                                     PART I


ITEM 1.           BUSINESS

         Except for the historical  information  contained herein, the following
discussion   contains   forward-looking   statements   that  involve  risks  and
uncertainties.  The Company's actual results could differ  materially from those
discussed  here.  Factors  that could cause or  contribute  to such  differences
include,  but are not limited to, those discussed in this section, as well as in
the section entitled "Item 7. Management's  Discussion and Analysis of Financial
Condition and Results of Operations."

         Lynx  Therapeutics,  Inc.  ("Lynx" or the "Company") was formed in late
1992 to discover  and target  inappropriate  gene  expression  in  disease.  The
Company's early efforts relied on academic  collaborations for the discovery and
understanding of altered or inappropriate gene function and on its own expertise
in synthetic DNA ("oligodeoxynucleotide" or "ODN") chemistry for the development
of  compounds  aimed at  modulating  undesirable  gene  expression.  These early
collaborations  resulted  in  a  number  of  compounds.  One  compound  for  the
prevention of restenosis  following balloon  angioplasty is in Phase II clinical
trials  in  Europe  and is  the  object  of  development  and  commercialization
agreements with two  pharmaceutical  companies.  The other  compounds,  aimed at
certain leukemias and cancers,  are currently the objects of in-vivo preclinical
studies.

         As  successful as these  programs  have been, their  progress  has been
generally constrained by the inherent difficulties of elucidating gene functions
with current  technologies.  As a result,  the Company has undertaken to acquire
and develop novel gene  identification  technologies  that promise to accelerate
the discovery and validation of important new targets.

         In   addition,   the  Company  has   recently   initiated  an  internal
biology-based drug discovery program designed around in vitro and in vivo models
of acute  biological  stress or injury.  This  program is  currently  focused on
models relevant to diseases  resulting from brain and spinal cord injuries.  Its
aim is to better define and characterize  gene function and  inappropriate  gene
expression in the diseases of interest.


LYNX  TECHNOLOGIES

Target Discovery Technologies

Massively Parallel Signature Sequencing  ("MPSS")

         In 1994 the Company  established a group to focus on the development of
new and  proprietary  DNA  sequencing  technologies  that  would be  capable  of
accelerating  the  discovery  and  validation  of  targets  for drug  discovery.
Foremost among these are the Massively  Parallel Signature  Sequencing  ("MPSS")
and the Massively Parallel Genomic Sequencing ("MPGS")  technologies.  The first
is designed to enable  researchers to identify a majority of all genes expressed
by a cell  (or  tissue)  from the  simultaneous  sequencing  of up to a  million
molecules  representing  that cell's (or  tissue's)  full gene  expression.  The
second is  designed  to enable the  simultaneous  sequencing  of up to a million
genomic fragments in order to arrive rapidly at genomic  sequences.  The Company
is currently refining various aspects of the biochemistries and  instrumentation
needed to  implement  these  technologies.  Barring  unforeseen  obstacles,  the
Company expects to deploy MPSS in its internal  research  programs as well as in
the programs of its customers and research  partners  during 1997,  and MPGS for
its own programs shortly thereafter.


                                       2.

Biology-based Target Discovery Programs

         In  1995  the  Company   established  a  target   discovery  and  early
development program designed to capitalize  eventually on the power of MPSS, but
which could develop  nevertheless  with expertise and intermediate  technologies
currently  resident  within  Lynx.  The  initial  projects  are  centered on the
medically important field of neurovascular  diseases, in areas for which good in
vitro and in vivo models  exist,  and that are well suited to eventual  analyses
with the Company's gene sequencing and target discovery MPSS technologies.

         Various  forms of  sub-lethal  stress or challenge  that will not cause
cellular  or tissue  injury are known to lead to states  wherein  certain  cells
become protected from subsequent  injury.  It is as if the cells have protective
reserves which are quiescent under normal resting  conditions,  but which become
activated upon sub-lethal challenges.  Examples include ischemic conditioning of
myocardial  muscle  cells,  liver  cells,  neurons,  and  depolarization-induced
conditioning  of  neurons.  Therefore,  analyzing  the  genes  induced  by  such
challenges could reveal endogenous  protective mechanisms which could then serve
as targets for drug development.

         Animal models of hypoxic  ischemic  nervous  system  injuries  (stroke,
global   ischemias)   reproduce   similar  human  conditions   reasonably  well.
Experiments in these models can be planned and timed  conveniently.  Stroke, for
example, can be modeled by blocking flow in a specific cerebral artery.  Tissues
can then be collected  from various  brain  regions,  and at desired time points
following the original insult. Thus,  progression of post-ischemic events can be
monitored  in affected  and  unaffected  hemispheres  to gain  insight  into the
molecular  pathologies  of the  modeled  disease.  Similar  models  exist  which
reproduce  certain  psychiatric  disorders  such as  depression.  Lynx is in the
process of studying such models of neurological  and psychiatric  diseases using
differential  molecular analysis  techniques.  These models include, but are not
limited to, those of hypoxic  ischemic brain injury,  epilepsy,  central nervous
system trauma,  depression,  and age-related memory deficits. By deciphering the
mechanisms  involved,  Lynx  expects  to  identify  potential  targets  for drug
developments.

Oligodeoxynucleotide Chemistries

         Oligodeoxynucleotides  or ODNs are short,  synthetic  DNA or DNA analog
fragments. Interest in their use stems from their ability, when synthesized with
the appropriate sequence, to bind to target mRNA molecules (the antisense mode),
or, in special cases, to double  stranded DNA (the antigene  mode),  and thereby
block or interfere with gene expression.

         ODN analogs are usually preferred over "natural" ODNs as the latter are
readily degraded by cellular  enzymes.  Lynx has expertise with two types of ODN
analogs, phosphorothioates, a class of compounds licensed from the United States
National  Institute of Health,  and  phosphoramidates,  a  proprietary  class of
compounds developed by the Company.

         ODNs can be used  both as  therapeutic  compounds  or as tools in model
experiments  to  block  expression  of a  given  gene in  order  to  validate  a
hypothesized   function.   Lynx  expects  its  ODN  expertise  and   proprietary
technologies to play a significant role in the discovery of gene function and in
the early and specific validation of potential drug targets.


CLINICAL AND PRE-CLINICAL PROGRAMS

Oligodeoxynucleotide Therapeutic Programs

         Lynx's ODN drug clinical  development  program is currently  focused on
evaluating  in humans the  efficacy  observed  earlier in porcine  models,  of a
proprietary phosphorothioate ODN antisense compound, LR-3280, in coronary artery
restenosis following balloon angioplasty.


                                       3.
<PAGE>

         The target of LR-3280 is the c-myc  oncogene  whose dynamic  expression
suggests  that it plays a causal  role in the  pathologic  process  of  arterial
restenosis.  Lynx's  restenosis  program is an early example of intervening in a
specific disease process by targeting  inappropriate  gene expression.  Lynx has
completed a Phase I safety study of LR-3280 in humans and has  commenced a Phase
II  efficacy  study in Europe.  The  Company has also  completed  two  corporate
development and marketing  partnerships to fully support clinical development of
this compound in North America, Europe, Japan and certain Asian countries.

         The Company and its  collaborators  are now  conducting in vitro and in
vivo  pre-clinical  studies  of a  number  of  phosphoramidate  drug  candidates
targeting   proliferative   diseases  and  viruses.  The  potential  utility  of
phosphoramidate  ODNs as direct antigene drugs is especially promising since the
number of copies of a target  gene in a cell is usually  two,  not  hundreds  or
thousands as with many target mRNA  molecules and viruses.  Thus,  the effective
intracellular  concentration  required  of an  "antigene"  ODN may be many times
lower than that of an "antisense" ODN drug.  Antigene ODNs also have interesting
implications   for  treating  viral  diseases  that  involve  the  viral  genome
integrating itself into the host genome once or a few times--as does HIV.

Process Development and Manufacturing

         The  development  of  ODN-based  drugs  requires the ability to produce
amounts of  synthetic  DNA far  larger  than those  which can be  obtained  from
research-oriented DNA synthesizers. Few other sources can match the quantity and
quality  of  phosphorothioate   compounds  that  Lynx's  process  chemistry  and
synthetic  technology  have made available for in vitro, in vivo, and now human,
testing.  This  manufacturing  technology traces its origins to the beginning of
Lynx as a division of Applied Biosystems Inc., ("ABI"), now a division of Perkin
Elmer  Corporation.  Lynx retains  royalty-free  licenses to ABI's DNA synthesis
technologies and holds exclusive positions in the therapeutics field for some of
them.

         The development of phosphoramidate  analogs has necessitated  extensive
process  development  research to enable their  manufacture  as their  synthesis
requires different chemistries than those developed previously for DNA and other
analogs.  Progress  to date  has  resulted  in  making  the  phosphoramidates  a
practical alternative in addition to being a more potent and versatile one.

Business Risks

Technological Uncertainty; Government Regulation

         All of Lynx's  products are in a research  and  development  phase;  no
significant  revenues have been generated from services or product sales.  There
is no assurance that Lynx's  technologies will be successfully  developed or, if
they are, that they can be successfully  marketed.  Certain Lynx products depend
on the continuance of outside  collaborations and/or the development of in-house
expertise  to  complement  the  efforts of such  collaborators.  There can be no
assurance that Lynx will successfully  maintain these  collaborations or that it
will be able to develop such in-house  expertise.  Moreover,  Lynx's products in
research  or  development  may prove to have  undesirable  and  unintended  side
effects or other characteristics that may prevent or limit their commercial use.
Pharmaceutical or biotechnology  based products,  if any,  resulting from Lynx's
research and development programs are not expected to be commercially  available
for a number of years.

         The FDA and comparable agencies in foreign countries impose substantial
pre-market   approval   requirements   upon  the   introduction  of  therapeutic
pharmaceutical  products  through lengthy and detailed  preclinical and clinical
testing procedures and other costly and time-consuming procedures.  Satisfaction
of these requirements,  which includes  demonstrating to the satisfaction of the
FDA that the product is both safe and effective,  typically  takes several years
or more, depending on the type, complexity and novelty of the product. There can
be no  assurance  that  government  approval  will be obtained for any of Lynx's
products. Even if obtained,  regulatory approval of a product may not be granted
on a timely basis,  may impose  limitations  on the indicated uses for which the
product may be marketed or may impose costly compliance procedures, all of 


                                       4.

which could diminish any competitive advantage that Lynx may obtain.  Further, a
marketed product, its manufacturer and its manufacturing  facilities are subject
to continual review and periodic inspections and discovery of previously unknown
problems with a product,  manufacturer or facility may result in restrictions on
such product manufacturer,  including withdrawal of the product from the market.
Also, additional government regulation, legislation or administrative action may
be established  which could also prevent or delay regulatory  approval of Lynx's
products.

Loss History; Uncertainty of Future Profitability; Need for Additional Funds

         Lynx had an accumulated  deficit of approximately $31.5 million through
December 31, 1996 and expects to incur substantial operating losses for at least
the next several years. There can be no assurance that Lynx will ever be able to
achieve or  sustain  profitability.  See "Item 7.  Management's  Discussion  and
Analysis of Financial Condition and Results of Operations."

         Lynx's  operations to date have consumed  substantial  amounts of cash.
Negative cash flow from  operations is expected to continue and to increase over
the foreseeable  future.  Lynx anticipates  that its existing capital  resources
will enable Lynx to maintain its current and planned  operations  through  1997.
Lynx intends to seek additional  funding through future equity or debt offerings
in the public or private markets or through collaborative  arrangements.  Lynx's
ability  to obtain  additional  financing  will  depend on the  progress  in its
research  and  development   efforts,   its  financial  condition  and  business
prospects, and conditions prevailing in the relevant capital markets at the time
financing is sought.  There can be no assurance  that any  additional  financing
required by Lynx will be available or, if available,  will be on terms favorable
to  Lynx.  See  "Item 7.  Management's  Discussion  and  Analysis  of  Financial
Condition and Results of  Operations--Liquidity  and Capital Resources." Failure
to obtain  such  additional  funds would have a material  adverse  effect on the
Company.

Competition

         Lynx  is  subject  to  competition   from  many  directions   including
complementary  DNA ("cDNA") cloning and sequencing  technologies,  ODN chemistry
and drug development,  and the discovery and development of  pharmaceutical  and
biotechnology drugs. Competition in the latter arena includes all of the world's
pharmaceutical and biotechnology  companies that have research programs pursuing
the same general targets as Lynx, including cardiovascular diseases, cancers and
leukemias and neurovascular  diseases.  There are several companies that are now
actively engaged in technology developments and discovery programs pertaining to
genomic  elucidation and gene function  determination.  Key to these efforts are
cDNA cloning and DNA sequencing  techniques.  However, there can be no assurance
that  combinations  of  novel  cloning  and  sequencing  techniques  will not be
discovered or developed elsewhere. See "Lynx Technologies."

Patents and Proprietary Rights

         Lynx's  success  will  depend in part on its  ability to obtain  patent
protection for its products both in the U.S. and other countries. Lynx has filed
and will continue to file  applications,  as appropriate,  for patents  covering
both its products and  processes and has licensed a number of patents and patent
applications covering certain of its compounds.  Some of the patent applications
owned by Lynx have already  issued,  but no assurance  can be given that patents
will issue from any of the pending  applications  or that,  if patents do issue,
the claims allowed will be sufficiently broad to protect Lynx's  technology.  In
addition,  no assurance  can be given that any patents  issued to or licensed by
Lynx will not be challenged, invalidated, infringed or circumvented, or that the
rights granted thereunder will provide competitive advantages to Lynx.

         The  commercial  success  of Lynx will also  depend in part on Lynx not
infringing  patents  issued to  competitors  and on  others  not  breaching  the
technology  licenses upon which Lynx's products might be based.  There can be no
assurance  that  Lynx  will be able to  obtain  a  license  to any  third  party
technology  that it may require to conduct its business or that, if  obtainable,
such technology can be licensed at a reasonable cost.  Failure 

                                       5.

<PAGE>


by  Lynx  to  obtain  a  license  to  any  technology  that  it may  require  to
commercialize its technologies or products may have a material adverse effect on
Lynx.

         Litigation,  which could result in substantial  costs to Lynx, may also
be necessary to enforce any patents issued to Lynx or to determine the scope and
validity  of other  parties'  proprietary  rights.  If the  outcome  of any such
litigation is adverse to Lynx, Lynx's business could be adversely affected. Lynx
may have to participate in interference  proceedings declared by the U.S. Patent
and  Trademark  Office,  which  could  result  in  substantial  cost  to Lynx to
determine the priority of inventions.  Furthermore, Lynx may have to participate
at substantial cost in International  Trade Commission  proceedings to abate the
importation of products which would compete unfairly with products of Lynx.

