CREDIT AGREEMENTS AND DEBT

At December 31, 1995, the Company had a domestic credit facility with two banks
providing for borrowings up to $50.0 million, reduced by the value of
outstanding letters of credit issued by the banks on behalf of the Company.

In May 1996, the Company entered into a five-year, unsecured $160.0 million
revolving credit facility with several banks.  This new facility, which
replaced the existing domestic credit facility, provides for borrowings and
issuances of letters of credit in multiple currencies.  Borrowings under the
new facility bear interest at various borrowing rates, including the prime rate
or 0.25% to 0.70% above the LIBOR rate.  A commitment fee of 0.10% to 0.225% on
the daily average unused portion of the facility is also assessed.  The maximum
borrowings available under the facility are reduced by the value of outstanding
letters of credit issued by the banks on behalf of the Company.  The letters of
credit issued by the banks under this agreement at June 30, 1996 totaled $30.9
million at June 30, 1996, including $28.3 million issued to support various
foreign subsidiary credit arrangements.  This new facility contains various
financial covenants.

In July 1996, approximately $93.7 million of $112.1 million in short-term
borrowings outstanding at June 30, 1996 were replaced with two unsecured term
loans, a $51.1 million loan maturing over five years and a $42.6 million loan
maturing over fifteen years.  The new term loans have been classified as part
of long-term debt at June 30, 1996.  The loans are denominated in Danish Kroner
and have adjustable interest rates based on market interest rates in Denmark.
The interest rates were initially established at 4.5% to 5.0%.  Interest
payments are required quarterly with principal payments beginning in the fourth
year the loans are outstanding.  These new loans contain various financial
covenant requirements.

INCOME TAX EXPENSE

The Company's income tax expense includes federal, foreign, and state
(including Puerto Rico) income taxes.  The estimated effective income tax rate
is based upon estimates for the full year for a number of variables including,
among other things, forecasted income in the United States and foreign
jurisdictions.  The effective tax rate could change as estimates of these and
other variables change throughout the year.

COMMITMENTS AND CONTINGENCIES

Contingent Liabilities

The Company periodically sells customer receivables and operating leases under
agreements which contain recourse provisions.  The Company could be obligated
to repurchase a portion of certain receivables and operating leases which were
sold in 1995 on a partial recourse basis, the terms of which allow the Company
to limit its risk of loss to approximately $7.8 million at June 30, 1996.  The
Company also has guarantees of $33.1 million outstanding at June 30, 1996
supporting bid and performance bonds to customers and others, of which $2.6
million were collateralized by letters of credit issued under the Company's
credit facility.  The Company believes it has adequate reserves for any
ultimate losses associated with these contingencies.

The Company, in management of its exposure to fluctuations in foreign currency
exchange rates, enters into forward foreign exchange contracts for both firm
commitments and anticipated transactions of sales and purchases which are
denominated in foreign currencies.  At June 30, 1996, the Company had forward
foreign exchange contracts of $51.7 million outstanding.

Litigation

On July 20, 1993, the Company filed suit against Advanced Fibre Communications
("AFC"), a California corporation; Quadrium Corporation ("Quadrium"), a
California corporation; and two individuals.  AFC filed various counterclaims
against the Company.  On June 24, 1996, the parties reached an agreement to
settle all claims.  As part of the settlement, the Company received $3 million
and 719,424 shares of AFC common stock at the end of June 1996.  In addition, in
late July 1996 AFC made an early payment of approximately $7.0 million
originally scheduled to be received over the next five years for the remaining
amounts due under the settlement. This amount will be recorded in the Company's
third quarter 1996 Consolidated Financial Statements, net of the applicable
expenses.

On April 10, 1995, the Company filed a lawsuit against Next Level
Communications ("NLC") and two former Company employees, alleging breach of
contract and the misuse of Company trade secrets.  The Company is seeking an
injunction prohibiting NLC and the former employees from continued use of
Company trade secrets and opportunities.  On March 28, 1996, the Company
received a favorable jury verdict in the amount of $369.2 million in damages.
On April 10, 1996, the court issued an injunction against NLC prohibiting the
transfer of the Company's trade secrets or disclosure of such trade secrets,
except in the ordinary course of business.  On June 11, 1996, the court entered
a judgement reducing the jury verdict in the Company's favor to $137.7 million.
The Company and NLC have both





                                     Page 8
<PAGE>   9
appealed the judgement and oral arguments are scheduled for September 1996.

On February 14, 1996, the Company joined Bell Atlantic in bringing an antitrust
action against AT&T Corporation ("AT&T") and Lucent Technologies, Inc.
("Lucent") alleging the use of monopoly power in the central office switch
market as part of a scheme to gain an unfair competitive advantage in the
remote digital terminal market.  The Company is seeking to compel AT&T and
Lucent to open up the interfaces to the central office switch so that any
manufacturer will have the ability to compete with applications, software,
features, and services, and will more rapidly deliver to its customers the
enhanced functionality that they have come to expect.  In July 1996, AT&T
brought a counterclaim against the Company alleging a "false advertising" claim
under the Lanham Act.

The Company is also party to other routine legal proceedings incidental to its
business.

The Company does not believe the ultimate resolution of the above litigation
will have a material adverse effect on its consolidated financial position.

COMMON STOCK

At the April 25, 1996 Annual Shareholders' Meeting, the shareholders approved
certain amendments to and an increase of 6 million shares of common stock
subject to the DSC Communications Corporation 1993 Employee Stock Option and
Securities Award Plan.

STOCK RIGHTS

On April 25, 1996, the Board of Directors declared a dividend of one preferred
stock purchase right on each outstanding share of the Company's common stock.
The dividend was paid on May 22, 1996 to shareholders of record on that date,
the same date the existing stock rights expired.  The rights become exercisable
only on the close of business ten days following a public announcement that a
person or group has acquired 15% or more of the outstanding shares of common
stock of the Company or a public announcement or commencement of a tender offer
or exchange offer which would result in the offeror's acquiring 15% or more of
the outstanding shares of common stock of the Company.  Once exercisable, each
right would entitle a holder to buy 1/1000 of a share of the Company's Series B
Junior Participating Preferred Stock at an exercise price of $175.00.  The
Company may redeem the rights, which expire on April 25, 2006, for $0.01 per
right prior to the rights becoming exercisable.

