5.   New Financial Accounting Standards

     Statement of Financial Accounting Standards (SFAS) No. 133, Accounting for
Derivative Instruments and Hedging Activities, is effective for all fiscal years
beginning after June 15, 2000. SFAS 133, as amended, establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. Under SFAS
133, certain contracts that were not formerly considered derivatives may now
meet the definition of a derivative. The Company adopted SFAS 133 effective
January 1, 2001. Management has concluded that the adoption of SFAS 133 will not
have a significant impact on the financial position, results of operations, or
cash flows of the Company.

Management's Discussion and Analysis of Financial Condition and Results of
Operations

          The Company's quarterly and annual operating results are affected by a
     wide variety of factors that could materially and adversely affect revenues
     and profitability including the following: (a) the risk that the Company
     may be unable to respond adequately to rapidly changing technological
     developments in its industry, (b) risks associated with its Far East
     operations, (c) the highly competitive nature of the Company's industry and
     the impact that competitors' new products and pricing may have upon the
     Company, (d) the likelihood that revenues may vary significantly from one
     accounting period to another accounting period due to a variety of factors,
     including customers' buying decisions, the Company's product mix and
     general market and economic conditions, (e) the Company's reliance on
     certain substantial customers, (f) risks associated with the Company's
     ability to manufacture and deliver products in a manner that is responsive
     to its customers' needs and (g) market and competitive factors impacting
     the Company's customers. As a result of these and other factors, the
     Company may experience material fluctuations in future operating results on
     a quarterly or annual basis, which could materially and adversely affect
     its business, financial condition, operating results, and stock prices.
     Furthermore, this document and other documents filed by the Company with
     the Securities and Exchange Commission (the "SEC") contain certain
     Forward-Looking Statements under the Private Securities Litigation Reform
     Act of 1995 ("Forward-Looking Statements") with respect to the business of
     the Company. These Forward-Looking Statements are subject to certain risks
     and uncertainties, including those mentioned above, and those detailed in
     Item 1 of the Company's Annual Report on Form 10-K for the year ended
     December 31, 2000, which could cause actual results to differ materially
     from these Forward-Looking Statements. The Company undertakes no obligation
     to publicly release the results of any revisions to these Forward-Looking
     Statements which may be necessary to reflect events or circumstances after
     the date hereof or to reflect the occurrence of unanticipated events. An
     investment in the Company involves various risks, including those mentioned
     above and those which are detailed from time to time in the Company's SEC
     filings.

Three Months ended March 31, 2001 vs.
   Three Months ended March 31, 2000

     Net Sales

     Net sales increased 29.0% from $26,133,179 during the first three months of
2000 to $33,703,785 during the first three months of 2001. The Company
attributes this increase principally to higher sales of new products, including
integrated connector modules ("ICM") and xDSL products.

     Several of the Company's customers are facing difficult market conditions.
Some customers have delayed purchase orders, while others have cancelled
purchase orders outright. As a result of these potential difficulties, the
Company does not believe that second quarter 2001 revenue levels or earnings
will reach first quarter 2001 levels.

     Cost of Sales

     Cost of sales as a percentage of net sales decreased 3.8% to 60.1% during
the first three months of 2001 from 63.9 % during the first three months of
2000. The decrease in the cost of sales percentage is primarily attributable to
lower labor and factory overhead expenses and higher sales volume which results
in greater manufacturing efficiencies offset, in part, by higher raw material
content associated with the current sales mix.

     Selling, General and Administrative Expenses

     The percentage relationship of selling, general and administrative expenses
to net sales decreased 3.1% to 16.7% during the first three months of 2001 from
19.8 % during the first three months of 2000. The Company attributes the
percentage decrease primarily to increased sales as well as to structural steps
taken in late 2000 to reduce its selling, general and administrative costs.
Selling, general and administrative expenses increased in dollar amount by
approximately 8.8%. The Company attributes the increase in dollar amount of such
expenses primarily to increases in sales and marketing salaries and related
expenses.

