NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

INTERIM FINANCIAL INFORMATION

     The accompanying unaudited, consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting of normal,
recurring adjustments) considered necessary for a fair presentation have been
included. Results for the interim periods are not necessarily indicative of the
results for an entire year.

NOTE 2.  LINE OF CREDIT

     During the second quarter of 1998, the Company amended its line of credit
agreement with its primary bank. The amended line of credit provides for
borrowings up to $5,000,000 at an interest rate of prime minus1/2% (8% at June
30, 1998). All other major terms and conditions remain the same.

NOTE 3.  STOCK SPLIT

     On May 15, 1998, the Company completed a three-for-two stock split. All
share and per share information has been restated to reflect this stock split.

</TABLE>

FOR THE THREE MONTHS ENDED JUNE 30, 1998 AND 1997.

     NET SALES. Net sales increased 94%, or approximately $5,076,000, to
approximately $10,484,000 for the three months ended June 30, 1998 compared with
the same period in 1997. The increase was due primarily to sales of the
Company's Posi-Track vehicle and related accessories increasing 104% over 1997.
The growth in Posi-Track sales was due to increased demand for the Company's HD
series Posi-Track which was introduced in fourth quarter 1997 and accounted for
nearly all unit volume in second quarter 1998. The HD series Posi-Track features
a maintenance-free suspension which minimizes operator maintenance on the
vehicle, as well as offering a more powerful engine and greater lifting
capabilities than the Company's original model MD-70 Posi-Track. The Company
will offer this same maintenance-free suspension under the MD-70 chassis as a
new series of Posi-Tracks, the MD series. Sales of the new MD series are
expected to start in third quarter 1998. Sales of parts, used equipment and
other items increased 35% for the three month period ended June 30, 1998
compared with the same period in 1997. This increase was primarily due to parts
sales increasing as the number of vehicles in the field continues to increase.

     In connection with the expansion of its manufacturing facility and increase
in the models in its product lines, the Company is anticipating continued growth
in its net sales in excess of 50% for the next twelve months.

     GROSS PROFIT. Gross profit for the three months ended June 30, 1998
increased to approximately $2,561,000, or 24.4% of net sales, compared with
$1,292,000, or 23.9% of net sales, in 1997. The increased gross profit was
attributable to increased sales volume in 1998. The increased gross profit
percentage was attributable to greater efficiencies in the production process
from the Company's increased production levels and additional margin obtained
from the sale of higher priced products.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses decreased from 9.8% of net sales in second quarter 1997,
to 9.0% of net sales in second quarter 1998. The increased dollar volume was due
to increased advertising costs including costs to promote the Company's HD
series Posi-Track as well as increased compensation costs as sales and
administrative personnel have been added to support expanded sales and customer
service roles. The decreased percentage of selling, general and administrative
expenses was due to the Company closely managing its costs.

     RESEARCH AND DEVELOPMENT. Research and development expenses increased from
approximately $63,000 in second quarter 1997 to approximately $105,000 in 1998.
The increase was due mainly to the development of the Company's new model
Posi-Track, the MD series, continuing improvements to the Company's existing
models and exploration of future product alternatives.

                                       6
<PAGE>
 
     In order to maintain its competitive advantage over other manufacturers of
similar products, the Company believes it will increase the level of spending on
research and development activities. It is expected the main thrust of these
activities will be directed towards extensions of the Company's current product
lines and improvements of existing products.

     INTEREST EXPENSE. Interest expense increased from approximately $93,000 for
the second quarter of 1997 to approximately $127,000 for the second quarter of
1998. The increase was due to the additional debt related to the completion of
the Company's facility expansion and the additional debt incurred in January
1998 for the acquisition of land and buildings for storage and to house research
and development activities.

     NET INCOME. Net income for the second quarter of 1998 was approximately
$927,000, compared with approximately $465,000 for the second quarter of 1997.
The increase in 1998 resulted primarily from additional gross profit on
increased sales, offset in part by increased operating costs and interest
expense.

FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997.

     NET SALES. Net sales for the six months ended June 30, 1998 increased 94%,
or approximately $9,454,000, to $19,513,000. The increase was due primarily to
the increased sales of the Company's Posi-Track vehicle, particularly the HD
series Posi-Track, which was introduced in fourth quarter 1997. Posi-Track
related sales increased 106% due to the increased demand, sales of two new
Posi-Track models in 1998 and new dealers added in the past twelve months. Sales
of parts, used equipment and other items increased approximately 37% due
primarily to an increase in the sale of parts as a greater number of machines
are in service in 1998.

     GROSS PROFIT. Gross profit increased for the six months ended June 30, 1998
to approximately $4,819,000, or 24.7% of net sales, from $2,362,000, or 23.5% of
net sales, for the six months ended June 30, 1997. The increased gross profit
was due to increased sales while the increased gross profit percentage was due
to the increased efficiencies obtained from the Company's increased production
volume and additional margin obtained from the sale of higher priced products.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses decreased from 10.1% of net sales for the six months
ended June 30, 1997 to 9.0% of net sales for the six months ended June 30, 1998.
The increased dollar amount of approximately $731,000 was due to increased sales
and marketing costs and increased costs for administrative personnel hired to
support increased sales volumes. The decreased percentage of selling, general
and administrative expenses was due to the Company closely managing its costs.

