Effective  August 30, 1998,  Thomas  Industries Inc.  ("Thomas") and The Genlyte
Group  ("Genlyte")  formed Genlyte Thomas Group LLC ("GTG"),  combining  Thomas'
lighting business with Genlyte (the "Joint Venture"). Genlyte has a 68% interest
in GTG, and Thomas holds a 32% interest, which is accounted for using the equity
method of  accounting.  Thomas changed its method of accounting for the lighting
business  contributed to GTG to the equity method effective January 1, 1998, the
beginning of Thomas' prior fiscal year, restating results for the quarters ended
March 31 and June 30, 1998.  The  restatement of results using the equity method
for the 1998 quarterly periods prior to consummation of the Joint Venture had no
effect on net income or common shareholders' equity but did reduce its revenues,
costs, assets, and liabilities, and changed certain components of cash flow.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


Note A - Basis of Presentation
------------------------------

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial  reporting and with the instructions to Form 10-Q and Article 10-01 of
Regulation  S-X.  Accordingly,  they  do not  include  all the  information  and
footnotes  required by generally  accepted  accounting  principles  for complete
financial statements.

The results of operations  for the nine-month  period ended  September 30, 1999,
are not necessarily  indicative of the results that may be expected for the year
ending  December  31,  1999.  In the  opinion  of  management,  all  adjustments
considered  necessary for a fair  presentation  have been included.  For further
information,  refer  to the  consolidated  financial  statements  and  footnotes
included in the Company's Annual Report on Form 10-K for the year ended December
31, 1998.

Effective  August 30, 1998,  Thomas and Genlyte  formed GTG,  combining  Thomas'
lighting  business with  Genlyte.  Genlyte has a 68% interest in GTG, and Thomas
holds a 32%  interest,  which is  accounted  for  using  the  equity  method  of
accounting.  Thomas changed its method of accounting  for the lighting  business
contributed to GTG to the equity method effective January 1, 1998, the beginning
of Thomas' prior fiscal year,  restating results for the quarters ended March 31
and June 30, 1998.  The  restatement  of results using the equity method for the
1998 quarterly  periods prior to consummation of the Joint Venture had no effect
on net income or common shareholders' equity but did reduce its revenues, costs,
assets, and liabilities, and changed certain components of cash flow.
(See Note D.)

Note B - Contingencies
----------------------

In the normal  course of business,  the Company is a party to legal  proceedings
and claims. When costs can be reasonably estimated,  appropriate liabilities for
such matters are recorded.  While  management  currently  believes the amount of
ultimate  liability,  if any, with respect to these actions will not  materially
affect the  financial  position,  results of  operations,  or  liquidity  of the
Company,  the  ultimate  outcome  of  any  litigation  is  uncertain.   Were  an
unfavorable outcome to occur, the impact could be material to the Company.

Item 2.  Management's  Discussion  and  Analysis  of  Financial Condition  and
         Results of Operations

Results of Operations
---------------------

Net sales during the third quarter ended  September 30, 1999, were $39.9 million
compared  to $43.1  million  for the third  quarter  1998.  Since the  Company's
Lighting business was contributed to GTG effective August 30, 1998, the 1998 net
sales reflect the  application of the equity  method,  retroactive to January 1,
1998,  and  therefore  include  only net sales for the  Compressor & Vacuum Pump
operations.  The North American  operations and the European operations declined
from the third  quarter 1998 sales  levels.  Several of our major OEM  customers
cancelled or pushed out orders due to slack  demand in their end markets,  which
contributed to this decline. Net sales for the nine-month period ended September
30, 1999, were $133.6 million compared to $137.7 million for the prior year. For
the nine-month period, the North American operations showed a slight improvement
over the prior-year period,  while the European  operations declined compared to
the prior year.

Operating  income for the third  quarter  ended  September  30, 1999,  was $11.4
million  compared to $12.8 million for the third quarter 1998.  For the quarter,
both the North American and European  Compressor & Vacuum Pump operations showed
decreases  compared to the 1998 third quarter.  This resulted primarily from the
reduced sales levels. Our Lighting results reflect the application of the equity
method  retroactive to January 1, 1998.  Therefore,  the prior-year  results for
January through August included pretax operating income from the Thomas Lighting
operations.  After the GTG joint  venture  was  formed on August 30,  1998,  all
subsequent  Lighting  results also include our 32 percent share of foreign taxes
and interest  expense.  This makes  meaningful  comparisons  to the prior year's
quarter and year-to-date Lighting results very difficult. Our third quarter 1999
net equity earnings from GTG were $6.4 million, compared to $6.9 million for the
prior-year  quarter.  As  mentioned  above,  Thomas'  share of  GTG's  quarterly
earnings was lower than the prior year's  Lighting  results due to the manner in
which  foreign  taxes and interest  expense are  accounted  for under the equity
method of  accounting.  After  adjusting for these items,  the  earnings,  which
included two months of Thomas'  former  operations and one month of GTG results,
would be up over prior years' levels. Operating income for the nine-month period
ended September 30, 1999, was $34.6 million compared to $34.9 for the nine-month
period in 1998. The North American operations  reflected an improvement over the
prior-year period,  while the European operations showed a decrease for the 1998
nine-month  period.  An increase in the GTG earnings for the  nine-month  period
helped to offset some of the reduction in the Compressor & Vacuum Pump results.

