Item 1.  Financial Statements


The condensed  consolidated  interim financial  statements  included herein have
been  prepared by Integrated  Systems,  Inc.  ("the  Company"),  without  audit,
pursuant to the rules and regulations of the Securities and Exchange Commission.
Although  certain  information  and footnote  disclosures  normally  included in
financial  statements  prepared in accordance with generally accepted accounting
principles   have  been  condensed  or  omitted   pursuant  to  such  rules  and
regulations, the Company believes that the disclosures made are adequate to make
the  information  presented not  misleading.  It is suggested that the condensed
consolidated  interim  financial  statements  be read in  conjunction  with  the
consolidated  financial  statements  and  the  notes  thereto  included  in  the
Company's  Annual Report on Form 10-K for the year ended  February 28, 1997. The
February 28, 1997 condensed consolidated balance sheet data was derived from the
audited financial  statements,  but does not include all disclosures required by
generally accepted accounting principles.

The accompanying  condensed  consolidated interim financial statements have been
prepared in all material respects in conformity with the standards of accounting
measurements set forth in Accounting Principles Board Opinion No. 28 and, in the
opinion  of  management,  reflect  all  adjustments,  consisting  only of normal
recurring  adjustments,  necessary to summarize  fairly the financial  position,
results of operations,  and cash flows for the periods indicated. The results of
operations for the interim periods  presented are not necessarily  indicative of
the results to be expected for the full year.

                          INTEGRATED SYSTEMS, INC.
            NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

           (Information for the three and six months ended August 31,
                           1997 and 1996 is unaudited)

1.       Summary of Significant Accounting Policies

The  condensed   consolidated  financial  statements  include  the  accounts  of
Integrated Systems, Inc. and its wholly owned subsidiaries, after elimination of
all significant  intercompany  accounts and transactions,  and should be read in
conjunction  with the  Company's  Annual  Report on Form 10-K for the year ended
February 28, 1997.  These  condensed  consolidated  financial  statements do not
include all  disclosures  normally  required by  generally  accepted  accounting
principles.

2.       Earnings Per Share

Earnings per share is computed  using the weighted  average number of common and
common equivalent shares outstanding during the period. Common equivalent shares
result  from the assumed  exercise  of  outstanding  stock  options  that have a
dilutive effect when applying the treasury stock method.


The  following  table  sets  forth the  calculation  of  earnings  per share for
purposes of this report:

Fully diluted earnings per share, for all periods presented, were not materially
different from the amounts shown above.

3.       Contingencies

In January  1997, a former  employee  filed a complaint  against the Company and
certain of its officers,  alleging  claims for,  among other  things,  breach of
contract,  fraud,  negligent  misrepresentation  and labor code violations.  The
complaint  seeks general and specific  damages of no less than $1.5 million plus
exemplary  damages,  attorney's  fees and costs of suit.  The  Company has filed
answers to the complaint  denying all of the allegations  and asserting  various
affirmative  defenses.  The Company believes it has meritorious  defenses to the
claims and intends to defend the suit vigorously.

In fiscal 1997, a distributor for the Company's sales and service  subsidiary in
Paris,  France  filed a complaint  against  the  subsidiary  alleging  breach of
contract.  The complaint seeks damages of approximately  $850,000.  An answer to
the complaint has been filed denying the  allegations.  The Company  believes it
has meritorious defenses to the claim and intends to defend the suit vigorously.

The  Company is  involved  in a contract  dispute  with a  customer.  Management
believes it has meritorious defenses in relation to this dispute.

The litigation and dispute are subject to inherent uncertainties and thus, there
can be no assurance that the litigation or dispute will be resolved favorably to
the  Company  or that  they  will  not have a  material  adverse  effect  on the
Company's financial position or results of operations.

The Company is subject to various  other legal  proceedings  and claims,  either
asserted or unasserted,  which arise in the ordinary  course of business.  While
management  does not believe  that the outcome of any of the legal  matters will
have a material adverse effect on the Company's consolidated financial position,
there can be no assurance  that these matters will be resolved  favorably to the
Company.

4.       Recent Accounting Pronouncements

In February 1997, the Financial  Accounting  Standards Board issued Statement of
Financial Accounting  Standards No. 128 ("SFAS No. 128"),  "Earnings per Share,"
which specifies the computation,  presentation  and disclosure  requirements for
earnings per share. SFAS No. 128 supersedes  Accounting Principles Board Opinion
No. 15, is effective for financial  statements  issued for periods  ending after
December 15, 1997, and requires that prior periods be restated.

In June 1997,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial   Accounting   Standards   No.  130  ("SFAS  No.   130"),   "Reporting
Comprehensive  Income," which establishes  standards of disclosure and financial
statement  presentation for reporting total  comprehensive  income in individual
components.  SFAS No, 130 is effective for fiscal years beginning after December
15, 1997, and will require earlier periods to be restated to reflect application
of the provisions of SFAS No. 130.

