3.  REVENUE  RECOGNITION

     The Company recognizes revenue for database collaboration agreements evenly
over  the  term  of each agreement. Revenue is deferred for fees received before
earned.  Revenues  from  genomic  screening services and reagents are recognized
upon  completion  and shipment. Revenues from contract sequencing are recognized
upon  completion of milestones. Revenue from gene expression microarray services
includes:  technology  access  fees, which are generally recognized ratably over
the  access  term;  capacity  ramp  up  charges, which are recognized ratably as
capacity  is increased; and usage fees which are recognized at the completion of
key  stages  in the performance of the service, in proportion to costs incurred.
Generally,  software  revenue  is allocated between license fees and maintenance
fees,  in  accordance  with  SOP 97-2, with the license revenue being recognized
upon  installation,  and maintenance fees recognized evenly over the maintenance
term.

4.  NET  INCOME  (LOSS)  PER  SHARE

     Basic net income (loss) per share is computed by dividing net income (loss)
(numerator)  by  the  weighted  average  number  of  common  shares  outstanding
(denominator)  during  the  period  and  excludes  the  dilutive effect of stock
options.  Diluted  net  income  (loss)  per  share  gives effect to all dilutive
potential  common  shares  outstanding during a period. In computing diluted net
income  (loss)  per  share,  the  average  stock price for the period is used in
determining  the number of shares assumed to be purchased from exercise of stock
options.

Following  is  a  reconciliation of the numerators and denominators of the basic
and  diluted  net  income  (loss)  computations for the periods presented below.

at June 30, 1999, but were not included in the computation of diluted net income

effect  was  antidilutive.

5.  BUSINESS  COMBINATIONS

     In September 1998, the Company completed the acquisition of Hexagen Limited
("Hexagen"),  a  privately  held  single nucleotide polymorphism (SNP) discovery
company  based  in  Cambridge, England. The Company issued 976,130 shares of the
Company's common stock and $5.0 million in cash in exchange for all of Hexagen's
outstanding  capital  stock.  In  addition,  the Company assumed Hexagen's stock
options,  which if fully vested and exercised, would amount to 125,909 shares of
its common stock. The transaction was accounted for as a purchase with a portion
of the purchase price, $11.0 million, expensed in the third quarter of 1998 as a
charge  for  the  purchase of in-process research and development. The remaining
portion  of  the  purchase  price, approximately $17.6 million, was allocated to
goodwill  ($16.3  million),  developed  technology ($0.7 million), and Hexagen's
assembled  work  force ($0.6 million), which are being amortized over 8, 5 and 3
years,  respectively.

     The  Company  allocated Hexagen's purchase price based on the relative fair
value  of  the  net  tangible and intangible assets acquired. In performing this
allocation, the Company considered, among other factors, the technology research
and  development  projects  in  process  at  the  date of acquisition. Hexagen's
in-process  research and development program consisted of the development of its
fSSCP  technology  for  SNP discovery. At the date of the acquisition, Hexagen's
research  and  development  program  was  approximately  80% completed and total
continuing  research  and  development commitments to complete the projects were
expected  to be approximately $1.4 million, and were expected to be successfully
completed  by  mid-2000.  The  value  assigned  to  purchased in-process R&D was
determined  by  estimating  the  costs to develop Hexagen's purchased in-process
research  and  development  into  commercially  viable  products, estimating the
resulting net cash flows from the projects and discounting the net cash flows to
their  present value. The rates utilized to discount the net cash flows to their
present  value  were  based  on  Hexagen's  weighted  average cost of capital. A
discount  rate  of  24.0%  was  used  for  valuing  the  in-process research and
development and is intended to be commensurate with Hexagen's corporate maturity
and  the  uncertainties in the economic estimates described above. Additionally,
these  projects  will  require maintenance expenditures when and if they reach a
state  of  technological  and  commercial  feasibility.  Management believes the
Company  has positioned itself to complete the research and development program.
However,  there  is  risk  associated  with the completion of the project, which
include  the  inherent difficulties and uncertainties in completing each project
and  thereby achieving technological feasibility and risks related to the impact
of potential changes in future target markets and there is no assurance that the
project  will  meet  either  technological  or  commercial  success.  Failure to
complete the development of the fSSCP technology in its entirety, or in a timely
manner,  could  have  a  material  adverse  impact  on  the  Company's financial
condition  and  results  of  operations.

     The  estimates  used  by  the  Company  in  valuing in-process research and
development  were  based  upon assumptions the Company believes to be reasonable
but  which  are  inherently  uncertain  and  unpredictable.  Accordingly, actual
results  may  vary  from the projected results. The Company's assumptions may be
incomplete  or  inaccurate,  and  no  assurance  can be given that unanticipated
events and circumstances will not occur. To date, there have been no significant
changes to the Company's assumptions. Any such variance may result in a material
adverse  effect  on  the  financial  condition  and results of operations of the
Company. Associated risks include the inherent difficulties and uncertainties in
completing  each  project  and  thereby  achieving technological feasibility and
risks  related  to the impact of potential changes in future target markets. The
results  of operations of Hexagen have been included in the consolidated results
of  the  Company  from  the  date  of  acquisition  in  September  1998.

     The  table  below presents the pro forma results of operations and earnings
per  share for the combined results of Hexagen and the Company for the three and
six  months  ended June 30, 1998 assuming that the transactions was completed on
January  1,  1998.

     In  January  1998,  the  Company issued 2,340,237 shares of common stock in
exchange  for  all  of the capital stock of Synteni, Inc., a privately held gene
expression  microarray  company located in Fremont, California. Synteni provides
microarray  services  to  the  pharmaceutical,  biotechnology,  and agricultural
industries.  The  merger  has  been  accounted  for  as  a pooling-of-interests.

6.  JOINT  VENTURE

     In  September  1997,  the  Company  formed  a  joint venture, diaDexus, LLC
("diaDexus"),  with  SmithKline  Beecham  Corporation  ("SB") which will utilize
genomic and bioinformatic technologies in the discovery and commercialization of
molecular  diagnostics.  The  Company  holds  a  50  percent  equity interest in
diaDexus  and accounts for the investment under the equity method. In July 1999,
the  Company and SB each invested an additional $2.5 million in diaDexus through
convertible  notes  that mature in April  2000. The notes bear interest at 5.6%,
and  are  subordinate  to  all  other  claims. The notes, principal plus accrued
interest, will automatically convert into diaDexus Series C Preferred Stock upon
the  closing of the sale of Series C Preferred Stock of diaDexus that results in
aggregate proceeds to diaDexus of at least $10 million, including the $5 million
that  would  result  from  the  conversion of the loans from SB and the Company.

7.  SEGMENT  REPORTING

     The  Company  operates  primarily  in  one  reportable segment: the design,
development,  and  marketing of genomic information based tools, and follows the
requirements  of  SFAS  131,  Disclosures  about  Segments  of an Enterprise and
Related  Information.  For  the  three  and  six months ended June 30, 1999, the
Company  recorded  revenue  from  customers  throughout the United States and in
Canada, Austria, Belgium, France, Germany, Israel, Netherlands, Switzerland, and
the  United  Kingdom.  Export  revenues  were $9,797,000 and $20,580,000 for the
three  and  six  months  ended  June  30, 1999, respectively, and $7,546,000 and
$16,639,000  for  the  three  and  six months ended June 30, 1998, respectively.

8.  NEW  PRONOUNCEMENTS

     In  June 1998, the FASB issued Statement No. 133, Accounting for Derivative
Instruments  and  Hedging Activities. ("SFAS 133"). As modified by Statement No.
137,  Accounting for Derivative Instruments and Hedging Activities - Deferral of
the  Effective  Date  of FASB Statement NO. 133, this statement is effective for
fiscal  years  beginning after June 15, 2000. SFAS 133 established standards for
reporting derivative instruments and hedging activities. Application of SFAS 133
is  expected to have no impact on the consolidated financial position or results
of  operations  as  currently  reported.

9.  LITIGATION

     On  January 6, 1998, Affymetrix, Inc. ("Affymetrix") filed a lawsuit in the
United  States  District  Court  for  the  District  of  Delaware,  subsequently
transferred  to  the  United  States District Court for the Northern District of
California  in  November  1998,  alleging  infringement  of  U.S.  patent number
5,445,934  (the "'934 Patent") by both Synteni and Incyte. The complaint alleges
that  the  '934  Patent  has  been  infringed  by  the  making,  using, selling,
importing,  distributing  or offering to sell in the U.S. high density arrays by
Synteni  and  Incyte  and that such infringement was willful. Affymetrix seeks a
permanent  injunction  enjoining Synteni and Incyte from further infringement of
the  '934  Patent and, in addition, seeks damages, costs and attorney's fees and
interest.  Affymetrix further requests that any such damages be trebled based on
its  allegation  of  willful  infringement  by  Incyte  and  Synteni.

     In  September  1998,  Affymetrix  filed an additional lawsuit in the United
States  District Court for the District of Delaware, subsequently transferred to
the  United  States  District  Court  for the Northern District of California in
November  1998,  alleging  infringement of the U.S. patent number 5,800,992 (the
"'992  Patent")  and  U.S.  patent  number 5,744,305 (the "'305 Patent") by both
Synteni  and  Incyte.  The  complaint  alleges  that  the  '305  Patent has been
infringed  by the making, using, selling, importing, distributing or offering to
sell  in  the  United States high density arrays by Synteni and Incyte, that the
'992  Patent  has  been  infringed  by  the  use of Synteni's and Incyte's GEMTM
microarray  technology  to  conduct  gene  expression monitoring using two-color
labeling,  and  that such infringement was willful. Affymetrix seeks a permanent
injunction  enjoining  Synteni  and Incyte from further infringement of the '305
and  '992  Patents  and,  in  addition,  Affymetrix  had  sought  a  preliminary
injunction  enjoining  Incyte  and Synteni from using Synteni's and Incyte's GEM
microarray  technology  to  conduct  gene  expression monitoring using two-color
labeling as described in the '992 Patent. Affymetrix's request for a preliminary
injunction  was denied in April 1999 and the lawsuit is tentatively scheduled to
go  to  trial  in  July  2000.

     In  April  1999,  the  Board  of Patent Appeals and Interferences of United
States  Patent and Trademark Office (PTO) declared interferences between pending
patent  applications  licensed exclusively to Incyte and the Affymetrix '305 and
'992  Patents.  An  interference proceeding is invoked by the PTO when more than
one  patent applicant claims the same invention. The Board of Patent Appeals and
Interferences  evaluates all relevant facts, including those bearing on first to
invent, validity, enablement and scope of claims, and then makes a determination
as  to  who,  if  anyone,  is  entitled to the patent on the disputed invention.

