                       Advanced Technology Materials, Inc.
               Notes To Consolidated Interim Financial Statements
                                   (unaudited)

1. Basis of Presentation

     The  accompanying   unaudited  interim  financial  statements  of  Advanced
Technology  Materials,  Inc.  ("ATMI" or the  "Company")  have been  prepared in
accordance  with the  instructions to Form 10-Q and Rule 10.01 of Regulation S-X
and do not include all of the financial  information and disclosures required by
generally accepted accounting principles.

     In the  opinion of the  Company's  management,  the  financial  information
contained herein has been prepared on the same basis as the audited Consolidated
Financial  Statements  contained in the  Company's  Form 10-K for the year ended
December 31, 1996, and includes adjustments (consisting only of normal recurring
adjustments)  necessary to present  fairly the unaudited  quarterly  results set
forth herein. The Company's quarterly results have, in the past, been subject to
fluctuation and, thus, the operating results for any quarter are not necessarily
indicative of results for any future fiscal period.

2. Per Share Data

     Earnings per common share is computed using the treasury stock method based
on  the  weighted  average  number  of  common  and  common   equivalent  shares
outstanding  during the period.  Shares from the assumed exercise of options and
warrants  granted  by the  Company  have been  included  in the  computation  of
earnings  per  share  for  all  periods,   unless  their   inclusion   would  be
antidilutive.

     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128,  Earnings  per Share,  which is required to be adopted on December  31,
1997. This Statement  simplifies the computation of earnings per share and makes
the   computation   more  consistent   with  those  of  other   countries.   The
implementation  will require the  disclosure  of basic and diluted  earnings per
share.  The Company will adopt this Statement during the fourth quarter of 1997.
Pro forma basic earnings per share under the new  computation  are $.15 and $.28
for the three months and six months ended June 30, 1997, respectively.

3. Inventory

Inventory is comprised of the following:


                                           June 30,              December 31,

                                          ==========             ==========








4. Income taxes

     ATMI's  income  tax  expense  relates  primarily  to state  taxes on income
generated,  partially  offset  by the  utilization  of  loss  carryforwards  and
available  state tax credits.  Minimal  federal taxes in 1997 and 1996 relate to
alternative   minimum  taxes  arising  from  the  use  of  net  operating   loss
carryforwards.  ATMI has utilized  substantially  all its federal net  operating
loss carryforwards as of June 30, 1997.

5. Mergers and Acquisitions

     On April 7, 1997, the Company executed a Merger and Exchange Agreement (the
"ADCS Agreement") to acquire all of the issued and outstanding  equity interests
in Advanced  Delivery & Chemical  Systems Nevada,  Inc. and its related entities
("ADCS").  ADCS is  engaged in the  manufacture  and sale of  ultra-high  purity
semiconductor  thin film materials and  associated  delivery  systems.  The ADCS
Agreement is subject to approval by ATMI's  stockholders and the satisfaction of
other customary  conditions.  Transaction costs of approximately $2 million will
be recognized in the period the transaction closes.

     Pursuant to the ADCS  Agreement,  holders of interests in ADCS will receive
between  5,468,750  and  6,250,000  shares  of common  stock of a newly  created
holding company in exchange for their interests.  The actual number of shares to
be issued to the holders of equity  interests  in ADCS  depends upon the average
closing price of ATMI's common stock during a 20 day trading  period ending five
days prior to stockholder approval of the ADCS Agreement.  Additionally, as part
of the transaction,  ATMI will become a subsidiary of the holding  company.  The
acquisition  is intended to be  accounted  for as a pooling of  interests.  ATMI
intends to continue  the  business  currently  performed by ADCS by combining it
with the  semiconductor  thin  film and  delivery  system  product  lines of the
NovaMOS division of ATMI, under the name ADCS.

     On May 17, 1997, the Company, executed an Agreement and Plan of Merger (the
"LSL Agreement") to acquire all of the issued and outstanding  stock in Lawrence
Semiconductor  Laboratories,  Inc.  ("LSL").  LSL is an  outsourcer of epitaxial
processing of silicon wafers using chemical vapor deposition  technology to meet
customer  specifications.  Epitaxial processing is one of many steps involved in
transforming a silicon wafer into a semiconductor  chip, the primary  functional
component of most electronic products.  The LSL Agreement is subject to approval
by ATMI's  stockholders  and the  satisfaction  of other  customary  conditions.
Transaction  costs of approximately  $1.5 million are expected to be recognized.
Additionally,  LSL would incur a fee of approximately $750,000 to its investment
banker  and  a  break-up  fee  in  connection   with  another   transaction   of
approximately  $1.8 million upon  consummation of the acquisition of LSL. All of
these  non-recurring  costs will be  recognized  in the  period the  transaction
closes.

