and
representatives of the independent accountants of the Company, at which
conferences the contents of the Registration Statement and the Prospectus and
related matters were discussed and, although such counsel has not independently
verified and is not passing upon and does not assume any responsibility for the
accuracy, completeness or fairness of the statements contained in the
Registration Statement and the Prospectus (except as specified in the foregoing
opinion), on the basis of the foregoing and relying as to materiality upon the
representations of executive officers of the Company after conferring with such
executive officers, no facts have come to the attention of such counsel which
lead such counsel to believe that the Registration Statement at the time it
became effective and at each Closing Date contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading, or that the
Prospectus, except for the financial statements and other financial and
statistical data included therein as to which counsel need express no opinion,
as amended or supplemented on the date thereof and at each Closing Date
contained any untrue statement of a material fact or omitted to state a
material fact necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading (it being
understood that such counsel need express no comment with respect to the
financial statements and schedules and other financial or statistical data
included in the Registration Statement or Prospectus).

          [Legal opinion of Margain - Rojas - Gonzalez - Vargas, S.C.]

                         (i)  Each Mexican Subsidiary is a corporation duly
                 organized, validly existing, and in good standing under the
                 laws of the State of its incorporation, with full corporate
                 power and authority to own, lease, license and use its
                 properties and assets and to conduct its business in the
                 manner described in the Prospectus.  To the knowledge of such
                 counsel, each of the Mexican Subsidiaries has all necessary
                 consents, authorizations, approvals, orders, certificates and
                 permits of and from, and declarations and filings with, all
                 federal, state, local and other governmental authorities and
                 all courts and other tribunals, to own, lease, license and use
                 its properties and assets and to conduct its business in the
                 manner described in the Prospectus.  Each Mexican Subsidiary
                 is duly qualified to do business and is in good standing, in
                 each state where the failure to be so qualified could have a
                 material adverse effect on the operating condition (financial
                 and otherwise) or business of such Mexican Subsidiary or the
                 Company.

                         (ii)  There is no litigation, arbitration, claim,
                 governmental or other proceeding (formal or informal), or
                 investigation before any court or before any public body or
                 board pending or to the knowledge of such counsel, threatened
                 with respect to the Mexican Subsidiaries or any of their
                 respective operations, businesses, properties, assets, or
                 financial condition except as properly described in the
                 Prospectus or such as individually or in the aggregate do not
                 now have and are not in the future reasonably foreseeable to
                 have a material adverse effect upon the operations, business,
                 properties, assets, or financial condition of the Mexican
                 Subsidiaries.  Neither of the Mexican Subsidiaries is in
                 violation of, or in default with respect to, any law, rule,
                 regulation, order, judgment, or decree, except as may be
                 properly described in the Prospectus or such as in the
                 aggregate do not now have and will not in the future have a
                 material adverse effect upon the operations, business,
                 properties, assets, or financial condition of the Mexican
                 Subsidiaries; nor is either of the Mexican Subsidiaries
                 required to take any action in order to avoid any such
                 violation or default.

                         (iii)  To the knowledge of such counsel, the Mexican
                 Subsidiaries are not now nor is either of them expected by the
                 Company to be in violation or breach of, or in default with
                 respect to, complying with any term, obligation or provision
                 of any contract, agreement, instrument, lease, license,
                 indenture, mortgage, deed of trust, note, arrangement or
                 understanding which is material to the Mexican Subsidiaries or
                 by which any of their respective properties or businesses may
                 be bound or affected and no event has occurred which with
                 notice or lapse of time or both would constitute such a
                 default.