     Incyte  and  Synteni  believe  they have meritorious defenses and intend to
defend  the suits vigorously. However, there can be no assurance that Incyte and
Synteni  will  be  successful  in  the defense of these suits. At this time, the
Company cannot reasonably estimate the possible range of any loss resulting from
these suits due to uncertainty regarding the ultimate outcome. Regardless of the
outcome,  this  litigation has resulted and is expected to continue to result in
substantial  expenses  and  diversion of the efforts of management and technical
personnel.  Further,  there  can  be  no  assurance that any license that may be
required as a result of this suit or the outcome thereof would be made available
on  commercially  acceptable  terms,  if  at  all.



PART  I:  FINANCIAL  INFORMATION
ITEM  2


                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


     This  Management's  Discussion  and  Analysis  of  Financial  Condition and
Results  of  Operations  as  of  June  30,  1999 and for the three and six month
periods  ended  June  30,  1999  and 1998 should be read in conjunction with the
unaudited  condensed  consolidated  financial  statements  and notes thereto set
forth in Item 1 of this report and the section entitled "Management's Discussion
and  Analysis of Financial Condition and Results of Operations" in the Company's
Annual  Report  on  Form  10-K  for  the  year  ended  December  31,  1998.

     When  used  in  this  discussion,  the  words  "expects,"  "anticipates,"
"estimates,"  and  similar  expressions are intended to identify forward-looking
statements.  Such  statements, which include statements as to expected net loss,
expected  expenditure  levels,  expected  cash  flows,  the  adequacy of capital
resources,  growth  in  operations and Year 2000 related actions, are subject to
risks  and  uncertainties  that  could cause actual results to differ materially
from those projected. These risks and uncertainties include, but are not limited
to, those risks discussed below, as well as the extent of utilization of genomic
information  by  the biotechnology, pharmaceutical, and agricultural industries;
risks  relating  to  the  development of new products and their use by potential
collaborators  of  the  Company;  the  impact  of  technological  advances  and
competition;  the  ability  of  the  Company  to  obtain  and  retain customers;
competition  from  other entities; early termination of a database collaboration
agreement  or  failure  to  renew  an  agreement upon expiration; the ability to
successfully  integrate the operations of recent business combinations; the cost
of  accessing  technologies  developed by other companies; uncertainty as to the
scope  of  coverage,  enforceability  or commercial protection from patents that
issue  on  gene  sequences  and  other  genetic information; developments in and
expenses  relating  to  litigation and interference proceedings; the results and
viability  of  joint  ventures and businesses in which the Company has purchased
equity;  the ability of the Company to implement in a timely manner the programs
and  actions  related  to  the  Year  2000  issue;  and the matters discussed in
"Factors  That  May Affect Results." These forward-looking statements speak only
as  of  the  date  hereof.  The  Company  expressly  disclaims any obligation or
undertaking  to release publicly any updates or revisions to any forward-looking
statements  contained herein to reflect any change in the Company's expectations
with  regard  thereto  or  any  change in events, conditions or circumstances on
which  any  such  statement  is  based.


OVERVIEW

     Incyte  Pharmaceuticals, Inc. ("Incyte" and, together with its wholly owned
subsidiaries,  the  "Company")  designs,  develops  and  markets  genomic
information-based  tools  including  database  products, genomic data management
software  tools,  microarray-based gene expression services and genomic reagents
and  related  services. The Company's genomic databases integrate bioinformatics
software  with  proprietary  and,  when  appropriate, publicly available genetic
information  to  create  information-based  tools  used  by  pharmaceutical  and
biotechnology  companies  in  drug  discovery  and  development.

     Revenues  recognized  by  the  Company  consist  primarily of non-exclusive
database  access  fees related to database agreements. Revenues also include the
sales of genomic screening products and services, fees for microarray-based gene
expression services, fees for contract sequencing services, and sales of genomic
data  management  software  tools. The Company's database agreements provide for
future  milestone  payments and royalties from the sale of products derived from
proprietary  information  obtained  through  the  databases.  There  can  be  no
assurance  that  any  database  subscriber  will  ever  generate  products  from
information  contained  within the databases and thus that the Company will ever
receive  milestone  payments or royalties. The Company's ability to maintain and
increase  revenues  will  be  dependent  upon  its  ability to obtain additional
database  subscribers,  retain  and  expand  its  relationships  with  existing
subscribers,  and  to  expand  its  customer  base  and  production capacity for
microarray  services.  The  loss  of  revenues  from  any  individual  database
agreement,  if  terminated  or  not renewed, could have an adverse impact on the
Company's  results  of  operations,  although  it  is  not anticipated to have a
material  adverse  impact  on  the  Company's  business  or financial condition.

     The  Company  is making a significant investment in its genomic sequencing,
bioinformatics,  mapping and SNP discovery programs in 1999, and as a result the
Company  has  reported  a  net  loss  for  the first half of 1999 and expects to
continue  to  incur losses through 1999. The Company is anticipating a return to
profitability  in  the  second  half of 2000. If the costs of these programs are
greater  than  anticipated,  or if these programs take longer to complete, or if
the  Company's business is affected by factors discussed under "Factors That May
Affect  Results"  the  Company  may  not  return  to  profitability  in  2000.

     In September 1998, the Company completed the acquisition of Hexagen Limited
("Hexagen"), a privately held SNP discovery company based in Cambridge, England.
The  Company  issued 976,130 shares of its common stock and $5.0 million in cash
in  exchange  for  all  of Hexagen's outstanding capital stock. In addition, the
Company  assumed  Hexagen's  stock options, which if fully vested and exercised,
would  amount  to  125,909  shares  of the Company's common stock. The intrinsic
value  of  the  stock options was included in the purchase price of Hexagen. The
transaction  was  accounted  for  as  a  purchase with a portion of the purchase
price,  estimated  to  be  approximately  $11.0  million,  expensed in the third
quarter  of  1998  as  a  charge  for  the  purchase  of in-process research and
development.  The  remainder of the purchase price, approximately $17.6 million,
was  allocated to goodwill ($16.3 million), developed technology ($0.7 million),
and  Hexagen's  assembled  work  force ($0.6 million), which are being amortized
over  8,  5 and 3 years, respectively. The Company will continue to evaluate its
intangible  assets  for  impairment  on  a  quarterly  basis.

The  Company allocated Hexagen's purchase price based on the relative fair value
of  the  net  tangible  and  intangible  assets  acquired.  In  performing  this
allocation, the Company considered, among other factors, the technology research
and  development  projects  in  process  at  the  date of acquisition. Hexagen's
in-process  research and development program consisted of the development of its
fSSCP  technology  for  SNP discovery. At the date of the acquisition, Hexagen's
research  and  development  program  was  approximately  80% completed and total
continuing  research  and  development commitments to complete the projects were
expected  to  be  approximately  $1.4  million. The projects were expected to be
successfully  completed  by mid-2000. The value assigned to purchased in-process
R&D  was  determined  by  estimating  the  costs  to develop Hexagen's purchased
in-process  research  and  development  into  commercially  viable  products,
estimating  the  resulting  net cash flows from the projects and discounting the
net  cash  flows  to their present value. The rates utilized to discount the net
cash  flows to their present value were based on Hexagen's weighted average cost
of  capital.  A  discount  rate  of  24.0%  was  used for valuing the in-process
research  and  development  and  is  intended  to be commensurate with Hexagen's
corporate  maturity  and  the  uncertainties in the economic estimates described
above. Additionally, this project will require maintenance expenditures when and
if  it  reaches  a state of technological and commercial feasibility. Management
believes  the  Company  has  positioned  itself  to  complete  the  research and
development  program.  However,  there is risk associated with the completion of
the  project,  which  includes  the  inherent  difficulties and uncertainties in
completing the project and thereby achieving technological feasibility and risks
related to the impact of potential changes in future target markets. There is no
assurance that the project will meet either technological or commercial success.
Failure  to complete the development of the fSSCP technology in its entirety, or
in  a  timely  manner,  could  have  a  material adverse impact on the Company's
financial  condition  and  results  of  operations.

     The  estimates  used  by  the  Company  in  valuing in-process research and
development  were  based  upon assumptions the Company believes to be reasonable
but  which  are inherently uncertain and unpredictable. To date, there have been
no  significant  changes to the Company's assumptions. The Company's assumptions
may  be  incomplete  or  inaccurate,  and  no  assurance  can  be  given  that
unanticipated  events  and  circumstances  will  not  occur. Accordingly, actual
results  may  vary from the projected results. Any such variance may result in a
material  adverse effect on the financial condition and results of operations of
the  Company.

     In  January  1998,  the  Company completed the acquisition of Synteni, Inc.
("Synteni"),  a  privately-held  microarray-based  gene  expression company. The
transaction  has  been  accounted  for  as  a  pooling  of  interests,  and  the
consolidated  financial statements discussed herein and all historical financial
information  have  been  restated  to  reflect  the  combined operations of both
companies. The Company's ability to generate revenues and operating profits from
microarray-based  gene  expression  services will be dependent on the ability of
the  Company  to obtain additional high volume customers for microarray services
and  to  expand  capacity  in  a  cost-effective  manner.  Prior  to the merger,
Synteni's  microarray  service  agreements  consisted  of  small volume pilot or
feasibility  agreements.

     In  September  1997,  the  Company  formed  a  joint venture, diaDexus, LLC
("diaDexus"),  with  SmithKline  Beecham  Corporation  ("SB") which will utilize
genomic  and  bioinformatics technologies in the discovery and commercialization
of  molecular  diagnostics.  The  Company  and  SB each hold a 50 percent equity
interest  in  diaDexus. The investment is accounted for under the equity method,
and  the  Company  records  its  share  of  diaDexus' earnings and losses in its
statement  of  operations.

     In  July  1999, the Company and SB each invested an additional $2.5 million
in  diaDexus  through convertible subordinated notes that mature in April, 2000.
The  notes  bear  interest  at 5.6% and are subordinate to all other claims. The
notes, principal plus accrued interest, will automatically convert into diaDexus
stock  upon diaDexus obtaining at least $10 million of funding, including the $5
million  from that would result from the conversion of the loans from SB and the
Company,  in  the  form  of  Series  C  Preferred  Stock.

