                            NANOMETRICS INCORPORATED
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1.       Condensed Consolidated Financial Statements

       The condensed  consolidated  financial statements include the accounts of
Nanometrics  Incorporated  and its  wholly-owned  subsidiaries.  All significant
inter-company accounts and transactions have been eliminated.

       While the quarterly  condensed  financial  statements are unaudited,  the
financial statements included in this report reflect all adjustments (consisting
only of normal recurring  adjustments) which Nanometrics considers necessary for
a fair presentation of the results of operations for the interim periods covered
and of our financial  condition at the date of the interim balance  sheets.  The
operating  results for interim  periods are not  necessarily  indicative  of the
operating  results  that may be expected for the entire  year.  The  information
included  in this  report  should be read in  conjunction  with the  information
included  in  Nanometrics'  2002  Annual  Report  on Form  10-K  filed  with the
Securities and Exchange Commission.


Note 2.       Significant Accounting Policies

         Income  Taxes - Deferred  income  taxes  reflect the net tax effects of
temporary differences between the carrying amounts of assets and liabilities for
financial  reporting  purposes  and the amounts used for income tax purposes and
operating  loss and tax credit  carryforwards  measured  by  applying  currently
enacted tax laws.  A valuation  allowance is provided  when  necessary to reduce
deferred  tax assets to an amount that is more  likely than not to be  realized.
During the  quarter  ended  March 31,  2003,  Nanometrics  recorded a  valuation
allowance of $6,020,000 and will continue to provide a full valuation  allowance
against deferred tax assets for the foreseeable future.

         Short-Term  Investments  -  Short-term  investments  consist  of United
States  Treasury  bills and are  stated  at fair  value  based on quoted  market
prices.  Short-term  investments are classified as  available-for-sale  based on
Nanometrics'  intended use. The difference between amortized cost and fair value
representing  unrealized  holding gains or losses are recorded as a component of
shareholders'  equity  as  accumulated  other  comprehensive  loss  and  was not
significant  as of June 30,  2003.  Gains  and  losses  on  sales of  short-term
investments are determined on a specific identification basis.

Note 3.       Inventories

Note 8.       Stock-Based Compensation

      Nanometrics  accounts for  stock-based  compensation  using the  intrinsic
value method in accordance  with the provision of  Accounting  Principles  Board
Opinion  No.  25,  Accounting  for Stock  Issued to  Employees,  as  allowed  by
Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock
Based  Compensation  as  amended by SFAS No.  148,  Accounting  for Stock  Based
Compensation-Transition and Disclosures, an Amendment of FASB Statement No. 123.

      Under the  intrinsic  value  method,  Nanometrics  does not  recognize any
compensation expense, as the exercise price of all stock options is equal to the
fair market value at the time the options are granted.  Had compensation expense
been  recognized  using  the  fair  value-based  methods  under  SFAS  No.  123,
Nanometrics' pro forma  consolidated  loss and loss per share would have been as
follows (in thousands, except per share amounts):

employees  are  allowed to have salary  withholdings  of up to 10% of their base
compensation  to purchase  shares of common stock at a price equal to 85% of the
lower of the market value of the stock at the beginning or end of each six-month
offering period, subject to an annual limitation. The first offering period will
begin October 2003.

ITEM  2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

       This report, including the following Management's Discussion and Analysis
of  Financial  Condition  and Results of  Operations,  contains  forward-looking
statements  within the meaning of Section 27A of the Securities Act of 1933, and
Section  21E of  the  Securities  Exchange  Act of  1934.  Such  forward-looking
statements  are based upon current  expectations  and beliefs that involve risks
and  uncertainties,  such as our plans,  objectives and  intentions,  regarding,
among other things: (i) customer demand for our products,  which may be affected
by several  factors  including the  cyclicality of the  semiconductor,  magnetic
recording head, flat panel display and other industries that we serve,  patterns
of capital  spending by our customers,  technological  changes in the markets we
serve, and market acceptance of our products and our customers'  products;  (ii)
the timing,  cancellation or delay of our customers' orders and shipments; (iii)
competition,  including  competitive  pressures on product prices and changes in
pricing by our customers or suppliers;  (iv)  fluctuations  in foreign  currency
exchange  rates,  particularly  the Japanese yen; (v) the proportion of sales we
make  directly  to  our  customers   versus  sales  through   distributors   and
representatives;  (vi) market  acceptance  of new and  enhanced  versions of our
products;  (vii)  the  timing of our new  product  announcements  and  releases,
including  our ability to design,  introduce and  manufacture  new products in a
timely and cost effective  manner,  as well as the announcements and releases by
our  competitors;  and (viii) the size and timing of acquisitions of businesses,
products  or  technologies  and  fluctuations  in the  availability  and cost of
components and subassemblies of our products.

