                                     PART I

ITEM 1.  BUSINESS

THE COMPANY

         GENERAL

         KMG Chemicals, Inc., a Texas corporation (the "Company"), was
incorporated in the State of Texas in 1992 under the name Water Point
Manufacturing, Inc. In connection with the acquisition in 1996 of KMG-Bernuth,
Inc., a Delaware corporation ("KMG"), the Company changed its name to KMG-B,
Inc. In 1997 the Company changed its name to KMG Chemicals, Inc. The Company's
principal executive office is located at 10611 Harwin Drive, Suite 402, Houston,
Texas 77036 and its telephone number is (713) 988-9252.

         ACQUISITION OF KMG-BERNUTH, INC.

         In October 1996, the Company acquired all of the issued and outstanding
stock of KMG in exchange for 6,510,000 shares of the common stock, par value
$.01 per share ("Common Stock"), of the Company. After giving effect to a 1 for
1.5 reverse split of Common Stock outstanding immediately prior to the
acquisition of KMG, the former stockholders of KMG became owners of
approximately 93% of the issued and outstanding shares of Common Stock.

         Unless the context otherwise requires, references hereinafter to the
"Company" shall mean KMG Chemicals, Inc. and any of its subsidiaries. All
references hereinafter to share amounts reflect the reverse split of Common
Stock.

BUSINESS OF THE COMPANY

         GENERAL

         The Company manufactures and sells specialty chemicals in niche
markets. At the present time, the Company sells three wood preserving chemicals,
pentachlorophenol ("penta"), creosote and sodium pentachlorophenate ("sodium
penta"), and an herbicide product consisting of monosodium and disodium
methanearsonic acids ("MSMA"). The wood treating chemicals are sold to
industrial customers who use these preservatives to extend the useful life of
wood products, principally in the railroad, utility and construction industries.
MSMA is sold by the Company in the United States as Bueno(R) 6 to protect cotton
crops from weed growth and as Ansar(R) 6.6 for highway weed control. It also has
application elsewhere in the world to protect cotton and sugar cane.


                                       1
<Page>

         The Company acquired a penta manufacturing and distribution business in
1988 from an affiliated company that had been in the penta business since the
early 1970's. The Company made several acquisitions after 1988 to expand in wood
preserving products. It acquired a creosote distribution business in early 1991
and a sodium penta distribution business late that same year. In 1998, the
Company acquired significant additional assets pertaining to creosote. In
October 2000, the Company acquired its herbicide products line.

         The Company's strategy is to continue to grow through acquisitions. The
Company intends to seek, on a selective basis, acquisitions that complement and
expand its existing product lines. The Company's execution of this strategy
depends on its ability to identify, consummate and assimilate acquisitions on
desirable economic terms, to successfully integrate new product lines and expand
its existing product lines. There can be no assurance that the Company will be
successful in executing its growth strategy. Furthermore, the Company's ability
to implement its growth strategy may be dependent to a certain extent upon
obtaining financing for expansion, and there can be no assurance that financing
will be available on acceptable terms.

         PRODUCTS AND SERVICES

         WOOD PRESERVING CHEMICALS. The three primary chemicals used by the wood
preserving industry in the United States are penta, creosote and chromated
copper arsenate ("CCA"). The Company believes that wood preserving chemicals are
used to treat approximately 600 million cubic feet of wood each year in the
United States and that 6% of that wood is treated with penta, 15% with creosote
and 80% with CCA. The Company supplies the United States wood treating industry
with penta and creosote but not with CCA. The Company also supplies sodium
penta, a wood preserving product used primarily to treat freshly cut lumber, to
customers outside the United States. See "--Competition." The Company's wood
preserving chemicals constituted 89% of the Company's revenue in fiscal 2001 and
all of its revenue in fiscal 2000 and 1999.

         Penta is used primarily to treat electric and telephone utility poles,
protecting them from mold, mildew, fungus and insects. The Company manufactures
penta in Matamoros, Mexico through a subsidiary. The Matamoros facility produces
both solid penta blocks and penta flakes. Those penta products are sold by the
Company to its customers or made into a liquid solution of penta concentrate at
the Matamoros facility or at the Company's blending and distribution facility in
Tuscaloosa, Alabama. The penta blocks, flakes and solutions are sold to the
Company's customers in the United States, primarily in Washington, Oregon,
Oklahoma, Missouri, Arkansas, Mississippi, Alabama and Georgia. In addition, a
portion of the flaked penta is used to produce sodium penta. The Company sells
the sodium penta, which is not registered for use in the United States, to
customers primarily in Spain, Portugal, Peru, Ecuador and
Venezuela. As a by-product of the penta manufacturing process,


                                       2
<Page>

the Matamoros facility also produces hydrochloric acid which is sold to
distributors for use in the steel and oil well service industries in the United
States and Mexico.

         Creosote is a wood preservative used to treat railroad cross-ties,
bridge timbers and utility poles. Creosote is produced by the distillation of
coal tar, a by-product of the transformation of coal into coke. The Company has
two primary sources of supply for the creosote it sells in the United
States--Reilly Industries, Inc. ("Reilly") and Rutgers VFT AG ("Rutgers"). The
Company believes that Reilly and Rutgers are among the world's largest
manufacturers of creosote and other coal tar products. Creosote is sold by the
Company to customers throughout the United States.

         AGRICULTURAL CHEMICALS. The Company's MSMA agricultural chemicals
product line was acquired from Zeneca Ag Products, Inc. ("Zeneca") in October
2000. Zeneca's MSMA production facility was relocated to the Company's
Matamoros, Mexico facility and reassembled. It will be restarted late in
calendar 2001. The Company's MSMA herbicides are sold under the name Bueno(R) 6
in the United States to protect cotton crops, primarily in the southern
cotton-growing states and in California, and under the name Ansar(R) 6.6 to
state agencies to control highway weed growth.