Net income for the 1999 third  quarter of $6.7  million  was 4.3% lower than the
$7.1  million for the  comparable  1998 period.  This  reduction  was  primarily
related to the lower sales levels.  Net income for the  nine-month  period ended
September  30,  1999,  was  $19.9  million  compared  to $19.2  million  for the
nine-month  period in 1998.  The first nine  months of 1999 were the highest for
any previous first nine-month period in the Company's history.

Interest  expense for the 1999 third  quarter was $1.1  million,  or 29.1% lower
than the prior-year amount of $1.6 million. The decrease was attributed


<PAGE>


Item 2.  Management's Discussion and Analysis --Continued

primarily to a significant reduction in short-term debt, which was higher in the
third  quarter  of 1998  due to the  funding  of  working  capital  needs of the
Lighting business. Also, long-term debt of $7.7 million was paid down on January
31, 1999, which reduced interest  expense over the prior-year  amount.  Interest
income was $.3 million  higher in the 1999 third  quarter  versus the 1998 third
quarter.  The  nine-month  period for 1999  reflected a $.9 million  increase in
interest income over the prior year.  These increases are the result of improved
cash flows and  interest  received  from GTG on a  $22,287,000  note  payable to
Thomas.

Included in Other Long-Term  Assets at September 30, 1999,is  $22,287,000  which
represents  the debt  equalization  note payable to Thomas by GTG related to the
formation of the Joint  Venture.  Interest on the principal  amount  outstanding
under the note accrues at a variable  rate based on LIBOR plus the Offshore Rate
Margin and is payable on a quarterly  basis. The principal amount of the note is
due on  August  29,  2003,  and may be  prepaid  in whole or in part at any time
without premium or penalty.

Working  capital of $31.1 million at September 30, 1999, is $1.3 million  higher
than the amount at December 31, 1998. Accounts receivable at September 30, 1999,
have  increased by 7.1% since December 31, 1998, due to seasonality in our sales
volume. The number of days sales in receivables at September 30, 1999,  compared
to December 31, 1998, has decreased to 48.3 days from 49.1.  Inventory  turnover
at September  30, 1999, of 5.1 times per year  improved  significantly  from the
December 31, 1998, level of 4.5.

Certain loan agreements of the Company include  restrictions on working capital,
operating  leases,  tangible net worth,  and the payment of cash  dividends  and
stock distributions. Under the most restrictive of these arrangements,  retained
earnings of $64.1 million are not restricted at September 30, 1999.

As of September 30, 1999, the Company had available  credit of $7.9 million with
banks under short-term borrowing  arrangements which was unused. Due to improved
cash flows,  the Company  dissolved  the $30 million  revolving  line of credit.
Anticipated funds from operations,  along with available  short-term credit, are
expected to be sufficient to meet cash  requirements in the year ahead.  Cash in
excess of  operating  requirements  will  continue to be invested in  investment
grade, short-term securities.

Year 2000 Issue
---------------

In the third quarter of 1996, the Company recognized the need to ensure that its
operations  would not be adversely  affected by Year 2000 computer  hardware and
software  failures.  Certain systems would fail,  unless  modified,  to properly
handle  date-sensitive  calculations  for dates that crossed the  century.  Such
systems  could fail because the systems use only two digits  rather than four to
define a specific  year.  These  failures  would pose known  risks to the future
integrity of the Company's financial reports and to virtually all aspects of the
Company's   operations,   including  the  Company's  ability  to  process  sales
transactions,  fulfill customer orders,  and receive and manage  inventories and
other assets.



