                               PART I (CONTINUED)

ITEM 1. BUSINESS (Continued)

The backlog of orders at any one time is generally not significant to the
Company's business. At December 31, 1999, the Company's backlog of equipment
orders was approximately $800,000 and the Company expects to complete all of
these orders in the first half of 2000.

Raw materials essential to the Company's various products are generally
commodity materials and are readily available from competitive sources. The
Company's Solvents Division is continuing to go through a major transition in
the marketplace, primarily because of the phasing out of certain ozone depleting
solvents and other regulatory actions. As a result, the division is increasingly
marketing substitutes for such solvents, including aqueous based cleaners, is
expanding its permits to enable it to handle more waste codes, and is becoming
involved in the parts cleaning business.

The Company owns various patents and trademarks which aid in maintaining the
Company's competitive position; these expire at various times within the next
seventeen years. The expiration of such patents and trademarks should not have a
material adverse effect on the Company's operations. No material portion of the
Company's business is seasonal or subject to renegotiation of profits or
termination of contracts or subcontracts at the election of the government.

The approximate dollar amounts spent during 1999, 1998, and 1997 on research
sponsored by the Company were $1,286,000, $1,243,000 and $1,365,000,
respectively. The number of professional employees engaged in such activities
were 12 for 1999, 14 for 1998, and 16 for 1997.

There are no customers to which sales were made in an amount which equals ten
percent or more of consolidated revenues.

The Company does not expect to incur significant capital expenditures for
environmental compliance in 2000. However, the Company does expect to continue
to incur significant professional fees and expenses in connection with its
environmental compliance efforts. The Company maintains an environmental reserve
which at December 31, 1999 totaled $7.3 million, of which $1.5 million is
estimated to be spent in 2000. A more detailed discussion of environmental
matters is included under Item 3 - Legal Proceedings and in Management's
Discussion and Analysis in the Annual Report.

The Company employed 327 persons as of December 31, 1999.

The Company is not engaged in manufacturing operations in foreign countries. For
information regarding sales by customer location, see Note 15 to the
Consolidated Financial Statements.


                                                                               4

                               PART I (CONTINUED)

ITEM 1. BUSINESS (Concluded)

The Company utilized a combination of internally generated funds, the proceeds
from the sale of a closed plant and increased borrowings to finance its
activities during 1999. As of December 31, 1999, working capital was $3.7
million compared to $5.9 million at December 31, 1998. For a discussion of the
Company's Credit Agreement, see Note 5 to the Consolidated Financial Statements
and Management's Discussion and Analysis in the Annual Report.

The Company has market risks which could arise from fluctuations in interest
rates under both its Credit Agreement and the Industrial Development Bonds
issued by the California Economic Development Financial Authority. (see Notes 5
and 6 to the Consolidated Financial Statements). A 1% increase in the prime
interest rate could impact the Company's pretax earnings by approximately
$100,000 and a 1% increase in tax-exempt bond interest rates could affect pretax
earnings by a maximum of $35,000.

ITEM 2. PROPERTIES

The Company's administrative offices are located in approximately 7,500 square
feet of leased space at 24901 Northwestern Hwy., Suite 500, Southfield,
Michigan.

Detrex and its subsidiaries conduct manufacturing and research operations in
numerous locations of which ten are owned as follows:

1) Facilities located on 57 acres in Ashtabula, Ohio are used in connection with
the manufacture of hydrochloric acid, reagent grade chemicals, fine chemicals
including pharmaceutical intermediates, N-methyl pyrrole, and zinc-based
lubricant additives.

2) The Company's lubricants subsidiary, The Elco Corporation, manufactures gear
and oil additives in a plant located in Cleveland, Ohio on 5 acres of land and
59,000 square feet of office, research and plant space. This plant is equipped
with mixing and blending equipment and storage facilities.

3) The Company's plastic pipe subsidiary, Harvel Plastics, Inc. ("Harvel"),
manufactures plastic pipe in a plant located on 20 acres of land and 228,500
square feet of office and plant space located in Easton, Pennsylvania. Extruders
and special dies are used to manufacture the plastic PVC pipe from resin.
Production and warehouse facilities have been expanded several times since this
subsidiary was acquired in 1968.

     Harvel expanded its manufacturing capacity in 1998 by leasing a new 100,000
square feet facility in California, which was built to suit Harvel's warehouse
and manufacturing needs. The lease term is for an initial period of fifteen
years expiring in the year 2013, with provision for three five-year extensions.

4) Seibert-Oxidermo, Inc. manufactures primers and functional coatings for the
automotive industry in a plant located in Romulus, Michigan containing 45,000
square feet of office, research and plant space on 40 acres of land.
In addition, Seibert maintains a warehouse facility in Detroit, Michigan.