       In some cases, forward-looking statements can be identified by words such
as "believe," "expect," "anticipate," "plan," "potential," "continue" or similar
expressions.  Forward-looking statements also include the assumptions underlying
or relating to any of the foregoing statements.  Our actual results could differ
materially  from those  anticipated  in these  forward-looking  statements  as a
result of  certain  risk  factors,  including  those set forth in  "Management's
Discussion  and  Analysis of  Financial  Condition  and Results of  Operations -
Factors That May Affect Future  Operating  Results" in Nanometrics'  2002 Annual
Report  on Form  10-K.  We  believe  that it is  important  to  communicate  our
expectations to our investors.  However,  there may be events in the future that
we are not able to  predict  accurately  or over which we have no  control.  You
should be aware that the occurrence of the events described in such risk factors
and elsewhere in this report could materially and adversely affect our business,
operating results and financial condition.

       All  forward-looking  statements  included  in this  report  are based on
information  available to us on the date hereof.  We undertake no  obligation to
update  forward-looking  statements  made in this  report to  reflect  events or
circumstances  after the date of this  report or to update  reasons  why  actual
results could differ from those anticipated in such forward-looking statements.

Overview

       We are a leader in the design, manufacture, marketing and support of thin
film metrology  systems for the  semiconductor,  flat panel display and magnetic
recording head industries.  Our systems  precisely  measure a wide range of film
types  deposited  on  substrates  during   manufacturing  in  order  to  control
manufacturing processes and increase production yields.

Critical Accounting Policies

       Income Tax Assets and  Liabilities - We account for income taxes based on
Statement of Financial Accounting Standards (SFAS) No. 109 Accounting for Income
Taxes,  whereby  deferred tax assets and  liabilities  must be recognized  using
enacted tax rates for the effect of temporary  differences  between the book and
tax accounting  for assets and  liabilities.  Also,  deferred tax assets must be
reduced by a valuation allowance if it is more likely than not that a portion of
the  deferred  tax assets will not be realized  in the future.  We evaluate  the
deferred tax assets on a quarterly basis to determine whether or not a valuation
allowance is  appropriate.  Factors used in this  determination  include  future
expected  income and the  underlying  asset or  liability  which  generated  the
temporary tax difference.


                                       10


       Our income tax  provision is based on estimates of our  effective  income
tax rate for the year.  The effective tax rate is generally  estimated  based on
the geographic  distribution of profits,  the tax rates in different regions and
the availability of tax credits. If actual results differ from our estimates, it
may be  necessary  to record a valuation  allowance on deferred tax assets or to
adjust  our  effective  tax rate,  which  could  have a  material  effect on our
financial results.

Results of Operations

       Total  net  revenues  for the  three  months  ended  June 30,  2003  were
$9,734,000, an increase of $1,342,000 or 16% from the comparable period in 2002.
For the six months  ended  June 30,  2003,  total net  revenues  of  $19,084,000
increased $2,667,000 or 16% from the comparable period in 2002. Product sales of
$7,865,000  and  $15,300,000  for the three months and six months ended June 30,
2003,   respectively,   increased   $729,000  or  10%  and   $1,303,000  or  9%,
respectively,  as compared with the same periods during 2002. Sales of automated
and tabletop  systems  increased in the second quarter of 2003 from their second
quarter 2002  levels.  The increase in product  sales  resulted  from demand for
semiconductor  process  control  equipment  and flat  panel  display  equipment,
primarily in the Far East.  Service revenue of $1,869,000 and $3,784,000 for the
three  months  and six  months  ended  June 30,  2003,  respectively,  increased
$613,000 or 49% and  $1,364,000  or 56%,  respectively,  as compared to the same
periods  in  2002   primarily  due  to  higher  sales  of  parts  and  services,
particularly  in the U.S.  and the Far East,  due in part to a larger  installed
base of systems that have passed their warranty periods.

