John Heaton - Nanometrics - President, CEO

Hello and welcome to our Q4 2004 and 2004 year-end conference call.

                                      * * *

Please note that since our company is currently  engaging in a transaction  with
August Technology Incorporated and the transcript of our conference call must be
filed  with the SEC,  this  will  result in a slight  delay for those  investors
wishing to listen to a replay of the conference call.

In today's call, I'd like to take the opportunity to review the quarter and then
highlight  some of our  achievements  for  2004,  followed  by an  update on our
pending  transaction  with August  Technology.  After  that,  we will open up to
questions.

                                      * * *

As we prepare for our potential  merger and SOX 404  certification,  we've taken
steps to  refine  our  corporate  inventory  policy,  which  resulted  in larger
reserves.

                                      * * *

Nanometrics is in the best competitive  shape ever, and we are looking for paths
to further growth. As you may have read, last month, we announced our intentions
to merge with August  Technology.  The Company and the Board have long  believed
that the  complementary  merger  would be one of the ways to expand our  product
line and global service footprint. For its part, August presents an ideal merger
opportunity  to  bring 2  strong  companies  together  to  form a  substantially
stronger provider of world-class metrology and inspection solutions.

Notwithstanding    recent   announcements    regarding    alternative   proposed
transactions,  August  Technology and Nanometrics  remain fully committed to our
merger plan and are proceeding forward. The Hart-Scott-Rodino regulatory filings
have been filed,  and the clock is ticking.  We believe the initial  shareholder
proxy in the form of an S-4 will be delivered  to the SEC in early March.  After
the S-4 is filed, we will need to wait for SEC comments before proceeding. There
is no way of  estimating  whether  the SEC will  make  comments  or how long the
process  might take,  if they do. The best case  estimate on the deal closing is
early May. We remain hopeful that we can quickly  execute on a transaction  that
is in the  interests  of both  companies'  shareholders.  Getting  this  process
completed as quickly as possible and minimizing  disruption to our business is a
top priority.

Why is this merger so important?  We believe the August/Nanometrics  merger will
be good for the  semiconductor  industry,  our customers and our  investors.  We
expect the combined August/Nanometrics to provide a broad array of front-end and
final  manufacturing  inspection and metrology  equipment that will offer better
alternatives  for its customer  base.  That means more choices.  We believe that
keeping alive a competitive  environment in metrology inspection is good for the
industry and good for our investors.



Both companies believe that the challenges to small, innovative providers in our
industry  have never been  greater.  While often  producing  the best new ideas,
small and mid-sized  companies in the capital equipment industry today work very
hard to serve the increasing global needs to meet their financial responsibility
as public companies, particularly in this era of Sarbanes-Oxley, and to reinvest
in leading-edge  R&D that can move  technology  forward.  In these times,  smart
combinations  like the  August/Nanometrics  merger can  produce  the  technical,
financial  and  infrastructure  critical  mass needed to serve our customers and
shareholders better without sacrificing our innovative cultures.

As we move forward on this transaction,  there has certainly been disruption and
confusion created by some of our competitors. We can't really speak to specifics
on those  issues  other  than to say that we  believe  our deal  provides  great
opportunity  for both companies and August  management will continue to evaluate
all  potential  options.  We can't give you guidance into what others may do and
repeat that we have a deal in place today that we are -- that we fully intend to
execute.

These are certainly heady times for us. Coming off a year of record  performance
and bolstered by the continued  success of our highly  differentiated  products,
Nanometrics is positioned for further growth and success.

                                      * * *

Having gone through all those key highlights and comments, I will now open it up
to questions. Operator?

QUESTION AND ANSWER

                                      * * *

Stephen Dan (ph) of HMC (ph) New York.

Good morning. I have a question.  I am a large  shareholder,  both of August and
also of  Nanometrics,  and your offer to us right now is worth  about  $7.30.  I
understand  it's going to be a great  combination  but how can I justify this to
myself and to my fiduciaries that I have a responsibility to -- to vote for your
deal?

John Heaton - Nanometrics - President, CEO

Well,  there is no single  answer to that  question  I can give you.  We are not
looking at a trade on the market;  what we're looking  about is creating  future
earnings for the 2 sets of  shareholders  that we think having those 2 companies
together will provide a better long-term  investment for our  shareholders  than
you might be indicating  today.  I mean, if you wanted to have a price today for
your shares,  you could  certainly sell your August shares at quite a premium to
what our offer is today.




On the other  hand,  if you're  looking to a much  better  picture for the share
price  in the  future,  we think  that the  potential  remains  for our  company
combined  to provide  that to you.  That has been our  philosophy  from the very
beginning.  It's not about  where  the stock  prices  are at today;  it's  about
putting 2 companies  together  and  creating a really  compelling  company  that
provides great shareholder value and earnings into the future.