In June 1997,  the  Financial  Accounting  Standard  Board  issued  Statement of
Financial  Accounting  Standards  No. 131 ("SFAS No. 131"),  "Disclosures  About
Segments of an Enterprise and Related  Information," which specifies  disclosure
requirements for segment reporting.  The above statements supersedes SFAS No. 14
and SFAS No. 18 and is effective for fiscal years  beginning  after December 15,
1997, and requires earlier years to be restated if practicable.

The impact of the adoption of the above  statements on the financial  statements
of the Company has not yet been determined.

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

The  following  information  should be read in  conjunction  with the  condensed
consolidated interim financial statements and the notes thereto included in Item
1 of this  Quarterly  Report and with  Management's  Discussion  and Analysis of
Financial Condition and Results of Operations  contained in the Company's Annual
Report on Form 10-K for the year  ended  February  28,  1997,  as filed with the
Securities and Exchange Commission on May 29, 1997.

Overview

Integrated Systems, Inc. ("the Company") designs, develops, markets and supports
software  products and provides  related  engineering  services  principally for
embedded  microprocessor-based   applications.  The  Company  currently  derives
substantially  all of its revenues from  licensing  these products and providing
related maintenance and engineering and consulting  services.  In July 1996, the
Company acquired  Epilogue  Technology  Corporation  ("Epilogue"),  a New Mexico
corporation  in the  business of  developing  network  management  and  embedded
Internet  software  for  telecommunications  and data  communications  equipment
manufacturers,  embedded software  suppliers and networking  related  integrated
circuit  manufacturers.  The  combination  was  accounted  for as a  pooling  of
interests.  The results of operations for Epilogue have been included only since
the date of acquisition,  as previous results were not significant.  In November
1996, the Company amended the terms of the acquisition of Diab Data, Inc. ("Diab
Data") which was  acquired in fiscal year 1996 in a  transaction  accounted  for
under  the  equity  method of  accounting.  Revising  the terms of the  original
acquisition  agreement  requires the Company to consolidate  the results of Diab
Data from the fourth quarter of fiscal year 1997 forward.

Forward-Looking Information is Subject to Risk and Uncertainty; Additional Risks
and Uncertainties

Except for the historical  information  contained in this Quarterly Report,  the
matters herein contain "forward-looking"  statements and information (as defined
in the Private  Securities  Litigation Reform Act of 1995) that involve risk and
uncertainty.  These forward-looking  statements include, but are not limited to,
the Company's  liquidity and capital needs and various business  environment and
trend  information.  Actual  future  results  and trends  may differ  materially
depending  on a variety of  factors,  including  the volume and timing of orders
received  during the quarter,  the mix of and changes in  distribution  channels
through which the Company's  products are sold, the timing and acceptance of new
products and product enhancements by the Company or its competitors,  changes in
pricing,  buyouts of run-time  licenses,  product life cycles,  the level of the
Company's sales of third party products, purchasing patterns of distributors and
customers, competitive conditions in the industry, business cycles affecting the
markets in which the Company's products are sold,  extraordinary events, such as
litigation or acquisitions,  including related charges,  and economic conditions
generally  or in various  geographic  areas.  All of the  foregoing  factors are
difficult to forecast. The future operating results of the Company may fluctuate
as a result of these and the other risk factors detailed in the Company's Annual
Report on Form 10-K for the year ended  February 28, 1997,  and other  documents
filed by the Company with the Securities and Exchange Commission.

Due to all of the foregoing factors, the Company believes that  period-to-period
comparisons  of its results of operations  are not  necessarily  meaningful  and
should not be relied upon as an  indication  of future  performance.  During the
previous  fiscal year,  the  Company's  actual  performance  did not meet market
expectations.  It is  likely  that,  in  some  future  quarters,  the  Company's
operating  results will be below the  expectations  of stock market analysts and
investors.  Consequently,  the purchase or holding of the Company's Common Stock
involves an extremely high degree of risk.

Revenue

The Company's total revenue increased 23% to $32.2 million in the second quarter
of fiscal year 1998 from $26.1 million in the second quarter of fiscal year 1997
and 15% to $56.8  million in the first six months of fiscal year 1998 from $49.3
million in the first six months of fiscal year 1997.  Product revenue  increased
marginally to $17.2 million in the second quarter of fiscal year 1998 from $17.1
million in the second  quarter of fiscal year 1997,  and 4% to $32.2  million in
the first six  months of fiscal  year 1998 from  $30.8  million in the first six
months of fiscal  year  1997.  The  dollar  increases  in  product  revenue  are
primarily due to the inclusion of product revenue from Diab Data and Epilogue in
fiscal year 1998, plus increased unit shipments of SNiFF+(TM).  Services revenue
increased  67% to $15.0  million in the second  quarter of fiscal year 1998 from
$9.0 million in the second quarter of fiscal year 1997, and 33% to $24.6 million
in the first six months of fiscal year 1998 from $18.4  million in the first six
months of fiscal year 1997.  These  dollar  increases  are the result of both an
increase in maintenance revenue from a growing installed base of customers,  and
from an increase in  engineering  services and  consulting  activities at Doctor
Design, Inc. ("Doctor Design"), an engineering services subsidiary  specializing
in multimedia  hardware,  software and application  specific  integrated circuit
technology.

