1.   Quarterly Financial Statements
     ------------------------------
       The condensed consolidated financial statements and related notes for the
periods ended April 30, 1999 and 1998 are unaudited but include all  adjustments
(consisting solely of normal recurring adjustments) which are, in the opinion of
management,  necessary for a fair  presentation  of the  financial  position and
results of  operations  of the Company for the interim  periods.  The results of
operations  for the periods  ended  April 30, 1999 and 1998 are not  necessarily
indicative of the operating results to be expected for the full fiscal year. The
information  included  in this  report  should be read in  conjunction  with the
Company's audited  consolidated  financial  statements and notes thereto for the
fiscal year ended October 31, 1998 included in the Company's  most recent Annual
Report  on Form  10-K and the  additional  risk  factors  contained  herein  and
therein,  including,  without limitation,  risks relating to fluctuations in our
quarterly net sales and  operating  results,  limited  systems  sales;  backlog,
cyclicality  of  semiconductor  industry,  management  of  fluctuations  in  our
operating  results,  expansion of our product lines,  limited sources of supply,
reliance on our subcontractors, highly competitive industry, rapid technological
change,  importance  of timely  product  introduction,  customer  concentration,
lengthy sales cycle,  risks associated with  acquisitions,  changes in financial
accounting  standards and  accounting  estimates,  dependence on key  personnel,
transition in our executive management, international sales, proprietary rights,
future capital needs;  leverage,  year 2000 readiness disclosure,  volatility of
our stock price and effects of certain anti-takeover provisions, as set forth in
this Report.  Any party  interested in reviewing a free copy of the Form 10-K or
the  Company's  other  publicly  available  documents  should write to the Chief
Financial Officer of the Company.

       Use  of  Estimates  -  The  preparation  of  the  accompanying  unaudited
consolidated   condensed  financial   statements  requires  management  to  make
estimates  and  assumptions  that affect the amounts  reported in the  financial
statements. Actual results could differ from those estimates.


2.   Inventories

       Inventories are stated at the lower of standard cost (which  approximates
first-in,  first-out cost) or market.  Inventories  consist of the following (in
thousands):

3.   Net Income (Loss) Per Share
     ---------------------------

       Net income  (loss) per basic  share is based  upon the  weighted  average
number of common  shares  outstanding  during the period.  Net income (loss) per
diluted share is based upon the weighted  average  number of common and dilutive
potential common shares outstanding during the period. The Company's Convertible
Subordinated  Notes are not dilutive  potential common shares and,  accordingly,
were  excluded  from the  calculation  of net income  (loss) per diluted  share.
Options to purchase approximately 2,012,000 shares at an average price of $16.79
per share were  outstanding  at April 30,  1999,  but were not  included  in the
computation of diluted net loss per share because  options are  antidilutive  in
periods when the Company incurs a net loss.

4.     Changes in Accounting Standards
       -------------------------------

       As of  November  1,  1998 the  Company  adopted  Statement  of  Financial
Accounting Standards No. 130 "Reporting Comprehensive Income" ("SFAS 130"). SFAS
130 established new rules for the reporting and display of comprehensive  income
(loss) and its components  including unrealized gains or losses on the Company's
available-for-sale  securities  and foreign  currency  translation  adjustments,
which prior to adoption were  immaterial  and were  therefore  excluded from net
income  (loss).  For the fiscal  quarters  ended April 30, 1999 and 1998,  total
comprehensive  income  (loss)  amounted to $ (5.1  million)  and $ 8.7  million,
respectively.  For the six month  periods  ended April 30, 1999 and 1998,  total
comprehensive  income  (loss)  amounted to $ (11.5  million) and $ 17.7 million,
respectively.

5.     Contingencies
       -------------

       The Company is involved in various claims arising in the ordinary  course
of  business,  none of  which,  in the  opinion  of  management,  if  determined
adversely  against  the  Company,  will have a  material  adverse  effect on the
Company's business, financial condition or results of operations.

6.     Special Charges and Extraordinary Item
       --------------------------------------

       In the second  quarter  of fiscal  1999,  the  Company  recorded  special
charges of $6.2 million. These charges were primarily from costs relating to the
disposal of excess facilities and severance.  Cash expenditures  associated with
these special  charges  during the quarter were  approximately  $290,000.  It is
expected that approximately $1.8 million of cash expenditures  related to excess
facilities  will  be paid  out in the  second  half of  fiscal  year  1999.  The
remaining $4.1 million relates to non-cash asset disposals.

       As of April 30, 1999, approximately $1.7  million in accrued  liabilities
related to special  charges  recorded in 1998 remained on the Company's  balance
sheet, primarily  representing rent on excess facilities.  These amounts will be
paid out over the next six months.

       During the second quarter,  the Company recorded an extraordinary gain of
$1.2  million,  net of tax of $652,000 on the exchange of 328,000  shares of the
Company's  common stock held in treasury for an aggregate of $9,040,000 of its 5
1/4% Convertible  Subordinated Notes due 2002. The Company may engage in similar
transactions in the future.

RESULTS OF OPERATIONS

NET SALES

       Net sales  consist of  revenues  from  systems  sales,  spare part sales,
maintenance  contracts and software sales.  Net sales were $38.1 million for the
second  quarter of fiscal  1999,  representing  a decrease of 49.0% from the net
sales of $74.7 million in the  comparable  period of fiscal 1998.  This decrease
was due primarily to a significant decline in worldwide demand for semiconductor
automatic test equipment,  particularly in the Asia Pacific region and to delays
in revenue  shipments of new  products.  International  net sales  accounted for
approximately72.4% of the total net sales for the second quarter of fiscal 1999,
compared  to  approximately  80% for  the  comparable  period  a year  ago.  The
Company's  international  sales of its  products and spare parts and its service
revenues are denominated primarily in United States dollars.

GROSS MARGIN

       The Company's gross margin has been and will continue to be affected by a
variety of factors, including manufacturing efficiencies, pricing by competitors
and suppliers, new product introductions,  product sales mix, production volume,
customization and  reconfiguration of systems,  international and domestic sales
mix and field service margins.  Gross margin was 50.1% for the second quarter of
fiscal 1999,  compared  with 57.6% for the second  quarter of fiscal  1998.  The
decrease in gross  margin as a percent of sales was due to  significantly  lower
average  selling  prices,  to  higher  costs  caused  by   under-absorption   of
manufacturing  expenses,  and to product  development  delays  which the Company
believes  will continue to adversely  affect gross margins  through at least the
end of the current fiscal year.

RESEARCH AND DEVELOPMENT

       Research and development ("R&D") expenses were $9.1 million in the second
quarter of fiscal 1999, a decrease of $3.1 million or 25.2% over the same period
of fiscal 1998.  The decrease was  primarily  due to reduced  payroll and travel
related  expenses from lower headcount as well as cutbacks in project,  software
and other  miscellaneous  expenses.  As a percentage of net sales,  R&D expenses
were 24.0% for the second  quarter of fiscal 1999, an increase from 16.4% in the
second quarter of fiscal 1998. The increase in these expenses as a percentage of
net sales is attributable  primarily to the significant decrease in net sales in
the second  quarter of fiscal 1999 as  compared  with the  comparable  period of
fiscal 1998.  The Company  currently  intends to continue to invest  significant
resources  in  the  development  of  new  products  and   enhancements  for  the
foreseeable future. Accordingly,  the Company expects these expenses to increase
in absolute dollars for the remainder of fiscal 1999.

SELLING, GENERAL AND ADMINISTRATIVE

       Selling,  general and administrative expenses ("SG&A") were $13.9 million
in the  second  quarter of fiscal  1999,  representing  a $4.1  million or 22.6%
decrease from the comparable  period of fiscal 1998.  The spending  decline from
the prior quarter is primarily due to reduced sales  commissions  on lower sales
volume,  reduced payroll and travel related expenses from lower headcount and to
reductions in corporate and other project related  expenses.  As a percentage of
net sales,  SG&A  expenses  were 36.4% for the  second  quarter of fiscal  1999,
compared with 24.0% for the  corresponding  period in fiscal 1998. This increase
as a percentage of net sales is primarily due to the decrease in net sales.  The
Company  expects SG&A  expenses for the  remainder of fiscal 1999 to increase in
absolute  dollars.  Increases  expected in the remainder of fiscal 1999 include,
but are not  necessarily  limited to, the costs of  installing a new MIS system,
increases  in  salaries  of  existing  employees  and the  costs of  moving  the
Company's primary Oregon operations into a new facility.

SPECIAL CHARGES AND EXTRAORDINARY ITEM

       In the second  quarter  of fiscal  1999,  the  Company  recorded  special
charges of $6.2 million. These charges were primarily from costs relating to the
disposal of excess facilities and severance.  Cash expenditures  associated with
these special  charges  during the quarter were  approximately  $290,000.  It is
expected that approximately $1.8 million of cash expenditures  related to excess
facilities  will  be paid  out in the  second  half of  fiscal  year  1999,  the
remaining $4.1 million relates to non-cash asset disposals.

       As of April 30, 1999,  approximately $1.7 million in accrued  liabilities
related to special  charges  recorded in 1998 remained on the Company's  balance
sheet, primarily representing rent on excess facilities.
These amounts will be paid out over the next six months.

       During the second quarter,  the Company recorded an extraordinary gain of
$1.2 million,  net of tax of $652,000  onthe  exchange of 328,000  shares of the
Company's  common stock held in treasury for an aggregate of $9,040,000 of its 5
1/4% Convertible  Subordinated Notes due 2002. The Company may engage in similar
transactions in the future.

INTEREST AND OTHER INCOME EXPENSES, NET

       Net interest and other  expenses  for the second  fiscal  quarter of 1999
stood at $240,000, up $40,000 from the second fiscal quarter of 1998 largely due
to the reduction of bond interest expense.

INCOME TAXES

       The Company's  estimated  effective tax rate for the first half of fiscal
1999 was 36%,  compared to 34% in the first six months of 1998.  The tax rate is
computed based on projected fiscal year to date book income or loss. Realization
of a portion of the net  deferred  tax assets at April 30, 1999 is  dependent on
the Company's  ability to generate  approximately  $34,000,000 of future taxable
income. Management believes that it is more likely than not that the assets will
be realized based on forecasted income.  However, there can be no assurance that
the  Company  will meet its  expectations  of  future  income.  Management  will
evaluate the  realizability  of the deferred tax assets quarterly and assess the
need for additional valuation allowances.

YEAR 2000 READINESS DISCLOSURE

       The "Year  2000" issue  results  from the use in  computer  hardware  and
software of two digits  rather than four digits to define the  applicable  year.
When computer  systems must process dates both before and after January 1, 2000,
two-digit year "fields" may create processing  ambiguities that can cause errors
and system failures. The results of these errors may range from minor undetected
errors to complete shutdown of an affected system.  These errors or failures may
have  limited  effects,  or the  effects  may be  widespread,  depending  on the
computer chip, system or software, and its location and function. The effects of
the Year 2000 problem are exacerbated because of the interdependence of computer
and  telecommunications  systems in the United States and  throughout the world.
Because  of this  interdependence,  the  failure  of one  system may lead to the
failure of many other systems even though the other systems are themselves "Year
2000 compliant."

       Our Board of Directors has reviewed the Year 2000 issue  generally and as
it may affect our business  activity  specifically.  We are  implementing a Year
2000 plan (the  "Plan")  which is  designed to cover all of our  activities  and
which  is  monitored  by the  Board of  Directors.  We will  modify  the Plan as
circumstances change. Under the Plan, we are using a five-phase  methodology for
addressing  the  issue.  The  phases  are  Awareness,  Assessment,   Renovation,
Validation and Implementation.

       The  Awareness  phase  consisted  of defining  the Year 2000  problem and
gaining   executive   level  support  and  sponsorship  for  addressing  it.  We
established a Year 2000 program team and created an overall strategy. During the
Assessment phase, we inventoried all internal systems, products and supply chain

                                       10
<PAGE>

partners and  prioritized  each for  renovation.  We believe we have completed a
majority of the Awareness and Assessment  phases;  however,  we will continue to
work in these areas as we complete  our  assessment  of  existing  supply  chain
partners and enter into new supply chain relationships in the ordinary course of
business. Renovation consists of converting, replacing, upgrading or eliminating
systems   that  have  Year  2000   problems.   We  have  begun   Renovation   on
mission-critical  systems and have completed all but two systems as of April 30,
1999.  The  remaining  two  mission-critical   systems  are  now  scheduled  for
completion  of renovation by October  1999.  Validation  involves  ensuring that
hardware and software  fixes will work properly in 1999 and beyond and can occur
both before and after implementation. We began the Validation phase in late 1998
and will continue through October, 1999 to allow for thorough testing before the
Year 2000.  Implementation  is the  installation of Year 2000 ready hardware and
software components in a live environment.

       The impact of Year 2000  issues on our  business  will depend not only on
corrective  actions  that we  take,  but also on the way Year  2000  issues  are
addressed by  governmental  agencies,  businesses  and other third  parties that
provide us with  services or data or receive  services or data from us, or whose
financial condition or operational capability is important to us. To reduce this
exposure,   we  have  an  ongoing   process  of   identifying   and   contacting
mission-critical  third party  vendors and other  significant  third  parties to
determine their Year 2000 plans and target dates. Risks associated with any such
third parties  located  outside the United States may be higher insofar as it is
generally  believed that non-U.S.  businesses  may not be addressing  their Year
2000  issues  on as  timely  a basis  as U.S.  businesses.  Notwithstanding  our
efforts, we cannot be certain that we,  mission-critical  third party vendors or
other significant third parties will adequately address their Year 2000 issues.

       We  are   developing   contingency   plans   in  the   event   that   we,
mission-critical  third party vendors or other significant third parties fail to
adequately address Year 2000 issues.  Such plans principally involve identifying
alternative  vendors or  internal  remediation.  We cannot  ensure that any such
plans will fully mitigate any such failures or problems.  Furthermore, there may
be certain mission-critical third parties, such as utilities,  telecommunication
companies, or material vendors for which alternative arrangements or sources are
limited or unavailable.