ITEM 3. LEGAL PROCEEDINGS

The Company and at least seventeen other companies are potentially responsible
for sharing the costs in a proceeding to clean up contaminated sediments in the
Fields Brook watershed in Ashtabula, Ohio. The Environmental Protection Agency
('EPA') issued a Record of Decision in 1986 concerning the methods it recommends
using to accomplish this task. The Company and the other potentially responsible
parties negotiated with the EPA as to how best to effect the clean up operation.
After negotiation, an agreement was reached with the EPA on clean-up
methodology. The Company's share of clean-up costs is anticipated to be in the
range of approximately $2.5 million.

The Company maintains a reserve for anticipated expenditures over the next
several years in connection with remedial investigations, feasibility studies,
remedial design, and remediation relating to the clean up of environmental
contamination at several sites, including properties owned by the Company. The
amounts of the reserve at December 31, 1999 and 1998 were $7.3 million and $8.0
million, respectively. The reserve includes a provision for the Company's
anticipated share of remediation in the Fields Brook watershed referred to
above, as well as a provision for costs that are expected to be incurred in
connection with remediation of other sites. Some of these studies have been
completed; others are ongoing. In some cases, the methods of remediation remain
to be agreed upon.


                                                                               6

ITEM 3. LEGAL PROCEEDINGS (Concluded)


The Company expects to continue to incur professional fees, expenses and capital
expenditures in connection with its environmental compliance efforts. In
addition to the above, there are several claims and lawsuits pending against the
Company and its subsidiaries. The Company expects to continue to incur
professional fees, expenses and capital expenditures in connection with its
environmental compliance efforts. In addition to the above, there are several
other claims and lawsuits pending against the Company and its subsidiaries. One
of those lawsuits involves the division of costs between several potentially
responsible companies for reimbursement to the EPA for costs it incurred to
conduct environmental remediation at a drum and barrel recycler, which the
Company had utilized several years ago. The potentially responsible companies
entered into an Agreement to, among other things, jointly defend the cost claims
of the EPA. A dispute arose amongst the potentially responsible companies over
the Agreement which resulted in the filing of a lawsuit. The matter went to
trial before a jury in June of 1999 and a judgment was entered against the
Company in the amount of approximately $750,000, plus interest and attorney
fees. The Company is taking an appeal to the Michigan Court of Appeals and
believes it has reasonable grounds to seek reversal of the judgment.

         The amount of liability to the Company with respect to costs of
remediation of contamination of the Fields Brook watershed and of other sites,
and the amount of liability with respect to several other claims and lawsuits
against the Company, was based on available data. The Company has established
its reserves in accordance with its interpretation of the principles outlined in
Statement of Financial Accounting Standards No. 5 and Securities and Exchange
Commission Staff Accounting Bulletin No. 92. In the event that any additional
accruals should be required in the future with respect to such matters, the
amounts of such additional accruals could have a material impact on the results
of operations to be reported for a specific accounting period but should not
have a material impact on the Company's consolidated financial position.

No matter was submitted to a vote of security holders during the fourth quarter

                               SIXTH AMENDMENT TO
                                CREDIT AGREEMENT



         THIS SIXTH AMENDMENT ("Amendment") dated as of February 29, 2000, by
and among the borrowers listed on Schedule 1 (collectively "Companies") and
Comerica Bank, a Michigan banking corporation ("Bank").

                                    RECITALS:

         A.   Companies and Bank entered into a Credit Agreement dated as of
June 13, 1996, which was amended by five amendments (as amended, "Agreement").

         B.   Companies and Bank desire to amend the Agreement and the Equipment
Notes (as defined in the Agreement) as hereinafter set forth.

         NOW, THEREFORE, the parties agree as follows:

         1.   The definitions of Revolving Credit Commitment, Revolving Credit
Maturity Date, Equipment Line Maturity Date, Lending Availability and Equipment
Reliance set forth in Section 1 of the Agreement are amended to read in their
entireties as follows:

              "Equipment Line Maturity Date' shall mean May 1, 2001.

              "Equipment Reliance' shall initially mean $750,000. On the
         first day of each month, beginning March 1, 2000, Equipment Reliance
         shall decrease by $50,000 until such time as the Equipment Reliance is
         zero.

              "Lending Availability' shall mean as of any date of
         determination thereof, the sum of (a) eighty five percent (85%) of
         Eligible Accounts plus (b) thirty five percent (35%) of Eligible
         Inventory; provided, however, in no event shall the amount of Lending
         Availability determined under this clause (b) exceed Four Million
         Dollars ($4,000,000), plus (c) the amount of the Equipment Reliance as
         of such date.