         Lynx also relies on trade secrets and proprietary  expertise,  which it
seeks to protect in part by  confidentiality  agreements with its collaborators,
employees and consultants.  There can be no assurance that these agreements will
not be breached,  that Lynx would have adequate remedies for any breach, or that
its trade secrets will not otherwise become known or be independently  developed
by competitors.

Need to Establish Collaborative Relationships; Dependence on Partners

         Lynx's business strategy includes entering into strategic  alliances or
licensing  arrangements with corporate  partners,  primarily  pharmaceutical and
biotechnology  companies,  relating to the development and  commercialization of
certain of its potential technologies,  databases and products.  There can be no
assurance  that  Lynx  will  be  able  to  negotiate  attractive   collaborative
arrangements or that such collaborations will be available to Lynx on acceptable
terms so that any such relationships,  once established,  will be scientifically
or  commercially  successful.  In addition,  there can be no assurance  that the
Company  will be able to  maintain  its  existing  collaborations,  or that  the
Company's partners will perform under such collaborations.

Attraction and Retention of Key Employees and Consultants

         Lynx is highly dependent on the principal members of its management and
scientific  staff,  the loss of whose  services  could have a  material  adverse
effect on Lynx.  Furthermore,  recruiting  and  retaining  qualified  scientific
personnel to perform  research and  development  work in the future will also be
critical to Lynx's  success.  Lynx  believes it will be successful in attracting
and retaining skilled and experienced  scientific personnel,  although there can
be no assurance  that Lynx will be able to attract and retain such  personnel on
acceptable terms, given the competition among numerous pharmaceutical and health
care  companies,   universities   and  non-profit   research   institutions  for
experienced scientists. See "Employees."

Manufacturing Capability

         The manufacture of Lynx's products will be a time consuming and complex
process and will be subject to good manufacturing practice ("GMP") prescribed by
the FDA or other standards  prescribed by the appropriate  regulatory  agency in
the  country  of  use.  There  can be no  assurance  that  Lynx  will be able to
manufacture  products in a timely fashion, at acceptable quality and cost and in
sufficient quantities.

Absence of Sales and Marketing Experience; Product Liability Exposure and 
Insurance; Hazardous Materials

         Lynx has no  experience  in the sales,  marketing  or  distribution  of
pharmaceutical  products  and does  not  expect  to  establish  a  direct  sales
capability for at least several years.  To market any of its products  directly,
Lynx must  develop  a  substantial  sales and  marketing  force  with  technical
expertise and with supporting distribution capability. There can be no assurance
that Lynx  will  desire  to or be able to build  such a sales  force or that its
direct sales and marketing efforts will be successful.

         The use of any of Lynx's  products in  clinical  trials and the sale of
any products may expose Lynx to liability  claims resulting from the use of such
products.  These  claims  might  be made  directly  by  consumers,  

                                       6.
<PAGE>

health care providers, pharmaceutical companies or others selling such products.
Lynx intends to obtain product liability insurance coverage. No assurance can be
given that Lynx will be able to obtain such  insurance or, if  obtainable,  that
such  insurance can be acquired at reasonable  cost or in sufficient  amounts to
protect Lynx against losses that could have a material adverse effect on Lynx.

         Lynx's  research  and  development  may involve the  controlled  use of
hazardous materials,  chemicals,  viruses and various radioactive compounds.  In
the event of such an  accident,  Lynx could be held liable for any damages  that
result, and any liability could exceed the resources of Lynx.

Non-Corporate Collaborations/Sponsored Research

         Lynx's  R&D  strategy  has  been to  leverage  its  know-how  with  the
expertise  of  extramural  experts  active in a variety of disease  areas.  When
appropriate,  the Company has provided  financial support for its collaborators'
work  and,  in most  cases,  has  secured  the full  commercial  rights  for any
resulting drugs and targets.  The resulting research has thus drawn on resources
and skills far greater than the Company could have assembled  alone in its short
history and with its limited finances.  This strategy has allowed the Company to
defer investing in expensive  skills and  technologies  until it could ascertain
their relevance to specific product developments.

         Lynx has entered into a number of collaborations aimed at enhancing and
extending its research and development  activities.  The following describes the
Company's current academic collaborations:

         o A Sponsored  Research  Agreement with the Department of Neurosciences
of the Johns  Hopkins  University  Medical  Center is directed at the  molecular
characterization of genes induced in the brain by neural activation.

         o A Sponsored  Research  Agreement with Thomas Jefferson  University is
directed at in vivo mouse  experiments in CML and acute leukemias  utilizing the
Company's phosphoramidate ODNs. Basic research is also aimed at identifying mRNA
targets  that are  products of nuclear  proto-oncogenes  and  oncogenes,  and at
characterizing  receptor-mediated mechanisms associated with signal transduction
pathways in cancer.

         o A Sponsored Research  Agreement with the Thomas Jefferson  University
is directed at understanding the role of the IGF-1 receptor in protecting cancer
cells from dying. Phosphoramidate ODN anti-mRNA compounds targeting the receptor
are being optimized in vitro and in vivo.

         o A Sponsored  Research  Agreement with the  Interventional  Cardiology
Group at the Thomas  Jefferson  University  Medical Center is focused on in vivo
experiments using pigs to continue the exploration of the mechanism of action of
LR-3280,  and its possible  applicability  to  prevention  of restenosis in vein
grafts and related clinical indications.

         o A Sponsored Research Agreement with the Polish Academy of Sciences is
aimed at developing chiral phosphorothioate synthesis technology.

         o A Sponsored Research Agreement with the Hungarian Academy of Sciences
is aimed at the  development  of an  informatics  system  compatible  with  MPSS
analyses as well as the detailed analysis of novel genes identified at Lynx.

         o A Sponsored Research  Agreement with the Applied Biosystems  Division
of  Perkin  Elmer  Corporation  is aimed at the  application  of new  nucleotide
sequencing techniques to novel genes identified at Lynx.

         o  A   Sponsored   Research   Agreement  with  The  Molecular  Sciences
Institute is aimed at  conducting  feasibility  research on  Massively  Parallel
Genomic Sequencing ("MPGS"). 

                                       7.

Corporate Collaborations

         o In October 1996,  Lynx entered into two agreements with BASF AG aimed
at exploiting  Lynx's  proprietary MPSS technology.  The first agreement commits
the two  companies  to form a new  biotechnology  Joint  Venture  ("JV")  called
BASF-LYNX  Bioscience  AG in  Heidelberg,  Germany,  which will be governed by a
detailed  operating  agreement  developed  jointly between the Company and BASF.
Initial  ownership  of the JV  will be  split  51%-49%  between  BASF  and  Lynx
respectively.  Under  the  sponsorship  of BASF  and  Lynx  the JV will  seek to
identify novel drug targets in certain central nervous system diseases;  it will
attempt to determine whether the safety of chemicals can be correlated with, and
anticipated by, their effects on gene expression;  and, finally, it will seek to
optimize microorganisms used in the fermentation production of chemicals such as
vitamins or amino acids.  BASF will provide research funding of up to 50 million
DM (approximately  $33 million at current exchange rates) over the next 5 years,
as well as access to certain of its  technologies,  and Lynx will provide access
to its MPSS technology for use in the JV's research programs.

         The second  agreement  is a service  agreement  through  which BASF may
exploit the expected  power of Lynx's MPSS  technology  for its own internal and
proprietary  research,  independent of the JV's  objectives.  For access to this
service,  which  commits  Lynx to  provide  BASF with a  certain  number of MPSS
analyses  per year,  BASF  agreed to pay Lynx an access  fee of $5.5  million on
execution of the agreement, an additional fee of $5.5 million on the achievement
of a certain  milestone,  and a subscription fee of $8 million for the first two
years of the subscription agreement.

         o In September 1996,  Lynx entered into a collaboration  agreement with
Schwarz  Pharma AG to develop and market  Lynx's LR 3280 drug  candidate for the
European and North American  markets.  The agreement calls for Schwarz Pharma to
pay  Lynx  $4.0  million  and  $16.0  million  in  sign-up  and  milestone  fees
respectively,  and  for  Schwarz  Pharma  to  bear  the  costs  of  development,
regulatory approval and sales in the specified territories.  Schwarz Pharma will
also purchase the drug from Lynx, which retains all manufacturing rights.

         o In July 1996, Lynx entered into a collaboration agreement with Tanabe
Seiyaku Co.,  Ltd. to develop and market  Lynx's LR 3280 drug  candidate for the
Japanese and certain other Asian markets.  The agreement calls for Tanabe to pay
Lynx $3.5 million and $8.0 million in sign-up and milestone  fees  respectively,
and for Tanabe to bear the costs of development,  regulatory  approval and sales
in specified  territories.  Tanabe will also purchase the drug from Lynx,  which
retains all manufacturing rights.

         o In October 1995,  Lynx entered into an agreement  with Hoechst AG and
Hoechst Marion Roussel  (collectively  referred to as "Hoechst")  which provides
Hoechst access to Lynx's MPSS technology. Under the terms of the agreement, Lynx
received funds to accelerate  the  development  of its MPSS  technology  plus an
equity investment.  In return,  Lynx will clone and sequence cDNA libraries from
samples of interest to Hoechst. The agreement also stipulates that not more than
two  additional  companies  may  similarly  access  the  MPSS  technology  for a
specified period.  The combined equity,  R&D support payments,  and subscription
fees could reach $35 million by the end of 1998,  depending upon the achievement
of certain milestones and the quantity of samples submitted for analyses.

Research and Development Expenditures

         Lynx has devoted its efforts  primarily  to research  and  development.
Research and development expenses were $12.3 million for the year ended December
31, 1996,  $11.0  million for the year ended  December 31, 1995 and $7.7 million
for the year ended December 31, 1994.

         The Company is not a party to any material legal proceedings.


ITEM 4.           SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         On December 22, 1995, the Company commenced the solicitation of proxies
and written consents pursuant to Regulation 14 under the Securities Exchange Act
of 1934.  The  stockholders  of the  Company  voted by  written  consent  on the
following   proposal:   to  approve  an  amendment  to  the  Company's  Restated
Certificate  of  Incorporation  to effect a reverse stock split of the Company's
Common Stock and Preferred Stock, so that every ten shares of Common Stock would
be converted  into one share of Common Stock,  and every ten shares of Preferred
Stock would be converted into one share of the  appropriate  series of Preferred
Stock.  The  foregoing  proposal was  approved in January 1996 by the  Company's
stockholders.

         On October 7, 1996, the Company  commenced the  solicitation of proxies
and written consents pursuant to Regulation 14 under the Securities Exchange Act
of 1934. Only certain holders of record of Common Stock,  Series B, Series C and
Series  D  Preferred  Stock  of the  Company  voted by  written  consent  on the
following  proposal:  to approve  an  amendment  to the  Company's  Amended  and
Restated  Certificate of Incorporation  solely to decrease the authorized number
of shares of the Company's  Common Stock from  120,000,000  shares to 20,000,000
shares  and  the  authorized  number  of  the  Company's  Preferred  Stock  from
25,000,000 shares to 2,000,000 shares.  The decrease in the number of authorized

ITEM 7.          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                 RESULTS OF OPERATIONS


         Except for the historical  information  contained herein, the following
discussion   contains   forward-looking   statements   that  involve  risks  and
uncertainties.  The Company's actual results could differ  materially from those
discussed  here.  Factors  that could cause or  contribute  to such  differences
include,  but are not limited to, those discussed in this section, as well as in
the section entitled "Item 1 Business--Business Risks."

Overview

         Since its inception in July 1989 (as a division of Applied  Biosystems,
Inc. "ABI"),  Lynx  Therapeutics,  Inc.  ("Lynx") has devoted its efforts toward
research,  drug discovery and development  programs.  Lynx has been unprofitable
since its inception and expects to incur substantial losses for the next several
years, due primarily to the expansion of its research and development  programs,
including  development of its Massively Parallel Signature  Sequencing  ("MPSS")
and Massively Parallel Genomic Sequencing ("MPGS") technologies, phosphoramidate
chemistry and preclinical  studies and clinical trials. As of December 31, 1996,
Lynx's  accumulated  deficit was  approximately  $31.5 million (the  accumulated
deficit including Lynx's operations as a division of ABI as of December 31, 1996
was  approximately  $35.7  million).  Lynx may  generate  revenues  based on its
agreements  with  collaborative  partners  as a  result  of  achievement  of the
milestones  defined in the agreements.  However,  there is no guarantee that the
milestones will be achieved or that the technologies will be proven  successful.
Lynx does not anticipate that it will generate significant revenues and profits,
if any, from the commercial  sale of its products and services for several years
if not more. There can be no assurance that Lynx will ever successfully  develop
and market any of its proposed  products or that it will ever be able to achieve
or sustain profitability.

         Lynx's  business is subject to significant  risks,  including the risks
inherent in its research and development efforts,  uncertainties associated with
obtaining and enforcing patents,  the lengthy and expensive  regulatory approval
process,  and  possible  competition  from other  products.  The MPSS program is
dependent upon the successful integration of independent  technologies,  each of
which has its own development  risks. In addition,  Lynx's MPSS technology could
face  competition  from the  development  of  similarly  efficient,  or  better,
combinations of novel cloning and sequencing techniques. Further, even if Lynx's
products appear  promising at an early stage of development,  they may not reach
the market for a number of reasons.  Such reasons  include,  but are not limited
to, the  possibilities  that the  Company's  compounds  are found to be toxic or
ineffective during clinical trials, the failure to receive necessary  regulatory
approvals,  the  difficulty to  manufacture on a large scale or the inability to
market a compound due to proprietary rights of third parties.

Results of Operations

Years Ended December 31, 1996 and 1995

Revenue

         Lynx had total  revenues  of $9.7  million and  $680,000  for the years
ended December 31, 1996 and 1995, respectively.  The 1996 revenue  included $7.5
million  in  sign-up  fees  under the  Tanabe  and  Schwarz  Pharma  agreements;
approximately  $2.0  million  earned  under the  collaborative  agreements  with
Hoechst and BASF; and  approximately  $291,000 from a government grant. The 1995
revenue included  $375,000 of revenue earned under the  collaborative  agreement
with Hoechst and approximately  $305,000 generated from compound sales and grant
revenue.

Operating Expenses

         Costs of product  sales and other  revenues  were $291,000 for the year
ended  December 31, 1996,  compared to $265,000 for the year ended  December 31,
1995. The 1996 cost is related to activity under the government grant, while the
1995 cost is related both to grant activity and cost of compounds sold.