     The  Company  has  made  and  intends  to continue to make strategic equity
investments  in,  and  acquisitions  of,  technologies  and  businesses that are
complementary  to  the  businesses  of the Company. As a result, the Company may
record  losses  or  expenses  related  to  the Company's proportionate ownership
interest  in  such  long-term  equity  investments,  record  charges  for  the
acquisition of in-process technologies, or record charges for the recognition of
the  impairment  in the value of the securities underlying such investments. The
market  prices  of  the securities of the companies in which the Company invests
are  highly  volatile  and  therefore  subject  to declines in market value. The
Company  will  continue  to  evaluate  its  long-term  equity  investments  for
impairment  on  a  quarterly  basis.

     In January 1998, the Company announced a relationship relating to the joint
development  of  proteomics  data and related software with Oxford GlycoSciences
plc  ("OGS").  As  part  of  this  relationship, the Company made a $5.0 million
initial  equity  investment  and  a  follow-on  investment  in  April  1998  of
approximately  $0.8  million  as  part of the OGS initial public offering of its
ordinary  shares. As part of the collaborative agreement, the Company has agreed
to  reimburse  OGS for up to $5.0 million in 1999 if revenues are not sufficient
to  offset  OGS'  expenses  for  services  rendered.

     In  an effort to broaden its business, the Company is investing in a number
of new areas, including  molecular diagnostics, genome sequencing, SNP discovery
and  proteomics.  Given  that  many  of  these  address  new markets, or involve
untested  technologies, it is not known if any of them will generate revenues or
if  the  revenues  will  be  sufficient  to  provide  an  adequate return on the
investment.  Depending  on  the  investment  required  and  the  timing  of such
investments,  expenses  or  losses  related to these investments could adversely
affect  operating  results.

     The  Company  has  incurred  and is likely to continue to incur substantial
expenses  in  its defense of the lawsuits filed in January and September 1998 by
Affymetrix,  Inc.  ("Affymetrix")  alleging  patent  infringement by Synteni and
Incyte.  Affymetrix  seeks  a  permanent injunction enjoining Incyte and Synteni
from further infringement of certain Affymetrix microarray patents. In addition,
Affymetrix  seeks  damages,  costs,  attorneys'  fees  and  interest. Affymetrix
further  requests  that any such damages be trebled on its allegation of willful
infringement  by  Incyte  and  Synteni.  Incyte  and  Synteni  believe they have
meritorious defenses and intend to defend these suits vigorously. However, there
can be no assurance that Incyte and Synteni will be successful in the defense of
these  suits.  At this time, the Company cannot reasonably estimate the possible
range  of  any  loss  related  to  these  suits due to uncertainty regarding the
ultimate outcome. Regardless of the outcome, this litigation has resulted and is
expected  to  continue  to  result  in substantial expenses and diversion of the
efforts  of  management  and  technical  personnel.  Any future litigation could
result  in  similar  expenses and diversion of efforts. Further, there can be no
assurance  that  any  license that may be required as a result of these suits or
the outcome thereof would be made available on commercially acceptable terms, if
at  all.

RESULTS  OF  OPERATIONS

     Net  loss and diluted net loss per share were $7.4 million and $9.3 million
and  $0.26 and $0.33 per share for the three and six months ended June 30, 1999,
respectively, as compared to net income and diluted net income per share of $5.2
million  and  $8.8  million  and $0.18 and $0.30 per share in the same periods a
year  ago,  respectively.

     Revenues  for  the  three  and  six months ended June 30, 1999 increased to
$37.9  million  and  $75.5  million, respectively, compared to $33.1 million and
$63.5 million for the corresponding periods in 1998. Revenues resulted primarily
from  database  access fees and, to a much lesser extent, from genomic screening
products  and  services,  microarray-based  gene  expression  services, contract
sequencing,  and  genomic  data  management  software tools and maintenance. The
increase in revenues was primarily attributed to expanded collaborative database
agreements,  and to a lesser extent, to increased revenues from microarray-based
gene  expression  services.

     Total  costs  and expenses for the three and six months ended June 30, 1999
increased  to  $45.6  million and $85.2 million, respectively, compared to $28.8
million and $56.3 million for the corresponding periods in 1998. Total costs and
expenses  for  the  six  month  period  ended  June  30,  1998  included  an
acquisition-related  charge of $1.2 million for the acquisition of Synteni, Inc.
The charge consisted primarily of accounting, legal and investment banking fees.
Total  costs and expenses are expected to increase in the foreseeable future due
to  significant  expansion  of  microarray  production  capacity,  the continued
investment  in  new  product  development  and bioinformatics, and the growth in
marketing,  sales  and  customer  services.

     Research  and  development expenses for the three and six months ended June
30, 1999 increased to $36.1 million and $67.4 million, respectively, compared to
$23.1  million  and  $44.8  million  for  the corresponding periods in 1998. The
increase  in  research and development expenses resulted primarily from the ramp
up  in  expenses  related to the Company's investment in its genomic sequencing,
bioinformatics,  gene  mapping  and  SNP  discovery  programs,  increase  in its
microarray  production,  and continued investment in the growth of the Company's
intellectual  property  portfolio.  The Company expects research and development
spending  to  continue  to  increase  as  the  Company  continues  to pursue the
development  of new database products and services, invests in new technologies,
broadens  its  microarray production operations and invests in the protection of
its  intellectual  property.

     Selling,  general  and administrative expenses for the three and six months
ended  June  30, 1999 increased to $9.5 million and $17.9 million, respectively,
compared  to  $5.7  million  and  $10.3 million for the corresponding periods in
1998.  The  increase  in  selling,  general and administrative expenses resulted
primarily  from  the  expansion  of the Company's United Kingdom operations, the
growth  in sales and marketing activities and increased personnel to support the
growing complexity of the Company's operations. The Company's operations for the
three  and  six  months ended June 30, 1999 were also impacted by legal expenses
from  the patent infringement lawsuits filed by Affymetrix of approximately $2.0
million  and  $4.1  million,  respectively.  The  Company  expects that selling,
general  and  administrative  expenses  will  increase  throughout  1999  due to
continued  growth  in  marketing,  sales  and  customer  support  functions  and
increases  in  personnel  to  support the Company's growing complexity. Selling,
general  and administrative expenses could fluctuate from quarter to quarter due
to  the  timing  of  legal  expenses  related  to  the  Affymetrix  lawsuits.

     Interest  and other income, net for the three and six months ended June 30,
1999 decreased to $1.6 million and $3.0 million, respectively, from $1.8 million
and  $3.7  million  for  the  corresponding  periods  in  1998.  The decrease is
primarily  due  to  the  lower  cash,  cash  equivalent, and marketable security
balances  in  1999  as  compared  to  1998.

     Losses  from joint venture were $1.2 million and $2.6 million for the three
and  six months ended June 30, 1999, respectively, and zero and $0.6 million for
the  three and six months ended June 30, 1998, respectively. The loss represents
the Company's equity share of diaDexus' net losses from operations. In the three
months  ended  June  30,  1998,  the Company's share in diaDexus' net losses was
offset  by the amortization of the excess of the Company's share of diaDexus net
assets over its basis. diaDexus is expected to incur operating losses through at
least  2000.

     Due  to  the  Company's  expected  net  loss in 1999, the Company expects a
minimal  effective  annual income tax rate. The effective annual income tax rate
for  1998  was  14%,  which  represented  the  provision  of  federal  and state
alternative  minimum taxes after utilization of net operating loss carryforwards
and  research  and  development  credits.

LIQUIDITY  AND  CAPITAL  RESOURCES

     As  of  June  30,  1999,  the  Company  had  $106.1  million  in cash, cash
equivalents and marketable securities, compared to $111.2 million as of December
31,  1998.  The  Company  has  classified  all  of  its marketable securities as
short-term,  as  the  Company  may  choose not to hold its marketable securities
until  maturity  in  order  to  take  advantage  of favorable market conditions.
Available  cash is invested in accordance with the Company's investment policy's
primary  objectives  of  liquidity,  safety  of  principal  and  diversity  of
investments.

     Net  cash  provided  by  operating activities was $13.7 million for the six
months  ended  June  30,  1999,  as compared to $33.1 million for the six months
ended  June  30, 1998. The decrease in net cash provided by operating activities
resulted  primarily  from the change to a net loss for the six months ended June
30,  1999  from  net  income  in the corresponding period in 1998 as well as the
lower  increase  in  deferred  revenues  in 1999 as compared to 1998, which were
partially  offset  by higher non cash charges from depreciation and amortization
and  losses  in joint venture. Net cash generated by operating activities may in
the  future fluctuate significantly from quarter to quarter due to the timing of
large prepayments by database collaborators. Although the Company is expected to
be cash flow positive from operations in 1999, due to the significant investment
in  the  Company's genomic sequencing, bioinformatics, mapping and SNP discovery
programs,  the  Company  expects  a continued significant decrease in cash flows
from  operations  in  the  remainder  of  1999  as  compared  to  1998.

     The  Company's  investing  activities,  other  than  purchases,  sales  and
maturities  of  marketable  securities,  have  mainly  consisted  of  capital
expenditures  and long-term investments. Capital expenditures for the six months
ended  June  30,  1999 increased to $20.0 million from $15.3 million for the six
months  ended  June  30,  1998.  In  1999,  the  Company  has  made no long-term
investments  in  companies  with  which the Company has research and development
alliances  as  compared  to $6.9 million for the six months ended June 30, 1998.
Net  cash used by investing activities may in the future fluctuate significantly
from  quarter  to  quarter  due  to  the timing of strategic equity investments,
capital  purchases  and  maturity/sales  and purchases of marketable securities.

     Net  cash  provided  by  financing  activities was $1.1 million for the six
months  ended June 30, 1999 as compared to $2.8 million for the six months ended
June  30,  1998.  The  decrease  was  primarily due to lower proceeds from stock
option  exercises  in  1999.

     Based  upon  its  current  plans,  the  Company  believes that its existing
resources  and anticipated cash flow from operations will be adequate to satisfy
its  capital needs at least through the next twelve months. However, the Company
may  be  unable  to  obtain  additional  collaborators  or  retain  existing
collaborators  for  its databases, and its products and services may not produce
revenues  which,  together  with  the  Company's  cash,  cash  equivalents,  and
marketable  securities,  would  be  adequate  to  fund  the  Company's  cash
requirements.  The  Company's  cash  requirements  depend  on  numerous factors,
including the ability of the Company to attract and retain collaborators for its
databases  and  other  products  and services; the cost required to complete the
genomic sequencing and human genome mapping programs; expenditures in connection
with  alliances,  license  agreements  and  acquisitions  of  and investments in
complementary  technologies  and  businesses; competing technological and market
developments;  the  cost  of filing, prosecuting, defending and enforcing patent
claims  and  other  intellectual  property  rights;  the  purchase of additional
capital equipment, including capital equipment necessary to ensure the Company's
sequencing  and  microarray  operations remain competitive; capital expenditures
required  to  expand  the  Company's  facilities;  and costs associated with the
integration  of new operations assumed through mergers and acquisitions. Changes
in  the  Company's research and development plans or other changes affecting the
Company's  operating  expenses may result in changes in the timing and amount of
expenditures  of  the  Company's  capital  resources.