       Although  it  is  difficult  for  us  to  estimate  the  total  costs  of
implementing  the  Plan,  our  current  estimate  is  that  such  costs  will be
approximately $2.5 million through October 1999 and beyond. However, although we
believe that our estimates are reasonable, we cannot be certain, for the reasons
stated in the next  paragraph,  that the actual costs of  implementing  the Plan
will not differ  materially from the estimated  costs. We have incurred costs of
approximately $1.5 million through April 30, 1999 in connection with the Plan. A
significant  portion of total  Year 2000  project  expenses  is  represented  by
existing staff that have been redeployed to this project. We do not believe that
the  redeployment  of existing staff will have a material  adverse effect on our
business,  results  of  operations  or  financial  position.  Nor  do we  expect
incremental  expenses  related  to the Year 2000  project to  materially  impact
operating results in any one period.

       For a number of reasons,  we cannot  predict or  quantify  the extent and
magnitude of the Year 2000 problem as it will affect our business, either before
or for some period after January 1, 2000. Among the most important  reasons are:

     o    lack of control  over systems  used by third  parties  critical to our
          operation;

     o    dependence  on third  party  software  vendors  to  deliver  Year 2000
          upgrades in a timely manner;

     o    complexity of testing  inter-connected  networks and applications that
          depend on third party networks; and

     o    the uncertainty surrounding how others will deal with liability issues
          raised by Year 2000 related failures.

       For example, we cannot be certain that systems used by third parties will
be Year 2000 ready by January 1, 2000,  or by some  earlier  date,  so as not to
create a material disruption to our business.  Moreover,  the estimated costs of
implementing  the Plan do not take into account the costs, if any, that might be
incurred  as a result of Year  2000-related  failures  that  occur  despite  our
implementation of the Plan.

                                       11
<PAGE>

       Although we are not aware of any material  operational  issues associated
with preparing our internal systems for the Year 2000 or of material issues with
respect to the  adequacy  of  mission-critical  third party  systems,  we cannot
ensure that we will not experience material  unanticipated negative consequences
and/or material costs caused by undetected  errors or defects in such systems or
by our failure to adequately  prepare for the results of such errors or defects,
including  the  costs  of  related  litigation,  if  any.  The  impact  of  such
consequences  could have a material  adverse  effect on our business,  financial
condition or results of operations.

INTRODUCTION OF THE EURO

       To date the introduction and the use of the Euro has not had nor does the
Company expect it to have a material  adverse effect on our business,  financial
condition or results of operations.

LIQUIDITY AND CAPITAL RESOURCES

       Net cash provided by operating  activities  was $18.1 million for the six
months  ended  April 30,  1999.  This cash flow from  operating  activities  was
primarily  attributable to net income before  depreciation  and amortization and
special  charges of  approximately  $5  million,  income tax  receipts  of $17.2
million,  offset by cash used for net changes in the remaining  operating assets
and liabilities.

       Net cash used for  investing  activities  was $14.8  million  for the six
months  ended  April  30,  1999.  Cash  flow used in  investing  activities  was
primarily   attributable   to   acquisitions   of  property  and   equipment  of
approximately $10.1 million, and net purchases of available-for-sale  securities
of approximately $3.1 million.

       Net cash  provided by financing  activities  was $5.0 million for the six
months  ended  April 30,  1999.  This cash flow from  financing  activities  was
primarily  attributable  to treasury stock and common stock issued in accordance
with the Company's employee equity compensation plans.

       The Company  recorded a non-cash  transaction  during the quarter for the
exchange of 328,000 shares of the Company's common Stock held in treasury for an
aggregate of $9,040,000 of its 5 1/4% Convertible  Subordinated  Notes due 2002.
This transaction  resulted in an extraordinary gain of $1.2 million,  net of tax
of  $652,000  as well as an  increase  in  additional  paid-in  capital  of $2.1
million.

       As of April 30, 1999,  the Company had working  capital of  approximately
$159 million  including cash and short-term  investments of $104 million,  $34.4
million of accounts  receivable  and $32.3 million of  inventories.  The Company
expects its accounts  receivable to continue to represent a significant  portion
of working  capital.  The Company  believes that because of the relatively  long
manufacturing  cycles of many of its  testers  and the new  products  it has and
plans to continue to introduce, investments in inventories will also continue to
represent a significant portion of working capital.  Significant  investments in
accounts  receivable and  inventories may subject the Company to increased risks
which  could  materially  adversely  affect the  Company's  business,  financial
condition and results of operations.  Total current liabilities of $40.9 million
as of October  31, 1998  increased  to $42.2  million for the six months  ending
April 30, 1999.

       The  Company's  principal  sources  of  liquidity  as of April  30,  1999
consisted  of  approximately   $56.7  million  of  cash  and  cash  equivalents,
short-term  investments  of $47.2  million and $40 million  available  under the
Company's  unsecured  working  capital line of credit expiring July 23, 1999. In
addition,  the  Company  has $38.9  million  of  available  for sale  securities
classified as long-term. As of April 30, 1999, no amounts were outstanding under
the unsecured  line of credit.  Additionally,  as of April 30, 1999, the Company
had operating  lease  commitments  for facilities  and test and other  equipment
totaling approximately $45.8 million.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

       The  Company's  exposure to market  risk for  changes in  interest  rates
relates  primarily to the Company's  investment  portfolio  and  long-term  debt
obligations.  The Company maintains a strict investment policy which ensures the
safety and preservation of its invested funds by limiting  default risk,  market

                                       12
<PAGE>

risk, and reinvestment  risk. The Company's  investments  consists  primarily of
commercial paper, medium term notes, asset backed securities, US. Treasury notes
and  obligations of U.S.  Government  agencies,  bank  certificates  of deposit,
auction rate preferred  securities,  corporate  bonds and municipal  bonds.  The
table below  presents  notional  amounts and related  weighted-average  interest
rates by year of maturity for the Company's  investment  portfolio and long-term
debt obligations (in thousands, expect percent amounts):

       The Company mitigates default risk by attempting to invest in high credit
quality  securities  and by  constantly  positioning  its  portfolio  to respond
appropriately  to a significant  reduction in a credit rating of any  investment
issuer or guarantor.  The portfolio  includes only  marketable  securities  with
active secondary or resale markets to ensure portfolio liquidity and maintains a
prudent amount of diversification.

       The Company has no current cash flow exposure due to rate changes for its
$106 million Convertible  Subordinated Notes. The Company has a $40 million line
of credit under which it can borrow either at the bank's prime rate or the LIBOR
rate.  As of April 30,  1999,  the Company had no  borrowings  under its line of
credit.

</TABLE>


       A variety of factors affect our net sales and results of operations.  The
above graph  illustrates that our quarterly net sales and operating results have
fluctuated  significantly.  We believe  they will  continue to  fluctuate  for a
number  of  reasons,  including:

     o    economic  conditions  in the  semiconductor  industry  in general  and
          capital equipment industry specifically;

     o    timing of new product  announcements and new product releases by us or
          our competitors;
     o    market  acceptance  of our  new  products  and  enhanced  versions  of
          existing products;

     o    manufacturing  inefficiencies  associated with the start-up of our new
          products,  changes in our  pricing or payment  terms and  cycles,  and
          those of our competitors, customers and suppliers;

     o    manufacturing  capacity and ability to volume produce systems and meet
          customer requirements;

     o    write-offs  of excess  and  obsolete  inventories,  and  uncollectible
          receivables;

     o    patterns of capital spending by our customers,  delays,  cancellations
          or  rescheduling   of  customer  orders  due  to  customer   financial
          difficulties or otherwise;

     o    changes in overhead  absorption levels due to changes in the number of
          systems manufactured,  the timing and shipment of orders, availability
          of  components   including  custom   integrated   circuits   ("IC's"),
          subassemblies  and  services,  customization  and  reconfiguration  of
          systems and product reliability;

     o    expenses associated with acquisitions and alliance

     o    operating expense  reductions,  including costs relating to facilities
          consolidations, excess facilities and related expenses;

     o    the  proportion of our direct sales and sales  through third  parties,
          including  distributors and original equipment  manufacturers ("OEM"),
          the mix of  products  sold,  the  length  of  manufacturing  and sales
          cycles, product discounts; and

     o    natural  disasters,  political  and economic  instability,  regulatory
          changes and outbreaks of hostilities.

       We presently  are  introducing  and will  continue to introduce  many new
products and product enhancements in the future, the timing and success of which
will affect our business,  financial  condition and results of  operations.  Our

                                       14
<PAGE>

gross  margins on system sales have varied  significantly,  and will continue to
vary  significantly  based on a variety of factors,  including:

     o    manufacturing inefficiencies;

     o    pricing  concessions  by us and our  competitors  and  pricing  by our
          suppliers;

     o    hardware and software product sales mix;

     o    inventory write-downs;

     o    production volume;

     o    new product introductions;

     o    product reliability;

     o    absorption levels and the rate of capacity utilization;

     o    customization and reconfiguration of systems;

     o    international and domesti sales mix and field service margins; and

     o    facility relocations and consolidations.

       New and enhanced products typically have lower gross margins in the early
stages of commercial introduction and production.  Although we have recorded and
continue  to  record  provisions  for  estimated  sales  returns,  uncollectible
accounts,  and product  warranty  costs, we cannot be certain that our estimates
will be  adequate.  We may be required to record  charges in future  quarters to
reflect, in part, the cost of additional facilities consolidation, as it occurs.

       We  cannot  forecast  with any  certainty  the  impact of these and other
factors on our sales and operating  results in any future  period.  In addition,
our need for continued  significant  expenditures  for research and development,
marketing and other expenses for new products,  capital equipment  purchases and
worldwide training and customer service and support,  among other factors,  will
make  it  difficult  for  us to  reduce  our  significant  fixed  expenses  in a
particular  period if we don't meet our net sales  goals for that  period.  As a
result,  we cannot be certain  that we will become  profitable  again or that we
will not  continue  to sustain  losses in the  future.  We  believe  that we may
continue to incur  quarterly  net losses  through  the fourth  quarter of fiscal
1999.  As a result,  the price of our common stock may continue to be materially
adversely affected.

Limited Systems Sales; Backlog
- ------------------------------

       We  derive a  substantial  portion  of our net  sales  from the sale of a
relatively  small number of systems that typically  range in price from $350,000
to $3.6 million,  other than certain memory products and software products,  for
which the price range is typically below $50,000. As a result, our net sales and
operating results for a particular period could be significantly impacted by the
timing of  recognition of revenue from a single  transaction.  Our net sales and
operating  results for a particular  period could also be  materially  adversely
affected if an anticipated  order from even one customer is not received in time
to permit  shipment  during that period.  Backlog at the  beginning of a quarter
typically does not include all orders  necessary to achieve our sales objectives
for that quarter.  In addition,  orders in backlog are subject to  cancellation,
delay,  deferral or  rescheduling  by customers  with  limited or no  penalties.
Consequently, our quarterly net sales and operating results have in the past and
will in the future depend upon our obtaining orders for systems to be shipped in
the same quarter that the order is received.

       Furthermore,  we ship certain  products  generating most of our net sales
near the end of each quarter. Accordingly, our failure to receive an anticipated
order or a delay or  rescheduling  in a  shipment  near the end of a  particular
period may cause net sales in a particular  period to fall  significantly  below
expectations,  which  could  have a  material  adverse  effect on our  business,
financial condition or results of operations.  The relatively long manufacturing
cycle of many testers has caused and could continue to cause future shipments of
testers  to be delayed  from one  quarter to the next,  which  could  materially
adversely  affect our business,  financial  condition or results of  operations.

                                       15
<PAGE>

Furthermore,  as we and our competitors  announce new products and technologies,
customers  may defer or cancel  purchases of our existing  systems,  which could
have a material adverse effect on our business,  financial  condition or results
of operations. We cannot forecast the impact of these and other factors on sales
and operating results.

Cyclicality of Semiconductor Industry
- -------------------------------------

       Our business and results of  operations  depend  largely upon the capital
expenditures of manufacturers of semiconductors and companies that specialize in
contract packaging and/or testing of semiconductors, including manufacturers and
contractors that are opening new or expanding existing fabrication facilities or
upgrading  existing  equipment,  which  in turn  depend  upon  the  current  and
anticipated  market  demand  for   semiconductors  and  products   incorporating
semiconductors.  The  semiconductor  industry  has  been  highly  cyclical  with
recurring  periods of  oversupply,  which often have had a severe  effect on the
semiconductor  industry's  demand for test  equipment,  including the systems we
manufacture  and market.  We believe that the markets for newer  generations  of
semiconductors will also be subject to similar fluctuations.

       We have experienced  shipment delays,  delays in commitments and purchase
order   restructurings   by  several   customers   and  we  expect   delays  and
restructurings may continue.  Accordingly,  we cannot be certain that we will be
able to  achieve or  maintain  our  current  or prior  level of sales or rate of
growth.  We anticipate that a significant  portion of new orders may depend upon
demand from semiconductor device manufacturers building or expanding fabrication
facilities  and new device  testing  requirements  that are not  addressable  by
currently  installed  test  equipment,  and there can be no assurance  that such
demand  will  develop to a  significant  degree,  or at all.  In  addition,  our
business, financial condition or results of operations may be adversely affected
by any factor  adversely  affecting  the  semiconductor  industry  in general or
particular  segments  within  the  semiconductor   industry.  The  recent  Asian
financial  crisis has contributed to a widespread  uncertainty and a slowdown in
the  semiconductor  industry.  This slowdown in the  semiconductor  industry has
resulted in reduced  spending for  semiconductor  capital  equipment,  including
automatic test equipment ("ATE") which the Company sells. This industry slowdown
has had and may continue to have a material  adverse effect on product  backlog,
balance sheet and results of  operations.  Therefore,  there can be no assurance
that the operating results will not continue to be materially adversely affected
if downturns or slowdowns in the semiconductor  industry continue or occur again
in the future.