         Research and development expenses were $12.3 million for the year ended
December  31, 1996  compared to $11.0  million for the year ended  December  31,
1995.  The  increase  was due to expenses  associated  with the issuance of Lynx
Common Stock and stock options to certain employees and one consultant  pursuant
to the  Agreement  of Merger  between  Lynx and its  majority-owned  subsidiary,
Spectragen Inc.,  increased spending in support of clinical trials and increased
depreciation  on lab equipment used in research.  A portion of this increase was
offset by reduced funding to various  laboratories under collaborative  research
agreements and lower patent and related legal expense.  Lynx expects to continue
to incur substantial  research and development  expenses due to planned spending
for ongoing research activities and new research applications.

         General  and  administrative  expenses  were $3.2  million for the year
ended  December 31, 1996,  compared to $1.6 million for the year ended  December
31, 1995.  The increase was due  primarily to increased  legal fees,  investment
banking  fees,  and travel  expenses  incurred in  conjunction  with the Tanabe,
Schwarz-Pharma  and BASF  agreements  and to higher salary  expense  relating to
increased headcount and the settlement agreement associated with the termination
of a corporate  officer.  Lynx expects to continue to incur substantial  general
and administrative expenses in support of its research and corporate development
efforts.

Other

         Interest  income was  $585,000  for the year ended  December  31,  1996
compared to $744,000 for the year ended  December 31, 1995. The decrease was due
primarily to somewhat lower interest rates despite  slightly higher average cash
balances during the year ended December 31, 1996 as compared to the prior fiscal
year.

Income Taxes

         The provision for income taxes for the year ended  December 31, 1996 of
$10,000  consisted  entirely  of  alternative  minimum  tax.  There  was  no tax
provision for the year ended December 31, 1995.

Years Ended December 31, 1995 and 1994

Revenue

         Lynx had total  revenues of $680,000  for the year ended  December  31,
1995,  including  $375,000 of revenue earned under the  collaborative  agreement
with Hoechst.  In addition,  approximately  $305,000 was generated from compound
sales and grant revenue. This compared to total revenues of $4.7 million for the
year ended  December  31, 1994 which  consisted  of a $4.0  million  license fee
received  in  connection  with Lynx's  collaborative  research  and  development
agreement  with The  Wellcome  Foundation  Limited  ("Wellcome"),  approximately
$600,000  in  sales  of  compound   relating  to  the  Wellcome   agreement  and
approximately  $100,000 in grant  revenue.  During the year ended  December  31,
1995,  Wellcome and its parent company,  the Burroughs Wellcome Co., merged with
Glaxo plc and formed Glaxo Wellcome plc. Lynx was subsequently notified by Glaxo
Wellcome of its intention to terminate  Wellcome's agreement with Lynx effective
in March 1996.

Operating Expenses

         Costs of product  sales and other  revenue  were  $265,000 for the year
ended  December 31, 1995,  compared to $742,000 for the year ended  December 31,
1994. The decrease is due primarily to lower costs  associated  with lower sales
of compounds and grant revenue.

         Research and development expenses were $11.0 million for the year ended
December 31, 1995 compared to $7.7 million for the year ended December 31, 1994.
The increase was due primarily to higher  spending for  chemicals,  supplies and
prototype  materials,  increases  in  personnel,  expanded  funding  to  various
laboratories  under  collaborative  research  agreements  and higher  patent and
licensing expenses.

         General  and  administrative  expenses  were $1.6  million for the year
ended  December 31, 1995,  compared to $1.8 million for the year ended  December
31,  1994.  The  decrease in expenses  was due  primarily to a decrease in legal
services for corporate  general matters offset in part by increases in personnel
and increases in corporate development activities.

Other

         Interest  income was  $744,000  for the year ended  December  31, 1995,
compared to $506,000 for the year ended  December 31, 1994. The increase was due
primarily to higher  interest  rates during the year ended December 31, 1995, as
compared to the prior fiscal year.

Liquidity and Capital Resources

         Since inception,  Lynx has funded its operations  through advances from
ABI,  sales of  Preferred  and Common  Stock to venture  capital  investors  and
collaborative  partners,  revenues from  collaborative  research and development
arrangements,  interest income,  product sales and government  grants.  Lynx may
receive  additional  collaborative  research payments from BASF, Schwarz Pharma,
Tanabe  and  Hoechst,  and  equity  investments  from  Hoechst,  subject to Lynx
achieving the milestones as specified in the various agreements.

         Net cash provided in operating  activities of $1.3 million for the year
ended  December  31,  1996  differs  from the net loss for the same  period  for
several  reasons:  receipt of an access fee  related to the  collaboration  with
BASF,  the non-cash  expense  related to stock  issuance in the  Lynx/Spectragen
merger,  depreciation and amortization  expenses and changes in working capital.
Net cash  used in  investing  activities  of $3.1  million  for the  year  ended
December 31, 1996, was primarily due to the purchase of short-term  investments,
the expansion of facilities and capital equipment  purchases.  Net cash provided
by financing  activities  in 1996  consisted  primarily of the exercise of stock
options for cash by employees.  Cash and cash  equivalents were $12.1 million at
December 31, 1996.

         Lynx  is  currently   utilizing  its  available  funds  for  supporting
development of its MPSS technology,  funding  preclinical  research and clinical
trials and the planned growth in Lynx's internal efforts toward  research,  drug
discovery and development  programs.  Pending such uses as described above, Lynx
intends  to  invest   its  excess   cash  in   short-term,   investment   grade,
interest-bearing securities or certificates of deposit.

         The cost, timing and amount of funds required for specific uses by Lynx
cannot  be  precisely  determined  at this  time and will be based  upon  Lynx's
progress in its research and  development,  the scope and results of preclinical
research  and  clinical  trials,  the cost and timing of  regulatory  approvals,
administrative and legal costs, the establishment of corporate  partnerships and
the  availability  of alternate  methods of  financing.  Lynx  believes that its
current capital resources and interest income thereon will enable it to maintain
its  current  and planned  operations  through the end of 1997.  There can be no
assurance that any additional  financing  required by Lynx will be available or,
if available, will be on terms favorable to Lynx.

and sequencing  technologies,  collectively dubbed "massively parallel signature
sequencing"  ("MPSS")  which  is  being  developed  to be used to  identify  and
quantify,  in a single analysis, a complete  representative  sampling of all the
mRNA molecules present in a tissue sample. The rapidity (days, instead of months
or years) of this new analytical approach,  if successful,  should allow for the
first time the analysis of the changes in gene  expression that occur during the
progression of a disease.  Lynx's second set of proprietary  technologies  is an
outgrowth of the expertise on which Lynx was originally founded.  This expertise
relates to synthetic  DNA  ("oligodeoxynucleotide"  or "ODN")  chemistry and the
manufacture  and use of  synthetic  ODN  analogues  for  the  pursuit  of  their
therapeutic  applications.  Diseases that have been targeted for the application
of these potential therapeutic agents include cardiovascular  diseases,  cancers
and leukemias, and neurovascular diseases.

         In November 1996, Lynx and its majority owned  subsidiary,  Spectragen,
Inc.  ("Spectragen"),  a Delaware  corporation,  entered  into an  Agreement  of
Merger,   whereby  Lynx  acquired  the  outstanding  17%  minority  interest  in
Spectragen  and  Spectragen  was  merged  with  and into  Lynx and the  separate
corporate  existence  of  Spectragen  ceased  (the  "Merger").   Each  share  of
Spectragen Common Stock outstanding at the time of Merger was converted into 1.3
shares of Lynx  Common  Stock and all vested and  unvested  options to  purchase
shares of  Spectragen  Common  Stock  were  assumed by Lynx and  converted  into
options to purchase Lynx Common Stock at the same ratio.

         In February 1996, the Company filed an amendment to its  Certificate of
Incorporation  effecting a one-for-ten  reverse  stock split of all  outstanding
Common and Preferred  Stock,  warrants and options to purchase Common Stock. The
reverse stock split was approved by the majority of its  stockholders in January
1996.  All references to the number of shares and share prices  throughout  this
document reflect post-split activity.

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

         The Company has sustained  continuing operating losses and expects such
losses to continue for at least the next  several  years.  The Company  plans to
finance  operations  through equity  offerings to existing and new investors and
through  arrangements  with  corporate  partners.  Should  the  financing  plans
contemplated  by  management  not be  consummated,  the Company may have to seek
alternative sources of capital or reevaluate its operating plans.

Use of Estimates

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the amounts  reported in the financial  statements  and
accompanying notes. Actual results could differ from those estimates.

Cash, Cash Equivalents and Short-Term Investments

         The Company considers all investments with a remaining  maturity at the
date of  purchase  of 90 days or  less  as cash  equivalents.  Investments  with
remaining  maturities beyond 90 days but less than one year are considered to be
short-term  investments.  The Company's  investment  policy  stipulates that the
investment portfolio be maintained with the objectives of preserving  principal,
maintaining liquidity and maximizing return.

         The  Company   determines  the  appropriate   classification   of  debt
securities at the time of purchase and reevaluates  such  designation as of each
balance sheet date. As of December 31, 1996 and 1995, the Company has classified
its  entire  investment  portfolio  as  available-for-sale.   Available-for-sale
securities  are carried at fair value based on quoted  market  prices,  with the
unrealized  gains and losses reported as a separate  component of  stockholders'
equity.  The amortized cost of debt  securities in this category is adjusted for
amortization  of premiums and  accretion  of  discounts  to maturity,  which are
included in interest  income.  Realized  gains and losses and  declines in value
judged to be other-than-temporary on available-for-sale  securities are included
in  interest  income or  expense.  The cost of  securities  sold is based on the
specific identification method.

Property and Equipment

         Property and equipment are stated at original cost and are  depreciated
using the  straight-line  method over the estimated  useful lives of the assets,
which is generally three years.  Leasehold  improvements  are amortized over the
lessor of the useful  life of the asset or the  remaining  term of the  facility
lease.

Revenue Recognition

         Payments  under  collaborative  arrangements  are recognized as revenue
when earned as defined under the terms of the  respective  agreements.  Payments
received  which are related to future  performance  are deferred  until  earned.
Non-refundable  license fees are generally recorded as revenue upon execution of
the agreement. Revenues from the sales of products are recognized upon shipment.

         During 1996, revenue from three collaborative  partners represented 92%
of total revenue.  During 1995 and 1994, revenue from one collaborative  partner
represented 55% and 85% of total revenue, respectively.

Net Loss per Share

         Net loss per share is calculated  based on the weighted  average number
of common shares  outstanding  during the period.  Common equivalent shares from
stock options,  warrants and  convertible  Preferred Stock are excluded from the
computation as their effect is antidilutive.

Stock-Based Compensation

         As permitted by Statements of Financial  Accounting  Standards No. 123,
"Accounting for Stock-Based  Compensation" ("SFAS 123"), the Company has elected
to account for stock  options  granted to employees  using the  intrinsic  value
method and,  accordingly,  does not recognize  compensation  expense for options
granted to employees with exercise  prices equal to the fair market value of the
Company's Common Stock.

</TABLE>


         During the years ended  December 31, 1996 and 1995, the Company did not
sell any  securities.  As of December 31, 1996,  $11.9 million of the marketable
securities were classified as cash equivalents,  and the balance of $2.0 million
was  classified  as  short-term  investments.  As  of  December  31,  1995,  all
marketable  securities were classified as cash equivalents.  Expected maturities
may differ from contractual maturities because the issuers of the securities may
have the right to prepay obligations without prepayment penalties.

3.       Collaborative Arrangements

         In October 1996, Lynx entered into two agreements with BASF AG aimed at
exploiting Lynx's  proprietary MPSS technology.  The first agreement commits the
two companies to form a new biotechnology  Joint Venture ("JV") called BASF-LYNX
Bioscience AG in Heidelberg,  Germany. Initial ownership of the JV will be split
51%-49%  between BASF and Lynx  respectively.  Under the sponsorship of BASF and
Lynx the JV will seek to identify novel drug targets in certain  central nervous
system  diseases;  it will attempt to determine  whether the safety of chemicals
can be correlated  with, and  anticipated  by, their effects on gene  expression
and, finally,  it will seek to optimize  microorganisms used in the fermentation
production  of  chemicals  such as vitamins or amino  acids.  BASF will  provide
research  funding of up to 50 Million DM  (approximately  $33 million at current
exchange  rates) over the next five  years,  as well as access to certain of its
technologies, and Lynx will provide access to its MPSS technology for use in the
JV's research programs.

         The second  agreement  is a service  agreement  through  which BASF may
exploit the expected  power of Lynx's MPSS for its own internal and  proprietary
research,  independently  of the JV's  objectives.  For access to this  service,
which  commits Lynx to provide BASF with a certain  number of MPSS  analyses per
year,  BASF agreed to pay Lynx an access fee of $5.5 million  upon  execution of
the  agreement,  of which  $458,000 was  recognized as revenue in the year ended
December 31, 1996. BASF will pay an additional access fee of $5.5 million on the
achievement of a certain  milestone and a subscription fee of $8 million for the
first two years of the subscription agreement.

3.       Collaborative Arrangements  (continued)

         In September  1996,  Lynx entered into a  collaboration  agreement with
Schwarz  Pharma AG to develop and market  Lynx's LR 3280 drug  candidate for the
European and North American  markets.  The agreement calls for Schwarz Pharma to
pay Lynx certain  sign-up and milestone fees, and for Schwarz Pharma to bear the
costs  of   development,   regulatory   approval  and  sales  in  the  specified
territories. Schwarz Pharma will also purchase the drug from Lynx, which retains
all manufacturing rights.

         In July 1996, Lynx entered into a  collaboration  agreement with Tanabe
Seiyaku Co.,  Ltd. to develop and market  Lynx's LR 3280 drug  candidate for the
Japanese and certain other Asian markets. The agreements calls for Tanabe to pay
Lynx  certain  sign-up  and  milestone  fees and for Tanabe to bear the costs of
development,  regulatory approval and sales in the specified territories. Tanabe
will also purchase the drug from Lynx, which retains all manufacturing rights.

         In July and October  1996,  Lynx  received the sign-up fees of $3.5 and
$4.0 million from the agreements with Tanabe and Schwarz  Pharma,  respectively.
These  payments  were  recorded as revenue in the period  received.  The Company
could  receive an  additional  $24.0  million in the form of milestone  payments
under the agreements.

         In October  1995,  Lynx entered  into an agreement  with Hoechst AG and
Hoechst Marion Roussel (collectively  referred to as "Hoechst"),  which provides
Hoechst with access to Lynx's MPSS technology. Under the terms of the agreement,
Lynx will receive funding to accelerate the development of its MPSS  technology,
and in  return,  it will  clone and  sequence  cDNA  libraries  from  samples of
interest  to Hoechst as soon as the  technology  is  reduced to  practice.  This
agreement  allows  for no more than two  additional  companies  to  access  this
technology for a specified period.