Item 2.  Management's Discussion and Analysis of Financial Condition
         and Results of Operations.

"SAFE HARBOR" STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM 
ACT OF 1995

With the exception of historical information, the matters discussed or
incorporated by reference in this Quarterly Report on Form 10-Q are
forward-looking statements that involve risks and uncertainties including, but
not limited to, economic conditions, product demand and industry capacity,
competitive products and pricing, manufacturing efficiencies, new product
development, ability to enforce patents, availability of raw materials and
critical manufacturing equipment, new plant startups, the regulatory and trade
environment, and other risks indicated in filings with the Securities and
Exchange Commission.

Results of Operations

For the three months ended June 30, 1996, the Company reported revenue of $356.4
million and net income of $21.3 million, or $0.18 per share, compared to revenue
of $360.0 million and net income of $52.0 million, or $0.44 per share, for the
three months ended June 30, 1995.  For the six months ended June 30, 1996, the
Company reported revenue of $664.3 million and net income of $32.8 million, or
$0.28 per share, compared to revenue of $678.0 million and net income of $93.9
million, or $0.80 per share, for the six months ended June 30, 1995.

Although the revenue level for the second quarter and first half of 1996 was
comparable to the same periods in 1995, the 1996 revenue amounts included a
higher volume of access product shipments and a lower level of switching
product revenue.  The product mix shift to lower gross margin content products
resulted in gross profit as a percentage of revenue declining  to  41% and 42%
for the second quarter and six months ended June 30, 1996, respectively,
compared to 49% and 50% in the same periods of 1995.  As experienced in the
1996 periods, the Company's gross margin percentage in future periods could
vary significantly due to changes in the relative mix of product deliveries and
software content.

Research and product development expense in the second quarter of 1996 was
$52.5 million, or 15% of revenue, compared to $47.9 million, or 13% of revenue,
in the second quarter of 1995.  Research and product development expense for
the first half of 1996 and 1995 was $105.6 million, or 16% of revenue, and
$94.9 million, or 14% of revenue, respectively.  The growth in research and
development expense reflects  the Company's on-going development of new
products and enhancements to existing products across all strategic product
lines.

Selling, general and administrative expense was $57.7 million and $113.5
million in the second quarter of 1996 and the six months ended June 30, 1996,
respectively, compared to $50.7 million and $96.8 million, respectively, for
the same periods of 1995.  As a percentage of revenue, selling, general and
administrative expense was 16% for the second quarter of 1996 and 17% for the
first half of 1996 as compared to 14% for both the second quarter and first six
months of 1995.  This expense growth resulted primarily from expanded
international selling activities and higher legal costs.  The Company is
actively pursuing claims related to its intellectual property rights and, as
this litigation progresses, legal expenses may continue to increase.  See
"Litigation" under "Commitment and Contingencies" in Notes to Condensed
Consolidated Financial Statements for further discussion.

DSC Communications A/S incurred an operating loss in the second quarter and
first half of 1996 due primarily to the delayed introduction of a new
generation of optical transmission equipment.  While initial deliveries of
certain new products began during the second quarter, future near-term
profitability of the Company's Denmark subsidiary is dependent upon the
successful completion and market acceptance of these products.

Interest expense has increased in the quarter and six month period ended June
30, 1996 compared to the same periods of 1995 due primarily to the $225 million
loan entered into in April 1995 which bears interest at 9%.  Interest expense
has also increased as a result of borrowings under several foreign subsidiary
borrowing arrangements entered into during the second half of 1995.

The Company's estimated effective income tax rate was 38% for the six month
period ended June 30, 1996 compared to 35% for the same period in 1995.  This
increase in the effective income tax rate is due primarily to the full
utilization of net operating loss and tax credit carryforwards in 1995 and an
expected increase in foreign taxes in 1996.  See "Income Tax Expense" in Notes
to Condensed Consolidated Financial Statements for further information.

The Company has certain forward exchange contracts which were entered into
based upon anticipated future business transactions.  Although these forward
contracts totaled only $5.3 million at June 30, 1996, future earnings could be
affected by the Company's practice of entering into these types of forwards as
forward contracts related to anticipated transactions are marked-to-market each
period.

The Company's future quarterly and annual operating results may be affected by
a number of factors, including the timing and ultimate receipt of orders from
certain customers which continue to constitute a large portion of the Company's
revenue; the successful enhancement





                                    Page 11
<PAGE>   12
of existing products; introduction and market acceptance of new products on a
timely basis; mix of products sold; product costs; manufacturing lead times;
significant fluctuations in foreign currency exchange rates; and changes in
general worldwide economic conditions, any of which could have an adverse
impact on operations.

Financial Condition and Liquidity

The Company's cash and cash equivalents at June 30, 1996 were $166.2 million
compared to $258.6 million at December 31, 1995, and marketable securities were
$296.4 million at June 30, 1996 compared to $310.7 million at December 31,
1995.

The Company used cash for operating activities of $23.6 million as  receivables
and inventories growth and a reduction of non-debt current liabilities
(including $48.2 million of domestic and foreign income tax payments) exceeded
earnings before depreciation and amortization.  Receivables were higher by
$33.1 million in 1996 which included long-term receivables growth of $22.9
million as the Company continued to offer financing alternatives to customers.
The $44.4 million growth in inventories is to support existing customer backlog
and expected additional customer requirements.

Investing activities during the six months ended June 30, 1996 included
additions to property and equipment of $68.2 million.  The Company's expected
future domestic and international business growth will require additional
capital expenditures.  The timing and extent of additional capital requirements
are dependent on future business growth.  However, the Company anticipates that
capital expenditures for 1996 could be in the range of approximately $150
million.

In April 1996, the Company made its first annual scheduled principal payment of
$28.1 million on the $225 million loan obtained during the second quarter of
1995.

In July 1996, the Company replaced approximately $93.7 million of the $112.1
million of the amounts outstanding at June 30, 1996 under short-term credit
agreements with two unsecured, long-term loans.  See "Credit Agreements and
Debt" in Notes to Condensed Consolidated Financial Statements for further
information.

