1.   ORGANIZATION, BUSINESS AND BASIS OF PRESENTATION

     Organization and Business

     Cepheid (the  "Company")  was  incorporated  in the State of  California on
March 4, 1996. The Company is  commercializing  its I-CORE(R)  microfluidic  and
microelectronic  technologies  as the  preferred  platform  for  rapid,  on-site
detection of DNA (or RNA) in complex biological samples for scientific,  medical
and industrial  applications.  The Company is developing fast, versatile systems
that can  perform all the steps  required  to analyze DNA in complex  biological
samples - sample preparation, amplification and detection - with results in less
than 30 minutes on a single instrument.

     The accompanying unaudited condensed consolidated financial statements have
been prepared by management in accordance  with  generally  accepted  accounting
principles for interim financial  information and with the instructions for Form
10-Q and Article 10 of Regulation S-X. Accordingly,  they do not include certain
information and footnotes normally included in financial  statements prepared in
accordance with accounting  principles  generally accepted in the United States.
In the opinion of management,  all adjustments  (consisting of normal  recurring
entries)  considered  necessary  for a fair  presentation  have  been  included.
Operating  results for the three and six month  periods  ended June 30, 2001 are
not  necessarily  indicative  of the results  that may be expected  for the year
ending  December  31,  2001 or for any other  future  period.  The  accompanying
financial statements should be read in conjunction with the audited consolidated
financial  statements  and notes thereto  included in our Form 10-K for the year
ended December 31, 2000 filed with the Securities and Exchange Commission.

2.   SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation

     The  consolidated  financial  statements of Cepheid include the accounts of
the  Company  and its  wholly-owned  subsidiary.  All  significant  intercompany
balances and transactions have been eliminated.

     Revenue Recognition

     The Company  recognizes  revenue from product sales when goods are shipped,
when there is  persuasive  evidence  that an  arrangement  exists,  delivery has
occurred, the price is fixed and determinable,  and collectibility is reasonably
assured. No rights of return exist for product sales.

     Contract  revenues  related  to  best  efforts,  research  and  development
agreements  and  government  grants are  recognized as the related  services are
performed.  Revenue  is  earned  based on the  performance  requirements  of the
contract.   Non-refundable  contract  fees  for  which  no  further  performance
obligations  exist, and there is no continuing  involvement by the Company,  are
recognized  on the earlier of when the payments are received or when  collection
is assured. Under these agreements,  the Company is required to perform specific
research  and  development  activities  and is  reimbursed  based  on the  costs
associated with each specific contract over the term of the agreement. Milestone
related revenues are recognized upon the achievement of the specified milestone.
Deferred  revenue is recorded  when funds are received in advance of services to
be performed.

     Significant Concentrations

     We  distribute  our  products  through  our direct  sales force and through
third-party  distributors.  Product  revenue from our three  distributors,  each
representing 10% or more of total sales, was 26% for Fisher  Scientific  Company
L.L.C.,  37% for Takara  Shuzo Co. Ltd. and 27% for  Eurogentec  for the quarter
ended June 30, 2001. For the same quarter of the previous  year,  Fisher was 57%
and Takara and Eurogentec were zero.

     The  Company  relies on  several  companies  as the sole  source of various
materials in its manufacturing  process. Any extended interruption in the supply
of these materials could result in the failure to meet customer demand.

     Financial   instruments   that   potentially   subject   the   Company   to
concentrations of credit risk primarily consist of cash equivalent securities.

     Warranty Accrual

     We  generally  warrant our  products  from defect for a period of 12 months
from the date of sale for  material  and  labor  costs to  repair  the  product.
Accordingly,  a provision for the estimated  cost of the warranty is recorded at
the time revenue is recognized.

     Cash and Cash Equivalents

     Cash and cash  equivalents  consist of cash on deposit  with  banks,  money
market   instruments,   commercial  paper  and  debt  securities  with  original
maturities  of 90 days or less.  At June 30, 2001 and  December  31,  2000,  the
Company had approximately $32.8 million and $39.7 million, respectively, in cash
and cash equivalents.