         In October 1995,  Lynx received  $3.0 million in  development  payments
from Hoechst,  of which $1.5 million and $375,000 were recognized as revenue for
the years ended  December  31, 1996 and 1995,  respectively.  In  addition,  the
Company  received  $5.0  million in November  1995  relating to the closing of a
private  placement  offering to Hoechst  40,000 shares of its Series D Preferred
Stock at $125.00 per share.  The Company could receive up to an additional $27.0
million through the end of 1998 in the form of milestone payments,  subscription
fees and additional equity investments.

4.       License Agreements

University of Nebraska

         In June 1992,  Lynx entered into an agreement  with the  University  of
Nebraska  under  which the  University  agreed to fund most  aspects  of certain
clinical  trials and grant licenses to certain  technology to Lynx. In exchange,
Lynx issued 10,000 shares of its Common  Stock,  and an additional  5,000 shares
upon  achievement of a clinical  trial  milestone by the  University.  The costs
associated  with the issuance of the Common Stock were  included in research and
development expense and are recorded at its deemed fair market value at the date
of issuance. In January 1996, this agreement was terminated.

                                      26.

Other

         Lynx or its  predecessor,  ABI, has entered into various  other license
agreements  with other  companies  and academic  institutions.  Such  agreements
generally  require  Lynx  to pay  annual  or  semiannual  license  fees  and are
generally cancelable upon 60 to 120 days' notice.

5.      Transaction with Related Parties

        Hoechst  AG  and  Hoechst  Marion  Roussel.  See  Note  3. Collaborative
        Arrangements

Notes Receivable from Officers

         In May and June 1995,  the Company  entered  into three  separate  loan
agreements  with an officer of the  Company.  The first loan of  $450,000  was a
promissory note secured by a second mortgage on real property. The principal and
interest  on this  loan  were  repaid  according  to the  terms  of the  note in
September  1996,  upon sale of the  property.  The second loan of  $450,000  was
issued under a stock  purchase  agreement for the purchase of 250,000  shares of
Common Stock whereby all the shares  issued under the agreement  were pledged as
collateral.  Of the 250,000 shares, 225,000 shares were subject to the Company's
right of repurchase  which lapsed  ratably over five years.  The loan  agreement
specified  that upon  termination,  after the Company's  right of repurchase was
exercised,  the  remaining  principal  and  interest  on the  loan  were due and
payable.  In November  1996, the officer left the Company and the stock purchase
loan was repaid in full. The third loan was a line of credit  agreement  whereby
the officer  could  borrow from the Company up to $25,000 per  calendar  quarter
during the first two years of employment.  The line was secured by shares of the
Company's stock owned by the officer.  The principal and accrued interest due on
the line of credit,  an aggregate of $157,862,  was forgiven  upon the officer's
separation from the Company.

         In October 1995, the Company entered into a loan agreement with another
officer of the Company. The note receivable of $210,000 was issued under a stock
purchase agreement for the purchase of 60,000 shares of Common Stock whereby all
the shares issued under the agreement are pledged as collateral. The outstanding
principal  amount is due and  payable in full on October 1, 2000,  subject to an
obligation to prepay under specified circumstances. Interest is payable upon the
expiration  or  termination  of the note and  accrues  at the rate of 6.38%  per
annum.

6.       Stockholders' Equity

Preferred Stock

         Each  share of  Series  B,  Series C and  Series D  Preferred  Stock is
convertible into ten shares of Common Stock at the option of the holder (subject
to adjustment for certain changes in the effective conversion price). The Series
B, Series C and Series D preferred shares have voting rights equal to the voting
rights of the common shares  issuable upon  conversion.  Conversion is automatic
upon the earlier of (i) the closing of an underwritten public offering of Common
Stock under the  Securities  Act of 1933 in which the Company  receives at least
$15,000,000 in gross proceeds and a price per share of at least $15.00 per share
(subject to adjustment for stock splits or similar events),  or (ii) the vote or
written consent of the holders of a majority of the outstanding Series B, Series
C and Series D  convertible  Preferred  Stock.  Series B,  Series C and Series D
stockholders  are  entitled to receive  noncumulative  dividends,  amounts to be
determined  if and when  declared by the Board of  Directors.  In  addition,  no
dividend  other than a stock  dividend  shall be paid on Common  Stock  unless a
dividend  in an equal  amount per share  (based on the  then-current  conversion
rate) is  first  declared  and  paid on the  Series  B,  Series  C and  Series D
Preferred  Stock. In the event of liquidation,  holders of Series B and Series C
Preferred  Stock  shall be  entitled  to receive  an amount  equal to $50.00 per
share, and Series D Preferred Stock, $125.00 per share (all of which are subject
to adjustment),  plus all declared but unpaid  dividends before any payments are
made to holders of Common Stock.

6.       Stockholders' Equity  (continued)

Common Stock

         In 1992,  Lynx issued  approximately  140,000 shares of Common Stock to
certain employees of and consultants to the Company. These shares are subject to
repurchase  rights which expire ratably over a five-year period from the date of
issuance.  Lynx has recorded  deferred  compensation  expense for the difference
between the  purchase  price and the deemed value of certain of these shares for
financial statement purposes.  At December 31, 1996,  approximately 5,083 shares
were subject to repurchase at $0.10 per share.

         In November  1996,  Lynx issued  959,182 shares of Lynx Common Stock to
certain officers, employees and one consultant in exchange for 737,832 shares of
Spectragen,  Inc.  Common Stock  pursuant to Merger  between Lynx and Spectragen
(See  "Note 1 of Notes to  Financial  Statements").  A portion of the shares are
subject to repurchase  rights which expire ratably  through 2006.  Lynx recorded
compensation  and consultant  expense of $2.0 million and deferred  compensation
expense of $1.4 million for the difference  between the fair market value of the
Lynx stock and the deemed fair market value of the  Spectragen  stock on the day
of acquisition.

         At December 31, 1996,  Lynx has  reserved  10,652,862  shares of Common
Stock for  issuance  upon  conversion  of the  Series B,  Series C and  Series D
Preferred  Stock,  upon the achievement of certain  established  milestones by a
research  collaborator  and  upon  the  exercise  of  outstanding  employee  and
nonemployee stock options.

1992 Stock Option Plan

         In July 1992,  Lynx  adopted the 1992 Stock  Option  Plan ("the  Plan")
under which incentive or nonqualified stock options to purchase shares of Common
Stock may be granted to  employees  and  officers  of, and  consultants  to, the
Company.  In January 1995 and May 1996, the stockholders  approved amendments to
the 1992 Plan to  increase  the  number  of  shares  reserved  for  issuance  to
1,400,000 and 2,100,000, respectively. The number of shares available for option
grants has been reduced by the 140,000  shares of Common Stock which were issued
to certain employees and consultants, as discussed above.

         Under the Plan, the exercise price of incentive options granted may not
be less than 100% (110% in the case of options granted to a person who owns more
than 10% of the  total  combined  voting  power of all  classes  of stock of the
Company)  of the fair  market  value  of  Common  Stock  at the  date of  grant.
Nonqualified options may be granted at not less than 85% of fair market value at
the date of grant.  Options generally vest over a five-year period from the date
of grant and have a term of ten years (five years in the case of options granted
to a person  who owns more than 10% of the total  combined  voting  power of all
classes of stock of the Company).

         In November 1996,  Lynx issued 524,355  options to purchase Lynx Common
Stock in  exchange  for  403,350  options to purchase  Spectragen  Common  Stock
pursuant to the  Agreement  of Merger  between the  Company and  Spectragen.  In
accordance  with  APB  25,  Accounting  for  Stock  Issued  to  Employees,  Lynx
recognized  compensation  costs  and  deferred  compensation   representing  the
difference  between the exercise  price of the options and the fair market value
of the  Company's  Common Stock on the day of the grants.  The Company  recorded
approximately  $29,000 as  compensation  expense for the year ended December 31,
1996,  for the portion of the options that had vested  during  fiscal year 1996,
and  deferred  compensation  of  approximately  $683,000  for the portion of the
grants  that will vest in future  periods.  The  deferred  compensation  will be
charged to expense over the vesting period of the grants.

Pro Forma Information

         The Company has elected to follow APB 25 and related interpretations in
accounting for its stock options  because,  as discussed  below, the alternative
fair  value  accounting  provided  for  under  SFAS 123  requires  use of option
valuation models that were not developed for use in valuing stock options. Under
APB 25, when the exercise price of the Company's stock options equals the market
price of the underlying stock on the date of the grant, no compensation  expense
is recognized.

         Pro  forma  information  regarding  net loss and net loss per  share is
required by SFAS 123, and has been  determined  as if the Company had  accounted
for its stock  options  granted  subsequent  to December 31, 1994 under the fair
value method of SFAS 123. The fair value for these  options was estimated at the
date of grant using a Black-Scholes option pricing model for the multiple option
approach with the following  weighted-average  assumptions: a risk-free interest
rate of 6.26%  and  6.36%  for 1995 and 1996  respectively,  a  weighted-average
expected  life of 4.4 years for 1995  grants and 4.1 years for 1996  grants;  an
expected dividend yield of zero for both years. The Company believes that due to
the low  trading  volume of Lynx stock,  particularly  in 1995,  the  calculated
volatility of the expected  market price of the Company's  Common Stock does not
provide a representative picture of future volatility. Consequently, an industry
average volatility of 73% was used in the calculations.

         The  Black-Scholes  option  valuation  model was  developed  for use in
estimating the fair value of traded  options which have no vesting  restrictions
and are fully  transferable.  In addition,  option  valuation models require the
input of highly  subjective  assumptions  including  the  expected  stock  price
volatility.   Because  the   Company's   stock   options  have   characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially  affect the fair value estimate,  in
management's  opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of the Company's stock options.

6.       Stockholders' Equity  (continued)


         For purposes of pro forma disclosures,  the estimated fair value of the
options is amortized to pro forma net loss over the options' vesting period. The
Company's historical and pro forma information follows (in thousands, except for
net loss per share information):

         Because SFAS 123 is applicable  only to options  granted  subsequent to
December  31,  1994,  future pro forma net income and  earnings/loss,  per share
results may be materially different from actual amounts presented.

Warrants

         As of December  31, 1996,  warrants to purchase  6,300 shares of Common
Stock were  outstanding at an exercise  price of $12.50 per share.  The warrants
expired on February 14, 1997.

7.       Income Taxes

         The Company  accounts  for income taxes under the  Statement  Financial
Accounting  Standards  No. 109,  "Accounting  for Income  Taxes."  Lynx's losses
through November 20, 1992 were included in the  consolidated  income tax returns
of ABI or ABI's  parent  (Perkin  Elmer  Corporation).  As a result,  Lynx's net
operating loss  carryforwards  available to offset future taxable income consist
only of losses incurred after November 20, 1992.

         The  provision  for  income  taxes for 1996 in the  amount  of  $10,000
consists entirely of alternative minimum tax.

         As of  December  31,  1996,  the  Company  has  federal  and state loss
carryforwards of approximately $20.3 million and $1.2 million, respectively. The
Company  also  has  federal  and  state  research  and  development  tax  credit
carryforwards of approximately $634,000 and $297,000,  respectively. The federal
net  operating  loss and federal and state credit  carryforwards  will expire at
various dates  beginning in the years 2007 through  2010,  if not utilized.  The
state net operating loss will expire in 2000, if not utilized.

         Utilization of the net operating losses and credits may be subject to a
substantial annual limitation due to the ownership change  limitations  provided
by the Internal  Revenue Code of 1986 and similar state  provisions.  The annual
limitation  may result in the  expiration  of net  operating  losses and credits
before utilization.

         The  federal  net  operating   loss   carryforwards   differ  from  the
accumulated  deficit  principally due to losses incurred while the Company was a
division of ABI, and timing  differences in the  recognition of certain  expense
items for financial and federal tax reporting purposes,  consisting primarily of
certain  accrued  expenses  that are not  currently  deductible  for  income tax
purposes.

         Deferred income taxes reflect the tax effects of net operating loss and
credit  carryforwards and of temporary  differences between the carrying amounts
of assets and liabilities for financial reporting and the amount used for income
tax purposes.

8.       Obligations under Operating Leases

         The Company entered into a noncancelable operating lease for facilities
which commenced on August 1, 1993 and expires on July 31, 2003.  Under the terms
of the lease,  rental  payments  commenced  in the third  month of the lease and
increase on a graduated scale beginning with the second year of the lease as the
Company occupies  additional space. The Company is recognizing rent expense on a
straight-line method over the lease period. The Company has the option to extend
the lease for two  additional  periods of five years each,  with  payments to be
determined when the option is exercised. The Company also leases equipment under
various operating lease agreements subject to minimum annual lease payments.

         Minimum  annual  rental  commitments  under  operating  leases  are  as
follows:

9.       401(k) Plan

         In  October  1992,  Lynx  adopted  a 401(k)  Plan  covering  all of its
employees.  The 401(k) Plan is intended to qualify under Section 401 of the Code
so that contributions by employees or by Lynx to the 401(k) Plan are not taxable
to employees until withdrawn from the 401(k) Plan, and so that  contributions by
Lynx, if any, will be deductible by Lynx when made. Pursuant to the 401(k) Plan,
employees may elect to reduce their current  compensation  by up to 15% (subject
to an annual  limit  prescribed  by the Code as  described  below)  and have the
amount of such  reduction  contributed  to the 401(k)  Plan.  Under  limitations
imposed by the Code, the maximum amount of compensation  reduction a participant
could elect to have  contributed  to the 401(k) Plan for the 1996  calendar year
was $9,500.  This amount is subject to annual  adjustments  for increases in the
cost of living,  as determined under Internal Revenue Service  regulations.  The
401(k) Plan  permits,  but does not  require,  additional  contributions  to the
401(k) Plan by Lynx on behalf of all participants in the 401(k) Plan.

         Except as disclosed  above, no compensation  characterized as long-term
compensation,  including  restricted  stock awards  issued at a price below fair
market  value or  long-term  incentive  plan  payouts,  were paid by the Company
during the year ended December 31, 1996, to any of the Named Executive Officers.

1992 Stock Option Plan

         In June  1992,  Lynx  adopted  the 1992  Stock  Option  Plan (the "1992
Plan"),  under which  400,000  shares,  less any shares of Lynx's  Common  Stock
remaining outstanding which were originally issued to employees, officers of, or
consultants  to Lynx pursuant to Stock  Purchase  Agreements  approved by Lynx's
Board of  Directors,  were  initially  reserved  for issuance  upon  exercise of
options  granted to employees  and  consultants  of Lynx or its  affiliates.  In
January 1995 and May 1996, the stockholders approved amendments to the 1992 Plan
to  increase  the  number of shares  reserved  for  issuance  to  1,400,000  and
2,100,000, respectively In May 1996, the stockholders also approved an amendment
to the 1992 Plan to  extend  the term of the Plan to March  2006.  The 1992 Plan
provides for the grant of both  incentive  stock options  intended to qualify as
such under  Section 422 of the  Internal  Revenue  Code of 1986 (the "Code") and
nonstatutory  stock options,  which are options that do not qualify as incentive
stock options.