     Other Income and Expense

     Other income, consisting principally of gain on the sale of marketable
securities, during the first three months of 2000, and interest earned on cash
equivalents, decreased by approximately $651,000 during the first three months
of 2001 compared to the first three months of 2000. The decrease is due to the
$1.0 million gain on the sale of marketable securities during the quarter ended
March 31, 2000 offset by higher interest income due to higher cash and cash
equivalent balances.

     Provision for Income Taxes

     The provision for income taxes for the first three months of 2001 was
$1,056,000 as compared to $1,264,000 for the first three months of 2000. The
decrease in the provision is due primarily to lower United States taxes
resulting from the gain on the sale of marketable securities in 2000 versus 2001
offset, in part, by higher foreign earnings subject to taxes in 2001 versus
2000.

                                      -12-




     Liquidity and Capital Resources

     Historically, the Company has financed its capital expenditures through
cash flows from operating activities. Management believes that the cash flow
from operations, combined with its existing capital base and the Company's
available lines of credit, will be sufficient to fund its operations for the
near term. This statement represents a Forward-Looking Statement. Actual results
could differ materially from such statement if the Company experiences
substantial unanticipated cash requirements.

     The Company has lines of credit, all of which were unused at March 31,
2001, in the aggregate amount of $14 million, of which $12 million is from
domestic banks and $2 million is from foreign banks.

     The Company has contracted for the renovation and addition of new corporate
offices in Jersey City in the amount of $2.5 million. As of March 31, 2001
approximately $2.2 million has been paid towards this contract.

     On May 10, 2000 the Board of Directors authorized the repurchase of up to
10% of the Company's outstanding shares. To date the Company purchased and
retired 23,600 Class B common shares at a cost of approximately $808,000, which
reduced the number of Class B common shares outstanding.

     During the first three months of 2001, the Company's cash and cash
equivalents increased by approximately $1.4 million, reflecting approximately
$4.1 million provided by operating activities, offset, in part, by approximately
$2.7 million in purchases of plant and equipment.

     Cash and cash equivalents and accounts receivable comprised approximately
49.0% and 51.9% of the Company's total assets at March 31, 2001 and December 31,
2000, respectively. The Company's current ratio (i.e., the ratio of current
assets to current liabilities) was 8.5 to 1 and 5.5 to 1 at March 31, 2001 and
December 31, 2000, respectively.

New Financial Accounting Standards

     Statement of Financial Accounting Standards (SFAS) No. 133, Accounting for
Derivative Instruments and Hedging Activities, is effective for all fiscal years
beginning after June 15, 2000. SFAS 133, as amended, establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. Under SFAS
133, certain contracts that were not formerly considered derivatives may now
meet the definition of a derivative. The Company adopted SFAS 133 effective
January 1, 2001. Management has concluded that the adoption of SFAS 133 will not
have a significant impact on the financial position, results of operations, or
cash flows of the Company.

Item 3. Qualitative and Quantitative Disclosure About Market Risk

     Fair Value of Financial Instruments--The following disclosure of the
estimated fair value of financial instruments is made in accordance with the
requirements of Statement of Financial Accounting Standards No. 107,
"Disclosures about Fair Value of Financial Instruments". The estimated fair
values of financial instruments have been determined by the Company using
available market information and appropriate valuation methodologies.

     However, considerable judgment is required in interpreting market data to
develop the estimates of fair value. Accordingly, the estimates presented herein
are not necessarily indicative of the amounts that the Company could realize in
a current market exchange.

     The Company has not entered into, and does not expect to enter into,
financial instruments for trading or hedging purposes. The Company does not
currently anticipate entering into interest rate swaps and/or similar
instruments.

     The Company's carrying values of cash, marketable securities, accounts
receivable, accounts payable and accrued expenses are a reasonable approximation
of their fair value.

     The Company's business in this regard is subject to certain risks,
including, but not limited to, differing economic conditions, loss of
significant customers, changes in political climate, differing tax structures,
other regulations and restrictions and foreign exchange rate volatility. The
Company's future results could be materially and adversely impacted by changes
in these or other factors.