         SUPPLIERS

         The Company is dependent upon outside suppliers for all of its raw
material requirements for its penta, sodium penta and MSMA manufacturing
operations and, therefore, is subject to fluctuations in the price of those
materials. The principal raw materials used in those operations are phenol,
chlorine, solvent, caustic, methylene chloride and arsenic trioxide, each of
which the Company purchases from a limited number of suppliers. The Company does
not maintain supply contracts with any of those suppliers of those raw
materials. However, the Company believes that these raw materials are each
readily available from a variety of sources and the loss of any of the Company's
suppliers would not have a material adverse effect on its business, financial
condition or results of operations.

         The Company has two suppliers of the creosote it sells. Under the
Company's long-term supply contract with Reilly, the Company must purchase
annual quantities at varying prices per pound. The Company's creosote supply
contract with Rutgers is renewable annually ending December 31. The Company must
purchase an agreed minimum volume in each calendar year. The purchase price for
creosote is fixed for calendar year 2001 but is subject to adjustment on
renewal.


                                       3

         CUSTOMERS

         The Company sells its chemical products to approximately 110 customers.
One customer, Kerr McGee Chemical Corp., accounted for approximately 15% of the
Company's revenues in fiscal 2001, 12% in fiscal 2000 and 15% in fiscal 1999. No
other customer accounted for 10% or more in those fiscal years.

         MARKETING

         The Company markets its chemicals in the United States through five
employees and one independent sales agent. Outside the United States, the
Company sells its products directly and through sales agency contracts to local
lumber producers or to chemical companies for those producers in over 20
countries.

         COMPETITION

         There are only a few firms competing with the Company in the sale of
its wood preservatives or MSMA products. The Company competes by selling its
products at competitive prices and maintaining a strong commitment to product
quality and customer service.

         The Company is one of only two companies producing penta for sale in
the United States. The Company believes that it currently supplies almost half
of the penta sold in the United States. The other penta producer in the United
States is Vulcan Chemicals, Inc., a company that has larger sales volumes and
greater financial and other resources than the Company. The Company believes
that there is one significant competitor for creosote sales in the United States
and two other lesser suppliers.

         There are three other firms that sell MSMA products in the United
States, primarily for use on cotton. For several years, however, cotton farmers
in the United States have been planting genetically modified cotton seed that is
resistant to the herbicide Roundup(R) and other glyphosate herbicides. As
farmers converted to that seed and to glyphosate herbicides, MSMA products
became niche products used primarily by farmers who are sensitive to the higher
cost of the genetically modified seed program. The companies selling resistant
seed and glyphosate herbicides have much greater financial and other resources
than the Company.

         Penta, creosote and MSMA must be registered prior to sale under United
States law. See "--Environmental and Safety Matters--Licenses, Permits and
Product Registrations." As a condition to registration, any company wishing to
manufacture and sell these products must provide to the EPA substantial
scientific research and


                                       4
<Page>

testing data regarding the chemistry and toxicology of the products. That data
must be generated by the applicant or the applicant must compensate other data
providers for relying on their information. The Company believes that the cost
of satisfying the data submission requirement serves as an impediment to the
entry of new competitors in the United States market, particularly those with
lesser financial resources. While the Company has no reason to believe that the
registration requirement will be discontinued or materially modified, there can
be no assurances as to the effect of such a discontinuation or modification on
the Company's competitive position.

         EMPLOYEES

         As of the end of fiscal 2001, the Company had a total of 55 full-time
employees. Ten of the Company's employees worked at the Company's corporate
offices in Houston, Texas, 39 at the Matamoros facility, six at the Tuscaloosa
facility and one worked in Louisiana. None of the employees in the United States
are represented by a labor union but 24 of the Company's employees in Mexico are
represented under a labor contract. The Company believes that it has good
relations with its employees.

         ENVIRONMENTAL AND SAFETY MATTERS

         The Company's operations are subject to extensive federal, state and
local laws, regulations and ordinances in the United States and abroad relating
to the generation, storage, handling, emission, transportation and discharge of
certain materials, substances and waste into the environment, and various other
health and safety matters. Governmental authorities have the power to enforce
compliance with their regulations, and violators may be subject to fines,
injunctions or both. The Company believes that it is currently in substantial
compliance with all such applicable laws and regulations. The Company must
devote substantial financial resources to ensure such compliance. For a
discussion of the Company's expenditures regarding environmental matters, see
"Item 6. Management's Discussion and Analysis of Financial Condition and Results
of Operations, Liquidity and Capital Resources."

         The Company anticipates that the regulation of its business operations
under federal, state and local environmental regulations in the United States
and abroad will increase over time. The Company cannot at this time estimate the
impact of increased regulation on the Company's operations, future capital
expenditure requirements or the cost of compliance.

         UNITED STATES REGULATION. Under the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended ("CERCLA") and
comparable state laws, an owner or operator of property from which releases of
hazardous


                                       5
<Page>

substances have occurred may be liable for investigation and remediation of any
resulting contamination. In addition, the generator of hazardous substances may
be responsible for all or a portion of any required investigation or remediation
at offsite disposal locations. Under the Resource Conservation and Recovery Act,
as amended ("RCRA"), a facility that treats, stores or disposes of hazardous
wastes on-site may be liable for corrective action costs. In addition to CERCLA
and RCRA, state laws and regulations may impose the same or broader liability.

         The Company's operations also are governed by laws and regulations
relating to workplace safety and worker health, principally the Occupational
Safety and Health Act and the regulations thereunder.