     RESEARCH AND DEVELOPMENT. Research and development expenses increased from
approximately $108,000 in 1997 to approximately $204,000 in 1998. The increase
was due mainly to the development of the Company's new model Posi-Track, the MD
series, in 1998, continuing improvements to the Company's existing models and
exploration of additional models.

     INTEREST EXPENSE. Interest expense increased from approximately $186,000
for the six months ended June 30, 1997 to approximately $256,000 for the same
period in 1998. The increase was due to the additional debt related to the
completion of the Company's facility expansion and the additional debt incurred
in January 1998 for the acquisition of land and buildings for storage and to
house research and development activities.

     NET INCOME. Net income for the six months ended June 30, 1998 increased to
approximately $1,719,000 from approximately $780,000 for 1997. The increase is
due to increased sales and gross profit, offset in part by increased operating
expenses and interest expense.

LIQUIDITY AND CAPITAL RESOURCES

     At June 30, 1998, the Company had working capital of approximately
$14,913,000 compared with working capital of approximately $11,033,000 at June
30, 1997, an increase of approximately $3,880,000. The major components of this
increase are as follows: Inventories increased approximately $6,270,000 due to
the introduction of two new Posi-Track models in 1997 and one new Posi-Track
model in 1998 along with increased sales; Accounts receivable increased
approximately $1,625,000 due to increased sales; Cash and short-term investments
decreased approximately $2,424,000 as the Company built inventory levels and
equipped its expanded manufacturing facility; Current liabilities increased
approximately $1,742,000 due to the overall increase in the Company's volume and
profitability.

                                       7
<PAGE>
 
     The Company's working capital position at June 30, 1998 increased
approximately $1,571,000 when compared with December 31, 1997. Major components
of this increase are as follows. Inventories increased approximately $2,077,000
and accounts payable increased approximately $1,286,000 due to the increase in
the Company's production levels and additional parts required to manufacture new
models. Accounts receivables increased approximately $777,000 due to increased
sales volume. Cash and short-term investments increased approximately $402,000
due to increased profitability. In addition, the current portion of long-term
liabilities increased approximately $218,000 due to the additional debt incurred
for the Company's facility expansion and the acquisition of land and buildings
for storage and to house the Company's research and development activities.

     During the second quarter of 1998, the Company amended its line of credit
agreement with its primary bank. The amended line of credit provides for
borrowings up to $5,000,000 at an interest rate of prime minus 1/2% (8% at June
30, 1998). All other major terms and conditions remain the same. The Company
believes its existing cash and investments, together with cash expected to be
provided by operations and available, unused credit lines, will satisfy the
Company's projected working capital needs and other cash requirements at least
through the end of June 1999.

     The Company has increased its number of employees by approximately 50% in
the last 12 months. In order to meet its anticipated sales levels for the next
twelve months, the Company expects it will increase its number of employees by
approximately 20% over the next twelve months. It is anticipated that nearly all
the additional employees will be in the production area. The Company believes
the local work force is sufficient to hire the additional employees.

     In order to maintain its competitive advantage over other manufacturers of
similar products, the Company believes it will increase the level of spending on
research and development activities. It is expected the main thrust of these
activities will be directed towards extensions of the Company's current product
lines and improvements of existing products.

     IMPACT OF THE YEAR 2000 ISSUE. The Year 2000 issue is the result of
computer programs being written using two digits rather than four to define the
applicable year. Some of the Company's computer programs that have
date-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. This could result in a system failure or miscalculations
causing disruptions of operations, including, among other things, a temporary
inability to process critical business transactions including recording of
sales, manufacture of products, inventory management and distribution,
preparation of invoices and collection of accounts receivables and many other
normal business activities.

     The Company has begun to identify all relevant software that may affect the
Company's operations through surveys and examinations. Based on risk assessments
that have been completed for the majority of the Company's operations, the
Company must upgrade some of its existing software to ensure that the computer
systems will properly utilize dates beyond December 31, 1999. The Company
expects to convert its business operations to new Year 2000 compatible software
by the end of 1998. The cost of these conversions is not expected to have a
material impact on the Company. However, there can be no guarantee the software
of other companies on which the Company's systems rely will be timely converted,
or that a failure to convert by another company, or a conversion that is
incompatible with the Company's systems, would not have a material adverse
effect on the Company.

     The statements set forth above under "Liquidity and Capital Resources" and
elsewhere in this Form 10-Q which are not historical facts are forward-looking
statements and involve risks and uncertainties, many of which are outside the
Company's control and, accordingly, actual results may differ materially.
Factors that might cause such a difference include, but are not limited to, lack
of market acceptance of new or existing products, inability to attract new
dealers for the Company's products, unexpected delays in obtaining raw
materials, unexpected delays in the manufacturing process, unexpected additional
expenses or operating losses or the activities of competitors. Any
forward-looking statements provided from time-to-time by the Company represent
only management's then-best current estimate of future results or trends.
