    THE  FOLLOWING SUMMARY  IS QUALIFIED  IN ITS  ENTIRETY BY  THE MORE DETAILED
INFORMATION, INCLUDING "RISK  FACTORS" AND  THE FINANCIAL  STATEMENTS AND  NOTES
THERETO,  APPEARING  ELSEWHERE  IN  THIS  PROSPECTUS.  THE  DISCUSSION  IN  THIS
PROSPECTUS  CONTAINS   FORWARD-LOOKING  STATEMENTS   THAT  INVOLVE   RISKS   AND
UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS AND THE TIMING OF CERTAIN EVENTS MAY
DIFFER   SIGNIFICANTLY  FROM  THE  RESULTS   DISCUSSED  IN  THE  FORWARD-LOOKING
STATEMENTS. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES  INCLUDE,
BUT  ARE  NOT  LIMITED  TO, THOSE  DISCUSSED  IN  "RISK  FACTORS," "MANAGEMENT'S
DISCUSSION AND ANALYSIS OF  FINANCIAL CONDITION AND  RESULTS OF OPERATIONS"  AND
"BUSINESS."
 
                                  THE COMPANY
 
    Conductus,  Inc. ("Conductus"  or the "Company")  develops, manufactures and
markets electronic  components  and  subsystems based  on  superconductors.  The
unique  properties of superconductors provide  the basis for electronic products
with  significant  potential  performance  advantages  over  products  based  on
competing  materials  such  as  copper  and  semiconductors.  Depending  on  the
application, these advantages  include enhanced  sensitivity, efficiency,  speed
and  operating frequency, as well as reduced power consumption, size, weight and
cost. Conductus is currently focusing significant development, manufacturing and
marketing  efforts  on  applications  for   superconductors  in  the  areas   of
communications, healthcare and instrumentation.
 
    Superconductors  are materials that have the ability to transport electrical
energy with little or no loss when cooled below a "critical" temperature.  Since
its founding in 1987, the Company has focused its product development efforts on
high-temperature  superconducting ("HTS") materials discovered in the 1980s that
can  be   cooled  more   conveniently   and  economically   than   earlier-known
superconducting  materials. Based upon publicly available information, Conductus
believes that its technologies are more  advanced than those of other  companies
or  research  laboratories.  Conductus  combines  advanced  HTS  technology with
expertise  in  electronic  device  and  component  design,  analog  and  digital
electronic  engineering, cryogenic packaging,  mechanical engineering and system
integration.  Conductus   believes  that   systems  containing   superconductive
electronic  technology, if  successfully commercialized,  will offer performance
that is  unavailable  from  competing  technology,  will  reduce  the  costs  of
performing desired functions, or, in many cases, will do both.
 
    In  the communications market, Conductus is developing filter subsystems for
cellular and  personal  communication  services  ("PCS")  base  stations.  These
superconducting  filter subsystems  could provide  significant benefits  in base
station performance and reduce the size of the filter components. The Company is
developing and testing prototype integrated  subsystems that are designed to  be
easily integrated into new base stations or to allow cost-effective retrofitting
of  existing base  stations. Laboratory  and initial  field tests  of Conductus'
cellular  filter   subsystems  conducted   by  industry   representatives   have
demonstrated  performance improvements  over conventional  technology, including
enhanced base  station  receiver range.  Conductus  expects to  make  its  first
shipments  of  cellular filter  subsystems  in late  1996.  For the  PCS market,
Conductus is developing an integrated filter subsystem under a joint development
agreement with Lucent Technologies, Inc. ("Lucent"). The first field test of the
initial prototype of the  receiver portion of the  Conductus subsystem has  been
conducted  by Lucent. The Company believes  that providing its technology at the
subsystem level to selected OEM systems manufacturers such as Lucent will  allow
it to most rapidly and efficiently expand both its product line and its customer
base.
 
    In  the  healthcare market,  Conductus is  developing and  testing prototype
superconductive receiver  subsystems for  several  types of  magnetic  resonance
instruments.  Conductus is developing  a family of  probe subsystems for nuclear
magnetic  resonance   ("NMR")  spectroscopy   systems  for   Varian   Associates
("Varian"),  a leading manufacturer  of these systems.  In March 1996, Conductus
began manufacturing and selling two NMR probe types through Varian. The  Company
anticipates that it will introduce a third NMR probe type for commercial sale by
the  end of 1996. Conductus also  is developing receiver subsystems for magnetic
resonance imaging  ("MRI") scanners  under a  joint development  agreement  with
Siemens AG ("Siemens").
 
    In  the instrumentation  market, Conductus currently  manufactures and sells
superconducting sensors  called  Superconducting  Quantum  Interference  Devices
("SQUIDs"),  which can be used in electronic instruments to detect and precisely
locate  extremely  weak  magnetic  signals.  Conductus  is  also  marketing  and
developing  a variety of electronic components  and instruments based upon SQUID
technology.
 
    Conductus has leveraged its resources by developing superconductive products
in collaboration with corporate partners that are market and technology leaders,
research laboratories and government agencies. Since its inception, the  Company
has  received approximately $25.5  million in external  funding for research and
development, primarily from agencies of  the U.S. government, and currently  has
approximately  $5.6 million in  contracts and grants and  $7.8 million in awards
for future research and development.
 
    Conductus was incorporated in  Delaware in 1987.  Its principal offices  are
located  at 969 W. Maude Avenue,  Sunnyvale, California 94086, and its telephone
number is (408) 523-9950.

                                  RISK FACTORS
 
    IN  ADDITION  TO  THE  OTHER  INFORMATION  IN  THIS  PROSPECTUS, PROSPECTIVE
INVESTORS SHOULD CONSIDER THE FOLLOWING  RISK FACTORS INHERENT IN AND  AFFECTING
THE  BUSINESS  OF  THE  COMPANY.  THE  DISCUSSION  IN  THIS  PROSPECTUS CONTAINS
FORWARD-LOOKING STATEMENTS THAT INVOLVE  RISKS AND UNCERTAINTIES. THE  COMPANY'S
ACTUAL  RESULTS AND THE  TIMING OF CERTAIN EVENTS  MAY DIFFER SIGNIFICANTLY FROM
THE RESULTS  DISCUSSED IN  THE FORWARD-LOOKING  STATEMENTS. FACTORS  THAT  COULD
CAUSE  OR CONTRIBUTE TO SUCH DIFFERENCES INCLUDE,  BUT ARE NOT LIMITED TO, THOSE
DISCUSSED BELOW  AND  IN  "MANAGEMENT'S DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS" AND "BUSINESS."
 
    EARLY  STAGE  OF  THE  SUPERCONDUCTIVE ELECTRONICS  MARKET.    Conductus was
founded in September 1987 and to  date has been engaged principally in  research
and  development  activities.  Although  Conductus has  introduced  a  number of
superconductive electronic products,  most of Conductus'  revenues to date  have
been  derived from research and development contracts. See "Risk Factors -- High
Degree of Dependence upon Government Contracts." The superconductive electronics
market is new, with limited product  commercialization to date. There can be  no
assurance  that  Conductus will  successfully  introduce any  products currently
under  development,  that  Conductus  will  be  able  to  manufacture   adequate
quantities  of any products it introduces at commercially acceptable costs or on
a timely basis or that any such products will offer sufficient price/performance
advantages to achieve market acceptance.  The Company's failure to  successfully
develop,   manufacture   and  commercialize   products  that   offer  sufficient
price/performance advantages  to  achieve  significant market  acceptance  on  a
timely  and cost-effective  basis would  have a  material adverse  effect on the
Company's business, operating results and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    ACCUMULATED   DEFICIT;   UNCERTAINTY   OF   FINANCIAL   RESULTS;   QUARTERLY
FLUCTUATIONS.   As of March 31, 1996,  the Company had accumulated net losses of
approximately $25.6 million. Conductus  expects to incur substantial  additional
losses  at least during 1996 as  it expands operations. Continued development of
the Company's products may  require the commitment  of substantial resources  to
research and development, establishment of additional pilot and commercial-scale
fabrication  processes  and  facilities  and  development  of  enhanced  quality
control, marketing, sales and administrative  capabilities. In order to  achieve
profitability,  Conductus,  on  its  own or  with  collaborative  partners, must
successfully develop, manufacture, introduce and market its potential  products.
There  can  be  no assurance  that  the Company  will  ever be  able  to achieve
profitable  operations  or,  if  profitability  is  achieved,  that  it  can  be
sustained.   In   addition,  the   Company's   operating  results   have  varied
substantially on  a  quarterly  basis  and such  fluctuations  are  expected  to
continue  and  perhaps  increase  in  future periods  as  the  Company  seeks to
commercialize its  products. Factors  that may  affect the  Company's  operating
results  include the timing of government  funding awards, the timing and market
acceptance of new  products or  technological advances  by the  Company and  its
competitors,  the timing of significant orders  from and shipments to customers,
changes in  pricing policies  by the  Company and  its competitors,  the mix  of
distribution  channels  through  which  the  Company's  products  are  sold, the
accuracy of resellers'  forecasts of  end user demand,  regulatory changes,  the
ability  of the Company and its  subcontractors to obtain sufficient supplies of
limited- or  sole-source  components  for the  Company's  products  and  general
economic  conditions  both domestically  and internationally.  See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    HIGH DEGREE OF DEPENDENCE UPON OTHER COMPLEMENTARY TECHNOLOGIES; LIMITED- OR
SOLE-SOURCE SUPPLIERS. Commercial uses  of superconductive products will  depend
generally  on the commercial availability of a number of other technologies such
as   specialized   mechanical   refrigeration   systems,    cryogenically-cooled
semiconductor  technology and  large-area compatible  wafer substrates,  some of
which are  in the  development stage.  Conductus currently  does not  intend  to
devote  significant effort or resources to developing these technologies, and is
dependent on the development activities of  third parties in these areas.  There
can  be no assurance that these  technologies will be successfully developed and
commercialized, or that they will  achieve market acceptance. Moreover,  certain
components  of  Conductus'  subsystems,  including  cryocoolers,  are  currently
obtained from a  single source or  a limited number  of suppliers. Although  the
Company  does not believe that  it is ultimately dependent  upon any supplier of
these components as a sole source or limited source for any critical components,
the inability  of  the Company  to  develop alternative  sources,  if  required,
 
                                       5
<PAGE>
an inability to meet demand, a prolonged interruption in supply or a significant
increase in price of one or more components would have a material adverse effect
on the Company's business, operating results and financial condition.
 
    FOCUS  ON  DEVELOPMENT OF  COMPONENTS AND  SUBSYSTEMS.   Many  of Conductus'
potential products,  if  successfully  developed,  are  likely  to  be  used  as
components or subsystems in systems manufactured and sold by third party systems
manufacturers.  There can be no assurance that these third parties will elect to
incorporate superconductive electronic products in these systems or, if they do,
that related system requirements, such as data processing software and  hardware
capabilities, can or will be successfully developed. Failure of third parties to
successfully  commercialize  complementary  technologies or  to  incorporate the
Company's products into their  systems would have a  material adverse effect  on
Conductus' business, operating results and financial condition.
 
    EXTENSIVE   RELIANCE   ON  COLLABORATIVE   RELATIONSHIPS.     Conductus  has
established and continues to seek  to establish collaborative arrangements  with
corporate   partners,  government  agencies  and  public  and  private  research
institutions to  develop,  manufacture  and  market  superconductive  electronic
products.  Conductus' success  will depend in  large part on  the development of
successful  collaborative  arrangements  with  third  parties,  their  strategic
interest  in the potential  products under development  and their willingness to
purchase any such  products. There can  be no assurance  that Conductus will  be
able  to enter into collaborative arrangements on commercially reasonable terms,
that these arrangements, if established,  will result in successful programs  to
develop,  manufacture or market superconductive electronic products or, if these
programs are successful, that Conductus' collaborative partners will not seek to
manufacture  jointly  developed   products  themselves  or   obtain  them   from
alternative  sources. In addition, these programs may require Conductus to share
control  over  its  development,   manufacturing  and  marketing  programs   and
relinquish rights to its technology, may be subject to unilateral termination by
the  Company's  collaborative partners  and may  restrict Conductus'  ability to
engage in certain areas of product development, manufacturing and marketing. See
"Business -- Strategic Alliances and Development Agreements."
 
    RAPID TECHNOLOGICAL CHANGE.  The field of superconductivity is characterized
by rapidly advancing technology. The future  success of the Company will  depend
in  large  part upon  its ability  to keep  pace with  advancing superconductive
technology, including  superconducting  materials and  processes,  and  industry
standards.  The Company has focused its  development efforts to date principally
on yttrium barium  copper oxide ("YBCO").  There can be  no assurance that  YBCO
will  ultimately prove  commercially competitive  against other  currently known
materials or materials that  may be discovered in  the future. The Company  will
have  to  continue  to develop  and  integrate  advances in  technology  for the
fabrication of electronic  circuits and  devices and  manufacture of  commercial
quantities  of its products. The  Company will also need  to continue to develop
and integrate advances in complementary technologies. There can be no  assurance
that the Company's development efforts will not be rendered obsolete by research
efforts  and technological advances made by  others or that materials other than
those currently  used by  Conductus will  not prove  more advantageous  for  the
commercialization of superconductive electronic products.
 
    INTENSE  COMPETITION.    The  market for  electronic  products  is intensely
competitive. Although the  market for superconductive  electronics currently  is
small  and in  the early stages  of development, Conductus  believes this market
will become intensely competitive if products with significant market  potential
are  successfully developed. A  number of large  American, Japanese and European
companies,  many  of  which  have  substantially  greater  financial  resources,
research  and development  staffs and  manufacturing and  marketing capabilities
than  the  Company,  are  engaged  in  programs  to  develop  and  commercialize
superconductive   electronic  technology  and  products.  A  number  of  smaller
companies  are  also  engaged  in   various  aspects  of  the  development   and
commercialization  of superconductive electronic products. Furthermore, academic
institutions, governmental  agencies  and  other  public  and  private  research
organizations  are engaged in development programs  that may lead to competitive
arrangements  for  commercializing   superconductive  electronic  products.   In
addition,  if the superconductor industry develops further, new competitors with
significantly greater  resources  are  likely to  enter  the  field.  Conductus'
ability  to  compete  successfully  will  require  it  to  develop  and maintain
technologically  advanced  products,   attract  and   retain  highly   qualified
personnel, obtain patent or other protection for its technology and products and
manufacture and market its
 
                                       6
<PAGE>
products,  either on its own  or with third parties.  The Company's inability to
compete successfully  would have  a  material adverse  effect on  the  Company's
business,   operating  results   and  financial  condition.   See  "Business  --
Competition."
 
    COMPETING TECHNOLOGIES.   The  Company's planned  products, if  successfully
developed,  will compete directly with other existing and subsequently developed
products  which   use  competing   technologies.  In   wireless   communications
applications,  there are  a number of  competing approaches  and technologies to
increase the  capacity  and improve  the  quality of  wireless  networks.  These
approaches  include  increasing the  number of  base stations,  increasing tower
heights, locating  filters and  amplifiers  at the  top  of antennas  and  using
advanced  antenna technology.  In healthcare imaging  and analysis applications,
alternative  approaches  and  technologies  in  magnetic  resonance  instruments
include  using  more powerful  magnets,  and improving  receiver  sensitivity by
refrigerating conventional copper receiver coils. In magnetic sensing instrument
applications, alternative  approaches  and  technologies  may  be  available  to
perform  functions addressable  by magnetic sensing  technology. Improvements in
existing alternative approaches or the development and introduction of competing
approaches or  technologies to  the Company's  potential products  could have  a
material  adverse  effect  on  the  Company's  business,  operating  results and
financial condition.  Failure of  the Company's  potential products  to  compete
successfully  with products using  competing technologies would  have a material
adverse effect  on  the  Company's business,  operating  results  and  financial
condition.
 
    UNCERTAINTY OF PATENTS AND PROPRIETARY RIGHTS; RISK OF
LITIGATION.   Conductus  has received  16 U.S.  patents and  one related foreign
patent with  unexpired terms  ranging from  15 to  18 years  and has  17  patent
applications  pending before the U.S. Patent and Trademark Office. International
counterparts of several  of these  issued patents or  pending applications  have
been  filed under  the Patent Cooperation  Treaty with a  number of applications
currently in  various countries  worldwide. The  Company will  continue to  file
other  U.S. and  key international patent  applications as part  of its business
strategy to protect technology it considers important to providing a competitive
market advantage for  its technologies but  there can be  no assurance that  its
applications  will result in issued patents.  The Company also relies upon trade
secrets, unpatented know-how, continuing technological innovation, employee  and
third-party non-disclosure agreements and the pursuit of licensing opportunities
in  order to develop and enhance its competitive position. The Company's efforts
to protect its proprietary rights may not be successful, however, in  preventing
their  misappropriation or ensuring  that these rights  will provide the Company
with a competitive advantage.  Additionally, certain of  the issued patents  and
patent  applications are  jointly owned  by the  Company and  third parties. Any
party has the right to license rights under such patents and applications, which
could result in Conductus not having exclusive control over such inventions.
 
    The  Company  believes  that,   since  the  discovery  of   high-temperature
superconductors  ("HTS") in 1986, several thousand patent applications have been
filed worldwide  and over  a thousand  patents  have been  granted in  the  U.S.
relating  to  superconductivity.  There  are  interference  proceedings  pending
regarding rights to inventions claimed in some of the applications. Accordingly,
the patent positions of companies using HTS technology, including Conductus, are
uncertain and involve  both complex legal  and factual questions.  Consequently,
there  is significant  risk that others,  including competitors  of the Company,
have obtained or will obtain patents relating to the Company's planned  products
or technology.
 
    A  patent issue  of particular importance  to the Company  relates to copper
oxides or "cuprates,"  that are used  to make HTS  products, including the  YBCO
compound  which is currently the basis  for the Company's business and products.
Conductus has neither obtained  any issued patents nor  has it filed any  patent
applications  covering the composition  of any cuprates  or other HTS materials.
However, several U.S. and  foreign patent applications filed  by IBM, AT&T,  the
University  of Houston,  the Naval  Research Laboratory  and others  are pending
regarding the composition of YBCO and  related HTS. See "Business --  Background
- --  Conductus  Approach."  The Company  understands  that several  of  such U.S.
applications are the subject of an interference proceeding currently pending  in
the  U.S. Patent and Trademark  Office (Interference No. 101,981). Additionally,
E. I. du Pont de Nemours & Co. ("DuPont") has notified Conductus that it is  the
exclusive  licensee of patents  issued in Israel, Sweden,  Taiwan and the United
Kingdom covering  the  composition  of YBCO  and  a  method for  using  YBCO  in
superconducting applications. DuPont has stated
 
                                       7
<PAGE>
that,  it is  interested in  sublicensing such  patents to  Conductus, and would
consider sublicensing to Conductus,  as they issue, any  other foreign and  U.S.
patent applications licensed to DuPont by the University of Houston. The Company
anticipates that it will be required to obtain a license to use YBCO from one or
more of these parties in order to continue to develop and sell products based on
YBCO.
 
    There  can be no assurance that the Company would able to obtain licenses to
patents covering  YBCO  compositions,  when  issued, or  to  any  other  patents
applicable  to the Company's business on  commercially reasonable terms. In such
an event,  the Company  could be  required to  expend significant  resources  to
develop  non-infringing  technology alternatives  or to  obtain licenses  to the
technology that  the  Company infringes  or  would  infringe. There  can  be  no
assurance  that the  Company would be  able to successfully  design around these
third party patents  or to obtain  licenses to technology  that it may  require.
Furthermore, there can be no assurance that the Company will not be obligated to
defend  itself at substantial cost against  allegations of infringement of third
party patents. An adverse outcome  in such a suit  could subject the Company  to
significant  liabilities to third parties, or require the Company to cease using
such technology. In  addition, aside from  the merits  of a claim,  the cost  of
defending  any  such suit  would  constitute a  major  financial burden  for the
Company that would  have a material  adverse effect on  the Company's  business,
operating results and financial condition. See "Business -- Patents, Proprietary
Technology and Trademarks."
 
    SUBSTANTIAL  FUTURE CAPITAL NEEDS.  The Company to date has received limited
revenues from product sales. The  development of the Company's planned  products
will require a commitment of substantial additional funds. Conductus anticipates
that  its existing available cash, together with the estimated net proceeds from
this offering, should be  adequate to fund the  Company's operations through  at
least  the end of 1998. The Company's future capital requirements will depend on
many factors,  including  continued progress  in  its research  and  development
programs,  the  magnitude of  these  programs, the  time  and costs  involved in
obtaining any required  regulatory approvals, the  costs involved in  preparing,
filing, prosecuting, maintaining and enforcing patents, successful completion of
technological,  manufacturing  and  market  requirements,  changes  in  existing
research relationships, the availability of funding under government  contracts,
the  ability of the Company to establish collaborative arrangements and the cost
of manufacturing  scale-up and  the amount  and timing  of future  revenues.  If
adequate  funds  are  not  available,  the Company  may  be  required  to delay,
scale-back or eliminate one or more of its research and development programs  or
obtain funds through arrangements with collaborative partners or others that may
require  the  Company to  relinquish rights  to certain  of its  technologies or
potential products that the Company would not otherwise relinquish. There can be
no assurance that additional financing will be available on acceptable terms  or
at  all,  if and  when required.  See "Management's  Discussion and  Analysis of
Financial  Condition  and  Results  of  Operations  --  Liquidity  and   Capital
Resources."
 