     The  Company  expects  to  continue to fund future operations with revenues
from database products and services and with its current cash, cash equivalents,
and  marketable  securities.  Additional  funding,  if  necessary,  may  not  be
available  on  favorable  terms,  if at all. If adequate funds are not available
through  the public markets and/or other sources, the Company may be required to
curtail  operations  significantly  or  to  obtain  funds  by  entering  into
collaborative  arrangements that may require the Company to relinquish rights to
certain  of its technologies, product candidates, products or potential markets.

EURO  CONVERSION

     A  single  currency  called the euro was introduced in Europe on January 1,
1999.  Eleven  of  the  fifteen member countries of the European Union agreed to
adopt  the  euro  as  their common legal currency on that date. Fixed conversion
rates  between  these  participating countries' existing currencies (the "legacy
currencies")  and  the  euro  were  established  as  of  that  date.  The legacy
currencies  are  scheduled  to  remain legal tender as denominations of the euro
until  at  least  January  1, 2002, but not later than July 1, 2002. During this
transition  period,  parties  may settle transactions using either the euro or a
participating  country's  legal  currency.  The  Company  does  not  expect this
conversion  to  have  a  material impact on its results of operations, financial
position  or  cash  flows.

YEAR  2000

     As  a  result  of  computer programs being written using two digits, rather
than  four,  to  represent year dates, the performance of the Company's computer
systems  and those of its suppliers and customers in the Year 2000 is uncertain.
Any  computer  programs  that  have time-sensitive software may recognize a date
using  "00"  as  the year 1900 rather than the year 2000. This could result in a
system  failure or miscalculations causing disruptions of operations, including,
among  other  things,  a  temporary  inability  to  process  transactions,  send
invoices,  or  engage  in  other  normal  business  activities.

     The  Company is in the process of evaluating the Year 2000 readiness of the
software  products  sold by the Company ("Products"), the information technology
systems  used  in its operations ("IT Systems"), and its non-IT Systems, such as
building  security,  voice  mail, and other systems. The project consists of the
following  phases:  (i)  identification  of all Products, IT Systems, and non-IT
Systems;  (ii) assessment of repair or replacement requirements; (iii) repair or
replacement;  (iv) testing; (v) implementation; and (vi) creation of contingency
plans  in  the  event  of  Year  2000  failures.

     The supplier of the Company's current financial and accounting software has
informed  the  Company  that  such  software is Year 2000 compliant. The Company
relies,  both domestically and internationally, upon various vendors, government
agencies,  utility  companies,  telecommunications  service  companies, delivery
service  companies, and other service providers who are outside of the Company's
control.  There  is  no  assurance that such parties will not suffer a Year 2000
business disruption, which could have a material adverse effect on the Company's
financial  condition  and  results  of  operations.

     The  Company  relies  for  its successful operation upon goods and services
purchased  from certain vendors. If these vendors fail to adequately address the
Year  2000  such  that  their  delivery  of goods and services to the Company is
materially  impaired,  it  could have a material adverse impact on the Company's
operations and financial results. The Company is in the process of surveying its
principal  vendors  to  assess the effect the Year 2000 issue will have on their
ability to supply their goods and services without material interruption, and at
this  time  the  Company cannot determine or predict the outcome of this effort.
Contingency  plans  will  be  developed and executed with respect to vendors who
will  not  be Year 2000 ready in a timely manner where such lack of readiness is
expected to have a material adverse impact on the Company's operations. However,
because  the  Company  cannot be certain that its vendors will be able to supply
material  goods  and  services  without  material  interruption, and because the
Company  cannot  be  certain  that  execution  of  its contingency plans will be
capable  of implementation or result in a continuous and adequate supply of such
goods  and  services,  the Company can give no assurance that these matters will
not  have  a  material  adverse  effect  on  the  Company's  future consolidated
financial  position,  results  of  operations,  or  cash  flows.

     If  the  Company's customers fail to achieve an adequate state of Year 2000
readiness  in  their  own  operations,  or  if their Year 2000 readiness efforts
consume  significant resources, their ability to purchase the Company's products
may  be  impaired. This could adversely affect demand for the Company's products
and,  therefore,  the  Company's future revenues. The Company plans to develop a
contingency  plan  for  Year 2000 noncompliant customers and at this time cannot
determine  the  impact  it  will  have,  if  any.

     In  the  second  quarter  of 1999, the Company completed its testing of all
current  versions of its software products, which disclosed nothing that results
in  Year  2000  non  compliance. Even so, whether a complete system or device in
which  a  Product  is embedded will operate correctly for an end-user depends in
large part on the Year 2000 compliance of the system's other components, most of
which  are  supplied by parties other than the Company. The Company is currently
evaluating  systems and software used internally at all locations of the Company
(including those from third-party vendors) for Year 2000 compliance. The initial
assessment  as  been  completed,  and  all  testing  and  remediation  for
mission-critical  systems  is  expected  to be completed by the end of the third
quarter  of  1999.

     To date, the Company has had expenditures of approximately $0.4 million for
external  vendors  for  assistance  with its Year 2000 assessment of IT internal
systems and for certification of its database and software products. In addition
the  Company has incurred minimal opportunity cost of time spent by employees of
the  Company evaluating its financial and accounting software, its products, and
general  Year 2000 compliance matters. Absent a significant Year 2000 compliance
deficiency,  management  currently  estimates that total costs for its Year 2000
compliance  programs  will  be between $1.0 million and $1.5 million, which will
total  approximately  10%  of  the total 1999 IT budget and is being expensed as
incurred.  The  Company  has  not deferred any IT projects due to its efforts to
ensure  Year  2000  compliance. The Company believes that available cash will be
sufficient  to  cover  the  projected  costs  associated  with these activities.

     The  Company  intends  to  develop and implement, if necessary, appropriate
contingency  plans  to  mitigate  to the extent possible the effects of any Year
2000  noncompliance, and expects to have such plans completed in the second half
of  1999.  As  part  of  the development of a contingency plan, the Company will
evaluate  its  worst  case  scenario  in  the  event of Year 2000 noncompliance.
Although  the full consequences are unknown, the failure of either the Company's
critical  systems or those of its material third party suppliers to be Year 2000
compliant  would  result  in  the  interruption of the Company's business, which
could  have  a  material  adverse  effect  on  the Company's business, financial
condition  and  results  of  operations.

FACTORS  THAT  MAY  AFFECT  RESULTS

     The  risks  and  uncertainties described below are not the only ones facing
our  company.  Additional  risks  and uncertainties not presently known to us or
that  we  currently  deem  immaterial  may  also impair our business operations.

     If  any  of  the  following  risks  actually occur, our business, financial
condition  and results of operations could be materially and adversely affected.

WE HAVE HAD ONLY LIMITED PERIODS OF PROFITABILITY, AND WE EXPECT TO INCUR LOSSES
IN  THE  FUTURE  AND  MAY  NOT  RETURN  TO  PROFITABILITY

     We  had net losses from inception in 1991 through 1996, reported net income
in  1997  and 1998, and as anticipated we were unprofitable in the first half of
1999. Because of those losses, we had an accumulated deficit of $37.7 million as
of  June 30, 1999. Because we intend to make a significant investment in genomic
sequencing,  mapping  and SNP discovery over the next 12 to 18 months, we expect
to  report  a  net  loss for 1999 and possibly 2000. We may report net losses in
future  periods  as  well.  We  expect  that  our  expenditures will continue to
increase,  due in part to our continued investment in new product and technology
development,  including  the  ramp-up of our genomic sequencing, bioinformatics,
mapping  and  SNP-discovery  programs,  obligations  under  existing  and future
research  and development alliances, and our increasing investment in marketing,
sales and customer service. Our profitability depends on our ability to increase
our  revenues:

     TO  GENERATE  SIGNIFICANT  REVENUES,  WE  MUST  OBTAIN  ADDITIONAL DATABASE
COLLABORATORS  AND  RETAIN  EXISTING  COLLABORATORS.   While  we had 22 database
agreements  as  of  June 30, 1999, we may be unable to enter into any additional
agreements. Although all agreements that have expired to date have been renewed,
we  cannot assure you that any other agreements will be renewed upon expiration.
Our  database  revenues  are  also  affected  by  the  extent  to which existing
collaborators  expand  their  agreements  with  us  to  include our new database
products  and  to  the  extent  that existing collaborators reduce the number of
products  or  services for which they subscribe. Some of our database agreements
require  us  to  meet  performance  obligations.  A  database  collaborator  can
terminate  its  agreement  before the end of its scheduled term if we breach the
agreement  and  fail  to  cure  the  breach  within  a  specified  period.

     OUR  REVENUES  AND  PROFITABILITY WILL ALSO DEPEND ON OUR ABILITY TO EXPAND
OUR  CUSTOMER BASE FOR MICROARRAY SERVICES. We acquired Synteni, Inc. in January
1998 primarily for this purpose. Synteni's contribution to our operating results
will  depend  on  whether  we  can  obtain  high-volume customers for microarray
services, whether we can increase our microarray production capacity in a timely
manner  and  with  consistent volumes and quality, and the costs associated with
increasing  our  microarray production capacity. Before we acquired Synteni, its
microarray  service  agreements  consisted  of small volume pilot or feasibility
agreements.

     WE  DO  NOT  EXPECT MILESTONE OR ROYALTY PAYMENTS TO CONTRIBUTE TO REVENUES
FOR  A  SUBSTANTIAL  PERIOD  OF  TIME.  Part  of  our  strategy is to license to
database  collaborators  our know how and patent rights associated with the gene
sequences  and  related information in our proprietary databases, for use in the
discovery  and  development  of  potential  pharmaceutical,  diagnostic or other
products.  Any  potential  product  that  is  the subject of such a license will
require  several  years  of further development, clinical testing and regulatory
approval  before commercialization. Accordingly, we do not expect to receive any
milestone  or  royalty  payments  from  any  of these licenses for a substantial
period  of  time,  if  at  all.