As discussed in "Credit Agreements and Debt" in Notes to Condensed Consolidated
Financial Statements, the Company replaced its existing domestic credit facility
with a new, unsecured $160.0 million revolving credit agreement in early May
1996.  No borrowings were outstanding under this new credit facility at June 30,
1996.  Outstanding letters of credit, which totaled $30.9 million at June 30,
1996, reduce the amount of available borrowings.





                                    Page 12
<PAGE>   13
The Company is party to certain litigation, as disclosed in "Litigation" under
"Commitment and Contingencies" in Notes to Condensed Consolidated Financial
Statements, the outcome of which the Company believes will not have a material
adverse effect on its consolidated financial position.

The Company believes that its existing cash and marketable securities and
available credit facilities will be adequate to support the Company's financial
resource needs, including working capital requirements, capital expenditures,
operating lease obligations, and debt payments.  In order to be competitive in
the future, the Company believes that it will become increasingly necessary to
offer financing alternatives to both domestic and international customers.  To
the extent such financing becomes significant, additional borrowings could
become necessary.

         Puerto Rico, Inc., DSC Telecommunications Corporation, DSC Telecom,
         Inc., DSC Telecom L.P., and Sildor Investments B.V. (each a

    SUBORDINATION AGREEMENT issued by the Borrower and the Guarantors and dated
         July 23, 1996.

    Section 2.    PRINCIPAL AND INTEREST

2.01     PRINCIPAL.FOR VALUE RECEIVED and in order to refinance in part bridge
financing advances extended by certain of the Bank's branches in Denmark, the
Borrower promises to pay to the order of the Bank on August 1, 2011 (the "FINAL
MATURITY DATE"), the Principal Amount of this Note specified in Section 1 or,
if less, the aggregate unpaid principal amount of all loans (each a "LOAN")
made to the Borrower pursuant to the Loan Documents.

2.02     ADDITIONAL AMORTIZATION OF PRINCIPAL.  In addition to amounts payable
pursuant to Section 2.01, the Borrower promises to pay to the order of the Bank
on November 1, 1999, and on the first Business Day of each February, May,
August, and November thereafter through the first Business Day of May 2011, a
principal instalment of DKK 3,989,361.70.

2.03     INTEREST OPTIONS.The Borrower promises also to pay interest on the
unpaid principal amount of each Loan from the date thereof until paid at the
Stated Rate; or, if the Borrower shall so request with respect to a specific
Loan at least three Business Days before taking down or renewing that specific
Loan, at an Alternative Rate for the Interest Period requested in that same
request for drawing or renewal; provided that if the Interest Period of a Loan
on an Alternative Rate basis should mature without a specific timely request
having been received by the Bank to renew that Loan for a specific Interest
Period at an Alternative Rate available for such Interest Period, then interest
on such Loan shall be computed thereafter at the Stated Rate; further provided
that on and after maturity of this Note (whether by passage of time or by
Acceleration pursuant to
<PAGE>   2
PROMISSORY NOTE, P. 2


Section 6) or of any principal instalment or interest payment, such matured
amounts shall bear interest at a rate equal to the sum of 2% per annum and the
Stated Rate, payable on demand.

2.04     INTEREST COMPUTATION AND PAYMENT DATES.Interest shall be computed each
actual day elapsed on the basis of a 360 day year and shall be payable, in the
case of Loans with interest based on the Stated Rate, on the first Business Day
of each February, May, August, and November and, in the case of Loans with
interest based on an Alternative Rate, at the end of the respective Interest
Period as well as, in case of Loans with interest based on an Alternative Rate
and with Interest Periods in excess of three months, at each three month
anniversary of the commencement of the Interest Period; in addition, after
maturity of this Note (whether by passage of time or by Acceleration pursuant
to Section 6), interest shall be payable on demand.

The "STATED RATE" shall be a rate per annum equal to the sum of the Margin Over
Base Rate specified in Section 1 plus the Base Rate from time to time in
effect.  The term "BASE RATE" means the rate announced by the Bank from time to
time at its Holmens Kanal Branch, presently located at 2-12 Holmens Kanal,
DK-1092 Copenhagen K, Denmark, as its prime rate for domestic overdraft
facilities.  Each change in the prime rate shall result in a corresponding
change in the Base Rate and the Stated Rate and such change shall be effective
on the effective date of such change in the prime rate so announced by the
Bank.

An "ALTERNATIVE RATE" shall be either a "Cost of Funds Alternative Rate" or a
"Cibor Alternative Rate", depending on the request of the Borrower with respect
to a specific Loan for an Interest Period and any necessary agreement of the
Bank thereto.  A "COST OF FUNDS ALTERNATIVE RATE" for a specific Loan during an
Interest Period shall be a rate per annum equal to the sum of the Margin Over
Cost of Funds Rate specified in Section 1 plus the Cost of Funds Rate for the
Interest Period requested.  A "CIBOR ALTERNATIVE RATE" for a specific Loan
during an Interest Period shall be a rate per annum equal to the sum of the
Margin Over Cibor Rate specified in Section 1 plus the Cibor Rate for the
Interest Period requested.  Each such Alternative Rate and Interest Period will
be confirmed in writing by the Bank to the Borrower.  Each "INTEREST PERIOD"
requested by the Borrower shall be (a), if the Borrower shall have requested a
Cost of Funds Alternative Rate, of one, two, three, six, or twelve months or
such other period up to 10 years (or with the special consent of the Bank, up
to 15 years) as to which the Bank and the Borrower shall agree or (b), if the
Borrower shall have requested a Cibor Alternative Rate, of one, two, three, or
six months or such other period as to which the Bank and the Borrower shall
agree, and shall in either case commence on the day of takedown or renewal of
such Loan; provided, however, no Interest Period may be selected which would
extend beyond the Final Maturity Date of this Note or, taking into
consideration other Loans and Interest Periods previously established hereunder
as well as amortization payments due under Section 2.02 hereof, would otherwise
require a prepayment of a Loan prior to the end of the Interest Period
selected.  If any Interest Period shall end or other interest payment date fall
on a day which is not a Business Day, such Interest Period or interest payment
date shall be extended to the next succeeding Business Day unless such day
falls in another calendar month, in which case such Interest Period shall end
or interest payment date shall fall on the next preceding Business Day.  The
"COST OF FUNDS RATE" for any Loan shall mean the quotation offered two Business
Days prior to the commencement of such Interest Period in the Danish interbank
market to the Bank for Danish Krone deposits of amounts comparable to the
outstanding principal amount of the relevant Loan and with takedown and
maturities comparable to such Interest Period.  The "CIBOR RATE" for any Loan
shall mean the rate offered for deposits in Danish Kroner for the respective
Interest Period which appears on the Reuters Screen DKNH Page under the caption
"CIBOR Fixing" as of 11:00 a.m., Copenhagen time, two Copenhagen Business Days
prior to the commencement of such Interest Period; provided, however, if a rate
is not shown for the exact Interest Period selected by the Borrower, the higher
of the rates for the two closest interest periods will be selected; and further
provided, that if no relevant rates appear on such Reuter Screen, then the
Cibor Rate shall be the similarly defined rate shown on the relevant Telerate
Page and if no relevant rates appear on the Reuter and Telerate Pages, then the
Cibor rate shall be the quotation offered to the Bank two Copenhagen Business
Days prior to the commencement of such Interest Period in the interbank market
for deposits for the Interest Period selected and in the amount of the relevant
Loan.

