Consolidated Financial Statements

  The consolidated balance sheet at June 30, 1999 and the consolidated
statements of income for the three months and six months ended June 30, 1999 and
1998, and the consolidated statements of cash flows for the six months ended
June 30, 1999 and 1998, are unaudited, but include all adjustments (consisting
only of normal and recurring accruals) which the Company considers necessary for
fair presentation.

  The accompanying consolidated financial statements do not include all
disclosures normally provided in annual financial statements and, therefore,
should be read in conjunction with the year-end financial statements.

  The Company's line of credit was increased to $33 million on May 20, 1999 to
fund the start-up of the reclamation processing plant in Muskogee, Oklahoma. The
revolving line of credit expires on May 20, 2002. The credit lines are currently
being used for letters of credit needed for funding assurance related to
environmental issues, insurance policies, and development loans. Total unused
lines of credit were $24.9 million as of June 30, 1999.

 The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

 As of January 1, 1998, the Company adopted Statement of Financial Accounting
Standards No. 130, Reporting Comprehensive Income. Statement 130 establishes new
rules for the reporting and display of comprehensive income and its components;
however, adoption of this Statement has no impact on net income or shareholders'
equity. Statement 130 requires unrealized gains or losses on available-for-sale
securities and foreign currency translation adjustments, which prior to adoption
were reported separately in shareholders' equity, to be included in other
comprehensive income. For the six months ended June 30, 1999 total comprehensive
income was $1,595 more than net income due to foreign currency translation
gains. For the six months ended June 30, 1998 total comprehensive income was
equal to net income.

  In 1998, the Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," which changes the way the Company reports
information about its operating segments in annual financial statements and also
requires selected segment information in interim reports to shareholders. The
information for 1998 has been restated from the prior years' presentation in
order to conform to the 1999 presentation. The Company's business units have
separate management teams and infrastructures that offer different products and
services.

   The following Management's Discussion and Analysis of Financial Condition and
Results of Operations may contain various "forward-looking statements" within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended, which can be
identified by the use of forward-looking terminology such as "believes",
"expects", "prospects", "estimated", "should", "may" or the negative thereof or
other variations thereon or comparable terminology indicating the Company's
expectations or beliefs concerning future events.  The Company cautions that
such statements are qualified by important factors that could cause actual
results to differ materially from those in the forward-looking statements, a
number of which are identified in the discussion which follows.  Other factors
could also cause actual results to differ materially from expected results
included in these statements.

   The following discussion should be read in conjunction with the consolidated
financial statements of the Company and the related notes to the consolidated
financial statements.

Quarter Ended June 30, 1999 Compared to Quarter Ended June 30, 1998

  Second quarter, 1999 net sales for Fansteel were $38,226,000, a decrease of
$1,418,000, or 3.6%, from the second quarter net sales of $39,644,000 for 1998.
  Operating income for the Company was $2,398,000 for the second quarter of 1999
compared to $2,351,000 in the second quarter of 1998, an increase of $47,000.
Lower material costs, reduced manufacturing costs, and the full production of
the Fansteel de Mexico operation provided improvment to operating income despite
the lower sales volume.

  The Company incurred other expenses of $61,000 in the second quarter of 1999
compared to other income of $212,000 in the second quarter of 1998. Interest
income in the current quarter was lower due to less cash being available for
investment due to expenditures for start-up of Fansteel de Mexico and the
reclamation plant in Muskogee, Oklahoma. Second quarter results in 1998 included
nonrecurring gains of $137,000 for the sale of excess land.

  Net income for the second quarter of 1999 was $1,573,000, or $.18 per share,
compared to $1,621,000, or $.19 per share, for the same period of the prior
year. Net income as a percentage of sales of 4.1% for the second quarter of 1999
remained the same as the second quarter of 1998. The effective tax rate was
lower in the second quarter of 1999 compared to the second quarter of 1998 due
to the reduction in the valuation allowance for deferred taxes related to
environmental reserves which had a favorable impact on second quarter, 1999 net
income of $.01 per share.

  Industrial Tools business segment net sales for the second quarter of 1999
were $14,362,000 compared to $15,102,000 in the second quarter of 1998, a
decrease of $740,000, or 4.9%. Most of this decline was due to lower tungsten
carbide cutting tool sales to the metalworking industry, which has experienced a
downturn since the third quarter of 1998. Sales of wear parts also declined,
mainly for downhole drilling products, due to the depressed oil industry.
Partially offsetting these declines were road construction tool sales, which
posted its highest quarter of the decade. Coal mining tools showed a slight
improvement in the second quarter of 1999 compared to the second quarter of
1998.

  Industrial Tools operating income for the second quarter of 1999 was
$1,175,000 compared to $958,000 in the same period of 1998, an increase of

                  ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS        Form 10-Q
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS         Page 10


$217,000. As a percentage of net sales, Industrial Tools operating income was
8.2% for the current quarter compared to 6.3% for the same period of the prior
year. Despite the sales decline in this segment, operating income benefited from
lower material costs and reduced manufacturing costs.

  Advanced Structures business segment net sales for the second quarter of 1999
were $12,819,000, a decrease of 6.6%, from second quarter 1998 net sales of
$13,731,000. Forging sales declined as a result of reduced order rates, order
push-outs, and inefficiencies caused by downtime during necessary equipment
repairs. Sales of machined aircraft parts suffered from excess inventory at key
customers. Sales of sand castings improved for the second quarter of 1999
compared to the same period of the prior year as a result of increased orders
for tooling.

  Advanced Structures operating income decreased by $405,000 from the second
quarter of 1998 to $437,000 in the second quarter of 1999. As a percentage of
net sales, operating income was 3.4% for the current quarter compared to 6.1% in
the same period last year. Operating income for the current quarter was lower
than last year as a result of lower sales volume and due to production
inefficiencies at the forging operation which resulted from downtime during
machine repairs and from capacity problems on the current steam delivery system.
The steam system is being upgraded and replaced concurrently with a new system
which is scheduled to be fully operational during the third quarter of 1999.

  Industrial Metal Components business segment net sales for the second quarter
of 1999 were $11,046,000, an increase of 2.2% from second quarter, 1998 net
sales of $10,810,000. Increased capacity from the Fansteel de Mexico operation
allowed for increased investment castings sales to the medium-duty truck market
and the marine industry. Wire formed product sales declined over its record high
second quarter in 1998, with the decrease coming primarily from the lawn and
garden equipment market. The powdered metal market showed signs of
strengthening, and as a result, sales of powdered metal components increased in
the second quarter of 1999 compared to the same period in 1998.

  Operating income for the Industrial Metal Components for the second quarter of
1999 was $798,000, an increase of $236,000 from $562,000 for the same period of
1998. As a percentage of net sales, operating income was 7.2% for the second
quarter of 1999 compared to 5.2% in the same period last year. Results in the
second quarter of 1998 were impacted by capacity constraints at the investment
casting facility caused by ramping up production quickly to meet escalating
demand while maintaining on-time deliveries. The capacity situation was
alleviated through the Fansteel de Mexico facility as full production was
achieved in the second quarter of 1999. This resulted in lower operating costs
in the current quarter compared to the same period of the prior year.



Six Months Ended June 30, 1999 Compared to the Six Months Ended June 30, 1998

  The Company's net sales of $75,272,000 for the first half of 1999 decreased by
$4,161,000, or 5.2%, from the same period of 1998.

  Operating income for Fansteel in the first half of 1999 was $3,921,000
compared to $5,016,000 in the first six months of 1998, a decrease of
$1,095,000, or 21.8%. The decrease resulted from the lower sales volume and a
one-time charge in the first quarter of 1999 related to management changes.

                  ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS        Form 10-Q
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS         Page 11


  Other expenses of $111,000 for the Company were incurred in the first half
of 1999 compared to other income of $313,000 in the first half of 1998. Interest
income was lower in 1999 due to less cash being available for investment due to
expenditures for the start-up of Fansteel de Mexico and continued expenditures
for the reclamation plant in Muskogee, Oklahoma. Results in 1998 included
nonrecurring gains of $137,000 for the sale of excess land.

  Net income for the first six months of 1999 was $2,586,000 or $.30 per share
compared to $3,350,000 or $.39 per share for the same period of 1998. One-time
charges related to management changes in the first quarter of 1999 decreased

earnings by $.04 per share for the first half of 1999. The effective tax rate
was lower in the first half of 1999 compared to the same period of the prior
year due to the reduction in the valuation allowance for deferred taxes related
to environmental reserves which had a favorable impact on net income in 1999 of
$.02 per share.

  Net sales for the Industrial Tools business segment for the first six months
of 1999 were $28,022,000 compared to $30,451,000 for the same period of 1998, a
decrease of $2,429,000, or 8.0%. Tungsten carbide cutting tool sales slowed in
the second half of 1998 and have not regained their previous strength. Wear part
sales have also declined, particularly for downhole drilling products where the
oil industry has suffered from low oil prices. Construction tool sales improved
due to strong demand for the new pyramid-tipped construction tool and the high
level of activity in road construction programs. Coal mining tool sales
benefited from the addition of a key distributor at the end of the second
quarter of 1998.

  Industrial Tools operating income for the first six months of 1999 was
$2,345,000, an increase of $242,000, or $11.5%, compared to the $2,103,000 for
the same period of 1998. As a percentage of net sales, operating income was 8.4%
for the first half of 1999 compared to 6.9% in the same period of the prior
year. Despite the decline in sales, operating income improved due to lower
material costs which were offset partially by higher selling and administrative
costs in relation to sales.

  Advanced Structures business segment net sales for the first six months of
1999 were $25,086,000, a decrease of 10.1% compared to $27,898,000 in the first
half of 1998. Sales of forgings declined due to reduced order rates and order
push-outs from the major airline manufacturers. Sales of magnesium and aluminum
sand casting tooling products have improved, but casting product sales have
declined as customers have utilized their current inventories.

  Advanced Structures operating income for the first half of 1999 was $769,000
compared to $1,730,000 for the same period of 1998. As a percentage of net
sales, operating income for the six months ended June 30, 1999 fell to 3.1%
compared to 6.2% for the same period of the prior year. Operating income as a
percentage of sales was negatively impacted by inefficiencies related to
equipment utilization.

  Industrial Metal Components business segment net sales for the first six
months of 1999 were $22,164,000, an increase of 5.1% compared to $21,084,000 in
the first half of 1998. Additional capacity from Fansteel de Mexico allowed for
increased investment casting sales of engine components for the medium-duty
truck industry as well as the addition of parts for the marine industry. After
its two strongest quarters ever in the first half of 1998, wire formed product
sales declined in the first half of 1999, primarily in the lawn and garden
market. Sales of powdered metal components declined, with the effects of
customer inventory adjustments impacting the first quarter of 1999.

                  ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS        Form 10-Q
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS         Page 12

  Industrial Metal Components operating income for the first half of 1999 was
$1,325,000, an increase of $114,000 compared $1,211,000 in the same period of
1998. As a percentage of net sales, operating income for the first half of 1999
improved to 6.0% from 5.7% in the same period of the prior year. Improvement
to operating income resulted from lower operating costs associated with full
production at the Fansteel de Mexico facility.