              'Revolving Credit Commitment' shall mean Thirteen Million
         Dollars ($13,000,000), subject to reduction or termination pursuant to
         Section 2.6 hereof.

              'Revolving Credit Maturity Date' shall mean May 1, 2001."

         2.   Section 2.A.2 is amended to read in its entirety as follows:



<PAGE>   2




              "2.A.2 The indebtedness represented by each Equipment Note shall
         be payable in equal monthly principal installments equal to the amount
         necessary to amortize the original amount of the Equipment Note over a
         five year term commencing on the first day of the first month after
         such loan is made and on the first day of each month thereafter until
         the maturity date thereof, when the entire unpaid balance of principal
         and interest thereon shall be due and payable. The maturity date for
         each Equipment Note shall be the date which is five (5) years after the
         date thereof. In addition to the above required payments on principal,
         Company agrees to pay interest on the unpaid principal balance of each
         Equipment Note from time to time outstanding at a per annum rate equal
         to one percent (1%) above the Prime Rate, provided, however, upon the
         occurrence of any Event of Default hereunder, interest shall be payable
         at a per annum rate of four percent (4%) above the Prime Rate. Interest
         payments shall be made monthly, commencing on the first day of the
         first month following the advance under the applicable Equipment Note
         and on the first day of each month thereafter. Interest shall be
         computed on a daily basis using a year of 360 days for the actual
         number of days elapsed, and in such computation effect shall be given
         to any change in the interest rate resulting from a change in the Prime
         Rate on the date of such change in the Prime Rate."

         3.   The first three sentences of Section 4.1 of the Agreement are
amended to read in their entirety as follows:

              "The Revolving Credit Notes and the Advances under Section 2
         hereof shall bear interest from the date thereof on the unpaid
         principal balance thereof from time to time outstanding, at a rate per
         annum equal to three quarters of one percent (3/4%) plus the Prime
         Rate. Interest shall be payable monthly on the first Business Day of
         each calendar month, commencing on the first Business Day of the
         calendar month during which such Advance is made, and at maturity.
         Notwithstanding the foregoing, from and after the occurrence of any
         Event of Default and during the continuation thereof, the Advances
         shall bear interest, payable on demand, at a rate per annum equal to
         three and three quarters percent (3-3/4%) above the Prime Rate."

         4.   Sections 9.1, 9.2, 9.3 and 9.4 are amended to read in their
entireties as follows:

              "9.1   Leverage Ratio. Beginning December 31, 1999, permit the
         Consolidated Leverage Ratio at any time to be more than 2.75 to 1.0."

               9.2   Cash Flow Coverage Ratio. Permit the Consolidated Cash
         Flow Coverage Ratio at any time to be less than the amounts specified
         below for the determination date specified below:

         December 31, 1999                                            .30 to 1.0
         March 31, 2000                                               .30 to 1.0

         September 30, 2000                                           .30 to 1.0
         December 31, 2000 and as of the last day of each fiscal
           quarter thereafter                                         .50 to 1.0

              9.3  Current Ratio. Beginning December 31, 1999, permit the ratio
         of Consolidated Current Assets to Consolidated Current Liabilities at
         any time to be less than 1.0 to 1.0.

              9.4  Consolidated Tangible Net Worth. Permit Consolidated Tangible
         Net Worth at any time to be less than the following amounts during the
         periods specified below:

         December 31, 1999 through December 30, 2000                $16,000,000

</TABLE>

         6.   Exhibit "E" to the Agreement is deleted and attached Exhibit "E"
is substituted therefor.

         7.   Each of the existing Equipment Notes is amended to increase the
non-default interest rate to the rate set forth in Section 2.A.2 of the

         8.   The Companies did not comply with the provisions of Sections 9.1,
9.2, 9.3 and 9.4 of the Agreement for the period ended December 31, 1999 (as
such provisions were in effect prior to this Amendment). The Bank hereby waives
any default under the Agreement arising as a result of such non-compliance with
the prior provisions for the period ended December 31, 1999. This is not a
waiver of any non-compliance for any period for such covenants as amended by
this Amendment.

TO OUR SHAREHOLDERS:

     While this past year was a very difficult one in many of our markets and
our financial results were not satisfactory, we made substantial progress in
positioning our businesses for improved revenue growth and higher profitability.

     Despite realizing stronger year over year revenue gains in each successive
quarter, we incurred a loss of $1.1 million in 1999. Disappointing operating
results in several of the operations were aggravated by significant costs
incurred to improve profitability, manage environmental liabilities and dispose
of non-utilized assets as well as by a large operating loss in the Automation
business which has been sold. Manufacturing facilities were consolidated at both
Elco and Seibert-Oxidermo during the year, at a cost in excess of $700,000. This
action will improve productivity beginning this year. Costs were also incurred
for launching manufacturing operations at Harvel's California plant; currently
the plant is operating efficiently and providing additional capacity for both
PVC and CPVC pipe. In addition to these actions, we sold an idle plant and
continue to resolve environmental matters.