OUR  OPERATING  RESULTS  MAY  FLUCTUATE  SIGNIFICANTLY

     Our  operating  results  are  unpredictable and may fluctuate significantly
from  period  to  period  due  to  a  variety  of  factors,  including:

- -     changes  in  the  demand  for  our  products  and  services;

- -     the  introduction  of  competitive  databases  or  services;

- -     the  pricing  of  access  to  our  databases;

- -     the  nature, pricing and timing of other products and services provided to
our  collaborators;

- -     changes  in  the research and development budgets of our collaborators and
potential  collaborators;

- -     depreciation  expense  from  capital  expenditures;

- -     acquisition,  licensing  and  other  costs related to the expansion of our
operations,  including  operating  losses of acquired businesses such as Synteni
and  Hexagen;

- -     losses  and  expenses  related  to  our  investments in joint ventures and
businesses,  including  our  proportionate  share  of  operating  losses  of our
diaDexus,  LLC,  joint  venture  with  SmithKline  Beecham  Corporation;

- -     payments  of milestones, license fees or research payments under the terms
of  our  increasing  number  of  external  alliances;  and

- -     expenses  related to, and the results of, litigation and other proceedings
relating  to  intellectual  property  rights  (including  the  lawsuits filed by
Affymetrix,  Inc.  described  below).

     In  particular,  revenues  from  our  database  business  are unpredictable
because:

- -     the  timing  of  our  database  installations  is  determined  by  our
collaborators,

- -     the  sales  cycle  for  our  database  products  is  lengthy,  and

- -     the  time  required  to  complete  custom  orders  can vary significantly.

     We  expect our microarray services to represent an increasing amount of our
revenues.  Revenues  from  these  sources  depend  on  volume  of  usage  by our
collaborators,  and can therefore fluctuate significantly. Also, revenues can be
affected by developments in the Affymetrix litigation, which may cause potential
customers  to  postpone or change their decision to use our microarray services.

     We  are  investing in a number of new areas to try to broaden our business.
These  areas  include  genomic  sequencing and mapping, SNP discovery, molecular
diagnostics,  and  proteomics,  or  the large scale, high-throughput analysis of
protein  expression.  Because  many  of  these  address  new  markets or involve
untested technologies, they may not generate any revenues or provide an adequate
return  on  our investment. In these cases, we may have to recognize expenses or
losses.

     We  have significant fixed expenses, due in part to our need to continue to
invest  in  product  development  and  extensive  support  for  our  database
collaborators.  We  may  be  unable  to adjust our expenditures if revenues in a
particular  period  fail  to meet our expectations, which would adversely affect
our  operating  results  for  that period. Forecasting operating and integration
expenses for acquired businesses may be particularly difficult, especially where
the  acquired  business  focuses on technologies that do not have an established
market.

     We  believe that period-to-period comparisons of our financial results will
not  necessarily  be  meaningful. You should not rely on these comparisons as an
indication  of  our  future  performance. If our operating results in any future
period  fall  below  the  expectations of securities analysts and investors, our
stock  price  will  likely  fall,  possibly  by  a  significant  amount.

WE  EXPERIENCE  INTENSE  COMPETITION  AND  RAPID  TECHNOLOGICAL  CHANGE

     GENOMIC  BUSINESSES  ARE INTENSELY COMPETITIVE  The human genome contains a
finite  number  of  genes.  Our  competitors  may seek to identify, sequence and
determine  the  biological  function  of  numerous  genes  in  order to obtain a
proprietary  position  with  respect  to new genes. A number of companies, other
institutions  and  government-financed  entities are engaged in gene sequencing,
gene  discovery,  gene  expression  analysis,  positional  cloning, the study of
genetic  variation,  and  other  genomic  service  businesses.  Many  of  these
companies,  institutions and entities have greater financial and human resources
than  we  do.

     Some  of our competitors have developed databases containing gene sequence,
gene  expression,  genetic  variation  or  other  genomic  information  and  are
marketing  or  plan to market their data to pharmaceutical companies. Additional
competitors  may  attempt  to establish databases containing this information in
the  future.  We  expect  that  competition  in  our  industry  will continue to
intensify. Several large pharmaceutical companies have announced their intent to
form  a  consortium to create a SNPs database and to make all of the information
publicly  available.  The  formation  of  this sort of consortium could delay or
reduce  the  potential  revenues  related  to  our  SNP-related  business.

     PATENT  POSITIONS  OR  PUBLIC  DISCLOSURES  MAY  REDUCE  THE  VALUE  OF OUR
DATABASES.  Competitors may discover and establish patent positions with respect
to  gene  sequences  in our databases. Further, certain entities engaged in gene
sequencing have made the results of their sequencing efforts publicly available.
The  Celera Genomics Group of PE Corporation has announced plans to sequence the
entire human genome by the end of 2001 and to make the basic human sequence data
publicly  available.  The Human Genome Project, which is coordinated by the U.S.
Department of Energy and the National Institutes of Health, has announced that a
consortium  of  laboratories associated with the Project predicts that they will
produce  at  least  90  percent of the human genome sequence in a "working draft
form"  by  the  spring  of  2000  and  that  they intend to make the information
publicly  available.  The  public  availability  of  gene sequences or resulting
patent  positions covering substantial portions of the human genome or microbial
or  plant  genomes  could  reduce  the  potential  value of our databases to our
collaborators.  It  could  also impair our ability to realize royalties or other
revenue  from  any  commercialized  products  based on this genetic information.

     COMPETITORS  MAY DEVELOP SUPERIOR TECHNOLOGY.  The gene sequencing machines
used  in our computer-aided sequencing operations are commercially available and
are  being used by at least one competitor. In addition, some of our competitors
and  potential  competitors  are  developing proprietary sequencing technologies
that  may  be  more advanced than ours. PE Corporation has announced that it has
begun  commercial  shipments  of  a new gel-based sequencing machine, and that a
large number of these machines will be provided to Celera Genomics Group. We may
be  unable  to  obtain  access  to  these  machines  on  acceptable  terms.

     In  addition,  a  number  of companies are pursuing alternative methods for
generating gene expression information, including microarray technologies. These
advanced  sequencing  or  gene  expression  technologies may not be commercially
available for us to purchase or license on reasonable terms, if at all. At least
one  other  company  currently  offers  microarray-based  services that might be
competitive  with  ours.

     Our  SNP  discovery platform represents a modification of a process that is
in  the  public domain. We are seeking patent protection for these improvements,
but  have  not  yet  received any patents. Other companies could make similar or
superior  improvements to this process without infringing our rights, and we may
not  have  access  to those improvements. The discovery of SNPs is a competitive
area.  Other  companies  may develop or obtain access to different SNP discovery
platforms,  to  which  we  may  not  have  access,  that may make our technology
obsolete.

     We  also face competition from providers of software. A number of companies
have  announced  their  intent  to  develop  and  market  software  to  assist
pharmaceutical  companies  and  academic  researchers  in managing and analyzing
their  own genomic data and publicly available data. Some of these entities have
access  to  significantly  greater  resources than we do, and their products may
achieve  greater  market  acceptance  than  ours.

     WE  MUST  CONTINUE TO INVEST IN NEW TECHNOLOGIES.  The genomics industry is
characterized  by  extensive  research efforts, resulting in rapid technological
progress.  To  remain  competitive,  we  must  continue to expand our databases,
improve  our  software,  and  invest  in  new technologies. New developments are
expected  to  continue,  and  discoveries  by others may render our services and
potential  products  noncompetitive.

WE  ARE  INVOLVED  IN  PATENT  LITIGATION

     In  January  1998,  Affymetrix  filed  a  lawsuit in federal court alleging
infringement  of  U.S.  patent  number 5,445,934 by both Synteni and Incyte. The
complaint  alleges  that  the  '934  patent  has been infringed by Synteni's and
Incyte's  making,  using,  selling,  importing, distributing or offering to sell
high density arrays in the United States and that this infringement was willful.
Affymetrix  seeks  a  permanent  injunction  enjoining  Synteni  and Incyte from
further  infringement  of  the  '934 patent and seeks damages, costs, attorneys'
fees  and  interest.  Affymetrix also requests triple damages based on allegedly
willful  infringement.

     In  September  1998,  Affymetrix  filed  an  additional  lawsuit  alleging
infringement  of  U.S.  patent  numbers  5,744,305  and 5,800,992 by Synteni and
Incyte.  The  complaint  alleges  that  the  '305  patent  has been infringed by
Synteni's  and  Incyte's  making,  using,  selling,  importing,  distributing or
offering  to sell high density arrays in the United States. It also alleges that
the  '992  patent  has  been  infringed by the use of Synteni's and Incyte's GEM
microarray  technology  to  conduct  gene  expression monitoring using two-color
labeling  and  that  this  infringement  was  willful.  Affymetrix  had sought a
preliminary  injunction  enjoining  Synteni and Incyte from using GEM microarray
technology  to  conduct this kind of gene expression monitoring, and a permanent
injunction  enjoining  Synteni  and  Incyte from further infringing the '305 and
'992  patents.

     The  lawsuits  were initially filed in the United States District Court for
the District of Delaware. In November 1998, the court granted Incyte's motion to
transfer the suits to the United States District Court for the Northern District
of  California.  Affymetrix's request for a preliminary injunction was denied in
April 1999 and the lawsuit is tentatively scheduled to go to trial in July 2000.

     In  April  1999,  the  Board  of Patent Appeals and Interferences of United
States Patent and Trademark Office declared interferences between pending patent
applications  licensed  exclusively  to  us  and  the  Affymetrix  '305 and '992
patents.  An  interference  proceeding  is  invoked  by the Patent and Trademark
Office  when more than one patent applicant claims the same invention. The Board
of  Patent  Appeals  and  Interferences  evaluates all relevant facts, including
those  bearing on first to invent, validity, enablement and scope of claims, and
then  makes  a  determination as to who, if anyone, is entitled to the patent on
the  disputed  invention.  At  this  time, we can not predict the outcome of the
interference  proceeding.

     We  believe  we  have meritorious defenses and intend to defend these suits
vigorously.  However,  our  defense may be unsuccessful. At this time, we cannot
reasonably  estimate  the  possible range of any loss resulting from these suits
due  to  uncertainty  about  the  ultimate  outcome. We have spent and expect to
continue  to  spend  a  significant  amount of money and management time on this
litigation.  Also,  if  we are required to license any technology as a result of
these  suits,  we  do  not know whether we will be able to do so on commercially
acceptable  terms,  if  at  all.

