(1) The effect of all stock options have been excluded from the calculation of
earnings per share for the three months and six months ended December 31, 2000
and 1999, as the average trading price of the Company's common stock during
these periods were less than the exercise price of the stock options.


C.       Revolving Line of  Credit

On February 23, 2000, the Company entered into a revolving credit facility with
its president and major stockholder, and in September 2000 the Company's
president and major stockholder agreed to extend the loan agreement to February
28, 2002, and to increase the loan limit to $1,250,000 in secured financing.
Loan availability is subject to a borrowing limit equal to 80% of eligible
receivables. The revolving credit facility contains various restrictive
covenants including a minimum tangible net worth balance of $2.0 million. As of
February 12, 2001 the Company had $498,000 available under the


                                     6
<PAGE>

revolving credit facility. Interest on outstanding borrowings under the
revolving credit facility is accrued at the Wells Fargo Bank prime interest
rate plus 3%. Additionally, the Company is required to issue warrants on the
Company's stock to the president and major shareholder for incremental
increases in the outstanding borrowings balance. One warrant is issued for
every $4 in incremental borrowings made by the Company. All warrants issued
expire in 4 years and have an exercise price equal to the fair market value
of the Company's stock at the date of grant. Once repayments on the facility
have been made, additional warrants are issued for incremental borrowings on
the facility only to the extent that the new outstanding borrowings balance
exceeds the previous high outstanding borrowings balance. The Company
recorded interest expense of $30,000 for the six months ended December 31,
2000 related to the warrants.


                  ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

Revenue increased by $165,000, or 9%, for the three months ended December 31,
2000, and decreased $354,000, or 8%, for the six months ending December 31,
2000, compared to like periods in the prior year.

Over the past several years the Company has seen a decline in sales and a
decline in unit order size for several of its mature products. In March 2000 the
Company informed several of its customers of its unwillingness to accept low
volume orders and its intention to discontinue maintenance of manufacturing
capacity for several products if order unit size did not increase. The result of
the customer notification has been an increase in sales for mature products in
the quarter ended December 31, 2000 over the prior year quarter. The decrease in
sales for the six month period ended December 31, 2000, over the prior year six
month period, was attributable to a one time order of $700,000 shipped in August
and September of 1999, partially offset by the increase in sales of mature
products in the current six month period. The Company's revenues and earnings
for the quarter ended and six months ended December 31, 2000 are not necessarily
indicative of those for future periods.

 The gross margin percentage for the quarter ended December 31, 2000, was 30%,
compared to 21%, for the same quarter ended December 31, 1999. The gross margin
percentage for the six months ended December 31, 2000, was 35%, compared to 25%,
for the six months ended December 31, 1999. Increased order size on certain
mature monochrome products, and cost reduction efforts, contributed to the gross
margin increase for both the quarter ended December 31, 2000 and the six month
period ended December 31, 2000, compared to the same periods in the prior year.

Selling, general, and administrative expenses decreased $340,000, or 40%, for
the quarter ended December 31, 2000, and $385,000, or 25%, for the six months
ended December 31, 2000, when compared to the same periods in the prior year.
The decrease was due to significant expense reduction efforts.

Interest expense decreased $3,000, or 8%, during the quarter ended December 31,
2000, and $1,000, or 1%, for the six months ended December 31, 2000, compared to
the same periods of the prior year.

LIQUIDITY AND CAPITAL RESOURCES

On February 23, 2000, the Company entered into a revolving credit facility with
its president and major stockholder, and in September 2000 the Company's
president and major stockholder agreed to extend the loan agreement to February
28, 2002, and to increase the loan limit to $1,250,000 in secured financing.
Loan availability is subject to a borrowing limit equal to 80% of eligible
receivables. The revolving credit facility contains various restrictive
covenants including a minimum tangible net worth balance of $2.0 million. As of
February 12, 2001 the Company had $498,000 available under the the revolving
credit facility. Interest on outstanding borrowings under the revolving credit
facility is accrued at the Wells Fargo Bank prime interest rate plus 3%.

Company management believes that the cash and cash equivalents on hand at
February 12, 2001 and future amounts available under the aforementioned credit
agreement should be adequate to meet cash requirements for the next quarter.

During the six months ended December 31, 2000, cash flow from operating
activities was $164,000. During the same period $14,000 of cash was used in the
purchase of property, plant, and equipment. Payment of capital lease obligations
used $28,000 of cash. An increase in borrowings on the working capital loan
contributed $115,000 to Company cash. The overall result was an increase in cash
of $237,000.


COMMON STOCK LISTING

The Company's Common Stock previously was quoted on the NASDAQ Stock Market
under the symbol "DOTX". Effective August 4, 1999 the Company's Common Stock
