                                   (Unaudited)

NOTE 1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Interim Financial Information

     The accompanying unaudited 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.

Reclassifications

     Certain 1998 amounts have been reclassified to conform with the
presentation in the 1999 financial statements.

NOTE 2.    SHAREHOLDERS' EQUITY

     On October 14, 1998, the Company entered into a Securities Purchase
Agreement (the Agreement) with Caterpillar Inc. The Agreement was approved by
the Company's shareholders on January 28, 1999 and subsequently closed on
January 29, 1999. Under the terms of the Agreement, Caterpillar acquired, for an
aggregate purchase price of $18,000,000, one million newly issued shares of
common stock and a warrant to purchase an additional 10,267,127 newly issued
shares of common stock at a price of $21.00 per share. The warrant is
exercisable immediately and at any time over the next ten years, subject to
partial termination in the event the Company achieves certain financial goals.
As a result of the Agreement, the board of directors was increased from eight to
ten members with the additional two members appointed by Caterpillar. In
addition, the Agreement contains other provisions which allow Caterpillar to
maintain its proportionate potential ownership and that restricts certain
situations including acquisitions, loans and the payment of dividends, without
approval of at least one of the Caterpillar designated members of the Board.

     The Company and Caterpillar have entered into a Commercial Alliance
Agreement pursuant to which Caterpillar will provide the Company with access to
its dealer network and will make various management, financial and engineering
resources available to the Company. Included in the Commercial Alliance
Agreement is a Marketing Agreement which provides, among other things, that the
Company will pay Caterpillar a commission equal to 5% of the dealer net price
for complete machines and 3% for replacement parts and Company-branded
attachments for all sales made to Caterpillar dealers. In addition, if the
Company's products are sold under the Caterpillar brand name, the Company will
pay Caterpillar a trademark license fee equal to 3% of the net sales of these
products to Caterpillar dealers. The Company and Caterpillar also entered into
other ancillary agreements for the benefit of both the Company and Caterpillar.

     Upon closing, Caterpillar owned approximately 8.8% of the Company's
outstanding common stock (assuming the exercise of all outstanding options and
warrants). Caterpillar will have the right to own up to approximately 52% of the
Company's common stock (assuming the exercise of all outstanding options and
warrants) upon exercise of the warrant.

     The warrant issued to Caterpillar provides for a potential change of
control. As a result, in accordance with the 1994 and 1996 stock option plans,
all previously issued stock options became fully vested upon the closing of the
transaction. As a result of the acceleration, the Company will reflect pro forma
compensation of approximately $4,400,000 in its calculation of pro forma net
income and pro forma net income per share for 1999, in accordance with pro forma
disclosures required by Statement of Financial Accounting Standard No. 123 -
"Accounting for Stock Based Compensation".

     In connection with the Agreement, the Company incurred expenses of
approximately $448,000, which were offset against the proceeds for the issued
shares.

NOTE 3.  CONTINGENCY

     The Year 2000 issue relates to limitations in computer systems and
applications that may prevent proper recognition of the Year 2000. The potential
effect of the Year 2000 issue on the Company and its business partners will not
be fully determinable until the year 2000 and thereafter. If Year 2000
modifications are not properly completed either by the Company or entities with
whom the Company conducts business, the Company's financial condition and
results of operations could be adversely impacted.

                             RESULTS OF OPERATIONS

Results of Operations

     The following table sets forth certain Statements of Earnings data as a
percentage of net sales:

                                                    Three Months Ended March 31,
                                                       1999             1998
                                                       ----             ----
   Net sales......................................    100.0%           100.0%
   Cost of goods sold.............................     73.6%            75.0
   Gross profit...................................     26.4%            25.0
   Selling, general and administrative expenses...     13.2%             9.0
   Operating income...............................     12.0%            15.0
   Interest expense...............................      0.8%             1.4
   Net income.....................................      7.7%             8.8