     While much effort was focused on improving our cost position for the
future, we continue to make significant investments in product development.
During the year we commercialized such diverse products as Harvel LXT pipe for
ultra-pure water systems, aqueous parts cleaning chemistry and equipment,
Seibert's PopFree primer for improving the quality of SMC parts, and introduced
an environmentally friendly hydraulic additive by Elco.

     We are encouraged by the sales outlook for the first quarter as the
strengthening trend experienced quarter by quarter during 1999 has continued in
January and February. We anticipate revenue for the first quarter being higher
than in any quarter of 1998 and 1999. This development is the result of actions
taken in the business units to improve volume. Significant capital expenditures
have been made at both Harvel and Elco to facilitate volume growth in existing
products. At Seibert, technical resources have been devoted to strengthening our
position in coatings for plastic automotive components. The Solvents division
has been working to offset shrinking traditional markets with introduction of
alternative chemistries and parts cleaning services. The market for cleaning
equipment continues to be down and we are beginning to use manufacturers
representatives to improve coverage.

     We expect improved performance from the business units in the coming year
based on the combination of higher sales and cost reductions. Strategic and
operational actions are ongoing to drive continued improvement in the businesses
and the company as a whole. Our objective is to grow shareholder value. The
initial step is to operate all our businesses on a profitable basis and to
generate positive cash flow from operations. In 1999 we sold two divisions that
were non-core and we now have five business units:

     - Harvel Plastics

     - Elco Corporation

     - Seibert-Oxidermo

     - Solvents and Environmental Services division

     - Equipment division

Three of these had operating income in 1999. The challenge is to realize
improved profitability in these three units while addressing strategic issues in
the other two.

     We realize the impact of our operating results on the value of your
investment over the last two years and thank you for your patience. We are
committed to improving results and increasing the value of your investment.

To the Board of Directors and Stockholders of
  Detrex Corporation

We have audited the accompanying consolidated balance sheets of Detrex
Corporation and its subsidiaries (the Company) as of December 31, 1999 and 1998
and the related consolidated statements of operations and retained earnings and
of cash flows for each of the three years in the period ended December 31, 1999.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the 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 consolidated financial statements present fairly, in all
material respects, the financial position of Detrex Corporation and its
subsidiaries at December 31, 1999 and 1998 and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1999 in conformity with generally accepted accounting principles.

DETREX CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND CUSTOMER CONCENTRATION

     Detrex Corporation and its subsidiaries (the Company) operate predominantly
in chemicals and allied products, services, and processes for use by
manufacturing and service industries. The principal products and services
include specialty chemicals, lubricant additives, parts cleaning, cleaning
solvents, hydrochloric acid, PVC and CPVC plastic pipe, automotive and
industrial paints, and degreasing equipment.

     All of the Company's business units operate in highly competitive markets
which are mainly national in scope, although approximately 12% of the Company's
business in 1998 and 1999 was done outside the United States, principally by its
lubricants subsidiary and its plastic pipe subsidiary. Generally, for all
products there are numerous competitors with no one company or a small number of
companies being dominant. The Company operates in niche markets and its
principal methods of competition in various markets include service, price and
quality. No material part of the business is dependent upon a single customer or
a few customers and therefore vulnerability from this aspect is not a factor.
However, certain of the Company's business units sell primarily to automotive or
petro-chemical companies.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Financial Statements

     The consolidated financial statements comprise those of the Company and its
subsidiaries. All intercompany balances and transactions have been eliminated.
Certain amounts for 1997 and 1998 have been reclassified to conform with 1999
classifications.

     Inventories and Accounts Receivable

     Inventories are stated at lower of cost or market. Approximately 95% of raw
materials, including raw materials in work in process and finished goods
inventories, is valued by using the last-in, first-out method. Labor and burden
in inventory are determined by using the average cost method. Inventories
relating to equipment contracts are stated at the accumulated cost of material,
labor and burden less related progress billings.

     Revenue from the Company's equipment contracts is recognized using the
percentage-of-completion method except when use of the completed contract method
does not have a material impact on the results of operations.

     For sales reported under the percentage of completion method, the percent
of revenues is recognized based on the ratio of costs incurred to date to total
costs expected for each project. Revenue recognized for jobs in process at
December 31, 1999 totals $370,371 and costs incurred on these contracts amounts
to $247,080. Included in accounts receivable is $161,464 that has not been
billed to customers due to contractual arrangements.

