                            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
intercompany accounts and transactions have been eliminated.


         While the quarterly  condensed  consolidated  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 its  financial  condition  at the  date of the
interim  balance  sheet.  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' 2003 Annual Report on
Form 10-K filed with the Securities and Exchange Commission.


Note 2.  Significant Accounting Policies


         Fiscal Period - Nanometrics uses a 52/53 week fiscal year ending on the
Saturday  nearest to December  31. In prior  financial  statements,  Nanometrics
presented for convenience all periods as if they ended on the month end date. To
provide greater clarity, these financial statements include references to actual
period end dates.  All  references to the quarter refer to  Nanometrics'  fiscal
quarter. The fiscal quarters presented herein include 13 weeks.

         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 29,  2003,  Nanometrics  recorded a  valuation
allowance of  $6,020,000.  The valuation  allowance was recorded  primarily as a
result of pre tax losses  incurred over the past several  quarters  coupled with
uncertainty  about future  expected  income in the current  market  environment,
making it not more likely than not that the deferred tax asset will be realized.

         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 April 3, 2004 and January 3, 2004.  Gains and losses on sales
of short-term investments are determined on a specific identification basis.

in the basic and  diluted net income per share  computations  are as follows (in
thousands):

Note 8.  Stock-Based Compensation - As restated

         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   method  under  SFAS  No.  123,
Nanometrics' pro forma  consolidated  loss and loss per share would have been as
follows (in thousands, except per share amounts):




                                                                             Three Months Ended

Basic and diluted net loss per share:

         Subsequent  to the  issuance of its  condensed  consolidated  financial
statements  for  the  quarter  ended  April  3,  2004,  Nanometrics'  management
determined  that the pro forma total and per share net loss had been  improperly
calculated for the three months ended April 3, 2004. As a result,  the pro forma
total and per share net loss for the three  months ended April 3, 2004 have been

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
and flat panel display  industries served by us, patterns of capital spending by
its  customers,  technological  changes  in the  markets  served  by us and  our
customers, and market acceptance of our products and of our customers' products;
(ii) the timing,  cancellation  or delay of our customer  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 new product announcements and releases of products
by us or our  competitors,  including  our  ability  to  design,  introduce  and
manufacture new products on a timely and cost effective  basis;  (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'
2003 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, financial condition and cash flows.


         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
high-performance  process control  metrology  systems used in the manufacture of
semiconductors  and flat panel displays.  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  asset  will  not  be  realized in the future. We evaluate the


                                       10


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.

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.

Results of Operations

         Total net revenues for the first quarter of 2004 were  $13,671,000,  an
increase of  $4,321,000  or 46% from the same quarter in 2003.  Product sales of
$11,663,000 for the first quarter of 2004,  increased $4,228,000 or 57% compared
to the same period in 2003. Sales of integrated  systems  increased in the first
quarter of 2004 from their first  quarter 2003  levels.  The increase in product
sales resulted from stronger demand for semiconductor  process control metrology
equipment,  particularly in the U.S. and the Far East. This increased  demand is
driven  in  part  by the  semiconductor  industry's  continued  shift  from  the
manufacture of 200 millimeter  wafers to 300 millimeter  wafers,  which requires
new products that can handle the larger  wafers.  Service  revenue of $2,008,000
increased $93,000 or 5% in the first quarter of 2004 compared to the same period
in 2003  primarily due to higher sales of parts and services in the U.S. and the
Far East  resulting  in part from a larger  installed  base of systems that have
passed their warranty periods.

         Cost of product sales as a percentage of product sales decreased to 46%
in the first quarter of 2004 from 49% in the first quarter of 2003 due primarily
to  increased  product  sales volume  resulting in lower per unit  manufacturing
costs.  Cost of service as a percentage of service  revenue  decreased to 80% in
the first quarter of 2004 from 98% in the first  quarter of 2003  primarily as a
result of the mix of services  provided  to  customers  which  resulted in lower
materials costs in the first quarter of 2004.

         Research  and  development  expenses  for  the  first  quarter  of 2004
increased  $116,000 or 3% compared  to the same  period in 2003  primarily  as a
result of higher materials expenses as we continued to invest in the development
of new and enhanced products.

         Selling expenses for the first quarter of 2004 increased by $180,000 or
6% compared to the same period in 2003  primarily due to higher travel  expenses
and other  expenses  incurred  promoting  our products to existing and potential
customers.

         General  and  administrative  expenses  for the first  quarter  of 2004
increased  by $112,000 or 9% compared to the same period in 2003  primarily as a
result of increased  headcount,  higher  insurance costs and higher  information
technology costs.

         Total  other  income,  net  decreased  $49,000  or 67% during the first
quarter  of 2004  compared  to the same  period in 2003 due  primarily  to lower
interest  income  as a  result  of  lower  interest  rates  and  lower  cash and
short-term investments balances.

         A provision  for income taxes of  $6,020,000  was recorded in the first
quarter  of 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 not more likely than not that the deferred tax asset will be realized.

         As a result of the factors  discussed  above,  our loss from operations
was $1,193,000 and our net loss was $1,212,000 or $0.10 per diluted share in the
first quarter of 2004 compared to a loss from operations of $3,637,000 and a net
loss of $9,584,000 or $0.80 per diluted share in the first quarter of 2003.


                                       11

Liquidity and Capital Resources


         At April 3, 2004, our cash and cash equivalents totaled $24,075,000. At
April 3, 2004, we had working capital of $59,117,000  compared to $59,587,000 at
January 3,  2004.  The  current  ratio at April 3, 2004 was 5.9 to 1. We believe
that our working  capital,  including  cash,  cash  equivalents  and  short-term
investments  will be  sufficient  to meet our  needs at least  through  the next
twelve months.


         Operating  activities  for the first three  months of 2004 used cash of
$6,191,000  primarily from the net loss and higher  accounts  receivable,  which
resulted from  increased  sales and the timing of shipments  and  receipts,  and
increased  inventory  needed to support our higher sales.  Investing  activities
provided  $21,499,000  primarily  due to  sales  of  short-term  investments  of
$21,943,000  offset to some extent by capital  expenditures  of $444,000 used to
continue the process of internalizing our  manufacturing  capacity in the United
States.  Financing  activities  provided  $899,000  primarily  due to short term
borrowing of $910,000 in Japan,  which was offset to some extent by repayment of
long-term  debt in Japan,  and by stock  issuances  from the  exercise  of stock
options by employees.

         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 April 3,  2004  would not have had a  material  impact on our
results  of  operations.  At April 3,  2004,  our total  debt  obligations  were
$4,415,000 with a long-term portion of $2,490,000.  A hypothetical 10% change in
interest  rates at April 3,  2004  would not have had 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,  our Chief Executive Officer and
Chief  Financial  Officer  have  concluded  that  our  disclosure  controls  and
procedures (as defined in Rules 13a-14 and 15d-14 of the Securities Exchange Act
of 1934, as amended) are  effective as of the end of the period  covered by this
Quarterly  Report  on Form  10-Q.  There  were not any  significant  changes  in
internal  controls  or in other  factors  that  could  significantly  affect our
internal controls during our last fiscal quarter.