    LIMITED  COMMERCIAL MANUFACTURING  CAPABILITY.  Conductus  has established a
limited production facility.  To date,  Conductus has focused  primarily on  the
development   of  its  fabrication  processes  and  the  production  of  limited
quantities of  superconducting thin  films and  components. Although  Conductus'
processing  technology is  derived principally  from semiconductor manufacturing
technology, the fabrication  of HTS components  entails additional  difficulties
because  of  specific  properties  unique  to HTS  materials.  There  can  be no
assurance that Conductus can develop enhanced processing technology necessary to
develop more advanced  superconducting devices  and circuits,  that the  Company
will  be able to attain  commercial yields in the  future, that the Company will
not suffer  recurring  yield problems  caused  by mask  defects,  impurities  in
materials  and  other factors  or that  the Company  can expand  its processing,
production control,  assembly, testing  and  quality assurance  capabilities  to
produce  existing  or planned  superconductive  electronic products  in adequate
commercial  quantities.   The  Company's   failure   to  develop   an   adequate
manufacturing  capacity would  have a material  adverse effect  on the Company's
business,  operating  results   and  financial  condition.   See  "Business   --
Manufacturing."
 
    NEED  TO DEVELOP INFRASTRUCTURE TO SUPPORT COMMERCIALIZATION.  Conductus has
very  limited  experience  in  commercial  sales,  marketing  and  distribution.
Expanded manufacturing, sales, marketing and customer
 
                                       8
<PAGE>
service  capabilities are also needed. Although Conductus has been expanding its
expertise in these  areas, there can  be no assurance  that it will  be able  to
establish   adequate  sales,  marketing  and  distribution  capabilities  or  be
successful in gaining market acceptance for any of its potential products.
 
    LIMITED OUTLETS FOR CERTAIN PRODUCTS.   The market for NMR probes is  highly
concentrated,  with estimates that  approximately 90% of  the U.S. and worldwide
market is divided between Varian  Associates ("Varian") and Bruker  Instruments.
Although  the Company has worked closely with Varian to develop and commercially
introduce the Company's first probe subsystems,  there can be no assurance  that
Varian  will be successful in marketing the probes, that Varian will continue to
market the probes or that the Company will be able to market the probes  through
other  channels  should  distribution  through  Varian  prove  unsuccessful. See
"Business -- Strategic Alliances and Development Agreements."
 
    HIGH DEGREE OF DEPENDENCE UPON GOVERNMENT CONTRACTS.  A significant  portion
of  the Company's revenues has been derived  from contracts with agencies of the
U.S.  government.  The  Company's  revenue  from  government-related   contracts
represented approximately 85%, 77%, 82% and 78% of total revenue for the quarter
ended  March 31,  1996 and  for fiscal  1995, 1994  and 1993,  respectively. The
Company's contracts  involving the  U.S. government  are or  may be  subject  to
various  risks,  including: unilateral  termination for  the convenience  of the
government;  reduction  or  modification  in   the  event  of  changes  in   the
government's  requirements  or  budgetary constraints;  increased  or unexpected
costs  causing  losses  or  reduced  profits  under  fixed-price  contracts   or
unallowable  costs  under  cost  reimbursement  contracts;  risks  of  potential
disclosure of Conductus' confidential information to third parties; the  failure
or  inability  of  the  prime  contractor  to  perform  its  prime  contract  in
circumstances where Conductus is a subcontractor; the failure of the  government
to   exercise  options   provided  for   in  the   contracts;  the  government's
nonexclusive, royalty-free license to use  technology developed pursuant to  the
contracts  by  or on  behalf  of the  government  in certain  circumstances; and
exercise of "march-in" rights  by the government. March-in  rights refer to  the
right  of the  U.S. government  or government agency  to require  the Company to
license to third parties patented technology developed under contracts funded by
the government if the  contractor fails to continue  to develop the  technology.
The  programs in which  Conductus participates in many  cases extend for several
years, but  are normally  funded  on an  annual  basis. Although  revenues  from
government  contracts have increased in recent  years, there can be no assurance
that government contract revenues will grow  at historical rates or continue  at
historical  levels in  the future.  A reduction  in, or  discontinuance of, such
commitment or  of the  Company's participation  in such  programs would  have  a
material  adverse  effect  on  the  Company's  business,  operating  results and
financial condition. See "Business -- Government Contracts."
 
    GOVERNMENT REGULATIONS.   Some of  the Company's potential  products may  be
used  as subsystems in medical  devices, such as MRI  and NMR devices, which are
subject to extensive governmental  regulation in the U.S.  by the Food and  Drug
Administration  ("FDA")  and other  government  agencies. Regulation  of medical
devices outside the U.S.  varies widely from country  to country. The  clearance
and  approval process for both the FDA and foreign regulatory authorities can be
costly and time  consuming and the  Company will be  largely dependent upon  the
efforts of manufacturers of instruments that utilize the Company's subsystems to
obtain  necessary approvals. There  can be no  assurance that any  buyers of the
Company's  subsystems  will  be  able  to  obtain  any  necessary   governmental
approvals, or otherwise comply with applicable government regulations.
 
    In  addition,  in some  states,  a certificate  of  need ("CON")  or similar
regulatory approval is  required prior  to acquisition of  medical equipment  or
introduction  of  a  new  service  by  hospitals  or  healthcare  providers. CON
regulations limiting the number of new MRI machines or limiting the  acquisition
of  magnetoencephalography devices  could adversely  impact commercialization of
those  products,  whether  or  not  they  incorporate  superconducting  products
supplied by the Company.
 
    In  the communications area, the operation of cellular and PCS base stations
is regulated  in the  United  States by  the Federal  Communications  Commission
("FCC"). Base stations and equipment marketed for use therein must meet specific
technical  standards. The  Company's ability to  sell its  HTS filter subsystems
will depend upon  the ability  of base  station equipment  manufacturers and  of
cellular base station operators
 
                                       9
<PAGE>
to  obtain and retain the  necessary FCC approvals and  licenses. Any failure or
delay  of  base  station  manufacturers  or  operators  in  obtaining  necessary
approvals  could  have  a material  adverse  effect on  the  Company's business,
operating results and financial condition.
 
    ENVIRONMENTAL REGULATIONS.  The Company is  subject to a number of  federal,
state  and local governmental regulations related to the use, storage, discharge
and disposal of  toxic, volatile or  otherwise hazardous chemicals  used in  its
business.  Any failure to comply with present or future regulations could result
in fines being  imposed on the  Company and  the suspension of  production or  a
cessation  of  operations.  In  addition, such  regulations  could  restrict the
Company's ability  to expand  or could  require the  Company to  acquire  costly
equipment  or to incur  other significant expenses  to comply with environmental
regulations or to clean up prior discharges.
 
    ATTRACTION AND RETENTION OF KEY EMPLOYEES.  The Company is highly  dependent
upon  the efforts of  its senior management  and technical team,  as well as the
contributions of its Scientific Advisory Board. The loss of the services of  one
or  more  members of  the  senior management  and  technical team  or Scientific
Advisory  Board  could  impede  the  achievement  of  product  development   and
commercialization  objectives. Due  to the  specialized technical  nature of the
Company's business, the  Company is also  highly dependent upon  its ability  to
attract  and retain qualified technical  and key management personnel. Moreover,
the Company is targeting its  products towards markets, such as  communications,
healthcare  and instrumentation, that require substantial industry knowledge and
expertise.  Although  the  Company  has  engaged  consultants  with  substantial
expertise  in its targeted markets, the  Company currently has limited expertise
in these areas and it is essential to attract qualified personnel with expertise
in manufacturing, marketing, sales and support in each of its targeted  markets.
There  is  intense  competition for  qualified  personnel  in the  areas  of the
Company's activities and there can be no assurance that the Company will be able
to continue  to  attract  and  retain  qualified  personnel  necessary  for  the
development of its business. See "Business -- Employees."
 
    VOLATILITY  OF STOCK  PRICE.  There  has been significant  volatility in the
market price of  securities of  technology companies,  particularly those  that,
like the Company, are still primarily engaged in product development activities.
See  "Price  Range  of  Common  Stock  and  Dividend  Policy."  Factors  such as
technology and product announcements by the Company or its competitors, disputes
relating to patents and proprietary rights and variations in quarterly operating
results may have a significant impact on  the market price of the Common  Stock.
In  addition, the securities markets have  experienced volatility which is often
unrelated to the  operating performance  of particular companies.  In the  past,
following  periods of volatility in the  market price of a company's securities,
securities class  action lawsuits  have been  instituted against  a company.  If
brought,  such litigation could have a  material adverse effect on the Company's
business, results of operations and financial condition.
 
    EFFECT OF  CERTAIN  CHARTER  PROVISIONS; ANTITAKEOVER  EFFECTS  OF  RESTATED
CERTIFICATE  OF INCORPORATION  AND BYLAW  PROVISIONS AND  OF DELAWARE  LAW.  The
Board of  Directors  has  the authority  to  issue  up to  1,000,000  shares  of
Preferred  Stock and to determine the price, rights, preferences, privileges and
restrictions, including voting rights, of those shares without any further  vote
or action by the stockholders. The rights of the holders of Common Stock will be
subject  to, and may be adversely affected by,  the rights of the holders of any
Preferred Stock that  may be  issued in the  future. The  issuance of  Preferred
Stock  could have the  effect of making it  more difficult for  a third party to
acquire a majority of the outstanding  voting stock of the Company. The  Company
has  no  present plans  to  issue shares  of  Preferred Stock.  Further, certain
provisions of the Company's Restated Certificate of Incorporation and Bylaws and
of Delaware corporate law  could delay or make  more difficult a merger,  tender
offer  or proxy contest involving the Company. Among other things, the Company's
Restated Certificate of  Incorporation does  not permit stockholders  to act  by
written  consent. See "Description of Capital  Stock -- Preferred Stock" and "--
Antitakeover Effects of Provisions of the Restated Certificate of  Incorporation
and Bylaws and of Delaware Law."
 
    SHARES   ELIGIBLE  FOR  FUTURE  SALE;  REGISTRATION  RIGHTS.    Sales  of  a
substantial number of shares of Common Stock in the public market following this
offering could adversely affect the market price for the Company's Common Stock.
The number of shares of Common Stock available for sale in the public market  is
limited  by  restrictions under  the  Securities Act  of  1933, as  amended (the
"Securities Act"), and lock-up agreements
 
                                       10
<PAGE>
under which the  holders of such  shares have  agreed not to  sell or  otherwise
dispose  of any of their shares for a period of 90 days after the effective date
of  this  offering  without  the   prior  written  consent  of  Tucker   Anthony
Incorporated.  However, Tucker Anthony Incorporated  may, in its sole discretion
and at any time  without notice, release  all or any  portion of the  securities
subject  to  lock-up agreements.  As a  result of  these restrictions,  based on
shares outstanding as of March 31,  1996, 5,308,724 shares of Common Stock  will
be  freely  tradable  without  restriction  or  further  registration  under the
Securities Act, unless purchased by "affiliates" of the Company, as that term is
defined in Rule 144 under the Securities Act, including the 1,000,000 shares  of
Common  Stock  offered  hereby,  1,500,000  shares  registered  pursuant  to the
Company's initial public  offering and  2,808,724 shares that  have either  been
registered on Form S-8 or are restricted securities that can be sold pursuant to
Rule  144(k) or Rule 701  under the Securities Act.  A total of 1,424,265 shares
are held by affiliates of the Company and will be eligible for sale on the  date
of this Prospectus subject to the restrictions of Rule 144 ("Affiliate Shares").
All   of  the  Affiliate  Shares  will   be  subject  to  lock-up  arrangements.
Furthermore, upon  expiration  of  the lock-up  agreements  referred  to  above,
holders  of  approximately  2,017,000 shares  of  Common Stock  and  warrants to
purchase 33,534 shares of Common Stock will be entitled to certain  registration
rights  with  respect  to such  shares.  If  such holders,  by  exercising their
registration rights, cause a large number of shares to be registered and sold in
the public market, the sale of such shares could have a material adverse  effect
on  the market price  for the Company's  Common Stock and  would have a material
adverse effect the  Company's ability  to raise  additional capital  when or  if
required.  See "Shares  Eligible for  Future Sale"  and "Description  of Capital
Stock -- Registration Rights."
 
    ABSENCE OF DIVIDENDS.   The Company has never  paid cash dividends and  does
not  anticipate paying  cash dividends  on the  Common Stock  in the foreseeable
future. See "Price Range of Common Stock and Dividend Policy."
 
    DILUTION.  The public offering price  will be substantially higher than  the
book  value  per  share of  the  currently outstanding  Common  Stock. Investors
purchasing  shares  in  this  offering  will  therefore  suffer  immediate   and
substantial  dilution. See "Dilution."  In addition, the exercise  of any of the
currently outstanding  warrants  or  stock  options would  likely  result  in  a
dilution of the value of the Common Stock. Moreover, the Company may at any time
in  the  future  sell  additional  securities  and/or  rights  to  purchase such
securities,  grant  additional  warrants,  stock  options  or  other  forms   of
equity-based incentive compensation to the Company's management and/or employees
to  attract and  retain such  personnel or in  connection with  the obtaining of
non-equity financing,  such  as  debt or  leasing  arrangements  accompanied  by
warrants  to purchase  equity securities  of the  Company. Any  of these actions
would have a dilutive effect upon the holders of the Common Stock.

                                USE OF PROCEEDS
 
    The net proceeds to  the Company from  the sale of  the 1,000,000 shares  of
Common  Stock offered hereby are estimated  to be $13,700,000, assuming a public
offering price of $15.00 per share and after deducting the underwriting discount
and estimated offering expenses.
 
    The Company anticipates that a significant portion of the net proceeds  will
be used for working capital required to support expansion of its operations, and
that  approximately  $2,500,000 will  be  spent on  new  manufacturing equipment
during the next 24 months. The Company also expects to use a portion of the  net
proceeds  to repay all amounts outstanding under  its bank line of credit, which
the Company anticipates  may total approximately  $500,000 immediately prior  to
the  closing. As of March  31, 1996, there were  no borrowings under this credit
facility which provides for borrowing up to  the lesser of $2,000,000 or 75%  of
eligible receivables, bears interest at prime plus 0.50% and expires in February
1997.  The Company  also anticipates using  approximately $2,500,000  of the net
proceeds for  the  development  of its  superconducting  products.  The  Company
anticipates  that  the balance  of the  net  proceeds will  be added  to working
capital  and  used  for  general  corporate  purposes,  including  expansion  of
manufacturing, sales and marketing infrastructure. The Company may also consider
using the net proceeds for the acquisition of complementary businesses, products
or  technologies.  However, the  Company currently  has  no specific  plans with
respect to  any such  acquisition. Pending  such uses,  the Company  intends  to
invest  the  net  proceeds  in  short-term,  investment-grade,  interest-bearing
securities.

                                    DILUTION
 
    As of  March  31,  1996, the  Company  had  a net  tangible  book  value  of
$4,430,000,  or approximately $0.77 per share  of outstanding Common Stock. "Net
tangible book value" represents the amount  of total tangible assets less  total
liabilities.  Without taking into account any  other changes in the net tangible
book value after March 31, 1996, other than to give effect to the receipt by the
Company of the net proceeds from the sale of the shares of Common Stock  offered
by  the Company hereby at an assumed  public offering price of $15.00 per share,
the pro forma net tangible book value of the Company as of March 31, 1996  would
have been $18,130,000, or $2.69 per share. This represents an immediate increase
in  net tangible book value  of $1.92 per share  to existing stockholders and an
immediate dilution in net tangible book value of $12.31 per share to  purchasers
of  Common Stock  in the offering  ("New Investors"). Dilution  is determined by
subtracting net tangible book value per share after the offering from the amount
of cash  paid by  a New  Investor for  a share  of Common  Stock. New  Investors
participating  in this offering will incur immediate, substantial dilution. This
is illustrated in the following table:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THIS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS SECTION AND OTHER PARTS OF THIS PROSPECTUS CONTAIN FORWARD-LOOKING
STATEMENTS  THAT INVOLVE RISKS  AND UNCERTAINTIES. THE  COMPANY'S ACTUAL RESULTS
AND THE  TIMING OF  CERTAIN EVENTS  MAY DIFFER  SIGNIFICANTLY FROM  THE  RESULTS
DISCUSSED  IN  THE  FORWARD-LOOKING  STATEMENTS.  FACTORS  THAT  COULD  CAUSE OR
CONTRIBUTE TO SUCH DIFFERENCES INCLUDE, BUT ARE NOT LIMITED TO, THOSE  DISCUSSED
BELOW AND IN "RISK FACTORS" AND "BUSINESS."
 
OVERVIEW
 
    Conductus  develops,  manufactures,  and markets  electronic  components and
systems  based  on  superconductors  for  applications  in  the  communications,
healthcare  and instrumentation markets. In May 1993, Conductus acquired Tristan
Technologies ("Tristan"), a San Diego, California-based company founded in 1991,
that designed, manufactured  and sold large-scale  magnetic sensing systems  and
instrumentation. In June 1994, Tristan became the Conductus Instrument & Systems
Division.   As  of  March   31,  1996,  Conductus   had  accumulated  losses  of
approximately $25,602,000 and expects to incur additional losses at least during
1996 due to the Company's planned  expansion of operations. Conductus, alone  or
with  collaborative partners, must  successfully develop, manufacture, introduce
and market its potential products  in order to achieve profitability.  Conductus
does  not expect  to recognize  meaningful product  sales until  it successfully
develops and commercializes superconductive  components, systems and  subsystems
that address significant market needs. See "Risk Factors."
 
RESULTS OF OPERATIONS
 
  QUARTERS ENDED MARCH 31, 1996 AND 1995
 
    The  Company's total revenues increased to  $2,611,000 for the first quarter
of 1996, a 30% increase over the  $2,013,000 for the same period in 1995.  Total
revenues  consisted  primarily  of contract  revenue  and, to  a  lesser extent,
product sales. Revenues under U.S. government research and development contracts
increased to $2,214,000 in the period from $1,643,000 in the same period in  the
prior  year  and represented  85%  and 82%  of  total revenue  for  the periods,
respectively. At  March  31, 1996,  Conductus  has approximately  $5,577,000  in
contracts   and  grants  and  $7,760,000  in  awards  for  future  research  and
development. The recognition of revenue and receipt of payment pursuant to these
contracts and awards are subject to numerous risks.
 
    Revenues from sales of large-scale superconducting magnetic systems, SQUIDs,
HTS thin films and other products increased to $397,000 in the first quarter  of
1996,  an 8% increase over  the $369,000 of product sales  in same period in the
prior year. The increase in  the first quarter of  1996 is primarily related  to
magnetic  sensing  systems  and instruments.  The  large-scale  magnetic sensing
systems have large unit prices and are sold in low volumes, and thus significant
fluctuations in sales  of these  systems may occur  between quarters.  Conductus
does  not expect  to recognize significant  product sales  until it successfully
develops and commercializes  superconductive components  and systems  addressing
significant markets.
 
    Cost  of products increased to $256,000 for the first quarter of 1996, a 54%
increase over the $166,000 for the same period in 1995. The increase in cost  of
products  was  directly  related  to  increased  product  sales.  Gross  margins
decreased to 36%  in the  first quarter  of 1996  from an  unusually high  gross
margin  of  55% in  the  comparable period  for  the prior  year.  The reduction
reflects changes  in commercial  product  mix between  the two  quarters.  Large
systems margins may vary based on options included and may have downward impacts
on  overall margins.  Costs of  contract revenues  are included  in research and
development expenses.
 
    Research and  development  expenses increased  to  $2,743,000 in  the  first
quarter  of 1996, a 6% increase over the $2,577,000 for the same period in 1995.
The increase is directly related to the development of
 
                                       16
<PAGE>
commercial products, particularly in  both communications markets, cellular  and
PCS.  The contract  cost portion  increased ratably  from period  to period. The
Company expects  to  continue  to incur  significant  research  and  development
expenses as it seeks to develop additional products.
 
    Selling, general and administrative expenses increased to $1,007,000 for the
first  quarter of 1996 from  $827,000 for the same  quarter in 1995. These costs
increased in 1996  compared to the  prior quarter due  to increased sales  costs
associated  with the representative network  for magnetic sensing and instrument
products  and  the  increasing  size  of  the  Company's  operations.  Headcount
increased to 105 at March 31, 1996 from 101 at March 31, 1995. To the extent the
Company  increases sales of commercial products,  there will be additional sales
and marketing costs over those incurred in the first quarter of 1996.
 
    Interest income was $27,000 in the first quarter of 1996 compared to $80,000
during the same quarter in 1995. The primary reason for the decrease was a lower
amount of cash and investments which was partly offset by higher interest rates.
Interest charges  increased on  the Company's  debt financing  to  approximately
$36,000 in the first quarter of 1996 compared to $24,000 for the same quarter in
1995,  due  to higher  outstanding debt  balances  incurred to  purchase capital
equipment.
 
