                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (unaudited)


A. BASIS OF PRESENTATION

         The consolidated financial statements are unaudited, other than the
consolidated balance sheet at December 31, 1996, and reflect all adjustments
(consisting only of normal recurring adjustments) which are, in the opinion of
Management, necessary for a fair presentation of the Company's financial
condition, operating results and cash flows for the interim periods.

         The results of operations for the current interim period are not
necessarily indicative of results to be expected for the current year. Certain
items shown in the prior financial statements have been reclassified to conform
with the presentation of the current period.

         The Company operates under a thirteen-week calendar quarter. However,
for financial statement presentation purposes, the reporting periods are
referred to as ended on the last calendar day of the quarter. The accompanying
financial statements for the three and six months ended June 30, 1997 and 1996
are for the thirteen and twenty-six weeks ended June 27, 1997 and June 28, 1996,
respectively.

         Earnings per share are computed using the weighted average number of
shares outstanding and dilutive common stock equivalents (options and warrants).

         These consolidated financial statements should be read in conjunction
with the consolidated financial statements for the year ended December 31, 1996
and the notes thereto in the Company's Annual Report on Form 10-K for the year
ended December 31, 1996.

B. STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS NOT YET ADOPTED

         In February 1997, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings
per Share." This statement requires dual presentation of newly defined basic and
diluted earnings per share ("EPS") on the face of the income statement for all
entities with complex capital structures. The accounting standard is effective
for fiscal years ending after December 15, 1997 and requires restatement of all
prior period EPS data presented. Earlier application is not permitted. However,
disclosure of pro forma EPS data computed using SFAS No. 128 in the notes to the
financial statements is permitted in the periods prior to required adoption. The
pro forma EPS data for the three and six months ended June 30, 1997 and 1996
computed using SFAS No. 128 is as follows (shares in thousands):

                                            Three Months Ended  Six Months Ended

  Diluted.................................  27,588     23,434   27,168  23,354

         In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." This statement establishes standards for the reporting and display of
comprehensive income and its components in a full set of general purpose
financial statements. Comprehensive income generally represents all changes in
shareholders' equity during the period except those resulting from investments
by, or distributions to, shareholders. SFAS No. 130 is effective for fiscal
years beginning after December 15, 1997 and requires restatement of earlier
periods presented. Management is currently evaluating the requirements of SFAS
No. 130.

         In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information." SFAS No. 131 establishes standards
for the way that a public enterprise reports information about operating
segments in annual financial statements, and requires that those enterprises
report selected information about operating segments in interim financial
reports issued to shareholders. SFAS No. 131 is effective for fiscal years
beginning after December 15, 1997 and requires restatement of earlier periods
presented. Management is currently evaluating the requirements of SFAS No. 131.

C. FAIR VALUE OF INVESTMENTS

         The Company has short-term investments in corporate debt securities
with original maturities of less than 90 days whose carrying amounts approximate
their fair values because of their short maturities. These short-term
investments are included in cash and cash equivalents, are classified as
held-to-maturity securities and amounted to $11.8 million and $3.0 million at
June 30, 1997 and December 31, 1996, respectively. At June 30, 1997, the Company
also had investments classified as available-for-sale securities included in
short-term and long-term investments, consisting of $20.1 million of United
States Treasury Notes with maturities of up to two years. These
available-for-sale securities are accounted for at their fair value, and
unrealized gains and losses on these securities are reported as a separate
component of shareholders' equity. At June 30, 1997, unrealized gains or losses
on available-for-sale securities were not significant.

E. RELATED PARTY TRANSACTIONS

           Sales to related parties consist of, and amounts due from related
parties are, the result of transactions between the Company and foreign
affiliates controlled by the Company's Chairman of the Board.


F. INCOME TAXES

         For the three-month and six-month periods ended June 30, 1997, the
Company had tax provisions of $476,000 and $1,245,000, respectively, resulting
in effective tax rates of 12% and 20%, respectively. The provisions for 1997
were primarily foreign taxes on the income of the Company's Japanese subsidiary
and the provision for taxes on the Company's U.S. taxable income at the federal
alternative minimum tax rate and applicable state tax rates. Although the
Company's pre-tax results for the three-month and six-month periods ended June
30, 1996 showed a loss, the Company had tax provisions of $261,000 and $689,000,
respectively, which were principally foreign taxes on the income of the
Company's Japanese subsidiary and reflected the Company's inability to currently
recognize a benefit for its U.S. loss and credits carryforwards, which remain
available to reduce future U.S. taxes. The Company anticipates that it has
sufficient loss and credits carryforwards available to offset most of its
expected U.S. taxes in 1997.

                                   (unaudited)


G. BORROWINGS

         The Company has a $10.0 million line of credit with a U.S. bank and
lines of credit aggregating $3.1 million available to the Company's Japanese
subsidiary from certain Japan-based banks.