Management of Fluctuations in Our Operating Results
- ---------------------------------------------------

       We have over the last several years experienced significant  fluctuations
in our  operating  results.  In fiscal  1998,  we  generated  net sales of $82.4
million  for the first  quarter  and $22.4  million  for the fourth  quarter,  a
decrease of 73% in our net sales within one fiscal year.  For the second quarter
of fiscal  1999,  the net sales  were  $38.1  million.  Since  1993,  except for
cost-cutting  efforts during the past two years,  we have overall  significantly
increased the scale of our operations in general to support periods of increased
sales levels and expanded  product  offerings  and have  expanded  operations to
address critical infrastructure and other requirements,  including the hiring of
additional  personnel,   significant  investments  in  R&D  to  support  product
development,  our establishment of a joint venture with Innotech Corporation and
numerous  acquisitions.  However,  in the past,  and  particularly  in the three
quarters ended October 31, 1998 and to some extent this fiscal year as discussed
above, we have  experienced  significant  revenue declines and reductions in our
operations.  These  fluctuations  in our  sales  and  operations  have  placed a
considerable  strain  on our  management,  financial,  manufacturing  and  other
resources.  In order to  effectively  deal with the  changes  brought  on by the
cyclical nature of the industry,  we have been required to implement and improve
a variety of highly flexible operating,  financial and other systems, procedures
and controls  capable of expanding or contracting  consistent with our business.
However,  we cannot be certain that any existing or new systems,  procedures  or
controls will be adequate to support  fluctuations in our operations or that our
systems,  procedures and controls will be cost-effective or timely.  Any failure
to  implement,  improve  and expand or contract  such  systems,  procedures  and
controls  efficiently  and at a pace  consistent  with our business could have a
material adverse effect on our business,  financial condition and our results of
operations.

Expansion of Our Product Lines
- ------------------------------

       We are  currently  devoting and intend to continue to devote  significant
resources to the  development  of new products and  technologies.  During fiscal
1999,  we  intend  to  evaluate  these new  products  and to invest  significant
resources in plant and equipment,  leased facilities,  inventory,  personnel and
other costs, to begin or prepare to increase production of these products and to
provide the marketing,  administration and after-sales  service and support,  if
any,  required to service and support these new hardware and software  products.
Accordingly,  we cannot be certain that gross profit margin and inventory levels
will not  continue to be adversely  impacted by continued  delays in new product
introductions  or start-up  costs  associated  with the initial  production  and
installation of these new product lines. These start-up costs include additional
manufacturing  overhead,  additional inventory and warranty reserve requirements
and the  enhancement  of  after-sales  service  and  support  organizations.  In
addition,  the  increases  in  inventory  on hand for new  hardware and software
product  development and customer support  requirements  have increased and will
continue to increase the risk of inventory write-offs. We cannot be certain that
operating  expenses will not increase,  relative to sales, as a result of adding
additional marketing and administrative personnel, among other costs, to support
our additional products. If we are unable to achieve significantly increased net
sales or if sales fall below  expectations,  our operating results will continue
to be  materially  adversely  affected.  We cannot be certain that our net sales
will  increase  or  remain at recent  levels  or that any new  products  will be
successfully commercialized or contribute to revenue growth.

Limited Sources of Supply; Reliance on Our Subcontractors
- ---------------------------------------------------------

       We obtain certain  components,  subassemblies and services  necessary for
the  manufacture  of our testers from a limited  group of  suppliers.  We do not
maintain  long-term  supply  agreements with most of our vendors and we purchase
most of our components and subassemblies through individual purchase orders. The
manufacture  of certain of our  components  and  subassemblies  is an  extremely
complex  process.  We also  rely  on  outside  vendors  to  manufacture  certain
components and subassemblies  and to provide certain services.  We have recently
experienced  and continue to  experience  significant  reliability,  quality and
timeliness  problems with several critical  components  including certain custom
integrated  circuits.   In  addition,  we  and  certain  of  our  subcontractors
periodically  experience significant shortages and delays in delivery of various
components and subassemblies.  We cannot be certain that these or other problems
will  not  continue  to occur  in the  future  with  our  suppliers  or  outside
subcontractors.  Our  reliance on a limited  group of  suppliers  and on outside
subcontractors  involves  several  risks,  including  an  inability to obtain an
adequate supply of required  components,  subassemblies and services and reduced
control over the price, timely delivery,  reliability and quality of components,
subassemblies and services.  Shortages,  delays,  disruptions or terminations of
the  sources  for these  components  and  subassemblies  have  delayed and could
continue to delay  shipments of our systems and new products and could  continue
to have a  material  adverse  effect on our  business,  financial  condition  or
results of operations.  Our continuing  inability to obtain  adequate  yields or
timely  deliveries  or any other  circumstance  that  would  require  us to seek
alternative sources of supply or to manufacture such components internally could
also have a material  adverse  effect on our  business,  financial  condition or
results of operations.  Such delays, shortages and disruptions would also damage
relationships with current and prospective customers and have and could continue
to allow competitors to penetrate such customer  accounts.  We cannot be certain
that  our  internal   manufacturing  capacity  or  that  of  our  suppliers  and
subcontractors will be sufficient to meet customer requirements.

Highly Competitive Industry
- ---------------------------

       The ATE industry is  intensely  competitive.  Because of the  substantial
investment  required to develop test  application  software and  interfaces,  we
believe that once a  semiconductor  manufacturer  has selected a particular  ATE
vendor's tester, the manufacturer is likely to use that tester for a majority of
its testing  requirements for the market life of that  semiconductor and, to the
extent possible,  subsequent  generations of similar products. As a result, once
an ATE customer chooses a system for the testing of a particular  device,  it is
difficult  for  competing  vendors  to  achieve  significant  ATE  sales to such
customer for similar use. Our  inability to penetrate  any large ATE customer or
achieve  significant  sales to any ATE  customer  could have a material  adverse
effect on our business, financial condition or results of operations.

                                       17
<PAGE>

       We face substantial  competition throughout the world, primarily from ATE
manufacturers located in the United States, Europe and Japan, as well as several
of our customers.  Many competitors  have  substantially  greater  financial and
other resources with which to pursue engineering,  manufacturing,  marketing and
distribution of their products.  Certain competitors have recently introduced or
announced new products with certain performance or price  characteristics  equal
or superior to certain  products we  currently  offer.  These  competitors  have
recently  introduced  products that compete  directly  against our products.  We
believe that if the ATE  industry  continues to  consolidate  through  strategic
alliances  or  acquisitions,  we will  continue to face  significant  additional
competition  from larger  competitors  that may offer product lines and services
more  complete  than  ours.  Our  competitors  are  continuing  to  improve  the
performance   of  their   current   products  and  to  introduce  new  products,
enhancements  and new  technologies  that provide improved cost of ownership and
performance characteristics.  New product introductions by our competitors could
cause a  decline  in our  sales or loss of  market  acceptance  of our  existing
products.

       Moreover,  our  business,  financial  condition or results of  operations
could  continue to be  materially  adversely  affected by increased  competitive
pressure and continued intense price-based competition.  We have experienced and
continue to experience significant price competition in the sale of our testers.
In addition,  pricing  pressures  typically  become more intense at the end of a
product's life cycle and as competitors introduce more technologically  advanced
products.  We  believe  that to be  competitive,  we  must  continue  to  expend
significant  financial resources in order to, among other things,  invest in new
product  development  and  enhancements  and to  maintain  customer  service and
support centers worldwide.  We cannot be certain that we will be able to compete
successfully in the future.

Rapid Technological Change; Importance of Timely Product Introduction
- ---------------------------------------------------------------------

       The ATE market is subject to rapid  technological  change. Our ability to
compete in this  market  depends  upon our ability to  successfully  develop and
introduce  new  hardware  and software  products  and  enhancements  and related
software  tools with  greater  features  on a timely and  cost-effective  basis,
including the products under development that we acquired in the EPRO merger and
the  acquisition  of certain  product  lines from  Summit  Design,  Inc.,  Zycad
Corporation  and Heuristic  Physics  Laboratories,  Inc. Our  customers  require
testers and software  products with additional  features and higher  performance
and other capabilities. We are therefore required to enhance the performance and
other  capabilities  of our existing  systems and software  products and related
software tools.  Any success we may have in developing new and enhanced  systems
and software  products  and new  features to our  existing  systems and software
products will depend upon a variety of factors,  including:

     o    product selection;

     o    timely and efficient completion of product design;

     o    implementation of manufacturing and assembly processes;

     o    successful coding and debugging of software;

     o    product performance;

     o    reliability in the field; and

     o    effective sales and marketing.

       Because we must make new product development  commitments well in advance
of sales,  new product  decisions  must  anticipate  both future  demand and the
availability of technology to satisfy that demand.  We cannot be certain that we
will be  successful in selecting,  developing,  manufacturing  and marketing new
hardware and software  products or enhancements  and related software tools. Our
inability to introduce new products and related  software tools that  contribute
significantly  to net sales,  gross margins and net income would have a material
adverse effect on our business,  financial  condition and results of operations.
New product or technology introductions by our competitors could cause a decline
in sales or loss of market acceptance of our existing products.  In addition, if
we introduce new products, existing customers may curtail purchases of the older
products and delay new product  purchases.  Any unanticipated  decline in demand
for our hardware or software products could have a materially  adverse affect on
our business, financial condition or results of operations.

                                       18
<PAGE>

       Significant  delays can occur  between the time we introduce a system and
the time we are able to  produce  that  system  in  volume.  We have in the past
experienced significant delays in the introduction,  volume production and sales
of  our  new  systems  and  related  feature   enhancements  and  are  currently
experiencing  significant delays in the introduction of our VS2000,  Quartet and
Kalos series testers as well as certain  enhancements to our existing SC and DUO
series  testers.  These delays have been  primarily  related to our inability to
successfully  complete product hardware and software engineering within the time
frame originally anticipated, including design errors and redesigns of ICs. As a
result,  certain customers have experienced  significant delays in receiving and
using certain of our testers in  production.  We cannot be certain that these or
additional  difficulties will not continue to arise or that such delays will not
continue to materially adversely affect customer relationships and future sales.
Moreover,  we  cannot  be  certain  that we will  not  encounter  these or other
difficulties that could delay future introductions or volume production or sales
of our systems or enhancements  and related software tools. We have incurred and
may   continue  to  incur   substantial   unanticipated   costs  to  ensure  the
functionality  and  reliability of our testers and to increase  feature sets. If
our systems  continue to have  reliability,  quality or other  problems,  or the
market perceives certain of our products to be feature deficient,  we may suffer
reduced  orders,  higher  manufacturing  costs,  delays in  collecting  accounts
receivable  and higher  service,  support and  warranty  expenses,  or inventory
write-offs,  among other effects.  Our failure to have a competitive  tester and
related  software tools available when required by a semiconductor  manufacturer
could  make it  substantially  more  difficult  for us to sell  testers  to that
manufacturer  for a number of years.  We believe that the continued  acceptance,
volume  production,  timely  delivery  and  customer  satisfaction  of our newer
digital, mixed signal and non-volatile memory testers are of critical importance
to our future  financial  results.  As a result,  our  inability  to correct any
technical,  reliability,  parts shortages or other difficulties  associated with
our systems or to  manufacture  and ship the  systems on a timely  basis to meet
customer   requirements   could  damage  our  relationships   with  current  and
prospective  customers  and would  continue to materially  adversely  affect our
business, financial condition and results of operations.

Customer Concentration; Lengthy Sales Cycle
- -------------------------------------------

       One customer, Spirox Corporation (a distributor in Taiwan), accounted for
43%,  34%,  30% and 25% of our net  sales in the first  half of fiscal  1999 and
fiscal years 1998,  1997, and 1996,  respectively.  Consequently,  our business,
financial  condition  and results of operations  could be  materially  adversely
affected  by the  loss of or any  reduction  in  orders  by  this  or any  other
significant customer,  including losses or reductions due to continuing or other
technical,  manufacturing or reliability problems with our products or continued
slow-downs in the semiconductor industry or in other industries that manufacture
products  utilizing  semiconductors.  Our ability to maintain or increase  sales
levels will depend  upon:

     o    our ability to obtain orders from existing and new customers;

     o    our  ability  to  manufacture  system on a timely  and  cost-effective
          basis;

     o    our  ability to  complete  the  development  of our new  hardware  and
          software products;

     o    our customers' financial condition and success;

     o    general economic conditions; and

     o    our ability to meet increasingly  stringent  customer  performance and
          other requirements and shipment delivery dates.

       Sales of our systems  depend in part upon the  decision of  semiconductor
manufacturers  to  develop  and  manufacture  new  semiconductor  devices  or to
increase  manufacturing  capacity. As a result, sales of our testers are subject
to a variety of factors we cannot control. In addition, the decision to purchase
a tester  generally  involves a  significant  commitment  of  capital,  with the
attendant delays frequently  associated with significant  capital  expenditures.
For these and other reasons,  our systems have lengthy sales cycles during which
we may  expend  substantial  funds  and  management  effort  to  secure  a sale,
subjecting  us to a number of  significant  risks.  We cannot be certain that we
will be able to maintain or increase  net sales in the future or that we will be
able to retain existing customers or attract new ones.

                                       19
<PAGE>

Risks Associated with Acquisitions
- ----------------------------------

       We have developed in significant part through mergers and acquisitions of
other  companies and  businesses.  We intend in the future to pursue  additional
acquisitions of complementary product lines, technologies and businesses. We may
have to issue debt or equity  securities to pay for future  acquisitions,  which
could be  dilutive.  We have also  incurred  and may  continue to incur  certain
liabilities or other expenses in connection  with  acquisitions,  which have and
could continue to materially adversely affect our business,  financial condition
and  results  of  operations.  Although  we believe  we have  accounted  for our
acquisitions  properly,  the U.S. Securities and Exchange Commission (the "SEC")
has recently been  reviewing more closely the  accounting  for  acquisitions  by
companies,  particularly  in the area of  "in-process"  research and development
costs. If we are required by the SEC to restate any charge that we recognized in
an  acquisition  so far,  that  could  result in a lesser  charge to income  and
increased  amortization expense, which could also have a material adverse effect
on our business, financial condition and results of operations.

       In addition, acquisitions involve numerous other risks, including:

     o    difficulties assimilating the operations, personnel, technologies and
          products of the acquired companies;

     o    diversion of our management's attention from other business concerns;

     o    risks of entering markets in which we have no or limited experience;
          and

     o    the potential loss of key employees of the acquired companies.

       For these reasons,  we cannot be certain what effect future  acquisitions
may have on our business, financial condition and results of operations.