PROMISSORY NOTE, P. 3



2.05     CERTAIN INTEREST RATE ADJUSTMENTS.In the event that the Bank shall
have determined (which determination shall, absent demonstrable error, be final
and conclusive and binding upon all parties) at any time, that:

(a) by reason of any change since the date of this Note in any applicable law
    or governmental rule, regulation, guideline, tax, impost or order (or any
    interpretation thereof and including the introduction of any new law or
    governmental rule, regulation, guideline, tax, impost or order) (such as,
    for example but not limited to, a change in official reserve requirements),
    the Cost of Funds Rate or the Cibor Rate, as the case may be, shall not
    represent the effective cost to such Bank for funding or maintaining any
    Cost of Funds Alternative Rate Loan or Cibor Alternative Rate Loan, as the
    case may be; or

(b) the making or continuance of any Loan based on an Alternative Rate has
    become unlawful or restricted by compliance by the Bank in good faith with
    any law, governmental rule, regulation, or guideline order, or an event has
    occurred after the date of this Note which in the good faith reasonable
    judgment of the Bank materially and adversely affects the Danish interbank
    market for Danish Kroner,

then the Borrower shall pay to the Bank, upon written demand therefor, such
additional amounts as shall be required to cause the Bank to receive interest
for the affected Loan at a rate per annum which shall equal the effective cost
to the Bank to make or maintain the Loan plus the Margin Over Cost of Funds
Rate or, as the case may be, Margin over Cibor Rate (a written notice as to
additional amounts owed the Bank, showing the basis for the calculation
thereof, submitted to the Borrower by the Bank shall, absent demonstrable
error, be final and conclusive and binding upon all of the parties hereto).

2.06     DEFINITION OF BUSINESS DAY.For the purposes of this note, a "BUSINESS
DAY" shall be a day on which banks shall be open for business in Copenhagen and
in New York City; provided, however, for the purposes of determining the date
for setting interest rates in Danish Kroner, a "BUSINESS DAY" shall be a day on
which banks shall be open for business in Copenhagen.

2.07     PLACE AND CURRENCY FOR PAYMENTS OF PRINCIPAL AND INTEREST.Each payment
by the Borrower pursuant to this Note shall be made without set-off or
counterclaim to the Bank at its Copenhagen Head Office for the account of the
Bank's Cayman Islands branch or such branch of the Bank as the Bank may direct.
Each such payment shall be made in lawful currency of Denmark and by transfer
in immediately available or same day funds.  Payments made other than by
transfer of immediately available funds a) shall not be given value in reducing
the obligations of the Borrower until such time, in the Bank's sole discretion,
as credit for said payment item in funds immediately available to the Bank is
received by the Bank in the clearing or collection process chosen, and b) are
credited subject to final collection and unconditional credit to, and accepted
by, the Bank.

2.08     WHEN LOANS MAY BE REPAID; COMPENSATION.Prior to the Final Maturity
Date of this Note, Loans may be repaid at the Borrower's option on the date at
least three days after the Borrower has given written notice to the Bank of its
intention to repay (or, if such date is not a Business Day, the first Business
Day thereafter); provided, however, as to Loans with interest based on an
Alternative Rate, said Loans shall not be repaid at the Borrower's option until
the end of the respective Interest Period applicable to the respective Loan.
If, however, any such Loans with interest based on an Alternative Rate are
repaid prior to the end of the respective Interest Period applicable to the
respective Loan, then Borrower shall compensate the Bank, on demand, for the
Bank's loss or expense in reemploying the funds repaid for the balance of the
applicable Interest Period.  A written notice as to additional amounts owed the
Bank, showing the basis for the calculation thereof, submitted to the Borrower
by the Bank shall, absent demonstrable error, be final and conclusive and
binding upon the parties hereto.
<PAGE>   4
PROMISSORY NOTE, P. 4



2.09     AVAILABILITY OF LOANS; REDUCTION OF AVAILABILITY; TRANSACTION
SIZE.Loans repaid may not be reborrowed; the aggregate of the principal amounts
of all outstanding Loans under this Note may at no time exceed the Principal
Amount of this Note.  Each takedown of principal hereof shall be in the minimum
amount of DKK 50,000,000.

On November 1, 1996, the Principal Amount of this Note shall be deemed to have
been reduced to the aggregate unpaid principal amount of all Loans hereunder and
no further Loans hereunder shall be permitted.

    Section 2.    PRINCIPAL AND INTEREST

2.01     PRINCIPAL.FOR VALUE RECEIVED and in order to refinance in part bridge
financing advances extended by certain of the Bank's branches in Denmark, the
Borrower promises to pay to the order of the Bank on August 1, 2001 (the "FINAL
MATURITY DATE"), the Principal Amount of this Note specified in Section 1 or,
if less, the aggregate unpaid principal amount of all loans (each a "LOAN")
made to the Borrower pursuant to the Loan Documents.