     Net Sales. For the three months ended March 31, 1999, net sales were
approximately $8,463,000, a decrease of six percent compared with the three
months ended March 31, 1998. This decrease was due to the reduced sales of
Posi-Track vehicles and related accessories due to the continued transition of
distributing the Posi-Track through a primarily independent dealer network to
the Caterpillar dealer network. As of April 23, 1999, the Company has a total of
24 Caterpillar dealers selling Posi-Tracks. Of these 24 dealers, who have 154
locations, 21 are located in the United States, which represents one-third of
all U.S. Caterpillar dealers. The Company's total dealer location count is
approximately 200, compared with approximately 100 at this time last year. Sales
of parts, used equipment and other items increased 39% for the three month
period ended March 31, 1999 as compared with 1998. This increase was due in part
to a 65% increase in the sale of parts as the number of vehicles in the field
has increased. Also, the Company recognized net sales of approximately $665,000
in the first quarter of 1999 for the final subcontract work performed on a
military contract.

     Gross Profit. Gross profit for the three months ended March 31, 1999 was
approximately $2,237,000 compared with approximately $2,258,000 in 1998.
However, the gross profit percentage increased from 25.0% in 1998 to 26.4% in
1999. The increased gross profit percentage can be attributed to a greater
number of units produced in 1999, which resulted in lower fixed costs per unit,
and also improved inventory management.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased from approximately $808,000, or 9.0% of net
sales in 1998, to approximately $1,113,000, or 13.2% of net sales in 1999. These
increases are due primarily to increased marketing costs as well as higher
compensation costs as sales and administrative personnel have been added to
support expanded sales and customer service roles. In addition, with the closing
of the Commercial Alliance Agreement with Caterpillar Inc., the Company began
paying a commission to Caterpillar for sales to Caterpillar dealers as of
January 29, 1999. This commission accounted for slightly over one-half of the
percentage increase in selling, general and administrative expenses.

     Research and Development. Research and development expenses increased from
approximately $98,000 in 1998 to approximately $108,000 in 1999. The increase is
due to the Company devoting more resources to future product alternatives.

     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 decreased from approximately $129,000
for the first quarter of 1998 to approximately $66,000 for the first quarter of
1999. The decrease was the net effect of two factors. First, the Company's
convertible debentures were exchanged for common stock in the fourth quarter of
1998, eliminating future interest expense on the debentures. Second, the Company
utilized its line of credit during the month of January, prior to the closing of
the Caterpillar transaction, to fund operations.


                                       7
<PAGE>
 
     Net Income. Net income for the first quarter of 1999 was approximately
$649,000, as compared with approximately $792,000 for the first quarter of 1998.
The decrease in 1999 resulted primarily from slightly reduced sales and
increased operating expenses, offset in part by an increased gross profit
percentage and decreased interest expense.

Liquidity and Capital Resources

     At March 31, 1999, the Company had working capital of approximately
$35,653,000 compared with working capital of approximately $17,416,000 at
December 31, 1998, an increase of approximately $18,237,000. This increase was
due to the sale of common stock and warrant to Caterpillar Inc. in January 1999
for $18 million. The Company used these proceeds primarily to pay off its line
of credit and fund current operations. During the transition to Caterpillar
dealers, the Company chose not to reduce its production levels, but instead,
increased its finished goods. This decision, along with the repurchase of
certain inventory from current and former dealers, caused inventory levels to
increase 39% compared with December 31, 1998. Accounts receivable increased as
extended terms have been offered to certain dealers. Also, approximately
$665,000 was invoiced in March 1999 for the final subcontract work performed on
a military contract.

     On October 14, 1998, the Company entered into a Securities Purchase
Agreement (the Agreement) with Caterpillar Inc. (Caterpillar). The Agreement was
approved by the Company's shareholders on January 28, 1999 and closed January
29, 1999. Under the terms of the Agreement, Caterpillar acquired, for an
aggregate purchase price of $18,000,000, one million newly issued shares of the
Company's common stock and a warrant to purchase an additional 10,267,127
newly-issued shares of the Company's common stock at a price of $21.00 per
share. Also under the terms of the Agreement, the Company's board of directors
was increased from eight to ten with the additional two members appointed as
designated by Caterpillar.