         The Company's $10.0 million line of credit is collateralized by
substantially all of the Company's assets, bears interest at, or in some cases
below, the U.S. prime rate (8.5% at June 30, 1997), and expires June 30, 1998,
if not renewed. Under the terms of this facility, the Company is required to
maintain certain financial ratios and meet certain net worth and indebtedness
tests with which the Company is in compliance. There have been no borrowings
under this credit facility.

         The Company's Japanese subsidiary has collateralized yen-denominated
lines of credit with Japan-based banks, primarily available for use in Japan,
amounting to the equivalent of $3.1 million with interest at the Japanese prime
rate (1.625% at June 30, 1997) plus 0.125% per annum which expire between March
31, 1998 and August 5, 1998, if not renewed. There have been no borrowings under
these lines of credit.


H. MAJOR CUSTOMERS

         Sales to NYNEX amounted to 15% of revenues for the second quarter of
1997. Sales to GTE amounted to 21% of revenues for the second quarter of 1996,
and sales to Nippon Telegraph & Telephone amounted to 10% of revenues for the
second quarter of 1996.

         Sales to Nippon Telegraph & Telephone amounted to 11% and 12% of
revenues for the first six months of 1997 and 1996, respectively. Sales to NYNEX
amounted to 13% of revenues for the first six months of 1997 and sales to GTE
amounted to 13% of revenues for the first six months of 1996.


I. COMMON STOCK

           On July 24, 1997, the Company's Board of Directors approved a
two-for-one stock split of the Company's common stock. The additional stock will
be distributed on August 22, 1997 to shareholders of record on August 8, 1997.
All references to numbers of shares and related prices, and per share amounts
have been restated to reflect the stock split.

               THREE MONTHS ENDED JUNE 30, 1997 COMPARED WITH THE
                        THREE MONTHS ENDED JUNE 30, 1996

         Revenues. The Company's revenues increased by $8.2 million, or 49%,
during the second quarter of 1997 due to higher sales of network switching
products and intelligent network diagnostics products.

         Revenues from switching products increased by $6.8 million, or 95%, in
the second quarter of 1997 primarily due to an 86% increase in EAGLE STP unit
sales as a result of increased market acceptance principally in the U.S.
Additionally, EAGLE STP average selling price increased as a result of the
Company's sales of larger systems in the Regional Bell Operating Company (RBOC)
market. The Company expects that its switching product revenues will continue to
grow both in dollars and as a percentage of revenues for the remainder of 1997
when compared to 1996.

         Revenues from intelligent network diagnostics products increased by
$1.5 million, or 28%, due primarily to increased MGTS product sales in the U.S.

         Revenues from data network diagnostics products decreased by $100,000,
or 2%. The Company has taken steps to expand its Chameleon products' reach into
the network operator market including the planned introduction, in the second
half of 1997, of software applications addressing specific needs of this market
which could provide additional sales opportunities.

         Revenues in North America increased by $7.6 million, or 72%, primarily
as a result of higher EAGLE STP and MGTS product sales. Sales in Japan increased
by $281,000, or 9%, primarily due to higher Chameleon product sales, partially
offset by unfavorable exchange rate fluctuations on foreign currency
translations. Other international revenues increased by $292,000 or 9%.

                                       12


         The impact of exchange rate fluctuations on foreign currency
translations decreased revenues by approximately $400,000, or 2%, and decreased
net income by $26,000, or 1%, in the second quarter of 1997.

         The Company believes that its future revenue growth depends in large
part upon a number of factors, including the continued market acceptance of the
Company's products, particularly the EAGLE STP product and the successful
introduction of new applications such as the Company's EAGLE STP/Local Number
Portability feature.

         Gross Profit. Gross profit as a percentage of revenues increased from
60% in the second quarter of 1996 to 64% in the second quarter of 1997,
primarily due to higher switching product margins and improved manufacturing
efficiencies due to higher sales volumes. These factors were partially offset by
a lower proportion of diagnostics product sales, which typically carry higher
margins than switching products.

         Research and Development. Although research and development expenses
increased by $417,000, or 10%, in the second quarter of 1997, such expenses
decreased as a percentage of revenues from 26% in the second quarter of 1996 to
19% in the second quarter of 1997. The dollar increase was due to increased
switching product expenses of approximately $800,000, partially offset by lower
research and development spending for diagnostics products. This increase was
primarily attributable to ongoing development expenses for the Company's local
number portability feature on the EAGLE STP product and consisted principally of
expenses incurred in connection with the hiring of additional personnel and
contractors and higher depreciation expenses as a result of equipment
acquisitions. Based on expected revenues and expense levels, the Company
believes that research and development expenses will continue to be lower as a
percentage of revenues for the remainder of 1997 when compared with 1996.