  Order backlog at June 30, 1999 was $51,431,000, a decrease of $8,720,000, or
14.5%, from June 30, 1998. Advanced Structures backlog was most negatively
impacted due to reduced orders for forgings from aircraft manufacturers. The
Industrial Tools backlog declined due to the continued effects of the slowdown
in the metal working industry. Order backlog for Industrial Metal Components
backlogs decreased primarily due a decline in orders from the lawn and garden
industry.

Outlook

  Sales and order rates in a number of key markets including metalworking and
the commercial aircraft market experienced decreases in the last half of 1998
compared to the first half of 1998. In the first half of 1999, these markets
remained at the second half of 1998 level. Growth in 1999 compared to the second
half of 1998 will depend on opportunities from improvements in the Company's
production processes, new product development, and investment in capital
equipment. The Company is seeking increased share of current markets, as well as
new markets, through investment in current operating units, such as the 1998
Fansteel de Mexico start-up which began full production in 1999. Cost control
programs remain active in all operating plans throughout the Company.


Liquidity and Capital Resources

   Cash and cash equivalents amounted to $193,000 at June 30, 1999, a decrease
of $1,839,000 from December 31, 1998. Investments in plant and equipment at
operating locations totaled $1,363,000, in accordance with management's program
to expand the operations of the Company. Engineering, equipment and start-up
costs of $5,718,000 were incurred for the processing plant being built for
reclamation and decommissioning purposes in Muskogee, Oklahoma.

   In the fourth quarter of 1995, the Company announced the suspension of the
quarterly shareholder dividend for the purpose of conserving cash for capital
reinvestment, possible future acquisitions, and due to potential changes in
funding requirements for decommissioning at the Company's discontinued operation
in Muskogee, Oklahoma.

   Cash, cash equivalents and marketable securities on hand have been sufficient
to date to meet the demands of increased working capital investments,
expenditures for machinery and equipment, environmental costs and other normal
operating requirements. However, the Company's line of credit was increased to
$33 million on May 20, 1999. This agreement expires May 20, 2002. As of June 30,
1999, there were no borrowings from the revolving line of credit, but $8.1
million was being used for letters of credit needed for funding assurance
related to environmental issues, self-insurance policies and development loans.
The Company expects to further use a portion of this unused credit during 1999
to fund the start-up of the reclamation processing plant in Muskogee.

   Funding assistance by states and municipalities is investigated when any
significant expenditures are proposed.  All of the Company's debt is related to
development loans obtained from various states.

Environmental Remediation and Discontinued Operations

   The Company discontinued its Metal Products business segment in 1989.
Environmental reclamation and decommissioning is required for the segment's
primary plant that processed certain ores which are subject to regulations of
several government agencies. The residues from these processed ores were stored
on-site. Remaining assets were written down to estimated realizable value, and
provisions were made for the estimated costs for decommissioning. The Company,
in association with outside consultants, has developed a decommissioning plan
for the site involved, and has submitted that plan and a related decommissioning
funding plan to the Nuclear Regulatory Commission ("NRC") as required by law.

   Prior to decommissioning, the Company will construct and operate for
approximately ten years a commercial plant to complete the processing of
residues currently contained in storage ponds at the site, which will materially
reduce the amount of radioactive materials to be disposed of during

decommissioning. In conjunction with construction of the processing plant, the
Company will modify the wastewater treatment plant at the site and install a
drainage system. Decommissioning would include construction of an engineered
on-site cell for containment of contaminated soils; consolidation and
stabilization of the contaminated soils in the containment cell; and the
performance of required plant surveys and characterizations after residue
processing ceases to determine whether additional contaminated soils exist which
may require remediation.

   The Company has received an amendment to its current NRC license and a
revision to its current wastewater discharge permit to allow for the
construction and operation of the processing plant. Construction is nearly
completed on the processing plant which will extract commercially valuable
materials such as tantalum, columbium, scandium and other rare earth and rare
metal elements from the feedstock residues. The construction phase is in the
final stages and processing of residues had been scheduled to begin in the
second quarter of 1999. However, processing was delayed after the plant suffered
tornado damages in the beginning of June. All essential repairs, which were
covered by insurance, have been completed with initial product now expected to
be processed in the third quarter of 1999.

   At June 30, 1999 the Company had recorded liabilities of $9.3 million for
discontinued operations including the estimated net costs of reclaiming and
decommissioning the site during and after the approximate ten years of
processing the residues described above. An additional provision for
discontinued operations of $7.1 million was recorded in 1997 to increase the
established liabilities for the estimated cost of additional studies which may
be required by regulatory agencies, higher start-up costs, and potentially
greater disposal costs after completion of the residue processing period, as
well as for cost estimates related to probable future environmental remediation
at a second site which had been part of the Metal Products business segment. The
second site is regulated under the Resource Conservation and Recovery Act and,
as a result of alleged migration of contaminants from this second site, the
Company also has been identified as a potentially responsible party under the
Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) at
a neighboring third-party site.

   The estimated net costs of reclaiming and decommissioning the first site
during the residue processing period include estimated annual revenues of

                  ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS        Form 10-Q
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS         Page 14


approximately $8 million per year over the ten year processing period and
estimated annual operating costs, including depreciation, of approximately the
same amount, related to residue processing. The estimated value of materials to
be extracted is based on analysis of samples taken from the residues and a
valuation of such materials using current market prices discounted to reflect
possible price decreases, including those which could result from the increased
quantities of certain of these materials made available for sale. However, there
can be no assurance as to the level of demand for the extracted materials or the
actual prices which may be obtained for them, which could vary over time. The
estimated costs of residue processing were developed by Company personnel and
independent consultants using third-party evaluations based on the pilot testing
performed. Unforeseen production complications could cause processing costs to
increase from current estimates.

   In October 1995 the NRC advised the Company that a decommissioning funding
plan cost estimate based upon on-site disposal of most of the radioactive wastes
at the site was appropriate to consider. The NRC cautioned the Company, however,
that on-site disposal may require preparation of an Environmental Impact
Statement and that, in addition to the required NRC approval, local and other
federal agencies may have to be satisfied that the Company's disposal plan is
sound. Such approval process can be expected to extend over a number of years.
Management believes that a decommissioning plan including on-site containment

will ultimately be acceptable to the appropriate regulatory authorities, based
on current NRC regulations or provisions of the Nuclear Waste Policy Act of
1982. However, there is no assurance that a plan providing for on-site
containment will ultimately be approved. Implementation of a decommissioning
plan for the Company's site which includes off-site disposal may not be
financially feasible.

   The NRC decommissioning regulations require licensees to estimate the cost
for decommissioning and to assure in advance that adequate funds will be
available to cover those costs. NRC regulations identify a number of acceptable
methods for assuring funds for decommissioning, including surety instruments
such as letters of credit, cash deposits and combinations thereof. The NRC
October 1995 letter requested that the Company submit a decommissioning funding
plan contemplating on-site containment and stated that the cost of residue
processing should be included in the Company's cost estimate. In March 1996, the
Company submitted a revised decommissioning plan and related decommissioning
funding plan. The level of assurance for decommissioning is currently $4,456,000
provided through letters of credit. The amount does not include assurance for
costs of construction or operation of the residue processing facility. This
level of assurance, however, may be changed upon further review by the NRC. The
Company's available cash and/or borrowing capacity will be reduced by the amount
of funding assurance as required at any particular time. As the decommissioning
plan is implemented, deposited funds or the amount of any surety instruments may
be reduced, provided the Company can demonstrate the sufficiency of the
remaining funds or surety to assure the completion of decommissioning.

   In addition to the two sites included in the discontinued operations, the
Company has a total of seven sites at other Company facilities where
environmental remediation is ongoing or will be undertaken. Certain of these
sites were identified as a result of environmental studies conducted by the
Company during 1997 at all of its owned sites, including testing of soil and
groundwater at selected sites as indicated by the environmental studies.

   The Company has also been notified that it is a potentially responsible party
at six sites owned by third parties. The Company's participation at four

                  ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS        Form 10-Q
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS         Page 15

sites is de minimis, and at the other two sites the Company is either being
defended by its insurance carriers or has meritorious defenses to liability.

   At June 30, 1999 the Company had recorded liabilities of $8.2 million for
estimated environmental investigatory and remediation costs based upon an
evaluation of currently available facts with respect to each individual site,
including the results of environmental studies and testing conducted in 1997,
and considering existing technology, presently enacted laws and regulations, and
prior experience in remediation of contaminated sites. An additional provision
of $6,900,000 was recorded in 1997 for the estimated potential exposure for such
costs. Actual costs to be incurred in future periods at identified sites may
vary from the estimates, given the inherent uncertainties in evaluating
environmental exposures. Future information and developments will require the
Company to continually reassess the expected impact of these environmental
matters. The Company does not expect that any sums it may have to pay in
connection with these environmental liabilities would have a materially adverse
effect on its consolidated financial position.

Year 2000 Readiness Disclosure

   Many existing information technology ("IT") products and systems and non-IT
products and systems containing embedded processor technology were originally
programmed to represent any date by using six digits (e.g., 12/31/99), as
opposed to eight digits (e.g., 12/31/1999). Accordingly, such products and
systems may experience miscalculations, malfunctions, or disruptions when
attempting to process information containing dates that fall after December 31,
1999 or other dates, such as September 9, 1999 (9/9/99), a date traditionally

used by computer programmers as a default. These potential problems are
collectively referred to as the "Year 2000" problem. The following comments
summarize the Company's overall approach and status with respect to Year 2000
issues.

   The Company has been engaged in an ongoing, comprehensive project to assess
and remediate the impact on its computer systems and programs of the Year 2000
problem. The assessment process began in late 1996 with the inventory of all
potentially affected hardware and software, along with a determination as to
whether or not they may be impacted by the Year 2000. This assessment has been
completed. All affected hardware has been replaced. All software developed
in-house has been reviewed and necessary modifications or replacements are in
process with final testing to be completed by September 1, 1999. The Company has
identified software supplied by outside vendors which is not Year 2000
compliant.  With respect to the critical applications, the Company has acquired
the most recent releases or purchased replacement software which is Year 2000
compliant. Implementation and testing of new releases and new software is
scheduled to be completed by the third quarter of 1999. Non-critical
applications are being reviewed on an on-going basis with revision or
replacement being made as needed.

   The Company began an assessment in 1998 of non-IT products and systems which
may contain embedded processor technology which will not recognize the year 2000
properly. This assessment was completed during the second quarter of 1999. No
significant issues have been identified with non-IT products and systems. All
remedial actions will be completed before year-end.

    The total Year 2000 costs are estimated at approximately $1.2 million, which
includes new hardware, new software and upgrades to existing computer
equipment, as well as training for these new systems. Three or four year
operating leases have been obtained for a majority of the new IT products and
systems, most of which would have been done through normal operations of the

                  ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS        Form 10-Q
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS         Page 16

information systems. Approximately 20% of the total expenditures were made in
1997 with an additional 25% made in 1998, and 20% made in the first half of
1999. A portion of the remaining 35% will be expensed in 1999 with the remainder
being expensed in future years in relation to terms of applicable leases.

