ITEM 2:  ACQUISITION OR DISPOSITION OF ASSETS.

                  On January 26, 1996,  Integrated  Systems,  Inc., a California
corporation  ("Registrant" or "ISI"), acquired control of Doctor Design, Inc., a
California  corporation  ("DDI"),  pursuant to the merger (the  "Merger") of ISI
Purchasing Corporation,  a Delaware corporation and a wholly owned subsidiary of
ISI ("Sub") with and into DDI. The Merger was effected  pursuant to an Agreement
of  Merger  dated  as of  January  26,  1996 by and  between  Sub and DDI and an
Agreement and Plan of  Reorganization  dated as of December 14, 1995, as amended
January 26, 1996 (the  "Plan"),  by and among ISI,  Sub and DDI.  The Merger was
accounted  for as a pooling of interests  and was  structured to be a "tax-free"
reorganization  for federal  income tax  purposes.  The  directors and executive
officers of Registrant were not changed as a result of the Merger.  Prior to the
Merger,  DDI was a provider of high-end  design  services  to the  computer  and
communications  industries,  specializing  in the area of  embedded  multimedia.
After completion of the Merger,  DDI will continue its historical  business as a
wholly owned subsidiary of ISI.

                  Pursuant  to the terms of the Plan,  each  share of DDI Common
Stock  ("DDI  Common  Stock")  issued  and  outstanding  immediately  before the
effective time of the Merger was exchanged for  approximately  .148612 shares of
Registrant's  Common  Stock.  Pursuant to this exchange  ratio,  in the Merger a
total of 371,607 shares of Registrant's Common Stock were issued in exchange for
all of the outstanding DDI Common Stock.  In addition,  Registrant  assumed each
option to purchase DDI Common Stock outstanding immediately before the effective
time of the Merger.  Each DDI option is exercisable for that number of shares of
Registrant's Common Stock equal to .148612 multiplied by the number of shares of
DDI  Common  Stock  purchasable  under the DDI  options  immediately  before the
effective time of the Merger.  Pursuant to this exchange  ratio,  Registrant may
issue up to 131,862  shares of its Common  Stock upon  exercise  of the  assumed
options.  Assuming  exercise of all assumed  options,  Registrant may ultimately
issue a total of up to 503,469  shares of its Common Stock.  The exchange  ratio
was  determined  on the basis of, among other things (i) a comparison of certain
financial and stock market  information  for  Registrant  and certain  financial
information  for DDI  with  similar  types  of  information  for  certain  other
companies  in  businesses  similar  to  those  of  Registrant  and DDI and  (ii)
discussions  between  senior  management  of  Registrant  and DDI  regarding the
business and prospects of their respective companies.

                  The shares of Registrant's Common Stock received by the former
DDI  shareholders  have not been registered under the Securities Act of 1933, as
amended (the "1933  Act"),  in reliance  upon the  exemption  from  registration
provided by Section 3(a)(10) thereof.

                  In connection with the Merger,  ISI, Chemical Trust Company of
California,  as escrow agent,  and the former DDI  shareholders  entered into an
escrow agreement (the "Escrow  Agreement") under which ISI deposited into escrow
stock certificates  representing 10% of the shares of Registrant's  Common Stock
issuable  pursuant  to  the  Merger  and  will  deposit  10% of  the  shares  of
Registrant's  Common  Stock issued upon  exercise of the DDI options  assumed by
Registrant  (the "Escrow  Shares").  The Escrow Shares will be held in escrow as
collateral  for the  indemnification  obligations  of DDI under  the  Plan.  The
indemnification  obligations  of DDI will  expire (i) for items  expected  to be
encountered in the audit process, when ISI receives audited financial statements
together  with a report  thereon  from its  independent  auditors  covering  the
combined results of ISI and DDI for the ISI fiscal year ending February 29, 1996
(but no later than one year from the closing of the Merger),  provided  that ISI
has a  reasonable  period of time,  not to exceed 90 days,  to review  the audit
results to determine  if any claim  exists and must provide  notice of any claim
within  the 90 day  period  and (ii) for all other  items,  12 months  after the
closing of the Merger.

                  Contemporaneously   with  the  Merger,  Marco  Thompson,   the
President  and Chief  Executive  Officer of DDI,  entered  into  employment  and
noncompetition agreements with Registrant. The employment agreement provides for
a three-year  term of employment at a minimum  salary of $150,000 per year and a
target bonus of $125,000, payable upon achievement of certain agreed upon goals.
Upon termination of the employment  agreement by ISI for cause as defined in the
agreement,  all compensation and benefits payable under the employment agreement
are  payable  through  the date of  termination.  The  noncompetition  agreement
provides  that Mr.  Thompson  will not compete with  Registrant  for a period of
three years following the Merger.

                                      - 2 -


                  In connection with the Merger,  Mr. Thompson also  transferred
to ISI  ownership  of the  building  in which a portion of the DDI  business  is
located and  terminated  DDI's lease of the premises,  in  consideration  of ISI
paying the outstanding debt on the property.  The number of shares issued to Mr.
Thompson in the Merger in exchange for his DDI Common Stock was reduced by 8,199
shares  or  $280,406,  which  is the  amount  that the  outstanding  debt on the
property exceeded the appraised current fair market value of the property.