2.02     ADDITIONAL AMORTIZATION OF PRINCIPAL.  In addition to amounts payable
pursuant to Section 2.01, the Borrower promises to pay to the order of the Bank
on August 1, 2000, a principal instalment of DKK 150,000,000.00.

2.03     INTEREST OPTIONS.The Borrower promises also to pay interest on the
unpaid principal amount of each Loan from the date thereof until paid at the
Stated Rate; or, if the Borrower shall so request with respect to a specific
Loan at least three Business Days before taking down or renewing that specific
Loan, at an Alternative Rate for the Interest Period requested in that same
request for drawing or renewal; provided that if the Interest Period of a Loan
on an Alternative Rate basis should mature without a specific timely request
having been received by the Bank to renew that Loan for a specific Interest
Period at an Alternative Rate available for such Interest Period, then interest
on such Loan shall be computed thereafter at the Stated Rate; further provided
that on and after maturity of this Note (whether by passage of time or by
Acceleration pursuant to





<PAGE>   2
PROMISSORY NOTE, P. 2


Section 6) or of any principal instalment or interest payment, such matured
amounts shall bear interest at a rate equal to the sum of 2% per annum and the
Stated Rate, payable on demand.

2.04     INTEREST COMPUTATION AND PAYMENT DATES.Interest shall be computed each
actual day elapsed on the basis of a 360 day year and shall be payable, in the
case of Loans with interest based on the Stated Rate, on the first Business Day
of each February, May, August, and November and, in the case of Loans with
interest based on an Alternative Rate, at the end of the respective Interest
Period as well as, in case of Loans with interest based on an Alternative Rate
and with Interest Periods in excess of three months, at each three month
anniversary of the commencement of the Interest Period; in addition, after
maturity of this Note (whether by passage of time or by Acceleration pursuant
to Section 6), interest shall be payable on demand.

The "STATED RATE" shall be a rate per annum equal to the sum of the Margin Over
Base Rate specified in Section 1 plus the Base Rate from time to time in
effect.  The term "BASE RATE" means the rate announced by the Bank from time to
time at its Holmens Kanal Branch, presently located at 2-12 Holmens Kanal,
DK-1092 Copenhagen K, Denmark, as its prime rate for domestic overdraft
facilities.  Each change in the prime rate shall result in a corresponding
change in the Base Rate and the Stated Rate and such change shall be effective
on the effective date of such change in the prime rate so announced by the
Bank.

An "ALTERNATIVE RATE" shall be either a "Cost of Funds Alternative Rate" or a
"Cibor Alternative Rate", depending on the request of the Borrower with respect
to a specific Loan for an Interest Period and any necessary agreement of the
Bank thereto.  A "COST OF FUNDS ALTERNATIVE RATE" for a specific Loan during an
Interest Period shall be a rate per annum equal to the sum of the Margin Over
Cost of Funds Rate specified in Section 1 plus the Cost of Funds Rate for the
Interest Period requested.  A "CIBOR ALTERNATIVE RATE" for a specific Loan
during an Interest Period shall be a rate per annum equal to the sum of the
Margin Over Cibor Rate specified in Section 1 plus the Cibor Rate for the
Interest Period requested.  Each such Alternative Rate and Interest Period will
be confirmed in writing by the Bank to the Borrower.  Each "INTEREST PERIOD"
requested by the Borrower shall be (a), if the Borrower shall have requested a
Cost of Funds Alternative Rate, of one, two, three, six, or twelve months or
such other period up to five years as to which the Bank and the Borrower shall
agree or (b), if the Borrower shall have requested a Cibor Alternative Rate, of
one, two, three, or six months or such other period as to which the Bank and
the Borrower shall agree, and shall in either case commence on the day of
takedown or renewal of such Loan; provided, however, no Interest Period may be
selected which would extend beyond the Final Maturity Date of this Note or,
taking into consideration other Loans and Interest Periods previously
established hereunder as well as amortization payments due under Section 2.02
hereof, would otherwise require a prepayment of a Loan prior to the end of the
Interest Period selected.  If any Interest Period shall end or other interest
payment date fall on a day which is not a Business Day, such Interest Period or
interest payment date shall be extended to the next succeeding Business Day
unless such day falls in another calendar month, in which case such Interest
Period shall end or interest payment date shall fall on the next preceding
Business Day.  The "COST OF FUNDS RATE" for any Loan shall mean the quotation
offered two Business Days prior to the commencement of such Interest Period in
the Danish interbank market to the Bank for Danish Krone deposits of amounts
comparable to the outstanding principal amount of the relevant Loan and with
takedown and maturities comparable to such Interest Period.  The "CIBOR RATE"
for any Loan shall mean the rate offered for deposits in Danish Kroner for the
respective Interest Period which appears on the Reuters Screen DKNH Page under
the caption "CIBOR Fixing" as of 11:00 a.m., Copenhagen time, two Copenhagen
Business Days prior to the commencement of such Interest Period; provided,
however, if a rate is not shown for the exact Interest Period selected by the
Borrower, the higher of the rates for the two closest interest periods will be
selected; and further provided, that if no relevant rates appear on such Reuter
Screen, then the Cibor Rate shall be the similarly defined rate shown on the
relevant Telerate Page and if no relevant rates appear on the Reuter and
Telerate Pages, then the Cibor rate shall be the quotation offered to the Bank
two Copenhagen Business Days prior to the commencement of such Interest Period
in the interbank market for deposits for the Interest Period selected and in
the amount of the relevant Loan.