     Pursuant to the LSL  Agreement,  stockholders  in LSL will receive  between
approximately 3,714,285 and 4,588,235 shares of common stock of ATMI (or a newly
created holding company if the pending  acquisition of ADCS and related entities
is consummated) in exchange for their shares.  The actual number of shares to be
issued to the LSL stockholders  depends upon the average closing price of ATMI's
common  stock  during  a 20 day  trading  period  ending  three  days  prior  to
stockholder  approval of the LSL  Agreement and changes in the net book value of
LSL up to the time of closing.  The  acquisition is intended to be accounted for
as a pooling  of  interests.  The  Company  intends  to  continue  the  business
currently  performed by LSL by combining it with its  Epitronics  division which
provides epitaxial services for gallium arsenide and other advanced materials.

     As of June 30, 1997, approximately $1,430,000 of non-recurring  transaction
costs have been  classified on the balance  sheet as other current  assets until
the aforementioned transactions close.


     Item 2.  Management's  Discussion  and Analysis of Financial  Condition and
Results of Operations

     Overview  Founded in 1986,  ATMI generates  revenues from product sales and
contract research. Most product sales are point-of-use  environmental equipment,
specialty materials,  and delivery systems for the semiconductor  industry. ATMI
also receives royalties for certain product sales from third parties.

     Since  1986,  a  significant  portion  of  ATMI's  revenues  has come  from
contracts  with United States  government  agencies.  The programs in which ATMI
participates  may extend for several  years,  but are usually  funded  annually.
There can be no assurance  that the  government  will continue its commitment to
programs to which ATMI's  development  projects are  applicable or that ATMI can
compete successfully to obtain program funding.

     ATMI has  used a  targeted  acquisition  strategy  to  assist  in  building
critical  mass and market  position in the niches the Company  serves.  In 1994,
ATMI acquired Vector Technical Group, Inc.  ("Vector"),  and in conjunction with
the sale of certain Novapure product lines to Millipore Corporation in September
1994,  formed  ATMI  EcoSys  Corporation  ("EcoSys")  by  merging  the  retained
operations of Novapure with those of Vector. In 1995, ATMI acquired the Guardian
product line from Messer Griesheim Industries, Inc. and folded that product line
into EcoSys. In 1995, ATMI acquired Epitronics  Corporation,  and in early 1996,
combined  that business with the formerly  known  Diamond  Electronics  division
under the Epitronics  name. In April 1997 and May 1997, ATMI announced  intended
acquisitions  of ADCS and LSL.  ADCS  manufactures  and  distributes  ultra-high
purity  semiconductor  thin film  materials.  LSL is an  outsourcer of epitaxial
processing of silicon wafers using chemical vapor deposition  technology to meet
customer specifications. ATMI intends to combine the operations of ADCS with the
operations of ATMI's NovaMOS  division and to combine the operations of LSL with
the operations of ATMI's Epitronics division following  shareholder  approval of
these transactions, which is anticipated during the third quarter of 1997.

     The following table sets forth, for the periods  indicated,  the percentage
relationship to total revenues of certain items in ATMI's Consolidated Statement
of Operations:

Results of Operations

Three Months Ended June 30, 1997 and 1996.

     Revenues.  Total revenues  increased 10.1% to approximately  $13,632,000 in
the three months ended June 30, 1997 from approximately  $12,376,000 in the same
three month period in 1996.  Product  revenues  increased 11.7% to approximately
$11,350,000  in  the  three  months  ended  June  30,  1997  from  approximately
$10,164,000  in the comparable  period in 1996.  The product  revenue growth was
primarily attributable to the continued expansion of SDS product sales. Contract
revenues,  which  are  funded  solely  by  United  States  government  agencies,
increased  3.2% to  approximately  $2,282,000 in the quarter ended June 30, 1997
from  approximately  $2,212,000  in the same  three  month  period in 1996.  The
increase in the 1997 quarter reflects a general  increase in government  funding
of the Company's research activities.

     Gross Profit.  Gross profit increased 14.9% to approximately  $7,032,000 in
the quarter  ended June 30, 1997 from  approximately  $6,122,000  in the quarter
ended June 30, 1996.  As a percentage  of  revenues,  gross margin  increased to
51.6% in the three  month  period in 1997 from  49.5% of  revenues  in the three
month period in 1996.

     Gross  profit  from  product  revenues  increased  14.2%  to  approximately
$6,631,000 in the three months ended June 30, 1997 from approximately $5,806,000
in the same three month period a year ago. As a percentage of product  revenues,
gross margin increased to 58.4% in the 1997 period from 57.1% in the 1996 period
due  principally  to higher margin on the product mix within the EcoSys  product
lines.