         In November  1996,  pursuant  to the  Agreement  of Merger  between the
Company and Spectragen,  options to purchase 403,350 shares of Spectragen Common
Stock were assumed by the Company and converted into options to purchase 524,355
shares of Lynx Common Stock.

         The 1992 Plan is administered by the Board of Directors. Subject to the
provision of the 1992 Plan, the Board has the authority to select the persons to
whom grants are to be made,  to designate  the number of shares to be covered by
each option,  to determine  whether an option is an incentive  stock option or a
nonstatutory stock option, to establish vesting  schedules,  to specify the type
of  consideration  to be paid to Lynx upon exercise or purchase and,  subject to
certain restrictions, to specify other terms.

         The maximum term of options  granted  under the 1992 Plan is ten years.
The  aggregate  fair market value of the stock with  respect to which  incentive
stock  options  are  first  exercisable  in any  calendar  year  may not  exceed
$100,000. Options granted under the 1992 Plan generally are non-transferable and
expire  three  months  after  the  termination  of  any  optionee's  employment,
directorship or consulting  relationship with Lynx. However, in general, if such
termination  of  employment  is  due  to  the  optionee's  permanent  and  total
disability,  such person's option may be exercised up to one year following such
disability,  and if such  termination  of  employment  is due to the  optionee's
death,  such  person's  option  may be  exercised  up to  eighteen  (18)  months
following death.

         The exercise price of incentive stock options must be at least the fair
market  value of the Common Stock on the date of grant.  The  exercise  price of
nonstatutory  stock options must be at least 85% of the fair market value of the
Common Stock on the date of grant.  The exercise price of options granted to any
person who at the time of grant owns stock possessing more than 10% of the total
combined  voting power of all classes of stock must be at least 110% of the fair
market value of such stock on the date of grant,  and the term of these  options
cannot exceed five years. Shares covered by currently  outstanding options under
the 1992 Plan  typically  vest over a  five-year  period  following  the date of
grant.

(1)      Officers of the Company were granted the right to exercise their options prior to vesting,  subject to the Company's right
         of repurchase at the original issue price,  which lapses ratably over five years.  Options granted generally vest over a
         five-year period.  The term of the options is ten years.

(2)      Based on an aggregate of 859,858 options granted to employees of and consultants to the Company during the year ended 
         December 31, 1996, including the Named Executive Officers.

(3)      The exercise price per share of each option is equal to the fair market value as determined by the Board of Directors, 
         except for the grants pursuant to the Merger,  the exercise price is the original Spectragen grant price, as adjusted 
         pursuant to the terms of the Agreement of Merger.

(4)      The potential  realizable  value is calculated based on the term of the option at its time of grant (ten years).  It is
         calculated by assuming that the fair market value of the stock as determined by the Board of Directors on the date of grant
         appreciated  at the  indicated  annual rate  compounded  annually  for the entire term of the option and that the option is
         exercised and sold on the last day of its term for the appreciated  stock price.  These amounts  represent  certain assumed
         rates of  appreciation  only,  in  accordance  with the rules of the SEC,  and do not  reflect  the  Company's  estimate or
         projection of future stock price  performance.  Actual gains, if any, are dependent on the actual future performance of the
         Company's Common Stock and no gain to the optionee is possible unless the stock price increases over the option term, which
         will benefit all stockholders.

(5)      Dr. Martin's shares were canceled in November 1996 due to the termination of his relationship with the Company.

Compensation of Directors

         Directors are not compensated by the Company for service as directors.

Compensation Committee Interlocks and Insider Participation

         The Company's  Compensation  Committee was  established  in March 1994.
There  were  no  officers  or  employees  of the  Company  who  participated  in
deliberations  of the  Company's  Compensation  Committee  concerning  executive
officer compensation during the year ended December 31, 1996.

Limitations of Liability and Indemnification

         The  Company's  Bylaws  provide  that the Company  will  indemnify  its
directors and executive officers and may indemnify its other officers, employees
and other agents to the fullest extent permitted by Delaware law. The Company is
also empowered  under its Bylaws to enter into  indemnification  agreements with
its  directors  and officers  and to purchase  insurance on behalf of any person
whom it is required or permitted to 


                                       39.
<PAGE>

indemnify.  Pursuant to this  provision,  the Company has entered into indemnity
agreements with each of its directors and executive officers.

         In addition,  the Company's Certificate of Incorporation provides that,
to the fullest  extent  permitted by Delaware law, the Company's  directors will
not be liable for monetary  damages for breach of the directors'  fiduciary duty
of care to the Company and its  stockholders.  This provision in the Certificate
of  Incorporation  does  not  eliminate  the duty of  care,  and in  appropriate
circumstances,  equitable  remedies  such as an  injunction  or  other  forms of
nonmonetary relief would remain available under Delaware law. Each director will
continue to be subject to liability for breach of the director's duty of loyalty
to the Company, for acts or omissions not in good faith or involving intentional
misconduct or knowing violations of law, for acts or omissions that the director
believes  to  be  contrary  to  the  best   interests  of  the  Company  or  its
stockholders,  for any transaction  from which the director  derived an improper
personal benefit,  for acts or omissions  involving a reckless disregard for the
director's duty to the Company or its  stockholders  when the director was aware
or should  have been  aware of a risk of  serious  injury to the  Company or its
stockholders,  for acts or omissions  that  constitute  an unexcused  pattern of
inattention  that amounts to an abdication of the director's duty to the Company
or its  stockholders,  for  improper  transactions  between the director and the
Company and for improper  distributions  to stockholders  and loans to directors
and officers. This provision also does not affect a director's  responsibilities
under any other  laws such as the  federal  securities  laws or state or federal
environmental laws.

         No pending  material  litigation  or  proceeding  involving a director,
officer,  employee or other agent of the Company as to which  indemnification is
being sought  exists,  and the Company is not aware of any pending or threatened
material  litigation  that may  result  in  claims  for  indemnification  by any
director, officer, employee or other agent.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Corporate  Collaborations

         See Item 1. Business and Note 3. of the Notes to Consolidated Financial
Statements.

         In 1992, ABI  distributed all but an aggregate of 299,800 shares of the
Lynx  Common  Stock  it  held  to  its  shareholders  (the  "Distribution").  In
connection with this  transaction,  Lynx granted ABI an option to purchase up to
215,900  shares of Lynx Common Stock at $0.10 per share which,  prior to October
1996, may only be exercised by ABI in connection with the distribution by ABI of
Lynx  stock  to its  option  holders  upon the  exercise  of ABI  stock  options
outstanding  as of  the  date  of  the  Distribution.  Thereafter,  through  the
termination  of the option in  September  1997,  ABI may  exercise  such  option
provided  that it promptly  sells or otherwise  disposes of any shares  received
upon such exercise.  At December 31, 1996,  there were 152,400 shares  available
for exercise.

Transactions with Directors and Executive Officers

         In November 1996, Lynx and its majority owned  subsidiary,  Spectragen,
Inc. ("Spectragen"), a Delaware corporation, entered into an Agreement of Merger
pursuant  to which  Spectragen  was merged  with and into Lynx and the  separate
corporate  existence  of  Spectragen  ceased  (the  "Merger").   Each  share  of
Spectragen Common Stock outstanding at the time of Merger was converted into 1.3
shares of Lynx  Common  Stock and all vested and  unvested  options to  purchase
shares of  Spectragen  Common  Stock  were  assumed by Lynx and  converted  into
options to purchase  Lynx Common Stock at the same ratio.  Dr.  Eletr,  a former
stockholder  and  optionholder  of Spectragen,  received  130,000 shares of Lynx
Common Stock and an option to purchase  32,500  shares of Lynx Common Stock as a
result of the merger.  Dr. Brenner,  a former  stockholder  and  optionholder of
Spectragen,  received  260,000  shares  of Lynx  Common  Stock  and an option to
purchase 65,000 shares of Lynx Common Stock as a result of the merger.

         In May and June 1995,  the Company  entered  into three  separate  loan
agreements  with  David  W.  Martin,  Jr.,  M.D.,  who was  then  the  Company's
President.  The first loan of $450,000 was a promissory note secured by a second
mortgage on real  property.  The principal and interest on this loan were repaid
according to the terms of the note in September 1996, upon sale of the property.
The second loan of $450,000 was issued under a Stock Purchase  Agreement for the
purchase of 250,000  shares of Common Stock  whereby all the shares issued under
the agreement were pledged as collateral.  Of the 250,000 shares, 225,000 shares
were subject to the Company's right of repurchase which lapsed ratably over five
years. The loan agreement  specified that upon termination,  after the Company's
right of repurchase was exercised,  the remaining  principal and interest on the
loan were due and payable.  In November  1996,  the officer left the Company and
the stock  purchase loan was repaid in full. The third loan was a line of credit
agreement  whereby Dr.  Martin  could  borrow from the Company up to $25,000 per
calendar quarter during the first two years of employment.  The line was secured
by shares of the Company's  Common Stock owned by Dr. Martin.  The principal and
accrued  interest  due on the line of credit,  an  aggregate  of  $157,862,  was
forgiven upon Dr. Martin's separation from the Company.

         In October 1995, the Company entered into a loan agreement with another
officer of the Company. The note receivable of $210,000 was issued under a Stock
Purchase Agreement for the purchase of 60,000 shares of Common Stock whereby all
the shares issued under the agreement are pledged as collateral. The outstanding
principal  amount is due and  payable in full on October 1, 2000,  subject to an
obligation to prepay under specified circumstances. Interest is payable upon the
expiration  or  termination  of the note and  accrues  at the rate of 

                                      44.
<PAGE>

6.38% per annum. As of February 28, 1997, the outstanding  principal and accrued
interest under the note was $228,906.

         The Company currently has no other employment  contracts with any Named
Executive  Officers,   and  the  Company  has  no  other  compensatory  plan  or
arrangement  with Named  Executive  Officers where the amounts to be paid exceed
$100,000 and which are activated upon resignation,  termination or retirement of
any such executive officer or upon a change in control of the Company.

         For legal services rendered during the calendar year ended December 31,
1996,  the Company  paid  approximately  $468,937  to Cooley  Godward  LLP,  the
Company's counsel, of which Mr. Kitch, a director of the Company, is a partner.

         FIRST:  The name of the  corporation  is Lynx  Therapeutics,  Inc. (the

                  A. This  Corporation  is  authorized  to issue two  classes of
         shares to be  designated,  respectively,  "Common Stock" and "Preferred
         Stock." The total number of shares which the  Corporation is authorized
         to issue is Twenty-two  Million  (22,000,000)  shares.  Twenty  Million
         (20,000,000)  shares shall be Common  Stock,  par value one cent ($.01)
         per share (the "Common Stock") and Two Million (2,000,000) shares shall
         be Preferred Stock, par value one cent ($.01) per share (the "Preferred
         Stock")."

                  B. The shares of  Preferred  Stock may be issued  from time to
         time in one or more series.  The Board of Directors of the  corporation
         is expressly  authorized  to provide for the issue of all or any of the
         shares of Preferred Stock in one or more series,  and to fix the number
         of shares and to determine  or alter for each such series,  such voting

         constituting  such decrease shall resume the status that they had prior
         to the  adoption  of the  resolution  originally  fixing  the number of
         shares of such series.

                                       2.



                                                                   EXHIBIT 10.25

                            STOCK PURCHASE AGREEMENT


         THIS STOCK PURCHASE AGREEMENT is made by and between SPECTRAGEN,  INC.,
a Delaware corporation (the "Company"), and SAM ELETR ("Purchaser").

                                   WITNESSETH:

         WHEREAS,  Purchaser  holds a  non-statutory  stock  option to  purchase
shares of common  stock of the  Company  pursuant  to the  Company's  1995 Stock
Option Plan (the "Plan") which Purchaser desires to exercise; and

         WHEREAS,  Purchaser  wishes to take  advantage  of the  early  exercise
provision of his option and therefore to enter into this Agreement;

         NOW, THEREFORE, IT IS AGREED between the parties as follows:

         1.  Purchaser  hereby  agrees to  purchase  from the  Company,  and the
Company hereby agrees to sell to Purchaser, an aggregate of One Hundred Thousand
(100,000)  shares of the Company's  Common Stock (the "Stock"),  for an exercise
price of Twenty Cents ($0.20) per share (total exercise price:  (Twenty Thousand
Dollars ($20,000)), payable in cash.

         The closing  hereunder shall occur at the offices of the Company on the
date of this  Agreement  or at such  other  time and  place as the  parties  may
mutually agree upon in writing.

         At the closing, Purchaser shall deliver one (1) stock assignment in the
form of Exhibit A, duly  endorsed  (with date and number of shares left  blank),
joint  escrow  instructions  (the "Joint  Escrow  Instructions")  in the form of
Exhibit B, duly executed by Purchaser, and the total exercise price.

         At the closing or as soon thereafter as practicable,  the Company shall
deliver  to the  Escrow  Agent  (as  defined  in  paragraph  8  below)  a  share
certificate  for all of the Stock that is to be subject to the  Purchase  Option
(as defined in paragraph 2 below).

         2.  In  accordance  with  the  provisions  of  Section  408(b)  of  the
California  General  Corporation  Law,  the Stock to be  purchased  by Purchaser
pursuant to this Agreement shall be subject to the following  option  ("Purchase
Option"):

                  (a) In the event that Purchaser  shall cease to be an employee
of the  Company for any reason  (including  his  death),  or no reason,  with or
without cause, the Purchase Option may be exercised.  The Company shall have the
right  at  any  time  within  the  ninety  (90)  day  period  after  Purchaser's
termination of service with the Company and all related companies or such longer
period as may be agreed to by the Company and

<PAGE>


Purchaser (for example,  for purposes of satisfying the  requirements of Section
1202(c)(3)  of the  Internal  Revenue  Code) to purchase  from  Purchaser or his
personal  representative,  as the case may be, at the  price  per share  paid by
Purchaser pursuant to this Agreement ("Option Price").

                  (b) The Stock shall vest as follows:  One-twentieth  (1/20) of
the total  number of shares of Stock  shall vest one year from the first date of
employment and one-sixtieth  (1/60) will vest monthly  thereafter,  so that upon
the date that is five years  from the  Commencement  Date,  all of the shares of
Stock shall have  vested.  Shares of Stock that have vested shall not be subject
to the Purchase Option.