PROMISSORY NOTE, P. 3


2.05     CERTAIN INTEREST RATE ADJUSTMENTS.In the event that the Bank shall
have determined (which determination shall, absent demonstrable error, be final
and conclusive and binding upon all parties) at any time, that:

(a) by reason of any change since the date of this Note in any applicable law
    or governmental rule, regulation, guideline, tax, impost or order (or any
    interpretation thereof and including the introduction of any new law or
    governmental rule, regulation, guideline, tax, impost or order) (such as,
    for example but not limited to, a change in official reserve requirements),
    the Cost of Funds Rate or the Cibor Rate, as the case may be, shall not
    represent the effective cost to such Bank for funding or maintaining any
    Cost of Funds Alternative Rate Loan or Cibor Alternative Rate Loan, as the
    case may be; or

(b) the making or continuance of any Loan based on an Alternative Rate has
    become unlawful or restricted by compliance by the Bank in good faith with
    any law, governmental rule, regulation, or guideline order, or an event has
    occurred after the date of this Note which in the good faith reasonable
    judgment of the Bank materially and adversely affects the Danish interbank
    market for Danish Kroner,

then the Borrower shall pay to the Bank, upon written demand therefor, such
additional amounts as shall be required to cause the Bank to receive interest
for the affected Loan at a rate per annum which shall equal the effective cost
to the Bank to make or maintain the Loan plus the Margin Over Cost of Funds
Rate or, as the case may be, Margin over Cibor Rate (a written notice as to
additional amounts owed the Bank, showing the basis for the calculation
thereof, submitted to the Borrower by the Bank shall, absent demonstrable
error, be final and conclusive and binding upon all of the parties hereto).

2.06     DEFINITION OF BUSINESS DAY.For the purposes of this note, a "BUSINESS
DAY" shall be a day on which banks shall be open for business in Copenhagen and
in New York City; provided, however, for the purposes of determining the date
for setting interest rates in Danish Kroner, a "BUSINESS DAY" shall be a day on
which banks shall be open for business in Copenhagen.

2.07     PLACE AND CURRENCY FOR PAYMENTS OF PRINCIPAL AND INTEREST.Each payment
by the Borrower pursuant to this Note shall be made without set-off or
counterclaim to the Bank at its Copenhagen Head Office for the account of the
Bank's Cayman Islands branch or such branch of the Bank as the Bank may direct.
Each such payment shall be made in lawful currency of Denmark and by transfer
in immediately available or same day funds.  Payments made other than by
transfer of immediately available funds a) shall not be given value in reducing
the obligations of the Borrower until such time, in the Bank's sole discretion,
as credit for said payment item in funds immediately available to the Bank is
received by the Bank in the clearing or collection process chosen, and b) are
credited subject to final collection and unconditional credit to, and accepted
by, the Bank.

2.08     WHEN LOANS MAY BE REPAID; COMPENSATION.Prior to the Final Maturity
Date of this Note, Loans may be repaid at the Borrower's option on the date at
least three days after the Borrower has given written notice to the Bank of its
intention to repay (or, if such date is not a Business Day, the first Business
Day thereafter); provided, however, as to Loans with interest based on an
Alternative Rate, said Loans shall not be repaid at the Borrower's option until
the end of the respective Interest Period applicable to the respective Loan.
If, however, any such Loans with interest based on an Alternative Rate are
repaid prior to the end of the respective Interest Period applicable to the
respective Loan, then Borrower shall compensate the Bank, on demand, for the
Bank's loss or expense in reemploying the funds repaid for the balance of the
applicable Interest Period.  A written notice as to additional amounts owed the
Bank, showing the basis for the calculation thereof, submitted to the Borrower
by the Bank shall, absent demonstrable error, be final and conclusive and
binding upon the parties hereto.

all interest and fees as may be owed under such facilities, lines, loans,
transactions or other liabilities
<PAGE>   2
GUARANTY, PAGE 2/5



thereunder and all expense or other liability (including reasonable attorney's
fees) incurred by the Bank in enforcing any of such liabilities and/or the
terms hereof.  The undersigned waive notice of acceptance of this guaranty and
of any liability to which it applies or may apply under the terms hereof, and
waive presentment, demand of payment, notice of dishonor or non-payment,
protest, notice of protest on any such liabilities, suit or taking other action
by the Bank against, and giving any notice of default or other notice to, or
making any demand on, any party liable thereon (including the undersigned).
Payment by the undersigned is in all cases to be made at the office of the
Bank's New York branch, presently located at 280 Park Avenue, New York City, NY
10017, or at such other office of the Bank as the Bank may direct, in funds
immediately available to the Bank in the currency in which the respective
liability is denominated.

The Bank may, at any time and from time to time (whether or not after
revocation or termination of this guaranty) without the consent of or notice to
the undersigned, except such notice as may be required by applicable statute
and cannot be waived, without incurring responsibility to the undersigned,
without impairing or releasing the obligations of the undersigned hereunder,
upon or without any terms or conditions and in whole or in part, (1) change the
manner, place or terms of payment and/or change or extend the time of payment
of, renew, or alter any liability of the Borrower hereby guaranteed, or any
liabilities (including any of those hereunder) incurred directly or indirectly
in respect thereof or hereof, and the guaranty herein made shall apply to the
liabilities of the Borrower, changed, extended, renewed, or altered in any
manner, (2) sell, exchange, release, surrender, realize upon or otherwise deal
with in any manner and in any order any property by whomsoever at any time
pledged or mortgaged to secure or howsoever securing the liabilities hereby
guaranteed or any liabilities (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof and/or any offset
thereagainst, (3) exercise or refrain from exercising any rights against the
Borrower or others (including the undersigned) or otherwise act or refrain from
acting, (4) settle or compromise any liabilities hereby guaranteed and/or any
liabilities (including any of those hereunder) incurred directly or indirectly
in respect thereof or hereof, and may subordinate the payment of all or any
part thereof to the payment of any liabilities which may be due to the Bank or
others, (5) apply any sums by whomsoever paid or howsoever realized to any
liability or liabilities of the Borrower to the Bank regardless of what
liability or liabilities of the Borrower to the Bank remain unpaid.

No invalidity, irregularity or unenforceability of the liabilities hereby
guaranteed shall affect, impair, or be a defense to this guaranty.  This
guaranty is a primary, direct, immediate, and absolute obligation of the
undersigned to the Bank, and the Bank shall not be required to pursue any
remedies it may have against the Borrower or any other person before exercising
its rights hereunder.