   The Company initiated communications using questionnaires with key suppliers
and customers in 1998 to determine the extent to which the Company's interface
systems are vulnerable to those third parties' failure to remediate their own
Year 2000 problems. Key suppliers were determined based upon the amount of
business and the importance to the Company of the material or services provided.
The initial contacts were with financial institutions which provide banking and
employee benefit services. All of those financial institutions have responded by
identifying their plans to become Year 2000 compliant and now provide periodic
reports on their progress.  All key suppliers and customers have also been
contacted using questionnaires. This process will be ongoing throughout the
remainder of 1999 by reviewing responses, obtaining updates, requesting
additional follow-up information, and identifying new key suppliers and
customers. To date, no negative responses have been received, but there is no
guarantee that systems of other companies on which the Company's systems rely
will be converted timely and would not have a material adverse effect on the
Company's systems.

   The Year 2000 project is estimated to be completed in 1999 prior to any
anticipated impact on the Company's IT and non-IT products and systems. The
Company believes that with modifications to existing software and conversions to
new software, the Year 2000 issue will not pose significant operational problems
for its systems. However, if such modifications and conversions are not made or
are not completed in a timely manner, the Year 2000 issue could have a material
impact on the operations of the Company.

   At this time, the Company is unable to determine its most reasonably likely
worst case scenarios as a result of the Year 2000 issue. The Company continues
to analyze possible scenarios as part of the Year 2000 project. An area of
concern which is considered low risk, but potentially high impact would be
widespread long-term utility failures resulting in a shut-down of the Company's
operations. The Company has little ability to correct such a utility failure. At
this time, the Company is unable to determine the impact or likelihood of such a
utility failure. Another area considered by the Company to be low risk and
potentially high impact is the foreign supply of raw materials. The Company has
developed contingency plans to address continued short-term supply of these
materials, but long-term shortages may result in price increases well into the
year 2000. The amount of these price increases and the Company's ability to pass
on such increases to our customers is not determinable at this time. The Company
continues to evaluate all key components of its operations and is developing
related contingency plans as more information becomes available. The Company
believes it will have developed its contingency plans by the fourth quarter of
1999.

   The costs of the project and the date on which the Company believes it will
complete the Year 2000 project are based on management's best estimates, which
were derived utilizing numerous assumptions of future events, including the
continued availability of certain resources and other factors. However, there
can be no guarantee that these estimates will be achieved and actual results
could differ materially from those anticipated. Specific factors that might
cause such material differences include, but are not limited to, the
availability and cost of personnel trained in this area, the ability to locate
and correct all relevant codes, and the level of compliance by key suppliers and
customers.

reduction shall be in an aggregate amount at least equal to $2,000,000 or
integral multiples of $100,000 in excess thereof; (iii) the Commitments less
outstanding L/C Obligations and PEDFA Loans shall not be reduced below the
outstanding principal amount of Loans, L/C Obligations and PEDFA Loans; and (iv)
no such reduction shall cause any Bank's Pro Rata Share of the Commitments less
its Pro Rata Share of L/C Obligations and PEDFA Loans to be reduced below the
outstanding principal amount of Loans made by such Bank and its participation in
the L/C Obligations and PEDFA Loans; and (iv) the L/C Obligations shall not
exceed the L/C Commitment.

          (b)  Commitments once terminated or reduced may not be reinstated.

     2.4. Fees.

          (a)  The Company shall pay to the Agent, for the account of each Bank
(to be paid to each Bank based on its Pro Rata Share of the Commitments), an
annual non-use fee on the average daily amount of such Bank's unused Commitment,
for the period from and including the date of this Agreement to but not
including the earlier of the date such Commitment is terminated or the
Termination Date, at a rate per annum equal to .125%.  The accrued non-use fee
in respect of the Commitments shall be payable in arrears on each Quarterly Date
and on the earlier of the date the Commitments are terminated or the Termination
Date.

          (b)  The Company shall pay to the Agent for the account of each Bank a
non-refundable fee in an amount equal to the product of .125% times the amount
of such Bank's Commitment on the date hereof.  Such fee shall be payable on or
before the date of this Agreement.

          (c)  The Company shall pay to the Agent for the account of the Agent
such fees as shall be set forth in a letter agreement dated the date of this
Agreement between the Agent and the Company.

     2.5. Lending Offices.   The Loans of each type made by each Bank shall be
made and maintained at such Bank's Applicable Lending Office for Loans of such
type.

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


     2.6. Several Obligations; Remedies Independent.   The failure of any Bank
to make any Loan to be made by it or fund its Pro Rata Share of any drawing
under a Letter of Credit on the date specified therefor shall not relieve any
other Bank of its obligation, if any, to make any Loan or fund such drawing on
such date, but neither any Bank nor the Agent shall be responsible for the
failure of any other Bank to make a Loan or fund such drawing to be made by such
other Bank.  The amounts payable by the Company at any time hereunder, under the
Note and the L/C Obligations to each Bank shall be a separate and independent
debt, and each Bank shall be entitled to protect and enforce its rights arising
out of this Agreement, its Note and the L/C Obligations, and it shall not be
necessary for any other Bank or the Agent to consent to, or be joined as an
additional party in, any proceedings for such purposes.

     2.7. Notes.   The Loans made by each Bank shall be evidenced by a
promissory note of the Company in substantially the form of Exhibit A hereto.
The date, amount, and type of each Loan made by each Bank, and each payment made
on account of the principal thereof, shall be recorded by such Bank on its books
and, prior to any transfer of its Note evidencing such Loans held by it,
endorsed by such Bank on the schedule attached to such Note or any continuation
thereof;  provided, however, that any failure to so record or any error in
recording shall not affect the Company's obligations under this Agreement or the

Notes.

     2.8. Voluntary Conversion or Continuation of Loans.   Subject to Section
5.4 hereof, the Company shall have the right to Convert Loans of one type into
Loans of another type or Continue Eurodollar Loans as such at any time, provided
that:  (a) the Company shall give the Agent written notice of each such
Conversion or Continuation as provided in Section 5.5 hereof; and (b) Eurodollar
Loans may be Continued or Converted only on the last day of an Interest Period
for such Loans.

     Section 3.     Letters of Credit.

     3.1. The Letter of Credit Subfacility.   (a) On the terms and conditions
set forth herein (i) the Issuing Lender agrees, from time to time on any
Business Day during the period from the date hereof to the Termination Date to
issue Letters of Credit for the account of the Company, and to amend or renew
Letters of Credit previously issued by it, in accordance with subsections 3.2(b)
and (c) and to honor drafts under the Letters of Credit; and (ii) the Banks
severally agree to participate in Letters of Credit issued for the account of
the Company; provided, that the Issuing Lender shall not be obligated to issue,
and no Bank shall be obligated to participate in, any Letter of Credit if as of
the date of issuance of such Letter of Credit (the "Issuance Date") (A) the
amount of all L/C Obligations plus the amount of all Loans and PEDFA Loans
exceeds the Commitments, (B) the participation of any Bank in the amount of all
L/C Obligations plus the amount of the Loans and PEDFA Loans of such Bank
exceeds such Bank's Pro Rata Share of the Commitments, or (C) the amount of L/C
Obligations exceeds the L/C Commitment.  Within the foregoing limits, and
subject to the other terms and conditions

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999



hereof, the Company's ability to obtain Letters of Credit shall be fully
revolving, and, accordingly, the Company may, during the foregoing period,
obtain Letters of Credit to replace Letters of Credit which have expired or
which have been drawn upon and reimbursed.

     (b)  The Issuing Lender is under no obligation to issue any Letter of
Credit if:

          (i)  any order, judgment or decree of any governmental authority
     or arbitrator shall by its terms purport to enjoin or restrain the
     Issuing Lender from issuing such Letter of Credit, or any requirement
     of law applicable to the Issuing Lender or any request or directive
     (whether or not having the force of law) from any governmental
     authority with jurisdiction over the Issuing Lender shall prohibit, or
     request that the Issuing Lender refrain from, the issuance of letters
     of credit generally or such Letter of Credit in particular or shall
     impose upon the Issuing Lender with respect to such Letter of Credit
     any restriction, reserve or capital requirement (for which the Issuing
     Lender is not otherwise compensated hereunder) not in effect on the
     date hereof, or shall impose upon the Issuing Lender any unreimbursed
     loss, cost or expense which was not applicable on the date hereof and
     which the Issuing Lender in good faith deems material to it;

          (ii) the Issuing Lender has received written notice from any
     Bank, the Agent or the Company, on or prior to the Business Day prior
     to the requested date of issuance of such Letter of Credit, that one
     or more of the applicable conditions contained in Section 7 is not
     then satisfied;

          (iii)the expiry date of any requested Letter of Credit is (1)
     more than 360 days after the date of issuance, unless the Majority
     Banks have approved such expiry date in writing, or (2) after the

     Termination Date, unless all of the Banks have approved such expiry
     date in writing;

          (iv) the expiry date of any requested Letter of Credit is prior
     to the maturity date of any financial obligation to be supported by
     the requested Letter of Credit;

          (v)  any requested Letter of Credit does not provide for drafts,
     or is not otherwise in form and substance acceptable to the Issuing
     Lender, or the issuance of a Letter of Credit shall violate any
     applicable policies of the Issuing Lender;

          (vi) any standby Letter of Credit is for the purpose of
     supporting the issuance of any letter of credit by any other Person;
     or


    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


          (vii)     such Letter of Credit is in a face amount less than
     $250,000 or to be used for a purpose other than in connection with the
     Company's existing lines of business or denominated in a currency
     other than Dollars.

     3.2. Issuance, Amendment and Renewal of Letters of Credit.  (a) Each Letter
of Credit shall be issued upon the irrevocable written request of the Company
received by the Issuing Lender (with a copy sent by the Company to the Agent) at
least four days (or such shorter time as the Issuing Lender may agree in a
particular instance in its sole discretion) prior to the proposed date of
issuance.  Each such request for issuance of a Letter of Credit shall be by
facsimile, confirmed immediately in an original writing, in the form of an L/C
Application, and shall specify in form and detail satisfactory to the Issuing
Lender:  (i) the proposed date of issuance of the Letter of Credit (which shall
be a Business Day); (ii) the face amount of the Letter of Credit; (iii) the
expiry date of the Letter of Credit; (iv) the name and address of the
beneficiary thereof; (v) the documents to be presented by the beneficiary of the
Letter of Credit in case of any drawing thereunder; (vi) the full text of any
certificate to be presented by the beneficiary in case of any drawing
thereunder; and (vii) such other matters as the Issuing Lender may require.

          (b)  At least two Business Days prior to the issuance of any Letter of
Credit, the Issuing Lender will confirm with the Agent (by telephone or in
writing) that the Agent has received a copy of the L/C Application or L/C
Amendment Application from the Company and, if not, the Issuing Lender will
provide the Agent with a copy thereof.  Unless the Issuing Lender has received
notice on or before the second Business Day immediately preceding the date the
Issuing Lender is to issue a requested Letter of Credit from the Agent directing
the Issuing Lender not to issue such Letter of Credit because such issuance is
not then permitted under subsection 3.1(a) as a result of the limitations set
forth in clauses (A) through (C) thereof or subsection 3.1(b)(ii), then, subject
to the terms and conditions hereof, the Issuing Lender shall, on the requested
date, issue a Letter of Credit for the account of the Company in accordance with
the Issuing Lender's usual and customary business practices.