                  (c) In addition,  and without limiting the foregoing  Purchase
Option, if at any time during the term of the Purchase Option, there occurs: (a)
a  dissolution  or  liquidation  of the Company;  (b) a merger or  consolidation
involving the Company in which the Company is not the surviving  Company;  (c) a
reverse merger in which the Company is the surviving  corporation but the shares
of the Company's common stock outstanding  immediately  preceding the merger are
converted  by virtue of the merger into other  property,  whether in the form of
other securities,  cash or otherwise; or (d) any other capital reorganization in
which more than fifty  percent  (50%) of the shares of the  Company  entitled to
vote are  exchanged,  then:  (i) if there is no successor  to the  Company,  the
Company  shall have the right to exercise its  Purchase  Option as to all or any
portion of the Stock then subject to the Purchase  Option set forth above to the
same extent as if  Purchaser's  employment by the Company had ceased on the date
preceding the date of  consummation  of said event or  transaction,  or (ii) the
Purchase  Option  may be  assigned  to any  successor  of the  Company,  and the
Purchase  Option  shall apply if  Purchaser  shall cease for any reason to be an
employee of such  successor on the same basis as set forth above.  In that case,
references herein to the "Company" shall be deemed to refer to such successor.

                  (d) As used herein,  employment with the Company shall include
employment with an affiliate of the Company.

                  (e) This  Agreement is not an employment  contract and nothing
in this Agreement shall be deemed to create in any way whatsoever any obligation
on the part of  Purchaser  to continue in the employ of the  Company,  or of the
Company to continue Purchaser in the employ of the Company.

                  (f) In the  event  that the  Stock's  Fair  Market  Value  (as
defined  in the Plan) is equal to or exceeds  the Option  Price on the date that
the Purchaser  ceases to be employed,  the Company  shall  exercise its Purchase
Option to the extent permitted by law.

         3. The Purchase  Option may be exercised  by giving  written  notice of
exercise delivered or mailed as provided in paragraph 14. Upon providing of such
notice and payment or tender of the purchase price, the Company shall become the
legal and  beneficial  owner of the Stock  being  purchased  and all  rights and
interests therein or related thereto.

                                       2.
<PAGE>

         4. If from time to time during the term of the Purchase Option there is
any stock  dividend  or  liquidating  dividend  or  distribution  of cash and/or
property,  stock split or other change in the  character or amount of any of the
outstanding  securities of the Company,  then,  in such event,  any and all new,
substituted  or additional  securities or other  property to which  Purchaser is
entitled by reason of his ownership of Stock will be immediately  subject to the
Purchase  Option and be  included in the word  "Stock"  for all  purposes of the
Purchase  Option  with the same  force and  effect as the  shares of Stock  then
subject to the  Purchase  Option.  While the total Option Price shall remain the
same after each such event, the Option Price per share of Stock upon exercise of
the Purchase Option shall be appropriately adjusted.

         5. All  certificates  representing  any shares of Stock of the  Company
subject to the provisions of this Agreement shall have endorsed  thereon legends
in substantially the following form:

                           (i) "The shares  represented by this  certificate are
subject to an option  set forth in an  agreement  between  the  Company  and the
registered holder, or his predecessor in interest, a copy of which is on file at
the principal office of this Company.  Any transfer or attempted transfer of any
shares subject to such option is void without the prior express  written consent
of the issuer of these shares."

                           (ii) "These securities have not been registered under
the Securities Act of 1933. They may not be sold,  offered for sale,  pledged or
hypothecated  in the absence of an  effective  registration  statement as to the
securities  under said Act or an opinion of counsel  satisfactory to the Company
that such registration is not required."

                           (iii) Any legend required to be placed thereon by the
California Commissioner of Corporations.

         6. Purchaser  acknowledges that he is aware that the Stock to be issued
to him by the Company  pursuant to this Agreement has not been registered  under
the  Securities  Act of 1933,  as  amended  (the  "Act"),  on the basis  that no
distribution  or public  offering  of the Stock is to be  effected,  and in this
connection   acknowledges   that  the  Company  is  relying  on  the   following
representations:  Purchaser  warrants and  represents  to the Company that he is
acquiring  the  Stock  for  investment  and not with any  present  intention  of
distributing  or  selling  the Stock and he does not  presently  have  reason to
anticipate any change in circumstances or any particular occasion or event which
would cause him to sell the Stock.  Purchaser  recognizes that the Stock must be
held  indefinitely  unless  it is  subsequently  registered  under the Act or an
exemption from such registration is available and, further,  recognizes that the
Company  is under no  obligation  to  register  the Stock or to comply  with any
exemption from such registration.

         7.  Purchaser is aware that the Stock may not be sold  pursuant to Rule
144 adopted under the Act unless certain  conditions are met and until Purchaser
has held the Stock for at least two (2) years.  Among the  conditions for use of
Rule 144 is the availability

                                       3.
<PAGE>

of specified current public information about the Company.  Purchaser recognizes
that the Company  presently has no plans to make such  information  available to
the public.

                  Whether or not the Purchase Option is exercised or has lapsed,
Purchaser  further agrees not to make any disposition of any of the Stock in any
event unless and until;

                  (a) There is then in effect a registration statement under the
Act  covering  such  proposed  disposition  and  such  disposition  is  made  in
accordance with such registration statement; or

                  (b) (i)  Purchaser  shall  have  notified  the  Company of the
proposed  disposition  and shall  have  furnished  the  Company  with a detailed
statement of the circumstances  surrounding the proposed  disposition,  and (ii)
Purchaser shall have given the Corporation an opinion of counsel,  which opinion
and  counsel  shall be  satisfactory  to the  Company,  to the effect  that such
disposition will not require registration of the Stock under the Act.

         8. As  security  for his  faithful  performance  of the  terms  of this
Agreement and to insure the availability for delivery of Purchaser's  Stock upon
exercise of the Purchase Option herein provided for,  Purchaser  agrees,  at the
closing  hereunder (or as soon thereafter as  practicable),  to deliver (or have
the Company deliver on the Purchaser's behalf) to and deposit with the Secretary
of the Company ("Escrow Agent"),  as Escrow Agent in this  transaction,  one (1)
stock  assignment  duly endorsed  (with date and number of shares left blank) in
the  form  attached  hereto  as  Exhibit  A,  together  with  a  certificate  or
certificates  evidencing all of the Stock subject to the Purchase  Option;  said
documents  are to be held by the Escrow Agent and delivered by said Escrow Agent
pursuant to the Joint Escrow Instructions of the Company and Purchaser set forth
in Exhibit B attached hereto and  incorporated  herein by this reference,  which
instructions  shall  also  be  delivered  to the  Escrow  Agent  at the  closing
hereunder (or as soon thereafter as practicable).

         9. Purchaser shall not sell or transfer any of the Stock subject to the
Purchase Option or any interest  therein so long as such Stock is subject to the
Purchase Option.

         10. The Company  shall not be required (i) to transfer on its books any
shares of Stock of the  Company  which  shall have been sold or  transferred  in
violation of any of the  provisions set forth in this Agreement or (ii) to treat
as owner of such  shares or to accord  the right to vote as such owner or to pay
dividends to any transferee to whom such shares shall have been so transferred.

         11. Subject to the  provisions of paragraphs 9 and 10 above,  Purchaser
(but not any unapproved  transferee)  shall,  during the term of this Agreement,
exercise all rights and  privileges of a stockholder of the Company with respect
to the Stock.

         12. Purchaser  acknowledges  receipt of a copy of Section 260.141.11 of
Title 10 of the California Administrative Code, attached hereto as Exhibit C.

                                       4.
<PAGE>


         13. The parties agree to execute such further  instruments  and to take
such further  action as  reasonably  may be necessary to carry out the intent of
this Agreement.

         14.  Any  notice  required  or  permitted  hereunder  shall be given in
writing and shall be deemed  effectively  given upon  personal  delivery or upon
deposit in any United States Post Office Box, by  registered  or certified  mail
with  postage  and fees  prepaid,  addressed  to the other  party  hereto at his
address  hereinafter  shown below his signature or at such other address as such
part may  designate by ten (10) days' advance  written  notice to the other part
hereto.

         15.  This  Agreement  shall  bind  and  inure  to  the  benefit  of the
successors  and  assigns of the  Company  and,  subject to the  restrictions  on
transfer  herein  set  forth,  inure  to the  benefit  of and  be  binding  upon
Purchaser,  his  heirs,  executors,  administrators,  successors,  and  assigns.
Without  limiting the  generality of the foregoing,  the Purchase  Option of the
Company hereunder shall be assignable by the Company at any time or from time to
time,  in whole or in part.  Should the right of  repurchase  be assigned by the
Company, the assignee shall pay to the Company cash equal to the excess, if any,
of the Stock's Fair Market Value (as defined in the Plan) over the Option Price.

         IN WITNESS WHEREOF,  the parties hereto have executed this Agreement as
of the 13th day of June, 1996.

                                                                   EXHIBIT 10.28

                       MPSS TECHNOLOGY SERVICES AGREEMENT



         THIS MPSS TECHNOLOGY  SERVICES  AGREEMENT (the "Agreement") is made and
entered into as of October 23, 1996 (the "Effective Date") by LYNX THERAPEUTICS,
INC.,  a  Delaware  corporation  ("Lynx"),   and  BASF   AKTIENGESELLSCHAFT,   a
corporation organized under the laws of Germany ("BASF").

                                    RECITALS

         WHEREAS,  Lynx  owns  certain  inventions,   methods  and  intellectual
property relating to a novel technique for determining cDNA sequence information
from a sample; and

         WHEREAS,  Lynx  is  commercializing  such  techniques  for  use  in the
analysis of cDNA libraries for research and commercial purposes; and

         WHEREAS,  BASF  desires  to secure  access to Lynx's  library  analysis
capabilities  and  services  on the terms set forth  herein  and is  willing  to
provide financial support for Lynx's development work;

         NOW  THEREFORE,  in  consideration  of the  foregoing  premises and the
covenants and promises contained in this Agreement,  the parties hereto agree as
follows:

1.       DEFINITIONS

         Capitalized  terms  use in  this  Agreement  shall  have  the  meanings
ascribed to them in the following  sections of this Article 1, unless  otherwise
defined in this Agreement.

         1.1 "Affiliate" means a corporation, partnership, entity, person, firm,
company, or joint venture that controls, is controlled by or is under the common
control with the referenced  Party. For the purposes of this definition the word
"control" (including, with correlative meaning, the terms "controlled by" or "is
under the common control with") means the power to direct or cause the direction
of the management and policies of such entity, or the ownership of a least fifty
percent (50%) of the voting stock of such entity;  provided,  however,  that, if
the applicable law of the  jurisdiction of organization of such entity prohibits
ownership by a Party of fifty percent (50%) or more,  then "control"  shall mean
the  ownership  of the  maximum  percentage  of the voting  stock of such entity
allowed by such applicable law.

         1.2  "Massively  Parallel  Signature  Sequencing"  or "MPSS"  means the
parallel  acquisition  of at  least  [REDACT]  contiguous  bases  (a  "Signature
Sequence")  from each of at least [REDACT]  templates  sampled from a given cell
culture or tissue cDNA library.

CONFIDENTIAL TREATMENT REQUESTED

<PAGE>


         1.3  "Milestone"  means  the  achievement  by  Lynx  of  the  technical
parameters  with  respect  to MPSS  performance  that are set forth in Exhibit A
hereto.

         1.4 "MPSS Library  Analysis"  means a report  containing  each [REDACT]
base  sequence  and its  abundance  within the  [REDACT] or more cDNA  templates
extracted from a given sample.

2.       LYNX MPSS SERVICES

         2.1 Access Fee. In consideration  of Lynx's  commitment to provide BASF
with the  services  hereinafter  described,  BASF agrees to pay to Lynx five and
one-half  million  U.S.  dollars  ($5,500,000)  within  thirty  (30) days of the
Effective Date (the "Initial  Payment").  BASF shall pay Lynx an additional five
and one-half  million U.S.  dollars  ($5,500,000)  within thirty (30) days after
Lynx  notifies  BASF that the Milestone has been achieved and provides BASF with
the data demonstrating  achievement of such milestone (the "Milestone Payment").
The  obligations  of BASF to make such  additional  payment  and any  subsequent
payments  under this  Agreement  shall  only come into  effect if the patent due
diligence of BASF does not reveal by January 15, 1997 that Lynx could be blocked
from  performing  MPSS Library  Analyses in the United  States.  If such payment
obligations  do not come into effect due to the  foregoing,  then this Agreement
shall terminate on January 15, 1997.

         2.2 Initial  Subscription  Period.  Within  thirty (30) days after BASF
delivers to Lynx the Milestone  Payment  required  under Section 2.1, BASF shall
make a payment to Lynx of four million U.S.  dollars  ($4,000,000) in respect of
MPSS  analysis  services  to be  provided  during  the first  half of an initial
subscription period (the "First Subscription Payment"). On the first anniversary
of the  commencement  of the  initial  subscription  period,  BASF shall make an
additional payment to Lynx of four million U.S. dollars  ($4,000,000) in respect
of  the  MPSS  analysis  services  to  be  performed   hereunder.   The  initial
subscription period shall commence on the date the First Subscription Payment is
due, and shall terminate on the date that is twenty-four  (24) months after such
date. During such initial subscription period, BASF shall be entitled to receive
from Lynx,  without  further  charge,  MPSS Library  Analyses for up to [REDACT]
separate cDNA library samples  delivered to Lynx by BASF during such period.  In
addition,  during the same period,  BASF shall be entitled to order from Lynx up
to [REDACT]  additional  MPSS  Library  Analyses,  for which BASF shall pay Lynx
[REDACT]  per  additional  MPSS Library  Analysis.  If at the end of the initial
subscription  period,  BASF submits for MPSS  analysis  less than  [REDACT] cDNA
library  samples,  BASF may  submit the  balance,  but in any case not more than
[REDACT],  for analysis during the following 24 months [REDACT] (the "Carry Over
Period").

         2.3 Renewal of  Subscription.  BASF may, at its option and upon 30 days
prior written notice, elect to extend its subscription on the terms set forth in
Section  2.2 above for  additional  subsequent  one year  periods,  by making in
respect of each renewal period a payment to Lynx of [REDACT] prior to expiration
of the then  current  subscription  period.

CONFIDENTIAL TREATMENT REQUESTED

                                       2.
<PAGE>


Each renewal shall be subject to increases  annually to reflect increases in the
U.S.  Producer Price Index--All  Urban Producers  during the prior  subscription
period.  This Agreement shall expire at the end of the last subscription  period
paid for by BASF as provided  for in  Sections  2.2 and 2.3, if BASF fails to so
renew its subscription  for MPSS services for the subsequent  period as provided
in this Section 2.3.