         MEXICO REGULATION. The Company's Matamoros facility and its operations
in Mexico are subject to various environmental laws, regulations and ordinances
promulgated by governmental authorities in Mexico. The Secretariat of
Environment, Natural Resources and Fisheries (SECRETARIATE DE MEDIO AMBIENTE,
RECURSOS NATURALES Y PESCA: "SEMARNAP") is given overall responsibility for
environmental regulation in Mexico. SEMARNAP's responsibilities include
enforcement of Mexico's laws and regulations concerning air and water emissions
and hazardous waste treatment, storage and disposal. SEMARNAP is given broad
authority to enforce compliance with environmental laws and regulations and can
require that operations be suspended pending completion of required remedial
action.

         LICENSES, PERMITS AND PRODUCT REGISTRATIONS. Certain licenses, permits
and product registrations are required for the Company's products and operations
in the United States, Mexico and other countries in which the Company does
business. The licenses, permits and product registrations are subject to
revocation, modification and renewal by governmental authorities. In the United
States in particular, producers of pesticides such as penta, creosote and MSMA
are required to obtain a registration for their products under the Federal
Insecticide, Fungicide and Rodenticide Act ("FIFRA") from the EPA in order to
sell those products in the United States. Compliance with the registration
system under FIFRA has had and will in the future have a material effect on the
Company's business, financial condition and results of operations. The
registration system requires an ongoing submission to the EPA of substantial
scientific research and testing data regarding the chemistry and toxicology of
pesticide products by manufacturers. Under an agreement with the other industry
participants, the Company shares research and testing costs pertaining to its
chemical products based on its relative market share. The Company incurred
expenses of approximately $716 thousand, $756 thousand and $721 thousand in
connection with the FIFRA research and testing program in fiscal 2001, 2000 and
1999, respectively.

earnings will be retained to finance the continuing development of its business.
The Company does not anticipate paying substantial dividends on the Common Stock
in the foreseeable future.

         In fiscal 2000 the Company granted a warrant to purchase 25,000 shares
of Common Stock at $5.50 per share to the assignee of Gilman Financial
Corporation. The warrant expires March 6, 2009 and was issued as compensation
for that company's acquisition consulting services. In fiscal 1999 the Company
also granted a warrant to acquire 25,000 shares of Common Stock to JP Turner &
Company, L.L.C. for consulting services pertaining to acquisition and financing
transactions and to investor relations. The warrant is exercisable at a price of
$5.50 per share of Common Stock through March 17, 2003. The warrants to Gilman
Consulting and to JP Turner & Company, L.L.C. were issued by the Company in
private transactions without registration in reliance upon the exemption from
registration under section 4(2) of the Securities Act of 1933, as amended.

</Table>

         SALES REVENUE

         2001 VS 2000. Net sales revenue in fiscal 2001 was 6% greater than in
fiscal 2000. Although sales revenue from the Company's wood treating chemicals
was down significantly in fiscal 2001, that decline was offset by the Company's
sales of MSMA products, which began during the second quarter of fiscal 2001.
Management believes that wood treating chemical sales declined in fiscal 2001
because commercial demand for railroad crossties and utility poles was below
historical levels during the year. Crosstie replacement projects appear to have
been deferred by major railroads. Deregulation and mergers in the utility
industry led to inventory consolidations that reduced overall demand for
replacement utility poles. Additionally, some utilities shifted to purchases of
poles treated with a competing product, CCA. Because the Company's penta product
is dissolved in oil to create a treating solution, higher diesel oil prices
since fiscal 2000 have meant that treating solutions made using CCA enjoyed a
widened price differential over the Company's product compared to historical
levels.

         Gross profit for fiscal 2001 was down 9.2% from the prior fiscal year
and the Company's gross profit margin declined to 33.5% from 39.2%. The decrease
in gross profit and margin was attributable to the decline in higher margin
penta sales.


                                       10
<Page>

         2000 VS 1999. Net sales revenue for fiscal 2000 was 7.2% less than in
fiscal 1999, a decline caused by reduced sales volume for the Company's wood
treating products. Penta product volume fell because utility company
consolidations in North America reduced demand for utility poles, the principal
wood product treated with penta, and because diesel oil prices were at
historically high levels. An additional factor, however, was that the Company's
penta-based sapstain product was not renewed for use in its two largest markets,
Chile and Malaysia. Creosote sales were adversely affected by a deferral of
railroad crosstie replacement by major railroads.

         Gross profit for fiscal 2000 increased 3.1% over fiscal 1999 and gross
profit margin increased from 35.2% to 39.2%. Higher per unit wood treating
chemicals sales revenues coupled with lower per unit manufacturing costs of
penta products helped maintain gross profit in the face of declining net sales
revenue.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

         Selling, general and administrative expenses for fiscal 2001 were $681
thousand higher than fiscal 2000 and fiscal 2000 was $305 higher than fiscal
1999. Most of the increase in fiscal 2001 was for expenses related to the MSMA
products line purchased in October 2000. The Company also incurred severance
costs in the most recent fiscal year for a force reduction at the Company's
manufacturing facility in Mexico. Selling, general and administrative expenses
increased in fiscal 2000 as compared to fiscal 1999 from increased testing and
research costs for creosote and from expenses incurred in pursuing growth by
acquiring niche chemical products. Also, the Company absorbed additional storage
and distribution expenses related to creosote purchased from Rutgers. Prior to
November 1998 the Company acted as an agent on behalf of Rutgers, and those
creosote expenses were borne by Rutgers. In November 1998 the agency arrangement
was terminated and the Company began to purchase creosote from Rutgers for its
own account and now bears creosote related expenses formerly absorbed by
Rutgers.

LIQUIDITY AND CAPITAL RESOURCES

         Cash and cash equivalents decreased in fiscal 2001 to $3.1 million as
compared with approximately $7.8 million and $4.8 million at the end of fiscal
2000 and 1999. The decrease in fiscal 2001 was attributable to the Company's
MSMA product line acquisition.

