                     LINDBERG CORPORATION AND SUBSIDIARIES

                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1    Condensed Financial Statements

          The condensed consolidated financial statements included
          herein have been prepared by the company, without audit,
          pursuant to the rules and regulations of the Securities and
          Exchange Commission.  Certain information and footnote
          disclosures normally included in financial statements prepared
          in accordance with generally accepted accounting principles
          have been condensed or omitted pursuant to such rules and
          regulations, although the company believes that the
          disclosures are adequate to make the information presented not
          misleading.  It is suggested that these condensed financial
          statements be read in conjunction with the consolidated
          financial statements and the notes thereto included in the
          company's latest annual report on Form 10-K.

          Statements for the three month and nine month periods ended
          September 30, 2000 and September 30, 1999 reflect, in the
          opinion of the company, all adjustments (consisting only of
          normal recurring accruals) necessary to present fairly the
          results of these periods. Results for interim periods are not
          necessarily indicative of results for a full year.

NOTE 2    Acquisitions

          On June 2, 2000, the company acquired all of the assets of
          Thermo TerraTech Inc.'s heat treating services group ("HTSG").
          The acquired group includes the operations of Metallurgical in
          Minneapolis, Metal Treating in Milwaukee and Cal-Doran in Los
          Angeles and San Diego. The company purchased the assets
          collectively from HTSG for $17.3 million, with $15.7 million
          paid at closing and $1.6 million paid subsequent to June 30,
          2000 as a final purchase price adjustment.  On August 18, 2000
          the company acquired all of the assets of Industrial Heat
          Treating & Metallurgical Company, Inc. of Indianapolis,
          Indiana, for $1.7 million of cash and $600,000 of a note
          payable.  Cash payments made as part of each purchase were
          funded with borrowings under the company's revolving credit
          agreement.

          The preliminary allocation of the purchase price of HTSG
          included in the company's financial statements for the quarter
          is as follows:  (in thousands)

NOTE 3    Material Changes

          No material changes have occurred with respect to the
          company's contingent liabilities outlined in the company's
          1999 10-K through the date of this report.  However, the
          company did establish reserves for environmental contingencies
          of $1.0 million in connection with the acquisition of HTSG.

NOTE 4    Other

          In the first quarter of  2000, the company and a partner
          formed an ion-plasma nitriding technology company in the Los
          Angeles area named Accurate Ion Technologies, LLC ("Accurate
          Ion").  The company holds a 25% interest in Accurate Ion and
          accounts for this investment under the equity method of
          accounting.  As such, the company records its share of the
          income of Accurate Ion in the period earned.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION:

At September 30, 2000, the company's total debt was $58.9 million, an
increase of $15.5 million from $43.4 million outstanding at December 31,
1999.  The company's total debt to capitalization ratio was 48% at the
end of the third quarter of 2000 as compared to 42% at the end of 1999.

The principal reasons for the increase in the level of debt during the
first nine months of 2000 were the acquisition of the heat treating
services group of Thermo TerraTech Inc. ("HTSG") in June 2000 for $17.3
million and the acquisition of Industrial Heat Treating & Metallurgical
Company, Inc. ("IHT") in August 2000 for $2.3 million.  The purchase
price for each acquisition was funded with additional borrowings under
the company's revolving credit agreement and, in the case of IHT, the
issuance of $600,000 of a note payable to the sellers.  Partially
offsetting the increase in debt from these acquisitions was the receipt
of $2.2 million of cash in April 2000 from the sale of land and a
building which the company owned and had been leasing to the purchaser
of one of the company's previously discontinued Precision Products
businesses.  Cash generated through operations for the nine-month period
also offset the effect of the acquisitions to a degree.

The company maintains, with two banks, a revolving credit facility with
a total borrowing capacity of $70 million.  The maturity date of the
agreement relating to the facility is December 2002.  At September 30,
2000, the company had $18 million of available capacity under that
revolving credit facility.

Capital expenditures for the first nine months of 2000 were $6.3
million, a decrease from $8.3 million in the corresponding period of
1999.  The spending in the first nine months of 2000 related primarily
to the acquisition of additional furnaces and equipment at the company's
facilities.

On July 28, 2000, the Board of Directors declared a cash dividend of
$.08 on each share of the company's common stock, payable on
September 1, 2000.  The total cash dividends paid on the latter date were
$453,000.  This compared to a cash dividend payout of $.08 per share of
common stock, or $473,000, in the same period of 1999.

The company believes that its borrowing capacity and funds generated
through operations will be sufficient to meet currently foreseen capital
investment and working capital needs in support of existing businesses
for the balance of 2000 and in the longer term.