     Gross profit on contract revenues increased 26.9% to approximately $401,000
in the  quarter  ended June 30,  1997 from  approximately  $316,000  in the same
quarter a year ago. As a percentage of contract revenues, gross margin increased
to 17.6% in the first  quarter of 1997 from 14.3% in the first  quarter of 1996.
Contract  margins  can  vary  slightly  from  year to year  based  on the mix of
cost-type, firm fixed price and cost share arrangements. Additionally, different
fee   arrangements  and  indirect  cost  absorption  can  contribute  to  margin
variability.

     Research  and  Development  Expenses.  Research  and  development  expenses
decreased  0.5% to  approximately  $2,174,000  in the first three months of 1997
from  approximately  $2,185,000  in the first three months of 1996.  This slight
decrease was attributable to the corresponding  increase in government  contract
revenues for the quarter which funded a slightly larger portion of the Company's
research  expenses.  As a  percentage  of  revenues,  research  and  development
expenses decreased to 15.9% in the 1997 quarter from 17.7% in the 1996 quarter.

     Selling,  General  and  Administrative   Expenses.   Selling,  general  and
administrative expenses increased 3.8% to approximately  $3,470,000 in the three
months  ended March 31,  1997 from  approximately  $3,344,000  in the same three
month  period in 1996.  The increase in the 1997  quarter was  primarily  due to
increased  administrative  costs related to an increase in headcount,  including
expenses related to the ISO 9000 certification  process underway at the Company.
As a percentage  of  revenues,  these  expenses  decreased to 25.5% in the three
month period in 1997 from 27.0% in the comparable period in 1996.

     Other Income,  Net. Other income increased 35.1% to approximately  $177,000
in the quarter  ended June 30, 1997 from  approximately  $131,000 in the quarter
ended June 30, 1996.  The increase in the 1997 quarter  related to a decrease in
interest expense as a result of decreases in outstanding debt balances.

     Income Taxes. ATMI's income tax expense related primarily to state taxes on
income generated,  partially offset by the utilization of loss carryforwards and
available state tax credits. Minimal federal taxes paid in 1997 and 1996 related
to  alternative  minimum  taxes  arising  from  the  use of net  operating  loss
carryforwards.  Income  tax  expense  in the  quarter  ended  June 30,  1997 was
$226,000 up from  $84,000 in the same  quarter a year ago.  The  Company's  loss
carryforwards  have  been  substantially  utilized  at June  30,  1997,  causing
effective tax rates to increase.  The Company  expects the tax rates to approach
approximately 40% by the end of the current year.

     Earnings  per  Share.  Earnings  per share  improved  to $.14 for the first
quarter of 1997  compared with a $.07 earnings per share in the first quarter of
1996.  Earnings  per share in the 1997  period  reflects  the 2.2%  increase  in
weighted average shares  outstanding from  approximately  9,413,000 in the first
quarter of 1996 to  approximately  9,618,000  in the first  quarter  of 1997,  a
result of exercised  stock options under the Company's  existing stock plans and
the  dilutive  effect of a higher  stock  price when  calculating  common  stock
equivalents.

Six Months Ended June 30, 1997 and 1996.

     Revenues.  Total revenues  increased 16.3% to approximately  $26,098,000 in
the six months ended June 30, 1997 from  approximately  $22,438,000  in the same
six month period in 1996.  Product  revenues  increased  19.5% to  approximately
$21,197,000 in the six months ended June 30, 1997 from approximately $17,744,000
in the  comparable  period in 1996.  The product  revenue  growth was  primarily
attributable  to the  continued  expansion of SDS product sales and higher sales
levels at EcoSys. Contract revenues, which are funded by United State government
agencies,  increased  4.4% to  approximately  $4,901,000 in the six months ended
June 30,  1997 from  approximately  $4,695,000  in the same six month  period in
1996.  The  increase in the six months  ended June 30, 1997  reflected a general
increase in government funding of the Company's research activities.

     Gross Profit. Gross profit increased 16.8% to approximately  $12,729,000 in
the six months  ended June 30, 1997 from  approximately  $10,902,000  in the six
months ended June 30, 1996. As a percentage of revenues,  gross margin increased
to 48.8% in the six month period in 1997 from 48.6% of revenues in the six month
period in 1996.

     Gross  profit  from  product  revenues  increased  17.1%  to  approximately
$11,868,000 in the six months ended June 30, 1997 from approximately $10,136,000
in the same six month  period a year ago. As a percentage  of product  revenues,
gross margin decreased to 56.0% in the 1997 period from 57.1% in the 1996 period
due  principally  to product mix  variability  within the EcoSys  product  lines
offset by  manufacturing  margins on SDS product sales which are at a level that
is higher than the average ATMI product margin. Prior to November 1996, revenues
for the SDS product line consisted of royalty payments.