     In connection with entering into the Agreement, the Company and Caterpillar
have entered into several ancillary agreements. These agreements provide the
Company access to Caterpillar's dealer network and also make various management,
financial and engineering resources from Caterpillar available to the Company
following the closing. One of these agreements is a Marketing Agreement which
provides, among other things, that the Company will pay Caterpillar a commission
equal to 5% of the dealer net price for complete machines and 3% for replacement
parts and Company-branded attachments for all sales made to Caterpillar dealers.
Should the Company manufacture products that are sold under the Caterpillar
brand name, the Company will pay Caterpillar a trademark license fee equal to 3%
of the net sales of these products to Caterpillar dealers.

     It is the intent of the Company and Caterpillar to introduce the Company's
Posi-Track products to Caterpillar's North American dealers as soon as
practicable. With the signing and announcement of the Agreement with
Caterpillar, certain of the Company's existing, non-Caterpillar dealers have
been hesitant to place orders for the Company's products. Management believes
these dealers are uncertain of their future status as Posi-Track dealers.
Between the time of the announcement of the Caterpillar transaction and March
1999, approximately 36 dealer locations elected to no longer carry the Company's
products. These 36 locations are comprised of eleven dealers who will no longer
carry the Company's products and two dealers whose Posi-Track trade areas have
been reduced. One of those dealers whose trade area has been reduced was the
Company's largest customer for 1998. This dealer accounted for approximately 21%
of the Company's net sales in 1998. This dealer is a Caterpillar dealer and
their Posi-Track trade area was reduced as they were selling into the trade area
of approximately nine other Caterpillar dealers.

     The Company believes its sales during the first quarter of 1999 decreased
due to the factors discussed above. In addition, several Caterpillar dealers
have chosen to wait until they have received training on the Posi-Track from
factory representatives before placing significant orders. The Company is in the
process of providing this training. The Company believes the slow-down in sales
is temporary and expects the order level to increase as additional Caterpillar
dealers receive training and begin carrying the Posi-Track models. Although the
Company has been working closely with Caterpillar to introduce the Posi-Track
products to North American Caterpillar dealers as quickly as possible, the
Company may experience a decrease in its sales volume while the Company proceeds
through this transitional period with Caterpillar.

     In connection with the replacement of the Company's independent dealers
with Caterpillar dealers, the Company has made arrangements with certain dealers
to repurchase their existing inventory of Posi-Track products and transfer it to
the new Caterpillar dealers. In some instances, it has been necessary for the
Company to take possession of the inventory, rather than transferring it
directly to the new Caterpillar dealer. In these situations, the Company will be
responsible for re-marketing this inventory. The Company does not currently
anticipate a material loss from the re-marketing of this inventory.



                                       8
<PAGE>
 
     As a result of the transaction, the Company's near term revenues,
profitability and other financial results are expected to be lower than if the
transaction were not entered into. The decline is related to a number of
factors, including (i) the commission to be paid to Caterpillar for sales made
to Caterpillar dealers, (ii) transition issues affecting orders from the
preexisting non-Caterpillar affiliated dealers, and (iii) certain other costs of
implementing the Transaction and the agreements contemplated by the Commercial
Alliance Agreement. Over the longer term, however, management believes that the
Company will be able to achieve improved financial results due to the
Transaction and the Commercial Alliance Agreement.

     The Company believes its existing cash and marketable securities, 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 for at least the next twelve months.

     Impact of the Year 2000 Issue. The Company has established a team to assess
and address the possible exposures related to the Year 2000 ("Y2K") issue and is
in the initial assessment phase. The areas under investigation include business
computer systems, production equipment, vendor readiness and contingency plans.
The Company does not use internally developed computer software and is therefore
not anticipating major reprogramming efforts. The Company's primary financial
and operational system has been assessed and is certified Y2K compliant. There
are several ancillary applications that may not currently be Y2K compliant, but
the Company expects it will be able to purchase Y2K compliant versions by mid to
late-calendar 1999, the cost of which is not expected to be material. The
majority of the Company's personal computers are currently Y2K compliant. Those
computers that may not currently be Y2K compliant are planned to be replaced as
part of the Company's technology update strategy. None of these replacements
have been accelerated in response to the Y2K issue and are not anticipated to
have a material effect on the Company consolidated financial statements.
Equipment used for production or quality control does not use dates to control
operations. The costs of this examination to date have been expensed as incurred
and have totaled less than $5,000.