<PAGE>

Item 2.  Management's Discussion and Analysis --Continued

Plans for achieving internal Year 2000 compliance were finalized during 1996 and
included  a  goal  to be  complete  by  the  end  of  the  third  quarter  1998.
Accordingly,  the Company  completed  a high level  analysis of the scope of the
issues to be addressed,  created a team of IT resources,  and contracted  with a
major software  consulting firm to assist in the Year 2000 remediation  efforts.
The discovery phase of the problems and the plan for remediation  were completed
in 1997. Remediation and testing were completed on most systems during 1998. The
objective  of these  efforts is to achieve Year 2000  compliance  with a minimal
effect on customer  service or other  disruption  to, or loss of  integrity  in,
business or financial  operations.  At this date,  sources of potential  failure
have been  identified,  and we believe  that they have all been  remediated.  We
believe that all critical software is now compliant.

The  Company  has  performed  an  assessment  of  its  material  non-Information
Technology  systems such as CAD  systems,  PBX  systems,  Environmental  Control
systems,  Elevator Control systems,  and numeric control devices and, based upon
this assessment, believes that these systems are Year 2000 compliant.

The Company has communicated with its major suppliers and customers to determine
their Year 2000  compliant  status and to identify  any issues or problems  with
respect  to their  Year 2000  preparedness  that might  adversely  affect  their
companies.  The Company is continuing its efforts to obtain such assurances from
all critical  suppliers.  Failure of these third  parties  could have a material
impact  on  operations   and/or  the  Company's  ability  to  deliver  products.
Contingency  planning is being  established and will be implemented in an effort
to minimize any impact from Year 2000 related failures.

Through September 30, 1999,  approximately $2.4 million in costs, which includes
Compressors  &  Vacuum  Pumps  and  Lighting  costs,  has been  incurred  in the
Company's efforts to achieve Year 2000 compliant systems.  These costs have been
incurred  over the 1996-1999  time frame and have not been,  nor are expected to
be, a material  incremental  cost having an impact on the Company's  operations,
financial condition, or liquidity and include the costs for both its Vacuum Pump
& Compressor  business and the Company's former Lighting  business.  These costs
consist  primarily  of  outsourced   consulting  and  remediation  efforts.  Any
remaining costs for the Company are expected to be less than $25,000. There have
been no major system projects  cancelled or delayed as a result of the Company's
Year 2000 costs.

The above expectations are subject to uncertainties. For example, if the Company
is  unsuccessful in identifying or fixing all Year 2000 problems in our critical
operations,  or if we are affected by the  inability  of our  suppliers or major
customers to continue operations due to such problems, our results of operations
or financial condition could be materially affected.

The Company has a minority  interest in GTG,  which has advised the Company that
it is  currently in the process of  identifying  and  remediating  its Year 2000
issues as well as  conducting a review to gain  reasonable  assurances  that its
business  partners are addressing  Year 2000 issues.  If GTG is  unsuccessful in
identifying or remediating all Year 2000 problems in its critical operations, or
if it is  affected by the  inability  of its  suppliers  or major  customers  to
continue  operations  due to such  problems,  this  could  have an impact on the
Company's financial results and condition.

Item 2.  Management's Discussion and Analysis --Continued

New European Currency
---------------------

Eleven  European  countries  (The European  Monetary  Union) have  implemented a
single  currency  zone as of January  1,  1999.  The new  currency  (Euro)  will
eventually replace the existing currencies of the participating countries. It is
expected that this transition from the various currencies to the Euro will occur
over a three-year period.  Since the Company's  European  Operations may have to
accommodate dual currencies during this period, modifications to our third-party
software at our European  locations may be necessary.  A team has been formed to
monitor EMU developments,  evaluate the requirements, develop and execute action
plans and work with our third party software providers to address this issue.

While management  currently believes the Company will be able to accommodate any
required changes in its operations  without  significant  costs, there can be no
assurance that the Company,  its customers,  suppliers and service  providers or
government  agencies  will all meet the Euro currency  requirements  in a timely
manner.  Such  failure to complete  the  necessary  work on a timely basis could
result in material financial risk.


Item 3.  Quantitative and Qualitative Disclosures about Market Risk

The  Company's  long-term  debt bears  interest at fixed rates;  therefore,  the
Company's  results of operations would only be affected by interest rate changes
to the extent that variable rate,  short-term notes payable are outstanding.  At
September 30, 1999, short-term notes payable are not significant.

The Company has  significant  operations  consisting of sales and  manufacturing
activities in foreign countries.  As a result,  the Company's  financial results
could be  significantly  affected by factors such as changes in foreign currency
exchange rates or weak economic  conditions in the foreign  markets in which the
Company  manufactures  or  distributes  its  products.  Currency  exposures  are
concentrated  in Germany but exist to a lesser  extent in other parts of Western
Europe and Asia.