    As a result of incurring losses, the Company has not incurred any income tax
liability. The  Company  has  established  a  valuation  allowance  against  its
deferred tax assets and reviews this allowance on a periodic basis. At such time
that  the Company believes that it is more likely than not that the deferred tax
asset will be realized, the valuation allowance will be reduced.
 
  YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
    The results of  operations of the  Company for the  year ended December  31,
1993  do  not  include  the  results  of  operations  of  Tristan  prior  to its
acquisition by Conductus on May 28, 1993.
 
    Total revenues increased to $10,582,000 in 1995 from $8,636,000 in 1994  and
$6,479,000 in 1993. Total revenues consist primarily of contract revenue and, to
a  lesser extent, product  sales. Revenues for  1993 do not  include revenues of
Tristan before May 28, 1993, which were $602,000 for the period. Revenues  under
U.S.  government research and  development contracts increased  to $8,148,000 in
1995 from $7,048,000 in 1994 and $5,070,000 in 1993 and represented 77%, 82% and
78% of  total revenue  in 1995,  1994 and  1993, respectively.  The increase  in
contract  revenues  during  1995 was  largely  attributable to  the  addition of
several new multi-year government contracts. Revenues under these new  contracts
are  expected to offset planned declines  in revenues from contracts approaching
the end of their terms. The  Company had $3,930,000 and $2,751,000 in  contracts
and grants and $9,228,000 and $5,410,000 in awards from U.S. government agencies
as  of December 31,  1995 and 1994, respectively.  Conductus does not anticipate
that government contract revenues will grow  at historical rates in the  future.
The  recognition of revenue  and receipt of payment  pursuant to these contracts
and awards are  subject to numerous  risks. See  Note 12 of  Notes to  Financial
Statements.
 
    Revenue  from sales of large-scale superconductive magnetic sensing systems,
SQUIDs, HTS thin films and other  products increased to $2,433,000 in 1995  from
$1,588,000 in 1994 and $1,409,000 in 1993, primarily due to an increase in sales
of magnetic sensing systems and instruments introduced late in 1994 and in 1995.
The  large-scale magnetic sensing systems have large unit prices and are sold in
low volumes, and  thus, the timing  of individual sales  of these systems  could
result  in significant period to period  fluctuations in revenues. Product sales
for  1993  do  not   include  $602,000  realized  by   Tristan  from  sales   of
superconducting magnetic systems before May 28, 1993.
 
    Cost  of product  sales were $1,430,000,  $975,000 and  $1,175,000 for 1995,
1994 and 1993, respectively. Gross margins were 41%, 39% and 17% for 1995,  1994
and  1993,  respectively. Gross  margins increased  in 1995  and 1994  over 1993
primarily due to lower margins in 1993 on initial system products which included
startup costs. Startup costs on the  introduction of new products also  affected
margins  in  1995 but,  due  to broader  product lines,  the  effect was  not as
substantial.

    The Company's research and development expenses, including cost of  contract
revenues, increased to $9,819,000 in 1995 from $9,201,000 in 1994 and $7,080,000
in  1993, representing  65%, 68%  and 67%,  of total  operating expenses  in the
respective years. The increases in 1995  and 1994 reflected the increase in  the
Company's  overall research and development  activities, and emphasis on efforts
in  communications  and  healthcare.  Research  and  development  includes  both
externally  and  internally  funded  projects.  Externally  funded  research and
development programs,  primarily  under  contracts with  agencies  of  the  U.S.
government,  accounted for approximately $9,176,000  of research and development
expenses in  1995,  $8,717,000  in  1994  and  $6,500,000  in  1993,  reflecting
increased  government  contract  and research  activity  throughout  the period.
Current levels  of  expenditure are  expected  to continue  for  development  of
commercial products, particularly in the communication and healthcare areas. Net
expenses  do not include  a non-recurring charge of  $705,000 resulting from the
acquisition of  Tristan  in 1993.  The  Company  expects to  continue  to  incur
significant  research and development expenses and  these expenses are likely to
increase as it seeks to develop additional products.
 
    Selling, general  and  administrative expenses  increased  to  approximately
$3,756,000  in 1995 from $3,336,000  in 1994 and $1,589,000  in 1993 or 25%, 25%
and 15%, respectively, of total operating expenses in 1995, 1994 and 1993. These
costs increased in 1995 and 1994 compared  to 1993 due to the increased size  of
the  Company as  a result of  the acquisition of  Tristan, significant headcount
additions and increasing  sales and  marketing activities.  Total headcount  has
increased  to 99 at  December 31, 1995  from 96 at  December 31, 1994  and 64 at
December 31, 1993. Increases  in 1995 over 1994  also include the selling  costs
associated  with expanding  the Company's representative  network of independent
distributors of magnetic sensing and instrumentation products. Included in  1994
expenses  is a non-recurring charge of  approximately $230,000 for severance and
recruitment  expenses  associated   with  management   changes  and   additions.
Additionally,  the Company expects  sales and marketing  expenses to continue to
increase as it begins to market commercial products.
 
    The Company's total operating expenses increased to $15,005,000 in 1995 from
$13,513,000 in 1994 and $10,549,000 in 1993. Operating expenses for 1993 include
a non-recurring charge of $705,000 associated with purchased technology from the
acquisition of Tristan.
 
    Losses from operations were $4,423,000, $4,876,000 and $4,070,000 for  1995,
1994  and  1993, respectively.  Excluding the  non-recurring charge  of $705,000
resulting from the  acquisition of Tristan,  the loss from  operations for  1993
would  have been $3,365,000.  The decreasing loss  in 1995 compared  to 1994 was
primarily related  to planned  increases  in revenues  offset by  headcount  and
contract  costs  as  the  Company moved  toward  developing  and commercializing
products.
 
    Interest income from cash equivalents and investments were $249,000 in 1995,
$344,000 in  1994 and  $166,000 in  1993. The  primary reasons  for the  changes
between   years  were  the  levels  of  cash  equivalents  and  investments,  as
approximately $13 million was received in the Company's initial public  offering
in  August 1993, and thereafter there have been reductions to support operations
through 1994 and 1995.
 
    Interest charges were $156,000, $56,000 and $176,000 in 1995, 1994 and 1993,
respectively. Interest  charges related  to the  Company's equipment  term  loan
financing  which commenced in September 1994  were reflected for the entire year
compared to a minimal amount in 1994. The decrease in interest charges from 1993
to 1994 was primarily  due to the  maturing of portions  of the three  equipment
lease lines. As of year end, only two lease line obligations remain at a reduced
level  due to  maturities. Additionally, in  1993 the  Company incurred interest
charges of $86,000 related to its bridge loan financing.
 
    As a result of incurring losses, the Company has not incurred any income tax
liability. The  Company  has  established  a  valuation  allowance  against  its
deferred tax assets and reviews this allowance on a periodic basis. At such time
that  the Company believes that it is more likely than not that the deferred tax
asset will be realized, the valuation allowance will be reduced.
 
    Conductus does not believe that inflation  has had a material effect on  its
financial condition or results of operations during the past three fiscal years.
However,  there can  be no  assurance that  the Company's  business will  not be
affected by inflation in the future.

    During March 1995, the  Financial Accounting Standards Board  ("FASB")issued
Statement  No. 121, "Accounting for the  Impairment of Long-Lived Assets and for
Long-Lived Assets  to  Be  Disposed  Of" ("SFAS  121").  SFAS  121  will  become
effective  for  the Company's  year ending  December 31,  1996. The  Company has
studied the implications of SFAS 121 and, based on its initial evaluation,  does
not  expect it to have a material impact on the Company's financial condition or
results of operations.
 
    During October  1995, the  FASB issued  Statement No.  123, "Accounting  for
Stock-Based  Compensation"  ("SFAS 123")  which established  a fair  value based
method of accounting for stock-based compensation plans and requires  additional
disclosures  for  those companies  who  elect not  to  adopt the  new  method of
accounting. The Company will  continue to account  for employee purchase  rights
and  stock options  under APB  Opinion No. 25,  "Accounting for  Stock Issued to
Employees." SFAS 123 disclosures will be effective for the Company's year ending
December 31, 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As of March  31, 1996, the  Company's aggregate cash,  cash equivalents  and
short-term  and long-term investments totaled  $2,110,000 compared to $3,153,000
as of December 31, 1995 and $7,538,000 as of December 31, 1994. The Company  has
financed  its operations  since inception  primarily through  $13,251,000 in net
proceeds from  its initial  public  offering of  Common  Stock in  August  1993,
$14,645,000  raised  in  private financings,  $25,529,000  from  U.S. government
contracts, $4,823,000 in aggregate borrowings under three equipment lease  lines
of credit and equipment term loan and $3,183,000 in interest income.
 
    Net  cash used in  operations was $4,625,000,  $3,578,000 and $2,795,000 for
1995, 1994 and 1993, respectively. The  increase in net cash used in  operations
in  1995  over  the prior  years  was due  primarily  to increased  size  of the
Company's operations  including headcount  and other  related costs,  which  was
partially offset by increased revenues. A significant portion of the increase is
related  to increased receivables  on government contracts  and prepaid expenses
and other current assets, offset to some extent by increased accounts  payables.
The  prior  year was  also affected  by the  non-recurring charge  for purchased
technology of $705,000.  The Company  anticipates that  its accounts  receivable
from  revenues under  U.S. government  contracts and  product sales,  as well as
inventories, will increase during 1996. Such increases will result in the use of
additional cash in operating activities.
 
    Net cash used in operations was  $1,061,000 for the first quarter period  of
1996. The net cash used in operating activities in the first quarter of 1996 was
primarily  due to operating losses and to a lesser extent increases in inventory
which were partially offset  by reductions in  accounts receivables and  prepaid
expenses  and  other  current  assets  and  other  related  costs.  The  Company
anticipates that its  accounts receivable  from revenues  under U.S.  government
contracts  and product sales, as well  as inventories, may increase during 1996.
Any such  increases will  result in  the  use of  additional cash  in  operating
activities.
 
    During  1995 and 1994, net cash of $2,670,000 and $1,743,000 was provided by
investing activities  from  the reduction  in  investments partially  offset  by
purchases  of property and  equipment. During 1993, net  cash of $10,458,000 was
used in  investing  activities  from  funding received  on  the  initial  public
offering.  Purchases  of  property and  equipment  in 1995  were  $1,568,000, an
increase of $342,000 over  the prior year  primarily reflecting expenditures  to
expand  the  Company's  facilities  in  1995  which  approximated  $625,000  and
increased equipment needs for research and development and operations.
 
    Net cash from investing activities was  $1,129,000 for the first quarter  of
1996.  Net  cash  was  provided by  net  reductions  in  short-term investments,
partially offset by purchases of property and equipment.
 
    Net cash from financing activities was $1,722,000, $269,000 and  $14,933,000
in  1995, 1994 and 1993, respectively. Net cash provided by financing activities
in 1995 and 1994 was primarily  due to borrowings under the Company's  equipment
term  loan  offset by  principal payments  under  capital lease  obligations and
proceeds from issuance of  shares under the 1994  Employee Stock Purchase  Plan.
Net  cash provided  by financing  activities in  1993 was  primarily due  to the
Company's initial public offering in August 1993, its
 
                                       19
<PAGE>
private placement in June 1993, and bridge loan financings which were  converted
into equity in the private placement, offset by principal payments under capital
lease  obligations,  equipment  term  loan  and  debt  assumed  in  the  Tristan
acquisition.
 
    Net cash from  financing activities was  $241,000 for the  first quarter  of
1996, primarily due to borrowings under the Company's equipment term loan offset
by principal payments under capital lease obligations.
 
    Conductus  anticipates that its existing available  cash, its line of credit
of $2,000,000 and term  loan facility for fixed  assets of $1,000,000 should  be
adequate  to fund the Company's operations through at least the end of 1996. See
Note 10 of Notes to Financial Statements and "Use of Proceeds." There can be  no
assurance  that additional funding, if required, will be available on acceptable
terms or at all.
 
    The actual amount of the  Company's future capital requirements will  depend
on  many factors, including  continued progress in  its research and development
programs, the  magnitude of  these  programs, the  time  and costs  involved  in
obtaining  any required regulatory  approvals, the costs  involved in preparing,
filing, prosecuting, maintaining and enforcing patents, successful completion of
technological, manufacturing  and marketing  requirements, changes  in  existing
research  relationships, the availability of funding under government contracts,
the ability of the Company to establish collaborative arrangements and the  cost
of  manufacturing scale-up and the amount of future revenues. The development of
the Company's potential products will require a commitment of substantial  funds
to  conduct  further  research  and development  and  testing  of  its potential
products,  to  establish  commercial-scale  manufacturing  and  to  market   any
resulting  products. The Company expects to  use significant amounts of cash for
capital equipment and support operations until product revenues can contribute.

    Conductus  develops,  manufactures  and  markets  electronic  components and
subsystems based on  superconductors. The unique  properties of  superconductors
provide the basis for electronic products with significant potential performance
advantages  over  products  based  on competing  materials  such  as  copper and
semiconductors. Depending on the application, these advantages include  enhanced
sensitivity,  efficiency, speed and operating frequency as well as reduced power
consumption, size, weight and cost.
 
    Conductus  is  currently   focusing  significant   development  efforts   on
applications    for   superconductors   in    communications,   healthcare   and
instrumentation. In the  communications market, Conductus  is developing  filter
subsystems  for  cellular  and  personal  communication  services  ("PCS")  base
stations. These  superconducting  filter subsystems  could  provide  significant
benefits  in  base  station  performance  and  reduce  the  size  of  the filter
components. In  the  healthcare  market, Conductus  is  developing  and  testing
prototype  superconductive  receiver subsystems  for  several types  of magnetic
resonance   instruments,   including   nuclear   magnetic   resonance    ("NMR")
spectrometers  and  magnetic  resonance imaging  ("MRI")  scanners.  The Company
currently manufactures and  sells a limited  number of superconducting  receiver
probe subsystems for NMR spectrometers. In the instrumentation market, Conductus
currently  manufactures and sells superconducting sensors called Superconducting
Quantum Interference Devices ("SQUIDs"), which  can be used to build  electronic
instruments  that detect and  precisely locate extremely  weak magnetic signals.
Conductus is also marketing  and developing a  variety of electronic  components
and instruments based on SQUID technology.
 
BACKGROUND
 
  SUPERCONDUCTORS
 
    Superconductors  are materials that have the ability to transport electrical
energy with  little or  no loss  when cooled  to a  "critical" temperature.  The
intrinsic properties of superconductors are unique in nature and offer potential
performance  benefits  to  electrical  and  electronic  systems.  These  include
low-loss  signal  transmission,  extreme  magnetic  sensitivity  and   efficient
high-speed  switching. When electrical currents flow through ordinary materials,
they encounter resistance which consumes energy by converting electrical  energy
into heat energy. Depending on whether direct or alternating current is applied,
superconductors  have  the  ability  to  transport  electrical  current  with no
resistance at all or with only a tiny fraction (typically less than one percent)
of what is found in the best conventional conductors. This property is extremely
beneficial in electronic components whose increased efficiency leads to enhanced
signal strength,  improved  signal resolution  and  reduced component  size  and
weight.  Other intrinsic properties of superconductors enable the fabrication of
unique electronic devices, including  high-speed electronic switches and  ultra-
sensitive magnetic sensors.
 
    From  1911,  when superconductivity  was first  discovered, until  1986, the
critical temperatures  for  all  known  superconductors  did  not  exceed  23  K
(-418  DEG. F). As a result, superconductivity was not widely used in commercial
applications because of the high cost and complexities associated with  reaching
and  maintaining such low temperatures. In  1986, a new class of superconducting
materials,  referred  to  as   high-temperature  superconductors  ("HTS"),   was
discovered  having critical temperatures  above 77 K (-320  DEG. F), the boiling
point of liquid nitrogen. These  high critical temperatures allow HTS  materials
to  be  cooled  to  a  superconducting state  using  liquid  nitrogen,  which is
inexpensive and relatively easy  to use, or  using relatively simple  mechanical
refrigerators.  Conductus believes that  this ability to  obtain the benefits of
superconducting technology  at more  easily achieved  temperatures enables  much
broader commercial applications.
 
                                       21
<PAGE>
  CONDUCTUS' APPROACH
 
    Conductus  develops,  manufactures  and  markets  superconductive electronic
devices and  components  using  thin-film technology  based  upon  the  material
yttrium  barium copper oxide ("YBCO"),  which the Company has  judged to be best
suited for electronic applications.  Conductus combines what  it believes to  be
the world's most advanced YBCO thin-film technology with expertise in electronic
device   and  component  design,  analog  and  digital  electronic  engineering,
cryogenic packaging, mechanical  engineering and  system integration.  Conductus
believes  that  systems  containing superconductive  electronic  technology will
offer performance that is unavailable from competing technology, will reduce the
costs of performing desired functions, or, in many cases, do both.
 
    CHOICE OF MATERIAL.  Although  a number of high-temperature  superconductors
have  been identified,  Conductus has focused  upon the development  of YBCO for
electronic applications.  See  "Risk  Factors  --  Uncertainty  of  Patents  and
Proprietary Rights; Risk of Litigation." YBCO is the only HTS material for which
there  has  been both  significant development  and successful  demonstration of
multilayer technology, i.e., the use  of multiple thin-film materials  deposited
one  upon  another.  Conductus  believes  that  such  multilayer  structures are
important for many electronic components and devices, where they can be used for
better film quality and stability  and enhanced device functionality.  Conductus
has  developed  several  proprietary  processes  for  producing  YBCO  and other
thin-film materials as  well as for  fabricating superconducting components  and
devices. These processes include thin-film growth, photolithography, etching and
other standard procedures used in the manufacture of electronic devices.
 
    THIN-FILM  EXPERTISE.  Conductus produces superconducting components using a
thin-film fabrication  approach.  The  Company's  superconductive  circuits  and
components  are fabricated on the surface  of wafers using vapor-phase thin-film
growth  and  standard  circuit  processing  steps  similar  to  those  used   to
manufacture   semiconductor  devices.   Furthermore,  the   fabrication  of  HTS
components and circuits entails specialized processes, which are the subject  of
Conductus'  patents or proprietary know-how, in  order for HTS materials such as
YBCO  to  exhibit  desirable  superconducting  properties.  Conductus,  in  many
instances,  has performed pioneering work in materials, processes and structures
based on thin-film  superconductive technology, and  has developed processes  it
believes  are capable of routinely producing a  variety of high quality films in
quantity for several applications, including multiple layer thin-film  materials
suitable  for  more complex  devices  and components.  Compared  to "thick-film"
approaches and ceramic  fabrication techniques,  the Company  believes that  the
thin-film  approach is more  versatile and provides  more compact components and
that the superconducting properties  of the materials produced  in this way  are
superior.
 
    FOCUS  ON  COMPLETE  SOLUTIONS.    Conductus  believes  that superconductive
component technology can best be provided to customers in the form of integrated
subsystems that incorporate the  components, additional electronic circuits  and
devices,  and the self-contained refrigeration  equipment and packaging required
to maintain the reduced temperatures necessary to sustain superconductivity. For
this reason,  in  addition  to  its  thin-film  expertise,  Conductus  has  also
established  significant expertise  and know-how in  areas that  it believes are
necessary  for  the  commercial   development  of  superconductive   technology,
including  electronic device and component design, analog and digital electronic
engineering, cryogenic packaging (including cryoelectronics, thermal management,
vacuum  engineering  and   cryocoolers),  mechanical   engineering  and   system
integration.  Conductus  seeks  to  make  the  presence  of  superconductive and
cryogenic components an entirely internal feature of its products that  requires
no  special expertise or skill on the  part of the user. By skillful integration
of the  refrigeration  system  into its  communications  filter  subsystem,  for
example,  and by selection  of a refrigeration  approach with proven durability,
Conductus believes  that  its  products  can be  easily  accommodated  and  well
accepted  by end  users. Similarly,  the Company's NMR  probe is  designed to be
readily installed into existing  NMR systems in essentially  the same manner  as
conventional  probes. The Company believes that  providing its technology at the
subsystem level to  system manufacturers in  specific markets will  allow it  to
rapidly and efficiently expand both its product line and its customer base.

    SIGNIFICANT   COMPANY  MILESTONES.     Since   establishing  its  laboratory
facilities in 1989, Conductus  has made significant  and continuous progress  in
establishing  the enabling technologies  for its target  applications. The table

BUSINESS AND DEVELOPMENT STRATEGY
 
    Conductus'   strategy   for   developing,   manufacturing   and    marketing
superconductive electronics products includes the following key elements:
 
    MAINTAIN TECHNOLOGY LEADERSHIP.  Conductus has devoted significant resources
to  developing proprietary HTS thin-film manufacturing and process technologies.
Based  on  publicly  available  information,  the  Company  believes  that   its
technologies  are  more  advanced  than those  of  other  companies  or research
laboratories. The  Company  has  successfully developed  and  marketed  products
including  single- and  multilayer YBCO films,  superconducting NMR spectroscopy
probes and  SQUID sensors  and systems.  Conductus has  utilized its  technology
skills  to develop filters, low-noise  amplifiers, radio-frequency receivers and
other devices. Conductus has also established significant expertise and know-how
in areas essential to product commercialization, including electronic device and
component  design,  analog   and  digital   electronic  engineering,   cryogenic
packaging, mechanical engineering and system integration. Conductus has received
16  U.S. patents and one  related foreign patent and  has 17 patent applications
pending in the U.S. and related  patents pending in other countries relating  to
various aspects of its technologies.
 