          (c)  From time to time while a Letter of Credit is outstanding and
prior to the Termination Date, the Issuing Lender will, upon the written request
of the Company received by the Issuing Lender (with a copy sent by the Company
to the Agent) at least five days (or such shorter time as the Issuing Lender may
agree in a particular instance in its sole discretion) prior to the proposed
date of amendment, amend any Letter of Credit issued by it.  Each such request
for amendment of a Letter of Credit shall be made by facsimile, confirmed
immediately in an original writing, made in the form of an L/C Amendment
Application and shall specify in form and detail satisfactory to the Issuing
Lender:  (i) the Letter of Credit to be amended; (ii) the proposed date of

amendment of the Letter of Credit (which shall be a Business Day); (iii) the
nature of the proposed amendment; and (iv) such other matters as the Issuing
Lender may require.  The Issuing Lender shall be
    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999



under no obligation to amend any Letter of Credit if: (v) the Issuing Lender
would have no obligation at such time to issue such Letter of Credit in its
amended form under the terms of this Agreement; or (vi) the beneficiary of any
such Letter of Credit does not accept the proposed amendment to the Letter of
Credit.  The Agent will promptly notify the Banks of the receipt by it of any
L/C Application or L/C Amendment Application.

          (d)  The Issuing Lender and the Banks agree that, while a Letter of
Credit is outstanding and prior to the Termination Date, at the option of the
Company and upon the written request of the Company received by the Issuing
Lender (with a copy sent by the Company to the Agent) at least five days (or
such shorter time as the Issuing Lender may agree in a particular instance in
its sole discretion) prior to the proposed date of notification of renewal, the
Issuing Lender shall be entitled to authorize the automatic renewal of any
Letter of Credit issued by it.  Each such request for renewal of a Letter of
Credit shall be made by facsimile, confirmed immediately in an original writing,
in the form of an L/C Amendment Application, and shall specify in form and
detail satisfactory to the Issuing Lender:  (i) the Letter of Credit to be
renewed; (ii) the proposed date of notification of renewal of the Letter of
Credit (which shall be a Business Day); (iii) the revised expiry date of the
Letter of Credit; and (iv) such other matters as the Issuing Lender may require.
The Issuing Lender shall be under no obligation so to renew any Letter of Credit
if: (v) the Issuing Lender would have no obligation at such time to issue or
amend such Letter of Credit in its renewed form under the terms of this
Agreement; or (vi) the beneficiary of any such Letter of Credit does not accept
the proposed renewal of the Letter of Credit.  If any outstanding Letter of
Credit shall provide that it shall be automatically renewed unless the
beneficiary thereof receives notice from the Issuing Lender that such Letter of
Credit shall not be renewed, and if at the time of renewal the Issuing Lender
would be entitled to authorize the automatic renewal of such Letter of Credit in
accordance with this subsection 3.2(d) upon the request of the Company but the
Issuing Lender shall not have received any L/C Amendment Application from the
Company with respect to such renewal or other written direction by the Company
with respect thereto, the Issuing Lender shall nonetheless be permitted to allow
such Letter of Credit to renew, and the Company and the Banks hereby authorize
such renewal, and, accordingly, the Issuing Lender shall be deemed to have
received an L/C Amendment Application from the Company requesting such renewal.

          (e)  The Issuing Lender may, at its election (or as required by the
Agent at the direction of the Majority Banks), deliver any notices of
termination or other communications to any Letter of Credit beneficiary or
transferee, and take any other action as necessary or appropriate, at any time
and from time to time, in order to cause the expiry date of such Letter of
Credit to be a date not later than the Termination Date.

          (f)  This Agreement shall control in the event of any conflict with
any L/C Related Document (other than any Letter of Credit).

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999

          (g)  The Issuing Lender will also deliver to the Agent, concurrently
or promptly following its delivery of a Letter of Credit, or amendment to or
renewal of a Letter of Credit, to an advising bank or a beneficiary, a true and
complete copy of each such Letter of Credit or amendment to or renewal of a
Letter of Credit.

     3.3. Risk Participations, Drawings and Reimbursements.   (a) On and after

the date hereof, the Existing Northern Letters of Credit shall be deemed for
purposes hereof, including for purposes of the fees to be collected pursuant to
subsections 3.8(a) and 3.8(c), and reimbursement of costs and expenses to the
extent provided herein, Letters of Credit outstanding under this Agreement and
entitled to the benefits of this Agreement, and shall be governed by the
applications and agreements pertaining thereto and by this Agreement.  Each Bank
shall be deemed to, and hereby irrevocably and unconditionally agrees to,
purchase from the Issuing Lender on the date hereof a participation in each
Existing Northern Letter of Credit and each drawing thereunder in an amount
equal to the product of (i) such Bank's Pro Rata Share times (ii) the maximum
amount available to be drawn under such Letter of Credit and the amount of such
drawing, respectively.  For purposes of Section 2.1 and subsection 2.4(a), the
Existing Northern Letters of Credit shall be deemed to utilize pro rata the
Commitment of each Bank.

     Immediately upon the issuance of each Letter of Credit, each Bank shall be
deemed to, and hereby irrevocably and unconditionally agrees to, purchase from
the Issuing Lender a participation in such Letter of Credit and each drawing
thereunder in an amount equal to the product of (i) the Pro Rata Share of such
Bank, times (ii) the maximum amount available to be drawn under such Letter of
Credit and the amount of such drawing, respectively.  For purposes of Section
2.1(a), each issuance of a Letter of Credit shall be deemed to utilize the
Commitment of each Bank by an amount equal to the amount of such participation.

          (b)  In the event of any request for a drawing under a Letter of
Credit by the beneficiary or transferee thereof, the Issuing Lender will
promptly notify the Company and the Agent.  The Company shall reimburse the
Issuing Lender prior to 10:00 a.m. Chicago time, on each date that any amount is
paid by the Issuing Lender under any Letter of Credit (or such later time or
date as provided in any reimbursement agreement entered in connection with an
Existing Northern Letter of Credit) (each such date, an "Honor Date"), in an
amount equal to the amount so paid by the Issuing Lender.  In the event the
Company fails to reimburse the Issuing Lender for the full amount of any drawing
under any Letter of Credit by 10:00 a.m., Chicago time, on the Honor Date (or
such later time or date as provided in any reimbursement agreement entered in
connection with an Existing Northern Letter of Credit), the Issuing Lender will
promptly notify the Agent and the Agent will promptly notify each Bank thereof
and the Company shall be deemed to have requested Alternate Base Rate Loan(s) be
made by the Banks to be disbursed on the Honor Date under such Letter of Credit,
subject to the amount of the unutilized portion of the Commitment and subject to
the conditions set forth in Section 7.  Any notice given by the Issuing Lender
or the Agent pursuant to this

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999



subsection 3.3(b) may be oral if immediately confirmed in writing (including by
facsimile); provided that the lack of such an immediate confirmation shall not
affect the conclusiveness or binding effect of such notice.

          (c)  Each Bank shall upon any notice pursuant to subsection 3.3(b)
make available to the Agent for the account of the Issuing Lender an amount in
Dollars and in immediately available funds equal to its Pro Rata Share of the
amount of the drawing, whereupon the participating Banks shall (subject to
subsection 3.3(d)) each be deemed to have made a Loan consisting of an Alternate
Base Rate Loan to the Company in that amount.  If any Bank so notified fails to
make available to the Agent for the account of the Issuing Lender the amount of
such Bank's Pro Rata Share of the amount of the drawing by no later than 12:00
noon, Chicago time, on the Honor Date, then interest shall accrue on such Bank's
obligation to make such payment, from the Honor Date to the date such Bank makes
such payment, at a rate per annum equal to the Federal Funds Rate in effect from
time to time during such period.  The Agent will promptly give notice of the
occurrence of the Honor Date, but failure of the Agent to give any such notice
on the Honor Date or in sufficient time to enable any Bank to effect such

payment on such date shall not relieve such Bank from its obligations under this
Section 3.3(c).

          (d)  With respect to any unreimbursed drawing that is not converted
into Loans consisting of Alternate Base Rate Loans to the Company in whole or in
part, because of the Company's failure to satisfy the conditions set forth in
Section 7.2 or for any other reason, the Company shall be deemed to have
incurred from the Issuing Lender an L/C Borrowing in the amount of such drawing,
which L/C Borrowing shall be due and payable on demand (together with interest)
and shall bear interest at a rate per annum equal to the Alternate Base Rate
plus 2% per annum, and each Bank's payment to the Issuing Bank pursuant to
subsection 3.3(c) shall be deemed payment in respect of its participation in
such L/C Borrowing and shall constitute an L/C Advance from such Bank in
satisfaction of its participation obligation under this Section 3.3

          (e)  Each Bank's obligation in accordance with this Agreement to make
the Loans or L/C Advances, as contemplated by this Section 3.3, as a result of a
drawing under a Letter of Credit, shall be absolute and unconditional and
without recourse to the Issuing Lender and shall not be affected by any
circumstance, including (i) any set-off, counterclaim, recoupment, defense or
other right which such Bank may have against the Issuing Lender, the Company or
any other Person for any reason whatsoever; (ii) the occurrence or continuance
of a Default or an Event of Default or (iii) any other circumstance, happening
or event whatsoever, whether or not similar to any of the foregoing; provided,
however, that each Bank's obligation to make Loans under this Section 3.3 is
subject to the conditions set forth in Section 7.2.

     3.4. Repayment of Participation.  (a) Upon (and only upon) receipt by the
Agent for the account of the Issuing Lender of immediately available

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


funds from the Company (i) in reimbursement of any payment made by the Issuing
Lender under the Letter of Credit with respect to which any Bank has paid the
Agent for the account of the Issuing Lender for such Bank's participation in the
Letter of Credit pursuant to Section 3.3(c) or (ii) in payment of interest
thereon, the Agent will pay to each Bank, in the same funds as those received by
the Agent for the account of the Issuing Lender, the amount of such Bank's Pro
Rata Share of such funds, and the Issuing Lender shall receive the amount of the
Pro Rata Share of such funds of any Bank that did not so pay the Agent for the
account of the Issuing Lender.

          (b)  If the Agent or the Issuing Lender is required at any time to
return to the Company, or to a trustee, receiver, liquidator, custodian, or any
official in any Insolvency Proceeding, any portion of the payments made by the
Company to the Agent for the account of the Issuing Lender pursuant to
subsection 3.4 in reimbursement of a payment made under the Letter of Credit or
interest or fee thereon, each Bank shall, on demand of the Agent, forthwith
return to the Agent or the Issuing Lender the amount of its Pro Rata Share of
any amounts so returned by the Agent or the Issuing Lender plus interest thereon
from the date such demand is made to the date such amounts are returned by such
Bank to the Agent or the Issuing Lender, at a rate per annum equal to the
Federal Funds Rate in effect from time to time.

     3.5. Role of the Issuing Bank.   (a) Each Bank and the Company agree that,
in paying any drawing under a Letter of Credit, the Issuing Lender shall not
have any responsibility to obtain any document (other than any drafts,
certificates or other documents expressly required by the Letter of Credit) or
to ascertain or inquire as to the validity or accuracy of any such document or
the authority of the Person executing or delivering any such document.