     Land, Buildings and Equipment

     Land, buildings and equipment are stated at cost. Depreciation and
amortization are provided over the estimated useful lives of the assets using
the straight-line method for financial reporting purposes. Leased equipment is
amortized over the lease term or estimated useful life of the asset.

     Annual depreciation rates are as follows:

<TABLE>
<S>                                          <C>
Buildings................................    2.5-20%
Leasehold improvements...................    2.5-20%
Yard facilities..........................    5-6 2/3%
Machinery and equipment..................    6 2/3-33 1/3%
Office furniture and fixtures............     10-25%
</TABLE>

     Interest incurred during construction periods is capitalized. $18,955 was
capitalized in 1998.

     Research and Development

     Research and development costs are charged to operations as incurred.
Research and development costs for 1999, 1998 and 1997 were approximately
$1,286,000, $1,243,000, and $1,365,000, respectively.

     Earnings (Loss) Per Common Share

     Basic earnings (loss) per common share is based upon the average number of
common shares outstanding during the year. Shares subject to in-the-money stock
options are the only items impacting diluted earnings per share.

     Cash Flows

     For purposes of the consolidated statements of cash flows, cash equivalents
are defined as short-term highly-liquid investments with a maturity of three
months or less at date of purchase.

     Fair Value of Financial Instruments

     The carrying values of cash and cash equivalents, accounts receivable,
notes receivable, accounts payable, debt under the Revolving Credit Agreement,
and the Industrial Development Bonds approximated fair values.

     Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities as of the balance sheet date and
the reported amounts of revenues and expenses during the

                                        7
<PAGE>   11

reporting period. Actual results could differ from those estimates.

3. INVENTORIES

     Inventories at December 31 consist of the following:

</TABLE>

     The excess of current cost over the stated last-in, first-out value is
approximately $572,000 and $450,000 at December 31, 1999 and 1998.

5. REVOLVING CREDIT AGREEMENT AND TERM LOAN

     The Company has a Credit Agreement (the Agreement) with Comerica Bank with
a current expiration date of May 1, 2001. As of December 31, 1999 the Agreement
provided for a credit facility of up to $12.0 million, collateralized by the
Company's inventory, accounts receivable, certain fixed assets, and stock of
subsidiaries. The Agreement contains, among other provisions, requirements for
maintaining defined levels of tangible net worth and various financial statement
ratios. Interest under the Agreement was prime interest rate plus 1/4%. The
Agreement also provided for a $2.0 million term loan facility at an interest
rate of prime plus 3/4%. At December 31, 1999, the outstanding balance under the
term loan was $1,668,775, of which $1,302,775 is included in long-term debt and
$366,000 is included in current portion of long-term debt.

     The weighted average interest rate for short term borrowings under the
Agreement for the year ended December 31, 1999 was 8.35%, compared to 8.77% for
the year ended December 31, 1998 and 9.92% for the year ended December 31, 1997.

     At December 31, 1999, the Company was not in compliance with certain
financial covenants contained in the Agreement. The terms of the facility were
subsequently amended retroactive to December 31, 1999, and the Company is in
compliance with the amended covenants. The Company expects to be in compliance
with the amended Agreement throughout 2000. The amendment to the Agreement
increased the facility to $13.0 million and increased the interest rate on the
revolving credit facility to prime plus  3/4% and the interest on the term loan
facility to prime plus 1%.

6. INDUSTRIAL DEVELOPMENT BONDS

     In connection with the expansion of Harvel Plastics, Inc.'s manufacturing
capacity, $4.0 million of industrial development bonds were issued by the
California Economic Development Financial Authority on March 24, 1998. Interest
rates for these bonds are established weekly based on tax-exempt bond interest
rates. The rate at the end of 1999 was 4.9%. The obligation is backed by a
Letter of Credit issued by Comerica Bank for the total amount of the bonds. The
Letter of Credit is in effect until January 2006 and affords protection against
failed remarketing efforts if any were to occur. The amount and timing of
redemption of the bonds is as follows:

<TABLE>

</TABLE>

     In 1995, the Company established a valuation allowance of $467,000 against
its deferred tax assets. The Company returned this reserve to income in 1997.

9. PROPERTY TRANSACTIONS

     In March 1999, the Company sold its idle plant in Bowling Green, Kentucky.
Also in March, another plant facility was converted to a warehouse and written
down to net realizable value and is now included with Other Assets on the
Balance Sheet. The net result of all property transactions for the year was a
before tax gain of $285,039.

     In December 1999, the Company announced the closing of its lubricant
additives plant located on leased property outside of Cincinnati, Ohio. The
manufacturing operations previously conducted there were transferred to the
Company's new facility in Ashtabula, Ohio. As a result of the consolidation, The
Elco Corporation accrued a one-time before tax charge of $637,000 in the fourth
quarter.