     The Company mailed questionnaires to its significant vendors during the
first quarter of 1999 to determine the extent to which the Company may be
vulnerable to those third parties' failure to remediate their own Y2K issues. It
is anticipated this assessment will be completed during second quarter 1999. The
Company anticipates developing a contingency plan once it has completed its
assessment of significant vendor compliance which it anticipates to be by the
end of second quarter 1999. A contingency plan, if needed, will be developed
during the second half of 1999 to minimize the Company's exposure to work
slowdowns or business disruptions. In the event any vendors are not Y2K
compliant, the Company may seek new vendors to meet its production needs. Any
costs that may be incurred by the Company that are related to external systems
Y2K issues are unknown at this time (other than immaterial costs of the
questionnaire itself). However, management expects that after reviewing and
evaluating the responses to the survey, it will be able to complete an
assessment of its Y2K exposure and estimate the costs associated with resolving
any Y2K issues.

     Although the Company does not at this time expect a significant impact on
its consolidated financial position, results of operations and cash flows, the
assessment has not been completed and there can be no assurance that the systems
of other companies will be converted on a timely basis and will not have a
corresponding adverse effect on the Company.

     The statements set forth above under "Liquidity and Capital Resources" in
this Form 10-Q which are not historical facts are forward-looking statements
including the statements regarding the Company's expected revenue, profitability
and other financial results in 1999 and beyond, the Company's capital needs and
the impact of and the Company's plans with respect to the year 2000. These
forward-looking statements 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, the activities of competitors or the
failure of the Company or third parties to adequately address issues relating to
the year 2000. Additional factors include the Company's ability to realize the
anticipated benefits from the relationship with Caterpillar. 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.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company has no history of, and does not anticipate in the future,
investing in derivative financial instruments, derivative commodity instruments
or other such financial instruments. Transactions with international customers
are entered into in US dollars, precluding the need for foreign currency hedges.
Additionally, the Company invests in money market funds and fixed rate U.S.
government and corporate obligations, which experience minimal volatility. Thus,
the exposure to market risk is not material.

NOTE 1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Interim Financial Information

     The accompanying unaudited 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.

Reclassifications

     Certain 1998 amounts have been reclassified to conform with the
presentation in the 1999 financial statements.

NOTE 2.    SHAREHOLDERS' EQUITY

     On October 14, 1998, the Company entered into a Securities Purchase
Agreement (the Agreement) with Caterpillar Inc. The Agreement was approved by
the Company's shareholders on January 28, 1999 and subsequently closed on
January 29, 1999. Under the terms of the Agreement, Caterpillar acquired, for an
aggregate purchase price of $18,000,000, one million newly issued shares of
common stock and a warrant to purchase an additional 10,267,127 newly issued
shares of common stock at a price of $21.00 per share. The warrant is
exercisable immediately and at any time over the next ten years, subject to
partial termination in the event the Company achieves certain financial goals.
As a result of the Agreement, the board of directors was increased from eight to
ten members with the additional two members appointed by Caterpillar. In
addition, the Agreement contains other provisions which allow Caterpillar to
maintain its proportionate potential ownership and that restricts certain
situations including acquisitions, loans and the payment of dividends, without
approval of at least one of the Caterpillar designated members of the Board.

     The Company and Caterpillar have entered into a Commercial Alliance
Agreement pursuant to which Caterpillar will provide the Company with access to
its dealer network and will make various management, financial and engineering
resources available to the Company. Included in the Commercial Alliance
Agreement is a Marketing Agreement which provides, among other things, that the
Company will pay Caterpillar a commission equal to 5% of the dealer net price
for complete machines and 3% for replacement parts and Company-branded
attachments for all sales made to Caterpillar dealers. In addition, if the
Company's products are sold under the Caterpillar brand name, the Company will
pay Caterpillar a trademark license fee equal to 3% of the net sales of these
products to Caterpillar dealers. The Company and Caterpillar also entered into
other ancillary agreements for the benefit of both the Company and Caterpillar.