Stephen Dan - HMC (ph) New York - Analyst

Well, I just don't believe that you're going to be able to get a positive  vote,
going forward,  when you put out the proxy. I think you're going to just have to
justify  a  higher  price  and  when  you're  dealing   against  a  much  larger
organizations such as KLA, who is a huge organization  versus yourself,  I don't
see how you can get around that. Can you explain that to me?

John Heaton - Nanometrics - President, CEO

Well,  number one, you'd have to really take that up with the August  management
and not the  Nanometrics  management.  I mean, they are the ones that have a KLA
offer,  not us. So we have a deal with  August.  We maintain  that it was a fair
deal for both sets of  shareholders,  and we will make our  presentation  to the
shareholders  and hope that they believe that the combined  company will provide
the kinds of performance in the future that we expect.

Stephen Dan - HMC (ph) New York - Analyst

Well,  as a  shareholder,  as I told you,  of both  companies,  and I am a large
shareholder  of both, I feel that KLA has made a much better offer than you have
for August.

John Heaton - Nanometrics - President, CEO

Like I said, that's not for Nanometrics to decide and --.

Stephen Dan - HMC (ph) New York - Analyst

Well,  if  Nanometrics  wants to buy this  company  and go  forward  and get the
synergies out of it, I think it is something for you to consider.

John Heaton - Nanometrics - President, CEO

Well, I think it's very clear and I think the August folks have made it clear as
well that August is not for sale.  August has placed a  strategic  merger on the
table with Nanometrics.  The company has not been for sale.  They've  maintained
that over and over again, and nobody seems to understand that concept. These are
2 companies that operate  independently  that want to join  together,  that will
create a more significant entity to provide greater  shareholder  value.  That's
the  direction  that we're  going.  Now, if August is for sale,  then that would
change, but --.




Stephen Dan - HMC (ph) New York - Analyst

Well,  I  understand  that,  but you are using the word "not for sale" in a very
nebulous  way.  However,  it  sure  looks  like  it's  up for  sale  for me as a
shareholder.

John Heaton - Nanometrics - President, CEO

Like I said,  if you have issues  relative to your shares of August,  that's for
you to take up with them, not with us.

Stephen Dan - HMC (ph) New York - Analyst

Why don't you just  offer us a better  ratio if you really  want to acquire  the
company?

John Heaton - Nanometrics - President, CEO

We have a deal on the table, sir, and I think that's all we can say about it. So
I would proceed to the next question, operator.

Also,  I've been aware that you don't really give  forward-looking  guidance and
you don't really give  guidance to the Street.  It seems to me that you guys are
coming in with your best  numbers  ever,  with  substantial  top-line as well as
bottom-line  growth and an enormous  turnaround as well. You are to be applauded
for that but to some  extent,  it's being viewed as a negative,  maybe  somewhat
explained away by the write-down  that might have been  unexpected but by a much
higher Street  number.  Do you plan on trying to work more  cohesively  with the
Street,  going forward,  in terms of, you know, better guidance and so everybody
is more online?  Because I would've  thought that,  given these type of numbers,
that the news this morning would have been hey great rather than  disappointment
per se,  which I view the  Company as a whole as going  forward  and  everything
across the board to be positive,  especially  some of the things you're  sharing
today.  But what's  your  thoughts  on that in terms of sharing  with the Street
going forward?

John Heaton - Nanometrics - President, CEO

So, I want to speak to that because I think there's a couple of issues that need
to be taken into consideration.  You are absolutely right that we have not given
EPS guidance to the Street.  We've always had a certain  amount of complexity in
trying to do that  because of all of these other  factors that usually come into
play.  On the  other  hand,  I  think  one of  things  you  have  to  take  into
consideration, even though we gave and met our guidance and as you said, we feel
very positive about 18 cents per share and (indiscernible) if you look at one or
the other competitors for August, we are a 50 percent higher EPS basis than them




and our stock is trading at a huge  discount  to theirs and you've got to say to
yourself wow, Nano is growing at 70 percent,  they are producing better earnings
at the bottom line, yet we are getting heavily discounted in the market. I don't
know whether it's an arbitrage issue or not but it certainly is probably related
somewhat at least to the perceived myth on the EPS.