         Selling, General and Administrative Expenses. Although selling, general
and administrative expenses increased by $612,000, or 8%, in the second quarter
of 1997, such expenses decreased as a percentage of revenues from 43% in the
second quarter of 1996 to 32% in the second quarter of 1997. The dollar increase
was due primarily to the accrual of certain costs for performance-related award
programs and increased support infrastructure costs to meet the requirements of
the growing EAGLE installed base and higher sales levels. Based on expected
revenues and expense levels, the Company believes that selling, general and
administrative expenses will continue to be lower as a percentage of revenues
for the remainder of 1997 when compared with 1996.

         Income Taxes. For the three-month period ended June 30, 1997, the
Company had a tax provision of $476,000, resulting in an effective tax rate of
12%. The provision for 1997 was primarily foreign taxes on the income of the
Company's Japanese subsidiary and the provision for taxes on the Company's U.S.
taxable income at the federal alternative minimum tax rate and applicable state
tax rates. Although the Company's pre-tax results for the three-month period
ended June 30, 1996 showed a loss, the Company had a tax provision of $261,000
for such period. This provision was principally foreign taxes on the income of
the Company's Japanese subsidiary and reflected the Company's inability to
currently recognize a benefit for its U.S. loss and credits carryforwards, which
remain available to reduce future U.S. taxes. The Company anticipates that

                                       13


it has sufficient loss and credits carryforwards available to offset most of its
expected U.S. taxes in 1997.


                SIX MONTHS ENDED JUNE 30, 1997 COMPARED WITH THE
                         SIX MONTHS ENDED JUNE 30, 1996

         Revenues. The Company's revenues increased by $16.9 million, or 59%,
during the first six months of 1997 due primarily to higher sales of network
switching products and intelligent network diagnostics products. Sales of data
network diagnostics products decreased both in dollars and as a percentage of
total sales.

         Revenues from switching products increased by $13.1 million, or 133%,
primarily due to a 90% increase in EAGLE STP unit sales as a result of increased
market acceptance primarily in the U.S. Additionally, EAGLE STP average selling
price increased as a result of the Company's sales of larger systems in the
Regional Bell Operating Company (RBOC) market.

         Revenues from intelligent network diagnostics products increased by
$6.0 million, or 70%, primarily due to strong demand for the Company's MGTS
products particularly in the domestic and Japanese wireless markets.

         Revenues from data network diagnostics products, which consisted
primarily of sales to the research and development market, decreased by $2.2
million, or 22%, due primarily to lower worldwide sales in the first quarter of
1997 of the Company's Chameleon products.

         Revenues in North America increased by $14.9 million, or 89%, primarily
as a result of higher EAGLE STP and MGTS product sales. Sales in Japan increased
by $1.7 million, or 27%, due primarily to higher MGTS product sales, partially
offset by unfavorable exchange rate fluctuations on foreign currency
translations. Other international revenues increased by $320,000 or 6%.

         The impact of exchange rate fluctuations on foreign currency
translations decreased revenues by $1.1 million, or 2%, and decreased the
Company's net income by $102,000, or 2%, in the first six months of 1997.

         Gross Profit. Gross profit as a percentage of revenues increased from
61% in the first half of 1996 to 66% in the first half of 1997, primarily due to
higher switching product margins and improved manufacturing efficiencies as a
result of higher sales volumes. These factors were partially offset by a lower
proportion of diagnostics product sales, which typically carry higher margins
than switching products. In addition, switching product margins in the first
half of 1996 were adversely impacted by certain non-recurring costs.

         Research and Development. Although research and development expenses
increased overall by $570,000, or 7%, in the first six months of 1997, such
expenses decreased as a

                                       14


percentage of revenues from 30% in the first six months of 1996 to 20% in the
first six months of 1997. The dollar increase in such expenses was primarily
attributable to ongoing development expenses for the Company's local number
portability solution on the EAGLE STP product and consisted principally of
expenses incurred in connection with the hiring of additional personnel and
contractors and higher depreciation expenses as a result of equipment
acquisitions. This increase was partially offset by lower research and
development spending for diagnostics products.

         Selling, General and Administrative Expenses. Although selling, general
and administrative expenses increased by $1.3 million, or 9%, in the first six
months of 1997, such expenses decreased as a percentage of revenues from 49% in
the first six months of 1996 to 34% in the first six months of 1997. The dollar
increase in such expenses was primarily due to increased support infrastructure
costs to meet the requirements of the growing EAGLE installed base and higher
sales levels, and the accrual of certain costs for performance-related award
programs.