This guaranty is a continuing one and all liabilities to which it applies or
may apply under the terms hereof shall be conclusively presumed to have been
created in reliance hereon.  As to each of the undersigned, this guaranty shall
continue until written notice of revocation signed by such undersigned or until
written notice of the death of such undersigned shall in each case have been
actually received by the Bank, notwithstanding a revocation by, or the death
of, or complete or partial release for any cause of, any one or more of the
remainder of the undersigned, or of the Borrower or of anyone liable in any
manner for the liabilities hereby guaranteed or for liabilities (including
those hereunder) incurred directly or indirectly in respect thereof or hereof,
and notwithstanding the dissolution, termination, or increase, decrease or
change in personnel of any one or more of the undersigned which may be
partnerships.  No revocation or termination hereof shall affect in any manner
rights arising under this guaranty with respect to liabilities arising prior to
receipt by the Bank of written notice of such revocation or termination and the
sole effect of revocation or termination hereof shall be to exclude from this
guaranty liabilities thereafter arising which are unconnected with liabilities
theretofore arising or transactions theretofore entered into.

In the event that the Borrower is a partnership, this guaranty shall continue
in effect and apply to all liabilities of the Borrower and/or any successor
partnership(s) from time to time contracted, assumed, incurred, or
<PAGE>   3
GUARANTY, PAGE 3/5



accruing before or after any dissolution, termination or changes in personnel
of the Borrower and/or any successor partnership(s).

Demands on, or any notices to, the undersigned may be made or given by the Bank
by leaving same at the address given below or the last known address of the
undersigned or by mailing, telegraphing, cabling or telecopying same to either
such address, with the same effect as if delivered to the undersigned in
person.

No delay on the part of the Bank in exercising any of its rights (including
those hereunder) and no partial or single exercise thereof and no action or
non-action by the Bank, with or without notice to the undersigned or anyone
else, shall constitute a waiver of any rights or shall affect or impair this
guaranty.

Any and all rights and claims of the undersigned against the Borrower or any
property of the Borrower arising by reason of any payment by the undersigned to
the Bank pursuant to this guaranty, shall be subject and subordinate in right
of payment to the prior payment in full of all liabilities of the Borrower to
the Bank.

This guaranty shall inure to the benefit of the successors and assigns of the
Bank who shall have, to the extent of their interest, the rights of the Bank
hereunder; provided, however, that the rights of the Bank hereunder, if any be
retained by it, shall have priority over and be senior to the rights of its
successors and assigns unless the Bank shall otherwise elect.  This guaranty is
binding upon the undersigned and the estates, executors, administrators,
personal representatives, heirs, successors and assigns of the undersigned.

The undersigned agree(s) that this guaranty shall continue to be effective or
shall be reinstated, as the case may be, if all or any part of any payment of
principal of or interest on any of the obligations hereby guaranteed is at any
time avoided or rescinded or must otherwise be restored or repaid by the Bank
as a result of the bankruptcy of the Borrower, or otherwise, all as though such
payment had not been made.

The undersigned, if more than one, shall be jointly and severally liable
hereunder and the term "undersigned" shall mean the undersigned or any one or
more of them; provided, however, as to any of the undersigned as is not a
direct or indirect majority shareholder of the Borrower on the date of this
guaranty, the liability of such undersigned shall be limited to the maximum
amount of such liability as may be incurred by such undersigned without
rendering the obligation of such undersigned under this guaranty voidable under
applicable law relating to insolvency, fraudulent conveyance or fraudulent
transfer.

Anyone signing this guaranty shall be bound hereby, whether or not anyone else
signs this guaranty at any time.  The term "Bank" or "the Bank" includes any
agent of the Bank acting for it.

THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE BANK AND OF THE UNDERSIGNED
HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE
STATE OF NEW YORK.

EACH OF THE UNDERSIGNED AGREES THAT ANY LEGAL ACTION OR PROCEEDING WITH RESPECT

REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT ITS ADDRESS SPECIFIED

NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE BANK TO SERVE PROCESS IN ANY OTHER
MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE TO
PROCEED AGAINST ANY OF THE UNDERSIGNED OR THE PROPERTY OF ANY OF THE
UNDERSIGNED IN ANY OTHER JURISDICTION.

         WHEREAS, DSC Communications Corporation is the parent of and a
supplier to Obligor and the other Subordinated Creditors are sister companies
to and suppliers to Obligor, and together the Subordinated Creditors request
DEN DANSKE BANK Aktieselskab (herein the "BANK") to refinance certain existing

         WHEREAS, the Bank is willing to make those Term Loans to the Obligor
substantially according to the terms of certain credit documents including

subordination;

         NOW, THEREFORE, in consideration for the Bank's extension of credit

follows:
<PAGE>   2
Subordination Agreement with DSC Communications A/S as Obligor            page 2


         1.      All accounts payable, indebtedness, obligations, and
liabilities of the Obligor to each of the Subordinated Creditors individually
and to some or all of the Subordinated Creditors in the aggregate, including
principal and interest, whether direct or indirect, absolute or contingent,
secured or unsecured, due or to become due, now existing or hereafter arising
and howsoever evidenced, together with any renewal or renewals, extension or
extensions thereof, in whole or in part (the "SUBORDINATED DEBT"), shall be
subordinated and junior in right of payment, and the same hereby are
subordinated and made junior in right of payment to any and all indebtedness,
obligations and liabilities of the Obligor to the Bank pursuant to the Notes,
whether now existing or hereafter arising, including principal and interest,
whether direct or indirect, absolute or contingent, secured or unsecured, due
or to become due, and howsoever evidenced, together with any renewal or
renewals, extension or extensions thereof, in whole or in part, and all
post-petition interest in respect of the foregoing (the "SUPERIOR DEBT").

         2.      The Subordinated Creditors will not ask, demand, sue for, take
or receive from the Obligor, by way of setoff or in any other manner, all or
any part of the Subordinated Debt, and the Subordinated Creditors hereby waive
any right of offset with respect to the Subordinated Debt.

         3.      In the event that the Obligor becomes insolvent or bankrupt or
makes an assignment for the benefit of creditors or any proceedings shall be
commenced involving dissolution, insolvency, liquidation or adjustment of the
indebtedness of the Obligor, the Bank shall be entitled to receive for
application upon the Superior Debt (until payment in full of such Superior
Debt) any payment or distribution of any kind whatsoever which may be payable
or deliverable in such proceedings with respect to the Subordinated Debt.

