                      For Three Months Ended March 31, 2000

Sales and Earnings

Sales for the quarter ended March 31, 2000 were $11,529,341 compared to
$8,910,832 for the same period a year ago. This increase of $2,618,509 is
attributed to increased demand for the Company's lighting products, improved
production throughput of the Company's variable message signs, and an increase
in bus window systems and glass compared to the same period a year ago.

During the first quarter of 2000, the Company recorded a net loss of $115,562 on
sales of $11,529,341. For the same period of the prior year, the Company
reported a net profit of $21,699 on sales of $8,910,832 The Company's
electronics and lighting operations, showed improved operating results over the
same period a year ago. However, this improvement was more than offset by higher
losses incurred at TransGlass, Inc. the producer of bus windows systems. It is
anticipated that as TransGlass "grows" into their new facility and cost
structure, coupled with increase labor efficiencies, operating profits will
start to be realized in the third quarter of 2000.

Inventories

Inventory valuation is based upon the lower of cost or market. At March 31,
2000, consolidated inventories were $14,268,991 compared to $11,831,454 a year
ago. This increase of $2,437,537 is to accommodate increased sales compared to a
year ago, and is concentrated in raw materials. It also reflects approximately
$350,000 of finished goods for a customer who was on credit hold at 3/31/2000.

Interest

Interest expense amounted to approximately $310,000 and $184,000 for the first
quarter of 2000 and 1999, respectively. This increase of $126,000 was the result
of higher debt levels in 2000, plus increased interest costs tied to the bank's
prime rate.

Financial Condition

Current financial resources coupled with anticipated funds from operations are
expected to meet funding requirements for the remainder of the year, based upon
present needs.