                         (iv)  Neither of the Mexican Subsidiaries is in
                 violation or breach of, or in default with respect to, any
                 term of its certificate of incorporation (or other charter
                 documents)

                         (v)  No consent, authorization, approval, order,
                 license, certificate or permit of or from, or declaration or
                 filing with, any federal state, local or other governmental
                 authority or any court or other tribunal is required by the
                 Mexican Subsidiaries for the execution, delivery or
                 performance of this Agreement (except filings under the Act
                 which have been made prior to the Closing Date and consents
                 consisting only of consents under

                 "blue sky" or securities laws).  To the knowledge of such
                 counsel, no consent of any party to any contract, agreement,
                 instrument, lease, license, indenture, mortgage, deed of trust,
                 note, arrangement or understanding to which the Mexican
                 Subsidiaries are a party, or to which any of their respective
                 properties or assets are subject, is required for the
                 execution, delivery or performance of this Agreement; and the
                 execution, delivery and performance of this Agreement will not
                 violate, result in a breach of, conflict with, or (with or
                 without the giving of notice or the passage of time or both)
                 entitle any party to terminate or call a default under any such
                 contract, agreement, instrument, lease, license, indenture,
                 mortgage, deed of trust, note, arrangement or understanding, in
                 each case known to such counsel, or violate or result in a
                 breach of any term of the certificate of incorporation (or
                 other charter document) or by-laws or violate, result in a
                 breach of, or conflict with any law, rule, regulation, order,
                 judgement, or decree binding on either of the Mexican
                 Subsidiaries or to which any of their respective operations,
                 businesses, properties or assets are subject.

                         (vi)  To the knowledge of such counsel, any contract,
                 agreement, instrument, lease or license required to be
                 described in the Registration Statement or the Prospectus has
                 been properly described therein.

                         (vii)  Insofar as statements in the Prospectus purport
                 to summarize the status of litigation or the provisions of
                 laws, rules, regulations, orders, judgments, decrees,
                 contracts, agreements, instruments, leases or licenses, such
                 statements have been prepared or reviewed by such counsel and
                 to the knowledge of such counsel, accurately reflect the
                 status of such litigation and provisions purported to be
                 summarized and are correct in all material respects.

                         (i)  Deli-Bon is a corporation duly organized, validly
                 existing, and in good standing under the laws of the State of
                 its incorporation, with full corporate power and authority to
                 own, lease, license and use its properties and assets and to
                 conduct its business in the manner described in the
                 Prospectus.  To the knowledge of such counsel, Deli-Bon has
                 all necessary consents, authorizations, approvals, orders,
                 certificates and permits of and from, and declarations and
                 filings with, all federal, state, local and other governmental

                 is duly qualified to do business and is in good standing, in
                 each state where the failure to be so qualified could have a
                 material adverse effect on the operating condition (financial

                         (ii)  There is no litigation, arbitration, claim,

                 investigation before any court or before any public body or

                 with respect to Deli-Bon or its operations, businesses,
                 properties, assets, or financial condition except as properly
                 described in the Prospectus or such as individually or in the
                 aggregate do not now have and are not in the future reasonably
                 foreseeable to have a material adverse effect upon the
                 operations, business, properties, assets, or financial
                 condition of Deli-Bon.  Deli-Bon is not in violation of, or in

                 operations, business, properties, assets, or financial
                 condition of the Company; nor is Deli-Bon required to take any
                 action in order to avoid any such violation or default.

                 Deli-Bon or by which any of its properties or businesses may
                 be bound or affected and no event has occurred which with
                 notice or lapse of time or both would constitute such a

                                   EXHIBIT D

           [Legal opinion of ________________ [SIMPLY FRESH COUNSEL]]

                         (i)  Simply Fresh is a corporation duly organized,
                 validly existing, and in good standing under the laws of the
                 State of its incorporation, with full corporate power and
                 authority to own, lease, license and use its properties and
                 assets and to conduct its business in the manner described in
                 the Prospectus.  To the knowledge of such counsel, Simply
                 Fresh has all necessary consents, authorizations, approvals,
                 orders, certificates and permits of and from, and declarations
                 and filings with, all federal, state, local and other
                 governmental authorities and all courts and other tribunals,
                 to own, lease, license and use its properties and assets and
                 to conduct its business in the manner described in the
                 Prospectus.  Simply Fresh is duly qualified to do business and
                 is in good standing, in each state where the failure to be so
                 qualified could have a material adverse effect on the
                 operating condition (financial and otherwise) or business of
                 Simply Fresh or the Company.