The  percentage  of  the  Company's   total  revenue  from   customers   located
internationally  was 31% and 37% in the second quarters of fiscal years 1998 and
1997, respectively, and 31% and 38% in the first six months of fiscal years 1998
and 1997,  respectively.  These percentage decreases are primarily due to growth
at Doctor Design, which has a predominately domestic customer base.

                                      -11-




Costs and Expenses

The  Company's  cost of product  revenue  as a  percentage  of  product  revenue
increased  from 12% in the  second  quarter  of  fiscal  year 1997 to 20% in the
second  quarter  of fiscal  year  1998,  and from 13% in the first six months of
fiscal  year 1997 to 20% in the first six  months  of fiscal  year  1998.  These
percentage  increases were due to increases in the proportion of product revenue
subject  to  third  party  royalty  costs,  the  write-off  of  certain  prepaid
royalties, and increased amortization of capitalized software development costs.

The  Company's  cost of services  revenue as a  percentage  of services  revenue
increased  from 43% in the  second  quarter  of  fiscal  year 1997 to 60% in the
second  quarter  of fiscal  year  1998,  and from 44% in the first six months of
fiscal  year 1997 to 56% in the first six  months  of fiscal  year  1998.  These
percentage  increases  were due to an  increase  in  lower  margin  fixed  price
contracts.  In  particular,  during the second  quarter of fiscal year 1998, the
Company  was  required  to procure a  significant  amount of  materials  with no
associated  margin,  under the terms of a large engineering  services  contract.
Excluding this anomaly, cost of services revenue as a percentage of services was
51% for the second quarter and the first six months of fiscal year 1998.

Marketing  and sales  expenses were $11.2 million and $9.8 million in the second
quarters of fiscal years 1998 and 1997,  respectively,  representing 35% and 38%
of total revenue, respectively, and $21.3 million and $18.7 million in the first
six months of fiscal  years  1998 and 1997,  respectively,  representing  38% of
total revenue in both six month  periods.  The dollar  increases for all periods
presented  were  primarily  due to the  Company's  continued  investment in it's
domestic and international sales and support  infrastructure.  In addition,  the
Company  incurred  employee  terminations  related costs in Europe in the second
quarter of fiscal year 1998.

Research  and  development  expenses  were $4.7  million and $4.4 million in the
second quarters of fiscal years 1998 and 1997,  respectively,  representing  15%
and 17%,  respectively,  of total revenue,  and $9.5 million and $8.1 million in
the first six months of fiscal years 1998 and 1997,  respectively,  representing
17% of total  revenue in both six month  periods.  The dollar  increases for all
periods  presented  were  primarily  the  result  of  increased   personnel  and
consulting expenses associated with the development of the Company's  pRISM+(TM)
development  environment,  MATRIXxR  version  6.0 and  other new  products,  and
enhancing  existing  products.  Costs that are required to be capitalized  under
Statement of Financial Accounting Standards No. 86, "Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed" ("SFAS No. 86") were
$150,000 in the second  quarter of fiscal year 1998  compared to $450,000 in the
second  quarter of fiscal  year 1997,  and  $250,000  in the first six months of
fiscal  year 1998  compared  to  $735,000 in the first six months of fiscal year
1997. The amounts capitalized  represent  approximately 3% of total research and
development  expenditures for the second quarter of fiscal year 1998 compared to
9% in the second  quarter of the previous  fiscal year,  and 3% in the first six
months of fiscal year 1998 compared to 8% in the first six months of fiscal year
1997. The amount of research and development expenditures capitalized in a given
time  period  depends  upon  the  nature  of  the  development   performed  and,
accordingly,  amounts  capitalized  may vary from period to period.  Capitalized
costs are being  amortized  using the greater of the amount  computed  using the
ratio that current gross revenues for a product bear to the total of current and
anticipated future gross revenues for that product,  or on a straight line basis
over three years.  Amortization  for the second  quarter of fiscal year 1998 was
$232,000  compared to $206,000 for the second  quarter of fiscal year 1997,  and
$513,000 in the first six months of fiscal year 1998 compared to $435,000 in the
first six months of fiscal year 1997.