          (b)  Neither the Agent nor the Issuing Lender or their respective
officers, directors, employees or agents, nor any of the respective
correspondents, participants or assignees of the Issuing Lender shall be liable

to any Bank for:  (i) any action taken or omitted in connection herewith at the
request or with the approval of the Banks (including the Majority Banks, as
applicable); (ii) any action taken or omitted in the absence of gross negligence
or willful misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any L/C Related Document.

          (c)  The Company hereby assumes all risks of the acts or omissions of
any beneficiary or transferee with respect to its use of any Letter of Credit;
provided, however, that this assumption is not intended to, and shall not,
preclude the Company's pursuing such rights and remedies as it may have against
the beneficiary or transferee at law or under any other agreement.  Neither the
Agent nor the Issuing Lender or their respective officers, directors, employees
or agents, nor any of the respective correspondents, participants or assignees
of the Issuing Lender, shall be liable or responsible for any of the matters
described in clauses (a) through (g) of Section 3.6; provided, however, anything
in such clauses to the contrary

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


notwithstanding, that the Company may have a claim against the Issuing Lender,
and the Issuing Lender may be liable to the Company, to the extent, but only to
the extent, of any direct, as opposed to consequential or exemplary, damages
suffered by the Company which the Company proves were caused by the Issuing
Lender's willful misconduct or gross negligence or the Issuing Lender's willful
failure to pay under any Letter of Credit after the presentation to it by the
beneficiary of a sight draft and certificate(s) strictly complying with the
terms and conditions of a Letter of Credit.  In furtherance and not in
limitation of the foregoing:  (i) the Issuing Lender may accept documents that
appear on their face to be in order, without responsibility for further
investigation, regardless of any notice or information to the contrary; and (ii)
the Issuing Lender shall not be responsible for the validity or sufficiency of
any instrument transferring or assigning or purporting to transfer or assign a
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in
whole or in part, which may prove to be invalid or ineffective for any reason.

     3.6. Obligations Absolute.   The obligations of the Company under this
Agreement and any L/C Related Document to reimburse the Issuing Lender for a
drawing under a Letter of Credit, and to repay any L/C Borrowing and any drawing
under a Letter of Credit converted into Loans, shall be unconditional and
irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement and each such other L/C Related Document under all circumstances,
including the following:

          (a)  any lack of validity or enforceability of this Agreement or any
L/C Related Document;

          (b)  any change in the time, manner or place of payment of, or in any
other term of, all or any of the obligations of the Company in respect of any
Letter of Credit or any other amendment or waiver of or any consent to departure
from all or any of the L/C Related Documents;

          (c)  the existence of any claim, set-off, defense or other right that
the Company may have at any time against any beneficiary or any transferee of
any Letter of Credit (or any Person for whom any such beneficiary or any such
transferee may be acting), the Issuing Lender or any other Person, whether in
connection with this Agreement, the transactions contemplated hereby or by the
L/C Related Documents or any unrelated transaction;

          (d)  any draft, demand, certificate or other document presented under
any Letter of Credit proving to be forged, fraudulent, invalid or insufficient
in any respect or any statement therein being untrue or inaccurate in any
respect; or any loss or delay in the transmission or otherwise of any document
required in order to make a drawing under any Letter of Credit;

          (e)  any payment by the Issuing Lender under any Letter of Credit
against presentation of a draft, certificate or other document that does not

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


strictly comply with the terms of any Letter of Credit; or any payment made by
the Issuing Lender under any Letter of Credit to any Person purporting to be a
trustee in bankruptcy, debtor-in-possession, assignee for the benefit of
creditors, liquidator, receiver or other representative of or successor to any
beneficiary or any transferee of any Letter of Credit, including any arising in
connection with any Insolvency Proceeding;

          (f)  any exchange, release or non-perfection of any collateral, or any
release or amendment or waiver of or consent to departure from any other
guarantee, for all or any of the obligations of the Company in respect of any
Letter of Credit; or

          (g)  any other circumstance or happening whatsoever, whether or not
similar to any of the foregoing, including any other circumstance that might
otherwise constitute a defense available to, or a discharge of, the Company or a
guarantor.

     3.7. Cash Collateral Pledge.   Upon (a) the request of the Agent, (i) if
the Issuing Lender has honored any full or partial drawing request on any Letter
of Credit and such drawing has resulted in an L/C Borrowing hereunder, or (ii)
if, as of the Termination Date or upon an Event of Default which is continuing,
any Letters of Credit may for any reason remain outstanding and partially or
wholly undrawn, or (b) the occurrence of the circumstances described in
subsection 4.2(c) requiring the Company to Cash Collateralize Letters of Credit,
then, the Company shall immediately Cash Collateralize the L/C Obligations in an
amount equal to such L/C obligations.  The Company hereby grants the Agent, for
the benefit of the Agent, the Issuing Lender and the Banks, a security interest
in all cash and deposit account balances from time to time pledged and delivered
to the Agent, on behalf of the Banks, as security for the L/C Obligations.  Cash
collateral shall be maintained in blocked, non-interest bearing deposit accounts
at The Northern Trust Company.

     3.8. Letter of Credit Fees.   (a) The Company shall pay to the Agent for
the account of each of the Banks a letter of credit fee with respect to each
Letter of Credit equal to, in the case of standby letters of credit, .75% and,
in the case of trade letters of credit, the percentage from time to time
communicated to the Company by the Agent times the average daily maximum amount
available to be drawn on such Letter of Credit, computed on a quarterly basis in
arrears on the last Business Day of each calendar quarter upon each Letter of
Credit outstanding for that quarter as calculated by the Agent.  Such letter of
credit fees shall be due and payable quarterly in arrears on the Quarterly Dates
during which Letters of Credit are outstanding, commencing on the first such
Quarterly Date to occur after the issuance date, through the Termination Date
(or such later date upon which the outstanding Letters of Credit shall expire),
with the final payment to be made on the Termination Date (or such later
expiration date).

          (b)  (Reserved.)



    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


          (c)  The Company shall pay to the Issuing Lender from time to time on
demand the normal issuance, presentation, amendment, evergreen, drawing and
other processing fees, and other standard costs and charges, of the Issuing
Lender relating to letters of credit as from time to time in effect.

     3.9. Uniform Customs and Practice.   The Uniform Customs and Practice for
Documentary Credits as published by the International Chamber of Commerce most
recently at the time of issuance of any Letter of Credit shall (unless otherwise
expressly provided in the Letters of Credit) apply to the Letters of Credit.

     Section 4.     Payments of Principal and Interest.

     4.1. Repayment of Loans.   The Company unconditionally promises to pay to
the Agent for the account of each Bank the principal of such Bank's Loans on the
Termination Date.

     4.2  Prepayments of Loans.

          (a)  The Company shall have no right to prepay any principal amount of
any Alternate Base Rate Loans, Fed Funds Loans or Eurodollar Loans other than as
provided in subsection (b) below.

          (b)  The Company may, upon the giving of such notice as is specified
in Section 5.5 hereof, and if such notice is given the Company shall, prepay the
outstanding principal amounts of the Alternate Base Rate Loans, Fed Funds Loans
or Eurodollar Loans in whole or ratably (in accordance with the outstanding
principal amounts of Loans of such type then held by the Banks) in part,
together with accrued interest to the date of such prepayment on the principal
amount prepaid; provided, however, (i) partial prepayment shall be in an
aggregate principal amount not less than that specified in Section 5.4 and (ii)
Eurodollar Loans prepaid on a day other than the last day of an Interest Period
therefor shall be subject to Section 6.5.

          (c)  If on any date the amount of L/C Obligations exceeds the L/C
Commitment or an Event of Default occurs and is continuing, the Company shall
Cash Collateralize on such date the outstanding Letters of Credit in an amount
equal to the excess of the maximum amount then available to be drawn under the
Letters of Credit over the L/C Commitment.  Subject to Section 6.5, if on any
date after giving effect to any Cash Collateralization made on such date
pursuant to the preceding sentence, the amount of all Loans then outstanding
plus the amount of all L/C Obligations exceeds the Commitments less all L/C
Obligations, the Company shall immediately, and without notice or demand, prepay
the outstanding principal amount of the Loans and L/C Advances by an amount
equal to the applicable excess.

     4.3. Interest.

          (a)  The Company promises to pay to the Agent for the account of each
Bank interest on the unpaid principal amount of each Loan made by such

the date such Loan shall be paid in full, (i) while such Loan is an Alternate
Base Rate Loan, at a rate per annum equal to the Alternate Base Rate (as in
effect from time to time); (ii) while such Loan is a Eurodollar Loan, for each
Interest Period relating thereto, at a rate per annum equal to the LIBOR Rate
for such Loan for such Interest Period plus 50 basis points per annum; and (ii)
while such Loan is a Fed Funds Loan, at a rate per annum equal to the Fed Funds
Rate (as in effect from time to time) plus 75 basis points per annum.

          (b)  Notwithstanding the foregoing, the Company will pay to the Agent
for the account of each Bank interest at the Post-Default Rate on any principal
of any Loan made by such Bank, and (to the fullest extent permitted by law) on
any interest, any L/C Obligation or other amount payable by the Company
hereunder, under the Note held by such Bank or any L/C Related Documents which
shall not be paid in full when due (whether at stated maturity, by acceleration
or otherwise), for each day during the period from and including the due date
thereof to but excluding the date the same is paid in full.

          (c)  Accrued interest shall be payable (i) in the case of an Alternate
Base Rate Loan or Fed Funds Loan, quarterly on the Quarterly Dates, (ii) in the
case of a Eurodollar Loan, on the last day of each Interest Period therefor and
(iii) in the case of any Alternate Base Rate Loan, Fed Funds Loan or Eurodollar
Loan, upon the payment or prepayment thereof or the Conversion of such Loan to a
Loan of another type (but only on the principal amount so paid, prepaid or
Converted), except that interest payable at the Post-Default Rate shall be
payable from time to time on demand and interest on any Eurodollar Loan that is
Converted into an Alternate Base Rate Loan or Fed Funds Loan pursuant to Section
6.4 hereof shall be payable on the date of Conversion (but only to the extent so
Converted).

          (d)  Promptly after the determination of any interest rate provided
for herein or any change therein, the Agent shall give notice thereof to the
Banks and the Company.

     Section 5.     Payments; Pro Rata Treatment; Computations; Etc..

     5.1. Payments.

          (a)  Except to the extent otherwise provided herein, all payments of
principal, interest, fees and other amounts to be made by the Company under this

immediately available funds, without deduction, set-off or counterclaim, to the
Agent at such account as it may specify, not later than 1:00 p.m., Chicago time,
on the date on which such payment shall become due.  The failure of the Company
to make any such payment by such time shall not constitute a Default hereunder,
provided that such payment is received by the Agent in immediately available
funds by 4:00 p.m., Chicago time, on such due date, but any such payment after
1:00 p.m., Chicago time, on such due date

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999



shall be deemed to have been made on the next Business Day for the purpose of
calculating interest on amounts outstanding on the Loans or L/C Obligations.

          (b)  The Agent may (but shall not be obligated to) debit the amount of
any payment which is required to be made by the Company under this Agreement,
any Note, any L/C Related Document or any other document delivered in connection
herewith to any ordinary deposit account of the Company with the Agent on or
after the due date of such payment.