OF RESULTS OF OPERATIONS:

Quarter ended September 30, 2000 and 1999

Net sales for the quarter ended September 30, 2000 were $33.4 million,
an increase of $4.4 million, or 15%, from $29.0 million in the
corresponding period of 1999.  Excluding the acquisitions of HTSG and
IHT, which contributed $4.8 million in sales to the third quarter 2000
results, the company's sales decreased by 1% versus the third quarter of
1999.  The decline in sales, after considering the effect of the
acquisitions, resulted primarily from a lower level of sales in the
month of July 2000 as compared to the same month last year.

Gross profit for the third quarter of 2000 was $8.3 million, up
$400,000, or 5%, from $7.9 million in the third quarter of 1999.  The
gross profit improved in the quarter as a result of contributions from
the acquisitions during the quarter.  The company's gross margin in the
third quarter of 2000 was 25.0%, compared to 27.1% in the same period of
1999.  A significant factor in the decrease in the gross margin was
higher energy costs - in particular, increased natural gas costs
nationally and electricity costs in Southern California.  It is
estimated that about half of the decline in gross margin was related to
the effect of higher energy costs.  The company has implemented
adjustments in its pricing in an effort to mitigate to the extent
possible the effect of the higher energy costs in the future.  However,
there can be no assurances that the effects of the higher energy costs
will be fully offset.

Selling and administrative expenses for the third quarter of 2000 were
$5.0 million, up from $4.5 million in the same period of 1999.
Excluding $500,000 of expenses related to HTSG and IHT in the 2000
period, selling and administrative expenses were $4.5 million -
essentially level with the third quarter of 1999.  Selling and
administrative expenses as a percentage of sales were 15.1% for the
third quarter of 2000, down from 15.6% in the same period of 1999.

Interest expense net of interest income in the third quarter of 2000 was
$971,000, compared to $546,000 in the third quarter of 1999.  The
increase resulted largely from higher borrowing levels due to the
acquisitions of HTSG and IHT.  Higher interest rates to a lesser degree
contributed to the increased expense for the period.

During the third quarter of 2000, the company recorded investment
earnings of $79,000 relating to two companies in which it holds a
minority interest, Thixomat, Inc. ("Thixomat") and Accurate Ion
Technologies, LLC ("Accurate Ion").  In the third quarter of 1999, the
company recorded investment earnings of $44,000 related to Thixomat.

Reflecting the above, net earnings in the third quarter of 2000 were
$1.4 million, down from $1.7 million for the corresponding period of
1999.  Diluted earnings per share in the third quarter of 2000 were $.25
as compared to $.28 in the third quarter of 1999.  The weighted number
of shares and equivalents for the third quarter of 2000, compared to the
same quarter of 1999, were lower as a result of the purchase by the
company of 264,000 shares of common stock for the treasury in December
1999.

Nine months ended September 30, 2000 and 1999

Net sales for the nine months ended September 30, 2000 were $95.0
million, up $2.3 million, or 2%, from $92.7 million in the corresponding
period of 1999.  Excluding the effect of the acquisitions of HTSG and
IHT in the comparison, sales for the 2000 period declined 4% from the
first nine months of 1999.  This decline in net sales was largely
reflective of reduced business levels, in comparison to the year-ago
period, at company facilities serving customers in the commercial
aerospace industry in the first six months of 2000.

<PAGE>                              -10-

Gross profit for the first nine months of 2000 was $25.1 million, down
$2.0 million, or 7%, from $27.1 million for the first nine months of
1999.  The gross profit decline in the 2000 period was largely the
result of the decrease in net sales, excluding the effect of
acquisitions, during the period.  Also adversely affecting the gross
profit in the 2000 period was higher energy costs, which began to move
significantly upward during the second quarter of the year.  The
company's gross margin in the first nine months of 2000 was 26.4%
compared to 29.2% in the corresponding period of 1999.  In addition to
the negative effect of higher energy costs on gross margin in 2000, the
decline was reflective of the adverse effect of the lower sales in
relation to the company's relatively fixed cost structure.

Selling and administrative expenses for the first nine months of 2000
were $14.8 million as compared to $14.3 million for the same period of
1999.  Excluding expenses relating to HTSG and IHT, selling and
administrative expenses in the 2000 period were $14.2 million, 1% below
the figure for 1999.  As a percent of sales, selling and administrative
expenses were 15.6% for the first nine months of 2000 - essentially
level with the prior year.

Interest expense net of interest income in the first nine months of 2000
was $2.3 million, compared to $1.6 million in the first nine months of
1999.  The increase in net expense in 2000 related primarily to
additional borrowings due to the acquisitions of HTSG and IHT, and to a
lesser degree to higher interest rates in the 2000 period.

During the first nine months of 2000, the company recorded income of
$242,000 from its investments in Thixomat and Accurate Ion.  In the same
period of 1999, $74,000 in investment earnings related solely to
Thixomat were recorded.

Reflecting the above, net earnings in the first nine months of 2000 were
$4.9 million, down from $6.6 million for the corresponding period of
1999.  Diluted earnings per share in the first nine months of 2000 were
$.86 as compared to $1.10 in the same period of 1999.