WE  ARE  SPENDING  A LOT OF MONEY ON NEW AND UNCERTAIN BUSINESSES AND DEMAND FOR
OUR  PRODUCTS  AND  SERVICES  MAY  BE  INSUFFICIENT  TO  COVER  OUR  COSTS

     There  is  no  precedent  for  our microarray-based gene expression service
business  or  the use of SNP-based genetic variation information. The usefulness
of  the information generated by these businesses is unproven. Our collaborators
and potential collaborators may determine that our databases, software tools and
microarray-related  services are not useful or cost-effective. Due to the nature
and  price  of  the  products  and  services  we offer, only a limited number of
companies  are  potential  collaborators for our products and services. If we do
not  develop these new products and services in time to meet market demand or if
there is insufficient demand for these products and services, we may not be able
to  cover  our  costs  of  developing  these  products  and  services  or earn a
sufficient  return  on  our  investment.

     Additional  factors  that  may  affect demand for our products and services
include:

- -     the  extent  to  which  pharmaceutical and biotechnology companies conduct
these  activities  in-house  or  through  industry  consortia;

- -     the  emergence  of  competitors  offering  similar services at competitive
prices;

- -     the  extent to which the information in our databases is made public or is
covered  by  others'  patents;

- -     our  ability  to establish and enforce proprietary rights to our products;

- -     regulatory  developments  or changes in public perceptions relating to the
use  of  genetic information and the diagnosis and treatment of disease based on
genetic  information;  and

- -     technological  innovations  that  are  more advanced than the technologies
that  we  have  developed  or  that  are  available  to  us.

Many  of  these  factors  are  beyond  our  control.



OUR  NEW  PROGRAMS RELATING TO THE ROLE OF GENETIC VARIATION IN DISEASE AND DRUG
RESPONSE  ARE  RISKY

     We recently began to focus part of our business on developing databases and
other  products  and  services  to  assist pharmaceutical companies in a new and
unproven  area:  the  identification  and  correlation  of  genetic variation to
disease  and  drug  response.  Hexagen,  which will be an important part of this
business,  was  founded  in  1996 and has generated no revenues to date. We will
incur  significant  costs  over the next several years in expanding our research
and  development  in  this area. These activities may never generate significant
revenues  or  profitable  operations.

     This  new  aspect  of  our business will focus on SNPs, one type of genetic
variation.  The  role  of  SNPs  in  disease  and  drug  response  is  not fully
understood, and relatively few, if any, therapeutic or diagnostic products based
on  SNPs  have  been developed and commercialized. Among other things, demand in
this  area  may  be  adversely affected by ethical and social concerns about the
confidentiality  of  patient-specific  genetic  information and about the use of
genetic  testing  for  diagnostic  purposes.

     Except  for  a few anecdotal examples, there is no proof that SNPs have any
correlation to diseases or a patient's response to a particular drug or class of
drug.  Identifying  statistically significant correlations is time-consuming and
could involve the collection and screening of a large number of patient samples.
We  do  not  know  if the SNPs we have discovered to date are suitable for these
correlation  studies.  Nor  do  we  currently have access to the patient samples
needed  or  technology  allowing  us  to  rapidly  and cost-effectively identify
pre-determined  SNPs  in  large  numbers  of  patients.

     Most  SNPs  may  occur  too  infrequently to warrant their use in analyzing
patients'  genetic  variation.  We  may  have trouble identifying SNPs that both
correlate with diseases or drug responses and occur frequently enough to justify
their  use  by  pharmaceutical  companies.

     Our  success  will also depend upon our ability to develop, use and enhance
new  and relatively unproven technologies. Our strategy of using high-throughput
mutation  detection  processes and sequencing to identify SNPs and genes rapidly
is  unproven.  Among other things, we will need to improve the throughput of our
SNP-discovery  technology.  We  may  not  be  able  to  achieve  these necessary
improvements,  and  other  factors  may  impair  our  ability  to  develop  our
SNP-related  products  and  services  in  time  to  be  competitively available.

OUR  STRATEGIC  INVESTMENTS  MAY  RESULT  IN  LOSSES  AND  OTHER ADVERSE EFFECTS

     We  make  strategic  investments  in  joint  ventures  or  businesses  that
complement  our business. These investments, such as our investment in diaDexus,
may:

- -     often  be made in securities lacking a public trading market or subject to
trading  restrictions,  either  of  which  increases  our  risk  and reduces the
liquidity  of  our  investment,

- -     require  us  to  record  losses  and  expenses  related  to  our ownership
interest,

- -     require  us  to  record  charges  related to the acquisition of in-process
technologies or for the impairment in the value of the securities underlying our
investment,  and

- -     require  us  to  invest  greater  amounts  than  anticipated  or to devote
substantial  management  time  to  the  management  of  research and development
relationships  and  joint  ventures.

     The  market values of many of these investments fluctuate significantly. We
evaluate  our  long-term  equity investments for impairment of their values on a
quarterly  basis.  Impairment  could  result  in future charges to our earnings.
These  losses  and  expenses  may  exceed  the  amounts  that  we  anticipated.



OUR  SALES  CYCLE  IS  LENGTHY

     Our ability to obtain new subscribers for our databases, software tools and
microarray  and other services depends upon prospective subscribers' perceptions
that  our  products and services can help accelerate drug discovery efforts. Our
sales  cycle  is  typically  lengthy  because  we  need to educate our potential
subscribers  and  sell  the  benefits  of our tools and services to a variety of
constituencies within potential subscriber companies. In addition, each database
subscription  and  microarray  services  agreement  involves  the negotiation of
unique  terms.  We  may  expend  substantial funds and management effort with no
assurance  that  a  subscription  or  services agreement will result. Actual and
proposed consolidations of pharmaceutical companies have affected the timing and
progress  of  our  sales  efforts. We expect that future proposed consolidations
will  have  similar  effects.

PATENTS  AND  OTHER  PROPRIETARY  RIGHTS  PROVIDE  UNCERTAIN  PROTECTION

     WE  MAY BE UNABLE TO PROTECT OUR PROPRIETARY INFORMATION.  Our business and
competitive position depend upon our ability to protect our proprietary database
information  and  software technology, but our strategy of obtaining proprietary
rights in as many genes and SNPs as possible is unproven. Despite our efforts to
protect  this  information  and  technology, unauthorized parties may attempt to
obtain  and use information that we regard as proprietary. Although our database
subscription  agreements  require  our  subscribers  to  control  access  to our
databases,  policing  unauthorized  use  of  our  databases  and software may be
difficult.

     We  have been issued a number of patents with respect to the gene sequences
in  our  databases  and  have  filed  for  patents  on  selected features of our
software.  However,  as of the date of this report, we have no issued patents or
registered  copyrights  for  that  software.  We  cannot  prevent  others  from
independently  developing software that might be covered by copyrights issued to
us,  and  trade  secret  laws  do  not  prevent  independent  development.

     We  pursue  a  policy  of  having  our  employees, consultants and advisors
execute proprietary information and invention agreements when they begin working
for us.  However, these agreements may not provide meaningful protection for our
trade  secrets or other proprietary information in the event of unauthorized use
or  disclosure.

     Our  means of protecting our proprietary rights may not be adequate and our
competitors  may:

- -     independently develop substantially equivalent proprietary information and
techniques,

- -     otherwise  gain  access  to  our  proprietary  information,  or

- -     design  around  patents  issued  to us or our other intellectual property.

     OUR PATENT APPLICATIONS MAY CONFLICT WITH OTHERS.  Our current policy is to
file  patent applications on what we believe to be novel full-length and partial
gene  sequences obtained through our gene sequencing efforts. We have filed U.S.
patent  applications in which we have claimed certain partial gene sequences. We
have  also  applied  for  patents  in  the  U.S.  and  other  countries claiming
full-length  gene  sequences  associated  with cells and tissues involved in our
gene  sequencing program. We hold a number of issued U.S. patents on full-length
genes  and  one  issued  U.S. patent claiming multiple partial gene sequences. A
number  of  entities  make  certain gene sequences publicly available, which may
adversely  affect  our  ability  to  obtain  patents  on  those  genes.

     We  believe  that some of our patent applications claim genes that may also
be  claimed  in  patent  applications  filed  by others. In some or all of these
applications, a determination of priority of inventorship may need to be decided
in  an  interference  before  the  United  States  Patent  and  Trademark Office
("USPTO").

     The  Board  of Patent Appeals and Interferences has declared  interferences
with  respect  to  two  patent  applications  directed  to  technology  licensed
exclusively  to  us  and  two  Affymetrix  patents  that  are the subject of our
litigation  with  Affymetrix.  The Board of Patent Appeals has also declared two
interferences  involving applications covering Incyte full-length genes, and has
advised  us  of  approximately  a  dozen  additional interferences that might be
declared.  We  cannot predict whether any of the interferences would be resolved
in  our  favor.  Regardless of the outcome, interferences could be expensive and
time-consuming.

     ENFORCEMENT  OF  GENE  PATENTS  IS  UNCERTAIN.  One of our strategies is to
obtain  proprietary  rights  in as many genes (including partial gene sequences)
and  SNPs  as  possible. While the USPTO has issued patents covering full-length
genes, partial gene sequences and SNPs, we do not know whether or how courts may
enforce  those  patents, if that becomes necessary. If a court finds these types
of  inventions  to be unpatentable, or interprets them narrowly, the benefits of
our  strategy  may  not  materialize.

     WE  MAY  DECIDE  TO  ABANDON  PATENT  APPLICATIONS.  The  USPTO  has  had a
substantial  backlog  of  biotechnology  patent applications, particularly those
claiming  gene  sequences.  In  1996,  the  USPTO issued guidelines limiting the
number  of  partial  gene  sequences that can be examined within a single patent
application. Many of our patent applications contain more partial sequences than
the  maximum  number allowed under these guidelines. Due to the resources needed
to  comply with the guidelines, we may decide to abandon patent applications for
some  of  our  partial  gene  sequences.

     Because  filing large numbers of patent applications and maintaining issued
patents can be very costly, we may choose not to pursue every application. If we
do  not  pursue  patent  protection  for all of our full-length and partial gene
sequences, the value of our intellectual property portfolio could be diminished.
Because  of  the  possible  delay  in  obtaining allowance of some of our patent
applications,  and  the  secrecy of patent applications, we do not know if other
applications  having  priority  over  ours  have  been  filed.

     WE  MAY  NEED  TO REFILE SOME OF OUR PATENT APPLICATIONS, AND THE PERIOD OF
PATENT  PROTECTION HAS BEEN SHORTENED.  The value of our patents depends in part
on  their duration. The U.S. patent laws were amended in 1995 to change the term
of  patent  protection  from  17 years from patent issuance to 20 years from the
earliest effective filing date of the application. Because the average time from
filing to issuance of biotechnology applications is at least one year and may be
more  than  three  years  depending on the subject matter, a 20-year patent term
from  the  filing  date  may  result in substantially shorter patent protection,
which may adversely affect our rights under any patents that obtain. We may need
to  refile  applications  claiming large numbers of gene sequences and, in these
situations,  the  patent  term  will  be  measured from the date of the earliest
priority  application.  This  would  shorten  our  period of patent exclusivity.