    COMMERCIALIZE   PRODUCTS  WITH  SIGNIFICANT  MARKET  POTENTIAL.    Conductus
believes that the largest  potential near-term markets for  superconductor-based
products  exist  in  wireless  communications  and  healthcare  and  is actively
developing HTS component-based subsystems for  these markets. See table on  page
26. In the cellular market, Conductus has completed laboratory and initial field
tests  of its low-noise receiver filter subsystems for base stations and expects
to commence commercial sales in late 1996. In the emerging PCS market, Conductus
is developing integrated transceiver  subsystems incorporating HTS transmit  and
receive filters, cryocooled low-noise amplifiers and refrigeration equipment. In
the healthcare market, Conductus has developed and currently sells several types
of  probe  subsystems  for NMR  spectrometers  on  an OEM  basis  to  Varian. In
addition, the Company  plans to  develop other spectrometer  probe types  during
1996  as well as demonstrate prototype receiver coil subsystems for MRI machines
in late 1996.
 
    LEVERAGE  STRATEGIC  ALLIANCES.    Conductus'  strategy  is  to  enter  into
collaborative arrangements with market leaders in its target markets in order to
allow  the  Company to  focus primarily  on  the development  of superconductive
components and subsystems for  use in products in  these markets. Conductus  has
entered  into joint development agreements with Lucent Technologies, Inc. in PCS
communications, Varian Associates in NMR spectroscopy and Siemens AG in MRI.  It
has  also entered into agreements whose  primary focus is technology development
for a range  of applications, including  agreements with TRW,  Inc. ("TRW")  and
Northrop-Grumman Corporation (originally with Westinghouse Electric Corporation)
for  development  of digital  electronics  technology; and  the High-temperature
Superconductor Thin-film  Manufacturing  Alliance ("HTMA")  for  development  of
commercial,  thin-film HTS manufacturing  processes. Additionally, Conductus has
funded its development programs and  enhanced its development and  manufacturing
resources  by establishing  collaborative arrangements  with corporate partners,
government agencies and public and private research institutions. Since 1991,  a
significant  portion of the Company's research  and development program has been
funded by U.S. government  agencies in the form  of grants and contract  awards.
See  "Risk  Factors --  Extensive Reliance  on Collaborative  Relationships" and
"Business Strategic Alliances and Development Agreements."
 
    PROVIDE  COMPLETE  SOLUTIONS.    Conductus  believes  that   superconductive
component technology can best be provided to customers in the form of integrated
subsystems  that incorporate the components,  additional electronic circuits and
devices, and the self-contained  refrigeration equipment and packaging  required
to  maintain  the  operating  temperatures  necessary  for  the  superconductive
components.  Conductus  seeks  to  make  the  presence  of  superconductive  and
cryogenic  components an entirely internal feature of its products that requires
no special expertise or skill on the part of the user. The Company believes that
providing its  technology at  the  subsystem level  to system  manufacturers  in
specific  markets will allow it to most  rapidly and efficiently expand both its
product line and its customer base.
 
    DEVELOP COMMERCIAL INFRASTRUCTURE.  Conductus is building the manufacturing,
sales and  marketing infrastructure  it  believes is  necessary to  support  the
commercialization  of its products in  target markets. This includes development
of thin-film deposition techniques suitable for volume manufacture,  acquisition
and
 
                                       24
<PAGE>
build-out  of  manufacturing  and  assembly  areas,  hiring  of  employees  with
significant marketing experience in key product areas and expansion of its sales
team. The  Company's  sales and  marketing  strategy is  to  use  manufacturers'
representatives  supplemented by a small direct  sales organization for sales of
its laboratory  instrument  products and  to  rely  primarily on  OEMs  for  its
subsystem  products  for  the  communications,  healthcare  and  instrumentation
markets.
 
    The following table sets forth the key target markets for which Conductus is
developing superconductive products and the development status of those products
as of May 1996.

CONDUCTUS' TARGET APPLICATIONS
 
    The  unique properties of  superconductors provide the  basis for electronic
products with significant potential  performance advantages over products  based
on competing materials such as copper and semiconductors. Conductus is currently
focusing  significant development  efforts on  products for  applications in the
communications, healthcare  and instrumentation  markets for  which it  believes
there  is the greatest near-term market  potential. Conductus is also developing
additional technology for longer-term  applications such as high-speed  circuits
for the communications market and NMR microscopes for the healthcare market.
 
  COMMUNICATIONS
 
    Cellular  and  PCS communications  systems  use radio  frequency  signals to
establish communications between customers  using portable or mobile  telephones
and base stations operated by service providers. Cellular telephone networks are
divided  into specific  coverage areas  called cells, each  of which  has a base
station for  sending and  receiving voice  and other  communications within  the
cell.  The  base  station contains  electronic  equipment required  to  send and
receive radio signals. In setting up a base station, the service provider  seeks
to  install  equipment with  sufficient  sensitivity within  the  frequency band
assigned to it to handle communications with the lowest power handsets over  its
entire  geographical area and  with sufficient selectivity  to avoid interfering
signals from adjacent frequency bands. Filters within these base stations select
frequencies  within   the  operators'   assigned  bands   and  reject   unwanted
frequencies.  Amplifiers boost the strength of signals  coming in and out of the
base station. The operator's  assigned frequency range  is then allocated  using
one of several schemes to provide telephone service to multiple subscribers. The
capacity  of the system depends upon the  number of effective channels, that is,
channels whose  signal quality  is sufficient  to satisfy  customer demands  for
clear communications.
 
    Cellular  base stations currently face a number of operating problems. These
include signal  interference caused  by multiple  communications channels,  poor
signal  quality  resulting from  lower-power,  handheld telephones  and strained
capacity due  to the  growing demand  for cellular  service. The  advent of  PCS
technology  will place  additional demands on  the performance  of wireless base
stations and upon the size of the hardware therein. Power losses resulting  from
the use of components made from conventional conductors have limited the ability
of   the   industry  to   address  these   problems.  Conductus   believes  that
superconductive filters used in conjunction with cryogenically-cooled amplifiers
have the potential to offer solutions to several operating problems in  cellular
base  stations  as  well as  to  provide  solutions to  anticipated  problems in
forthcoming PCS base stations.
 
    CELLULAR MARKET.   According to  industry reports,  there are  approximately
20,000  installed  cellular  base  stations  in  the  United  States  and 40,000
worldwide, with growth estimated at 6,000 annually through the year 2000. Of the
U.S. installed base, Conductus  estimates approximately 4,000  are located in  a
rural  environment. The  present cellular  communications network,  operating at
frequencies near 850 MHz,  was established at a  time when the typical  cellular
telephone  was a  mobile unit  capable of  transmitting up  to 3  watts of radio
frequency power and the total number  of subscribers was relatively low.  Today,
portable  handsets  that  transmit  only 0.6  watts  are  increasingly replacing
higher-power mobile telephones, thereby decreasing the effective receiving range
of existing base stations. As a result,  in rural areas where base stations  are
widely separated, current cellular customers can experience dropped calls due to
"dead  zones" in coverage. At the same  time, the increasing demand for cellular
service in urban  areas has led  to the  utilization by service  providers of  a
greater  number  of  channels  within their  allotted  frequency  bands, thereby
increasing the incidence of interference.
 
    In rural areas, where the primary  problem is base station range,  solutions
that  increase the strength of the received  signal or decrease the system noise
level can provide  enhanced reception, and  thus reduce the  occurrence of  dead
zones.  One solution, which entails significant costs, is to increase the number
of base stations and thereby reduce the required range for each station. Another
solution, which  is  potentially  more  economical, is  to  enhance  the  signal
reception and noise filtering capabilities of existing base stations. Approaches
to  enhance the  performance of  existing base  stations include  increasing the
height of towers or  locating filters and  amplifiers at the  tops of towers  to
reduce    the   loss    of   electrical    energy   as    the   signals   travel
 
                                       26
<PAGE>
through cables from  the antenna to  the receiver. Each  of these solutions  has
shortcomings  with  respect  to such  issues  as cost,  servicing  logistics and
ultimate performance. Accordingly, rural  systems operators could  significantly
benefit  from a system  that provides significantly  improved filtering and very
low noise amplification at reasonable cost.
 
    In urban  areas, the  high density  of cellular  users creates  problems  of
interference  and system capacity. In every area, there are two cellular service
providers, each allotted their own operating band within the frequency spectrum.
Near the edges of each provider's operating frequency range, the performance  of
cellular  systems can be hampered by interference from the competing carrier and
from a  variety of  other signal  sources. Carriers  can attempt  to avoid  this
interference  by  not using  channels  at the  edges  of their  operating bands,
however this diminishes system capacity. Interference is also addressed by using
highly selective filters in  the base station receiver.  The ideal filter  would
filter  out all  signals outside  the targeted  operating band  without reducing
signal strength  inside the  band. Filters  are made  more selective  by  adding
additional  resonators or  "poles" to  the filter.  However, in  filters made of
conventional materials, adding additional poles introduces more energy loss  and
thereby   reduces  the  strength  of  the  desired  signals.  For  this  reason,
conventional filters generally do not incorporate more than eight or nine poles,
thus achieving  only  a  certain  level  of  selectivity.  With  superconducting
materials,  which exhibit extremely  low energy loss,  filters can be fabricated
with a higher number of poles, thereby increasing filter selectivity.
 
    PCS MARKET.   PCS is a  newer urban-based communication  system designed  to
provide  wireless  telephone  service  utilizing radio  frequency  signals  in a
frequency band near 2  GHz. This all-digital system  will be designed to  handle
both  voice and data transmissions, including  features such as Internet access.
Although it utilizes the  same basic building blocks  as a cellular system,  the
higher  operating frequency of PCS compared with the cellular network limits the
range of  its signal  transmission.  Because of  this  limited range  of  signal
transmission  and because  PCS has  no installed base  in the  U.S., third party
sources estimate that  the forthcoming PCS  buildout will result  in 70,000  new
installed base stations throughout the U.S. by the year 2000.
 
    The projected large number and primarily urban location of PCS base stations
drive the needs for equipment cost and size reduction. However, signal losses in
base  station components such as filters, antennas and cables are exacerbated by
higher frequency operation. Conventional  receiver components limit  sensitivity
and  therefore base  station range. Conventional  filters tend  to be physically
large and proposed PCS base station  architectures call for the use of  multiple
filters  in each station. Collectively, these  issues present a difficult set of
requirements for the designers of forthcoming PCS base station equipment.
 
    CONDUCTUS' SOLUTIONS.  Conductus believes  that the performance of  cellular
base stations and PCS base stations could be improved significantly by using HTS
components in both their receivers and their transmitters. Communication filters
made  using thin-film  superconductor technology  have the  potential to provide
extraordinary  frequency  selectivity  while  maintaining  excellent  efficiency
because of their inherent low insertion losses. On the receiver side, the use of
superconducting filters along with cryogenically-cooled low-noise amplifiers has
the potential to lower the noise figure of the receiver and thereby increase its
sensitivity.  Increased sensitivity translates into increased range for the base
station which could be utilized to improve the performance of existing  stations
or to allow fewer base stations to serve a new geographic area. In addition, HTS
filters  with enhanced selectivity over conventional designs could significantly
reduce signal interference in base station receivers with minimal signal loss.
 
    In the cellular market,  Conductus is focusing  on development of  low-noise
receiver  subsystems  for  rural  base stations  that  incorporate  HTS filters,
cryocooled low-noise amplifiers and refrigeration equipment into a  rack-mounted
package. Initial laboratory and field tests have demonstrated the ability of the
subsystem to increase receiver sensitivity, thereby increasing the range of base
stations  as well  as their  overall performance.  As a  result, by  using these
filter systems, cellular  service providers  in rural  environments may  require
fewer  base stations in  order to serve  a given geographic  area. Initial field
tests with these filter systems completed in early 1996 show range expansions of
20% to  60%. Conductus  expects  that the  subsystem will  undergo  increasingly
rigorous  testing  during 1996,  leading to  potential  deliveries of  the first
commercial units for retrofit use in rural base stations in late 1996. Conductus
anticipates that its commercial receiver
 
                                       27
<PAGE>
subsystems will be  provided in  a variety  of configurations  depending on  the
requirements  of the specific base station into which it will be inserted. While
the Company has  demonstrated functionality in  its prototype units,  additional
engineering   will  be  required  to  complete  the  development  of  commercial
communications subsystems. See "Risk Factors -- Limited Commercial Manufacturing
Capabilities."
 
    Base stations avoid the transmission of unwanted and interfering  distortion
signals  by the use of costly ultra-linear (extremely low distortion) amplifiers
in their  transmitters. For  the PCS  market, Conductus  believes that  low-loss
superconducting transmit filters offer the potential to "clean up" the output of
lower-quality amplifiers by removing unwanted signals at a lower overall cost to
the  base station operator. Conductus' work on  transmit filters has been a part
of the  activities of  the Consortium  for Superconductor  Electronics  wireless
program,  which  primarily involves  Conductus,  Lucent Bell  Labs,  MIT Lincoln
Laboratories and CTI-Cryogenics, a division of Helix Technology Corporation.
 
    Conductus is developing  an integrated  transceiver subsystem  for PCS  base
stations  consisting  of  HTS receiver  filters,  cryogenically-cooled low-noise
amplifiers and  HTS  transmit filters  that  potentially may  provide  increased
range,  increased call  capacity, reduced  interference between  bands, improved
call  quality  and  reduced  size  compared  to  subsystems  using  conventional
technology.  Additionally,  the HTS  components utilized  in the  subsystem have
permitted the inclusion of  as many as  19 poles, compared to  eight or nine  in
conventional  filters,  which results  in significant  selectivity enhancements.
Conductus intends to work  with PCS system manufacturers,  such as Lucent,  with
the  goal  of  designing superconductive  filter  subsystems into  new  PCS base
stations. The first field test of  Conductus' initial prototype of the  receiver
portion  of  the system  has been  conducted with  Lucent. Conductus  expects to
conduct  additional  tests  of  increasingly  complex  prototypes  with   Lucent
throughout  1996 and 1997 and does  not anticipate first commercial sales before
late 1997 or early 1998.
 
    FUTURE  APPLICATIONS.    Pursuant   to  government-sponsored  research   and
development  programs, Conductus is exploring the application of superconductive
electronic technology to problems  in high-speed, high-bandwidth  communications
switching.  The high-speed,  low-power properties of  Josephson junctions, which
are active  switching devices  made from  superconductors, could  be applied  to
communications  systems  to significantly  improve  data transmission  rates and
reduce system  power requirements  and costs.  These devices  are several  times
faster  than the fastest semiconductor transistor and consume thousands of times
less power. Josephson  junction circuit  technology is  in the  early stages  of
development,  and significant  additional advancements  will be  required before
superconductive products incorporating this technology could become available.
 
  HEALTHCARE
 
    Instruments based  on  NMR technology  use  the characteristic  response  of
matter  to electromagnetic fields  to determine the  structure and properties of
chemical and biological  specimens. In  these instruments,  a powerful  magnetic
field magnetizes atoms in the sample being studied, radio-frequency pulses cause
the atoms to emit characteristic signals and sensitive radio-frequency receivers
are  used  to  detect  these signals.  Existing  magnetic  resonance instruments
contain radio-frequency receivers that use specialized copper coils to sense the
signals from the object being studied. The principal applications of NMR are  in
spectrometers,  which are  used for analyzing  the composition  and structure of
complex chemical  compounds, and  in MRI  scanners, which  are used  to  provide
detailed  images of  the human body  without invasive procedures  or exposure to
harmful radiation, such as x-rays.
 
    For  both  of  these  instruments,  the  signal-to-noise  ratio   ultimately
determines  the sensitivity  of the  instrument. A  higher signal-to-noise ratio
results in better data quality and a reduction in the amount of time required to
obtain  the   data.  There   are  two   basic  approaches   to  increasing   the
signal-to-noise  ratio  of  the  instruments:  increasing  the  signal  or field
strength by  using a  more powerful  magnet, or  increasing the  sensitivity  by
reducing inherent noise levels in the receiver. Increasing field strength can be
prohibitively
 
                                       28
<PAGE>
expensive.  On the  other hand,  significant gains  in receiver  sensitivity are
difficult to achieve using conventional technology. HTS technology offers  three
potential  benefits for these healthcare  imaging and analysis instruments: much
greater instrument sensitivity, much  faster data acquisition  time and, in  the
case of NMR spectroscopy systems, the ability to study smaller amounts of costly
samples.
 
    NMR  SPECTROMETERS.   NMR spectroscopy  is a  well-established technique for
chemical analysis that enables the user to determine the structures of even very
complex proteins and large  molecules such as those  used in the development  of
pharmaceuticals.  A  conventional  NMR spectrometer  includes  a superconducting
magnet to supply a  powerful magnetic field and  a copper or other  conventional
metal receiver coil to detect the signals from the sample.
 
    With conventional NMR technology, major increases in sensitivity can only be
obtained  with  disproportionate  increases in  cost  associated  with providing
increasingly powerful  magnets. Some  large  magnet systems  cost well  over  $1
million.  One alternative  to increasing the  field strength is  to increase the
sensitivity of the receiver.  However, conventional coil design  is at a  fairly
mature   stage  and   significant  further  improvements   in  sensitivity  from
modification of current receiver technology are unlikely. Another alternative is
to reduce the temperature of  conventional receiver components to near  absolute
zero,  in order to  reduce resistance and decrease  noise, but the refrigeration
necessary to  reach  the  required  temperatures  would  be  costlier  and  more
elaborate  than is needed for HTS probes. Such cold conventional metal receivers
have not been made commercially available.
 
    CONDUCTUS' SOLUTION.  Conductus has shown that the use of HTS receiver coils
in spectrometers  dramatically  improves  the  sensitivity  of  the  instrument.
Compared  to existing  receivers based  on specialized  copper coils, Conductus'
low-loss superconducting receiver coils significantly enhance probe  performance
by  improving the signal-to-noise ratio, which leads to either improved chemical
sensitivity or faster chemical measurements. As a result, users can examine less
sample material and still obtain the  same or more information than is  possible
using conventional technology. For this application, Conductus' probe technology
has   demonstrated   a  300-to-400%   signal-to-noise  ratio   improvement  over
conventional probes enabling a three-to-four  fold reduction in sample size  for
the  same  analysis time  or  up to  a  16-fold increase  in  sample throughput.
Conductus is  currently working  with Varian  to develop  a family  of  low-loss
superconductor receiver coils for use as probes in NMR spectrometers to meet the
demand  for high sensitivity analysis. Conductus  introduced its first NMR probe
products in March 1996, pursuant to  an OEM arrangement with Varian.  Currently,
Conductus  is manufacturing and selling through Varian two NMR probe types, each
of which is available in two frequencies. The Company anticipates introducing  a
third NMR probe type for commercial sale by the end of 1996.
 
    MRI.    Magnetic  resonance  imaging  is  an  important  diagnostic  medical
technique that provides detailed images of internal organs and structures within
the body without invasive procedures or exposure to harmful radiation. Important
applications include imaging soft tissues,  diagnosing certain brain and  spinal
cord  disorders  and  diagnosing joint  and  muscle  injuries. The  cost  of MRI
machines is  significant, with  prices often  in the  $1-3 million  range.  More
recently,  "low-field" and "mid-field" MRI machines have become available. These
machines have the advantage of being less confining to the patient and are  less
expensive,  but provide  significantly poorer  images than  high-field machines.
Government and healthcare provider cost containment initiatives are discouraging
the use of larger magnets for MRI. As cost controls have become more  pervasive,
the  majority  of  new  installations  have  been  of  less  costly, lower-field
machines.
 
    CONDUCTUS' SOLUTION.  Conductus has shown that the use of HTS receiver coils
can significantly improve the signal-to-noise  ratio in low-field MRI  machines,
potentially  allowing them to produce an image similar in quality to that of the
more  expensive  machines.  The  development  of  higher-performance   low-field
machines  may lead  to the  use of MRI  in a  wider range  of diagnostic imaging
applications, such  as routine  screening for  breast cancer.  In January  1996,
Conductus  entered into  a non-exclusive agreement  with Siemens  to develop HTS
receiver coil subsystems for a Siemens'  low-field MRI machine. The Company  has
also  received support from DARPA to  develop superconducting technology for MRI
breast  cancer  screening  in  collaboration  with  researchers  from   Stanford
University.
 
                                       29
<PAGE>
    FUTURE   APPLICATIONS.    HTS  receiver  technology   can  be  used  in  NMR
microscopes, which are  essentially high-resolution MRI  machines for  examining
small  objects in high  detail. Biological specimens  such as pathology samples,
which are currently sliced, stained and examined with optical microscopes, could
be placed whole in the imager and a complete three-dimensional data set could be
constructed. The pathologist  could have  the computer  slice the  image in  any
plane,  which is not  possible using the current  techniques, even with computer
assistance, because  of the  dramatic  and variable  shrinkage of  the  samples.
Presently,  NMR microscopy  is only  a research tool  because the  use of copper
receiver coils can require data collection times of one to two days to obtain an
acceptable image. The enhancement in  signal-to-noise ratio provided by HTS  and
cryoelectronic  technologies could reduce this data  collection time to a matter
of minutes. Conductus is developing receiver subsystems for this application  in
collaboration  with Duke University  under government contract  funding from the
National Institutes of Health.
 
