ITEM 1.   BUSINESS.

       GENERAL

              TETRA Technologies, Inc. ("TETRA" or "the Company") is a
specialty inorganic chemical company selling products, services and process
technologies to a variety of markets, including oil and gas, agriculture and
environmental services.  The Company's Specialty Chemicals Division
manufactures, recycles and markets certain specialty chemicals for various
industrial, agricultural and food industry uses.  Among other things, the
division converts low-cost chemical by-product streams produced by other
chemical plants into high-quality commercial products, which are marketed by
the Company.  The Division's Process Technologies Group provides engineered
systems and services that treat industrial and municipal wastewater and in some
cases, solid waste streams, to ensure compliance with environmental effluent
requirements, to achieve on-site waste minimization, and/or to recover reusable
constituents.  These systems employ the Company's proprietary biological
filtration, metals removal and resource recovery technologies, some of which
are patented.  The Division's Performance Chemicals Group develops
custom-tailored chemical treatment programs to meet specific customer needs,
and its Agriculture Group manufactures and distributes calcium chloride-based
agricultural products and zinc and manganese products for animal and plant
nutrition.

              The Company's Oil & Gas Services Division markets chemicals
including those produced by the Specialty Chemicals Division to the oil and gas
industry for use in well completion and workover operations in both domestic
and international markets.  They also provide complementary on-site fluid
engineering, fluid management and handling services and filtration for
completion and workover applications.  The Oil & Gas Services Division also
offers a specialty drilling fluids product line and oil and gas well plugging
and production testing services.

              TETRA Technologies, Inc. was incorporated in Delaware in 1981.
All references to the Company or TETRA include TETRA Technologies, Inc., its
subsidiaries, and their predecessors and subsidiaries.


       PRODUCTS AND SERVICES

              SPECIALTY CHEMICALS DIVISION.  The principal operations of the
Specialty Chemicals Division are the manufacture, recovery and marketing of
useful chemical products from by-product streams produced by industrial
chemical manufacturing processes.  The division's major facilities and
manufacturing operations are located in West Memphis, Arkansas; Lake Charles,
Louisiana; Wichita, Kansas; Parkersburg, West Virginia; Norco, Louisiana;
Magnolia, Arkansas; Fairbury, Nebraska; Tampico, Mexico and Orlando, Florida.

              The major products produced by this division include calcium
chloride, zinc bromide, calcium bromide, zinc chloride, zinc ammonium chloride,
zinc sulfate and manganese sulfate.  Liquid calcium chloride, zinc bromide and
calcium bromide are referred to as clear brine fluids ("CBFs") in the oil and
gas industry.  CBFs are solids-free, clear salt solutions that, like
conventional drilling "muds", have high specific gravities and are used as
weighting fluids to control bottom-hole pressures during oil and gas completion
and workover activities.  The use of CBFs increases production by reducing the
likelihood of damage to the well bore and productive pay zone.  CBFs are
particularly important in offshore completion and workover operations due to
the increased formation sensitivity, much greater investment necessary to drill
offshore, and the consequent higher cost of error.

              In 1995, the Company's Lake Charles facility embarked on a major
expansion program to significantly increase its production capacity of liquid
and dry calcium chloride.  The expanded liquid plant commenced production in
mid 1995 and the new dry production line began start-up operations in late
December with debottlenecking continuing through August 1996.  In 1996, the new
dry facilities successfully produced a new 80% calcium pellet, which
complements the 97% product currently produced and was enthusiastically
accepted in the marketplace.

              As part of the Specialty Chemicals Division, the Process
Technologies Group provides three principal types of systems and services:
biological filtration, heavy metals removal and chemical separation systems.
Biological filtration systems and services include deepbed filtration systems
that capture insoluble organics, oils, greases, nutrients, inorganics, digested
solids and viruses suspended in industrial and municipal effluents.  The
Company markets a proprietary process, Denite(R), which removes nitrogen and
suspended solids from wastewaters.  The Company also provides specialized
systems and services for the removal of heavy metals from wastewaters generated
by a variety of industrial and mining operations.  These systems incorporate
the Company's proprietary High Density Solids (HDS(TM)) process, which
concentrates metals solids into a dense product.  In some cases, this material
can be recycled by the customer or by the Company's Specialty Chemicals
Division.  Continuous Countercurrent Ion Exchange technology (CCIX(TM)) removes
and separates metals, acids, nutrients and other chemical constituents from
wastewater and potable water streams.  This proprietary process produces a
highly concentrated stream of the constituent removed and is used not only for
the efficient removal of unwanted wastewater constituents but for the
production of desired products from solutions of low concentration.

              The division's Performance Chemicals Group is a service-oriented
group that develops and monitors custom-tailored chemical treatment programs
to meet specific needs of its customers and then identifies, purchases and/or
blends a variety of polymers, resins and other chemicals, many of which the
Company has recycled, to meet these needs.  In conducting its business, the
Performance Chemicals Group defines and locates opportunities for the Company's
process technology applications.

              The division's Agriculture Group manufactures and distributes
calcium chloride-based agricultural products and zinc and  manganese products
for animal and plant nutrition.  The Company believes that calcium chloride is
one of the most efficient vehicles for delivering calcium to plants and, when
combined with nitrogen-based fertilizers, will dramatically increase the
efficiency of nitrogen fertilizers.  These products are sold as liquid blends
under the name N-CAL(R).   The Company's research has also discovered that
certain calcium chloride-based products will also eliminate sodium in the soil.
As a result, the Company has developed and introduced a soluble liquid calcium
blended product, ReNew(TM), that remediates severe sodium chloride contaminated
soils which occur naturally and as a result of spills of saltwater, as often
found at oil and gas well sites.  This product displaces the harmful sodium
with a concentrated source of calcium, helping to restore vegetation and
improve soil structure for increased water infiltration and permeability.  The
Company has also developed a related product, ACCEL(TM), that helps to
remediate soils contaminated with hydrocarbons.  This proprietary blend
contains nutrients that promote and accelerate growth of microorganisms present
in the soil for a more efficient and economical bioremediation process.

              The Agriculture Group expanded in late 1995 with the acquisition
of American MicroTrace Corporation ("AMT"). AMT manufactures and distributes
certain specialty chemicals, principally zinc sulfate and manganese sulfate
micronutrients.  These products are widely used to provide trace minerals to
meet the nutritional needs of animals and plants.  AMT acquires its zinc raw
material feedstocks from secondary sources and recycles them with sulfuric acid
to produce zinc sulfate.   In 1996, this group continued to expand its macro
and micronutrient product line for animal and plant nutrition with the
acquisition of Industrias Sulfamex S.A. de C.V. ("Sulfamex").  This company,
which  is located in Tampico, Mexico, manufactures manganese sulfate for
distribution predominately into U.S. markets.

              The Specialty Chemicals Division entered into the consumer
products market late in 1996 with the acquisition of Wilchem Corporation, which
sells products under the trade name Vapor Products.  Wilchem manufacturers
desiccants that reduce mold and mildew.  The primary ingredient in these
products is dry calcium chloride.  This acquisition has enabled the division to
vertically integrate its dry calcium chloride business and access the consumer
products markets.  The division plans to utilize Wilchem's distribution
channels to market certain other products.