Changes in Financial Accounting Standards and Accounting Estimates
- ------------------------------------------------------------------

       We prepare our financial  statements to conform with  generally  accepted
accounting  principles  ("GAAP").  GAAP are  subject  to  interpretation  by the
American Institute of Certified Public  Accountants,  the SEC and various bodies
formed to interpret  and create  appropriate  accounting  policies.  A change in
those policies can have a significant  effect on our reported  results,  and may
even  affect  our  reporting  of  transactions  completed  before  a  change  is
announced.  Accounting  policies  affecting  many other aspects of our business,
including  rules  relating to purchase and  pooling-of-interests  accounting for
business  combinations,  employee stock purchase plans and stock options grants,
have recently  been revised or are under  review.  Changes to those rules or the
questioning  of  current  practices  may have a material  adverse  effect on our
reported financial results or on the way we conduct our business.

       In addition,  our preparation of financial  statements in accordance with
GAAP requires that we make  estimates and  assumptions  that affect the recorded
amounts of assets and liabilities, disclosure of those assets and liabilities at
the date of the financial statements and the recorded amounts of expenses during
the reporting period. A change in the facts and circumstances  surrounding those
estimates  could result in a change to our estimates and could impact our future
operating results.

Dependence on Key Personnel
- ---------------------------

       Our future  operating  results  depend  substantially  upon the continued
service of our executive  officers and key personnel,  none of whom are bound by
an employment or  non-competition  agreement.  Our future operating results also
depend in  significant  part upon our  ability to attract  and retain  qualified
management, manufacturing,  technical, engineering, marketing, sales and support
personnel.  Competition  for such  personnel  is intense,  and we cannot  ensure
success in attracting or retaining such  personnel.  There may be only a limited
number of persons with the requisite  skills to serve in these  positions and it
may be  increasingly  difficult  for us to hire such  personnel  over time.  Our
business,  financial  condition  and results of  operations  could be materially
adversely  affected by the loss of any of our key  employees,  by the failure of
any key employee to perform in his or her current position,  or by our inability
to attract and retain skilled employees.

                                       20
<PAGE>

Transition in Our Executive Management
- --------------------------------------

       We have experienced several transitions in executive management in recent
years. In conjunction with the departure in December 1998 of our former chairman
and chief executive officer,  our Board of Directors appointed David A. Ranhoff,
executive vice president,  and Dennis P. Wolf,  executive vice president,  chief
financial  officer and secretary,  jointly to the office of the  president.  The
Board also named a new chairman, Dr. William Howard, Jr., and began a search for
a new chief executive  officer.  Mr. Wolf joined us as senior vice president and
chief  financial  officer in March 1998 after the December 1997 departure of the
Company's  previous  chief  financial  officer.  These  transitions  have placed
significant  demands on our operational,  administrative and financial staff and
we  anticipate  that these  demands will increase in the near term. We cannot be
certain that such  transitions  will not have a material  adverse  effect on our
business,  financial  condition  and  results of  operations,  on the way we are
perceived by the market or on the price of our common stock.

International Sales
- -------------------

       International  sales accounted for approximately 74%, 69%, 70% and 67% of
our total net sales for the first  half of fiscal  1999 and fiscal  years  1998,
1997 and 1996, respectively. As a result, we anticipate that international sales
will continue to account for a significant portion of our total net sales in the
foreseeable  future.  These  international  sales will continue to be subject to
certain risks, including:

     o    changes in regulatory requirements;

     o    tariffs and other barriers;

     o    political and economic instability;

     o    an outbreak of hostilities;

     o    integration of foreign operations of acquired businesses;

     o    foreign currency exchange rate fluctuations;

     o    difficulties  with  distributors,  joint  venture  partners,  original
          equipment manufacturers, foreign subsidiaries and branch operations;

     o    potentially adverse tax consequences; and

     o    the possibility of difficulty in accounts receivable collection.

       We are also  subject  to the  risks  associated  with the  imposition  of
domestic  and  foreign  legislation  and  regulations  relating to the import or
export of  semiconductor  equipment.  We cannot  predict  whether the import and
export of our products will be subject to quotas, duties, taxes or other charges
or restrictions imposed by the United States or any other country in the future.
Any of these  factors  or the  adoption  of  restrictive  policies  could have a
material  adverse  effect on our  business,  financial  condition  or results of
operations.  Net sales to the Asia Pacific  region  accounted for  approximately
66%,  60%,  66% and 58% of our total net sales for the first half of fiscal 1999
and for the fiscal years 1998,  1997 and 1996,  and thus demand for our products
is subject to the risk of economic instability in that region and could continue
to be  materially  adversely  affected.  Countries in the Asia  Pacific  region,
including  Korea  and  Japan,  have  recently  experienced  weaknesses  in their
currency,  banking  and equity  markets.  These  weaknesses  could  continue  to
adversely  affect demand for our products,  the  availability  and supply of our
product  components,  and our  consolidated  results of operations.  The current
Asian  financial  crisis  has  contributed  to a  widespread  uncertainty  and a
slowdown in the  semiconductor  industry.  This slowdown has resulted in reduced
spending on semiconductor capital equipment, including ATE, and has had, and may
continue to have,  a material  adverse  effect on our product  backlog,  balance
sheet and results of operations.

       We do not expect that the  introduction and the use of the Euro will have
a material  adverse  effect on our business,  financial  condition or results of
operations.

Proprietary Rights
- ------------------

       We attempt to protect our  intellectual  property rights through patents,
copyrights,  trademarks,  maintenance  of  trade  secrets  and  other  measures,
including  entering  into  confidentiality  agreements.  However,  we  cannot be
certain  that others will not  independently  develop  substantially  equivalent
intellectual  property  or that we can  meaningfully  protect  our  intellectual
property. Nor can we be certain that our patents will not be invalidated, deemed
unenforceable, circumvented or challenged, or that the rights granted thereunder
will  provide  us with  competitive  advantages,  or that any of our  pending or
future patent  applications  will be issued with claims of the scope we seek, if
at all.  Furthermore,  we cannot be certain that others will not develop similar
products,  duplicate our products or design around our patents,  or that foreign
intellectual  property laws or agreements  into which we've entered will protect
our  intellectual   property  rights.   Inability  or  failure  to  protect  our
intellectual  property  rights  could have a material  adverse  effect  upon our
business,  financial condition and results of operations.  We have been involved
in  extensive,   expensive  and   time-consuming   reviews  of,  and  litigation
concerning,  patent  infringement  claims.  In  addition,  we have at times been
notified that we may be infringing intellectual property rights of third parties
and we expect to continue to receive notice of such claims in the future.

       In July, 1998, inTEST IP Corporation  ("inTEST")  alleged in writing that
one of our products is  purportedly  infringing a patent held by inTEST.  We may
also be obligated to other third parties  relating to this  allegation.  We have
completed  initial  investigation  into  the  allegation.  Based  in part on the
opinion of outside  counsel,  we believe  we have  meritorious  defenses  to the
claims.  However,  we cannot be  certain of success  in  defending  this  patent
infringement  claim or claims for  indemnification  resulting from  infringement
claims.

       Certain of our customers have received  notices from Mr. Jerome  Lemelson
alleging that the  manufacture of  semiconductor  products  and/or the equipment
used to manufacture  semiconductor  products infringes certain patents issued to
Mr. Lemelson. We were notified by a customer in 1990 and by a different customer
in late 1994 that we may be  obligated  to  defend  or  settle  claims  that our
products infringe Mr. Lemelson's patents,  and that if it is determined that the
customer  infringes  Mr.  Lemelson's  patents,  such  customer  intends  to seek
indemnification  from us for damages  and other  related  expenses.  We have not
received further communications from such customers regarding these matters.

       We cannot be certain of success  in  defending  current or future  patent
infringement  claims or claims for  indemnification  resulting from infringement
claims.  Our business,  financial  condition and results of operations  could be
materially  adversely affected if we must pay damages to a third party or suffer
injunction  or if we expend  significant  amounts in defending  any such action,
regardless of the outcome.  With respect to any claims,  we may seek to obtain a
license  under the third  party's  intellectual  property  rights.  We cannot be
certain,  however,  that the third  party will grant us a license on  reasonable
terms or at all. We could decide,  in the alternative,  to litigate such claims.
Litigation on such matters may be extremely  expensive and time  consuming,  and
could materially  adversely affect our business,  financial condition or results
of operations, regardless of the outcome.

Future Capital Needs; Leverage
- ------------------------------

       Developing and  manufacturing  new ATE systems and enhancements is highly
capital  intensive.  In  order  to be  competitive,  we  must  make  significant
investments in capital equipment,  expansion of operations,  systems, procedures
and controls,  research and development and worldwide training, customer service
and  support,  among many  other  items.  We may be unable to obtain  additional
financing in the future on acceptable  terms,  or at all. In connection with our
issuance in September 1997 of  convertible  promissory  notes (the "Notes"),  we
currently  have  $106  million  of  indebtedness  which  resulted  in a ratio of
long-term  debt  to  total  long-term   capitalization  at  April  30,  1999  of
approximately  41%. As a result,  our  principal and interest  obligations  have
increased  substantially.  The degree to which we are leveraged could materially
adversely   affect  our  ability  to  obtain   financing  for  working  capital,
acquisitions  or other  purposes and could make our business more  vulnerable to
industry downturns and competitive  pressures.  Our ability to meet debt service
obligations will be dependent upon our future performance, which will be subject
to financial, business and other factors affecting our operations, many of which
are  beyond  our  control.  If we  raise  additional  funds  by  issuing  equity
securities,  our stockholders  could be significantly  diluted.


                                       22

We may  exchange  Notes  for  shares of our  common  stock or may  refinance  or
exchange  the  Notes,  which may also  dilute our  stockholders  and may make it
difficult for us to obtain additional future financing, if needed.

       If we are  unable  to  obtain  adequate  funds,  we may  be  required  to
restructure or refinance our debt or to delay,  scale back or eliminate  certain
of our research and development,  acquisition or manufacturing  programs. We may
also need to obtain funds  through  arrangements  with partners or others and we
may be required to relinquish rights to certain of our technologies or potential
products or other assets.

Year 2000 Readiness Disclosure
- ------------------------------

       The "Year  2000" issue  results  from the use in  computer  hardware  and
software of two digits  rather than four digits to define the  applicable  year.
When computer  systems must process dates both before and after January 1, 2000,
two-digit year "fields" may create processing  ambiguities that can cause errors
and system failures. The results of these errors may range from minor undetected
errors to complete shutdown of an affected system.  These errors or failures may
have  limited  effects,  or the  effects  may be  widespread,  depending  on the
computer chip, system or software, and its location and function. The effects of
the Year 2000 problem are exacerbated because of the interdependence of computer
and  telecommunications  systems in the United States and  throughout the world.
Because  of this  interdependence,  the  failure  of one  system may lead to the
failure of many other systems even though the other systems are themselves "Year
2000 compliant."

       Our Board of Directors has reviewed the Year 2000 issue  generally and as
it may affect our business  activity  specifically.  We are  implementing a Year
2000 plan (the  "Plan")  which is  designed to cover all of our  activities  and
which  is  monitored  by the  Board of  Directors.  We will  modify  the Plan as
circumstances change. Under the Plan, we are using a five-phase  methodology for
addressing  the  issue.  The  phases  are  Awareness,  Assessment,   Renovation,
Validation and Implementation.

       The  Awareness  phase  consisted  of defining  the Year 2000  problem and
gaining   executive   level  support  and  sponsorship  for  addressing  it.  We
established a Year 2000 program team and created an overall strategy. During the
Assessment phase, we inventoried all internal systems, products and supply chain
partners and  prioritized  each for  renovation.  We believe we have completed a
majority of the Awareness and Assessment  phases;  however,  we will continue to
work in these areas as we complete  our  assessment  of  existing  supply  chain
partners and enter into new supply chain relationships in the ordinary course of
business. Renovation consists of converting, replacing, upgrading or eliminating
systems   that  have  Year  2000   problems.   We  have  begun   renovation   on
mission-critical systems and have completed for all but two systems by April 30,
1999.  The  remaining  two  mission-critical   systems  are  now  scheduled  for
completion  of renovation by October  1999.  Validation  involves  ensuring that
hardware and software  fixes will work properly in 1999 and beyond and can occur
both before and after implementation. We began the Validation phase in late 1998
and will  continue  through June 1999 to allow for thorough  testing  before the
Year 2000.  Implementation  is the  installation of Year 2000 ready hardware and
software components in a live environment.

       The impact of Year 2000  issues on our  business  will depend not only on
corrective  actions  that we  take,  but also on the way Year  2000  issues  are
addressed by  governmental  agencies,  businesses  and other third  parties that
provide us with  services or data or receive  services or data from us, or whose
financial condition or operational capability is important to us. To reduce this
exposure,   we  have  an  ongoing   process  of   identifying   and   contacting
mission-critical  third party  vendors and other  significant  third  parties to
determine their Year 2000 plans and target dates. Risks associated with any such
third parties  located  outside the United States may be higher insofar as it is
generally  believed that non-U.S.  businesses  may not be addressing  their Year
2000  issues  on as  timely  a basis  as U.S.  businesses.  Notwithstanding  our
efforts, we cannot be certain that we,  mission-critical  third party vendors or
other significant third parties will adequately address their Year 2000 issues.

       We  are   developing   contingency   plans   in  the   event   that   we,
mission-critical  third party vendors or other significant third parties fail to
adequately address Year 2000 issues.  Such plans principally involve identifying
alternative  vendors or  internal  remediation.  We cannot  ensure that any such
plans will fully mitigate any such failures or problems.  Furthermore, there may
be certain mission-critical third parties, such as utilities,  telecommunication

                                       23
<PAGE>

companies, or material vendors for which alternative arrangements or sources are
limited or unavailable.

       Although  it  is  difficult  for  us  to  estimate  the  total  costs  of
implementing  the  Plan,  our  current  estimate  is  that  such  costs  will be
approximately $2.5 million through October 1999 and beyond. However, although we
believe that our estimates are reasonable, we cannot be certain, for the reasons
stated in the next  paragraph,  that the actual costs of  implementing  the Plan
will not differ  materially from the estimated  costs. We have incurred costs of
approximately $1.5 million through April 30, 1999 in connection with the Plan. A
significant  portion of total  Year 2000  project  expenses  is  represented  by
existing staff that have been redeployed to this project. We do not believe that
the  redeployment  of existing staff will have a material  adverse effect on our
business,  results  of  operations  or  financial  position.  Nor  do we  expect
incremental  expenses  related  to the Year 2000  project to  materially  impact
operating results in any one period.