10. PENSION AND POSTRETIREMENT COSTS

     The Company and its subsidiaries have several non-contributory, defined
benefit pension plans which cover substantially all employees. Benefits for
salaried employees are based on years of service and the employee's average
monthly compensation using the highest five consecutive years preceding
retirement. Benefits for hourly employees are generally based on a specified
payment per month for each year of service. The Company's funding policy is to
contribute amounts sufficient to provide for benefits earned to date and those
expected to be earned in the future.

     The discount rate and rate of increase in future compensation levels used
in determining the actuarial present value of the projected benefit obligations
were 7.75% and 4.0%, at December 31, 1999, 6.75% and 4.0% at December 31, 1998
and 7.0% and 4.0% at December 31, 1997. The expected long-term rate of return on
assets was 8.5% in 1997 and 9.25% in 1998 and 1999. The following tables set
forth the information required under Statement of Financial Accounting Standards
No. 132:

(1) Includes prescription drugs in 1999

     For measurement purposes, a 6.25% annual rate of increase in the per capita
cost of covered health care benefits (other than prescription drugs where the
rate was 7.04%) was assumed for 1999. The rate is assumed to decrease gradually
over the next 3 years to 4.75% in 2002 and thereafter. The assumption for the
health care cost trend rate has a significant effect on the amount of the
obligation and periodic cost reported. An increase in the assumed health care
cost trend rates by 1.0% in each year would increase the accumulated
postretirement benefit obligation as of December 31, 1999 by approximately 14.1%
and the aggregate of the service and interest cost components of net periodic
postretirement benefit cost for the year then ended by approximately 19.7%.

     The assumed discount rate used in determining the accumulated
postretirement benefit obligation was 7.75% at December 31, 1999, 6.75% at
December 31, 1998 and 7.0% at December 31, 1997.

11. CONTINGENCIES

     The Company and at least seventeen other companies are potentially
responsible for sharing the costs in a proceeding to clean up contaminated
sediments in the Fields Brook watershed in Ashtabula, Ohio. The Environmental
Protection Agency ('EPA") issued a Record of Decision in 1986 concerning the
methods it recommends using to accomplish this task. The Company and the other
potentially responsible parties negotiated with the EPA as to how best to effect
the clean up operation. After negotiation, an agreement was reached with EPA on
clean-up methodology. The Company's share of future costs is anticipated to be
approximately $2.5 million.

     The Company maintains a reserve for anticipated expenditures over the next
several years in connection with remedial investigations, feasibility studies,
remedial design, and remediation relating to the clean up of environmental
contamination at several sites, including properties owned by the Company. The
amounts of the reserve at December 31, 1999 and 1998 were $7.3 million and $8.0
million respectively. The reserve includes a provision for the Company's
anticipated share of remediation in the Fields Brook watershed referred to
above, as well as a provision for costs that are expected to be incurred in
connection with remediation of other sites. Some of these studies have been
completed; others are ongoing. In some cases, the methods of remediation remain
to be agreed upon.

                                       10
<PAGE>   14

     The Company expects to continue to incur professional fees, expenses and
capital expenditures in connection with its environmental compliance efforts. In
addition to the above, there are several other claims and lawsuits pending
against the Company and its subsidiaries. One of those lawsuits involves the
division of costs between several potentially responsible companies for
reimbursement to the EPA for costs it incurred to conduct environmental
remediation at a drum and barrel recycler, which the Company had utilized in the
late 1980's. The potentially responsible companies entered into an Agreement to,
among other things, jointly defend the cost claims of the EPA. A dispute arose
amongst the potentially responsible companies over the Agreement which resulted
in the filing of a lawsuit. The matter went to trial before a jury in June of
1999 and a judgment was entered against the Company in the amount of
approximately $750,000, plus interest and attorney fees. The Company is taking
an appeal to the Michigan Court of Appeals and believes it has reasonable
grounds to seek reversal of the judgment.

     The amount of liability to the Company with respect to costs of remediation
of contamination of the Fields Brook watershed and of other sites, and the
amount of liability with respect to several other claims and lawsuits against
the Company, was based on available data. The Company has established its
reserves in accordance with its interpretation of the principles outlined in
Statement of Financial Accounting Standards No. 5 and Securities and Exchange
Commission Staff Accounting Bulletin No. 92. In the event that any additional
accruals should be required in the future with respect to such matters, the
amounts of such additional accruals could have a material impact on the results
of operations to be reported for a specific accounting period but should not
have a material impact on the Company's consolidated financial position.

12. PREFERRED STOCK

     The Company has authorized 1,000,000 shares of $2 par value preferred
stock, issuable in series. No shares were issued or outstanding as of December
31, 1999, 1998 and 1997.

