                      ELECTRONIC TELE-COMMUNICATIONS, INC.
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

Net sales were $3,369,368 and $2,875,246 for the three-month periods ended June
30, 2000 and 1999, respectively. Net sales for the six-month period ended June
30, 2000 were $6,465,780, compared to $6,144,353 for the corresponding period of
1999. The increase in net sales for the 2000 periods was due to increased demand
for the Company's interactive voice information systems, particularly its
flagship Digicept DNA product line. The increased demand came from competitive
and independent local exchange carriers upgrading and adding to their
telecommunications infrastructures. Increases in DNA sales were partially offset
by lower sales in 2000 of System 3 upgrades and Interact systems that were sold
in 1999 to meet customers' Y2K needs. Revenues from sales of the Company's
interactive voice information systems were $4,442,854 or 69% of net sales, and
$3,747,300 or 61% of net sales, for the six-month periods ended June 30, 2000
and 1999, respectively. Revenues from operating leases, installment sales
contracts, and services were consistent between periods at $1,811,826 or 28% of
net sales for the 2000 six-month period, compared to $1,838,721 or 30% of net
sales for the corresponding 1999 six-month period. Product pricing for the
Company's equipment remained relatively constant between periods, and inflation
did not have a material impact on revenues.

For the three-month periods ended June 30, 2000 and 1999, the gross profit
percentage was 52% and 50%, respectively. Gross profit as a percentage of net
sales for the six-month periods ended June 30, 2000 and 1999, were 50% and 51%,
respectively. The increase in gross profit percentage in the 2000 three-month
period was due to primarily to the effect of spreading fixed manufacturing costs
over higher sales volume in the 2000 three-month period. The decrease in gross
profit percentage in the 2000 six-month period was due to the effect of higher
1999 sales of various Y2K upgrades which have a higher profit margin than the
Company's normal product mix.

For the three-month periods ended June 30, 2000 and 1999, total operating
expenses were $1,508,591 or 45% of net sales, and $1,398,165 or 49% of net
sales, respectively. Total operating expenses were $2,853,754 or 44% of net
sales for the six-month period ended June 30, 2000, compared to $2,827,620 or
46% for the corresponding period of 1999. General and administrative expenses
and research and development expenses were relatively constant between periods.
Marketing and selling expenses increased in the three-month period ended June
30, 2000 due primarily to higher commission expenses paid on higher sales,
higher advertising costs related to new products, and higher convention expenses
related to the Supercom convention in April 2000, but decreased as a percentage
of sales. For the six-month periods ended June 30, 2000 and 1999, marketing and
selling expenses remained relatively constant.

Net other expenses were $11,970 for the six-month period ended June 30, 2000,
compared to net other income of $1,888 for the corresponding six-month period of
1999. The increase between periods of net other expenses was primarily due to
more interest expense incurred for bank borrowings during the 2000 six-month
period and higher interest income earned from investing Company funds in the
1999 six-month period.

For the three-month periods ended June 30, 2000 and 1999, net earnings were
$217,500 and $23,965, respectively. Higher net earnings for the 2000 quarter
were due to higher sales, higher gross margins, and a lower effective tax rate,
partially offset by higher marketing and selling costs. Net earnings for the
six-month period ended June 30, 2000 were $294,178 compared to net earnings of
$201,823 for the corresponding 1999 period. Higher earnings in the 2000
six-month period were due to higher sales and a lower effective tax rate,
partially offset by lower gross margins. The lower effective tax rate in the
2000 periods was due to the use of net operating loss carryforwards from prior
years to offset current year income tax expenses, and a reduction of the
valuation reserve relating to the utilized net operating loss carryforwards.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                   (CONTINUED)

LIQUIDITY AND SOURCES OF CAPITAL

Working capital was $2,709,438 as of June 30, 2000, compared to $2,300,359 at
December 31, 1999. The increase in working capital was due primarily to net
earnings, partially offset by expenditures made for capital equipment. Cash used
in operating activities was $61,550 for the six-month period ended June 30,
2000, compared to cash provided by operating activities of $1,150,965 for the
corresponding 1999 six-month period. The cash used in operating activities in
the 2000 period was due primarily to an increase in accounts receivable,
partially offset by net earnings and refunds of income taxes. The significant
increase in accounts receivable was due to the timing of sales in June 2000 that
were not yet due or paid as of June 30, 2000. Cash provided by operating
activities in the 1999 six-month period was due primarily to net earnings and a
large decrease in accounts receivable, partially offset by an increase in
inventories. The large decrease in accounts receivable in the 1999 six-month
period was due to large sales in the fourth quarter of 1998 that were paid in
early 1999.

For the six-month period ended June 30, 2000, cash provided by net earnings and
an increase in accounts payable and accrued expenses was used to finance an
increase in accounts receivable and purchases of capital equipment. For the 1999
six-month period, cash provided by net earnings and a decrease in accounts
receivable was used for repayment of bank borrowings, payment of dividends,
purchases of capital equipment, and increases in inventories.

As of June 30, 2000, the Company had borrowings of $240,000 on its available
$3,500,000 revolving credit facility. The revolving credit facility expired on
June 30, 2000 and was renewed on July 1, 2000 with a new $4,000,000 credit
facility that expires on June 30, 2003.

At current operating levels, management believes that cash generated from future
operations, together with the available revolving credit facility, will provide
adequate funds to meet the Company's operating needs for the foreseeable future.

                           PART II - OTHER INFORMATION


ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company does not use derivative financial instruments for speculative or
trading purposes. The Company is exposed to market risk related to changes in
short-term interest rates as a result of borrowings under its revolving credit
facility. However, due to the short-term nature and low amount of borrowings,
any impact on the Company's earnings due to changes in interest rates would be
insignificant.