       For a number of reasons,  we cannot  predict or  quantify  the extent and
magnitude of the Year 2000 problem as it will affect our business, either before
or for some period after January 1, 2000. Among the most important  reasons are:

     o    lack of control  over systems  used by third  parties  critical to our
          operation;

     o    dependence  on third  party  software  vendors  to  deliver  Year 2000
          upgrades in a timely manner;

     o    complexity of testing  inter-connected  networks and applications that
          depend on third party networks; and

     o    the uncertainty surrounding how others will deal with liability issues
          raised by Year 2000 related failures.

       For example, we cannot be certain that systems used by third parties will
be Year 2000 ready by January 1, 2000,  or by some  earlier  date,  so as not to
create a material disruption to our business.  Moreover,  the estimated costs of
implementing  the Plan do not take into account the costs, if any, that might be
incurred  as a result of Year  2000-related  failures  that  occur  despite  our
implementation of the Plan.

       Although we are not aware of any material  operational  issues associated
with preparing our internal systems for the Year 2000 or of material issues with
respect to the  adequacy  of  mission-critical  third party  systems,  we cannot
ensure that we will not experience material  unanticipated negative consequences
and/or material costs caused by undetected  errors or defects in such systems or
by our failure to adequately  prepare for the results of such errors or defects,
including  the  costs  of  related  litigation,  if  any.  The  impact  of  such
consequences  could have a material  adverse  effect on our business,  financial
condition or results of operations.

Volatility of Our Stock Price
- -----------------------------

       We believe that factors such as announcements of developments  related to
our business,  fluctuations  in our  financial  results,  general  conditions or
developments in the semiconductor and capital equipment industry and the general
economy,   sales  or  purchases   of  our  common  stock  in  the   marketplace,
announcements of our  technological  innovations or new products or enhancements
or those of our  competitors,  developments  in  patents  or other  intellectual
property rights, developments in our relationships with customers and suppliers,
or a  shortfall  or changes in  revenue,  gross  margins  or  earnings  or other
financial  results from analysts'  expectations or an outbreak of hostilities or
natural  disasters,  could  continue  to cause the price of our common  stock to
fluctuate,  perhaps substantially.  In recent years the stock market in general,
and the market  for  shares of small  capitalization  companies  in  particular,
including ours, have experienced  extreme price  fluctuations,  which have often
been unrelated to the operating performance of affected companies.  For example,
in fiscal 1997,  the price of our common stock ranged from a high of $55.00 to a
low of $13.75.  In fiscal 1998, the price of our common stock ranged from a high
of $35.25 to a low of $9.31 and during the first six months of fiscal 1999,  the
price of our common stock  ranged from a high of $22.41 to a low of $20.85.  The
market   price  of  our  common   stock  is  likely  to  continue  to  fluctuate
significantly   in  the  future,   including   fluctuations   unrelated  to  our
performance.

                                       24

Effects of Certain Anti-Takeover Provisions
- -------------------------------------------

       Certain   provisions   of  our  Amended  and  Restated   Certificate   of
Incorporation,  shareholders  rights plan, equity incentive plans, Bylaws and of
Delaware law may discourage certain transactions involving a change in corporate
control.  In addition to the foregoing,  our classified board of directors,  the
shareholdings  of our  officers,  directors  and persons or entities that may be
deemed affiliates,  the adoption of a shareholder rights plan and the ability of
our Board of Directors to issue "blank check"  preferred  stock without  further
stockholder approval could have the effect of delaying,  deferring or preventing
a third party to acquire us and may adversely affect the voting and other rights
of holders of our common stock.

(the  "Amendment")  by and between  SILICON  VALLEY BANK  ("Agent") as Servicing
Agent  and a Bank and BANK OF  HAWAII  ("BofH";  SVB and  BofH are  referred  to
individually  herein as "Bank",  and  collectively  as the "Banks") and CREDENCE
SYSTEMS  CORPORATION,  a Delaware  corporation  ("Credence"),  Credence Korea, a
Korean   corporation,   and  Credence  Systems  K.K.,  a  Japanese   corporation
(individually a "Borrower" and collectively, the "Borrowers").

                                    RECITALS

         Borrower and Bank are parties to that certain Loan  Agreement  dated as
of July 26, 1996, and amended by that certain  Amendment to Loan Agreement dated
as of July 25, 1997 and that  certain  Amendment to Loan  Agreement  dated as of
July 24, 1998 (the  "Agreement").  The parties  desire to amend the Agreement in
accordance with the terms of this Amendment.

         NOW, THEREFORE, the parties agree as follows:

         1. The following definitions in Section 1.1 are amended and replaced in
         their entirety to read as follows:

                  "Total  Liabilities"  means at any date as of which the amount
thereof shall be determined,  all  obligations  that should,  in accordance with
GAAP  be  classified  as  liabilities  on  the  consolidated  balance  sheet  of
Borrowers, including in any event all Indebtedness.

                  "Tangible Net Worth" means, at any date as of which the amount
thereof shall be determined,  the consolidated  total assets of Borrowers minus,
without  duplication,  (i) the sum of any amounts  attributable to (a) goodwill,
(b)  intangible  items such as unamortized  debt discount and expense,  patents,
trade and service  marks and names,  copyrights  and  research  and  development
expenses except prepaid expenses, and (c) all reserves not already deducted from
assets, and (ii) Total Liabilities."

     2. The  references in Sections  2.1(c) and 2.1(d) to "150 basis points" are
hereby amended to read "200 basis points".

     3. Section 5.8 is hereby  deleted in its  entirety  and  replaced  with the
following:

     "5.8 Debt-Tangible Net Worth Ratio.  Maintain,  on a consolidated basis, as
of the last day of each fiscal quarter, a ratio of Total Liabilities,  excluding
Subordinated Debt, to Tangible Net Worth, of not more tha 1.0 to 1.0."

     4. Section 5.9 is hereby  deleted in its  entirety  and  replaced  with the
following:

     "5.9 Tangible Net Worth.  Maintain, on a consolidated basis, as of the last
day of each fiscal quarter,  a Tangible Net Worth plus  Subordinated Debt of not
less than Two Hundred Twenty Million Dollars ($220,000,000)."

     5.  Section 5.10 is hereby  deleted in its  entirety and replaced  with the
following:

     "5. 10  Profitability.  On a consolidated  basis,  sustain from  continuous
operations  excluding  noncash events,  a loss of no more than Thirteen  Million
Dollars  ($13,000,000)  for each of the fiscal quarters ending on April 30, 1999
and July 31,  1999,  provided  that  Borrower  may not sustain  from  continuous
operations, excluding noncash events, a loss of more than Twenty Million Dollars
($20,000,000)  in the  aggregate for both quarters  combined.  Thereafter,  on a
consolidated basis, have a minimum continuous  operations net profit of at least
One Dollar ($1.00) for each fiscal year."

                                       1


                                       29
<PAGE>

     6. Bank waives Borrower's  obligations to comply with Section 5.10 for both
the quarter and the year  ending on October 31,  1998.  Bank does not waive such
obligations  for any other dates or any other failure by Borrower to perform its
obligations  under the Loan  Documents.  This waiver is not a continuing  waiver
with  respect to any  failure to perform any  obligation  after the date of this
Amendment.

     7. On the signature  page of the Agreement the reference to Silicon  Valley
Bank's Maximum Commitment Amount:  $15,000,000 (37.5%) is hereby amended to read
$20,000,000 (50.0%).

     8. On the signature page of the Agreement the reference to Bank of Hawaii's
Maximum  Commitment  Amount:  $25,000,000  (62.5%)  is  hereby  amended  to read
$20,000,000 (50.0%).

     9. The  attached  Exhibit C is hereby added and  incorporated  by reference
into the Agreement.

     10. As a condition  to the  effectiveness  of this  Amendment,  Banks shall
receive a fee of Twenty-Five  Thousand Dollars ($25,000),  payable upon the date
hereof,  plus all Bank Expenses  incurred in connection  with the preparation of
this Amendment.

     11. As a condition to the effectiveness of this Amendment,  Bank shall have
received, in form and substance satisfactory to Bank, the following:

          (a)  resolutions  by  the  Borrowers  authorizing  the  execution  and
     delivery of this Amendment; and

          (b) such other  documents,  and completion of such other  matters,  as
     Bank may reasonably deem necessary or appropriate.

     12. Unless otherwise defined, all capitalized terms in this Amendment shall
be as defined in the Agreement. Except as amended, the Agreement remains in full
force and effect.

     13.  Borrower   represents  and  warrants  that  the   Representations  and
Warranties  contained  in the  Agreement  are true and correct as of the date of
this Amendment, and that no Event of Default has occurred and is continuing.

     14. This Amendment may be executed in two or more counterparts, each of
which shall be deemed an original,  but all of which together  shall  constitute
one instrument.

                                       2

Mr. David A. Ranhoff

Dear David:

We are pleased to inform you that the Company's  Board of Directors has approved
a  special  severance  benefit  program  for you.  The  purpose  of this  letter
agreement is to set forth the terms and  conditions of your  severance  benefits
and to explain the limitations that will govern their overall value.

Your severance  package will become  payable  should the Company  terminate your
employment,  or should you  otherwise  resign from the  Company,  under  certain
circumstances  following a  substantial  change in  ownership  or control of the
Company or upon the appointment of a new permanent Chief Executive  Officer.  To
understand the full scope of your benefits, you should familiarize yourself with
the definitional  provisions of Part One of this letter agreement.  The benefits
comprising  your  severance  package  are  detailed  in Part  Two,  and  certain
restrictions  applicable to your benefits are specified in Part Three. Part Four
sets forth the dollar  limitation which will govern your total severance package
in the event your  termination  occurs in connection with a change in control or
ownership of the Company.  Part Five deals with ancillary matters affecting your
severance arrangement.

                             Part One - DEFINITIONS
                             ----------------------

For purposes of this letter  agreement,  the  following  definitions  will be in
effect:

Average  Compensation  means the  average of your W-2 wages from the Company for
the five  (5)  calendar  years  (or  such  fewer  number  of  calendar  years of
employment with the Company) completed immediately prior to the calendar year in
which a Change in  Control  is  effected.  Any W-2  wages for a partial  year of
employment will be annualized, in accordance with the frequency which such wages
are  paid  during  such  partial   year,   before   inclusion  in  your  Average
Compensation.

Base Salary means the monthly rate of base salary in effect for you  immediately
prior to the Change in Control or Change in Management  (as  applicable)  or (if
greater)  the  monthly  rate  of  base  salary  in  effect  at the  time of your
Involuntary Termination.

Board means the Company's Board of Directors.

                           (ii) any stockholder-approved sale, transfer or other

                  assets in complete liquidation or dissolution of the Company;

                           (iii) the acquisition, directly or indirectly, by any

                  tender  or  exchange  offer  made  directly  to the  Company's

                           (iv) a change in the  composition of the Board over a
                  period of thirty-six (36) consecutive months or less such that
                  a majority of the Board  members  ceases,  by reason of one or
                  more contested elections for Board membership, to be comprised
                  of  individuals   who  either  (A)  have  been  Board  members
                  continuously  since the  beginning  of such period or (B) have
                  been elected or nominated for election as Board members during
                  such  period  by at  least a  majority  of the  Board  members
                  described  in clause  (A) who were still in office at the time

Fair Market Value means,  with respect to the shares of Common Stock  subject to
any of your Options,  the closing selling price per share of Common Stock on the
date in  question,  as such price is reported  by the  National  Association  of
Securities Dealers on the Nasdaq National Market. If there is no closing selling
price  reported  for the  Common  Stock on the date in  question,  then the Fair
Market Value will be the closing  selling price on the last  preceding  date for
which such report exists.

Health Care Coverage  means the continued  health care coverage to which you and
your eligible  dependents may be entitled during any Salary  Continuation Period
in effect for you under this letter agreement.

Involuntary Termination means (i) the involuntary termination of your employment
with the  Company  other  than a  Termination  for Cause or (ii) your  voluntary
resignation  within ninety (90) days following (A) a material  reduction in your
duties and responsibilities as an Executive Vice President of the Company or (B)
a material  reduction  in your level of cash  compensation  (rate of Base Salary
plus target  bonus  under any  corporate-performance  based  bonus or  incentive
programs).

In no event shall any of the  following  constitute  grounds  for a  resignation
qualifying as an Involuntary Termination under this letter agreement:

         - a change or other alteration in your duties which occurs by reason of
the Company's  conversion from a public company into a subsidiary or division of
the  acquiring  entity in a Change in  Control  transaction  but which  does not
otherwise materially affect your day-to-day functions; or

         - a general  reduction  in the level of base  salary or target  bonuses
payable to the  executive  officers  of the  Company  which is applied to all or
substantially all of the Company's  executive officers in connection with a cost
reduction program.

In addition, an Involuntary Termination will not be deemed to occur in the event
your  employment  terminates  by  reason  of  your  death  or  Disability  or  a
Termination  for  Cause or in the  event  the  acquiring  entity  in a Change in
Control  transaction offers you a position  comparable to your position with the
Company immediately prior to the Change in Control and at substantially the same
level of cash compensation.

                                                                               4

Life  Insurance  Coverage  means  the  continued  coverage  to which  you may be
entitled  under the Company's  group-term  and executive  life  insurance  plans
during  any  Salary  Continuation  Period in effect  for you under  this  letter
agreement.

Option means any option  granted to you under the Plan which is  outstanding  at
the time of the Change in Control or Change in  Management  (as  applicable)  or
upon your  subsequent  Involuntary  Termination.  In connection with a Change in
Control,  your  Options  will be divided  into two (2)  separate  categories  as
follows:

          Acquisition-Accelerated    Options:   any   outstanding   Option   (or
     installment  thereof)  which  automatically  accelerates,  pursuant  to the
     acceleration  provisions of the agreement  evidencing  that Option,  upon a
     Change in Control.

          Severance-Accelerated  Options: any outstanding Option (or installment
     thereof) which, pursuant to Part Two of this letter agreement,  accelerates
     upon your Involuntary Termination following the Change in Control.