         The Company's wholly-owned subsidiary, KMG, has a working capital line
of credit under a Revolving Loan Agreement (as amended from time to time, the
"Revolving Credit Facility") with SouthTrust Bank of Alabama, National
Association ("SouthTrust"). Under the Revolving Credit Facility, the Company may
borrow up to the lesser of $3.5 million or a borrowing base (as defined
therein). The Revolving Credit Facility contains various representations and
warranties and affirmative and negative covenants applicable to KMG, including a
limitation that equity investments or loans by KMG not exceed $250 thousand and
a requirement to obtain the lender's consent prior to replacing the President
and chairman of the board of directors of KMG, David L. Hatcher, or any merger,
reorganization or recapitalization of KMG. In addition, the Revolving Credit
Facility requires KMG to maintain (i) a tangible net worth (as defined therein)
of not less than $5.0 million, (ii) a fixed charge coverage ratio of at least
1.25 to 1.0, and (iii) a ratio of liabilities to tangible net worth of not more
than 2.0 to 1.0 beginning at the end of fiscal 2000. As of September 30, 2001
the Company's borrowing base under the Revolving Credit Facility was $3.5
million and no amount had been borrowed.

         In fiscal 2001 the Company purchased its MSMA product line for $2.3
million and invested approximately $2.4 million in capital improvements, most of
which was for the relocation of the MSMA facility. The MSMA product line also
was responsible for the increased levels of Company inventory and trade accounts
receivable in fiscal 2001.

         In fiscal 1998 the Company purchased certain creosote registrations
that were financed in part by a $6 million term loan to KMG by SouthTrust. The
term loan bears interest at a fixed rate of 7.32%. It is being amortized over
seven years in equal monthly installments that total approximately $1 million
per year. In fiscal 1999 the Company prepaid an additional $1 million of
principal on the term loan. As of September 30, 2001, the principal balance
outstanding under the term loan was $2.4 million.

         The Company's capital expenditures and operating expenses for
environmental matters, excluding FIFRA testing and data submission costs, were
approximately $387 thousand in fiscal 2001 and $281 thousand and $300 thousand
in fiscal 2000


                                      12
<Page>

and 1999. The Company estimates that its capital expenditures and operating
expenses for environmental matters other than FIFRA will be approximately $508
thousand in fiscal 2002. The Company expensed approximately $716 thousand for
testing costs under FIFRA in fiscal 2001 and approximately $756 thousand and
$721 thousand testing in fiscal 2000 and 1999. Management believes that total
FIFRA testing costs for will be approximately $625 thousand in fiscal 2002.
Since environmental laws have traditionally become increasingly stringent, costs
and expenses relating to environmental control and compliance may increase in
the future. While the Company does not believe that the cost of compliance with
existing or future environmental laws and regulations will have a material
adverse effect on its business, financial condition or results of operations,
there can be no assurance that costs of compliance will not exceed current
estimates.

         The Company conducts periodic ground water sampling at its facility in
Tuscaloosa, Alabama as required by the Alabama Department of the Environmental
Management ("ADEM"). A 1991 sampling revealed the presence of penta
contamination and more recent sampling continues to show some contamination,
although in lesser amounts. ADEM has not required any additional response at
this time beyond the continuation of periodic monitoring. The Company does not
believe that costs for environmental investigation and remediation will
materially impact liquidity or have a material adverse effect on the Company's
business, financial condition or results of operations, although there can be no
assurances to this effect.

DISCLOSURE REGARDING FORWARD LOOKING STATEMENTS

         Certain information included or incorporated by reference in this
report is forward-looking, including statements contained in "Management's
Discussion and Analysis of Operations." It includes statements regarding the
intent, belief and current expectations of the Company and its directors and
officers. Forward-looking information involves important risks and uncertainties
that could materially alter results in the future from those expressed in these
statements. These risks and uncertainties include, but are not limited to, the
ability of the Company to maintain existing relationships with long-standing
customers, the ability of the Company to successfully implement productivity
improvements, cost reduction initiatives, facilities expansion and the ability
of the Company to develop, market and sell new products include uncertainties
relating to economic conditions, acquisitions and divestitures, government and
regulatory policies, technological developments and changes in the competitive
environment in which the Company operates. Persons reading this report are
cautioned that such statements are only predictions and that actual events or
results may differ materially. In evaluating such statements, readers should
specifically

consider the various factors that could cause actual events or results to differ
materially from those indicated by the forward-looking statements.

ACCOUNTING STANDARDS

         Statement of Financial Accounting Standards ("SFAS") No. 133,
"Accounting for Derivative Instruments and Hedging Activities," became effective
for the Company beginning August 1, 2001. SFAS No. 133, as amended and
interpreted, establishes accounting and reporting standard for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. Under SFAS 133, certain contracts that
were not formerly considered derivatives may now meet the definition of a
derivative. Management does not believe the adoption of SFAS 133 has a
significant impact on the financial position, results of operation, or cash
flows of the Company because it currently has no contracts that qualify as
derivatives under the provisions of this new standard. The Financial Accounting
Standards Board and the Derivatives Implementation Group continue to discuss
several issues that, once decided, could have additional impact on the Company's
financial statements.

         In July 2001, the FASB issued Statement of Financial Accounting
Standards No. 141 ("SFAS 141"), "Business Combinations." SFAS 141 requires the
purchase method of accounting for business combinations initiated after June 30,
2001 and eliminates the pooling-of-interests method. The Company does not
believe that the adoption of SFAS 141 will have a significant impact on its
financial statements.