                         (ii)  There is no litigation, arbitration, claim,
                 governmental or other proceeding (formal or informal), or
                 investigation before any court or before any public body or
                 board pending or to the knowledge of such counsel, threatened
                 with respect to Simply Fresh or its operations, businesses,
                 properties, assets, or financial condition except as properly
                 described in the Prospectus or such as individually or in the
                 aggregate do not now have and are not in the future reasonably
                 foreseeable to have a material adverse effect upon the
                 operations, business, properties, assets, or financial
                 condition of Simply Fresh.  Simply Fresh is not in violation
                 of, or in default with respect to, any law, rule, regulation,
                 order, judgment, or decree, except as is properly described in
                 the Prospectus or such as in the aggregate do not now have and
                 will not in the future have a material adverse effect upon the
                 operations, business, properties, assets, or financial
                 condition of the Company; nor is Simply Fresh required to take
                 any action in order to avoid any such violation or default.

                         (iii)  To the knowledge of such counsel, Simply Fresh
                 is not now nor is it expected by the Company to be in
                 violation or breach of, or in default with respect to,
                 complying with any term, obligation or provision of any
                 contract, agreement, instrument, lease, license, indenture,
                 mortgage, deed of trust, note, arrangement or understanding
                 which is material to Simply Fresh or by which any of its
                 properties or businesses may be bound or affected and no event
                 has occurred which with notice or lapse of time or both would
                 constitute such a default.

                         (iv)  Simply Fresh is not in violation or breach of,
                 or in default with respect to, any term of its certificate of
                 incorporation (or other charter documents)

RE: Registration Statement on Form S-1

Gentlemen:

        We have acted as counsel to The UniMark Group, Inc., a Texas
corporation (the "Company"), in connection with the registration under the
Securities Act of 1933, as amended (the "Securities Act"), of 2,300,000
shares (the "Shares") of common stock $.01 par value (the "Common Stock") of
the Company to be offered to the public by the Company.

        A registration statement on Form S-1 (SEC File No. 333-    ) is being
filed with the Securities and Exchange Commission on May 10, 1996 (the
"Registration Statement"). In connection with rendering this opinion we have
examined executed copies of the Registration Statement. We have also examined
and relied upon the original, or copies certified to our satisfaction, of (i)
the Articles of Incorporation, as amended, and the Bylaws of the Company, (ii)
minutes and records of the corporate proceedings of the Company with respect to
the issuance of the Shares and related matters, and (iii) such other agreements
and instruments relating to the Company as we deemed necessary or appropriate
for the purposes of the opinion expressed herein. In rendering such opinion, we
have made such further investigation and inquiries relevant to the transactions
contemplated by the Registration Statement as we have deemed necessary to the
opinion expressed herein, and have relied, to the extent we deemed reasonable,
on certificates and certain other information provided to us by officers of the
Company and public officials as to matters of fact of which the maker of such
certificate or the person providing such other information had knowledge.
Furthermore, in rendering our opinion, we have assumed that the signatures on
all documents examined by us are genuine, that all documents and corporate
record books submitted to us as original are accurate and

complete, and that all documents submitted to us copies are true, correct and
complete copies of the originals thereof.

        In issuing the opinion hereinafter expressed, we do not purport to be
experts in the laws of any jurisdiction other than the State of Texas and the
United States of America.

        Based upon the foregoing we are of the opinion that the Shares to be
issued by the Company in the Offering as described in the Registration Statement
have been duly and validly authorized for issuance and sale and the Shares, when
issued by the Company, will be validly issued, fully paid and nonassessable.

        We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. Consent is also given to the references to this firm
under the Caption "Legal Matters" in the prospectus included in the
Registration Statement as having passed upon certain legal matters in
connection with the Shares. In giving this consent, we do not thereby admit
that we come within the category of persons whose consent is required under
Section 7 of the Securities Act of rules and regulations of the Securities and
Exchange Commission promulgated thereunder.



                                        Sincerely,

                                        JORDAAN, HOWARD & PENNINGTON, PLLC