  INSTRUMENTATION
 
    Superconductive magnetic  sensors known  as SQUIDs  are used  in  electronic
instruments to detect signals thousands of times smaller than can be detected by
conventional  magnetometers.  With appropriate  control electronics,  SQUIDs can
discern magnetic  signals one  hundred billion  times smaller  than the  earth's
magnetic   field.  A  number  of   different  types  of  instruments,  including
specialized laboratory  equipment, non-destructive  test equipment,  geophysical
surveying   instruments  and   advanced  medical   diagnostic  instruments,  can
potentially utilize magnetic sensors  to detect and  locate magnetic signals  of
interest.
 
    Magnetic  sensors are  used in  some circumstances  to locate  oil and other
mineral deposits. In this application, SQUID technology offers the advantage  of
portability  by  virtue of  the  small size  of  its sensors  compared  to bulky
conventional copper coils used as magnetometers. SQUID sensors can also be  used
to  detect electrical currents as well  as any intrinsic magnetism in materials.
As a result, they can potentially be used in a variety of instruments to inspect
and analyze materials and  structures on the basis  of magnetic signatures  that
cannot  be effectively measured using  competing technologies. These instruments
can measure materials  that are hidden  or submerged, such  as mines or  storage
drums;  detect flaws  in metallic structures,  such as  components of buildings,
nuclear power plants or airplanes, without physically invading or contacting the
structure; and  measure  electrical  currents  in,  for  example,  semiconductor
integrated circuits.
 
    SQUID  sensors can also detect electrical  impulses in the heart without the
use of electrodes  or other  contacts to  the patient  required by  conventional
EKGs,  using a technique called  magnetocardiography ("MCG"). Conductus believes
that MCG potentially may require far less time and effort from medical personnel
than electrocardiography  and therefore  reduce the  cost of  obtaining  cardiac
diagnostic  information. For example, MCG  could become a significant diagnostic
tool for disorders caused by cardiac arrhythmias (i.e., irregular heart beats).
 
    Improving the sensitivity of magnetic sensor technology in general, as  well
as  providing HTS versions of SQUID sensors  in particular, has the potential to
significantly improve the performance of several existing instruments as well as
enable magnetic sensing technology to be used for important new applications.
 
    CONDUCTUS' SOLUTION.  Conductus currently manufactures and sells SQUIDs  and
laboratory  instruments  based  on  SQUIDs and  is  developing  additional SQUID
sensors, electronics  and  complete  sensing subsystems  for  customers  in  the
geophysical, non-destructive evaluation and medical markets. Conductus' standard
products  include magnetic sensing  components sold under  the tradenames "iMAG"
and "Mr. SQUID"  and a  complete magnetometer  system sold  under the  tradename
"xMAG."  List prices  for complete iMAG  systems generally range  from $7,000 to
over $40,000  depending on  the configuration.  Mr. SQUID  has a  list price  of
approximately $2,000. List prices for complete xMAG systems generally range from
$87,000 to over $140,000 depending on the configuration.
 
    Conductus  has also  built and sold  limited numbers  of custom multichannel
low-temperature superconducting ("LTS") SQUID  systems for non-destructive  test
applications.  While Conductus manufactures some of its instrumentation products
using well-established LTS  materials, the  Company believes that  the cost  and
 
                                       30
<PAGE>
operating  difficulties  associated with  using liquid  helium or  other complex
refrigeration techniques  required  to cool  LTS  materials have  limited  their
commercial  potential. Conductus believes that the portability and relative ease
of use inherent in HTS SQUID technology greatly enhances its utility in multiple
applications.
 
    While historically the  Company's sales  have been  primarily to  laboratory
customers, Conductus believes that the greatest opportunities for growth for its
magnetic  sensing products will be with OEM customers for specific applications.
Currently, Conductus  is developing  HTS  geophysical systems  under  government
contracts  from two different  agencies and is working  with Geometrics, Inc., a
manufacturer  of  geophysical  surveying   equipment,  to  develop  and   market
commercial  instruments for these  applications. Conductus is  also working with
researchers at Kanazawa Institute of Technology in Japan to develop  SQUID-based
instruments  for seismic studies.  Conductus has also  sold sensors, electronics
and cryogenic vessels to customers developing biomedical applications of SQUIDs.
 
STRATEGIC ALLIANCES AND DEVELOPMENT AGREEMENTS
 
    Conductus  is  party  to  a   number  of  collaborative  arrangements   with
corporations and research institutions with respect to the research, development
and  marketing of certain of its  potential products. Conductus evaluates, on an
ongoing basis, potential collaborative relationships and intends to continue  to
pursue   such   relationships.  The   Company's   future  success   will  depend
significantly on its collaborative arrangements with third parties. There can be
no assurance  that these  arrangements will  result in  commercially  successful
products.   See   "Risk   Factors  --   Extensive   Reliance   on  Collaborative
Relationships."
 
    LUCENT TECHNOLOGIES,  INC.    Conductus  and Lucent  entered  into  a  joint
development  and licensing  agreement in  April 1996,  under which  Conductus is
developing a superconductive  transceiver filter subsystem  for the PCS  market.
Both  Conductus  and Lucent  are to  provide technical  support to  the program.
Initial tests  of a  prototype of  the receiver  portion of  the subsystem  were
conducted  in  April 1996.  Each party  will retain  rights to  the intellectual
property  it  develops  under  the  program,  subject  to  certain  nonexclusive
licensing rights of the other party, and jointly developed intellectual property
will be jointly owned.
 
    VARIAN  ASSOCIATES.  Conductus  and Varian entered  into a joint development
and  licensing  agreement  in  1994,  under  which  they  jointly  developed   a
superconducting probe for NMR instruments for high-resolution spectroscopy. Both
Conductus and Varian provided technical support to the program, and each retains
rights  to  intellectual property  it developed  under  the program,  subject to
certain nonexclusive licensing rights of  the other party. The program  resulted
in  the  commercial introduction,  in March  1996,  of probes  incorporating HTS
receiver subsystems manufactured by  the Company and  sold by Varian.  Conductus
and  Varian currently are negotiating a  sales agreement under which Varian will
likely have a period  of exclusivity from the  date of commercial  introduction.
Conductus  and Varian  continue to  cooperate in  the development  of additional
probes for NMR spectroscopy.
 
    SIEMENS AG.  Conductus is  developing a general-purpose superconducting  MRI
receiver  coil for  a Siemens'  low-field MRI  system under  a joint development
agreement effective  December  1, 1995.  Under  that agreement,  Conductus  will
design  a coil and  test it on  Siemens' instruments, while  Siemens will assist
Conductus  by  providing   information  and  access   to  instrumentation.   All
intellectual   property  rights  will  remain  with  the  party  developing  the
intellectual property, and jointly developed property will be jointly owned.
 
    CTI-CRYOGENICS.    Conductus  and   CTI-Cryogenics,  a  division  of   Helix
Technology  Corporation,  entered into  a  collaboration agreement  in September
1995, under which CTI will work with Conductus to design interfaces between  CTI
cryocoolers and Conductus subsystems.
 
    HIGH TEMPERATURE SUPERCONDUCTOR THIN-FILM MANUFACTURING ALLIANCE.  Conductus
is  a  member  of  the  HTMA,  which  was  formed  in  October  1995  to develop
cost-effective manufacturing  methods for  YBCO thin-films  for  radio-frequency
applications,  establish  industry  standards  and  provide  second-sourcing and
technology transfer among the  companies under a program  funded in part by  the
Department   of   Defense   Advanced   Research   Projects   Agency   ("DARPA").
Superconductor Technologies, Inc. ("STI") is  the other principal member of  the
HTMA.  Other  members  include  Stanford  University  and  the  Georgia Research
 
                                       31
<PAGE>
Corporation, Focused Research, Microelectronic Control and Sensing Incorporated,
IBIS and  BDM Federal.  Under  the HTMA,  each party  will  have access  to  the
technology of the other party that is developed under the program.
 
    KANAZAWA INSTITUTE OF TECHNOLOGY.  In September 1995, Conductus entered into
an  OEM  agreement with  Kanazawa Institute  of  Technology ("KIT")  under which
Conductus is to be  KIT's exclusive supplier  of LTS and HTS  SQUIDs for use  in
instruments  that it is developing. KIT intends that its initial product will be
for seismology. Conductus  has received an  initial order for  LTS SQUIDs  under
this  agreement.  The agreement  contains no  minimum purchase  requirement, and
there can  be  no  assurance  that KIT  will  successfully  develop  and  market
instruments  using  Conductus'  SQUID  products  or,  if  it  does  develop such
products, that a significant market will exist for those products.
 
    GEOMETRICS.   Conductus  is working  with  Geometrics, Inc.,  a  geophysical
instrumentation  company, under two government  contracts to develop SQUID-based
instruments for geophysical exploration. If  successful, the project could  lead
to the development of commercial geophysical instruments incorporating Conductus
SQUIDs and SQUID electronics.
 
RESEARCH AND DEVELOPMENT; GOVERNMENT CONTRACTS
 
    The  Company's research and  development expenses in  the three months ended
March 31,  1996,  and  fiscal  years 1995,  1994  and  1993  were  approximately
$2,743,000,  $9,819,000,  $9,201,000  and  $7,080,000,  respectively. Externally
funded  research  and  development  programs,  primarily  under  contracts  with
agencies  of  the  U.S.  government,  accounted  for  approximately  $2,214,000,
$9,176,000, $8,717,000  and $6,500,000  of these  expenses in  the three  months
ended  March 31, 1996, and  fiscal years 1995, 1994  and 1993, respectively. The
Company's revenue  from government-related  contracts represented  approximately
85%, 77%, 82% and 78% of total revenue for the three months ended March 31, 1996
and  fiscal years 1995, 1994 and  1993, respectively. Conductus believes that it
will continue to  be heavily dependent  on U.S. government  contracts to fund  a
significant  portion  of its  research and  development programs.  The Company's
strategy is  to fund  a significant  portion of  its research  and  development,
particularly  for wireless communications  and digital electronics applications,
through contracts with agencies  of the U.S. government.  As of March 31,  1996,
the  Company had received aggregate awards  since its inception of approximately
$38,944,000 from U.S. government  agencies, including approximately  $25,607,000
recognized  as revenue by the Company  through March 31, 1996, and approximately
$7,760,000 in awards for which it  has not yet entered into research  contracts.
As of March 31, 1996, Conductus had approximately $5,577,000 under existing U.S.
government  contracts which provide that most of the research and development is
to be performed in the next 12 months. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Results of Operations."

    The Company's contracts involving the U.S. government are or may be  subject
to   numerous  risks.  These  risks  include:  unilateral  termination  for  the
convenience of the government; reduction or modification in the event of changes
in  the  government's  requirements  or  budgetary  constraints;  increased   or
unexpected  costs causing losses or  reduced profits under fixed-price contracts
or unallowable  costs under  cost reimbursement  contracts; risks  of  potential
disclosure  of Conductus' confidential information to third parties; the failure
or  inability  of  the  prime  contractor  to  perform  its  prime  contract  in
circumstances where Conductus is a sub-contractor; the failure of the government
to   exercise  options   provided  for   in  the   contracts;  the  government's
nonexclusive, royalty-free license to use  technology developed pursuant to  the
contracts  by  or on  behalf  of the  government  in certain  circumstances; and
exercise of "march-in" rights  by the government. March-in  rights refer to  the
right  of the  U.S. government  or government agency  to require  the Company to
license patented technology developed under  contracts funded by the  government
if  the contractor  fails to  continue to  develop the  technology. In addition,
there can be no assurance that the U.S. government will continue its  commitment
to  programs  to  which  the  Company's  development  projects  are  applicable,
particularly in light of recent legislative initiatives to reduce the funding of
various U.S. government agencies and programs,  or that the Company can  compete
successfully  to obtain funding pursuant to  such programs. See "Risk Factors --
High Degree of Dependence Upon Government Contracts."
 
PATENTS, PROPRIETARY TECHNOLOGY AND TRADEMARKS
 
    Conductus has received 16 U.S. patents and one related foreign patent  which
have  unexpired terms ranging from 15 to 18 years and has 17 patent applications
pending before the U.S. Patent and  Trademark Office. One of those patents,  for
an  MRI coil, is  currently involved in  an interference proceeding  in the U.S.
Patent and Trademark Office. See "Legal Proceedings." International counterparts
of several of these pending applications or issued patents have been filed under
the Patent Cooperation Treaty with a number of applications currently pending in
various  countries  worldwide.  These  patents  and  patent  applications  cover
Conductus  processes and products  in many aspects of  its business. The Company
will continue to file  other U.S. and key  international patent applications  as
part  of its business  strategy to protect technology  it considers important to
providing a competitive market advantage for  its technologies but there can  be
no  assurance that its  applications will result in  issued patents. The Company
also relies upon  trade secrets, unpatented  know-how, continuing  technological
innovation, employee and third-party nondisclosure agreements and the pursuit of
licensing  opportunities  in  order  to  develop  and  maintain  its competitive
position.

The Company's efforts to protect its  proprietary rights may not be  successful,
prevent  their misappropriation  or ensure  that these  rights will  provide the
Company with  a  competitive  advantage. Additionally,  certain  of  the  issued
patents  and  patent applications  are jointly  owned by  the Company  and third
parties. Any  party has  the right  to  license rights  under such  patents  and
applications,  which could result in Conductus not having exclusive control over
such inventions.
 
    The Company  believes that,  since the  discovery of  HTS in  1986,  several
thousand  patent  applications have  been filed  worldwide  and over  a thousand
patents have been granted in the  U.S. relating to superconductivity. There  are
interference  proceedings pending regarding rights to inventions claimed in some
of the applications. Accordingly,  the patent positions  of companies using  HTS
technology,  including Conductus, are  uncertain and involve  both complex legal
and factual  questions. Consequently,  there is  significant risk  that  others,
including  competitors  of the  Company, have  obtained  or will  obtain patents
relating to the Company's planned products or technology.
 
    A patent issue  of particular importance  to the Company  relates to  copper
oxides  or  "cuprates," that  are  used to  make  HTS products,  including YBCO.
Conductus has neither obtained  any issued patents nor  has it filed any  patent
applications  covering the composition  of any cuprates  or other HTS materials.
However, several U.S.  and foreign patent  applications, including  applications
filed by IBM, AT&T, the University of Houston, the Naval Research Laboratory and
others,  are pending  that cover  the composition of  YBCO and  related HTS. See
"Business -- Background -- Conductus Approach." The Company understands that  at
least  several  of such  U.S. applications  are the  subject of  an interference
proceeding  currently  pending   in  the  U.S.   Patent  and  Trademark   Office
(Interference  No.  101,981).  Additionally, E.  I.  du  Pont de  Nemours  & Co.
("DuPont") has notified Conductus that it  is the exclusive licensee of  patents
issued in Israel, Sweden, Taiwan and the United Kingdom covering the composition
of  YBCO and a method for using YBCO in superconducting applications. Dupont has
stated that it  is interested  in sublicensing  such patents  to Conductus,  and
would  consider sublicensing to Conductus, as  they issue, any other foreign and
U.S. patent applications licensed  to DuPont by the  University of Houston.  The
Company  anticipates that it  will be required  to obtain a  license to use YBCO
from one or  more of  these parties  in order to  continue to  develop and  sell
products based on YBCO.
 
    There  can be no assurance that the Company would able to obtain licenses to
patents covering  YBCO  compositions,  when  issued, or  to  any  other  patents
applicable  to the Company's business on  commercially reasonable terms. In such
an event,  the Company  could be  required to  expend significant  resources  to
develop  non-infringing  technology alternatives  or to  obtain licenses  to the
technology that  the  Company infringes  or  would  infringe. There  can  be  no
assurance  that the  Company would be  able to successfully  design around these
third party patents  or to obtain  licenses to technology  that it may  require.
Furthermore, there can be no assurance that the Company will not be obligated to
defend  itself at substantial cost against  allegations of infringement of third
party patents. An adverse outcome  in such a suit  could subject the Company  to
significant  liabilities to third parties, or require the Company to cease using
such technology. In  addition, aside from  the merits  of a claim,  the cost  of
defending  any  such suit  would  constitute a  major  financial burden  for the
Company that  would  materially  adversely affect  on  its  business,  operating
results and financial condition. See "Risk Factors -- Uncertainty of Patents and
Proprietary Rights; Risk of Litigation."
 
    Conductus  has  granted to  various entities  non-exclusive, royalty-bearing
licenses to  certain  of its  proprietary  technology for  the  manufacture  and
distribution  of various equipment, including rotating target holders, substrate
heaters and  mutual  inductance  probes  to be  used  in  cryogenic  measurement
systems.  Through its strategic relationships,  Conductus has received rights to
certain intellectual property developed by its partners, as well as  commitments
from  those  partners  to  offer  licenses  to  certain  background  technology.
Conductus cannot, however, be certain that  such licenses will be on terms  that
allow  Conductus to compete effectively in the marketplace. See "Risk Factors --
Uncertainty of Patents and Proprietary Rights; Risk of Litigation."
 
    Conductus owns  the United  States  registered trademarks  "CONDUCTUS,"  the
Conductus  logo, "Mr. SQUID" and  "iMAG" and claims the  rights to the trademark
"xMAG."

MANUFACTURING
 
    Conductus  has  performed  pioneering  work  in  materials,  processes   and
structures  based  on thin-film  superconducting  technology, and  has developed
processes  it  believes  are  capable  of  routinely  producing  a  variety   of
high-quality  films  for  several applications,  including  multilayer thin-film
materials suitable  for  more  complex devices  and  components.  Conductus  has
established  a  pilot  production  facility at  its  headquarters  in Sunnyvale,
California  to  fabricate,  test  and  assemble  HTS  and  LTS  thin  films  and
components.  The Company  fabricates two-,  three- and  four-inch wafers  in two
cleanroom areas that consist,  in the aggregate,  of approximately 2,600  square
feet and that have ratings of subclass 1,000 and 10,000 (meaning there are fewer
than  1,000 or 10,000 particles larger than  0.5 microns per cubic foot of air).
See "Business --  Properties." Conductus  combines what  it believes  to be  the
world's most advanced YBCO thin-film technology with expertise in electronic and
device  component design,  analog and digital  electronic engineering, cryogenic
packaging, mechanical engineering and system integration.
 
    The primary  materials and  equipment used  in Conductus'  products  include
substrates,  YBCO and processing equipment.  The Company procures its substrates
from several suppliers. The Company procures  its YBCO source material from  two
suppliers  and  believes that  YBCO  can be  obtained  from at  least  two other
vendors. For certain  processes, Conductus utilizes  elemental metals  (yttrium,
barium and copper) to produce YBCO. These substances are available from numerous
vendors.  The  Company's processing  equipment  is assembled  from off-the-shelf
components which can be obtained from multiple sources.
 
    Conductus believes  that most  of its  products for  the communications  and
healthcare   markets  will  be  in  the  form  of  subsystems  that  incorporate
superconducting and cryoelectronic components  with cryogenic refrigerators  and
conventional  electronic assemblies.  Apart from  the superconducting components
which are manufactured  by Conductus,  the Company anticipates  that most  other
components  of  its  subsystems  will be  purchased  as  standard  products from
commercial vendors or  specially ordered from  various suppliers. These  include
cryogenic  refrigerators, printed  circuit boards,  product cases  and housings,
vacuum  vessels  and   other  components.  Certain   components  of   Conductus'
subsystems,  including cryocoolers, are currently  obtained from a single source
or a limited number of suppliers. Although the Company does not believe that  it
is  ultimately dependent upon any supplier of  these components as a sole source
or limited source for any critical  components, the inability of the Company  to
develop  alternative  sources,  if  required, an  inability  to  meet  demand, a
prolonged interruption in supply  or a significant increase  in price of one  or
more  components would have a material adverse effect on the Company's business,
operating results and financial condition. See  "Risk Factors -- High Degree  of
Dependence  Upon  Other  Complementary  Technologies,  Limited  or  Sole  Source
Suppliers."
 
    Conductus is focusing on the development of its production processes and  is
manufacturing limited quantities of superconducting components and prototypes at
its Sunnyvale, California facility. Apart from the production of superconducting
components,  the Company's manufacturing activities generally will be limited to
cleaning, final  assembly,  vacuum bakeout  and  test procedures.  Conductus  is
producing  these products in limited commercial  quantities and is continuing to
expand its capabilities. See "Risk  Factors -- Limited Commercial  Manufacturing
Capability."  At its Instrument  and Systems Division  in San Diego, California,
Conductus designs and manufactures large-scale superconductive magnetic  sensing
systems  using these superconductive components.  This facility also designs and
manufactures electronic  instruments  and  circuitry used  in  conjunction  with
superconductive components.
 
COMPETITION
 
    Although  the market for superconductive  electronics currently is small and
in the early stages of development,  Conductus believes this market will  become
intensely   competitive  if  products  with  significant  market  potential  are
successfully developed.
 