     INTERNATIONAL  PATENT  PROTECTION  IS PARTICULARLY UNCERTAIN. Biotechnology
patent  law  outside  the  United States is even more uncertain and is currently
undergoing  review  and  revision  in many countries.  Further, the laws of some
foreign  countries  may not protect our intellectual property rights to the same
extent  as  U.S. laws. We may participate in opposition proceedings to determine
the  validity  of our or our competitors' foreign patents, which could result in
substantial  costs  and  diversion  of  our  efforts.

WE  MAY  BE  SUBJECT  TO  ADDITIONAL  LITIGATION  AND  INFRINGEMENT  CLAIMS

     The  technology  that  we  use  to  develop our products, and those that we
incorporate  in  our  products,  may be subject to claims that they infringe the
patents or proprietary rights of others. The risk of this occurring will tend to
increase  as  the  genomics,  biotechnology and software industries expand, more
patents  are  issued  and other companies attempt to discover genes and SNPs and
engage  in  other  genomic-related  businesses.

     As  is  typical  in the genomics, biotechnology and software industries, we
have  received,  and  we will probably receive in the future, notices from third
parties  alleging patent infringement. We believe that we are not infringing the
patent rights of any such third party. Except for Affymetrix, no third party has
filed  a  patent  lawsuit  against  us.

     We  may,  however,  be  involved  in  future  lawsuits  alleging  patent
infringement  or  other  intellectual  property  rights violations. In addition,
litigation  may  be  necessary  to:

- -     assert  claims  of  infringement,

- -     enforce  our  patents,

- -     protect  our  trade  secrets  or  know-how,  or

- -     determine the enforceability, scope and validity of the proprietary rights
of  others.

     We  may be unsuccessful in defending or pursuing these lawsuits. Regardless
of  the  outcome,  litigation  can  be  very  costly and can divert management's
efforts.  An  adverse determination may subject us to significant liabilities or
require  us to seek licenses to other parties' patents or proprietary rights. We
may  also be restricted or prevented from manufacturing or selling our products.
Further,  we  may  not  be  able  to obtain the necessary licenses on acceptable
terms,  if  at  all.

WE  MAY  ENCOUNTER  PROBLEMS  IN  MEETING  CUSTOMERS'  SOFTWARE  NEEDS

     Our  databases  also  require software support and will need to incorporate
features  determined  by  database  collaborators.  If  we  experience delays or
difficulties  in  implementing  our  database software or collaborator-requested
features,  we  may  be  unable  to  service  our  collaborators.

OUR  RECENT  ACQUISITIONS  INVOLVE  SEVERAL  RISKS

     Our acquisitions of Synteni and Hexagen involve several potential operating
and  business  risks,  including  potential  problems  and costs associated with
integrating Synteni's and Hexagen's businesses, technologies and management with
ours.  Our  integration  efforts  may  also  result in the loss of efficiency or
employees.

     The  combined  companies  may  not realize any revenue enhancements or cost
savings.  Increases in other expenses and operating losses, including losses due
to problems in integrating the acquired companies with ours, may offset any cost
savings.  Our  combined  operating  results  and  financial condition may not be
superior  to  what we could have achieved without these acquisitions, even if we
integrate  the  acquired  business  efficiently,  effectively  and quickly.  The
combination  of  these  businesses with ours may also take longer than expected.

     In  particular,  we began our integration of Hexagen recently. We will need
to  integrate  Hexagen's technology with our existing technology and improve its
throughput,  in  order  to develop SNP programs. We may be unable to achieve the
necessary  improvements,  which  could slow our efforts to develop a SNP-related
business.  Also,  since  Hexagen  is  located  in  England,  we  may  experience
difficulties  in integrating their operations with our U.S.-based operations. We
may also incur an expense if the goodwill and other intangible assets associated
with  the  Hexagen  purchase  are  determined  to  be  impaired  in  the future.

FUTURE  ACQUISITIONS  WILL  CREATE  RISKS  AND  UNCERTAINTIES

     As part of our business strategy, we may acquire other assets, technologies
and  businesses. We acquired two companies in 1996, Synteni in January 1998, and
Hexagen  in  September  1998.

     These  and  any  future  acquisitions  involve risks such as the following:

- -     we  may  be  exposed  to  unknown  liabilities  of  acquired  companies;

- -     our  acquisition  and  integration costs may be higher than we anticipated
and  may  cause  our  quarterly  and  annual  operating  results  to  fluctuate;

- -     we  may  experience  difficulty and expense in assimilating the operations
and  personnel of the acquired businesses, disrupting our business and diverting
management's  time  and  attention;

- -     we  may be unable to integrate or complete the development and application
of  acquired  technology;

- -     we  may  experience  difficulties  in establishing and maintaining uniform
standards,  controls,  procedures  and  policies;

- -     our  relationships  with  key  customers  of  acquired  businesses  may be
impaired, due to changes in management and ownership of the acquired businesses;

- -     we  may  be  unable  to  retain  key employees of the acquired businesses;

- -     we  may  incur  amortization  expenses  if  an  acquisition  results  in
significant  goodwill  or  other  intangible  assets;  and

- -     our  stockholders may be diluted if we pay for the acquisition with equity
securities.

     In  addition, if we acquire additional businesses that are not located near
our  Palo  Alto,  California  headquarters,  we  may  experience more difficulty
integrating  and  managing  the  acquired  businesses'  operations.

WE  MAY  HAVE  DIFFICULTY  MANAGING  OUR  GROWTH

     We expect to continue to experience significant growth in the number of our
employees  and  the  scope  of  our  operations. This growth has placed, and may
continue  to  place,  a significant strain on our management and operations. Our
ability  to  manage  this  growth  will  depend  upon our ability to broaden our
management  team  and our ability to attract, hire and retain skilled employees.
Our success will also depend on the ability of our officers and key employees to
continue to implement and improve our operational and other systems and to hire,
train  and  manage  our  employees.

     In  addition,  we  must continue to invest in customer support resources as
the  number  of  database collaborators and their requests for support increase.
Our  database  collaborators typically have worldwide operations and may require
support at multiple U.S. and foreign sites. To provide this support, we may need
to  open  offices  in addition to our Palo Alto, California headquarters and our
offices  in  Fremont,  California,  St.  Louis, Missouri and Cambridge, England,
which  could  result  in  additional  burdens  on  our  systems  and  resources.

WE  DEPEND  ON  KEY  EMPLOYEES  IN  A  COMPETITIVE  MARKET FOR SKILLED PERSONNEL

     We  are  highly  dependent  on  the  principal  members  of our management,
operations and scientific staff, including Roy A. Whitfield, our Chief Executive
Officer,  and  Randal  W. Scott, our President and Chief Scientific Officer. The
loss  of  either of these persons' services would have a material adverse effect
on  our  business. We have not entered into any employment agreement with either
of  these  persons and do not maintain a key person life insurance policy on the
life  of  any  employee.

     Our future success also will depend in part on the continued service of our
key  scientific,  software,  bioinformatics  and  management  personnel  and our
ability  to  identify,  hire and retain additional personnel, including customer
service,  marketing  and  sales  staff.  We  experience  intense competition for
qualified  personnel.  We  may  not  be  able  to continue to attract and retain
personnel  necessary  for  the  development  of  our  business.

WE  DEPEND  ON  THIRD  PARTIES  FOR  NECESSARY  EQUIPMENT,  SUPPLIES  AND  DATA

     WE  RELY  ON  A  SMALL  NUMBER OF SUPPLIERS OF GENE SEQUENCING MACHINES AND
REAGENTS  REQUIRED  FOR GENE SEQUENCING.  Although we are evaluating alternative
gene  sequencing machines, they may not be available in sufficient quantities or
at  acceptable costs. In addition, if a third party claims that our use of these
machines  infringes  their patent rights, our use of these machines could become
more  costly  or  could  be  prevented.  If  we  are unable to obtain additional
machines  or  an  adequate supply of reagents or other materials at commercially
reasonable  rates,  our  ability  to  identify genes and SNPs would be adversely
affected.

     WE RELY ON OUTSIDE SOURCES FOR TISSUE SAMPLES FROM WHICH WE ISOLATE GENETIC
MATERIAL USED IN OUR OPERATIONS.  Our business could be adversely affected if we
lose  access  to some of these sources, or if they charged us higher access fees
or imposed tighter restrictions on our use of the information generated from the
samples.

     WE  CANNOT  CONTROL  THE  PERFORMANCE  OF  COLLABORATORS. We may enter into
research and development relationships with corporate and academic collaborators
and  others.  The  success  of  these  relationships depends upon third parties'
performance  of  their  responsibilities.  Our  ability  to  develop  these
relationships  is  uncertain,  and  any  established  relationships  may  prove
unsuccessful. Our collaborators may also be pursuing alternative technologies or
developing  alternative  products  on their own or in collaboration with others,
including  our  competitors.

     WE  RELY ON THIRD-PARTY DATA SOURCES.  We rely on scientific and other data
supplied  by  others, including our academic collaborators and sources of tissue
samples.  These  data could contain errors or other defects, which could corrupt
our  databases.  In addition, we cannot guarantee that our data sources acquired
this  information  in  compliance  with  legal  requirements. If either of these
happen  and  become  known,  our business prospects could be adversely affected.

OUR  BUSINESS  COULD  BE  AFFECTED  BY  THE  YEAR  2000  ISSUE

     As  a  result  of  computer programs being written using two digits, rather
than  four, to represent year dates, the performance of our computer systems and
those of our suppliers and customers in the Year 2000 is uncertain. Any computer
programs  that  have  time-sensitive software may recognize a date using "00" as
the  year  1900 rather than the year 2000. This could result in a system failure
or  miscalculations  which disrupt our operations, such as a temporary inability
to  process  transactions,  send  invoices  or  engage  in other normal business
activities.

     We  are evaluating the Year 2000 readiness of the software products that we
sell,  the  information technology systems used in our operations, and our other
systems  such  as  building security and voicemail. This project consists of the
following  phases:

- -     identifying  all  of our software products, information technology systems
and  other  systems;

- -     assessing  repair  or  replacement  requirements;

- -     repair  or  replacement;

- -     testing;

- -     implementation;  and

- -     creating  contingency  plans  in  the  event  of  Year  2000  failures.