13. STOCK PURCHASE RIGHTS
     The Company has in place a Shareholder Rights Plan, under which preferred
stock purchase rights were distributed to shareholders as a dividend of one
Right for each outstanding share of Common Stock. Each Right will entitle
shareholders to buy one one-hundredth of a newly issued share of Series A
Preferred Stock of the Company at an exercise price of $80, subject to
adjustment. The Rights will be exercisable only if a person or group acquires
beneficial ownership of 15% or more of the Company's outstanding Common Stock or
commences a tender or exchange offer upon consummation of which a person or
group would beneficially own 30% or more of the Company's outstanding Common
Stock. Until they become exercisable, the Rights will be evidenced by the Common
Stock certificates and will be transferred only with such certificates.

     If any person or group becomes the beneficial owner of 15% or more of the
Company's outstanding Common Stock, or if a holder of 15% or more of the
Company's Common Stock engages in certain self-dealing transactions or a merger
transaction in which the Company is the surviving corporation and its Common
Stock remains outstanding, then each Right not owned by such person or certain
related parties will entitle its holder to purchase, at the Right's then-current
exercise price, shares of the Company's Common Stock (or, in certain
circumstances, units of the Company's Series A Preferred Stock, cash, property
or other securities of the Company) having a market value equal to twice the
then-current exercise price. In addition, if after a person or group becomes the
beneficial owner of 15% or more of the Company's outstanding Common Stock the
Company is involved in a merger or other business combination transaction with
another person after which its Common Stock does not remain outstanding, or
sells 50% or more of its assets or earning power to another person, each Right
will entitle its holder to purchase, at the Right's then-current exercise price,
shares of common stock of such other person having a market value equal to twice
the then-current exercise price. The Company will generally be entitled to
redeem the Rights at $.01 per Right at any time until the tenth business day
following public announcement that a person or group has acquired 15% or more of
the Company's Common Stock. The Plan will expire on May 4, 2000 unless the
Rights are earlier redeemed by the Company.

14. STOCK OPTIONS

     On April 22, 1993, the shareholders of the Company approved the
Corporation's 1993 Stock Option Plan (the Management Plan) and the Corporation's
1993 Stock Option Plan for Outside Directors (the Directors Plan). A summary of
the fixed stock option grants under Detrex's Management Plan and Directors Plan
as of December 31, 1999, 1998 and 1997, and changes during the years is
presented below.

     The total number of shares reserved for issuance upon exercise of options
under the Management Plan is 150,000 shares and under the Directors Plan is
50,000 shares. Of the 200,000 options reserved, 6,000 remain available for
future grants under the Management Plan; the time for granting options under the
Directors Plan has expired.

     In accordance with the Statement of Financial Accounting Standard No. 123,
Accounting for Stock-Based Compensation, the Company has elected to continue to
report compensation by applying the requirements of Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees and therefore has
recorded no charge to income for stock options. The pro-forma effect of applying
the Black-Scholes option valuation model as well as the underlying weighted
average Black-Scholes assumptions are as follows:

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

     Detrex Corporation and its consolidated subsidiaries (the "Company")
incurred a loss of $1.1 million in 1999. Three of the Company's business units
had operating income in 1999 while the other two had operating losses. A
business sold in 1999 incurred a loss of $1.0 million before tax.

     Harvel Plastics, Inc. ("Harvel") had significantly higher revenue than in
1998 as a result of strong demand in the building industry and the ability to
service new markets from its new California manufacturing facility. However,
earnings were down in the first half of the year due to higher raw material
costs that were not completely recovered in price and costs incurred in
launching its new plant. The Elco Corporation ("Elco") had approximately the
same revenue as in 1998. Elco's earnings were adversely affected by a $637,000
charge resulting from the closing of its lubricant additives plant located
outside of Cincinnati, Ohio and costs incurred prior to transferring
manufacturing operations to its new facility in Ashtabula, Ohio.
Seibert-Oxidermo, Inc. ("Seibert") reported a profit in 1999 compared to a loss
in 1998. This improvement occurred from strong automotive demand and volume
increases from new accounts, combined with efficiencies achieved by
consolidating manufacturing operations. The Equipment Division continued to lose
money as the weakness in the cleaning equipment market stretched into 1999. The
loss was smaller than in 1998 as cost reduction measures were taken. Sales in
the Solvents Division were approximately the same as in 1998, but sales in low
margin product lines resulted in a loss for 1999.

     1999 Compared to 1998 -- Net sales in 1999 for the Company reflect a $4.4
million increase from the previous year. As indicated above, Harvel benefitted
from strong demand in the building industry and having a new manufacturing
operation in California to meet the increased demand. Harvel's sales increase on
a year-to-year basis was $6.0 million. Seibert had a $1.3 million increase in
sales as a result of new business coming on stream. Sales for Elco and the
Solvents Division were approximately the same as last year while Equipment
Division sales decreased by $2.0 million.