     Upon closing, Caterpillar owned approximately 8.8% of the Company's
outstanding common stock (assuming the exercise of all outstanding options and
warrants). Caterpillar will have the right to own up to approximately 52% of the
Company's common stock (assuming the exercise of all outstanding options and
warrants) upon exercise of the warrant.

     The warrant issued to Caterpillar provides for a potential change of
control. As a result, in accordance with the 1994 and 1996 stock option plans,
all previously issued stock options became fully vested upon the closing of the
transaction. As a result of the acceleration, the Company will reflect pro forma
compensation of approximately $4,400,000 in its calculation of pro forma net
income and pro forma net income per share for 1999, in accordance with pro forma
disclosures required by Statement of Financial Accounting Standard No. 123 -
"Accounting for Stock Based Compensation".

     In connection with the Agreement, the Company incurred expenses of
approximately $448,000, which were offset against the proceeds for the issued
shares.

NOTE 3.  CONTINGENCY

     The Year 2000 issue relates to limitations in computer systems and
applications that may prevent proper recognition of the Year 2000. The potential
effect of the Year 2000 issue on the Company and its business partners will not
be fully determinable until the year 2000 and thereafter. If Year 2000
modifications are not properly completed either by the Company or entities with
whom the Company conducts business, the Company's financial condition and
results of operations could be adversely impacted.

                             RESULTS OF OPERATIONS

Results of Operations

     The following table sets forth certain Statements of Earnings data as a
percentage of net sales:

                                                    Three Months Ended March 31,
                                                       1999             1998
                                                       ----             ----
   Net sales......................................    100.0%           100.0%
   Cost of goods sold.............................     73.6%            75.0
   Gross profit...................................     26.4%            25.0
   Selling, general and administrative expenses...     13.2%             9.0
   Operating income...............................     12.0%            15.0
   Interest expense...............................      0.8%             1.4
   Net income.....................................      7.7%             8.8

     Net Sales. For the three months ended March 31, 1999, net sales were
approximately $8,463,000, a decrease of six percent compared with the three
months ended March 31, 1998. This decrease was due to the reduced sales of
Posi-Track vehicles and related accessories due to the continued transition of
distributing the Posi-Track through a primarily independent dealer network to
the Caterpillar dealer network. As of April 23, 1999, the Company has a total of
24 Caterpillar dealers selling Posi-Tracks. Of these 24 dealers, who have 154
locations, 21 are located in the United States, which represents one-third of
all U.S. Caterpillar dealers. The Company's total dealer location count is
approximately 200, compared with approximately 100 at this time last year. Sales
of parts, used equipment and other items increased 39% for the three month
period ended March 31, 1999 as compared with 1998. This increase was due in part
to a 65% increase in the sale of parts as the number of vehicles in the field
has increased. Also, the Company recognized net sales of approximately $665,000
in the first quarter of 1999 for the final subcontract work performed on a
military contract.

     Gross Profit. Gross profit for the three months ended March 31, 1999 was
approximately $2,237,000 compared with approximately $2,258,000 in 1998.
However, the gross profit percentage increased from 25.0% in 1998 to 26.4% in
1999. The increased gross profit percentage can be attributed to a greater
number of units produced in 1999, which resulted in lower fixed costs per unit,
and also improved inventory management.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased from approximately $808,000, or 9.0% of net
sales in 1998, to approximately $1,113,000, or 13.2% of net sales in 1999. These
increases are due primarily to increased marketing costs as well as higher
compensation costs as sales and administrative personnel have been added to
support expanded sales and customer service roles. In addition, with the closing
of the Commercial Alliance Agreement with Caterpillar Inc., the Company began
paying a commission to Caterpillar for sales to Caterpillar dealers as of
January 29, 1999. This commission accounted for slightly over one-half of the
percentage increase in selling, general and administrative expenses.

     Research and Development. Research and development expenses increased from
approximately $98,000 in 1998 to approximately $108,000 in 1999. The increase is
due to the Company devoting more resources to future product alternatives.

     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 decreased from approximately $129,000
for the first quarter of 1998 to approximately $66,000 for the first quarter of
1999. The decrease was the net effect of two factors. First, the Company's
convertible debentures were exchanged for common stock in the fourth quarter of
1998, eliminating future interest expense on the debentures. Second, the Company
utilized its line of credit during the month of January, prior to the closing of
the Caterpillar transaction, to fund operations.