     We  have  completed  testing  of  all  current  versions  of  our  software
products, which disclosed nothing that results in Year 2000 non compliance. Even
so,  whether a complete system or device in which a software product is embedded
will  operate  correctly  for  an  end-user  depends  largely  on  the Year 2000
compliance  of  other  components,  most of which are supplied by third parties.

     We  rely,  both  domestically  and  internationally,  upon various vendors,
government  agencies,  utility  companies, telecommunications service companies,
delivery  service companies and other service providers. We have no control over
these  third  parties  and  they  may  suffer  a  Year 2000 business disruption.

     We  also  rely  upon goods and services purchased from certain vendors, and
our business could be disrupted if they fail to adequately address the Year 2000
issue.  We are surveying our principal vendors to assess the potential effect of
the  Year  2000 issue on their ability to supply us. We cannot currently predict
the  outcome  of  this  effort. We intend to develop contingency plans regarding
vendors  whose  failure  to  be  Year  2000 ready is expected to have a material
adverse  impact  on our operations. However, our vendors may be unable to supply
important  goods  and services without material interruption and our contingency
plans  may  not  keep  us  adequately  supplied.

     The  demand  for  our  products  could also be affected by Year 2000 issues
affecting  our  customers.  We  plan to develop a contingency plan for customers
with  Year 2000 problems, but we cannot presently determine what impact, if any,
it  will  have.

     We  intend  to develop and implement, if necessary, appropriate contingency
plans  to mitigate the effects of any Year 2000 noncompliance. We expect to have
these  plans completed in the second half of 1999. As part of the development of
a  contingency  plan,  we  will  evaluate  our worst case scenario for Year 2000
noncompliance.  Although  the  full consequences are unknown, the failure of our
critical systems or those of our material vendors and other business partners to
be  Year  2000  complaint  would  interrupt  our  business.

OUR  ACTIVITIES  INVOLVE HAZARDOUS MATERIALS AND MAY SUBJECT US TO ENVIRONMENTAL
LIABILITY

     Our  research  and development involves the controlled use of hazardous and
radioactive materials and biological waste. We are subject to federal, state and
local laws and regulations governing the use, manufacture, storage, handling and
disposal of these materials and certain waste products. Although we believe that
our  safety procedures for handling and disposing of these materials comply with
legally  prescribed  standards,  the  risk of accidental contamination or injury
from  these  materials  cannot  be  completely  eliminated.  In  the event of an
accident,  we  could be held liable for damages, and this liability could exceed
our  resources.

     We  believe  that  we  are  in  compliance  in  all  material respects with
applicable  environmental  laws  and  regulations and currently do not expect to
make  material  additional  capital  expenditures  for  environmental  control
facilities  in the near term. However, we may have to incur significant costs to
comply  with  current  or  future  environmental  laws  and  regulations.

OUR  REVENUES  ARE  DERIVED  PRIMARILY FROM THE PHARMACEUTICAL AND BIOTECHNOLOGY
INDUSTRIES

     We  expect  that  our  revenues  in  the foreseeable future will be derived
primarily  from  products  and  services  provided  to  the  pharmaceutical  and
biotechnology industries. Accordingly, our success will depend directly upon the
success  of  the  companies  within  these  industries  and their demand for our
products  and services. Our operating results may fluctuate substantially due to
reductions  and  delays in research and development expenditures by companies in
these  industries.  These reductions and delays may result from factors such as:

- -     changes  in  economic  conditions;

- -     changes  in  the  regulatory  environment affecting health care and health
care  providers;

- -     pricing  pressures;

- -     market-driven  pressures on companies to consolidate and reduce costs; and

- -     other  factors  affecting  research  and  development  spending.

These  factors  are  not  within  our  control.

WE  MAY  NEED  TO  RAISE  ADDITIONAL  CAPITAL  THAT  MAY  NOT  BE  AVAILABLE

     Based  upon  our  current plans, we believe that our existing resources and
anticipated cash flow from operations can satisfy our capital needs for at least
the  next  twelve  months.  However,  our  products and services may not produce
revenues  which,  together  with  our  existing  cash  and  other resources, are
adequate  to  meet  our  cash  needs.  Our  cash requirements depend on numerous
factors,  including:

- -     our  ability  to  attract  and  retain collaborators for our databases and
other  products  and  services;

- -     expenditures  in  connection  with  alliances,  license  agreements  and
acquisitions  of  and  investments in complementary technologies and businesses;

- -     the  need  to  increase  research  and development spending as a result of
competing  technological  and  market  developments;

- -     the cost of filing, prosecuting, defending and enforcing patent claims and
other  intellectual  property  rights;

- -     the  purchase  of  additional  capital  equipment,  including  equipment
necessary  to  process  data for our databases and to ensure that our sequencing
and  microarray  operations  remain  competitive;

- -     capital  expenditures  required  to  expand  our  facilities;  and

- -     costs  associated  with  the  integration  of  acquired  operations.

     Changes  in  our  research and development plans or other changes affecting
our  operating  expenses  may alter the timing and amount of expenditures of our
capital  resources. If we need additional funding, we may be unable to obtain it
on  favorable terms, or at all. If adequate funds are not available, we may have
to  curtail  operations  significantly  or  obtain  funds  by  entering  into
arrangements requiring us to relinquish rights to certain technologies, products
or  markets.  In  addition,  if  we  raise funds by selling stock or convertible
securities,  our  existing  stockholders  could  suffer  dilution.

OUR  BUSINESS  COULD  BE  INTERRUPTED  BY  NATURAL  DISASTERS

     We conduct our sequencing and a significant portion of our other activities
at  our  facilities in Palo Alto, California, and conduct our microarray-related
activities  at  our  facilities  in Fremont, California. Both locations are in a
seismically  active  area. Although we maintain business interruption insurance,
we do not have or plan to obtain earthquake insurance. A major catastrophe (such
as  an  earthquake  or  other  natural  disaster)  could  result  in a prolonged
interruption  of  our  business.



PART  I:  FINANCIAL  INFORMATION
ITEM  3:  QUANTITATIVE  AND  QUALITATIVE  DISCLOSURES  ABOUT  MARKET  RISK

     The  Company  is  exposed  to  interest  rate  risk  primarily  through its
investments  in  short-term  marketable  securities  and  its  note payable. The
Company's  investment  policy  calls  for  investment  in  short  term, low risk
instruments. As of June 30, 1999, investments in marketable securities was $52.8
million.  At June 30, 1999, the Company had a fixed rate note payable balance of
$0.6  million.  Due to the nature of these investments and note, any decrease in
rates  is  not  expected  to  have  a material impact on the Company's financial
statements.

The Company is exposed to equity price risks on the marketable portion of equity
securities  included  in its portfolio of investments and long-term investments,
entered into to further its business and strategic objectives. These investments
are  in  small  capitalization  stocks  in  the  pharmaceutical/biotech industry
sector, in companies which the Company has research and development or licensing
agreements.  The  Company  typically does not attempt to reduce or eliminate its
market exposure on these securities. As of June 30, 1999, long-term investments,
excluding  diaDexus,  were  $12.8  million.

     The  Company  typically  does  not  hedge  its  foreign  currency exposure.
Management does not believe that the Company's exposure to foreign currency rate
fluctuations  is  material.


PART  II:   OTHER  INFORMATION

ITEM  1     Legal  Proceedings

     On  January 6, 1998, Affymetrix, Inc. ("Affymetrix") filed a lawsuit in the
United  States  District  Court  for  the  District  of  Delaware,  subsequently
transferred  to  the  United  States District Court for the Northern District of
California,  alleging  infringement  of  U.S. patent number 5,445,934 (the "'934
Patent")  by both Synteni and Incyte. The complaint alleges that the '934 Patent
has  been  infringed  by  the making, using, selling, importing, distributing or
offering  to sell in the U.S. high density arrays by Synteni and Incyte and that
such infringement was willful. Affymetrix seeks a permanent injunction enjoining
Synteni  and  Incyte  from  further  infringement  of  the  '934  Patent and, in
addition,  seeks  damages,  costs  and  attorney's fees and interest. Affymetrix
further  requests  that  any  such damages be trebled based on its allegation of
willful  infringement  by  Incyte  and  Synteni.

     In  September  1998,  Affymetrix  filed an additional lawsuit in the United
States  District Court for the District of Delaware, subsequently transferred to
the  United  States  District  Court  for the Northern District of California in
November  1998,  alleging  infringement of the U.S. patent number 5,800,992 (the
"'992  Patent")  and  U.S.  patent  number 5,744,305 (the "'305 Patent") by both
Synteni  and  Incyte.  The  complaint  alleges  that  the  '305  Patent has been
infringed  by the making, using, selling, importing, distributing or offering to
sell  in  the  United States high density arrays by Synteni and Incyte, that the
'992  Patent  has  been  infringed  by  the  use of Synteni's and Incyte's GEMTM
microarray  technology  to  conduct  gene  expression monitoring using two-color
labeling,  and  that such infringement was willful. Affymetrix seeks a permanent
injunction  enjoining  Synteni  and Incyte from further infringement of the '305
and  '992  Patents  and,  in  addition,  Affymetrix  had  sought  a  preliminary
injunction  enjoining  Incyte  and Synteni from using Synteni's and Incyte's GEM
microarray  technology  to  conduct  gene  expression monitoring using two-color
labeling as described in the '992 Patent. Affymetrix's request for a preliminary
injunction  was denied in April 1999 and the lawsuit is tentatively scheduled to
go  to  trial  in  July  2000.

     In  April  1999,  the  Board  of Patent Appeals and Interferences of United
States  Patent and Trademark Office (PTO) declared interferences between pending
patent  applications  licensed exclusively to Incyte and the Affymetrix '305 and
'992  Patents.  An  interference proceeding is invoked by the PTO when more than
one  patent applicant claims the same invention. The Board of Patent Appeals and
Interferences  evaluates all relevant facts, including those bearing on first to
invent, validity, enablement and scope of claims, and then makes a determination
as  to  who,  if  anyone,  is  entitled to the patent on the disputed invention.

     Incyte  and  Synteni  believe  they have meritorious defenses and intend to
defend  the suits vigorously. However, there can be no assurance that Incyte and
Synteni  will  be  successful  in  the defense of these suits. At this time, the
Company cannot reasonably estimate the possible range of any loss resulting from
these suits due to uncertainty regarding the ultimate outcome. Regardless of the
outcome,  this  litigation has resulted and is expected to continue to result in
substantial  expenses  and  diversion of the efforts of management and technical
personnel.  Further,  there  can  be  no  assurance that any license that may be
required as a result of this suit or the outcome thereof would be made available
on  commercially  acceptable  terms,  if  at  all.