     Inventory

     Inventory  is stated  at the lower of  standard  cost  (which  approximates
actual cost) or market, with cost determined on the first-in-first-out  ("FIFO")
method.

     Comprehensive (Income) Loss

     Comprehensive loss includes net loss as well as other  comprehensive  loss.
Cepheid's   other   comprehensive   loss  consists  of   unrealized   losses  on
available-for-sale  marketable securities. Total accumulated other comprehensive
income is  presented  as a separate  component  of  shareholders'  equity in the
accompanying Condensed Consolidated Balance Sheets.

     Recently Issued Accounting Standards

     In July 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
No.'s 141 and 142, "Business Combinations" and "Goodwill and Other Intangibles".
FASB 141 requires all business combinations  initiated after June 30, 2001 to be
accounted for using the purchase method.  Under FASB 142,  goodwill is no longer
subject to  amortization  over its estimated  useful life.  Rather,  goodwill is
subject to at least an annual  assessment for impairment,  applying a fair-value
based test.  Additionally,  an acquired  intangible  asset should be  separately
recognized  if  the  benefit  of  the  intangible   asset  is  obtained  through
contractual  or other  legal  rights,  or if the  intangible  asset can be sold,
transferred,  licensed,  rented,  or exchanged ,  regardless  of the  acquirer's
intention  to do so.  Other  intangible  assets  will  continue to be valued and
amortized over their estimated lives;  in-process  research and development will
continue to be written  off  immediately.  The Company  does not expect that the
implementation  of these statements will have a material impact on its financial
position or results of operations.

3.   NET LOSS PER COMMON SHARE

    Basic  net  loss  per  common  share  has  been  calculated   based  on  the
weighted-average  number of common shares  outstanding  during the period,  less
shares subject to the Company's right of repurchase.  Diluted net loss per share
would give effect to the dilutive effect of common stock equivalents  consisting
of stock  options and warrants  (calculated  using the treasury  stock  method).
Potentially  dilutive  securities  have been  excluded from the  computation  of
diluted net loss per share as their inclusion would be antidilutive.

The  computation  of pro forma  basic and  diluted  net loss per share  includes
shares  issuable  upon the  conversion  of  outstanding  shares  of  convertible
preferred  stock (using the as-if  converted  method) from the original  date of
issuance.

4.   ADOPTION OF SFAS 133

     Effective  January  1, 2001 the  Company  adopted  Statement  of  Financial
Accounting  Standards  (SFAS) No.  133,  "Accounting  for  Derivative  Financial
Instruments and Hedging Activities." This statement requires companies to record
derivatives  on the  balance  sheet as assets or  liabilities,  measured at fair
value. Gains or losses resulting from changes in the values of those derivatives
would be accounted  for  depending on the use of the  derivative  and whether it
qualifies  for hedge  accounting.  The adoption of the statement did not have an
impact on the  Company's  financial  position  or results of  operations  as the
Company holds no derivative financial  instruments and does not currently engage
in hedging activities.

6.   DEEMED DIVIDEND

     In  January  through  March  2000,  the  Company  consummated  the  sale of
6,379,978 shares of Series C convertible  preferred stock from which the Company
received proceeds of approximately $19.1 million or $3.00 per share. At the date
of issuance,  the Company believed the per share price of $3.00  represented the
fair  value  of the  preferred  stock.  Subsequent  to the  commencement  of the
Company's initial public offering process,  Cepheid  re-evaluated the fair value
of its common stock as of January and March 2000.  Accordingly,  the increase in
fair value has resulted in a beneficial conversion feature of $19.1 million that
has been recorded as a deemed  dividend to preferred  shareholders  in 2000. The
Company  recorded  the deemed  dividend at the date of  issuance  by  offsetting
charges and credits to additional  paid-in-capital,  without any effect on total
shareholders'  equity.  This charge was made against additional paid in capital,
as the Company did not have retained  earnings from which it could have deducted
a deemed dividend. The preferred stock dividend increases the net loss allocable
to common  shareholders  in the  calculation  of basic and  diluted net loss per
common share for the year ended  December 31, 2000.  The guidelines set forth in
the Emerging Issues Task Force Consensus No. 98-5 limit the amount of the deemed
dividend to the amount of the proceeds of the related financing.