          (c)  Each payment received by the Agent under this Agreement, any Note
or any L/C Related Document for the account of a Bank shall be paid promptly to
such Bank, in immediately available funds, for the account of such Bank's
Applicable Lending Office for the Loan or L/C Obligation in respect of which
such payment is made.

     5.2. Pro Rata Treatment.

          Except to the extent otherwise provided herein:  (a) each Borrowing
from the Banks under Section 2.1 hereof shall be made from the Banks, each
payment of non-use fees under Section 2.4(a) hereof shall be made for the
account of the Banks, and each termination or reduction of the amount of the
Commitments under Section 2.3 hereof shall be applied to the Commitments of the
Banks, pro rata according to the amount of such Commitments; (b) the making,
Conversion and Continuation of Loans of a particular type (other than
Conversions provided for by Section 6.4 hereof) shall be made pro rata among the
Banks according to the amount of the Commitments, and the then current Interest
Period for each Loan of such type shall be coterminous; (c) each payment or
prepayment of principal of Loans by the Company shall be made for the account of
the Banks pro rata in accordance with the respective unpaid principal amounts of
the Loans of the relevant type held by the Banks; and (d) each payment of

interest on Loans by the Company shall be made for the account of the Banks pro
rata in accordance with the amounts of interest due and payable to the
respective Banks with respect to Loans of the relevant type.

     5.3. Computations.   Interest on Eurodollar Loans, Alternate Base Rate
Loans, Fed Funds Loans, non-use fees and any other fees shall be computed on the
basis of a year of 360 days for the actual number of days elapsed (including the
first day but excluding the last day) occurring in the period for which such
interest or fees are payable.  Each determination by the Agent of an interest
rate hereunder shall be conclusive and binding for all purposes, absent manifest
error.

     5.4. Minimum Amounts.   Except for Conversions or prepayments made pursuant
to Section 6.4 hereof, each Borrowing, Conversion and prepayment (other than
prepayment in full) of principal of Loans shall be in an amount at least equal
to $500,000 or increments of $50,000 in excess thereof.  Anything in this
Agreement to the contrary notwithstanding, the aggregate principal amount of
Eurodollar Loans having the same Interest Period shall be

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999

at least equal to $500,000 and, if any Eurodollar Loans would otherwise be in a
lesser principal amount for any period, such Loans shall be Alternate Base Rate
Loans during such period.

     5.5. Certain Notices.

          (a)  Notices by the Company to the Agent of terminations or reductions
of Commitments, of Borrowings, Conversions, Continuations and prepayments of
Loans, of the type of Loans and of the duration of Interest Periods shall be

               or Conversions into,

               Borrowing or repayment of,
               Conversions into, Continuations
               as, or duration of Interest
               Period for, Eurodollar Loans                3


          (b)  Each such notice of termination or reduction shall specify the
amount of the Commitments to be terminated or reduced.  Each such notice of
Borrowing (which shall be in substantially the form of Exhibit B hereto),
Conversion or Continuation (which shall be in substantially the form of Exhibit

Continued or prepaid and the amount (subject to Section 5.4 hereof) and type of

Loans to which such Interest Period is to relate.  The Agent shall promptly
notify the Banks of the contents of each such notice.

          (c)  In the event that the Company fails to select the type of Loan,
or the duration of any Interest Period for any Eurodollar Loan within the time
period and otherwise as provided in this Section 5.5, such Loan (if outstanding
as a Eurodollar Loan) will be automatically Converted into an Alternate Base
Rate Loan on the last day of the then current Interest Period

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999

for such Loan or (if outstanding as an Alternate Base Rate Loan or Fed Funds
Loan) will remain as such type of Loan, or (if not then outstanding) will be
made as, an Alternate Base Rate Loan.

     5.6. Non-Receipt of Funds by the Agent.   Unless the Agent shall have been
notified by a Bank or the Company (the "Payor") prior to the time by which the
Payor is scheduled to make a payment hereunder or any L/C Related Document to
the Agent (a "Required Payment"), which notice shall be effective upon receipt,
that the Payor does not intend to make the Required Payment to the Agent, the
Agent may assume that the Required Payment has been made and may in reliance
upon such assumption (but shall not be required to) make the amount thereof
available to the intended recipient(s) on such date and, except as otherwise
expressly provided herein, if the Payor has not in fact made the Required
Payment to the Agent, the recipient(s) of such payment shall, on demand, repay
to the Agent the amount so made available together with interest thereon in
respect of each day during the period commencing on the date such amount was so
made available by the Agent until the date the Agent recovers such amount at a
rate per annum equal to (a) in the case of the Company, the Alternate Base Rate
for such period or (b) in the case of a Bank, the Fed Funds Rate for such
period; and if such recipient(s) shall fail promptly to make such payment, the
Agent shall be entitled to recover such amount, on demand, from the Payor,
together with interest as aforesaid at (c) in the case of the Company, the
Alternate Base Rate, or (d) in the case of a Bank, the Fed Funds Rate.

     5.7. Set-off and Sharing of Payments, Etc..

          (a)  The Company agrees that in addition to any right of set-off,
banker's lien or counterclaim a Bank may otherwise have, each Bank shall be
entitled to offset balances and other claims of the Company at any of such
Bank's or its Affiliate's offices, in Dollars or in any other currency, against
any amount payable to such Bank hereunder, any L/C Related Document or under any
other document delivered in connection herewith or therewith which is not paid
when due (regardless of whether such balances and other claims are then due).

          (b)  If any Bank shall obtain payment of any principal of or interest
on any Loan or any L/C Obligation through the exercise of any right of set-off,
banker's lien or counterclaim or similar right or otherwise and, as a result of
such payment, such Bank shall have received a greater percentage of the
principal or interest then due hereunder or any L/C Obligation by the Company to
such Bank than the percentage received by any other Banks, it shall promptly
purchase from such other Banks participations in the Loans made by such other
Banks or subparticipations in the L/C Obligations of such other Banks in such
amounts, and make such other adjustments from time to time as shall be
equitable, to the end that all the Banks shall share the benefit of such excess
payment pro rata in accordance with the unpaid principal and/or interest on the
Loans and L/C Obligations held by each of the Banks.  To such end all the Banks
shall make appropriate adjustments among themselves (by the resale of
participations or

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999

subparticipations sold or otherwise) if such payment is rescinded or must
otherwise be restored.

          (c)  The Company agrees that any Bank so purchasing a participation or
subparticipation may exercise all rights of set-off, banker's lien, counterclaim

or similar rights it may otherwise have with respect to such participation or
subparticipation as fully as if such Bank were a direct holder of Loans or L/C
Obligations in the amount of such participation.

          (d)  Nothing contained herein shall require any Bank to exercise any
such right or shall affect the right of any Bank to exercise, and retain the
benefits of exercising, any such right with respect to any other Indebtedness or
obligation of the Company.

     Section 6.     Yield, Capital Maintenance and Taxes Provisions.

     6.1. Additional Costs.

          (a)  The Company shall pay directly to each Bank from time to time
such amounts as such Bank may determine to be necessary to compensate it for any
costs which such Bank determines are attributable to its making or maintaining
of any Eurodollar Loans or participating in any Letter of Credit or its
obligation to make any Eurodollar Loans hereunder or to participate in any
Letter of Credit, or any reduction in any amount receivable by such Bank
hereunder in respect of any of such Loans or such obligation or in the case of
the Issuing Lender, any increase in the cost to the Issuing Lender of agreeing
to issue, issuing or maintaining any Letter of Credit or agreeing to make or
making, funding or maintaining any unpaid drawing under any Letter of Credit
(such increases in costs and reductions in amounts receivable being herein
called "Additional Costs"), resulting from any Regulatory Change which:

               (i)  changes the basis of taxation of any amounts
          payable to such Bank or the Issuing Lender under this
          Agreement or its Note in respect of any of such Loans or
          under any L/C Related Document in respect of its L/C
          Obligations (other than taxes on the overall net income of
          such Bank or the Issuing Lender or its Applicable Lending
          Office imposed by the jurisdiction in which the Issuing
          Lender or such Bank has its principal office or such
          Applicable Lending Office);

               (ii) imposes or modifies any reserve, special deposit
          or similar requirements (other than the Reserve Requirement
          utilized in the determination of the LIBOR Rate for such
          Loan) relating to any extensions of credit (including
          extensions under this Agreement and the Notes) or other
          assets of, or any deposits with or other liabilities of,
          such Bank or the Issuing Lender or any Commitment of such
          Bank or the Issuing Lender; or

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


          (iii)     imposes any other condition affecting this Agreement,
     its Note (or any of such extensions of credit or liabilities), any L/C
     Related Document or Commitment.

     (b)  Without limiting the effect of the provisions of subsection 6.1(a)
hereof, the obligation of any Bank to make or Continue, or to Convert Alternate
Base Rate Loans or Fed Funds Loans into Eurodollar Loans hereunder shall be
suspended upon notice to the Company (with a copy to the Agent) until any
Regulatory Change ceases to be in effect (in which case the provisions of
Section 6.4 hereof shall be applicable),  in the event that, by reason of such
Regulatory Change, such Bank either (i) incurs Additional Costs based on or
measured by the excess above a specified level of the amount of a category of
deposits or other liabilities of such Bank which includes deposits by reference
to which the interest rate on Eurodollar Loans is determined or (ii) becomes
subject to restrictions on the amount of such a category of liabilities or
assets which it may hold.

     (c)  Without limiting the effect of the foregoing provisions of this
Section 6.1 (but without duplication), if any Bank or the Issuing Lender
determines that compliance with any change in any law or regulation or any
guideline or request from any central bank or other governmental authority
(whether or not having the force of law) affects or would affect the amount of
capital required or expected to be maintained by such Bank or the Issuing Lender
or any Person controlling such Bank or the Issuing Lender and that the amount of
such capital is increased by or based upon the existence of such Bank's
Commitment to lend hereunder or issue or participate in Letters of Credit and
other commitments of this type or any Loan or L/C Obligation, then, upon demand
by such Bank or the Issuing Lender (with a copy of such demand to the Agent),
the Company shall immediately pay to the Agent for the account of such Bank,
from time to time as specified by such Bank or the Issuing Lender, additional
amounts sufficient to compensate such Bank or the Issuing Lender or such Person
in the light of such circumstances, to the extent that such Bank or the Issuing
Lender determines such increase in capital to be allocable to the existence of
such Bank's Commitment to lend, issue or participate in Letters of Credit or
Loans or L/C Obligations hereunder.

     (d)  Each Bank will notify the Company of any event occurring after the
date of this Agreement that will entitle such Bank to compensation under
subsections (a) or (c) of this Section 6.1 as promptly as practicable.  Each
Bank will furnish to the Company a certificate setting forth the basis and
amount of each request by such Bank for compensation under subsections (a) or
(c) of this Section 6.1, which certificate shall be conclusive and binding on
the Company in the absence of manifest error.  Determinations and allocations by
any Bank for purposes of this Section 6.1 of the effect of any Regulatory
Change, law, regulation, guideline or request of any central bank or other
monetary authority shall be presumptively correct and binding on the Company
absent manifest error.