         2.4 Informatics.  The parties  acknowledge that Lynx intends to develop
software to facilitate the analysis of data secured from MPSS Library  Analyses.
Lynx agrees that BASF may at its election obtain for its own use during the term
of this Agreement object copies of such software [REDACT].

         2.5 Ownership of Technology.  Subject to 2.7 below,  BASF  acknowledges
and  agrees  that  any  and  all  inventions   (patentable   or   unpatentable),
information,  know-how,  techniques,  methods,  materials  or  other  technology
developed, discovered or made by Lynx during the development work shall be owned
entirely by Lynx and shall be  disclosed  to BASF only to the extent Lynx elects
to do so. Lynx shall own and have the sole and exclusive  right to prosecute and
maintain all patents and patent applications covering any such technology.

         2.6 Access to Lynx Reference Data Base.  Lynx will build and maintain a
reference  data base  containing  MPSS  information  and data  derived from MPSS
analyses of a variety of reference tissue and cell types.  Lynx agrees that BASF
shall  have  access to this  reference  data base in order to  enable  BASF,  by
comparing  the results of MPSS Library  Analyses with data  generated  from MPSS
Library Analyses of pertinent  reference samples, to minimize the work that BASF
may need to do to validate data  obtained from its samples.  Lynx agrees to make
this  reference  data base  available  to BASF as it is built during the term of
this Agreement [REDACT] to BASF.

         2.7 BASF Intellectual Property.  BASF shall own the entire right, title
and interest in and to the cDNA libraries that it sends to Lynx for analysis and
the results of the MPSS  Library  Analyses of such  libraries  prepared for BASF
pursuant to this  Agreement.  Lynx agrees that it shall treat the  identity  and
nature  of such  cDNA  libraries  delivered  to Lynx by BASF  hereunder  and the
results of the related MPSS Library Analyses as the  "Confidential  Information"
of BASF  pursuant  to  Article  3  hereof.  Nevertheless,  BASF  agrees  to give
appropriate  credit to Lynx in any  scientific  publication of its research that
relies on such results.

3.       CONFIDENTIALITY

         3.1 Confidentiality.  All knowledge,  know-how, practices, processes or
other  information  (hereinafter  referred  to  as  "Confidential  Information")
disclosed  by one  party to the  other  (the  "Receiving  Party")  and  which is

and designated as Confidential Information,  shall be received and maintained by
such party in strict  confidence  and shall not be disclosed to any third party.
The Receiving Party shall not use said Confidential  Information for any purpose
other than those purposes  specified in this Agreement.  The Receiving Party may
disclose  Confidential  Information  for  the  purposes  of  this  Agreement  to
Affiliates,  employees  or  consultants  who are  obliged  to  comply  with this
confidentiality  provision.  This Section 3.1 shall survive for a period of five
(5) years from  expiration or termination of this Agreement.  The  nondisclosure
obligations  of this  Section  3.1 shall not apply to  Confidential  Information
which the  Receiving  Party can  establish by  competent  evidence (i) is in the
public domain prior or subsequent to disclosure  without breach by the Receiving
Party, (ii) was in the Receiving  Party's  possession at the time of disclosure,
(iii) is received by Receiving Party from a third party who has the lawful right
to disclose it or (iv) is disclosed as required by law or regulation or with the
written consent of the other party.

4.       TERM AND TERMINATION

         4.1 Term. This Agreement shall expire two years from the Effective Date
if the Milestone  has not been  achieved as of such date.  If such  milestone is
achieved before such date, this Agreement shall expire at the end of the initial
subscription period or the Carry Over Period both as provided for in Section 2.2
or, if the  subscription  period is renewed under Section 2.3, at the end of the
last subscription period to be paid for by BASF under Section 2.3.

         4.2 Termination for Material Breach. Each party shall have the right to
terminate this Agreement,  in addition to pursuing any remedies  available under
law or in equity,  upon sixty (60) days written notice to the other party if the
other party is in material breach of this Agreement.  Such termination shall not
be  effective  if the other party cures such  breach  within  sixty (60) days of
receiving written notice of breach; thirty (30) days where the alleged breach is
failure to pay money when due.

         4.3 Effect of Termination; Survival. Upon any expiration or termination
of this  Agreement,  BASF will pay to Lynx all amounts  that have been earned by
Lynx through the expiration or termination  date. Lynx will return any remaining
samples  provided by BASF,  supply BASF with any MPSS  Library  Analyses of BASF
samples  generated prior to the expiration or termination date, and, in the case
of  termination,  shall  return to BASF any  advance  payment to the extent such
advance payment was intended to serve as payment for services  subsequent to the
termination  date.  Section  3.1  shall  survive  for five (5)  years  following
expiration or termination  with respect to  Confidential  Information  disclosed
prior to expiration or termination.

                                    MILESTONE

         The achievement of the Milestone will be demonstrated as follows:

         1. The  parties  will  jointly  select a cell  system  or cell  culture
suitable for this demonstration experiment.

         2. One portion of the cell culture  will be  "induced"  using an agreed
upon inducer, such as a [REDACT], for a specified period, such as [REDACT].

         3. Lynx will take [REDACT]  samples from the  "uninduced"  and [REDACT]
from the  "induced"  system or culture,  following  its internal  protocols  for
sampling.

         4. Lynx will extract the cDNA  contained  in each of the [REDACT]  such
samples, using its internal protocols for cDNA extraction.

         5. The cDNA extracted from each of the [REDACT] samples will be divided
into [REDACT] parts,  and a separate MPSS Library  Analysis will be conducted on
all of the resulting cDNA samples.

         6. If the data  generated  from all  [REDACT]  analyses  of each of the
[REDACT]  cultures  are  within the set  (induced  or  uninduced)  substantially
identical, but yet between the sets substantially different,  then the Milestone
has been achieved.

         on more favourable terms as offered to the other Partner or its Holding
         Company,  the  transferor  must  first  offer  the  shares to the other

         rejection to make or obtain from a third party an Offer superior to the
         rejected offer in some material respect (the "Second" Offer").

         Partner who made the First Offer may submit a new Offer within [REDACT]

         A. The Board of Directors of  Spectragen  and Lynx believe it is in the
best interests of each company and their respective stockholders that Spectragen
and Lynx combine into a single company through the Delaware  statutory merger of
Spectragen with and into Lynx (the "Merger") and, in furtherance  thereof,  have
approved the Merger.

         B. Pursuant to the Merger,  among other things,  the outstanding shares
of Common Stock of Spectragen ("Spectragen Common Stock"), other than those held
by Lynx,  shall be converted  into shares of Common Stock of Lynx ("Lynx  Common
Stock") as determined herein.

         C. The parties intend, by executing this Agreement,  to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "Code").

         NOW,  THEREFORE,  in  consideration  of  the  covenants  promises,  and
representations set forth herein, and for other good and valuable  consideration
the parties agree as follows:

1.       THE MERGER

provisions  of,  Delaware  Law (the time of such  filing  being  the  "Effective
Time").  The closing of the  transactions  contemplated  hereby (the  "Closing")

corporation  after  the  Merger  is  hereinafter  sometimes  referred  to as the
"Surviving Corporation."



<PAGE>


         1.3 Effect of the  Merger.  At the  Effective  Time,  the effect of the
Merger shall be as provided under Delaware Law.  Without limiting the generality
of the foregoing,  and subject thereto,  at the Effective Time all the property,
rights,  privileges,  powers and franchises of Spectragen and Lynx shall vest in
the Surviving Corporation,  and all debts,  liabilities and duties of Spectragen
and Lynx  shall  become  the  debts,  liabilities  and  duties of the  Surviving
Corporation.

         1.4      Articles of Incorporation; Bylaws.

                  (a) Unless otherwise determined by Lynx prior to the Effective
Time, at the Effective  Time the  Certificate  of  Incorporation  of Lynx, as in
effect  immediately  prior to the Effective  Time,  shall be the  Certificate of
Incorporation of the Surviving  Corporation until thereafter amended as provided
by law and such Articles of Incorporation.

                  (b) The Bylaws of Lynx, as in effect  immediately prior to the
Effective  Time,  shall  be  the  Bylaws  of  the  Surviving  Corporation  until
thereafter amended.

         1.5 Directors and Officers.  The directors of Lynx immediately prior to
the Effective time shall be the initial directors of the Surviving  Corporation,
each to hold office in accordance with the Articles of Incorporation  and Bylaws
of the Surviving Corporation,  and the officers of Lynx immediately prior to the
Effective Time shall be the initial  officers of the Surviving  Corporation,  in
each case until their  respective  successors  are duly elected or appointed and

         1.6 Manner of Converting Stock. At the Effective Time, by virtue of the
Merger and without any action on the part of Lynx, Spectragen,  or the holder of
any of the following securities:

                  (a)  Conversion  of  Spectragen  Common  Stock.  Each share of
common stock, par value $.001 per share, of Spectragen (the  "Spectragen  Common
Stock") issued and  outstanding  immediately  prior to the Effective Time (other
than any shares of Spectragen  Common Stock to be cancelled  pursuant to Section
1.6(b) and any  Dissenting  Shares (as  defined  and to the extent  provided  in
Section   1.7(a))  will  be  cancelled   and   extinguished   and  be  converted
automatically into the right to receive 1.3 shares of Lynx Common Stock.

                  (b)  Cancellation  of Lynx-Owned and  Spectragen-Owned  Stock.
Each  share  of  Spectragen  Common  and/or  Preferred  Stock  owned  by Lynx or
Spectragen  immediately  prior to the  Effective  Time  shall be  cancelled  and
extinguished without any conversion thereof.

                  (c) Stock  Options.  At the  Effective  Time,  all  options to
purchase Spectragen Common Stock then outstanding under the Amended and Restated

<PAGE>

Option Plan (the  "Spectragen  Stock  Option  Plan") shall be assumed by Lynx in
accordance with Section 2.1.

                  (d) Fractional  Shares.  No fraction of a share of Lynx Common
Stock will be issued,  but in lieu thereof  each holder of shares of  Spectragen
Stock who would  otherwise  be  entitled to a fraction of a share of Lynx Common
Stock  (after  aggregating  all  fractional  shares of Lynx  Common  Stock to be
received by such holder) shall be entitled to receive from Lynx a whole share of
Lynx Common Stock.

         1.7      Dissenting Shares.

                  (a)  Notwithstanding  any  provision of this  Agreement to the
contrary,  any shares of capital  stock of  Spectragen  held by a holder who has
demanded  and  perfected  appraisal  rights for such shares in  accordance  with
Section 262 of the Delaware General Corporation Law and who, as of the Effective
Time, has not effectively withdrawn such appraisal rights ("Dissenting Shares"),
shall not be  converted  into or  represent a right to receive Lynx Common Stock
pursuant to Section 1.6, but the holder  thereof  shall only be entitled to such
rights as are granted by Delaware Law.

                  (b)  Notwithstanding  the provisions of subsection (a), if any
holder of shares of capital  stock of Spectragen  who demands  appraisal of such
shares under  Delaware Law shall  effectively  withdraw the right to  appraisal,
then,  as of the later of the Effective  Time and the  occurrence of such event,
such holder's  shares shall  automatically  be converted into and represent only
the right to receive Lynx Common Stock, without interest thereon, upon surrender
of the certificate representing such shares.

                  (c)  Spectragen  shall  give  Lynx (i)  prompt  notice  of any
written  demands for  appraisal  of any shares of capital  stock of  Spectragen,
withdrawals  of such  demands,  and any other  instruments  served  pursuant  to
Delaware Law and received by Spectragen and (ii) the  opportunity to participate
in all negotiations and proceedings which take place prior to the Effective Time
with respect to demands for appraisal under Delaware Law.  Spectragen shall not,
except  with the prior  written  consent of Lynx,  voluntarily  make any payment
before the  Effective  Time with respect to any demands for appraisal of capital
stock of Spectragen or offer to settle or settle any such demands.

         1.8      Surrender of Certificates.

                  (a) Exchange of Certificates.  As soon as is practicable after
the Effective Time, Lynx shall cause its transfer agent to prepare  certificates
representing the shares of Lynx Common Stock issuable pursuant to Section 1.6 in
exchange  for  outstanding  shares of  Spectragen  common  stock  (the "New Lynx
Certificates").  All Certificates, which prior to the Effective Time represented
shares of  Spectragen  Common  Stock and were  held in  escrow

<PAGE>


pursuant to the Stockholders Agreement (the "Spectragen Certificates"), shall be
transferred  from Cooley  Godward LLP ("the Escrow Agent") for completion of the
exchange.  The  transfer  agent  shall  then  issue  the  appropriate  New  Lynx
Certificates.  The Spectragen Certificates shall then be cancelled. The transfer
agent shall then  redeliver  the New Lynx  Certificates  to the Escrow Agent for
distribution  according to the terms set forth in the Stockholders Agreement and
the applicable stock purchase agreement.

                  (b)  Distributions  With  Respect to  Unexchanged  Shares.  No
dividends or other distributions  declared or made after the Effective Time with
respect to Lynx Common Stock with a record date after the Effective time will be
paid to the holder of any  unsurrendered  Certificate with respect to the shares
of Lynx Common Stock represented  thereby until the holder of record of such New
Lynx Certificate  shall surrender such  Certificate.  Subject to applicable law,
following surrender of any such New Lynx Certificate, there shall be paid to the
record holder of the certificates representing whole shares of Lynx Common Stock
issued in exchange  therefor,  without interest,  at the time of such surrender,
the amount of  dividends  or other  distributions  with a record  date after the
Effective time theretofore paid with respect to such whole shares of Lynx Common
Stock.

                  (c) Transfers of Ownership.  If any  certificate for shares of
Lynx  Common  Stock is to be  issued  in a name  other  than  that in which  the
certificate  surrendered  in  exchange  therefor  is  registered,  it  will be a
condition of the issuance  thereof that the  certificate so surrendered  will be
properly  endorsed and otherwise in proper form for transfer and that the person
requesting  such exchange  will have paid to Lynx or any agent  designated by it
any transfer or other taxes  required by reason of the issuance of a certificate
for shares of Lynx  Common  Stock in any name other than that of the  registered
holder of the  certificate  surrendered,  or established to the  satisfaction of
Lynx or any  agent  designated  by it that  such  tax  has  been  paid or is not
payable.

                  (d) No Liability.  Notwithstanding anything to the contrary in
this Section 1.8, none of the Escrow Agent,  the  Surviving  Corporation  or any
party  hereto  shall be liable to a holder  of  shares of Lynx  Common  Stock or
Spectragen  Common  Stock  for any  amount  properly  paid to a public  official
pursuant to any applicable abandoned property, escheat or similar law.