                                       7
Net Income. Net income for the first quarter of 1999 was approximately
$649,000, as compared with approximately $792,000 for the first quarter of 1998.
The decrease in 1999 resulted primarily from slightly reduced sales and
increased operating expenses, offset in part by an increased gross profit
percentage and decreased interest expense.

Liquidity and Capital Resources

     At March 31, 1999, the Company had working capital of approximately
$35,653,000 compared with working capital of approximately $17,416,000 at
December 31, 1998, an increase of approximately $18,237,000. This increase was
due to the sale of common stock and warrant to Caterpillar Inc. in January 1999
for $18 million. The Company used these proceeds primarily to pay off its line
of credit and fund current operations. During the transition to Caterpillar
dealers, the Company chose not to reduce its production levels, but instead,
increased its finished goods. This decision, along with the repurchase of
certain inventory from current and former dealers, caused inventory levels to
increase 39% compared with December 31, 1998. Accounts receivable increased as
extended terms have been offered to certain dealers. Also, approximately
$665,000 was invoiced in March 1999 for the final subcontract work performed on
a military contract.

     On October 14, 1998, the Company entered into a Securities Purchase
Agreement (the Agreement) with Caterpillar Inc. (Caterpillar). The Agreement was
approved by the Company's shareholders on January 28, 1999 and closed January
29, 1999. Under the terms of the Agreement, Caterpillar acquired, for an
aggregate purchase price of $18,000,000, one million newly issued shares of the
Company's common stock and a warrant to purchase an additional 10,267,127
newly-issued shares of the Company's common stock at a price of $21.00 per
share. Also under the terms of the Agreement, the Company's board of directors
was increased from eight to ten with the additional two members appointed as
designated by Caterpillar.

     In connection with entering into the Agreement, the Company and Caterpillar
have entered into several ancillary agreements. These agreements provide the
Company access to Caterpillar's dealer network and also make various management,
financial and engineering resources from Caterpillar available to the Company
following the closing. One of these agreements is a Marketing Agreement which
provides, among other things, that the Company will pay Caterpillar a commission
equal to 5% of the dealer net price for complete machines and 3% for replacement
parts and Company-branded attachments for all sales made to Caterpillar dealers.
Should the Company manufacture products that are sold under the Caterpillar
brand name, the Company will pay Caterpillar a trademark license fee equal to 3%
of the net sales of these products to Caterpillar dealers.

     It is the intent of the Company and Caterpillar to introduce the Company's
Posi-Track products to Caterpillar's North American dealers as soon as
practicable. With the signing and announcement of the Agreement with
Caterpillar, certain of the Company's existing, non-Caterpillar dealers have
been hesitant to place orders for the Company's products. Management believes
these dealers are uncertain of their future status as Posi-Track dealers.
Between the time of the announcement of the Caterpillar transaction and March
1999, approximately 36 dealer locations elected to no longer carry the Company's
products. These 36 locations are comprised of eleven dealers who will no longer
carry the Company's products and two dealers whose Posi-Track trade areas have
been reduced. One of those dealers whose trade area has been reduced was the
Company's largest customer for 1998. This dealer accounted for approximately 21%
of the Company's net sales in 1998. This dealer is a Caterpillar dealer and
their Posi-Track trade area was reduced as they were selling into the trade area
of approximately nine other Caterpillar dealers.

     The Company believes its sales during the first quarter of 1999 decreased
due to the factors discussed above. In addition, several Caterpillar dealers
have chosen to wait until they have received training on the Posi-Track from
factory representatives before placing significant orders. The Company is in the
process of providing this training. The Company believes the slow-down in sales
is temporary and expects the order level to increase as additional Caterpillar
dealers receive training and begin carrying the Posi-Track models. Although the
Company has been working closely with Caterpillar to introduce the Posi-Track
products to North American Caterpillar dealers as quickly as possible, the
Company may experience a decrease in its sales volume while the Company proceeds
through this transitional period with Caterpillar.