    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


     (e)  If the Company shall be required to make any payment or reimbursement
or to compensate any Bank under this Section 6.1, so long as no Default has
occurred and is continuing, the Company shall be free at any time within 180
days after the receipt of the certificate of the affected Bank, (i) to terminate
the affected Bank's Commitment and the affected Bank's entitlement to the fees
accruing after such termination and to prepay the Loans and PEDFA Loans of such
Bank in full together with accrued and unpaid interest on the amount thereof and
all other amounts payable hereunder and Cash Collateralize such Bank's Pro Rata
Share of the L/C Obligations, (ii) to prepay the affected portion of any Loan in
full, together with accrued and unpaid interest on the amount thereof and pay
all other amounts payable hereunder through the date of such prepayment or (iii)
to replace any such Bank with another bank reasonably acceptable to the Agent.
Upon any exercise of the rights described in clause (i), (ii) or (iii), above,
the company shall pay such affected Bank all amounts payable pursuant to Section
6.5 with respect to the cost of funds and subsection (a) or (c) of this Section
6.1 in order to compensate such affected Bank for Additional Costs or increases
in capital with respect to the period prior to termination, prepayment or
replacement, as the case may be.

     6.2. Limitation on Types of Loans.   Anything herein to the contrary
notwithstanding, if, on or prior to the determination of any LIBOR Base Rate for
any Interest Period:

          (a)  the Agent determines (which determination shall be conclusive)
that quotations of interest rates for the relevant deposits referred to in the
definition of "LIBOR Base Rate" are not being provided in the relevant amounts
or for the relevant maturities for purposes of determining rates of interest for
Eurodollar Loans as provided herein; or

          (b)  the Majority Banks determine (which determination shall be
conclusive) and notify the Agent that the relevant rates of interest referred to
in the definition of "LIBOR Base Rate" upon the basis of which the rate of
interest for Eurodollar Loans for such Interest Period is to be determined are
not likely adequately to cover the cost to such Banks of making or maintaining
such type of Loans for such Interest Period;

then the Agent shall give the Company and each Bank prompt notice thereof, and
so long as such condition remains in effect, the Banks shall be under no
obligation to make or Continue Eurodollar Loans or to Convert Alternate Base
Rate Loans or Fed Funds Loans into Eurodollar Loans and the Company shall, on
the last day(s) of the then current Interest Period(s) for the outstanding
Eurodollar Loans, either prepay such Loans or Convert such Loans into Alternate
Base Rate Loans in accordance with Section 2.8 hereof.

     6.3. Illegality.   Notwithstanding any other provision of this Agreement,
in the event that it becomes unlawful for any Bank or its Applicable Lending
Office to honor its obligation to make or maintain Eurodollar Loans hereunder,
then such Bank shall promptly notify the Company thereof (with a copy to the
Agent) and such Bank's obligation to make or

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


Continue, or to Convert Alternate Base Rate Loans or Fed Funds Loans into
Eurodollar Loans shall be suspended until such time as such Bank may again make
and maintain Eurodollar Loans (in which case the provisions of Section 6.4
hereof shall be applicable).

     6.4. Treatment of Affected Loans.

          (a)  If the obligation of any Bank to make or Continue, or to Convert
Alternate Base Rate Loans or Fed Funds Loans into Eurodollar Loans is suspended
pursuant to Sections 6.1, 6.2 or 6.3 hereof, such Bank's Eurodollar Loans shall
be automatically Converted into Alternate Base Rate Loans on the last day(s) of
the then current Interest Period(s) for the Eurodollar Loans (or, in the case of
a Conversion required by Section 6.3 hereof, on such earlier date as such Bank
may specify to the Company with a copy to the Agent) and, unless and until such
Bank gives notice as provided below that the circumstances specified in Section
6.1, 6.2 or 6.3 hereof which gave rise to such Conversion no longer exist:

               (i)  to the extent that such Bank's Eurodollar Loans
          have been so Converted, all payments and prepayments of
          principal which would otherwise be applied to such Bank's
          Eurodollar Loans shall be applied instead to its Alternate
          Base Rate Loans; and

               (ii) all Loans which would otherwise be made or
          Continued by such Bank as Eurodollar Loans shall be made or
          Continued instead as Alternate Base Rate Loans and all Loans
          of such Bank which would otherwise be Converted into
          Eurodollar Loans shall remain as Alternate Base Rate Loans.

          (b)  If such Bank gives notice to the Company (with a copy to the
Agent) that the circumstances specified in Section 6.1, 6.2 or 6.3 hereof which
gave rise to the Conversion of such Bank's Eurodollar Loans pursuant to this
Section 6.4 no longer exist (which such Bank agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Loans are outstanding,
such Bank's Alternate Base Rate Loans shall be automatically Converted, on the
first day(s) of the next succeeding Interest Period(s) for such outstanding
Eurodollar Loans to the extent necessary so that, after giving effect thereto,
all Eurodollar Loans are held pro rata (as to principal amounts, types and
Interest Periods) in accordance with the Commitments.

     6.5. Compensation.

          (a)  The Company shall pay to the Agent for the account of each Bank,
upon the immediately following Quarterly Date after the request of such Bank
through the Agent, such amount or amounts as shall be sufficient to compensate
it for any loss, cost or expense which such Bank determines are attributable to
(i) any payment, prepayment or Conversion of a Eurodollar

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


Loan made by such Bank for any reason (including, without limitation, the
acceleration of the Loans pursuant to Section 10 hereof or a prepayment pursuant
to Section 4.2 hereof) on a date other than the last day of the Interest Period
for such Loan; or (ii) any failure by the Company for any reason (including,
without limitation, the failure of any of the conditions precedent specified in
Section 7 hereof to be satisfied) to borrow a Eurodollar Loan from such Bank on
the date for such Borrowing specified in the relevant notice of Borrowing given

foreclosure.

          (d)  The Company shall immediately advise the Agent in writing of:

discovery of any occurrence or condition on the Premises or any real property

deliver to the Agent any documentation or records as the Agent may reasonably
request in connection with all such notices, inquiries, and communications, and
shall advise the Agent promptly in writing of any subsequent developments.

          (e)  The Agent shall give written notice to the Company of any legal,
administrative or other action against any Bank Party which might give rise to a

option and the Company's expense, may be required to defend against such action
with counsel satisfactory to the Agent and such Bank and, with the Agent's sole
consent and approval, to settle and compromise any such action.  However, such
Bank may elect to be represented by separate counsel, at such Bank's expense,

Bank may elect to join and participate in any settlements, remedial actions,
legal proceedings or other actions included in connection with any claims under
this Section 9.19.

          (f)  If the Agent reasonably believes that retention of counsel or
consultants for advice or other representation is desirable (i) in any

and the indemnities described herein, or (ii) to enforce the Company's
obligations hereunder, then all of the attorneys' and consultant fees (including
without limitation, time charges of attorneys who may be employees of the Agent)
reasonably incurred by the Agent arising from such services and all related
expenses and court costs shall be payable on demand by the Company to the Agent.

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


     Section 11.    The Agent.

     11.11.    Appointment, Powers and Immunities.  Each Bank hereby irrevocably
appoints and authorizes the Agent to act as its agent hereunder and under the
L/C Related Documents with such powers as are specifically delegated to the
Agent by the terms of this Agreement and the L/C Related Documents, together
with such other powers as are reasonably incidental thereto.  The Agent:  (a)
shall not have any duties or responsibilities except those expressly set forth
in this Agreement and the L/C Related Documents, and shall not by reason of this

Agreement and the L/C Related Documents be a trustee for any Bank; (b) shall not
be responsible to the Banks for any recitals, statements, representations or
warranties contained in this Agreement, the L/C Related Documents or in any
certificate or other documents referred to or provided for in, or received by
any of them under, this Agreement, the Notes or the L/C Related Documents or for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement, any Note, any L/C Related Document or any other document
referred to or provided for herein or therein or for any failure by the Company
or any other Person to perform any of its obligations hereunder or thereunder;
(c) shall not be required to initiate or conduct any litigation or collection
proceedings hereunder or under any L/C Related Documents; and (d) shall not be
responsible for any action taken or omitted to be taken by it hereunder, any L/C
Related Documents or under any other document or instrument referred to or
provided for herein or therein or in connection herewith or therewith, except
for its own gross negligence or willful misconduct.  The Agent may employ agents
and attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it in good faith.
The Agent may deem and treat the payee of any Note as the holder thereof for all
purposes hereof unless and until a written notice of the assignment or transfer
thereof shall have been consented to in accordance with Section 12.6.

     The Issuing Lender shall act on behalf of Banks with respect to any Letters
of Credit issued by it and the documents associated therewith until such time
and except for so long as the Agent may agree at the request of the Majority
Banks to act for such Issuing Lender with respect thereto; provided, however,
that such Issuing Lender shall have all of the benefits and immunities (x)
provided to the Agent in this Section 11 with respect to any acts taken or
omissions suffered by such Issuing Lender in connection with Letters of Credit
issued by it or proposed to be issued by it and the application and agreements
for letters of credit pertaining to the Letters of Credit as fully as if the
term "Agent", as used in this Section 11, included such Issuing Lender with
respect to such acts or omissions, and (y) as additionally provided in this
Agreement with respect to the Issuing Lender.

     11.2.     Reliance by Agent.  The Agent shall be entitled to rely upon any
certification, notice or other communication (including any thereof by telephone
or telecopy) believed by it to be genuine and correct and to have been signed or
sent by or on behalf of the proper Person or Persons, and upon advice and
statements of legal counsel, independent accountants and other

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


experts selected by the Agent.  As to any matters not expressly provided for by
this Agreement or the L/C Related Documents, the Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder in accordance
with instructions signed by the Majority Banks or all the Banks if required in
accordance with Section 12.4, and such instructions of the Majority Banks or all
the Banks, as applicable, and any action taken or failure to act pursuant
thereto shall be binding on all of the Banks.

     11.3.     Defaults.  The Agent shall not be deemed to have knowledge or
notice of the occurrence of a Default unless the Agent has received notice from
a Bank or the Company specifying such Default and stating that such notice is a
"Notice of Default."  In the event that the Agent receives such a notice of the
occurrence of a Default, the Agent shall give prompt notice thereof to the
Banks.  The Agent shall (subject to Section 11.1 and Section 11.7 hereof) take
such action with respect to such Default as shall be directed by the Majority
Banks, provided that, unless and until the Agent shall have received such
directions, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default as it shall deem
advisable in the best interest of the Banks.

     11.4.     Rights as a Bank.  With respect to its Commitment, the Loans made
by it and the Letters of Credit in which it participates, The Northern Trust

Company in its capacity as a Bank hereunder shall have the same rights and
powers hereunder as any other Bank and may exercise the same as though it were
not acting as the Agent, and the term "Bank" or "Banks" shall, unless the
context otherwise indicates, include The Northern Trust Company in its
individual capacity.  The Northern Trust Company and its respective Affiliates
may (without having to account therefor to any Bank) accept deposits from, lend
money to and generally engage in any kind of banking, trust or other business
with the Company (and any of its Affiliates) as if it were not acting as the
Agent, and The Northern Trust Company and its respective Affiliates may accept
fees and other consideration from the Company for services in connection with
this Agreement, the L/C Related Documents or otherwise without having to account
for the same to the Banks.