         In July 2001, the FASB issued Statement of Financial Accounting
Standards No. 142 ("SFAS 142"), "Goodwill and Other Intangible Assets," which is
effective January 1, 2002. SFAS 142 requires, among other things, the
discontinuance of goodwill amortization. In addition, the standard includes
provisions for the reclassification of certain existing intangibles as goodwill,
reassessment of the useful lives of existing recognized intangibles,
reclassification of certain intangibles out of previously reported goodwill and
the identification of reporting units for purposes of assessing potential future
impairments of goodwill. SFAS 142 also requires the Company to complete a
transitional goodwill impairment test six months from the date of adoption. The
Company is currently assessing, but has not yet determined, the impact of SFAS
142 on its financial position and results of operations.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors of
   KMG Chemicals, Inc.:

We have audited the accompanying consolidated balance sheets of KMG Chemicals,
Inc. and subsidiaries (the "Company") as of July 31, 2001 and 2000, and the
related consolidated statements of income, stockholders' equity, and cash flows
for each of the three years in the period ended July 31, 2001. 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 auditing standards generally accepted
in the United States of America. 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, such financial statements present fairly, in all material
respects, the consolidated financial position of KMG Chemicals, Inc. and
subsidiaries as of July 31, 2001 and 2000, and the consolidated results of its
operations and its cash flows for the three years in the period ended July 31,
2001 in conformity with accounting principles generally accepted in the United
States of America.

KMG CHEMICALS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

 1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      GENERAL - KMG Chemicals, Inc. (the "Company") is principally involved in
      the sale and manufacture of specialty chemicals in niche markets. At the
      present time, the company sells three wood preserving chemicals,
      pentachlorophenol ("penta"), creosote and sodium pentacholorphenate
      ("sodium penta"), and an herbicide product consisting of monosodium and
      disodium methanearsonic acids ("MSMA"). Penta-manufacturing operations are
      conducted through KMG de Mexico ("KMEX"), a Mexican corporation and 99.98
      percent owned subsidiary, at a plant in Matamoros, Mexico. The penta plant
      began operations in 1986 and was moved to a new location in Matamoros in
      May 1997. The Company has two main suppliers of creosote, which it sells
      throughout the United States.

      The Company's MSMA agricultural chemicals product line was acquired form
      Zeneca Ag Products, Inc. ("Zeneca") in October 2000. The MSMA production
      facility acquired from Zeneca was relocated adjacent to the Company's
      penta manufacturing facility and reassembled. The Company's MSMA
      herbicides are sold under the name Bueno-Registered Trademark- 6 in the
      United States to protect cotton crops, primarily in the southern
      cotton-growing states and in California, and under the name
      Ansar-Registered Trademark- 6.6 to state agencies to control highway weed
      growth.

      The historical financial information of the Company reflects the
      historical results of KMG-Bernuth ("KMG") and KMEX as a result of a
      reverse merger of KMG with KMG-B, Inc. ("KMG-B") in October 1996. KMG-B
      was incorporated in the state of Texas in 1992 under the name Water Point
      Manufacturing, Inc. ("Water Point"). Water Point adopted "fresh-start"
      accounting as of October 23, 1996 and subsequently changed its name to
      KMG-B. On October 15, 1996, pursuant to a stock exchange agreement dated
      September 13, 1996, KMG-B issued 6,510,000 shares of common stock
      (approximately 93 percent of its issued and outstanding common stock) in
      exchange for all of the issued and outstanding shares of common stock of
      KMG. KMG-B also issued 352,474 shares of common stock to other
      shareholders as payment for certain services for KMG-B in connection with
      the stock exchange agreement and in conjunction with other services.
      During 1998, the Company changed its name to KMG Chemicals, Inc.

      The Company's significant accounting policies are as follows:

      PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
      include the accounts of KMG Chemicals, KMG-Bernuth, and KMEX. All
      significant intercompany accounts and transactions have been eliminated in
      consolidation.

      USE OF ESTIMATES - The preparation of financial statements in conformity
      with accounting principles generally accepted in the United States of
      America requires management to make estimates and assumptions that affect
      the reported amounts of assets and liabilities and disclosure of
      contingent assets and liabilities at the date of the financial statements
      and the reported amounts of revenues and expenses during the reporting
      period. Actual results could differ from these estimates.

      CASH AND CASH EQUIVALENTS - The Company considers all investments with
      original maturities of three months or less when purchased to be cash
      equivalents.

      INVENTORIES - Inventories are valued at the lower of cost or market. Cost
      is determined using the first-in first-out ("FIFO") method.

                                      21

<Page>

      PROPERTY, PLANT, AND EQUIPMENT - Property, plant, and equipment is stated
      at cost less accumulated depreciation and amortization. Major renewals and
      betterments are capitalized. Repairs and maintenance costs are expensed as
      incurred.

      INCOME TAXES - Deferred income tax assets and liabilities are determined
      using the asset and liability method in accordance with Statement of
      Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income
      Taxes." Under this method, deferred tax assets and liabilities are
      established for future tax consequences of temporary differences between
      the financial statement carrying amounts of assets and liabilities and
      their tax bases.

      EARNINGS PER SHARE - Basic earnings per common share amounts are
      calculated using the average number of common shares outstanding during
      each period. Diluted earnings per share assume the exercise of all stock
      options having exercise prices less than the average market price of the
      common stock using the treasury stock method.

      CURRENCY TRANSLATION - The U.S. dollar is the functional currency for the
      Company's foreign operations. For those operations, remeasurements to U.S.
      dollars from currency translations are included in the statement of
      income.

      STOCK-BASED COMPENSATION - The Company has adopted SFAS No. 123,
      "Accounting for Stock-Based Compensation." Under SFAS No. 123, the Company
      is permitted to either record expenses for stock options and other
      employee compensation plans based on their fair value at the date of grant
      or to continue to apply its current accounting policy under Accounting
      Principles Board Opinion No. 25 ("APB No. 25") and recognize compensation
      expense, if any, based on the intrinsic value of the equity instrument at
      the measurement date. The Company elected to continue following APB No. 25
      for stock options granted to employees; however, the Company accounts for
      stock options granted to non-employees under the provisions of SFAS 123.