     Gross profit on contract revenues increased 12.5% to approximately $862,000
in the six months  ended June 30, 1997 from  approximately  $766,000 in the same
quarter a year ago. As a percentage of contract revenues, gross margin increased
to 17.6% in the first quarter of 1997 from 16.3% in the first quarter of 1996.

     Research  and  Development  Expenses.  Research  and  development  expenses
increased 1.6% to approximately  $4,112,000 in the first six months of 1997 from
approximately  $4,048,000 in the first six months of 1996. Increased development
efforts surrounding the Company's ferroelectric thin film technology and related
applications was the primary cause for the increase, offsetting reduced spending
related to other technology  development  efforts.  As a percentage of revenues,
research and development  expenses  decreased to 15.7% in the first half of 1997
from 18.0% in the first half of 1996.

     Selling,  General  and  Administrative   Expenses.   Selling,  general  and
administrative  expenses  increased 4.5% to approximately  $6,189,000 in the six
months ended June 30, 1997 from  approximately  $5,920,000 in the same period in
1996.  The increase in the 1997 period was primarily due to increased  corporate
administrative   costs,   increased  product  shipments  and  increased  product
marketing  activity.  As a percentage of revenues,  these expenses  decreased to
23.7% in the first half of 1997 from 26.4% in the comparable period in 1996.

     Other Income,  Net. Other income increased 22.0% to approximately  $350,000
for the six months  ended June 30, 1997 from  approximately  $287,000 in for the
six months  ended June 30,  1996.  The  increase in the first six months of 1997
related  to  a  decrease  in  interest  expense  as a  result  of  decreases  in
outstanding debt balances.

     Income Taxes. ATMI's income tax expense related primarily to state taxes on
income generated,  partially offset by the utilization of loss carryforwards and
available state tax credits. Minimal federal taxes paid in 1997 and 1996 related
to  alternative  minimum  taxes  arising  from  the  use of net  operating  loss
carryforwards.  Income tax  expense  for the six months  ended June 30, 1997 was
$332,000, up from $112,000 in the same six months a year ago. The Company's loss
carryforwards have been substantially  utilized,  causing effective tax rates to
increase.  The Company  currently  estimates its tax rates to approximate 40% by
the end of the current year.

     Earnings per Share.  Earnings per share improved to $.26 for the six months
ended June 30, 1997  compared  with a $.12 earnings per share for the six months
ended June 30,  1996.  Earnings  per share in the 1997 period  reflects the 2.3%
increase in weighted average shares outstanding from approximately  9,364,000 in
the first six months of 1996 to approximately  9,584,000 in the first six months
of 1997, a result of exercised stock options under the Company's  existing stock
plans and the dilutive  effect of a higher stock price when  calculating  common
stock equivalents.


Liquidity and Capital Resources

     Net cash used by  operations  was  approximately  $662,000  during  the six
months ended June 30, 1997 compared to $2,029,000  provided  during the same six
month period of 1997,  despite generating  approximately  $1,336,000 more of net
income in the six month period ended June 30, 1997 than the preceding year's six
month period  ended June 30, 1996.  Working  capital  fluctuations  in the first
quarter of 1997 resulted in a significant  use of cash,  primarily  increases in
accounts  receivable,  and other assets which were partially offset by increases
in accounts  payable and accrued  expenses.  The Company has used a  significant
amount of cash for transaction  costs  associated with the pending mergers noted
above.  These  costs will be  expensed  in the period in which the  transactions
close.









     The  Company  utilized  approximately   $2,362,000  in  cash  in  investing
activities  compared to a generation of approximately  $2,299,000 in cash in the
same quarter a year ago.  During the first six months of 1997, cash was used for
the purchase of approximately $2,200,000 in capital equipment, primarily related
to installation of SDS manufacturing  capacity in Danbury and epitaxial capacity
at Epitronics'  Phoenix facility.  In the previous year's first six months,  the
Company incurred approximately $2,500,000 in capital expenditures and sold a net
amount of approximately $4,800,000 in marketable securities.

     The Company utilized approximately $75,000 from financing activities during
the first six months of 1997 compared to a utilization of cash of  approximately
$3,606,000  in the first  six  months  of 1996.  The  first  six  months of 1996
included a $4 million debt payment  related to the Company's  acquisition of its
Guardian line of environmental equipment.

     ATMI  believes  its  existing  cash  balances  and  marketable  securities,
together  with  existing  sources  of  liquidity  and  anticipated   funds  from
operations,   will  satisfy  its  projected   working  capital  and  other  cash
requirements through at least the end of 1998. However,  ATMI believes the level
of financing resources available to it is an important competitive factor in its
industry  and may  seek  additional  capital  prior  to the end of that  period.
Additionally,  ATMI considers,  on a continuing basis, potential acquisitions of
technologies  and  businesses  complementary  to its current  business which may
require additional cash.