     11.5.     Indemnification.  The Banks agree to indemnify the Agent (to the
extent not reimbursed under Section 12.3 hereof, but without limiting the
obligations of the Company under said Section 12.3), ratably in accordance with
the aggregate principal amount of the Loans made by the Banks (or, if no Loans
are at the time outstanding, ratably in accordance with their respective
Commitments), for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement, the
Notes, the L/C Related Documents or any other documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
(including, without limitation, the costs and expenses which the Company is
obligated to pay under Section 12.3 hereof but excluding, unless a Default has
occurred and is continuing,

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


normal administrative costs and expenses incident to the performance of its
agency duties hereunder) or the enforcement of any of the terms hereof or of any
such other documents, provided that no Bank shall be liable for any of the
foregoing to the extent they arise from the gross negligence or willful
misconduct of the Agent.

     11.6.     Non-Reliance on Agent and other Banks.  Each Bank agrees that it
has, independently and without reliance on the Agent or any other Bank, and
based on such documents and information as it has deemed appropriate, made its
own credit analysis of the Company and its Subsidiaries and decision to enter
into this Agreement and any L/C Related Documents and that it will,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own analysis and decisions in taking or not taking action
under this Agreement and any L/C Related Documents.  The Agent shall not be
required to keep itself informed as to the performance or observance by the
Company of this Agreement, any L/C Related Document or any other document
referred to or provided for herein or to inspect the properties or books of the
Company or any of its Subsidiaries.  Except for notices, reports and other
documents and information expressly required to be furnished to the Banks by the
Agent hereunder, the Agent shall not have any duty or responsibility to provide
any Bank with any credit or other information concerning the affairs, financial
condition or business of the Company or any of its Subsidiaries (or any of their
Affiliates) which may come into the possession of the Agent or any of its
Affiliates.

     11.7.     Failure to Act.  Except for action expressly required of the
Agent hereunder, the Agent shall in all cases be fully justified in failing or
refusing to act hereunder unless it shall receive further assurances to its
satisfaction from the Banks of their indemnification obligations under Section
11.5 hereof against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action.

     11.8.     Resignation of Agent.  Subject to the appointment and acceptance

of a successor Agent as provided below, the Agent may resign at any time by
giving thirty (30) days' notice thereof to the Banks and the Company.  Upon any
such resignation, the Majority Banks shall have the right to appoint a successor
to the resigning Agent from amongst the Banks, subject to the approval of the
Company which shall not be withheld unreasonably.  If no successor to such Agent
shall have been so appointed by the Majority Banks and shall have accepted such
appointment within thirty (30) days after the Agent's giving of notice of
resignation, then the resigning Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a bank which has an office in Chicago, Illinois
and having capital and retained earnings of at least $100,000,000.  Upon the
acceptance of any appointment as an Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning Agent, and the resigning
Agent shall be discharged from its duties and obligations hereunder.  After the
Agent's resignation hereunder, the provisions of this Section 11 shall continue
in effect for its benefit in

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


respect of any actions taken or omitted to be taken by it while it was acting as
the Agent.

     Section 12.    Miscellaneous.

     12.1.     Waiver.  No failure on the part of the Agent or any Bank to
exercise, no delay in exercising, and no course of dealing with respect to, any
right, power or privilege under this Agreement, any Note or the L/C Related
Documents shall operate as a waiver thereof, nor shall any single or partial
exercise thereof preclude any other or further exercise thereof or the exercise
of any other right, power or privilege.  The remedies provided herein are
cumulative and not exclusive of any remedies provided by law.

     12.2.     Notices.  All notices and other communications provided for

its notice address or telecopy number specified in Schedule 1 hereto or, as to
any party, at such other address as shall be designated by such party in a

postage prepaid, in each case given or addressed as aforesaid; provided, that
notices to the Agent shall be effective only upon actual receipt.

     12.3.     Expenses, Etc.   The Company agrees to pay or reimburse each of
the Banks (in the case of clauses (b) and (c) below) and the Agent and Issuing
Lender for:  (a) all reasonable out-of-pocket costs and expenses of the Agent
(including, without limitation, the reasonable fees and expenses of Gardner,

Agreement, the Notes, the L/C Related Documents or any other document referred
to herein or therein.

     12.4.     Amendments, Etc.  Except as otherwise expressly provided in this
Agreement, any provision of this Agreement or L/C Related Document may be

                 and Northern Trust Company as of May 20, 1999

Majority Banks or all the Banks, as the case may be, affect the rights or duties
of such Issuing Lender under this Agreement or any L/C Related Document relating
to any Letter of Credit issued or to be issued by it.

     12.5.     Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
permitted assigns.

     12.6.     Assignments and Participations.

          (a)  The Company may not assign its rights or obligations hereunder,
the L/C Related Documents or under the Notes without the prior consent of all of
the Banks and the Agent.

          (b)  Any Bank may, in the ordinary course of its business and in
accordance with applicable law, at any time sell to one or more banks or other
entities ("Participants") participating or subparticipating interests in any
Loan or L/C Obligation owing to such Bank, the Note held by such Bank, the
Commitment of such Bank or any other interest of such Bank.  Each Bank shall
promptly provide notice of the identity of each Participant to the Company and
the Agent.  In the event of any such sale by a Bank of participating or
subparticipating interests to a Participant, such Bank shall remain solely
responsible to the other parties hereto for the performance of such obligations,
such Bank shall remain the holder of its Note and L/C Obligations for all
purposes hereunder, all amounts payable by the Company under this Agreement or
any L/C Obligation shall be determined as if such Bank had not sold such
participating or subparticipating interest, and the Company and the Agent shall
continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations hereunder.

          (c)  Each Bank shall retain the sole right to approve, without the
consent of any Participant, any amendment, modification or waiver of any
provision hereunder other than any amendment, modification or waiver of any
provision hereunder with respect to any Loan, Commitment or L/C Obligation in
which such Participant has an interest which forgives principal, interest or
fees or reduces the interest rate or fees payable with respect to any such Loan,
Commitment or L/C Obligation, postpones any date fixed for any

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999

regularly-scheduled payment of principal of, or interest or fees on, any such
Loan, Commitment or L/C Obligation, releases any guarantor, if any, of any such
Loan or L/C Obligation or releases any substantial portion of collateral, if
any, securing any such Loan or L/C Obligation.

          (d)  The Company agrees that each Participant shall be deemed to have
the right of setoff provided in Section 5.7 in respect of its participating or
subparticipating interest in amounts owing hereunder or under L/C Related
Documents to the same extent as if the amount of its participating or
subparticipating interest were owing directly to it as a Bank hereunder,
provided that each Bank shall retain the right of setoff provided in Section 5.7
with respect to the amount of participating or subparticipating interests sold
to each Participant.  The Banks agree to share with each Participant, and each
Participant, by exercising the right of setoff provided in Section 5.7, agrees
to share with each Bank, any amount received pursuant to the exercise of its
right of setoff, such amounts to be shared in accordance with Section 5.7 as if
each Participant were a Bank.

          (e)  Any Bank may, in the ordinary course of its business and in
accordance with applicable law, at any time assign to one or more banks or other
entities ("Purchaser") all or any part of its rights and obligations hereunder,
under its Note or in any L/C Obligation.  Such assignments shall be pursuant to
Assignment Agreements substantially in the form of Exhibit G hereto.  The
consent of the Company and the Agent shall be required prior to any assignment
becoming effective with respect to the Purchaser which is not a Bank or an
Affiliate thereof; provided, however, that if a Default has occurred and is
continuing, the consent of the Company shall not be required.  Such consent
shall not be unreasonably withheld or delayed.  Each such assignment shall be in
an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining
amount of the assigning Bank's Commitment (calculated as the date of such
assignment).

          (f)  Upon (i) the delivery to the Agent of a notice of assignment,
substantially in the form attached as Exhibit "I" to Exhibit G hereto (a "Notice
of Assignment"), together with any consents required by subsection (e) above,
and (ii) payment of a $2,500 fee to the Agent for processing such assignment,
such assignment shall become effective on the effective date specified in such
Notice of Assignment.  The Notice of Assignment shall contain a representation
by the Purchaser to the effect that none of the consideration used to make the
purchase of the Commitment, L/C Obligations and Loans under the applicable
Assignment Agreement are "plan assets" as defined under ERISA and that the
rights and interests of the Purchaser in and under this Agreement will not be
"plan assets" under ERISA.  On and after the effective date of such assignment,
such Purchaser shall for all purposes be a Bank party to this Agreement and
shall have all rights and obligations of a Bank hereunder, to the same extent as
if it were an original party hereto, and no further consent or action by the
Company, the Banks or the Agent shall be required to release the transferor Bank
with respect to the percentage of its Commitment, L/C Obligations and Loans
assigned to such Purchaser.  Upon the consummation of any assignment to a
Purchaser pursuant to this Section
12.6, the transferor Bank, the Agent and the Company shall make appropriate

    Exhibit 4a - $30,000,000 Revolving Credit Agreement among Fansteel, Inc.
                 and Northern Trust Company as of May 20, 1999


arrangements so that a replacement Note is issued to such transferor Bank and a
new Note or, as appropriate, a replacement Note, is issued to such Purchaser, in
each case in principal amounts reflecting their Commitment, as adjusted pursuant
to such assignment.

          (g)  The Company authorizes each Bank to disclose to any Participant
or Purchaser or any other Person acquiring an interest hereunder by operation of
law (each a "Transferee") and any prospective Transferee any and all information
in such Bank's possession concerning the creditworthiness of the Company and its
Subsidiaries; provided that each Transferee and prospective Transferee agrees to
be bound by Section 12.10 of this Agreement.

     12.7.     Survival.  The obligations of the Company under Sections 6.1,
6.5, 9.19 and 12.3 hereof shall survive the repayment of the Loans and L/C
Obligation and the termination of the Commitments.

     12.8.     Captions.  The table of contents and captions and section
headings appearing herein are included solely for convenience of reference and
are not intended to affect the interpretation of any provision of this
Agreement.

     12.9.     Counterparts.  This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument, and any of the parties hereto may execute this Agreement by signing
any such counterpart.

     12.10.    Confidentiality.  Each Bank and the Agent agree to use reasonable
precautions to keep confidential, in accordance with their customary procedures
for handling confidential information of this nature and in accordance with safe
and sound banking practices, any non-public information supplied to it by the
Company pursuant to this Agreement; provided that nothing herein shall limit the
disclosure of any such information (a) to the extent required by statute, rule,
regulation or judicial process, (b) to counsel for or other professional
advisors to any of the Banks or the Agent, (c) to bank examiners, auditors or
accountants, (d) to any other Bank, (e) in connection with any litigation to
which any one or more of the Agent or Banks is a party or (f) to any Affiliate
of the Agent or any Bank.

     12.11.    Governing Law.  THIS AGREEMENT, AND THE NOTES SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAW OF THE STATE OF ILLINOIS.

     12.12.    Waiver of Jury Trial.  THE COMPANY, THE AGENT AND THE BANKS
HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT, THE L/C RELATED DOCUMENTS, THE NOTES OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY.