    A number of large American, Japanese  and European companies are engaged  in
research  and development programs  that the Company believes  could lead to the
development and/or  commercialization  of superconductive  electronic  products.
These    include,   among    others:   DuPont,    IBM,   TRW,    and   Northrop-
 
                                       35
<PAGE>
Grumman Corporation in the U.S.; and  Fujitsu Ltd., Hitachi Ltd., NEC Corp.  and
Sumitomo  Electric Industries, Ltd.  in Japan. The Company  also believes that a
number of smaller companies  are engaged in various  aspects of the  development
and  commercialization of  superconductive electronics  products. These include,
among others, Biomagnetic Technology, Inc. and Quantum Design, Inc. in  magnetic
sensing products; Hypres, Inc. in digital circuits; and Illinois Superconducting
Corp.,  Superconducting Core Technologies,  Inc. and Superconductor Technologies
Inc.   in   wireless   communications.   Furthermore,   academic   institutions,
governmental  agencies and other  public and private  research organizations are
engaged in development programs which  may lead to competitive arrangements  for
commercializing  superconductive  electronics  products.  In  addition,  if  the
superconductor industry does develop further, new competitors with significantly
greater resources are likely to enter  the field. Conductus' ability to  compete
successfully  will require it  to develop and  maintain technologically advanced
products, attract and retain highly qualified personnel, obtain patent or  other
protection  for  its  technology and  products  and manufacture  and  market its
products, either  alone or  with third  parties. See  "Risk Factors  --  Intense
Competition."
 
    The   Company's  existing  collaborative  arrangements  permit,  and  future
arrangements also may permit, the Company and each partner to use the technology
developed under these  arrangements. Accordingly, the  Company may compete  with
its  partners  for  commercial  sales  of  any  products  developed  under these
arrangements.
 
    The Company's  potential products,  if successfully  developed, may  compete
directly   with  other  existing  and   subsequently  developed  products  using
competitive, conventional  technologies.  There can  be  no assurance  that  the
Company's  products will have sufficient performance advantages over these other
products to attract significant commercial  interest. These and related  factors
may   limit   market  acceptance   of  products   incorporating  superconductive
technology. See "Risk Factors -- Competing Technologies."
 
    Conductus believes that the principal competitive factors in the market  for
superconductive  electronics  will  be  the following:  the  ability  to develop
commercial applications  of  superconductive  technology;  product  performance,
including,  where appropriate,  speed, sensitivity, size  and power dissipation;
price; product  quality  and reputation.  Conductus  believes that  it  compares
favorably with respect to these factors.
 
SALES AND MARKETING
 
    Although   Conductus  has   limited  experience  in   sales,  marketing  and
distribution, it has been expanding its expertise and activities in these  areas
in  order to successfully commercialize  its potential products. Conductus sells
its products through  a combination  of OEM  relationships, direct  sales and  a
network  of  independent  manufacturer's representatives  and  distributors. The
Company's sales and marketing strategy is to use manufacturers'  representatives
and   distributors  for  sales  of  its  magnetic  sensor-based  and  laboratory
instrument products and to rely primarily on OEMs for its subsystem products for
communications, healthcare and  instrumentation. The Company  has established  a
domestic and international network of independent manufacturer's representatives
who  have  primary responsibility  for selling  magnetic sensing  and laboratory
instrumentation products. As of  March 31, 1996,  17 domestic and  international
firms  were manufacturer's representatives and  distributors, covering 42 states
and certain foreign countries including a majority of Europe, Japan,  Australia,
Taiwan and India. See "Risk Factors -- Need to Develop Infrastructure to Support
Commercialization."
 
    The  Company currently employs a sales and marketing staff of nine full-time
equivalents. These employees are actively engaged in direct marketing to OEM and
potential OEM customers, as well as in sales and marketing support. The  Company
actively  markets its products through advertisements  in trade journals as well
as through demonstration of its technology and products at industry trade shows,
including trade  shows  related  to telecommunications,  NMR  spectroscopy,  MRI
imaging  and  magnetic  sensing.  The  Company  publishes  widely  in  trade and
technical journals. Additionally, Conductus' employees have frequently presented
Conductus' technology as invited speakers at conferences worldwide.
 
                                       36
<PAGE>
    For the three months ended  March 31, 1996 and  fiscal years 1995, 1994  and
1993,  commercial sales  to one customer  of $241,000,  $1,172,000, $732,000 and
$816,000 were 9%, 11%, 8% and 13% of total revenues, respectively. This customer
acts primarily as a distributor of the Company's products, selling to end-users.
 
ENVIRONMENTAL MATTERS
 
    The  Company  uses   certain  hazardous  materials   in  its  research   and
manufacturing  operations. As a  result, Conductus is  subject to federal, state
and local governmental regulations. Conductus believes that it has complied with
all regulations and has all permits necessary to conduct its business. See "Risk
Factors -- Environmental Regulations."
 
PROPERTIES
 
    The Company's principal facility,  including its pilot production  facility,
is  located  in  two buildings  providing  approximately 40,000  square  feet of
available space in Sunnyvale, California.  In November 1994, the Company  signed
new  leases  on  both buildings  which  will  expire in  August  2000  and 2001,
respectively. The increase in space will facilitate expansion for  manufacturing
and  development efforts. Conductus also leases approximately 10,000 square feet
in San Diego, California under a lease  expiring in 1998 for its Instrument  and
Systems  Division. The Company believes its existing facilities are adequate and
suitable for  its  current  needs,  and additional  space  can  be  obtained  on
commercially reasonable terms as needed to expand the Company's operations.
 
LEGAL PROCEEDINGS
 
    One  Conductus  patent  covering  technology  related  to  certain  magnetic
resonance probe coils is currently subject to an interference proceeding with  a
competitor,  Superconductor Technologies, Inc., before  the Patent and Trademark
Office. Based on  the Company's  current product development  plan, the  Company
does  not believe  that an  adverse resolution  of the  proceeding would  have a
material  adverse  effect  on  its  business  operating  results  or   financial
condition.  The Company  is not a  party to  any material litigation  and is not
aware of any  pending or threatened  litigation against the  Company that  could
have a material adverse effect upon the Company's business, operating results or
financial condition. See "Risk Factors -- Uncertainty of Patents and Proprietary
Rights; Risk of Litigation."
 
EMPLOYEES
 
    As  of March 31, 1996,  the Company had a  total of 105 full-time equivalent
employees of which 46 hold advanced  degrees. Of the total full-time  employees,
65  were engaged in research and  product development, 11 in manufacturing, nine
in sales  and  marketing, three  in  operations  and 17  in  administration  and
finance.  None of the Company's  employees is represented by  a labor union. The
Company has not experienced any work stoppages and considers its relations  with
its employees to be good.

- ------------------------
(1) The  options granted to Dr. Simon and Mr. Tamblyn are immediately subject to
    a right of repurchase in  favor of the Company  that lapses as follows:  20%
    upon  the completion of the  first year of service  measured from January 1,
    1995 and an additional  1.67% upon the completion  of each month of  service
    elapsed  thereafter,  until  the  option  shall  be  fully  vested  upon the
    completion of the fifth year of service
 
                                       40
<PAGE>
    from the vesting date. The options were granted January 24, 1995, and  began
    vesting  on January  1, 1995.  The exercise  price may  be paid  in cash, in
    shares of Common Stock valued at fair  market value on the exercise date  or
    through  a  cashless exercise  procedure involving  a  same-day sale  of the
    purchased shares.  The  Company may  also  finance the  option  exercise  by
    loaning  the optionee  sufficient funds  to pay  the exercise  price for the
    purchased shares and the federal and state income tax liability incurred  by
    the  optionee in connection  with such exercise.  The Compensation Committee
    has the discretionary authority to  reprice outstanding options through  the
    cancellation  of those options and the  grant of replacement options with an
    exercise price equal to the lower fair market value of the option shares  on
    the regrant date.
 
(2) There  is no assurance provided to any executive officer or any other holder
    of the Company's securities  that the actual  stock price appreciation  over
    the  10-year option term will be at the  assumed 5% and 10% levels or at any
    other defined level.

(2) Each  option is immediately  exercisable for all the  option shares, but any
    shares purchased  under the  option will  be subject  to repurchase  by  the
    Company,  at  the original  exercise price  per  share, upon  the optionee's
    cessation of service  prior to vesting  in such shares.  As of December  31,
    1995,  the  Company's  repurchase  right  had  lapsed  with  respect  to the
    following number of option shares: Mr.  Shalvoy -- 69,998; Mr. MacMillan  --
    28,333; Dr. Simon -- 33,806; and Mr. Tamblyn -- 13,666.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    John  F. Shoch,  who became  a member of  the Compensation  Committee of the
Board of Directors in May 1993, is  a general partner of AMC Partners 84,  which
is the general partner of Asset Management Associates 1984, the beneficial owner
of  more  than 5%  of  the Company's  Common Stock.  Dr.  Shoch served  as Chief
Executive Officer of the Company from September 1987 until October 1988.
 
    For information concerning grants of options to certain non-employee members
of the Board  of Directors, including  Dr. Shoch and  Mr. McKenna, see  "Certain
Transactions -- Option Grants."
 
    The  Company has entered  into separate indemnification  agreements with its
directors and  officers.  These  agreements require  the  Company,  among  other
things,  to indemnify them against certain  liabilities that may arise by reason
of their status  or service  as directors  or officers  (other than  liabilities
arising  from actions  not taken  in good  faith or  in a  manner the indemnitee
believed to be opposed  to the best  interest of the  Company) to advance  their
expenses  incurred as a result  of any proceeding against  them as to which they
could be  indemnified  and  to  obtain director's  and  officers'  insurance  if
available on reasonable terms.

EMPLOYMENT CONTRACTS
 
    None  of the  Company's executive officers  (other than  Charles E. Shalvoy)
have employment  agreements  with  the  Company, and  their  employment  may  be
terminated  at any time at the discretion of the Board. The Company entered into
an agreement  with Mr.  Shalvoy,  the Company's  President and  Chief  Executive
Officer,  on May 3, 1994,  which provides for accelerated  vesting of his option
shares as if he remained employed for one additional year in the event that  his
employment  is terminated without cause  following certain mergers, acquisitions
or sales of all or substantially all of the assets of the Company. In  addition,
the  Compensation Committee has the authority  as Plan Administrator of the 1992
Stock Option/ Stock Issuance Plan to provide for the accelerated vesting of  the
shares  of  Common  Stock  subject  to outstanding  options  held  by  the Chief
Executive Officer and  the Company's other  executive officers, whether  granted
under  that plan or any predecessor plan,  in the event their employment were to
be terminated (whether involuntarily or through a forced resignation)  following
(i)  an acquisition  of the Company  by merger or  asset sale or  (ii) a hostile
takeover of the Company effected through a successful tender offer for more than
50% of  the  Company's outstanding  Common  Stock or  through  a change  in  the
majority  of the Board as a result of  one or more contested elections for Board
membership.
 
1992 STOCK OPTION/STOCK ISSUANCE PLAN
 
    The Company's 1992 Stock  Option/Stock Issuance Plan  (the "1992 Plan")  was
adopted  by the  Board of  Directors on  January 11,  1992, and  approved by the
stockholders on April 25, 1992  as the successor to  the 1987 Stock Option  Plan
and 1989 Stock Option Plan ("Predecessor Plans"). The 1992 Plan has been amended
on  numerous occasions, most recently in January  1996 to increase the number of
shares issuable under the  1992 Plan. The January  1996 amendment is subject  to
stockholder  approval at the 1996 annual meeting. A total of 1,880,000 shares of
Common Stock have been authorized for issuance under the 1992 Plan. As of  March
31,  1996,  310,784 shares  had been  issued  under the  1992 Plan,  options for
1,157,026 shares  were  outstanding  (including options  incorporated  from  the
Predecessor  Plans)  and 412,190  shares  remained available  for  future grant.
Shares of Common Stock subject to outstanding options, including options granted
under the Predecessor Plans, which expire or terminate prior to exercise will be
available for future issuance under the 1992 Plan.
 
    The  1995  Plan  is  divided   into  three  separate  components:  (i)   the
Discretionary  Option Grant  Program under which  employees (including officers)
and independent consultants may, at the discretion of the Plan Administrator, be
granted options to  purchase shares  of Common Stock  at an  exercise price  per
share  not less than 85% of fair market  value on the grant date, (ii) the Stock
Issuance Program under which such  individuals may, in the plan  administrator's
discretion,  be issued shares of Common  Stock directly, through the purchase of
such shares at  a price per  share not less  than 85% of  fair market value  per
share at the time of issuance or as a fully-paid bonus for services rendered the
Company;  and (iii) the Automatic Option Grant Program under which option grants
will automatically be made at periodic intervals to eligible non-employee  Board
members to purchase shares of Common Stock at an exercise price equal to 100% of
the fair market value of the option shares on the grant date.
 
    The  Discretionary Option Grant  Program and the  Stock Issuance Program are
administered by  the  Compensation  Committee of  the  Board.  The  Compensation
Committee,  as plan  administrator, has  complete discretion  to determine which
eligible individuals are to receive option  grants or stock issuances, the  time
or  times when such option grants or stock  issuances are to be made, the number
of shares subject  to each such  grant or  issuance, the status  of any  granted
option  as either an incentive  stock or a non-statutory  stock option under the
Federal tax laws, the vesting schedule to  be in effect for the option grant  or
stock  issuance and the maximum  term for which any  granted option is to remain
outstanding. In no  event, however,  may any one  participant in  the 1992  Plan
acquire  more than 240,000 shares of Common Stock under the 1992 Plan, exclusive
of any option grants or share issuances received prior to December 31, 1993.
 
    The exercise price for options  granted under the 1992  Plan may be paid  in
cash  or in outstanding shares of Common Stock. Options may also be exercised on
a cashless basis through the same-day sale of the
 
                                       42
<PAGE>
purchased shares. The Compensation Committee may also permit the optionee to pay
the exercise price  through a  promissory note  payable in  installments over  a
period of years. The amount financed may include any Federal or state income and
employment taxes incurred by reason of the option exercise.
 
    Each  option granted to an officer of the Company subject to the short-swing
profit restrictions of the Federal securities  laws may include a special  stock
appreciation  right which provides that, upon the  acquisition of 50% or more of
the Company's outstanding voting stock pursuant to a hostile tender offer,  such
option,  if outstanding for at least six months, will automatically be cancelled
in exchange for a cash distribution to  the officer based upon the tender  offer
price.
 
    The  Compensation Committee has the authority  to effect, from time to time,
the cancellation of outstanding  options under the 1992  Plan in return for  the
grant  of new options for the same or  different number of option shares with an
exercise price per share based upon the fair market value of the Common Stock on
the new grant date.
 
    In the event the Company is acquired by merger, consolidation or asset sale,
the shares of Common Stock subject to each option outstanding at the time  under
the  1992 Plan will immediately vest in full, except to the extent the Company's
repurchase rights  with  respect to  those  shares are  to  be assigned  to  the
acquiring  entity, and options will accelerate to  the extent not assumed by the
acquiring entity. The Compensation Committee also has discretion to provide  for
the  acceleration  of  one  or  more outstanding  options  under  the  1992 Plan
(including options incorporated from  the 1992 Plan) and  the vesting of  shares
subject  to outstanding  options upon the  occurrence of  certain hostile tender
offers.  Such  accelerated  vesting  may  be  conditioned  upon  the  subsequent
termination of the affected optionee's service.
 
    Under the automatic grant program, each individual serving as a non-employee
director on January 23, 1995, and each individual who first joins the Board as a
non-employee  director  on or  after that  date,  will receive  at that  time an
automatic option grant for 15,000 shares of Common Stock. Each option will  have
an  exercise price  equal to the  fair market value  of the Common  Stock on the
automatic grant  date  and a  maximum  term of  ten  years, subject  to  earlier
termination following the optionee's cessation of Board service. The option will
be  immediately exercisable for all of the shares but the shares will be subject
to repurchase  at  original cost.  The  repurchase  right shall  lapse  and  the
optionee vest in a series of annual and monthly installments over a five-period,
beginning  one year  from the  grant date. However,  vesting of  the shares will
automatically accelerate  upon (i)  an  acquisition of  the Company  by  merger,
consolidation, or asset sale, or (ii) a hostile takeover of the Company effected
by  tender offer  for more  than 50%  of the  outstanding voting  stock or proxy
contest for Board membership.
 
    In the event that  more than 50% of  the Company's outstanding voting  stock
were  to be acquired pursuant  to a hostile tender  offer, each automatic option
grant which has been outstanding for at  least six months may be surrendered  to
the  Company in return for  a cash distribution from  the Company based upon the
tender offer  price  per share  of  Common Stock  at  the time  subject  to  the
surrendered option.
 
    The  Board may amend or modify the 1992 Plan at any time. The 1992 Plan will
terminate on January 10, 2002 unless sooner terminated by the Board.
 
EMPLOYEE STOCK PURCHASE PLAN
 
    The Company adopted on August 1,  1994 an Employee Stock Purchase Plan  (the
"Purchase  Plan"). A total of 200,000 shares  of Common Stock have been reserved
for issuance under the  Purchase Plan. The Purchase  Plan, which is intended  to
qualify  under Section  423 of the  Internal Revenue Code,  has been implemented
through a series  of offering periods,  each with a  maximum duration of  twelve
months,  commencing on  August 1,  1994, with  purchases generally  occurring at
six-month intervals.  The  Purchase Plan  is  administered by  the  Compensation
Committee  of  the Board.  Employees  are eligible  to  participate if  they are
employed by the Company for at least 20 hours per week and have been employed by
the Company  for  at least  ninety  days.  The Purchase  Plan  permits  eligible
employees  to purchase  Common Stock through  payroll deductions,  which may not
exceed 10%  of  an employee's  compensation,  nor  more than  2,500  shares  per
participant  on  any  purchase date.  The  price  of stock  purchased  under the
Purchase Plan will be 85% of
 
                                       43
<PAGE>
the lower of the fair market value of  the Common Stock at the beginning of  the
offering   or  on  the  semi-annual  purchase  date.  Employees  may  end  their
participation in  the offering  at  any time  during  the purchase  period,  and
participation  ends automatically on termination of employment with the Company.
Each outstanding purchase right will be exercised immediately prior to a  merger
or  consolidation unless  assumed by  the acquiring  corporation. The  Board may
amend or terminate the Purchase Plan immediately after the close of any purchase
period. However, the  Board may  not, without  stockholder approval,  materially
increase  the  number  of  shares  of Common  Stock  available  for  issuance or
materially modify the eligibility requirements for participation or the benefits
available to participants.
 
401(K) PROFIT SHARING PLAN
 
    Effective January 1, 1988, the  Company adopted a retirement profit  sharing
plan (the "401(k) Plan") that covers all employees of the Company in the U.S. An
employee may elect to defer, in the form of contributions to the 401(k) Plan, up
to  15% of the total compensation that  would otherwise be paid to the employee,
currently not to exceed  $9,500 per calendar  year (adjusted for  cost-of-living
increases).  Employee contributions are invested in selected equity mutual funds
or a money market fund at the  direction of the employee. The contributions  are
fully vested and nonforfeitable at all times.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The  Company's Restated Certificate of Incorporation limits the liability of
its directors for monetary damages arising from a breach of their fiduciary duty
as directors, except to  the extent otherwise required  by the Delaware  General
Corporation  Law. Such limitation of liability  does not affect the availability
of equitable remedies  such as  injunctive relief or  rescission. The  Company's
Bylaws  provide that the  Company shall indemnify its  directors and officers to
the fullest  extent permitted  by Delaware  law, including  in circumstances  in
which indemnification is otherwise discretionary under Delaware law. The Company
has  also entered into  indemnification agreements with  its officers, directors
and certain employees containing provisions that may require the Company,  among
other  things,  to  indemnify  such officers,  directors  and  employees against
certain liabilities  that may  arise by  reason of  their status  or service  as
directors,  officers or employees  (other than liabilities  arising from willful
misconduct of a culpable nature), to advance their expenses incurred as a result
of any proceeding against  them as to  which they could  be indemnified, and  to
obtain  directors' and officers' insurance if available on reasonable terms. The
Company believes that these provisions  and agreements are necessary to  attract
and retain qualified directors, executive officers and certain employees.
 
    At  present,  there is  no pending  litigation  or proceeding  involving any
director, officer, employee or agent  of the Company where indemnification  will
be  required or permitted. The Company is not aware of any threatened litigation
or proceeding that might result in a claim for such indemnification.
 
                              CERTAIN TRANSACTIONS
 
RELATIONSHIP WITH H-P
 
    In May 1993, the  Company and H-P modified  a previous Coordinated  Research
Program  Agreement (the "Prior H-P Agreement")  by entering into a new five-year
agreement (the "Current H-P Agreement"). Under the Prior H-P Agreement, H-P  and
Conductus  were involved  in several  joint development  projects, including the
development of  a stable,  low  phase-noise oscillator  for microwave  test  and
instrumentation  applications using  resonators developed by  Conductus, and the
development of  a  variety  of  digital  LTS  circuits  for  high-speed  digital
electronic   applications.  All  rights  to  technology  arising  out  of  joint
development projects are owned jointly by  H-P and Conductus. As a result,  both
Conductus  and H-P will be entitled to commercialize products incorporating such
technology.
 