      INTANGIBLE ASSETS - For financial statement purposes, intangible assets
      are being amortized using the straight-line method over the estimated
      useful lives of the assets (see Note 6).

      FAIR VALUE OF FINANCIAL INSTRUMENTS - The carrying value of financial
      instruments, including cash and cash equivalents, accounts receivable, and
      accounts payable approximate fair value because of the relatively short
      maturity of these instruments. The notes receivable, including the current
      portion, are of a related-party nature, and it is not practicable to
      estimate their fair value. The fair value of the Company's debt at July
      31, 2001 and 2000 was estimated to be the same as its carrying value since
      the debt obligations bear interest at a rate consistent with current
      market rates.

      CONCENTRATIONS OF CREDIT RISKS - Financial instruments that potentially
      subject the Company to significant concentrations of credit risk consist
      principally of cash and cash equivalents and accounts receivable. Although
      the amount of credit exposure to any one institution may exceed federally
      insured amounts, the Company limits its cash investments to high-quality
      financial institutions in order to minimize its credit risk. With respect
      to accounts receivable, such receivables are primarily from wood-treating
      manufacturers located worldwide. The Company extends credit based on an
      evaluation of the customer's financial condition, generally without
      requiring collateral. Exposure to losses on receivables is dependent on
      each customer's financial condition.

      NEW ACCOUNTING STANDARDS - Statement of Financial Accounting Standards
      ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging
      Activities," became effective for the Company beginning August 1, 2001.
      SFAS No. 133, as amended and interpreted, establishes accounting and
      reporting standard for derivative instruments, including certain
      derivative instruments embedded in other contracts, and for hedging
      activities. Under SFAS 133, certain contracts that were not formerly


                                      22
<Page>

      considered derivatives may now meet the definition of a derivative.
      Management does not believe the adoption of SFAS 133 has a significant
      impact on the financial position, results of operation, or cash flows of
      the Company because it currently has no contracts that qualify as
      derivatives under the provisions of this new standard. The Financial
      Accounting Standards Board and the Derivatives Implementation Group
      continue to discuss several issues that, once decided, could have
      additional impact on the Company's financial statements.

      In July 2001, the FASB issued Statement of Financial Accounting Standards
      No. 141 ("SFAS 141"), "Business Combinations." SFAS 141 requires the
      purchase method of accounting for business combinations initiated after
      June 30, 2001 and eliminates the pooling-of-interests method. The Company
      does not believe that the adoption of SFAS 141 will have a significant
      impact on its financial statements.

      In July 2001, the FASB issued Statement of Financial Accounting Standards
      No. 142 ("SFAS 142"), "Goodwill and Other Intangible Assets," which is
      effective January 1, 2002. SFAS 142 requires, among other things, the
      discontinuance of goodwill amortization. In addition, the standard
      includes provisions for the reclassification of certain existing
      intangibles as goodwill, reassessment of the useful lives of existing
      recognized intangibles, reclassification of certain intangibles out of
      previously reported goodwill and the identification of reporting units for
      purposes of assessing potential future impairments of goodwill. SFAS 142
      also requires the Company to complete a transitional goodwill impairment
      test six months from the date of adoption. The Company is currently
      assessing, but has not yet determined, the impact of SFAS 142 on its
      financial position and results of operations.

      RECLASSIFICATIONS - Certain reclassifications of prior year amounts have
      been made to conform to current year presentation.

      On October 3, 2000, the Company acquired the monosodium/-disodium
      methanearsonic acid ("MSMA") herbicides product line (see Note 6) and its
      manufacturing facility from Zeneca Limited, for a total acquisition cost
      of $2.3 million. The MSMA manufacturing facility, originally located in
      Houston, Texas, is being dismantled and reassembled adjacent to the
      Company's penta manufacturing facility in Matamoros, Mexico. Included in
      construction-in-progress at July 31, 2001 are costs of approximately $3.3
      million related to the purchase and relocation of the MSMA manufacturing
      facility.

      Depreciation is principally computed using a straight-line method over the
      estimated useful lives of the assets. Depreciation expense was $336,060,
      $333,712 and $310,344 in 2001, 2000 and 1999, respectively. The estimated
      useful lives of classes of assets are as follows:

 4.   FOREIGN CURRENCY REMEASUREMENT

      Monetary assets and liabilities and income items for KMEX are remeasured
      to U.S. dollars at current rates, and certain assets (notably plant and
      production equipment) are remeasured at historical rates. Expense items
      for KMEX are remeasured at average monthly rates of exchange except for
      depreciation and amortization expense. All gains and losses from currency
      remeasurement for KMEX are included in operations. Foreign currency
      remeasurement resulted in an aggregate exchange gain of $11,705 in 2001
      and $15,416 in 1999 and an aggregate exchange loss of $1,901 in 2000.

      On June 30, 1998, the Company entered into a long-term supply contract to
      purchase creosote (a wood-treating chemical) from Allied Signal, Inc.
      ("Allied"). At the same time, the Company purchased certain intangible
      assets from Allied pertaining to creosote sales and distribution. The
      Company paid Allied $4,000,000 and $4,500,000 for entering into the supply
      contract and for the intangible assets, respectively. The supply contract
      is being amortized on a straight-line basis over a 10-year term, which is
      the initial term of the contract. The intangible assets, including
      Allied's creosote customer list, one customer contract, certain rail car
      leases, and Allied's rights in creosote product registrations, are being
      amortized on a straight-line basis over a 15-year term which approximates
      the life of the assets purchased.

      During 1991, the Company entered into a technology-licensing agreement
      resulting in the granting to the Company of an exclusive worldwide right
      and license to use and sublease certain proprietary and sales information
      and to manufacture and sell certain products for an indefinite period of
      time. Total cost to the Company for this license was $320,000, which is
      being amortized on a straight-line basis over a 15-year term which
      approximates the patent life of the products represented by this
      agreement.