       Cost of product sales as a percentage  of product sales  increased to 61%
in the  second  quarter  of 2003  from  42% in the  second  quarter  of 2002 and
increased  to 55% in the six months  ended  June 30,  2003 from 42% for the same
period  in 2002 due in part to lower  sales  prices  on  older  products  and an
increase in  manufacturing  capacity added to our U.S.  facility.  The increased
manufacturing capacity is part of a strategic move to internalize the production
of key parts and  components,  allowing us to have  greater  control  over their
development,  delivery,  quality and cost.  Cost of service as a  percentage  of
service revenue  decreased to 86% in the second quarter of 2003 from 116% in the
second  quarter of 2002 and  decreased  to 92% in the six months  ended June 30,
2003 from 112% for the same period in 2002 due to higher service revenues, which
exceeded our cost of service.

       Research  and  development  expenses  for the  three  month and six month
periods  ended June 30, 2003  increased  by $416,000 or 14% and  $403,000 or 6%,
respectively,  compared to the same  periods in 2002  resulting  primarily  from
increased headcount and related expenses for the development of new and enhanced
products.

       Selling  expenses for the three months and six month  periods  ended June
30, 2003 increased by $16,000 or 1% and $680,000 or 14%, respectively,  compared
to the same periods in 2002  primarily due to higher  headcount  levels,  higher
commissions and other expenses incurred  promoting our products  particularly in
the first quarter of 2003.

       General and  administrative  expenses for the three months ended June 30,
2003  decreased  $97,000 or 8% from the same period in 2002 due in part to lower
salary and  consulting  expenses  resulting  from shutdown days taken during the
quarter.  General and administrative  expenses for the six months ended June 30,
2003 increased  $171,000 or 8% compared to the same period in 2002 due primarily
to higher  regulatory  compliance and patent related costs  particularly  in the
first quarter of 2003.

       Total other  income,  net for the three month and six month periods ended
June 30, 2003 decreased $310,000 or 95% and $288,000 or 76%, respectively,  from
the comparable periods in 2002 due primarily to lower interest income, resulting
from lower  investment  balances and lower interest  rates and foreign  currency
transaction loss.

       A provision for income taxes of $6,088,000 was recorded for the six-month
period  ended June 30,  2003,  which  primarily  represents a charge to record a
valuation  allowance  against deferred income tax assets.  This charge was taken
primarily as a result of pretax losses  incurred over the past several  quarters
coupled with  uncertainty  about future  expected  income in the current  market
environment, making it more likely than not that the deferred tax asset will not
be realized.

       As a result of the factors  discussed above, our loss from operations was
$4,033,000  and net loss was  $4,083,000 for the second quarter of 2003 compared
to a loss from  operations  of $3,088,000  and a net loss of $1,702,000  for the
same period in 2002. For the first six months of 2003, our loss from  operations
was  $7,670,000  and net loss was


                                       11


$13,667,000  which  compared to a loss from  operations of $5,635,000  and a net
loss of $3,249,000 for the same period in 2002.

Liquidity and Capital Resources

         At June 30, 2003, our cash, cash equivalents and short-term investments
totaled $30,657,000.  Our short-term  investments are invested primarily in U.S.
Treasury Bills. At June 30, 2003, Nanometrics had working capital of $61,672,000
compared to $74,776,000 at December 31, 2002. The current ratio at June 30, 2002
was 14.2 to 1. We believe that working capital  including cash, cash equivalents
and short-term investments will be sufficient to meet our needs through at least
the next twelve months.

         Operating  activities  for the  first  six  months of 2003 used cash of
$5,551,000  primarily from the net loss, lower accounts  payable  resulting from
lower levels of materials  purchases and lower deferred  revenue.  These uses of
cash were offset to some extent by lower  inventory  levels as we  continued  to
limit our  purchases of inventory  during the quarter in an effort to reduce our
use of cash.  Investing activities provided $2,462,000 primarily due to sales of
short-term  investments  of  $29,000,000  offset to some extent by  purchases of
short-term  investments in the amount of $26,012,000 and capital expenditures of
$526,000 used to continue to internalize our manufacturing  capacity in the U.S.
Financing   activities  used  $123,000   primarily  due  to  repayment  of  debt
obligations in Japan.

         We have  evaluated  and will  continue to evaluate the  acquisition  of
products,  technologies  or businesses that are  complementary  to our business.
These  activities  may result in product  and  business  investments,  which may
affect our cash position and working capital balances.


ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

       We are  exposed to  financial  market  risks,  which  include  changes in
foreign  currency  exchange rates and interest  rates.  We do not use derivative
financial  instruments.  Instead,  we  actively  manage the  balances of current
assets and liabilities  denominated in foreign  currencies to minimize  currency
fluctuation risk. As a result, a hypothetical 10% change in the foreign currency
exchange rates at June 30, 2003 would not have a material  impact on our results
of operations.  Our investments in marketable securities are subject to interest
rate risk but, due to the short-term nature of these investments,  interest rate
changes  would not have a material  impact on their value at June 30,  2003.  We
also have  fixed rate yen  denominated  debt  obligations  in Japan that have no
interest rate risk. At June 30, 2003,  our total debt  obligation was $3,723,000
with a long-term  portion of $2,747,000.  A hypothetical  10% change in interest
rates at June 30,  2003  would  not have a  material  impact on our  results  of
operations.

ITEM 4.  CONTROLS AND PROCEDURES

       We maintain  disclosure  controls  and  procedures  that are  designed to
ensure that  information  required to be disclosed in the periodic reports filed
by us  with  the  Securities  and  Exchange  Commission  (the  "Commission")  is
recorded,  processed,  summarized and reported within the time periods specified
in  the  rules  and  forms  of the  Commission  and  that  such  information  is
accumulated and communicated to our management.  In designing and evaluating the
disclosure controls and procedures,  our management recognized that any controls
and  procedures,  no matter how well  designed  and  operated,  can provide only
reasonable  assurance of achieving the desired control objectives and management
necessarily  was required to apply its judgment in evaluating  the  cost-benefit
relationship of possible controls and procedures.

       Based on their most recent evaluation, which was completed within 90 days
prior to the  filing  date of this  quarterly  report  on Form  10-Q,  our Chief
Executive Officer and Chief Financial Officer have concluded that our disclosure
controls and procedures  (as defined in Rule 13a-14 of the  Securities  Exchange
Act of 1934, as amended) are effective.  There were not any significant  changes
in internal controls or in other factors that could  significantly  affect these
internal controls subsequent to the date of their most recent evaluation.

I, John D. Heaton, certify that:

      1.    I have reviewed this  quarterly  report on Form 10-Q of  Nanometrics
            Incorporated;

      2.    Based on my knowledge,  this  quarterly  report does not contain any
            untrue statement of a material fact or omit to state a material fact
            necessary to make the statements made, in light of the circumstances
            under which such  statements  were made, not misleading with respect
            to the period covered by this quarterly report;

      3.    Based on my knowledge, the financial statements, and other financial
            information included in this quarterly report, fairly present in all
            material respects the financial condition, results of operations and
            cash flows of the  registrant as of, and for, the periods  presented
            in this quarterly report;

      4.    The registrant's other certifying officers and I are responsible for
            establishing and maintaining  disclosure controls and procedures (as
            defined in Exchange Act Rules 13a-14 and 15d-14) for the  registrant
            and have:

            (a)   designed  such  disclosure  controls and  procedures to ensure
                  that  material   information   relating  to  the   registrant,
                  including its consolidated  subsidiaries,  is made known to us
                  by others  within  those  entities,  particularly  during  the
                  period in which this quarterly report is being prepared;

            (b)   evaluated the  effectiveness  of the  registrant's  disclosure
                  controls and  procedures  as of a date within 90 days prior to
                  the filing  date of this  quarterly  report  (the  "Evaluation
                  Date"); and

            (c)   presented in this quarterly  report our conclusions  about the
                  effectiveness of the disclosure  controls and procedures based
                  on our evaluation as of the Evaluation Date;

      5.    The  registrant's  other  certifying  officer and I have  disclosed,
            based on our most recent  evaluation,  to the registrant's  auditors
            and the audit  committee  of  registrant's  board of  directors  (or
            persons performing the equivalent function):

            (a)   all  significant  deficiencies  in the design or  operation of
                  internal   controls   which   could   adversely   affect   the
                  registrant's ability to record, process,  summarize and report
                  financial  data  and  have  identified  for  the  registrant's
                  auditors any material weaknesses in internal controls; and

            (b)   any fraud,  whether or not material,  that involves management
                  or  other  employees  who  have  a  significant  role  in  the
                  registrant 's internal controls; and

      6.    The registrant's  other  certifying  officer and I have indicated in
            this quarterly report whether or not there were significant  changes
            in internal  controls or in other  factors that could  significantly
            affect internal  controls  subsequent to the date of our most recent
            evaluation,   including  any  corrective   actions  with  regard  to
            significant deficiencies and material weaknesses.