    Any royalties received by either  H-P or Conductus for technology  developed
under  the Prior H-P Agreement will be  divided equally between the two parties,
except that Conductus generally may not  license third parties to make  circuits
based  on  circuit designs  made  solely by  H-P employees  as  part of  a joint
 
                                       44
<PAGE>
development project or  sell such  circuits to third  parties for  incorporation
into  products for resale. H-P is  a party to certain cross-license arrangements
and may  in the  future enter  into similar  cross-licenses. Consequently,  such
third  parties  may  have  non-exclusive rights  in  technology  developed under
research projects  under  the Prior  H-P  Agreement.  H-P also  has  the  right,
beginning two years after information developed under the Prior H-P Agreement or
disclosed  to the  other party is  designated as confidential,  to disclose such
information to third parties or  to the public (including information  disclosed
to   H-P  by  Conductus).  Conductus  has  comparable  license  and  information
disclosure rights.
 
    The Current H-P Agreement requires Conductus and H-P to exchange reviews and
assessments of Conductus' technical and applications developments,  particularly
with  respect to their potential application to H-P's product lines. H-P has the
right to appoint an H-P employee (the "H-P Member") as a member of the Company's
Scientific Advisory Board. H-P will jointly own with Conductus any invention  by
the  H-P Member  acting pursuant  to the  H-P Agreement  or using  the Company's
confidential information.
 
    Mr. Anderson,  Vice  President and  General  Manager of  the  Microwave  and
Communication  Group at  H-P, was  nominated for election  as a  director of the
Company by  H-P pursuant  to the  Series B  Preferred Stock  Purchase  Agreement
between  the  Company  and  H-P.  See  "Management  --  Directors  and Executive
Officers."
 
    Between January 1990  and June  1993, Conductus  and H-P  entered into  four
equipment lease lines, pursuant to which Conductus leased equipment and incurred
monthly payments in the aggregate of approximately $166,500, including principal
and interest. Three of the four lease lines expired in May 1993.
 
SELECTED PREVIOUS FINANCINGS
 
    In  October  1992  and January  1993,  the  Company raised  an  aggregate of
$2,000,000  to  finance  its  operations  through  the  issuance  of  $1,980,000
principal  amount of  convertible promissory  notes bearing  interest at  9% per
annum (the  "Promissory Notes"),  and warrants  to purchase  Series B  Preferred
Stock  that converted into warrants to purchase an aggregate of 33,460 shares of
Common Stock at the closing of the Company's initial public offering (the "IPO")
in August 1993. The warrants had an effective exercise price of $8.96 per  share
of  Common Stock. The Promissory Notes and warrants were issued to affiliates of
the following persons,  each of  which beneficially owned  more than  5% of  the
Company's Common Stock as of March 31, 1996:

    The  expiration date of these  warrants was extended by  two years in August
1993 in exchange for the agreement of the warrant holders to enter into  lock-up
agreements  in  connection with  the IPO.  The warrants  expired in  August 1995
without being exercised.
 
    As a result of their respective positions as general partners or as  general

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The  Company's Restated Certificate of Incorporation limits the liability of
its directors for monetary damages arising from a breach of their fiduciary duty
as directors, except to  the extent otherwise required  by the Delaware  General
Corporation  Law. Such limitation of liability  does not affect the availability
of equitable remedies  such as  injunctive relief or  rescission. The  Company's
Bylaws  provide that the  Company shall indemnify its  directors and officers to
the fullest  extent permitted  by Delaware  law, including  in circumstances  in
which indemnification is otherwise discretionary under Delaware law. The Company
has  also entered into  indemnification agreements with  its officers, directors
and certain employees containing provisions that may require the Company,  among
other   things,  to  indemnify  such  officers  and  directors  against  certain
liabilities that may arise by reason of their status or service as directors  or
officers  (other than liabilities arising from  willful misconduct of a culpable
nature), to  advance their  expenses  incurred as  a  result of  any  proceeding
against them as to which they could be indemnified, and to obtain directors' and
officers'  insurance  if  available  on  reasonable  terms.  See  "Management --
Limitation of Liability and Indemnification Matters."
 
OPTION GRANTS
 
    On January  23, 1995,  the Company  granted each  of Dr.  Shoch and  Messrs.
McKenna  and  Sun an  option to  purchase 15,000  shares of  Common Stock  at an
exercise price of $4.93 per share pursuant to the Automatic Option Grant Program
under the 1992 Plan.  On January 25,  1996, the Company  granted Mr. Saldich  an
option  to purchase 15,000 shares of Common  Stock at an exercise price of $6.50
per  share  pursuant  to  the  same  program.  See  "Management  --  1992  Stock
Option/Stock Issuance Plan."
 
    On  May 3,  1994, the  Company granted  Mr. Shalvoy  options to  purchase an
aggregate of 250,000 shares of  Common Stock at an  exercise price of $5.50  per
share, including 240,000 shares granted pursuant to the 1992 Plan, in connection
with  Mr. Shalvoy joining the Company  as President and Chief Executive Officer.

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of 11,000,000 shares of
Common  Stock,  $0.0001  par value,  and  1,000,000 shares  of  Preferred Stock,
$0.0001 par value.
 
COMMON STOCK
 
    As  of  March  31,  1996,  there  were  5,732,989  shares  of  Common  Stock
outstanding  that were held of record. There  will be 6,732,989 shares of Common
Stock outstanding  (assuming no  exercise  of the  Underwriters'  over-allotment
option  and assuming no  exercise after March 31,  1996, of outstanding options)
after giving effect  to the sale  of the shares  of Common Stock  to the  public
offered hereby.
 
    The  holders  of Common  Stock are  entitled to  one vote  per share  on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding Preferred Stock,  the holders of Common Stock  are
entitled to receive ratably such dividends, if any, as may be declared from time
to  time by the Board of Directors  out of funds legally available therefor. See
"Price Range  of  Common  Stock  and  Dividend Policy."  In  the  event  of  the
liquidation,  dissolution or  winding up of  the Company, the  holders of Common
Stock are entitled  to share ratably  in all assets  remaining after payment  of
liabilities,  subject to prior  distribution rights of  Preferred Stock, if any,
then outstanding. The  Common Stock has  no preemptive or  conversion rights  or
other  subscription rights. There  are no redemption  or sinking fund provisions
applicable to the Common Stock. All outstanding shares of Common Stock are fully
paid and  nonassessable,  and the  shares  of Common  Stock  to be  issued  upon
completion of this offering will be fully paid and nonassessable.
 
PREFERRED STOCK
 
    The Board of Directors has the authority to issue the Preferred Stock in one
or  more series and to fix  the rights, preferences, privileges and restrictions
thereof, including dividend  rights, dividend rates,  conversion rights,  voting
rights,  terms of redemption, redemption prices, liquidation preferences and the
number of shares  constituting any  series or  the designation  of such  series,
without  further vote or  action by the stockholders.  The issuance of Preferred
Stock may  have the  effect of  delaying, deferring  or preventing  a change  in
control  of  the Company  without  further action  by  the stockholders  and may
adversely affect the voting and other rights of the holders of Common Stock. The
issuance of  Preferred Stock  with voting  and conversion  rights may  adversely
affect  the voting power of  the holders of Common  Stock, including the loss of
voting control to others. At present, the  Company has no plans to issue any  of
the Preferred Stock.
 
ANTITAKEOVER EFFECTS OF PROVISIONS OF THE RESTATED CERTIFICATE OF INCORPORATION
AND BYLAWS AND OF DELAWARE LAW
 
  RESTATED CERTIFICATE OF INCORPORATION
 
    Under  the  Company's Restated  Certificate of  Incorporation, the  Board of
Directors has the power to authorize the  issuance of up to 1,000,000 shares  of
Preferred  Stock and to determine the price, rights, preferences, privileges and
restrictions, including voting rights, of  those shares without further vote  or
action  by the  stockholders. The issuance  of Preferred  Stock, while providing
desirable  flexibility  in  connection  with  possible  acquisitions  and  other
corporate  purposes, may have the effect  of delaying, deferring or preventing a
change in control of the Company, may discourage bids for the Common Stock at  a
premium  over the market price of the  Common Stock and may adversely affect the
market price of and  the voting and  other rights of the  holders of the  Common
Stock.  In addition,  the Restated  Certificate of  Incorporation provides that,
effective upon the  closing of this  offering, all stockholder  actions must  be
effected  at  a duly  called  meeting and  not by  a  consent in  writing. These
provisions  of  the  Restated  Certificate  of  Incorporation  could  discourage
potential  acquisition proposals and could delay  or prevent a change in control
of the  Company. These  provisions are  intended to  enhance the  likelihood  of
continuity and stability in the composition of the Board of Directors and in the
policies  formulated by the  Board of Directors and  to discourage certain types
 
                                       49
<PAGE>
of transactions that may  involve an actual or  threatened change of control  of
the  Company. These provisions  are designed to reduce  the vulnerability of the
Company to  an  unsolicited  acquisition proposal.  These  provisions  are  also
intended  to  discourage  certain tactics  that  may  be used  in  proxy fights.
However, such  provisions could  have  the effect  of discouraging  others  from
making  tender offers for the Company's shares  and, as a consequence, they also
may inhibit fluctuations in the market price of the Company's shares which could
result from actual or rumored takeover  attempts. Such provisions also may  have
the  effect of preventing  changes in the  management of the  Company. See "Risk
Factors --  Effect  of  Certain  Charter  Provisions;  Antitakeover  Effects  of
Restated Certificate of Incorporation and Bylaw Provisions and of Delaware Law."
 
  DELAWARE TAKEOVER STATUTE
 
    The  Company is subject  to Section 203 of  the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a  Delaware
corporation  from  engaging  in  any business  combination  with  any interested
stockholder for a period of three years following the date that such stockholder
became an interested stockholder, unless: (i)  prior to such date, the board  of
directors  of the  corporation approved either  the business  combination or the
transaction that resulted in the stockholder becoming an interested stockholder;
(ii) upon  consummation of  the  transaction that  resulted in  the  stockholder
becoming  an interested stockholder,  the interested stockholder  owned at least
85% of  the  voting  stock  of  the corporation  outstanding  at  the  time  the
transaction  commenced,  excluding for  purposes  of determining  the  number of
shares outstanding those shares owned (x) by persons who are directors and  also
officers  and (y) by employee stock plans  in which employee participants do not
have the right to  determine confidentially whether shares  held subject to  the
plan  will be tendered in a tender or  exchange offer; or (iii) on or subsequent
to such date, the business combination is approved by the board of directors and
authorized at an annual or special  meeting of stockholders, and not by  written
consent,  by the affirmative vote of at  least 66 2/3% of the outstanding voting
stock that is not owned by the interested stockholder.
 
    Section 203  defines business  combination  to include:  (i) any  merger  or
consolidation involving the corporation and the interested stockholder; (ii) any
sale,  transfer, pledge or other disposition of 10% or more of the assets of the
corporation involving  the  interested  stockholder; (iii)  subject  to  certain
exceptions,  any transaction  that results  in the  issuance or  transfer by the
corporation of any stock of the corporation to the interested stockholder;  (iv)
any  transaction involving the corporation that has the effect of increasing the
proportionate share  of the  stock of  any class  or series  of the  corporation
beneficially  owned by  the interested  stockholder; or  (v) the  receipt by the
interested stockholder  of  the  benefit of  any  loans,  advances,  guarantees,
pledges  or other financial benefits provided  by or through the corporation. In
general, Section 203 defines an interested  stockholder as any entity or  person
beneficially  owning  15%  or  more  of  the  outstanding  voting  stock  of the
corporation  and  any  entity  or  person  affiliated  with  or  controlling  or
controlled by such entity or person.

    The  Underwriters will purchase  all shares of  Common Stock offered hereby,
other than  over-allotment shares,  if any  of such  shares are  purchased.  The
Underwriting Agreement provides that the obligations of the several Underwriters
are subject to conditions precedent specified therein. In the event of a default
by  an  Underwriter,  the  commitment  set  forth  above  of  the non-defaulting
Underwriter may be increased or the Underwriting Agreement may be terminated.
 
    The Company has been  advised by the  Representatives that the  Underwriters
propose  to offer the shares of Common Stock to the public at the offering price
set forth on the cover  page of this Prospectus and  to certain dealers at  such
price  less a  concession not  in excess  of $      per share.  Such dealers may
reallow, a concession not in excess of $    per share to certain other  dealers.
After the public offering, the public offering price, concession and reallowance
to dealers may be changed by the Underwriters.
 
    The  Company has granted  to the Underwriters an  option, exercisable by the
Underwriters not later than 30 days after the effective date of this Prospectus,
to purchase  up to  150,000 additional  shares  of Common  Stock at  the  public
offering  price, less the underwriting  discount set forth on  the cover page of
this Prospectus. The Underwriters may exercise such option, in whole or in part,
only to cover over-allotments made in  connection with the sale of Common  Stock
offered  hereby. To the extent that  the Underwriters exercise such option, each
Underwriter will become  obligated, subject to  certain conditions, to  purchase
approximately  the same percentage  thereof that the number  of shares of Common
Stock to be purchased by it shown in  the above table bears to the total  shown,
and  the Company will be obligated, pursuant  to the option, to sell such shares
to the Underwriters.
 
    In connection with  this offering,  certain underwriters  and selling  group
members  may engage in passive market making transactions in the Common Stock on
the Nasdaq National  Market immediately prior  to the commencement  of sales  in
this  offering, in accordance with Rule 10b-6A under the Securities Exchange Act
of 1934.  Passive  market making  consists  of  displaying bids  on  the  Nasdaq
National  Market  limited by  the bid  prices of  independent market  makers and
purchases limited by  such prices and  effected in response  to order flow.  Net
purchases  by a  passive market  maker on  each day  are limited  to a specified
percentage of the  passive market maker's  average daily trading  volume in  the
Common  Stock during a specified period and must be discontinued when such limit
is reached. Passive market making may  stabilize the market price of the  Common
Stock at a level above that which might otherwise prevail and, if commenced, may
be discontinued at any time.
 
    The  Company  has  agreed  to  indemnify  the  Underwriters  against certain
liabilities, including liabilities under the Securities Act of 1933, as amended,
and to contribute to certain payments  that the Underwriters may be required  to
make.
 
    The  Company has agreed that during the 90-day period commencing on the date
hereof, the  Company  will  not,  without  the  prior  written  consent  of  the

during such 90-day period)  or, after the 90-day  period commencing on the  date
hereof,  effect  any sales  of Common  Stock,  options, warrants  or convertible
securities issued in connection with an acquisition. The Company's directors and
certain officers have  agreed that during  the 90-day period  commencing on  the
date   hereof  they  will  not,  without   the  prior  written  consent  of  the
Underwriters, sell, grant  any option  for the  sale of,  transfer or  otherwise
dispose  (or announce any offer, sale, contract to sell, grant of any option for
sale, transfer or other  disposition) of any shares  of Common Stock other  than

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
Conductus, Inc.:
 
    We  have audited  the accompanying balance  sheets of Conductus,  Inc. as of
December  31,  1995  and  1994,  and  the  related  statements  of   operations,
stockholders'  equity and cash flows  for each of the  three years in the period
ended December 31, 1995.  These financial statements  are the responsibility  of
the  Company's management. Our responsibility is  to express an opinion on these
financial statements based on our audits.
 
    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial  statements referred to above present  fairly,
in  all  material respects,  the  financial position  of  Conductus, Inc.  as of
December 31, 1995 and 1994, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1995, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
           (INFORMATION AS OF MARCH 31, 1996 AND FOR THE THREE MONTHS
           ENDED MARCH 31, 1996 AND 1995 AND THEREAFTER IS UNAUDITED)
 
1.  FORMATION AND BUSINESS OF THE COMPANY:
    The  Company was formed  to develop, manufacture  and market superconductive
electronic devices, circuits  and systems for  sensor, communications, test  and
instrumentation,  and digital electronics applications. Effective June 28, 1994,
the Company  dissolved its  subsidiary, Tristan  Technologies, Inc.  ("Tristan")
acquired in May 1993 and the former Tristan operations have become the Company's
Instrument  and Systems Division.  At that date the  Company discontinued use of
"Consolidated" in the financial statements.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
    FISCAL YEAR:
 
    The Company uses a 52-53 week fiscal  year ending on the last Friday of  the
month.  For convenience  of presentation, the  accompanying financial statements
have been shown as ending on December 31 of each applicable period.
 
    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  reported  amounts of  assets and  liabilities  and
disclosure  of contingent  assets and liabilities  at the date  of the financial
statements and  the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.
 
    CERTAIN RISKS AND CONCENTRATIONS:
 
    The  Company's superconducting  products are concentrated  in the electronic
component industry which  is highly competitive  and rapidly changing.  Revenues
for  the Company's products are concentrated with a relatively limited number of
customers and  supplies for  certain  components are  concentrated among  a  few
providers.   The  development  of  new   technologies  or  commercialization  of
superconductive products  by  any  competitor  could  affect  operating  results
adversely.
 
    CASH, CASH EQUIVALENTS AND INVESTMENTS:
 
    The  Company  considers  all  highly liquid  investments  purchased  with an
original maturity of three months or  less to be cash equivalents.  Investments,
which  consist  primarily of  U.S. government  obligations, corporate  bonds and
commercial paper, are stated at fair market value. Management believes that  the
financial institutions in which it maintains such deposits are financially sound
and,  accordingly, minimal  credit risk exists  with respect  to these deposits.
Additionally, cash and cash equivalents are held by two major banks.
 
    Other financial  instruments,  principally accounts  receivable  and  leases
payable,  are considered to approximate fair  value based upon comparable market
information available at respective balance sheet dates.
 
    As of April 1, 1994, the  Company adopted Statement of Financial  Accounting
Standards  No. 115 ("SFAS 115"), "Accounting for Certain Investments in Debt and
Equity Securities" which  requires a change  in the method  used to account  for
certain  investments. All investments at April 1, 1994 were deemed by management
to be available-for-sale and  therefore are reported at  fair market value  with
net  unrealized losses reported as a separate component of stockholders' equity.
Available-for-sale marketable securities with maturities less than one year from
the balance sheet date  are classified as short-term  and those with  maturities
greater  than one year from the balance  sheet date are classified as long term.
Adoption of SFAS 115 did not have  a material effect on the Company's  financial
statements.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
           (INFORMATION AS OF MARCH 31, 1996 AND FOR THE THREE MONTHS
           ENDED MARCH 31, 1996 AND 1995 AND THEREAFTER IS UNAUDITED)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    INVENTORIES:
 
    Inventories  are  stated at  the lower  of cost  (determined on  a first-in,
first-out basis) or market. Appropriate consideration is given to  obsolescence,
excessive  levels, deterioration and other  factors in evaluating net realizable
value.
 
    PROPERTY AND EQUIPMENT:
 
    Property and equipment are recorded at cost, net of accumulated depreciation
and amortization.
 
    Depreciation of property and equipment are computed using the  straight-line
method  over  estimated  useful lives  of  four  to six  years.  Amortization of
leasehold improvements  is  computed using  the  straight-line method  over  the
shorter of the useful life of the assets and the related lease term.
 
    REVENUE RECOGNITION:
 
    Product revenues are recognized at the time of shipment.
 
    RESEARCH AND DEVELOPMENT CONTRACTS:
 
    The  Company has entered into contracts  to perform research and development
for the U.S. government. Revenues from these contracts are recognized  utilizing
the  percentage-of-completion  method  measured  by  the  relationship  of costs
incurred  to  total  contract  costs.  Costs  include  direct  engineering   and
development costs and applicable overhead.
 
    RESEARCH AND DEVELOPMENT:
 
    Internally  funded  research  and development  expenditures  are  charged to
operations as incurred.
 
    INCOME TAXES:
 
    The Company utilizes the liability method of accounting for income taxes, as
set forth  in Statement  of  Financial Accounting  Standards ("SFAS  No.  109"),
"Accounting  for Income Taxes."  Under the liability  method, deferred taxes are
determined based on the difference between the financial statement and tax bases
of assets and  liabilities using enacted  tax rates  in effect in  the years  in
which the differences are expected to reverse.
 
    UNAUDITED INTERIM FINANCIAL STATEMENTS:
 
    The accompanying unaudited interim financial statements for the three months
ended  March 31, 1996 and  1995 have been prepared  in accordance with generally
accepted  accounting  principles  for  interim  financial  information  and  the
instructions  to Article 10 of Regulation  S-X. Accordingly, they do not include
all of  the information  and  notes required  by generally  accepted  accounting
principles for complete financial statements. In the opinion of the Company, all
adjustments  (consisting of only normal recurring accruals) considered necessary
to present fairly the financial position as of March 31, 1996 and the statements
of operations, stockholders' equity and cash  flows for the three month  periods
ended March 31, 1996 and 1995 have been included.
 
    RECLASSIFICATIONS:
 
    Certain  amounts in the December 31, 1994 and 1993 financial statements have
been reclassified  to conform  to the  presentation at  December 31,  1995.  The
reclassifications  had no impact on previously reported net losses, total assets
or net cashflows.
 