You know,  one of things you have to take into  consideration  is that we did go
through an auditor change this year and as we go through that complication,  you
have to go back and re-examine the things that you do,  bringing up to speed and
trying  to  educate  both  sides on what it best  (indiscernible)  policies  and
procedures are. There's no way that we could have  forecasted,  in the beginning
of Q4, that we did have  issues  relative  to  inventory.  As I said also in the
prepared  remarks,  we now have a 2-year  window  on our ERP  system  and  we're
getting tremendous  visibility now into the inventory parts that are moving, how
they are  moving,  when they move.  These are the kind of metrics  that we never
really  had at our  disposal  in the  past.  So  what  we're  using  this  is an
opportunity to go back and refine our policy, which has not changed; it's just a
refinement -- saying we've got more  information  now, we can do a better job of
monitoring and maintaining our process for looking at the inventory, and we kind
of view that as a major positive going forward. So, we shouldn't see these kinds
of issues come up again because we are going to have a much better handle on it.

Having  said all of that,  you know,  I don't  know that we will  change our EPS
policy at this point.  We  potentially  can do a better job if we get maybe even
the critical mass associated with being with August,  if we have a larger,  more
stable  revenue  base and I think an overall  better  picture on where the costs
are. I think  small  incremental  changes in the  quarter  would be more easy to
predict if we were of a larger financial critical mass.

So, if we do get  together,  I think that will  probably be in the cards.  If we
don't, then obviously any one of these events that occur in a quarter can have a
substantial  impact on our EPS and can cause misses.  So I'm not really sure, at
this  moment,  that we can tell you that  things  are  going to  improve  from a
forecasting  standpoint,  other than we've done a pretty good job of maintaining
our  guidance  on revenues  and we hope to  continue  that and hope that the EPS
follow more in line with expectations into the future.

Alexander Nockman - Montauk Financial Services - Analyst

Okay,  great.  One last  question  -- with  regards to the  August  Technology's
merger,  can you comment on whether or not you feel that this  situation,  if it
does close let's say in the second  quarter of '05, will be accretive  this year
versus any type of expenses you may bear with it across the board?

John Heaton - Nanometrics - President, CEO

It's almost  impossible to know. I would say that,  within a year, that would be
the goal for the combined company.  Whether it can happen within calendar '05 is
a major  question  mark  because  the longer this thing gets  delayed,  the less
opportunity  you have to resolve the 2 companies.  So until we get to the close,
it's impossible to predict,  but we certainly intend to get this thing on a very
positive note as quickly as possible.

Ben Stoller - Hibernia Southcoast Capital - Analyst

Most of the business  questions  have been asked and actually,  since you opened
the door on the  Nano/August,  as a shareholder  of Nano, how much money have we
spent on this process and how much do we intend to spend on this process?  It is
obvious the market  doesn't think it's going to happen.  If there's such a great
disparity  in the  multiples  between  where we are trading and where  August is
trading, why doesn't it make sense for August to buy us? (LAUGHTER).  Really, it
doesn't make sense.  Our stock  continually  -- you know,  we're under  pressure
here.  Where is the  focus  with the  upper  management?  We have to spend  time
running the business,  not running after an asset that it's obvious we can't get
or that is trading at $4 through the price?

John Heaton - Nanometrics - President, CEO

Yes. We don't have -- we don't  accumulate the costs  associated  with doing the
deal because  obviously there's lots of people working on it at this point. That
would be done at the end of the  process,  as  opposed  to kind of --  (multiple
speakers) -- process.

Ben Stoller - Hibernia Southcoast Capital - Analyst

Right, and you would capitalize those, right?

John Heaton - Nanometrics - President, CEO

Sure. We will take a one-time write-off, so we are not going to be incorporating
them in the Q4 or Q1 numbers or any along those lines.  So, what are we going to
do? You know, obviously,  as you say, we are trading at quite a discount to both
August  and to KLA and to  Rudolph.  I think the best thing that we can do is go
out and tell people about the story and  highlight  the issue that we -- you see
obviously and we see,  which is that we are trading at a much lower multiple for
some unknown reason.  We are providing the growth, we are providing the earnings
and we're not being rewarded for it.

Ben Stoller - Hibernia Southcoast Capital - Analyst

Well, I think the reason is obvious -- that August is for sale. You say they are
not, but they are. They agreed to sell themselves to us, so that's the disparate
in the multiples.  Just looking or --  (indiscernible)  that's what's built into
their price. So I don't know if it's a fair one-on-one multiple comparison,  but
you know -- and before you said,  you know, the  shareholders  will get the vote
for the transaction, correct?




John Heaton - Nanometrics - President, CEO

That's correct.

Ben Stoller - Hibernia Southcoast Capital - Analyst

Okay, so basically  the  shareholders  run the company,  so we will decide if we
want to buy them or not through a vote.  You know,  just  strategy or not but if
the multiples are just so disparate, maybe it doesn't make sense to do it.