7.   CONTINGENCIES

     On April 12,  2001,  a complaint  was filed in the United  States  District
Court for the Western  District of  Pennsylvania  by Fisher  Scientific  Company
L.L.C.,  against  Cepheid and two of our employees.  The complaint  alleges that
Cepheid's  hiring  of  two  former  Fisher  employees  violates  the  employees'
employment  agreements  with Fisher as well as Fisher's  distribution  agreement
with Cepheid, and asserts a variety of contract,  tort and trade secrets claims.
The complaint seeks declaratory relief and damages of an unspecified amount.

     There has been no discovery to date and no trial is  scheduled.  We believe
that we have  meritorious  defenses  to this  action  and if the  claims are not
withdrawn,  intend to defend them vigorously.  Based upon information  presently
known to management,  the Company is unable to determine the ultimate resolution
of this  lawsuit  or  whether  it will  have a  material  adverse  effect on the
Company's financial condition.

8.   SUBSEQUENT EVENTS

     On August 9, 2001, the Company signed a Patent and Technology Licensing and
Supply Agreement with  Environment  Technologies  Group,  Inc ("ETG"),  a wholly
owned subsidiary of Smith Industries, PLC. Under the agreement, the Company will
provide its  proprietary  I-CORE  technology to ETG for  integration by ETG into
fully automated  bio-detection  systems. In connection with this agreement,  the
Company  received an initial  license fee payment of $250,000  and will  receive
annual minimum royalty payments ranging from $50,000 to $200,000 for the life of
this agreement.  The agreement  expires upon the expiration of the legal life of
the patent rights.

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

     Certain  statements in this Form 10-Q,  including  without  limitation  the
information under the captions entitled "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Legal Proceedings,"  contain
forward-looking statements within the meaning of the federal securities laws. We
also may provide oral or written  forward-looking  statements in other materials
we release to the public from time to time.  Statements  that are not statements
of historical  fact are  forward-looking  statements.  They are based on current
expectations.  In some cases,  you can identify  forward-looking  statements  by
terminology such as "may," "will,"  "should,"  "expect,"  "plan,"  "anticipate,"
"believe,"  "estimate,"  "predict,"  "intend,"  "potential" or "continue" or the
negative  of  these  terms  or  other  comparable  terminology.  Forward-looking
statements  involve risks and uncertainties  that could cause actual results and
the  timing of  events  to  differ  materially  from  those  anticipated  in our
forward-looking statements.  These risks and uncertainties include the impact of
competitive  products and pricing,  market  acceptance of new  products,  market
conditions, reliance on the efforts of distributors, enforcement of intellectual
property  rights and other factors set forth under the caption "Risk Factors" in
our Form 10-K for the year ended  December 31, 2000.  We assume no obligation to
update any of the forward-looking statements after the date of this report or to
conform these forward-looking statements to actual results.

OVERVIEW

     Cepheid is applying  proprietary  I-CORE  microfluidic and  microelectronic
technologies to the development of fast,  versatile systems that can perform all
the steps  required  to  analyze  DNA (or RNA) in complex  biological  samples -
sample  preparation,  amplification and detection - with results in less than 30
minutes on a single  instrument.  In 2000,  we launched our first  product,  the
Smart Cycler system, a system which performs  quantitative DNA amplification and
detection  in  a  single,  random  access  platform.  Our  initial  distribution
agreement  for the life  sciences  research  market  in the  United  States  was
finalized with Fisher Scientific Company L.L.C.  ("Fisher") in late 1999 and the
Smart Cycler was launched through Fisher in the United States in May 2000.

     During the third  quarter  of 2000,  we  selected  Takara  Shuzo Co.,  LTD.
("Takara") as our  distributor  to the life science  research  markets in Japan,
South Korea and Taiwan.  Takara initiated  product sales in its territory during
the fourth quarter. In December 2000 we selected Eurogentec SA ("Eurogentec") to
distribute  our Smart Cycler  system in Europe,  and Fisher as our  distribution
partner in Canada.  Eurogentec  initiated  product sales in the first quarter of
2001.  During the second  quarter of 2001,  we  selected  BioSyn Tech Sdn Bhd to
distribute our Smart Cycler system in Malaysia and Singapore. The product launch
occurred in July 2001.