    COMPUTATION OF NET LOSS PER COMMON SHARE:
 
    Net loss  per common  share is  based upon  the weighted  average number  of
common  shares outstanding. Common  equivalent shares have  not been included in
the per share calculations as the effect would not be dilutive.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    RECENT PRONOUNCEMENTS:
 
    During March 1995, the Financial Accounting Standards Board issued Statement
No. 121 ("SFAS 121"),  "Accounting for the Impairment  of Long-Lived Assets  and
for Long-Lived Assets to Be Disposed Of." SFAS 121 will become effective for the
Company's   year  ending  December  31,  1996.   The  Company  has  studied  the
implications of SFAS 121 and, based  on its initial evaluation, does not  expect
it  to have a material impact on the Company's financial condition or results of
operations.
 
    During  October  1995,  the  Financial  Accounting  Standards  Board  issued
Statement  No. 123 ("SFAS 123"), "Accounting for Stock-Based Compensation" which
established a fair value based method of accounting for stock-based compensation
plans and requires additional disclosures for  those companies who elect not  to
adopt  the new method  of accounting. The  Company will continue  to account for
employee purchase rights and stock options under APB Opinion No. 25, "Accounting
for Stock Issued to Employees." SFAS  No. 123 disclosures will be effective  for
fiscal years beginning after December 15, 1995.

10. LONG-TERM DEBT AND OTHER BORROWINGS:
    In March 1996, the Company added to its $2,000,000 equipment credit facility
with a financial institution to finance costs associated with the acquisition of
equipment by adding a second facility for $1,000,000. All borrowings under these
credit facilities are at the bank's prime rate plus 1.00% (9.50% at December 31,
1995)  with  interest  paid  monthly,  and  are  collateralized  by  the related
equipment.  Principal  installments  under  the  $2,000,000  facility  commenced
September  1995  and mature  over  a thirty-six  (36)  month period  as follows:
$687,736, $687,736,  and  $458,491 in  1996,  1997 and  1998,  respectively.  At
December  31, 1995,  no additional amounts  were available  under the $2,000,000
credit facility. The  $1,000,000 facility matures  over a 34  month period.  The
Company is restricted from paying cash dividends but may pay stock dividends.
 
    The  Company in March 1996 modified its  line of credit facility with a bank
to expire February  28, 1997. The  agreement provides for  borrowings up to  the
lesser  of  $2,000,000  or 75%  of  eligible receivables.  Borrowings  under the
agreement bear interest at the bank's prime rate plus 0.50% (9% at December  31,
1995)  and are collateralized by accounts receivable, equipment and other assets
of the Company. At December  31, 1995, the Company  has no borrowings under  the
agreement  and had $1,000,000 available under  the line of credit. In connection
with this modification, on March 8, 1996, the Company issued the lender warrants
to acquire 15,000 shares of the Company's common stock at a price of $11.25  per
share.  These warrants  may be  exercised by  the holder  at any  time until the
expiration date, March 8, 2001.
 
    The two equipment credit facilities and line of credit facility require that
the Company provide financial information to the lender, obtain approval of  the
lender  for any  material disposition of  the collateral except  in the ordinary
course of  business and  meet  certain financial  ratios, minimum  tangible  net
worth, minimum cash and investments and other covenants.
 
    Warrants  to acquire 33,460 shares of common  stock, at a price of $8.96 per
share, issued in connection with the issuance of convertible promissory notes in
1993 and 1992, expired in August 1995.
 
11. COMMITMENTS:
    The Company  leases  its administrative,  sales,  marketing,  manufacturing,
research   and  development  facilities  under  noncancelable  operating  leases
expiring in February  1998 and  August 2000  and 2001.  Under the  terms of  the
leases, the Company is responsible for certain expenses and taxes.

nonexclusive licensing rights of the other party.
 
    Technology developed  by one  party under  the Agreement  is owned  by  that
party,  subject to certain royalty-free non-exclusive  rights of Varian and to a
reassignment right upon termination of the Agreement.
 
    COORDINATED RESEARCH PROGRAM:
 
    In May  1993, the  Company and  Hewlett-Packard Company  ("H-P") modified  a
previous  Coordinated Research Program ("CRP") agreement  by entering into a new
five-year agreement.
 
    This agreement  requires  the  Company  and  H-P  to  exchange  reviews  and
assessments   of   the  Company's   technical  and   applications  developments,
particularly with respect to their potential application to H-P's products.  H-P
has the right to appoint an H-P employee as a member of the Company's Scientific
Advisory  Board,  and the  Company agreed  to use  its best  efforts to  cause a
nominee to be elected to the Board of Directors. Under this agreement, H-P  will
not  have rights to any of the Company's inventions, except that it will jointly
own with the Company any invention developed  by the H-P Member pursuant to  the
agreement  or using the Company's confidential information. As a result, H-P and
the Company will each be entitled to

an  accounting to the  other party, including  through license and cross-license
arrangements with  third parties.  This agreement  may be  terminated by  mutual
consent of either party.
 
    In  connection with the  agreement, the Company  received $1,000,000 in cash
and $230,000 in equipment from H-P in exchange for issuing 439,286 shares of its
Series B preferred stock, which  automatically converted into 137,276 shares  of
common  stock upon the close of the  Company's initial public offering in August
1993.
 
    CONSORTIUM FOR SUPERCONDUCTING ELECTRONICS:
 
    The Company is a  member of the  Consortium for Superconducting  Electronics
formed  to conduct research and development  programs leading to applications of
superconductive electronics. The Company  is presently participating with  other
members  of  the  Consortium in  two  projects  relating to  the  development of
superconductive wireless communications.
 
    The Company has been  granted a non-exclusive, royalty  free license to  all
intellectual  property  conceived  or  first  actually  reduced  to  practice in
connection with  any  work under  a  Consortium  project in  which  the  Company
participates  while the  Company is  a member. The  Company must  pay a one-time
license fee  for commercializing  any invention  covered by  a  "commercialized"
patent  licensed to it  by a university member  or government laboratory member.
The fee is  $50,000 or, in  some cases, $25,000.  (A patent is  "commercialized"
when  the Company's  revenues from  external sales  of products  covered by such
patent exceed $2,000,000). The Company may also be required to pay a license fee
for commercializing any  invention covered by  a "highly commercialized"  patent
licensed  to it by a university member, if the patent is owned solely or jointly
by a university or government laboratory member and if the patent is  determined
to  be a "basic" patent  (i.e., a patent is "basic"  if it represents a singular
contribution of profound commercial  significance) under procedures  established
by  the Consortium. The  initial fee may  not exceed $1,000,000.  In addition, a
second fee  may  be  established  after  five  years  in  accordance  with  such
procedures which may not exceed $5,000,000. (A patent is "highly commercialized"
if the Company's revenues from external sales of products covered by such patent
exceed $10,000,000)
 
    ADVANCED TECHNOLOGY PROGRAM:
 
    In  August 1992, the Company, acting as administrator for and on behalf of a
joint  venture  formed  to  conduct  research  to  develop  a  prototype  hybrid
superconductor/semiconductor  computer under the Department of Commerce Advanced
Technology Program, entered into a  cost-sharing cooperative agreement with  the
U.S.  government. The  U.S. government  is expected  to financially  support the
project in one-year increments over a total five-year period. Under the terms of

and 9,664 shares  of common  stock, at  a price per  share of  $6.08 and  $8.96,
respectively.  As of  March 31,  1996, warrants for  16,447 and  1,087 shares of
common  stock  remain  exercisable,  respectively.  The  warrants,  which   were
immediately exercisable, expire August 5, 1998.
 
    1992 STOCK OPTION/STOCK ISSUANCE PLAN:
 
    The  Company's 1992 Stock Option/Stock Issuance  Plan (the "Plan") serves as
the successor equity  incentive program  to the  Company's 1987  and 1989  Stock
Option  Plans (the "Predecessor Plans"). All outstanding stock options under the
Predecessor Plans will continue  to be governed by  the terms and conditions  of
the Predecessor Plans and the specific instruments evidencing those options, but
no additional options will be granted under the Predecessor Plans.
 
    A  total of  1,580,000 shares  of common  stock are  authorized for issuance
under the  Plan  as of  December  31, 1995.  Such  authorized share  reserve  is
comprised  of 7,812  shares originally  approved under  the Plan,  the aggregate
outstanding shares under the Plan (approximately 689,912 shares) and an increase
of 882,276 shares  under amendments  to the  Plan. The  individuals eligible  to
receive  option grants or  stock issuances pursuant  to the Plan  are limited to
employees (including officers and directors)  and consultants of the Company  or
any  parent or subsidiary corporations. Each non-employee Board member who first
becomes a non-employee Board  member at any  time on or  after January 23,  1995
shall  automatically  be  granted  at  the  time  of  such  initial  election or
appointment an option to purchase 15,000 shares of common stock.
 
    The Plan is divided into two  separate components: the option grant  program
and  the  stock  issuance  program. Under  the  option  grant  program, eligible
individuals may be granted incentive stock options or nonstatutory options.  The
exercise  price of  incentive stock  options granted under  the Plan  must be at
least equal to the fair market value of the common stock of the Company on  date
of grant. The exercise price of nonstatutory options granted under the Plan must
be  not less than 85%  of the fair market  value of the common  stock on date of
grant.  The  stock  issuance  program  allows  eligible  individuals  to  effect
immediate  purchases of the Company's  common stock at fair  market value or for
such consideration as the Compensation Committee deems advisable.
 
    Options granted under the  Plan may be immediately  exercisable for all  the
option  shares, on either a vested or  unvested basis, or may become exercisable
for fully  vested shares  in one  or more  installments over  the  participant's
period  of service. Shares issued under the stock issuance program may either be
vested upon issuance or subject to a vesting schedule tied to the  participant's
period of future service or to the attainment of designated performance goals.
 
    No option may be granted with a term exceeding ten years. However, each such
option  may  be  subject  to  earlier  termination  within  a  designated period
following the optionee's cessation of service with the Company.
 
    In 1992, the Company recognized a compensation charge of $295,000, which  is
being  amortized to the statement  of operations over the  vesting period of the
related options as a  result of a  "deemed" fair market value  in excess of  the
exercise  price of the options in connection with the initial public offering of
the Company's stock. As of December 31, 1995, $91,127 remains to be amortized.

purchase price of such stock under the ESPP cannot be less than 85% of the lower
of  the fair market values  on the specified purchase  date and the beginning of
the offering period. During 1995 employees purchased 101,790 shares for a  total
of  approximately $453,226. At  December 31, 1995,  98,210 shares were available
for future grants under the Plan.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section  145 of the  Delaware General Corporation Law  authorizes a court to
award or  a  corporation's  Board  of  Directors  to  grant  indemnification  to
directors   and   officers  in   terms   sufficiently  broad   to   permit  such
indemnification  under   certain   circumstances  for   liabilities   (including
reimbursement  for expenses incurred) arising under  the Securities Act of 1933,
as amended (the "Securities Act"). Article  VII, Section 6, of the  Registrant's
Bylaws  provides for mandatory indemnification of its directors and officers and
permissible indemnification of employees and other agents to the maximum  extent
permitted  by the Delaware General Corporation Law. The Registrant's Certificate
of Incorporation provides that,  pursuant to Delaware  law, its directors  shall
not  be liable for monetary damages for  breach of the directors' fiduciary duty
as directors  to  the  Company  and its  stockholders.  This  provision  in  the
Certificate  of Incorporation does not  eliminate the directors' fiduciary duty,
and in appropriate circumstances equitable remedies such as injunctive or  other
forms  of  non-monetary  relief will  remain  available under  Delaware  law. In
addition, 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, for knowing  violations of law,  for
actions leading to improper personal benefit to the director, and for payment of
dividends  or approval  of stock  repurchases or  redemptions that  are unlawful
under  Delaware  law.  The   provision  also  does   not  affect  a   director's
responsibilities  under any  other law, such  as the federal  securities laws or
state  or  federal   environmental  laws.  The   Registrant  has  entered   into
Indemnification  Agreements with its officers and  directors, a form of which is
attached  as  Exhibit   hereto  and  incorporated   herein  by  reference.   The
Indemnification  Agreements provide the Registrant's officers and directors with
further indemnification to the maximum extent permitted by the Delaware  General
Corporation  Law."  Reference  is  made  to  that  Section  of  the Underwriting
Agreement contained  in  Exhibit  1.1  hereto,  that  indemnifies  officers  and
directors of the Registrant against certain liabilities.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
    Since  January 1, 1993, the Registrant  has issued and sold (without payment
of any selling commission to any person) the following unregistered securities:
 
    (1) In October 1992 and January 1993, the Company issued and sold to certain
       investors  convertible  promissory  notes  in  the  aggregate  amount  of
       $1,980,000  and warrants to  purchase shares of  Series B Preferred Stock
       (convertible into warrants exercisable for an aggregate of 33,460  shares
       of  Common Stock  at an  effective exercise price  of $8.96  per share of
       Common Stock upon the  closing of the  Company's initial public  offering
       ("IPO")  in August, 1993). Each  of such notes had  an interest of 9% per
       annum. The aggregate purchase price of such warrants equaled $20,000.

    (2) In January 1993,  in connection with the  renegotiation of an  equipment
       lease  agreement  with Dominion  Ventures, Inc.,  the Company  issued two
       warrants exercisable  to  purchase shares  of  Series B  Preferred  Stock
       (convertible  into warrants exercisable for  an aggregate of 7,577 shares
       of Common Stock  at an  effective exercise price  of $8.96  per share  of
       Common  Stock upon the closing of the  IPO). Such warrants will expire on
       August 5, 1998.
 
    (3) In January, the Company issued  to Comdisco, Inc. a warrant to  purchase
       shares  of  Series  B  Preferred Stock  (convertible  into  a  warrant to
       purchase 2,087 shares of Common Stock  at an effective exercise price  of
       $8.96  per  share of  Common Stock  upon  the closing  of the  IPO). Such
       warrant was issued in exchange for forgiveness of interest payments under
       an equipment lease agreement and will expire on August 5, 1998.
 
    (4) In May 1993, in connection with the acquisition of Tristan Technologies,
       Inc., the Company issued  342,588 shares of Common  Stock and options  to
       purchase 20,936 shares of Common Stock to the former employees of Tristan
       in exchange of all the outstanding shares and options of Tristan.
 
    (5) In June 1993, the Company issued and sold to certain investors shares of
       Series  B Preferred Stock convertible into an aggregate of 412,838 shares
       of Common Stock  at an effective  per share purchase  price of $8.96  and
       issued  and  sold to  an investor  21,670  shares of  Common Stock  at an
       effective per share  purchase price  of $4.48,  all in  exchange for  the
       cancellation  of  outstanding indebtedness  of $2,065,907,  $1,500,065 in
       cash and equipment valued at $230,000.
 
    (6) Since January 1, 1993, the Registrant has sold and issued 356,281 shares
       (assuming no  exercise of  stock options  after March  31, 1996)  of  its
       Common Stock to employees, independent directors and consultants pursuant
       to  exercises of  options under its  1992 Stock  Option Plan, predecessor
       plans and employment agreements.
 
    (7) Since January 1, 1993, the Registrant has sold and issued 101,790 shares
       (assuming no sales of stock after November 30, 1995) of its Common  Stock
       to employees pursuant to its 1994 Employee Stock Purchase Plan.
 
    (8)  In March  1996, the  Registrant sold and  issued a  warrant to purchase
       15,000 shares of  its Common Stock  to Silicon Valley  Bank (the  "Bank")
       pursuant  to modifications of the  terms of a line  of credit between the
       Bank and the Registrant. These modifications included an increase in  the
       amount of the line of credit from $1,000,000 to $2,000,000 as well as the
       creation of an equipment term loan in the amount of $1,000,000.
 
    The  issuances  of  the  above  securities were  deemed  to  be  exempt from
registration under  the  Act  in  reliance  on Section  4(2)  of  such  Act,  or
Regulation  D thereunder, or Rule 701 promulgated  under Section 3(b) of the Act
as transactions by an issuer not  involving any public offering or  transactions
pursuant to compensatory benefit plans and contracts relating to compensation as
provided  under Rule 701. The recipients  of securities in each such transaction
represented their intention to  acquire the securities  for investment only  and
not  with a view to or for sale  in connection with any distribution thereof and
appropriate legends were affixed to  the share certificates and warrants  issued
in  such  transactions.  All  recipients  had  adequate  access,  through  their
relationships with the Registrant, to information about the Registrant.

    The Registrant  hereby undertakes  to  provide to  the Underwriters  at  the

    Insofar  as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant  pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation or the Bylaws  of the Registrant,  the Underwriting Agreement,  or
otherwise, the Registrant has been advised that in the opinion of the Securities
and  Exchange  Commission  such  indemnification  is  against  public  policy as
expressed in the Securities Act, and is, therefore, unenforceable. In the  event
that  a  claim  for indemnification  against  such liabilities  (other  than the
payment by the Registrant of expenses  incurred or paid by a director,  officer,
or controlling person of the Registrant in the successful defense of any action,
suit  or proceeding) is asserted by such director, officer or controlling person
in connection with  the securities  being registered  hereunder, the  Registrant
will,  unless  in the  opinion of  its counsel  the matter  has been  settled by
controlling precedent,  submit  to  a  court  of  appropriate  jurisdiction  the
question  of  whether such  indemnification by  it is  against public  policy as
expressed in the Securities Act and  will be governed by the final  adjudication
of such issue.
 
    The Registrant hereby undertakes that:
 
        (1)  For purposes of determining any liability under the Securities Act,

                   RE:    REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

         We have examined the Registration Statement on Form S-1 (File No. 
33-________) originally filed by Conductus, Inc. (the "Company') with the 
Securities and Exchange Commission (the "Commission') on May 15, 1996, as 
thereafter amended or supplemented (the "Registration Statement'), in 
connection with the registration under the Securities Act of 1933, as 
amended, of up to 1,000,000 shares of the Company's Common Stock (the 
"Shares'). The Shares include an over-allotment option granted by the 
Company to the Underwriters to purchase up to 150,000 additional shares of the 
Company's Common Stock and are to be sold to the Underwriters as described in 
the Registration Statement for resale to the public. As your counsel in 
connection with this transaction, we have examined the proceedings taken and 
are familiar with the proceedings proposed to be taken by you in connection 
with the sale and issuance of the Shares.

         It is our opinion that, upon conclusion of the proceedings being 
taken or contemplated by us, as your counsel, to be taken prior to the 
issuance of the Shares and upon completion of the proceedings being taken in 
order to permit such transactions to be carried out in accordance with the 
securities laws of the various states where required, the Shares, when issued 
and sold in the manner described in the Registration Statement, will be 
legally and validly issued, fully paid and non-assessable.

         We consent to the use of this opinion as an exhibit to said 
Registration Statement, and further consent to the use of our name wherever 
appearing in said Registration Statement, including the prospectus 
constituting a part thereof, and in any amendment or supplement thereto.


                                            Very truly yours,


                                            Gunderson Dettmer Stough

                                   APPENDIX A
                                STATEMENT OF WORK

1.   PROJECT OBJECTIVE

Conductus and Siemens will specify a SUPERCONDUCTING MRI RECEIVER and 
determine its performance specifications. Conductus will develop and build a 
prototype of said specified SUPERCONDUCTING MRI RECEIVER and demonstrate its 
performance on a Siemens Magnetom Open 0.2 T MRI system.  The SUPERCONDUCTING 
MRI RECEIVER is expected to be a small, general-purpose superconducting MRI 
surface coil and cryogenic receiver assembly for operation on a Siemens Open 
0.2 T MRI system. The receive coil will have an effective diameter of 
approximately 4 cm.  The period for develop-ing and building of the prototype 
SUPERCONDUCTING MRI RECEIVER is expected to conclude by December 31, 1996.

1.1   CONDUCTUS OBLIGATIONS

Conductus shall use reasonable efforts to:

a) Design and build a SUPERCONDUCTING MRI RECEIVER;

b) Demonstrate performance and operating characteristics of the 
   SUPERCONDUCTING MRI RECEIVER on a Siemens Magnetom Open 0.2 T MRI machine; 
   and

c) Provide the SUPERCONDUCTING MRI RECEIVER and necessary support to enable a 
   U.S. Siemens customer, preferably Dr. Jonathan Lewin, Cleveland to make MRI 
   images at a Siemens research site in the U.S.

1.2   SIEMENS OBLIGATIONS

Siemens shall use reasonable efforts to:

a) Provide Conductus with coil interface specifications available at Siemens 
   for the Magnetom 0.2 T MRI, such other information as is reasonably 
   necessary for Conductus to perform its tasks under this AGREEMENT and such 
   other information as is mutually agreed by the PARTIES;

b) Provide, at times and locations as agreed to by the PARTIES, site access, 
   machine time and operator time at a Magnetom Open 0.2 T system that is 
   geographically convenient to Conductus, for the purpose of conducting 
   hardware tests;

c) Subject to prior agreement of the PARTIES, provide a conventional (i.e. not 
   superconducting) MRI receiver with a coil diameter of equivalent geometry 
   to that of the coil of the SUPERCONDUCTING MRI RECEIVER, to allow for a 
   performance comparison; and

<PAGE>

                                   -15-

d) Subject to prior agreement between the PARTIES, site access, machine time 
   and operator time at a Siemens research site, to enable a US Siemens 
   customer, preferably Dr. Jonathan Lewin, Cleveland to make MRI images with 
   the prototype of the SUPERCONDUCTING MRI RECEIVER.