John Heaton - Nanometrics - President, CEO

Right,  I mean,  that's going to be up to the  shareholders  ultimately,  and we
can't -- you know,  like I said,  our objective in the Company is to provide our
shareholders  with the best growth  going  forward.  We believe that this is the
best thing for our  shareholders.  We  maintain  that.  We believe  August  also
maintains that. We're going to try to take it to a vote unless something happens
between  now and that  vote.  We  maintain  that  it's the best  thing  for both
companies and that we will proceed down this path in a very positive way.

Ben Stoller - Hibernia Southcoast Capital - Analyst

Well  obviously  we're  going  to vote for it. I mean if we can buy them at a $4
discount to where it is trading in the marketplace,  we will do it all day long,
so I don't think that's the issue.  The issue is do we take our eye off the ball
and try to pursue  this,  or do we get back on track,  on point and make sure we
run the Company the way we want it run?

John Heaton - Nanometrics - President, CEO

Well,  we are running the  Company  the way we want it run.  Actually,  now that
we've gone through the negotiation process, we are --.

Ben Stoller - Hibernia Southcoast Capital - Analyst

While incurring significant costs as well.

John Heaton - Nanometrics - President, CEO

But if the deal does not go through,  if you read the proposed merger agreement,
then you'll find that those costs are recoverable.




Ben Stoller - Hibernia Southcoast Capital - Analyst

Okay.

John Heaton - Nanometrics - President, CEO

So going forward,  it's a great  situation,  I think, for our  shareholders.  No
matter what  happens,  I think we're going to go forward in a very positive way,
and we are totally  hopeful that we can merge with August and that,  like I said
before,  that we provide our customers and our shareholders and employees with a
great future and a great  company.  I think  there's a tremendous  demand on the
customer  side to make that happen.  You know,  if I look at -- if you go beyond
Wall  Street and what  people are saying  about the stocks and the trade and you
listen to what the  customers  are  saying,  you are  going to get a  completely
different  picture on this  merger  for them.  Many of our major  customers  and
August  customers  absolutely want to see this merger going forward because they
want to see a stronger  metrology  company out there; they don't like to have so
much of only one  large  company  and a lot of small  ones.  They  want to see a
consolidation;  they want to see strong  alternatives  with good  technology and
cultures.  They don't  necessarily  have that today.  In fact, when they have to
make  choices  about  metrology,  they are to some extent stuck with go with the
guerrilla or go with a smaller  company that induces some risk in their company.
They don't like that in general.  So there's been a tremendous  support from our
customers.  We'd  like to see that  play out in the  stock,  which it has not up
until this point.  We think that, if this thing does go forward,  that they will
support the new company even stronger than they would had it not happened.  So I
think there's all kinds of major positives going forward if we can get this deal
done.

Ben Stoller - Hibernia Southcoast Capital - Analyst

I concur  and I look  forward  to it. I just don't know if we can get it done at
this price. It seems impossible the way it's trading. But no, I agree, if we can
buy it at this price, we will buy it all day long. That's why we support it.

John Heaton - Nanometrics - President, CEO

The vote is not today. I think everyone has to kind of wait.  It's very early in
the process still. We still have a long way to go.

Ben Stoller - Hibernia Southcoast Capital - Analyst

Right. I mean,  earlier, I was on listening on the call and some shareholder - a
shareholder got on and said he owned August  Technologies and said basically why
would he take this $4 discount  towards  trading on the market?  I would have to
agree with him, if I owned August. I just wouldn't do the deal.

John Heaton - Nanometrics - President, CEO

Yes, I  understand  everyone's  perspective  and I  appreciate  and  respect all
opinions.  Again,  we go back and we maintain  that this is a fair deal for both
sides,  regardless  of where the  stocks are  trading at today.  When we did the
deal, they were trading in a certain range. All of the understandings of EPS and
revenue and growth were all taken into consideration, and here we are now.




Ben Stoller - Hibernia Southcoast Capital - Analyst

Sure,  sure.  Also too, as you said,  let's make sure we get our fee if the deal
breaks too.  Maybe it's more  prudent just to take our fee and move on and focus
in on our  business  if we can't  get it at the  price  that we want.  It's very
difficult toe-to-toe, as you say, with the guerrilla in the space.

John Heaton - Nanometrics - President, CEO

I can't really speak to those  things,  as I said in my comments.  It is what it
is. We're doing our deal.

Ben Stoller - Hibernia Southcoast Capital - Analyst

How much per share is the breakup fee?

John Heaton - Nanometrics - President, CEO

I don't know what it is per  share.  If you look at the  document,  I think it's
$8.3 million for us.

                                      * * *