     Our GeneXpert  system,  currently in development,  is designed to integrate
automated sample  preparation with our Smart Cycler  amplification and detection
technology in a disposable cartridge format. We are collaborating with strategic
partners to co-develop assays, or biological tests, and to provide marketing and
sales support across a broad range of markets.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 2001 COMPARED TO THREE MONTHS ENDED JUNE 30, 2000

REVENUES

     Total  revenues  increased  approximately  72% to  $2,042,000 in the second
quarter of 2001 from $1,189,000 in the second quarter of 2000. The components of
this increase were a $697,000 increase in product sales, coupled with a $277,000
increase in grant and  government-sponsored  research revenue and offset in part
by a $121,000 decrease in commercial  contract revenue.  The increase in product
sales was a result of the  launches  of our Smart  Cycler  product in the United
States,  Japan,  South Korea,  Taiwan,  Europe, and Canada beginning in May 2000
through the second quarter of 2001. As a result, we sold  approximately 65 Smart
Cyclers and approximately 200,000 tubes in the three months ended June 30, 2001.
The vast majority of these sales were through distributors.

COST OF PRODUCT SALES

     Cost of sales  increased 91% to  $1,303,000  in the second  quarter of 2001
from  $683,000  in the second  quarter  of 2000,  reflecting  the  corresponding
increase in product  sales.  Sales and cost of sales in 2000 reflect the initial
sales resulting from our product launch with Fisher in May 2000.
                                        8

RESEARCH AND DEVELOPMENT EXPENSES

     Research and development expenses decreased 11% to $3,607,000 in the second
quarter  of 2001 from  $4,060,000  in the  second  quarter  of 2000.  Research &
development efforts were shifted from primarily Smart Cycler development in 2000
to primarily GeneXpert development in 2001. These expenses include approximately
$379,000  and  $1,282,000  for the three  months  ending June 30, 2001 and 2000,
respectively,  of  non-cash  charges  related to the  amortization  of  deferred
stock-based  compensation,  a decrease of approximately  $903,000. The remaining
increase  in  expenses  of $450,000  was  primarily  attributable  to a $182,000
increase  in  salaries  and related  personnel  cost,  an increase of $86,000 in
temporary  help,  and an  increase of  $182,000  in outside  consulting  and lab
supplies and other development expenses.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling, general and administrative expenses increased 25% to $1,592,000 in
the second quarter of 2001 from $1,277,000 in the second quarter of 2000.  These
expenses include approximately $157,000 and $315,000 for the three months ending
June 30,  2001 and  2000,  respectively,  of  non-cash  charges  related  to the
amortization  of  deferred  stock-based  compensation.  The  remaining  $473,000
increase  was  primarily  attributable  to a $174,000  increase in salaries  and
related  personnel  costs,  an  increase of  $206,000  in  professional  service
expenses,  and a $93,000 increase in investor and public  relations,  insurance,
and other operating expenses.  Most of these increases relate to the addition of
a direct sales force,  customer support and technical  service people along with
other  infrastructure  to  support  the  launches  of the  Smart  Cycler  system
throughout the world, as well as the ongoing increased expenses  associated with
being a public company.

INTEREST INCOME, NET

     Net interest income increased 59% to $352,000 in the second quarter of 2001
from  $222,000 in the second  quarter of 2000.  This  $130,000  increase was due
primarily to increased  interest  income  generated  from the increased cash and
cash  equivalents  position  raised from our initial public offering on June 21,
2000.

NET LOSS PER COMMON SHARE

     Basic and diluted net loss per common share for the second  quarter of 2001
was $0.16,  compared with $0.60 for the same period in 2000. The pro forma basic
net loss per  common  share for the second  quarter of 2001 was $0.16,  compared
with  $0.24 for the same  period in 2000.  Pro forma net loss per share  amounts
assume  conversion  of preferred  stock to common at the time of their  original
issuance.