Option  Parachute  Payment  means,  with respect to any  Acquisition-Accelerated
Option or any Severance-Accelerated Option, the portion of that Option deemed to
be a parachute  payment  under Code Section  280G and the  Treasury  Regulations
issued thereunder.  The portion of such Option which is categorized as an Option
Parachute Payment will be calculated in accordance with the valuation provisions
established under Code Section 280G and the applicable Treasury  Regulations and
will  include an  appropriate  dollar  adjustment  to reflect  the lapse of your
obligation  to remain in the  Company's  employ as a condition to the vesting of
the accelerated  installment.  In no event,  however,  will the Option Parachute
Payment    attributable    to    any    Acquisition-Accelerated     Option    or
Severance-Accelerated Option (or accelerated installment) exceed the spread (the
excess of the Fair Market Value of the accelerated option shares over the option
exercise price payable for those shares) existing at the time of acceleration.

Other Parachute  Payment means any payment in the nature of compensation  (other
than the  benefits  to which you become  entitled  under Part Two of this letter
agreement)  which are made to you in  connection  with the Change in Control and
which  accordingly  qualify as  parachute  payments  within the  meaning of Code
Section 280G(b)(2) and the Treasury  Regulations  issued thereunder.  Your Other
Parachute Payment will include (without limitation) the Present Value,  measured
as of  the  Change  in  Control,  of  the  aggregate  Option  Parachute  Payment
attributable to your Acquisition-Accelerated Options (if any).

Parachute  Payment  means any payment or benefit  provided you under Part Two of
this letter  agreement in  connection  with a Change in Control  (other than the
Option Parachute  Payment  attributable to your  Severance-Accelerated  Options)

which is deemed to  constitute  a parachute  payment  within the meaning of Code
Section 280G(b)(2) and the Treasury Regulations issued thereunder.

Plan means (i) the Company's 1993 Stock Option Plan, as amended or restated from
time  to  time,  and  (ii)  any  successor  stock  incentive  plan  subsequently
implemented by the Company.

Present  Value  means  the  value,  determined  as of the date of the  Change in
Control,  of any  payment  in the  nature of  compensation  to which you  become
entitled in connection with the Change in Control or your subsequent Involuntary
Termination,   including  (without  limitation)  the  Option  Parachute  Payment
attributable to your Severance-Acceleration  Options, the additional benefits to
which you become entitled under Part Two of this letter agreement and the Option
Parachute  Payment  attributable to your  Acquisition-Accelerated  Options.  The
Present Value of each such payment will be  determined  in  accordance  with the
provisions  of Code Section  280G(d)(4),  utilizing a discount rate equal to one
hundred twenty  percent  (120%) of the applicable  federal rate in effect at the
time of such  determination,  compounded  semi-annually to the effective date of
the Change in Control.

Salary  Continuation  Period means the period for which the payment of your Base
Salary  may,  pursuant  to  Part  Two of this  letter  agreement,  be  continued
following  an  Involuntary  Termination  of your  employment  within a specified
period  following a Change in Control or Change in Management  (as  applicable).

Termination for Cause means the Company's termination of your employment for any
of the following reasons: (i) your commission of any act of fraud,  embezzlement
or dishonesty,  (ii) your  unauthorized use or disclosure of any confidential or
proprietary  information of the Company, (iii) any intentional misconduct by you
which has a materially  adverse effect upon the Company's business or reputation
or (iv) your  continued  failure  to perform  the major  duties,  functions  and
responsibilities  of your position  after you have received  written notice from
the Company identifying the deficiencies in your performance and have been given
a reasonable opportunity to cure those deficiencies, if curable.

                          Part Two - SEVERANCE BENEFITS
                          -----------------------------

Should your  employment  with the Company  terminate by reason of an Involuntary
Termination  within  twelve (12)  months  after a Change in Control or Change in
Management,  then you will become  entitled to receive  the  severance  benefits
provided  under this Part Two.  However,  those  benefits will be subject to the
restrictive covenants of Part Three of this letter agreement and will be in lieu
of all other  severance  benefits to which you might  otherwise be entitled upon
such termination of your employment. In addition, any severance benefits paid to
you in connection with an Involuntary  Termination following a Change in Control
will be subject to the dollar limitation of Part Four.

                                                                               6

1.       Accelerated Vesting.

A  portion  of each  outstanding  Option  which  you  hold  at the  time of your
Involuntary  Termination,  to the extent not otherwise  exercisable  for all the
shares  of  Common  Stock  subject  to  that  Option,  will  immediately  become
exercisable on an  accelerated  basis and may be exercised for any or all of the
shares  subject  to  that  accelerated  portion  until  the  earlier  of (i) the
expiration  of the  option  term or (ii) the end of the three  (3)-month  period
following the date of your Involuntary Termination.  The number of option shares
which  shall  vest and  become  exercisable  upon such an  accelerated  basis in
connection  with the  Involuntary  Termination  shall be equal to the  number of
shares for which the Option  would have become  exercisable  under the  Exercise
Schedule in effect for that Option had you remained in the Company's  employ for
an  additional  twelve  (12) month  period  after the  Involuntary  Termination.
However,  to the extent any Option is not  exercisable for one or more shares at
the  time of  your  Involuntary  Termination,  after  taking  into  account  the
acceleration  provided  under  this  paragraph,   the  Option  will  immediately
terminate with respect to those shares.

2.       Severance Payment.

You will be entitled to salary continuation  payments at your applicable rate of
Base Salary for a Salary Continuation Period of twelve (12) months. These salary
continuation  payments  will be made to you in  accordance  with  the  Company's
normal payroll practices and will be subject to the Company's  collection of all
applicable federal and state income and employment withholding taxes.

3.       Health Care Coverage.

Should you elect continued health care coverage under the Company's medical plan
pursuant to your rights under Code  Section  4980B  ("COBRA"),  the Company will
provide  such  COBRA  coverage,   without  charge,  to  you  and  your  eligible
dependents.  Such  Company-paid  coverage will continue until the earlier of (i)
the  expiration  of your  Salary  Continuation  Period or (ii) the first date on
which you are covered under another  employer's  health benefit  program without
exclusion for any pre-existing  medical  condition.  Any additional  health care
coverage to which you and your  dependents may be entitled under COBRA following
the period of such Company-paid coverage will be at your sole cost and expense.

4.       Life Insurance Coverage.

You  will  be  entitled  to  Life  Insurance  Coverage  through  your  continued
participation  in the Company's  group term and executive life  insurance  plans
following  your  Involuntary  Termination,  and the Company  will pay the entire
premium charged for such continued Life Insurance  Coverage.  Such  Company-paid
coverage  will continue  until the earlier of (i) the  expiration of your Salary
Continuation  Period  or (ii) the  first  date on which  you are  provided  with

                                       38
<PAGE>
                                                                               7

comparable coverage under another employer's life insurance plan.  However,  you
will be  responsible  for the  satisfaction  of any  income and  employment  tax
liability  attributable  to your  Company-paid  Life  Insurance  Coverage.

Your payments and benefits  under Paragraphs 2, 3 and 4 of this  Part  Two  will
immediately  terminate  in the  event  you  fail  to  abide  by the  restrictive
covenants set forth in Part Three of this letter agreement.  In addition,  those
payments and benefits  will be subject to the dollar  limitation of Part Four of
this letter agreement in the event of your Involuntary  Termination  following a
Change in Control.

                        Part THREE -- CONSULTING SERVICES
                        AND SPECIAL RESTRICTIVE COVENANTS
                        ---------------------------------

1.            Consulting Services.

In  consideration  for the  salary  continuation  payments  to which you  become
entitled  under Part Two,  you will make  yourself  available  during the Salary
Continuation  Period to render such  consulting  services to the Company  within
your area of expertise as may  reasonably  be requested by the  Company's  Chief
Executive Officer, but in no event may more than ten (10) hours of such services
will be required of you per month.

2.            Cessation of Benefits.

Your Salary  Continuation  Period  will  immediately  terminate,  and all salary
continuation  payments and Company-paid  Health Care Coverage and Life Insurance
Coverage will immediately cease, should you:

          (a)  own,  manage,  operate,  join,  control  or  participate  in  the
     ownership,  management,  operation  or  control  of, or be  employed  by or
     connected  in any  manner  with,  any  enterprise  which is  engaged in any
     business  competitive  with or  similar to that of the  Company;  provided,
     however,  that such  restriction  will not apply to any passive  investment
     representing  an interest of less than one percent  (1%) of an  outstanding
     class of publicly-traded securities of any corporation or other enterprise;

          (b) encourage or solicit any of the  Company's  employees to leave the
     Company's  employ  for any reason or  interfere  in any other  manner  with
     employment  relationships  at the time existing between the Company and its
     employees; or

          (c)  induce  any  of  the  Company's  clients,  customers,  suppliers,
     vendors,  distributors,  licensors or licensees to terminate their existing

                                       39
<PAGE>
                                                                               8

     business  relationships  with the Company or  interfere in any other manner
     with any existing business relationship between the Company and any client,
     customer, supplier, vendor, distributor,  licensor, licensee or other third
     party.

                       Part FOUR -- LIMITATION ON BENEFITS
                       -----------------------------------

The benefit  limitation of this Part Four shall be applicable only to the extent
the payments and benefits  made to you pursuant to Paragraphs 2, 3 and 4 of Part
Two are  attributable  to your  Involuntary  Termination  following  a Change in
Control.

1.            Benefit Limit.

The  aggregate  Present  Value  (measured  as of the Change in  Control)  of the
benefits  to  which  you  become  entitled  under  Part  Two at the time of your
Involuntary  Termination,  namely, the salary continuation  payments, the Option
Parachute Payment  attributable to your  Severance-Accelerated  Options and your
Company-paid Health Care Coverage and Life Insurance Coverage,  will in no event
exceed in amount the  greater of the  following  dollar  amounts  (the  "Benefit
Limit"):

          (a) 2.99 times your  Average  Compensation,  less the  Present  Value,
     measured as of the Change in Control,  of all Other  Parachute  Payments to
     which you are entitled, or

          (b) the amount  which  yields  you the  greatest  after-tax  amount of
     benefits under Part Two of this letter  agreement after taking into account
     any excise tax imposed under Code Section 4999 on the payments and benefits
     which are provided you under Part Two or which  constitute  Other Parachute
     Payments.  The Option  Parachute  Payment  attributable  to the accelerated
     vesting of your  Acquisition-Accelerated  Options at the time of the Change
     in Control  shall also be subject to the Benefit  Limitation.  However,  no
     other terms or provisions of your Acquisition-Accelerated  Options shall be
     affected by this letter agreement.

2.       Resolution Procedure.

In the event there is any disagreement between you and the Company as to whether
one or more payments to which you become  entitled in connection with either the
Change  in  Control  or  your  subsequent  Involuntary   Termination  constitute
Parachute Payments,  Option Parachute Payments or Other Parachute Payments or as
to the determination of the Present Value of any of those payments, such dispute
will be resolved as follows:

                                       40
<PAGE>
                                                                               9

          (i) In the event temporary,  proposed or final Treasury Regulations in
     effect  at the  time  under  Code  Section  280G  (or  applicable  judicial
     decisions)  specifically  address  the  status of any such  payment  or the
     method of valuation therefor, the characterization afforded to such payment
     by the Regulations (or such decisions)  will,  together with the applicable
     valuation methodology, be controlling.

          (ii)  In  the  event  Treasury  Regulations  (or  applicable  judicial
     decisions) do not address the status of any payment in dispute,  the matter
     will be  submitted  for  resolution  to  independent  tax counsel  mutually
     acceptable to you and the Company ("Independent  Counsel").  The resolution
     reached by  Independent  Counsel will be final and  controlling;  provided,
     however,  that if  in  the  judgment  of  Independent  Counsel  the  status
     of the  payment in dispute  can be resolved  through  the  obtainment  of a
     private  letter  ruling from the  Internal  Revenue  Service,  a formal and
     proper   request  for  such  ruling  will  be  prepared  and  submitted  by
     Independent  Counsel,  and the  determination  made by the Internal Revenue
     Service in the issued ruling will be controlling.  All expenses incurred in
     connection  with the retention of Independent  Counsel and (if  applicable)
     the preparation and submission of the ruling request will be shared equally
     by you and the Company.

          (iii)  In the  event  Treasury  Regulations  (or  applicable  judicial
     decisions) do not address the  appropriate  valuation  methodology  for any
     payment in dispute,  the Present Value  thereof  will,  at the  Independent
     Counsel's  election,  be  determined  through  an  independent  third-party
     appraisal,  and the expenses  incurred in obtaining  such appraisal will be
     shared equally by you and the Company.

3.            Status of Benefits.

     A. No  benefits  shall  be  provided  you  under  Part  Two of this  letter
agreement  (including the accelerated vesting of your outstanding  Options,  the
salary continuation  payments and the Company-paid Health Care Coverage and Life
Insurance  Coverage)  until the Present  Value of the Option  Parachute  Payment
attributable   to   both   your    Severance-Accelerated    Options   and   your
Acquisition-Accelerated  Options  has  been  determined  and the  status  of any
payments  in dispute  under  Paragraph 2 above has been  resolved in  accordance
therewith.  The post-service exercise period in effect for your Options shall be
stayed and shall not run until the resolution process hereunder is completed.

     B. Once the requisite determinations under Paragraph 2 have been made, then
to the extent the aggregate Present Value, measured as of the Change in Control,

                                       41
<PAGE>
                                                                              10

of (i) the Option Parachute Payment  attributable to your  Severance-Accelerated
Options  plus (ii) the  Parachute  Payment  attributable  to your other  benefit
entitlements  under Part Two of this letter agreement  would,  when added to the
Present  Value  of all your  Other  Parachute  Payments  (including  the  Option
Parachute Payment attributable to your Acquisition-Accelerated  Options), exceed
the Benefit Limit, your salary continuation  payments will first be reduced, and
then the period of your  Company-paid  Health Care  Coverage and Life  Insurance
Coverage will be shortened,  to the extent necessary to assure that such Benefit
Limit is not exceeded.

                           Part Five -- MISCELLANEOUS
                           --------------------------

1.      Termination for Cause.

Should your employment  cease by reason of a Termination for Cause or should you
depart  or  voluntarily  resign  under   circumstances   which  would  otherwise
constitute  grounds for a Termination  for Cause,  then the Company will only be
required to pay you (i) any unpaid  compensation  earned for services previously
rendered  through the date of such  termination  and (ii) any accrued but unpaid
vacation  benefits or sick days,  and no  benefits  will be payable to you under
Part Two of this letter agreement.