     Gross margin in 1999 was 22.9% compared to 24.7% in 1998. The major reasons
for the decline were costs involved in closing a plant of Elco's and costs
associated with a business that was sold. In addition Harvel incurred a
reduction in margins as the price of raw materials increased. Solvents Division
incurred a reduction in margin as a result of unfavorable product mix and
offshore competition while Seibert's margins increased due to mix.

     Selling, general and administrative expenses were approximately the same in
1999 and 1998. Economic increases averaging 4% occurred in all of the Company's
operating units but productivity improvements offset most of the economics.
Expenses were 20.1% of sales in 1999, compared to 21.0% of sales in 1998.

     The provision for depreciation and amortization is higher than 1998 as a
result of depreciation of new plants in Ashtabula, Ohio and Bakersfield,
California, and the new management information system at the Corporate
headquarters.

     Interest expense is higher in 1999 due to increased borrowings and higher
interest rates from a year ago.

     The income tax credit in both 1999 and 1998 reflects credits for federal
income tax, partially offset by state and local income tax expense.

     1998 Compared to 1997 -- Net sales in 1998 reflect a $9.7 million decrease
from the previous year. The largest decrease was in the Company's Equipment
Division as a result of reduced capital spending by customers in the markets we
serve. Decreases also occurred at Elco, Seibert, and the Company's Solvents
Division. During 1998, these business units were adversely affected by the

economic situation in Asia, the slowdown in computer chip manufacturing, and the
General Motors strike. Sales at Harvel were approximately the same as the
previous year.

     Gross margin in 1998 was 24.7%, compared to 25.5% in 1997. Margins were
adversely affected by the drop in volume and pricing pressure. Margins at Harvel
were also affected by launch costs at its new California manufacturing facility.
As a result of launching the California operations, Harvel's inventory and
manpower were both higher than December 31, 1997 levels.

     The year-to-year increase in selling, general and administrative expenses
is due to economic increases in all of the Company's operating units,
termination and severance costs, and additional marketing and technical support
personnel in some of the Company's business units. These increases more than
offset the increase in pension credits.

     The provision for depreciation and amortization is higher than a year ago
as a result of depreciation of plant additions in Ashtabula, Ohio and partial
year depreciation of equipment at Harvel's new facility in California.

     Interest expense on bank borrowings is approximately $31,000 lower than
last year due to lower rates being negotiated at the time the Company's Credit
Agreement was extended. However, interest expense in 1998 also includes interest
attributable to the tax deferral of income from certain export sales and two
months of interest on Harvel's industrial development bonds. Also, more interest
was capitalized in 1997 than in 1998. The total year-to-year change in interest
expense is an increase of $57,000.

     The income tax credit in 1998 reflects a credit for federal income tax,
partially offset by state and local income tax expense. Income tax expense in
1997 reflects state, local and federal income taxes, partially offset by
returning to income the deferred tax valuation allowance that was established in
1995.

LIQUIDITY, FINANCIAL CONDITION, AND CAPITAL RESOURCES

     The Company utilized internally generated funds, the proceeds from the sale
of a closed plant and increased borrowings to finance operating activities and
$5.3 million in capital expenditures during 1999. The Company's borrowings under
its revolving credit facility increased by $2.0 million during the year bringing
the loan balance at December 31st to $8.3 million. The loan balance under the
Company's equipment facility was $1.7 million.

     The Company's capital expenditures for 2000 are estimated to be $3.5
million. It is anticipated that these expenditures will principally be financed
through internally generated funds and borrowings under existing financing
arrangements.

     On February 29, 2000, the Company amended its Agreement with Comerica Bank
increasing the revolving credit facility to $13.0 million. The financial
covenants were amended retroactive to December 31, 1999 and the interest rate on
the revolving credit facility was increased by 1/2% and the interest rate on the
term loan facility was increased by 1/4%.

     Working capital was $3.7 million at December 31, 1999 compared to $5.9
million at December 31, 1998. The Company has paid no dividends since the second
quarter of 1991 and cannot forecast when the dividend will be restored.

OTHER

     The Company has not completed the process of evaluating the impact that
will result from adopting Statement of Financial Accounting Standards No. 133,
Accounting for Derivative Instruments and Hedging Activities. The Company is
therefore unable to disclose the impact that adopting Statement of Financial
Accounting Standards No. 133 will have on its financial position and results of
operations when such statement is adopted.

     The Company completed its work to ensure compliance with Y2K issues on a
timely basis and has not encountered any difficulties in this area.