              The division through its RETEC-TETRA joint venture with
Remediation Technologies utilizes various technologies, including a proprietary
thermal desorption technology to separate, collect and recycle volatile





                                     - 3 -
<PAGE>   5
hydrocarbons and other hazardous constituents from EPA-listed refinery sludges.
This thermal process has been approved by the EPA as "Best Demonstrated
Available Technology".  The joint venture entered the "Waste Derived Fuels"
market in 1993 with the acquisition of TRW's environmental services business,
which prepares oily refinery sludges for use as a fuel source to cement kiln
operators and for use in cokers.

              OIL & GAS SERVICES DIVISION.  The Oil & Gas Services Division
provides custom blended CBFs to most major oil and gas well operators, based on
the specific need of the customer and the proposed application of the product.
The division is currently supplying CBFs to oil and gas operators in both
international and domestic markets.  In addition, the division also provides
these customers a broad range of complementary services, including on-site
fluid filtration, handling and recycling,  fluid engineering consultation, and
fluid management assistance.  The Company also repurchases used calcium bromide
and zinc bromide CBFs from operators and recycles these materials.  Revenues
from repurchased CBFs reduce the net cost of the CBFs to the operators and the
cost and management investment involved in disposing of those fluids.  The
Company recycles the CBFs through filtration, blending and the addition of
chemicals, and then markets the recycled CBFs.

              The Oil & Gas Services Division's fluid engineering and
management employees use proprietary technology to determine proper blends for
a particular application to maximize the effectiveness and duration of the
CBFs.  The specific volume, density, crystallization point and chemical
composition of the CBFs are modified by the Company to satisfy a customer's
requirements.  The Company's filtration services involve the use of a variety
of techniques for the on-site removal of particulates from CBFs so that those
CBFs can be recirculated back into the well.  The Company's filtration systems
reduce fluid loss, which allows operators to complete and workover wells in
environmentally sensitive areas with greater safety.  This also enables
recovery of  a greater percentage of used CBFs for recycling.

              The economic viability of a well is determined through optimizing
oil and gas recovery from the producing zone (pay zone).  The Oil & Gas
Services Division, through its PayZone(R) Drilling Fluids product line, has
become a leader in the use of clear brine fluids for the protection of the
sensitive pay zone during drilling, completing, underreaming, reentry and
workover operations.

              The Oil & Gas Services Division's plugging and abandonment
business provides services onshore, in inland waters and offshore in Texas and
Louisiana for depleted oil and gas wells.  The division first entered this
business in 1994 with its acquisition of Pacer-Atlas in an effort to expand the
quality services offered to its customers and to capitalize on existing
personnel, equipment and facilities along the Louisiana and Texas Gulf Coast.
The plugging business was significantly expanded in 1996 with the purchase of
the assets of Culberson Well Service in Texas and Inland Rigs in Louisiana.
Altogether this business operates 26 onshore rigs, 5  barge-mounted rigs, one
jack-up rig and one offshore platform rig and has operating hubs in Bryan,
Rosenberg and Victoria, Texas and  Lafayette and Houma, Louisiana.  The
division further expanded the onshore services it offers by acquiring the
assets of Production Test, Inc. ("PTI") in 1996.  These operations provide
pressure and volume testing of oil and gas wells predominately in the South
Texas area.  PTI provides sophisticated evaluation techniques needed for
reservoir management and optimizing well work-over programs.

       SUPPLY OF RAW MATERIALS.

              SPECIALTY CHEMICAL DIVISION.  The primary sources of raw
materials for the Specialty Chemicals Division are certain chemical by-products
streams.

              At the Norco, Louisiana; Wichita, Kansas;  Lake Charles,
Louisiana; and Parkersburg, West Virginia calcium chloride production plants,
the principal source of raw material is by-product hydrochloric acid or weak
calcium chloride produced by other chemical companies.  The Company has written
agreements with those chemical companies regarding the supply of these raw
materials, but believes that there are numerous alternative supplies.
Substantial quantities of limestone are also consumed when converting acids to
calcium chloride.  The Company purchases limestone from several different
sources.  In addition, the Company is reviewing a proprietary process that may
permit the use of less expensive and more widely available limestone while
maintaining end-use product quality.





                                     - 4 -

              To produce zinc bromide, calcium bromide and zinc chloride at its
West Memphis facility, the Company consumes by-product hydrobromic acid and
various zinc byproducts and zinc oxide.  Hydrobromic acid is obtained from
several major producers of brominated  intermediate products.  The chemical
process to manufacture zinc bromide requires the purification of the zinc
by-products into a high quality zinc feedstock.  The zinc by-products are
obtained from a number of major steel companies and other sources.  In
addition, the Company is able to extract zinc from zinc-bearing sludges with
proprietary technologies supplied by its Process Technologies Group.

              The Company owns a calcium bromide manufacturing plant near
Magnolia, Arkansas, that was constructed in 1986 and has a capacity of 100
million pounds of calcium bromide per year.  It also owns certain lease rights
and lease option rights covering approximately 33,000 gross acres of bromine
reserves.  At December 31, 1996, TETRA had not yet commenced operations at the
plant.  While this plant is designed to produce calcium bromide, it could be
reconfigured and expanded to produce elemental bromine or select bromine
compounds.  The Company believes it has enough brine reserves to operate a
medium-size bromine facility for 25 to 30 years.  Development of the brine
field, which could take up to three years, and its associated pipeline and the
reconfigured plant would require a substantial additional capital investment by
the Company.

              In early 1997, the Company announced that it had entered into a
series of agreements with the Dow Chemical Company ("Dow") to purchase crude
bromine and build a bromine derivative plant at Dow's magnesium and calcium
chloride facility in Ludington, Michigan.  The new Ludington plant will give
the Company the flexibility to produce bromine, sodium bromide and calcium
bromide.  The Company's need for bromine or its derivatives has increased
steadily.  Starting as a principal component to the completion fluids business,
the demand has  increased with the use of sodium bromide in its PayZone(R)
Drilling Fluids and in its sales of biocides for the water treatment  business.

              OIL & GAS SERVICES DIVISION.  The Oil & Gas Services Division
purchases calcium chloride, calcium bromide and zinc bromide from the Specialty
Chemicals Division for resale to its oil and gas customers.  The Oil & Gas
Services Division recycles zinc and calcium bromide CBFs repurchased from its
oil and gas customers.  The Company also has purchased  CBFs from two domestic
and one foreign chemical manufacturer.  During 1996, the division entered into
a long-term supply agreement with a foreign producer of calcium bromide.  This
agreement, coupled with the products to be produced at the new Ludington plant
and its existing West Memphis, Arkansas plant, should afford the Company
additional flexibility in its development of the Magnolia plant, allowing it to
consider manufacturing other bromine derivatives at that facility.

       MARKET OVERVIEW AND COMPETITION

              Many of the major chemical companies devote limited resources to
the by-products produced by their own operations as a source of raw materials,
and instead rely on virgin feedstocks.  With the increasingly stringent
environmental regulations,  these companies have for a number of years sought
cost effective, environmentally safe methods of using and marketing of these
non-essential materials.  As a result, a market has evolved for the design,
manufacture, recycling and sale of non-essential materials and by-products.
The Company believes that the demand for its by-product conversion and
recycling services, including its marketing network for end-use products, could
increase in the future as environmental regulations become more stringent.

              The manufacture of calcium chloride from by-product acid is the
principal example of the Company's recycling operations.  The Company's major
competitors of dry calcium chloride include General Chemical Company, a
Canadian company, and Dow Chemical Company, the only other U.S. producer of
significant quantities of dry calcium chloride.  Management of the Company
believes that Dow is capable of producing approximately 800,000 tons of dry
calcium chloride annually through conventional manufacturing methods.  A
substantial investment would be necessary for a new competitor to manufacture
this product by conventional methods in sufficient quantities and at costs
necessary to compete.  With a smaller investment, the Company has been able to
produce and successfully market dry calcium chloride by using by-product acid,
thereby becoming a niche competitor in a market that is dominated by two larger
companies.





                                     - 5 -
<PAGE>   7
              Markets for the Company's liquid and dry calcium chloride include
sales to industrial, municipal, janitorial and consumer customers for snow and
ice removal, dust control, production of cement, road stabilization, oil and
gas operations, and certain agricultural and food industry activities.  In food
processing, calcium chloride is used to preserve crispness in certain canned
and bottled fruits and vegetables and to tenderize meat by enhancing enzyme
activity.

              The Company's agricultural operations produce liquid calcium
chloride and nitrogen products that are used in agricultural applications as
macronutrients to deliver calcium to crops, to reduce nitrogen volatilization,
to enhance nitrogen utilization and as a component of fertilizer that is
designed to improve crop yields and create healthier plants.  While sales have
improved significantly, they remain minuscule in comparison to the nitrogen
fertilizer market, which is predominately a dry product market.

              The Company's concept of using mineral acids, such as
hydrochloric, sulphuric  and hydrobromic acid to produce calcium chloride, zinc
bromide, zinc chloride, zinc sulfate and calcium bromides, has been expanded to
other chemicals and metals.  The Company is also recovering zinc from certain
byproducts for manufacturing into zinc chemicals, and is conducting pilot tests
on aluminum, nickel, copper and chrome recovery for resale as commercial
products.

              The Oil & Gas Services Division sells and markets clear brine
fluids and related products and services to all major markets worldwide.
Current foreign areas of market presence include the North Sea, Mexico, South
America, West Africa, Asia Pacific, and the CIS.  The Company has three
principal competitors in the sale of CBFs to the oil and gas industry:  Baroid
Corporation, M.I. and OSCA, Inc., a subsidiary of Great Lakes Chemical
Corporation.  This market is highly competitive and competition is based
primarily on service, availability and price.  Although Baroid and OSCA both
provide fluid handling, filtration and recycling services, the Company believes
that its historical focus on providing these and other value-added services to
its customers has enabled it to compete very successfully with both companies.
Because of the significant use of CBFs in deeper natural gas and offshore well
completions and workovers, a modest change in drilling in these areas could
have a material impact on the profitability of both the Specialty Chemicals and
Oil & Gas Services Divisions.

OTHER BUSINESS MATTERS

       CUSTOMERS

              The Specialty Chemicals Division sells its products and services
into retail distribution as well as end use markets.  Major customers of the
Oil & Gas Services Division include Shell Oil Company, Texaco, Baker Hughes,
Amerada Hess, British Petroleum, Oryx Energy, Unocal, Elf Acquitane, Chevron
USA, Phillips Petroleum Company, Conoco USA, and Atlantic Richfield
Corporation.

       MARKETING AND DISTRIBUTION

              The Specialty Chemicals Division markets its products through
offices in Pennsylvania, Virginia, Texas, Florida, Connecticut, California,
Georgia, Wyoming and Mexico, as well as through a network of distributors
located throughout the Midwest, Northeast, Southeast and Southwest.  To service
these distributors, the division has over two dozen distribution facilities
strategically located to provide efficient, low-cost product availability.  The
recent growth of the Company has allowed it to optimize its transportation
costs through the acquisition or the long-term leasing of customized
transportation equipment.

              The Oil & Gas Services Division markets its domestic products and
services through its sixteen distribution facilities located principally in the
United States' Gulf Coast region that are in close proximity to both product
supplies and customer concentrations.  Since transportation costs can represent
a large percentage of the total delivered cost of chemical products,
particularly liquid chemicals, the division believes that its strategic
locations make it one of the lowest cost suppliers of liquid calcium chloride
and other CBFs in the southern United States.





                                     - 6 -
<PAGE>   8
International markets that are served include the British and Norwegian sectors
of the North Sea, Colombia, Mexico, Venezuela, Western Africa and the Far East.

              In 1995, the Company made a significant investment to upgrade its
transportation, manufacturing and inventory control management information
systems.  New software was acquired and installed late in 1995 to provide
additional operating information to allow the Company to better manage
inventory levels and logistics, raw material supplies and plant operating
efficiencies.

              The marketing efforts of  the Process Technologies Group are
primarily conducted by senior technical and management professionals located in
Pittsburgh, Pennsylvania; Tampa, Florida; and The Woodlands, Texas.  These
people maintain communications with appropriate corporate representatives,
consulting firms and specialty contractors as sources of potential business.
This group retains specialized municipal sales representatives and monitors and
responds to requests for proposals for competitive bids.

       BACKLOG

              The Company ships most of its products within seven days of
receipt of an order.  Therefore, the level of backlog is not indicative of
corporate sales activity.  On December 31, 1996, the Company had an estimated
backlog of work of $2.9 million, all of which is expected to be billed during
1997.  On December 31, 1995, the Company had an estimated backlog of $4.3
million.

       EMPLOYEES

              As of December 31, 1996, the Company had 989 employees. The
Company believes that its relations with its employees are good.  None of the
Company's employees are covered by a collective bargaining agreement.

       PATENTS AND PROPRIETARY TECHNOLOGY

              The Company actively pursues a policy of seeking patent
protection both in the U.S. and abroad for appropriate technology.  The Company
owns or licenses 28 U.S. patents or patent applications and many foreign
counterparts. These patents expire at various times through 2014.  While the
Company believes that the protection of patents is important to its business,
the Company does not believe any one patent is essential to the success of the
Company.

              TETRA has historically utilized patents and trade secrets to
improve its manufacturing processes or to increase the value of its product
line.  Current growth is being fueled by a number of these items, including:
liquid N-CAL(R) fertilizer, new PayZone(R) products for oil and gas wells, and
a number of process technologies.  Since an incubation process is generally
required to take an idea or patent to commerciality, all of these items have
been in development for years.

              Some of the more recent additions to TETRA's portfolio of patents
and trade secrets could begin to contribute to profitability.  In response to
the need to develop a dry agricultural product to compliment liquid N-CAL(R),
TETRA has developed a line of granulated agricultural products that are
expected to be commercially marketed in 1997.  This is expected to allow the
Company to more rapidly penetrate the fertilizer and nutrient market.  TETRA's
Improved Metal Recovery (IMR) technology allows for the more efficient removal
of impurities, particularly from concentrated brines.  This is expected to
allow TETRA to utilize lower cost and lower grade limestone in the production
of calcium chloride.

              In early 1995, TETRA acquired the license to utilize certain
patents for the use of calcium chloride for use in the pulp and papermaking
industry.  The Company's Performance Chemical Group has developed
TETRA-Flux(TM), a zinc ammonium chloride additive used in metal finishing.
TETRA plans to expend significant capital and resources in the development of
proprietary technologies.





                                     - 7 -
<PAGE>   9
              The Company also relies on trade secrets, know-how and continuing
technological advancements to maintain its competitive position.  It is the
practice of the Company to enter into confidentiality agreements with key
employees, consultants and third parties to whom the Company discloses its
confidential and proprietary information.  There can be no assurance, however,
that these measures will prevent the unauthorized disclosure or use of the
Company's trade secrets and expertise or that others may not independently
develop similar trade secrets or expertise. Management of the Company believes,
however, that it would require a substantial period of time, and substantial
resources, to develop similar know-how or technology independently.  As a
policy, TETRA uses any legal means possible to protect its patents, trade
secrets and other proprietary information.

       ENVIRONMENTAL REGULATION

              Various environmental protection laws have been enacted and
amended during the past three decades in response to public concern over the
environment.  The operations of the Company and its customers are subject to
these evolving environmental laws and corresponding the regulations, which are
enforced by the EPA and various other federal, state and local environmental,
safety and health agencies and authorities. Efforts to comply with the
requirements of these laws have contributed to the demand for the Company's
services, but have also increased the Company's risk of liability for
environmental problems.  Although the Company's customers remain responsible by
law for compliance with environmental regulations, the Company must also comply
with the requirements of those environmental laws applicable to its operations,
which includes the Federal Water Pollutions Control Act of 1972 ("The Clean
Water Act"), the Resource Conservation and Recovery Act of 1976 ("RCRA"), the
Clean Air Act of 1977 ("The Clean Air Act"), the Comprehensive Environmental
Response, Compensation and Liability Act of 1980 ("Superfund") and the
Superfund Amendments and Reauthorization of 1986 ("SARA").

              There are a number of federal environmental regulatory programs
and most states and local authorities have enacted state and local laws
regulating activities affecting the environment, some of which impose stricter
standards than their federal counterparts.  Also, health and safety standards
have been promulgated by the federal Occupational Safety and Health
Administration ("OSHA"), including regulations related to the handling of
hazardous materials and wastes.  The Company and its customers and suppliers
are affected by these other regulatory programs.

              The Company's own operations are currently subject to certain
environmental regulations.  For example, at its Lake Charles, West Memphis,
Parkersburg and Fairbury plants, the Company holds permits regulating air
emissions and wastewater discharges from those plants or the disposal of
certain non-hazardous solid wastes.  The Company does not currently hold any
RCRA permits.  The Company is also subject to OSHA rules governing health and
safety, as well as certain federal and state community-right-to-know
regulations.

              The Company believes that its chemical manufacturing plants and
other facilities are in general compliance with all applicable safety, health
and environmental laws.  Since its inception, the Company has not had a history
of significant fines or claims in connection with safety, health or
environmental matters.  However, risks of substantial costs and liabilities are
inherent in certain plant operations and certain products produced at the
Company's plants, as they are with other companies engaged in the chemical
business, and there can be no assurance that significant costs and liabilities
will not be incurred.  Moreover, it is possible that other developments, such
as increasingly strict environmental, safety and health laws, and regulations
and enforcement policies thereunder, could result in substantial costs and
liabilities to the Company.  Changes in environmental regulations could subject
the Company's handling, manufacture, use, reuse, or disposal of materials at
the plants to scrutiny.  The Company cannot predict the extent to which its
operations may be affected by future enforcement policies as applied to
existing laws or by the enactment of new statutes and regulations.

  *  Comparison not meaningful


       1996 COMPARED TO 1995

              Revenues for the twelve months ended December 31, 1996 were
$160.8 million compared to $113.5 million in 1995, an increase of $47.3 million
or 41.7%.  Both the Oil & Gas Services Division and the Specialty Chemicals
Division showed significant revenue growth over the prior year.  In the Oil &
Gas Services Division, all three operating components (domestic, international
and plug and abandon) realized improved revenues.  Domestic operations
continued to benefit from the sustained levels of high drilling activity in the
Gulf of Mexico throughout the year, while international revenues improved
principally in Europe and Africa through a combination of increased drilling
activity and market penetration.  The Company believes it has minimal foreign
exchange exposure since the majority of its international operation activity is
denominated in U.S. dollars.  The plug and abandonment operations were
complemented during 1996 with several acquisitions that increased the land rig
fleet, added an inland waters fleet operating in Louisiana and Texas, and added
a production testing operation.  Revenues increased significantly as a result
of these operations.

              In the Specialty Chemicals Division, revenues from liquid and dry
calcium chloride sales increased in 1996 as the Company continued to
aggressively develop new domestic and international markets.  The division also
benefitted from increased sales of zinc sulfate and manganese sulfate derived
from acquisitions in late 1995 and early 1996.  Finally, revenues from the
acquisition of Wilchem Corporation, which manufactures mold and mildew
preventative products for retail distribution, in the fourth quarter of 1996
also contributed slightly to the Division's revenue growth.

              In the twelve months ended December 31, 1996, gross profits were
$48.6 million, up $10.9 million or 29.2% from $37.7 million in 1995.  Gross
profits as a percentage of revenues was 30.3% in 1996 versus 33.2% in 1995, a
decline of 2.9 points.  Gross profits increased significantly in both divisions
to keep pace with the revenue growth.





                                     - 13 -
<PAGE>   15
However, higher than expected production costs associated with the start-up of
the Specialty Chemicals Division's expanded calcium chloride facility at Lake
Charles, Louisiana resulted in the gross profit percentage decline.

              General and administrative expenses were $27.9 million in 1996
compared to $24.2 million in 1995, an increase of $3.7 million or 15.0%.  A
significant portion of the increase is attributable to the new operations
purchased during the year.  Additional costs associated with the expansion of
the Oil & Gas Services Division domestic and international operations also
contributed to these cost increases.  General and administrative expenses as a
percentage of revenues continued to decrease from 21.3% in 1995 to 17.3% in
1996.

              Operating income for the twelve months ended December 31, 1996
was $20.8 million compared to $13.4 million in 1995, an increase of $7.4
million or 54.7%.  This increase is the combined result of a gross margin
increase of $15.7 million due to increased revenue volume and a $4.6 million
decrease due to lower gross margin rates, offset by a $3.7 million increase in
general and administrative expenses.

              During the twelve months ended December 31, 1996, long-term debt
increased approximately $23 million as the Company utilized debt to execute its
internal and external growth strategy.  This increase in debt and corresponding
decrease in cash available for investment resulted in an increase in interest
expense and a decrease in interest income in 1996 compared to 1995.

              The effective tax rate for the income tax provision was 35.9% in
1996 compared to 35.7% in 1995.  The effective rates differ from the statutory
rates due principally to the effects of research and development tax credits
and permanent differences in 1996 and 1995.

              Net income after taxes for the twelve months ended December 31,
1996 was $13.1 million compared to $9.4 million in 1995, an increase of $3.7
million or 40.3%.  Net income per share was $0.97 in 1996 based on 13,545,000
weighted average common and common equivalent shares outstanding compared to
$0.72 in 1995 based on 13,069,000 weighted average common and common equivalent
shares outstanding.  Net income per share increased $0.25 or 34.7% in 1996.

       1995 COMPARED TO 1994

              Revenues for the twelve months ended December 31, 1995 were
$113.5 million, up $25.0 million or 28.2% over 1994 revenues of $88.5 million.
TETRA's Oil and Gas Division contributed significantly to this increase
benefitting from improvements in both domestic and international markets.
Domestic revenues improved substantially as drilling activity in the Gulf Coast
remained high.  Revenues from foreign operations increased principally due to
market penetration in Africa and Latin America.  Specialty Chemicals Division
revenues increased in 1995 as a result of higher sales of liquid calcium
chloride, zinc products and performance chemicals.  In addition, revenues from
the acquisition of American MicroTrace in October of 1995 and the acquisitions
of Pacer-Atlas and Baker Hughes INTEQ/TETRA in 1994 contributed to this
improvement.

              Gross profits for the twelve months ended December 31, 1995 were
$37.7 million compared to $29.1 million in the prior year, an increase of $8.6
million or 29.6%.  Gross margin as a percentage of revenues improved from 32.8%
in 1994 to 33.2% in 1995.  Improved pricing for liquid and dry calcium
chloride, combined with lower product costing achieved through enhanced
manufacturing processes and throughput, contributed to this margin improvement.
Additionally, improved margins from the waste treatment group of the Chemicals
Division also contributed to the enhanced profitability.

              General and administrative expenses were $24.2 million in 1995 or
21.3% of revenue compared to $21.1 million or 23.8% of revenue in 1994.  The
acquisition of American MicroTrace in 1995 and the acquisitions of Pacer-Atlas
and Baker Hughes INTEQ/TETRA in 1994 contributed to this increase.
Additionally, the Company incurred approximately $1.2 million in
non-recoverable legal costs in 1995 associated with the successful defense of a
civil legal action.  General and administrative expenses as a percent of
revenues continued to decrease to 21.3% in 1995 compared to 23.8% in 1994.

              Operating income for the twelve months ended December 31, 1995
was $13.4 million up $5.4 million or 67.5% from $8.0 million in 1994.  This
increase is attributable to a gross margin improvement of $8.2 million





                                     - 14 -
<PAGE>   16
relating to increased volume and $0.4 million from improved pricing offset by
increased general and administrative expenses of $3.2 million.

              Interest expense in 1995 was down as a result of the
capitalization of interest costs associated with the Lake Charles plant
expansion.

              The effective tax rate for the income tax provision was 35.7% in
1995 and 32.5% in 1994.  The effective rates differ from the statutory rates
due to the effects of research and development tax credits recorded in 1995 and
1994.

              Net income after taxes for the twelve months ended 1995 was $9.4
million compared to $6.1 million in 1994, an increase of $3.3 million or 54.1%.
Net income per share was $0.72 in 1995 based on 13,069,000 weighted average
common and common equivalent shares outstanding compared to earnings in 1994 of
$0.48 based on 12,693,000 weighted average common and common equivalent shares
outstanding.

       LIQUIDITY AND CAPITAL RESOURCES

              The Company's investment in working capital, excluding cash and
cash equivalents, increased $12 million in 1996 to $34.6 million.  Increased
trade accounts receivable balances and inventory levels accounted for this
increase.  The increase in accounts receivable amounting to $10.7 million
results from improved fourth quarter sales from international oil and gas
operations and from water treatment and metals concentration technologies.  The
1996 acquisitions of Industrias Sulfamex, S.A. de C.V. ("Sulfamex") and Wilchem
Corporation ("Wilchem") into the Specialty Chemicals Division also contributed
to this increase.  Inventories increased $8.1 million in 1996.  Inventories of
dry calcium chloride increased as production levels from the expanded Lake
Charles, Louisiana facility increased at year end.  Domestic Oil & Gas Division
inventories also increased in response to the increased drilling activity in
the Gulf of Mexico.  Finally, agricultural product inventories increased in
association with the acquisition of Sulfamex in 1996.  Acquisitions also
accounted for most the $4.3 million increase in accounts payable and accrued
expenses.  Current portion of long-term debt increased in 1996 by $2.7 million.
Most of this increase relates to reclassifying at December 31, 1996, $2.4
million of debt acquired along with the purchase of American MicroTrace in
1994.  In January 1997, the Company reduced its cost of capital by retiring the
long-term debt and working capital loans of its American MicroTrace subsidiary.
The $4.4 million payoff was funded from the Company's current revolving
line-of-credit.

              The Company has announced its intention to augment internal
growth with acquisitions.  The emphasis of these purchases has been and will
continue to be in areas where TETRA has technological leadership or existing
distribution channels such as acids, metals, agricultural products or oil and
gas services.  To fund this acquisition program, the Company will use existing
cash and cash flow as well as its general purpose, unsecured, prime rate/LIBOR
line-of-credit with NationsBank and Texas Commerce Bank.  As of December 31,
1996, the Company has $4 million in letters of credit and $23.4 million in
long-term debt outstanding against a $30 million line-of-credit.  Subsequent to
year end, the terms of the line were extended to $60 million maturing in 1999,
leaving a net availability of $32.6 million.   The Company is currently
negotiating to increase this line-of-credit to $120 million.  In addition to
this expanded line, the Company has 4.8 million shares of TETRA common stock
available under a shelf registration statement to finance its acquisition
program.

              Major investing activities during the twelve months ended
December 31, 1996 included the acquisition of several companies.  In the Oil &
Gas Services Division, three operations were acquired.  The assets of
Production Test, Inc. a well testing service company, and Culberson Well
Service, Inc., an oilfield service company, were purchased for $1.5 million and
$1.4 million, respectively.  The Company also acquired the outstanding stock of
three affiliated companies operating under the name of Inland Rigs.  The
acquired operations, which are predominantly involved in plugging wells in the
inland waters of Louisiana, were merged into the Division's plug and abandon
business.  The Company issued 164,101 shares of common stock valued at $24.38
per share for the acquired companies.  The Specialty Chemicals Division
completed two acquisitions in 1996.  The stock of Industrias Sulfamex was
purchased for $8.1 million.  Sulfamex is located in Tampico, Mexico and
manufactures manganese-based chemicals.  The Company also acquired the stock of
Wilchem, a major marketer of mold and mildew preventative products, for $7.5
million.  All of these cash acquisitions were funded by drawing against the
Company's line-of-credit.  Other investing activities include a $1.1 million
additional investment in the Company's 50% owned RETEC-TETRA

joint venture.  Finally, the Company has continued to lease significant
additional bromine reserves in close proximity to its Magnolia, Arkansas plant.

              Capital expenditures during the twelve months ended December 31,
1996 totaled approximately $12.1 million, a significant portion of which was
associated with the major expansion of the Lake Charles plant.  The expanded
dry calcium chloride facility began start-up operations in late 1995 with
de-bottlenecking continuing during the first and second quarters of 1996.  The
Company also acquired a 26,000 square foot building which will accommodate a
new technical center for both divisions.  The new facility, which will also
provide for pilot plant activities, will be occupied in the first quarter of
1997.  The Company's plant at Fairbury, Nebraska was also expanded to improve
the manufacturing process and provide enhanced mineral extraction from its raw
material sources.  These improvements will provide better utilization of raw
materials and reduce by-products.  Additional expenditures were incurred to
acquire oil and gas blending and filtration equipment, plug and abandon rig
equipment and speciality chemicals transportation and distribution equipment.

              The Company believes that its existing funds, cash generated by
operation, funds available under its bank line-of-credit, as well as other
traditional financing arrangements, such as secured credit facilities, leases
with institutional leasing companies, and vendor financing will be sufficient
to meet its current and anticipated operations and its anticipated capital
expenditures through 1997 and thereafter.

                         REPORT OF INDEPENDENT AUDITORS





Board of Directors and Stockholders
TETRA Technologies, Inc.

        We have audited the accompanying consolidated balance sheets of TETRA
Technologies, Inc. and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of operations, stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1996. Our
audits also included the financial statement schedule listed in the index at
Item 14(a). These financial statements and schedule are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits.

        We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the 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 TETRA Technologies, Inc. and subsidiaries at December 31, 1996 and 1995, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended December 31, 1996, in conformity with
generally accepted accounting principles. Also, in our opinion, the related
financial statement schedule, when considered in relation to the basic
financial statements taken as a whole, presents fairly in all material respects
the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               DECEMBER 31, 1996


NOTE A -- ORGANIZATION AND OPERATIONS OF THE COMPANY

    TETRA Technologies, Inc. was incorporated in Delaware in 1981.  All
references to the Company or TETRA include TETRA Technologies, Inc., its
subsidiaries, and their predecessors and subsidiaries.

    TETRA is a specialty inorganic chemical company selling products, services
and process technologies to a variety of markets, including oil and gas,
agriculture and environmental services. The Company's Specialty Chemicals
Division manufactures, recycles and markets certain specialty chemicals for
various industrial, agricultural and food industry uses. Among other things,
the division converts low-cost chemical by-products produced by other chemical
plants into high-quality commercial products, which are marketed by the
Company.

    The Company's Oil & Gas Services Division markets chemicals produced by the
Chemicals Division to the oil and gas industry for use in well completion and
workover operations in both domestic and international markets. They also
provide substantial fluid engineering, on-site fluid management and handling,
filtration, and other services.


NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

    The consolidated financial statements include the accounts of the Company
and its subsidiaries, all of which are wholly owned. The Company's investment
in joint venture is stated at cost plus equity in undistributed earnings. All
significant intercompany accounts and transactions have been eliminated in
consolidation.

Cash Equivalents

    The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents.

Inventories

    Inventories are stated at the lower of cost or market. Cost is determined
using the weighted average method. Inventories consist of finished products.

Financial Instruments

    The fair value of the Company's financial instruments which includes cash,
accounts receivable, short-term borrowings and long-term debt approximate their
carrying amounts. Financial instruments which subject the Company to
concentrations of credit risk consist principally of trade receivables. The
Company's policy is to evaluate, prior to shipment, each customer's financial
condition and determine the amount of open credit to be extended. The Company
will require the appropriate, additional collateral as security for credit
amounts in excess of approved limits. The trade receivables include activity
with oil and gas companies, municipalities and other industrial companies.

Long-Term Contracts

    The Company recognizes revenues and expenses from long-term construction
contracts using the percentage of completion method applying the cost to cost
method. These revenues and expenses are included in service revenues and cost
of revenues. Under this method, the Company recognizes as profit that
proportion of the total anticipated profit which the cost of work completed
bears to estimated total cost of the work covered by the contract. As contracts
extend over one year, revisions of cost and profit estimates are made
periodically and are reflected in the accounting period in which they are
determined. If the estimate of total costs indicates a loss, the total
anticipated loss is recognized immediately. Revenues and expenses from rental
and service contracts are recognized on a time and material basis.

Property, Plant and Equipment

    Property, plant, and equipment are stated at the cost of assets acquired.
Expenditures that increase the useful lives of assets are capitalized. The cost
of repairs and maintenance are charged to operations as incurred. For financial
reporting purposes, the Company provides for depreciation using the
straight-line method over the estimated useful lives of assets which are as
follows:

<TABLE>
    <S>                                             <C>
    Building  . . . . . . . . . . . . . . . . . .         25 years
    Machinery and equipment. . . . . . . . .  . .   5 and 10 years
    Automobiles and trucks  . . . . . . . . . . .          4 years
    Chemical plants . . . . . . . . . . . . . . .         15 years
</TABLE>  

    For income tax purposes, the Company provides for depreciation using
accelerated methods. Capitalized interest charged to construction projects for
the years ended December 31, 1996, 1995 and 1994 was $176,000, $450,000 and
$30,000, respectively.

Patents and Licenses

    Patents and licenses are stated on the basis of cost and are amortized over
the estimated useful lives generally ranging from 14 to 20 years.

Income Taxes

    The Company computes income tax expense using the liability method. Under
this method, deferred tax liabilities or assets are determined based on
differences between financial reporting and tax bases of assets and liabilities
and are measured using tax rates and laws that are in effect at year end.

Stock Compensation

        The Company has adopted Statement of Financial Accounting Standards
(SFAS) No. 123 "Accounting for Stock-Based Compensation". In accordance with
the provisions of SFAS No. 123, the Company applies APB Opinion 25 and related
interpretations in accounting for its stock option plans and continues to
account for stock-based compensation using the intrinsic value method.
Accordingly, compensation cost for stock options is measured as the excess, if
any, of the quoted market price of the Company's stock at the date of the grant
over the amount an employee must pay to acquire the stock. Note L to the
Consolidated Financial Statements contains a summary of the pro forma effects
to reported net income and earnings per share for 1995 and 1996 if the Company
had elected to recognize the compensation cost based on the fair value of the
options granted at grant date as prescribed by SFAS No. 123.

Income per Common and Common Equivalent Share

    Income per common and common equivalent share is computed using the
weighted average number of shares of common stock and common stock equivalents
outstanding during the year. Common stock equivalents consist of stock options
(calculated using the treasury stock and if converted methods, as applicable
during the periods such instruments were outstanding). A reconciliation of the
common shares used in the computations of income per common and common
equivalent shares is presented in Note M. Fully diluted earnings per share are
not presented because the result is not materially dilutive.

Foreign Currency Translation

    The accounts of the Company's foreign operations are translated into United
States dollars in accordance with SFAS No. 52. The U.S. dollar is the
designated functional currency for all of the Company's foreign operations,
except for those in the United Kingdom and Norway, where the British pound and
the Norwegian Kroner are the functional currency. The cumulative translation
effects of translating balance sheet accounts from the functional currency into
the U.S. dollar at current exchange rates are included as a separate component
of shareholders' equity.

Use of Estimates

    Management is required to make estimates and assumptions that affect the
amounts reported in the financial statements and accompanying notes.  Actual
results could differ from those estimates.

Reclassifications

    Certain previously reported financial information has been reclassified to
conform to the current year's presentation.

    Related Party Transactions

    The Company recorded sales and services rendered to unconsolidated joint
ventures of $1,201,000, $726,000, and $625,000 in 1996, 1995 and 1994,
respectively.

Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed Of

    In March 1995, the FASB issued Statement No.121, Accounting for the
Impairment of Long-Lived Assets and for Long- Lived Assets to Be Disposed Of,
which requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. Statement 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The adoption of Statement 121 in
the first quarter of 1996 had no effect on the financial statements.

Revenue Recognition

    Revenues are recognized when finished products are shipped to unaffiliated
customers or services have been rendered with appropriate provisions for
uncollectible accounts.

NOTE C -- ACQUISITIONS

    All acquisitions by the Company have been accounted for as purchases, with
operations of the companies and businesses acquired included in the
accompanying consolidated financial statements from their respective dates of
acquisition. The purchase price has been allocated to the acquired assets and
liabilities based on a preliminary determination of their respective fair
values. The excess of the purchase price over the fair value of the net assets
acquired is included in goodwill and amortized over 20 years. Pro forma
information for these acquisitions has not been presented as such amounts are
not material.

    In the fourth quarter 1996, the Company acquired the outstanding stock of
three affiliated companies operating under the name of Inland Rigs. The
acquired operations, which are predominantly involved in plugging wells in the
inland waters of Louisiana, were merged into TETRA's plug and abandon oil and
gas well service business. The Company issued 164,101 shares of common stock
valued at $24.38 per share for the acquired companies. The purchase agreement
also provides for additional purchase price consideration to be paid in the
common stock of the Company, contingent upon future incremental profits of the
Inland Rig's operations over the next two years. The fair market value of any
additional shares issued under this agreement will be capitalized as additional
purchase price. The excess of purchase price over the book value of net assets
acquired was approximately $4.4 million.

    The Company also consummated two additional acquisitions for cash during
the fourth quarter. The assets of Production Test, Inc., a well testing service
company, were purchased for $1.5 million. These assets were merged into TETRA's
domestic onshore service operations in the Oil & Gas Services Division. The
Company also acquired the stock of Wilchem Corporation for approximately $7.5
million. Wilchem Corporation is a major marketer of mold and mildew
preventative products and will be integrated into the Specialty Chemicals
Division's operations. The excess of the purchase price over the book value of
the net assets acquired of Wilchem Corporation was approximately $7.1 million.

    In the second quarter 1996, the Company acquired the outstanding stock of
Industrias Sulfamex, S.A. de C.V. ("Sulfamex") for approximately $8.1 million.
The excess of the purchase price over the book value of the net assets acquired
was approximately $2.2 million. Sulfamex is a Mexican corporation that produces
certain manganese-based chemicals for distribution, predominantly into U.S.
markets and was integrated into the Specialty Chemicals Division's operations.

    In the first quarter 1996, the Company purchased the assets of Culberson
Well Service, Inc. for approximately $1.4 million.  Culberson Well Service,
Inc. is an oilfield services company providing services along the Gulf Coast.
The assets purchased consisted of machinery and equipment.

        In the fourth quarter 1995, the Company purchased American MicroTrace
Corporation ("AMT") for 119,068 shares of common stock; the shares were valued
at $13.25 per share. The purchase agreement also provides for additional
purchase price considerations, to be paid in Company stock, contingent upon
future incremental profits of AMT through October 31, 1997. The fair market
value of any additional shares issued under this agreement will be capitalized
as additional purchase price. AMT is predominately a manufacturer and marketer
of specialty chemicals, most notably zinc sulfate and manganese sulfate. The
excess of purchase price over the book value of net assets acquired was
approximately $.9 million.

NOTE J -- COMMITMENTS AND CONTINGENCIES

         The Company, its subsidiaries and other related companies are named
defendants in several lawsuits and respondents in certain governmental
proceedings arising in the ordinary course of business. While the outcome of
lawsuits or other proceedings against the Company cannot be predicted with
certainty, management does not expect these matters to have a material adverse
impact on the financial statements.





                                      F-16

NOTE K -- CAPITAL STOCK

         The Company's Restated Certificate of Incorporation authorizes the
Company to issue 40,000,000 shares of common stock, par value $.01 per share,
and 5,000,000 shares of preferred stock, no par value. The voting, dividend and
liquidation rights of the holders of common stock are subject to the rights of
the holders of preferred stock. The holders of common stock are entitled to one
vote for each share held. There is no cumulative voting. Dividends may be
declared and paid on common stock as determined by the Board of Directors,
subject to any preferential dividend rights of any then outstanding preferred
stock.

         The Board of Directors of the Company is empowered, without approval
of the stockholders, to cause shares of preferred stock to be issued in one or
more series and to establish the number of shares to be included in each such
series and the rights, powers, preferences and limitations of each series.
Because the Board of Directors has the power to establish the preferences and
rights of each series, it may afford the holders of any series of preferred
stock preferences, powers and rights, voting or otherwise, senior to the rights
of holders of common stock. The issuance of the preferred stock could have the
effect of delaying or preventing a change in control of the Company. The Board
of Directors has no present plans to issue any of the preferred stock.

         Upon dissolution or liquidation of the Company, whether voluntary or
involuntary, holders of common stock will be entitled to receive all assets of
the Company available for distribution to its stockholders, subject to any
preferential rights of any then outstanding preferred stock.


NOTE L -- INCENTIVE STOCK OPTION PLAN

         In 1985, the Company adopted the TETRA Technologies, Inc. 1985
Incentive Stock Option Plan (the "1985 Plan"). In February 1990, the 1985 Plan
was amended to change the name of the 1985 Plan to the TETRA Technologies, Inc.
1990 Stock Option Plan (the "1990 Plan") and change the number and type of
options that could be granted.

         In 1993, the Company adopted the TETRA Technologies, Inc. Director
Stock Option Plan (the "Director's Plan"). The purpose of the Plan is to enable
the Company to attract and retain qualified individuals who are not employees
of the Company to serve as directors.

         The following is a summary of stock option activity for the years
ended December 31, 1994, 1995 and 1996:

</TABLE>


        The exercise price of the options outstanding at December 31, 1996
range from $5.88 to $21.63 per share. At December 31, 1996, 1995 and 1994,
there were 273,000, 381,000 and 366,000 shares, respectively, reserved for
future grants under the 1990 Plan. At December 31, 1996, 50,000 shares were
reserved for future grants under the Director's Plan. As of December 31, 1996,
there were 1,001,000 options outstanding which were exercisable under the 1990
Plan and 43,000 options exercisable under the Director's Plan.

        At December 31, 1996, the maximum number of shares authorized for
issuance under the 1990 Plan was 3,000,000 shares of common stock. Incentive
options may only be granted until December 31, 1999. As of February 28, 1997,
2,613,000 incentive stock options, 120,000 nonqualified options and no SARs had
been granted under the 1990 Plan. The maximum number of shares of common stock
which may be issued pursuant to options granted under the Director's Plan is
100,000. As of February 28, 1997, 55,000 options had been granted and were
outstanding under the Director's Plan.

           The Company has adopted Statement of Financial Accounting Standards
(SFAS) No. 123 "Accounting for Stock-Based Compensation". In accordance with
the provisions of SFAS No. 123, the Company applies APB Opinion 25 in
accounting for its stock option plans and, accordingly, does not recognize
compensation cost. If the Company had elected to recognize compensation cost
based on the fair value of the options granted at grant date as prescribed by
SFAS No. 123, net income and earnings per share would have been reduced to the
pro forma amounts indicated in the table below (in thousands except per share
amounts):

        The fair value of each option grant is estimated on the date of grant
using the Black-Scholes option-pricing model with the following assumptions;
expected stock price volatility 38.2%, expected life of options 4.3 years,
risk-free interest rate 6.00% and expected dividend yield 0.00%. The weighted
average fair value of options granted during 1996 and 1995 was $6.81 and $5.05
per share, respectively. The pro forma effect on net income for 1996 is not
representative of the pro forma effect on net income in future years because it
does not take into consideration pro forma compensation expense related to
grants made prior to 1995.

         Transfers between geographic areas are priced at the estimated fair
value of the products or services negotiated between the selling and receiving
units.

         In 1996 and 1995, two customers accounted for more than 10% of
consolidated revenues. Revenues from these customers were $20.7 million and
$15.9 million in 1996 and $20.5 million and $15.2 million in 1995. No single
customer accounted for more than 10% of consolidated revenues in 1994.

4.       FORECASTS AND ORDERS

         4.1     Firm Orders and Forecasts:

                 4.1.1    On or before *** of each year during the term of this
                          Agreement, TETRA shall notify BCL or its designated
                          Affiliate in writing of its a good faith estimate of
                          90% of the entire external requirements of TETRA for
                          Product for the next year (the "Base Amount").  TETRA
                          estimates that the Base Amount for *** will be ***.
                          Each year during the term hereof, TETRA agrees to
                          purchase, ***, at least *** of the Base Amount, as
                          equally as reasonably possible over the calendar
                          quarters covered by the Base Amount for such year.
                          TETRA agrees that it will not adjust the Base Amount
                          (upward or downward) from one contract year to the
                          next during the term hereof by more than *** from the
                          actual purchases by TETRA hereunder during the 12
                          month period immediately preceding such estimate;
                          provided, however, that, for purposes of making this
                          adjustment, TETRA may elect to exclude amounts
                          purchased hereunder that were in excess of *** of the
                          Base Amount, if any, from the amount of such actual
                          purchases.

                 4.1.2    BCL agrees to supply Product ordered by TETRA
                          hereunder, up to a maximum of *** of the Base Amount
                          for each year during the term hereof. If TETRA
                          requires more than *** of the Base Amount, BCL shall
                          not be obligated but shall have the right of first
                          refusal to supply *** of such excess, if a price can
                          be mutually agreed to by TETRA and BCL. *** .

         4.2     Purchase Orders:  TETRA shall fax or otherwise transmit
                 purchase orders or verbal instructions for firm quantities of
                 Product to BCL or its designated Affiliate.  Each such
                 purchase order shall specify the requested (A) quantity of
                 Product, (B) delivery time, (C) destination, and (D) labeling
                 instructions and may include other specific shipping, freight
                 or delivery instructions.  In the event of a conflict between
                 the terms of any purchase order of TETRA and this Agreement,
                 this Agreement shall control.

5.       DELIVERY AND ACCEPTANCE OF PRODUCTS

         5.1     Shipping: Products will be shipped *** or as agreed upon by
                 both parties to the destination specified by TETRA in its
                 purchase order and approved by BCL.

         5.2     Title and Risk of Loss:  Title to and risk of loss of Products
                 sold pursuant to this Agreement shall pass to TETRA ***

         5.3     Certificate of Analysis, Quality, Inspection and Acceptance:
                 BCL agrees to provide to TETRA, promptly after shipment, a
                 certificate of quality for each bulk shipment of Product sold
                 to TETRA hereunder with regard to the characteristics set
                 forth on the Specifications.  All quantities of the Product
                 delivered Pursuant to this Agreement shall be subject to
                 inspection, sampling and sampling retainage by Tetra at the
                 time the Product is delivered to determine their material
                 conformity with the Specifications.  If Product delivered does
                 not materially conform with the Specifications, TETRA shall
                 notify BCL of such non-conformity and shall promptly ship one
                 kilogram of the Product to BCL for evaluation.  BCL shall
                 promptly evaluate such Product and, if BCL determines that, as
                 a result of BCL's act or omission, the quality of Product does
                 not conform Specifications, then BCL shall, at Tetra's option,
                 either (i) credit Tetra's account by an agreed-upon amount, or
                 (ii) replace the non-conforming product and BCL shall notify
                 TETRA as to whether to return the non-conforming Product to
                 BCL.  BCL shall be responsible for all costs and related
                 expenses of return or disposal of non-conforming Product.  In
                 the event TETRA and BCL disagree as to whether the conforms to
                 the Specifications, the parties agree that a sample of the
                 allegedly non-conforming Product shall be provided to an
                 independent testing laboratory as to the conformity of the
                 Product to the Specifications shall be binding upon the
                 parties.  Credit of TETRA's account or replacement, at no
                 charge, of non-conforming quantities of the Product shall be
                 the sole and exclusive remedy of TETRA in the event of
                 non-conformance of the Product to the Specifications.

         6.1     No Default:  The failure of either BCL or TETRA to perform its
                 obligations under this Agreement, if caused by "Force Majeure"
                 (as hereinafter defined), shall not constitute a default
                 hereunder nor subject the party so failing to any liability to
                 the other; provided, however, that the party affected by such
                 Force Majeure shall promptly notify the other of (i) the
                 existence of such Force Majeure, (ii) its expected duration,
                 (iii) the estimated effect such Force Majeure will have on the
                 affected party's ability to perform its obligations hereunder,
                 and (iv) when such Force Majeure circumstance has ceased to
                 affect its ability to perform its obligations hereunder.

         6.2     Definition:  As used herein, the term "Force Majeure" shall
                 mean and include any circumstance beyond the reasonable

                 respect.  Either party shall also be in default under this
                 Agreement if it makes an assignment for the benefit of its

                 notice of its intention to terminate this Agreement detailing
                 the alleged default.  The defaulting party shall have thirty
                 (30) days from the date of receipt of such notice to cure the
                 default.  If the default is not cured within such (30) day
                 period, the non-defaulting party shall have the right to
                 terminate this Agreement immediately by giving written notice
                 thereof to the defaulting party.  The failure of the
                 non-defaulting party to so terminate this Agreement shall not
                 preclude it from giving notice under this Section to the
                 defaulting party with regard to the same or similar defaults
                 at any time in the future.

                 directly or indirectly, under a secrecy obligation to the
                 Disclosing Party, or (iii) which is, at the time of disclosure

                 connection with the validity interpretation and
                 performance of this Agreement that cannot be resolved
                 amicably by the parties shall be finally settled in
                 arbitration before a single arbitrator.  The parties
                 shall endeavor in good faith to mutually agree on the
                 selection of an arbitrator of commercial disputes
                 practicing in London, England.  If the parties cannot

                 apply to the London Chamber of Commercial Arbitration

                 by the substantive laws of England.  The arbitration
                 proceeding shall be held in London, England.

                 evidence in such proceedings shall be in the English
                 language.  The arbitrator will be required to give
                 detailed reasons for his determination.  The decision
                 of any such arbitrator shall be final and binding on
                 the parties.
     
                 Notwithstanding the aforesaid, the parties hereby acknowledge
                 that a breach by either party of this Agreement may not be
                 adequately compensated by monetary damages.  Accordingly, in
                 the event of such a breach, the parties recognize that the
                 non-breaching party may have the immediate right to secure an
                 order from any competent court enjoining such breach.  This
                 right shall be enforceable without prejudice to any other
                 rights the non-breaching party has in law or under this
                 Agreement.

         12.6    Waiver:  Any failure by either party to this Agreement to
                 comply with any of its obligations, agreements or covenants
                 hereunder may be expressly waived by the other party.  No
                 waiver by any part of any of its rights hereunder shall be
                 construed as a waiver of such rights in connection with any
                 subsequent failure.

         12.7    Entire Agreement:  This Agreement, together with the
                 Appendices described herein and delivered in connection
                 herewith, embodies the entire Agreement and understanding of
                 the parties hereto and supersedes any prior agreements or
                 understanding, written or oral, and all discussions between
                 the parties.  This Agreement can only be amended by a written
                 document duly executed by the parties and referencing that
                 this Agreement is being amended.

                 Agreement and its rights hereunder at any time during the term
                 hereof as security to any entity that provides financing to
                 TETRA (although any assignment by such entity upon foreclosure
                 must be approved by BCL in its reasonable discretion.

                 benefits of and be binding upon the parties hereto and their
                 respective successors and permitted assigns; provided,
                 however, that nothing in this Agreement shall be construed to
                 confer any rights, remedies, obligations or liabilities on any
                 person other than the parties hereto or their respective
                 successors and permitted assigns.