General and  administrative  expenses  were $3.3 million and $2.0 million in the
second quarters of fiscal years 1998 and 1997,  respectively,  representing  10%
and 8% of total revenue,  respectively, and $5.7 million and $4.2 million in the
first six months of fiscal years 1998 and 1997,  respectively,  representing 10%
and 8% of total  revenue,  respectively.  The dollar  increases  for all periods
presented were primarily the result of increased  headcount,  related in part to
the acquisition of Epilogue and the  consolidation  of Diab Data,  combined with
significant growth at Doctor Design.

Acquisition-related  and other costs in the second  quarter and six month period
of fiscal year 1997  comprised the write-off of intangible  assets  related to a
prior acquisition and direct costs related to the acquisition of Epilogue.

Interest and other income was $1.0 million in the second  quarter of fiscal 1998
compared to $0.8 million in the second quarter of fiscal year 1997. The increase
is primarily due to higher interest  earned from increased  holdings of cash and
marketable  securities  in fiscal year 1998.  Interest and other income was $1.8
million in the first six months of fiscal year 1998  compared to $2.2 million in
the first six months of fiscal year 1997.  This decrease is due to the inclusion
in fiscal year 1997 of net operating income of $480,000 from Diab Data which was
required to be accounted  for under the equity  method of  accounting  until the
fourth  quarter of fiscal year 1997,  offset,  in part,  by  increased  interest
income in fiscal year 1998.

Recent Accounting Pronouncements

In February 1997, the Financial  Accounting  Standards Board issued Statement of
Financial Accounting  Standards No. 128 ("SFAS No. 128"),  "Earnings per Share,"
which specifies the computation,  presentation  and disclosure  requirements for
earnings per share. SFAS No. 128 supersedes  Accounting Principles Board Opinion
No. 15, is effective for financial  statements  issued for periods  ending after
December 15, 1997, and requires that prior periods be restated.

In June 1997,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial   Accounting   Standards   No.  130  ("SFAS  No.   130"),   "Reporting
Comprehensive  Income," which establishes  standards of disclosure and financial
statement  presentation for reporting total  comprehensive  income in individual
components.  SFAS No, 130 is effective for fiscal years beginning after December
15, 1997, and will require earlier periods to be restated to reflect application
of the provisions of SFAS No. 130.

In June 1997,  the  Financial  Accounting  Standard  Board  issued  Statement of
Financial  Accounting  Standards  No. 131 ("SFAS No. 131"),  "Disclosures  About
Segments of an Enterprise and Related  Information," which specifies  disclosure
requirements for segment reporting.  The above statements supersedes SFAS No. 14
and SFAS No. 18 and is effective for fiscal years  beginning  after December 15,
1997, and requires earlier years to be restated if practicable.

The impact of the adoption of the above  statements on the financial  statements
of the Company has not yet been determined.


Liquidity and Capital Resources

The Company funds its operations principally through cash flows from operations.
As of August 31, 1997, the Company had $62.5 million of cash,  cash  equivalents
and  marketable  securities.  This  represents  an increase of $7.8 million from
February  28,  1997.  In April  1997,  the Company  announced  that the Board of
Directors  had  authorized a new common stock  repurchase  program  allowing the
Company to  repurchase  up to 1,000,000  shares of common  stock for cash,  from
time-to-time  at market prices.  No time limit was set for the completion of the
program.  In April 1997, the Company  repurchased  20,000 shares of common stock
for $187,500.

Net cash provided by operating  activities during the first six months of fiscal
year 1998 totaled $9.6 million,  as compared to net cash used of $1.8 million in
the first six  months  of fiscal  year  1997.  Net cash  provided  by  operating
activities  increased,  in spite of a  decrease  in net  income,  due  mainly to
changes in accounts  receivable,  accounts  payable,  accrued  payroll and other
accrued liabilities, income taxes payable, and deferred revenue.

Net cash used in investing  activities  totaled  $15.4  million in the first six
months of fiscal year 1998  compared to $27.2  million in fiscal year 1997.  Net
cash used in investing  activities  was higher in fiscal year 1997 due primarily
to the purchase of a building in March 1996.

Net cash provided by financing  activities totaled $1.3 million in the first six
months of fiscal year 1998  compared to $18.4 million in the first six months of
fiscal year 1997. Net cash provided by financing  activities  was  significantly
higher in the first six  months  of fiscal  1997 due to the  issuance  of common
stock in May 1996.  In addition  the  proceeds  from the  exercise of options to
purchase  common stock and purchases under the Employee Stock Purchase Plan were
lower in the first  six  months of fiscal  year  1998.  The first six  months of
fiscal  year 1997 also  benefited  from a large tax benefit  from  disqualifying
dispositions of common stock.

The Company  believes  that cash flows from  operations,  together with existing
cash  balances,  will be adequate to meet the Company's  cash  requirements  for
working  capital,  stock  repurchase  and capital  expenditures  for the next 12
months and the foreseeable future.