2.       Death.

Should you die before  receipt of one or more  salary  continuation  payments to
which you become entitled under this letter agreement,  then those payments will
be made to the executors or administrators of your estate. Should you die before
you exercise all your outstanding  Options as accelerated  hereunder,  then such
Options may be  exercised,  within  twelve (12) months after your death,  by the
executors or administrators of your estate or by persons to whom the Options are
transferred pursuant to your will or in accordance with the laws of inheritance.
In no event,  however,  may any such  Option be  exercised  after the  specified
expiration date of the option term.

3.       General Creditor Status.

All cash payments to which you become entitled hereunder will be paid, when due,
from the general assets of the Company, and no trust fund, escrow arrangement or
other  segregated  account  will be  established  as a funding  vehicle for such
payment.  Accordingly,  your right (or the right of the personal representatives
or beneficiaries of your estate) to receive such cash payments hereunder will at
all times be that of a general creditor of the Company and will have no priority
over the claims of other general creditors.

                                                                              11

4.       Indemnification.

To the maximum  extent  permitted by law,  the  indemnification  provisions  for
Officers  and  Directors   under  the  Company   By-Laws  and   Certificate   of
Incorporation  and  pursuant  to contract  will be  extended to you,  during the
period  following  your  Involuntary  Termination,  with  respect to any and all
matters,  events or  transactions  occurring or effected  during your employment
with the Company.

5.       Miscellaneous.

This letter  agreement  will be binding upon the  Company,  its  successors  and
assigns (including,  without  limitation,  the surviving entity in any Change in
Control) and is to be construed and  interpreted  under the laws of the State of
California.  This letter agreement  supersedes all prior agreements  between you
and the Company  relating to the subject of  severance  benefits  payable upon a
change in control or ownership of the Company or a change in management, and you
will not be entitled to any other  severance  benefits  upon such a  termination
other than those  that are  provided  in this  letter  agreement  and your stock
option  agreements  and the Plan.  This  letter  may only be  amended by written
instrument  signed  by you and an  authorized  officer  of the  Company.  If any
provision  of this letter  agreement  as applied to you or the Company or to any
circumstance should be adjudged by a court of competent  jurisdiction to be void
or unenforceable for any reason, the invalidity of that provision will in no way
affect  (to the  maximum  extent  permissible  by law) the  application  of such
provision under circumstances different from those adjudicated by the court, the
application  of  any  other   provision  of  this  letter   agreement,   or  the
enforceability  or  invalidity of this letter  agreement as a whole.  Should any
provision  of this  letter  agreement  become or be deemed  invalid,  illegal or
unenforceable in any jurisdiction by reason of the scope,  extent or duration of
its coverage, then such provision will be deemed amended to the extent necessary
to  conform  to  applicable  law so as to be valid and  enforceable  or, if such
provision cannot be so amended without materially  altering the intention of the
parties,  then such  provision will be stricken and the remainder of this letter
agreement will continue in full force and effect.

6.        At Will Employment.

Nothing in this  letter  agreement  is intended to provide you with any right to
continue  in the employ of the  Company  (or any  subsidiary)  for any period of
specific duration or interfere with or otherwise restrict in any way your rights
or the  rights of the  Company  (or any  subsidiary),  which  rights  are hereby
expressly reserved by each, to terminate your employment at will or as otherwise
specified in your employment contract.

Please indicate your acceptance of the foregoing by signing the enclosed copy of
this letter and returning it to the Company.

Mr. Dennis P. Wolf

Dear Dennis:

We are pleased to inform you that the Company's  Board of Directors has approved
a  special  severance  benefit  program  for you.  The  purpose  of this  letter
agreement is to set forth the terms and  conditions of your  severance  benefits
and to explain the limitations that will govern their overall value.

Your severance  package will become  payable  should the Company  terminate your
employment,  or should you  otherwise  resign from the  Company,  under  certain
circumstances  following a  substantial  change in  ownership  or control of the
Company or upon the appointment of a new permanent Chief Executive  Officer.  To
understand the full scope of your benefits, you should familiarize yourself with
the definitional  provisions of Part One of this letter agreement.  The benefits
comprising  your  severance  package  are  detailed  in Part  Two,  and  certain
restrictions  applicable to your benefits are specified in Part Three. Part Four
sets forth the dollar  limitation which will govern your total severance package
in the event your  termination  occurs in connection with a change in control or
ownership of the Company.  Part Five deals with ancillary matters affecting your
severance arrangement.

                             Part One -- DEFINITIONS
                             -----------------------

For purposes of this letter  agreement,  the  following  definitions  will be in
effect:

Average  Compensation  means the  average of your W-2 wages from the Company for
the five  (5)  calendar  years  (or  such  fewer  number  of  calendar  years of
employment with the Company) completed immediately prior to the calendar year in
which a Change in  Control  is  effected.  Any W-2  wages for a partial  year of
employment will be annualized, in accordance with the frequency which such wages
are  paid  during  such  partial   year,   before   inclusion  in  your  Average
Compensation.

Base Salary means the monthly rate of base salary in effect for you  immediately
prior to the Change in Control or Change in Management  (as  applicable)  or (if
greater)  the  monthly  rate  of  base  salary  in  effect  at the  time of your
Involuntary Termination.

Board means the Company's Board of Directors.

Change in Control  means a change in the  ownership  or  control of the  Company
effected through any of the following transactions:

                                       45
<PAGE>
                                                                               2

                           (i)  a  merger  or  consolidation   approved  by  the
                  Company's  stockholders  in which  securities  possessing more
                  than fifty percent (50%) of the total combined voting power of
                  the Company's  outstanding  securities  are  transferred  to a
                  person or persons  different  from the persons  holding  those
                  securities immediately prior to such transaction;

                           (ii) any stockholder-approved sale, transfer or other
                  disposition  of all  or  substantially  all  of the  Company's

Option means any option  granted to you under the Plan which is  outstanding  at
the time of the Change in Control or Change in  Management  (as  applicable)  or

Control,  your  Options  will be divided  into two (2)  separate  categories  as
follows:


          Acquisition-Accelerated    Options:   any   outstanding   Option   (or
     installment  thereof)  which  automatically  accelerates,  pursuant  to the
     acceleration  provisions of the agreement  evidencing  that Option,  upon a
     Change in Control.

          Severance-Accelerated  Options: any outstanding Option (or installment
     thereof) which, pursuant to Part Two of this letter agreement,  accelerates
     upon your Involuntary Termination following the Change in Control.

Option  Parachute  Payment  means,  with respect to any  Acquisition-Accelerated
Option or any Severance-Accelerated Option, the portion of that Option deemed to
be a parachute  payment  under Code Section  280G and the  Treasury  Regulations
issued thereunder.  The portion of such Option which is categorized as an Option
Parachute Payment will be calculated in accordance with the valuation provisions
established under Code Section 280G and the applicable Treasury  Regulations and
will  include an  appropriate  dollar  adjustment  to reflect  the lapse of your
obligation  to remain in the  Company's  employ as a condition to the vesting of
the accelerated  installment.  In no event,  however,  will the Option Parachute
Payment    attributable    to    any    Acquisition-Accelerated     Option    or
Severance-Accelerated Option (or accelerated installment) exceed the spread (the
excess of the Fair Market Value of the accelerated option shares over the option
exercise price payable for those shares) existing at the time of acceleration.

Other Parachute  Payment means any payment in the nature of compensation  (other
than the  benefits  to which you become  entitled  under Part Two of this letter
agreement)  which are made to you in  connection  with the Change in Control and
which  accordingly  qualify as  parachute  payments  within the  meaning of Code
Section 280G(b)(2) and the Treasury  Regulations  issued thereunder.  Your Other
Parachute Payment will include (without limitation) the Present Value,  measured
as of  the  Change  in  Control,  of  the  aggregate  Option  Parachute  Payment
attributable to your Acquisition-Accelerated Options (if any).

Parachute  Payment  means any payment or benefit  provided you under Part Two of
this letter  agreement in  connection  with a Change in Control  (other than the
Option Parachute  Payment  attributable to your  Severance-Accelerated  Options)
which is deemed to  constitute  a parachute  payment  within the meaning of Code
Section 280G(b)(2) and the Treasury Regulations issued thereunder.

Plan means (i) the Company's 1993 Stock Option Plan, as amended or restated from
time  to  time,  and  (ii)  any  successor  stock  incentive  plan  subsequently
implemented by the Company.

Present  Value  means  the  value,  determined  as of the date of the  Change in
Control,  of any  payment  in the  nature of  compensation  to which you  become
entitled in connection with the Change in Control or your subsequent Involuntary
Termination,   including  (without  limitation)  the  Option  Parachute  Payment
attributable to your Severance-Acceleration  Options, the additional benefits to
which you become entitled under Part Two of this letter agreement and the Option
Parachute  Payment  attributable to your  Acquisition-Accelerated  Options.  The
Present Value of each such payment will be  determined  in  accordance  with the
provisions  of Code Section  280G(d)(4),  utilizing a discount rate equal to one
hundred twenty  percent  (120%) of the applicable  federal rate in effect at the
time of such  determination,  compounded  semi-annually to the effective date of
the Change in Control or Change. Salary Continuation Period means the period for
which the payment of your Base  Salary may,  pursuant to Part Two of this letter
agreement,  be continued following an Involuntary Termination of your employment
within a specified  period following a Change in Control or Change in Management
(as applicable).

Termination for Cause means the Company's termination of your employment for any
of the following reasons: (i) your commission of any act of fraud,  embezzlement
or dishonesty,  (ii) your  unauthorized use or disclosure of any confidential or
proprietary  information of the Company, (iii) any intentional misconduct by you
which has a materially  adverse effect upon the Company's business or reputation
or (iv) your  continued  failure  to perform  the major  duties,  functions  and
responsibilities  of your position  after you have received  written notice from
the Company identifying the deficiencies in your performance and have been given
a reasonable opportunity to cure those deficiencies, if curable.

                          Part Two - SEVERANCE BENEFITS
                          -----------------------------

Should your  employment  with the Company  terminate by reason of an Involuntary
Termination  within  twelve (12)  months  after a Change in Control or Change in
Management,  then you will become  entitled to receive  the  severance  benefits
provided  under this Part Two.  However,  those  benefits will be subject to the
restrictive covenants of Part Three of this letter agreement and will be in lieu
of all other  severance  benefits to which you might  otherwise be entitled upon
such termination of your employment. In addition, any severance benefits paid to
you in connection with an Involuntary  Termination following a Change in Control
will be subject to the dollar limitation of Part Four.

1.            Accelerated Vesting.

          (a) Change in  Management.  Should  your  employment  with the Company
     terminate by reason of an Involuntary Termination within twelve (12) months
     after a Change in  Management,  then a portion of each  outstanding  Option
     which you hold at the time of your Involuntary  Termination,  to the extent
     not  otherwise  exercisable  for all the shares of Common Stock  subject to


                                       49
<PAGE>
                                                                               6

     that Option,  will immediately  become  exercisable on an accelerated basis
     and  may  be  exercised  for  any or all of  the  shares  subject  to  that
     accelerated  portion until the earlier of (i) the  expiration of the option
     term or (ii) the end of the three  (3)-month  period  following the date of
     your Involuntary Termination.  The number of option shares which shall vest
     and become  exercisable  upon such an accelerated  basis in connection with
     such  Involuntary  Termination  shall be equal to the  number of shares for
     which the Option would have become  exercisable under the Exercise Schedule
     in effect for that Option had you remained in the  Company's  employ for an
     additional  twelve (12) month  period after such  Involuntary  Termination.
     However, to the extent any Option is not exercisable for one or more shares
     at the time of your Involuntary Termination,  after taking into account the
     acceleration  provided under this  paragraph,  the Option will  immediately
     terminate with respect to those shares.

          (b)  Change  in  Control.  Should  your  employment  with the  Company
     terminate by reason of an Involuntary Termination within twelve (12) months
     after a Change in Control,  each  outstanding  Option which you hold at the
     time  of  your  Involuntary  Termination,   to  the  extent  not  otherwise
     exercisable for all the shares of Common Stock subject to that Option, will
     immediately  become  exercisable  for all those  option  shares  and may be
     exercised  for any or all of those shares as fully vested  shares until the
     earlier of (i) the  expiration  of the  option  term or (ii) the end of the
     three (3)-month period following the date of your Involuntary Termination.

2.            Severance Payment.

You will be entitled to salary continuation  payments at your applicable rate of
Base Salary for a Salary Continuation Period of twelve (12) months. These salary
continuation  payments  will be made to you in  accordance  with  the  Company's
normal payroll practices and will be subject to the Company's  collection of all
applicable federal and state income and employment withholding taxes.

3.            Health Care Coverage.

Should you elect continued health care coverage under the Company's medical plan
pursuant to your rights under Code  Section  4980B  ("COBRA"),  the Company will
provide  such  COBRA  coverage,   without  charge,  to  you  and  your  eligible
dependents.  Such  Company-paid  coverage will continue until the earlier of (i)
the  expiration  of your  Salary  Continuation  Period or (ii) the first date on
which you are covered under another  employer's  health benefit  program without
exclusion for any pre-existing  medical  condition.  Any additional  health care
coverage to which you and your  dependents may be entitled under COBRA following
the period of such Company-paid coverage will be at your sole cost and expense.

4.            Life Insurance Coverage.

You  will  be  entitled  to  Life  Insurance  Coverage  through  your  continued
participation  in the Company's  group term and executive life  insurance  plans
following  your  Involuntary  Termination,  and the Company  will pay the entire
premium charged for such continued Life Insurance  Coverage.  Such  Company-paid
coverage  will continue  until the earlier of (i) the  expiration of your Salary
Continuation  Period  or (ii) the  first  date on which  you are  provided  with
comparable coverage under another employer's life insurance plan.  However,  you
will be  responsible  for the  satisfaction  of any  income and  employment  tax
liability  attributable  to your  Company-paid  Life  Insurance  Coverage.  Your
payments  and  benefits  under  Paragraphs  2, 3 and 4 of  this  Part  Two  will
immediately  terminate  in the  event  you  fail  to  abide  by the  restrictive
covenants set forth in Part Three of this letter agreement.  In addition,  those
payments and benefits  will be subject to the dollar  limitation of Part Four of
this letter agreement in the event of your Involuntary  Termination  following a
Change in Control.