         1.9 No Further  Ownership Rights in Spectragen Common Stock. All shares
of Lynx  Common  Stock  issued  upon the  surrender  for  exchange  of shares of
Spectragen  Common Stock in accordance with the terms hereof (including any cash
paid  in  respect  thereof)  shall  be  deemed  to  have  been  issued  in  full
satisfaction of all rights pertaining to such shares of Spectragen Common Stock,
and there shall be no further  registration  of  transfers on the records of the
Surviving   Corporation  of  shares  of  Spectragen   Common  Stock  which  were
outstanding  immediately  prior to the Effective  Time.  If, after the Effective
Time,  Certificates  are 

<PAGE>


presented to the Surviving  Corporation for any reason,  they shall be cancelled
and exchanged as provided in this Section 1.

         1.10  Lost,  Stolen  or  Destroyed  Certificates.   In  the  event  any
certificates  evidencing shares of Spectragen Common Stock shall have been lost,
stolen or  destroyed,  the Escrow  Agent shall issue in exchange  for such lost,
stolen or destroyed  certificates,  upon the making of an affidavit of that fact
by the holder thereof,  such shares of Lynx Common Stock and cash for fractional
shares, if any, as may be required pursuant to Section 1.6;  provided,  however,
that Lynx may, in its  discretion  and as a condition  precedent to the issuance
thereof,  require the owner of such lost,  stolen or destroyed  certificates  to
deliver a bond in such sum as it may reasonably  direct as indemnity against any
claim that may be made against  Lynx or the  Exchange  Agent with respect to the
certificates alleged to have been lost, stolen or destroyed.

         1.11 Tax Consequences and Accounting  Treatment.  It is intended by the
parties  hereto that the Merger  shall  constitute a  reorganization  within the
meaning of Section 368 of the Internal Revenue Code of 1986, as amended.

         1.12 Taking of Necessary Action;  Further Action. If, at any time after
the Effective  Time,  any such further action is necessary or desirable to carry
out the purposes of this  Agreement  and to vest in Surviving  Corporation  with
full right, title and possession to all assets,  property,  rights,  privileges,
powers,  and  Franchises of  Spectragen,  the Officers and Directors of Lynx and
Spectragen are fully authorized in the name of their respective corporations, to
take, and will take, all such lawful and necessary action.

2.       STOCK OPTIONS.

         2.1  Assumption of Spectragen  Options by Lynx. At the Effective  Time,
each  outstanding  option to purchase shares of Spectragen  Common Stock (each a
"Spectragen  Option") under the Spectragen Stock Option Plan,  whether vested or
unvested,  shall  be, in  connection  with the  Merger,  assumed  by Lynx.  Each
Spectragen  Option so assumed by Lynx under this  Agreement  shall  continue  to
have,  and be  subject  to,  the same  terms  and  conditions  set  forth in the
Spectragen Stock Option Plan and as provided in the respective option agreements
immediately  prior to the Effective Time, except that (i) such Spectragen Option
shall be  exercisable  only for that number of whole shares of Lynx Common Stock
equal to the  product of the number of shares of  Spectragen  Common  Stock that
were issuable upon exercise of such Spectragen  Option  immediately prior to the
Effective  Time  multiplied  by 1.3,  rounded up to the nearest  whole number of
shares  of Lynx  Common  Stock,  and (ii) the per share  exercise  price for the
shares of Lynx Common  Stock  issuable  upon  exercise of such  assumed  Company
Option shall be equal the exercise price per share of Spectragen Common Stock at
which such Spectragen Option was exercisable  immediately prior to the Effective
Time divided by 1.3,  rounded up to the nearest  whole cent,  all in  accordance
with the rules of 

<PAGE>


Section 424(a) of the Code, and the regulations promulgated thereunder, and such
rules shall apply even with  respect to options  that are not  "incentive  stock
options" (within the meaning of Section 424 of the Code).

         2.2 Form S-8. Lynx will file a  registration  statement on Form S-8 for
the  outstanding   Spectragen  Common  Stock  Options  (that  are  eligible  for
registration on Form S-8) within thirty (30) calendar days after the Closing.

proceeding   brought  by  an  administrative   agency  or  commission  or  other
governmental authority to instrumentality,  domestic or foreign,  seeking any of
the foregoing be pending;  nor shall there be any action taken,  or any statute,
rule, regulation or order enacted, entered, enforced or deemed applicable to the
Merger, which makes the consummation of the Merger illegal.

                                  CONFIDENTIAL
                              SEPARATION AGREEMENT




         This  Confidential  Separation  Agreement (the  "Agreement") is entered
into between Lynx  Therapeutics,  Inc. (the "Company") and David W. Martin,  Jr.
("Dr. Martin").

         1.  SEPARATION.  Dr.  Martin's  last day of work with the  Company  was
November 1, 1996 (the "Separation  Date").  Effective as of the Separation Date,
Dr.  Martin  hereby  resigns from any and all of his  positions as an officer or
director of the Company and its subsidiaries, including Spectragen, Inc.

         2. ACCRUED  SALARY AND PAID TIME OFF.  The Company has paid Dr.  Martin
all  accrued  salary,  and all accrued and unused  vacation  earned  through the
Separation Date, subject to standard payroll deductions and withholding, and Dr.
Martin acknowledges receipt of such payment.

         3.  SEVERANCE.  In lieu of the severance  benefits  provided for In Dr.
Martin's  Employment  Agreement  dated  as of  April 3,  1995  (the  "Employment
Agreement"),  the  Company  agrees to  provide  Dr.  Martin  with the  severance
benefits described below:

                  a. The Company will  continue to pay Dr.  Martin at the annual
base salary rate of $200,000 in semi-monthly installments for twelve (12) months
from the Separation Date. On or prior to the tenth day of each month, Dr. Martin
shall  provide the Company with a written  statement of any income that has been
earned by him from other sources of employment  (but  excluding for this purpose
director  fees paid to Dr.  Martin in  respect  of  directorships  he  currently
holds),  and fifty  percent  (50%) of any such  earnings  shall be  applied to a
reduction of payments due to Dr. Martin under this subparagraph.

                  b. The Company will advance  $17,333 to Dr. Martin within five
(5)  days of  execution  of  this  Separation  Agreement  pursuant  to the  Loan
Agreement dated as of May 1, 1995, in order to bring the  outstanding  principal
balance of such loan to $150,000.  Such advance will be applied to the reduction
of debt to the company as stated in Paragraph 5 below. No further  advances will
be made under such  agreement,  and the Company agrees to forgive the principal,
and accrued interest, effective January 1, 1997 (an aggregate of $157,861.58).

                  c. Because the Company believes, on the advice of its counsel,
that  the  severance  payment  and the  forgiven  Promissory  Note  balance  (as
described in 3.b.  above) may be treated as taxable  income to Dr.  Martin under
current state and federal income tax statutes and  regulations,  the Company may
deduct taxes from its cash payments due to Dr. Martin hereunder.


<PAGE>


         4. HEALTH  INSURANCE.  To the extent permitted by the federal COBRA law
and by the Company's current group health insurance policies, Dr. Martin will be
eligible to continue his medical and dental insurance benefits.  Dr. Martin will
be provided  with a separate  notice of his COBRA  rights.  If Dr. Martin elects
continued  coverage under COBRA,  Dr. Martin will be responsible for the payment
of the COBRA premiums.

         5. EQUITY;  PROMISSORY  NOTE. In connection  with the exercise of stock
options granted to him, Dr. Martin and the Company entered into a Stock Purchase
Agreement dated as of May 1, 1995 (the "Stock Purchase  Agreement")  pursuant to
which Dr. Martin purchased 250,000 shares of Common Stock with a Promissory Note
in the principal amount of $450,000.  Together with accrued interest, the amount
outstanding under such note was $498,060 at the Separation Date. Under the terms
of the Stock  Purchase  Agreement  157,500  shares are  currently  unvested  and
subject to a repurchase  option in favor of the Company at an aggregate price of
$329,273.  The Company hereby exercises its option, and the exercise price shall
be applied to payment of the Promissory Note (reducing the balance to $168,787).
The advance of $17,333  described in Paragraph 3.b above will also be applied to
payment of the Promissory  Note  (reducing the balance to $151,454).  Dr. Martin
agrees to pay the remaining  balance in full on or before November 30, 1996, and
acknowledges  and agrees that the Company can and will  exercise its rights as a
secured creditor (including  execution of a sale of collateral in the market) if
such balance is not paid when due. Upon payment in full of the Promissory  Note,
the Company agrees to cancel the Promissory  Note and to deliver to Mr. Martin a
stock certificate representing the balance of the Common Stock currently held in
escrow  pursuant to the Stock Purchase  Agreement as soon as it can be processed
by the Company's transfer agent.

         6. OTHER COMPENSATION OR BENEFITS. Dr. Martin acknowledges that, except
for the closing  costs to which he is entitled per the April 1995  agreement and
as  expressly  provided in this  Agreement,  he will not receive any  additional
compensation, severance or benefits after the Separation Date.

         7. EXPENSE  REIMBURSEMENTS.  Dr. Martin agrees that,  prior to November
30, 1996, he will submit his final documented  expense  reimbursement  statement
reflecting all business  expenses he incurred  through the  Separation  Date, if
any, for which he seeks reimbursement. The Company will reimburse Dr. Martin for
these expenses pursuant to its regular business practice.

         8.  RETURN  OF  COMPANY  PROPERTY.  By the  date of  execution  of this
Agreement, Dr. Martin agrees to return to the Company all Company documents (and
all  copies  thereof)  and  other  Company  property  which  he  has  had in his
possession at any time, including,  but not limited to, Company files, notes and
notebooks,   drawings,   records,   business  plans  and  forecasts,   financial
information,  specifications,  computer-recorded information,  tangible property
(including,  but  not  limited  to,  computers),   credit  cards,  entry  cards,
identification  badges and keys; and, any materials of any kind which contain or
embody any  proprietary  or  confidential  information  of the Company  (and all
reproductions  thereof). Dr. Martin has two notebooks in his possession in which
he has  maintained  a diary of  activities  for the Company and  otherwise.  Dr.
Martin will make

<PAGE>


these  notebooks  available  to the Company  for  copying  but may retain  them,
subject to his continuing obligations regarding confidentiality.

         9. PROPRIETARY  INFORMATION  OBLIGATIONS.  Dr. Martin  acknowledges his
continuing obligations, both during and after his employment, under his Employee
Invention  Agreement to disclose  covered  inventions and not to use or disclose
any confidential or proprietary information of the Company without prior written
authorization from a duly authorized representative of the Company.

         10.  SOLICITATION.  Dr. Martin  agrees that for one year  following the
Separation  Date, he will not,  either  directly or through  others,  solicit or
attempt to solicit any  employee,  consultant or  independent  contractor of the
Company to terminate his or her relationship with the Company in order to become
an employee,  consultant or independent contractor to or for any other person or
business  entity.  Dr.  Martin  agrees not to  initiate  any  dialogue  with any
employee or consultant  of the Company  concerning  the Company's  management or
business affairs.

         11. CONFIDENTIALITY.  The provisions of this Agreement shall be held in
strictest  confidence  by Dr. Martin and the Company and shall not be publicized
or disclosed in any manner whatsoever;  provided, however, that: (a) the parties
may  disclose  this  Agreement  in  confidence  to their  respective  attorneys,
accountants,  auditors,  tax preparers,  and financial advisors; (b) the Company
may disclose this Agreement as necessary to fulfill standard or legally required
corporate reporting or disclosure requirements; and (c) the parties may disclose
this Agreement  insofar as such disclosure may be necessary to enforce its terms
or as otherwise  required by law. The Company will, and Dr. Martin may, disclose
that Dr. Martin has resigned as a result of  differences  over future  corporate
development  priorities and management  style. Dr. Martin agrees not to make any
disclosure  inconsistent  with the  foregoing.  All inquiries from third parties
regarding  references for Dr. Martin shall be referred to Kathy San Roman (Human
Resources), who shall respond only by stating that it is company policy to state
no more then already disclosed and giving Dr. Martin's dates of employment, that
his last position held was President and Chief Executive  Officer,  and his last
salary.

         12.  DISPUTE  RESOLUTION.  Dr.  Martin and the  Company  agree that all
disputes,  claims,  and causes of  action,  in law or  equity,  arising  from or
relating  to  this  Agreement  or  its  enforcement,   performance,  breach,  or
interpretation  shall be resolved solely and  exclusively by confidential  final
and   binding   arbitration    through   Judicial    Arbitration   &   Mediation
Services/Endispute,  Inc.  ("JAMS"),  in San  Francisco,  California,  under the
then-existing  JAMS  arbitration  rules.  However,  nothing  in this  section is
intended to prevent  either party from obtaining  injunctive  relief in court to
prevent irreparable harm pending the conclusion of any such arbitration.

         13. RELEASE. In exchange for the payments and other consideration under
this Agreement to which he would not otherwise be entitled, Dr. Martin agrees to
execute the Employee Agreement and Release attached hereto as Exhibit A.

<PAGE>

         14. MISCELLANEOUS. This Agreement, including Exhibit A, constitutes the
complete,  final and exclusive  embodiment of the entire  agreement  between Dr.
Martin  and the  Company  with  regard  to this  subject  matter  and  expressly
supersedes  the  Employment   Agreement  (but  not  Dr.   Martin's   Proprietary
Information  Agreement,  which remains in full force and effect).  It is entered
into without reliance on any promise or  representation,  written or oral, other
than  those  expressly  contained  herein,  and it  supersedes  any  other  such
promises,  warranties or representations.  This Agreement may not be modified or
amended  except in a writing  signed by both Dr.  Martin  and a duly  authorized
officer  of  the  Company.   This  Agreement  shall  bind  the  heirs,  personal
representatives,  successors and assigns of both Dr. Martin and the Company, and
inure to the benefit of both parties,  their heirs,  successors and assigns.  If
any provision of this Agreement is determined to be invalid or unenforceable, in
whole or in part, this determination will not affect any other provision of this
Agreement and the provision in question  shall be modified by the court so as to
be  rendered  enforceable.  Both  parties  acknowledge  that  they  have had the
opportunity  to seek  advice  regarding  this  Agreement  from their  respective
counsel.  This Agreement  shall be deemed to have been entered into and shall be
construed and enforced in accordance with the laws of the State of California as
applied to contracts made and to be performed entirely within California.

by me, whether  pursuant to statute or insurance or otherwise,  to indemnity and
defense,  and attorneys fees and costs of defense in connection  with any claims
regarding  any acts or  omissions  within the course and scope of my  employment
and/or directorship with the Company,  nor shall this Agreement or its Exhibit A
constitute a release of any claim for breach of this Agreement
