3. NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities," which is
required to be adopted in years beginning after June 15, 1999. Because the
Company has not used derivatives in the past and does not expect to do so in the
future, the Company does not anticipate that adoption of SFAS No. 133 will have
an effect on it results of operations or financial position.

In March 1998, the AICPA issued SOP 98-1, "Accounting For the Costs of Computer
Software Developed For or Obtained For Internal Use." The SOP, which has been
adopted prospectively as of January 1, 1999, requires the capitalization of
certain costs incurred in connection with developing or obtaining internal use
software. The Company does not develop its own software for internal use. Prior
to the adoption of the SOP 98-1, the Company capitalized the cost of software it
obtained for internal use, and amortized it using the straight-line method over
the useful life of the software. The Company will continue to follow this
practice in accordance with the SOP. Adoption of SOP 98-1 will not have an
impact on the financial statements of the Company.

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


RESULTS OF OPERATIONS

Net sales were $2,875,246 and $3,209,765 for the three-month periods ended June
30, 1999 and 1998, respectively. Net sales for the six-month period ended June
30, 1999 were $6,144,353, compared to $5,856,182 for the corresponding period of
1998. The decrease in net sales for the three-month period ended June 30, 1999,
was due to weaker than expected sales of the Company's interactive voice
information systems to operating telephone companies, original equipment
manufacturers, and competitive local exchange carriers (CLEC's). However, for
the six-month period ended June 30, 1999, sales of the Company's interactive
voice information systems were higher than the prior year comparable period due
to a strong 1999 first quarter. Revenues from sales of the Company's interactive
voice information systems were $3,747,300 or 61% of net sales, and $3,261,689 or
56% of net sales, for the six-month periods ended June 30, 1999 and 1998,
respectively. Revenues from operating leases, installment sales contracts, and
services were $1,838,721 or 30% of net sales for the 1999 six-month period,
compared to $1,797,617 or 31% of net sales for the corresponding 1998 period.
The dollar increase between years was primarily due to increased revenues from
new installment sales contracts, and increased revenue from installation of the
Company's interactive voice information systems. 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, 1999 and 1998, the gross profit
percentage was 50% and 49%, respectively. Gross profit as a percentage of net
sales for the six-month periods ended June 30, 1999 and 1998, were 51% and 46%,
respectively. The increase in gross profit percentage in the 1999 three-month
periods was due to higher sales of various Y2K upgrades which have a higher
profit margin than the Company's normal product mix, partially offset by
spreading fixed manufacturing costs over lower sales volume. The increase in the
six-month periods was due to spreading fixed manufacturing costs over higher
sales volume, and 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, 1999 and 1998, total operating
expenses were $1,390,593 or 48% of net sales, and $1,427,051 or 44% of net
sales, respectively. Total operating expenses were $2,812,477 or 46% of net
sales for the six-month period ended June 30, 1999, compared to $2,877,949 or
49% for the corresponding period of 1998. General and administrative expenses
were lower for the 1999 periods as a result of lower staffing. Marketing and
selling expenses increased in 1999 over 1998 due primarily to salary and benefit
expenses related to previously open sales and marketing positions that were more
fully staffed during the 1999 periods. Research and development expenses were
slightly lower in the 1999 periods due to open engineering positions.

Net other expenses were $13,255 for the six-month period ended June 30, 1999,
compared to $43,988 for the corresponding period of 1998. The decrease between
periods was primarily due to less interest expense incurred for bank borrowings
during the 1999 periods and higher interest income earned from investing Company
funds. Miscellaneous other expense consists primarily of amortization of
goodwill.

For the three-month periods ended June 30, 1999 and 1998, net earnings were
$23,965 and $52,034, respectively. Lower net earnings for the 1999 quarter were
due to lower net sales, partially offset by higher gross margins, lower
operating expenses, and lower interest expense. Net earnings for the six-month
period ended June 30, 1999 were $201,823 versus a net loss of $192,049 for the
corresponding 1998 period. Higher earnings in the 1999 period were attributable
to higher sales, higher gross profit margin on products sold, lower operating
expenses, and lower interest expense.

                                   (CONTINUED)


LIQUIDITY AND SOURCES OF CAPITAL

Working capital was $2,857,360 as of June 30, 1999, compared to $2,759,330 at
December 31, 1998. The slight increase in working capital was due primarily to
net earnings, partially offset by payment of dividends and expenditures made for
capital equipment. Cash provided by operating activities was $1,150,965 for the
six-month period ended June 30, 1999, compared to cash used of $893,811 for the
corresponding 1998 period. The cash provided by operating activities in the 1999
period was due primarily to net earnings and a decrease in accounts receivable,
partially offset by an increase in inventories. Cash used in operating
activities in the 1998 period was due primarily to the net loss, increases in
accounts receivable and inventories, and investment in installment sales
contracts, partially offset by an increase in accounts payable and accrued
expenses.

For the six-month period ended June 30, 1999, cash provided by net earnings and
reduction of accounts receivable was used for repayment of bank borrowings,
payment of dividends, purchases of capital equipment, and increases in
inventories. For the 1998 six-month period, cash provided by bank borrowings was
used for payment of dividends, purchases of capital equipment, and to fund
increased accounts receivable and the net loss.

As of June 30, 1999, the Company had no borrowings on its available $3,500,000
revolving credit facility. The revolving credit facility expires on June 30,
2000.

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


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 ETC's internal
operating computer programs had time-sensitive software that recognized a date
using "00" as the year 1900 rather than the year 2000. This could have caused
system failure or miscalculations causing disruptions of operations, including,
among other things, a temporary inability to process transactions, send
invoices, or engage in similar normal business activities. In addition, ETC's
products contain computer programs that may be impacted by the Year 2000 Issue.
The Company also deals with third parties that may be affected by the Year 2000
Issue and may subsequently affect ETC.

ETC has completed its assessment of the Year 2000 Issue in regard to its
internal computer systems and has modified and replaced minor portions of its
software so that its computer systems will function properly with respect to
dates in the year 2000 and thereafter. The project has been completed, and the
Company believes that with these modifications to existing software and
conversions to new software, the Year 2000 Issue will not pose significant
operational problems for its computer systems.

The Company has completed evaluation of its products and has determined that all
of its current systems are Year 2000 compliant. For any customers that possess
ETC equipment that is currently not Year 2000 compliant, the Company will
provide upgrades or migration paths to new equipment to address the Year 2000
needs of its customers.

                                   (CONTINUED)


ETC is continuing to evaluate the Year 2000 readiness of its critical third
party suppliers. If it is determined that any suppliers are not Year 2000 ready,
ETC will continue to monitor the situation and take appropriate action. Based on
current progress, ETC does not anticipate any adverse consequences due to
supplier Year 2000 readiness.

The total year 2000 project cost is expected to be minimal and all costs will be
expensed as incurred and are included within the Company's normal operating
budget. Computer system software upgrades are included under normal maintenance
contracts

ETC believes, based on an overall analysis of the Year 2000 Issue, that it will
be able to manage its total Year 2000 transition without any adverse effect on
its business operations, products or financial prospects. However, the actual
results could differ and if such modifications and conversions are not made or
are not completed timely, the Year 2000 Issue could have a material impact on
the operations of the Company.