ITEM 7(A):        FINANCIAL STATEMENTS OF BUSINESS ACQUIRED.

                         Report of Independent Auditors


To the Board of Directors
Doctor Design, Inc.
San Diego, California

We have audited the  accompanying  balance sheets of Doctor  Design,  Inc. as of
June 30, 1995 and 1994,  and the  related  statements  of income,  shareholders'
equity, and cash flows for the years then ended. These financial  statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of Doctor Design, Inc. as of June
30, 1995 and 1994,  and the results of its operations and its cash flows for the
years then ended in conformity with generally accepted accounting principles.

NOTE 1.  NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

NATURE OF BUSINESS

Doctor Design,  Inc. (the  "Company")  provides  engineering  design services to
manufacturers of high technology products. For certain design service contracts,
the Company retains commercialization or proprietary rights to the technology it
has developed for the customer. The Company is also involved in the sale of high
technology  products  to  design  service  customers  which  include  internally
developed software applications.

A summary of the Company's significant accounting policies follows:

REVENUE RECOGNITION

Revenue is recognized  based on the type of contract.  Revenue earned under time
and material contracts is recognized on the basis of hours of work performed and
hourly rates provided under the contract.  Revenue from fixed-price contracts is
recognized on the percentage-of-completion method, measured by the percentage of
total  hours  incurred  to date  to  estimated  total  hours  of each  contract.
Management  believes that these methods  provide the best  available  measure of
progress on these contracts.

Contract  costs include all direct  material and labor costs and those  indirect
costs  related to contract  performance,  such as indirect  labor and  supplies.
Selling,  general and  administrative  costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted  contracts are made in the period
in which such losses are determined.  Changes in contract performance,  contract
conditions,  and  estimated  profitability  may result in revisions to costs and
income and are recognized in the period in which the revisions are determined.

The asset,  "Costs and estimated  earnings in excess of billings on  uncompleted
contracts,"  represents  revenue  recognized  in excess of amounts  billed.  The
liability,  "Billings in excess of costs and estimated  earnings on  uncompleted
contracts," represents billings in excess of revenue recognized.

Revenue is deferred for future  recognition  when a  contractual  obligation  to
provide  services or a third  party's  right to developed  assets  exists.  Such
revenue is  recognized  as the  contractual  obligation  or third party right is
satisfied.

CASH AND CASH EQUIVALENTS

Cash and cash  equivalents  include  highly  liquid  investments  with  original
maturities of three months or less.

The Company  maintains its cash accounts in two commercial banks and a brokerage
account located in San Diego,  California.  The two commercial bank accounts are
insured by Federal Deposit Insurance  Corporation (FDIC) up to $100,000 each. At
June 30, 1995,  the Company had  balances of  approximately  $422,000  that were
either uninsured or in excess of the FDIC insurance limit.

PROPERTY AND EQUIPMENT

Property and equipment is stated at cost. Depreciation of property and equipment
used in production of the Company's hand-held computer product is computed using
the  units-of-production  method over the estimated number of units which can be
produced  with the assets.  Depreciation  of other  property  and  equipment  is
computed using the straight-line  method over estimated useful lives of three to
five years. Maintenance and repair costs are expensed as incurred.

                                      -8-




SOFTWARE DEVELOPMENT COSTS

Software  development  costs,  as an  integral  part of the  development  of the
Company's hand-held computer and graphics display  controller,  were capitalized
once  the  technological  feasibility  of the  specific  software  projects  was
established.  Capitalization  of such costs  ceased  when the final  product was
fully tested and available for general  distribution to customers.  Amortization
of capitalized  software  development costs began when the product was ready for
general distribution to customers.  Amortization is computed based on the number
of units  delivered  compared with the number of estimated units to be delivered
or the straight-line  method over the remaining  estimated  economic life of the
product,  whichever  provides  a  shorter  amortization  period.  The  estimated
economic life of the hand-held computer was five years. All software development
costs have been fully amortized at June 30, 1995.

Other research and development costs are charged to expense when incurred.

INCOME TAXES

Deferred taxes are provided on a liability  method  whereby  deferred tax assets
are recognized for deductible  temporary  differences and operating loss and tax
credit  carryforwards  and deferred tax  liabilities  are recognized for taxable
temporary  differences.  Temporary  differences are the differences  between the
reported  amounts of assets and  liabilities  and their tax bases.  Deferred tax
assets are reduced by a valuation  allowance when, in the opinion of management,
it is more likely than not that some  portion or all of the  deferred tax assets
will not be realized.  Deferred tax assets and  liabilities are adjusted for the
effects of changes in tax laws and rates on the date of enactment.



NOTE 2.  COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS

Costs and estimated earnings on uncompleted  contracts at June 30, 1995 and 1994

Customer B also  provided  funding for and holds certain  contractual  rights to
assets developed by the Company,  consisting mainly of tooling and molds for the
production  of its  hand-held  computer.  Accordingly,  the Company had deferred

industries.