         4.      As to each payment or distribution received by any
Subordinated Creditor upon or with respect to the Subordinated Debt prior to
the satisfaction in full of the Superior Debt, each Subordinated Creditor
receiving such payment or distribution for itself or for any other Subordinated
Creditor shall forthwith deliver the same to the Bank in the form received
(except for endorsement or assignment by said Subordinated Creditor(s) where
required by the Bank), for application on the Superior Debt, and, until so
delivered, the same shall be held in trust by said Subordinated Creditor(s) as
the property of the Bank.  In the event of failure of any of the Subordinated
Creditors to make any such endorsement or assignment, the Bank, or any of its
officers or employees on behalf of the Bank, is hereby unequivocally authorized
to make the same.  Each such payment or distribution is in all cases to be
delivered to the Bank's New York branch, presently located at 280 Park Avenue,
New York NY 10017, or to such other office of the Bank as the Bank may direct.

         5.      Notwithstanding anything to the contrary set forth in
paragraphs 1,2,3 or 4 above, if no Acceleration (as such term is defined in the
Notes) under the Notes and no Event of Default under the Notes (as such is
defined in the Notes, an "EVENT OF DEFAULT") or event, act or condition which
with notice or lapse of time or both would constitute an Event of Default (a
"DEFAULT") has occurred and no Event of Default or Default would occur
<PAGE>   3
Subordination Agreement with DSC Communications A/S as Obligor            page 3


as a result of any payment described in this paragraph 5, the Obligor may pay
and the Subordinated Creditors may retain payments made with respect to all
accounts now or in the future payable to the Subordinated Creditors

         6.      The Subordinated Creditors, without the written consent of the
Bank, shall not assign, transfer, hypothecate or dispose of the Subordinated
Debt or any part thereof while any Superior Debt remains unpaid.

         7.      This Agreement shall constitute a continuing agreement of
subordination which shall remain in effect until the credit provided for under
the Notes (including any renewals, extensions or amendments thereof) and all
other commitments, contingent or otherwise, of the Bank with respect to any
loans or other indebtedness that would constitute Superior Debt have expired or
been terminated and the Superior Debt has been fully paid and satisfied.

         8.      At any time and from time to time, the Bank may (a) enter into
such agreement or agreements with the Obligor as the Bank may deem proper
extending the time of payment or renewing or otherwise altering the terms of
all or any part of the Superior Debt, or (b) exchange, sell or surrender or
otherwise deal with any security, mortgage, pledge or collateral or (c) release
any balance of funds of the Obligor on deposit with the Bank or (d) extend
other credit facilities to Obligor or permit to exist other debt of the Obligor
to the Bank which other facilities or debt are not Superior Debt ("OTHER
DEBT"), or (e) apply any payments from the Obligor to the payment of such Other
Debt, any or all of which may be done without notice to the Obligor or the
Subordinated Creditors and without in any way impairing or affecting this
Agreement or reducing the obligations of the Subordinated Creditors to the Bank
hereunder with respect to the Superior Debt.  Presentment, demand, protest and
notice of protest or dishonor, and diligence in collecting any of the Superior
Debt are each hereby waived.

         9.      No waiver shall be deemed to be made by the Bank of any of its
rights hereunder unless the same shall be waived in a writing signed by the
Bank, and each such waiver, if any, shall be a waiver only with respect to the
specific matters to which the waiver relates and shall in no way impair the
rights of the Bank or the obligations of the Subordinated Creditors to the Bank
in any other respect at any time.

         10.     The possession by the Bank of the Notes or other evidence of
indebtedness of the Obligor made or endorsed by the Obligor in replacement,
renewal, amendment, or extension of the Notes, unless direct written evidence
to the contrary is produced, shall be conclusive that it is a part of the
Superior Debt covered by the Guaranty and that full value was given by the Bank
therefor.

         11.     Notice of acceptance by the Bank of this Agreement is hereby
waived by the Subordinated Creditors and the Obligor.  This Agreement may not
be modified or terminated without the consent of the Bank.
<PAGE>   4
Subordination Agreement with DSC Communications A/S as Obligor            page 4


         12.     This Agreement shall bind and inure to the benefit of the
Obligor, the Subordinated Creditors and the Bank and their respective
successors and assigns.

         13.     The Subordinated Creditors agree that no payment or
distribution by it directly to the holders of the Superior Debt pursuant to the
conditions of this Agreement shall entitle the Subordinated Creditors to any
rights of subrogation in respect thereof until all Superior Debt shall have
been paid in full in accordance with respective terms thereof.

         14.     THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE OBLIGOR,
THE SUBORDINATED CREDITORS, AND OF THE BANK HEREUNDER SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

PROCEEDING WITH RESPECT TO THIS AGREEMENT, OR ANY AGREEMENT, INSTRUMENT, OR
DOCUMENT ENTERED INTO IN FURTHERANCE HEREOF MAY BE BROUGHT IN THE COURTS OF THE
STATE OF NEW YORK LOCATED IN NEW YORK COUNTY OR OF THE UNITED STATES OF AMERICA

GUARANTY, EACH OF THE UNDERSIGNED HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF
ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID
COURTS.  EACH OF THE UNDERSIGNED HEREBY IRREVOCABLY WAIVES TRIAL BY JURY AND
ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION BASED ON THE
GROUNDS OF FORUM NON CONVENIENS WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.
EACH OF THE UNDERSIGNED HEREBY AGREES THAT SERVICE OF PROCESS IN ANY SUCH
ACTION OR PROCEEDING MAY BE MADE BY THE MAILING OF COPIES OF SUCH PROCESS BY
REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT ITS ADDRESS SPECIFIED
BELOW OR TO ANY OTHER ADDRESS OF WHICH IT SHALL HAVE GIVEN NOTICE TO THE BANK.
NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE BANK TO SERVE PROCESS IN ANY OTHER
MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE TO
PROCEED AGAINST ANY OF THE UNDERSIGNED OR THE PROPERTY OF ANY OF THE
UNDERSIGNED IN ANY OTHER JURISDICTION.