SIX MONTHS ENDED JUNE 30, 2001 COMPARED TO SIX MONTHS ENDED JUNE 30, 2000

REVENUES

     Total  revenues  increased  156 % to  $5,390,000 in the first six months of
2001 from $2,105,000 in the same period of 2000. The components of this increase
were a $2,906,000 increase in product sales, coupled with a $602,000 increase in
grant and  government-sponsored  research  revenue  and offset by a decrease  in
commercial  contract  revenue of $223,000.  The increase in product  sales was a
result of the launches of our Smart Cycler product in the United States,  Japan,
South Korea, Taiwan, Europe, and Canada beginning in May 2000 through the second
quarter of 2001.

COST OF PRODUCT SALES

     Cost of sales  increased  298% to $3,243,000 in the first half of 2001 from
$814,000 in the first half of 2000,  reflecting  the  corresponding  increase in
product  sales.  Sales  and cost of  sales in 2000  reflect  the  initial  sales
resulting from our product launch with Fisher in May 2000.

RESEARCH AND DEVELOPMENT EXPENSES

     Research and development  expenses  decreased 3% to $7,308,000 in the first
half of 2001 from $7,527,000 in the first half of 2000.  These expenses  include
approximately  $914,000 and  $1,856,000  for the six months ending June 30, 2001
and 2000,  respectively,  of non-cash  charges  related to the  amortization  of
deferred stock-based  compensation,  a decrease of approximately  $942,000.  The
remaining   increase  in  expenses  of  approximately   $723,000  was  primarily
attributable to a
                                        9

$312,000  increase  in  salaries  and  related  personnel  cost,  an increase of
$142,000 in additional  facility expenses,  an increase of $124,000 in temporary
help,  and an increase of $145,000  outside  consulting,  lab supplies and other
development expenses.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling, general and administrative expenses increased 49% to $2,997,000 in
the first six months of 2001 from  $2,007,000 in the same period of 2000.  These
expenses include  approximately  $389,000 and $521,000 for the six months ending
June 30,  2001 and  2000,  respectively,  of  non-cash  charges  related  to the
amortization  of deferred  stock-based  compensation.  The remaining  $1,122,000
increase  was  primarily  attributable  to a $377,000  increase in salaries  and
related  personnel  costs,  an  increase of  $309,000  in  professional  service
expenses and a $436,000  increase in investor and public  relations,  insurance,
and other operating expenses.  Most of these increases relate to the addition of
a direct sales force,  customer support and technical  service people along with
other  infrastructure  to  support  the  launches  of the  Smart  Cycler  system
throughout the world, as well as the ongoing increased expenses  associated with
being a public company.

INTEREST INCOME, NET

     Net interest  income  increased  127% to $865,000 in the first half of 2001
from  $381,000  in the  first  half of  2000.  This  $484,000  increase  was due
primarily to increased  interest  income  generated  from the increased cash and
cash equivalents raised from our initial public offering on June 21, 2000.

NET LOSS PER COMMON SHARE

     Basic and diluted net loss per common  share for the first half of 2001 was
$0.28,  compared with $4.23 for the same period in 2000. The pro forma basic net
loss per common share for the first half of 2001 was $0.28,  compared with $1.48
for the same  period  in 2000.  Pro  forma  net loss per  share  amounts  assume
conversion of preferred stock to common at the time of their original  issuance.
For the first half of 2000,  the actual and pro forma  basic net loss per common
share  includes  a  one-time  deemed  dividend  of $3.00 and  $1.05  per  share,
respectively, associated with a deemed dividend of $19.1 million relating to the
beneficial  conversion  feature  associated  with the January through March 2000
private placements of preferred stock.

