MANAGEMENT DISCUSSION AND ANALYSIS
----------------------------------

COMPARISON OF SECOND QUARTER 1999 TO SECOND QUARTER 1998

Second quarter 1999 includes the results of operations for Holophane, S.A. de
C.V., ("HSA") acquired in June 1998. The Company acquired all of the stock of
HSA, a licensee located in Mexico City, from ID Mexico, a closely held company.
HSA has manufactured and marketed certain of the Company's lighting products
since 1962.

Worldwide net sales for the second quarter of 1999 were $58.7 million, up $7.3
million, or 14% from second quarter 1998. Excluding HSA, sales increased
approximately 12% in the quarter. Second quarter sales in the United States
increased 15% compared to 1998 due to strong growth in outdoor and fluorescent
products. European sales in local currency were up 10% compared to second
quarter 1998, reflecting strong business conditions in Germany. Canadian sales
were down 27% in local currency compared to 1998 due to generally weaker
business conditions.

Gross margin percent was 39.1% in 1999 compared to 38.4% in 1998. Operating
income was $7.6 million, up from $7.0 million. The increase in operating income
is due to higher volume, partially offset by higher selling, administrative and
other expenses. Total operating expenses in the quarter were $15.4 million, up
from $12.8 million in 1998.

Net interest expense decreased by less than $0.1 million in 1999 due to lower
average interest rates.

The tax rate in 1998 was 34.7%, down from 37.7% in 1998. The reduction in the
effective income tax rate is primarily the result of tax credits associated with
a dividend received from the Company's European subsidiary.

Net income and diluted earnings per share were $4.8 million and $0.44,
respectively, compared with $4.2 million and $0.37 in 1998. Basic earnings per
share were $0.45 compared to $0.38.

On June 21, 1999, National Service Industries ("NSI") and the Company announced
they had signed a definitive agreement under which NSI would acquire Holophane
for $38.50 per share in cash. The transaction was approved unanimously by the
boards of directors of both companies and is expected to be completed in the
fourth quarter of NSI's fourth quarter.

COMPARISON OF FIRST SIX MONTHS 1999 TO FIRST SIX MONTHS 1998

Net sales for the 1999 period were $111.5 million, up $12.8 million or 13% from
the same period in 1998. Sales in the United States increased approximately 12%
compared to 1998 due to strong growth in outdoor and fluorescent products. In
local currencies, European sales have increased 9% compared to the prior year
period due primarily to strong business conditions in Germany and Canadian sales
have decreased 12% compared to 1998 due to generally weaker business conditions.

<PAGE>   11
Gross margin percent was 39.0% in 1999 compared to 38.6% in 1998. Operating
income in 1999 was $13.7 million compared to $12.4 million in 1998. The increase
in operating income is due to higher volume, partially offset by higher
operating expenses. Operating expenses for the year are $29.8 million, up from
$25.7 million in 1998.

Net interest expense decreased by $0.1 million in 1999 compared to 1998. The
decrease in interest expense was due to lower average interest rates.

The tax rate in 1999 was 35.3%, down from 37.2% in 1998. The reduction in the
effective income tax rate is primarily the result of tax credits associated with
a dividend received from the Company's European subsidiary.

Net income and diluted earnings per share were $8.6 million and $0.78,
respectively, compared with $7.4 million and $0.66 in 1998. Basic earnings per
share were $0.81 compared to $0.68.

CAPITAL RESOURCES AND LIQUIDITY

The Company has an unsecured $30 million three-year revolving credit commitment
through National City Bank. The commitment expires on April 1, 2001. At June 30,
1999, the Company had $10.5 million available under this arrangement. Cash on
hand, funds generated from operations and amounts available under the credit
agreement are expected to adequately fulfill Holophane's anticipated
requirements for the remainder of 1999.

Working capital was $35.2 million as of June 30, 1999, up $1.5 million from
year-end 1998 due primarily to seasonal volume related increases in receivables
and inventory offset by higher payables and compensation accruals.

YEAR 2000 ISSUE

Background
----------

Holophane initiated the formal process of conducting a systematic audit of all
business systems, facilities, products and computing hardware for the Year 2000
in February 1997. The company employed a multi-step approach in connection with
its Year 2000 Project, each step designed to evaluate specific critical business
systems within the company as well as communicating with external service
providers and other suppliers to understand their plan to remedy their own Year
2000 issues.

Based on the results of our investigations, Holophane date sensitive business
systems will be modified and tested as required to handle date information
before, during and after midnight December 31, 1999, including data input,
output and calculations comparing dates and portions of dates.

                                        9
<PAGE>   12
Project
-------

The company conducted an evaluation of the impact of Year 2000 on information
systems and developed an evaluation matrix from which Year 2000 compliance could
be monitored. Financial systems used by the company are vendor software products
that are certified by the vendor as Year 2000 ready releases. Nonetheless, the
company will test the financial systems during 1999. An outside consulting firm
conducted a separate study of in-house manufacturing systems and, as of the date
of this filing, all in-house manufacturing systems have been modified and
successfully tested for Year 2000. A separate evaluation of manufacturing
equipment is underway and will be completed in 1999. All network systems were
either migrated or upgraded to match Year 2000 ready local area network (LAN)
systems. Current installed LAN server equipment is Year 2000 ready. Personal
computers, phone systems, timekeeping and security systems are being evaluated
and will be Year 2000 ready prior to December 31, 1999.

None of the company's other information technology projects have been delayed
due to the implementation of the Year 2000 project.

Costs
-----

Holophane estimates that the total cumulative cost of the project will be
approximately $200,000 which includes both internal and external personnel costs
related to modifying the systems. All costs related to the project are being
expensed as incurred. The costs of the project and the expected completion dates
are based on management's best estimate.

Risks
-----

At this time, the company believes its most reasonable worst case scenario is
that key suppliers or service providers who have not resolved their own Year
2000 issue may cause a disruption of service to the company's critical business
processes, which in turn could affect the company's ability to manufacture and
deliver product. The company has initiated formal inquiries with suppliers with
which it has active contracts to determine the extent to which the company is
vulnerable to those third parties' failure to remediate their own Year 2000
issue. The company cannot predict the outcome of other companies' remediation
efforts.

Contingency Plans
-----------------

The company has an ongoing business interruption contingency plan to address
internal and external issues specific to the Year 2000 problem, to the extent
practicable. Depending on the status of third party Year 2000 readiness, these
plans include changing suppliers, advanced purchases of critical inventory and
extending production scheduling.

Forward Looking Statements

                                       10
<PAGE>   13
preceding "Year 2000 Issue" discussion contains various forward-looking
statements which represent the company's belief or expectations regarding future
events. All forward-looking statements involve a number of risks and
uncertainties that could cause the actual results to differ materially from the
projected results. Factors that may cause these differences include, but are not
limited to, the availability of information technology resources; the ability to
identify and remediate all date sensitive computer code in affected systems or
equipment; the actions of third parties with respect to Year 2000 problems and
other risks detailed in the Company's Securities Exchange Act of 1934 filing.