The Company has a stock option plan (the "Plan") which provides for the granting
of both qualified and non-qualified options to employees,  directors and outside
consultants  of the Company.  Options are  exercisable  at various dates through
June  2003.  The terms of the Plan  provide  for the  granting  of options at an
exercise  price  approximating  the fair market  value of the  Company's  common
stock, as determined by the Option  Committee of the Board of Directors,  on the
date of the grant of such options.  Under the Plan options for 1,500,000  shares
may be granted.  The options vest over periods  ranging from 0 to 4 years and at
June 30, 1995 and 1994,  options for 431,959 and 347,925  shares,  respectively,
were exercisable and options for 234,205 and 530,705 shares, respectively,  were
available for future grant.  Subsequent to June 30, 1995, an additional  134,000
options were granted at $0.40 per share.

In November 1993, the Company  accepted a nonrecourse note receivable as payment
for stock options  exercised.  This note is non interest  bearing and is due and
payable on December 31, 1996. At June 30, 1995, the 76,602 shares related to the

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS


1.       BASIS OF PRESENTATION

         The Doctor  Design,  Inc.  statements of operations for the years ended
June 30, 1993 and 1994 and December 31, 1994 and the  Integrated  Systems,  Inc.
consolidated  statements  of income for the three years ended  February 28, 1995
have  been  combined.  The  combined  financial  statements  include  pro  forma
adjustments  to include the effect of  ownership  of a building in which  Doctor
Design is located.  This building was owned by a majority  shareholder of Doctor
Design during the periods reported.  Additionally,  the Doctor Design statements
of  operations  for the nine months  ended  September  30, 1995 and 1994 and the
Integrated Systems  consolidated  statements of income for the nine months ended
November 30, 1994 and 1995 have been combined.  This method of combining the two
companies is for the  presentation  of unaudited  pro forma  condensed  combined
financial  statements only. The unaudited pro forma condensed combined financial
statements,  including the notes thereto, should be read in conjunction with the
historical  consolidated  financial  statements of Doctor Design included herein
and those of Integrated Systems.

         No adjustments have been made to conform the accounting policies of the
combining companies. The nature and extent of such adjustments,  if any, will be
based upon further study and analysis and are not expected to be significant.


2.       UNAUDITED PRO FORMA COMBINED NET INCOME PER SHARE

         The unaudited pro forma  combined  statements of operations  for Doctor
Design and  Integrated  Systems have been  prepared as if the  acquisition  were
completed at the beginning of the earliest periods presented.  The unaudited pro
forma  combined net income per share is based on the combined  weighted  average
number of common and common  equivalent shares of Doctor Design common stock and
Integrated  Systems  common  stock for each period,  based upon the  acquisition
exchange ratio.


3.       PRO FORMA UNAUDITED COMBINED SHARES OUTSTANDING

         These  unaudited pro forma combined  financial  statements  reflect the
issuance of approximately  372,000 shares of Integrated  Systems common stock in
exchange for an aggregate of  approximately  2,501,000  shares of Doctor  Design
common  stock in  connection  with  the  acquisition  based  on the  acquisition
exchange ratio of 0.1486 shares of Integrated Systems common stock for every one
share of Doctor Design common stock.



The following table details the pro forma share issuances in connection with the
acquisition:


                                                                  Doctor Design                  Integrated Systems
                                                                  Common Shares      Exchange      Common Shares
                                                                   Outstanding        Ratio          Outstanding
                                                                 ----------------   ------------     -------------
                                                                                                   
Doctor Design shares outstanding as of November 30, 1995             2,501,000          0.1486          372,000
Integrated Systems shares outstanding as of November 30 1995                                         10,190,000
                                                                                                     ----------
Total number of shares of Integrated Systems common stock
     outstanding after completion of the acquisition                                                 10,562,000
                                                                                                     ----------








         In addition,  Integrated Systems assumed all options to purchase Doctor
Design common stock  outstanding  immediately  before the effective  time of the
acquisition.  Each  Doctor  Design  option  is  exercisable  for that  number of
Integrated  Systems'  common stock equal to 0.1486  multiplied  by the number of
shares of Doctor Design purchasable under the Doctor Design option.  Pursuant to
this exchange ratio,  Integrated  Systems may issue up to approximately  132,000
shares of common stock upon exercise of the assumed options.  Assuming  exercise
of all assumed options, Integrated Systems may ultimately issue a total of up to
approximately 504,000 shares of Common Stock.


4.       MERGER RELATED EXPENSES

         Doctor Design and  Integrated  Systems  estimate they will incur direct
transaction  costs of  approximately  $500,000  associated  with the acquisition
consisting of transaction fees for attorneys and accountants. These nonrecurring
transaction  costs will be charged to  operations  primarily  during the quarter
ended February 29, 1996.

         The Unaudited Pro Forma Condensed  Combined  Balance Sheet gives effect
to estimated direct  transaction  costs as if such costs had been incurred as of
November 30, 1995.  These costs are not  reflected  in the  Unaudited  Pro Forma
Condensed Combined Statements of Operations.