LIQUIDITY AND CAPITAL RESOURCES

     We have financed our operations from inception  through proceeds  generated
from our initial  public  offering  of our common  stock on June 21,  2000,  and
through private sales of convertible  preferred stock,  contract  payments to us
under  government and commercial  research and development  agreements,  product
sales and equipment financing  arrangements.  Through June 30, 2001, we received
net proceeds of $65.2 million from issuances of common and convertible preferred
stock. In addition,  through June 30, 2001, we had financed equipment  purchases
and leasehold  improvements totaling  approximately  $3,883,000.  As of June 30,
2001, we had $2,542,000 in equipment  financing  obligations.  These obligations
are secured by the equipment financed, bear interest at a weighted average fixed
rate of 11.4% and are due in monthly  installments  through May 2005.  Under the
terms of the equipment  financing  agreement a balloon payment is due at the end
of the loan term. As of June 30, 2001, we had approximately  $191,000  available
under an equipment financing line of credit, which expires October 31, 2001.

     As of June 30, 2001, we had $32.8 million in cash and cash equivalents,  as
compared to $39.7  million as of December 31, 2000.  Net cash used for operating
activities  was $6.6 million for the six months  ended June 30,  2001,  and $5.4
million for the six months  ended June 30,  2000.  For the six months ended June
30,  2001,  this  consisted of a net loss for the period of  $7,293,000,  and an
increase in working capital of $1,181,000, which were offset in part by non-cash
charges of  $1,303,000  related to  stock-based  compensation,  and  $592,000 of
amortization and depreciation  expense.  For the six months ended June 30, 2000,
cash used for operating  activities  consisted of $7,862,000 in net loss, offset
by an increase  of $292,00 in working  capital,  as well as non-cash  charges of
$2,377,000 related to stock-based  compensation and $414,000 of amortization and
depreciation for the period.

     Capital  expenditures for property and equipment were $810,000 in the first
six months of 2001  compared to  $1,046,000  for the same period in 2000. In the
first half of 2001,  we  received  $282,000  from the sale of common  shares and
received proceeds from equipment financing of $631,000,  offset by repayments of
$472,000.  We  received  $46,442,000,  net of  costs  in cash  from  the sale of
preferred and common shares during the six month period ended June 30, 2000, and
used $241,000 to repay equipment financing obligations.

                                       10

     We expect to have negative cash flow from operations through at least 2003.
We expect to incur  increasing  research and  development  expenses,  as well as
expenses for additional personnel for production and commercialization  efforts.
Our future capital requirements depend on a number of factors,  including market
acceptance of our products, the resources we devote to developing and supporting
our products,  continued  progress of our research and  development of potential
products, the need to acquire licenses to new technology and the availability of
other  financing.  We believe  that our current  cash  balances,  together  with
revenue  to  be  derived  from  product  sales  and  research  and   development
collaborations,  will be sufficient to fund our  operations at least through the
year 2002. To the extent our capital  resources are  insufficient to meet future
capital  requirements,  we will  need  to  raise  additional  capital  or  incur
indebtedness to fund our  operations.  There can be no assurance that additional
debt or equity  financing will be available on acceptable  terms,  if at all. If
adequate funds are not available,  we may be required to delay, reduce the scope
of  or   eliminate   our   research  and   development   programs,   reduce  our
commercialization   efforts   or  obtain   funds   through   arrangements   with
collaborative  partners or others that may  require us to  relinquish  rights to
technologies   or  products  that  we  might   otherwise   seek  to  develop  or
commercialize.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     There have not been any  material  changes in our  exposure  to market risk
during the six months  ended June 30, 2001 which would  require an update to the
disclosures provided in our Annual Report on form 10-K for the fiscal year ended
December 31, 2000.

                                     PART II

ITEM 1. LEGAL PROCEEDINGS

     On April 12,  2001,  a complaint  was filed in the United  States  District
Court for the Western  District of  Pennsylvania  by Fisher  Scientific  Company
L.L.C.,  against  Cepheid and two of our employees.  The complaint  alleges that
defendant  Cepheid's hiring two former Fisher employees  violates the employees'
employment  agreements  with Fisher as well as Fisher's  distribution  agreement
with Cepheid, and asserts a variety of contract,  tort and trade secrets claims.
The complaint seeks declaratory relief and damages of an unspecified amount.

     There has been no discovery to date and no trial is  scheduled.  We believe
that we have  meritorious  defenses  to this  action  and if the  claims are not
withdrawn, intend to defend them vigorously.