         Income Taxes. For the six-month period ended June 30, 1997, the Company
had a tax provision of $1.2 million, resulting in an effective tax rate of 20%.
The provision for 1997 was primarily foreign taxes on the income of the
Company's Japanese subsidiary and the provision for taxes on the Company's U.S.
taxable income at the federal alternative minimum tax rate and applicable state
tax rates. Although the Company's pre-tax results for the six-month period ended
June 30, 1996 showed a loss, the Company had a tax provision of $689,000 for
such period. This provision was primarily foreign taxes on the income of the
Company's Japanese subsidiary and reflected the Company's inability to currently
recognize a benefit for its U.S. loss and credits carryforwards, which remain
available to reduce future U.S. taxes.


         LIQUIDITY AND CAPITAL RESOURCES

         During the six months ended June 30, 1997, cash and cash equivalents
increased by $8.1 million to $25.3 million, primarily due to a net transfer of
approximately $6.9 million from short-term and long-term investments. In
addition, financing activities provided $3.3 million, operating activities,
including the effects of exchange rate changes on cash, provided $1.1 million
while capital expenditures used $3.3 million.

         Accounts receivable, including amounts due from related parties,
increased by 33% during the first six months of 1997 due primarily to higher
sales levels and $6.7 million in accounts receivable billings for which revenue
had not yet been recognized. These billings primarily represented shipments to
customers for which revenue recognition is dependent upon customer acceptance,
which had not yet occurred at June 30, 1997. Inventories increased by 59% during
the first six months of 1997 primarily to meet customer shipments scheduled for
the third quarter of 1997 and product requirements for customer trials. Deferred
revenues increased by 177% primarily due to shipments to customers with extended
acceptance periods.

         Capital expenditures amounted to $3.3 million during the first six
months of 1997 and represented the planned addition of equipment principally for
EAGLE research and development.

                                       15


         The net cash provided by financing activities in the first six months
of 1997 amounted to $3.3 million which represented net proceeds from the
issuance of Common Stock upon the exercise of stock options and warrants.

         The Company has a $10.0 million line of credit with a U.S. bank and
lines of credit aggregating $3.1 million available to the Company's Japanese
subsidiary from certain Japan-based banks.

         The Company's $10.0 million line of credit is collateralized by
substantially all of the Company's assets, bears interest at, or in some cases
below, the U.S. prime rate (8.5% at June 30, 1997), and expires June 30, 1998,
if not renewed. Under the terms of this facility, the Company is required to
maintain certain financial ratios and meet certain net worth and indebtedness
tests for which the Company is in compliance. There have been no borrowings
under this credit facility.

         The Company's Japanese subsidiary has collateralized yen-denominated
lines of credit with Japan-based banks, primarily available for use in Japan,
amounting to the equivalent of $3.1 million with interest at the Japanese prime
rate (1.625% at June 30, 1997) plus 0.125% per annum which expire between March
31, 1998 and August 5, 1998, if not renewed. There have been no borrowings under
these lines of credit.

         Upon the expiration of the above-described credit facilities, the
Company believes that, if necessary, it would be able to arrange for credit
facilities on terms generally no less favorable than those described above.

         The Company believes that existing working capital, funds generated
from operations, and its current bank lines of credit should be sufficient to
satisfy anticipated operating requirements at least through 1997.


         STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NOT YET ADOPTED

         In February 1997, the Financial Accounting Standards Board ("FASB") 
issued Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings 
per Share." This statement requires dual presentation of newly defined basic and
diluted earnings per share ("EPS") on the face of the income statement for all
entities with complex capital structures. The accounting standard is effective
for fiscal years ending after December 15, 1997 and requires restatement of all
prior period EPS data presented. Earlier application is not permitted. The
Company has determined that in some periods the presentation of basic EPS data
under SFAS No. 128 may differ significantly from previously reported EPS data as
a result of the exclusion of dilutive common stock equivalents (options and
warrants) in the basic EPS calculation. See Note B for further information and
the pro forma impact on EPS data for the periods ending June 30, 1997 and 1996.

         In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." This statement establishes standards for the reporting and display of
comprehensive income and its components in a full set of general purpose
financial statements. Comprehensive income generally represents all changes in
shareholders' equity during the period except those resulting from

                                       16


investments by, or distributions to, shareholders. SFAS No. 130 is effective for
fiscal years beginning after December 15, 1997 and requires restatement of
earlier periods presented. Management is currently evaluating the requirements
of SFAS No. 130.

         In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information." SFAS No. 131 establishes standards
for the way that a public enterprise reports information about operating
segments in annual financial statements, and requires that those enterprises
report selected information about operating segments in interim financial
reports issued to shareholders. SFAS No. 131 is effective for fiscal years
beginning after December 15, 1997 and requires restatement of earlier periods
presented. Management is currently evaluating the requirements of SFAS No. 131.