                        AND SPECIAL RESTRICTIVE COVENANTS
                        ---------------------------------

1.            Consulting Services.

In  consideration  for the  salary  continuation  payments  to which you  become
entitled  under Part Two,  you will make  yourself  available  during the Salary
Continuation  Period to render such  consulting  services to the Company  within
your area of expertise as may  reasonably  be requested by the  Company's  Chief
Executive Officer, but in no event may more than ten (10) hours of such services
will be required of you per month.

2.            Cessation of Benefits.

Your Salary  Continuation  Period  will  immediately  terminate,  and all salary
continuation  payments and Company-paid  Health Care Coverage and Life Insurance
Coverage will immediately cease, should you:

          (a)  own,  manage,  operate,  join,  control  or  participate  in  the
     ownership,  management,  operation  or  control  of, or be  employed  by or
     connected  in any  manner  with,  any  enterprise  which is  engaged in any
     business  competitive  with or  similar to that of the  Company;  provided,
     however,  that such  restriction  will not apply to any passive  investment
     representing  an interest of less than one percent  (1%) of an  outstanding
     class of publicly-traded securities of any corporation or other enterprise;

          (b) encourage or solicit any of the  Company's  employees to leave the
     Company's  employ  for any reason or  interfere  in any other  manner  with

                                                                               8

     employment  relationships  at the time existing between the Company and its
     employees; or

          (c)  induce  any  of  the  Company's  clients,  customers,  suppliers,
     vendors,  distributors,  licensors or licensees to terminate their existing
     business  relationships  with the Company or  interfere in any other manner
     with any existing business relationship between the Company and any client,
     customer, supplier, vendor, distributor,  licensor, licensee or other third
     party.

                       Part FOUR -- LIMITATION ON BENEFITS
                       -----------------------------------

The benefit  limitation of this Part Four shall be applicable only to the extent
the payments and benefits  made to you pursuant to Paragraphs 2, 3 and 4 of Part
Two are  attributable  to your  Involuntary  Termination  following  a Change in
Control.

1.            Benefit Limit.

The  aggregate  Present  Value  (measured  as of the Change in  Control)  of the
benefits  to  which  you  become  entitled  under  Part  Two at the time of your
Involuntary  Termination,  namely, the salary continuation  payments, the Option
Parachute Payment  attributable to your  Severance-Accelerated  Options and your
Company-paid Health Care Coverage and Life Insurance Coverage,  will in no event
exceed in amount the  greater of the  following  dollar  amounts  (the  "Benefit
Limit"):

          (a) 2.99 times your  Average  Compensation,  less the  Present  Value,
     measured as of the Change in Control,  of all Other  Parachute  Payments to
     which you are entitled, or

          (b) the amount  which  yields  you the  greatest  after-tax  amount of
     benefits under Part Two of this letter  agreement after taking into account
     any excise tax imposed under Code Section 4999 on the payments and benefits
     which are provided you under Part Two or which  constitute  Other Parachute
     Payments.

The Option  Parachute  Payment  attributable to the accelerated  vesting of your
Acquisition-Accelerated  Options at the time of the Change in Control shall also
be subject to the Benefit  Limitation.  However, no other terms or provisions of
your Acquisition-Accelerated Options shall be affected by this letter agreement.

2.            Resolution Procedure.

In the event there is any disagreement between you and the Company as to whether
one or more payments to which you become  entitled in connection with either the
Change  in  Control  or  your  subsequent  Involuntary   Termination  constitute
Parachute Payments,  Option Parachute Payments or Other Parachute Payments or as

                                       52
<PAGE>
                                                                               9

to the determination of the Present Value of any of those payments, such dispute
will be resolved as follows:

          (i) In the event temporary,  proposed or final Treasury Regulations in
     effect  at the  time  under  Code  Section  280G  (or  applicable  judicial
     decisions)  specifically  address  the  status of any such  payment  or the
     method of valuation therefor, the characterization afforded to such payment
     by the Regulations (or such decisions)  will,  together with the applicable
     valuation methodology, be controlling.

          (ii)  In  the  event  Treasury  Regulations  (or  applicable  judicial
     decisions) do not address the status of any payment in dispute,  the matter
     will be  submitted  for  resolution  to  independent  tax counsel  mutually
     acceptable to you and the Company ("Independent  Counsel").  The resolution
     reached by  Independent  Counsel will be final and  controlling;  provided,
     however,  that  if  in  the  judgment  of  Independent  Counsel  the status
     of the  payment in dispute  can be resolved  through  the  obtainment  of a
     private  letter  ruling from the  Internal  Revenue  Service,  a formal and
     proper   request  for  such  ruling  will  be  prepared  and  submitted  by
     Independent  Counsel,  and the  determination  made by the Internal Revenue
     Service in the issued ruling will be controlling.  All expenses incurred in
     connection  with the retention of Independent  Counsel and (if  applicable)
     the preparation and submission of the ruling request will be shared equally
     by you and the Company.

          (iii)     In the event Treasury  Regulations (or  applicable  judicial
     decisions) do not address the  appropriate  valuation  methodology  for any
     payment in dispute,  the Present Value  thereof  will,  at the  Independent
     Counsel's  election,  be  determined  through  an  independent  third-party
     appraisal,  and the expenses  incurred in obtaining  such appraisal will be
     shared equally by you and the Company.

3.            Status of Benefits.

          A. No  benefits  shall be  provided  you under Part Two of this letter
     agreement  (including the accelerated vesting of your outstanding  Options,
     the salary continuation  payments and the Company-paid Health Care Coverage
     and  Life  Insurance  Coverage)  until  the  Present  Value  of the  Option
     Parachute Payment attributable to both your  Severance-Accelerated  Options
     and your Acquisition-Accelerated Options has been determined and the status
     of any  payments in dispute  under  Paragraph 2 above has been  resolved in
     accordance  therewith.  The post-service exercise period in effect for your
     Options  shall be stayed  and shall  not run until the  resolution  process
     hereunder is completed.

                                       53

                                                                              10

          B. Once the requisite determinations under Paragraph 2 have been made,
     then to the extent the aggregate  Present Value,  measured as of the Change
     in  Control,  of (i) the  Option  Parachute  Payment  attributable  to your
     Severance-Accelerated  Options  (or  installments  thereof)  plus  (ii) the
     Parachute  Payment  attributable to your other benefit  entitlements  under
     Part Two of this letter agreement would, when added to the Present Value of
     all your Other Parachute  Payments  (including the Option Parachute Payment
     attributable to your  Acquisition-Accelerated  Options), exceed the Benefit
     Limit, your salary  continuation  payments will first be reduced,  and then
     the period of your  Company-paid  Health Care  Coverage and Life  Insurance
     Coverage  will be  shortened,  to the extent  necessary to assure that such
     Benefit Limit is not exceeded.

                            Part Five - MISCELLANEOUS
                            -------------------------

1.            Termination for Cause.

Should your employment  cease by reason of a Termination for Cause or should you
depart  or  voluntarily  resign  under   circumstances   which  would  otherwise
constitute  grounds for a Termination  for Cause,  then the Company will only be
required to pay you (i) any unpaid  compensation  earned for services previously
rendered  through the date of such  termination  and (ii) any accrued but unpaid
vacation  benefits or sick days,  and no  benefits  will be payable to you under
Part Two of this letter agreement.

2.            Death.

Should you die before  receipt of one or more  salary  continuation  payments to
which you become entitled under this letter agreement,  then those payments will
be made to the executors or administrators of your estate. Should you die before
you exercise all your outstanding  Options as accelerated  hereunder,  then such
Options may be  exercised,  within  twelve (12) months after your death,  by the
executors or administrators of your estate or by persons to whom the Options are
transferred pursuant to your will or in accordance with the laws of inheritance.
In no event,  however,  may any such  Option be  exercised  after the  specified
expiration date of the option term.

3.            General Creditor Status.

All cash payments to which you become entitled hereunder will be paid, when due,
from the general assets of the Company, and no trust fund, escrow arrangement or
other  segregated  account  will be  established  as a funding  vehicle for such
payment.  Accordingly,  your right (or the right of the personal representatives
or beneficiaries of your estate) to receive such cash payments hereunder will at
all times be that of a general creditor of the Company and will have no priority
over the claims of other general creditors.

4.            Indemnification.

To  the  maximum  extent  permitted  by  applicable  law,  the   indemnification
provisions for Officers and Directors  under the Company By-Laws and Certificate
of  Incorporation  and pursuant to contract will be extended to you,  during the
period  following  your  Involuntary  Termination,  with  respect to any and all
matters,  events or  transactions  occurring or effected  during your employment
with the Company.

5.            Miscellaneous.

This letter  agreement  will be binding upon the  Company,  its  successors  and
assigns (including,  without  limitation,  the surviving entity in any Change in
Control) and is to be construed and  interpreted  under the laws of the State of
California.  This letter agreement  supersedes all prior agreements  between you
and the Company  relating to the subject of  severance  benefits  payable upon a
change in control or ownership of the Company or a change in management, and you
will not be entitled to any other  severance  benefits  upon such a  termination
other than those that are provided in this letter agreement or your stock option
agreements and the Plan. This letter  agreement  specifically  supersedes  those
provisions of the employee  offer letter  agreement  dated March 13, 1998 by and
between the Company and you as such  provisions  relate to the subject matter of
this letter  agreement.  This  letter may only be amended by written  instrument
signed by you and an authorized officer of the Company. If any provision of this
letter agreement as applied to you or the Company or to any circumstance  should
be adjudged by a court of competent jurisdiction to be void or unenforceable for
any  reason,  the  invalidity  of that  provision  will in no way affect (to the
maximum  extent  permissible by law) the  application  of such  provision  under
circumstances  different from those adjudicated by the court, the application of
any  other  provision  of  this  letter  agreement,  or  the  enforceability  or
invalidity  of this letter  agreement as a whole.  Should any  provision of this
letter  agreement  become or be deemed invalid,  illegal or unenforceable in any
jurisdiction  by reason of the scope,  extent or duration of its coverage,  then
such  provision  will be deemed  amended to the extent  necessary  to conform to
applicable law so as to be valid and enforceable or, if such provision cannot be
so amended without materially  altering the intention of the parties,  then such
provision  will be stricken  and the  remainder  of this letter  agreement  will
continue in full force and effect.

6.            At Will Employment.

Nothing in this  letter  agreement  is intended to provide you with any right to
continue  in the employ of the  Company  (or any  subsidiary)  for any period of
specific duration or interfere with or otherwise restrict in any way your rights
or the  rights of the  Company  (or any  subsidiary),  which  rights  are hereby
expressly reserved by each, to terminate your employment at will or as otherwise
specified in your employment contract.

Dr. William G. Howard, Jr.

Dear Bill:

                  This letter agreement is intended to memorialize the terms and
conditions under which you have agreed to serve as the Chairman of the Company's
Board of Directors and for your services performed during the period the Company
is  engaged in the search for a new Chief  Executive  Officer.  Those  terms and
conditions may be summarized as follows:

1.   You will  assume your new  position as Chairman of the Board of  Directors,
     effective  December  8,  1998,  and  during  the  period  you serve in that
     capacity  prior  to  the  Board's  appointment  of a  new  permanent  Chief
     Executive Officer, you will have both executive officer and employee status
     with the Company.

2.   As an employee, your base salary will be $10,000 per month and will be paid
     in accordance with the Company's normal payroll  practices,  subject to the
     Company's   collection  of  all   applicable   income  and  employment  tax
     withholdings.  You will be reimbursed for all reasonable  expenses incurred
     in connection with your employment.

3.   You were  granted a stock  option on December  8, 1998 to  purchase  15,000
     shares of the Company's  common stock at an exercise  price of $19.8125 per
     share,  the closing selling price on December 8, 1998. The option will be a
     non-statutory  option  under the  federal  tax laws and will have a maximum
     term of ten (10) years,  subject to earlier termination upon your cessation
     of service with the Company as an employee, consultant or Board member. The
     option  will  become  exercisable  for all of the  option  shares  upon the
     earlier of (i) your completion of six (6) years of service with the Company
     measured  from  the  December  8,  1998  grant  date  or (ii)  the  Board's
     appointment of a new permanent Chief Executive Officer.

4.   During your period of employment with the Company, you will not be eligible
     to receive  any  compensation  payable to the  non-employee  members of the
     Board,  whether in the form of cash fees or automatic  option  grants under
     the Company's 1993 Stock Option Plan.

5.   You will be eligible to participate in all group term life insurance plans,
     group health plans, accidental death and dismemberment plans and short-term
     disability  programs  and  other  executive   perquisites  which  are  made
     available to the Company's  executives and for which you qualify.  You will
     accrue  paid  vacation  benefits  at the rate of one (1) week per  calendar
     quarter.

6.   The executive  officer and employee  status of your position as Chairman of
     the Board is not for any specified period of time. As a result,  either you
     or the  Company  are  free to  terminate  that  status  at any time for any
     reason, with or without cause. In addition, your employment status with the
     Company will terminate  immediately  upon the Board's  appointment of a new
     Chief Executive Officer or upon your death or disability.  At the time your
     employment status terminates,  the Company will only be required to pay you
     (i) any unpaid base salary for services  rendered  through the date of such
     termination  and (ii) the dollar  value of all accrued and unused  vacation
     benefits  based upon the level of base salary in effect for you at the time
     of your termination. The termination of your executive officer and employee
     status will not affect  your  continuation  on the Board as a  non-employee
     director or as Chairman of the Board, if the Board so determines.

7.   This letter agreement  constitutes the full and complete  agreement between
     us  concerning  the  terms of your  service  as an  executive  officer  and
     employee of the Company in your capacity as Chairman of the Board. Although
     your duties, title,  compensation and/or benefits, as well as the Company's
     personnel  policies and  procedures,  may change from time to time, the "at
     will" nature of your  employment may only be changed by an express  written
     agreement signed by you and a duly authorized officer of the Company.

         To indicate your acceptance of the foregoing terms of your  employment,
please sign the acceptance paragraph below and return it to my attention.

                                Very truly yours,

                                /s/ Dennis Wolf_____________________