      On October 3, 2000, the Company acquired various intangible assets, such
      as brand names and customer lists, in connection with the purchase of the
      MSMA herbicides product line from Zeneca Limited (see Note 3).
      Approximately $1.15 million of the total $2.3 million acquisition cost was
      allocated to the intangible assets purchased. These costs are being
      amortized on a straight-line basis over a 15-year term, which approximates
      the life of the assets purchased.

 7.   LONG-TERM DEBT

      Effective August 1, 1996, the Company entered into a revolving
      line-of-credit agreement with a bank that provides for borrowings of up to
      $3,500,000. The borrowing base under this agreement is limited by a
      formula defined in the agreement based on the amount of receivables and
      inventory. Interest payments will be due monthly. The line of credit is
      subject to a one-fourth percent unused line fee and is secured by the
      Company's receivables, inventory, and general intangibles. The loan
      agreement includes, among other things, restrictions on equity investments
      and loans made by the Company and


                                      26
<Page>
      requires the maintenance of a minimum fixed-charge coverage ratio and
      minimum net worth requirements. No borrowings were outstanding under this
      agreement at July 31, 2001 or 2000. The termination date of this loan
      agreement is January 31, 2004.

      On June 26, 1998, the Company entered into a term loan with an original
      maturity date of July 1, 2005 for $6,000,000 with a bank. Starting August
      1, 1998, the Company began making monthly principal and interest payments
      of $91,498. This term loan is secured by the Company's receivables,
      inventory, and general intangibles. The interest rate of the term loan is
      fixed at 7.32 percent per annum. At July 31, 2001, the Company was in
      compliance with its various debt covenants which, among other things, has
      restrictions on equity investments and loans made by the Company and

      requires the maintenance of a minimum fixed-charge coverage ratio and
      minimum and ratio requirements on tangible net worth.

      The term loan note at July 31, 2001 matures as follows:

 8.   COMMITMENTS AND CONTINGENCIES

      OPERATING LEASES - The Company has noncancelable operating leases for its
      office and warehouse facilities and certain transportation equipment. At
      July 31, 2001, the Company was obligated under these leases for the
      following future minimum lease commitments:

                      2002                $  355,316
                      2003                   333,882
                      2004                   251,044
                                          ----------

                      Total               $  940,242
                                          ==========
</Table>

      Rent expense relating to the operating leases was $437,103, $346,138 and
      $317,361 in 2001, 2000 and 1999, respectively.

      ENVIRONMENTAL - As a manufacturer and supplier of wood treatment products
      and herbicides, the Company is subject to a variety of health, safety, and
      environmental laws within the countries in which it operates. These
      governments may implement new laws or regulations that amend or impose
      restrictions on the sale or use of the Company's raw materials and
      products. In management's opinion, the Company is currently in compliance
      with all applicable laws and regulations, and no actions or proceedings
      against the Company are known to be in process.

      Producers of chemicals such as penta, creosote and MSMA are required by
      the Environmental Protection Agency ("EPA") to obtain a registration for
      their products under the Federal Insecticide, Fungicide, and Rodenticide
      Act ("FIFRA") in order to sell those products in the United States. The
      registration system requires an ongoing submission to the EPA of
      substantial scientific research and testing data regarding the chemistry
      and toxicology of pesticides produced by manufacturers. Under an agreement
      with other industry participants, the Company shares the costs of the
      research and testing required by FIFRA, as well as possible compliance
      testing required by foreign governments, based on

                                      27
<Page>

      relative market share. In the current year, data obtained from these tests
      were consistent with historical test results and will not, in management's
      opinion, hinder the re-registration of the Company's pesticide products.

      The Company incurred expenses in connection with the FIFRA research and
      testing programs of approximately $716,000, $756,000 and $721,000 in 2001,
      2000 and 1999, respectively. These costs are included in selling, general,
      and administrative expenses.

      Future costs to the Company of the research and testing programs are
      difficult to quantify, since foreign governments have the authority to
      amend testing protocols and/or mandate additional tests. However,
      management estimates that these future costs will be approximately
      $625,000 per year and intends to expense these costs as incurred.

      LAWSUITS - The Company is involved in various claims and lawsuits in the
      normal course of business. Management does not believe that the outcome of
      any of these matters will have a materially adverse effect on the
      Company's consolidated financial position or results of operations.

 9.   RELATED-PARTY TRANSACTIONS

      During 1991, the Company entered into "split-dollar insurance"
      arrangements with two officers/stockholders. Under these arrangements, the
      Company advances funds for insurance premiums and records these advances
      as a noncurrent asset. The Company has a security interest in the
      insurance policies to the extent of the advances made. The security
      interest is to be satisfied either from death benefit proceeds or, in the
      event of termination of the arrangement(s), by reimbursement from the
      officer(s)/stockholder(s). During fiscal 1998, the arrangement with one
      such officer was terminated under the provisions of a five-year employment
      agreement and converted to a noninterest-bearing promissory note. As a
      portion of the officer's compensation under the employment agreement, the
      note is being amortized to compensation expense by the Company over a
      five-year period beginning January 1, 2000 (see Note 6); such amortization
      was $74,023 and $71,288 in 2001 and 2000, respectively.

      The Company advanced funds to an officer under unsecured promissory notes
      dated May 15, 1998 and July 15, 1994. The 1998 note was due in annual
      installments of $28,571, plus interest at 8 percent, with installments
      starting May 15, 2001. The 1994 note was due in semimonthly installments
      of $1,000, including interest at 6.5 percent. The amount outstanding under
      these notes was $0 and $428,057 at July 31, 2001 and 2000, respectively.