     In connection with the replacement of the Company's independent dealers
with Caterpillar dealers, the Company has made arrangements with certain dealers
to repurchase their existing inventory of Posi-Track products and transfer it to
the new Caterpillar dealers. In some instances, it has been necessary for the
Company to take possession of the inventory, rather than transferring it
directly to the new Caterpillar dealer. In these situations, the Company will be
responsible for re-marketing this inventory. The Company does not currently
anticipate a material loss from the re-marketing of this inventory.

                                       8
As a result of the transaction, the Company's near term revenues,
profitability and other financial results are expected to be lower than if the
transaction were not entered into. The decline is related to a number of
factors, including (i) the commission to be paid to Caterpillar for sales made
to Caterpillar dealers, (ii) transition issues affecting orders from the
preexisting non-Caterpillar affiliated dealers, and (iii) certain other costs of
implementing the Transaction and the agreements contemplated by the Commercial
Alliance Agreement. Over the longer term, however, management believes that the
Company will be able to achieve improved financial results due to the
Transaction and the Commercial Alliance Agreement.

     The Company believes its existing cash and marketable securities, 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 for at least the next twelve months.

     Impact of the Year 2000 Issue. The Company has established a team to assess
and address the possible exposures related to the Year 2000 ("Y2K") issue and is
in the initial assessment phase. The areas under investigation include business
computer systems, production equipment, vendor readiness and contingency plans.
The Company does not use internally developed computer software and is therefore
not anticipating major reprogramming efforts. The Company's primary financial
and operational system has been assessed and is certified Y2K compliant. There
are several ancillary applications that may not currently be Y2K compliant, but
the Company expects it will be able to purchase Y2K compliant versions by mid to
late-calendar 1999, the cost of which is not expected to be material. The
majority of the Company's personal computers are currently Y2K compliant. Those
computers that may not currently be Y2K compliant are planned to be replaced as
part of the Company's technology update strategy. None of these replacements
have been accelerated in response to the Y2K issue and are not anticipated to
have a material effect on the Company consolidated financial statements.
Equipment used for production or quality control does not use dates to control
operations. The costs of this examination to date have been expensed as incurred
and have totaled less than $5,000.

     The Company mailed questionnaires to its significant vendors during the
first quarter of 1999 to determine the extent to which the Company may be
vulnerable to those third parties' failure to remediate their own Y2K issues. It
is anticipated this assessment will be completed during second quarter 1999. The
Company anticipates developing a contingency plan once it has completed its
assessment of significant vendor compliance which it anticipates to be by the
end of second quarter 1999. A contingency plan, if needed, will be developed
during the second half of 1999 to minimize the Company's exposure to work
slowdowns or business disruptions. In the event any vendors are not Y2K
compliant, the Company may seek new vendors to meet its production needs. Any
costs that may be incurred by the Company that are related to external systems
Y2K issues are unknown at this time (other than immaterial costs of the
questionnaire itself). However, management expects that after reviewing and
evaluating the responses to the survey, it will be able to complete an
assessment of its Y2K exposure and estimate the costs associated with resolving
any Y2K issues.

     Although the Company does not at this time expect a significant impact on
its consolidated financial position, results of operations and cash flows, the
assessment has not been completed and there can be no assurance that the systems
of other companies will be converted on a timely basis and will not have a
corresponding adverse effect on the Company.

     The statements set forth above under "Liquidity and Capital Resources" in
this Form 10-Q which are not historical facts are forward-looking statements
including the statements regarding the Company's expected revenue, profitability
and other financial results in 1999 and beyond, the Company's capital needs and
the impact of and the Company's plans with respect to the year 2000. These
forward-looking statements 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, the activities of competitors or the
failure of the Company or third parties to adequately address issues relating to
the year 2000. Additional factors include the Company's ability to realize the
anticipated benefits from the relationship with Caterpillar. 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.

                                       9
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company has no history of, and does not anticipate in the future,
investing in derivative financial instruments, derivative commodity instruments
or other such financial instruments. Transactions with international customers
are entered into in US dollars, precluding the need for foreign currency hedges.
Additionally, the Company invests in money market funds and fixed rate U.S.
government and corporate obligations, which experience minimal volatility. Thus,
the exposure to market risk is not material.