      In August 1998, the Company purchased a $200,000 participation in a loan
      by Sterling Bank to National Health Capital, Ltd. ("NHC"), a limited
      partnership engaged in purchasing medical receivables. In November 1998,
      the Company made an additional loan of $200,000 to NHC. At the time of
      these transactions, directors of the Company were directors of the general
      partner of NHC, limited partners in NHC, and one director was president of
      NHC. NHC ceased operations in 1999 and began the process of recovering on
      its assets and winding up its business. Management believes that at that
      time, and through the date that the interest in theses notes was purchased
      by an officer of the Company (see below), the notes receivable were
      collectible. Both loans were modified and renewed as of October 1999. The
      participation loan bore no interest and was due August 20, 2000. The
      second loan bore no interest and was due on September 30, 2000.

      On October 18, 2000, the Company completed its purchase of 180,000 shares
      of the Company's outstanding common stock from an officer at a price of
      $5.00 per share, the value of the Company's common stock on August 29,
      2000, the date on which the Company's Board of Directors approved the
      transaction. In accordance with the Company's desire to remove certain
      related party transactions from


                                      28
<Page>

      its accounts, the proceeds from the sale were used by the officer to
      purchase the Company's interest in the two NHC notes referred to above,
      and to repay the loans made to the officer by the Company in fiscal 1998
      and 1994.

10.   EMPLOYEE BENEFIT PLANS

      The Company has a defined contribution 401(k) plan covering substantially
      all of its U.S. employees. The participants may contribute from 3 percent
      to 15 percent of their compensation, and the Company makes matching
      contributions under this plan equal to 3 percent of the participant's
      compensation. Company contributions to the plan totaled approximately
      $30,000, $40,000 and $46,000 in 2001, 2000 and 1999, respectively.

      In July 2001, the Company adopted a supplemental executive retirement
      plan. Only persons specifically designated by the company may be
      participants in the plan. The plan is unfunded and amounts payable to
      participants are general obligations of the company. The plan provides
      that a participant will be paid a supplemental retirement benefit for 10
      years equal to a percentage of the participant's three-year average base
      salary at normal retirement. The benefit payable to participants is
      reduced by the equivalent actuarial value of the Company's other pension
      plan payments to the participant, if any, the Company's 401(k) plan and
      one-half social security benefits. Normal retirement is the earlier of age
      65 and completion of 10 years credited service or age 60 with 30 years
      credited service. As of July 31, 2001, none of the Company's executives
      were designated as a participant in the plan; however, one executive was
      designated as a participant in August 2001.

11.   SIGNIFICANT CUSTOMERS

      The Company had one significant customer in 2001, 2000 and 1999 whose
      sales as a percentage of total sales were 15 percent, 12 percent and 15
      percent, respectively.

12.   STOCKHOLDERS' EQUITY

      The Company adopted the 1996 Stock Option Plan (the "Stock Plan") on
      October 15, 1996 and reserved 700,000 shares of its common stock for
      issuance under the Stock Plan. The Stock Plan provides for the grant of
      "incentive stock options," as defined in Section 422 of the Internal
      Revenue Code of 1986, as amended, and nonqualified stock options. The
      Stock Plan will be administered either by the Company's Board of Directors
      or by a committee of two or more nonemployee directors. Subject to the
      terms of the Stock Plan, the Board of Directors or the committee has the
      authority to grant options under the Stock Plan, to amend, construe, and
      interpret it, and to make all other determinations and take any and all
      actions necessary or advisable for its administration. The directors,
      consultants, and key employees of the Company or any subsidiary are
      eligible to receive options under the Plan, which are fully vested upon
      issuance, but only salaried employees of the Company or its subsidiaries
      are eligible to receive incentive stock options, which vest over a
      five-year period from the date of issuance.

      Options will be exercisable during the period specified in each option
      agreement and in accordance with a vesting schedule to be designated by
      the Board of Directors or the committee. Any option agreement may provide
      that options become immediately exercisable in the event of a change or
      threatened change in control of the Company and in the event of certain
      mergers and reorganizations of the Company. Options may be subject to
      early termination within a designated period following the option holder's
      cessation of service with the Company.

      In 2000 the Company granted an option to acquire 40,000 shares of common
      stock in consideration for investor relations consulting services. These
      options would have vested if before January 1, 2000 the average closing
      price of the Company's common stock equaled or exceeded $9.00 per share
      for ten


                                      29
<Page>
      consecutive days, however, the options failed to vest and expired
      unexercised. Also in 2000 the Company granted warrants to acquire 25,000
      shares of common stock to JP Turner & Company L.L.P. for consulting
      services as requested by the Company and pertaining to the evaluation of
      acquisition and financing transactions and to investor relations. The
      warrants are immediately exercisable at a price of $5.50 per share of
      common stock through March 17, 2003.

      In 2000, the Company granted a warrant for the purchase of 25,000 shares
      of the Company's common stock to Gilman Financial Corporation, a company
      that employs a Director of the Company, in exchange for consulting
      services with respect to developing, studying, and evaluating merger and
      acquisition proposals. The warrant is immediately exercisable at a price
      of $5.50 per share of common stock through March 6, 2009.

      Stock option and warrants activity for the Company in 2001, 2000 and 1999

      At July 31, 2001, options were exercisable for 122,971 shares at a
      weighted-average exercise price of $3.41. The remaining contractual life
      of these options was approximately 7.9 years. At July 31, 2001, 355,829
      shares were available for future option grants.

      The weighted-average fair value of options granted during 2001, 2000 and
      1999 was $103,176, $114,314 and $95,488, respectively. The effect of these
      options would have decreased basic and diluted EPS by $.01 per share in
      2001 and $.02 per share during 2000 and 1999, respectively. Fair value of
      the options is estimated at the date of grant using the Black-Scholes
      option-pricing model with the following assumptions for fiscal years 2001,
      2000 and 1999:
